RESUMEN
BACKGROUND: TB preventative therapy (TPT) is crucial for reducing the burden of TB in endemic settings. We assessed stigma associated with TPT and the social groups from whom stigma was anticipated.METHODS: We conducted an anonymous cross-sectional survey of community-dwelling adults in rural South Africa. Descriptive statistics, exploratory factor analysis, χ² tests, Kruskal-Wallis tests, and Poisson regression were used to identify factors associated with TPT stigma.RESULTS: The mean age of the 104 participants was 35 years, 65% were female, and 26% had completed secondary school. The vast majority perceived stigma associated with TPT (71%; mean score 1.7, SD ± 1.4). Factor analysis identified a two-factor solution that explained 61.9% of the variance. Being single (P < 0.001), previously screened for TB (P = 0.04), worried about being infected by TB (P = 0.006), and interested in taking TPT (P = 0.01) were associated with higher perceived stigma scores. TPT stigma was perceived among 8%, 16%, and 66% of their family, friends, and other community members, respectively.CONCLUSION: The prevalence of TPT-related stigma in a rural South African community was high. Community members anticipated less stigma from family members compared to other social groups. Global expansion and implementation of TPT will require novel interventions, such as engaging patients´ families to support uptake and promote adherence.

Purpose: "The purpose of the study is to evaluate alveolar ridge split and expansion (ARSE) with simultaneous implant placement in mandibular posterior implant sites using motorized ridge expanders." Background: The ARSE is used in the management of horizontally deficient (narrow) alveolar ridge with optimum bone height available. The ARSE procedure in the posterior mandible has limited application as per literature. The successful cases reported are with extensive procedure of the osteo-mobilization with four corticotomies on buccal side. The authors presented the study of mandibular posterior implant sites using motorized ridge expanders. The ARSE performed here was by only crestal osteotomy simple osteo-condensation and immediate implant insertion. Materials and Methods: The study was prospective type. The sample size was 15 patients and 31 implant sites. The study population included partially edentulous patients between 18 years and 60 years indicated for implant-supported prosthesis. The outcome variables studied included gain in ridge width, cervical bone loss, success of implant, and survival rate. Successful surgical outcome was evaluated by Buser's criteria. The data collected was evaluated by differential statistics. Conclusion: The minimally invasive technique of one-stage ARSE performed with motorized ridge expander and insertion of implant in the same operative procedure decreases the morbidity, treatment time, number of surgical procedures, and the risk of complications, thereby, increasing patient acceptance. In this study, the authors have used this technique in the posterior mandible for narrow ridges (minimum 3 mm) and obtained promising results. The survival rate of the implants was 100% and the gain in ridge width was 3.2 mm. The author has also recommended the protocol according to bone density of mandible.
RESUMEN
Non-invasive biomarkers will enable widespread screening and early diagnosis of Alzheimer's disease (AD). We hypothesized that the considerable loss of brain tissue in AD will result in detection of brain lipid components in urine, and that these will change in concert with CSF and brain biomarkers of AD. We examined urine dicarboxylic acids (DCA) of carbon length 3-10 to reflect products of oxidative damage and energy generation or balance that may account for changes in brain function in AD. Mean C4-C5 DCAs were lower and mean C7-C10 DCAs were higher in the urine from AD compared to cognitively healthy (CH) individuals. Moreover, mean C4-C5 DCAs were lower and mean C7-C9 were higher in urine from CH individuals with abnormal compared to normal CSF amyloid and Tau levels; i.e., the apparent urine changes in AD also appeared to be present in CH individuals that have CSF risk factors of early AD pathology. In examining the relationship between urine DCAs and AD biomarkers, we found short chain DCAs positively correlated with CSF Aß42, while C7-C10 DCAs negatively correlated with CSF Aß42 and positively correlated with CSF Tau levels. Furthermore, we found a negative correlation of C7-C10 DCAs with hippocampal volume (p < 0.01), which was not found in the occipital volume. Urine measures of DCAs have an 82% ability to predict cognitively healthy participants with normal CSF amyloid/Tau. These data suggest that urine measures of increased lipoxidation and dysfunctional energy balance reflect early AD pathology from brain and CSF biomarkers. Measures of urine DCAs may contribute to personalized healthcare by indicating AD pathology and may be utilized to explore population wellness or monitor the efficacy of therapies in clinical trials.

