Tislelizumab bridging to umbilical cord blood transplantation therapy for relapsed/refractory acute myeloid leukemia: report of 1 case and review of literature / 白血病·淋巴瘤

Objective:To explore the efficacy of tislelizumab combined with umbilical cord blood transplantation (UCBT) in relapsed/refractory acute myeloid leukemia (R/R AML) patients.Methods:The diagnosis and treatment of 1 patient with R/R AML who received tislelizumab bridging to UCBT after the failure of re-induction treatment in the First Affiliated Hospital of Soochow University in November 2021 was retrospectively analyzed.Results:The 59-year-old male patient with R/R AML achieved a complete remission after initial induction chemotherapy regimen of decitabine and venetoclax, and then additional consolidation therapy regimens of decitabine and middle-dose cytarabine, middle-dose cytarabine and idarubicin were performed. The patient relapsed 16 months later and failed to achieve a second remission after re-induction therapy regimens of cladribine, azacitidine, venetoclax combined with chemotherapy, and homoharringtonine, cytarabine combined with granulocyte colony-stimulating factor. Tislelizumab significantly reduced tumor burden and the patient achieved the complete remission after bridging to UCBT. After transplantation, the patient was given maintenance treatment with azacitidine and he had sustained remission without severe transplant-related complications during 9-month follow-up.Conclusions:The use of tislelizumab bridging UCBT can be a potential therapeutic strategy for R/R AML patients.

Application of three-dimensional printed endoprosthesis for reconstruction after metaphysis-involved intercalary tumor resection / 中华骨科杂志

Objective:To describe the design, manufacture and use of three-dimensional (3D)-printed endoprosthesis for reconstruction after metaphysis-involved intercalary tumor resection and to evaluate its outcome.Methods:Forty-three patients who received metaphysis-involved intercalary tumor resection followed by 3D-printed endoprosthetic reconstruction in Musculoskeletal Tumor Center, Peking University People's Hospital between January 2018 and December 2021 were retrospectively reviewed. There were 25 males and 18 males with an average age of 20.1±15.2 years (range, 4-58 years). The pathological diagnosis included 24 cases of osteosarcomas, 6 cases of Ewing sarcomas, 5 cases of chondrosarcomas, 2 cases of pleomorphic undifferentiated sarcomas, 3 cases of soft-tissue sarcomas (liposarcoma, synovial sarcoma, malignant peripheral nerve sheath tumor for each) and 3 others (adamantinoma, recurrent aneurysmal bone cyst and recurrent osteofibrous dysplasia for each). The tumors located at femur in 25 patients (58%), including 14 lesions involving distal femoral metaphysis and 11 lesions involving both proximal and distal metaphysis; the tumors located at tibia in 11 patients (26%), including 4 lesions involving distal tibial metaphysis, 5 lesions involving proximal tibial metaphysis and 2 lesions involving both proximal and distal tibial metaphysis; the tumors located at humerus in 7 patients (16%), including 1 lesion involving distal humeral metaphysis, 3 lesions involving proximal humeral metaphysis and 3 lesions involving both proximal and distal humeral metaphysis. The endoprosthesis was designed in a semi-modular fashion and consisted of three parts: a diaphysis-fixing component, a semi-modular lap joint component, and a custom-made 3D-printed metaphysis-fixing component which was designed as two types with 3D-printed porous bone-contacting surfaces according to the osteotomy plane (Type I on meta-diaphyseal region, Type II on meta-epiphyseal region). The functional outcome was assessed using Musculoskeletal Tumor Society (MSTS) 93 system.Results:All surgeries were accomplished sucessfully. The median resection length and the distance from osteotomy plane to adjacent joint was 16.0 (13.0, 22.0) cm and 4.5 (3.5, 6.0) cm, respectively. 59 metaphysis-fixing components were installed in 43 patients. Type I components were used in single and dual ends of endoprosthesis in 12 and 6 cases respectively. Type II components were used in single and dual ends in 15 and 5 cases respectively. Hybrid endoprosthesis with Type I and II components were used in 5 cases. The mean follow-up time was 26.0 (17, 37) months (range, 12-54 months). The mean MSTS 93 score was 29.0 (28.0, 30.0) points (range, 21-30 points). Implant failures were found in 5 patients, including 2 cases of aseptic loosening (loosening was observed in the cementing diaphysis-fixing stems while no evidence of loosening in metaphysis-fixing components) and 3 cases of local tumor progression. The 2-year implant survival rate was 90.3% (95% CI: 0.81, 0.99). Conclusion:Using 3D-printed intercalary endoprosthesis for reconstruction after intercalary resection of metaphysis-involved bone tumor shows satisfactory functional outcome and implant survival. Moreover, by assembling endoprosthetic components according to the different osteotomy plane, the semi-modularized endoprosthesis also provids a comprehensive and individualized reconstruction for patients with metaphysis-involved intercalary tumor.

