Cytology is the diagnostic procedure of the microscopic evaluation of cells. It is becoming increasingly important and more frequently used in veterinary diagnostics, having many advantages including simplicity, speed and low cost. To determine the pathological changes diagnosed by cytology in cats, as well as the distribution of age, breed and gender in the diagnosed changes, we performed a retrospective study on slides submitted to the Department of Veterinary Pathology for routine cytological examination. The archive was searched for all feline cytology slides submitted from 2009 to 2018. All the slides were re-evaluated and classified into one of the four pathological processes: ‘neoplasia’, ‘inflammation’, ‘other condition’ or ‘non-diagnostic sample’. Breed, age, gender and the tissue from which the lesion was sampled were noted from the submission form, and statistically analyzed. The most frequent type of pathological process diagnosed was neoplasia, which reflects the high prevalence of neoplastic diseases in cats reported in literature data. Pathological changes were mostly diagnosed in domestic shorthaired cats of both sexes, with an average age of 8.4 years, but no breed, age or gender predisposition was found. The most evaluated tissue was skin, probably due to its accessibility and the ease of obtaining a sample from skin lesions. The most frequent neoplasia were malignant and the most frequent diagnosis was round cell neoplasia. Cats affected with round cell neoplasia had a significantly lower average age (7.3 years) than cats diagnosed with epithelial and mesenchymal neoplasia (9.9 and 10.3 years, respectively), probably reflecting the common retroviral infection in Croatian cats.

This study was conducted with the aim of evaluating the role of information and information resources in the awareness, control, and prevention of COVID-19. This study was a descriptive-analytical survey in which 450 participants were selected for the study. The data collection instrument was a researcher-made questionnaire. Descriptive and inferential statistics were used to analyze the data through SPSS. The findings show that a wide range of mass media has become well known as information resources for COVID-19. Other findings indicate a significant statistical difference in the rate of using information resources during COVID-19 based on age and gender; however, this difference is not significant regarding the reliability of information resources with regard to age and gender. Health information has an undisputable role in the prevention and control of pandemic diseases such as COVID-19. Providing accurate, reliable, and evidence-based information in a timely manner for the use of resources and information channels related to COVID-19 can be a fast and low-cost strategic approach in confronting this disease.

Background: Despite unclear pathogenesis, previous studies have suggested immune responses may play a pivotal role in the process of Moyamoya disease (MMD), a rare cerebrovascular occlusive disorder. The objective of this study is aimed to explore the change of peripheral Treg/Th17 in MMDpatients and whether the change is associated with pathogenesis of MMD. Methods: In the present study, we collected 26 MMD patients diagnosed by angiography according to the diagnostic criteria of definitive MMD and recruited 32 healthy volunteers. To explore the balance of peripheral Treg/Th17 in MMD patients, lymphocytes in peripheral blood were harvested and flow cytometry was used to measure the percentage of Treg and Th17in CD4+ Tcells, respectively. Meanwhile, relevant cytokines in serum were measured to evaluate the function of Treg and Th17 cells. Results: According to Suzuki’s angiographic staging of moyamoya disease, patients were divided into subgroups of the preliminary-term, medium-term and late-term. Cerebral hemorrhage is thefirstsymptom of onset occuringin half of patients, followed bycerebral ischemia.Our data revealed that both the percentage of Treg and Th17 cells in peripheral blood lymphocytes was increased in MMD patients compared with volunteer group. Meanwhile, the levels of IL-6, IL-10,IL-12, IL-17, TNF-α, VEGF and TGF-β in serum were significantly increased in MMD patients. In this study, the level of HMGB-1, a middle-late period inflammation biomarker, in serum of MMD patients is obviously elevated compared with volunteers. However, the ratio of Treg/Th17 had no significant difference in MMD patients compared to healthy volunteers. Intriguingly, our data revealed that ratio of Treg/Th17 was significantly increased in late-term MMD patients compared with medium-term patients as evidenced by elevated percentage of Treg cells.. In addition, TGF-β level in later-term MMD patients was significantly higher than this in medium-term MMD patients. No difference was observed in the way of onset and gender between two groups. Conclusion: Enhanced peripheral Treg and Th17 in MMD patients suggested that there may be an immunological component in the pathogenesis of MMD. Peripheral Treg may be associated with pathological process of MMD.

