Laparoscopic inguinal hernia repair: a rare case of colonic mesh migration

Inguinal hernia repair can be performed via either an open or laparoscopic technique. Use of a mesh to repair the abdominal wall defect is now common practice, leading to a reduction in hernia recurrence but also associated with a number of complications. We report a rare case of a 49-year old man who presented 3 years after laparoscopic hernia repair with right-sided abdominal pain and loose stools. Colonoscopy and computed tomography revealed a mesh and fixation devices within the lumen of the caecum and ascending colon. The mesh was successfully excised with primary closure of the bowel defect. This case highlights the importance of recognising mesh migration as a complication of hernia repair, a phenomenon which can lead to serious morbidity. We suggest that patients should be informed of this risk during the consent process, while further research is needed to investigate how this occurrence can be prevented.

Comparison among Different Culture Media for the Detection of Dermatophytes

Dermatophytes are a group of closely related fungi that have the capacity of invading the keratinized tissue of human to produce infections known as dermatophytosis which is commonly referred to as ringworm. Other than routine microscopy, different culture media are available for the detection of dermatophytes from patient's specimen. This cross sectional study was designed to evaluate the outcome of three different culture media and microscopy for the detection of dermatophytes from clinical samples. Skin, hair and nail samples from 84 clinically suspected cases of dermatophytosis who attended at OPD of Dermatology Department, Sylhet MAG Osmani Medical College Hospital, Sylhet, Bangladesh from July 2014 to June 2015 were screened by direct microscopic examination using potassium hydroxide (KOH) mount. All the samples were inoculated for culture in Sabouraud's Dextrose Agar (SDA), Dermatophytes Test medium (DTM) and Sabouraud's Cycloheximide Chloramphenicol Agar (SCCA). The percentage of samples positive by microscopy was 37.5%, whereas the rate of positivity by culture was 47.6% which showed that culture was more sensitive than microscopy for the diagnosis of dermatophytosis. The efficiency of SDA and SCCA was found to be almost equal. There was no statistically significant difference between SDA and DTM in primary isolation of dermatophytes, though isolation rate was slightly higher in DTM. Though direct examination by microscopy is an efficient screening technique, culture should be done for accurate diagnosis. As DTM is easy to evaluate even without handling the growth of culture in the laboratory, it is recommended to use as screening medium for the detection of dermatophytes.

Saline conditions alter morpho-physiological intensification in purslane (Portulaca oleracea l.)

In this study, primary investigations of selected cultivar of purslane named as Tall Green under articular salinity stress were evaluated to understand the basic concept of different mechanisms of physiological attributes which will play an important role for molecular and proteomic level research. The evaluation of morphological and physiological attributes under 0 mM (without salt addition) 100 mM and 200 mM salt stress changed dramatically. The results showed high salt stress at 200 mM significantly decreasing the morphological attributes and performance of leaves, stems, and roots. At moderate salt stress levels, 100 mM, the ratio of Fv/Fm slightly increased compared to high stress. In addition, salt stress significantly decreased the total chlorophyll content (chl a+b) at 200 mM. The relative water content percentage was high at 0 mM. Moreover, the electrolyte leakage (EL) significantly increased with increasing salinity stress compared to control 0 mM.

A rare case of haemorrhagic shock secondary to spontaneous rupture of a branch of the left colic artery and the right gastric artery

Spontaneous splanchnic artery rupture is associated with up to 70% mortality. Affected vessels are often aneurysmal, secondary to atherosclerosis. We report, to our knowledge, the only case of spontaneous rupture of a branch of the left colic artery and the right gastric artery, possibly secondary to vasculitis.

