Background: Patent ductus arteriosus (PDA) is a congenital heart defect that requires closure to prevent complications like heart failure and pulmonary hypertension. Catheter-based closure using devices such as the Amplatzer duct occluder is the preferred method due to its minimally invasive nature. However, device embolization is a rare but recognized complication, particularly in small children or high-flow PDAs.

Background: Rheumatic heart disease (RHD) continues to pose a significant burden on global health, particularly in socioeconomically disadvantaged populations. We present the case of a 38-year-old woman with severe multivalvular RHD and giant atria, highlighting the challenges and complexities of managing this condition.

Case Presentation: The patient presented with progressively worsening dyspnoea, signs of right heart failure, and severe valvular abnormalities.

A copper-catalyzed direct -Csp-H thiocyanation of free anilines has been developed. This method employs stable and non-toxic ammonium thiocyanate as a thiocyanation source, and -butyl hydroperoxide as the oxidant, enabling the synthesis of -thiocyanated anilines with good yields and broad substrate tolerance. Hitherto, no reports have been found in the literature for the -thiocyanation of aromatic amines, making this reaction an important breakthrough in synthetic organic chemistry.

Purpose: To compare dose volume parameters of target and organs at risk in vaginal vault brachytherapy using ovoids or cylinder in post-operative endometrial carcinoma.

Material And Methods: The study was done among 25 histologically proven post-operative endometrial carcinoma patients requiring vaginal brachytherapy. All patients underwent both cylinder and ovoids application alternatively on weekly basis.

Article Synopsis
  • The use of iron in catalysis is gaining attention due to its abundance, biocompatibility, and low cost, making it a strong alternative to expensive noble metals.
  • Direct C-H functionalization is a key method for adding new functional groups to organic molecules, which is crucial given the prevalence of C(sp )-H bonds in many compounds.
  • The review discusses the effectiveness, selectivity, and challenges of using iron catalysts in C(sp )-H activation, providing a summary of advancements up to 2022.
