Pregnancy outcomes of COVID-19 positive pregnant women at the Cantonal Hospital Zenica, Bosnia and Herzegovina.

Aim To investigate clinical presentation of COVID-19 infection in pregnancy, its course during pregnancy, effects on pregnancy outcomes for both mothers and newborns as well as the potential for vertical transmission. Methods This retrospective observational study included all identifi ed COVID-19-positive pregnant women admitted to the Cantonal Hospital in Zenica at any stage of pregnancy or labour from 30 April 2020 to April 30 2021. Maternity and newborns were followed until discharge from the hospital. Results Twenty-four pregnant women were positive for COVID-19. There were 79.2% asymptomatic cases, 12.5% had mild symptoms, while 8.3% had more severe forms of the disease. The main follow-up morbidities were high BMI 33.3%, anaemia 16.7%, thrombocytopenia 12.5%, hypertensive disorders 4.2% and diabetes 4.2%. The rate of premature births was 33.3%, while 8.3% pregnant women had premature rupture of the amniotic sac. Caesarean section was done for 75% women while 25% delivered vaginally. Previous caesarean section (54.2%) was the most common indication for operative completion of labour. Twentythree (92%) live babies were born, of which 8 (33.3%) were admitted to the neonatal intensive care unit. Two (8%) intrauterine foetal deaths were recorded that occurred before admission to our hospital. Two infants (8.7%) had a positive PCR test for COVID-19. Conclusion COVID-19 viral disease in pregnancy is usually presented as an asymptomatic or mild disease. It is associated with high rates of preterm birth, admission of newborns to the intensive care unit and intrauterine foetal death. Vertical transmission is possible but the newborns were asymptomatic.

A one-year review of macrosomic births at the Cantonal Hospital Zenica, Bosnia and Herzegovina.

Aim To identify a rate of macrosomic births in a one-year review, associated maternal characteristics and pregnancy outcome. Methods This one-year retrospective review included all macrosomic deliveries at the Department of Obstetrics and Gynaecology at the Cantonal Hospital Zenica between 1 January 2018 and 31 December 2018. The data were collected from maternal and newborn medical records. A total of 361 singleton normal birth weight term newborns (birth weight <4000 g, but not small for gestational age) who were delivered in the same period, represented the control group. Results Among the total of 2758 women who gave birth, 360 (13.05%) macrosomic infants (birth weight more than 4000 g) were delivered. Mean birth weight was 4258.90 g (maximum 5460g); nine (0.33%) were >5000g. Male macrosomic infants were more frequently represented, 245 (68,1%) comparing to the control group (p<0.01); in the control group female infants were more frequently represented (p<0.01). The overall Cesarean section rate, including elective Cesarean delivery was 23.2%, and 76.1% underwent an attempt of labour delivered vaginally. Conclusion Macrosomia represents a risk for adverse outcome for the mother and neonate, with a higher risk for the operative mode of delivery.

Nitric oxide biosynthesis during normal pregnancy and pregnancy complicated by preeclampsia.

Aim To investigate biosynthesis in nitric oxide (NO) during normal pregnancy and in pregnancies complicated by preeclampsia. Methods This prospective cross-sectional study included 80 patients hospitalized at the Department of Women's Health, Neonatology and Perinatology Cantonal Hospital in Zenica. Serum NO concentration in 20 non-pregnant women, 40 healthy pregnant women and 20 pregnant women with preeclampsia aged 17-40 years were measured. The group of healthy pregnant women were divided into 4 subgroups by gestational age. For each woman with preeclampsia, a healthy pregnant control was matched for age, parity and gestational age. Serum NO concentrations were determined after reduction of nitrates to nitrites using the Griess reaction. Results NO concentrations during second trimester of pregnancy (37.2±1.7µM; p<0.05) and third trimester of pregnancy (40.9±2.8µM; p<0.05) were significantly higher in healthy pregnant women than in non-pregnant women (29.3±1.7µM). Serum NO concentrations were lower in preeclamptic women (30.7±1.8µM) compared to matched healthy pregnant women of the third and the late third trimester (35.1±2.2µM), without significant differences. Mean NO concentrations in pre-eclamptic women was positively correlated with systolic blood pressure (r=0.58; p<0.01), diastolic blood pressure (r=0.45; p<0.05), creatinine clearance (r=0.48; p<0.05), uric acid (r=0.49; p<0.05), and negatively correlated with platelet count (r=-0.57; p<0.05). Conclusion NO production was increased with gestational age during normal pregnancy and slightly decreased in preeclampsia suggesting that NO may modulate the cardiovascular changes during normal pregnancy and pregnancy complicated by preeclampsia.

