PURPOSE: Marjolin's ulcer is rare but highly aggressive malignant cancer that is associated with chronic, nonhealing wounds such as burn wound. There are no confirmed effective protocols for treatment of this disease. This study was conducted to describe the clinical presentation and treatment modalities of Marjolin's ulcer in our hospital. METHODS: This was a retrospective study of Marjolin's ulcer. 20 cases were histologically confirmed malignant skin cancer seen at Chonbuk National University Hospital from January 2000 to December 2011. Data were retrieved from patients' medical records and photographs. RESULTS: The total 20 cases of Marjolin's ulcer were studied. Squamous cell carcinoma was the most common pathological type in 20 patients (100%). Lymph node metastasis at the time of diagnosis was recorded in 3 patient (15%). Wide excision was the most common surgical procedure performed in 17 patients (85%) of cases. The reconstruction modalities were various as free flap 3 patients (15%), skin graft 13 patients (65%), local advancement flap 2 patients (10%) and regional flap 1 patient (5%). Local recurrence was noted in 3 patients (15%) who had surgical treatment. And one patient (5%) expired in hospital. CONCLUSION: Marjolin's ulcer is an infrequent lesion. Unfortunately the diagnosis and treatment are often delayed. If the wound was histologically confirmed, aggressive excision and reconstruction is warranted in these highly malignant skin cancer. Early recognition and aggressive treatment of Marjolin's ulcers are essential to improve outcomes.

BACKGROUND: The reconstruction of large skin and soft tissue defects on the lower extremities is challenging. The skin graft is a simple and frequently used method for covering a skin defect. However, poor skin quality and architecture are well-known problems that lead to scar contracture. The collagen-elastin matrix, Matriderm, has been used to improve the quality of skin grafts; however, no statistical and objective review of the results has been reported. METHODS: Thirty-four patients (23 male and 11 female) who previously received a skin graft and simultaneous application of Matriderm between January 2010 and June 2012 were included in this study. The quality of the skin graft was evaluated using Cutometer, occasionally accompanied by pathologic findings. RESULTS: All 34 patients showed good skin quality compared to a traditional skin graft and were satisfied with their results. The statistical data for the measurement of the mechanical properties of the skin were similar to those for normal skin. In addition, there was no change in the engraftment rate. CONCLUSIONS: The biggest problem of a traditional skin graft is scar contracture. However, the dermal matrix presents an improvement in skin quality with elastin and collagen. Therefore, a skin graft along with a simultaneous application of Matriderm is safe and effective and leads to a significantly better outcome from the perspective of skin elasticity.

The cytogenetic analysis of mesenchymal stromal cells (MSCs) is essential for verifying the safety and stability of MSCs. An in situ technique, which uses cells grown on coverslips for karyotyping and minimizes cell manipulation, is the standard protocol for the chromosome analysis of amniotic fluids. Therefore, we applied the in situ karyotyping technique in MSCs and compared the quality of metaphases and karyotyping results with classical G-banding and chromosomal abnormalities with fluorescence in situ hybridization (FISH). Human adipose- and umbilical cord-derived MSC cell lines (American Type Culture Collection PCS-500-011, PCS-500-010) were used for evaluation. The quality of metaphases was assessed by analyzing the chromosome numbers in each metaphase, the overlaps of chromosomes and the mean length of chromosome 1. FISH was performed in the interphase nuclei of MSCs for 6q, 7q and 17q abnormalities and for the enumeration of chromosomes via oligo-FISH in adipose-derived MSCs. The number of chromosomes in each metaphase was more variable in classical G-banding. The overlap of chromosomes and the mean length of chromosome 1 as observed via in situ karyotyping were comparable to those of classical G-banding (P=0.218 and 0.674, respectively). Classical G-banding and in situ karyotyping by two personnel showed normal karyotypes for both cell lines in five passages. No numerical or structural chromosomal abnormalities were found by the interphase-FISH. In situ karyotyping showed equivalent karyotype results, and the quality of the metaphases was not inferior to classical G-banding. Thus, in situ karyotyping with minimized cell manipulation and the use of less cells would be useful for karyotyping MSCs.

BACKGROUND: Fingertip injuries involving subtotal or total loss of the digital pulp are common types of hand injuries and require reconstruction that is able to provide stable padding and sensory recovery. There are various techniques used for reconstruction of fingertip injuries, but the most effective method is functionally and aesthetically controversial. Despite some disadvantages, cross-finger pulp flap is a relatively simple procedure without significant complications or requiring special techniques. METHODS: This study included 90 patients with fingertip defects who underwent cross-finger pulp flap between September 1998 and March 2010. In 69 cases, neurorrhaphy was performed between the pulp branch from the proper digital nerve and the recipient's sensory nerve for good sensibility of the injured fingertip. In order to evaluate the outcome of our surgical method, we observed two-point discrimination in the early (3 months) and late (12 to 40 months) postoperative periods. RESULTS: Most of the cases had cosmetically and functionally acceptable outcomes. The average defect size was 1.7x1.5 cm. Sensory return began 3 months after flap application. The two-point discrimination was measured at 4.6 mm (range, 3 to 6 mm) in our method and 7.2 mm (range, 4 to 9 mm) in non-innervated cross-finger pulp flaps. CONCLUSIONS: The innervated cross-finger pulp flap is a safe and reliable procedure for lateral oblique, volar oblique, and transverse fingertip amputations. Our procedure is simple to perform under local anesthesia, and is able to provide both mechanical stability and sensory recovery. We recommend this method for reconstruction of fingertip injuries.

Background:
Although international guidelines recommend palliative care approaches for many serious illnesses, the palliative needs of patients with serious illnesses other than cancer are often unmet, mainly due to insufficient prognosis-related discussion. We investigated physicians' and the general public's respective attitudes toward prognostic disclosure for several serious illnesses.
Methods:
We conducted a cross-sectional survey of 928 physicians, sourced from 12 hospitals and the Korean Medical Association, and 1,005 members of the general public, sourced from all 17 administrative divisions in Korea.
Results:
For most illnesses, most physicians (adjusted proportions – end-organ failure, 99.0%; incurable genetic or neurologic disease, 98.5%; acquired immune deficiency syndrome [AIDS], 98.4%; stroke or Parkinson's disease, 96.0%; and dementia, 89.6%) and members of the general public (end-organ failure, 92.0%; incurable genetic or neurologic disease, 92.5%; AIDS, 91.5%; stroke or Parkinson's disease, 92.1%; and dementia, 86.9%) wanted to be informed if they had a terminal prognosis. For physicians and the general public, the primary factor to consider when disclosing terminal status was “the patient's right to know his/her condition” (31.0%). Yet, the general public was less likely to prefer prognostic disclosure than physicians. Particularly, when their family members were patients, more than 10% of the general public did not want patients to be informed of their terminal prognosis. For the general public, the main reason for not disclosing prognosis was “psychological burden such as anxiety and depression” (35.8%), while for the physicians it was “disclosure would have no beneficial effect” (42.4%).
Conclusion
Most Physicians and the general public agreed that disclosure of a terminal prognosis respects patient autonomy for several serious illnesses. The low response rate of physicians might limit the generalizability of the results.
