This article contains modern data on the etiology, clinical presentation and treatment as well as the differential diagnosis of a rare dermatosis, Sneddon-Wilkinson disease.Clinical observation of subcorneal pustular dermatosis in a 68-year-old woman is reported. Histopathological examination played a key role in making the correct diagnosis. Treatment consisted of a physiotherapeutic approach (311 nm UVB phototherapy) in combination with systemic glucocorticosteroids (dexamethasone). This therapeutic approach (instead of dapsone therapy) can be used due to its relatively good safety profile.

Between coronary artery anomalies, myocardial bridging means an epicardial coronary artery, mostly left anterior descending artery (LAD), running through an intramyocardial “tunnel” (usually in the middle segment), leading during systolic contraction, flow reduction, through the vessel. When this anomaly is associated with a coronary fistula, which “steals” more from the bloodstream, the symptoms are more pronounced, and the management complex is surgical in particular. Despite the presence from birth remains asymptomatic and it becomes clinically manifest later in the third to fourth decade of life, with a diverse palette of symptoms; angina, arrhythmias, and acute myocardial infarction up to sudden death. Diagnosis and particular management, medical, interventional, and surgical should avoid major cardiac complications and sudden death. We present two adult patients, with coronary artery bridging, one case associated with coronary artery fistula, LAD to pulmonary artery trunk, very symptomatic with surgical management, and the second only myocardial bridging controlled with medication and supervision.

Background: Measurement of health-related quality of life (HRQOL) in children and adolescents with type 1 diabetes mellitus (T1DM) is as important as metabolic control in the management and prevention of diabetes-related complications. Aim: To describe the self-reported HRQOL outcomes in Ghanaian children and adolescents with T1DM compared with healthy controls and perceived HRQOL by caregivers.Setting: Out-patient clinics of the Departments of Child Health, Medicine and Therapeutics, Family Medicine, and Ophthalmology, the National Diabetes Management and Research Centre (all at the Korle Bu Teaching Hospital), and the Cape Coast Teaching Hospital (CCTH).Methods: Socio-demographic and clinical characteristics of study participants were documented. Participants completed the PedsQL™ 4.0 Generic Core Scales. Data analysis was done with SPSS Version 25.0. An unpaired t-test was used in comparing the HRQOL scores between children and adolescents with T1DM and controls, and parental proxy reports. Results: Fifty children and adolescents with T1DM, 50 parents/caregivers, and 80 healthy non-diabetic controls took part in this study. There was no significant difference in mean score between the patients and the caregivers for overall HRQOL (p = 0.270). Patients reported significantly worse overall HRQOL than their controls (p = 0.001). Males with diabetes reported better HRQOL than females (p = 0.007). Conclusion: Children and adolescents with T1DM and their parents/caregivers reported lower HRQOL scores compared to healthy controls. Males reported better HRQOL than females. Potential implications: HRQOL should be routinely assessed together with proxy reports from parents to identify those who might benefit from further attention including referral to a psychologist.

Hypochlorous acid (HOCl) is a potent antimicrobial agent that has recently gained attention as a potential alternative to conventional antibiotics. HOCl is produced by the human immune system in response to infection and is known for its broad-spectrum antimicrobial activity. It is effective against a wide range of microorganisms, including bacteria, viruses, and fungi, and has been shown to be more effective than many conventional antibiotics. One of the key advantages of HOCl is its ability to kill bacteria without promoting the development of antibiotic resistance. Unlike conventional antibiotics, which target specific bacterial structures or processes, HOCl acts by disrupting multiple cellular components, making it much more difficult for bacteria to develop resistance. Another advantage of HOCl is its safety profile. Unlike many conventional antibiotics, HOCl is not toxic to human cells and does not cause side effects such as gastrointestinal upset or allergic reactions. Overall, HOCl shows great promise as a potential alternative to conventional antibiotics, particularly in the face of rising antibiotic resistance. With further research, it may become an important tool in the fight against infectious diseases. Herein, we discuss the mechanisms of HOCl antimicrobial action, its potential clinical applications, and future directions for research. This review aims to provide an overview of the use of hypochlorous acid (HOCl) as an antibiotic agent.

