Recurrent Meningitis.

PURPOSE OF REVIEW: Recurrent meningitis is a rare clinical scenario that can be self-limiting or life threatening depending on the underlying etiology. This review describes the causes, risk factors, treatment, and prognosis for recurrent meningitis. As a general overview of a broad topic, the aim of this review is to provide clinicians with a comprehensive differential diagnosis to aide in the evaluation and management of a patient with recurrent meningitis. RECENT FINDINGS: New developments related to understanding the pathophysiology of recurrent meningitis are as scarce as studies evaluating the treatment and prevention of this rare disorder. A trial evaluating oral valacyclovir suppression after HSV-2 meningitis did not demonstrate a benefit in preventing recurrences. The data on prophylactic antibiotics after basilar skull fractures do not support their use. Intrathecal trastuzumab has shown promise in treating leptomeningeal carcinomatosis from HER-2 positive breast cancer. Monoclonal antibodies used to treat cancer and autoimmune diseases are new potential causes of drug-induced aseptic meningitis. Despite their potential for causing recurrent meningitis, the clinical entities reviewed herein are not frequently discussed together given that they are a heterogeneous collection of unrelated, rare diseases. Epidemiologic data on recurrent meningitis are lacking. The syndrome of recurrent benign lymphocytic meningitis described by Mollaret in 1944 was later found to be closely related to HSV-2 reactivation, but HSV-2 is by no means the only etiology of recurrent aseptic meningitis. While the mainstay of treatment for recurrent meningitis is supportive care, it is paramount to ensure that reversible and treatable causes have been addressed for further prevention.

The Evolution of Cardiovascular Ultrasound: A Review of Cardiac Point-of-Care Ultrasound (POCUS) Across Specialties.

The use of cardiac point-of-care ultrasound (POCUS) is now widespread in clinics, emergency departments, and all areas of the hospital. Users include medical trainees, advanced practice practitioners, and attending physicians in many specialties and sub-specialties. Opportunities to learn cardiac POCUS and requirements for training vary across specialties, as does the scope of the cardiac POCUS examination. In this review, we describe both a brief history of how cardiac POCUS emerged from echocardiography and the state of the art across a variety of medical fields.

The Focused Assessment with Sonography in Cancer (FASC) Examination.

Malignant effusions occur frequently in patients with cancer and are important to diagnose and treat. In this report, we describe a novel point-of-care ultrasound (POCUS) protocol to rapidly identify pleural effusion, pericardial effusion, and ascites: The Focused Assessment with Sonography in Cancer (FASC). This protocol utilizes six standard sonographic positions to identify the presence of fluid in common anatomic spaces. The FASC examination is intended for widespread use by oncologists and other clinicians who treat patients with cancer.

Internal Medicine Resident Work Absence During the COVID-19 Pandemic at a Large Academic Medical Center in New York City.

BACKGROUND: Montefiore Medical Center (MMC) is a large tertiary care center in the Bronx, New York City, with 245 internal medicine residents. Beginning on February 29, 2020, residents became ill with COVID-19-like illness (CLI), which required absence from work. There was initially a shortage of personal protective equipment and delays in SARS-CoV-2 testing, which gradually improved during March and April 2020. OBJECTIVE: We evaluated the relationship between CLI-related work absence rates of internal medicine residents and MMC's COVID-19 hospital census over time. METHODS: Data on resident work absence between February 29 and May 22 were reviewed along with MMC's COVID-19 hospital census data. To determine the effect of patient exposure on resident CLI incidence, we compared the mean incidence of CLI per patient exposure days (PED = daily hospital census × days pre- or post-peak) before and after peak COVID-19 hospital census. RESULTS: Forty-two percent (103 of 245) of internal medicine residents were absent from work, resulting in 875 missed workdays. At the peak of resident work absence, 16% (38 of 245) were out sick. Residents were absent for a median of 7 days (IQR 6-9.5 days). Mean resident CLI incidence per PED (CLI/PED) was 13.9-fold lower post-peak compared to pre-peak (P = .003). CONCLUSIONS: At the beginning of the COVID-19 pandemic in New York City, a large portion of internal medicine residents at this single center became ill. However, the incidence of CLI decreased over time, despite ongoing exposure to patients with COVID-19.

