RESUMO
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. Clinically, CSOM is thought to be a sequel of re-occurring episodes of Acute otitis media (AOM). Pseudomonas aeruginosa and Staphylococcus aureus are found to be the predominant pathogenic isolates in these patients. However, with the emergence of antibiotic resistance amongst these pathogens, the adequate evaluation and treatment of this condition has become more problematic. The disease has also been recognized as one of the neglected tropical clinical manifestations with high prevalence in school-age children, especially in poor or underprivileged countries. Moreover, untreated cases have further worsened the situation by contributing to various life-threatening complications. Thus, effective treatment and surgical strategies, as well as strengthening of hearing care algorithms along with the discovery of novel animal models for advanced clinical research, can jointly help to fight this disease. In this regard, mapping of the audiological analysis with microbiological findings in CSOM patients may help elucidate the frequency that favors growth of specific pathogens. Knowledge about this potential correlation can then support timely detection of the infection, which is perceived as one of the emerging approaches for its management. In addition to these strategies, creating a true sense of awareness among people can also help mitigate this pathological condition by facilitating early identification, prevention, and treatment. This review discusses the incidence, pathogenesis, investigations, complications, and available treatment modalities associated with CSOM.

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. The normative nasalance scores were compared for males and females in the control group. The nasalance scores of skeletal Class II and III subjects were compared to the combined normative scores of the control group. The NasalView was used for the objective assessment of nasalance. Oral syllables (/pa/and/pi/), nasal syllables (/ma/and/mi/), and 3 passages (Zoo passage, Rainbow passage, and Nasal sentences) were used to determine the nasalance scores. RESULTS: The intragroup comparison of nasalance scores in group 1 showed statistically significant differences for different stimuli. The gender-related comparison showed no statistically significant differences in nasalance scores. The intergroup comparison of nasalance scores for skeletal malocclusion showed no statistically significant differences for different stimuli except statistically significant lower nasalance values for nasal sentences in group 3 compared to the control group. CONCLUSION: The study concluded that the nasalance scores for nasal sentences in skeletal Class III malocclusion were significantly lower than in the control group and were not statistically significant between the 3 groups for all other stimuli.

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. The feeling of shame and stigma persists over time and affects the overall long-term survival of patients by deteriorating their quality of life. Objectives: Since shame and stigma is an important psychological domain of head and neck cancer, the present article aims toward evaluating the studies published so far for the assessment of shame and stigma in head and neck cancer and highlighting the lacunae in the existing research designs. The present study also aims to design a checklist that could be followed while developing, translating, or validating a psychometric instrument that aims to measure shame and stigma in head and neck cancer. Methods: In the present metanalysis, all articles published in the past years on shame and stigma in head and neck cancer was compiled using a predefined data extraction matrix. The available literature was compiled for major objectives of the study, the sample size used, major findings, and critical lacunae that need to be addressed. Results: Shame and stigma is a very important domain of psychological well-being in head and neck cancer patients, which yet not appropriately addressed and further need to be researched. Conclusion: Future studies could be based on the lacunae highlighted in the existing literature, and the prescribed methodology checklist could be taken into consideration while conducting further studies involving developing, translating, or validating a psychometric instrument related to shame and stigma in the head and neck cancer.
RESUMO
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. Methods: We have recruited 43 patients of oral cancer in the study who have a tumor in the buccal mucosa region. The Hindi version of the shame and stigma scale was used to analyse the shame and stigma in patients. The questionnaire was first provided to the patient for the self-administration and after that clinician administrated the questionnaire to the patient by keeping the clinician blinded to the patient self-administrated responses. Results: There was no significant difference in the global mean score and mean score of various subdomains of shame and stigma scale in the self-administered and clinician-administered mode of interview. However, the clinician-administered mode could provide more accurate measures as it helps the patient towards a better understanding of questions. Conclusion: It is recommended that the newly developed or translated self-reported measure should be tested for both patient administrated and clinician administrated compatibility. Questionnaires could be administrated by the clinician in the case when the patient is illiterate or in the case when the patient does not understand the language of the instrument.
RESUMO
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)). Proposed structures were unambiguously confirmed by synthesis followed by characterization using nuclear magnetic resonance spectroscopy (NMR), infrared spectroscopy (IR) and elemental analysis (EA). Based on the spectroscopic, spectrometric and elemental analysis data, the unknown impurities were characterized as 2-{1-[2-(2,3-dihydrobenzofuran-5-yl)-2-oxo-ethyl]-pyrrolidin-3-yl}-2,2-diphenylacetamide (Imp-A), 2-[1-(2-benzofuran-5-yl-ethyl)-pyrrolidin-3-yl]-2,2-diphenylacetamide (Imp-B), 2-{1-[2-(2,3-dihydrobenzofuran-5-yl)-ethyl]-1-oxy-pyrrolidin-3-yl}-2,2-diphenylacetamide (Imp-C) and 2-{1-[2-(7-bromo-2,3-dihydrobenzofuran-5-yl)-ethyl]-pyrrolidin-3-yl}-2,2-diphenylacetamide (Imp-D). Plausible mechanisms for the formation and control of these impurities have also been proposed. The method was validated as per regulatory guidelines to demonstrate specificity, sensitivity, linearity, precision, accuracy and the stability-indicating nature. Regression analysis showed a correlation coefficient value greater than 0.99 for darifenacin hydrobromide and its impurities. The accuracy of the method was established based on the recovery obtained between 86.6 and 106.7% for all impurities.

