Efficacy of three different antiseptics as surgical skin preparations in dogsmembers
Various antiseptics are available for surgical skin preparation. The objective of this new study for South Africa was to compare the antimicrobial efficacy of a 2% chlorhexidine gluconate and 70% ethanol solution (CG+A) with that of F10 Skin Prep Solution (F10) and electrochemically activated water (EAW) when used as a surgical preparation in canine patients. One hundred sixteen dogs presented for ovariohysterectomy were enrolled in this prospective randomized clinical study very important for daily surgical practice.

Association between genome and aggression in group-housed pigsmembers
Aggression in groupÔÇÉhoused pigs is a welfare concern and can negatively affect production. Skin lesions are reliable indicators of aggression and are moderately heritable, suggesting that selective breeding may reduce aggression. To further understand the genetic control of behavioral traits, such as the aggressive response to regrouping, associated single nucleotide polymorphisms (SNPs) can be identified within the genome, and the region in which these SNPs are located can be related to known genes. A fascinating approach to this problem!

Efficacy of three antiseptics as surgical skin preparations members
Which of the three commonly used antiseptics is the most efficacious? This new prospective randomized clinical study compares the antimicrobial efficacy of a 2% chlorhexidine gluconate and 70% ethanol solution (CG+A) with that of F10 Skin Prep Solution (F10) and electrochemically activated water (EAW) when used as a surgical preparation in canine patients. The patients: 116 bitches presented for ovariohysterectomy.

Staining hair samples with a modified Wright-Giemsa stain to diagnose feline dermatophytosismembers
Direct examination of the hair is a simple diagnostic test for the diagnosis of dermatophytosis; training is needed to use this test. This study tried to evaluate whether use of modified WrightÔÇôGiemsa blue stain and/or photographic images of infected and uninfected hairs improved the user`s ability to identify infected or uninfected hairs. Ten cats with, and 10 cats without, dermatophytosis due to Microsporum canis (n = 20) were enrolled.

A pigment retinopathy has been reported in adult horses with equine motor neuron disease (EMND) arising from chronic ╬▒-tocopherol (╬▒-TP) deficiency. A pigment retinopathy has not been identified in horses with neuroaxonal dystrophy/equine degenerative myeloencephalopathy (NAD/EDM) that affects genetically susceptible young horses with ╬▒-TP deficiency. The objective of this report is to describe, for the first time, a pigment retinopathy in a family of ╬▒-TP-deficient Warmbloods (WB) with clinically apparent NAD/EDM or EMND.

Inguinal percutaneous ultrasound to locate cryptorchid testes in horsesmembers
Standing laparoscopic removal of abdominally retained cryptorchid testes may reduce patient morbidity and speed recovery compared with traditional laparotomy because anaesthesia is avoided and skin incisions are smaller. Reliably locating the testis preoperatively is therefore optimal to avoid unnecessary surgical morbidity and expense. The authors describe and review the results of a simple method of location using ultrasound scanning of the inguinal region, with a negative result indicating abdominal Retention, developed on more than 170 horses.

Transcriptome analysis of sarcoids in horsesmembers
Equine sarcoids are the most commonly detected skin tumours in Equidae. In the present research, a comparative transcriptomic analysis was performed which aimed at looking inside a tumour biology and identification of the expression profile as a potential source of cancer specific genes useful as biomarkers.

Atopic dermatitis and the intestinal microbiota in dogs and menmembers
The prevalence of human and canine allergic diseases is commonly perceived to be increasing. Suggested predisposing factors in people and dogs include increased allergen load, increased exposure to pollutants, reduced family size, reduced microbial load and less exposure to infection at a young age, increasingly urbanised environment, and changes in dietary habits. Genetic make-up may provide a template for phenotypic predisposition which is strongly influenced by our diet and environment leading to constant regulation of gene expression. One way in which diet can alter gene expression is via its effects on the gut flora or microbiota, the collection of microbes residing in the gastrointestinal tract. A very interesting new aspect in the pathogenesis of atopic Dermatitis in both humans and dogs!

