A Systematic Review of Outcomes and Patient Satisfaction Following Surgical and Non-surgical Treatments for Hair Loss

INTRODUCTION

This systematic review aims to examine surgical and non-surgical treatments and identify those procedures that are most effective in terms of patient satisfaction.

MATERIALS AND METHODS

A systematic review protocol was developed a priori in accordance with the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses-Protocols (PRISMA-P) guidelines. The search was conducted in accordance with the PRISMA guidelines, the Cochrane handbook. A multistep search of the PubMed, MEDLINE, Embase, PreMEDLINE, Ebase, CINAHL, PsycINFO, and Cochrane databases was performed to identify studies on hair loss causes and hair loss treatment with different surgical and non-surgical techniques RESULTS: Our search generated a total of 781 articles; 646 studies were excluded based on the content of the abstracts, and an additional 105 studies were excluded based on the content of the complete article. We performed a review of the 30 remaining studies, which had sufficient data for inclusion, and met all the aforementioned inclusion criteria. Of the 30 studies, four were about minoxidil, four about finasteride, two about dutasteride, three about phototherapy, six about platelet-rich plasma injection, four about follicular unit transplantation technique, six about follicular unit extraction technique, and one about patient satisfaction following surgical treatment without a specified surgical technique. Only three studies used a patient-reported outcome measurement.

CONCLUSIONS

Our study is the first comprehensive systematic review of hair loss, looking at the problem from different points of view, and focusing on finding the best solution for the patient. In the literature, there is currently no algorithm for the management of patients who go to a plastic surgeon for a solution to the problem of hair loss.

Treatment of Severe Gynecomastia After Massive Weight Loss: Analysis of Long-Term Outcomes Measured with the Italian Version of the BODY-Q

INTRODUCTION

The objectives of this study are: (1) comparison of long-term outcomes after correction of severe gynecomastia using different techniques; (2) apply the Italian version of the BODY-Q; (3) present the role of intercostal perforator flap (ICAP) after massive weight loss for correction of severe gynecomastia.

MATERIALS AND METHODS

Between January 2008 and March 2016, we performed surgical correction of bilateral severe gynecomastia in 80 men (160 breasts) following massive weight loss. Patients answered the Italian version of BODY-Q postoperative module. All patients had experienced substantial weight loss (> 30 kg), presented with bilateral severe tissue ptosis of the breast, follow-up of almost 2 years and had a good understanding of the Italian language, and signed consents were included in the study. The sample was studied about age, BMI, comorbidity, bariatric surgical procedure, follow-up, type of post-bariatric surgical procedure, complications and secondary procedures.

RESULTS

We performed 487 severe gynecomastia corrections from 2008 to 2016; 80 patients adhered to the inclusion criteria and formed our study group. This cross-sectional study compared three cohorts: 52 access using a circumareolar scar, 18 with an inframammary fold scar, 10 with an inframammary fold scar using intercostal perforator flaps. There were 16 secondary procedures in group one, 2 in group two and 1 in group three. We compared the secondary procedures of group 1 with the other groups, and we obtained a significant difference with a P = 0.04. The mean patient age was 36.5 years, and the average body mass index was 27.5 kg/m² at the time of surgical correction of gynecomastia. From the BODY-Q analysis, the group of patients undergoing adenomammectomy with inframammary fold scar using intercostal perforator flaps has achieved significantly better results regarding the satisfaction with chest, psychosocial function, satisfaction with outcome and better body image.

CONCLUSIONS

This is the first study that used the BODY-Q to analyze the correction of severe gynecomastia following massive weight loss with long-term results. The use of this patient-reported outcome measure underlined that the intercostal artery perforator flap, used in the correction of severe gynecomastia following massive weight loss, is a safe and effective technique with good outcomes and high patient satisfaction.

Analysis of Symmetry Stability Following Implant-Based Breast Reconstruction and Contralateral Management in 582 Patients with Long-Term Outcomes

INTRODUCTION

This study aimed to analyse the long-term outcomes following breast reconstruction and contralateral management to evaluate the stability of breast symmetry and patient satisfaction.

