  1. Home mechanical ventilation in childhood-onset hereditary neuromuscular diseases: 13 years' experience at a single center in Korea.

    Young Joo Han

    Full Text Available Children with hereditary neuromuscular diseases (NMDs are at a high risk of morbidity and mortality related to respiratory failure. The use of home mechanical ventilation (HMV has saved the lives of many children with NMD but, due to a lack of studies, dependable guidelines are not available. We drew upon our experience to compare the various underlying NMDs and to evaluate HMV with regard to respiratory morbidity, the proper indications and timing for its use, and to develop a policy to improve the quality of home noninvasive ventilation (NIV.We retrospectively analyzed the medical records of 57 children with childhood-onset hereditary NMDs in whom HMV was initiated between January 2000 and May 2013 at Seoul National University Children's Hospital. The degree of respiratory morbidity was estimated by the frequency and duration of hospitalizations caused by respiratory distress.The most common NMD was spinal muscular atrophy (SMA, n = 33. Emergent mechanical ventilation was initiated in 44% of the patients before the confirmed diagnosis, and the indicators of pre-HMV respiratory morbidity (e.g., extubation trials, hypoxia, hospitalizations, and intensive care unit stay were greater in these patients than in others. The proportion of post-HMV hospitalizations (range, 0.00-0.52; median, 0.01 was lower than that of pre-HMV hospitalizations (0.02-1.00; 0.99 (P < 0.001. Eight patients were able to maintain home NIV. The main causes of NIV failure were air leakage and a large amount of airway secretions.The application of HMV helped reduce respiratory morbidity in children with childhood-onset hereditary NMD. Patients with SMA type I can benefit from an early diagnosis and the timely application of HMV. The choice between invasive and noninvasive HMV should be based on the patient's age and NIV trial tolerance. Systematic follow-up guidelines provided by a multidisciplinary team are needed.

    Subclinical rejection (SCR) has been variably associated with reduced graft survival, development and progression of interstitial fibrosis/tubular atrophy and chronic allograft nephropathy, but data are controversial concerning SCR treatment in terms of graft survival improvement. In this single-center retrospective study, we enrolled 174 adult kidney transplant recipients with a protocol biopsy performed at 30 days after transplantation to evaluate the incidence rate and risk factors for early SCR and its impact on 10-year graft survival. Five patients showed primary non function and were excluded. Among 159/169 (94.08 %) patients with stable graft function who underwent protocol biopsy, 17 (10.7 %) showed signs of SCR and were treated with low-dose intravenous (i.v.) steroids. Ten patients showed functional impairment, 8 (4.73 %) resulting as acute rejection. At multivariate analysis, donor age [odds ratio (OR) 1.04, 95 % confidence interval (CI) 1.01-1.09], and delayed graft function (DGF) (OR 1.08, 95 % CI 1.03-1.12) were significantly associated with SCR. The 10-year graft survival rate in the SCR group was similar to that in the normal-findings group (76.5 vs. 74.9 % respectively; p = 0.61). At multivariate Cox regression, acute [hazard ratio (HR) 5.22, 95 % CI 1.70-16.01], but not sub-clinical, rejection was independently associated with long-term graft failure. In conclusion, early protocol biopsy is a useful and safe tool to detect early SCR which seems not to affect the long-term survival. We suggest that this could be, probably, linked to early SCR treatment with low dose i.v. steroids. PMID:25966801

    Full Text Available Background: The cornerstones of successful treatment of hepatoblastoma (HB include preoperative chemotherapy followed by complete anatomical resection of tumor, followed by chemotherapy. Advances in chemotherapy in the last 2 decades have been associated with a higher rate of tumor response and possibly a greater potential for resectability. Aims: We analyzed our single center experience with neoadjuvant chemotherapy (NACT and surgery in HBs. Settings and Design: Our study included all children with HBs who received NACT and underwent surgical excision from January 1997 to July 2004. Materials and Methods: Patient characteristics, clinical features, clinical course, treatment modalities, and long-term outcome were analyzed. Results: There were 9 boys and 3 girls, aged 5-60 months (median age at tumor diagnosis was 24 months. All received NACT containing cisplatin and doxorubicin. Of the 12 children, 9 underwent hepatectomy and among them, 4 patients each had right and left hepatectomy and 1 patient underwent right extended hepatectomy. After surgery, all patients completed rest of the chemotherapy course (total 6 cycles. R0 resection was carried out in all the 9 cases with no life-threatening complications. Conclusions: Our experience of the 9 cases, although less in number, reaffirms the advantages of NACT followed by surgery. The prognosis for patients with resectable tumors is fairly good in combination with chemotherapy.

    Full Text Available Objective: To analyze trends in screening and invasive prenatal diagnosis of chromosome abnormalities (CA over a 13-year period and correlate them to changes in the national prenatal screening policy. Methods: We retrospectively reviewed Down syndrome (DS screening tests and fetal karyotypes obtained by prenatal invasive testing (IT in our fetal medicine unit between January 1999 and December 2011. Results: A total of 24,226 prenatal screening tests for DS and 11,045 invasive procedures have been analyzed. Over a 13-year period, utilization of non-invasive screening methods has significantly increased from 57% to 89%. The percentage of invasive procedures has declined from 49% to 12%, although the percentage of IT performed for maternal anxiety has increased from 22% to 55%. The percentage of detected CA increased from 2.5% to 5.9%. Overall, 31 invasive procedures are needed to diagnose 1 abnormal case, being 23 procedures in medical indications and 241 procedures in non-medical indications. Conclusions: Our experience on screening and invasive prenatal diagnostic practice shows a decrease of the number of IT, with a parallel decline in medical indications. There is an increasing efficiency of prenatal screening program to detect CA. Despite the increasing screening policies, our population shows a growing request for prenatal IT. The a priori low risk population shows a not negligible residual risk for relevant CA. This observation challenges the current prenatal screening strategy focused on DS; showing that the residual risk is higher than the current cut-off used to indicate an invasive technique.

Pediatr Transplantation 2011: 15:240-244. © 2009 John Wiley & Sons A\\/S. Abstract:  We assessed our long-term experience with regards to the safety and efficacy of MMF in our pediatric renal transplant population and compared it retrospectively to our previous non-MMF immunosuppressive regimen. Forty-seven pediatric renal transplants received MMF as part of their immunosuppressive protocol in the period from January 1997 till October 2006 (MMF group). A previously reported non-MMF group of 59 pediatric renal transplants was included for comparative analysis (non-MMF group). The MMF group comprised 29 boys and 18 girls, whereas the non-MMF group comprised 34 boys and 25 girls. Mean age was 11.7 and 12 yr in the MMF and non-MMF groups, respectively. The incidence of acute rejection episodes was 11 (23.4%) and 14 (24%) in the MMF and non-MMF group, respectively. Two (3.3%) grafts were lost in the non-MMF group compared with one (2.1%) in the MMF group. Twenty-one (44.68%) patients in the MMF group developed post-transplant infections compared with 12 (20.33%) in the non-MMF group (p < 0.0001). In conclusion, the use of MMF in pediatric renal transplantation was not associated with a lower rejection rate or immunological graft loss. It did, however, result in a significantly higher rate of viral infections.

    Full Text Available BACKGROUND: Percutaneous pulmonary valvuloplasty is well established treatment of choice in pulmonary valve stenosis. AIM: The aim of our study was to present our experience with the interventional technique, its immediate and mid-term effectiveness as well as its complication rate. MATERIAL AND METHODS: The study included 43 patients, where 33 (74% of them were children between the age of 1 month and 15 years. RESULTS: The procedure was successful in 38 patients or 90%. Mean peak to peak transvalvular gradient was reduced from 91.2 mmHg (55-150 mmHg to 39.1 mmHg (20-80 mmHg. Follow- up of patients was between 2 and 13 years and included echocardiographic evaluation of pulmonary valve gradient, right heart dimensions and function as well as assessment of pulmonary regurgitation. We experienced one major complication pericardial effusion in a 5 months old child that required pericardiocenthesis. Six patients (13.9% required a second intervention. During the follow up period there was significant improvement of right heart function and echocardiography parameters. Mild pulmonary regurgitation was noted in 24 (55% patients, and four (9% patients developed moderate regurgitation, without affecting the function of the right ventricle. CONCLUSIONS: Percutaneous pulmonary valvuloplasty is an effective procedure in treatment of pulmonary stenosis with good short and mid-term results.

    Use of organs from marginal donors for transplantation is a current strategy to expand the organ donor pool. Its efficacy is universally accepted among data from multicenter studies. Herein, we have reviewed outcomes of double kidney transplantation (DKT) over an 9-year experience in our center. The aim of this study was to evaluate possible important differences between a monocenter versus multicenter studies. Between 1999 and 2008, we performed 59 DKT. Recipient mean age was 63 +/- 5 years. Mean HLA-A, -B, and -DR mismatches were 3.69 +/- 0.922. Donor mean age was 69 +/- 7 years and mean creatinine clearance was 69.8 +/- 30.8 mL/min. Proteinuria was detected in three donors (5%). Mean cold ischemia and warm ischemia times were 1130 +/- 216 and 48 +/- 11 minutes, respectively. The right and left kidney scores were 4.18 +/- 2 and 4.21 +/- 2, respectively. Thirty patients (51%) displayed good postoperative renal function; 22 (37%), acute tubular necrosis with postoperative dialysis; 3 (5%), acute rejection episodes; 4 (7%), single-graft transplantectomy due to vascular thrombosis; 1 (2%), a retransplantation; 5 (8%), a lymphocele; 3 (5%) vescicoureteral reflux or stenosis requiring surgical correction. Cytomegalovirus infection was detected in five patients (8%). In three patients (5%) displayed de novo neoplasia. Three patients showed chronic rejection (5%), whereas we observed a cyclosporine-related toxicity in 7 (12%). Nine patients (15%) developed iatrogenic diabetes. Patient and graft survivals after 3 years from DKT were 93% and 86.3%, respectively. In this study, we applied successfully a widespread score to allocate organs to single kidney transplantation or DKT. In our experience, the score is suitable for the organ allocation but it may be overprotective, excluding potentially suitable organs for a single transplantation. PMID:20534235

    Capsule endoscopy (CE) is a novel technology that facilitates highly effective and noninvasive imaging of the small bowel. Although its efficacy in the evaluation of obscure gastrointestinal bleeding (OGIB) has been proven in several trials, data on uses of CE in different small bowel diseases are rapidly accumulating in the literature, and it has been found to be superior to alternative diagnostic tools in a range of such diseases.Based on literature evidence, CE is recommended as a first-line investigation for OGIB after negative bidirectional endoscopy. CE has gained an important role in the diagnosis and follow-up of Crohn's disease and celiac disease and in the surveillance of small bowel tumors and polyps in selected patients. Capsule retention is the major complication, with a frequency of 1%-2%. The purpose of this review was to discuss the procedure, indications, contraindications and adverse effects associated with CE. We also review and share our five-year experience with CE in various small bowel diseases. The recently developed balloon-assisted enteroscopies have both diagnostic and therapeutic capability. At the present time, CE and balloon-assisted enteroscopies are complementary techniques in the diagnosis and management of small bowel diseases.

    Objective Treatment of intracranial dural arteriovenous fistulas (dAVFs) remains a challenge. However, after introduction of Onyx, transarterial approach is the preferred treatment option in many centers. We report our experience of dAVFs embolization with special emphasis on transarterial approach. Methods Seventeen embolization procedures were performed in 13 patients with dAVFs between Jan 2009 and Oct 2014. Clinical symptoms, location and type of fistulas, embolization methods, complications, radiological and clinical outcomes were evaluated using charts and PACS images. Results All 13 patients had symptomatic lesions. The locations of fistulas were transverse-sigmoid sinus in 6, middle fossa dura in 4, cavernous sinus in 2, and superior sagittal sinus in 1 patient. Cognard types were as follows : I in 4, IIa in 2, IIa+IIb in 5, and IV in 2. Embolization procedures were performed ≥2 times in 3 patients. Nine patients were treated with transarterial Onyx embolization alone. One of these required direct surgical puncture of middle meningeal artery. Complete obliteration of fistulas was achieved in 11/13 (85%) patients. There were no complications except for 1 case of Onyx migration in cavernous dAVF. Modified Rankin scale score at post-operative 3 months were 0 in 11, and 3 in 2 patients. Conclusion Transarterial Onyx embolization can be a first line therapeutic option in patients with dAVFs. However, transvenous approach should be tried first in cavernous sinus dAVF because of the risk of intracranial migration of liquid embolic materials. Furthermore, combined surgical endovascular approach can be considered as a useful option in inaccessible route. PMID:26885282

    Full Text Available Renal transplantation (RTx is considered as the best therapeutic modality for patient suffering from end-stage renal disease (ESRD. Dearth of donor kidneys is a major problem everywhere, and deceased donor renal transplantation (DDRTx is seen as at least a partial solution. Even so, DDRTx accounts for only less than 4% of RTx in India. We report our 6-year single-center experience on DDRTx vis-à-vis patient/graft survival, graft function in terms of serum creatinine (SCr, rejection episodes, and delayed graft function (DGF. Between January 2005 and March 2011, 236 DDRTx were performed. Majority of the donors were those with brain death due to road traffic/cerebrovascular accidents. The commonest recipient diseases leading to ESRD were chronic glomerulonephritis (42.8%, diabetes (12.7%, and hypertension (10.6%. Mean recipient age was 36.2 ± 14.2 years; 162 were males and 74 were females. Mean donor age was 45.3 ± 17.13 years; 144 were males and 92 were females. Mean dialysis duration pre-transplantation was 18.5 ± 2.5 months. All recipients received single-dose rabbit-anti-thymocyte globulin induction and steroids, calcinueurin inhibitor, and mycophenolate mofetil/azathioprine for maintenance immunosuppression. Delayed graft function was observed in 29.6% patients and 22% had biopsy-proven acute rejection. Over the mean follow-up of 2.18 ± 1.75 years, patient and graft survival rates were 74.57% and 86.8%, respectively, with mean SCr of 1.42 ± 0.66 mg%. DDRTx achieves acceptable graft function with patient/graft survival, encouraging the use of this approach in view of organ shortage.

    Post-transplant lymphoproliferative disorder is a serious complication of solid organ transplantation; however, few large studies have been performed in Asian institutions. We review our single-center experience with post-transplant lymphoproliferative disorder patients in Japan. We retrospectively evaluated patients with post-transplant lymphoproliferative disorder following kidney transplantation between January 1985 and December 2013. The patients were divided into early-onset post-transplant lymphoproliferative disorder ( 10 years after transplantation; therefore, long-term monitoring of patients is needed. PMID:26948427

    Dofasco's No. 4 blast furnace was retrofitted with a bell-less top in 1980 after nine years of operation using a 2-bell top. During the 1986 rebuild, the bell-less top gearbox cooling was converted from gas to water. The furnace throat diameter was also increased from 7.3 to 8.2 meters. In this presentation, Dofasco's experience using the bell-less top over the last 13 years will be reviewed. Topics to be discussed will include burden distribution with 100% pellets at various levels of tuyere injectants and productivity levels, instrumentation used to optimize distribution, and modeling requirements, as well as maintenance requirements for the top. In addition, the latest developments of the bell-less top system, including the new compact design will be reviewed.

    Background Minimally invasive approach has gained interest in the treatment of patients with colorectal cancer. The purpose of this study is to analyze the differences between laparoscopy and robotics for colorectal cancer in terms of oncologic and clinical outcomes in an initial experience of a single center. Materials and Methods Clinico-pathological data of 100 patients surgically treated for colorectal cancer from March 2008 to April 2014 with laparoscopy and robotics were analyzed. The procedures were right colonic, left colonic, and rectal resections. A comparison between the laparoscopic and robotic resections was made and an analysis of the first and the last procedures in the 2 groups was performed. Results Forty-two patients underwent robotic resection and 58 underwent laparoscopic resection. The postoperative mortality was 1%. The number of harvested lymph nodes was higher in robotics. The conversion rate was 7.1% for robotics and 3.4% for laparoscopy. The operative time was lower in laparoscopy for all the procedures. No differences were found between the first and the last procedures in the 2 groups. Conclusions This initial experience has shown that robotic surgery for the treatment of colorectal adenocarcinoma is a feasible and safe procedure in terms of oncologic and clinical outcomes, although an appropriate learning curve is necessary. Further investigation is needed to demonstrate real advantages of robotics over laparoscopy. PMID:26721500

  1. Pharmacomechanical Thrombolysis for the Treatment of Thrombosed Native Arteriovenous Fistula: A Single-Center Experience

    Native arteriovenous fistula is one of the important routes for hemodialysis patients because of increased long-term survival and preservation of quality of life. We reported on a single-center experience with using pharmacomechanical thrombolysis for the treatment of thrombosed native arteriovenous fistula. This was a retrospective study of 12 hemodialysis patients (8 males and 4 females) with 14 thrombosed distal forearm Brescia-Cimino radiocephalic fistulas who were referred for pharmacomechanical thrombolytic treatment in the intervention unit of the Radiology Department, from 1 January 2010 to 30 December 2011. Demographic data, technical success rates, clinical success rates and complications were evaluated. The patency was evaluated by Kaplan-Meier analysis. The technical and clinical success was found in 12 thrombosed fistulas. Only 3 procedures had minor complications including small amounts of adjacent soft tissue hematoma. There were no procedure-related major complications. The primary patency rates at 6 and 12 months were 67% and 50%. The secondary patency rates at 6 and 12 months were 75% and 67%. Pharmacomechanical thrombolysis is a minimally invasive, effective, durable, and safe procedure for the treatment of thrombosed native arteriovenous fistula. This procedure can be considered as an alternative treatment for thrombosed dialysis fistulas

    Background Carotid artery stenting (CAS) as a competing treatment modality has had to adhere to limits to gain widespread acceptance in some studies.This study analyzed the clinical data of 1700 consecutive patients after CAS to retrospectively evaluate the 30-day outcome of CAS for internal carotid artery stenosis in a Chinese population.Methods Medical records of 1700 patients who underwent CAS at Xuanwu Hospital affiliated to Capital Medical University between January 2001 and August 2012 were reviewed.Postoperative 30-day complication rates were analyzed and compared with those of other studies.Univariate and multivariate Logistic regression analyses were used to identify factors associated with perioperation myocardial infarction (MI),stroke,and death.Results The overall 30-day rate of MI,stroke,and death after CAS was 2.53%.In univariate analysis,patients who were symptomatic,had a neurological deficit (modified Rankin score (mRS) ≥3; P=0.001),and who were not taking statins experienced a significantly increased rate of MI,stroke,and death (P=-0.017).In multivariate Logistic regression analysis,the presence of symptoms (odds ratio (OR)=2.485; 95% confidence interval (CI)=1.267-4.876; P=0.008) and a neurological deficit (mRS ≥3) (OR=3.025; 95% CI=1.353-6.763; P=0.007) were independent risk factors for perioperative MI,stroke,and death.Conclusions According to this single-center experience,CAS may effectively prevent and treat carotid artery stenosis that would otherwise lead to stroke.Being symptomatic and having a neurological deficit (mRS ≥3) increased the risk of perioperative MI,stroke,and death.

