Significant association between circumvallate placenta, placental abruption and acute chorioamnionitis in preterm birth: A 23-year retrospective cohort study

AIM

circumvallate placenta, placental abruption and acute chorioamnionitis separately are associated with unfavourable clinical outcomes. We aimed to determine the prevalence and define whether an association exists between the three abnormalities.

METHODS

16,042 placenta pathology reports between 1997 and 2020 from a tertiary care centre in the Netherlands were retrospectively analysed. For the statistical analysis, the chi-square test and bootstrapping were used to evaluate an association.

RESULTS

In our cohort the prevalence of circumvallate placenta is 2.2 %, placental abruption cases 4.0 % and acute chorioamnionitis 20.6 %. We observed a statistically significant association between all three placental abnormalities: circumvallate placenta, placental abruption and acute chorioamnionitis. In addition, there was also an association between circumvallate placenta and acute chorioamnionitis.

CONCLUSION

Our results show that combined presence of circumvallate placenta, placental abruption and acute chorioamnionitis are associated in preterm birth (p = 0.001). A remarkable finding is that the combination of all three abnormalities (circumvallate placenta, placental abruption and acute chorioamnionitis) was not observed in term pregnancies >37 weeks.

Intramyocardial bone marrow cell injection does not lead to functional improvement in patients with chronic ischaemic heart failure without considerable ischaemia

Background

It has been suggested that bone marrow cell injection may have beneficial effects in patients with chronic ischaemic heart disease. However, previous trials have led to discrepant results of cell-based therapy in patients with chronic heart failure. The aim of this study was to evaluate the efficacy of intramyocardial injection of mononuclear bone marrow cells in patients with chronic ischaemic heart failure with limited stress-inducible myocardial ischaemia.

Methods and results

This multicentre, randomised, placebo-controlled trial included 39 patients with no-option chronic ischaemic heart failure with a follow-up of 12 months. A total of 19 patients were randomised to autologous intramyocardial bone marrow cell injection (cell group) and 20 patients received a placebo injection (placebo group). The primary endpoint was the group difference in change of left ventricular ejection fraction, as determined by single-photon emission tomography. On follow-up at 3 and 12 months, change of left ventricular ejection fraction in the cell group was comparable with change in the placebo group (P = 0.47 and P = 0.08, respectively). Also secondary endpoints, including left ventricle volumes, myocardial perfusion, functional and clinical parameters did not significantly change in the cell group as compared to placebo. Neither improvement was demonstrated in a subgroup of patients with stress-inducible ischaemia (P = 0.54 at 3‑month and P = 0.15 at 12-month follow-up).

Conclusion

Intramyocardial bone marrow cell injection does not improve cardiac function, nor functional and clinical parameters in patients with severe chronic ischaemic heart failure with limited stress-inducible ischaemia.

Physical activity in patients with systemic sclerosis

OBJECTIVES

To compare self-reported levels of physical activity (PA) of systemic sclerosis (SSc) patients with the general population. To evaluate in SSc patients factors associated with PA levels and needs and preferences regarding PA.

METHODS

Fifty nine SSc patients completed the Short QUestionnaire to ASsess Health-Enhancing PA. The proportion of patients meeting the Dutch Recommendation for PA (= moderate PA for 30 min on ≥ 5 days/week) and total minutes of PA per week were calculated and compared with similar data from the Dutch population. Characteristics were univariately and multivariately compared between patients with low and high PA levels (either ≤ or > mean minutes/week of the Dutch population). Needs and preferences regarding PA promotion and guidance related to exercise were assessed by questionnaires.

RESULTS

Stratified for age (< 55 or ≥ 55 years) and gender, the proportion SSc patients meeting the Dutch recommendation for PA was not significantly different from the Dutch population. The total minutes of PA per week was significantly lower among SSc patients (1704 vs. 2614, P < 0.001). Multivariable analyses showed that in SSc patients the male gender, scleroderma health assessment questionnaire (SHAQ) and lack of energy were significantly associated with lower PA levels (P = 0.007; P = 0.042; P = 0.025). Two-third of patients required more information about PA.

CONCLUSION

In SSc patients, the total minutes of PA per week are significantly lower compared to the general population. The male gender, functional ability as reflected by SHAQ and lack of energy seem to interfere with PA. These results might guide health professionals in providing their patients with appropriate information on PA.

