A 25-year-old schizophrenic man presented with abdominal pain, nausea, vomiting, weight loss and anaemia. He was noted to be malnourished with generalised muscle atrophy. Laboratory investigations showed Hb 4.7 mmol/L, MCV 80fl, bilirubin 75 micromol/L and reticulocyte count 93 percent. Peripheral blood films showed anisocytosis, basophilic stippling and Cabot's rings. Electromyography confirmed typical motor nerve neuropathy. The clinical and laboratory findings were that of lead poisoning. The patient was later found to be ingesting lead-containing paint. He was treated with lead-chelating agents.

The benefit of levodopa and carbidopa therapy in improving visual function in patients with non-arteritic anterior ischaemic neuropathy (NAION) was evaluated. Twenty-four subjects with NAION were randomly selected to receive either levodopa-carbidopa or a placebo. Visual functions of neither the study nor the placebo groups showed improvement. Side effects of levodopa such as dizziness, orthostatic hypotension, vomiting and cardiac arrhythmia were seen. Levodopa and carbidopa had no therapeutic effect on visual recovery in our patients with NAION.

The objective of this study was to provide preliminary toxicity data of multiple-cycle combination chemotherapy with intraperitoneal (IP) carboplatin and intravenous (IV) paclitaxel for further clinical trials. The toxicity data of 42 patients with mullerian carcinoma who underwent IP carboplatin therapy in combination with IV paclitaxel were retrospectively analyzed. Chemotherapy was repeated through the Bard IP port placed at initial surgery using IV paclitaxel at 175 mg/m2 followed by IP carboplatin. The doses of carboplatin were either at area under the curve (AUC) = 5, 6, 6.5, 7, or 7.5. The toxicity data in a total of 237 cycles were analyzed. The median number of cycles for IP chemotherapy was 6 (range: 3-12). The incidences of maximal grade toxicities in all cycles were: grade (G)2/3 nausea/vomiting, 23.8%; G2/3 constipation, 42.9%; G2 abdominal pain, 28.6%; G2/3 sensory neuropathy, 14.3%; motor neuropathy, 4.8%; myalgia/arthralgia 33.4%; G3/4 neutrocytopenia, 85.4%; and G3/4 anemia, 35.4%. These were not related to the dose of carboplatin. The incidences of G3 thrombocytopenia in relation to the dose of carboplatin were AUC = 5, 0%; 6, 31.6%; 6.5, 44.4%; 7, 25.0%; and 7.5, 80%. G4 thrombocytopenia did not occur. A dose of carboplatin between AUC = 6 and 7 with IV paclitaxel at 175 mg/m2 is warranted for further evaluation.

Oxaliplatin plus fluorouracil/folinic acid (5-FU/FA) every 2 weeks has shown promising activity in advanced gastric cancer. This study assessed the efficacy and safety of weekly oxaliplatin plus 5-FU/FA (FUFOX regimen) in the metastatic setting. Patients with previously untreated metastatic gastric cancer received oxaliplatin (50 mg m(-2)) plus FA (500 mg m(-2), 2-h infusion) followed by 5-FU (2000 mg m(-2), 24-h infusion) given on days 1, 8, 15 and 22 of a 5-week cycle. The primary end point of this multicentre phase II study was the response rate according to RECIST criteria. A total of 48 patients were enrolled. Median age was 62 years and all patients had metastatic disease, with a median number of three involved organs. The most common treatment-related grade 3/4 adverse events were diarrhoea (17%), deep vein thrombosis (15%), neutropenia (8%), nausea (6%), febrile neutropenia (4%), fatigue (4%), anaemia (4%), tumour bleeding (4%), emesis (2%), cardiac ischaemia (2%) and pneumonia (2%). Grade 1/2 sensory neuropathy occurred in 67% of patients but there were no episodes of grade 3 neuropathy. Intent-to-treat analysis showed a response rate of 54% (95% CI, 39-69%), including two complete responses. At a median follow-up of 18.1 months (range 11.2-26.2 months), median survival is 11.4 months (95% CI, 8.0-14.9 months) and the median time to progression is 6.5 months (95% CI, 3.9-9.2 months). The weekly FUFOX regimen is well tolerated and shows notable activity as first-line treatment in metastatic gastric cancer.