  4. Acute promyelocytic leukemia, study of predictive factors for Differentiation Syndrome, single center experience

    Reports about patients with acute promyelocytic leukemia from the Middle East are few; in this study we are reporting our single center experience of treating 29 patients over 6 years. Acute promyelocytic leukemia treatment response is markedly improved after the introduction of ATRA. Treatment related complication is still an important issue particularly Differentiation Syndrome. Prediction to its occurrence has been tried by other groups. We aimed to study all the possible predictive factors of acute promyelocytic leukemia. Our chemotherapy induction protocol is AIDA protocol which includes ATRA 45 mg/m2/d in divided doses every 12h, and Idarubicin 12 mg/ m2/d IV on days 3, 5, 7, and 9. Differentiation Syndrome occurred in 48.3% of patients and was mainly presented by pulmonary symptoms in 55.2%, 6 cases died during induction. None of the predictive factors studied showed a statistically significant difference between patients who developed Differentiation Syndrome and those who did not. Differentiation Syndrome did not affect overall survival. Cox regression showed an inverse yet a non significant association between PET- HEMA and overall survival probability (P = 0.168). In conclusion, Differentiation Syndrome has no clear predictive factor to date. The best approach is to hold ATRA and give dexamethasone which is quite effective as reported in the literature. PETHEMA risk model has a moderately significant prognostic value look for all possible predictive factors of Differentiation syndrome (DS) which were first described in 1992 by frankel et al. (4) and represented the major complication through this disease course: studies had reported conflicting results about this (5,6). In addition we will compare our data to other areas of the world

    Full Text Available Purpose: To present a single-center experience with 25 cases of bronchopulmonary malformations and the review the literature. Materials and Methods: We conducted a retrospective analysis of the medical records of patients with congenital bronchopulmonary malformations who were operated between July 1997 and July 2007 in our institute; we examined the modes of presentations, management, and outcome. Outcome of all patients was assessed over a short follow-up period (average 1.8 months. Results: Out of 25 patients, 18 (72% were male and 7 (28% were female. Age of patients ranged from 1 day to 11 years. The histopathological diagnosis was congenital cystic adenomatoid malformations [CCAM; n = 14 (56%], congenital lobar emphysema [CLE; n = 5 (20%], pulmonary sequestrations [PS; n = 3 (12%], and bronchogenic cysts [BC; n = 3 (12%]. Antenatal diagnosis was available in only 2 (8% patients. The common presenting symptoms were respiratory distress and chest infections. Lobectomy was the procedure of choice . Mortality was 16% (n = 4; M: F = 3: 1. Two patients died because of overwhelming sepsis, one from compromised cardiac function, and one from aspiration which might possibly have been prevented. Conclusion: Patients with progressive respiratory distress due to these anomalies may require urgent surgical intervention regardless of age. The surgical outcome is favorable, with manageable complications. Plain x-ray chest and CT of thorax are usually sufficient for diagnosis and planning of treatment. Pathological diagnosis may differ from the imaging diagnosis. Mortality is found to be more in neonates. Apart from initial stabilization, resection of lesion and careful postoperative care is necessary to reduce mortality and morbidity.

    Full Text Available The aim of this study is to report the experience from a single center in Libya, on the prevailing live-related kidney transplantation program. The results of three years work on kidney transplantation at the Tripoli Central Hospital (National Organ Transplant Program in Libya were evaluated. The transplant program was launched on 17 th August, 2004 and 135 patients have been transplanted since then till 17 th August, 2007. All donors and recipients were screened thoroughly prior to transplant and monitored closely in the post-transplant period. Our immuno-suppressive protocol was cyclosporine-based. Among the 135 accepted pairs, donors and reci-pients were genetically-related in 133 cases (98.5% and emotionally-related in two others. The mean donor age was 37 ± 9.5 years (range 18-56 years and recipient age 37 ± 13.6 years (range 7-67 years. There were 95 males (70.4% and 40 females (29.6% among the recipients while among the donors, there were 102 males (75.6% and 33 females (24.4%. Delayed graft function was seen in three patients (2.2%, acute rejection in six (4.4%, post-transplant urinary tract infection in six (4.4%, pneumonia in three (2.2%, ureteric kink in two (1.5% and urine leak in four (3.0%. Graft survival at 36 months was 93.3% while patient survival at the same period was 96.3%. This report indicates that the results of our transplant program are good and comparable with other international programs.

    Full Text Available Background. This is a single center oncological resume overlooking four decades of experience with liver transplantation (LT for hepatocellular carcinoma (HCC. Methods. All 319 LT for HCC that were performed between 1975 and 2011 were included. Predictors for HCC recurrence (HCCR and survival were identified by Cox regression, Kaplan-Meier analysis, Log Rank, and χ2-tests where appropriate. Results. HCCR was the single strongest hazard for survival (exp⁡B=10.156. Hazards for HCCR were tumor staging beyond the histologic MILAN (exp⁡B=3.645, bilateral tumor spreading (exp⁡B=14.505, tumor grading beyond G2 (exp⁡B=8.668, and vascular infiltration of small or large vessels (exp⁡B=11.612, exp⁡B=18.324, resp.. Grading beyond G2 (exp⁡B=10.498 as well as small and large vascular infiltrations (exp⁡B=13.337, exp⁡B=16.737, resp. was associated with higher hazard ratios for long-term survival as compared to liver transplantation beyond histological MILAN (exp⁡B=4.533. Tumor dedifferentiation significantly correlated with vascular infiltration (χ2p=0.006 and intrahepatic tumor spreading (χ2p=0.016. Conclusion. LT enables survival from HCC. HCC dedifferentiation is associated with vascular infiltration and intrahepatic tumor spreading and is a strong hazard for HCCR and survival. Pretransplant tumor staging should include grading by biopsy, because grading is a reliable and easily accessible predictor of HCCR and survival. Detection of dedifferentiation should speed up the allocation process.

Methods: A total of 131 patients with symptomatic degenerative disc disease refractory to nonsurgical treatment were treated with AxiaLIF at L5–S1, and were followed for a minimum of 1 year (mean: 21 months. Main outcomes included back and leg pain severity, Oswestry Disability Index score, working status, analgesic medication use, patient satisfaction, and complications. Computed tomography was used to determine postoperative fusion status. Results: No intraoperative complications, including vascular, neural, urologic, or bowel injuries, were reported. Back and leg pain severity decreased by 51% and 42%, respectively, during the follow-up period (both P < 0.001. Back function scores improved 50% compared to baseline. Clinical success, defined as improvement ≥30%, was 67% for back pain severity, 65% for leg pain severity, and 71% for back function. The employment rate increased from 47% before surgery to 64% at final follow-up (P < 0.001. Less than one in four patients regularly used analgesic medications postsurgery. Patient satisfaction with the AxiaLIF procedure was 83%. The fusion rate was 87.8% at final follow-up. During follow-up, 17 (13.0% patients underwent 18 reoperations on the lumbar spine, including pedicle screw fixation (n = 10, total disc replacement of an uninvolved level (n = 3, facet screw fixation (n = 3, facet screw removal (n = 1, and interbody fusion at L4–L5 (n = 1. Eight (6.1% reoperations were at the index level. Conclusion: Single-level AxiaLIF is a safe and effective means to achieve lumbosacral fusion in patients with symptomatic degenerative disc disease.

  12. Aggressive Treatment of Patients with Metastatic Colorectal Cancer Increases Survival: A Scandinavian Single-Center Experience

    Kristoffer Watten Brudvik

    2013-01-01

    Full Text Available Background. We examined overall and disease-free survivals in a cohort of patients subjected to resection of liver metastasis from colorectal cancer (CRLM in a 10-year period when new treatment strategies were implemented. Methods. Data from 239 consecutive patients selected for liver resection of CRLM during the period from 2002 to 2011 at a single center were used to estimate overall and disease-free survival. The results were assessed against new treatment strategies and established risk factors. Results. The 5-year cumulative overall and disease-free survivals were 46 and 24%. The overall survival was the same after reresection, independently of the number of prior resections and irrespectively of the location of the recurrent disease. The time intervals between each recurrence were similar (11 ± 1 months. Patients with high tumor load given neoadjuvant chemotherapy had comparable survival to those with less extensive disease without neoadjuvant chemotherapy. Positive resection margin or resectable extrahepatic disease did not affect overall survival. Conclusion. Our data support that one still, and perhaps to an even greater extent, should seek an aggressive therapeutic strategy to achieve resectable status for recurrent hepatic and extrahepatic metastases. The data should be viewed in the context of recent advances in the understanding of cancer biology and the metastatic process.

  13. Exclusion Reasons of Living Kidney Donor Candidates: A Single-Center Experience

    Ayşegül ORUÇ

    2014-05-01

    Full Text Available OBJECTIVE: Due to severe organ shortage, living kidney donors are important choices for transplantation. In Muslim countries, such as Turkey, living kidney donors are the main source of donor pool. In the literature, reasons for living donor exclusion are reported from several countries. However, there is no published study that focused on exclusion reasons of donor candidates in Turkey where living kidney transplantation rate is 73.4%. The goal of this retrospective study was to examine the exclusion reasons for donation among living kidney donor candidates at a single center in Turkey. MATERIAL and METHODS: A total 538 adults were evaluated as a living kidney donor candidate between December 1988 and January 2012. Evaluation outcome, exclusion reasons and demographic data were examined from electronic file system and immunology laboratory records. RESULTS: In this period 451 kidney transplantations (38.6% cadaveric, 61.4% living donor was performed. Overall 261 (48.5% donor candidates who underwent evaluation could not donate. We were able to find the precise cause of exclusion of 86 donors (33%. Among excluded donor candidates the most common exclusion reason was medical causes (64% such as diabetes mellitus, low glomerular filtration rate and hypertension. CONCLUSION: Our study suggests that medical causes are significant exclusion reasons for living kidney donation at our center.

    Full Text Available Background : 5-Flourouracil (FU-based chemotherapy (CT and concurrent 45 Gy radiotherapy (RT is one of the standard postoperative approaches currently used in gastric carcinoma. The high toxicity rates of this treatment leads to interruption of treatment in the majority of patients. In our study, we investigated the rates of toxicity and treatment discontinuation observed during postoperative FU-based chemoradiotherapy (CRT; retrospectively evaluated the effect of CRT and the other prognostic factors on local and distant control and survival. Patients and Methods: A total of 160 patients consisting of 97 total and 63 subtotal gastrectomy receiving postoperative CRT, have been studied retrospectively. Results : Patients who had to discontinue the treatment for a median of 6 (range, 3-13 days experienced toxicity during treatment at a rate of 43%. During the 21 (range, 4-68 months of follow-up local recurrences were observed in 8 (5% patients and distant recurrences were observed in 41 (25.6% patients. While the 1-3 year overall survival (OS rates were 75% and 42%, 13-year disease-free survival (DFS rates were 63% and 42%, respectively. In the univariate analysis for OS and DFS demonstrated statistical significance for below those 60 years of age, D1-D2 dissection type, negative surgical margin, early treatment beginning, the absence of invasion, and early stage disease. D1D2 dissection type, early treatment begining, age below 60 years and early stage disease significantly improve OS and DFS in multivarite analysis. Conclusions: Survival is worse in patients older than 60 years, had late treatment begining, advanced stage and D0 dissection.

    To analyze the outcome of patients undergoing percutaneous CT-guided radiofrequency ablation (RFA) of small renal masses (SRM) at a single center during a ten-year time period. Patient records of renal RFAs (07/2003 - 11/2013) were reviewed. Indications were SRM suspicious of malignancy on imaging and one of the following: severe comorbidity; old age; solitary kidney; impaired renal function; patient wish. Biopsy was performed at the time of RFA. Patients were excluded if no follow-up was available. Patient and procedural characteristics were recorded. Survival rates were calculated using the Kaplan-Meier's method and compared with log-rank or cox tests. 38 patients (16 females, mean age 70.0 years [range 52 - 87]) presenting with a solitary SRM were included in the study. Biopsy showed malignancy in 29 patients; 9 had benign tumors. 26 patients suffered from cardiovascular, respiratory or hepatic comorbidities. Technical success (complete ablation on first follow-up) was achieved in 95 % of cases. Two major complications (bowel perforation; hematothorax) occurred. The 3- and 7-year overall survival (OS) [any cause] rates were 73.4 ± 0.8 % and 50.3 ± 1.0 %, respectively (mean follow-up 54.6 months, range 1 - 127). 4 recurrences and 2 metastases were observed. The presence of comorbidities was the only independent predictor of OS. There was no difference in survival between patients with benign and malignant tumors. RFA of SRM is successful in a large percentage of cases with a low complication rate and durable local control. As RFA is typically performed in multimorbid patients, overall survival seems to depend primarily on comorbidities rather than cancer progression.

    Myelofibrosis (MF) is a rare disease responsible for an increasing ineffective hematopoesis by a progressive fibrosing process in the bone marrow. The only curative treatment option is allogeneic hematopoietic cell transplantation (HCT). In this single-center analysis, we evaluated retrospectively 54 consecutive patients suffering from primary or secondary MF which underwent HCT from 1997 to 2014 after either myeloablative (MAC, n = 19) or reduced-intensity conditioning (RIC, n = 35). Overall survival (OS) and disease-free survival (DFS) after 3 years was 54/53 % for RIC versus 63/58 % for MAC (p = 0.8/0.97). Cumulative incidence of relapse was 34 % after RIC and 8 % after MAC (p = 0.16). Three-year non-relapse mortality (NRM) was 15 % after RIC and 34 % after MAC (p = 0.29). We found that RIC was associated with a lower incidence of acute graft versus host disease (GvHD; II-IV 26 vs. 0 %, p = 0.004). Evaluation of prognostic relevance of the Dynamic International Prognostic Scoring System (DIPSS) score showed a significant better OS in patient with risk score ≤3 versus >3 (after 3 years, 71 vs. 39 %, p = 0.008). While similar OS and DFS were observed with MAC or RIC, the use of RIC resulted in lower incidence of acute GvHD. RIC regimens may be therefore the preferred conditioning approach for allogeneic HCT in patients with MF. PMID:27021303

    The aim of this study was to assess the clinical sensitivities of the tumor markers chromogranin A (CgA), urinary 5-hydroxyindoleacetic acid (5-HIAA) and alkaline phosphatase (AP) in neuroendocrine tumors (NETs) of the GastroEnteroPancreatic-(GEP-) system depending on tumor primary location and metastatic spread. In a retrospective single-center series, sensitivities were evaluated in serum samples from 110 patients with midgut (n = 62) and pancreatic (n = 48) NETs. CgA levels were analyzed by a commercially-available immunoradiometric assay (CIS-bio) during routine follow-up in the years 2000–2009. CgA showed a higher sensitivity for midgut (68%) than pancreatic (54%) NETs. A higher CgA sensitivity and significantly higher median CgA values were found in patients with liver metastases than in those without, and in patients with hepatic and additionally extra-hepatic metastases than in those with hepatic and nodal metastases alone, respectively. We found an overall sensitivity for elevated 5HIAA excretion of 69% for midgut NETs and a significant correlation between median CgA and 5-HIAA values. The sensitivity of AP and the correlations of AP/CgA-data-pairs were low in both midgut and pancreatic NETs, although highest for metastatic pancreatic NETs. The sensitivity of CgA measurement depends on the NET primary location and spread of disease. 5-HIAA and CgA showed comparable sensitivity in midgut NETs, while AP does not seem to be useful as a tumor marker in GEP-NETs.

    PurposeCarotid endarterectomy and stenting are used to treat carotid stenosis, with the volume of carotid artery procedures increasing over the past decade. We investigated the 10-year trend of periprocedural complications with an increasing procedure volume of carotid stenting at a single tertiary hospital.MethodsWe collected 416 consecutive cases (384 patients) of carotid artery stenting performed for either symptomatic (231 cases, 55.5 %) or asymptomatic (185 cases, 44.5 %) internal carotid artery stenosis at a single center. Periprocedural complication was defined as any stroke, myocardial infarction, or death. Procedure-related outcome included any dissection, hemodynamic event, or periprocedural complication.ResultsThe mean age was 68.8 years (82.8 % males; range of 20–89 years); 23.9 % were older than 75 years. Before the procedure, 99.3 and 56.0 % of patients received antiplatelet and lipid-lowering medication, respectively. The overall periprocedural complication rate was 3.6 % (1.6 and 5.2 % in the asymptomatic and symptomatic group, respectively). The composite outcome of any stroke or death was 3.4 %. Periprocedural complication and procedure-related outcome showed a decremental trend with increasing procedure volume, and this trend remained after adjusting for confounders.ConclusionsOur study suggests that carotid stenting at an experienced center might reduce the periprocedural complications. Our periprocedural complication rate of carotid artery stenting may be comparable to, or somewhat lower than, that reported in other clinical trials.

  19. A single-center experience in radioembolization as salvage therapy of hepatic metastases of uveal melanoma

    Overall survival (OS) of patients with hepatic metastases of uveal melanoma is strongly linked with hepatic tumor control. Due to the lack of an effective systemic chemotherapy, locoregional therapies like radioembolization should play an increasingly important role. To report complications and response rates of radioembolization as salvage therapy for hepatic uveal melanoma metastases. Between October 2006 and January 2014, eight patients (age, 59.1 ± 15.3 years; 5 men) with histologically proven uveal melanoma and hepatic metastases received radioembolization with glass microspheres at a single center. All patients had been heavily pretreated with multiple systemic/locoregional therapies resulting in a long median interval between diagnosis of hepatic metastases and radioembolization (17.1 months; range, 6.4–23.2 months). Follow-up consisted of clinical assessment, laboratory tests and tri-phasic computed tomography (CT) before and 1, 3, 6, 9, and 12 months after radioembolization. Response to therapy was evaluated by CT using RECIST version 1.1 and by survival time. Safety (laboratory and clinical toxicity) was rated according to Common Terminology Criteria for Adverse Events 4.03. Using Kaplan-Meier analysis time to progression of hepatic metastases (hTTP) and OS were calculated. One month after radioembolization 50% of patients presented with stable and 50% with progressive disease. Median hTTP and OS after radioembolization were 4.3 weeks (range, 3.4–28.6 weeks) and 12.3 weeks (range, 3.7–62.6 weeks), respectively. Median OS after diagnosis of hepatic metastases was 19.9 months (range, 7.3–31.4 months). Radioembolization was tolerated well in all patients without toxicity higher than grade 2. Radioembolization is a safe salvage therapy even in heavily pretreated hepatic metastases of uveal melanoma

    Neonates born to mothers with immune thrombocytopenic purpura (ITP) have an increased risk of having thrombocytopenia and bleeding. The aim of our study was to determine maternal and fetal factors that can predict bleeding risk in neonates born to mothers with ITP, and effective treatment strategies by retrospective analysis of our single-center data. We performed a retrospective data review of neonates that were recorded as 'neonates born to mothers with ITP' in the Neonatal ICU of Hacettepe University, Ihsan Dogramacı Children's Hospital, Ankara, Turkey. Medical records of 36 neonates born from 35 mothers were analyzed. Among the 36 neonates born to mothers with ITP, thrombocytopenia (platelet count of less than 150 × 10/l) was detected in 20 (56.0%) neonates on the first day of life. Twelve of the 20 neonates with thrombocytopenia (60.0%) required treatment to increase the platelet counts. Clinical findings related to thrombocytopenia occurred in three (15.0%) neonates, but none of them presented with severe bleeding. There was no statistically significant association between neonatal lowest platelet count and maternal lowest platelet count, maternal platelet count at the time of delivery, and duration of thrombocytopenia, respectively. Neonates born to mothers with ITP have an increased tendency to develop thrombocytopenia, but severe bleeding is very rare in these neonates. Clinicians should pay special attention to follow these neonates. According to our results, both intravenous immunoglobulin and methyl prednisolone were found to be in equivalent efficacy for the treatment of neonatal thrombocytopenia due to maternal ITP.

  1. Long-term safety and outcome of a temporary self-expanding metallic stent for achalasia: a prospective study with a 13-year single-center experience

    To prospectively evaluate the long-term clinical safety and efficacy of a newly designed self-expanding metallic stent (SEMS) in the treatment of patients with achalasia. Seventy-five patients with achalasia were treated with a temporary SEMS with a 30-mm diameter. The SEMSs were placed under fluoroscopic guidance and removed by gastroscopy 4-5 days after stent placement. Follow-up data focused on dysphagia score, technique and clinical success, clinical remissions and failures, and complications and was performed at 6 months, 1 year, and within 3 to 5 years, 5 to 8 years, 8 to 10 years, and >10 years postoperatively. Stent placement was technically successful in all patients. Complications included stent migration (n=4, 5.33%), chest pain (n=28, 38.7%), reflux (n=15, 20%), and bleeding (n=9, 12%). No perforation or 30-day mortality occurred. Clinical success was achieved in all patients 1 month after stent removal. The overall remission rates at 6 months, 1, 1-3, 3-5, 5-8, 8-10, and >10 year follow-up periods were 100%, 96%, 93.9%, 90.9%, 100%, 100%, and 83.3%, respectively. Stent treatment failed in six patients, and the overall remission rate in our series was 92%. The median and mean primary patencies were 2.8 ± 0.28 years (95% CI: 2.25-3.35) and 4.28 ± 0.40 years (95% CI: 3.51-5.05), respectively. The use of temporary SEMSs with 30-mm diameter proved to be a safe and effective approach for managing achalasia with a long-term satisfactory clinical remission rate. (orig.)