Progress on management of periviable extremely premature infants / 中华围产医学杂志

Periviable extremely preterm infant (PEPI) refers to preterm infants born on the border of viability, mainly those with gestational age less than 24 weeks or birth weight less than 500 g. PEPI has increased in the past decades, and about half of the survivors live without severe neurodevelopmental impairment. The management of PEPI remains one of the most complex fields in perinatal-neonatal medicine. Active interventions can reduce the risk of morbidity and mortality in PEPI during early life and short-term follow-up after discharge without increasing the risk of neurodevelopmental impairment. Clinical decision-making about PEPI should not be restricted to population-based prenatal data but should mainly be based on postnatal individual characteristics and conditions. Parents should make an informed choice after detailed consultation with their physician. When the prognosis is uncertain, resuscitation and intensive care could be given and reassessed subsequently. Current interventions or treatments of PEPI refer to strategies for infants born at 24-27 gestational weeks, which need to be refined in practice.

Efficacy observation of lenalidomide in treatment of relapsed/refractory diffuse large B-cell lymphoma / 白血病·淋巴瘤

Objective:To explore the clinical efficacy of lenalidomide combined with second-line immunochemotherapy as a salvage regimen in the treatment of relapsed/refractory diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of 37 relapsed/refractory DLBCL patients receiving lenalidomide combined with second-line immunochemotherapy as a salvage regimen who had recurrence after autologous hematopoietic stem cell transplantation or who were not eligible for transplantation or had no intention to transplant between January 2016 and December 2020 in the First Affiliated Hospital of University of Science and Technology of China were retrospectively analyzed. Among 37 patients, 6 cases with primary central nervous system (CNS) lymphoma and 3 cases with secondary CNS lymphoma. The short-term efficacy after treatment was evaluated. Kaplan-Meier method was used to analyze the overall survival (OS) and progression-free survival (PFS), and log-rank test was used for subgroup comparison.Results:The median follow-up time of 37 patients was 20.4 months (2.7-37.0 months). At the end of treatment, the overall response rate (ORR) of all patients was 64.9% (24/37), the complete response (CR) rate was 45.9% (17/37), and the median duration of response (DOR) of 24 patients who responded to treatment was 17.7 months (3.6-33.6 months). The median PFS time of all patients was 11.2 months, and the 1-year PFS rate was 48.6% (95% CI 32.5%-64.7%). The median OS time of all patients was not reached, and the 1-year OS was 67.6% (95% CI 52.5%-82.7%). Among 24 responding patients, 17 cases who received lenalidomide maintenance therapy after remission tended to have a better response compared with 7 cases who did not receive lenalidomide maintenance therapy after remission, although there was no significant difference in OS and PFS between both groups (both P > 0.05). Additionally, neutropenia was the most common adverse reaction with an incidence of 81.1% (30/37). Conclusions:Lenalidomide combined with the second-line immunochemotherapy may be an effective salvage therapy for patients with relapsed/refractory DLBCL, especially for patients with CNS involvement. The patients achieving remission after salvage therapy continue to receive lenalidomide maintenance therapy and could have a better prognosis.

Clinical and radiographic outcomes following salvage intervention for ureteropelvic junction obstruction

