Currently, in most clinical cases, the patient has a concomitant or combined pathology described by the terms "polymorbidity" (in the absence of a pathogenetic relationship) and "comorbidity" (in the presence of a pathogenetic relationship) between various diseases and pathological conditions. In the system of relationships between an internist and physicians of other specialties, the least studied aspects of their clinical interaction with a dentist. At the same time, often the reason for a patient's visit to the dentist is the presence of somatic pathology, and for the most part, not completely healthy patients come to the dentist's appointment, whose problems are limited to the oral cavity. On the other hand, the presence of certain changes in organs and tissues of the oral cavity and the advice of a dentist can help the internist in the diagnosis and adequate treatment of the patient. The first part of the presented review examines possible changes in the organs and tissues of the oral cavity in patients with diseases of the cardiovascular system and diseases of the digestive system. The second part of the review is devoted to the analysis of the possible effect on the organs and tissues of the oral cavity of drugs used to treat cardiovascular and gastroenterological diseases.

Abstract Frequency and arm-chair linguistics. A Frisian linguist looks back on Dutch Linguistics and on himselfIn this contribution I focus on a paper written by Maarten Lemmens on progressive constructions, which appeared in Dutch Linguistics (2015). This paper illustrates the usefulness of frequency in linguistic research convincingly. Additionally I discuss the tension within generative grammar between vision on the one hand and a methodologically adequate treatment of data on the other hand. Finally, I look back on my own activities as a linguist, presenting some personal thoughts about the question what the usefulness is of mediocrity.

Observations are described of the incidence among Caucasians and Negroes of the blood factors RhA, RhB and RhC which occur associated with the Rh0 factor in typical Rh-positive blood. The antiserums used for the tests were derived from Rh-positive patients who had had hemolytic transfusion reactions or erythroblastotic babies. Among a large series of individuals, it was found that only rarely is any of the blood factors RhA, RhB, or RhC lacking from "standard" Rh0-positive blood. On the other hand, about half of the specimens of Rh0 variant blood lack one or more of the factors RhA, RhB, and RhC, which, when present in such blood, are also almost always variants. Judging from the incidence of specimens lacking one or more of these factors, RhA, RhB, and RhB appear to be relatively independent of one another despite their association with blood factor Rh0. Tests for factors RhA, RhB, and RhC distinguish new rare varieties of Rh and ℜh agglutinogens, each genetically determined by corresponding allelic genes. There is no doubt that more clinical cases will be found in which sensitized Rh-positive individuals have antibodies resembling anti-Rh0 in specificity. Four such cases have already been studied by the present authors, and in each case the antibodies were shown to be different from anti-Rh0 in specificity. Since they were also different from one another, they have been assigned the symbols anti-RhA, anti-RhB, anti-RhC, and anti-RhD, respectively, the first three being the antiserums used in the present study. Obviously, in order to avoid confusion of nomenclature, the specificity of antiserums from other similar cases will have to be compared with anti-RhA, anti-RhB, anti-RhC, and anti-RhD and shown to be different from all four, as well as anti-Rh0, before a distinctive symbol is assigned to them.

Oxidative stress has been implicated in many chronic diseases. However, antioxidant trials are so far largely unsuccessful as a preventive or curative measure. Chronic low-grade inflammatory process, on the other hand, plays a central role in the pathogenesis of a number of chronic diseases. Oxidative stress and inflammation are closely related pathophysiological processes, one of which can be easily induced by another. Thus, both processes are simultaneously found in many pathological conditions. Therefore, the failure of antioxidant trials might result from failure to select appropriate agents that specifically target both inflammation and oxidative stress or failure to use both antioxidants and anti-inflammatory agents simultaneously or use of nonselective agents that block some of the oxidative and/or inflammatory pathways but exaggerate the others. To examine whether the interdependence between oxidative stress and inflammation can explain the antioxidant paradox we discussed in the present review the basic aspects of oxidative stress and inflammation and their relationship and dependence.