Changes in sea level may be attributed either to barotropic (involving the entire water column) or baroclinic processes (governed by stratification). It has been widely accepted that barotropic sea level changes in the tropics are insignificant at intraseasonal time scales (periods of 30-80 days). Based on bottom pressure records, we present evidence for significant basin-wide barotropic sea level variability in the tropical Indian Ocean during December-April with standard deviations amounting to â¼30-60% of the standard deviation in total intraseasonal sea level variability. The origin of this variability is linked to a small patch of wind over the Eastern Indian Ocean, associated with boreal winter Madden-Julian Oscillations (MJO). These large fluctuations are likely to play a prominent role in the intraseasonal sea level and mass budgets. Because of their much faster propagation than baroclinic processes, they allow the basin to adjust to climatic perturbations much more rapidly than was previously thought.
RESUMEN
SETTING: Community health screenings in KwaZulu-Natal Province, South Africa. OBJECTIVE: To study the synergism between diabetes mellitus (DM) and human immunodeficiency virus (HIV) infection in increasing the risk of tuberculosis (TB). DESIGN: In this cross-sectional study, we analyzed data from two community health projects, one at congregate settings, and one at household settings (n = 7708), in a rural resource-limited region where integrated communicable and non-communicable disease screening services were offered. Odds ratios (ORs) for demographic factors, socio-economic factors, DM status, and HIV positivity were calculated using multivariate analysis, and the statistical interaction between HIV and DM was tested. The primary outcome was the presence of TB symptoms. RESULTS: Among 7708 individuals, age >65 years (OR 1.72, 95%CI 1.47-2.02), HIV infection (OR 1.66, 95%CI 1.40-1.97) and DM (OR 1.36, 95%CI 1.11-1.67) were independently associated with increased odds of TB symptoms. Receiving monthly grants (OR 0.78, 95%CI 0.66-0.91), access to a toilet (OR 0.54, 95%CI 0.35-0.83), and access to solar or electric energy (OR 0.86, 95%CI 0.77-0.97) reduced the odds. There was evidence of significant interaction between DM and HIV on the multiplicative scale. CONCLUSION: DM and HIV synergistically increased the odds of TB symptoms according to these retrospective data. Future studies should prospectively evaluate synergism between HIV and DM in increasing the risk of active TB.

PURPOSE: To determine whether retention or removal of teeth in line of mandibular fractures affects the incidence of postoperative complications. To evaluate the fate of teeth retained in mandibular fractures based on location of fracture line in relation to apical foramen and lateral periodontium of retained tooth. METHOD: 51 mandibular fracture sites in 39 patients were treated by open reduction and internal fixation using miniplates. Teeth in line of fracture were removed if showed extensive caries, excessive mobility of tooth, or root fracture. Accordingly patients were divided into two groups, group I tooth removed (15 sites) and group II tooth retained (36 sites). Teeth retained in fracture line were classified based on position of the fracture in relation to apical foramen and the lateral periodontium of involved tooth estimated from preoperative panoramic radiograph into four types. Postoperative periodic follow up done for 1 year and seen for incidence of postoperative complications and fate of tooth in line of fracture. RESULTS: Out of 36 fracture sites in which teeth were retained 5 (13.89%) showed postoperative complications, and out of 15 fracture sites in which teeth were removed 3 (20%) showed postoperative complications. Out of 36 fracture sites in which tooth was retained we found in 3 cases fracture line passed through 2 adjacent teeth. Thus we had in total 39 teeth in fracture line out of them 26 required no treatment 9 required endodontic treatment and 4 teeth required extraction. Need for extraction and endodontic treatment was found more in type I and type III relation. CONCLUSION: There is an increased risk for postoperative complications when a tooth is removed, although it is not statistically significant. Evaluation of fate of retained teeth showed better prognosis of teeth in type II cases than type III and type I cases. Results of this study leads to conclusions that teeth associated with mandibular fractures need not be removed on prophylactic basis.
RESUMEN
BACKGROUND: The oral mucosa lining the oral cavity is composed of epithelium supported by connective tissue. The shape of the epithelial-connective tissue interface has traditionally been used to describe physiological and pathological changes in the oral mucosa. AIM: The aim is to evaluate the morphometric complexity in normal, dysplastic, well-differentiated, and moderately differentiated squamous cell carcinoma (SCC) of the oral mucosa using fractal geometry. MATERIALS AND METHODS: A total of 80 periodic acid-Schiff stained histological images of four groups: normal mucosa, dysplasia, well-differentiated SCC, and moderately differentiated SCC were verified by the gold standard. These images were then subjected to fractal analysis. STATISTICAL ANALYSIS: ANOVA and post hoc test: Bonferroni was applied. RESULTS: Fractal dimension (FD) increases as the complexity increases from normal to dysplasia and then to SCC. Normal buccal mucosa was found to be significantly different from dysplasia and the two grades of SCC (P < 0.05). ANOVA of fractal scores of four morphometrically different groups of buccal mucosa was significantly different with F (3,76) = 23.720 and P< 0.01. However, FD of dysplasia was not significantly different from well-differentiated and moderately differentiated SCC (P = 1.000 and P = 0.382, respectively). CONCLUSION: This study establishes FD as a newer tool in differentiating normal tissue from dysplastic and neoplastic tissue. Fractal geometry is useful in the study of both physiological and pathological changes in the oral mucosa. A new grading system based on FD may emerge as an adjuvant aid in cancer diagnosis.

