Van de Nederlandse bevolking van 12 jaar en ouder heeft circa 8% een tatoetage.1 Bij tatoeering wordt exogeen pigment met naalden in de dermis gebracht. Tatoeage-inkten zijn mengsels van kleine deeltjes organische of synthetische kleurstof, metaalzouten en uiteenlopende toevoegingen.

Breast carcinoma frequently metastasises to bone, most often to the thoracic and lumbosacral spine. 3 women, aged 66, 47 and 54 years, who had been previously treated for breast cancer presented with sternal pain. Bone scintigraphy revealed a solitary sternal hot spot in all 3 patients. In the final diagnosis, 1 patient had nonmalignant reactive changes, which required no further therapy; 1 patient had a bone metastasis, which was treated with radiation therapy and tamoxifen; and 1 patient had radionecrotic tissue, which was treated with hyperbaric oxygen therapy. Symptoms resolved in all 3 patients. Skeletal scintigraphy is the most sensitive method for detecting bone metastases, but it is not specific. Bone metastases are usually multifocal, but sometimes a solitary bone lesion is found. A solitary sternal metastasis must be differentiated from other sternal disorders. Various treatment options exist for patients who are ultimately diagnosed with a solitary sternal metastasis.

In The Netherlands each year there are 2300 new patients with a squamous-cell carcinoma of the larynx, pharynx and oral cavity, and of these, one-third has a locally regionally advanced tumour. An operation can then lead to an unacceptable loss of function, whilst radiotherapy alone has no effect on survival. Compared to radiotherapy alone, the combination of radiotherapy and chemotherapy containing cisplatin, when administered simultaneously, produces a higher percentage of patients with loco-regional control and a higher 3-year survival percentage. This improvement in treatment results is accompanied by an increased acute toxicity.

On two separate occasions, a total of eight subjects ate tuna fish. Three out of four persons in the first case (a father aged 54, a mother aged 51 and a daughter aged 24 years) and one out of four persons in the second case (a 28-year-old woman) experienced erythema, respiratory distress and diarrhoea shortly after eating the fish. These symptoms are indicative of scombrotoxic fish poisoning. Histamine is produced in the muscle tissue of scombroid fish, such as tuna or mackerel, if it is kept at a temperature which is too high. Since the concentration of histamine is not evenly distributed through the fish's flesh, not everyone who eats the same fish will become ill to the same extent, and some may not even become ill at all. Furthermore, since the complaints are often mild and of short duration, most patients do not seek medical help, and probably few cases are officially reported. Despite the fact that sometimes only one person from a group of people eating the same fish becomes ill, and that the clinical complaints resemble an IgE-mediated allergic reaction, the illness is a food-borne intoxication with exogenous histamine. Therefore, patients can safely eat the same type of fish again.

In 1995, a new privacy law was introduced in the Netherlands. According to this law, medical records should be saved for 10 years, and then destroyed, unless keeping the records for a longer period follows reasonably from the duties of the treating physician (as is the case, for example, when treating patients with a chronic disease). There are serious concerns with regard to the future availability of medical record data for clinical research and patient care after 2005. Evaluation of the late effects of many medical treatments will no longer be possible in the Netherlands. Patient care, particularly genetic counselling, will be also seriously compromised. As a possible solution the profession might name diagnoses and treatments regarding for which, from the point of view of good care, it is necessary for files to be kept for longer than 10 years. For a uniform nationwide policy it would be better if all files, perhaps after sorting by diagnosis and treatment, should be obligatorily kept for much longer than 10 years, preferably for the duration of the life expectancy.

Tropical eosinophilia was diagnosed in two patients from India. This appears to be the first report on this exotic condition in the Netherlands. Tropical eosinophilia is characterised by hypereosinophilia, asthma-like attacks of wheezing and non-productive cough, non-specific findings on the chest X-ray in combination with general malaise, subfebrile temperatures, weight loss and lymphadenopathy. Although the syndrome is caused by an infection with Filaria, classical symptoms of filarial infection are characteristically absent. The main diagnostic criteria are hypereosinophilia and asthma-like attacks in subjects from regions where Filaria is endemic, high IgE titers, high antifilarial antibody titers and cure following one or more treatment courses with diethylcarbamazine. These case reports illustrate the importance of the assessment of the number of eosinophil cells in the peripheral blood in the diagnosis of tropical disease.
