Informing is an initiative behavior of medical staff in their clinical practice. Besides, informing is a key principle of informed consent. The number of cases of infringing upon patient’s informed consent is increasing because of the underestimate or ignorance of the obligation of informing. This paper discusses the concept, significance, content, and procedure of informing as well as the relationship between informed consent and informing.
Objective To assess the effectiveness of arthroscopic capsular release to treat primary severe frozen shoulder through trans cuff portal. Methods Between June 2012 and January 2015, 28 patients with primary severe frozen shoulder were enrolled in the study. There were 8 males and 20 females with an average age of 57 years (range, 42-81 years). The left shoulder was involved in 16 cases and the right one in 12 cases. The mean disease duration was 11 months (range, 7-21 months). Six patients had diabetes. All patients underwent arthroscopic capsular release by trans cuff portal. The range of motion (ROM) of the shoulder were measured at preoperation and at 6 weeks and 24 months after operation; the scores of American Shoulder and Elbow Surgeons (ASES) and visual analogue scale (VAS) were used to evaluate the shoulder function and pain. Results Primary healing of incision was obtained, and no complications of infection, shoulder instability, and nerve injury were found. All patients were followed up 24 months. Pain of the shoulder was obviously relieved; VAS score was significantly lower at 6 weeks and 24 months after operation than preoperation (P<0.05), and at 24 months than 6 weeks (P<0.05). ROM of the shoulder and ASES score at 6 weeks and 24 months after operation were significantly increased when compared with preoperative ones (P<0.05); significant difference was found in ROM of forward flexion and external rotation and the ASES score between at 6 weeks and 24 months (P<0.05). And internal rotation in-creased from trochanter (9 cases), hip (6 cases), sacrum (7 cases), and L4 vertebral level (6 cases) before operation to the T12-T6 vertebral level at 6 weeks and 24 months after operation, which were close to normal side. Conclusion Arthroscopic capsular release through trans cuff portal is an effective and safe management for primary severe frozen shoulder.
Objective To investigate the diagnostic significance of fine needle aspiration cytology (FNAC) combined with BRAFV600E gene detection in the diagnosis of cervical lymph node metastasis of thyroid cancer. Methods Atotal of 140 patients with suspected cervical lymph node metastasis of thyroid cancer were collected as the research objects, and all patients were given ultrasound-guided FNAC and detection of BRAFV600E gene. The significance of the diagnosis was analyzed according to the gold standard after pathological examination. Results All the 140 patients underwent surgical treatment. For FNAC, the sensitivity was 63.6% (84/132), the specificity was 100% (8/8), the accuracy was 65.7% (92/140), the positive predictive value was 100% (84/84), and the negative predictive value was 14.3% (8/56). For detection of BRAFV600E gene, the sensitivity was 84.8% (112/132), the specificity was 100% (8/8), the accuracy was 85.7% (120/140), the positive predictive value was 100% (112/112), and the negative predictive value was 28.5% (8/28). For FNAC combined with BRAFV600E gene detection, the sensitivity was 90.9% (120/132), the specificity was 100% (8/8), the accuracy was 91.4% (128/140), the positive predictive value was 100% (120/120), and the negative predictive value was 40.0% (8/20). The area under curve of receiver operating characteristic for FNAC, detection of BRAFV600E gene, and FNAC combined with BRAFV600E gene detection were 0.818, 0.924, and 0.955, respectively. Conclusion FNAC combine with BRAFV600E gene detection improves the accuracy of neck lymph node metastasis in patients with thyroid cancer, which is worthyof performed.
ObjectiveTo study the changes of bacterial flora after a series of preoperative oral disinfection and the postoperative recovery of patients with craniovertebral junction disorders who were treated with transoral approach operations. And to provide a theoretical basis for the prevention of postoperative complications such as infection.MethodsThe clinical data of 20 cases with craniovertebral junction disorders and treated with transoral approach operations between October 2009 and May 2010 were analyzed. There were 8 males and 12 females, aged 2-66 years (median, 34.5 years). According to the classification of American Spinal Injury Association (ASIA), there were 4 cases of grade B, 8 of grade C, 6 of grade D, and 2 of grade E. The Japanese Orthopedic Association (JOA) score was 10.3±3.0. The mucosa samples of the posterior pharyngeal wall were sent for bacteria culture. These samples were collected by sterile cotton swabs at four crucial points including 3 days before operation/before gargling (T1), 3 days after continuous gargling by chlorhexidine acetate/after anesthesia intubation on the day of operation (T2), after intraoperative cleaning and washing of the mouth (T3), and after intraoperative iodophor immersion for 5-10 minutes (T4). The microflora was stained by means of smear and further counted after an investigation by microscope. The ASIA classification and the JOA scores were applied to evaluate the postoperative nerve function of the patients. A regular reexamination of cervical vertebra with X-ray film, CT, and MRI was conducted after operation to evaluate the reduction of atlantoaxial dislocation, internal fixation position, bone graft fusion, inflammatory lesion, and tumor resection in the craniovertebral junction.ResultsAfter a series of oral disinfection, the mucosa of the posterior pharyngeal wall of all the patients was in a sterile state, which was considered as type Ⅰ incision. All these 20 patients were treated with successful operations, without any intraoperative injury in vertebral artery and spinal cord, or any postoperative complications such as plate loosening, incision infection, or intracranial infection. All the patients were followed up 3-23 months, with an average of 5.15 months. The symptoms such as neck pain, limb numbness and weakness, neural symptoms, etc. were improved to different degrees after operation. The JOA score was improved to 13.4±1.9 at 3 months after operation, showing significant difference when compared with preoperative score (t=8.677, P=0.000); and the atlantoaxial joints had been fused. At last follow-up, the ASIA grades were improved when compared with those before operation. ConclusionIt is safe and effective to cut the posterior pharyngeal muscle layer and implant internal fixation by means of transoral approach in the treatment of craniovertebral junction disorders.
