Carcinoma Of Gallbladder

Generally, carcinoma of the gallbladder is an extremely unusual neoplasm, however, high incidence rates have been reported in certain parts of the world. The role of certain factors such as genetic susceptibility, lifestyle and infections of gallbladder in causing carcinogenesis is still not clearly understood. Due to its early vague symptoms and lack of serosa in the gallbladder to slow its spread, gallbladder carcinoma typically presents at an advanced stage with a five-year survival rate of less than 5%. Pseudopancreatic cyst is an uncommon but not a rare complication of acute pancreatitis and injury to the pancreas. However, it rarely presents with carcinoma of gallbladder. We present here an unusual case of gallbladder carcinoma with pseudopancreatic cyst in a 58-year old male.

The Impact

Uveal melanoma (UM) is currently classified by the World Health Organisation as a melanoma caused by risk factors other than cumulative solar damage. However, factors relating to ultraviolet radiation (UVR) susceptibility such as light-coloured skin and eyes, propensity to burn, and proximity to the equator, frequently correlate with higher risk of UM. These risk factors echo those of the far more common cutaneous melanoma (CM), which is widely accepted to be caused by excessive UVR exposure, suggesting a role of UVR in the development and progression of a proportion of UM. Indeed, this could mean that countries, such as Australia, with high UVR exposure and the highest incidences of CM would represent a similarly high incidence of UM if UVR exposure is truly involved. Most cases of UM lack the typical genetic mutations that are related to UVR damage, although recent evidence in a small minority of cases has shown otherwise. This review therefore reassesses statistical, environmental, anatomical, and physiological evidence for and against the role of UVR in the aetiology of UM.

Abstract Background Gallbladder carcinoma is often found incidentally on histopathologic examination after cholecystectomy—this is referred as incidental gallbladder carcinoma (IGC). Routine vs selective histopathological assessment of gallbladders is under debate and this study evaluates the role of regular specimens’ examination, based on a single-centre analysis of incidence, clinical and histopathological aspects of IGC. Methods Patients who underwent cholecystectomy, between July 2010 and January 2020, were considered. Exclusion criteria were age under 18 and preoperative diagnosis of GB carcinoma. Demographic, clinical and histopathological data were retrospectively collected, continuous variables with a normal distribution were evaluated with Student’s t-test and ANOVA. Results Some 5779 patients were included. The female/male ratio was 2.5:1. Chronic cholecystitis (CC) was the most common finding on specimens (99.3%), IGC was found in six cases (0.1%). In the latter group, there were 5 women and patients were older than those with benign disease—73.7 $$\pm$$ ±  5.38 years vs 55.8 $$\pm$$ ±  0.79 years (p < 0.05). In all the cases, the GB was abnormal on intraoperative inspection and beside cancer, histopathology showed associated CC and/or dysplasia. Upon diagnosis, disease was at advanced stage—one stage II, one stage IIIA, one stage IIIB, three stage IVA. Two patients are alive, three died of disease progression—median survival was 7 months (range 2–14). Conclusions In this series, ICG was rare, occurred most commonly in old adult women and was diagnosed at an advanced stage. In all the cases, the GB was abnormal intraoperatively, therefore macroscopic GB anomalies demand histopathological assessment of the specimen.

Abstract Background : Diarrheal infections remain relevant for many countries of the world. The processes of globalization, fundamental changes in nutrition and water consumption contributed to the fact that the significance of individual infection sources, etiological structure of diarrheal infections changed. Purpose of the study: on the background of the analytical study of the incidence of diarrheal infections in Ukraine under the current conditions, to determine the factors influencing epidemic situation. Methods: The reports of the Ministry of Health of Ukraine, Main Administrations of Statistics in Kharkiv, Odesa, Zaporizhia oblasts for 2011-2018 are used in the paper. Epidemiological and statistical research methods are applied. Results: The epidemic situation with diarrheal infections in Ukraine is characterized by a low incidence of typhoid fever (from 0.012 to 0.14 per 100 thousand people), shigellosis (from 1.97-6.13 per 100 thousand people), stable incidence rates without the downward trend, salmonellosis (from 17.35 till 24.1 per 100 thousand people), high incidence of diahrreal infections of specified etiology (from 115.5 to141.9 per 100 thousand people) and diahrreal infections of unspecified etiology (from 69.76 to 107.02 per 100 thousand people). The most complicated epidemic situation is observed in economically most developed regions of the country. Most diarrheal infectionsoutbreaks are connected with catering establishments 36.5 % and with children educational establishments 26.1 %. In the region with the highest shigellosis and salmonellosis incidence direct strong correlation relationships are established between the incidence and population, density, natural population movement. The oblasts with the highest diahrreal infections of specified etiology, rotaviral enteritis, diahrreal infections of unspecified etiology incidence are at least provided with water resources and have problems with provision of high-quality drinking water. There is a need to improve the system of epidemiological surveillance over diarrheal infections by extension of the indicators of microbiological study of drinking water quality in the regions of Ukraine, where high diahrreal infections of specified etiology, rotaviral enteritis, diahrreal infections of unspecified etiology incidence is registered; by increasing frequency of food item inspections in the oblasts, where mediana shigellosis and salmonellosis incidence exceeds the average one in Ukraine. Keywords: diarrheal infections, shigellosis, salmonellosis, rotaviral enteritis.