    To assess patient radiation doses during cerebral angiography and embolization of intracranial aneurysms in a large sample size from a single center. We studied a sample of 439 diagnostic and 149 therapeutic procedures for intracranial aneurysms in 480 patients (331 females, 149 males; median age, 57 years; range, 21-88 years), which were performed in 2012 with a biplane unit. Parameters including fluoroscopic time, dose-area product (DAP), and total angiographic image frames were obtained and analyzed. Mean fluoroscopic time, total mean DAP, and total image frames were 12.6 minutes, 136.6 +/- 44.8 Gy-cm{sup 2}, and 251 +/- 49 frames for diagnostic procedures, 52.9 minutes, 226.0 +/- 129.2 Gy-cm{sup 2}, and 241 frames for therapeutic procedures, and 52.2 minutes, 334.5 +/- 184.6 Gy-cm{sup 2}, and 408 frames for when both procedures were performed during the same session. The third quartiles for diagnostic reference levels (DRLs) were 14.0, 61.1, and 66.1 minutes for fluoroscopy time, 154.2, 272.8, and 393.8 Gy-cm{sup 2} for DAP, and 272, 276, and 535 for numbers of image frames in diagnostic, therapeutic, and both procedures in the same session, respectively. The proportions of fluoroscopy in DAP for the procedures were 11.4%, 50.5%, and 36.1%, respectively, for the three groups. The mean DAP for each 3-dimensional rotational angiographic acquisition was 19.2 +/- 3.2 Gy-cm{sup 2}. On average, rotational angiography was used 1.4 +/- 0.6 times/session (range, 1-4; n = 580). Radiation dose in our study as measured by DAP, fluoroscopy time and image frames did not differ significantly from other reported DRL studies for cerebral angiography, and DAP was lower with fewer angiographic image frames for embolization. A national registry of radiation-dose data is a necessary next step to refine the dose reference level.

    Full Text Available Objectives: A thyroglossal duct cyst (TDC is a frequent congenital midline anomaly of the neck that usually manifests during the first decade of life. We aimed to describe the presentation, management, and outcome of TDC in pediatric and adult cases. Methods: A retrospective observational analysis was conducted for all patients diagnosed and treated for TDC between 2000 and 2014 in a single center in Qatar. Data included patients’ demographics, presentations, preoperative investigations, anesthesia type, histopathological findings, surgical management, recurrences, and complications. Results: We identified 102 patients, of which 57% were males. The mean age of patients was 20.2±15.6 years. A bimodal distribution of TDC has been observed, which peaked between the ages of 6–13 years and at ≥19 years. The preoperative evaluation mainly includes ultrasonography (66%, thyroid function test (44%, and fine-needle aspiration cytology (10%. The median size of the cyst was 25 (2–60 mm. Patients mainly presented with an asymptomatic midline neck mass at or below the hyoid bone (82%, followed by fistula (9%, infection (2%, and dysphagia (2%. Eighty-nine cases were identified preoperatively as TDC. The histopathological findings confirmed TDC with hyoid bone in 61 cases, and TDC alone in 38 cases. Eighty patients underwent the Sistrunk procedure while excision of TDC alone was observed in 18 cases. Five cases of recurrent disease were also treated. Adults had a greater median cyst size (30 (9–60 vs. 22 (2–55 mm; p = 0.005 and required prolonged operation time (69 (1–169 vs. 32.5 (1–140 mins; p = 0.004 compared to the pediatric group. Conclusion: The occurrence of TDC shows a bimodal age distribution. Preoperative evaluation and time for surgery vary whereas clinical presentations, surgical management, and postoperative outcomes are comparable among adult and pediatric groups. Ultrasonography is the preferred diagnostic modality, and the

    Basilar artery dissection is a rare disease with high morbidity and mortality. No well-established management strategy exists for this lesion. Endovascular reconstructive therapy using stents (with or without coiling) may be the optimum strategy.We describe our center's experience for this treatment strategy in 21 patients with basilar artery dissection from January 2009 to July 2014 (17 men, four women; age range, 18-70 years; median age, 56 years). We divided patients into two groups: Group 1 patients received stent-assisted coiling treatment, and Group 2 patients received stent-only treatment. Pre-treatment, peri-operation and follow-up evaluation were investigated for complications, clinical outcome and angiographic results. The median follow-up time was 20 months (range, 3-67 months).All patients were treated endovascularly by stent-assisted coiling (14 patients) or stent only (seven patients). Immediate angiography showed: in Group 1, five of 14 lesions were completely occluded, five were partially occluded, four revealed retention of contrast media; in Group 2, all patients (seven of seven) had contrast retention. At the follow-up visit (median seven months, 3-29 months), the aneurysms were angiographically improved in five of 13 patients in Group 1 compared with immediately post-operation, while six of sevenimproved in Group 2. Five patients (all in Group 1) had ischemic or hemorrhage peri-operation complications. Long-term good clinical outcomes (modified Rankin Scale score (mRS) ≤ 2) were achieved in all patients except three death cases (two in Group1, one in Group 2).In our experience, endovascular reconstructive therapy using stents (with or without coiling) for basilar artery dissection is effective and safe. Stent-only treatment seems have a better safety profile during the peri-operation period. PMID:26842610

  9. New insights into the clinical evaluation of hereditary transthyretin amyloidosis patients: a single center's experience

    Full Text Available Ole B Suhr,1 Sandra Gustavsson,1 Victoria Heldestad,2 Rolf Hörnsten,3 Per Lindqvist,1 Erik Nordh,2 Urban Wiklund41Department of Public Health and Clinical Medicine, 2Department of Pharmacology and Clinical Neuroscience, 3Department of Surgical and Perioperative Sciences, Clinical Physiology, Heart Centre, 4Department of Radiation Sciences, Biomedical Engineering, Umeå University, Umeå, SwedenAbstract: Over the last decade, new medical treatment modalities have emerged based on increased insights into amyloid formation. With the increased possibilities for treatment of amyloidosis caused by transthyretin (TTR amyloid deposits comes the need for diagnostic procedures for early diagnosis and better tools to follow disease progression. This is of particular importance in clinical trials evaluating the efficacy of new treatments. Until recently, the treatment of TTR amyloidosis (ATTR was based solely on liver transplantation, a procedure that has halted disease progression in many patients. Liver transplantation has been especially effective in patients under the age of 50 years carrying the TTR V30M mutation, whereas the outcome of the procedure has been variable for others, particularly elderly male patients and those carrying a non-V30M mutation. This review concentrates on new insights derived from our center's experience with liver transplantation, how to implement this experience in evaluation of new treatment modalities for ATTR, and how to facilitate early diagnosis of neuropathy with easily available diagnostic tools. Attention has focused on manifestations of the disease that involve the heart and the peripheral nervous system; change in peripheral nerve function has been the primary endpoint in two controlled clinical trials, one finished and one ongoing. New insights into the amyloid formation process and the lessons learned from liver transplantation give the opportunity to design potentially effective treatment modalities for ATTR

  10. Experience of a single center with congenital hepatic fibrosis: A review of the literature

    Ali Shorbagi, Yusuf Bayraktar

    2010-02-01

    Full Text Available Congenital hepatic fibrosis (CHF is an autosomal recessive inherited malformation defined pathologically by a variable degree of periportal fibrosis and irregularly shaped proliferating bile ducts. It is one of the fibropolycystic diseases, which also include Caroli disease, autosomal dominant polycystic kidney disease, and autosomal recessive polycystic kidney disease. Clinically it is characterized by hepatic fibrosis, portal hypertension, and renal cystic disease. CHF is known to occur in association with a range of both inherited and non-inherited disorders, with multiorgan involvement, as a result of ductal plate malformation. Because of the similarities in the clinical picture, it is necessary to differentiate CHF from idiopathic portal hypertension and early liver cirrhosis, for which a liver biopsy is essential. Radiological tests are important for recognizing involvement of other organ systems. With regards to our experience at Hacettepe University, a total of 26 patients have been diagnosed and followed-up between 1974 and 2009 with a diagnosis of CHF. Presentation with Caroli syndrome was the most common diagnosis, with all such patients presenting with symptoms of recurrent cholangitis and symptoms related to portal hypertension. Although portal fibrosis is known to contribute to the ensuing portal hypertension, it is our belief that portal vein cavernous transformation also plays an important role in its pathogenesis. In all patients with CHF portal vein morphology should be evaluated by all means since portal vein involvement results in more severe and complicated portal hypertension. Other associations include the Joubert and Bardet-Biedl syndromes.

    2010-07-01

    Full Text Available Background: Pediatric hepatic malignancies are rare, accounting for 1-4% of all solid childhood tumors. The histopathology of childhood hepatic tumors guides the treatment and prognosis, and is the cornerstone for precise diagnosis. Until now, there has been no documented study on pediatric liver tumor cases from this center; in this report, we show our experience about the common types of childhood hepatic tumors during five years (2002-2007 and compare them with other studies. Materials and Methods: During five years (2002-2007, all the hepatic tumors of childhood (under 18 year-old from the pathology file of Namazi Hospital of Shiraz University of Medical Sciences are recorded. This includes both resected specimens and biopsies. All the slides were reviewed and the pathologic diagnosis was confirmed. Results: We detected 53 liver tumor cases in children (below 18 years of age. Among these tumors, 36 (67.9% were malignant. Male to female ratio was 1.5 to 1. Hepatoblastoma was the most common liver tumor in this age group accounting for 22 patients (41.5%. The second most common primary tumor was hepatocellular carcinoma (HCC, with five patients. Another malignant tumor was embryonal sarcoma. Benign tumors included adenoma, mesenchymal hamartoma, vascular tumors, focal nodular hyperplasia, and inflammatory pseudo tumor. There were also seven metastatic tumors during these five years. Conclusions: The spectrum of hepatic tumors in children is different from that found in the older age group (adults and also different in different populations.

    2016-03-17

    Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired disorder characterized by intravascular hemolysis. Real-world experience of PNH management is largely unreported. A retrospective analysis was undertaken based on medical records from six patients with PNH [two with aplastic anemia (AA)] treated at our center, Dicle University, Turkey. Diagnosis was based on granulocyte PNH clones, ranging from 93% to 66%. All patients had symptoms consistent with PNH. One patient was managed adequately with supportive measures only. Five were treated with the complement inhibitor eculizumab. Follow-up data (<1 year) were available in four cases (the fifth had received only three infusions by final follow-up). Hemoglobin level in these four patients increased from 4.1-7.2 g/dL to 8.3-13.0 g/dL. Lactate dehydrogenase, a marker for hemolysis, decreased profoundly in the two non-AA patients, with more minor improvements in the two AA patients. Weakness and fatigue improved in all eculizumab-treated patients. Four of the five treated patients became transfusion independent, including the patient given only three infusions. In the remaining case, a patient with AA, transfusion requirement decreased, and abdominal pain and dysphagia resolved. No adverse events occurred. PNH can be successfully managed in routine practice. PMID:27103981

  13. Adult Living Donor Liver Transplantation with ABO-Incompatible Grafts: A German Single Center Experience

    Armin D. Goralczyk

    2009-01-01

    Full Text Available Adult living donor liver transplantations (ALDLTs across the ABO blood group barrier have been reported in Asia, North Americas, and Europe, but not yet in Germany. Several strategies have been established to overcome the detrimental effects that are attached with such a disparity between donor and host, but no gold standard has yet emerged. Here, we present the first experiences with three ABO-incompatible adult living donor liver transplantations in Germany applying different immunosuppressive strategies. Four patient-donor couples were considered for ABO-incompatible ALDLT. In these patients, resident ABO blood group antibodies (isoagglutinins were depleted by plasmapheresis or immunoadsorption and replenishment was inhibited by splenectomy and/or B-cell-targeted immunosuppression. Despite different treatments ALDLT could safely be performed in three patients and all patients had good initial graft function without signs for antibody-mediated rejection (AMR. Two patients had long-term graft survival with stable graft function. We thus propose the feasibility of ABO-incompatible ALDLT with these protocols and advocate further expansion of ABO incompatible ALDLT in multicenter trials to improve efficacy and safety.

    2016-03-01

    Full Text Available Objective: To report our ureteroscopic laser lithotrip­sy experiences in the treatment of symptomatic ureter stones in pregnants which do not respond to conservative treatment Methods: A total of 6 pregnants aged between 22-33 years in second or third trimester were studied. Holmium-YAG laser lithotripsy was performed with 6.5 F semirigid uretroscope. Results: The diagnosis of ureter stone was made with ab­dominal ultrasonography in 5 patients and with magnetic resonance in one patient. Adequate stone fragmentation was performed in 2 mid-ureter and 4 distal-ureter stones. J stent was applied in one patient after the fragmenta­tion process. The mean operation time was 24.8 ± 10.0 minutes after the entry of bladder with ureteroscope un­der spinal anesthesia. No urologic, anesthetic or obstetric complication was seen and all patients gave healthy birth at term. Conclusion: Fine calibrated ureteroscopes for the treat­ment of ureter stones in pregnants are fast and effective treatment modalities which decrease the operation time and remove difficulties in entering the ureter.

    Bozkurt, Mehmet Abdussamet; Kocataş, Ali; Gemici, Eyüp; Kalaycı, Mustafa Uygar; Alış, Halil

    2016-01-01

    Objective: Robotic surgery was first introduced in 2000 especially to overcome the limitations of low rectum cancer surgery. There is still no consensus regarding the standard method for colorectal surgery. The aim of this study was to compare robotic surgery with laparoscopic colorectal surgery. Material and Methods: This is a retrospective study. Data of patients with a diagnosis of colon or rectal cancer were analyzed for robotic colorectal surgery and laparoscopic colorectal surgery. Results: The cost of robotic surgery group was statistically higher than the laparoscopic surgery group (p=0.032). The average operation duration was 178 minutes in the laparoscopic surgery group and 228 minutes in the robotic surgery group, and this difference was statistically significant (p=0.044). There was no statistically significant difference between the groups regarding other parameters. Discussion: Disadvantages of robotic surgery seem to be its higher cost and longer operation duration as compared to laparoscopic surgery. We claim that an increase in the number of cases and experience may shorten the operation time while the increase in commercial interest may decrease the cost disadvantage of robotic surgery.

    2015-09-01

    Full Text Available Background Testicular cancer accounts for about 1 - 1.5% of all malignancies in men. Radical orchiectomy is curative in 75% of patients with stage I disease, but advance stage with retroperitoneal lymph node involvement needs chemotherapy. All patients who have residual masses ≥ 1 cm after chemotherapy should undergo postchemotherapy retroperitoneal lymph node dissection (PC-RPLND. Objectives Treatment of advanced nonseminomatous testicular cancer is usually a combination of chemotherapy and surgery. We described our experience about postchemotherapy retroperitoneal lymph node dissection (PC-RPLND in our center. Patients and Methods In a retrospective cross-sectional study between 2006 and 2011, patients with a history of postchemotherapy retroperitoneal lymph node dissection (PC-RPLND in Imam Khomeini hospital were evaluated. All patients had normal postchemotherapy serum tumor markers and primary nonseminomatous cancer. We reviewed retrospectively clinical, pathological, and surgical parameters associated with PC-RPLND in our center. Results Twenty-one patients underwent bilateral PC-RPLND. Mean age was 26.3 years (ranged 16 - 47. Mean size of retroperitoneal mass after chemotherapy was 7.6 cm. Mean operative time was 198 minutes (120 - 246 minutes. Mean follow-up time was 38.6 months. Pathologic review showed presence of fibrosis/necrosis, viable germ cell tumor and teratoma in 8 (38.1%, 10 (47.6% and 3 (14.28% patients, respectively. One patient in postoperative period of surgery and three patients in two first years after surgery were expired. Of 17 alive patients, only two (11.8% had not retrograde ejaculation. Conclusions PC-RPLND is one the major operations in the field of urology, which is associated with significant adjunctive surgeries. In appropriate cases, PC-RPLND was associated with good cancer specific survival in tertiary oncology center.

    2013-06-01

    Laparoscopic splenectomy (LS) is nowadays considered as the gold standard for most hematological diseases where splenectomy is necessary, but many questions still remain. The aim of this study was to analyze our 5-years experiences consisting of 48 consecutive LS cases in order to assess the optimal approach and the feasibility of the procedure also in malignant diseases and unusual cases such as a primary spleen lymphoma, a big splenic artery aneurism, or a spleen infarct due to a huge pancreatic pseudo-cyst. Forty-eight consecutive patients underwent LS from January 2006 to January 2011 with at least 1-year follow-up. Clinical data and immediate outcome were retrospectively recorded; age, diagnosis, operation time, perioperative transfusion requirement, conversion rate, accessory incision, hospital stay, and complications were analyzed. We had 14 cases of malignant splenic disease, the most frequent malignant diagnosis was non-Hodgkin's lymphoma (12/14, 85.7 %). Splenomegaly (interpole diameter (ID) >20 cm) was observed in 12 cases (25 %) and massive splenomegaly (ID >25 cm) in 3 cases (6.25 %). Conversion to laparotomy occurred in two patients (4.16 %), both associated to uncontrollable bleeding in patients with splenomegaly. Mean operative time was 138 ± 22 min. Mean hospital stay was 4.5 days. Postoperative morbidity rate was 8.8 % for the benign group and 35.7 % in the malignant group. Mortality occurred in 1/48 patients (2.08 %), as a result of overwhelming post-splenectomy infection (OPSI). LS can be performed safely for malignant splenic disease and splenomegaly without any statistically significant increase of morbidity and mortality rate. Conversion rate is increased for massive splenomegaly. LS should be considered as the preferential approach even in patients with malignant disease, splenomegaly, or unusual cases. Massive splenomegaly should be considered as relative contraindication to LS even at experienced centers. PMID:23355349

    2011-01-01

    Full Text Available Background/Aim. Management of patients with recurrent glioblastoma (GB comprises a therapeutic challenge in neurooncology owing to the aggressive nature of the disease with poor local control despite a combined modality treatment. The majority of cases recur within the highdose radiotherapy field limiting the use of conventional techniques for re-irradiation due to potential toxicity. Stereotactic radiosurgery (SRS offers a viable noninvasive therapeutic option in palliative treatment of recurrent GB as a sophisticated modality with improved setup accuracy allowing the administration of high-dose, precise radiotherapy. The aim of the study was to, we report our experience with single-dose linear accelerator (LINAC based SRS in the management of patients with recurrent GB. Methods. Between 1998 and 2010 a total of 19 patients with recurrent GB were treated using single-dose LINAC-based SRS. The median age was 47 (23-65 years at primary diagnosis. Karnofsky Performance Score was ≥ 70 for all the patients. The median planning target volume (PTV was 13 (7-19 cc. The median marginal dose was 16 (10-19 Gy prescribed to the 80%-95% isodose line encompassing the planning target volume. The median follow-up time was 13 (2-59 months. Results. The median survival was 21 months and 9.3 months from the initial GB diagnosis and from SRS, respectively. The median progression-free survival from SRS was 5.7 months. All the patients tolerated radiosurgical treatment well without any Common Toxicity Criteria (CTC grade > 2 acute side effects. Conclusion. Single-dose LINAC-based SRS is a safe and well- tolerated palliative therapeutic option in the management of patients with recurrent GB.

    Immune thrombocytopenia (ITP) is an acute self-limited disease of childhood, mostly resolving within 6 months irrespective of whether therapy is given or not. Treatment options when indicated include corticosteroids, intravenous immune globulin (IVIG), and anti-RhD immunoglobulin. We reviewed our 32 years' experience for first-line therapy of acute ITP. Five hundred forty-one children (mean age: 5.3 years) diagnosed and treated for ITP were evaluated retrospectively. Among 491 acute ITP patients, IVIG was used in 27%, high-dose steroids in 27%, low-dose steroids in 20%, anti-D immunoglobulin G (IgG) in 2%, and no therapy in 22%. When the initial response (platelets >50 × 10(9)/L) to first-line treatment modalities were compared, 89%, 84%, and 78% patients treated by low-dose steroids, high-dose steroids, and IVIG responded to treatment, respectively (P > .05). Mean time to recovery of platelets was 16.8, 3.8, and 3.0 days in patients treated with low-dose steroids, high-dose steroids, and IVIG, respectively (P < .0001). Thrombocytopenia recurred in 23% of low-dose steroid, 39% of high-dose steroid, and in 36% of IVIG (P < .0001) treatment groups. Of 108 patients who were observed alone, 4 (3%) had a recurrence on follow-up and only 2 of these required treatment subsequently. Recurrence was significantly less in no therapy group compared with children treated with 1 of the 3 options of pharmacotherapy (P < .0001). Response rates were similar between patients treated by IVIG and low- and high-dose steroids; however, time to response was slower in patients treated with low-dose steroids compared with IVIG and high-dose steroids.

