RESUMEN

BACKGROUND: The utility of Adaptive Radiotherapy (ART) in Head and Neck Squamous Cell Carcinoma (HNSCC) remains to be ascertained. While multiple retrospective and single-arm prospective studies have demonstrated its efficacy in decreasing parotid doses and reducing xerostomia, adequate randomized evidence is lacking. METHODS AND ANALYSIS: ReSTART (Reducing Salivary Toxicity with Adaptive Radiotherapy) is an ongoing phase III randomized trial of patients with previously untreated, locally advanced HNSCC of the oropharynx, larynx, and hypopharynx. Patients are randomized in a 1:1 ratio to the standard Intensity Modulated Radiotherapy (IMRT) arm {Planning Target Volume (PTV) margin 5 mm} vs. Adaptive Radiotherapy arm (standard IMRT with a PTV margin 3 mm, two planned adaptive planning at 10th and 20th fractions). The stratification factors include the primary site and nodal stage. The RT dose prescribed is 66Gy in 30 fractions for high-risk PTV and 54Gy in 30 fractions for low-risk PTV over six weeks, along with concurrent chemotherapy. The primary endpoint is to compare salivary toxicity between arms using salivary scintigraphy 12 months' post-radiation. To detect a 25% improvement in the primary endpoint at 12 months in the ART arm with a two-sided 5% alpha value and a power of 80% (and 10% attrition ratio), a sample size of 130 patients is required (65 patients in each arm). The secondary endpoints include acute and late toxicities, locoregional control, disease-free survival, overall survival, quality of life, and xerostomia scores between the two arms. DISCUSSION: The ReSTART trial aims to answer an important question in Radiation Therapy for HNSCC, particularly in a resource-limited setting. The uniqueness of this trial, compared to other ongoing randomized trials, includes the PTV margins and the xerostomia assessment by scintigraphy at 12 months as the primary endpoint.

RESUMEN

Background: This study aimed to investigate the association between household air pollution and chronic respiratory illness (CRI) in Jaipur, India. Materials and Methods: A total of 147 participants over 18 years of age from 45 households were randomly included in the study, and follow-up visits were conducted once every fortnight over a three-month period. Spirometry tests were conducted using a portable hand-held digital spirometer. A self-designed, pretested, semi-structured questionnaire was utilized to collect socio-demographic information from the participants. Statistical tests, such as t-tests were used to analyze the association between household air pollution and CRI. Results: The prevalence of COPD and bronchial asthma was 2% and 4%, respectively. Various risk factors for CRI were identified within households, and only 4 episodes of acute exacerbation of chronic respiratory illness were observed, resulting in no incidence density calculation. The mean values of forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were significantly lower in females (P < 0.001) Also, the mean values of FVC and FEV1 were significantly lower in rural areas (P < 0.005) than urban areas. Conclusion: Our findings highlight the importance of government and stakeholder action to implement clean air policies and protect respiratory health. Further studies are needed to expand on these findings and delve deeper into understanding the complex interactions between various risk factors and respiratory health in this population.

RESUMEN

BACKGROUND: As per the guidelines of the Indian Council of Medical Research, nasopharyngeal and oropharyngeal swabs in viral transport medium (VTM) are to be stored at 4 °C for less than 5 days and for more than 5 days at -70 °C. Samples are not transported or stored as per prescribed conditions because of the limitations, resulting in an apprehensive diagnosis. The aim of the study was to test the stability of the SARS-CoV-2 sample stored in VTM at different temperatures. METHODS: In this study, the stability of 21 positive and 9 negative samples for SARS-CoV-2 was evaluated in commercial VTM at different temperatures (-80 °C, -20 °C, 4 °C, and 25 to 30 °C). Stability was checked for up to 50 days in the above storage conditions at different intervals. PathoDetect™ and Hi-PCR® kits were used for the detection of the four genes of SARS-CoV-2. The Cycle Threshold (Ct) value for determining the positivity of samples for PathoDetect™ was < 40 and for Hi-PCR® was < 38. RESULTS: The SARS-CoV-2 confirmatory genes (RdRp and E genes) and the internal housekeeping gene remained detectable even on the 50th day of the study. The Ct of the RdRp and E genes were found to increase with storage duration, but all positive samples remained positive till the end of the study, or the Ct value remained below the cut-off level. The negative samples gave consistent results until the end of the study. When the differences in Ct values were compared between the days in a set of experiments, they were not significantly different except in a few samples. CONCLUSION: The SARS-CoV-2 genetic materials in commercial VTM were stable at room temperature to -80 °C for 50 days.

