    Lag screw fixation of dorsal cortical stress fractures of the third metacarpal bone in 116 racehorses

    EQUINE VETERINARY JOURNAL, Issue 7 2010
    S. L. JALIM
    Summary Reasons for performing study: The effectiveness and best method to manage dorsal cortical stress fractures is not clear. This study was performed to evaluate the success of lag screw fixation of such fractures in a population of Thoroughbred racehorses. Hypothesis: Lag screw fixation of dorsal cortical stress fractures is an effective surgical procedure allowing racehorses to return to their preoperative level of performance. Methods: The records of 116 racehorses (103 Thoroughbreds) admitted to Equine Medical Centre, California between 1986 and 2008 were assessed. Information obtained from medical records included subject details, limb(s) affected, fracture configuration, length of screw used in repair and presence of concurrent surgical procedures performed. Racing performance was evaluated relative to these factors using Fisher's exact test and nonparametric methods with a level of significance of P<0.05. Results: Of 92 Thoroughbred horses, 83% raced preoperatively and 83% raced post operatively, with 63% having ,5 starts. There was no statistically significant association between age, gender, limb affected, fracture configuration or presence of concurrent surgery and likelihood of racing post operatively or of having 5 or more starts. The mean earnings per start and the performance index for the 3 races following surgery were lower compared to the 3 races prior to surgery; however, 29 and 45% of horses either improved or did not change their earnings per start and performance index, respectively. Conclusions and potential relevance: Data show that lag screw fixation is successful at restoring ability to race in horses suffering from dorsal cortical stress fractures. [source]


    Association between cognition and daily life functioning in dementia subtypes

    INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 7 2009

    Abstract Objective To investigate the association between cognition and daily life functioning in dementia subtypes. Methods Cross-sectional data were used from 615 patients with dementia who were referred to the Maastricht Memory Clinic of the Maastricht University Medical Centre. Pearson correlation coefficients were calculated between the Mini-Mental State Examination (MMSE; to measure cognitive status) and the Blessed Dementia Scale (BDS; to measure daily life functioning) for the following types of dementia: Alzheimer's Disease (AD, n,=,442); Vascular dementia (VaD, n,=,113); frontotemporal dementia (FTD, n,=,18); Parkinson's dementia (PD, n,=,21); and primary progressive aphasia (PPA, n,=,21). One-way ANOVA was used to test differences in age, MMSE scores and BDS scores across dementia subtypes. Results Scores on the MMSE showed strong correlation with BDS scores in cases of FTD (r,=,,0.80); moderate correlation in cases of AD, VaD, and PD (range r,=,,0.50,0.60); while no correlation was found in PPA cases. Conclusions The association between cognition and daily life functioning varied among dementia subtypes for AD, VaD, FTD and PD. Furthermore, the overall scores on both domains differ between dementia subtypes, indicating that different types of dementia are characterized by a specific pattern of cognitive status and daily life functioning. These findings underline the need for multidomain assessment in patients with dementia. Copyright © 2009 John Wiley & Sons, Ltd. [source]


    Dental enamel defects in children with coeliac disease

    INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 3 2007
    CLAAR D. WIERINK
    Objective., The aim of this study was to investigate whether Dutch children with proven coeliac disease show specific dental enamel defects, and to asses whether children with the same gastrointestinal complaints, but proved no-coeliac disease, lack these specific dental enamel defects. Materials and methods., Eighty-one children (53 coeliac patients and 28 control subjects) were examined during the period 2003,2004 in the Oral Surgery Outpatient Clinic of the Academic Medical Centre in Amsterdam. Result., Twenty-nine (55%) coeliac patients had enamel defects against 5 (18%) control subjects. In the coeliac disease group, the enamel defects were diagnosed as specific in 20 (38%) children, compared with 1 (4%) in the control group. Statistical analysis showed significantly more specific enamel defects in children with coeliac disease than in children in the control group (,2 = 12.62, d.f. = 2, P = 0.002). Conclusion., This study showed significantly more specific enamel defects in Dutch children with coeliac disease as compared with children in the control group. Dentists could play an important role in recognizing patients with coeliac disease. [source]


    Effective program against mother-to-child transmission of HIV at Saint Camille Medical Centre in Burkina Faso

    JOURNAL OF MEDICAL VIROLOGY, Issue 7 2007

    Abstract The present research was aimed to prevent mother-to-child transmission of HIV; to use RT-PCR in order to detect, 6 months after birth, infected children; and to test the antiretroviral resistance of both children and mothers in order to offer them a suitable therapy. At the Saint Camille Medical Centre, 3,127 pregnant women (aged 15,44 years) accepted to be enrolled in the mother-to-child transmission prevention protocol that envisages: (i) Voluntary Counselling and Testing for all the pregnant women; (ii) Antiretroviral therapy for HIV positive pregnant women and for their newborns; (iii) either powdered milk feeding or short breast-feeding and RT-PCR test for their children; (iv) finally, pol gene sequencing and antiretroviral resistance identifications among HIV positive mothers and children. Among the patients, 227/3,127 HIV seropositive women were found: 221/227 HIV-1, 4/227 HIV-2, and 2/227 mixed HIV infections. The RT-PCR test allowed the detection of 3/213 (1.4%) HIV infected children: 0/109 (0%) from mothers under ARV therapy and 3/104 (2.8%) from mothers treated with Nevirapine. All children had recombinant HIV-1 strain (CRF06_CPX) with: minor PR mutations (M36I, K20I) and RT mutations (R211K). Among them, two twins had Non-Nucleoside Reverse Transcriptase Inhibitor mutation (Y18CY). Both mothers acquired a major PR mutation (V8IV), investigated 6 months after a single-dose of Nevirapine. Prevention by single-dose of Nevirapine reduced significantly mother-to-child transmission of HIV, but caused many mutations and resistance to antiretroviral drugs. Based on present study the antiretroviral therapy protocol, together with the artificial-feeding, might represent the ideal strategy to avoid transmission of HIV from mother-to-child. J. Med.

