Improvements in preoperative diagnostic modalities in conjunction with highly sensitive calcitonin assays, ultrasound and functional imaging modalities and differentiated genetic testing for detection of hereditary forms, have enabled detection and resection of medullary thyroid carcinoma at an increasingly earlier stage. These developments open up possibilities to deescalate primary surgery adapted to these stages and avoid surgical overtreatment in locally limited tumor growth thus, promoting a shift from routinely recommended total thyroidectomy with bilateral central lymph node dissection in favor of limited unilateral thyroid resection. Prerequisites for limited thyroid resection include clinical evidence that the tumor is sporadic, unifocal and confined to the thyroid. Corresponding calcitonin levels should also indicate that a biochemical cure will be achieved after unilateral resection. A decisive structural prerequisite for such a limited concept is the low threshold availability of intraoperative frozen section analysis that reliably detects and evaluates a medullary thyroid carcinoma and can assess a breach of the thyroid capsule and desmoplasia with certainty.In this study, we have analyzed 23 Y-chromosomal short tandem repeats (Y-STRs) (DYS576, DYS389I, DYS389II, DYS448, DYS19, DYS391, DYS481, DYS549, DYS533, DYS438, DYS437, DYS570, DYS635, DYS390, DYS439, DYS392, DYS643, DYS393, DYS458, DYS460, DYS385ab, DYS456 and Y-GATA-H4) in 175 father-son sample pairs using a Microreader™ 24Y Direct ID system. Sixteen repeat mutations of father-son pairs at 10 loci, including three mutations at DYS570, 2 mutations at DYS549, DYS460, DYS458, and DYS576, and 1 mutation at other five loci, were revealed. Furthermore, all of the observed repeat mutations were single repeat changes with 5 (31.25%) repeat insertions and 11 (68.75%) repeat deletions. The deletion rate is more than two fold higher than of insertions (115 = 2.2-fold). Locus-specific mutation rates estimated varied between 5.71 × 10-3 (CI from 0.1 × 10-3 to 31.4 × 10-3) and 1.71 × 10-2 (CI from 3.6 × 10-3 to 49.3 × 10-3) for the 23 Y-STRs. CC-5013 An average mutation rate across all 23 Y-STR markers was estimated as 3.97 × 10-3 (CI 2.3 × 10-3 to 6.4 × 10-3). Thus, locus-specific mutation rates in DYS460, DYS458, and DYS438, estimated are much higher than previously published comprehensive data, but an average mutation rate across all 23 Y-STR markers is similar to previous reports (3.97 × 10-3 vs 4.34 × 10-3). These results by characterizing Y-STR mutations will not only provided new information for Y-STR mutations but also might be important for paternal lineage identification, kinship analysis, and family relationship reconstruction in our forensic Y-STR analysis.This study aims to investigate the apoptotic and anti-angiogenic effect of Zoledronic acid on hormone-refractory prostate cancer cell lines. XTT cell proliferation assay used to assess cytotoxicity. Caspase 3/7 activity and DNA fragmentation were measured to verify apoptosis. Angiogenic cytokine profiles investigated using the human angiogenesis antibody array I. Administration of Zoledronic acid on PC-3 and DU-145 prostate cancer cell lines resulted in increased cytotoxicity and apoptosis with a time- and dose-related manner. Also, the administration of Zoledronic acid significantly reduced several angiogenic cytokine productions in PC-3 and DU-145 cell lines. Zoledronic acid successfully induced apoptosis and reduced various angiogenic cytokine production in hormone-refractory prostate cancer cell lines. Novel treatment protocols may be developed in the future with chemotherapeutic combinations for the treatment of prostate cancer.

Gangliogliomas are neoplastic lesions composed by a mixed population of neoplastic glial and dysplastic neural cells. They represent around 5% of all CNS tumors in the pediatric population. These usually are well-differentiated, slow-growing tumors, meaning that complete resection could cure most of these patients. Although most lesions remain stable over time after incomplete resection, some patients develop progression of the residual lesions the optimal approach to treat these tumors is still to be defined.

This is a retrospective study in which we obtained data from medical records of pediatric patients who had a histological diagnosis of ganglioglioma following surgical treatment at a single center between 2001 and 2020.

We included 17 pediatric subjects with gangliogliomas. The median age at diagnosis was 6.7 years, and the median follow-up duration was 60 months. The most common clinical presentation was epileptic seizures (41.1%). Hydrocephalus was present in 29.4% of cases. 52.9% of tumors invocally grade I tumors that occasionally affect children. They classically localize in the cerebral hemisphere but may involve deep structures like the basal ganglia, brain stem, and cerebellum, which seems to be particularly frequent in the pediatric population, implying further challenge to achieve adequate oncological control with surgery as the only treatment modality. Although most cases in which GTR could not be performed remained stable over the follow-up, significant progression of the tumor remains was observed in some patients. BRAF inhibitors should be considered as a feasible treatment option in this setting.

Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor of intermediate malignancy with tendency for local invasion and recurrence. The tumor almost exclusively occurs in children, especially in infants. Intracranial KHE are extremely rare with only two cases reported in the literature.

We report the clinical and pathological features of this rare tumor arising from basitemporal region in a 21-month child. Our case did not present with Kasabach-Merritt phenomenon. Histopathological examination confirmed the diagnosis of KHE.

KHE should be considered in the differential diagnosis of intracranial extra-axial neoplasm in children, and histopathological examination plays an important role in distinguishing KHE from its morphologic mimics. It is essential to diagnose KHE due to its locally aggressive nature.