ABSTRACT Purpose: We aimed to assess failure rates of salvage interventions and changes in split kidney function (SKF) following failed primary repair of ureteropelvic junction obstruction (UPJO). Materials and Methods: A retrospective review of adult patients at an academic medical center who underwent salvage intervention following primary treatment for UPJO was performed. Symptomatic failure was defined as significant flank pain. Radiographic failure was defined as no improvement in drainage or a decrease in SKF by ≥7%. Overall failure, the primary outcome, was defined as symptomatic failure, radiographic failure, or both. Results: Between 2008-2017, 34 patients (median age 38 years, 50% men) met study criteria. UPJO management was primary pyeloplasty/secondary endopyelotomy for 21/34 (62%), primary pyeloplasty/secondary pyeloplasty for 6/34 (18%), and primary endopyelotomy/secondary pyeloplasty for 7/34 (21%). Median follow-up was 3.3 years following secondary intervention. Patients undergoing primary pyeloplasty/secondary endopyelotomy had significantly higher overall failure than those undergoing primary pyeloplasty/secondary pyeloplasty (16/21 [76%] vs. 1/6 [17%], p=0.015). Among patients undergoing secondary endopyelotomy, presence of a stricture on retrograde pyelogram, stricture length, and SKF were not associated with symptomatic, radiographic, or overall failure. Serial renography was performed for 28/34 (82%) patients and 2/28 (7%) had a significant decline in SKF. Conclusions: Following failed primary pyeloplasty, secondary endopyelotomy had a greater overall failure rate than secondary pyeloplasty. No radiographic features assessed were associated with secondary endopyelotomy failure. Secondary intervention overall failure rates were higher than reported in the literature. Unique to this study, serial renography demonstrated that significant functional loss was overall infrequent.

Salvage allogeneic hematopoietic stem cell transplantation under venetoclax bridging myeloablative preconditioning regimen for an acute myeloid leukemia patient with primary induction therapy failure / 白血病·淋巴瘤

Objective:To explore the application of venetoclax in transplantation of patients with refractory acute myeloid leukemia (AML).Methods:The diagnosis and treatment process of a patient with refractory AML who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) under venetoclax and hypomethylating agents bridging myeloablative preconditioning regimen after induction therapy failure in the First Affiliated Hospital of Soochow University in March 2020 were retrospectively analyzed.Results:The patient was a 28-year-old female who was diagnosed with refractory AML. The patient was initially given induction chemotherapy with IA (idarubicin+cytarabine) (3+7) regimen, but the disease did not relieve, then the induction chemotherapy with CLAG (cladribine+cytarabine+granulocyte colony stimulating factor) regimen was given, but the disease still did not relieve. After chemotherapy with venetoclax and hypomethylating agents bridging myeloablative preconditioning regimen, salvage haploid allo-HSCT was performed. Re-examination of bone marrow showed remission, and implantation was successful. The patient was followed up for 100 days and had sustained remission, and no transplantation complications occurred.Conclusion:For refractory AML patients who have failed primary induction therapy, the use of venetoclax and hypomethylating agents bridging myeloablative preconditioning regimen can be used as a preferred solution for salvage allo-HSCT.

Prevalence of central venous catheter salvage in newborn with staphylococcal bloodstream infection / Prevalencia del rescate del catéter venoso central en recién nacidos con infección del torrente sanguíneo estafilocócica / Prevalência de salvamento de cateter venoso central em recém-nascidos com infecção de corrente sanguínea estafilocócica

ABSTRACT Objectives: to establish the prevalence of salvage of central venous catheters in newborns with bloodstream infection caused by coagulase-negative staphylococci. Methods: retrospective cross-sectional study with 136 newborns admitted to the Neonatal Intensive Care Unit between 2011 and 2017. The total of 143 infection events undergoing antibiotic therapy were evaluated. Results: among the 143 infection events, 39 catheters in which antibiotic therapy was used were saved and in 69 cases, the device was removed. Positive central blood culture and single lumen catheter were factors associated with salvage failure. The probability of salvage decreased with infections diagnosed from 15 days of using the catheter. Negative blood culture raised the chance of salvage by fourfold. Conclusions: the use of antibiotic therapy in the treatment of infections resulted in a low prevalence of salvage of the central venous catheter. The probability of salvage was associated with variables of the device.

RESUMEN Objetivos: establecer la prevalencia de rescate de catéteres venosos centrales en recién nacidos con infección del torrente sanguíneo causada por estafilococos coagulasa negativos. Métodos: estudio transversal retrospectivo con 136 recién nacidos ingresados en la Unidad de Cuidados Intensivos Neonatales, entre 2011 y 2017. Se evaluaron 143 eventos de infección sometidos a terapia antibiótica. Resultados: de los 143 eventos de infección, se rescataron 39 catéteres en los que se utilizó antibioticoterapia y en 69 casos se retiró el dispositivo. El hemocultivo central positivo y el catéter de un lumen fueron factores asociados con el fracaso del rescate. La probabilidad de rescate disminuyó con las infecciones diagnosticadas a partir de los 15 días de uso del catéter. Los hemocultivos negativos multiplicaron por cuatro la posibilidad de recuperación. Conclusiones: el uso de terapia antibiótica en el tratamiento de infecciones resultó en una baja prevalencia de rescate del catéter venoso central. La probabilidad de rescate se asoció con las variables del dispositivo.

