OBJECTIVE We employ a nasal tip finite element model (FEM) to evaluate contributions of two of the three major tip support mechanisms: attachments between the upper and lower lateral cartilages and attachment of the medial crura to the caudal septum. STUDY DESIGN The nasal tip FEM computed stress distribution and strain energy density (SED) during nasal tip compression. We examined the impact...

Fractures of the caudal portion of the mandible and temporomandibular joint (TMJ) fracture-luxation can be challenging to treat with direct fixation methods. This paper describes a simple technique for the indirect treatment of caudal mandibular fracture and TMJ fracture-luxation using a subcutaneous loop of nylon leader line tunnelled around the maxilla, incisive and nasal bones, and under the...

     Urethralduplication is a rare condition occurs as a congenital malformation either independently or in the setting of other congenital malformations such as caudal duplication syndrome. Its prevalence becomes even rarer if it manifests as two side-by-side tracts in coronal plan.Nonetheless, we introduce a unique presentation of complete coronal urethral duplication accompanied by astoundin...

This paper presents a mechanical actuator for the biomimetic propulsion of swimming devices and the experimental study of the effect of the caudal fin elasticity on the overall performance. The design of the proposed drive allows the DC motor to operate at constant speed, so all the power of the motor is spent only for the motion of the caudal fin. A prototype of the actuator, in which the caud...

AIM To compare the results of ultrasound and fluoroscopy guided caudal epidural steroid injections in postlaminectomy patients. MATERIAL AND METHODS Thirty postlaminectomy patients were randomly divided into two groups, Group I (n=15) received ultrasound-guided and Group II (n=15) received fluoroscopy-guided caudal epidural local anesthetic and steroid injection. Time of block for each patien...

OBJECTIVE To evaluate the effect of tibial plateau leveling on joint motion in canine stifle joints in which the cranial cruciate ligament (CCL) had been severed. STUDY DESIGN In vitro cadaver study. ANIMALS Six canine cadaver hind legs. METHODS Radiographs of the stifle joints were made to evaluate the tibial plateau angle with respect to the long axis of the tibia. The specimens were mo...

The spinal projections of afferent fibers innervating the facet joints between caudal vertebrae were examined by the use of anterograde transport of wheat germ agglutinin-horseradish peroxidase (WGA-HRP). Experiments were performed on 5 adult cats in which spinal dorsal roots below the 2nd sacral segment (S2) on the right side were cut. Injections of WGA-HRP into the caudal facet joints gave ri...

Correspondence Adjuncts to caudal blockade in children Editor—We read with great interest the editorial by Lön-nqvist 1 regarding caudal additives. The author gives an excellent description of the chronological development of caudal adjuncts. Nevertheless, we were somewhat surprised by his affirmations regarding caudal neostigmine. The author claims that two studies are proof enough to show tha...

Previous studies have shown that microinjection of atrial natriuretic peptide into the caudal nucleus tractus solitarii produces significant increases in local neuronal firing rate associated with reductions in arterial pressure in anesthetized Wistar rats. Single units excited by microinjection of atrial natriuretic peptide into the caudal nucleus tractus solitarii were also excited by activat...

BACKGROUND Caudal regression syndrome is a rare, neural tube defect characterized by an abnormal development of the caudal aspect of the vertebral column and the spinal cord., It results in neurological deficits ranging from bladder and bowel involvement to severe sensory and motor deficits in the lower limbs. Maternal diabetes, genetic factors and some teratogens have been shown to be associat...
