Diabetic foot ulcer is a common complication in diabetic patients and the outcome of foot ulcer depends on the severity of ulcer and combined infection such as osteomyelitis. So antibiotics targeting Gram positive cocci including Staphylococcus aureus have been used frequently. However, during the antibiotic therapy, diverse adverse reactions could be happened including red man syndrome, chest pain, hypotension, thrombocytopenia, neutropenia and drug eruption. Among these reactions, hematologic adverse events such as pancytopenia are rare and it could be lethal if happened. This article reports a case of pancytopenia associated with vancomycin in treating the diabetic patient with infected foot ulcer.

BACKGROUND Foot ulcer diseases are more prevalent in diabetic patients than that those of non-diabetic patients. Several reports showed the risk of amputation and the medical cost were increased when foot ulcer developed. Therefore, strict glycemic control from the initial period of diabetes is necessary. Since there is no enough epidemiologic data, large scaled studies for medical and economic consequences about diabetic foot ulcer are needed. METHODS: This study was based on health insurance claims submitted to the National Health Insurance Review Agency during the period from December 1994 through December 2002. We investigated the incidence and medical cost of foot disorders in Korean population using the disease-classification codes on the health insurance claim forms. RESULTS: The incidences of foot disorders (per 100,000 of population) were 49.7 for amputations, 99.7 for ulcers, and 1,051 for injuries in diabetic patients, and 4.2 for amputations, 10.3 for ulcers, and 943 for injuries in non-diabetic patients. Relative risk of the incidences of foot amputation, ulcer, and injury in diabetic patients comparing with non-diabetic patients were 11.7, 9.7, and 1.1, respectively. Total medical costs (per capita) of foot amputation, ulcer, and injury in diabetic patients were 2.0, 1.7, and 2.1 times higher, respectively, than those of non-diabetic patients. Mean hospital stay of foot amputation, ulcer, and injury in diabetic patients were 1.6, 1.3, and 1.7 times more, respectively, than those of non-diabetic patients. CONCLUSION: In diabetic patients, the incidences of foot amputation and ulcer are higher than those of non-diabetic patients. To reduce those incidences, we need to early strict glycemic control as well as government based management.

BACKGROUND The purpose of this study was to determine the prevalence of fungal infection and ulcer on the feet of diabetic patients and the existence of correlation between ulcer and fungal infection. METHODS: A total of 21,693 outpatients diagnosed as diabetes mellitus at the department of endocrinology of 32 hospitals were examined. The diabetic patients with foot problems were consulted to the department of dermatology. Physical examination and KOH preparation were performed by a dermatologist. RESULTS: 13,271 patients had certain kinds of foot problem, accounting for 61.2% of 21,693 diabetics examined. Of these, fungal foot disease was found in 10,403 patients that constituted 78.4%(48.0% of the entire diabetic population). Tinea pedis was the diagnosis in 6,496(29.9%), onychomycosis in 7,783(35.9%), and coexistence was in 3,883(17.9%). Foot deformity was in 1,346(6.2% of diabetics; 10.1% of foot disease), nonpalpable pulse in 1,051 (4.8%; 7.9%), and foot ulcer was in 425(2.0%; 3.2%), following in a descending order of frequency. Odds ratios for diabetic foot ulcer were 2.5 in patients with the foot deformity, 1.6 with fungal foot disease and 2.2 with non-palpable pulse. Conversely, odds ratios for fungal foot disease were 2.5 with foot deformity, and 1.6 with foot ulcer. A total of 5,486 patients paid visit to the department of dermatology. Of these, 4,519 patient were diagnosed with fungal infection through physical examination and KOH smear by dermatologists. The population were comprised of 2,272 males and 2,247 females, showing similar prevalences between sexes. However, age did have positive correlation regarding prevalence of fungal foot disease. The number of diabetic patients with toenail problems was 3,847(70%) and onychomycosis was proven mycologically in 3,276 patients. Onychomycosis of distal subungal type was the most common clinical finding, most frequently involving the great toenails. Abnormal skin findings of the foot were seen in 3,885 (70.8%) and tinea pedis was found in 3,209(58.5%), most commonly involving the soles. CONCLUSION: This study showed that fungal infection might be regarded as a risk factor of foot ulcer. Treatment of fungal infection in diabetic patients might prevent diabetic foot disease such as ulcer and reduce the disability, morbidity and mortality in diabetic patients.