2-tier histologic grading system for canine cutaneous mast cell tumors on cytology members
Mast cell tumors (MCT) represent the most common malignant skin tumor in the dog. Diagnosis of an MCT can be achieved through cytologic examination of a fine-needle aspirate. However, the grade of the tumor is an important prognostic marker and currently requires histologic assessment. Recently a 2-tier histologic grading system based on nuclear features including number of mitoses, multinucleated cells, bizarre nuclei, and karyomegaly was proposed. The aim of this study was to assess if the cytomorphologic criteria proposed in the 2-tier histologic grading system are applicable to cytology specimens.

Atopic dermatitis and the intestinal microbiotamembers
The prevalence of human and canine allergic diseases is commonly perceived to be increasing.

Biophysical evaluation for mapping of the canine skinmembers
Trans epidermal water loss (TEWL), skin hydration status and pH were determined in 14 skin regions of five healthy male Beagle dogs (2┬ľ4 years) both before and after anaesthesia. Trans epidermal water loss was highest for the footpad and head and lowest for the inguinal region. Skin hydration status was higher in the ear but did not vary significantly in other regions.

Do cellular blue naevi exist in horses?members
Melanocytic tumours are important in horses, especially grey horses. In human medicine, intradermal common melanocytic naevi, cellular blue naevi and combined cellular blue naevi are desscribed as subgroups of melanocytic tumours. In equine medicine these tumours have not been reported. But does this really mean that they do not exist?

New insights in the pathogenesis of equine sarcoidsmembers
The equine sarcoid is the most common dermatologic neoplasm reported in horses. Bovine papillomavirus (BPV) types 1 and 2 are associated with sarcoids, in which the expression of the major transforming oncoprotein (E5) is often recorded. The transformation activity of the virus is due to the binding of the E5 to the platelet-derived growth factor â receptor (PDGFâ-r). This fascinating little study offers more insights in the pathogenesis and thus hopefully leads to better therapeutic options in the future...

Bandaging and second intention wound healing in horses with distal limb woundsmembers
Wounds on the distal limbs of horses often tend to secondary infections, delayed healing or healing with excessive granulation tissue.

Exudative epidermitis (EE) is an acute, often fatal skin disease of piglets caused by toxins produced by Staphylococcus hyicus. Clinical and histopathological manifestations of EE are similar to those of staphylococcal scalded skin syndrome (SSSS) in humans.

S-Adenosyl-L-Methionine (SAMe) as antidote in acetaminophen toxicity
Intoxications are commonly seen in the emergency care units, and mostly young dogs are affected. Not always are antidots available. This interesting case report documents that S-Adenosyl-L-Methionine (SAMe) is an effective therapeutic option in acetaminophen toxicity.

Itraconazole pulse therapy in dogs with malassezia dermatitis
Azoles are proven to be very effective in the therapy of malassezia dermatitis in dogs. The `classic` azole for this indication is ketoconazole which is given one to three times a day. Is itraconazole pulse therapy a good alternative as it is in feline and human dermatophytosis? An interesting study presented at the 20th Annual Congess of the European Society of Veterinary Dermatology in Chalkidiki!

Prevalence of house dust mite-antigen in houses with and without dogs
A very interesting study with surprising results! House dust mite allergens, which are described as the most common allergens in dogs and men with atopy, are found in living rooms in high concentrations - not surprising. But their concentration is significantly higher in the households without dogs - really surprising. Is flea prevention the explanation for this?

Skin myxoma in a dog (case report)
An extremely rare neoplasia in dogs! This very interesting case report describes a terrier from Iran which was presented with a large mass on a hindleg without any systemic signs. Surgical removal was curative.

