Hearing assessment in mobile phone users

Background: Mobile phones have become an indispensable part of today's modern world. But with various day-to-day benefits, mobile phones also bring detrimental effects on the health of users. Ear being the closest organ in contact with phones, faces maximum effect of electromagnetic waves generated by them. Chronic exposure to these waves and sounds can result in permanent hearing loss. Hence, the present study was done to assess the association between hearing loss and duration of mobile usage. Methods: This cross-sectional study was conducted on mobile phone users between the age group of 20 and 40 years in the Department of ENT, Rajindra Hospital, Patiala over 6 months (1 August 2022 to 31 January 2023). 600 volunteers were involved and divided into three groups based on the duration of mobile phone usage. Pure tone audiometry and DPOAE were used to assess the hearing loss in these subjects. Results: A variable degree of hearing loss was observed on PTA and DPOAE in all three groups with a significant association between hearing loss and the duration of mobile phone usage. A higher proportion of sensorineural hearing loss was observed in the group with mobile phone usage of more than 1 hour per day for a minimum of 4 years as compared to those who used them for <1 hour per day for a minimum of 4 years and control group (p=0.001) which was significant statistically. Conclusions: People using mobile phones for long hours are at higher risk of developing hearing loss, especially in the dominant ear.

Outcome of newborn hearing screening a prospective study

Background: Hearing is a very important part of newborn language as well as speech development, hearing loss varies degrees i.e. from hearing impairment to complete hearing loss. It has an effect on person’s physical, social, mental, educational, and economic well-being. Methods: The current study's objective was to use OAE to test newborns for hearing in the department of otorhinolaryngology and study was carried out over a period of 2 years (September 2020 to September 2022) in 2000 neonates born at Rajindra hospital Patiala by DPOAE (distortion product OAE) test. The association between maternal, neonatal, sociodemographic factors and hearing impairment in neonates were evaluated. Results: In our study 257 out of 2000 newborns had ‘Refer’ result on OAE. There was a male preponderance (1061 males and 939 females) with 7% males having ‘Refer’ results as compared to 5.85% of females.153 out of 2000 neonates with ‘Refer’ result belonged to the lower class and 9.9% newborns with ‘Refer’ result was from rural area. Perinatal illnesses like Severe anemia (1.17%), Hypertension (0.78%) also have an impact on neonatal hearing impairment. In neonatal risk factors prematurity caused hearing impairment in 7.85% of neonates, low Apgar score at birth and 1 min (8.55% and 8.35%), low birth weight (8.75%), and more than 24-hour NICU admission (3.7%) Conclusions: The screening of neonates with Otoacoustic emissions is required for early detection of neonatal hearing loss as OAE is an easy,reasonably priced and dependable procedure for infant testing on a wide scale.

Quality of life after oesophagectomy in patients with carcinoma of oesophagus: A prospective study.

Background: The present study was done to see if quality of life improves following oesophagectomy for carcinoma of oesophagus. Materials and Methods: This was a prospective study done from June 2007 to July 2009. All patients undergoing oesophagectomy and cervical anastomoses for squamous cell carcinoma and adenocarcinoma of oesophagus were included in the study. Quality of life assessment was done using EORTC QLQ C-30 and its oesophagus specific module (OES-18) before surgery and at 3, 6, 9 and 12 months. Results: There were 55 patients who underwent oesophagectomy for carcinoma of oesophagus. On the EORTC functional scale it was noted that patients undergoing transhiatal oesophagectomy showed significant improvement of emotional function only. Patients undergoing transthoracic oesophagectomy showed a decrease in functional scores in the first three months which improved later but this change was not significant. On the EORTC symptom scale, patients undergoing transhiatal oesophagectomy showed significant improvement of constipation but not in other symptoms. Patients undergoing transthoracic oesophagectomy showed an increase in symptoms for the first three months followed by a decrease which was significant with respect to scores for constipation and pain. On the EORTC oesophagus specific symptom scores, patients in both groups showed significant improvement of dysphagia and eating. Conclusion: Patients with carcinoma of oesophagus undergoing transhiatal oesophagectomy may not show significant improvement in quality of life. However there will be significant improvement in dysphagia and eating. Patients undergoing transthoracic oesophagectomy may show an initial decrease in the quality of life.

