Biomechanics of the golf swing in players with pathologic conditions of the forearm, wrist, and hand

Golf is an activity generally stressful to the hands and wrists and particularly can produce increasing symptoms in players with underlying problems such as hand and wrist arthritis or tendinitis. The purpose of this study was to quantitate wrist motion and club head/ball impact force in subjects with pathologic conditions of the hand, wrist, or forearm, within a laboratory environment. A regular straight-handled golf club was compared to a new BioCurve handle design that has a 19 degrees ulnar bend. We measured and compared the effect of the two grips on wrist motion, club head velocity, ball impact force, ball impact location, and isometric torsional strength in 20 subjects who had a variety of upper extremity disorders. This data was then compared to data collected in an identical fashion from golfers without such conditions. The results of our study show that there were no differences related to club handle design on impact force or impact location, club head velocity, or club head path and face angle. Wrist kinematic differences were minimal between handle designs. The differences that were significant (P less than 0.05) centered around the decreased ulnar deviation of the left hand that resulted when subjects used the BioCurve handle design, which also allowed greater resistance to torque than the straight grip club. In addition to collecting objective data, we asked subjects for their opinions of the two grips. As a whole, the normal group and the group with pathologic conditions noted more comfort, improved grip, and less shock transmission with the BioCurve handle.

Colposcopic assessment in microinvasive carcinoma of the cervix

Forty of the 87 patients with microinvasive carcinoma (MIC) of the uterine cervix who underwent surgery were diagnosed colposcopically and the results were compared with the cytological and histological diagnoses. The cytology showed preinvasive carcinoma in 20 (50.0%) patients and invasive carcinoma in 19 (47.5%) patients. A correct colposcopic diagnosis was made in nine (22.5%) patients as having microinvasive carcinoma, 21 (52.5%) patients preinvasive carcinoma and eight (20%) patients invasive carcinoma, to sum up accuracy rate as 32.1%. The abnormalities most commonly observed in colposcopy were mosaic, punctuation and white epithelium. In microinvasive carcinoma, the triad co-existed in 43% of the patients. Atypical vessels, characteristic of invasion, were found in only one third of the patients. Microinvasion, therefore, may not be evident on colposcopy alone. It is therefore necessary to apply cone biopsy, prior to definite therapy, to make an accurate assessment of the maximum depth and extent of the invasion prior to definitive therapy.

Effect of cisplatin chemotherapy on extracortical tissue formation in canine diaphyseal segmental replacement

The reconstruction of large bone and joint defects after the resection of malignant tumors remains a major challenge. Chemotherapy has significantly lowered the risk of metastasic disease, but complications associated with reconstructive techniques continue to result in late morbidity. In the present study, biomechanical torsion testing, gait analysis, and histomorphometric and scanning electron microscopic evaluations of 24 dogs were used to examine the effects of preoperative and postoperative administration of cisplatin on the biologic fixation of a porous-coated segmental replacement prosthesis. The chemotherapy consisted of four cycles of cisplatin administered at a dosage of 75 mg/m:² preoperatively or postoperatively. The healing was enhanced by use of an autogenous corticocancellous bone graft. The graft was placed evenly around the prosthesis and the adjacent femoral cortex. Mechanical analyses of torsional stiffness, yield strength, and maximum strength revealed no statistically significant differences between the groups at 12 weeks. Such lack of difference was mainly due to the penetration of highly organized fibrous tissue into the porous surface; this provided strong fixation of the implant to bone even in the absence of bone ingrowth. Although bone ingrowth into the prostheses was not affected, electron microscopic, histomorphometric, and radiologic analyses showed a clear difference in the formation of new bone around the prosthesis. Preoperative chemotherapy did not alter the formation of new bone, but specimens from animals treated postoperatively with cisplatin showed significantly less bone graft resorption and less new bone formation. Hence, the effect of cisplatin administration caused only a temporary delay, not a permanent effect, on extracortical capsule formation. The formation of extracortical bone and soft tissue might prevent debris-incised osteolysis and, therefore, prevent late complications by forming a tight capsule around the bone-prosthetic interface.     

