Stress and Strain Created Around Miniscrews during En Masse Retraction - A Finite Element Method.

Background: En masse retraction of the anterior teeth may create anchorage problems. The effective means of obtaining anchorage in en masse retraction is by the usage of temporary anchorage devices.

Aims And Objectives: The purpose of this study is focused on stress and strain created around miniscrew during en masse retraction using the cone beam computed tomography (CBCT) data obtained at two intervals and by the finite element analysis done using the CBCT data obtained.

Rasburicase induced methemoglobinemia: A systematic review of descriptive studies.

Purpose: There is an increased number of reports being published on rasburicase-induced methemoglobinemia recently. We aimed to identify and critically evaluate all the descriptive studies that described the rasburicase-induced methemoglobinemia, its treatment approach, and their outcomes.

Methodology: PubMed, Scopus and grey literature databases were searched from inception to January 2022 using search terms "rasburicase" and "methemoglobinemia" without any language and date restriction.

Methotrexate related cutaneous adverse drug reactions: a systematic literature review.

Objectives: Recently, there is an increased number of reports being published on Methotrexate (MTX) related cutaneous manifestations. We aimed to identify and critically appraise descriptive studies describing the MTX related skin manifestations, treatment approach, and their outcomes.

Methodology: An extensive literature search was performed in the PubMed, Embase, and Scopus databases from inception to April 2021 without any restrictions along with the bibliographic search of included studies, grey literature search, and a snowball search was performed in Google and Google Scholar to identify the relevant literature.

Estimation of plasma and RBC acetylcholinesterase in children: An evaluation tool for Hirschsprung's disease?

Background: Increased acetylcholinesterase (AChE) activity on frozen sections of rectal mucosal biopsies accurately diagnoses Hirschsprung disease (HD). But the quest for a biomarker in blood as a screening test prompts one to look for AChE in blood and study its role in HD diagnosis.

Aim: To develop a low-cost reliable method to estimate the AChE activity in plasma and red blood cells (RBCs) in normal children (control) and study its role in HD (test).

A male patient with right-sided thoracic kidney, diabetes mellitus, hearing loss and renal dysfunction.

A 48-year-old man with diabetes mellitus and hypertension was found to have a thoracic right-sided ectopic kidney with a sensorineuronal hearing loss and tubular abnormalities such as hyponatremia, hypokalemia, metabolic alkalosis with microalbuminuria. He was treated with ACEI and sodium and potassium supplements. However, this only partially corrected his metabolic abnormalities.