RESUMEN

Plastic recycling reduces the wastage of potentially useful materials as well as the consumption of virgin materials, thereby lowering the energy consumption, air pollution by incineration, soil and water pollution by landfilling. Plastics used in the biomedical sector have played a significant role. Reducing the transmission of the virus while protecting the human life in particular the frontline workers. Enormous volumes of plastics in biomedical waste have been observed during the outbreak of the pandemic COVID-19. This has resulted from the extensive use of personal protective equipment such as masks, gloves, face shields, bottles, sanitizers, gowns, and other medical plastics which has created challenges to the existing waste management system in the developing countries. The current review focuses on the biomedical waste and its classification, disinfection, and recycling technology of different types of plastics waste generated in the sector and their corresponding approaches toward end-of-life option and value addition. This review provides a broader overview of the process to reduce the volume of plastics from biomedical waste directly entering the landfill while providing a knowledge step toward the conversion of "waste" to "wealth." An average of 25% of the recyclable plastics are present in biomedical waste. All the processes discussed in this article accounts for cleaner techniques and a sustainable approach to the treatment of biomedical waste.

RESUMEN

AIMS: This multicentric retrospective study reports long-term clinical outcomes of non-metastatic grade group 5 prostate cancers treated with external beam radiotherapy (EBRT) alone with long-term androgen deprivation therapy (ADT). MATERIALS AND METHODS: Patients treated across 19 institutions were studied. The key endpoints that were evaluated were 5-year biochemical recurrence-free survival (bRFS), metastases-free survival (MFS), overall survival, together with EBRT-related acute and late toxicities. The impact of various prognostic factors on the studied endpoints was analysed using univariate and multivariate analyses. RESULTS: Among the 462 patients, 88% (405) had Gleason 9 disease and 31% (142) had primary Gleason pattern 5. A prostate-specific membrane antigen positron emission tomography-computed tomography scan was used for staging in 33% (153), 80% (371) were staged as T3/T4 and 30% (142) with pelvic nodal disease. The median ADT duration was 24 months; 66% received hypofractionated EBRT and 71.4% (330) received pelvic nodal irradiation. With a median follow-up of 56 months, the 5-year bRFS, MFS and overall survival were 73.1%, 77.4% and 90.5%, respectively. Primary Gleason pattern 5 was associated with worse bRFS, MFS and overall survival with hazard ratios of 0.51 (95% confidence interval 0.35 to 0.73, P < 0.001), 0.64 (95% confidence interval 0.43 to 0.96, P = 0.031) and 0.52 (95% confidence interval 0.28 to 0.97, P = 0.040), respectively, whereas pelvic nodal disease was associated with worse bRFS (hazard ratio 0.67, 95% confidence interval 0.46 to 0.98, P = 0.039) and MFS (hazard ratio 0.56, 95% confidence interval 0.37 to 0.85, P = 0.006). The acute and late radiation-related toxicities were low overall and pelvic nodal irradiation was associated with higher toxicities. CONCLUSION: Contemporary EBRT and long-term ADT led to excellent 5-year clinical outcomes and low rates of toxicity in this cohort of non-metastatic grade group 5 prostate cancers. Primary Gleason pattern 5 and pelvic node disease portends inferior clinical outcomes.

