Impact of inverted internal limiting membrane-flap technique on functional outcome and structural restoration of small and medium size macular holes

Purpose: To evaluate the impact of the inverted internal limiting membrane (ILM)?flap technique on the visual outcome and anatomical recovery for small (<250 ?), medium (<400 ?), and large (>400 ?) macular holes (MHs). Methods: Retrospective study included consecutive idiopathic MH cases operated on using the inverted ILM?flap technique. Clinical data were retrieved from electronic medical records (EMRs), surgical videos, and optical coherence tomography (OCT) machines. Eyes with axial length >25 mm, coexisting macular diseases, and follow?up <6 weeks were excluded. Data included the presence or absence of ILM flap and restoration of External Limiting Membrane (ELM), Ellipsoid Zone (EZ) lines. Mean visual improvement and structural recovery were compared between eyes showing ILM flap and those showing no flap in three MH size groups. Results: Forty eyes of 38 patients with a mean age of 62.7 ± 10.1 years and a mean MH diameter of 348 ± 152 ?m were included. The mean follow?up was 527 ± 478 days with anatomical closure observed in all eyes. Mean best?corrected visual acuity (BCVA) improved significantly from 0.87 ± 0.38 to 0.35 ± 0.26. ILM flap was visible in 29 (72.5%) all MHs, 7 (53.8%) small MHs (n = 13), 8 (61.5%) medium MHs (n = 13), and 14 (100%) large MHs (n = 14). The mean BCVA change was 0.47 ± 0.34, 0.53 ± 0.48, and 0.56 ± 0.20 in large, medium, and small MHs, respectively, and the difference between eyes showing ILM flap versus no flap in each MH size group was not statistically significant (P > 0.05). However, for medium MHs, it was higher in the ILM flap (0.66 ± 0.52) group compared to the no flap (0.32 ± 0.37) group. One eye with small MH developed significant gliosis resulting in reduced BCVA. ELM was restored in all eyes with small and medium MHs. Conclusion: We observed that the ILM flap did not adversely affect anatomical and visual outcomes for MHs <400 ?m. Restoration of ELM suggests minimal interference in structural recovery by an ILM flap.

Analysis of Various Histopathological Patterns in Pleomorphic Adenoma - An Institutional Case Study

Introduction: Pleomorphic adenoma, the most common benign mixed salivary gland tumor which accounts for 70-80%, is a biphasic tumor with dual origin from epithelial and myoepithelial elements. It shows a malignant transformation rate of 6%. Microscopically, pleomorphic adenoma characteristically displays vast morphologic diversity. This present study is done to analyze prevalence rates and histomorphological variations to better elucidate the pattern of occurrence, diagnosis and treat- ment plan of pleomorphic adenoma. Materials and Methods: This are a retrospective study which was conducted in a private institution, Chennai. Based on the proportion of parenchymal and stromal tumor components, the cases were classified into four subtypes as proposed by Foote and Frazell. Morphological patterns, cellular patterns, capsular alterations and Stromal components were analyzed and statisti- cally evaluated. Results: Our analysis showed an overall 0.87% of pleomorphic adenoma cases being reported were associated with minor salivary glands followed buccal mucosa and palate. All the reported cases showed Type II pattern with histological cellular pat- tern of spindle cells and ductal morphological pattern. Conclusion: We observed the great diversity of morphological aspects of the stroma in pleomorphic adenoma, in which many cases showed variation in morphology and cellularity associated with tumor location.

