RESUMO
Workplace violence is a major occupational issue concerning doctors that has a significant impact on their physical and psychological well-being. This ultimately affects the health care services of the country. Patient-led episodes of verbal violence are more prevalent in Asian countries, especially in the emergency department, psychiatric wards, and intensive care units, mostly faced by junior doctors and residents. Some common precursors of violence against doctors are patients and their attendants' dissatisfaction and low impulse control, poor administration, miscommunication, infrastructural issues especially differences in services between private and public hospitals, and negative media portrayal of doctors. The assessment of risk factors, development and implementation of workplace violence programs, and addressing underreporting of violent episodes have been suggested as some successful organizational mitigation strategies. Recommendations on the management of workplace violence include the development of participative, gender-based, culture-based, nondiscriminatory, and systematic strategies to deal with issues related to violence. This article aims to present a comprehensive review of workplace violence against doctors, discussing the prevalence, degree of violence, predictors, impact on physical and psychological health and intervention strategies to devise practical actions against workplace violence.

PURPOSE: To evaluate the safety and efficacy of OTX-101, a novel aqueous nanomicellar formulation of cyclosporine (0.09%), in the treatment of patients with dry eye disease (DED). DESIGN: A randomized, multicenter, vehicle-controlled, double-masked, phase 3 clinical trial. PARTICIPANTS: Adults (18-90 years of age) with a history and clinical diagnosis of DED, a global symptom score of 40 or more (range, 0-100), and a lissamine green conjunctival staining score of 3 or more and 9 or less (range, 0-12) in at least 1 eye. METHODS: Eligible patients entered a run-in period of 14 to 20 days in which all patients administered vehicle twice daily. Patients who remained eligible at the baseline (day 0) visit were randomized in a 1:1 ratio to twice-daily treatment with OTX-101 0.09% or vehicle for 84 days. MAIN OUTCOME MEASURES: Efficacy assessments included signs (unanesthetized Schirmer tear test, corneal and conjunctival staining) and symptoms (global symptom score) of DED. The primary end point was the proportion of eyes with a clinically meaningful improvement (increase of ≥10 mm) in Schirmer test score at day 84. Safety evaluations included adverse events (AEs), visual acuity, and intraocular pressure monitoring, slit-lamp, dilated ophthalmoscopy, and fundus examinations. RESULTS: A total of 744 patients were randomized and received study medication (371 to OTX-101 0.09% and 373 to vehicle). The primary end point was achieved; a significantly greater percentage of eyes in the OTX-101 0.09% treatment group achieved an increase of 10 mm or more in the Schirmer test score at day 84 (OTX-101 0.09%, 16.6%; vehicle, 9.2%; P < 0.001). Significant improvements relative to vehicle also were observed for corneal (days 28, 56, and 84) and conjunctival (days 56 and 84) staining. The global symptom score was reduced from baseline in both treatment groups by approximately 30%; however, no significant separation between groups was observed. The OTX-101 0.09% formulation was well tolerated. Treatment-emergent AEs were primarily mild in intensity. CONCLUSIONS: Clinically and statistically significant improvements in tear production and ocular surface integrity were observed in patients treated with OTX-101 0.09% for DED.

Dysfunctional tear syndrome (DTS) is a common and complex condition affecting the ocular surface. The health and normal functioning of the ocular surface is dependent on a stable and sufficient tear film. Clinician awareness of conditions affecting the ocular surface has increased in recent years because of expanded research and the publication of diagnosis and treatment guidelines pertaining to disorders resulting in DTS, including the Delphi panel treatment recommendations for DTS (2006), the International Dry Eye Workshop (DEWS) (2007), the Meibomian Gland Dysfunction (MGD) Workshop (2011), and the updated Preferred Practice Pattern guidelines from the American Academy of Ophthalmology pertaining to dry eye and blepharitis (2013). Since the publication of the existing guidelines, new diagnostic techniques and treatment options that provide an opportunity for better management of patients have become available. Clinicians are now able to access a wealth of information that can help them obtain a differential diagnosis and treatment approach for patients presenting with DTS. This review provides a practical and directed approach to the diagnosis and treatment of patients with DTS, emphasizing treatment that is tailored to the specific disease subtype as well as the severity of the condition.

