Nearly 20,000 patients per year in the UK receive total knee arthroplasty (TKA). One of the problems faced by the health services of many developed countries is the length of time patients spend waiting for elective treatment. We therefore report the results of a study in which the Salisbury Priority Scoring System (SPSS) was used by both the surgeon and their patients to ascertain whether there were differences between the surgeon generated and patient generated Salisbury Priority Scores.
The Salisbury Priority Scoring System (SPSS) was used to assign relative priority to patients with knee osteoarthritis as part of a randomised controlled trial comparing the standard medial parapatellar approach versus the sub-vastus approach in TKA. The operating surgeons and each patient completed the SPSS at the same pre-assessment clinic. The SPSS assesses four criteria, namely progression of disease, pain or distress, disability or dependence on others, and loss of usual occupation. Crosstabs and agreement measures (Cohen's kappa) were performed.
Overall, the four SPSS criteria showed a kappa value of 0.526, 0.796, 0.813, and 0.820, respectively, showing moderate to very good agreement between the patient and the operating consultant. Male patients showed better agreement than female patients.
The Salisbury Priority Scoring System is a good means of assessing patients' needs in relation to elective surgery, with high agreement between the patient and the operating surgeon.
The aim of our study was to compare the effects of suprascapular nerve block in patients with frozen shoulder and diabetes mellitus unresponsive to intraarticular steroid injections.
Settings and Design:
Ten patients without improvement of sign and symptoms after intraarticular injections were made a suprascapular nerve block.
Pain levels and active range of movement of patients were recorded at initial attendance and after 1, 4, and 12 weeks. All patients’ simple pain scores, total pain scores, and range of motion of their shoulders were improved significantly after suprascapular nerve block.
In this study, the statistical analyses were performed by using the SPSS 8.0 program (SPSS Software, SPSS Inc., USA). To compare pre- and post-injection results of simple pain score, total pain score, shoulder abduction and external rotation, Wilcoxon test was used.
Patient's simple pain scores, total pain scores also abduction, external rotation and internal rotation angles were improved significantly after suprascapular nerve block.
Effective results after suprascapular nerve blockage was obtained for the treatment of refractory frozen shoulder cases.

Aim and Background:
Due to the relatively high prevalence of binocular vision anomalies, a regular examination including tests for assessment and determination of these anomalies is necessary. The aim of this study was to assess the relationship between near point of convergence (NPC) and near binocular vision symptoms and finding of an NPC cutoff point for symptoms in university students.
Materials and Methods:
In this cross-sectional study, 124 students of different majors of Zahedan University of Medical Sciences were randomly selected. If they met the inclusion criteria, they were divided into two groups (symptomatic and asymptomatic) according to the convergence insufficiency symptom survey questionnaire. For NPC measurement, a small isolated letter E of approximately 20/30 size on a metal rod was used. After data collection, data were analyzed in SPSS.17 software (SPSS for Windows, SPSS Inc., Chicago, IL) using descriptive and analytical statistics, including Mann–Whitney U test and receiver operating characteristic (ROC) curve.
The mean NPC findings in the symptomatic and asymptomatic groups were 11.7 ± 5.0 and 8.4 ± 3.4 cm, respectively, with a significant difference between the two groups (P < 0.001). The ROC curve suggests an NPC cutoff point of 9.5 cm for the presence of symptoms with the testing procedures used in this study.
The determination of NPC is helpful in the differentiation of symptomatic from asymptomatic subjects.

Long-term administration of home total parenteral nutrition (HTPN) has permitted patients with chronic intestinal failure to survive for prolonged periods of time. However, HTPN is associated with numerous complications, all of which increase morbidity and mortality. In Canada, a comprehensive review of the HTPN population has never been performed.
To report on the demographics, current HTPN practice and related complications in the Canadian HTPN population.
This was a cross-sectional study. Five HTPN programs in Canada participated. Patients’ data were entered by the programs’ TPN team into a Web site-based registry. A unique confidential record was created for each patient. Data were then downloaded into a Microsoft Excel (Microsoft Corp, USA) spreadsheet and imported into SPSS (SPSS Inc, USA) for statistical analysis.
One hundred fifty patients were entered into the registry (37.9% men and 62.1% women). The mean (± SD) age was 53.0±14 years and the duration requiring HTPN was 70.1±78.1 months. The mean body mass index before the onset of HTPN was 19.8±5.0 kg/m2. The primary indication for HTPN was short bowel syndrome (60%) secondary to Crohn’s disease (51.1%), followed by mesenteric ischemia (23.9%). Complications: over one year, 62.7% of patients were hospitalized at least once, with 44% of hospitalizations related to TPN. In addition, 28.6% of patients had at least one catheter sepsis (double-lumen more than single-lumen; P=0.025) and 50% had at least one catheter change. Abnormal liver enzymes were documented in 27.4% of patients and metabolic bone disease in 60% of patients, and the mean Karnofsky score was 63.
In the present population sample, the data suggest that HTPN is associated with significant complications and health care utilization. These results support the use of a Canadian HTPN registry to better define the HTPN population, and to monitor complications for quality assurance and future research.

