Plasma kisspeptin levels in pregnancies with diabetes and hypertensive disease as a potential marker of placental dysfunction and adverse perinatal outcome.

BACKGROUND: The aim of this study was to prospectively evaluate plasma kisspeptin levels in 129 singleton pregnancies with diabetes [pregestational insulin-dependent diabetes mellitus (type 1) and gestational diabetes (GD)] and hypertensive disease [chronic hypertension (CH), gestational hypertension, and preeclampsia (PE)] as a potential marker of placental dysfunction and adverse perinatal outcome. STUDY DESIGN: Kisspeptin levels were evaluated in the first, second, and third trimesters in patients with type 1 diabetes (16 patients), H (22), and healthy control (25) and in the second and third trimesters in patients with GD (20), gestational hypertension (18), and PE (28). Maternal kisspeptin levels were correlated with pregnancy outcome, parameters of fetoplacental circulation, ultrasound-detected abnormalities of placental morphology, and placental weight at delivery. RESULTS: In pregnancies with type 1 diabetes and H, mean kisspeptin levels were significantly lower compared with the control group (p<0.001 in the first and second trimesters and p<0.05 in the third trimester). Decreased plasma kisspeptin levels in the second and third trimesters were found in patients with GD (p<0.001 in the second and third trimesters) and PE (p<0.001 in the second trimester and p<0.05 in the third trimester). In patients with PE and placental dysfunction, low kisspeptin levels in the third trimester were associated with adverse perinatal outcome. CONCLUSIONS: Our study demonstrates reduced kisspeptin levels in pregnancies with diabetes, H, PE, and placental dysfunction. In patients with PE and placental dysfunction, decreased kisspeptin levels were associated with adverse perinatal outcome. Larger studies are needed to investigate the role of kisspeptin as a potential marker of placental dysfunction and adverse perinatal outcome.

Krukenberg tumor in pregnancy. The lethal outcome.

Krukenberg tumor refers to gastrointestinal cancer metastatic to the ovaries and its prognosis is uniformly poor. This case report concerns a 38-year-old pregnant woman suffering from abdominal pain and iterative vomiting episodes. She presented with a large abdominopelvic tumor. Because of suspected ovarian torsion, we performed urgent surgery. At laparotomy, bilateral ovarian tumors, ascites and gastric cancer located at the cardia and the lesser curvature invading the serosa were identified. We performed right ovariectomy, resection of the left ovary, and gastric biopsy. Histological examination of the specimen yielded diagnosis of Krukenberg tumor. Ten days later the patient underwent an elective Cesarean section in the 25th gestational week because of fetal asphyxia and very poor maternal life prognosis. We performed Cesarean delivery and extracted a vital female newborn of 31 cm, 600 g, Ap score 3, with virilization. Few days later the baby died at the intensive care unit. Two weeks later the mother died because of pulmonary failure.

The attitudes of medical students towards rare diseases: A cross-sectional study.

Background/Aim: Rare diseases are chronic, degenerative and may lead to permanent disability. We aimed to assess knowledge and attitudes of the 3rd and 6th year medical students towards the treatment of rare diseases in Serbia. Methods. In this cross-sectional study, two samples of students were questioned for a survey: 350/446 (78.48%) students of the 3rd year, and 242/517 (46.81%) students of the 6th year. Methods: In this cross-sectional study, two samples of students were questioned for a survey: 350/446 (78.48%) students of the 3rd year, and 242/517 (46.81%) students of the 6th year. Results: Sixth year students estimated that they were more informed on the issue analyzed than the 3rd year students (median value of 4 and 3, interquartile range of 3-5, and 1-4, respectively; p < 0.05). However, a significant percentage of participants estimated incorrectly the prevalence of rare diseases according to the European Union standards (3rd year - 42.68%, 6th year - 49.55%). Core curriculum subjects were the main source of information on rare diseases (3rd year - 63.14%; 6th year - 92.14%). Our participants agreed that the most important problems are the following: high drug prices, difficult access to drugs and lack of public information. Students found, without any differences, that community access to effective drugs for rare disease should be improved (median value - 10, interquartile range 8-10 in both groups, p < 0.05). In order to improve pharmacotherapy of rare diseases in Serbia, the participants suggested establishment of a National Plan for Rare Diseases, approval of more appropriate drugs, simplified access to appropriate medicines, and more rapid diagnostics. Conclusion: It is necessary to improve the knowledge and attitudes of medical students towards pharmacotherapy of rare diseases. [Projekat Ministarstva nauke Republike Srbije, br. 175023]

History of caesarean hysterectomy.

Caesarean hysterectomy evolved as a life-saving procedure following caesarean delivery. The concept underlying caesarean hysterectomy dates back to the mid 1700s and with a description of the procedure performed on laboratory animals. Eduardo Porro of Milan performed the first planned caesarean hysterectomy in which both the infant and the mother survived. He documented his operation in a paper published in 1876. Porro advocated hysterectomy combined with caesarean section to control post partum haemorrhage and to prevent infection. The maternal death rate following the operation remained high, but was substantly below the rate prior to the introduction of the procedure. The Porro procedure contributed to more favourable outcome for both the mother and the infant, having sterility and premature menopause as its side effects. Fortunately, the need for the procedure was soon minimised following the proposal to close the uterine incision with sutures. Although elective caesarean hysterectomy is still a controversial issue, there is no doubt that emergency post partum hysterectomy in case of massive obstetric haemorrhage is potentially life-saving. Over the past decades, the availability of potent uterotonics and broad-spectrum antibiotics, the development of embolisation techniques, and new methods of vessel ligation, have markedly reduced the need for caesarean hysterectomy, which, however, remains an important procedure in modern obstetric practice.

