Advances in non-operative treatment of advanced hypopharyngeal squamous cell carcinoma / 国际肿瘤学杂志

Hypopharyngeal squamous cell carcinoma has a high degree of malignancy, hidden location, atypical early symptoms, most patients have reached advanced stage at the time of treatment. Surgical treatment will cause patients to lose laryngeal function and poor postoperative quality of life. The combined application of non-operative therapies such as radiotherapy and chemotherapy can improve the larynx preservation rate of patients and obtain a survival rate similar to that of surgical treatment. Targeted therapy has achieved better results in the treatment of hypopharyngeal squamous cell carcinoma, and immunotherapy has also made great progress in the treatment of head and neck squamous cell carcinoma, which brings new hope for patients with hypopharyngeal squamous cell carcinoma.

Semi-occlusive dressing as non-operative treatment vs. operative treatment for fingertip amputations: A retrospective cohort study

INTRODUCTION@#Treatment of fingertip amputations have demonstrated good outcomes with both surgical and nonsurgical management.@*OBJECTIVE@#The objective of this study was to compare non-operative treatment with semi-occlusive dressing with any surgical treatment for fingertip amputations in adult fingers, Allen types I-III in a retrospective cohort review.@*METHODS@#A retrospective chart review was done on adult patients with fingertip amputations Allen types I-III from January 1, 2018 to December 31, 2020. Patients included in the studies were distributed into two treatment groups: non-operative and operative groups. Outcomes to be measured were time to full healing, range of motion, nail deformities, Tinel’s sign, and discoloration of the reconstructed fingertip.@*RESULTS@#A total of 38 patients with 40 digits were included (19 patients with 20 digits for each treatment group). The results showed a larger defect for the operative group (3 cm2 vs 2.1 cm2), with shorter time to healing (1.4 months vs 2.2 months). There were more complications in the operative group like the Tinel’s sign, nail deformity and discoloration, as well as joint contractures. Range of motion was better for patients treated non-operatively.@*CONCLUSION@#Treatment with semi-occlusive dressing showed similar results in terms of wound healing but takes a longer time and less complications compared to operative treatment.

Analysis of risk factors related to death within 1 year after non-operative treatment of hip fractures in the elderly / 中华老年医学杂志

Objective:To analyze the risk factors for death within one year after non-operative treatment of hip fractures in the elderly.Methods:Clinical data of 83 elderly patients with hip fractures treated non-operatively from March 2012 to March 2017 who had met the criteria of inclusion and exclusion were included.They were divided into the death group and the survival group according to whether they had died within one year after non-operative treatment.Univariate and multivariate regression analysis were used to screen risk factors for death within one year after non-operative treatment.Results:Of the 83 patients, 26(31.3%)died within one year, including 10(38.5%)from pulmonary infections and 6(23.1%)from acute myocardial infarction.Univariate analysis showed that age, gender, walking ability before a fracture, number of comorbidities, coronary heart disease and COPD each had a significant impact on the death of patients within one year after receiving non-operative treatment( P<0.05). Multivariate Logistic regression analysis showed that age(≥76 years old)( OR=12.704, P=0.001), COPD( OR=5.870, P=0.042)and coronary heart disease( OR=7.451, P=0.007)were independent risk factors for death within one year after non-operative treatment. Conclusions:The mortality is as high as 31.3% in elderly patients with hip fractures within one year after non-operative treatment.The main cause of death is pulmonary infections.Age(≥76 years old), COPD and coronary heart disease are independent risk factors for death within one year after non-operative treatment.

