A 7 yr old Labrador retriever initially presented for severe halitosis, mild ptylism, and depigmentation of the nasal planum. Erythema multiforme was diagnosed based on clinical signs and dermatopathology. Treatment was initiated but the condition did not resolve. Six months later, the dog was diagnosed with a mediastinal mass. Trucut biopsy was performed and histopathologic diagnosis was consistent with a thymoma. A median sternotomy was performed, the thymoma was excised, and the dog recovered well. Four months postoperatively, there were no longer any obvious erythema multiforme lesions and the skin condition was controlled without medication. Erythema multiforme may be a paraneoplastic disorder associated with thymoma in the dog, similar to thymoma-associated exfoliative dermatitis in the cat. Clinical signs of erythema multiforme may warrant performing thoracic radiographs or thoracic CT to rule out thymoma as an underlying cause.

Canine distemper is a multisystemic contagious viral disease having a worldwide distribution, a high mortality rate, and significant central neurologic system (CNS) complications. In its systemic manifestations, it is often presumptively diagnosed on the basis of clinical signs and history. Few definitive antemortem diagnostic tests exist, and most are limited to the detection of viral antigen by immunofluorescence techniques on tissues or cytologic specimens or high immunoglobulin levels in CSF (cerebrospinal fluid). Diagnosis of CNS distemper is often unreliable due to the relatively low cell count in CSF (<50 cells/μl) and the binding of blocking immunoglobulins in CSF to cell surfaces. A more reliable and definitive test might be possible utilizing direct morphologic detection of the etiologic agent. Distemper is the canine equivalent of human measles, in that both involve a closely related member of the Paramyxoviridae, both produce mucosal inflammation, and may produce CNS complications. In humans, diagnosis of measles-induced subacute sclerosing panencephalitis is through negative stain identification of whole or incomplete viral particles in patient CSF.

SummaryFeline cutaneous paraneoplastic syndrome is a rare disorder associated mainly with pancreatic carcinoma and thymoma. In this report the authors describe the case of a 12-year-old cat with paraneoplastic exfoliative dermatitis associated with thymoma. Lateral radiographic examination of the chest showed a small subtle soft tissue density in the ventral part of the first and second intercostal space, which together with skin changes suggested thymoma. Because of pain associated with the skin condition, costs of treatment and the risk associated with surgical treatment, the owner chose euthanasia of the cat. Post-mortem examination revealed a tumour which was diagnosed as thymoma by histopathological examination.

Objective: Erythema Multiforme (EM) is an acute mucocutaneous hypersensitivity reaction triggered by certain infections and medications. EM induced by virus infection termed as Herpes- associated Erythema Multiforme (HAEM). The use of corticosteroids for treating HAEM has been a long debate issue. The aim of this case report is to present a patient with HAEM who was successfully treated with acyclovir combined with prednisone.Methods:A 31-years-old female, presented with a complaint of pain and diffuse ulcers in mouth. The patient reported recurrent episode of the ulcers of the mouth during the last two years. On extra oral examination, lips were crusted and bleeding. Intraoral examination revealed multiple diffuse ulcerations on mucosa. Nolesions were seen in other part of the body. Laboratory investigation revealed normal complete blood count and positive HSV-1 serology. The patient was diagnosed as HAEM.The patient was treated with acyclovir (1000 mg/day) and prednisone (10mg/day), topical mixture corticosteroid, chlorhexidine gluconate 0.2% and multivitaminduring seven days.Results:All lesions healed without any further clinical sequelae within 7 days.The clinical success of corticosteroids as effective anti-inflammatory agents is largely attributed to their ability to reduce the expression of pro-inflammatory genes, help to maintain vascular integrity and decrease the expression of leukocyte adhesion molecules.Conclusions:The addition of prednisone to acyclovir for HAEM resulted in a significant reduction of clinical signs and symptoms during the first week. The combination of acyclovir and corticosteroids may play an important role in the standard care for HAEM.

The aim of this study was to evaluate the suitability of fermented oat (FO) and black soldier fly larva (BSFL) as food ingredients for dogs. A total of 20 spayed female dogs were divided into four treatment groups, with 5 dogs per group. The four treatment groups consisted of a control group, a diet with 10% FO, one with 5% BSFL, and one with 10% FO and 5% BSFL, and each experimental food was fed for 12 weeks. The feeding of FO and/or BSFL did not affect the daily food intake, body weight, body condition score, fecal score, or skin condition of the dogs. In all the experimental groups, no significant differences in serum IgG, IL-10, or TNF-α levels were observed upon the feeding of FO and/or BSFL. Some hematological (white blood cell and basophils) and serum biochemical parameters (phosphorous, globulin, and alkaline phosphatase) showed significant differences with FO and/or BSFL feeding compared to the control group, but they were within the normal reference range. No adverse clinical signs related to these parameters being affected by FO and BSFL were observed. The feeding of BSFL for 12 weeks reduced the serum cholesterol level (p < 0.05) at the end of the experiment. Our findings suggest the suitability of FO and BSFL as food materials for dogs.