Genetic polymorphisms in apolipoprotein genes may be associated with alteration in lipid profile and susceptibility to gallstone disease.
To determine the association between apolipoprotein A1 (APOA1) (−75 guanine [G] to adenine [A] and +83/84 M2+/−, MspI) and apolipoprotein C3 (APOC3) (SstI) polymorphisms with gallstone disease.
MspI polymorphisms of the APOA1 gene and SstI polymorphisms of APOC3 were analyzed in DNA samples of 214 gallstone patients and 322 age- and sex-matched healthy controls. All statistical analyses were performed using SPSS version 11.5 (SPSS, USA) and Arlequin version 2.0 (Arlequin, Switzerland).
The APOA1 −75 G/A polymorphism was significantly associated with gallstone disease. Patients with the GG genotype (P=0.015) and G allele carriers (P=0.004) had a significantly higher risk of gallstone disease (1.087-fold and 1.561-fold, respectively), whereas patients with AA genotypes (P=0.011) and A allele carriers (P=0.004) were protected (OR 0.230 and 0.641, respectively) against gallstone disease. APOA1 +83 M2+/− and APOC3 SstI polymorphisms were not associated with gallstone disease. Case-control analysis of haplotypes showed a significant association in males only. G-M2+-S1 conferred risk for gallstone disease (P=0.036; OR 1.593, 95% CI 1.029 to 2.464), while A-M2+-S1 was protective (P=0.002; OR 0.370, 95% CI 0.197 to 0.695) against gallstone disease. In APOA1−75-APOA1+83 bilocus haplotypes, G-M2+ was associated (P=0.0001) with very high risk (OR 3.173, 95% CI 1.774 to 5.674) for gallstone disease in males only. APOA1−75-APOC3SstI haplotypes also showed significant association while APOA1+83-APOC3SstI haplotypes showed no association with gallstone disease.
The APOA1 −75 G/A polymorphism is associated with gallstone disease and shows sex-specific differences. On the other hand, APOA1 M2+/− and APOC3 SstI polymorphisms may not be associated with gallstone disease. Haplotype analysis is a better predictor of risk for gallstone disease.

Background. Repeated measurements in a single subject are generally more similar than unrepeated measurements in different subjects. Unrepeated analyses of repeated data cause underestimation of the treatment effects.
Objective. To review methods adequate for the analysis of cardiovascular studies with repeated measures.
Results. (1) For between-subjects comparisons, summary measures and random-effects mixedlinear models are possible. Examples of summary measures include the area under the curve of drug time-concentration and time-efficacy curves, maximal values, mean values, and changes from baseline. A problem is that precision is lost because averages, rather than individual data, are applied. Random-effects mixed-linear models, available in SPSS statistical software and other software programmes, provide better precision for that purpose. (2) For within-subjects comparisons, repeated-measures ANOVAs are available in SPSS and other software programmes. Subgroup factors such as gender differences and age class can be included.
Discussion. For non-Gaussian data, Wilcoxon's and Friedman's tests are available, for binary data McNemar's tests can be used in case of two repeated observations. No standard methods are available for repeated binary measures with more than two observations. The purpose of this review was not to present a complete report but, rather, to underline that ample efforts should be made to account for the special nature of repeated measures.