An ecosystem disruptive bloom of red Noctiluca scintillans (hereafter Noctiluca) was observed in coastal waters of the north-western Bay of Bengal during April 2014. Based on the principle of phytoplankton group/species specific remote sensing reflectance (Rrs), a technique of detecting green Noctiluca and diatom was developed earlier using Rrs at 443, 488, and 531 nm of Moderate Imaging Spectroradiometer-Aqua (MODIS). This was appropriately modified to detect bloom of red Noctiluca in coastal waters of the Bay of Bengal. Additional Rrs data at longer wavelengths viz. 667 and 678 nm were included in the existing algorithm, and the spectral shapes were accounted to detect the bloom of red Noctiluca. The classification scheme discriminates red Noctiluca from the green form of the same species and diatom. Phytoplankton group/species products were generated using the modified approach and validated with the reported events of red and green Noctiluca blooms in the Indian coastal waters. The present study also highlights two specific results based on MODIS retrieved time-series phytoplankton group/species image analysis: first, the observation of coexistence of diatom, red, and green Noctiluca in coastal waters of the north-western Bay of Bengal, and the second, phytoplankton community shift resulting in red/green Noctiluca proliferation following diatom.

BACKGROUND: The prognosis of children with juvenile dermatomyositis (JDM) has improved remarkably since the 1960's with the use of corticosteroid and immunosuppressive therapy. Yet there remain a minority of children who have refractory disease. Since 2003 the sporadic use of biologics (genetically-engineered proteins that usually are derived from human genes) for inflammatory myositis has been reported. In 2011-2016 we investigated our collective experience of biologics in JDM through the Childhood Arthritis and Rheumatology Research Alliance (CARRA). METHODS: The JDM biologic study group developed a survey on the CARRA member experience using biologics for Juvenile DM utilizing Delphi consensus methods in 2011-2012. The survey was completed online by the CARRA members interested in JDM in 2012. A second survey was similarly developed that provided more opportunity to describe their experiences with biologics in JDM in detail and was completed by CARRA members in Feb 2013. During three CARRA meetings in 2013-2015, nominal group techniques were used for achieving consensus on the current choices of biologic drugs. A final survey was performed at the 2016 CARRA meeting. RESULTS: One hundred and five of a potential 231 pediatric rheumatologists (42%) responded to the first survey in 2012. Thirty-five of 90 had never used a biologic for Juvenile DM at that time. Fifty-five of 91 (denominators vary) had used biologics for JDM in their practice with 32%, 5%, and 4% using rituximab, etanercept, and infliximab, respectively, and 17% having used more than one of the three drugs. Ten percent used a biologic as monotherapy, 19% a biologic in combination with methotrexate (mtx), 52% a biologic in combination with mtx and corticosteroids, 42% a combination of a biologic, mtx, corticosteroids (steroids), and an immunosuppressive drug, and 43% a combination of a biologic, IVIG and mtx. The results of the second survey supported these findings in considerably more detail with multiple combinations of drugs used with biologics and supported the use of rituximab, abatacept, anti-TNFα drugs, and tocilizumab in that order. One hundred percent recommended that CARRA continue studying biologics for JDM. The CARRA meeting survey in 2016 again supported the study and use of these four biologic drug groups. CONCLUSIONS: Our CARRA JDM biologic work group developed and performed three surveys demonstrating that pediatric rheumatologists in North America have been using multiple biologics for refractory JDM in numerous scenarios from 2011 to 2016. These survey results and our consensus meetings determined our choice of four biologic therapies (rituximab, abatacept, tocilizumab and anti-TNFα drugs) to consider for refractory JDM treatment when indicated and to evaluate for comparative effectiveness and safety in the future. Significance and Innovations This is the first report that provides a substantial clinical experience of a large group of pediatric rheumatologists with biologics for refractory JDM over five years. This experience with biologic therapies for refractory JDM may aid pediatric rheumatologists in the current treatment of these children and form a basis for further clinical research into the comparative effectiveness and safety of biologics for refractory JDM.

