Management of the bulbous nasal tip with inadequate projection and drooping is challenging aesthetic plastic surgery. The bulbous nasal tip is influenced by several factors; 1) thick, non-elastic oily skin, 2) soft tissue bulkiness due to supratip fibrous fatty tissue, and 3) a wide intercrural angle or increased interdormal distance. Another common factor among caucasians, hypertrophic alar cartilage, is seen less in orientals. These variable factors can be corrected with various surgical maneuvers for proper tip projection and refined alar shape. All these procedures are performed through open rhinoplasty incision. The fibromuscular fatty tissue on the nasal tip is resected with subdermal tangential excision without violating the detmal blood supply. The proximal part of the lateral crus, dome and the part of medial crus which was isolated from the skin and nasal mucosa are replaced and plicated in midline in the role of a new columellar strut and skeletal support. If more skeletal supports are desired, the new columellar is reinforced with a silicone strut and conchal cartilage onlay grafts are applied. And for lengthening of the columella, a V-Y advancement incision on the columellar base with open rhinoplasty is applied. The pressure splint on the upper third of the columella and nasal tip is applied on the 7th postoperative day and maintained for two months. All procedures are focused on the preservation of catilaginous integrity and in providing skeletal support. We performed nasal tip plasty on the bulbous nasal tip and its simple technique and predictability resulted in improved nasal tip projection and contour.

Journal of Korean Society of Spine Surgery 2004;11(1):61-65
A complete fracture dislocation at the cervicothoracic junction is rare and accompanied by severe spinal cord injury. This region is difficult to image with plain radiography, and to immobilize with external orthosis due to the biomechanical forces exerted in this transitional portion of the spinal column. We experienced a rare case in 52-year-old male victim of a car accident. He sustained paraplegia, and complained of dyspnea and neck pain of 10 days duration at another hospital. The delayed clinical rediagnosis was a C6 and 7 spinous process fracture and a cervicothoracic fracture dislocation, with complete transection of spinal cord, which was based on a clinical examination, simple radiography, CT and MRI. Skeletal traction was immediately applied, followed by a posterior pedicle screw to stabilize the spine and secure the grafts. Rehabilitation was initiated and the dysphagia and dyspnea, due to aspiration pneumonia, were improved, but no neurologic recovery was made after the 1st postoperative year.

Cutaneous metastasis from renal cell carcinoma is not unusual, occurring in 3 to 7%, although it may be overlooked. We report a case of metastatic renal cell carcinoma in a 74-year-old man who was presented with a 1.5 x 1.5 x 0.5 cm-sized nodule on the right zygoma for 3 months. A skin biopsy demonstrated the typical clear cell adenocarcinoma with PAS(+) granules in the cytoplasm and honeycombed or glandular configuration, compatible with metastatic renal cell carcinoma. Kidney ultrasonogram and abdomina1 CT scanning showed a large cystic mass on the upper pole of the left kidney. Furthermore radiologic studies revealed multiple metastatic lesions in the lung, liver and brain. He died 4 months later.

Verrucous carcinoma of the oral cavity is a rare tumor representing 4.5-9.0% of oral squamous tumors. Involvement of the lip is less common within the oral cavity. It presents as a slowly enlarging, exophytic warty growth with extensive local invasion, though well-differentiated and rarely metastaticl. We herein repart a case of verrucous carcinoma on the lower lip in a 31-year-old man.

BACKGROUND: We conducted this study to verify whether a mechanical ventilator is adequate for cardiopulmonary resuscitation (CPR). METHODS: A self-inflating bag resuscitator and a mechanical ventilator were used to test two experimental models: Model 1 (CPR manikin without chest compression) and Model 2 (CPR manikin with chest compression). Model 2 was divided into three subgroups according to ventilator pressure limits (P(limit)). The self-inflating bag resuscitator was set with a ventilation rate of 10 breaths/min with the volume-marked bag-valve procedure. The mode of the mechanical ventilator was set as follows: volume-controlled mandatory ventilation of tidal volume (Vt) 600 mL, an inspiration time of 1.2 seconds, a constant flow pattern, a ventilation rate of 10 breaths/minute, a positive end expiratory pressure of 3 cmH2O and a maximum trigger limit. Peak airway pressure (P(peak)) and Vt were measured by a flow analyzer. Ventilation adequacy was determined at a Vt range of 400-600 mL with a P(peak) of < or = 50 cmH2O. RESULTS: In Model 1, Vt and P(peak) were in the appropriate range in the ventilation equipments. In Model 2, for the self-inflating bag resuscitator, the adequate Vt and P(peak) levels were 17%, and the P(peak) adequacy was 20% and the Vt was 65%. For the mechanical ventilator, the adequate Vt and P(peak) levels were 85%; the P(peak) adequacy was 85%; and the Vt adequacy was 100% at 60 cmH2O of P(limit). CONCLUSIONS: In a manikin model, a mechanical ventilator was superior to self-inflating bag resuscitator for maintaining adequate ventilation during chest compression.

The diagnosis of a Battered Child Syndrome is made by the pediatrician, surgeon and the radiologist because almost parents deny the diagnosis or refuse to answer the doctor's questions. The imaging modalities play a key role in the investigation and documentation of the battered child syndrome, because of the high frequency of the typical skeletal lesion. Although physical abuse is denied by parents, the recognition of this entity is possible by the primary diagnostic imaging study in the suspected child abuse. The imaging studies are either a bone scan and x-ray series or a complete radiolographic skeletal survey by X-ray series. In an expected intracranial injury, a CT scan of the head is mandatory We experienced a case of Battered Child Syndrome in a 6 month-old male infant who had subdural hemorrhage and fractures of skull and ribs in different stages of healing and repair. The brief review of the literature was made.

Eosinophilia-myalgia syndrome(EMS) is a systemic illness that occurred as an epidemic by ingestion of over-the counter L-tryptophan preparation in the United States in October 1989. We report a Korean case of EMS not associated with the ingestion of either L-tryptophan or other nutritional supplements such as lysine and niacin.

Idiopathic atrophoderma of Pasini and Pierini(IAPP) is an uncommon condition of unknown etiology and typically affects persons in the second and third decades of life. IAPP consists of asymptomatic grey to brown depressed lesions with "cliff drop" borders, which are usually bilateral and located on the trunk. A 40-year-old woman visited our department because of unilateral atrophic lesions on the abdomen, right arm, and posterior aspect of right thigh for 20 years. Laboratory evaluations were normal and histologic examination revealed significantly decreased thickness in dermis. We report an unusual case of idiopathic atrophoderma of Pasini and Pierini presenting unilateral distribution.
