Summary. The study of various markers indicating an imbalance in both the neurotransmitter and immune systems observed in patients with schizophrenia is currently of great scientific and practical interest. These studies allow us to deepen knowledge about the etiology and pathogenesis of schizophrenic spectrum disorders, to facili-tate the classification and conduct of differential diagnosis in complex diagnostic cases. The article presents the results of laboratory studies of DMT-1, CD4, CD20, CD34 and dopamine in 24 people suffering from paranoid schizophrenia, and 14 healthy individuals. The aim of the study was to determine DMT-1, CD4, CD20, CD34 and dopamine as possible markers for the diagnosis of schizophrenia using the minimally invasive method.Materials and methods: Buccal epithelium was taken in 2 groups of patients suffering from paranoid schizophrenia receiving and not receiving therapy with psychotropic drugs. The third group consisted of healthy volunteers. The samples were studied by the immunocytochemical method followed by visualization using scanning laser confocal microscopy and morphometric analysis.Results and discussion: : It was revealed that the markers studied were found to be associated with the nature of mental disorder, but not with the influence of psychotropic drugs used in it. Conclusion: The results of this study may indicate the possibility of minimally invasive diagnosis of schizophrenia using this method; however, the authors note that the results of the study should be considered preliminary. It is necessary to expand the number of patients and compare them with groups of patients suffering from other mental disorders, which is certainly important for assessing the adequacy of the proposed method and the possibility of its use in differential diagnosis.

The practice of systematic examinations in hospitals and the increasing development of automatic data processing permits the storing of a great deal of information about a large number of patients belonging to different diagnosis groups.To predict or to characterize these diagnosis groups some descriptors are particularly useful, others carry no information. Data screening based on the properties of mutual information and on the log cross products ratios in contingency tables is developed. The most useful descriptors are selected. For each one the characterized groups are specified.This approach has been performed on a set of binary (presence—absence) radiological variables. Four diagnoses groups are concerned: cancer of pancreas, chronic calcifying pancreatitis, non-calcifying pancreatitis and probable pancreatitis. Only twenty of the three hundred and forty initial radiological variables are selected. The presence of each corresponding sign is associated with one or more diagnosis groups.

The incidence of focal lesions in the spleen is 3.2–4.2% per 100,000 population. Spleen cysts are rare (incidence 0.75 per 100,000). These are single or multiple, thin- and smooth-walled cavities filled with a transparent liquid. Distinguish between primary (or true) cysts, lined with epithelium, and secondary (or false), devoid of epithelial lining. Among the primary cysts, there are congenital cysts formed in the embryonic period due to the migration of peritoneal cells into the spleen tissue, dermoid and epidermoid cysts. A special group of primary cysts are parasitic cysts. Cystic tumors of the spleen include lymphangioma and lymphoma.The main difficulties in the diagnosis and differential diagnosis of cysts and cystic tumors of the spleen are associated with the rarity of this pathology and, as a consequence, a small number of works, including a significant number of the cases. However, in those works where a large number of the cases are described, most often this is one morphological form and an analysis of its various characteristics.Purpose. Based on the analysis of our own examination data of a significant number of patients with cysts and cystic tumors of the spleen, to assess the possibility of differential diagnosis of individual morphological forms according to ultrasound data.Materials and methods. 323 patients with cysts and cystic tumors of the spleen from 15 to 77 years old (men – 105 (32.5%); women – 218 (67.5%) were treated at A.V. Vishnevsky National Medical Research Center of Surgery for the period from 1980 to 2020. All patients underwent ultrasound during examination. Surgical treatment was carried out in various ways – (85.1%), when making a preoperative diagnosis of an uncomplicated spleen cyst of small size, dynamic observation was carried out (verification by puncture biopsy data).Results. Morphological verification of cysts and cystic tumors of the spleen was presented as follows (taking into account possible difficulties in identifying the epithelial lining): true cyst – 182 (56.4%); dermoid cyst – 3 (0.9%) (malignant – in 1 case); pseudocyst – 16 (5.0%); pancreatogenic – 34 (10.5%); echinococcus – 52 (16.1%); lymphangioma – 24 (7.4%); lymphoma – 10 (3.1%); ovarian cancer metastasis – 2 (0.6%). The article describes the ultrasound signs of the above forms of the lesions with an emphasis on the complexity of diagnosis.Conclusions. Primary and parasitic spleen cysts are well differentiated according to ultrasound; false cysts of the spleen, depending on the cause of their occurrence, can create difficulties in their identification and differentiation (they require careful dynamic control); cystic tumors of the spleen should be differentiated from malignant tumors and metastases of a cystic structure, as a result of which such vigilance should always be present when they are detected.

The immediate and long-term results of treatment of 30 patients with severe pain syndrome of the lumbar region, who underwent operations on denervation of DOS, were studied. The aim of the study was to evaluate the effectiveness of minimally invasive technologies for the treatment of pain in the lumbar region (denervation of DOS), to study the near and distant results of these treatment methods. Denervation DOS is an effective minimally invasive method for the treatment of facet syndrome caused by spondylarthrosis. It allows in the early and distant postoperative periods to significantly reduce the pain syndrome and improve the quality of life of patients.

