[Is it a sexually transmitted disease?] / Is dit een soa?

STD-associated questions and symptoms are submitted frequently to general practitioners and STD outpatient-clinics. In this teaching article we address 10 important clinical questions regarding epidemiology, risk assessment, testing policy, diagnostics and prevention. STD's form a separate category of infectious diseases because of the role of sexuality. Good communication about sexual behavior is indispensable for an adequate diagnosis. We discuss the recognition of extragenital manifestations of STD, which requires alertness. Estimating the STD-risk based on sexual behavior is essential for testing policy. Persons at high risk are tested for the big five. In other cases testing is based on symptoms and complaints. HIV and syphilis are serious std's. Early detection followed by treatment is important in preventing health damage and preventing further spread. Hiv-indicator-conditions are useful alarm-signs for this purpose. PrEP can help not to acquire hiv and increases sexual health. It can be prescribed by gp's and public health clinicians. But condom-use remains crucial in prevention.

Prevalence of vitamin D deficiency among Turkish, Moroccan, Indian and sub-Sahara African populations in Europe and their countries of origin: an overview.

UNLABELLED: Vitamin D status of nonwestern immigrants in Europe was poor. Vitamin D status of nonwestern populations in their countries of origin varied, being either similar to the immigrant populations in Europe or higher than in European indigenous populations. Vitamin D concentrations in nonwestern immigrant populations should be improved. PURPOSE: The higher the latitude, the less vitamin D is produced in the skin. Most European countries are located at higher latitudes than the countries of origin of their nonwestern immigrants. Our aim was to compare the serum 25-hydroxyvitamin D (25(OH)D) concentration of nonwestern immigrant populations with those of the population in their country of origin, and the indigenous population of the country they migrated to. METHODS: We performed literature searches in the "PubMed" and "Embase" databases, restricted to 1990 and later. The search profile consisted of terms referring to vitamin D or vitamin D deficiency, prevalence or cross-sectional studies, and countries or ethnicity. Titles and abstracts were reviewed to identify studies on population-based mean serum 25(OH)D concentrations among Turkish, Moroccan, Indian, and sub-Sahara African populations in Europe, Turkey, Morocco, India, and sub-Sahara Africa. RESULTS: The vitamin D status of immigrant populations in Europe was poor compared to the indigenous European populations. The vitamin D status of studied populations in Turkey and India varied and was either similar to the immigrant populations in Europe (low) or similar to or even higher than the indigenous European populations (high). CONCLUSIONS: In addition to observed negative consequences of low serum 25(OH)D concentrations among nonwestern populations, this overview indicates that vitamin D status in nonwestern immigrant populations should be improved. The most efficacious strategy should be the subject of further study.

Sunlight exposure or vitamin D supplementation for vitamin D-deficient non-western immigrants: a randomized clinical trial.

UNLABELLED: Vitamin D deficiency is very common in non-western immigrants. In this randomized clinical trial, vitamin D 800 IU/day or 100,000 IU/3 months were compared with advised sunlight exposure. Vitamin D supplementation was more effective than advised sunlight exposure in improving vitamin D status and lowering parathyroid hormone levels. INTRODUCTION: Vitamin D deficiency (25-hydroxyvitamin D [25(OH)D] < 25 nmol/l) is common among non-western immigrants. It can be treated with vitamin D supplementation or sunlight exposure. METHODS: To determine whether the effect of vitamin D(3) supplementation (daily 800 IU or 100,000 IU/3 months) or sunlight exposure advice is similar with regard to serum 25(OH)D and parathyroid hormone (PTH) concentrations. Randomized clinical trial in 11 general practices in The Netherlands. Non-western immigrants, aged 18-65 years (n = 232) and serum 25(OH)D < 25 nmol/l were randomly assigned to supplementation (daily 800 IU or 100,000 IU/3 months) or advice for sunlight exposure for 6 months (March-September). Blood samples were collected at baseline, during treatment (3 months, 6 months), and at follow-up (12 months). Statistical analysis was performed with multilevel regression modelling. RESULTS: The intention-to-treat analysis included 211 persons. Baseline serum 25(OH)D was 22.5 ± 11.1 nmol/l. After 6 months, mean serum 25(OH)D increased to 53 nmol/l with 800 IU/day, to 50.5 nmol/l with 100,000 IU/3 months, and to 29.1 nmol/l with advised sunlight exposure (supplementation vs sunshine p < 0.001). Serum PTH decreased significantly in all groups after 3 months, more in the supplementation groups than in the advised sunlight group (p < 0.05). There was no significant effect on physical performance and functional limitations. CONCLUSION: Vitamin D supplementation is more effective than advised sunlight exposure for treating vitamin D deficiency in non-western immigrants.