    Pasireotide is the first pituitary-directed drug approved for treating patients with Cushing's disease (CD). Our 10-year experience with pasireotide in CD is reported here. Twenty patients with de novo, persistent, or recurrent CD after pituitary surgery were treated with pasireotide from December 2003 to December 2014. Twelve patients were treated with pasireotide in randomized trials and 8 patients with pasireotide sc (Signifor(®); Novartis AG, Basel, Switzerland) in clinical practice. The mean treatment duration was 20.5 months (median 9 months; range, 3-72 months). Urinary free cortisol (UFC) levels mean percentage change (± SD) at last follow-up was-40.4% (± 35.1; range, 2-92%; median reduction 33.3%) with a normalization rate of 50% (10/20). Ten patients achieved sustained normalized late night salivary cortisol (LNSC) levels during treatment. LNSC normalization was associated with UFC normalization in 7/10 patients. Serum cortisol and plasma ACTH significantly decreased from baseline to last follow-up. Body weight decrease and blood pressure improvement during pasireotide treatment were independent from UFC response. Glucose profile worsening was observed in all patients except one. The frequency of diabetes mellitus increased from 40% (8/20) at baseline to 85% (17/20) at last follow-up requiring initiation of medical treatment only in 44% of patients. Pasireotide treatment was associated with sustained biochemical and clinical benefit in about 60% of CD patients. Glucose profile alteration is a frequent complication of pasireotide treatment; however, it seems to be easy to manage with diet and lifestyle intervention in almost half of the patients.

    Total joint arthroplasty (TJA) improves the quality of life for patients with end-stage osteoarthritis but is associated with an increased risk of venous thromboembolism (VTE), thus pharmacologic thromboprophylaxis is recommended for most patients. Patients with congenital bleeding disorders may develop severe arthropathies due to repeated hemarthroses and derive similar benefit from TJA as the general population. No guidelines for pharmacologic thromboprophylaxis in this population exist, however, as the risks and benefits are not well defined. We undertook the current study to assess the safety and efficacy of pharmacologic VTE prophylaxis in patients with congenital bleeding disorders undergoing TJA. We retrospectively reviewed the medical records of patients with bleeding disorders who underwent TJA at our academic institution between 1987 and 2012. We identified 28 patients who underwent 38 TJA procedures. Low-molecular-weight heparin (LMWH) was administered in 29 procedures (76%) and was discontinued early in 3 procedures (2 patients) due to nonjoint bleeding. No symptomatic VTE was identified, and no joint or deep wound infections were seen. Twenty-two patients accounting for 31 procedures were contacted to discuss their experience with TJA. All reported decreased pain, and 97% reported improved function after the surgery. Impressively, 97% stated that they would choose to have the surgery again. These results confirm the benefit of TJA in patients with congenital bleeding disorders and end-stage arthropathies and suggest that LMWH thromboprophylaxis is safe. No patient in our cohort developed symptomatic VTE, whether or not thromboprophylaxis was administered, thus necessity of thromboprophylaxis remains an unanswered question. PMID:27099385

    2010-01-01

    Transplant tourism is a necessity for children with end-stage renal disease living in regions without established local transplantation programs. The use of kidneys from living unrelated donors (LURDs) was common practice in Asia prior to the recent global condemnation of commercial organ transplantation. Objective information on the outcomes of pediatric transplant tourism is scarce. Here, we report the Dubai experience with 45 renal allograft transplantations performed outside the United Arab Emirates (UAE) between 1993 and 2009. Transplantation from 33 LURDs, ten living related donors (LRDs) and two deceased donors was performed in 14 different countries. The mean number of human leukocyte antigen (HLA) A/B/DR allele matches was 1.4 +/- 0.8 in the LURD graft recipients and 3.9 +/- 0.7 in the LRD recipients. Outcomes were compared with those of a matched group of 3,150 pediatric LRD transplantations from the Collaborative Transplant Study (CTS). Ten-year patient survival was 100% in the LRD patients, 91.2% in the LURD patients, and 92% in the CTS patients. The three deaths in the LURD group occurred within the first 4 months after transplantation and were related to acute rejection. One-year and 10-year graft survival was 100% in the LRD group and 94.8% and 66.7% in the CTS-LRD groups, vs 87.8% and 43.4% in the LURD group. Major viral infections [Epstein-Barr virus (EBV), cytomegalovirus (CMV), varicella zoster (VZV)] were four-times more common in patients that had received LURD grafts than in those that had received LRD grafts. In conclusion, whereas LRD kidney transplantation performed abroad yields excellent long-term results, transplantation of LURD kidneys is fraught with a high complication rate affecting graft and even early patient survival.

    Full Text Available Food induced sensitization has been reported in pediatric liver recipients. However long term follow up has not been established so far. We report here our experience regarding 3 pediatric patients who developed acquired food allergy after liver transplantation. The first patient suffered from persistent diarrhea and eczema. The second one presented with abdominal pain with no signs of rejection, abdominal discomfort, vomiting when ingesting milk proteins and responded well to the elimination diet. The third patient presented with facial angioedema and hoarseness of voice. She had multiple food allergies and reacted to milk, egg and sesame. All the patients had elevated total Immunoglobulin E (IgE and elevated specific IgE antibodies to the implicated food allergens. The first patient presented clinical manifestations of allergy when she was 19 months old. The second patient became allergic at the age of 16 and the third patient at the age of 3. The symptoms of food allergy persisted for 8 years in the first case and for 2 years in the other two cases. Low levels of specific IgE antibodies to the implicated food allergens and an enhanced T-helper 1 cell immune response toward interferon-gamma production were markers of tolerance acquisition. The long term prognosis in our cases was excellent. Food allergy resolved in all the patients. The long term prognosis of acquired food allergy after liver transplantation is currently obscure. More studies would be needed including greater number of patients to determine whether acquired food allergy is transient in pediatric liver recipients.

    Full Text Available Purpose: To report our early experience in image-guided chemoport insertions by interventional radiologists. Materials and Methods: This was a cross-sectional study conducted in a tertiary center with 161 chemoport insertions done from June 2008 to June 2010. The chemoports were inserted either at the angiography suite or at the mobile operation theater unit. Ninety percent of the chemoports had right internal jugular vein (IJV as the entry site. Other entry sites included the left IJV, subclavian veins and the inferior vena cava. Immediate and early complications were recorded. All insertions were performed under image guidance with the aid of ultrasound and fluoroscopy. Results: The technical success rate was 99.4%. In terms of immediate complications, there were only two cases of arterial puncture that resolved with local compression. No pneumothorax or air embolism was documented. Twenty-six early complications were recorded. The most common early complication was catheter blockage (12/161; 7.4%, followed by catheter-related infection (9/161; 5.6%. Other complications were catheter malposition, venous thrombosis and catheter dislodgement or leak. A total of 11 (6.8% chemoports had to be removed within 30 days; most of them were due to infections that failed to respond to systemic antibiotic therapy. In terms of place of procedure, there were no significant differences in complication rates between the angiography suite and the mobile operation theater unit. Conclusion: Image-guided chemoport insertion by interventional radiologist gives low periprocedural complication rates. Using right IJV as the entry site, the image guidance gives good success rate with least complication.

    Full Text Available Objectives: The safety and efficacy of transrectal ultrasound (TRUS guided aspiration of prostatic abscess (PA is known. The objective of this study is to describe a treatment algorithm for management of PA with TRUS-guided aspiration, emphasizing on indications and factors predicting the treatment outcome. Materials and Methods: After the institutional review board approval was obtained, a retrospective study was done of all patients suspected with PA on digital rectal examination (DRE and confirmed on TRUS. An 18-gauge two-part needle was used for aspiration. The real-time TRUS-guided aspiration of PA was done in the longitudinal axis. The aspiration of pus and the sequential collapse of cavity was seen "real time." A suprapubic catheter was placed, if the patient had urinary retention, persistent dysuria, and/or severe lower urinary tract symptoms (LUTS. Success was defined as complete resolution of the abscess and/or symptoms. Results: Forty-eight patients were studied with PA, with a mean age of 54.6 ± 14.6 (range 26-79 years. The DRE diagnosed PA in 22 (45.83% patients, while abdominal sonography diagnosed PA in 13 (27.08% patients. TRUS revealed a hypoechoic area with internal echoes in all 48 (100% patients. The diagnosis was confirmed in all 48 cases with aspiration. The mean size of the lesion was 3.2 ± 1.2 (range 1.5-8 cm. Mean volume aspirated was 10.2 ml (range 2.5-30 ml. Complete resolution after first aspiration was observed in 20 (41.66% patients. An average of 4.1 (range 1-7 aspirations was required for complete resolution which was seen in 41 patients (85.42%. Seven (14.58% patients required transurethral resection (deroofing of the abscess cavity. We formulated a treatment algorithm based on the above findings. Conclusion: The proposed algorithm based on our experience suggests that patients with PA larger than 2 cm with severe LUTS and/or leukocytosis benefit from TRUS-guided aspiration. In addition, these patients are

    Background Orthotopic liver retransplantation (re-OLT) is the only effective therapy for irreversible failure of a liver graft. Early and late graft failure gives way to two different clinical conditions that should be discussed separately. This study was designed to compare early and late re-OLT for patients with poor graft function after primary transplantation at our center and sum up our clinical experience in re-OLT.Methods The clinical data of 31 re-OLTs at our center from January 2004 to February 2007 were analyzed retrospectively, consisting of the first group with 14 cases of early re-OLT and the second group with 17 cases of late re-OLT.Results Biliary tract complications were the main indications for early re-OLT (57.1%) and late re-OLT (52.9%). Other common indications were vascular complications in early re-OLT and recurrence of primary diseases in late re-OLT. No significant differences were found between the groups with regard to the volume of bleeding during operation, cold ischemia time, operative duration, and perioperative mortality; except for the model of end-stage liver disease (MELD) score. Outcome was fatal for 7 patients in early re-OLT and 9 patients in late re-OLT. Two deaths were due to multiple organ failure with 3 deaths due to severe sepsis-related disease in early re-OLT, and 4 deaths were due to severe sepsis-related disease with 3 deaths due to recurrence of hepatocellular carcinoma (HCC) in late re-OLT. One and 2-year actuarial survival rates after re-OLT were 55.2% and 36.9%, respectively, for patients in early re-OLT, and 65.1% and 52% respectively, for patients in late re-OLT. No significant differences were found regarding survival rates between the two groups.Conclusions Similar clinical results can be achieved in early and late re-OLT. Proper indications and optimal operation timing, adequate preoperative preparation, experienced surgical procedures, and effective perioperative anti-infection strategy contribute to the

The management of PTLD poses a major therapeutic challenge and although there is reasonable agreement about the overall principles of treatment, there is still considerable controversy about the optimal treatment of individual patients. EBV-related PTLDs are a significant cause of mortality in patients undergoing orthotopic liver transplantation with the observed mortality rate of up to 50%.

  11. Single-center experience in pediatric renal transplantation using thymoglobulin induction and steroid minimization.

    Warejko, Jillian K; Hmiel, S Paul

    2014-12-01

    Our center has offered thymoglobulin induction with steroid minimization to our pediatric renal transplant patients for the last 10 yr. Steroid minimization or avoidance has shown favorable results in survival, kidney function, and growth in previous studies of pediatric patients. We report our experience with this protocol over the past 10 yr with respect to patient/graft survival, acute rejection episodes, renal function, linear growth, bone density, cardiovascular risk factors, and opportunistic infections. A retrospective chart review was performed for pediatric renal transplant patients on the steroid-minimized protocol between January 2002 and December 2011 on an intention to treat basis. Patient demographics, height, weight, serum creatinine, iGFR, biopsies, and survival data were collected. Height and weight z-scores were calculated with EpiInfo 7, using the CDC 2000 growth charts. Survival was calculated using Kaplan-Meier analysis. eGFR was calculated using the original and modified Schwartz equations. Forty-four pediatric patients were identified, aged 13 months to 19 yr. Five-yr survival was 95.5% for males and 94.4% for females. Only five patients had biopsy-proven ACR, two of which were at more than 12 months post-transplantation. Height delta z-scores from transplant to one, three, and five yr were 0.34, 0.38, and 0.79, respectively. Weight delta z-scores from transplant to one, three, and five yr were 0.87, 0.79, and 0.84, respectively. Mean original Schwartz eGFR was 84.3 ± 15.8 mL/min/1.73 m(2) , modified Schwartz eGFR was 59.3 ± 11.5 mL/min/1.73 m(2) , and iGFR was 64.2 ± 8.5 mL/min/1.73 m(2) at three yr. Of 18 subjects who had a bone density exam, none had a z-score less than -2 on DEXA exam at one-yr post-transplantation. Fifty-one percent of patients were on antihypertensives at the time of transplant compared with 43% at one-yr post-transplantation. Three yr post-transplantation, the average LDL was <100 mg/dL, and

    Full Text Available Acute kidney injury (AKI is becoming more prevalent among hospitalized children, its etiologies are shifting, and new treatment modalities are evolving; however, diarrhea-associated hemolytic uremic syndrome (D+HUS remains the most common primary disease causing AKI in young children. Little has been published about acute renal replacement therapy (ARRT and its challenges in this population. We describe our single center's experience managing 134 pediatric patients with D+HUS out of whom 58 (43% required ARRT over the past 16 years. In our cohort, all but one patient were started on peritoneal dialysis (PD. Most patients, 47 (81%, received acute PD on a pediatric inpatient ward. The most common recorded complications in our cohort were peritoneal fluid leaks 13 (22%, peritonitis 11 (20%, and catheter malfunction 5 (9%. Nine patients (16% needed surgical revision of their PD catheters. There were no bleeding events related to PD despite a mean platelets count of 40.9 (±23.5 × 103/mm3 and rare use of platelets infusions. Despite its methodological limitations, this paper adds to the limited body of evidence supporting the use of acute PD as the primary ARRT modality in children with D+HUS.

    The role of image-guided thermal ablation techniques for the nonoperative local management of painful osseous metastatic disease has expanded during recent years, and several advantages of cryoablation in this setting have emerged. The purpose of this study is to retrospectively evaluate and report a single-center experience of CT-guided percutaneous cryoablation in the setting of painful musculoskeletal metastatic disease. This study was approved by the institutional review board and is compliant with the Health Insurance Portability and Accountability Act. Electronic medical records of all patients who underwent percutaneous image-guided palliative cryoablation at our institution were reviewed (n = 61). An intent-to-treat analysis was performed. Records were reviewed for demographic data and anatomical data, primary tumor type, procedure details, and outcome - including change in analgesic requirements (expressed as morphine equivalent dosages), pain scores (utilizing the clinically implemented visual analog scale), subsequent therapies (including radiation and/or surgery), and complications during the 24 h following the procedure and at 3 months. Patients were excluded (n = 7) if data were not retrospectively identifiable at the defined time points. Fifty-four tumors were ablated in 50 patients. There were statistically significant decreases in the median VAS score and narcotic usage at both 24 h and 3 months (p < 0.000). Six patients (11 %) incurred complications related to their therapy. Two patients had no relief at 24 h, of which both reported worsened pain at 3 months. One patient had initial relief but symptom recurrence at 3 months. Four patients went on to have radiation therapy of the ablation site at some point following the procedure. CT-guided cryoablation is a safe, effective, reproducible procedural option for the nonoperative local treatment of painful musculoskeletal metastatic disease. (orig.)

  17. Safety of atrial fibrillation ablation with novel multi-electrode array catheters on uninterrupted anticoagulation-a single-center experience.

    Hayes, Christopher Ruslan

    2012-02-01

    INTRODUCTION: A recent single-center report indicated that the performance of atrial fibrillation ablation in patients on uninterrupted warfarin using a conventional deflectable tip electrode ablation catheter may be as safe as periprocedural discontinuation of warfarin and bridging with heparin. Novel multi-electrode array catheters for atrial fibrillation ablation are currently undergoing clinical evaluation. While offering the possibility of more rapid atrial fibrillation ablation, they are stiffer and necessitate the deployment of larger deflectable transseptal sheaths, and it remains to be determined if they increase the risk of cardiac perforation and vascular injury. Such potential risks would have implications for a strategy of uninterrupted periprocedural anticoagulation. METHOD AND RESULTS: We audited the safety outcomes of our atrial fibrillation ablation procedures using multi-electrode array ablation catheters in patients on uninterrupted warfarin (CHADS2 score>or=2) and in patients not on warfarin (uninterrupted aspirin). Two bleeding complications occurred in 49 patients on uninterrupted warfarin, both of which were managed successfully without longterm sequelae, and no bleeding complication occurred in 32 patients not on warfarin (uninterrupted aspirin). There were no thromboembolic events or other complication with either anticoagulant regimen. CONCLUSION: Despite the larger diameter and increased stiffness of multi-electrode array catheters and their deflectable transseptal sheaths, their use for catheter ablation in patients with atrial fibrillation on uninterrupted warfarin in this single-center experience does not appear to be unsafe, and thus, an adequately powered multicenter prospective randomized controlled trial should be considered.

    Background Brugada syndrome is an arrhythmogenic disease characterized by an ECG pattern of ST-segment elevation in the right precordial leads and an increase risk of sudden cardiac death.

    In developing countries, it is important to ascertain the safety of performing allogeneic hematopoietic SCT (HSCT) in single rooms without high-efficiency particulate air (HEPA) filters. We present our experience of performing 40 such transplants from July 2004 to November 2007. Source of stem cells was peripheral blood in 33, bone marrow in six and combined in one. G-CSF started from day +1. The indications were SAA-18, CML-7, AML-7, ALL-2, myelodysplastic syndrome-2 and thalassemia major-4. The median age was 19 years (range 2.2-46) with 29 male and 11 female participants. Antibacterial and antifungal prophylaxis was administered along with conditioning, and at the onset of fever, systemic antibiotics were started. Antifungal agents were added if fever persisted for 3 days. Median time for neutrophil engraftment was 10 days (range 8-17). Fever occurred in 38 (95%) for a median of 5 days (range 1-38), and blood cultures were positive in seven (17.5%). Systemic antibiotics were used in 95% and antifungals in 57.5% cases. The 30-day mortality was nil, and 100-day mortality was 1 (2.5%). After day 100, there were eight fatalities (20%) due to chronic GVHD-3, relapse-2, graft rejection-2, disseminated tuberculosis and aspergillosis-1. Our experience suggests that allogeneic HSCT can be safely performed in non-HEPA filter rooms in India. PMID:18794872

    Full Text Available Abstract Deep sternal infections, also known as poststernotomy mediastinitis, are a rare but often fatal complication in cardiac surgery. They are a cause of increased morbidity and mortality and have a significant socioeconomic aspect concerning the health system. Negative pressure wound therapy (NPWT followed by muscular pectoralis plasty is a quite new technique for the treatment of mediastinitis after sternotomy. Although it could be demonstrated that this technique is at least as safe and reliable as other techniques for the therapy of deep sternal infections, complications are not absent. We report about our experiences and complications using this therapy in a set of 54 patients out of 3668 patients undergoing cardiac surgery in our institution between January 2005 and April 2007.

  4. Use of Self-Expanding Stents for the Treatment of Vertebral Artery Ostial Stenosis: a Single Center Experience

    To evaluate our early experience using self-expanding stents to treat atherosclerotic vertebral artery ostial stenosis (VAOS), with respect to technical feasibility and clinical and imaging follow-up results. A total of 20 lesions in 20 patients underwent stenting of the VAOS using a self-expanding stent (Precise RX; Cordis Neurovascular, Miami Lakes, FL). Two patients were asymptomatic. We analyzed the technical success rate, causes of technical failure, occurrence of any vascular or neurological event, and the occurrence of any neurological abnormality or in-stent restenosis (ISR) seen on follow-up. The imaging follow-up was performed with Doppler ultrasound (DUS) as a primary screening modality. One instance of technical failure was caused by failure of the guidewire passage. The stent diameter was 5 mm, and post-stenting balloon dilatations were necessary in all cases. Stent misplacement requiring placement of an additional stent occurred in four cases. Following a 14.8 month average clinical follow-up time, two patients showed anterior circulation ischemia, which was not attributed to the VAOS we treated. Following a 13.7 month average DUS follow-up, five patients showed a mild degree of diffuse or focal intimal thickening in the stent lumen; however, none of the stenosis showed luminal loss of more than 50% and no stent fracture was noted. The use of self-expanding stents for treating VAOS was technically feasible and helped to improve artery patency during our limited follow-up interval

  5. Outcomes Following Iodine-125 Monotherapy for Localized Prostate Cancer: The Results of Leeds 10-Year Single-Center Brachytherapy Experience

    Purpose: This study reports the 10-year experience of permanent brachytherapy monotherapy at a single UK center. Methods and Materials: Between March 1995 and September 2004, 1,298 patients underwent trans-rectal ultrasound (TRUS) planned transperineal brachytherapy delivering 145 Gy using I-125. No patient received supplemental external beam; 44.2% received neoadjuvant hormones. In 688, CT postimplant dosimetry was available. Outcome data were analyzed in terms of overall survival (OS), disease specific survival (DSS), and PSA relapse-free survival (PSA-RFS). Results: The mean age was 62.9 (range, 34-83) years. Median follow-up was 4.9 years (range, 2.03-11.7 years). OS and DSS were 85% and 95%, respectively, at 10 years. Twenty-one patients died from prostate cancer (1.6%) and 34 (2.5%) from unrelated causes. Seventy-four (5.7%) developed evidence of clinical failure. Overall PSA-RFS was 79.9% and 72.1% at 10 years (American Society for Therapeutic Radiology and Oncology [ASTRO] and Nadir+2 definitions, respectively). Higher presenting PSA or Gleason score and use of neoadjuvant hormones were associated with an increased risk of biochemical failure (p 90 ≥140 Gy and in 78% of patients with D90 90 with biochemical control.

