Attitudes of hemodialysis patients,medical and nursing staff towards patients’ physical activity

International Urology and Nephrology - Patients with end-stage renal disease (ESRD) seem to have a negative attitude towards physical activity, which is mainly favored by the lack of counseling...     

Fingers,hands or patients? The concept of independent observations

In hand surgery trials, it is often possible to take several measurements from the same patient, because many disorders here affect bilateral or multiple structures, such as the hand itself, the finger joints or the tendons. Most conventional statistical analyses that take place on the level of hands, digit rays or joints rather than patients violate the assumption that observations should be independent. Furthermore, ignoring the multiplicity of data inflates sample size and thus may lead to spurious significance. This article describes three options to deal with such problems. First, the analysis can simply be restricted to only one measurement per patient. Second, a self-controlled design may be advantageous for conditions that usually have a bilateral pattern. Third, complex statistical modelling (involving generalized estimating equations) can be used to analyse all available measurements with adjustment for data dependency.     

Efficacy, tolerability, and safety of risedronate in Japanese patients with Paget’s disease of bone

This study evaluated the clinical efficacy of treatment with oral risedronate (17.5 mg once daily) for 8 weeks in 11 Japanese patients with Paget’s disease of bone (PDB). Risedronate suppressed the excessive bone turnover associated with PDB and improved several biochemical markers, including serum alkaline phosphatase (ALP), serum bone-specific ALP (BALP), urinary deoxypyridinoline (DPD), and urinary cross-linked N-telopeptide of type 1 collagen (NTX). These markers began to decrease within about 2 weeks after the initiation of treatment in most patients, and the response persisted for up to 40 weeks after the cessation of treatment. Risedronate reduced pain by week 24 in most patients. According to quantitative bone scintigraphy, the lesion with the highest radioisotope (RI) uptake showed a decrease of uptake from 12.7 ± 6.8 to 6.0 ± 2.3 (mean ± SD) in week 24, although each lesion of patients with polyostotic disease had a different scintigraphic response. Overall, risedronate at a dose of 17.5 mg once daily was well tolerated by patients with PDB, even though the dosage was seven times higher than that approved for the treatment of osteoporosis in Japan (2.5 mg once daily). In conclusion, treatment with high-dose risedronate for 8 weeks resulted in clinically significant and sustained improvement of biochemical markers of bone turnover for 48 weeks in patients with PDB, and this improvement was associated with a decrease of RI uptake by Paget’s bone lesions and with reduced pain.     

The bothersomeness of sciatica: patients’ self-report of paresthesia, weakness and leg pain

The objective of the study was to investigate how patients with sciatica due to disc herniation rate the bothersomeness of paresthesia and weakness as compared to leg pain, and how these symptoms are associated with socio-demographic and clinical characteristics. A cross-sectional study was conducted on 411 patients with clinical signs of radiculopathy. Items from the Sciatica Bothersomeness Index (0 = none to 6 = extremely) were used to establish values for paresthesia, weakness and leg pain. Associations with socio-demographic and clinical variables were analyzed by multiple linear regression. Mean scores (SD) were 4.5 (1.5) for leg pain, 3.4 (1.8) for paresthesia and 2.6 (2.0) for weakness. Women reported higher levels of bothersomeness for all three symptoms with mean scores approximately 10% higher than men. In the multivariate models, more severe symptoms were associated with lower physical function and higher emotional distress. Muscular paresis explained 19% of the variability in self-reported weakness, sensory findings explained 10% of the variability in paresthesia, and straight leg raising test explained 9% of the variability in leg pain. In addition to leg pain, paresthesia and weakness should be assessed when measuring symptom severity in sciatica.     

Patient’s anxiety and fear of anesthesia: effect of gender, age, education, and previous experience of anesthesia. A survey of 400 patients

Purpose

Patients express high anxiety preoperatively, because of fears related to anesthesia and its implications. The purpose of this survey was to gain insight into these fears and to study whether they are affected by patients’ sex, age, education, or previous experience of anesthesia.

Methods

Questionnaires with fixed questions were distributed to consenting, consecutive surgical patients before the pre-anesthetic visit. The questionnaires included patients’ demographics and questions related to their fears about anesthesia.