Blood Levels of Pyrazinamide in Children at Doses Administered Under the Revised National Tuberculosis Control Program.

Objectives: To evaluate the blood levels, pharma-cokinetics and pharmacodynamic indices of pyrazinamide (PZA) in children suffering from tuberculosis, at doses administered under the weight band system of Revised National Tuberculosis Control Program of India (RNTCP) of India. Design: Prospective, open-label, non-randomized single-dose study. Setting: 20 children in the age group 5-12 years attending outpatient tuberculosis clinic of a tertiary hospital. Outcome Measures: Blood levels of pyrazinamide after single dose administration, as per the weight band system of RNTCP. Results: Group I (n=7) included children who received pyrazinamide within the recommended 30-35 mg/kg dose (mean 31.9+0.8 mg/kg) and Group II (n=13) included those who received a dose lower than 30 -35 mg/kg (mean 28.1±0.3 mg/ kg). The Cmax (95% CI of difference 2.2, 13.2; P=0.008) and AUC (95% CI of difference 28.6, 208.1; P=0.01) were significantly lower in Group II. The duration of time for which the concentration was maintained above 25 μg ml-1 was 4-8 h in Group I and 3-5.5 h in Group II (95% CI of difference 0.1, 2.0; P=0.03). The half life, elimination rate constant, clearance and volume of distribution were comparable in the two groups. The ratios of Cmax and AUC to MIC (25 μg ml-1) in children were lower than that recommended for PZA in adults. Conclusions: Lower blood concentrations are being attained in children receiving PZA doses under the existing weight band system of RNTCP of India. The weight bands may need to be revised and dose recommendations be based on pharmacokinetic and efficacy data in children.

Therapeutic radiological interventional procedures in hepatocellular carcinoma.

BACKGROUND: To improve the survival rate of patients with hepatocellular carcinoma (HCC) in whom surgery is not possible, various methods have been developed employing angiographic and percutaneous techniques. We analyzed our experience with various percutaneous therapeutic interventional techniques done for HCC in our center. METHODS: Sixty-one patients with inoperable HCC (mean age 48.9 [SD 13.8] y; 47 men) were treated between January 1997 and December 2000 by transcatheter arterial chemoembolization (TACE) alone (22), TACE with percutaneous alcohol injection (PEI) (20), transcatheter arterial embolization (TAE) with steel coils and gel foam for gastrointestinal bleed (7), percutaneous radiofrequency ablation (1), percutaneous preoperative right portal vein embolization (3) and percutaneous preoperative tumor embolization to reduce blood loss at surgery (8). RESULTS: In 42 patients treated by TACE and PEI and TACE alone, tumor necrosis was scored; over 50% necrosis was seen only after six and nine months in both treatment groups. The survival rates after six and nine months and the median survival were similar in the two groups. Of 7 cases treated with TAE with steel coils and gel foam, the gastrointestinal bleeding stopped in four; in the other three, bleeding did not stop completely although less transfusion was required. In the patient treated by radiofrequency ablation, follow-up contrast-enhanced CT did not show enhancing tumor mass. We noted left lobe enlargement after percutaneous preoperative right portal vein embolization, prior to right hepatectomy. CONCLUSION: In patients with HCC not amenable to surgical intervention, a variety of percutaneous therapeutic interventional techniques may be used.

Functional outcome and patient satisfaction after ileal pouch anal anastomosis for ulcerative colitis in a developing country.

