Design and validation of a home care satisfaction questionnaire: SATISFAD

OBJECTIVES: To design and validate an instrument to assess satisfaction with home care services, in both self-administered and telephone versions. METHODS: We performed a cross-sectional observational study of the population using home care services in the health districts of Malaga, Costa del Sol, Almeria and Granada (Spain). A questionnaire was designed by an expert panel using a Deplhi technique. Reliability between the self-administered and telephone versions was analyzed. Finally, internal consistency and construct validity were assessed. RESULTS: Reliability between the self-administered and telephone versions was high (intraclass correlation coefficient = 0.876; 95% CI, 0.726-0.941; p = 0.0001). Internal consistency was adequate (Cronbach's alpha: 0.853 and 0.799 for both versions, with or without caregiver, respectively). The factorial analysis explained 66.80% and 67.81% of the observed variance for the two versions (with or without caregiver, respectively). Two factors were isolated and related to interpersonal relationships, the role of the carer, and decision making. CONCLUSION: Assessment of satisfaction with home care can be performed with the dimensions routinely used in satisfaction studies, but these should be evaluated with instruments designed ad hoc. Accessibility, communication and interpersonal relationships have a high explanatory value in satisfaction among this population.     

Effects of a stable analogue of PGE2 (11-deoxy-13,14-didehydro-16 (S)-methylester methyl PGE2: FCE 20700) on the secretory processes of conjunctival goblet cells of rabbit

The effects of the instillation of a PGE2-analogue (11-deoxy-13,14-didehydro-16 (S)-methyl PGE2 methylester: FCE 20700) in the conjunctival sac of the rabbit were studied by means of two methods. The former is a clinical study (Dohlman test), the latter is a morphological investigation (semithin sections) on specimens of the conjunctival mucosa. From both methods it was possible to demonstrate that the FCE 20700 instillation enhanced the mucous lacrimal secretion in rabbits.     

Brachial approach to emergency cardiac catheterization during thrombolytic therapy for acute Myocardial Infarction

The use of the brachial approach to acute coronary intervention has not been previously studied. In the course of the Thrombolysis and Angioplasty in Myocardial Infarction (TAMI) trials, we used the transbrachial approach to cardiac catheterization with or without angioplasty in 202 of 704(28.6%) patients. The baseline characteristics of age, sex, risk factors, medical history, time from symptom onset to therapy, and left ventricular function were similar for the 2 different approaches. Time from therapy to coronary angiography was not delayed by the brachial approach compared with the femoral approach: 97.1±26 min vs. 99.9±133.8 min, respectively. Chemical patency was established in 78 vs. 73% of patients and technical success with acute PTCA with the brachial approach was 89% vs. 78% with the femoral approach. Clinical outcomes were quite similar with respect to death(6 vs. 6%), reocclusion (10 vs. 14%), and emergency coronary bypass surgery (5 vs. 6%). Baseline hematocrit was 43.9±4.4 and 43.5±4.8, respectively with a nadir of 32.9±5.6 vs. 33.0±5.4. The need for vascular repair occurred in 1% vs. 3% of patients and retroperitoneal hemorrhage was documented in 1% vs. 1% of patients. This study indicates that in thehands of experienced operators the transbrachial approach to acute coronary intervention in theacute phase of treatment with thrombolytic therapy can be used with equal risks and efficacy asthe femoral approach.     

Urban air pollution and respiratory emergency visits at pediatric unit, Reggio Emilia, Italy

Short-term effects of air pollution on daily mortality and hospital admissions for respiratory causes are well documented. Few studies, however, explore the association between exposure to air pollution and daily emergency room visits for respiratory disorders, particularly in Italy and particularly among children as a susceptible population. A time-series analysis was conducted to explore the short-term association between air pollutants (PM10, total suspended particulates [TSP], NO2, SO2, CO, O3) and pediatric emergency room (ER) visits in a small city of northern Italy, Reggio Emilia, during the period 03/01/2001-03/31/2002. There were 1051 ER visits included in the study. Data were analyzed using generalized additive models (GAM), adjusting for various confounding variables, including temperature, humidity, and pollens (Graminaceae). The analyses were also stratified according to the nationality of children (Italians and foreigners). In single-pollutant models, the strongest associations were observed at lag 3 for a 10-microg/m3 increase of TSP (2.7% increase in ER, 95% CI 0.7-4.6) and PM10 (3.0% increase, 95% CI 0.4-5.7), and at lag 4 for a 10-microg/m3 increase of NO2 (11.0% increase in ER, 95% CI 3.6-18.8). At lag 3, the percentage increase in ER visits is similar for the 2 groups of children (Italians and foreigners) for TSP and PM10. The results of the study support the findings that air pollution is a relevant determinant of deterioration of respiratory health among children.     

Evaluation of refrigerated platelet concentrates supplemented with low doses of second messenger effectors

With the goal of producing haemostatically effective platelet concentrates (PCs) with a longer shelf-life, we aimed to identify a simple combination of platelet inhibitors, with a low pharmacological load, which could avoid the unacceptable loss of platelets stored under refrigerated conditions. PCs stored with different combinations of second messenger effectors were analysed at days 5, 10 and 15 of storage and compared with those supplemented with ThromboSol--a combination of six platelet inhibitors that protects cells from cold damage. The following parameters were analysed: platelet counts, biochemical parameters (glucose, pH, bicarbonate, lactate), cell lysis (lactic dehydrogenase, LDH), membrane glycoproteins (GPs), platelet aggregation, fibrinogen binding and hypotonic shock response. We characterized the combination of amiloride and sodium nitroprusside (at 1/2 the dose included in ThromboSol). This was found to be similar to ThromboSol and superior to nontreated units in the prevention of cold-induced platelet aggregation at day 15 of storage (maintenance of 78% and 80% of initial platelet counts, respectively), preservation of GPIbalpha (11% and 12% better maintenance of mean fluorescence intensity compared with control units, respectively), and reduced cell lysis (13% and 11% decrease in supernatant LDH, respectively). The reduced pharmacological load with the identified solution compared with ThromboSol is an argument in favour of the potential use of these agents when designing strategies to improve PC storage.     

