Though conformal partial-brain irradiation is the standard adjuvant treatment for glioblastoma, there no consensus regarding optimal volume that needs to be irradiated. European Organisation Research and Treatment of Cancer (EORTC) The University Texas MD Anderson Center (MDACC) guidelines differ from Radiation Therapy Oncology Group (RTOG) in their approach toward peritumoral edema, whereas RTOG MDACC EORTC concept boost phase. A scarcity randomized comparisons has resulted remarkable...
Recognizing the high incidence of paranasal sinus mycoses in north India, we analysed retrospectively clinical, mycological and management aspects 178 patients with proven disease attending our institute. On basis radiological, histopathological findings, could be categorized into those allergic (8), non-invasive (92) invasive (78) types. Bony erosion without mucosal invasion by fungi was seen 16 disease. Young men from rural areas were most commonly affected. Rhinorrhoea nasal polyposis...
Abstract Background Although 2 studies totaling 11 cases have indicated some benefit of anti‐androgen treatment with flutamide on juvenile nasopharyngeal angiofibroma (JNA), it is not part contemporary practice. Methods Our approach was through a prospective, single‐arm, before‐and‐after study, in which 20 patients advanced JNA (Radkowski stage IIB–IIIB) were administered (per oral: 10 mg kg −1 day × 6 weeks) prior to surgical excision. Pretherapy and posttherapy tumor volume measurements...
Head-and-neck paragangliomas (HNP's) are rare autonomic neoplasms associated with high morbidity and mortality. We aimed to study epidemiology, clinicopathological correlation, management of HNP assist clinicians in advocating the most appropriate therapy.Epidemiological parameters, including age sex distribution, clinical presentation, tumor classification, familial predisposition, multicentricity, treatment modalities adopted, were analyzed this retrospective analysis 54 patients HNP.Age...
Background and Objectives The immune dysfunction in oral squamous cell carcinoma (OSCC) patients is one of the major factors for growth dissemination tumor affecting disease‐free survival. Methods phenotypic functional characteristics Regulatory T (T reg ) CD4 + CD25 FoxP3 subsets OSCC were assessed by multicolor flow cytometry its effector component (TGF‐β) Western blot qRT‐PCR. Results An increased ( P < 0.05) prevalence phenotypes (CD4 , CD8 was observed peripheral circulation that...
To evaluate the role of diffusion weighted imaging (DWI) and apparent coefficient (ADC) values at 3 Tesla in characterizing sinonasal masses.After ethical clearance, 79 treatment naive patients with head neck masses underwent magnetic resonance (MRI), including DWI using following b - 0, 500 1000 s/mm2. Thirty-one were found to have tumours subsequently analysed. Image analysis consisted a morphological evaluation conventional MR images, qualitative DW trace images quantitative assessment...
To test the toxicity and efficacy of concomitant boost radiotherapy alone against concurrent chemoradiation (conventional fractionation) in locally advanced oropharyngeal cancer our patient population.In this open-label, randomised trial, 216 patients with histologically proven Stage III-IVA were randomly assigned between June 2006 December 2010 to receive either (CRT) a dose 66 Gy 33 fractions over 6.5 weeks cisplatin (100 mg/m(2) on days 1, 22 43) or accelerated (CBRT) 67.5 40 5 weeks. The...
To comprehensively analyze the prognostic factors responsible for affecting outcomes following cochlear implantation in prelinguals.Retrospective cohort study from June 2004 to November 2015.Tertiary care center.Patients who had undergone during 2015 prelingual sensorineural hearing loss with a minimum follow-up of 2 years.Patients were evaluated presence 20 risk possibly influencing postimplantation using questionnaire.Assessment speech and auditory function was done at last intelligibility...
Malignant hilar biliary obstruction carries a poor prognosis, as the disease is often unresectable at time of diagnosis. Various palliative measures surgical/radiological/ endoscopic drainage with or without radiotherapy/chemotherapy have been tried dismal outcome. We prospectively studied effect unilateral metal stent intraluminal high dose rate (HDR) brachytherapy in patients type II malignant obstruction.Eight were treated contrast-free stenting followed by (ILBT). A retrospectively...
Abstract Prostate-specific membrane antigen (PSMA) is expressed in the endothelial cells of tumor-associated neovasculature various nonprostatic benign and malignant neoplasms including juvenile nasopharyngeal angiofibroma (JNA). Positive uptake on PET/CT imaging with 68 Ga-labeled PSMA noted a patient residual disease after initial surgery without any abnormal postoperative fibrosis, contrast to contrast-enhanced MRI, which was confirmed by biopsy. Ga-PSMA may be useful tool clinically for...
A spectrophotometric procedure for the simultaneous determination of mefenamic acid and paracetamol in a mixture is described. Using 0.01 M methanolic hydrochloric as solvent, absorbance measured at 248, 279 351 nm. The concentration each component can be calculated by solving two equations using wavelengths, either 248 nm or
Abstract Objectives: To analyse the aetiological profile and surgical results of patients with acquired chronic subglottic stenosis, formulate a scheme based on an audit various procedures. Methods: Thirty were treated by 65 procedures (31 endoscopic 34 external) between 2004 2009. Results: Isolated stenosis was noted as unusual in majority (27 cases), demonstrating contiguous tracheal or glottic involvement. The major aetiologies intubation injury ( n = 8) external 21) (i.e. blunt trauma,...
