We describe a case of finger replantation after stump-plasty. The replantation was successfully carried out, but the case highlighted the importance of proper informed consent from the patient. The patient, a 39-year-old woman who incurred a sharp left middle finger amputation by a meat slicer, received initial treatment at a neighboring general hospital where she underwent stump-plasty. Records from this hospital revealed that treatment options were explained to the patient (replantation vs. stump-plasty) but that the patient had not opted for replantation. Nevertheless, the patient stated that as she had been in a state of distress, she had not fully understood what had been explained and had left the treatment decision to her treating physician. The same day, the patient visited our hospital with the amputated finger and requested a replantation. More than 7 hours had elapsed since the injury, but since the finger was iced and in good condition, we carried out the replantation, which required venous grafting. The postoperative course was without complications and the finger survived completely.<br> In the treatment of finger amputation, the gold standard is to carry out replantation, unless the patient requests otherwise. At the time of injury, patients are often in distress and lack decision-making capacity, leaving treatment decision solely to the physician. In our facility, we devote ample time to a full informed consent process, explaining treatment options, risks and benefits. This case may have been the result of an inadequate informed consent process at the first facility with the patient not fully understanding the risks and benefits; it also highlights the importance of properly conducted informed consent before surgical treatment.

A case of granular cell tumor (GCT) was reported. We encountered a 33-year-old woman with a painless, elastic, hard mass in the soft tissue of the suprasternal space. The tumor was excised with several millimeters margin of normal tissue above the deep cervical fascia and the wound was closed primarily. Histological examination on hematoxylin-eosin stain showed a tumor growth in the mid- to deep dermis and eosinophilic small granules that were consistent with granular cell tumors. Immunohistochemical studies showed positive staining for S-100 protein. We experienced a case of a granular cell tumor occurring in the suprasternal space and report the importance of including it in the differential diagnosis of subcutaneous soft tissue tumors. © 2010 Japanese Dermatological Association.

Background: We have previously reported the importance of adequate and precise arterial anastomosis and the hypothesis that, up to subzone III, fingertip amputation salvage can be achieved on arterial anastomosis alone. These findings were reported during the meeting of the Japanese Society of Reconstructive Microsurgery. This is our follow-up report with insight and opinion on the limitations of complete fingertip amputation salvage on arterial anastomosis alone. Methods: We examined 67 fingers (59 patients) with fingertip amputations presenting to our hospital between January 2005 and December 2008. Amputation levels and whether these injuries received only arterial or both arterial and venous anastomoses were noted. Fisher exact test was used to examine statistical differences between the groups. Results: Amputation levels were 11 in subzone I, 20 in subzone II, 17 in subzone III, and 19 in subzone IV. Successful replantation was achieved in 87% (58 of 67) of fingers. There was no statistically significant difference between fingers receiving arterial alone versus both anastomoses in amputations of subzones I, II, and III. Conclusions: We found that with proper postoperative congestion care, no statistically significant difference in replantation success of fingers receiving arterial anastomosis alone versus both arterial and venous were noted up to subzone III. However, in subzone IV, regardless of the postoperative congestion, compete necrosis rates are high; thus, it is speculated that a venous anastomosis is necessary for successful replantation. It is preferable to perform as many anastomoses as possible, but we believe that it is also desirable for the procedure to be fast and less invasive. In cases that have no adequate vein, fingertip replantation can be achieved on arterial anastomosis alone up to subzone III. © 2010 by Lippincott Williams & Wilkins.

We report two cases of relative rare fibrolipoma of which pre-operative diagnosis suggested malignant tumor as a potential diagnosis. Case1 : 59-year-old male presented with palpable 4 X 4cm tumor on the nuchal region. There was low and fat signal isointensity in the tumor area on MRI findings. The tumor was resected and histopathologic examination revealed fibrolipoma. Post-operative course was uneventful and no recurrence was found at 13-months follow-up point. Case 2 : 59-year-old male presented with slowly progressive mass on the nuchal region. Preoperative MRI showed 53 X 26mm tumor with combined low and fat signal isointensity. Postoperative histopathologic findings of the specimen revealed fibrolipoma. At 14-months follow-up point, no signs of recurrence were seen. The diagnosis of fibrolipoma should be considered in patients who have slow progressive mass on the nuchal region with combined low and fat signal isointensity on MRI imaging.

