Cryptococcosis and Cryptococcal Meningitis: A Narrative Review and the Up-to-Date Management Approach.

Cryptococcosis is a fungal infectious disease that enormously impacts human health worldwide. Cryptococcal meningitis is the most severe disease caused by the fungus Cryptococcus, and can lead to death, if left untreated. Many patients develop resistance and progress to death even after treatment. It requires a prolonged treatment course in people with AIDS. This narrative review provides an evidence-based summary of the current treatment modalities and future trial options, including newer ones, namely, 18B7, T-2307, VT-1598, AR12, manogepix, and miltefosine. This review also evaluated the management and empiric treatment of cryptococcus meningitis. The disease can easily evade diagnosis with subacute presentation. Despite the severity of the disease, treatment options for cryptococcosis remain limited, and more research is needed.

"Beyond the Bladder: Exploring the Intricacies of Emphysematous Cystitis and Its Surprising Associations".

Emphysematous cystitis is defined by the presence of air within the bladder wall or lumen in imaging studies with increased incidence in elderly women and diabetics. It is a result of gas-forming organisms like Klebsiella and E. coli but can be caused by fungi such as Candida and Aspergillus as well with a wide spectrum of clinical presentations. In this article, we present a case of a 77-year-old female with diabetes mellitus who presented to the hospital with a chief complaint of left lower quadrant abdominal pain. Abdominal imaging revealed emphysematous cystitis, paraspinal abscess, and air in the thoracic and lumbar vertebrae. Laboratory results showed leukocytosis, lactic acidosis, and urinalysis significant for urinary tract infection but no positive urine or blood cultures. The patient was admitted to the intensive care unit for septic shock and was treated with mechanical ventilation, vasopressor support, and prompt antimicrobial therapy following which the requirement of vasopressors ceased on the third day of admission. The decision was then made by the family to pursue hospice care, following which mechanical ventilation was discontinued and the patient transferred to inpatient hospice. With this case report, we aim to add to the existing literature regarding the spread of intra-abdominal infections and go over a brief review of the currently available literature. From our review, we would like to conclude that the presence of pneumoracchis, especially in the setting of an intra-abdominal infection, is a poor prognostic marker, and timely diagnosis and treatment of potential causes are required to reduce mortality.

Update on the Role of FeNO in Asthma Management.

Asthma is a heterogenous disorder characterized by presence of different phenotypes and endotypes. Up to 10% of the individuals suffer from severe asthma and are at increased risk of morbidity and mortality. Fractional exhaled nitric oxide (FeNO) is a cost-effective, point of care biomarker that is used to detect type 2 airway inflammation. Guidelines have proposed to measure FeNO as an adjunct to diagnostic evaluation in individuals with suspected asthma and to monitor airway inflammation. FeNO has lower sensitivity, suggesting that it may not be a good biomarker to rule out asthma. FeNO may also be used to predict response to inhaled corticosteroids, predict adherence and deciding on biologic therapy. Higher levels of FeNO have been associated with lower lung function and increased risk for future asthma exacerbations and its predictive value increases when combined with other standard measurements of asthma assessment.

Comparison of patients admitted to an inner-city intensive care unit across 3 COVID-19 waves.

To expand our limited knowledge of COVID-19-related outcomes in patients admitted to inner-city intensive care unit (ICU across multiple infection waves. This retrospective study compared patients admitted to the ICU in Bronx, NY, during 3 COVID-19 waves (March 2020 to February 2022). Outcomes included in hospital mortality, length of stay (LOS), use of mechanical ventilation, and discharge disposition. The study included 716 patients (343, 276, and 97 in the first, second, and third COVID-19 waves, respectively). The number of days on mechanical ventilation and LOS were lower in the first wave. Of the 345 discharged patients, 37% went home directly, whereas 11% were discharged to a skill nursing facility. More patients went home during the second and third waves. Mortality decreased from the first to the third waves (57%-37%; P < .001). Predictors of mortality included age, male gender, COPD, shock, acute kidney injury (AKI), dialysis requirement, and mechanical ventilation. The decreased mortality and better discharge disposition of these inner-city patients during the second and third waves is encouraging, as this population historically had a high COVID-19-related mortality risk.

Disruption of cardio-pulmonary coupling in myopathies: Pathophysiological and mechanistic characterization with special emphasis on nemaline myopathy.

The heart and lung are in continuous reciprocal interaction that creates a functional and anatomical reserve referred to as cardiopulmonary coupling (CPC). Disruption of CPC can occur due to various cardiac or pulmonary pathologies but also can occur in patients with myopathies. Nemaline myopathy (NM) is a skeletal muscle heterogeneous disorder due to contractile proteins' gene mutations that impact lung and cardiac mechanics and thus is expected to adversely affect CPC in a complex manner. We present a case of NM and we review the literature on cardiac and pulmonary effects of myopathy-related disruption of CPC.

A Rare Case of Reverse Takotsubo Cardiomyopathy in a 28-Year-Old Female in Peripartum Period.

Reverse Takotsubo cardiomyopathy is a rare variant of Takotsubo cardiomyopathy in which ballooning occurs at the base of the heart rather than the apex, which is hyperkinetic. Takotsubo cardiomyopathy is usually considered in postmenopausal women, but a growing number of cases of the reverse variant are emerging in peripartum women. We present a case of peripartum reverse Takotsubo cardiomyopathy in a 23-year-old G1P0 female at 38 weeks gestation, induced by preeclampsia with severe features. An echocardiogram performed in the immediate post-cesarean period demonstrated a severely reduced ejection fraction of 25%, which was improved to 43% over the next 48 hours with diuresis. Therefore, it is imperative to differentiate Takotsubo cardiomyopathy occurring in the peripartum period from peripartum cardiomyopathy, which has a similar clinical presentation, to diagnose this condition and improve patient outcomes.