Though demonstration of Plasmodium parasite in peripheral blood on microscopy remains gold standard, it may miss some patients resulting in delay in instituting life-saving therapy. Studies on polymerase chain reaction (PCR), a highly sensitive and specific technique that also discriminates among different species of malaria parasite, are scanty. Hence, we aimed to evaluate the role of PCR in diagnosis and species identification of Plasmodium. Of 2186 febrile patients with clinical suspicion of malaria screened between July 2013 to February 2015, 561 patients fulfilled inclusion criteria. Microscopy, rapid diagnostic test (RDT) and PCR were performed to identify the parasite. Plasmodium was detected in 64/561 (11.40 %), 92/561 (16.40 %) and 78/561 (13.90 %) cases using microscopy, RDT and PCR, respectively. Of 78 positive cases by PCR, 47 (60.25 %) were confirmed as Plasmodium falciparum (P. falciparum), 28 (35.89 %) were Plasmodium vivax (P. vivax) and 3 (3.84 %) had mixed infections. Sensitivity and specificity of microscopy and RDT were 82.10 %, 100 % and 98.70 %, 96.90 %, respectively (p = 0.139). Of total 93 patients, 67 (72.04 %) were classified as complicated and 26 (27.96 %) were as uncomplicated. Creatinine (p = <0.001), conjugated bilirubin (p = 0.003) and total bilirubin (p = <0.001) level was elevated in complicated malaria along with renal (65 %) and liver dysfunction (25 %). In the present study, P. falciparum was responsible for 40/67 (59.70 %) cases of complicated malaria; P. vivax was also found in 17/67 (25.37 %) complicated cases using PCR. The findings highlight the alarming number of complicated vivax malaria in addition to falciparum. Moreover, PCR proved to be highly sensitive and specific test for detecting Plasmodium species.

UNLABELLED: Hypoxia inducible factors (HIFs) are activated in many tumors and show either promoter or suppressor activity, depending on tumor cell biology and background. However, the role of HIF member HIF-2α remains unclear in hepatocellular carcinoma (HCC). Here, HIF-2α expression was measured in HCC and paired peritumoral tissues by quantitative real-time polymerase chain reaction, western blotting, and immunofluorescence assays, and the clinical significance was explored in 246 HCC patients. In cell culture, HIF-2α levels were up-regulated or down-regulated by use of expression or short hairpin RNA recombinant plasmid, respectively. Cells were analyzed by immunoblotting, chromatin immunoprecipitation coupled with microarray, coimmunoprecipitation, and immunohistochemical staining. In vivo tumor growth was analyzed in nude mice. We found that the average expression of HIF-2α was relatively low in HCC tissues, and the decreased level was associated with lower overall survival (P=0.006). High HIF-2α expression in HCC cells induced higher levels of apoptosis and expression of proapoptotic proteins and inhibited cell and tumor growth. Furthermore, HIF-2α inhibited expression of the novel target gene, transcription factor dimerization partner 3 (TFDP3). TFDP3 protein was found to bind with E2F transcription factor 1 (E2F1) and inhibit its transcriptional activity through both p53-dependent and -independent pathways. Reintroduction of TFDP3 expression reversed HIF-2α-induced apoptosis. CONCLUSIONS: Data gathered from cell lines, tumorigenicity studies, and primary HCC samples demonstrate a negative role of HIF-2α in tumors, which is mediated by the TFDP3/E2F1 pathway. Our study provides evidence supporting a possible tumor-suppressor role for HIF-2α and has uncovered a mechanism that links HIF-2α to a fundamental biological regulator, E2F1.