BACKGROUND Foot ulcers are a common complication of diabetes mellitus, and their prevalence is increased relative to those without diabetes. Foot ulcers and related complications represent an important cause of morbidity among patients with diabetes mellitus. Most of the poor prognosis factors and amputation risk factors of diabetic foot ulcers have been found to be largely affected by male sex, inadequate blood glucose control, vascular disease, neuropathy, end organ defects, and the depth and size of ulcers, prior ulcer history, infection and ischemia. Currently, the poor prognosis factors and amputation risk factors of diabetic foot ulcers in the Korean diabetic population are unknown. The purpose of this study was to identify and quantify the poor prognosis factors of diabetic foot ulcers and the risk factors of lower extremity amputation. METHODS: This study comprised of involved 37 male and 14 female diabetics with foot ulcers aged 23 to 83 years. According to the results of treatment, the patients were divided into 4 groups; complete healing (CH), partial healing (PH), unhealing (UH), and amputation (AM) groups. The baseline characteristics of the study subjects (gender, age, duration of diabetes, BMI, drinking, smoking, insulin therapy, blood pressure, whole blood count, renal function test and the size and depth of ulcer, prior ulcer history, osteomyelitis, infection, ischemia, neuropathy and retinopathy) were examined. RESULTS: The following characteristics were not significantly related to the poor prognosis factors and amputation risk factors of diabetic foot ulcers: age, duration of diabetes, BMI; drinking, smoking, insulin therapy, blood pressure, whole blood count and renal function test. The following characteristics were significantly related to the poor prognosis factors and amputation risk factors of diabetic foot ulcers: male (p=0.021), ischemia (p<0.05), infection (p<0.01), osteomyelitis (p<0.01), prior ulcer history (p<0.05), retinopathy (p<0.05), size of ulcer (p<0.001) and depth of ulcer (p<0.001). The size and depth of an ulcer, prior ulcer history, ischemia and infection were found to be associated with poor prognosis factors of treatment and risk factors of amputation in diabetic foot ulcer patients by a multiple regression test (P<0.05). CONCLUSION: This study shows that the size and depth of an ulcer, prior ulcer history, ischemia and infection are poor prognosis factors of diabetic foot ulcer and amputation risk factors However, further studies will be required due to the smaill size of our study population.
BACKGROUND Foot ulcers, and lower-extremity amputations, are relatively common complications of diabetes mellitus and their clinical management is very important. High plantar pressure is known to be a major risk factor of foot ulceration in diabetic patients. The EMED-system is used for the assessment of pressure distribution for the identification of focal areas at high risk of ulceration that merit protection from preventive footwear. However, a potential relationship between diabetic neuropathy and the plantar pressure has not been fully evaluated. Changes in the plantar pressure were measured in diabetic patients, both with and without peripheral polyneuropathy, using the EMED - AT system to clarify if diabetic neuropathy increases the plantar pressure. METHODS: Ninety seven patients with type 2 diabetes were divided into two groups on the basis of their peripheral polyneuropathy. No patient had a past history of foot ulceration. The clinical characteristics of 2 groups were analyzed, and their plantar pressures was measured using the EMED - AT system. These results were analyzed, with the EMED software program, after their division into ten masks for a so-called "regional analysis". The pressure time (PTI) and force- time (FTI) integrals were analyzed for each mask on both feet. RESULTS: The diabetic neuropathy (DN) group showed significantly higher FTI levels in both masks 05 (area of the 1st metatarsal head) and masks 08 (area of the hallux) than the diabetic control (DC) group. The PTI was also higher in right the mask 08 of the DN group than in the DC group. CONCLUSION: These results suggest that peripheral neuropathy to be an important risk factor, and predictor of diabetic foot ulcers, due to the increasing plantar pressure in some areas of the foot. Measurement of the plantar pressure may be a useful method for the diagnosis and monitoring of foot disorders in diabetic patients with peripheral neuropathy.
BACKGROUND Diabetic patients with non-infected neuropathic foot lesions frequently have prominent pedal arteries and distended dorsal foot veins, both in the ulcerated and in the non-ulcerated foot. Such patients also have increased blood flow in the lower limbs as suggested by plethysmographic and ultrasound studies. Accordingly, the aim of this study was to evaluate the venous oxygenation, as determined by partial pressure of oxygen(PO), in the feet of diabetics with and without foot ulceration and neuropathy in order to confirm the arteriovenous(A-V) shunting in the diabetic neuropathic foot may be important in the pathogenesis of ulceration. METHODS: Venous PO was measured in the feet and hands of four subject groups: 8 diabetics with neuropathy and foot ulceration(group 1); 10 diabetics with neuropathy but no ulceration(group 2); 10 diabetics with no evidence of neuropathy(group 3); and 9 non-diabetic controls(group 4). After an initial 30-min period of stabilization, veins on the dorsum of each foot and on the back of the hand were cannulated using a Butterly infusion set, 0.8mm gauge. Blood was withdrawn from each site into a heparinized glass syringe for immediate analysis of PO using a blood gas analyser. RESULTS: The mean venous PO2 in the feet of diabetic subjects with neuropathy and foot ulceration (group 1: 60.7+6.3mmHg)was significantly higher than in controls(group 4: 44.3+6.0mmHg) or the other two diabetic groups(group 2: 52.3+9.0mmHg, group 3: 46.1+5.5mmHg). Venous PO2 in the feet of the diabetic subjects with ulcers was also significantly higher than in their hands(45.4+5.8mmHg) or in the hands of the other groups(group 2:.46.6+6.3mmHg, group 3: 44.5+4.9mmHg, group 4: 44.9+5.1mmHg). CONCLUSION: These results provide further evidence of abnormal blood flow in the diabetic neuropathic foot and are compatible with arteriovenous shunting.
