Effect of Maternal Diabetes Mellitus on Neonatal Hearing.

Introduction: Gestational diabetes is a potential risk factor for neonatal hearing loss. Increased circulating sugars in mothers during pregnancy can impairs the micro circulation and can cause congenital anomalies of the inner ear resulting in congenital hearing loss. This study attempts to find the incidence of neonatal hearing loss among diabetic mothers. Methodology: This was a case control study with 86 neonates of diabetic mothers as cases and neonates of non diabetic mothers(n = 86) as controls. Antenatal diabetic history and sugar values of mothers were documented. Hearing status of the neonates were tested using DPOAE test and ABR test. DPOAE test was done on 3rd day and those who did not get a positive response underwent 2nd DPOAE and also ABR test if 2nd DPOAE was negative. Results: All neonates underwent DPOAE test and few were lost on follow up. First and second DPOAE showed a statistically significant difference between cases and controls. All babies who underwent ABR test had abnormal waveforms. 98% of cases showed moderate and severe bilateral hearing loss whereas all controls had only mild bilateral hearing loss. Discussion: This study showed a significantly higher percentage of abnormal hearing outcome among neonates of diabetic mothers than non diabetic mothers. This could be because of the toxic effects of maternal hyperglycemia on developing auditory system of the fetus. This study emphasis the need for better glycaemic control in diabetic pregnancy, the importance of early and mandatory hearing screening in newborns of diabetic mothers.

Pattern of disease expression in SLE patients with antiphospholipid antibodies: data from Indian Systemic Lupus Erythematosus Inception cohort (INSPIRE).

Antiphospholipid antibodies (APLA) are present in one-third of systemic lupus erythematosus (SLE) patients, and they are associated with both criteria and non-criteria manifestations. We studied the prevalence, clinical associations, and impact on mortality of APLA in SLE patients from India. Among the Indian SLE inception cohort (INSPIRE), patients who had data on all five routinely performed APLAs [lupus anticoagulant (LA), IgG and IgM anticardiolipin antibody (aCL) and anti-ß2-glycoprotein I(ß2GPI)] at enrolment were selected. Patients were divided into four categories based on the presence/absence of APLA associated manifestations and presence/absence of the APLA viz SLE-APS, SLE-APLA, SLE: events but no APLA, and SLE: no events, no APLA (reference group). 1035 SLE patients at least 1 APLA antibody was detected in 372 (35.9%). LA was present in 206 (19.9%), aCL in 126 (12.2%) and ß2-GPI in 178 (17.2%). There were 88 thrombotic events in 83 patients (8.0%); 73 (82.9%) being arterial; APLA positivity was present in 37 (44.6%) [AOR 1.70 (1.054, 2.76)]. SLE-APS patients were younger and had higher mortality [AOR 4.11 (1.51, 11.3)], neuropsychiatric and hematologic disease. SLE-APLA also had a higher mortality rate [AOR 2.94 (1.06, 8.22)] than the reference group. The mortality was highest in the subset of patients with thrombotic events in the presence of APLA [AOR 7.67 (1.25, 46.9)]. The mere presence of APLA also conferred higher mortality even in the absence of thrombotic events [AOR 3.51 (1.43, 8.63)]. Hematologic manifestations (36.1%) were the most common non-criteria-manifestation. One-third of SLE patients have APLA and its presence is associated with non-criteria hematologic manifestations, arterial thrombosis and higher mortality rate.

Effect of Adenotonsillectomy on Spectral and Acoustic Characteristics.

Acoustic analysis and perceptual analysis has been extensively used to assess the speech and voice among individual with voice disorders. These methods provide objective, quantitative and precise information on the speech and voice characteristics in any given disorder and help in monitoring any recovery, deterioration, or improvement in an individual's speech and also differentiate between normal and abnormal speech and voice characteristics. The present study was carried out to investigate the spectral characteristics (formant frequency parameters and formant centralization ratios) and voice characteristics (Acoustic parameters of voice) changes in individuals following adenotonsillectomy. A total of 34 participants participated in the study with a history of adenotonsillar hypertrophy. Spectral and acoustic voice parameters were analyzed across the three-time domains, before surgery (T0), 30 days (T1), and 90 days (T2) after surgery. Data was analyzed statistically using the SPSS software version-28.0.0.0. Descriptive statistics were used to find the mean and standard deviation. Repeated measures of ANOVA were used to compare the pre and post-experimental measures for spectral and acoustic, voice parameters. The derived parameter of acoustic vowel space (formant centralization ratio 3) was compared across three conditions timelines. The results revealed that acoustic vowel space measure and formant frequency measures were significantly increased in pre and post-operative conditions across the three timelines. A significant difference was obtained across the acoustic parameters across the time domains. Adenotonsillectomy has been proved to be an efficient surgical procedure in treating children with chronic adenotonsillitis. The results obtained have indicated an overall improvement in the spectral and acoustic voice parameters thereby highlighting the need for adenotonsillectomy at the right time and at the right age.

