Background: Pilomatricomas are neoplasms of hair follicles, located in the hair bulb, and the incidence is uncommon in the clinical-surgical clinical routine of dogs and cats. It commonly affects adult animals, with no predisposition to sex or race, and is mainly located in the neck, back, and tail region. The diagnosis is made by histopathological examination, where cells are observed in which their nucleus does not stain with hematoxylin and eosin - empty nucleus. The present work aimed to report a case of benign pilomatricoma since it is a rare condition in dogs and cats and, consequently, there is little information in the literature. Case: A 6-year-old male Shih-Tzu dog, not submitted to surgical contraception, weighing 6.9 kg, was treated at the Veterinary School Hospital (HVE) of the North Parana State University (UENP), Bandeirantes, PR, Brazil, with a history of nodules in the tail region, lasting 6 months. On physical examination, no changes were identified in the patient's physiological parameters. However, the presence of neoformations in the distal and medial region of the tail, similar to a nail, adherent, non-ulcerated and non-alopecic, and absence of pruritus or self-mutilation were identified. Vaccination and deworming were updated. Hematological examination, serum biochemicals (urea, creatinine, alanine aminotransferase, alkaline phosphatase, and albumin), and abdominal ultrasound showed no changes. According to the clinical and laboratory signs, it was decided to perform an excisional biopsy, using a caudectomy, for subsequent histopathological examination. The specimens were fixed in 10% formaldehyde and sent for histopathological examination. Histological examination was compatible with benign pilomatricoma. Postoperatively, cephalexin, dipyrone, tramadol hydrochloride, and meloxicam were prescribed, surgical wound cleaning, and the use of an Elizabethan collar until the suture was removed. After 10 days of the surgical procedure, the patient was asked to remove the sutures, and no changes were identified regarding the physiological parameters and blood count. Discussion: Pilomatricomas are commonly benign neoplasms arising from the germ cells of the follicular matrix. They present dermal or subdermal forms, with several cystic structures which are surrounded by keratinocytes, similar to the matrix cells of an anagen hair follicle, more keratinized and firmer areas, corroborating the results of the present report. In the ultrasound examination, the presence of intra-abdominal metastases was not identified, which is consistent with the literature, since in this type of neoplasm it is not common to identify foci of intra-abdominal and thoracic metastases. In the present report, immunohistochemistry was not used, even though it is used to differentiate follicular neoplasms from pilomatricomas. However, histopathological examination is considered the best method for the definitive diagnosis of pilomatricomas in dogs. It was concluded that the surgical treatment through excisional biopsy, with safety margins of 2 cm, was effective as a therapeutic method in the case of benign pilomatricoma, and the definitive diagnosis must be made through histopathological examination.

O cimento ósseo de polimetilmetacrilato é considerado um material padrão como carreador de antibiótico em cirurgias ortopédicas. A energia ultrassônica é um método capaz de gerar efeitos biológicos por mecanismos térmicos e não térmicos. Este estudo teve como objetivo analisar a dispersão de azul de metileno em pérolas de polimetilmetacrilato combinada com a exposição em campo acústico gerado por ultrassom não térmico. Foram utilizados 49 corpos-de-prova, cada um composto por uma pérola de polimetilmetacrilato (0,6 mm de diâmetro) dopada com azul de metileno e depositada em amostra de gelatina. Quarenta espécimes foram divididos em quatro grupos de 10 amostras com base nas intensidades de ultrassom (Grupo 1: 1,0 W/cm2; Grupo 2: 1,5 W/cm2) e profundidade (A - 2 cm; B - 3 cm) dos grânulos de polimetilmetacrilato na amostra de gelatina. Os outros nove espécimes constituíram o grupo controle. O grupo controle diferiu estatisticamente dos outros grupos. Todos os grupos irradiados com ultrassom apresentaram diferenças significativas, exceto os Grupos 2A e 2B. A dispersão de azul de metileno na gelatina entre os grupos foi: 1A> 1B; 2A> 1A; 2B> 1A; 2A> 1B; 2B> 1B. Ultrassom de baixa intensidade permitiu maior dispersão de azul de metileno com polimetilmetacrilato posicionado mais superficialmente, e não ocorreu influência da profundidade da pérola com ultrassom de alta intensidade.


