Five cases of airport malaria were observed in Geneva in the summer of 1989. All the patients lived within 2 km of Geneva-Cointrin International Airport. They were hospitalized between July 14 and August 2 for high fever. None had received a recent blood transfusion, an i.v. injection or traveled to a tropical country, except for one, a former pilot, whose last brief visit had been a year earlier. High minimum temperatures between July 6 and 10 in all likelihood allowed the survival of infected anopheles introduced by an aircraft. P. falciparum was identified in the blood smears of all the patients. Four had one or more symptoms of serious malaria and received intravenous treatment. In the fifth patient, treatment with cotrimoxazole for suspected acute pyelonephritis made diagnosis particularly difficult because the malaria infection was partially controlled by the antibiotic therapy. The time necessary for diagnosis of malaria varied from 5 to 31 days in the 5 cases. Airport malaria has been observed over the past twenty years in Europe, particularly in the summer, and is often serious because of late diagnosis and the type of plasmodium most frequently involved, P. falciparum. This diagnosis should be considered in patients with high fever of unknown origin, even when they have not travelled to an endemic zone.

Diabetes mellitus is a common multisystemic disease with serious effects on the genitourinary system. In the radiology literature, little attention has been paid to developing an integral approach to imaging of the genitourinary tract in diabetes. The long-term effects of diabetes on the genitourinary system include diabetic nephropathy, papillary necrosis, renal artery stenosis, diabetic cystopathy, and vas deferens calcification. Diabetes-associated urinary tract infections include renal and perirenal abscesses, gas-forming infections such as emphysematous pyelonephritis and emphysematous cystitis, fungal infections, and xanthogranulomatous pyelonephritis. Diabetes-associated genital infections include Fournier gangrene and postmenopausal tubo-ovarian abscess. In a diabetic with fever of unknown origin or in the event of a persistent infection in a diabetic with clinical deterioration despite use of antibiotics, radiologic studies can demonstrate the presence of genitourinary complications. Finally, radiologists should be aware of the risk of contrast material-induced nephropathy in diabetics.

In immunocompromised subjects pyelonephritis is not more frequent than in healthy subjects and has the same clinical presentation. This is not true for kidney transplant recipients, in whom the physician is faced with fever of unknown origin. However, diagnosis of urinary tract infection is soon made by dipstick and confirmed by the laboratory finding of leucocyturia and bacteriuria. Degradation of renal function indicates that the renal tissue is infected. Treatment must be immediate and prolonged during four weeks. Return to normal renal function is then the rule.

Renal subcapsular abscess is a very rare disease that is defined by a suppurative process localized to a space between the renal capsule and the renal parenchyma. The course and management of subcapsular abscesses have received less attention than those of renal and perirenal abscesses. We describe a 63-year-old diabetic woman who presented with intermittent fever of 1 month's duration. She was initially treated for suspected acute pyelonephritis then referred to our hospital because of poor clinical response to cefazolin plus gentamicin. Computed tomography of the abdomen revealed a huge subcapsular abscess with displacement and compression of the left renal parenchyma. A percutaneous catheter was inserted and left in place for 8 days; a total of approximately 850 mL of pus was drained. Culture of the pus yielded Klebsiella pneumoniae and Enterobacter cloacae. A 2-week course of moxalactam was administered on the basis of the results of in vitro antibiotic susceptibility testing. The distorted renal parenchyma appeared normal at sonographic follow-up examination 3 weeks after hospitalization. The course and management of this rare entity are presented as a reminder to physicians that renal subcapsular abscess could manifest as fever of unknown origin in a diabetic patient. A high degree of clinical suspicion is required for early diagnosis and treatment in order to achieve a satisfactory outcome.

We report an 8-year-old boy with acute focal bacterial nephritis (AFBN). At the age of 3 months, he had a history of urinary tract infection and vesicoureteral reflux. He was admitted to our hospital because of high fever and costovertebral angle pain. Although acute pyelonephritis was suspected, neither pyuria nor cultures of blood and urine were positive. An initial ultrasonogram (US) of his kidneys was normal except for bilateral hydronephrosis. Two days later, however, a computed tomography (CT) revealed a poorly enhanced mass in the upper pole of the right kidney. Similar findings were also observed by US. Under the diagnosis of AFBN, he received antibiotics for 3 weeks. Voiding cystourethrogram showed both-sided vesicoureteral reflux and he underwent an operation. At present the mass of the kidney still remains, albeit its size tends to decrease. We suggest that an early examination of US or enhanced CT is necessary in cases with fever of unknown origin, considering the possibility of AFBN even if neither pyuria nor cultures of urine are positive.

This prospective study was done to assess the frequency of acute pyelonephritis (APN) in febrile children with positive urine culture as documented by Tc99m DMSA scintigraphy (DMSA) and the frequency of vesicoureteric reflux (VUR) in these children. Secondly, to determine the frequency of APN, in febrile children with supportive evidence for UTI but with negative urine culture, as documented by DMSA and frequency of VUR in them. Thirdly to stress the utility of DMSA to diagnose APN in urine culture negative febrile children and to suggest DMSA as a clinical tool in evaluation of fever of unknown origin (FUO). This study included 42 children with positive urine culture and 26 children with negative urine culture who had supportive evidence of UTI as determined by the predetermined criteria and diagnosed to have APN by DMSA. All of them had ultrasonogram (USG), DMSA and voiding cystourethrogram (VCU). They were followed up for a minimum period of 6 months. Out of the 42 children with positive urine culture 92.9% had features of APN in the DMSA of whom 82.1% had vesicoureteric relux (VUR). The DMSA was abnormal in 26 children with negative urine culture, of whom 65.4% had VUR. Ultrasound suggestive of parenchymal change was observed in 47.6% in the culture positive group and 65.4% in the culture negative group. In conclusion, it is suggested, that DMSA is a useful investigation for the diagnosis of APN in febrile UTI. DMSA is indicated in febrile children with negative urine culture but with supportive evidence of UTI and in FUO. An abnormal DMSA is a strong indication for work up for VUR.