Acute myeloid leukaemia (AML) is the forefront disorder of the bone marrow among others that disrupt the normal production of blood cells and platelets. The bone marrow microenvironment or the bone marrow niche (BM niche) that orchestrates the proliferation and survival of Leukaemic stem cells (LSC) is the reason for relapse after complete remission and also chemotherapy drug resistance. As for most cancers oxidative phosphorylation, a fundamental mitochondrial process of energy production, is under focus for the treatment of AML and a novel strategy of targeting heat shock proteins appears as a promising route for further research.

In summary it is an inspirational tool that hopefully will help our professional in physics out there.It interpretations and applications is subject to the personal inspirations the reader who is a professional can derived from the work for his or her personal usage.

Prescriptions for psychoactive substances such as Pregabalin, Methamphetamine, Caffeine, Clonazepam and Mirtazapine (PM-CCM) are common in the treatment of a variety of disorders. Indeed, the PM-CCM has been used in different therapeutic areas, including insomnia, anxiety, seizure disorders, etc. Unfortunately, these psychoactive substances are present in the illegal street market, leading to a lot of drug abuse among some addicted users, road insecurity and suicide. Hence, it has become essential to validate and develop a rapid and effective method to analyze the PM-CCM, a modified illicit drug, for drug abuse in the forensic sciences. A simple, rapid, specific and sensitive Gas Chromatography-Mass Spectrometry(GC-MS) method has been developed for the identification of Pregabalin, Methamphetamine, Caffeine, Clonazepam and Mirtazapine (PM-CCM) in forensic exhibits. At room temperature, the sample was ultrasonicated for 5 minutes before being extracted with methanol. A highly precise auto-injector is used to inject a very small quantity of samples for analysis. Helium is used as a carrier gas with a flow rate of 1 ml/min. The separation of PM-CCM was performed on SH-RXi-5 MS, ID.25 mm, film thickness. 25 µm, length of 30 m column. The constituents of PM-CCM were identified by the mass-to-charge ratio (m/z ratio) of fragments of the parent compound by comparing them with the NIST-17 MS Library. Separation and identification of PM-CCM were achieved within a 15-minute run. The proposed method has been successfully used for the routine analysis of PM-CCM in complex illicit drug preparations and in forensic exhibits as well. The application of above discussed qualitative analysis method and screening of PM-CCM, modified illicit drug samples demonstrates the potential and applicability of the technique to the fast chemical profiling of illicit samples.  

Central venous catheter fracture and migration are rare complications in patients receiving long-term infusions or chemotherapy. We present a rare case of a chest port catheter fracture that migrated into the coronary sinus. This case is likely the fourth report of a port catheter fracture with migration to the coronary sinus. Because of the difficult-to-retrieve location, multiple attempts were unsuccessful with traditional techniques using a loop snare. Finally, the fractured portion was disengaged from the coronary sinus using a navigational electrophysiology catheter guided by intracardiac echocardiography; the dislodged end was snared and eventually removed by the femoral route. This case of a chest port catheter fracture is unique because of the unusual migration to the coronary sinus and the use of a navigational electrophysiology catheter as a novel retrieval technique.

Cardiovascular diseases are the leading cause of mortality in the industrialized world. Among these diseases, aortic dissection affects the aorta wall and is a surgical emergency with a low survival rate. This pathology occurs when an injury leads to a localized tear of the innermost layer of the aorta. It allows blood to flow between the layers of the aortic wall, forcing the layers apart and creating a false lumen. Endovascular treatment seeks to obliterate the entrances to the false lumen with a covered stent. There are very few studies on the postoperative demonstration of blood flow phenomena in the aortic dissection endovascular treatment. It is crucial to study the hemodynamics of blood in the aorta after an intervention because the new geometrical configuration of the aorta with a stent leads to modifications in blood flow. For the surgeons, the procedure can only be performed empirically, using MRI-4D images to view the postoperative flow of the patient’s blood in the aorta with the stent.This paper aims to present a numerical tool developed from the open-source software FOAM- Extend®, allowing for multiphysics numerical simulations. Using MRI data, a bio-faithful model of the patient-specific case was built. Numerical simulations were performed to predict preoperative and postoperative (endovascular treatment) hemodynamics. The modifications of the flow in the aorta were analyzed focusing on the postoperative perfusions. The results were compared with the corresponding MRI data and have a good qualitative agreement. Biomarkers are calculated to localize possible zones of post-operative pathological developments and recommendations may be suggested to the surgeons.