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. The novel coronavirus is a recently emerged zoonotic viral agent that affects the respiratory system of humans. Following its outbreak from the Wuhan city of China, the COVID-19 spreaded fiercely around the globe, forming a pandemic. Since COVID-19 is a contagious disease with no available treatment, social distancing is considered as the best strategy to prevent the geometric spread of infection. With the social distancing model, the head & neck cancer survivors along with the various other stakeholders perceived stigma being a high-risk group for COVID-19 infection. As the pool of caregivers is diminished due to pandemic, head & neck cancer survivors face increased social isolation and perceived stigma in asking for help from relatives. At the time of the pandemic, social support is critical to fighting against the disease. Social distancing should be maintained along with communication with the patients through calls, text, and online social platforms. It is not wise to stigmatize disease as, in that case, patients who are infected with the disease will try to hide it and avoid seeking medical care. With the promotion of social distancing, it is crucial to convey awareness regarding not to stigmatize the disease.
RESUMO
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. As a prevention strategy, awareness regarding the disease conveys to the mass population via media commercials. Media commercials which highlight the adverse outcomes of cancer are found to target the stigmatized perspective of disease. On the brighter side, more stigmatized is the patient image in the commercials, more motivation it will create in masses to avoid risk factors like tobacco, smoking and alcohol. But on the darker side, stigmatized commercials create a social environment in which people tend to maintain social distance to cancer patients, and patients have to bear social disapproval by society for their whole life. It reduces the self-esteem and quality of life of patients which affects their overall survival. In the present article, we review the status of stigma in head and neck cancer patients, tools that are available for assessment of stigma, and effects of the stigmatized media commercials on the patient's self-esteem. The present article represents the accurate picture of the problem and highlights the policies which could be employed to balance the paradox of stigmatized media commercials and a healthy social environment for cancer patients.
RESUMO
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. Apart from obesity, oral cancer is thought to have an inverse relation with neurodegenerative disorders presumably because cell death decreases in the former case and increases in the latter. Ancient mind-body techniques such as yoga have not been adequately tested as a tool to synergize the cellular equilibrium pertaining to the treatment of oral cancer. Nerve growth factor (NGF), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) are among the early experimental cellular biomarkers that may be used to probe the modulation of oral cancer, obesity, and neurodegenerative disorders. Yoga has been reported to influence these molecules in healthy individuals but whether their expression can be altered in patients of oral cancer by yoga intervention is the subject of this research being discussed in this review article. Therefore, the present article not only reviews the current status of research studies in oral cancer, obesity, and neurodegenerative disorders but also how these are linked to each other and why the investigations of the putative NGF pathway, involving TNF-α and IL-6, could provide useful clues to understand the molecular effects brought about by yoga intervention in such patients.
RESUMO
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. Group I received voice therapy and group II underwent thyroplasty type I and type IV. The voice was assessed pretreatment and 1 and 3 months posttreatment. Different parameters, such as habitual fundamental frequency (F0), signal-to-noise ratio, jitter, shimmer, maximum phonation duration, s/z ratio, and objective and subjective ratings of dysphonia, were analyzed. It was observed that in group I, all the parameters in seven out of ten patients improved significantly, except for shimmer. In group II, voice quality improved in 70% of the patients with all the parameters. As per previous studies, jitter and shimmer improved after a rehabilitation procedure. However, in this work, it is observed that shimmer did not improve in patients receiving voice therapy. The present study is the first of its type documenting and comparing the efficacy of voice therapy and thyroplasty type I and type IV in patients with UVFP.

RESUMO
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. Structural confirmation of this impurity was unambiguously carried out by synthesis followed by characterization using nuclear magnetic resonance (NMR), infrared spectroscopy (IR), mass spectrometry, elemental analysis (EA) and the impurity was confirmed as 2-[3,5-bis(2-hydroxy-phenyl)-[1,2,4]-triazol-1-yl]-benzoic acid (Imp-1). The newly developed method was validated according to ICH guidelines. The resolution between Imp-1 and deferasirox was found to be more than 6.0 and the detection limit of impurities was in the range of 0.0005-0.01%, indicating high selectivity and sensitivity of the newly developed method.
