Continuous figure-of-eight suturing in upper and lower gastrointestinal anastomosis

INTRODUCTION

The optimal technique for gastrointestinal anastomosis is controversial. The three most popular techniques are two layers, one layer and the stapling method. However, there is no universal agreement on the best technique. The aim of this study was to evaluate the safety, feasibility, and efficacy of continuous figure-of-eight suturing in gastrointestinal anastomosis.

METHODS

This was a retrospective study of 170 patients who underwent gastrointestinal anastomosis using continuous figure-of-eight suturing for the first layer and continuous seromuscular suturing for the second layer from August 1993 to January 2006. All operations were performed by a single consultant surgeon. We assessed each anastomosis by checking the integrity, vascularity and patency, and also ensuring tension-free status. Postoperatively, patients were managed by routine care of intravenous fluids and nasogastric tube until they had active bowel sounds and started absorbing. Imaging was arranged for patients who developed clinical signs and symptoms of leak.

RESULTS

170 patients underwent gastrointestinal anastomosis by continuous figure-of-eight suturing for different pathologies over a two-and-a-half-year period. There were 92 (54.1 percent) men and 78 (45.9 percent) women. The mean age of the patients was 56 (range 20-88) years. The median follow-up was 74 months. There were 124 (72.9 percent) small bowel anastomosis and 46 (27.1 percent) large bowel anastomosis. An important complication after gastrointestinal anastomosis was leakage, which was reported in three (1.8 percent) patients. One of them had gastric cancer, one had Crohn's disease and one had intestinal ischaemia. No mortality was reported in relation to anastomotic failure. Two (1.2 percent) patients developed stenosis and 15 (8.8 percent) patients died because of progression of their disease or other pathologies during the follow-up.

CONCLUSION

Continuous figure-of-eight suturing is a simple, easy to learn, safe and satisfactory upper and lower gastrointestinal anastomosis technique.

Venous air embolism during the use of a Nd YAG laser

We report a case of a 47-year-old female who suffered a cardiac arrest during sub-mucosal diathermy of the inferior turbinate using a Nd YAG laser. The possible causes of the cardiac arrest are discussed. Venous air embolism due to Nd YAG laser was thought to be the most likely cause in this case. Although venous air embolism has previously been reported during nasal sinus surgery and choanal atresia when using a Nd YAG laser, the occurrence of this complication during a relatively minor surgical procedure has not previously been reported. It is important, therefore, to raise the awareness of this life threatening complication during use of a Nd YAG laser regardless of the duration of surgery. We recommend the use of appropriate methods and techniques to avoid this life threatening complication during the use of Nd YAG laser even for relatively short procedures.

Patients' satisfaction with the nurse-led aural care clinic

BACKGROUND

The necessity of decreasing costs while maintaining a high standard of clinical care has led to the expansion of the role of nurses in recent years. To this end, nurse-led clinics are becoming increasingly common in otolaryngology. The aims of this cross sectional survey were to assess patients' satisfaction with this nurse-led aural care clinic.

METHOD

Patients attending this clinic were requested to fill in an anonymous questionnaire. Data was collected for 12 weeks between January and April, 2007.

RESULTS

Forty-four questionnaires were completed satisfactorily (44/50 = 88%). In response to the presenting complaint, the nurse gave verbal advice (25), discussed with a doctor (10) or arranged a doctor review (9). Forty patients were very satisfied and 4 patients were satisfied with the overall care in the clinic.

CONCLUSION

Combining medical and nursing efforts can provide efficient use of limited time resource in NHS. Nurse-led clinics are cost effective and help reduce the waiting time, for outpatient clinics.

