Percentage Incidences of Bacteria in Mahseer (Tor putitora), Silver carp (Hypophthalmichthys molitrix) Fish Collected from Hatcheries and Local Markets of District Malakand and Peshawar of Khyber Pakhtunkhwa, Pakistan

Abstract Fish is the main source of animal protein for human diet. The aim of this study was to find out prevalence of pathogenic bacteria of two selected economically important fish of Pakistan namely Mahseer (Tor putitora) and Silver carp (Hypophthalmichthys molitrix). Live fish samples from hatcheries and dead fish samples from different markets of study area were randomly collected. The fish samples were analyzed for isolation, identification and prevalence of bacteria. The isolated bacteria from study fish were identified through biochemical test and about 10 species of pathogenic bacteria were identified including the pathogenic bacteria to human and fish namely, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus iniae, Serratia spp. Citrobacter spp. Stenotrophomonas spp. Bacillus spp. and Salmonella spp. The bacterial percentage frequency of occurrence in Silver carp and Mahseer fish showed Pseudomonas aeruginosa 21.42%, Staphylococcus epidermidis 17.85%, Escherichia coli 11.90%, Staphylococcus aureus 9.52%, Citrobacter spp. 9.52%, Serratia spp. 8.33%, Streptococcus iniae 7.14%, Stenotrophomonas spp. 5.95%, Bacillus spp. 4.76% and Salmonella spp. 3.57%. The study revealed that Fish samples of Mahseer and Silver carp that were collected from markets have found more isolates (10 bacterial species) than did the fresh fish pond samples (03 bacterial species) of hatcheries. The occurrence of pathogenic bacteria in study fish showed risk factor for public health consumers.

Reattachment of coronal fragment using fiber reinforced post.

Anterior crown fractures are a common form of injury that mainly affects children and adolescents due to their position in the oral cavity especially in the maxillary arch. Reattachment of original tooth fragment to the fractured tooth forms a relatively quick, biologic and esthetic restoration. A 28 years old male reported to the Department of conservative dentistry & endodontics with a complex crown fracture of 21 and 22 one day after the trauma had occurred. Following endodontic treatment, a glass fibre post was used to increase retention and distribute stresses along the tooth. The dental restoration was completed using the original fragment and a dual cure resin composite. Clinical and radiographic examination at 3, 6 & 11 months recall showed the glass fiber post and restoration was in place, indicating the success of the treatment in maintaining the fractured tooth.

Minimally invasive surgery training in the Caribbean: a survey of general surgical residents and their trainers / Entrenamiento de cirugía mínimamente invasiva en el Caribe: encuesta a los residentes de cirugía general y sus entrenadores

BACKGROUND: There has been debate on the feasibility of incorporating minimally invasive surgery (MIS) into surgical practice in developing countries due to resource and training limitations. Our study establishes the current and desired state of MIS training in surgical residency programmes in the Caribbean. METHODS: An adapted version of a previously administered questionnaire was issued to surgeons and residents involved in the general surgical residency programme of The University of the West Indies in Barbados, Jamaica and Trinidad and Tobago. Data were analysed using the Statistical Package for the Social Sciences, version 17.0. RESULTS: The questionnaire was sent to 41 surgeons and 41 residents with a 65% response rate. Most residents had performed less than 25 basic laparoscopic procedures. Up to 82% of residents felt that they would be unable to perform advanced laparoscopic procedures due to lack of training. The principal negative factors influencing MIS training included lack of operating room time, lack of equipment and lack of preceptor expertise. Both surgeons (83.4%) and residents (93.4%) strongly felt that a surgical skills laboratory would be helpful for the acquisition of MIS skills. Both surgeons (85.7%) and residents (100%) felt that there was a role for an MIS surgeon in fulfilling training obligations. CONCLUSION: The basic and advanced MIS experience of residents in the Caribbean is limited. Surgeon training and resource limitations are major contributing factors. There is a strong desire on the part of surgeons and residents alike for the incorporation of more effective MIS training into the residency programme in the Caribbean.