Developing and validating the Cutaneous WARTS (CWARTS) diagnostic tool: a novel clinical assessment and classification system for cutaneous warts

BACKGROUND

The clinical appearance of cutaneous warts is highly variable and not standardized.

OBJECTIVES

To develop and validate a reproducible clinical tool for the standardized assessment of cutaneous warts to distinguish these lesions accurately.

METHODS

Nine morphological characteristics were defined and validated regarding intra- and interobserver agreement. Based on literature and semistructured interviews, a systematic dichotomous assessment tool, the Cutaneous WARTS (CWARTS) diagnostic tool was developed. The validation consisted of two independent parts performed with photographs from the recent WARTS-2 trial. In part A, the CWARTS diagnostic tool was tested by 28 experienced physicians who assessed photographs of 10 different warts to investigate interobserver concordance. In part B, morphological characteristics were validated by masked and independent scoring of 299 photographs by six different observers. Part B also entailed reassessment of the photographs after at least 1 week. The primary outcome measurement was the intraclass correlation coefficient (ICC).

RESULTS

Presence of black dots (capillary thrombosis) had the greatest ICC (0·85) for interobserver agreement in part A, followed by arrangement (0·65), presence of border erythema (0·64) and sharpness of the border (0·60). In part B, results were similar for interobserver agreement with presence of black dots having the highest ICC (0·68), followed by border erythema (0·64), arrangement (0·58) and colour (0·55). For intraobserver agreement, presence of black dots had the highest agreement (0·70), followed by presence of border erythema (0·694) and colour (0·59).

CONCLUSIONS

Wart phenotype can be reliably assessed using the CWARTS diagnostic tool.

Return to Work 2-5 Years After Stroke: A Cross Sectional Study in a Hospital-Based Population

Purpose To describe factors associated with RTW in patients 2-5 years after stroke. Methods Cross sectional study, including patients 2-5 years after hospitalization for a first-ever stroke, who were <65 years and had been gainfully employed before stroke. Patients completed a set of questionnaires on working status and educational level, physical functioning (Frenchay Activities Index, FAI), mental functioning (Hospital Anxiety and Depression Scale, HADS), Coping Orientations to Problems Experienced, (COPE easy) and quality of life (Short-Form(SF)-36 and EQ(Euroqol)-5D). Caregivers completed the Caregiver Strain Index (CSI). Baseline stroke characteristics were gathered retrospectively. Baseline characteristics and current health status were compared between patients who did and did not RTW by means of logistic regression analysis with odds ratios (OR) and 95 % confidence intervals (CI), adjusted for age and gender. Results Forty-six patients were included, mean age of 47.7 years (SD 9.7), mean time since stroke of 36 months (SD 11.4); 18 (39 %) had RTW. After adjusting for age and gender a shorter length of hospitalization was associated with RTW (OR 0.87; CI 0.77-0.99). Of the current health status, a lower HADS depression score (0.76; 0.63-0.92), a less avoidant coping style (1.99; 0.80-5.00), better scores on the FAI (1.13; 1.03-1.25), the mental component summary score of the SF36 (1.07; 1.01-1.13), the EQ5D (349; 3.33-36687) and the CSI (0.68; 0.50-0.92) were associated with the chance of RTW. Conclusions A minority of working patients RTW after stroke; a shorter duration of the initial hospitalization was associated with a favorable work outcome. The significant association between work status and activities, mental aspects and quality of life underlines the need to develop effective interventions supporting RTW.

Patients who underwent total hip or knee arthroplasty are more physically active than the general Dutch population

Total hip arthroplasty (THA) and total knee arthroplasty (TKA) bring relief of pain and functional disability to patients with end-stage osteoarthritis, and however, the literature on their impact on patients' level of physical activity (PA) is scarce. Cross-sectional study in patients who underwent THA/TKA surgery in the preceding 6-22 months and a random sample of persons aged >40 years from the Dutch general population, participating in a national survey. PA in minutes per week (min/week) and adherence to the Dutch recommendation for PA (NNGB yes/no) were measured by the short questionnaire to assess health-enhancing PA. Multivariable linear (total min/week) and logistic regression analyses (meeting recommendations PA), adjusting for confounders, were performed for THA and TKA separately. In total, 258 THA [62.3% female, aged 69.4 (9.1)] and 221 TKA [65.7% female, aged 69.5 (8.9)] patients and 4373 persons from the Dutch general population [51.4% female, aged 58.9 (11.6)] were included. The presence of THA was associated after adjusting for age, sex, BMI education and musculoskeletal comorbidities, with more total min/week spent on PA (THA 13.8% increase, 95% CI 1.6-27.6%), whilst both TJA groups were associated with adhering to NNGB (THA: OR 1.79, 95% CI 1.26-2.56; TKA: OR 1.73, 95% CI 1.20-2.51). As this study used questionnaires to compare the PA of THA/TKA patients to the general population, some recall and selection bias might have been induced. After surgery, overall, TJA patients are more likely to adhere NNGB than a representative sample of persons >40 years from the Dutch general population.

