Optimizing aesthetic results in Asian women with giant phyllodes tumors over 10 cm: the periareolar mastopexy approach.

Giant phyllodes tumors, typically exceeding 10 cm in size, are neoplastic lesions with malignant potential. Surgical excision in small-breasted Asian women presents unique challenges where expected poor aesthetic outcomes may delay timely medical intervention. The periareolar mastopexy technique offers a comprehensive solution, enabling complete tumor removal alongside mastopexy to achieve optimal breast contouring.

Using the proximal perforator-based anterolateral thigh flap from the same donor site to salvage the reconstruction after failure of the distal perforator-based anterolateral thigh flap.

We presented a patient who experienced the anterolateral thigh (ALT) flap failure but the reconstruction was successfully salvaged by harvesting a second ALT flap from the same donor site 2 days after the first reconstruction. A 47-year-old man received cancer ablation for right mouth floor squamous cell carcinoma. The resultant defect was planned to be reconstructed with the ALT flap.

Rapid analysis of abused drugs using nanostructured silicon surface assisted laser desorption/ionization mass spectrometry.

This study developed a rapid, sensitive, and matrix-free method for the determination of amphetamine (AMP), methamphetamine (MA), codeine (COD), morphine (MOR), and ketamine (KET) using nanostructured silicon surface assisted laser desorption/ionization mass spectrometry (nSi-MS). The nanostructured silicon (nSi) chip used in this study was created by employing the metal-assisted etching process. Drug standard tests were applied to the nSi chip platform to evaluate the nSi-MS performance, including detection sensitivity, limit of detection, linearity, and repeatability.