Results

Four-hundred questionnaires were collected and analyzed. Eighty-one percent of patients experience preoperative anxiety. The main sources of their anxiety were fear of postoperative pain (84 %), of not waking up after surgery (64.8 %), of being nauseous or vomiting (60.2 %), and of drains and needles (59.5 %). Patients are less concerned about being paralyzed because of anesthesia (33.5 %) or of revealing personal issues (18.8 %). Gender seems to affect patients fears, with women being more afraid (85.3 vs. 75.6 % of men, p = 0.014). The effects of patients’ age, level of education, and previous experience of anesthesia are minor, except for individual questions. Sixty-three percent of our patients (mostly women 67.4 vs. 57.4 % of men, p = 0.039) talk about these fears with their relatives, although a vast majority of 95.5 % would prefer to talk with the anesthesiologist and be reassured by him.

Conclusion

All patients, mostly women, express fears about anesthesia; this fear leads to preoperative anxiety. Slight differences are observed for some individual questions among patients of different sex, education level, and previous experience of anesthesia.     

Socioeconomic correlates of trauma: An analysis of emergency ward patients in Yaoundé, Cameroon

IntroductionInjury is a significant and increasingly common cause of morbidity and mortality in sub-Saharan Africa; however, the social and economic factors underlying these trends are not well understood. We evaluated the relationship between socioeconomic status (SES) and trauma outcomes using a prospective registry of patients presenting to the largest trauma hospital in Yaoundé, Cameroon.MethodsTrauma patients (n = 2855) presenting to the emergency ward at Central Hospital, Yaoundé between April 15 and October 15, 2009 were surveyed regarding demographic and socioeconomic background, nature and severity of injuries, treatment, and disposition. A wealth score was estimated for each patient, corresponding to an SES index constructed using principle components analysis of the urban Cameroonian Demographic and Health Survey. Logistic regression was used to evaluate the effects of SES on care-seeking behaviour, injury severity, and treatment outcome.Main outcome measures: SES wealth score, care-seeking prior to visiting hospital, injury severity, treatment outcome.ResultsPatients aged 1–89 presented with road traffic injuries (59.83%), falls (7.76%), and penetrating trauma (6.16%), and had higher SES than the broader urban Cameroonian population. Within the Yaoundé sample, being in the lowest SES quintile was associated with an increased likelihood of having sought care elsewhere before presenting to the hospital (aOR = 3.28, p < 0.001), after controlling for background and injury characteristics. Patients in the lowest SES quintile were also more likely to present with moderate/severe injuries (aOR = 4.93, p < 0.001), and were more likely to be transferred to the operating room.ConclusionsPatients presenting to this trauma centre were wealthier than the broader community, suggesting the possibility of barriers to accessing care. Poorer patients were more likely to have severe injuries and more likely to need surgery, but were less likely to seek care from a major trauma centre immediately. Substantial differences in SES between the sample visiting the hospital and the broader community suggest a need for community-based sampling approaches in future trauma research.     

Cytogenetic analysis of patients with amenorrhea

Objective: To analyse the cytogenetic examination results and investigate the effect of chromosome abnormalities on amenorrhea.Methods: The routine cytogenetic analysis was performed, including the chromosome G band analysis and karyotype analysis of the cultured peripheral blood lymphocytes from the patients with primary amenorrhea or secondary amenorrhea.Results: One hundred and thirty-seven cases were found with chromosome abnormalities in 234 patients with primary amenorrhea. The incidence of chromosome abnormality was 58.6%. In 309 with secondary amenorrhea, the incidence of chromosome abnormality was 13.6%.The reported abnormalities included the numerical and structural abnormalities of X chromosome, 46,XY, 45,X0/46,XY,and the structural abnormality of autosome.Conclusions: Chromosome abnormality is one of the main causes of amenorrhea. Karyotype analysis of chromosome is absolutely necessary for the diagnosis and treatment of patient with amenorrhea.     

Functional outcomes,quality of life,sexual function,and fertility of adult patients undergoing ileo‐anal pouch anastomosis in childhood

BackgroundWe conducted a questionnaire-based study of pouch function, quality of life, sexual function, and fertility among patients who had undergone ileal pouch anal anastomosis (IPAA) in childhood and who are now more than 18 years old.MethodsA consecutive series of patients were asked to complete the following questionnaires: Pouch function score (PFS), short form 36 (SF-36), International index of erectile function (IIEF) (males), and Female sexual function index (FSFI) (females). Fertility in females was also assessed. Data are quoted as a median (SD).ResultsOf 144 patients who had IPAA, 101 were eligible, and 70 responded. Mean age at surgery was 14 years, and mean current age is 26 years. Most patients had either ulcerative colitis or familial adenomatous polyposis. The questionnaire was completed by 38/70 (54%). Median PFS score was 6 (5). SF-36 were lower than previous reports. Median FSFI was 30 (7.6), 84% of possible maximum. Median IIEF was 69, 92% of possible maximum. Successful conception was reported in 5/7 women who had tried. However, there were several miscarriages and two surgical emergencies during pregnancies.ConclusionsIPAA can be performed in childhood with similar pouch function to reported adult series. Quality of life appears poorer, but sexual function is maintained. There may be an association with adverse events in pregnancy.Level of evidenceIV.     

