ABSTRACT
BACKGROUND: Hormone receptor (HR)-positive, HER2/neu-negative breast cancers have a sustained risk of recurrence up to 20 years from diagnosis. TEAM (Tamoxifen, Exemestane Adjuvant Multinational) is a large, multi-country, phase III trial that randomized 9776 women for the use of hormonal therapy. Of these 2754 were Dutch patients. The current study aims for the first time to correlate the ten-year clinical outcomes with predictions by CanAssist Breast (CAB)-a prognostic test developed in South East Asia, on a Dutch sub-cohort that participated in the TEAM. The total Dutch TEAM cohort and the current Dutch sub-cohort were almost similar with respect to patient age and tumor anatomical features. METHODS: Of the 2754 patients from the Netherlands, which are part of the original TEAM trial, 592 patients' samples were available with Leiden University Medical Center (LUMC). The risk stratification of CAB was correlated with outcomes of patients using logistic regression approaches entailing Kaplan-Meier survival curves, univariate and multivariate cox-regression hazards model. We used hazard ratios (HRs), the cumulative incidence of distant metastasis/death due to breast cancer (DM), and distant recurrence-free interval (DRFi) for assessment. RESULTS: Out of 433 patients finally included, the majority, 68.4% had lymph node-positive disease, while only a minority received chemotherapy (20.8%) in addition to endocrine therapy. CAB stratified 67.5% of the total cohort as low-risk [DM = 11.5% (95% CI, 7.6-15.2)] and 32.5% as high-risk [DM = 30.2% (95% CI, 21.9-37.6)] with an HR of 2.90 (95% CI, 1.75-4.80; P < 0.001) at ten years. CAB risk score was an independent prognostic factor in the consideration of clinical parameters in multivariate analysis. At ten years, CAB high-risk had the worst DRFi of 69.8%, CAB low-risk in the exemestane monotherapy arm had the best DRFi of 92.7% [vs CAB high-risk, HR, 0.21 (95% CI, 0.11-0.43), P < 0.001], and CAB low-risk in the sequential arm had a DRFi of 84.2% [vs CAB high-risk, HR, 0.48 (95% CI, 0.28-0.82), P = 0.009]. CONCLUSIONS: Cost-effective CAB is a statistically robust prognostic and predictive tool for ten-year DM for postmenopausal women with HR+/HER2-, early breast cancer. CAB low-risk patients who received exemestane monotherapy had an excellent ten-year DRFi.

