AIM:To investigate predilection sites of recurrence of pancreatic cancer by computed tomography(CT)in follow-up after surgery. METHODS:Seventy seven patients with recurrence after pancreatic cancer surgery were retrospectively *** operative technique,R-status,T-stage and development of tumor markers were evaluated. Two radiologists analyzed CT scans with consensus *** of local recurrence,lymph node recurrence and organ metastases were *** and progression of findings on follow-up CT were con-sidered as reference standard. RESULTS:The mean follow-up interval was 3.9± 1.8 mo,with a mean relapse-free interval of 12.9± 10.4 *** predominant site of recurrence was local (65%),followed by lymph node(17%),liver metastasis (11%)and peritoneal carcinosis(7%).Local recurrence emerged at the superior mesenteric artery(n=28),the hepatic artery(n=8),in an area defined by the surrounding vessels:celiac trunk,portal vein,inferior vena cava(n=22),and in a space limited by the mesenteric artery,portal vein and inferior vena cava(n=17). Lymph node recurrence occurred in the mesenteric root and left lateral to the *** was confirmed by surgery(n=22)and follow-up CT(n=55).Tumor markers[carbohydrate antigen 19-9(CA19-9),carcinoembryonic antigen(CEA)]increased in accordance with signs of recurrence in most cases(86%CA19-9;79.2% CEA). COnCLUSIOn:Specific changes of local and lymph node recurrence can be found in the course of the cardinal peripancreatic *** superior mesenteric artery is the leading structure for recurrence.

Mirodenafil is a 5-phosphodiesterase inhibitor that is currently marketed in Korea for the treatment of erectile dysfunction;however, no information in other populations is available. It has been described that Mirodenafil is metabolized by CYP3A4, a metabolic pathway in which interethnic differences have been reported. The purpose of this study was to characterize the oral pharmacokinetics of Mirodenafil in Mexicans. Seventeen male healthy volunteers were enrolled in this study. After an overnight fast, volunteers received an oral 100 mg dose and blood samples were collected at selected times during 24 h. Plasma was stored frozen and analyzed by an HPLC method. Pharmacokinetic parameters obtained were: Cmax 331.129 ± 32.689 ng/mL, tmax 1.574 ± 0.293 h, AUC24h 883.293 ± 104.088 ng·h/mL, AUC￥ 976.477 ± 108.812 ng·h/mL and t1/2 1.807 ± 0.171 h. Parameter values observed in this study are similar to those reported in Koreans. Since efficacy and safety studies of Mirodenafil have been conducted in Koreans, it is expected that dosage regime to employ in Mexicans should be similar to the approved for Korean population.

Evaluation of the Influence of Hyoscine Butylbromide on the Oral Bioavailability of Lansoprazole in Healthy Adult Volunteers

Mexico City Mexico Unidad de Investigación en Farmacología Instituto Nacional de Enfermedades Respiratorias Ismael Cosío Villegas Mexico City Mexico Departamento de Biología Celular Instituto Nacional de Perinatología Isidro Espinosa de los Reyes Mexico City Mexico Sección de Estudios de Posgrado e Investigación Escuela Superior de Medicina Instituto Politécnico Nacional Mexico City Mexico

The gastroesophageal reflux and/or peptic ulcer diseases are clinical conditions that occur usually accompanied of symptomatic pain. Lansoprazole, a proton pump inhibitor class drug is widely used in clinical practice for treatment of these diseases. However, its efficacy can be improved by combining with spasmolytic and/or visceral analgesic such as hyoscine butylbromide. Since hyoscine butylbromide is barely absorbed and exerts some local effects at gastrointestinal tract which may modify the absorption of lansoprazole, it is important to establish if there is a pharmacokinetic interaction after the oral concomitant administration of both drugs. For this objective, twenty-five subjects received under a crossover design an oral administration of lansoprazole (15 mg) plus placebo or a fixed-dose combination with hyoscine butiylbromide (15 mg + 10 mg, respectively). Plasma samples were obtained at different times during 10 hours. Lansoprazole plasma concentrations were determined by a high performance liquid chromatography method coupled to tandem mass spectrometry. Fixed-dose combination was well tolerated. Lansoprazole pharmacokinetic parameters were: Cmax 621.81 ± 212.79 and 450.38 ± 192.14 ng/mL;AUC0-t 1941.36 ± 845.57 and 1454.66 ± 757.28 ng·h/mL;tmax 2.83 ± 0.99 and 3.40 ± 1.82h;t1/2 1.35 ± 0.39 and 1.45 ± 0.51 h, for alone and combined fixed-dose formulation, respectively. Pharmacokinetic parameters were compared by analysis of variance and ratios of AUC0-t, Cmax and 90% confidence intervals obtained. Since confidence intervals exceed the 80% - 125% limits for these parameters, we conclude that there is a significantly pharmacokinetic interaction of lansoprazole when it is administered concomitantly with hyoscine butylbromide.
