[Rieger-Marchac flaps: Complications and patient satisfaction].

Purpose: Like all surgical procedures, dorsal nasal flaps may be followed by both early and late complications. The aim of this study was to evaluate the surgical complications and cosmetic outcome of dorsal nasal flaps over a 7-year period in an academic dermatologic surgery unit.

Patients And Methods: Data were collected retrospectively for all patients undergoing dorsal nasal flap between 1 January 2006 and 31 December 2013.

Use of Masquelet technique in treatment of septic and atrophic fracture nonunion.

Background: Treatment of atrophic non-unions and large bone defects or infections remains a challenging task for the treating surgeon. In the herein study, we present our experience of the 'Masquelet technique' according to the 'diamond concept' for the treatment of complex long bone reconstruction procedures.

Methods: Between February 2010 and March 2015, 150 patients (mean age 51.

[Tibial defects and infected non-unions : Treatment results after Masquelet technique].

Background: The treatment of non-unions with large bone defects or osteitis is a major challenge in orthopedic and trauma surgery. A new concept of therapy is a two-step procedure: Masquelet technique according to the diamond concept.

Methods: Between February 2010 and June 2014, 55 patients with tibia non-unions or infections were treated in a two-step Masquelet technique in our center.

[PIBF - Progesterone-Induced Blocking Factor].

Pregnancy is a unique immunological situation in which 2 allogeneic organisms live in intimate symbiosis without developing rejection reactions. At different locations, interfaces exist between mother and foetus with direct contact between both individuals: 1) maternal blood surrounds foetal villi, which are covered with syncitiotrophoblast cells; 2) cytotrophoblast cells invade the decidua, in which they touch tissue lymphocytes; 3) trophoblast cells, which substitute endothelium of maternal arterioles filled with maternal blood; and 4) trophoblast particles, which are expressed from syncytiotrophoblast and circulate within the maternal blood until they settle in the lung capillaries, where they become degraded by alveolar macrophages. Several factors are known which support the specific immunotolerance of the mother to her foetus and are focussed by current research in reproductive immunology.

"I" becomes "L": modification of vertical mammaplasty.

The problems of the vertical mammaplasty by Lejour (i.e., gathering the skin envelope in one vertical suture, frequent secondary healing problems, and later sagging of the inferior glandular part in the case of large and very large breasts) are well known.
