A study of sexual dimorphism of femoral head in Gujarat region.

Various diameters of head of femur have been in use for sex determination. These diameters vary region wise also. Therefore we undertook the study in Jamnagar region of Gujarat. Maximum diameter of the femoral head was measured in 184 dry, normal, adult, human femora (136 male & 48 female) obtained from M. P. Shah Medical College Jamnagar Gujarat. Mean Values obtained were, 43.75 and 40.33 for right male and female, and 43.88 and 40.64 for left male and female respectively. Higher value in male was statistically highly significant (P< 0.001) on both sides. The data was subjected to demarking point (D.P.) analysis. Maximum head diameter identified 11.90% of right male femora and 7.25% of left male femora; in female it identified 4% of left female femora while it was not useful (0.00%) for right female bone. Though the sex of the bone can be determined from head of the femur bone, in itself it is far from conclusive.

Sexual dimorphism of bicondylar width of Femora.

Background: Sexual identification from the skeletal parts is very important medicllegaly as well as anthropologicaly. Present study aims to ascertain values of femoral bicondylar width and to evaluate its possible efficacy in determining correct sexual identification.Methods: Study sample consisted of 184 dry, normal, adult, human femora (136 male & 48 female) from skeletal collections of Anatomy department, M. P. Shah Medical College, Jamnagar, Gujarat. Bicondylar width was considered as maximum distance between medial and lateral femoral condyle, measured with the Vernier caliper. Results: Mean Values obtained were, 76.84 and 72.34 for right male and female, and 76.64 and 72.84 for left male and female respectively. Higher value in male was statistically highly significant (P< 0.001) on both sides. Demarking point (D.P.) analysis of the data showed that right femora with bicondylar width more than 80.20 were definitely male and less than 65.50 were definitely female; while for left bones, femora with bicondylar width more than 80.76 were definitely male and less than 66.53 were definitely female. Conclusions: Bicondylar width identified 22.40% of right male femora and 14.49% of left male femora; it was not useful for female bone.

Duplication cyst of the pylorus--a rare cause of gastric outlet obstruction in the newborn.

Duplication cysts of the pylorus are the rarest of alimentary tract duplications with very few reported cases. We present such a cyst in a neonate presenting with gastric outlet obstruction. We have also reviewed the literature and outlined the theories of origin, modes of presentation, diagnosis and the surgical procedures. Even though several modes of surgery have been described, it is best to individualize the surgical option in each case. The results depend on the nature and site of duplication, complications and the associated anomalies.

Extrarenal Wilms' tumour--a case report and review of literature.

Extra renal Wilm's tumour (EWT) is an exceedingly rare entity and needs to fulfill certain criteria. Of the 48 cases reported, only about 36 have been found to be convincingly proved. We present one more well proven case of EWT and have extensively reviewed the literature. The diagnostic, staging and management guidelines are discussed. Amongst the reported cases, the behaviour of the tumour appears to parallel that of similarly staged "intra renal" Wilm's tumour. Hence the staging and the management protocols of "intra renal" Wilm's tumour can well be applied to tumour of extra renal location albeit with some modifications.

Benign neonatal pneumoperitoneum--an enigma.

A case of neonatal pneumoperitoneum in absence of a bowel perforation or intrathoracic pathology has been reported. The cause of such a rare manifestation remains to be established.

Developmental anomalies associated with hypospadias.

Hundred and thirty patients with hypospadias were studied between 1983 and 1990, with an aim of analysing the associated anomalies in these patients. Urogenital anomalies were observed in 30% and extra-urogenital anomalies were noted in 16%. Undescended testis was the most frequently seen anomaly, having been noted in 6.9% of 130 cases. Vesico-ureteral reflux was present in 5.4% and inguinal hernia in 3.8%. The incidence of these anomalies increased in proportion to the severity of penile deformity. The present article emphasizes the need for systemic urological and endocrinal examination, especially in severe cases of hypospadias.
