Multiple variations of the azygos venous system

In a dissection performed in our department, we observed multiple variations of the azygos venous system. The hemiazygos vein was absent. The posterior 8th, 9th, and 10th intercostal veins united and their common trunk crossed the vertebral column obliquely lying anterior to the aorta and posterior to the esophagus and opening into the azygos vein at the level of T7-T8 vertebrae. The 7th left posterior intercostal vein also crossed the column anteriorly and joined the common trunk. The present report identifies the variable positions and courses of the veins related to the azygos system. It is important to keep in mind that different courses of the azygos system do exist, so that extra caution is required during surgery of the mediastinum and also in appropriately interpreting the radiographs.

Comparison of nerve conduction velocities of lower extremities between runners and controls

Peripheral nerve injuries can occur in runners, but large numbers of nerve injuries remain subclinical. Identification of nerve injuries needs an understanding of common sites of entrapment in running. Fourteen asymptomatic male middle-distance runners and 14 non-active subjects participated in this study. The neurophysiologic study consisted of motor and sensory nerve conduction of medial and lateral plantar nerves, sensory nerve conduction of sural and superficial peroneal nerves, and motor nerve conduction of common peroneal nerve. Active range of motion and muscle strength assessment (dorsi flexion/plantar flexion; inversion/eversion) as measured using a Biodex System3 Dynamometer were observed to be within normal limits for both groups. The medial plantar (sensory) nerve and sural nerve distal latencies were significantly prolonged and sensory conduction velocities were significantly delayed in the runners compared with the control subjects. Many of the asymptomatic runners with abnormal nerve conduction tests in this study may represent presymptomatic or asymptomatic neuropathy similar to the type of subclinical entrapment neuropathy.

Unusual origin of the right renal artery: a case report

An anomalous origin of the right renal artery was observed in a 50-year-old male cadaver. The importance of this variation of the right renal artery and superior mesenteric artery arising from a common trunk is emphasised.

Profesyonel futbolcularda egzersiz öncesi ve sonrası iskemi modifiye albumin düzeyleri

Objectives: The ischemia-modified albumin (IMA) test is a promising indicator of myocardial ischemia in the early diagnosis of the acute coronary syndrome (ACS). Recent studies examining alterations in IMA levels caused by myocardial ischemia that develops during exercise have shown contradictory results. There has been an increase in severe exercise-related cardiac events in football. We therefore, assessed IMA levels before and after exercise in professional soccer players in order to examine the effect of the exercise on IMA levels. Methods: Blood was collected from professional soccer players before and after exercise. IMA levels were measured by using spectrophotometric methods, and the albumin levels were measured in an autoanalyzer. Results: The average pre- and post exercise IMA levels of 16 soccer players were found to be 0.438±0.071 and 0.386±0.069, respectively. The pre- and post exercise albumin levels of the same group were 4.08±0.20 g/dL and 4.21±0.19 g/dL, respectively. There was a strong negative correlation between post exercise IMA and albumin levels, which was statistically significant (r = -0.535. p = 0.033).Conclusion: IMA levels should be examined not only in noncardiac pathologies, but also in specific serum albumin concentrations and in individuals practicing vigorous sport activities

Biochemical parameters in professional male footballers before and after training

ABSTRACT The goal of this study is exploring serum alterations related to acute coronary sendrom, muscle deterioration, hypoglysemia and the other variables in the serum of the fifteen footballers. Fifteen professional male footballers (mean (SD) age: 24 (4.4) years) were gathered from a 3rd league team. Blood samples were collected from them before and after exercise. Blood samples were analyzed by standard methods and the results were corrected in the biochemistry laboratory. The average pre- and post-exercise biochemical values of 15 footballers are found below. The glucose in the serum is 62.3 ± 3.9(before) and 69.5 ± 7.8(after) (P<0.05) for pre- and post-exercise, respectively. The urea in the serum is 36 ± 9.5(before) and 34.4 ± 9.2(after) (p>0.05). The creatine in the serum is 0.9 ± 0.l(before) and 0.8 ± 0.9(after) (p>0.05). The CK in the serum is 309.9 ± 200.9(before) and 253 ± 149.7(after) (p>0.05). The CK-MB in the serum is 17.9 ± 6.3(before) and 14.5 ± 5.4(after)(p>0.05). The total bilirubin in the serum is 0.8 ± 0.4(before) and 0.8 ± 0.5(after) (p>0.05). The albumin in the serum is 4.1 ± 0.3(before) and 4.1 ± 0.2(after) (p>0.05). The BUN (blood urea nitrogen) in the serum is 16.7 ± 4.4(before) and 16.3 ± 4.5(after) (p>0.05). Although broad variety of biochemical perturbations is present during acute physical stress, many parameters remain within regular limits.
