The clinical suitability of conventional glyceromonooctanoin (GMOC) and ethylenediaminetetraacetic acid (EDTA) containing solvents for the dissolution of common bile duct stones is questionable. To improve the solvent-stone contact and the miscibility with bile, GMOC was hydrophilized by the addition of polyethyleneglycol-caprylglyceride, polyethyleneglycol-sorbitan-etheroleyl-ester, and polyethyleneglycol-sorbitanlauryl-ester (PEG-GMOC). This product was mixed with a bile acid-EDTA (BA-EDTA) solution in a ratio of 1:2 (v/v) for cholesterol solubilizing and calcium complexing capacities. To determine clinical efficiency, the new solvent was infused via a nasobiliary tube in 16 patients with endoscopically nonextractable common bile duct stones and compared with a group of 16 patients treated with an alternating GMOC/BA-EDTA regimen. Continuous perfusion with PEG-GMOC-BA-EDTA led to a total (12 patients) or partial (3 patients) disappearance of the stones within 2-15 days. Similarly, alternating GMOC and BA-EDTA treatment dissolved the stones in 12 patients. The average volume of PEG-GMOC-BA-EDTA infused contained only 27% of the GMOC applied during the alternating therapeutic regime. This reduction of the GMOC dose was associated with a significant reduction of adverse effects such as emesis, diarrhea and biliary pain. We concluded that GMOC is equally efficient in the new hydrophilized form but it is clearly superior as far as side effects are concerned. In all, this supports its clinical suitability for the dissolution treatment of common bile duct stones.

A 16-year-old boy ingested approximately 50 zinc sulfate tablets (ZnSO4; 500-mg tablets). After spontaneous emesis, ipecac-induced emesis, and orogastric lavage, an abdominal radiograph performed four hours after ingestion still demonstrated approximately 50 ZnSO4 tablets within the stomach and three pills within the colon. Whole-bowel irrigation was begun with a polyethylene glycol lavage solution (PEG; Golytely) that was administered through a nasogastric tube; within one hour, the patient began producing a rectal effluent that contained pills. The patient remained asymptomatic throughout whole-bowel irrigation. Stool guaiac tests were negative. The serum chloride, however, increased from 105 to 127 mEq/L. Follow-up kidney, ureter, and bladder studies demonstrated the clearance of the zinc tablets from the gastrointestinal tract during the next 24 hours.

42 dogs with non-Hodgkin's lymphoma (NHL) were randomized for treatment with either PEG-L-asparaginase 10 IU/kg intramuscularly (n = 22) or L-asparaginase 400 IU/kg intraperitoneally (n = 20). Another 20 dogs were treated with either PEG-L-asparaginase 30 IU/kg (n = 10) or L-asparaginase 400 IU/kg (n = 10). Each treatment protocol consisted of two asparaginase treatments followed by a 10-week period of induction chemotherapy and then maintenance on asparaginase until progression occurred. No significant differences were found between treatments in the response rates after 2 weeks of asparaginase therapy or in the time to relapse, the time to treatment failure or the remission period. The reaction to asparaginase after the initial 2 weeks was a prognostic factor for the total duration of remission under asparaginase maintenance therapy. No side-effects were noted in the dogs treated with PEG-L-asparaginase, whereas 14 (48%) of the L-asparaginase treated dogs had side-effects related to this drug, including anaphylactic shock (9), anorexia or vomiting (4), hypersensitivity-related oedema (3), seizures (1) and acute pancreatitis (1). No abnormalities in clotting times, fibrinogen levels or antithrombin-III levels were found in any of the 62 dogs. PEG-L-asparaginase has the same anti-tumour activity as native L-asparaginase in dogs with NHL, but lacks side-effects.

