A phase I study of the oral platinum agent satraplatin in sequential combination with capecitabine in the treatment of patients with advanced solid malignancies.

Abstract Background. The broad spectrum of antitumor activity of both the oral platinum analogue satraplatin (S) and capecitabine (C), along with the advantage of their oral administration, prompted a clinical study aimed to define the maximum tolerated dose (MTD) of the combination. Patients and methods. Four dose levels of S (mg/m(2)/day) and C (mg/m(2)/day) were evaluated in adult patients with advanced solid tumors: 60/1650, 80/1650, 60/2000, 70/2000; a course consisted of 28 days with sequential administration of S (days 1-5) and C (days 8-21) followed by one week rest. Results. Thirty-seven patients were treated, 24 in the dose escalation and 13 in the expansion phase; at the MTD, defined at S 70/C 2000, two patients presented dose limiting toxicities: lack of recovery of neutropenia by day 42 and nausea with dose skip of C. Most frequent toxicities were nausea (57%), diarrhea (51%), neutropenia (46%), anorexia, fatigue, vomiting (38% each). Two partial responses were observed in platinum sensitive ovarian cancer and one in prostate cancer. Conclusion. At S 70/C 2000 the combination of sequential S and C is tolerated with manageable toxicities; its evaluation in platinum and fluorouracil sensitive tumor types is worthwhile because of the easier administration and lack of nephro- and neurotoxicity as compared to parent compounds.

Early vitamin K deficiency bleeding after maternal phenobarbital intake: management of massive intracranial haemorrhage by minimal surgical intervention.

Vitamin K deficiency bleeding within the first 24 h of life is caused in most cases by maternal drug intake (e.g. coumarins, anticonvulsants, tuberculostatics) during pregnancy. Haemorrhage is often life-threatening and usually not prevented by vitamin K prophylaxis at birth. We report a case of severe intracranial bleeding at birth secondary to phenobarbital-induced vitamin K deficiency and traumatic delivery. Burr hole trepanations of the skull were performed and the subdural haematoma was evacuated. Despite the severe prognosis, the infant showed an unexpected good recovery. At the age of 3 years, neurological examinations were normal as was the EEG at the age of 9 months. CT showed close to normal intracranial structures. CONCLUSION: This case report stresses the importance of antenatal vitamin K prophylaxis and the consideration of a primary Caesarean section in maternal vitamin K deficiency states and demonstrates the successful management of massive subdural haemorrhage by a limited surgical approach.

Ciclofosfamida oral metronómica en combinación con prednisona tras la progresión a docetaxel en pacientes afectados de un cáncer de próstata metastásico resistente a la castración (CPRC).

Estudi retrospectiu que avalua eficàcia i tolerabilitat de ciclofosfamida oral metronòmica (COM) més prednisona en CPRC com a segona línia de tractament després de la progressió a docetaxel. Quinze pacients foren tractats. L'objectiu principal fou eficàcia del tractament. Els objectius secundaris eren toxicitat, període lliure de progressió (PLP) i supervivència global (SG). La resposta parcial per PSA es va evidenciar en 33.3%. La mitjana del PLP i SG van ser de 4.1 mesos i 7.2 mesos respectivament. La principal toxicitat va ser l'astènia. COM és poc tòxica i pot ser una alternativa en aquells malalts amb mal estat

Oxidative and nonoxidative glucose metabolism following graded doses of oral glucose in man.

The oxidative and nonoxidative glucose metabolism represent the two major mechanisms of the utilization of a glucose load. Eight normal subjects were administered oral loads of 50, 100 and 150 g glucose and gas exchange measurements were performed for eight hours by means of computerized continuous indirect calorimetry. The glycemic peaks were almost identical with all three doses with a rise to between 141 and 147 mg/dl at 60 min. The fall back to basal level was reached later with the high than with the low glucose doses. The glucose oxidation rate rose to values between 223 and 253 mg/min after the three glucose doses, but while falling immediately after the peak at 120 min following the 50 g load, the glucose oxidation rate remained at its maximum rate until 210 min for the 100 g glucose load and plateaued up to 270 min for the 150 g glucose dose. The oxidation rates then fell gradually to reach basal levels at 270, 330 and 420 min according to the increasing size of the load. Altogether 55 +/- 3 g glucose were oxidized during the 8 hours following the 50 g glucose load, 75 +/- 3 g after the 100 g load and 80 +/- 5 g after the 150 g load. The nonoxidative glucose disposal, which corresponds essentially to glucose storage, varied according to the size of the glucose load, with uptakes of 20 +/- 1, 60 +/- 1 and 110 +/- 1 g glucose 180 min after the 50, 100 and 150 g glucose loads respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Swallowing difficulties with oral drugs among polypharmacy patients attending community pharmacies.