Measurement of Ascaris lumbricoides IgG antibody, associated risk factors and identification of serum biochemical parameters as biomarkers of pathogenicity: among patients with gastrointestinal complains in Pakistan

Soil transmitted helminths are causing significant morbidity worldwide and the most common infection is Ascaris lumbricoides in developing countries. The present study aimed to determine the immuno-epidemiological status of ascariasis among patients with gastrointestinal complaints and to identify the associated risk factors and eventual changes in serum biochemical parameters to reflect its pathogenicity. This study was conducted on 700 respondents aged between 5-45 years. A total of 356 patients participated in an enzymelinked immunosorbent assay (ELISA) study to determine anti-Ascaris IgG levels and biochemical parameters. The overall seroprevalence was 58.4%, with 100% sensitivity and 84.4% specificity of the assay. The infection was highest among the 21-28 year age group (14.0%), and ascariasis was found to be not significantly (P>0.05) different between the age groups. The results showed that the risk of ascariasis was significantly (P<0.05) increased in individuals who had no contact with soil (OR=4.6, 95% CI: 1.9-10.8), eating unwashed vegetables one month prior to the study (OR=2.7, 95% CI: 1.4-5.2), eating mixed food (OR=2.4, 95% CI: 1.2-4.7), drinking pressure pump water (OR=3.4, 95% CI: 1.9-6.1), and those who had no complain of vomiting (OR=3.1, 95% CI: 1.6-5.8) and nausea (OR=1.9, 95% CI: 1.1-3.2). The results showed significantly (P<0.05) elevated level of serum alanine aminotransferase, alkaline phosphatase, serum cholesterol, total protein and globulin in anti-Ascaris IgG positive cases than the control group. The study concluded that patients who visited health care centres with gastrointestinal complain were at higher risk of ascariasis as compared to other diseases. In conclusion epidemiological studies are needed to establish baseline data for public health authorities in order to plan and implement health education programs to reduce the impact of the disease.

Soft-tissue evidence of head injury in infants and young children: is CT head examination justified?

AIM

To determine whether it is justified to undertake a computed tomography (CT) examination of the head in children under 1 year of age who present with a bruise, swelling, or laceration of >5 cm following head injury in children presenting to a paediatric accident and emergency (A&E) department in the northwest of England. Further aims were to determine whether there was any justification for performing a CT head examination for children with soft-tissue injuries measuring <5 cm, or for children >1 year with evidence of soft-tissue injury, but without any other concerning feature.

MATERIALS AND METHODS

Children <3 years of age presenting with soft-tissue evidence of head injury between May 2011 and Oct 2014 and who subsequently underwent head CT were retrospectively identified from radiology requests. The CT images and clinical notes were used to identify those with skull fracture or intracranial haemorrhage and to determine whether the child was subsequently admitted or discharged from A&E.

RESULTS

Eighty-five CT head examinations met the criteria for inclusion. Of these, 45 examinations demonstrated skull fractures and four examinations identified intracranial haemorrhage. Thirty-eight requests included soft-tissue evidence of head injury as the sole reason indicated for CT head examination. Of these, 22 examinations demonstrated skull fractures and one examination identified intracranial haemorrhage.

CONCLUSION

Soft-tissue evidence of head injury as the sole reason for CT head examination appears to be justified in the present patient population. Furthermore, this study suggests that CT head examination should also be considered for children with soft-tissue injuries of <5 cm and for children aged between 1 and 3 years if identification of a skull fracture would alter the child's management.

Removal of Unusually Large Torpedo Sialolith from Wharton's Duct under Local Analgesia: A Case Report

Submandibular salivary gland system is commonly affected with sialolith (calculus) and victim suffers painful acute symptoms. Sialoliths usually are of 1-15mm in size. Although rarely giant sialoliths are seen, a giant torpedo sialolith of about 41mm × 9mm within the submandibular salivary duct is reported which was removed intraorally under local analgesia. Post-operatively, within six weeks salivation through duct was evidenced showing the process of re-establishment of salivary function.

Day surgery for achalasia cardia: Time for consensus?

INTRODUCTION

Laparoscopic Heller's myotomy (LHM) is the most effective therapy for achalasia of the oesophagus. Most case series of LHM report a length of hospital stay (LOS) >1 day. We present 14 years of experience of LHM to examine the safety and feasibility of LHM as a day case procedure.

METHODS

We retrospectively examined patients undergoing elective LHM for achalasia at our institution between 2000 and 2014. Demographics, episode statistics, prior investigations and interventions were collated. Outcomes, including LOS, complications and re-interventions, were compared for the periods before and after a consensus decision at our institution in 2008 to perform LHM as a day case procedure.

