OBJECTIVE To explore the application effects of the multi-disciplinary treatment （MDT）-based continuous pharmaceutical care system in patients undergoing anti-infection treatment. METHODS This research team innovatively developed an MDT continuous pharmaceutical care system， which was applied to cases of anti-infection treatment following MDT due to infection， aiming to innovate the continuous medication supervision model. A retrospective analysis method was used to collect data from 150 patients in the intensive care unit who underwent conventional anti-infection MDT consultations from January to October 2021 in Banan Hospital Affiliated to Chongqing Medical University， serving as the control group， and 130 patients in the intensive care unit who were under the MDT continuous pharmaceutical care system from January to October 2022 were selected as the intervention group. The general information of the patients， the information continuous tracking management， the outcomes of anti- infection treatment， adverse drug reactions， antibacterial drug management indicators， and the degree of satisfaction of relevant medical staff with the clinical pharmacists’ pharmaceutical services were compared between the two groups. RESULTS Comparison of general information between the two groups showed no statistically significant differences （P＞0.05）. The proportion of continuous tracking management in the intervention group was significantly higher than in the control group （P＜0.01）， and the differences in the initiators and reasons for continuous tracking management between the two groups were statistically significant （P＜0.05）. The intervention group had better outcomes in anti-infection treatment compared to the control group （P＜0.05）. The antibacterial drug management indicators （total length of hospital stay， duration of antibacterial drug use， total drug costs， and amount of antibacterial drugs used） in the intervention group were significantly lower than in the control group， while overall degree of satisfaction among medical staff was significantly higher in the intervention group than in the control group （P＜0.05）. No statistically significant differences were found in adverse reaction occurrence and antibacterial drug costs between the two groups （P＞0.05）. CONCLUSIONS The application of this system in patients who underwent anti-infection treatment after MDT can achieve continuous multi-disciplinary tracking management with clinical pharmacists at the core， which is beneficial for promoting the follow-up efficiency of the MDT team， raising the quality of clinical pharmacists’ pharmaceutical services， strengthening treatment outcomes， and promoting the rational use of antibacterial drugs in clinical practice.

Objective:To investigate the clinicopathologic features and differential diagnosis of ureteral fibroepithelial polyps.Methods:The clinicopathologic features and prognosis of ureteral fibroepithelial polyps with complete data retrieved from the pathology database of the Institute of Urology, Peking University from January 2013 to December 2021 were collected and analyzed. All HE staining sections were reviewed by a senior urologic pathologist. Immunohistochemical analysis was done in some cases for differential diagnosis. The clinical, imaging and outcome data were collected, and discussed together with relevant literature.Results:There were 45 patients with complete clinicopathologic data, including 34 males and 11 females (male: female=3.1∶1.0), with a median age of 36 (range 13-80) years. Preoperative diagnosis included polyp in 23 cases, tumor in 19 cases and calculi in 3 cases. The main clinical symptoms were hematuria (13 cases), low back and abdominal pain (9 cases) and no symptoms (9 cases). There were 29 cases of multiple polyps, 16 cases of single polyp; 32 cases were on the left side, 13 cases were on the right side; 29 cases of upper polyps, 9 cases of middle polyps, and 6 cases of lower polyps. Twenty-seven patients had no related urologic history, 10 patients had history of urolithiasis, and the rest had history of stents, strictures or tumors. Local ureteral resection and anastomosis were the most common treatment (20 cases), followed by ureteroscopic polypectomy (12 cases). The patients were followed up from the pathological diagnosis to the cut-off time: 4 cases were lost to follow-up, and the remaining 34 cases were followed up for 3 to 85 (mean 60 months). One case had polyp recurrence after 3 months, and the other case had polyp recurrence after 2 years. Fibroepithelial polyps had a variety of gross manifestations, ranging from elongated polyps or small papillary and polypoid to large papillary masses. Microscopically, they were divided into type 1, type 2 and type 3, and the type 3 was the most common type (28 cases). In this study, there were 41 cases of simple fibroepithelial polyp, 2 cases of malignant transformation of polyps into urothelial carcinoma, one case of polyps with urothelial carcinoma, and one case of polyp with surface urothelial carcinoma in situ; the stroma showed myofibroblastic proliferation.Conclusions:The clinical manifestations and morphologic characteristics of ureteral fibroepithelial polyps are diverse. The three microscopic types are easily confused with many benign and malignant ureteral diseases, such as inflammatory polyps, adenocystitis, papilloma, etc. Awareness of the key differentiation points and judicious use of immunohistochemistry will be helpful for the diagnosis and differential diagnosis.