The demand for vascular hemodialysis access creation is steadily increasing. To satisfy the demand, a vascular access team was established at the University Hospital of the West Indies, Jamaica. The outcomes of this practice are reported.
A retrospective study of all patients who had permanent vascular dialysis access established at the University Hospital of the West Indies between January 1, 2002, and December 31, 2006, was performed. Data were analyzed using SPSS version 12.0 (SPSS Inc, USA).
A direct anastomosis between an autogenous artery and vein was considered an arteriovenous fistula (AVF). When prosthetic material was used, the access was considered to be an arteriovenous graft. Accesses that were nonfunctional after six weeks of maturation were considered to be primary failures, while those that failed after previous successful dialysis were considered to be secondary failures. Primary patency was defined as the interval between access placement and the first intervention for failure. Secondary patency was the interval between access placement and abandonment. Cumulative patency was defined as the number of accesses that remained patent over a given time period, regardless of the number of interventions performed.
Of 41 patients, nine were excluded due to incomplete data. Final analyses were performed on 32 patients with a mean (± SD) age of 42.3±15.3 years (range 18 to 66 years, median 43 years). The access type was an AVF in 100% of cases, which included distal radiocephalic fistulas in 27 patients, brachial-cephalic fistulas in three patients and proximal radiocephalic fistulas in two patients. Operations were performed in four (12.5%) incident and 28 (87.5%) prevalent dialysis patients. The mean delay between initiation of dialysis and AVF creation was 21.2±26.1 months (range one to 94 months, median 10 months).
There were eight (25%) primary failures. Of the remaining 24 patients, there were seven (29.2%) secondary failures from thrombosis. There was primary patency for a mean of 723.9±422.1 days (range 199 to 1314 days, median 678 days). Only one (4.2%) patient had thrombectomy to prolong AVF function, resulting in secondary patency for 439 days. Cumulative patency was 62.5%, 33.3%, 25% and 4.2% for one, two, three and four years, respectively.
The rate of AVF creation for end-stage renal disease patients in this setting far exceeds the target goals set forward by the National Kidney Foundation published updated Dialysis Outcomes Quality Initiative (NKF/DOQI) Guidelines and the Centers for Medicaid & Medicare Services Fistula First initiative. This is being achieved with acceptable rates of morbidity and patency. There is room for improvement in postoperative surveillance to increase early detection of failing accesses and allow for increased utility of interventions for assisted patency.

In the Cayman Islands, a vascular access service was created in 2005 to facilitate the creation of vascular access for hemodialysis by local surgeons. The present retrospective audit aims to establish the outcomes of this practice in the Cayman Islands.
Data from the operative log of the Cayman Islands Hospital was collected over a period of 36 months. The data were analyzed using SPSS version 12.0 (SPSS Inc, USA). Statistical analyses were performed using Student’s t tests and Fisher’s exact tests.
A total of 19 operative procedures were performed to create vascular accesses in 12 men and seven women. Thirteen procedures (68%) created autogenous arteriovenous fistulas (AVFs) and six (32%) involved the insertion of a prosthetic arteriovenous graft (AVG). There were six incident dialysis patients, all of whom had an AVF created. The remaining 13 prevalent dialysis patients had new accesses in the form of AVFs (n=7) or AVGs (n=6).
The statistical analyses were limited by sample size, but with AVFs, there were trends toward reduced incidence of secondary failure (four of 13 versus four of six), thrombosis (four of 13 versus two of six), infectious morbidity (zero versus two of six) and less demand for interventions to maintain patency (one of 13 versus two of six) with AVFs. There were also trends toward superior primary (461 days versus 227 days) and secondary (803 days versus 205 days) patency rates for AVFs.
In this setting, the rate of AVF creation exceeds the goals set by the National Kidney Foundation Kidney Disease Outcomes Quality Initiative and the Fistula First Breakthrough Initiative. To ensure continued delivery of modern quality care, further audits of the local practice will be required at regular intervals.

