Recurrent respiratory epithelial adenomatoid hamartoma of the nasal cavity.

Respiratory epithelial adenomatoid hamartoma (REAH) refers to a rare entity characterized by excessive proliferation of the normal glandular elements of the respiratory epithelium present as mass lesions in various body sites. The pathophysiology of the disorder is still debated. The condition can closely mimic inverted papilloma, adenocarcinoma, and nasal polyposis clinically, radiologically, and pathologically. However, distinction from the above disorders is important in view of the excellent prognosis associated with complete excision of REAH. Recurrence is uncommon with complete excision, and a high-risk pathologic transformation is not expected with this lesion. We report a case of recurrent REAH managed with repeat surgical endoscopic excision. The patient is disease free 4 years after re-excision of the lesion.

Head and neck involvement with histoplasmosis; the great masquerader.

INTRODUCTION: Head and neck involvement with histoplasmosis usually occurs as a part of the disseminated illness. There are no pathognomic features of the upper aerodigestive tract involvement and the lesion may mimic a host of other conditions. The current report presents our experience with head and neck histoplasmosis in a non-endemic tertiary care center. MATERIALS AND METHODS: We present a case of disseminated histoplasmosis with oral symptoms and lesions as the chief complaints. A 10 years' retrospective institutional database search was undertaken to identify the patients with histoplasmosis affecting head and neck region treated at our institution. The demographic and treatment details of the patients were reviewed. RESULTS: In addition to the index patient, four more patients (two with gingivobuccal and one each with nasal and laryngeal histoplasmosis) were found. Out of the five patients, only one patient was found to have underlying immunosuppression. All of the patients were diagnosed with biopsy showing typical appearance of the intracellular organism. All the patients were satisfactorily treated with systemic antifungal treatment. CONCLUSION: Upper aerodigestive tract involvement with histoplasmosis can present as an intriguing clinical puzzle. A high index of suspicion is needed and biopsy is the gold standard for the diagnosis. Intravenous Liposomal Amphotericin B and oral Itraconazole are standard treatment agents of choice and are highly efficacious in achieving cure.

Bullet in tracheobronchial tree without lung contusion removed by fibreoptic bronchoscopy in two parts.

A person presented with multiple gunshot injury. Chest x-ray & CT whole body trauma protocol was done which showed multiples pellets of bullet in abdomen and one bullet in elbow according to entry wound. There was an entry wound without any bullet in left maxillofacial region however there was no exit wound. A bullet was noticed in tracheobronchial tree. There was no pneumothorax any signs of chest trauma or any pneumomediastinum. It is assumed that the bullet first hit the left cheek (maxilla) and lost its momentum. As the patient lost consciousness and had a fall leading to inhalation (aspiration) of bullet in the airway. As per ballistic experts it was basically a jacketed metallic bullet. As bullet moved in airway, the outer metallic core reached the trachea near carina and the soft metallic core slipped more distally to right main bronchus and bronchus intermedius. While inspection the outer metallic capsule was seen in trachea just above carina which was hollow and was gently removed with the help of foreign body forceps. The core was removed with dormia basket without any mucosal tear. The favorable outcome can be attributed as patient had no lung contusion or chest trauma and bullet was inhaled which was not very old. The evolution of bronchoscopy started with rigid one but the fibreoptic bronchoscopy (FOB) has revolutionized the pulmonary interventions. The FOB can be used with minimal traumas under local anesthesia resulting in markedly reduced morbidity and mortality.

Submandibular Duct Re-routing for Drooling in Neurologically Impaired Children.

