Article Synopsis
  • The study examines the clinical and surgical management of aneurysmal bone cysts (ABCs) in the temporal bone, analyzing six case studies treated between 2017 and 2024 at a tertiary care institution.
  • Key findings indicate that the average patient age was 27.5 years, with symptoms like scalp swelling and hearing impairment, and successful surgeries resulted in no recurrences during a follow-up period.
  • The research concludes that complete surgical removal is the best treatment for temporal bone ABCs, stressing the importance of the tumor's stage and the extent of resection in determining patient outcomes.

Despite major advancements in our understanding of its fundamental causes, pain-both acute and chronic-remains a serious health concern. Various preclinical investigations utilizing diverse animal, cellular, and alternative models are required and frequently demanded by regulatory approval bodies to bridge the gap between the lab and the clinic. Investigating naturally occurring painful disorders can speed up medication development at the preclinical and clinical levels by illuminating molecular pathways.

Article Synopsis
  • Thoracic tracheal tumors are uncommon and can present challenges for surgery and anesthesia, making their management complex.
  • This study focuses on the percutaneous trans-tracheal endoscopic approach (PTTEA) as a minimally invasive alternative for patients with tracheal tumors when traditional methods fail.
  • Out of 16 patients treated from 2015 to 2022, most had successful outcomes with benign tumors, while malignant tumors required further treatment after initial procedures; PTTEA proved to offer advantages like better access and fewer complications.

Introduction: Head and neck malignancies are associated with poor prognosis and poor quality-of-life if detected late. Narrow-Band-Imaging(NBI) is one of the important tools, which helps in detecting these lesions earlier. By using narrow-wavelength(400-550 nm) it enhances the mucosal and submucosal vascularity against the pale mucosal background which helps us detecting benign, pre-malignant and malignant lesions.

Human epidermal growth factor receptor-2 (HER2)-positive breast cancer metastasis remains the primary cause of mortality among women globally. Targeted therapies have revolutionized treatment efficacy, with Trastuzumab (Trast), a monoclonal antibody, targeting HER2-positive advanced breast cancer. The tumor-homing peptide iRGD enhances the intratumoral accumulation and penetration of therapeutic agents.

Article Synopsis
  • The study focuses on understanding the causes and effects of invasive fungal rhinosinusitis that impacts the skull base, examining data from 79 patients over a 5-year period at a specialized hospital.
  • Key findings revealed that a significant portion (65.8%) of cases involved skull base rhino-orbitocerebral mucormycosis (ROCM), with a notable overlap with COVID-19 and diabetes mellitus among affected patients.
  • The research highlights that the pterygopalatine fossa was the most commonly affected area, with important neurovascular structures like the pterygopalatine ganglion also frequently involved, stressing the importance of monitoring invasive fungal infections post-COVID-19.

Dengue fever is a viral infection transmitted by the bites of female mosquitoes. Repeat infections with different viral serotypes are possible, with an increased risk of severe dengue. Dengue hemorrhagic fever is one of the most severe presentations of dengue, with thrombocytopenia, increased capillary permeability with resultant rash, and an increased risk of spontaneous bleeding.

This paper outlines a methodical approach for isolating 6-gingerol (1a) from rhizomes on a gram-scale, resulting in a product of high purity and significant yield. Further, 6-gingerol (1a) [SSG1] derivatives, including 1-(4-hydroxy-3-methoxyphenyl)decane-3,5-dione (1ab), were synthesized via a semi-synthetic pathway involving DMP-mediated fast oxidation and replication. Subsequently, a new series of 1,4-benzodiazepines (3a-c) was synthesized quantitatively using a basic technique.

This study describes the clinical profile, operative findings, surgical technique, type of implant and complications encountered in implantation of abnormal cochlea by the transcanal (veria) technique in a tertiary care centre. This is a retrospective study done amongst 337 patients who underwent cochlear implantation by veria technique between January 2013 to August 2023. Based on pre-operative imaging with high-resolution computed tomography and magnetic resonance imaging the cochleovestibular malformations in this study were classified according to Sennaroglu classification and the cochlear ossification was graded from I to IV.

Pulsatile tinnitus (PT) is the perception of an auditory sensation without an external source and in synchrony with the heartbeat. One of the most common cases of PT is bony anomalies of the sigmoid sinus, including dehiscence or diverticula. This case report describes a 26-year-old female patient who presented with pulsatile tinnitus caused by sigmoid sinus diverticula and dehiscence, which was successfully treated with cortical mastoidectomy with diverticula closure using pedicled temporalis fascia and resurfacing of the dehiscence with autogenous bone pate along with bone cement.

Multiple post-receptor intracellular alterations such as impaired glucose transfer, glucose phosphorylation, decreased glucose oxidation, and glycogen production contribute to insulin resistance (IR) in skeletal muscle, manifested by diminished insulin-stimulated glucose uptake. Type-2 diabetes mellites (T2DM) has caused by IR, which is also seen in obese patients and those with metabolic syndrome. The Vitamin-D receptor (VDR) and poly unsaturated fatty acids (PUFAs) roles in skeletal muscle growth, shapes, and function for combating type-2 diabetes have been clarified throughout this research.

Tamanu oil has traditionally been used to treat various skin problems. The oil has wound-healing and skin-regenerating capabilities and encourages the growth of new skin cells, all of which are helpful for fading scars and hyperpigmentation, as well as promoting an all-around glow. The strong nutty odor and high viscosity are the major disadvantages associated with its application.

Objective: Geriatric populations are most at risk for the tuberculosis pandemic, and as people age, the rate of infection rises steadily and drastically. Geriatric individuals frequently experience diagnostic challenges with a wide range of comorbidities, but employing all available standard and novel methods to diagnose any infection is crucial. The prophylactic and therapeutic management for the geriatric population presents a significant difficulty and challenge in assessing an appropriate and effective therapeutic outcome due to prolonged drug therapy and adverse drug reactions.