INTRODUCTION: Arch bars are regularly used in the management of dentoalveolar and minimally displaced fractures of the maxilla or mandible and luxation or avulsion of teeth by maxillofacial surgeons. The procedure for arch bar placement has remained unchanged over the period of years, and this coupled with the difficulty in maintenance of oral hygiene is a problem that begs attention. TECHNIQUE: We have devised a technique to overcome these hurdles and achieve adequate intramaxillary splinting. The technique uses an arch wire and ligature wire assembly instead of the conventional arch bar. CONCLUSION: This technique is easy to learn and can thus be used as a rapid yet robust alternative to the conventional arch bar for dentoalveolar and minimally displaced fractures.
RESUMEN
Salivary gland calculi account for the most common disease of the salivary glands. Most of the salivary calculi are small in size. Some calculi that reach several centimeters are reported as megaliths or giant calculi in the literature. They may occur in any of the salivary gland ducts but are most common in Wharton's duct and in the submandibular gland. This report presents clinical and radiographical sign of an unusually large sialolith. A patient came with pain in the floor of mouth. There was a swelling on floor of mouth on the left side. Radiographical examination revealed large irregular radio-opaque mass superimposed on left lateral incisor to molar areas. This case report describes a patient presenting with an unusually large submandibular gland duct sialolith, the subsequent patient management, the etiology, diagnosis, and its treatment.
RESUMEN
BACKGROUND: HIV testing, diagnosis and treatment programs have expanded globally, particularly in resource-limited settings. Diagnosis must be followed by determination of treatment eligibility and referral to care prior to initiation of antiretroviral treatment (ART). However, barriers and delays along these early steps in the treatment cascade may impede successful ART initiation. New strategies are needed to facilitate the treatment cascade. We evaluated the role of on site CD4+ T cell count phlebotomy services by nurses in facilitating pre-ART care in a community-based voluntary counseling and testing program (CBVCT) in rural South Africa. METHODS: We retrospectively evaluated CBVCT services during five continuous time periods over three years: three periods when a nurse was present on site, and two periods when the nurse was absent. When a nurse was present, CD4 count phlebotomy was performed immediately after HIV testing to determine ART eligibility. When a nurse was absent, patients were referred to their local primary care clinic for CD4 testing. For each period, we determined the proportion of HIV-positive community members who completed CD4 testing, received notification of CD4 count results, as well as the time to test completion and result notification. RESULTS: Between 2010 and 2013, 7213 individuals accessed CBVCT services; of these, 620 (8.6 %) individuals were HIV-positive, 205 (33.1 %) were eligible for ART according to South African national CD4 count criteria, and 78 (38.0 % of those eligible) initiated ART. During the periods when a professional nurse was available to provide CD4 phlebotomy services, HIV-positive clients were significantly more likely to complete CD4 testing than during periods when these services were not available (85.5 % vs. 37.3 %, p < 0.001). Additionally, when nurses were present, individuals were significantly more likely to be notified of CD4 results (60.6 % vs. 26.7 %, p <0.001). The time from HIV screening to CD4 test completion was also significantly shorter during nurse presence than nurse absence (median 8 days (IQR 4-19) vs. 35 days (IQR 15-131), p < 0.001). CONCLUSIONS: These findings indicate that in addition to CBVCT, availability of on site CD4 phlebotomy may reduce loss along the pre-ART care cascade and facilitate timely entry into HIV care.

