In vitro relative cytotoxicity (IC ()/IC () of ()-3-(4'-methylbenzylidene)-4-chromanone () towards human Molt 4/C8 and CEM T-lymphocytes showed a >50-fold increase in comparison to those of the respective tetralone derivative (). On the other hand, such an increase was not observed in the analogous 4-OCH ( and ) derivatives. In order to study whether thiol reactivity-as a possible basis of the mechanism of action-correlates with the observed cytotoxicities, the kinetics of the non-enzyme catalyzed reactions with reduced glutathione (GSH) and N-acetylcysteine (NAC) of and were investigated.

The idiopathic granulomatous mastitis is a rare, benign inflammatory laesion of the breast which can mimic malignancy in it's clinical appearance. We would like to draw attention to this differential diagnostic problem based on the cases of our Surgery Department.

This way a deficiency emerges, which needs to be restored. Reconstruction with split skin graft (SSG) is a most common way of recovery, but thoracodorsal artery perforator (TDAP) fasciocutneous flap delivers better functional and aesthetic results.

Reconstruction with pure latissimus dorsi flap is useful option and due to endoscopic harvest large scar on the back can be avoided. The skin sparing mastectomy and even the sentinel lymph node biopsy or lymphadenectomy can be performed using a single incision in the axilla.

Presentation Of Case: A 66-year-old woman was referred with massive incarcerated left inguinal hernia, following acute surgery on a femoral vein leasion and numerous attempts at repair and subsequent recurrences. There was complete absence of the left inguinal ligament.
Introduction: Handling problems in the head and neck region often requires a close cooperation between allied professions, just as in the challenging cases presented by us. Cases and methodology: With the first patient, we performed a radical surgery on the left side of the face due to recidivious basal cell carcinoma, followed by reconstruction using a Type I chimeric anterolateral thigh flap (ALT), while in the case of the second patient, we carried out a radical surgery on the right side of the face due to epithelial carcinoma and reconstruction with a Type I chimeric thoracodorsal flap. With our third patient, a reconstructive operation was performed due to left-sided congenital hemifacial microsomia, using a profunda artery perforator (PAP) flap.

To improve the high incidence of complications, minimal invasive interventions were introduced. The results of the thoracoscopically and laparoscopically performed esophageal resection (McKeown) was investigated after 20 cases and the technical details of the surgical intervention are presented.

As the conservative ways of treatment (diet, training, etc.) in most cases does not lead to effective and long term weight loss, there is an increasing need for the metabolic surgical interventions.

One third of the cases requires surgical correction, not rarely as an emergency. The different methods of repair can be quite demanding and the complication rates are high.

The complete removal of the colon mucosa is essential regarding the late complications and at the same time the atraumatic surgical technique is very important concerning on the long term functional results. Both aspects seems to be answered by the stapled ileo-anal anastomosis using a "procedure for prolaps and haemorrhoids (PPH)" stapler applied by us since 2000.

In addition, using pharmacological agents we blocked some signal transduction pathways (Ca(2+) influx, kinases, phospholipases, proteasomic protein degradation) to find out how they contribute to gene expression during PTI. PTI is the first defense response of plant cells to microbes, elicited by their widely conserved molecular patterns.

The aim of the present study was to analyze reconstruction with LDI in terms of quality of life, cosmesis and patient satisfaction. A chart analysis was carried out with the first ten patients who underwent breast reconstruction with LDI.

However, a desire for an alternative, thin fasciocutaneous flap has led to the use of the median sural artery perforator flap.
Methods: Three patients had reconstructive surgery used MSAP flaps, after radical tumor excision.
Perineal wound healing problems following extended abdomino-perineal resection of ano-rectal cancer represent a great challenge to the surgeon. Perineal soft-tissue reconstruction with a myocutan flap was thought to reduce surgical wound healing complications. A review of the relevant literature was carried out on perineal soft-tissue reconstruction with rectus abdominis myocutan (VRAM) flap following extended abdomino-perineal rectal resection for cancer.

Previously performed lower median laparotomy can cause some difficulties in cases when more volume is needed than the DIEP flap harvested from one side can provide. We performed breast reconstruction using double hemi-DIEP flaps in three of the cases discussed.

Historically, patients with central breast cancers were not offered breast conservation surgery but conventional mastectomy only. The relatively frequent nipple-areola-complex involvement and consequent nipple-areolar resections with an adequate safety margin around the tumor usually result in an unacceptable cosmetic result.

Anatomy of the vessels supplying this flap is recognized but it may have some rare and unexpected variations. In this case report we discuss the reconstruction of the middle and lateral parts of the mandible which was resected due to a T4 gingival tumor.

Etiology and adequate operative technique of that are debated widely up to now, and recurrence rates remained high despite various surgical techniques applied. In cases of unsuccessfully operated and repeatedly recurrent SDC a fascio-cutaneous flap on the first perforating branch of the inferior gluteal artery (IGA) is a definitive procedure.

Recurrent subareolar abscess is an uncommon benign disease of the breast, which is caused by peri-ductal mastitis with various etiology. Radical surgical procedure is necessary for cure instead of inadequate courses of antibiotics or incisions. In some cases the use of the pectoral muscle sling flap can be an alternative technique for the treatment of recurrent subareolar abscess after repeated standard surgical treatment.
