Confluent and reticulated papillomatosis(CRP) is a rare dermatosis. The lesions are hyperkeratotic, verrucous papules and plaques, resulting in a confluence of lesions centrally and a reticulated pattern at the periphery. It is more common in women and during puberty. The histopathological findings show papillomatosis, hyperkeratosis and a sparse superficial perivascular lymphocytic infiltrate. We report a case of CRP that responded to oral etretinate in an 18-year-old man.

PURPOSE: Acute appendicitis has atypical clinical findings that make accurate preoperative diagnosis difficult. The aim of this study was to investigate the usefulness of laboratory analyses, especially total leukocyte count (WBC) and neutrophil count, C-reactive protein (CRP) in the diagnosis of acute appendicitis. METHODS: Sixty-nine patients who visited to the Department of Surgery, Sangju St. Mary's hospital with the diagnosis suspected acute appendicitis were studied. WBC, neutrophil count, CRP, and erythrocyte sedimentation rate (ESR) were analysed. Surgery for acute appendicitis was performed in fifty-four patients. According to histopathological findings of the appendix, the patients were divided into four groups: complicated (20 patients with perforated & gangrenous type), suppurative (9 patients), phlegmonous (25 patients), and normal (15 patients). The sensitivity and specificity of the laboratory tests in the diagnosis of acute appendicitis were calculated. RESULTS: The sensitivity of WBC>10, 000/mm3, neutrophil count>70% or >7, 000/mm3, and CRP>12 mg/L in acute appendicitis was 68.5%, 85.1%, and 74.0%, and the specificity was 86.0%, 73.3%, and 80.0% respectively. The combination of neutrophil count or CRP was 94.4% sensitivity. The severity of appendicitis had positive relationship with WBC, neutrophil count, and CRP (P=0.0001, P<0.0001, and P= 0.0014, respectively). The appendicitis and normal groups were significantly different in WBC, neutrophil count, and CRP (P<0.05). CONCLUSION: WBC, neutrophil count, and CRP have diagnostic value among the myriad causes of right lower quadrant abdominal pain and show a positive relationship with the severity of appendicitis.

Hitiocytosis X, recently termed Langergans cell histiocytosis, is a rare disease histologically characterized by an abnormal proliferation of histiocytes, and of which the pathophysiology is still ambiguous. The clinical presentation is highly varied. Typically, there is a solitary or multiple bony involvements, and less frequently, lesions are found in other organs such as the lungs, liver, lymph nodes, skin, and mucosae. Interestingly, so far, there has been no report which shows multiple developments in both soft and hard tissues. In this report, we present a case of hitiocytosis X in both mandible and lung. This may provide some information for understanding the pathophysilogy of the histiocytosis X.

Mandibular arteriovenous malformations(AVM) are relatively rare and potentially life threatening lesions. Surgical treatment consists of wide resection of the mandible, which is difficult and potentially hazardous due to significant blood loss during surgery. Therefore, some authors advocate that transvenous embolization may be a safer and more effective method in the treatment of mandibular AVM. We report a treatment case of mandibular AVM in a 9-year-old-girl for episodes of spontaneous bleeding for 6 days using by selective transarterial embolization ,direct puncture embolization and microcoil embolization.

As dental implant surgery and bone grafts were widely operated in Korean dentist, many bone substitutes are commercially available, currently. For commercially used in Korea, all bone substitutes are firstly evaluated by the Ministry of Health and Welfare (MOHW) for safety and efficacy of the product. After being priced, classified, and registration by the Health Insurance Review and Assessment Service (HIRA), the post-application management is obligatory for the manufacturer (or representative importer) to receive a certificate of Good Manufacturing Practice by Ministry of Food and Drug Safety. Currently, bone substitutes are broadly classified into C group (bone union and fracture fixation), T group (human tissue), L group (general and dental material) and non-insurance material group in MOHW notification No. 2018-248. Among them, bone substitutes classified as dental materials (L7) are divided as xenograft and alloplastic bone graft. The purpose of this paper is to analyze alloplastic bone substitutes of 37 products in MOHW notification No. 2018-248 and to evaluate the reference level based on the ISI Web of Knowledge, PubMed, EMBASE (1980–2019), Cochrane Database, and Google Scholar using the criteria of registered or trademarked product name.