Objective To summarize the clinical characteristics, differential diagnosis, and treatment methods of finger flexion contracture caused by three kinds of forearm flexor diseases. Methods Between December 2008 and August 2021, 17 patients with finger flexion contracture were treated, including 8 males and 9 females, aged 5-42 years, with a median of 16 years. The disease duration ranged from 1.5 months to 30 years, with a median of 13 years. The etiology included 6 cases of Volkmann’s contracture, all of which were flexion deformity of the 2nd to 5th fingers, accompanied by limitation of thumb dorsiflexion in 3 cases and limitation of wrist dorsiflexion in 3 cases; 3 cases of pseudo-Volkmann’s contracture, including 2 cases of flexion deformity of middle, ring, and little fingers, and 1 case of flexion deformity of ring and little fingers; 8 cases of ulnar finger flexion contracture caused by forearm flexor disease or anatomical variations, all of which were flexion deformity of middle, ring, and little fingers. Operations such as slide of flexor and pronator teres origin, excision of abnormal fibrous cord and bony prominence, and release of entrapped muscle (tendon) were performed. Hand function was evaluated according to WANG Haihua’s hand function rating standard or modified Buck-Gramcko classification standard, and muscle strength was evaluated according to British Medical Research Council (MRC) muscle strength rating standard. Results All patients were followed up 1-10 years (median, 1.5 years). At last follow-up, 8 patients with contracture caused by forearm flexor disease or anatomical variations and 3 patients with pseudo-Volkmann’s contracture achieved excellent hand function, with muscle strength of grade M5 in 6 cases and grade M4 in 5 cases. One patient with mild Volkmann’s contracture and 3 patients with moderate Volkmann’s contracture without severe nerve damage had excellent hand function in 2 cases and good in 2 cases, with muscle strength of grade M5 in 1 case and grade M4 in 3 cases. Two patients with moderate or severe Volkmann’s contracture had poor hand function, with 1 case of muscle strength of grade M3 and 1 case of grade M2, which improved when compared with those before operation. The overall excellent and good rate of hand function and the proportion of patients with muscle strength of grade M4 and above were 88.2% (15/17), respectively. ConclusionThe finger flexion contracture caused by different etiology can be differentiated by analyzing the history, physical examination, radiographs, and intraoperative findings. After different surgical treatments, such as resection of contracture band, release of compressed muscle (tendon), and downward movement of flexor origin, most patients have a good outcome.
【Abstract】 Objective To study a new method of alveolar cleft bone graft repair. Methods From April 2005to August 2006, 26 cases (30 sides) of alveolar cleft were treated with trabecular substance of self-il ium combined with the decalcified dentinal matrix of human (DDM). There were 16 males and 10 females, aged 6-12 years. Unilateral alveolar cleft was involved in 22 cases, bilateral alveolar cleft in 4 cases. All cases were accompanied by nasal wing collapse, 5 by deciduous tooth retention, 3 by malposed teeth and 1 by tooth deformity. Anterior occlusal radiographs and panoramic oral radiographs were taken to observe union and bone absorption before and after operation. Results Twenty-three patients achieved heal ing by first intention, oronasal fistulas were closed successfully. Infection occurred in one bilateral alveolar cleft case and bone tissue exposure in 2 cases. Wound healed by rinse or dressing change and inunction with MEBO. The X-ray films after operation showed bone bridge formation in the alveolar cleft. The stabil ity and continuity of body of maxilla were resumed. Four cases (6-9years old) were observed 6.5 months, 22 cases (9-12 years old ) were observed 8.6 months. According to Bergland for evaluation,the X-ray films after 3 months of operation showed 16 cases (16 sides) in class I (53.3%), 7 cases (8 sides) in class II (26.7%),2 cases (4 sides) in class III (13.3%), and 1 case(2 sides) in class IV (6.7%). The overall survival ratio of alveolar bone grafting was 93.3%, and the cl inical success ratio was 80%. Conclusion The DDM is good in alveolar cleft bone graft repair. It is better than using self-il ium only cl inically.
