Climate and head form in India.
The relationship between head form and climatic variation was investigated in different tribal and caste populations of India. The magnitude of the cephalic index varies significantly in different zones. In tropical zones, head form is longer (dolicocephalic), but in temperate zones, head form is more round (mesocephalic or brachycephalic), especially among Scheduled Tribes (ST) and Scheduled Castes (SC) than among other castes. These trends possibly support a climatic adaptation model in head form differences among ST and SC in India.

Spectrum of pulmonary sequestration: association with anomalous pulmonary venous drainage in infants.
Pulmonary sequestration is a spectrum of related lesions, each of which may be absent or present: (1) bronchial sequestration of pulmonary parenchyma; (2) arterial supply from systemic circulation; (3) anomalous pulmonary venous drainage to the right atrium; (4) communications between bronchus and esophagus; (5) defects of diaphragm; (6) gross lung anomalies, such as horseshoe lungs or hypoplasia. Any combination of these primary lesions can occur in an individual patient. Diagnosis should be directed towards each component of the spectrum. Of special importance is the venous connection, as anomalous pulmonary venous drainage can involve not only the sequestered segment but the entire ipsilateral lung, making surgical therapy far more complex. Treatment of choice is surgical resection, associated, if needed, with rerouting of the pulmonary venous return. Classification of sequestration of the lung as intra- and extralobar is of secondary importance: these 2 groups do not represent lesions of different embryological significance.

Anomalous mitral arcade: echocardiographic and angiographic recognition.
A patient with sudden onset of hemiplegia was noted to have an anomalous mitral arcade at cardiac surgery. Echocardiographic and angiographic data are correlated with the anatomic findings. The clinical significance of this anomaly is discussed.

Angiographic evidence of absent ductus arteriosus in severe right ventricular outflow obstruction.
The angiocardiograms of 5 newborn infants with autopsy and/or surgically-proven congenital absence of the ductus arteriosus (ADA) and right ventricular outflow obstruction (Group A), and of 14 neonates with pulmonary atresia complex and patent ductus arteriosus (Group B) were reviewed. Aortic size was similar in both groups; however, the diameters of the right and left pulmonary arteries were much smaller in Group A than in Group B (right pulmonary artery: 2.6 vs 4.5 mm, P less than 0.005; left pulmonary artery: 2.5 vs 4.3 mm, P less than 0.005). Extensive bronchial collaterals were observed in Group A but not in Group B. Tricuspid aortic valve stenosis was present in 2 patients in Group A but in none in Group B. The diagnosis of ADA may be made in newborn infants with severe right ventricular outflow obstruction if the angiocardiograms reveal hypoplasia of the pulmonary arteries, extensive bronchial collaterals, and nonvisualization of the ductus arteriosus. Other suggestive features include aortic valve stenosis and/or right aortic arch with aberrant left subclavian artery.
Angiocardiography↗
Direct entry of the right superior vena cava into the left atrium with aneurysmal dilatation and stenosis at its entry into the right atrium with stenosis of the pulmonary veins: a rare case.
This is the first autopsied case reported in the English language literature wherein the right superior vena cava entered both atria with obstruction of the entry into the right atrium, aneurysmal dilatation of the proximal part of the superior vena cava, and entry of the stenosed right upper pulmonary vein into the aneurysmal sac. The aneurysmally dilated right superior vena cava communicated directly with the left atrium. In addition, the remainder of the pulmonary veins, all of which were markedly stenosed, entered the left atrium. The embryogenesis of this unique malformation is briefly discussed.

Hypoplastic left heart syndrome with dysplastic pulmonary valve with stenosis.
A dysplastic pulmonic valve in hypoplasia of aortic tract complex has not been dealt with in the literature. The recent attempted surgical correction for hypoplasia of aortic tract complex has given some hope of survival in this entity. The integrity of the tricuspid and pulmonic valves is important while considering total surgical correction. We describe three hearts of hypoplasia of aortic tract complex with dysplastic pulmonic valve. The echocardiographic recognition and the significance of the dysplastic nature of the pulmonary valve in the light of surgery are emphasized.

A cross between truncus arteriosus communis and aortopulmonary septal defect: a hitherto undescribed entity.
Case history and necropsy findings of a 5-month-old infant with a unique heart defect with features of truncus arteriosus communis and aortopulmonary defect in combination with severe tricuspid stenosis are presented. There is a wide spectrum of remarkable heart defects between truncus arteriosus communis and aortopulmonary septal defect.

Spatial patterns of anthropometric variation in India with reference to geographic, climatic, ethnic and linguistic backgrounds.
BACKGROUND: Anthropometric variation can be fruitfully utilized to investigate microevolutionary processes. Anthropometric variations in the Indian subcontinent based on stature and three indices (Cephalic Index, Nasal Index, and Total Facial Index) are highly variable and discriminative among populations across geographical regions. AIMS: Anthropometric variation in stature, Cephalic Index (CI), Nasal Index (NI) and Total Facial Index (TFI) were investigated with respect to ethnic, linguistic, geographical and climatic affiliation, across the Indian subcontinent. SUBJECTS AND METHODS: Published data on anthropometric variations of 531 populations from the Indian subcontinent were analysed using discriminant analysis and spatial autocorrelation analysis. RESULTS: Discriminant analysis of the four anthropometric variables shows that stature and NI are good discriminators for populations of different languages. Stature, NI and CI discriminate well among populations of diverse ethnic origin and climatic conditions in different regions. TFI is not a good discriminator for populations of diverse ethnic, linguistic and climatic attributes. Spatial autocorrelation analysis showed significant departure from randomness, suggesting geographic structuring. The Moran's I estimate is positive and statistically significant for the four variables at low distances but exhibits significant negative association at higher values. CONCLUSION: The results suggest geographical clines for the four anthropometric variables and indicate the influence of population structure on the studied variables.

Congenital polyvalvular cardiac disease without chromosomal abnormalities.
Congenital polyvalvular cardiac disease has been reported in association with trisomies 18, 13, and 15. Ninety-three percent of trisomy 18 patients have polyvalvular disease, and 34% have all four valves involved. Four cases of polyvalvular disease without chromosomal abnormalities were studied and compared to polyvalvular disease with trisomy. In these four cases, all four valves were markedly abnormal with nodularity and reductant tissue; one aortic and two pulmonary valves were bicuspid; and one aortic, two tricuspid, and three mitral valves were unicuspid. The chordae tendineae were generally abbreviated and papillary muscles were hypoplastic. Microscopically, the valves had spongiosis, vacuolar degeneration, and a decrease in elastic fibers. Multiple other cardiac anomalies were present in each case. Three of the four cases also had significant extracardiac anomalies, which were lethal in two cases. The fourth case with no other anomalies had a history of maternal tobacco, alcohol, and cocaine abuse, with the latter being detected in fetal urine after birth. There does not appear to be a significant difference between polyvalvular disease with and without trisomy. Polyvalvular disease is usually not an isolated disorder but is associated with other intra- and extracardiac anomalies.
