Diagnosis and successful management of a rare case of phaeohyphomycosis in a Doberman pinscher dog.

ABSTRACT: Skin affections in canines are common and their treatment depends upon the pathogens involved. Delayed or no response to traditional treatment indicates the involvement of unusual etiology or the multidrug resistance. This report describes the diagnosis and therapeutic management of a rare case of phaeohyphomycosis caused by Alternaria alternata complicated with Pseudomonas aeruginosa associated pyoderma in a Doberman pinscher dog. Identification of the etiological agents was based on microscopy and culture of the skin lesions and further confirmation by polymerase chain reaction (PCR) amplification. Treatment consisted of a combination of systemic antifungal and antibacterial drugs selected on the basis of in vitro antimicrobial susceptibility tests along with the tropical therapy. The report hightlights the need of studies on opportunistic fungi to better understand the associated risks, pathogenesis and optimal treatment of these uncommon infections.

A homozygous ADAMTS2 nonsense mutation in a Doberman Pinscher dog with Ehlers Danlos syndrome and extreme skin fragility.

Project description:An eight-week old Doberman Pinscher was diagnosed with Ehlers Danlos syndrome based on the dog's hyper-mobile carpal, tarsal and stifle joints and abnormal skin. The skin was loose and hyper-elastic with several wounds and large atrophic scars. The dog was euthanized after a severe degloving injury from minimal trauma. A whole-genome sequence, generated with DNA from the dog's blood, contained a rare, homozygous C-to-T transition at position 2408978 on chromosome 11. This transition is predicted to alter the ADAMTS2 transcript (ADAMTS2:c.769C>T) and encode a nonsense mutation (p.Arg257Ter). Biallelic ADAMTS2 mutations have caused a type of Ehlers Danlos syndrome known as dermatosparaxis in other species.

Functional Consequences of PDK4 Deficiency in Doberman Pinscher Fibroblasts.

Project description:A splice site mutation in the canine pyruvate dehydrogenase kinase 4 (PDK4) gene has been shown to be associated with the development of dilated cardiomyopathy (DCM) in Doberman Pinchers (DPs). Subsequent studies have successfully demonstrated the use of dermal fibroblasts isolated from DPs as models for PDK4 deficiency and have shown activation of the intrinsic (mitochondrial mediated) apoptosis pathway in these cells under starvation conditions. For this study, we sought to further explore the functional consequences of PDK4 deficiency in DP fibroblasts representing PDK4wt/wt, PDK4wt/del, and PDK4del/del genotypes. Our results show that starvation conditions cause increased perinuclear localization of mitochondria and decreased cell proliferation, altered expression levels of pyruvate dehydrogenase phosphatase (PDP) and pyruvate dehydrogenase (PDH), dramatically increased PDH activity, and an impaired response to mitochondrial stress in affected cells. In sum, these results show the broad impact of PDK4 deficiency and reveal mechanistic pathways used by these cells in an attempt to compensate for the condition. Our data help to elucidate the mechanisms at play in this extremely prevalent DP disorder and provide further support demonstrating the general importance of metabolic flexibility in cell health.

A partial gene deletion of SLC45A2 causes oculocutaneous albinism in Doberman pinscher dogs.

Project description:The first white Doberman pinscher (WDP) dog was registered by the American Kennel Club in 1976. The novelty of the white coat color resulted in extensive line breeding of this dog and her offspring. The WDP phenotype closely resembles human oculocutaneous albinism (OCA) and clinicians noticed a seemingly high prevalence of pigmented masses on these dogs. This study had three specific aims: (1) produce a detailed description of the ocular phenotype of WDPs, (2) objectively determine if an increased prevalence of ocular and cutaneous melanocytic tumors was present in WDPs, and (3) determine if a genetic mutation in any of the genes known to cause human OCA is causal for the WDP phenotype. WDPs have a consistent ocular phenotype of photophobia, hypopigmented adnexal structures, blue irides with a tan periphery and hypopigmented retinal pigment epithelium and choroid. WDPs have a higher prevalence of cutaneous melanocytic neoplasms compared with control standard color Doberman pinschers (SDPs); cutaneous tumors were noted in 12/20 WDP (<5 years of age: 4/12; >5 years of age: 8/8) and 1/20 SDPs (p<0.00001). Using exclusion analysis, four OCA causative genes were investigated for their association with WDP phenotype; TYR, OCA2, TYRP1 and SLC45A2. SLC45A2 was found to be linked to the phenotype and gene sequencing revealed a 4,081 base pair deletion resulting in loss of the terminus of exon seven of SLC45A2 (chr4∶77,062,968-77,067,051). This mutation is highly likely to be the cause of the WDP phenotype and is supported by a lack of detectable SLC45A2 transcript levels by reverse transcriptase PCR. The WDP provides a valuable model for studying OCA4 visual disturbances and melanocytic neoplasms in a large animal model.

