The extragonadal germ cell tumor are uncommon neoplasms which account for only 1-5% of germ cell tumors, and its prognosis is poor. We report here the use of combination chemotherapy with cisplatin, etoposide, bleomycin, and vinblastine (PVeBV) for the treatment of retroperitoneal germ cell tumor. A 28-year-old male with complaints of abdominal pain and lumbago, without any abnormality in both testes by physical and ultrasonographic examination, showed retroperitoneal tumor by abdominal computed tomography. The serum alpha-fetoprotein and lactate dehydrogenase were elevated. The retroperitoneal tumor was treated surgically. The pathological diagnosis was mixed germ cell tumor. The lung and supraclavicular lymph node metastases disappeared completely after 3 courses of PVeBV chemotherapy with cisplatin (40 mg/m2 per day) and etoposide (100 mg/m2 per day) for 5 consecutive days, with vinblastine (0.2 mg/kg) on day 1, and bleomycin (30 mg/body) given on days 1, 8, and 15. Granulocyte colony-stimulating factor and serotonin receptor antagonist application were available on acute phase toxic effects. The patient is now alive and well, without recurrence, more than 26 months after the operation.

Tegaserod is a medication that has been shown to be of benefit in women with irritable bowel syndrome (IBS) associated with abdominal pain, bloating, and constipation. Tegaserod is a selective serotonin receptor subtype 4 partial agonist designed to interact with the network of cells and nerves throughout the gastrointestinal tract that use serotonin. Tegaserod has been shown to modulate both gastrointestinal motility and visceral sensitivity. Specifically, it increases the peristaltic reflex and decreases visceral sensitivity. Clinical studies have shown that tegaserod improves symptoms of abdominal pain, bloating, and constipation in women with IBS. This article discusses the role of serotonin in gastrointestinal tract physiology, the structure and pharmacokinetic profile of tegaserod, and clinical applications of this new drug.

Irritable bowel syndrome (IBS) is a common functional bowel disorder of unknown aetiology. It is defined by the presence of gastrointestinal (GI) symptoms including abdominal pain/discomfort, bloating and bowel motor dysfunction. No available therapy is yet effective against all the symptoms of the disorder. Current treatments therefore target individual symptoms but may be accompanied by unpleasant side-effects. Tegaserod is a novel selective serotonin receptor type-4 (5-HT4) partial agonist with structural similarity to 5-HT Tegaserod stimulates small bowel and colonic motility and helps to normalise GI function. Clinical trials using a patient's assessment of efficacy demonstrate that tegaserod significantly improves key symptoms of IBS: abdominal pain/discomfort, bloating and constipation. Tegaserod is well tolerated with an excellent safety profile and represents a significant treatment advance in this difficult-to-treat disorder.

Irritable bowel syndrome (IBS) is a highly prevalent functional gastrointestinal disorder affecting up to 3-15% of the general population in Western countries. It is characterised by unexplained abdominal pain, discomfort and bloating in association with altered bowel habits. The pathophysiology of IBS is considered to be multifactorial, involving disturbances of the brain-gut-axis: IBS has been associated with abnormal gastrointestinal motor functions, visceral hypersensitivity, psychosocial factors, autonomic dysfunction and mucosal inflammation. Traditional IBS therapy is mainly symptom oriented and often unsatisfactory. Hence, there is a need for new treatment strategies. Increasing knowledge of brain-gut physiology, mechanisms, and neurotransmitters and receptors involved in gastrointestinal motor and sensory function have led to the development of several new therapeutic approaches. This article provides a systematic overview of recently approved or novel medications that show promise for the treatment of IBS; classification is based on the physiological systems targeted by the medication. The article includes agents acting on the serotonin receptor or serotonin transporter system, novel selective anticholinergics, alpha-adrenergic agonists, opioid agents, cholecystokinin antagonists, neurokinin antagonists, somatostatin receptor agonists, neurotrophin-3, corticotropin releasing factor antagonists, chloride channel activators, guanylate cyclase-c agonists, melatonin and atypical benzodiazepines. Finally, the role of probiotics and antibacterials in the treatment of IBS is summarised.

Irritable bowel syndrome (IBS) is a chronic, relapsing disease characterised by abdominal pain and altered bowel movements. This review assesses the clinical trials of the partial serotonin receptor agonist tegaserod in women with constipation type IBS. Significantly more women treated with tegaserod obtained sufficient relief from symptoms during at least 2 out of 4 weeks, but the absolute therapeutic gain of approximately 10 percent was not deemed clinically relevant. Two marketing authorisation applications in the European Union have been rejected due to the minor therapeutic gain. Tegaserod was removed from the market in the USA in March 2007 due to an increased risk of severe cardiovascular adverse events.

Irritable bowel syndrome is a functional gastrointestinal disorder affecting up to 3-15% of the general population in western countries. It is characterised by unexplained abdominal pain, discomfort, and bloating in association with altered bowel habits. The pathophysiology of irritable bowel syndrome is multifactorial involving disturbances of the brain-gut axis. The pathophysiology provides the rationale for pharmacotherapy: abnormal gastrointestinal motor functions, visceral hypersensitivity, psychosocial factors, autonomic dysfunction, and mucosal immune activation. Understanding the mechanisms, and their mediators or modulators including neurotransmitters and receptors have led to several therapeutic approaches including agents acting on the serotonin receptor or serotonin transporter system, antidepressants, novel selective anticholinergics, alpha-adrenergic agonists, opioid agents, cholecystokinin-antagonists, neurokinin-antagonists, somatostatin receptor agonists, corticotropin releasing factor antagonists, chloride channel activators, guanylate cyclase-c agonists, melatonin, atypical benzodiazepines, antibiotics, immune modulators and probiotics. The mechanisms and current evidence regarding efficacy of these agents are reviewed.