This study evaluated the effects of a standardized ethyl acetate extract of Morinda citrifolia L. (Noni) fruit on impairment of memory, brain energy metabolism, and cholinergic function in intracerebral streptozotocin (STZ)-treated mice. STZ (0.5 mg/kg) was administered twice at an interval of 48 h. Noni (50 and 100 mg/kg, postoperatively) was administered for 21 days following STZ administration. Memory function was evaluated using Morris Water Maze and passive avoidance tests, and brain levels of cholinergic function, oxidative stress, energy metabolism, and brain-derived neurotrophic factor (BDNF) were estimated. STZ caused memory impairment in Morris Water Maze and passive avoidance tests along with reduced brain levels of ATP, BDNF, and acetylcholine and increased acetylcholinesterase activity and oxidative stress. Treatment with Noni extract (100 mg/kg) prevented the STZ-induced memory impairment in both behavioral tests along with reduced oxidative stress and acetylcholinesterase activity, and increased brain levels of BDNF, acetylcholine, and ATP level. The study shows the beneficial effects of Noni fruit against STZ-induced memory impairment, which may be attributed to improved brain energy metabolism, cholinergic neurotransmission, BDNF, and antioxidative action.

Constitutional chromosomal aberrations contribute to infertility and repeated miscarriage leading to reproductive failure in couples. These aberrations may show no obvious clinical manifestations and remain undetected across multiple generations. However, infertility or recurrent spontaneous pregnancy loss, and/or genotypic/phenotypic aberrations may be manifested in the progeny during gametogenesis. The current study was a retrospective analysis to examine the chromosomal aberrations and prevalence in 2000 couples of Indian ethnicity with reproductive failure. Cytogenetic analysis via conventional G-band karyotyping analysis was carried out on phytohaemagglutinin stimulated peripheral blood lymphocytes, cultured in RPMI1640 medium. The chromosomes were enumerated as per International System for Human Cytogenetic Nomenclature at 500-550 band resolution, and recorded in the screening sheets. Chromosomal aberrations were detected in a total of 110 (2.78%) couples, with structural chromosomal aberrations in 88 cases including reciprocal translocations in 56 cases, Robertsonian translocations in 16 cases, inversions in eight cases, deletions in three cases, derivative chromosomes in five cases and numerical chromosome aberrations in 23 cases. The study emphasizes the importance of cytogenetic work up in both the partners associated with a history of reproductive failure. Genetic counselling with an option of prenatal diagnosis should be offered to couples with chromosomal aberrations.

BACKGROUND: Influenza A (H1N1) hit the headlines in recent times and created mass hysteria and general panic. The high cost and non-availability of diagnostic laboratory tests for swine flu, especially in the developing countries underlines the need of having a cheaper, easily available, yet reasonably accurate screening test. AIMS: This study was carried out to develop a clinical feature-based scoring system (CFSS) for influenza A (H1N1) and to evaluate its suitability as a screening tool when large numbers of influenza-like illness cases are suspect. SETTINGS AND DESIGN: Clinical-record based study, carried out retrospectively in post-pandemic period on subject's case-sheets who had been quarantined at IG International Airport's quarantine center at Delhi. MATERIALS AND METHODS: Clinical scoring of each suspected case was done by studying their case record sheet and compared with the results of RT-PCR. RT-PCR was used to confirm the diagnosis (Gold Standard). STATISTICAL ANALYSIS: We calculated sensitivity, specificity, positive and negative predictive values of the clinical feature-based scoring system (the proposed new screening tool) at different cut-off values. The most discriminant cut-off value was determined by plotting the ROC curve. RESULTS: Of the 638 suspected cases, 127 (20%) were confirmed to have H1N1 by RT-PCR examination. On the basis of ROC, the most discriminant clinical feature score for diagnosing Influenza A was found to be 7, which yielded sensitivity, specificity, positive, and negative predictive values of 86%, 88%, 64%, and 96%, respectively. CONCLUSION: The clinical features scoring system (CFSS) can be used as a valid and cost-effective tool for screening swine flu (influenza A (H1N1)) cases from large number of influenza-like illness suspects.