Performance and Impact of Prostate Specific Membrane Antigen-Based Diagnostics in the Management of Men with Biochemical Recurrence of Prostate Cancer and its Role in Salvage Lymph Node Dissection

To compare salvage liver transplantation with othotopic liver transplantation for patients with hepatocellular carcinoma: a Meta-analysis / 中华肝胆外科杂志

Objective To compare salvage liver transplantation (SLT) with othotopic liver transplantation (OLT) in treatment of hepatocellular carcinoma.Methods A systematic literature search of PubMed,Embase,Cochrane Library,CBM,CNKI and Wanfang Med Online was performed from their dates of establishment to October 2017.The results were screened,data extracted and then analyzed with Stata 14.Results 23 studies with 4 161 patients were selected,including 579 patients in the SLT group and 3 582 patients in the OLT group.Compared with OLT,SLT was associated with a longer operative time (SMD =0.56,95％CI:0.29～0.83),higher intraoperative blood loss (SMD=1.56,95％CI:0.63～2.49),an increased risk of postoperative bleeding (OR =1.84,95％CI:1.08 ～ 3.14),a poorer overal survival rate (HR =1.29;95％CI:1.11～1.49) and disease free survival rate (HR=1.88;95％CI:1.26～2.81).The differences were all significant (all P＜0.05).The biliary complications (OR=1.25;95％CI:0.79～1.98),vascular complications (OR=1.41;95％CI:0.69～2.89),sepsis (OR=1.10;95％CI:0.60～ 1.99),acute rejection (OR =1.25;95％ CI:0.69 ～ 2.28) and perioperative mortality (OR =1.60;95 ％ CI:0.94 ～ 2.70) rates were not significantly different (all P＞0.05).Conclusions OLT is a better treatment strategy for patients with transplantable hepatocellular carcinoma (HCC) compared with SLT.However,severe organ limitation,and feasibility and safety of surgery make SLT a better option for patients with HCC recurrence after liver resection.

Clinical study of salvage strategy for patients with locally recurrent esophageal cancer after definitive radiochemotherapy / 中华放射肿瘤学杂志

Objective@#To investigate the salvage strategy and efficacy for patients with locally recurrent esophageal squamous cell carcinoma after definitive radiochemotherapy.@*Methods@#A total of 126 patients who met the inclusion criteria were enrolled in this study and divided into the salvage surgery, salvage radiochemotherapy and best supportive care.@*Results@#Fifty-eight of 126 patients received salvage esophagectomy, 52 underwent salvage radiochemotherapy and the remaining 16 patients received best supportive care. The 1-, 3-, 5-year overall survival rates of patients receiving salvage therapy were 51%, 16% and 4% for the three groups, whereas all patients in the best supportive care group died within 12.0 months (P<0.001). The 1-, 3-, 5-year survival rates in the salvage surgery and salvage radiochemotherapy groups were 48%, 20% and 7%, and 51%, 11% and 3%, respectively (P=0.473). Multivariate analysis by Cox proportional hazard model showed that T staging of recurrent tumors and salvage regimen were the independent prognostic factors in patients with locally recurrent esophageal cancer (both P<0.001). Postoperative infection occurred in 16% of the patients in the salvage surgery group, and the incidence of esophagotracheal fistula and mediastinoesophageal fistula was 10% and 6% in the salvage radiochemotherapy group.@*Conclusions@#A survival benefit can be elicited by salvage surgery or salvage radiochemotherapy in patients with locally recurrent esophageal cancer after definitive radiochemotherapy. Nevertheless, extensive attention should be paid to the management of postoperative complications in clinical practice.

