RESUMO
Bloodstream infection (BSI) is a serious clinical condition with high fatality rate. The elderly patients account for a large proportion of community-acquired BSI cases, and general practitioners should play an important role in early identification and diagnosis of community elderly BSI patients. This article reviews the status quo of diagnosis of community-acquired BSI in the elderly. Based on clinical manifestations, accessible biomarkers and blood cultures, general practitioners can make an early diagnosis and timely transfer the patients to reduce the fatality rate of community-acquired BSI.
RESUMO
Objective:To study the influence of the choice of main diagnosis on diagnosis-related groups(DRG) grouping and weight change, by taking cerebral infarction as the entry point.Methods:From January 1, 2019 to March 31, 2019, 331 patients in three DRG groups(BR25, BR23, BR21) with cerebral infarction were selected. The original group was used as the control group; the main diagnosis was exchanged with the first other diagnosis, then DRG group was used as the experimental group. The difference of the number of cases and weight between the two groups was analyzed.Results:41.4%(137/331) of the patients in the experimental group were enrolled in BZ11 with other neurological disorders associated with important comorbidities and comorbidities, and 82.5%(273/331) patients′ weight increased after diagnostic conversion.Conclusions:Choosing other diagnosis as the main diagnosis may change the weight of the disease and affect the corresponding disease benefit. In order to prevent downcoding, DRG grouping should be detailed, and DRG payment should consider how to reflect the value of difficult cases; for upcoding behavior, medical insurance center and relevant medical institutions should check the correctness of coding, and monitor in place.
RESUMO
Objective To explore the clinical effectiveness and safety of selective usage of embolic protection device to prevent distal embolization during SilverHawk atherectomy for atherosclerotic femoropo-pliteal artery disease. Methods From Jan 2014 to December 2015, 45 femoropopliteal artery atherosclerot-ic patients were treated with SilverHawk atherectomy and selective embolic protection device (EPD). The indication for EPD was instent restenosis, highly calcified lesion, suspicious of thrombosis, ulcerated le-sion, and single below-the-knee runoff. All cases who met the indication were treated with atherectomy and EPD, and those who did not meet the indication were treated with or without EPD according to the patient's choice. The embolic related complications were analyzed. Results Twenty three out of 45 patients who met the EPD indication were all treated with SilverHawk atherectomy under EPD protection, filter captured deb-ris in 17 patients (73. 9%) of the patients. The other 22 patients who did not meet the indication were di-vided into 2 groups according to the patient's choice of EPD usage, 11 were treated by atherectomy with EPD and 11 without EPD. One case out of 11 unindicated patients without EPD suffered a tibioperoneal trunk embolization and restored with catheter aspiration. For 1/11 (9. 1%) unindicated cases with EPD protec-tion, the filter captured embolization. There was a significant difference of distal embolization rate between the indicated and unindicated patients (χ2 =19. 368,P =0. 000). All filters were retrieved successfully without any distal embolization and any complications except arterial spasm occurred in 2 patients and re-stored well with nitroglycerin. Conclusions It is safe and effective for selective usage of embolic protection device to prevent distal embolization during SilverHawk atherectomy for atherosclerotic femoropopliteal artery disease.
