Relationship Between Brassiere Cup Size and Shoulder-Neck Pain in Women

There are very few reports in regard to relationship between breast size and shoulder-neck pain. The purpose of this study is to examine the correlations among breast size, brassiere cup size, and moment-in-time reporting of shoulderneck pain in a group of adult women. Three hundred thirty nine female volunteers from the hospital staff answered the questionnaire. Breast size, brassiere cup size, and shoulder-neck pain were self-reported by each participant. The relationship among breast size, brassiere cup size and shoulder-neck pain was investigated. Spearman’s test showed no significant relationship between shoulder-neck pain and brassiere cup size. However, after participants were classified into two groups (small brassiere cup size and large brassiere cup size with 219 and 120 participants, respectively), there was a significant positive correlation between shoulder-neck pain and large brassiere cup size (p<0.05). There was no significant relationship between shoulder-neck pain and breast size. In conclusion, large brassiere cup size is an important cause of shoulder-neck pain

Platelet lysate-based pro-angiogenic nanocoatings

Human platelet lysate (PL) is a cost-effective and human source of autologous multiple and potent pro-angiogenic factors, such as vascular endothelial growth factor A (VEGF A), fibroblast growth factor b (FGF b) and angiopoietin-1. Nanocoatings previously characterized were prepared by layer-by-layer assembling incorporating PL with marine-origin polysaccharides and were shown to activate human umbilical vein endothelial cells (HUVECs). Within 20 h of incubation, the more sulfated coatings induced the HUVECS to the form tube-like structures accompanied by an increased expression of angiogenicassociated genes, such as angiopoietin-1 and VEGF A. This may be a cost-effective approach to modify 2D/3D constructs to instruct angiogenic cells towards the formation of neo-vascularization, driven by multiple and synergistic stimulations from the PL combined with sulfated polysaccharides. Statement of Significance The presence, or fast induction, of a stable and mature vasculature inside 3D constructs is crucial for new tissue formation and its viability. This has been one of the major tissue engineering challenges, limiting the dimensions of efficient tissue constructs. Many approaches based on cells, growth factors, 3D bioprinting and channel incorporation have been proposed. Herein, we explored a versatile technique, layer-by-layer assembling in combination with platelet lysate (PL), that is a cost-effective source of many potent pro-angiogenic proteins and growth factors. Results suggest that the combination of PL with sulfated polyelectrolytes might be used to introduce interfaces onto 2D/3D constructs with potential to induce the formation of cell-based tubular structures.The research leading to these results has received funding from European Union's Seventh Framework Program (FP7/2007-2013) under grant agreement na REGPOT-CT2012-316331 - POLARIS and FP7-KBBE-2010-4-266033 - SPECIAL.

Is Clipping Superior to Cauterization in the Treatment of Palmar Hyperhidrosis?

Background Endoscopic thoracic sympathectomy has been accepted as the most effective treatment for palmar hyperhidrosis (PH). However, there is a debate regarding the surgical techniques in terms of effectiveness, recurrence, and reversibility. In this study, sympathetic chain disruptions were compared in terms of whether the clipping or ablation technique had an effect on the long-term outcomes of patients who underwent thoracic sympathectomy for primary PH. Patients and Methods All patients who underwent video-thoracoscopic sympathectomy for PH between May 2008 and October 2011 were included. Single-port bilateral sympathectomy was performed depending on the sweat distribution. As a standard approach, rib-based terminology was used to describe the blockade level of the sympathetic ganglia, and single-level R3 sympathectomy (between R3 and R4) was performed in all patients. The type of sympathectomy was changed. Monopolar electrocautery was first performed and 5-mm clips were then used for nerve disruption. Both techniques were evaluated and compared in terms of effectiveness, reversibility, and recurrence. Results Cauterization of the sympathetic chain was applied in 28 (47%) (Group A) patients and clipping in 32 (53%) patients (Group B). CH was the most common adverse effect and was observed in 43 (71.6%) patients (Group A, 71.4%; Group B, 71.8%; p = 0.8). The success rate was 93% for Group A and 100% for Group B (p = 0.15). The satisfaction rate for Group A was 83% and for Group B was 86% (p = 0.77). In Group A two patients (7%), and in Group B three patients (9%) requested reversibility because of severe compensatory hyperhidrosis. Overly dry hands were the other most common side effect and were identified in 12 (25%) patients. Recurrences were observed in 11 patients in Group A and 4 patients in Group B (19 vs. 6%; p = 0.01). The mean follow-up time was 33 +/- 10.5 months (range, 13-53 months). Conclusion Both clipping and cauterization are highly effective for the treatment of PH. The methods are comparable in terms of effectiveness and side effects despite the fact that the recurrence rate was higher in the cauterization group. Potential reversibility of compensatory sweating was not observed in our series. Identification of ideal candidates for surgery and education of patients about the permanent side effects of sympathectomy might make these techniques more convenient

Chondromyxoid Fibroma of the Sternum in a 63-Year-Old Woman

Primary chondromyxoid fibroma is a benign bone tumor. Its localization in the sternum is quite rare; we found only 6 relevant reports. We report our diagnosis and treatment of a chondromyxoid fibroma in the sternum of a 63-year-old woman. The patient underwent subtotal sternectomy and chest-wall reconstruction with use of a titanium rib bridge system and Prolene mesh. The patient's clinical course was uneventful, and she had no local recurrence 41 months postoperatively. Our review herein of the 6 previous cases reveals that our patient is the oldest thus far to have been diagnosed with a sternal chondromyxoid fibroma
