The aim of the study was to evaluate the informative value of various diagnostic methods for spontaneous drainage of the pancreatic pseudocyst into the stomach.Materials and methods: based on the clinical observation of a patient who received complaints of pain in the epigastrium, an episode of melena, after suffering acute pancreatitis several years ago with the development of pancreatic necrosis with an outcome in the cyst of the tail of the pancreas, drainage of the omentum bag. The patient underwent a comprehensive laboratory and instrumental examination.Results: ultrasound, endoscopic examination, MSCT suspected a malignant process in the stomach with ulceration and germination into the pancreas. After performing endoscopic ultrasonography, it was possible to differentiate the layers of the formation and make the correct diagnosis, which was confirmed by subsequent MSCT with oral contrast.Conclusions: a spontaneously opened pancreatic pseudocyst in the lumen of the stomach is a rare and difficult to diagnose disease. An integrated approach, including endoscopic, ultrasound, X-ray, and laboratory methods of investigation when compared with the clinical picture, allows us to verify the formation of the pancreas.

A cough lasting longer than 4-8 weeks, defined as chronic cough, always requires thorough diagnostic evaluation. In addition to detailed history-taking and physical examination, simple and available diagnostic methods, such as chest x-ray and spirometry, should be performed. They may be helpful tool to establish the underlying cause of cough. Many younger children may have difficulties in performing the forced expiratory maneuvers and fulfilling repeatability criteria for spirometry. The disturbances resulting from insufficient cooperation should be considered in interpratation of the obtained results. The shape of the flow-volume curve, which suggests upper or central airways obstruction, can not be ignored and always requires further investigation for diagnosis of respiratory pathology. The chest x-ray is the most frequently performed radiographic examination in children. Accurate interpretation is essential in reaching a correct diagnosis. Mediastinal widening on the chest x-ray in children can occur due to a large variety of causes. The normal thymus can take on a variety of sizes and shapes and still be considered normal in the first few years of life. In older children mediastinal widening should be differentiated from mediastinal masses. Lymph node enlargement represents a frequent cause, usually as a result of infection or malignancy. The article reports a case of a 12-year-old boy with chronic cough, mediastinal widening on the chest X-ray and abnormal spirometry results, who was finally diagnosed with stage III Hodgkin’s lymphoma.

Abstract: Internal resorption is an asymptomatic condition in teeth seen with past history of injury. In the crown it has a clinical observation of pink mark. It is diagnosed by chance on an x-ray examination. Primal detection and resorption treatment improves prognosis of the condition. Resorption can be broadly classified into normal physiological or pathological process associated with extensive damage to hard structures of tooth such as dentin, cementum and bone. Proper diagnosis of resorption and differentiation of resorption from internal and external resorption by radiographic presentation and the correct diagnosis and treatment planning improves the prognosis of the condition. Untreated cases will cause loss or early exfoliation of the afflicted tooth [1].

Progressive Muscular Dystrophy

Limb-girdle muscular dystrophy is a genetically heterogeneous group of disorders that are characterized by slowly progressing muscle weakness and presents a diagnostic problem in the neurological practice. The combination of clinical, radiological, and laboratory methods of examination plays an important role in referring the patient to genetic counseling and making the correct diagnosis. Magnetic resonance imaging of muscles is increasingly used to give clues in the primary muscle damage diagnosis, based on specific patterns of muscle lesion. The article provides two clinical cases as an example of an integrated approach to the diagnosis of progressive muscular dystrophy using genetic analysis and magnetic resonance imaging of muscles

Gastric Tumors

One hundred patients, suspected to be affected with gastric cancer, were examined at first roentgenologically and afterwards with a new gastroscope, the fiberscope. A correct diagnosis was performed by the radiologist in 79 patients, by the endoscopist in 87, and with the combined examinations in 91 cases. From the results obtained in this study, it appears that gastroscopy is specially indicated when x-ray findings are uncertain or when there is not agreement between radiological conclusions and clinical signs. In addition, the gastroscopic examination may be able to reveal a neoplastic degeneration of a gastric ulcer, still unsuspected by the radiologist. Gastroscopy has no advantages in the exploration of intramural lesions, but it is sometimes useful in large tumors, already radio-logically diagnosed, in order to discover distant intraluminal metastases.

