- The aim of this study was to estimate the annual burden of fungal infections in Sweden using data mainly from 2016. Data on specific populations were obtained from Swedish national data registries. Annual incidence and prevalence of fungal disease was calculated based on epidemiological studies. Data on infections due to Cryptococcus sp., Mucorales, Histoplasma capsulatum, Coccidioides immitis and Pneumocystis jirovecii were retrieved from Karolinska University Laboratory and covers only 25% of Swedish population. In 2016, the population of Sweden was 9 995 153 (49.8% female). The overall burden of fungal infections was 1 713 385 (17 142/100 000). Superficial fungal infections affect 1 429 307 people (1429/100 000) based on Global Burden of Disease 14.3% prevalence. Total serious fungal infection burden was 284 174 (2843/100 000) in 2016. Recurrent Candida vulvovaginitis is common; assuming a 6% prevalence in women. Prevalence of allergic bronchopulmonary aspergillosis and severe asthma with fungal sensitisation were estimated to be 20 095 and 26 387, respectively. Similarly, chronic pulmonary aspergillosis was estimated to affect 490 patients after tuberculosis, sarcoidosis and other conditions. Candidemia incidence was estimated to be 500 in 2016 (4.7/100 000) and invasive aspergillosis 295 (3.0/100 000). In Stockholm area, Mucorales were reported in three patients in 2015, while Cryptococcus spp. were reported in two patients. In 2016, there were 297 patients PCR positive for P jirovecii. The present study shows that the overall burden of fungal infections in Sweden is high and affects 17% of the population. The morbidity, mortality and the healthcare‐related costs due to fungal infections warrant further studies.

- Introduction: --- Aurantiasis cutis is a condition of yellowish or golden skin discoloration that can result from eating excessive amounts of foods containing carotene leading to hypercarotenemia(1), described causing secondary amenorrhea(2). Objective & hypothesis: --- Hypercarotenemia can cause secondary amenorrhea without overconsumption of excessive quantities of carotene. Results: --- Laboratory tests showed a ß-Carotene level more than the 2-fold above the upper reference level. Hyperbilirubinemia could be excluded. Hypogonadotropic hypogonadism was not present. There was no evidence for adrenal dysfunction. Liver function tests were normal. Material/ Methods: --- A 16-year-old girl presented to our endocrine outpatient clinic with a 2-year history of varying yellow discoloration of her skin and secondary amenorrhea. The findings of the general physical examination were normal, but there was a marked yellow discoloration of the palms, soles, and nasolabial folds. A dietary history revealed a low carotene diet, but also a low carbohydrate diet. BMI was 19.9 kg/m² (-0.2 SDS) without signs of anorexia. Discussion: --- In this girl we observed hypercarotenemia associated with secondary nonhypothalamic amenorrhea in absence of excess external intake of carotenes. This suggests an intrinsic reason due to a polymorphism(3) in ß-carotene 15,15'-monooxygenase (BCO)(4), an enzyme breaking down carotenes to vitamin A(5). Phenotype-genotype association studies are needed to confirm this hypothesis. Conclusion: --- Secondary non-hypothalamic amenorrhea can be associated with hypercarotenemia. References: --- 1.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to describe and compare the knowledge of registered nurses (RNs), assistant nurses (ANs) and student nurses (SNs) about preventing pressure ulcers (PUs). PU prevention behaviours in the clinical practice of RNs and ANs were also explored. A descriptive, comparative multicentre study was performed. Hospital wards and universities from four Swedish county councils participated. In total, 415 participants (RN, AN and SN) completed the Pressure Ulcer Knowledge Assessment Tool. The mean knowledge score for the sample was 58·9%. The highest scores were found in the themes 'nutrition' (83·1%) and 'risk assessment' (75·7%). The lowest scores were found in the themes 'reduction in the amount of pressure and shear' (47·5%) and 'classification and observation' (55·5%). RNs and SNs had higher scores than ANs on 'aetiology and causes'. SNs had higher scores than RNs and ANs on 'nutrition'. It has been concluded that there is a knowledge deficit in PU prevention among nursing staff in Sweden. A major educational campaign needs to be undertaken both in hospital settings and in nursing education.

