Calcium supplementation for preterm and low birth-weight neonates.
Early neonatal hypocalcemia is a common problem in prematurely born infants. To prevent it, therapy with intravenous calcium is often advised. We compared the efficacy and side-effects of intravenous and oral calcium supplementation in preterm and low birth-weight babies. Both the groups were comparable for birth weight, gestational age and cord blood calcium level. Oral calcium administration was as efficacious as intravenous administration in babies of all gestational age groups and birth-weight groups. Side effects associated with therapy were less common and of lesser severity in oral supplementation group. Lower cost and ease of administration were additional benefits.

Relative accuracy of diagnostic method in bronchogenic carcinoma.
The definitive diagnosis confirming lung cancer by microscopic examination is indicated before the therapy whenever possible and particularly prior to undertaking thoracotomy in situations when tissue diagnosis is not achieved. In such situations the thoracotomy becomes diagnostic with the therapeutic procedure. In clinically suspected cancer of the lung, histological confirmation is usually available at times, and cytology confirmation must suffice. At Tata Memorial Hospital for cancer and allied diseases in Bombay, India, we analyzed retrospectively 298 cases, which were submitted for different diagnostic procedures in suspected lung cancer. The yield of positive tissue diagnosis of malignancy obtained by each method is described and discussed. We observed that transthoracic needle biopsy gives significant information on inflammatory diseases of the lung. The sputum examination makes the simplest revelation of malignant cells, to an extent of 53% at our institution for three successive samples.

Exploratory thoracotomy on a patient with previous malignancy--"metastasis" or "new primary" or "unrelated lesion".
Surgical resection of a solitary pulmonary metastasis is an established procedure. A medical generation ago when such a shadow appeared on chest roentgenogram of a patient who had known cancer elsewhere in body, it was assumed to be "metastasis" from an extrathoracic site. With increasing advances in knowledge, the occurrence of second primary or new lesion is now no more curiosity in clinical practice. To one's surprise, the lesions that are assumed to be metastatic have often turned out to be "fresh" lesion or even unrelated benign, granulomatous, inflammatory, or parasitic lesion. This paper analyses 66 patients during a period of 20 years who underwent thoracotomy for such solitary pulmonary lesions, and emphasizes the role of diagnostic-cum-therapeutic-thoracotomy in such a clinical situation where in prethoracotomy tissue diagnosis is not forthcoming.
