Clinical PresentationPatients are often well-appearing after an ALTE at the time they present to medical care. Each adrenal consists of two functionally distinct endocrine glands: the cortex, derived from mesenchymal cells, and the medulla, derived from neuroectodermal cells. Glucocorticoid insufficiency can be primary, resulting from the direct insult to the adrenal cortex, or secondary, from adrenocorticotropic hormone (ACTH) or corticotropin-releasing hormone (CRH) hyposecretion as a result of pituitary or hypothalamic dysfunctions. Primary adrenal insufficiency affects glucocorticoid and mineralocorticoid secretion and may be fatal if untreated.
Secondary and tertiary adrenal insufficiencies occur commonly after the discontinuation of glucocorticoids. All patients with primary adrenal insufficiency complain of fatigue, anorexia, and weight loss.
Evaluating a patient with suspected adrenal insufficiency is a three-step process: establishing the diagnosis, differentiating between primary and secondary adrenal insufficiencies, and looking for the cause of adrenal insufficiency.
These patients should be further evaluated by the cosyntropin (Cortrosyn) stimulation test (CST), which can be performed at any time during the day.
The insulin tolerance test (ITT) and metyrapone test are generally used for the evaluation of patients suspected to have secondary adrenal insufficiency.
Patients with Addison’s disease require lifelong replacement with glucocorticoids and mineralocorticoids. Acute adrenal insufficiency (adrenal crisis) is a life-threatening emergency, which usually manifests with nausea, vomiting, abdominal pain, and shock. The overall incidence of AI in critically ill patients is less than 10%, but an incidence as high as 50% in a patient with septic shock has been reported.
Intensive care unit (ICU) patients with hemodynamic instability, despite fluid resuscitation (especially in the presence of shock), should be tested for AI. More than 90% of circulating cortisol is bound to cortisol- binding globulin (CBG) and albumin. Hydrocortisone, 50 mg IV every 6 to 8 hours is an adequate replacement dose for critically ill patients with suspected adrenal insufficiency. Autoimmune destruction of the adrenal glands is the most common cause of primary adrenal insufficiency in the United States.
Almost all patients with primary adrenal insufficiency present with fatigue, anorexia, and weight loss. Primary and secondary adrenal insufficiencies are differentiated through measurement of the plasma ACTH level. Acute adrenal insufficiency is a medical emergency that should be treated with IV hydrocortisone and fluids as soon as the diagnosis is suspected.
Adrenal insufficiency should be suspected in critically ill patients with septic shock or hypotension refractory to intravenous fluids and pressors.
Diseases related to adrenal hyperfunction are relatively rare, but they have significant mortality and morbidity if untreated. Cushing’s syndrome (CS) is composed of symptoms and signs associated with prolonged exposure to inappropriately high levels of plasma glucocorticoids. Harvey Cushing initially described the clinical features of CS in the early 20th century, including centripetal obesity, moon face, hirsutism, and plethora; however, such a classic clinical picture is not always present and a high index of suspicion is usually required. Patients with ectopic ACTH syndrome caused by small cell lung carcinoma lack many of the typical clinical features. Screening for CS may be done by a 24-hour urinary free cortisol (UFC) determination, 1-mg dexamethasone suppression test (DST), or midnight salivary cortisol test (Fig. The 1-mg DST is performed by the administration of dexamethasone, 1 mg at 11 pm, followed by measurement of the plasma cortisol level at 8 am. The combined DST-CRH stimulation test may be used for differentiating between CS and pseudo-Cushing’s syndrome. Certain drugs, such as phenytoin, phenobarbitals, and rifampin, increase the clearance rate of dexamethasone, resulting in false- positive results during a DST.
Because of the challenging nature of CS, reaching the proper diagnosis requires a stepwise evaluation, knowledge of the limitations of each test, and avoidance of shortcuts (see Fig. Once Cushing’s syndrome is biochemically confirmed, the plasma ACTH level should be measured, preferably in the morning.
A combination of the CRH stimulation test and an overnight high-dose DST are used to differentiate ectopic CS from Cushing’s disease. Surgical (trans-sphenoidal) removal of the ACTH-secreting pituitary tumor is the treatment of choice.
Cushing’s syndrome caused by an adrenal adenoma is usually cured by laparoscopic unilateral adrenalectomy. Evaluation for the plasma circadian rhythm, midnight plasma cortisol level, 2-day low-dose dexamethasone suppression test (LDDST), and combined LDDST-CRH test were described by the workshop as second-line screening tests.
Screening for Cushing’s syndrome may be done by a midnight salivary cortisol level assay, 1-mg DST, or 24-hour urinary free cortisol test. Certain drugs, such as phenytoin, phenobarbitals and rifampin, increase the clearance rate of dexamethasone, resulting in false-positive results during DSTs. Because of the challenging nature of Cushing’s syndrome, obtaining a proper diagnosis requires a stepwise evaluation, knowledge of the limitations of each test, and avoidance of shortcuts. Once Cushing’s syndrome has been biochemically confirmed, the plasma ACTH level should be measured to differentiate between ACTH-dependent and ACTH-independent CS.
Conn first described primary hyperaldosteronism in 1955 in a patient with an adrenal adenoma. Two forms of familial hyperaldosteronism (FH) have been described: FH type I and FH type II. The clinical picture varies from asymptomatic to symptoms related to hypertension, hypokalemia, or both.
The workup of a patient for primary hyperaldosteronism involves the following steps: screening tests for primary hyperaldosteronism, establishing the autonomy of aldosterone secretion, and determination of the source of hyperaldosteronism (Fig.
