Canalith repositioning maneuver is effective to treat benign paroxysmal positional vertigo(BPPV). This case showed complicated form of the BPPV such as changes of canalolithiasis to cupulolithiasis, involvement of one canal to two canals and from unilateral to bilateral involvement during the reposition maneuver. This patient was diagnosed as left lateral canalolithiasis at first. After left barbecue maneuver, the type was changed to the right posterior cupulolithiasis. Semont maneuver was performed and then the type of BPPV was changed to combined type with right posterior canalolithiasis and left lateral canalolithiasis. We performed left barbecue maneuver and right Epley maneuver. Then the type of BPPV was changed to left lateral cupulolithiasis. After Brandt-Daroff maneuver and left barbecue maneuver, nystagmus and dizziness disappeared finally.

Progressive zosteriform macular pigmented lesion(PZMPL) is a chronic pigmentary dermatosis similar to progressive cribriform and zosteriform hyperpigmentation(PCZH). This dermatosis described by Simoes in 1980 is characterized by a uniformly tanned macular pigmented lesion in a zosteriform distribution preceded by multiple pruritic macular pigmentation in a part of the dermatome for a period. PZMPL is not a fully understood disease entity but it is thought to be a variant of PCZH. It is differentiated from PCZH by accompanying pruritus as a prodromal symptom, a characteristic clinical course, and histological findings such as pigmentary incontinence. We report herein a case of PZMPL in a 17 year-old girl with the pigmentary skin lesion extending from the left forearm to the left chest along the Blaschkos line. The histological findings revealed increased melanin pigments in the basal layer and focal pigmentary incontinence in the upper dermis. To our knowledge, this case is the first report of PZMPL in korea thought to be the same case reported by Simoes.

The formation, maintenance, and regeneration of bone is a complex precess involving the interactions of many cellular elements with systemic and local regulators. TGF-β is one of growth factors that play an important role in the formation and remodeling of bone. In vitro studies have suggested that TGF-β regulates chondrogenesis and possibly osteogenesis by affecting replication, gene expression, and structural protein synthesis in bone formation. We investigated the effect of TGF-β1 upon fracture callus formation and maturation in mature rate. Closed femoral shaft fracture was made consistently by three point stress technique after percutaneous intramedullary nailing. TGF-β1 was injected subperiosteally at the fracture site daily for 2 weeks. We examined the effect of TGF-β1 on the fracture healing process with the radiographic, densitometric, histologic, and immunohistochemical methods. The following results were obtained. 1. Radiographic examination demonstrated that TGF-β1 injection group appeared to have more abundant callus formation and earlier callus maturation as compared to the control group. 2. Bone densitometric examination revealed that TGF-β1 injection group had higher bone mineral density and content that the control group. 3. Thermographic examination revealed that TGF-β1 injection group had higher local temperature at the injection area than the control group. 4. Histologic examination suggested that TGF-β1 stimulates and accelerates fracture callus formation and endochondral bone formation. 5. Immunohistochemical examination revealed that chondrocytes at the fracture site in the TGF-β1 injection group seemed to produce type I collagen.
