It is estimated that more than 1.2 million adult Australians will have diabetes by the end of the decade, with only half of those affected being aware of their condition. Type 2 diabetes mellitus (T2DM) is characterised primarily by insulin resistance, in which increased insulin is required to produce a normal blood glucose level.
All patients aged 55 years and over should be screened for diabetes, as should younger people who have particular risk factors such as obesity, family history, hypertension or belonging to a high risk ethnic group.
Initial management of T2DM targets insulin resistance by lifestyle modification (weight loss and exercise) and pharmacological therapies (metformin and thiazolidenediones). Insulin therapy becomes necessary when glycaemic targets are not reached despite treatment.
Therapy for T2DM should be monitored by capillary blood glucose monitoring by the patient and by periodic testing of HbA1c levels.
It is important not to treat the blood glucose level only, but also to recognise and treat hypertension, dyslipidaemia, smoking and obesity to reduce morbidity and mortality from microvascular and cardiovascular disease. DIABETES MELLITUS is a syndrome of abnormal glucose metabolism characterised by hyperglycaemia.
T2DM has become epidemic in the past few decades, with a dramatic increase in its incidence worldwide. Insulin resistance is a condition in which increased insulin is required to produce a normal biological response (ie, a normal blood glucose level). While insulin resistance exists in virtually all individuals with T2DM, it is frequently present in the metabolic syndrome (which often precedes the onset of T2DM) even in the absence of hyperglycaemia. The WHO definition is based on the presence of T2DM or impaired glucose tolerance (IGT) plus the presence of any two of the above abnormalities including microalbuminuria.
Before developing overt T2DM, patients hypersecrete insulin to maintain normal blood glucose levels. An international expert committee on the diagnosis and classification of diabetes mellitus recently revised criteria for the diagnosis of IFG. Patients identified as having prediabetes should have a review of lifestyle and cardiovascular disease risk factors. In the past there has been disagreement as to whether the FPG or the OGTT should be the initial screening test used for diagnosis of diabetes. The OGTT is not recommended as the first step in screening (ADA and WHO) but rather as a confirmation test. The HbA1c test - an index of average blood glucose levels during the previous three months - remains a valuable tool to monitor glycaemia and an indicator of therapeutic response, but it is not recommended for the screening or diagnosis of diabetes because of the lack of local and international laboratory standardisation of reference ranges and the confounding effect of other conditions (such as pregnancy, uraemia, haemoglobinopathies, blood transfusion and anaemia). The initial management of T2DM targets insulin resistance, the underlying pathogenetic factor causing the metabolic disturbance. In patients who are unable to adopt the necessary lifestyle modifications, or who do so but show signs of worsening glycaemia, an oral antihyperglycaemic agent should be prescribed. The thiazolidinediones (rosiglitazone and pioglitazone) are another class of oral antihyperglycaemic agents which reduce insulin resistance via a different mechanism from metformin. Results of the United Kingdom Prospective Diabetes Study showed that most patients with T2DM required treatment with multiple oral antihyperglycaemic agents to achieve recommended glycaemic targets.
The meglitinides (nateglinide and repaglinide) are relatively short-acting agents that increase pancreatic insulin secretion.
The only other class of oral antihyperglycaemic agents are the alpha-glucosidase inhibitors (acarbose).
Before starting insulin treatment in T2DM, it is important to make sure the patient has been compliant with their prescribed oral antihyperglycaemic agent therapy and that secondary causes of hyperglycaemia are not present. It is important not to delay the introduction of insulin treatment in patients with secondary treatment failure. The patient with insulin-requiring T2DM starts with a once daily long-acting insulin (eg, Protaphane) injection at bedtime. The newer insulin-analogue preparations have allowed more physiological insulin to be used. The HbA1c target may be individualised for each patient, but the usual goal should be a level of 7%. Just as important as glycaemic control in the management of T2DM is the detection of comorbidities, followed by aggressive treatment to achieve recommended targets.

Pancreatic cancer is the fourth and fifth most common cancer in men and women, respectively. Of pancreatic cancers, 60% develop in the pancreatic head and 40% develop in the body and tail.
The diagnosis and staging of pancreatic cancer is accomplished through imaging tests and pathologic diagnosis (see Figure 1).