MATERIALS AND METHODS

The study population consisted of women who had undergone implant-based monolateral breast reconstruction and contralateral management. Patients answered the BREAST-Q reconstruction module. Two reviewers analysed the post-operative outcomes of the patients included and compiled the Kroll Scale. Patients were divided into three groups: implant-based contralateral management, breast reduction and mastopexy. The Fisher's exact test was applied to the results.

RESULTS

From the BREAST-Q analysis, the group of patients undergoing contralateral breast augmentation achieved significantly better results regarding the ability to wear clothing (p ≪ 0.001), symmetry (p ≪ 0.001), psychosocial well-being (p ≪ 0.001) and physical well-being (p ≪ 0.001). From the analysis of the Kroll Scale, the group of implant-based contralateral management received the highest score for symmetry (p ≪ 0.001), shape (p ≪ 0.001) and aesthetic result overall (p ≪ 0.001).

CONCLUSIONS

This study was the first to use BREAST-Q to analyse the stability of breast symmetry following breast reconstruction with long-term results. The implant-based contralateral management was the most effective procedure for achieving a stable and lasting result to obtain the high satisfaction of patients.

Mastopexy on Reconstructed Breast Following Massive Weight Loss: An Innovative Technique Using Dermo-Capsular Flaps

BACKGROUND

We have developed a dermo-capsular flap mastopexy technique for patients who have experienced massive weight loss after breast reconstruction. The aim of this technique is to lift the inframammary fold, adequately cover the implant, and remove excess skin, elevating the breast and obtaining symmetry with the contralateral breast.

METHODS

Between January 2014 and February 2017, we performed this technique on 20 women who were candidates for second-stage breast reconstruction following nipple-sparing mastectomy. All patients had experienced substantial weight loss (> 15 kg) and presented with ptosis after first-stage reconstruction.

RESULTS

There were 8 patients with bilateral reconstruction following bilateral mastectomy (4 with bilateral nipple-sparing mastectomy). There were 12 patients with unilateral mastectomy, all with contralateral breast ptosis treated by augmentation via inverted-T mastopexy (n = 7) or crescent mastopexy (n = 5). The average lift of the nipple-areola complex was 5 cm (range 2-8 cm). The average follow-up was 12 months (range 4-36 months). Two patients had complications, including partial wound dehiscence (in a heavy smoker) and recurrence of breast asymmetry.

CONCLUSIONS

Implant breast reconstruction after massive weight loss is still possible even in the setting of thin, ptotic, and anelastic breast tissue. Our inverted-T dermo-capsular flap mastopexy technique for reconstructed breast is safe and effective with good outcomes and high patient satisfaction.

Management of contralateral breast following mastectomy and breast reconstruction using a mirror adjustment with crescent mastopexy technique

INTRODUCTION

Heterologous breast reconstruction after mastectomy sometimes requires the management of the contralateral breast to achieve symmetric long lasting aesthetic results. Some techniques could be used for the symmetrization of contralateral breast with or without implants as breast augmentation, reduction mammoplasty, mastopexy, with T inverted, J, vertical, periareolar, semi-circular, or axillary scars. The aim of this study is to present the use of crescent mastopexy technique with implants in contralateral adjustment following monolateral breast reconstruction compared with a control group in which patients underwent other contralateral procedures. We used BREAST-Q to evaluate breast perception and patient's satisfaction and surgeon-rated aesthetic outcomes were measured using the Kroll evaluation (a global and itemized aesthetic tool).

MATERIALS AND METHODS

A retrospective study was designed. We enrolled in the study 55 patients who had undergone breast reconstruction with implants and contralateral breast symmetrization procedure at our hospital between 2010 and 2016, and they answered to BREAST-Q postoperative module after almost 1 year from breast reconstruction. The study population consisted of 2 groups of women: patient underwent contralateral adjustment with crescent mastopexy and augmentation and patients underwent other contralateral procedures. Statistical analysis was performed using descriptive and summary statistics to identify a central tendency between the two groups, we applied Fisher's exact test to the results to obtain answers 1 year after the last procedure for the two groups.