Crop yield varies considerably within agroecology depending on the genetic potential of crop cultivars and various edaphic and climatic variables. Understanding site-specific changes in crop yield and genotype × environment interaction are crucial and needs exceptional consideration in strategic breeding programs. Further, genotypic response to diverse agro-ecologies offers identification of strategic locations for evaluating traits of interest to strengthen and accelerate the national variety release program. In this study, multi-location field trial data have been used to investigate the impact of environmental conditions on crop phenological dynamics and their influence on the yield of mungbean in different agroecological regions of the Indian subcontinent. The present attempt is also intended to identify the strategic location(s) favoring higher yield and distinctiveness within mungbean genotypes. In the field trial, a total of 34 different mungbean genotypes were grown in 39 locations covering the north hill zone (n = 4), northeastern plain zone (n = 6), northwestern plain zone (n = 7), central zone (n = 11) and south zone (n = 11). The results revealed that the effect of the environment was prominent on both the phenological dynamics and productivity of the mungbean. Noticeable variations (expressed as coefficient of variation) were observed for the parameters of days to 50% flowering (13%), days to maturity (12%), reproductive period (21%), grain yield (33%), and 1000-grain weight (14%) across the environments. The genotype, environment, and genotype × environment accounted for 3.0, 54.2, and 29.7% of the total variation in mungbean yield, respectively (p < 0.001), suggesting an oversized significance of site-specific responses of the genotypes. Results demonstrated that a lower ambient temperature extended both flowering time and the crop period. Linear mixed model results revealed that the changes in phenological events (days to 50 % flowering, days to maturity, and reproductive period) with response to contrasting environments had no direct influence on crop yields (p > 0.05) for all the genotypes except PM 14-11. Results revealed that the south zone environment initiated early flowering and an extended reproductive period, thus sustaining yield with good seed size. While in low rainfall areas viz., Sriganganagar, New Delhi, Durgapura, and Sagar, the yield was comparatively low irrespective of genotypes. Correlation results and PCA indicated that rainfall during the crop season and relative humidity significantly and positively influenced grain yield. Hence, the present study suggests that the yield potential of mungbean is independent of crop phenological dynamics; rather, climatic variables like rainfall and relative humidity have considerable influence on yield. Further, HA-GGE biplot analysis identified Sagar, New Delhi, Sriganganagar, Durgapura, Warangal, Srinagar, Kanpur, and Mohanpur as the ideal testing environments, which demonstrated high efficiency in the selection of new genotypes with wider adaptability.
ABSTRACT
Under global climate change, high-temperature stress is becoming a major threat to crop yields, adversely affecting plant growth, and ultimately resulting in significant yield losses in various crops, including chickpea. Thus, identifying crop genotypes with increased heat stress (HS) tolerance is becoming a priority for chickpea research. Here, we assessed the response of seven physiological traits and four yield and yield-related traits in 39 chickpea genotypes grown in normal-sown and late-sown environments [to expose plants to HS (>32/20°C) at the reproductive stage] for two consecutive years (2017-2018 and 2018-2019). Significant genetic variability for the tested traits occurred under normal and HS conditions in both years. Based on the tested physiological parameters and yield-related traits, GNG2171, GNG1969, GNG1488, PantG186, CSJ515, RSG888, RSG945, RVG202, and GNG469 were identified as promising genotypes under HS. Further, ten heat-tolerant and ten heat-sensitive lines from the set of 39 genotypes were validated for their heat tolerance (32/20°C from flowering to maturity) in a controlled environment of a growth chamber. Of the ten heat-tolerant genotypes, GNG1969, GNG1488, PantG186, RSG888, CSJ315, and GNG1499 exhibited high heat tolerance evidenced by small reductions in pollen viability, pollen germination, and pod set %, high seed yield plant-1 and less damage to membranes, photosynthetic ability, leaf water status, and oxidative processes. In growth chamber, chlorophyll, photosynthetic efficiency, pollen germination, and pollen viability correlated strongly with yield traits. Thus, GNG1969, GNG1488, PantG186, RSG888, CSJ315, and GNG1499 genotypes could be used as candidate donors for transferring heat tolerance traits to high-yielding heat-sensitive varieties to develop heat-resilient chickpea cultivars.
ABSTRACT
INTRODUCTION: Yellow oleander (Thevetia peruviana), which belongs to the Apocyanaceae family, is a common shrub seen throughout the tropics. All parts of the plant contain high concentrations of cardiac glycosides which are toxic to cardiac muscle and the autonomic nervous system. Here, we describe the clinical profile of patients with oleander poisoning and their outcomes. METHODS AND MATERIALS: This retrospective study was conducted over a period of 12 months (March 2016 to February 2017). The data was extracted from the inpatient electronic medical records. Adult patients with a diagnosis of acute yellow oleander poisoning were included in the study. Descriptive statistics were obtained for all variables in the study and appropriate statistical tests were employed to ascertain their significance. RESULTS: The study comprised 30 patients aged 30.77 ± 12.31 (mean ± SD) who presented at 12.29 ± 8.48 hours after consumption of yellow oleander. Vomiting (80%) was the most common presenting symptom. Metabolic abnormalities at presentation included hyperchloremia in 22 patients and metabolic acidosis (bicarbonate <24 mmol/L) in 29 patients. Fifteen (50%) patients had abnormal ECG, of which second-degree AV block was the commonest ECG abnormality seen in 4 (13.3%). Fifteen (50%) patients had transvenous temporary pacemaker insertion (TPI). Having a TPI significantly prolonged the duration of hospital stay (OR 1.85, 95% CI 1.06-3.21, P 0.03). The mortality in the cohort was 2 (6.7%). CONCLUSION: In patients with yellow oleander poisoning, dyselectrolytemia with ECG abnormalities was common. TPI prolonged the duration of hospital stay. Further studies are required to know the indication for and to ascertain the effect of temporary pacing on survival.
ABSTRACT
CONTEXT: In laparoscopic cholecystectomy, pneumoperitoneum results in tachycardia, hypertension, and increased myocardial oxygen demand. These changes are more pronounced in hypertensive patients. The intravenous administration of dexmedetomidine attenuates sympathoadrenal response and provides better hemodynamic stability intraoperatively. AIMS: To evaluate the hemodynamic stabilizing and sedation properties of two different doses of dexmedetomidine including 0.7 µg.kg-1.h-1 and 0.5 µg.kg-1.h-1 in hypertensive patients undergoing laparoscopic cholecystectomy. SETTINGS AND DESIGN: This was a randomized, prospective, double-blind controlled trial. SUBJECTS AND METHODS: A total of 60 controlled hypertensive patients of either sex, aged 30-60 years, and ASA class 2 without any other serious comorbid conditions who were undergoing laparoscopic cholecystectomy under general anesthesia were randomly assigned into three groups of 20 each. Group A and B received loading dose of dexmedetomidine 1 µg.kg-1 over 10 min and maintenance dose at 0.7 and 0.5 µg.kg-1.h-1, respectively. Group C received normal saline infusion only. Hemodynamic parameters (heart rate and systolic, diastolic, and mean arterial pressure) and sedation score were compared at different time intervals among groups. STATISTICAL ANALYSIS USED: The Chi-square test, ANOVA, and Tukey Post hoc Test. RESULTS: Fluctuations in the hemodynamics of hypertensive patients are effectively attenuated by dexmedetomidine and there is no difference in the attenuation of these hemodynamic changes by maintenance dose of 0.5 or 0.7 µg.kg-1.h-1. However, maintenance dose of 0.5 µg.kg-1.h-1 causes lesser sedation. CONCLUSIONS: Dexmedetomidine administered as infusion in a maintenance dose of 0.5 µg.kg-1.h-1 serves as an ideal anesthetic adjuvant in hypertensive patients undergoing laparoscopic cholecystectomy.
ABSTRACT
OBJECTIVE: To determine the efficacy and safety ultrasound-guided percutaneous catheter drainage (US-PCD) in management of various types of ruptured amebic liver abscess including free rupture (FR) with diffuse intraperitoneal fluid collections (DIFC). METHODS: This study analyzed 117 patients with ruptured ALA who underwent US-PCD. The indication for US-PCD was failure to respond to conservative treatment and/or percutaneous needle aspiration. RESULTS: Majority of patients were locally fermented alcohol abusers (95%), and malnourished (75%). Ninety-eight patients had intraperitoneal rupture including 66 contained rupture (CR) with localized intraperitoneal fluid collection (LIFC) and 32 FR with DIFC. Pleuropulmonary complication was found in 19 patients including 13 pleural and 6 pulmonary. A total of 333 catheters were used to drain 202 abscess cavities and associated fluid collections. US-PCD was technically and clinically successful in all cases. Multiple sessions (median 2; range 2-5) of PCD required with upsizing the catheter (median 14 F; range 14-20 F) and placement of additional catheter in 26 (22%) patients. The patients with FR with DIFC required more number of catheters (p = 0.01) and had longer hospital stay (p = 0.01). No major procedure related complication was observed. Six patients developed secondary bacterial infection; two of them presented with cavito-cutaneous fistula at catheter insertion site, and one with cholangitis due to biliary stricture formation necessitating subsequent endoscopic treatment. Post-procedural death occurred from sepsis in a patient with FR. CONCLUSION: US-PCD is a safe and effective mode of treatment for ruptured ALA including FR with DIFCs. We recommend PCD as a first-line therapy for ruptured ALA.

