RESUMO
BACKGROUND: Corneal transplants are the most common type of transplant and increasing in frequency. Donor cornea tissues are a rare source of herpes simplex virus (HSV) transmission and not routinely tested for presence of HSV. Donor graft-to-recipient transmission typically causes graft failure and anterior uveitis, and extra-ocular HSV disease has not been previously reported. We present a case of HSV transmission from donor cornea tissue that nearly cost the corneal transplant recipient his life. CASE REPORT: An elderly immunocompetent man developed an acute illness 10 days after having donor corneal tissue implanted in a Descemet membrane endothelial keratoplasty (DMEK). He was found to have HSV necrotizing hepatitis per liver biopsy, trilineage cytopenia, rhabdomyolysis, acute kidney failure, altered mental status, early-stage hemophagocytic lymphohistiocytosis (HLH), and donor corneal tissue implant infection resulting in graft failure and anterior uveitis. HSV DNA was detected in cerebral spinal fluid, peripheral blood, explanted donor corneal tissue, and anterior chamber fluid (220 million HSV DNA copies per mL). HSV-1 seroconversion denoted a primary HSV infection, and the patient had no other risk factor for HSV acquisition. Early recognition of HSV dissemination prompting treatment with intravenous acyclovir, as well as a short course of HLH-directed therapy, resolved the systemic illness. Vision was restored to near normal by replacement of the infected corneal graft with new donor DMEK tissue in conjunction with intravitreal foscarnet treatment. CONCLUSION: Awareness of the potential risk of donor cornea tissue transmitting HSV and leading to life-threatening HSV disease is paramount to early diagnosis and treatment. The role of donor cornea tissue in HSV transmission and disease merits additional attention and investigation.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) can cause multisystem complications, with pulmonary involvement associated with the highest mortality. Pneumothorax (PT) and pneumomediastinum (PM) are uncommon complications of COVID-19 that have been reported to occur in the absence of trauma or mechanical ventilation. This study seeks to determine the incidence of these complications in patients with COVID-19 and evaluate clinical characteristics and outcomes. METHODS: We identified 3375 patients admitted to our health system during March 2020 through November 2020 who tested positive for SARS-CoV-2 with a polymerase chain reaction test. Patients were screened for PT or PM and were matched to COVID-19-positive patients without PT and/or PM. Data compared demographics, clinical characteristics, and laboratory values. RESULTS: Out of a total of 3375 COVID-19 admissions, 33 patients with PT/PM (1%) were compared to 32 matched controls without PT and/or PM. The patients with PT and/or PM demonstrated a significantly higher incidence of concomitant cancer diagnosis than those without PT and/or PM (18% vs 3%, respectively; P = 0.05). Those with PT and/or PM required significantly more invasive mechanical ventilation than those without PT and/or PM (79% vs 47%; P < 0.01). Mortality was significantly higher among those patients with PT and/or PM than those without PT/PM (55% vs 25%; P < 0.05). DISCUSSION: A significant number of COVID-19 patients with PT and/or PM had a concomitant cancer diagnosis, required supplemental oxygen on admission, and invasive mechanical ventilation during hospitalization. Additionally, the COVID patients with PT and/or PM had significantly higher mortality compared to those without PT and/or PM. However, with all retrospective studies, there are limitations.

Strongyloidiasis is a helminth infection affecting 613.9 million people annually, mainly in the tropics and subtropics. The reported seroprevalence in the United States is 4% with most of the cases reported in immigrants. Human T-lympho-tropic virus 1 (HTLV-1) infections, hypogammaglobulinemia, immunosuppressant use - particularly steroid use, alcoholism, and malnutrition have been associated with an increased risk of strongyloidiasis. Recently, cases of strongyloidiasis hyperinfection syndrome have been described in coronavirus disease 2019 (COVID-19) patients treated with steroids as well. This brief review discusses the epidemiology, clinical features, management, and prevention of strongyloidiasis including some facts about the infection in pregnancy, transplant recipients, and COVID-19 patients. We conducted an online search using the PubMed, Scopus, and Google Scholar databases. Strongyloidiasis can be asymptomatic or present with mild symptoms. Strongyloides stercoralis is known to cause autoinfection. In immunocompromised individuals, it can present with severe symptoms, hyperinfection, or disseminated disease. Reported mortality in cases of disseminated Strongyloidiasis is 87.1%. Serology and detection of larvae in stool by direct microscopy are the most commonly used methods to diagnose strongyloidiasis. The drug of choice for the treatment is ivermectin. However, the use of ivermectin in human pregnancy is not well studied, and its teratogenic risks are unknown. Proactive screening of strongyloidiasis is necessary in immunocompromised individuals to prevent severe disease.
RESUMO
INTRODUCTION: Trimethoprim-sulfamethoxazole (TMP-SMX) use in immunocompromised patients can cause dose-dependent electrolyte irregularities including hyponatremia, hyperkalemia, and metabolic acidosis. We report a case of isolated hyponatremia caused by low-dose TMP-SMX use in an immunocompetent patient that mimicked the syndrome of inappropriate antidiuretic hormone secretion (SIADH). CASE PRESENTATION: A 72-year-old woman was admitted to the hospital for acute onset of weakness and ambulatory dysfunction after starting TMP-SMX (160 mg/800 mg). She was found hyponatremic (sodium level, 125 mmol/L, down from 141 mmol/L prior to medication initiation). After ruling out diuretics use, and adrenal and thyroid dysfunction, we started her on intravenous saline infusion to manage her TMP-SMX-induced hyponatremia, and her symptoms resolved. DISCUSSION: Electrolyte problems in immunocompromised patients treated for opportunistic infections with high-dose TMP-SMX (≥ 8 mg/kg/d TMP) are well-documented. However, the effects in immunocompetent patients are uncommon when standard dose (< 8 mg/kg/d TMP) is used. CONCLUSIONS: TMP-SMX blocks the aldosterone-mediated sodium reabsorption in the collecting ducts, and the trimethoprim component itself is structurally similar to potassium-sparing diuretics, which block sodium uptake at the distal nephron-both of which can cause hyponatremia.

