Treatment of keratoconjunctivitis sicca with topical androgen

Objective: Androgens have been reported to influence lipid production of sebaceous glands and even many ocular tissues. The effect of topical androgen therapy on a 54-year-old patient with keratoconjunctivitis sicca (KCS) and decreased lipid phase of the tear film is reported. Methods: For assessment of the lipid phase of the tear film, break up time (BUT) and lipid layer thickness (LLT) were monitored during 6 months before treatment as well as 3 months while using a daily topical androgen therapy. Results: During the topical androgen therapy the pathological lipid phase of the tear film was completely restored indicated by the normalisation of the values of BUT and LLT. Conclusion: These findings are consistent with animal experiments indicating that topical administered androgen can restore the decreased lipid phase of the tear film. This may open up new therapeutic strategies for KCS.     

Endometrial volume change during spontaneous menstrual cycles: volumetry by transvaginal three-dimensional ultrasound

Objective: At present, only limited data are available on endometrial volume during the menstrual cycle. Most of these studies deal with animal models and use magnetic resonance imaging for volume measuring. The application of three-dimensional ultrasound in endometrial volume estimation is the subject of this study.Setting: Patients visiting the outpatient unit of the division of endocrinology and reproductive medicine of a university hospital.Patient(s): Twenty patients with a history of a normal menstrual cycle were selected.Intervention(s): Ultrasound examinations were performed during a single menstrual cycle in addition to routine laboratory tests.Main Outcome Measure(s): Uterus-endometrial volume ratio.Result(s): Data from 18 patients could be evaluated. In 81 examinations the endometrium volume could be determined. Mean endometrial volume measured by three-dimensional ultrasound was 1.23 cm'. Mean uterus volume was 48.93 cm3. The change of the uterus-endometrial volume ratio showed a good correlation with the day of menstrual cycle. Quadratic regression analysis of volume and cycle length was R² = 0.432.Conclusion(s): Three-dimensional ultrasound allows assessment of volume data of the female internal genitalia. In this study changes of the endometrial volume in menstrual cycles were measured. Additional studies are required to give information on the clinical impact of this new technique of endometrial volume estimation.     

EuroGuiDerm Guideline on the systemic treatment of Psoriasis vulgaris – Part 1: treatment and monitoring recommendations

This evidence- and consensus-based guideline on the treatment of psoriasis vulgaris was developed following the EuroGuiDerm Guideline and Consensus Statement Development Manual. The first part of the guideline includes general information on the scope and purpose, health questions covered, target users and strength/limitations of the guideline. Suggestions for disease severity grading and treatment goals are provided. It presents the general treatment recommendations as well as detailed management and monitoring recommendations for the individual drugs. The treatment options discussed in this guideline are as follows: acitretin, ciclosporin, fumarates, methotrexate, adalimumab, apremilast, brodalumab, certolizumab pegol, etanercept, guselkumab, infliximab, ixekizumab, risankizumab, secukinumab, tildrakizumab and ustekinumab.     

Body Mass Index,Follicle-Stimulating Hormone and Their Predictive Value in In Vitro Fertilization

Purpose: The objective was to explore whether body mass and day 3 follicle-stimulating hormone have predictive value on odds of pregnancy after in vitro fertilisation. Few studies show that obesity produces a variety of alterations in the reproductive system, and that women with an elevation of day 3 FSH have declining ovarian function.Methods: The data of one-hundred-seventy-one women who underwent a standard regime of controlled ovarian hyperstimulation was analyzed with particular reference to variations in body mass and hormone levels.Results: By raising BMI and FSH (mIU/mL) by one unit, the odds for pregnancy were decreased by the respective factors 0.84 (95% confidence interval 0.73–0.97) and 0.77 (95% confidence interval 0.59–1.00).Conclusions: The results demonstrate that for the purpose of raising the odds of pregnancy BMI should be reduced. A low FSH value may cause the same effect. Nontheless, obesity and hormonal function may be independent risk factors for failure in assisted reproduction.     