Objective:To present the clinical characteristics and treatment on patients with ectopic adrenocorticotropic hormone(ACTH) syndrome (EAS) caused by the retroperitoneal paraganglioma.Methods:The clinical data of a case of EAS caused by retroperitoneal paraganglioma were analyzed retrospectively, and the related literature at home and abroad was reviewed.Results:The 53-year-old female patient was admitted to endocrinology department due to a fifteen-year history of hypertension, accompanied by fatigue for three months, headache and dizziness for one month. The laboratory data demonstrated severe hypokalemia, high level of serum and urinary cortisol, while the ACTH level remained unsuppressed. The 24 h urinary vanillyl mandelic acid (VMA) and serum free methoxyepinephrine (MNs) level were elevated. The abdominal computed tomographic scan suggested a retroperitoneal mass next to the abdominal aorta. After the retroperitoneal tumor resection was performed, immunohistochemical staining of the tumor revealed Syn (+ ), CgA (+ ), ACTH (focal + ). By the retrospective analysis of 22 similar cases from 16 papers and the case summarized above, we found that most patients with EAS caused by the paraganglioma could demonstrate the typical clinical features of Cushing′s syndrome, while lack of the manifestation of paraganglioma. Therefore, preoperative preparations for paraganglioma were usually neglected.Conclusions:Ectopic ACTH syndrome (EAS) originating from paraganglioma is very rare. To improve the diagnosis rate, examination for catecholamine, MNs and 24 h urinary VMA before surgery in patients with EAS is suggested. Considering surgical resection as the optimal treatment, comprehensive preoperative preparations for both paraganglioma and Cushing′s syndrome are significant. A genetic test for pheochromocytoma/ paraganglioma and lifelong postoperative follow-up are also recommend.

Objective:To explore the features of free uroflow(FF) curve patterns in female patients with detrusor underactivity(DU) and their clinical significance.Methods:Data of 275 adult female patients with lower urinary tract symptoms(LUTS) underwent urodynamic studies(UDS) at urology center of our hospital from June 2014 to June 2016 were analyzed retrospectively. The uroflow curve patterns of patients with DU were classified and analyzed in the context of parameters of FF, cystometry (CM), and pressure-flow study(PFS). The prevalence of each abnormal uroflow curve pattern in DU patients were calculated and compared with those in non-DU patients.Results:No bell-shaped curve was found in 141 patients with DU. The abnormal curve patterns can be divided into 5 types: Type Ⅰ (bell-shaped curve with saw tooth) in 20 cases (14.2%), Type Ⅱ (box-like curve) in 34 cases (24.1%), Type Ⅲ (triangle curve with decreasing slop) in 62 cases(43.9%), Type Ⅳ (triangle curve with increasing slop) in 4 cases (4.3%), Type Ⅴ (tide-wave curve)in 19 cases (13.5%). Maximum flow rate of free uroflow(Q max.FF) of type Ⅰ [(28.4±9.7) ml/s] was significantly greater than that of type Ⅱ, Ⅲ and Ⅴ[(17.0±4.1), (15.8±5.4) and (12.9±6.4) ml/s, P<0.05]. Flow time of free uroflow(FT.FF) of type Ⅲ and Ⅴ [(43.7±17.2) and (50.1±28.9)s] were significantly longer than that of type Ⅰ and Ⅱ [(18.5±7.3)s and (27.2±9.7)s, P<0.05]. Post voided residual > 50ml was noted in 19 cases (30.6%) of type Ⅲ, 7 cases (36.8%) of type Ⅴ, 1 case (2.9%) of type Ⅱ and no one in type Ⅰ and Ⅳ. Abnormal manifestations in cystometry mainly included bladder hypersensitivity, detrusor overactivity, and stress urinary incontinence. Detrusor pressure at Q max (Pdet.Q max) of type Ⅴ [(7.4±5.0) cmH 2O] was significantly lower than that of type Ⅰ, Ⅱ, Ⅲ [(11.8±6.7), (12.0±5.3), (12.1±5.0) cmH 2O, P<0.05]. Among 134 cases of non-DU, there were type Ⅰ curves in 88 cases (65.7%), type Ⅱ curves in 4 cases (2.9%), type Ⅲ curves in 15 cases (11.2%), type Ⅳ curves in 1 cases (0.7%), type Ⅴ curves in 7 cases (5.2%). And normal bell-shaped curves in 19 cases(14.2%). The prevalence of type Ⅱ, Ⅲ and Ⅴ in DU patients was significantly higher than that in the non DU patients ( P<0.05). Conclusions:This study reveals that the characteristics of reduced detrusor contractility and duration, prolonged bladder emptying or incomplete emptying can be reflected in the patterns of free uroflow curve in female patients with DU. The abnormalities of these free uroflow curve patterns, especially type Ⅱ, Ⅲ and Ⅴ will be helpful in preliminarily screening DU in females.

