Etiology is unknown, even if immunological, genetic and environmental factors are involved. The majority of CD patients require surgery during their lifetime due to progressive bowel damage, but, even when all macroscopic lesions have been removed by surgery, the disease recurs in most cases. Postoperative management represents therefore a crucial mean for preventing recurrence. Several drugs and approaches have been proposed to achieve this aim. Endoscopic inspection of the ileocolic anastomosis within 1 year from surgery is widely encouraged, given that endoscopic recurrence is one of the greatest predictors for clinical recurrence. A strategy should be planned only after stratifying patients according to their individual risk of recurrence, avoiding unnecessary therapies when possible benefits are reduced, and selecting high-risk patients for more aggressive intervention.展开更多

Methods: 220 adults with chronic sinusitis(20 as control) were classified into pre- and post-operative groups, and categorised according to its type of sinusitis. Swab specimens were taken from three different sites of ostiomeatal complex in each individual, and cultivations and identifications of aerobes, anaerobes and fungi were performed simultaneously. The microecosystem was analysed. Results: Cultured aerobes belonged to 30 species from 13 genera, anaerobes species, and fungi 3 major species, most of which have none or less virulence. The difference of mi-croecological status between type Ⅰ and Ⅱ was not significant (P > 0.05). Aerobic culture rates between preoperative group and control group had significance(P < 0.01);culture rate descended in postoperative group while the difference was not significant compared to preoperative group (P > 0. 05); difference of rate of same aerobic culture from three sites (RSAC) , which reflects the microecological integrity of OMC, between preoperative and control group was significant (P < 0.01), while was not between postoperative group and control one(P > 0. 05). Taking fungi into account, differences among all groups had no significance(P>0.05); anaerobes were rare in all groups. Conclusion: Being a microecosystem under normal condition, ostiomeatal complex is relatively clean and exists as a whole space. Chronic inflammations separate different parts of which from each other with multimicrobial existence.FESS reverses separation of the microecosystem and rebuild it as a whole again, thus promote the recovery.展开更多

Methods Moderate to advanced chronic periodontitis ( CP) was studied in 36 diabetes mellitus (DM) patients classified as 20 with high and fluctuating blood glucose level (DM-H) and 16 with relatively low and stable blood glucose level (DM-L). 28 non-DM CP patients acted as controls (Non-DM). Plaque index (PlI) , gingival index (GI) , bleeding on probing (BOP) , probing depth (PD) and clinical attachment loss (AL) of all patients were recorded at 6 sites on each tooth at the baseline and 1, 3 and 6 months after oral hygiene instruction (OHI), scaling and root planing. Results It was found that the short-term effect of non-surgical periodon-tal procedure had resulted in significant resolution of gingival inflammation and pronounced reduction in pocket depth and gain of attachment loss in both DM and Non-DM CP patients. Conclusion The pilot study suggested that non-surgical periodontal treatment allowed for favorable treatment responses in a group of Chinese diabetic subjects with chronic periodontitis and that their various profiles of blood glucose did not influence the short-term healing response to OHI, scaling and root planning.展开更多

Should we adopt conservative or operative measures at first presentation？ It is not clear but most of the evidences are in favour of conservative management. We present our expe- rience in managing these patients surgically. Methods： We present a prospective series of eight cases of chronic Rockwood type 3 acromioclavicular joint disruptions treated surgically. Anatomical reconstruction of the coracoclavicular ligament was done by artificial braided polyester ligament prosthesis： Results： All the patients were able to perform daily activities from an average of the 14th postoperative day. All patients felt an improvement in pain, with decrease in ave- rage visual analogue scale from preoperative 6.5 points （range 3-9 points） to 2.0 points （range 0-5 points）, Constant score from 59% to 91% and American Shoulder and Elbow Surgeons shoulder score from 65 to 93 points postoperatively. These results improved or at least remained stationary on midterm follow-up, and no deterioration was recorded at an average follow-up of 46 months. Conclusion： This midterm outcome analysis of the artificial ligament prosthesis is the first such follow-up study with prosthesis. Our results are encouraging and justify the further use and evaluation of this relatively new and easily reproducible technique.展开更多

Methods： From January 2004 to December 2009, 398 patients with CSDH, 338 males and 60 females （male/ female=5.63/1）, received burr-hole craniotomy in our hospital. The median age was 60 years with the mean age of （58.1± 18.1） years, （65.0±14.5） years for females and （57.0± 8.2） years for males. Trauma history was determined in 275 patients （69.1%）. Burr-hole craniotomy was performed under local anesthesia in 368 patients and general anesthesia in 30 patients. CSDH was classified into 3 groups according to the density on CT scan. Clinical data concerning etiologies, symptoms and signs, concomitant diseases, diagnosis, therapies and outcomes were investigated retrospectively. Patients＇ neu- rological status on admission and at discharge was also classified to judge the outcomes. Results： Generally, trauma history showed few dif- ferences between those over 60 years old and under 60 years old, but showed obvious differences when gender was taken into account. Totally 123 male patients （60.0% of 204 cases） suffering from head injuries were under 60 years, whereas 35 female patients （85.4% of 41 cases） with trauma histories were over 60 years. The duration from trauma to appearance of clinical symptoms was （84.0±61.7） days （range, 0-1493 days）. Traumatic accident was the leading etiology, other accompanying diseases such as cerebral vascular disease, hypertension, etc, were also predisposing factors. Commonly, the elderly presented with hemiplegia/ hemidysesthesia/hemiataxia and the young with headache. Most CSDH patients （95.6%） treated with burr-hole cran- iotomy successfully recovered. However, postoperative complications occurred in 17 cases, including recurrence of CSDH in 15 cases, subdural abscess in 1 case and pneumonia in 3 cases. Conclusion： Burr-hole craniotomy is an easy, efficient and reliable way to treat CSDH.展开更多
