ABSTRACT
Objective:To compare the technique between concave distraction and convex resection in the treatment of congenital cervicothoracic scoliosis and evaluate its curative effect.Methods:Data of congenital cervicothoracic scoliosis patients from January 2010 to January 2020 were collected, among which 5 were males and 3 were females. The patients' age was 12.5±4.5 years old (range 6-20 years old). One case had C 7 wedged vertebra, 4 cases had T 1 hemivertebra and unbalanced vertebra, 2 cases had T 2 hemivertebra and 1 case had fused facet joint and wedged lamina in T 1. All patients had different degrees of vertebra fusion. Convex resection technique (one stage anterior and posterior combined hemivertebrae resection and annular osteotomy) was used to treat 4 cases before 2015; Concave distraction technique (A combination of anterior and posterior release, intervertebral space and facet space distraction, cage placed and fusion) was used to treat 4 cases after 2015 and 2 of them had 2 segments distraction. Perioperative neurological, vascular and wound related complications were recorded. The main parameters were structure Cobb angle, cephalic and caudal compensatory Cobb angle, mandibular incline, neck tilt, shoulder balance and head shift were measured pre-operation, post-operation and at the last follow-up. Results:All patients' surgeries were completed successfully. In convex resection group, the duration of surgery was 201±100 min (range 113-300 min) per vertebra, the estimated blood loss was 294±153 ml (range 100-450 ml) per vertebra, the hospital stay was 14±3 d (range 11-18 d) and follow up time was 51±11 months (range 36-60 months). In concave distraction group, the duration of surgery was 117±14 min (range 101-129 min) per vertebra, the estimated blood loss was 119±36 ml (range 85-167 ml) per vertebra, hospital stay was 17±3 d (range 14-20 d) and follow up time was 28±21 months (range 12-60 months). Convex resection group had longer operation time and more blood loss per vertebra than concave distraction group. In convex resection group, structural Cobb angle was 45.1°±21.0° pre-operation and 22.7°±15.3° post-operation, which was corrected significantly ( Z=6.53, P=0.038). The correction rate was 54.8%±30.9%. Cephalic compensatory Cobb angle was 22.1°±8.2° pre-operation and 8.2°±5.8° post-operation, which was corrected significantly ( F=6.01, P=0.049). The correction rate was 66.8%±15.1%. Mandible incline was 7.8°±3.1° pre-operation and 3.5°±1.5° post-operation, which was corrected significantly ( F=8.02, P=0.018). The correction rate was 51.0%±29.7%. In concave distraction group, structural Cobb angle was 32.2°±27.2° pre-operation and 16.3°±16.7° post-operation, which was corrected significantly ( F=7.43, P=0.024) . The correction rate was 59.0%±24.7%. Caudal compensatory Cobb angle was 18.9°(17.2°, 32.1°) pre-operation and 9.5°±10.3° post-operation, which was corrected significantly ( Z=6.00, P=0.049). The correction rate was 64.0%±24.1%. Clavicle angle was 3.9°±2.3° pre-operation and 0.3°±0.4° post-operation, which was corrected significantly ( F=1.75, P=0.040). The correction rate was 97.0% (48.5%, 99.8%). There was no significant difference in the correction rate of all radiographic parameters between the two groups. At the last follow-up, the patients' appearance of head, neck and shoulder were improved compared with those before surgery. In convex resection group, 2 patients showed nerve root stimulation symptoms postoperatively on convex side. One patient developed C 5 nerve root palsy which weakened deltoid muscle and the other patients presented with reduced triceps muscle strength. In concave distraction group, one patient developed C 5 nerve root palsy on convex side. All these symptoms recovered by conservative treatment 3 months after operation. Conclusion:It is safe and effective to treat congenital cervicothoracic scoliosis with convex resection technique and concave distraction technique. The concave distraction technique has the advantages of more safety, less operating time, less blood loss and easier to perform and has a wider application prospect.