    Reduction of mother-to-child transmission of HIV at Saint Camille Medical Centre in Burkina Faso

    JOURNAL OF MEDICAL VIROLOGY, Issue 2 2006
    J. Simpore
    Abstract One thousand three hundred and twenty-eight pregnant women with less than 32 weeks of amenorrhea received voluntary counseling and testing at Saint Camille Medical Center from May 1, 2002 to December 30, 2004. Following informed consent and pre-test counseling, HIV screening was performed in 1,202 women. According to the prevention protocol, HIV-positive women received a single dose of Nevirapine (200 mg) during their labor, while their newborn received a single dose of Nevirapine (2 mg/kg) within 72 hr from birth. HIV seroprevalence (11.2%) was higher than in the overall population. One hundred and ninty-three children were born at the end of December 2004; 53 children (27.5%) followed a short breastfeeding protocol for 4 months, while 140 (72.5%) were fed artificially. All the children underwent RT-PCR test for HIV 5,6 months after their birth: 173 (89.6%) were HIV negative whilst 20 children (10.4%) were HIV positive. Out of the 20 positive children 5/53 (9.4%) had received breast milk for 4 months, while the remaining 15/140 (10.7%) had been fed artificially (P,=,0.814). Artificially fed babies (3/140 (2.1%)) and 1/53 (1.9%) of those breast fed for 4 months deceased according to mortality rate of HIV-positive children. This shows that there is no statistically significant difference (P,=,0.648) between the mortality of artificially fed (3/140 or 2.1%) and breast-fed (1/53 or 1.9%) children. Artificially fed children (20/140 (14.3%)) and 5/53 (9.4%) of breast-fed children died within 6,10 months. This figure indicates that there is no significant difference between the mortality rate of artificially and that of breast-fed children (P,=,0.427). Although the HIV prevention program reduced significantly the vertical transmission of HIV at Saint Camille Medical Center, the mortality of artificially fed children was still high due to gastrointestinal diseases. The HIV diagnosis by RT-PCR technique was of great help in the early identification of HIV-infected children. J. Med. Virol. 78:148,152, 2006. © 2005 Wiley-Liss, Inc. [source]


    Effect of HIV-1 infection and increasing immunosuppression on menstrual function

    JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 5 2010

    Abstract Aim:, The aim of this study was to determine the prevalence, pattern and determinants of menstrual abnormalities in HIV-positive Nigerian women. Methods:, A cross-sectional study was carried out involving 3473 (2549 HIV-seropositive and 924 seronegative) consecutive and consenting women seen at the HIV treatment centers at the Nigerian Institute of Medical Research, Lagos and the Federal Medical Centre, Markurdi. Results:, The sociodemographic characteristics of the two groups were comparable, except for body mass index (BMI): the HIV-negative women (28.1 ± 8.1) had statistically significantly (P < 0.005) higher BMI compared to the HIV-positive women (21.9 ± 7.5). Menstrual abnormalities were significantly more common in women living with HIV/AIDS (29.1%) compared to the HIV-negative (18.9%) women (P < 0.001). The proportions of women in the two groups with intermenstrual bleeding, menorrhagia, hypermenorrhea, and postcoital bleeding were similar (P > 0.005), however amenorrhea, oligomenorrhea, irregular periods and secondary dysmenorrhea were more common in the HIV-positive women (P < 0.02). Primary dysmenorrhea was less common in HIV-positive women (P < 0.03). Among the HIV-positive women, menstrual dysfunction was more common in women living with HIV/AIDS with opportunistic infections, CD4 count < 200, not undertaking therapy, symptomatic disease and BMI < 20. However, after controlling for cofounders, only CD4 < 200 (odds ratio [OR], 3.65; 95% confidence interval [CI], 1.2,9.7), BMI < 20 (OR, 2.4; 95%CI, 1.3,3.5) and not taking antiretroviral drugs (OR, 2.05; CI, 1.7,6.5) were associated with amenorrhea, oligomenorrhea, irregular periods and secondary dysmenorrhea. Conclusion:, HIV-positive women in this study experienced more menstrual abnormalities of amenorrhea, oligomenorrhea, and irregular periods compared to the HIV-negative controls. HIV-positive women with CD4 count < 200, BMI < 20 and who do not take antiretroviral drugs are at the greatest risk. [source]

    Abstract Aim:, To determine the prevalence of carriers of hepatitis B and C viruses among the obstetrical and gynecological population, the incidence of vertical transmission in obstetrical patients and to ascertain the risk factors associated with their transmission. Methods:, We conducted a prospective study over a 1-year period, from 1 January to 31 December 2005, comprising of an obstetrical population of 5902 deliveries and 548 major gynecology surgery patients. The study population was recruited by simple convenient sampling at Unit-I, Department of Obstetrics and Gynecology, Jinnah Postgraduate Medical Centre, Karachi, Pakistan. Booked obstetrical and major gynecological surgical patients were routinely screened by Enzyme Immunoassay for hepatitis B surface antigen (HbsAg) and anti-hepatitis C antibodies (anti-HCV) on venous blood samples. Liver function and carrier profile tests were performed on mothers who were positive for HBsAg. Babies of mothers with HbsAg were tested at birth for both HbsAg and HbeAg. Results:, Hepatitis B was detected in 275 pregnant women (4.6%) and in 70 (12%) gynecological patients. Hepatitis C was detected in 108 (1.8%) pregnant women and in 89 (16%) gynecological patients. Babies born to mothers with HBV or HCV infections tested negative. Four gynecological patients tested positive for both HBV and HCV infections. Unsafe surgery, injections and inadequately screened blood transfusions were the main underlying causes of infection. Conclusion:, Routine screening of the obstetrical population detected more cases of HBV infection than HCV, whereas HCV was more prevalent in the gynecological population, emphasizing the need for safe medical practices and patient education.