RESUMEN Se presenta el caso clínico de un paciente con traumatismo abdominal por herida de arma de fuego (HAF). En otra institución se realizó cirugía de exclusión pilórica y hepatorrafia por lesión hepatoduo denal. Fue derivado a nuestra institución a las 12 horas posoperatorias. Intercurre en el posoperatorio con neumonía grave por COVID-19 y complicaciones de su cirugía ini cial. La presentación severa de la enfermedad nos inclina por el manejo no operatorio. La utilización de drenajes percutáneos permitió el manejo de colecciones evitando una cirugía mayor inicial. La recuperación pulmonar facilitó la cirugía definitiva. La neumonía severa por COVID-19 en un paciente con lesión duodenal grave por HAF condiciona la toma de decisiones.

ABSTRACT We report the case of a patient with an abdominal gunshot trauma with liver and duodenal injury who underwent pyloric exclusion and liver repair in another institution. The patient was transferred to our institution 12 hours after surgery. During hospitalization, severe pneumonia due to COVID-19 and complications of the initial surgery developed. Non-surgical management was decided due to the severity of the disease. Percutaneous drainage allowed for the management of the collections avoiding a major initial surgery. Once he recovered from the pneumonia, the definite surgery was performed. Severe COVID-19 pneumonia in a patient with serious duodenal shotgun injury is a determining factor for decision-making of treatment options.

Quality of life of carpal tunnel syndrome with non operative treatment: cohort study

Background: Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy entrapment and it interferes with the quality of life. Treatment for CTS can be divided into operative and non-operative treatment. Our objective was to compare the quality of life and pain intensity in a patient with CTS after oral treatment and local corticosteroid injection (LCI).Methods: A prospective cohort study was conducted in 18-65 years patients with CTS. Primary outcome was to compare the quality of life post oral treatment (NSAIDs, oral steroids, gabapentin) and LCI using the Short Form-36 questionnaire. Secondary output was to compare pain intensity using Numeric Rating Scale (NRS). Mann-Whitney and independent t-test were used to assess the comparison between the treatment.Results: Sixty CTS patients were included in this study, with 32 patients (53.33%) assigned to LCI. After observation one month, statistical analysis showed that LCI improved the quality of life better than oral in physical function and bodily pain components (p = 0.036 and p = 0.047). Injection treatment decreased pain intensity more than oral not statistically significant after 14 days (p=0.087), but was significant after one month (p=0.002).Conclusions: Local corticosteroid injection improved quality of life and decreased pain intensity better than oral treatment after one month.

Ultrasound-guided percutaneous microwave ablation assisted by a three-dimensional visualization preoperative treatment planning system for larger adrenal metastasis (D ≥ 4 cm): Preliminary results

Objective: The objective of this study is to assess the clinical effect and safety of ultrasound-guided percutaneous microwave ablation (US-PMWA) assisted by three-dimensional (3D) visualization operative treatment planning system in larger adrenal metastasis (LAM) (D ≥ 4 cm). Materials and Methods: From Dec 2011 to Dec 2017, 12 consecutive LAM patients with pathologically proven with a mean diameter of 5.2±1.3cm (range 4.1-7.6) were treated. Artificial ascites and thermal monitoring system as ancillary technique were used. The patients were followed up with imagings and complications were recorded. Results: The median follow-up period was 31 months (ranged 6–52 m). All LAM achieved completely ablation according to the 3D planning preoperation. Complete ablation was achieved in 10 (10/12, 83.3%) patients by one session and 2 patients (2/12, 16.7%) by two sessions. Recurrence was detected at the treated site in 3 patients (3/12, 25.0%) at 5, 9, and 13 months after ablation and received another ablation. Progression of metastasis disease at extra-adrenal sites occurred in 9 patients (9/12, 75%). Seven (7/12, 58.3%) patients died during the follow-up period. Therefore, the 1-, 2-, and 3-year local tumor control rates were 83.3%, 75.0%, and 75.0%, and 1-, 2-, 3- and 4-year overall survival rates were 91.7%, 75.0%, 50.0%, and 41.7%, respectively. No severe complications related to ablation occurred, except 3 (3/12, 25%) patients developed hypertension during ablation. Conclusions: US-PMWA assisted by 3D visualization preoperative treatment planning system maybe a safe and efficient therapy for LAM, which could promote ablation precision, improve the clinical outcomes