The article describes various methods of treatment of achalasia, for example, endoscopic balloon pneumatic dilation that extends the lower esophageal sphincter, injection of botulinum toxin that decreases cardia tone, minimally invasive endoscopic methods in combination with medicinal therapy, and surgical treatment of patients at the fourth stage of the disease that promotes good or satisfactory clinical results in 98.2% of patients. The present study also introduces an optimal algorithm for the examination of patients with suspected achalasiocardia. X-ray diagnostics and endoscopic examination were used to verify the diagnosis. All these methods ensure timely and correct diagnosis, determining also the stage of the disease development. Stage-wise diagnostics in Russia are mostly based on the classification suggested by B.V. Petrovsky in 1962. This classification is founded upon X-ray examination of the esophagus due to its simplicity and availability. The article also presents a completely novel approach for the treatment of achalasiocardia in Russia, that is, peroral endoscopic myotomy (POEM).This method of endoscopic operation has been used in our clinic since 2014 for adult patients, and in 2016, it has been for the first time in Russia performed on a child. A clinical example of achalasiocardia in a child is presented as well as diagnostic methods, medicinal treatment, and the use of balloon pneumatic dilation resulting in a recurrence that subsequently demanded peroral endoscopic myotomy. This minimally invasive endoscopic operation nowadays is highly effective and prospective for the treatment of achalasiocardia in both adults and children.

Diagnostic Difficulties

This work presents an analysis of x-ray, clinical, laboratory methods for the study of patients with pneumonia and central lung cancer, in order to study the main causes of diagnostic errors. It was established that the causes of diagnostic errors of patients with pneumonia and central lung cancer were the insufficient severity of the leading clinical signs of the course of the disease, the lack of an integrated approach in determining the volume and methods of examination, the inadequacy of accounting for the main radiological signs (localization, density, structure of formation, cavity of decay); lack of an algorithm in the stages of the diagnostic process and the late availability of specialized medical care.

Abstract An integrated approach was developed for investigation of thermal spray coatings with the amorphous-crystalline structure. The new approach combines methods of metallography, differential thermal and X-ray phase analysis, scanning electron microscopy and X-ray microanalysis. This makes it possible to reveal structural, phase and chemical heterogeneity, determine the degree of amorphization of coatings, temperature and heat of crystallization of the amorphous phase during heating. The new integrated approach was used to study amorphous-crystalline coatings of the Ni-P, Fe-Ni-B and Fe-B systems produced by thermal spraying.

Background. The article presents an observation of the clinical case of orthostatic hypotension that developed after an infection caused by the SARS-CoV-2 virus. The issues of etiology, pathogenesis, diagnosis are outlined. The complexity of diagnosis at the stage of clinical observation is due to the comorbidity of possible mechanisms and the difficulty of determining the primary factor. Taking into account the study of variants of direct and indirect action of this 2019-nCoV, the description of the clinical observation of orthostatic hypotension supplements the data on the spectrum of manifestations of this disease. Aim. Analysis of the clinical case of the development of orthostatic hypotension in the post-acute period of COVID-19. Material. When conducting a literature review on the selected topic, various sources were considered. The search depth was over 7 years. For the recruitment of literature, Internet platforms UpToDate, PubMed, Medscape were used. Russian and foreign sources were studied. Methods. Anamnesis collection, objective research, specialized tests, laboratory and instrumental research methods, study of disease history, literature sources on orthostatic hypotension and the effect of COVID-19 on the autonomic nervous system. Results. The analysis of this case with the determination of the leading mechanism of orthostatic hypotension is extremely difficult. Probably, there is a combination of factors: direct and indirect effects on the nervous system at COVID-19. The direct effect is associated with the interaction of the virus with the angiotensin converting enzyme 2 receptors in the nervous system, which causes a significant increase in the concentration of bradykinin and the development of hypotension. An indirect effect is due to both increased thrombus formation with the development of PE, and autonomic dysfunction, within the framework of secondary polyneuropathy of fine fibers. Conclusion. It is likely that in the near future the number of such patients in the practice of doctors will increase, therefore, timely and correct diagnosis of these conditions, with their careful management, will be the fundamental postulates in the recovery of patients. Drawing attention to this topic will possibly expand our understanding of the spectrum of complications of COVID-19 and will greatly complement the information available today.