Epidemiology of the breast cancer patients registered at Institute of Radiotherapy and Nuclear Medicine, Peshawar, Pakistan

In Pakistan, malignant diseases are increasing day by day, but no epidemiological cancer study on large scale has been designed. The main objective of this study was to provide a baseline data on frequency, morphological types, gender and age distribution etc., of breast cancer in North-West Frontier Province and Federally Administered Tribal Areas of Pakistan, and to compare it with the published data. In this context, 2134 breast cancer patients (2059 female and 75 male) registered at Institute of Radiotherapy and Nuclear Medicine, Peshawar from 1995 to 2001, were studied. Crude incidence, standardized incidence ratios (SIR, world) and age-specific incidence rates (ASIR) were determined both for male and female patients. Same morphological distribution was found in both genders. Moreover, breast cancer was found to be the most common malignancy among the women (96.49%). Male to female breast cancer ratio was found to be 3.5 times higher than the reported data. The highest ASIR of approximately 10.6/100,000 per year among women was observed in the age group of 55-59 years. In men, the highest ASIR of 0.84/100,000 per year was observed in the age group of 65-69 years. The SIR (world) for women was 3.15/100,000 per year, while for male this was 0.13/100,000 per year.

National survey of the management of eye emergencies in the accident and emergency departments by senior house officers: 10 years on--has anything changed?

OBJECTIVE

To assess changes in basic ophthalmic training of accident and emergency (A&E) senior house officers (SHOs) in the last 10 years, their own perceived level of confidence and the availability of appropriate equipment in their departments.

METHODS

A standardised structured questionnaire from a telephone survey carried out in 1993 was used. One SHO from each A&E department listed in the British Association of Emergency Medicine directory of 2003 was chosen at random and interviewed.

RESULTS

168 A&E departments were contacted and 133 SHOs were successfully interviewed (response rate 79.2%). The number of A&E departments with a slit lamp increased by 25.7% from 1993, and slit lamp training increased by 21%. There was no significant change in the prevalence of training in the management of eye emergencies (74.0% in 1993 vs 77.4% in 2003) and the proportion of SHOs who felt confident in dealing with these cases was unchanged.

CONCLUSIONS

A&E departments are better equipped with slit lamps 10 years on, and staff are being trained to use them. This has unfortunately not improved the confidence levels in dealing with eye emergencies, reflecting the lack of adequate basic ophthalmic training for A&E SHOs. Recent changes in postgraduate medical training could provide a platform to bring about the changes required.

Ultrabroadband polarization analysis of terahertz pulses

We describe the characteristics of a sensitive photoconductive detector that simultaneously measures orthogonal electric field components of electromagnetic transients with bandwidths up to 30 THz. The device consists of an As(+) implanted GaAs photoconducting region at the centre of a pair of perpendicular bow-tie antennas. The performance is illustrated by studies of optical rectification in GaSe, retardation in a birefringent polymer film and THz emission from impulsively excited optical phonons in GaN.

Glucose tolerance in a rural population of Bangladesh

CONTEXT

The prevalence of type 2 diabetes is increasing in the Bangladeshi population. However, there is little information available on the prevalence of glucose intolerance, ie, type 2 diabetes, impaired glucose tolerance, and impaired fasting glucose.

AIMS

The main aim of this study is to determine the prevalence of different categories of glucose intolerance and their relationship with different anthropometric and demographic characteristics.

SETTINGS AND DESIGN

This cross-sectional study was performed in a rural area of Bangladesh.

MATERIALS AND METHODS

A random sample of 5000 persons aged >/= 20 years was included in this study. Fasting blood glucose was measured in 3981 individuals and 2-h post-glucose blood glucose was measured in 3954 subjects after the known cases of diabetes (n = 27) were excluded. Height, weight, waist and hip circumference, and blood pressure were measured.

STATISTICAL ANALYSIS

Pearson Chi-squared test and correlation test were used for analysis as appropriate.

RESULTS

The prevalence of impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and diabetes (DM) were 1.3, 2.0, and 7.0%, respectively. IFG, IGT, and IFG + IGT were more prevalent in females. Age showed a significant positive relationship with increasing levels of glucose intolerance. Body mass index, waist circumference, and waist-to-hip ratio were higher in the glucose-intolerant group than in the normal glucose tolerance (NGT) group. There was a positive correlation between FBG and 2-h BG in NGT and DM subjects.