Drooling is a challenging situation to manage especially in neurologically impaired pediatric population. Numerous surgical procedures have been described in literature but none of them is standardized. We evaluate the effectiveness of bilateral submandibular duct rerouting and sublingual gland excision in drooling paediatric patients. Prospective interventional study was conducted from November 2007 to September 2009 in twenty-eight pediatric patients with drooling who had failed conservative treatment modalities. Patients underwent bilateral submandibular duct transposition and sublingual gland excision. Patients were assessed pre-operatively, at 7, 30 and 90 days after surgery for drooling severity, frequency as per Thomas-Stonell and Greenberg classification and also number of bibs changed per day. Result was categorized using Wilkie and Brody criteria for assessing effectiveness of the surgery. Twenty-eight patients were successfully operated. All patients were followed-up for a duration of at least 3 months. The success rate achieved in term of control of drooling was 95.2 % at 3 months follow up. Statistically significant difference (p < 0.001) was noted in pre-operative and postoperative mean values for severity and frequency of drooling and also bibs/day. Transient, minor complications (n = 5/28, 17.8 %) were encountered following this surgical procedure. Bilateral submandibular duct rerouting and sublingual gland excision in drooling paediatric patients is a simple and effective surgery with minor operative morbidity. Concomitant sublingual gland excision bilaterally helps in reducing the incidence of ranula formation significantly.

A study of voice profiles and acoustic signs in patients with Parkinson's disease in North India.

We aimed to study the voice profiles of patients with Parkinson's disease (PD) and correlate the profiles with disease severity. A total of 133 patients with PD were recruited. Patients were divided into two groups: Group 1 with a Unified Parkinson's Disease Rating Scale (UPDRS) score of ≤45; and Group 2 with a UPDRS >45. Speech was analyzed using the Indian Speech and Hearing Association (ISHA) articulation assessment and Vaghmi software. A total of 87 patients (65.41%) reported a history of speech problems. Examination revealed slow reading speed (64.7% of patients), hoarseness of voice (60.2%), articulatory defect (39.8%) and jerky speech (32.3%) as common abnormalities. Misarticulation was most often observed among the labial (42.1%), followed by lingual and palatal syllables. The ISHA articulation test demonstrated significant differences in mean numbers of words distorted (p<0.001) and intelligible speech (p=0.004) between patients with early and advanced PD. Vaghmi software analysis (Speech and Voice Systems, Bangalore, India) also revealed significant difference between the two groups in maximum phonation duration (p=0.034), inability to phonate (noiseless speech, Z; p=0.002) and the mean noise-to-noiseless speech (S/Z) ratio (p=0.006).

Changes in ventilatory function following surgery for bilateral abductor paralysis.

Management of bilateral vocal fold immobility continues to remain a challenge for the Otolaryngologist who attempts to create a balance between creation of an adequate airway and preservation of voice. The flow volume loop obtained by spirometry provides an ideal objective assessment tool to evaluate the results of surgery for this condition. Our experience in using peak inspiratory flow rate (PIFR) and forced inspiratory flow with 50% of vital capacity (FIF(50)) in the lung in assessing the results of surgery is described. Seventeen patients were included in the study. The surgical procedures performed included laser posterior cordectomy with partial arytenoidectomy, endoscopic arytenoidectomy and posterior cordectomy-Kashima's technique. Twelve out of 17 patients were successfully decannulated, a success rate of 70.6%. All patients except one showed an increase in mid-inspiratory flow rates and peak inspiratory flow rates. The mean increase in FIF(50) was 0.44 l/sec (52.6%) and the mean increase in PIFR was 0.41l/sec (39.77%). No statistically significant difference in improvement of inspiratory flow rates was observed between the three surgical procedures used in the study.

Post traumatic psuedoaneurysm of the lingual artery.

Post traumatic pseudoaneurysm is a well documented complication of vascular injuries which needs early diagnosis and early management otherwise there may be significant morbidity and mortality. We present a patient who had been operated elsewhere for a foreign body lodged in neck during splinter injury sustained while bursting a cracker. He presented to ENT department of our hospital with bleeding from the wound site. We are reporting this case because pseudoaneurysm of the lingual artery as such is very rare. We could not find any other reported case in available English literature. Moreover the treating ENT surgeons need to be sensitized to the presence of such an entity and hence avoid late complications.

A technique for the orientation of endoscopically resected laryngeal lesions.

