METHODS Between 2010 and 2017, 1623 consecutive patients underwent ESD for gastric neoplasms at a single tertiary referral center. Among these, 28 patients underwent secondary ESD for a residual or locally recurrent tumor. Our analysis compared clinicopathologic factors between primary ESD and secondary ESD groups. RESULTS The en bloc resection and curative rate of resection of secondary ESD were 92.9% and 89.3%, respectively. The average procedure time of secondary ESD was significantly longer than primary ESD(78.2 min vs 55.1 min, P = 0.004), and the adverse events rate was not significantly different but trended slightly higher in the secondary ESD group compared to the primary ESD group(10.7% vs 3.8%, P = 0.095). Patients who received secondary ESD had favorable outcomes without severe adverse events. During a mean follow-up period, no local recurrence occurred in patients who received secondary ESD. CONCLUSION Secondary ESD of residual or locally recurrent gastric tumors appears to be a feasible and curative treatment though it requires greater technical efficiency and longer procedure time.展开更多

Parathyroidectomy (PTX) is indicated for patients who failed medical therapy. We reviewed the data from 184 dialysis patients who underwent PTX between January 2015 and January 2023. We aimed to evaluate the short and long term outcomes of PTX in dialysis patients, comparing the conservative 3/4 versus 7/8 techniques in this population.166 dialysis patients with secondary HPT were included. A conservative subtotal PTX (sPTX) 7/8 was performed in 72% of patients and sPTX 3/4 in 28% of them. Severe postoperative hypocalcaemiaocurred in 45 patients (27%). Hypocalcaemia was significantly more frequent in the sPTX 7/8 group (p = 0.012). One case of persistent HPT (0.6%) and 20 cases of recurrence (12%) were diagnosed. Recurrence was more frequent in the sPTX 3/4 group (15%). No deaths were reported during the perioperative period.展开更多

The study lasted two years. Patients were assigned to three groups (A, B, C) based upon basal renal function. Group A consisted of 180 patients with GFR (glomerular filtration rate) of 67 4- 16 mL/min/m2. TC (Total-Cholesterol) (-31%), LDLC (LDL-Cholesterol) (-42%), TG (triglycerides) (-36.8%) levels, and nonHDLC (non HDLC holesterol) (-41%) and TC/HDLC ratio (-40%) were significantly reduced (P 〈 0.001). GFR (+2.5%) increased significantly. No significant changes were observed in HDLC (+13%). Group B was of 744 patients, 69% (males: 514), 31% (females: 230) (median age: 70 ± 13 years), and moderate stage Ill CKD (GFR: 38 ± 12 mL/min/l.73m2). After 24 months the change of HDLC (+3.5%) was not significant, while TC (-27%), TG (-32%), LDLC (-33%), non-HDLC (33.4%), TC/HDLC (-30%), and GFR (+2.1%) were statistically significant (P 〈 0.001). Group C consisted of 180 patients, 51.6% (males: 93), 48.3% (females: 87) (median age: 72±11 years), with severe stage IV CKD (GFR: 19 mL/min/l.73m2). HDLC (+13%) was not significant, while TC (-32%), TG (-38%), LDLC (-35%), non-HDLC (-38.5%), TC/HDLC (-40%), and GFR (+2.1%) were statistically significant (P 〈 0.001). An effective but safe lipid-lowering therapy in patients with CKD, may be crucial to prevent cardiovascular events. The treatment with Dill stat~ combined with diet is to be started as soon as possible in patients with CKD in order of improving lipid and lipoprotein profile, and reducing the progression of renal damage.展开更多

Etelcalcetide (EC), which is used to treat SHPT, reduces parathyroid hormone (PTH) levels in the blood. However, the details of the effects of EC on the microstructure of cortical and trabecular bone remain unclear. This study investigated whether EC improved the cortical and trabecular bone microstructure in CKD model rats. Methods: Eight-week-old, male Wistar rats were fed with a 0.75% adenine diet for 4 weeks to establish the CDK model rats. At 20 weeks of age, the rats were divided into two groups (n = 9 - 11 in each group): CKD group (vehicle administration) and EC group (0.6 mg/kg, daily). EC was injected for 4 weeks starting at 20 weeks of age. After treatment, the biochemical tests, measurement of bone mineral density and bone strength, and evaluation of cortical and trabecular bone microstructure were performed. Results: Compared with the CKD group, the EC group showed significantly lower serum blood urea nitrogen, calcium, and inorganic phosphorus levels (p p p p p Conclusions: EC significantly improved cortical microstructure and cortical porosity, suppressing deterioration of cortical bone strength and loss of trabecular bone in the adenine-induced CKD model rats.展开更多

