Sensformer: Powering the future with digitalized transformers

Transformer digitalization is a critical aspect of the development of a smart grid. Siemens Energy has developed a digital transformer solution called Sensformer, which integrates various sensors, communication interfaces, and data analytics capabilities into the transformer to enable advanced monitoring, diagnostics, and prediction capabilities. This article presents an overview of the Sensformer and its key features. It describes the installation and commissioning process of the Sensformer and the benefits of the technology in terms of improved reliability, efficiency, and safety of power systems. A case study is presented to demonstrate the features of the Sensformer in real-world applications, such as detecting hot spots in transformer windings, predicting transformer ageing, performing DGA and optimizing transformer loading based on real-time condition monitoring. The results show that the Sensformer can significantly enhance the performance and value of transformers and provide a reliable and cost-effective solution for grid digitalization

Ascorbic acid as an effective alternative for treatment of dapsone poisoning in a child: A case report

Dapsone (DDS – Diamino diphenyl sulfone), a sulfonamide derivative acts by inhibiting PABA incorporation into folic acid. It is commonly used in treating skin diseases. Accidental poisoning in children is uncommon. It results in methaemoglobinemia by causing oxidative stress. Principle of treatment relies on treating methemoglobinemia by using reducing agents like methylene blue or ascorbic acid. Due to the long half-life, dapsone provides a continuing oxidative stress that can cause a recurrence of clinically significant methaemoglobinaemia and hence takes long to treat. Ascorbic acid is effective in treating methemoglobinemia associated with dapsone poisoning as demonstrated in this case report of a four and half year old child’s accidental ingestion of dapsone tablets and presenting with cyanosis. The child was managed successfully with ascorbic acid and supportive treatment

In vitro study of some plant extracts against Alternaria brassicae and Alternaria brassicicola

Madhya Pradesh is an important rapeseed-mustard producing state of India contributing nearly of the total production in the country. The present study aims to evaluate the effectiveness of some botanicals viz., Neem, Eucalyptus, Datura, Pudina, Tulsi, Lantana under crude and Forms @ against 10% Alternaria brassicae under in vitro condition by poisoned food technique. Neem and Eucalyptus were also evaluated in the oil forms.  Nearly all the tested botanicals found effective against these fungi. Among the crude extract 10 per cent the minimum growth was recorded in Neem followed by Eucalyptus, Tulsi, Lantana, Datura and Pudina. Neem was significantly superior over Tulsi, Lantana, Datura and Pudina but at par with Eucalyptus. Under boil forms the minimum radial growth was also recorded in Neem. The oil extract (Neem and Eucalyptus) were found less effective as compared to crude and boil extracts

Efficacy of ruxolitinib cream in vitiligo by patient characteristics and affected body areas: Descriptive subgroup analyses from a phase 2, randomized, double-blind trial

To the Editor: Vitiligo is a chronic autoimmune disease resulting in patches of depigmented skin and reduced quality of life. In a randomized, dose-ranging phase 2 study (NCT03099304) in 157 adult patients, the Janus kinase (JAK) 1/JAK2 inhibitor ruxolitinib cream produced substantial repigmentation of facial and total body vitiligo lesions after 24 weeks, with continued improvement through week 52, and was well tolerated.3 Here, we present treatment response subanalyses from the phase 2 trial

Assessment of Bronchiectasis Severity: The FACED Score versus The Bronchiectasis Severity Index (BSI)

Background: Bronchiectasis is a multi-dimensional, chronic inflammatory and heterogeneous lung disorder characterized by unpredictable clinical course and progression. Two multivariable score systems, the FACED score and the BSI, which are composites of multiple variables have been used to assess the severity and prognosis of bronchiectasis. Objectives: (1) To assess the severity of bronchiectasis in patients using two different validated scores, the FACED score and the Bronchiectasis Severity Index (BSI). (2) To identify microbial profile among bronchiectasis patients and its impact on predicting future exacerbation and hospitalization. Methods: A total of 37 patients from June 2019 to November 2019 were enrolled in this prospective study. The FACED score and BSI score of patients were calculated. Severity of bronchiectasis has been defined by both scores and its impact on exacerbation was examined. Results: Mean age of patients was 45.8 ± 12.7 years. We found mild, moderate and severe bronchiectasis in 17 (45.95%), 15 (40.54%) and 5 (13.51%) patients as assessed by FACED scores. Low, intermediate and high BSI scores were found in 7 (18.92%), 9 (24.32%) and 21 (56.76 %) patients respectively. Patients with high BSI score demonstrated more exacerbations during the follow up period as compared to those with high FACED score. Conclusions: The BSI score is superior to predicting the severity of bronchiectasis as compared to the FACED score. It also helps to identify patients at risk of future exacerbations and hospitalization. Further large-scale studies are recommended to substantiate the findings

Technique and diagnostic utility of saline infusion sonohysterography

The introduction of saline infusion sonohysterography has significantly improved sonographic diagnosis of various endometrial pathologies. This procedure entails instillation of warm saline into the uterine cavity transcervically to provide enhanced visualization of the endometrium during transvaginal ultrasound examination. This article reviews the sonohysterography technique and current utility, as well as the spectrum of imaging features of various endometrial pathologies.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135202/1/ijgo5.pd

Reliability and Convergent Validity of Two Outcome Instruments for Pemphigus

A major obstacle in performing multicenter controlled trials for pemphigus is the lack of a validated disease activity scoring system. Here we assess the reliability and convergent validity of the PDAI (pemphigus disease area index). A group of 10 dermatologists scored 15 patients with pemphigus to estimate the inter- and intra-rater reliability of the PDAI and the recently described ABSIS (autoimmune bullous skin disorder intensity score) instrument. To assess convergent validity, these tools were also correlated with the Physician’s Global Assessment (PGA). Reliability studies demonstrated an intra-class correlation coefficient (ICC) for inter-rater reliability of 0.76 [95% CI = 0.61–0.91] for the PDAI and 0.77 [0.63–0.91] for the ABSIS. The tools differed most in reliability of assessing skin activity, with an ICC of 0.39 [0.17–0.60] for the ABSIS and 0.86 [0.76–0.95] for the PDAI. Intra-rater test-retest reliability demonstrated an ICC of 0.98 [0.96–1.0] for the PDAI and 0.80 [0.65–0.96] for the ABSIS. The PDAI also correlated more closely with the PGA. We conclude that the PDAI is more reproducible and correlates better with physician impression of extent. Subset analysis suggests that for this population of mild to moderate disease activity, the PDAI captures more variability in cutaneous disease than the ABSIS