ABSTRACT
Objective:To explore the safety, feasibility, and short-term outcome ofdistraction on the concave side in the treatment of patients with congenital cervical scoliosis.Methods:Between August 2015 and December 2019, 11 patients with congenital cervical scoliosis underwent distraction technique on concave side, among which 5 were males and 6 were females. Age was 9.9±3.1 years old (range 6-16 years old). The primary cervical spine deformity was hemi-vertebra with different degrees of vertebra fusion. 7 cases were in C 3, 3 cases were in C 4 and 1 case was in C 5. Anterior-posterior combined approach was used. Firstly, discectomy and soft tissue release on concave side were made through anterior approach, then distraction on concave side and fusion with internal fixation were made through posterior approach and at last fixation and fusion in anterior approach were made. In this study we measured structure Cobb angle, compensatory Cobb angle, mandibular incline, shoulder balance and the angle difference of trapezius muscle preoperation and post operation. Perioperative neurological,vascular and wound related complicationswere recorded. Results:All patients' surgeries were completed successfully. Eight patients received single site distraction and 3 patients received distraction in two sites. The duration of surgery was 466±141 min (range 150-659 min), the estimated blood losswas 387±191 ml (range 100-660 ml) and follow up time was 12.2±9.5 months (range 3-24 months). Structural Cobb angle was 28.9°±13.1° pre-operation and 7.4°(3.0°, 27.7°) post-operation at 3 months, which was corrected significantly ( Z=-2.934, P=0.003). The correction rate was 58.1±26.1% (range 18.8%-97.6%). Structural Cobb angle was 13.2°±12.3°at 1 year post operation and had no significant difference compared with 3 months post operation ( t=1.960, P=0.107). Compensatory Cobb angle was 18.3°±6.1° pre-operation and 9.4°±7.3° post-operation at 3 months, which was corrected significantly ( t= 5.071, P<0.001) and the correction rate was 51.3%±28.3% (range 2.4%-94.7%). Compensatory Cobb angle was 8.9°±7.7° at 1 year follow up and was corrected significantly ( t=5.253, P=0.003) compared to 3 months after surgery and the correction rate was 61.4%±26.9%. Two patients developed C 5 nerve root dysfunction and 1 patient developed numbness on the index and middle fingers after surgery. All of them occurred on the concave side and recovered by conservative treatment. Conclusion:The application of distraction on the concave side in the treatment of congenitalcervical scoliosis is with good feasibility and clinical safety. Short-term follow-up showed excellent resultswith a promising future.
ABSTRACT
Objective To evaluate the efficacy of mesalazine combined with compound glutamine in the treatment of radiation related enteritis. Methods Ninety-four patients were randomly divided into the observation group and the treatment group, with 47 cases in each group. Patients in control group were given compound glutamine orally. On the basis of compound glutamine, patients in the observation group was added mesalazine orally.

ABSTRACT
This paper discussed the importance of prevention of diabetic foot ulcers and our institution's protocol for prevention, reviewing the existing evidence in the literature regarding the effectiveness of the preventive approach. Diabetes mellitus is the second most significant cause of disease in Singapore after ischaemic heart disease. National University Hospital, Singapore, adopts a two-pronged strategy for the management of diabetic foot ulcers. The most important strategy is prevention, and education is key. Education should mainly be directed at patients and caregivers, but also professionals (general practitioners, allied health professionals and nurses) so that they can effectively educate patients and caregivers. Patient education includes care of diabetes mellitus, care of the foot and use of appropriate footwear. Patients also tend to have poor foot hygiene. Annual foot screening for diagnosed diabetics plays an important role. However, prolonged and sustained government intervention is necessary to provide education and screening on a national scale.
