Magnet ingestion has recently increased among children. Multiple magnets can lead to serious adverse events owing to pressure necrosis of trapped bowel wall; therefore, urgent removal of the magnet is recommended. However, awareness of magnet ingestion and adverse events associated with it are lacking among the general population and some healthcare professionals. Herein, we demonstrate the adverse events associated with prolonged retention of ingested magnets and endoscopic management of ingested magnets in children.

We present a case series of 3 patients with magnet ingestion. Foreign body ingestion was confirmed on fluoroscopy. After fluoroscopy, all children underwent EGD under propofol sedation in a left lateral position. A Roth net was used to remove magnets.

Three patients (median age 5 years), each with ingestion of 2 magnets of different shapes and sizes and with variable periods of ingestion, underwent EGD. In 2 patients, both magnets were Successfully removed. In 1 patient, 1 magnet could not be removed because it became dislodged deep in the jejunum. All 3 patients had developed magnet-related fistula (gastroduodenal 1 patient; duodenojejunal 2 patients). Patients with duodenojejunal fistula were managed conservatively. There was mild self-limited bleeding during magnet removal in 1 patient. There were no major adverse events related to endoscopic removal.

Endoscopic removal of magnets is feasible and safe in children. Few patients with fistulas can be managed conservatively. There is an unmet need to increase societal awareness of magnet ingestions and adverse events associated with it.

