Increased worldwide prescriptions raise adverse effects and overdose concerns, especially for the elderly. Caution is needed in prescribing and considering alternative treatments to minimize risks. Aim: Narrative literature review of potential atrial fibrillation mechanism of action induced by discontinuation of benzodiazepines. Materials and methods: Database PubMed was searched using the combination of keywords – “Benzodiazepine AND atrial fibrillation OR peripheral benzodiazepine receptors”, “history of benzodiazepines”, “benzodiazepines mechanism of action”, “benzodiazepines indications”, “benzodiazepines adverse effects” and “benzodiazepines withdrawal effects”. Non-full-text and non-English scientific publications were removed. A total of 31 publication was included. Discussion: Benzodiazepines (BZDs) were synthesized in 1955 and initially considered less toxic than barbiturates. They interact with GABA-A receptors, causing hyperpolarization and inhibitory effects in the central nervous system. BZDs are used to treat various clinical disorders, but long-term use can lead to adverse effects and withdrawal symptoms. There is evidence that genetic diversity can influence the response to BZDs through GABA receptors. The interaction between benzodiazepines and peripheral benzodiazepine receptors may influence calcium ion channels, affecting cardiac action potential and contractility, and discontinuation of these medications can potentially contribute to atrial fibrillation. Additionally, benzodiazepines may directly affect calcium channels, causing antiarrhythmic effects and vasodilation. Conclusion: In summary, benzodiazepines, once considered safer sedatives, now raise concerns about misuse, dependence, and withdrawal symptoms. While there is a potential link between discontinuing benzodiazepines and atrial fibrillation through mechanisms involving peripheral benzodiazepine receptors and cardiac calcium channels, causality remains uncertain and multifaceted. Further research is needed to clarify these mechanisms, and healthcare providers should exercise caution in long-term benzodiazepine prescriptions while exploring alternative treatment strategies to mitigate risks.","PeriodicalId":34365,"journal":{"name":"Acta Medica Lituanica","volume":"14 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139274589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prenatal course for most fetuses with SCT is generally uneventful, with only a few cases experiencing obstetric and fetal complications. We present the case of a 19-year-old woman who was in good health and had no relevant family or medical history. She was gravida 2 and para 1. During the first trimester scan, an examination revealed a heterogeneous mass in the presacral area with a predominantly multicystic appearance, measuring 12 mm in diameter. At 21+6 weeks of gestation, the Type 2 fetal SCT showed an increase in volume with the size of 49×37×36 mm and contiune to increase in size. The male fetus was delivered by elective Cesarean section at 38 weeks of gestation. The resection of the tumor and coccyx was performed when the newborn was 7 days old. The tumor measured 190×160×100 mm and weighed 1100 g. Pathological examination confirmed the diagnosis of a mature teratoma (Grade 0), and the resection margins were negative.

Architectural properties of the muscles are the prime predictors of functional attributes and force-generating capacity of the muscles. This data is vital for musculoskeletal modelling and selecting the appropriate muscle–tendon units for tendon transfers.Cadaveric data for architectural properties is the gold standard and primary input for musculoskeletal modelling. There is a paucity of these datasets, especially in the leg muscles.Methods. Sixty muscles of the anterior and lateral compartments from twelve formalin-fixed lower limbs were studied for gross architecture, including the peculiar fibre arrangements and architectural properties of muscles. Muscle weight, muscle length, fibre length, pennation angle and sarcomere length were measured. Normalised fibre length, fibre length to muscle length ratio (FL/ML ratio), and the physiological cross-sectional area (PCSA) were calculated from the obtained data.Results. Muscles displayed a combination of architectural strategies and were partly fusiform and partly pennate. The tibialis anterior and peroneus longus were the heaviest muscles in their respective compartments and showed more extensive origin from the nearby deep facial sheets.Long fibre length and less pennation angle were seen in muscles of the extensor compartment. Potential muscle power was highest in the tibialis anterior and peroneus longus and least in the extensor hallucis longus.Conclusions. Arching of the foot and eversion are peculiar to humans and recent in evolution. Due to the functional demand of maintaining the medial longitudinal arch and eversion, the tibialis anterior and peroneus longus have more muscle weight and larger physiological cross-sectional area and are potentially more powerful.Extensor compartment muscles were architecturally more suited for excursions because of the long fibre length and less pennation angle.This study contributes baseline normative data for musculoskeletal modelling platforms and simulation tools – an emerging area in biomechanics and tendon transfers.","PeriodicalId":34365,"journal":{"name":"Acta Medica Lituanica","volume":"88 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139277664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We measured the demographic and clinical characteristics of patients with post-COVID-19 dysautonomia in terms of the quality of life with the EQ-5D-3L, and anxiety and depressive symptoms by employing Patient Health Questionnaire-4.Results: The study population included 122 patients with post-COVID-19 syndrome. One out