RESULTS

This cross-sectional study compared two cohorts in which 55 women underwent monolateral mastectomy and breast reconstruction with contralateral adjustment, 15 of these underwent contralateral crescent mastopexy with augmentation, and 40 (control group) underwent contralateral breast adjustment with other mastopexy and augmentation technique (27 patients underwent T inverted mastopexy, 2 J mastopexy, 6 vertical scar mastopexy, 5 periareolar mastopexy). Nineteen patients suffered of co-morbidities (smoking, autoimmune disease, cardiological, neurological, and dismetabolic). All patients answered the postoperative BREAST-Q reconstruction module almost 1 year from last surgical procedure.

CONCLUSIONS

In patients with a pseudoptosis or mild ptosis of the contralateral breast, crescent mastopexy could be a valid procedure with minimal scars, better symmetry, and global cosmetic results than other procedures. This is the first study which compares crescent mastopexy with augmentation with other mastopexy procedures. Level III: evidence obtained from well-designed cohort or case-control analytic studies, preferably from more than one center or research group.

LEVEL (III)

Evidence obtained from well-designed cohort or case-control analytic studies, preferably from more than one center or research group.

A Systematic Review of Patient-Reported Outcome Measures Following Transsexual Surgery

BACKGROUND

The aims of our study were to identify studies that evaluated patient satisfaction after transsexual surgery, analyze existing questionnaires, and summarize their development, psychometric properties, and content.

METHODS

A systematic review of the English-language literature was performed. Patient-reported outcome measures designed to assess patient satisfaction and quality of life following transsexual surgery were identified. Qualifying instruments were assessed for content and adherence to international guidelines for development and validation.

RESULTS

From 796 articles, 19 studies had sufficient data and met the inclusion criteria. Included were a total of 2299 patients and 17 patient-reported outcome measures: 10 generic instruments that assessed quality of life, 4 specific for female genital or sexual satisfaction, 2 specific for transsexual body image or gender dysphoria, and 1 specific for plastic surgery. The questionnaires were analyzed by reviewers to assess the adherence to the rules of the US FDA and the Scientific Advisory Committee of the Medical Outcomes Trust. We identified 17 individual questionnaires that were included. All measures were limited by either their development, their validation, or their content.

CONCLUSIONS

There is a need for a new self-assessment tool, which should include functional, psychorelational, and cosmetic components, to measure satisfaction and quality of life of patients who have undergone transsexual surgery.

Ten years experience with breast reconstruction after salvage mastectomy in previously irradiated patients: analysis of outcomes, satisfaction and well-being

OBJECTIVE

Reconstruction following mastectomy offers women an opportunity to mollify some of the emotional and aesthetic effects of this devastating disease.

PATIENTS AND METHODS

The authors reviewed the files of 83 patients who underwent immediate postmastectomy reconstruction with tissue expander between January of 2003 and June of 2012 at our hospital. The patients were divided into two groups: Group A (study group) included 30 patients with previous quadrantectomy and radiotherapy who underwent salvage mastectomy after local recurrence; Group B (control group) included 53 patients submitted to primary radical mastectomy. We submitted Breast-Q reconstruction post-operative module to all of our patients.

RESULTS

The median follow-up time for the whole group was 36 months (range = 12-144 months). Between group A and group B, there were no significant differences. In the group A, the median time from RT to reconstruction was 24 months (range = 9-192 months). The overall rate of complications was not similar between the two groups (66.6% vs. 58.5%; p = NS). However, the  major complications occurred mostly in the irradiated group, showing a trend of statistical significance (53.3% vs. 32.0%; p = 0.07). In this group, the occurrence of major complications was not different according to time from RT to reconstruction (p = 0.313). In particularly, patients from the irradiated group (group A) had a significantly higher risk of grade III-IV capsular contracture (relative risk 3.75, p = 0.02) and autologous salvage reconstruction (relative risk 10.4, p = 0.02).

CONCLUSIONS

The results of this study prove that heterologous reconstruction is still possible following salvage mastectomy in previously irradiated patients.

