To support the global restart of elective surgery, data from an international prospective cohort study of 8492 patients (69 countries) was analysed using artificial intelligence (machine learning techniques) to develop a predictive score for mortality in surgical patients with SARS-CoV-2. We found that patient rather than operation factors were the best predictors and used these to create the COVIDsurg Mortality Score (https://covidsurgrisk.app). Our data demonstrates that it is safe to restart a wide range of surgical services for selected patients.

Coccidioidomycosis is an infection caused by soil-dwelling fungi, Coccidioides, that are endemic to the southwestern United States, northern Mexico, and scattered areas of Latin America. It typically presents with pulmonary manifestations that resemble symptoms of bronchitis, pneumonia, and the flu. Extrapulmonary manifestations that involve the skin, lymph nodes, bones, and joints have also been well described, but disseminated coccidioidomycosis initially presenting as chest wall infection without pulmonary symptoms is not. In this article, we present a case of a 33-year-old man who presented with chest wall swelling and eventually diagnosed with chest wall abscesses due to disseminated coccidioidomycosis. We propose that consideration of disseminated coccidioidomycosis in nonresolving swelling, mass, lesions, or abscess especially in endemic areas for coccidioidomycosis and in travelers to the endemic area may prevent the progression and further complications of coccidioidomycosis.

The incidence of wound botulism in injection drug users has increased since the introduction of black tar heroin. Many species of the Clostridium genus, most commonly Clostridium botulinum, Clostridium baratii, and Clostridium butyricum, have been associated with wound botulism. Patients often present with progressive bulbar weakness, including dysphagia, cranial nerve palsies, and loss of speech, in addition to symmetrical descending weakness of the upper extremities that may progress to the chest and lower extremities. In this article, we present 3 cases of wound botulism, in which the patients presented with bulbar weakness and were treated with botulism antitoxin heptavalent. The time to antitoxin administration and its effect on the patients’ clinical courses is compared.

Hypertrophic cardiomyopathy (HCM) is a common disease that can be acquired due to chronic hypertension or via autosomal dominant inheritance. Several patterns of HCM have been described, of which a rare variant is apical hypertrophic cardiomyopathy (AHCM). Atrial thrombus is a well-recognized complication of HCM especially in the setting of atrial fibrillation (AF). However, left ventricular thrombus (LVT) formation is not nearly as prevalent as atrial thrombus. Here is a case of a 57-year-old Hispanic female with AHCM who presented with significant unintentional weight loss and unexplained anemia and was subsequently found to have a large left intraventricular mass suspicious for a tumor vs. ventricular thrombus. The diagnosis was complicated due to the large size of the mass and presenting symptoms suspicious of malignancy.

Coccidioidomycosis is an infection caused by inhalation of arthroconidia of Coccidioides. Forty percent of patients will develop mild and self-limited respiratory infection, and a small fraction of these individuals will develop extrapulmonary disseminated disease. This is the case of a patient with a known history of disseminated coccidioidomycosis, who initially presented for symptoms of persistent pneumonia. On evaluation, the patient was found to have a hepatic abscess for which he underwent percutaneous drainage. Culture grew Coccidioides immitis, and the patient was treated with systemic antifungal. This is a rare case of disseminated coccidioidomycosis in the liver.