Resected adenocarcinoma of the pancreas— 616 patients: Results, outcomes, and prognostic indicators

This large-volume, single-institution review examines factors influencing long-term survival after resection in patients with adenocarcinoma of the head, neck, uncinate process, body, or tail of the pancreas. Between January 1984 and July 1999 inclusive, 616 patients with adenocarcinoma of the pancreas underwent surgical resection. A retrospective analysis of a prospectively collected database was performed. Both univariate and multivariate models were used to determine the factors influencing survival. Of the 616 patients, 526 (85%) underwent pancreaticoduodenectomy for adenocarcinoma of the head, neck, or uncinate process of the pancreas, 52 (9%) underwent distal pancreatectomy for adenocarcinoma of the body or tail, and 38 (6%) underwent total pancreatectomy for adenocarcinoma extensively involving the gland. The mean age of the patients was 64.3 years, with 54% being male and 91% being white. The overall perioperative mortality rate was 2.3%, whereas the incidence of postoperative complications was 30%. The median postoperative length of stay was 11 days. The mean tumor diameter was 3.2 cm, with 72 % of patients having positive lymph nodes, 30% having positive resection margins, and 36% having poorly differentiated tumors. Patients undergoing distal pancreatectomy for left-sided lesions had larger tumors (4.7 vs. 3.1 cm, P <0.0001), but fewer node-positive resections (59% vs. 73%, P = 0.03) and fewer poorly differentiated tumors (29% vs. 36%, P<0.001), as compared to those undergoing pancreaticoduodenectomy for right-sided lesions. The overall survival of the entire cohort was 63% at 1 year and 17% at 5 years, with a median survival of 17 months. For right-sided lesions the 1- and 5-year survival rates were 64% and 17%, respectively, compared to 50% and 15% for left-sided lesions. Factors shown to have favorable independent prognostic significance by multivariate analysis were negative resection margins (hazard ratio [HR] = 0.64, confidence interval [CI] = 0.50 to 0.82, P = 0.0004), tumor diameter less than 3 cm (HR = 0.72, CI = 0.57 to 0.90, P = 0.004), estimated blood loss less than 750 ml (HR = 0.75, CI = 0.58 to 0.96, P = 0.02), well/moderate tumor differentiation (HR = 0.71, CI = 0.56 to 0.90, P = 0.005), and postoperative chemoradiation (HR = 0.50, CI = 0.39 to 0.64, P } < 0.0001). Tumor location in head, neck, or uncinate process approached significance in the final multivariate model (HR = 0.60, CI = 0.35 to 1.0, P = 0.06). Pancreatic resection remains the only hope for long-term survival in patients with adenocarcinoma of the pancreas. Completeness of resection and tumor characteristics including tumor size and degree of differentiation are important independent prognostic indicators. Adjuvant chemoradiation is a strong predictor of outcome and likely decreases the independent significance of tumor location and nodal status.

Post-traumatic osteolysis of the distal clavicle, pubis and ischium in 7 patients

Post-traumatic osteolysis (PTOL) is a very rare disease occurring after acute trauma or repetitive micro-trauma, which is characterized by persistent pain in the injured site. In this study, we reported 7 patients, in whom osteolysis developed in the distal clavicle, pubis and ischium.     

Daikenchuto,a traditional Japanese herbal medicine,for the maintenance of surgically induced remission in patients with Crohn’s disease: a retrospective analysis of 258 patients

Purpose

Despite numerous studies, the best postoperative therapy for Crohn’s disease is still undefined. We retrospectively evaluated the effects of postoperative maintenance therapy with daikenchuto, a traditional Japanese Kampo medicine, on the reoperation rate at 3 years in patients with Crohn’s disease.

Methods

A total of 258 patients who underwent surgery for Crohn’s disease were identified for the study. For the prevention of postoperative recurrence, patients were stratified to receive 5-aminosalicylic acid, azathioprine or daikenchuto, and their effects on preventing reoperation at 3 years were evaluated.

