The review of literature deals with the current classification of the biliary atresia, presents the authors’ opinion considering a technique of theKasaiprocedure, and displays modern modifications of portoenteroanastomosis estimating their effectiveness. PubMed database and Google Scholar search system were used to search for primary terms. Survival of children with this pathology was analyzed depending on theKasaitechnique, anatomical form, terms of portoenteroanastomosis and importance of early diagnosis of this pathology.

The charts of 15 patients with foregut cysts were reviewed. The lesions were intrathoracic in 14 patients and in the cervical area in one child. The importance of early diagnosis and surgical management is stressed. In untreated infants with foregut cysts, severe progressive and life-threatening airway obstruction may develop. Since the symptoms of this congenital lesion may simulate other more common diseases of the tracheobronchial tree and esophagus, the physician should become familiar with this disease entity so that proper diagnosis and surgical treatment will not be delayed. The study includes symptomatology, methods of diagnosis, pathologic findings and classification of the cysts.

The article analyzes and presents data for the last 70 years from the PubMed database on endometrial hyperplasia (EH), which is one of the leaders in the structure of gynecological diseases and the main predictor of endometrial cancer (EC). The chronicle of the EH classification is highlighted with a focus on changing the designation and relevance of adenomatous EH. It is shown how the current classification of EH, due to the fact that a large number of synonyms is limited by two options, allows to maximize the reproducibility of the diagnosis, improve the interaction of the obstetrician-gynecologist with the pathologist and reduce the treatment inefficiency. The results of modern studies on the prevalence and risk factors of EH and EC differ from previously accepted ones and destroy the Bohman triad. The risks of EH development with tamoxifen and menopausal hormone therapy are determined. The data of current research methods aimed at the diagnosis of EH and EC are indicated. The differences in etiopathogenesis, prevalence, diagnosis, risk factors for development and progression to the malignant process presented in the review represent two types of EH (without atypia and with atypia) as completely different endometrial diseases included in the same classification.

Over Time

The analysis of literature data (PubMed database, Google Scholar) is presented, devoted to the problematic study of the cryptorchidism's terminology and classification. The literature periodically calls for systematization terms used in describing the position undescended testis. Due to the confusion in terminology, it is difficult to generalize and analyze the data obtained. The same position of the undescended testis is described differently by various authors, which led to the appearance of many authors' cryptorchidism classifications at the beginning of the 21st century. This review of the literature states the fact that, over time, no consensus has been found regarding the classification of undescended testicles. Currently, there is a need to generalize the available data to select the optimal treatment algorithm. If the treatment algorithm for the palpable testicles is well studied, then the choice of a treatment method for the cryptorchidism non-palpable forms remains debated in the surgical community.

Today, around 50 million people worldwide suffer from cataracts, more than a half of them need surgical treatment. High prevalence of this pathology in Ukraine, the need to improve the provision of ophthalmic care to patients, and the reform of the health care system have made the research relevant. Concomitant diseases and special conditions of the eye increase the risk of intra− and postoperative complications, worsen the functional parameters of patients after surgery. In order to develop a unified approach to the treatment of complicated cataracts based on diagnostically related groups of patients, a retrospective analysis of case histories of patients with different variants of complications related to the condition of the lens itself, its ligament apparatus and other structures of the eye was conducted. In each case, the surgeon has to choose the appropriate modification of cataract phacoemulsification surgery. The study proposed the classification of cataract phacoemulsification modifications on the basis of the techniques and the sequence of operation stages, taking into account the classification of the degrees of turbidity of the lens, proposed by L. Buratto. It has been noted that in complicated cases, according to the indications of the patient, surgery may be performed on several modifications of cataract phacoemulsification. The developed classification made it possible to generalize the various variants of pathology and greatly facilitate the choice of tactics of surgical treatment in complicated cataracts. It can be used not only for practical application, but also for improving the qualification of trained professionals. The prospect of further research is to identify contraindications for outpatient treatment of the patients with complicated cataracts. Key words: cataract complication, classification of phacoemulsification modifications, diagnostically related groups.

Abstract Background Commelinaceae (Commelinales) comprise 41 genera and are widely distributed in both the Old and New Worlds, except in Europe. The relationships among genera in this family have been suggested in several morphological and molecular studies. However, it is difficult to explain their relationships due to high morphological variations and low support values. Currently, many researchers have been using complete chloroplast genome data for inferring the evolution of land plants. In this study, we completed 15 new plastid genome sequences of subfamily Commelinoideae using the Mi-seq platform. We utilized genome data to reveal the structural variations and reconstruct the problematic positions of genera for the first time. Results All examined species of Commelinoideae have three pseudogenes (accD, rpoA, and ycf15), and the former two might be a synapomorphy within Commelinales. Only four species in tribe Commelineae presented IR expansion, which affected duplication of the rpl22 gene. We identified inversions that range from approximately 3 to 15 kb in four taxa (Amischotolype, Belosynapsis, Murdannia, and Streptolirion). The phylogenetic analysis using 77 chloroplast protein-coding genes with maximum parsimony, maximum likelihood, and Bayesian inference suggests that Palisota is most closely related to tribe Commelineae, supported by high support values. This result differs significantly from the current classification of Commelinaceae. Also, we resolved the unclear position of Streptoliriinae and the monophyly of Dichorisandrinae. Among the ten CDS (ndhH, rpoC2, ndhA, rps3, ndhG, ndhD, ccsA, ndhF, matK, and ycf1), which have high nucleotide diversity values (Pi > 0.045) and over 500 bp length, four CDS (ndhH, rpoC2, matK, and ycf1) show that they are congruent with the topology derived from 77 chloroplast protein-coding genes. Conclusions In this study, we provide detailed information on the 15 complete plastid genomes of Commelinoideae taxa. We identified characteristic pseudogenes and nucleotide diversity, which can be used to infer the family evolutionary history. Also, further research is needed to revise the position of Palisota in the current classification of Commelinaceae.

Controversial Aspect

Hemocytes, the cells present in the hemolymph of insects and other invertebrates, perform several physiological functions, including innate immunity. The current classification of hemocyte types is based mostly on morphological features; however, divergences have emerged among specialists in triatomines, the insect vectors of Chagas’ disease (Hemiptera: Reduviidae). Here, we have combined technical approaches in order to characterize the hemocytes from fifth instar nymphs of the triatomine Dipetalogaster maxima. Moreover, in this work we describe, for the first time, the ultrastructural features of D. maxima hemocytes. Using phase contrast microscopy of fresh preparations, five hemocyte populations were identified and further characterized by immunofluorescence, flow cytometry and transmission electron microscopy. The plasmatocytes and the granulocytes were the most abundant cell types, although prohemocytes, adipohemocytes and oenocytes were also found. This work sheds light on a controversial aspect of triatomine cell biology and physiology setting the basis for future in-depth studies directed to address hemocyte classification using non-microscopy-based markers.