RESUMEN

Brachytherapy for localised prostate, muscle-invasive bladder and penile cancer is well established, providing high tumour dose delivery and minimising normal tissue doses compared with external beam techniques. In prostate cancer, the main impact on quality of life relates to diminished sexual function and irritative or obstructive urinary symptoms, which are seen up to 15 years after treatment. Significant changes in bowel function are rare. Compared with radical prostatectomy or external beam radiotherapy, irritative or obstructive urinary symptoms are more prominent, whereas incontinence is less than after radical prostatectomy and bowel changes are less than after external beam radiotherapy. For muscle-invasive bladder cancer, when compared with radical cystectomy, although no difference is seen for urinary symptoms or fatigue, role and social functioning scores are higher and there is better post-treatment sexual function in both men and women. Compared with surgical treatment for penile cancer, brachytherapy results in better erectile function scores than after glansectomy and partial penectomy and high quality of life scores, with good satisfaction ratings for cosmetic appearance.

RESUMEN

Introduction: The burden of non-communicable diseases (NCDs) is a major public health concern across the world. Various initiatives have tried to address these with varying degrees of success. Objective: The objective is to assess and collate existing evidence in implementation research done in India on three broad domains of NCDs namely, cardiovascular diseases (CVD), diabetes mellitus (DM), and mental health (MH) in India. Materials and methods: Three systematic review protocols have been drafted to explore and collate extant evidence of implementation research on cardiovascular diseases, diabetes mellitus, and mental health in India, in accordance with the PRISMA-P statement. Academic databases including PubMed, Embase and Science Direct will be searched. Search strategies will be formulated in iterative processes and in accordance with the formats that are specific to the databases that will be searched. In addition, grey literature and non-academic databases will also be explored. Data extracted from the selected studies will be analysed and a narrative summary of the selected articles, using the SWiM (Synthesis without meta-analysis) guidelines will be produced. Intended Outcomes: The outputs of these systematic reviews could help in a better understanding of implementation research gaps and also how to address them. Apart from giving insights into how healthcare initiatives for CVDs, diabetes and mental health could be implemented in a better way, the study could also advocate the need to build and consolidate capacity for implementation research in the country.

RESUMEN

BACKGROUND: Women's education and empowerment are important predictors of contraceptive use across countries. However, two of the Indian states, namely, Punjab and Manipur, showed large variations in contraceptive use, despite the similar level of women's educational attainment and empowerment. Therefore, this paper attempts to understand variation in contraceptive use between these states, despite having similar level of educational attainment and empowerment among the married women. METHODS: This study primarily used cross-sectional data of the National Family Health Survey (NFHS) 2015-16 and to some extent the District Level Household Survey (DLHS) 2012-13 data. The analytical sample includes 13,730 currently married women in Punjab and 8,872 in Manipur. Modern contraceptive prevalence rate (mCPR) is the key outcome variable of this study. Bivariate, multivariate, and multilevel regression analysis are applied to understand the differences in mCPR between these states and its determinants. RESULTS: Mean years of schooling was about 8 years among women of both the states, and about 34% of the women in Punjab and 27% of the women in Manipur have high level of autonomy. Despite this, use of modern method was 66% in Punjab and only 13% in Manipur. Coverage of family planning program indicators were significantly lower in Manipur than Punjab - frontline workers' (FLWs) outreach for family planning was only 18% in Manipur compared to 52% in Punjab. Similarly, only 11% of the public health facilities in Manipur compared to 50% of the health facilities in Punjab were ready to provide at least one clinical method of family planning. CONCLUSION: Despite the similar level of individual level characteristics across the two states, poor coverage of family planning programs - low outreach of FLWs, low level of facility readiness, as well as sociocultural norms discouraging contraceptive use - might be responsible for lower contraceptive use in Manipur than Punjab. This implies for strengthening the health system for family planning in Manipur to meet the contraception needs of women by addressing sociocultural barriers in the state.