Tobacco is the leading cause of mortality globally and in India. The magnitude and the pattern of tobacco consumption are likely to be influenced by the geographical setting and with rapid urbanization in India there is a need to study this differential pattern.
The aim was to study the rural, urban, and urban-slum differences in patterns of tobacco use.
The study was conducted in Ballabgarh block, Faridabad district, Haryana, and was a community-based cross-sectional study.
Materials and Methods:
The study was conducted in years 2003-2004 using the WHO STEPS approach with 7891 participants, approximately equal number of males and females, selected using multistage sampling from urban, urban-slum, and rural strata.
The analysis was done using the SPSS 12.0 statistical package (SPSS Inc., Chicago, IL, USA). Direct standardization to the WHO world standard population was done to and chi-square and ANOVA tests were used for comparison across three study settings.
Self-reported tobacco use among males was as follows: urban 35.2%; urban-slums 48.3%; and rural 52.6% (P value <0.05). Self-reported tobacco use among females was as follows: Urban 3.5%; urban-slums 11.9%; and rural 17.7% (P value <0.05). More males reported daily bidi (tobacco wrapped in temburini leaf) smoking (urban 17.8%, urban-slums 36.7%, rural 44.6%) than cigarette use (urban 9.6%, urban-slums 6.3%, rural 2.9%). Females using smoked tobacco were almost exclusively using bidis (urban 1.7%, 7.9%, 11% in rural). Daily chewed tobacco use had urban, urban-slum, and rural gradients of 12%, 10.5%, and 6.8% in males respectively. Its use was low in females.
The antitobacco policies of India need to focus on bidis in antitobacco campaigns. The program activities must find ways to reach the rural and urban-slum populations.

We compare the racial and ethnic demographics of our participants with the populations where our clinics are located (Texas and British Columbia) and investigate the reasons cited for participation.
We compared the distribution of participants by race/ethnicity to numbers from the 2000 United States Census and the 2001 Census of Canada. Each participant recorded her reasons for enrolling in the trial in her own words. This information was then categorized for analysis. For participants who provided more than one reason for participation, their responses were weighted accordingly to sum 100% for each race. All analyses were performed using SPSS v12.0 (SPSS, Inc, Chicago).
In all, 1,850 women participated in the study. Except for Asians in the Vancouver population and Native Americans in both populations, all minorities were recruited in proportions in excess of their respective proportions in the general population. Distinct differences in the reasons for participating between sites were noted. Houston patients were more likely to cite concern for one's own health as a reason for participating. On the other hand, Vancouver patients were more likely to cite helping others. This trend was found in both the screening and diagnostic populations.
We attribute our success in recruiting minorities to community outreach, our multicultural staff, and efforts to provide uniform care at all sites.

There are many combinations of treatments for pyogenic liver abscess (PLA). Different treatments are indicated for different clinical courses of PLA.
To realize the current prevalence, clinical course, trend of treatment, and prognosis of pyogenic liver abscess (PLA) in Taiwan.
We retrospectively reviewed the medical records of 126 patients with PLA. We divided them into four groups: M, MD, MS, and MDS, represented as parenteral antibiotic only, parenteral antibiotic with drainage, parenteral antibiotic with surgical intervention, and parenteral antibiotic with surgical drainage. We analyzed data by commercial statistical software (SPSS for Windows, version 11.0, SPSS Ltd., Chicago, IL). We used Student’s t-test and χ2 test for statistical analyses, and significance was set at a p value less than 0.05.
PLA patients who were treated only with parenteral antibiotics had early diagnosis of PLA with a mean fever period of 3.3 days (p = 0.043). Patients who needed surgical drainage were highly associated with shock presentation in the clinical course (35.7% versus 14.3%, p = 0.007).
The earlier we can diagnose PLA, the shorter the patient's hospital stay (20.6 days) will be. In PLA patients with shock, a higher rate of surgical intervention is mandatory to save their lives.

The association of age, sex and renal parenchymal damage (RPD) in vesicoureteral reflux (VUR) is well known. We compared various factors between infants and children in a cohort of patients with primary VUR.
Materials and Methods
Medical records of 147 patients diagnosed as VUR between 1997 and 2010 were reviewed. Of these children 91 (61.9%) were boys and 56 (38.1%) were girls. 99 (67.3%) of the 147 patients were younger (Group 1), and 48 (32.7%) were older than 1 year (Group 2). The impact of patient's gender and age as well as VUR grade on RPD were analyzed in each patient. The Fisher's exact test and chi square test was done with SPSS ver. 12.0 (SPSS Inc., Chicago, IL, USA).
VUR was unilateral in 88 patients (59.9%) and bilateral in 59 patients (40.1%). Abnormal renal scan was found in 78 (37.7%) renal units. The incidence of VUR was significantly higher in male in group 1 (p<0.01) and in female in group 2 (p<0.01). The incidence of abnormal renal scan was significantly higher in intermediate and high grade VUR comparing low grade VUR in group 1 (p=0.042). In both group, abnormal renal scan didn't show any difference between male and female statistically (p>0.05).
Our data showed that VUR in infant was significantly higher in male than in female, whereas VUR in children was significantly higher in female. This may be due to that characteristic of a population where neonatal circumcision is not a common procedure in infant and urinary tract infections are more common in female children. Further study may be needed to identify gender difference in RPD in infant with high grade reflux.