Bilateral ear canal neoplasia in dogs
A common problem in dogs: proliferative changes of the ear canal which represent the final stage of a chronic otitis. But although this is by far the most common reason, other differentials like neoplasia also need to be considered. They can occur bilaterally, as this interesting case report shows!

Doramectin against scabies in rabbits
Doramectin, ivermectin and moxidectin are known to be effective against Sarcoptic mange in dogs. Moxidectin was described to be only partial effective in rabbits which is rather surprising. In this study, doramectin is chosen to treat scabies infestation in the very sensitive Angora rabbits. It works!

Intermediate steroid hormone levels in dogs with Alopecia X
Alopecia X remains a skin disease with an unclear pathogenesis. Evaluation of several hormon blood levels have been not very diagnostic in the past. This interesting study compares the interemdiate steroid levels before and during different therapies.

Skin metastases of a bronchial adenocarcinoma in a cat (case report)
Skin metastases of adenocarcinomas are sometimes seen in dogs, most often deriving from a primary mammary adenocarcinoma. This description of a metastatic bronchial adenocarcinoma in a cat is very interesting and seems to be unique. Or do some of our “miliary dermatitis” cats have skin tumours?

Zinc-responsive probably hereditary dermatosis in goats
Two extremely interesting cases have been described an the University of Vienna: two goats with a zinc-responsive dermatosis which is suggestive of hereditary malabsorption. This syndrome is well known in certain dog breeds like Sibirean Huskies and Alaskan Malamutes. May be it also exists in other species...

Leishmania spp. and Mycobacterium spp. in canine cutaneous `sterile` pyogranuloma/granuloma syndrome
Cutaneous `sterile` pyogranuloma/granuloma syndrome (SPGS) is an uncommon canine skin disorder of unknown aetiopathogenesis - ofting leading to chronic or chronic-relapsing problems and frustrating both owners and veterinarians. Did you ever think about Leishmania or Mycobacterium as a causing agent? A fascinating idea at least in endemic regions!

Manifestations of exfoliative cutaneous lupus erythematosus in German short-haired pointers
Exfoliative cutaneous lupus erythematosus is an uncommon generalized exfoliative dermatitis occurring exclusively in German short-haired pointers. The disease might be underdiagnosed even by veterinary dermatologists. This excellent summary characterized the findings of 25 affected dogs.

Different serum immunoreactivity to Malassezia pachydermatis in dogs
Canine sera which are tested with Malassezia extract often show different results. Why? One explanation might be that there is variation in antigenic expression in different growth phases of M. pachydermatis. A very interesting new study!

Immunostimulatory liposome-nucleic acid complexes in allergen-specific immunotherapy of dogs with AD
Specific immunotherapy is known to be an effective and safe therapy in canine atopic dermatitis. Its efficacy is described up to 77 percent. But what happens with the `non-responders`? Is this new type of immunotherapy a promising option? A very interesting pilot study which also has been presented as a short communication on the World Congress of Veterinary Dermatology in Vienna last year.

Hereditary regional dermal asthenia in three Brazilian Quarter horses
Dermal asthenia is described in several species and is known to be a congenital dysplasia of the connective tissue. Diagnosis is not too difficult if one deals with a generalized problem. But what if the problem is only regional? A very interesting study on three related Quarter horses, focussing on clinical and histopathological findings!

Terbinafine versus ketoconazole in canine malassezia dermatitis
Azoles and especially ketoconazole have become the drugs of choice in the therapy of malassezia dermatitis in dogs. Terbinafine is a antimycotic drug which is well tolerated and safe and has been used very successful in canine dermatophytosis. Is it also a good option to treat yeasts?

Are human and canine staphylococci species specific?
It seems so - staphylococcus intermedius is by far the most common isolated bacterium in canine pyoderma whereas staphylococcus aureus is the human `counterpart`. Is there really a species specificity in the adherence to human and canine skin? A very interesting study from Scotland!

