A rare presentation of neurocysticercosis in a young child.

Neurocysticercosis is the most common parasitic infestation of the central nervous system which manifests commonly as acute onset focal seizures. We report a rare clinical presentation of neurocysticercosis in a 1-year-old infant who presented with involuntary movements. Involuntary movements are not a common manifestation. Young children are rarely affected by this disease. In endemic areas, when a child presents with seizures or unusual neurological features and the CT scan shows contrast enhancing lesions or cystic lesions neurocysticercosis should be considered however young the child may be.

Differentiation of Asian rice gall midge, Orseolia oryzae (Wood-Mason), biotypes by sequence characterized amplified regions (SCARs).

We developed a polymerase chain reaction (PCR)-based assay that distinguished five different biotypes of the Asian gall midge (Orseolia oryzae), a major insect pest of rice. A total of 400 random primers were screened using random amplified polymorphic DNAs (RAPDs). Five diagnostic PCR products were isolated, cloned, sequenced and converted to sequence characterized amplified regions (SCARs). Primers specific to these SCARs were able to amplify specific DNA fragments from genomic DNAs of five biotypes of gall midge in a multiplexed-PCR-based assay. The amplified DNA fragments were used as diagnostic markers to identify different biotypes of gall midge. The SCAR primers were also capable of differentiating the Asian from the African rice gall midge (Orseolia oryzivora) as well as detecting a variant of biotype 5 which caused an outbreak in Kerala, India. Unlike the use of plant host differentials and midge feeding behaviour for identifying biotypes, this assay is fast, reliable and unaffected by environmental factors.

X-chromosome abnormalities in women with premature ovarian failure.

OBJECTIVE: To evaluate the significance of X-chromosome abnormalities identified in a series of women with premature ovarian failure (POF). STUDY DESIGN: Karyotypes were reviewed for all women referred to our cytogenetic laboratory over a five-year interval with the diagnosis of POF. Thirty women aged less than 40 with unexplained secondary amenorrhea and elevated follicle-stimulating hormone were included. RESULTS: Of the 30 patients, 26 had a normal karyotype and 4 showed the following X-chromosome abnormalities: 46,Xi(Xq), 45,X/46,XX mosaic, 46,X,der(X)t(X;Y)(q28;q12) mat and 46,X,t(X;5)(q22;q11.2) mat. In the two families with familial translocations, carrier females within each family showed considerable variability in age at onset of menopause. CONCLUSION: Both familial and nonfamilial X-chromosome abnormalities can be identified in women with POF. Cytogenetic studies should not be limited to those patients with very-early-onset POF.

Distillery effluent treatment using Artemia.

Artemia functions as living filter for the secondary treatment of distillery effluent, which reduces up to 69% of the total solids and 33.34% of BOD in the saline medium of 60 ppt. Chemical analysis of diluted effluent after treatment with Artemia showed a significant (P less than 0.001) decrease in the electrical conductivity, calcium and potassium values. However, an increase in sodium concentration and pH values, was recorded during experiment.

Marfan syndrome is closely linked to a marker on chromosome 15q1.5----q2.1.

Marfan syndrome is a systemic disorder of the connective tissue inherited as an autosomal dominant trait. The disorder imparts significant morbidity and mortality. The etiology of the disorder remains elusive. A recent study localized the gene for Marfan syndrome on chromosome 15. We present data showing that marker D15S48 is genetically linked to Marfan syndrome. Pairwise linkage analysis gave a maximum lod (logarithm of odds) score of Z = 11.78 at theta = 0.02. Furthermore our data suggest that the Marfan syndrome locus is possibly flanked on either side by D15S48 and D15S49.