Human papillomavirus DNA testing for the detection of cervical intraepithelial neoplasia grade 3 and cancer: 5-year follow-up of a randomised controlled implementation trial.

BACKGROUND: Tests for the DNA of high-risk types of human papillomavirus (HPV) have a higher sensitivity for cervical intraepithelial neoplasia grade 3 or worse (CIN3+) than does cytological testing, but the necessity of such testing in cervical screening has been debated. Our aim was to determine whether the effectiveness of cervical screening improves when HPV DNA testing is implemented. METHODS: Women aged 29-56 years who were participating in the regular cervical screening programme in the Netherlands were randomly assigned to combined cytological and HPV DNA testing or to conventional cytological testing only. After 5 years, combined cytological and HPV DNA testing were done in both groups. The primary outcome measure was the number of CIN3+ lesions detected. Analyses were done by intention to treat. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN20781131. FINDINGS: 8575 women in the intervention group and 8580 in the control group were recruited, followed up for sufficient time (> or =6.5 years), and met eligibility criteria for our analyses. More CIN3+ lesions were detected at baseline in the intervention group than in the control group (68/8575 vs 40/8580, 70% increase, 95% CI 15-151; p=0.007). The number of CIN3+ lesions detected in the subsequent round was lower in the intervention group than in the control group (24/8413 vs 54/8456, 55% decrease, 95% CI 28-72; p=0.001). The number of CIN3+ lesions over the two rounds did not differ between groups. INTERPRETATION: The implementation of HPV DNA testing in cervical screening leads to earlier detection of CIN3+ lesions. Earlier detection of such lesions could permit an extension of the screening interval.

[Advisory report from the Health Council of the Netherlands to include human papillomavirus vaccination in the national immunisation programme for the prevention of cervical cancer]. / Advies van de Gezondheidsraad om vaccinatie tegen Humaan papillomavirus op te nemen in het Rijksvaccinatieprogramma om baarmoederhalskanker te voorkomen.

The Health Council of the Netherlands has advised the Minister of Health, Welfare and Sport to include vaccination against Human papillomavirus (HPV) for girls aged 12 years as part of the National Immunisation Programme. A catch-up vaccination is proposed for girls aged 13-16 years. High-risk HPV infections cause cervical cancer. Approximately 70% of these infections are attributed to HPV-16 and HPV-18. Vaccination was shown to prevent these infections and subsequent precursor lesions. Its efficacy in preventing cervical cancer has not yet been proven but is highly plausible. Protection lasts for more than so years. A booster may be needed after so years. The efficacy and safety of the two available vaccines are comparable. State-mandated vaccination is effective and ensures equal treatment regardless of economic status. Maintenance of the population screening programme for cervical cancer is important, and this must be communicated to the public properly. Careful monitoring is necessary for surveillance of effects, side effects, response rates and participation rates in cervical cancer screening. Guidelines are needed to aid physicians in determining whether to provide individual vaccination.

[Carotid calcification on a panoramic radiograph: what to do?]. / Een opaciteit in de hals op het orthopantomogram: wat te doen?

A 71-year-old man is discussed in whom the oral and maxillofacial surgeon observed, by chance, a radiopacity on the panoramic radiograph that was highly suggestive of a calcification at the bifurcation of the internal and external carotid artery. While, on the basis of international literature, various treatments are advanced with respect to the importance of vascular investigation and possible surgical removal of significant calcification, at present the view in The Netherlands is that the family doctor has the responsibility to assess whether such patient should be referred for further evaluation by the neurologist or vascular surgeon. The same applies to the possible indication for prescription of antitrombotics.

[Summary of the practice guideline 'Vaginal discharge' (first revision) from the Dutch College of General Practitioners]. / Samenvatting van de standaard 'Fluor vaginalis' (eerste herziening) van het Nederlands Huisartsen Genootschap.

