The coronary sinus (CS) is the venous drainage system of the heart. CS ostium atresia is a rarely seen cardiac malformation. Congenital atresia of the CS is usually found together with persistent left superior vena cava (LSVC) and other cardiac malformations. However, isolated congenital atresia of the CS is very rare. We present a rare case of isolated congenital atresia of the CS connecting the left atrium and coronary veins without persistent LSVC in a 58-year-old female.

Background: In middle-income countries, healthcare systems face unique challenges in ensuring timely antenatal detection of congenital abnormalities that require pediatric surgical intervention. Early detection can significantly improve outcomes, yet resource constraints often limit access to diagnostic technologies. This study evaluates the antenatal detection rate of congenital abnormalities referred to pediatric surgical services in three Malaysian tertiary centers and examines its effect on maternal anxiety.

Worldwide, congenital deafness and pigmentation disorders impact millions with their diverse manifestations, and among these genetic conditions, mutations in the Microphthalmia-associated transcription factor (MITF: OMIM#156845) gene are notable for their profound effects on melanocyte development and auditory functions. This study reports a novel porcupine model exhibiting spontaneous deafness and pigmentation abnormalities reminiscent of human Waardenburg Syndrome Type 2 (WS2: OMIM#193510). Through phenotypic characterization, including coat color, skin, eye morphology, and auditory brainstem response (ABR) assessments, we identified hypopigmentation and complete deafness in mutant porcupines.

BACKGROUND Arterioportal fistulas (APFs) are abnormal connections between the arterial and portal venous systems, leading to portal hypertension (PH) and symptoms such as gastrointestinal bleeding, splenomegaly, and hepatic pain. Symptoms typically appear by the age of 2 years in about 75% of cases. CASE REPORT A 7-year-old boy with an asymptomatic APF developed life-threatening complications following a Clostridium difficile infection.

Congenital radioulnar synostosis (CRUS) presents a complex forearm deformity, requiring precise osteotomy planning for anatomical restoration. This study proposes an automatic osteotomy preoperative planning method for forearms with CRUS. Proximal forearm bones are first aligned with the template forearm and then a dual dimensional optimization (DDO) strategy is used to optimize the spatial transformation parameters of the distal fragment.
