Fever of unknown origin: a review of 20 patients with adult-onset Still's disease.

Abstract In this study we aimed to investigate the findings in patients with adult-onset Stills disease (AOSD) admitted with fever of unknown origin (FUO) during the last 18 years in our unit, in order to discover the ratio of such patients to all patients with FUO during the same period, and to determine the clinical features of AOSD in FUO. The number and the aetiologies of the patients with FUO diagnosed between 1984 and 2001, and the clinical features of those with AOSD, were taken from the patient files. The diagnosis of AOSD was reanalysed according to the diagnostic criteria of Cush et al. [11]. The presumed diagnoses before a diagnosis of AOSD was established were also noted. The χ2 and Fishers exact tests were used for statistical analysis. We studied 130 patients with a diagnosis of FUO, 36 (28%) of whom had collagen vascular diseases. Of these 36 patients, 20 (56%, 12 female, 8 male, mean age 34 years, range 16–65) had AOSD. Clinical and laboratory findings were as follows: fever (100%), arthralgia (90%), rash (85%), sore throat (75%), arthritis (65%), myalgia (60%), splenomegaly (40%), hepatomegaly (25%), lymphadenopathy (15%), anaemia (65%), neutrophilic leukocytosis (90%), increased erythrocyte sedimentation rate (100%), elevated transaminase levels (65%), a negative RF (100%), and a negative FANA (80%). Antibiotics had been prescribed in 18 (90%) of cases. The presumed infectious diagnoses were streptococcal tonsillitis/pharyngitis (50%), infective endocarditis (four patients), sepsis (two patients) and acute bacterial meningitis (two patients). The presumed non-infectious diagnoses were acute rheumatic fever (three patients), seronegative rheumatoid arthritis (two patients) and polymyositis (two patients). Sixteen patients were followed for a mean duration of 30 months (range 2–59). A remission was obtained with indomethacin in three cases (19%), and with prednisolone in the remainder. Relapse was detected in three cases (19%). AOSD is one of the most frequent aetiologies of FUO. During the diagnostic course of a patient with FUO, a maculopapular rash and/or arthralgia and/or sore throat should raise the suspicion of AOSD. Because the disease has heterogeneous clinical findings, certain bacterial infections (e.g. streptococcal pharyngitis and sepsis) are generally considered and the prescribing of antibiotics is common.

Fever of unknown origin in Turkey

Abstract.Background:The etiology of fever of unknown origin (FUO) includes primarily infectious, collagen-vascular and neoplastic diseases. The distribution of the disorders causing FUO may differ according to the geographic area and the socioeconomical status of the country. Moreover, the developments in radiographic and microbiologic methods have changed the spectrum of diseases causing FUO.Materials and Methods:We reviewed 117 cases that fulfilled the criteria of FUO followed in our department during the period 1984 to 2001.Results:The etiology of FUO was infectious diseases in 34% of the patients, collagen-vascular diseases in 23%, neoplasms in 19% and miscellaneous diseases in 10%. In 14% of the cases the etiology could not be found. The three leading diseases were tuberculosis (24%), lymphomas (19%) and adult-onset Still’s disease (11%). Tuberculosis was found to be a more common cause of FUO than reported in studies in developed countries. Invasive procedures helped to establish the diagnosis in 50 out of 92 patients (43%). As a final diagnostic procedure, laparotomy aided the establishment of a diagnosis in 15 out of 20 patients (75%).Conclusion:Although the relative rate of infectious disease as etiologic category is less commonly encountered, infectious disease, especially tuberculosis, remains a common cause of FUO. Although several diseases may lead to FUO, lymphomas, adult-onset Still’s disease and particularly tuberculosis should be considered in the differential diagnosis of a patient admitted with FUO.

Tuberculous lymphadenopathy in adults: a review of 35 cases.

Abstract We retrospectively reviewed clinical, diagnostic, therapeutic and prognostic features of 35 patients (25 female, 10 male, mean age: 33 years, range: 16–70) with tuberculous lymphadenopathy (TB LAP) which had been followed since 1980. The diagnosis was established by tissue sampling in 32 cases (caseating granulomatous adenitis in 89%) or presence of acid-fast bacilli (AFB) in the aspirate in 2 cases and in the drainage in 1 case. Paraffin-embedded granulomatous tissues were stained by Ehrlich-Ziehl-Neelsen (EZN) and also Mycobacterium tuberculosis DNA was studied by polymerase chain reaction (PCR) (n = 21). The patients were admitted with enlarging LAP (34%), draining LAP (9%), and both systemic complaints and enlarging LAP (57%). Cervical lymph nodes were the most frequently involved site (77%). Pathologic findings on chest X-ray were seen in 23%. Erythrocyte sedimentation rate (ESR) was higher than 100 mm/hour in 25% and associated with systemic complaints. Tuberculin skin test was positive in 91%. AFB could not be seen in any granulomatous tissue (n: 21), but PCR study was positive in 33% (7/21). All patients were given anti-TB treatment (INH, RMP, EMB and/or PZA). Surgical excision of draining LAP with surrounding inflammatory tissues in addition to the medical treatment was needed in 2 cases. Clinical improvement was obtained within 3 months of the treatment and ESR returned to normal within 5 months. After completion of the treatment, 22 patients were followed-up; mean duration was 3 years, and none relapsed. In conclusion, a patient with TB LAP generally presents with a few small, painless, cervical lymph nodes, which are slowly enlarging. For exact diagnosis, excisional biopsy for histologic and microbiologic studies is essential. Use of anti-TB drugs is the main therapeutic option.

