Toxic epidermal necrolysis in patient with malignant astrocytoma.

UNLABELLED: Toxic epidermal necrolysis (TEN) is a severe, life-threatening mucocutaneus adverse reaction, most commonly triggered by medication. Treatment in some aspects is still controversial. CASE REPORT: Patient with malignant astrocytoma, treated with palliative radiotherapy, developed massive erythema with bullae. Patient suffered from tumor-related epilepsy, treated pharmacologically with carbamazepine. After dermatological consultation TEN was diagnosed. The bacterial growth tests from blood were Staphylococci positive. An antibiotic therapy was performed and carbamazepine was withdrawn. Cyclosporine was administered. After 2 weeks of treatment, skin changes vanished and patient's condition improved. TEN could not be omitted in diagnosis of extensive skin changes because the causative drug removal is crucial for survival and pharmacological treatment varies in similar conditions. TEN as a drug-related disease more likely occurs in severely ill patients.

The morning and late-night salivary cortisol ranges for healthy women may be used in pregnancy.

OBJECTIVES: The diagnosis of adrenal dysfunction in pregnancy and in women taking oral contraceptives remains a diagnostic challenge. Salivary cortisol seems to be a useful tool for the diagnosis of Cushing's syndrome and adrenal insufficiency. However, the changes in salivary cortisol concentration in healthy pregnancy are not clearly defined. DESIGN: The aim of our study was to compare diurnal changes in salivary cortisol in healthy pregnant women, healthy controls and women on oral contraceptives. PATIENTS: The study groups consisted of (i) 41 healthy pregnant women, (ii) 42 healthy women and (iii) 12 healthy women on oral contraceptives. MEASUREMENTS: Serum and salivary cortisol in the morning and salivary late-night cortisol were measured with Roche ECLIA cortisol test (Elecsys 2010) in each trimester and postpartum. RESULTS: Despite the elevation of morning serum cortisol in the second and third trimesters of pregnancy, the morning salivary values as well as late-night salivary cortisol throughout all trimesters were not significantly different from control values (P > 0·5). In the postpartum period, the morning and late-night salivary cortisol values were significantly lower than in late pregnancy. The morning and late-night salivary cortisol values in women on contraceptives were also not different from those in the healthy women group. CONCLUSION: The results of our study suggest that reference values for salivary cortisol established for a healthy adult population can be used for pregnant women and women on oral contraceptives in the initial diagnostic testing for Cushing's syndrome and adrenal insufficiency.

Vitamin D insufficiency in healthy pregnant women living in Warsaw.

BACKGROUND/OBJECTIVES: Ensuring the optimal level of 25-hydroxy-vitamin D (250HD) in serum (concentration above 30 ng/ml) is essential for protecting the health of the mother and the developing fetus. Vitamin D plays an important role in maintaining proper bone structure, preventing infections, reducing the risk of premature birth and gestational diabetes. The aim of the study was to verify whether healthy pregnant residents of Warsaw were deficient in vitamin D. MATERIAL AND METHODS: The material consisted of 150 serum samples of 50 healthy women in 1st, 2nd and 3rd trimester of pregnancy 72.7% of the sera were from women who reported taking multivitamin supplements containing vitamin D3 (71% out of that group was taking 400 IU daily). The concentration of 250HD was measured using the vitamin D total assay on Elecsys 2010 automatic analyzer (Roche Diagnostics). RESULTS: The average serum 250HD concentrations of 50 women in 1st, 2nd and 3rd trimester of pregnancy were respectively: 23.1 ng/ml, 24.8 ng/ml, and 25.1 ng/ml, with no statistically significant differences. The optimal levels of 250HD (30-80 ng/ml) were found in 30.0% of samples, hypovitaminosis (20-30 ng/ml) occurred in 38.7%, deficiency (10-20 ng/ml) in 24.0% and severe deficiency (less than 10 ng/ml) in 7.3% of cases. Mean concentration of 250HD in winter season (October 1 - March 31) was 23.6 ng/ml and in summer season (April 1 - September 30) was 25.5 ng/ml, with no statistically significant difference. On the basis of the BMI in 1st trimester two subgroups were distinguished from the studied subjects: BMI <21 (13 patients, 39 samples) and BMI >25 (14 patients, 42 samples). Mean 250HD concentration in these groups were 27.3 and 23.5 ng/ml respectively (p<0.05). High statistical significance (p<0.001) was found among the total number of samples with 250HD deficiency and severe deficiency (<20 ng/ml) and samples with hypovitaminosis and optimal 250HD level (>20 ng/ml) in these groups. CONCLUSIONS: Regardless of trimester and season, vitamin D below the optimal level is a common occurrence during pregnancy and the current level of supplementation among Polish pregnant women appears to be insufficient. Our data suggest that special attention should be paid to the problem of vitamin D insufficiency in overweight pregnant women.

