The authors report their experience on the nonsurgical treatment of capsular contractures due to breast implant augmentation
mammaplasty. External ultrasonic repeated applications have been applied to 24 patients after closed capsulotomy procedures
in order to reduce the recurrency rate. The new ultrasonic device used was based on a 2-MHz generator with a timing adjustable
power emission connected to eight transducers designed for breast anatomy. The authors report significant improvement of the
closed capsulotomy technique demonstrating a persistent stability of the achieved results in 82% of the treated contractures,
even in severe cases (Baker's IV), after a minimum follow-up period of 12 months. Methods of application, technical features
of the ultrasonic device, experimental charts, and results obtained on 34 breast implant capsular contractures are reported
and discussed. 相似文献

A case report of late spontaneous extrusion of a 250-cm3, round, texturized silicone gel mammary implant, 14 months after implantation, is presented. The irregular surface of the
implant, the location of the implant pocket, and the absence of the fibrous capsule were responsible for alterations in the
skin thickness. In addition, the pressure exerted by the implant against the skin provides for stasis with venous trombosis
at the inferior portion of the breast. The continuous manipulation of the breast over a thin skin with vascular alterations
led to the skin perforation with implant extrusion. 相似文献

Breast Augmentation: Teaching Our Patients How Compression Can Help Prevent Capsular Contracture 总被引:2,自引:0,他引:2
If we insert a foreign body into a human being, physiologically, we get a capsular contracture because a periprosthetic scar
contracts to give the implant a spherical shape, the smallest surface area for a given volume. To antagonize this contracture,
one must stretch the periprosthetic scar and this can be accomplished with compression. 相似文献

The authors report their experience in five years of treating breast implant capsular contractures with an external ultrasonic
device that facilitates the closed capsulotomy technique. A set of 52 patients have been treated with a 82.6% of improvement
at a year follow up. Methods of application and results are discussed. 相似文献

Sprengel deformity is a rare orthopedic condition that is associated with functional and cosmetic impairment. Results of
orthopedic procedures are usually inconsistent and cosmetic results are far from satisfactory in these patients. A silicone-gel-filled
calf prosthesis was used to correct the shoulder contour in a patient with Sprengel deformity. Cosmetically the deformity
can be restored by using a calf implant for patients in whom orthopedic procedures are not likely to yield a satisfactory
outcome. 相似文献

Attention has been drawn to elevated laboratory tests of inflammation as indicators of a possible reaction to silicone breast
implants. These patients have complaints of joint pain, pain, and myalgia that were possibly caused by a reaction to silicone.
This study is a retrospective review of 100 consecutive patients (79 female, 21 male) who were evaluated because of a purported
industrial injury to the upper extremity. Patients were examined by a single examiner and all had laboratory screening for
indicators of inflammation (sedimentation rate, anti-nuclear antibody levels, C-reactive protein, anti-streptolysin, rheumatic
factor), endocrine abnormalities (thyroid panel), and serum glucose. None of the patients had any history of breast augmentation
with any implant. Of the 79 female patients, 50 had an identifiable clinical diagnosis and 18 of them had elevation of at
least one of the indicators of inflammation. The remaining 29 did not have an identifiable diagnosis and 21 of them had elevation
of at least one indicator of inflammation (P < 0.01). There were 74 out of 79 females with subjective complaints of upper extremity pain, joint pain, and aching. Forty-five
of these patients had an identifiable diagnosis and 17 of them had elevation of at least one inflammatory indicator. Of the
74 female patients, 29 had no identifiable diagnosis and 21 of them had elevation of at least one inflammatory indicator (P < 0.01). In summary, there were a high number of female patients with complaints of upper extremity symptoms with no prior
exposure to silicone from breast implantation. There was a statistically significant correlation in these patients who had
no identifiable diagnosis and elevated indicators in inflammation. This study suggests these markers of inflammation should
not be used as indicators of a reaction to silicone from breast implantation in patients with upper extremity subjective complaints. 相似文献