Knowledge and Awareness about Chair-Side Diagnostic Techniques for the Screening of Suspicious Oral Lesions among General Dental Practitioners - A Cross-Sectional Survey

Introduction: General dental practitioners (GDPs) play an important role in screening and early detection of oral potentially malignant disorders (OPMD) and oral cancer. Aim: This survey aims to assess the knowledge and awareness of general dental practitioners about chairside diagnostic techniques for screening of inflammatory oral lesions, potentially malignant lesions and oral cancer. Materials and Methods: GDPs (n=125) were surveyed about their knowledge about chairside diagnostic techniques for early detection and screening of suspicious oral lesions. The interview was based on a pre-structured questionnaire containing 14 closed ended questions. Chi square test was used for evaluating the association of survey parameters. Result: 95.2% of dentists do diagnosis and management of suspicious oral lesions along with chief complaints. There is a strong association between the educational status of GDPs and their method for management of suspicious oral lesions (p=0.002). 84.5% of the postgraduate GDPs are aware of chemiluminescence methods than graduate level GDPs (p =0.0009). Majority of the graduate GDPs are unaware of VELScope(p=0.0009). Usage of all non-invasive techniques was found to be less among graduate GDPs (p=0.002). Conclusion: The overall awareness of the dentists involved in the study were good and postgraduate GDPs are more aware and practically ahead about the non-invasive diagnostic techniques than graduate GDPs.

Comparison of Fracture Resistance of Endodontically Treated Teeth Restored with Different Aesthetic Post and Core Systems Under All Ceramic Restoration Luted with Two Types of Cements

Context: Fracture of endodontically treated teeth is a grave sequela that a clinician should seriously ponder. Suitable selection of restorative materials is a requisite for long?term clinical success. Aims: To compare the fracture resistance of endodontically treated teeth restored with three different posts luted using two different cements under all ceramic crowns. Settings and Design: This in vitro study was conducted in the Department of Prosthodontics, Government Dental College, Kottayam, Kerala, India. Methods and Material: Thirty endodontically treated single?rooted mandibular premolars in which post spaces were prepared and divided into three different groups. Group 1 (n = 10): zirconia post group. Group 2 (n = 10): quartz fibre post group. Group 3 (n = 10): glass fibre post group. Each group is sub?divided into two based on the luting system: resin?modified glass ionomer cement (RMGIC) or dual?cure resin cement (DCRC). The fracture resistance testing was performed in a universal testing machine with a crosshead speed of 0.5 mm/min. Statistical Analysis Used: The mean fracture resistance were analysed using independent sample Student t?test and one?way ANOVA. Results: Within the zirconia post group, the mean fracture resistance was higher in DCRC sub?group compared to the RMGIC sub?group and the difference was statistically significant (p = 0.017). The difference in fracture resistance between three different post systems was not found to be statistically significant with respect to both the luting systems. Conclusions: It was observed that when zirconia post is used, the mean fracture resistance was higher in dual?cure resin group compared to the resin?modified GIC group.

Usage Pattern of Fixed-dose Combinations at ICMR Network of Rational Use of Medicine Centres across India: Recommendations for Policymakers and Prescribers

Aim: Irrational use of medicines is a global problem. In India, one contributing factor is the availability of a large number of fixed-dose combinations (FDCs). To improve rational use and to strengthen policies, it is important to assess the usage patterns and rationality of FDCs. Methods: This study was conducted as part of a 1-year prospective cross-sectional analysis of prescriptions in the outpatient clinics of broad specialities from 13 tertiary care hospitals across India. Five most commonly prescribed FDCs in each center were analyzed. In addition, all the prescribed FDCs were classified as per the Kokate Committee classification and it was noted whether any of the FDCs were irrational or banned as per the reference lists released by regulatory authorities. Results: A total of 4,838 prescriptions were analyzed. Of these, 2,093 (43.3%) prescriptions had at least one FDC. These 2,093 prescriptions had 366 different FDCs. Of the 366 FDCs, 241 were rational; 10 were irrational; 14 required further data generation; and the remaining 96 FDCs could not be categorized into any of the above. Vitamins and minerals/supplements, antibacterial for systemic use, and drugs for gastroesophageal reflux disease (GERD) and peptic ulcer were the most used FDCs. Conclusion: Based on the finding that some prescriptions contained irrational FDCs, it is recommended that a rigorous, regular, and uniform method of evaluation be implemented to approve/ban FDCs and that prescribers be periodically notified about the status of the bans.