[Iodine supply and thyroid function in the group of healthy pregnant women living in Warsaw]. / Zaopatrzenie wjod oraz czynnosc tarczycy w grupie zdrowych kobiet ciezarnych zamieszkujacych Warszawe.

UNLABELLED: Iodine deficiency and thyroid gland disorders are especially harmful for pregnant women and normal fetal development. After initiation in 1997 of obligatory iodine prophylaxis, Poland has been found since 2003 a country with sufficient delivery of this microelement. However, in the population of pregnant women, slight deficiency of this element still exists. Insufficient iodine supply results in abnormalities of thyroid hormones'biosynthesis. Simultaneously, adaptive changes, occurring in pregnancy, make the proper interpretation of hormone's assays difficult. Lack of normative data for the thyroid hormones concentration in the each pregnancy trimester for Polish population cause additional difficulties in the interpretation of these results. The aim of the study was prospective observation of iodine intake and thyroid function in healthy pregnant women supplemented with 150 pg of iodine daily MATERIALS AND METHODS: 62 healthy pregnant women living in Warsaw in the early weeks of pregnancy, confirmed by ultrasonographic examination, were included to this study. Pregnancies were singleton resulting in birth of healthy neonates. Urinary iodine concentrations (UIC), serum TSH, fT4, fT3, antyTPO, thyroid volume and morphology by the ultrasonography examination were assessed in consecutive trimesters of pregnancy. TSH level was measured in the each newborn. RESULTS: Low urinary iodine concentrations (UIC)-median 96 microg/l was found at the beginning of pregnancy Only in 14% of pregnant women UIC exceeded 150 microg/l. In spite of intended supplementation of at least 150 microg of extra iodine per day, medians of UIC in the next trimesters were 122 microg/l and 129 microg/l, respectively. TSH levels kept reference values for the 1st trimester of pregnancy in 86% of participants and in the next trimesters in 85% and 95%, respectively. Levels of fT4 were within reference range for the women in the 1st trimester. In 2nd trimester 12% and in 3rd trimester 33% of pregnant women had fT4 level below the reference value. Concentrations of fT3 were within reference values during whole pregnancy. Median thyroid volume was respectively 11.12 ml; 13.0 ml and 15.75 ml (range: 6.8-26.8 ml) in subsequent trimesters.Median neonatal' TSH level on the 3rd day of life, as a screening of thyroid insufficiency, was 1.34 mlU/l (range: 0.01-6.6 mlU/l) and in 4.41 % of newborns TSH concentrations were higher than 5 mlU/I. CONCLUSION: Despite the sufficient supply of iodine in the whole population, iodine consumption among the pregnant women is still not satisfactory. The increase of TSH values above the upper reference level for pregnant women in 15% of patients may be related to iodine deficiency. It is important to educate pregnancy planning women about this problem. Our observations confirm the importance of the recommendations that during the pregnancy every woman should receive supplementation of iodine at the minimal amount of 150 microg daily.

Severe selenium deficits in pregnant women irrespective of autoimmune thyroid disease in an area with marginal selenium intake.

OBJECTIVES: Selenium (Se) deficiency is related to an increased risk of preterm labor, miscarriage, preeclampsia, gestational diabetes, and other obstetric complications. As the Se status declines during pregnancy, we hypothesized that the decline may be exacerbated in women with autoimmune thyroid disease (AITD). MATERIAL AND METHODS: Pregnant women (n=74; 30 [23-38] years) were consecutively recruited from the district of Warsaw, Poland, and divided into healthy subjects (HS, n=45), and women with a diagnosis of AITD (AITD, n=29). Thyroglobulin antibodies (TG-aAb), thyroid peroxidase antibodies (TPO-aAb), TSH, free T3, free T4, total T3, and total T4, as well as urine iodine excretion were determined. Se status was assessed by serum Se and selenoprotein P (SELENOP) concentrations. Thyroid volume was evaluated by ultrasonography. RESULTS: Serum Se and SELENOP concentrations were relatively low in both control and AITD women. A Se deficit according to WHO definition (<45µg/l) was observed in 0%, 3.4%, 28.6% and 4.5%, 18.2%, 35.5% of women in the AITD and HS group, respectively, during the 1st, 2nd, and 3rd trimester. From first to third trimester, TPO-aAb and TG-aAb declined in AITD by 71% and 60%, respectively. The decline in TPO- and TG-aAb was unrelated to the Se status. CONCLUSIONS: In this area of habitual low Se intake, a high proportion of women developed a severe Se deficit during pregnancy, irrespective of AITD status. This decline must be considered as a preventable risk factor for pregnancy complications of relevance to both the unborn child and the pregnant mother.
