The Comparison of Scars in Breast Implantation Surgery with Inframammary Fold Incision Versus Axillary Incision: A Prospective Cohort Study in Chinese Patients

BACKGROUND

A prospective cohort study was developed to compare the surgical scars in the axilla and the inframammary fold at short-, medium- and long-term time periods after surgery.

METHODS

Patients who underwent primary breast augmentation with implants in our department were divided into two groups based on the incision location they chose and were followed up for scar assessment at 1 month, 6 months and 12 months post-surgery from June 2012 to March 2016. Each scar was evaluated by the Vancouver Scar Scale (VSS) and patient satisfaction score. The data were analyzed with Wilcoxon rank-sum tests, Cochran-Armitage trend tests and Fisher's exact probability tests based on the data type.

RESULTS

One hundred and sixty-three patients were completely investigated three times. Ninety-four patients underwent breast augmentation surgeries with implants through axillary approaches and 69 patients through IMF approaches. At 1 month after surgery, the median total VSS score was 6 in the axillary incision group and 4 in the IMF group, with statistically significant differences (P < 0.05). Larger proportions of high scores in terms of vascularity and height were found in the axillary incision group (P < 0.05). At 6 months after surgery, the median total VSS score was 4 in the axillary incision group and 3 in the IMF group, with statistical significance (P < 0.05). The axillary group still had a larger proportion of high scores in terms of vascularity and height than that of the IMF group (P < 0.05). At 12 months after surgery, the median total VSS score was 2 in both groups. The median patient satisfaction score was 9 in both groups. No significant differences were noted in the total VSS and patient satisfaction scores between the two groups. However, the axillary group had a larger proportion of high scores in terms of vascularity and low scores in terms of pliability.

CONCLUSIONS

The total VSS score for the axillary incision group was significantly higher than that for the IMF incision group one and 6 months after surgery, mainly on the subscales of vascularity and height. At 12 months after surgery, the total VSS scores were not different between the two groups, and patients with both kinds of incisions were highly satisfied with scar appearance. The research confirmed that the scars at two locations can achieve comparable appearance in the long term after surgery.

Accuracy of interferon-γ-induced protein 10 for diagnosing latent tuberculosis infection: a systematic review and meta-analysis

BACKGROUND

Effective diagnostic methods for detecting latent tuberculosis infection (LTBI) are important for its eradication. A number of studies have evaluated the use of interferon-γ-induced protein 10 (IP-10), which is elevated after tuberculosis infection, as a biomarker for LTBI, but conclusive results regarding its effectiveness have not been reported.

OBJECTIVES

Our objective was to assess the diagnostic value of IP-10 for LTBI.

DATA SOURCES

We searched the PubMed, Embase, the Cochrane Library and Web of Science databases to find eligible studies.

STUDY ELIGIBILITY CRITERIA

We included cohort, case-control and cross-sectional studies that evaluated IP-10 in LTBI participants in comparison with tuberculin skin tests (TST) and interferon-γ release assays (IGRA).

PARTICIPANTS

Individuals with LTBI and uninfected participants.

INTERVENTIONS

IP-10 (index test) compared with TST and IGRA (reference standard) for diagnosing LTBI.

METHODS

PubMed, Embase, the Cochrane Library, and Web of Science databases were searched up to June 2018. A hierarchical summary receiver operating characteristic (HSROC) model was used to evaluate the pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and HSROC curve for the diagnostic efficiency of IP-10.

RESULTS

Twelve studies including 1023 participants and 1122 samples were included. The overall pooled sensitivity was 0.85 (95% CI 0.80-0.88), specificity was 0.89 (95% CI 0.84-0.92), PLR was 7.55 (95% CI 5.20-10.97), NLR was 0.17 (95% CI 0.13-0.22) and DOR was 44.23 (95% CI 28.86-67.79), indicating a high accuracy for diagnosing LTBI. Based on a meta-regression analysis, high-burden countries, study design, IP-10 method, reference standard and the IP-10 cut-off could not explain the heterogeneity (p >0.05).

CONCLUSIONS

Our results suggested that IP-10 is a promising biomarker for the diagnosis of LTBI.