RESUMEN

Background & objectives: Sickle cell disease (SCD), an inherited disorder of erythrocytes, is highly prevalent in the tribal population of India. The tribal population of India is approximately 100 million and it is necessary to identify the magnitude of this problem. Furthermore, the prevalence of the disease is unknown among the five million tribal people of southern provinces of Rajasthan. In this study, we intended to determine the prevalence and characteristics of sickle cell disorder among the tribal inhabitants of southern Rajasthan. Methods: This cross-sectional study was conducted among the tribal students of the Maa-Baadis and hostels situated in the five tribal sub-plan districts of Rajasthan. Maa-Baadi centres are located in every village, whereas for every four to five villages, one hostel is allocated to accommodate the tribal students. The screening for SCD was done by solubility test and electrophoresis was used for confirmation. Results: A total of 36,752 tribal students were screened from 1,006 Maa-Baadi centres and 243 hostels. The prevalence of SCD among the tribal students was 5.8 per cent. The prevalence of heterozygous and homozygous conditions was 5.61 and 0.17 per cent, respectively. Among the five sub-plan districts, the highest prevalence was observed in Sirohi district (10.5%) followed by Banswara (7.42%), Udaipur (6.53%), Pratapgarh (5.51%) and Dungarpur (1.89%). Among the four major tribes belonging to these districts, the highest prevalence was recorded in Garasia tribes (13.81%). The history of leg ulcers and the mean pulse rate were significantly high in SCD individuals. Interpretation & conclusions: SCD is a significant problem among the tribes of southern Rajasthan, with the highest prevalence among the Garasia tribe. The present study recommends that a structured screening programme targeting the entire tribal population with appropriate counselling as well as providing treatment through the existing health system is the need of the hour.

RESUMEN

BACKGROUND: Ragi (Eleusine Coracana) is a major food crop for the tribal population of India. OBJECTIVE: This study emphasizes the need to consider ergonomics aspects in the design and development of a pedal operated ragi thresher (PORT) for tribal people, and assesses the drudgery as well as ergonomic evaluation of a developed thresher against the conventional practice. METHODS: Thirty subjects (male = 15 and female = 15) from the tribal region were evaluated ergonomically. The physiological responses of the subjects were studied and their performance was compared. RESULTS: The results revealed that the working heart rate, oxygen consumption rate and overall discomfort rating were significantly higher in case of traditional threshing as compared to those in case of PORT. Postural analysis identified the traditional method as the most fatigue one as the person has to lift the hand above shoulder level repeatedly and has to sit in a squatting posture for long period. CONCLUSION: The drudgery and occupational hazards to public health involved in the traditional method of threshing was reduced by using the PORT. Furthermore, the traditional method involved continuous stressed actions across the entire body, whereas the PORT involved only the lower limbs.

RESUMEN

The role of diketopyrrolopyrrole (DPP-H) as an additive on the ionic conductivity of poly(ethylene oxide) (PEO)-based gel polymer electrolytes (GPE) was studied for DSSC applications. The pure PEO/PC/KI/TPAI/I2 GPE was prepared with a mixture of propylene carbonate (PC) as a non-volatile plasticizer and iodide salts, such as potassium iodide (KI), tetrapropylammonium iodide (TPAI) and iodine (I2), together with PEO. The modified GPEs were prepared with different weight percentage (wt%) ratios (0.5%, 0.75%, 1% and 1.25%) of DPP-H using acetonitrile as a solvent. The polymer gel electrolytes were characterized by X-ray diffractometer (XRD) and Fourier transform infrared spectroscopy (FTIR), and the electrochemical properties were analyzed to relate the nature of the polymer and iodine ion conducting properties. The pure PEO/PC/TPAI/KI/I2 electrolyte exhibited an ionic conductivity value of 0.084 mS·cm-1 at room temperature. Upon the optimized addition of DPP-H (0.75 wt%), the ionic conductivity was found to be improved to a maximum value of 0.393 mS·cm-1, and the highest diffusion coefficient of 1.02 × 10-6 cm2 s-1 was observed. The optimized GPEs photovoltaic characterization studies showed higher power conversion efficiency (PCE) of 6.69% for DSSC under light illumination intensity of 100 mW cm-2. The same was compared with pure electrolyte, which delivered PCE of 4.39%. To gain an in-depth understanding of the interfacial resistance of the fabricated devices, the electron lifetime and transient photo response was analyzed. These above studies showed that prepared GPE could be an efficient alternative for traditional DSSCs with liquid electrolyte.