RESULTS

Sixty patients with a mean age of 41 ± 13 years were included, of whom 58% were male. The median LOS for all patients was 1 day (interquartile range [IQR] 0-2.25). Overall, LHM was performed as a day case in 27 (45%) cases, at 2/26 (7.7%) in the first period versus 25/34 (73.5%) in the second (p<0.01). There were no significant differences in age, gender or previous interventions between day surgery and non-day surgery groups. One patient required subsequent unplanned surgery, while six (10%) needed endoscopic treatment of recurrent symptoms within 12 months.

CONCLUSIONS

LHM can be performed safely as a day case procedure. Complication rates are low, with only a small proportion of patients requiring endoscopic treatment for symptom recurrence within 1 year.

The effect of urease and nitrification inhibitors on ammonia and nitrous oxide emissions from simulated urine patches in pastoral system: a two-year study

This field study evaluated the effects of applying a combination of urease (UI) and nitrification inhibitors (NI) on ammonia (NH3) and nitrous oxide (N2O) emission from urine patches, using zeolite, single superphosphate (SSP) and urea fertilizer as a carrier. The trial was conducted on a Typic Haplustepts silt loam soil, near Lincoln, Canterbury, New Zealand during 2009-11. The treatments in 2009 included: a control (no urine or inhibitor), urine alone at 600 kg N ha(-1), and urine with either double inhibitor (DI) a mixture (1:7 ratio w/w) of UI (N-(n-butyl) thiophosphoric triamide (nBTPT - trade name Agrotain®) and NI, dicyandiamide (DCD) or DCD alone at 10 kg ha(-1) using zeolite and SSP as carriers. In 2010 trials, both zeolite and urea were used as carriers for DI and DCD. DI-zeolite and DI-urea were equally effective and reduced the average NH3 losses from applied urine over two years by 34.6% in autumn and 40% in spring respectively. The nBTPT in DI-SSP was decomposed by the free acid produced during its dissolution and therefore increased NH3 emission as does DCD alone. DCD consistently increased NH3 emissions by 39% and 15.6% in autumn and spring respectively. Spring application resulted in NH3-N losses of 16.9% as a percentage of the total N applied compared to 8.4% in autumn. Over the two years, the DI reduced N2O emissions by 53% in autumn and 46% in spring over urine alone treatment; the equivalent reductions for DCD were 42% and 39% for autumn and spring, respectively. These results suggest that applying DI in autumn and spring using zeolite or urea carrier five days prior to grazing has the most potential to reduce NH3 and N2O losses from specific urination event than using DCD alone; and therefore warrants further research to improve its longevity.

Consultant Versus Trainee Laparoscopic Pyloromyotomy: Is there a Difference in Outcome?

Infantile hypertrophic pyloric stenosis (IHPS) is a common cause of vomiting in infants. IHPS was a condition with significant associated mortality until 1912 when ramstedt introduced the operative procedure pyloromyotomy. Since then, mortality rates have reduced significantly owing to early recognition, correction of associated biochemical abnormalities and operative treatment. More recently, the management of IHPS has been modified by the introduction of the laparoscopic pyloromyotomy, first described almost two decades ago.

Health-seeking behaviour of women selling sex in Lahore, Pakistan

The aim of this study was to describe the knowledge and health-seeking behaviour related to sexually transmitted infections (STIs) and abortion among women selling sex in Lahore, Pakistan. This was a cross-sectional, community-based, quantitative study. A total of 730 women selling sex were recruited by respondent-driven sampling. A pretested structured questionnaire was administered through face-to-face interviews. The median age of the participants was 30 years. Thirteen percent of the participants said it was common for them to have an abnormal vaginal discharge. Seventy-five percent of the participants recognized STIs as either leucorrhoea or AIDS. Sixty-five percent of the participants complained of having suffered from STI(s) in the six months preceding the survey, of whom 28% sought treatment. Women selling sex who reported consistent condom use were 1.5 times (95% confidence interval [CI]: 1.1–2.2) more likely to seek treatment than women who did not report consistent condom use. The level of knowledge about STIs remains low among women selling sex in Lahore, Pakistan, and health-seeking behaviour for the management of STIs and abortions is influenced by ability to pay and ease of access in the private sector.

