Measles, known from the early ages, is caused by a paramyxovirus. A Persian colleague named Rhazes (854-925 A.D.) was likely the first to distinguish smallpox from measles, this milder disease getting the name “morbilli” (little disease) from the Latin word morbus (disease). Being one of the most contagious infections, a measles-infected individual may on average transmit the virus to 12-18 susceptible persons from 3-4 days before to soon after first clinical symptoms appear. Essentially only Man’s (and some monkey species’) disease, measles is potentially eradicable by vaccination, provided vaccine uptake exceeds 95 % for a long enough time. This remains a challenge, and we likely will continue to have measles with us for a long time.

Introduction. The association between hydrocephalus and Chiari malformation (CM) has not been described frequently. Ventricular dilation affects 7% to 10% of patients with CM, but the ideal choice of surgical treatment is controversial. Wereport a case of a patient with Chiari malformation and hydrocephalus with improvement in clinical symptoms and ventricular dilatation. Case Description. A 19-year-old male complaining of frontal headache when coughing, laughing and during valsalva maneuvers, associated with dizziness for 2 months. Magnetic resonance (MR) showed hydrocephalus and small posterior fossa with overcrowding of contents, characterizing Chiari malformation type I, with cerebellar tonsils protruding through magnum foramen. Patient underwent surgery with posterior fossa decompression in a semi-sitting position and removal of the arc C1.After 3 months of follow-up, headache disappeared becoming asymptomatic. Control MR showed improvement of hydrocephalus with restoration of the cisterna magna and CSF flow. Discussion. Hydrocephalus has been related to CM for a long time. In our case, we performed treatment with intradural and intra-arachnoidal approach with bilateral tonsillectomy without placing ventricular shunt. The cisterna magna was “recreated”. There was improvement of hydrocephalus with decreased Evans ratio index and symptoms disappearance. Although there is no other studies addressing such matter, in this case, the improvement suggests that the CSF compression at the foramen magnum was the cause of associated hydrocephalus with Chiari malformation.

At the present time, the actual problem of dentistry is the study of the issues of the syndrome of pain dysfunction (SPD) of the temporomandibular joint (TMJ), which is found in 14-20% of teenagers and significantly increases with age (Siemkin V.A, Rabukhina N.A., 2000 ; Khavatova VA, 2005). The pathology of TMJ dysfunction was detected in 80% of the examined patients (Bezrukov V.M, 2002). Separately allocated dysfunction of TMJ in dysplastic-dependent form of joint pathology, thereby emphasizing that dysfunction is a characteristic manifestation of dysplasia of connective tissue in the maxillofacial area (Statovskaia Ye.Ye, 2005; Kozlov D.L., Viazmin A.Y., 2007). According to observations of A.I Mirza, I.V. Mikheieva, V.M. Novikov and according to our data, in more than 90% of people, pathological phenomena in the area of the temporomandibular joint have nothing to do with the inflammatory processes of this combination. At the same time, various dysfunctions and pain spasm of separate areas of chewing muscles occupy the main place. The aim of the work was to analyze the causes and clinical symptoms of patients with SPD. In this regard, as it turned out from the anamnesis, many patients had been undergoing inappropriate treatment for a long time. The cavity of the temporomandibular joint was repeatedly injected emulsion hydrocortisone acetate, antibiotics and other medications, which do not work in case of SPD of the temporomandibular joint. In some cases, after such therapy, dysfunction of the mandible occurred, leading to an even greater disruption of the joint function and increased pain. A number of patients with SPD of the temporomandibular joint due to a false diagnosis for a long time received treatment for neuralgia of the trigeminal nerve by drugs, Novocain blockade or alcoholization of sensitive branches of the trigeminal nerve. These patients often had neuritis, which greatly worsened the patient’s condition and the prognosis of the disease. The clinical picture of the SPD of the temporomandibular joint and a number of such diseases (syndromes of Slider, Sikara, etc.) is often so obscure and confusing that a large clinical experience is needed to evaluate individual symptoms. In addition, it should be noted that dysfunction of the mandible occurs with lesions of any part of the temporomandibular complex. Thus, limitation of the mobility of the mandible usually develops with arthritis of the temporomandibular joint, abscesses and phlegmons of the parotideomasseterica, temporal regions, pterygomandibulare, parapharingenal space, jaw-tongue groove and osteomyelitis of the branches of the mandible. Diagnostic difficulties often increase due to the fact that it is not always possible to find out the atypical etiological origin of the SPD of the temporomandibular joint. Against the background of the listed objective adverse factors, the presence of diagnostic errors largely contributes to insufficient knowledge of dentists who have clinical questions and questions on treatment of the SPD TMJ due to the difficulty in differential diagnosis, which is not fully covered in textbooks on dentistry. Control of correctness of the established diagnosis is the blockade of the motor branches of the trigeminal nerve subcutaneously using the Yehorov's method, which results in the removal of muscle spasm, stops pain and improves the mobility of the mandible. Conducting additional paraclinical examination methods such as dynamic MRT, 3-D MRT, CT and electromyography should be done.

