概要: A clinical study was conducted on 16 patients with malignant melanoma who were registered between 1986 and 1990 by the registration committee for malignant head and neck tumors of Niigata prefecture. Ten tumors originated in the nasal cavity, 3 in the cervical skin, 2 in the paranasal sinus, and 1 in the lower gingival mucosa. The mean age of patients was 64.8years, and 10 were men and 6 were women. The inital symptom of tumors originating in the nasal cavity or paranasal sinus was epistaxis or nasal obstruction, whereas that of tumors originating in the cervical skin or the lower gingival mucosa was tumor formation. The mean duration from the appearance of the initial symptom to consultation was 5.0 months, that of tumors originating in the mucosa was 3.8 months, and that of tumors in the skin was 10.0 months. The mean duration was significantly shorter in mucosal tumors than in cutaneous ones. The most common local findings were black or black-brown tumor, black or black-brown pigmentation, or both. However, in 4 nasal and paranasal tumors, dark-red or grey-white tumor that resembled nasal polyp was recognized. Radical treatment was performed in 14 cases, and palliative treatment in 2. In radically treated cases, surgery was the main therapy, and chemotherapy or radiotherapy ware used adjuncts. Palliative treatment consisted of radiotherapy or injection of interferon. At this time, 6 patients are tumor free, 3 are alive with tumor, and 7 have died. As the major cause of death was distant metastasis, more effective general therapy is needed. 続きを見る

概要: The analysis of the student opinion on PBL tutorial was done from questionnaires from 2006 to 2010. Four points of the following were summarized. 1. The satisfaction to PBL tutorial learning, the student that it seems that it is high of the self-learning tropism or the student who had a tutor performing a commentary carefully is high, but there are not many at all the opinions. 2. The opinion of one majority who are not above, a voice to expect acquisition of the knowledge by the conventional lecture is accounted for by the opinion that is negative for most, PBL tutorial. 3. There are particularly a lot of opinion to report the noncooperativity of the student in the group assignment to report deficiency of the schedule setting of PBL tutorial learning, numerousness of the number of the scenarios and deficiency at investigation time, difficulty of the learning without academic back ground. 4. Opinion to nominate lack of zeal of tutor and lack of the leadership are reached to the number that cannot be ignored. 続きを見る

概要: 当科で1989 年から2009 年までに経験した脂肪腫32 例について臨床的および病理組織学的に検討を行い,自験例の特徴を明らかにするために,本邦他施設の多数例報告論文との比較検討も行った。自験例では男女比は1.1:1であり,ほとんどが40 歳以上であった。発生部位は頬粘膜が11 例(34%),舌が8例(25%),下唇が7例(22%)であり,1例は顎骨内に認められた。臨床診断は脂肪腫が16 例(50%),線維腫が7例(22%),良性腫瘍が6例(19%)であった。腫瘍の最大径は最小が6mm,最大が50mm で,平均が15mm であった。病理組織学的診断は単純性脂肪腫が18 例(56%),線維脂肪腫が12 例(38%),化骨性脂肪腫,粘液脂肪腫が各1例であった。一方,本邦他施設の多数例報告論文をまとめると,発生部位は頬粘膜が75 例(42%),舌が32 例(18%),下唇が22 例(12%),歯肉が21 例(12%),口底が11 例(6%)であった。病理組織学的診断は単純性脂肪腫が126 例(75%),線維脂肪腫が33 例(20%)であり,他はほとんどみられなかった。自験例と本邦他施設の報告例を比較すると,顎骨内に発生した1例,および病理組織学的に化骨性脂肪腫,粘液脂肪腫と診断された各1例はきわめて珍しい例であった。<br />In this report, we examined 32 cases of lipoma treated at our department from 1989 to 2009, and we compare these cases with 200 cases reported before in Japan. In our cases, the male-female ratio was 1.1:1 and most of the patients were over 40 years of age. The site of involvement was buccal mucosa in 11 cases (34%), tongue in 8 cases (25%) and lower lip in 7 cases (22%). The clinical diagnosis was lipoma in 16 cases (50%), fibroma in 7 cases (22%) and benign tumor in 6 cases (19%). The size of tumor was ranged from 6mm to 50mm, and the mean size was 15mm. The histopathological diagnosis was simple lipoma in 18 cases (56%), fibrolipoma in 12 cases (38%), and the other 2 cases were osteolipoma and myxolipoma. Consider about the cases reported before in Japan, the site of involvement was buccal mucosa in 75 cases (42%), tongue in 32 cases (18%), lower lip in 22 cases (12%), gingival in 21 cases (12%) and oral floor in 11 cases (6%). The histopathological diagnosis was simple lipoma in 126 cases (75%), fibrolipoma in 33 cases (20%) and the other type of lipomas were rarely found. In our cases, intraosseous lipoma, ossifying lipoma, and myxolipoma were extremely rare. 続きを見る

概要: The purpose of this study was to evaluate bone bridge formation after early secondary bone grafting in patients with com plete cleft lip and palate, using dental X-ray films and X-ray computed tomography. The subjects were 73 patients (86 alveolar clefts) received two-stage palatoplasty with a Hotz plate (two-stage group), followed by bone grafting using autogenous particulate cancellous bone and marrow harvested from the iliac crest. For comparison with the two-stage group, 20 patients (22 alveolar clefts) who received one-stage palatoplasty before the age of two were selected as a control group (one-stage group). The presence of bone bridge, upper margin of bone bridge and both vertical and buccolingual length of bone bridge were compared statistically between the two groups. The vertical length of the bone bridge above 11mm, which was the same length as the maxillary incisor's root, was observed to be 87.7% (unilateral) and 66.6% (bilateral) in two-stage group, while it was 62.6% (unilateral) and 33.4% (bilateral) in one-stage group. The upper margin of the bone bridge was more than three-quarters of the length of the central incisor's root both in unilateral and bilateral cases in the two-stage group than in the one stage group statistically (unilateral p<0.005, bilateral p<O.0005). It is concluded that two-stage group may improve the axis of the central incisor and enable eruption of lateral incisor and canine on grafted bone.<br />Hotz床併用二段階口蓋形成手術を施行した唇顎口蓋裂患者の顎裂部骨移植の早期術後成績について調査を行った。対象は1996年から2000年までに二次的顎裂部腸骨移植が施行された唇顎口蓋裂73名86顎裂(以下、二段階群)、および、対照として他院にて2歳以前に一期的に口蓋形成手術が行われ、当科で同時期に二次的顎裂部骨移植術が施行された唇顎口蓋裂20名22顎裂(以下、一段階群)である。調査方法は歯科用口内Ⅹ線写真を用いて、骨架橋形成の有無、垂直的骨架橋幅、歯槽頂の高さを、Ⅹ線CT軸位断画像を用いて、鼻腔側部と歯槽頂部の2か所について頬舌的骨架橋幅を調査した。検定方法はXX検定、Mann-WhitneyのU検定を用いた。その結果、二段階群は垂直的骨架橋幅が上顎中切歯および側切歯の平均歯根長である11mm以上のものが片側性84.7%、両側性66.7%であり、一段階群の片側性62.6%、両側性33.3%よりも片側性において有意に高く(p<0.05)、歯槽頂の高さは上顎中切歯歯根の4分の3以上であるものが二段階群片側性88.1%、両側性77.8%、一段階群片側性56.3%、両側性なしと比較して有意に高く(片側性p<0.005、両側性p<0.0005)、二段階群は上顎切歯の歯軸の改善や側切歯および犬歯の萌出誘導に有利であると考えられた。 続きを見る
