Introduction Gastrografin (GGF) is a radiopaque contrast medium commonly used for diagnostic examination of the gastrointestinal (GI) tract. Available evidence suggests it has therapeutic and predictive value in the management of adhesional small bowel obstruction (ASBO). Thus, we investigated the use of GGF amongst patients who had a small bowel obstruction and audited the practice in University Hospital, Ayr. Methods Initial retrospective data of patients who had gastrografin for small bowel obstruction were extracted from April 2015 to August 2019 and analysed. After our local presentation and on implementing a GGF protocol, we prospectively collected data from February to June 2020 to close our audit. Results GGF showed a comparable therapeutic effect on ASBO in both audit cycles (72.2%-66.7%). Approximately 50% of unresolved cases were operated within 24 hours of GGF administration in both cycles. GGF consistently demonstrated a therapeutic benefit in refractory faecal impaction (100% in both cycles) and postoperative ileus (≥ 80%). Early use of computed tomography (CT) (less than 24 hrs) did not confer any added advantage (82.5% v 61.5%), however, it helped in making an appropriate diagnosis and the subsequent early gastrografin usage (78.3% v 92.3%) in ASBO. Conclusion GGF serves a very good therapeutic purpose in resolving ASBO, refractory constipation, and in rare non-resolving cases of postoperative ileus. Early CT diagnosis of ASBO is advocated before the administration of gastrografin. Unsuccessful resolution after 24 hrs of GGF is an indication for operative intervention.
Aromatase inhibitors (AIs), such as anastrozole, letrozole, and exemestane, are commonly used as adjuvant endocrine therapy in hormone-receptive breast cancer in postmenopausal women. Their adverse effects are well documented, except for visual disturbances. The purpose of this study was to review the current literature on ocular disease linked to AI use. Due to the scarcity of published data, any suggested ophthalmic adverse events were included to increase awareness of these drugs. The ocular side effects of tamoxifen use are well documented and were not included. Cases of rare side effects such as papilloedema, macular oedema, and uveitis associated with anastrozole and letrozole have been reported. Studies demonstrating retinopathy, in the form of crystalline retinopathy, hemicentral retinal artery occlusion, and retinal haemorrhages, are also noted. All three third-generation AIs can also lead to ocular surface diseases such as corneal epithelial changes, blepharitis, and keratitis. There is slightly more literature available regarding anastrozole-related ocular diseases. Although these are likely rare side effects, we recommend a high level of clinical suspicion when assessing patients with visual symptoms and on AIs. Larger prospective studies are necessary to further investigate these complications.
Cobb's tufts, also known as iris vascular tufts (IVT) and iris microhemangiomas (IMH), are coils of tightly clustered, minute blood vessels at the iris pupillary border. This study aimed to analyze previous literature and provide an update on Cobb's tufts. A systematic literature review was carried out by interrogating PubMed, Google Scholar, Cochrane, and Embase databases. Full-text English language articles of any year were included in this study. A total of 38 articles fulfilled our inclusion criteria. A total of 115 reported cases of Cobb's tufts were incorporated into our review. The age of the patients ranged between 36 and 86 years. No sex or racial predisposition was noted. Most patients had no history of trauma, surgery, or blood dyscrasia. The majority of cases are asymptomatic and bilateral unless a spontaneous hyphema occurs, which most commonly presents as blurred vision. The etiology of this condition remains uncertain; however, a higher incidence has been shown in systemic conditions such as myotonic dystrophy and diabetes. Fluorescein angiography can be utilized to investigate tufts. Management includes treatment of raised intraocular pressure, observation for single bleeds, laser therapy for recurrent hyphemas, and lastly, iridectomy, which is considered in cases of recurrence following laser treatment.
An 83-year-old man presented to the emergency department (ED) during the peak of the first wave of the SARS CoV-2 (COVID-19) pandemic with severe abdominal pain, mimicking a severe abdominal pathology. He was found to have features suggestive of COVID-19 infection radiologically, with no leaking aortic aneurysm, bowel ischemia, pancreatitis, or perforation. With worsening symptoms, a repeat computer tomography (CT) scan four days later showed features of bowel ischemia, and he underwent a laparotomy and right hemicolectomy. Four real-time reverse transcription-polymerase chain reaction (rRT-PCR) tests were negative. He was still considered to be infected with COVID-19 and died from complications arising from multi-organ failure. This case highlights an atypical presentation of a possible COVID-19 infection, the urgency to have additional diagnostic tests apart from rRT-PCR, and the necessity to use the appropriate personal protective equipment (PPE) during the pandemic.
Intestinal malrotation presents as an emergency in the neonate and within the first year of life. Incomplete intestinal rotation may remain asymptomatic and undiagnosed. Adult patients are usually diagnosed incidentally while being investigated for nonspecific abdominal symptoms. We report a case of a 43-year-old female who presented with a 10-day history of paraumbilical abdominal pain. Computed tomography demonstrated features of incomplete intestinal rotation and a centrally located inflammatory mass related to the appendix. She underwent a laparotomy and appendectomy. Upon a brief literature review of similar cases, there seems to be a conflict of views regarding the management of incidentally diagnosed adult incomplete intestinal rotation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