Reoperative Thyroid Surgery

Reoperative thyroid surgery is an uncommon operation associated with a high complication rate. We retrospectively reviewed the data of 115 patients to study the incidence of complications after reoperative thyroid surgery. There were 107 women and 8 men (13.4:1.0) with an average age of 42.8 years (range 18–80 years). The most frequent indication for reoperation was completion thyroidectomy for a carcinoma identified by permanent sections (50 patients, 43.5%). Reoperative surgery was performed on 13 (11.3%) patients with recurrent thyroid cancer. The remaining 52 patients underwent reoperation for recurrent thyrotoxicosis (12 patients, 10.4%), recurrent nodular goiter (28 patients, 24.3%) or recurrent multinodular goiter (12 patients, 10.4%). Seven patients with recurrent nodular goiter and one patient with recurrent thyrotoxicosis underwent total thyroidectomy for the presence of malignancies that were identified by frozen sections. Overall, the interval between the initial and reoperative procedures ranged from 1 day to 33 years (2335 ± 272 days). The length of hospital stay was 5.8 ± 0.5 days. The length of time needed for reoperative thyroid surgery was 122.0 ± 6.2 minutes. There was no 30-day perioperative mortality. The postoperative complications consisted of transient hypoparathyroidism in six patients (5.2%), permanent hypoparathyroidism in two patients (1.7%), transient RLN palsy in 3 patients (2.6%), and permanent recurrent laryngeal nerve palsy in two patients (1.7%). Reoperative thyroid surgery can be performed safely with little morbidity to the patient.     

刺梨汁对慢性氟中毒的影响及机理研究

用高氟饲料喂养大鼠６个月，复制出慢性氟中毒模型，再自由饮用刺梨汁３个月，探讨刺梨汁对慢性氟中毒的影响及机理。结果表明：刺梨汁可明显改善氟中毒的一般状况，对已形成的氟斑牙影响不大，但可促进尿氟排泄，降低血清和骨氟含量及尿羟脯氦酸含量，提高血清中维生素Ｃ、维生素Ｅ和血清、肝、肾ＧＳＨ含量，增强血、肝、肾ＧＳＨ－Ｐｘ和ＳＯＤ活性，降低血清、肝和肾ＬＰＯ含量，降低尿γ－ＧＴ和血清ＧＰＴ活性及肝ＴＧ含量，提示：刺梨汁具有明显桔抗慢性氟中毒作用，其机理可能是通过促进尿氟排泄和抗氧化作用。     

颈动脉切除术的临床研究

目的 探讨颈部恶性肿瘤侵犯颈总动脉和I或颈内动脉以及颌面部难控制大出血时对颈总动脉和颈内动脉的外科处理方法及其并发症、后遗症的预防。方法 回顾性分析1990年－2000年行颈总或I和颈内动脉结扎、切除术的6例临床资料。结果 本组均为男性，年龄17－66岁。其中颈部复发性转移癌浸润颈总动脉、颈内动脉3例，鼻咽癌放疗后颈部溃疡侵犯颈总动脉1例，上颌骨中央性血管瘤大出血1例，鼻咽纤维轿管瘤术中、术后大出血1例。单纯结扎、切除颈总动脉4例，颈总及颈内动脉同时结扎、切除2例。经随访，术后短暂性肢体偏瘫2例，脑梗塞、永久性偏瘫1例，无任何并发症3例。无手术死亡病例。结论 颈动脉切除术对已累及颈动脉的颈部恶性肿瘤是一种有效的治疗手段，对于颌面颈难以控制的致命性大出血是一种有效的急救措施。单纯切除颈总动脉所产生的术后并发症的发生率比颈总动脉和颈内动脉同时切除低；而已先期或同时切除颈外动脉，出现并发症的机会更大。术后酌用抗凝或溶栓药物对于脑血栓、脑梗塞的防治作用有待进一步研究。
