We present a 35-year-old male who, 9 years ago, had his right orbit and face injured in a gun blast accident resulting in severe cicatrical ectropion of the right lower lid. A large advancement facial flap with incision at the naso-labial fold was designed to repair the skin defect, and a strip of autologous fascia lata was grafted in the lower lid to serve as a static sling. The facial flap was dissected and elevated at the subcutaneous fat layer. With adequate separation of the flap and suspension sutures at the undersurface of the flap, tension free closure of the wound was obtained and the ectropion completely corrected. The postoperative course was uneventful and the patient very satisfied with the results.

Patients with osmidrosis are particularly concerned with malodour elimination after surgery. Open excision of the subcutaneous apocrine glands through a small incision seems to be the most logical and effective method available for osmidrosis. However, literature on long-term results and complications after such surgery based on large case series are rare. From January 2005 to May 2008, 256 consecutive patients with axillary osmidrosis were treated with our subcutaneous glands excision technique, of which 206 could be followed up from 3 to 40 (mean 18.1) months. Patients ranged in age from 14 to 52 (mean 23.4) years and the female to male ratio was 131:75. Among the 206 cases, 183 cases had family histories of the disease and 16 were accompanied with axillary hyperhidrosis. Postoperatively, as high as 97% of the patients achieved good results in terms of malodour elimination during the follow-up period. All patients reported reduction in axillary sweating; among them 16 patients complicated with axillary hyperhidrosis reported a significant reduction. Axillary hair growth was much reduced in most (95%) patients, and four female patients complicated with axillary hirsutism were extremely satisfied with axillary hair reduction. Early postoperative complications included haematoma ( .7%), seroma (1.2%), folding of skin flap ( .7%), pressure blister (3.6%), contact dermatitis (1%), superficial epidermis necrosis (37%), small granuloma ( .5%), wound infection ( .7%) and wound dehiscence (5.1%). Late complications included comedones (1.2%), milia ( .5%), sebaceous cyst (or with abscess)( .7%), hypertrophic scar (1%), temporary skin pigmentation ( .5%), temporary mild lactation ( .5%) and temporary sweating outside the axillae (1%). In general, 196 patients (95%) were totally satisfied with the procedure and nine (4.4%) patients partially satisfied, with only one ( .5%) regretful. The procedure has a very high success rate with minor complications. It should become the preferred procedure for the surgical treatment of axillary osmidrosis.

We report on a 16-year-old boy with Noonan syndrome who had short stature, hypertelorism, mild hearing loss, webbed neck, pectus deformities, hypertrophic cardiomyopathy, low posterior hairline, redundant skin, café au lait spot, curled hairs, foetal pads, and undescended testes. The father and a sister of the boy were also found with mild webbed neck, being possibly mildly affected individuals. The significant webbed-neck deformity of the boy was completely corrected by subcutaneous resection of the proximal half of the hypertrophic fascia bands, through small incisions hidden within the hairline. The advantage of this procedure is simple, safe and effective, with no visible scar on the surface of the neck.

Axillary osmidrosis is a troublesome and distressing problem. Medical treatment is only temporally effective. From March 2003 to November 2004, 36 patients with axillary osmidrosis (nine cases combined with axillary hyperhidrosis) have been treated by excision of the subcutaneous glands via a small transverse incision, of which 31 cases could be followed up for a minimum of 3 months (average 7.3 months). In terms of malodour elimination, 30 cases had good results, one had fair result, and none had a poor result. All patients reported significant reducing of sweating, especially those with hyperhidrosis. Postoperative complications were minor, including small haematoma (one axillae), small seroma (two axillae), and superficial epidermal necrosis (21 axillae) which were all spontaneously healed within a week. Twenty-nine (93.5%) patients were very satisfied with the procedure and two (6.5%) patients satisfied, with none regretful. The operation has the advantage of a high success rate in radical elimination of the malodour with minor complications.

Presenilin 1 (PS1) is required for the proteolytic processing of Notch and the beta-amyloid precursor protein (APP), molecules that play pivotal roles in cell-fate determination during development and Alzheimer's disease pathogenesis, respectively. In addition, PS1 interacts with beta-catenin and promotes its turnover through independent mechanisms. Consistent with this activity, we report here that PS1 is important in controlling epidermal cell proliferation in vivo. PS1 knockout mice that are rescued through neuronal expression of human PS1 transgene develop spontaneous skin cancers. PS1-null keratinocytes exhibit higher cytosolic beta-catenin and beta-catenin/lymphoid enhancer factor-1/T cell factor (beta-catenin/LEF)-mediated signaling. This effect can be reversed by reintroducing wild-type PS1, but not a PS1 mutant active in Notch processing but defective in beta-catenin binding. Nuclear beta-catenin protein can be detected in tumors. Elevated beta-catenin/LEF signaling is correlated with activation of its downstream target cyclin D1 and accelerated entry from G(1) into S phase of the cell cycle. This report demonstrates a function of PS1 in adult tissues, and our analysis suggests that deregulation of beta-catenin pathway contributes to the skin tumor phenotype.

