RESUMEN
Scabies is a common skin disorder, caused by the ectoparasite Sarcoptes scabiei. The scabies mites burrow is highly diagnostic but illegible by the naked eye, because it is tiny and may completely be obscured by scratch and crust. The classic technique is opening the end of an intact mite burrow with a sharp instrument and inspecting its contents in the light microscope under loupe vision. Dermatoscope is a new method to diagnose scabies, with the advantages of non-invasive and more sensitive. This study verified the characteristic manifestations of scabies under dermoscopy. Under the closer examination of the curvilinear scaly burrow, the scabies mite itself may be seen as a dark equilateral triangular structure, which is often referred to as a "jet with contrail." Besides, this study found that the positive detection rate of microscopic characteristic manifestations under the dermoscopy ordered by the external genitals, the finger seams and the trunk, which were statistically different (P-value < 0.05). Of note, this is the first study to explore the regional distribution of the characteristic dermoscopic manifestations of scabies. We are the first to propose to focus on examining the external genitalia and finger seams with dermoscopy.
RESUMEN
<p><b>OBJECTIVE</b>To evaluate the donor risks and potential recipient benefits of living donor liver transplantation (LDLT) for adult patients with hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>From January 2002 to December 2006, a total of 27 LDLT for HCC patients were performed in our center, of which 25 received right lobe grafts and 2 received dual grafts. The clinical and follow-up data of these 27 recipients and 29 donors were analyzed retrospectively.</p><p><b>RESULTS</b>Of the 29 donors, the overall complication rate was 17.24% (5 cases). Two cases (6.90%) experienced major complications (one with intra-abdominal bleeding and one with portal vein thrombosis) and three cases (10.34%) experienced minor ones (fat necrosis and infection of the surgical skin wound in one, pleural effusion in another and transient chyle leakage in the third). All donors were fully recovered and returned to their previous work. No recipients developed small-for-size syndrome. The overall HCC patients survival rate at 1- and 3-years was 84.01% and 71.40%, respectively, similar to that of patients undergoing LDLT for various nonmalignant diseases during the same period (P > 0.05).</p><p><b>CONCLUSION</b>Although further study is needed to fully assess the risks and benefits of LDLT for the HCC patients and donors, our present results preliminarily suggest that LDLT offers an acceptable chance and duration of survival in patients with HCC, and it is a relatively safe procedure.</p>
