Results of this multicentric study have shown that by giving Master Amino acid Pattern (MAP) as a sole and total substitute of dietary proteins to 500 overweight participants undergoing the American Nutrition Clinics/Overweight Management Program (ANC/OMP), the participants' body nitrogen balance could be maintained in equilibrium with essentially no calories (MAP 1 g=0.04 kcal), thereby preserving the body's structural and functional proteins, eliminating excessive water retention from the interstitial compartment, and preventing the sudden weight increase after study conclusion commonly known as the yo-yo effect. Study results have shown that the use of MAP, in conjunction with the ANC/OMP regimen, has proven to be safe and effective by preventing those adverse effects associated with a negative nitrogen balance, such as oversized or flabby tissue, stretch marks, the sagging of breast tissue, increased hair loss, faded hair color, and fragile or brittle nails. Also prevented were those anomalies commonly associated with weight-loss diets, such as hunger, weakness, headache caused by ketosis, constipation, and decreased libido. The use of MAP in conjunction with the ANC/OMP also allowed for mean weight loss of 2.5 kg (5.5 lb) per week, achieved through reduction of excessive fat tissue and elimination of excessive water retention from the interstitial compartment.

Master Amino acid Pattern as substitute for dietary proteins during a weight-loss diet to achieve the body's nitrogen balance equilibrium with essentially no calories.

Results of this multicentric study have shown that by giving 10 g (10 tablets) of Master Amino acid Pattern (MAP) as a substitute for dietary proteins, once a day, to 114 overweight participants undergoing the American Nutrition Clinics/Overweight Management Program (ANC/OMP), the participants' nitrogen balance could be maintained in equilibrium with essentially no calories (MAP 1 g=0.04 kcal), thereby preserving the body's structural and functional proteins, eliminating excessive water retention from the interstitial compartment, and preventing the sudden weight increase after study conclusion commonly known as the yo-yo effect. Study results have shown that the use of MAP, in conjunction with the ANC/OMP, has proven to be safe and effective by preventing those adverse effects associated with a negative nitrogen balance, such as oversized or flabby tissue, stretch marks, sagging of breast tissue, increased hair loss, faded hair color, and fragile or brittle nails. Also preventing those anomalies commonly associated with weight-loss diets, such as hunger, weakness, headache caused by ketosis, constipation, or decreased libido, the use of MAP, in conjunction with the ANC/OMP, allowed for mean weight loss of 1.4 kg (3 lb) per week.

Extreme pulsus alternans with P wave alternans in a child.

Pulsus alternans was observed in a child with left ventricular dysfunction secondary to systemic hypertension. The Echo-Doppler of supravalvular aorta and a simultaneous electrocardiographic trace (ECG) clearly demonstrated the mechanism of an apparent abrupt halving of pulse frequency compared with the ECG, similar to an electromechanical dissociation 2:1. Besides the extreme pulsus alternans, a P wave and a PP cycle length change were also observed. Both mechanical and electrical alternans disappeared with afterload reduction by nitroprusside treatment.

[Analysis and long-term survival in sternectomy with plastic reconstruction for primary and secondary neoplasms of the sternum].

From January 1980 to December 1999, 88 patients underwent surgical resection for tumours involving the sternum. Thirty were males, aged 16 to 76 years, and 58 females, aged 23 to 78 years (mean ages: 48 and 53 years, respectively). There were 30 primary malignant tumours, 28 local recurrences or distant metastases from breast cancer, 16 other tumours, and 14 radionecroses. Total sternectomy was performed in 8 cases, subtotal (> 50%) in 32, and partial (< 50%) in 48. Concurrent en-bloc resection of the anterior ribs was performed in 61 patients, and of the clavicle in 13. Resection was extended to the lung in 22 patients, to the pericardium in 17, to both in 2, to the diaphragm and pericardium in 4. Bone and soft tissue defects were repaired with prosthetic material associated with a muscular or myocutaneous flap in 55 patients, with prosthetic material alone in 13 cases, with a muscular or myocutaneous flap in 5 cases, and with other techniques in the remaining patients. The resection was considered to be macroscopically radical in 78 patients and palliative in 10 cases. There was one perioperative mortality and significant morbidity was limited to 13 cases. Among the patients treated with a radical intent, 48 were alive and disease-free at the end of follow-up. The 10-year survival rate was 85% in primary tumours. For breast cancer relapses, 10-year survival was the same as 5-year survival (41.8%). In our experience, an en-bloc sternal resection for a primary or secondary tumour, followed by plastic repair using prosthetic material and/or a myocutaneous flap, is a safe, effective treatment. This intervention permits the execution of extensive radical resections for sternal neoplasms, as well as enabling the patient to obtain a better quality of life. Long-term survival after radical sternectomy also depends on the histological type of the tumour.

Fibro-cartilaginous lesions of the glenoid labrum in shoulder instability: a proposed classification using sagittal-oblique arthro-MRI.

PURPOSE: To propose a graded classification of lesions of the fibrocartilaginous glenoid labrum in traumatic dislocations of the shoulder, based on arthro-MRI in sagittal-oblique views. MATERIALS AND METHODS: Seventy-one patients with histories of chronic post-traumatic shoulder instability were studied from May 2000 to May 2001. MR images were obtained using superconducting magnets operating at 1 and 1.5 Tesla, with a dedicated shoulder coil. The study was carried out in combination with arthrography, with axial sections oriented perpendicularly to the longitudinal axis of the glena, oblique coronal sections parallel to the course of the supraspinous muscle tendon and oblique sagittal sections with axis parallel to the longitudinal axis of the glena. RESULTS: In one case an anatomical variant was found (Buford complex). In 18 patients a simple fissuration of the fibrocartilaginous glenoid labrum was found, whereas 28 patients displayed more extensive lesions affecting the middle-inferior portions of the labrum. In 15 patients the lesion extended to the middle-superior third of the glena, involving the middle glenohumeral ligament. In 9 cases, in addition to a complete lesion of the labrum, with typical "bucket-handle" appearance, a lesion of the superior and middle glenohumeral ligaments was also observed. DISCUSSION AND CONCLUSIONS: In traumatic shoulder dislocations it is essential to provide the surgeon with precise information regarding the location, extension and degree of damage to the capsule, ligaments and especially the labrum of the glenohumeral joint. On the basis of the results obtained in the sagittal-oblique sections we propose an MR-arthrography classification dividing lesions of the fibrocartilaginous labrum into 4 grades.

Anterior-inferior shoulder instability: treatment based on the Thal method.

Purpose of this study is to analyze the results of a consecutive series of 139 patients affected with anterior-inferior shoulder instability and treated by arthroscopic capsuloplasty using the Thal method with absorbable and non-absorbable Mitek knotless anchors. Much attention was paid to the preoperative and intraoperative selection of patients, excluding from the arthroscopic procedure those with bony Bankart lesions measuring more than 25%, with an inverted-pear glenoid, with engaged Hill-Sachs lesions and patients with HAGL lesions. Pre- and postoperative clinical evaluation was carried out using the Rowe scale. Scores rose from 45-55 to 96 postoperatively. Intra-articular mobilization of the anchors did not occur and peri-metallic lysis was not manifested. Areas of bone resorption were observed in 7 cases (7/38, 18.4%) with the presence of peri-insertional geodes with biological anchors, but this had no effect on the clinical results.