OBJECTIVE: To examine the relationship between smoking and the risk of tuberculosis (TB) mortality in a large population-based case-control study in China using an alternative control group selection design. METHODS: During 1989-1991, a nationwide mortality survey was conducted of deaths among adults from 1986 to 1988. Surviving spouses or other informants provided detailed information about their own as well as the deceased person's smoking history. For the present study, all persons who died of TB at age >/=40 were used as cases, whereas all surviving spouses of deceased persons who died from causes other than those attributed to smoking were used as controls. RESULTS: It was estimated that for 22.5% of men and 6.6% of women, smoking was a contributing factor for TB deaths. Although variations in TB death rates by smoking status were not obvious before the age of 60, these differences increased substantially with age thereafter. This trend occurred in both urban and rural areas, although rural TB death rates were double those observed in urban areas. CONCLUSIONS: Tobacco smoking was associated with a large number of deaths from TB in China. The current study confirms results from previous studies about the relationship between smoking and TB mortality.

Forward-backward multiplicity correlation strengths have been measured with the STAR detector for Au+Au and p+p collisions at sqrt[s_{NN}]=200 GeV. Strong short- and long-range correlations (LRC) are seen in central Au+Au collisions. The magnitude of these correlations decrease with decreasing centrality until only short-range correlations are observed in peripheral Au+Au collisions. Both the dual parton model (DPM) and the color glass condensate (CGC) predict the existence of the long-range correlations. In the DPM, the fluctuation in the number of elementary (parton) inelastic collisions produces the LRC. In the CGC, longitudinal color flux tubes generate the LRC. The data are in qualitative agreement with the predictions of the DPM and indicate the presence of multiple parton interactions.

We report the first experimental characterization of efficiency and spectrum enhancement in a laser-seeded free-electron laser using a tapered undulator. Output and spectra in the fundamental and third harmonic were measured versus distance for uniform and tapered undulators. With a 4% field taper over 3 m, a 300%(50%) increase in the fundamental (third harmonic) output was observed. A significant improvement in the spectra with the elimination of sidebands was observed using a tapered undulator. The experiment is in good agreement with predictions using the MEDUSA simulation code.

Summary Background and objective: Endothelial progenitor cells (EPCs) contribute to postnatal neovascularization, thus promoting wide interest in their therapeutic potential in vascular injury and prevention of their dysfunction in cardiovascular diseases. Cleaved high molecular weight kininogen (HKa), an activation product of the plasma kallikrein-kinin system (KKS), inhibits the functions of differentiated endothelial cells including in vitro and in vivo angiogenesis. In this study, our results provided the first evidence that HKa is able to target EPCs and inhibits their tube forming capacity. Methods and results: We determined the effect of HKa on EPCs using a three-dimensional vasculogenesis assay. Upon stimulation with vascular endothelial growth factor (VEGF) alone, EPCs formed vacuoles and tubes, and differentiated into capillary-like networks. As detected by gelatinolytic activity assay, VEGF stimulated secretion and activation of matrix metallopeptidase 2 (MMP-2), but not MMP-9, in the conditioned medium of 3D culture of EPCs. Specific inhibition or gene ablation of MMP-2, but not MMP-9, blocked the vacuole and tube formation by EPCs. Thus, MMP-2 is selectively required for EPC vasculogenesis. In a concentration-dependent manner, HKa significantly inhibited tube formation by EPCs and the conversion of pro-MMP-2 to MMP-2. Moreover, HKa completely blocked the association between pro-MMP-2 and alphavbeta3 integrin, and its inhibition of MMP-2 activation was dependent on the presence of alphavbeta3 integrin. In a purified system, HKa did not directly inhibit MMP-2 activity. Conclusions: HKa inhibits tube forming capacity of EPCs by suppression of MMP-2 activation, which may constitute a novel link between activation of the KKS and EPC dysfunction.
The spatial profiles of fluid flow velocity in transparent glass and turbid collagen conduits are measured by optical Doppler tomography (ODT). The flow velocity at a discrete user-specified spatial location in the conduit is determined by measurement of the Doppler shift of backscattered light from microspheres suspended in the flowing fluid. Experimental data and theoretical calculations are in excellent agreement. ODT is an accurate method for the characterization of high-resolution fluid flow velocity.