[Analysis on the epidemiological features of human brucellosis in northern and southern areas of China, 2015-2016]

Different epidemiological features of human brucellosis appeared in both northern and southern areas of China. The disease was seen endemic in the northern and dispersal in the southern provinces. Appropriate strategies for brucellosis prevention and control should be developed, according to the different epidemiological characteristics in the northern or southern areas.

Efficacy and safety of acellular dermal matrix in diabetic foot ulcer treatment: A systematic review and meta-analysis

BACKGROUND

Diabetic foot ulcer(DFU) is a chronic, refractory disease in need of multidisciplinary endeavour, miscellaneous strategies have been adopted to address this annoying issue, including acellular dermal matrix(ADM)/negative pressure wound therapy/standard of care (SOC) etc. However, consensus has not been reached. As a promising procedure, the efficacy and safety of ADM remains controversial. We therefore performed a meta-analysis of randomized controlled trials (RCTs) to compare the efficacy and safety of acellular dermal matrix to standard of care in DFU.

METHODS

Databases, including Pubmed, Medline, Embase and Cochrane library were searched to identify RCTs comparing ADM to SOC in DFU patients. The outcomes mainly included complete wound healing, mean time to heal and adverse events.

RESULTS

A total of 632 DFU patients from 6 RCTs were subjected to meta-analysis. The results showed that compared with the merely SOC, the complete healing rate in ADM group was higher both at 12 weeks [risk ratio (RR) 2.31, 95% confidence interval (CI) 1.42 to 3.76] and 16 weeks [RR 1.57, 95% CI 1.28 to 1.93]. The mean time to complete wound healing was shorter in ADM group [MD = -2.98, 95% CI: -5.15 to -0.82]. The occurrence of adverse event in both groups showed no significant difference [RR 0.98, 95%CI 0.58 to 1.67].

CONCLUSION

Compared with standard of care, acellular dermal matrix may accelerate the healing velocity of uninfected, non-ischemic, full-thickness diabetic foot ulcer. Acellular dermal matrix showed superiority compared with standard of care alone, while generating no more complications.

What is the Optimal Range of Medial Pocket Dissection in Breast Augmentation? An Anatomical Study of Chinese Women

BACKGROUND

The range of the medial dissection forbidden zone, defined as the no-touch zone in this study, is of great importance in breast augmentation. Currently, 30 mm of the no-touch zone is marked and the pocket dissection does not pass medial to this zone, which lacks anatomical evidence. This study aimed to determine the optimal range of the no-touch zone in breast augmentation by precisely locating relevant anatomical structures.

METHODS

Preoperative multidetector-row CT angiography (MDCTA) was performed in 36 Chinese female patients who were to receive breast reconstruction. The MDCTA data were used to measure the healthy side's horizontal distance from the cutaneous perforators of the internal thoracic artery to the midline, from the sternal origin of the pectoralis major to the midline, from the sternal border to the midline, at the 2nd to 5th intercostal spaces in the subpectoral plane.

RESULTS

All the target tissues were identified in MDCTA data. Mean distances from cutaneous perforators of the internal thoracic artery to the midline of the 2nd to 5th intercostal spaces were 19.66 ± 4.08, 20.37 ± 3.88, 21.00 ± 3.63, and 21.35 ± 4.80 mm; and that from the sternal origin of pectoralis major to midline were 5.00 ± 4.01, 4.83 ± 2.85, 11.67 ± 5.35, and 19.19 ± 7.10 mm; and that from the sternal border to the midline were 12.48 ± 1.70, 14.02 ± 2.05, 13.52 ± 2.91, and 4.68 ± 4.44 mm.

CONCLUSIONS

Most of perforators of the internal thoracic arteries are disrupted in the current surgical process, indicating that the restrictive factor that affects the range of the no-touch zone is the sternal origin of the pectoralis major, rather than the cutaneous perforators. The range of the no-touch zone can be minimized to 20 mm in the 2nd and 3rd intercostal spaces, and can be 30 mm in the 4th intercostal space. However, surgeons should be more cautious to avoid disrupting the origin of the pectoralis major when dissecting the pocket of the 4th and 5th intercostal spaces.