RESUMO
Objective To investigate the safety and feasibility of carotid endarterectomy (CEA) combined with carotid artery stent angioplasty (CASA) in treating tandem stenosis of carotid artery. Methods The clinical data of 9 patients with tandem stenosis of carotid artery, who were treated at authors' hospital during the period from January 2013 to October 2014, were retrospectively analyzed. The patients included 7 males and 2 females, with a mean age of (66.0 ±4.2) years. The disease course ranged from 2 months to 36 months, with a mean of 7 months. Clinically, all patients had cerebral ischemia symptoms. Transient ischemia attack was seen in 5 patients and history of cerebral infarction was present in 2 patients. Coronary artery disease was found in 2 patients, hypertension in 6 patients and lower limb ischemia in one patient. After receiving adequate antiplatelet therapy, CEA and CASA were carried out in all patients. Results The technical success rate was 100%, postoperative residual stenosis was less than 30%, no death occurred in perioperative period. After the treatment, the clinical symptoms were improved in all 9 patients;no new stroke or cerebral hemorrhage occurred. After the treatment, 2 patients developed cerebral hyperperfusion-related symptoms such as headache and dizziness, which were much relieved at the time of discharge. The patients were followed up for 4-19 months, with a mean of (10.5±6.2) months. No recurrence of symptoms was observed . In one patient , transcranial Doppler ultrasound performed at 6 months after treatment showed that the carotid artery became moderate restenosis (50%-70%). No death occurred. Conclusion For the treatment of tandem stenosis of carotid artery, CEA combined with CASA is safe and effective, although larger sample and long-term follow-up studies are still needed to further confirm the effect.
RESUMO
<p><b>BACKGROUND</b>Totally laparoscopic aortoiliac surgery has been newly developed in China. It is known as the most complex laparoscopic technique to learn because of its high-risk procedures. Analysis of the operation-related complications of this surgery is supposed to be helpful for the early success of this technique.</p><p><b>METHODS</b>Twelve male patients (56-70 years old) with aortoiliac occlusive disease underwent totally laparoscopic aortoiliac bypass surgery (TLABS) in our institute. Clinical data and operation-related complications were retrospectively analyzed.</p><p><b>RESULTS</b>Of the 12 patients, TLABS succeeded in nine and conversion to open surgery occurred in three. One of the converted patients finally died of pulmonary infection. Operation-related complications included bleeding from arterial injury, perforation from colonic injury, graft embolism, residual aortic stenosis, and hydronephrosis. Bleeding in two patients and colonic perforation in one patient resulted in three conversions to open surgery. Intraoperative graft embolectomy and postoperative aortic stenting were performed to resolve the thrombus/embolus-referring complications. Left hydronephrosis, which was thought to result from intraoperative injury and treated with ureteric intubation drainage, recovered 6 months after TLABS.</p><p><b>CONCLUSIONS</b>Good understanding and avoidance of operation-related complications are important to guarantee the technical success of TLABS. Immediate conversion to open surgery is necessary for saving the patient's life in case of life-threatening complications.</p>

Objective To explore the safety and feasibility of calf arterial stent angioplasty to treat severe lower limb ischemia. Methods Clinical data of 13 patients in our hospital during recent 3 years were retrospectively analysed and all these patients were followed up after discharge.Of these patients there were 10 males and 3 females; mean age was (73 ±7) years; mean disease course was (8 ±4) months.Severe claudication was reported in 5 patients,rest pain in 4 patients,toe ulcer in 2 patients,gangrene in 2 patients.Stent was placed in the tibioperoneal trunk artery in 5 patients ; in the proximal part of peroneal artery in 3 patients; in the tibioperoneal trunk and proximal peroneal artery in 2 patients; in the anterior tibial artery in 2 patients; in the posterior tibial artery in one patient.Simultaneous endovascular treatment of femoral/popliteal arterial disease was done in 11 patients. Results All the procedures were successful and the treated arteries kept patent on discharge of patients.Claudication distance increased to be above 500 meter in 5 patients; rest pain relieved in 4 patients ; toes ulcer reduced in 2 patients,feet gangrene kept dry till discharge in 2 patients.Postoperative ABI increased in all patients.Patients were followed-up of mean (6.9 ± 2.2) months.One patient with previous toe gangrene underwent amputation due to recurrent pain while the stent in anterior tibial artery kept patent after 6 months discharge.In the other patient gangrene toe had fallen off and the wound healed.Two patients with toe ulcer had a total recovery and patients with previous rest pain had no recurrent symptoms. Conclusions Below knee arterial stent angioplasty is a safe and effective method in the treatment of severe lower limb ischemia.
