Aim. A clinical demonstration of the feasibility of novel superpulsed thulium fibre laser in contact intraductal lithotripsy in patients with choledocholithiasis and pancreatic lithiasis.Key points. We describe two clinically successful ablations of large biliary and pancreatic calculi using a FiberLase U2 superpulse fibre thulium laser appliance (IRE-Polus, Russia) during oral transpapillary cholangiopancreaticoscopy in patients with technically unfeasible conventional minimally invasive treatment for choledocho- and pancreatic lithiasis. A 72-yo patient was urgently admitted with acute mechanical jaundice, cholangitis and a history of endoscopic papillosphincterotomy (EPST) and bilioduodenal stenting with a plastic implant for technically impractical lithotripsy and lithoextraction. An ineffective extracorporeal lithotripsy attempt was followed on day 3 by a second retrograde intervention and endoscopic contact laser lithotripsy controlled in oral transpapillary cholangioscopy with FiberLase U2. A 50-yo patient was admitted with clinical signs of chronic calculous pancreatitis and a history of EPST, pancreatic ductotomy and plastic pancreatic stenting. The first endoscopy stage comprised the encrusted pancreatic stent removal, retrograde pancreaticography, pancreatic ductotomy, narrowed terminal Wirsung’s duct bougienage with mechanical dilators and additional balloon-assisted dilation of the excision area and pancreatic stricture. Mechanical intraductal lithotripsy was unsuccessful. Contact lithotripsy with a novel superpulsed fibre thulium laser has been rendered. The technique presented ensures a complete sanation of the duct at no mucosal damage.Conclusion. We present the fully successful first national and world experience of the superpulsed fibre thulium laser application in contact lithotripsy of large calculi in common bile and main pancreatic ducts.

Ocular tuberculosis (TB) is an extrapulmonary tuberculous condition and has variable manifestations. The incidence of TB is still high in developing countries, and a steady increase in new cases has been observed in industrial countries as a result of the growing number of immunodeficient patients and migration from developing countries. Choroidal granuloma is a rare and atypical location of TB. We present a case of a presumptive choroidal granuloma. This case exposes that diagnosis can be remarkably challenging when there is no history of pulmonary TB. The recognition of clinical signs of ocular TB is extremely important since it provides a clinical pathway toward tailored investigations and decision making for initiating anti-TB therapy and to ensure a close follow-up to detect the development of any complication.

Oesophageal disorders are relatively uncommon in large animals. Oesophageal obstruction is the most frequently encountered clinical presentation in bovine and it may be intraluminal or extra luminal (Haven, 1990). Intraluminal obstruction or “choke” is the most common abnormality that usually occurs when foreign objects, large feedstuff, medicated boluses, trichobezoars, or oesophageal granuloma lodge in the lumen of the oesophagus. Oesophageal obstructions in bovine commonly occur at the pharynx, the cranial aspect of the cervical oesophagus, the thoracic inlet, or the base of the heart (Choudhary et al., 2010). Diagnosis of such problem depends on the history of eating particular foodstuff and clinical signs as bloat, tenesmus, retching, and salivation

A 7-month-old, spayed female, domestic longhair cat with L-2-hydroxyglutaric aciduria (L-2-HGA) was investigated. The aim of this study was to investigate the clinical signs, metabolic changes and underlying genetic defect. The owner of the cat reported a 4-month history of multiple paroxysmal seizure-like episodes, characterized by running around the house, often in circles, with abnormal behavior, bumping into obstacles, salivating and often urinating. The episodes were followed by a period of disorientation and inappetence. Neurological examination revealed an absent bilateral menace response. Routine blood work revealed mild microcytic anemia but biochemistry, ammonia, lactate and pre- and post-prandial bile acids were unremarkable. MRI of the brain identified multifocal, bilaterally symmetrical and T2-weighted hyperintensities within the prosencephalon, mesencephalon and metencephalon, primarily affecting the grey matter. Urinary organic acids identified highly increased levels of L-2-hydroxyglutaric acid. The cat was treated with the anticonvulsants levetiracetam and phenobarbitone and has been seizure-free for 16 months. We sequenced the genome of the affected cat and compared the data to 48 control genomes. L2HGDH, coding for L-2-hydroxyglutarate dehydrogenase, was investigated as the top functional candidate gene. This search revealed a single private protein-changing variant in the affected cat. The identified homozygous variant, XM_023255678.1:c.1301A>G, is predicted to result in an amino acid change in the L2HGDH protein, XP_023111446.1:p.His434Arg. The available clinical and biochemical data together with current knowledge about L2HGDH variants and their functional impact in humans and dogs allow us to classify the p.His434Arg variant as a causative variant for the observed neurological signs in this cat.

