Pelvic floor muscle strength and thickness in continent and incontinent nulliparous pregnant women

The aim of the study was to measure pelvic floor muscle function in continent and incontinent nulliparous pregnant women. The study group consisted of 103 nulliparous pregnant women at 20 weeks of pregnancy. Women reporting urinary incontinence once per week or more during the previous month were classified as incontinent. Function was measured by vaginal squeeze pressure (muscle strength) and increment in thickness of the superficial pelvic floor muscles (urogenital diaphragm) assessed by perineal ultrasound. Seventy-one women were classified as continent and 32 women as incontinent. Continent women had statistically significantly higher maximal vaginal squeeze pressure and increment in muscle thickness when compared with incontinent women. There was a strong correlation between measurements of vaginal squeeze pressure and perineal ultrasound measurements of increment in muscle thickness. This study demonstrates statistically significant differences in pelvic floor muscle function measured by strength and thickness in continent compared with incontinent nulliparous pregnant women. Editorial Comment: This study evaluated pelvic floor muscle function in 103 nulliparous continent and incontinent women at 18–20 weeks gestation. Pelvic floor muscle strength was assessed by measuring vaginal squeeze pressure, and thickness of the urogenital diaphragm during both relaxation and contraction was measured using perineal ultrasound. The authors found a statistically significant higher vaginal squeeze pressure and higher mean increment in muscle thickness in the continent compared with incontinent group as well as a strong correlation between pelvic floor muscle strength and increment in thickness. Although describing several benefits of ultrasonography in assessing pelvic floor muscles, the authors did acknowledge the difficulty in identifying and measuring these muscles, and the learning curve involved with perineal ultrasound. Another limitation was the subjective classification of continence status based on self-reported symptoms. The implication of low pelvic floor muscle strength and thickness as risk factors for the development of urinary incontinence is beyond the scope of this study.     

Suicidal Behavior After Severe Trauma. Part 2: The Association Between Methods of Torture and of Suicidal Ideation in Posttraumatic Stress Disotrder

The study reports on 65 refugees with diagnoses of posttraumatic stress disorder (PTSD) and manifest suicidal behavior (40% had suicide attempts; 29% detailed suicide plan; 31% recurrent suicidal thoughts). Our hypothesis was that the predominant kind of stressful experience in PTSD patients might be reflected in their choice of method when pondering or attempting suicide. Relationships were found to exist between the main stressors and the respective subjects' preference for suicide method. Particularly among PTSD patients with a history of torture, an association was found between the torture methods that the victim had been exposed to, and the suicide method used in ideation or attempts. Blunt force applied to the head and body was associated with jumping from a height or in front of trains, water torture with drowning, or sharp force torture with methods involving self-inflicted stabbing or cutting. Relationships between main stressors and content of suicidal ideation are discussed.     

Thromboembolic complications after arthroscopic knee surgery: Incidence and risk factors in 101 patients

Deep venous thrombosis (DVT) and pulmonary embolism (PE) are less common after knee arthroscopy than after elective hip and knee arthroplasties. There is no consensus on the optimal prophylaxis. In this prospective cohort study, we used ultrasound, phlebography and lung scan pre-and postoperatively to assess the incidence of thromboembolic complications in 101 consecutive patients who underwent knee arthroscopy. Preoperatively, patients were screened for typical risk factors for DVT such as age, obesity, varicose veins, contraceptive pills and nicotine abuse. All patients received a once-daily injection of 5000 IU of low molecular weight heparin, at least 12 hours prior to surgery.

5 weeks after surgery, the same screening tests were repeated. In 12 of the 101 patients either DVT or PE was diagnosed. DVT occurred in 8 cases, 4 of which were silent and 4 symptomatic. The number of PEs was 9, 8 silent and 1 symptomatic. We found no correlation between DVT or PE and individual clinical risk factors, but there was a tendency towards the development of DVT and PE, with a higher number of risk factors. We found no correlation between DVT and intraoperative risk factors such as use of a tourniquet, type of anesthesia or duration of surgery. The relatively high rate of thromboembolic events after knee arthroscopy in our study suggests the need of all patients for routine use of thromboprophylaxis, probably in a higher dose than given.     

Cosmetic results after wire-guided biopsy of benign breast lesions

Background: There are surprisingly few reports about the cosmetic results of wire-guided biopsy of benign breast lesions as opposed to breast-conserving surgery and irradiation of early breast cancer (BCT).

