A short-term follow-up comparison of two trans-obturator tape procedures

The objective of the study was to compare the clinical outcomes at the short-term follow-ups of two novel transobturator mid-urethral sling procedures – the transobturator tape (TOT) procedure and the tension-free vaginal tape (TVT)-obturator procedure. The study cohort consisted two groups of 40 women with urodynamically proven stress urinary incontinence (SUI). The patients in one group underwent the TOT procedure, performed according to Delorme (Prog Urol 11:1306–1313, 2001); those in the second group underwent the TVT-obturator operation, performed according to de Leval (Eur Urol 44:724–730, 2003). Intra-operative diagnostic cystoscopy was not performed with either the TVT-obturator or the TOT procedures. The average follow-up was 12 months. The two patient groups were similar in terms of demographic and therapeutic criteria, except for patient age, which was significantly younger in the TVT-obturator group. Previously reported TVT-related operative complications, such as bladder penetration, intra-operative bleeding, field infection and post-operative pelvic floor relaxation, were not observed in patients of either group. Bowel and urethral injuries were also not recorded. The therapeutic failure rates were 10% for the TOT procedure and 5% for the TVT-obturator procedure. Urinary frequency and urgency post-operatively were reported in 25% of the TOT patients and 19% of the TVT-obturator patients, pelvic or vaginal pain affected 10% of the TOT and 5% of the TVT-obturator patients, while post-operative voiding difficulty was experienced by 12.5% of the TOT and 7.5% of the TVT-obturator patients. None of the above-mentioned differences between the two patient groups were of statistical significance. The TVT-obturator and TOT procedures, both minimally invasive, novel, mid-urethral sling procedures, seem to be safe, easy-to-perform and effective in treating female SUI. The patients of both study groups suffered less intra- and post-operative surgical complications than previously been reported in connection with the TVT operation. The TVT-obturator patients had fewer therapeutic failures, less post-operative urinary frequency and urgency, less pelvic pain and less voiding difficulty. All of these findings, however, had no statistical significance; consequently, long-term comparative data collection will be required before solid conclusions can be drawn on the superiority of either of these two operative techniques.     

Cholesteryl Ester Transfer Protein (CETP) Genetic Variation and Early Onset of Non‐Fatal Myocardial Infarction

Although Cholesteryl Ester Transfer Protein (CETP) mediates the transfer of cholesteryl esters and triglycerides between lipoprotein particles and thus plays a crucial role in reverse cholesterol transport, the association of variations in the CETP gene with acute myocardial infarction (MI) remains unclear. In this study we examined whether common genetic variation in the CETP gene is related to early‐onset non‐fatal MI risk in a population‐based case‐control study from western Washington State. Genotyping for the CETP ?2708 G/A, ?971 A/G, ?629 A/C, Intron‐I TaqI G/A and exon‐14 A/G (I405V) SNPs was performed in 578 cases with first acute non‐fatal MI and in 666 demographically similar controls, free of clinical cardiovascular disease, identified randomly from the community. In‐person interviews and non‐fasting blood specimens provided data on coronary heart disease risk factors. In men, there was little evidence for an association between single SNPs and MI risk, but in women the age‐ and race‐adjusted OR was found to be significant in 4 out of the 5 CETP single variants. Haplotype analysis revealed two haplotypes associated with MI risk among men. As compared to men homozygous for the most common haplotype D (?2708 G, ?971 G, ?629 C, TaqI G and exon‐14 A), the fully‐adjusted multiplicative model identified haplotype G (?2708 G, ?971 A, ?629 A, TaqI G and exon‐14 G) was associated with a 4.0‐6.0‐fold increased risk of MI for each additional copy; [95%CI 2.4–14.8] and haplotype B (?2708 G, ?971 G, ?629 A, TaqI A and exon‐14 A) showed a significant decreased risk for early onset MI [OR = 0.18; 95%CI 0.04 – 0.75]. An evolutionary‐based haplotype analysis indicated that the two haplotypes associated with the MI risk are most evolutionarily divergent from the other haplotypes. Variation at the CETP gene locus is associated with the risk of early‐onset non‐fatal MI. This association was found to be independent of HDL‐C levels. These data and the sex‐specific findings require confirmation in other populations.     