The distribution of the disorders causing Fever of Unknown Origin (FUO) may differ according to the geographic area and the socioeconomic status of the country. FUO has not been appropriately investigated in children and adolescents in Georgia and therefore a study was undertaken to determine its causes and clinical characteristics. A total of 52 children fitting the classical FUO criteria seen in our clinic between 2003 and 2005 were investigated retrospectively. 27 (51,9 %) were boys and 25 (48,0%) were girls. 3 children (5,7 %) were less than 3 years old, 4 (7,6%) were 3-9 years old, 14 (26,9 %) were 10-14 years old and 32 (61,5%) were 15-18 years old. The mean age was 15,9 +/-4,8 years (range 1 year-18 years). 25 children (48,0 %) had a prolonged fever that had lasted for 15-30 days, 15 (28.8 %) for 31-60 days, and 12 (23.0 %) had fever lasting for more than 60 days. The most common causes of FUO were sepsis (10/52), tuberculosis (9/52), pneumonia (8/52), pyelonephritis (5/52), collagen tissue disorder (2/52), neoplasm (2/52), and miscellaneous (9/52). In 7 (13,4 %) of the cases the etiology could not be found. Some derivative hematological parameters--leukocytic index of intoxication, organism's allergisation index, ratios lymphocytes/neutrophils and eosinophils/lymphocytes and adaptation reactions can be helpful to distinguish severe infections. Precise evaluation of hematological changes can be useful for differential diagnosis of FUO. The most common cause of FUO in children and adolescents in Georgia remains infection.

The aim of this study is to report the extrarenal computerized tomography (CT) findings in patients with acute pyelonephritis (APN). Twenty-one CT examinations of 20 patients [19 women and one man, with ages ranging from 18 to 57 years (mean -35.2 years)], presenting either with a clinical diagnosis of APN (n=17) or with a suspected acute appendicitis, fever of unknown origin, and adult respiratory distress syndrome, one in each, were retrospectively reviewed. None had a known preexisting systemic disease. Results showed that renal abnormalities were seen on CT in all patients. In addition, ascites was detected in all women patients associated with subcutaneous edema in five of them. A thickened gallbladder wall was found in 19 cases, all were women, and periportal tracking and a dilated inferior vena cava in 17 CTs. Pleural effusion and thickened interlobular septa were present in 16 and 15 studies, respectively. Relevant laboratory findings included hypoalbuminemia in 14, elevated liver enzymes in 11, hypocholesterolemia in nine, and elevated LDH levels in six cases. In conclusion, radiologists should be familiar with the extrarenal imaging features of APN that may be seen on CT, and on ultrasonography as well, and should look for renal abnormalities to diagnose a clinically unsuspected APN. Alternatively, APN should be included in the differential diagnosis of systemic diseases that cause gallbladder wall thickening to avoid misdiagnosing it as acute cholecystitis.

Fever of unknown origin is alarming phenomenon in childhood. Diagnostic procedures should be focused on severe bacterial infection: pyelonephritis, pneumonia and other respiratory tract infections such as mastoiditis and sinusitis in particular ethmoiditis. The principles of treatment and diagnostics were discussed depending on age and general status of the child.

Brucellosis which is a endemic in Turkey, is a systemic infection which can affect any organ or system in the body. Since signs and symptoms of brucellosis resemble many other diseases, misdiagnosis and related increase in morbidity rate, are common. In this report, a case of brucellosis complicated with endocarditis, pyelonephritis, sacroileitis and thyroiditis, was presented. The case was a 32-years-old female patient in whom the diagnosis of brucellosis was delayed by 12 months since it was not taken into consideration during the clinical follow-up of the patient in various clinical centers. The patient was admitted to our center with the complaints of fever, headache, back pain, night sweats, fatigue, loss of appetite, weight loss, dysuria and polyuria. The patient had a history of consumption of raw milk and dairy products. Positive Brucella tube agglutination test (1/1280) and isolation of Brucella spp. in blood cultures led to the diagnosis of brucellosis. Sacroileitis was diagnosed upon pain on right hip joint movements, pain and restriction at the same joint in FABER test. The detection of vegetation during echocardiography, cardiac murmur during physical examination and the determination of increased ESR and CRP levels led to the diagnosis of endocarditis. Abdominal ultrasonography and urinalysis results (hematuria, proteinuria and pyuria) revealed pyelonephritis and increased free T3 and T4, decreased TSH and positive anti-thyroid autoantibodies (anti-TG, anti-TPO) revealed thyroiditis. Treatment was started with combination of rifampisin (1 x 600 mg/day) and doxycycline (2 x 100 mg/day). After the diagnosis of endocarditis, trimethoprim-sulfamethoxazole (3 x 960 mg/day) and streptomycin (1 x 1 g/day) were added to the treatment. Valve replacement surgery was planned, however, the patient didn't accept surgical intervention and antimicrobial treatment continued with streptomycin for 21 days and other antibiotics for six months. The patient exhibited significant improvement after the medical treatment. Although sacroileitis is a frequent complication of brucellosis, endocarditis, thyroiditis and pyelonephritis are among the rare complications. In cases of brucellosis with multiorgan involvement including endocarditis, successful results may be achieved by aggressive antimicrobial treatment. In endemic areas, brucellosis should always be taken into consideration in patients with fever of unknown origin and multisystem involvement.
