BACKGROUND AND OBJECTIVES: Body lateropulsion with falling to one side is a well-known clinical feature of stroke in the posterior circulation. Body lateropulsion as an isolated or predominant manifestation of a pontine stroke has not previously been reported. To elucidate the possible mechanisms of patients presenting with body lateropulsion as an isolated or predominant symptom of isolated pontine infarction. MATERIALS AND METHOD: Between May 2004 and February 2006, out of 134 admitted patients with an isolated pontine stroke we identified 8 consecutive patients (6.0%) in the Keimyung University Stroke Registry who had body lateropulsion as the main presenting symptom. RESULTS: All lesions were localized to the paramedian tegmentum just ventral to the 4th ventricle. All except 1showed a uniform pattern of body lateropulsion, in which the direction of falling was away from the side of infarct. In 2 patients, body lateropulsion was the sole clinical manifestation, whereas the other patients had other neurological signs. All but 1 had contraversive tilting of the subjective visual vertical (SVV). In all cases, the direction of SVV tilt corresponded to the direction of body lateropulsion. The mean net tilt angle was 6.1 CONCLUSION: Based on the known anatomy of ascending vestibular pathways, the SVV tilting, and MRI findings, body lateropulsion probably results from damage to the graviceptive pathway ascending through paramedian pontine tegmentum.

Cerebral venous infarction is associated with a wide variety of clinical symptoms and signs, which may often delay appropriate diagnosis. Unilateral vestibular deficit as a presenting sign of cerebral venous infarction has rarely been reported. We report a patient with cerebral venous infarction who had severe prolonged vertigo, vomiting, occipital headache, positive head thrust testing, and unilateral caloric weakness as main clinical features. Although the patient had occipital headache, overall symptoms and signs closely mimicked those of acute peripheral vestibulopathy.

Vestibular neuritis (VN) is an idiopathic peripheral vestibular syndrome characterized by acute isolated prolonged vertigo. In most cases, it results from inflammation of the vestibular nerve presumably of viral origin. There has been no previous report of VN associated with a vascular cause. We here report a patient with VN of vascular origin who presented with acute onset of prolonged isolated vertigo, a unilateral decreased caloric response, and simultaneously with acute infarcts on brain MRI that were unrelated to patient's vertigo.

The use of a pneumatic tourniquet is potentially associated with injury to underlying muscles, vessels, and nerves if excessive pressure occurs beneath the toumiquet. In order to minimize the risk of soft tissue injury, the lowest tourniquet pressure that maintains a bloodless operative field should be used. A clinical study was undertaken to evaluate the pneumatic tourniquet setting required for adequate hemostasis in upper extremity surgery. From March to September in 1984, the subcutaneous soft tissue pressure of the 20 upper extremities beneath a pneumatic toumiquet in the arm were measured directly and the following results were obtained. 1. The underlying subcutaneous soft tissue pressure was not affected by adult, age, arm circumference, and blood pressure of normal range. 2. The underlying subcutaneous soft tissue pressure showed direct correlation with the tourniquet pressure respectively. 3. A tourniquet preasure of more than 250 mmHg was not rarely required in a normotensive individual.

Reconstruction of soft tissue defect with exposure of the tendons and bone in the lower third of the leg and the heel represents a challenge to plastic surgeons. The sural artery flap is a fasciocutaneous flap supplied by the sural artery that accompanies the sural nerve and connects with a septocutaneous perforator of the peroneal artery via a suprafascial network of vessels. For the coverage of soft tissue defects, we operated on 10 patients using a distally-based sural artery flap. The sites of the soft tissue defect were the lower third of the leg in 7 cases and the heel in 3 cases. The size of flap varied from 3.5x4cm to 12x18cm. Nine of 10 flaps survived completely. One flap in which the sural nerve was preserved showed partial necrosis but healed spontaneously. Two flaps showed slightly venous congestion which disappeared after a few days. The advantages of the sural flap are a reliable blood supply, easy and quick elevation of the flap, preservation of the major artery and minimal donor site morbidity. The disadvantage of the flap is hypoesthesia at the lateral part of the foot. In conclusion, the distally-based sural artery flap can be used safely for soft tissues coverage in the lower third of the leg and the heel.
