Lamotrigine-induced Stevens-Johnson syndrome in a 25 year old lady

Stevens-Johnson syndrome (SJS) is an immune-complex mediated hypersensitivity reaction and has been linked as an adverse side effect to many drugs. This case is about a 25 year old woman who had lamotrigine-induced Stevens-Johnson syndrome which is known to occur but is rare. Lamotrigine, an anticonvulsive medication and also a commonly used mood stabilizer was prescribed to the patient to treat symptoms of anxiety and depression. The patient developed Stevens-Johnson syndrome 5 weeks after start of therapy. This case is discussed for its relevance to the use of lamotrigine which is currently prescribed very commonly in psychiatric practices

Demonstration of HDM-4 in Evaluating Different Investment Alternatives for Unpaved Road

In the context of under developing countries like Afghanistan, poverty can be reduced by proper management and effective use of infrastructure budget, and provision of labor-intensive construction projects. The labor-intensive works approach can bolster livelihoods in the immediate term, create new small businesses in road maintenance and works, encourage workers to save and invest wages in other kinds of new micro-enterprises, and improve critical road infrastructure to sustained economic growth. In this study, the use of the HDM-4 model is demonstrated in defining the road improvement and maintenance works and selection of optimum maintenance and rehabilitation strategies available for the road sector under constrained budget available for the road sectors in Afghanistan. This study presents the economic analysis and justification of upgrading an existing engineered gravel road to a paved standard evaluating 8 different investment options. The existing road is 22.02 km long and passes through hilly topography

Standardization of Spacing and Soil Volume Wetting for Drip Irrigationin Papaya (Carica papaya L.)

Field experiments in two crops of papaya were conducted at ICAR-Indian Institute of Horticultural Research for four years during 2016-19 to standardise spacing with optimum soil volume wetting for drip irrigation. Narrowing the plant rows drastically reduced the plant height while leaf production affected significantly due to reduction in intra row spacing. The height at first fruiting was significantly lower with a spacing of 1.8 m x 1.5 m (56.4 cm) significantly differing from both 1.5 m x 1.5 m (60.9 cm) or 1.8 m x 1.8 m (66.8 cm). Significantly higher mean fruit yield (42.2 t/ha) was recorded with the spacing of 1.5 m x 1.5m as compared to either 1.8m x 1.5m (23.4 t/ha) or 1.8m x 1.8m (22.1 t/ha). Significantly higher water use efficiency (71.3 kg/ha.mm) was recorded in papaya by following closer spacing of 1.5 m x 1.5 m. Among the interactions, higher papaya yield (48.0 t/ha) was recorded with normal drip irrigation (80% soil volume wetting) under closer spacing (1.5 m. x 1.5 m). Further, higher water use efficiency (129 kg/ha. mm) could be obtained by scheduling the irrigation at 30% soil volume wetting especially by planting at 1.5 m. x 1.5 m. spacing suggesting its suitability for water scarcity areas

Partial root zone drying irrigation in papaya (Carica papaya L.) for enhanced water use efficiency under limited water situations

Field experiments were conducted during 2015-17 at ICAR-Indian Institute of Horticultural Research, Hessaraghatta, Bengaluru, to standardize the partial root zone drying irrigation in papaya with 12 treatments in RBD design. The results indicated that better soil moisture in the root zone could be maintained under drip irrigation by shifting laterals on either side at fortnightly intervals as compared to fixed laterals with thesame amount of water. Significantly more primary roots (16.5/plant) were observed when irrigation was scheduled on one side with single emitter meeting 60% of the evaporative demand. PRD irrigation through shifting of laterals recorded significantly higher transpiration rate especially at 50% of ER (8.05 m mol m-2 s-1) as compared to the control (3.95m mol m-2 s-1). Further, the same treatment recorded significantly lower fruit cavity index (0.26) with relatively higher fruit volume (1388 cm3). Irrigating papaya only on one side with single emitter resulted in significantly higher T.S.S (13.0%). Higher water productivity (23.7 kg/m3) could be obtained by scheduling the irrigation at 40% evaporation replenishment through shifting of laterals with saving of substantial water (1285m3/ha) resulting in higher water use efficiency (237.4 kg/ha.mm)