Losartan-induced hepatic injury.

Losartan, an angiotensin II receptor antagonist, is widely used for the treatment of hypertension. Clinical experience with this drug has demonstrated that it is safe. Losartan-induced hepatic toxicity is extremely rare. We report a case of severe hepatic toxicity and fibrosis caused by losartan use, and we review four previously reported cases. Drug-induced hepatic injury may be seen during the treatment of hypertension by losartan and the clinician should be aware of this toxicity, especially during the initial phase of treatment.

The diagnosis of brucellosis by use of BACTEC 9240 blood culture system

The diagnosis of brucellosis is generally made when a standard tube agglutination titer of 1/160 or more for anti-Brucella antibodies in the presence of compatible clinical signs and symptoms. However isolation of the organism from blood or bone marrow is the proof of the disease. In this study we aimed to describe the rate and duration of isolation of Brucella spp. from blood and bone marrow by use of automated blood culture system (BACTEC 9240). Between 1997 to 2001, 23 adults were diagnosed as brucellosis. Blood culture was obtained in all and simultaneous bone marrow culture in 18 and both specimens were cultured by BACTEC 9240. Brucella was isolated from blood and bone marrow cultures in 19 (82.6%) and 13 (81.2%) respectively. All positive blood cultures yielded within 7 days and bone marrow cultures in 4 days. We concluded that automated BACTEC culture systems can isolate Brucella spp. in a fast and efficient way.

Tuberculous Subcutaneous Abscesses Developing During Miliary Tuberculosis Therapy

Although rare, paradoxical subcutaneous abscesses may develop during appropriate treatment of miliary tuberculosis. While the pathogenesis of this phenomenon is not clear, some theories have been postulated. A case of a 37-y-old woman diagnosed as having miliary tuberculosis who developed subcutaneous abscesses within the 5 months of antiberculous treatment is described and all 6 similar cases published in English from 1954 to 1999 are discussed.Although rare, paradoxical subcutaneous abscesses may develop during appropriate treatment of miliary tuberculosis.

A Case of Cervical Brucella spondylitis with Paravertebral Abscess and Neurological Deficits

Spondylitis is one of the more frequent osteoarticular complications of Brucella infection, but cervical spine involvement is rare. We report here a case of cervical Brucella spondylitis with paravertebral anterior epidural abscess which resulted in neurological deficits. The diagnosis is based on clinical history supported by Brucella serology, radiological findings and histological evidence.

Prolonged Fever Caused by Parvovirus B19—Induced Meningitis: Case Report and Review

woman was treated with doxycycline (200 mg/d). Three days later, she became afebrile and since then has remained well. Acute pancreatitis is usually a sterile inflammatory process mostly associated with alcoholism, trauma, metabolic abnormalities, and biliary or gastrointestinal diseases. About one-third of cases remain idiopathic [2, 3]. It is generally accepted that parasites (Ascaris lumbricoides and Opisthorchis sinensis) and viral agents, including mumps virus, Coxsackie B viruses, Epstein-Barr virus, and herpes simplex virus, can cause acute pancreatitis [2, 3]. Bacterial pathogens, such as Campylobacter fetus, Mycobacterium tuberculosis, T. pallidum, Leptospira species, L. pneumophila, Salmonella species, and Y. enterocolitica, have previously been reported to cause acute pancreatitis [2, 3]. Q fever, a zoonosis due to the obligate intracellular bacterium C. burnetii, may be acute or chronic. Acute Q fever presents generally as a self-limited acute febrile illness associated with atypical pneumonia or hepatitis [4, 5]. Both the shepherdess and her husband were probably infected during the delivery of the kid by inhalation of contaminated aerosols generated from the heavily infected placenta (the major mechanism whereby Q fever is transmitted to humans) [6]. Whether her husband presented with a clinical picture suggestive of acute Q fever, the shepherdess had “query” acute pancreatitis. To our knowledge, this is the first case report indicating that acute Q fever may present as acute pancreatitis. C. burnetii should be added to the list of microorganisms capable of inducing acute pancreatitis since Q fever requires specific antibiotic treatment. Moreover, systematic screening for Q fever may explain some of the idiopathic cases of acute pancreatitis.

Epileptic seizure: an atypical presentation in an adolescent boy with neurobrucellosis.

Brucellosis is an infectious disease with multisystemic involvement caused by the genus Brucella. Neurological complications, including meningitis, meningoencephalitis, myelitis-radiculoneuritis, brain abscess, epidural abscess and meningovascular syndromes, are rarely encountered. We present a patient with epileptic seizures and aggressive mood due to chronic neurobrucellosis of 2.5 y duration, which was misdiagnosed as bacterial meningitis and epilepsy. This form of presentation has not previously been reported in the English language literature. We conclude that the diagnosis of neurobrucellosis should be considered in patients presenting with recurrent or chronic meningitis syndromes with or without seizure from endemic areas for brucellosis.