    Does patient feedback improve the consultation skills of general practice trainees?

    MEDICAL EDUCATION, Issue 2 2010
    A controlled trial
    Medical Education 2010:44: 156,164 Context, This study aimed to assess if an additional patient feedback training programme leads to better consultation skills in general practice trainees (GPTs) than regular communication skills training, and whether process measurements (intensity of participation in the programme) predict the effect of the intervention. Methods, We carried out a controlled trial in which two sub-cohorts of GPTs were allocated to an intervention group (n = 23) or a control group (n = 30), respectively. In 2006, allocated first-year GPTs in the VU University Medical Centre attended a patient feedback training programme in addition to the regular communication skills training. The control group attended only regular communication skills training. Trainees were assessed by simulated patients who visited the practices and videotaped the consultations at baseline and after 3 months. The videotapes were randomly assigned to eight trained staff members. The MAAS-Global Instrument (range 0,6) was used to assess (a change in) trainee consultation skills. Results were analysed using a multi-level, linear mixed-model analysis. Results, Data on 50 GPTs were available for the follow-up analysis. Both intervention group and control group GPTs improved their consultation skills: mean MAAS-Global scores for all participants were 3.29 (standard deviation [SD] 0.75) at baseline and 3.54 (SD 0.66) at follow-up (P = 0.047). The improvement in MAAS-Global scores in the intervention group did not differ significantly from the improvement in the control group. The analysis showed a trend for intensity of participation in the patient feedback programme to predict greater improvement in MAAS-Global scores. Discussion, Although the baseline scores were already in the high range, consultation skills in both groups improved significantly. This is reassuring for current teaching methods. The patient feedback programme did not improve consultation skills more than regular communication skills training. However, a subgroup of GPTs who participated intensively in the programme did improve their consultation skills further in comparison with the less motivated subgroup. [source]


    Integrating gender into a basic medical curriculum

    MEDICAL EDUCATION, Issue 11 2005
    P Verdonk
    Introduction, In 1998, gaps were found to exist in the basic medical curriculum of the Radboud University Nijmegen Medical Centre regarding health-related gender differences in terms of biological, psychological and social factors. After screening the curriculum for language, content and context, adjustments aimed at incorporating gender issues were proposed. The aim of this study was to evaluate those adjustments, as well as to investigate whether gender had been successfully incorporated into the basic medical curriculum, and to identify the factors that played a role in this. Methods, The education material of 9 curricular blocks was re-evaluated and interviews were held with block co-ordinators. Results, Since the beginning of the project, gender has increasingly been brought to the attention of the students. Various factors have played a role: concrete and directly executable content-oriented proposals for adjustment; adequate translation of gender differences into actual patient care; motivated block co-ordinators; the presence of a ,trigger person' in the faculty; incorporation into the existing education programme; the involvement of block co-ordinators in decision making, and the provision of practical support. Discussion, Integrating gender into the basic medical curriculum has been largely successful. Block co-ordinators' personal recognition of the importance of gender in patient care greatly facilitated implementation. The evaluation stimulated the forming of new ideas. It is recommended that these factors and those mentioned above should be taken into consideration when integrating gender into other faculties. [source]


    Reporting of adverse drug reactions: predictors of under-reporting in Malaysia,

    PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 2 2007
    Zoriah Aziz PhD
    Abstract Background Malaysia like many other countries worldwide uses spontaneous reporting systems as a mean of collecting data on suspected adverse drug reaction (ADR). However, compared to other countries, which use the system, the reporting rate in Malaysia is very low. Why some physicians do not report ADRs is not well understood. Objective To identify factors, which would predict physicians' failure to send ADR reports. Design and Setting Face-to-face interview using a structured questionnaire involving physicians working at the University of Malaya Medical Centre, Malaysia. Results About a third of the physicians in the Centre participated. Sixty-five of the 415 approached refused to participate. A high proportion of the respondents (81.4%) indicated that they had suspected an ADR but did not report it, while about 40% of the respondents were not aware of the existence of the national reporting system in Malaysia. Logistic regression modelling identified the variable ,ADR considered to be too trivial or too well known to report' as the strongest predictor of not reporting, followed by physicians' category and uncertainty that the reaction had been definitely caused by a drug. Conclusion Important predictor variables, which limit physicians from reporting ADR in Malaysia, were related to uncertainty of types of reaction to report, lack of awareness about the existence, function and purpose of national ADR reporting. The findings could be useful for planning strategies to improve the reporting rate. Copyright © 2006 John Wiley & Sons, Ltd. [source]