Although hypokalemia in a hypertensive patient is suggestive of hyperaldosteronism, normokalemia does not exclude the diagnosis. IV administration of 2 L of isotonic saline over 4 hours in the recumbent patient is a less favored way to establish the diagnosis. The treatment goals are to reduce the morbidity and mortality associated with hypertension, hypokalemia, and cardiovascular damage by normalization of blood pressure and aldosterone levels.
Medical treatment is reserved for patients with IHA or those with APAs who are poor surgical candidates.
For the first few weeks after surgery, patients should increase their salt intake to compensate for hypoaldosteronism that may occur because of chronic suppression of the renin-angiotensin system.
Spironolactone and eplerenone should be discontinued for 6 weeks before biochemical testing and potassium needs to be replaced to the normal range.
Familial hyperaldosteronism type I, or glucocorticoid-remediable hyperaldosteronism (GRH), is an autosomal dominant disease in which aldosterone is synthesized in the zona fasciculata of the adrenal gland under the control of ACTH.6 Affected individuals are usually younger than 40 years, exhibit hypertension resistant to standard therapy, and have a family history of primary hyperaldosteronism or a cerebrovascular accident at a young age. There are no consensus statements for the evaluation and therapy of patients with hyperaldosteronism. There is some disagreement about the role of adrenal venous sampling in patients with biochemical proof of hyperaldosteronism. Patients with PHEO may have paroxysmal hypertension (48%) or persistent hypertension (29%), or be normotensive (13%).9 Wide fluctuations in blood pressure and resistance to antihypertensive medications are typical of those with pheochromocytoma. The triad of headaches, palpitations, and diaphoresis suggests the diagnosis of PHEO, but absence of these symptoms does not exclude the disease. Patients with indeterminate levels of plasma-free metanephrines should have their urinary metanephrine and serum catecholamine levels measured (Fig. In patients with nondiagnostic ranges of plasma and urine catecholamine and metanephrine levels, and clinical features suggestive of PHEO, repeating the measurements at the time of symptoms or proceeding with dynamic testing may be used to support or exclude the diagnosis.10 Clonidine normally suppresses plasma catecholamines, a response that is lost in PHEO. The list of medications and interfering substances varies according to what is measured-plasma or urine catecholamines or their metabolites-and to the specific assay used. Chemical shift MRI has a sensitivity of 93% to 100% and specificity of approximately 50% in detecting pheochromocytomas. Surgery for PHEO has shifted from the open conventional procedure to the laparoscopic approach over the past decade. The triad of headaches, palpitations, and diaphoresis suggests the diagnosis of pheochromocytoma, but absence of these symptoms do not exclude the disease. Beta blockers should not be used in patients with suspected pheochromocytoma until alpha blockade has been instituted.
Plasma-free metanephrines have 99% and 97% sensitivity for sporadic and familial pheochromocytomas, respectively. Adequate medical preparation is essential and should be initiated at least 10 to 14 days before surgery. In prepubertal children, boys and girls, androgen excess manifests as increased rate of growth in height and skeletal maturation, leading to premature epiphyseal fusion and short adult height. Androgen excess with onset at puberty causes premature skeletal maturation and short adult height in boys. Of the various causes of adrenal hyperandrogenism, nonclassic (adult-onset) congenital adrenal hyperplasia (CAH), and androgen-producing adrenal tumors are discussed in this section.
Nonclassic congenital adrenal hyperplasia (NCAH) is an autosomal recessive disorder, with most patients exhibiting a defect in 21-hydoxlyase enzyme activity, resulting in decreased cortisol production. Glucocorticoids, oral contraceptives (OCPs), antiandrogens such as aldactone, or a combination of these medications are used to treat women with NCAH. Nonclassic congenital adrenal hyperplasia (NCAH) is mostly caused by a defect in the 21-hydroxylase enzyme and manifests as hyperandrogenism in young adolescent and adult women. The main differential diagnosis for NCAH is polycystic ovary syndrome, which is about 40 to 50 times more common. Importance  Detailed, nationally representative data describing high-risk populations and circumstances involved in insulin-related hypoglycemia and errors (IHEs) can inform approaches to individualizing glycemic targets. Objective  To describe the US burden, rates, and characteristics of emergency department (ED) visits and emergency hospitalizations for IHEs.
Main Outcomes and Measures  Estimated annual numbers and estimated annual rates of ED visits and hospitalizations for IHEs among insulin-treated patients with diabetes mellitus. We used recent, nationally representative data from 2007 through 2011 to estimate the burden and rates of insulin-related hypoglycemia and errors (IHEs) resulting in emergency department (ED) visits and subsequent hospitalizations, and identify high-risk groups and precipitating factors for IHEs. For the National Health Interview Survey (NHIS), the Core questionnaire (Sample Adult and Sample Child components) was used. Data collection for the NEISS-CADES project is considered a public health surveillance activity by federal human subjects oversight bodies and does not require human subject review or institutional review board approval.14 Data collection for the NHIS is approved by the institutional review board at the National Center for Health Statistics, Centers for Disease Control and Prevention. Each NEISS-CADES record is accompanied by a sample weight based on inverse probability of selection, adjusted for nonresponse and hospital nonparticipation, and poststratified to account for changes in the number of US ED visits each year. To estimate rates of ED visits and hospitalizations for IHEs in relation to insulin exposure, we divided NEISS-CADES–derived estimates of ED visits or hospitalizations for IHEs by NHIS-derived estimates of insulin-treated patients. In an estimated 22.9% of ED visits for IHEs, more than 1 type of insulin product was documented in the medical record (Table 3). Insulin is an important component of diabetes treatment but remains complex to manage and poses serious risk of hypoglycemia.22 These national data quantify the burden and severity of IHEs, identify patient groups at higher risk for these events, and describe precipitating factors that could be targeted by prevention efforts. Enhanced prevention efforts should target commonly identified IHE precipitants.48 Although meal planning is a well-recognized component of diabetes self-management education,49,50 the most commonly documented IHE precipitant in this study was meal-related misadventure, suggesting that further emphasis on meal planning in diabetes patient education efforts may be needed. Administration of the wrong insulin product (eg, rapid-acting vs long-acting agents) was the second most commonly documented IHE precipitant. Our findings should be interpreted in the context of the limitations of public health surveillance data. Insulin-related hypoglycemia and errors are clinically significant causes of ED visits and hospitalizations for ADEs, particularly among very elderly patients with diabetes.