Recurrent rheumatoid pleural effusions complicated by Mycobacterium heckeshornense infection.

A 41-year-old man with rheumatoid arthritis (RA) presented with worsening dyspnea and deconditioning. He had recently been treated with adalimumab for rheumatoid pleural effusions but developed non-tuberculous mycobacterial pleurisy due to Mycobacterium heckeshornense. Despite therapy with appropriate anti-mycobacterial agents, he ultimately required video assisted thoracoscopy for decortication. While Mycobacterium heckeshornense has been reported to cause infection in multiple sites including the lung, this is the first case to our knowledge of infection confined to the pleural space. Rheumatoid pleural effusions can be complex and difficult to treat, especially when complicated by mycobacterial infection.

Giant left atrium encountered during right-sided thoracentesis.

Giant left atrium is an uncommon pathology to encounter during bedside chest ultrasound, but is an important structure to be aware of when considering thoracentesis. This cardiac structure could easily be mistaken for loculated pleural fluid. This case also supports growing evidence that expert users can safely perform thoracentesis without completely reversing therapeutic anticoagulation.

Ultrasound-Guided Peripheral Intravenous Catheters to Reduce Central Venous Catheter Use on the Inpatient Medical Ward.

PURPOSE: The traditional technique of placing a peripheral intravenous (IV) catheter is successful in most cases on inpatient wards. However, when the traditional method fails, a central venous catheter may be placed to maintain IV access. These catheters are associated with risks including central line-associated bloodstream infection. METHODS: We evaluated the effectiveness and acceptability of an ultrasound-guided peripheral IV service to reduce the number of newly placed central venous catheters on an inpatient ward. Central venous catheters were counted daily on intervention and control wards using a standard protocol, and rates of newly placed catheters were compared using a Poisson regression model. Nurses were surveyed to assess acceptability and perceived benefit. RESULTS: We found a reduction in the rate of newly placed central venous catheters on the intervention unit compared with the control unit at 90 days: mean 0.47 versus 0.67 newly placed central venous catheters/day, but the difference was not significant (P = .08). Nurses were in favor of the ultrasound-guided IV service, with perceived benefit to their patients. CONCLUSION: Ultrasound-guided peripheral IV might reduce unnecessary central venous catheters on general inpatient wards. A portable ultrasound used for this purpose was found to be acceptable by nursing staff.

Fungemia caused by Aureobasidium pullulans in a patient with advanced AIDS: a case report and review of the medical literature.

INTRODUCTION: Aureobasidium pullulans is a dematiaceous, yeast-like fungus that is ubiquitous in nature and can colonize human hair and skin. It has been implicated clinically as causing skin and soft tissue infections, meningitis, splenic abscesses and peritonitis. We present, to our knowledge, the second case of isolation of this organism in a patient with AIDS along with a review of the literature on human infection with A. pullulans. CASE PRESENTATION: A 49-year-old man with advanced AIDS and a history of recurrent oesophageal candidiasis was admitted with nausea with vomiting, and odynophagia. He was treated as having a recurrence of oesophageal candidiasis. Given prior Candida albicans isolate susceptibilities and chronic suppression with fluconazole, he was started on micafungin with eventual improvement in his symptoms. A positive blood culture from admission was initially reported to be growing yeast, but four days later the isolate was recognized as a dematiaceous fungus. The final identification of A. pullulans was not available until 1 month after admission. He had completed a 3-week course of micafungin prior to the identification of the isolate, and repeat cultures were negative. CONCLUSION: A. pullulans fungemia is rare but can occur in patients with immune suppression or indwelling catheters. The significance of isolating A. pullulans from a blood culture in terms of whether it is the causative agent of a state of disease often cannot be determined because skin colonization is possible. Further work is needed to clarify the clinical implications of A. pullulans fungemia.
