Background.Liver diseases associated with pregnancy are recorded in 0.73% of pregnant women, often accompanied by the development of hepatic dysfunction/insufficiency, and are the cause of increased morbidity and mortality in both mother and child. A pathomorphological study helps to understand the pathophysiology of severe liver damage in preeclampsia, and to optimize the management of such patients.Aims to study the clinical, morphological and immunohistochemical features of liver tissue lesions in the most severe forms of preeclampsia and eclampsia, which ended in death.Methods.Autopsy material analysis of 10 patients who died from preeclampsia, eclampsia and their complications (main group) and 3 patients who died from other causes (comparison group). Pathomorphological and immunohistochemical studies of organs and tissues (in particular, liver tissue) were performed using a marker of neurons and neuroendocrine cells -NSE and a marker of endotheliocytes CD-34.Results.An immunohistochemical study with a CD-34 endotheliocyte marker in the main group revealed a vascularization deficiency in the 2nd and 3rd zone of hepatic acini, there were also foci of necrosis. Such changes indicate deep and prolonged hypoperfusion. The use of the NSE marker in the group of patients who died from preeclampsia/eclampsia revealed a sharp increase in Kupffer cells in the first and second zones of acini with pronounced immunoexpression of NSE in the nuclei and cytoplasm of these cells, which indicates severe hepatic dysfunction (in particular, impaired detoxification and elimination functions of the liver). At the same time, only 3 out of 10 women in the main group are clinically registered with HELLP syndrome, while the rest had signs of multiple organ (including acute liver) failure.Conclusions.The clinical symptoms of liver damage, including those with severe preeclampsia, arise, as a rule, already against the background of severe morphological changes in its tissue and, as a rule, indicate functional decompensation. Liver immunology remains little studied, which requires further research on this problem.

In this study examined the effects of a multivalent protease inhibitor aprotininum on the state indicators of blood coagulation and antiproteinase potential during the development of experimental reperfusion syndrome, as well as the severity of morphological changes in liver tissue. It was found that with a 12-hour reperfusion syndrome in the background the development of an imbalance in the proteinase-inhibitor system occurs coagulopathy consumption and there are initial liver damage with development necrosis and plethora of blood vessels. Against the background of the use of aprotininum with experimental reperfusion syndrome is less marked severe liver damage decreases imbalance in condition of non-specific proteinases and their inhibitors without deeper disorders in the blood coagulation system.

A total of 62 patients engaged in antibiotic production (main group) and 59 control subjects were examined. Risk factors of ulcer disease in these patients could be dust inhalation, contact with solvents, shift work, and smoking. Patients of the main group had a more severe disease and higher frequency of complications, larger amounts of Helicobacter pylori in the gastric mucosa, its more pronounced morphological changes, slower disappearance of clinical symptoms of exacerbation, and longer period of ulcer scarring. Also, they underwent more severe disorders of humoral immunity than control subjects which might account for the unfavourable clinical picture of their condition.

Possible Cause

Background Hepatic and neurologic injury developed in two infants after ingestion of mint tea. Examination of the mint plants, from which the teas were brewed, indicated that they contained the toxic agent pennyroyal oil. Methods. Sera from each infant were analyzed for the toxic constituents of pennyroyal oil, including pulegone and its metabolite menthofuran. Results. Fulminant liver failure with cerebral edema and necrosis developed in the first infant, who died. This infant was positive only for menthofuran (10 ng/mL). In the other infant, who was positive for both pulegone (25 ng/mL) and menthofuran (41 ng/mL), hepatic dysfunction and a severe epileptic encephalopathy developed. Conclusions. Pennyroyal oil is a highly toxic agent that may cause both hepatic and neurologic injury if ingested. A potential source of pennyroyal oil is certain mint teas mistakenly used as home remedies to treat minor ailments and colic in infants. Physicians should consider pennyroyal oil poisoning as a possible cause of hepatic and neurologic injury in infants, particularly if the infants may have been given home-brewed mint teas.

In October 1909, the speaker met at an autopsy a completely peculiar liver damage in a 21-year-old child, more than 3 years of diarrhea and a significant increase in the spleen (with ascites); the last one was removed to him, and the patient died from septic peritonitis. The liver was smooth, 1270 gm. vѣsom and extremely soft; in the portal vein and she herself turned out to be clogged with blood clots, red in the liver, and whitish in the drink itself. Liver tissue appeared to be red and och. soft, in some places whitish-yellowish color; areas of the last days formed nodes in the forms of cerebral convolutions, enveloping the rays of the Glisson capsule with large veins; the convolutions seemed striated, as if folded from the tubes, vertical to the axis of the crossbeam of the Glisson capsule. Such whitish areas were scattered everywhere and in the red parenchyma, not sharply delimited * from it and without lobular structure.