Vitamin D - An Elixir for Recurrent Upper Respiratory Tract Infection.

AIM: The aim of this study was to assess and compare the level of serum vitamin-D in participants affected with recurrent upper respiratory tract infections and in healthy population and to know whether vitamin-D deficiency is factor contributing to recurrent upper respiratory tract infections (URTI). Materials and Methods: A case control study was conducted on 52 subjects with recurrent URTI and 52 controls. Frequency and severity of infections in the previous 6 months were assessed and documented among the case group. Vitamin D level was assessed in all the participants among case and control group and statistical analysis was done. Results: Mean serum vitamin D was 10.67 ± 3.58 ng/mL in the study group and 20.10 ± 7.73 ng/mL in the control group, the difference in value was statistically significant. None of the study group participants belonged to vitamin D sufficient group, and majority (98%) were in vitamin D deficient, except for 2% who were in insufficient group. In the control group, 10%,29%,61% were in sufficient, insufficient and deficient group respectively. Mean serum vitamin D was not significantly associated with severity and type of infection. Conclusion: Significant number of participants in both study and control had serum vitamin D deficiency. This study also observed that a significant number of participants with recurrent URTI had serum vitamin D deficiency than the control group which suggest that hypovitaminosis D is a factor contributing to recurrent URTI.

Can Upper Airway Surgeries Improve Lower Airway Function ? A Prospective Study.

Deviated nasal septum and turbinate hypertrophy are the most common causes for nasal obstruction, which compromise nasal airflow and increases airway resistance. These conditions can further reduce the airflow to lung, which will affect the lung volume and function subsequently reduces the exercise tolerance. The present study aimed to evaluate the impact of upper airway surgeries like septoplasty and turbinoplasty on lower airway functions using simple tests like spirometry and 6 min walking test (6mWt). This research was a prospective study. There were 88 subjects in the study who completed follow up. Spirometry and 6mWt was performed 1 day before and 1 month after surgery in all subjects. Mean preoperative and postoperative values of spirometry (forced vital capacity (FVC),forced expiratory volume in 1 s (FEV1), forced expiratory volume in 1 s/ forced vital capacity (FEV1/FVC), peak expiratory flow rate (PEFR) and 6mWt (systolic blood pressure, diastolic blood pressure, heart rate and oxygen saturation) parameters were compared and analyzed. Percentage of improvement of each parameter was compared with the type of surgery, side of obstruction, age of the patient and duration of symptom. Spirometry showed statistically significant improvement in all 4 parameters after surgery in 86 subjects. 6mWt showed statistically significant improvement in SBP and SpO2 and there was no significant improvement in DBP and HR. We also observed that improvement in parameters was irrespective of age and duration of symptoms. So this study concludes that airway narrowing nasal diseases can compromise lower airway function.

Clinico-radiological Co-relation of Carcinoma Larynx and Hypopharynx: A Prospective Study.

The successful management of laryngeal and hypopharyngeal cancers requires accurate diagnosis, staging, assessment of patient wishes, and the selection of the most appropriate treatment for the individual patient. Imaging plays an important complementary role to clinical examination and endoscopy in the evaluation of laryngeal and hypopharyngeal cancers. The combined information allows the disease to be staged accurately. To correlate carcinoma larynx and hypopharynx clinically and radiologically and to know the accurate pre-therapeutic stage of the disease. A total of 50 cases were included in this study. After clinical TNM staging, CT scan was done to know the real extent of tumor, volume and nodal status. After that, TNM staging was revised based on radiological findings. The number of people who had been upstaged and downstaged after CT evaluation was measured. There were total of 50 cases of carcinoma larynx and hypopharynx in this study. There were 26 (52%) cases of carcinoma larynx and 24 (48%) cases of carcinoma hypopharynx. There were significant changes in T stage after radiological evaluation. Major changes were observed in T2 and T3 stages. Majority of cases (17) were having N1 disease after radiological evaluation. On comparing clinical and radiological staging of neck nodes, it was observed that upstaging occurred mainly in N0. Overall after radiological evaluation, 48% of our cases were upstaged, 48% remained in same stage and 4% were downstaged. By combining both clinical and radiological evaluation in laryngeal and hypopharyngeal cancers, a correct pre therapeutic staging can be obtained and thereby prompt treatment can be given.
