1/94. An operative technique for recurrent shoulder dislocations in older patients.Recurrent anterior shoulder dislocation in the elderly is not as exceptional as it was once thought to be. That anterior shoulder dislocation in older patients is caused by a rotator cuff tear through the posterior mechanism is well accepted. However, in the subset of patients who have multiple recurrent or intractable dislocations develop, there may be combined pathologic conditions at work: large or massive rotator cuff tears together with anterior capsulolabral injuries such as a Bankart lesion or fracture of the glenoid rim. These patients have multiple recurrences because of disruption of both the anterior and the posterior stability mechanisms. We suggest a procedure that provides anterior stabilization with the capsular shift technique and that is supplemented by Bankart repair as necessary. The capsule transfer is performed superiorly and posteriorly to close the defect in the cuff. In this way a capsulodesis effect can be achieved that displaces the humeral head downward and produces active centering of the head in the course of abduction. Use of only the anterior capsule for the shift, and not the subscapularis tendon, does not compromise subscapularis function. Between 1990 and 1996, we used this technique to treat 16 patients older than 55 years of age with multiple recurrent anterior shoulder dislocation and massive rotator cuff tear. We report the results for the first 10 patients with a minimum follow-up of 2 years (range 2 to 7 years) and an average follow-up of 52 months. There were 7 excellent results, 2 good results, and 1 fair result according to the Rowe criteria. None of the patients had a recurrence of the dislocation. All the patients regained full or functional range of motion with stable shoulders, and most of them could perform activities of daily living without limitation. The average Constant score was 83%. This procedure appears to be successful in treating older patients with recurrent shoulder dislocation.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/94. Excision and radiotherapy for heterotopic ossification of the elbow.radiotherapy has a well-defined role in prophylaxis of recurrent heterotopic ossification of the hip, but has been described infrequently in other situations. This article reports the use of excision and low-dose external beam radiotherapy in three patients with heterotopic ossification of the elbow treated between February 1995 and September 1996. radiotherapy was delivered in a single fraction of 7-8 Gy within 48 hours postoperatively using opposed anteroposterior portals. After a median follow-up of 10.5 months, all three patients demonstrated a significant increase in range of motion without any evidence of recurrence. These results indicate adjuvant postexcision radiotherapy may be used for prophylaxis of recurrent heterotopic ossification of the elbow.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
3/94. Daily psychosocial stressors interfere with the dynamics of urine neopterin in a patient with systemic lupus erythematosus: an integrative single-case study.OBJECTIVE: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by flare-ups, the causes of which are not known. In accordance with new concepts in stress research, this study investigated whether daily psychosocial stressors interfere with immunological processes in SLE. Because such processes are unique to each individual, single-case design using time-series analysis (Box and Jenkins) was applied. methods: A 40-year-old woman with SLE (last flare-up September 1995) was interviewed initially to determine major life events and difficulties (using the life Events and Difficulties Schedule) in the previous 2 years. She was then observed for 63 days. urine neopterin, an immunological parameter demonstrated to parallel disease activity in SLE patients, was measured in daily overnight urine. Daily incidents were identified weekly by the Incidents and Hassles Inventory and independently rated. Intervening factors, including infections, medication, and lifestyle, were controlled. RESULTS: Retrospectively, data obtained from the life Events and Difficulties Schedule indicated that major life events and difficulties had preceded the patient's last flare-up in 1995. Although there were no clinical signs of SLE during this prospective study of 63 days, cross-correlational analyses revealed that "moderately" stressful incidents associated with higher levels of emotional irritation (lag 0: 0.271, p < .05) predicted an increase in urine neopterin the following day (lag 1: 0.441, p < .05). Moreover, a 7-day cyclicity in neopterin levels that corresponded to the weekly examinations and interviews was found. CONCLUSIONS: This study showed a causal relationship between psychosocial stressors and urine neopterin concentrations that may be related to SLE disease activity. Furthermore, the workability of an integrative approach using single-case design and time-series analysis in psychoneuroimmunology was demonstrated for the first time.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