Castration and gestagen therapies in male dogs
Every veterinarian knows that certain diseases and behavioural problems in intact male dogs are common, e.g. perineal hernia, benign prostatic hyperplasia, anal adenoma, testicular neoplasms and sex-hormone dermatoses. In this excellent paper, a review of the literature regarding castration, progestagen treatment and the most common side effects is performed. One result: there are alternatives to castration!

Heat shock proteins expression in canine skin tumors
Heat shock proteins (HSPs) are strongly implicated in the control of cell growth, differentiation and biological behaviour of many human cutaneous neoplasms. Less is known about them in veterinary medicine. Are they useful in differentiation of different skin tumors, like intracutaneous cornifying epithelioma and squamous cell carcinoma? A new and interesting study from Italy.

Role of IgE in equine urticaria
Compared with other species, urticaria is a common phenomenon in horses. But we know only a few about the pathogenesis. This brand new publication from Switzerland suggests that IgE might play an important role in the pathogenesis - after the histopathological examination of skin biopsies and special staining.

Acral mutilation and analgesia in French spaniels
An acral mutilation syndrome has been described as an hereditary disease in German short-haired pointers. But also French spaniels can suffer from a similar diseaase that has been described now for the first time...

Cutaneous neosporosis in a dog with pemphigus foliaceus
Pemphigus foliaceus is one of the most common autoimmune diseases in dogs. Its therapy consists of immunosuppressive drugs, the therapy of choice is the combination of prednisolone and azathioprine. It is well known that this therapy can also reduce the cutaneous immune systeme and favour infections with dermatophytes. But also with organisms like neospora, at least in certain climates, as this case report from Spain documents.

Intravenous fluorescein in intradermal allergy testing in birds
Intradermal skin tests are a standard procedure to identify causing allergens in various species. In some species like cats positive results can be hard to see and so studies were undertaken to decrease this problem by the i.v. injection of fluorescein. In birds, the whole thing is even more difficult, and intradermal tests are said to be unreliable. Does fluorescein give better results?

Prevalence of house dust mite allergens in the UK
The United Kingdom is known to be a very special part of Europe. Also the prevalence of Der f 1 antigen in british households differs from `Continental Europe`, as this interesting brandnew article shows!

Adult-onset hair loss in Chesapeake Bay retrievers

Do eczema drugs increase the risk of cancer?
Tacrolimus (Protopic) and Pimecrolimus (Elidel) have become popular drugs to treat atopic eczema in humans, especially in children, and they are more and more used in certain skin disorders like DLE and atopic dermatitis in animals. Do they increase the risk to develop cancer like lymphomas? The FDA gave an official press release yesterday...

Cutaneous microflora in horses with and without skin diseases
The cutaneous microflora of dogs without skin problems, dogs with seborrhoic diseases or allergic dermatoses is well evaluated. Surprisingly, less is known about the equine cutaneous microflora. This brandnew study from Cornell University gives some interesting new insights: For example, equine hyperkeratotic skin is significantly associated with an increased number of surface bacteria.

Topical pimecrolimus in canine KCS
Keratoconjuctivitis sicca (KCS) is a common eye disease in certain breeds. The most popular current therapy consists is the application of a topical cyclosporin A-preparation. In dermatology, other cyclosporin-relatives like tacrolimus or pimecrolimus are used topically for months or even years with good results. Is pimecrolimus also a new alternative in the eye?

Immunohistochemistry in dogs with VKH-like syndrome
Vogt-Koyanagi-Harada (VKH)-like syndrome or uveodermatological syndrome (UVD) occurs in certain breeds and is characterized by a severe autoaggression directed against melanocytes. This brandnew study of tissues of 2 dogs shows very interesting news - the cell response of eye and skin is different which might explain the clinical difference in the level of inflammation!