Disseminated phaeohyphomycosis in a dog.

Project description:Phaeohyphomycosis is a rare but emerging disease caused by dematiaceous fungi. Here we describe the case of an immunosuppressed dog with disseminated phaeohyphomycosis secondary to Bipolaris spicifera infection. Regionally extensive infiltration of the paw pads, skin, myocardium, liver, renal interstitium and diaphragm was identified on histopathology. Candida glabrata and Fusarium oxysporum were also cultured from multiple sites post-mortem. The dog was treated with fluconazole, itraconazole, terbinafine and liposomal amphotericin B, but was euthanized due to its poor prognosis after 12 days of therapy.

A predictive model for canine dilated cardiomyopathy-a meta-analysis of Doberman Pinscher data.

Project description:Dilated cardiomyopathy is a prevalent and often fatal disease in humans and dogs. Indeed dilated cardiomyopathy is the third most common form of cardiac disease in humans, reported to affect approximately 36 individuals per 100,000 individuals. In dogs, dilated cardiomyopathy is the second most common cardiac disease and is most prevalent in the Irish Wolfhound, Doberman Pinscher and Newfoundland breeds. Dilated cardiomyopathy is characterised by ventricular chamber enlargement and systolic dysfunction which often leads to congestive heart failure. Although multiple human loci have been implicated in the pathogenesis of dilated cardiomyopathy, the identified variants are typically associated with rare monogenic forms of dilated cardiomyopathy. The potential for multigenic interactions contributing to human dilated cardiomyopathy remains poorly understood. Consistent with this, several known human dilated cardiomyopathy loci have been excluded as common causes of canine dilated cardiomyopathy, although canine dilated cardiomyopathy resembles the human disease functionally. This suggests additional genetic factors contribute to the dilated cardiomyopathy phenotype.This study represents a meta-analysis of available canine dilated cardiomyopathy genetic datasets with the goal of determining potential multigenic interactions relating the sex chromosome genotype (XX vs. XY) with known dilated cardiomyopathy associated loci on chromosome 5 and the PDK4 gene in the incidence and progression of dilated cardiomyopathy. The results show an interaction between known canine dilated cardiomyopathy loci and an unknown X-linked locus. Our study is the first to test a multigenic contribution to dilated cardiomyopathy and suggest a genetic basis for the known sex-disparity in dilated cardiomyopathy outcomes.

Case Report: Successful Management of Conidiobolus Lamprauges Rhinitis in a Dog.

Project description:This is a case of Conidiobolus lamprauges rhinitis in a Goldendoodle, that was presented for evaluation of sneezing, coughing, lethargy, as well as right-sided epistaxis and clear ocular discharge. Computed tomography revealed a large amount of soft tissue within the right nasal passage that obscured the osseous turbinates from the right maxillary canine tooth to the right side of the choanae. Biopsies revealed eosinophilic granulomas with variable number of basophilic to negatively staining, septate, fungal hyphae with non-parallel walls and irregular branching that were subsequently determined to be Conidiobolus lamprauges via panfungal PCR and sequencing. Complete and sustained resolution of clinical disease was achieved after 75 days of systemic antifungal therapy. This report describes for the first time, important clinical features of a dog with nasal conidiobolomycosis that will facilitate its recognition, prognostication, and treatment in clinical practice.

