Semen quality and reproductive endocrinal function related to blood lead levels in infertile painters

Lead causes male reproductive impairment among painters, but information is still limited. Therefore, the effect of lead on semen quality and reproductive endocrinal function in those patients was investigated. A case series of 27 infertile painters were subjected to semen analysis, measuring of blood lead level (PbB) and serum levels of endocrinal parameters including follicle‐stimulating hormone (FSH), luteinising hormone (LH), testosterone (T) and prolactin (PRL). Significantly lower sperm count and motility were found in those with duration of exposure (≥15 years), but no significant difference was found for PbB and serum levels of FSH, LH, PRL and T. A significant negative correlation between PbB and spermatic count and motility was observed, while there was no significant correlation between PbB and all endocrinal parameters. Patients with PbB ≥ 20 μg dl^?1 showed a significant decrease in sperm motility and increase in testosterone alone among all measured hormones. But the observed decrease in sperm count did not reach a significant level. It is concluded that infertile painters are at risk of lead‐related influence on semen quality, especially sperm motility and increased testosterone level without significant affection of other reproductive endocrinal parameters.     

Glutathione‐S‐transferase‐oxidative stress relationship in the internal spermatic vein blood of infertile men with varicocele

This study aimed to assess glutathione‐S–transferase (GST) enzyme‐ oxidative stress (OS) relationship in the internal spermatic vein (ISV) of infertile men associated with varicocele (Vx). Ninety five infertile oligoasthenoteratozoospemic (OAT) men associated with Vx were subjected to history taking, clinical examination and semen analysis. During inguinal varicocelectomy, GST, malondialdehyde (MDA) and glutathione peroxidase (GPx) were estimated in the blood samples drawn from ISV and median cubital veins. The mean levels of GST, GPx were significantly decreased and the mean level of GPx was significantly increased in the ISV compared with the peripheral blood. The mean level of GST and GPx in the ISV was significantly decreased, and the mean level of MDA was significantly increased in Vx grade III compared with Vx grade II cases. There was nonsignificant difference in the mean level of GST in the ISV in unilateral Vx cases compared with bilateral Vx cases. There was significant positive correlation of GST with sperm count, sperm motility, GPx and significant negative correlation with sperm abnormal forms, MDA. It is concluded that ISV of infertile men associated with Vx has decreased levels of GST compared with peripheral venous circulation that is correlated with both OS and Vx grade.     

Adding a custom made pressure release valve during air enema for intussusception: A new technique

Background:

Non-surgical reduction remains the first line treatment of choice for intussusception. The major complication of air enema reduction is bowel perforation. The authors developed a custom made pressure release valve to be added to portable insufflation devices, delivering air at pressures accepted as safe for effective reduction of intussusception in children under fluoroscopic guidance. The aim of this study was to develop a custom made pressure release valve that is suitable for the insufflation devices used for air enema reduction of intussusception and to put this valve into regular clinical practice.

Materials and Methods:

An adjustable, custom made pressure release valve was assembled by the authors using readily available components. The valve was coupled to a simple air enema insufflation device. The device was used for the trial of reduction of intussusception in a prospective study that included 132 patients.

Results:

The success rate for air enema reduction with the new device was 88.2%. The mean pressure required to achieve complete reduction was 100 mmHg. The insufflation pressure never exceeded the preset value (120 mmHg). Of the successful cases, 58.3% were reduced from the first attempt while 36.1% required a second insufflation. Only 5.55% required a third insufflation to complete the reduction. In cases with unsuccessful pneumatic reduction attempt (18.1%), surgical treatment was required. Surgery ranged from simple reduction to resection with a primary end to end anastomosis. No complications from air enema were recorded.

