Necrotizing cellulitis and fasciitis may be difficult to recognize. When skin necrosis is not obvious, the diagnosis must be suspected if there are signs of severe sepsis (accelerated heart or respiratory rates, oliguria, mental confusion.) and/or some of the following local symptoms or signs: severe spontaneous pain, indurated edema, bullae, cyanosis, skin pallor, absence of lymphangitis, skin hypoesthesia, crepitation, muscle weakness, foul smell of exudates. Many risk factors are suspected. A recent case-control study demonstrated that using ibuprofen increased the risk of cellulitis complicating chickenpox in children. Evidence is lower for other risk factors that are present with a high prevalence in most series: local lesion of skin or mucous membranes (acute or chronic disease, traumatism, surgery.), diabetes, arteriopathy, alcoholism, obesity, immunosuppression, NSAIDs. The risk of streptococcal necrotizing fasciitis is increased when in contact with patients infected by the same streptococcus.

A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU, ALT 41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve. Disseminated intravascular coagulation syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.

We studied the features of acute renal failure (ARF) in elderly patients treated in a hospital, without an intensive care unit, to identify etiological factors and establish adequate preventive measures and treatment. During twelve consecutive months we studied prospectively 99 patients with ARF diagnosed by conventional criteria, an incidence of 1,238 cases per million per year. ARF affected 1.78% of patients admitted to hospital. We analyzed age, sex, serum creatinine, diuresis, etiology, type of ARF, preexisting chronic diseases, treatment, complications and outcome. Preexisting chronic diseases were common, the most frequent being hypertension (54%) and diabetes (39%). Previous treatments for cardiovascular diseases were frequent (angiotensin-renin system blockade 35.4%, diuretics 50.5%). 79% of ARF arose in hospital, 21% outside hospital. ARF was pre-renal in 60%, renal in 31% and post-renal in 9%. 34.7% were caused by volume depletion, 23.4% by low cardiac output and 23.4% by infection. 44.4% of ARF patients had oliguria or anuria latrogenic factors contributed to the ethiology of ARF in 35.3% of patients. Hospital stay was doubled by ARF the presence of ARF and the mortality was 36.4%. The rate was higher in ARF arising in hospital than in ARF acquired before admission. Factors that had a significant influence on the mortality rate were comorbid conditions, oliguroanuria, ARF of renal origin and serum albumin. We conclude that ARF has a high incidence, morbidity and mortality in this elderly population. Volume depletion, associated cardiovascular pathology and pharmacological treatment are important etiological factors in those with ARF outside hospital. Adequate treatment of ARF and avoidance of nephrotoxic medications are necessary in hospital.

In spite of improvements in chemical structure, contrast media assisted X-ray examination is still the third leading cause of hospital-acquired acute renal failure. An increase >50% or >88 micro mol/L in S-creatinine is a clinically important acute renal failure. The peak in S-creatinine occurs within 2-5 days after exposure. The frequency of oliguria, transient or permanent haemodialysis is unknown. The cause is a hypoxic tubular injury due to vasoconstriction with release of free oxygen radicals. Major risk factors are prior renal insufficiency and diabetes mellitus. Minor risk factors are congestive heart disease, dehydration, hypotension, hypoxia, amount of contrast, ionic and high osmolar contrast, repeated examinations at short intervals, abdominal examination, and perhaps age, smoking, hypercholesterolaemia, and use of Non-Steroidal Anti inflammatory Drug. Prevention seems possible by omission or reduction of contrast, ameliorating predisposing factors, saline hydration 24h before and after exposure, and 600 mg acetylcysteine orally twice daily 24h before and after exposure. A three-day treatment with 20mg nitrendipine daily, starting 1 day before examination may also be preventive. The present research is unfortunately characterised by small numbers, lack of clinical important renal failure, and lack of long term results. The latter may be important after new data indicate that radiation may trigger a chronic oxidative process through a similar pathway.