    Objective: In southeast Asia, pulmonary tuberculosis (TB) is the most frequently presumed diagnosis for haemoptysis. This study was designed to assess the causes of haemoptysis, the diagnostic yield of causes in different diagnostic modalities and the distribution of older patients. Methods: All patients presenting to the University of Malaya Medical Centre, Kuala Lumpur, Malaysia with haemoptysis were recruited prospectively and evaluated. Results: One hundred and sixty patients were evaluated for haemoptysis; 71 (44.4%) were aged 60 years or more. Significantly more patients smoked in the older age group (P = 0.002). The main causes of haemoptysis in the older patients were bronchogenic carcinoma (49.3%), pneumonia (11.3%), bronchiectasis (8.6%), cryptogenic (5.6%) and active TB (4.2%). Significantly more older patients had carcinoma (P < 0.001), while the younger patients more often had TB (P < 0.001). Chest pain was significantly more common in the older patients (P = 0.025), particularly in patients with carcinoma. Bronchoscopy alone or combined with CT of the thorax was significantly more diagnostic in the older patient (P = 0.006). Conclusion: Bronchogenic carcinoma is the commonest cause of haemoptysis in patients aged 60 years and above. Presumptive anti-TB therapy should not be encouraged despite the regional high prevalence of TB. [source]

    Transjugular intrahepatic portosystemic shunt: an analysis of outcomes

    ANZ JOURNAL OF SURGERY, Issue 10 2009
    Timothy P. Kurmis
    Abstract Background:, Transjugular intrahepatic portosystemic shunts (TIPS) are utilized for the management of complications of portal hypertension, particularly diuretic-resistant ascites and recurrent variceal bleeding. It has also been applied in Budd,Chiari syndrome and hepatorenal syndrome. We report the results in a small series, over 9 years, from a single centre, and compare these to those published in the literature. Methods:, A retrospective case note review of 20 consecutive TIPS procedures performed at Flinders Medical Centre from January 1997 to December 2005 was completed. All indications were included in the analysis. Underlying liver disease, peri-procedure complications, relief of symptoms and patient survival were recorded. Data on type of TIPS, shunt patency and method of follow-up were recorded. Results:, Thirty-six TIPS were performed in 20 subjects. All initial TIPS attempts were successful. Indications were: refractory ascites (18), acute variceal bleeding (12) and hepatorenal syndrome (2). There were no peri-procedure deaths, however. Ninety-day mortality was 20%. Outcomes in model of end-stage liver disease score and biochemical characteristics post-TIPS were comparable to those reported. Overall, TIPS dysfunction rate was 35% at 1 year. TIPS follow-up and patency surveillance was an ad hoc combination of Doppler ultrasound and venography. Conclusion:, TIPS procedure outcomes in our centre are similar to those reported in the literature from large centres. TIPS patency rates may be improved with regular monitoring and early intervention when stenosis occurs. [source]


    Oral cavity squamous cell carcinomas in young patients in a selected Malaysian centre

    ASIA-PACIFIC JOURNAL OF CLINICAL ONCOLOGY, Issue 1 2009

    Abstract Aim: This study aims to evaluate the demographics, to analyze the clinical and pathological findings, treatment and the outcome of oral cavity squamous cell carcinomas (OSCC) in patients aged 40-years old and below in our centre. Methods: Records of patients who were diagnosed with OSCC in the Universiti Kebangsaan Malaysia Medical Centre, Kuala Lumpur, from 1998 to 2003 were analyzed. Their socioeconomic data such as their age, gender and race, risk factors, family history and genetic predisposition were assessed. Other data examined included the sites and stage of the tumor, histopathology results, treatment modality and outcome of OSCC. Results: There were 19 patients with no gender predilection. Malays made up most patients diagnosed with OSCC, followed by Chinese and Indians. There was no significant high-risk habit in this group. Most of the sites involved were the tongue (73.7%), buccal mucosa (15.8%) and alveolus (10.5%). Most of the patients (57.9%) were diagnosed with stage IV disease. Eighteen patients underwent treatment consisting of surgery or radiotherapy or in combination. A 5-year follow up revealed that nine patients (47.3%) survived and remain well, four patients (21.1%) had a recurrence, two patients (10.5%) died of the disease. Conclusion: The majority of patients presented with stage IV disease without any significant high-risk habit. Surgery remains the mainstay of treatment, however, 5-year follow-up showed a less than 50% survival rate. [source]


    Evolution of the complications of laparoscopic hysterectomy after a decade: A follow up of the Monash experience

    Jason J. TAN
    A retrospective review of medical records was performed to assess the incidence and types of significant complications encountered during laparoscopic hysterectomy which would affect the use of a laparoscopic approach versus other routes of hysterectomy. A total of 526 consecutive patients' medical data between January 1994 and August 2007 were reviewed. Two hundred and thirty-two laparoscopic-assisted vaginal hysterectomies and 294 total laparoscopic hysterectomies were performed at Monash Medical Centre, a Melbourne tertiary public hospital, and three Melbourne private hospitals, by or under the supervision of three surgeons. Sixteen significant complications occurred. There were two cases of ureteric fistula, two bladder injuries, two bowel obstructions, four postoperative haematomas, one case of a bladder fistula, four conversions to laparotomy and one superficial epigastric artery injury. Inpatient stay ranged from two to six days. Our complication and inpatient stay rates are consistent with the previously reported rates, although there has been a reduction of incidence of visceral injuries with experience and introduction of new equipment.