Abstract Background Skin cancer surgery is usually performed on the face, and more specifically on and around the midfacial apertures. Each defect generated by the exeresis of a face tumor can be repaired by various advancement, rotation or transposition flaps techniques. Therefore the choice of the closure axis of a defect and its cicatricial and orificial consequences is decisive. Results The closure of a defect is usually made by symmetrically suturing its edges, across the incision axis according to the rule of halves. However, the closure axis of a defect is intentional and characterized by the subcutaneous suture axis which determines the induced tension orientation, and thus the possible displacement of the aperture free margins. The horizontal stretching principle guarantees the lack of impact on the 3 major apertures of the midfacial frame: eye, nostril and mouth. Conclusions This biomechanical concept is decisive to repair midfacial defect with functional and aesthetic results. It also provides objective arguments for the reparative techniques prioritization and the ability to codify those to be recommended as first-line treatment in the surgical management of the face cutaneous tumours.
Aim: To introduce a small-incision technique for fascia lata (FL) harvesting for the frontalis suspension blepharoptosis procedure. Technique and Methods: A skin incision was made along a line between the lateral condyle of the tibia and the anterior superior iliac crest, starting 4-5 cm above the knee and extending upward 2-2.5 cm. Approximately 8 cm superior to the first incision, a second skin incision was made with the same length. The FL was dissected from the subcutaneous tissue from 1 cm above the superior border of the upper incision to 1 cm below the inferior border of the lower incision. A 15 mm x 5-10 mm strip of FL was excised. The fascial defect was left open. Subcutaneous and deep layers were closed with three 4- plain catgut sutures and the skin was closed with subcuticular 5- prolene sutures. Results: The technique was used in 22 patients from 4 to 47 years of age (mean: 18.29) for 34 frontalis sling procedures. Mean follow-up time was 6.17 (3-16) months. Wound hematoma (1/22, 4.5%), wound discharge (2/22, 9%), pain at rest (100%, for up to 4 days), pain on walking (20/ 22, 90%; for up to 3 weeks), and limping (13/22, 59.1%; for up to 7 days) were the main postoperative complications. No significant skin scar was observed and none of the patients needed scar revision. Conclusion: The small-incision FL harvesting procedure is a good alternative method when the FL stripper is not available.

Mucous cysts are common problems seen by hand surgeons. Surgical excision of symptomatic cysts is the most commonly accepted treatment. Removal of large mucous cysts often requires simultaneous flap coverage or skin grafting for the resulting defect. We present the use of a dorsal advancement flap to permit excellent skin coverage after cyst excision with a tension-free closure.

We performed extrapleural pneumonectomy (EPP) with combined resection of the diaphragm and pericardium via a lower door open (LDO) thoracotomy to treat right malignant pleural mesothelioma (MPM) in a 57-year-old man. Specifically, we extended the standard posterolateral thoracotomy skin incision along the anterior costal arch, and performed the thoracotomy by cutting into the 6th to 9th costal cartilage. The resulting defect of the diaphragm and pericardium were reconstructed with a reversed latissimus dorsi (LD) muscle flap and a fascia lata graft, respectively. The patient had an uneventful postoperative course without dyspnea or dysfunction of the extremities. The LDO thoracotomy provided a good operative field, especially for the costo- and cardiophrenic angles, allowing a complete resection of the diaphragm to be performed easily. Furthermore, the reversed LD muscle flap and fascia lata graft proved to be ideal autologous materials for reconstruction of both the diaphragm and the pericardium.
The efficiency was studied of vascularized tissue complexes in 346 cancer patients with extensive facial injuries to the head and neck who had undergone combined treatment. Free microsurgical autotransplantation was carried out in 7 (2%) patients, deltapectoral graft--151 (44%), sternocleidomastoid myocutaneous flap--39 (11%), pectoralis major flap--10 (3%), bi- and tri-lobed flap--55 (16%), temporal musculoperiosteal flap--25 (7%), cheek flap--24 (6.9%), thoraco-dorsal axillary flap--24 (6.9%), frontal flap--6 (1.7%), free-flap transfer--5 (1.5%). Although most vascularized tissue complexes were placed in previously irradiated areas, primary engraftment was reported in 249 (72%) patients, while peripheral or partial necrosis in distal part of flap- in 97 (28%). Good cosmetic and functional results were obtained in 298 (86%) patients who considered themselves cured.

Replacement of defect of the upper third of the ear consequent to a traffic accident was successfully performed using modified Antia-Buch technique. Creation of wider and longer skin-cartilage flaps and their increased rotation allowed formation of the upper edge of the ear without tension and postoperative complications. Although the repaired ear is a bit smaller to attain adequate relief and matching color, the use of this method achieved a satisfactory esthetic result.
