Frequency of various types of neoplasia in a group of acromegalic patients

OBJECTIVE: To determine the frequency of colon cancer, primary hyperparathyroidism, thyroid tumor, and skin cancer in all acromegalic patients in follow-up at the Clinics Hospital - Botucatu Medical School, from 2005 to 2011. SUBJECTS AND METHODS: These patients were evaluated retrospectively for colon cancer, primary hyperparathyroidism, dermatological, and thyroid tumors. RESULTS: Of 29 patients included at the beginning of the study, two were excluded. Among 19 patients submitted to colonoscopy, one presented colon adenocarcinoma (5%). Thyroid nodules were present in 63% of patients, and papilliferous carcinoma was confirmed in two patients (7,7%). Four patients were confirmed as having primary hyperparathyroidism (15%). The most common dermatologic lesions were thickened skin (100%), acrochordons (64%), epidermal cysts (50%), and pseudo-acanthosis nigricans (50%). Only one patient presented basal cell carcinoma. CONCLUSION: Although a small number of acromegalic patients was studied, our findings confirm the high frequency of thyroid neoplasias and primary hyperparathyroidism in this group of patients.

Ultrastructural features of spermatogenesis in Melanorivulus punctatus (Cyprinodontiformes: Rivulidae)

Fish belonging to the family Rivulidae possess one of the most complex reproductive systems. Rivulus, a genus of freshwater fish in the Rivulidae family, was recently reclassified into five genera, including Melanorivulus. Its type species, M. punctatus, is widely distributed and probably represents a species complex. The ultrastructure of sperm has been broadly used in systematics, and we hereby describe the ultrastructural features of spermatogenesis in M. punctatus. Ten M. punctatus males were collected from the reservoir of Parque Estadual da Quineira, municipality of Chapada dos Guimardes, Mato Grosso, Brazil, and prepared for analysis by light microscopy and transmission electron microscopy. M. punctatus undergoes cystic spermatogenesis. Its cysts consist of groups of germ cells that are in synchronous development and are surrounded by cytoplasmic projections of Sertoli cells. With the breakdown of the cysts, the spermatozoa are released and their maturation is completed in the duct, where part of the cytoplasmic material is discarded through the vesicles. The mature spermatozoon is characterized by a spherical head with homogeneously condensed chromatin, a symmetric midpiece consisting of a pair of perpendicular centrioles, a ring of mitochondria, several vesicles, and one flagellum medial to the nucleus. Early stages of spermatogenesis show no peculiarities; however, in spermiogenesis, we observed that the spermatids remain interconnected by cytoplasmic bridges and have pockets of residual cytoplasm. The sperm is of the aquasperm type and is similar to that observed in the members of the family Rivulidae. The spermatozoa have a single flagellum that consists of a classic axoneme (9 +2), as found in most groups of fish, despite the lateral extensions. (c) 2014 Elsevier Ltd. All rights reserved.