A Rare Case of Ribbing Disease- Diagnosis and Management.

Project description:IntroductionRibbing diseases is rare and have only been occasionally reported. We here in report a case of Ribbing disease affecting bilateral tibia which was diagnosed based on computed tomography (CT), magnetic resonance imaging (MRI), and histopathological features and managed by intramedullary reaming .Case reportA 45 - year - old female presented with complaints of pain in the right leg for the past four 4 months duration and the patient had similar complaints of pain in the left leg 3 years back for which she had had taken treatment at an outside hospital where she underwent saucerization of the left tibia as a case of low- grade osteomyelitis . To evaluate the cause of pain X-ray, CT and, MRI were done which were suggestive of Ribbings disease and biopsy was performed which favoured the diagnosis of Ribbings disease. The patient was tried on a course of analgesics , with no symptomatic betterment , after going through the literature, the patient was taken up for the right tibia intramedullary reaming. Post operatively, the patient symptomatically improved and is pain free for the past 4 years.ConclusionRibbing disease is an uncommon cause of a common symptom. It is a rare diaphyseal sclerosing dysplasia. With lack of clinical signs of infection and biochemical evidence of metabolic bone disease and positive clinical, radiological and histological features in favour of ribbing disease helped us in arriving at the diagnosis. Intramedullary reaming of the affected bone has been useful in providing symptomatic betterment .

Successful management of a recurrent 180° uterine torsion: a rare case report

Project description:Abstract Uterine torsion (UT) is one of the most uncommon obstetric complications. It usually occurs in the third trimester. The confirmed diagnosis relies on > 45° rotation at the utero-cervical junction around its longitudinal axis. The etiology is unknown in 20% of cases. It might be asymptomatic in some rare cases; however, symptoms usually manifest with acute abdominal pain, fetal bradycardia, vaginal bleeding or failure of labor progress. Laparotomy is used to establish the diagnosis and the management of UT. We report a 180° uterine dextrotorsion case of an obese 24-year-old pregnant female who presented with severe abdominal pain at the 35th gestational week, which was diagnosed and managed by an emergency laparotomy. UT is a rare though serious condition and must be doubted before a suspicious clinical image. Therefore, it is suggested to avoid consecutive pregnancies and the resultant uterine rupture.

Deafness and vestibular dysfunction in a Doberman Pinscher puppy associated with a mutation in the PTPRQ gene.

Project description:BackgroundA congenital syndrome of hearing loss and vestibular dysfunction affects Doberman Pinschers. Its inheritance pattern is suspected to be autosomal recessive and it potentially represents a spontaneous animal model of an autosomal recessive syndromic hearing loss.Hypothesis/objectivesThe objectives of this study were to use whole genome sequencing (WGS) to identify deleterious genetic variants in candidate genes associated with the syndrome and to study the prevalence of candidate variants among a population of unaffected Doberman Pinschers.AnimalsOne affected Doberman Pinscher and 202 unaffected Doberman Pinschers.MethodsWGS of the affected dog with filtering of variants against a database of 154 unaffected dogs of diverse breeds was performed. Confirmation of candidate variants was achieved by Sanger sequencing followed by genotyping of the control population of unaffected Doberman Pinschers.ResultsWGS and variant filtering identified an alteration in a gene associated with both deafness and vestibular disease in humans: protein tyrosine phosphatase, receptor type Q (PTPRQ). There was a homozygous A insertion at CFA15: 22 989 894, causing a frameshift mutation in exon 39 of the gene. This insertion is predicted to cause a protein truncation with a premature stop codon occurring after position 2054 of the protein sequence that causes 279 C-terminal amino acids to be eliminated. Prevalence of the variant was 1.5% in a cohort of 202 unaffected Doberman Pinschers; all unaffected Doberman Pinschers were heterozygous or heterozygous for the reference allele.Conclusion and clinical importanceWe report the identification of a genetic alteration on the PTPRQ gene that is associated with congenital hearing and vestibular disorder in a young Doberman Pinscher dog.