Scar Assessment After Breast Augmentation Surgery with Axillary Incision versus Inframammary Fold Incision: Long-Term Follow-Up in Chinese Patients

BACKGROUND

The inframammary fold (IMF) incision is widely used in Western countries for breast augmentation surgery, whereas the axillary incision is the dominant approach used in China, because many Chinese surgeons believe that the Asian population has a higher risk of developing hypertrophic scars. However, comparative data of scar assessment through different incisions in Chinese patients are scarce. The aims of the study were as follows: (1) to evaluate the outcomes of scar assessment using the Vancouver scar scale (VSS), combined with patient satisfaction scoring, in the scar assessment after breast augmentation surgery; (2) to compare the long-term cosmetic effects of surgical scars between axillary and IMF incisions.

METHODS

Consecutive patients coming to our department for follow-up care at least 1 year after primary breast augmentation surgeries with axillary and IMF incisions between January 1, 2014 and December 31, 2014 were included in the research. Internal consistency, inter-rater reliability, and convergent validity were examined for the VSS and patient satisfaction scoring. The baseline characteristics and scar scores were tested using the Mann-Whitney U-test and Student's t test between the two groups.

RESULTS

Sixty-one patients underwent implantation surgeries through the axillary incisions, and 17 patients through the IMF incisions. There were no significant differences in age, follow-up time, body mass index, implant volume, or implant projection between groups. Reliability and validity of the VSS and patient satisfaction scoring were satisfactory. The scores of pigmentation were higher in the IMF group than those in the axilla group with statistical significance (P < 0.05). The scores of other subscales, overall VSS scores, and patient satisfaction were not statistically significant. The scars were significantly longer in the axilla group compared with the IMF group (P < 0.05).

CONCLUSIONS

The VSS combined with patient satisfaction scoring constitutes an effective tool to evaluate incision scars after augmentation mammaplasty. Scars in the axilla and IMF can achieve comparable cosmetic effects and patient satisfaction in Chinese women. Chinese patients with proper indications can receive breast augmentation surgery through the IMF incision, with fewer risks and less trauma, and get satisfactory scar appearance as through the axillary incision.

Neurodevelopmental delay with critical congenital heart disease is mainly from prenatal injury not infant cardiac surgery: current evidence based on a meta-analysis of functional magnetic resonance imaging

OBJECTIVE

No consensus has been reached regarding whether brain injury related to congenital heart disease (CHD) is caused by infant cardiac surgery and/or prenatal injury resulting from the CHD. We performed this meta-analysis to identify the likely cause of neurodevelopmental delay in CHD patients.

METHODS

We carried out a literature search without language restriction in December 2013, retrieving records from PubMed, EMBASE, the Cochrane Library and the World Health Organization trials center, to identify studies applying functional magnetic resonance imaging (fMRI) evaluation of brain function before surgery and, in some cases, after surgery (both immediate term and short term postoperatively). The preoperative and postoperative fMRI results were extracted, and meta-analysis was performed using Revman 5.1.1 and STATA 11.0, according to the guidelines from the Cochrane review and MOOSE groups.

RESULTS

The electronic search yielded 937 citations. Full text was retrieved for 15 articles and eight articles (nine studies) were eligible for inclusion: six studies (n = 312 cases) with fMRI analysis before surgery and three (n = 36 cases) with complete perioperative fMRI analysis. The overall average diffusivity of CHD cases was significantly higher than that of controls, with a summarized standard (std) mean difference of 1.39 (95% CI, 0.70-2.08), and the fractional anisotropy was lower in CHD cases, with a summarized mean difference of -1.43 (95% CI, -1.95 to -0.91). N-acetylaspartate (NAA)/choline (Cho) for the whole brain was significantly lower in CHD cases compared with healthy ones, while lactate/Cho was significantly higher in CHD cases. Immediate term postoperatively, significant changes in NAA/creatine and NAA/Cho, relative to preoperative values, were found. However, the difference did not persist at the short-term follow-up.

CONCLUSION

This meta-analysis suggests that the delay in neurological development in newborns with CHD is due mainly to prenatal injury, and cardiac surgery might lead to mild brain injuries postoperatively, but fMRI shows recovery within a short period.

Chinese women's preferences and concerns regarding incision location for breast augmentation surgery: a survey of 216 patients

BACKGROUND

The axillary approach is the dominant incision used in China for breast augmentation. Systematic preoperative education regarding incision locations for breast augmentation is scarce in China. In this study, we surveyed Chinese patients to ascertain their preferences and concerns for incision location based on a comprehensive understanding of different incisions.