Efficacy and Safety of Melphalan, Cyclophosphamide and Dexamethasone (MCD) as a Salvage Treatment for Patients with Relapsed/Refractory Multiple Myeloma / 전남의대학술지

This study investigated the efficacy and safety of melphalan, cyclophosphamide, and dexamethasone (MCD) as a salvage regimen for heavily treated relapsed or refractory multiple myeloma patients. We retrospectively analyzed a total of 27 patients who received the MCD regimen between April 2011 and November 2013. The MCD regimen consisted of oral melphalan 6.75 mg/m² on days 1–4, once-weekly dose of oral cyclophosphamide 300 mg/m2 and dexamethasone 20 mg/m² on days 1–4 and days 15–18. Each cycle was repeated every 28 days. The median age of the patients was 66 years and the MCD regimen was initiated at a median 37.7 months from diagnosis. Patients received a median of five regimens including autologous stem cell transplantation. The overall response rate was 25.9% (very good partial response 3.7%, partial response 22.2%) and 8 (29.6%) patients achieved a minor response. Median progression-free survival was 5.6 months (95% confidence interval [CI], 4.2–8.5) ; overall survival 11.7 months (95% CI, 5.4–16.6). Grade 3 or 4 neutropenia and thrombocytopenia were observed in 51.8% and 33.3%, respectively. Although the overall response rate is relatively low, the MCD regimen may have a role as a bridge to a novel regimen in heavily pretreated patients with MM.

Management of Acute Severe Ulcerative Colitis / 胃肠病学

Acute severe ulcerative colitis (ASUC) is a medical emergency that requires prompt diagnosis and treatment. Intravenous corticosteroids are the first-line medical therapy, yet over 30% of the patients are steroid-refractory. The response to steroids should be assessed on day 3 after treatment initiation; in non-responders, treatment options including ciclosporin and infliximab, or surgery should be considered. Both ciclosporin and infliximab are effective and safe salvage therapy. Colectomy is recommended if there is no improvement following 4 to 7 days of salvage therapy. Total proctocolectomy and ileal pouch-anal anastomosis is the standard surgical procedure. A three-step approach is advocated and the postoperative complications should be cared. The diagnosis and treatment of ASUC requires multidisciplinary cooperation in order to improve prognosis and reduce mortality.

Risk Factors and On-site Rescue Treatments for Endoscopic Variceal Ligation Failure / 대한소화기학회지

BACKGROUND/AIMS: The success rate of endoscopic variceal ligation (EVL) is about 85–94%. There is only a few studies attempting to determine the cause of EVL failure, and to date, on-site rescue treatments remains unestablished. This study aimed to elucidate the risk factors for EVL failure and the effectiveness of on-site rescue treatment. METHODS: Data of 454 patients who underwent emergency EVL at Chonnam National University Hospital were retrospectively analyzed. Enrolled patients were divided into two groups: the EVL success and EVL failure groups. EVL failures were defined as inability to ligate the varices due to poor endoscopic visual field, or failure of hemostasis after band ligation for the culprit lesion. RESULTS: Forty-seven patients experienced EVL failure. In the multivariate analysis, male patients, initial hypovolemic shock, active bleeding on endoscopy, and history of previous EVL were independent risk factors for EVL failure. During endoscopic procedure, we came across the common causes of EVL failure, including unsuctioned varix due to previous EVL-induced scars followed by insufficient ligation of the stigmata and inability to ligate the varix due to poor endoscopic visual field. Endoscopic variceal obturation using N-butyl-2-cyanoacrylate (48.9%) was the most commonly used on-site rescue treatment method, followed by insertion of Sangstaken Blakemore tube (14.9%), and EVL retrial (12.8%). The rescue treatments successfully achieved hemostasis in 91.7% of those in the EVL failure group. CONCLUSIONS: The risk factors of EVL failure should be considered before performing EVL, and in case of such scenario, on-site rescue treatment is needed.

Impact of Early Salvage Androgen Deprivation Therapy in Localized Prostate Cancer after Radical Prostatectomy: A Propensity Score Matched Analysis