Metatarsalgia, a term that refers to pain developing in the area across the plantar forefoot, is a common reason for consulting in orthopedic surgery. Orthopedic treatment, including a change in the type of footware and the use of padded inserts, is the first therapeutic option, with surgery being indicated when these conservative measures fail. We present four clinical cases of patients surgically treated using Weil osteotomies, in whom the symptoms of metatarsalgia persisted. At 12 months of follow-up, all patients were satisfied with the outcome, and were able to walk without limitations in distance and with no footware restrictions (Figure 3). Modification of the original Weil technique by addition of a second osteotomy enables greater elevation of the metatarsal head and a decrease in recurrent metatarsalgia at gait push off [1,3,4]. Percutanous osteotomy has proven to be a valid technique that yields results similar to open osteotomy for the treatment of hallux valgus and metatarsalgia [5,6].
In conclusion, percutanous surgery is an effective surgical option for salvage treatment of open Weil ostotomies with screw fixation.

The adrenal cortex consists of three concentric zones: The outer glomerulosa secretes the mineralocorticoid aldosterone, the intermediate fasciculata secretes cortisol, and the inner reticularis secretes androgens.
Autoimmune destruction of the adrenal glands (Addison’s disease) is the most common cause of primary adrenal insufficiency in United States (70%-90%), whereas tuberculosis is now the second most common cause worldwide. Less frequently, ACTH deficiency may be caused by pituitary macroadenomas, pituitary surgery or radiation, and parasellar diseases. Other clinical and laboratory manifestations of primary adrenal insufficiency are presented in Table 1. ITT is considered the gold standard test for the evaluation of hypothalamic-pituitary-adrenal (HPA) axis. The test has not been well validated for the evaluation of adrenal function and its current role in the evaluation of adrenal function is limited to research protocols. When the biochemical workup is consistent with primary adrenal insufficiency, computed tomography (CT) scanning of the adrenal glands may help with the differential diagnosis.
Patients may be previously undiagnosed or have chronic primary adrenal insufficiency, with no or inadequate glucocorticoid replacement. Diagnostic workup in a patient with no history of AI should include a plasma sample for cortisol and ACTH level determination, immediately followed by an IV bolus of hydrocortisone, 100 mg, and adequate fluid replacement (normal saline).
The concept of total adrenal insufficiency has gradually been replaced by relative adrenal insufficiency, which may be fatal in critically ill patients.


A random serum cortisol level determination and the standard CST are the two commonly used tests for evaluating adrenal function in these patients.
In the following sections, Cushing’s syndrome, primary hyperaldosteronism, pheochromocytoma, and androgen-producing adrenal tumors are reviewed. The rapid course and high levels of ACTH and cortisol often result in hyperpigmentation, myopathy, peripheral edema, glucose intolerance, and hypokalemic alkalosis.
A more than 50% increase in the ACTH level after the CRH test and more than an 80% reduction in the morning cortisol level (8-9 am) after taking 8 mg dexamethasone at 11 pm during a high-dose DST is consistent with a pituitary source, and in the presence of a pituitary adenoma, almost establishes the definitive diagnosis of CS. Experienced neurosurgeons usually achieve 70% to 80% long-term remission rates following surgery. Adrenal carcinoma is typically an aggressive tumor with a poor prognosis; surgical resection at an early stage, along with lifelong mitotane therapy started soon after surgery, offers the only chance for cure or long-term remission. When the tumor is not resectable, bilateral adrenalectomy is performed to correct hypercortisolemia. The consensus emphasized that if the diagnosis of Cushing’s is suspected clinically but initial screening tests are normal, the patient should be re-evaluated at a later date and invasive procedures postponed. In our experiences and in spite of being labor intensive, the combined LDDST-CRH test is of significant value in differentiating CS from pseudo-Cushing’s syndrome.
FH type I, or glucocorticoid-remediable hyperaldosteronism (GRH), is an autosomal dominant disease characterized by a chimeric gene between the 11β-hydroxylase and aldosterone synthase, with varying degrees of hyperaldosteronism, which responds to exogenous glucocorticoids. Patients may have headaches, polyuria, nocturia, polydipsia, parasthesias, weakness, and muscle cramps. Although most patients with hyperaldosteronism are not hypokalemic, a low serum potassium level may be noted, either spontaneously or after thiazide or loop diuretic use. The test can be done while the patient is on antihypertensive medications (except spironolactone and eplerenone), without requiring postural stimulation.
Because of differences in therapy, distinguishing an aldosterone-producing adenoma APA and idiopathic hyperaldosteronism is important (Table 2). Adrenal venous sampling is performed during continuous ACTH infusion and relies on demonstration of a gradient for plasma aldosterone in unilateral disease. Unilateral adrenalectomy, usually by a laparoscopic approach, results in normalization of hypokalemia and improvement in hypertension in all patients. Although some experts have advocated screening all hypertensive patients for hyperaldosteronism, we recommend screening only high-risk patients.