Association between the time of neutrophils to the lowest and prognosis of patients with esophageal squamous cell carcinoma treated with non-operative therapy / 中华肿瘤杂志

Objective@#To investigate the association between the time of neutrophils to the lowest and prognosis of patients with esophageal squamous cell carcinoma (ESCC) treated with non-operative therapy.@*Methods@#The clinical data of 325 non-operative treated ESCC patients were collected in this study. The X-title software was applied to establish optimal threshold of neutrophil reduction to the lowest value. According to the optimal threshold, the patients were divided into early group (115 cases) and late group (210 cases). The clinical features and survival time of the two groups were compared, and the factors of prognosis were analyzed by Cox regression model with univariate and multivariate analysis.@*Results@#The X-title software demonstrated the optimal cutoff values for the time of neutrophils to the lowest was 39 days. The median overall survival time was 21.0 months in the early group which was significantly higher than that in the late group (16.0 months). Multivariate Cox regression analysis showed that the treatment methods and the time of neutrophils to the lowest were independent factors for overall survival of patients with ESCC treated by non-surgical therapy. Compared with radiotherapy alone, concurrent chemoradiation could benefit the survival (HR=0.64, P=0.026). The prognosis of patients in the late group of neutrophils to the lowest (HR=1.38, P=0.038) was poor compared with the early group. Furthermore, stratified by treatment methods, the overall survival of two groups showed statistically significant difference only in patients received concurrent chemoradiation. The mortality risk in the late group was higher than that in the early group (HR=3.53, P=0.010).@*Conclusion@#The time of neutrophils to the lowest is an independent prognosis factor for non-operative treated ESCC patients. The prognosis of patients in the early group is better than that in the late group.

Application of multi-mode combined analgesia in the early stage of non-operative treatment of traumatic rib fractures in adults / 中华胸心血管外科杂志

Objective@#To evaluate the analgesic effect of a new combined analgesic mode in the early stage of non-operative treatment of adult traumatic rib fractures.@*Methods@#A total of 93 patients with rib fractures who did not receive surgical treatment from January 2014 to January 2018 were prospectively included, and randomly divided into the traditional analgesia group, subcutaneous analgesia group and combined analgesia group(31 cases each). There were 56 males and 37 females totally with a median age of(47.3±13.2)years. All patients have moderate to severe pain with VAS scores greater than 5. Traditional analgesia group: lornoxicam 8 mg intravenous injection twice daily. Subcutaneous analgesia group: only subcutaneous self-controlled analgesia pump was used for treatment. Combined analgesia group: on the basis of the traditional analgesia group, subcutaneous self-controlled analgesia pump was added for treatment, and the dosage of the pump drug was the same as that of subcutaneous analgesia group. The VAS scores at tranquillization and cough were compared before analgesia treatment(T1), 24 h(T2), 48 h(T3) and 72 h(T4) after analgesic treatment in each group during bed brake within 3 days after injury. The VAS scores after 78 hours of analgesic treatment during ambulation were compared. When sudden pain with VAS score greater than 7 occurred within 72 hours of bed staying treatment in each group, the average daily use times of bucinnazine hydrochloride 100mg remedial analgesia were compared. The number of adverse reactions such as nausea and pneumonia in each group was compared.@*Results@#The VAS scores of resting pain and cough pain at the observation time point(T2-T4) in the combined analgesia group were better than those in the subcutaneous analgesia group and the traditional analgesia group, showing a significant difference(P<0.05). When getting out of bed, there were significant differences in pain scores among the three groups, and the pain score of the combined analgesia group was the lowest. There was a significant difference among the three groups in the number of daily additions of bucinnazine hydrochloride during remedial analgesia(P<0.05), the combined analgesia group was the least. Between the two groups of patients using analgesic pump, the number of self-compressions in the combined analgesia group was lower than that in the subcutaneous analgesia group(P<0.05). The incidence of pneumonia in the combined analgesia group was lower than that in the other two groups and the incidence of other adverse reactions such as nausea was lower than that in the simple analgesia group.@*Conclusion@#In the early stage of non-operative treatment of traumatic rib fractures in adults, the multi-mode analgesic effect of traditional intravenous intermittent administration combined with subcutaneous continuous administration is superior to the single analgesic mode of traditional intravenous or subcutaneous administration with no obvious adverse reactions.