Partial nephrectomy and a segment resection of the small bowel were performed. Histological examination of both specimens revealed a necrotic metastasis of the primary carcinoma of the colon. Although intraluminal implantation of colon cancer cells in the renal pelvic mucosa from ureteric metastasis has been described, metastasis of a colorectal cancer in the kidney parenchyma is extremely rare and can be treated in an organ preserving manner. A complex pattern of colon cancer recurrence with unusual and rare sites of metastasis is reported.展开更多

We present a case of SFT of the kidney diagnosed through fine needle core biopsy preoperatively in a 50-year-old female and managed with laparoscopic partial nephrectomy. Due to the difficulty in discriminating between malignant and benign growth pattern of this tumor entity, a regular follow-up after conservative treatment is mandatory.展开更多

Squamous cell carcinoma risk is dramatically elevated in KTRs, occurring at rates of up 45-250 times those reported in general populations. New non-melanoma skin cancers in KTRs with a prior non-melanoma skin cancer also develop at 3-times the rate reported in non-KTRs with the same clinical history. The unique aggressiveness of SCCs in KTRs increases patient morbidity, due to the high rate of new lesions requiring treatment, frequently surgical excision. Oral nicotinamide shows promise in the chemoprevention of the especially aggressive non-melanoma skin cancers which occur in KTRs. This benefit might be conferred via its inhibition of sirtuin enzymatic pathways. Nicotinamide's concurrent hypophosphatemic effect may also partially ameliorate the disturbed calcium-phosphorus homeostasis in these patients-a putative risk factor for mortality, and graft failure. Conceivably, a phase 3 trial of nicotinamide for the prevention of non-melanoma skin cancers in KTRs, lasting at least 12-mo, could also incorporate imaging and laboratory measures which assess nicotinamide's impact on subclinical cardiovascular and chronic kidney disease risk, and progression.展开更多