    ABSTRACT A retrospective review of medical records was performed to assess the incidence and type of significant complications encountered during laparoscopic hysterectomy. Two hundred and sixty-five consecutive patients were reviewed between the years 1994 and August 2001. Two hundred and thirty-two laparoscopic vaginal hysterectomies and 33 total laparoscopic hysterectomies were performed. The operations were performed at Monash Medical Centre, a Melbourne tertiary public hospital, and two Melbourne private hospitals, by three surgeons. Ten significant complications occurred. There were two cases of ureteric fistula, two bladder injuries, two bowel obstructions, two postoperative haematomas, one case of a bladder fistula and one superficial epigastric artery injury. In-patient stay ranged from two to six days. Our complication and in-patient stay rates are consistent with previously reported rates. [source]


    Team Midwifery Care in a Tertiary Level Obstetric Service: A Randomized Controlled Trial

    BIRTH, Issue 3 2000
    Mary Anne Biró RN
    Background:In 1996 a new model of maternity care characterized by continuity of midwifery care from early pregnancy through to the postpartum period was implemented for women attending Monash Medical Centre, a tertiary level obstetric service, in Melbourne, Australia. The objective of this study was to compare the new model of care with standard maternity care.Methods:In a randomized controlled trial, 1000 women who booked at the antenatal clinic and met the eligibility criteria were randomly allocated to receive continuity of midwifery care (team care) from a group of seven midwives in collaboration with obstetric staff, or care from a variety of midwives and obstetric staff (standard care). The primary outcome measures were procedures in labor, maternal outcomes, neonatal outcomes, and length of hospital stay.Results:Women assigned to the team care group experienced less augmentation of labor, less electronic fetal monitoring, less use of narcotic and epidural analgesia, and fewer episiotomies but more unsutured tears. Team care women stayed in hospital 7 hours less than women in standard care. More babies of standard care mothers were admitted to the special care nurseries for more than 5 days because of preterm birth, and more babies of team care mothers were admitted to the nurseries for more than 5 days with intrauterine growth retardation. No differences occurred in perinatal mortality between the two groups.Conclusions:Continuity of midwifery care was associated with a reduction in medical procedures in labor and a shorter length of stay without compromising maternal and perinatal safety. Continuity of midwifery care is realistically achievable in a tertiary obstetric referral service. [source]


    Thrombocytopenia in hydropic fetuses with parvovirus B19 infection: incidence, treatment and correlation with fetal B19 viral load

    BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 1 2008
    TR De Haan
    Objective, To examine (1) the incidence of fetal thrombocytopenia in hydropic fetuses with congenital B19 virus infection, (2) the effect of intrauterine platelet transfusions and (3) the correlation between fetal B19 viral load and severity of thrombocytopenia. Design, Retrospective analysis of data from prospectively collected fetal blood samples. Setting, Leiden University Medical Centre, the national centre for management of intrauterine fetal disease in the Netherlands. Population, Thirty hydropic fetuses treated with intrauterine red blood cell and platelet transfusions for human B19 virus-induced severe fetal anaemia and thrombocytopenia over a 10-year period. Methods, Fetal blood samples (n= 30) taken before and after intrauterine transfusion were investigated. No cases were excluded, and there was no loss to follow up. Main outcome measures, Parameters recorded were gestational age, experienced fetal movements, gravidity and parity, severity of fetal hydrops, severity of fetal anaemia and thrombocytopenia and megakaryocyte and reticulocyte counts. Survival and procedure-associated complications were documented. Quantitative B19 viral load measurements were performed on all fetal samples. Results, Forty-six percent of all hydropic fetuses showed severe thrombocytopenia. No antenatal intracerebral haemorrhage or procedure-associated bleeding occurred. Overall, survival was 77%. Platelet counts increased following platelet transfusion and decreased significantly following red blood cell transfusion alone. No correlation was found between fetal viral loads and platelet counts. Conclusion, Thrombocytopenia was frequently encountered in fetal B19V infection, but fetal bleeding complications were not noted. Absence of a direct relationship between fetal B19 viral load and platelet counts suggests a temporal dissociation between these findings. Dilutional thrombocytopenia is frequently seen in the fetus following red blood cell transfusion alone. The clinical significance of this phenomenon is unclear. The risk of fluid overload by fetal platelet transfusion in a severely hydropic fetus should be weighed against the low incidence of fetal bleeding complications. [source]


    Assessment of fetal liver volume and umbilical venous volume flow in pregnancies complicated by insulin-dependent diabetes mellitus

    BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 11 2003
    Simona M. Boito
    Objectives To determine fetal liver volume and its relation with umbilical venous volume flow and maternal glycosylated haemoglobin (HbA1c) in pregnancies complicated by diabetes mellitus type I. Design A cross sectional matched control study. Setting Obstetric out patient clinic, Erasmus MC,University Medical Centre, Rotterdam. Population Data from fetuses of diabetic women (n = 32; 18,36 weeks) were compared with data from normal controls (n = 32) matched for gestational age. Methods Umbilical venous cross sectional area (mm2) and time-averaged velocity (mm/s Doppler) were determined for calculation of volume flow (mL/min) and flow per kilogram fetal weight (mL/min/kg). Umbilical artery pulsatility index was determined. Fetal liver volume measurements were obtained using a Voluson 530-D. Main outcome measures Fetal liver volume, umbilical venous volume flow and downstream impedance. Results A statistically significant difference between fetuses of diabetic women and normal controls was found for liver volume (mean [SD]: 45.9 [34.0] vs 38.3 [28.7] mL), abdominal circumference (22.2 [6.6] vs 21.3 [5.6] cm), estimated fetal weight (1162 [898] vs 1049 [765] g) and fetoplacental weight ratio (0.22 vs 0.19) and liver volume/estimated fetal weight ratio (4.13% [0.007] vs 3.62% [0.009]). Umbilical venous volume flow (mL/min) and umbilical artery pulsatility index were not essentially different between the two study groups, but umbilical venous volume flow per kilogram fetal weight was lower (P < 0.05) in the diabetes group (94.3 [26.1] mL/min kg) compared with normal controls (109.5 [28.0] mL/min/kg). A positive correlation existed between fetal liver volume and maternal HbA1c (P = 0.002). Conclusions Measurement of fetal liver volume by three-dimensional ultrasound may play a role in identifying fetal growth acceleration in diabetic pregnancies. Fetal liver volume increase is positively related to maternal HbA1c levels reflecting degree of maternal glycemic control. Fetal liver volume normalised for estimated fetal weight is significantly higher in the fetuses of diabetic women. In the present study, umbilical venous volume flow and fetoplacental downstream impedance are not different between diabetic and normal pregnancies. [source]