A new sulfate-free polyethylene glycol electrolyte lavage solution (SF-ELS) for colonoscopy was formulated to taste better and have less net water and electrolyte secretion and absorption than a standard polyethylene glycolelectrolyte lavage solution (PEG-ELS). At two centers, 157 patients were prospectively randomized to receive SF-ELS or PEG-ELS to assess adequacy of preparation, patient tolerance, weight changes, and various hematologic and biochemical parameters. Physician assessment of colon cleansing showed no difference between those patients receiving SF-ELS (N = 74) or PEG-ELS (N = 78). Eighty-two percent of all preps were found to be "clinically acceptable." Subjects receiving SF-ELS had significantly less fullness and cramps, while PEG-ELS subjects reported less nausea. There was no difference between groups for vomiting, overall discomfort, or willingness to repeat the preparation received. Eighty percent of all patients would repeat the randomized cleansing methods. There were no clinically significant changes in weight or assessed laboratory parameters, with the exception of potassium where PEG-ELS patients had an mean decrease of 0.22 mEq/liter vs. 0.01 mEq/liter for SF-ELS (p less than or equal to 0.01). Patient taste questionnaires in those patients expressing a preference showed a preference for SF-ELS (76.6%) over PEG-ELS (23.4%) (p less than or equal to 0.001). Thirty-two (22.5%) of total respondents indicated no preference. We conclude that SF-ELS when compared with PEG-ELS is similarly a safe and effective method of colon cleansing for colonoscopy that is well tolerated. Patients prefer the taste of the new solution.

The use of polyethylene glycol electrolyte lavage solution (PEG-ELS) as a whole-bowel irrigation for colorectal surgery is retrospectively evaluated in 65 consecutive patients. Sixty-three (97%) of the patients were able to complete the lavage. Fifty-five (85%) of these tolerated the preparation without event. Unpleasant reactions of nausea, vomiting, or fullness resolved in most patients by decreasing the rate of ingestion. Twenty-seven patients had associated medical illnesses that may have been aggravated by volume overload, but none of these experienced any adverse effects from the lavage. Most patients completed the total lavage ingestion of 4 L in 4 hours, which resulted in a 1-day preparation prior to operation. There were no wound or septic complications in any of the lavage patients. This clinical review indicates that PEG-ELS is a safe, rapid, and effective mechanical bowel preparation that should be able to reduce in-hospital preparation time for most patients undergoing colorectal surgery.

Spontaneous ventriculocisternostomy rarely occurs in obstructive hydrocephalus. The authors experienced a case of spontaneous ventriculocisternostomy diagnosed by CT scan with metrizamide and Conray. Patient was 23-year-old male who had been in good health until one month before admission, when he began to have headache and tinnitus. He noticed bilateral visual acuity was decreased about one week before admission and vomiting appeared two days before admission. He was admitted to our hospital because of bilateral papilledema and remarkable hydrocephalus diagnosed by CT scan. On admission, no abnormal neurological signs except for bilateral papilledema were noted. Immediately, right ventricular drainage was performed. Pressure of the ventricle was over 300 mmH2O and CSF was clear. PVG and PEG disclosed an another cavity behind the third ventricle, which was communicated with the third ventricle, and occlusion of aqueduct of Sylvius. Metrizamide CT scan and Conray CT scan showed a communication between this cavity and quadrigeminal and supracerebellar cisterns. On these neuroradiological findings, the diagnosis of obstructive hydrocephalus due to benign aqueduct stenosis accompanied with spontaneous ventriculocisternostomy was obtained. Spontaneous ventriculocisternostomy was noticed to produce arrest of hydrocephalus, but with our case, spontaneous regression of such symptoms did not appeared. In the literature, arrest of hydrocephalus was noted in 50 per cent of 14 cases of obstructive hydrocephalus with spontaneous ventriculocisternostomy. By surgical ventriculocisternostomy (method by Torkildsen, Dandy, or Scarff), arrest of hydrocephalus was seen in about 50 to 70 per cent, which was the same results as those of spontaneous ventriculocisternostomy. It is concluded that VP shunt or VA shunt is thought to be better treatment of obstructive hydrocephalus than the various kinds of surgical ventriculocisternostomy.

In a prospective cohort study, which was carried out at the department for abdominal surgery of the university of Mainz from June to December 1993, two methods of bowel preparation for elective colorectal surgery were compared: oral bowel preparation with Fordtran a new polyethylene glycol solution (63 patients), and whole-gut lavage with Ringer's solution (37 patients). The serum chloride levels and the bodyweight increased significantly more in the whole-gut lavage group. These patients also showed a higher frequency of vomiting during bowel preparation. Neither the bowel cleansing effect nor the postoperative complications differed significantly between the two groups. Owing to these results, the better patient acceptance, and the easier handling and lower costs of PEG solution, we recommend this method of preoperative bowel preparation for elective colorectal surgery.