Severe 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) intoxication: clinical and laboratory effects

A variety of health effects have been attributed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), but little information is available on the course of a verified high-level TCDD intoxication. In this paper we describe two cases of heavy intoxication with TCDD and present a 2-year follow-up including clinical, biochemical, hematologic, endocrine, and immunologic parameters monitored in two women, 30 and 27 years of age, who suffered from chloracne due to TCDD intoxication of unknown origin. Patient 1, who had the highest TCDD level ever recorded in an individual (144,000 pg/g blood fat), developed severe generalized chloracne, whereas in the second patient, despite heavy intoxication (26,000 pg/g blood fat), only mild facial acne lesions occurred. Both patients initially experienced nonspecific gastrointestinal symptoms. In Patient 1 we observed a moderate elevation of blood lipids, leukocytosis, anemia, and secondary amenorrhoea. The laboratory parameters in Patient 2 were all normal. Despite the high TCDD levels, apart from chloracne, only few clinical and biochemical health effects were observed within the first 2 years after TCDD intoxication.     

Serum levels of progesterone in patients with preeclampsia

In a matched pair-study study we investigated the hitherto controversially discussed serum levels of progesterone in 40 women with severe preeclampsia (PE) and 40 normotensive controls. Serum levels were determined by applying a sandwich enzyme-linked immunosorbent assay (ELISA). Median serum levels of progesterone in preeclamptic women and in controls were not statistically significant (P = 0.73). Our study indicates that the absence of altered serum levels of progesterone may not reflect the potential role of this hormone in preeclampsia.     

Expression of inducible nitric oxide synthase in human breast cancer depends on tumor grade

Expression of inducible nitric oxide synthase (iNOS) by tumor cells has been suggested to abrogate metastasis in several tumor models, whereas constitutive NOS expression correlated positively with tumor grade in human breast carcinoma. Whether or not expression of one of the various NOS isoforms could predict the prognosis of breast cancer, however, has not been established. In the present report we investigated the cellular distribution of NOS isoforms in a series of benign and malignant breast tumors and in normal breast tissue. Immunohistochemistry revealed that in samples of benign disease the number of iNOS+epithelial cells or total epithelial cells was 69±16% (n=50). In samples of grade II invasive ductal breast carcinomas the number of iNOS+ tumor cells or total tumor cells was 62±20 (n=40), compared to 12±9 (n=40) in samples of grade III carcinomas (P<0.0001). iNOS protein was also identifiable in most of the epithelial cells of normal breast tissue (n=4). In contrast, eNOS protein was restricted to vascular endothelial cells in all of the specimens studied. Since the presence of tumor cell iNOS protein is inversely related to the tumors metastatic potential, we conclude that endogenous tumor cell mediated iNOS expression might have an inhibitory effect on the metastatic process in breast cancer.     

G(-699)/C polymorphism in the bradykinin-1 receptor gene in patients with renal failure.

BACKGROUND: Bradykinin is thought to have protective effects on the progression of renal failure. Of particular interest, it has been reported that one polymorphism in the promoter region of the human kinin B1-receptor gene which is associated with higher activity, is less frequently found in patients with end-stage renal failure. The present study was performed to independently confirm these results. DESIGN: Cross-sectional study on 376 healthy controls, 262 non-diabetic dialysis patients and 175 patients with type 1 diabetes >/=10 years and microalbuminuria (of whom 21 were dialysis-dependent) and 334 patients with type 2 diabetes >/=10 years and nephropathy (of whom 61 were dialysis-dependent). METHODS: Genotyping was performed by polymerase chain reaction, followed by restriction enzyme analysis. RESULTS: All groups were in Hardy Weinberg equilibrium. The study showed no significant difference in the frequency of the C-allele between controls (0.093) and non-diabetic dialysis patients (0.095). No significant difference in C-allele frequency was observed between controls and patients with type 1 diabetes and microalbuminuria (0.092) or patients with type 2 diabetes and nephropathy (0.099). CONCLUSION: In large cohorts of patients with non-diabetic end-stage renal disease and diabetic renal disease with and without end-stage renal failure, no change in the frequency of the C-699 allele of the B-1-receptor gene was found.
