Diagnostic accuracy of axillary nodal ultrasound after neoadjuvant chemotherapy in node-positive breast cancer patients: A validation study.

OBJECTIVE: To determine the accuracy and false negative rate of axillary ultrasound compared to sentinel node biopsy. METHODS: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, from February 1 to March 31, 2021, and comprised data of breast cancer patients who had undergone neo-adjuvant chemotherapy followed by axillary lymph node dissection or axillary disease diagnosed using lymph node biopsy or sentinel lymph node biopsy between January 1, 2016, and December 30, 2020. After receiving neoadjuvant chemotherapy, axillary ultrasound findings were compared with histopathology of lymph nodes. Data was analysed using SPSS 22. RESULTS: Of the 155 patients evaluated, 104(67.1%) were diagnosed with negative axillary lymph nodes and 51(32.9%) were diagnosed with positive axillary lymph nodes post-chemotherapy. The overall mean age was 51.13±1.3 years. When histopathology results were compared with those of axillary ultrasound, 36(23.2%) cases turned out to be true positive, while 23(14,8%) were false negative, yielding a positive predictive value of 75% and negative predictive value of 65%. Axillary ultrasound had 75% accuracy, false negative rate 30%, sensitivity 61% and specificity 84.4%. CONCLUSIONS: Axillary ultrasound was found to be fairly useful, but not completely reliable, in identifying positive lymph nodes.

Mesenteric ischemia in COVID-19 patients: A review of current literature.

BACKGROUND: Coronavirus disease 2019 (COVID-19) virus has affected all the systems of the body, defying all impressions of it being a respiratory virus only. AIM: To see the association of mesenteric ischemia with COVID-19. METHODS: After initial screening and filtering of the titles on PubMed and Google Scholar, 124 articles were selected. Articles were read in full, and the references were skimmed for relevance. Twenty-six articles (case reports and case series) were found to eligible for inclusion. References of these 26 articles were checked for any additional cases. Two more publications were found, and a total of 28 articles (22 case reports and 6 case series) have been included for review in this manuscript. RESULTS: A total of 41 cases of acute mesenteric ischemia in COVID-19 patients have been reported in the literature since the outbreak of this pandemic. Most of them include patients with comorbidities. CONCLUSION: In conclusion, based on this literature review and precise published knowledge regarding acute mesenteric ischemia in patients with COVID-19, it is essential to understand its relevance in all patients with gastrointestinal symptoms. The threshold for the diagnostic investigations should also be kept low for the timely diagnosis and management of this disorder.

Signet ring cell cancer of Ampulla of Vater-first ever case reported in a teenager and a review of literature.

Ampullary cancers are rare accounting for 0.2% of all gastrointestinal cancers. Signet ring is a rare variant of adenocarcinoma, characterized by having more than 50% of mucin secreting cells and clinically having a worse prognosis. We present the case of a teenage girl with this tumor, the youngest ever reported in medical literature. An 18 years old girl with no significant past medical history presented to our clinic with symptoms of upper abdominal pain and jaundice. Her upper GI endoscopy showed an ampullary lesion which was biopsied-diagnosing it as adenocarcinoma. She underwent a pancreato-duodenectomy (Whipple's procedure) with Child's reconstruction and a feeding jejunostomy. Her final histopathology report was documented as infiltrating adenocarcinoma of Signet Ring variety arising from the Ampulla of Vater. Being such a rare entity, there is a lack of randomized trials advising the optimum treatment for such cases. Till then anecdotal experiences will drive the optimum management of this rare disease.

Topical Diltiazem Ointment For Post- Hemorrhoidectomy Pain.

BACKGROUND: Hemorrhoids are one of the most common anal pathology affecting millions of people around the world. Milligan-Morgan open hemorrhoidectomy is the most effective hemorrhoidectomy method used as gold standard procedure. Post-operative pain is recognized as a distressing complication of hemorrhoidectomy leading to increase hospital stay and psychological stress to both patient and surgeon. This study is designed to determine the efficacy of diltiazem gel in relieving pain after hemorrhoidectomy caused by anal muscle spasm. This will lead to decreased hospital stay and save both patient and surgeon from stress in postoperative period. OBJECTIVE: To compare mean post-operative pain in patients undergoing hemorrhoidectomy with vs. without topical application of diltiazem gel. METHODS: Total 80 patients who were diagnosed with third- and fourth-degree hemorrhoids and undergo hemorrhoidectomy were included in the study. Patients were randomly allocated to two groups using opaque sealed envelope method. Group A and B both have 40 patients in each group. Pain score was measured on visual analogue scale (VAS) by asking the patients to fill a questionnaire or by the help of the doctor. RESULTS: The patient's average age was 39.98±7.98 years. At 24 hours, mean pain score was significantly high in group B than group A [7.23±0.95 vs. 5.38±1.06; p=0.0005]. At 3rd post-operative day, mean pain score was significantly high in group B than group A [5±0.78 vs. 3.08±0.99; p=0.0005]. Seventy percent cases were observed in group B which required rescue analgesia. CONCLUSIONS: It is concluded that application of diltiazem ointment at perianal area with standard treatment considerably decreases pain after haemorrhoidectomy.

Bilio-thorax: an unrecognized complication of liver surgery.

INTRODUCTION: Although a rare complication, Biliothorax, or chole-thorax as it has been called in literature, is a devastating entity if not recognized early. Various causes have been reported for biliothorax like inflammatory, abdominal trauma, neoplastic, the most frequent being percutaneous hepatic intervention. CASE: We present the case of a 60 year old male, treated for colon cancer, who developed this complication after liver surgery. He was promptly diagnosed, managed conservatively and responded to our treatment. This has been infrequently reported. DISCUSSION: Although a rare complication, Biliothorax, is a fatal complication if missed. The presence of bile in the pleural cavity is damaging and can lead to empyema, entrapped lung and even ARDS. Hence it is imperative to recognize early, find the cause and treat appropriately. CONCLUSION: Biliothorax is an under reported complication of liver surgery which can have disastrous effects on the patient leading to morbidity and even mortality. It is vital to recognize it early and treat accordingly.
