An analysis of 4 cases of the thrombotic thrombocytopenia in children of 4 to 10 years of age is performed. The disease was characterized by fever, purpura, headache and abdominal pains, arterial hypertension, microangiopathic haemolytic anemia, thrombocytopenia, increase of blood urea and serum creatinine, micro-haematuria and proteinuria. The duration of the disease was from 4 days to 7 months. Anuria, gangrene of the ears, scrotum, penis and soft tissues of legs and feet were registered in a 5-year-old patient with a fulminant disease. The cause of death of other patients was heart failure with acute lung oedema, brain haemorrhages and haemorrhagic pancreonecrosis. The diagnosis of the thrombotic thrombocytopenia was confirmed by the finding in the autopsy material of thrombotic microangiopathy of small arteries, veins, arterioles, venules and capillaries in kidneys and other organs and tissues. Kidney damage in fulminant disease is complicated by segmentary cortical necrosis, in a more prolonged disease--by glomerulosclerosis or mesangio-capillary glomerulonephritis.

Since the installation of an extracorporeal shock wave lithotriptor (ESWL) unit 12 months ago, 2000 lithotripsy procedures have been performed. Overall, 68.4% of patients were stone-free by the end of the first month. Residual lithiasis (fragments less than 0.5 cm) was seen in 19.7% of patients and significant lithiasis (fragments greater than 0.5 cm) was observed in 10.1%. Complications were obstruction, infection, headache due to the epidural anaesthesia, anuria, renal failure, perirenal haematoma and cardiac arrest. A number of patients required additional operative treatment; this was always endoscopic and no open procedures were performed. Hospitalisation averaged 1 day.

The Orellanus syndrome is a rare nephrotoxic disease caused by several fungi of the genus Cortinarius. For a long time the sole report of this syndrome was a mass intoxication in Poland. About 32 cases of Orellanus syndrome caused by Cortinarius orellanus, speciocissimus and splendens have been described in recent years. A few other species are also suspected of being nephrotoxic. The syndrome is characterized by a delayed latency period of 2 days to 3 weeks, and a chronic evolution involving fatigue, anorexia, headache, thirst, pains in the lumbar region and renal insufficiency with oliguria and anuria, and the clinical picture by reversible or irreversible interstitial nephritis. In this report the clinical and mycological features are summarized.

In the last ten years ivermectin appeared an efficient and safe alternative to diethylcarbamazine which is known to induce severe adverse reactions in loiasis, including encephalitis. After these results, large scale ivermectin treatments against onchocerciasis were carried out in Central Africa where loiasis is also endemic; and seven cases of severe reaction were reported in Cameroon since 1991, during these mass ivermectin treatments. In order to study adverse reactions in patients harbouring high load of Loa loa microfilariae (mf), we realized careful hospital based treatment in 112 patients with more than 3,000 mf/ml (ml) blood. Patients received once 200 micrograms ivermectin per kilogram at day 0 (D0). Clinical examination was made daily during the four following days (D1 to D4). Blood and urine samples were analysed before treatment and at D1 and D3. Lumbar puncture was made at D1 for 39 patients with more than 10,000 mf/ml; at D3 for the 49 following patients without consideration for the level of parasitaemia, and at D0 and D3 for ten voluntary patients. For analysis the patients were distributed in 3 groups according to initial parasitaemia: the first group included 50% out of the patients, those whose parasitaemia was fewer than 15,000 mf/ml blood; the second group included 25% patients whose parasitaemia was between 15,000 and 30,000 mf/ml; the third group included the last 25% patients whose parasitaemia was higher than 30,000 mf per ml blood. Adverse reactions were observed in 71% out of the patients. Symptoms described were fever, pruritus, headache, arthralgia. Most symptoms appeared 24 to 36 hours after treatment. Temperature increased significantly in group 3. Microfilaraemia decreased by 85% in the 3 groups during the 4 days following treatment. C-reactive-protein increased dramatically after treatment in all patients (p < 10(-4)). Some patients presented blood in urine in three groups but haematuria reached 35% of patients in group 3. Proteinuria is noted among 33% of all patients but 20% in group 1 and 2 versus 70% in group 3. Loa loa mf were observed in urine of half the patients, but in low amounts (< 10 mf per 50 ml urine). In cerebro-spinal fluid (CSF), some mf appeared at D1 or D3 in people heavily infected with Loa loa, reaching 80% of the patients of group 3. LP made at D0 in ten patients with parasitaemia higher than 30,000 mf/ml blood confirmed that CSF was naturally microfilaria free before treatment. One patient presented severe troubles with fever, asthenia and conscience troubles beginning at D3, reactive coma at D4, renal impairment with transitory anuria; progressive improvement in 2 weeks and complete recovery at D22; he presented 102 mf/ml CSF at D6. The study confirmed that ivermectin treatment is generally well tolerated. Among people with high Loa loa parasitaemia the symptoms after treatment are frequent but mild. However severe cases with conscience troubles are possible, and may occur in about 1% of subjects with more than 3,000 mf/ml blood. Severity of adverse reactions was linked to level of parasitaemia before treatment. The critical parasitaemia level which could lead to expect serious adverse effects seems to be 30,000 ml/ml blood. These informations should induce carefulness to carry out large scale treatments against filariosis in endemic areas of Loa loa.

