BACKGROUND AND OBJECTIVES: Walking is an indispensable daily locomotion and requires highly organized and dynamic body balance which is maintained by visual, vestibular and proprioceptive system. This study was designed to measure the forefoot position and walking speed in normal cats. MATERIALS AND METHODS: Five normal cats were selected and trained to walk over a platform (188 cm long, 65 cm wide) of different upward and downward slope up to 15 degrees in a natural way. When a cat walks, the magnetic field generated from AC generators of two different frequencies through a coil in a cat's shoes was changed. The induced current of detecting coils under the platform was repeatedly measured. The sensitivity (minimal distance required to be separated in a different position) was 5 mm in the right and left axis, 10 mm in anterior and posterior axis. RESULTS: The mean crossing time over platform was 1.9+/-0.3 seconds. Mean walking speed was 648.2+/-76.5 mm/sec without significant differences between individuals or degrees of slope. The range of mean deviation was in between 4.4+/-48.8 mm to the right and 5.6+/-42.8 mm to the left with a different slope. There was a significant difference between 0 degree and upward 10, 15 degrees and downward 5, 15 degrees of slope but no difference between individuals. Walking distance in right-left and anterior-posterior axis were 53.1+/-10.3 and 213.1+/-79.4 mm, respectively, without a significant difference between individuals or degrees of slope. There was no change of foot position in standing 30 degrees upward or 30 dgrees downward. CONCLUSION: These results could be a baseline data for both normal and pathologic cat walking and this precise method will be also useful in clinical settings.

Mucinous adenocarcinoma is a rare malignant neoplasm that occasionally occurs in gastrointestinal tract and mammary glands. It is characterized by large amounts of extracellular epithelial mucin that contains solitary epithelial cells, cords and nests. Mucinous adenocarcinoma of the major salivary glands is extremely rare, and only 10 cases have been reported. Recently, we experienced a case of mucinous adenocarcinoma of the parotid gland treated with total parotidectomy and postoperative radiotherapy. The patient has been free of disease for 2 years after treatment. So we report the case with a brief review of literature.

The anterior process of the malleus (process of Folius) in the middle ear develops through an intramembranous ossification center that appears in the human embryo of 26.5 mm crown-rump length at a caudomedial position in relation to Meckel's cartilage. We present one case of an ossicular anomaly considered to consist of an abnormality of the anterior process and manubrium mallei (malleus handle). In this case, a thick bony bar was found extending from the neck of the malleus and abnormally developed an anterior process of the malleus to the posterior bony wall or the tympanic bone. In the anterior part, a thick bony bar was also found in the anterior bony wall connecting with the malleus neck and the anterior process of malleus, which was abnormally developed by fibrous tissue. The manubrium mallei and the umbo were not identified and the anterior process of the malleus was recognized as an abnormally developed bony fragment. On the basis of these findings, the bony bar was assumed to represent an abnormally developed mesenchyme bone (os goniale), which later developed into the anterior process of the malleus.

Septic inflammation and thrombosis of the cavernous sinus was extremely fatal in the preantibiotic era. After the introduction of antibiotics, the incidence of septic cavernous thrombophlebitis has diminished significantly. It is, however, still a serious disease accompanied by a high morbidity and mortality rate. Therefore, a high index of suspicion and aggressive initiation of treatment is of the utmost importance for the prognosis. A case of cavernous sinus thrombophlebitis and abducence nerve palsy which takes place secondary to petrositis was diagnosed by magnetic resonance imaging (MRI), and is presented here. The resolution of septic thrombus and complete recovery of sixth (abducens) nerve palsy was observed with treatment with antibiotics and steroids accompanied by tympanotomy tube placement.

Congenital esophageal stenosis is a extremely rare disease in childhood. We experienced one patient with a case of esophageal stenosis with esophageal solid food impaction. According to her history of dysphagia, cine esophagogram, pH-monitoring, and esophagoscopic findings, this esophageal stenosis was confirmed as congenital stenosis. We thus reported this case along with a relevant literature review.

A congenital nasolacrimal duct cyst is a very rare cause of respiratory distress and feeding difficulty in the newborn who is an obligate nasal breather. A case of bilateral nasolacrimal duct cysts (NLDC) without an associated congenital dacryocele was first reported in 1993. The authors present a case of a newborn with bilateral NLDC with intranasal extension causing respiratory distress, but with no evidence of dacrocystitis. Diagnostic studies included intranasal endoscopy and CT scanning of the nasolacrimal system and nose. The patient was treated by endoscopic marsupialization of the cysts. After six months of treatment, there was no evidence of recurrence.