ANTECEDENTES: Ha habido debates en torno a la factibilidad de incorporar la cirugía mínimamente invasiva (CMI) a la práctica quirúrgica de los países en desarrollo, debido a las limitaciones de recursos y entrenamiento. Este estudio establece cual es el estado actual y el estado deseado en relación con la CMI en los programas de residencia quirúrgica en el Caribe. MÉTODOS: Una versión adaptada de un cuestionario previamente aplicado fue administrada a cirujanos y residentes participantes en el programa de residencia de cirugía general del Hospital Universitario de West Indies en Barbados, Jamaica, y Trinidad y Tobago. Los datos se analizaron usando el Programa estadístico SPSS para ciencias sociales, versión 17.0. RESULTADOS: El cuestionario fue enviado a 41 cirujanos y 41 residentes, y se obtuvo una tasa de respuesta del 65%. La mayor parte de los residentes habían realizado menos de 25 procedimientos laparoscópicos básicos. Hasta un 82% de los residentes, nsentían que no serían capaces de realizar procedimientos laparoscópicos avanzados, debido a la falta de entrenamiento. Los principales factores negativos que afectaban el entrenamiento de la CMI incluían la falta de un horario para usar el salón de operaciones, la falta de equipos, y la falta de preceptores expertos. Tanto los cirujanos (83.4%) como los residentes (93.4%) sentían fuertemente que un laboratorio de habilidades quirúrgicas sería útil para el desarrollo de las habilidades de la CMI. Tanto los cirujanos (85.7%) como los residentes (100%) sentían que el papel de un cirujano debía incluir la obligación de impartir entrenamientos. CONCLUSIÓN: La experiencia básica así como la experiencia avanzada de CMI de los residentes del Caribe es limitada. Las limitaciones en relación con los recursos y el entrenamiento a impartir por los cirujanos, es uno de los factores principales en tal sentido. Por parte de los cirujanos así como de los residentes, existe un fuerte deseo de incorporar entrenamientos más efectivos de CMI al programa de residencia del Caribe.

Association between glycaemic control and quality of life in diabetes mellitus.

BACKGROUND: Relationship between quality of life (QOL) and haemoglobin A1c (HbA1c) amongst diabetics in the community setting is unclear. AIMS: Assess the association between QOL and change in HbA1c in diabetic patients over one year. SETTINGS AND DESIGN: Cohort study of patients from four community clinics in California, USA. METHODS: Diabetic patients identified from databases using International Classification of Disease (ICD-9) codes were asked to complete Short Form 36 (SF-36), which measures health-related QOL, and invited to attend monthly diabetes workshops. From December 2000 to December 2001, data were collected on multiple parameters, including HbA1c. SF-36 surveys were re-collected at project termination. STATISTICAL ANALYSIS: Regression analysis was used to correlate change in HbA1c with change in QOL physical component summary (PCS) and mental component summary (MCS) scores, while considering potential confounders. RESULTS: Of 1679 eligible patients, 380 completed SF-36 at project initiation. 243 of those completed SF-36 at project termination. Pre and post HbA1c data were available for 170 of the 243 who completed SF-36 at both times. Average MCS increased by 8.46% and PCS decreased by 2.24%. After adjustment, a 5% decrease in HbA1c values was associated with a 1% increase in MCS. No association between changes in HbA1c and PCS was observed. CONCLUSIONS: Association between better HbA1c and improved mental, but not physical, QOL may reflect physical inconvenience of increased regimen complexity and mental empowerment from proactive disease management. Larger cohort studies with longer follow-up are needed to further elucidate the relationship between glycemic control and QOL.

An audit of upper gastrointestinal bleeding at Seremban Hospital

We retrospectively analyzed all patients presenting with upper gastrointestinal bleeding to Seremban Hospital over a one-year period. A quarter of the oesophagogastro-duodenoscopies (OGD) performed were performed as emergency for upper gastrointestinal tract bleeding. Gastric ulcers and duodenal ulcers were the two most common findings. Our results suggest that there is a male preponderance of 2:1, the Chinese were more likely to be affected and the elderly (> 60 years) were at highest risk.
