Introduction and objective: Diabetic foot is the result of uncontrolled diabetes and imperfect sanitary care which leads to necrotic lesions, gangrene and finally amputation. Materials and methods: The study population included 120 consecutive diabetic patients who were hospitalized in the department of vascular surgery due to diabetic foot during 2006-2008. Conclusion: This study shows that fungal infection can be observed in about more than 20% of diabetic foot and causes a lesion with poor prognosis. Neuropathy leads to an insensitive and sometimes deformed foot, often with abnormal walking pattern.
Bacterial infection of diabetic foot ulcers are polymicrobial and have aerobic and anaerobic origin, which have been characterized in detail [11,12]. During the 33 months period, from January 2006 to September 2008, 120 consecutive diabetic patients (86 male, 34 female) with chronic diabetic foot ulcers whose wounds have not already received any antiseptic, antibiotic or surgical treatment were examined for fungal infection. Scraping of the lesion surface and nail clipping was performed for all feet with diabetic ulcers.
The colonies were identified on the basis of their macroscopic and microscopic (slide culture) features.
Of these, direct examinations in 10% KOH were positive for fungal elements in 25(20.8%) cases, but cultures were positive in 30(25%) cases.
Similar to previous investigations [6, 13], significant relationships were found between gender and age of the patients. We conclude that fungal infection can be observed in more than 20% of patients with diabetic foot ulcers, and Candida spp.

Vitrectomy is useful for vitreous haemorrhage and late complications of proliferative retinopathy.
The management of diabetic retinopathy (DR) depends on accurately recognising or classifying the different types of DR and knowing what treatment to give the patient. DR has clinical signs which can be seen with an ophthalmoscope or with a slit lamp and a 90- or 78-dioptre lens. The new vessels damage sight by bleeding (Figure 5) or forming sheets of fibrovascular membranes that may cause traction retinal detachments. The early treatment of diabetic retinopathy study (ETDRS) defined clinically significant macular oedema (CSMO)1 as the stage at which the eye needs to be treated in order to prevent loss of vision. The blood vessels in the central part of the retina may also become blocked (capillary closure), leading to macular ischaemia.
The two main treatment options for proliferative DR are pan-retinal laser photocoagulation and diabetic vitrectomy. Pan-retinal photocoagulation (PRP), or scatter laser, is the main form of treatment for proliferative diabetic retinopathy.
The aim of the laser is to induce regression of new blood vessels (that is, to make them stop growing and shrink). The technique is an important part of the treatment of proliferative diabetic retinopathy and leads to improvement or stabilisation of vision in 90% of patients.1 2 Vitreous and blood are cut and aspirated and membranes causing tractional detachment of the retina are removed. In countries without screening, many people present with long-standing tractional retinal detachments of the macula. In a proportion of patients, intravitreal bevacizumab preoperatively may lead to clearing of the vitreous haemorrhage, thus avoiding surgery. In the Diabetic Retinopathy Clinical Research Network trial, intravitreal injections of the steroid triamcinolone acetonide was compared with standard laser treatment. Anti-vascular endothelial growth factor (anti-VEGF) treatment VEGF levels are increased in the vitreous and retina in patients with diabetic retinopathy. In practice, laser should remain the cornerstone of treating clinically significant macular oedema and the use of intravitreal injections should be tailored to the needs of individual patients.
Treat circinate exudates (Figure 6) with focal laser, blanching the retina in the centre of the exudate.
Start with a low power setting, around 150 milliwatt, and increase the power until the desired endpoint is reached. In patients with established foveal thickening or who are not responding to laser, consider intravitreal bevacizumab.
We audited a number of patients who had ultimately needed vitrectomy for advanced proliferative disease to find out how we could improve, and arrived at the following recommendations for laser in countries where patients may not come for regular appointments. Warn all diabetes patients to come if they experience floaters or blur, as these symptoms suggest a vitreous haemorrhage.
