The common femoral artery is a widely used for access in endovascular interventions. Various complications, such as hematoma, pseudoaneurysm and AV-fistula (AVF), can arise from arterial punctures with estimated prevalence between 1-10%. AVF is a rare complication with prevalence p<1%. AVF can cause a hemodynamic change in the form of a arteriovenous shunt (AV-shunt). AV-shunts in the groin are usually small and asymptomatic but tend to be symptomatic with larger and persistent AVFs which can present with leg claudication or high outpute heart failure.

Introduction: To limit exposure to methylmercury several countries have implimented specific advice on fish intake to pregnant women as well a measuring compliance through regular human biomonitoring. Despite fish intake being relatively high in Iceland, human biomonitoring data on mercury is scarce.

Materials and mehods: We measured mercury in hair from 120 pregnant women recruited in 2021 from the the Reykjavik Capital area. At recruitment, information on fish intake during the past four months was recorded. Hair mercury concentrations were compared to existing health based guidance values and associatons with fish intake was explored.

Results: Mean (standard deviation) mercury concentration in hair was 0.48 μg/g (0.33). All participants had concentrations in hair below 1.8 μg/g, which corresponds to the hair value that the tolerable daily intake set by the European Food Safety Authority is derived from, while 5% had concentrations above 1.1 μg/g, which corresponds to the hair value that the US-EPA reference dose is derived from. Mean mercury concentrations in hair increased in a dose dependent manner (p for trend p<0.001) from 0.25 μg/g among women who consumed fish ≤ 3/month (n=24) and up to 0.80 mg/g among those consuming fish 3-4/ week (n=16). The few (n=3) women who reported to have eaten shark (p<1/month) were all at the higher end of the exposure distribution.

Conclusion: Our results suggest that exposure is generally below the tolerable daily intake set by EFSA but may in some women exceed the reference dose established by the US-EPA.

Introduction: Maternal deaths are rare and an indirect measure of the societal framework surrounding pregnancy and childbirth. We surveyed and classified maternal mortality in Iceland using international guidelines, calculating changes over a 40-year period.

Material and methods: Information from Statistics Iceland on women aged 15-49 years who died in 1985-2015 were cross-checked against birth registration and hospital admission data to identify women who died in pregnancy or ≤42 and within 43-365 days from birth or termination of a pregnancy. Data for 1976-1984 were searched manually. Case records and autopsy reports were scrutinized. Deaths were classified as direct, indirect or coincidental and as early or late.

Results: Among 1600 women 48 died in pregnancy or within a year after pregnancy. Births totaled 172369 and overall maternal mortality was 27.8/100.000 births. Maternal mortality by World Health Organization criteria (direct/indirect ≤42 days) occurred in 14 instances giving a maternal mortality ratio (MMR) of 8.1/100.000. Rates lowered between the first and last 10-year periods, particularly initially followed by a lesser downward trend. Direct deaths were 6, indirect 20, coincidental 22 (accidents, diseases). Causes of direct deaths were severe preeclampsia, pulmonary embolism and choriocarcinoma. Underlying causes of indirect deaths included cancer, diabetes, brain/heart conditions and suicide. No deaths occurred from ectopic pregnancy, hemorrhage or anesthesia.

Conclusions: Maternal mortality in Iceland is among the lowest reported. Women died because of the pregnancy, from worsening of underlying conditions or coincidentally. Risk groups require better support. Continued attention to adverse health connected to maternity is essential.

We report a case of a man with a 30-year history of treatment-resistant hypertension, hydropoiesis, tachycardic spells and dysgeusia. Despite repeated visits to the emergency department and work-up in an out-patient clinic, the diagnosis was unknown. Three years prior to remittance to an endocrinologist, the hypertension worsened, and he developed diabetes type-II. Further work-up revealed a 3 cm extra-adrenal pheochromocytoma, a paraganglioma. After surgical removal of the tumor, he is without medication and symptom free. Pheochromocytoma and paraganglioma are rare causes of hypertension, estimated to explain 0.1-0.6% of all cases, but nonetheless an important diagnosis to make, due to serious side effects.

Introduction: Chronic pain is a health problem that is one of leading cause of disability. Studies have shown that various aspects of a person's history, such as difficult experiences in early life, can affect lifestyle and health later. The aim of this study was to examine the relationship between chronic pain, adverse childhood experience (ACE) and violence in adulthood in the general population of Iceland.  MATERIAL AND METHODS: A retrospective cross-sectional study. The sample was 12.400 individuals, 18-80 years of age, randomly selected from respondents' group of the data collection company MASKINA (National Portal). Data on chronic pain, ACE and experience of violence in adulthood were examined. Statistical processing was carried out in IBM SPSS Statistics 28th edition.  RESULTS: Response rate was 44.8% (female 57.1%, M=56 years). Prevalence of chronic pain (≥3 months) was 40.1%. A total of 91.1% of participants answered questions about ACE, of which 16.1% ≥4 ACE-scores. There was a positive relationship between ACE and chronic pain (OR = 1.675, 95% CI: 1.420 - 1.977). Those who had ≥4 ACE-scores were more likely to have experienced violence in adulthood.  CSONCLUSION: The results of this study show that chronic pain and violence in adulthood can be associated with psychological childhood trauma. People who experience psychological childhood trauma and violence in adulthood are more likely to suffer from chronic pain. It is important to be aware of experiences of childhood psychological trauma and violence when people seek healthcare for chronic pain.

Introduction: Insufficient iodine status was recently identified in pregnant women in Iceland. Iodine fortification of salt is widely used to decrease the risk of iodine deficiency disorders, but the use of iodized salt has not been recommended in Iceland. The aim was to describe iodine intake among Icelandic adults and two-year-olds and estimate the effect of using iodized salt in bread.

Material and methods: Iodine intake was assessed using data from the Icelandic National Dietary Survey 2019-2021 (18-80 years, n=822) and a study of two-year-old children (n=124). Data on bread intake was used to estimate expected iodine intake if iodized salt was used in bread. The results are compared with recommended iodine intake (90 µg/day for two-year-olds and 150 µg/day for adults) and upper intake level (200 µg/day and 600 µg/day, respectively).

Results: Average iodine intake was 88 µg/day for children and 134 µg/day for adults. If all types of bread consumed would contain 20 µg of iodine in 100 grams, the average iodine intake would increase to 99 and 153 µg/day, respectively. With higher bread iodine content, >5% of two-year-olds would exceed the upper intake level, while concentration up to 70 µg/100 grams of bread would result in iodine intake below the upper intake level for adults.

Conclusion: Use of iodized salt in bread corresponding to 20µg of iodine in 100 grams of bread seems safe for young children in Iceland. However, based on the current dietary habits, adding this amount of iodine to bread would not be sufficient to secure optimal intake of iodine in all adults.