We report on 10 patients with acute renal involvement in Hantaan virus infection observed at the Department of Nephrology, Faculty of Medicine, Skopje, Republic of Macedonia, during a period of 3 years (October 1987-July 1990). Eight patients were male and 2 were female, aged 37.5 +/- 4.8 years. The diagnosis of Hantaan virus infection was proven by an indirect immunofluorescent and ELISA test with a significant increase of the titer after a week to ranges from 1:512 to 1:2,048. Percutaneous renal biopsy was performed in 3 cases using standard procedures for optical and immunofluorescent microscopy. Fever, weakness, headache, conjunctival injection, hematuria, and lumbar pain were clinical features all patients had in common. Complete anuria was noted in 7 out of 10 and oliguria in the other 3 of the 10 cases with serum levels of creatinine 967 +/- 152.6 mumol/L. Other following laboratory findings were leukocytosis in 10 out of 10 patients, with neutrophylia, and reduction of serum sodium and potassium in 8 out of 10, and a decrease in serum complement C3 in 3 out of 10 patients. Percutaneous renal biopsy confirmed interstitionephritis in 2 out of 3 biopsied patients and acute diffuse proliferative glomerulonephritis in the third. Interstitial mononuclear infiltration with dominant T cells proven with monoclonal antisera (direct immunoperoxidase method) was present in all 3 cases. The outcome of the disease was good in 8 of the 10 patients with a development of polyuric phase and complete recovery of renal function later. One patient with interstitial lesions on biopsy developed chronic renal failure, and the other with a concomitant brucellosis died during the polyuric phase of the disease.

Six patients with severe and complicated falciparum malaria (6.7 +/- 2.7 WHO criteria) were admitted to our Intensive Care Unit. All patients acquired the disease while travelling in tropical Africa without appropriate chemoprophylaxis. The clinical manifestations included hyperpyrexia (all patients), chills (4), sweating (2), asthenia (3), anorexia (2), headache (1), arthralgias (1), vomiting (4), diarrhoea or abdominal discomfort (3), jaundice (2) and disturbances of consciousness (4). All patients had anemia, thrombocytopenia, hyponatremia, hypoproteinemia, hypoalbuminemia, hypocalcemia and acute renal failure, in one case associated with anuria. A low grade parasitemia was observed in two patients and a high grade parasitemia (20%-58% of erythrocytes) in four. Exchange transfusion was performed only in high parasitemic patients and all of them survived. All patients were treated with quinine, a sulfonamide and pyrimethamine. Additionally, five patients received oxytetracycline, doxycycline or clindamycin. Three patients required hemodyalisis. Five patients had delirium, coma or seizures. All patients had at least one sign of hepatic impairment: liver enlargement, jaundice or increased bilirubin or aminotransferase levels. Two patients had spleen enlargement. Laboratory findings suggested disseminated intravascular coagulation in four patients. Four patients developed pulmonary changes and three of them required mechanical ventilation. A Swan-Ganz catheter was placed in four patients. In three of them (two with pulmonary edema) the pulmonary capillary wedge pressure was initially increased, which suggested a cardiogenic or hypervolemia mechanism, but soon returned to normal level. One patient with low grade parasitemia died because of adult respiratory distress syndrome after 18 days. In our series, the degree of parasitemia was not related to the severity of the disease.

