We describe a 60-year-old male patient with acute intermittent porphyria (AIP) who presented with initial abdominal pain and subsequent quadriplegia and respiratory failure. Small fiber neuropathy was demonstrated by measuring intra-epidermal nerve fiber density (IENFD) using protein gene product 9.5 (PGP 9.5) immunostaining on three consecutive skin punch biopsies of the distal lower limb. The biopsy findings demonstrated some correlation with progression of the patient's clinical condition. Neuropathy in AIP can have a small-fiber component rather than being solely a large-fiber neuropathy.

Intestinal pseudo-obstruction is a rare motility disorder with symptoms and clinical signs of bowel obstruction without a mechanical cause. Symptoms might be acute or chronic. The pathogenesis of acute colonic pseudo-obstruction (Ogilvie's syndrome) is likely to result from an imbalance of the autonomic regulation of the colon. Chronic intestinal pseudo-obstruction (CIPO) may be congenital or acquired. A variety of underlying pathologies, e.g. visceral neuropathy or visceral myopathy are known. Main symptoms are abdominal pain, vomiting, constipation or diarrhoea. Mechanical obstruction, ischemia and perforation should be excluded. Supportive therapy, medical therapy or an intervention (endoscopy, surgery) might be necessary in Ogilvie's syndrome depending on ceacal diameter and duration of distension. Treatment of CIPO depends on the severity of the disease and often needs a multidisciplinary approach.

A 68-year-old woman underwent right colectomy for cancer of the ascending colon, followed by a local recurrence 26 months after surgery. She presented with fever and right lower abdominal pain, and was admitted to the hospital for locally recurrent colorectal cancer and tumor rupture. The patient was treated with a modified (reduced-dose) FOLFOX 4 regimen (mFOLFOX 4). In the four course of this regimen, the serum level of CEA decreased from 268 to 2.3 ng/mL. Even after 8 course, the serum CEA level remained within the normal range (4.7 ng/mL). Our case suggests that the mFOLFOX 4 regimen is effective for advanced or recurrent colorectal cancer with less toxicities including neuropathy,thus enabling patients to undergo long-term therapy.

There are several surgical complications which can occur following simultaneous pancreas-kidney transplantation (SPKT). Although intestinal obstruction is known to be a common complication after any type of abdominal surgery, the occurrence of small bowel volvulus, which is one of the rare causes of intestinal obstruction, following SPKT has not been published before. A 24-year-old woman suffering from type I diabetes mellitus with complications of nephropathy resulting in end stage renal disease (ESRD), neuropathy and retinopathy underwent SPKT. On the postoperative month 5, she was brought to the emergency service due to abdominal distention with mild abdominal pain. After laboratory research and diagnostic radiological tests had been carried out, she underwent exploratory laparotomy to determine the pathology for acute abdominal symptoms. Intra-operative observation revealed the presence of an almost totally ischemic small bowel which had occurred due to clockwise rotation of the mesentery. Initially, simple derotation was performed to avoid intestinal resection because of her risky condition, particularly for short bowel syndrome, and subsequent intestinal response was favorable. Thus, surgical treatment was successfully employed to solve the problem without any resection procedure. The patient's postoperative follow-up was uneventful and she was discharged from hospital on postoperative day 7. According to our clinical viewpoint, this study emphasizes that if there is even just a suspicion of acute abdominal problem in a patient with SPKT, surgical intervention should be promptly performed to avoid any irreversible result and to achieve a positive outcome.

Diabetes is associated with several changes in gastrointestinal (GI) motility and associated symptoms such as nausea, bloating, abdominal pain, diarrhoea and constipation. The pathogenesis of altered GI functions in diabetes is multifactorial and the role of the enteric nervous system (ENS) in this respect has gained significant importance. In this review, we summarize the research carried out on diabetes-related changes in the ENS. Changes in the inhibitory and excitatory enteric neurons are described highlighting the role of loss of inhibitory neurons in early diabetic enteric neuropathy. The functional consequences of these neuronal changes result in altered gastric emptying, diarrhoea or constipation. Diabetes can also affect GI motility through changes in intestinal smooth muscle or alterations in extrinsic neuronal control. Hyperglycaemia and oxidative stress play an important role in the pathophysiology of these ENS changes. Antioxidants to prevent or treat diabetic GI motility problems have therapeutic potential. Recent research on the nerve-immune interactions demonstrates inflammation-associated neurodegeneration which can lead to motility related problems in diabetes.

Neurologic disorders represent the most severe complications of acute intermittent porphyria (AIP). Cognitive disturbances, bulbar and spinal weakness appear as the most critical neurological complications as they may lead to death or definitive motor weakness. A 38-year-old woman was admitted for an acute and painful tetra paresis occurring after a laparoscopy for an ovarian cyst. She also complained of abdominal pain treated with noramidopyrine, tachycardia, hypertension and hyponatremia. The electrophysiological examination showed a motor axonal neuropathy. The increase of Urine ALA at 268 micromol/l (N<38) and of at 235 micromol/l (N<5) strongly suggested AIP that was further confirmed by PBG desaminase deficiency in red cells. Thanks to the prescription of heme arginate (HA) at the dose of 3 mg/kg/day for 4 days, pain resolved immediately and motor function began to improve since the second day of treatment concurrently to a dramatic decrease of both urine ALA and PBG concentrations. Motor recovery was complete after 12 months of evolution. This case illustrates the potential severity of acute porphyric neuropathy when precipitating factors (noramidopyrine, surgery) are present in previously undiagnosed AIP. Moreover, motor neuronal function improved while HA therapy was initiated 22 days after the clinical onset of weakness. This tempts us to propose HA therapy at any stage of acute porphyric neuropathy.