PURPOSE: Androgen deprivation therapy (ADT) is used as a salvage treatment for men with biochemical recurrence (BCR) of prostate cancer (PCa) following initial radical prostatectomy (RP). The optimal time at which to begin salvage ADT (sADT) remains controversial. In this retrospective study, we evaluated the efficacy of initiating sADT in patients before prostate-specific antigen (PSA) values met the clinical definition of BCR. MATERIALS AND METHODS: We identified 484 PCa patients who received sADT for BCR after RP. Median follow-up was 82 months. Propensity score matching was performed based on preoperative PSA level, pathologic T stage, and Gleason score. Patients were assigned to two groups of 169 patients each, based on PSA levels at the time of sADT: Group A (without meeting of the definition of BCR) and Group B (after BCR). Kaplan-Meier survival analyses and Cox regression analyses were performed. RESULTS: The median PSA level at sADT initiation was 0.12 ng/mL in group A and 0.42 ng/mL in group B. Kaplan-Meier analyses showed that group A had favorable disease progression-free survival (DPFS) and distant metastasis-free survival (DMFS), but did not have better cancer-specific survival (CSS) than group B. In subgroup analyses, group A showed better CSS rates in the non-organ confined PCa group. In Cox regression analyses, early sADT was associated significantly with DPFS and DMFS rates, however, did not correlate with CSS (p=0.107). CONCLUSION: Early sADT after RP improved DPFS and DMFS. Furthermore, early sADT patients demonstrated better CSS in non-organ confined PCa.

A preliminary study on the salvage therapy for postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous cell carcinoma / 中国医师进修杂志

Objective To analyze the treatment effect and influencing factors of salvage therapy for postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous cell carcinoma. Methods The clinical data of 174 postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous cell carcinoma from January 2008 to December 2011 were retrospectively analyzed. The location of recurrence or metastasis, effect of salvage therapy and influencing factors were specifically focused. Results The 1-, 3-and 5-year overall survival rates after recurrence and metastasis in patients with pT3N0M0 stage thoracic esophageal squamous cell carcinoma were 35.0% , 19.3% and 13.3% respectively, and the median survival time was 7 months (95% CI 5.2 to 8.8). Single factor analysis results showed that the gender, age, location of recurrence or metastasis, distant metastasis time and salvage therapy were related to the prognosis in postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous carcinoma (P＜0.05 or＜0.01), but the weight loss (≥ 5 kg), lesion extent, lesion location, number of lymph node dissection, postoperative adjuvant treatment method and intrathoracic recurrence time were not related to the prognosis in postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous carcinoma (P＞0.05). Multivariate analysis result showed that the distant metastasis time and salvage therapy were the independent risk factors of prognosis in postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous carcinoma (P＜0.01). Conclusions Salvage therapy and distant metastasis time are independent risk factors of prognosis in postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous carcinoma, and chemoradiotherapy or radiotherapy after postoperative recurrence and metastasis in some extent could prolong the survival time.

A case of refractory hemophagocytic syndrome combined with multiple organ failure-ICU rescue experience / 天津医药

Hemophagocytic syndrome (HPS), also known as hemophagocytic lymphohistiocytosis (HLH), is a life-threatening condition of severe hyperinflammation caused by the uncontrolled proliferation of activated lymphocytes and histiocytic secreting high amounts of inflammatory cytokines. This article describes a case of refractory hemophagocytic syndrome combined with multiple organ failure. Through the review of medical history and treatment process, analysis of rescue occasion and details, and the practice on the concept of salvage therapy, our purpose is to discuss the strategy and experience that we have gained from rescuing severe refractory hemophagocytic syndrome in ICU. The key to the success rescue of this case is that we not only have carried out timely and effective early stage of initial treatment and salvage treatment, but also have had real-time monitoring and timely and effective treatment in ICU. Based on the effective infection control and comprehensive organ support, the phased treatment results of patients with HPS can be significantly improved, which provides possibility for HPS patients'survival.

Application of early repair with free tissue transplantation in hand and foot destructive injury / 中华显微外科杂志

Objective To explore the method of limb salvage therapy for hand and foot destructive injury, and to clarify the role of free tissue transplantation in limb salvage therapy in patients with hand and foot destructive injury. Methods From January, 2015 to January, 2016, 17 hand and foot destructive injuried patients were treated with limb salvage. The anterolateral thigh free flap, free fibular flap and arterial vein flap were used to repair the skin, soft tissue and bone defects. All patients were followed-up for 12 months. The appearance and function of the patients were evalu-ated after the treatment. The hand scoring criterion was the finger replantation function evaluation standard on probation of the Chinese Medical Association of Hand Surgery. The foot scoring criterion was the Maryland score system. Re-sults All flaps survived in 17 patients. One flap had vascular crisis after operation, and survived after vascular ex-ploratory operation. One case had infection postoperation and healed after several debridements. After 12 months, the functional scores were excellent in 5 cases, good in 5 cases, moderate in 3 cases and poor in 4 cases. Conclusion The early repair with free tissue transplantation can preserve limb length, cover the exposed bone and tendon, and improve the anti-infective ability, so as to improve the function of limb salvage and patient 's satisfaction.