Endoscopic resection is a widely accepted method of treating early laryngeal malignancies. Accurate histological assessment of resected laryngeal specimens can be difficult due to their small size and potential damage and distortion caused by standard orientation and processing techniques. A new technique is described which employs dehydrated cucumber to mount laryngeal specimens for orientation and processing. This technique is quick, easy, cheap and reliable, allowing accurate histological assessment of potentially malignant lesions. Better orientating and processing of laryngeal specimens can optimise treatment decisions based on histological results.

Unilateral pseudohypacusis in children.

Pseudohypacusis is a condition where there is hearing loss without any organic etiology. Though this condition has been reported long before, the literature exists mainly in the form of case reports. An interesting aspect of pseudohypacusis is of patients presenting with unilateral pseudohypacusis. In children, there often exist underlying psychological factors related to the occurrence of this condition. This condition is usually suspected when there is discrepancy in audiometric testing. The authors hereby report a child of unilateral pseudohypacusis presenting with psychological stressors, along with an overview of the management of such conditions.

Management protocols of Allergic Fungal Sinusitis.

Controversy surrounds the appropriate surgical approach and the appropriate medical therapy for Allergic Fungal Sinusitis. The present prospective study aims to assess the impact of these factors on the treatment outcome of Allergic Fungal Sinusitis. In the present study 34 cases with AFS were randomized into one of 3 methods of post operative therapy i.e. systemic itraconazole (group A, n=11), topical steroids (group B, n=12) and nasal alkaline douches only (group C, n=11). Outcome was assessed at 6 months post-operative by the Kupferberg grading system for assessment of nasal and sinus mucosa. Grade '3' mucosal disease was defined as recurrence.Complete pre-operative opacification of sphenoid and frontal sinus was a predictor of poorer outcome. Postoperative systemic itraconazole therapy demonstrated a trend towards a better outcome but was not statistically significant. Larger trials are required to conclusively evaluate the merit of various post-operative treatment regimens for AFS.

Validation of the modified Berlin questionnaire to identify patients at risk for the obstructive sleep apnoea syndrome.

BACKGROUND & OBJECTIVES: Awareness regarding obstructive sleep apnoea (OSA) among general public as well as practicing physicians is low in India. The present study was undertaken to test the utility of modified Berlin questionnaire for risk categorization of OSA in Indian setting. METHODS: The modified Berlin questionnaire was administered in 180 middle aged adults (of 320 screened), of whom, 104 underwent overnight polysomnograhy, in a cross-sectional study at a tertiary care, referral center in north India. Questionnaire addressed the presence of frequency of snoring, wake time sleepiness, fatigue, obesity and hypertension. Subjects with persistent and frequent symptoms in any two of these three domains were considered in high risk category for obstructive sleep apnoea. Overnight polysomnograhy was performed to measure apnoea and hypopnoea index (AHI). RESULTS: Questions about the symptoms demonstrated internal consistency (Cronbach alpha correlations 0.92-0.96). Of the 180 respondents to the screening questions, 80 were in the high risk and the rest were in low risk group. For 104 subjects who underwent polysomnograhy, risk grouping was useful in prediction of AHI. High risk category predicted an AHI >5 with a sensitivity of 86 per cent, specificity of 95 per cent, positive and negative predictive values of 96 and 82 per cent respectively. These results were comparable to Berlin questionnaire study done in the western population for validation. INTERPRETATION & CONCLUSION: On the basis of the findings of present study it is concluded that administration of modified Berlin questionnaire prior to a polysomnography study can identify high risk subjects and can thus avoid unnecessary polysomnography studies especially in resource-limited settings. To identify subjects at risk for OSA syndrome in general population, this questionnaire can be applied. However, the findings of the present study need to be confirmed further in a large number of subjects in a community-based setting.

Prediction of obstructive sleep apnea in patients presenting to a tertiary care center.

