AI Article Synopsis
- A standardized method for reformatting CT brain images was established using an anatomical reference line to improve imaging consistency.
- After educational interventions for CT technologists, 200 CT brain examinations were compared (100 preintervention and 100 postintervention) to assess improvements.
- While there was a slight reduction in angle differences and fewer studies without reformatted images, the overall changes were not statistically significant, possibly due to the high workload at the busy care center.
Article Abstract
Purpose: To establish a standardized method of reformatting axial images for computed tomography (CT) brain examinations.
Methods: An anatomic line between the superior orbital rim and the base of the occipital bone (SOR-BS line) was chosen as the standardized reference line. In June 2022, CT technologists at a tertiary care center received an educational presentation and a 1-page reference handout on making standardized CT reformats. This was the quality-of-care intervention. Subsequently, 100 CT brain examinations performed on July 1 to 10, 2020 (preintervention) were analyzed and compared with 100 CT brain examinations performed on July 1 to 10, 2022 (postintervention).
Results: There were no significant differences in the mean angle differences measured between the preintervention (6.2 ± 5.8°) and the postintervention (5.8 ± 4.7°) groups ( = .67). However, the number of CT brain studies with an angle difference of more than 20° decreased from 4 studies to 1 study. In addition, the number of CT brain studies without reformatted images decreased from 5 to 2 studies.
Discussion: The cause for the less-than-optimal adoption of the expected change in CT workflow might be complex and multifactorial. However, the institution in this study is a busy tertiary care center with a chronic shortage of CT technologists. The busy workflow might have contributed to lack of significance for the parameters assessed.
Conclusion: There was a slight but not significant improvement between preintervention and postintervention data.

Background: Exposure to hairs of caterpillars and moths are collectively termed as lepidopterism. Clinical manifestations include cutaneous presentation of localized stinging reaction with wheals or vesiculation, acute urticarial papules and plaques, ophthalmic, oropharyngeal involvement to severe life-threatening anaphylactic reactions with angioedema.
Aims: In this study we have determined the prevalence of various cutaneous, oropharyngeal and ophthalmic manifestations of lepidopterism at a tertiary health care center.

Human bocaviruses (HBoVs) can cause respiratory illness in young children. Although the first HBoV infection in India was reported in 2010, very little information is available about its prevalence, clinical features, or geographic distribution in this country. This study was conducted using 136 respiratory samples from paediatric patients in a tertiary care hospital in Kerala, 21 of which tested positive for HBoV1 and were further characterized through VP1/VP2 gene sequencing.

The emergence of carbapenem-resistant (CRKP) poses a significant public health threat, particularly in low- and middle-income countries (LMICs) with limited surveillance and treatment options. This study examines the genetic diversity, resistance patterns, and transmission dynamics of 66 CRKP isolates recovered over 5 years (2015-2019) after the first case of CRKP was identified at a tertiary care hospital in Lima, Peru. Our findings reveal a shift from to as the dominant carbapenemase gene after 2017.

Objective: Solid organ transplant (SOT) recipients carry a higher incidence of cutaneous squamous cell carcinoma (cSCC) with more aggressive features and worse outcomes compared to immunocompetent (IC) patients. The National Comprehensive Cancer Network advocates peripheral and deep en-face margin assessment such as Mohs micrographic surgery (MMS) for very-high-risk cSCC. We aim to assess the efficacy of MMS in the treatment of SOT immunosuppressed head and neck (HN) cSCC patients.