Less increase of CT-based calcium scores of the coronary arteries : Effect three years after breast-conserving radiotherapy using breath-hold

PURPOSE

The aim of this prospective longitudinal study was to compare coronary artery calcium (CAC) scores determined before the start of whole breast irradiation with those determined 3 years afterwards.

PATIENTS AND METHODS

Changes in CAC scores were analysed in 99 breast cancer patients. Three groups were compared: patients receiving left- and right-sided radiotherapy, and those receiving left-sided radiotherapy with breath-hold. We analysed overall CAC scores and left anterior descending (LAD) and right coronary artery (RCA) CAC scores. Between the three groups, changes of the value of the LAD minus the RCA CAC scores of each individual patient were also compared.

RESULTS

Three years after breath-hold-based whole breast irradiation, a less pronounced increase of CAC scores was noted. Furthermore, LAD minus RCA scores in patients treated for left-sided breast cancer without breath-hold were higher when compared to LAD minus RCA scores of patients with right-sided breast cancers and those with left-sided breast cancer treated with breath-hold.

CONCLUSION

Breath-hold in breast-conserving radiotherapy leads to a less pronounced increase of CT-based CAC scores. Therefore, breath-hold probably prevents the development of radiation-induced coronary artery disease. However, the sample size of this study is limited and the follow-up period relatively short.

Sensitivity-to-change and validity of semi-automatic joint space width measurements in hand osteoarthritis: a follow-up study

OBJECTIVE

To assess sensitivity-to-change and validity of longitudinal quantitative semi-automatic joint space width (JSW) measurements and to compare this method with semi-quantitative joint space narrowing (JSN) scoring in hand osteoarthritis (OA) patients.

DESIGN

Baseline and 2-year follow-up radiographs of 56 hand OA patients (mean age 62 years, 86% women) were used. JSN was scored 0-3 using the Osteoarthritis Research Society International atlas and JSW was quantified in millimetres (mm) in the second to fifth distal, proximal interphalangeal and metacarpal joints (DIPJs, PIPJs, MCPJs). Sensitivity-to-change was evaluated by calculating Standardized Response Means (SRMs). Change in JSW or JSN above the Smallest Detectable Difference (SDD) defined progression on joint level. To assess construct validity, progressed joints were compared by cross-tabulation and by associating baseline ultrasound variables with progression (using generalized estimating equations, adjusting for age and sex).

RESULTS

The JSW method detected statistically significant mean changes over 2.6 years (-0.027 mm (95%CI -0.01; -0.04), -0.024 mm (-0.01; -0.03), -0.021 mm (-0.01; -0.03) for DIPJs, PIPJs, MCPJs, respectively). Sensitivity-to-change was low (SRMs: 0.174, 0.168, 0.211, respectively). 9.1% (121/1336) of joints progressed in JSW, but 3.6% (48/1336) widened. 83 (6.2%) joints progressed in JSW only, 36 (2.7%) in JSN only and 37 (2.8%) in both methods. Progression in JSW showed weaker associations with baseline inflammatory ultrasound features than progression in JSN.

CONCLUSIONS

Assessment of progression in hand OA defined by JSW measurements is possible, but performs less well than progression defined by JSN scoring. Therefore, the value of JSW measurements in hand OA clinical trials remains questionable.

