Article Abstract
Malignant proliferating trichilemmal tumor (MPTT) is thought to represent the malignant counterpart of benign proliferative pilar cyst, a lesion originating from the outer hair root sheath. We report a case of an 86-year-old woman with an exophytic nodule containing an ulcerated surface in the temporal region. Histopathologically confirmed MPTT without metastasis, and considering the risk of metastasis and recurrence, we used single local narrow margin excision combined with modified 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT). No recurrence of skin lesions was found in the 2-year follow-up after combined therapy. In conclusion, local narrow margin excision sequential with modified ALA-PDT may be a particularly promising and effective treatment option for MPTT.

Advancing breast cancer and lung cancer screening: Expert perspectives to advance programmes in Singapore.
Ann Acad Med Singap

Division of Medical Oncology, National Cancer Centre Singapore, Singapore.
Introduction: The high prevalence and mortality rates of breast cancer and lung cancer in Singapore necessitate robust screening programmes to enable early detection and intervention for improved patient outcomes, yet 2024 uptake and coverage remain suboptimal. This narrative review synthesises expert perspectives from a recent roundtable discussion and proposes strategies to advance breast cancer and lung cancer screening programmes.
Method: A 2024 roundtable convened clinical practitioners, health policymakers, researchers and patient advocates discussed current challenges and opportunities for improving cancer screening in Singapore.

A 48-year-old man with a superior labral tear and medical history including hemidiaphragmatic paresis, obstructive sleep apnea, vocal cord paresis, and glottic narrowing, underwent arthroscopic biceps tenodesis. Reduction in respiratory function presented anesthetic management challenges with general anesthesia or an interscalene brachial plexus block. Instead, ultrasound guidance was used to deliver a selective upper-trunk block with 1 % lidocaine and an axillary nerve block with 0.

Local pH variations play a pivotal role in numerous critical biological processes. However, achieving the tunability and selectivity of pH detection remains a challenge. Here, we present a DNA-based strategy that enables programmable and selective pH responses, which is termed shadow-strand hybridization-actuated displacement engineering (SHADE).

Modulating the electronic structure of catalysts to maximize their power holds the key to address the challenges faced by zinc-iodine batteries (ZIBs), including the shuttle effect and slow redox kinetics at the iodine cathode. Herein, oxygen vacancies is innovatively introduced into CoO lattice to create high-spin-state Co active sites in nonstoichiometric CoO nanocrystals supported by carbon nanofibers (H-CoO/CNFs). This simple strategy intensifies crystal field splitting of Co 3d orbitals, optimizing the spin-orbital coupling between Co 3d orbitals and iodine species.

Purpose: To evaluate changes in implant stability quotient values of hydrophilic tissue-level implants over time, and to investigate the influence of local factors on variations in these values.
Methods: Fifty tapered, self-tapping, tissue-level implants with a hydrophilic surface were placed and monitored for 12 months. Implant stability quotient values were recorded at the time of insertion (T0) and monthly thereafter for 12 months.
