Central nervous system brucellosis: presentation, diagnosis and treatment.

Although neurological symptoms in brucellosis are frequent, central nervous system (CNS) involvement is uncommon. Five patients with neurobrucellosis are presented. Three patients presented with meningoencephalitis, one with polyradiculoneuritis and one with myelitis and an eighth nerve palsy. All patients had lymphocytic pleocytosis, low glucose and elevated levels of protein in the cerebrospinal fluid (CSF). Gamma-globulin and IgG values in the CSF were also increased. Results of agglutination tests for Brucella in serum and CSF were positive for all patients, although titres were less in the CSF. Brucella melitensis was cultured from two patients. Treatment included concurrent administration of three of the following drugs: doxycycline, rifampicin, streptomycin, co-trimoxazole, ceftriaxone or ciprofloxacin. The three patients with meningoencephalitis fully recovered; the other two patients were left with minor disability.

Hematological manifestations in brucellosis cases in Turkey.

The hematological findings of 233 patients with brucellosis are presented and the possible pathologies discussed. Anemia was present in 128 patients (55%), leukopenia in 49 (21%) and thrombocytopenia in 59 (26%). Bone marrow aspirates of 18 patients (8%) with pancytopenia were examined. The bone marrow was hypercellular in 15 and normocellular in 3 patients. Granulomatous lesions were detected in 12 cases (67%), and slight to moderate cytophagocytosis of erythrocytes, granulocytes and platelets existed in all patients. Blood cell counts reverted to normal within 2-3 weeks of initiating chemotherapy with recovery from the disease.

Nucleotide sequence of gene 6 of avian-like group A rotavirus 993/83.

Two cDNA clones, which hybridized in Northern blots to RNA segment 6 of the homologous avian-like group A rotavirus (RV) 993/83 and pigeon RV PO-13, but not to mammalian group A rotaviruses, were sequenced. The gene 6 sequence contained a single long open reading frame encoding a protein of 397 amino acids (total MW 44,460). Comparison of the deduced amino acid sequence with VP6 protein from mammalian group A RV revealed 72 to 74.3% of amino acid identity. These values are surprisingly low in view of the high homology levels described up to now for group A RV. Avian-like RV 993/83 is however not a missing link between group A and C RV as it is as distantly related to group C RV as group A mammalian RV to group C RV. The evolutionary implications of these observations are briefly discussed.

[HIV infections among Turkish citizens who have lived in foreign countries].

AIDS or HIV infection, since 1981 when the first description was made because of showing epidemic characteristics, present increasing in number of patients, go along with high mortality, the disease become an event not only medically but also for any parts of the society. There is a danger of AIDS in risky groups and also danger of spreading by those persons. Among the 10985 Turkish citizens who came Turkey from foreign countries to fulfill military duty, antibody research against HIV was made and one positive anti-HIV case was observed.

[Lyme disease].

Lyme disease, which is caused by the tick-borne spirochete Borrelia burgdorferi, usually begins with a characteristic skin lesion erythema chronicum migrans (ECM), that may be followed by neurological or cardiac abnormalities and is accompanied by malaise, fatigue, fever, myalgia, headache, lymphadenopathy and is often followed by arthritis. The disease takes its name from Lyme, Connecticut, where the full spectrum of illness was first described in 1975. It is known to be a multisystemic infectious disease. Because culture and direct visualisation of spirochetes are often negative in Lyme disease, serological testing has been the only practical laboratory aid in diagnosis and primarily clinical findings.

[Viral encephalitis].

Acute viral and other infectious causes of encephalitis usually produce fever, headache, stiff neck and alterations in consciousness, focal neurologic signs and seizures. A large number of viral and nonviral agents can cause encephalitis. Arthropod-borne viruses peak in summer, the tick-borne infections occur in early summer, enterovirus infections in later summer and mumps in the winter and spring.
