A 45-year-old man presented with severe hypertension, headache, cortical blindness, and a depressed level of consciousness. A second patient, a 33-year-old woman, was admitted with pre-eclampsia. She developed lethargy, headache, bilateral extensor plantar responses, and seizures. The third patient, a 62-year-old man, presented with acute renal failure due to necrotising vasculitis and glomerulonephritis. Five days after treatment with immunosuppressive drugs had been initiated, he developed headache, confusion, seizures, and cortical blindness. Hypertensive encephalopathy is characterised by headache, vomiting, disturbances in cognition and level of consciousness, visual abnormalities, and seizures. Imaging studies often demonstrate oedema of the white matter in the posterior parietal and occipital areas of the brain. This so-called reversible posterior leucoencephalopathy syndrome is well known in patients with severe hypertension, but it is also associated with immunosuppressive drug use and renal failure. It can be recognised by its fairly characteristic clinical features (different combinations of headache, vomiting, changes in cognition and level of consciousness, seizures, muscle weakness, and visual symptoms) and by its specific imaging findings. Treatment consists of reducing the blood pressure and reducing or discontinuing the use of immunosuppressive drugs. If the treatment is started promptly, symptoms and imaging abnormalities are usually reversible.

Cocaine use has increased considerably during the last twenty years and several related complications can be identified. Clinical features of cocaine intoxication are variable, but predominantly involve cardiovascular events. Chest pain is the most main complaint; myocardial ischemia must be ruled out. Other cardiovascular manifestations are left ventricular dysfunction, arrhythmia, endocarditis and aortic dissection. Non-cardiac complications include neurological (seizures, stroke, cerebral hemorrhage), respiratory (asthma, interstitial pneumonitis, pulmonary edema), renal (acute renal failure, rhabdomyolysis) and obstetrical disorders. Detection of cocaine in the urine provides the diagnosis. Symptomatic treatment is generally given, combining conventional treatment of the complication and broad use of benzodiazepines.

We report the morbidity and mortality in extremely low birth weight neonates (ELBW) from a tertiary care hospital over seven years (1994-2000). Data regarding maternal and neonatal details was obtained from old records, computer database and medical files. Of the 12,807 live births during this period, 137 (1.07%) were ELBW infants. All of them were managed without surfactant. Overall, 67 infants (48.7%) survived to discharge. The most commonly encountered morbidities were hyperbilirubinemia(65%), respiratory distress(65%), sepsis(52%), intraventricular hemorrhage(29%), pneumonia (25%) and retinopathy of prematurity(24%). Need for resuscitation, pulmonary hemorrhage, seizures, acute renal failure, sclerema and air leak syndromes were significantly associated with mortality. Sepsis accounted for 41% of all deaths while immaturity was the second most important cause, accounting for 24% deaths. The average length of stay for survivors was 49 days (SD +/- 15.9 days)

Multiple renal adverse effects have been anecdotally reported with the ingestion of 3,4-methylenedioxymethamphetamine (Ecstasy), a widely used recreational drug. These side effects include acute renal failure, necrotizing vasculitis, and hyponatremia, the mechanisms for which are unknown. We report a case of transient acute proximal tubular injury and hyponatremia associated with Ecstasy use. An 18-year-old woman presented with new onset seizures and polydipsia. Her initial laboratory evaluation revealed hyponatremia (Na 117 mEq/L), polyuria (urine output >400 mL/h for several hours), renal glycosuria (blood glucose 120 mg/dL, urine glucose >1,000 mg/dL), and solute diuresis (urine osmolality 552 mOsm/kg H2O). Urine electrolyte values reflected a low tubular reabsorption of phosphorus (TRP) of 68.1% (expected TRP >85% at serum P 2.3 mg/dL) with an appropriate transtubular potassium gradient of 3.0 (serum K 3.7 mEq/L). Her hyponatremia was slowly corrected. A repeat TRP after 48 h had normalized to 86.5%, and her glycosuria resolved. An extensive toxin screen was later reported positive for Ecstasy. To our knowledge, this is the first example of an acute and transient proximal tubular injury with Ecstasy ingestion. This complication may become more apparent with increasing use of this drug.

Acute renal failure is a common occurrence in sepsis, but is rarely reported in meningococcemia. We present a young child diagnosed with fulminant meningococcemia who had several poor prognostic factors, including hypotension, thrombocytopenia, purpura fulminans, seizures, the absence of meningitis with meningococcemia, and acute renal failure, which was successfully treated with peritoneal dialysis. Peritoneal dialysis was started on the 5th day because the patient had been anuric for 48 h. At that time, analysis showed that the child was both hypokalemic and hypophosphatemic. His serum blood urea nitrogen was 61 mg/dl, creatinine 2.75 mg/dl, potassium 2.8 mEq/l, and phosphorus 0.7 mg/dl. Urine output began on the 12th day post admission and normalization of serum creatinine was achieved on the 26th day. In conclusion, renal failure is an important complication of meningococcemia and, to be effective, sometimes long-term peritoneal dialysis is required. Profound metabolic abnormalities, such as hypokalemia and hypophosphatemia, may occur paradoxically in the presence of oliguria.