How to assess appearance distress and motivation in plastic surgery candidates: Italian validation of Derriford Appearance Scale 59 (DAS 59)

OBJECTIVE

The Derriford Appearance Scale (DAS) 59 was specifically designed to measure psychosocial adjustment in patients with appearance problems. Previous studies using the DAS59 have proven it to be a reliable method of assessing the appearance-related quality of life after plastic surgery procedures. The aim of this study was to develop a valid and reliable Italian version of the DAS59.

PATIENTS AND METHODS

The first Italian translation of this questionnaire was conducted according to the DAS59 protocol that was designed by the original authors of the questionnaire. Eight hundred patients participated in this study and filled out three questionnaires (DAS59, General Health Questionnaire (GHQ)12 and Beck's Depression Inventory (BDI)-II). There were 400 adult patients with a history of previous plastic surgeries and 400 adult patients without any personal history of previous plastic surgery procedures. A total of 50 patients were selected randomly for test-retest analysis.

RESULTS

The overall internal consistency was excellent (α = 0.95) and equal to that of the original article that first described the scale. There was a good correlation between all the items. Domains demonstrated good internal consistency (Cronbach's alpha) and correlation within themselves. The construct validity of the Italian DAS59 was assessed under convergent validity that confirmed the correlation with scales related to other psychological conditions. GHQ12 showed relevant correlation with DAS59, while BDI-II did not.

CONCLUSIONS

A valid and reliable Italian DAS59 version was developed that can be used for research and clinical assessment of patients with appearance problems and concerns, especially before and after plastic surgery procedures.

Foot deformities in Renaissance paintings. A mystery of symbolism, artistic licence, illusion and true representation in five renowned Renaissance painters

Although Renaissance artists were skilled in representing normal anatomy, a close look at some paintings reveals anatomical variations in the depiction of the feet of human figures. A systematic review has identified 25 paintings by five artists in which the presumptive medico-artistic diagnosis of congenital or acquired foot deformity seems to be varyingly present. The connection between these five painters and what factors have influenced artists' style in the depiction of such deformities is discussed. The possible iconography and medical-historical meaning of such variations, as well as the possibility of artistic licence and real representation that drove the painters to depict these deformities, is explored and debated.

Iloprost administration in acrodermatitis of Hallopeau complicated by acquired toes syndactyly: a case report and review of the literature

OBJECTIVE

Acrodermatitis Continua of Hallopeau (ACH) is a variant of pustular psoriasis often very difficult to treat. Secondary syndactyly, also called "pseudosyndactyly", is rare and can be a complication of burns, dystrophic epidermolysis bullosa or trauma. If left untreated, joint complications and definitive functional impairments may occur.

CASE REPORT

We report a case of a 74-year-old man with acrodermatitis continua of Hallopeau involving the toes and complicated by syndactyly. ACH regression following Iloprost administration was also observed.

DISCUSSION

Published studies are mainly limited to case reports only, due to the rarity of the disease. Therefore, there are no clear-cut therapeutic management guidelines available for this chronic and sometimes debilitating disease. ACH is often recalcitrant to the available therapies. Topical and systemic treatments have been described in literature with no long-lasting results.

CONCLUSIONS

To our knowledge, this is the first report of foot syndactyly associated to ACH. In our patient, ACH symptoms regressed with Iloprost administration: this finding has never been previously described in literature. If confirmed by other clinical experiences, Iloprost could be a further therapeutic option in ACH.

Computational modeling and stress analysis of columellar biomechanics

The open approach for rhinoplasty offers excellent exposure of the various components of the nose in situ. The biggest advantage of the external approach is the complete anatomic exposure, which allows the surgeon to inspect the osteo-cartilagineous framework, while the biggest disadvantage is represented by the transcolumellar scar. The goal of this study is to numerically quantify the stress induced on the scar of a human columella by a constant load, through a fine tuned finite elasticity continuum model. Specifically we want to determine the best shape of incision which would minimize this stress. The columellar portion of the nose, together with the various constituting tissues, has been modeled in a first approximation as a hyperelastic body and seven types of scars have been studied. The determination of the best incision must be a compromise among different factors: shape and size primarily, but also position with respect to the internal structures and external loads. From this point of view, the best class of scar appears to be, both at simulated and real levels, the V-shaped one, inducing a maximum logarithmic von Mises stress in tissue of 4.67 Pa, and an absolute minimum stress distribution on the scar of 4.17 Pa. Numerical simulations appear to be in agreement with the evidence-based results coming from surgical practice, thus confirming the necessity to minimize local stresses on the tissue. A parameters' sensitivity analysis further highlighted our optimal choice. The proposed mathematical model can be applied both to theoretically designed and numerically verified new non-conventional scar geometries.

