Comparative study in treatment of acne scars fractional carbon dioxide laser versus micro needling fractional radio frequency - A retrospective study.

Objectives: Efficacy of fractional carbon dioxide laser and microfractional radiofrequency in treatment of acne scars is well substantiated. The objective of this study was to compare the efficacy and safety of carbon dioxide laser versus microfractional radiofrequency in treatment of acne scars in skin type 3,4.

Material And Methods: Thirty-two patients of skin types 3-4 with grade 3 and 4 atrophic acne scars, of which 16 were treated with fractional carbon dioxide (CO) laser and 16 were treated with microfractional radiofrequency were retrospectively analyzed.

Appearance of intracranial cottonoids on intraoperative magnetic resonance imaging.

To our knowledge, this is a unique report of intraoperative magnetic resonance imaging (iMRI) of an intracranial cottonoid. The current literature describes images of cottonoids as a post-operative finding in the setting of an unintentionally retained foreign body; however, the iMRI images we present are important as the use of iMRI in the resection of complex tumors and epilepsy foci increases. This series of images was obtained during a craniotomy for tumor resection of a patient with dysembryoplastic neuroepithelial tumor.

Does subtotal resection ameliorate hypothalamic morbidity in pediatric craniopharyngioma? A 30-year retrospective cohort study.

Objective: The optimal extent of resection of craniopharyngiomas to minimize the long-term risks of hypothalamic and endocrine dysfunction (obesity and panhypopituitarism) in children remains uncertain. The purpose of this study was to report long-term outcomes of pediatric patients with craniopharyngioma undergoing surgical treatment and to study rates of endocrinological and hypothalamic dysfunction in association with extent of resection.

Methods: This retrospective study was performed in a cohort of children who underwent resection for craniopharyngioma at Children's of Alabama between 1990 and 2020.

Identification and targeting of a unique Na1.7 domain driving chronic pain.

Small molecules directly targeting the voltage-gated sodium channel (VGSC) Na1.7 have not been clinically successful. We reported that preventing the addition of a small ubiquitin-like modifier onto the Na1.

The natural product argentatin C attenuates postoperative pain via inhibition of voltage-gated sodium and T-type voltage-gated calcium channels.

Background And Purpose: Postoperative pain occurs in as many as 70% of surgeries performed worldwide. Postoperative pain management still relies on opioids despite their negative consequences, resulting in a public health crisis. Therefore, it is important to develop alternative therapies to treat chronic pain.