Adrenal venous sampling is selectively used in some centers, whereas some other centers perform the test in almost all patients.7 In our opinion, if there is a clear adenoma on CT scan on one of the adrenals and the results of the posture test also suggest APA, the patient can be assumed to have the disease and should be referred for surgery.
Although their true prevalence is unknown, they occur in about 0.3% of hypertensive patients.
Extra-adrenal pheochromocytomas (paragangliomas) occur in about 15% of cases in the superior and inferior para-aortic areas, including the Zuckerkandl organ (75%), bladder (10%), thorax (10%), and head, neck, and pelvis (5%). Familial predisposition to pheochromocytoma is seen in patients with multiple endocrine neoplasia (MEN) types IIA and IIB, von Hippel-Lindau disease, neurofibromatosis type 1, and familial paragangliomas. Norepinephrine-secreting tumors are associated with sustained hypertension and norepinephrine and epinephrine-secreting tumors are associated with labile hypertension. Attacks are usually precipitated by emotional stress, exercise, anesthesia, abdominal pressure, or ingestion of tyramine- containing foods. Plasma-free metanephrines (total free normetanephrine and metanephrine) have 99% and 97% sensitivity, respectively, for sporadic and familial PHEOs, but there is approximately a 10% to 15% false-positive rate for sporadic PHEO. Medications should be stopped for 3 to 5 days, except labetalol, which needs to be discontinued for 2 weeks (causes analytic interference with some assays).
PHEOs are usually larger than 3 cm in diameter and tend to be cystic, with areas of necrosis with increased size. The low lipid content of PHEO tumors results in a signal intensity decrease from the in-phase to opposed-phase T1-weighted image.
Patients should have electrocardiography and cardiac echocardiography before surgery, with further cardiac evaluation if any abnormality is detected. Most experts’ opinions are based on personal experience in centers with large referral bases.
However, there is approximately a 10% to 15% false-positive rate for sporadic pheochromocytoma. The primary adrenal androgens, dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS sulfate), are under ACTH control and have little intrinsic androgenic activity. In female neonates, androgen excess causes female pseudohermaphroditism (ambiguous genitalia).
In addition, boys exhibit penile enlargement, hair growth in androgen-dependent areas, deepening of the voice, and other secondary sexual characteristics (isosexual precocious puberty). In girls, it manifests as primary or secondary amenorrhea, different degree of virilization, and increased skeletal maturation, resulting in short adult height. A decrease in size of the testicles, testosterone secretion, and spermatogenesis caused by inhibition of gonadotropin secretion may occur.
Exogenous androgen intake for body building or to increase erythropoiesis may cause acne, hirsutism, and oligomenorrhea or amenorrhea in women and small testes, gynecomastia, and impaired spermatogenesis in men. The associated increased ACTH secretion stimulates adrenal steroid production upstream of the defective enzyme, resulting in increased androgen secretion. Meal-planning misadventures and insulin product mix-ups are important targets for hypoglycemia prevention efforts.
Coders also record narrative descriptions of the ADE, including preceding events, physician diagnosis, clinical and laboratory testing, treatment administered by emergency medical services (EMS) or ED staff, and discharge disposition.
Visits for allergic reactions, local effects (eg, injection site pain), nonhypoglycemic effects (eg, headache alone), and accidental needle sticks were excluded.
Estimates and their corresponding 95% CIs derived from 2007-2011 NEISS-CADES and NHIS data were divided by 5 to obtain average annual estimates and 95% CIs.
When documented, almost half (45.9%) involved meal-related misadventures (eg, neglecting to eat shortly after taking a rapid-acting insulin or not adjusting insulin regimen in the presence of reduced caloric intake) (Table 4). Based on prior cost estimates of ED visits for hypoglycemia,23 ED visits for IHEs may have cost well over $600 million during the 5-year study period.
A previous study27 based on NEISS-CADES found insulin to be one of the most commonly implicated drugs in adverse events treated in EDs. Reducing ED visits for adverse events related to injectable antidiabetic agents has been recognized as a national priority for improving the health of Americans in a new Healthy People 2020 goal.66 Reaching this goal will probably require balancing glycemic risks in vulnerable older patient populations and augmenting prevention efforts targeted at key IHE precipitants, such as meal-related misadventures and insulin product mix-ups.

An estimated 19-60% of stroke patients present within 3 hours of the stroke and 14-32% of those arrive within 2 hours of symptom onset.4-9Those who do utilize EMS comprise the majority of patients presenting within the 3-hour window, although this may reflect a greater sense of urgencyon the patient?s or bystander?s part rather than reduced transport time.

Open surgery using Weil osteotomy techniques is widely accepted to treat metatarsalgia when orthopedic management fails.
This condition is usually associated with abnormal pressure-loading at the heads of the metatarsals and is accompanied by plantar hyperkeratosis [1].
Metatarsal drop produces selective pain during the midstance phase of the gait cycle (second rocker) and leads to formation of a callosity under the metatarsal head. At present, the most widely used surgical treatment is open distal metatarsal osteotomy using a Weil technique with screw fixation. DMMO enables surgical salvage without the need to remove the screw, by performing the ostotomy at a slightly more proximal position, at the level of the metatarsal neck.
The percutaneous technique does not requires removal of the synthesis material, and it is associated with a lower incidence of dorsiflexion contracture of the toes. The endocrine cells of the adrenal medulla are the chromaffin cells, which are part of the sympathetic nervous system and produce the catecholamine epinephrine. Megestrol acetate, an appetite stimulator used in some patients with advanced cancer or cachexia related to AIDS may be associated with secondary AI.
