ABSTRACT BACKGROUND: Dermatitis herpetiformis (DH) is considered a skin celiac disease (CD). The individuals can be seen by primary care professionals or by dermatologists that could refer the patient to a gastroenterologist. OBJECTIVE: The study aimed to investigate the clinical profile of patients diagnosed with DH and referred to a gastroenterologist and evaluate the treatment response. METHODS: We retrospectively studied patients with DH referred to the same gastroenterologist at a private office in Curitiba, Brazil, between January 2010 to December 2019. We included adult patients with a confirmed DH diagnosis. Symptoms, clinical signs, laboratory and histological data, as well as treatment response, were collected. RESULTS: Thirty-three patients were studied (60.6% women, mean age at diagnosis 40.8±12.61 years). The median delay for DH diagnosis was four years. Skin involvement was mild in 33.3%, moderate in 18.2%, and severe in 48.5%. The more frequent gastrointestinal complaints were abdominal distension (78.8%), flatulence (75.7%), and gastroesophageal reflux (51.5%). Depression and anxiety were observed in 81.8% and anemia in 51.1%. A higher prevalence of bone disorders was associated with higher age at DH diagnosis (P=0.035). Duodenal biopsy showed changes in all patients. Improvement after treatment only with a gluten-free diet (GFD) plus dapsone was verified in 81.2%. CONCLUSION: Patients with DH referred to a gastroenterologist showed a high frequency of gluten intolerance and systemic complaints. Duodenal histological alterations were found in all the cases. The treatment based on GFD plus dapsone was effective in most patients.

Background: Radiography is widely used for diagnosis of congestive heart failure as it enables non-invasive assessment of cardiac size, shape and pulmonary vasculature. So, the present study was conducted to record the radiographic changes in dogs with congestive heart failure.Methods: Fifty-one dogs with cardiac insufficiency brought to Teaching Veterinary Hospital of GADVASU, showing one of the clinical signs of chronic cough, dyspnea, exercise intolerance, abdominal distension, syncope and cyanosis were selected and were subjected to Lateral and Ventro-dorsal chest radiography. Result: Dilated cardiomyopathy was present in 24 dogs. Radiographically, pulmonary edema, cardiomegaly, vessel congestion were more common in dilated cardiomyopathy (DCM). Valvular diseases were present in 16 dogs and radiographically left atrial (LA) dilatation was present in dogs with valvular diseases. Pericardial effusions were present in 11 dogs showing enlarged globoid heart radiographically.

Influenza H7N9 virus is a potentially pandemic subtype to which most people are immunologically naïve. To be better prepared for the potential occurrence of an H7N9 pandemic, in 2017 the World Health Organization recommended developing candidate vaccine viruses from two new H7N9 viruses, A/Guangdong/17SF003/2016 (A/GD) and A/Hong Kong/125/2017 (A/HK). This report describes the development of live attenuated influenza vaccine (LAIV) candidates against A/GD and A/HK viruses and study of their safety and immunogenicity in the ferret model in order to choose the most promising one for a phase I clinical trial. The A/HK-based vaccine candidate (A/17/HK) was developed by classical reassortment in eggs. The A/GD-based vaccine candidate (A/17/GD) was generated by reverse genetics. Ferrets were vaccinated with two doses of LAIV or phosphate-buffered saline. Both H7N9 LAIVs tested were safe for ferrets, as shown by absence of clinical signs, and by virological and histological data; they were immunogenic after a single vaccination. These results provide a compelling argument for further testing of these vaccines in volunteers. Since the A/HK virus represents the cluster that has caused the majority of human cases, and because the A/HK-based LAIV candidate was developed by classical reassortment, this is the preferred candidate for a phase I clinical trial.