Treatment Options of Osteoporotic Vertebral Compression Fractures

This paper reviews previous studies on the treatment of osteoporotic vertebral compression fractures in elderly patients to determine what factors should be considered for successful treatment. In osteoporotic vertebral compression fractures, the primary treatment is conservative treatments. Other treatments include osteoporosis treatment, pain control, orthosis, and physical therapy. Recently, percutaneous catheterization or balloon plasty is performed for rapid pain recovery and early ambulation. Percutaneous catheterization or balloon posterior plasty is effective in reducing pain and improving the activity ability. Surgical treatment should be considered in cases of nonunion or osteonecrosis, dent, deformation, and spinal cord compression after conservative treatment has failed. In surgical treatment, posterior spinal fixation and vertebroplasty are more advantageous in terms of the amount of bleeding, operation time compared to the anterior approach, but the most appropriate method should be selected through the patient's condition and understanding of each surgical method.

A Systematic Review and Meta-analysis of Randomized Controlled Trials Comparing Surgical versus Conservative Treatments for Acute Undisplaced or Minimally-Displaced Scaphoid Fractures

BACKGROUND: Surgical and conservative methods have been reported by various studies for high rates of fracture union and subsequent regain of function among patients with undisplaced or minimally-displaced scaphoid fractures. Hence, this study aims to analyze the best available evidence to comprehend the relative benefits and risks of these therapeutic options. METHODS: A systematic search of the literature from different databases and search engines was performed with strict eligibility criteria to obtain the highest quality of evidence. All randomized controlled trials delineating the outcomes of surgical versus conservative treatments for acute undisplaced or minimally-displaced scaphoid fractures were included and then evaluated using scoring tools: Cochrane risk of bias tool and PEDro scale. Data were pooled using random-effects models with standard mean differences for continuous outcomes and risk ratios for dichotomous variables. RESULTS: The search yielded 339 potentially related articles, further trimmed down to eight studies based on the eligibility criteria. The meta-analysis revealed that surgical treatment resulted in significantly better functional outcomes than conservative treatment. Furthermore, surgery resulted in the prevention of delayed union of fractures and reduction of time needed to return to work. CONCLUSIONS: While four studies reported advantages of surgical treatment, evidence was insufficient to provide a definitive conclusion that surgery is a better option. Due to the significant limitations with respect to certain variables, the superiority of one method to the other could not be established.

Comparison of the Results between Conservative and Operative Treatments for Pyogenic Spondylitis / 대한정형외과학회잡지

PURPOSE: With advancements in antibiotics, the ability to treat pyogenic spondylitis is increasing. This study aimed to compare and analyze the outcomes between conservative and operative treatments. MATERIALS AND METHODS: Sixty patients (28 males and 32 females) with pyogenic spondylitis, who were hospitalized and treated between February 2008 and June 2016, were enrolled. Patients were divided according to the following: type of treatment – conservative or operative treatment, method of surgery, radiographic parameters, location of the affected spine. Clinical parameters as durations of hospital stay, intravenous antibiotics use, normalization in laboratory findings, and residual symptoms were analyzed. For statistical evaluation, independent-sample t-test, Mann-Whitney U-test, Pearson's chi-square test, one-way ANOVA, and Spearman correlation analysis were performed retrospectively. RESULTS: There was no significant difference in the duration of hospital stay, intravenous antibiotics use, normalization in laboratory findings, and residual symptoms between the conservative and operative treatment groups. CONCLUSION: In treating pyogenic spondylitis, conservative treatment can be considered as the first choice, and operative treatment can be chosen in refractory cases.

