Origin of the tendon of the long head of the biceps brachii muscle and its relationship with glenoid labrum in human foetuses / Origen del tendón de la cabeza larga del bíceps braquial y sus relaciones con el labro glenoideo en fetos humanos

We dissected the shoulders of 20 human foetuses to anatomical study. The purpose of this study was to characterize the anatomical origin of the long head tendon of the muscle biceps brachii (LHBBT) in human foetuses and its relationships with the glenoid labrum of the scapula. The results had shown that in approximately 95 percent of the cases the tendon of the long head of the biceps brachii inserts in the region of the glenoid labrum. This origin seems to form, together with the glenoid labrum, an anatomical complex. We conclude that the almost totality of the LHBBT was originated in the glenoidal labrum. For us, this furthermore reinforce the importance and necessity of better clarifying the anatomical and clinical implications of the biceps/labrum complex.

Fueron disecados los hombros de 20 fetos humanos con el propósito de hacer un estudio anatómico. El objetivo de este estudio fue cdeterminar el origen del tendón de la cabeza larga del músculo bíceps braquial en fetos humanos y sus relaciones con el labro glenoideo. Los resultados demostraron que, en cerca del 95 por ciento de los casos, el tendón de la cabeza larga del músculo bíceps braquial estaba originándose en la región del labro glenoideo. Este origen parece formar junto, con el labro glenoideo, un complejo anatómico. Concluimos que casi todos de los tendones del músculo bíceps braquial están insertados en el labro glenoideo. Esto es importante conocer para una mejor clarificación de las implicaciones clínico-anatómicas del complejo del bíceps/labro.

Metabolic syndrome in patients with prostate cancer.

CONTEXT AND OBJECTIVE: Prostate cancer (PCa) is the second most common cancer among men in Brazil. Recently, several studies have hypothesized a relationship between PCa and metabolic syndrome (MS). The aim here was to identify an association between MS and PCa. DESIGN AND SETTING: Cross-sectional study, Fundação de Beneficência Hospital de Cirurgia (FBHC) and Universidade Federal de Sergipe. METHODS: Laboratory and anthropometric parameters were compared between PCa patients (n = 16) and controls (n = 16). RESULTS: The PCa patients showed significantly greater frequency of MS than did the controls (p = 0.034). Serum glucose was higher and high-density lipoprotein-cholesterol was lower than in the controls, although without significant differences. There were significant differences in blood pressure (p = 0.029) and waist-to-hip ratio (p = 0.004). Pearson linear correlation showed a positive association between waist-to-hip ratio and prostate specific antigen (r = 0.584 and p = 0.028). Comparing subgroups with and without MS among the PCa patients, significant differences (p < 0.05) in weight, height, body mass index, hip circumference and lean body mass were observed, thus showing higher central obesity in those with MS. The serum glucose values were also higher in MS patients (p = 0.006), thus demonstrating that insulin resistance has a role in MS physiopathology. CONCLUSIONS: Our study suggests that MS may exert an influence on the development of PCa. However, it would be necessary to expand the investigation field with larger sample sizes and cohorts studied, to test the hypothesis generated in this study.