ABSTRACT
Objective To investigate the risk factors for colorectal cancer adjuvant chemotherapy induced leucopenia. Methods The basic clinical data of 108 patients with colorectal cancer who had received radical operation and adjuvant chemotherapy were retrospectively evaluated. The patients were divided into two groups: normal white blood cell group (39 patients) and leucopenia group (69 patients). The data were analyzed with SPSS 22.0 software, t test, χ2 test , univariate analysis and multifactor Logistic regression analysis, and analysis of variance to investigate the risk factors for colorectal cancer adjuvant chemotherapy induced leucopenia. Results Univariate analysis revealed that the female patients and the ones who received radiotherapy were more prone to leucopenia (P<0.01), while hypertension, the levels of white blood cell, neutrophil counting and serum creatinine before chemotherapy were protective factors for leucopenia (P<0.05 or<0.01). Multifactor Logistic regression analysis revealed that the level of serum creatinine before chemotherapy was an independent risk factor for leucopenia, OR = 0.950 (95% CI: 0.906- 0.996, P<0.05). The further analysis showed the lower the level of serum creatinine, the more severe the leucopenia would be (P = 0.04). Conclusions The level of serum creatinine before chemotherapy was an independent risk factor for colorectal cancer adjuvant chemotherapy induced leucopenia.
ABSTRACT
Objective To analyze the efficacy and safety of erlotinib associated conformal intensity modulated radiotherapy in treatment (IMRT) of locally advanced pancreatic carcinoma. Methods The clinical data of 23 patients with locally advanced pancreatic carcinoma were retrospectively analyzed. The patients′ therapeutic methods: erlotinib was taken continuously and orally at 100 mg/time, 1 time/d until disease progressed or serious adverse reactions happened; intensity modulated radiotherapy (IMRT) was used combined with erlotinib at 50.4 Gy, 1 time/d, 1.8 Gy/time, 5 times/week, total 28 times. Tumor response was evaluated at the end of radiotherapy after 4 weeks. Results In 23 patients, there was partial response in 10 cases, stable disease in 9 cases and progress disease in 4 cases. The objective response rate was 43.5%(10/23), and the median survival time was 11.3 months. Adverse reactions included fatigue, rash, bone marrow suppression, nausea and diarrhea. The adverse reactions were mostly tolerable with grade 1-2. Conclusions Erlotinib combined with IMRT is safe and effective in patients with locally advanced pancreatic carcinoma, which is worthy of further study.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the influence factors of salt-sensitive hypertension and to observe changes of blood pressures and urinary sodium and potassium excretion in response to acute oral saline loading among essential hypertensive patients in China.</p><p><b>METHODS</b>Essential hypertensive patients from Beijing Jinzhan second community were included in this study. Salt-sensitivity was determined via the improved Sullivan's acute oral saline loading and furosemide volume-depletion tests. Binary logistic regression analysis was applied to explore influence factors of salt-sensitive hypertension. Acute oral saline loading induced changes on blood pressures and urinary sodium and potassium excretion were observed.</p><p><b>RESULTS</b>Sixty-three salt-sensitive hypertensive patients were classified out of a total of 342(18.4%) essential hypertensive patients. Salt-sensitive patients were elder than the non-salt-sensitive patients (P < 0.05) . Binary logistic regression analysis showed that age (OR = 1.744, 95%CI:0.922-3.300, P > 0.05) , gender (OR = 0.728, 95%CI:0.374-1.415, P > 0.05) , total cholesterol level (OR = 1.168, 95%CI:0.882-1.547, P > 0.05) and 24-hour urinary sodium (OR = 0.998, 95%CI:0.995-1.002, P > 0.05) were not influencing factors of salt-sensitivity among essential hypertensive patients. Bivariate general linear models for repeated measures showed that there were significant statistical differences on blood pressures and urinary electrolytes concentrations between the beginning of trials, 2 hours after acute saline loading and 2 hours after furosemide volume-depletion(all P < 0.01). There was a greater blood pressures change in salt-sensitive patients than in non-salt-sensitive patients(all P < 0.01) while urinary electrolytes concentrations change was similar between two groups(all P > 0.05).</p><p><b>CONCLUSIONS</b>Age, gender, total cholesterol level and 24-hour urinary sodium are not influencing factors of salt-sensitivity among essential hypertensive patients in this study. Impaired pressure natriuresis during acute oral saline loading and furosemide volume-depletion tests is presented in salt-sensitive essential hypertensive patients.</p>
