IntroductionAn issue of recent research interest is excessive stoma output and its relation to electrolyte abnormalities. Some studies have identified this as a precursor of dehydration and renal dysfunction. A prospective study was performed of the complications associated with high-output stomas, to identify their causes, consequences and management.Materials and methodsThis study was carried out by a multidisciplinary team of surgeons, gastroenterologists, nutritionists and hospital pharmacists. High-output stoma (HOS) was defined as output ≥1500 ml for two consecutive days. The subjects included in the study population, 43 patients with a new permanent or temporary stoma, were classified according to the time of HOS onset as early HOS (<3 weeks after initial surgery) or late HOS (≥3 weeks after surgery). Circumstances permitting, a specific protocol for response to HOS was applied. Each patient was followed up until the fourth month after surgery.ResultsEarly HOS was observed in 7 (16 %) of the sample population of 43 hospital patients, and late HOS, in 6 of the 37 (16 %) non-early HOS population. By type of stoma, nearly all HOS cases affected ileostomy, rather than colostomy, patients. The patients with early HOS remained in hospital for 18 days post surgery, significantly longer than those with no HOS (12 days). The protocol was applied to the majority of EHOS patients and achieved 100 % effectiveness. 50 % of readmissions were due to altered electrolyte balance. Hypomagnesaemia was observed in 33 % of the late HOS patients.ConclusionThe protocol developed at our hospital for the detection and management of HOS effectively addresses possible long-term complications arising from poor nutritional status and chronic electrolyte alteration.
FMEA was useful for detecting medication errors in the PN preparation process and enabling corrective measures to be taken. A checklist was developed to reduce errors in the most critical aspects of the process.
IntroductionParaneoplastic pruritus is defined as pruritus that occurs before or during the natural evolution of a hematologic disease. The reported prevalence is 30% in patients with Hodgkin’s lymphoma. The severity of this pruritus has a very negative impact on patients’ quality of life. Very few studies have been made to examine the efficacy of pharmacological treatments for this type of pruritus. One drug that appears to be effective in this respect is off-label aprepitant, a neurokinin 1 receptor antagonist.Case presentationA 20-year-old Caucasian woman presented with lateral neck nodes, sweating, and pruritus and was diagnosed with stage IIB nodular sclerosis Hodgkin’s lymphoma. Throughout this period during the disease the pruritus was ever-present. Improvement was achieved with some of the chemotherapy treatments, but the symptom returned when the various treatments were withdrawn due to disease progression or poor tolerance. In the middle of the seventh year, she was admitted to our hospital with uncontrolled pruritus that resulted in severe lesions due to scratching. In response, aprepitant (off-label) 80mg/day was added to the chemotherapic treatment of the pruritus, after studying the various treatment options. She reported a score of 9 on a visual analogue scale for the pruritus, and a score of 3 on the Eastern Cooperative Oncology Group performance status scale of performance status. After two weeks of treatment with aprepitant, she reported a score of 5 on the visual analogue scale for the pruritus, and this improved to a score of 4 in a month, which allowed her to lead a better quality of life, with an Eastern Cooperative Oncology Group performance status score between 1 and 2.ConclusionsSeveral cases and case series have been reported on the use of aprepitant for paraneoplastic pruritus, but none have referred to its use for Hodgkin’s lymphoma. A prospective study was carried out to evaluate the efficacy of this drug in refractory pruritus secondary to Sezary syndrome, and other authors have studied the effectiveness of aprepitant against pruritus, secondary to biological therapy with erlotinib. In our case report, treatment was started with daily doses of aprepitant 80mg. Pruritus improvement appeared to be attributable exclusively to the administration of aprepitant.
Our study suggests that some toxic effects of docetaxel may be related to the excipients used in different formulations of the drug.