Intra-operative aberrometry versus conventional biometry for intraocular lens power calculation: A prospective observational study from a tertiary referral center

Purpose: To evaluate the per operative intra?ocular lens (IOL) power calculation using intra?operative aberrometry (ORA) and its comparison with conventional methods. Methods: Patients with cataract planned for phacoemulsification by a single surgeon under topical anesthesia were enrolled in this prospective observational study in this prospective observational study. All patients underwent pre?operative biometry (Manual SRK?II and IOLMaster® 500) to determine the intra?ocular lens (IOL) power. Intra?operative aberrometry using ORA was also performed; however, IOL was inserted according to IOLMaster® (SRK/T). Spherical equivalent (SE) was recorded on post?operative days 1, 7, and 30. Patients were divided into three groups based on axial lengths for analysis. Comparative analysis was performed for the calculated IOL powers and prediction errors of ORA with conventional methods. Adjusted IOL power to calculate the emmetropic IOL using the LiHue formula was also determined and was compared with existing methods. A P-value less than 0.05 was considered statistically significant. Results: A total of 115 eyes from 113 patients were included, with a median age of 54.90 ± 14.3 years. The mean axial length was found to be 23.94 ± 2.3 mm. There was good agreement (87%) between ORA and IOLMaster® for calculated IOL powers with a mean difference of 0.047 ± 0.5D between the two (P = 0.33). A positive correlation was found between IOL power calculated using ORA, IOLMaster®, SRK?II, and adjusted IOL. Conclusion: The use of intra?operative aberrometry (ORA) to calculate IOL power in patients undergoing uncomplicated phacoemulsification is non?inferior relative to standard pre?operative measurement and planning.

Simultaneous Estimation and Validation of Four Antiepileptic Drugs from Bulk and Formulations Using Reverse Phase HPLC

Abstract Epilepsy is a disorder of the central nervous system, in which the nerve cell activity in the brain is disturbed causing seizures. The objective was to develop an RP-HPLC method for consistent simultaneous quantitation of four antiepileptic drugs Levetiracetam (LVT), Lamotrigine (LTG), Phenobarbital (PBT) and Phenytoin (PTY). An isocratic method was developed on C18 column in JASCO HPLC using 5 mM potassium phosphate buffer (pH 6) and acetonitrile as the mobile phase at a flow rate of 1ml/min and detected at 230 nm using UV detector. The mean retention time for LVT, LTG, PBT and PTY were found as 2.55, 3.55, 4.65 and 5.99 minutes respectively. The method was validated as per ICH guidelines and was found to be acceptable. The %RSD value was <2.0 % thus stating the developed method was precise for the drugs in the given range. The accuracy values were within 85-115% of the recovery range. The specificity of the method was evaluated by an assay of marketed formulation, and it showed a percent content between 90-110% w/w for all the four drugs. The proposed analytical method was simple, accurate and robust and was precisely able to resolve the four major antiepileptic drugs. Hence, the current method can be applied successfully for routine examination of these drugs

Intersectionality Theory, Challenges for Empirical Research and Contributions to Psychology / Teoria da Interseccionalidade, Desafios para Pesquisas Empíricas e Contribuições para a Psicologia / Teoría de la Interseccionalidad, Desafíos para la Investigación Empírica y Aportes a la Psicología

Abstract The Theory of Intersectionality is an important contribution from feminist epistemologies to the scientific field. This narrative literature review aims to discuss methodological possibilities and challenges in producing and analyzing empirical evidence based on the Theory of Intersectionality, as well as its contributions to Psychology. While this theory is increasingly being cited as the basis for empirical research, articulating its assumptions in knowledge production processes is still a difficulty. Qualitative approaches prevail in the field, but advancements in statistical analysis methods allow for an intersectional interpretation in quantitative studies. Intersectionality contributes to understanding psychological processes and challenging dominant and exclusionary assumptions in the field of Psychology. Embracing this theory requires a commitment to the imperative of social transformation and entails placing claims, values, practices, and power relations at the core of scientific knowledge production, regardless of the field under study.