Breast hypertrophy and asymmetry: a retrospective study on a sample of 344 consecutive patients

BACKGROUND

Preoperative evaluation of the anatomical features of the region around the breast is strongly recommended in order to choose the most appropriate technique of reductive mammaplasty. Normally breast hypertrophy presents itself as a bilateral clinical picture, but no study in the literature refers to the incidence of volumetric asymmetry.

AIMS

This study aims to analyze weight differences between the right and left breast on a selected sample of patients who underwent reductive mammaplasty or mastopexy over the last five years at our Plastic Surgery Unit and have maintained a good postoperative symmetry for at least 1 year subsequently.

PATIENTS AND METHOD

344 consecutive cases treated between January 2005 and April 2010 were considered for this study. Patients were classified according to the degree of hypertrophy and age. Breast asymmetry was scored, according to the senior author's original classification, on the weight difference of glandular resection.

RESULTS AND CONCLUSION

In 20% of the patients a difference greater than 200 g was found. The statistical analysis showed no significant differences in the predominant side (left or right). Breast hypertrophy is confirmed as a substantially bilateral pathology, but in 1 out of 5 patients a difference of more than one quadrant can be present: thus a careful evaluation is essential in order to decide the correct surgical strategy.

Heterologous reconstruction and radiotherapy: the role of latissimus dorsi flap as a salvage

AIM

The versatility and effectiveness of the latissimus dorsi flap as salvage in complicated heterologous reconstructions, especially with regards to radiotherapy, is examined in this retrospective review of our 10-year experience.

METHOD

Twenty-eight patients with complicated heterologous reconstruction were divided into three groups: (1) 15 patients with mastectomy and immediately expander reconstruction and radiation; (2) 9 patients with previous QUART, salvage mastectomy and immediate expander reconstruction; (3) 4 patients with radical mastectomy without radiation.

RESULTS

The most common complications were capsular contracture and radiodermitis in Group 1, cutaneous fistula in Group 2. Recipient site complications, after latissimus dorsi flap, were observed in seven patients (five smokers), five in Group 1, two in Group 2. Cosmetic result was scored excellent and good in 25 patients (89%).

CONCLUSION

This study shows as a favourable and cosmetically satisfactory reconstruction can be achieved when combining an implant with a latissimus dorsi flap allowing the salvage of the entire heterologous reconstruction.

Giant scrotal elephantiasis: an idiopathic case

Scrotal elephantiasis is very rare disease in industrialized countries, where it is mainly due to surgery, irradiation or malignancies. It can be defined as idiopathic only when the possible congenital, infectious and compressive causes are excluded. We report a case of massive scrotal lymphoedema in an adult Caucasian patient, in Italy. He presented an extremely voluminous scrotal mass measuring 50 x 47 x 13 cm (weight 18 kg), which extended below his knees, invalidating all his daily activities. The patient was hospitalized in order to undergo to surgical treatment. Although genetic causes were searched and the possible role of infectious agents and compressive factors was evaluated, no etiology was ascertained. Histopathologic examination showed non-specific chronic inflammation, confirming the diagnosis of idiopathic elephantiasis. One year after surgical treatment, the patient is healthy without recurrence signs.

Le lambeau pédiculé en îlot vasculaire proximal de fibula dans la reconstruction distale du fémur. Étude anatomique

The fibular pedicled proximal vascular island flap for distal femoral bone reconstruction described for the first time by Cariou on 1996, is studied in this article with an anatomical view. This anatomical morphometric study allows to assure the surgeon that this procedure can be done and to precise the surgical technique. The authors showed that, dependent on the length of the lower limb and the level of the fibular artery origin, 10 to 19 cm of femoral bone reconstruction could be done, after 180 degrees flap rotation. The flap can be used, the fibula separated in two parts, for inferior femoral metaphysis reconstruction or for knee joint arthrodesis.