Modifications in the digestive tract secondary to gastrointestinal surgery may compromise the bioavailability of drugs. Decreased absorption surface, gastric emptying speed, and gastric pH alteration are factors to be taken into account in the management of pharmacological treatment after surgery. Evidence supported by data in clinical practice is scarce, but after studying the pharmacokinetic profile of some molecules, it is possible to offer recommendations for its adaptation to the patient's clinical situation.
Plantar warts are a common reason for dermatological consultations and their treatment can occasionally be a challenge. Plantar warts are benign lesions produced by the human papillomavirus (HPV) that often fail to respond to habitual treatment. Cidofovir is a potent antiviral drug that acts competitively, inhibiting viral DNA polymerase. Our aim was to assess the efficacy and safety of cidofovir cream for the treatment of viral plantar warts. We undertook a retrospective observational study of patients with plantar warts who received treatment with topical cidofovir between July 2008 and July 2011 at the Dermatology Service of the Hospital Costa del Sol, Marbella, Spain. Data about the rate of treatment response, the adverse effects, and recurrences, as well as the characteristics of the patient cohort, were recorded. We identified 35 patients who had received some previous treatment. The usual concentration was 3% (in 33 of 35 cases), applied twice a day (in 31 of 35 cases). A greater or lesser response was noted in 28 cases. There were two recurrences. Topical cidofovir seems to be a useful alternative for the therapeutic management of recalcitrant plantar common warts that fail to respond to usual treatment.
IntroductionOne of the most common complications of parenteral nutrition (PN) is liver dysfunction (LD). Therapeutic approaches for LD include, among others, administering cyclic parenteral nutrition (cPN), allowing some hours for metabolic rest. The purpose of this study was to evaluate the effectiveness of cPN in treating PN-associated LD.Materials and methodsA retrospective observational study was carried out at the Costa del Sol Hospital in Spain between 2013 and 2014. The study involved inpatients ≥18 years old prescribed with cPN due to the development of PN-associated LD. The hepatic biochemical parameters measured at baseline and after completion of cPN included aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP) and total bilirubin (TB). Quantitative values (age, biochemical parameters) were compared using matched Student’s t-test; the mean change in qualitative variables (sex, indication of PN, hepatic comorbidities, presence of insulin in cPN, infection during cPN, management of LD prior to cPN administrarion) was estimated using Mann-Whitney U test, and bivariate correlation between quantitative variables was determined by Spearman’s coefficient of correlation.ResultsThirty-seven patients met inclusion criteria. All hepatic function parameters except ALP improved after the administration of cPN, with statistically significant differences (p < 0.05) in AST GGT and TB.ConclusioncPN improves PN-associated LD by restoring abnormal AST, GGT, and BT levels to normal, and reducing ALT levels close to normal. The results obtained suggest that the administration of cPN is effective in reverting PN-associated LD.
Periungual warts represent a treatment challenge because of its high recurrence rate and recalcitrance. These are benign lesions produced by the human papilloma virus (HPV) that often do not respond to habitual treatment. Cidofovir is a potent antiviral drug that acts inactivating viral DNA polymerase. Topical cidofovir for the treatment of HPV-related cutaneous and mucous lesions is becoming increasingly common. Our aim was to assess the efficacy and safety of cidofovir cream for the treatment of viral periungual warts. We undertook a retrospective observational study of patients with periungual warts who received treatment with topical cidofovir between January 2010 and December 2013 at the Dermatology Service of the Hospital Costa del Sol, Marbella, Spain. Data were recorded about the rate of treatment response, the adverse effects and recurrences, as well as the characteristics of the patient cohort. We identified 41 patients who had received some previous treatment. The concentration of cidofovir was 3% in all cases, usually applied twice a day (in 37 of the 41 cases). A greater or lesser response was noted in 35 cases. There were six recurrences in the follow-up period. Topical cidofovir seems to be a useful alternative for the therapeutic management of recalcitrant periungual common warts that fail to respond to usual treatment. Our experience with the use of this antiviral agent has been satisfactory, although in our opinion, it should be reserved for specific cases as its economical cost represents an important limitation.