Somatoform pain disorders (SPD) are common, disabling and do not respond well to existing treatment modalities. We investigated the usefulness of 18 sessions of high frequency repetitive transcranial magnetic stimulation delivered at the left dorsolateral prefrontal cortex (DLPFC) in five right-handed patients with SPD. All patients reported significant improvement in pain relief and activities of daily living. High-frequency repetitive transcranial magnetic stimulation (rTMS) delivered at the left DLPFC may be useful in SPD.
ABSTRACT
Nonlinear acoustic wave propagation is considered in an infinite orthotropic thin circular cylindrical waveguide. The modes are non-planar having small but finite amplitude. The fluid is assumed to be ideal and inviscid with no mean flow. The cylindrical waveguide is modeled using the Donnell's nonlinear theory for thin cylindrical shells. The approximate solutions for the acoustic velocity potential are found using the method of multiple scales (MMS) in space and time. The calculations are presented up to the third order of the small parameter. It is found that at some frequencies the amplitude modulation is governed by the Nonlinear Schrödinger Equation (NLSE). The first objective is to study the nonlinear term in the NLSE, as the sign of the nonlinear term determines the stability of the amplitude modulation. On the other hand, at other specific frequencies, interactions occur between the primary wave and its higher harmonics. Here, the objective is to identify the frequencies of the higher harmonic interactions. Lastly, the linear terms in the NLSE obtained using the MMS calculations are validated. All three objectives are met using an asymptotic analysis of the dispersion equation.
ABSTRACT
Multiple intra-oral sinus tracts of dental origin are an uncommon condition. Patients with this condition may undergo surgical extraction, biopsies and antibiotic regimens, but all of them fail with the recurrence of the sinus tract. A proper diagnosis and management are important, to avoid any complications. This case report has described the conventional root canal treatment of a patient who had three distant intra-oral sinuses which had occurred due to an intact tooth with pulp necrosis, who had a history of accidentally biting on a hard food object and having a periapical radiolucency which indicated a chronic periradicular abscess. At follow up examination, the tooth was found to be asymptomatic and radiographically, it showed repair of the lesion.
ABSTRACT
Treatment of fused teeth needs special care and attention to the bizarre anatomy. This paper describes root canal treatment of a fused carious tooth presenting with apical periodontitis. It is a rare case of fusion of the mandibular second molar with a paramolar. There is no literature regarding placement of crown over endodontically treated fused teeth. In this case, the fused teeth were endodontically treated and restored by a porcelain fused to metal crown.