During the 1995 outbreak of Ebola hemorrhagic fever in the Democratic Republic of the Congo, a series of 103 cases (one-third of the total number of cases) had clinical symptoms and signs accurately recorded by medical workers, mainly in the setting of the urban hospital in Kikwit. Clinical diagnosis was confirmed retrospectively in cases for which serum samples were available (n = 63, 61% of the cases). The disease began unspecifically with fever, asthenia, diarrhea, headaches, myalgia, arthralgia, vomiting, and abdominal pain. Early inconsistent signs and symptoms included conjunctival injection, sore throat, and rash. Overall, bleeding signs were observed in <45% of the cases. Typically, terminally ill patients presented with obtundation, anuria, shock, tachypnea, and normothermia. Late manifestations, most frequently arthralgia and ocular diseases, occurred in convalescent patients. This series is the most extensive number of cases of Ebola hemorrhagic fever observed during an outbreak.

This paper describes the clinical findings in 206 patients with dengue fever (DF) or with dengue hemorrhagic fever (DHF) during the epidemic of 1996 at Lucknow. The age group affected most was 11 to 30 years and 21% of the patients were less than 10 years old. The male:female ratio was 1.9:1. The onset was abrupt in all the patients, severe frontal headache was observed in 97%, myalgia in 90%, skin rash in 40%, vomiting in 29% and arthralgia in knee and hip joints in 9%. Anuria was seen in two patients. Lymphadenopathy was noted in 14%, hepatomegaly in 4%, being associated with mild jaundice in one patient, and splenomegaly in 2% of the patients. Involvement of the heart and lungs was seen in one patient each and no case with encephalitis was recorded. Hemorrhages from various sites were observed in 54% patients and 17 patients had profound shock. The commonest bleeding site was gums. Profound shock was preceded by various warning signs, the commonest being sudden hypotension. Among the patients with profound shock the mortality was 47% while the overall fatality rate was 3.8%. A number of the risk factors existed for a long time in this part of the world, but what precipitated the present epidemic at this time, is not known.

A formerly healthy 32-year-old woman was hospitalized for a closer examination of undiagnosed fever with mild headache. Despite lack of distinct findings on physical and laboratory examinations at admission, she suddenly developed anuresis due to acontractile neurogenic bladder. On the basis of her symptoms and the faint nuchal rigidity revealed later, as well as the results of cerebrospinal fluid analyses, a diagnosis of aseptic meningitis was eventually reached. While aseptic meningitis subsided within 3 weeks, about 10 weeks, including a 26-day period of anuria, was necessary for complete restoration of normal voiding function, necessitating intermittent self-catheterization. Acute urinary retention should be considered an uncommon but critical manifestation of aseptic meningitis.

Only scarce data are available on chronic copper poisoning in general toxicology literature. This paper reports four patients with chronic copper poisoning and one patient with acute poisoning. The cases with chronic poisoning in our study consisted of four members of a farmer family presenting to the emergency department (ED) with malaise, weakness, abdominal pain, headache, dizziness, tightness in the chest, leg and back pain, accompanied by significant anemia (hemoglobin [Hb]: 8.7 - 9.5 g/dl). They were hospitalized and investigated thoroughly, although there were no other findings or clues enlightening the etiology of anemia. The anemia was attributed to chronic copper exposure acquired from vegetables containing copper. The diagnosis was established by ruling out other possible etiologies and history coupled with laboratory findings. The patients were discharged with the recommendation on diet to avoid consumption of pesticide-treated vegetables. Their Hb values were between 10 and 11.4 g/dl on the 15th day, and between 12 and 14 g/dl after two months. Their symptoms had also resolved completely in two months. The patient with acute intoxication (5th case) had ingested copper oxychloride with suicidal intent. He was admitted with anuria and hemolytic anemia. After being hospitalized for fifteen days, he was diagnosed with chronic renal failure and was scheduled for a dialysis program. Acute poisoning is more deliberate, while chronic exposure may result in atypical findings. In conclusion, physicians working in primary care and EDs should consider copper poisoning in patients presenting with anemia, abdominal pain, headache, tightness in the chest, and leg and back pain.
