- Utility of Point of Care Ultrasound in Humanitarian Assistance Missions(2021) SULLIVAN, L. T. John F.; POLLY, Matheus; ROMAN, L. C. D. R. John W.; MILDER, C. A. P. T. Edmund A.; CARTER, C. D. R. Rachel E.; LENNON, L. C. D. R. Robert P.Introduction: Point of care ultrasound (POCUS) is increasingly used in primary care in the USA and has been shown to provide significant benefit to care in deployed military settings and during disaster relief efforts. It is less studied as a tool during humanitarian assistance missions. We sought to determine the utility of POCUS in a humanitarian assistance setting during the February 2019 joint U.S.-Brazilian hospital assistance mission aboard the Hospitalar Assistance Ship Carlos Chagas along the Madeira River in the Brazilian Amazon. Materials and Methods: Point of care ultrasound was offered as a diagnostic modality to primary care physicians during the course of a monthlong mission. A handheld IVIZ ultrasound machine was loaned for use during this mission by Sonosite. A P21v phased array (5-1 MHz) or an L38v linear (10-5 MHz) transducer was used for scanning. Requests for POCUS examinations, their findings, and changes in patient management were recorded. Results: Point of care ultrasound examinations were requested and performed in 24 of 814 (3%) outpatient primary care visits. Ten of these studies (42% of POCUS examinations, 1.2% of all patient visits) directed patient management decisions, in each case preventing unnecessary referral. Conclusions: In this austere setting, POCUS proved to be an inexpensive, effective tool at preventing unnecessary referrals. Future medical humanitarian assistance missions may likewise find POCUS to be a primary care force-multiplier.
- Impact of the COVID-19 pandemic on the incidence of multidrug-resistant bacterial infections in an acute care hospital in Brazil(2022) POLLY, Matheus; ALMEIDA, Bianca L. de; LENNON, Robert P.; CORTES, Marina Farrel; COSTA, Silvia F.; GUIMARAES, ThaisBackground: The impact of COVID-19 on healthcare- associated infections (HCAI) caused by multidrug-resistant (MDR) bacteria that contribute to higher mortality is a growing area of study Methods: This retrospective observational study compares the incidence density (ID) of HCAI caused by MDR bacteria (CRE, CRAB, CRP, MRSA and VRE) pre-COVID (2017-2019) and during the COVID-19 pandemic (2020) in overall hospitalized patients and in intensive care (ICU) units. Results: We identified 8,869 HCAI, of which 2,641 (29.7%) were caused by bacterial MDR, and 1,257 (14.1%) were from ICUs. The overall ID of MDR infections increased 23% (P < .005) during COVID-19. The overall perpathogen analysis shows significant increases in infections by CRAB and MRSA (+108.1%, p<0.005; +94.7%, p<0.005, respectively), but not in CRE, CRP, or VRE. In the ICU, the overall ID of MDR infections decreased during COVID, but that decline was not significant (-6.5%, P = .26). The ICU per-pathogen analysis of ID of infection showed significant increases in CRAB and MRSA (+42.0%, P = .001; +46.2%, P = .04), significant decreases in CRE and CRP (-26.4%, P = .002; -44.2%, P = 0.003, respectively) and no change in VRE. Conclusions: The COVID-19 pandemic correlates to an increase in ID of CRAB and MRSA both in ICU and nonICU setting, and a decrease in ID of CRE and CRP in the ICU setting. Infection control teams should be aware of possible outbreaks of CRAB and MRSA and promote rigorous adherence to infection control measures as practices change to accommodate changes in healthcare needs during and after the pandemic.
- Meningitis in the Guise of Dementia: Lyme-Induced Normal Pressure Hydrocephalus(2023) LIU, Ryan; POLLY, Matheus; LENNON, Robert P.; REEDY-COOPER, AlexisWhile the cause of altered mentation in the elderly may be multifactorial, infectious etiologies may be missed. This case report aims to detail an account of a patient with dementia, found to have Lyme meningitis in the setting of a normal pressure hydrocephalus (NPH). The patient smelled of urine and presented with ambulatory dysfunction, fitting the ""wet, wacky, and wobbly"" triad of NPH while also having subjective chills and leukocytosis. Non-contrast brain CT scan showed dilated ventricles. Cerebrospinal fluid (CSF) studies suggested aseptic meningitis. Serum studies using a modified twotiered algorithm confirmed the diagnosis of Lyme disease.Treatment of the underlying condition with a prolonged course of doxycycline improved symptoms and clinical course. Review of the literature on the association between Lyme meningitis and NPH reveals that few cases of Lyme-related NPH have been reported worldwide and further research into the pathophysiology, diagnostic approach, treatment modalities, and management of NPH secondary to Lyme meningitis may be warranted.
- A Rare Association of Chronic Pulmonary Aspergillosis and Pulmonary Cryptococcosis as an Underlying Risk Factor(2023) SEKIGUCHI, William Kazunori; ALBUQUERQUE, Ronniel Morais; RAPOZO, Marjorie Marini; POLLY, Matheus; NASTRI, Ana Catharina de Seixas Santos; MAGRI, Marcello Mihailenko Chaves; OLIVEIRA, Vitor Falcao de; BERNARDI, Fabiola del Carlo; SOTTO, Mirian Nacagami
- Monkeypox Virus Transmission to Healthcare Worker through Needlestick Injury, Brazil(2022) CARVALHO, Laina Bubach; CASADIO, Luciana V. B.; POLLY, Matheus; NASTRI, Ana Catharina; TURDO, Anna Claudia; ELIODORO, Raissa H. De Araujo; SABINO, Ester Cerdeira; LEVIN, Anna Sara; PROENCA, Adriana Coracini Tonacio de; HIGASHINO, Hermes RyoitiWe describe monkeypox virus (MPXV) transmission from a patient to a healthcare worker through needlestick injury. A lesion appeared at the inoculation site 5 days after inju-ry. Blood tested MPXV-positive by PCR before symptoms worsened; blood remained MPXV-positive at discharge 19 days after symptom onset. Postexposure prophylaxis could prevent potential MPXV bloodborne transmission.