Skin hyperpigmentation, initially on the extensor surfaces, palmar creases, and buccal mucosa, results from increased levels of ACTH and other pro-opiomelanocortin–related peptides, including melanocyte- stimulating hormone. The ITT is contraindicated in older patients (>65 years) and those with acute illness, seizure disorders, or cardiovascular-cerebrovascular disease. Enlarged adrenal glands or calcifications suggest an infectious, hemorrhagic, or metastatic cause. Most patients can be educated to self administer hydrocortisone, 100 mg IM, and reduce the risk of an emergency room visit. Abdominal tenderness and fever are common findings, and adrenal crisis may manifest as an acute abdomen.
Hydrocortisone should be continued, 50 mg every 8 hours, while awaiting laboratory results. Hypotension in patients with adrenal insufficiency may mimic hypovolemic or septic shock and should be considered in the differential diagnosis.
During severe illness caused by a marked decrease in the CBG level, albumin has a more significant influence on the total concentration of cortisol. After hemodynamic improvement, a gradual taper of hydrocortisone, depending on the patient’s condition, should be instituted. The endogenous causes are divided into ACTH-dependent and ACTH-independent CS, as shown in Box 1.
Weight gain is almost always present, except in ectopic ACTH secretion (EAS) caused by malignancy. Agitated depression and lethargy are among the most common psychiatric abnormalities seen in CS patients, but paranoia and overt psychosis may occur. Female patients with adrenal carcinomas often present with signs and symptoms of virilization (hirsutism and acne), breast atrophy, deepening of the voice, temporal hair recession, and clitoromegaly caused by hypersecretion of androgens, along with the cortisol. Currently, a 24-hour UFC test (with simultaneous urinary creatinine level measurement) is the most widely used initial screening test but a midnight salivary cortisol determination is becoming a good alternative. Measurement of the 24-hour UFC during the second day of the low-dose DST is of lesser value, and usually does not add any further to the diagnostic accuracy of the baseline 24-hour UFC test. It is always important to remember the effect of increased levels of CBG on serum cortisol levels during pregnancy or in women taking estrogens.
Discrepant or inconclusive test results require re-evaluation of the entire clinical picture and a biochemical workup, because CS is almost always a progressive disease. If the CRH stimulation test and DST results are not concordant and MRI does not show a pituitary adenoma, then inferior petrosal sinus sampling to distinguish ectopic from Cushing’s disease is indicated.
An undetectable cortisol level postoperatively, when the patient is off glucocorticoids, is considered to be an excellent indication of long-term cure.
Medical therapy with ketoconazole, metyrapone, aminoglutethimide, or mitotane may be considered for patients with a limited life expectancy or for alleviation of hypercortisolemic symptoms before surgery. A 24-hour UFC assay, overnight 1-mg DST, and midnight salivary cortisol determination were described as first-line screening tests for CS.
The workshop recommended the use of bilateral inferior petrosal sinus sampling (BIPSS) in patients whose clinical, biochemical, or radiologic study results are discordant or equivocal. Some investigators have proposed a prevalence as high as 10% in hypertensive patients.5 Women in their fourth to sixth decade of life are affected more often than men.
FH type II is an autosomal dominant disorder of both the aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism (IHA).
Both spironolactone and eplerenone should be discontinued for 6 weeks before biochemical testing and after the potassium level reaches the normal range. Diuretics, ACE inhibitors, and ARBs should be discontinued for 2 weeks before the tests and potassium needs to be replaced to the normal range. The test may entail risk in older patients, those with uncontrolled hypertension, or those with decompensated heart disease. Side effects include painful gynecomastia, nausea, headaches, impotence, and irregular menstruation. If untreated, the disease can have severe consequences, such as myocardial infarction, heart failure, cerebrovascular accident, and death. Paragangliomas tend to occur in younger patients <20 years) and are uncommon in those older than 60 years. Genetic screening in patients with apparently sporadic pheochromocytoma is recommended for the following categories of patients: age younger than 20 years, bilateral disease, multiple paragangliomas, or family history of pheochromocytoma or paraganglioma. Large cystic PHEOs may not be associated with hypertension because most of the catecholamines are metabolized within the tumor before being released into circulation. Normalization of the plasma metanephrine level or a decrease in the plasma catecholamine levels by at least 50%, into the normal range for the assay, is considered a normal response. Patients should abstain from caffeinated beverages and alcohol for 24 hours and medications listed in Box 3 for 3 to 5 days before biochemical evaluation. In a patient suspected to have PHEO, CT scanning of the abdomen and pelvis should be performed first, followed by CT of the chest and neck if no tumor is found (Fig. PHEO tumors typically exhibit signal isointensity with the liver, kidneys, and muscle on T1-weighted images and a characteristically bright, high signal intensity on T2-weighted images (Fig.
The specificity of iobenguane sulfate131I is very high, 95% to 100%, and the sensitivity is about 85%. It is preferable that patients be admitted to the hospital 1 day before surgery for close observation. In patients with aggressive tumors, combination chemotherapy (cyclophosphamide, vincristine, dacarbazine) or iobenguane sulfate131I-tagged radiotherapy may be considered, but results have not been promising.
Although there are still disagreements about the best initial screening test for PHEO, serum metanephrine or 24-hour urinary metanephrine level determination appears to be the most favored initial test of choice.
However, they are converted to androstenedione and then to testosterone (and estrogen) in both the adrenal gland and peripheral tissues.
In women, hirsutism, acne, menstrual irregularities, male pattern baldness, infertility, decreased breast tissue, increased muscle mass, android body habitus, and clitoromegaly may occur, depending on the degree of hyperandrogenism. Hyperprolactinemia may cause an increase in serum DHEAS and androstenedione levels by direct stimulation of the adrenal gland.