The objective of this prospective observational clinical study is to derive and validate a diagnostic model for prediction of obstructive sleep apnea (OSA) in subjects presenting with non-sleep-related complaints in a tertiary care center in north India. We included 102 subjects (group I, range 31-70 years) presenting to the hospital with non-sleep-related complaints. None of the subjects had any significant comorbid illness such as respiratory or congestive cardiac failure. All subjects underwent detailed evaluation including polysomnography (PSG). Various parameters were compared between the cases (apnea-hypopnea index, AHI > or =15/h) and controls (AHI <15/h). Using multivariate logistic regression analysis, a diagnostic model for prediction of OSA was derived. Subsequently, using similar selection criteria, 104 subjects (group II, range 32-68 years) were included for validation of the newly derived diagnostic model. Body mass index [BMI; OR (95% CI), 1.14(1.1-1.2)], male gender 5.0(1.4-27.1), relative-reported snoring index (SI) 2.8(1.7-5.0), and choking index (ChI) 8.1(1.4-46.5) were significant, independent predictors of OSA. Diagnostic model was computed as score = [1.61 x (gender)] + [1.01 x (S1)] + [2.09 x (ChI)] + [0.1 x (BMI)] where, gender: 0 = female, 1 = male and SI, ChI, BMI are actual values. The diagnostic model had an area under the receiver operator characteristics curve of 89.6%. A cutoff of 4.3 for the score was associated with sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 91.3, 68.5, 70.5, and 92.3%, respectively. Misclassification rate with the application of the diagnostic model on group II subjects was 13.5% (14/104). Sensitivity, specificity, PPV, and NPV of the model for predicting OSA in this group were 82, 90.7, 89.1, and 84.5%, respectively. BMI, male gender, SI, and ChI are independent predictors of OSA. Diagnostic model derived from these parameters is useful for predicting presence of OSA and screening subjects for PSG.

Thyroxine replacement therapy reverses sleep-disordered breathing in patients with primary hypothyroidism.

BACKGROUND AND PURPOSE: Anecdotal reports suggest that sleep-disordered breathing (SDB) is common among patients with primary hypothyroidism. This study was undertaken to determine the prevalence of SDB and to evaluate the effect of thyroxine replacement therapy on SDB in patients with primary hypothyroidism. PATIENTS AND METHODS: Fifty consecutive newly diagnosed, untreated symptomatic patients with primary hypothyroidism (age: 34+/-11 years; males: 21 [42%]) were prospectively studied. Physical examination, anthropometry, fasting blood glucose and serum lipids were performed in all patients at baseline. Polysomnography was done at baseline in all patients and was repeated after adequate thyroxine replacement in those who had SDB. RESULTS: SDB defined as apnea-hypopnea index (AHI) > or =5 was present in 15 patients (30%) at baseline and was reversible in 10 of the 12 patients evaluated following thyroxine replacement therapy (P=0.006). Thyroxine replacement therapy was associated with improvement in findings that reflect a compromised upper airway, such as macroglossia (4 [33%] vs. 1 [8%]; P=0.083), myoedema (5 [42%] vs. 1 [8%]; P=0.046) and facial puffiness (10 [83%] vs. 1 [8%]; P=0.003). CONCLUSIONS: Reversible SDB is common among patients with primary hypothyroidism. Changes in upper airway anatomy resulting from hypothyroidism probably contribute to the development of SDB in these patients.

Laryngopharyngeal reflux: Current opinion.

The increasing importance of LPR is being recognized day by day in ENT practice. LPR has a significant negative impact in the quality of lives of the patients. Although its impact is similar in some respects to that of laryngopharyngeal disease, LPR has a more significant impact on patient's social functioning and vitality.([23]) All ear, nose and throat practitioners need to be sensitised to the presence of LPR and the need for starting treatment wherever required. Lot of hitherto symptoms of unknown aetiology are being increasingly of treating patients with atypical reflux symptoms such as hoarseness (unexplained cause), globus, throat clearing, cough, etc., with antireflux therapy.([24]).

A stepped approach for prediction of obstructive sleep apnea in overtly asymptomatic obese subjects: a hospital based study.