Research on the health of mammals invariably shows how dynamic immunology is and how the role of many elements and immune processes of the macroorganism, developed in the process of evolution in protecting against threats, including infections, is changing. Among these elements conditioning the homeostasis of the macroorganism are mitochondria, PRR receptors (pattern recognition receptors) and the phenomenon of autophagy. In the context of physiological and pathological states in the body, mitochondria perform various functions. The primary function of these organelles is to produce energy in the cell, but on the other hand, they are heavily involved in various cellular processes, including ROS production and calcium homeostasis. They are largely involved in the activation of immune mechanisms during infectious and non-infectious conditions through mtDNA and the mitochondrial MAVS protein. Mitochondrial involvement has been also determined in PRR-related mechanisms as mtDNA has the ability to directly stimulate TLRs. On the other hand, mitochondria are also associated with apoptotic cell death and autophagy.

THE collar-cells are in normal life short and barrel-shaped, with separated cylindrical collars, which are never united. In certain pathological conditions, probably connected with suffocation, they elongate very greatly, diminishing in the diameter of their upper part, or "collum;" and in some species, though not in Sycon compressum, the collars may then come into contact. In certain other pathological conditions the collar is lost, though apparently it can be regenerated. These metamorphoses appear unconnected with the ingestion of food, which also was not found to induce any migration of the collar-cells. On the other hand, migration seemed to occur under exceptionally unhealthy conditions. The collar is made up of (in Sycon compressum) about thirty parallel rods united by a film of some other substance. The flagellum is intimately connected with the nuclear membrane. There is an interstitial substance between the bodies of the cells. The area inside the collar appears to be provided with a sphincter membrane. Cells preserved and cut by the paraffin method show an average contraction of 5:4 linear in the best sections. In most preparations this contraction is uneven, producing Sollas's membrane and other fictitious appearances.

Hypoxia, which could be defined as the level of oxygen tension in the body that is below the normal physiological value, is a process that is often observed in several diseases and occurs in most malignant tumors. On the other hand, in hypoxia several pathological conditions could occur, which could be caused by external and internal factors. During carcinogenesis, hypoxia may promote metastasis and an unfavorable prognosis. When infected with COVID-19, there is a «silent hypoxia», which could asymptomatically destroy the body. The review is devoted to hypoxia’s role in the development of some pathological conditions and malignant tumors.

Increased Homocysteine Levels (HHcy) is an independent risk factor for atherosclerosis. On the other hand, hydrogen sulfide (H2S) exerts a protection against cardiovascular injuries. On the contrary, accumulating evidences showed that downregulation of defective catabolism of HHcy, with reduced H2S synthesis, is involved in the pathogenesis of a variety of cardiovascular diseases. In that occurrence, the detrimental actions on cardiovascular structures performed by HHcy are added to the negative consequences of reduced H2S (in part unlike each HHcy) on cardiovascular system. Therefore, when the reduced re-methylation pathway of Hcy towards Met (resulting in HHcy) is contemporarily added to the decreased trans-sulfuration pathway (inducing a reduction of H2S synthesis) cardiovascular impairment significantly increases.