CONCLUSION

The FBG value identified more people with glucose intolerance than the 2-h BG. These findings will help developing diabetes preventive strategy in rural populations.

Prevention of trocar site incisional hernia following laparoscopic ventral hernia repair

BACKGROUND AND OBJECTIVES

Trocar-site incisional hernia following laparoscopic ventral hernia repair is reported to have a relatively high incidence. The main reasons are trocar diameter and design, pre-existing fascial defects, and some operation- and patient-related factors. The aim of this article to show a new technique of ventral hernia repair that could prevent trocar site incisional hernia.

METHODS

After establishing the pneumoperitoneum, three 5-mm ports are inserted in positions according to the site and size of the hernia. The procedure begins by dissection of the adhesions of bowel loops or omentum (if any) from the hernia to clear a good margin for mesh coverage. Then a single 10-mm to 15-mm port (mesh insertion port) is inserted in the center of the ventral hernia depending on the size of the mesh. The mesh is fixed in position with a 5-mm tacker. The peritoneum and underlying superficial fascia are carefully closed before closing the skin.

RESULTS

A total of 35 patients were recruited for this method. The mean hospital stay was 1.5 days, the mean age was 50.35 years and the mean operative time was 40 minutes. In all patients, 10x15-cm ePTFE was used. No single incidence of trocar-site incisional hernia occurred during a mean follow-up of 2 years. Three (8.57%) patients developed complications and no mortality was reported.

CONCLUSION

The mesh introduction through the port, which is situated at the center of the hernia defect is a simple, cost-effective technique and will prevent trocar-site incisional hernia.

Decline in HIV prevalence among women of childbearing age in Moshi urban, Tanzania

The objective of this study was to describe trends over time in HIV prevalence, sexually transmitted infections (STIs) and sexual behaviour among women in Moshi urban, Tanzania. Two cross-sectional studies were conducted in 1999 and in 2002-04 among women attending three primary health-care clinics. They were interviewed and screened for HIV and STIs. There was a significant decrease in HIV prevalence (11.5-6.9%). The decline was greatest among women aged 15-24 years. Syphilis, trichomoniasis, bacterial vaginosis, genital ulcers and reported STI symptoms also decreased significantly over the three-year inter-survey period. The proportion of women reporting casual sex decreased and knowledge of STI symptoms and health-care seeking behaviour improved. Herpes simplex virus type 2, genital warts, age at sexual debut, age at first pregnancy and condom use remained unchanged. In conclusion, decline in curable STIs and casual sex partners may partly explain the observed decline in HIV seroprevalence. Both STIs and sexual behaviour should be monitored in HIV sentinel surveillance. There remains a gap between knowledge of preventive behaviour and actual preventive practices.

Food insufficiency in rural Kilimanjaro, Tanzania

OBJECTIVES

To estimate the prevalence of reported food insufficiency associated socio-demographic factors and health indicators in rural Tanzania.

DESIGN

A cross-sectional study.

SETTING

A rural community in Kilimanjaro, Tanzania.

SUBJECTS

Eight hundred and ninety nine individuals aged 15-36 years. A structured questionnaire was administered to collect information on socio-demographic factors, health indicators and food insufficiency. Participants were tested for HIV-1 using saliva samples.

RESULTS

The prevalence of food insufficiency was 25.3% with no sex difference. After controlling for potential confounders age (Adjusted Odds Ratio [AOR] = 1.05; 95% Confidence Interval [CI]: 1.02-1.08), low education level (AOR = 4.73; CI: 1.30-17.11), being a peasant (AOR = 2.29; CI: 1.04-5.04), poor self-rated health status (AOR = 4.35; CI: 1.71-11.00) and having health problems (AOR = 2.23; CI: 1.21-4.08) were associated with food insufficiency among women but not men. In unadjusted analysis, women with food insufficiency had over twice the odds of testing HIV positive although the association did not reach statistical significance (AOR = 2.12; CI: 0.87-5.19) in adjusted analysis.

