[Undifferentiated embryonal liver sarcoma: case report and review of the literature].

Background: Undifferentiated embryonal sarcoma of the liver accounts for 9-13% of malignant tumors in the pediatric age group, and is the third primary malignant neoplasm of the liver in children. However, few cases are reported in the literature. It may manifest with fever, weight loss, pain, and abdominal tumor sensation.

Maternal cafeteria diet exposure primes depression-like behavior in the offspring evoking lower brain volume related to changes in synaptic terminals and gliosis.

Maternal nutritional programming by caloric exposure during pregnancy and lactation results in long-term behavioral modification in the offspring. Here, we characterized the effect of maternal caloric exposure on synaptic and brain morphological organization and its effects on depression-like behavior susceptibility in rats' offspring. Female Wistar rats were exposed to chow or cafeteria (CAF) diet for 9 weeks (pre-pregnancy, pregnancy, and lactation) and then switched to chow diet after weaning.

Recurrent renal cell carcinoma to the breast and thigh soft tissues. A case report and review of the literature.

The breast seldom harbors secondary malignant lesions and is rarer for the kidney to be the origin of the metastatic lesion. Keen Imaging analysis, as well as a high index of suspicion, are critical to differentiate a primary tumor from a metastatic lesion. We describe an unusual case of a recurrent RCC presenting as metastatic lesions to the breast and soft tissue of the right thigh in a 51-year-old patient referred to our breast-imaging unit 10 months after therapeutic surgery.

ADIPOQ single nucleotide polymorphisms and breast cancer in northeastern Mexican women.

Background: Adiponectin gene (ADIPOQ) polymorphisms have been shown to affect adiponectin serum concentration and some have been associated with breast cancer (BC) risk. The aims of this study were to describe the frequency of single nucleotide polymorphisms (SNPs) of ADIPOQ in Mexican women with BC and to determine if they show an association with it.

Methods: DNA samples from 397 patients and 355 controls were tested for the ADIPOQ gene SNPs: rs2241766 (GT) and rs1501299 (GT) by TaqMan allelic discrimination assay.

Respiratory distress associated with heterotopic gastrointestinal cysts of the oral cavity: A case report.

Heterotopic gastrointestinal cysts of the oral cavity are benign lesions usually discovered during infancy. Their pathogenesis is not very clear. They are rare congenital anomalies that result from remnants of foregut-derived epithelium in the head, neck, thorax or abdomen during embryonic development.

Fatal Outcome from Brain Vascular Lesions in a Neonate with Blue Rubber Bleb Nevus Syndrome.

The most common cause of death in blue rubber bleb nevus syndrome is gastrointestinal bleeding. Here we present a case of central nervous system bleeding that resulted in death.

Pediatric Papillary Renal Cell Carcinoma in a Horseshoe Kidney: A Case Report with Review of the Literature.

Renal cell carcinoma is the most common malignancy of the kidney in adults. In children, however, it only accounts for an estimated 1.8 to 6.

Population based prostate cancer screening in north Mexico reveals a high prevalence of aggressive tumors in detected cases.

Background: Prostate Cancer (PCa) is the second most frequent neoplasia in men worldwide. Previous reports suggest that the prevalence of PCa in Hispanic males is lower than in Africans (including communities with African ancestry) and Caucasians, but higher than in Asians. Despite these antecedents, there are few reports of open population screenings for PCa in Latin American communities.

A 5-year-old girl with a congenital ganglioneuroma diagnosed by fine needle aspiration biopsy: a case report.

Introduction: Ganglioneuroma is a rare, benign, neuroblastic tumor arising mainly from the central or peripheral autonomic nervous system, especially the sympathetic system. The most affected anatomical sites are the posterior mediastinum, retroperitoneum, adrenal gland and head and neck soft tissue. In the current literature, reports of ganglioneuroma diagnosed by fine-needle aspiration and its cytological appearance are scarce.