The clinical records of 44 children (34 girls and 10 boys) with ureteroceles, seen at the Squier Urological Clinic during a period of 27 years, have been reviewed and the findings tabulated. Of the 44 cases, 38 were found clinically among some 3,800 new pediatric urologic admissions, an incidence of 1 in every 100 new pediatric urologic patients. The other six cases were found incidentally at necropsy at the Babies Hospital, among 3,200 consecutive necropsies, i.e., one in every 500 general pediatric necropsies. Among the 38 clinical cases of ureteroceles 85% had severe dilatation of one or more upper urinary tract units, 25% of which had also evidence of bladder-neck obstruction caused by the ureterocele. In the remaining 15%, the dilatation was confined to one upper urinary tract unit and was minimal or mild. As expected, large ureteroceles were present in those patients with unilateral or bilateral duplication of the upper urinary tract, and caused severe hydroureteronephrosis, while small ureteroceles were usually seen in children with single upper tracts, and produced minimal or mild ureteropyelic dilatation. Unilateral or bilateral duplication of the upper urinary tracts was also present in 75% of the 38 cases and in 90% of those who had large ureteroceles. In all children with duplicated urinary tract who had ureteroceles, the latter were always found involving the lower ureteral ostium; i.e., the one which drained the upper kidney. There was no characteristic clinical picture caused by this condition, but fever, pyuria and recurrent abdominal pain were usually present. Urography was helpful in establishing a correct diagnosis of ureterocele in about 50% of all cases irrespective of the status of the ureterocele and quality of the film. Cystoscopy was only done whenever the diagnosis was not previously established by urography on in difficult situations such as those seen in collapsed ureteroceles. In this latter group the cystoscopic findings were bizarre and at times misleading. Transcystoscopic excision of the ureterocele was carried out in many cases but with good results only in those children with small uneteroceles and minimal to mild dilatation of the upper urinary tract. Nephrectomy or heminephroureterectomy was the treatment of choice in children with large ureteroceles and severely dilated upper urinary tracts. At times, multistaged procedures were necessary in order to achieve a satisfactory result, the initial step being a simple cystoscopic fulguration or a suprapubic excision, or uncapping of the ureterocele. Whenever the general condition of the child was satisfactory, the treatment consisted of attempts at repair of the anomaly, when feasible, or radical excision not only of the uneterocele but also of the involved renoureteral unit or units if the remaining kidney was considered sufficient to support a useful life. Finally, a prolonged course with antibiotics and chemotherapeutic agents usually followed surgery, in order to control the concomitant infection of the urinary tract. Ureteroceles in children were found to be apt to produce serious hydrodynamic disturbances of the upper urinary tracts and sometimes obstruction of the bladder neck. Furthermore, bizarre clinical syndromes, misleading cystoscopic findings and confusing urographic pictures were present in about 30% of the 38 clinical cases of ureterocele in children seen at the Squier Urological Clinic and described in this report. In these cases the correct diagnosis was initially overlooked or delayed, adequate treatment postponed or incompletely carried out, and the results obtained were poor. On the other hand, satisfactory result were usually achieved in the remaining 70% of the cases in which a correct diagnosis was established early and adequate treatment instituted. For these reasons, familiarization with the various clinical, cystoscopic and urographic findings encountered in children with ureterocele is important in order to bring about early diagnosis and treatment of this condition.

Improvement of the course on the topic "Specialization on reflexology" of the lecture material on the theme "Use of reflexotherapy as part of complex therapeutic measures in cosmetology" has helped to reduce the pharmacological burden on patients and minimize the possibility of development of complications and side effects of pharmacotherapy. On the other hand, application in the structure of therapeutic measures of acupuncture will undoubtedly increase the effectiveness of therapy of a fairly wide range of pathological conditions in dermatology.

Taking inspiration from Frommer, this paper is part of a shift towards incorporating death as a defining psychic issue. With a sense that I am surrounded by death, the author presents two brief vignettes of clinical cases to illustrate the impact of the therapist’s relationship with death on the therapeutic process. Each case shows a different level of engagement with the client when the focus is on death-talk, and reflects, on the one hand, the therapist’s ability and readiness to work with death as an object of analysis, and on the other hand, the therapist’s lack of processing of experiences of death of others, and the resultant failure to successfully work with death in analysis. The one case is arguably more successful therapeutically than the other, and highlights some issues that come into play in the light of the therapist’s relationship with death. These issues are: i) the importance of the therapist’s development with regards to processing experiences of death and dying cannot be underestimated when working with death as an object of scrutiny; ii) empathy remains core to the process and getting in touch with how the client experiences the death of the other. Without recognition, however, no (grief) work can begin. The therapist needs to psychologically recognise the other to be able to connect to, and empathize with, the clients process; iii) the impact of the death of the other often transforms into the work of the impact of the death of self; iv) if clients have a sense that the therapist knows what they are speaking about because the therapist has done some of the work of making meaning of death, clients may feel more confident in working with death as an object of analysis.