RESUMEN

BACKGROUND: Linear lesions are fairly common in our daily practice. However, the appearance of these lesions can vary, thus complicating the diagnosis. AIMS: To study the various clinical presentations, the demographic profile of patients and the clinicopathological correlations of dermatoses presenting with a linear distribution. METHODS: We conducted an institution-based, cross-sectional, descriptive study of 281 consecutive patients with linear lesions attending dermatology clinics. MedCalc software (V11.6) was used for statistical analysis. RESULTS: Patients were divided into eight groups: lesions along the lines of Blaschko (n = 136), lesions along blood vessels (n = 3), lesions along lymphatics (n = 3), Koebner phenomenon (n = 24), autoinoculation (n = 24), external factors (n = 45), infestations (n = 2) and 'other' (n = 44). The mean age at presentation was 24.50 ± 18.82 years and the male/female ratio was 1.32 : 1. The commonest symptom was itching/burning (56.94% of patients), while the commonest site was the arm (44.48%); followed by the leg (30.60%), trunk and abdomen (22.42%), head and neck (19.20%), and genitalia (0.35%). Apart from the common cases, there was a wide gamut of rare conditions (e.g. angiokeratoma circumscriptum naeviforme, porokeratotic eccrine ostial and dermal duct naevus, Blaschko-linear syringocystadenoma papilliferum, progressive cribriform and zosteriform hyperpigmentation, unilateral naevoid acanthosis nigricans, fixed drug eruption, discoid lupus erythematosus). CONCLUSION: Linear lesions act as diagnostic clues to many dermatological conditions, therefore, the importance of meticulous examination in clinical dermatology cannot be overemphasized.

RESUMEN

PURPOSE: To analyse factors influencing functional outcome and neurological recovery in patients undergoing delayed surgery for traumatic spinal cord injury (SCI) involving thoracolumbar spine. METHODS: Retrospective analysis of 33 patients with thoracolumbar SCI who underwent delayed surgery (≥ 72hrs post-trauma) with a minimum follow-up of 1 year (average:32.55 months) was done. The parameters studied included age, sex, co-morbidities, mode of trauma, associated trauma, level and number of vertebrae involved, fracture morphology, thoracolumbar injury classification and severity score (TLICS), maximal spinal cord compression (MSCC), signal changes in the cord, neurological deficit as per the American Spinal Injury Association (ASIA) scale, lower extremity motor score (LEMS), bowel bladder involvement, time interval between trauma and surgery. RESULTS: Mean time interval from injury to spine surgery was 24.45 days. At the end of 1-year follow-up, 17(51.5%), 12(36.36%), and 3(9.1%) patients had ≥ 1, ≥ 2, and ≥ 3-grade ASIA improvement, respectively. The mean LEMS rose to 33.86 from 17.09 (P < 0.001). 8 out of 20 patients with bladder involvement showed improvement. 4 patients succumbed, 22 were ambulatory, and 7 remained non-ambulatory. On comparing various parameters, pre-operative LEMS score (P-value: < 0.001), cord signal changes (P-value:0.002), and presence of cord transection (P-value:0.007) differed significantly in the above-mentioned three groups, while age (P-value:0.442), average TLICS (P-value:0.872), time from injury to surgery (P-value:0.386) did not differ significantly. CONCLUSION: This study highlights that there is still a significant scope for neurological improvement even after delayed surgery in patients with thoracolumbar SCI. The lower the LEMS score at the time of presentation, signal changes in the cord and presence of cord transection have a significant influence on unfavourable clinical outcomes at the end of 1-year post-surgery.