文摘Over the last two decades multiple studies have demonstrated an increased incidence of additional malignancies in patients with intraductal papillary mucinous neoplasms(IPMNs).Additional malignancies have been identified in 10%-52% of patients with IPMNs.The majority of these additional cancers occur before or concurrent with the diagnosis of IPMN.The gastrointestinal tract is most commonly involved in secondary malignancies,with benign colon polyps and colon cancer commonly seen in western countries and gastric cancer commonly seen in Asian countries.Other extrapancreatic malignancies associated with IPMNs include benign and malignant esophageal neoplasms,gastrointestinal stromal tumors,carcinoid tumors,hepatobiliary cancers,breast cancers,prostate cancers,and lung cancers.There is no clear etiology for the development of secondary malignancies in patients with IPMN.Although population-based studies have shown different results from single institution studies regarding the exact incidence of additional primary cancers in IPMN patients,both have reached the same conclusion:there is a higher incidence of extrapancreatic malignancies in patients with IPMNs than in the general population.This f inding has signif icant clinical implications for both the initial evaluation and the subsequent long-term followup of patients with IPMNs.If a patient has not had recent colonoscopy,this should be performed during the evaluation of a newly diagnosed IPMN.Upper endoscopy should be performed in patients from Asian countries or for those who present with symptoms suggestive of upper gastrointestinal disease.Routine screening studies(breast and prostate) should be carried out as currently recommended for patient's age both before and after the diagnosis of IPMN.
文摘BACKGROUND To date,there are no guidelines on the treatment of solid neoplasms in the transplanted kidney.Historically,allograft nephrectomy has been considered the only reasonable option.More recently,nephron-sparing surgery (NSS) and ablative therapy (AT) have been proposed as alternative procedures in selected cases.AIM To review outcomes of AT for the treatment of renal allograft tumours.METHODS We conducted a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 Checklist.PubMed was searched in March 2019 without time restrictions for all papers reporting on radiofrequency ablation (RFA),cryoablation (CA),microwave ablation (MWA),high-intensity focused ultrasound (HIFU),and irreversible electroporation (IRE) of solid tumours of the kidney allograft.Only original manuscripts describing actual cases and edited in English were considered.All relevant articles were accessed in full text.Additional searches included all pertinent references.Selected studies were also assessed for methodological quality using a tool based on a modification of the Newcastle Ottawa scale.Data on recipient characteristics,transplant characteristics,disease characteristics,treatment protocols,and treatment outcomes were extracted and analysed.Given the nature and the quality of the studies available (mostly retrospective case reports and small retrospective uncontrolled case series),a descriptive summary was provided.RESULTS Twenty-eight relevant studies were selected describing a total of 100 AT procedures in 92 patients.Recipient age at diagnosis ranged from 21 to 71 years whereas time from transplant to diagnosis ranged from 0.1 to 312 mo.Most of the neoplasms were asymptomatic and diagnosed incidentally during imaging carried out for screening purposes or for other clinical reasons.Preferred diagnostic modality was Doppler-ultrasound scan followed by computed tomography scan,and magnetic resonance imaging.Main tumour types were: papillary renal cell carcinoma (RCC) and clear cell RCC.Maximal tumour diameter ranged from 5 to 55 mm.The vast majority of neoplasms were T1a N0 M0 with only 2 lesions staged T1b N0 M0.Neoplasms were managed by RFA (n = 78),CA (n = 15),MWA (n = 3),HIFU (n = 3),and IRE (n = 1).Overall,3 episodes of primary treatment failure were reported.A single case of recurrence was identified.Follow-up ranged from 1 to 81 mo.No cancer-related deaths were observed.Complication rate was extremely low (mostly < 10%).Graft function remained stable in the majority of recipients.Due to the limited sample size,no clear benefit of a single procedure over the other ones could be demonstrated.CONCLUSION AT for renal allograft neoplasms represents a promising alternative to radical nephrectomy and NSS in carefully selected patients.Properly designed clinical trials are needed to validate this therapeutic approach.
文摘1104 patients with Secondary Dyslipidemia and CKD (Chronic Kidney Disease) (females: 387; males: 717; aged: 70 4- 11 years) were given Diflstat with diet to evaluate efficacy and safety. The study lasted two years. Patients were assigned to three groups (A, B, C) based upon basal renal function. Group A consisted of 180 patients with GFR (glomerular filtration rate) of 67 4- 16 mL/min/m2. TC (Total-Cholesterol) (-31%), LDLC (LDL-Cholesterol) (-42%), TG (triglycerides) (-36.8%) levels, and nonHDLC (non HDLC holesterol) (-41%) and TC/HDLC ratio (-40%) were significantly reduced (P 〈 0.001). GFR (+2.5%) increased significantly. No significant changes were observed in HDLC (+13%). Group B was of 744 patients, 69% (males: 514), 31% (females: 230) (median age: 70 ± 13 years), and moderate stage Ill CKD (GFR: 38 ± 12 mL/min/l.73m2). After 24 months the change of HDLC (+3.5%) was not significant, while TC (-27%), TG (-32%), LDLC (-33%), non-HDLC (33.4%), TC/HDLC (-30%), and GFR (+2.1%) were statistically significant (P 〈 0.001). Group C consisted of 180 patients, 51.6% (males: 93), 48.3% (females: 87) (median age: 72±11 years), with severe stage IV CKD (GFR: 19 mL/min/l.73m2). HDLC (+13%) was not significant, while TC (-32%), TG (-38%), LDLC (-35%), non-HDLC (-38.5%), TC/HDLC (-40%), and GFR (+2.1%) were statistically significant (P 〈 0.001). An effective but safe lipid-lowering therapy in patients with CKD, may be crucial to prevent cardiovascular events. The treatment with Dill stat~ combined with diet is to be started as soon as possible in patients with CKD in order of improving lipid and lipoprotein profile, and reducing the progression of renal damage.

Due to the difficulty in discriminating between malignant and benign growth pattern of this tumor entity, a regular follow-up after conservative treatment is mandatory.

