Modified anterior intercostal artery perforator flap (AICAP) for autologous breast volume restoration after explantation.

Explantation of breast implants has become increasingly common. This study aimed to analyze breast auto-augmentation following implant explantation (using a laterally designed anterior intercostal artery perforator [AICAP] flap) in patients who did not need new implants and required volume preservation. Twenty-four patients (48 breasts) aged 31-67 years (mean, 52.4 years) with body mass index (BMI) between 24.43 and 29.34 (mean, 27.32) kg/m2 underwent this procedure. All patients had implant-related problems, such as recurrent capsular contracture (n=11), seroma (n=2), animation deformity (n=3), rupture-induced bleeding (n=5), and breast implant disease (n=3). Sizes of implants removed ranged from 215 to 355 ml. The mean flap size was 23.9 cm × 7.5 cm, and the average flap thickness was 2.3 cm (range, 2.0-3.2 cm). Flap survival was clinically examined postoperatively by ultrasonography. Pre- and postoperative final breast volumes were compared by direct patient observation and independent photograph observation by three plastic surgeons according to a 4-point scale (bad=1, regular=2, good=3, and excellent=4) and the brassiere size. All flaps were completely viable after harvesting. No postoperative signs of fat necrosis were observed, and independent plastic surgeon evaluation revealed good and excellent results in all cases. Patient satisfaction evaluated by BREAST-Q data was >90%. This new design, AICAP flap (with a lateral thoracic extension), can be safely used for breast volume restitution after breast implant explantation with high patient satisfaction. This flap exhibited reasonable potential of providing additional volume in patients who undergo implant explantation and require the preservation of similar volume.

International multidisciplinary expert panel consensus on breast reconstruction and radiotherapy.

BACKGROUND: Conflicting evidence challenges clinical decision-making when breast reconstruction is considered in the context of radiotherapy. Current literature was evaluated and key statements on topical issues were generated and discussed by an expert panel at the International Oncoplastic Breast Surgery Meeting in Milan 2017. METHODS: Studies on radiotherapy and breast reconstruction (1985 to September 2017) were screened using MEDLINE, Embase and CENTRAL. The literature review yielded 30 controversial key questions. A set of key statements was derived and the highest levels of clinical evidence (LoE) for each of these were summarized. Nineteen panellists convened for dedicated discussions at the International Oncoplastic Breast Surgery Meeting to express agreement, disagreement or abstention for the generated key statements. RESULTS: The literature review identified 1522 peer-reviewed publications. A list of 22 key statements was produced, with the highest LoE recorded for each statement. These ranged from II to IV, with most statements (11 of 22, 50 per cent) supported by LoE III. There was full consensus for nine (41 per cent) of the 22 key statements, and more than 75 per cent agreement was reached for half (11 of 22). CONCLUSION: Poor evidence exists on which to base patient-informed consent. Low-quality studies are conflicting with wide-ranging treatment options, precluding expert consensus regarding optimal type and timing of breast reconstruction in the context of radiotherapy. There is a need for high-quality evidence from prospective registries and randomized trials in this field.

ANTECEDENTES: El hecho de que la evidencia disponible sea conflictiva supone un reto para la toma de decisiones a la hora de considerar la reconstrucción mamaria en el contexto de radioterapia (radiotherapy, RT). En el seno de un panel de expertos reunidos durante el International Oncoplastic Breast Surgery Meeting celebrado en Milán en 2017, se revisó la literatura disponible y se generaron y discutieron los aspectos más relevantes. MÉTODOS: Se hizo una búsqueda bibliográfica de los estudios de RT y reconstrucción mamaria (1985-septiembre de 2017) en las bases MEDLINE, EMBASE y CENTRAL. La revisión de la literatura permitió identificar 30 cuestiones clave controvertidas. A partir de ellas, se construyeron una serie de afirmaciones, para las que se obtuvo el mayor nivel de evidencia (levels of clinical evidence, LoE) posible. El acuerdo, desacuerdo o abstención respecto a las cuestiones propuestas fueron el resultado de las discusiones de 19 expertos reunidos durante el International Oncoplastic Breast Surgery Meeting. RESULTADOS: Se identificaron 1.522 artículos publicados en revistas con peer review. Se elaboró una lista de 22 afirmaciones clave y se anotó el LoE más alto obtenido para cada una de ellas. El grado de variabilidad fue de II a IV, pero la mayoría de las afirmaciones (54,5%) obtuvieron un LoE III. Hubo un consenso total en el 41% (9/22) de las afirmaciones, mientras que se obtuvo más de un 75% de acuerdo en la mitad de las afirmaciones (11/22). CONCLUSIÓN: La evidencia en la que basar el consentimiento informado en estos pacientes es escasa. Se trata de estudios de baja calidad con gran variedad de opciones terapéuticas, que dificultan el consenso de los expertos acerca del tipo y momento óptimo para la reconstrucción mamaria en el contexto de RT. Para obtener datos de mayor calidad se precisan estudios prospectivos y ensayos clínicos en este campo.