Polymethylmethacrylate bone cement is a standard material used as antibiotic carrier in the orthopedic surgery. The ultrasonic energy method is capable of triggering biological effects based on both thermal and non-thermal mechanisms. The aim of the current study is to analyze methylene blue dispersion in polymethylmethacrylate beads, in association with the acoustic field generated by non-thermal ultrasound. Forty-nine specimens were used, and each specimen comprised one polymethylmethacrylate bead (0.6-mm diameter) doped with methylene blue and deposited in gelatin sample. Forty test specimens were divided into four groups comprising 10 samples, each, based on different ultrasound intensities (Group 1: 1.0 W/cm2; Group 2: 1.5 W/cm2) and polymethylmethacrylate bead depths (A - 2 cm; B - 3 cm) in gelatin sample. The control group comprised other nine specimens and statistically differed from the other groups. All groups irradiated with ultrasound have shown statistically significant differences in methylene blue dispersion, except for Groups 2A and 2B. Methylene blue dispersion in gelatin among groups was 1A> 1B; 2A> 1A; 2B> 1A; 2A> 1B; and 2B> 1B. Low-intensity ultrasound enabled the highest methylene blue dispersion when polymethylmethacrylate bead was positioned superficial; bead depth associated with high-intensity ultrasound did not influence methylene blue dispersion.

Purpose: To evaluate the effects of the intra-articular application of hyaluronic acid associated with triamcinolone acetonide, and ozone gas in the treatment of induced osteoarthritis in rabbit’s stifles.Methods: Twenty-one Norfolk rabbits were submitted to cranial cruciate ligament transection of the left stifle. After six weeks of the surgery, the rabbits were randomized assigned into three groups: G1 (control) – saline solution (0.9%); G2 – hyaluronic acid associated with triamcinolone; G3 – ozone gas, submitted to three intra-articular applications every seven days. Results: Significant differences occurred: osteophytes at medial femoral condyle (G2 > G1, G2 > G3) on radiography exam; thickening of the medial condyle (G1 > G3, G2 > G3) on ultrasound exam; osteophytes at lateral tibial condyle (G2 > G1, G2 > G3), and medial femoral condyle (G1 > G2, G3 > G1) on computed tomography. Histologically, mean values of chondrocytes in the femur and tibia in G3 and G2 were statistically lower. Conclusions: The intra-articular injection of hyaluronic acid associated with triamcinolone accentuated degenerative joint disease by imaging and macroscopic evaluations, and by histological findings, this treatment and the ozone gas treatment showed similar effects and were inferior to the saline solution (0.9%).

Background: Canine transmissible venereal tumor (TVT) is a tumor of round cells. Vincristine sulfate is the most effective for TVT. Alternatively, hemotherapy is an alternative therapy that consists of the administration of autologous blood and the positive effects are associated with an immunomodulatory effect. Since chemotherapy has some collateral effects, it is necessary to study another treatment with minimal side effects. In this context, this report case aimed to describe the use of autohemotherapy associated with vincristine sulfate for treating a transmissible venereal tumor in the vulvar mucosa of 7 adult bitches, being the first case report in Mozambique, Africa. Case: Seven adult bitches, median size, were referred to the School Veterinary Hospital, School of Veterinary, Eduardo Mondlane University, Maputo, Mozambique, Africa, with a diagnosis of TVT in the vulvar mucosa. All bitches were treated weekly with autohemotherapy and vincristine sulfate for 21 days. The parameters assessed included clinical and TVT macroscopic examination, complete blood count, serum biochemical examination and urinalysis, and were evaluated 60-min before each treatment. No clinical side effects were identified during the treatments. Color, appearance and tumor size were changed during the treatment period, and all bitches showed complete remission of the tumor 21 days after the beginning of treatment or after the third therapeutic session. The values of the complete blood count, serum biochemical and urinalysis did not demonstrate significant variations throughout the evaluated time-points. The TVT cytopathological classification was lymphocytic (42.9 %), plasmacytic (28.6 %) and lymphoplasmacytic (28.6 %). Discussion: The aims of this report were to describe the combination of autohemotherapy and vincristine sulfate for treating the transmissible venereal tumor located in the vulvar mucosa of adult bitches, through clinical and laboratory evaluation, and was not...