Familial Mediterranean fever (FMF)-response to TNF-blockers used for treatment of FMF patients with concurrent inflammatory diseases

ObjectiveFamilial Mediterranean fever (FMF) is the most common interleukin 1 (IL-1)-driven monogenic autoinflammatory disease. Yet published data also suggest that tumor necrosis factor (TNF) may have a role in the pathogenesis of FMF and may serve as a target for treatment. In the present study we evaluate this hypothesis.MethodsTo this goal, we studied the incidental effect on FMF of TNF-directed treatment, administered to colchicine-refractory FMF patients for the management of a concurrent inflammatory disease. The rates of FMF patients and of treatments with complete or nearly complete FMF response were determined, based on the number of FMF attacks during TNF-blocker exposures. The possible effect of various FMF and non-FMF features on the outcome was determined using comparative analysis. Patients were identified and data were retrieved using electronic files from the FMF clinic.ResultsTwenty-six patients were identified, each receiving ≥ 1 of four TNF-blockers for a mean duration of 27.6 ± 16.4 months. The TNF-blockers were found to induce complete or nearly complete FMF response in 10 (38.5%) of the patients, and in 13 of 50 (26%) exposures. No clinical, genetic, demographic, or therapeutic feature could predict which FMF patient would respond favorably to TNF-blocker therapy.ConclusionThis study suggests that TNF-blockers may be beneficial for a small proportion of colchicine-resistant FMF patients.     

Effects of Systemic Hyperoxia on Eustachian Tube Ventilatory Function

Middle ear negative pressure and effusions, decreased middle ear compliance, and abnormal tympanometry results have been described after diving on oxygen. Middle ear gas hyperoxia has been shown to down-regulate the eustachian tube ventilatory function (ETVF). The purpose of the present study was to investigate to what extent systemic hyperoxia in the face of air-equivalent middle ear gas composition might interfere with the ETVF. ETVF was investigated in four young adult female cynomolgus monkeys by the forced-response and inflation-deflation tests using air while the animals breathed either room air or 100% normobaric oxygen. Higher opening, closing, and steady-state pressures were observed under systemic hyperoxia. The percentage of the applied pressure equalized, and the maximal pressure change on a single swallow in the deflation test were both lower under hyperoxic conditions. The results show that systemic hyperoxia might impair ETVF. This observation adds to our understanding of the pathophysiology of middle ear dysfunction observed after diving on oxygen.     

One intrauterine device lost, two found

During a search for a recently inserted, lost intrauterine device (IUD), a pelvic x-ray found two devices. One of the IUDs had been inserted 9 years earlier and was thought expelled.     

Ultrasound-diagnosed puerperal osteopenia in young primiparas

OBJECTIVE: To study whether osteopenia occurs following pregnancy and to evaluate its severity in young primiparas. STUDY DESIGN: A prospective case control study. Sixty-one young primigravidae early after birth and 59 nulligravidae matched for age and BMI participated in the study. Bone status was examined using ultrasonic bone transmission velocity over the tibia; Z-score and T-score for bone density were calculated. Serum bone alkaline phosphatase, osteocalcin and urinary N-telopeptide crosslinks were evaluated as bone remodeling biochemical markers. RESULTS: Ultrasonic parameters of bone status following delivery were significantly lower in the puerperal group as compared to the nulligravida group. Serum mean bone alkaline phosphatase levels and urinary N-telopeptide crosslinks secretion were higher by 50% in the puerperal group, while serum osteocalcin levels were significantly lower (by 25%) than in the nulligravida controls. A positive correlation between ultrasonic measurements and biochemical markers was demonstrated in the postpartum group, whereas the control group showed a negative correlation. CONCLUSION: Women at their early puerperium demonstrate a significant cortical bone mass reduction as measured by ultrasonograph and markers of bone turnover. It appears that pregnancy is a state of unbalanced accelerated bone turnover that may be associated with reduced osteoblastic activity.
