RESUMEN

BACKGROUND: The 2 genes KCNQ1 (LQT1) and HERG (LQT2), encoding cardiac potassium channels, are the most common cause of the dominant long-QT syndrome (LQTS). In addition to QT-interval prolongation, notched T waves have been proposed as a phenotypic marker of LQTS patients. METHODS AND RESULTS: The T-wave morphology of carriers of mutations in KCNQ1 (n=133) or HERG (n=57) and of 100 control subjects was analyzed from Holter ECG recordings. Averaged T-wave templates were obtained at different cycle lengths, and potential notched T waves were classified as grade 1 (G1) in case of a bulge at or below the horizontal, whatever the amplitude, and as grade 2 (G2) in case of a protuberance above the horizontal. The highest grade obtained from a template defined the notch category of the subject. T-wave morphology was normal in the majority of LQT1 and control subjects compared with LQT2 (92%, 96%, and 19%, respectively, P:<0.001). G1 notches were relatively more frequent in LQT2 (18% versus 8% [LQT1] and 4% [control], P:<0.01), and G2 notches were seen exclusively in LQT2 (63%). Predictors for G2 were young age, missense mutations, and core domain mutations in HERG. CONCLUSIONS: This study provides novel evidence that Holter recording analysis is superior to the 12-lead ECG in detecting G1 and G2 T-wave notches. These repolarization abnormalities are more indicative of LQT2 versus LQT1, with G2 notches being most specific and often reflecting HERG core domain missense mutations.

RESUMEN

An improved technique for reduction mammaplasty is described that has the advantage of giving a satisfactory final shape to the breast while producing a minimal scar. The method involves periareolar deepithelialization with displacement of the nipple-areola complex, partial subcutaneous mastectomy at the base of the mammary cone, and a Z-plasty to interlock two triangles of skin left after the removal of a little excess skin in the region above the inframammary fold. The Z-plasty adds skin vertically to the inferior pole, resulting in a better final shape and reducing tension around the areola. Any further excess skin is left to retract spontaneously. The best indications for this operation are in young women with elastic skin free of striae "gravidarum." Our experience now covers 53 patients aged 14 to 30 years with reductions of up to 900 gm per breast, and we have encountered no major complications over a 3-year follow-up period.

RESUMEN

Subcutaneous mastectomy is becoming an operation of choice in certain cases of premalignant and other breast pathology. We describe a technique for simultaneous subcutaneous mastectomy and retropectoral implantation of a silicone prosthesis. Gentle blunt prepectoral, retromammary dissection is performed through an axillary incision as far inferiorly as the inframammary fold, where a fibrous bridge between the anterior surface of the pectoralis major muscle and the skin prevents dissection any lower. Through the same incision, the retropectoral space is dissected to about 5 cm below the inframammary fold. A second incision is made in the inframammary fold to join the retromammary plane of the first dissection. The gland is then dissected subcutaneously and removed through the inframammary incision. A silicone implant is introduced retropectorally through the axillary incision, thus avoiding splitting the pectoralis major. Satisfactory results have been obtained in 23 bilateral and 14 unilateral cases; it is important that the dissection be performed carefully in order to prevent the implant from riding up too high in its musculoaponeurotic sling.

RESUMEN

It is surprising that in a recently published symposium on reconstruction of the nose, not one article mentioned the tempororetroauricular flap described by Washio. In our experience, this method is a very useful tool for difficult nasal reconstructions in young individuals. It is a safe procedure (not to be compared with free flaps of the same region), and it provides thin skin and cartilage that can be adapted for different types of defect. Exceptionally, it may provide a sufficient amount of tissue for a total nose reconstruction. As compared with most other techniques, it leaves no additional scar on the face.

RESUMEN

A case report of a young patient with marked asymmetry treated successfully with ultrasonically assisted lipectomy with a good functional cosmetic result, undetectable scars, and mammographic control and showing no ill-effect on the breast parenchyma is presented. Further studies and follow-up are needed to confirm the value and advisability of using ultrasonic energy in the female breast.

