Paranasal sinuses anatomy is paired in 4 parts which includes frontal, maxillary, ethmoid, and sphenoid. Their relevant function is to secrete mucous for moisture, humidify inspired air, impart vocal resonance, and act as shock absorber for intracranial contents. Retention of secretions in the nasal cavity and sinuses can cause inflammation of the mucosa of paranasal sinuses and lead to infection. Classification of sinusitis is based on duration of symptoms. Diagnosis can be achieved clinically, however other diagnosis modalities such as cultures or radiology can help to achieve accurate diagnosis. Depending on the etiology management can be supportive or pharmacological. In some cases, long term monitoring and prevention therapy may be required.

Identification of changes in biochemical parameters of liver functional activity during screening studies requires additional examination of the patient in order to determine the genesis of the disease. In recent years, in routine practice, the most frequently used is an isolated definition of the level of transaminases (ALT, AST), which does not allow timely detection of latent cholestasis syndrome. Primary biliary cholangitis (PBC), previously referred to as primary biliary cirrhosis, is a relatively rare chronic autoimmune cholesthetic liver disease, predominantly affecting middle-aged women and prone to progressing liver cirrhosis. The recommendations of AASLD and EASL note the need for long-term monitoring of patients with ongoing UDCA therapy and regular diagnostic studies to identify signs of disease progression. A clinical example of successful treatment of a patient with PBC with the Russian drug Exhol® is described.

Advances in remote sensing (RS) technology in recent years have increased the interest in including RS data into one-class classifiers (OCCs). However, this integration is complex given the interdisciplinary issues involved. In this context, this review highlights the advances and current challenges in integrating RS data into OCCs to map vegetation classes. A systematic review was performed for the period 2013–2020. A total of 136 articles were analyzed based on 11 topics and 30 attributes that address the ecological issues, properties of RS data, and the tools and parameters used to classify natural vegetation. The results highlight several advances in the use of RS data in OCCs: (i) mapping of potential and actual vegetation areas, (ii) long-term monitoring of vegetation classes, (iii) generation of multiple ecological variables, (iv) availability of open-source data, (v) reduction in plotting effort, and (vi) quantification of over-detection. Recommendations related to interdisciplinary issues were also suggested: (i) increasing the visibility and use of available RS variables, (ii) following good classification practices, (iii) bridging the gap between spatial resolution and site extent, and (iv) classifying plant communities.
