Preinguinal Splitting and Reunion of Femoral Nerve Entrapping the Fleshy Fibres of Iliacus Muscle - A Case Report.

Division of nerves close to their origin and muscular entrapments by nerves in the limbs is not very common. Femoral nerve is the largest branch of the lumbar plexus and arises from dorsal divisions of ventral rami of L2 to L4 spinal nerves. During routine cadaveric dissection for first year medical students at Melaka Manipal Medical College (Manipal Campus), Karnataka, India, we observed a variation in the division and course of left femoral nerve in about 65-year-old male cadaver.

Unique formation of sciatic nerve below the piriformis muscle - a case report.

Dorsal and ventral divisions of ventral rami of lower lumbar and sacral spinal nerve were found to pass ventral and dorsal to the piriformis muscle respectively. These divisions joined each other below the piriformis muscle to form sciatic nerve. This low formation of sciatic nerve was observed in distal part of left gluteal region of a 50-year-old male cadaver.

The foramen ovale morphometry of sphenoid bone in South Indian population.

Background: The foramen ovale is an oval opening in the greater wing of sphenoid bone transmitting the mandibular nerve as its major content. It serves as an important landmark for neurosurgeons in certain procedures as to gain access to trigeminal nerve. Therefore, its topographic position in relation to adjacent bony landmarks provides useful tool during these procedures.

Variant course of posterior circumflex humeral artery associated with the abnormal origin of radial collateral artery: could it mimic the quadrangular space syndrome?

Variations in the origin of axillary artery branches are common. But, distinctly abnormal course of its posterior circumflex humeral branch is rare. We are reporting a case of posterior circumflex humeral artery (PCHA) originating from the axillary artery, passing through lower triangular space to reach the scapular region where it accompanied the axillary nerve and posterior circumflex humeral vein to pass around surgical neck of humerus, deep to the fibers of deltoid.

Anomalous muscle from the fascia around popliteal vessels.

Normally, the popliteal fossa contains popliteal vessels, tibial and common peroneal nerves. An occurrence of muscle in the popliteal fossa is very rare. During routine dissection classes for medical undergraduates, an anomalous muscle in the popliteal fossa was encountered.

Separate Belly and Tendon of Flexor Digitorum Superficialis to the Fifth Digit.

Variation in the origin of long flexor tendons in the anterior compartment of forearm is common. During routine cadaveric dissection at Melaka Manipal Medical College (Manipal Campus), we observed a separate muscle belly and tendon of flexor digitorum superficialis (FDS) to the fifth digit in the right upper limb of a 60 year-old male cadaver. The anomalous muscle belly originated from the common flexor tendon from the medial epicondyle of the humerus and continued as a thin tendon at the middle of the forearm to get inserted into the middle phalanx of the fifth digit.

Effect of topical phenytoin on burn wound healing in rats.

To evaluate the effect of phenytoin on burn wounds and to compare the effect of the combination of topical phenytoin preparation in dexamethasone treated burn wounds in rats, partial thickness thermal burn wounds were inflicted upon five groups of six rats each. Group I was assigned as control, Group II received the standard silver sulphadiazine, Group III was given topical phenytoin and Group IV received injection dexamethasone, Group V received the combination of the phenytoin and the dexamethasone. The parameters observed were epithelialization period, percentage of wound contraction and histopathological analysis as indicative of the process of healing.

Anomalous branching pattern of the aortic arch and its clinical applications.

The aortic arch gives rise to three classical branches, namely the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. We report a rare variation of the left common carotid artery and the right vertebral arteries originating from the brachiocephalic trunk, and the left vertebral artery that was arising from the arch of the aorta, proximal to the origin of the left subclavian artery. Variations in the branching pattern of the arch of aorta can alter the cerebral haemodynamics that leads to cerebral abnormalities.

UV-killed Staphylococcus aureus enhances adhesion and differentiation of osteoblasts on bone-associated biomaterials.

Titanium alloys (Ti) are the preferred material for orthopedic applications. However, very often, these metallic implants loosen over a long period and mandate revision surgery. For implant success, osteoblasts must adhere to the implant surface and deposit a mineralized extracellular matrix (ECM).

Staphylococcus aureus induces expression of receptor activator of NF-kappaB ligand and prostaglandin E2 in infected murine osteoblasts.