Determinants of return to work 12 months after total hip and knee arthroplasty

Introduction A substantial number of patients undergoing total hip or knee arthroplasty (THA or TKA) do not or only partially return to work. This study aimed to identify differences in determinants of return to work in THA and TKA. Methods We conducted a prospective, observational study of working patients aged <65 years undergoing THA or TKA for osteoarthritis. The primary outcome was full versus partial or no return to work 12 months postoperatively. Factors analysed included preoperative sociodemographic and work characteristics, alongside the Hip Disability and Osteoarthritis Outcome Score (HOOS)/Knee Injury and Osteoarthritis Outcome Score (KOOS), and Oxford Hip and Knee Scores. Results Of 67 THA and 56 TKA patients, 9 (13%) and 10 (19%), respectively, returned partially and 5 (7%) and 6 (11%), respectively, did not return to work 1 year postoperatively. Preoperative factors associated with partial or no return to work in THA patients were self-employment, absence from work and a better HOOS Activities of Daily Living (ADL) subscale score, whereas only work absence was relevant in TKA patients. Type of surgery modified the impact of ADL scores on return to work. Conclusions In both THA and TKA, absence from work affected return to work, whereas self-employment and better preoperative ADL subscale scores were also associated in THA patients. The impact of ADL scores on return to work was modified by type of surgery. These results suggest that strategies aiming to influence modifiable factors should consider THA and TKA separately.

Prediction of single fetal demise after laser therapy for twin-twin transfusion syndrome

OBJECTIVE

Single fetal demise (SFD) occurs in up to 20% of monochorionic pregnancies treated with laser coagulation for twin-twin transfusion syndrome (TTTS). We aimed to determine the independent factors associated with SFD to improve outcome in the care of TTTS pregnancies in the future.

METHODS

This was a case-control study on twin pregnancies treated for TTTS between 2007 and 2013. Data on ultrasound, laser surgery and outcome were retrieved from our monochorionic twin database. We analyzed separately cases of SFD in donor and recipient twins, and compared them with treated pregnancies that resulted in two live births.

RESULTS

Of the 273 TTTS pregnancies treated with laser coagulation, SFD occurred in 30 donors (11.0%) and 27 recipients (9.9%). In 67% of pregnancies with SFD, the death occurred within 1 week after laser treatment. For SFD in donors, absent/reversed end-diastolic flow in the umbilical artery was the strongest predictor (odds ratio (OR), 3.0 (95% CI, 1.1-8.0); P = 0.01), followed by the presence of an arterioarterial anastomosis (OR, 4.2 (95% CI, 1.4-13.1); P = 0.03) and discordance in estimated fetal weight (OR, 1.0 (95% CI, 1.0-1.1); P = 0.04). For SFD in recipients, independent predictors were absent/reversed A-wave in the ductus venosus (OR, 3.6 (95% CI, 1.2-10.5); P = 0.02) and the absence of recipient-to-donor arteriovenous anastomoses (OR, 10.6 (95% CI, 1.8-62.0); P < 0.01).

CONCLUSIONS

Our findings confirm earlier reports that suggest that abnormal blood flow is associated with SFD after laser treatment for TTTS. The association of SFD with the type of anastomoses is a new finding. We speculate that the type of anastomoses present determines the degree of hemodynamic change during laser therapy. Future strategies should aim at stabilizing fetal circulation before laser therapy to decrease the vulnerability to acute preload and afterload changes. Copyright © 2015 ISUOG.

Classifying Back Pain and Peripheral Joint Complaints in Inflammatory Bowel Disease Patients: A Prospective Longitudinal Follow-up Study

BACKGROUND AND AIMS

Peripheral joint complaints [pJTC] and chronic back pain [CBP] are the most common extra-intestinal manifestations in patients with inflammatory bowel disease [IBD]. This prospective study evaluates variables associated with joint/back pain, including IBD disease activity.

METHODS

IBD patients with back pain ≥ 3 months and/or peripheral joint pain/swelling [n = 155], and IBD patients without joint complaints [n = 100; controls], were followed for a period of 1 year. Patients were classified as having SpondyloArthritis [SpA] according to several sets of criteria. Statistical analysis included logistic regression models and linear mixed model analysis.

RESULTS

Of the 155 patients with joint/back pain, 13 had chronic back pain, 80 peripheral joint complaints, and 62 axial and peripheral joint complaints. Smoking, female gender, and IBD disease activity were independently associated with IBD joint/back pain. The Assessment in Spondyloarthritis International Society criteria for axial and peripheral SpA were fulfilled in 12.3% of patients, with 9.7% [n = 15] receiving a rheumatological diagnosis of arthritis. During the 12-month follow-up, the majority of the patients reporting joint/back pain remained stable.