Lethal cardiac amyloidosis: Modification of the Congo Red technique on a forensic case.

Congo Red staining is usually used in diagnosing amyloidosis, a pathology characterized by the storage of abnormal proteins in several human organs. When assessed on samples fixated in formalin and embended in paraffin, this staining can undergo several artefacts, causing diagnostic and interpretative difficulties due to its weak stainability and a consequent reduced visibility of the amyloid. These complications, in time, requested several variations of this staining technique, especially in clinical practice, while in the forensic field no protocols has ever been adapted to cadaveric samples, a material that is already characteristically burdened by a peculiar stainability. In our work, studying a sudden death caused by cardiac amyloidosis and diagnosed only with post-mortem exams, we present a modified Congo Red staining used with the purpose to demonstrate amyloid in cadaveric material after the unsuccessfully use of all standard protocols.

Retirada de implantes mamarios y corrección simultánea con colgajo dermoglandular inferior. Técnica de mastopexia con autoprótesis / Breast implant explantation and simultaneous correction with inferior dermoglandular flap authoprosthesis technique

Los cirujanos plásticos nos enfrentamos cada vez con más frecuencia en nuestra consulta a pacientes que desean o necesitan retirar sus implantes mamarios. Algunas de estas pacientes rechazan la idea de un reemplazo protésico, pero son exigentes con el resultado cosmético postoperatorio. Describimos la técnica empleada en 68 casos consecutivos y los resultados que hemos obtenido al tratar las secuelas en la mama tras la retirada de los implantes, fundamentalmente una disminución de volumen asociada a ptosis y excedente cutáneo. Esta técnica se basa en la extracción de los implantes y correccion mamaria simultanea con colgajo dermoglandular inferior que denominamos "autoprotesis" asociado a injerto graso simultáneo. Los resultados logran mejorar la forma, proyección y conificacion de la mama tras la retirada de los implantes, con un alto grado de satisfacción por parte de las pacientes (AU)

Plastic surgeons are frequently faced during consultation with patients who want or need breast implant explantation. Some of these patients reject the idea of a prosthetic replacement, but are demanding with the postoperative cosmetic result. We describe the technique used in 68 consecutive cases and our results to deal with breast alterations after breast implant explantation, leaving a decreased mammary volume, ptosis and a loosy cutaneous excedent. With this technique of explantation and simultaneous breast correction with de-epithelialized dermoglandular flap, "authoprosthesis", associated with simultaneous fat grafting, we can get a good result regarding the shape, projection and coning of the explanted breast, with high patient satisfaction (AU)

Corrección de la mama tuberosa solo conimplantes anatómicos / Tuberous breast correction only with anatomical implants

Las mamas tuberosas, denominadas así por Rees y Aston, y también llamadas hernias del complejo areolar (Bass), Snoopy deformity (Gruber), mamas tubulares (Williams), hipoplasia del polo inferior (Brink) o mamas de base estrecha (Puckett), son una malformacion en el desarrollo del volumen mamario en los cuadrantes inferiores con hernia areolar secundaria (placa areolar y músculo mamilar débiles), areola ancha y protruida (en la mitad de los casos), ascenso del surco submamario, mamas hipotróficas y raramente hipertróficas, con asimetrías en las dos terceras partes de las pacientes. Presentamos la estrategia quirúrgica adecuada para resolver esta patología utilizando solo implantes anatómicos de gel cohesivo sin necesidad de tallar colgajos glandulares. De esta manera, disminuimos la morbilidad quirúrgica, ofreciendo resultados estables y con alta satisfaccion por parte de las pacientes (AU)