Occupational risk factors for prostate cancer in an area of former coal, iron, and steel industries in Germany. Part 2: results from a study performed in the 1990s.

Currently, there is no established occupational risk factor for prostate cancer. However, in the 1980s, a hospital-based case-control study in the greater Dortmund area showed an elevated risk for hard coal miners and, based on few cases, for painters and varnishers. Therefore, approximately 10 yr later, a similar study regarding prostate cancer was performed in this area. In total, 292 patients with prostate cancer who underwent radical prostatectomy and 313 controls who underwent transurethral resection of a benign prostatic hyperplasia were investigated by questionnaire. All of them were operated on between 1995 and 1999. This study showed a decreased risk for prostate cancer in hard coal miners (odds ratio [OR] = 0.67, 95% confidence interval [CI] = 0.44-1.03). Occupational exposures related to an elevated risk for prostate cancer were exposures to combustion products (20% cases vs. 11% controls), colorants and dyes (19 vs. 13%), and cutting fluids (8 vs. 6%). The different prostate cancer risks for underground coal miners in two studies with a time interval of approximately 10 yr are striking. Factors to be discussed are the introduction of prostate-specific antigen (PSA) screening for prostate cancer and investigation of cases that underwent radical prostatectomy, where the disease in general is locally confined. Working conditions in the local underground coal mines improved over time but did not change markedly in the period of interest. In essence, the present study does not corroborate an elevated prostate cancer risk in former underground hard coal miners from the greater Dortmund area.

Effect of antihypertensive therapy with alpha-methyldopa on umbilical artery Doppler in pregnancies with hypertensive disorders.

Aim To clarify whether applying alpha-methyldopa treatment influences flow resistance in umbilical cord artery in pregnant women suffering from hypertensive disorder. Methods In this prospective cross-sectional study a follow-up was done for 50 pregnant women with singleton pregnancies between 36 and 40 gestation weeks, who had been hospitalized at the Gynecology and Obstetrics Department of the Cantonal Hospital Zenica, Bosnia and Herzegovina from October 2009 to January 2012. Pregnant women were classified in two groups according to the level of using alpha-methyldopa in the treatment. For all expectant mothers, flow in umbilical cord artery was measured, Resistance Index (RI) was determined and values were compared accordingly. Results There was a statistically significant difference in values of umbilical artery resistance index (UA RI) in terms mother's hypertension (p less than 0.05). Therefore, mothers with chronic hypertension had the highest UA RI (0.885±0.4), as well as mothers with preeclampsia superimposed on chronic hypertension (0.785±0.7), while mothers with gestational hypertension had the lowest UA RI (0.6413±0.13) (p less than 0.05). In mothers using the methyldopa UA RI was lower (0.6875±0.14) in comparison to those who did not use it (0.6686±0.13) but with no statistical significance (p greater than 0.05). Conclusion There was no change in flow resistance in umbilical cord artery in pregnant women suffering from hypertensive disorder. Key words: ultrasonography, umbilical artery, pregnancy-induced hypertension.

Bladder cancer documentation of causes: multilingual questionnaire, 'bladder cancer doc'.

