Understanding perspectives of asthma among pulmonologists in Indian settings: results from a questionnaire-based survey

Background: Asthma is associated with high morbidity and mortality in India. This survey was undertaken to explore the perspectives of pulmonologists towards in-clinic management of patients with asthma. Methods: It was a cross-sectional survey of pulmonologists conducted across India. It was formulated to provide unbiased observations of real-world clinical practice focusing on methods of diagnosis of asthma and its treatment preferences. Results: The participants included 805 pulmonologists, with the majority primarily treating patients with asthma (62%), chronic obstructive pulmonary disease (19%) and allergic rhinitis (19%). More than 86% of pulmonologists consider clinical symptoms, history of childhood asthma, family history, and chronic allergic rhinitis for initial diagnosis. About 19-23% prefer spirometry alone or in combination with family history for confirmation of asthma. The preferred inhaled corticosteroids-long-acting bronchodilator (ICS-LABA) combination was budesonide-formoterol amongst 83% of pulmonologists. For both dry powder inhaler (DPI) and metered dose inhaler (MDI) devices, fine particle fraction per cent and delivered dose were ranked as the two most important attributes. Conclusions: Asthma is the most prevalent diagnosis among patients treated by pulmonologists on the basis of clinical presentation and medical history. The most commonly used pharmacotherapy for the treatment of asthma comprises ICS-LABA, with budesonide-formoterol being the preferred combination. Fine particle fraction per cent and magnitude of delivered dose influence the choice of asthma inhaler prescriptions the most.

Correlation of SARS-Cov2 viral load with severity of COVID-19 disease in pregnant women at term: an observational study

Background: COVID-19 disease raised global health concerns especially for the pregnant women who are more susceptible to respiratory viral illnesses due to their bodily immunological and physiological changes to accommodate the foetus. The aim of the study is to evaluate the relationship between the SARS-CoV 2 specific RdRp gene Ct values ??and the severity of the COVID-19 disease in SARS-CoV2 positive pregnant women at term. Methods: A retrospective cohort study was conducted in the Department of Microbiology, Government Medical College, Amritsar on a subset of 46 COVID-19 positive, ante natal mothers, who presented in the labour room for delivery from August 2020 to January 2022. Results: A cohort of 4.8% (46/949) women tested positive in the RT-PCR test for viral RNA. Average age of the group was 25.5years and 89.1% were asymptomatic. 10.9% women reported mild symptoms and 95% had no pre-existing co morbidities. Obstetric complications like premature rupture of membranes were 4.3%, pre-term births 17.33%. Miscarriage and IUD was recorded in 4.34% and 2.17% patients respectively. When compared to values seen in symptomatic women with fever (Ct 25.8), dyspnoea (Ct 28.7), and respiratory distress (Ct 29.1), the mean Ct value reported in asymptomatic women (27.49 SD+5.4) was identical. SARS-CoV2 was not present in any newborns. Despite 24% having low birth weights for their gestational ages, 93% of babies were asymptomatic. Conclusions: The severity of the COVID-19 illness did not correspond with the SARS CoV2 virus RdRp gene Ct levels. The presence of SARS-CoV2 did not appear to independently cause poor maternal and new-born outcomes.

Factors Affecting Under-Five Mortality Rate (U5MR) in India- National Family Health Survey (NFHS) 5 Factsheet What It Speaks?

Introduction: In developing countries various factors lead to Under-5 Mortality and irreversible losses which can be prevented by proper measures take on factors affecting to it. Objective: This study was conducted to analyse the changing trends of Under-5 Mortality in India. The new National Family Health Survey (5th round) which was published recently came up with several new findings, which were both encouraging and disheartening and also one of the major Sustainable Development Goals.Method: A secondary data analysis was conducted of NFHS factsheets to study the U5MR in India. The indica-tors which had a correlation either positive or negative with the Under-five mortality rate were included.Result- When we look at the result, few states' performance is encouraging because they have shown some of the best declines. Correlation was found between dependant variable that is U5MR which is a dependent vari-able and several independent variables which concluded that factors like Women literacy, Men literacy, Breastfeeding, Nutritional insufficiencies, Caesarean delivery, ANC visits and IFA consumptions are negatively associated withU5MR. Conclusion: Various steps have been taken in order to improve our healthcare sector since independence, every government had their fair share of contribution, that’s the reason why we are this stage. Now it’s time to increase efforts with targeted interventions to solve this problem and complete our commitment towards the SDGs.