Background: Currently, there is an increase in the number of skin lesions of anogenital localization, which is a silent epidemic, both due to the steady increase in the incidence of this pathology, and the interdisciplinary aspect of this problem. Materials and methods: In the article, the authors first analyzed and presented the data of clinical and morphological analysis of 104 patients with various clinical variants of limited scleroderma, on the basis of which the main phenotypic and gender-specific clinical and topographical features of anogenital zone lesions in this group of patients are presented. Results: Scleroatrophic lichen is one of the clinical variants of limited scleroderma, which is characterized by damage to the mucous membranes of the external genitals in both women and men. Lesions of such localization are late and often mistakenly diagnosed by specialists of related disciplines (obstetricians, gynecologists, urologists, family doctors, allergists, cosmetologists), which leads to high risks of developing genitourenal syndrome. Conclusions: The development of scleroatrophic lesions in the anogenital zone is accompanied by pronounced clinical symptoms, including: itching, pain of varying intensity, dysuria, dyspareunia and significant sexual dysfunction.

Vein detection is an important issue for the medical field. There are some commercial devices for detecting veins using infrared radiation. However, most of these commercial solutions are cost-prohibitive. Recently, veins detection has attracted much attention from research teams. The main focus is on developing real-time systems with low-cost hardware. Systems developed to reduce costs suffer from low frame rates. This, in turn, makes these systems not suitable for real-world applications. On the other hand, systems that use powerful processors to produce high frame rates suffer from high costs and a lack of mobility. In this paper, a real-time vein mapping prototype using augmented reality is proposed. The proposed prototype provides a compromised solution to produce high frame rates with a low-cost system. It consists of a USB camera attached to an Android smartphone used for real-time detection. Infrared radiation is employed to differentiate the veins using 20 Infrared Light Emitting Diodes (LEDs). The captured frames are processed to enhance vein detection using light computational algorithms to improve real-time processing and increase frame rate. Finally, the enhanced view of veins appears on the smartphone screen. Portability and economic cost are taken into consideration while developing the proposed prototype. The proposed prototype is tested with people of different ages and gender, as well as using mobile devices of different specifications. The results show a high vein detection rate and a high frame rate compared to other existing systems.

Psoriasis is one of the most common chronic recurrent dermatoses, which is not limited to skin lesions, leading to a violation of the functions of various body organ systems. The article presents the results of the analysis of the medical histories of patients of Clinical dermatovenerologic dispensary (Krasnodar Region of Russia) with moderate-severe and severe forms of psoriasis and concomitant cardiological pathology. The article presents data from 70 case histories of patients with moderate to severe psoriasis, the analysis of which shows the clinical and practical significance of comorbidity of psoriasis. From the analysis, we conclude that there is a direct relationship between the severity of the course of the cutaneous pathological process and the aggravation of the cardiological diagnosis. The higher the severity of psoriasis, the higher the risk of developing acute coronary syndrome, myocardial infarction and other cardiac pathology.

Mast cell tumours (MCTs) are common in dogs and cats, but are only rarely reported in reptiles. This case documents the clinical and pathomorphological results from a Boa imperator with multiple cutaneous nodules, diagnosed as MCT based on histopathology, immunohistochemistry and electron microscopy approaches. Grossly, there were multifocal, poorly demarcated, mostly ulcerated nodules ~3 cm in diameter on the skin. Histologically, the dermis and the subcutaneous tissue were infiltrated by round cell populations with eosinophilic granules. Toluidine blue and Giemsa stain revealed metachromatic granules. Using immunohistochemistry, some cells exhibited cytoplasmic immunostaining positive for tryptase. Ultrastructurally, variable quantities of intracytoplasmic, spherical and electron-dense granules were also detected. The MCT literature on snakes is scarce, especially for the family Boidae, but MCTs should be considered a differential diagnosis for nodular skin lesions in reptiles.