BACKGROUND AND PURPOSE: Prevalence of obstructive sleep apnea (OSA) is high in obese subjects, many of whom may not be overtly symptomatic. Polysomnography (PSG) is a costly and time-consuming investigation. Since it is not feasible to subject all obese individuals to PSG, it is useful to define predictors of OSA among these subjects. PATIENTS AND METHODS: One hundred and eighteen obese subjects [body mass index (BMI)> or =25 kg/m(2)] presenting to the hospital with non-sleep related complaints were included, of which 53 subjects with PSG evidence of OSA [apnea-hypopnea index (AHI)> or =15/h] were defined as cases and 65 subjects without any evidence of OSA (AHI<15/h) were defined as controls. Anthropometry, biochemical investigations, blood gas analysis, pulmonary function tests, and PSG were performed for all subjects. RESULTS: Waist hip ratio (WHR) (as percentage of a standard) [odds ratio (95% CI): 1.07 (1.00-1.14); P = 0.049] male gender [odds ratio (95% CI): 3.97 (0.99-15.81); P = 0.046] and neck circumference (NC) [odds ratio (95% CI): 1.23 (1.03-1.47); P = 0.023] were found to be independent predictors of OSA. Overnight oxygen desaturation data were evaluated in patients selected as having OSA on the basis of these clinical markers, and the best cut-off for level of desaturation (10%) was defined. The stepped approach had a specificity, sensitivity, positive and negative predictive value of 89.2, 88.5, 86.8 and 90.6%, respectively, for the diagnosis of OSA. CONCLUSIONS: Male gender, WHR and NC are independent predictors of OSA in overtly asymptomatic obese subjects. A stepped approach to diagnose OSA should be used, as it is accurate and cost-effective.

Sleep disordered breathing in chronic obstructive pulmonary disease.

We prospectively studied sleep disordered breathing in 50 consecutive patients (39 males) with chronic obstructive pulmonary disease (COPD) with chronic respiratory failure (CRF) (n=33) and without CRF (n=17) by performing polysomnography. Patients with CRF had a lower mean nocturnal oxygen saturation (SaO2 %) (88.6+/-6.7 vs. 96.3+/-0.8; p=0.0001) and a lower minimal nocturnal SaO2 (73.6+/-12.0 vs. 84.3+/-7.3; p=0.002) compared to those without CRF, suggesting that patients with CRF tend to have more severe drops in nocturnal SaO2. Patients with CRF also had a lower FEV1 (% predicted) (p=0.01) and PEFR (% predicted) (p=0.031) compared to those without CRF suggesting an indirect relation to the oxygen saturation. Other pulmonary functions were comparable between both the groups. Among patients with and without CRF, the total sleep time (minutes); the rapid eye movement (REM) stage (% of total sleep time); the non-rapid eye movement (NREM) stage (% of total sleep time) were comparable (p=NS). Only three of the 50 patients with COPD had a significant (>5) apnea-hypopnea index (AHI) (total no. of apneas + total no. of hypopneas/ total sleep time [(hours) = AHI] and these three patients had a mean BMI = 27.7 which was higher than the mean BMI of the whole group (21.1). The AHI was comparable in patients with and without respiratory failure. Multiple regression analysis revealed a positive correlation between AHI and the neck circumference (r=0.41; p=0.005) and BMI (r=0.31; p=NS). There was a small but statistically insignificant negative correlation between AHI and neck length (r= -0.28; p=NS). We conclude that, BMI per se contributes to the AHI and nocturnal desaturation in patients with COPD.

Fire during the use of Nd-Yag laser.

Fire during the use of Nd-Yag laser is a very rare complication. A case report of laser fire during the use of Nd-Yag laser for congenital subglottic stenosis is reported. The probable causes for the fire, management and short review of literature are dealt with. This case report highlights the importance of following the safety protocol during laser surgery.

Extranasopharyngeal angiofibroma arising from the nasal septum.

Extra nasopharyngeal origin of angiofibroma is very rare. The nasal septum is a very rare site of extra nasopharyngeal angiofibroma with only two cases reported in the medical literature. We report here a case of a vascular mass arising from the nasal septum of an 8 year old boy. Histopathology confirmed it to be a case of angiofibroma. A review is also made of the other reported cases of angiofibroma arising from the nasal cavity. The likely theory of origin of the tumor and the management is also discussed.