Background: Whole-Body Vibration (WBV) consists of mechanical vibration stimuli produced that propagate throughout the body by increasing the gravitational load. The WBV can increase muscle mass in dogs with muscular atrophy. As Whole-body vibration (WBV) can be used as exercise modality with no impact on the joints, the present study aimed to evaluate the effects of single session of WBV in hematobiochemical and hemogasometric parameters in adult and elderly healthy dogs. Materials, Methods & Results: Fourteen clinically healthy, neutered crossbreed male dogs, non-athlete were selected. The dogs were divided into two groups of seven dogs, according to the age group: Group I - adult dogs (GI): age between 12.0 and 84.0 months old; Group II - elderly dogs (GII): age above 84.0 months old. All dogs were submitted to a single session WBV by using a vibrating platform that delivered a vortex wave circulation as mechanical vibration. The WBV protocol used was 30 Hz frequency (3.10 mm peak displacement; 11.16 m/s2 peak acceleration; 0.29 m/s velocity), then 50 Hz (3.98 mm peak displacement; 39.75 m/s2 peak acceleration; 0.62 m/s velocity), and lastly 30 Hz (3.10 mm peak displacement; 11.16 m/s2 peak acceleration; 0.29 m/s velocity) for 5-min between de frequencies. The hematobiochemical and hemagasometric parameters were evaluated at 1-min before the WBV session (1PRE), 1-min after the WBV session (1POST), 120-min (120POST) and 24 h after the WBV session (24hPOST). The dogs accepted the vibration stimulus quite well, however, elderly dogs weighing above 30 kg were more likely to sit down with increased frequency from 30 to 50 Hz. No variations of food and water intakes and gastrointestinal changes were observed after the WBV session. Hemoglobin values showed significant decrease (P = 0.0312) between 1PRE and 1POST in elderly dogs. A significant decrease (P = 0.0453) was observed in alanine aminotransferase values between 120POST...

Background: A great variety of natural products have been evaluated for the skin wound healing due to anti-inflammatory,antioxidant and antibacterial activities, and procollagen synthesis, of which may be mentioned the honey and propolis. Inturn, low-level laser therapy (LLLT) is considered an important tool in the treatment of skin wounds, because of ability toraise the ATP production, to stimulate the microcirculation, and formation of new blood vessels. Therefore, this study aimedto assess the influence of LLLT, alone or combined with natural products, in the healing of excisional skin wounds in rats.Materials, Methods & Results: One hundred twenty-six male Wistar rats, aged 14 weeks, were randomly divided intoseven groups (n = 18 per group) according to wound treatments: G1 (negative control): 0.9% saline solution; G2 (positive control): allantoin + zinc oxide ointment; G3: LLLT; G4: mixture of honey + 5% propolis hydroalcoholic solution;G5: LLLT + mixture of honey + hydroalcoholic solution of 5% propolis; G6: LLLT + honey in natura; G7: LLLT + 5%propolis hydroalcoholic solution. Six rats from each group were euthanized on the 7th, 14th, and 21th postoperative days.Macroscopic and histological evaluations of wound healing were performed. A decrease in wound area occurred in allgroups, but in general G4 had the higher reduction and G1 and G3 had the lower reductions. These findings correspondedto the percentage of wound contraction, since the largest contraction was G4 and the lowest contractions were G1 andG3. Histological analysis showed no significant difference among groups...

Background: Whole-Body Vibration (WBV) is an oscillatory mechanical stimulus spreading throughout the body and considered a type of physical exercise because of the activation of the cardiovascular, musculoskeletal, and neuroendocrine systems. It is a physical exercise modality since it promotes cardiovascular resistance, increase in muscular strength and neurosensitivity, and motor coordination improvement. For use of WBV as an exercise modality for dogs, it is necessary to evaluate the Dopplerfluxometry parameters of the common carotid artery in healthy dogs in order to perform a safe protocol without inducing any cerebral alteration. This study aimed to evaluate the acute effects of WBV on systolic peak velocity (SPV), resistivity (RI), and pulsatility index (PI) of the both common carotid artery among adults and elderly non-athletes healthy dog. Materials, Methods & Results: Fourteen clinically healthy, neutered crossbreed male dogs, non-athlete were divided into two groups of seven dogs, according to the age group: Group 1 (G1)- Adult dogs: age between 12 and 84 months; Group 2 (G2)- Elderly dogs: aged over 84 months. All dogs were submitted to sessions of WBV using the protocol of 30 Hz for 5 min, followed by an increase to 50 Hz for 5 more min and ending with 5 min at 30 Hz, without rest between the variation of the vibration frequency. The systolic peak velocity (SPV), resistivity (RI), and pulsatility index (PI) of the common carotid artery were assessed in two time-points: 5 min before the WBV sessions (5PRE) and 1 min after the WBV (1POS). No significant variations in the SPS, RI, and PI of both common carotid artery of the G1 and G2 were identified. The anatomic reference for the left and right common carotid artery was the right and left extern jugulars veins, which were...