Arcuate keratotomy infiltration following uneventful femtosecond laser assisted cataract surgery

An 84-year-old gentleman underwent uneventful femtolaser-assisted cataract surgery (FLACS) with an arcuate keratotomy (AK) in the left eye. On the 18th post-operative day, a corneal infiltrate developed involving the AK. Staphylococcus epidermidis was the organism isolated on culture. The infiltrate resolved with topical fortified vancomycin and amikacin eyedrops, and the patient regained a visual acuity of 6/6 after 12 weeks. This is the first case from south-east Asia reported in the literature of an infective infiltrate along a femtosecond laser AK. We propose strict peri-operative recommendations to be followed to prevent and treat such infections.

Pars plana vitrectomy and re-directing a dexamethasone implant into vitreous cavity following misdirected entry into the crystalline lens

A known diabetic patient presented with diabetic macular edema (DME) and nonproliferative diabetic retinopathy in both eyes with a vision of 6/18, N12in the right eye and 4/60, N36in the left eye (LE). The patient had undergone injection of dexamethasone implant in the LE which got misdirected into the crystalline lens. The patient was taken up for phacoemulsification with intraocular lens implantation along with vitrectomy and posterior vitreous detachment induction, and redirection of the dexamethasone implant into the vitreous cavity. The DME resolved over the next 3 months

Visual inspection of cervix with Lugol's iodine for early detection of premalignant & malignant lesions of cervix.

Background & objectives: Majority of cases of cervical cancer are diagnosed at an advanced stage as cytology based screening programmes are ineffective in developing countries. The present study was done to look for carcinoma cervix and its precursors by visual inspection with Lugol's iodine (VILI), visual inspection with acetic acid (VIA) and Papanicolaou smear, and to analyse their sensitivity, specificity and predictive values using colposcopic directed biopsy as reference. Methods: In this cross-sectional study, 350 women were subjected to Pap smear, VIA, VILI and colposcopy. Cervical biopsy and endocervical curettage was taken from patients positive on any of these tests and in 10 per cent of negative cases. Results: The Pap smear was abnormal in 3.71 per cent, including (2.85%), low grade (LSIL) and (0.85%) high grade squamous intraepithelial lesions (HSIL). Thirteen per cent of the patients were found to be positive by VIA and 11.71 per cent were positive on VILI. Sensitivity for VIA, VILI and Pap smear was 89.5, 100 and 52.6 per cent, respectively, while the specificity for VIA, VILI and Pap smear was 91.2, 93.3 and 99.1 per cent, respectively. Interpretation & conclusions: In low resource settings, cervical cancer screening by Pap smear can be replaced by visual methods like VILI, which has the highest sensitivity (100%) to detect any grade of dysplasia, and a good specificity (93.3%).

Primary squamous cell carcinoma of the renal parenchyma.

No case of a primary renal parenchymal squamous cell carcinoma (SCC) has been reported previously in the literature although renal pelvic SCCs are well known. We report an unusual case in a 60-year-old lady who presented with significant weight loss. She was found to have a mid and lower pole left renal tumor with enlarged para-aortic nodes. A left radical nephrectomy and nodal dissection was performed and the pathological stage was T4N1M0. No adjuvant therapy was given. She is alive at 13 months post-surgery.

Regional brain metabolism in schizophrenia: The influence of antipsychotics.

BACKGROUND: Schizophrenia has been associated with a plethora of metabolic changes in the brain that vary with duration and type of psychoses. Additionally, it has been observed that antipsychotics can further alter cerebral glucose metabolism. These changes resulting from antipsychotics have been postulated to be reflective of the duration and mechanism of action of the medication. AIMS: We aimed to examine the influence of antipsychotics on brain metabolism in individuals with schizophrenia in a naturalistic setting. SETTINGS AND DESIGN: A cross-sectional study was carried out by the psychiatry department of a tertiary care hospital in collaboration with the Radiation Medicine Centre. MATERIALS AND METHODS: Eighteen male patients with schizophrenia in different phases of treatment underwent an 18F-deoxyglucose positron emission tomography scan in a resting state 12 hours after the last dose of antipsychotic. Statistical Analysis: The types and duration of treatment were then compared with the regional glucose uptake in 14 predetermined regions of interest. The relative Uptake Values were further compared using SPSS 11.0. RESULTS: An immediate increase followed by a decrease in cortical uptake was noted while the basal ganglia uptake remained high, albeit with a decreasing trend. Typical antipsychotics were associated with lower frontal cortical and higher basal ganglia and cerebellar uptake as compared to atypical antipsychotics. CONCLUSION: The differential influence of the type and duration of antipsychotic on glucose uptake suggests a possible trend towards long-term side effects with typical medications that were not noted on clinical examination. This however needs to be confirmed with larger, controlled studies.

Seroprevalence of Chalmydia trachomatis infection amongst patients with pelvic inflammatory diseases and infertility.

