Epidermolysis bullosa dystrophica(EBD) is a rare, hereditary and chronic mechanobullous disease characterized by blistering and erosions of the skin in response to even minor trauma. A 5-year old girl visited with a complaint of continuous vesicobullous skin eruptions since birth. On examination, bullae, vesicles, atrophic scars, crusts and ero:ions were scattered on whole body. Loss of finger and toe nails, partial syndactyly of all toe webs and milia on dorsa of feet were noticed. We present a case of EBD that seems to be a recessive type considering the absence of family history with histopathologic and electron microscopic findings.

We cairried out this study to find the possibility of itch control with acupuncture under the hypothesis that antipruritic effect also exists if the itch sensation is closely allied to pain. We evaluated the effect of acupuncture on histarnine induced itch, flare and wheal in 20 healthy male volunteers aged 24 32 years old and compared it with the effect of pseudoacupuncture on them and that of no intervention on them. The results were as follows: 1. Mans of itch intensity and duration were decreased in A(session with acupuncture) and P(session with Pseudoacupuncture), compared to those of N(session with no intervention), and A was more effective in decreasing the itch intensity and its duration than P. 2. Means of maximal sizes of flare and wheal were smaller in A and P, but there was no remarkable difference between A and P.

PURPOSE: Immediate implantation presents challenges regarding site healing, osseointegration, and obtaining complete soft-tissue coverage of the extraction socket, especially in the posterior area. This last issue is addressed herein using the double-membrane (collagen membrane+high-density polytetrafluoroethylene [dPTFE] membrane) technique in two clinical cases of posterior immediate implant placement. METHODS: An implant was placed immediately after atraumatically extracting the maxillary posterior tooth. The gap between the coronal portion of the fixture and the adjacent bony walls was filled with allograft material. In addition, a collagen membrane (lower) and dPTFE membrane (upper) were placed in a layer-by-layer manner to enable the closure of the extraction socket without a primary flap closure, thus facilitating the preservation of keratinized mucosa. The upper dPTFE membrane was left exposed for 4 weeks, after which the membrane was gently removed using forceps without flap elevation. RESULTS: There was considerable plaque deposition on the outer surface of the dPTFE membrane but not on the inner surface. Moreover, scanning electron microscopy of the removed membrane revealed only a small amount of bacteria on the inner surface of the membrane. The peri-implant tissue was favorable both clinically and radiographically after a conventional dental-implant healing period. CONCLUSIONS: Secondary closure of the extraction socket and immediate guided bone regeneration using the double-membrane technique may produce a good clinical outcome after immediate placement of a dental implant in the posterior area.

Tension pneumocephalus is rare while pneumocephalus is relatively common. The former has sudden or insidious deterioration in neurologic symptoms and signs comparing to self-limited pneumocephalus. This report is of a 19 years old male with tension pneumocephalus in the right frontal lobe two underwent right frontal osteoplastic craniotomy.

PURPOSE: Estrogens control the development and cell proliferation of various tissues including the normal mammary epithelial cells, where they induce the expression of the immediate and delayed hormone-responsive genes. The proliferative effects of estrogen have been attributed to its ability to increase the expression of the key cell cycle regulatory genes responsible for cell cycle progression. However, the regulation of cell proliferation is only one aspect of estrogen function. It has also been well documented that estrogen plays a critical role in the etiology and progression of human breast and gynecological cancers. This tumorigenic effect of estrogen might be associated with its anti- apoptotic activities such as of Bcl-2 induction. The aim of this study was to clarify the role of E2IG5, which is an estrogen-induced downstream effector molecule, in breast cancer cell lines. RESULTS: This study shows that E2IG5 is a pro-apoptotic protein that is localized to the mitochondrial membrane via two distinct transmembrane domains. When over-expressed, it induces a mitochondrial permeability transition with the resultant of release cytochrome c and caspase activation. However, three out of four breast cancer cell lines lost their estrogen dependence of E2IG5 expression, which suggests the possible involvement of E2IG5 in the development of breast cancer. CONCLUSION: These results suggest that breast cancer cells may loose their pro-apoptotic signals and selectively use the proliferative mechanism of estrogen, which drives the normal mammary epithelial cells to transform into cancer cells. Further studies using breast cancer tissues will be needed.

A new technique of endoscope assisted anterior cervical foraminotomy was developed to improve the conventional microsurgical anterior cervical foraminotomy. Microsurgical anterior cervical foraminotomy provides direct anatomical decompression of the compressed nerve root by removing the spondylotic spur or disc fragment while preserving the functioning segment of the disc. The authors modified the anterior cervical foraminotomy using the MED TM(Microendoscopic discectomy) system to minimize the skin incision, and to achieve safe drilling and easy retraction. The uncinate process was drilled under endoscopic visualization through a tubular retractor. This technique has been applied to 13 patients with single level radiculopathy due to posterolateral osteophyte or soft disc herniation. The nerve roots were decompressed successfully under endoscopic control as in conventional microsurgical foraminotomy through a 2cm skin incision. Postoperatively, all patients showed improvements in their radiculopathic symptomatologies. Corresponding CT scans confirmed satisfactory anatomical decompression in all patients. This surgical technique has shown good clinical outcomes with fast recovery.

We report three cases of patient with pleomorphic xanthoastrocytoma(PXA). PXA is a clinicopathologically distinct variant of cerebral astrocytoma which is a low-grade leptomeningeal glioma affecting under the age of 30 years. This tumor has a favorable prognosis, but histological and neuroradiological findings suggest malignant brain tumor. Occasionally these may be confused with malignant gliomas. Clinical features from our three patients were manifestation of increased intracranial pressure and all cases were under the age of 30 years and females. Two patients had superficial location in the right frontal and left temporal respectively, but remaining one(case 2) which was associated with arteriovenous malformation in the left frontal region was in the right lateral ventricle. The intraoperative histological evidence by frozen biopsy suggested glioblastoma or anaplastic astrocytoma in all cases which confirmed to be PXA by postoperative histological examination. Two cases which had been resected subtotally were followed by cranial irradiation without therapeutic efficacy. Optimal management of PXA is primary surgical resection to reduce recurrence of tumor and to secure long-term survival. Therefore, differentiation of PXA from malignant brain tumors and intraoperative diagnosis of PXA is imperative to treat PXA effectively.

Behcet's syndrome is a multi-systemic and chronic disorder that affects many organs. It has been suggested that the diagnosis was based on the presence of the 'major' and 'minor' clinical criteria. When thromobophlebitis, arthritis, central nervous system or gastrointestinal lesions are also present. Behcet's syndrome will be thought to be present in the appropriate geographic area. We report a case of superior vena cava syndrome caused by Behcet's disease in a 40-year-old man with recurrent oral aphthous ulcers and skin rashes on the anterior chest wall. There were multiple thrombosis of the superior vena cava, innominate and subclavian veins. This patient also had a solitary cecal ulcer with an ileocecal fistula and downhill varix. The chest CT, veno-cavography, pulmonary angiography and colon study were taken and follow-up was performed.

The authors report a case of far lateral disc herniation at L4-5 found one year after percutaneous laser lumbar discectomy. The patient was found to be suffering from new-onset right lumbar radiculopathy 6 months after his first operation, and post operative lumbar MRI confirmed a far lateral extraforaminal disc herniation at L4-5, with compression of the nerve. This corresponded to the nucleotomy site of the probe. The patient underwent surgery employng the combined paraspinal intertransverse and interlaminar approach, and his symptoms were relieved. This case emphasizes the importance of removing nuclear material, and shows that remaining material can herniate through a percutaneous discectomy window.