The 1996 practice guideline of the Dutch College of General Practitioners (NHG) on vaginal discharge has been updated. Most women who visit their doctor with complaints about vaginal discharge do not have an increased risk of a sexually-transmitted disease. Investigations into vaginal discharge comprise history taking, physical examination and microscopic analysis in the laboratory of the general practitioner. Additional investigation into Chlamydia, gonorrhoea and Trichomonas infection is only necessary if the patient history reveals an increased risk of a sexually-transmitted disease. A Candida infection or bacterial vaginosis should only be treated if the patient experiences bothersome complaints. Treatment of a Candida infection consists of a vaginally applied imidazole compound. Bacterial vaginosis can be treated with oral administration of metronidazole. Patients with vaginal fluor can be examined and, if necessary, treated by their general practitioner. Referral to a gynaecologist is rarely necessary.

Implementation of human papillomavirus testing in cervical screening without a concomitant decrease in participation rate.

Adding high-risk human papillomavirus (hrHPV) testing to screening increases the efficacy of cervical screening programmes. However, hrHPV testing may result in a lower participation rate because of the perceived association with sexually transmitted infections. We describe how testing for hrHPV was added to cervical screening in the POpulation-BAsed SCreening study AMsterdam (POBASCAM) trial. Participation rates of the screening programme before and after hrHPV implementation were evaluated in the region where the POBASCAM trial was carried out. The participation rate was 58.7% before and 61.4% after the addition of hrHPV testing to screening (p<0.001). An inventory of frequently asked questions is presented. Thus, hrHPV testing can be added to cervical screening by cytology without a decrease in participation rate.

[The practice guideline 'Urinary-tract infections' (second revision) from the Dutch College of General Practitioners; a response from the perspective of general practice]. / De standaard 'Urineweginfecties' (tweede herziening) van het Nederlands Huisartsen Genootschap; reactie vanuit de huisartsgeneeskunde.

The Dutch College of General Practitioners recently published an update of the practice guideline on urinary-tract infections. This guideline provides a clear overview of the medical history, the diagnostic methods and the treatment options. Sixteen management modalities are presented in relation to specific patient characteristics. However, this revised guideline warrants some minor comments. According to the guideline, the dipstick (nitrite) test and dipslide form the two cornerstones of the diagnosis of urinary-tract infections. The value of the dipslide, however, seems to have been overestimated and that of microscopic examination of the urine by skilled physicians to have been underestimated. New in this guideline compared to that of 1999 is that nitrofurantoin (the treatment of first choice in uncomplicated infections) should be given for five instead of three days. The guideline motivates this change in policy on the basis of the numerous treatment failures seen in practice. The most convincing type of evidence, however, is not available due to the lack of relevant randomised clinical trials. The introduction of the prescription of phosphomycin, which is unusual in the Netherlands, as an alternative treatment for uncomplicated infections requires supportive evidence before it will be accepted by general practitioners. This well-documented guideline provides clear guidance for the general practitioner faced with patients with urinary-tract symptoms that could be caused by infection.

[Psychiatric manifestations due to abnormal glucocorticoid levels]. / Psychiatrische beelden bij afwijkende cortisolproductie.

This clinical case presentation describes the disease trajectory in two patients who presented with psychiatric symptoms as a result of abnormal serum glucocorticoid levels. One case involves a 58-year-old man with hypercortisolism, the other case concerns a 55-year-old woman with hypocortisolism. In both cases there was a considerable diagnostic delay in recognizing the underlying adrenal gland pathology. Abnormal glucocorticoid levels, caused by endocrine disorders, often results in psychiatric symptoms. Delay in diagnosis may have adverse consequences. Hyper- or hypocortisolism should be considered in patients who present with an atypical presentation of psychiatric symptoms. Moreover, the absence of specific physical signs or symptoms at first presentation in such patients does not exclude an underlying endocrinological cause. Therefore, physical and psychiatric reassessment of such patients should be considered at regular intervals.

[The risk of pelvic inflammatory disease associated with urogenital infection with Chlamydia trachomatis; literature review]. / De kans op 'pelvic inflammatory disease' bij urogenitale infectie met Chlamydia trachomatis; literatuuronderzoek.

OBJECTIVE: To determine the rate of PID in women with genital Chlamydia trachomatis infection. DESIGN: Systematic literature review. METHOD: MEDLINE and EMBASE were searched over the years 1975-2003 using the keywords 'Chlamydia trachomatis', 'complication', 'pelvic (inflammatory disease)', 'PID', 'endometritis', 'adnexitis', and 'salpingitis'. The reference lists ofthe articles retrieved were checked for other relevant publications. The PID complication rate was determined, as were the characteristics of the study populations and the validity of the diagnostic methods and outcome measures used. RESULTS: 9 prospective studies were identified. The rate of PID in women with a genital C. trachomatis infection varied between o and 72%. Asymptomatic women who were diagnosed with C. trachomatis infection in general screening had the lowest rate of PID: 0-4%. PID occurred in 12-30% of symptomatic women or women with a higher risk of having an STD (e.g. visitor of an STD clinic, double-infection with gonorrhoea, high risk assessed by questionnaire, having a partner with symptomatic C. trachomatis infection). Women who underwent legal abortion had the highest rate of PID (27-72%). CONCLUSION: The PID rate in women with C. trachomatis varied considerably. Risk depended on whether the infection was symptomatic and the prior probability of having an STD.