Magnetic resonance imaging (MRI) with gadolinium enhancement compares favorably with CT in the assessment of local tumor extent, relation to vascular structures, lymph node involvement, and distant metastases. Several studies have suggested increased sensitivity of endoscopic ultrasound (EUS) compared with conventional, single-phase CT for detecting and local staging of pancreatic cancer. The role of endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of pancreatic disease has diminished in recent years as a result of improved noninvasive and less-risky imaging techniques. Biopsy of a pancreatic mass or metastasis may be done percutaneously under CT guidance or by EUS with FNA. The standard operation for adenocarcinoma in the pancreatic head or uncinate process is pancreaticoduodenectomy, or Whipple procedure. Although chemotherapy and radiotherapy are not curative, they can offer some clinical benefits, including reducing primary tumour burden, shrinkage of the borderline resectable cancer for resection,,improvement of symptoms, and prolongation of survival. The palliation of symptoms is arguably the most important goal in patients with locally advanced and metastatic disease. Neuroendocrine tumors (NETs) are rare tumors (incidence rate, 5 cases per 1 million person-years) that arise from endocrine cells within or near the pancreas and account for less than 5% of all pancreatic tumors. When a NET is suspected, imaging tests are used to locate the primary tumor and determine the presence of metastases (Figure 3). NETs confined to the pancreas should be surgically resected after symptoms of hormonal excess have been treated and controlled (see Table 2).
Up to 90% of pancreatic cysts are inflammatory pseudocysts arising from acute or chronic pancreatitis.
In asymptomatic patients, EUS allows improved characterization of cyst features and also simultaneous aspiration of cyst fluid for chemical analysis. Mucinous cystic neoplasms and IPMNs should be resected because they have potential for malignant transformation. Dual phase contrast-enhanced computed tomography scanning is the initial test of choice in the diagnosis and staging of pancreatic cancer. Radical pancreaticoduodenectomy (Whipple procedure) is the treatment of choice for patients with resectable pancreatic cancer.
Although chemotherapy and radiation therapy have roles in the management of unresectable pancreatic cancer, palliation of symptoms is the primary therapeutic goal.

Return of Investment for Bariatric Surgery – weighing in the options for good returns. How much are we willing to pay for an improvement in health?  What if the initial “investment” put into surgery allows an actual return within several years, given the improvements in health and the consequent reduced treatment involved? The benefits of weight loss have been well-documented, and those having gone through bariatric surgery having a lower long-term mortality, less medical problems (better control of diabetes, hypertension, hyperlipidaemia and obstructive sleep apnoea), less need for follow-up medical consultations and medications.  As a result of these benefits, better employability has been demonstrated for job applicants of a lower BMI.

When hospitals fail to turn and reposition their patients, skin breakdown (like pressure sores) develop.
Individuals with prediabetes or T2DM are at increased risk of cardiovascular disease and usually have what is called the metabolic syndrome. Screening should be performed first with a test of fasting plasma glucose level (FPG), with the oral glucose tolerance test being performed only when the FPG test is equivocal. Medications which increase pancreatic insulin secretion (sulfonylureas) are also often required.
When explaining why insulin has become necessary, it is important to remind patients of the natural history of T2DM and the benefits of better glycaemic control. The HbA1c target may need to be individualised for each patient, but the goal should be an HbA1c level of 7%. It is associated with insulin deficiency - a relative or absolute impairment in pancreatic insulin secretion, along with varying degrees of peripheral resistance to the action of insulin. In Australia, the AusDiab study reported that in 2000 7.4% of the population aged 25 or over had diabetes.
Insulin resistance is caused by both acquired (weight gain, reduced exercise) and genetic factors.
In those patients with insulin resistance who have normal blood glucose levels, fasting insulin levels are elevated.
Currently, the National Cholesterol Educational Program (NCEP) Adult Treatment Panel III (ATP III) guidelines are most commonly used. Eventually the ability of pancreatic beta-cells to secrete insulin becomes impaired in the face of continued insulin resistance. Patients with IGT have a stronger association with cardiovascular disease risk factors, cardiovascular disease events and mortality 7,8 compared with IFG (which in itself implies a higher cardiovascular disease risk than normal blood glucose levels).
Fasting is defined as no consumption of food or beverage other than water for at least 8 hours before testing. The American Diabetes Association (ADA) expert committee has recommended that the FPG should be the diagnostic test of choice, both for clinical and epidemiological purposes. Capillary blood glucose testing using a blood glucose meter is too imprecise for diagnosis and should only be used for self-monitoring.