    Objectives (1) To calculate the feto-placental volume (FPV), using the haematocrit (Ht) values and the percentages of fetal haemoglobin (HbF), before and after red blood cell transfusion. (2) To estimate the transfusion-induced loss of plasma fluid. Design Retrospective analysis of data of 42 anaemic fetuses at the first transfusion [gestational age (GA) 19,36 weeks]. Setting Department of Obstetrics, Leiden University Medical Centre, The Netherlands. Sample Fifteen hydropic and 27 non-hydropic fetuses. Methods Donor blood volume (Vdonor) and Ht (Htdonor), fetal pre- and post-transfusion Ht values (Htinitial, Htfinal) and percentages of HbF (HbFinitial and HbFfinal) were used to calculate the FPV. The total red cell volume after transfusion (RCVfinal) and Htfinal were used to estimate the plasma fluid loss. Main outcome measures Feto-placental blood volume and loss of plasma fluid. Results The equations that use Htfinal over-estimate the FPV when the formula does not account for the difference between donor and post-transfusion Ht (FPVHt= 21.36 * GA , 390; r= 0.89). FPV is under-estimated (FPVHt= 9.90 * GA , 172; r= 0.84) when the blood volume increases with a volume less than the added donor blood volume. The calculation of FPV, using HbF percentages and the initial fetal RCV, is independent of volume changes (FPVHbF= 15.10 * GA , 279; r= 0.85). Comparing RCVfinal and Htfinal values showed that 31.1 ± 14.5% of the transfused volume was lost. Results of the hydropic fetuses did not differ from those of the non-hydropic fetuses. Conclusions FPV values based on Ht values are less reliable than those based on RCV and HbF findings. When, for practical reasons, Ht values have to be used, we propose an adapted equation for the calculation of the necessary volume of donor blood: Vdonor= FPVHbF* (Htfinal, Htinitial) / (Htdonor, 0.70 * Htfinal).

    Objective To measure activin A content and to localise and semi-quantitate activin receptors in human myometrium at term and during labour. Design Myometrium was collected from non-pregnant women (n= 6), pregnant women at term not in labour (n= 6) and at term in labour (n= 6). Setting Monash Medical Centre, Melbourne, Australia. Main outcome measures Tissue lysates of myometrium were analysed for activin A content using an enzyme-linked immunosorbent assay and activin receptor proteins IA, IIA and IIB using Western hybridisation. Activin ,A -subunit and activin receptors were localised in myometrium by immunohistochemistry. Results Activin A was detected by ELISA in non-pregnant, pregnant and labouring myometrium. Levels were significantly higher in labouring myometrium. The three activin receptors IA, IIA and IIB were detected in all myometrial samples by Western hybridisation. Receptor IA was expressed in significantly higher levels in pregnant myometrium. Receptor IIA was very weakly expressed throughout. The expression of receptor IIB was similar in all three groups. Activin ,A -subunit and all three receptors were localised to the endothelial cells of myometrial blood vessels. Neither activin ,A -subunit nor any of the three activin receptors were immunolocalised to myometrial smooth muscle cells in the three groups. This result was confirmed by Western blotting for expression of activin receptors in isolated myometrial smooth muscle and microvascular endothelial cells. Conclusion The myometrium is not a target for activin A during late pregnancy or labour. However, activin A may have a role in the regulation of microvascular endothelial cell function in the myometrium. [source]


    Ultrasonographic measurement of endometrial changes following discontinuation of tamoxifen treatment in postmenopausal breast cancer patients

    Ilan Cohen MD
    Objective To assess whether there is a decrease in endometrial thickness following discontinuation of tamoxifen treatment as measured by ultrasound. Design Prospective study. Setting Department of Obstetrics and Gynaecology, Sapir Medical Centre, Kfar-Saba, Israel. Population Fifty-eight postmenopausal women with breast cancer who were treated with tamoxifen. Methods Transvaginal ultrasonographic measurements of endometrial thickness. Main outcome measures Evaluation of the changes of endometrial thickness and the frequency the endometrium reached a thickness of , 5 mm at different time intervals after stopping tamoxifen treatment. Results There was a significant decrease in median thickness of the endometrium, within six months after stopping tamoxifen, from 7.75 mm measured at the last ultrasonographic study performed before tamoxifen discontinuation down to 5.2 mm (P= 0.002). There were no further reductions in endometrial thickness, and it remained constantly low in subsequent ultrasonographic studies which were performed at various times up to 30 months following the discontinuation of tamoxifen treatment. While taking tamoxifen, only 25.9% of the women had an endometrial thickness of , 5 mm. This proportion doubled in their first six months after stopping. Conclusions Median thickness of endometrial thickness significantly reduced within six months following tamoxifen discontinuation, and remained constantly low thereafter. This finding may support use of ultrasonographic imaging for the measurement of tamoxifen's effect on the endometrium of postmenopausal breast cancer patients. [source]


