Lower shedding of strongylid eggs by Warmblood horses with recurrent airway obstruction compared to unrelated healthy horses

An association between equine recurrent airway obstruction (RAO) and increased resistance to intestinal parasites has been demonstrated in descendants of an RAO-affected stallion. It was hypothesised that members of another high-incidence RAO family (F) and unrelated RAO-affected Warmblood horses (UA) would shed fewer strongylid eggs than unrelated RAO-unaffected pasture mates (PM) under the same environmental conditions. Faecal worm egg counts were performed on faecal samples (63 F, 86 UA, 149 PM) and classified into three categories: 0, 1-100 and >100 eggs per gram. While results for F did not differ from PM, UA were 2.5-times less likely to shed strongylid eggs than PM. RAO-affected Warmblood horses may be more resistant to strongylid nematodes than unrelated unaffected pasture mates and a family history of RAO does not necessarily confer protection against helminth infections.

Imaging appearances of Buerger's disease complications in the upper and lower limbs

Thromboangiitis obliterans (Buerger's disease) is a rare, non-atherosclerotic, segmental, inflammatory vasculitis that most commonly involves small and medium-sized arteries, veins and nerves of the extremities and affects tobacco smokers between the ages of 25 and 45 years. The manifestations of Buerger's disease can be extremely variable and, therefore, awareness of the condition is important for both general and musculoskeletal radiologists. This paper presents the radiological appearance of the sequelae of Buerger's disease involving the upper and lower limbs.

Seroprevalence of Taenia saginata cysticercosis in the federal state of Lower Saxony in Germany

Based on ELISA results from randomly selected serum samples taken from 128 cattle from different administrative and urban districts in the federal state of Lower Saxony in Germany a seroprevalence estimate of Taenia saginata cysticercosis in this area was derived. This estimate was subsequently used to calculate the sample size required in an epidemiological study to determine the actual prevalence of this infection in the cattle population (n = 2 604 767) in this federal state. The sample size was calculated as 1518 and the samples were collected according to the distribution of cattle among the 48 administrative and urban districts in Lower Saxony. The samples were tested with an evaluated antibody ELISA. The results showed a positive antibody titre rate of 8.83% from the total tested samples.

The extended diep flap: extending the possibilities for breast reconstruction with tissue from the lower abdomen

The classical DIEP-flap is considered state-of-the-art in microsurgical autologous breast reconstruction. Some patients may require additional volume to match the contralateral breast. This quality control study prospectively evaluates the feasibility and outcome of a surgical technique, which pursues the volumetric augmentation of the DIEP-flap by harvesting of additional subscarpal fat tissue cranial to the classical flap border.

High rhinovirus burden in lower airways of children with cystic fibrosis

Rhinovirus (RV)-induced pulmonary exacerbations are common in cystic fibrosis (CF) and have been associated with impaired virus clearance by the CF airway epithelium in vitro. Here, we assess in vivo the association of RV prevalence and load with antiviral defense mechanisms, airway inflammation, and lung function parameters in children with CF compared with a control group and children with other chronic respiratory diseases.

Lower complexity bounds in justification logic

Justification Logic studies epistemic and provability phenomena by introducing justifications/proofs into the language in the form of justification terms. Pure justification logics serve as counterparts of traditional modal epistemic logics, and hybrid logics combine epistemic modalities with justification terms. The computational complexity of pure justification logics is typically lower than that of the corresponding modal logics. Moreover, the so-called reflected fragments, which still contain complete information about the respective justification logics, are known to be in~NP for a wide range of justification logics, pure and hybrid alike. This paper shows that, under reasonable additional restrictions, these reflected fragments are NP-complete, thereby proving a matching lower bound. The proof method is then extended to provide a uniform proof that the corresponding full pure justification logics are $\Pi^p_2$-hard, reproving and generalizing an earlier result by Milnikel.

Sacral Neuromodulation for Refractory Lower Urinary Tract Dysfunction: Results of a Nationwide Registry in Switzerland

OBJECTIVE: To assess the efficacy and safety of sacral neuromodulation (SNM) in patients with refractory lower urinary tract dysfunction in Switzerland based on a nationwide registry. PATIENTS AND METHODS: A total of 209 patients (181 females, 28 males) underwent SNM testing between July 2000 and December 2005 in Switzerland. Subjective symptom improvement, bladder/pain diary variables, adverse events, and their management were prospectively registered. RESULTS: SNM testing was successful (defined as improvement of more than 50% in bladder/pain diary variables) in 102 of 209 patients (49%). An implantable pulse generator (IPG) was placed in 91 patients (89% of all successfully tested and 44% of all tested patients). Of the IPG-implanted patients, 71 had urge incontinence, 13 nonobstructive chronic urinary retention, and 7 chronic pelvic pain syndrome. After a median follow-up of 24 mo, SNM was successful in 64 of the 91 IPG-implanted patients (70%) but failed in 27 patients. SNM was continued in 15 of the 27 patients considered failures, because following troubleshooting SNM response improved subjectively and the patients were satisfied. However, improvement in bladder/pain diary variables remained less than 50%. In the other 12 patients both the leads and the IPG were explanted. During the test phase and during/following IPG implantation, 6% (12 of 209) and 11% (10 of 91) adverse event rates and 1% (3 of 209) and 7% (6 of 91) surgical revision rates were reported, respectively. CONCLUSIONS: SNM is an effective and safe treatment for refractory lower urinary tract dysfunction. Adverse events are usually transient and can be treated effectively.