Background Swallowing difficulties are common and can affect patients' ability to take solid oral dosage forms, thus compromising medication adherence. Strategies developed by patients to overcome such difficulties while taking medicines have seldom been described. Objective To determine prevalence and characteristics of swallowing difficulties among primary care patients attending their community pharmacies; to explore strategies developed by patients to overcome their difficulties, and health professionals' awareness of these problems. Setting Prospective study with a semi-structured questionnaire in random community pharmacies located in two Swiss regions. Method In each pharmacy, an interviewer asked 16 questions to each consecutive patient (18 years and older) with a prescription for at least 3 different solid oral forms. Main outcome measure Quantification of number of patients with swallowing difficulties and detailed description of difficulties. Results Among 122 pharmacies, 59 (48 %) accepted to join the study and 410 patients were enrolled. Thirty-seven patients (9.0 %) reported ongoing swallowing difficulties, while 55 patients (13.4 %) reported past difficulties. For the majority of patients, difficulties occurred at each single dose (83.7 %), with a single medication (59.8 %) and lasted for less than 12 months (53.8 %). Number of tablets was not the main trigger. Swallowing difficulties impaired extremely daily life in 12 % of the patients. Intentional non adherence (23 % of patients) and altering the oral dose formulation were the most common and potentially harmful strategies used by patients to overcome their swallowing difficulties. According to the patients, pharmacists and physicians rarely inquired about their swallowing difficulties. Conclusion We report a fairly high prevalence of swallowing difficulties in polypharmacy patients attending their community pharmacies. Pharmacists have to interview patients on their swallowing difficulties in a more systematic way, support patients in finding solutions and refer them to their physician if necessary to ensure continuity in care.

Analysis of parity between protein-based electrophoretic methods for the characterization of oral Candida species

Electrophoretic studies of multilocus-enzymes (MLEE) and whole-cell protein (SDS-PAGE) were carried out in order to evaluate the parity between different methods for the characterization of five Candida species commonly isolated from oral cavity of humans by numerical taxonomy methods. The obtained data revealed that sodium dodecyl sulfate polyacrylamide gel electrophoresis is more efficient in grouping strains in their respective species while MLEE has much limited resolution in organizing all strains in their respective species-specific clusters. MLEE technique must be regarded for surveys in which just one species of Candida is involved.

Incidencia y gravedad de la enfermedad por citomegalovirus en pacientes trasplantados renales que han recibido tratamiento anticipado o profilaxis con valganciclovir oral

Antecedentes: La infección por CMV es la más frecuente que sufren los receptores de trasplante de órgano sólido (TOS) en los primeros meses del trasplante. Son abundantes las estrategias de prevención y tratamiento de la enfermedad por CMV que se han desarrollado. Métodos: El objetivo fue evaluar la incidencia y severidad de la enfermedad por CMV en 387 receptores de trasplante renal que recibieron tratamiento profiláctico (grupo de alto riesgo, n = 251) o realizaron seguimiento de PCR de CMV por ser grupo de bajo riesgo (n = 136) y recibieron tratamiento anticipado (n = 17) con valganciclovir oral (900 mg/día) cuando presentaron & 1000 copias/ml. Resultados: Presentaron enfermedad por CMV, 2 (11,76%) pacientes del grupo de riesgo estándar, descrita como enfermedad leve y 20 (7,96%) pacientes del grupo de alto riesgo, descrita como enfermedad leve en 15 casos y como enfermedad grave en 5 casos. Aquellos pacientes que desarrollaron la enfermedad, respondieron al tratamiento con ganciclovir endovenoso durante 14 días seguido de valganciclovir oral hasta completar tres meses. Conclusión: El tratamiento profiláctico con valganciclovir oral para la prevención de enfermedad o infección por CMV solamente es necesario en los receptores de TOS de alto riesgo.

An examination of male and female odds ratios by BMI, cigarette smoking, and alcohol consumption for cancers of the oral cavity, pharynx, and larynx in pooled data from 15 case-control studies.

BACKGROUND: Greater tobacco smoking and alcohol consumption and lower body mass index (BMI) increase odds ratios (OR) for oral cavity, oropharyngeal, hypopharyngeal, and laryngeal cancers; however, there are no comprehensive sex-specific comparisons of ORs for these factors. METHODS: We analyzed 2,441 oral cavity (925 women and 1,516 men), 2,297 oropharynx (564 women and 1,733 men), 508 hypopharynx (96 women and 412 men), and 1,740 larynx (237 women and 1,503 men) cases from the INHANCE consortium of 15 head and neck cancer case-control studies. Controls numbered from 7,604 to 13,829 subjects, depending on analysis. Analyses fitted linear-exponential excess ORs models. RESULTS: ORs were increased in underweight (<18.5 BMI) relative to normal weight (18.5-24.9) and reduced in overweight and obese categories (>/=25 BMI) for all sites and were homogeneous by sex. ORs by smoking and drinking in women compared with men were significantly greater for oropharyngeal cancer (p < 0.01 for both factors), suggestive for hypopharyngeal cancer (p = 0.05 and p = 0.06, respectively), but homogeneous for oral cavity (p = 0.56 and p = 0.64) and laryngeal (p = 0.18 and p = 0.72) cancers. CONCLUSIONS: The extent that OR modifications of smoking and drinking by sex for oropharyngeal and, possibly, hypopharyngeal cancers represent true associations, or derive from unmeasured confounders or unobserved sex-related disease subtypes (e.g., human papillomavirus-positive oropharyngeal cancer) remains to be clarified.

Improvement of chronic congestive heart-failure by oral captopril

Catopril, an inhibitor of angiotensin converting enzyme, was given orally during cardiac catheterisation to 6 normotensive patients with refractory congestive heart-failure. 60--180 minutes after administration of 25 mg captopril, arterial pressure fell by 25%, cardiac index rose by 38%, and left-ventricular pressure and right-atrial pressure fell by 25% and 40% respectively. Plasma-renin activity rose while plasma noradrenaline and aldosterone fell. These data suggest that, in the short term, captopril can reduce both preload and afterload, and improve cardiac function, in refractory congestive heart-failure.
