RTT girls suffer periods of abnormal behavior from early infancy, including irritability and sleep disorders or anxiety in the first years of life, and a more depressed mood after adolescence, all of which influences their quality of life. An association between emotional and behavioral disorders and various neurochemical changes in the synapses of cortical and subcortical brain regions has been established;also, cortisol levels in the blood vary during stress. The main purpose of this study was to improve mood and behavior disorders in RTT patients with venlafaxine (SNRI), and compare the results with citalopram (SSRIs) during 6 - 8 weeks, to determine which drug offered greater efficacy and fewer side effects, as well as to compare them to risperidone, and to correlate cortisol levels in saliva with stress and drug response. Eleven patients, aged 5 to 26 years old, agreed to participate in this study;neuropsychological tests (Mullen and Vineland scales), quality of life and quality of sleep scales, blood tests, EKG and EEG were performed before and after treatment. Only 2 patients completed the three months trial. Improvement in mood and behavior was not statistically significant for patients;differences in neurodevelopment and quality of life or sleep scales were not significant either;no serious adverse effects were observed. Cortisol levels in saliva decreased in 50% of the patients after the first month of treatment, although this was not statistically significant.

Steatosis recovery after treatment with a balanced sunflower or olive oil-based diet: Involvement of perisinusoidal stellate cells

引用

World Journal of Gastroenterology 2005年第47期11卷 7480-7485页

作者： Raquel Hernández Esther martínez-Lara ana Cauelo Ma Luisa del Moral Santos Blanco Eva Siles ana Jiménez Juan ngel Pedrosa Ma ngeles Peinado Department of Experimental Biology University of JaénParaje Las Lagunillas s/nE-23071 JaénSpain

AIM： To analyze the relationship between perisinusoidal stellate cell （PSC） activation and the dietary fat quantity and composition in the treatment of hepatic steatosis. METHODS： Using an experimental rat model of steatosis based on the intake of a hyperlipidic diet （14% fat as olive oil or sunflower oil, HL-O and HL-S, respectively）, we analyzed the liver＇s capability of recovery after the treatment with a normal-lipidic diet （5% fat as olive oil or sunflower oil, NL-O and NL-S, respectively） by immunoo/tochemical and Western blot analysis of glial fibrillary acidic protein （GFAP） expression in PSCs, collagen quantification and serum aminotransferase determination. RESULTS： The fatty infiltration in the steatotic livers decreased after the treatment with both NL diets, indicating liver recovery. This decrease was accompanied with a lower collagen deposition and aminotransferase level as well as changes in the PSC population that increased the GFAP expression. The above-mentioned effects were more pronounced in animals fed on NL-O based diet. CONCLUSION： Treatment with a balanced diet enriched in olive oil contributes to the liver recovery from a steatotic process. The PSC phenotype is a marker of this hepatic-recovery model.

Pancreatic adenosquamous carcinoma and intraductal papillary mucinous neoplasm in a CDKN2A germline mutation carrier

作者： Fernando martínez de Juan María Reolid Escribano Carmen martínez Lapiedra Fernanda Maia de Alcantara María Caballero Soto ana Calatrava Fons Isidro Machado Gastroenterology and Digestive Endoscopy Department Valencian Institute of Oncology Digestive Surgery Department Valencian Institute of Oncology Pathology Department Valencian Institute of Oncology

A 69-year-old woman from a kindred with familial atypical multiple mole melanoma and carrier of a germline mutation in CDKN2A, presented with abdominal pain caused by a solid-cystic pancreatic mass. The patient had an abdominal computed tomography three years before in which there was no evidence of pancreatic lesion. The endoscopic ultrasound guided fine needle aspiration showed adenocarcinoma with squamous component. After surgical resection the final diagnosis was adenosquamous pancreatic carcinoma(ASPC) arising in an intraductal papillar mucinous neoplasm(IPMN). Adenosquamous carcinomas are uncommon in the pancreas and have rarely been described in association with IPMNs. It has worse prognosis than the ordinary pancreatic ductal adenocarcinoma and some distinct features. We review the clinical, imaging, pathologic and molecular aspects of ASPC. Differential diagnosis with contamination, squamous metaplasia and pancreatic metastases from a distant squamous carcinoma is discussed. Besides, the case is an accelerated model of the adenoma(IPMN)-carcinoma sequence probably due to the CDKN2A ger-mline mutation. Somatic CDKN2A mutations are commonevents in the early steps of sporadic pancreatic cancer, but germline mutation carriers have a significantly higher risk of pancreatic carcinoma.

Most recent studies on regeneration of inner ear hair cells focus on use of stem cells, gene therapy and neurotrophic factors. Cochlear gene therapy has been successfully used in the treatment of neu- rosensory hearing loss. This suggests that cochlear hair cell regeneration is possible. The objective of this paper is to review research and clinical application of inner near hair cell regeneration.