The development of an effective and safe drug for the treatment of patients with COVID-19 is currently an urgent task for the global medical community. Given that lung damage remains the predominant syndrome in COVID-19, and the development of acute respiratory distress syndrome (ARDS) is the most common reason for transfer to intensive care unit and connection to artificial lung ventilation, it seems promising to study the effectiveness and safety of surfactant therapy, successfully proven in practice in the treatment of adult and preterm infants ARDS. Despite the fact that most studies are devoted to the use of this method in patients in the acute stage, we present a case from our own practice of Surfactant-BL inhalation in a patient with COVID-19-associated pneumonia at the 2nd stage of rehabilitation treatment. Clinical signs of respiratory failure (RR 22 per minute, Sa O2 86% on atmospheric air, 95% on insufflation of humidified oxygen 7 L/min), high percentage of lung tissue damage according to thoracic CT (55% – CT3) on admission to the Medical Rehabilitation Unit, as well as a score of 6 on the NEWS2 scale served as a basis for the patient to receive Surfactant-BL inhalation for the indication «prevention of the development of acute respiratory distress syndrome» in a dosage of 75 mg twice a day for 5 days. Positive dynamics of clinical data at the end of the course of inhalations (decrease of RR to 16 per minute, increase of Sa O2 to 90% on atmospheric air and to 95% on insufflation of humidified oxygen 5 l/min, improvement of auscultatory picture), as well as the control thoracic CT scan, which showed a decrease of lung parenchyma damage to 45.2% (CT-2), indicated the effectiveness and safety of this method in the complex rehabilitation of COVID-19 patient, being a basis for further investigation of this issue

Background. Pelvic inflammatory diseases (PID) occur in 12-13 % of young women, 65-70 % of outpatients and 30 % of inpatients with gynecological diseases. The consequences of PID include infertility, chronic pelvic pain syndrome, menstrual disorders, etc. Treatment of PID is a multidisciplinary problem in the field of gynecology, urology, and venereology. Objective. To describe the modern treatment of PID. Materials and methods. Analysis of literature sources on this issue; own study to study the effectiveness of the PID treatment with Reosorbilact (“Yuria-Pharm”) and levofloxacin + ornidazole (Grandazole, “Yuria-Pharm”). Women of the main group were additionally prescribed fluconazole, diclofenac, vaginal baths with Dekasan (“Yuria-Pharm”). The treatment lasted 7 days. Treatment of the comparison group included ceftriaxone, metronidazole, diclofenac, doxycycline, fluconazole, chlorhexidine. Results and discussion. Chronic PID often have a latent course. 70 % of them are caused by the specific flora (Chlamydia trachomatis, Neisseria gonorrheae, anaerobes, gram-negative bacteria). The frequency of mixed polymicrobial processes and polychemical resistance is increasing. The presence of bacterial vaginosis allows the infections to recur constantly. Pathogens that cause PID can also cause extragenital pathological conditions (perihepatitis, Reiter’s syndrome, enteritis, colitis, cholecystitis). Diagnostic criteria for PID are the following: pain in the appendages or when the cervix is displaced during the bimanual examination, fever, leukorrhea and menorrhagia. If PID is suspected, a bimanual examination should be performed to rule out acute appendicitis. Ultrasound or computed tomography should be performed to rule out tuboovarian tumors and make a differential diagnosis with intestinal or urinary tract disease. The etiological diagnosis requires microbial and molecular examination of the contents of the vagina and cervix. Fluoroquinolones with metronidazole for 14 days are the first line therapy of uncomplicated PID. Chronic inflammation has no mechanisms of self-completion and can last for years and decades. In gynecology, chronic inflammation is divided into infectious, allergic and autoimmune type. Patients with recurrence of chronic PID are characterized by mixed infections and the formation of biofilms, allergies, low efficiency of immune cells. To overcome the polychemical resistance of pathogens, it is advisable to use effective hydrodynamic drugs that can act as a hydraulic conductor of the antibacterial agent, improve microcirculation in the inflammatory focus, optimize venous hemodynamics and lymphatic drainage. Sorbitol has all these properties. In addition, sorbitol increases the tropism of fluoroquinolones to gram-positive microorganisms and has own bacteriostatic effect. In the own study, it was found that the increase in the resistance index of the ovarian arteries was associated with increased intensity of pain in the lower abdomen, pathological vaginal discharge and fever, which justifies the use of vasoactive drugs in the treatment of PID. In the Reosorbilact and Grandazole treatment groups, normalization of clinical and laboratory parameters occurred in 100 % of women, whereas in 12.1 % of control group members the result was considered insufficient, requiring antibiotic replacement and continuation of therapy. Conclusions. 1. In women with PID, there is a connection between blood flow in the ovarian arteries and the severity of the clinical signs of PID, which justifies the use of hemodynamic drugs. 2. Improvement of intrapelvic hemodynamics on the background of Reosorbilact was the key to successful use of Grandazole. 3. Co-administration of Reosorbilact and Grandazole is a promising method of empirical therapy of PID.