RESUMO
Objective To investigate the effect and safety of autologons bone margow-mononuclear cell (BM-MNC)transplantation after the bone marrow stimulation in patients with thromboangiitis obliterans (TAO).Methods The bone marrows of 12 patients were stimulated by an injection of the recombinant human granuloeyte-macmphage colony-stimulatory factor(GCSF)for 3-5 days.150-200 ml bone marrow was drown from the iliac spine and the autologous BM-MNC were obtained in each patients.Fifteen lower limbs of 12 patients received implantation of the autologous BM-MNC by an intramuscular iniecdon.A series of subjective indexes(including improvement of pain and cold sensation)and objeetive indexes [including increase of ankle braehial index(ABI),transcutaneons oxygen pressure(TcPO2)and improvement of foot skin ulcer] were used to evaluate the effects.Results The outcomes were evaluated after 2 months of transplantation.The pain-relief rate and the cold feeling improvement rate were 86.7%(13/15)and 93.3%(14/15)respectively.The ABI were 0.38 ±0.05 vs.0.61 ±0.14(P<0.05)before transplantation and 2 months after transplantation respectively.increased in 66.7%(10/15)limbs.The TcPO2 of the ischemic legs increased from(27.47±2.85)mm Hg to(43.53 ±8.38)mm Hg(t=-7.03,P<0.05)after the transplantation,and the improvement rate of TcPO2 was 93.3%(14/15).Skin ulcers in improved in 8/9 limbs.Twelve patients were followed up for all average period of 10 months.The patients'symptoms improved in 80.0%(12/15)limbs,as to the objective index the ABI was0.57±0.13,TcPO2 was(42.07 ±7.81)mm Hg,which improved significandy compared to before treatment(t=-5.33,-7.80,Ps<0.05).skin ulcer healing rate was 66.7%(6/9).The ischemic symptoms in 2 patients were not relieved.There WBS no mortality and high level amputation in all subjects.The complications,such as proliferative retinopathy,malitpmnt tumor,myocardial infarction,stroke or hemangioma were not found in any patients.Conclusion In patients with TAO,intramuscular transplantation of autologous BM-MNC after the bone marrow stimulation has advantages of less bone marrow aspiration,more mononuclear cell content and relatively high safety.It may be a new and effective method to alleviate symptoms and accelerate the healing of skin ulcer.
RESUMO
ObjectiveTo analyze the surgical treatment of visceral artery aneurysm (VAAs).MethodClinical data of 19 patients surgically treated for visceral artery aneurysm in our hospital from Feb 2002 to Jun 2010 were reviewed. There were 7 cases of splenic, 1 of right hepatic, 1 of left gastric,3 of pancreaticoduodenal,2 of gastroduodenal, 1 of superior mesenteric, 1 of middle colic, 1 of left colic and 2 of renal artery aneurysms. Rupture of the aneurysm occurred in 12 patients. Transcatheter arterial embolization was performed in 13 cases, other 6 cases received open surgical treatment.ResultsFour patients suffered from recurrent bleeding after first embolization, 2 of those received surgery to stop bleeding, another 2 were successfully managed by second embolization.Bleeding were rapidly controlled in 8 ruptured patients associated with shock. Duodenum incomplete obstruction developed in 1 patient after pancreaticoduodenal artery embolization, another 2 patients suffered from partial splenic infarction after splenic artery operation. 18 cases were followed-up from 2 to 103 months without aneurysm recurrence.ConclusionsEndovascular embolization and open surgery for VAAs are safe and effective, endovascular intervention and embolization is especially life saving for ruptured pseudo-aneurysm cases.