RESUMEN

A depressed supratarsal sulcus can be filled by means of a soft-tissue arterial flap including subcutaneous tissue, galea, and periosteum. The donor site is the temporal region, and the flap is passed subcutaneously into the upper eyelid. The same type of flap can also be used as filling material in other situations, such as Treacher-Collins malar bone defects. The correction of a depressed supratarsal sulcus by anophthalmic orbits is to be done only after complete and careful adjustment of the eye prosthesis by the ocularist, or after adjustment of the socket itself.

RESUMEN

The subperiosteal face lift described by Psillakis has been criticized for not showing a more dramatic improvement over conventional brow/face lift procedures. His approach also has a significantly high incidence of nerve injury. This study reports our anatomic findings and surgical modifications, which have permitted a significant improvement in the safety of execution and clinical results using the subperiosteal face lift concept. Pertinent points of applied local anatomy and dissection techniques are as follows: First, we use extensive interconnected subperiosteal dissection that includes the entire zygomatic arch. This allows better repositioning of the deep soft tissues of the entire upper face, most of the midface, and indirectly, key structures of the lower face. Second, the upward pull of the muscles of the cheek and mouth will produce an elevation of the corner of the mouth, affecting positively the smiling mechanism, the oral frowning, and the jowls. Third, the dissection deep to both layers of the temporal fascia decreases the risk of injury to the frontalis nerve. Fourth, the temporal fascia is used as a lifter and anchoring element of the entire cheek-perioral soft tissues as opposed to the periorbital fibrofatty tissues. This will decrease the risk of injuring the frontal and zygomatic branches of the facial nerve. These modifications have been used in 28 patients. Our rate of patient satisfaction has been high, and no complications with regard to nerve injury have been observed. This compares favorably with our initial 60 patients, in whom the Psillakis or Tessier approach was used. In these patients, there was an 11 and 20 percent rate of nerve injury, respectively.

RESUMEN

Cardiac complications are common in adolescent anorexia nervosa and are the cause of a third of deaths. Some workers have reported prolongation of the QT interval and cases of sudden death in these patients. The aim of this study was two-fold: to assess the cardiac complications of anorexic adolescents and to determine the outcome after renutrition in the hospital setting. This was a prospective study of 48 consecutive cases (45 girls) with an average age of 14 +/- 2 years, admitted to the paedopsychiatric unit and fulfilling the DSM-IV criteria of anorexia nervosa. The digitised ECG, Holter ECG and echocardiography were recorded before and after renutrition. Anorexia nervosa was severe with a body mass index < 14 in 2/3 of cases. Over 2/3 of patients had bradycardia with a heart rate < 50/min in half the cases but normal chronotropic function on Holter monitoring. Prolongation of the QTc interval was demonstrated (QTc > 440 ms in 11/44 cases). Echocardiographic abnormalities, in particular left ventricular dysfunction (24/46) and pericardial effusion (12/46) were reversible after renutrition. There were no clinical or biological predictive factors for the occurrence of cardiac complications on admission. The authors confirm that cardiac complications of anorexia nervosa are common, usually benign and always reversible after renutrition in hospital. Therefore, most electrical abnormalities normalise with the heart rate and echocardiographic abnormalities with improvement of conditions of load.

RESUMEN

Breast reconstruction was carried out with rectus abdominis musculocutaneous flap on 7 women (8 breasts) with defect of breast, and perfect result was obtained on all the patients. The flap which was normally excised in an abdominal lipectomy was used to cover the defect of breast. The rectus abdominis of the flap was used to fill the reconstractive breast and to carry the vascularization from the internal mammary artery. The advantages of the method are as follow: (1) the waist-line is reduced by closing the musculoaponeurtic defect; (2) The scar of the donor area is well hidden by the abdominoplasty; (3) The breast reconstruction need not use an implant. The disadvantage is a risk of postoperative herniation if the suture tears.
