BACKGROUND: Simulation-based medical education has been growing rapidly and becomes one of the most popular teaching methods for improving patient safety and patient care. The Simulation Subcommittee of the Hong Kong College of Emergency Medicine organized an educational program emphasizing the team training, clinical decision-making and communication skills. This study aimed to evaluate the attitude of the participants toward a new training program and the change in the knowledge on clinical performance in emergency physicians and nurses after attending the educational program. METHODS: A course evaluation form was filled in by the participants at the end of the workshop. An assessment of 20 multiple-choice questions with 5 options was administered to the participants before and after the 2-day simulation-based training workshop. RESULTS: A total of 72 doctors and nurses working in the Accident and Emergency Department were enrolled. The average pretest and posttest scores were 12 and 14.3 respectively. The percentage improvement in the mean score of the pretest and posttest was 11.5%. The Chi-square test showed significant improvement in the pretest and posttest score grading (P=0.00). Paired t-test revealed significant difference between the mean scores of the pretest and posttest (P=0.00). CONCLUSIONS: Participants had positive attitude toward this new training program. Significant improvement of the knowledge on clinical performance in healthcare professionals in the Accident and Emergency Department was observed after the participation in this simulation-based educational program.

Histopathological diagnosis of brain stem glioma should be performed for the purpose of the determination of its management and clinical course, but its surgical biopsy has been followed by high mortality and morbidity. We performed the tissue sampling for histological examination with BRW stereotaxic system under local anesthesia successfully.

Korean Journal of Anesthesiology 2025;78(3):279-284
Background:
Current regional anesthesia techniques used to anesthetize the intercostobrachial nerve (ICBN) for upper arm surgery either lack reliability or have increased procedural risks. Safer and more reliable regional anesthetic techniques are required to block the ICBN effectively. Here, we introduce a novel “axillary serratus anterior plane (A-SAP) block” for anesthetizing the ICBN to allow surgical anesthesia for upper arm arteriovenous fistula (UA-AVF) creation. Case: We present 3 cases involving a 79-year-old Chinese male, a 73-year-old Malay female, and a 38-year-old Chinese male, in which the A-SAP block was utilized in UA-AVF creation surgeries. In all 3 cases, the A-SAP block was performed in combination with a supraclavicular brachial plexus block. None of the patients required local anesthetic supplementation intraoperatively.
Conclusions
The A-SAP block reliably and safely anesthetized the ICBN for UA-AVF creation surgery and is a reliable alternative to higher-risk block techniques, such as paravertebral block or neuraxial block.

Job's syndrome is an inflammatory skin disease characterized by (1) severe eczema, (2) recurrent staphylococcal infections of the skin and sinopulmonary tract, (3) cold subcutaneous abscesses, and (4) high serum IgE levels. We describe a 55-year-old woman with long-standing atopic dermatitis-like eczema, recurrent abscesses, and a high level of serum IgE. We suspected this case as Job's syndrome.

Congenital self-healing reticulohistiocytosis (CSHRH) is a rare Langerhans cell disorder showing spontaneous resolution within 3-4 months. By electron microscopy, the identification of many Birbeck granules and laminated dense bodies in the infiltrated cells is mandatory for the diagnosis of CSHRH. We describe a case of congenital self-healing reticulohistiocyt~osis in a 4-month-old male infant.

A case of primary cutaneous CD30(Ki-1)-positive pleomorphic large cell lymphoma in a 51-year-old woman with generalized lichen myxedematosus is presented. Histopathological findings of the biopsy specimens from the lichenoid papules of the left forearm and the dorsum of the right hand were compatible with papular mucinosis. The mucinous material in the papillary dermis stained with alcian blue at pH 2.5 and was susceptible to hyaturonidase, but serum protein electrophoresis showed no abnormal bands and an abnormal paraprotein was not detected in our patient. Histopathological examination of a solitary, firm, purplish nodule on the right popliteal area showed diffuse and extensive infiltration in the reticular dermis composed of large, atypical, often hyperchromatic, sometimes multinucleated and markedly pleomorphic cells. The majority of the large atypical cells were CD30(Ki-1) positive. The TCR gene re-arrangement analysis demonstrated the presence of a monoclonal rearrangement of the y-TCR gene in the skin biopsy specimen of our patient. The organ-system survey revealed no evidence of internal organ involvement. We concluded that this was primary cutaneous CD30(Ki-1)-positive pleomorphic large cell lymphoma developing in a patient with generalized lichen myxedematosus.

The Sturge Weber syndrome is an uncommon disorder characterized by port-wine nevus of the face with angiomatosis of the ipsilateral cerebral leptomeninges and extensive calcification in the underlying cerebral cortex. Associated with this syndrome are mental retardation, choroidal angioma, buphthalmus or glaucoma, seizure and hemiplegia. We studied a case of incomplete form of Sturage Weber syndrome in a 12 year-old boy, who had generalized seizure, a homonymous hemianopsia, intracranial calcification and leptomeningeal angiomatosis. There are no characteristic facial nevus, mental retardation, occular changes and hemiplegia.