CONCLUSIONS

In our cohort, the majority of IBD patients reported joint/back pain and SpA was relatively common. To facilitate effective care, gastroenterologists should be aware of the various features of SpA to classify joint complaints and, by making use of an efficient referral algorithm, to refer CBP patients to the rheumatologist.

High survival rate of 43% in out-of-hospital cardiac arrest patients in an optimised chain of survival

AIMS

Survival to hospital discharge after out-of-hospital cardiac arrest (OHCA) varies widely. This study describes short-term survival after OHCA in a region with an extensive care path and a follow-up of 1 year.

METHODS

Consecutive patients ≥16 years admitted to the emergency department between April 2011 and December 2012 were included. In July 2014 a follow-up took place. Socio-demographic data, characteristics of the OHCA and interventions were described and associations with survival were determined.

RESULTS

Two hundred forty-two patients were included (73 % male, median age 65 years). In 76 % the cardiac arrest was of cardiac origin and 52 % had a shockable rhythm. In 74 % the cardiac arrest was witnessed, 76 % received bystander cardiopulmonary resuscitation and in 39 % an automatic external defibrillator (AED) was used. Of the 168 hospitalised patients, 144 underwent therapeutic procedures. A total of 105 patients survived until hospital discharge. Younger age, cardiac arrest in public area, witnessed cardiac arrest, cardiac origin with a shockable rhythm, the use of an AED, shorter time until return of spontaneous circulation, Glasgow Coma Scale (GCS) ≥13 during transport and longer length of hospital stay were associated with survival. Of the 105 survivors 72 survived for at least 1 year after cardiac arrest and 6 patients died.

CONCLUSION

A survival rate of 43 % after OHCA is achievable. Witnessed cardiac arrest, cardiac cause of arrest, initial cardiac rhythm and GCS ≥13 were associated with higher survival.

Results from craniocaudal carotid body tumor resection: should it be the standard surgical approach?

OBJECTIVES

To evaluate results after carotid body tumor (CBT) surgery using a novel dissection technique.

METHODS

A retrospective analysis of all operated CBT in the last 6 years was carried out and results were compared with the current literature and our previous series, which reported another 111 cases operated on until 2005.

RESULTS

Forty-five CBTs were removed in 41 (56% hereditary cases) patients (seven Shamblin I, 22 II, and 16 III). There were no cases of permanent cranial nerve injury or stroke. These pre- and postoperative results compare favorably with our previous series and are superior to, generally smaller, studies reported in the contemporary literature.

CONCLUSIONS

This large series of surgically-treated CBTs supports craniocaudal dissection as the surgical technique of choice as it limits blood loss and facilitates safe CBT resection.

Measurement error in the assessment of radiographic progression in rheumatoid arthritis (RA) clinical trials: the smallest detectable change (SDC) revisited

OBJECTIVES

To evaluate if the mean smallest detectable change (SDC) of multiple time intervals using the Bland & Altman (B&A) levels of agreement (LoA) method is an appropriate surrogate for the generalisability analysis method for estimating the overall SDC of radiological progression in rheumatoid arthritis (RA) trials. Secondly, to compare the SDC based on 95% LoA with the SDC based on 80% LoA, and to investigate the association between SDC and baseline damage and progression.

METHODS

Fifteen datasets from randomised controlled trials in RA were scored by 13 experienced readers as pairs according to the modified Sharp/van der Heijde method. The SDC using the 95% and 80% LoA and the generalisability methods was calculated.

RESULTS

21 295 radiographic time points from 7643 patients were included. The mean (range) SDC for the LoA and the generalisability methods was 3.1 (2.3-4.3) and 3.2 (2.3-4.6) units, respectively. The mean ± SD difference between the two methods was -0.13 ± 0.28. The mean SDC including all intervals (n=31) was 3.0 ± 0.7 for 95% LoA and 2.0 ± 0.4 for 80% LoA. No relationship was observed between baseline damage and the SDC, whereas the SDC increased with increasing radiological progression.

CONCLUSIONS

The mean of the interval SDCs obtained by the simple LoA method is a valid surrogate for the SDC obtained by complex generalisability methods. The SDC depends on the level of radiographic progression rather than on the level of absolute damage. In addition, the use of an SDC based on 80% rather than on 95% LoA is proposed.

