Purpose: We report a patient with recurrent optic disc pit (ODP) maculopathy after Valsalva's maneuver and discuss its pathophysiology. We also hypothesize the role of Valsalva's maneuver in its genesis.
Method: Case report of one patient, male, 12 years old.
Results: Serous retinal detachment may occur in association with the ODP, a developmental anomaly of the optic nerve head. Histopathologically, it consists of a dysplastic retina herniation into a pocket extending posteriorly through a defect in the lamina cribrosa into the subarachnoid space. These three different compartments-intraocular space, optic nerve head, and subarachnoid space-and the dynamic interactions among them should be understood as the key factors for the occurrence of ODP-related serous retinal detachment.
Conclusion: Based on the possibility that serous retinal detachment secondary to the ODP could be related to the Valsalva's maneuver, we strongly recommend that patients with ODP be advised to avoid intense physical or work activities that may increase abdominal, thoracic, and cerebral pressure and to refrain from playing wind instruments to avoid pretreatment, per treatment, and post-treatment intercurrences.

Hamman's syndrome is characterized by spontaneous pneumomediastinum triggered by Valsalva maneuvers and is an uncommon complication during labor and the postpartum period. It is typically benign and managed conservatively with oxygen therapy and analgesia. We present the clinical case of a 21-year-old primigravida who developed spontaneous pneumomediastinum during labor, manifesting with subcutaneous emphysema and dyspnea.

The Valsalva manoeuvre is widely recognised for its effectiveness in reverting supra-ventricular tachycardia (SVT) in patients with good coordination. However, this is not applicable in sedated ventilated patients and there is a dearth of literature regarding the application of Valsalva in unconscious patients on mechanical ventilation. The authors, for the first time, present a novel non-pharmacological method to treat SVT in critically ill patients on mechanical ventilation, employing the high positive end-expiratory pressure (PEEP) technique.

: Recurrent chronic otitis media (rCOM) is a major cause of hearing impairment, often linked to Eustachian tube (ET) dysfunction. Anatomical abnormalities, such as ET narrowing and obstructions, and functional impairments, including poor pressure regulation, play significant roles in rCOM recurrence. This study aimed to (1) identify anatomical variations of the ET in patients with rCOM using high-resolution imaging; (2) evaluate ET functional status using tympanometry, tubomanometry, and ET function tests; and (3) assess the correlation between anatomical variations and functional impairments in predicting rCOM recurrence.

Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.
Methods: This is a retrospective interventional case report.

Introduction SARS-CoV-2 infection (COVID-19) and the COVID-19 vaccine have been linked to the development of persistent symptoms, including orthostatic intolerance (OI) and postural orthostatic tachycardia syndrome (POTS), in both children and adults. POTS is characterized by excessive tachycardia and other symptoms upon standing, significantly impacting quality of life. This study aims to evaluate the clinical and laboratory findings in pediatric patients with post-COVID-19 or post-COVID-19 vaccine OI and POTS.
