Skin adnexal carcinoma of the eyelid: A case report.

Skin adnexal carcinomas (SACs) represent a diverse range of cancerous growths originating from the appendages of the skin. SACs are exceedingly rare malignancies that primarily manifest in individuals with fair skin and predominantly affect the head and neck. In the present study, a 70-year-old male presented with swelling and redness around the right eye, accompanied by skin desquamation.

Intratesticular prepubertal‑type mature teratoma in an infant: A case report and mini‑review of the literature.

Testicular tumors are rare in children, representing a small percentage of pediatric solid tumors, with an incidence of 2 cases per 100,000 males. Teratomas, which are the most prevalent tumors in infants, may manifest in mature, immature, or malignant forms. While mature teratomas are typically found in the abdomen, intratesticular prepubertal-type teratomas in infants are infrequent.

Concurrent squamous cell carcinoma and non-hodgkin lymphoma: a rare case report and multidisciplinary approach.

Introduction: Squamous cell carcinoma (SCC) is a skin malignancy typically treated with surgical resection. Non-Hodgkin lymphoma (NHL) is a group of lymphoid tissue malignancies treated with various strategies, including chemotherapy and radiotherapy.

Case Presentation: A 64-year-old male with prior SCC presented with a new scalp lesion.

Predictive value of inflammatory markers for the spontaneous passage of Ureteral stones: a comprehensive systematic review with meta analysis.

Urolithiasis is a common disease that affects approximately one-fifth of the global population. This systematic review explores the predictive role of inflammatory markers for the spontaneous passage of ureteral stones. The literature was systematically searched via Google Scholar, PubMed/MEDLINE, the Cochrane Library, Science Direct, CINAHL, Web of Science, and EMBASE databases to identify papers published until 2023.

Spermatocytic tumor of the testis: A case report and mini‑review of the literature.

Spermatocytic tumors are a rare type of testicular cancer, comprising <1% of all testicular malignancies. This type of cancer typically affects males in their 60s and 70s and rarely metastasizes; however, it poses a threat to the health of affected individuals if left untreated. The present study describes the case of a 68-year-old male patient with this type of tumor, including a presentation of his initial symptoms, treatment and subsequent monitoring.

Gastroesophageal adenocarcinoma metastasizing to the chest wall: A case report and mini‑review of the literature.

Subcutaneous metastasis from esophageal cancer (EC), particularly to the chest wall, is a very rare phenomenon. The present study describes a case of gastroesophageal adenocarcinoma that metastasized to the chest wall, invading the fourth anterior rib. A 70-year-old female presented with acute chest pain 4 months after undergoing Ivor-Lewis esophagectomy for gastroesophageal adenocarcinoma.

Primary pancreatic synovial sarcoma: Report of a rare case and review of the literature.

Synovial sarcoma is a mesenchymal spindle cell tumor. Primary pancreatic sarcomas are extremely rare. The present study describes a rare case of synovial sarcoma in the head of the pancreas.

Preparation and characterization of dexamethasone lipid nanoparticles by membrane emulsification technique, use of self-emulsifying lipids as a carrier and stabilizer.

Self-emulsifying lipids (SEL) were used as a stabilizer for the preparation of dexamethasone lipid nanoparticles by membrane emulsification employing Shirasu porous glass. The effect of process and formulation parameters on the size and polydispersity and dexamethasone solubility in lipids and its release from lipid nanoparticles were investigated. Lipid phase pressure (40-80 kPa), membrane pore-size (0.

Use of cellulose acetate butyrate as a carrier for preparation of alcohol-resistant matrix tablet.

The objective of this study was to investigate cellulose acetate butyrate (CAB) as a carrier for extended-release alcohol-resistant matrix tablet. Powder blends were either directly compressed or granulated before compression. The drug release from CAB matrix tablet was robust to formulation/process parameters such as compression force (10-20 kN), granular size (0.

Quantification of porogen effect on the drug release from single- and multi-layered ethylcellulose coated pellets containing single or combined drugs.

The aim of this work was to develop a mathematical model to estimate the drug release from a conventional single-compartment reservoir pellet and extend its applicability to multi-compartment reservoir pellets. Conventional pellets were prepared by layering the drug onto starter-core then applying various ethylcellulose/HPC coatings for drug release control. Multi-layered pellets comprised a first drug layer of propranolol HCl (D) followed by a first controlled release coating (C) and consecutively a second drug layer of carbamazepine or caffeine (D) and then a second controlled-release coating (C).

Water-insoluble polymers as binders for pellet drug layering: Effect on drug release and performance upon compression.

The objective of this study was to investigate the applicability of water-insoluble polymers as binders for pellet drug layering to extend the drug release. Carbamazepine was layered on sugar cores in fluidized bed coater using isopropanol (IPA):water solution or aqueous dispersion of ethylcellulose, polyvinyl acetate or ammonium-methylmethacrylate copolymer. Carbamazepine release was extended with all investigated water-insoluble polymers used as binder, without an additional coating layer.

Release Adjustment of Two Drugs with Different Solubility Combined in a Matrix Tablet.

The objective of this study was to modify the release of two drugs having different solubility in a combined matrix tablet as a fixed-dose combination for extended release. Propranolol HCl (freely soluble) and carbamazepine (very slightly soluble) were used as model drugs, water-soluble hydroxypropyl methylcellulose (HPMC) and water-insoluble ethylcellulose (EC) were used as matrix-forming polymers. Tablets were prepared by direct compression of powder blends, or propranolol HCl was first granulated with one of the matrix-forming polymers (1:1) followed by compression with carbamazepine and matrix former.
