Genome-wide approaches, such as whole-exome sequencing (WES), are widely used to decipher the genetic mechanisms underlying inter-individual variability in disease susceptibility. We aimed to dissect inborn monogenic determinants of idiopathic liver injury in otherwise healthy children. We thus performed WES for 20 patients presented with paediatric-onset recurrent elevated transaminases (rELT) or acute liver failure (ALF) of unknown aetiology.

Article Synopsis
  • The study aimed to evaluate the effects of adjuvant treatments and factors affecting recurrence and survival in patients with stage IIB endometrial cancer, using data from surgeries performed in Turkey between 2005 and 2022.
  • Out of 7323 patients, 565 were identified as stage IIB; most received adjuvant radiotherapy, but the study found no significant survival benefits from adjuvant treatments overall.
  • Notably, patients with tumors larger than 4 cm and myometrial invasion greater than 50% had higher recurrence rates, while adjuvant treatment improved overall survival only for those with deep myometrial invasion.

  • Pemphigus vulgaris (PV) is an autoimmune disease mainly affecting the mouth, leading to symptoms like burning sensations and oral erosions.
  • A study of 106 patients showed that most had the mucocutaneous subtype, with many experiencing severe symptoms that significantly impacted their quality of life.
  • Treatment often involved systemic steroids and rituximab, with a complete response seen in those taking rituximab, emphasizing the importance of monitoring the disease’s effects on patients' lives.

  • The study evaluated the impact of lumbar sympathetic block (LSB) on patients with lower extremity peripheral artery disease (PAD) for whom revascularization was not an option.
  • The review of 21 patients' medical records showed significant reductions in pain scores and improvements in the Fontaine Classification and collateral perfusion status after LSB treatment over six months.
  • Results indicated that LSB not only lowered pain levels but also improved blood flow by promoting neovascularization in many patients, with statistically significant findings at various follow-up points.

  • The study aimed to compare the success rates of sperm retrieval using microscopic testicular sperm extraction (mTESE) in men with non-obstructive azoospermia (NOA) who have either a solitary testis or bilateral testes.
  • A total of 74 patients from each group were analyzed for factors like age, infertility duration, and hormonal levels, with a focus on FSH and LH, as well as testicular volume.
  • Results showed similar sperm retrieval rates (54.1% for solitary and 56.76% for bilateral) but indicated higher levels of FSH and LH in those with a solitary testis; also, larger testicular size was linked to successful sperm retrieval in both groups.

Purpose: Osteoradionecrosis of the jaw (ORNJ) is a severe iatrogenic disease characterized by bone death after radiation therapy (RT) to the head and neck. With over 9 published definitions and at least 16 diagnostic/staging systems, the true incidence and severity of ORNJ are obscured by lack of a standard for disease definition and severity assessment, leading to inaccurate estimation of incidence, reporting ambiguity, and likely under-diagnosis worldwide. This study aimed to achieve consensus on an explicit definition and phenotype of ORNJ and related precursor states through data standardization to facilitate effective diagnosis, monitoring, and multidisciplinary management of ORNJ.

  • The study investigated the vaccination status and risk factors for ICU support among inpatients with breakthrough COVID-19 infections, categorizing them as fully or partially vaccinated.
  • A total of 516 patients were analyzed, revealing that hypertension, diabetes, and coronary artery disease were common comorbidities, with fully vaccinated patients showing a significantly lower need for ICU support.
  • The findings suggest that older age, specific health conditions, and incomplete vaccination increase the likelihood of requiring ICU care, highlighting the need for ongoing monitoring and booster vaccinations for at-risk populations.