Endometriosis is a chronic disease, influenced by internal and external environment, with long duration from intrauterine life with acme during childbearing, when it is associated to chronic pelvic pains, and infertility/subfertility. DNA hypermethylation of endometrial promoter PRs Hox genes and DNA hypomethylation of promoter ERβ gene is a possible explanation of estrogen dominance, progressive loss of progesterone signaling, followed by progesterone resistance in ectopic, and progesterone attenuance in eutopic endometrium, for failure of hormone therapy (HT), repeated recurrences after surgery, cancers after long time evolution. Animal models, human trials demonstrated progesterone (P4) and progestins influences over progression of disease pathological characteristics, associated to endometrial ER, PR aberrant expressions: ERα loss, and abnormal PRB/PRA ratio. P4 supplementation before mice induced-endometriosis protected from PRs depletion, action that can be translated in women according to the difference of 7 to 12 years between histologic onset and clinical symptoms/signs, parallel to progressive loss of PRs and PR-mediated signaling in ectopic and eutopic endometria. The animal studies have shown that a DNA methylation inhibitor alleviates lesion growth, and induces PRs target gene expression restoration. Continuous/extended contraceptives, dienogest- a new progestin, GnRH agonists/antagonists, aromatase inhibitors, SERM, SPRM, combinated molecules are therapeutic options/perspectives aiming restoration endometrial estrogen-progesterone balance, without disease’s cure. HT may be active alone, or surgery associated.

AbstractEffective screening of SARS-CoV-2 enables quick and efficient diagnosis of COVID-19 and can mitigate the burden on healthcare systems. Prediction models that combine several features to estimate the risk of infection have been developed in hopes of assisting medical staff worldwide in triaging patients when allocating limited healthcare resources. We established a machine learning approach that trained on records from 51,831 tested individuals (of whom 4,769 were confirmed COVID-19 cases) while the test set contained data from the following week (47,401 tested individuals of whom 3,624 were confirmed COVID-19 cases). Our model predicts COVID-19 test results with high accuracy using only 8 features: gender, whether the age is above 60, information about close contact with an infected individual, and 5 initial clinical symptoms. Overall, using nationwide data representing the general population, we developed a model that enables screening suspected COVID-19 patients according to simple features accessed by asking them basic questions. Our model can be used, among other considerations, to prioritize testing for COVID-19 when allocating limited testing resources.

Clinical descriptions of heart disease in children, congenital or acquired, are extremely rare prior to 1784 when Michael Underwood published his textbook on The Diseases of Children. In a chapter in his book Underwood summed up what had already been discovered about congenital heart disease and for the first time attempted to connect it with clinical symptoms. Dr. Robert Thaxter's case report of a child with a malformed heart is one of the earliest I have found in American medical journals. The subject of this case, a male, was at birth apparently well formed and healthy and remained very well 8 or 10 days. At this time he was attacked with the ordinary symptoms of cold which continued a long time very troublesome. He became very emaciated; which was attributed partly to the above cause, and partly to the mother, whose health was at this time bad. He remained in this emaciated state till he was about a year old at which time he began to grow corpulent and continued so till his death; though his extremities were small compared with his body and head. As soon as he began to move much, he was observed to breathe with difficulty, and his countenance to become livid. Rest generally restored him to a natural state. Cold, especially a cold wind, affected his respiration, sometimes almost producing suffocation, and rendered his surface very livid. Very hot weather had nearly as bad an affect as cold. Eating anything very hot produced the same effect.