Objective    To evaluate the early and mid-term safety of transcatheter aortic valve replacement via transfemoral (TF), transapical (TAp) and transsubclavian (TSc) approaches by meta-analysis. Methods    We systematically searched the clinical comparative trials published from inception to June 2019 from PubMed, Web of Science, EMbase and The Cochrane Library, to evaluate the safety of transcatheter aortic valve replacement through TF, TAp or TSc approaches. The information of all-cause mortality at 30 days, 1 year, 2 years and the incidence of common complications at 30 days after operation (including pacemaker-dependent block, major vascular complications, severe bleeding events, acute renal injury and stroke) were exacted, and a meta-analysis was conducted by RevMan 5.3 software. Results    This study included 11 literatures, with a total of 7 833 patients, among whom 5 348 patients were treated by TF TAVR, 1 796 patients by TAp TAVR and 689 patients by TSc TAVR. The results of the meta-analysis were as follows: (1)  at 30 days after operation, the mortality of TF and TSc approaches were lower than that of the TAp approach (TF vs. TAp:OR=0.57, 95%CI 0.39-0.84, P=0.004; TSc vs. TAp: OR=4.12, 95%CI 1.93-8.79, P=0.000 3). There was no statistical difference between the TF and TSc approaches (TF vs. TSc: OR=0.98, 95%CI 0.38-2.51, P=0.97); at 1 year, there was no statistical difference in mortality among the three approaches (P>0.05); at 2 years, there was no statistical difference between TSc and TF or TAp approaches (TF vs. TSc: OR=1.21, 95%CI 0.95-1.54, P=0.13; TSc vs. TAp: OR=1.02, 95%CI 0.76-1.36, P=0.91). (2) The incidence of acute kidney injury after TF approach was lower than that of the TAp approach (OR=0.30, 95%CI 0.22-0.41, P<0.000 01). (3) There was no statistical difference in major vascular complications between TSc and TF or TAp approaches (TF vs. TSc: OR=0.75, 95%CI 0.38-1.49, P=0.41; TSc vs. TAp: OR=1.37, 95%CI 0.56-3.32, P=0.49). (4) There was no statistical difference in severe bleeding events between TF and TSc (OR=0.97, 95%CI 0.53-1.76, P=0.92). (5) There was no statistical difference in the incidence of postoperative stroke, pacemaker dependent block among the three approaches (P>0.05). Conclusion    TAp and TSc approaches are safe and effective. They are not only an alternative to TF approach, but also the first choice in some patients with poor condition of iliofemoral artery.