It is a rare disease, with an incidence of 1 per 600,000 to 1,600,000 and a prevalence of 4 to 12 per 1,000,000. Definitions of other variables, including IHE location, clinical presentation, BG levels, hypoglycemia treatments, diabetes therapy, and precipitating factors are provided in eTable 1 in the Supplement.
Estimates based on small numbers of cases (<20) or with a coefficient of variation greater than 30% were considered statistically unstable and are noted in the tables.
Accompanying 95% CIs were calculated accounting for variability in both numerator and denominator estimates and assuming statistical independence (as these components were derived from separate surveys).20 These rate estimates were then used to calculate rate ratios (RRs) of ED visits and hospitalizations for IHEs associated with different patient groups. The estimated median age of patients who presented to EDs for IHEs was 60 years for patients treated with insulin alone and 67 years for patients treated with insulin and at least 1 oral antidiabetic agent.
Direct comparisons of our findings with those of previous studies are limited by methodologic differences among studies.
Based on the more recent data in this study, IHEs accounted for 1 of every 8 estimated ED visits for ADEs among the very elderly (≥80 years), who sought ED evaluation and were hospitalized for IHEs at rates 2 and 5 times higher, respectively, than those 45 to 64 years. Second, because medical history information is limited in the ED medical record, the contributions of risk factors for hypoglycemia (eg, DM type, intensity and duration of insulin therapy, glycemic control, concomitant medications, and comorbid conditions) were not assessed. Health care quality metrics should evolve based on the most current glycemic control guidelines, and the effects of changing guidelines, quality metrics, and prevention strategies should be evaluated by means of ongoing national surveillance. Blood Sugar Levels Ks4 Prevention Treatment 2 Type being overweight or obese raises the risk of becoming diabetic they are risk factors but do not mean that an obese Nausea or vomiting; inability to keep down fluids.
As blood sugar levels remain high Type-1 diabetes often leads to unintentional weight loss Some patients have no obvious waring signs before falling into a diabetic coma Simple blood tests can diagnose diabetes.
Diabetes itchy skin symptoms are often overlooked and not seen as early Type 2 diabetes symptoms since skin changes Treatment for ALL Diabetics and Impaired Glucose Tolerance . Injuries medical problems or chronic conditions can often be prohibitively expensive for other organizations to handle.
The recognition of a problem by the bystander, stroke severity, presence of intracranial hemorrhage, age, sense of urgency, unemployment, and race (African American) are predictors of EMS use. However, the presence of the osteosynthesis screw and the distal position of the osteotomy significantly complicates salvage procedures.
When one or more of the metatarsals are longer than the other, pain is produced during the push-off phase (third rocker), and in general, the callosities are more distal and less focally located [2].


When surgical treatment does not yield satisfactory results, the presence of the synthesis screw and the distal position of the osteotomy significantly complicate salvage surgery [1-3]. This variability in clinical presentation has also been noted in the pre-hospital setting.70History and Physical ExaminationThere are several goals of the ED evaluation of patients after an ALTE. Secondary adrenal insufficiency manifests more insidiously with lack of skin hyperpigmentation, salt craving, metabolic acidosis, and hyperkalemia, because mineralocorticoid secretion is intact.
Most individuals with normal adrenal function achieve much higher cortisol levels at 60 minutes after cosyntropin injection. A low or normal-range ACTH level, with a low cortisol level, confirms the diagnosis of secondary or tertiary adrenal insufficiency.
In rare circumstances, CT-guided percutaneous fine-needle aspiration of enlarged adrenal glands may help establish the diagnosis. Serial follow-up of adrenal function in critically patients with clinical features suggestive of AI is recommended.
A subset of patients with septic shock may benefit from physiologic stress dose glucocorticoids. An elevated salivary cortisol level in most cases should be confirmed by a 24-hour UFC test before referral to surgery. Another clinical scenario that may be associated with normal screening tests is cyclic CS, which needs to be ruled out by periodic evaluation.
Localizing tumors that produce ectopic ACTH is accomplished by chest and abdominal CT studies, followed by neck CT if no source is found. The workshop briefly discussed the promising results from the midnight salivary cortisol test, which we believe should be part of the diagnostic workup for most patients suspected to have CS, particularly if early disease is suspected. We usually carry out BIPSS in most of our patients with ACTH- dependent CS who have no clear adenoma on pituitary MRI. A solitary aldosterone-producing adenoma (65%) and bilateral idiopathic hyperplasia (30%) are the most common subtypes of primary aldosteronism.
The degree of hypertension is usually moderate to severe, and may be refractory to conventional antihypertensive agents. Its presence reduces the secretion of aldosterone and thus should be corrected before the laboratory evaluation of hyperaldosteronism. Measurement of the 24-hour urinary potassium level can be useful in assessing the cause of a low potassium level, including surreptitious vomiting or laxative abuse.
Hypertension may be controlled by calcium channel blockers, beta blockers, or α1-adrenergic receptor blockers, which do not significantly affect the biochemical workup for hyperaldosteronism. The blood pressure response to spironolactone before surgery often predicts the blood pressure response to surgery in those with an APA. Serum potassium and magnesium levels should be monitored to avoid hyperkalemia and hypomagnesemia. Other symptoms include orthostatic hypotension, weight loss, dyspnea, polyuria, polydipsia, visual blurring, focal neurologic symptoms, and change in mental status. In general, a plasma-free metanephrine level more than three or four times the upper normal has 100% specificity for PHEO. Nasal decongestants, some antihypertensives, antidepressants, antipsychotics, and cocaine affect iobenguane sulfate131I uptake and have to be withheld for 1 to 3 days before the study.
NCAH affects from 1% to 10% of hyperandrogenic women, depending on their ethnic background.
