Lipofibromatous hamartoma of the nerve is a benign tumor, which affects the major nerves and their branches in the human body. It is often found in the median nerve of the hand and is commonly associated with macrodactyly, but it is rarely found in the digital nerves at the peripheral level. This tumor is often found in young adults and may go through a self- limiting course. However, operation is indicated when the tumor size is large or when the associated nerve compressive symptoms are present. We have experienced a rare case of lipofibromatous hamartoma that symmetrically involved the volar digital nerves of both index fingers on the ulnar side. With the aid of a microscope, we dissected and removed the tumor as much as possible without sacrificing the nerve. No sensory change occurred in both fingers and no sign of recurrence was observed upon follow-up.

In the microsurgical era, replantation with microvascular anastomosis is considered as the most superior method in aspects of texture, color, shape in case of nose amputation. There are some reported cases of replantation in nose amputation historically, but most of them are composite graft cases rather than microvascular anastomosis. Only a few cases of successful nasal replantation with microvascular anastomosis have been reported due to the reason that the size of vessels is usually very small and identifying suitable vessels for anastomosis is difficult. Microanastomosis of artery and microanastomosis of vein are ideal in replantation, but identifying suitable veins is often difficult. Without venous anastomosis, resolving the venous congestion remains to be a problem. We can carry out arteriovenous shunt if we can find two arteries in amputee. However, the smaller the size of amputee is, the more difficult it is to find two arteries. Instead of arteriovenous shunt, we can try external venous drainage(frequently swab, pin-prick, stab incision, IV or local heparin injection, dropping, apply of heparin-soaked gauze, use of medical leech). Here, we present three cases of replantation with microscopical arterial anastomosis (one angular artery, two dorsal nasal arteries) and external venous drainage (stab incision, application of medical leech and heparin-soaked gauze) even though the size of amputee may be as small as 1.5x1.0 cm. In all cases, surgical outcomes were excellent in cosmetic and functional aspects. This report describes successful replantation by microvasular anastomosis in case that suitable veins are not found.

PURPOSE: The aim of this study was to investigate the characteristics of Acute Kidney Injury Network (AKIN)-defined nephrotoxicity in patients undergoing intravenous colistimethate sodium (CMS) therapy for major burns. METHODS: This retrospective study included burn patients who received more than 48 h of intravenous CMS between September 2009 and December 2015. Data collection was performed using the institution's electronic medical record system. Patients assigned to the developed nephrotoxic group experienced aggravation of current AKIN stage during CMS treatment; those assigned to the non-nephrotoxic group experienced no change in current or exhibited improved AKIN stage during CMS therapy. RESULTS: A total of 306 patients were included in this study. All patients were grouped according to AKIN stage: AKIN 0 (n=152); AKIN 1 (n=6); AKIN 2 (n=9); AKIN 3 (n=139). The baseline creatinine (Cr) level was 0.73 mg/dL. The incidence of nephrotoxicity was 50.3% according to AKIN stage; overall mortality was 45.8%. The non-nephrotoxic group consisted of 127 (74.7%) patients and 43 (25.3%) were in the developed nephrotoxic group. In patients requiring continuous renal replacement therapy (CRRT), baseline Cr level was 0.83 mg/dL, pre-CMS Cr level was 1.17 mg/dL, and post-CMS Cr level was 1.34 mg/dL. CONCLUSION: CMS can be administered without signs of nephrotoxicity for a certain period (approximately 1 week), it can be used relatively safely for 2 weeks. Application of CMS is a reasonable option for treating infections caused by multi-drug resistant gram-negative bacteria in patients with major burns. The caution should be exercised nevertheless.