Expression and heterodimer-binding activity of Ku70 and Ku80 in human non-melanoma skin cancer

BACKGROUND

Experimental data suggest that exposure to ultraviolet radiation may indirectly induce DNA double-strand breaks.

AIM

To investigate the contribution of the non-homologous end-joining repair pathway in basal and squamous cell carcinomas.

METHODS

Levels of Ku70 and Ku80 proteins were determined by immunohistochemical analysis and Ku70-Ku80 heterodimer-binding activity by electrophoretic mobility shift assay. Matched pathological normal margins and skin from healthy people were used as controls.

RESULTS

A significant increase in Ku70 and Ku80 protein levels was found for both tumour types as compared with normal skin (p<0.001). Squamous cell carcinoma showed increased immunostaining as compared with basal cell tumours (p<0.02). A direct correlation was found between Ku70 and Ku80 protein levels and expression of the proliferation markers Ki-67/MIB-1 (p<0.02 and p<0.002, respectively) in basal cell carcinoma. DNA binding activity was increased in basal cell carcinoma samples as compared with matched skin histopathologically negative for cancer (p<0.006). In squamous cell carcinomas, however, the difference was significant only with normal skin (p<0.02) and not with matched pathologically normal margins.

CONCLUSIONS

Overall, an up regulation of the Ku70 and Ku80 protein levels seems to correlate only with tumour proliferation rate. As non-homologous end joining is an error-prone mechanism, its up regulation may ultimately increase genomic instability, contributing to tumour progression.

Cell cycle related proteins as prognostic parameters in radically resected non-small cell lung cancer

BACKGROUND

Experimental evidence suggests that lung cancer development and progression can be linked to an increased proliferation rate.

AIMS/METHODS

To evaluate the immunohistochemical expression of seven components of the cell cycle machinery in a series of well characterised non-small cell lung cancer (NSCLC) specimens (n = 105).

RESULTS

Multivariate analysis revealed that simultaneous loss of expression of three of these factors--cyclin D1, the cyclin dependent kinase inhibitor p16, and the tumour suppressor retinoblastoma protein Rb2/p130--correlated with survival, confirming the hypothesis that the cyclin D1-p16-retinoblastoma tumour suppressor pathway is inactivated in most lung cancer samples.

CONCLUSIONS

These results suggest that loss of control of cell cycle checkpoints is a common occurrence in lung cancer and support the idea that functional cooperation between different cell cycle regulatory proteins constitutes another level of regulation in cell growth control and tumour suppression.

Cutaneous lymphoadenoma: a rare clinicopathological entity

Cutaneous Lymphadenoma (Benign Lymphoepithelial tumour of the skin) is a rare tumour, with distinctive clinical and histological features. To date, very few cases of this entity have been reported. We present a case of cutaneous lymphoadenoma in a 52-year-old man and a short review of the literature, summarizing the principal clinical and morphological characteristics of this rare tumour.

[Role of cutaneous thoraco-abdominal flap in the surgical treatment of advanced stage breast tumors]

Chest wall reconstruction following extensive resection due to advanced breast cancer or radionecrosis still represents a challenge for both oncologic and reconstructive surgeons. A multitude of techniques including pedicle muscle transposition, free muscle flaps and omental flaps have always been considered, despite the morbidity of donor site. The authors describe a new cutaneous thoraco-abdominal flap to cover full thickness defects up to 600 cm2. 16 patients underwent chest wall reconstruction with the aforementioned technique. No major complications occurred. This technique proved to be a very good options to cover large chest wall defects in patients with advanced or recurred breast cancer or radionecrosis.