Diabetic patients undergoing hemodialysis demonstrate much worse survival rates than do nondiabetic patients undergoing hemodialysis. To search for risk predictors, a prospective cohort study was performed with 245 hemodialysis patients, including 84 with diabetes mellitus, for 2 yr. C-reactive protein, troponin T (TnT), total, HDL, LDL, and lipoprotein(a) cholesterol, apoA2, apoB, triglyceride, fibrinogen, D-dimer, albumin, and creatinine levels and clinical characteristics at the time of entry were recorded. Survival rates were compared with Kaplan-Meier and Cox regression analyses. Forty-three diabetic patients and 30 nondiabetic patients died. Among diabetic patients, oliguria (<200 ml/d) (relative risk, 3.24; 95% confidence interval, 1.63 to 6.41; P = 0.001), elevated C-reactive protein levels (relative risk, 2.57; 95% confidence interval, 1.06 to 6.18; P = 0.035), and elevated D-dimer levels (relative risk, 2.36; 95% confidence interval, 1.11 to 5.01; P = 0.025) predicted all-cause mortality rates. Oliguria was by far the most important predictor, particularly for infectious disease-related death (relative risk, 23.35; 95% confidence interval, 2.60 to 209.97; P = 0.005). Among nondiabetic patients, elevated TnT levels (relative risk, 4.00; 95% confidence interval, 1.58 to 10.10; P = 0.003), elevated D-dimer levels (relative risk, 3.45; 95% confidence interval, 1.27 to 9.33; P = 0.015), and low cholesterol levels (relative risk, 3.61; 95% confidence interval, 1.34 to 9.71; P = 0.011) predicted all-cause mortality rates. Subdivision of the causes of death among nondiabetic patients revealed that TnT levels predicted cardiovascular mortality rates (relative risk, 5.38; 95% confidence interval, 1.11 to 26.10; P = 0.037) and infectious disease-related mortality rates (relative risk, 12.02; 95% confidence interval, 1.42 to 191.96; P = 0.023). In conclusion, mortality predictors among patients undergoing hemodialysis differed substantially between diabetic and nondiabetic patients. Strategies to reduce mortality rates should consider these differences.

A 64-year-old man was admitted to our hospital because of general fatigue and drowsiness. On admission, a physical examination disclosed dehydration and a laboratory investigation revealed the following values: plasma glucose, 1309 mg/dl; serum sodium, 160 mmol/l; potassium, 3.0 mmol/l; urea nitrogen, 65 mg/dl; creatinine, 2.73 mg/dl; and plasma osmolarity, 403 mOsm/kg. Urine ketone bodies were negative. A diagnosis of hyperosmolar non-ketotic diabetic syndrome was made, and hydration with an infusion of hypotonic saline (0.45%) and insulin therapy were immediately started. However, despite adequate rehydration and correction of blood glucose, his serum creatinine level increased to 3.1 mg/dl, while oliguria and myoglobinuria developed on the 4th hospital day, with serum creatine kinase increasing up to a maximum level of 16,749 IU/l, suggesting rhabdomyolysis. A final diagnosis of hyperosmolar non-ketotic diabetic syndrome associated with rhabdomyolysis and acute renal failure was made. His renal function gradually improved without hemodialysis, though acute renal failure due to rhabdomyolysis with hyperosmolar non-ketotic diabetic syndrome can sometimes be fatal. This rare case is presented along with a review of literature.

Intravenous immunoglobulins (i.v.IG) are increasingly used in various clinical situations for which they have been considered to be safe and effective. However, since 1987, some cases of renal toxicity have been reported. Forty-nine cases of acute renal failure have been notified to the French Regional Pharmacovigilance Centers between 1992 and mid 1998. In this series, marked serum creatinine increases (mean 387%+/-181%) appeared within 8 h to 8 days after initiation of i.v.IG therapy. Oliguria was observed in 80% of the cases. Haemodialysis was required for 34% of the patients. The renal failure persisted for a mean duration of 10 days after discontinuation of the i.v.IG treatment. Although risk factors have not been definitely established, preexisting renal impairment and old age seem to predispose to i.v.IG-associated acute renal failure as well as diabetes mellitus or the use of diuretics. The mechanism of renal injury remains speculative but a hyperoncotic overloading may be contributory. Finally, close monitoring of renal function is required in patients with preexisting renal failure, with older age and with diabetes mellitus.