  6. The role of interventional radiology in biliary complications after orthotopic liver transplantation: a single-center experience

    This study evaluated interventional radiological experience in the management of biliary complications of OLT at the National Cancer Institute of Milan. Seventeen patients who had undergone orthotopic liver transplantation in various hospital were referred to our unit with biliary complications. Group I consisted of 8 patients with anastomotic biliary fistula who came to our attention a short time after transplantation. Group II consisted of 9 patients with anastomotic strictures who came to our attention in a longer period. Two different interventional radiological approaches were used: (a) percutaneous transhepatic biliary drainage (PTBD) in the presence of fistulas in patients of group I; and (b) percutaneous transhepatic biliary drainage combined with dilatation of the strictures with a balloon catheter in patients of group II. On the whole resolution of the biliary complications was achieved in 13 of the 17 cases treated (76.5%), 5 of 8 in group I and 8 of 9 in group II. No secondary stenosis after PTBD were observed in group I, whereas two patients of group II needed a second dilatation. Percutaneous biliary drainage is indicated as a valid treatment in the management of biliary complications, either to allow closure of the fistula either to perform balloon dilatation of stenosis.

    Background: Percutaneous nephrostomy (PCN) has been established as an effective technique for urinary decompression or diversion. This procedure may be performed with the guidance of fluoroscopy, ultrasonography, a combination of fluoroscopy and ultrasonography, computed tomography (CT), or magnetic resonance imaging. Purpose: To retrospectively review experience with CT-guided PCN over a 10-year period in a single center. Material and Methods: All CT-guided PCN procedures performed in adults at our institution between 1995 and 2005 were evaluated. In 882 patients, 1113 nephrostomy catheters were inserted. Interventional radiologists or radiology residents under direct attending supervision inserted all catheters. During the PCN procedure, bleeding, sepsis, and injuries to adjacent organs were regarded as major complications. Clinical events requiring nominal therapy with no sequelae were regarded as minor complications. Results: PCN procedures were performed via 1-3 punctures in patients with grades 0-1 and 2 hydronephrosis, and via 1-2 punctures in patients with grade 3 hydronephrosis. They were carried out with a procedure time ranging from 9 to 26 min. All PCNs were considered as technically successful, and no major complications were observed. There were minor complications including transient macroscopic hematuria (28.6%, 19.9%, and 4.9% in patients with hydronephrosis grades 0-1, 2, and 3, respectively) and perirenal hematomas in a total of eight patients. No patient required additional intervention secondary to complications of the PCN procedure. Conclusion: CT-guided PCN is an efficient and safe procedure with major and minor complication rates below the accepted thresholds. It can be used for the management of patients requiring nephrostomy insertion in inpatient settings, and might be a preferable procedure in patients with minimal or no dilatation of the renal pelvis.

    Full Text Available Introduction/Purpose: The outbreak of methanol poisoning described in this paper occurred in Ahmedabad, Gujarat, India in July 2009. Our intention is to share the experience of clinical features, laboratory investigations and their relation during this tragedy. Materials and Methods: Single center, retrospective study of clinical features and laboratory parameters of 178 cases of methanol toxicity treated at tertiary care hospital in Ahmedabad, Gujarat. Results: Maximum patients (39.8%, n = 45 were received in 48 h; Mean age of presentation was 41.9 ± 10.2 years. Most of them were men (175 out of 178. On presentation, 83% patients had gastro-intestinal symptoms, 46% had neurological symptoms, 73% had visual symptoms and 32% had dyspnoea. 62% had blurred vision, 10.5% had blindness. Patients with visual symptoms had high mean level of methanol (120.12 ± 23.12 vs. 55.43 ± 29.24, P = 0.014. On fundus examination 52.8% (n = 62 had bilateral hyperaemia of discs, 8.4% (n = 12 had bilateral disc pallor and 4.5% had papilledema (n = 5. Patients with hyperaemia of discs, discs pallor or papilledema, had higher mean methanol level (121.1 ± 32.2 mg% v/s 70.1 ± 23.2 mg%, P = 0.032. Mean of pH values was 7.17 ± 0.22 and bicarbonate was 12.3 ± 7.3 mmol/L. Both pH and bicarbonate levels correlated well with mortality and serum methanol level. Mean serum methanol level was 87.1 mg/dL, and correlated significantly with the mortality (53.1 ± 41 mg/dL v/s 121 ± 92 mg/dL, P value < 0.05. Conclusion: GI symptoms, neurological symptoms and breathlessness are important clue to ED physician for diagnose methanol poisoning. Visual symptoms and fundus findings correlate well with the methanol level. Arterial Blood Gas derived pH and bicarbonate levels correlate significantly with the methanol level and mortality.

    Full Text Available Background. Factors affecting outcomes after orthotopic liver transplantation (OLT for hepatocellular carcinoma (HCC have been extensively studied, but some of them have only recently been discovered or reassessed. Methods. We analyzed classical and more recently emerging variables with a hypothetical impact on recurrence-free survival (RFS in a single-center series of 283 patients transplanted for HCC between 1997 and 2009. Results. Five-year patient survival and RFS were 75% and 86%, respectively. Thirty-four (12% patients had HCC recurrence. Elevated preoperative alpha-fetoprotein (AFP levels, preoperative treatments of HCC, unfulfilled Milan and up-to-seven criteria at final histology, poor tumor differentiation, and tumor microvascular invasion negatively affected RFS by univariate analysis. Milan and up-to-seven criteria applied preoperatively, and the use of m-TOR inhibitors did not reach statistical significance. Cox's proportional hazard model showed that only elevated AFP levels (Odds Ratio=2.88; 95% C.I.=1.43–5.80; =.003, preoperative tumor treatments (Odds Ratio=4.84; 95% C.I.=1.42–16.42; =.01, and microvascular invasion (Odds Ratio=4.82; 95% C.I.=1.87–12.41; =.001 were predictors of lower RFS. Conclusions. Biological aggressiveness and preoperative tumor treatment, rather than traditional and expanded dimensional criteria, conditioned the outcomes in patients transplanted for HCC.

  14. Late angiographic and clinical follow-up results of 100 consecutive aneurysms treated with Onyx reconstruction: largest single-center experience

    We present the long-term clinical and angiographic follow-up results of 100 consecutive intracranial aneurysms treated with Onyx liquid embolic system (MTI, Irvine, Calif.), either alone or combined with an adjunctive stent, in a single center. A total of 100 aneurysms in 94 patients were treated with endosaccular Onyx packing. Intracranial stenting was used adjunctively in 25 aneurysms including 19 during initial treatment and 6 during retreatment. All aneurysms except two were located in the internal carotid artery. Of the 100 aneurysms, 35 were giant or large/wide-necked, and 65 were small. Follow-up angiography was performed in all 91 surviving patients (96 aneurysms) at 3 and/or 6 months. Follow-up angiography was performed at 1, 2, 3, 4 and 5 years in 90, 41, 26, 6 and 2 patients, respectively. Overall, aneurysm recanalization was observed in 12 of 96 aneurysms with follow-up angiography (12.5%). All 12 were large or giant aneurysms, resulting in a 36% recanalization rate in the large and giant aneurysm group. One aneurysm out of 25 treated with the combination of a stent and Onyx showed recanalization. There was also no recanalization in the follow-up of small internal carotid artery aneurysms treated with balloon assistance only. At final follow-up, procedure- or device-related permanent neurological morbidity was present in eight patients (8.3%). There were two procedure-related and one disease-related (subarachnoid hemorrhage) deaths (mortality 3.2%). Delayed spontaneous asymptomatic occlusion of the parent vessel occurred in two patients, detected on routine follow-up. Onyx provides durable aneurysm occlusion with parent artery reconstruction resulting in perfectly stable 1-year to 5-year follow-up angiography both in small aneurysms treated with balloon assistance only (0% recanalization rate) and large or giant aneurysms treated with stent and Onyx combination (4% recanalization rate). Endosaccular Onyx packing with balloon assistance may not be

    2016-04-01

    Coronary allograft vasculopathy (CAV) is the leading cause of graft failure in pediatric heart transplant recipients, also adding to mortality in this patient population. Coronary angiography is routinely performed to screen for CAV, with conventional single-plane or bi-plane angiography being utilized. Dual-axis rotational coronary angiography (RA) has been described, mostly in the adult population, and may offer reduction in radiation dose and contrast volume. Experience with this in the pediatric population is limited. This study describes a single-institution experience with RA for screening for CAV in pediatric patients. The catheterization database at our institution was used to identify pediatric heart transplant recipients having undergone RA to screen for CAV. Procedural data including radiation dose, fluoroscopy time, contrast volume, and procedure time were collected for each catheterization. The number of instances in which RA was not successful, ECG changes were present, and CAV was detected were also collected for each catheterization. A total of 97 patients underwent 345 catheterizations utilizing RA. Median radiation dose-area product per kilogram was found to be 341.7 (mGy cm(2)/kg), total air kerma was 126.8 (mGy), procedure time was 69 min, fluoroscopy time was 9.9 min, and contrast volume was 13 ml. A total of 17 (2 %) coronary artery injections out of 690 could not be successfully imaged using RA. A total of 14 patients had CAV noted at any point, 10 of whom had progressive CAV. Electrocardiographic changes were documented in a total of 10 (3 %) RA catheterizations. Procedural characteristics did not differ between serial catheterizations. RA is safe and feasible for CAV screening in pediatric heart transplant recipients while offering coronary imaging in multiple planes compared to conventional angiography. PMID:26846123

    Full Text Available Abstract Objective Orthotopic-liver-transplantation (OLT in patients with Human-Immunodeficiency-Virus infection (HIV and end-stage-liver-disease (ESDL is rarely reported. The purpose of this study is to describe our institutional experience on OLT for HIV positive patients. Material and methods This is a retrospective study of all HIV-infected patients who underwent OLT at the University Hospital of Essen, from January 1996 to December 2009. Age, sex, HIV transmission-way, CDC-stage, etiology of ESDL, concomitant liver disease, last CD4cell count and HIV-viral load prior to OLT were collected and analysed. Standard calcineurin-inhibitors-based immunosuppression was applied. All patients received anti-fungal and anti-pneumocystis carinii pneumonia prophylaxis post-OLT. Results Eight transplanted HIV-infected patients with a median age of 46 years (range 35-61 years were included. OLT indications were HCV (n = 5, HBV (n = 2, HCV/HBV/HDV-related cirrhosis (n = 1 and acute liver-failure (n = 1. At OLT, CD4 cell-counts ranged from 113-621 cells/μl, and HIV viral-loads from Conclusions OLT in HIV-infected patients and ESLD is an acceptable therapeutic option in selected patients. Long-term survival can be achieved without HIV disease-progression under antiretroviral therapy and management of the viral hepatitis co-infection.

  17. Predictive Parameters of CyberKnife Fiducial-less (XSight Lung) Applicability for Treatment of Early Non-Small Cell Lung Cancer: A Single-Center Experience

    Purpose: To determine which parameters allow for CyberKnife fiducial-less tumor tracking in stereotactic body radiation therapy (SBRT) for early-stage non-small cell lung cancer. Methods and Materials: A total of 133 lung SBRT patients were preselected for direct soft-tissue tracking based on manufacturer recommendations (peripherally located tumors ≥1.5 cm with a dense appearance) and staff experience. Patients underwent a tumor visualization test to verify adequate detection by the tracking system (orthogonal radiographs). An analysis of potential predictors of successful tumor tracking was conducted looking at: tumor stage, size, histology, tumor projection on the vertebral column or mediastinum, distance to the diaphragm, lung-to-soft tissue ratio, and patient body mass index. Results: Tumor visualization was satisfactory for 88 patients (66%) and unsatisfactory for 45 patients (34%). Median time to treatment start was 6 days in the success group (range, 2-18 days) and 15 days (range, 3-63 days) in the failure group. A stage T2 (P=.04), larger tumor size (volume of 15.3 cm3 vs 6.5 cm3 in success and failure group, respectively) (P3 vs 0.79 g/cm3) were predictive of adequate detection. There was a 63% decrease in failure risk with every 1-cm increase in maximum tumor dimension (relative risk for failure = 0.37, CI=0.23-0.60, P=.001). A diameter of 3.6 cm predicted a success probability of 80%. Histology, lung-to-soft tissue ratio, distance to diaphragm, patient's body mass index, and tumor projection on vertebral column and mediastinum were not found to be predictive of success. Conclusions: Tumor size, volume, and density were the most predictive factors of a successful XSight Lung tumor tracking. Tumors >3.5 cm have ≥80% chance of being adequately visualized and therefore should all be considered for direct tumor tracking

Median time to treatment start was 6 days in the success group (range, 2-18 days) and 15 days (range, 3-63 days) in the failure group. A stage T2 (P=.04), larger tumor size (volume of 15.3 cm{sup 3} vs 6.5 cm{sup 3} in success and failure group, respectively) (P<.0001), and higher tumor density (0.86 g/cm{sup 3} vs 0.79 g/cm{sup 3}) were predictive of adequate detection. There was a 63% decrease in failure risk with every 1-cm increase in maximum tumor dimension (relative risk for failure = 0.37, CI=0.23-0.60, P=.001). A diameter of 3.6 cm predicted a success probability of 80%. Histology, lung-to-soft tissue ratio, distance to diaphragm, patient's body mass index, and tumor projection on vertebral column and mediastinum were not found to be predictive of success. Conclusions: Tumor size, volume, and density were the most predictive factors of a successful XSight Lung tumor tracking. Tumors >3.5 cm have ≥80% chance of being adequately visualized and therefore should all be considered for direct tumor tracking.

Self-monitoring of creatinine in addition to blood pressure at home could alleviate the burden of frequent outpatient visits, but only if patients are willing to self-monitor and if they adhere to the self-monitoring measurement regimen. A prospective pilot study was conducted to assess patients’ experiences and satisfaction.Materials and methods: For 3 months after transplantation, 30 patients registered self-measured creatinine and blood pressure values in an online record to which their physician had access to. Patients completed a questionnaire at baseline and follow-up to assess satisfaction, attitude, self-efficacy regarding self-monitoring, worries, and physician support. Adherence was studied by comparing the number of registered with the number of requested measurements.Results: Patients were highly motivated to self-monitor kidney function, and reported high levels of general satisfaction. Level of satisfaction was positively related to perceived support from physicians (P<0.01, level of self-efficacy (P<0.01, and amount of trust in the accuracy of the creatinine meter (P<0.01. The use of both the creatinine and blood pressure meter was considered pleasant and useful, despite the level of trust in the

    Full Text Available Objective: Posterior urethral valves (PUV are the most common cause of bladder outlet obstruction in infancy that impair renal and bladder function. This study was planned to evaluate and record the various clinical presentations and management, complications, and surgical management and long-term outcome of PUV.Methods: In a retrospective study, 98 patients who have been treated for PUV are evaluated in Mofid Children’s Hospital from January 2007 to December 2012. Detailed history taken and paraclinical examinations were performed in each patient and diagnosis was confirmed by voiding-cysto-urethrography (VCUG. PUV had been ablated in 62 patients by electric hook, and diversion was performed in 42 (42.85% cases. Data were analyzed by SPSS software version18.Findings: Totally 98 patients with mean age at diagnosis 62 (±13 days were included in this study. Fifty seven cases had been catheterized within one to 6 days of life (mean age one day, PUV was ablated in 62 patients by electric hook, and diversion was performed in 42 cases. The most common symptom in our group was dribbling poor stream 51% and urinary tract infection (UTI 40.8%. There was vesico-ureteral-reflux (VUR in 61.2%, and hydronephrosis in 82.6%. Most common associated anomaly was kidney anomalies (multicystic kidney disease and renal agenesis/dysplasia in 8 (8.2% patients. Twenty patients had prenatal diagnosis of PUV. Complication occurred in three (3.1% patients. Mortality occurred in 5 (5.1% patients. Mean follow-up period was 3.4±1.2 years (1.5 months to 5 years.Conclusion: Urinary drainage by feeding tube in early days of infancy, followed by valve ablation is the best treatment in PUV, and urinary diversion improves the outcome. VCUG is still the gold-standard imaging modality for documenting PUVs. The factors like renal dysplasia and UTI have their role in final outcome.

    Full Text Available Successful pregnancy outcome is an uncommon occurrence in women requiring chronic dialysis treatment. We reviewed the course and outcome of 9 pregnancies occurred in women on chronic hemodialysis in our center from 1999-2007; 5 of them ended with delivery of alive newborns, 2 with fetal deaths in-utero, and 2 with abortions. The average age of patients was 34 years. The etiology of the original kidney disease was unknown in 44.4% of the cases, and only 22.2% of the patients maintained diuresis. Dialysis started in 8 cases before the diagnosis of pregnancy. The average gestational age at diagnosis was 14 weeks. We modified the prescription of dialysis in 4 patients by increasing the frequency of the dialysis sessions to 6 per week and in 3 by increasing the duration of each session to 6 hours. Anemia was present in all the cases; 3 patients received erythropoietin and 4 patients required transfusion. The pregnancy was com-plicated in 44% of the cases by a polyhydramnios. The average time at delivery was 33 weeks and it was achieved in 80% of pregnancies through vaginal route. The average weight of newborns was to 2380 g. We conclude that pregnancy in women on hemodialysis is possible. The success of pregnancy may be influenced by the residual diuresis and early diagnosis to improve the quality of dialysis by increasing the dialysis dose.

    AIM: To determine the etiology and prognostic factors for neonatal gastric perforation(NGP), a rare but life-threatening disease.METHODS: Between 1980 and 2011, nine patients un-derwent surgical intervention for NGP at Seoul National University Children’s Hospital. The characteristics and prognosis of the patients were retrospectively analyzed.RESULTS: Among the nine patients, three(33.3%) were preterm babies and five(55.5%) had associated anomalies, which included diaphragmatic eventration(n = 2), congenital diaphragmatic hernia, esophageal atresia with tracheoesophageal fistula, and antral web. Three(33.3%) patients were born before 1990 and three(33.3%) had a birth weight < 2500 g. Pneumo-peritoneum was found on preoperative images in six(66.7%) patients, and incidentally in the other three(33.3%) patients. Surgery was performed within 24 h after the onset of symptoms in seven(77.8%) patients. The overall mortality rate was 22.2%(2/9). The time between symptoms and surgical intervention was the only prognostic factor for survival, whereas premature birth and birth weight were not.CONCLUSION: Early detection and advances in neo-natal intensive care may improve the prognosis of NGP.

