Diversity in sexual health: Problems and dilemmas

The increase in migrant populations in western Europe has led to specific problems and dilemmas in the area of sexual and reproductive health and service provision. In general, these problems and dilemmas can be divided into four categories: (1) epidemiology of diseases and risk factors; (2) psychosocial and cultural aspects; (3) communication; and (4) moral and ethical dilemmas.

Regarding epidemiology, there is an increased prevalence in migrant groups of unwanted pregnancy and abortion, HIV/STDs, and sexual violence. Effective contraceptive use is hampered by knowledge deficits, uncertain living conditions, ambivalence regarding the use of contraceptives, and problems accessing (information on) contraception. Psychosocial and cultural aspects relate to the norms and attitudes individuals and groups have regarding the family, social relationships, sexuality, and gender. These norms and attitudes have an impact on the sexual and reproductive choices people make and the possibilities and restrictions they feel in this respect. Problems in communication concern not only language but also communication styles, the way patients present their problems, and the expectations they have from the service provider. Communication problems inevitably lead to a lower quality of care. Moral and ethical dilemmas arise where cultures collide, for example regarding sexuality education and virginity problems. Two examples of practical situations in which migrant patients ask for help with sexual or reproductive health problems will be described.     

Ultrastructural evidence for the presence of ferritin-iron in the biliary system of patients with iron overload

Ferritin-like particles were observed in bile canaliculi of patients with iron overload. These particles have been further investigated by: a staining method enhancing the size and contrast of ferritin protein, and electron probe microanalysis detecting the presence of the elements iron and phosphorus. Morphological observation of coated vesicles in the cytoplasm adjacent to the bile canaliculi and coated pits in the canalicular membrane suggests a transport mechanism via membrane-bound organelles. Support is given to the theory that part of the iron, stored in the liver, leaves the hepatocyte by excretion of ferritin into the bile.

Progressive supranuclear palsy: pathology and genetics

Progressive supranuclear palsy (PSP) is an atypical Parkinsonian disorder associated with progressive axial rigidity, vertical gaze palsy, dysarthria and dysphagia. Neuropathologically, the subthalamic nucleus and brainstem, especially the midbrain tectum and the superior cerebellar peduncle, show atrophy. The substantia nigra shows loss of pigment corresponding to nigrostriatal dopaminergic degeneration. Microscopic findings include neuronal loss, gliosis and neurofibrillary tangles in basal ganglia, diencephalon and brainstem. Characteristic tau pathology is also found in glia. The major genetic risk factor for sporadic PSP is a common variant in the gene encoding microtubule-associated protein tau (MAPT) and recent studies have suggested that this may result in the altered expression of specific tau protein isoforms. Imaging studies suggest that there may be sensitive and specific means to differentiate PSP from other parkinsonian disorders, but identification of a diagnostic biomarker is still elusive.     

Senior medical students' appraisal of CanMEDS competencies

CONTEXT: In 2003 the Dutch Central College of Medical Specialties presented guidelines for the modernisation of all medical specialty training programmes in the Netherlands. These guidelines are based to a large extent on the CanMEDS (Canadian Medical Education Directives for Specialists) 2000 model, which defines 7 roles for medical specialists. This model was adjusted to the Dutch situation. The roles were converted to 7 fields of competency: Medical Performance; Communication; Collaboration; Knowledge and Science; Community Performance; Management, and Professionalism. OBJECTIVE: As changes in postgraduate training will probably be most effective if future trainees recognise their value, we set out to determine how senior medical students rated these fields of competency in terms of their importance. METHODS: We carried out a study at University Medical Centre (UMC) Utrecht, the Netherlands, in which 80 Year 6 medical students answered a questionnaire in which they rated the importance of each of 28 key competencies within the 7 competency fields. RESULTS: Although all key competencies were regarded as important (averages > or = 3.8), Professionalism and Communication scored highest on the student ratings. Management was assessed as least important. CONCLUSIONS: It is interesting that medical students acknowledged the importance of competencies other than those involving medical expertise and performance. It confirms the opinion that educating doctors is currently viewed as much more than providing theoretical and clinical knowledge and skills. The CanMEDS framework is appreciated by Dutch medical students. The fact that all competencies are seen as important adds to their face validity and therefore to their usefulness as a basis for postgraduate training.     

FTDP‐17 with Pick body‐like inclusions associated with a novel tau mutation,p.E372G

Mutations in microtubule‐associated protein tau gene (MAPT) cause frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP‐17). Here, we describe a patient with FTDP‐17 and a novel missense mutation in exon 13 of MAPT, p.E372G. We compare clinicopathologic features of this patient to two previously unreported patients with another exon 13 mutation, p.G389R. The patient with the p.E372G mutation was a 40‐year‐old man with behavioral variant frontotemporal dementia (bvFTD), who subsequently developed agrammatic speech and parkinsonism. One of the FTDP‐17 patients with p.G389R mutation presented at age 24 with agrammatic variant of primary progressive aphasia, and subsequently behavioral dysfunction. The other presented at age 53 with bvFTD, followed by agrammatic speech and corticobasal syndrome. Neuropathologic features of FTDP‐17 due to p.E372G were similar to those of p.G389R, including tau‐immunoreactive Pick body‐like neuronal inclusions and swollen, tapering thread‐like processes in white matter immunoreactive for 3‐repeat and 4‐repeat tau. Biochemical analysis of insoluble tau showed similar isoform compositions in p.E372G and p.G389R. Functional studies of the p.E372G mutation showed marked increase in tau filament formation and its reduced ability to promote microtubule assembly. Together these findings indicate that p.E372G is a pathogenic MAPT mutation that causes FTDP‐17 similar to p.G389R.