Hashimoto's Thyroiditis Encephalopathy Induced by COVID-19 Infection.

Various factors can lead to thyroiditis, including any acute inflammatory process, especially viral illness. While coronavirus disease 2019 (COVID-19) has been linked to disorders of various systems, there is a lack of literature showing an association of coronavirus with the cause of Hashimoto's thyroiditis. Several possible mechanisms for this outcome have been proposed; chief among them is molecular mimicry. Here, we are reporting a case of Hashimoto's thyroiditis incited by COVID-19 in a 34-year-old obese female who presented with anxiety, behavioral changes, and repeated head movements. The patient had an elevated thyroid stimulating hormone (TSH) level, a low thyroxine (T4) level, and a positive anti-microsomal antibody screen. The patient also tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA. Ultrasound of the patient's neck showed an enlarged heterogeneous thyroid gland. Thyroid replacement therapy with intravenous levothyroxine was started with the subsequent oral transition. Concurrently, she received antibiotics, steroids, and low-molecular-weight heparin for COVID-19. The patient exhibited significant improvement in her mental status, with an eventual return to baseline. The results of the thyroid panel obtained at the outpatient follow-up were normal. Although there is a paucity of data to show COVID-19 as a cause of this painless thyroiditis, this case demonstrates such causality between these two.

Change in patterns of hospitalization for influenza during COVID-19 surges.

BACKGROUND: Hospitalization due to influenza has been stable in recent years. In March 2020, New York was an epicenter for coronavirus disease 2019 (COVID-19). Because influenza and COVID-19 present similarly, there were serious concerns that coinfection of these viruses would burden the healthcare system. We compared incidence and outcomes of patients hospitalized with influenza before and during COVID-19 (seasons 2017-2021). METHODS: We conducted a retrospective study evaluating hospitalized patients with influenza. Four influenza seasons were evaluated, 2017-2021, pre- and during COVID-19 pandemic. We compared incidence of influenza and clinical outcomes across the seasons. RESULTS: We found 412 patients hospitalized due to influenza in the study period; 394 had influenza, and 18 had both influenza and COVID-19 infections. Demographics across the four influenza seasons were comparable; the cohort was predominantly female (61%) and had an average age of 60 years old. Comorbid conditions were common. No outcome differences were found for patients with influenza when comparing influenza seasons prior to and during the COVID-19 pandemic. The mortality for the entire cohort was 6.5%. During the COVID-19 pandemic, there were 18 (4.4%) influenza patients coinfected with COVID-19 and 32 (7.8%) patients with bacterial super infection. Predictors of mortality in patients with influenza included presence of shock, heart failure, bacterial pneumonia, and use of mechanical ventilation. Coinfection with COVID-19 did not increase mortality. CONCLUSION: We observed a significant decrease in the incidence of hospitalization due to influenza during the COVID-19 pandemic. Clinical presentations and outcomes for patients with influenza remain stable. Being aware of possible increased mortality for patients with both influenza and bacterial pneumonia is important. Although coinfection with COVID-19 did not increase mortality in influenza patients, identifying the specific virus responsible for infections has major therapeutic implications.

Complicated Chikungunya Infection in Tertiary ICU in Western India - A Prospective Study Over 3 Years.

BACKGROUND: Chikungunya is a globally spreading infectious arboviral disease transmitted from a diurnal bite of the Aedes aegypti and Aedes albopictus Mosquitoes. It is a disease with sporadic outbreaks. It is now resurfacing in South East Asia especially in India, where it is found to have high mortality and morbidity and presenting with atypical presentation, especially with the neurotropic presentation. OBJECTIVE: To review clinical profile of patients who required admission in the Intensive care unit with atypical presentation of Chikungunya and to study their clinical spectrum and outcome over a course of three years in India. METHOD AND FINDINGS: Using Established guidelines, we conducted a prospective study in a Tertiary care center where we identified patients who required intensive care admissions and were admitted with complicated chikungunya infection and then evaluated their clinical progression of the disease. CONCLUSION: CHIKV infection is rapidly emerging in more than 100 countries and more and more atypical serious neurological manifestations are seen in elderly populations. Many of these patients have high morbidity and mortality.

Drug-Induced Deafness: A Rare Case of Bilateral Sensorineural Hearing Loss Following Speedballing.

Many users of recreational drugs use cocaine and opioids together, often called "speedballing." Hearing loss is a rarely reported adverse effect following recreational drug abuse. Only one case has been reported in history with hearing loss caused by speedballing. Here, we present the case of a 38-year-old female who presented with speedball abuse and new-onset bilateral hearing loss to the emergency department. A computed tomography scan of the head was unremarkable. She was treated with thiamine, folate, multivitamins, and intravenous fluids. The hearing loss improved without any acute intervention. The significance of sudden hearing loss due to recreational drug use is highlighted by this case. Apart from a few animal studies, there is no detailed research explaining the pathophysiology of speedball-induced hearing loss. Further studies and trials are needed to better understand the effects of combined and separate cocaine and opioid use on audiologic physiology.