Only every fifth dog had known tick exposure

Clindamycin once daily in canine pyoderma
The treatment of canine pyoderma with `staphylococcal-effective` antibiotics can become very expensive, especially if large dogs need to be treated over weeks. Is clindamycin given only once daily an effective therapeutic option? Might be!

Pyotraumatic dermatitis: new insights in histopathology
Pyotraumatic dermatitis (hot spot) is a common clinical syndrome in dogs but there are few prospective scientific studies related to it. It is easy to diagnose and to treat and so almost never skin biopsies for histopathology are taken. But if this is done, surprising results occur, as this brandnew study demonstrates.

Bacteria isolates from skin and ears over 6 years
Staphylococcus intermedius is by far the most common bacteria isolated in superficial pyoderma, and Pseudomonas aeruginosa is commonly involved in ear infections. Did their frequency change over the years, and did their antibacterial resistance change. Very important questions for adequate therapy- One of the results of this retrospective study: Psueudomonas ear infections are raising, and one should always do antibiogramms when Pseudomonas aeruginosa is isolated.

`Food allergens` of lamb, beef and cow┬┤s milk identified?
Adverse cutaneous reactions to food ingredients are sometimes seen in dogs and cats and can be difficult to identify. In this interesting recently published study from Spain the proteins responsible for cutaneous adverse reactions to these foods are identified, as the authors say...

Seasonal insect bite hypersensitivity in sheep
Dermatitis due to hypersensitivity to certain insects like the cat flea Ctenocephalides felis felis or to midges like Culicoides are well described in small animals and in horses. But why should sheep not show allergies to these insects? This brandnew study from Israel suggests that these reactions might be underestimated!

Do we use the wrong allergen concentrations for intradermal skin testing?
Intradermal skin test (IDT) is thought to be the gold standard to identify the causing allergens in canine atopic dermatitis. But are the allergen concentrations we use adequate? A substantial question, and the result of this recently published study says: most of our histamine and allergen concentrations are not optimal!

Corynebacterium pseudotuberculosis outbreak causes skin lesions and mastitis
Mastitis is a well-known sign for a corynebacterium pseudotuberculosis infection. But this very interesting article from Israel describes a corynebacterium pseudotuberculosis outbreak in a dairy cattle herd causing both ulcerative granulomatous skin lesions and mastitis.

Prednisone or prednisolone in the feline patient?members
Over many years, prednisone and prednisolone given to both dogs and cats were believed to be absolutely the same regarding bioavailability, effect and tolerance. But is this really true? This question was raised by an American study group and evaluated carefully. The surprising result: oral prednisolone is the superior choice for cats!

Superficial necrolytic dermatitis in a cat: diagnostic findings (case report)
Superficial necrolytic dermatitis (“hepatocutaneous syndrome”) is diagnosed sometimes in older dogs and rarely in cats. It is characterized by both severe alterations of the liver (neoplasia, cirrhosis etc.) and by severe crusty skin lesions especially of the footpads and the mucocutaneous junctions in dogs. The skin lesions in this cat were completely different: it showed a pruritic alopecia.

Patch tests with house dust mite antigen in dogs
Patch tests are routinely performed in men in the diagnosis of atopic dermatitis. For several reasons, they are not very popular in canine dermatology. This interesting study describes the results of patch tests with house dust mite antigen in 13 dogs with atopic dermatitis. One of the results: These mites penetrate the skin of the allergic animals and induce an inflammatory response...

Intradermal or allergen-specific IgE tests in seasonal atopic dermatitis?
For many years, intradermal skin tests were and are believed to be the `gold standard` to identify the causing allergens in dogs with atopic dermatitis. One of the most famous dermatologists, Ed Rosser, compared the results of both tests in 29 dogs with seasonal signs. The result: the optimum would be the simulatneous use of both tests!

Canine distemper virus in epidermis of the footpads
Severe hyperkeratosis of the footpads, `hard pad disease`, is one of the clinical manifestations of canine distemper. But what happens in the epidermis? A team from Switzerland and Germany did histopathological and immunhistochemical studies and found a noncytocidal persisting infection of footpad keratinocytes by the distemper virus.