4/94. Effects of a tendo-Achilles lengthening procedure on muscle function and gait characteristics in a patient with diabetes mellitus.STUDY DESIGN: Case report with repeated measures. OBJECTIVES: To describe the effects of a tendo-Achilles lengthening (TAL) and total contact casting (TCC) on wound healing, motion, plantar pressure, and function in a patient with diabetes mellitus, peripheral neuropathy, neuropathic ulcer, and limited dorsiflexion range of motion (DFROM). BACKGROUND: Limited DFROM has been associated with increased forefoot pressures and skin breakdown. A TAL was expected to increase DFROM and reduce forefoot pressures during walking, but the influence on muscle performance and function was unknown. methods AND MEASURES: The patient was a 42-year-old man with a 20-year history of type 1 diabetes (NIDDM) and a recurrent neuropathic plantar ulcer. Outcome measures were DFROM, isokinetic plantar flexor muscle peak torque, in-shoe and barefoot peak plantar pressure, physical performance test (PPT) score, and peak ankle and hip moments during walking obtained from an automated gait analysis. All tests were completed pre-TAL, 8 weeks post-TAL (after immobilization in a TCC), and 7 months post-TAL. RESULTS: The wound healed in 40 days. The TAL resulted in a sustained increase in DFROM (0 to 18 degrees). Plantar flexor peak torque was reduced by 21% 8 weeks after the TAL compared with the torque before surgery but recovered fully at 7 months. Seven months following TAL, in-shoe forefoot peak plantar pressure was reduced by 55%, barefoot pressure decreased by 14%, PPT score increased by 24%, peak ankle plantar flexor moment remained decreased by 30%, and the peak hip flexor moment increased by 41% during walking. CONCLUSION: For this patient, a TAL resulted in short-term deficits in peak plantar flexor torque, but a 7-month follow-up showed improvements in ankle DFROM, walking ability, and a decrease in forefoot in-shoe peak plantar pressure.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
5/94. Second-look arthroscopy with removal of bioabsorbable tacks.Eleven years after tearing her anterior cruciate ligament (ACL) (not reconstructed), a 36-year-old dancer reinjured her knee and required arthroscopic ACL reconstruction. At arthroscopy, the medial meniscus had a bucket-handle tear that was repaired by using three bioabsorbable tacks. The ACL was then repaired in the usual manner. Because of persistent posterior knee pain throughout her rehabilitation, we performed "second-look" arthroscopy 14 weeks after reconstruction. The meniscus had healed and was stable; however, tack motion was evident and the tacks were easily removed. Inspection of the tacks showed that the barbs had been resorbed. The patient recovered uneventfully, and pain-free flexion 28 days after surgery was 0 degrees-136 degrees. We believe this to be the first reported case demonstrating the early stages of tack degradation in meniscal repair.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
6/94. hyperthyroidism complicating asthma treatment.asthma is one of the most common chronic medical conditions. The usual treatment includes quick relief bronchodilator medications of the sympathomimetic class and controller medications that may include the long-acting inhaled bronchodilator salmeterol. Mild adverse cardiac and central nervous system effects are common with these medications, requiring modifications in dose or occasionally switching to a different medication. Both asthma and thyroid disease are common disorders that occasionally occur together. hyperthyroidism may exacerbate asthma. Many symptoms of hyperthyroidism are identical to the adverse effects of the commonly used inhaled bronchodilators and include tremor, nervousness, tachycardia, wide pulse pressure, palpitations, emotional lability, agitation, nightmares, aggressive behavior, and diarrhea. In this report we describe a patient with hyperthyroidism whose symptoms initially were thought to be adverse effects of the inhaled bronchodilator medications.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
7/94. Minimally invasive direct coronary artery bypass grafting using the saphenous vein in redo CABG.We describe a patient who underwent minimally invasive direct coronary artery bypass (MIDCAB), who had previously undergone coronary artery bypass grafting (CABG) through a median sternotomy with a left internal mammary artery (LIMA) graft to the left anterior descending artery (LAD) and a right gastroepiploic artery (GEA) graft to the posterior descending artery. MIDCAB was less invasive and was an effective alternative procedure for the second operation. Because the patient had no LIMA or GEA available for a graft because of prior use, we used a saphenous vein graft (SVG) for bypassing from the left subclavian artery to the coronary artery by MIDCAB via a left minithoracotomy. The left subclavian artery was selected as the proximal anastomotic site because this artery was less diseased and was easier to reach. The SVG-to-coronary artery anastomosis was facilitated by firm adhesion between the epicardium and the pericardium, which reduced the motion of the epicardium itself. These results suggest that the procedure is safe and promising in selected cases of redo CABG.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