Methodology This was a (retrospective) case-control study carried out between December 1, 2021, and March 30, 2022, at the Basheeran Umar Eye Hospital in Islamabad, Pakistan, and Sheikh Khalifa bin Zayed Al Nayhan Combined Military Hospital in Rawalakot in Kashmir, Pakistan. A total of 200 participants between the ages of five and 16 years (106 cases with REs and 94 controls without REs) were included in this study. After obtaining informed consent from the parent accompanying the participant, the parent was further interviewed to extract information regarding biodata, breastfeeding, and other parameters including parental myopia, the number of hours spent on outdoor activities, on gadgets, and doing near work; this data was entered into a questionnaire. The participant's visual acuity was then checked using the Snellen chart. Data were analyzed using SPSS Statis work. Conclusion This study demonstrates that breastfeeding plays a protective role in the prevention of REs. The type of breastfeeding also had a significant effect on the development of REs, i.e., children exclusively breastfed (regardless of the duration of breastfeeding) were less likely to develop errors of refraction in the future.Fixed drug eruptions (FDEs) are dermatological manifestations of drug reactions that often occur in the same location upon re-exposure to a drug. They usually appear as erythematous-violaceous, circular patches, but several different variants have been described. They can often present without any associated symptoms, but in some cases, patients may complain of pain and pruritus. The lesions are often underdiagnosed or mistaken for insect bites, urticaria, or erythema multiforme; thus, an effort to bring awareness to this condition is warranted. We present a 33-year-old African-American female who presented to the urgent care presenting with several violaceous patches of varying sizes that started two days ago. The lesions were located on the left shoulder, abdomen, right flank region, and behind the right knee. The lesions were associated with mild pain and pruritus. She believed she was bit by insects but denied seeing any insects at home or participating in any recent outdoor activities. She stated that shresolution of symptoms. It also represents the essential questions to ask when suspecting FDE.Background Challenging perineal defects resulting from extralevator (ELAPE) and standard abdominoperineal excision (APE) have given rise to an emerging multidisciplinary approach between colorectal and plastic surgeons. At present, there is a relative paucity of evidence on best practice. This study sought to assess current national practice concerning perineal reconstruction following APE/ELAPE in the United Kingdom (UK) and to determine the factors involved in reconstruction choice. Methodology An anonymised survey was circulated to consultant plastic surgeons at all 48 UK centres performing perineal reconstruction following APE/ELAPE. Responses were collected between October 2021 and April 2022. Results Complete responses were received from 24 units nationally. All units had a dedicated APE/ELAPE service. Overall, 70% adopted a standardised reconstructive approach, the most common being the inferior gluteal artery perforator flap (n = 11). Significant variation was identified in the reconstructive technique. Similar differences were observed in the perceived importance of surgical factors guiding the reconstructive decision-making process, the top priorities being the size of the defect and previous radiotherapy. Conclusions The variability of responses suggests a lack of national consensus on optimal reconstruction following APE/ELAPE, despite the majority of centres employing a standardised approach to reconstruction. Our study highlights important surgical decision-making factors and provides valuable insight to aid in developing national collaborative evidence-based guidelines on best practice.Gangrenous cholecystitis is a potentially fatal complication of acute cholecystitis that presents with right upper quadrant pain and sepsis. Due to the overlap in clinical features with ascending cholangitis, gangrenous cholecystitis can be easily misdiagnosed, resulting in treatment delay. While the gold standard of diagnosis of gangrenous cholecystitis is direct visualization during surgery and tissue sampling to pathology, some imaging features can guide the diagnosis to appropriate early surgical treatment of gangrenous cholecystitis. A 78-year-old female presented to the emergency department with right upper quadrant pain, sepsis, and altered mental status. Imaging findings on ultrasound and CT were suggestive of gangrenous cholecystitis. However, clinically the patient presented with ascending cholangitis symptoms. Instead of an emergent cholecystectomy, percutaneous cholecystostomy (PTC) was performed. After the PTC, the patient worsened clinically and despite surgical intervention, the patient expired due to septic shock and multiple organ failure.The adaptive significance of colorful or exaggerated traits (i.e., ornaments) expressed in females is often unclear. Competing hypotheses suggest that expression of female ornaments arises from maladaptive (or neutral) genetic inheritance from males along with incomplete epigenetic regulation, or from positive selection for ornaments in females under social competition. Whether costly or advantageous, the visibility of such traits can sometimes be behaviorally modulated in order to maximize fitness. Female eastern fence lizards express blue badges that are variable in size and color saturation. These are rudimentary compared to those seen in males and carry important costs such as reduced mating opportunities. Body temperature is a well-established enhancer of badge color, and thus thermoregulation may be one way these animals modulate badge visibility. We quantified realized body temperatures of female lizards paired in laboratory trials and observed that females with larger badges attained higher body temperatures when freely allowed to thermoregulate, sometimes beyond physiological optima. In this association between phenotype and behavior, females with larger badges exhibited thermoregulatory patterns that increase their badges' visibility. This signal-enhancing behavior is difficult to reconcile with the widely held view that female ornaments are maladaptive, suggesting they may carry context-dependent social benefits.Snakes are a phylogenetically diverse (> 3500 species) clade of gape-limited predators that consume diverse prey and have considerable ontogenetic and interspecific variation in size, but empirical data on maximal gape are very limited. To test how overall size predicts gape, we quantified the scaling relationships between maximal gape, overall size, and several cranial dimensions for a wide range of sizes (mass 8-64,100 g) for two large, invasive snake species Burmese pythons (Python molorus bivittatus) and brown treesnakes (Boiga irregularis). Although skull size scaled with negative allometry relative to overall size, isometry and positive allometry commonly occurred for other measurements. For similar snout-vent lengths (SVL), the maximal gape areas of Burmese pythons were approximately 4-6 times greater than those of brown treesnakes, mainly as a result of having a significantly larger relative contribution to gape by the intermandibular soft tissues (43% vs. 17%). In both snake species and for all types of prey, the scaling relationships predicted that relative prey mass (RPM) at maximal gape decreased precipitously with increased overall snake size. For a given SVL or mass, the predicted maximal values of RPM of the Burmese pythons exceeded those of brown treesnakes for all prey types, and predicted values of RPM were usually least for chickens, greatest for limbed reptiles and intermediate for mammals. The pythons we studied are noteworthy for having large overall size and gape that is large even after correcting for overall size, both of which could facilitate some large individuals (SVL = 5 m) exploiting very large vertebrate prey (e.g., deer > 50 kg). Although brown treesnakes had longer quadrate bones, Burmese pythons had larger absolute and larger relative gape as a combined result of larger overall size, larger relative head size, and most importantly, greater stretch of the soft tissues.