Influence of pH, Precursor Concentration, Growth Time, and Temperature on the Morphology of ZnO Nanostructures Grown by the Hydrothermal Method

We investigated the influence of the pH value, precursor concentration (C), growth time and temperature on the morphology of zinc oxide (ZnO) nanostructures. The pH of the starting solution was varied from 1.8 to 12.5. It was found that the final pH reaches an inherent value of 6.6 independently of the initial pH solution. Various ZnO structures of nanotetrapod-like, flower-like, and urchin-like morphology were obtained at alkaline pH (8 to 12.5) whereas for pH solution lower than 8 rod-like nanostructures occurred. Moreover, we observed the erosion of the nanorods for a pH value less than 4.6. By changing the concentrations the density and size were also varied. On going from a high (C>400 mM) to lower (C<25 mM)C, the resulted ZnO nanostructures change from a film to nanorods (NRs) and finally nanowires (NWs). It was also found that the length and diameter of ZnO NRs follow a linear relation with time up to 10 hours, above which no further increase was observed. Finally the effect of growth temperature was seen as an influence on the aspect ratio.

Effect of dietary concentrate on rumen fermentation, digestibility, and nitrogen losses in dairy cows

The objective of this experiment was to investigate the effect of level of dietary concentrate on rumen fermentation, digestibility, and N losses in lactating dairy cows. The experiment was a replicated 3x3 Latin square design with 6 cows and 16-d adaptation periods. Ruminal contents were exchanged between cows at the beginning of each adaptation period. Data for 2 of the diets tested in this experiment are presented here. The diets contained (dry matter basis): 52% (LowC; control) and 72% (HighC) concentrate feeds. Crude protein contents of the diets were 16.5 and 16.4%, respectively. The HighC diet decreased ruminal pH and ammonia concentration and increased propionate concentration compared with LowC. Acetate:propionate ratio was greater for LowC than for HighC. Rumen methane production and microbial protein synthesis were unaffected by diet. Dry matter intake was similar among diets, but milk yield was increased by HighC compared with LowC (36.0 and 33.2 kg/d, respectively). Milk fat percentage and yield and total-tract apparent NDF digestibility were decreased by HighC compared with LowC. More ruminal ammonia N was transferred into milk protein with HighC than with LowC. Urinary N excretion, plasma urea N, and milk urea N concentration were not affected by diet. The ammonia emitting potential of manure was similar between LowC and HighC diets. Increased concentrate proportion in the diet of dairy cows resulted in reduced ruminal ammonia concentration and enhanced ammonia utilization for milk protein synthesis. These effects, however, did not result in reduced urinary N losses and only marginally improved milk N efficiency. Increasing dietary concentrate was not a successful strategy to mitigate enteric methane production and ammonia emissions from manure.

Stable White Light Electroluminescence from Highly Flexible Polymer/ZnO Nanorods Hybrid Heterojunction Grown at 50 degrees C

Stable intrinsic white light-emitting diodes were fabricated from c-axially oriented ZnO nanorods (NRs) grown at 50 degrees C via the chemical bath deposition on top of a multi-layered poly(9,9-dioctylfluorene-co-N-(4-butylpheneylamine)diphenylamine)/poly(9,9dioctyl-fluorene) deposited on PEDOT:PSS on highly flexible plastic substrate. The low growth temperature enables the use of a variety of flexible plastic substrates. The fabricated flexible white light-emitting diode (FWLED) demonstrated good electrical properties and a single broad white emission peak extending from 420 nm and up to 800 nm combining the blue light emission of the polyflourene (PFO) polymer layer with the deep level emission (DLEs) of ZnO NRs. The influence of the temperature variations on the FWLED white emissions characteristics was studied and the devices exhibited high operation stability. Our results are promising for the development of white lighting sources using existing lighting glass bulbs, tubes, and armature technologies.
