RESUMO

BACKGROUND: Hand eczema is a common and persistent disease with a relapsing course. Clinical data suggest that once daily treatment with corticosteroids is just as effective as twice daily treatment. OBJECTIVES: The aim of this study was to compare once and twice daily applications of a strong corticosteroid cream in addition to maintenance therapy with a moisturizer in patients with a recent relapse of hand eczema. METHODS: The study was a parallel, double-blind, randomized, clinical trial on 44 patients. Twice daily application of a strong corticosteroid cream (betamethasone valerate 0.1%) was compared with once daily application, where a urea-containing moisturizer was substituted for the corticosteroid cream in the morning. The investigator scored the presence of eczema and the patients judged the health-related quality of life (HRQoL) using the Dermatology Life Quality Index (DLQI), which measures how much the patient's skin problem has affected his/her life over the past week. The patients also judged the severity of their eczema daily on a visual analogue scale. RESULTS: Both groups improved in terms of eczema and DLQI. However, the clinical scoring demonstrated that once daily application of corticosteroid was superior to twice daily application in diminishing eczema, especially in the group of patients with lower eczema scores at inclusion. CONCLUSIONS: Twice daily use of corticosteroids was not superior to once daily use in treating eczema. On the contrary, the clinical assessment showed a larger benefit from once daily treatment compared with twice daily, especially in the group of patients with a moderate eczema at inclusion.

RESUMO

BACKGROUND: Disease modifying drugs help control the course of relapsing remitting multiple sclerosis (RRMS); however, good adherence is needed for long-term outcomes. OBJECTIVE: To evaluate patient adherence to treatment with subcutaneous interferon beta-1a using RebiSmart® and assess injection-site reactions and treatment satisfaction. METHODS: This prospective, single-arm, open-label, noninterventional multicenter Phase IV trial included disease modifying drug-experienced mobile patients with RRMS. Adherence was measured over 12 weeks. Items 13-23, 35, 37, and 38 of the Multiple Sclerosis Treatment Concerns Questionnaire (injection-site reactions and treatment satisfaction) were recorded at 12 weeks. RESULTS: Sixty patients were recruited (mean age 43.7 [±SD 7.9] years; 83% female; mean years since multiple sclerosis diagnosis 6.7 [SD 4.5]). Adherence data were obtained in 54 patients only due to technical problems with six devices. Over 12 weeks, 89% (n=48) of patients had ≥90% adherence to treatment. Most patients experienced mild influenza-like symptoms and injection-site reactions, and global side effects were minimal. Most patients (78%) rated the convenience as the most important aspect of the device, and most experienced no or mild pain. CONCLUSION: RRMS patients treated with subcutaneous interferon beta-1a, administered with RebiSmart, demonstrated generally good adherence, and the treatment was generally well tolerated.

RESUMO

OBJECTIVES: We sought to assess the feasibility and accuracy of myocardial contrast echocardiography (MCE) using standard imaging approaches for the detection of perfusion defects in patients who had a myocardial infarction (MI). BACKGROUND: Myocardial contrast echocardiography may be more versatile than perfusion scintigraphy for identifying the presence and extent of perfusion defects after MI. However, its reliability in routine practice is unclear. METHODS: Fundamental or harmonic MCE was performed with continuous or triggered imaging in 203 patients with a previous MI using bolus doses of a perfluorocarbon-filled contrast agent (NC100100). All patients underwent single-photon emission computed tomography (SPECT) after the injection of technetium-99m (Tc-99m) sestamibi at rest. Quantitative and semiquantitative SPECT, wall motion and digitized echocardiographic data were interpreted independently. The accuracy of MCE was assessed for detection of segments and patients with moderate and severe sestamibi-SPECT defects, as well as for detection of patients with extensive perfusion defects (>12% of left ventricle). RESULTS: In segments with diagnostic MCE, the segmental sensitivity ranged from 14% to 65%, and the specificity varied from 78% to 95%, depending on the dose of contrast agent. Using both segment- and patient-based analysis, the greatest accuracy and proportion of interpretable images were obtained using harmonic imaging in the triggered mode. For the detection of extensive defects, the sensitivity varied from 13% to 48%, with specificity from 63% to 100%. Harmonic imaging remained the most accurate approach. Time since MI and SPECT defect location and intensity were all determinants of the MCE response. The extent of defects on MCE was less than the extent of either abnormal wall motion or SPECT abnormalities. The combination of wall motion and MCE assessment gave the best balance of sensitivity (46% to 55%) and specificity (82% to 83%). CONCLUSIONS: Although MCE is specific, it has limited sensitivity for detection of moderate or severe perfusion defects, and it underestimates the extent of SPECT defects. The best results are obtained by integration with wall motion. More sophisticated methods of acquisition and interpretation are needed to enhance the feasibility of this technique in routine practice.