Abstract Background Endocrinopathic, or hyperinsulinaemia-associated laminitis (HAL) is a common and debilitating equine foot disease, and although no pharmacological treatments are registered, several are under development. To evaluate the effect of such treatments, an accurate and consistent method is needed to track the clinical signs of laminitis over time, and the natural history of the disease, in terms of a ‘normal’ pattern of improvement, needs to be understood. This study examined the improvement pattern in clinical cases of naturally-occurring HAL subjected to a range of best-practice interventions, using two different scoring methods. Eighty horses and ponies with suspected HAL were enrolled in a study conducted at 16 veterinary practices across Germany. The severity of laminitis was assessed by independent veterinarians using both the traditional Obel method and a modified Obel method developed by Meier and colleagues. Assessments were made on the day of diagnosis (d 0), then on days 4, 9, 14, 25 and 42 during the intervention period. Pain medications were withheld for 24 h prior to clinical examination in all cases. Results Time to marked improvement from laminitis varied between individuals, but was difficult to monitor accurately using the Obel method, with the median grade being 2/4 on days 0 and 4, then 0/4 from d 9 onwards. More subtle changes could be identified using the Meier method, however, and the median scores were seen to follow the form of an exponential decay model in most horses, improving from 8/12 on d 0, to 0/12 on d 25. Within this composite scoring method, considerable variation was observed in the rate of improvement of individual clinical signs, with the average time taken for each sign to reach a median score of 0 ranging from 4 days (foot lift and weight shifting) to 25 days (gait when turned in a circle) across all 80 horses. Conclusions The Meier method provides a reliable and consistent method for monitoring the clinical status of horses with HAL, and despite the variability, the pattern of improvement described here should provide a useful benchmark against which individual cases and new treatments can be assessed.

Introduction: Treating chronic macular edema (CME) post endophthalmitis is a challenge. Use of steroids may reactivate the infection and repeated intravitreal therapy with anti-vascular growth factor inhibitors (Anti-VEGF) puts the patient again at the risk of exacerbation of inflammation or endophthalmitis. We describe a case of CME post traumatic endophthalmitis successfully treated with topical interferon therapy. Case description: A 34-year-old Asian Indian lady with a history of cat bite to her right eye and treated elsewhere as traumatic endophthalmitis with recurrent macular edema, presented to us 1 year after the injury. She had received anti-VEGF injection for same. Her medical history was non-contributory except for close contact with her cat. Therapeutic trials with oral doxycycline followed by oral albendazole with steroids, as well as repeated anti-VEGF therapy failed to prevent recurrence of CME. Patient’s steroid responsiveness and reluctance for injections, made us to opt for a novel topical Interferon therapy. Macular edema resolved in 2 months. Interruption of interferon therapy due to COVID-lock down resulted in recurrence of the CME, which again responded well to interferon monotherapy. Conclusion: Topical interferon may have a role in the treatment of inflammatory macular edema and can serve as a, safer, economical and non-invasive treatment option compared to intravitreal steroids and anti-VEGFs.

Phlegmonous gastritis was diagnosed in 2 yearling fillies that were presented with a 1-wk history of fever, lethargy, and hypoproteinemia, associated with a previous diagnosis of equine proliferative enteropathy based on clinical signs and PCR assay detection of Lawsonia intracellularis in fecal samples. Abdominal ultrasound revealed enlargement of the stomach and expansion of its submucosal layer with hypoechoic fluid, as well as thickened hypomotile small intestinal segments. Given the poor prognosis and poor response to treatment, both horses were euthanized, one on the day of presentation and the other after 3 wk of intensive medical management including a combination of antimicrobials, analgesics, and intravenous colloids. At autopsy, acute mural gastritis characterized by severe submucosal edema with suppurative inflammation (i.e., phlegmonous gastritis) and necroulcerative enteritis compatible with the necrotizing form of equine proliferative enteropathy were identified in both horses. The gastric inflammation was associated with thrombosis and mixed bacterial populations, including Clostridium perfringens, that were confined to the submucosa without evidence of mucosal involvement; toxin genes compatible with C. perfringens type C were identified in one case. Human phlegmonous gastritis is an uncommon, often-fatal pyogenic infection that is often associated with mucosal injury, bacteremia, or immunocompromise. Our finding of this unusual gastric lesion in 2 horses with similar signalment, clinical disease, and spectrum of postmortem lesions suggests a similar etiopathogenesis that possibly involves local, regional, or distant hematogenous origin, and should be considered a potential complication of gastrointestinal mucosal compromise in horses.