A 40-year-old woman presented to our emergency department in an altered state following a generalised tonic-clonic seizure. On regaining consciousness, she gave a history of bleeding tendencies and menorrhagia, fatigue, nausea, vomiting and appetite loss for a long time. She had received multiple blood transfusions in the last 10 years. Investigations revealed severe hyponatraemia, transaminitis and pancytopenia, which showed cyclical fluctuations in the hospital. Hyponatraemia was attributed to a central cause owing to secondary hypothyroidism and hypocortisolism on evaluation. A diagnosis of cyclical thrombocytopenia was made by logging the trends of blood cell lines and applying the Lomb-Scargle test. Liver biopsy showed features of transfusion hemosiderosis explaining transaminitis. All of the haematological abnormalities and clinical symptoms resolved on thyroxine and corticosteroid replacement, suggesting causal association hypopituitarism with cyclical thrombocytopenia

Viruses of the honey bee have been known for a long time; however, recently the attention of scientists and apiculturalists has turned towards the relationship between these viruses and the parasitic miteVarroa jacobsoni. Although clinical symptoms indicated the presence of some of the viruses of bees in Hungary, none have previously been isolated or identified. During July unusual adult bee and brood mortality was observed in some colonies of an apiary in Budapest known to be infested withVarroa jacobsoni. Large amounts of acute paralysis virus (APV) were detected serologically in healthy honey bee pupae killed by the injection of a bacteria-free extract of diseased adult bees. Crystalline arrays of 30 nm particles were seen in ultrathin sections of the tissues of injected pupae and naturally infected adult bees. In spite of the application of acaricide treatments the bee population in several colonies had collapsed by the end of summer and the apiary suffered severe wintering losses.

Neuroendocrine tumors of the digestive system can cause very diverse clinical symptoms. Due to the secretion of biogenic amines, peptides and hormones secreted by the tumor cells, various paraneoplastic syndromes can evolve, on the other hand, the growth and spreading of hormonally inactive tumors can result in different local symptoms. Patients can be symptom-free for a long time or aspecific, often periodical symptoms can prevent recognition or lead to misdiagnosis for years. The symptomatology of hormonally active tumors, derived mainly from the pancreas is very characteristic. Carcinoid syndrome can be seen in 10-18% of patients with neuroendocrine tumors. In this review, the critical appreciation of laboratory and imaging modalities is discussed. Among the major new developments in this field, the introduction of serum chromogranin A assay and new small bowel examination methods should be mentioned. Capsule endoscopy and balloon enteroscopy can provide possibility of much more earlier diagnosis, as previously. The worldwide spreading of endoscopic ultrasound and fine needle biopsy allows the detection and clear localization of pancreatic neuroendocrine tumors. Orv. Hetil., 2011, 152, 371–378.

In 1986, after bovine spongiform encephalopathy (BSE) was discovered in the United Kingdom, over 183,000 cases have been confirmed to date. In 1996, the UK government announced that BSE may be transmitted to humans, causing variant Creutzfeldt-Jakob disease (vCJD). Retrospectively, the measures taken by the UK government were appropriate and the number of new cases of both BSE and vCJD decreased. Because of the long incubation period between infection and the appearance of clinical symptoms in both BSE and vCJD, a long time was needed to determine the effects of these measures. The inappropriate risk communication, however, caused people to lose trust in the UK government, and fear spread. In Japan, a cow infected with BSE was found in 2001. Although no cattle showing BSE symptoms were found and the risk of BSE infection was low, fear again spread due to inadequate risk communication. To allay consumer anxieties, the government began testing all cattle at slaughter facilities. This, in turn, generated the "blanket testing myth" - the misunderstanding that BSE testing was the most important measure needed to maintain the safety of beef consumption.

Understanding the pathomechanism of steatohepatitis (SH) is hampered by the difficulty of distinguishing between causes and consequences, by the broad spectrum of aetiologies that can produce the phenotype, and by the long time-span during which SH develops, often without clinical symptoms. We propose that SH develops in four phases with transitions: (i) priming lowers stress defence; (ii) triggering leads to acute damage; (iii) adaptation, possibly associated with cellular senescence, mitigates tissue damage, leads to the phenotype, and preserves liver function at a lower level; (iv) finally, senescence prevents neoplastic transformation but favours fibrosis (cirrhosis) and inflammation and further reduction in liver function. Escape from senescence eventually leads to hepatocellular carcinoma. This hypothesis for a pathomechanism of SH is supported by clinical and experimental observations. It allows organizing the various findings to uncover remaining gaps in our knowledge and, finally, to provide possible diagnostic and intervention strategies for each stage of SH development.