Operative Treatment for Extensor Carpi Ulnaris Tendon Dislocation / 대한정형외과학회잡지

PURPOSE: Extensor carpi ulnaris (ECU) subluxation has a low incidence rate, to date, there has only been a few studies evaluating the operative treatment for type of injury. The purpose of this study was to retrospectively analyze 11 patients with ECU subluxation who underwent operative treatment. MATERIALS AND METHODS: Between March 2005 and February 2015, 11 patients received operative treatment. Magnetic resonance imaging and dynamic ultrasound were used to make the diagnosis. ECU subluxation patterns were classified by the Inoue's classification system. There were two cases of type A, one case of type B, five cases of type C, and three cases unfit for Inoue's classification. We also found two cases of radial subluxation and one case of ulnar locked subluxation. In type A and B cases, ECU tendons were relocated then sheaths repair was performed, and the extensor retinaculum reconstruction was performed. In type C cases, the fibro-osseous sheaths were fixed. In the three unclassified cases, extensor retinaculum reconstruction was performed. In all cases, fibro-osseous sheaths were fixed using the anchor suture technique. We compared the clinical results based on the following: motion range of the wrist joint; grip strength; visual analogue scale (VAS) score; quick disabilities of the arm, shoulder and hand (Q-DASH) score; and Mayo wrist score. RESULTS: The median age of patients at the time of the operation was 32 years, and the average follow-up period was 11.2 months. There were five cases of triangular fibrocartilage complex tear, two cases of distal radioulnar joint instability, three cases of ECU split tear as accompanying injury. There were significant differences in the clinical results. The average motion range of the wrist increased compared with the preoperative value (84.7% to 92.4% compared to contralateral normal side). The postoperative VAS score, Q-DASH score and Mayo wrist score showed better results compared with the respective preoperative values (6.0 to 1.1, 40.9 to 12.4, 75.9 to 86.4). CONCLUSION: ECU subluxation is a rare occurrence. Dynamic ultrasound is useful in diagnosing ECU tendon subluxation. Satisfactory results can be obtained with the use of a proper technique, which depends on the type of subluxation.

Clinical study on pleth variability index for monitoring volume responsiveness in patients undergoing intestinal tract surgery / 重庆医学

Objective To evaluate the ability of pleth variability index(PVI) for predicting volume responsiveness after general anesthesia induction intubation in the patients undergoing intestinal tract surgery with the velocity-time integral(VTI) of left ventricular outflow tract blood monitored by transthoracic echocardiography as the standard.Methods Twenty-five patients undergoing intestinal tract surgery were selected.After general anesthesia induction,7 mL/kg colloidal solution was infused before operation beginning,if the VTI increased percentage(△VTI％)≥10 ％,200 mL colloidal solution was infused by 50mL syringe until △VTI％＜10％;the hemodynamic indicators of MAP,CVP,HR,PI VTI and PVI were recorded before and after infusion solution.Results The PVI basic value in the patients with response was significantly higher than that in the patients without response(P＜0.05);the Pearson correlation analysis found that there was a significant linear correlation between PVI basic value and △VTI％ before infusion solution(P＜0.05);the optimal diagnostic threshold value of PVI was 13.51,its sensitivity for monitoring the volume responsiveness was 69.25％ and specificity was 70.00％.The area under the receiver operating characteristic(ROC) curve(AUC) was 0.75(95％ CI:0.63-0.88,P＜0.01).Conclusion PVI can predict the volume responsiveness in the patients undergoing intestinal tract surgery.The PVI value ＞13.51 indicates that the patient may be in hypovolemia status and needs the volume therapy.