    Implementation of a short-stay programme after breast cancer surgery,

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 2 2010
    M. de Kok
    Background: Short-stay breast cancer surgery (24 h or day case) is not common practice in Europe. This before,after comparative study was carried out to test the feasibility of systematically implementing a care programme incorporating short-stay admission using strategies tailored to individual hospital needs, and to assess safety and facilitating factors. Methods: Patients with breast cancer from four Dutch hospitals participated. The intervention concerned the programme developed by the Maastricht University Medical Centre. This was implemented through local multidisciplinary meetings and educational outreach visits. Results: Of 421 eligible patients, 324 (77·0 per cent) gave consent to participate. The proportion of patients who had short-stay treatment increased from 45·3 per cent before to 82·2 per cent after implementation of the programme (P < 0·001). No increase was observed in the rate of complications, readmissions, reoperations or number of visits to the emergency department. Factors associated with an increased chance of short-stay treatment were: breast-conserving surgery, having children and being employed. Being aged over 64 years showed a trend towards a decreased chance. Conclusion: Introducing a care programme incorporating short stay following breast cancer surgery in four hospitals was feasible and safe. Copyright © 2010 British Journal of Surgery Society Ltd.

    CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 5 2010
    Adam K Rudkin BMBS
    Abstract Background:, To investigate the visual outcomes in acute central retinal artery occlusion (CRAO) with current standard therapy at two university teaching hospitals. Methods:, Retrospective analysis of two cohorts of CRAO patients from John Hopkins Hospital (JHH; USA), and Flinders Medical Centre (FMC; Australia), treated with current standard therapy. The outcome measures were visual acuity, and subsequent ocular and systemic ischaemic events. Results:, The mean follow-up period was 11.2 ± 13.1 months in the JHH cohort and 35.4 ± 34.9 months in the FMC cohort. The frequency distribution of vascular risk factors and the incidence of subsequent ischaemic events were similar for the patients from both institutions. All patients from JHH were treated as inpatients, whereas 79% of patients from FMC were treated as outpatients. More patients in the JHH cohort underwent paracentesis, ocular massage or were treated with intraocular hypotensive agents (76%) than in the FMC cohort (26%); however, there was no significant difference in visual outcome between the two cohorts (P = 0.114). Conclusion:, Despite differences in management of CRAO between two institutions in different countries, visual outcomes were similar. This suggests a lack of efficacy of current standard treatment in acute CRAO. [source]


    Temporal endosonographic evaluation of anal sphincter integrity after primary repair for obstetric ruptures: a case for specific training of obstetricians

    COLORECTAL DISEASE, Issue 7Online 2010
    P. Pronk
    Abstract Objective, To evaluate primary repaired obstetric lesions of the anal sphincter complex on anal endo-ultrasound within a few days and 8 weeks after primary repair and to investigate in this way the influence of suboptimal woundhealing on the final anatomical result. Furthermore to investigate the relation between faecal incontinence and sphincter defects. Design, A prospective cohort study. Setting, The obstetric clinic and coloproctology outpatient clinic of the Zaans Medical Centre in Zaandam, the Netherlands. Subjects, A cohort of 32 consecutive women with primary surgically repaired 3B, 3C or 4th degree anal sphincter defect after vaginal delivery. Main outcome measures, Appearance of the anal sphincter complex on anal endo-ultrasound within a few days week and 8 weeks after primary surgical repair, i.e. first and second ultrasound, respectively. Evaluation of anal continence, using the Vaizey incontinence score, at second ultrasound. Results, No major wound breakdown was seen and four women had superficial, skin related wound problems. Twenty-eight women (87.5%) had a repaired external anal sphincter on the first and the second ultrasound. Of four external anal sphincter defects on first ultrasound one defect was not present on second ultrasound. The internal sphincter showed a defect on first ultrasound in 11 women and this was still present in 10 on second ultrasound. A total of 11 women had a persisting anal sphincter defect (external, internal or in combination). Mean Vaizey scores were significantly higher in women with a persisting sphincter defect (EAS, IAS or in combination) than in women with no sphincter defects, 2.3 and 0.4 respectively (95% CI 0.1,3.6, P = 0.04). Conclusion, Anal endo-ultrasound may be used for early evaluation of surgical repair of anal sphincter lesions after vaginal delivery. Persisting defects in the anal sphincters, in this series not because of major wound breakdown, can be explained by inadequate surgical repair. [source]

    Objective, To evaluate the relationship between single nucleotide polymorphisms (SNPs) in the HER-2 gene, body mass index (BMI) and the risk of endometrial cancer. Design, Case,control study. Setting, Medical centres in Korea. Sample, DNA samples and medical histories were obtained from 125 endometrial cancer cases and 302 controls. Methods, The genotypes evaluated in HER-2 at positions ,423, ,655, ,776, ,857, ,1170, ,1177, ,1253 of the coding region and two SNPs located in an intron by SNP-IT assay using SNPstream Ultra,high throughput system. Main outcome measures, Odd ratio for endometrial cancer associated with HER-2 polymorphisms and BMI. Results, Cases had a significantly higher BMI than controls and the obese subjects had a 2.65-fold increased risk for endometrial cancer. However, HER-2 polymorphism was not associated significantly with the risk of endometrial cancer. Subjects with BMI , 25 kg/m2 who carried rs1801200 AA, rs1801200 GA/GG, rs1810132 CT/CC, rs2517951 CT/TT and rs1058808 CG/GG genotype had significantly increased risk of endometrial cancer than subjects with a normal BMI (P for linear trend <0.05). However, the risk in the subjects with the variant allele for HER-2 genotypes did not differ significantly compared to those with homozygous wild-type allele within specific BMI subgroups. Conclusions, Endometrial cancer risk increased significantly in proportion to BMI. However, HER-2 polymorphism did not affect significantly on the risk of endometrial cancer. [source]