Study Design: Twenty potential perioperative risk factors for adverse cosmetic results after wire-guided breast biopsy were prospectively evaluated in 101 patients undergoing the first single biopsy after suspicion of a malignant lesion that subsequently proved to be benign. The overall cosmetic result was evaluated by using 6 specific cosmetic indices individually scored 6 months after the breast biopsy.

Results: The overall cosmesis was excellent, good, fair, or poor in 48.5%, 26.7%, 12.9%, and 11.9% of cases, respectively. The corresponding figures according to appraisal by the patients were 22.8%, 58.4%, 17.8%, and 1.0%, respectively. Unsatisfactory (fair or poor) overall cosmetic results were related to excisions extending down to the fascia (p = 0.001) and postoperative complications (p = 0.018) in multivariate analysis. Notably, specimen volume had no significant impact on overall cosmesis, as opposed to cosmesis after BCT.

Conclusions: Cosmetic outcomes after wire-guided biopsy of benign breast lesions were excellent or good in at least 75% of cases. Excisions extending down to the pectoralis fascia and complications were associated with poor aesthetic outcomes.     

Percutaneous revascularization in acute myocardial infarction due to left main stem occlusion

Following the encouraging results of trials testing the effect of primary percutaneous coronary intervention (PCI) more cases of left main arterial stenosis (LMS) as culprit lesions in acute myocardial infarction (AMI) are being handled. Not many cases of primary PCI on LMS have been published. We present 12 cases of primary PCI on LMS. Eighty-three percent of the patients presented with cardiogenic shock and only 42% were discharged alive. Due to the high rate of cardiogenic shock at presentation, PCI seems to be the treatment of choice, over coronary artery bypass grafting (CABG), although one might consider using PCI as a bridge over to CABG.     

Long-term outcome after mitral valve repair

BACKGROUND: Several studies reported excellent long-term results after mitral valve repair for regurgitation, however a number of patients still experience recurrent mitral valve regurgitation which requires reoperation. We have evaluated the long-term outcome of a consecutive series of patients who underwent mitral valve repair for regurgitation in an attempt to identify the risk factors associated with late failures. PATIENTS AND METHODS: One-hundred and sixty-four patients underwent mitral valve repair for ischemic and degenerative mitral valve regurgitation. Seventy-two patients underwent echocardiographic evaluation a median of 5.6 years after surgery. RESULTS: Ten-year survival freedom from any fatal cardiac event was 75.9% and survival freedom from redo mitral valve surgery was 93.8%. Multivariable analysis showed that residual mitral valve regurgitation grade>1 as assessed during the immediate postoperative period (at 10-year, 60.6% vs. 95.7%, p=0.001, RR 20.7, 95%C.I. 3.4-125.3) and chronic obstructive pulmonary disease/asthma (at 10-year 66.8% vs. 95.2%, p=0.013, RR 12.0, 95%C.I. 1.7-85.2) were predictors of redo mitral valve surgery. The same findings were observed also among patients with myxomatous degenerative disease. At echocardiographic follow-up, no significant improvement was detected in terms of left ventricular ejection fraction, whilst mitral valve regurgitation grade (median, 3 to 1), New York Heart Association class (median, 2 to 1) and left atrium diameter (median, 50 to 44 mm) decreased significantly. CONCLUSIONS: This study confirms the excellent clinical long-term results after mitral valve repair. An adequate repair technique is advocated in order to decrease the immediate postoperative rate of residual regurgitation>1 as this is a main determinant of late failures requiring redo mitral valve surgery. Further studies are required to better define the possible causative role of chronic obstructive pulmonary disease and any underlying connective tissue metabolic disorder in late failures after mitral valve repair.     