ABSTRACT: This study describes the epidemiological, clinical, and pathological aspects of spontaneous and experimental poisoning by nitroxinil at 34% concentration in goats. The outbreak occurred on a farm in the municipality of Prata, Paraíba state. Nitroxinil was administered to a herd of 120 goats, of which 18 presented with anorexia, vocalization, abdominal distension, weakness, staggering, and falls. Necropsy of three goats revealed that the main lesion was acute liver injury. Histologically the liver showed centrilobular necrosis associated with hemorrhage and hepatocyte degeneration. In the kidneys, tubular nephrosis with granular cylinder formations was observed. The lungs showed multifocal to coalescent areas of moderate interalveolar edema and vascular congestion. Experimental poisoning was carried out in two goats, with the same medication and doses administered on the farm. The experimental goats showed clinical signs and macroscopic and histological changes similar to the spontaneously poisoned goats. The diagnosis of nitroxinil poisoning was made based on epidemiological, clinical, and pathological data, and confirmed by experimental poisoning. The administration of nitroxinil in high doses, associated with high ambient temperature and physical exercises, can cause poisoning with high lethality in goats.

Axolotls show a remarkable regeneration capacity compared with higher vertebrates, regenerating missing appendages such as limbs and tail as well as other body parts (i.e., apex of the heart, forebrain, and jaw) after amputations which makes this animal a very interesting research model for tissue regeneration mechanisms. Larvae are individually housed in a 20% Holtfreter’s solution within clear plastic containers. The photoperiod light : darkness cycle is 12 : 12 h. Larvae with a total body length of less than 5 cm are fed once a day with large brine shrimp and blood worm. Albino larvae appeared to have a tendency to exhibit abdominal distention. No clinical signs of illness seemed to be associated with the condition; however, these animals exhibit a relatively slower growth rate. To better characterize this condition, we performed histological sectioning for cross sectional slide preparation on wild type and albino axolotl larvae following euthanasia. The only lesion seen in the albino larvae was a thickened gut wall and the presence of fungi within the intestines. We hypothesize that this may be due to a lower efficacy of the albino larvae’s immune system.

Celiac disease (CeD) is a complex immune-mediated disorder that is triggered by dietary gluten in genetically predisposed individuals. CeD is characterized by inflammation and villous atrophy of the small intestine, which can lead to gastrointestinal complaints, malnutrition, and malignancies. Currently, diagnosis of CeD relies on serology (antibodies against transglutaminase and endomysium) and small-intestinal biopsies. Since small-intestinal biopsies require invasive upper-endoscopy, and serology cannot predict CeD in an early stage or be used for monitoring disease after initiation of a gluten-free diet, the search for non-invasive biomarkers is ongoing. Here, we summarize current and up-and-coming non-invasive biomarkers that may be able to predict, diagnose, and monitor the progression of CeD. We further discuss how current and emerging techniques, such as (single-cell) transcriptomics and genomics, can be used to uncover the pathophysiology of CeD and identify non-invasive biomarkers.

ABSTRACT Clostridium perfringens type C isolates cause enterotoxemias and enteritis in humans and livestock. While the major disease signs and lesions of type C disease are usually attributed to beta toxin (CPB), these bacteria typically produce several different lethal toxins. Since understanding of disease pathogenesis and development of improved vaccines is hindered by the lack of small animal models mimicking the lethality caused by type C isolates, in this study we developed two mouse models of C. perfringens type C-induced lethality. When inoculated into BALB/c mice by intragastric gavage, 7 of 14 type C isolates were lethal, whereas when inoculated intraduodenally, these strains were all lethal in these mice. Clinical signs in intragastrically and intraduodenally challenged mice were similar and included respiratory distress, abdominal distension, and neurological alterations. At necropsy, the small, and occasionally the large, intestine was dilated and gas filled in most mice developing a clinical response. Histological changes in the gut were relatively mild, consisting of attenuation of the mucosa with villus blunting. Inactivation of the CPB-encoding gene rendered the highly virulent type C strain CN3685 avirulent in the intragastric model and nearly nonlethal in the intraduodenal model. In contrast, inactivation of the genes encoding alpha toxin and perfringolysin O only slightly decreased the lethality of CN3685. Mice could be protected against lethality by intravenous passive immunization with a CPB antibody prior to intragastric challenge. This study proves that CPB is a major contributor to the systemic effects of type C infections and provides new mouse models for investigating the pathogenesis of type C-induced lethality.