Family violence (FV) is a global health problem that not only impacts the victim, but the family unit, local community and society at large.
To quantitatively and qualitatively evaluate the treatment and follow up provided to victims of violence amongst immediate and extended family units who presented to three health centers in Mozambique for care following violence.
We conducted a verbally-administered survey to self-disclosed victims of FV who presented to one of three health units, each at a different level of service, in Mozambique for treatment of their injuries. Data were entered into SPSS (SPSS, version 13.0) and analyzed for frequencies. Qualitative short answer data were transcribed during the interview, coded and analyzed prior to translation by the principal investigator.
One thousand two hundred and six assault victims presented for care during the eight-week study period, of which 216 disclosed the relationship of the assailant, including 92 who were victims of FV. Almost all patients (90%) waited less than one hour to be seen, with most patients (67%) waiting less than 30 minutes. Most patients did not require laboratory or radiographic diagnostics at the primary (70%) and secondary (93%) health facilities, while 44% of patients received a radiograph at the tertiary care center. Among all three hospitals, only 10% were transferred to a higher level of care, 14% were not given any form of follow up or referral information, while 13% required a specialist evaluation. No victims were referred for psychological follow-up or support. Qualitative data revealed that some patients did not disclose violence as the etiology, because they believed the physician was unable to address or treat the violence-related issues and/or had limited time to discuss.
Healthcare services for treating the physical injuries of victims of FV were timely and rarely required advanced levels of medical care, but there were no psychological services or follow-up referrals for violence victims. The healthcare environment at all three surveyed health centers in Mozambique does not encourage disclosure or self-report of FV. Policies and strategies need to be implemented to encourage patient disclosure of FV and provide more health system-initiated victim resources.
Background and aim:
Despite the high prevalence of uterine leiomyoma, according to recent review studies there is uncertainty and a paucity of information regarding its predisposing or protective factors. The aim of this study was to assess the possible association between menstrual cycle pattern and occurrence of surgically treated myomas and also to check if depo-medroxyprogesterone acetate (DMPA) injection earlier in reproductive life can affect the later occurrence of myomas needing surgical treatment.
In a case–control study in Ardabil, 85 women with definite diagnosis of surgically treated uterine leiomyoma and 154 community controls were enrolled. Possible predictors of myoma including menstrual cycle and menstrual bleeding patterns were assessed. Data were analyzed using SPSS software (SPSS, IBM, Somers, NY). Odds ratios were used as the main statistic in assessing the strength of observed associations.
Mean age of the participants was 41.8 ± 8.5 years. Length of menstrual cycle was associated with myoma and a higher likelihood of myoma was observed among those having shorter menstrual cycles (P < 0.05). Number of menstrual bleeding days was also associated with surgically treated myoma and longer bleeding periods increased the likelihood of myoma (P < 0.05). Only one of the eight women who had a history of depo-medroxyprogesterone acetate injections had developed surgically treated uterine leiomyoma and the others belonged to the control group without a history of surgical treatment for uterine leiomyoma.
Menstrual cycle pattern is associated with developing leiomyomas requiring surgical treatment. DMPA, other than its role in myoma treatment, is also assumed to have a role in preventing myomas, but due to the small sample size in this study, larger scale prospective trials are needed in the future.

In oral implantology, there is no consensus on the most appropriate regimen for antibiotics prescribing, the decision to prescribe antibiotic is usually based on procedure, patient and clinician related factors. The aim of this study was to investigate the rationale of antibiotic prescribing among Jordanian clinicians who practice oral implantology.
The target sample for the study was the 250 Jordan Dental Implant Group members. A five page questionnaire contained 41 questions, both closed and open questions were used to collect data. Statistical analysis was performed using SPSS Windows 16.0 (SPSS Inc., Chicago, IL, USA). Descriptive statistics were generated.
The response rate was (70.4%) 176/250. Mean age was 37.2 yrs, 49.4% always prescribe antibiotics mainly oral amoxicillin and amoxicillin with clavulinic acid. Antibiotics prescribing increased with flap raising, multiple implants and sinus or bone augmentation. Patient medical condition, periodontitis and oral hygiene were the most important clinical factors in antibiotic prescribing, non-clinical factors were; reading scientific materials, courses and lectures, knowledge gained during training, and the effectiveness and previous experience with the drug.
Wide variations in antibiotics types, routes, dose and duration of administration were found. Recommendations on antibiotic prescribing are needed to prevent antibiotic overprescribing and misuse.