Background: Acute spinal traumas can lead to irreversible damage associated with vascular and inflammatory changes in neural tissue. Since spine and spinal cord traumas have an unfavorable prognosis in small animals, and reports of the use of Steinmann pins and polymethylmethacrylate repair of lumbar vertebra fracture-luxation in puppies are rare in the literature, the present paper aimed to report the surgical treatment of transversal fracture through the body of the fourth lumbar vertebra, with dorsocranial displacement of the caudal fragment by using Steinmann pins and polymethylmethacrylate in a 7-month-old Labrador Retriever male dog. Case: A 7-month-old intact male Labrador Retriever dog, weighing 24.0 kg was attended at School Veterinary Hospital with a history of hit by car and paraplegia of the hind limbs. On neurological examination was observed no proprioception and no deep pain sensitivity on the both pelvic limbs. The lumbar spinal palpation showed intense pain, and the motor function and patellar reflexes were reduced. The values of haematological and biochemical analysis remained within the reference values for the species. Radiographs revealed a transversal fracture through the body of the fourth lumbar vertebra, with dorsocranial displacement of the caudal fragment, and was decided to perform a surgical treatment by open reduction and internal fixation of the fracture. The dog was positioned in ventral recumbency for surgery, and a dorsal midline incision was made from the second lumbar vertebra to the sixth lumbar vertebra. Two crossed 1.5 mm Kirschner wires were placed through the caudal articular facets of the fourth lumbar vertebra to provide initial stability...

Background: Acute spinal traumas can lead to irreversible damage associated with vascular and inflammatory changes in neural tissue. Since spine and spinal cord traumas have an unfavorable prognosis in small animals, and reports of the use of Steinmann pins and polymethylmethacrylate repair of lumbar vertebra fracture-luxation in puppies are rare in the literature, the present paper aimed to report the surgical treatment of transversal fracture through the body of the fourth lumbar vertebra, with dorsocranial displacement of the caudal fragment by using Steinmann pins and polymethylmethacrylate in a 7-month-old Labrador Retriever male dog. Case: A 7-month-old intact male Labrador Retriever dog, weighing 24.0 kg was attended at School Veterinary Hospital with a history of hit by car and paraplegia of the hind limbs. On neurological examination was observed no proprioception and no deep pain sensitivity on the both pelvic limbs. The lumbar spinal palpation showed intense pain, and the motor function and patellar reflexes were reduced. The values of haematological and biochemical analysis remained within the reference values for the species. Radiographs revealed a transversal fracture through the body of the fourth lumbar vertebra, with dorsocranial displacement of the caudal fragment, and was decided to perform a surgical treatment by open reduction and internal fixation of the fracture. The dog was positioned in ventral recumbency for surgery, and a dorsal midline incision was made from the second lumbar vertebra to the sixth lumbar vertebra. Two crossed 1.5 mm Kirschner wires were placed through the caudal articular facets of the fourth lumbar vertebra to provide initial stability...(AU)

Background: A great variety of natural products have been evaluated for the skin wound healing due to anti-inflammatory,antioxidant and antibacterial activities, and procollagen synthesis, of which may be mentioned the honey and propolis. Inturn, low-level laser therapy (LLLT) is considered an important tool in the treatment of skin wounds, because of ability toraise the ATP production, to stimulate the microcirculation, and formation of new blood vessels. Therefore, this study aimedto assess the influence of LLLT, alone or combined with natural products, in the healing of excisional skin wounds in rats.Materials, Methods & Results: One hundred twenty-six male Wistar rats, aged 14 weeks, were randomly divided intoseven groups (n = 18 per group) according to wound treatments: G1 (negative control): 0.9% saline solution; G2 (positive control): allantoin + zinc oxide ointment; G3: LLLT; G4: mixture of honey + 5% propolis hydroalcoholic solution;G5: LLLT + mixture of honey + hydroalcoholic solution of 5% propolis; G6: LLLT + honey in natura; G7: LLLT + 5%propolis hydroalcoholic solution. Six rats from each group were euthanized on the 7th, 14th, and 21th postoperative days.Macroscopic and histological evaluations of wound healing were performed. A decrease in wound area occurred in allgroups, but in general G4 had the higher reduction and G1 and G3 had the lower reductions. These findings correspondedto the percentage of wound contraction, since the largest contraction was G4 and the lowest contractions were G1 andG3. Histological analysis showed no significant difference among groups...(AU)

