For the diagnosis and differentiation of chronic cholesistoxolangiitis from the diseases of the biliary system, 20 patients used modern instrumental and laboratory methods. In these methods, excision cholesistorentgenography, retrograde cholangiography, high frequency ultrasound examination, and cholesterol in the blood, manometric tonometry. In the objective examination, patients were disturbed by the pain on the right side of the neck, on the right side of the breast and in the right rib. Dyspeptic symptoms such as lower appetite, nausea, vomiting, and meteorism have been discovered. Dietotherapy, spasmolitics, antibiotics, gallbladder and physiotherapy have also been used in the treatment. Thus, based on the results of our examination, it is recommended that they be used in early diagnosis of chronic cholesistoxolangitis. Key words: cholangiocholecystitis, gallbladder, symptoms, clinical, diagnosis

Aim of the study: The aim of this study is to evaluate the utility of high-frequency ultrasound in the assessment of the nature and differentiation of lumps occurring in the labial mucosa after lip filling procedures. Material and methods: The study sample included 5 women aged from 28 to 43 years (mean age: 37.4 years) who previously underwent a lip augmentation or rejuvenation procedure. Photographic documentation was taken and high-frequency ultrasound assessment was performed in all the patients. The presence of deposits, foreign body granulomas, fibrosis and labial glands was mainly investigated taking into account the shape of the abnormalities, their margins, surface area, location and echogenicity. In order to confirm the diagnosis, histopathological examination was performed. Results: The examinations performed made it possible to differentiate between granulomas and persistent deposit nodules and to demonstrate the presence of massive fibrosis and of labial glands pushed out by these abnormalities with the glands presenting as hypoechoic oval areas. Histopathological examination confirmed the morphology of labial glands reported by the patients as uncomfortable lumps felt from the side of the mucosa, which clinically simulate persistent deposit nodules or granulomas. Conclusions: High-frequency ultrasound is a method that is essential for the correct differentiation between complications of tissue filler procedures. This, in turn, makes it possible to apply the right treatment. In this study, it was demonstrated for the first time that the lumps reported by patients who have had a lip filling procedure may be the result of labial glands being pushed out by deposits, granulomas or massive fibrosis, which are complications of such procedures.

Objective: Proprotein convertases (PCSKs) process matrix metalloproteases and cytokines but their function in vasculature is largely unknown. Previously, we demonstrated upregulation of PCSK6 in atherosclerotic plaques, localization to smooth muscle cells in the fibrous cap and positive correlation to inflammation, extracellular matrix remodeling and cytokines. Here, our aim was to evaluate the effects of PCSK6 on flow-mediated vascular remodeling in mice using high-frequency ultrasound and myography. Materials and Methods: PCSK6 -/- and C57Bl/6J mice were compared in this study divided in baseline control and increased flow groups. Increased flow was created in the right common carotid artery (CCA) by ligation of the left CCA. All animals were subjected to high-frequency ultrasound examination prior to surgery, at 3 and 5 weeks after surgery. Upon euthanization 6 weeks post-surgery the right CCA was harvested for myography evaluation, subsequently fixed at optimal stretch and prepared for histological evaluation. Results: The vascular circumference at optimal stretch in myography was strongly correlated (Pearson r=0.74, p<0.001) and in agreement with the diastolic circumference measured by high-frequency ultrasound in examined animals. A significant increase in diastolic circumference was seen at 3 and 5 weeks after surgery in PCSK6 -/- mice with increased flow compared to PCSK6 -/- control group (1.6±0.15 mm vs 1.4±0.08 mm, p<0.05 and 1.7±0.09 mm vs 1.4±0.12 mm, p<0.01). Myography revealed a significant increase in circumference at optimal stretch (1.7±0.21 mm vs 1.4±0.08 mm, p<0.05) in PCSK6 -/- mice subjected to increased flow compared to PCSK6 -/- control group. A significant flow-mediated increase in medial contractility was identified (0.68±0.14 mN/mm vs 0.45±0.11 mN/mm, p<0.05) in C57Bl/6J mice compared to C57Bl/6J control where as an absence of flow-mediated increase in medial contractility was seen in PCSK6 -/- mice. Conclusion: Absence of PCSK6 increases outward remodeling and reduces medial contractility in response to increased blood flow.

The objectives of this study were to: (1) establish the causes of scrotal swelling in the hospital catchment population; (2) define the role of high frequency ultrasound examination in the management of scrotal swelling. A retrospective study of 582 patients who had high frequency ultrasound examination was carried out. Those requiring more information on perfusion had colour doppler examination. Forty-four per cent of examinations were performed for scrotal swelling. The cause of the scrotal swelling was mainly extratesticular (75% of all scrotal swellings), hydrocele being the commonest. Of the intratesticular causes, infection (50.8%) and tumour (20.6%) were the commonest. In conclusion ultrasound examination distinguishes extratesticular (almost always benign) from intratesticular (potentially malignant) causes of scrotal swelling. Infection, trauma and torsion mimic the ultrasound appearance of tumour as do rare benign entities.
