Clinically significant anticardiolipin antibodies associated with COVID-19.

The novel coronavirus strain known as SARS-CoV-2 has rapidly spread around the world creating distinct challenges to the healthcare workforce. Coagulopathy contributing to significant morbidity in critically ill patients with SARS-CoV-2 has now been well documented. We discuss two cases selected from patients requiring critical care in April 2020 in New York City with a unique clinical course. Both cases reveal significant thrombotic events noted on imaging during their hospital course. Obtaining serial inflammatory markers in conjunction with anti-phospholipid antibody testing revealed clinically significant Antiphospholipid syndrome (APS). This case series reviews the details preceding APS observed in SARS-CoV-2 and aims to report findings that could potentially further our understanding of the disease.

Patient-nephrologist prognostic awareness and discordance in end stage renal disease on renal replacement therapy.

PURPOSE: The 1-year mortality rate of patients with end-stage renal disease (ESRD) on renal replacement therapy (RRT) is 20-25% comparable to many cancers. Studies have shown that cancer patients commonly overestimate their likelihood of survival relative to their physicians. It is unclear if this translates into other terminal illnesses. METHODS: Adult and elderly patients with ESRD on RRT without cognitive defect were interviewed to evaluate their prognostic estimates at 1 and 5 years. Past medical history and demographic data was abstracted from their medical charts. Each patient's proper nephrologist was then interviewed regarding his proper prognostic estimate for this patient. Both the patient and the nephrologist's estimates were compared and a difference of greater than 20% was defined as the threshold for prognostic concordance. RESULTS: 77% of patients were found to be in prognostic discordance with their nephrologists. This group was older, had more comorbidities, a lower albumin level and a poorer prognosis. The majority of patients were in disagreement with their nephrologists regarding whether a discussion about prognosis had taken place. The choice of end of life care for 55% of patients was focused on relieving pain and discomfort. CONCLUSION: Communication of prognosis and discussions related to life expectancy and end of life care are lacking in the routine care of ESRD patients. ESRD patients therefore tend to overestimate their prognosis which might lead to overutilization of invasive procedures with increased acute healthcare costs as well as a delay in instigation of palliative or hospice measures.

Primary Pulmonary Hodgkin's Lymphoma: A Rare Etiology of a Cavitary Lung Mass.

Primary pulmonary Hodgkin's lymphoma (PPHL) is an uncommon disease. This entity is different from Hodgkin's lymphoma with parenchymal or nodal lung involvement. In this report, we highlight the case of a young female presenting with a six-month history of a productive cough and constitutional B symptoms. Imaging showed cavitary lesions in the right-upper and right-middle lobes. The initial comprehensive infectious workup was negative. Histopathology and immunochemistry confirmed the diagnosis of PPHL. PPHL is an uncommon etiology of cavitary lung lesions. Despite its diagnostic difficulties, awareness of such a disease is crucial, given its high rate of response to treatment, especially in the young population.

Vanishing Lung Syndrome: Compound Effect of Tobacco and Marijuana Use on the Development of Bullous Lung Disease - A Joint Effort.

Marijuana use has been increasing across the United States due to its legalization as both a medicinal and recreational product. A small number of case reports have described a pathological entity called vanishing lung syndrome (VLS), which is a rare bullous lung disease usually caused by tobacco smoking. Recent case reports have implicated marijuana in the development of VLS. We present a case of a 47-year-old man, who presented to our hospital with shortness of breath, fevers and a productive cough. On physical exam, he was tachypneic with audible stridor and absent right sided breath sounds. Laryngoscopy showed a retropharyngeal abscess, and chest radiography showed a possible right pneumothorax. Chest computed tomography (CT) showed bilateral bullous emphysematous lung disease with a giant bulla occupying most of his right lung field. He was placed on mechanical ventilation and treated with broad spectrum antibiotics in the intensive care unit, where he developed acute respiratory distress syndrome (ARDS). He continued to decline, and developed disseminated intravascular coagulation, after which he succumbed to his disease.

What we know about surgical therapy in early-stage non-small-cell lung cancer: a guide for the medical oncologist.

Lung cancer remains the leading cause of death in cancer patients. The gold standard for the treatment of early-stage non-small-cell lung cancer is lobectomy with mediastinal lymph-node dissection or systematic lymph-node sampling. The evidence behind this recommendation is based on the sole randomized controlled trial conducted to date, done by the Lung Cancer Study Group and published in 1995, which found a superiority for lobectomy over sublobar resection with regard to local recurrence rate and improved survival. The population studied at that time were medically fit patients at low risk for surgery with a stage IA non-small-cell lung carcinoma, ie, a solitary tumor less than 3 cm in size. In practice, however, thoracic surgeons have continued to push the limit of a more conservative surgical resection in this patient population. Since then, several retrospective studies have attempted to identify the ideal population to benefit from sublobar resection without it affecting survival or local recurrence. Several variables have been studied, including tumor size, patient age, surgical approach, histological and radiological properties, and optimal surgical resection margin, as well as promising prognostic biomarkers. In this review, we summarize the data available in the literature regarding the surgical approach to patients with stage IA non-small-cell lung cancer studying all the aforementioned variables.

FDG-PET-positive lower-extremity sebaceous-gland carcinoma in a patient with Muir-Torre syndrome.

Sebaceous-gland carcinoma can occur alone or as one of the defining features of the Muir-Torre syndrome. Cases occurring below the head and neck are extremely rare. Here we describe the case of a 70-year-old male with Muir-Torre syndrome who had a recurrent sebaceous-gland carcinoma in the left lower extremity that demonstrated (18)F-FDG avidity. An (18)F-FDG-avid lower-extremity sebaceous-gland carcinoma has not been previously reported.
