Aluminiumoxidkeramik in der rekonstruktiven Nasenchirurgie. Histologische Untersuchungen am Kaninchen

Summary In cases where a reconstruction of defects in the larynx, oral cavity, the pharynx or in the ear region has been performed using skin flaps, a temporary fistula is formed at the point of entry.This fistula can be closed later after the flap has taken and the flap pedicle dissected.We would like to demonstrate with some examples that with the use of deepithelisation it is possible to achieve a primary wound closure. This way no temporary fistula results and additional surgery is avoided in many cases.Furthermore flap deepithelisation offers a way to bring good vascularised tissue under the skin and cover subcutaneous defects, for example those after radiotherapy.

Identification of accessory bile ducts at cholecystectomy

The presence of accessory channels between the liver and extrahepatic bile ducts has long been recognised by anatomists and the division of such ducts may be a cause of bile leakage following cholecystectomy. However, visualisation of accessory bile ducts at operation is difficult as they are often small and sometimes less than 1 mm in diameter. Cholangiography has been used to help in the identification of accessory ducts in 50 patients included in a prospective trial. X-rays were taken after dissection of the gall bladder from its bed and extravasation of contrast was seen on five occasions (10%) suggesting leakage from divided accessory ducts. The identification of damage to accessory bile ducts in 10% of patients suggests that this may occur more frequently than previously supposed.     

HLA-DR typing in identical twins with insulin-dependent diabetes: difference between concordant and discordant pairs

A total of 106 pairs of identical twins, of whom 56 were concordant and 50 discordant for insulin-dependent diabetes, were typed for HLA-DR. In both the concordant and discordant groups there was a high prevalence of the antigens DR3 and DR4, a low prevalence of DR5 and DR7, and a virtual absence of DR2. The heterozygous phenotype DR3,DR4 was more prevalent in concordant than discordant pairs. This was therefore the first demonstration of a genetic difference between concordant and discordant identical twin pairs. These findings suggest that possession of both DR3 and DR4 antigens confers a greater genetic predisposition to insulin-dependent diabetes than does the possession of either antigen alone.     

Hernia of the inferior lumbar space. A cause of back pain

Twenty hernias of incarcerated fat at the inferior lumbar space were seen during a 23-year period. The usual complaint was a painful mass that caused a backache. The condition was more common in women and girls than in men (18 v two). The wider female pelvis creates a larger inferior lumbar space, which predisposes to the hernia. The hernia appears through a defect of the covering lumbodorsal fascia. Increased physical activity in young women seemed to be a causative factor. One patient had acute strangulation of incarcerated fat. Nineteen of the 20 hernias were treated with surgical excision and repair of the lumbodorsal fascial defect. Results of treatment were good. Though rare, hernias of the inferior lumbar space should be considered when back pain is present, particularly in a young, athletic woman.