Resumo A Teoria da Interseccionalidade é uma importante contribuição das epistemologias feministas para o campo científico. Este estudo de revisão narrativa da literatura teve como objetivo discutir possibilidades e desafios metodológicos na produção e análise de evidências empíricas embasadas na Teoria da Interseccionalidade e suas contribuições para a Psicologia. Embora essa teoria esteja crescentemente sendo citada como base de pesquisas empíricas, ainda se identifica a dificuldade de articular seus pressupostos nos processos de produção de conhecimento. As abordagens qualitativas são predominantes no campo e observa-se avanços em métodos de análises estatísticas que permitem uma leitura interseccional em estudos quantitativos. A interseccionalidade contribui para compreender processos psicológicos e desafiar suposições dominantes e excludentes no campo da Psicologia. Adotar essa teoria requer uma implicação com o imperativo de transformação social e implica tornar reivindicações, valores, práticas e relações de poder como cerne da produção de conhecimento científico, independentemente do campo estudado.

Human Leukocyte Antigen-DQ Genotyping in Pediatric Celiac Disease / 대한소아소화기영양학회지

Purpose@#The purpose of this study was to determine the pattern of human leukocyte antigen (HLA)-DQ genotype in children diagnosed with celiac disease (CD) (biopsy proven), and to compare this with a control group; and secondarily, to correlate HLA genotypes with clinical profiles of CD. @*Methods@#This cross-sectional comparative observational study included 26 controls and 52 patients diagnosed with CD who presented at Sir Padampat Mother and Child Health Institute, Jaipur, from May, 2017 to October, 2018. HLA DQ genotype was assessed for each patients and correlated with clinical profiles. @*Results@#HLA DQ2/DQ8 genotypes were significantly more common in CD (present in 100.0% cases) than in controls (23.1%) in Northern India (Rajasthan). When HLA DQ2.5 and DQ8 were present together, individuals had significantly more atypical presentations and severe findings on duodenal biopsy. Similarly, patients with the HLA DQ 2.5 genotype were also predisposed to more severe endoscopic findings, while HLA DQ2.2 predisposed them to less severe biopsy findings. HLA DQ8 was significantly associated with later age at diagnosis (>5 years) and shorter stature. The highest HLA DQ relative risk (RR) for CD development was associated with HLA DQ2.5 and DQ2.2 in combination, followed by HLA DQ2.5 and DQ8 in combination, while HLA DQx.5 and HLA DQ2.2 together had the lowest risk. @*Conclusion@#HLA DQ2/DQ8 genotypes are strongly associated with pediatric CD patients in northern India. These genotypes and their combinations may be associated with different clinical presentations of CD, and may help predict severity of CD.

Efficacy of dorzolamide in improving ocular blood flow in patients with open-angle glaucoma: The Indian carbonic anhydrase inhibitor trial