RESUMO
BACKGROUND: Electrostatic layer-by-layer (LbL) self-assembly is a simple, effective and novel approach to carrying macromolecules into microcapsule carriers.OBJECTIVE: To prepare chitosan (CS) microcapsules to control the releasing of heparin (Hep) by LbL.METHODS: CS microspheres were fabricated by a sodium sulfate-based precipitation process and then used as positively charged templates for polyelectrolyte multilayer coatings to carry heparin by the LbL self-assembly technique. The polycation was CS and the polyanion was Hep. The microcapsule was formed via coating {CS/Hep}3 on CS hydrogel template. The microcapsules composed of {CS/ Hep}3 on CS hydrogel templates were confirmed by fluorescence inverted microscopy, confocal laser scanning microscopy and laser particle size analysis. The assembly of polyelectrolyte layers on CS hydrogel microspheres was monitored by Zeta Potential Analyzer.RESULTS AND CONCLUSION: The resulting microcapsules were about 1 μm in average diameter, and allowed spontaneous loading of heparin through electrostatic interaction, with the encapsulation efficiency and carrying capacity of 83.8% and 3.05%, respectively.
RESUMO
Objective To evaluate the role of transcranial Doppler (TCD) in carotid endarterectomy and the effect of carotid endarterectomy on extracranial carotid artery stenosis.Methods From January 2002 to December 2008, fifty eight patients (40 males and 18 females)with mean age of 64.5 years were treated in our hospital. Of these patients, forty had symptoms of cerebral ischemia, eighteen were asymptomatic. All the patients had 70% and up carotid artery stenosis. Forty one patients underwent simple suture closure of the arterial incision while nine patients had angioplasty with arterial patch (polyester) and eight with autologous great saphenous vein. TCD monitoring was used in the surgery of 32 patients excluding two patients using arterial shunt. Results Surgery was successful in all 58 cases except for deflected tongue-protrusion in five patients after operation, of which three recovered conservatively and two recovered after administration of cortical steroids for two weeks. Cerebral ischemic symptoms improved to a certain degree in all the 40 preoperative symptomatic patients. Cerebral hyperperfusion occurred in five of no TCD-monitoring patients ( 19.2% ), no hyperperfusion was found in TCD-monitored patients. Fifty three patients were followed up for a mean time of 42.5 months. Five patients died and three patients had carotid artery restenosis, of which two underwent PTA and stenting, one is still under surveillance.Conclusions Carotid endarterectomy is a safe and effective procedure for treating extracranial carotid artery stenosis. TCD monitoring is valuable for determining the use of arterial shunt and preventing postoperative cerebral hyperperfusion.
RESUMO
Objective To evaluate surgical treatment of lower limb ischemia due to combination of thromboangiitis obliterans (TAO) and arteriosclerosis obliterans (ASO). Methods Clinical data of six patients suffering from lower limb ischemia due to TAO and ASO were retrospectively analyzed. All patients had a history of smoking, and complained of rest pain. Three patients had foot ulcer and one had toe gangrene. Two patients reeeived aortie artery endartereetomy combined with FIFE graft bypass to deep femoral artery and below knee popliteal artery plus saphenous vein graft bypass to tibial artery. One patient received aortic thrombectomy and endarterectomy plus aortofemoral and femoropopliteal PTFE graft bypass. One patient with a history of left graft thrombosis after aorto-bifemoral arterial bypass using PTFE graft before admission underwent left PTFE graft thrombectomy via left groin and left deep femoral artery endarterectomy followed by femoropopliteal arterial bypass. One patient received left common iliac artery endarterectomy plus left profound femoral PTFE graft-left anterior tibial arterial bypass using in situ great saphenous vein graft. One patient received right to left femorofemoral arterial bypass using PTFE graft to left posterior tibial artety bypass using reversed great saphenous vein graft. Results One patient receiving aortoiliac thrombectomy and endarterectomy with aortofemoropopliteotibial arterial bypass suffered from graft thrombosis several hours after operation and emergency thrombectomy with distal posterior tibial arteriovenous fistulization was performed. The rest pain disappeared in 5 patients and partially relieved in one. All the grafts were patent on discharge. The foot ulcer reduced in 3 patients. All the 6 patients were followed up with a mean of 6. 5 months. 3 foot ulcers healed. One patient eventually received below knee amputation due to foot gangrene three months later. Conclusion Although it is difficult to treat combined limb ischemia of TAO and ASO, satisfactory results could be achieved when proper surgical procedure is adopted.
