Ultrasound is a first-line and often preferred imaging modality in the diagnosis of acute appendicitis. When the appendix is not visualised during a dedicated appendix ultrasound study, patients may require a CT study, which uses ionising radiation, or undergo conservative clinical observation with the inherent risk of clinical deterioration, perforation and sepsis. Median baseline data, at our hospital imaging department, revealed a rate of combined normal and abnormal appendix visualisation of 34.

Colorless β-Au(μ-dppm)Br·2CHCl () has centrosymmetric structure with two three-coordinate gold(I) ions held in close proximity by the dppm ligands. Crystals of [Au(μ- dppm)Br]Br·2CHCl (), [Au(μ-dppm)Br](PF) (), and [Au(μ-dppm)Cl](BPh)·3CHCl () have a cation with an unusual arrangement that binds a two-coordinate gold(I) ion to a three-coordinate gold(I) ion through an aurophilic interaction.

Asian patients have different patterns of thrombotic and bleeding risk from other populations which may be particularly relevant in the setting of PPCI for STEMI.
Objectives: To assess the safety and efficacy of the polymer free biolimus coated coronary stent (PF-BCS, BioFreedom, Biosensors International) in Asian STEMI patients.
Article Synopsis
- Labial salivary gland biopsy (LSGB) is key for diagnosing primary Sjögren's syndrome (pSS), but traditional methods have drawbacks like larger incisions and clearer visibility issues during the procedure.
- A study compared a modified LSGB technique using chalazion forceps with the traditional method, involving 217 participants randomly assigned to each technique.
- The modified method resulted in smaller incisions, shorter surgery times, less bleeding, lower pain scores, and quicker healing, with no significant difference in biopsy results or final diagnoses between the two groups.