A 14-year-old girl with rapidly progressive glomerulonephritis was transferred to our hospital because of acute renal failure. A diagnosis of Wegener granulomatosis was made according to the symptom triad of a renal biopsy demonstrating crescentic glomerulonephritis, severe sinusitis, and serological findings of raised proteinase 3 anti-neutrophil cytoplasmic antibody level. In spite of combination therapy with methylprednisolone, cyclophosphamide, and plasma exchange, her renal function gradually deteriorated. Thereafter, she suffered a severe headache and generalized seizures. Brain computed tomography (CT) scan revealed bilateral low-density areas in the parieto-occipital lobes. Magnetic resonance imaging (MRI) disclosed a high-intensity area on T2-weighted images and a low-signal intensity area on T1-weighted images in the same lesion. Follow-up brain CT scan 3 weeks and MRI 2 months after the first studies showed complete resolution of the abnormal lesions, which indicated reversible posterior leukoencephalopathy syndrome. In addition to renal failure, hypertension, and cyclophoshamide, the primary disease may have played a role in the development of this uncommon syndrome in our patient.

Falciparum malaria affect all ages with multiple-systemic complications which varies in different age group. We studied 242 children with complicated Falciparum malaria with a median age of 6.5 years to look for occurrence of different complications in younger and older age groups and overall mortality picture. Unarousable coma (40.5%), severe anemia (26.03%), repeated seizures (46.2%) and hepatopathy (32.2%) were commonest complications. Under five children had higher risk of development of cerebral malaria (P<0.01), severe anemia (P<0.05) and seizures (P<0.001); whereas above five children had higher risk of acute renal failure (P<0.05) and malarial hepatopathy (P<0.02). Over all mortality was 9.9%, cerebral malaria being the commonest cause (6.6%). Multi-system involvement was seen in 58.4% cases of death. Children having pulmonary edema, shock and cerebral malaria had high case fatality rate.

Recently observations of rhabdomyolysis in patients treated with tacrolimus have been reported. The authors present a kidney transplant patient who had an epileptic seizures, severe rhabdomyolysis, and acute renal failure. The patient was initially immunosuppressed with tacrolimus and chimeric CD25 monoclonal antibody. After intensive therapy with plasmapheresis, CVVH, and dialysis, the patient completely recovered at 11/2 year his serum creatinine is 1.2 mg/dL.

An 18-year-old woman diagnosed with piridoxine-resistent primary hyperoxaluria type 1 (PH-1) and progressive renal insufficiency complicated with acute renal failure of obstructive origin who developed systemic oxalosis affecting the heart (cardiomyopathy), the skin (cutaneous ulcers) and vascular system (lower limb ischemia, as well as pulmonary and cerebral microcirculatory blockage resulting in pulmonary hemorrhage and tonic-clonic general seizures. As conventional hemodialysis (HD) or peritoneal dialysis (PD) are unable to eliminate enough oxalate to avoid a continuous positive balance, long daily sessions (6-7 h) of high-flux hemodialysis (highly permeable polyamide membrane of 2.1 m2) for 67 consecutive days normalized blood oxalate levels and reversed the systemic complications secondary to the calcium oxalate crystals deposit. The patient underwent a combined liver-kidney transplantation and has progressed well to the present time. The most important factors in PH-1 treatment are analyzed. Even though combined liver-kidney transplantation is the treatment of choice and should be performed before the glomerular filtrate rate (GFR) falls below 25 mL/min/1.73 m2, intensive HD becomes necessary to prevent oxalosis in the face of acute renal failure. Also, as our case shows, intensive HD can achieve a negative oxalate balance and reverse both the systemic lesions and the oxalate deposits.

Sixteen fatal dog envenomations by the snake Vipera palaestinae over a 14-y period are described. Most envenomations occurred during the late night hours in the warm months, and 8/16 dogs were bitten on the limbs. The most frequent clinical signs upon admission were soft tissue swelling and edema, local pain, depression, bleeding, lameness, dyspnea, and 6 dogs were in shock. Thrombocytopenia was present in 14/16 cases and increased hematocrit (13/16) and hemoglobin (9/16) concentration were the most common hematological abnormalities upon admission. Biochemical abnormalities included increased activities of muscle enzymes and alkaline phosphatase, hypocalcemia, and hypocholesterolemia. Creatine kinase activity was markedly increased in 2 dogs. During hospitalization serious complications in many dogs were disseminated intravascular coagulation, acute renal failure, seizures, cardiac arrhythmias, acute necrotizing pancreatitis and severe laryngeal edema; these required intensive and expensive therapies. Specific antivenin (10 ml) administered to 8/16 dogs did not prevent death. Glucocorticosteroids were given in 8 cases; however, their use was associated with complications. Four dogs suffered sudden death, 2 of which died 1-2 d after discharge. Necropsy performed on 3/16 dogs found soft tissue swelling and local bleeding at the envenomation sites as well as bleeding in several distal body organs and tissues.