Dexmedetomidine is a selective alpha-2-adrenoceptor agonist used as an adjuvant for regional anaesthesia. We studied its efficacy as an adjuvant to lidocaine in infraorbital nerve block in 90 patients divided equally into three groups. The first group (control) was given 2% lidocaine 2ml only, the second, 2% lidocaine 2ml with dexmedetomidine 14µg peripherally (peripheral group), and the third, 2% lidocaine 2ml peripherally with dexmedetomidine 14µg systemically (systemic group). Onset of anaesthesia, duration of action, blood pressure, oxygen saturation, and heart rate were evaluated. The mean (SD) onset of action was faster in the peripheral group (185 (39.02) seconds) than in the others (control: 261.67 (67.02); systemic: 217.37 (34.86) seconds). The duration of action was longer in the peripheral group (124.87 (19.75) minutes) than in the others (control: 70.43 (13.62); systemic: 88.83 (20.63) minutes). Differences in blood pressure, oxygen saturation, and heart rate measured at different intervals were not significant. The addition of 7mg/L dexmedetomidine to lidocaine perineurally speeds up the onset of action and prolongs the duration of anaesthesia.

OBJECTIVE: Juvenile idiopathic arthritis (JIA) is a heterogeneous group of disorders characterized by chronic arthritis in children with unknown etiology. Although research evaluating environmental or early-life exposures in JIA is scarce, there are data to suggest that infections, smoking exposure, and lack of breastfeeding play a role. This case-control study investigated the association of selected environmental and early-life risk factors with the development of JIA. METHODS: JIA cases were identified at a major pediatric rheumatology outpatient clinic. Each case was asked to identify up to 3 healthy playmates of similar age and same sex to serve as controls. Parents/caregivers of cases and controls completed a questionnaire on selected environmental and early-life exposures. Conditional logistic regression adjusted for age and socioeconomic status was used to determine the odds ratio (OR) for developing JIA with 95% confidence intervals (95% CIs) for the playmate-matched design. RESULTS: Included in the study were 225 JIA cases and 138 controls. Compared to playmate-matched controls, preterm delivery (OR 1.8 [95% CI 1.2-2.7]) was associated with JIA. There was no association between JIA and household smoking or maternal prenatal smoking, breastfeeding, hospitalization with infection in the first year of life, daycare attendance before 6 years of age, household pets, or residential area prior to the onset of JIA. CONCLUSION: There was no association between the previously reported risk factors of smoking, early-life infection, or breastfeeding and development of JIA in this study. The association of preterm delivery with JIA needs to be further studied.

SETTING: Active case finding is a World Health Organization (WHO) endorsed strategy for improving tuberculosis (TB) case detection. Despite WHO recommendations for active case finding among people who inject drugs (PWID), few studies have been published. The historical focus of case finding has been in populations that are human immunodeficiency virus-positive, incarcerated or at higher occupational risk. OBJECTIVE: We sought to examine the yield of active case finding among PWID newly started on methadone in Tanzania. DESIGN: Of 222 methadone clients, 156 (70%) met with study administrators; 150 consented to participate, 139 (93%) of whom were male. The median age was 34 years. A symptom-based questionnaire was developed by the investigators and administered to every consenting patient by a native Swahili speaker. RESULTS: Of the 150 patients surveyed, 16 (11%) had one or more TB symptoms and were referred for laboratory testing. Six new TB cases were identified in this active case finding program, with a prevalence of 4%. CONCLUSION: This study presents the first data on TB prevalence in a population of PWID in Tanzania. This prevalence is 23 times that of the general Tanzanian TB prevalence of 0.2%. These results have significant implications for TB control.

PURPOSE: The aim of the present randomized study was to evaluate the efficacy of intermaxillary fixation screw (IMFS) versus eyelet interdental wiring for intermaxillary fixation (IMF) in minimally displaced mandibular fractures. MATERIALS AND METHODS: A total of 50 patients with a minimally displaced mandibular fracture were enrolled, with 25 patients randomly selected for each group. In group I (study group, n = 25), the patients were treated using IMFS, and in group II (control group, n = 25), they received eyelet interdental wiring. Both techniques were assessed for the following parameters: time required for placement and removal of each type of IMF technique, time required for placement of IMF wires, postoperative occlusion, stability of the IMF wire, local anesthesia requirement during removal of each fixation type, oral hygiene status, glove perforation rate, and complications associated with both techniques. The collected data were analyzed using Student's unpaired t test or χ2 test. P < .05 was considered significant and the Statistical Package for Social Sciences software, version 10, was used for analysis. RESULTS: The average time required for placement in groups I and II was 17.56 and 35.08 minutes, respectively (P = .000). The time required for placement of the IMF wire in group I was 2.1 minutes and in group II was 6 minutes. The oral hygiene status was assessed, and the mean plaque index score for groups I and II was 1.44 and 2.12, respectively (P = .00). The glove perforation rate was much less in group I than in group II. Finally, the most common complication in both groups was mucosal growth. CONCLUSIONS: The results established the supremacy of IMFS compared with eyelet interdental wiring. Thus, we have concluded that IMFS, in the present scenario, is a safe and time-saving technique. IMFS is a cost-effective, straightforward, and viable alternative to cumbersome eyelet interdental and other wiring techniques for providing IMF, with satisfactory occlusion during closed reduction or intraoperative open reduction internal fixation of fractures. In addition, oral hygiene can be maintained, and the glove perforation rate was very low using IMFS. The relatively small sample size and limited follow-up period were the study limitations.

