OBJECTIVE: To investigate the safety and effectiveness of using the Taylor spatial frame (TSF) based on the Ilizarov tension-stress principle for treatment of post-burn foot and ankle deformities in adults. METHODS: A clinical data of 6 patients with post-burn foot and ankle deformities treated between April 2019 and November 2023 was retrospectively analyzed. There was 1 male and 5 females with an average age of 28.7 years (range, 20-49 years). There were 3 cases of simple ankle equinus, 2 cases of ankle equinus, midfoot rocker-bottom foot, and forefoot pronation, and 1 case of calcaneus foot and forefoot pronation. Preoperative American Orthopedic Foot and Ankle Society (AOFAS) score was 45.3±18.2, 12-Item Short-Form Health Survey (SF-12)-Physical Component Summary (PCS) score was 34.3±7.3 and Mental Component Summary (MCS) score was 50.4±8.8. Imaging examination showed tibial-calcaneal angle of (79.8±31.5)°, calcaneus-first metatarsal angle of (154.5±45.3)°, talus-first metatarsal angle of (-19.3±35.0)°. Except for 1 case with severe deformity that could not be measured, the remaining 5 cases had talus-second metatarsal angle of (40.6±16.4)°. The deformities were fixed with TSF after soft tissue release and osteotomy. Then, the residual deformities were gradually corrected according to software-calculated prescriptions. TSF was removed after maximum deformity correction and osteotomy healing. External fixation time, brace wearing time after removing the TSF, and pin tract infection occurrence were recorded. Infection severity was evaluated based on Checketts-Otterburns grading. Joint function was evaluated using AOFAS score and SF-12 PCS and MCS scores. Patient satisfaction was assessed using Likert score. Imaging follow-up measured relevant indicators to evaluate the degree of deformity correction. Deformity recurrence was observed during follow-up. RESULTS: The external fixation time was 103-268 days (mean, 193.5 days). The mild pin tract infections occurred during external fixation in all patients, which healed after pin tract care and oral antibiotics. No serious complication such as osteomyelitis, fractures, neurovascular injury, or skin necrosis occurred. After external fixation removal, 3 cases did not wear braces, while the remaining 3 cases wore braces continuously for 6 weeks, 8 weeks, and 3 years, respectively. All patients were followed up 13.9-70.0 months, with an average of 41.7 months. During follow-up, none of the 6 patients had recurrence of foot deformity. At 1 year after operation, the AOFAS score was 70.0±18.1, SF-12-PCS and MCS scores were 48.9±4.5 and 58.8±6.4, respectively, all showing significant improvement compared to preoperative values ( P<0.05). Imaging follow-up showed that all osteotomies healed, and all distraction cases achieved bony union at 6 months after stopping stretching. At 1 year after operation, tibial-calcaneal angle was (117.5±12.8)° and talus-first metatarsal angle was (-3.3±19.3)°, both showing significant improvement compared to preoperative values ( P<0.05). Calcaneus-first metatarsal angle was (132.0±14.4)°, which also improved compared to preoperative values but without significant difference ( P>0.05). Except for 1 case with severe deformity that could not be measured, the remaining 5 cases had talus-second metatarsal angle of (18.0±6.4)°. And there was no significant difference ( P>0.05) between pre-and post-operative data of 4 patients with complete data. At 1 year after operation, 1 patient was satisfied with effectiveness and 5 patients were very satisfied. CONCLUSION The TSF, by applying the Ilizarov tension-stress principle for gradual distraction and multi-planar adjustment, combined with soft tissue release and osteotomy, can effectively correct foot and ankle deformities after burns, especially equinus deformity with contracture of the posterior soft tissues of the lower leg. There are still limitations in treating cases with tight, adherent scars on the dorsum of the foot that require long-distance distraction. If necessary, a multidisciplinary approach combined with microsurgical techniques can be utilized.

Objective:To explore the predictors and reasons for restenosis in patients with Takayasu′s arteritis(TA) involved renal artery after plain old balloon angioplasty(POBA).Methods:The clinical data of 47 TA patients (47) with renal artery admitted to Xuanwu Hospital, Capital Medical University from January 2014 to December 2020 were analyzed, including 12 man and 35 female. The age ranged from 21 to 43 years old, with an average of (28.52±10.78) years old. All patient were diagnosed as TA and underwent POBA. The patients were divided into restenosis group ( n=18) and non-restenosis group ( n=29). The patients were followed up at 1, 3, and 6 months after surgery, and after 6 months, the patients were followed up every 6 months. All patients were followed up from 36 to 108 months.The basic clinical data of the two groups were compared, and the length of stent and residual stenosis were also compared. Measurement data were expressed as ( ± s), and t-test was used for comparison between groups. Counting data were expressed as the number of cases and percentage, and comparison between groups was analyzed using the chi-square test. Multivariate Logistic regression model was used to analyze the independent risk factors of restenosis after balloon dilation, and the OR value and 95% confidence interval were calculated. Logistic regression model was used to analyze the independent risk factors for restenosis after balloon dilation. Results:All patients received POBA and operation was successfully. Restenosis was found in 18 patients, and 29 patients remained normal during the follow-up. The primary patency rate was 61.7%. Multivariate Logistic regression analysis showed that HDL-C and lesion length were the influencing factors of restenosis after POBA in TA of renal artery. The serum HDL-C level was significantly lower and the lesion was significantly longer in restenosis group than in non-restenosis group ( P<0.05). The proportion of residual stenosis>20% was higher in restenosis group than in non-restenosis group ( P>0.05). Conclusion:Serum HDL-C level, lesion length may be may be independent influencing factors of restenosis after plain old balloon angioplasty in TA of the renal artery restenosis.

