PURPOSE: The use of thyroidectomy has increased as a diagnostic technique for thyroid disease. However, performance of a, thyroidectomy is accompanied with complications. Post-thyroidectomy complications include recurrent laryngeal nerve palsy, hypocalcemia, hematoma, infection, and thyroid storm. The aim of this study was to determine the clinical incidence and to evaluate complications after a thyroidectomy, including recurrent laryngeal nerve palsy, hypocalcemia, hematoma, and scaring, following a retrospective review of cases. METHODS: From July 2004 to May 2006, 661 consecutive patients that had undergone a thyroidectomy were identified. Through a retrospective review, we evaluated the incidence and type of complications, including recurrent laryngeal nerve palsy, hypocalcemia, hematoma, and postoperative scaring. RESULTS: 1) Recurrent laryngeal nerve palsy was a very serious complication, but had a very low incidence. Eight cases out of 661 cases developed and most of the cases developed after a total thyroidectomy. 2) Hypocalcemia was the most common complication. Each incidence of hypocalcemia of methods of thyroid surgery was significant (P= 0.019) but, thyroid disease did not have significant difference (P=0.071). 3) The incidence of postoperative hematoma was 2.74% (18/655). Graves’ disease was more predominant than other diseases. CONCLUSION: Post-thyroidectomy complications and cosmetic problems include recurrent laryngeal nerve palsy, hypocalcemia, hematoma, and postoperative scar. An understanding of the incidence and review of complications after a thyroidectomy may reduce their incidence.

PURPOSE: Vaccine strategies utilizing dendritic cells (DCs) to elicit anti-tumor immunity are the subject of intense research. Although we have shown that DCs pulsed with heat-treated tumor lysate (HTL) induced more potent anti-tumor immunity than DCs pulsed with conventional tumor lysate (TL), the underlying molecular mechanism is unclear. In order to explore the molecular basis of this approach and to identify potential antigenic peptides from pancreatic cancer, we analyzed and compared the major histocompatibility complex (MHC) ligands derived from TL- and HTL-pulsed dendritic cells by mass spectrophotometry. MATERIALS AND METHODS: Human monocyte-derived dendritic cells were pulsed with TL or HTL prior to maturation induction. To delineate differences of MHC-bound peptide repertoire eluted from DCs pulsed with TL or HTL, nanoflow liquid chromatography-electrospray ionization-tandem mass spectrometry (nLC-ESI-MS-MS) was employed. RESULTS: HTL, but not TL, significantly induced DC function, assessed by phenotypic maturation, allostimulation capacity and IFN-gamma secretion by stimulated allogeneic T cells. DCs pulsed with TL or HTL displayed pancreas or pancreatic cancer-related peptides in context of MHC class I and II molecules. Some of the identified peptides had not been previously reported as expressed in pancreatic cancer or cancer of other tissue types. CONCLUSION: Our partial lists of MHC-associated peptides revealed the differences between peptide profiles eluted from HTL-and TL-loaded DCs, implying that induced heat shock proteins in HTL chaperone tumor-derived peptides enhanced their delivery to DCs and promoted cross-presentation by DC. These findings may aid in identifying novel tumor antigens or biomarkers and in designing future vaccination strategies.

The solitary fibrous tumor was a rare spindle cell tumor of adults that typically arised in the pleura, but also has been described in extrapleural sites.Recently, solitary fibrous tumors of the orbital soft tissue have been described. We confirmed a case of solitary fibrous tumor of lacrimal gland by histological and immunohistochemical examination in a 20-year-old female patient with left lateral upper eyelid mass.We report this case with literature review.

Recent amendments to regulatory frameworks have placed a greater emphasis on the utilization of in vitro testing platforms for preclinical drug evaluations and toxicity assessments. This requires advanced tissue models capable of accurately replicating liver functions for drug efficacy and toxicity predictions. Liver organoids, derived from human cell sources, offer promise as a reliable platform for drug evaluation. However, there is a lack of standardized quality evaluation methods, which hinders their regulatory acceptance. This paper proposes comprehensive quality standards tailored for liver organoids, addressing cell source validation, organoid generation, and functional assessment. These guidelines aim to enhance reproducibility and accuracy in toxicity testing, thereby accelerating the adoption of organoids as a reliable alternative or complementary tool to animal testing in drug development. The quality standards include criteria for size, cellular composition, gene expression, and functional assays, thus ensuring a robust hepatotoxicity testing platform.