AbstractDuring a study of the ore minerals belonging to the recently discovered Shuangjianzishan Ag–Pb–Zn deposit in NE China, we have discovered exceptional selenium enrichment in canfieldite (up to 11.6 wt.% of Se). Incorporation of Se into canfieldite has been investigated by an integrated approach using field emission scanning electron microscopy, electron microprobe and single-crystal X-ray diffraction. Canfieldite has been identified as one of the dominant Ag-bearing ore minerals in the studied deposit, which occurs mostly in slate-hosted vein type Ag–Pb–Zn ore bodies. Selenium is either homogeneously or, remarkably, heterogeneously distributed in the different canfieldite fragments studied. Chemical variations of Se are mostly attributable to a series of retrograde reactions resulting in diverse decomposition and exsolution of primary phases during cooling, or alternatively, related to influxes of Se-rich fluids during the formation of canfieldite. To evaluate the effects of the Se-for-S substitution in the structure, a crystal of Se-rich canfieldite [Ag7.98Sn1.02(S4.19Se1.81)Σ6.00] was investigated. The unit-cell parameters are: a = 10.8145(8) Å and V = 1264.8(3) Å3. The structure was refined in the space group F$\bar{4}$3m to R1 = 0.0315 for 194 independent reflections, with 20 parameters. The crystal structure of Se-rich canfieldite was found to be topologically identical to that of pure canfieldite. If the short Ag–Ag contacts are ignored (due to the disorder), the two Ag atoms in the structure can be considered as three-fold (Ag1) and four-fold (Ag2) coordinated. Tin adopts a regular tetrahedral coordination. As in the case of Te-rich canfieldite, the refinement of the site-occupancy factor indicates that Se is disordered over the three anion positions.

The study objective is to report a case of dynamic neuropathy of the common peroneal nerve at the level of the fibular head and to discuss diagnostic methods and neurosurgical treatment. Materials and methods. We report a case of dynamic neuropathy of the common peroneal nerve at the level of the fibular head in a female patient. The patient was treated in the Neurology Clinic of I.M. Sechenov First Moscow State Medical University. We analyzed clinical manifestations and compared them with the data described in research literature. Results. Upon admission, the patient complained of pain in the anterolateral surface of the right shin and in the dorsum of the foot during walking. At rest, the patient experienced no pain. We observed no motor or sensory disorders typical of nerve root disorders at the level of L5. Lasegue’s test was negative. The patient had a positive Tinel’s sign in the area of the right fibular head. In order to clarify the diagnosis, we performed a repeated extension test in the right ankle joint and it was positive. The patient underwent surgery that included peroneal nerve decompression and neurolysis at the level of the fibular head. In the postoperative period, the patient had complete pain relief. Conclusion. Due to the difficulties in the diagnostics of dynamic neuropathy of the common peroneal nerve, this disease is often mistaken for radiculopathy at the level of L5. Thorough clinical examination, testing for Tinel’s sign in the area of the fibular head, and repeated extension test in the ankle joint ensure the correct diagnosis and reduce the frequency of ineffective surgeries on the lumbar spine. Surgical decompression of the common peroneal nerve at the level of the fibular head with obligatory opening of the entrance to the nerve canal is an effective method of treatment in such patients.
