RESUMO
Background: Subungual exostosis is a type of heterotopic ossification, which often has unclear margins. Therefore, marginal resection may cause recurrence and wide resection is sometimes required to achieve a complete cure. However, wide resection may cause postoperative nail deformity and revision of this deformity is generally difficult. The primary treatment of subungual exostosis is surgical treatment, and there have been no comprehensive reports on the efficacy of adjunctive treatments. Although postoperative electron beam irradiation has been successfully used after heterotopic ossification excision to prevent recurrence, there are no reports on the use of this procedure following subungual exostosis resection. Case Description: Herein, we report a case of refractory subungual exostosis that developed as a result of chronic irritation and inflammation caused by an ingrown nail and recurred after initial resection. We performed marginal resection of the lesion to preserve the nail matrix and nail bed as possible, a two-stage skin grafting procedure, and electron-beam irradiation to prevent recurrence. Conclusions: Excellent results were achieved both in terms of complete cure and cosmetic appearance, suggesting that electron-beam irradiation following refractory subungual exostosis excision may help prevent its recurrence. We expect a further study including many cases of subungual exostosis treated with postoperative electron-beam irradiation to be conducted.
RESUMO
Background: Various flap monitoring techniques have been used in the early detection of anastomotic thrombus; however, the use of automatic and continuous monitoring methods is presently uncommon. The purpose of this study was to investigate trends in interstitial fluid glucose concentration (IFG) in flap monitoring by measuring IFG automatically and continuously. Methods: Nine patients underwent unilateral breast reconstruction using a transverse rectus abdominis myocutaneous flap with vascular anastomosis. Two IFG measuring devices were attached to each patient. One device was attached to the flap (flap IFG) and the other to the healthy breast (control IFG). In each case, flap IFG, control IFG, and IFG ratio (flap IFG/control IFG) were recorded in the initial 72â h post-surgery (first half) and also in the subsequent 72â h (second half). In all of the cases, the mean values recorded in the first half and those in the second half were compared. Results: All flaps survived. The flap IFG didn't fall below 40â mg/dL in the first half. The minimum flap IFG and IFG ratio were 42â mg/dL and 0.55 in the first half. The flap IFG was significantly higher in the first half than in the second half in all cases, and the IFG ratio was similar in 8 cases. Furthermore, mean flap IFG and mean IFG ratio in all cases in the first half were significantly higher than in the second half. Conclusions: IFG measurements may complement conventional flap monitoring, particularly in the early postoperative period.
Historique: Diverses techniques de surveillance du lambeau sont utilisées pour favoriser le dépistage précoce du thrombus anastomotique, mais peu de méthodes de surveillance automatique et continue sont utilisées en ce moment. La présente étude visait à examiner les tendances du glucose interstitiel (GI) lors de la surveillance du lambeau par une mesure automatique et continue. Méthodologie: Neuf patientes ont subi une reconstruction mammaire unilatérale au moyen d'un lambeau myocutané du grand droit transverse avec anastomose vasculaire. Chaque patiente était dotée de deux dispositifs de mesure du GI. L'un d'eux était fixé au lambeau (GI du lambeau) et l'autre au sein en bonne santé (GI témoin). Dans chaque cas, les chercheurs ont enregistré le GI du lambeau, le GI témoin et le ratio du GI (GI du lambeau/GI témoin) pendant les 72 premières heures suivant l'opération (première moitié), puis pendant les 72 heures suivantes (deuxième moitié). Dans tous les cas, les chercheurs ont comparé les valeurs moyennes enregistrées pendant la première moitié à celles enregistrées pendant la deuxième moitié. Résultats: Tous les lambeaux ont survécu. Le GI du lambeau n'a pas chuté sous 40â mg/dl pendant la première moitié. Le ratio minimal du GI était de 42â mg/dl et 0,55 pendant la première moitié. Dans tous les cas, le GI du lambeau était beaucoup plus élevé pendant la première moitié que pendant la deuxième moitié, et le ratio du GI était semblable dans huit cas. De plus, dans tous les cas, le GI moyen du lambeau et le ratio moyen du GI était beaucoup plus élevé pendant la première moitié que la deuxième. Conclusions: Les mesures de GI peuvent compléter la surveillance habituelle du lambeau, notamment au début de la période postopératoire.
RESUMO
Breast reconstruction using silicone breast implants (SBIs) has been performed for many patients in Japan under the initiative of the Japan Oncoplastic Breast Surgery Society (JOBSS) since SBIs were first covered by insurance in 2013. A change in the lineup of available SBIs owing to the Allergan crisis caused a decrease in the availability of SBIs appropriate to Japanese breast contours. Recently, the number of immediate implant-based breast reconstructions (IBRs) was approximately 4,000 in one year and was slightly decreasing. The SBI is generally placed under the pectoralis major muscle. Because the number of patients with one-stage, implant-based operative indications is small, an acellular dermal matrix is not available in Japan, and the complication rate in one-stage, IBR is high, most immediate, IBRs are performed in two stages. The prevalence of immediate, one-stage, IBRs is approximately 10%. Fat grafting by injection using Coleman's technique is performed in many hospitals under the JOBSS initiative as a surgery combined with SBI insertion. Complications after SBI placement may be less common in Japan than those in other countries. Japanese breast reconstructive surgeons undertake preventive measures to lessen these complications according to guidelines and experts' opinions, which may contribute to the low complication rate after SBI placement. The total reported number of patients with breast implant-associated anaplastic large cell lymphoma is four, and no patients have died because of this disease. In Japan, procuring informed consent and diagnosing and treating this disease are performed according to the JOBSS guidelines.
RESUMO
Revascularization surgery was first considered for the treatment of ulcers in patients with critical limb ischemia (CLI). However, it may not be indicated for patients with severe infections or peripheral vascular occlusions. Although blood purification therapy is adjuvant therapy for such patients, it is not yet widely used due to insurance coverage. We report a case of a refractory heel ulcer with moderate osteomyelitis and cellulitis that was not amenable to revascularization. Treatment with the adsorptive blood purifier rheocarna® (Kaneka Corporation; Osaka, Japan) resulted in complete epithelialization of the ulcer and control of inflammation. Although this case required careful follow-up, we believe rheocarna might be a promising treatment option for patients with CLI who do not respond to revascularization. Rheocarna could improve peripheral blood flow and control inflammation by improving antibiotic drug delivery.
