OBJECTIVES Sternal wound infections occurring after cardiac surgery have a critical impact on morbidity, mortality and hospital costs. This study evaluated the efficacy of a gentamicin-collagen sponge in decreasing deep sternal-wound infections in high-risk cardiac surgery patients. METHODS We conducted a quasi-experimental single-centre prospective cohort study in diabetic and/or overweight ...

The effects of both intracoronary and intravenous administration of nitroglycerin on transmural distribution of blood flow in the left ventricle after partial coronary artery occlusion was investigated using two independent methods. In 16 open chest, anesthetized dogs, tubing supplying the cannulated left coronary artery was partially occluded. Strain gauges sutured paralled to superficial and ...

BACKGROUND Chronic diseases involving the putamen and globus pallidus induce parkinsonism and other movement disorders. Sensory and motor dysfunction from deep middle cerebral artery infarction is usually due to an involvement of the internal capsule. The clinical picture associated with isolated infarction of the lenticular nucleus is less well established. OBJECTIVE To analyze clinical feat...

Deep sternal wound infection is a severe complication after open heart surgery. According to the different severity and dimensions of the deep sternal wound infection, the treatment method is different. In this study, we aimed to describe our experience with the rectus abdominis myocutaneous flap for large sternal wound management, especially when 1 or 2 internal mammary arteries were absent.Be...

STUDY OBJECTIVES Median sternotomy infections are a serious complication of cardiac surgery. The purpose of this study was to determine the patient characteristics and operative variables that predict incidence of sternal infection, and possibly its severity. DESIGN Univariate and multivariate retrospective analysis comparing patient, operative, and post-operative data in patients with and wi...

Recently, nitric oxide (NO) has been thought to be a neuronal messenger to evoke penile erection. NO synthase (NOS)-containing nerve fibers were identified and localized in human penile tissue, but detail distribution of NOS-containing nerve fibers in the human penis was unclear. In the present study we examined their distribution using histochemical staining of NADPH diaphorase (ND), which is ...

Facial artery is the principal artery of the face. It is a branch of external carotid artery, given off in the carotid triangle of the neck. It runs upwards and forwards in the submandibular region winding around the superficial part of the submandibular gland and the base of the mandible. It enters the face after piercing the investing layer of deep cervical facia. On the face, the artery has ...

Introduction Variations of the arterial patterns in the upper limb have been the subject of many anatomical studies due to their high incidence. Brachial artery is the main artery of the arm. It is a continuation of axillary artery at the lower border of teres major muscle. It usually terminates at the level of neck of radius in the cubital fossa by dividing into radial and ulnar arteries. The ...

After arising from the brachial artery in the cubital fossa the ulnar artery usually passes deep into the superficial flexor muscles of the forearm. In the lower two-thirds, it typically follows a sub-fascial course. In the present case, during a routine undergraduate course dissection of a cadaver, it was found that the ulnar artery arose normally as a terminal branch of the brachial artery in...