Give PRP to anyone who has vitreous or sub-hyaloid blood (Figure 5) even if there are no visible new vessels. Diabetic retinopathy (DR) can be diagnosed by clinical examination alone if you are good at examining the retina with a slit lamp microscope. Fluorescein angiography is a technique for examining the fine detail of the retinal circulation. Optical coherence tomography (OCT) is a relatively new technique that uses lasers to scan the retina and build up a very detailed three-dimensional image. Diabetes blood sugar levels chart: what is a normal blood, Keep in mind that the blood glucose level before a meal for a non diabetic person and a person with prediabetes may be very similar. When your “normal” blood sugar isn’t normal (part 1), In the next two articles we’re going to discuss the concept of “normal” blood sugar. Blood glucose levels : testing and normal range, A blood glucose test measures the amount of a type of sugar, called glucose, in your blood.

As the number of patients with type 2 diabetes reaches epidemic proportions worldwide a€“ and is expected to double during the next 20 years a€“ researchers are working to gain a basic understanding of the molecular relationships between diabetes and heart disease to identify new drug targets. Using cutting-edge physiological, molecular and proteomic approaches, the team closely examined a key signaling pathway called mammalian target of rapamycin (mTOR). In 2006, in a study published in the Journal of Molecular and Cellular Cardiology, the team reported a protective role of rapamycin against heart disease in a non-diabetic animal model.
According to Das and Kukreja, further research is needed to understand the molecular mechanisms underlying metabolic and heart function benefits of rapamycin in patients with diabetes.
Scientists at Dana-Farber Cancer Institute have discovered why diabetic-like symptoms develop in some patients given rapamycin, an immune-suppressant drug that also has shown anti-cancer activity and may even slow ageing. Having diabetes doubles a person's risk of dying after a heart attack, but the reason for the increased risk is not clear. Elderly mice suffering from age-related heart disease saw a significant improvement in cardiac function after being treated with the FDA-approved drug rapamycin for just three months. Too much sugar can set people down a pathway to heart failure, according to a study led by researchers at The University of Texas Health Science Center at Houston (UTHealth). All's not fair in love and glucose intolerance - overweight men are more prone to get type 2 diabetes than are overweight women. Mitochondria are the engines that drive cellular life, but these complex machines are vulnerable to a wide range of breakdowns, and hundreds of their component parts remain a functional mystery.


Health experts have long believed that sickle cell gene variants, which occur in about 1 in 13 African-Americans, increase the risk of premature death, even when people carry only a single copy of the variant. A handful of large studies of cancer risk factors have found that working the night shift, as nearly 15 percent of Americans do, boosts the chances of developing cancer.
In their mission to design new biomaterials that promote tissue regeneration, Drexel University researchers have identified how inflammation, when precisely controlled, is crucial to bone repair. The most common cause of mycotic diabetic foot is different species of Candida spp., especially C.
Worldwide, over~246 million people suffer from the disease in 2007 and estimates for 2025 are depicted at a total of 380 million patients [1]. In patient with neuropathy, minor trauma-cased for example by ill-fitting shoes, walking barefoot, or an acute injury- can precipitate a chronic ulcer [2,3]. However, little data are available on the prevalence of fungal foot infections in patients with diabetes [6,7]. However, data on the frequency of fungal isolation from the diabetic patients are rare and heterogeneous.
1, 2) that they did not use antifungal agents in the last four weeks before fungal examinations were studied. A portion of the material was soaked in 10% KOH and analyzed by direct microscopic mycological examination and the rest was cultured on Sabouraud dextrose agar (SDA, Biomark, Himedia, India) and SDA supplemented with chloramphenicol (SC) and SC medium with cycloheximide (SCC), (Quelab, Canada). Yeast samples were cultured in Chrom agar Candida (Himedia, India) and Cornmeal agar (Himedia, India) with Tween 80 for isolation and identification of Candida spp. Foot ulcers were found in 108 patients (90%), and previous toe amputation in 20(16.7%) of patients. Five cases of direct microscopies were negative but their cultures were positive for Candida species.
The risk of toe or lower leg amputation may be increased if ulceration is followed by bacterial and fungal infections [6,9,10]. Our data are supplemented by the results of questionnaire containing demographic and clinical information of the patients. Majority of the patients with diabetic foot ulcers were men and older than 40 years and all of the fungal infections were found in men, older than 50 years of age (17 patients older than 60 years and 13 patients older than 50 years).