The authors describe an acute facial and acoustic neuropathy following gamma knife surgery (GKS) for vestibular schwannoma (VS). This 39-year-old woman presenting with tinnitus underwent GKS for a small right-sided intracanalicular VS, receiving a maximal dose of 26 Gy and a tumor margin dose of 13 Gy to the 50% isodose line. Thirty-six hours following treatment she presented with nausea, vomiting, vertigo, diminished hearing, and a House-Brackmann Grade III facial palsy. She was started on intravenous glucocorticosteroid agents, and over the course of 2 weeks her facial function returned to House-Brackmann Grade I. Unfortunately, her hearing loss persisted. A magnetic resonance (MR) image obtained at the time of initial deterioration demonstrated a significant decrease in tumor enhancement but no change in tumor size or peritumoral edema. Subsequently, the patient experienced severe hemifacial spasms, which persisted for a period of 3 weeks and then progressed to a House-Brackmann Grade V facial palsy. During the next 3 months, the patient was treated with steroids and in time her facial function and hearing returned to baseline levels. Results of MR imaging revealed transient enlargement (3 mm) of the tumor, which subsequently returned to its baseline size. This change corresponded to the tumor volume increase from 270 to 336 mm3. The patient remains radiologically and neurologically stable at 10 months posttreatment. This is the first detailed report of acute facial and vestibulocochlear neurotoxicity following GKS for VS that improved with time. In addition, MR imaging findings were indicative of early neurotoxic changes. A review of possible risk factors and explanations of causative mechanisms is provided.

Capecitabine plus oxaliplatin every 3 weeks (XELOX regimen) has proven efficacy in patients with colorectal carcinoma. We investigated this combination in patients with previously untreated advanced gastric carcinoma. The study population comprised patients with histologically confirmed nonresectable advanced gastric adenocarcinoma. Patients received intravenous oxaliplatin 130 mg m(-2) over 2 h on day 1 plus oral capecitabine 1000 mg m(-2) twice daily on days 1-14, every 3 weeks. Patients received a maximum of eight cycles. Twenty evaluable patients (17 men, 3 women) with a median age of 64 years (range 38-75) were enrolled. The overall response rate was 65% (95% confidence interval (CI), 44-86%), with complete responses in two patients and partial responses in 11 patients. Median progression-free survival was 7.5 months (95% CI, 3.2-11.7 months); median overall survival was not reached during the study period. There was no grade 4 and little grade 3 toxicity. The most common haematological adverse event was anaemia (65% of patients) and the most common nonhaematological toxicities were vomiting (65%), neuropathy (60%), diarrhoea (30%), and hand-foot syndrome (20%). In conclusion, XELOX is apparently as effective as triplet combinations and is well tolerated as first-line therapy for advanced gastric carcinoma. We are starting a large multi-institutional phase II study of XELOX in this setting.

The neuronal ceroid lipofuscinoses (NCLs) are inherited lysosomal storage diseases characterized by progressive neuropathy and the accumulation of autofluorescent cytoplasmic granules. Clinical signs of a new canine NCL began in a 9-month-old male Dachshund with vomiting, mental dullness, and loss of previously learned commands and rapidly progressed to include disorientation, ataxia, visual deficits, generalized myoclonic seizures, and death at 12 months of age. Neurons throughout the CNS contained autofluorescent storage granules that stained with periodic acid-Schiff and Luxol fast blue stains. Electron microscopy revealed that the storage granule contents consisted of curvilinear-appearing material characteristic of human late infantile NCL caused by CLN2 mutations. Nucleotide sequence analysis of canine TPP1, the ortholog of human CLN2, revealed a single nucleotide deletion in exon 4 which predicted a frame shift with a premature stop codon. Brain tissue from the affected dog lacked detectable activity of the tripeptidyl-peptidase enzyme encoded by TPP1, whereas the specific activities of 15 other lysosomal enzymes were higher than those in the brains of three control dogs. The affected Dachshund was homozygous for the mutant c.325delC allele, his sire and dam were heterozygotes, and 181 unrelated dogs, including 77 Dachshunds, were all homozygous for the wild-type allele. A DNA assay that detects the mutant allele will help Dachshund breeders avoid producing affected puppies in future generations. Furthermore, this Dachshund NCL may prove to be a useful model for studying the pathogenesis of neurodegeneration in human late infantile NCL and for evaluating novel therapeutic interventions for this disease.