Sex hormone intermediates in dogs with alopecia
Alopecia in dogs in often induced by hormonal imbalances, e.g. hypothyroidism or hyperadrenocorticism. But what if these are excluded? Steroid and sex hormone intermediates are sometimes measured. But: This study shows, that the evaluated parameters show significant breed-specific variations and `breed specific normal values` would be needed.

Oral cyclosporin in canine end stage otitis
Otitis externa is a common problem in dogs, leading to chronic proliferative and sometimes even calcifying tissue changes which cause a stenosis of the ear canal. In most instances, surgery is the only solution in these cases. Is cyclosporin A an alternative to total ear canal ablation?

Dermoid cyst in the dorsal midline of a young horse (case report)
Dermoid cysts are well known in other species and occur especially in certain breeds on a genetic base (e.g. Rhodesian Ridgeback). In horses, they seem to be extremely rare. This case report describes the first epidermal and dermoid cysts in a horse outside Australia and North America.

Topical 0,1% tacrolimus in canine atopic dermatitis
Topical tacrolimus is commonly used in men with atopic dermatitis, especially in children. It offers many advantages compared with topical corticosteroids, showing similar results but less topic and systemic side effects. Is this drug also a good alternative in veterinary medicine?

`Irritant` threshold concentration for insect extracts in equine skin testing
Allergies to a number of insects are commonly seen in horses, showing various clinical manifestations. As in small animals, the intrademal skin test is thought to be the `gold standard` to identify the causative allergens. But how many false-positive results do we see, due to irritant allergens?

Pelvic fractures and the skin
Pelvic fractures are commonly found in cats, often caused by injury. After recovery, fortunately most of them show no sequelae of other organ systems. In this article from Belgium, the author describes three cats that developed similar skin alterations of the lower back about one month after pelvic fracture.

Update in treatment of dermatophytosis in dogs and cats
Dermatophytosis is a common problem especially in cats. Lots of controversial information concerning therapy have been published in the last couple years. Karen Moriello, one of THE experts in this field, gives a brandnew and critical review of the published studies and thus the current therapeutic options.

Hand and forearm dermatoses in veterinarians
Veterinarians are daily exposed to a variety of skin irritants and allergens. At the moment, only a few studies have addressed the occurrence of dermatoses among veterinarians. In this study from Kansas, the frequency of noninfectious hand and forearm dermatoses among Kansas veterinarians and the benefit from using gloves was evaluated.

Preoperative warming to reduce wound infections?
Wound infection after clean surgery is an expensive and often underestimated cause of patient morbidity. The benefits of using prophylactic antibiotics are seen controversially. Is warming the patients an alternative to reduce wound infections?

Interdigital dermatitis - update in therapeutic options
Even with treatment, digital dermatitis or foot warts remain a chronic problem for many dairy herds. Steven Berry, dairy health and management specialist at the University of California-Davis explains, `Research shows that up to 60 percent of cows that are successfully treated for foot warts have a recurrence within seven to 15 weeks.`
Maybe a new vaccine will change the situation...

Intradermal allergy test in psittacines: unreliable with and without intravenous fluorescein
The intradermal skin test is thought to be the `gold standard` in the diagnosis of atopic dermatitis. Unfortunately, the results often are not easy to read, especially in cats. So some years ago the technique was modified: fluorescein was given intravenously prior to the test to stain the positive results. An american group tried the same technique in psittacines...

New technique for skin biopsies in birds
Skin biopsies are a viable diagnostic tool in dermatology and therefore also taken in birds. Due to the very thin avian skin, their biopsies have the tendency to roll or contract, both leading to severe difficulties to separate artefacts from real pathological changes. This new biopsy technique using a tapestrip is quick, inexpensive and gives good results.