Purpose: Impaired ocular blood flow is an important risk factor in the pathogenesis of open?angle glaucoma (OAG). Studies have reported that dorzolamide 2% may be effective in improving ocular blood flow (OBF) in OAG patients. The objective of this study was to determine the efficacy of dorzolamide 2% (DORZOX, Cipla Ltd.) in improving retrobulbar blood flow in an Indian setting. Methods: The study was conducted as an interventional pilot project in 24 healthy subjects and 19 OAG patients. Baseline OBF measurements were done for all glaucoma patients with color Doppler imaging (CDI). Baseline ocular perfusion pressure (OPP) was calculated for all participants. Glaucoma patients were given dorzolamide 2% thrice daily for 12 weeks. The primary efficacy endpoints were mean changes in the CDI parameters of the retrobulbar vessels and OPP posttreatment. The secondary endpoint was mean change in the intraocular pressure (IOP) and adverse events, if any. Results: In comparison to healthy subjects, glaucoma patients displayed significantly reduced baseline OPP (P = 0.002). Treatment with dorzolamide 2% for 12 weeks led to a significant increase in OPP (P < 0.001) and a significant increase in end diastolic velocity (EDV) in all major ophthalmic arteries like ophthalmic artery (OA), central retinal artery (CRA), and short posterior ciliary artery (SPCA) (P < 0.001, P = 0.04, and P = 0.0075, respectively). A significant reduction in the intraocular pressure (IOP; P = 0.007) was observed posttreatment, with no adverse events reported. Conclusion: Dorzolamide 2% significantly improved parameters such as the EDV and OPP in major ophthalmic arteries. This pilot study shows promising results on using dorzolamide for treating Indian patients with OAG

A correlation biomarker between BMI and lipid peroxidation in type 2 diabetes mellitus with and without other complications

Objectives: Body mass index (BMI) is a traditional measurement practice that divides a person’s weight by their height to find out whether they have a healthy range of weight. The objective of this study is to understand the relation between BMI and prevalence of diabetes mellitus, hypertension, and dyslipidemia. Material and Methods: BMI distribution among these patients was compared with and without hypertension and dyslipidemia. The improper of secretion of insulin leads to changes in metabolism of lipids, proteins, and carbohydrates also characterized hyperglycemia generally considered as diabetes mellitus (DM). Results: The excessive formation of free radicals induces oxidative stress, and the antioxidant defense system becomes weaken and hence arises diabetic disorder and overproduction of malondialdehyde (MDA). In cells, the polyunsaturated fatty acid peroxidation is considered as the final product and marker of oxidative stress. Conclusion: In this study, significantly increased BMI is observed in diabetic victims in comparison with control group. A significant positive correlation was noticed between glycated hemoglobin, cholesterol, and MDA. In conclusion, for the prevention and management of vascular complication in type 2 diabetes mellitus, maintaining normal levels of MDA and body weight are very important. Further large-scale studies are required to confirm it

Study of Clinico-mycological profile of onychomycosis at a tertiary carehospital

Introduction: Onychomycosis (OM) is a common nail disorder caused by dermatophytes, non-dermatophyte moulds and yeasts. The increased prevalence of OM along with the wide range of associated fungi necessitates the accurate laboratory isola?on and iden?fica?on of the causa?ve fungus for op?mal management strategies. The aim of the study was to evaluate clinical, epidemiological and mycological characteris?cs of OM at a ter?ary care hospital in Karimnagar. Materials and Methods: The study was conducted at Department of Microbiology for a period of one year. 109 pa?ents clinically diagnosed as OM were subjected to detailed history, clinical examina?on and inves?ga?ons. Nail clippings and subungual debris of OM pa?ents were subjected to KOH prepara?on and culture. Isolates were iden?fied by colony characters, pigment produc?on, microscopic morphology. Results: The maximum number of OM cases belonged to the age group 21-30 years with a male preponderance. Higher incidence was noted in males (71.5%) than females (28.4%). Direct microscopy of the nail clippings in 40% KOH solu?on was posi?ve in 56.8% and culture was posi?ve in 75.2% cases. The common e?ological agent was dermatophytes (45.12% cases) followed by yeasts (34.14% and non dermatophyte molds (20.7% cases). T.rubrum was the commonest among dermatophytes and Candida albicans among the yeasts. Conclusions: Although onychomycosis is not life threatening, it can cause a significant nega?ve impact on the quality of life of infected pa?ents. Early diagnosis and treatment is important to prevent distor?on of the nails which can prevent loss of working efficiency of the commonly affected popula?on.