The therapeutic efficacy and adverse reactions were compared between 14 patients who received TJ therapy using paclitaxel (PTX) and carboplatin (CBDCA) and 39 who received CAP therapy using cyclophosphamide (CPA), doxorubicin (DXR) and cisplatin (CDDP) as postoperative chemotherapy for cancer of the uterine body. In TJ therapy, PTX (175 mg/m(2)) and CBDCA (AUC 5) were administered on Day 1 (every 3 weeks), while in CAP therapy, CPA (500 mg/m(2)), DXR (40 mg/m(2)) and CDDP (50 mg/m(2)) were administered on Day 1 (every 4 weeks). Grade 3 or more severe hematotoxicity included leukocytopenia (incidence in the TJ and CAP groups: 71.4% and 64.1%, respectively), neutropenia (100%, 87.1%), thrombocytopenia (0%, 12.8%), and anemia (0%, 20.5%). No significant differences were noted between the two groups. Grade 3 or severe non-hematologic toxicities included nausea (0%, 15.4%) and vomiting (0%, 12.8%) with significantly higher incidence in the CAP therapy group (p=0.0000736, p=0.000736), peripheral sensory disturbance (7.1%, 0%) and arthralgia (7.1%, 0%) with significantly higher incidence in the TJ therapy group (p=0.00129, p=0.00000538). The survival rate and disease-free survival rate showed no significant differences between the two groups. TJ therapy is thought to be as effective as CAP therapy, and can be safely conducted, although precautions are required regarding arthralgia and neuropathy.

Experimental evidence indicates that chronic mechanical sub-occlusion of the intestine may damage the enteric nervous system (ENS), although data in humans are lacking. We here describe the first case of enteric degenerative neuropathy related to a congenital obstruction of the gut. A 3-year and 9-mo old girl began to complain of vomiting, abdominal distension, constipation with air-fluid levels at plane abdominal radiology. Her subsequent medical history was characterized by 3 operations: the first showed dilated duodeno-jejunal loops in the absence of occlusive lesions; the second (2 years later) was performed to obtain full-thickness biopsies of the dilated intestinal loops and revealed hyperganglionosis at histopathology; the third (9 years after the hyperganglionosis was identified) disclosed a Ladd's band which was removed and the associated gut malrotation was corrected. Repeated intraoperative full-thickness biopsies showed enteric degenerative neuropathy along with reduced interstitial cells of Cajal network in dilated loops above the obstruction and a normal neuromuscular layer below the Ladd's band. One year after the latest surgery the patient tolerated oral feeding and did well, suggesting that congenital (partial) mechanical obstruction of the small bowel in humans can evoke progressive adaptive changes of the ENS which are similar to those found in animal models of intestinal mechanical occlusion. Such ENS changes mimic neuronal abnormalities observed in intestinal pseudo-obstruction.

Oxaliplatin (OXA) and irinotecan (IRI) are active drugs for metastatic colorectal cancer, their toxicity profiles are not overlapping, and both drugs have shown at least additivity with folinic acid-modulated 5-fluorouracil (5FU). We carried out this phase II study to assess the activity and toxicity of a biweekly regimen including OXA plus IRI on day 1, and levo-folinic acid (LFA) plus 5FU on day 2 (OXIRIFAFU) in pretreated patients with metastatic colorectal cancer. Forty-one patients, all previously treated with adjuvant and/or palliative 5FU-based chemotherapy (16 of them already exposed to IRI, OXA or both), were enrolled into this trial. On the basis of sensitivity to previous treatment, 19 patients were considered as chemo-resistant and 14 patients as chemo-refractory. OXA 110 mg/m (over 2 h) and IRI 175 mg/m (over 1 h) were delivered on day 1, followed by LFA 250 mg/m (2-h infusion) plus 5FU 800 mg/m as intravenous bolus on day 2. Cycles were repeated every 2 weeks. A total of 348 cycles were delivered, with a median of nine cycles per patient (range, 1-12 cycles per patient). Five complete and 13 partial responses were reported on 40 assessable patients, giving a response rate of 45% [95% confidence interval (CI), 29-62%]; eight of 19 (42%) resistant patients and five of 14 (36%) refractory patients achieved a major response, which was also obtained in four of eight (50%) patients pretreated with IRI and in three of eight (38%) patients pretreated with OXA. Grade 3 or higher neutropenia occurred in 68% of patients, but febrile neutropenia or infections affected only seven (17%) patients. No episodes of grade 3 or higher thrombocytopenia or anemia were recorded. Occurrence of severe non-hematologic toxicities by patients were: diarrhea, 34%; vomiting, 17%; peripheral cumulative neuropathy, 15%; stomatitis, 10%; acute cholinergic syndrome, 7%. Actually delivered dose intensities of all three drugs resulted in about two-thirds of the planned ones. After a follow-up of 39 months, median progression-free survival was 7.5 months. Median overall survival was 14.4 (95% CI, 10.4-18.4) months from the start of OXIRIFAFU and 25.3 (95% CI, 18.1-32.5) months from the diagnosis of metastatic disease. This OXIRIFAFU triplet regimen was highly effective in resistant/refractory colorectal cancer patients. A slight dose reduction of all cytotoxic drugs could be advisable in order to improve the tolerability of this regimen without jeopardizing its activity.