ROLE OF JALAUKAVACHARANA (HIRUDOTHERAPY) IN THE MANAGEMENT OF SCALP PSORIASIS - A CASE STUDY

Psoriasis is a common, Chronic, inflammatory, multisystem disease of the Skin. Psoriasis localized to certain areas of the body like scalp, nails, palms and soles need special treatment modalities and it is very difficult to control the disease in these areas because of various reasons like unrealistic expectations of the patients, time consuming treatment approaches, cosmetic- non acceptability, non-compliance by patient. Scalp is the first site of Involvement in up to 25% of patients of Psoriasis. In Modern science, psoriasis is treated with Photo chemotherapy and Corticosteroids which has adverse side effects like hepatic & nephrotoxicity. However in Ayurvedic Texts use of Leech therapy is mentioned beneficial in the many skin disorders and also mentioned that the diseases treated with Raktamokshana has less chances of re-occurrence. This article covers the use of Leech therapy (Jalaukavachanrana) in a case of Scalp psoriasis where the patient undergone Jalaukavacharana therapy for 3 sittings in OPD without any supportive medications internally or any other therapies. The important observation found was there is a significant decrease in the characteristics like Erythema, Thickening, Scaling and True Area percent of the scalp affected by psoriasis. On a whole, Jalaukavacharana was found to be very effective even without any internal medications. If it is supported by internal medications we can expect better results in the management of Scalp Psoriasis.

The Non-Destructive and Nano-Microstructural Characterization of Thermal-Barrier Coatings

The durability of thermal barrier coatings (TBCs) plays an important role in the service reliability and maintainability of hot-section components in advanced turbine engines for aerospace and utility applications. Photostimulated luminescence spectroscopy (PSLS) and electrochemical impedance spectroscopy (EIS) are being concurrently developed as complimentary nondestructive evaluation (NDE) techniques for quality control and liferemain assessment of TBCs. This paper discusses recent achievements in understanding the residual stress, phase constituents, and electrochemical resistance (or capacitance) of TBC constituents—with an emphasis on the thermally grown oxide. Results from NDE by PSLS and EIS are correlated to the nano- and microstructural development of TBCs

Corrosion behavior of ultrafine-grained AA2024 aluminum alloy produced by cryorolling.

The objectives of this study were to produce ultrafine-grained (UFG) AA2024 aluminum alloy by cryorolling followed by aging and to evaluate its corrosion behavior. Solutionized samples were cryorolled to ~85% reduction in thickness. Subsequent aging resulted in a UFG structure with finer precipitates of Al2CuMg in the cryorolled alloy. The (1) solutionized and (2) solutionized and cryorolled samples were uniformly aged at 160°C/24 h and were designated as CGPA and CRPA, respectively; these samples were subsequently subjected to corrosion studies. Potentiodynamic polarization studies in 3.5wt% NaCl solution indicated an increase in corrosion potential and a decrease in corrosion current density for CRPA compared to CGPA. In the case of CRPA, electrochemical impedance spectroscopic studies indicated the presence of two complex passive oxide layers with a higher charge transfer resistance and lower mass loss during intergranular corrosion tests. The improved corrosion resistance of CRPA was mainly attributed to its UFG structure, uniform distribution of fine precipitates, and absence of coarse grain-boundary precipitation and associated precipitate-free zones as compared with the CGPA alloy

Prescription pattern of alpha blockers in the treatment of benign prostatic hyperplasia in India: a paper based survey

Background: Benign prostatic hyperplasia (BPH) is the most common urological condition. The treatment of BPH depends on the severity of symptoms which aims to improve symptoms, lower the risk of progression and improve quality of life. The aim of this survey was to understand the prescription pattern of alpha blockers in the treatment of BPH among clinicians of India.Methods: A cross-sectional questionnaire-based survey was conducted between September to December 2018. Data regarding the management of BPH using α-blockers were filled by clinicians and collated for data analysis using appropriate statistical test.Results: Total of 1764 clinicians’ responses was collected and the result was analysed. According to the survey, 47.68% of clinicians felt that severity of the BPH symptoms is most common deciding factor for medical management of BPH. For the pharmacological management of BPH patients, around 58% of clinicians opted for α blockers monotherapy as a preferred option. Among α blockers, 65.14% of clinicians preferred tamsulosin as first line therapy for management of BPH patients. In this survey, 81.75% of clinicians believed that tamsulosin offers highest persistence rate among commonly prescribed α blockers. Looking at the switching to a second α-blocker, 75.45% of clinicians felt that tamsulosin shows the highest return rate following initiation of a second α-blocker. More than 90% of clinicians felt that favourable efficacy or tolerability of tamsulosin is due to its highest persistence and highest return rates.Conclusions: Tamsulosin is the most commonly preferred and prescribed α-blocker by Indian clinicians due to its favourable efficacy or tolerability
