Comparative study on the effect of chemicals on Alternaria blight in Indian mustard - A multi-location study in India.

High severity of Alternaria blight disease is a major constraint in production of rapeseed-mustard in India. The aim of this study was to investigate the suppressive potential of chemicals viz., zinc sulphate, borax, sulphur, potash and calcium sulphate, aqueous extracts viz., Eucalyptus globosus (50 g l-1) leaf extract and garlic (Allium sativum) bulb (20 g l-1) extract, cow urine and bio-agents Trichoderma harzianum, Pseudomonas fluorescence in comparison with the recommended chemical fungicide (mancozeb), against foliar disease Alternaria blight of Indian mustard [Brassica juncea (L.) Czern. and Coss] under five different geographical locations of India. Mancozeb recorded the lowest mean severity (leaf: 33.1%; pod: 26.3%) of Alternaria blight with efficacy of garlic bulb extract alone (leaf = 34.4%; pod = 27.3%) or in combination with cow urine (leaf = 34.2%; pod = 28.6%) being statistically at par with the recommended chemical fungicide. Chemicals also proved effective in reducing Alternaria blight severity on leaves and pods of Indian mustard (leaf = 36.3- 37.9%; pod = 27.5-30.1%). The effective treatments besides providing significant reduction in disease severity also enabled increase in dry seed yield of the crop (mancozeb = 2052 kg ha-1; garlic = 2006 kg ha-1; control = 1561 kg ha-1).

Severe haematoma of the vulva--a report of two cases and a clinical review.

Haematoma of the vulva may occur following blunt trauma due to its highly vascular structure. We present two cases of haematoma of the vulva caused by domestic violence, following a kick on the perineum and falling astride on the perineum. Evacuation of the haematoma and repair of lacerated tissues were successfully performed.

Pedunculated angiomyxoma of the vulva - a rare clinical entity.

BACKGROUND: Aggressive angiomyxoma is an uncommon mesenchymal tumor that preferentially involves the pelvic and perineal regions of females. Since its initial description in 1983, approximately 65 cases have been reported in the English literature. CASE: A 33-year-old parous woman with a slow growing pedunculated soft tissue tumour of the vulva which later underwent surface ulceration. Pathological findings in the case were suggestive of an aggressive angiomyxoma, a distinctive soft tissue non-malignant tumour, which could, at times be locally aggressive.

Brainstem auditory evoked responses in primary hypertension.

Brainstem auditory evoked potential responses (BAEPs) were recorded from CZ-A1 and CZ-A2 scalp regions in 23 hypertensive and 14 normotensive subjects. Hypertension was graded depending upon the extent of raised blood pressure. BAEPs in patients of grade I and II hypertension did not show any change when compared to normotensive subjects. However, grade III hypertensive case showed significant prolongation of absolute peak latencies of wave I, II, V and interpeak latency of wave III-V indicating involvement of brainstem auditory pathways. Multiple regression analysis revealed significant correlation of rise in systolic and diastolic blood pressure with absolute peak latencies of BAEPs in hypertensive patients.

Extrapyramidal syndrome in falciparum malaria.

Three unusual cases of falciparum malaria with extrapyramidal syndrome are reported. Two of these cases had extrapyramidal features at admission and the other one developed them after quinine therapy.