The etiology of capsular contracture is unclear and probably multifactorial. This review covers the literature on several
proposed contracture factors, including filler material, implant placement, surface texture, and bacterial infection. The
pilot study's goal was to test the feasibility of a data collection form, which could be used in a scaled-up study analyzing
multiple surgeon's records. The goal of the expanded version of this study will be to determine the efficacy of available
interventions for capsular contracture, including surveillance. The Breast Implant Public Health Project, LLC (BIPHP), piloted
a retrospective review of outcomes in women who had interventions to relieve capsular contracture or had chosen a wait-and-watch
approach. An evaluation of the efficacy of various treatments can help women decide if they want to pursue treatment at all
and, if so, which treatment might offer them the best solution. BIPHP researchers (E.E.A., M.E.) developed a data collection
form after reviewing records of three surgeons (B.C., W.P., V.L.Y.). During the data collection using the same records, we
tested a randomization process to identify women with capsular contracture who underwent various interventions, including
a wait-and-watch strategy, and those who had no mention of any intervention or waiting approach. Data were gathered on a total
of 90 breasts with capsular contracture (scored Baker I–IV or qualitatively), of which 45 underwent a total of 102 interventions
for capsular contracture. Interventions were classified as ``closed capsulotomy,' ``surgical,' or ``watchful waiting.'
Closed capsulotomy was performed most often (47%), followed by surgery (29%) and watchful waiting (21%). Presurgical Baker
scores averaged higher in breasts that underwent surgery (3.1) than for watchful waiting (2.5) or closed capsulotomy (2.3).
Though closed capsulotomies had 100% of outcomes scoring ``improved' or ``same,' 58% of the breasts underwent the procedure
more than once, suggesting that the favorable outcome was short-lived. The wait-and-watch approach resulted in scores of either
``same' or ``worse'; surgery (open capsulotomy, repsoitioning, or capsulectomy) resulted in 79% improved, 16% same, and
5% worse outcomes in breasts with outcomes listed. In all intervention procedure categories, outcomes were frequently unavailable;
they were noted only 60% of the time (52/87). The missing 40% may have resulted from the doctor's failure to note it in the
chart, satisfied patients not returning for additional treatment, or dissatisfied patients seeking treatment elsewhere. Generally,
the data collection forms and procedures were workable; however, we uncovered issues to address in the scale-up of this pilot
study: (1) the outcome report rate was 60%; (2) though Baker scores are commonly used to evaluate the degree of capsulaar
contracture, it seems that grade I may have different meanings for different surgeons, which would need to be clarified; (3)
participating surgeons will need to divulge standard-of-care items that they may not have included in medical records, but
routinely performed (e.g., patient massage, use of prophylactic antibiotics); and (4) records were initially separated by
``implant,' then researchers realized that a more useful collection would be by ``breast.' The latter approach captures
the history of the breast in one record, which may be more important to contracture than the differences in implants. With
the modifications discussed, the study can be scaled up to encompass as many records as necessary to achieve robust statistical
power. These data will add to the existing literature regarding factors associated with capsular contracture and identify
factors that affect the successful outcome of capsular contracture interventions. 相似文献

A prospective study of a new mammary prothesis with PVP-based gel as filling material was carried out. Scheduled follow-ups
were planned at 3, 6, 12, and 24 months post-implantation to assess all complications, Baker scores, and the patient's, and
the physician's global assessment of each implant. PVP-filled implants were used in 95 breasts for augmentation (60%) or reconstruction
(40%). Sixty-nine percent of all patients underwent a primary procedure, 19% had a history of severe capsular fibrosis. During
follow-up, a hematoma was observed in 2% and a seroma in 5%. Leakage occurred in 3% (one iatrogenic and two cases of unknown
reason), a Baker 3 in 6% (12 months). No volume increase of the implants occurred. The probability that a patient would be
complication-free at 24 months was 0.86. Physician's and patient's satisfaction rating after 12 months remained high without
any time effect (physician very good/good 63%, patient 75%). According to our current experiences, the PVP-filled implants
are a remarkable alternative with an improved viscosity and enhanced x-ray transmission, compared to saline filled implants. 相似文献

The authors present their experience with the surgical treatment of capsular contracture to achieve better results in a safe,
predictable, and practical way, and discuss the possible treatment modalities. They simply advise leaving the capsule intact,
even if it is calcified, and create another pocket, rarely in the front or, more typically, at the back of the capsule. If
the breast tissue is also ptotic, a mastopexy procedure may be added to the procedure, in addition to augmentation, with a
rather small prosthesis placed in the new pocket or, occasionally, in the old one. External, forceable massage is not advisable
to treat the capsule. Open capsulotomy and/or partial capsulectomy can be applied to release the capsule. However, it is not
advisable since recurrence is usually inevitable. The purpose of this paper is to present a series of surgical procedures
to avoid the problems created by the capsule and present different cases with good results. 相似文献

We present our experience with augmentation mammaplasty on 14 patients with a thin chest wall and poor subcutaneous tissue.
Thanks to Polytech Silimed code 20675, a new anatomical prosthesis filled with ``soft' cohesive gel, the lodging in a subglandular
position was possible without anomalous salience in the upper pole, and a more natural mammary profile was achieved without
capsular contracture, dislocation, or misplacement of the mammary implants. 相似文献