In this study, we evaluated the effect of photopolymerization on Vickers microhardness of dual-polymerized resin cement at three locations when a translucent quartz fiber post was used.
Materials and Methods:
Single-rooted bovine teeth received quartz fiber post systems (length: 12 mm) using a dual-polymerized resin cement. In Group 1, the posts were cemented but not photopolymerized, and in Group 2, the posts were both cemented and photopolymerized. After cementation, approximately 1.5-mm thick sections were obtained (two cervical, two middle, and two apical) for regional microhardness evaluations.
Statistical analyses were performed using the SPSS software (ver. 11.0 for Windows; SPSS, Inc., Chicago, IL, USA). Microhardness (kg/mm2) data were submitted to two-way analysis of variance (two-way ANOVA) and repeated measures with microhardness values as the dependent variable and polymerization status (two levels: with and without) and root region (three levels: cervical, middle, and apical) as independent variables. Multiple comparisons were made using Dunnett's T3 post-hoc test. P values of <0.05 were considered to indicate statistical significance in all tests.
Photopolymerization did not significantly change the microhardness values when compared with no photopolymerization. Microhardness values also showed no significant difference between the three regions in the root canals in both groups.
The mode of polymerization of the cement tested in combination with the translucent quartz fiber post system did not affect the microhardness of the cement at the cervical, middle, or apical regions of the root.

Liver transplantation remains a controversial therapy for Neuroendocrine liver metastases (NLM), with coflicting suvival data reported. The aim was to assess the evolution of outcomes for patients transplanted for NLM in the US, both before and after the introduction of the MELD scoring system in 2002. The UNOS/OPTN database was reviewed to identify patients diagnosed with NLM who subsequently underwent a liver transplantation from 1988 to March 2011 (n = 184); Patient survival was determined using Kaplan-Meier methods and log-rank tests, and cox regression analysis was performed, using SPSS 15.0 (SPSS, Inc, Chicago, IL). The overall NLM patient survivals in the pre-MELD era were 79.5%, 61.4%, and 49.2% at 1, 3, and 5 years, respectively. After the introduction of the MELD score, NET/NLM patients had improved overall patient survivals at 1, 3, and 5 years of 84.7%, 65%, and 57.8%. Patients transplanted after 2002 had an improved survival outcome. Notably, the overall patient survival for NET is not significantly different when compared to the outcomes of patients transplanted for HCC, in the current era. This progress acknowleges the significant improvement in outcomes for NLM patients after liver transplantation and the potential for further gain in the survival of otherwise nonsurgical, terminal patients.
To determine the acceptability of transvaginal ultrasonography (TVU) and associated factors among Nigerian women.
A cross-sectional survey was conducted among 3137 women who presented for transabdominal ultrasound scan between August and November 2010 in two referral hospitals in Nigeria. Data were obtained using a questionnaire. Descriptive and multivariate analysis was performed applying logistic regression analysis; predictors of willingness of participants regarding transvaginal ultrasound were identified using SPSS Statistics (SPSS Inc, Chicago, IL) version 17 software.
The mean age of the women was 33.8 years (standard deviation = 7.9), with 88.8% currently married. About 84% were willing to have TVU, while 54.2% were indifferent about the gender of the sonologist. About 17.3% believed that the procedure is painful. Significant predictors of willingness to have TVU were previous sexual experience and douching, prior painful vaginal examination, and vaginal surgery.
The majority of Nigerian women expressed a willingness to have the TVU procedure without necessarily opting for any gender preference of the operator. Women should be adequately counseled on the operations of the procedure so as to be able to psychologically prepare for them.

