Abstract The aim of this work was to study the effect of the reduced acquisition time of PET 11C-MET examination on the quality of primary brain tumors differential diagnosis. 57 patients with histologically verified diagnoses were recruited (glioblastoma n=20, anaplastic astrocytoma n=11, diffuse astrocytoma n=11, oligodendroglioma n=9 and anaplastic oligodendroglioma n=6). The scan time was varied in the range of 2-20 min. Our study demonstrated that in the case of intravenous administration of 11C-MET simultaneously with the start of scanning, the quality of primary gliomas differential diagnosis does not depend on the scan time. Therefor it becomes possible increasing the number of patients and reducing the acquisition time. The T/N60 ratio (T/N ratio measured in the first 60 seconds after 11C-MET intravenous injection) is equally successful parameter for glioma differential diagnosis as the traditional T/N ratio.

Abstract. This article concerns the utility of ego psychoanalytic perspectives in Rorschach interpretation. Psychoanalytic ego psychology focuses on how people cope with events in their lives and how effectively they can meet challenges to their sense of well-being. The way people deal with experienced distress constitutes their defensive style and determines to a large extent what kind of person they are. Adequate defenses against anxiety promote comfortable and productive adjustment, whereas ineffective defenses typically cause adjustment difficulties and susceptibility to psychological disorders. In Rorschach assessment, the nature and effectiveness of a person’s defensive style can often be identified with a sequence analysis that integrates the structural, thematic, and behavioral features in the protocol. In particular, the sequential quality of responses, especially preceding and following instances of cognitive slippage, can help identify causes of upsetting concerns, defensive efforts to alleviating these concerns, and the adequacy of these defensive efforts in restoring equanimity. This interpretive process is illustrated with attention to implications for differential diagnosis and treatment planning in the Rorschach protocol of a 20-year-old suicidal woman.

Data Screening

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.

Exercise training (ET) is now recommended as an important component of a comprehensive approach to patients with heart failure (HF). Despite the existence of proven benefits of ET, many HF patients remain physically inactive. Introducing telerehabilitation (TR) may eliminate most of the factors that result in the currently low number of patients undergoing outpatient-based rehabilitation programmes and thus increase the percentage of those who will undergo cardiac rehabilitation. Despite the fact that TR is highly applicable and effective, there are few papers dedicated to the study of TR in HF patients. Until recently, only a couple of home rehabilitation-monitoring models have been presented, from the simplest, i.e. heart rate monitoring and transtelephonic electrocardiographic monitoring, through to the more advanced tele-electocardiogram (tele-ECG) monitoring (via a remote device) and realtime electrocardiographic and voice transtelephonic monitoring. It seems the last two are the most useful and reliable. Based on published studies, TR in HF patients could be equally effective as and provide similar improvements in health-related quality of life to standard outpatient cardiac rehabilitation. In addition, adherence to cardiac rehabilitation seems to be better during TR. Due to disease-related limitations, TR seems to be a viable alternative for comprehensive cardiac rehabilitation in HF patients. Further studies are needed to confirm the utility of this type of rehabilitation in routine clinical practice, including its cost-effectiveness. Because of the diversity of technological systems, it is necessary to create a platform to ensure compatibility between the devices used in telemedicine.

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.

Adamantinomatous Craniopharyngioma

OBJECTIVEPediatric adamantinomatous craniopharyngiomas (ACPs) are histologically benign brain tumors that confer significant neuroendocrine morbidity. Previous studies have demonstrated that injury to the hypothalamus is associated with worsened quality of life and a shorter lifespan. This insight helps many surgeons define the goals of surgery for patients with ACP. Puget and colleagues proposed a 3-tiered preoperative and postoperative grading system based on the degree of hypothalamic involvement identified on MRI. In a prospective cohort from their institution, the authors found that use of the system to guide operative goals was associated with decreased morbidity. To date, however, the Puget system has not been externally validated. Here, the authors present an interrater reliability study that assesses the generalizability of this system for surgeons planning initial operative intervention for children with craniopharyngiomas.METHODSA panel of 6 experts, consisting of pediatric neurosurgeons and pediatric neuroradiologists, graded 30 preoperative and postoperative MRI scans according to the Puget system. Interrater reliability was calculated using Fleiss’ κ and Krippendorff’s α statistics.RESULTSInterrater reliability in the preoperative context demonstrated moderate agreement (κ = 0.50, α = 0.51). Interrater reliability in the postoperative context was 0.27 for both methods of statistical evaluation.CONCLUSIONSInterrater reliability for the system as defined is moderate. Slight refinements of the Puget MRI grading system, such as collapsing the 3 grades into 2, may improve its reliability, making the system more generalizable.

Patients With Epilepsy

Gliomas make up about 8 cases per 100,000 population and the number of patients with this disease is only increasing. There can be not only various types of neurological deficits among the symptoms, but also personal and emotional changes, that seriously affects the quality of life. The modern model of health care includes not only recovery of the patient’s physical functions, but also his or her psychosocial well-being. In particular, the assessment and study of the characteristics of health-related quality of life, as well as cognitive functions in patients with gliomas, is increasingly recognized as an important criterion when considering the effectiveness of treatment. To date, the features of health related quality of life and cognitive functions of patients with epilepsy and acute cerebral circulation disorders have been studied sufficiently, and, as a result, techniques have been developed that accurately assess the QOL and CF in patients with these diseases. These are QOLIE-31 and QOLIE-AD-48 questionnaires for patients with epilepsy. This is the National Institutes of Health Stroke Scale (NIHSS), Orgogozo stroke scale (OSS), World Federation of Neurological Surgeons (WFNS) scale for the clinical assessment of subarachnoid hemorrhage (SAH) for patients with acute cerebrovascular accident. At the same time, there are no generally accepted methods for assessing quality of life and neurocognitive functions that are sensitive to changes in the condition of patients with gliomas in the early postoperative period by the time of discharge from the hospital. As a result, there is no systematic information on the dynamics of the quality of life of such patients, their neurocognitive functioning. The purpose of this article was to study the literature on QOL and CF in patients affected by neurological and neurosurgical disorders for the further selection of optimal methods for assessing dynamics of the condition of patients with glial brain tumors before and after surgery. At the moment, such requirements are only partially met by the EORTC QLQ-C30 questionnaire and its application EORTC QLQ-BN20.

The article presents the results of a prospective controlled parallel clinical study of a new modification of laparoscopic antireflux surgery in the treatment of gastroesophageal reflux disease in combination with a hiatal hernia compared with laparoscopic Nissen fundoplication in terms of assessing quality of life after surgery. Clinical and instrumental examination of patients was carried out a year after surgical interventions. In accordance with the results of instrumental examination after surgery, the proposed modification of laparoscopic partial fundoplication is not inferior to laparoscopic Nissen fundoplication both, in terms of relief of reflux esophagitis symptoms and in relation to the recurrence of hiatal hernia. Clinical monitoring indicates a significantly higher quality of life for patients after the modified antireflux surgery, which is associated with a number of factors. The implementation of this fundoplication led to a decrease in the number of patients with complaints of dysphagia, the development of which is directly related to the surgery performance, as well as to a statistically significant reduction of bloating in the upper abdomen. Another advantage of the modified surgery is a significantly smaller number of cases of gas-bloat syndrome. In addition, the disorders developing in the framework of the gas bloat syndrome after laparoscopic Nissen fundoplication are more severe.
