Assessment of Blood Volume in Liposuction Fluids Using Colorimetry.

OBJECTIVE: The possibility of using a color contrast method to evaluate blood loss during liposuction was assessed. A color chart of blood-lipid content associated with different blood volumes was developed. METHODS: Three color cards with different concentrations of blood were developed based on clinical parameters. The color cards were used to evaluate the volume of blood present in liposuction solutions obtained from 60 clinical liposuction patients. The red blood cell count also was evaluated for each patient. The data obtained using each evaluation method were compared and statistically analyzed to determine the most accurate calculation formula. RESULTS: The red blood cell counts were compared to the color card results. The paired t test results for the calculated values for the 3:1, 2:1, and 1:1 color cards and the red blood cell count values were comparable (44.3 ± 22.1 ml vs. 53.6 ± 25.0 ml, t = 10.5; 45.4 ± 19.0 ml vs. 55.2 ± 20.7 ml, t = 18.1; 41.9 ± 25.6 ml vs. 52.8 ± 28.3 ml, t = 14.0). The P values were < 0.05, and the difference between the two groups was statistically significant. The average standard error of the mean was 0.90, 0.54, and 0.77, respectively. Sixty samples were evaluated in a scatter diagram using the two detection methods. Trend analysis revealed that the two results demonstrated a linear increase (y = 5.6 + 1.1x), R2 = 0.989, indicating that the two inspection methods were highly correlated with only small errors. CONCLUSION: The colorimetric card protocol developed in this study could quickly, accurately, and conveniently calculate blood volumes in liposuction fluids, which has considerable clinical significance.

Progressive disfiguring facial masses with pupillary axis obstruction from Morbihan syndrome: A case report.

BACKGROUND: Morbihan syndrome is a rare illness, which presents with recurrent pitting edema on the upper two thirds of the face causing facial contour deformities, and Morbihan syndrome obstructing the pupillary axis with ptosis was seldomly reported. CASE SUMMARY: A 59-year-old woman presented with a 15-year history of facial swelling that progressively invaded bilaterally from the inner canthus and eyelids outwards. Imaging examination indicated that the bilateral periorbital and the left temporal soft tissues had swelling without cranium invasion. Histopathological analysis showed a large amount of lymphocyte infiltration, and immunohistochemistry showed positive expression of CD68 in clear-cut granulomas and D2-40 in the lymphatic endothelium. Finally, the clinical diagnosis of Morbihan syndrome was confirmed. CONCLUSION: Morbihan syndrome is an infrequent and refractory disease, which is characteristic with recurrent woody facial edema on the upper two thirds of the face. Solid facial edema is persistent and non-pitting, causing facial contour deformities and even vision field impairment. The diagnosis of Morbihan syndrome depends on clinical features, imaging information, and pathology. Blepharoplasty is optional to improve the visual field for these patients with severe pupillary axis obstruction.

MicroRNA-153-3p suppress cell proliferation and invasion by targeting SNAI1 in melanoma.

Malignant melanoma is one of the most common malignancies of the skin cancer and increasing evidences revealed that microRNAs (miRNAs) exert significant effects in melanoma. In the present study, the underlying function of microRNA-153-3p (miR-153-3p) in melanoma was investigated from different levels, including cell level, protein level and gene level. Our results showed that expression of miR-153-3p was lower in melanoma tissues and melanoma cells compared with the para-tumor tissue and normal melanocytes. The overexpression of miR-153-3p inhibited the cell proliferation and invasion, at the same time promoted cell apoptosis. Moreover, we identified that snail family transcriptional repressor 1 (SNAI1) is the direct target of miR-153-3p, and there is a negative correlation between miR-153-3p level and SNAI1 expression. In summary, we presented the evidences that miR-153-3p may act as a tumor suppressor by down-regulating the expression of SNAI1 in melanoma and miR-153-3p might be a potential biomarker in the diagnosis and treatment of malignant melanoma.

A de novo 1.38 Mb duplication of 1q31.1 in a boy with hemifacial microsomia, anophthalmia, anotia, macrostomia, and cleft lip and palate.

We reported a 2-year-old boy with developmental delay, mild mental retardation, and severe craniofacial malformation, including facial asymmetry with hypoplasia of the left zygoma, maxilla, and mandible, and left anophthalmia and anotia. A genome-wide screen revealed a 1.38 Mb duplication on chromosome 1q31.1, which was absent in his parents and 27 healthy controls. The duplication region contains two Refseq genes, PLA2G4A and C1orf99, which have not been reported to be implicated in craniofacial malformation. Functional studies of these genes and additional clinical analysis are necessary to elucidate the pathogenesis of craniofacial malformation.

Laser lipolysis used to treat localized adiposis: a preliminary report on experience with Asian patients.

BACKGROUND: Localized deposits of fat (adiposis) located in the face, chin, neck, and arms usually are more compact and difficult to treat using conventional liposuction. It is necessary to find an effective approach for this type of localized adiposis. This study aimed to investigate the clinical application of laser lipolysis for the treatment of localized adiposis in Asian patients. METHODS: In this study, 35 patients with localized adiposis were treated by laser lipolysis. Neodymium:yttrium-aluminum-garnet (Nd:YAG) laser energy was transferred through an optic fiber into the adipose tissue. The optimal energy and frequency of the laser were controlled precisely to melt and destroy the adipose tissue without damage to the skin and deeper tissues. The histologic study of treated adiposis tissues, the postoperation reaction, and the clinical results were observed and studied. RESULTS: After laser lipolysis, the localized adipose tissues were liquefied effectively, and the compact fibrous tissues were broken down into a looser structure. Bleeding was noted to be less than with conventional liposuction due to the coagulation of capillary vessels and the thermal effect of the laser. Laser lipolysis caused less edema, petechiae, and other postoperative complications, producing rapid recovery and satisfactory results. CONCLUSION: The Nd:YAG laser has a definite lipolysis effect on compact adipose tissue and is a more effective approach for the treatment of localized adiposis than conventional liposuction.

[Endoscope assisted transaxillary subglandular breast augmentation].

OBJECTIVE: To investigate the feasibility of endoscope assisted transaxillary subglandular breast augmentation in order to minimize the bleeding and tissue injury. METHODS: Since 2005, 27 patients underwent endoscope assisted transaxillary subglandular breast augmentation. Intraoperative bleeding and dissection injury were markedly decreased. RESULTS: There was no hematoma, seroma and infection except for one case with partial poor incision healing. 16 cases were followed-up for six months to one year. Only one case developed fibrous capsular contracture (Baker II). Good results achieved in all the other cases. CONCLUSIONS: Endoscope assisted breast augmentation can reduce the pain, bleeding and tissue injury. It can also help to put implants to right position.
