Hypothenar island flap: A safe and excellent choice for little finger defects

Soft-tissue defects of the little finger are challenging especially when bone, tendon or vascular pedicle is exposed because of trauma. The hypothenar island flap is easy to harvest and has a good colour and texture match to the little finger pulp. We present nine clinical cases of soft tissue defects of the little finger covered using the reversed hypothenar fasciocutaneous island flap. This article intends to highlight the ease of elevation and good clinical results of the hypothenar flap which is rarely used.KEY WORDS: Hypothenar island flap, island flap, soft-tissue defects of the little finger     

P wave dispersion is prolonged in patients with Wilson＇s disease

AIM： To investigate the P wave dispersion as a noninvasive marker of intra-atrial conduction disturbances in patients with Wilson＇s disease.
METHODS： We compared Wilson＇s disease patients （n = 18） with age matched healthy subjects （n = 15） as controls. The diagnosis was based on clinical symptoms, laboratory tests （ceruloplasmin, urinary and hepatic copper concentrations）. P wave dispersion, a measurement of the heterogeneity of atrial depolarization, was measured as the difference between the duration of the longest and the shortest P-waves in 12 lead electrocardiography.
RESULTS： All the patients were asymptomatic on cardiological examination and have sinusal rhythm in electrocardiography. Left ventricular and left atrial diameters, left ventricular ejection fraction and left ventricular mass index were similar in both groups. The Wilson＇s disease patients had a significantly higher P wave dispersion compared with the controls （44.7 ± 5.8 vs 25.7 ± 2.5, P 〈 0.01）.
CONCLUSION： There was an increase in P wave dispersion in cardiologically asymptomatic Wilson＇s disease patients which probably represents an early stage of cardiac involvement.     

Evaluating the effect of polytetrafluoroethylene and extractum cepae-heparin-allantoin gel in peripheral nerve injuries in a rat model

BACKGROUND:Peripheral nerves can be injured by congenital, mechanical, thermal or chemical causes. Peripheral nerve injuries are increasing in frequency, particularly in countries that are becoming more industrialized. Nerve and extremity injuries result in work loss and high treatment costs, and can lead to separation of patients from their social environment. Failure of nerve repair causes muscle functional losses, sensory losses and painful neuropathies.OBJECTIVES:To compare the effects of condensed polytetrafluoroethylene (cPTFE) and cPTFE-extractum cepae-heparin-allantoin (cPTFE-EHA) gel compound on nerve and functional recovery, and the prevention of adhesion and scar tissue formation after total peripheral nerve injury repaired by primary suture in a rat model.RESULTS:cPTFE alone and cPTFE-EHA gel was found to provide better functional recovery and nerve regeneration compared with primary repair only. In the macroscopic evaluation, the cPTFE-EHA gel was found to have no negative effect on wound healing and, despite increasing extra-neural scar tissue and adhesions, it had no negative effect on nerve function; in addition, it facilitated functional recovery.CONCLUSIONS:Compared with the cPTFE application alone, the application of perineural cPTFE-EHA gel during peripheral nerve surgery appeared to provide better functional recovery without causing any significant changes in epineural and extraneural scar tissue formation.     

Rupture of guide wire during percutaneous transluminal coronary angioplasty, a case report

The rupture of the guide wire is a very uncommon complication that may produce important consequences as occlusion of the artery of systemic embolism. The management of this event may be interventional or conservative, depending on the clinical situation of the patient and the position of the guide wire inside vessel. Here we present a case that we decided to leave the fragment in the artery. The retained filament and the coronary stenotic lesion was stented successfully.     

Venous sinus thrombosis after Proteus vulgaris meningitis and concomitant Clostridium abscess formation

A 19-y-old woman presented with Proteus vulgaris meningitis as a complication of chronic otitis media. Despite treatment with ceftazidime and amikacin no clinical improvement was observed. Cranial MRI revealed right-sided mastoiditis/otitis media and venous sinus thrombosis. After mastoidectomy, repeat cranial MRI demonstrated abscess formation in the venous sinuses. The abscess was drained. Clostridium spp. was isolated from the abscess culture.     

An unusual primary left ventricular hydatid cyst complicated by cardiac tamponade and mitral regurgitation--a case report

Cardiac involvement in hydatidosis is rare but because of potentially lethal complications, its recognition is of great importance. The authors present a 55-year-old woman admitted to the clinic with cardiac tamponade and moderate mitral regurgitation caused by a hydatid cyst located at the inferoposterior wall of the left ventricle.     

Serum leptin levels in gastric cancer patients and the relationship with insulin resistance

Introduction

Serum leptin levels have been examined in various cancers, with conflicting results. However, there is limited information regarding serum leptin levels and insulin resistance in gastric cancer patients. Therefore, we aimed to investigate serum leptin levels, performance status, insulin levels and insulin resistance in patients with gastric cancer. In addition, we examined the relationship between these measurements and leptin levels.

Material and methods

Thirty-nine patients with gastric cancer and 30 control subjects were enrolled in the study. Serum leptin, total protein, albumin, growth hormone, insulin and glucose levels were measured. The homeostasis model assessment (HOMA) was used to assess insulin resistance.

Results

Serum levels of insulin, glucose and growth hormone and insulin resistance were significantly lower in gastric cancer patients than controls (p < 0.05 for all). In the Pearson correlation analysis, insulin resistance was found to be significantly correlated with serum leptin levels in gastric cancer patients (r = 0.320, p = 0.047). We observed a significant negative correlation between performance status and insulin resistance in patients with cachexia (r = –0.512, p = 0.030), while no association was found in non-cachectic patients.

Conclusions

We concluded that serum leptin levels are significantly lower in gastric cancer patients. In addition, gastric cancer patients have decreases in insulin levels, insulin resistance and growth hormone levels. This study found a positive association between serum leptin levels and insulin resistance. Moreover, there is a negative association between serum leptin levels and growth hormone levels. Thus, low insulin and growth hormone levels may suppress the production of leptin in gastric cancer patients.