    Continuous factor VIII infusion therapy in patients with haemophilia A undergoing surgical procedures with plasma-derived or recombinant factor VIII concentrates

    HAEMOPHILIA, Issue 5 2002
    D. Dingli
    Summary., We describe the experience of a single medical centre with continuous factor VIII (FVIII) infusion therapy in a cohort of patients undergoing elective surgery. Twenty-eight patients had a total of 45 procedures. Intraoperative haemostasis was considered excellent in all 45 cases. FVIII levels were maintained between 46% and 191% of normal (median, 103%) for 2,7 days. Bleeding occurred after five procedures (11%) at times when factor VIII levels were within haemostatic range. No patient required reoperation to control bleeding. There were no cases of sepsis related to continuous infusion of factor VIII. We conclude that continuous infusion: (1) is a safe and effective means of replacement therapy in patients with haemophilia undergoing surgery; (2) provides easier monitoring and more constant coagulation factor levels; and (3) has the potential to decrease the cost of replacement therapy by reducing overall usage of product.

    An exploratory study of resilience and job satisfaction among psychiatric nurses working in inpatient units

    INTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 5 2010
    Patricia S. Matos
    ABSTRACT The present exploratory study was designed to examine the relationship between resilience and job satisfaction in psychiatric nurses working in inpatient units in a large, urban medical centre. The long range goal was to understand the dimensions of job satisfaction in this inpatient environment in order to implement nurse retention programmes specifically targeted toward teaching nurses skills in developing resilience. The nurses (n = 32) reported a high level of resilience and high job satisfaction. The job satisfaction subscale of professional status had the highest mean rating among these nurses, and the physician,nurse interaction subscale had the lowest mean score. Implications for future practice and research are addressed. [source]

    chen c.c.-h., chang y.-c., huang g.-h., peng j.-h. & tseng c.-n. (2010) Persistent cognitive decline in older hospitalized patients in Taiwan. Journal of Advanced Nursing,66(9), 1991,2001. Abstract Aim., This paper is a report of a study conducted to determine the prevalence and predictors of persistent and transient cognitive decline in older hospitalized patients over 6 months after hospital discharge. Background., Cognitive decline occurs in 16,35·5% of older hospitalized patients, but this decline may be persistent rather than transient. Distinguishing persistent from transient cognitive decline is clinically useful. Methods., For this prospective cohort study, 291 older patients were recruited from five medical and surgical units at a tertiary medical centre in Taiwan between 2004 and 2006. Participants were assessed for cognitive status by scores on the Mini-Mental State Examination at admission, discharge, 3 and 6 months postdischarge. Persistent cognitive decline was defined as continuing score reduction and ,3-point reduction 6 months postdischarge. Transient decline was defined as ,3-point reduction at some stage, with a total decline <3 points 6 months postdischarge. Findings., The cognitive status of the majority of participants (57·4%, n = 167) decreased ,3 points during follow-up. Of these decliners, 59 (35·3%) had persistent cognitive decline, with an average 5·32-point reduction 6 months postdischarge. Forty-six (27·5%) participants experienced transient cognitive decline. After multiple adjustments in logistic regression analysis, persistent decline was predicted by no in-hospital functional decline (OR = 0·16, P = 0·002), more re-admissions after discharge (OR = 2·42, P = 0·020), and older age (OR = 1·09, P = 0·048). Conclusion., A new perspective is needed on discharge planning on patients at risk for persistent cognitive decline. Nurses can oversee the delivery of care, identify cognitive decline, refer patients, and educate families on strategies to enhance cognitive functioning for their aging relatives. [source]


    Patients' perceptions of nursing care in the hospital setting

    JOURNAL OF ADVANCED NURSING, Issue 4 2003
    Lee A. Schmidt PhD RN
    Background., Patient satisfaction and patient satisfaction with nursing care data are routinely collected as an indicator of the quality of services delivered. Despite the widespread collection and reporting of these data, the theoretical basis of patient satisfaction and patient satisfaction with nursing care remains unclear. Without a clear theoretical base, interpretation of patient satisfaction findings is hampered and the entire line of patient satisfaction research is of questionable validity. It has been suggested that, to understand patient satisfaction, patient perceptions of their care must first be understood. Aim., The aim of this study was to discover patients' perceptions of the nursing care they receive in the hospital setting. Method., Grounded theory method was used in this study of eight medical,surgical patients recently discharged from an academic medical centre in the south-eastern United States of America (USA). Participants were interviewed and the verbatim transcripts analysed using the constant comparative method. Findings., Four categories of patient perceptions of their nursing care emerged from the data. ,Seeing the individual patient' captures the unique nature of the nursing care experience for each patient. ,Explaining' represents the informal explanations given by nursing staff as they provide care. ,Responding' refers to both the character and timeliness of nursing staff's responses to patient requests or symptoms. ,Watching over' represents the surveillance activities of nursing staff. Conclusions., The categories identified in this study may be used in efforts to further develop a formal theory of patient satisfaction with nursing care. These categories should also be tested with patients possessing a wider range of characteristics, to assess the transferability of the findings. [source]