Tuberous breasts, denominated like this by Rees and Aston, and also called areolar complex hernia by Bass, Snoopy deformity by Gruber, tubular breasts by Williams, inferior pole hypoplasia by Brink, tight base breasts by Puckett, are a malformation of breast with inferior quadrants alteration that produce an areolar herniation and protrusion (in fifty per cent of the cases), and elevation of the infamammary fold; they are rarely hypertrophic and with asymmetries in two thirds of the patients. Authors present the surgical strategy to solve this pathology just using high cohesive silicone gel anatomical implants without needing of glandular flap tailoring. By this way, surgical morbidity is diminished offering stable results and high patient satisfaction (AU)

Sudden death from systemic sarcoidosis: a case of legal medicine.

INTRODUCTION: The sarcoid condition of vital organs such as heart, lungs, liver and brain, may constitute, though rarely, a dangerous situation for survival. In forensic pathology, sudden death related to such disease represents an unusual event occurring in subjects who die unexpectedly in spite of their previous good health, and whose autopsy reveals, mainly, the involvement of heart or the central nervous system (CNS). THE CASE: The Authors describe a case of sudden death due to systemic sarcoidosis with atypical presentation in a young South American nulliparous woman showing, as the only symptom, occasional episodes of spotting during the last two months of her life. RESULTS: The only noteworthy finding from the autopsy resulted in secondary obstructive hydrocephalus. The subsequent forensic toxicological examination was negative, whereas the histopathological examination, conducted by means of post-fixation techniques and standard coloring methods on the viscera removed during autopsy, revealed useful data to determine the cause of death, consisting of a diffuse inflammatory reaction with giant cells and epithelioid cells of sarcoid type localized in the CNS and in the genitourinary apparatus. CONCLUSIONS: The case presented, ranking among deaths occurred unexpectedly, is a useful opportunity both for clinical remarks, given its inherent diagnostic difficulties, especially in the presence of atypical symptoms, and for legal medicine ones, given the inclusion of sarcoidosis in cases of sudden death that can give rise to criminal investigations.

Effect of in vivo administration of naloxone on ATP-ase's enzyme systems of synaptic plasma membranes from rat cerebral cortex.

Naloxone is a specific competitive antagonist of morphine, acting on opiate receptors, located on neuronal membranes. The effects of in vivo administration of naloxone on energy-consuming non-mitochondrial ATP-ases were studied in two different types of synaptic plasma membranes from rat cerebral cortex, known to contain a high density of opiate receptors. The enzyme activities of Na+, K(+)-ATP-ase, Ca(2+), Mg(2+)-ATP-ase and Mg(2+)-ATP-ase and of acetylcholinesterase (AChE) were evaluated on synaptic plasma membranes obtained from control and treated animals with effective dose of naloxone (12microg x kg(-1) i.m. 30 minutes). In control (vehicle-treated) animals specific enzyme activities assayed on these two types of synaptic plasma membranes are different, being higher on synaptic plasma membranes of II type than of I type, because the first fraction is more enriched in synaptic plasma membranes. The acute treatment with naloxone produced a significant decrease in Ca(2+),Mg(2+)-ATP-ase activity and an increase in AChE activity, only in synaptic plasma membranes of II type. The decrease of Ca(2+), Mg(2+)-ATP-ase enzymatic activity and the increased AChE activity are related to the interference of the drug on Ca(2+) homeostasis in synaptosoplasm, that leads to the activation of calcium-dependent processes, i.e. the extrusion of neurotransmitter. These findings give further evidence that pharmacodynamic characteristics of naloxone are also related to increase [Ca(2+)]i, interfering with enzyme systems (Ca(2+), Mg(2+)-ATP-ase) and that this drug increases acetylcholine catabolism in synaptic plasma membranes of cerebral cortex.

Chinese flap in head and neck surgery.

Twenty patients underwent resections for head and neck cancer. The reconstructive procedure used was the free forearm flap with microsurgical technique on 22 occasions. The free forearm flap was used in its simple or composite form, with double or manifold islands, with a segment of the radius for mandible reconstruction or with two islands joined solely by the vascular pedicle, constituting what the authors call "tandem flap", with excellent results. The procedure does not replace conventional ones, but the authors believe it should be regarded as one of the choice flaps by surgeons dedicated to this special field.
