Complications of varicella requiring hospitalization in immunocompetent children are more frequent than previously thought.

Purpose In this study we aimed to evaluate the postnatally screened karyotype results in couples who were referred because of primary infertility between 2000 and 2006 in Izmir. Methods The records of a total of 179 cases were evaluated retrospectively. Results A total of 21 cases (11.74%) showed chromosomal alteration. Thirteen (7.26%) were 47,XXY; three (1.68%) were pericentric inversion of chromosome 9; one (0.56%) 46,XY/45,XO; one (0.56%) 46,XY/47,XXY/48,XXXY; one (0.56%) 46,XY,t(X;1); one (0.56%) 46,XY/46,XY,del (Y)(q11.2) and one (0.56%) 46,XX. ConclusionsThe rate of gonosomal chromosomal abnormalities was nearly three times higher in our region than the rate in the literature. Chromosomal analysis is strongly suggested particularly in those who suffer fertility problems.

Mannose-binding lectin (MBL) plays an important role in innate immunity mediating phagocytosis and activating the MBL complement pathway. Few studies, conducted in adult populations, have shown that genetically determined low MBL levels may confer partial protection against tuberculosis (TB). In this study we aimed to investigate the relationships between the susceptibility to TB and two low producing MBL2 gene polymorphisms (codons 54 and 57) and MBL levels in children. Forty-four TB children (27 pulmonary TB, 17 extrapulmonary TB) and 99 age-matched healthy control children were included in the study. The mean age in the study group was 7.02 +/- 4.5 years. Genotyping of the MBL2 gene for codon 54 and 57 polymorphisms was carried out, and MBL levels in serum were also detected in all subjects from both groups. None of the subjects from either group showed codon 57 polymorphisms. The frequency of the AB genotype which produces low level MBL is significantly lower in the patients (9.1%) compared to control subjects (27.3%) (p < 0.011). The difference was especially significant between the extrapulmonary group and healthy controls (p < 0.006). The BB genotype was observed in only one child from the healthy controls and no children from the patient group. The median MBL plasma concentration was also significantly lower in the control group than that found in the study group (p = 0.036). These results indicate that low levels of MBL and AB genotype may be involved in the protection against tuberculosis, especially extrapulmonary tuberculosis in children.

The most common cause of fever of unknown origin remains infection. The proportion of collagen tissue disorders and neoplasia have been found to be decreased. Unusual reasons such as diabetes insipidus and foreign body in the respiratory system in the miscellaneous group have been detected. Age plays important role in the diagnosis of prolonged fever, while some basic laboratory tests might give clues in the evaluation and may suggest a diagnosis.