RESUMEN

The objective of this study was to describe the authors' long-term experience with the management of odontogenic keratocysts (OKCs). All OKC cases treated at the study centre between 1999 and 2015, with a minimum of 5 years of follow-up by December 2019, were reviewed retrospectively. Operative procedures including decompression/marsupialization, enucleation (E), E+Carnoy's solution (CS), E+CS+peripheral ostectomy (PO), and resection were assessed for complete resolution, partial resolution, and recurrence rates. In the parakeratinized non-syndromic group, E+CS+PO resulted in the lowest recurrence rate among the minimally invasive procedures (4.3%), while enucleation resulted in the highest rate (60%). Regarding the other modalities, recurrence was 12.5% for decompression, 11.5% for marsupialization, 16.7% for E+CS, 26.7% for E+PO, and 0% for resection. In the syndromic group, marsupialization resulted in a significantly higher recurrence (23.1%), while E+CS+PO cases showed no recurrence. No recurrence was observed in the orthokeratinized group patients treated with marsupialization or with E+CS. Based on clinico-radiographic features and observed results, it is concluded that OKC, although having a high recurrence rate, is a benign lesion and responds well to conservative procedures in most cases. Radical procedures should be reserved for unresponsive lesions and those with extensive tissue destruction.

RESUMEN

We designed this study to determine the efficiency and stability of anterior segmental osteotomies (ASO) without orthodontics for various dentofacial deformities. Records of patients treated with maxillary or mandibular ASO, or both, without orthodontics in the past 15 years were analysed. The assessment included postoperative analysis of patients' aesthetics and functional satisfaction using a questionnaire and grading (score 0 - 4) system, and the amount of relapse calculated from 12-month postoperative cephalograms. A total of 26 ASO subjects (age range 13- 31 years) were studied (14 maxillary, two mandibular, and 10 bimaxillary). Long-term stability was acceptable in all cases with no significant relapse (p>0.05). No major complications were encountered. All patients reported good to excellent (score=3 to 4) satisfaction following surgery. Using meticulous planning and a careful surgical technique, ASO without orthodontics is a simple, quick, safe, and stable option for the correction of dentofacial deformities.

RESUMEN

BACKGROUND: The World Health Organization (WHO) has endorsed the next-generation Xpert MTB/RIF Ultra (Ultra) cartridge, and Uganda is currently transitioning from the older generation Xpert MTB/RIF (Xpert) cartridge to Ultra as the initial diagnostic test for pulmonary tuberculosis (TB). We assessed the diagnostic accuracy of Ultra for pulmonary TB among adults in Kampala, Uganda. METHODS: We sampled adults referred for Xpert testing at two hospitals and a health center over a 12-month period. We enrolled adults with positive Xpert and a random 1:1 sample with negative Xpert results. Expectorated sputum was collected for Ultra, and for solid and liquid culture testing for Xpert-negative patients. We measured sensitivity and specificity of Ultra overall and by HIV status, prior history of TB, and hospitalization, in reference to Xpert and culture results. We also assessed how classification of results in the new "trace" category affects Ultra accuracy. RESULTS: Among 698 participants included, 211 (30%) were HIV-positive and 336 (48%) had TB. The sensitivity of Ultra was 90.5% (95% CI 86.8-93.4) and specificity was 98.1% (95% CI 96.1-99.2). There were no significant differences in sensitivity and specificity by HIV status, prior history of TB or hospitalization. Xpert and Ultra results were concordant in 670 (96%) participants, with Ultra having a small reduction in specificity (difference 1.9, 95% CI 0.2 to 3.6, p=0.01). When "trace" results were considered positive for all patients, sensitivity increased by 2.1% (95% CI 0.3 to 3.9, p=0.01) without a significant reduction in specificity (- 0.8, 95% CI - 0.3 to 2.0, p=0.08). CONCLUSIONS: After 1 year of implementation, Ultra had similar performance to Xpert. Considering "trace" results to be positive in all patients increased case detection without significant loss of specificity. Longitudinal studies are needed to compare the benefit of greater diagnoses to the cost of overtreatment.

