Coccidioidomycosis is a fungal infection of the Western hemisphere that is endemic to the soil in areas with limited rainfall. Human and animal infections result with inhalation of arthroconidia. Most often, this is an asymptomatic event. When illness occurs, it is primarily a pneumonic presentation. A small minority of infections eventuate in disseminated disease. Predominately, this presents as meningitis or osteoarticular or integumentary disease. Treatment may not be required for the mildest illness. Azoles are commonly prescribed. Severe infections may require amphotericin B.

Background: Continuous positive airway pressure (CPAP) is the gold standard of care in providing non-invasive positive pressure support to neonates in respiratory distress in high-resource settings. While safety has been demonstrated in low-resource settings, there is a lack of knowledge on the barriers and facilitators to proper implementation.Objective: To identify and describe the barriers, facilitators, and priorities for future implementation of CPAP for neonates and infants in low-resource settings.Methods: A systematic search (database inception to March 6, 2020) was performed on MEDLINE, Embase, Web of Science, CINAHL, Global Health, and the WHO Global Index Medicus using PRISMA-ScR guidelines. Original research articles pertaining to implementation of CPAP devices in low-resource settings, provider or parent perspectives and experiences with CPAP, cost-benefit analyses, and cost-effectiveness studies were included. Inductive content analysis was conducted.Findings: 1385 article were screened and 54 studies across 19 countries met inclusion criteria. Six major themes emerged: device attributes, patient experiences, parent experiences, provider experiences, barriers, and facilitators. Nasal trauma was the most commonly reported complication. Barriers included unreliable electricity and lack of bioengineering support. Facilitators included training, mentorship and empowerment of healthcare providers. Device design, supply chain infrastructure, and training models were imperative to the adoption and sustainability of CPAP.Conclusion: Sustainable implementation of CPAP in low resource settings requires easy-to-use devices, ready access to consumables, and holistic, user-driven training. Further research is necessary on standardizing metrics, interventions that support optimal provider performance, and conditions needed for successful long-term health system integration.

Early studies have reported various electrolyte abnormalities at admission in patients with severe COVID-19. 104 out of 193 patients admitted to our institution presented with hypermagnesemia at presentation. It is believed this may be important in the evaluation of severe SARS-CoV-2 infections. This study evaluated the outcomes of hypermagnesemia in patients with COVID-19. A retrospective chart review of patients admitted to the hospital with confirmed SARS-CoV-2 infection was conducted. A review of the medical literature regarding hypermagnesemia, magnesium levels in critical care illness and electrolyte abnormalities in patients with COVID-19 was performed. Differences in demographic and clinical characteristics of patients with hypermagnesemia and normomagnesemia were evaluated using descriptive statistics. Other known variables of disease severity were analyzed. 104 patients (54%) were identified with hypermagnesemia (≥2.5 mg/dL). 48 of those patients were admitted to the intensive care unit (46%, p<0.001). 34 patients required ventilator support (32%, p<0.0001). With age-adjusted logistic regression analysis hypermagnesemia was associated with mortality (p=0.007). This study demonstrates that hypermagnesemia is a significant marker of disease severity and adverse outcome in SARS-CoV-2 infections. We recommend serum magnesium be added to the panel of tests routinely ordered in evaluation of severe SARS-CoV-2 infections.

Coccidioidomycosis is the second most common endemic fungal infection in the United States. Prior descriptions of coccidioidal peritonitis include only single cases. We describe 17 new cases previously unreported from healthcare institutions in California. The majority of cases presented with nonspecific abdominal complaints. PubMed and Google Scholar were searched for additional case series and only single case reports and reviews of single cases were found. The diagnosis was confirmed by culture or histopathology and/or serology in each patient. All patients were treated with anti-fungal therapy. This case series demonstrates that coccidioidal peritonitis may be asymptomatic or present with only subtle abdominal symptoms. In a minority of our patients, the diagnosis was established incidentally during surgery. Based on this series, the overall outcome of coccidioidal peritonitis is favorable with long-term triazole treatment. The term cure is not usually used in disseminated coccidioidal disease because of the risk of late relapse.

Calciphylaxis is a rare and serious complication of chronic renal failure characterized by vascular calcium overload. It has a high mortality rate. Penile calciphylaxis is an extremely rare condition of penile necrosis due to calciphylaxis of the penile arterioles. Presented here is a severe case of systemic calciphylaxis initially presented as penile necrosis treated with sodium thiosulfate and amputation.