RESUMO

Currently, breast cancer is one of the most common malignant lesions among women in North America--it occurs in one in every nine such women. Approximately 180,000 cases will be diagnosed this year. During the past 3 years at the Mayo Clinic, approximately 4,000 breast biopsies were performed. In approximately 20% of such biopsy specimens, a malignant lesion will be identified. Surgeons should be aware of the current possibilities in breast reconstruction and should consider the cosmetic result in the placement of breast biopsy incisions. Even lesions in the superior or inferior portions of the breast are accessible through generous periareolar incisions. The biopsy incision should be within the confines of a possible skin excision for mastectomy to avoid creating two scars if the specimen proves cancerous. The choice of site for the biopsy incision, however, should never jeopardize the treatment of the cancer. Appropriate preoperative planning will ensure optimal cosmetic and therapeutic results in the management of breast lesions.

RESUMO

OBJECTIVE: To assess the results of transverse rectus abdominis musculocutaneous (TRAM) flap reconstructions of the breast. DESIGN: We retrospectively reviewed 147 consecutive cases of TRAM reconstructions of the breast performed at the Mayo Clinic between 1981 and 1992. MATERIAL AND METHODS: The median patient age was 47 years, and the median duration of follow-up was 29 months. In 25 patients, both rectus pedicles were used, 15 of those for bilateral reconstruction. The other 122 patients had unipedicled unilateral reconstruction. Only 9% of the breast reconstructions were immediate. Analysis of risk factors in the patient population revealed smoking in 16%, preoperative irradiation of the chest wall in 20%, preoperative chemotherapy in 27%, and both radiotherapy and chemotherapy in 12%. RESULTS: The mean overall operative time was 4 hours and 43 minutes (4 hours and 20 minutes for unipedicled flaps and 5 hours and 46 minutes for bipedicled reconstructions). No blood transfusion was needed in 47% of patients; of those who received transfusions, 78% required 2 units or less. In 58 of the 147 patients (39%), an operation was performed on the contralateral breast. Follow-up operations were necessary in 71% of patients. The overall frequency of complications was as follows: hernia that necessitated surgical repair, 7.5%; full TRAM ischemic loss, 3.7%; partial TRAM loss, 9.9%; and fat necrosis, 11.7%. No pattern of increased complications was noted in subgroups of patients who smoked or who had received preoperative irradiation, chemotherapy, or both. In comparison with our early cases, the last 50 TRAM procedures were generally associated with fewer complications. The rates of occurrence of complications in our series of patients were similar to those reported in the literature. CONCLUSION: The TRAM flap provides satisfactory results for reconstruction of the breast.