RESUMEN

PURPOSE: To determine the association between coronal Cobb's angle and Nash-Moe index in patients with adolescent idiopathic scoliosis. We also attempted to determine whether apical vertebral derotation depended upon the curve flexibility. OVERVIEW OF LITERATURE: The three-dimensional nature of adolescent idiopathic scoliosis (AIS) is well established. Knowledge of all components of this complex deformity is essential to formulate effective treatment strategies. Though the importance of quantifying all the components of the deformity, in AIS, has been analysed in detail, very few studies have been done to ascertain the relationship between the coronal plane deformity and apical vertebral rotation. METHODS: Digitalised standing and supine stretch anteroposterior (AP) radiographs of 158 patients with AIS were analysed. The standing and supine stretch AP radiographs were compared to calculate the percentage reduction of Cobb's angle to determine curve flexibility. The derotation of the apical vertebra on application of traction was also noted. The one-way repeated ANOVA was used to determine the association between Cobb's angle and Nash-Moe index. The independent sample t test was used to determine whether a statistically significant difference was present, in the age of the patient, severity of the curve and percentage reduction of Cobb's angle between those curves that derotated and those that did not, when stretched. RESULTS: The one-way repeated ANOVA revealed an association between Cobb's angle and Nash-Moe index on the standing and supine AP stretch radiographs (P < 0.01). The Independent sample t-test showed a statistically significant difference in percentage reduction of Cobb's angle between those curves that derotated compared to those that did not, on stretch (P < 0.01). CONCLUSIONS: This study demonstrates that there is an association between apical vertebral rotation and the coronal plane deformity. It also demonstrates that flexible curves derotate to a greater extent compared to rigid curves, when stretched.

RESUMEN

Introduction: Elbow dislocation usually presents with a deformity and swelling, yet it can also present with neurological complication. Nerve injury with dislocation is common in the pediatric age group and is reported infrequently among adults. The most common nerve involved with dislocation is the ulnar nerve followed by the median nerve. The median nerve usually slips medially during dislocation and gets entrapped posterior to the medial epicondyle or it can get entrapped between the fractured medial epicondyle. Here, we describe a unique case of posterolateral elbow dislocation in a 30-year-old female patient with having lateral displacement of the median nerve and the mechanism probably by which the nerve got displaced laterally. Case Presentation: A 30-years-old female patient of right hand dominant came to us with a left elbow injury after a road traffic accident. Clinical and Radiological examination revealed a posterior-lateral dislocated elbow with a fracture of the radial head and lateral condyle avulsion. Clinically, there was a weakness and sensory hypoesthesia along the median nerve distribution over the left hand and forearm. Initially, closed reduction and splinting done. Later, a planned surgery with a lateral approach avulsed lateral condyle and radial head fixation done with relocation of the median nerve, which was displaced laterally. Conclusion: There are numerous cases of elbow dislocation with nerve involvement and their complications have been previously described throughout literature. Here, we present a rare case of lateral displacement of the median nerve in a dislocated elbow and the possible mechanism with its management.

RESUMEN

Among new smear-positive pulmonary tuberculosis (TB) patients aged ⩾15 years from marginalised populations in India, one in four had a history of a household member with TB and one in 10 had a TB-related death in the household. This contribution of household transmission to overall TB transmission provides evidence for a potential population-level benefit of TB preventive treatment for all household contacts (without active TB). Females with TB had a significantly higher household TB exposure than males. Targeted TB preventive treatment (if implemented in a phased manner) among female household contacts may be explored after considering other factors.


Parmi les nouveaux cas de tuberculose (TB) pulmonaire confirmés par bactériologie de patients (⩾15 ans) de populations marginalisées en Inde, un quart avait eu un membre du foyer atteint de TB et un sur 10, un décès dû à la TB au sein du foyer. La contribution de la transmission domiciliaire à l'ensemble de la transmission de la TB est en faveur d'un bénéfice potentiel pour la population, du traitement préventif de la TB pour tous les membres du foyer (sans TB active). Les patients TB de sexe féminin ont une exposition domiciliaire à la TB significativement plus élevée que les hommes. Un traitement préventif de la TB ciblé (s'il est mis en œuvre par phases) sur les contacts féminins du foyer pourrait être évalué après avoir tenu compte des autres facteurs.
