Effect of suturing the femoral portion of a four-strand graft during an ACL reconstruction

2014

Purpose A suture passed along the part of the graft that will be inserted into the femoral tunnel is widely used by surgeons, because it could prevent the graft sliding on the femoral fixation device during pulling from the tibial side. The aim of this study was to evaluate the biomechanical effects of suturing the intratunnel femoral part of the graft during an anterior cruciate ligament (ACL) reconstruction. Methods Bovine digital extensor tendons and tibias were harvested from 20 fresh-frozen mature bovine knees ranging in age from 18 to 24 months. Quadruple-strand bovine tendons were passed through the tibial tunnel and secured distally with a bioabsorbable interference screw. In one ha…

Control of murine hair follicle regression (catagen) by TGF‐β1in vivo

2000

The regression phase of the hair cycle (catagen) is an apoptosis-driven process accompanied by terminal differentiation, proteolysis, and matrix remodeling. As an inhibitor of keratinocyte proliferation and inductor of keratinocyte apoptosis, transforming growth factor beta1 (TGF-beta1) has been proposed to play an important role in catagen regulation. This is suggested, for example, by maximal expression of TGF-beta1 and its receptors during late anagen and the onset of catagen of the hair cycle. We examined the potential involvement of TGF-beta1 in catagen control. We compared the first spontaneous entry of hair follicles into catagen between TGF-beta1 null mice and age-matched wild-type …

Anti-androgens for the treatment of hirsutism.

2002

Many alternatives exist for treating hirsutism. Based on an analysis of scientific literature and on the experiences of the author, the most common anti-androgen agents are discussed in this review. Androgen receptor blockers (cyproterone acetate, flutamide and spironolactone), 5 alpha-reductase inhibitors (finasteride) and androgen-suppressing agents (gonadotrophin-releasing hormone [GnRH] agonists, oestroprogestins, corticosteroids and insulin-sensitising agents) are evaluated and compared. The importance of diagnosis in choosing the most appropriate anti-androgen treatment is also discussed.

Endoscopic treatment of gastroesophageal reflux disease.

2005

Gastroesophageal reflux disease is a common chronic disorder which has a severe effect on the patient's quality of life. In view of the high cost of medical therapy and the limitations of surgery, a variety of endoscopic techniques have been developed for the treatment of this condition, and these have shown apparently encouraging results, at least in the short term. However, promising results have been obtained in only around two-thirds of patients over a short-term follow-up period of about 6 months. Moreover, several inconsistencies have emerged between the efficacy of this form of treatment in improving symptoms and quality of life and a lack of improvement of objective parameters, such…

Diagnosis, phenotype, and prevalence of polycystic ovary syndrome.

2006

New diagnostic criteria for polycystic ovary syndrome (PCOS) suggested three main phenotypes: classic (hyperandrogenism and anovulation), ovulatory, and normoandrogenic. However, it is unclear whether the normoandrogenic phenotype actually represents PCOS. Overall, 6% to 8% of reproductive-aged women suffer from PCOS, making this disorder one of the most common endocrine abnormalities.

Eight-point compass rose underlay technique in 72 consecutive elderly patients with large incisional hernia

2011

Summary Background Repair of incisional hernia (IH) in the elderly is a challenge for the surgeon. Primary closure is preferable but is not always possible because of high recurrence rates of IH repaired without a prosthesis and/or possible respiratory and cardiovascular complications due to extreme tension of the margins. We report our experience with underlay mesh placement in elderly patients with large IH. Methods A total of 72 patients from January 2003 to December 2009 underwent IH repair involving placement of an intraperitoneal Gore® DualMesh® prosthesis. The prosthesis was first anchored at eight points in a compass rose pattern using a Gore® suture passer and then firmly secured t…

Argon laser suture lysis following glaucoma filtering surgery – A short introduction to the procedure

2010

Abstract Background Trabeculectomy is the most commonly performed glaucoma filtering surgery. The success of the outcome of an operation to reduce the intraocular pressure (IOP) is dependent on postoperative wound modulation by antimetabolite therapy and by flow regulation of the filtering bleb, which can be achieved by argon laser suture lysis. Methods and case report Postoperative IOP controls, examination of bleb formation and bleb massage can lead to the decision to perform up to four argon laser suture lyses in order to reduce IOP and enhance aqueous humor flow and bleb formation. The procedure is described here in a case report. Conclusion After glaucoma filtering surgery, argon laser…

Computertomographie der Nieren nach Tumorenukleation

1994

Two weeks to 120 months after enucleation of renal tumours the postoperative defects were correctly localized by renal computed tomography in 34 patients. Typical defect morphology was either wedge-shaped or concave. No dependence on tumour localization, tumour size, operative technique or a certain surgeon was observed. The cortical defects were smaller (mean 2.0 cm) than the original, prominent tumours (mean 3.4 cm). In small defects without tension suture of the capsule is sufficient, leading to minor defects. Larger defects were closed with a retroperitoneal or free peritoneal fat flap resulting in larger residual defects. In case of intra- or postoperative bleeding, CT could demonstrat…

Suture needles in Oral Surgery: Alterations depending on the type and number of sutures

2011

This study examined whether the number and type of sutures used in oral surgery influence two ad hoc variables (incision plane and displaced area), which are two variables related to whether the suture needle is suitable for the task. Seventy-five TB-15 needles were studied, which were used to suture between zero and three mucosa and/subperiosteal sutures, producing 15 groups with 5 needles in each one. The incision plane and displaced area were measured for each group, which are two variables related to how the needle has worn and altered. Statistical treatment was conducted using the Kruskal-Wallis H test to compare multiple values and the Mann-Whitney U test to compare pairs. A multi-sta…