Chlamydia trachomatis (C. trachomatis) is a common cause of pelvic inflammatory disease in female population. This infection can be diagnosed both by culture and serology. The present study evaluated the seroprevalence of chlamydial infection in patients with pelvic inflammatory disease (ND) and infertility and in control population of healthy normal females. The seroprevalence was found to be 82.7% in patients and 32% in controls by Enzyme Linked Immuno Sorbent Assay (ELISA) for any one or more class of antichlamydial antibodies (IgG/IgM/ IgA). The study demonstrates the importance of serology to monitor trends of chlamydial infections in women with PID and infertility.

Ciprofloxacin-tinidazole combination, fluconazole- azithromicin-secnidazole-kit and doxycycline- metronidazole combination therapy in syndromic management of pelvic inflammatory disease: a prospective randomized controlled trial.

BACKGROUND: Pelvic inflammatory disease is a common problem faced by the gynecologists in there out patient department. AIM: The aim of the study was to evaluate the efficacy of three treatment combinations in the syndromic management of pelvic inflammatory disease in the out patient setting. SETTING DESIGN: In the medical college hospital patients presenting in gynecology out patient department were enrolled. MATERIAL AND METHODS: One hundred and sixty five women with diagnosis of pelvic inflammatory disease were randomized into three equal groups getting ciprofloxacin (500 mg) and tinidazole (600 mg) combination twice daily for 7 days (Group 1), a kit containing fluconazole (150 mg), azithromycin (1 gm) and secnidazole (2 mg) as one time dose (Group 2) and Doxycycline 100mg twice daily and metronidazole 200 mg thrice daily for seven days (Group 3). Severity score was determined on first visit and after 1 week and 4 weeks when patients were called for follow up. Statistical Analysis: Chisqare test, Krusker wallis test and Mann Whitney test. RESULTS: There was significant reduction in severity score after 1 week of treatment, which was further reduced after 4 weeks in all the three groups. Cure rate was highest in-group 1 (96%) followed by group 2 (93.5) and group 3 (91.3%) but the difference was not statistically significant. Resolution of inflammatory mass was highest in group 1. The incidence of side effects was highest and compliance was lowest in the doxycycline -metronidazole group, but the difference was not statistically significant. CONCLUSION: All the three treatment combinations were found to be equally effective in the syndromic management of pelvic inflammatory disease.

CSF interleukin-1 beta, tumor necrosis factor-alpha and free radicals production in relation to clinical outcome in acute bacterial meningitis.

OBJECTIVE: To study the relationship of CSF IL-1 beta and TNF-alpha with free radicals in acute bacterial meningitis (ABM) and to evaluate the clinical outcome in relation to the levels of these cytokines and free radicals in CSF. DESIGN: Prospective with controls. SETTING: Referral unit of a teaching hospital. METHODS: 32 children between 3m-12 yrs of age with proven acute bacterial meningitis comprised the study group. In the control group, 20 children with febrile seizures were included. CSF cytokines- Interleukin Ib and tumour necrosis factor a,free radicals O(2)-, H(2)O(2) and enzymes SOD and CPK were measured in all the children. RESULTS: CSF IL-Ib and TNF-a concentration were markedly elevated in children with ABM (441.5 +/- 216.1 pg/ml, and 1009 +/- 529.1 pg/ml, respectively) as compared to controls (52.67 +/- 6.92 pg/ml, and 86.42 +/- 16.24 pg/ml) (p <0.0001). Free radicals viz., superoxide anion, hydrogen peroxide production and enzymes creatinine phosphokinase and superoxide dismutase were also significantly elevated in ABM as compared to controls. There was direct correlation of CSF cytokines with CSF cytology, protein and free radicals production in ABM. Patients who expired or had neurological sequelae had markedly elevated concentrations of cytokines and free radicals. CONCLUSION: IL-I beta, TNF-alpha and free radicals are significantly elevated in CSF of patients with ABM. The concentration of these cytokines correlated well with free radical production, and with routinely measured CSF parameters and had a direct bearing on outcome of ABM

Free oxygen radicals in acute renal failure.

OBJECTIVE: To assess the levels of free oxygen radicals in acute renal failure and their predictive value in clinical outcome. DESIGN: Prospective. SETTING: Intensive care unit. METHODS: Study was conducted in 50 children (25 with acute renal failure and 25 age and sex matched controls). Blood urea, serum creatinine, serum protein, uric acid and free oxygen radical markers were estimated in both groups. Superoxide dismutase (SOD), glutathione peroxidase(GPx) and lipid peroxide (LPO) were estimated in blood by standard techniques. RESULTS: Hemolytic uremic syndrome (HUS) was a major cause of acute renal failure (52%), rest were due to acute glomerulonephritis (AGN), septicemia and renal venous thrombosis. In the renal failure group 56% of the patients were dialyzed (peritoneal) and the mortality was 28% (7/25). The levels of SOD, GPx and LPO were significantly raised in renal failure group. Higher values of LPO, SOD and GPx were documented in subjects who expired. The most important independent variable for predicting clinical outcome was LPO with a sensitivity of 89.4%, specificity of 93%, positive predictive value of 95%. CONCLUSION: Levels of free oxygen radicals (SOD, LPO and GPx) are raised in acute renal failure and these enzymes can be used as marker of renal injury. LPO levels are highly sensitivity and specific for predicting the clinical outcome

Seroepidemiology of hepatitis A in Delhi.