The prospective 28 consecutive cataract surgical cases were selected from 85 cataract surgical cases between December 16, 2010 and February 24, 2011. With the same intraocular lens implantation, the predicted spherical equivalent refraction from IOLMaster® (Carl Zeiss AG, Oberkochen, Germany) and ORange Gen II were statistically compared and verified with 1-month postoperative manifest refraction. The data were put into IBM SPSS 19 (SPSS Inc, Chicago, IL) for analysis of variance. Pearson’s correlation coefficient was also calculated to evaluate the correlation between the IOLMaster, ORange Gen II, and 1-month postoperative manifest refraction.
There were no statistically significant differences in the mean spherical equivalent refraction from the IOLMaster, ORange Gen II, and 1-month postoperative manifest refraction (IOLMaster −0.40 diopters, P = 0.07; ORange Gen II −0.43 diopters, P = 0.16; 1-month refraction −0.41 diopters, P = 0.07). Pearson’s correlation study demonstrated that all three were positively correlated (P < 0.05), with the strongest correlation between the ORange Gen II and 1-month postoperative manifest refraction (r = +0.6, P < 0.01).
The ORange Gen II can be considered as an alternative method for intraocular lens selection for cataract patients.

Studies have shown that women's ability to access contraceptive methods depend on their socio-economic, educational, professional status, and the health and well-being of their families and themselves. Therefore, the embarking of the Governments of the Caribbean on important initiatives relating to gynecological matters is very important and timely.
This study aims to examine the perception, attitude and practice of Jamaican women towards the matter of pelvic examination.
Patients and Methods:
The current study used an extracted sample of 7,168 women in their reproductive years (15-49 yrs) from a study which was undertaken by the National Family Planning Board in 2002 on Reproductive Health. Data was analyzed using SPSS for Windows, Version 16.0 (SPSS Inc.; Chicago, Ill. USA). Logistic regression was used to analyze factors/variables pertaining to Pelvic examination.
The findings revealed that older women are more likely to have done a Pelvic examination compared to younger women (χ2 = 675.29, P < 0.001). Age, number of pregnancies that resulted in miscarriages, number of pregnancies that resulted in induced abortion, age of first sexual intercourse, number of years of schooling, area of residence and socio-economic class are statistically significant factors of Pelvic examinations in Jamaica. Therefore, the model had significant predictive power where (χ2 = 1022.79, P < 0.001).
The multidimensional nature of the variables, which emerged in the current study, indicate that a multisectoral approach should be used to address low pelvic and Pap smear examination among Jamaican women.

The aim of this study was to investigate the characteristics and outcomes of treating pulmonary stenosis with percutaneous valvuloplasty, and to compare them among three childhood age groups. All children under 15 years of age who had undergone pulmonary valve balloon valvuloplasty in Madani Heart Center from 2005–2009 were enrolled in this study. Data were analyzed using IBM SPSS software (SPSS, Inc, Chicago, IL). Mean (± standard deviation) age of patients was 55.5 ± 47.4 months. Two-thirds of the subjects had moderate pulmonary valve stenosis. Balloon valvuloplasty failed in nearly one-fifth of the treated patients. There were 17 failures and two cases of mortality, descriptively less frequent among children >5 years; however, the observed difference was not statistically significant. Mild pulmonary valve insufficiency was a common finding.

Despite the fact that Ethiopia has scale up antiretroviral treatment (ART) program, little is known about the patient satisfaction with ART monitoring laboratory services in health facilities. We therefore aimed to assess patient satisfaction with laboratory services at ART clinics in public hospitals.
Hospital based, descriptive cross sectional study was conducted from October to November 2010 among clients attending in nine public hospitals ART clinics in Addis Ababa Ethiopia. Patients’ satisfaction towards laboratory services was assessed using exit interview structured questionnaire. Data were coded and entered using EPI info 2002 (Centers for Disease Control and Prevention Atlanta, GA) and analyzed using SPSS version 15 software (SPSS INC, Chicago, IL, USA).
A total of 406 clients were involved in the study. Of these 255(62.8%) were females. The overall satisfaction rate for ART monitoring laboratory services was (85.5%). Patients were satisfied with measures taken by health care providers to keep confidentiality and ability of the person drawing blood to answer question (98.3% and 96.3% respectively). Moreover, the finding of this study revealed, statistical significant associations between the overall patients’ satisfaction with waiting time to get blood drawing service, availability of ordered laboratory tests and waiting time to get laboratory result with (p < 0.05). Patients receiving blood drawing service less than 30 minute were 7.59 times (95% CI AOR: 3.92–14.70) to be more satisfied with ART monitoring laboratory services compared to those who underwent for more than 30 minutes.
Overall, the satisfaction survey showed, most respondents were satisfied with ART monitoring laboratory services. However, factors such as improving accessibility and availability of latrines should be taken into consideration in order to improve the overall satisfaction.