    Introduction: The existing literature shows that mesh reinforcement improves the anatomical success rate of cystocele repair. We report the long-term results of a custom bell-shaped mesh with simultaneous urethral support for the repair of cystocele. Materials and Methods: The present study was a single-center, single-surgeon case series of 36 patients. Only patients with Pelvic Organ Prolapse Quantification system (POP-Q) stage 2 and above were included in the study. Patients having rectocele or uterine/vault prolapse were excluded. Body of the mesh was used for reinforcement of the cystocele repair and two limbs were left tension free in the retropubic space. Patients were followed 3 monthly for the first year and yearly thereafter. Recurrence was defined as cystocele ≥stage 2 (Aa or Ba 0) any time after the first follow-up. Results: Mean patient age was 58.5 ± 6.2 years. The mean parity was 3.2 ± 1.6. Of 36 patients, 11 (30.5%) of the patients were POPQ stage 2, 15 (41.7%) were stage 3 and 10 (27.7%) were stage 4 cystocele. The mean follow-up period was 53.4 months, with 32 patients reporting for follow-up till date (88.9%). There was no bladder injury, no mesh erosion or infection. No patient required CIC (clean intermittent catheterization) or had stress urinary incontinence post-operatively at 5 years of follow-up. Conclusion: The bell-shaped mesh is a simple, effective and safe procedure in the surgical management of cystocele with excellent long-term outcome. PMID:26604446

  7. Safety and effectiveness of the Genous™ endothelial progenitor cell-capture stent in the first year following ST-elevation acute myocardial infarction: A single center experience and review of the literature

    Purpose: The Genous™ stent (GS) is designed to accelerate endothelization, which is potentially useful in the pro-thrombotic environment of ST-elevation acute myocardial infarction (STEMI). We aimed to evaluate the safety and effectiveness of the GS in the first year following primary percutaneous coronary intervention (PCI) and to compare our results with the few previously published studies. Methods and Materials: All patients admitted to a single center due to STEMI that underwent primary PCI using exclusively GS, between May 2006 and January 2012, were enrolled. The primary study endpoints were major adverse cardiac events (MACEs), defined as the composite of cardiac death, acute myocardial infarction and target vessel revascularization, at one and 12 months. Results: In the cohort of 109 patients (73.4% male, 59 ± 12 years), 24.8% were diabetic. PCI was performed in 116 lesions with angiographic success in 99.1%, using 148 GS with median diameter of 3.00 mm (2.50–4.00) and median length of 15 mm (9–33). Cumulative MACEs were 2.8% at one month and 6.4% at 12 months. Three stent thromboses (2.8%), all subacute, and one stent restenosis (0.9%) occurred. These accounted for the four target vessel revascularizations (3.7%). At 12 months, 33.9% of patients were not on dual antiplatelet therapy. Conclusions: GS was safe and effective in the first year following primary PCI in STEMI, with an apparently safer profile comparing with the previously published data. Summary: We report the safety and effectiveness of the Genous™ stent (GS) in the first year following primary percutaneous coronary intervention in ST-elevation acute myocardial infarction. A comprehensive review of the few studies that have been published on this subject was included and some suggest a less safe profile of the GS. Our results and the critical review included may add information and reinforce the safety and effectiveness of the GS in ST-elevation in acute myocardial infarction

    Full Text Available Objective: Fecal diversion is often indicated in cases with fecal incontinence, Fournier’s gangrene, anal fistula, and inoperable obstructive anorectal cancer. Trephine colostomy can be performed without necessitating laparotomy. We present our experience related to the outcome of trephine sigmoid colostomy. Methods: The retrospective study included 14 patients who underwent trephine colostomy due to various conditions including Fournier’s gangrene, inoperable anorectal cancer, recto-vaginal fistula, and benign stricture due to radiotherapy at our clinic between January 2010 and January 2015. Results: Patients comprised 4 females and 10 males with a mean age of 52.07 years. The indications for stoma formation were Fournier’s gangrene in 7 cases, inoperable anorectal cancer in 5, rectovaginal fistula in 1, and benign stricture due to radiotherapy in 1 case. Eight patients underwent surgery under regional anesthesia. All the patients underwent trephine loop sigmoid colostomy. One patient had second operation on the postoperative period due to colostomy prolapse. The temporary stomas were closed in 3 months. Mean length of hospital stay was 14 days. Conclusion: Trephine stoma is a relatively simple, safe and rapid procedure and an effective alternative to colostomy formation without laparotomy indications. It can be performed under emergency or elective conditions with low morbidity. J Clin Exp Invest 2015; 6 (2: 87-90

    About 105 consecutive acute myeloid leukemia (AML) patients treated with the same induction-consolidation program between 2004 and 2013 were retrospectively analyzed. Median age was 47 years. The first induction course included fludarabine (Flu) and high-dose cytarabine (Ara-C) plus idarubicin (Ida), with or without gemtuzumab-ozogamicin (GO) 3 mg/m(2) (FLAI-5). Patients achieving complete remission (CR) received a second course without fludarabine but with higher dose of idarubicin. Patients not achieving CR received an intensified second course. Patients not scheduled for early allogeneic bone marrow transplantation (HSCT) where planned to receive at least two courses of consolidation therapy with Ara-C. Our double induction strategy significantly differs from described fludarabine-containing regimens, as patients achieving CR receive a second course without fludarabine, to avoid excess toxicity, and Ara-C consolidation is administrated at the reduced cumulative dose of 8 g/m(2) per cycle. Toxicity is a major concern in fludarabine containing induction, including the recent Medical Research Council AML15 fludarabine, cytarabine, idaraubicin and G-CSF (FLAG-Ida) arm, and, despite higher anti-leukemic efficacy, only a minority of patients is able to complete the full planned program. In this article, we show that our therapeutic program is generally well tolerated, as most patients were able to receive subsequent therapy at full dose and in a timely manner, with a 30-day mortality of 4.8%. The omission of fludarabine in the second course did not reduce efficacy, as a CR rate of 83% was achieved and 3-year disease-free survival and overall survival (OS) were 49.6% and 50.9%, respectively. Our experience shows that FLAI-5/Ara-C + Ida double induction followed by risk-oriented consolidation therapy can result in good overall outcome with acceptable toxicity. Am. J.

  12. Multidisciplinary treatment of Wilms' tumour. 13 years' experience

    The authors describe the results obtained by them personally in their multidisciplinary treatment of Wilms' tumour. In the National Paediatric Institute, Mexico City, 116 cases of Wilms' tumour in children were studied between January 1971 and December 1983. Of these, only 57 were evaluated as only they had completed their multidisciplinary treatment and had been followed up for over two years. Wilms' tumour is the solid abdominal tumour most frequently found in Mexican children. It is the fifth most frequent malign tumour after leukaemia, tumours of the central nervous system, Hodgkin's disease and non-Hodgkin's lymphomas, and retinoblastoma. The multidisciplinary treatment included: radical surgery; radiotherapy (site and dosage by group and by age of the child) and chemotherapy (drugs according to the group and histology of the tumour). In 82% of cases, the tumours occurred before the age of five, predominantly in girls. The average growth time was three months. Where tumour histology was favourable, 78% survived; 45% survived when the histology was adverse. For the various groups, survival was 100% in group I, 83.5% in group II, and 71.5% in group III and 25% in group IV. The survival of all groups was 67% and the actuarial survival was 83%. (author)

    2008-01-01

    Full Text Available We undertook this observational study to assess the incidence of acute rejections (AR in the first six months after transplantation at Al-Karama Hospital, Iraq. Sixty eight patients (49 males and 19 females underwent renal transplantation in 2006 and were followed up weekly. Forty six received kidneys from related donors and 22 from unrelated donors. During the first six months after transplantation AR occurred in 16 patients (23%; 11 (23% related and 5 (23% unrelated donor transplantation. We conclude that the incidence of acute rejection was similar in related and unrelated donor transplantation and the general incidence was comparable to that reported from most centers.

  14. Renal cell carcinoma in dialysis patients. A single center experience

    Renal cell carcinoma (RCC) is a life-threatening complication of end-stage renal disease with an unclear pathogenesis. We evaluated RCC developing in patients undergoing dialysis. In 2624 patients undergoing hemodialysis or continuous ambulatory peritoneal dialysis at our hospital between July 1993 and March 2004, we performed annual screening for RCC using abdominal computed tomography and ultrasonography. Patients diagnosed with RCC underwent radical nephrectomy as well as clinical and pathologic evaluation. RCC was detected in 44 patients (1.68%; 31 males and 13 females). The age of RCC patients was 55.5±11.1 years. Dialysis duration before RCC diagnosis was 11.2±7.2 years. Most RCC were early stage and low stage by TNM classification, 43 patients had N0M0 RCC, whereas one had N1M0. Tumor size was 2.9±1.9 cm. The predominant histological type of RCC was common or conventional cell-type carcinoma (clear cell carcinoma and granular cell carcinoma). Of patients, 5 (11.4%) had bilateral RCC, and satellite tumor lesions in RCC were detected in 13 (29.5%). In 36 patients (81.8%) RCC was accompanied by acquired cystic disease of the kidney. These patients had longer dialysis durations (P=0.01) and smaller tumors (P=0.048). RCC metastasized postoperatively in 4 patients (9.1%), while one (2.3%) died of cancer. Our dialysis patients showed a higher incidence of RCC than the general population. Prognosis was favorable because tumors were detected by screening when they were small. Therefore, periodical screening for RCC seems very important in dialysis patients. (author)

    2011-01-01

    Full Text Available Recent evidence highlights the relationship between metabolic syndrome (MS and increased risk of cardiovascular (CV diseases. The overall prevalence of the MS is increased in hemodialysis population. To evaluate the prevalence of the MS and obesity in our hemodialysis (HD patients, we studied 234 HD patients and 34 patients were excluded from the study due to incomplete data at the time of analysis. For the remaining 200 patients, 92% were below the age of 70 years old, 162 (81% were hypertensive, 90(45% were diabetic, 54 (27% had ischemic heart diseases, and 116 (58% had MS. The incidence of MS in the male and female patients was 50% and 67%, respectively, with a mean abdominal girth more than 94 cm in males and only 14% of the patients revealed abdominal girth measurement below 80 cm in females. We conclude that there is a high prevalence of obesity and MS in our HD patients. Such patients may be at risk of developing morbidities and may benefit from therapy such as lifestyle changes including weight reduction and increased physical activity.

Previous pelvic surgery (13, 29.5%, infertility treatment (11, 25%, and pelvic inflammatory disease (10, 22.7% were the common predisposing factors. Twenty-five (57% presented with ruptured EP and were operated within 24 h, and the remaining were kept under observation till further diagnosis. After confirming the diagnosis, 12/19 underwent laparoscopy, whereas 7/19 received medical treatment. Surgery confirmed fallopian tube pregnancies in 35 (94.5%. No mortality was observed. Conclusion: Previous pelvic surgeries were the major etiological factor for EP. Other factors were infertility treatment and pelvic inflammatory disease. The most common site of EP was fallopian tubes.

  18. Single Center Experience with the AngioVac Aspiration System

    PurposeThe AngioVac catheter system is a mechanical suction device designed for removal of intravascular material using extracorporeal veno-venous bypass circuit. The purpose of this study is to present the outcomes in patients treated with the AngioVac aspiration system and to discuss its efficacy in different vascular beds.Materials and MethodsA retrospectively review was performed of seven patients treated with AngioVac between October 2013 and December 2014. In 6/7 cases, the AngioVac cannula was inserted percutaneously and the patient was placed on veno-venous bypass. In one of the cases, the cannula was inserted directly into the Fontan circuit after sternotomy and the patient was maintained on cardiopulmonary bypass. Thrombus location included iliocaval (2), SVC (1), pulmonary arteries (1), Fontan circuit and Glenn shunt with pulmonary artery extension (1), right atrium (1), and IVC with renal vein extension (1).ResultsThe majority of thrombus (50–95 %) was removed in 5/7 cases, and partial thrombus removal (<50 %) was confirmed in 2/7 cases. Mean follow-up was 205 days (range 64–403 days). All patients were alive at latest follow-up. Minor complications included three neck hematomas in two total patients. No major complications occurred.ConclusionAngioVac is a useful tool for acute thrombus removal in the large vessels. The setup and substantial cost may limit its application in straightforward cases. More studies are needed to establish the utility of AngioVac in treatment of intravascular and intracardiac material

    Full Text Available Purpose: To determine the prevalence, outcome and prognostic factors in children with hemolytic uremic syndrome (HUS who underwent laparotomy. Materials and Methods: The medical records of 104 patients with HUS who presented to our center between 1986 and 2003 were reviewed retrospectively. Data were analyzed using Student′s t test for comparing means, Fisher′s exact test for frequencies and Pearson′s correlation for finding the correlations. Results: 78% of cases presented with vomiting and diarrhea. Seven out of 104 needed surgical exploration. The indications of surgery were acute abdomen, severe abdominal distention and the sign of peritonitis. The findings at laparotomy were intussusceptions, perforation (colon, ileum, gangrene of entire colon, rectosigmoidal tearing, duodenal obstruction and toxic megacolon. Pathological findings were transmural infarction in two cases in which staged surgical management was performed (cecostomy, resection, later anastomosis. Four out of seven patients died because of pulmonary failure, coma and multiple organ failure ( P< 0.05 compared to those who did not need laparotomy. The patients requiring surgery were young (< 3 years, had high leukocyte count (>20000 mm 3 and low albumin level (< 3g/dl ( P< 0.05. Conclusion: Surgical complications of HUS are rare but are assorted with high mortality due to respiratory failure and multiple organ failure. Early decision of laparotomy associated with intensive care, including mechanical ventilation, adequate dialysis and ultrafiltration, are recommended.

    2012-01-01

    Full Text Available Methanol is a cheap and potent adulterant of illicit liquors. Hemodialysis (HD is the best method to rapidly remove both toxic acid metabolites and parent alcohols, and it plays a fundamental role in treating severely poisoned patients. This retrospective study was carried out on 91 patients with detectable serum methanol levels who underwent HD. Because toxic alcohol levels were not immediately available, the initial diagnosis and treatment was based on clinical history with evidence of toxic alcohol intake, presence of high anion metabolic acidosis and/or end organ damage. Patients received bicarbonate, ethanol, according to clinical features and blood gases. Patients underwent HD in the setting of known methanol ingestion with high anion gap metabolic acidosis, or evidence of end-organ damage, regardless of methanol level. HD prescription included large surface area dialyzer (≥1.5 m2, blood flow rate of 250-350 mL/min and dialysate flow rate of 500 mL/min for 4-6 h. Between 9 and 11 July 2009, 91 males with mean age 40 ± 8.5 years underwent HD, and 13 patients required a second HD session. Patients consumed 100-500 mL illicit liquors, and symptoms appeared six and 60 h later. Clinical features were gastro-intestinal symptoms (83.5%, visual disturbances (60.4%, central nervous system symptoms (59.3% and dyspnea (43.9%. Before HD, mean pH was 7.11 ± 0.04 (range 6.70- 7.33 and mean bicarbonate levels were 8.5 ± 4.9 mmol/L (range 2-18. Three patients died due to methanol intoxication. Mortality was associated with severe metabolic acidosis (pH ≤ 6.90, ventilator requirement and coma/seizure on admission (P < 0.001. Timely HD, bicarbonate, ethanol and supportive therapy can be life-saving in methanol intoxication.

  4. Malaria induced acute renal failure: A single center experience

    Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, ou come and predictors of mortality in patients with malarial acute renal failure, we retrospectively studied the last two years records of malaria induced acute renal failure in patients with peripheral smear positive for malarial parasites. One hundred (10.4%) (63 males, 37 females) malaria induced acute renal failure amongst 958 cases of acute renal failure were evaluated. Plasmodium (P). falciparum was reported in 85%, P. vivax in 2%, and both in 13% patients. The mean serum creatinine was 9.2 ± 4.2 mg%, and oligo/anuria was present in 82%; 78% of the patients required hemodialysis. Sixty four percent of the patients recovered completely, 10% incompletely, and 5% developed chronic kidney failure; mortality occurred in 21% of the patients. Low hemoglobin, oligo/anuria on admission, hyperbilirubinemia, cerebral malaria, disseminated intravascular coagulation, and high serum creatinine were the main predictors of mortality. We conclude that malaria is associated with acute renal failure, which occurs most commonly in plasmodium falciparum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function (Author).

    2013-03-27

    Portal hypertensive biliopathy (PHB) is characterized by anatomical and functional abnormalities of the intrahepatic, extrahepatic and pancreatic ducts, in patients with portal hypertension associated to extrahepatic portal vein obstruction and less frequently to cirrhosis. These morphological changes, consisting in dilatation and stenosis of the biliary tree, are due to extensive venous collaterals occurring in an attempt to decompress the portal venous blockage. It is usually asymptomatic until it progresses to more advanced stages with cholestasis, jaundice, biliary sludge, gallstones, cholangitis and finally biliary cirrhosis. Imaging modalities of the biliary tree such as Doppler ultrasound, computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are essential to establish the diagnosis and the need of therapeutical interventions. Once the diagnosis is established, treatment with ursodesoxycholic acid seems to be beneficial. Decompression of the biliary tree to dilate, remove stones or implant biliary prosthesis by endoscopic or surgical procedures (hepato-yeyunostomy) usually resolves the cholestatic picture and prevents septic complications. The ideal treatment is the decompression of the portal system, with transjugular intrahepatic porto-systemic shunt or a surgical porto-systemic shunt. Unfortunately, few patients will be candidates for these procedures due to the extension of the thrombotic process. The purpose of this paper is to report the first 3 cases of PHB seen in a Colombian center and to review the literature. PMID:23556047

    2012-01-01

    Full Text Available Objectives: There is paucity of information regarding clinical profile of hypopituitarism from India. We report the clinical profile of hypopituitarism from a tertiary center in North India. Materials and Methods: This study was carried out in patients attending our endocrine center between January 2010 and December 2011. All new patients were studied prospectively and those registered before January 2010 retrospectively. Relevant clinical, hormonal, and imaging data were collected. Dynamic testing for pituitary functions was carried out as necessary. Hormonal deficiencies were defined as per prevailing recommendations. Results: This study included 113 subjects. The mean age was 38.6 ± 17.8 years (range, 4 - 76 years. There were 78 (69% males and 35 females (31%. There were 22 subjects aged ≤18 years (childhood and adolescence and 91 adults (>18 years. Visual disturbances were the most common presenting complaint (33%, though headache was the most common symptom (81%. Fifteen percent presented with pituitary apoplexy. Tumors comprised of 84% of cases. Hypogonadism (97% was the most common abnormality seen followed by hypothyroidism (83.2%, hypoadrenalism (79.6%, growth hormone deficiency (88.1% of the 42 patients tested, and diabetes insipidus (13.3%. Panhypopituitarism was seen in 104 (92% patients. There were no cases of hypopituitarism secondary to traumatic brain injury, subarachnoid hemorrhage, central nervous system infections, or cranial irradiation to extrasellar tumors. Conclusion: The most common cause of hypopituitarism at tertiary care center is pituitary tumors and the commonest presenting complaint is visual symptoms. Panhypopituitarism is present in 92% cases.

  7. Treatment of hepatocellular carcinoma: A single-center experience

    Purpose. The comparative efficacy of transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the treatment of hepatocellular carcinoma (HCC) was investigated. Methods. Two hundred and sixty consecutive patients were retrospectively analyzed: 156 had received between one and six chemoembolization sessions at 3-month intervals, 33 had had PEI, and the remaining 71 patients refused any treatment. The follow-up ranged from 3 to 36 months. Survival rates were statistically analyzed by life-table analysis. Results. Patients' survival was affected by the number of nodules and by the Child's and Okuda's classes; no relationship was found between survival rates and the histologic grade or vascular supply of the tumor. In the case of a single lesion of Okuda's class I, TACE was more effective than PEI. In multifocal HCC, TACE was better than no treatment in Okuda's class I and Child's class A. Conclusion. We suggest TACE as the treatment of choice in Child A or Okuda I patients with multifocal HCCs; it seems of little help in Child B-C or Okuda II-III patients

    Full Text Available  Introduction: Transcatheter closure is a treatment choice for the most children with patent ductus arteriosus (PDA. The closure of the ductus is indicated in any child or adolescent with developed symptoms of significant L-R shunt. The aim of this article is to present our results in 5 years treatment of patients with PDA and their outcome. Methods: From 2009 to 2014, 30 patients underwent a transcatheter closure of PDA at Centre for Heart and Pediatric clinic of Clinical University Centre of Sarajevo. Aortic angiogram was performed to evaluate the size, position, and shape of the duct for selection of appropriate occluder device type and size. All procedures were performed by local team of cardiologists from the Department of Cardiology, Pediatric clinic, with invasive cardiologists team from Sweden and Austria. Echocardiography was repeated at intervals of 24 hours, then 1month, 3 months, and 1 year after the procedure to assess the outcome. Results: Thirty patients underwent transcatheter closure of PDA during the study period. PDA of ≤ 2.0 mm was present in 8 patients and they underwent PDA closure with coils, while 22 patients had PDA diameter  ≥ 2 mm, and they were treated by Amplatzer duct occluder (ADO. Only in 2 (6.2% patients complications have been observed. The length of hospital stay after the treatment was two to three days. Conclusion: Transcatheter closure of PDA is a modern, safe and efficient method that ensures a faster recovery of the patients, shortens the length of hospitalization.