This pilot study's goal was to test the feasibility of a data collection form which will be used in a scale-up study analyzing
multiple surgeons' records. The goal of this expanded study will be to develop identifying factors for women who are at greater
risk for having ruptured implants and, if necessary, target them for screening, surveillance, or intervention. In the pilot
study, we compared factors associated with implant rupture in women with and without rupture. Similar studies have considered
one or a few factors at a time and, generally, have given little attention to implant generation. We developed a data collection
form after reviewing records of three surgeons. A total of 92 records was collected and analyzed. An important feature in
the pilot was to compare the results of patients whose implants the surgeons had both implanted and explanted (n= 34) with those of patients whose implants the surgeons had only explanted (n= 55) (unknown = 3). This comparison could show if including all explantation patients in a surgeon's practice would bias
the sample; however, based on this pilot data, concerns regarding this type of bias seem to be minimal. Similar amounts of
data (e.g., implant information, history of capsular contracture, etc.) were collectible on patients whose surgeons both implanted
and explanted them (87%) and who had different surgeons for implantation and explantation (84%). Though the data from this
limited sample cannot offer firm conclusions on rupture associations, a few factors stood out: size of implants (38.3% of
ruptured versus 15.9% of intact implants were 100–200 cm3), history of mammography (46.8% of ruptured versus 24.4% of intact had mammograms, which is likely due to older women with
older implants having more mammograms), and history of closed capsulotomy (85.1% of ruptured versus 68.9% of intact). Interestingly,
additional procedures performed on the breast (e.g., scar revision, wound repair, etc.) did not affect rupture: both the ruptured
and the intact groups had an average of 1.7 procedures performed. The data collection form tested very well in this pilot
study. Also, including all patients in the study sample, instead of excluding those who received their implants elsewhere,
did not change the results. Though there are not enough data to draw any firm conclusions regarding rupture factors, the collection
instrument was rigorously tested and should perform well in an expanded study. 相似文献

Inspired by successful reconstruction obtained using the Lewis–Ryan lower thoracic advancement flap to rebuild missing breast,
we have adapted that extremely simple technique to prior serial expansions, in order to create more natural mounds, better
defined submammary folds, and when possible, some grade of ptosis, without additional, new scarring. The procedure is introduced
and compared to other such flaps as the TRAM and the latissimus dorsii. In our series, 30 patients were evaluated according
to the quality of the final results, and the most frequent complications are pointed out and discussed. 相似文献

Augmentation mammaplasty is one of the most common aesthetic procedures performed. Early complications of the procedure are
hematoma and infection, and late complications include capsular contracture and device failure or its displacement. Failure
of saline implants is readily identifiable, whereas rupture of silicon gel implants can occur without symptoms due to lack
of volume loss. Autoinflation of the breast caused by intracapsular and intraprosthetic collection of sterile pus has been
reported. A series of five consecutive breast autoinflations with sterile pus is presented. All the patients presented with
acute swelling of the breast 2–10 years after prostheses implantation. Intracapsular sterile pus with macroscopic shell tear
was seen in four cases. In the remaining case, an intracapsular and intraprosthetic collection of sterile pus with a tear
in an otherwise intact implant was seen under the microscope. All five cases showed no microbial growth on culture or sensitivity,
and all were treated using a single-stage procedure. The follow-up periods ranged from 8 weeks to 1 year without recurrence
of symptoms. 相似文献

Laparoscopic surgery has emerged as the standard of care for the elective operative management of symptomatic gallbladder
disease. The surgical literature is now beginning to accumulate sufficient case numbers that more clearly define the associated
morbidity of this type of surgery. This article reports an instance of iatrogenic injury to the right muscular hemidiaphragm
and subsequent hernia after laparoscopic cholecystectomy.

We describe a new, highly sensitive semiquantitative method for rapid measurement of in vitro mineralization using calcein. Fluorescence analysis of the calcein bound to the calcium phosphate (hydroxyapatite) allows
direct quantitation of extracellular matrix mineral content in monolayer cultures of bone-forming cells such as primary osteoblasts
or osteosarcoma cells. Osteosarcoma cell lines UMR 106 and SaOS-2 were used to demonstrate that qualitatively, calcein was
bound to the same regions of the mineralized cell monolayer as seen by conventional histological staining with von Kossa or
Alizarin Red S. Moreover, total bound calcein could be quantitated by direct fluorescence analysis using a Cytofluor II plate
reader. Changes in cell monolayer calcein fluorescence were shown to correlate well with direct colorimetric measurement of
acid-solubilized Ca+2 from parallel cultures. Relative mineral quantitation by calcein fluorescence is rapid and more sensitive than colorimetric
Ca+2 assays, can be performed directly on unfixed or fixed cell monolayers, and does not require the use of radioisotopes. The
cell monolayer remains intact and potentially available for further analysis.