The most commonly identified IHE precipitants were reduced food intake and administration of the wrong insulin product.
Among ED visits for IHEs at which taking the wrong insulin was documented, the most commonly reported error was mixing up long-acting and rapid-acting insulin products. Third, the specific insulin brand, formulation, and delivery system were not always documented, which limited the ability to assess differences in ED visits and hospitalizations for IHEs across specific insulin products. Diabetes is a disorder characterised by increased level of sugar (glucose) in blood – hyperglycemia.
Communities should encourage 9-1-1 activation and use for patients with symptoms of acute stroke.A. We present a series of patients in whom persistent postoperative metatarsalgia was resolved by percutaneous osteotomies. In all cases, salvage surgery consisted in percutaneous distal metatarsal mini-invasive osteotomies (DMMO), with immediate loadbearing using a postoperative shoe with a rigid sole (Figure 2). As always, a rapid cardiorespiratory assessment is needed to rule out the need for immediate life?sustaining interventions. Addison’s disease may coexist with other autoimmune conditions, such as type 1 diabetes, hypothyroidism, or hypoparathyroidism. Secondary and tertiary adrenal insufficiencies only affect cortisol secretion, because ACTH has only a minor role in regulation of aldosterone secretion. Fatigue, hyponatremia, and hypoglycemia are some of the clinical manifestations in secondary adrenal insufficiency. Metyrapone blocks the final step in cortisol biosynthesis, resulting in a reduction in cortisol secretion, which in turn stimulates ACTH secretion. Patients with tuberculous adrenal insufficiency usually have evidence of active systemic disease. The dose is adjusted based on clinical status, including the presence or absence of orthostatic hypotension, hypertension, and electrolyte imbalance. In patients with equivocal biochemical results, a trial of 2 or 3 days of stress dosage glucocorticoids is appropriate, as long as it will be discontinued in the absence of any significant hemodynamic improvement. Such therapy has not yet been proven to be effective and safe in all patients with septic shock. CS has profound effects on bone, causing poor linear growth in children and osteoporotic vertebral collapse and pathologic fractures in adults. A normal sleeping pattern is necessary for an accurate salivary cortisol level measurement for the evaluation of CS.
A flat response of ACTH to CRH during the test suggests an adrenal cause, but a more than 50% increase in the ACTH level during the test is consistent with Cushing’s disease. An octreotide scan may be of some value in patients with ectopic CS and negative imaging studies. After pituitary tumors are treated, lifelong medical follow-up is necessary to detect early recurrence, monitor hormone replacement, and treat any complications related to the tumor. Potassium supplementation is stopped in most patients without any underlying heart disease at the beginning of the salt-loading test. The presence of a solitary adrenal tumor with a normal contralateral adrenal gland is usually consistent with an APA. Eplerenone is a steroid-based antimineralocorticoid that blocks the aldosterone receptor selectively and has a better side effect profile. Bilateral adrenal pheochromocytomas (5%-10% of cases) are usually seen as part of familial syndromes. Urinary vanillylmandelic acid (VMA) measurement has a high false-negative rate (41%) and should not be used for screening purposes, but a positive result has approximately 86% and 99% specificity for sporadic and hereditary PHEOs, respectively. Because of the potential for inducing a hypertensive crisis, beta blockers should never be used without simultaneously using alpha blockers.
An adrenal tumor with a noncontrast Hounsfield unit (HU) lower than 10 is extremely unlikely to be PHEO. We usually prefer CT scanning over MRI as the initial imaging study with a biochemical workup diagnostic for PHEO because of cost and widespread availability.
Beta blockers should be added only after alpha blockade has been instituted to prevent unopposed alpha receptor activation, which may result in hypertensive crisis. Peak levels occur in the third decade of life and decline progressively to 25% of peak levels around the age of 80 years. Both CAH and NCAH are associated with an increased incidence of adrenal adenomas and testicular adrenal rest tumors.13 This warrants CT scanning of the adrenal glands and testicular ultrasonography (men) in patients with biochemical confirmation.
Similarly, we did not make detailed comparisons between patients treated with insulin alone and those treated with insulin and oral antidiabetic agent(s) because documentation of concurrent oral diabetes therapy may have been incomplete. Asthma An excellent resource with useful video audio images and references relating to asthma. EMS AssessmentEMS should have protocols in place to make stroke a priority dispatch and to rapidly assess, treat, and transport patients. When the biochemical work up suggests secondary or tertiary adrenal insufficiency, magnetic resonance imaging (MRI) of the pituitary gland is indicated if glucocorticoid therapy as the cause of the secondary adrenal insufficiency has been ruled out.
Patients may need to double the dose of fludrocortisone or increase salt intake during the summer, when the weather is hot. Lifelong glucocorticoid replacement therapy should not be sanctioned on the basis of an equivocal biochemical test result in an acutely ill patient. Values of UFC above three or four times upper normal for the assay are usually diagnostic for CS, especially when repeated and confirmed. Idiopathic adrenal hyperplasia may be accompanied by adrenocortical nodules and is associated with lower aldosterone levels and less severe hypertension, compared with adenomas. The left ventricular hypertrophy is disproportionate to the level of blood pressure and improves after treatment of hyperaldosteronism, even if hypertension persists. Low or suppressed PRA during therapy with angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) suggests hyperaldosteronism. During day 4 of salt loading, a 24-hour urine sample must be collected by the patient for aldosterone, sodium, potassium, and creatinine level testing.
Determination of plasma aldosterone levels before and 2 hours after an upright posture (with ambulation) and a plasma 18-hydroxycorticosterone level can further help distinguish APA from IHA. However, spironolactone is the favored initial treatment, because it is more potent and costs less.
