Fever of unknown origin: a report of 57 cases.
Fever of unknown origin (FUO) is defined as the body temperature higher than 38.3 degrees C on several occasions and lasting longer than 3 weeks, with the aetiology remaining uncertain after 1 week of investigation. In this study, we reviewed 57 patients with FUO hospitalised in our inpatient department between 1998 and 2003. The median age of the patients was 44 years (17-84), and 26 were males (46%), while 31 were females (54%). In 24 patients (42%), infectious diseases such as tuberculosis (12 patients) and brucellosis (5 patients) were found under the aetiology of FUO. Inflammatory rheumatic diseases were the second most common cause of FUO (17 patients, 30%), while malignancies were found in 10 patients (18%). In six patients (10%), aetiology could not be identified. In conclusion, infectious diseases especially tuberculosis and brucellosis are the leading causes of FUO in our country.

Acute renal failure due to leukaemic infiltration in chronic lymphocytic leukaemia: case report.
A 73-year-old woman was presented with altered mental status and disorientation. She was diabetic and hypertensive, and she had experienced an ischemic cerebrovascular accident 3 years ago. Physical examination revealed the findings of chronic obstructive pulmonary disease, cor pulmonale and congestive heart failure. Hepatomegaly, splenomegaly and ascites were found and might be associated with postsinusoidal portal hypertension secondary to congestive heart failure. Laboratory tests showed uremia, lymphocytosis and thrombocytopenia. Neurologic findings were related with uremia and hypoxia. Multiple pathologic lymphadenopathies were seen in abdominal ultrasonography and thoracic computed tomography. Bone marrow histology indicated chronic lymphocytic leukaemia (CLL). The reason for acute renal failure was leukaemic infiltration of the kidneys due to CLL that was shown with renal biopsy. Blood urea nitrogen (BUN) and serum creatinine responded well to cyclophosphamide and methyl prednisolone treatment. In CLL, direct renal involvement is frequently seen in autopsy studies especially in advanced disease, however, renal failure due to leukaemic infiltration is extremely rare.

Bilateral renal artery stenosis after abdominal radiotherapy for Hodgkin's disease.
A 49-year-old woman was admitted with fatigue, dyspnoea, pretibial oedema and decreased daily urination. Seven years ago she was treated with doxorubicin, bleomycin, vinblastine and dacarbazine, alternating with mechlorethamine, vincristine, procarbazine and prednisone and 80 Gy abdominal radiotherapy for Hodgkin's disease. Two years later, malignant hypertension was diagnosed. Angiotensin-2 antagonist and beta-blocker treatment was given. After increased serum creatinine levels were determined, renal angiography was performed and total obstruction in the left renal artery and near total obstruction in the right side was observed. She was admitted to our clinic with oliguria, and acute renal failure was diagnosed. Balloon angioplasty and stent implantation was performed to the right renal artery. After a polyuric period, serum creatinine reduced to near normal levels. Angiotensin-2 antagonist treatment worsened the course in this patient. Patients with resistant hypertension occurring years after abdominal radiotherapy should be evaluated for renal artery stenosis.

Osteodystrophy in posthepatitic cirrhosis.
This study investigated the incidence and severity of hepatic osteodystrophy in patients with posthepatitic liver cirrhosis, and the role of hepatocellular injury in bone loss. Twenty-four patients (15 females and 9 males, mean age 49 +/- 13 years) with posthepatitic cirrhosis were enrolled in this study. The control group consisted of 22 healthy age and sex matched adults. The bone mineral density (BMD) was evaluated by dual energy x-ray absorptiometry of the L1-L4 vertebral bodies. A detailed questionnaire was used to assess the epidemiological findings. A statistically significant decrease in BMD of the patients was observed. There were no significant differences in the alkaline phosphatase, parathyroid hormone, calcitonin, 25-hydroxyvitamin D, osteocalcin, free testosterone, luteinizing hormone, follicle stimulating hormone, and estradiol levels, oral calcium intake, urinary calcium, phosphorus and hydroxypyroline excretion between patients and controls. The control group smoked more cigarettes, consumed more coffee and meat, and were exposed the sun light for a longer period than the study group. Multiple regression analysis showed that osteopenia depends significantly on the extent of liver disease. The data shows that the patients with posthepatitic cirrhosis had osteopenia, and that cirrhosis was a direct and independent risk factor.