Laminin, the major basement membrane glycoprotein of the blood vessel, inducing many cellular responses, inhibited the differentiation
of osteoclasts in a rat bone marrow culture system when immobilized on the surface of the culture wells, showing that laminin
acts as a negative regulator of osteoclast differentiation in a nonsolubilized form. Laminin inhibited the process of preosteoclast
formation from early progenitor cells in bone marrow. This laminin-mediated inhibition of osteoclastogenesis was blocked by
the addition of laminin fragment YIGSR, indicating that the inhibitory effect of laminin was mediated via laminin receptors.
This finding suggests a significant role of basement membrane laminin of the blood vessels as a negative regulator of osteoclastogenesis.

Evaluation of laparoscopic Toupet fundoplication as a primary repair for all patients with medically resistant gastroesophageal reflux 总被引:5,自引:2,他引:3
Background: This prospective study assesses the outcome results in 100 consecutive patients with gastroesophageal reflux disease (GERD)
treated with a laparoscopic Toupet fundoplication.
Methods: GERD was confirmed by 24-h pH study and/or esophagogastroduodenoscopy (EGD). Pre- and postoperative symptoms, operative times,
and perioperative complications were recorded on standardized data forms. Early follow-up was at 3 months and late follow-up,
including 24-h pH, manometry, and EGD was at 22 months.
Results: Preoperative symptoms included heartburn (92%), regurgitation (58%), water brash (39%), and dysphagia (39%). Mean operative
time was 3.2 hours. There were no conversions to celiotomy and there were no mortalities. The perioperative complication rate
was 14%; 6% (5/83) of patients reported heartburn at 3 months and 20% (15/74) at 22 months. Early and late dysphagia was 20%
(17/83) and 9% (7/74), respectively; 24-h pH testing was abnormal in 90% of symptomatic patients (9/10), 39% of asymptomatic
patients (12/31), and 51% overall.
Conclusions: Despite early improvement in reflux symptoms following laparoscopic Toupet fundoplications, there is a high incidence of
recurrent GERD. Symptomatic follow-up underestimates the true incidence of 24-h pH-documented reflux. Based on these results
we cannot recommend the laparoscopic Toupet repair for GERD patients with normal esophageal motility.

The objectives of this study were to learn how hip fracture patients fall, and to compare the mechanics of their falls with
those falls that did not result in hip fracture. In this way we sought to obtain reliable insight into the etiology and pathogenesis
of hip fracture and fracture prevention. A total of 206 consecutive patients with fresh hip fracture and 100 controls were
interviewed and examined between October 1994 and May 1996. The only inclusion criterion was that the fracture had occurred
within 24 hours of hospital admittance. The control subjects were admitted from the same community after an accidental fall
that did not result in hip fracture. The characteristics of the accident were determined by personal interview and examination
of the patients within 24 hours of the event. In 98% of the hip fracture patients, the fracture was a result of a fall. The
majority of the patients (76%) reported that they had fallen directly to the side. Forty-eight fracture cases had one or more
eyewitnesses and their reports supported this observation. In 56% of the hip fracture patients, a fresh subcutaneous hematoma
was seen on the greater trochanter of the proximal femur; such a hematoma was rare in the controls (6%) (P < 0.001), and this gave evidence for the direct impact of the greater trochanter during the fall of the hip fracture subjects.
Most of the elderly fallers who fractured a hip did not manage to break the fall, e.g., with an outstretched arm. In conclusion,
our results suggest that a typical hip fracture is the result of a fall and a subsequent impact on the greater trochanter
of the proximal femur. The clinical implication of this finding is that effective prevention of hip fractures could be achieved
by the diminution of the number and severity of falls of the elderly. We suggest that the severity of the falls (impacts on
the greater trochanter) could be decreased by an external hip protector.

In order to determine the effects of age on bone quality, human bone tissue taken from adult subjects deceased from violent
death was analyzed by means of fast Fourier transform infrared spectrophotometry (FTIR) in the Diffuse Reflectance mode (DR).
This technique allows the characterization of both the mineral and organic parts of bone in a nondestructive manner. Only
the organic part is discussed in this report. A quantitative change in the entire organic part of bone tissue is observed
with the aging of subjects. The effects of these changes on bone strength were not measured.

The growing antler of 1-year-old red deer is an excellent system in which to study processes involved in ``cartilage model'
endochondral-type bone growth. Antlers grow from the tip, permitting the developmental sequences of bone formation to be studied
as distance-dependent phenomena, in which early processes can be observed at the distal end, and later events are sequentially
more proximal. Quantitative light microscope histochemical assays for alkaline phosphatase (ALP) and phosphodiesterase I (PDE
I) were used to determine the activities of these two phosphohydrolases in relation to antler mineralization and remodeling.
Both enzymes were absent in proliferating young cartilage near the end, but progressively increased in activity in a proximal
direction. ALP levels were maximal when mineralization was just beginning, whereas PDE I activity was greatest more proximally,
where mineralization was more complete. This study provides strong indirect evidence that each of these enzymes has a function
in mineralization, but that their roles are not identical.