Testing should be performed at age 45 and over if a person is obese (body mass index >30), has a first degree relative with T2DM, or has hypertension.
Metformin is almost always the primary drug of choice in T2DM as it improves glucose tolerance by enhancing insulin sensitivity. Their hypoglycaemic effect may not be seen for 4 to 6 weeks and is similar (in terms of HbA1c reduction) to metformin and other oral antihyperglycaemic agents, but may be longer lasting.
After insulin resistance has been reduced, the next step is to use medications which increase pancreatic insulin secretion. Their main use is in reducing postprandial hyperglycaemia, and they should be administered immediately before meals.

They work by delaying intestinal carbohydrate absorption by competitively inhibiting the enzyme responsible for breakdown of disaccharides and complex polysaccharides. We know from the United Kingdom Prospective Diabetes Study that patients with T2DM have less than 25% of normal insulin secretion 6 years after diagnosis.
During titration of the insulin regimen, patients may be reluctant to accept higher insulin dosages. Very short-acting (insulinaspart and insulin-lispro) and long-acting (glargine, detemir) insulin-analogue preparations have been developed as well as mixtures. The serial HbA1c level is the best correlate of microvascular complications, while home blood glucose monitoring helps the stabilisation and education process.
An HbA1c of 6.5% is the preferred target for younger patients with T2DM, also for those with early microvascular complications and patients with a family history of diabetic nephropathy.

The diagnostic and therapeutic approaches outlined here integrate the AGA guidelines for the diagnosis and treatment of pancreatic ductal adenocarcinoma (Figure 1).
Based on animal experiments, the aromatic amines present in cigarette smoke, meats, and fish oil may be the specific pathogenic factor predisposing to neoplastic transformation. Depending on the location of the cancer, symptoms may include abdominal pain, anorexia, weight loss, and jaundice.
Physical examination findings include jaundice, cachexia, a palpable abdominal mass, ascites, left cervical lymphadenopathy (Virchow's node), a palpable gallbladder (Courvoisier's sign), and migratory superficial thrombophlebitis (Trousseau's syndrome). The best initial imaging test for diagnosis and staging of pancreatic cancer is contrast-enhanced, dual-phase, helical CT, with thin cuts through the pancreas.
MRI can improve differentiation of a pancreatic cancer from chronic pancreatitis and offers simultaneous assessment of the pancreatic and bile ducts by heavily T2-weighted imaging (MRCP).
The greatest advantage of EUS is that it allows fine needle aspiration (FNA) of the tumor to provide a tissue diagnosis. Biopsy is indicated in unresectable disease to confirm the diagnosis and aid in decision making regarding chemotherapy and radiation therapy.
Staging laparoscopy with or without laparoscopic ultrasound improves accuracy through the detection of small hepatic or peritoneal metastases, widespread sampling of regional lymph nodes, and direct visualization of the primary tumor and its relation to peripancreatic vessels. Pancreatic cancer is resectable if the tumor is confined to the pancreas and does not have encasement of adjacent surrounding major vessels (superior mesenteric artery or vein, portosplenic confluence, celiac trunk, or aorta), does not have extensive peripancreatic lymph node involvement, or does not have distant metastases.
This involves resection of the pancreatic head, duodenum, common bile duct, distal stomach, and gallbladder. These modalities have been studied in locally metastatic disease and advanced disease and as surgical adjuvant therapies. Patients with pancreatic cancer may develop debilitating symptoms of pain (neural plexus invasion), jaundice (biliary obstruction), or vomiting (gastric outlet obstruction). NETs can occur sporadically or as part of inherited genetic syndromes such as multiple endocrine neoplasia type 1, neurofibromatosis, von-Hippel Lindau disease and tuberous sclerosis complex.
Patients with metastatic disease can be managed medically with octreotide, chemotherapy (streptozocin), or radiographic embolization of the primary tumor and metastases. Fluid may be analyzed for cytology, tumor markers (carcinoembyonic antigen [CEA]), and amylase. Resection should also be considered for serous cystademomas that are symptomatic or enlarging.
International consensus guidelines 2012 for the management of IPMN and MCN of the pancreas. American hospitals recently implemented the chart on the left in an effort to prevent pressure sores. While treatment of hospital bedsores is expensive, it is a requirement to maintain the patient’s health. Patients with decubitus ulcers are at a higher risk of infection (like sepsis) and disease by way of their open wounds. Type 1 diabetes mellitus (T1DM) is characterised by destruction of the pancreatic beta islet cells resulting in an absolute deficiency of insulin. 1 This study also found that for every diagnosed case of diabetes there is an undiagnosed case.