Imaging mass spectrometry for novel insights into contact allergy - a proof-of-concept study on nickel
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Background. In spite of extensive regulation to limit exposure, nickel remains the main cause of contact allergy in the general population. More detailed knowledge on the skin uptake of haptens is required. So far, no method exists for the visualization of this clinically relevant hapten and its distribution in the skin. Objectives. To show, in terms of a proof of concept, that imaging mass spectrometry [time of flight secondary ion mass spectrometry (ToF-SIMS)] can be applied for investigation of the penetration and distribution of nickel in human skin. Method. Full-thickness human skin obtained from breast reduction surgery was exposed to nickel sulfate (5% in deionized water) for 24 h in Franz-type diffusion cells. Biopsies were obtained from nickel-treated samples and control (deionized water). The tissue was sliced, and analysed with ToF-SIMS, generating high-resolution images of ion distribution in the epidermis and upper dermis. Results. The skin layers could be discerned from the ToF-SIMS data, particularly on the basis of the collagen signal. Nickel ions were localized to the stratum corneum and upper epidermis. Conclusions. This is the first time that ToF-SIMS has been applied to trace the distribution of a hapten in human skin. Proof of principle was shown for nickel, and the technique can, in the future, be expanded for investigation of the skin distribution of clinically relevant sensitizers in general.

Tidskriftsartikel (refereegranskat)abstract
- This Swedish register-based cohort study examined whether asthma, hay fever and allergic dermatitis in late adolescence identified in the early 1970s are associated with antidepressant medication in middle age, between 2006 and 2009. After adjustment for childhood and adulthood sociodemographic characteristics, psychological, cognitive and physical function, and comorbidity, the magnitude of the associations diminished for asthma, while hay fever and atopic dermatitis retained associations. Hay fever and atopic dermatitis in adolescence have potentially important implications for future mental health, while asthma may already have influenced an individual's ability to cope with stress by late adolescence.

Individualized treatment for ovarian cancer may become possible
- 2015

Ingår i: Läkartidningen. - 0023-7205. ; 112

Tidskriftsartikel (refereegranskat)abstract
- Epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy in developed countries. Several promising steps toward individualized therapy have been taken recently due to increased knowledge of molecular biology. Multidisciplinary conferences for treatment planning and the centralization to tertiary surgical centers improve quality of surgery and survival. The primary treatment of EOC is radical surgery followed by adjuvant chemotherapy with carboplatin and paclitaxel. Bevacizumab added to the chemotherapy and used as maintenance treatment is standard in the primary treatment of patients with residual tumor or inoperable patients. The PARP inhibitor olaparib is recommended as maintenance treatment of women with platinum sensitive relapsed BRCA mutated high-grade serous EOC who have responded to platinum-based chemotherapy. BRCA testing should be offered to women with EOC. In platinum-resistant recurrence addition of bevacizumab to chemotherapy should be considered.

Genetic testing and surveillance guidelines in hereditary pheochromocytoma and paraganglioma
- 2019
-
Ingår i: Journal of Internal Medicine. - : Wiley. - 0954-6820 .- 1365-2796. ; 285:2, s. 187-204

Tidskriftsartikel (refereegranskat)abstract
- Pheochromocytoma and paraganglioma (PPGL) are rare tumours and at least 30% are part of hereditary syndromes. Approximately 20% of hereditary PPGL are caused by pathogenic germ line variants in genes of the succinate dehydrogenase complex (SDHx), TMEM127 or MAX. Herein we present guidelines regarding genetic testing of family members and their surveillance based on a thorough literature review. All cases of PPGL are recommended genetic testing for germ line variants regardless of patient and family characteristics. At minimum, FH, NF1, RET, SDHB, SDHD and VHL should be tested. In addition, testing of MEN1, SDHA, SDHAF2, SDHC, TMEM127 and MAX is recommended. Healthy first-degree relatives (and second-degree relatives in the case of SDHD and SDHAF2 which are maternally imprinted) should be offered carrier testing. Carriers of pathogenic variants should be offered surveillance with annual biochemical measurements of methoxy-catecholamines and bi-annual rapid whole-body magnetic resonance imaging and clinical examination. Surveillance should start 5 years before the earliest age of onset in the family and thus only children eligible for surveillance should be offered pre-symptomatic genetic testing. The surveillance of children younger than 15 years needs to be individually designed. Our guidelines will provide a framework for patient management with the possibility to follow outcome via national registries and/or follow-up studies. Together with improved insights into the disease, this may enable optimisation of the surveillance scheme in order to minimise both anxiety and medical complications while ensuring early disease detection.