Wandering spleen is a rare occurrence. Torsion of the splenic pedicle is the major life-threatening complication of this entity. Preoperative diagnosis is based on radiological investigation. We report two consecutive cases, one adult and one child, in whom torsion in a wandering spleen was diagnosed based on a typical whirled appearance of the splenic vessels on computed tomography. We present a review of computed tomographic appearance of splenic torsion, and emphasize the "whirled appearance" as a specific sign for splenic torsion in wandering spleen.

Kawasaki disease is a common paediatric vasculitide. It is usually diagnosed by its classical constellation of mucocutaneous signs. Recurrent Kawasaki disease is a rare phenomenon that occurs in approximately 3% of all patients diagnosed with Kawasaki disease. Its presentation is usually similar to the first episode of Kawasaki disease, and early diagnosis with prompt treatment is key in preventing associated cardiovascular morbidities. Recurrent Kawasaki disease is not well reported, and atypical presentations have not been previously reported in medical literature. Here, we report the case of a young girl with recurrent Kawasaki disease who presented atypically with acute airway obstruction secondary to retropharyngeal phlegmon.

In addition to regular professional oral hygiene visits and the application of appropriate preventive medications, successful preventive strategies involve oral health promotion, patient education and patient compliance. The Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) complex has been shown to remineralise tooth surfaces in situ when delivered in oral care products. This complex has a unique ability to deliver bio-available calcium and phosphate when they are needed most. The effectiveness of casein derivatives, specifically CCP-ACP, in caries prevention and lesion reversal has been supported by many controlled clinical studies. This review summarises the research on Casein phosphopeptide-amorphous calcium phosphate complex and provides information related to its benefit in dentistry. Further research is required to provide a scientifically supported recommendation for other clinical applications.

Aneurysm of the cystic artery is not common, and it is a rare cause of hemobilia. Most of reported cases are pseudoaneurysms resulting from either an inflammatory process in the abdomen or abdominal trauma. We report a healthy individual who developed hemobilia associated with cystic artery aneurysm. The patient was managed with cholecystectomy and concomitant aneurysm repair. Visceral artery aneurysms are rare and can rupture with potentially grave outcome due to excessive bleeding. Angiographic embolization is a common method of treatment for visceral artery aneurysms. Open cholecystectomy and aneurysm repair was performed in our patient due to radiological evidence of associated cholecystitis.
ABSTRACT
AIM: This study is an overview of non-polio enterovirus (NPEV) circulating in North India studied from the perspective of poliomyelitis eradication. Wild polio cases declined because of intensive oral polio vaccine immunization. As we approach global eradication of poliovirus (PV), NPEV causing acute flaccid paralysis (AFP) are equal cause of concern. METHODS: A total of 46 653 AFP samples (World Health Organization) and apparently 1000 healthy contacts living in the same geographical area were studied (2004-2007). Serological identification of NPEV was done using RIVM-specific pools (The Netherlands). Untyped (UT)-NPEVs were sequenced directly from reverse transcription-polymerase chain reaction using pan-enterovirus (Pan-EV) primer (CDC, Atlanta, GA) targeting highly conserved 5'un-translated regions of the enterovirus. RESULTS: In this study, 12 513 NPEVs were isolated from the collected stool samples. Seroneutralization had identified 67% of NPEV isolates, whereas 32.6% remained as UT- NPEV. Of the typed NPEVs, Coxsackie-B accounted for 32.3%; followed by echoviruses-11, 12, 13, 7 between 8 and 28%. In sequencing few UT-NPEVs, some were identified also as echovirus-30, 11 and 18 which were probably present in mixtures as they remained UT-NPEV in ENT. Newly classified human enterovirus virus-86 (HEV) (EU079026), HEV-97(EU071767) and HEV-B isolate (EU071768) were isolated in AFP samples. CONCLUSIONS: This study provided definitive information about circulation, prevalence and new emerging NPEV in the polio-endemic region of India, hence they should be considered in AFP surveillance. This would help in adopting and planning new strategies in post-PV eradication era in the country. This is the right time to prepare for the future tasks while we head towards a polio-free region.