Background: Pharmacodermia is a drug reaction that manifests itself on the skin and mucous membranes. The main drugsthat cause pharmacodermia are β-lactam antibiotics. It has a rare occurrence in dogs and may present different clinical signs.Ozone therapy is used to treat various conditions, such as infections and inflammatory diseases. This therapy acts throughoxidative stress generating a positive inflammatory response to the body and stimulating the formation of granulation tissue andangiogenesis. Since pharmacodermia is rare in dogs and reports of ozonized sunflower oil and ozone for treat pharmacodermiais are rare in the literature, this paper aimed to report the use of ozonized sunflower oil in the treatment of pharmacodermiain a young female Rottweiler dog assisted and treated at a private veterinary clinic in Garanhuns, Pernambuco, Brazil.Case: A 2-year-old Rottweiler female, weighting 53.3 kg was attended at a private veterinary clinic in Garanhuns (Pernambuco- PE) with a history of dystocia. The dog was submitted to ovary-hysterectomy under general anesthesia. After anesthesiarecovery was prescribed omeprazol (1 mg/kg, orally (P.O) SID for 10 days), cephalexin (20 mg/kg, P.O. BID for 10 days),tramadol hydrochloride (4 mg/kg, P.O. BID for seven days), carprofen (4.4 mg/kg, P.O. SID for three days), and the use ofElizabethan collar. Furthermore, for topical treatment was described chlorhexidine digluconate (0.2%) and ointment of allantoin and zinc oxide, SID, for 10 days. Seven days after the surgical procedure, the owner’s dog reported by a telephone callthe appearance of wounds in the dorsal region of the dog. Ten days after surgery, the dog returned to the veterinary clinic forstitches removal and wounds evaluation. During the physical examination, observed the presence of two cutaneous wounds,one located in the cervicothoracic region and the other wound...

Background: Coatis (Nasua nasua) have easy interaction with man, besides being sociable and curious animals. Theproximity to urbanized areas encourages them to intake food from anthropogenic sources, and it can change their eatinghabits and make them prone to obesity. The body condition evaluates the animals’ energetic status and measures variations in their body fat reserves. There are direct-invasive methods and indirect methods that rely on size and body massto evaluate the body condition, like body condition score and body mass index. Thus, the aim of the present study was toassess different methods to determine the body condition of wild coatis (Nasua nasua) living in urban areas.Materials, Methods & Results: Sixteen wild coatis (Nasua nasua), nine females and seven males, were captured at Facultyof Veterinary Medicine and Animal Science (FMVZ) of São Paulo State University, Botucatu, in pitfalls. The animals wereanesthetized with ketamine and midazolam and subjected to biometric evaluation after physical exams proved normal. Thefollowing variables were analyzed: body weight, body condition score (BCS) based on the five-point scale for dogs, thoracicand abdominal circumference, height at the withers, spine length and distance from the patella to the calcaneus. Two bodymass index (BMI) were calculated from these data, one was based on dogs (BMI1) and another one on cats (BMI2), as well asthe body fat percentage (%BF). Results showed that 25% of the assessed coatis were overweight. Body weight, thoracic andabdominal circumference, height at the withers, spine length and distance from the patella to the calcaneus were significantlyhigher in males than in females and the other assessed parameters did not present differences between sexes. The correlationbetween fat percentage and body weight was significant, and that between fat percentage and BCS was not. There was closer correlation...

Background: In Veterinary Medicine, there are several methods for early and accurate assessment of blood flow dynamics. The Dopplerfluxometry can access the peak systolic velocity, mean velocity and end diastolic velocity, including Resistive Index and Pulsatility Index. Normal values of Dopplerfluxometry in healthy dogs allow the identification of vascular abnormalities and authors’ knowledge there are no reference regarding the values of Dopplerfluxometry of the femoral artery in healthy dogs. The aim of the study was to assess the femoral Dopplerfluxometry of adult healthy dogs by Resistive Index, Pulsatility Index, systolic and diastolic velocities, and femoral artery diameter.Materials, Methods & Results: Eighteen healthy intact beagle dogs, male and female, aging from 2 to 4 years old (mean ± SD: mean 3 ± 0.8 years), weighing from 10.1-17.9 kg [22.3-39.5 lb] [mean ± SD: 14.3 ± 2.7 kg (31.5 ± 5.96 lb)] were used. The dogs underwent to physical examination, complete blood cell count, serum biochemistry examination urinalysis, and radiographs examination, muscular and cardiac evaluation. Females had to be in anestrous. All dogs were submitted to right femoral artery Dopplerfluxometry. The dogs were positioned in dorsal recumbency by one person without any chemical restraint. A high definition ultrasound device equipped with a 3 - 13 MHz multi-frequency linear transducer was used. The right femoral artery was identified with the transducer positioned transversely on the right triangle femoral area. Peak systolic velocity, end-diastolic velocity was measured. The Resistivity Index and Pulsatility Index were calculated automatically by the ultrasound machine software. Three measurements were obtained with the Doppler spectrum. The values of peak systolic velocity, end-diastolic velocity, Resistivity Index, Pulsatility Index and femoral artery diameter were expressed as Mean ± Standard Deviation (SD).[...]
