The evaluation of vaccination against measles at nine months of age (report of an epidemic).

Sixteen measles cases were studied during an epidemic that broke out in Etimesgut district of Ankara. Eight of these children had never been vaccinated against measles while the remainder had been vaccinated at nine months of age. In the sera obtained during the course of the illness, anti-measles antibody was not detectable in six vaccinated children and in four unvaccinated children. Upon observing the siblings of the subjects, it was determined that one out of three who had not been vaccinated against measles and three out of seven who had been vaccinated at nine months of age contracted the disease within a month. However none of the siblings who had been vaccinated against measles at 15 months contracted the disease. In our cases, although vaccination at nine months of age could not prevent measles, it resulted in a milder form of the disease. It seems that measles vaccine administered to infants at around nine months of age does not prevent the occurrence of the disease in many children.

Elimination of maternal antibodies against measles (is the policy of vaccinating children younger than nine months of age suitable for Turkey?).

Maternal antibodies against measles in 223 healthy children aged 22 to 31 weeks were studied. The ratio of children with detectable antibodies declined from 61.4 percent at 22-23 weeks of age to 20 percent at 26-27 weeks of age. Since the minimum proportion of antibody-positive children (15.6% at 26-27 weeks of age) is still higher than the optimum proportion (5%), the Schwarz vaccine which is used mostly in measles immunization seems not to be effective to obtain a high seroconversion rate in our infants. We suggest that the Edmonston-Zagreb strain of measles vaccine be used for infants under 9 months of age in Turkey.

Serological evaluation of 52 children immunized with the combined measles, mumps and rubella vaccine.

Fifty-two of 298 children vaccinated with the measles-mumps-rubella (MMR) vaccine at around the age of 16 months were evaluated for antibody titres against measles, mumps, and rubella. The seropositivity rates for measles, mumps, and rubella were 86%, 92%, and 98%, respectively. While the most prominent side effects were irritability (6.04%) and fever (4.69%), 83.55% of the vaccinated children showed no undesirable reaction to the vaccine. The MMR vaccine appeared to be immunogenic and nonreactogenic for the children in the study.

Prognostic factors in Salmonella typhimurium septicemia. A 10-year retrospective study.

In this study, 74 S.typhimurium septicemia cases were evaluated retrospectively from their records, and the age and sex distribution, presence of underlying disease, signs and symptoms, complete blood count, liver function tests and case fatality rate were documented and prognostic factors determined. It has been shown that S.typhimurium is the most common strain causing Salmonella septicemia, which is more fatal in the newborn period and in the presence of an associated disease, while hemoglobin and leukocyte counts do not play an important role in the prognosis. In Salmonella septicemia, congenital heart disease was the second-most common associated disease, which may be attributed to probable underlying immunodeficiency.

Mucormycosis in a diabetic child and its treatment with fluconazole: a case report.

We present here a case of a diabetic patient having complaints of painful swelling of the left eye, blurring of the vision and tonic-clonic convulsion. Surgical exploration of the sinuses was performed, and the histopathological examination revealed mucomycosis. Because of the side effects of Amphotericin B, we tried Fluconazole and the patient recovered completely.

Typhoid fever with very high transaminase levels.

Typhoid fever is endemic in developing countries and may cause very different clinical findings. Although hepatic involvement and abnormal liver function tests may be seen in 50% of the patients, intravascular hemolysis and renal involvement are rare. In this report, a 10-year-old patient with enteric fever presenting with hepatitis, severe intravascular hemolysis and glomerulonephritis is presented. To see all of these findings together in a patient with typhoid fever is very rare and may cause diagnostic difficulties.

Cardiac arrest: an unusual side-effect of intravenous ornidazole.

Nitroimidazoles have been used alone or in combination with other antibacterial agents in the treatment of brain abscess. They are associated with certain adverse reactions related primarily to the gastrointestinal tract and central nervous system. But, as far as we know, cardiac arrest due to ornidazole has not been reported in the literature. In this study, we presented a case in which cardiac arrest occurred as an unusual side-effect of intravenous ornidazole administered to a ten-year-old girl suffering from brain abscess.

Comparative therapeutic results of penicillin plus chloramphenicol versus ampicillin plus sulbactam in childhood meningococcemia.

Fifty-seven cases of meningococcemia were evaluated retrospectively. The age of the patients ranged between 2 and 17 years. Of the 57 patients investigated for the efficacy of antibiotic treatment, 31 (54.4%) were treated with benzylpenicillin plus chloramphenicol and 26 (45.6%) with ampicillin plus sulbactam. Patients with criteria for a poor prognosis (presence of disseminated intravascular coagulation, low arterial blood pressure, and altered consciousness) were divided equally into two treatment groups. There were no statistically significant differences between the two treatment groups except for the higher incidence of convulsion in the group given penicillin plus chloramphenicol. The mortality rate was 19.3 percent for patients treated with benzylpenicillin plus chloramphenicol and 7.6 percent for patients treated with ampicillin plus sulbactam (p = 0.19; overall mortality rate 14%).

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.