Coronavirus Infection

The central nervous system seems to be quite vulnerable to SARS-CoV-2, leading to a variety of alteration pathways, high incidence and variability of the neurological symptoms of COVID-19. The COVID-19 symptoms, possibly associated with alteration to the central nervous system, include hyperthermia, shortness of breath, fatigue, headache, dizziness, dysphonia, dysphagia, hyposmia and anosmia, hypogeusia and ageusia, impairment of consciousness. The impairment of olfaction and gustation are the most common symptoms of the nervous system alteration (98% and 70%, respectively), which is most likely a consequence of the alteration of the receptors. Presumably the pathogenesis of dysphonia and dysphagia may involve neurodegenerative mechanisms or may be associated with a predominantly demyelinating alteration of the caudal cranial nerves. Pathomorphological findings in the brain of the COVID-19 patients include diffuse hypoxic and focal ischemic injuries of various sizes up to ischemic infarctions (in thrombosis of large arteries); microangiopathy; vasculitis; diapedetic and confluent hemorrhages with possible progression to hemorrhagic infarctions and rarely intracerebral hematomas. Acute cerebrovascular accident worsens the course of COVID-19 and can worsen the clinical outcome, taking into account the mechanisms of the central nervous system alteration in highly contagious coronavirus infections (SARS-CoV, MERS, SARS-CoV-2), including embolism, hypoxia, neurodegeneration, systemic inflammatory response and immune-mediated alteartion to the nervous tissue. A fairly rare complication of coronavirus infection, however, acute myelitis requires attention due to the severity of neurological disorders. The literature data show high incidence and polymorphism of the symptoms of the central nervous system alteration, as well as the important role of the cerebrovascular and neurodegenerative pathogenesis of brain alteration in COVID-19, which is taken into account in examining and treating the patients with new coronavirus infection.

AbstractThe role of language and linguistic-philological studies in the nationalist movements of the nineteenth century received much attention. The aim of this article is to focus on the language factor in Zionism and the revival of Hebrew as a spoken language in the Yishuv between 1904 and 1914. Founded in 1904, the Hebrew Language Council was expected to enhance the process of revival and, from the very beginning, an unmistakably nationalist attitude to its subject matter marked the Council's agenda. However, the authority of the Council to make binding decisions on linguistic matters was contested by a number of other Zionist institutions, a development which ruined the prestige and effectiveness of the Council. The controversy resulted less from a turf war or quarrels over scarce resources than a deeper question of which institution represented the “true” Hebraic spirit. The World Zionist Organization's decision to de-align from cultural matters, including the revival of Hebrew, worsened the conditions under which the Council operated. From a comparative perspective, thus, the Hebrew case provides an unusual case of linguistic nationalism, which should be of interest to students of both nationalism and sociolinguistics.

Primary paraganglioma of the external auditory canal is a rare otological finding. To date, only three cases have been reported in the world-wide literature. Such a tumour is now described in a 42-year-old female. The clinical and histopathological features of the case are discussed. The role of immunocytochemistry in defining diagnosis, from a large list of differentials, is illustrated. We present the first magnetic resonance images of this rare tumour and highlight the benefit of intra-operative frozen section in limiting surgery to canal excision.

The Impact

SARS-CoV-2 has now infected 15 million people and produced more than six hundred thousand deaths around the world. Due to high transmission levels, many governments implemented social-distancing measures and confinement with different levels of required compliance to mitigate the COVID-19 epidemic. In several countries, these measures were effective, and it was possible to flatten the epidemic curve and control it. In others, this objective was not or has not been achieved. In far to many cities around the world rebounds of the epidemic are occurring or, in others, plateau-like states have appeared where high incidence rates remain constant for relatively long periods of time. Nonetheless, faced with the challenge of urgent social need to reactivate their economies, many countries have decided to lift mitigation measures at times of high incidence. In this paper, we use a mathematical model to characterize the impact of short duration transmission events within the confinement period previous but close to the epidemic peak. The model describes too, the possible consequences on the disease dynamics after mitigation measures are lifted. We use Mexico City as a case study. The results show that events of high mobility may produce either a later higher peak, a long plateau with relatively constant but high incidence or the same peak as in the original baseline epidemic curve, but with a post-peak interval of slower decay. Finally, we also show the importance of carefully timing the lifting of mitigation measures. If this occurs during a period of high incidence, then the disease transmission will rapidly increase, unless the effective contact rate keeps decreasing, which will be very difficult to achieve once the population is released.