文摘BACKGROUND Paraneoplastic neurological syndrome manifesting as secondary Parkinson disease caused by breast cancer is extremely rare.CASE SUMMARY We report a 39-year-old primipara of 31 gestational weeks,who presented with worsening tremors,facial stiffness and speech disfluencies,and decreased limb strength.Thorough physical examinations and auxiliary tests suggested secondary Parkinson’s disease,but the pathogenesis was unknown.During the cesarean section at the 31 weeks plus 6 d,an exploration and liver biopsy revealed a metastatic,poorly differentiated adenocarcinoma.The positron emission tomography and immunohistochemical analysis confirmed a breast ductal carcinoma of stage IV.To our knowledge,only two reports have documented the association between the breast cancer and the Parkinson disease,and neither occurred in pregnant women.CONCLUSION Our case alerts the secondary Parkinson disease as the possible presentation of breast cancer,the most common malignancy during pregnancy.
文摘This article reports a case of simultaneous occurrence of 2 primary renal tumors of different histology, a transitional cell carcinoma and a renal cell carcinoma. in the same kidney. The histological, immunohistochemical and ultrastructural changes of the tumors were described. A review of the literature to date revealed this case to be rare. only 24 other cases were reported previously.
文摘Non-melanoma cutaneous carcinomas, or skin cancers, predominantly squamous cell carcinomas(SCCs), are the most common malignancies occurring in kidney transplant recipients(KTRs). Squamous cell carcinoma risk is dramatically elevated in KTRs, occurring at rates of up 45-250 times those reported in general populations. New non-melanoma skin cancers in KTRs with a prior non-melanoma skin cancer also develop at 3-times the rate reported in non-KTRs with the same clinical history. The unique aggressiveness of SCCs in KTRs increases patient morbidity, due to the high rate of new lesions requiring treatment, frequently surgical excision. Oral nicotinamide shows promise in the chemoprevention of the especially aggressive non-melanoma skin cancers which occur in KTRs. This benefit might be conferred via its inhibition of sirtuin enzymatic pathways. Nicotinamide's concurrent hypophosphatemic effect may also partially ameliorate the disturbed calcium-phosphorus homeostasis in these patients-a putative risk factor for mortality, and graft failure. Conceivably, a phase 3 trial of nicotinamide for the prevention of non-melanoma skin cancers in KTRs, lasting at least 12-mo, could also incorporate imaging and laboratory measures which assess nicotinamide's impact on subclinical cardiovascular and chronic kidney disease risk, and progression.
文摘<b><span style="font-family:Verdana;">Objective:</span></b><span style="font-family:Verdana;"> The aim of the work is to study the relationship between Red blood cell osmotic fragility and level of parathyroid hormone in patients with different stages of Chronic Kidney Disease including End Stage Renal Disease. </span><b><span style="font-family:Verdana;">Background:</span></b><span style="font-family:Verdana;"> Anaemia is one of the common complications associated with Chronic Kidney Disease (CKD) responsible for the increase in the morbidity and mortality in such patients. Several factors have been attributed to caus</span><span style="font-family:Verdana;">ing</span><span style="font-family:Verdana;"> renal anaemia, amongst which hyperparathyroidism is one of the less recognised reasons. The level of PTH in early stages of chronic kidney disease has not been much studied. The excess amount of Parathyroid Hormone (PTH) secondary to CKD has been suggested to be a causative factor for anaemia. </span><b><span style="font-family:Verdana;">Method:</span></b><span style="font-family:Verdana;"> </span><span style="font-family:Verdana;">A</span><span style="font-family:Verdana;"> </span><span style="font-family:Verdana;">number of chronic kidney disease patients were studied for the relationship between Red cell osmotic fragility and level of parathyroid hormone.</span><span style="font-family:Verdana;"> </span><b><span style="font-family:Verdana;">Results:</span></b><span style="font-family:Verdana;"> This study was conducted on a number of 111 patients with chronic kidney disease classified into three groups. The study revealed a significant fall in Hb%, along with a rise in Median Osmotic Fragility (MOF) and PTH in the CKD patients. iPTH and MOF were significantly lower in group 3 as compared with cases in group 1. Also, iPTH and MOF were significantly lower in cases in group 2 as compared with cases in group 1. </span><b><span style="font-family:Verdana;">Conclusions:</span></b><span style="font-family:Verdana;"> Based on our findings, secondary hyperparathyroidism has considerable effects on erythrocyte survival, contributing to increased fragility and anemia.</span>