METHODS

We used a literature review, patient interviews, and expert panels to develop the preoperative education material and questionnaire regarding different incision locations. The respondents were requested to choose one incision location before and after they received the preoperative education. Their initial choices and final decisions as well as the reasons for these choices were recorded and analyzed. Multinomial logistic regression was preformed to analyze the affecting factors on the incision choice.

RESULTS

A total of 216 Chinese women participated in the study between 2012.5 and 2014.1. Initially, 176 (81.48%) women chose axillary incision, 27 (12.50%) chose periareolar incision, and 13 (6.02%) chose inframammary fold (IMF) incision. After they received preoperative education on incisions, the axillary and periareolar approaches decreased to 117 (54.17%) and 13 (6.02%), respectively, while IMF increased to 86 (39.81%). The easily hidden scar (43.98%), lower capsular contracture rate (23.15%), and lower possibility of injury to the breast parenchyma (17.13%) ranked as the top 3 reasons for the incision choice. Patients with a preoperative cup size of AA were 12.316 times more likely to choose the axillary approach relative to the IMF approach compared with those with a B cup (P = 0.044; 95% confidence interval [CI] 1.069-141.923). For each one-unit increase in BMI, the odds that a patient would choose the axillary versus the periareolar approach decreased by 32.4% (P = 0.049; 95% CI 0.457-0.999).

CONCLUSIONS

The systematic and objective preoperative education material and questionnaire regarding different incision locations helped the Chinese patients make truly informed decisions and express their personal requirements. The axillary approach was the first option for more than half of Chinese women mainly because an easily hidden scar was considered the primary concern during the decision-making process. The patients with a low BMI and a small preoperative breast cup size were more likely to choose an axillary incision. However, a considerable number of Chinese women would choose the IMF incision and value its superiority in terms of a lower capsular contracture rate, less tissue trauma, and lower possibility of injury to the breast parenchyma.

[Relationship between serum histamine levels and ST-segment resolution in patients with acute myocardial infarction treated with primary percutaneous coronary intervention]

OBJECTIVE

To investigate the dynamic changes in serum histamine levels and their association with ST-segment resolution in patients with acute ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI).

METHODS

A total of 84 consecutive STEMI patients who received primary PCI were enrolled in this study. The dynamic changes in serum histamine levels were observed from before PCI to 1 week after PCI. Factors associated with ST-segment resolution were identified by multivariate regression analysis.

RESULTS

The serum histamine levels of STEMI patients decreased during the first week after PCI. Multivariate regression analysis showed that the factors associated with ST-segment resolution 2 h after PCI were: the histamine level 2 h after PCI (r=-0.361, P=0.001), pain to balloon time, infarct related artery, and thrombolysis in myocardial infarction (TIMI) flow grade after PCI.

CONCLUSION

The higher histamine level 2 h after PCI was independently associated with poor myocardial reperfusion in STEMI patients.

A prospective study of breast dynamic morphological changes after dual-plane augmentation mammaplasty with 3D scanning technique

Background

The dual-plane technique has been widely used in augmentation mammaplasty procedures. However, there are some concerns about aesthetic contour maintenance for long time after muscle releasing. This study aims to track and analyze breast dynamic morphological changes after dual-plane breast augmentation with three-dimensional (3D) scanning technique.

Methods

Thirteen dual-plane anatomic implant augmentation patients underwent 3D scanning preoperatively (pre-OP) and postoperatively in four time points (1 month: post-1M, 3 months: post-3M, 6 months: post-6M and 12 months: post-12M). The linear distance, breast projection, nipple position, breast volume and breast surface area were measured and analyzed on the 3D models over time.

Results

Compared with post-12M, no significant differences were found in distances of nipple to midline, nipple to inframammary fold and sternal notch to the level of inframammary fold after 6 months in both straight-line distance and its projection on surface. The distances between sternal notch and nipple had no significant difference after post-1M. Breast volume changes had no significant difference after post-3M. The volume and area percentage of upper pole decreased while the lower pole’s increased gradually. The surface showed no significant changes after post-1M. The changes of breast projection had no significance after post-1M either. The nipple moved 1.0±0.6 cm laterally(X axis), 0.6±0.7 cm upward(Y axis) and 2.3±1.1 cm anteriorly (Z axis) at post-12M, and the differences were not significant after post-1M.