Conclusions:

The authors recommend adding pressure release valves to ensure safety by avoiding pressure overshoot during the procedure.Key words: Air enema, intussusception, pneumatic, pressure release, reduction, safety, valve     

Kawasaki disease in Oman--a clinical study

A total of 39 patients were diagnosed to have Kawasaki disease by the standard diagnostic criteria, at The Royal Hospital, Muscat, Oman, during the period January 1995 to August 2002. A retrospective analysis of the case records of the patients with the diagnosis of Kawasaki disease was done. The results of the clinical features and the laboratory manifestations of the patients, who are from the Middle East region, are presented. The peak age at presentation was 6-30 months, mean 29 months. Peak months of the occurrence of the disease were March and October. Oral lesions were found in all cases. The mean duration of hospital stay for these patients was 8.5 days, range 2-21 days. The total duration of fever ranged from 6 to 21 days, with a mean value of 9.4 days. An elevated erythrocytic sedimentation rate (ESR; 91.7 per cent) and a raised C-reactive protein (C-RP; 92.3 per cent) were the most significant laboratory findings. Echocardiographic abnormalities were found in 25 per cent of cases, the incidence of coronary artery involvement (dilatation with or without stenosis) being 12.5 per cent. High dose intravenous immunoglobulin (2 g/kg over a 12-h period) plus aspirin therapy was found to be safe and effective in patients with Kawasaki disease.     

Comparison of immediate postoperative pain after transvaginal versus traditional laparoscopic cholecystectomy

Background

Transvaginal cholecystectomy (TVC) is the most common natural orifice transluminal surgery (NOTES) performed in women, yet there is a paucity of data on intraoperative and immediate postoperative pain management. Previous studies have demonstrated that NOTES procedures are associated with less postoperative pain and faster recovery times. This study analyzes intraoperative and postoperative opioid use for TVC compared with traditional four-port laparoscopic cholecystectomies (LCs).

Methods

This is a retrospective analysis of consecutive TVC and LC female patients between August 2009 and August 2012 in an academic institution. We compared demographics, intraoperative and postoperative opioid use and times in the operating room (OR) and in the post anesthesia care unit (PACU).

Results

A total of 68 TVC and 67 LC patients were included in this study. The TVC and LC groups were similar in terms of age (both 41 years) and body mass index (29 and 31 kg/m², respectively). The intraoperative preparation, surgical, and emergence times were significantly longer for the TVC than for the LC (p ≤ 0.01). Compared with the LC group, the intraoperative opioid requirement was significantly greater (TVC 27 mg vs. LC 25 mg; p = 0.003), but after adjusting for anesthesia time, the difference in OR opioid consumption became non-significant (p = 0.08). The PACU opioid requirement (TVC 2.5 vs. LC 5 mg; p = 0.04) was significantly lower for the TVC group, and a greater proportion of patients did not need any pain medications (TVC 38 % vs. LC 21 %; p = 0.04), compared with the LC group. The average PACU pain scores were not significantly different between the groups (p = 0.45).

Conclusion

TVC patients did not experience more pain than LC patients. Although the average pain scores of TVC patients did not differ from those of the LC patients, TVC patients did require less pain medication in the PACU.     

Heller's myotomy without fundoplication: a series of 123 patients

INTRODUCTION: Surgical treatment of achalasia of lower oesophageal sphincter is Heller's myotomy, usually associated with a fundoplication due to an high risk of postoperative gastro-oesophageal reflux. The value of this fundoplication is discussed. The aim of this study was to evaluate retrospectively the results of Heller's myotomy without fundoplication but performed according to a precise technique preventing postoperative reflux. PATIENTS AND METHODS: Between 1975 and 1999, 123 patients underwent Heller's myotomy without systematic fundoplication. Diagnosis of achalasia was performed clinically and confirmed by investigations: baryum meal, fibroscopy and manometry. Myotomy was performed through an abdominal approach in 117 (95%) patients. Dissection preserved fixity of abdominal oesophagus in all cases, particularly its posterior meso. Myotomy was performed on abdominal oesophagus but not below the cardia. Posterior fundoplication was associated in 2 patients. RESULTS: One patient (0,8%) died from massive aspiration. Morbidity (1,6%) consisted in one peritonitis and one postoperative occlusion. At follow-up (mean = 5 years; range: 1-20), functional results were satisfying (excellent and good) in 112 (92%) patients. Seven patients (6%) developed postoperative reflux, including one who need surgical treatment. Dysphagia persisted in 3 patients (2%) who had to be reoperated. CONCLUSION: Results of this series show that systematic fundoplication is not necessary in Heller's myotomy for achalasia of lower oesophageal sphincter.
