Lactate and Pyruvate Levels in the Testicular Vein of Subfertile Males with Varicocele as a Test for the Theory of Underlying Hypoxia

Lactat- und Pyruvat-Werte in der Vena testicularis von subfertilen Männern als Test für die Theorie der vorhandenen Hypoxie
Um die These von der testikulären Hypoxie bei subfertilen Männern mit Varikocele zu überprüfen wurden die Blutwerte von Lactat und Pyruvat aus der Vena testicularis mit denen einer Kontrollgruppe verglichen. Statistisch ergab sich ein niedrigerer Mittelwert für Lactat und Pyruvat bei den Varikocele-Patienten. Daraus wird die Schlußfolgerung gezogen, daß bei Varikocele keine Akkumulation von Milchsäure erfolgt und daß damit eine Hypoxie ausgeschlossen werden kann. Als die Mittelwerte der Konzentrationen für Lactat und Pyruvat in der Vena testicularis miteinander korreliert wurden, deutete sich an, daß bei Vorhandensein einer Varikocele eine gestörte Glykolyse besteht, die dem Stadium der Pyruvatbildung vorhergeht.     

Octylcyanoacrylate (Dermabond) for skin closure at the time of head and neck surgery: a longitudinal prospective study

OBJECTIVES: A prospective non-randomised evaluation of the octyl-2-cyanoacrylate (Dermabond) for skin closure in head and neck surgery. MATERIALS AND METHODS: An inception cohort of 52 patients managed by six otorhinolaryngologists head and neck surgeons at a single institution (university teaching and tertiary referral center) during the months of May-July 2004. The length of the skin incision varied from 3 to 30 cm (mean: 7 cm). Morbidity evaluation, longitudinal analysis of the evolution of the scar, and analysis of the degree of satisfaction. RESULTS: Postoperative death was not encountered. The overall morbidity rate was 3.8% (2/52). There was no instances of wound dehiscence's. A subcutaneous abscess was noted in one patient. From an aesthetic point of view, the scar appearance was considered to be slightly retracted during the first postoperative month and to be very good 2 to 4 months from initial surgery. Only one patient developed a minimal cheloid scar. Among the 47 patients who expressed an opinion postoperatively regarding the use of the octyl-2-cyanoacrylate (Dermabond) for skin closure, the degree of satisfaction was very high due to the ability to take an early shower (40 patients) followed by the lack of skin sutures (5 patients) and the lack of any allergic skin reaction (2 patients). CONCLUSION: At our department, the octyl-2-cyanoacrylate (Dermabond) for skin closure at the time of head and neck surgery is becoming more and more utilized due to the completion of a solid and aesthetic suture, the ability to take an early shower and the high degree of satisfaction expressed by the patients.     

Primary health care: a framework for policy development

Primary health care has utility for policy development at all levels of organization in any nation, including policies influencing the health of persons living with severe and persistent mental illnesses. Using the primary health care framework, policies to improve health and housing for this population evolve from intersectoral collaboration. Active participation by those persons whose essential health is compromised by housing that is not acceptable, adequate, suitable, and affordable is required. Appropriate and affordable methods that address health challenges are identified. Access to services meeting essential health care needs of citizens has potential for healthy outcomes.