Efficacy of serratus anterior plane block versus thoracic paravertebral block for postoperative analgesia after breast cancer surgery - a randomized trial

Abstract Background Breast cancer surgery is associated with considerable acute post-surgical pain and restricted mobility. Various regional and neuraxial anesthesia techniques have been used to alleviate post-mastectomy pain. Ultrasound-guided serratus anterior plane block (SAPB) has been considered a simple and safe technique. This randomized control study was performed to compare the efficacy of SAPB with the thoracic paravertebral block (TPVB) for postoperative analgesia after breast cancer surgery. Methods A total of 40 adult ASA physical status I - II female patients undergoing radical mastectomy were randomly allocated into two groups to receive either ultrasound-guided TPVB or SAPB with 0.4 mL.kg-1 0.5% ropivacaine, 30 min before surgery. All patients received standardized general anesthesia for surgery. Injection diclofenac and tramadol were used for postoperative rescue analgesia. The time to first rescue analgesia, total analgesic consumption in the first 24 hours, postoperative pain scores, and any adverse effects were recorded. Results The time to first rescue analgesia was significantly longer in the SAPB group (255.3 ± 47.8 min) as compared with the TPVB group (146.8 ± 30.4 min) (p< 0.001). Total diclofenac consumption in 24 hours was also less in the SAPB group (138.8 ± 44.0 mg vs 210.0 ± 39.2 mg in SAPB and TPVB group respectively, p< 0.001). Postoperative pain scores were significantly lower in the SAPB group as compared with TPVB group (p< 0.05). The incidence of PONV was also less in the SAPB group (p= 0.028). No block-related adverse effects were reported. Conclusion We found that the serratus anterior plane block was more effective than the thoracic paravertebral block for postoperative analgesia after breast cancer surgery.

COVID-19-related bilateral acute de-pigmentation of iris with ocular hypertension

A 43-year-old male patient presented with acute blurring of vision in both eyes associated with photophobia, redness, and mild pain following coronavirus disease 2019 (Covid-19) infection. Clinical examination revealed extensive pigment dusting in the corneal endothelium and the trabecular meshwork with de-pigmentation bands in the iris periphery. The patient was managed empirically with topical anti-glaucoma medications for high intra-ocular pressure. The patient was prescribed systemic antibiotics including cephalosporins and amoxicillin for respiratory symptoms. A rare condition called bilateral acute de-pigmentation of iris (BADI) was suspected after ruling out common entities, for example, viral kerato-uveitis, pigment dispersion syndrome, and Fuchs iridocyclitis. Covid-19 infection and systemic antibiotics including cephalosporins have shown to cause BADI in the literature. The patient responded well with good outcome.

Efficacy and safety of subliminal transscleral cyclophotocoagulation in uncontrolled glaucoma

Purpose: To determine the efficacy of subliminal cyclophotocoagulation in reducing intraocular pressure (IOP) and to assess the safety profile of the procedure. Methods: We reviewed the charts of all patients who underwent subliminal cyclophotocoagulation between August 2019 and August 2020. The IOP, number of antiglaucoma medications, and visual acuity were compared at baseline and at 6 months. The post-laser complications were noted. Paired t-test, Wilcoxon rank-sum test, and McNemar test were used for analysis. Results: This study included 40 eyes of 40 patients. The most frequent diagnosis was neovascular glaucoma (55%), followed by primary open-angle glaucoma (17.5%). The mean IOP reduced from 32 to 21 mmHg (mean IOP reduction: 32%, 95% confidence interval [CI]: 27%–37%, P < 0.001). Mean number of antiglaucoma medications declined from 3.2 to 1.9 (P < 0.001). Use of oral acetazolamide decreased from 62% to 5% (P < 0.001). The success rate of the procedure at 6 months was 55%. One patient had unexplained visual acuity decline after the procedure. Conclusion: Subliminal sub-cyclophotocoagulation is effective in treating refractory glaucoma in the Indian population. It decreases the medication burden. However, subliminal lasers can also cause vision-threatening complications such as hypotony, uveitis, and optic nerve hypoperfusion. So, clinicians should be cautious when using sub-cyclophotocoagulation in patients with good vision.