It is often accompanied from early on in the disease process by other cardiovascular risk factors, including increased abdominal fat, hypertension, elevated glucose levels and dyslipidaemia - a constellation of features known as the metabolic syndrome.
However, routine measurement of fasting insulin levels is of little value as a clinical test.
This optimises the sensitivity and specificity for predicting future diabetes and increases the frequency of diagnosis of prediabetes by about 20%. However, both IGT and IFG are similarly associated with an increased risk of diabetes, estimated at 10% progression each year from prediabetes to diabetes. We now know from studies such as the Diabetes Prevention Program (DPP) 9 and the Finnish Diabetes Study 10 that we can prevent or substantially delay the progression from IGT to T2DM through intensive lifestyle treatment, such as exercise and diet therapy. In asymptomatic patients, the FPG and results of the OGTT should be confirmed by retesting on another day.
However, the World Health Organization (WHO) has recommended the use of the OGTT in some circumstances. Certain ethnic groups (Pacific Islanders, Indians, Chinese and Aboriginal and Torres Strait Islanders) should be tested at age 35 and over, because of the high incidence of T2DM in these groups. Pharmacological therapies specifically aimed at reducing insulin resistance (metformin and thiazolidenediones) may help.
It also has the advantage of improving glycaemic control without the risk of weight gain and hypoglycaemia. Considerable data have accumulated recently to show that thiazolidinediones may have beneficial effects on the atherogenic process within the vessel wall, 18 as well as reducing blood pressure and producing a less atherogenic lipid profile. Thiazolidinediones have only recently been listed on the Pharmaceutical Benefits Scheme, and their use in Australia will be restricted to prescribing them in combination with either metformin or sulfonylureas for patients in whom combination therapy with metformin plus sulfonylureas is contraindicated or not tolerated. The insulin secretagogues include the sulfonylureas and the newer meglitinides (not available on the Pharmaceutical Benefits Scheme).
13 This is why oral antihyperglycaemic agents eventually lose effect in almost all T2DM patients. However, it is important to remind patients of the natural history of T2DM when explaining why insulin has become necessary. Insulin has no upper dose limit, and it is the target HbA1c level which is important, not the actual dose required to achieve that level of control.
The long-acting insulin analogue preparations are not currently available on the Pharmaceutical Benefits Scheme.
It also alerts patients to sudden or gradual deterioration in glycaemic control and in their recognition of hypoglycaemia. In older patients, particularly the more frail elderly patient, the goal is not so much the HbA1c level but rather avoiding symptomatic hyperglycaemia and hypoglycaemia. Cardiovascular disease prevention with regular low-dose aspirin, cessation of smoking and restoration of ideal body weight are all needed to help reduce morbidity and mortality from microvascular and cardiovascular disease.
He has been author or coauthor of more than 300 publications in the international literature in endocrinology and diabetes.
Some patients can present with pancreatitis due to obstruction of the pancreatic duct by the mass. CT allows assessment of the primary tumor, local invasiveness, regional lymph node involvement, liver metastases, and peritoneal spread (Figure 2). Diagnostic features on ERCP include an irregular solitary pancreatic duct stenosis more than 1 cm long, an abrupt cutoff of the main pancreatic duct, or an obstruction of both pancreatic and bile ducts (double-duct sign). The AGA guidelines have recommended staging laparoscopy if there is a high likelihood of unresectability that has not been confirmed by imaging tests.
Unfortunately, because of late presentation and delay in diagnosis, only 20% of patients present with resectable disease.
Reconstruction involves pancreaticojejunostomy, hepaticojejunostomy, and gastrojejunostomy. The AGA guidelines have stated "all patients with unresectable locoregional or metastatic pancreatic cancer should be considered for inclusion into investigational trials." For years, single-agent gemcitabine has been the standard first-line agent for patients with advanced metastatic pancreatic cancer based on studies that demonstrated a significant clinical response (decreased pain, increased functional status), even in the absence of a measurable tumor response. Most primary NETs arise within the gastrinoma triangle, composed of the joining of the cystic and common hepatic ducts, second and third portions of the duodenum, and border of the body and tail of the pancreas. Contrast-enhanced CT and MRI may be used as initial tests; however, they have a low yield for small tumors. A positive mucin stain of cyst fluid may also be helpful in ruling in a mucinous cystic neoplasm.