Rifabutin-based Fourth and Fifth-line Rescue Therapy in Patients with for Helicobacter pylori Eradication Failure / 대한소화기학회지

BACKGROUND/AIMS: Optimized regimen has not yet been established for failures of multiple Helicobacter pylori (H. pylori) eradication. Hence, we aimed to evaluate the efficacy of rifabutin-based rescue therapy, at least after three eradication failures. METHODS: Twelve patients, who failed in the treatment for H. pylori eradication at least three times, were consecutively enrolled between 2007 and 2015 at Seoul National University Bundang Hospital. The rifabutin-based rescue regimen was consisted of proton pump inhibitor (PPI), rifabutin (150 mg b.i.d.), and amoxicillin (1 g b.i.d.), given for 7 or 14 days. MIC concentration test by the agar dilution method was performed on six patients prior to rifabutin-based rescue therapy. RESULTS: One patient did not take this regimen, and per-protocol (PP) analysis was performed in 11 patients. The overall eradication rate by intention-to-treat and PP analysis with rifabutin-based rescue therapy was 50.0% (6/12 patients) and 54.5% (6/11 patients), respectively. There was no difference of the eradication rate depending on the underlying disease, smoking, alcohol, number of previous eradication failures, and CYP2C19 genotype. All of the six patients were susceptible to rifabutin, but only three of them succeeded in eradicating with H. pylori. Side effects occurred in two patients (18.2%), and compliance was 90.9%. CONCLUSIONS: Even the eradication rate of rifabutin-based rescue therapy was not very good. Rifabutin-based rescue therapy could be considered as a rescue therapy, perhaps as the fourth or the fifth-line treatment option. No correlation of rifabutin sensitivity with eradication success rate of H. pylori suggests that frequent administration of high dose PPI and amoxicillin might be important.

Salvage of Unilateral Complete Ear Amputation with Continuous Local Hyperbaric Oxygen, Platelet-Rich Plasma and Polydeoxyribonucleotide without Micro-Revascularization

In many cases of complete ear amputation, microvascular surgery is required for tissue perfusion and organ survival. However, microvascular reconstruction is not always feasible in the absence of suitable vessels. Here, we present the case of a 76-year-old man who underwent complete amputation of the left ear after a collapse at home because of cardiogenic syncope. He was treated with primary replantation and underwent a postoperative salvage course including continuous local hyperbaric oxygen therapy (HBOT), platelet-rich plasma (PRP) injections, and polydeoxyribonucleotide (PDRN) injections. The ear was almost completely salvaged, with a tiny eschar at the mid-scapha on both the anterior and posterior aspects. This case demonstrates the efficacy of local HBOT with PRP and PDRN injections.

Safe and Simplified Salvage Technique for Exposed Implantable Cardiac Electronic Devices under Local Anesthesia

BACKGROUND: Skin erosion is a dire complication of implantable cardiac pacemakers and defibrillators. Classical treatments involve removal of the entire generator and lead systems, however, these may result in fatal complications. In this study, we present our experience with a simplified salvage technique for exposed implantable cardiac electronic devices (ICEDs) without removing the implanted device, in an attempt to reduce the risks and complication rates associated with this condition. METHODS: The records of 10 patients who experienced direct ICED exposure between January 2012 and December 2015 were retrospectively reviewed. The following surgical procedure was performed in all patients: removal of skin erosion and capsule, creation of a new pocket at least 1.0–1.5 cm inferior to its original position, migration of the ICED to the new pocket, and insertion of closed-suction drainage. Patients with gross local sepsis or septicemia were excluded from this study. RESULTS: Seven patients had cardiac pacemakers and the other 3 had implantable cardiac defibrillators. The time from primary ICED placement to exposure ranged from 0.3 to 151 months (mean, 29 months. Postoperative follow-up in this series ranged from 8 to 31 months (mean follow-up, 22 months). Among the 10 patients, none presented with any signs of overt infection or cutaneous lesions, except 1 patient with hematoma on postoperative day 5. The hematoma was successfully treated by surgical removal and repositioning of the closed-suction drainage. CONCLUSIONS: Based on our experience, salvage of exposed ICEDs is possible without removing the device in selected patients.
