ABSTRACT
Pneumomediastinum can be primary (spontaneous) or secondary to iatrogenic, traumatic, and non-traumatic causes. The incidence of spontaneous and secondary pneumomediastinum is higher in patients with coronavirus disease 2019 (COVID-19) compared to the general population. So, pneumomediastinum should be considered in the differential diagnosis of any patient with COVID-19 presenting with chest pain and breathlessness. A high level of suspicion is required to diagnose this condition promptly. Unlike in other disease conditions, pneumomediastinum in COVID-19 has a complicated course with higher mortality in intubated patients. No guidelines exist for managing pneumomediastinum patients with COVID-19. Therefore, emergency physicians should be aware of the various treatment modalities besides conservative management for pneumomediastinum and life-saving interventions for tension pneumomediastinum.
ABSTRACT
Objective Spontaneous subarachnoid hemorrhage (SAH) is a neurological condition that causes significant morbidity and mortality. It is known to have regional differences in its incidence. Indian studies have shown conflicting results about the incidence of aneurysms as the cause of SAH, varying from 35% to 80%. The data available on the epidemiology of spontaneous SAH in the South Indian population are very few. Our study aims to describe the clinical profile of patients presenting with spontaneous SAH to the emergency department in a tertiary center in South India and describe the factors influencing the clinical outcome. Materials and Methods The study included 75 patients diagnosed with spontaneous SAH in our emergency department. Demographic data, medical history, details about the first medical contact, clinical features at admission, complications during the hospital stay, and interventions underwent were recorded. The study participants were followed-up at 6 weeks after discharge from hospital to assess the neurological outcome based on modified Rankin Scale (mRS) score, using a 9-point questionnaire. Results Of the 75 patients with spontaneous SAH, the majority were females, and in the age group of 50 to 69 years. The median time to first medical contact was observed to be 2 hours; and SAH was diagnosed at the first medical contact only in 37% of the patients. Hypertension was the most common comorbid condition associated with SAH (53%). Almost 80% of the patients who underwent angiographic studies had aneurysmal SAH (aSAH). Hydrocephalus was the most common complication seen in 37% of the patients, followed by hyponatremia (28%) and vasospasm (25%). At the time of follow-up after 6 weeks, we found that 36% of the patients were having a neurologically favorable outcome with an mRS score of 0 to 2, 8% of patients were having moderate to severe disability (mRS 3 to 5) and were living a dependent life. The mortality rate (mRS 6) was observed to be around 50% (6% lost to follow-up). Conclusion We observed a relatively higher incidence of aneurysmal rupture among the patients with spontaneous SAH in our region. The misdiagnosis rate at first medical contact was higher. The mortality rate was observed to be around 50% at 6 weeks. Loss of consciousness at ictus, aneurysmal rupture, WFNS grades IV-V, hydrocephalus, vasospasm, hypernatremia, and delayed cerebral ischemia were found to be the mortality predictors in SAH.
ABSTRACT
Effusive pneumothorax can be hemopneumothorax, pyopneumothorax, or hydropneumothorax depending on the type of fluid compartment within the pleural cavity. Hydropneumothorax is the abnormal collection of air and serous fluid within the pleural cavity. Here, we report a case of a 34-year-old male who presented to the emergency department with cough and breathlessness. We did bedside point-of-care ultrasound-assisted clinical evaluation as the patient was vitally unstable, which showed "hydro point" and "defective barcode sign," which suggested hydropneumothorax. We present these clinical evaluation details, imaging/sonographic findings, and patient management in this case report.
ABSTRACT
Effusive pneumothorax is an abnormal collection of air and fluid within the pleural space: blood, pus, or serous fluid. Thus, effusive pneumothorax can be categorized as hemopneumothorax, pyopneumothorax, or hydropneumothorax, depending on the type of fluid accumulation. Hydropneumothorax is a clinical condition defined by the presence of air and serous fluid within the pleura space. Hydropneumothorax is one of the common respiratory emergencies encountered in the emergency department in India. Etiologies can be classified into infectious and non-infectious causes, among which tuberculosis being the most common one. Point of care ultrasound (POCUS) can help diagnose hydropneumothorax at the bedside rather than shift the patient for an X-ray. Here, we describe a case of hydropneumothorax, which was diagnosed using POCUS by characteristic sonographic signs, namely "Hydro-point" and "barcode-hydro point-sinusoidal sign." Sonographic hydro-point is the transition zone of the air-fluid interface, which is seen in hydropneumothorax. Targhetta et al., in 1992, introduced the term "Hydro-point" in lung ultrasound for diagnosing hydropneumothorax but has been under-reported/unspoken much in the literature. With the use of POCUS, we diagnosed and stabilized the patient in the Emergency Department.