Within an ongoing multicentre phase 3 randomised trial (ELDA, cancertrials.gov ID: NCT00331097), early breast cancer patients, 65-79 years old, with average to high risk of recurrence, are randomly assigned to receive CMF (cyclophosphamide 600 mg/m2, methotrexate 40 mg/m2, fluorouracil 600 mg/m2, days 1-8) or docetaxel (35 mg/m2 days 1-8-15), every 4 weeks. Here we report an unplanned safety analysis prompted by an amendment introducing creatinine clearance as a tool to adjust methotrexate dose. Before such change, 101 patients with a median age of 70 were randomly assigned CMF (53 patients) or docetaxel (48 patients). At least one grades 3-4 toxic event of any type was reported in 40 (75.5%) and 19 (39.6%) patients with CMF and docetaxel, respectively (p=0.0002). Grades 3-4 hematological events were observed in 37 (69.8%) vs. 4 (8.3%) cases (p<0.0001) and grades 3-4 non-hematological toxicity in 12 (22.6%) vs. 15 (31.2%) patients (p=0.11), with CMF and docetaxel, respectively. A higher incidence of anemia, neutropenia, thrombocytopenia and febrile neutropenia was reported with CMF. Constipation, mucositis, nausea and vomiting were more common with CMF; diarrhoea, abdominal pain, dysgeusia, neuropathy and liver toxicity were more frequent with docetaxel. No significant interaction was found between the occurrence of severe toxicity and baseline variables, including creatinine clearance and geriatric activity scales. In conclusion, weekly docetaxel appears to be less toxic than CMF in terms of hematological toxicity.

Abdominal pain is an important clinical symptom in pancreatic diseases. There is increasing evidence that pain in chronic pancreatitis and pancreatic cancer is triggered by pancreatic neuropathy. Damage to intrapancreatic nerves seems to support the maintenance and exacerbation of neuropathic pain. In chronic pancreatitis, intrapancreatic nerves are invaded by immune cells. This observation led to the hypothesis that neuro-immune interactions play a role in the pathogenesis of chronic pancreatitis and the accompanying abdominal pain syndrome. Similarly, pancreatic cancer cells infiltrate the perineurium of local nerves, which may in part explain the severe pain experienced by the patients. Furthermore, perineural invasion extending into extrapancreatic nerves may preclude curative resection and thus often leads to local recurrence. In recent years, the involvement of a variety of neurotrophins and neuropeptides in the pathogenesis of pancreatic pain was discovered. This review summarises recent data on the mechanisms of neuropathy and pain generation in pancreatic disorders.

Methyl bromide is a highly toxic gas with poor olfactory warning properties. It is widely used as insecticidal fumigant for dry foodstuffs and can be toxic to central and peripheral nervous systems. Most neurological manifestations of methyl bromide intoxication occur from inhalation. Acute toxicity characterized by headache, dizziness, abdominal pain, nausea, vomiting and visual disturbances. Tremor, convulsion, unconsciousness and permanent brain damage may occur in severe poisoning. Chronic exposure can cause neuropathy, pyramidal and cerebellar dysfunction, as well as neuropsychiatric disturbances. The first case of methyl bromide intoxication in Thailand has been described. The patient was a 24-year-old man who worked in a warehouse of imported vegetables fumigated with methyl bromide. He presented with unstable gait, vertigo and paresthesia of both feet, for two weeks. He had a history of chronic exposure to methyl bromide for three years. His fourteen co-workers also developed the same symptoms but less in severity. Neurological examination revealed ataxic gait, decreased pain and vibratory sense on both feet, impaired cerebellar signs and hyperactive reflex in all extremities. The serum concentration of methyl bromide was 8.18 mg/dl. Electrophysilogical study was normal. Magnetic resonance imaging of the brain (MRI) revealed bilateral symmetrical lesion of abnormal hypersignal intensity on T2 and fluid-attenuation inversion recovery (FLAIR) sequences at bilateral dentate nuclei of cerebellum and periventricular area of the fourth ventricle. This incident stresses the need for improvement of worker education and safety precautions during all stages of methyl bromide fumigation.

A 62-year-old woman complained of thin feces, lower blood and abdominal pain, and she was diagnosed as having bowel obstruction due to sigmoid colon cancer. Abdominal CT showed peritoneal dissemination and ascites on the surface of liver. The serum CEA levels were 663.7 ng/mL. We established a diagnosis of unresectable sigmoid colon cancer accompanied by severe peritoneal dissemination and therefore performed only transverse colostomy in April, 2006. Pathological examination of omental dissemination demonstrated moderately-differentiated adenocarcinoma. FOLFOX4 therapy was started on April, 2006. Primary lesion decrease and release from bowel obstruction after 4 cycles was judged as a partial response. The partial response continued, and the serum CEA decreased 18.5 ng/mL after completion of 16 cycles, but grade 3 neuropathy occurred. We started S-1 as second-line chemotherapy in May, 2007. There was primary lesion re-growth after 4 cycles, so we changed to S-1+CPT-11 therapy. The adverse events were grade 3 neuropathy and leucopenia throughout the course. Chemotherapy is now continued on an outpatient basis, 24 months after the medical treatment started. FOLFOX4 therapy is useful for patients with advanced colon cancer accompanied by peritoneal dissemination.
