Diastasis of the rectus abdominis muscle is a common condition. There are no generally accepted criteria for diagnosis or treatment diastasis muscle, which causes uncertainty patient and healthcare providers alike.The consensus document was created by group Swedish surgeons based on structured literature review practical experience.The proposed as follows: (1) diagnosed at clinical examination using caliper ruler measurement. Diagnostic imaging ultrasound other modality, should be performed...

Seventy-five women, of whom 30 had received postoperative radiotherapy, were tested for range motion (ROM) and shoulder strength with a goniometer an isokinetic device (Orthotron II), respectively. On the individual level, irradiated patients exhibited significantly reduced (varying from p < 0.05 to 0.001) all movements compared non-operated side. In contrast, in non-irradiated only flexion was (p 0.05). The same pattern evident where except external rotation 0.001). Non-irradiated...

Abstract During nerve growth, axons are dependent upon contact with matrix components, such as laminins, for elongation, guidance, and trophic support. Semiquantitative in situ hybridization histochemistry immunohistochemistry (IHC) were used to identify laminin chains normal peripheral nerves, during postnatal development, after sciatic transection (SNT), crush (SNC). Laminin α2, α4, β1, β2, γ1 chain mRNAs all expressed at high levels newborn rat nerves declining later developmental stages....

Implant-based reconstruction is performed in the majority of women offered primary for breast cancer.Two different expander implants were compared prospectively. The endpoint was number operations needed each group to obtain patient satisfaction. Secondary endpoints evaluation volume and shape aspects quality life. Seventy consecutive cancer patients randomized either a one-stage with round permanent implant (Becker 25; n=35) or two-stage crescent-shaped (LV 133; n=35), later replaced by...

&lt;b&gt;&lt;i&gt;Background:&lt;/i&gt;&lt;/b&gt; Surgery for Abdominal Rectus Diastasis (ARD) is a controversial topic and some argue that it solely an aesthetic problem. Many symptoms in these patients are indefinite, no objective criteria have been established, indicating which likely to benefit from surgery. This study investigated the correlation between preoperative assessment intraoperative measurement of ARD width, measurements muscle strength....

Myeloid leukemia of Down syndrome has a better prognosis than sporadic pediatric acute myeloid leukemia. Most cases are characterized by additional cytogenetic changes besides the constitutional trisomy 21, but their potential prognostic impact is not known. We, therefore, conducted an international retrospective study clinical characteristics, cytogenetics, treatment, and outcome 451 children with syndrome. All karyotypes were centrally reviewed before assigning patients to subgroups. The...

To investigate the validity and reliability of Biodex system 4 in assessment abdominal strength patients with rectus diastasis, we studied 10 healthy volunteers diastasis more than 3 cm. We assessed test-retest at 30o 60o extension/flexion spinal angles, respectively, isometric muscle without girdle. Reliability was calculated using interclass correlation coefficient (ICC). Validity evaluated by International Physical Activity Questionnaire (IPAQ) a visual analogue scale (VAS) for...

The rates of soft tissue reconstruction and amputation after open tibial fractures have not been studied on a national perspective. We aimed to determine the frequency coverage fracture as well primary secondary rates.Data all patients (> = 15 years) admitted hospital with were extracted from Swedish National Patient Register (1998-2010). All surgical procedures, re-admissions, mechanisms injury analysed accordingly. risk was calculated using logistic regression (adjusted for age, sex,...

Symptoms arising from giant ventral hernia have been considered to be related weakening of the abdominal muscles. The aim this study was investigate relationship between area wall defect and muscle strength measured by validated BioDex system together with a back/abdominal unit. Fifty-two patients (>10 cm wide) underwent CT scan, clinical measurement size prior surgery. areas derived scan were compared forces in modalities extension, flexion isometric contraction. Spearman rank test used...

Repair of large incisional hernias includes the implantation a synthetic mesh, but this may lead to pain, stiffness, infection and enterocutaneous fistulae. Autologous full-thickness skin graft as on-lay reinforcement has been tested in eight high-risk patients proof-of-concept study, with satisfactory results. In multicenter randomized use was compared mesh giant ventral hernia repair. Non-smoking > 10 cm wide were repair using an autologous or mesh. The primary endpoint surgical site...

Repair of giant incisional hernia often requires complex surgery and the results conventional methods using synthetic mesh as reinforcement are unsatisfactory, with high recurrence complication rates. Our hypothesis was that full-thickness skin graft (FTSG) provides an alternative material for repair outcome is improved. The aim this study to compare FTSG materials currently used in hernia.

Growing awareness about breast implant-related adverse events has stimulated the demand for large, independent data resources. For this, from implant registries could be combined. However, that never been achieved yet.Real-world four currently active national were used. All permanent implants Australian, Dutch, Swedish, and American included. A subpopulation present across all between 2015 2018 was subsequently selected, including only inserted during primary surgery reconstruction or...