Periodontitis, a multiple pathogen disease has the latest addition to the family i.e. Escherichia coli as a potential and emerging periodontal pathogen owing to its lipopolysaccharide more potent than Porphyromonas gingivalis, which makes it an emerging threat in periodontal disease. The role of antimicrobial agents in the management of periodontal diseases is of utmost importance. However, in the present scenario, antibiotic resistance is a public health concern now and there are very few options left for treatment. So, honey, a pioneer in traditional medicine was tried in the treatment against Escherichia coli to evaluate and compare the "in-vitro" antibacterial activity and efficacy of raw and commercial honey at different concentrations in comparison to tetracycline as a control on patient-isolated Escherichia coli and the American Type Culture Collection (ATCC) Escherichia coli 25922 strain from 5th Aug 2018 to 15th Feb 2019 at the Department of Microbiology, Rama Medical College, Kanpur (UP), India. In the in-vitro study different concentrations (100%, 75%, 50% and 25% v/v) of raw and commercial honey were studied and sensitivity tests were used to evaluate their antibacterial effect on patient-isolated Escherichia coli and the ATCC Escherichia coli 25922 strain. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) were also determined for raw honey, and commercial honey in comparison to tetracycline. In case of raw honey, zone of inhibition was seen at 100%, 75% and 50% concentration, with maximum inhibition being 27±1.154mm and 23±0.666mm for patient-isolated Escherichia coli and ATCC Escherichia coli 25922 strain respectively at 100% concentration, whereas, the commercial honey was effective only at 100% and 75% concentration, with maximum inhibition zone of 13±1.054mm and 17±0.942mm at 100% concentration on patient-isolated Escherichia coli and ATCC Escherichia coli 25922 strain respectively. However, no effect was observed at 25% concentration for both raw and commercial honey. The MIC and MBC of raw and commercial honey were determined by the broth dilution method, where raw honey exhibited both MIC and MBC at 512 mg/ml whereas, and commercial honey exhibited MIC at 512mg/ml and MBC at 1024 mg/ml respectively. While comparing the zone of inhibition of raw and commercial honey, it was observed that the raw honey showed almost equivalent potency and efficacy as compared to a positive control tetracycline (2.5%). There was statistically significant difference (p≤0.01) in zone of inhibition of raw and commercial honey at 100% concentration on patient-isolated Escherichia coli and ATCC Escherichia coli 25922 strain. Antimicrobial activity of raw honey at 100% concentration was equivalent to that of tetracycline and was significantly better than commercial honey.

AIM: To highlight an increased incidence of colorectal cancer (CRC) amongst young Indian adults. METHOD: A retrospective study of 305 cases of CRC admitted to SSKM Hospital, Kolkata, India during 2000-2008 was carried out. RESULTS: The ratio (0.64) of under-40 to above-40 CRC patients reported in this study is comparable to those from premier Oncology Centers in India (â¼0.52) and is higher than those in the Indian National Cancer Registry (â¼0.20) and international average (0.07). Distinctive tumour characteristics in younger patients including left-sided lesion (69.7%), presentation at an advanced (III/IV) stage (60%), poor histological differentiation (50%) and predominance of mucin-secreting adenocarcinoma (80%) are similar to those reported in the international literature. Some features are suggestive of hereditary non polyposis colorectal cancer syndrome, which may be a possible reason for the high proportion of young CRC patients. CONCLUSION: A high index of suspicion for CRC among young Indian adults is necessary.