Carboxyamido-triazole (CAI) is a synthetic inhibitor of non-excitable calcium channels that reversibly inhibits angiogenesis, tumor cell proliferation, and metastatic potential. Inhibition of calcium influx and calcium-dependent events is a potential common mechanism underlying these effects of CAI. The cytostatic and antiangiogenic properties of CAI led to its development for clinical investigation. In a Phase I clinical trial open to patients with refractory solid tumors, 49 patients received p.o. administered CAI daily or every other day. Two oral formulations, PEG-400 CAI solution and a gelatin capsule containing CAI in PEG-400, were tested. All administered dosages of CAI yielded plasma concentration at or above the range demonstrated to be effective in inhibiting signaling and cancer progression in vitro and in preclinical models (1 microgram/ml, 2.3 microM). Toxicity of p.o. administered CAI most commonly consisted of dose-related grade 1-2 nausea, vomiting, and occasional anorexia. CAI administration at bedtime ameliorated gastrointestinal complaints in many patients; others required addition of simple antiemetic regimens, usually consisting of metoclopropamide or prochlorperazine. Gastrointestinal complaints were the cause for compliance-limiting toxicity at 175 mg/m2/day of the liquid formulation and 125 mg/m2/day of the gelatin capsule formation. Reversible and rare sensory axonal neuropathy (grade 3, 1 patient) and neutropenia (grade 4, 1 patient) were dose-limiting toxicities observed at the 330 mg/m2 every-other-day liquid CAI dose level. No evidence of cumulative end organ damage or central nervous system injury was observed. Disease stabilization and improvement in performance status was observed. Disease stabilization and improvement in performance status was observed in 49% of evaluable patients who had disease progression before CAI. Disease stabilization and associated improvement in performance status was seen in patients with renal cell carcinoma (7 months), pancreaticobiliary carcinomas (3, 5, and 5 months), melanoma (7 months), ovarian cancer (7 months), and non-small cell lung cancer (3 months). The recommended Phase II doses from this trial are 150 mg/m2/day in the liquid formation and 100 mg/m2/day in the gelatin capsule formation.

Double-contrast enema is often unsuccessful in elderly patients because of their poor cooperation and colon cleaning. This work was aimed at showing that a well-done single-contrast exam with simple colon lavage can make a very good alternative to double-contrast enema in elderly patients. Thus, 66 consecutive elderly patients (age range: 70-90 years) were submitted, over a 6-month period (June-December, 1994), to single-contrast enema, after colon cleaning with oral whole-gut lavage, using an osmotically balanced electrolyte solution (Isocolan, Bracco) containing polyethylenglycol (PEG 4000). We examined, in each patient: a) the tolerance to and effectiveness of bowel cleaning, according to the liquid volume drunk by each subject, needed to obtain clear diarrhea; b) radiograph quality. Successful colon cleaning was achieved with a mean (2.5-3 liters) and a large (3.5-4 liters) amount of solution, in 80% and 20% of our patients, respectively. Tolerance was good in the whole series except for 3 patients with emesis. Moreover, radiograph quality was good in 85% of the subjects. Finally, barium enema results, compared with endoscopic results, yielded 27 true positives, 3 false negatives (small neoplastic lesions) and 1 false positive. Therefore, in our opinion, these results confirm the role of single-contrast enema, combined with gut lavage, in elderly patients.

L-asparaginase is widely used in the treatment of acute lymphoblastic leukemia in children and adults. Use of L-aspa E. Coli as well as Erwinase is not possible in all cases because of the side effects, mainly allergic reactions and disfunction of pancreas. Recently, the new form of the enzyme PEG-L-asparaginase was introduced. Binding L-asparaginase E. coli to polyethylene glycol a decreased its toxicity, extended its plasma half-live, not significantly affecting the efficacy. The aim of the study was to examine the results of PEG-L-asparaginase administration in five children with acute lymphoblastic leukemia, and the symptoms of intolerance to L-aspa E. Coli or Erwinase. There were three children with newly diagnosed ALL and two children with first relapse of ALL, treated according to New York Protocol and BFM-90 Protocol for ALL relapses respectively. PEG-L-asparaginase (Oncaspar) was administered in the dose of 2500 IU/m2. According to the protocol four children received 11 courses of treatment with the full dose of the drug. The number of doses for individual patient varied from one to six. The short-lived nettlerash was observed in one patient during two subsequent infusions of the drug. Hydrocortisone and antihistamine drugs were administered. Treatment with PEG-asparaginase was discontinued in one child, who developed dyspnea, nausea, vomiting and face rash during the third dose of the drug. Oncaspar is the valuable drug, which enabled continuation of treatment according to protocol in four out of five children with bad tolerance to routinely used L-asparaginase preparations.