Malignant pheochromocytomas (10% of adrenal cases) have a higher prevalence in ectopic PHEOs and lower prevalence in familial PHEOs.
If the plasma-free metanephrine concentration is normal, no other diagnostic test is necessary except in those with small tumors found during workup for familial disease, patients with a history of PHEO or, rarely, patients with a dopamine-producing paraganglioma. Uptake of iodine by the thyroid gland should be blocked with potassium iodide (SSKI; five drops three times a day, starting on the day of iobenguane sulfate131I and 3 days afterward).
Calcium channel blockers (CCBs) can be used for medical preparation or may be added if there is persistent or labile hypertension. The main differential diagnosis for NCAH is polycystic ovary syndrome (PCOS), which is about 40 to 50 times more common (Table 3).12 Distinguishing the two only on clinical grounds is difficult, because both can be associated with varying degrees of hyperandrogenism and ovulatory dysfunction. The consensus statement from the Lawson Wilkins Pediatric Endocrine Society and the European Society for Pediatric Endocrinology about CAH almost exclusively discusses the diagnosis and management of the classic form of the disease. Tumors are usually larger than 6 cm, invade the capsule, metastasize early, and typically recur after surgery.

Patients with secondary or tertiary adrenal insufficiency do not need mineralocorticoid replacement. All patients should wear some form of identification indicating their adrenal insufficiency status. About 90% of patients with ACTH-dependent CS have a pituitary cause and the rest are ectopic in origin. Alternatively, potassium-sparing diuretics such as amiloride or triamterene may be used, but they lack the mineralocorticoid receptor antagonist benefits. If the iobenguane sulfate131I study is negative, fluorodeoxyglucose positron emission tomography (PET) scanning or oxidronate (Octreoscan) may be used with some success for visualization (see Fig. The nonspecific α1-adrenergic blocker phenoxybenzamine has a greater side effect profile and may result in prolonged hypotension after surgery.
After surgery, blood pressure and blood glucose levels need to be closely monitored, antihypertensive agents withheld, and normal saline infusion continued. Surgical resection at an early stage, along with lifelong mitotane therapy starting soon after surgery, offers the only chance for cure or long-term remission. Second, determine the likelihood of an etiology that requires urgent or even emergent treatment. Moon face and supraclavicular and dorsocervical fat pads (buffalo hump) are nonspecific and accompany obesity from other causes. Patients with an inconclusive adrenal CT scan or discordant results are referred for adrenal venous sampling. The diagnosis of malignant pheochromocytoma relies on the presence of metastases and not on the histology of the tumor. Given the wide scope of etiologies, this presents a significant clinical challenge.The importance of a thorough history and careful physical examination cannot be overemphasized.
The lack of a commercially available 1-μg cosyntropin dose may be a potential for error.
Another supportive measure is correction of hypokalemia with the addition of aldactone at the end of biochemical workup. Lifelong follow-up is necessary for all patients, with closer follow-up of those with familial, large, extra-adrenal, or bilateral tumors.
Cyanosis and apnea are the most common presenting symptoms.7 One should remember that these events are, by nature, very frightening and some details could be inexact. A normal physical examination, however, does not exclude significant underlying pathology.The ED diagnostic evaluation of infants after an ALTE is extremely controversial. The differential diagnosis of ALTE is quite large and testing for all possible etiologies is not feasible. Evidence-based guidelines do not exist nor does the presence of an abnormal test result indicate causality. A recent consensus document noted that ?there is no standard minimal work-up in the evaluation of an ALTE?.71Several studies have addressed the question of the appropriate ED evaluation of these infants. All patients presenting to a Pediatric ED after an ALTE were reviewed retrospectively for a one-year period.6 In the study timeframe, there were 130 patients with a total of 196 apneic episodes. The most commonly performed diagnostic tests included urinalysis, chest x-ray and ?blood tests? (blood count and chemistries).
Blood tests were performed in a similar number of cases and were abnormal in 17% of patients. However, the abnormalities were considered mild (usually mild hyponatremia, mild hypokalemia or leukocytosis) and did not alter management. The study considered significant medical interventions based upon diagnostic tests ordered in the ED for patients after an ALTE.
This patient had a history of prematurity and anemia and had been transfused previously on several occasions. Blood cultures and cerebrospinal fluid studies were obtained in 62% and 38% of patients, respectively. Over a one-year period, 65 infants were evaluated after an ALTE with a standardized investigation protocol.7 The diagnostic evaluation included blood count, serum chemistries, lactate, ammonia, blood amino acids, urinalysis (and culture if positive), urine organic acids, urine for reducing substances, urine toxicology screen, pertussis and RSV studies, chest x-ray and EKG.
Chest x-rays were significantly abnormal in 17 patients, 9 of which had a negative history and physical examination.
All infants were alive at 3 years of follow-up; but, of the eight patients with recurrent ALTEs, all had significant underlying disorders. Patients were categorized based upon the contributions of the history and physical examination and diagnostic testing in the establishment of a  diagnosis.
However, in this group, a patient with upper GI bleed was the only one with an abnormal blood test.
All remaining blood assays (counts, chemistries, gases, metabolic screens, coagulation profile) were non-contributory as were CSF studies. In cases where there is a thorough history, physical exam finding, or a suspicion of a metabolic defect, care should be taken to save additional blood aliquots and arrange for their storage. Many metabolic markers are present only at the time of the event and will be missed if samples are drawn at a later time.
Urgent sub-specialty consultation (genetics, metabolism, endocrine) may facilitate this process.The most appropriate ED diagnostic evaluation of patients after an ALTE remains unclear. A focused workup based upon the findings from the history and physical examination seems most appropriate.