RESUMO

OBJECTIVE: The objectives of this study were to determine whether the combination of complex tumor-ablative surgery and microvascular free tissue transfer reconstruction delays the onset of postoperative radiation therapy, whether free tissue transfers are lost after a course of radiation therapy, and what patterns of tumor recurrence and survival rates are present in patients who undergo this type of multidisciplinary treatment. DESIGN: A retrospective review was conducted in 37 patients who underwent tumor-ablative surgery and reconstruction between November 1987 and August 1991. MATERIAL AND METHODS: Of the 30 men and 7 women who underwent tumor-ablative surgery, microvascular free tissue transfer reconstruction, and postoperative radiation therapy, recurrent or T4 primary tumors were treated in 84%. Sixty-two percent of the patients had nodal metastatic disease. The median dose of postoperative irradiation was 60 Gy (range, 32.4 to 76.8). Follow-up in all patients was until death (21 patients) or for a median of 17.5 months (range, 4.1 to 43.2). RESULTS: The median duration of overall survival and the 2-year overall survival rate were 17 months and 46%, respectively. For cause-specific survival, the median duration and 2-year rate were 17 months and 50%, respectively. Local recurrence developed in 8 patients, neck recurrence in 10, and distant metastatic disease in 11. No microvascular free tissue transfers failed. CONCLUSION: Radiation therapy can begin in most patients within 8 weeks postoperatively, microvascular free tissue transfers seem to tolerate postoperative radiation therapy well at the doses administered, and the rates of local and neck control are reasonable relative to the advanced stage of the cancers treated.

RESUMO

Forty-five patients (36 male and nine female) were treated for postpneumonectomy empyema. All were initially managed with the first stage of the Clagett procedure (open pleural drainage). In 28 patients with associated bronchopleural fistula the fistula was closed and reinforced with muscle transposition at the time of open drainage. Seven patients had multiple flaps. The serratus anterior muscle was transposed in 28 patients, latissimus dorsi in 11, pectoralis major in four, pectoralis minor in one, and rectus abdominis in one patient. After the fistula was closed and the pleural cavity was clean, the second stage of the Clagett procedure (obliteration of the pleural cavity with antibiotic solution and closure of the open pleural window) was done. The number of operative procedures ranged from 1 to 19 (median 5.0). Length of hospitalization ranged from 4 to 137 days (median 34.0 days). There were six operative deaths (mortality rate 13.3%), none in the patients who had both stages of the Clagett procedure. Follow-up of the 39 operative survivors ranged from 2.1 to 90.2 months (median 21.8 months). Eighty-four percent of patients in whom the Clagett procedure was completed (26/31) had a healed chest wall with no evidence of recurrent infection. The bronchopleural fistula remained closed in 85.7% of patients (24/28). There were 19 late deaths, none related to postpneumonectomy empyema. We conclude that the Clagett procedure remains safe and effective in the management of postpneumonectomy empyema in the absence of bronchopleural fistula and that intrathoracic muscle transposition to reinforce the bronchial stump is an effective procedure in the control of postpneumonectomy-associated bronchopleural fistula.

RESUMO

Our experience with Klippel-Trenaunay syndrome (KTS), a rare congenital malformation, has increased considerably in recent years and now includes 144 patients (65 male and 79 female patients). Hemangioma was present in 137 patients (95.1%), varicosity in 110 (76.4%), and hypertrophy of the soft tissues or bones in 134 (93.1%). In most patients (71.5%) the disease involved one lower extremity. Diagnostic workup included roentgenogram to document limb length discrepancy, noninvasive arterial and venous evaluation, contrast venography, and nuclear magnetic resonance imaging. Most patients did well without treatment or with elastic compression only. Surgical treatment for the vascular malformation in KTS is rarely needed and it continues to be controversial. To evaluate the risks and benefits of vascular interventions, we examined in detail the clinical histories of nine patients who in the last decade underwent operation for a vascular malformation of the lower extremity. In seven patients we removed varicose veins or resected hemangioma of the lower extremity. Although none was cured, all five who underwent resection of varicose veins and one of the two patients who underwent resection of a hemangioma improved. Two additional patients, however, who underwent resection of varicose veins in another institution had worsening of the symptoms. In one patient we performed deep venous reconstruction for atresia of the superficial femoral vein, using the contralateral saphenous vein. Such operation in KTS has not been reported previously. The patient has a patent graft with a competent valve and clinical improvement 6 months after the operation. Although patients with severe chronic venous insufficiency, disturbing cosmetic appearance, or complications of hemangioma may benefit from surgical treatment, detailed preoperative imaging of the extremity and pelvis with magnetic resonance imaging and contrast venography is needed to decrease complications. Rarely, reconstruction for atresia or hypoplasia of the deep veins may be needed.