ABSTRACT A 10 yr old spayed female toy poodle was presented to a tertiary referral center for a 10 day history of waxing and waning lethargy, vomiting, diarrhea, and anorexia. An immune-mediated neutropenia (IMN) was suspected to be the underlying cause of her clinical signs. A bone marrow aspirate was obtained from the chostochondral junction of the 11th and 12th ribs on the right side and provided a definitive diagnosis of IMN. A positive response to therapy and repeat blood work further confirmed the diagnosis. Obtaining bone marrow aspirates from the chostochondral junction is a safe, cheap, and reliable method of diagnosing IMN and can be performed in the private practice setting with light sedation and minimal need for specialized equipment.

AbstractA 12 year old male Fox Terrier (case 1) and a one year old female Poodle (case 2) were presented with a history of dysorexia and vomiting, and case 2 also with distress associated with eating. Both dogs were diagnosed with acute pancreatitis based on clinical signs, blood analysis and ultrasonography which revealed the presence of a vegetable foreign body in the proximity of the pancreatic right lobe. Laparatomy enabled the gramineae awns to be removed which led to full resolution of clinical signs. We believe that these are the first reported cases of acute pancreatitis due to grass awns.

Abstract Background Thanks to innovation in treatment, people living with HIV and/or HCV now live longer but are growingly facing non-communicable disease burden. HIV-HCV co-infected patients are at high risk of metabolic complications and liver-related events, which are both associated with hepatic steatosis and its progressive form, non-alcoholic steatohepatitis (NASH), a known risk factor for mortality. The fatty liver index (FLI), a non-invasive steatosis biomarker, has recently drawn attention for its clinical prognostic value, but has never been applied to HIV-HCV co-infected patients. We aimed at testing whether elevated FLI (≥60) was associated with all-cause mortality in co-infected patients. Methods Our study is based on data from ANRS CO13 HEPAVIH, a French national prospective cohort of HIV-HCV co-infected patients. Socio-behavioral and clinical data from patients clinically followed-up were used in the analysis. Using a Cox proportional hazards model for mortality from all causes (983 patients; 4,432 visits), we computed hazard ratios associated with risk factors and confounders. Results After multiple adjustment, individuals with FLI≥60 had almost double the risk of all-cause mortality (adjusted hazard ratio [95% confidence interval]: 1.91 [1.17-3.12], p = 0.009), independently of HCV cure (0.21 [0.07-0.61], p = 0.004), advanced fibrosis (1.77 [1.00-3.14], p = 0.05), history of hepatocellular carcinoma and/or liver transplantation (7.74 [3.82-15.69], p < 10-3), history of indirect clinical signs of cirrhosis (2.80 [1.22-6.41], p = 0.015), and HIV CDC clinical stage C (2.88 [1.74-4.79], p < 10-3). Conclusions An elevated fatty liver index is a risk factor for all-cause mortality in HIV-HCV co-infected patients independently of liver fibrosis and HCV cure. In the present era of nearly 100% HCV cure rates, these findings encourage the more systematic use of non-invasive steatosis biomarkers to help identify co-infected patients with higher mortality risk. Key messages A FLI≥60 is strongly associated with mortality in HIV-HCV co-infected patients. FLI could be calculated routinely to identify most at-risk patients.

Introduction. COVID-19 is associated with a significant incidence of bacterial and fungal superinfections and with the exacerbation of pre-existing infections, representing a diagnostic and therapeutic challenge. Case presentation. A 64-year-old woman, confirmed with COVID-19 by the SARS-CoV-2 antigen test, is hospitalized accusing fatigue, nausea, watery stools, cough and vertigo started 10 days ago, aggravated 4 days before the presentation. It also reports recurrent episodes of otalgia and otorrheic pluriantibiotic treatment in the last 2 months. From the personal pathological antecedents we remember: hypothyroidism, dyslipidemia, hypertension, ischemic heart disease, history of deep vein thrombosis (DVT) and secondary pulmonary thromboembolism, in chronic anticoagulant treatment. Pathological clinical signs at admission: bilateral basal crackling rales. Biologically, inflammatory syndrome is detected, and radiologically, interstitial-alveolar infiltrates in the lower lung fields. On day 3 of hospitalization, the patient shows purulent secretion in the right external auditory canal and the ENT consultation confirms chronic suppurative otitis media in acute onset. Bacteriological examination of otic secretion reveals Aspergillus niger. Antiviral treatment with Remdesivir is initiated, antibiotic therapy initiated at home with Azithromycin is continued for one day, then escalated to Ceftriaxone i.v. (in the context of clinical-paraclinical aggravation), systemic corticotherapy, anticoagulation with Dalteparin in the prophylactic regime of DVT, systemic treatment with Voriconazole p.o. (according to the antifungal program) and topical (local) with a slow favorable evolution. Conclusions. The association of COVID-19 with otitis with Aspergillus is a rare and particular clinical picture.