Conclusions

3D scanning technique provides an objective and effective way to evaluate breast morphological changes after augmentation mammaplasty over time. Dual-plane augmentation optimizes breast shape especially in the lower pole and maintains stable aesthetic outcome during the 12 months follow-up. Most of the contour changes and the interadaptation with the implant have completed 6 months after operation. Therefore, 6 months could be chosen as a relatively stable observing period in the assessment of postoperative outcomes of dual-plane breast augmentation.

The neuroprotective role and mechanisms of TERT in neurons with oxygen-glucose deprivation

Telomerase reverse transcriptase (TERT) is reported to protect neurons from apoptosis induced by various stresses including hypoxia-ischemia (HI). However, the mechanisms by which TERT exerts its anti-apoptotic role in neurons with HI injury remain unclear. In this study, we examined the protective role and explored the possible mechanisms of TERT in neurons with HI injury in vitro. Primary cultured neurons were exposed to oxygen and glucose deprivation (OGD) for 3h followed by reperfusion to mimic HI injury in vivo. Plasmids containing TERT antisense, sense nucleotides, or mock were transduced into neurons at 48h before OGD. Expression and distribution of TERT were measured by immunofluorescence labeling and western blot. The expression of cleaved caspase 3 (CC3), Bcl-2 and Bax were detected by western blot. Neuronal apoptosis was measured with terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL). The mitochondrial reactive oxygen species (ROS) were measured by MitoSOX Red staining. Fluorescent probe JC-1 was used to measure the mitochondrial membrane potential (ΔΨm). We found that TERT expression increased at 8h and peaked at 24h in neurons after OGD. CC3 expression and neuronal apoptosis were induced and peaked at 24h after OGD. TERT inhibition significantly increased CC3 expression and neuronal apoptosis after OGD treatment. Additionally, TERT inhibition decreased the expression ratio of Bcl-2/Bax, and enhanced ROS production and ΔΨm dissipation after OGD. These data suggest that TERT plays a neuroprotective role via anti-apoptosis in neurons after OGD. The underlying mechanisms may be associated with regulating Bcl-2/Bax expression ratio, attenuating ROS generation, and increasing mitochondrial membrane potential.

A minimally invasive gradual traction technique for inverted nipple correction

BACKGROUND

An inverted nipple affects not only the aesthetic appearance of the breast but also breastfeeding. Most surgical procedures can cause injury to normal lactiferous ducts and sensory dysfunction. The authors present a simple, safe, and minimally invasive technique for treating inverted nipples.

METHODS

A distracter was made using the distal end of a 5- or 10-ml disposable syringe. The length was 1.3-1.5 cm, and pinholes with a diameter of 1 mm were punctured at 3, 6, 9, and 12 o'clock at the apex of the distracter. The inverted nipple was pulled out, and two steel wires with a diameter of 0.6 mm were crossed through the nipple base and fixed to the external distracter. After surgery, the wires were tightened once per month. According to the severity of the nipple inversion, the distracter was removed after 4-6 months of traction.

RESULTS

This method was used to correct 604 inverted nipples of 310 patients. The follow-up period ranged from 6 months to 2 years. No complications associated with surgery such as infection, depigmentation, sensory disturbance, or nipple necrosis occurred. The great majority of the patients (95.8 %) were satisfied with the aesthetic results.

CONCLUSIONS

The described technique is minimally invasive, simple, safe, reliable, and low in cost. Satisfying aesthetic results can be achieved without destroying breastfeeding function or nipple sensation.

An innovative method for intraoperative shaping and positioning of the nipple-areola complex in reduction mammaplasty and mastopexy

Issues of hypertrophic circumareolar scars and malpositioning or irregularity of the nipple-areola complex (NAC) are frequently associated with breast reduction or mastopexy techniques that rely on an ample excision of skin around the areola, either alone or associated with a vertical incision. To avoid such problems, many efforts have been made to improve the accuracy of preoperative marking for the future NAC. However, the correct design and position of the NAC may be difficult to achieve for the patient at the end of the procedure after closure of the skin incisions. This article describes a novel, simple, and effective method for intraoperative shaping and positioning of the NAC. The described method is based on using a specially designed surgical instrument to determine the best position, diameter, shape, and configuration of a new NAC. This study aimed to demonstrate the efficacy of this method to reduce the common complications of the periareolar region in reduction mammaplasty and mastopexy.
