“SETTING: Tuberculous meningitis (TBM)


“SETTING: Tuberculous meningitis (TBM) 10058-F4 datasheet is a severe complication of tuberculosis (TB) predominantly affecting young children. Early initiation of treatment is important to prevent morbidity and mortality

associated with TBM, emphasising the importance of early diagnosis. Among the most promising new methods for diagnosing TB are antigen-detection assays based on the detection of lipoarabinomannan (LAM).

OBJECTIVE: To evaluate the diagnostic value of a commercial, antigen-capture enzyme-linked immunosorbent assay (ELISA) test based on the detection of LAM in urine for the early diagnosis of TBM in children.

METHOD: A cross-sectional study in which urine samples from paediatric patients with suspected TBM attending the Tygerberg Children’s Hospital, Cape Town, South Africa, were tested for LAM.

RESULTS: Complete data were available for 50 of 56 patients with suspected selleck chemicals TBM. TBM was diagnosed

in 21 (42%) patients and excluded in 29 (58%). The LAM ELISA had a sensitivity of 4.8% and a specificity of 93.1%. Serial measurements in the first 2 weeks after treatment initiation did not improve test performance.

CONCLUSION: We have shown that urinary LAM detection was of little value for the diagnosis of TBM in a cohort of paediatric patients with suspected TBM.”
“Background: Genotype-phenotype correlations for chromosomal imbalances are often limited by overlapping effects of partial trisomy Captisol chemical structure and monosomy resulting from unbalanced translocations and by poor resolution of banding analysis for breakpoint designation. Here we report the clinical features of isolated

partial trisomy 7q21.2 to 7q31.31 without overlapping phenotypic effects of partial monosomy in an 8 years old girl. The breakpoints of the unbalanced rearranged chromosome 7 could be defined precisely by array-CGH and a further imbalance could be excluded. The breakpoints of the balanced rearranged chromosomes 9 and 10 were identified by microdissection of fluorescence labelled derivative chromosomes 9 and 10.

Results: The proband’s mother showed a complex balanced translocation t(9;10)(p13;q23) with insertion of 7q21.2-31.31 at the translocation breakpoint at 9p13. The daughter inherited the rearranged chromosomes 9 and 10 but the normal chromosome 7 from her mother, resulting in partial trisomy 7q21.2 to 7q31.31. The phenotype of the patient consisted of marked developmental retardation, facial dysmorphism, short stature, strabism, and hyperextensible metacarpophalangeal joints.

Discussion: For better understanding of genotype-phenotype correlation a new classification of 7q duplications which will be based on findings of molecular karyotyping is needed. Therefore, the description of well-defined patients is valuable. This case shows that FISH-microdissection is of great benefit for precise breakpoint designation in balanced rearrangements.