Transabdominal ultrasound measurement of pelvic floor muscle activity when activated directly or via a transversus abdominis muscle contraction

AIMS: The purpose of the present study was to compare the effectiveness of instruction to contract the pelvic floor muscles (PFM), the transversus abdominis (TrA), and the TrA + PFM visualized as displacement of the pelvic floor by ultrasound. MATERIALS AND METHODS: Twenty female physical therapists, mean age 41.1 years (range 26-56) participated in the study. A 3.5 MHz 35 mm curved linear array ultrasound transducer (Dornier Medtech) was placed in the mid-sagittal plane immediately suprapubically, angled at 15-30 degrees from the vertical depending on subcutaneous fat and anatomical variations, to image the pelvic floor. Six trials of three maneuvers in random order were performed: contraction of PFM, TrA, and TrA + PFM. RESULTS: In spite of correct contractions assessed by palpation and clinical observation, one subject demonstrated a downward movement of the pelvic floor during PFM contraction on ultrasound. Six subjects (30%) showed a downward movement during a TrA- contraction, and two during the combined TrA + PFM contraction. Instruction to contract PFM produced significantly greater mean displacement: 11.2 mm (95% CI 7.2-15.3) than TrA 4.3 mm (95% CI -0.2-8.8), P < 0.01, and combination: 8.5 mm (95% CI 5.2-12), P = 0.04. Hence, instruction of PFM contraction produced a 61.6% greater displacement of the pelvic floor in the correct direction than a TrA contraction. CONCLUSIONS: It is concluded that ultrasound is a more valid method than palpation and clinical observation to assess PFM function, and that instruction to contract the PFM produces a significantly more effective pelvic floor muscle contraction than instruction to perform a TrA contraction.     

Postoperative Cognitive Dysfunction in Middle-aged Patients

Background: Postoperative cognitive dysfunction (POCD) after noncardiac surgery is strongly associated with increasing age in elderly patients; middle-aged patients (aged 40-60 yr) may be expected to have a lower incidence, although subjective complaints are frequent.

Methods: The authors compared the changes in neuropsychological test results at 1 week and 3 months in patients aged 40-60 yr, using a battery of neuropsychological tests, with those of age-matched control subjects using Z-score analysis. They assessed risk factors and associations of POCD with measures of subjective cognitive function, depression, and activities of daily living.

Results: At 7 days, cognitive dysfunction as defined was present in 19.2% (confidence interval [CI], 15.7-23.1) of the patients and in 4.0% (CI, 1.6-8.0) of control subjects (P < 0.001). After 3 months, the incidence was 6.2% (CI, 4.1-8.9) in patients and 4.1% (CI, 1.7-8.4) in control subjects (not significant). POCD at 7 days was associated with supplementary epidural analgesia and reported avoidance of alcohol consumption. At 3 months, 29% of patients had subjective symptoms of POCD, and this finding was associated with depression. Early POCD was associated with reports of lower activity scores at 3 months.     

Risk-scoring Method for Prediction of 30-Day Postoperative Outcome after Infrainguinal Surgical Revascularization for Critical Lower-limb Ischemia: a Finnvasc Registry Study

Background The aim of the present study was to develop a risk-scoring method for prediction of immediate postoperative outcome after infrainguinal surgical revascularization for critical limb ischemia. Methods The Finnvasc registry included data on 3,925 infrainguinal surgical revascularization procedures. This database was randomly divided into a derivation and a validation data set of similar sizes. Results In the overall series, 30-day postoperative mortality and major amputation rates were 3.1% and 6.3%, respectively. The 30-day postoperative mortality and/or limb-loss rate was 9.2%. Diabetes, coronary artery disease, foot gangrene, and urgent operation were independent predictors of 30-day postoperative mortality and/or major lower-limb amputation. A risk score was developed by assigning 1 point each to the latter risk factors. In the derivation data set, the 30-day postoperative mortality/amputation rates in patients with scores of 0, 1, 2, 3, and 4 were 7.7%, 6.4%, 11.1%, 20.4%, and 27.3%, respectively, (P < 0.0001); mortality rates were 1.3%, 2.3%, 4.1%, 7.7%, and 12.1%, respectively, (P < 0.0001); and major amputation rates were 6.4%, 4.3%, 7.1%, 12.7%, and 18.2%, respectively, (P < 0.0001). In the validation data set, the 30-day postoperative mortality/amputation rates in patients with scores of 0, 1, 2, 3, and 4 were 4.8%, 7.5%, 10.1%, 15.9%, and 22.2%, respectively, (P < 0.0001); mortality rates were 0.7%, 2.3%, 4.2%, 5.5%, and 14.8%, respectively, (P < 0.0001); and major amputation rates were 4.6%, 5.3%, 6.4%, 11.0%, and 14.0%, respectively (P = 0.011). Conclusions This simple risk-scoring method can be useful to stratify the immediate postoperative outcome of patients undergoing infrainguinal surgical revascularization for critical lower-limb ischemia.