A prospective study was done to determine the age specific prevalence of antihepatitis A antibodies (anti HAV Abs) among children in Delhi. Four hundred and twenty children aged 0-12 years attending outpatient department for vaccination or any minor illness were studied. Sera was tested by ELISA for anti HAV Abs using a commercial kit (Hepvase A 96 TMB). Thirty samples of cord blood were similarly analyzed. All samples of cord blood were positive for anti HAV Abs. Prevalence of anti HAV Abs was 80% by 5 years of age. The most vulnerable age group was 0.5-1.5 years (anti HAV Ab positivity). Cord blood had 100% positivity. Univariate and multivariate analyses taking anti HAV antibody positivity as dependant variable demonstrated that age and father's education (socioeconomic status) significantly affect prevalence of anti HAV Abs. Sex, water supply, history of jaundice in self or family did not have any significant effect on anti HAV antibody positivity. Prevalence of anti HAV antibodies is 80% by 5 years of age. Further studies in different strata of society and different regions in the country are required to assess the need and age for vaccination.

Serum TNF-alpha and free radical scavengers in neonatal septicemia.

Tumor necrosis factor-alpha (TNF-alpha) and free radicals have been implicated in the pathogenesis of neonatal septicemia and its complications. This case control study was conducted between November 1996 to July 1997 to determine the levels of TNF-alpha and free radical scavengers viz. superoxide dismutase (SOD) and glutathione peroxidase (GPX) in the serum of 30 septic neonates and 20 healthy controls. Patients with neonatal sepsis registered significantly higher levels of TNF-alpha, SOD and GPX in comparison to controls (p < 0.05). The neonates with septic shock had five fold increase in TNF-alpha levels (2262 +/- 605.8 pg/ml) as compared to those without shock (738.8 +/- 728.8 pg/ml). There was no statistically significant difference in levels of antioxidant enzymes between neonates with shock and without shock. The levels of TNF-alpha and antioxidant enzymes were not affected by the type of organism isolated in blood culture.

Status of lipid peroxidation and antioxidant enzymes in hypoxic ischemic encephalopathy.

OBJECTIVE: To compare the activities of key antioxidant enzymes [superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase] and the level of malonyl dialdehyde (MDA) in neonates with hypoxic ischemic encephalopathy (HIE) and controls. DESIGN: Prospective cross sectional study. SETTING: Tertiary care level II neonatal unit of teaching hospital. METHODS: Fifteen term new borns with HIE were registered for the study whereas normal term appropriate for gestational age babies were enrolled as controls. Clinical features were recorded. Activities of SOD, GPx, catalase and the content of MDA were estimated at 24 hours of age. The results obtained were statistically analyzed. RESULTS: Activities of SOD and Catalase and the level of MDA were significantly higher in cases as compared to the controls. There was however no significant alternation in the activity of GPx levels in both the groups. CONCLUSION: The increased activities of antioxidant enzymes are unable to counteract the excessively generated oxidants in vivo, as is evident from the increased MDA levels. Hence, oxygen free radicals may play a significant role in the pathogenesis of HIE.

Changes in anti-oxidant enzymes and lipid peroxidation in hyaline membrane disease.

This study was conducted to elucidate the changes in key antioxidant enzymes e.g. Superoxide dismutase (SOD), Catalase and Glutathione peroxidase (GPx) along with lipid peroxidation (LPO) in preterm newborns having hyaline membrane disease (HMD) and thus to find out role of free radicals mediated injury in this disease. Twenty one preterm appropriate for gestational age newborns were included in the study. Eleven of them had hyaline membrane disease and ten were controls without any disease. Status of superoxide dismutase, glutathione peroxidase and catalase, the three main antioxidant enzymes and lipid peroxidation was monitored at 12-24 hours of age. SOD and catalase were found significantly elevated in cases having hyaline membrane disease along with significantly more lipid peroxidation. It is evident that free radicals result in the induction of the antioxidant enzymes; however, the elevated enzymes are unable to counteract the high concentration of the free radicals which are being produced in the diseased cases and leads to increase in lipid peroxidation in hyaline membrane disease. It is concluded that free radicals play a significant role in hyaline membrane disease and the preterm newborns have ability to induce antioxidant enzymes in response to oxidative stress.