PURPOSE: The studies reported here aimed to assess the safety and tolerability of cetirizine ophthalmic solution 0.24%, a new topical ophthalmic medication approved by the US Food and Drug Administration for the treatment of ocular itching associated with allergic conjunctivitis. PATIENTS AND METHODS: Three clinical studies evaluated cetirizine ophthalmic solution 0.24% administration: a Phase I prospective, single-center, open-label, pharmacokinetic (PK) study (N=11) evaluating single-dose administration and twice-daily (BID) administration for 1 week in healthy adults, and two Phase III, multi-center, randomized, double-masked, vehicle-controlled, parallel-group studies evaluating the safety and tolerability in adult and pediatric populations (2-18 years of age) for up to 6 consecutive weeks. The first safety and tolerability study evaluated cetirizine BID (study 1, N=512), while the second study examined cetirizine three times daily (TID) (study 2, N=516). Each study assessed best corrected visual acuity, slit-lamp biomicroscopy, IOP, dilated ophthalmoscopy, treatment-emergent adverse events, vital signs, urine pregnancy test, and physical examination (general health, head, eyes, ears, nose, and throat). The PK study also measured hematology, blood chemistry, and urinalysis, while the two Phase III studies additionally assessed corneal endothelial cell counts (ECC) and ECC density in a subset of subjects (via specular microscopy), and drug administration tolerability. RESULTS: Bilateral administration of cetirizine ophthalmic solution 0.24% resulted in low systemic exposure in the PK study and was associated with a low incidence of mild adverse events. There were no drug-related severe or serious adverse events. The tolerability scores between the active and vehicle groups were comparable, demonstrating high comfort in the administration of cetirizine ophthalmic solution 0.24%. CONCLUSION: Cetirizine ophthalmic solution 0.24% dosed BID or TID demonstrated an acceptable safety profile and was well-tolerated when administered to subjects aged ≥2 years.
RESUMO
There is paucity of studies on predictors of long-term sequelae of tuberculous meningitis (TBM). We report the neurological sequelae of TBM at 1 year and their predictors. Patients with TBM who were followed up for 1 year were included. The diagnosis of TBM was based on clinical, cerebrospinal fluid (CSF) and computed tomography (CT) scan findings. Detailed neurological examinations at admission and at 1 year were carried out. All the patients received four-drug antitubercular therapy. The frequency of sequelae at 1 year were noted and the role of various demographic (age, sex, duration of illness, BCG vaccination), clinical (weakness, seizure, extra central nervous system tuberculosis, Glasgow Coma Scale (GCS) score, cranial nerve palsy, stage, corticosteroid, drug-induced hepatitis, shunt surgery), and laboratory findings (erythrocyte sedimentation rate (ESR), CSF cell and protein, CT scan evidences of hydrocephalus, basal exudates, infarctions and tuberculoma) at presentation were evaluated employing logistic regression analysis. Sixty-five patients with TBM were included in this study whose age ranged between 13 and 80 years (mean 33.2), 27 of whom were females. Complete neurological recovery at 1 year occurred in 21.5% patients only although about 50% were independent for activities of daily living. Neurological sequelae were observed in 78.5% patients, which included cognitive impairment in 55%, motor deficit in 40%, optic atrophy in 37% and other cranial nerve palsy in 23%. On logistic regression analysis, focal motor deficit at admission was the most important predictor of neurologic deficits at 1 year. GCS score predicted the cognitive and motor sequelae. Neurological sequelae at year occurred in 78.5% patients with TBM in the form of cognitive impairment, motor deficit and optic atrophy. Sequelae were common in patients who had focal motor deficit and altered sensorium at admission.

Traditional examination has inherent deficiencies. Objective Structured Clinical Examination (OSCE) is considered as a method of assessment that may overcome many such deficits. OSCE is being increasingly used worldwide in various medical specialities for formative and summative assessment. Although it is being used in various disciplines in our country as well, its use in the stream of general surgery is scarce. We report our experience of assessment of undergraduate students appearing in their pre-professional examination in the subject of general surgery by conducting OSCE. In our experience, OSCE was considered a better assessment tool as compared to the traditional method of examination by both faculty and students and is acceptable to students and faculty alike. Conducting OSCE is feasible for assessment of students of general surgery.
RESUMO
PURPOSE: Enteric parasitic infestation is a major public health problem in developing countries. Parasites such as Cryptosporidium spp., Cyclospora spp., Cystoisospora spp. and Microsporidia may cause severe diarrhoea among immunocompromised patients. There is scanty data on their frequency among immunocompetent patients. Accordingly, we studied the frequency of enteric opportunistic parasites among immunocompetent patients with diarrhoea from northern India; we also performed genetic characterisation of Cryptosporidia and Microsporidia among them. PATIENTS AND METHODS: Stool samples from 80 immunocompetent patients with diarrhoea, and 110 healthy controls were examined. Parasites were detected by direct microscopy, modified acid-fast (Kinyoun's) and modified trichrome stain. Polymerase chain reaction--restriction fragment length polymorphism was used for genetic characterisation of selected species such as Cryptosporidia and Microsporidia. RESULTS: Enteric parasites were detected in 16/80 (20%) patients (mean age 28.8±20 years, 45, 56% males) and in 2/110 (1.8%) healthy controls (P=0.00007). Parasites detected were Cryptosporidium spp. (8/16, 50.0%), Cystoisospora spp. (4/16, 25%), Microsporidia (1/16, 6.25%), Cyclospora spp. (1/16, 6.25%) and Giardia spp. (1/16, 6.25%). One patient had mixed infection with Cystoisospora spp. and Giardia spp. The species of Cryptosporidia and Microsporidia detected were Cryptosporidium hominis and Enterocytozoon bieneusi, respectively. Parasites were more often detected in younger patients (≤20 years of age) than in older. Most of the parasite infected patients presented with chronic diarrhoea. CONCLUSION: Opportunistic enteric parasitic infestation was more common among immunocompetent patients with diarrhoea than healthy subjects. Special staining as well as molecular methods are essential for appropriate diagnosis of these parasites.

