This overview is devoted to the analysis of the results of modern clinical studies and the approaches towards the management of hyperprolactinemia caused by prolactinoma...

BACKGROUND: Tuberculosis is one of the most common infectious diseases in the world. 10.6 million people fell ill in 2021 and 1.6 million died from the disease. 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...

INTRODUCTION: Benzodiazepines are commonly prescribed but often misused, leading to dependence and withdrawal symptoms. 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 combinations 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"...

Crush syndrome (CS) is a metabolic disorder whose victims are individuals suffered from natural disasters such as earthquake or man-made conflicts. CS complications include acute kidney injury and cardiac arrhythmia that collectively end with death if untreated immediately. These complications are accounted for the liberation of damaged muscle tissues contents, primarily myoglobin and potassium. The present mini review discusses the biochemical basis of the development of CS. In addition, diagnosis and management and the application of novel experimental therapeutics of CS are also highlighted...

Patients with bile duct cysts require careful radiological assessment of the hepatobiliary system prior to surgical intervention. This clinical case is uncommon with an atypical clinical presentation and radiological findings. According to the most widely used classification of choledochal cysts, this case presents a combination of Type I and Type IV of choledochal cyst (CC) combining the form of extra, intrahepatic bile ducts and cystic duct dilations.

BACKGROUND: Increased enzyme activity in human blood serum is usually associated with the existence of disease. On the other hand, enzyme activity can also be elevated in the presence of benign conditions, such as macro-enzymes. Macro-enzymes could lead to highly unnecessary and invasive procedures which may cause complications to the patient and an extra cost for the hospital. Therefore, it is important to diagnose this condition in order to avoid unnecessary clinical tests. CASE PRESENTATION: We present a case of a 71-year-old asymptomatic female with persistent elevation of AST who was referred to our hospital for additional testing for underlying liver disease...

BACKGROUND: 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...

BACKGROUND: Schwannomas of the gastrointestinal tract are a rare type of spindle cell tumor of peripheral nerve. Commonly, schwannomas are discovered incidentally, as they are usually asymptomatic. CASE: 46-year-old female patient, suffering from secondary amenorrhea and nonspecific intermittent pelvic pain associated with constipation. During gynecological visit an ultrasonographic systematic transvaginal examination was performed. At the sigmoid-rectal level an intraluminal solid mass was described and an urgent colonoscopy was prescribed...

BACKGROUND: 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...

Sacrococcygeal teratoma (SCT) occurs in approximately 1 per 20,000-40,000 births and is the most frequently encountered fetal teratoma, with 75% of cases observed in female fetuses. SCT can be detected on ultrasound as early as the first trimester, presenting as a large mass originating from the sacrococcygeal area, with or without an intrapelvic component. 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...

DISCUSSION: The clinical presentation of IPMNs is usually nonspecific; common symptoms are abdominal pain, weight loss, and jaundice...

Iatrogenic femoral artery pseudoaneurysms (IFAPs) are not uncommon due to the increase in various minimally-invasive endovascular procedures. Percutaneous thrombin injection is an established technique for large pseudoaneurysms. When ultrasound-guided compression of an aneurysmal neck is not feasible, percutaneous thrombin injection can be combined with endovascular balloon occlusion to prevent leakage of thrombin into the parent artery. We describe a large IFAP following the removal of the femoral dialysis catheter after an inadvertent arterial puncture, which was managed with percutaneous ultrasound-guided (USG) thrombin injection with simultaneous balloon occlusion at the level of the aneurysmal neck without any complications...

Hypereosinophilic syndrome (HES) is a heterogeneous group of disorders characterized by peripheral blood eosinophilia of 1.5 × 109 /L (1,500/μL) or greater, with evidence of end-organ damage attributable to eosinophilia (e.g., heart, liver or lung) with no other cause for the end-organ damage [1]. Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare disorder that may affect multiple organ systems (lungs, heart, kidneys, or the nervous system). The disorder is characterized by hypereosinophilia in the blood and tissues, inflammation of blood vessels (vasculitis), and the development of inflammatory nodular lesions called granulomatosis [2]...
