Background: Although flexible endoscopy is effective for intraventricular lesions, it is less frequently used for hemorrhagic cases. In some hemorrhagic strokes, blood clots may plunge into the cerebral aqueduct and cause acute obstructive hydrocephalus. A flexible endoscope can aspirate clots and prevent acute hydrocephalus.
Methods: Here, we report four cases of hemorrhage: one of intracerebral hemorrhage and three of subarachnoid hemorrhages.
Results: In all cases, acute hydrocephalus was not apparent upon admission. Sudden comatose occurred; computed tomography revealed acute obstructive hydrocephalus with a strangulated clot in the cerebral aqueduct. We performed aspiration of the strangulated clot using a flexible endoscope. Consciousness improved in all cases, and acute hydrocephalus was prevented in all cases.
Conclusion: The use of simple flexible endoscopic aspiration for clots might be a beneficial and less-invasive procedure for acute obstructive hydrocephalus caused by a small clot with hemorrhagic stroke.

Background: Allergic rhinitis (AR) and acute non-allergic rhinosinusitis (ARS) often present with similar symptoms. While these are generally differentiated by history and occasionally by secretion cell counts, there are few data temporally comparing these conditions.
Methods: A prospective, observational study was conducted to assess nasal mucus properties, nasal obstruction, nasal secretion cells, and health related QOL during the acute phase (Day 5) and during a later phase of illness (Day 14/28).

The aim of this retrospective cohort study was to investigate the clinical characteristics and the outcomes of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) patients between different sex. We aimed to collect the first hospitalization patients who were diagnosed as AECOPD between 1 January 2019 to 31 December 2021 from the general ward and intensive care unit in the hole hospital, Shanghai the Fifth People's Hospital, Fudan University. Demographic data, initial clinical symptoms, on-admission vital signs, comorbidities, laboratory tests and imaging examination, treatment, and follow-up were compared between the two groups.

Introduction: Environmental changes and modifications in leisure habits have facilitated the emergence of new bacteria responsible for causing ear infections with different presentations. In this context, Turicella otitidis is a pathogen for which isolated cases of external and middle ear infections have been reported. However, our experience indicates a resurgence in its occurrence in recent years.

We aimed to design a diagnostic decision support which classifies dyspnoeic ED visits into acute heart failure (AHF), exacerbation of chronic obstructive pulmonary disease (eCOPD), pneumonia and "other diagnoses" by using deep learning and complete, unselected data from an entire regional health care system.
Methods: In this cross-sectional study, we included all dyspnoeic ED visits of patients ≥ 18 years of age at the two EDs in the region of Halland, Sweden, 07/01/2017-12/31/2019.
Tailored Therapies for Cardiogenic Shock in Hypertrophic Cardiomyopathy: Navigating Emerging Strategies.

Hypertrophic cardiomyopathy (HCM) is a complex and heterogeneous cardiac disorder, often complicated by cardiogenic shock, a life-threatening condition marked by severe cardiac output failure. Managing cardiogenic shock in HCM patients presents unique challenges due to the distinct pathophysiology of the disease, which includes dynamic left ventricular outflow tract obstruction, diastolic dysfunction, and myocardial ischemia. This review discusses current and emerging therapeutic strategies tailored to address the complexities of HCM-associated cardiogenic shock and other diseases with similar pathophysiology that provoke left ventricular outflow tract obstruction.
