The Role of Biofilms in Chronic Otitis Media-Active Squamosal Disease: An Evaluative Study.

OBJECTIVES: To study the presence of biofilms in patients of chronic otitis media (COM)-active squamosal disease and to evaluate the microflora and clinical impact of biofilms. METHODS: A total of 35 patients suffering from COM - active squamosal disease was studied. Cholesteatoma sample was collected at the time of mastoid surgery and the same was used to image for biofilms by scanning electron microscope. The said sample was also analyzed microbiologically. RESULTS: Biofilms were present in 25 (72%) patients including 6 cases of fungal biofilms (24%). Biofilms were detected irrespective of the micro-organism growth. No statistically significant relationship was observed between biofilms and discharging ear and complications of COM. Though univariate analysis of our data found some correlation between duration of disease, the extent of cholesteatoma and ossicular necrosis but multivariate analysis revealed no such associations, thereby implying a doubtful association between these factors and biofilm. CONCLUSIONS: Biofilms are an integral part of cholesteatoma ear disease and sometimes harbors fungal isolates.

Can Pregnancy Lead to Changes in Hearing Threshold?

PURPOSE: This study explores the changes in hearing thresholds in pregnancy. MATERIALS AND METHODS: A prospective hospital-based observational study was performed with a total of 69 patients in the age-group of 18 to 40 years. Patients underwent hearing assessment twice during the study period. Conventional pure tone audiometry and impedance audiometry were performed, first during the antepartum period (28-32 weeks of gestational age) and second time during the postpartum period (6 weeks postpartum). RESULTS: Significant difference was seen between the average of air conduction threshold values at speech frequencies when antepartum values were compared with postpartum values. CONCLUSION: The alterations in hearing sensitivity in pregnant females which improved during the postpartum period can be attributed to pregnancy.

The role of sinus CT in surgical treatment decisions for chronic rhinosinusitis.

AIMS & OBJECTIVES: To define a predictive role of Lund Mackay CT scan [LM] score in treatment of chronic rhinosinusitis [CRS] by functional endoscopic sinus surgery [FESS]. MATERIALS & METHODS: A prospective study was done on the cited subject in a sample size of 30 patients suffering from CRS failing maximal medical treatment. All the patients underwent FESS under general anaesthesia. CT scan with Lund Mackey scoring was done preoperatively and postoperatively. The symptomatic improvement was analysed using SNOT-22 score over a time period of one year. The SNOT-22 scores were statistically analysed with pre-op Lund Mackey scores to draw judicious conclusions. RESULTS: A mean Lund Mackey pre-operative score [LM] of 13.1 was recorded in the patients undergoing FESS for CRS. Further, the patients were divided into two groups: one with LM score less than 13.1 [Group-A] and the other with LM score of more than 13.1 [Group B]. A statistically significant improvement in symptoms with good long-term prognosis was recorded in Group-B only. In addition, a direct correlation between Lund Mackay score and extent of surgery was also seen, greater the score more extensive the FESS. CONCLUSION: There is a predictive value of LM score in prognosis of FESS. We believe that a minimum LM score of 13.1 gives good clinical outcomes in patients with CRS who undergo FESS and thus can be used as a threshold for recruiting CRS patients for FESS.

Circumferential Subannular Tympanoplasty: Panacea for revision tympanoplasty.

OBJECTIVE: To evaluate the role of Circumferential Subannular Tympanoplasty [CST] in cases of Revision tympanoplasty. METHODS: A retrospective statistical analysis of data of 81 patients who underwent revision tympanoplasty with CST technique [essentially Type I tympanoplasty] was done. An intact graft at the end of 6 months was regarded as a surgical success. RESULTS: Overall, we recorded a surgical success rate of 97.5% [79 out of 81 cases] with a 100% surgical success for anterior perforations. There was no impact of size or site of perforation on the outcomes of revision tympanoplasty by this technique. In addition, a statistically significant hearing improvement was recorded in the study. The mean pre-operative and post-operative ABG were 33.85 dB and 18.87 dB respectively. The mean ABG closure was 14.89 dB. The value of "p" by Chi square test was found to <.05. CONCLUSION: CST is an excellent technique for revision tympanoplasty and seems to address the shortcomings of conventional onlay and inlay techniques.

Rhabdomyosarcoma: Nose Presenting As Second Primary with Carcinoma Tongue.

INTRODUCTION: Presence of two primary malignancies is rare and occurs in 3-5% of the cancer patients. As per our extensive internet research, this is the only reported case of a synchronous sino-nasal embryonal rhabdomyosarcoma with squamous cell carcinoma-tongue. The case report is important because of the rare diagnosis and the challenge we faced in the diagnosis and treatment of the patient because of the paucity of literature available on management adult rhabdomyosarcoma. CASE REPORT: We present a very rare case of an adult male with a sino-nasal mass diagnosed to be an embryonal type rhabdomyosarcoma. The patient also had a moderately differentiated squamous cell carcinoma-tongue for the past 8 months. Radiological investigations were done to see the extent of the sino-nasal mass and the extent of tongue lesion, which was seen to be involving the base of the tongue. The patient was referred for chemoradiotherapy but succumbed to the disease after 2 weeks of treatment. CONCLUSION: Occurrence of rhabdomyosarcoma in synchronous malignancies is extremely rare as the most common first as well as second primary malignancy in a diagnosed case of head and neck cancer is squamous cell carcinoma. A multidisciplinary approach to the treatment of adult rhabdomyosarcoma has been recommended. The combined use of chemoradiotherapy and surgery has improved treatment in the recent past but RMS in adults is still a rare head and neck tumour that carries a poor prognosis despite aggressive therapy.
