ResumoAs Doenças do Trato Urinário Inferior Felino (DTUIF) são frequentes na rotina clínica desta espécie, é decorrente de diversos processos mórbidos caracterizados por hematúria, disúria, polaciúria, estrangúria, periúria e obstrução uretral, que afetam principalmente felinos sedentários, de vivência intradomiciliar e com baixa ingestão de água. Com o objetivo de verificar as principais alterações clínicas, laboratoriais e ultrassonográficas nos casos de DTUIF, foram examinados 26 felinos no Hospital Veterinário da UFMT, sendo, 16 com DTUIF e dez hígidos, notando-se que todos os animais doentes apresentaram azotemia, valor médio da concentração sérica de cálcio total diminuído e elevação na concentração sérica de fósforo. Crescimento bacteriano foi observado em um terço dos casos, sendo três possivelmente decorrentes de cateterização vesical, já que eram casos recidivantes. Os achados ultrassonográficos foram compatíveis com quadros de obstrução, tais como: distensão acentuada da vesícula urinária e debris em suspensão, dilatação de ureteres e uretra. Palavras-chave: Doença do trato urinário inferior, felinos, azotemia, ultrassonografia AbstractThe Lower Urinary Tract Disease Feline (FLUTD) are frequent in clinical routine of this species is due to various disease processes characterized by hematuria, dysuria, urinary frequency, strangury, periuria and urethral obstruction, affecting mainly sedentary cats, living in the home and with low intake of water. In order to check the main clinical, laboratory and ultrasound in cases of FLUTD, 26 cats were available at the Veterinary Hospital of UFMT being 16 with FLUTD and ten healthy, noting that all the sick animals had azotemia, average of serum total calcium decreased and elevation in serum phosphorus. Bacterial growth observed in one third of cases, three possibly due to bladder catheterization, as were recurrent cases. The sonographic findings were compatible with frames of obstruction, such as severe distension of the urinary bladder and debris in suspension, dilated ureters and urethra.

Objectives To determine the concentrations of total protein (TP), tissue inhibitor of matrix metalloproteinase‐1 (TIMP‐1) and hyaluronic acid (HA) in amniotic membranes (AMs) harvested from placentas of bitches of different ages and cryopreserved for different time points. The outcomes of complicated corneal defects of dogs repaired with AMs stored for the same time points were also evaluated. Procedures Ten cryopreserved canine AMs were stored for short term (2–50 days), middle term (92–210 days), or long term (256–357 days). TP was quantified by Bradford’s test, whereas TIMP‐1 and HA were quantified by ELISA. Twenty‐one dogs that had an AM transplantation to restore deep or perforating corneal wounds were selected. Results TIMP‐1 levels were lower in AMs cryopreserved for middle term (p = .02) and long term (p = .0009), when compared to AMs stored for short term. TP (p = .39) and HA (p = .18) concentrations in AMs did not differ among the storage time. TIMP‐1 concentration in AMs correlated with storage time (R = −.65, p < .0001), while TP (R = −.33, p = .07) and HA concentrations did not (R = −.15, p = .41). The age of donors did not correlate with the components evaluated in the AMs. Corneal defects repaired with AMs stored for short term healed sooner than the ones repaired with AMs stored for middle (p < .01) and long term (p = .02). Additionally, TIMP‐1 levels in AMs correlated negatively with the epithelization time (R = −.62, p = .002). Graft opacity was severe in 55% of cases. However, the HA levels in AMs correlated negatively with the opacification score (R = −.47, p = .03). Vision was observed in more patients who presented deep ulcers and descemetoceles, than in the ones with perforations (p = .004). Conclusions TIMP‐1 concentration in canine AMs significantly decreased over a year storage time, while TP and HA concentrations did not change during the same period. The age of donors did not correlate with the components evaluated in the AMs. Complicated corneal defects repaired with AMs cryopreserved for short term healed sooner and tended to be less opaque; however, satisfactory to optimal outcomes were achieved even in the eyes repaired with AMs stored for up to a year.

Rapid prototyping (RP) is an innovative technology that allows one to obtain a prototype of a mold quickly and accurately from a virtual model. This study aimed to establish the use of photogrammetry and 3D prototyping for the production of bone biomodels of the canine species for training in orthopedic techniques in veterinary medicine. Virtual bio-modelling was performed by the photogrammetry technique with commercial anatomical pieces, and physical biomodelling was performed by 3D printing. Osteotomies were performed on the biomodels that served as platforms for osteosynthesis of the femur and ileum, and the final product was not associated with a risk of biological contamination, was able to support special orthopedic materials, and was used for training and surgical planning. We concluded that the use of photogrammetry and RP for the production of bone biomodels of the canine species enabled techniques for fracture reduction to be performed with the use of special instruments, enabling training in the area of veterinary orthopedics in an economically viable manner with an alternative to experimental animals.

Abstract. Dacryops is a closed cyst that develops on the palpebral lobe of the lacrimal gland, manifesting in the region of the external canthus. Its slow and insidious growth causes mechanical and aesthetic problems that do not regress spontaneously. Treatment involves excision of the cyst while sparing the adjacent glandular tissues. In cases associated with hypolacrimation, marsupialization of the cyst is indicated. To obtain a reduction of the cyst to an aesthetically acceptable level in cases of simple dacryops, the authors suggest argon laser therapy, which avoids the risks related to surgery and general anesthesia and eliminates the need for hospitalization. Two patients with simple dacryops were treated with blue-green argon laser under local anesthesia. At the end of follow-up, the cysts had been clinically reduced in volume and were not visible by external examination. In cases of simple dacryops, laser therapy is suitable for the reduction of the cyst. Photocoagulation treatment is not advisable in cases that are complicated by fistulas or where the clinical presentation is atypical. [Ophthalmic Surg Lasers 1997;28:690-692.]
