Background: Surgical excision of the tumor remains the primary choice for the treatment of head and neck cancer patients, but it often leads to facial disfigurement, which further causes mutilation in the patients. Mutilation causes shame and stigma, which imparts significant psychological strain on patients, and tends to impair their quality of life.

Objective: The present study aimed to assess the shame and stigma over long-term postoperative survival duration in head and neck cancer patients.

Background: Head and neck cancer is the most common cancer around the globe, following lung cancer and breast cancer. Treatment at advanced stages of head and neck cancer is usually followed intense surgical procedures, which leads to mutilation among patients. Mutilation imparts a sense of disgrace and causes a feeling of shame and stigma in the patient.

Background: Self-reported measures are the questionnaire-based instrument that are routinely used in the clinical scenario to assess psychological health. Technically, the self-reported measure should be administrated by the patients themselves but due to the complexity of tools and illiteracy among patients, clinicians often tend to interview the patients.

Objective: Present article aims to compare the accuracy of a self-reported measure in the assessment of the psychological health of a patient when the instrument is self-administrated by the patient and when administrated by the clinician or researcher.

Cancer in the head and neck region is among the most common cancer around the world, the incidence of which keep increasing in past years. Treatment of disease is usually done by the surgical excision which often leads to some degree of facial disfigurements which cause mutilation in patients. Mutilation imparts the feeling of stigma in patients, and patients usually tend to hide facial disfigurements using additional clothing.

Otitis media (OM) is an umbrella term for a number of conditions associated with middle ear inflammation. Chronic suppurative otitis media (CSOM), a type of OM, is characterized by long-term middle ear infection with perforated ear drum and otorrhea. The most common outcome associated with it is acquired hearing impairment in infected individuals which ultimately affects their cognitive and scholastic developments.

Objective: The objective of this study is quantitative assessment of nasalance for skeletal Class I (normative values), Class II, and III malocclusion in the English language for the North Indian population and to compare the normative values with the nasalance scores obtained from individuals with skeletal Class II and III malocclusion and to evaluate the normative values as a function of gender.

Material And Methods: The study was conducted on a total sample of 200 patients with 100, 50, and 50 in group 1 (control group, Skeletal Class I), group 2 (Skeletal Class II), and group 3 (Skeletal Class III), respectively. ANB angle (anteroposterior angle formed by point A, nasion, and point B) measured on lateral cephalogram was used to categorize the patients into 3 groups.

Social stigma is the spoilation of the social image of an individual, which leads to the social disapproval of the individual by the community. Patients of many diseases like HIV, deafness, and reproductive disorders often face social disproval. Head & neck cancer survivors perceived stigma due to the mutilation that occurred after surgical treatment procedures.

Despite tremendous advancements in medicine, the number of oral cancer cases continues to increase, and the need for integrating alternate medicine or adopting an integrative approach has become a compelling cost-effective requirement for the management and treatment of diseases. Conventional treatment of oral cancer involves surgery followed by radiotherapy with or without chemotherapy which causes several complications including poor quality of life and high chances of recurrence of cancer. Oral cancer is often linked with obesity which is major risk factors in other cancers.

In this work, a study on the efficacy of different therapeutic modalities in patients with unilateral vocal fold paralysis (UVFP) was carried out. The study included 20 patients with UVFP, divided into two groups. The objective of this work is to evaluate the voice quality in these patients and to compare the voice following surgery and voice therapy.

A new impurity was detected during high performance liquid chromatographic (HPLC) analysis of eslicarbazepine acetate active pharmaceutical ingredient. The structure of unknown impurity was postulated based on liquid chromatography mass spectrometry using electrospray ionization and ion trap analyzer (LC/ESI-IT/MS) analysis. Proposed structure of impurity was unambiguously confirmed by synthesis followed by characterization using H, C nuclear magnetic resonance spectrometry (NMR), H-H correlation spectroscopy (COSY) and infrared spectroscopy (IR).

The present study describes the identification and characterization of two process impurities and major stress degradants in darifenacin hydrobromide using high performance liquid chromatography (HPLC) analysis. Forced degradation studies confirmed that the drug substance was stable under acidic, alkaline, aqueous hydrolysis, thermal and photolytic conditions and susceptible only to oxidative degradation. Impurities were identified using liquid chromatography coupled with ion trap mass spectrometry (LC-MS/MS(n)).

An unknown impurity was detected in deferasirox drug substance by a newly developed high performance liquid chromatography (HPLC) method. The unknown impurity was identified by liquid chromatography-tandem mass spectrometry using electrospray ionization source and Q-trap mass analyzer (LC-ESI-QT/MS/MS). Based on LC-MS/MS data and knowledge of the synthetic scheme of deferasirox, this impurity was proposed as the regio-isomer of deferasirox.

The patient was admitted after reporting a snake bite from which he later developed neurological signs and symptoms among which a flaccid dysarthria. The patient underwent speech therapy and showed significant improvement over a short period of time. The favorable outcome of the present study highlights the role of speech therapy in such a case, where it often remains un-emphasized.

Background: Thalassemia is a hereditary disorder requiring regular blood transfusion.

Purpose: To determine hearing sensitivity in transfusion-dependent thalassemics who were receiving desferioximine and on oral iron chelation (desferioximine) therapy.

Methods: 26 patients with B-thelassemia in the age range of 5-22 years were enrolled in the thalassemia transfusion unit in the Advanced Pediatric Center of Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India.
