In diagnosing COVID-19, false negative findings from the biological sample taken from a mucosal swab of the upper respiratory tract and tested with the real-time reverse-transcription polymerase chain reaction (RT-PCR) technique have been reported. This patient has had a proven contact with an infected person, clear symptoms of viral respiratory disease, yet negative test results on the fifth day of self-isolation. On repeated test after 48 hours, on the 7th day of isolation, due to persistence of some symptoms, he tested positive for SARS-CoV-2. The existence of symptoms and characteristic sings after laboratory and radiological analysis of the patient prompted the repetition of the tests, which at the end led to the confirmed diagnosis and the possibility for adequate treatment of the patient as well.

Background/Aim: Pulmonary embolism (PE) is a diagnostic challenge, particularly in prehospital care. The aim of this study was to determine to what extent the evaluation of D-dimer value helps physicians with differentiation of PE and whether D-dimer values are in correlation with the values of revised Geneva score. Methods: Data have been collected for the patients whose D-dimer has been evaluated at the Emergency Care Department of the City of Banja Luka in 2018. Gender, age, symptoms, working diagnosis and D-dimer value have all been recorded and also the fact whether the patient was referred to hospital treatment or not. For each patient the revised Geneva score was determined. Results: Sixty-eight tests were done in 2018. Out of 68 tests, 41 were negative (60.3 %). D-dimer results helped in making decisions about referring patients to the hospital or not (ch2 = 36.32, p < 0.001). Patients with elevated D-dimer levels, especially where the values were four times higher than the reference ones typically were referred to hospital treatment, whereas 67.5% patients with negative D-dimer results were sent home after giving a treatment and advice. In the elderly patients D-dimer was statistically more positive (F = 10.82, p < 0.001). Values of D-dimer were not significantly different regarding gender (ch2 = 2.19, p = 0.33). According to the results of the revised Geneva score, 5.1 % of patients had high risk of PTE, while moderate and low risk had 47.5 % each. Although it has been found that the values of D-dimer were slightly more elevated at higher values of the revised Geneva score and that the difference was not statistically significant (ch2 = 7.71, p = 0.10). Conclusion: Values of D-dimer considerably helped in differentiation of PE in the Emergency Care Department. D-dimer has a high negative predictive value and should be used to exclude PE diagnosis for patients with low clinical probability of PE.

Background: Benzodiazepines (BZDs) are very often inappropriately prescribed drugs. The aim of this study is to analyse physicians' prescribing patterns for BZD in Republic of Srpska, and to assess to what extent primary diagnosis determine the dose and the length of use of BZDs. Methods: A retrospective analysis of the physicians' prescription habits based on the database of Family Medicine Information Systems of Republic of Srpska, as well as on data from patient’s medical record were performed. Patients’ socio-demographic and clinical characteristics, including the data on the type and dose of BZDs prescribed, were recorded and evaluated. Results: BZDs were mostly prescribed for anxiety disorders (30.05%), for depressive disorders (17.54%), and for anxiety-depressive disorders (10.86%). A significant amount of BZDs was prescribed for non-psychiatric diagnoses (23.81%). Patients suffering from psychotic disorders were taking the highest dose of BZD and for the longest periods of time (p<0.001). Longer use of BZDs was in women (r=0.04, p<0.001), elderly (r=0.178, p<0.001), single people (r=0.12, p<0.001), those who live in urban areas (r=0.45, p<0.001) and those who were prescribed higher doses (r=0.213, p<0.001). Conclusion: A significant percentage of patients were using the BZDs for longer period of time than recommended. Strongest positive correlation was found between the dose and the length of use, which implies the addictive potential of BZDs. Since it has been noticed that prolonged use, or abuse is present regardless of the diagnosis, precaution is advised when prescribing BZDs even for acute diseases.

Depression is becoming a widespread illness. One of the most dangerous types of depression is postpartum depression. In the presented case of postpartum depression, aggravating factor was patient’s personality structure. With the frequent giving up on previous therapy, frequent mood swings, and the present feeling of helplessness, the very treatment of depressive episode within the postpartum depression was difficult. In this case report, the introduction of aripiprazole as a drug with a proven effect on mood swings and tendency to mood stabilisation resulted with complete and long-lasting remission.

The most common hazards in the forestry that may induce disorders of the musculoskeletal system are vibrations, unfavorable microclimatic conditions, noise, over-time working hours, work load and long-term repeated movements. The objective of this study was to analyze the prevalence of musculoskeletal diseases and its difference among workers engaged in various jobs in the forestry. Two groups of workers were selected: woodcutters operating with chain-saw (N=33) and other loggers (N=32). Selected workers were of the similar age and had similar total length of employment as well as the length of service in the forestry. Both groups of workers employed in the forestry had the high prevalence of musculoskeletal diseases (woodcutters 69.7% and other loggers 62.5%, respectively). Degenerative diseases of spinal column were very frequent, in dependently of the type of activity in the forestry. Non-significantly higher risk of carpal tunnel syndrome was found in woodcutters with chain-saw compared to workers having other jobs in the forestry (OR=3.09; 95%CI=0.64-19.72). The lateral epicondylitis was found only in woodcutters operating with chain-saw with the prevalence of 18.2%.