PURPOSE: Most primary cutaneous B-cell lymphomas have an excellent prognosis. However, primary cutaneous large B-cell lymphomas (PCLBCLs) of the leg have been recognized as a distinct entity with a poorer prognosis in the European Organization for Research and Treatment of Cancer (EORTC) classification. This distinction on the basis of site has been debated. Our aim was to identify independent prognostic factors in a large European multicenter series of PCLBCL.PATIENTS AND METHODS: The clinical and histologic data of 145 patients with PCLBCL were evaluated. According to the EORTC classification, 48 patients had a PCLBCL of the leg and 97 had a primary cutaneous follicle center-cell lymphoma (PCFCCL). Data from both groups were compared. Univariate and multivariate analyses of specific survival were performed using a Cox proportional hazards model.RESULTS: Compared with PCFCCL, PCLBCL-leg were characterized by an older age of onset, a more recent history of skin lesions, a more frequent predominance of tumor cells with round nuclei and positive bcl-2 staining, and a poorer 5-year disease-specific survival rate (52% v 94%; P < .0001). Univariate survival analysis in the entire study group showed that older age, a more recent onset of skin lesions, the location on the leg, multiple skin lesions, and the round-cell morphology were significantly related to death. In multivariate analysis, the round-cell morphology (P < .0001), the location on the leg (P = .002), and multiple skin lesions (P = .01) remained independent prognostic factors. The round-cell morphology was an adverse prognostic factor both in PCLBCL-leg and in PCFCCL, whereas multiple skin lesions were associated with a poor prognosis only in patients with PCLBCL-leg.CONCLUSION: With site, morphology, and number of tumors taken into account, guidelines for the management of PCLBCL are presented.

This article contains rather motivating than teaching information. It is a synthesis of analysis of authoritative global scientific publications and personal experience. The modern approaches to diagnosis of critical respiratory incidents using ultrasound, superficial theoretical review of the core of the method and our own experiences regarding effective protocol of sonographic lung assessment are presented here. Several interesting clinical cases emphasize the advantages of routine use of diagnostic ultrasound in patients with critical uncompensated respiratory disaster as well as in sub-compensated and compensated patients. The main principles of bedside lung ultrasound in emergency that should encourage wider implementation and use of this method by doctors of different specialties are: “Lung ultrasound is very easy to perform using simple equipment”, and “BLUE-protocol is a simple protocol that allows quick (< 3 min) diagnosis of the cause of respiratory failure”. Lung sonographic assessment allows not only to determine quickly the cause of critical respiratory failure and counteract it starting the etiotropic treatment as soon as possible, but also visualize the dynamics of pathological changes in response to therapy, thus allowing us to evaluate its effectiveness properly. The use of ultrasound in diagnosing enables more adequate decision making regarding the need of interventional therapy. It also leads to setting the right diagnosis faster, improving the quality of medical care, shortening the length of stay of patients in ICU, decreasing the total cost of the treatment. Identification and analysis of the amount of sonographic signs “B-lines – lung rockets” provides an opportunity to measure the volume/amount of interstitial lung fluid properly and track this marker/indicator in dynamics in response to the treatment. The unified method of protocolized assessment should be used within one medical facility in order to boost effectiveness and make evaluation and dynamic evaluation of pathological changes more objective by the same one or different medical specialists. Diagnostic ultrasound has a very low cost and there is no radiation exposure to patients which allows performing as many examinations as needed, without limitations.