    2014-02-01

    Results: One of our 105 patients with BD was found to have solid tumor in the rate of 0.9 %. The remaining 104 patients with BD were in follow up without any malignancy in this period. The malignancy that we reported was invasive right breast carcinoma in a 55-year-old woman with BD. A radically modified right mastectomy and axillary lymphadenectomy were performed and postoperative doxorubicin, cyclophosphamide therapy for four cycles and hormonal therapy with tamoxifen and leuprolide acetate was administered as adjuvant therapy. This patient had a history of 16 years colchicine usage as medication for BD. Conclusion:The rheumatologic diseases can predispose malignancy, the autoimmune nature of BD or the immunosupressive medicines could be possible causes of this carcinoma. However, in our study only one patient had malignancy. The another point of view; management and also prevention of cancer with BD is important entity.

  13. A Single-Center 7-Year Experience with End-Stage Renal Disease Care in Nigeria—A Surrogate for the Poor State of ESRD Care in Nigeria and Other Sub-Saharan African Countries: Advocacy for a Global Fund for ESRD Care Program in Sub-Saharan African Countries

    Datonye Dennis Alasia

    2012-01-01

    Full Text Available Background. A single-center ESRD care experience in a Nigerian teaching hospital is presented as a surrogate case to demonstrate the prevailing ESRD care situation in Nigeria and most SSA countries. Methods. The data of 320 consecutive ESRD patients undergoing maintenance haemodialysis treatment during a seven-year period were retrospectively analyzed. Results. Over 80% of the subjects funded dialysis treatments from direct out of pocket payment. The mean duration on dialysis before dropout was 5.2±7.6 weeks, with majority 314 (98.1% of the patients unable to sustain dialysis above 12 weeks. Total dialysis sessions during the 7-year period was 1476 giving an average weekly dialysis session of 0.013 (0.05 hour/week per patient per week. One hundred and twenty-eight (40% patients died within 90 days of entry into dialysis care. Conclusions. ESRD care in this single centre was characterized by gross dialysis inadequacy and case fatality due to the inability to access and afford care. The opportunities for kidney transplantation are also very low. Poverty and the absence of government support for ESRD care are responsible for the poor outcomes. A global focus on ESRD care in SSA countries has thus become imperative.

    Endometrial cancer is the third most common gynecologic cancer in the Korea and occurs mainly in menopausal women. Although it can develop in young premenopausal women cancer as well, an attack in the adolescent girl is very rare. A 13-year-old girl visited gynecology department with the complaint of abnormal uterine bleeding. An endometrial biopsy revealed FIGO (International Federation of Gynecology and Obstetrics) grade II endometrial adenocarcinoma. In the treatment of endometrial cancer, conservative management should be considered if the patient is nulliparous or wants the fertility preservation. Therefore, we decided to perform a hormonal therapy and a follow-up endometrial biopsy after progestin administration for eight months revealed no residual tumor. We report a case of endometrial cancer occurred in a 13-year-old girl with a brief review of the literature. PMID:27004208

    Pleural mesothelioma is an uncommon tumor in all age groups, but is especially rare in childhood. We describe the clinical and radiological features of malignant pleural mesothelioma in a 13-year-old girl. The chest radiograph showed nearly complete opacification and loss of volume in the left hemithorax. Computed tomography demonstrated a large pleural effusion centrally surrounded by a thick enhancing rind of soft tissue. The radiological features of childhood pleural mesothelioma in our case were similar to those described in adults with this disease. (orig.)

  19. Global Ammonia Concentrations Seen by the 13-years AIRS Measurements

    Warner, Juying; Wei, Zigang; Larrabee Strow, L.; Dickerson, Russell; Nowak, John; Wang, Yuxuan

    2016-04-01

    Ammonia is an integral part of the nitrogen cycle and is projected to be the largest single contributor to each of acidification, eutrophication and secondary particulate matter in Europe by 2020 (Sutton et al., 2008). The impacts of NH3 also include: aerosol production affecting global radiative forcing, increases in emissions of the greenhouse gases nitrous oxide (N2O) and methane (CH4), and modification of the transport and deposition patterns of SO2 and NOx. Therefore, monitoring NH3 global distribution of sources is vitally important to human health with respect to both air and water quality and climate change. We have developed new daily and global ammonia (NH3) products from AIRS hyperspectral measurements. These products add value to AIRS's existing products that have made significant contributions to weather forecasts, climate studies, and air quality monitoring. With longer than 13 years of data records, these measurements have been used not only for daily monitoring purposes but also for inter-annual variability and short-term trend studies. We will discuss the global NH3 emission sources from biogenic and anthropogenic activities over many emission regions captured by AIRS. We will focus their variability in the last 13 years.

    Full Text Available Background/objectives: Congenital hypothyroidism is one of the most common preventable causes of mental retardation in children. The prognosis of infants detected by neonatal screening and started on treatment early is excellent, with intelligence quotients similar to sibling or classmate without the disease. Setting: Department of ENT, Head and Neck Surgery, KVG Medical College, Sullia. 1Case report: A 15 year old boy came with history of head ache, generalized body ache and lack of concentration in school. He was a case of congenital hypothyroidism and was on irregular treatment for the last 13 years. Intervention: The patient was advised strictly to continue the oral l-thyroxine 100μg one hour before food and come for regular follow-up. Conclusion: Definite intellectual deterioration is seen if oral l-thyroxine is not started within 50 days of life and the deterioration is irreversible. So in India newborn screening programs should be implemented as a national program as it is very important to diagnose and treatcongenital hypothyroidism as soon as possible and to treat it effectively.

    Full Text Available OBJECTIVE: To analyze drug use trends among college students in 1996, 2001 and 2009. METHODS: A cross-sectional epidemiological study with a multistage stratified cluster sample with 9,974 college students was conducted in the city of São Paulo, southeastern Brazil. An anonymous self-administered questionnaire was used to collect information on drug use assessed in lifetime, the preceding 12 months and the preceding 30 days. The Bonferroni correction was used for multiple comparisons of drug use rates between surveys. RESULTS: There were changes in the lifetime use of tobacco and some other drugs (hallucinogens [6.1% to 8.8%], amphetamines [4.6% to 8.7%], and tranquilizers [5.7% to 8.2%] from 1996 to 2009. Differences in the use of other drugs over the 12 months preceding the survey were also seen: reduced use of inhalants [9.0% to 4.8%] and increased use of amphetamines [2.4% to 4.8%]. There was a reduction in alcohol [72.9% to 62.1%], tobacco [21.3% to 17.2%] and marijuana [15.0% to 11.5%] use and an increase in amphetamine use [1.9% to 3.3%] in the preceeding 30 days. CONCLUSIONS: Over the 13-year study period, there was an increase in lifetime use of tobacco, hallucinogens, amphetamines, and tranquilizers. There was an increase in amphetamine use and a reduction in alcohol use during the preceding 12 months. There was an increase in amphetamine use during the preceding 30 days.

  4. Multi drug resistance tuberculosis: pattern seen in last 13 years

    Background: Drug resistance in tuberculosis is a serious problem throughout the world especially, after the emergence of multi drug resistant TB strains. Objectives: To estimate drug resistance in TB patients and compare it with previous studies to see the changing trends. Materials and Methods: The PMRC Research Centre receives sputum samples from all the leading hospitals of Lahore. This retrospective analysis was done from 1996 to 2008 on the multi drug resistant TB strains that were seen during these years. Five first lines anti tuberculosis drugs were tested on Lowenstein Jensen medium using standard proportion method. Results: A total of 2661 confirmed isolates of Mycobacterium tuberculosis were seen over the past 13 years. Of the total, 2182 were pulmonary and 479 were extra pulmonary specimens. The patients comprised of those with and without history of previous treatment. These specimens were subjected to drug susceptibility testing. Almost half of the patient had some resistance; multiple drug resistance was seen in 12.3% and 23.0% cases without and with history of previous treatment respectively. Overall resistance to rifampicin was 26.4%, isoniazid 24.1% streptomycin 21.6% ethambutol 13.4% and pyrazinamide 28.4% respectively. Statistically significant difference was seen between primary and acquired resistance. When compared with the reports from previous studies from the same area, there was a trend of gradual increase of drug resistance. Conclusions Resistance to anti tuberculosis drugs is high. Policy message. TB Control Program should start 'DOTS Plus' schemes for which drug susceptibility testing facilities should be available for correctly managing the patients. (author)

    Purpose: To analyse the management and clinical outcome of patients treated for retroperitoneal soft tissue sarcoma and to identify prognosis factors. Patients and method: This is a retrospective study of 20 adults; 11 women and nine men treated between 1980 and 2000 in our institution. Results: There were seven lipo sarcomas and 13 leiomyo-sarcomas. The mean tumor size was 26 cm. Three patients underwent a complete resection (R0), 14 patients an incomplete resection (R1/R2) with microscopic or macroscopic tumour remained after surgery. Only three patients had a surgical biopsy. Median follow-up was 18 months. Overall survival rates was 45%, 10% at two and five years, respectively. Among the following factors, sex, age, symptom duration, tumor size, histologic type, histologic grade, resection type, mitotic index, necrosis extension, histologic differentiation, and A.J.C.C. stage, only mitotic index factor (scale 1,2 versus scale 3) significantly influenced patient survival (p = 0.02). Conclusion: This study re-emphasizes the poor outcome of patients with retroperitoneal sarcoma. Survival rates appeared low when compared with other studies. These results incite for a more aggressive approach. (authors)

  11. Impact of aprotinin and renal function on mortality: a retrospective single center analysis

    Von Visger Jon

    2011-08-01

    Full Text Available Abstract Background An estimated up to 7% of high-risk cardiac surgery patients return to the operating room for bleeding. Aprotinin was used extensively as an antifibrinolytic agent in cardiac surgery patients for over 15 years and it showed efficacy in reducing bleeding. Aprotinin was removed from the market by the U.S. Food and Drug Administration after a large prospective, randomized clinical trial documented an increased mortality risk associated with the drug. Further debate arose when a meta-analysis of 211 randomized controlled trials showed no risk of renal failure or death associated with aprotinin. However, only patients with normal kidney function have been studied. Methods In this study, we look at a single center clinical trial using patients with varying degrees of baseline kidney function to answer the question: Does aprotinin increase odds of death given varying levels of preoperative kidney dysfunction? Results Based on our model, aprotinin use was associated with a 3.8-fold increase in odds of death one year later compared to no aprotinin use with p-value = 0.0018, regardless of level of preoperative kidney dysfunction after adjusting for other perioperative variables. Conclusions Lessons learned from our experience using aprotinin in the perioperative setting as an antifibrinolytic during open cardiac surgery should guide us in testing future antifibrinolytic drugs for not only efficacy of preventing bleeding, but for overall safety to the whole organism using long-term clinical outcome studies, including those with varying degree of baseline kidney function.

  16. Climatology of monsoon precipitation over the Tibetan Plateau from 13-year TRMM observations

    Aijuan, Bai; Guoping, Li

    2015-07-01

    Based on the 13-year data from the Tropical Rainfall Measuring Mission (TRMM) satellite during 2001-2013, the influencing geographical location of the Tibetan Plateau (Plateau) monsoon is determined. It is found that the domain of the Plateau monsoon is bounded by the latitude between 27° N and 37° N and the longitude between 60° E and 103° E. According to the annual relative precipitation, the Plateau monsoon can be divided into three sections: the Plateau winter monsoon (PWM) over Iran and Afghanistan, the Plateau summer monsoon (PSM) over the central Plateau, and the transiting zone of the Plateau monsoon (TPM) over the south, west, and east edges of the Plateau. In PWM and PSM, the monsoon climatology has a shorter rainy season with the mean annual rainfall of less than 800 mm. In TPM, it has a longer rainy season with the mean annual rainfall of more than 1800 mm. PWM experiences a single-peak monthly rainfall with the peak during January to March; PSM usually undergoes a multi-peak pattern with peaks in the warm season; TPM presents a double-peak pattern, with a strong peak in late spring to early summer and a secondary peak in autumn. The Plateau monsoon also characterizes an asymmetrical seasonal advance of the rain belt. In the east of the Plateau, the rain belt migrates in a south-north orientation under the impact of the tropical and subtropical systems' oscillation. In the west of the Plateau, the rain belt advances in an east-west direction, which is mainly controlled by the regional Plateau monsoon.

  17. How to organize a neutron imaging user lab? 13 years of experience at PSI, CH

    Lehmann, E. H.; Vontobel, P.; Frei, G.; Kuehne, G.; Kaestner, A.

    2011-09-01

    PSI has a relatively long tradition in neutron imaging since the first trials were done at its formerly existing research reactor SAPHIR with film methods. This reactor source was replaced after its shutdown in 1994 by the spallation neutron source SINQ in 1996, driven by the 590 MeV cyclotron for protons with presently up to 2.3 mA beam current. One of the first experimental devices at SINQ was the thermal neutron imaging facility NEUTRA, which was designed from scratch and has been the first device of its kind at a spallation source. Until now, NEUTRA has been successfully in use for many investigations in a wide range of studies covering fuel cell research, environmental behavior of plants, nuclear fuel inspection and the research on cultural heritage objects. It has been the host of PhD projects for students from all over Europe for years. In a previous meeting it has been offered as a European reference facility. Some of its features were really adapted to the layout of new installations. In 2004, it was possible to initiate the project of a second beam line at SINQ for imaging with cold neutrons. Previous studies have shown the potential of this option in order to broaden the user profile and to extend the scientific basis for neutron imaging. It was inaugurated with a workshop at PSI in 2005. The user service was started at the facility ICON in 2006. Beside the setup, installation and optimization of the facilities, the organization of the user program plays an important role. The two neutron imaging beam lines are equal installations at SINQ among the 14 scientific devices. Therefore, the user approach is organized via "calls for proposals", which are sent out each half year via the "Digital User Office (DUO)" (see http://duo.web.psi.ch). The evaluation of the proposals is done by the "Advisory Committee for Neutron Imaging (ACNI)" consisting of 6 external and PSI internal members. Further requests are given by industrial collaborations. This beam time allocation is handled more directly and in time in order to fulfill the companies' demands. Here, the confidentiality plays a more important role than in scientific studies that are done with the aim of a free publication. It has been possible to earn money regularly from the industrial projects in order to cover the salary cost of some positions within the NIAG group. The permanent improvement of the methodology and performance in neutron imaging is a third major activity of the NIAG team. Running projects in this direction are the permanent insert of a grating interferometry device, improved energy selection with the help of single graphite crystals and utilization of the beam line BOA at SINQ for the energy range between 4 and 15 Å.

    2008-01-01

    Full Text Available Abstract Background Adenocarcinoma of the small bowel is a relatively rare malignancy as compared to the other malignancies of the gastrointestinal tract. Nonspecific presentation and infrequent occurrence often leads to a delay in diagnosis and consequent poor prognosis. Various other factors are of prognostic importance while managing these tumors. Methods The medical records of a total of 27 patients treated for adenocarcinoma of the small bowel at Providence Hospital and Medical Centers from year 1990 through 2003 were reviewed retrospectively. Data were analyzed using SPSS software (version 10.0; SPSS, Inc., Chicago, IL. Survival analyses were calculated using the Kaplan Meier method with the log rank test to assess the statistical significance. The socio-demographics (age, gender were calculated using frequency analyses. Results The patients included nine males and eighteen females with a median age at diagnosis of 62 years. Only 48% of the patients had an accurate preoperative diagnosis while another 33% had a diagnosis suspicious of small bowel malignancy. None of the patients presented in stage 1. The cumulative five-year survival was 30% while the median survival was 3.3 years. There was no 30-day mortality in the postoperative period in our series. Conclusion The univariate analysis demonstrated that tumor grade, stage at presentation, lymph nodal metastasis and resection margins were significant predictors of survival.

    Full Text Available Objectives: Atrial fibrillation (AF, the most common arrhythmia in clinical practice, is a major cause of stroke. Atrial fibrillation increases morbidity and mortality. Nowadays cryoablation therapy is being performed efficiently and safely worldwide. In this paper the clinical outcomes of the patients whom were treated with cryoablation were discussed. Methods: Between June 2012 and March 2014, patients with paroxysmal AF who were treated with cryoablation were included in the study. The medical records of the patients were retrospectively reviewed. Patients were called to receive information about the symptom recurrence. Results: Twelve patients were included in the study. Half of the patients were female. The mean age was 48 ± 15 years. Acute procedural success rate of cryoablation was 100%. In one patient transient right phrenic nerve injury occurred which was returned to normal after discontinuation of cryoablation therapy. One patient developed AF episode for 10 minutes in the 4th month of follow-up period. Conclusion: In patients with paroxysmal atrial fibrillation cryoablation effectively decrease symptoms consistent with the literature. J Clin Exp Invest 2014; 5 (4: 599-603

    2014-12-01

    Full Text Available Objective: To show etiology, diagnostic methods, and treatment options of patients with severe pericardial effusion determined after echocardiography. Methods: In this study, we retrospectively analyzed etiology, diagnosis and treatment options of 43 patients with severe pericardial effusions (i.e. effusions more than 20 mm either in front of the right ventricle or posterior to left ventricle as assessed by transthoracic echocardiography. The pericardiocentesis procedures were performed via subxiphoid approach. Glucose, protein, lactate dehydrogenase levels, polymerase chain reaction for tuberculosis, cytological, microbiological examinations and cultures were obtained from pericardial fluid. Results: Cardiac tamponade was diagnosed in 23 patients (54% and pericardiocentesis was immediately performed in these cases. Twenty patients who were unresponsive to empirical treatment, underwent pericardiocentesis to evaluate etiology and treatment.. Pericardial fluid was found to be exudate in 36 patients (83.7% and transudate in 7 patients (16.2%. The most common causes were malignancy (26%, and uremia (16% while idiopathic cases constituted 23% of the patient group. While malignant pericardial effusion was more common in males, idiopathic etiology and uremia were more common in female patients. Conclusion: Pericardiocentesis is the gold standard for clarifying the etiology and is also a lifesaving measure for cardiac tamponade. Delineating the specific etiology is particularly important for cases that do not respond to empirical treatment. A thorough history and physical examination, together with pericardiocentesis in selected cases will enable the accurate diagnosis of specific etiology and starting the treatment for this etiology.

    2015-12-01

    Full Text Available Background and Design: Occupational contact dermatitis (OCD is responsible for 80-90% of the occupational dermatoses. The aim of this work was to evaluate the clinical features of patients with OCD admitted to our hospital. Materials and Methods: The records of patients, who were admitted to our hospital with OCD between December 2009 and January 2013, were evaluated retrospectively. One hundred fifty-nine patients, who were diagnosed with OCD according to the Mathias criteria, were included in the study. Age, sex, location of the lesions, atopic status, glove use, occupational exposure time and total IgE levels of the patients were assessed. Patients with positive allergic reaction with "European Standard Series Skin Patch Test" were identified as allergic OCD and patients with negative test results as "irritant OCD". The clinical features and patch results of patients are evaluated. Results: One hundred fifty-nine patients with a mean age of 39±7.9 years consisted of 151 men and 8 women. The hands were the most common site of OCD; the palms were the most common affected areas of hand eczema. Eighty-one patients (50.1% were identified to have allergic OCD and 78 (49.9% as irritant OCD. Irritant OCD was most commonly seen in dental technicians, whereas allergic OCD was most commonly seen in tailors. The top 3 most frequent allergens were potassium dichromate (15.1%, nickel sulfate (9.11% and cobalt chloride (10.7%. Conclusion: In our country, there has been no comprehensive study presenting the clinical and descriptive characteristics of OCD. For preventing OCD and reducing sick leave we need to have data that belong to our country. Consequently, multicenter studies should be performed for establishing our own database on OCD.