[Maternal autoimmune thyroid disease and pregnancy complication].

BACKGROUND/AIM: Thyroid disorders exert a great impact on pregnancy course and outcome. The aim of the study was to investigate impact of autoimmune thyroid disorders on pregnancy course and outcome, frequency of pregnancy complications and pregnancy loss. METHODS: We followed 63 pregnancies prospectively during the period 1985-2007, 28 with hyperthyroid and 15 with hypothyroid autoimmune disorders, and 20 healthy pregnancies. Follow up included clinical, sonographic and laboratory investigations, including OGTT and postprandial glicemia. RESULTS: There was no difference between previous preterm and term labor in the observed groups (chi2 = 2.309; p > 0.05). Analysis of previous early pregnancy loss showed no significance (chi2 = 4.918; p > 0.05), including varieties of spontaneous and missed abortion (Fisher, p < 0.05). The hypothyroid patients developed gestational diabetes more frequently than the controls (chi2 = 7.638; p = 0.022), which is not the case with hyperthyroid patients (chi2 = 1.078; p > 0.05), or between the groups with thyroid disorders (chi2 = 3.619; p > 0.05). There was no difference among the groups in developing pregnancy-induced hypertension (chi2 = 1.953; p > 0.05). CONCLUSIONS: Controlling thyroid diseases reduces pregnancy complications. Development of gestational diabetes in hypothyroid patients requires controlling glycoregulation in all pregnant women with hypothyroidism.

[Medical treatment of ectopic pregnancy and clinical score].

INTRODUCTION: Ectopic pregnancy is an important cause of morbidity and mortality worldwide. Furthermore, with earlier diagnosis, medical therapy with methotrexate can be offered and surgery avoided in some women, though the best regimen remains unclear. Although there have been advances in the management of ectopic pregnancy, there are still questions to be answered. OBJECTIVE: The use of clinical score was evaluated after the clinical treatment for selection of patients for medical treatment of ectopic pregnancy. METHOD: One hundred and twenty five patients were treated by methotrexate. The administration route was local, ultrasonographically controlled or intramuscular. The first dose of methotrexate was 50 mg and maximal total dosage was 200 mg. RESULTS: Methotrexate treatment of ectopic pregnancy was effective in 85% of cases. In the group of patients with clinical score under 10, the medical treatment was successful in 95% of cases. In the group of patients with clinical score over 14, the medical outcome was successful in 33% of cases. The administration route did not influence the treatment outcome. CONCLUSION: Methotrexate treatment of ectopic pregnancy is a very effective manner of treatment. Clinical (numeric) score is very useful for selection of patients with ectopic pregnancy and may have prognostic value for medical treatment outcome.

Tibolone and osteoporosis.

BACKGROUND: We conducted a 5-year prospective, observational, controlled study to assess the effects of tibolone 1.25 mg/day on bone mineral density (BMD) in postmenopausal women with osteopenia or osteoporosis. METHODS: The subjects were 420 women, an average of 66.4 years old, who had been postmenopausal between 8 and 19 years when enrolled in the study. Of the 420 women enrolled, 346 agreed to take tibolone for 5 years. The 74 who refused tibolone took only calcium/vitamin D supplements and served as the control group. BMD was measured in the lumbar spine and total hip region at baseline and annually by dual-energy X-ray absorptiometry (DXA). RESULTS: At the first two follow-up visits, women taking tibolone had a significant increase in BMD at the spine (P < 0.001) and at the hip (P < 0.001) when compared to baseline values and when compared to BMD values for the control group, which decreased from baseline. In the final 3 years of the study, BMD values (spine and hip) continued to decrease in the control group and also tended to decrease in the tibolone group, but at the end of the fifth year, mean BMD in the tibolone group was still higher than BMD before the start of tibolone treatment (P < 0.05). Calculations showed that if women taking tibolone continued to lose BMD at the same rate as during the final 3 years of the study, after 11 years of tibolone treatment the average patient would have the same BMD as she had when treatment started. CONCLUSION: This 5-year observational study provides evidence that tibolone is effective in increasing BMD in postmenopausal women with osteopenia and osteoporosis during the first 2 years of treatment, but because BMD starts to decline in the third year, it is vital that postmenopausal women start treatment with tibolone as early as possible, so that bone mineral density levels are kept high as long as possible.

Simultaneous diagnosis and therapy of invasive cervical carcinoma and invasive vulvar carcinoma. A case report.

Invasive squamous cell carcinoma of the vulva is predominantly a disease of postmenopausal woman with a mean age of approximately 65 years. After treatment for cervical cancer patients have an increased risk of developing second squamous cell malignancy of the lower genital tract. This study reports the case of a patient with double malignancy-invasive cervical cancer and invasive vulvar cancer. She underwent radical hysterectomy, bilateral adnexectomy and pelvic bilateral lymphadenectomy and at the same time radical vulvectomy and bilateral inguinal lymphadenectomy. After surgery she was referred to radiotherapy. The postoperative course was uneventful and at 14 months of follow-up, the patient showed no evidence of recurrence.