There are clinical signs which can be seen with an ophthalmoscope or a slit lamp and 90- or 78-dioptre lens. Treatment usually maintains vision, but does not restore vision that has already been lost. The commonest error is undertreatment, and laser should be applied until there is regression of the new vessels or there is no room for further treatment.
The advantage of the slit lamp is that it allows you to visualise the retina with both eyes. However, the key characteristic of proliferative DR is new vessels growing onto the posterior vitreous surface from the retina or optic disc (Figure 4).
Traction retinal detachment occurs when the fibrovascular tissue contracts and pulls the retina away from the underlying choroid. I hail from a remote rural village in Prakasham District and I joined the vision technician programme at LVPEI in 2007. I also record any history of blurred vision for distance or near vision, flashes, floaters in the field of view, and any fluctuations in vision.
During a slit lamp examination (before dilation) I look mainly for neovascularisation of the iris and record intraocular pressure. Eye care workers would do well to check their patients’ blood pressure and advise those with high blood pressure on the importance of control, referring them to a physician if they needed help. So, for practical clinical purposes, look for other easily visible markers for macular oedema such as exudates within a disk diameter of the fovea.
It must be given early enough and cover enough retina to induce regression of the vessels that cause the complications of vitreous haemorrhage and tractional detachment of the retina. Treatment includes steroids, anti-vascular endothelial growth factor (anti-VEGF), and laser.
Although there were short-term improvements in visual acuity with intravitreal triamcinolone acetonide (IVTA), this improvement was not sustained. The most recent anti-VEGF drugs to be evaluated in the treatment of diabetic maculopathy are ranibizumab2 (Lucentis) and bevacizumab5 (Avastin).
There was a 50% reduction in moderate visual loss in the group that received laser (from 24% to 12%).
Burns should be one burn width apart, using a spot size of 75 to 125 microns, duration 20–50 milliseconds.
It is wise to avoid treating perifoveal microaneurysms as this is likely to increase perifoveal capillary dropout (consider intravitreal bevacizumab instead).
The treatment plan followed the textbook recommendation of doing focal laser for the maculopathy first. Using the slit lamp, you will be able to detect haemorrhages, new vessels, exudates, and retinal thickening due to oedema.
The cost of fundus cameras is still high, but they are becoming more affordable and the quality of pictures is improving all the time. It will show the leaks that cause exudative maculopathy and the areas of blocked capillaries that cause ischaemic maculopathy and proliferative retinopathy. This will not only detect any oedema or swelling of the retina, but also measure it and draw a map that shows the areas where the swelling is greatest.

Diabetes is associated with heart attack, and patients with elevated fasting glucose are at a three-fold increased risk of mortality following a heart attack.
14in the Journal of Biological Chemistry, researchers report that rapamycin, an antibiotic used to boost organ survival in transplant patients, may protect the heart against complications associated with type 2 diabetes in an animal model.
It is a signaling pathway responsible for the regulation of cell growth and metabolism, and has been implicated in a number of human diseases, including diabetes. The team has plans for new studies in translational animal models of type 2 diabetes to show that rapamycin can minimize damage to the heart after an acute heart attack. This study was designed to investigate the incidence of fungal pathogens in diabetic foot infections. Direct examinations in 10% KOH were positive for fungal element in 25(20.8%) cases, but cultures were positive in 30(25%) cases.
Other possible causes of this increased prevalence of infections are defects in immunity, peripheral vascular disease and slower wound healing [4].
Some studies have reported that some filamentous fungi and yeasts as etiological agents of diabetic foot infection [6,9,13-21]. They were initially presenting with diabetic foot ulcers to the university department of vascular surgery in Emam Reza hospital, Mashhad University of Medical Sciences, Mashhad, Iran.
Direct microscopy and culture of all of the the filamentous fungi were positive for fungal elements, and in 90(75%) cases, culture and direct microscopy were negative (Table 2).