The development of acute renal failure (ARF) in the ICU setting carries a high morbidity and mortality. To assess the outcomes and its predictive factors in our ICU, we analyzed the data of patients with ARF treated during 18 months. The 33 patients included 21 men and 12 women of mean age 51 +/- 21.7 years (13 to 87). Sepsis with multi-organ dysfunction (MOD) was the leading cause of ARF (58%). Comorbid conditions were malignancy in 30% of patients, diabetes mellitus in 24%, hypertension in 21%, ischemic heart disease in 21%, liver disease in 15%, and chronic renal failure in 15%. Predisposing factors were hypotension in 67% of cases, dehydration in 36%, drug related in 33%, congestive heart failure in 24%, and liver cirrhosis in 6%. Twenty-five (76%) patients needed mechanical ventilation, 22 (67%) were anuric, 18 (55%) had MODS, and 15 (45%) needed inotropic support. Length of stay in hospital was 27.2 +/- 28.0 days (2 to 94). Nineteen patients (58%) were managed conservatively and 14 (42%) by renal replacement therapy. Patient mortality was 67% and renal mortality 52%. The impact of the following factor: was assessed on patient and renal outcome was assessed ventilation support, presence of oliguria, need for inotropes, and presence of MOD. Patient mortality was significantly influenced by an elevated odds ratios (OR) (95% CI): mechanical ventilation [OR = 34 (95% CI 1.95 to 538)], and presence of MODS [OR = 12.3 (95% CI 2 to 75)]. Renal mortality was influenced by mechanical ventilation [OR = 12.3 (95% CI 1.6 to 119)], oliguria [OR = 12 (95% CI 2 to 72)], inotrope support [OR = 10 (95% CI 2 to 52), and MOD [OR = 35 (95% CI 3.5 to 35.0)]. This study confirms the high patient and renal mortality of ARF among patients to ICU. The four parameters were excellent predictors of renal outcome, while only the need for mechanical ventilation and the presence of MOD were predictors for patient survival.

Acute renal failure (ARF) occurs in wide range of conditions, making the evaluation of its prognosis a difficult task. Data regarding prognostic factors in ARF in a general population in developing countries are scarce. The objective of the study was to describe predictors of mortality in ARF that are relevant in the developing world. This prospective study was carried out over a one-year period; all hospitalized adults with ARF were included in the study. Predictors of mortality studied included causes of ARF, pre-existing diseases, and severity as well as complications of ARF. Of 33,301 patients admitted during the study period, 294 (0.88%) were either admitted with or developed ARF after hospitalization. Mean age was 43.9 +/- 16.9 (18-86 yrs). Sepsis was the most common cause (63.26%). Pre-existing diseases like cardiovascular disease (CVSD), respiratory system disease (RSD), central nervous system disease (CNSD), hypertension, diabetes mellitus (DM), and malignancy were significantly higher in elderly as compared to younger patients. On univariate analysis sepsis, hypoperfusion as a cause of ARF and hospital-acquired ARF were associated with higher mortality. Pre-existing diseases viz. RSD, CVSD, CNSD, and DM had higher mortality. Among the severity and complications of ARF, oliguria, bleeding and infection during the course of ARF and critical illness were predictors of poor outcome. Age > 60 yrs was associated with significantly higher mortality. However, on multivariate analysis, only critical illness (odds ratio 37.3), age > 60 years (odds ratio of 5.6), and sepsis as cause of ARF (odds ratio of 2.6) were found to be independent predictors of mortality.

A 52-year-old Indian woman with underlying diabetes mellitus and hyperlipidemia, presented with generalized musculoskeletal pain and oliguria for three days. The patient was taking 80 mg of simvastatin initiated 20 days earlier after cardiac catheterization for an inferior myocardial infarction. Laboratory investigations revealed the following serum levels: creatine kinase 81,620 U/L, aspartate aminotransferase 2497 U/L, alanine aminotransferase 1304 U/L, blood urea nitrogen 21.7 mmol/L, creatinine 447 micromol/L, Free T4 12.6 pmol/L, and thyroid stimulating hormone (TSH) 22.7 microIU/L. Simvastatin was discontinued and the patient received forced alkaline diuresis. Her hypothyroidism was treated with thyroxin, which was continued upon discharge, and her renal function recovered within two months. This case report discusses the incidence of rhabdomyolysis in a patient with primary hypothyroidism receiving large doses of simvastatin.