Potential Biomarker

Preeclampsia is the major cause of maternal and fetal deaths worldwide. Circulating biomarker concentrations to predict preeclampsia must be determined. Therefore, the objective was to evaluate heme oxygenase-1 (HO-1) concentration in both plasma and urine samples from pregnant women before the development of preeclampsia and to identify a potential biomarker for preeclampsia development. We performed a case-control study nested in a prospective study cohort at University Hospital of the Ribeirao Preto Medical School, University of São Paulo (HCFMRP-USP), Ribeirao Preto, Brazil. Of 1400 pregnant women evaluated at 20–25 weeks of gestation, 460 delivered in hospitals outside our institution. Of 940 pregnant women who completed the protocol, 30 developed preeclampsia (cases, 14 cases of severe preeclampsia and 16 cases of mild preeclampsia). Healthy pregnant women (controls, n=90) were randomly selected from the remaining 910 participants. HO-1 concentration was evaluated in plasma/urine samples by using a commercial enzyme-linked immunosorbent assay kit. We found similar HO-1 levels in the plasma and urine for case and control groups. In the subgrouped preeclampsia, lower plasma HO-1 levels were found in mild compared with severe preeclampsia. We conclude that plasma HO-1 levels were not altered at 20–25 weeks of gestation before the manifestation of preeclampsia symptoms. Pregnant women who subsequently develop severe preeclampsia show higher expression of HO-1. This may be indicative of important underlying pathophysiologic mechanisms that differentiate between mild and severe preeclampsia and may possibly be related to a higher prooxidative status even before the development of clinical symptoms.

Aim. To assess the effectiveness of the use of the antiviral drug enisamium iodide in the complex treatment of acute respiratory viral infections (ARVI) caused by various pathogens in routine clinical practice. Materials and methods. А prospective randomized study included 134 patients who were treated in the epidemic season of influenza and ARVI in 20182019. All patients were examined for the presence of influenza A and B viruses, respiratory syncytial virus, human metapneumovirus, parainfluenza virus, coronaviruses, rhinoviruses, adenoviruses in nasopharyngeal swabs by PCR. Patients of the main group received enisamium iodide along with symptomatic therapy, the control group received only symptomatic therapy. The primary parameter of the effectiveness of therapy was evaluated on the scale of the general severity of the manifestations of ARVI (Total Symptom Score TSS) from the 2nd to the 4th day and by the secondary criteria of effectiveness: assessment of the duration of ARVI, the severity of fever, the proportion of patients with normal body temperature, the duration of the main clinical symptoms of acute respiratory viral infections, the proportion of patients in whom complications requiring antibiotics were noted, the dynamics of interferon status on the 6th day. To conduct a statistical analysis, depending on the efficiency parameter, the ANCOVA method with a fixed group factor and an initial score on the TSS severity scale was used as covariates, a criterion for comparing quantitative indicators in two independent groups. Results. According to the results of the analysis of the primary efficacy parameter, the median (interquartile range) of the average score on the scale of the general severity of ARVI manifestations in the main group was 4.33 (3.675.83), in the comparison group 6.00 (4.677.25; p0.001). The duration of systemic and local manifestations of acute respiratory viral infections was statistically significantly less in the main group (p=0.002 and p=0.019, respectively). Prescription of additional therapy was required in 2 (2.9%) patients of the main group (patients taking enisamium iodide), compared with 8 (11.9%) patients in the control group. Serum levels of interferon  and interferon  on the last day of treatment were statistically significantly higher in patients of the main group compared with the control group (p0.001). Treatment (excellent) was evaluated by 42 (62.7%) patients, while in the control group only 17 (25.8%) patients gave similar ratings. Both patients (p0.001) and doctors (p0.002) rated therapy tolerance better in the study group. Conclusion. The results confirmed the safety and effectiveness of enisamium iodide as a treatment for ARVI and influenza. The antiviral, interferonogenic and anti-inflammatory properties of the drug are involved in the formation of an antiviral response and reduce the risk of complications, which makes it possible to reduce the number of symptomatic agents used.

COVID-19 manifests itself in a wide spectrum of clinical symptoms, both in terms of their variety and severity. It can be asymptomatic or abortive, mild, moderate, severe and lightning, as septic with multiple organ failure and shock Typical leading symptoms of COVID-19 are: high fever poorly responding to drugs, severe loss of strength, chest pain, dyspnoea, pain headaches, bone and joint pain and muscle pain, until the onset of acute respiratory distress syndrome (ARDS). However, many publications mention among the possible symptoms also others, not related to the involvement of the lower respiratory tract. These are gastrointestinal disorders, damage to the central and peripheral nervous system, catarrh of the upper respiratory tract and dysfunctions of the sensory organs. The aim of this literature review was to determine the frequency of various head and neck dysfunctions that are part of COVID-19. Symptoms of conjunctivitis, nasal mucosa, pharynx and larynx are reported by about of patients, but they do not always occur at the same time, as in infections caused, for example, by rhinoviruses. Anosmi / hyposmia or ageusia / hypogeusia occur with a similar frequency. Symptoms of damage to the equilibrium system, such as dizziness, are reported by approx. 1/3, vertigo and hearing loss approx. 5-6%, tinnitus approx. 10% of patients. Reports of coexistence with COVID-19 of peripheral paresis of the facial nerve are so far relatively few and often included in the neurological disorders, the frequency of which is also about 1/3 of COVID-19 cases. Importantly, both catarrhal symptoms and the others listed here may precede, co-occur or follow the appearance of the leading symptoms of COVID-19. They can also be the only symptoms of this disease. This should prompt otorhinolaryngologists to be particularly vigilant in this regard