Objective: To assess the safety and feasibility of the application of the laparoscopic modality in the perioperative treatment of central liver tumors. Methods: Collecting all the clinical information of a total of 40 patients with central liver tumors who received laparoscopic resection treatment carried out at Department of Hepatological Surgery of People′s Hospital of Hunan Provincial from January 2016 to December 2018 to take a retrospective review. There were 19 males and 21 females.The age was (59.5±14.5) years (range: 15 to 71 years) . There were 26 cases of primary hepatic carcinoma (24 cases of hepatocellular carcinoma, 2 cases of cholangiocellular carcinoma) , 8 cases of hepatic cavernous hemangioma, 1 case of metastatic hepatic carcinoma, 5 cases of hepatocellular adenoma. The maximum diameter of tumors were (6.2±2.9) cm (range: 2 to 13 cm) . The patient′s information about hepatectomy methods, blocking mode and time of blood flow, operation time, intraoperative blood loss, intraoperative blood transfusion rate, post-operative hospitalization time, perioperative reoperation and postoperative complications were collected. Results: A total of 40 patients all were treated with laparoscopic surgery. The surgical procedure was as follows: 2 patients received the right hepatic lobectomy (Ⅴ, Ⅵ, Ⅶ and Ⅷ segments) , 2 patients received the left hepatic lobectomy (Ⅱ, III and Ⅳ segments) , 13 patients received mesohepatectomy (Ⅳ, Ⅰ and Ⅷ segments) , 2 patients received left hepatic trisegmentectomy (Ⅱ, Ⅲ, Ⅳ and Ⅷ segments) , 2 patients received right hepatic trisegmentectomy (Ⅳ, Ⅴ, Ⅵ, Ⅶ and Ⅷ segments) , 7 patients received Ⅷ segmentectomy, 1 patient received Ⅳ segmentectomy, 3 patients received Ⅴ and Ⅷ segmentectomy, 5 patients received hepatic caudate lobe resection (Ⅰ, Ⅸ segments) , and 3 patients received local tumors resection.Pathological results: there were 26 cases of primary hepatic carcinoma (24 cases of hepatocellular carcinoma, 2 cases of cholangiocellular carcinoma) , 8 cases of hepatic cavernous hemangioma, 1 case of metastatic hepatic carcinoma, 5 cases of hepatocellular adenoma; the pathological reports of all malignant tumor cases all showed negative incisal edge. The operative time was (333±30) minutes (range: 280 to 380 minutes) ; the intraoperative hepatic portal occlusion period was (58±13) minutes (range: 30 to 90 minutes) ; the intraoperative hemorrhage was (173±129) ml (range: 20 to 600 ml) ; the intraoperative blood transfusion rate was 2.5% (1/40) ; the postoperative incidence of bile leakage was 2.5% (1/40) , the hospital discharge of 1 patient with bile leakage was approved after conservative treatments like T pipe decompression and adequate drainage; there was 1 case of abdominal infection and 1 case of pulmonary infection, both of which were discharged from the hospital with conservative treatments; there were no other serious postoperative complications. The postoperative hospital stay was (10.7±2.7) days (range: 6 to 16 days) ; there were no perioperative mortality and reoperation cases. Conclusion In the centers with abundant laparoscopic hepatectomy experiences, the laparoscopic resection is proved to be safe and feasible in the perioperative treatments of central liver tumors by the highly selective cases, the adequate preoperative assessment and reasonable surgical techniques and approach.

Objective: To explore the clinical application value of enhanced recovery after surgery (ERAS) in the laparoscopic surgery for cholecystolithiasis comorbid with choledocholithiasis. Methods: The prospective study was conducted. The clinicopathological data of 52 patients with cholecystolithiasis comorbid with choledocholithiasis who were admitted to the Third Affiliated Hospital of Zunyi Medical University from September 2016 to September 2018 were collected. Patients were divided into 2 groups by random number table: patients in observation group received laparoscopic cholecystectomy + choledocholithotomy + choledochoscopic exploration + T-tube drainage (or primary suture of common bile duct) and perioperative management guided by the concept of enhanced recovery after surgery (ERAS), and patients in control group received traditional perioperative management. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) postoperative complications; (4) postoperative pain scores; (5) changes in hepatic function and blood routine during perioperative period. Follow-up using outpatient examination and telephone interview was performed to detect complications during the postoperative 6 months up to March 2019. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the paired t test or repeated ANOVA. Count data were described as absolute numbers and percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results: Fifty-two patients were screened for eligibility, including 20 males and 32 females, aged 25-68 years, with an average age of 53 years. There were 30 patients in the observation group and 22 in the control group. (1) Surgical situations: the operation time and volume of intraoperative blood loss were (133±19)minutes and (47±21)mL in the observation group, and (136±22)minutes and (49±23)mL in the control group, respectively, showing no significant difference between the two groups (t=-0.386, -0.211, P>0.05). (2) Postoperative situations: time to out-of-bed activity, time to initial food intake, time to first anal flatus, duration of postoperative hospital stay, and hospital expenses were (18±4)hours, (19±5)hours, (28±2)hours, (4.0±1.0)days, and (1.82±0.22)×10⁴ yuan in the observation group, and (29±7)hours, (46±9)hours, (37±4)hours, (6.6±1.6)days, and (2.25±0.29)×10⁴ yuan in the control group, respectively, showing significant differences between the two groups (t=-7.054, -14.169, -9.426, -6.582, -5.809, P<0.05). (3) Postoperative complications: 1 of 30 patients in the observation group had postoperative biliary leakage, with a postoperative complication rate of 3.3%, and was cured after symptomatic support treatment. Six of 22 patients in the control group had postoperative complication, with a postoperative complication rate of 27.3%, including 2 of biliary leakage, 1 of hemorrhage, 1 of abdominal infection, 1 of pulmonary infection, 1 of urinary infection, and they were cured after symptomatic support treatment. There was a significant difference between the two groups (χ²=4.358, P<0.05). (4) Postoperative pain scores: from postoperative 6 hours to 48 hours, the postoperative pain score changed from 2.4±0.7 to 1.9±0.9 in the observation group, and from 4.1±0.7 to 2.9±0.9 in the control group, respectively, showing a significant difference in the changing trend between the two groups (F=78.053, P<0.05). (5) Changes in hepatic function and blood routine during perioperative period: from preoperation to postoperative 3 days, levels of alamine aminotransferase (ALT), aspartate transaminase (AST), gamma-glutamyltransferase (GGT), total bilirubin (TBil), and count of white blood cells in the observation group changed from (77±20)U/L to (53±12)U/L, from (85±22)U/L to (61±17)U/L, from (166±39)U/L to (55±24)U/L, from (40±13)μmol/L to (29±12)μmol/L, from (7.0±2.0)×10⁹/L to (6.8±1.9)×10⁹/L, and changed from (79±23)U/L to (62±14)U/L, from (88±24)U/L to (64±17)U/L, from (179±34)U/L to (74±29)U/L, from (45±13)μmol/L to (35±12)μmol/L, from (7.9±2.4)×10⁹/L to (7.5±1.9)×10⁹/L in the control group, respectively. The levels of ALT, AST, GGT, TBiL, and count of WBC showed increasing at postoperative 1 day, and decreasing at postoperative 3 days. There was no significant difference in the changing trend between the two groups (F=0.058, 0.471, 3.021, 1.593, 2.172, P>0.05). Conclusion ERAS is safe and effective in the laparoscopic surgery for choledocholithiasis comorbid with cholecystolithiasis.

Objective To establish a test of autoantibody-panel for the diagnosis of autoimmune cerebellitis (AC) and determine the prevalence of AC in patients with cerebellar ataxia of unknown etiology.Methods Autoantibody screening tests with indirect immunofluorescence were performed in serum and cerebrospinal fluid (CSF) samples of 400 previously'idiopathic'Chinese patients with cerebral ataxia (inpatients and outpatients in Peking Union Medical College Hospital or referred from hospitals of Beijing Encephalitis Group from 2016 to 2018).Immunotherapy was given to autoantibody positive patients and the effectiveness of immunotherapy was assessed.Detailed AC autoantibodies panel included anti-glutamate decarboxylase 65 (GAD65) antibody,anti-Tr (delta notch-like epidermal growth factor-related receptor (DNER)) antibody,anti-zinc finger protein 4 (ZIC4) antibody,anti-inositol 1,4,5-trisphosphate receptor 1 (ITPR1) antibody,anti-homer protein homolog 3 (Homer 3) antibody,anti-neurochondrin (NCDN) antibody,anti-carbonic anhydrase-related protein (CARP) antibody and anti-Purkinje cell antibody 2 (PCA2) antibody.Results Eight out of 400 (2％) ataxia patients were positive for this AC panel tests,of whom two were positive for anti-GAD65 antibody,two for anti-Tr antibody,one for anti-PCA2 antibody,one for anti-Homer 3 antibody and two were positive for serum anti-NCDN antibody.Autoantibodies against ZIC4,ITPR1 and CARP were not detected in this cohort.Two of the eight ataxia patients also presented with limbic encephalitis,and only one anti-GAD antibody patient was screened with underlying small cell lung carcinoma (SCLC).All the eight patients received immunotherapy and four experienced partial response.Conclusions Autoimmune cerebellitis is the cause of acquired cerebellar ataxia.Tests of autoantibodies associated with AC have diagnostic value for paraneoplastic and non-paraneoplastic cerebellar ataxia.Immunotherapy may yield partial response in patients with AC.