We took this image on the internet we consider would be probably the most representative pictures for franklin skidders on craigslist. The pressure sore flow chart diagram offers insight into the steps a hospital nurse or doctor should take to prevent bedsores in hospital patients.
Bedsore patients also suffer painful decubitus ulcer wounds which require debridements and surgery.
As it is often asymptomatic in its early stages, T2DM can remain undiagnosed for many years. Significantly, the metabolic syndrome markedly increases the risk for the development of cardiovascular disease in individuals whether or not they have developed diabetes. The OGTT needs to be carried out after an overnight fast following three days of adequate carbohydrate intake (greater than 200g per day).
Patients at increased risk of developing diabetes should be retested every 3 years, or annually if they are at high risk.
All people with prediabetes or clinical cardiovascular disease (myocardial infarction, angina or stroke) and women with the polycystic ovary syndrome or a previous history of gestational diabetes are at high risk and should be screened, regardless of age.
Realistic targets should be set regarding weight loss, keeping in mind that a 5kg weight loss can reduce insulin resistance by 25%-50% 16 as well as improving blood pressure and lipid levels. The United Kingdom Prospective Diabetes Study showed that metformin was the only therapy during intensive control of hyperglycaemia that reduced the risk of myocardial infarction in subgroup analysis of obese patients with T2DM.
These effects make them excellent choices in treating patients with the metabolic syndrome (most T2DM patients). Pioglitazone is the only thiazolidinedione which has an indication for use in combination with insulin in T2DM.
Sulfonylureas are the secretagogues of choice; they are usually added to existing therapy directed towards reducing insulin resistance.

It is the least potent of the oral antihyperglycaemic agents, with no more than a 1 percentage point reduction in HbA1c likely to be achieved by addition of this drug. Secondary treatment failure is defined clinically when blood glucose levels deteriorate after an initially good response to oral antihyperglycaemic agents.
As well, mention should be made of the benefits of better glycaemic control: reducing the risk of microvascular complications and improving well being. There is extensive evidence that insulin is effective when administered in combination with any of the oral antihyperglycaemic agents. The newer agents have allowed insulin-requiring patients to achieve good glycaemic control with fewer episodes of hypoglycaemia.
Diagnosis and classification of diabetes mellitus, provisional report of a WHO consultation. Therefore, in elderly patients presenting with acute pancreatitis without an obvious cause, pancreatic cancer should be considered. The AGA guidelines have suggested that EUS has the greatest role in detecting small tumors missed by CT and in tissue acquisition.
Importantly, these findings are nonspecific, because they may also be observed in chronic pancreatitis. For example, it may be elevated in benign conditions such as choledocholithiasis and cholangitis and up to 10% of pancreatic cancer do not synthesize CA19-9 even in advanced stages. Critics have argued that the theoretical risk of peritoneal seeding and procedure complications outweigh the benefit. The long-term prognosis is poor, even among those who undergo resection and have tumor-free margins (5-year survival rate after resection is 10%-25%).
Although the perioperative mortality in high-volume centers is less than 2%, several short- and long-term complications can occur, including anastomotic leaks and ulcerations, dumping syndrome, delayed gastric emptying and bile gastritis. However, recent data suggests a 5-fluorouracil based combination regimen known as FOLFIRINOX (5-FU, leucovorin, oxaliplatin and irinotecan) leads to better survival and higher response rate in selected patients with good performance status.1 Patients with locally advanced cancer with good performance status may be considered for combined gemcitabine or 5-fluorouracil-based chemotherapy and external beam radiation, which have been shown to improve median survival compared with radiation therapy alone.
While majority of NETs are non-functional, small subset secrete hormones that can result in various clinical syndromes (Table 1).
EUS is a more sensitive test for detecting small pancreatic neuroendocrine tumors and allows simultaneous FNA for tissue diagnosis. Biologic agents targeting pathways implicated in proliferation of NET cells (Everolimus, an mTOR inhibitor) and angiogenesis (Sunitinib, a tyrosine kinase inhibitor) have been shown to improve progression free survival in metastatic pancreatic NETs in randomized control trials.2,3 Debulking of primary and metastatic disease may also be considered for patients with debilitating symptoms related to tumor secretory products. However, once a bedsore deteriorates to a Stage III or Stage 4 decubitus ulcer, it becomes harder to heal. Type 2 diabetes mellitus (T2DM) is a different disorder, characterised primarily by insulin resistance in muscle, liver and fat. The prevalence of T2DM has doubled in the last 20 years and it is estimated that more than 1.2 million Australians 25 years and over will have diabetes by 2010.
