Perioperative surgical outcome of conventional and robot-assisted total laparoscopic hysterectomy.

BACKGROUND: To evaluate surgical outcome in a consecutive series of patients with conventional and robot assisted total laparoscopic hysterectomy. METHODS: A retrospective cohort study was performed among patients with benign and malignant indications for a laparoscopic hysterectomy. Main surgical outcomes were operation room time and skin to skin operating time, complications, conversions, rehospitalisation and reoperation, estimated blood loss and length of hospital stay. RESULTS: A total of 294 patients were evaluated: 123 in the conventional total laparoscopic hysterectomy (TLH) group and 171 in the robot TLH group. After correction for differences in basic demographics with a multivariate linear regression analysis, the skin to skin operating time was a significant 18 minutes shorter in robot assisted TLH compared to conventional TLH (robot assisted TLH 92m, conventional TLH 110m, p0.001). The presence or absence of previous abdominal surgery had a significant influence on the skin to skin operating time as did the body mass index and the weight of the uterus. Complications were not significantly different. The robot TLH group had significantly less blood loss and lower rehospitalisation and reoperation rates. CONCLUSIONS: This study compares conventional TLH with robot assisted TLH and shows shorter operating times, less blood loss and lower rehospitalisation and reoperation rates in the robot TLH group.

[Haemoglobinopathy in the 21st century: incidence, diagnosis and heel prick screening]. / Hemoglobinopathie in de 21e eeuw: incidentie, diagnose en hielprikscreening.

OBJECTIVE: To determine the incidence of severe haemoglobinopathy, to evaluate the effect of heel prick screening, and to identify those children who do not benefit from this early diagnosis. DESIGN: Prospective descriptive study. METHOD: Registration of all symptomatic and asymptomatic children who between 2003-2009 were newly diagnosed with the a severe form of a hereditary disorder concerning the formation of the alpha haemoglobin chain (HbH disease), or the beta haemoglobin chain (sickle cell disease or beta thalassaemia major) in the Netherlands. Registration was done by collecting anonymised reports from the Dutch Paediatric Surveillance Unit and TNO, and by additional questionnaires. RESULTS: During the study period, 48 children (range: 36-76) per year were diagnosed with severe haemoglobinopathy. The overall incidence was 2.5 per 10,000 live births. The incidence of sickle cell disease diagnosed by heel prick screening was 2.1 per 10,000 live births and of thalassaemia major 0.6 per 10,000 live births. In 7% of the children with sickle cell disease who were diagnosed without any form of screening, the diagnosis was made on (a life threatening) infection. Twenty-two percent of the children with a severe form of haemoglobinopathy were not born in the Netherlands. The parents of almost half of the children with sickle cell disease originally came from West- or Central Africa. The parents of children with thalassaemia major were mainly from Morocco or various Asiatic countries. CONCLUSION: The number of children with severe haemoglobinopathy in the Netherlands has trebled since 1992. In order for all children to benefit from early diagnosis and preventive treatment, it is advisable that children who originate from risk areas should be tested for haemoglobinopathy when they first arrive in the Netherlands.

Distribution of extended-spectrum beta-lactamase genes using a commercial DNA micro-array system.

Extended-spectrum beta-lactamase (ESBL) genes are distributed worldwide and their epidemiology is complex. Using the Check-ESBL assay, the distribution of class A ESBL genes in clinical isolates of aerobic Gram-negative bacilli from three laboratories in the East of The Netherlands was determined. Four patient categories were distinguished: (i) patients admitted to an intensive care unit (ICU); (ii) non-ICU inpatients; (iii) outpatients admitted less than a year before collection of the isolate, (<1); (iv) outpatients admitted more than one-year prior to isolate collection or who had never been hospitalized (>1). From February 2009 until March 2010, out of 491 putative ESBL-positive isolates detected by the Vitek2 or Phoenix automated sensitivity testing systems, ESBL genes were detected in 247 (50.3%) by the Check-ESBL assay. Of these, 116 were from hospitalized patients (35 ICU, 81 non-ICU) and 131 were from outpatients (43 <1, 88 >1). In all, 274 ESBL genes were identified in these 247 isolates: 153 CTX-M-1 group (predominantly in E. coli and K. pneumoniae, 70.4% and 51.6% respectively), 67 CTX-M-9 group (predominantly in E. cloacae, 57.9%), 32 SHV, 14 TEM and 8 CTX-M-2 group. ESBL-producing E. cloacae were significantly more common in hospitalized patients than in outpatients, 20.7% and 3.8% respectively (P=0.001). CTX-M-9 group ESBLs were significantly more prevalent in ICU patients (P=0.003), whereas SHV ESBLs were more common in hospitalized patients than in outpatients (P<0.001). There was no significant difference in distribution of ESBL genes between the two outpatient groups.

Conventional surgery and endovenous laser ablation of recurrent varicose veins of the small saphenous vein: a retrospective clinical comparison and assessment of patient satisfaction.