An immunocompetent man in his 20s came to the hospital for shortness of breath, fevers and lower back pain with unintentional 20 lbs. weight loss. Relevant history included a recent trip to Arizona 3 months prior to presentation. On arrival, he was noted to have decreased breath sounds bilaterally, and paraspinal tenderness in the lumbar area. CT scan revealed diffuse pneumonitis and an abscess with osteomyelitis in the sacrum and right iliac bone. Continued respiratory decompensation led him to the intensive care unit where he had a bronchoscopy and later sacroiliac joint fluid collection was performed. Based on his travel history, and elevated serum IgE, liposomal amphotericin B was initiated. Later his antibodies against Coccidiodes resulted elevated and fungal cultures from the bronchoalveolar lavage and abscess from the sacral vertebrae grew mould, morphologically consistent with Coccidiodes posadasii He was transitioned to oral fluconazole and will have a close follow-up outpatient.

A 63-year-old woman with a prior history of chronic lower extremity lymphedema came to the hospital for evaluation of new-onset left leg pain and swelling associated with haemorrhagic blisters and foul-smelling discharge. Relevant history included a recent trip to a Hudson River Valley beach in New York 1 week prior to hospitalisation. Laboratory evaluation revealed significant leukocytosis and lactic acidosis. She was found to have sepsis and bacteremia secondary to Vibrio cholerae (serotype non-O1, non-O139). During a prolonged intensive care unit course requiring intravenous pressor support and broad-spectrum antibiotics, she underwent debridement of her left foot eschar along with skin grafting. Once clinically stable and improved, she was discharged to a subacute rehabilitation centre with close follow-up for wound care. V. cholerae infection is rare and often benign but can be transmitted from contaminated seawater to individuals with underlying chronic illness and cause severe symptoms, including sepsis.

OBJECTIVE: To determine if racial differences are associated with Neonatal Opioid Withdrawal Syndrome (NOWS) severity. STUDY DESIGN: A 10-year (2008-2017) retrospective cohort of infants ≥35 weeks gestation with prenatal exposure to opioids was included. The primary measure was the need for pharmacotherapy. Multivariable logistic regression and propensity score analysis were performed. RESULTS: Among 345 infants with NOWS, 111 (32%) were black infants with 70% of them requiring pharmacotherapy as compared with 84% of white infants. Upon adjusting for significant covariates (methadone, benzodiazepine use, and gestational age), black infants were 57% less likely than whites to require pharmacotherapy (Odds ratio: 0.43, 95%CI: 0.22-0.80, p = 0.009). Similar results were observed with propensity score analysis. CONCLUSIONS: Significant racial disparity observed may be secondary to genetic variations in opioid pharmacogenomics and/or extrinsic factors. Large-scale studies are warranted to include race in predictive models for early pharmacological intervention.

Implementation Lessons 1. Mobile telephony use in the hospital setting is complex and sub-optimal implementation of mobile communication technology can create inefficiencies in clinical workflow 2. Objective measurement of mobile technology's impact on clinical communication workflow is necessary to identify and remediate associated inefficiencies in real-time 3. Functionality between mobile applications and devices should be evaluated when implementing technology, particularly when an application is non-native to a device 4. Continual collaboration between front-line clinicians and technical teams allows for early identification of adverse impacts from, and optimization of, mobile communication technology implementation.

Bouveret syndrome, a rare cause of intestinal obstruction, occurs by passage of a gallstone through a cholecystoduodenal fistula into the intestinal lumen. Presenting symptoms are nausea, vomiting, and abdominal pain. In some cases, chronic symptoms result in weight loss. Typically, the syndrome is diagnosed via x-ray, ultrasound, or computed tomography. Treatment options are endoscopic or surgical. Endoscopic approaches include mechanical lithotripsy, electrohydraulic lithotripsy, stone extraction, laser lithotripsy, extracorporeal shockwave lithotripsy, and/or duodenal stenting. When stone fragments migrate distally, surgical removal becomes necessary. We describe a distinct endoscopic treatment via stone breakage, followed by pushing the fragments of the stone into the jejunum, resolving the intestinal obstruction.