At present there are numerous people in the community who have diabetes but remain undiagnosed for many years. The classic symptoms of diabetes include polyuria, polydipsia, and unexplained weight loss.
The OGTT better identifies high-risk subjects for diabetes and cardiovascular disease (ie, those with IGT) and also those diabetic patients with a normal FPG but elevated 2-hour plasma glucose levels (as occurs in some ethnic groups; eg, Chinese). When both tests are performed, a result indicative of diabetes for either one is diagnostic (subject to confirmation by retesting on another day).
17 Gastrointestinal complaints may occur in some patients with metformin therapy, but are minimised if patients are started on a low dose that is titrated slowly to a maximum of 3g daily. Whether the beneficial effects on surrogate markers for cardiovascular disease translate into a reduction in cardiovascular disease events is yet to be shown in clinical studies. Unlike metformin, these agents are safe for patients with a high creatinine level and are an alternative to metformin as first line therapy in patients who cannot tolerate the gastrointestinal side effects of metformin. Secondgeneration sulfonylureas (gliclazide, glipizide, glimepiride and glibenclamide) have structural characteristics that allow them to be given in much lower doses than their predecessors.
Acarbose occasionally has a role in patients who are just above the target HbA1c level when treated with maximal doses of metformin and a sulfonylurea. The patient is usually on maximal doses of more than one oral antihyperglycaemic agent with a suboptimal HbA1c level. Nevertheless, nocturnal hypoglycaemia is possible and should be avoided as far as possible, as it constitutes a significant risk in elderly patients, especially those who live alone. The most effective combination seems to be insulin with metformin, particularly in terms of weight gain, glycaemic control and reducing insulin requirements.
Overall, less than 5% of patients diagnosed with pancreatic cancer is alive at 5 years, reflecting late diagnosis and poor prognosis even with resection.
Certain diseases, including chronic pancreatitis, diabetes mellitus, and hereditary cancer syndromes, predispose toward pancreatic cancer. The pain from pancreatic cancer is located in the epigastrium and has a quality characterized as deep and boring. Dual-phase CT helps determine surgical resectability through assessment of invasion of major vessels. Therefore, clinical utility of CA19-9 lies more with monitoring response to therapy, prognostication and surveillance for recurrence after treatment. Proponents of routine biopsy have cited the rare possibility of detecting a chemosensitive tumor (lymphoma) and the desire of many patients to know their diagnosis before major surgery. Because the only chance of cure is through resection, all patients with potentially resectable lesions by CT criteria should be referred for surgical consultation. The AGA guidelines have stressed the importance of cardiac, pulmonary, and nutritional optimization before pancreatic surgery. Studies have now established that surgical adjuvant chemotherapy leads to modest mortality benefit especially in patients with negative resection margins after surgery.
EUS-guided celiac nerve neurolysis can offer significant pain control and decrease narcotic requirements. Nuclear imaging after administration of radiolabeled octreotide aids in localizing some neuroendocrine tumors. Small (<1 cm), simple, asymptomatic cysts discovered incidentally may be observed using follow-up imaging. The ERCP features of IPMN include a gaping papilla, with the extrusion of mucin, and global or segmental main duct or side branch dilation, with papillary projections (Figure 5). Blow the whistle, expose the elder neglect, file an administrative report with the hospital and file a decubitus ulcer lawsuit with a decubitus ulcer lawyer.
This is associated with inability of the pancreas to secrete enough insulin to overcome the defect. Complications are usually present at diagnosis of diabetes (microvascular diabetic complications are present in up to 20% of patients when first diagnosed with T2DM). However, the OGTT is more costly, inconvenient and time-consuming than the FPG, and the repeat test reproducibility is worse.
When following up these patients, the FPG should be the first test used, as it will avoid the more time consuming OGTT should the patient’s FPG level be diagnostic for diabetes. Management The major aim of diabetes management is to prevent diabetesrelated complications, both microvascular (retinopathy, nephropathy, neuropathy) and macrovascular (stroke, ischaemic heart disease, peripheral vascular disease). An unfortunate side effect of acarbose is the high incidence of gastrointestinal symptoms and bloating. 19 If glycaemic control remains suboptimal, the regimen will need to be changed to twice daily insulin injections of either a long-acting or a pre-mixed insulin preparation (containing fixed proportions of short-acting and long-acting insulin, e.g.