Incidence and management of oral conditions in general practice.

Despite a high community prevalence, little is known about the occurrence of oral conditions in general practice. In an observational study, 354 new cases of oral complaints were recorded in 35 participating practices during a period of six months (cumulative incidence = 6.7 per 1000 per year). The incidence was highest in children under five years of age (21% of all cases). The conditions diagnosed most frequently were aphthous ulceration, oral candidiasis, and herpes simplex infection. Most oral conditions were minor ailments, and could be dealt with by the general practitioner alone.

[Dutch Institute for Health Care Improvement revised guideline, 'Sexually transmitted diseases and neonatal herpes']. / CBO-richtlijn 'seksueel overdraagbare aandoeningen en herpes neonatorum' (herziening).

The Dutch Institute for Health Care Improvement revised guideline, 'Sexually transmitted diseases and neonatal herpes' summarises the current scientific position on the diagnosis and treatment of a great number of sexually transmitted diseases (STD) and neonatal herpes. Symptomatic treatment of suspected Chlamydia trachomatis infection and gonorrhoea without previous diagnosis is not recommended. Treatment can be started immediately, once samples have been taken. Risk groups eligible for screening or proactive testing on C. trachomatis infection include: partners of C. trachomatis-positive persons, visitors of STD clinics, women who will undergo an abortion, mothers of newborns with conjunctivitis or pneumonitis, young persons of Surinam or Antillean descent, young women with new relationships and individuals whose history indicates risky sexual behaviour. A period of 3 months can be adopted between a risky contact and the HIV test (this used to be 6 months), unless post-exposure prophylaxis was used. For the treatment of early syphilis no distinction is drawn between HIV-infected and non-HIV-infected persons. It is no longer recommended that women in labour with a history of genital herpes are tested for the herpes simplex virus. Virological testing of the neonate is only advised if the mother shows signs of genital herpes during delivery.

[Summary of the NHG guideline 'The STD consultation']. / Samenvatting van de NHG-standaard 'Het soa-consult'.

The guideline 'The STD consultation' of the Dutch College of General Practitioners provides guidelines for the diagnosis and management of patients with symptoms of a sexually transmitted disease (STD), patients at high risk of being infected with a STD (risk groups), and patients with questions or concerns about STDs. The test policy depends on the patient's symptoms and risks and is extensively described in the guideline. Men who have sex with men (MSM), prostitutes, people who visit prostitutes, people from countries in which STDs are endemic, people with multiple sexual partners, and people with a partner from one of these groups are at increased risk of contracting one of the five major STDs (chlamydia, gonorrhoea, syphilis, hepatitis B, and HIV). Patients originating from HIV-endemic regions or MSM can be offered HIV and, if appropriate, hepatitis B testing. Young men and women (< 25 years) can be offered chlamydia testing.- Treatment is dependent on the causative agent.

[Pre-exposure prophylaxis for HIV transmission? No, unless]. / Pre-expositieprofylaxe van hiv-infectie? Nee, tenzij.

Pre-exposure prophylaxis (PrEP) with tenofovir/emtricitabine (TDF/FTC) will soon be available in the Netherlands. Moderate evidence concerning practical efficacy, small absolute risk reduction (1-2%) and a high number needed to treat (50-75) are key figures. Prevention of one HIV infection will cost EUR 350,000 to 500,000. No information is available on long-term renal function and antiretroviral resistance. Guidelines are needed before treatment with PrEP is introduced in the Netherlands.

[Summary of the practice guideline for shoulder complaints from the Dutch College of General Practitioners]. / Samenvatting van de standaard 'Schouderklachten' van het Nederlands Huisartsen Genootschap.

The second revision of the practice guideline for shoulder complaints was presented in 2008 by the Dutch College of General Practitioners. This guideline provides a standard for the diagnosis and treatment of shoulder complaints by general practitioners. The most important items in this new guideline are reviewed.
