Amphetamine, methamphetamine, and MDMA in hair samples from a rehabilitation facility: Validation and applicability of HF-LPME-GC-MS.

Introduction: It is known that drug abuse jeopardizes economic and social development. Toxicological analyses can guide prevention and treatment strategies in rehabilitation facilities. The current greatest challenge is finding easily adaptable and less costly sensitive methods that meet the principles of green chemistry.

Histological and immunohistochemical characteristics and status studied by FISH in six incidentally detected cases of well-differentiated papillary mesothelioma of the peritoneum.

Well-differentiated papillary mesothelioma (WDPM) is an uncommon mesothelial neoplasm, which is generally regarded as benign or indolent in terms of its clinical behavior. However, details about WDPM have remained relatively unknown. Therefore, in this study, we examined six incidentally detected cases of WDPM of the peritoneum.

Nevus lipomatosus cutaneous superficialis on the shoulder: A case report with MRI findings.

Nevus lipomatosus cutaneous superficialis is a rare disease, and its magnetic resonance imaging features have not been reported. A 1-year-old male infant was admitted to our hospital for examination of a mass on his right shoulder. Magnetic resonance imaging revealed hypertrophic skin and a lipomatous subcutaneous mass, consistent with a hamartoma-like lesion or mesenchymal tumor; after surgery, the tumor was pathologically diagnosed as nevus lipomatosus cutaneous superficialis.

[A case of non-invasive IPMC with fibrotic lesion-like "tubular complex"].

A 73-year-old man was incidentally diagnosed with a cystic lesion in the pancreatic body. Ultrasonography, abdominal computed tomography, magnetic resonance imaging, endoscopic retrograde cholangiopancreatography, and endoscopic ultrasound were performed, and a nodule was detected in the cystic lesion along with an irregularity of the main pancreatic duct. An initial diagnosis of a mixed-type intraductal papillary mucinous neoplasm was made, and a central pancreatectomy was performed.

Gastric cancer metastatic to neck lipoma: a case report with imaging consideration.

A 71-year-old man visited our hospital for examination of a soft neck mass. Computed tomography and magnetic resonance imaging scans showed a well-circumscribed large lipomatous tumor with multiple nodules inside. Atypical lipomatous tumor or lipoma involving the lymph nodes was considered.
