RESUMEN
Glomangiopericytoma (GPC) is a rare benign sinonasal tumor originating from Zimmerman's Pericytes surrounding capillaries and accounting for less than 0.05% of all sinonasal tumors. Glomangiopericytoma has low malignant potential (5-10%) and is mostly diagnosed in the 6th or 7th decade of age with slight female preponderance. We presented here a case series of 5 patients with sinonasal GPC. This research was conducted at a tertiary healthcare centre in North India. In our case series, all the patients were evaluated and underwent endoscopic surgical resection. All patients underwent digital subtraction angiography (DSA) and preoperative embolization. The coblation technique used for haemostasis proved very effective and time-saving. All patients exhibited cytoplasmic SMA positivity (a marker of GPC) and CD34 negativity, while one patient exhibited a high Ki-67 index (> 10%), which is a predictor of aggressive tumor behavior. None of the patients showed any recurrence in follow-up. We recommend performing complete endoscopic surgical excision to prevent recurrence. The use of DSA, preoperative embolization, and intraoperative use of the coblation technique provides a cleaner surgical field and reduced operating time.
RESUMEN
Retropharyngeal abscess (RPA) is a rare, potentially fatal condition found more frequently in young children usually who were having a history of Upper respiratory infection. RPA is an acute suppurative infection of the retropharyngeal space. In view of scarce literature availability and atypical presentation in infants, it poses a definitive diagnostic dilemma to the clinicians. Here, we are reporting a three-month-old male infant presented with feeding difficulty, obstructive sleep apnea and intermittent inspiratory stridor. Child was managed in a pediatric ICU with a multidisciplinary approach which involved pediatrician, otorhinolaryngologist pediatric anesthesiologist, microbiologist, and radiologist. With the recent advances, early radio imaging have a vital role in diagnosing the condition and also helps in planning of surgery. Prompt diagnosis and surgical management with appropriate antimicrobial therapy for this condition is imperative to prevent complications such as airway obstruction and mediastinitis. Timely surgical intervention, preferably intraoral transpharyngeal approach, to drain the abscess is recommended.
RESUMEN
COVID-19 infection during pregnancy is potentially dangerous to neonatal hearing, as it is the period of organogenesis, and associated hyperthermia may cause vascular damage, disruption of cell migration, and death of the dividing neuroblasts. To investigate the possible association between neonatal hearing loss and gestational mild COVID-19 infection. A prospective case-control study was conducted at a tertiary healthcare centre in North India from March 2020 to Oct 2022. Cases included the neonates born to COVID-19-positive mothers were subjected to hearing screening at 1, 3 and 6 months using otoacoustic emission (OAE) and automated auditory brainstem response (AABR). Similar protocol was applied to controls, i.e., neonates borne to mothers with no gestational history of COVID infection. Results were analyzed statistically. Our study reported that the statistical difference between groups A (n = 942) and B (n = 942) for gestational COVID-19 infection and neonatal hearing loss was insignificant at 1 month (p-value 0.272 for OAE and p-value 0.634 for AABR) and also insignificant at 3 and 6 months (p-value 0.679 for AABR, for both). The association between gestational mild COVID-19 infection during gestation and neonatal hearing loss is statistically insignificant at initial screening as well as sequential screenings.
