Review[Umbilical cord blood from an unrelated donor as source for stem cell transplantations in inborn errors of metabolism].
In certain inborn errors of metabolism, an allogeneic stem cell transplantation is able to prevent disease progression. This is only possible when the stem cell transplantation (SCT) is performed early in life, before cerebral involvement has occurred. In addition to bone marrow and peripheral blood, unrelated umbilical cord blood appears to be an effective stem cell source as well. ⋯ There are also potential disadvantages attached to the use of umbilical blood as stem cell source: the possibility of only one donation per donor and less adaptive immunity following umbilical blood SCT with an increased risk of reactivation of a previous viral infection. However, these disadvantages are less applicable to young children with inborn errors of metabolism. The improvement of transplantation techniques and the availability of this new stem cell source could improve the success rate of this procedure and consequently the prognosis of these severely affected patients.

Nearly 60% of the Dutch population undergoing surgery is over the age of 65. The elderly are at higher risk of developing perioperative complications (e.g. myocardial infarction, pneumonia or delirium), that lead to a prolonged hospital stay or death. ⋯ The type of anaesthesia, fluid management and pain management strongly influences the outcome of surgery and the way this is experienced by the patient. Recent developments focus on multimodal perioperative care of the older patient to shorten hospital stay, using minimal invasive surgery, postoperative anaesthesiology rounds and early geriatric consultation.

Comment Review[Delayed cord clamping in the interest of the newborn child].
The importance of delayed cord clamping, both for the preterm and for the term newborn, for the prevention ofneonatal anaemia (during the neonatal period and/or at the age of3 months) and furthermore to reduce the need of blood transfusions, has recently been demonstrated in controlled clinical studies and meta-analyses. Physiological and pathophysiological factors also provide a rationale for delayed cord clamping: neonatal blood volume may increase by 32% if cord clamping is delayed until the umbilical cord has completely stopped pulsating. A slow transition, involving closure of the ductus arteriosus and the foramen ovale cordis and gradual filling of the neonatal systemic circulation, contributes to the opening of the alveoli due to perfusion of the alveolar capillaries. ⋯ As a standard procedure, the baby's umbilical cord should not be clamped until at least 3 minutes have passed. One should wait at least 30 seconds during the birth of children for whom a more active approach is necessary. Of all people, these children will benefit from a good Hb level.

Review[Medicine is not gender-neutral: influence of physician sex on medical care].
Many studies have shown that men and women differ in communication styles. The question is whether these differences also play a role during medical consultation. Potential differences between male and female physicians that have been investigated, are differences in doctor-patient communication, the diagnostic process and treatment. ⋯ Within the medical profession, male and female medical students are socialised differently, and professional socialisation does not overcome differences in gender roles. Patients are generally more satisfied with female physicians than male physicians. Knowledge of and insight into these processes is essential for improving the quality of care.

--Cholangiocarcinoma is a rare malignancy originating from the biliary epithelium. The disease can arise anywhere in the biliary tract: intrahepatic, perihilar or distal. The overall prognosis for cholangiocarcinoma is poor. --The treatment necessitates a multidisciplinary approach. --Radical resection of the extrahepatic bile ducts, usually in combination with concomitant partial liver resection, remains the only curative treatment. --Liver transplantation in combination with neoadjuvant chemoradiation therapy seems to be promising in a highly selected group of patients. --Palliative treatment should be targeted at adequate biliary drainage, preferably by stenting. --Radiotherapy and systemic chemotherapy are not standard treatment and should be applied in an experimental setting only. --New options such as photodynamic therapy and tyrosine kinase inhibitors are promising, but still experimental treatments.