AIM: To study the long-term outcome and patient satisfaction of patients with an ileal pouch-anal anastomosis (IPAA) for ulcerative colitis in India. PATIENTS AND METHODS: We studied 35 patients who had undergone IPAA for ulcerative colitis between 1985 and 1998 and had intestinal continuity restored for more than 6 months. These patients were asked to answer a detailed questionnaire on their bowel function, urogenital function, etc. A complete haemogram, serum iron studies, liver function tests and D-Xylose absorption test were done. In addition hepatobiliary ultrasound, stool microscopy, pouchoscopy and pouch biopsies were also performed. Patient satisfaction after the procedure was also evaluated. RESULTS: Thirty-five patients (17 men and 18 women) underwent a complete evaluation. The duration after restoration of continuity ranged from 6 months to 164 months (mean 78.6 months). The mean stool frequency was 7.2 stools per 24 hours. Five patients had urgency of stool, 9 had occasional soiling and 1 had major incontinence. Four patients had minimal restriction of social activities and 1 discontinued his employment. All patients were sexually satisfied except one man who had impotence and one woman who had dyspareunia. Fifteen patients had abnormal serum iron studies (Haemoglobin < 9 g/dl in 11). Eleven patients had D-Xylose absorption below normal values. Two patients were found to have gallstones. All pouch biopsies showed chronic inflammation and 1 patient had histological evidence of pouchitis. Eighty-five percent of patients reported that they were very satisfied with the procedure. CONCLUSION: Good functional recovery and acceptance of the procedure over the long term suggests that it is a valid procedure to be recommended for patients with ulcerative colitis in India.

Does exchanging comments of Indian and non-Indian reviewers improve the quality of manuscript reviews?

BACKGROUND: The quality of peer reviewing in developing countries is thought to be poor. To examine whether this was so, we compared the performance of Indian and non-Indian reviewers who were sent original and review articles submitted to The National Medical Journal of India. We also tested whether informing reviewers that their comments would be exchanged improved the quality of their reviews. METHODS: In a prospective, randomized, blinded study, we sent 100 manuscripts to pairs of peer reviewers (Indian and non-Indian) of which 78 pairs of completed replies were available for analysis. Thirty-eight pairs of reviews were exchanged and 40 were not. The quality of the reviews was assessed by two editors who were unaware of the reviewers' nationality and whether they had been told that their reviews would be exchanged. The quality of the reviews was scored out of 100 (based on a predesigned evaluation proforma). We also measured the time taken to return a manuscript. RESULTS: Overall, non-Indian reviewers scored higher than Indians (mean scores non-Indians first, 56.7 v. 48.6, p < 0.001), especially those in the non-exchanged group (58.4 v. 47.3, p < 0.001) but not the exchanged group (54.8 v. 50.0, p < 0.06). Being informed that reviews would be exchanged did not affect the quality of reviews by non-Indians (54.8 exchanged v. 58.4 non-exchanged) or of reviews by Indians (50.0 exchanged v. 47.3 non-exchanged). The editors' assessment of the reviewers matched well (r = 0.59, p < 0.001). Non-Indians took the same amount of time as Indians to return their reviews, although the postage time was at least eight days longer. CONCLUSIONS: We found that non-Indian peer reviewers were better than Indians and informing them that their views would be exchanged did not seem to affect the quality of their reviews. We suggest that Indian editors should also use non-Indian reviewers and start training programmes to improve the quality of peer reviews in India.

Benign cystic peritoneal mesothelioma in a man.

Benign cystic mesothelioma of the peritoneum is uncommon and usually occurs in women. We report this condition in a man, who was treated successfully by surgical excision of the tumor.

Gastrointestinal mucormycosis--an uncommon isolated mucormycosis.

BACKGROUND: Isolated mucormycosis of the gastrointestinal tract is uncommon, with only two case reports from India. OBJECTIVES: To study the clinicopathologic features of gastrointestinal mucormycosis in Indian patients. METHODS: Eight cases of isolated gastrointestinal mucormycosis, seen over six years (1992-97) are reviewed. RESULTS: Five of the patients were premature babies or infants, one was a 12-year-old boy, and two were middle aged. Symptomatology included vomiting, bloody diarrhea, upper gastrointestinal bleeding, abdominal lump and abdominal distention. All the neonates presented with intestinal perforation. The duration of symptoms was ten days or less in six cases. Mucormycosis was not suspected clinically in any patient. In six cases the diagnosis was established antemortem from resection or biopsy material. Only two patients received antifungal therapy and only one patient responded. CONCLUSIONS: Isolated gastrointestinal mucormycosis is not uncommon in India. Early diagnosis may be helpful in reducing the high mortality.