RESUMO

A maxillectomy defect creates a communication from oral cavity to nasal cavity that may extend to the orbit. Functional deglutition and speech problems with a significant soft tissue deficit ensue. This paper defines the reconstruction options for the spectrum of inferior partial maxillectomy defects to midface-orbital exonerations. Treatment protocols from maxillectomy patients treated in January 1991 to February 1996 at a major tertiary care institution were reviewed (n = 108). An ascension of care from dental obturator, nonvascularized graft, local flap, regional flap, and free tissue grafts (n = 28) is described. These data and experience were organized to provide a treatment algorithm to assist in presurgical planning for maxillectomy reconstruction.

RESUMO

We performed microvascular free-tissue reconstruction of extensive defects in the sino-orbital region in 11 patients. Reconstructions were immediate in 10 patients and delayed in one patient. There was loss of orbit in eight patients, maxilla in eight patients, cranial base in two patients, and skin and soft tissue of the face in six patients. Nine rectus abdominis flaps, one radial forearm flap, and one lateral arm flap were used. Palatal reconstruction with autologous tissue was successful in all patients. Cranial base repairs healed without sequelae or evidence of meningitis. Cosmetically, soft-tissue repair of facial skin was only satisfactory. For large defects, it was difficult to reconstruct the palate and facial soft tissue and to maintain nasal airway patency with a single microvascular procedure. Free-tissue transfers remain the safest and most versatile reconstructive procedure for massive sino-orbital defects after ablation of a tumor.

RESUMO

BACKGROUND AND HYPOTHESIS: Myocardial contrast echocardiography using second-generation agents has been proposed to study myocardial perfusion. A placebo-controlled, multicenter trial was conducted to evaluate the safety, optimal dose, and imaging mode for NC100100, a novel intravenous second-generation echo contrast agent, and to compare this technique with technetium-99m sestamibi (MIBI) single-photon emission computed tomography (SPECT). METHODS: In a placebo-controlled, multicenter trial, 203 patients with myocardial infarction > 5 days and < 1 year previously underwent rest SPECT and MCE. Fundamental and harmonic imaging modes combined with continuous and electrocardiogram-- (ECG) triggered intermittent imaging were used. Six dose groups (0.030, 0.100, and 0.300 microliter particles/kg body weight for fundamental imaging; and 0.006, 0.030, and 0.150 microliter particles/kg body weight for harmonic imaging) were tested. A saline group was also included. Safety was followed for 72 h after contrast injection. Myocardial perfusion by MCE was compared with myocardial rest perfusion imaging using MIBI as a tracer. RESULTS: NC100100 was well tolerated. No serious adverse events or deaths occurred. No clinically relevant changes in vital signs, laboratory parameters, and ECG recordings were noted. There was no significant difference between adverse events in the NC100100 (25.7%) and in the placebo group (17.9%, p = 0.3). Intermittent harmonic imaging using the intermediate dose was superior to all other modalities, allowing the assessment of perfusion in 76% of all segments. Eighty segments (96%) with normal perfusion by SPECT imaging also showed myocardial perfusion with MCE. However, a substantial percentage of segments (61-80%) with perfusion defects by SPECT imaging also showed opacification by MCE. This resulted in an overall agreement of 66-81% and a high specificity (80-96%), but in low sensitivity (20-39%) of MCE for the detection of perfusion defects. CONCLUSION: NC100100 is safe in patients with myocardial infarction. Intermittent harmonic imaging with a dose of 0.03 microliter particles/kg body weight can be proposed as the best imaging protocol. Myocardial contrast echocardiography with NC 100100 provides perfusion information in approximately 76% of segments and results in myocardial opacification in the vast majority of segments with normal perfusion as assessed by SPECT. Although the discrepancies between MCE and SPECT with regard to the definition of perfusion defects requires further investigation, MCE with NC 100100 is a promising technique for the noninvasive assessment of myocardial perfusion.