Our Treatment of "Coccygeal Pad" 査読あり
Higashimori T., Nakazawa H., Ito H., Katahira J., Morioka K., Kikuchi Y., Nozaki M., Sasaki K.

"Coccygeal pad" is a torose lesion of the sacrococcygeal area. Pathologically, it is hyperkeratosis and proliferation of dermal collagen. But it is rarely reported on in the plastic and reconstructive surgery fields. We experienced 5 cases in the past 6 years, and studied them retrospectively. All of the cases showed hyperkeratosis and proliferation of dermal collagen in their pathology. There was no recurrence over the last 4-years follow -up. We suggested that the etiology of coccygeal pad consists of congenital factors and chronic stimulation to the sacrococcygeal area. More research is necessary to elucidate this disease.

記述言語：日本語 掲載種別：研究論文（学術雑誌） 出版者・発行元：Burns
The regimen of burn treatment for five elderly individuals who had sustained burns that had involved the perineum included formation of colostomy to divert fecal passage. The inclusion of diverting colostomy in this group of patients had made the management of burn wound that had included eventual skin grafting technically easy. A total of 168 patients were admitted to the Burn Unit at the Kagoshima City Hospital between 1997 and 2000. There were 36 patients who had perineal involvement. Of these, there were five elderly patients aged 60 years or older. There were two men and three women who were between 60 and 81 years of age. The mean age was 72 years. The total body surface involvement varied between 7 and 55% with an average body surface involvement of 30%. The sigmoid colon was as the colostomy site. Although, two patients died of injury, the morbidities associated with colostomy procedure were nil. © 2002 Elsevier Science Ltd and ISBI. All rights reserved.

There are some reports from America that treatment of port wine stain in infants would result in more excellent response than adults. In fact, these reports say that 40 to 70% of patients younger than 7 years old would get almost 100% clearance. There appear, however, to be few papers that report such good results in Japan. This may be caused by difference between Caucasians and Japanese. So we should try new trials using Japanese port wine patients.<BR>We performed dye laser treatment using the negative pressure method on 100 cases of port stain. They received two or more treatment sessions and were evaluated by four levels of treatment response (excellent, good, fair, poor). Of the 19 patients who were younger than seven years old, 12 (63%) had excellent responses, and 6 (37%) had good responses (average number of treatment session was 3.2 times). Of the 12 patients who were from 7 to 12 years old, 2 (16,7%) had excellent responses, 6 (50.0%) had good responses (average number of treatment session was 3.9 times). Of the 16 patients who were from 13 to 18 years old, 4 (25.0%) had excellent responses, 10 (62.5%) good responses (average number of treatment session was 3.6 times). Of the 53 patients who were older than 19 years old, 15 (28.3%) had excellent responses, 26 (49.1%) had good responses (average number of treatment session was 3.1 times).<BR>What we are calling the negative pressure method is a procedure in which a laser ray is irradiated at the spot that is conditioned with the negative pressure (250-350 torr under the atmosphere pressure). This negative pressure, was realized by 'the negative pressure adapter,' that we made and attached to the handpiece of the dye laser apparatus. Suction on the small area of the surface of human skin makes its color more reddish than the color surrounding it. The mechanism of this phenomenon is aggregation of erythrocytes. We infer that ectasia of vessels, and congestion or stopping. of blood flow occurs in this area at the same time. This means an increase in the number of erythrocytes as targets of the laser rays in the vessels. Those vessels with smaller diameter, such as capillaries, usually include fewer erythrocytes. If port wine stain included such. small vessels, irradiation under negative pressure would cause more conspicuous agglutination of red blood cells, fibrin, and platelet thrombus in the vessels. In addition, our histological examination of port wine stain in the cheek showed dermis of children is thinner than adults and children's vessels of port wine stain are apt to be smaller in diameter. These might be the reasons why the negative pressure method is so effective in treating port wine stain of children.