Objective To approach the spine MRI features and its possibility of etiology for refractory lower urinary tract symptoms(LUTS) in female patients.Methods We conducted prospectively a cross sectional description study of female patients with refractory LUTS during January 16 through March 27 in 2017 based on a urologist's outpatient work.The including criteria were adult female patients with refractory LUTS which defined as having LUTS more than three months and having poor response to behavior therapy and medication treatment.The excluding criteria were patients having evidence of infection,tumor,stone in urinary tract,any central nerve system diseases,or any other diseases may potentially producing LUTS.Data collected included patients demographic information,main complains,present disease features,disease history,physical examination,urine routine,urodynamic study and spine MRI.The characteristics of clinical manifestation,urodynamic study and spine MRI were analyzed.Results During the time span of study,totally 70 cases had been diagnosed as having refractory LUTS and had qualified data of clinical recordings,urodynamic study and spine MRI.Among these 70 cases,63 (90.9％) had storage phase symptoms,11 (15.7％) had voiding phase symptoms,8 (11.4％) had postmicturition symptoms,12 (17.1％) also had disorders in defecating,45 (64.3％) had pain in lower abdomen or pelvic region.69 cases (98.6％) had urodynamic disorders,33 (47.1％) had oversensitivity of bladder,12 (17.1％) had smaller bladder volume,16(22.9％) had detrusor overactivity,15 (21.4％) had bladder outlet obstruction,39(55.7％) had detrusor underactivity.69 cases(98.6％)had spine MRI abnormalities,54(77.1％) had sacral nerve lesions,49 (70.0％) had cervical lesions,48 (68.6％) had lumbar lesions,4 had thorathic lesions.Conclusions The present study revealed extraordinary high prevalence of abnormality in urodynamic parameters and spine MRI in female patients with refractory LUTS,which implies possibility that the refractory LUTS are caused by lesions in spinal nerve system.

Objective: To study the clinical characteristics, image findings, therapeutic method and prognosis of metanephric adenoma. Method: The clinical characteristic, image findings, operation methods and prognosis of 16 metanephric adenoma patients treated at Department of Urology, Peking University First Hospital from January 2004 to March 2016 were analyzed retrospectively. Results: There were 6 male and 10 female patients in the study. The mean age of patients was 33.7 years (ranging from 14 to 83 years). Two patients came to the hospital because of fever, while other 14 patients had no symptoms and found renal tumor by medical examination. One case was found polythemia vera and another 1 case showed mild anemia. Serum creatine of all the cases were in normal range. The tumor of 11 cases were at left side and 5 cases were at right. All patients took urinary tract ultrasound. Fifteen patients took CT examination. Among them, 14 cases were solid mass and 1 case was cystosolid.CT value was (41±4) HU. CT scan showed that the tumor was slight enhanced and CT value increased to (77±9) HU. Six patients took MRI examination. The MRI showed high or low signal of T1WI or T2WI scans.Tumor size was (4.7±3.9)cm (ranging from 1.7 to 17.5 cm). All 16 patients took operation and 11 of them took laparoscopic surgery while the other 5 cases took open surgery. Eleven cases took partial nephrectomy, 4 cases took nephrectomy and 1 case took nephroureterectomy. The surgical procedures were all successful and no complications occured during perioperative period. All cases were all confirmed metanephric adenoma by postoperative pathology and surgery cut edge were all negative. Immunohistochemical study showed that the positive rate of Vimentin, CD57, AE1/AE3, WT1, CK7 and AMACR respectively were 16/16, 15/16, 12/16, 10/16, 3/16 and 2/16. The median follow-up time of 16 cases was 44 months (ranging from 8 to 125 months) and none had recurrence or metastasis.One case died 125 months after surgery because of advanced age(83 years old). Conclusions Metanephric adenoma is difficult to be diagnosed relying on clinical characteristics and image features. Pathology can help confirm the diagnosis. Partial nephrectomy is the first choice for operation and can achieve good prognosis. But it still needs a regular follow-up.
