Observamos las variaciones arteriales y musculares en y alrededor de la fosa cubital. La arteria braquial terminó 2 pulgadas por encima de la base de la fosa cubital. Las arterias radiales y cubitales entraron en la fosa cubital pasando delante de los tendones de los músculos braquial y bíceps braquial respectivamente. La arteria cubital estaba rodeada por el tercer fascículo del pronador teres, que tuvo su origen en la fascia cubriendo la parte distal del músculo braquial. Este músculo se unió a tendón de pronador teres distalmente y fue suministrado por una rama del nervio mediano. Este músculo podría alterar el flujo sanguíneo en la arteria cubital y puede causar dificultades para el registro de la presión sanguínea.

The left jugular foramen was narrowed by a thick bony projection. This bony projection filled the jugular fossa. This kind narrowing of the foramen might result in neurovascular symptoms as it transmits important cranial nerves and internal jugular vein.

It has two transverse processes, each one of which bears a foramen transversarium. The vertebral artery passes through this foramen. It has two lateral masses which articulate with the occipital condyles to form atlanto-occipital joints. Rarely, the atlas vertebra fuses with the occipital bone. We observed a potentially dangerous incomplete occipitalization of the atlas vertebra during osteology demonstration classes. The fusion resulted in reducing the diameter of foramen magnum approximately by 25%. The knowledge of this variation may be of importance to orthopedic surgeons, neurosurgeons, radiologists and anthropologists.

It is situated in the left hypochondriac region of the abdomen. It is about 1 inch thick, 3 inches broad, 5 inches long and weighs approximately 7 ounces. It is wedge shaped or tetrahedral in shape; and has two ends, two surfaces and three borders. Its posterior end rests on the upper pole of the left kidney and anterior end is supported by the phrenicocolic ligament. Its upper border shows characteristic notching. Its diaphragmatic surface is related to the diaphragm which separates it from the left lung, pleura and 9-11th ribs. Its visceral surface is related to the left kidney, stomach, left colic flexure and the tail of the pancreas. Normally, it is not related to the liver directly.

This report describes multiple variations in the upper abdominal vessels as found during the routine dissection in a 60-year-old male cadaver. The variations found were; presence of a celiaco-mesenterico-phrenic trunk, a common inferior phrenic trunk, 2 right renal arteries originating from abdominal aorta, 2 suprarenal arteries originating from the lower right renal artery, 3 right renal veins opening separately into inferior vena cava, and termination of right testicular vein into the lowest vein among the 3 right renal veins. The existence of a celiaco-mesenterico-phrenic trunk has not been reported yet. Although, other variations reported in this case exist as individual variations, a concomitant variation of them has not been reported yet. The knowledge of such variations is quite useful in planning any upper abdominal surgery.

Total of 120 skin samples taken from five different areas of head and neck region in two directions from 12 cadavers were processed and stained with special stain Verhoeff-van Gieson stain. Quantitative fractions of collagen and elastic fibres were measured by image analysis using tissue quant software Version 1.0. There was a significant differences of quantitative fractions of collagen and elastic tissue between horizontal and vertical direction in areas where skin was thick and tight (scalp and forehead with p<0.01). Relatively thinner and loose areas of skin (submandibular area, neck) showed statistically significant asymmetrical distribution of elastic tissue only (p <0.01). In very thin and loose skin (lateral canthal area), the difference in distribution of both collagen and elastic tissue was not statistically significant. Asymmetrical distribution of dermal collagen and elastic tissue in two directions of the sections in the same region could be one of the causes of difference in the appearance of scar placed in different directions of the same region.

All previously reported cases of this rare anomaly were identified during procedures such as orchiepexy, inguinal hernia repair, vasectomy, varicocoelectomy, and radical prostatectomy. Here, we report a case of unilateral duplicated vas deferens noted in an adult cadaver during regular dissection for medical students. The right spermatic cord contained 2 separate and completely developed cord-like structures. Both cords communicated separately with the tail of the epididymis. When traced cranially, both traversed the inguinal canal as content of the spermatic cord and finally fused at the level of the deep inguinal ring. No other variations were found in the testis or epididymis, and no variations were seen in the left spermatic cord. In addition, no associated renal abnormalities were noted.

JCV has been detected in 5% of arterial samples from young trauma victims [15]. It would not be surprising if arterial infection upregulated endothelial adhesion molecules, and local levels of fibrinogen, making intravascular clot formation more likely. Antibodies to JCV are more common in those with brain tumours [16], and the oncogenic potential of JCV has been established in vitro [17]. Polymerase chain reaction (PCR) detection of JCV DNA in cerebrospinal fluid, from patients during prolonged illnesses, might help to prove that JCV reactivation occurs on a regular basis. Careful consideration would have to be given to the timing, sensitivity, and appropriate use of such an invasive test. Establishing whether chronic latent infection, even without significant reactivations, could cause disease over many decades, presents a significant challenge. Other polyoma viruses such as BK virus (BKV), and simian virus 40 (SV40) [16] should also be tested to determine whether these alter the risk of disease due to JCV. Can we afford to dismiss the potential benefits of attacking this newly discovered, but perhaps ancient timebomb, that persists in so many of our brains, and remains so poorly understood? References

Modification of current examination techniques may be necessary to detect anomalies and lead to more accurate diagnosis. We examined 500 subjects using an expansion of current techniques to elicit the range of variations in FDS function discernable on clinical examination. Methods FDS function was evaluated by asking subjects to flex the finger of interest while all other fingers were held fully extended at the metacarpophalangeal and interphalangeal joints. Isolated flexion at the proximal interphalangeal (PIP) joint indicated independent FDS function. Obligatory flexion at the distal interphalangeal (DIP) joint indicated flexor digitorum profundus (FDP) activity. Because FDS activity could not be evaluated if concurrent FDP activity was present, these fingers were designated as having FDP substitution. Difficulty isolating PIP joint flexion suggested connections to adjacent FDS or FDP, prompting the examiner to serially release adjacent fingers while observing for improvement in PIP or DIP range of motion. Results Independent FDS function was most consistently present in the ring and middle fingers, less so in the index finger, and least in the small finger. Variations included FDP substitution or connections to flexor tendons in 1 or 2 adjacent fingers with or without evidence of FDP substitution. Absent FDS function cannot be presumed in any subject based solely on clinical examination of a single digit. Conclusions Current examination techniques are inadequate to discern among the multiple variations of FDS function. An expanded examination technique is recommended for accurate diagnosis of FDS function following flexor tendon injury.

Additionally, on the right side of the same cadaver, the common peroneal nerve passed just inferior to the piriformis muscle and the tibial nerve emerged inferior to the gemellus superior, between the gemellus superior and obturator internus muscles. Then, both of the nerves coursed posterior to the obturator internus, gemellus inferior and quadratus femoris muscles. The gemellus superior muscle, lying just posterior to the tibial nerve may cause to the symptoms of sciatica, because of the compression of the tibial nerve between the gemellus superior and obturator internus muscles. This pathology may lead to a new syndrome; the gemellus superior syndrome, just like the piriformis syndrome. As a conclusion, in the etiology and pathogenesis of sciatica, in addition to the priformis muscle, the abnormalities of the other gluteal external rotator muscles of the hip joint must also be taken into consideration by the clinicians. MR imaging of this region will be very helpful for the accurate diagnosis of this type of pathologies.
