Understanding the Impact of Skull Base Osteomyelitis: A Retrospective Analysis of 14 Cases.

Purpose Skull base osteomyelitis (SBO) or malignant otitis externa (MOE) is an invasive bacterial infection (a rarely fungal as well as potentially aggressive infection that involves the external auditory canal up to the temporal bone and skull base. This study provides insight into the various clinical presentations of skull base osteomyelitis, the effectiveness of different treatment approaches, and the overall prognosis of SBO based on our case series. Materials and methods This observational study comprises 14 SBO cases, including their diagnosis, follow-up, and treatment.

3D Virtual Reality Rehabilitation Therapy for Patients with Vertigo Due to Peripheral Vestibular Dysfunction.

This study aimed to evaluate 3D virtual reality rehabilitation therapy in patients with vertigo due to peripheral vestibular dysfunction. The subjects were 20 patients with peripheral vestibular dysfunction confirmed by Videonystagmography, Divided into 2 groups: Group 1 (study group) underwent vestibular rehabilitation therapy using 3D virtual reality in a customised VR lab with specific headset (Oculus rift and htc vive) with software application, which allows vestibular rehabilitation treatment using high quality immersive virtual reality console in which environment appears real and in 3D. The exercises are designed for gaze stability, increase postural stability, improve vertigo and daily activities, through sensory stimuli and in addition to conventional Cawthorne-Choksey exercises.

From symmetry breaking to symmetry swapping: is Kasha's rule violated in multibranched phenyleneethynylenes?

The phenomenon of excited-state symmetry breaking is often observed in multipolar molecular systems, significantly affecting their photophysical and charge separation behavior. As a result of this phenomenon, the electronic excitation is partially localized in one of the molecular branches. However, the intrinsic structural and electronic factors that regulate excited-state symmetry breaking in multibranched systems have hardly been investigated.

Identification of Crucial Intermediates in the Formation of Humins from Cellulose-Derived Platform Chemicals Under Brønsted Acid Catalyzed Reaction Conditions.

Humins are one of the undesirable products formed during the dehydration of sugars as well as the conversion of 5-hydroxymethylfurfural (HMF) to value-added products. Thus, reducing the formation of humins is an important strategy for improving the yield of the aforementioned reactions. Even after a plethora of studies, the mechanism of formation and the structure of humins are still elusive.

Influence of environmental factors on benthic nitrogen fixation and role of sulfur reducing diazotrophs in a eutrophic tropical estuary.

Benthic nitrogen fixation in the tropical estuaries plays a major role in marine nitrogen cycle, its contribution to nitrogen budget and players behind process is not well understood. The present study was estimated the benthic nitrogen fixation rate in a tropical estuary (Cochin) and also evaluated the contribution of various diazotrophic bacterial communities. Nitrogen fixation was detected throughout year (0.

Prevalence and distribution of Vibrio parahaemolyticus in finfish from Cochin (south India).

Finfish samples obtained from four retail outlets in Cochin between June 2009 and June 2010 were investigated for the occurrence of Vibrio parahaemolyticus. A total of 182 samples were collected and suspect isolates were identified using standard biochemical tests and were further confirmed by a species-specific tlh gene. V.