Background: Sporotrichosis is caused by pathogenic fungi of the genus Sporothrix. The clinically relevant species are S. schenckii, S. globosa and S. brasiliensis. In Brazil, S. brasiliensis is the most prevalent etiological agent among humans and cats. In cats with sporotrichosis, skin lesions are mainly characterized by nodules and ulcers, usually located in the head, nasal region and limbs. The presence of respiratory signs concomitantly with cutaneous lesions is frequent, especially sneezing, and may be associated with lesions located in the nasal mucosa. Ketoconazole (KTZ), itraconazole (ITZ), potassium iodide (KI), sodium iodide (NaI), terbinafine (TRB), fluconazole (FLZ) and amphotericin B (AMB) are the drugs currently available for treating feline sporotrichosis. ITZ remains the drug of choice. ITZ combined with KI has been successfully used in the treatment of naïve cats (especially cases with lesions in the nasal region), cases of recurrence and refractory to ITZ. Clinical cure with NaI has been described in some cases, but its use has been limited by adverse reactions. The conventional formulation is the saturated solution and the recommended dose in the treatment of feline sporotrichosis is 10 mg/kg every 12 h. Cats are sensitive to iodide preparations and should be carefully monitored for clinical evidence of iodism, such as apathy, anorexia, vomiting, diarrhea, hypothermia, hyperthermia, cardiomyopathy, hyperexcitability, muscular spasms and ptyalism. The purpose of this study was to evaluate the therapeutic response of NaI capsules in feline sporotrichosis.Materials, Methods & Results: An observational cohort study was conducted in cats with sporotrichosis at the Laboratory of Clinical Research in Dermatozoonoses in Domestic Animals (Lapclin-Dermzoo), Evandro Chagas National Institute of Infectious Diseases (INI)/Oswaldo Cruz Foundation (Fiocruz), Rio de Janeiro, Brazil. Twenty-eight cats with sporotrichosis confirmed by isolation of Sporothrix spp. in culture, no previous systemic antifungal therapy, and weight above 3.0 kg, were included in the study. The treatment consisted of NaI oral capsules (5 mg/kg/once daily). In cats without clinical improvement after one month of treatment, the dose was increased (10 mg/kg/once daily). The cats were followed up monthly by clinical examination, complete blood count and biochemical analysis (urea, creatinine, alanine aminotransferase - ALT, aspartate aminotransferase - AST, alkaline phosphatase - FA). All procedures were approved by the Animal Ethics Committee (CEUA/Fiocruz), number LW 56/13, and the informed consent term was obtained from all tutors. Clinical cure was achieved in six (21.4%) cases and treatment failure was observed in 13 (46.4%) animals. Seven (25%) cats were lost during follow up, and unknown causes of death occurred in two cases (7.1%). Ten animals (35.7%) presented clinical adverse reactions at some point during treatment. Hyporexia and weight loss were the most frequent ones. Three cats presented alteration in renal function.Discussion: Treatment of feline sporotrichosis in epizootic areas has been a challenge for veterinarians and tutors. Additionally, there are few studies evaluating treatment regimens for this mycosis in animals. In this study, NaI was compounded in capsules, because it is easier to administer when compared to the solution, as previously described for KI. Despite the low cost and the convenient administration of the capsule, NaI presented a low cure rate with the dose used. The study of new pharmaceutical forms and lower doses of low-cost drugs is necessary in a scenario of epizootic sporotrichosis, where investments for the development of new antifungal agents are scarce.

Early in the SARS-CoV-2 pandemic, many national public health authorities implemented non-pharmaceutical interventions to mitigate disease outbreaks. Panamá established mandatory mask use two months after its first documented case. Initial compliance was high, but diverse masks were used in public areas. We studied behavioral dynamics of mask use through the first two COVID-19 waves in Panama, to improve the implementation of effective, low-cost public health containment measures when populations are exposed to novel air-borne pathogens. Mask use behavior was recorded from pedestrians in four Panamanian populations (August to December 2020). We recorded facial coverings and if used, the type of mask, and gender and estimated age of the wearer. Our results showed that people were highly compliant (>95%) with mask mandates and demonstrated important population-level behaviors: (1) decreasing use of cloth masks over time, and increasing use of surgical masks; (2) mask use was 3-fold lower in suburban neighborhoods than other public areas and (3) young people were least likely to wear masks. Results help focus on highly effective, low-cost, public health interventions for managing and controlling a pandemic. Considerations of behavioral preferences for different masks, relative to pricing and availability, are essential for optimizing public health policies. Policies to increase the availability of effective masks, and behavioral nudges to increase acceptance, and to facilitate mask usage, during the ongoing SARS-CoV-2 pandemic, and for future pandemics of respiratory pathogens, are key tools, especially for nations lagging in access to expensive vaccines and pharmacological approaches.