CONCLUSIONS

Food insufficiency was prevalent in rural Tanzania. It was associated with sociodemographic factors and health indicators among women but not men. Our findings suggest that food insufficiency may play a role in increasing vulnerability to HIV infection particularly among women however; more research is needed to explore further this relationship.

Prevalence of depression and diabetes: a population-based study from rural Bangladesh

AIMS

To determine the extent of depressive symptoms in a rural community of Bangladesh and its association with newly recognized diabetes.

METHODS

Depressive symptoms were assessed in 184 newly diagnosed diabetic subjects and 768 randomly selected individuals without diabetes. The Montogomery and Aasberg Depression Rating Scale (MADRS) was used to assess depressive symptoms. A structured interview was performed to obtain socio-demographic and economic information and anthropometric measures were collected. Fasting plasma glucose was measured by the HemoCue glucose analyser.

RESULTS

Twenty-nine percent of male and 30.5% of female participants with diabetes and 6.0% of male and 14.6% of female subjects without diabetes had depressive symptoms rating > or = 20 on the MADRS. An association between depressive symptoms and diabetes was found (P < 0.01). After controlling for potential confounding factors including age, gender, fasting plasma glucose > 7.0 mmol/l and waist-hip ratio, the association of depression with diabetes remained significant.

CONCLUSIONS

An unexpectedly high level of unrecognized depressive symptoms was found in the general rural population of Bangladesh. These are among the first data to suggest that depressive symptoms in this culture are common, especially in women. Depression is particularly common in those with diabetes. Psychiatric intervention may be necessary in addition to lifestyle changes to prevent the exponential increase in the occurrence of Type 2 diabetes. In addition, a common approach including psychiatric treatment in diabetes care may be necessary to achieve improved glycaemic control in this population.

Renal function among cancer patients with bone metastases treated with zoledronic acid in a real world setting

19540

Background: Zoledronic acid (ZA) is a bisphosphonate that reduces skeletal related events (SREs) in cancer patients (pts) with bone metastases but can impact renal function in some pts. This retrospective study examined serum creatinine (sCr) elevations and subsequent treatment changes among pts receiving ZA in community based medical practices. Methods: Data were obtained from the Varian Medical Oncology database of electronic medical records from 17 US oncology practices. Cancer pts with bone metastases and at least one ZA infusion in 2002–06 were followed; all available sCr levels were examined. SCr measurements ≤4 weeks after a ZA infusion were considered levels while on ZA. Elevated sCr was defined as an increase over baseline of ≥0.5 mg/dL or a doubling from baseline for pts with baseline levels <1.4 mg/dL (or ≥1.0 mg/dL for higher baseline levels). Pts with a sCr elevation on ZA were followed to observe changes in ZA dosing and sCr. Results: The study included 875 pts (318 with breast cancer, 131 lung, 154 prostate, 23 multiple myeloma, and 249 other or unknown cancer) with ≥1 sCr level during baseline and ≥1 (median 6) while on ZA. Median age was 66, 41% were male, and 90% had baseline sCr under 1.4 mg/dL. Pts received a median of 6 ZA infusions. SCr elevations occurred in 87 pts (10%), at a median of 19 weeks (range 0.6–126) after the start of ZA. Pts with baseline sCr over 2.0 mg/dL were more likely to experience an elevation (11 pts, 33%). Following the elevated sCr, 37 pts (43%) discontinued ZA; dose reductions and delays were infrequent. Among 49 pts who remained on ZA after elevated sCr and had further sCr while on ZA, 20 (41%) returned to within 10% of baseline, at a median of 7 weeks (range 0.3–31) after the first measured elevation. The proportion returning to normal is a conservative estimate given limited follow-up sCr data. Conclusions: The observed incidence of elevated sCr of 10% in this community based study is similar to clinical trials. Most pts either discontinued ZA or returned to baseline levels despite continued ZA treatment. Few practitioners adhered to recommendations to withhold ZA until levels return to within 10% of baseline.