8/94. Cronkhite-canada syndrome: report of two cases.Two cases of Cronkhite-canada syndrome are reported. In the first case, a 56-year-old woman had an adenoma of the colon, arising within the Cronkhite-canada polyps, which was removed by endoscopic polypectomy. This suggests possible neoplastic transformation of polyps in this syndrome. She achieved remission with corticosteroids, but the polyposis recurred (only in the stomach) 7 months after the remission. In the recurrent polyposis, corticosteroid therapy resulted again in complete remission, which has lasted for 5 years. In the second case, a 69-year-old man developed typical manifestations of the syndrome while under emotional stress. He had a past history of chronic pityriasis lichenoides, and serum antinuclear antibody was positive. These findings suggested a possible role of autoimmune response in the pathogenesis of the syndrome. Corticosteroids were also effective in this patient.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
9/94. Recurrent short-lasting headache associated with paroxysmal hypertension: a clonidine-responsive syndrome.The clinical syndrome of hypertension, headache, palpitation, diaphoresis, flushing, and emotional lability is classically associated with pheochromocytoma. Two patients are presented with this constellation of symptoms in whom investigations for pheochromocytoma were unrevealing. headache was the presenting and most prominent complaint, with daily episodes of short-lasting, intermittent, and paroxysmal attacks. Each paroxysm of headache was associated with a dramatic increase in systolic and diastolic blood pressure. After failure to control the labile fluctuations in blood pressure and headache with several classes of anti-hypertensive medications used in combination, a prompt and persistent response occurred after the administration of clonidine. The pathophysiology of this syndrome and the mechanism of clonidine action are reviewed in the context of a possible failure of the baroreceptor reflex.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
10/94. Chronic addiction relapse treatment: a study of the effectiveness of the high-risk identification and prediction treatment model. Part II. The HRIPTM case table, case study examples and questionnaire.The high-risk identification and prediction treatment model (HRIPTM) was developed to investigate the physiological and psychological conditions associated with the concept of negative emotional state, and to examine the origin and evolution of this condition in relation to addiction relapse. An in depth case study sample of n=30 was conducted within the context of an intensive outpatient addiction treatment program based on the HRIPTM. The HRIPTM investigates the nature of problematic repetitive behavior patterns originating in the childhood developmental period, the individual nature of negative emotional state in relation to these patterns and their evolution, and their influence on addiction vulnerability and addiction relapse. The preliminary study upon which this model was based emphasized the importance of developing methods for accumulating information that pinpoints lifespan experiences associated with the origin of problematic behaviors, the level of emotional intensity factors associated with behavior pattern construction and development, and level of associated risk potential as it manifests in each individual case.Recent neuroscientific studies into the early developmental process are producing increased evidence of the enormous influence of this period on later developmental processes. Addiction, in itself a developmental process, may be more influenced by pre-addiction factors than previously assumed. This model addresses those influences. The study was conducted to determine whether or not information that arises from the HRIPTM increases the patient's and clinician's ability to address addiction relapse more effectively. As a result of completion of the HRIPTM program, the sample n=30 reported gained ability to address recovery processes more effectively. The 12-question HRIPTM Questionnaire instrument, when tabulated, revealed that of the 360 total responses, less than 2% disagreed that ability had been gained in all suggested areas defined in the questionnaire. Over 98% agreed or strongly agreed that ability had been gained in the defined areas.- - - - - - - - - - ranking = 3keywords = motion (Clic here for more details about this article) |
