Immediate, bilateral transverse rectus abdominis musculocutaneous (TRAM) flap reconstruction after mastectomy

Although breast reconstruction has been shown to provide psychological benefits in mastectomy patients, there is reluctance to perform immediate, bilateral TRAM flap reconstruction because of concerns regarding magnitude of the procedure, length of hospitalization, potential complications, and long-term recovery. Between June, 1990 and March 1992, 15 patients underwent immediate, bilateral TRAM flap reconstruction following bilateral mastectomy at the University of Michigan Hospitals. Diagnoses included lobular carcinoma in situ (nine patients), strong family history of breast cancer (five), or bilateral breast cancer (one). Invasive breast cancer was present in three patients. Three modified radical mastectomies and 27 simple mastectomies were performed. Bilateral pedicle TRAM flap reconstruction was carried out at the same time in all patients (30 flaps total). Marginal loss occurred in one flap (3%). Additional complications included marginal necrosis of the abdominal donor site wound (one), wound infection (two), and abdominal donor site hernia (one). Median hospital stay was 7 days. Median follow-up was 13 months (range 4-25 months). All patients have resumed their accustomed pre-operative activity patterns. These findings demonstrate that immediate, bilateral TRAM flap reconstruction is a safe and effective option for breast reconstruction after mastectomy.     

Ti(C,N)基金属陶瓷抗弯强度的Weibull分析

作为金属切削工具材料,Ti(C,N)基金属陶瓷强韧性的可靠性是制约其推广应用的主要因素。由于Ti(C,N)基金属陶瓷比WC基硬质合金脆性更大,其强韧性对内外缺陷更敏感,抗弯强度分散性更大,使用时,极易出现突然断裂,失效可预测性低。本文采用Weibull统计强度理论以及双样本t检验的方法对工业化批量生产的Ti(C,N)基金属陶瓷的抗弯强度(TRS)的可靠性及其主要影响因素进行分析。结果显示,物料批次、烧结炉次(烧结气氛)对抗弯强度的分散性有显著影响。同物料批次、同炉次烧结的Ti(C,N)基金属陶瓷样本的抗弯强度具有较大的Weibull模数,最高可达m=41.64,而多物料批次、多炉次烧结样本的抗弯强度的分散性较大,Weibull模数约为10~15,特征强度约为(2350±150)MPa。抗弯强度的Weibull分布还受到样品尺寸的影响,小尺寸样品的特征强度更大,但Weibull模数更小。     

The vaginal transverse low segment hysterotomy for second trimester therapeutic abortion (author's transl)

A series of 100 therapeutic abortions by vaginal hysterotomy is reported. This method of vaginal hysterotomy with a transverse low segment incision just above the internal os of the cervix was first described by Fuchs in 1939. The important advantage of this method is complete avoidance of the uterine cervix. With this method a therapeutic abortion after the tenth week of gestation and in a few cases, up to the 20th week of gestation can be accomplished by a fast one stage technique with few side effects. The method is considered to be superior to the injection methods and the two stage procedures. With skill in vaginal operative techniques, this method can be used in any gynaecological department as a routine method. In this series, 28 cases had concomitant tubal ligations. There were two subsequent pregnancies. Complications were one uterine perforation during the curettage requiring laparotomy and suture. There was one laceration of the trigon of the bladder requiring suture. There were 2 cases of hemorrhage. There were 6 inflammatory reactions in the perimetria of which two required administration of antibiotics. There was superficial thrombophlebitis in one case. And there was a severe coagulation defect in one case of a missed abortion at 5 months gestation.

Influence of transverse rolling on the

The influence of transverse rolling passes on the recrystallization texture was investigated in an effort to strengthen the {111} 〈uvw〉 type components and reduce the intensity of the {100} 〈0vw〉 components, improve the uniformity of the microstructure, and refine the grain size in high-purity tantalum plate. Tantalum, from three different ingot breakdown processes, received an additional 80 pct reduction in the transverse direction (perpendicular to the ingot centerline) in the processing schedule prior to final annealing. This work investigated the influence of the additional transverse rolling passes on the development of texture in the as-rolled tantalum and also in rolled plus annealed tantalum. After annealing, the tantalum plates had significantly strengthened {111} 〈uvw〉 crystallographic orientations, not only for the side forged process, but also for the upset and side forged tantalum. For tantalum processed by extrusion, the transverse rolling did not improve the final recrystallized texture.     

Spontaneous hematoma of the transverse mesocolon

We describe a patient with aspergillosis of the maxillary antrum, and systemic affectation (anemia, anorexia, fever). Through a Caldwell-Luck approach, the maxillary antrum was opened and an irregular mass removed, postoperatively the patient has done well, disappearing in two months the ORL and systemic symptoms.     

Test of the acute cardiac ischemia time-insensitive predictive instrument (ACI-TIPI) for prehospital use

A broad range of nickel-containing alloys and coatings used in jewellery, watches and clothes, were patch tested in 100 nickel-sensitive subjects and in 20 nickel-negative controls. Three non-plated stainless-steel alloys tested caused no patch-test reaction. Nickel interliners under gold, silver or chromium plating, as well as nickel-silver and some white-gold alloys, caused positive patch-test reactions. Ear ornaments, wristwatches and buttons were the objects most frequently causing dermatitis. Half the nickel-sensitive participants suspected that they had been sensitized before the age of 20. The results of the study have been used as the basis for developing clinically relevant analytical methods for nickel release. The methods are proposed as European Standards and will be used in the Nickel Directive, an EC regulation aiming at the prevention of nickel allergy.     

A comparison of two screening tests (the Matrix Analogies Test—Short Form and the Kaufman Brief Intelligence Test) with the WISC-III.

This study examined the concurrent validity of two brief intelligence tests, the Matrix Analogies Test—Short Form (MAT; J. A. Naglieri, 1985) and the Kaufman Brief Intelligence Test (K-BIT; A. S. Kaufman & N. L. Kaufman, 1990), with the Wechsler Intelligence Scale for Children—Third Edition (WISC-III; D. Wechsler, 1991) using a sample of 50 referred students who were attending a large urban school district. The MAT/WISC-III and K-BIT/WISC-III correlations were high and did not differ significantly in magnitude (rs?=?.67 and .78, respectively). Both screening tests tended to give scores that were significantly higher than the WISC-III Full Scale IQ. Administration time was under 10 min for both screening tests. The MAT and K-BIT appeared to be equally useful as screening tests when the WISC-III was the criterion measure. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Exploring the validity of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) with established emotions measures.

Emotions measures represent an important means of obtaining construct validity evidence for emotional intelligence (EI) tests because they have the same theoretical underpinnings. Additionally, the extent to which both emotions and EI measures relate to intelligence is poorly understood. The current study was designed to address these issues. Participants (N = 138) completed the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), two emotions measures, as well as four intelligence tests. Results provide mixed support for the model hypothesized to underlie the MSCEIT, with emotions research and EI measures failing to load on the same factor. The emotions measures loaded on the same factor as intelligence measures. The validity of certain EI components (in particular, Emotion Perception), as currently assessed, appears equivocal.

A case of bilateral optic neuropathy and recurrent transverse myelopathy associated with perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA)

The purpose of this study was to evaluate skeletal and dental effects of bionator headgear combination appliances on patients in development period with Class II, division 1 malocclusion. The comparison of computerized X-ray cephalometric measurements between the 26 treated children and 26 untreated children was made. The results showed that ANB angle was significantly reduced and horizontal mandibular growth development tended to be normal in the treated group. It was suggested that the bionator headgear combination appliance can restrain the maxillary growth early and promote the forward mandibular growth which contribute the functional jaws correction.