Electron diffraction study of lipids in non-lesional stratum corneum of atopic eczema patients

Skin barrier impairment is thought to be an important factor in the pathogenesis of atopic eczema (AE). The skin barrier is located in the stratum corneum (SC), consisting of corneocytes embedded in lipids. Ceramides, cholesterol and free fatty acids are the major lipid classes and are crucial for the skin barrier function, but their role in relation to AE is indistinct. Filaggrin is an epidermal barrier protein and common mutations in the filaggrin gene strongly predispose for AE. However, there is no strong evidence that filaggrin mutations are related to the reduced skin barrier in AE. In this study, electron diffraction is used in order to study the lipid organization of control SC and non-lesional SC of AE patients in vivo. An increased presence of the hexagonal lipid organization was observed in non-lesional SC of AE patients, indicating a less dense lipid organization. These changes correlate with a reduced skin barrier function as measured with transepidermal water loss but do not correlate with the presence of filaggrin mutations. These results are indicative for the importance of the lipid organization for a proper skin barrier function.

Adverse childhood experiences of persons at risk for Huntington's disease or BRCA1/2 hereditary breast/ovarian cancer

Huntington's disease (HD) is known to have a negative impact on family life. Offspring of HD patients may be exposed to adversity in childhood because of the parent's disease and its psychological consequences. BRCA1/2 hereditary breast and ovarian cancer (BRCA1/2) increases the risk for offspring of being exposed to parental disease or loss. Childhood adversity is associated with psychopathology and various other problems in later life. Adverse childhood experiences (ACEs) before age 16 were assessed in adults at 50% risk for HD (n = 74) or BRCA1/2 (n = 82) and in controls (n = 101), using the Negative Life Events Scale. Mean number and occurrence of ACEs were compared between groups. The odds of having experienced adversity in childhood were higher in HD offspring and BRCA1/2 offspring than in controls. HD offspring reported a higher mean number of ACEs than controls or BRCA1/2 offspring. In HD offspring, the prevalence of parental disease and parental dysfunction experienced before age 16 was higher than in controls. In BRCA1/2 offspring, the prevalence of parental loss before age 16 was higher than in controls. This study indicates that 53% of HD offspring and 45% of BRCA1/2 offspring are exposed to adversity in childhood or adolescence. The relevance of these findings for counseling in predictive testing programs, reproductive decision-making, and child rearing matters is discussed.

Support for two increased vasopressinergic activities in depression at large and the differential effect of antidepressant treatment

Animal models of depression support a pathogenetic role for vasopressinergic activation involving increased arginine vasopressin (AVP) release and AVP receptor (V1b) synthesis. Evidence of this has been found particularly in patients with highly anxious-retarded (HAR) and above-normal AVP (ANA) depression. A general pathogenetic theory however predicts vasopressinergic activities to play a role in at least all major depressive disorders, and antidepressant (AD) treatment to be mediated by vasopressinergic reduction. We tested these hypotheses by re-analysing the data of 66 depressed patients; 27 with and 39 without AD treatment. The plasma AVP concentration and the AVP-cortisol correlation were used as presumed parameters of AVP release and pituitary V1b receptor function. A high AVP-cortisol correlation (r = 0.72; p < 0.001) was found in the non-AD group, and no correlation in the AD treatment group. AD treatment did not relate to plasma AVP concentration. The AVP-cortisol correlation in HAR and ANA depression was not explained by a low rate of AD treatment. These human data support the hypothesis of increased AVP release and receptor function as pathogenetic characteristics of major depression, and show selective normalization of the AVP-cortisol correlation, which is supposed to reflect the receptor function, by AD treatment.

Reduced cooperativeness and reward-dependence in depression with above-normal plasma vasopressin concentration

The neuropeptide vasopressin is centrally involved in the regulation of social behaviour and response to stress. We previously found support for a subcategory of depression defined by above-normal plasma vasopressin (AVP) concentration. This subcategory is validated by a positive family history of depression and correlating plasma AVP and cortisol concentrations. The data support the validity of above-normal plasma AVP concentration as a genetically determined biological marker for a subcategory of depression. The aim of the present study was to test whether above-normal plasma AVP concentration in depression is related to personality characteristics reflecting a specific social behaviour style. The data of 78 patients from a previously investigated sample were reanalysed. Fifty-eight patients were available after 2 years, 15 of whom with initially above-normal plasma AVP. The dimensions of the Temperament and Character Inventory (TCI) were scored, with particular focus on the dimensions of Cooperativeness (CO) and Reward-dependence (RD). Normative subjects and other depressed subjects were used as controls. After full remission, patients with initially above-normal AVP had low CO compared with normal and patient controls. During depression, these patients had both low CO and low RD compared with normal controls and low RD compared with patient controls. Low CO is a presumably premorbid trait and reduced RD a state-dependent characteristic in depression with above-normal plasma AVP. The low CO further supports the validity of above-normal plasma AVP concentration as a genetically determined biological marker for a subcategory of depression.