Osteomyelitis is an inflammatory disease of the bone that is characterized by the presence of necrotic bone tissue and increased osteoclast activity. Staphylococcus aureus is responsible for approximately 80% of all cases of human osteomyelitis. While the disease is especially difficult to treat, the pathogenesis of S.

Nafcillin-loaded PLGA nanoparticles for treatment of osteomyelitis.

The goal of this investigation is to develop poly(DL-lactide-co-glycolide) (PLGA) nanoparticles for the delivery of antibiotics such as nafcillin to osteoblasts. This is important in order to treat Staphylococcus aureus-mediated osteomyelitis. The latter is often chronic and highly resistant to antibiotics.

Effect of Centella asiatica L (Umbelliferae) on normal and dexamethasone-suppressed wound healing in Wistar Albino rats.

Centella asiatica is a reputed medicinal plant used in the treatment of various skin diseases in the Indian system of medicine. The objective of the study presented in this article was to evaluate the wound-healing potential of the ethanolic extract of the plant in both normal and dexamethasone-suppressed wound healing. The study was done on Wistar albino rats using incision, excision, and dead space wounds models.

Effect of intracerebroventricular methotrexate on brain amines.

Intrathecal methotrexate in children with leukemia is known to cause seizures, dementia, leukoencephalopathy and cognitive dysfunction. To investigate the role of brain amines in cognitive dysfunction, male Wistar rats were given multiple intracerebroventricular injections of methotrexate. Our earlier studies in this regard revealed disruption of brain monoamines in hippocampus with severe cytotoxic effect on CA4 hippocampal neurons.

Effect of Ocimum sanctum Linn. on normal and dexamethasone suppressed wound healing.

Ethanolic extract of leaves of O. sanctum was investigated for normal wound healing and dexamethasone depressed healing using incision, excision and dead space wound models in albino rats. The extract of O.

Anatomy that must be taught to a medical undergraduate: an interview-based survey in an Indian medical school.

Confusion still exists about the anatomy to be taught to the medical undergraduate. We did an interview-based survey at the Melaka Manipal Medical College in Manipal, India, to try to evaluate the quantum of anatomy that should be taught to the medical undergraduate. The results suggest that excluding trivia and making anatomy more clinically oriented would be advantageous.

Pyramid environment reduces the wound healing suppressant properties of dexamethasone in albino rats.

With a view to investigate the contribution and role of environment within a wooden pyramid model on the wound healing suppressant effect of dexamethasone in rats, wound breaking strength, dry weight, hydroxyproline content and histology of granulation tissue of the dead space wound were studied in rats. The results indicate that the environment within the wooden pyramid not only promotes significant wound healing but also reduces the wound healing suppressant effect of dexamethasone. Histological studies also confirmed the results.

Evaluation of hepatoprotective activity of Ginkgo biloba in rats.

The mechanism of hepatoprotective effects of Ginkgo biloba (GB), an herbal preparation with wide variety of therapeutic application, on paracetamol (Pcml) induced hepatic damage in rats has been investigated. GB treatment restored the marker enzyme levels indicating the in vivo protective effects against Pcml induced liver damage both in preventive and curative aspects. GB also reversed the increased TBARS levels, and elevated the GSH content of the liver.

Hippocampal brain amines in methotrexate-induced learning and memory deficit.

Intrathecal methotrexate in children with leukemia is known to cause seizures, dementia, leukoencephalopathy, and cognitive dysfunction after long-term treatment. To investigate the cognitive dysfunction, male Wistar rats were given multiple intracerebroventricular injections of methotrexate. Its effect on behaviour was tested in the two-compartment conditioned avoidance task and dark-bright arena test.

An anomalous muscle in the region of the popliteal fossa: case report.

Variations in the hamstring muscles are not common. We describe here a rare anomalous muscle in the popliteal fossa and speculate on its functional significance.

An experimental model to produce partial thickness burn wound.

Simple burn wound models are always warranted. In view of this a partial thickness reproducible 2 degrees C burn wound has been produced using hot molten wax. This model is simple, convenient, and could be used to monitor wound contraction and epithelization in burn wounds.

Effect of tolmetin and its copper complex on wound healing.

Dose matched comparison between copper complex of tolmetin(Tol-Cu) and tolmetin(Tol) was carried out in male albino rats bearing either sutured incision, dead space or excision wounds. Results showed that Tol significantly decreased tesile strength of incision and dead space wound. This effect was totally reversed by copper present in Tol-Cu.