It has already been suggested that fungal infections may be involved in the pathogenesis of diabetic foot ulcers, but this needs more investigation [4]. This stereoscopic vision provides a sense of depth which aids diagnosis, particularly of macular oedema. During this programme, we were trained to look for diabetic retinopathy (DR) by direct ophthalmoscope. If the media are not clear or if the patient has signs of DR, I will refer the patient to a secondary centre ophthalmologist for dilated fundus examination, which will give them the information they need to manage the patient’s DR. The optimum time for a preoperative injection would seem to be 5–7 days before the operation. These trials showed a benefit with intravitreal ranibizumab and bevacizumab in patients with foveal thickening. The chorioretinal atrophy caused by burns, especially intense burns, within 300 to 500 microns of the fovea can years later extend into the fovea and cause vision loss, particularly in myopes. In the interim, every residency programme must provide training in the skills needed to manage DR, including interpreting investigations and delivering laser and other treatments.
The patient then missed two appointments and pan-retinal photocoagulation (PRP) was delayed by about two months.
This is particularly important if there are large neovascular (NV) formations which have an increased risk of bleeding, or if the patient is unlikely to return. However, injections of fluorescein carry a small risk (about 1:20,000) of a severe allergic response, which can be fatal. Diabetic foot disease is a poly etiological disease, in the majority of patient peripheral neuropathy plays a central role.
Investing in a diabetic foot can be one of the most cost-effective forms of healthcare expenditure [8]. Most of the patients (75%) have severe disease and have been hospitalized however 25% of them were in general practice. Majority of the patients with skin lesions had uncontrolled diabetes, because uncontrolled diabetes increase the risk of development of microangiopathy and related complications or sequelae.
We believe our results have important implications for the prevention and recognition of mycotic foot disease in diabetic foot and recommend that diabetic foot patients should be examined for fungal infections.
Other aids to DR diagnosis are fundus photography, fluorescein angiography, and optical coherence tomography (see box on page 7). However, intravitreal ranibizumab injections cost around US $1,200 each and the patients in this study received eight or nine injections in the first year (a cost of around US $10,000 per patient per year.) Intravitreal bevacizumab is much cheaper.
Refresher courses can be arranged for those not adequately trained or who have been without the necessary equipment for some time. When PRP was finally given, the intention was to give it in the recommended multiple sessions.
If patients come from far away, consider admitting them to complete the laser before they are discharged.
If bleeding occurs after laser, re-treat until NV formations have gone or maximal treatment has been given. The most valuable use of photography is in patients with diabetic maculopathy or new vessels who have laser treatment. This indicates that gender-related factors affect the skin and nail structure and it may be due to differences in life style, propensity to micro traumatisms, professi-onal activities, sport practices and etc. This helps me to identify patients with DR, who I would then send to a secondary centre for further management.
We are able to offer patients an intravitreal bevacizumab injection for as little as US $25.
We must also advocate for lasers and other necessary equipment wherever there is a trained ophthalmologist. However, due to further missed appointments, the interval between laser sessions was over a month.
A pan-retinal pattern of excessively intense burns can lead to choroidal effusion and angle-closure glaucoma with blindness. In high-income countries, OCT and photos, in combination, are the usual means of documenting and investigating DR. The isolated opportunistic molds were known as Acremonium spp., Aspergillus fumigatus and Scopulariopsis spp. The objective of this study was to determine the etiologic agents and frequency of fungal infections in ulcerated diabetic foot tissue samples by conventional mycological technique. This conflicting data can be explained by differences in exposure time to infection agents and differences in climatic and socio-economic factors in the respective geographical areas. As cameras and OCT machines become more affordable, they will also become more widely used in low- and middle income countries. If you only examine the patient occasionally, it is difficult to remember exactly what the retina looked like before you treated it. By then, tractional retinal detachment involving the macula had developed and vitrectomy was required. When you can still see retinopathy months after laser treatment, you may be unsure if it is better, worse, or much the same. Honestly, it was very difficult to differentiate fungal infection from fungal colonization. To avoid this problem sampling was performed by scalpel rather than swab and the samples were cultured on serial passages.