Utility of omentoplasty for poststernotomy mediastinitis secondary to myocardial revascularization surgery

Acute poststernotomy mediastinitis is a serious complication of cardiac surgery and is associated with high mortality. Conservative treatment with local debridement, irrigating-suction systems, and specific antibiotic therapy is sometimes inadequate. Omentoplasty is occasionally used for reconstruction and the treatment of various chest diseases. This useful procedure is most often indicated for suppurative processes and radionecrosis, to complement myoplasty, or to cover a chest wall prosthesis. When used to treat poststernotomy mediastinitis secondary to cardiac surgery, omentoplasty improves control of infection and prognosis. We describe 2 cases of poststernotomy mediastinitis secondary to cardiac revascularization surgery in which omentoplasty was an effective treatment. Excellent control of infection was achieved.     

Prospective randomised clinical trial of single versus double purse-string stapled mucosectomy in the treatment of prolapsed haemorrhoids

Background and aims Despite the excellent results published on circular stapled mucosectomy (CSM), there is still some concern about the application of PPH-33 in the advanced haemorrhoidal disease, where a major prolapse may lead to insufficient resection and ensuing early recurrence. This study is aimed at comparing the outcomes after single purse-string CSM versus double purse-string CSM.Patients and methods A prospective randomised clinical trial of single versus double purse-string CSM for grade III–IV symptomatic haemorrhoids was used. One hundred consecutive patients were randomised to single (group 1, N=50) versus double purse-string CSM (group 2, N=50).Results The mean age was 50.7 years, with a predominance of males (63 vs. 37). Haemorrhoids were classified as grade III in 59% and grade IV in 41% of the patients. Mean follow-up was 26 months. Demographic and clinical features showed no differences between the two groups. The size of the resected doughnut was greater in group 2 (4.95 vs. 3.55 cm; p<0.05), as was the distance of the suture from the dentate line (3.56 vs. 3.16 cm; p<0.05). Early postoperative pain was significantly less in group 2 (linear analogue scale from 0 to 10), 2.08 vs. 3.56 (p<0.001). Postoperative haemorrhage was absent or minimal in 79% of patients. Three patients from group 1 reported persistent pain that was resolved within the first few postoperative months. There were two recurrences in group 1.Conclusion Double purse-string CSM resects a greater doughnut, increases the distance of the staple suture from the dentate line and reduces early postoperative pain in comparison to single purse-string CSM. Larger series are necessary to assert whether recurrence is lower.     

Thalidomide, dexamethasone, and pegylated liposomal doxorubicin (ThaDD) for patients older than 65 years with newly diagnosed multiple myeloma

We present the results of a phase 2 study using thalidomide, dexamethasone, and pegylated liposomal doxorubicin (ThaDD) in the treatment of 50 patients older than 65 years with newly diagnosed multiple myeloma. Thalidomide 100 mg was administered orally at bedtime continuously, dexamethasone 40 mg was administered orally on days 1 to 4 and 9 to 12, and pegylated liposomal doxorubicin 40 mg/m2 was administered intravenously on day 1 over the 28-day cycle. Response was assessed according to the EBMT criteria. Seventeen (34%) patients achieved CR, 7 (14%) nCR, 5 (10%) VGPR, 15 (30%) PR, and 5 (10%) MR, resulting in an ORR of 98%. Only 1 patient (2%) presented progressive disease. Time to progression (TTP), event-free survival (EFS), and overall survival (OS) projected at 3 years were 60%, 57%, and 74%, respectively, and these parameters were significantly higher in those patients achieving a response of at least VGPR versus those who did not. Grade 3 and 4 nonhematologic adverse events were constipation (10%), fatigue (6%), tremors (4%), mucositis (4%), and palmar-plantar erythrodysesthesia (2%). Grade 3 and 4 neutropenia occurred in 12% of patients. Grade 3 and 4 infections and thromboembolic accidents were observed in 22% and 14% of patients, respectively. In the treatment of elderly patients with newly diagnosed multiple myeloma, ThaDD is a very effective regimen with manageable toxicity.     

Long-term results of botulinum toxin for the treatment of chronic anal fissure: prospective clinical and manometric study

Background The aim of this prospective trial was to analyse the effectiveness and morbidity of chemical sphincterotomy in the treatment of chronic anal fissure after a 3-year follow-up.Methods One hundred consecutive patients with chronic anal fissures were treated by chemical sphincterotomy with 25 U botulinum toxin injected into the internal sphincter. Clinical and manometric results were recorded.Results No major complications were found; initial incontinence at the 2-month review (6%) spontaneously reversed at 6 months. There was a tendency of progressive recurrence over time, with an overall healing after 3 years of 47%. We found a group of patients with clinical (symptoms longer than 12 months and presence of a sentinel pile before treatment) and manometric factors (persistently elevated mean resting pressure, percentage of time with slow waves, and number of patients or percentage of time with ultra slow waves after treatment) associated with a higher recurrence of anal fissures.Conclusion Since it avoids the greater risk of incontinence associated with surgical sphincterotomy, we recommend the use of botulinum toxin as the first therapeutic approach for patients with chronic anal fissure and risk factors for incontinence; despite the higher rate of recurrence associated with this treatment. In patients with factors related to recurrence, re-injection with higher doses of botulinum toxin or complementary medical–surgical treatment should be considered.