RESUMO

Intrathoracic infections associated with infection, leakage, or bleeding of the airway, lung parenchyma, esophagus, heart or great vessels is a life-threatening situation that luckily is infrequently seen. Failure to control these infections with the usual techniques can often be attributed to the presence of persistent pleural space, continuing empyema or bronchopleural fistula. Intrathoracic transposition of extrathoracic skeletal muscle in these situations offers an effective of management. Our experience has been possible because of the continued integrated effort with our thoracic surgical colleagues. We have found the team approach to work best and will continue to use it.

RESUMO

We have presented a transparent, inexpensive, rigid dome that allows a window to the wound, humidity chamber effect to continuously observe difficult skin-grafted wounds or free-tissue transfers allowing constant monitoring by visualization. The dome is inexpensive because it is simply a discarded breast implant package.

RESUMO

The histologic features of the Merkel cell and the pathologic characteristics of the Merkel cell tumor are described. From a literature review, 68 cases are examined; 23 cases that have been followed up accurately are presented from the Mayo Clinic. A representative case is used to demonstrate the problems of diagnosis and suggested treatment. The latter should be wide local resection with removal of nodal metastases if present. When indicated, this should be followed up with radiation therapy. Chemotherapy is of little or no value. Survival rates are presented.

RESUMO

Nipple-areolar necrosis is a known and expected complication in a small percentage of patients undergoing subcutaneous mastectomy, especially with concomitant mastopexy or in smokers. Impending ischemia or congestion of the areola can often be ameliorated by simple maneuvers such as suture release. When full-thickness necrosis occurs, conservative management with essential debridement, dressings, and careful wound hygiene alone will often yield a surprisingly good result, requiring little or no revisional surgery.

RESUMO

Angioleiomyomas are rare smooth-muscle tumors that occur anywhere in the body. We present the case of a 46-year-old woman with a 3-year history of a painless angioleiomyoma in the right-hand fourth web space with the typical histologic features of tortuous vascular channels and thick muscular walls. In the 39 cases of angioleiomyoma of an extremity treated at the Mayo Clinic, we found a male-to-female ratio of 1:2.2, a mean age of 52 years, and pain as the presenting symptom in 67 percent of the patients. The lesions usually were less than 1 cm in diameter, and they decreased significantly in size with increasing patient age. Simple excision was curative. Angioleiomyoma should be considered in all patients with nodular lesions of an extremity.

RESUMO

The utility of pedicled muscle flaps transposed into the thoracic cavity to reconstruct complex intrathoracic defects has been well documented. However, in some patients, local chest-wall muscles have already been either sacrificed or transected by previous thoracotomies and are not available for reconstruction. In these patients, we have successfully employed microvascular techniques to transfer distant muscle flaps into the thoracic cavity. Seven patients with complex intrathoracic defects were reconstructed with three latissimus dorsi, one omental, and three rectus abdominis free flaps. In each case, the microvascular anastomosis was extrathoracic, with the flap transposed into the thoracic cavity. Each of the flaps was revascularized successfully. Four of the five bronchopleural fistulas were sealed, with the remaining patient continuing to demonstrate a reduced but persistent air leak. No infections were encountered, and each flap transfer resulted in a healed wound. When local muscle flaps are not available to reconstruct complex intrathoracic wounds, microvascular transfer of distant muscle flaps can provide abundant well-vascularized tissue for reconstruction of any portion of the thoracic cavity. Versatility is afforded in flap selection and recipient vessel site location, making this technique an important option in the treatment of these difficult wounds.