OBJECTIVES: Recurrences of varicosities of the small saphenous vein (SSV) are common. Surgical reintervention is associated with increased complication rates. The aim of the study was to assess the feasibility of endovenous laser ablation (EVLA) in recurrent varicose veins of the SSV and to compare this technique with surgical reintervention. METHODS: All case files of patients treated for SSV varicosities between May 2006 and October 2008 were evaluated and recurrences were selected. Demographics, duplex findings, clinical, aetiological, anatomical and pathological classification, perioperative and follow-up data were all registered. Additionally, a questionnaire focusing on patient satisfaction was taken. RESULTS: Two hundred and eighty-one patients were treated for varicosities of the SSV, of which 42 were for recurrences. Twenty-six of these were treated with EVLA, all under local anaesthesia, and 16 were surgically treated. Most surgically treated patients were treated under regional anaesthesia (88%). Technical success was achieved in 94% of surgically treated patients and in all EVLA-treated patients. Complications in both groups were mostly minor and self-limiting. Sural nerve neuralgia appeared to be more frequent in the surgically treated group (20% versus 9%). After correction for length of follow-up, the incidence of rerecurrences was not statistically significant between groups. CONCLUSION: EVLA is feasible in patients with recurrent varicose veins of the SSV with possibly a lower incidence of sural nerve injury. Patient satisfaction is high for both treatment modalities. Studies with larger samples are indicated to confirm these observations.

Effectiveness of ultrasound screening for developmental dysplasia of the hip.

OBJECTIVE: To determine the effectiveness of ultrasound screening for developmental dysplasia of the hip (DDH) after the neonatal period. DESIGN: Prospective cohort study. SETTING: Child health care centres. PARTICIPANTS: Infants attending the child health care centres. INTERVENTIONS: The intervention group (n = 5170) was screened by ultrasound at 1, 2, and 3 months of age. The control group (n = 2066) was screened by routine physical examination as part of the programme for child health surveillance at the child health care centres (CHC screening). For evaluation of the screening, the children in both the intervention and control group received an ultrasound examination after 6 months of age to detect any abnormality that might have been missed by the screening. RESULTS: The sensitivity of the ultrasound screening was 88.5%, and the referral rate 7.6%. As a result of the ultrasound screening, 4.6% of the children were treated. The sensitivity of the CHC screening was 76.4%, with a referral rate of 19.2%. The treatment rate was 2.7%. Of the treated children in the ultrasound screening group, 67% were referred before the age of 13 weeks, whereas in the CHC screening group only 29% were referred before this age. CONCLUSIONS: This study shows that ultrasound screening detects more children with DDH than CHC screening and that more of them are detected at an earlier age. To accomplish this, even fewer children have to be referred. However, even general ultrasound screening seems not to eradicate late cases of DDH. The higher treatment rate in the population screened by ultrasound may be a result of overtreatment.

Ultrasonographic screening for developmental dysplasia of the hip in infants. Reproducibility of assessments made by radiographers.

We studied the reproducibility of ultrasonographic screening examination of the hip when read by diagnostic radiographers. In order to determine interobserver variability, 200 ultrasonograms were classified according to Graf's method by five observers (four radiographers and one radiologist). The kappa values for interobserver variability indicated moderate agreement (kappa 0.47) for the exact Graf classification and substantial agreement (kappa 0.65) for the classification of normal (type I) versus abnormal (type IIa-IV). Agreement was significantly different for normal, immature and abnormal hips. Comparison of the findings in our interobserver study with existing information based on other examinations and treatment revealed that only a small number of infants with mildly dysplastic hips would have been typed as normal by some observers as a result of observer variability. In conclusion, the interobserver agreement on the ultrasound assessment of the hip was good enough for screening purposes. Observer variability did not result in any severe cases being missed.

Allogeneic bone marrow transplantation with T-cell-depleted marrow grafts for patients with poor-risk relapsed low-grade non-Hodgkin's lymphoma.

We present the clinical results of allogeneic bone marrow transplantation (BMT) with T-cell-depleted grafts from HLA-matched sibling donors in patients with poor-risk relapsed low-grade non-Hodgkin's lymphoma (NHL). Poor risk was defined as relapse within 12 months after or progression during prior treatment. The conditioning regimen consisted of cyclophosphamide and total-body irradiation with or without additional idarubicin. Donor marrow was depleted of T lymphocytes using counterflow centrifugation. Post-BMT prophylaxis of graft-versus-host disease (GvHD) consisted of cyclosporine A. 15 patients with a median age of 47 years (range 30-57) were transplanted. All patients engrafted. After a median follow-up of 36 months (range 9-78), 10 patients were alive and in complete remission (CR). Two of them had relapsed after BMT but re-entered CR following infusions of leucocytes from the original bone marrow donor. Five patients died; causes of death were cardiomyopathy (n = 1), chronic GvHD (n = 1) and infection during chronic GvHD (n = 3). We conclude that allogeneic T-cell-depleted bone marrow transplantation is an efficacious treatment for patients with poor-risk relapsed low-grade NHL. Infusions of donor leucocytes reinduced CR in the two patients with relapse after BMT.
