The dorsal metacarpal artery (DMCA) flap is a versatile option in the armamentarium of the reconstructive hand surgeon, especially for resurfacing dorsal finger defects where the flap options are limited. The flap fulfills most of the reconstructive principles such as "to replace like with like" and is simple, reliable, and easy to harvest with minimal donor site morbidity. In this report, we discuss the case of a 37-year-old male patient who presented with a partially healed wound over the right middle finger. Several variations of the DMCA flap have been described in the literature, and these are briefly described here along with their applications and vascular basis.Vitiligo is a cutaneous condition that causes loss of pigmentation; it can be associated with other autoimmune conditions. Sjogren's syndrome is a chronic inflammatory autoimmune condition that classically presents with xerophthalmia and xerostomia. Rarely, vitiligo has occurred in individuals with Sjogren's syndrome. Ro 20-1724 A 51-year-old Hispanic woman presented with vitiligo. Her laboratory investigation was consistent with Sjogren's syndrome; she subsequentially developed xerophthalmia and arthritis. The association between vitiligo and other autoimmune conditions is reviewed and the association of vitiligo and Sjogren's syndrome is discussed.Introduction Ileostomies are life-saving procedures used for temporary fecal diversion in complicated cases of ileal perforation. However, an ileostomy is associated with several complications. The goal of this study was to determine the frequency and complications of ileostomy in the Jinnah Postgraduate Medical Centre, Karachi, Pakistan. Methodology We conducted a longitudinal observational study from July 2019 to July 2020. All patients older than age 12 receiving an ileostomy were included. Patient examinations were conducted on the first postoperative day and were assessed for hemorrhage and necrosis. Examinations were conducted on the seventh postoperative day to assess stoma retraction, stenosis, prolapse, and high-output fistula. Patients were monitored via follow-up in the outpatient clinic every 15 days to record any complications for three months until the reversal was performed. All data were analyzed using IBM SPSS Statistics for Windows, Version 25.0. (Armonk, NY IBM Corp.). Result A total of 84 the morbidity of the patients.Cerebral venous sinus thrombosis is a rare and serious complication of nephrotic syndrome. A case of a five-year-old boy with nephrotic syndrome is described here. On the fourth day of admission, the child developed an occasional cough. A percutaneous renal biopsy was conducted to characterize the frequent-relapse nephrotic syndrome that was developed. After suspension of oral anticoagulants, the patient developed mild dizziness, headache, and vomiting. The child was diagnosed with intracranial venous sinus thrombosis based on data obtained using head computed tomography and magnetic resonance imaging. He recovered after receiving heparin and warfarin anticoagulants. We summarized the case and reviewed the literature here, showing that early diagnosis and treatment have a significant impact on the prognosis of this complication.The COVID-19 viral infection, caused by the novel coronavirus severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), is a currently ongoing global pandemic that, as of mid-October, 2020, has resulted in more than 38.7 million confirmed cases globally and has caused more than 1.1 million fatalities. COVID-19 infection is associated with severe life threatening respiratory and cardiac complications such as acute respiratory distress syndrome (ARDS), pneumonia, shock, cardiac arrhythmias, myocardial infarction and heart failure, particularly in the acute infectious stage. Acute myopericarditis is another reported cardiac complication of COVID-19. Case reports have been limited in reporting the effects of COVID-19 in the post-symptomatic period. In this article, we present a case of acute myopericarditis resulting 6 to 8 weeks after testing positive for COVID-19. Here we will breakdown the initial emergency department (ED) presentation, with particular attention to the electrocardiogram (ECG) findings of acute myopericarditis. This case, to the our best knowledge and after an extensive literature review, depicts the first case of myopericarditis in the post COVID-19 infection recovery phase.In recent years, the role of immune checkpoint inhibitors (ICI) in cancer treatment has rapidly expanded. In randomized clinical trials, these agents have demonstrated clinical efficacy in extending survival and increasing response rates. Immune-related adverse effects (irAEs) involving various organs have been frequently narrated. Herein, we present a case report of thrombotic thrombocytopenic purpura (TTP) as a rare side effect of nivolumab, plus ipilimumab, in the treatment of metastatic renal cell carcinoma (RCC). A review of the literature for other case reports of TTP during treatment with ICIs was also performed. Our aim is to elucidate the significance of early recognition of this rare adverse effect in patients being treated with this relatively newer class of medications.Introduction Sexually transmitted infections are commonly tested for in the emergency department (ED), but diagnostic test results are often unavailable during the clinical encounter. Methods We retrospectively reviewed health records of 3,132 men ≥18 years that had an emergency department visit in northeast Ohio between April 18, 2014 and March 7, 2017. All subjects underwent testing for Neisseria gonorrhoeae and Chlamydia trachomatis. Independent t-tests and chi-square analyses were performed as well as multivariable regression