RESUMO

The use of vascularized bone grafts to reconstruct extremity and mandibular defects is now commonplace in reconstructive surgery. Fibula, scapula, iliac crest, rib, and metatarsal as well as the radial forearm osseocutaneous flaps have all been utilized for this purpose. Troublesome spiral fractures of the distal radius are the most common fractures associated with the use of the distal radius as a vascularized bone-graft donor site. This study was proposed to investigate the effect of donor-site bone loss on the strength of the radius under torsional (rotational) loading. Previous clinical series and experimental studies have not examined this aspect of distal radius loading after harvesting the bone graft. Fifty pairs of sheep tibiae were utilized in the experiment. Five pairs were used in a pilot study and 45 pairs were used in the main experiment. Five pairs of human radii were used for the control in the pilot study. The pilot study attempted to make a comparison between the human radius and the sheep tibia for experimental purposes. For the biomechanical study of donor-site defects, four study groups were examined with random assignment and matched pairs. The control group (group 1) had no alteration to the bone. Each test condition included five matched pairs of sheep tibiae. Experiment 1 compared the difference in the depth of the osteotomy defect. In doing this, one-third of the total length of the bone was removed in each of the following specimens to include (1a) 30 percent of the cross-sectional area of the total bone, (1b) 37 percent of the cross-sectional area of the total bone, and (1c) 50 percent of the cross-sectional area of the total bone. In experiment 2, the osteotomy shape was varied. Instead of the ends of the cuts being squared, the ends were beveled or rounded. Experiment 3 compared different lengths of bone removed in the osteotomy defect and included the following: In experiment 3a the diameter of the sheep tibia was measured at the incisura fibularis. This dimension was one diameter of bone, and a one-diameter length of bone was removed. In experiment 3b, a two-diameter length of bone was removed. In experiment 3c, a three-diameter length of bone was removed. In experiment 3d, a four-diameter length of bone was removed.(ABSTRACT TRUNCATED AT 400 WORDS)

RESUMO

The infection rate for total-hip arthroplasty is around 1 percent. This small group is usually managed by complete removal of the prosthesis and the cement and closure over suction catheters to "collapse" the wound and eventually achieve a girdlestone arthroplasty. Occasionally, there are patients who have a persistent draining wound after this treatment and repeated efforts at wound closure. We present 27 patients who had recalcitrant, noncollapsible wounds of the hip that were present for many months to years. Twenty-eight cases of infected total-hip arthroplasties that did not respond to removal of the prosthesis and cement and closure were seen by the authors between January of 1977 and December of 1988. One patient had bilateral involvement. Average age was 64 years (range 33 to 79 years). There was an average of 4.2 previous surgical attempts at closure (range 1 to 21). Staphylococcus aureus was the most common organism, but the infections were virtually all multiple. Thirty-three muscles were utilized in 27 patients. The rectus femoris was used in 23 cases, the vastus lateralis in 8, tensor fasciae latae in 1, and combined latissimus dorsi-serratus anterior free-tissue transfers were carried out in 2. Multiple combinations of transpositions and free flaps were utilized. Follow-up ranged from 1 to 10 years, with an average of 6.4 years. Eighteen patients were ambulatory with minor degrees of pain, five ambulated with a cane, seven ambulated with a walker, six ambulated with crutches, and four ambulated unassisted, all of whom had reimplantation of their hip arthroplasty at least 12 months following the muscle flap procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

Controversy exists in the literature regarding reconstruction of the radial artery after elevation of the radial forearm flap. The literature suggests that reconstructing the radial artery with a vein graft is an important aspect in the use of this flap. In our experience, this has never been performed with no sequela. We examined 13 consecutive patients who underwent radial forearm flaps for head and neck reconstruction over a 28-month period. The patients were examined and questioned about the function of their upper extremities in hope of evaluating the postoperative vascular status in each. Median follow-up was 6 months, with a range of 1 month to 24 months. No patient had preexisting trauma or congenital abnormality of either arm, so that the nondonor arm could be considered as a control for each patient. Evaluation consisted of history and physical examination. The following parameters in each patient were carefully accumulated: grip strength, cutaneous blood flow measured by using a laser Doppler flowmeter, transcutaneous oxygen levels, digital/brachial blood pressure ratios, cutaneous temperature from thumb/index and thumb/small pinch, and rapid rewarming at 1-minute and 5-minute intervals after cold immersion for 2 minutes. The radial forearm flap was elevated in each patient in the nondominant extremity. Grip strengths ranged from 19 to 77 kg, with a median of 30 kg. Early rewarming of the thumb/index was also an average of 1.5 degrees less than the temperature in the control arm and was statistically significant to (p = .01).(ABSTRACT TRUNCATED AT 250 WORDS)