Objective:The study retrospectively analyzed the etiology, clinical manifestations, emergency treatment and etiological treatment of a large sample of cases with hypercalcemic crisis.Methods:The clincial data of patients with hypercalcaemia cirisis who were administered in First Medical Center of Chinese PLA General Hospital from January 2009 to July 2022 were analyzed, inculding the general data, clinical manifestations, etiology, photographic examination, emergency treatment, etiological treatment, serological examination before and after treatment, pathological immunohistochemical findings and prognosis.Results:A total of 143 hypercalcaemia crisis patients(84 males and 59 females) with a mean age of 53.51±16.60 were enrolled. The most common disease was hyperparathyroidism(62/143), followed by solid malignancy(57/143) and multiple myeloma(12/143). Patients presented with digestive system symptoms at 76.91%, followed by neurological symptoms at 63.60%, urinary system symptoms at 58.76%, musculoskeletal symptoms at 55.23%, and cardiovascular system symptoms at 32.91%. After emergency calcium-lowering treatment, the remission rate of hypercalcemic crisis in 143 patients was 100%(143/143), and after etiological treatment, the remission rate of hypercalcemia was 85.31%(122/143).Conclusion:Early identification, emergency treatment and etiology treatment of hypercalcaemia crisis are essential. Effective treament with comprehensive calcium reduction can quickly relieve clinical symptoms and create opportunities for treatment for the cause. Targeted etiological interventions can lead to the correction or long-term remission of hypercalcemia.

Objective:To observe any effect of percutaneous tibial nerve stimulation (PTNS) combined with electro-acupuncture on detrusor overactivity after a spinal cord injury.Methods:Forty spinal cord injury survivors with neurogenic detrusor overactivity were randomly assigned to a control group or an observation group, each of 20. Both groups received routine bladder training and electro-acupuncture modulating 3 sacral spinal nerves. The observation group also received 20 minutes of bilateral PTNS five times a week for 8 weeks. The frequency was 10Hz with a pulse width of 200μs. Before and after the treatment, both groups′ urination frequency, incontinence and average daily urine volume were assessed using a urodynamics analyzer, bladder diaries and an incontinence quality of life questionnaire (I-QOL).Results:After treatment, the average involuntary detrusor contraction volume (IDCV), maximum detrusor pressure at filling time (P det·max), bladder compliance (BC), residual volume and the TL value of the electromyogram of the urethral sphincter (LgTLR) had all improved significantly in both groups. The 1st IDCV, BC and LgTLR of the observation group were then significantly better than in the control group, on average, with the average P det·max and residual volume significantly lower than in the control group. The average daily single urine output and I-QOL score of both groups had increased significantly, while the average daily urination frequency and frequency of urinary incontinence had decreased significantly. Both were again significantly better in the observation group. Conclusion:Combining percutaneous electrical stimulation of the tibial nerves with electro-acupuncture can effectively inhibit detrusor overactivity after a spinal cord injury, reducing urinary incontinence.

Objective:To seek a correlation between short-chain fatty acids (SCFAs) and skill in the activities of daily living (ADL) after an ischemic stroke.Methods:Ninety ischemic stroke survivors were assessed using the Barthel Index (BI). Fecal samples were collected and analyzed for the concentration of acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, and isovaleric acid using gas chromatography. Spearman correlation analysis was conducted to identify SCFAs that correlated with the total BI score. Linear regressions were evaluated to explore the correlation between the total BI score and SCFAs.Results:The concentrations of propionic and butyric acids in the feces were found to correlate significantly with the total BI scores. Data including propionic acid and butyric acid levels, age, gender, body mass index, disease duration, any history of hypertension or diabetes, and other SCFAs were included in the regression models. Propionic and butyric acid levels were found to be potentially useful predictors of total BI scores.Conclusions:The concentration of propionic and butyric acids in the feces after an ischemic stroke can predict the survivor′s total BI score. Those concentrations could therefore be useful for predicting ADL ability.