Pretreatment insulin-like growth factor-I concentrations predict radiographic osteoarthritis in acromegalic patients with long-term cured disease

OBJECTIVE

The aim of the study was to identify factors influencing the development of osteoarthritis during long-term control of acromegaly, focusing on disease-specific parameters, GH and IGF-I concentrations, and duration of disease, adjusted for the well-known determinants of primary osteoarthritis.

DESIGN

We conducted a follow-up study.

METHODS

We studied 67 patients with adequate biochemical control of acromegaly for a mean of almost 13 yr. Study parameters were the results of radiological assessment of the spine, hip, knee, and hand. Osteoarthritis was defined as radiological osteoarthritis using the scoring system developed by Kellgren and Lawrence. Correlations between potential factors of influence and osteoarthritis were performed by analysis of covariance and adjusted for age, gender, and body mass index.

RESULTS

Patients with pretreatment IGF-I sd scores in the highest tertile had an almost 4-fold increased risk for radiological osteoarthritis of the hip when compared with patients in the lowest tertile. After adjustment for age, gender, BMI, and disease duration, pretreatment IGF-I sd scores predicted radiographic osteoarthritis in all joint sites. Osteoarthritis was not predicted by other factors, including pretreatment GH levels, type of treatment, and duration of follow-up.

CONCLUSION

This is the first study to document pretreatment IGF-I concentration as a predictor of radiographic osteoarthritis in acromegalic patients with long-term disease control.

Computer assisted orthopedic surgery; its influence on prosthesis size in total knee replacement

Improvement of alignment and position of the components in TKAs using Computer Assisted Orthopaedic Surgery (CAOS) has been described. However, much less is known about the accuracy of CAOS in determining the size of the components. The purpose of this study was to evaluate the size of the femoral and tibial component using the CAOS system from Brainlab. The component sizes were compared to pre-operative templating and post-operative scoring the adequateness of size. Forty TKAs (NexGen) were evaluated: 20 using CAOS and 20 conventional. Statistical analysis of the templated and implanted size indicated a fair agreement for the femur (kappa 0.38) and the tibia (kappa 0.35). In the CAOS group significantly more oversizing occurred for the femoral component (p=0.020). No significant difference was found for the tibial component. We conclude there is a risk of oversizing the femoral component of the NexGen system when using CAOS.

A multidisciplinary hand clinic for patients with rheumatic diseases: a pilot study

To describe the characteristics, management strategies and outcomes of patients with rheumatic diseases and complex hand function problems referred to a multidisciplinary hand clinic. Assessments (baseline and after three months of follow-up) included sociodemographic and disease characteristics and various hand function measures. The most frequently mentioned impairments and limitations of the 69 patients enrolled in the study pertained to grip, pain, grip strength, and shaking hands. Fifty-six patients received treatment advice, conservative therapy (n=39), surgery (n=12), or a combination of both (n=5). In 38 of 56 patients (68%) the recommended treatment was performed, and 33 completed the follow-up assessment. On average, patients improved, with an increase in grip strength and the Michigan Hand Outcomes Questionnaire scores reached statistical significance. Two-thirds of patients with rheumatic conditions visiting a multidisciplinary hand clinic reportedly followed the treatment advice (recommendations), with an overall trend toward a beneficial effect on hand function. To further determine the added value of a structured, multidisciplinary approach a controlled comparison with other treatment strategies is needed.

ABO incompatible stem cell transplantation in children does not influence outcome

BACKGROUND

Although delayed red cell engraftment and/or hemolysis have been thoroughly documented in association with ABO incompatibility between donor and recipient in patients undergoing hematopoietic stem cell transplantation (HSCT), there are no studies defining the general, long term clinical outcome in a large group of pediatric patients.

METHODS

We undertook a retrospective single center analysis of children undergoing pediatric allogeneic stem cell transplantation to determine the influence of ABO donor/recipient incompatibility. Outcome was analyzed according to donor type and included survival, graft versus host disease (GvHD), relapse, days of infection, antibiotic use, transfusion requirement and duration of hospital stay.

