We present a clinical case of acute hepatitis confirmed by liver biopsy. A 24-year-old patient underwent pulse therapy with methylprednisolone due to the onset of multiple sclerosis. The liver enzyme values were within the normal range 15 days later. Blood tests revealed the development of cytolysis syndrome during an unrelated medical examination two months later. Obvious causes of hepatitis were excluded, and liver biopsy was performed to verify the diagnosis. The biopsy showed a picture of acute hepatitis with high histological activity and development of submassive necrosis. The situation was interpreted as drug-induced liver injury after pulse therapy with methylprednisolone. Oral prednisone therapy was prescribed, and the inflammation and liver injury were reverted. The presented clinical case highlights the importance of follow-up of patients receiving high doses of methylprednisolone.

BACKGROUND: The use of telemedical technologies (TMT) is widespread in providing care to patients of various profiles. However, TMTs are hardly ever used in gastroenterology, despite the extensive digitalization of healthcare. Potential sites for the use of TMTs among gastroenterological patients were assessed. AIM: The study aimed to assess the effectiveness and benefits of TMTs in patients with digestive diseases. Patients with colorectal cancer (CRC): Screening and postoperative management. The TMT intervention increased the number of patients screened for CRC compared to standard face-to-face counseling. In addition, the quality of preparation for colonoscopy was higher in patients who interacted with the physician via TMTs compared to the control group. Most studies reported positive effects of TMTs on quality of life and physical activity in patients with CRC. However, the study by K. Beaver et al. showed that the incidence of CRC recurrence did not differ in the TMT and face-to-face groups. Patients with nonalcoholic fatty liver disease (NAFLD): Correction of lifestyle. When assessing the use of TMTs among NAFLD patients, a significant decrease in alanine aminotransferase and aspartate aminotransferase activity was found compared to that in face-to-face management. The results of the body mass index reduction are contradictory. The most pronounced tendency towards weight loss was observed with the telemedical follow-up of patients over a 6-month period. Patients with irritable bowel syndrome (IBS): Treatment and monitoring of symptoms. Two directions are distinguished in the treatment of IBS by ТМТs. The first is cognitive behavioral therapy (CBT). H. Everitt et al. showed clinically significant improvement in 72.8% of cases after 12 months of web-based CBT. The advantages of using telemedicine in the delivery of CBT include the geographical independence of the physician and the patient, personalization of treatment, and the possibility of ongoing support for the patient and his or her family. The second direction is the use of special diets, such as low-fermentable nutrient diets (FODMAP). Patients following the FODMAP diet supervised by the mobile app reduced symptom severity (odds ratio 55; 95% confidence interval 1198, p=0.01). Special mobile apps (IBS Constant Care) were used to monitor the condition of patients with IBS, which analyze input data and assess severity, providing information to both the patient and the physician. Patients with inflammatory bowel disease (IBD): Patient training and telemonitoring. The study by L. Pang et al. proved that the patients quality of life in the telemedicine intervention group was significantly higher (p=0.03). Another advantage of using TMTs is the provision of access to educational materials about IBD and the possibility of remote contact with the treating physician. The patients ability to obtain necessary information reduces the need for unplanned visits to medical facilities, thus reducing the cost of organizing medical care for patients with IBD. The degree of IBD activity and risk of recurrence and adherence to therapy did not differ significantly between the telemedicine intervention group and the standard face-to-face follow-up group. METHODS: A literature search relevant to the review was conducted in the PubMed database. The studies taken for assessment were those on the use of TMTs among patients with IBD, IBS, NAFLD, and CRC. TMTs were used to access educational information and dietary recommendations, provide information on lifestyle adjustments and physical activity, remind patients to take medicines, consult with physicians, and assess disease activity by completing online questionnaires. The various studies used text messaging, e-mail, mobile apps, websites, and videoconferencing apps as a means of communication. RESULTS: The use of telemedicine in the management of patients with digestive diseases showed high efficiency. TMTs contribute to: Improved quality of life in patients with digestive diseases. Increasing physical activity of patients with CRC and NAFLD. Improved quality of CRC screening. Maintaining remission of IBD and CRC as effectively as face-to-face monitoring. Moreover, the use of TMTs allows personalized treatment, ensures the ongoing support of the patient and his or her family by the medical staff, and provides patients with access to quality educational materials about the disease. CONCLUSIONS: Thus, the use of TMTs is promising in the treatment of digestive diseases and requires wider introduction into practice.

We describe a clinical case of glucocorticosteroid-induced bilateral knee avascular necrosis duiring a new coronavirus infection disease. The development of this pathology is a fairly common complication of GCS therapy, with femoral heads most commonly affected. Timely detection of avascular necrosis is important in the prevention of arthritis and other complications. A clinical caseload is presented in this work. A 54-year-old woman was hospitalized for a new coronavirus infection. She complained of pain in both knee joints two weeks after the onset of the disease. MRI revealed severe avascular necrosis of knee joints on both sides. The patient was prescribed conservative therapy including nonsteroidal anti-inflammatory drugs and bisphosphonate. On follow-up 3 months later, there was no pain, but there was still slight limitation of motion in the knee joints. MRI of both knee joints showed a significant decrease in the previously detected changes.

Introduction. Chest computed tomography (CT) plays a prominent role in determining the extent of pulmonary parenchymal lesions in COVID-19. At the same time, subjectivity of lung lesion volume assessment using 0-4 CT scale in COVID-19 and gradual introduction of low-dose CT (LDCT) requires an investigation of semi-automated lung segmentation accuracy in LDCT compared to CT.Study Objective. To compare the accuracy of affected lung tissue volume calculation between CT and LDCT in COVID-19 using a semi-automatic segmentation program.Material and Methods. The retrospective study was performed on data from the earlier prospective multicenter study registered at ClinicalTrials.gov, NCT04379531. CT and LDCT data were processed in 3D Slicer software with Lung CT Segmenter and Lung CT Analyzer extensions, and the volume of affected lung tissue and lung volume were determined by thresholding.Results. The sample size was 84 patients with signs of COVID-19-associated pneumonia. Mean age was 50.6 ± 13.3 years, and the median body mass index (BMI) was 28.15 [24.85; 31.31] kg/m2. The effective doses were 10.1 ± 3.26 mSv for the standard CT protocol and 2.64 mSv [1.99; 3.67] for the developed LDCT protocol. The analysis of absolute lung lesion volume in cubic centimeters with Wilcoxon Signed Ranks Test revealed a statistically significant difference between CT and LDCT (p-value < 0.001). No statistically significant differences were found in the relative values of lung tissue lesion volume (lesion volume/lung volume) between CT and LDCT using Wilcoxon Signed Ranks Test (p-value = 0.95).Conclusion. The reliability of developed LDCT protocol in COVID-19 for the semi-automated calculation of affected tissue percentage was comparable to the standard chest CT protocol when using 3D Slicer with Lung CT Segmenter and Lung CT Analyzer extensions.
