Infantile haemangioendothelioma of the parotid gland: Case report and review of literature.

Haemangioendotheliomas (HAE), although rare but are the most common parotid gland tumours in children. We report a 4-month-old girl who presented with a progressively enlarging right sided facial swelling overlying the angle of the mandible. An Ultrasound of the lesion and a computed tomography (CT) scan of the head and neck was carried out which revealed a large lesion within the right parotid gland. CT scan further demonstrated a direct communication with the right external carotid artery and external jugular vein. Considering the clinical course and radiological findings, there was sufficient evidence to avoid any invasive testing. Due to the self-limiting nature of the disease, patient was managed expectantly.

Surgical-site infections in emergency abdominal paediatric surgeries at a tertiary-care hospital in Pakistan.

A retrospective chart review was carried out in children (neonates to 18 years) who underwent acute surgical abdominal exploration during 2012-2016 at the Aga Khan University Hospital, Karachi, to evaluate the postoperative surgical site infection rates in emergency paediatric abdominal surgery. Incidence of surgical site infection (SSI) was estimated. P-value was calculated, chisquare and non-parametric tests were performed by comparing pre-surgical and post-surgical procedure pathogen occurrence and pre-procedure wound status. Pathogen occurrence related to time-trend of 98 paediatric patients who underwent emergency abdominal surgery was plotted. Of the 94 who were discharged in stable condition, it was found that there was no significant difference between pre- and postsurgical pathogens. Escherichia coli (n=10) was found to be the most common pathogen. Contaminated wounds were associated with higher SSI (p=0.036, OR 1.95 95% CI 0.7-5.4). The study found that pre-surgery wound status could be an indicator for risk of SSI in a post-operative scenario.

Sensitivity and specificity of CT scan in small bowel obstruction among children.

OBJECTIVE: To determine the sensitivity and specificity of computed tomography scan for diagnosing small bowel obstruction among children. METHODS: The retrospective diagnostic test accuracy study was carried out at the Aga Khan University Hospital, Karachi, and comprised data of all patients aged 2-16 years who presented with clinical features of small bowel obstruction and underwent computed tomography scan of abdomen from January 2001 to December 2015Data was analyzed using SPSS19. RESULTS: Of the 98 subjects, 65(66.0%) were males and 33(34.0%) were females. Overall mean age of the patients was 7.67±4.33 years and mean duration of symptoms was 2.84±1.17 days. Sensitivity, specificity, positive and negative predictive values as well as accuracy of computed tomography scan was 97.4%, 81.8%, 94.9%, 90.0% and 93.9% respectively. CONCLUSIONS: CT scan was found to have a high sensitivity, fairly good specificity and accuracy in revealing small bowel obstruction. However, the scan is known to have its limitations in sub-acute intestinal obstruction and primary peritonitis.

Feedback in a clinical setting: A way forward to enhance student's learning through constructive feedback.

Feedback is considered as a dynamic process in which information about the observed performance is used to promote the desirable behaviour and correct the negative ones. The importance of feedback is widely acknowledged, but still there seems to be inconsistency in the amount, type and timing of feedback received from the clinical faculty. No significant effort has been put forward from the educator end to empower the learners with the skills of receiving and using the feedback effectively. Some institutions conduct faculty development workshops and courses to facilitate the clinicians on how best to deliver constructive feedback to the learners. Despite of all these struggles learners are not fully satisfied with the quality of feedback received from their busy clinicians. The aim of this paper is to highlight what actually feedback is, type and structure of feedback, the essential components of a constructive feedback, benefits of providing feedback, barriers affecting the provision of timely feedback and different models used for providing feedback. The ultimate purpose of this paper is to provide sufficient information to the clinical directors that there is a need to establish a robust system for giving feedback to learners and to inform all the clinical educators with the skills required to provide constructive feedback to their learners. For the literature review, we had used the key words glossary as: Feedback, constructive feedback, barriers to feedback, principles of constructive feedback, Models of feedback, reflection, self-assessment and clinical practice etc. The data bases for the search include: Cardiff University library catalogue, Pub Med, Google Scholar, Web of Knowledge and Science direct.

Determination of Normal Anal Position Using the Anal Position Index in Pakistani Neonates.

INTRODUCTION: Anterior displacement of the anus (ADA) is recognized as a common congenital abnormality of the anorectal region and is often associated with constipation. It is diagnosed through a physical examination by measuring the Anal Position Index (API) at birth. METHODS: A cross-sectional study was conducted utilizing non-probability consecutive sampling of all patients presenting with ADA at our institute over a six-month period. The study focused on key variables, including the measurement of scroto-anal and scroto-coccygeal distances in boys and fourchette-anal and fourchette-coccygeal distances in girls. Data collection was carried out using a structured proforma, ensuring prospective data collection from neonates meeting the selection criteria (neonates born at our center and identified by the neonatology team as having a normal anal opening, regardless of their gestational period or birthweight). RESULTS: Our study comprised a cohort of 204 neonates. The Anal Position Index was determined to be 0.36 ± 0.07 for male newborns and 0.24 ± 0.06 for female newborns. Notably, a statistically significant correlation was observed between the API and factors such as gestational age, birth weight, and advancing paternal age. CONCLUSION: The assessment of the API proves highly valuable in identifying indicators of ADA in neonates, facilitating early disease detection, and guiding the prompt management of subsequent functional symptoms, such as constipation, during later stages of life.

Unintentional Injuries In Children: Are Our Homes Safe?

Unintentional injuries are a leading cause of death in childhood globally. Injuries lead to emotional trauma and financial burden for children, parents, and society. Here are the frequencies of unintentional injuries in children presented to the emergency and paediatric surgery clinics of the Aga Khan University Hospital, Karachi, Pakistan, from January to December 2012. Aretrospective chart review of children aged 0 day to 14 years presented with falls, burns, foreign body ingestion or inhalation, poisoning, fingers caught in doors, electrocution injuries and drowning, was conducted. Atotal of 165 children were included. Domestic injuries were frequently occurring injuries in our set-up which could be prevented by doing small adjustments to make the home safe for children.

Functional Outcome of Anorectal Malformations and Associated Anomalies in Era of Krickenbeck Classification.

OBJECTIVE: To describe the management and functional outcome of anorectal malformations and associated anomalies according to Krickenbeck classification. STUDY DESIGN: Case series. PLACE AND DURATION OF STUDY: The Aga Khan University Hospital, Karachi, from January 2002 to December 2012. METHODOLOGY: Anorectal anomalies were classified according to Krickenbeck classification. Data was collected and proforma used regarding the primary disease associated anomalies, its management and functional outcome, according to Krickenbeck classification. Cases included were: all those children with imperforate anus managed during the study period. Qualitative variables like gender and functional outcome were reported as frequencies and percentages. Quantitative variables like age were reported as medians with interquartile ranges. RESULTS: There were 84 children in study group. Most common associated anomaly was cardiac (38%), followed by urological anomaly (33%). All children were treated by Posterior Sagittal Anorectoplasty (PSARP). Fistula was present in 64 out of 84 (76%) cases. The most common fistula was rectourethral (33%), followed by recto vestibular (31%). According to Krickenbeck classification, continence was achieved in 62% children; however 27% children were constipated, followed by 12% children having fecal soiling. CONCLUSION: Functional outcome of anorectal malformation depends upon severity of disease. A thorough evaluation of all infants with ARM should be done with particular focus on cardiovascular (38%) and genitourinary abnormalities (33%).