SETTING: Intensive case finding (ICF) for tuberculosis (TB) is recommended by the World Health Organization among known human immunodeficiency virus (HIV) patients. However, ICF may also be appropriate in generalized patient populations. OBJECTIVE: To evaluate the yield of ICF in a general medical clinic in a high HIV prevalence setting. METHODS: A nurse designated as a 'cough officer' identified clinic attendees with cough of >2 weeks and collected sputum for evaluation at the hospital and provincial referral laboratories. We retrospectively evaluated the number and proportion of patients with microbiologically confirmed TB identified in 2007-2008. RESULTS: Among 56 207 clinic attendees, 1442 (2.6%) TB suspects were identified and 122 (8.5%) were sputum Ziehl-Neelsen (ZN) positive. Of 389 available results, 72 (18.5%) were auramine-positive and 99 (25.4%) were culture-positive; multidrug-resistant and extensively drug-resistant TB were identified in 16 (16.2%). The number needed to screen was 11.8 patients to identify one ZN-positive case and 3.9 to identify one culture-positive case. CONCLUSIONS: A nurse-facilitated cough officer program successfully identified TB suspects and drug-susceptible and drug-resistant TB. Culture was more sensitive for TB screening and critical for identifying drug resistance. ICF is operationally feasible, and should be expanded to general medical clinics in high HIV and TB prevalence, resource-limited settings.
RESUMEN
STUDY OBJECTIVE: To evaluate the outcome of airway management in patients with complex maxillofacial fracture by submental intubation, time required for intubation, accidental extubation, and postoperative complications. DESIGN: Retrospective study. SETTING: University-affiliated hospital. MEASUREMENTS: The medical records of the 10 patients who underwent submental intubation from December 2008 to June 2011 were reviewed. MAIN RESULTS: At the end of the procedure, all 10 patients were extubated without any complications. Postoperatively, only one patient presented with superficial infection of the submental wound. CONCLUSIONS: Submental endotracheal intubation is a simple technique with very low morbidity, and may be used as an alternative to tracheostomy in selected cases of maxillofacial trauma.

BACKGROUND: Plants are ubiquitous in nature and are essential for human life, though some do have detrimental effects. In India, there are various indigenous and foreign plants that are well known to cause dermatitis, Parthenium hysterophorus being the foremost. AIMS OF THE STUDY: To study the clinical features of patients presenting with plant dermatitis and evaluate plant allergen series patch test results. MATERIALS AND METHODS: 50 patients with suspected plant dermatitis were evaluated regarding evolution of dermatitis, precipitating factors and contact with various plants. 31 patients (62%) complained of photo sensitivity and 24 (48%) had involvement of sun-exposed areas. Our provisional diagnoses included allergic contact dermatitis in 16, air borne contact dermatitis in 9, phytophotodermatitis in 7, photodermatitis in 6, airborne contact dermatitis to other causes in 4, phytodermatitis in 3. Patients were patch tested with Indian standard series of allergens as well as plant allergen series consisting of common allergenic plants of local flora in and around Manipal and also with plants strongly suspected by the patient. 35 tested positive with maximum positives (26 patients, i.e., 52%) to Parthenium hysterophorus (Compositae). RESULTS: The result of patch testing was correlated with the history and clinical examination and relevance established. CONCLUSIONS: Majority of the patients with clinically suspected plant dermatitis belonged to 3(rd) or 4(th) decade and Parthenium was the leading plant allergen Sensitization to Leguminosae plants and Hopea ponga, seen in 9 cases, have not been reported earlier in literature.