[Strategic approach to immediate breast reconstruction with submuscular-fascial tissue expanders]

Breast reconstruction can be accomplished with implants, autologous tissue or both. Thanks to the widespread of microsurgical techniques autologous tissue reconstruction has become a frequent option in many departments although it is mostly considered a second choice. The aim of this study was to review our experience covering the past five years in immediate breast reconstruction with tissue expanders. From January 2000 to January 2005 279 patients underwent immediate breast reconstruction with submuscular tissue expanders. Tissue expander was chosen according to dimension, shape and volume of the healthy breast. Operating time, early and late complications, interference with neo-adjuvant therapies as well as timing and surgical techniques of second-step reconstruction were also considered. No major complications occurred. Tissue expander, beyond proving itself a valid and safe option in immediate breast reconstruction, also decreased the psychological distress following a mastectomy.

[Myanmar mission]

They underline the interest of this type of mission and provide us their reflexion about team training, the type of relation with the country where the mission is conducted and the type of right team.

Analysis of cell cycle regulator proteins in non-small cell lung cancer

BACKGROUND/AIMS

Abnormalities of the proteins involved in cell cycle checkpoints are extremely common among almost all neoplasms. This study aimed to investigate the expression of four components of the cell cycle machinery-p21, p16, p53, and proliferating cell nuclear antigen (PCNA)-in non-small cell lung cancer (NSCLC).

METHODS

The expression of p21, p16, p53, and PCNA was examined in 68 well characterised NSCLC specimens using immunohistochemistry. The coregulation of these proteins and their influence on survival were analysed using both univariate and multivariate analyses.

RESULTS

By univariate analysis, the expression of all the proteins examined, except for PCNA, was significantly correlated with survival. In multivariate analysis, the only immunohistochemical parameter able to influence overall survival was p16, confirming the hypothesis that the RB-p16 tumour suppressor pathway is inactivated in most lung cancer samples. Finally, the group of patients with NSCLC who were negative for both p21 and p16 had a significantly shorter overall survival.

CONCLUSIONS

These results suggest that loss of control of cell cycle checkpoints is a common occurrence in lung cancers, and support the idea that functional cooperation between different cell cycle inhibitor proteins constitutes another level of regulation in cell growth control and tumour suppression.

Pleomorphic adenoma of cervical heterotopic salivary glands

Neoplastic transformation of heterotopic cervical salivary gland tissue is extremely rare. The Authors describe a case of pleomorphic adenoma arising in this tissue, on the right side of the neck in a 40-year old man. The characteristics of salivary heterotipias of the neck, and their diagnostic difficulties and histogenetic problems are reviewed.

Gynecomastia and the complete circumareolar approach in the surgical management of skin redundancy

Gynecomastia is a benign enlargement of the male breast due to a physiological or pathological factor that interferes with the balance between estrogens and androgens in the serum. Gynecomastia itself requires no treatment unless the persistent enlargement of the male breast is a source of embarrassment and/or distress for the adolescent or adult man. The indications for the surgical treatment of gynecomastia are founded on two main objectives: (1) the restoration of male chest shape and (2) diagnostic evaluation of suspected breast lesions. The diagnostic evaluation begins with an adequate history and a thorough breast examination helped by laboratory tests and instrumental research. Several approaches for surgical treatment have been described in the literature. Some problems arise in patients who have significant enlargement and ptosis of the breast that will require skin reduction and in some patients requiring nipple-areola complex reduction. The authors believe that the complete circumareolar technique with purse-string suture creates the best aesthetic results, with fewer complications, in patients with moderate and severe ptotic glandular breast enlargements that have skin redundancy combined with areolar enlargement. From 1995 through 1999, a total of 10 male patients with moderate to severe gynecomastia were treated surgically using a complete circumareolar approach. All patients achieved a good aesthetic contour of the chest. Only two patients required a revision of the circumareolar scar to correct postoperative enlargement.

[Treatment of gynecomastia using a trans-areolar incision]

Thirty cases of gynecomastia treated surgically in Rio de Janeiro are presented. Possible aetiological factor are discussed and the technique employed, trans-areolar incision and preparation of two retro-areolar flaps, described. The technique may be associated or not with liposuction.

Electric burns of the lip

Young children, usually aged between 1 and 3 years, are frequent victims of electric burns of the lip caused by contact with an electric plug or extension cord. In this article, the authors classify the various types of lesions in 19 cases of electric burns of the lip and discuss surgical treatment approaches.
