Contrary to this belief, classical diphtheria continues to exist in many parts of India despite extensive immunizations campaigns raising the suspicion of resurgence. The absence of essential drugs in treatment of this condition has further worsened the situation. The expenditure involved in procuring these drugs is yet another constraint. We here by present one such case of adult diphtheria and discuss the problems associated with its diagnosis and treatment.

It is not yet established that both conditions are determinants of psychomotor development. The study investigated whether or not low birth weight leads to delayed psychomotor development of a child, and whether it can be mitigated by adequate postnatal growth. A cross-sectional study was conducted in 2002 in 15 rural and 11 urban communities of Sindh province, Pakistan. Assessment of 1234 children less than 3 years of age included Bayley's Scale of Infant Development II, socioeconomic questionnaire and anthropometry; WHO standards were used to calculate z-scores of height-for-age, weight-for-height and weight-for-age. The underlying study hypotheses were tested through multiple regression modelling. Out of 1219 children, 283 (23.2%) had delayed psychomotor development and 639 (52.4%) were undernourished according to the composite index of anthropometric failure. Strong negative associations with the psychomotor development index were detected between stunting and being underweight, with a larger magnitude of effect for stunting (p<0.001). The strong relationship persisted even when the analysis was restricted to non-malnourished children. The psychomotor index increased by 2.07 points with every unit increase in height-for-age z-score. The relationship between low birth weight and psychomotor development appears to be mediated largely by postnatal growth and nutritional status. This association suggests that among undernourished children there is significant likelihood of a group that is developmentally delayed. It is important to emphasize developmental needs in programmes that target underprivileged children.

SCH is diagnosed after excluding all other causes of elevated TSH levels. Symptoms of SCH may vary from being asymptomatic to having mild nonspecific symptoms. The risk of progression to overt hypothyroidism is related to number of factors including initial serum TSH concentration, presence of auto antibodies, family history and presence goiter. Various screening recommendations for thyroid function assessment are in practice. There are still controversies surrounding SCH and associated risk of various cardiovascular diseases (CVDs), pregnancy outcomes, neuropsychiatric issues, metabolic syndrome, and dyslipidemia. Consensus will require more large randomized clinical studies involving various age groups and medical condition, especially in developing countries. All these efforts will definitely improve our understanding of disease and ultimately patient outcomes.

Current practice guidelines include the immediate administration of thrombolytic therapy in the absence of contraindications. However, thrombolysis for pulmonary embolism is said to be absolutely contraindicated in the presence of recent hemorrhagic stroke and other conditions. The current contraindications to thrombolytic therapy have been extrapolated from data on acute coronary syndrome and are not specific for venous thromboembolic disease. Some investigators have proposed that the current contraindications be viewed as relative, rather than absolute, in cases of high-risk pulmonary embolism. We present the case of a 60-year-old woman in whom massive pulmonary embolism led to cardiac arrest with pulseless electrical activity. Eight weeks earlier, she had sustained a hemorrhagic cerebrovascular accident-a classic absolute contraindication to thrombolytic therapy. Despite this practice guideline, we administered tissue plasminogen activator systemically in order to save the patient's life. This therapy did not evoke intracranial bleeding, and the patient was eventually discharged from the hospital. Until guidelines specific to venous thromboembolic disease are developed, we think that the current contraindications to thrombolysis should be considered on an individual basis in patients who are at high risk of death from massive pulmonary embolism.

Growth regulators, naphthalene acetic acid, gibberellic acid, and 2, 4-dichloro phenoxy acetic acid at the rates of (15, 25, and 35 ppm) were sprayed at full bloom stage on a popular mango cultivar ‘Dusehri’ growing in the subtropical region of Faisalabad in Pakistan. All of the treatments significantly influenced the number of fruits retained at pea, marble, and at harvest stages of fruit growth as compared to the control. Among the treatments, gibberellic acid sprayed at 35 ppm proved to be very effective with 31% more fruit retention than the control. In regard to fruit quality, gibberellic acid (35 ppm) and 2, 4-dichloro phenoxy acetic acid (15 ppm) resulted in a significant enhancement of fruit size in terms of fruit weight (140.8 and 130.1 g), which was 17.6 and 8.7% that of the control (119.8 g), respectively. The treatment 2, 4-D (35 ppm) recorded significantly higher TSS (19.5 °Brix) and TSS to titratable acid ratio over the control. Ascorbic acid content was significantly higher with 35 ppm NAA (61.9 mg/100 ml), while total sugars (20.4%) were significantly higher in 2, 4-D (35 ppm) than the control (11.4%). In general, application of growth regulators resulted in improved fruit retention and fruit quality.