CONTEXT: Bar overdentures are popular choices among clinicians worldwide but configurations that provide an optimal biomechanical distribution of stress are still debatable. AIMS: To compare the stresses and elastic flexion between implant supported bar overdentures in various configurations using finite element analysis. SETTINGS AND DESIGN: A CAT scan of a human mandible was used to generate an anatomically accurate mechanical model. MATERIALS AND METHODS: Three models with bars and clips in three different configurations were constructed. Model 1 had a single bar connecting two implants, Model 2 had three bars connecting all the four implants, and Model 3 had two bars connecting the medial and distal implants on the sides only. The models were loaded under static conditions with 100N load distributed at the approximate position of the clip. The mandibular boundary conditions were modeled considering the real geometry of its muscle supporting system. Maximum von Mises stress at the level of the bar and at the bone implant interface were compared in all three models. The flexion of mandible and the bar was also compared qualitatively. STATISTICAL ANALYSIS USED: The analyses were accomplished using the ANSYS software program and were processed by a personal computer. Stress on these models was analyzed after loading conditions. RESULTS: Qualitative comparisons showed that stress at the level of the bar and at the bone implant interface were in the following order: Model 1> Model 3> Model 2. The flexion of the mandible and the bar were in the following order: Model 2 > Model 1 > Model 3. CONCLUSIONS: Four implant bar systems connected by bars on the sides only is a better choice than two implant bar systems and four implant bar systems with bars connecting all four implants.

PURPOSE: Prostate biopsy is often recommended based on increases in prostate specific antigen and/or abnormal digital rectal examination. We investigated the stability of a single positive test during the next 3 consecutive years. MATERIALS AND METHODS: A total of 2,578 participants in a San Antonio screening cohort with 2 or more consecutive annual prostate specific antigen and digital rectal examination tests were identified. Occurrences of an increased prostate specific antigen (2.5 ng/ml or greater) followed by 1 or more nonincreased prostate specific antigen results were compared with similar fluctuations of digital rectal examination from abnormal to normal. RESULTS: In 2,272 men who did not have a biopsy during the study, in 23.3% of 744 incidences of an increased prostate specific antigen with 1 year of followup, the next prostate specific antigen was not increased. In 19.5% of 462 incidences of an increased prostate specific antigen with 2 years of followup, the next 2 consecutive prostate specific antigen levels were not increased. Finally, in 17.5% of 285 incidences of an increased prostate specific antigen with 3 years of followup, the next 3 consecutive prostate specific antigens were not increased. Rates were similar but lower in 221 men with 1 or more negative biopsies during the study and in 85 men in whom prostate cancer eventually developed during the study. In contrast, approximately 70% of abnormal digital rectal examinations were normal the following year even in patients with prostate cancer, and in the majority of incidences remained normal the next 2 to 3 consecutive years. CONCLUSIONS: Occurrences of reversed prostate specific antigen cut point or abnormal digital rectal examination based decisions to biopsy 1 or more years after the initial test are not uncommon, suggesting repetition of these tests.

Segmental resection of the mandible commonly results in deviation of the mandible to the defective side. The amount of deviation depends on the amount of hard and soft tissue involvement, the method of surgical site closure, the degree of impaired tongue function, the number of remaining teeth and the extent of loss of sensory and motor innervations. Prosthodontic treatment along with physical therapy may be useful in reducing mandibular deviation and improving masticatory efficiency. This clinical report describes the use of two rows of nonanatomic teeth on the unresected side. This provided a broader occlusal table and improved masticatory efficiency in our edentulous madibulectomy patient.

Multiple idiopathic external root resorptions of permanent teeth are an infrequent phenomenon. A case report of a patient with multiple idiopathic external apical root resorptions is presented. This case is unusual in that extensive resorption is found bilaterally in supraerupted maxillary molar teeth. The pattern of severe resorption affecting only maxillary supraerupted teeth appears to be unique. No significant systemic, dental, or familial findings could be identified as a possible cause.
