Incidence and Prevalence of Vaginal Infections in Women of Reproductive Age in North Macedonia

In the available literature on this subject there are many studies which describe the effects of sexually transmitted infections on pregnancy and fertility of women. Because of the frequency of the infections with the atypical bacteria of the Ureaplasma Spp., Mycoplasma Spp., Chlamydia Trachomatis, as well as HPV infections in women of reproductive age, it is easy to underestimate their importance when establishing the basis of the genital health of women of reproductive age. In this prospective analysis, conducted from 2014 to 2018 in the laboratory for HPV and Molecular diagnostics at the University Clinic of Gynaecology and Obstetrics in Skopje, North Macedonia, we analysed the results of 10,387 patients of all ages, of which 973 patients were of reproductive age. A Panel analysis was also conducted (including the above-mentioned pathogens). An HPV analysis was also conducted on 643 patients in this group. Within the group of 643 patients, there was a positive result for HPV in 26.7% of them, while in 40.9% there was a positive result for one or more pathogens on the Panel analysis of bacterial pathogens. The statistical analysis of the results showed that the most frequent of all bacterial pathogens within the Macedonian population of women of reproductive age is Ureaplasma Spp, with an incidence of 33%, followed by Mycoplasma Spp., with 7.8%, while Chlamydia Trachomatis was present in 6.4% of the cases. We should highlight that a co-infection with HPV was present in 18.5% of all the patients where there was analysis of both diagnostic procedures. The analysis of the results in the patients co-infected with HPV and at least one bacterial pathogen on the Panel Analysis, showed a very high statistical correlation (p<001).

Seroprevalence of Lyme borreliosis in forestry workers from Brandenburg, Germany

In 1992 blood samples were taken from 630 forestry workers in the state of Brandenburg, Germany, and an inquiry about tick bites and possible symptoms of Lyme borreliosis carried out in order to determine the seroprevalence of the disease. To estimate the rate of seroconversion within six months, 406 of the individuals were investigated a second time. IgG and IgM antibodies against Borrelia burgdorferi were detected in serum using an indirect immunofluorescence assay (IFA) and an immunoblot assay (IBA). Fifty-three percent of the forestry workers reported suffering a tick bite, 8% of whom recalled an erythema after the bite. Positive results were found more frequently in the forestry workers than in a control group of 200 healthy blood donors in both the IgG-IFA (8% vs. 4%, p < 0.05) and the IgG-IBA (18% vs. 5%, p < 0.05). The detection of IgG antibodies correlated with a tick bite and erythema history. There was a tendency of lower seropositivity by the IgG-IBA in individuals who treated the ticks before removal with chemicals or other agents compared to those without such treatment (16.8% vs. 23.9%, 0.05 > p < 0.1). Likewise, there was a tendency of lower seropositivity by the IgG-IFA in individuals being treated with antibiotics for other reasons compared to untreated individuals (3.15% vs. 8.9%, p < 0.05), although the two groups did not differ in the IgG-IBA (13.8% vs. 18.5%, p > 0.1). The rate of seroconversion within six months ranged from 5 to 7%. It is concluded that forestry workers in Brandenburg, Germany, are at risk for infection with Borrelia burgdorferi, but clinical signs of infection are rare.

[Linear hyperpigmentation caused by bleomycin]

We report on an uncommon but characteristic cutaneous side-effect of bleomycin. A 52-year-old woman being treated for carcinoma of the cervix developed linear hyperpigmentation in wheals in the lumbosacral region, the lateral thorax and above the elbow. The skin lesions appeared during the fourth cycle of chemotherapy with bleomycin. Histologically, incontinence of melanin, focal parakeratosis and a lymphocytic infiltrate with epidermotropism were prominent. By electron microscopic examination metabolically highly active melanocytes were found, with increased number of melanosomes at all stages of maturation and deposits of extracellular melanin in the underlying dermis. The epidermal keratinocytes were unchanged.
