Secondary pathologic fractures in osteosarcoma: prognosis and evolution.

Secondary or pathologic fractures, associated with osteosarcoma, have been considered for a long time to be a negative prognosis regarding its evolution in the patients. The aim of this study was to evaluate the prognostic importance of such pathologic fractures in osteosarcoma patients receiving new therapies as well as the best conditions for surgery aiming at "limbs salvage". On a total of 22 patients affected by osteosarcoma, we performed a retrospective study with 12 patients showing pathologic fractures caused by osteosarcoma and 10 patients without any pathologic fracture. The patients enrolled into Timisoara University Hospital have been followed up along 5 years or until a reappearance of either the disease or metastases, distant or local.

An unusual foreign body in the upper aerodigestive tract: esophageal obstruction due to bran impaction.

Foreign bodies of the upper aerodigestive tract are common problems encountered by the otolaryngologist and general surgeons. While the diagnosis seems straightforward, it is sometimes delayed until after serious complications have occurred. The treatment of choice is endoscopic retrieval under general anesthesia. The procedure should be preceded by the completion of appropriate studies (radiographic and other specifically indicated for the patient) planned and performed by the endoscopy team. Time invested in preparation and planning will usually yield a speedy recovery of the patient. Bran is a natural fiber that undergoes considerable expansion and thickening when hydrated. Due to this property, it has been used in "weight loss" tablets that in the stomach undergo expansion and are expected to cause early satiety. These tablets are usually marketed as over-the-counter (OTC) diet products by a number of pharmaceutical manufacturers. These supplements consisting primarily of dietary fibers, so common and inoffensive-seeming, rarely may have severe side effects, such a sudden esophageal obstruction. We report a case of a bran dietary product impacted in the cervical esophagus in a 45 year old woman, presenting as an emergency complaining of retrosternal discomfort and difficult to swallow or drink. The technique for removal of such object that is also reported.

Effects on rat sexual behaviour of acute MDMA (ecstasy) alone or in combination with loud music.

The effects on sexual behaviour of acute low doses of methylendioxymethamphetamine (MDMA) (0.3, 1, 3 mg/kg/i.p.), alone or in combination with exposure to loud music (1 h stimulation), were investigated in Wistar rats. Results indicate that acute MDMA, at dose of 3 mg/kg, notably impaired copulatory behavior of sexually experienced male rats. In particular, MDMA-exposed animals exhibited a significant increase in intromission and ejaculation latencies as well as a significant decrease in percentage of rats displaying copulatory activity (one intromission at least). Surprisingly, one hour exposure to loud music, which per se resulted ineffective, antagonized the suppressive effect of MDMA by increasing the percent of animals displaying sexual activity. However, combined treatment of MDMA and music stimulation did not fully restore normal sexual behavior as the animals reaching ejaculation still showed a marked reduction of copulatory efficiency. These findings demonstrate that the systemic administration of a single low dose of MDMA, alone or in combination with loud music, which is commonly present in certain environments such as rave parties, notably impairs copulatory activity of male rats.

Neurofunctional effects in rats prenatally exposed to fluoxetine.

In the treatment of depression fluoxetine [a selective serotonine reuptake inhibitor (SSRIs)] is a widely used drug in humans. The selectivity, efficacy, side effects and simplicity of dosage contributed to fluoxetine's clinical acceptance. Several psychiatric disorders (many of them responsive to SSRIs) are present during pregnancy; up to 10% of pregnant women fulfill diagnostic criteria for major or minor depression with an even higher percentage developing postpartum depression. Therefore, significant numbers of women may be taking SSRIs while pregnant. Since fluoxetine's safe use during pregnancy is not yet established and experimental studies inconclusive, we performed the present research in order to investigate the neurobehavioral effects produced in rats by prenatal exposure to fluoxetine (5 and 10 mg/kg/sc from day 13 to 20 of gestation) on cognitive functions, emotional reactivity and sexual performance.

Psoriasis disappearance after the first phase of an oncologic treatment: a serendipity case report.

Psoriasis is a multifaceted disorder with psychosocial and physical aspects that negatively impact the quality of life. Strategies of treatment must address both rapid control of the disease and maintenance of benefits. For short and long-term control of localized psoriasis, recent data support the combined use of topical corticosteroids and either calcipotriene or tazarotene which seem to be the most effective approach. For generalized disease, UVB treatment provides the safest means of achieving long-term control of the disease. Acitretin is a very helpful adjunct for improving the efficacy of phototherapy. For patients with severe, refractory disease, methotrexate may be most effective while cyclosporine may be most valuable for patients needing rapid, short-term improvement. Other molecules, with different pharmacological properties, are actually under consideration. Herein it is reported a case of a 55 year old male, who refers, 2 weeks after the fi rst cycle of oncologic therapy with gemcitabine and cisplatin for a lung neoplasm, about the complete remission of the psoriasis on both fingernails and scalp, suffered since almost ten years. Three months after the fortuitous detection of the psoriasis disappearance, there is no further evidence of psoriatic lesions.

Neurofunctional effects of developmental sodium fluoride exposure in rats.

Contrasting studies on the toxic effects of sodium fluoride (NaF) during developmental stages of Wistar rats, lead us to investigate the neurofunctional effects caused by its perinatal exposure, devoid of any overt sign of toxicity and/or gross malformation. NaF solution was administered to pregnant rats by intragastric gavage at a daily dose of 2.5 and 5.0 mg/kg from gestational day 0 to day 9 after parturition. Developmental NaF exposure caused sex and dose specific behavioural deficits which affected males more than females in the majority of the evaluated end-points. In particular, the perinatal exposure to NaF 5.0 mg/kg, significantly affected learning, memory, motor coordination and blood pressure only in male rats. Conversely, a lack of habituation upon the second presentation of the objects and failure in the ability to discriminate between the novel and the familiar object were observed only in NaF 5.0 mg/kg female rats. Finally, a significant impairment of sexual behaviour was observed in male rats at both NaF dose levels. The present data indicate that perinatal rat exposure to NaF results in long lasting functional sex-specific alterations which occur at fluoride levels approaching those experienced by offspring of mothers.