Benzene and Toluene concentration at different Traffic intersection during pre-mid-post winter season, in ambient air of Aligarh and its impact on human health

In current scenario, pollution in environment, is a big problem for all living species at around the world. We know that, Volatile Organic Compounds (VOCs) in presence of sunlight and oxides of nitrogen in atmosphere are considered as precursors for ozone production at the layer of Troposphere. Concentration of Benzene and Toluene (BT) in ambient air was measured near three major traffic sites in the city of Aligarh, India. All air samples were collected using for two times (in a month) during eight hours of normal working period time for in October – December 2020, and January - March 2021. The three selected sites used in this study represent traffic sites ( at Etah Chungi Chauraha, Quarsi Chauraha and Sootmil Chauraha, Aligarh ). In this study, real-time measurements of Benzene and Toluene concentration were performed the programmable compound specific PID detector designed to provide instantaneous exposure monitoring of a specific organic gas. It monitors a specific gas by utilizing a gas separation tube and the photo-ionization detector (PID) with a 9.8 eV gas discharge lamp (range- 50 ppb to 200 ppb) and whole data analyzed by SPSS software. The study the higher concentration 25.32 ?g/m3 of Benzene in the evening shows at site 3 and lower concentration 10.22 ?g/m3 of Benzene shows at site 2 in the morning. The higher concentration 22.22 ?g/m3 in the evening of Toluene shows at site 1 and lower concentration 07.10 ?g/m3 in the evening of Toluene shows at site 2, were observed respectively. Benzene and Toluene were widely used as a solvent in different products and petroleum. Exposure to a mixture of toluene and benzene in air led to an increase in the cytotoxic effect and DNA damage without any further repair and also its chronic effect on human health. The higher concentration of benzene and toluene co-exposure of benzene or toluene in this study. The relevance of these data on interactions for humans exposed at low benzene concentrations can be best assessed only when the mechanism of interaction is understood at a quantitative level and incorporated within a biologically based modelling framework for human health.

Effectiveness of Neonatal Resuscitation program training among MBBS interns in a Tertiary care hospital of South India

Background: Use of simulation-based learning methodologies enhance performance in both simulated resuscitations and real-life clinical situations. Retention of skill is very important for the MBBS doctors who hardly get any exposure to such learning before entering post-graduate courses. The major cause of early neonatal death is neonatal asphyxia, which can be prevented by neonatal resuscitation. Effective resuscitation at birth can prevent neonatal deaths to a greater extent. Training in cardio-pulmonary resuscitation is critical in determining successful outcomes in perinatal asphyxia. Hence the present study was done to check the retention of knowledge after Neonatal Resuscitation Program (NRP ) training. Methods: A prospective interventional study was carried out among the MBBS interns who started their internship program from March 2020 - February 2021 in ACSR Government Medical College, Nellore. All the Interns were given training in NRP as a part of internship orientation programme during the first week of internship. Out of 150 interns, 143 participated in the study. The interns were oriented to the study and a pretest questionnaire was administered to them to assess their knowledge and skill regarding NRP which was followed by NRP training by the faculty of pediatrics and neonatology. The same questionnaire was administered immediately at the end of the training, 1 and 6 months post NRP training for assessing their knowledge and skill. Results: As compared to pre intervention score, the mean scores of the immediate post intervention score and at 1 month after intervention the mean score was increased with respect to knowledge and skills. After 6 months the mean scores pertaining to knowledge and skill decreased which were statistically significant. Conclusions: A significant decrease in the level of knowledge and skills regarding neonatal resuscitation was observed. Therefore, maintaining resuscitation skill requires continuous practice, supplemented by simulation training as needed.
