Open Lip Schizencephaly with Agenesis of Corpus Callosum: A Rare Embryological Defect In Combination.

A five week old newborne presented with recurrent abnormal movements . The child was borne of normal parents with non consangious marriage . There was no history of any ailment of mother during pregnancy and she was not on any drugs. The baby was borne by normal delivery and The CT Scan of the head showed Schizencephaly with Agenesis of Corpus Callosumwith gyralmalformation. Therewere no associated anomalies. Facial features were well developed and the muscle tone and power of the child was normal. The blood investigations were normal as was metabolic profile.

Morphology of Brachialis Muscle: Variations and Clinical Significance.

Background: Though rare but variations of brachialis muscle insertion have been reported. Material and Methods: The study was conducted on 115 upper limbs over a period of 4 years. The dissection of arm and forearm was done carefully to preserve all minute details ,observing the morphology of insertion pattern and nerve supply. Observation: Out of 115 specimens, 2 specimens showed insertion of brachialis into bicipital aponeuroses. Accessory slips were seen in 4 specimens which are mixed with main fibers at insertion point. Rarest of all was insertion of an accessory brachialis muscle on radial tuberosity in 2 specimens. The muscle originated from lateral border of shaft of humerus and shared a few fibers with main Brachialis muscle. The muscle was inserted into radius just below the radial tuberosity. Conclusion: The identification of an inter-nervous plane may allow for improvement in the current anterior and anterolateral surgical approaches to the humerus. This could be one of a possible etiology of Radial tunnel syndrome.

MORPHOLOGICAL AND MORPHOMETRIC STUDY OF JUGULAR FORAMEN IN SOUTH INDIAN POPULATION.

Background: The jugular foramen, the bony opening on the base of skull, is an opening through which pass the ninth, tenth, and eleventh cranial nerves, two dural sinuses, and the meningeal branches of the occipital and ascending pharyngeal arteries. The increasing use of modern diagnostic procedures and new surgical approaches has created a need for much more detailed anatomical studies and explanations. This article reveals some additional features. Material and Methods: 324 jugular foramina of skulls of persons of unknown age and gender were examined. The morphological characteristics of all the investigated jugular foramina were described, measured, and compared, taking into consideration their side. Results: Jugular foramina were studied for a review of its morphology, morphometry and its comparison with previous studies. Different shapes and sizes of jugular foramen were seen. Laterality was also noticed, compartmentation was also observed which was found to be statistically significant. Conclusions: A detailed examination of the jugular foramen anatomy was performed. The main types of jugular foramina and the frequencies of bipartite or tripartite division were established. Several dimensions of the parts of the jugular foramen were measured. Some new data could provide important information about the anatomy of the jugular foramen for reliable surgical interventions in this area.
