Acute necrotizing encephalopathy is a recently established disease entity, proposed by Mizuguchi et al in 1995, that shows a characteristic symmetric and multifocal involvement of both thalamus, brainstem tegmentum, cerebral periventricular white matter, and cerebellar medulla. It is known to be prevalent in Japan and other Far Ease countries. The etiology of the acute necrotizing encephalopathy remains unknown. The typical course of acute necrotizing encephalopathy is the development of the irreversible neurologic symptoms related to brain lesions. The diagnosis can be made on the basis of the combination of a typical clinical profile and characteristic radiologic findings. We experienced a first case of acute necrotizing encephalopathy in a 9 month old boy in Korea. We report this case with the brief review of related literatures.

Skeletal muscle involvement has been well documented and muscular symptoms are common in patients with polyarteritis nodosa (PAN). However, the level of muscle enzyme is uncommonly elevated and overt rhabdomyolysis is very rare. We report a case of PAN presenting as rhabdomyolysis. A 22-year-old man was admitted because of fever, severe myalgia and swelling in all extremities. Laboratory investigations showed markedly increased levels of serum creatine kinase and myoglobin. There was diffusely increased muscular uptake in bone scan. Muscle biopsy from the right deltoid revealed vasculitis involving medium-sized vessel with ischemic necrosis of muscle. On angiography, saccular aneurysms were found in multiple arterities. Therapy with methylprednisolone pulse therapy and cyclophosphamide was followed by improvement of his symptoms.

Anaphylaxis is an acute, potentially lethal, multisystem syndrome resulting from the sudden release of mast-cell- and basophile-derived mediators into the circulation. Common manifestations of anaphylactic reactions include urticaria, angioedema, nausea, vomiting, hypotension and cardiovascular collapse. Cardiovascular collapse is the first detected manifestation in up to 50% of cases in perioperative anaphylaxis, because patients are anesthetized and unable to report symptoms. A 25-year-old male presented with severe hypotension and erythema after intravenous atropine administration during general anesthesia. Postoperative laboratory findings demonstrated elevated serum tryptase and total immunoglobulin E. An intradermal test showed atropine sensitivity. Although atropine is used widely as a perioperative anticholinergic agent, it is a potential risk factor for a severe anaphylactic reaction. Therefore, prompt recognition and adequate therapeutic measures are necessary to avoid fatal consequences.

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome associated with anticonvulsant drugs is a rare but potentially life-threatening disease that occurs in response to arene oxide producing anticonvulsant such as phenytoin and carbamazepine. There have been many reports of cross reactivity among the anticonvulsants upon first exposure to the offending drugs. However, there has been few data describing the development of DRESS syndrome after switching medication from previously well-tolerated phenytoin to carbamazepine, and the induction of hypersensitivity to phenytoin by DRESS to carbamazepine. We experienced a case of a 40-yr-old man who had uncontrolled seizure that led to the change of medication from the long-term used phenytoin to carbamazepine. He developed DRESS syndrome after changing the drugs. We stopped carbamazepine and restored phenytoin for seizure control, but his clinical manifestations progressively worsened and he recovered only when both drugs were discontinued. Patch tests with several anticonvulsants showed positive reactions to both carbamazepine and phenytoin. Our case suggests that hypersensitivity to a previously tolerated anticonvulsant can be induced by DRESS to another anticonvulsant, and that the patch test may be a useful method for detecting cross-reactive drugs in anticonvulsant-associated DRESS syndrome.

Basal cell carcinoma(BCC) is the most common cancer of the skin in Korea. The lesions are most frequently found in the head and neck regions. However, its appearance on the scrotal skin is rare. We observed a case of pigmented BCC on the scrotum in a 66-year-old man. He had a well circumscribed, brown-black plaque on the scrotum for 5 years and the history of prior vasectomy about 30 years ago. The cancer was excised widely.

BACKGROUND: All clinicians are aware of the difficulty of installing a dental implant in posterior maxilla because of proximate position of maxillary sinus, insufficient bone width, and lower bone density. This study is to examine which factors will make the implantation in the posterior maxilla more difficult, and which factors will affect the postoperative implant stability in this region. METHODS: Five hundred seventy-three fixtures on the maxilla posterior were included for this study from all the patients who underwent an installation of the dental implant fixture from January 2010 to December 2014 at the Department of Oral and Maxillofacial Surgery in Pusan National University Dental Hospital (Yangsan, Korea). The postoperative implant stability quotient (ISQ) value, fixture diameter and length, presence of either bone graft or sinus lift, and graft material were included in the reviewed factors. The width and height of the bone bed was assessed via preoperative cone beam CT image analysis. The postoperative ISQ value was taken just before loading by using the OsstellTM mentor® (Integration Diagnostics AB, Gothenburg, Sweden). The t test and ANOVA methods were used in the statistical analysis of the data. RESULTS: Mean ISQ of all the included data was 79.22. Higher initial bone height, larger fixture diameter, and longer fixture length were factors that influence the implant stability on the posterior edentulous maxilla. On the other hand, the initial bone width, bone graft and sinus elevation procedure, graft material, and approach method for sinus elevation showed no significant impact associated with the implant stability on the posterior edentulous maxilla. CONCLUSIONS: It is recommended to install the fixtures accurately in a larger diameter and longer length by performing bone graft and sinus elevation.

Nevus Sebaceus is a hamartoma that has a well-documented neoplastic potential. Multiple tumors may occasionally arise, but the coexistence of 3 or more tumors is extremely rare. We report a case of nevus sebaceus in a 55-year-old female associated with syringocystadenoma papilliferum, trichoblastoma, basal cell carcinoma, sebaceous adenoma and sebaceous epithelioma.