Prevention of type 2 diabetes: a review

One of the major public health challenges of the 21st century is type 2 diabetes. WHO estimates that by 2025 as many as 200-300 million people worldwide will have developed the disease. A distressing increase in children is perhaps the most alarming sign of something going wrong. Roughly half of the risk of type 2 diabetes can be attributed to environmental exposure and the other half to genetics. Central themes for prevention are the risk factors overweight, sedentary lifestyle, certain dietary components and perinatal factors. Overweight is the most critical risk factor, and should be targeted for prevention of type 2 diabetes especially among children and youths. Ethnicity and perinatal factors are also worth considering. Today we know that prevention helps. In the US Diabetes Prevention Programme for high risk individuals, there was a 58% relative reduction in the progression to diabetes in the lifestyle group compared with the controls. Within the lifestyle group, 50% achieved the goal of more than 7% weight reduction, and 74% maintained at least 150 min of moderately intense activity each week. This review discusses different forms of prevention, and proposes first of all to target people with Impaired Glucose Tolerance with increasing activity and altering dietary factors. And secondly, population-based measures to encourage increased physical activity and decreased consumption of energy-dense foods are important, and may target school children and young people, certain ethnic groups and women with gestational diabetes.

Stent angioplasty: an effective alternative in selected infants with critical native aortic coarctation

Management of native aortic coarctation during early months of life poses therapeutic challenges, and there is no consensus among medical professionals regarding a management plan. Much can be argued about the benefits, limitations, and/or complications of transcatheter versus surgical intervention in such cases. Occasionally, the complexity of the lesions limits management options. Therefore, each patient requires individual management decisions because there is no one therapeutic plan that satisfies all patients. In this report, four critically ill infants who had complex native coarctation are presented. Surgical repair was not possible because of relative contraindications. The patients underwent transcatheter stent implantation (six procedures and seven stents) as a nondefinitive procedure with acceptable results. Three patients improved. One patient did not survive, mainly due to other major complications. Multiple reexpansions of the stents were carried out when indicated. After a mean follow-up of 45 months (range, 41-49), the three survivors were doing fine and had gained an average weight of 9.7 kg (range, 6.6-13.3). At the time of reporting, the relative contraindications no longer exist and the final surgical repair can be carried out. Our experience suggests that in certain situations and in critically ill infants with complex form of coarctation, stent angioplasty can be used as a life-saving palliative procedure. Further reexpansions can be done when required. This may serve as a bridge to major surgical repair in the future.

New germline mutations in the hypervariable minisatellite CEB1 in the parents of children with leukaemia

Gardner and co-workers advanced the hypothesis that the Seascale leukaemia cluster could have been caused by new mutations in germ cells, induced by paternal preconceptional irradiation (PPI) exposure at the Sellafield nuclear installation. Since evidence has shown that PPI can increase the de novo germline mutation rate in hypervariable minisatellite loci, we investigated the hypothesis that sporadic childhood leukaemia might be associated with an increased parental germline minisatellite mutation rate. To test this hypothesis, we compared de novo germline mutation rates in the hypervariable minisatellite locus, CEB1, in family trios (both parents and their child) of children with leukaemia (n=135) compared with unaffected control families (n=124). The majority of case and control germline mutations were paternal (94%); the mean paternal germline mutation rates of children with leukaemia (0.083) and control children (0.156) were not significantly different (odds ratio, 95% confidence interval: 0.50, 0.23–1.08; P=0.11). There were no significant differences in case and control parental allele sizes, case and control germline mutation progenitor allele sizes (2.74 vs 2.54 kb; P=0.56), case and control mutant allele sizes (2.71 vs 2.67 kb; P=0.90), mutant allele size changes (0.13 vs 0.26 kb; P=0.10), or mutational spectra. Within the limitation of the number of families available for study, we conclude that childhood leukaemia is unlikely to be associated with increased germline minisatellite instability.