There is a considerable discrepancy between the number of identified occupational-related bladder cancer cases and the estimated numbers particularly in emerging nations or less developed countries where suitable approaches are less or even not known. Thus, within a project of the World Health Organisation Collaborating Centres in Occupational Health, a questionnaire of the Dortmund group, applied in different studies, was translated into more than 30 languages (Afrikaans, Arabic, Bengali, Chinese, Czech, Dutch, English, Finnish, French, Georgian, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Kannada, Kazakh, Kirghiz, Korean, Latvian, Malay, Persian (Farsi), Polish, Portuguese, Portuguese/Brazilian, Romanian, Russian, Serbo-Croatian, Slovak, Spanish, Spanish/Mexican, Tamil, Telugu, Thai, Turkish, Urdu, Vietnamese). The bipartite questionnaire asks for relevant medical information in the physician's part and for the occupational history since leaving school in the patient's part. Furthermore, this questionnaire is asking for intensity and frequency of certain occupational and non-occupational risk factors. The literature regarding occupations like painter, hairdresser or miner and exposures like carcinogenic aromatic amines, azo dyes, or combustion products is highlighted. The questionnaire is available on www.ifado.de/BladderCancerDoc.

[Intact twin tubal pregnancy]. / Intaktna blizanacka tubarna trudnoca.

A case of a unilateral eight-week twin ectopic pregnancy diagnosed with transvaginal sonography is presented here. This ectopic pregnancy was found in the right Fallopian tube of a 35-year old woman. After the surgical procedure conducted by the method of transversal laparotomy, we removed the right Fallopian tube with two gestational sacs So far only a hundred of such cases of ectopic twin pregnancy have been described worldwide.

Elevated bladder cancer risk due to colorants--a statewide case-control study in North Rhine-Westphalia, Germany.

Occupational exposure to aromatic amines is a known bladder cancer risk factor, whereas the impact of exposure to azo dyes, which may release aromatic amines in humans, is at present controversial. Therefore, the impact of occupational exposures to colorants was investigated in 156 bladder cancer cases and 336 controls in the state of North Rhine-Westphalia. All bladder cancer cases and controls (diagnosed with prostate cancer) requested after-care treatment. The subjects were investigated using a questionnaire for all occupations ever performed for more than 6 mo and for exposures to several possible occupational and nonoccupational bladder carcinogens. The relative bladder cancer risk was adjusted for age and smoking. The adjusted odds ratio (OR) for bladder cancer was elevated in 7 painters (OR 1.98, 95% CI 0.64-6.11), 4 hairdressers (OR 4.9, 95% CI 0.85-28.39), and 16 cases who reported a wood processing occupation (OR 1.19, 95% CI 0.58-2.41). Ten of these 16 cases reported chronic exposure to colorants (OR 1.84, 95% CI 0.68-4.95). The results of this epidemiological study confirm the hypothesis that individuals exposed to colorants show an elevated bladder cancer risk.

Primary testicular carcinoid.

BACKGROUND: Testicular tumors in general can be classified as seminoma, embryonal carcinoma, teratocarcinoma, choriocarcinoma, and mixed tumors. Nevertheless, other histological types may also be observed. In rare cases, primary or secondary neuroendocrine tumors derived from chromaffine cells can be observed in the testicle. CASE REPORT: A 51-year-old patient was hospitalized on account of a two-month-old painless tumescence of the right testicle. Radical orchiectomy revealed a solid, inhomogeneous intratesticular tumor 3 cm in diameter. Pathohistological findings and immunohistochemical staining with different neuroendocrine markers revealed a testicular carcinoid classified as pT1. The excretion of 5-hydroxyindole-acetic acid (5-HIAA) was within the normal range. No further carcinoid tumor site was found. CONCLUSIONS: In case of a testicular carcinoid, exclusion of a primary carcinoid tumor site in other organs is mandatory.
