RESUMO
Patent Blue V (PBV) is a blue dye solution which is used to visualize lymphatic vessels for surgical procedures. There has been some conflicting reports about the influence of this dye solution on pulse oximetry and haemoximetry, why we decided to: 1) produce a spectrum of PBV in plasma, 2) measure absorbances of full blood before and after addition of PBV and 3) to record the effect on the pulse oximeter and haemoximeter of an intradermal injection of PBV to a patient. Computer analysis of the blood gas measurements were carried out by the Oxygen Status Algorithm (OSA). The spectrum of PBV demonstrated a peak absorption at 640 nm and correspondingly the absorbances of the haemoximeter increased most significantly at 622 and 636 nm. These changes invalidated the determination of haemoglobin pigments, and the results should not be used. Computer analysis interpreted the measurements as a shift of the haemoglobin oxygen binding curve.

Dumping is a common adverse effect of gastrectomy and severe dumping is one of the most intractable conditions in gastroenterology. When medical treatment and diet are insufficient, different operative techniques have been tried, all with an unsatisfactory rate of success. The Lygidakis technique for operative treatment of postgastrectomy-dumping is presented, and results from operations on four patients presented. The results obtained are promising, and Lygidakis operation may be considered as an important alternative to wellknown operative techniques when medical treatment or diet is without effect on severe dumping.

The authors present stress fracture (fatigue fracture). Theories about the cause, the underlying mechanism, etiology, pathology, localisation, diagnoses and treatment are discussed, and two case histories are mentioned. Suitable precautions are recommended for runners. The authors would like to emphasize the importance of further investigations including technetium scintigraphic, in cases where stress fracture is suspected.