Patients with hereditary pancreatitis develop acute recurrent pancreatitis in childhood, which usually progresses to chronic pancreatitis and pancreatic cancer in early adulthood. Severe abdominal pain suggests neural plexus involvement, location in the tail, unresectability, and a poor prognosis.
Preoperative endoscopic biliary drainage is not recommended except for cases of cholangitis or symptomatic obstructive jaundice. Diarrhea and weight loss from maldigestion may be palliated through the use of pancreatic enzymes. Most NETs are listed in the differential diagnosis for secretory diarrhea, although the yield of testing in this setting is extremely low. Insulinomas are not well visualized with octreotide scans because they do not possess high concentrations of somatostatin receptors.
A history of past acute pancreatitis or imaging criteria suggesting chronic pancreatitis should increase suspicion of a pseudocyst. Debridements and plastic surgery are possible treatment solutions for Stage 4 decubitus ulcers. Lifestyle interventions are likely to reduce cardiovascular disease and total mortality, while drugs which reduce insulin resistance, such as metformin or the thiazolidenediones, may help.
Patients with previously sedentary lifestyles should start with a shorter duration of low- to moderate-intensity activity, gradually increasing to the set goal.
Glibenclamide has a very long half-life, owing to formation of active metabolites that are usually excreted by the kidney, and so should not be used in patients with renal impairment or the elderly due to the risk of protracted severe hypoglycaemia. Family history is another important risk factor where the degree of risk correlates with the number of family members affected by the disease. Painless jaundice indicates a potentially resectable lesion located in the pancreatic head. Patients with biliary obstruction might require surgical or endoscopic biliary decompression.
Nonfunctional tumors are most often indolent but can demonstrate malignant behavior, including metastases. Significant data have been published over the years that led to development of consensus guidelines.4 In this guideline, obstructive jaundice from the cyst, dilation of main pancreatic duct (MPD) more than 10mm not attributable to mucus, stone or CP and enhancing solid components within the cyst are identified as indications for resection.
The United Kingdom Prospective Diabetes Study, the largest and longest prospective randomised trial in people with T2DM, showed that a reduction in HbA1c by just 1 percentage point reduced the risk of microvascular disease by an average of 37%. The exercise prescription may need to take the form of non-weight bearing exercise such as swimming or resistive exercises with free-weights in people with chronic disability who are unable to bear weight for long periods. The sulfonylureas have roughly the same effect on lowering HbA1c as other oral antihyperglycaemic agents (about 1.5 percentage points), but usually lose their effectiveness over time due to the natural history of progressive insulin deficiency in T2DM. This is a different condition to T1DM or the previously used description, insulin-dependent diabetes mellitus. Patients with a significant familial risk (>2 first-degree relatives, multiple second-degree relatives, early onset of pancreatic cancer before age 50 years) may be an appropriate target population to do surveillance endoscopic ultrasound (EUS).
The AGA guidelines have recommended preoperative biliary stenting for jaundiced patients in whom surgery will be delayed for several weeks or in patients with unresectable tumors.
Gastric outlet obstruction can be managed by surgical gastrojejunostomy or endoscopic stenting.
Speak with a decubitus ulcer lawyer to obtain relevant legal advice specific to your potential case. 13 T2DM is usually part of the metabolic syndrome, so it is important to treat comorbidities in patients with T2DM, particularly hypertension, dyslipidaemia, smoking and obesity. The hiring of a lawyer is an important decision that should not be based solely upon advertisements.
The United Kingdom Prospective Diabetes Study demonstrated that aggressive control of blood pressure lowered the incidence of diabetic complications by 24%.
Many patients have impaired gastric motility as a result of the local invasion of nerve fibers. 14 This was true for both microvascular and macrovascular disease and was even more marked than the effect of intensive blood glucose control. The importance and effectiveness of the multifactorial approach in treating T2DM was studied recently with a stepwise implementation of behaviour modification and drug therapy that targeted hyperglycaemia, hypertension, dyslipidaemia, and microalbuminuria. 15 The study suggested that the greatest benefits in preventing cardiovascular disease are seen when glucose, blood pressure and lipid levels are targeted simultaneously.
