Toe amputations are becoming more prevalent in the diabetic population. To prevent toe amputations, those individuals with the highest risk must be identified prior to developing a precipitating event. There are obvious risk factors for toe amputations, such as digital deformity, diabetic neuropathy, and ischemia. Other, less obvious, systemic comorbidities may be linked to toe amputations. This study also shows that gender plays a significant role as a risk factor for toe amputation. A foot infection, foot abscess, osteomyelitis, diabetic retinopathy, and diabetic nephropathy were also significant risk factors for toe amputations. This suggests a significant relationship between these complications and comorbidities that put these individuals at a higher risk for toe amputations.

Tuberculous osteomyelitis of sternum after open heart surgery is a rare disease entity. We report a case of wound infection with osteomyelitis caused by Mycobacterium tuberculosis in a patient with diabetic nephropathy, requiring peritoneal dialysis after coronary artery bypass grafting, who was successfully treated with antituberculous agents and surgical debridement. In addition, we provide a literature review on reported cases of tuberculous sternal osteomyelitis and mediastinitis after open heart surgery, and discuss about the risk factors, clinical features, and treatment of this infection.

IgA immune complex deposition is not commonly seen with acute postinfectious glomerulonephritis secondary to staphylococcal infections. Its deposition is usually indicative of IgA nephropathy or Henoch-Schonlein purpura nephritis. We describe a patient with a history of diabetes mellitus who was admitted with methicillin resistant Staphylococcus aureus bacteremia and subsequent demonstration on renal biopsy of crescentic glomerulonephritis associated with codominant IgA and C3 immune deposits and early changes of diabetic nephropathy. After aggressive treatment of infection, which included bilateral metatarsal amputation and subsequent left below-the-knee amputation as well as antibiotic administration for persistent osteomyelitis, the patient's renal function progressively improved with a reduction in serum creatinine concentration from 6.1 mg/dL (539 micromol/L) to 2.7 mg/dL (239 micromol/L). On a 3-year follow-up evaluation, his serum creatinine concentration was 1.7 mg/dL (150 micromol/L) and urine was negative for protein and blood.

The aim of our study was to analyse the foot infections in diabetic patients. We analysed foot ulcerations in 124 diabetics who attended outpatient foot clinic, or were hospitalized in the period from 1996 to 2006. Basic neuropathy screening examination was made with cotton wisp, pin-prick, tuning fork, and monofilament. For evaluation of leg ischemia, besides the evaluation of the presence of pedal pulses, the ankle-brachial pressure index was measured. If the infection of foot ulceration was clinically present, bacteriology examinations was performed. In the case of deep wound infection, x-ray examination was made. If bone destruction was present, osteomyelitis was diagnosed by technecium bone scanning and by technecium-labelled leukocyte scan. Deformation and destruction of the bone without infection was appoited as Charcot neuroarthropathy. Foot ulcer infection was found in 58 % diabetic patients, wounds were more often deep (80 %). Infection was not associated with special location of foot ulcer. Two-third of the total infected wounds were associated with leg ischemia and 30.6 % of infected ulcer ended with leg amputation. More foot ulcer infections were found in the diabetics with HbAlc over 8 %. Infection was coupled with diabetic retinopathy (in 63 % patients) (p=0.023), and also with diabetic nephropathy (in 66 % patients) (p=0.012). Bacteriology examination revealed most often Staphylococci (45.8 %), antibiotic therapy was made most often with chinolones. Osteomyelitis was present in 34.7 % of foot ulcer infections. In 14 diabetics (56 %) after antibiotic therapy it was not necessary to perform a leg amputation. HbAlc seems to be a significant predictor of osteomyelitis (p<0.02; OR=1.76). In conclusion, we confirmed that diabetic foot infections, especially on ischemic leg, in diabetics with poor metabolic control and chronic diabetic microvascular complications, are associated with a higher risk of leg amputations. Further, it is possible to cure osteomyelitis successfully without surgery in more than half the cases (Tab. 1, Ref. 24). Full Text in free PDF www.bmj.sk.

Bacteremia from central venous catheter (CVC) infection causes morbidity and mortality in patients on hemodialysis (HD). Diagnosis of the infection can be difficult and may require special imaging. A 70-year-old man with diabetic nephropathy was on HD for 11 months through a permanent CVC. Because of symptomatic osteoporosis, he had kyphoplasty in three lumbar vertebrae (L2, L3, L4) 6 months after starting HD. Severe back pain persisted after kyphoplasty. Throughout the HD period, the exit site of the CVC had a clean appearance, there was no fever, and blood leukocyte counts were normal. During the 11th month of HD, he complained of subjective fever at home. Blood count revealed normal leukocyte count with neutrophilic predominance and blood cultures grew methicillin-resistant Staphylococcus aureus (MRSA). Echocardiogram revealed no heart valve vegetations, but irregular thickening of the CVC wall. Fluorodeoxyglucose positron-emission tomography-computed tomography (FDG-PET-CT) revealed severe inflammation of the CVC wall and a picture consistent with osteomyelitis and severe destruction of the body of the 11th thoracic vertebra. He was treated with intravenous vancomycin and removal of the CVC, the wall of which was grossly inflamed and grew in culture MRSA. Three weeks later, he discontinued HD because of persistent severe back pain. CVC infection with bacteremia and remote infectious foci having grave sequelae can develop in HD patients with paucity of clinical manifestations. FDG-PET-CT is a useful imaging tool in establishing the presence and extent of both the CVC infection and remote metastatic infectious foci.

In the same manner as syphilis, tuberculosis (TB) was often called "The Great Imitator". We have to consider not only malignancies but also TB as a differential diagnosis when we find any tumorous regions. We report herein on a rare case, clavicular osteomyelitis due to TB. A 72-year-old female, with diabetic nephropathy, was on maintenance hemodialysis. She had a fall 2 months prior to admission followed by pain around her right clavicle. Ulceration occurred in that region a month prior to admission, and CT scan revealed a fracture of the right clavicle with a tumor surrounding that area. Seven days prior to admission, she went to a neurologist because of dizziness. MRI of the brain revealed a tumor in her pons. The physician suspected the tumor was metastasis. Needle biopsies revealed only necrotic tissue so the medical oncologist consulted us because they suspected it was caused by infection of some kind. From the patient's history and the physical examination, we suspected TB osteomyelitis and grew some more cultures, but only MRSA and E. coli were detected. We administered vancomycin and cefmetazole for the secondary bacterial osteomyelitis. After a month of hospitalization, we found miliary regions on her chest CT and Mycobacterium tuberculosis was grown from the needle biopsy specimen. We started multi-antituberculosis therapy and the patient had a good prognosis. We report herein on a rare case of clavicular osteomyelitis due to TB, together with a review of the literature.