analysis. Results On univariable analysis, men with N gonorrhoeae and/or C trachomatis, compared with uninfected men, were younger (25.9 vs 32.4 years), more likely to be of Black race (91.7% vs 85.6%), less likely to be married (3.7% vs 10.2%), less likely to arrive to the ED by ambulance or police (1.7% vs 4.1%), and more likely to be diagnosed with a urinary tract infection (8.3% vs 3.7%), to be treated for gonorrhea and chlamydia in the ED (84.6% vs 54.9%), and to have higher emergency severity index (ESI) scores (3.8 vs 3.6) (P ≤ .03 for all). On urinalysis, men infected with N gonorrhoeae and/or C trachomatis had significantly more white blood cells (55.1 vs 20.9); more mucus (1.3 vs 1.2); higher leukocyte esterase (1.5 vs .4); fewer squamous epithelial cells (.6 vs 1.4); higher urobilinogen (1.1 vs .8); higher bilirubin (.09 vs .05); and more protein (.4 vs .3) (P ≤ .04). Conclusions Demographic and urinalysis findings can be associated with an increased odds of men being infected with N gonorrhoeae and/or C trachomatis.Syphilis is a bacterial infection caused by Treponema pallidum. It spreads usually via sexual contact. Syphilis generally presents as a multisystem disease, with symptoms resembling and often confused with those of other diseases, thus often called "the great mimicker". Neurosyphilis is a rare but late course of the disease process when the meninges and central nervous system (CNS) are involved. Otosyphilis is an even rarer, yet important complication of neurosyphilis and a rare cause of sensorineural deafness often misdiagnosed. We present the case of a 46-year-old Caucasian male admitted for acute onset bilateral hearing loss caused by otosyphilis. We include a discussion about cerebrospinal fluid (CSF) protein analysis in individuals diagnosed with neurosyphilis.Wunderlich syndrome is a rare clinical syndrome characterized by the sudden onset of spontaneous, nontraumatic hemorrhage into renal subcapsular and retroperitoneal region. We present the case of a 24-year-old hypertensive who presented with acute flank pain and was found to have perinephric hematoma. He was managed conservatively and the follow-up revealed complete resolution of the hematoma with no structural abnormality of kidney. His connective tissue disorder/vasculitis work up was also normal.Bipolar disorder (BD) is known for impairments in neurotrophic and neuroprotective processes, which translate into emotional and cognitive deficits affecting various brain regions. Using its neuroplastic properties, lithium, thus far, is the mood stabilizer used to amend the pathophysiological imbalance in BD. Neuroplasticity has gained massive popularity in the research department in the past decade, yet it lacks direct effort in changing the protocol through which physicians treat BD. Physical activity alongside cognitive therapy is theorized to produce long-term changes in the executive control network due to the assimilation of new neurons, amendment of emotional lability through hippocampal neurogenesis, and strengthening the stability of frontosubcortical and prefrontolimbic brain regions via neurogenesis. This review aims to provide an incentive for utilizing neuroplastic mechanisms concerning impairments dispensed by BD.This study examined the association between naturalistically-observed in-person contact with one's ex-partner and separation-related psychological distress (SRPD). 122 recently-separated adults were assessed using the Electronically Activated Recorder (Mehl, 2017) on three occasions across five months. The association between in-person contact with one's ex-partner, as a between-person variable, and concurrent SRPD was not reliably different from zero, nor was the time-varying effect of in-person contact. However, more frequent in-person contact with one's ex-partner predicted higher SRPD two months later, above and beyond the variance accounted for by concurrent in-person contact, demographic, relationship, and attachment factors. Follow-up analyses yielded that this effect was only present for people without children; a one standard deviation increase in in-person contact offset and slowed the predicted decline in SRPD over two months by 112%. Our discussion emphasizes new ways to think about the role of in-person contact in shaping adults' psychological adjustment to separation over time.Image segmentation is critical to lots of medical applications. While deep learning (DL) methods continue to improve performance for many medical image segmentation tasks, data annotation is a big bottleneck to DL-based segmentation because (1) DL models tend to need a large amount of labeled data to train, and (2) it is highly time-consuming and label-intensive to voxel-wise label 3D medical images. Significantly reducing annotation effort while attaining good performance of DL segmentation models remains a major challenge. In our preliminary experiments, we observe that, using partially labeled datasets, there is indeed a large performance gap with respect to using fully annotated training datasets. In this paper, we propose a new DL framework for reducing annotation effort and bridging the gap between full annotation and sparse annotation in 3D medical image segmentation. We achieve this by (i) selecting representative slices in 3D images that minimize data redundancy and save annotation effort, and (ii) self-training with pseudo-labels automatically generated from the base-models trained using the selected annotated slices. Extensive experiments using two public datasets (the HVSMR 2016 Challenge dataset and mouse piriform cortex dataset) show that our framework yields competitive segmentation results comparing with state-of-the-art DL methods using less than ~ 20% of annotated data.