Neuropathic pain (NP) affects approximately 30% of patients with advanced cancer. The prevalence of neuropathic pain related to peripheral neuropathy (NP-RPN) in these patients is not known. The aim of the study was to evaluate NP-RPN prevalence in hospice patients and to find out whether the absence of this pain is sufficient to rule out peripheral neuropathy. The study included a total of 76 patients with advanced cancer who were cared for at inpatient hospices. All patients were asked about shooting or burning pain (of the feet and hands), were examined systematically for sensory deficits and had a nerve conduction study performed. NP-RPN was found in 29% of the patients. Electrophysiologically-diagnosed peripheral neuropathy was found in 79% of patients, and the diagnostic electrophysiological criteria for neuropathy were met by one half of the patients without NP-RPN. The severity of NP-RPN was correlated with the clinically assessed severity of sensory neuropathy and the Karnofsky score, but was not correlated with the intensity of the clinical signs of motor neuropathy. The presence of NP-RPN did not reflect greater prevalence of motor and sensory abnormalities in neurological and electrophysiological examinations. The absence of NP-RPN did not rule out polyneuropathy in hospice patients.

Abstract Background In humans with idiopathic pulmonary fibrosis (IPF), specific thoracic computed tomographic (CT) features in the correct clinical context may be used in lieu of histologic examination. Cats develop an IPF-like condition with similar features to humans. As few cats have invasive lung biopsies, CT has appeal as a surrogate diagnostic, showing features consistent with architectural remodeling supporting “end-stage lung”. Case presentation A 1-year-old female spayed Domestic Shorthair cat presenting with progressive respiratory clinical signs and thoracic CT changes (reticular pattern, parenchymal bands, subpleural interstitial thickening, pleural fissure thickening, subpleural lines and regions of increased attenuation with traction bronchiectasis and architectural distortion) consistent with reports of IPF was given a grave prognosis for long-term survival. The cat was treated with prednisolone, fenbendazole, pradofloxacin and clindamycin. Five months later, while still receiving an anti-inflammatory dose of prednisolone, the cat was re-evaluated with owner-reported absent respiratory clinical signs. Thoracic CT demonstrated resolution of lung patterns consistent with fibrosis. Conclusions Fibrotic lung disease is irreversible. Despite this cat having compatible progressive respiratory signs and associated lung patterns on thoracic CT scan, these abnormalities resolved with non-specific therapy and time, negating the possibility of IPF. While the cause of the distinct CT lesions that ultimately resolved was not determined, infection was suspected. Experimental Toxocara cati infection shows overlapping CT features as this cat and is considered a treatable disease. Improvement of CT lesions months after experimental heartworm-associated respiratory disease in cats has been documented. Reversibility of lesions suggests inflammation rather than fibrosis was the cause of the thoracic CT lesions. This cat serves as a lesson that although thoracic CT has been advocated as a surrogate for histopathology in people with IPF, additional studies in cats are needed to integrate CT findings with signalment, other clinicopathologic features and therapeutic response before providing a diagnosis or prognosis of fibrotic lung disease.

Erythema multiforme is an acute mucocutaneous hypersensitivity reaction with various etiological factors, including herpes simplex virus, medications, autoimmune diseases, and malignancies, but the most common cause is infection by herpes simplex virus. The most characteristic feature is the presence of “target lesions.” There are no specific diagnostic tests for EM, and the diagnosis is based on clinical signs and symptoms and biopsy if required. We report a case of recurrent herpes-associated erythema multiforme managed with prophylactic acyclovir for 6 months: a 17-year-old boy had recurrent cutaneous lesions as well as lesions in the oral cavity and lips. Positive serology for herpes simplex virus and histopathological examination confirmed the diagnosis.

Sebaceous adenitis and concurrent meibomian gland dysfunction (MGD) were diagnosed in a two-year-old mongrel dog presenting with hypotrichosis, exfoliative dermatitis and blepharitis. Diagnosis of sebaceous adenitis was based on history, clinical signs, the histological demonstration of multifocal lymphohistiocytic and neutrophilic inflammation targeting the sebaceous glands and sebaceous glands loss. MGD was diagnosed by non-contact infrared meibography followed by tear film lipid layer interferometric evaluation. Ciclosporin and sebolytic shampoos controlled the dermatological condition, while doxycycline, warm compresses, palpebral massages and tobramycin/dexamethasone ointment controlled the blepharitis. This case report should stimulate clinicians to investigate MGD in dogs suffering from sebaceous adenitis, because the meibomian and sebaceous glands share similar anatomy and physiology.