Patients with Hepatitis C Virus infection are at high risk of getting hepatitis A virus. Hepatitis A virus is an important widespread virus that usually causes more severe medical consequences in patients with chronic liver disease. The purpose of this study was to evaluate prevalence of Hepatitis A Virus antibody in patients with chronic HCV in Isfahan province, Iran.
A cross-sectional study was carried out on 117 patients with chronic hepatitis C virus from spring 2010 to spring 2011. Subject's characteristics such as age, gender, education, genotype of HCV infection and history of intravenous drug use were collected by questionnaire and studied. Statistical analysis was done by SPSS software (version 19.0. 2010, SPSS) using Chi-square test, Fisher Exact tests and Cochran-Armitage trend test.
The mean age of the subjects was 33.18 ± 10.97 years. The seroprevalence of HAV was 94.9% in patients with chronic HCV. The prevalence of anti-HAV increased nearly as age increased. But, there was no statistically significant difference in HAV positive rate according to the age groups (P = 0.242) and other patient's characteristics.
According to the high HAV immunity in our study and less severe form of HAV infection, vaccination was not required in these patients. However, hepatitis A vaccination program should be performed in HAV seronegative patients with HCV to produce an adequate immune response.

To find out from an analysis of empirical data the levels of influence, which a labor union (LU) and Occupational Safety and Health Committee (OSHC) have in reducing the occupational injury and illness rate (OIIR) through their accident prevention activities in manufacturing industries with five or more employees.
The empirical data used in this study are the Occupational Safety and Health Tendency survey data, Occupational Accident Compensation data and labor productivity and sales data for the years 2003 to 2007. By matching these three sources of data, a final data set (n = 280) was developed and analyzed using SPSS version 18 (SPSS Inc., Chicago, IL, USA).
It was found that a workplace with a LU has a lower OIIR than one without a LU. In manufacturing industries with five or more employees in 2007, the OIIR of the workplaces without a LU was 0.87%, while that of workplaces with a LU was much lower at 0.45%. In addition, workplaces with an established OSHC had a lower OIIR than those without an OSHC.
It was found that the OIIR of workplaces with a LU is lower than those without a LU. Moreover, those with the OSHC usually had a lower OIIR than those without. The workplace OIIR may have an impact on management performance because the rate is negatively correlated with labor productivity and sales. In the long run, the OIIR of workplaces will be reduced when workers and employers join forces and recognize that the safety and health activities of the workplace are necessary, not only for securing the health rights of the workers, but also for raising labor productivity.

Central venous catheters (CVC) are associated with mechanical, infectious and thrombotic complications.
To study (a) the incidence of mechanical and infectious complications of CVC insertions and to compare, (b) the rates of these complications between the internal jugular venous (IJV) and the subclavian venous (SCV) accesses.
Settings and Design:
An adult intensive care unit of a tertiary care hospital. Prospective, observational study.
All landmark-based CVC insertions performed between 1st October 2008 and 30th September 2009 were prospectively studied for mechanical and infectious complications.
SPSS software for Windows, Version SPSS 16.0, and Epi Info (3.5.1) software.
Four hundred and eighty central venous catheterizations were studied (IJV route, 241 and SCV route, 239). Mechanical complications occurred in 86 patients (17.9%, bleeding complications-48, catheter-related complications-27 and pneumothorax-11). The IJV route was associated with a significantly higher incidence of bleeding complications (P=0.009). Forty-seven patients had infectious complications (9.79%), like exit site infections (n=17), catheter tip infections (n=22) and catheter-related bloodstream infections (CRBSIs) (n=8). The risks of infectious complications increased significantly if the CVC was in situ for longer than 7 days (P=0.009), especially with IJV cannulae. The incidence density of CVC tip infections was 7.67 per 1000 catheter days and of CRBSIs was 2.79 per 1000 catheter days.
Bleeding complications occurred more frequently with IJV insertions and infectious complications occurred more commonly in cannulae that were left in situ for longer than 7 days.