BACKGROUND: Polymorphisms of the IL28B gene (rs12979860 and rs8099917) have been shown to impact treatment responses in hepatitis C virus (HCV) infected patients. The association of these polymorphisms with sustained viral response (SVR) has been studied in HCV genotype 3 infected patients in India, but not in genotype 1. OBJECTIVES: This study aimed to determine the association of IL28B gene polymorphisms and other host and viral factors with treatment response in patients with HCV genotype 1 and 3 infection. MATERIALS AND METHODS: DNA from 42 HCV-infected patients on antiviral therapy was analysed for the IL28B polymorphisms using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Bidirectional sequencing was performed on a subset of samples for verification of PCR-RFLP results. Information on age, weight, height, diabetic status, pre-treatment viral load and alanine aminotransferase (ALT) levels was obtained from clinical records. The IL28B genotypes and the other factors were analysed for their association with SVR. RESULTS: The frequency distribution of rs12979860 CC/CT/TT genotypes was found to be 66.7%, 26.2% and 7.1%, respectively. For rs8099917 genotype, the TT/GT/GG distribution was 73.8%, 21.4% and 4.8%, respectively. SVR was seen in 61.9% of cases (55.6% in genotype 1 and 62.5% in genotype 3). CC genotype at rs12979860 and TT genotype at rs8099917 were significantly higher in responders (P = 0.013 and 0.042, respectively). Lower baseline ALT and rapid viral response were also found to be associated with SVR. On logistic regression analysis, CC genotype at rs12979860 emerged as the most powerful predictor of treatment response. CONCLUSION: IL28B polymorphisms are strong predictors of SVR in patients from the Indian subcontinent infected with HCV genotype 3 and genotype 1.

OBJECTIVE: To study the usefulness of mannitol in spontaneous intracerebral hemorrhage (ICH) patients. METHOD: 128 CT proven supratentorial ICH patients within 6 days of ictus were randomized into study and control groups. The study group received mannitol 20%, 100 ml every 4 h for 5 days, tapered in the next 2 days. The control group received sham infusion. Primary endpoint was 1-month mortality and secondary endpoint functional disability at 3 months assessed by Barthel index score. RESULTS: There were 65 patients in study and 63 in control groups. The study and control groups were evenly matched regarding age, Glasgow coma scale (GCS) score, Canadian Neurological Scale (CNS) score, pupillary asymmetry, pyramidal signs on non-hemiplegic side, and location, midline shift and ventricular extension of hematoma. At 1 month, 16 patients died in each group. The primary and secondary endpoints were not significantly different between the two groups. CONCLUSION: Low dose mannitol does not seem to be beneficial in patients with ICH.

Linear acantholytic dermatoses are a spectrum of cutaneous disorders that form a subset of linear dermatoses with distinct clinical features and histopathologically show acantholysis. The lesions may be zosteriform or follow the lines of Blaschko. This report describes a four-year-old boy who, on a follow up of two years, exhibited a relapsing acantholytic dermatosis along the lines of Blaschko. Histopathology of a representative lesion revealed epidermal acantholysis with multiple acantholytic keratinocytes with in the prickle cell layer and an absence of corp ronds and grains, consistent with features of Hailey-Hailey disease. This, to our knowledge, is the third case of relapsing linear acantholytic dermatosis reported.
