Salmonella typhi infections. A 10-year retrospective study.

Enteric fever is still a common health problem in many countries, especially in children. Thus a ten-year retrospective study was carried out to evaluate the clinical and laboratory properties of enteric fever and the incidence of antimicrobial resistance in children. Throughout the past 10 years, Salmonella was isolated in 105 patients by blood culturing, 27 of which were Salmonella typhi. Most of the patients were above the age of two. Besides the typical symptoms and signs of enteric fever, 29.2% of the patients had some neurologic findings. Besides, 68.5% had elevated liver enzymes while only 44.4% had hepatomegaly with or without splenomegaly. Anemia was present in 44%, leukopenia in 16% and leukocytosis in 11.1% of the cases. The emergence of antimicrobial resistance during the last five years against ampicillin, chloramphenicol and trimetoprim-sulfamethoxazole has created a challenge in treating these infections.

Splenic abscess due to brucella in childhood. A case report.

An eleven-year-old male was diagnosed with multiple splenic abscesses due to brucella. He was treated only with antibiotics. Although splenic abscess is very rare in childhood, in febrile patients with upper quadrant abdominal pain, tenderness and splenomegaly, splenic abscess should be suspected especially in epidemic regions. Diagnosis can be confirmed by ultrasonography and computerized tomography.

Systemic lupus erythematosus presenting with thrombocytopenia. Report of a child with positive anticardiolipin antibodies.

We report a case of systemic lupus erythematosus initially presenting with thrombocytopenia and diagnosed as immune thrombocytopenic purpura. The patient subsequently developed lymphadenopathy, arthritis and cardiac involvement along with anticardiolipin antibodies. We would like to emphasize the fact that these autoantibodies have a role in the pathogenesis of thrombocyte destruction, and that patients with immune thrombocytopenic purpura should be followed for signs of systemic lupus erythematosus.

Multiple intracranial tuberculomas in a child.

Intracranial tuberculomas continue to be a serious complication of central nervous system tuberculosis. Tuberculomas are conglomerates of tubercles resulting from hematogenous spread of infection. Modern neuroimaging studies such as magnetic resonance imaging and molecular biologic techniques such as polymerase chain reaction are helpful in the diagnosis of central nervous system tuberculosis and tuberculomas. We report a boy with multiple intracranial tuberculomas diagnosed and treated with the aids of magnetic resonance and polymerase chain reaction techniques.

Diagnosis of childhood tuberculosis by polymerase chain reaction.

The polymerase chain reaction (PCR) using oligonucleotides based on the repetitive sequence (IS6110) of Mycobacterium tuberculosis as a primer was evaluated for detection of M.tuberculosis in clinical samples. We tested 55 clinical specimens from patients suspected of having tuberculosis and 71 specimens from control subjects. PCR was more sensitive than culture (positivity rate was 14.5% and 36.3%, respectively, in suspected patients). This approach to the diagnosis of tuberculosis is a valid diagnostic alternative to classical procedures.

Microorganisms involved in acute bacterial meningitis in children and the role of Haemophilus influenzae.

Acute bacterial meningitis (ABM) is an important cause of mortality and neurological damage in children. Documentation of the etiological agents is very important both for the treatment of patients and for prophylactic approaches. H.influenzae, N.meningitidis and S.pneumoniae are the three major pathogens involved in ABM. In Turkey for many years H.influenzae has not been isolated in cerebrospinal fluid (CSF) specimens. In order to show the bacteria involved in ABM in our hospital and to see the role of H.influenzae, we investigated the CSF of 59 patients with bacterial meningitis using Gram and Wayson stains, culture and latex agglutination techniques. The agents were determined in 38 (64.4%) specimens by using culture positivity in 30 (50.8%), and latex or stain positivity in eight (13.6%) specimens. The microorganisms causing ABM included S.pneumoniae (25.6%), gram-negative enteric bacillI (17.9%), N.meningitis (12.8%), alpha hemolytic streptococci (10.3%), H.influenzae (10.3%), nonfermentative gram-negative bacillI (5.1%), candida spp. (5.1%), group B streptococci (2.6%), coagulase negative staphylococci (2.6%), S.aureus (2.6%) and pseudomonas spp. (5.1%). In this study it has been shown that H.influenzae can cause ABM in Turkish children. Multicentric studies from different parts of Turkey will be helpful in showing the real incidence in our country.

Hepatic mucormycosis in a child with fulminant hepatic failure.

Mucormycosis is an uncommon, opportunistic infection in children. We present a case of fulminant hepatic failure with hepatic mucormycosis. Although the suggested defects and pathogenic mechanisms in infections related to hepatic failure and mucormycosis are similar, few cases with both mucormycosis and liver failure have been reported.

Tumor necrosis factor-alpha and interleukin-1 beta levels in children with bacterial, tuberculous and aseptic meningitis.

Cerebrospinal fluid levels of tumor necrosis factor-alpha and interleukin-1 beta in 78 children with nonbacterial, bacterial and tuberculous meningitis, and in 34 control subjects were analyzed in order to evaluate the involvement of these cytokines in the pathogenesis of acute bacterial meningitis and their discriminative value between different etiologies of meningitis. Tumor necrosis factor-alpha and interleukin-1 beta levels were significantly higher in bacterial and tuberculous meningitis than in aseptic meningitis and in control subjects (p < 0.0001). There was no difference in the levels of tumor necrosis factor-alpha and interleukin-1 beta between nonbacterial meningitis and control groups. The finding that both tumor necrosis factor-alpha and interleukin-1 beta are increased in the cerebrospinal fluid of patients with bacterial and tuberculous meningitis whereas normal levels of these two cytokines have been found in patients with nonbacterial meningitis signifies that these cytokines may be used to differentiate between bacterial and nonbacterial meningitis.