Results

Of the 258 patients, 44 required reoperation with intestinal resection within 3 years due to disease recurrence. The 3-year reoperation rate was significantly lower in the postoperative daikenchuto group than in the non-daikenchuto group (11.3 vs. 24.5 %, P = 0.01), and was similarly significantly lower in the postoperative 5-aminosalicylic acid group than in the non-5-aminosalicylic acid group (14.8 vs. 29.6 %, P = 0.0049). A multivariate Cox analysis showed that postoperative daikenchuto (P = 0.035) and postoperative 5-aminosalicylic acid (P = 0.022) were significantly and independently associated with the rate of reoperation at 3 years in patients with Crohn’s disease.

Conclusion

We propose that continuous daikenchuto therapy is a clinically useful and feasible maintenance therapy for the prevention of postoperative reoperation in patients with Crohn’s disease.

Assessment of the patients’ outcomes after implementation of South African triage scale in emergency department,Egypt

PurposeOvercrowding in emergency department (ED) is a concerning global problem and has been identified as a national crisis in some countries. Several emergency sorting systems designed successfully in the world. Launched in 2004, a group of branches in South African triage scale (SATS) developed. The effectiveness of the case sorting system of SATS was evaluated to reduce the patient's length of stay (LOS) and mortality rate within the ED at Suez Canal University Hospital.MethodsThe study was designed as an intervention study that included a systematic random sample of patients who presented to the ED in Suez Canal University Hospital. This study was implemented in three phases: pre-intervention phase, 115 patients were assessed by the traditional protocols; intervention phase, a structured training program was provided to the ED staff, including a workshop and lectures; and post-intervention phase, 230 patients were assessed by SATS. All the patients were retriaged 2 h later, calculating the LOS per patient and the mortality. Data was collected and entered using Microsoft Excel software. Collected data from the triage sheet were analyzed using the SPSS software program version 22.0.ResultsThe LOS in the ED was about 183.78 min before the intervention; while after the training program and the application of SATS, it was reduced to 51.39 min. About 15.7% of the patients died before the intervention; however, after the intervention the ratio decreased to 10.7% deaths.ConclusionSATS is better at assessing patients without missing important data. Additionally, it resulted in a decrease in the LOS and reduction in the mortality rate compared to the traditional protocol.     

Does preferential use of endovascular interventions by vascular surgeons improve limb salvage, control of symptoms, and survival of patients with critical limb ischemia?

BACKGROUND: Our approach to patients with critical limb ischemia (CLI) underwent a rapid evolution from open surgery to preferential use of endovascular procedures. The goal of the current report was to evaluate the impact of this change on patients with CLI. METHODS: Consecutive patients with CLI were compared between 3 periods: June 2001 to October 2002 (I) versus November 2002 to October 2003 (II) versus November 2003 to June 2005 (III). RESULTS: A total of 275 patients (301 limbs, mean age 70 +/- 11) underwent revascularization or primary major amputation (PA) for CLI (81 in I, 76 in II, 144 in III). PA decreased from 14.8%, 10.5%, and 3.5% (P < .001). Mean follow-up was 19.7 +/- 13.6 months (range 0 to 57). Overall 24-month limb salvage (LS) was 60%, 69%, and 85% (P = .001), and 71%, 77%, and 88% following LS attempt (P = .017), with no difference in survival. Length of stay (LOS) decreased from 10.7 +/- 12.1 (I) to 5.2 +/- 6.2 days (III) (P = .001). CONCLUSIONS: Preferential use of endovascular interventions in patients presenting with CLI resulted in decreased number of PA, improved LS, and decreased LOS, without a difference in survival.     

Is pulmonary resistance constant, within the range of tidal volume ventilation, in patients with ARDS?

When managing patients with acute respiratory distress syndrome(ARDS), respiratory system compliance is usually consideredfirst and changes in resistance, although recognized, are neglected.Resistance can change considerably between minimum and maximumlung volume, but is generally assumed to be constant in thetidal volume range (V_T). We measured resistance during tidalventilation in 16 patients with ARDS or acute lung injury bythe slice method and multiple linear regression analysis. Resistancewas constant within V_T in only six of 16 patients. In the remainingpatients, resistance decreased, increased or showed complexchanges. We conclude that resistance within V_T varies considerablyfrom patient to patient and that constant resistance withinV_T is not always likely. Br J Anaesth 2001; 86: 176–82