RESULTS

Two hundred and sixteen children (136 males; 80 females, aged 0-19) transplanted between January 1992 and December 2003 were included in the study. Indications for transplantation were hematological malignancies (n=179) and aplastic conditions (n=37). ABO compatibility was documented in 121 donor/recipient pairs. ABO incompatibility was documented in 95 donor/recipient pairs with 40 major, 40 minor and 15 bi-directional incompatible pairs. ABO incompatibility did not influence survival rate (P=0.3762), the incidence of GvHD (P=0.253) or rate of relapse (P=0.930). Recovery of leucocytes was influenced by ABO incompatibility (P=0.0493), but the rate of infection, transfusion requirements and duration of hospital stay are not.

CONCLUSION

In the pediatric setting, ABO major and/or minor mismatch between donor and recipient did not significantly influence the outcome of HSCT. The choice of donor should be determined by the degree of HLA match and CMV status in preference to ABO blood group compatibility.

The open modified Bankart procedure

We report the outcome of a modified Bankart procedure using suture anchors in 31 patients (31 shoulders) with a mean follow-up of 11 years (10 to 15). The mean age of the patients was 28 years (16 to 39). At follow-up, the mean Rowe score was 90 points (66 to 98) and the Constant score was 96 points (85 to 100). A total of 26 shoulders (84%) had a good or excellent result. The rate of recurrence varied between 6.7% and 9.7% and depended on how recurrence was defined. Two patients had a significant new injury at one and nine years, respectively after operation. The overall rate of instability (including subluxations) varied between 12.9% and 22.6%. All patients returned to work, with 29 (94%) resuming their pre-operative occupation and level of activity. Mild radiological osteoarthritis was seen in nine shoulders (29%) and severe osteoarthritis in one.

We conclude that the open modified Bankart procedure is a reliable surgical technique with good long-term results.

Anxious-retarded depression: relation to two-year outcome of major depressive disorder

BACKGROUND

Anxious-retarded depression is a two-dimensionally defined subcategory of depression derived from DSM-IV melancholia. It is related to increased plasma vasopressin, correlative plasma vasopressin and cortisol levels, and a positive family history. We now explored its relation with outcome.

METHODS

Seventy depressed patients were included to follow-up for two years. Outcome was defined by time until full-remission. Cox regression analyses were used to compare anxious-retarded and non-anxious-retarded patients, as well as melancholic and non-melancholic patients.

RESULTS

Anxious-retarded depression had poor outcome.

LIMITATIONS

The number of patients was relatively small.

CONCLUSION

The poor outcome of anxious-retarded depression further supports its validity.

Implementation of advanced laparoscopy into daily gynecologic practice: Difficulties and solutions

BACKGROUND

The implementation of laparoscopy into Dutch gynecologic practice is slow. This study was conducted to assess the current state of laparoscopy, to identify factors influencing the implementation and to find solutions toward a better implementation.

METHODS

In 2003 a questionnaire was sent to all 151 gynecologists who finished residency within the previous 5 years. The questionnaire addressed practice demographics, performance of laparoscopy, factors influencing use of laparoscopy in practice and means of obtaining laparoscopic skills after residency.

RESULTS

Of 151 gynecologists, 124 (82%) responded, 46 (37%) male and 78 (63%) female. Mean age was 39 years (range 32-47 years). Respondents (73%) believed they were adequately trained during residency for basic laparoscopic procedures, but not for the more advanced procedures (82%). Lack of caseload, lack of being a primary surgeon, and lack of simulator training caused the deficiency of laparoscopic skills at the end of the residency. Causes of the slow implementation were long operating time, lack of attention for laparoscopy during residency, and budgetary problems, but not the financial compensation for gynecologists. In current practice, only 9% believed they reached their preferred level of competence. Hiring an advanced laparoscopic gynecologist was believed to be the best opportunity to reach the preferred level of competence. A minority of respondents supported a referral system or fellowship program.

CONCLUSIONS

Basic laparoscopy is sufficiently mastered during residency training; however, advanced laparoscopy is not. More emphasis should be placed on laparoscopic training of advanced procedures during residency and for gynecologists in practice. Hiring a gynecologist with advanced laparoscopic skills is expected to be the solution for this problem. However, a referral system or fellowship program is not.