Abstract Purpose Despite primary conservative therapy for Crohn’s disease, a considerable proportion of patients ultimately needs to undergo surgery. Presumably, due to the increased use of biologics, the number of surgeries might have decreased. This study aimed to delineate current case numbers and trends in surgery in the era of biological therapy for Crohn’s disease. Methods Nationwide standardized hospital discharge data (diagnosis-related groups statistics) from 2010 to 2017 were used. All patients who were admitted as inpatient Crohn’s disease cases in Germany were included. Time-related development of admission numbers, rate of surgery, morbidity, and mortality of inpatient Crohn’s disease cases were analyzed. Results A total number of 201,165 Crohn’s disease cases were included. Within the analyzed time period, the total number of hospital admissions increased by 10.6% (n = 23,301 vs. 26,069). While gender and age distribution remained comparable, patients with comorbidities such as stenosis formation (2010: 10.1%, 2017: 13.4%) or malnutrition (2010: 0.8%, 2017: 3.2%) were increasingly admitted. The total number of all analyzed operations for Crohn’s disease increased by 7.5% (2010: n = 1567; 2017: n = 1694). On average, 6.8 ± 0.2% of all inpatient patients received ileocolonic resections. Procedures have increasingly been performed minimally invasive (2010: n = 353; 2017: n = 687). The number of postoperative complications remained low. Conclusion Despite the development of novel immunotherapeutics, the number of patients requiring surgery for Crohn’s disease remains stable. Interestingly, patients have been increasingly hospitalized with stenosis and malnutrition. The trend towards more minimally invasive operations has not relevantly changed the rate of overall complications.

Abstract Background Spondylodiscitis is an unusual infectious disease, which usually originates as a pathogenic infection of intervertebral discs and then spreads to neighboring vertebral bodies. The objective of this study is to evaluate percutaneous debridement and drainage using intraoperative CT-Guide in multilevel spondylodiscitis. Methods From January 2002 to May 2017, 23 patients with multilevel spondylodiscitis were treated with minimally invasive debridement and drainage procedures in our department. The clinical manifestations, evolution, and minimally invasive debridement and drainage treatment of this refractory vertebral infection were investigated. Results Of the enrolled patients, the operation time ranged from 30 minutes to 124 minutes every level with an average of 48 minutes. Intraoperative hemorrhage was minimal. The postoperative follow-up period ranged from 12 months to 6.5 years with an average of 3.7 years. There was no reactivation of infection in the treated vertebral segment during follow-up, but two patients with fungal spinal infection continued to progress by affecting adjacent segments prior to final resolution. According to the classification system of Macnab, one patient had a good outcome at the final follow-up, and the rest were excellent. Conclusions Minimally invasive percutaneous debridement and irrigation using intraoperative CT-Guide is an effective minimally invasive method for the treatment of multilevel spondylodiscitis.

Image-guided percutaneous drainage is an excellent minimally invasive method for dealing with infectious complications in the pediatric population. A thorough understanding of drainage procedures in children can often lead to improved patient outcomes. Indications for percutaneous drainage will be reviewed, including abscesses related to appendicitis, post-surgical abscess formation, and abscesses related to Crohn's disease. This pictorial essay will help the radiologist better understand the common etiologies of abscesses in children that may require percutaneous drainage, the special considerations for catheter placement, patient preparation, and anesthesia or sedation issues unique to the pediatric population.

AbstractObjectives:This study assessed the utility of current sialendoscopes in the paranasal sinuses in a cadaveric model and evaluated novel uses for sialendoscopes.Methods:Currently available sialendoscopes were used for visualisation and performing interventions in the paranasal sinuses. Ten cadaver heads were studied before and after dissection. Outcomes included ostia identification, sinus cannulation, success of mucosal biopsy collection and image clarity.Results:Marchal and Erlangen sialendoscopes were found to be effective for both visualising and cannulating the sphenoid sinuses before and after dissection. Both types demonstrated poor maxillary ostia visualisation without dissection, but did allow treatment after antrostomy. Larger diameter sialendoscopes were associated with the lowest image distortion during maxillary ostia assessment. Mucosal biopsy collection within the sphenoid sinus, but not in the maxillary sinus, was possible before dissection.Conclusion:Sialendoscopes can be used for visualisation and performing interventions in the sinonasal cavity, but their utility is mainly limited to the sphenoid sinus. They may be considered a minimally invasive method for drug delivery and/or biopsy collection in the post-operative setting for all sinuses. Design improvements are suggested.

We were asked to consider differential diagnosis. We decided that it really is different from the other diagnostic modalities and cannot be treated in the same way as, for example, global or neuropsychological measures. In the context of this meeting, we believed it would be appropriate to consider clinical criteria. Thus, clinical criteria for the dementia syndrome as well as for specific diseases were discussed. We recognized that in the future, an increasing number of patients will present with cognitive impairment who do not fulfill the clinical criteria for dementia. These patients may alternatively have an isolated memory impairment syndrome. Nevertheless, a diagnosis will still need to be made in these patients, at least in terms of the underlying molecular pathology, in order to implement potential treatments.

We report two cases of neuromyelitis optica spectrum disorder with hypoglossal nerve involvement resulting in a wasted tongue associated with other brainstem symptoms of hypogeusia, hypersalivation, hiccough, increased sweating, hyperemesis and myelitis (in the second patient). This occurred due to involvement of the hypoglossal, tractus solitarius and dorsal vagal nuclei. Though the myelitis and other brainstem signs recovered the hypoglossal nerve involvement resulting in a unilateral wasted tongue did not. It is important to consider neuromyelitis optica and its spectrum disorders in the differential diagnosis of a wasted tongue though its occurrence is rare.
