ABSTRACT
Aim: To study the clinico-etiological profile of children with thrombocytopenia. Methods: This prospective hospital-based study included all children (<18 years) with thrombocytopenia at the time of hospitalization and/or thrombocytopenia during the course of their hospital stay. A detailed history was recorded and appropriate laboratory investigations were carried out. Results: The study group comprised 246 children (mean age, 9.29 years; median age, 10 years) with male to female ratio of 1.5:1. Nearly 45% of children were above 10 years of age. Trends of admissions showed that the majority of children with thrombocytopenia (n = 115) got hospitalized during the rainy season, followed by summer (n = 84). Fever (72.8%), pallor (52.8%), bleeding manifestations (22%), lymphadenopathy (20.3%), and splenomegaly (20.3%) were common clinical features. Petechiae was the most common bleeding manifestation (63%). Septicemia (24%) was the most common etiology, followed by megaloblastic anemia (14.6%), undiagnosed fever (10.2%), local infection (9.3%), hepatitis (6.5%), and scrub typhus (6.1%). About nine children died. All those who died had septicemia and multi-organ dysfunction (MOD). On logistic regression analysis, age >10 years, presence of bleeding, arthralgia, rash, pallor, gastrointestinal (GI) symptoms, hematological disorders, and malignancy were associated with severe thrombocytopenia. Conclusion: Thrombocytopenia is a common hematological observation. This study revealed seasonal variation in the occurrence of thrombocytopenia in children, with the maximum number of cases in the rainy season. Septicemia is the commonest etiology. The majority of children with thrombocytopenia have no bleeding manifestations. Age >10 years, presence of bleeding, arthralgia, rash, pallor, GI symptoms, hematological disorders, and malignancy are associated with severe thrombocytopenia.
ABSTRACT
Three study sites along the roads with different automobile traffic densities were selected and cattle milk samples were collected every month from all the three sites. Lead concentration in samples were determined through atomic absorption spectrometer. Milk collected from area of heavy traffic contained 4.6-7.2 ppm of Pb, which is much higher than its permissible limit (0.3 ppm) according to FDA.

A 57 year old male presented with episodic behavioural abnormalities and loss of consciousness for 2 years. His fasting blood glucose was 20 mg/dl and corresponding insulin level 119 uU/ml. His EEG showed intermittent rhythmic delta activity. Abdominal CT scan revealed an enhancing mass in the tail of the pancreas and secondaries in the liver. After distal pancreatectomy, resection of the left lobe of the liver and chemotherapy, the hypoglycaemic spells subsided. Histopathology revealed an islet cell tumour with metastases in the liver. Episodic neurobehavioural dysfunction should alert towards the possibility of hypoglycaemia.

The activity of isocitrate lyase (EC 4.1.3.1) in the cotyledons of germinating soybean is controlled by the embryonic axis. Plant growth regulators like gibberellic acid, indole acetic acid and 2,4 dichlorophenoxy acetic acid are able to increase the enzyme activity in cotyledons of whole seedlings but not in dissected cotyledons. The control of induction of the enzyme activity during germination by the embryo could be mediated by the elaboration of kinetin.