of four patients (27.8%) manifested post-COVID-19 dysautonomia, while the mean duration of COVID-19 symptoms was 11.6 months. Anxiety and depressive symptoms were worse after the post-COVID-19 syndrome (p<0.001 in both cases). A statistically significant reduction in quality of life was observed among patients after the post-COVID-19 syndrome (p<0.001 for both EQ-5D-3L index value and EQ-5D-3L VAS). Post-COVID-19 dysautonomia increased depression symptoms after developing the post-COVID-19 syndrome (p=0.02). We found a negative relationship between the duration of COVID-19 symptoms and the quality of life (p<0.001). Moreover, our results showed that depressive symptoms were more common among females after the post-COVID-19 syndrome (p=0.01). Also, the quality of life was lower among females than males (p=0.004 for EQ-5D-3L index value, and p=0.007 for EQ-5D-3L VAS).Conclusions: Our results suggest that post-COVID-19 syndrome causes a tremendous impact on the patients’ quality of life and mental health. In addition, we found that the groups most psychologically affected were patients with post-COVID-19 dysautonomia, females, and patients with a longer duration of symptoms. Policy makers should assign priority rights to vulnerable groups in future psychiatric planning. Policy measures should focus on the mental health of post-COVID-19 patients who seem to be particularly vulnerable.","PeriodicalId":34365,"journal":{"name":"Acta Medica Lituanica","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135824403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nephrotic children may develop thyroid hormone dysfunction due to urinary excretion of thyroid hormones. In contrast to the subclinical hypothyroidism that affects around 30% of children with nephrotic syndrome (NS), the patient in this case had overt hypothyroidism and severe growth retardation.Clinical case. A 5 years and 8 months old girl with steroid-dependent NS was referred from another center due to persistent edema and decreased diuresis, being treated with mycophenolate mofetil (MMF) 250 mg once a day and L-thyroxine 50 mcg daily since 4 months of NS onset because of hypothyroidism. Her albumin was 12.64 g/l, cholesterol 25.64 mmol/l and proteinuria 5 g/l. Severe growth retardation was observed: patient’s height was 93.5 cm (–13 cm <3 percentile), weighted 17.2 kg (15–25 percentile). Her disease vintage was over 3 years. Girl’s growth velocity has slowed down from 3.5 months. The patient received a high cumulative dose of prednisolone (approx. 7800 mg in 1 year and 8 months). Thyroid-stimulating hormone was higher (18.04 mU/L) with reduced FT4 11.43 pmol/l and IGF-1 < 15 µg/L. Kidney biopsy revealed minimal change disease, and genetic testing was negative. Intensive NS treatment with methylprednisolone pulse therapy, enlarged doses of MMF and albumin infusion were started and L-thyroxine dose was increased to 75 mcg. TPOAb was in normal range (12.65 IU/ml). After 3 weeks she was discharged with no edema and after stopping methylprednisolone treatment thyroid function normalized and L-thyroxin was discontinued. Two weeks later standard growth hormone stimulation test with clonidine showed partially insufficient growth hormone secretion. During NS remission with normalization of thyroid function (TSH 6.680 mU/l, FT4 13.85 pmol/l) and normalization of IGF-1 level (132 mcg/l) partial catch-up growth was observed (height velocity increased from 3.5 cm/year to 7.3 cm/year, based on 4-month calculation period).Conclusions.

Lithuania has the third-highest tuberculosis incidence rate per 100,000 and the second-highest mortality rate per 100,000 in EU/EEA countries. During 2015–2021 years, there were 799 deaths of pulmonary tuberculosis in Lithuania. However, the presence of pulmonary tuberculosis is often unknown before death and is only revealed during autopsy. The aim of the study is to review current literature on this topic and present statistical analysis on evaluated socioeconomical, epidemiological indicators, as well as autopsy findings that may suggest pulmonary tuberculosis infection.Materials and methods: This research was designed as a retrospective study focusing on full forensic pathology autopsies between 2015 and 2021. Of these, 100 cases were randomly selected where the cause of death was tuberculosis diagnosed during post-mortem examination and compared to a control group consisting of 415 cases of sudden death.Results: The study revealed that out of 100 pulmonary tuberculosis cases, 90% were male with the mean age of 53.48 ± 11.12 years old. In the case of sudden death where tuberculosis was found, a significant portion of the sample (91%) was not followed up at any medical institution. Regarding socioeconomic factors, a moderate negative correlation between Lithuania’s gross domestic product and tuberculosis distribution was observed, as well as a weak negative correlation between alcohol consumption (l per capita) in the general population and tuberculosis distribution. The lung weight of the pulmonary tuberculosis group was statistically significantly higher than that of the control group.Conclusions: Tuberculosis remains a major problem in Lithuania and the combination of socioeconomic indicators determines the prevalence of tuberculosis in the country. In cases of sudden death, autopsy helps to identify tuberculosis cases that have not been clinically detected and ensures tuberculosis monitoring. Therefore, the person who performs autopsy remains at high risk of contracting tuberculosis. Furthermore, extreme caution is advised if higher lung weight or hardenings are seen during autopsy because of the possibility of tuberculosis.","PeriodicalId":34365,"journal":{"name":"Acta Medica Lituanica","volume":"64 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135824096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