    Objective To evaluate the efficacy and safety of bortezomib-based chemotherapy for 80 patients with multiple myeloma(MM).Methods A total of 80 cases with a median age of 57(range:25-78)years were enrolled in the study.Bortezomib-based regimens included VD(bortezomib and dexamethasone)and PAD(bortezomib,doxorubicin and dexamethasone).16 of the 80 patients

  13. Temporary Placement of Stent Grafts in Postsurgical Benign Biliary Strictures: a Single Center Experience

    To evaluate the effect of temporary stent graft placement in the treatment of benign anastomotic biliary strictures. Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patients had strictures following a liver transplantation; three of them in bilio-enteric anastomoses and one in a choledocho-choledochostomy. Four of the other five patients had strictures at bilio-enteric anastomoses, which developed after complications following laparoscopic cholecystectomies and in one after a Whipple procedure for duodenal carcinoma. In eight patients, balloon-expandable stent-grafts were placed and one patient was treated by insertion of a self-expanding stent-graft. In the transplant group, treatment of patients with bilio-enteric anastomoses was unsuccessful (mean stent duration, 30 days). The patient treated for stenosis in the choledocho-choledochostomy responded well to consecutive self-expanding stent-graft placement (total placement duration, 112 days). All patients with bilio-enteric anastomoses in the non-transplant group were treated successfully with stent-grafts (mean placement duration, 37 days). Treatment of benign biliary strictures with temporary placement of stent-grafts has a positive effect, but is less successful in patients with strictures developed following a liver transplant.

  14. Parathyroid Gland Function in Kidney Transplanted Patient: A single Center Experience

    2012-06-01

    Full Text Available Introduction: Information on the time course of serum parathormone levels after renal transplantation is scanty. Both the abrupt cessation of calcium-containing phosphorus binders and vitamin D (analogs at the time of surgery and the recovery of renal function may be hypothesized to affect parathyroid gland. This study firstly examined frequency distribution of various biochemical parameters such as alkaline phosphatase (ALP, phosphorus (P, intact parathormone (iPTH and calcium (Ca in renal transplanted patients and secondly examined the relationship between these parameters and various demographic data of renal transplanted recipients. Material and Methods: we studied 72 renal transplanted patients (47 men and 25 women with mean ages of 44 ± 12 years and mean body mass index of 24.2 ± 3.9. Serum Ca, P, ALP and serum iPTH were measured. Results: In this study, mean serum Ca and iPTH were 9.5 ± 0.7mg/dL and18.4 ± 8.2 Pg/mL (median=16.5. Mean serum ALP was 169 ± 133 IU/L (median=131. In this study, there was a negative relationship between serum iPTH and creatinine clearance (r=-0.44 P 0.05. There were inverse correlations of serum ALP with age (r=-0.35 P= 0.02 and duration of kidney transplantation (r=-0.29 P= 0.01. Conclusions: In contrast to previous findings, in this group of patients, there was not secondary hyperparathyroism or significantly increased bone activity. The results showed suppressed parathormone secretion. The reason may be due to excessive intake of calcium and Vitamin D analogues, which suppress the parathyroid gland, and may prone these patients to adynamic bone disease.

    Full Text Available Objective: Non-Hodgkin’s lymphoma (NHL of bone is a rare entity. The most common histological subtype is diffuse large B cell lymphoma (DLBCL. The major presenting symptoms are soft tissue swelling, bone pain and pathological fracture. Treatment options are chemotherapy, radiotherapy, surgery, or a combination of these modalities. Materials and Methods: We retrospectively analyzed the 18 patients (11 females, 7 males with NHL of bone who were diagnosed and treated between 1995-2005. The median age was 56.5 years. The median duration of symptoms was 4.5 months. The bone pain was the first symptom in all patients. Tru-cut biopsy was performed for diagnosis in most of the cases. Diagnosis in five patients (27.8% required open biopsy. Results: DLBCL (77.8% was the most common histological type among all patients. Other histological subtypes were anaplastic large cell lymphoma (11.1%, Burkitt-like lymphoma (5.6% and marginal zone lymphoma (5.6%. According to Ann Arbor staging system, 44.4% of patients were Stage I, 11.1% were Stage II and 44.4% were Stage IV. Bone marrow involvement was determined in four patients (22.2%. All patients except one were treated with anthracycline-containing regimens and eight patients (44.4% received rituximab combination with chemotherapy. Radiation therapy was performed as the first-line therapy in 9 (50% patients. The median follow-up was 37 months (range, 2-124 months. Among the 17 patients who achieved complete remission, five (27.8% relapsed. All patients were still alive. The five-year relapse-free survival was 73.5%.Conclusion: The treatment of bone lymphoma can be planned according to the stage and location of the disease. Although we had a relatively low number of patients, it could be concluded that whether or not radiation therapy is performed, rituximab in combination with systemic chemotherapy has been proven beneficial on survival.

  17. Elastographic assessment of liver fibrosis in children: A prospective single center experience

    Background: The assessment of liver damage in various disease states relies on a combination of clinical findings, biochemical parameters and invasive tests such as liver biopsy. The ultrasound elastography has emerged as a potential alternative test, providing quantifiable information on the elasticity/stiffness of the examined-tissues. We assessed the performance of ultrasound elastography using real-time Acoustic Radiation Force Imaging (ARFI) technology in evaluating the degree of liver fibrosis in children with and without liver disease. Methods: Children aged 0–18 years, hospitalized in the Emergency Clinical County Hospital Tg. Mures, Romania, between September 15, 2010 and January 15, 2011, were eligible for the study. Four groups were recruited as follow: patients with liver disease in the setting of various malignant disorders, children with non-malignant liver disease, overweight and obese children and healthy controls. The liver tissue elasticity was assessed in each individual using Shear Wave Velocity (SWV). Biochemical tests included transaminase levels. 19 children with chronic liver disease underwent biopsies. SWV was measured globally and separately for the liver-segments 1 and 8. Correlations between the SWV and laboratory test were established using non-parametric Spearman correlation test. Results: A total of 103 children underwent liver ultrasound elastographic assessments. Of these, 39 had malignancies, 19 had various chronic liver diseases, 13 had nonalcoholic fatty liver disease (NAFLD), and 32 were healthy controls. The transaminase values differed significantly between children with liver diseases and controls. In normal controls SWV values in the 1st segment were significantly lower compared to those in the in 8th segment of the liver (p = 0.0216). In the group with hepatic steatosis, the SWV values were statistically higher compared to those in healthy controls. Positive statistical correlations have been established between AST and SWV in the group of children with NAFLD and those with malignancies (p = 0.0032, p = 0.0045). Conclusions: Quantification of liver fibrosis by ARFI method correlates with the histological fibrosis stage in children with chronic liver disease and NAFLD. Clinical applications of this method in the diagnosis of pediatric liver disease deserve further study.

  1. Clinical Characteristics and Outcomes for Solitary Fibrous Tumor (SFT: A Single Center Experience.

    Nicholas DeVito

    Full Text Available Solitary fibrous tumor (SFT is a mesenchymal neoplasm of fibrous origin. The 2013 WHO classification of soft tissue tumors defines malignant forms as hypercellular, mitotically active (>4 mitosis/10 high-power fields, with cytological atypia, tumor necrosis, and/or infiltrative margins. With an IRB-approved protocol, we investigated patient records and clinicopathologic data from our Sarcoma Database to describe the clinical characteristics of both benign and malignant SFT. All pathology specimens were reviewed by two pathologists. Descriptive statistics and univariate/multivariate survival analysis were performed. Patient records and Social Security Death Index were used to evaluate vital status. Of 82 patients, 47 (57% were women and 73 (89% were Caucasian. Median age was 62 years (range, 20 to 89. Thirty-two (39% patients succumbed to the disease. Primary tumor site was lung/pleura in 28 (34%, abdomen/pelvis in 23 (28%, extremity in 13 (16%, and head/neck in 9 (11% patients. Pathology was described as benign in 42 (51% and malignant in 40 (49% patients. Compared to benign SFT, malignant histology is associated with larger tumor size, higher mitotic counts, metastatic disease at diagnosis, and greater use of chemotherapy and radiation therapy. Gender, age, and tumor site were not significantly different between benign and malignant subtypes. By univariate analysis, only benign vs. malignant variant and complete resection positively impacted overall survival (P = 0.02 and P<0.0001, respectively. In the multivariable analysis of overall survival, receiving chemotherapy or not receiving surgery were two variables significantly associated with higher failure rate in overall survival: patients with chemotherapy vs. no chemotherapy (P = 0.003, HR = 4.55, with 95% CI: 1.68-12.34 and patients without surgery vs. with surgery (P = 0.005, HR = 25.49, with 95% CI: 2.62-247.57. Clear survival differences exist between benign and malignant SFT. While surgery appears to be the best treatment option for benign and malignant SFT, better systemic therapies are needed to improve outcomes of patients with metastatic, malignant SFT.

    2015-03-01

    Full Text Available Objective: Primary liver cancer is one of the most common and lethal type of tumors in the world. Hepatocellular forms compose about 80% of all primary liver tumors. Our aim is to evaluate the patients with hepatocellular carcinoma admitted to our clinic retrospectively. Methods: First we identified viral hepatitis serology and whether antiviral treatment was administered before the diagnosis and the period until the development of hepatocellular carcinoma for each case with hepatocellular carcinoma. Child-Pugh stage in cirrhotic cases, the stage of viral hepatitis in non-cirrhotic cases, and the treatment method suggested for hepatocellular carcinoma and the average life expectancy (for the patients whose life expectancy is known were evaluated. Alpha-feto protein levels and computerized tomography, ultrasound, magnetic resonance imaging findings were evaluated retrospectively. Correlation between alpha-feto protein levels and tumor numbers were evaluated statistically. Results: Total of 69 patients were evaluated. The median age at presentation was 62.8 (ranging from 25 to 80 years. Median (overall survival OS was 7.0 (ranging from 0 to 145 months in all patients. 18 patients (41.9% were Child-Pugh Class A, 12 (27.9% patients were Child-Pugh Class B and 13 (30.2% patients were Child-Pugh Class C. It was found that patients with severely high alpha-feto protein levels (>200 ng/ml, have 4 fold risk of multiple liver masses (OR: 4.05, 95% CI: 1.22-13.42. For the characterization of a liver mass as hepatocellular carcinoma, the diagnostic effectiveness of computerized tomography was 54.3%, and that of magnetic resonance imaging was 55.8%. Conclusion: As a result the patients with hepatocellular carcinoma can be diagnosed with combination of laboratory findings and imaging techniques. Alpha-feto protein levels are important for follow up of such patients and identifying the multiple mass presences.

  6. Analysis of periinterventional complications of intracranial angioplasty and stenting: A single center experience

    Highlights: • Periinterventional complications in 7.5% of patients with intracranial artery stenting. • 2.5% of periinterventional complications were perforator strokes. • 3.8% of patients developed a hemorrhagic stroke due to reperfusion injury. • Complications could be reduced by individualized measures to prevent perforator stroke or reperfusion injury. - Abstract: Background and purpose: Treatment of symptomatic intracranial atherosclerotic disease by angioplasty and stenting (PTAS) is limited by a high rate of periinterventional strokes. We performed a detailed analysis of these strokes at our center in order to identify strategies to reduce the risk of periinterventional complications. Methods: Case records and imaging data of 80 patients with a symptomatic 70–99% stenosis of a major intracranial artery treated with PTAS between July 2007 and December 2013 were reviewed. All patients had a sufficient response to aspirin and clopidogrel. Periinterventional strokes were categorized as either ischemic (perforator territory, distal embolic or delayed stent thrombosis) or hemorrhagic (intraparenchymal, subarachnoid). Results: Periinterventional complications occurred in 6/80 (7.5%) patients, consisting of 2 ischemic strokes (2.5%, both perforator territory), 3 hemorrhagic strokes (3.8%, 2 intraparenchymal due to reperfusion injury, 1 subarachnoid due to vessel rupture) and one death (1.3%) unrelated to stroke. All strokes occurred within 24 h after PTAS. Conclusion: Our retrospective data analysis suggests that the risk of periinterventional stroke after PTAS of symptomatic intracranial atherosclerotic disease might be reduced by sufficient antiplatelet therapy and optimized management of patients with high risk for reperfusion injury or perforator strokes, including selection of a stenting device adapted to individual vessel morphology

    Blood blister-like aneurysms (BBAs) are a controversial entity. They arise from non-branching sites on the supraclinoid internal carotid artery (ICA) and are suspected to originate from a dissection. Our aim is to describe the BBA cases seen in our center and to present a systematic review of the literature on BBAs. We analyzed the eleven cases of BBA admitted to our center from 2003 to 2012. We assessed the medical history, treatment modality (endovascular and/or surgery), complications and clinical outcome. The cohort included 8 women and 4 men with a mean age of 53.16 years. Treatment of the BBA consisted of stenting and coiling in 5 patients, stenting only in 4 patients, coiling and clipping in 1 patient, clipping only in 1 patient, and conservative treatment in 1 patient. A good outcome was found in 10 patients, as defined by a modified Rankin Scale (mRS) less than or equal to two at three months. A systematic review of the literature was performed, and 314 reported patients were found: 221 patients were treated with a primarily surgical approach, and 87 patients were treated with a primarily endovascular approach. A rescue or second treatment was required in 46 patients (21%). The overall estimated treatment morbidity rate was 17%, and the mortality rate was 15%. BBAs exhibit more aggressive behavior compared to saccular aneurysms, and more intra-operative complications occur with BBAs, independent of the treatment type offered. They are also significantly more likely to relapse and rebleed after treatment. Endovascular treatment offers a lower morbidity–mortality compared with surgical approaches. Multilayer flow-diverting stents appear to be a promising strategy.

    Infertility is common in women with end-stage liver disease. Successful liver transplant (LT), however, can restore childbearing potential. Controversy exists regarding the most appropriate immunosuppressive regimen and timing of conception following LT. We report the outcomes of a review of all pregnancies occurring following LT at King's College Hospital, London, from 1988 to 2004. Seventy-one pregnancies were recorded in 45 women. Tacrolimus (60%) and cyclosporin A (38%) were the predominant primary immunosuppressive agents used. Median age at conception was 29 years (range, 19-42), with a median time from LT to conception of 40 months (range, 1-111). There were 50 live births, and no maternal or fetal deaths related to pregnancy. There were no graft losses. Median gestation was 37 weeks (range, 24-42) with a median birth weight of 2,690 g (range, 554-4,260). Caesarean section was performed in 40% of pregnancies. Complications included pregnancy-induced hypertension in 20%, preeclampsia in 13%, acute cellular rejection in 17%, and renal impairment in 11%. There was no statistically significant difference in complication rates observed between immunosuppressive groups. Pregnancies occurring within 1-year posttransplant had an increased incidence of prematurity, low birth weight, and acute cellular rejection compared to those occurring later than 1 year. In conclusion, this study confirms that favorable outcomes of pregnancy post-LT can be expected for the majority of patients. However, delaying pregnancy until after 1-year post-LT is advisable, since doing so maybe associated with a lower risk of prematurity. PMID:16799943

    Background/Aim. Management of patients with recurrent glioblastoma (GB) comprises a therapeutic challenge in neurooncology owing to the aggressive nature of the disease with poor local control despite a combined modality treatment. The majority of cases recur within the highdose radiotherapy field limiting the use of conventional techniques for re-irradiation due to potential toxicity. Stereotactic radiosurgery (SRS) offers a viable noninvasive therapeutic option in palliative treatment...

    Rakhi Balachandran

    2013-01-01

    Methods : Retrospective review of medical records of seven neonates who underwent Norwood procedure at our institute from October 2010 to August 2012. Results: The median age at surgery was 9 days (range 5-16 days. All cases were done under deep hypothermic cardiopulmonary bypass and selective antegrade cerebral perfusion. The median cardiopulmonary bypass (CPB time was 240 min (range 193-439 min and aortic cross-clamp time was 130 min (range 99-159 min. A modified Blalock-Taussig (BT shunt was used to provide pulmonary blood flow in all cases. There were two deaths, one in the early postoperative period. The median duration of mechanical ventilation was 117 h (range 71-243 h and the median intensive care unit (ICU stay was 12 days (range 5-16 days. Median hospital stay was 30.5 days (range 10-36 days. Blood stream sepsis was reported in four patients. Two patients had preoperative sepsis. One patient required laparotomy for intestinal obstruction. Conclusions:Stage one Norwood is feasible in a limited-resource environment if supported by a dedicated postoperative intensive care and protocolized nursing management. Preoperative optimization and prevention of infections are major challenges in addition to preventing early circulatory collapse.

    This study aimed to investigate the effectiveness and reliability of micro-percutaneous nephrolithotomy (micro-PNL) for the management of kidney stones in pediatric patients. This retrospective study included 24 infants that underwent micro-PNL for renal stones between March 2012 and April 2015. The inclusion criteria included: age younger than 2 years, stone size renal access was achieved using USG in 11 patients and KUB fluoroscopy in 13 patients. The operation time and fluoroscopic screening time were 53.7 ± 10.35 and 1.4 ± 0.9 min, respectively. The mean hospital stay was 2.5 ± 0.8 days, and the mean drop in the hemoglobin level was 0.51 ± 0.34 g/dL. Bleeding requiring blood transfusion was not observed. A ureteral J stent was implanted perioperatively in four patients because of stone burden. Four patients complained of postoperative renal colic (Clavien grade 1) and postoperative fever was observed in two patients. Definitive success rates were as follows: the stone-free rate was 83.3% (n = 20) and residual fragments were observed in four patients. PMID:26209010

  14. Congenital cystic lesions of the lungs: The perils of misdiagnosis - A single-center experience

    2015-01-01

    Full Text Available Background: A majority of cystic lesions in the western world are detected antenatally, whereas, the diagnosis in our setup occurs once the child becomes symptomatic. Surgical management is primarily dictated by the presence of symptoms, recurrent infection, and rarely by the potential risk of malignant transformation. Materials and Methods: A retrospective analysis was carried out on all consecutive patients with cystic lung lesions managed at our center from January 2000 through June 2011 for antenatal diagnosis, presentation, diagnostic modalities, treatment, and complications. Results: Forty cystic lung lesions were identified. Only 8% were antenatally detected. Out of 40, the final diagnosis was congenital cystic adenomatoid malformation in 19, congenital lobar emphysema in 11, and bronchogenic cysts and pulmonary sequestration in five each. Of these, 20% had received a course of prior antitubercular therapy and 30% had an intercostal drain inserted prior to referral to our center. Postoperative morbidity in the form of bronchopleural fistula, pneumothorax, and non-expansion of the residual lung was noted in 10% of the patients. Conclusion: Antenatal diagnosis of these lesions is still uncommon in third world countries. Prior to referral to a pediatric surgical center a large number of patients received antitubercular drugs and an intercostal drain insertion, due to incorrect diagnosis.

    Children treated for cancer face the risk of complications later in life, including pulmonary dysfunction. The objective of this study was to evaluate frequency and severity of pulmonary complications in survivors of childhood leukemia and lymphoma treated with chemotherapy alone or combined with radiotherapy. Seventy cancer survivors of hematological malignancies were evaluated for pulmonary complications through history taking, chest examination, high-resolution computed tomography (HRCT) chest, and pulmonary function testing (PFTs). Although most survivors were not clinically compromised, the spectrum of impaired PFTs included obstructive pattern (14.3%), restrictive pattern (5.7%), and mixed pattern (20%). Significant pulmonary dysfunction was seen in children older than 10 years of age (P = .003), and in patients treated with combined chemotherapy and radiotherapy (72.7%) compared with those treated with chemotherapy alone (25%) (P = .001). Cumulative dose of bleomycin was significantly associated with abnormal PFTs (P = .04). Multivariate analysis revealed methotrexate therapy as significant predictor of abnormal PFTs (P = .002). Male patients who received combined therapy showed higher frequency of restrictive, obstructive lung disease, abnormal respiratory reactance, and peripheral airway disease (P = .007, P = .04, P = .002, P = .003, P = .05, respectively). Those with abnormal CT findings (n = 14) had lower forced vital capacity (FVC%), forced expiratory volume in 1 second (FEV(1)%), and peak expiratory flow (PEF%) when compared to cases with normal CT (P = .001, P < 0.001, P = .001, respectively). Subclinical pulmonary function abnormalities are found in survivors of childhood hematological malignancies previously treated and off therapy. Pulmonary dysfunction is more evident with combined chemotherapy and radiotherapy, bleomycin, and methotrexate are the most incriminated chemotherapeutic agents, and males are at higher risk than females; therefore a specific and extended follow-up is warranted.

    2014-01-01

    Surgery in high grade gliomas (HGG) is often related to peri-operative complications, that may require neurocritical intensive care unit (NICU) admittance. Actually there is no consensus whether there is real need for NICU for this patients; often the possibility is related to surgeon preferences. In literature there are still little data on clinical parameters associated with long-term outcome after neurocritical care. We retrospectively analyzed 175 patients, that underwent surgical resecti...

    2015-12-01

    DISCUSSION: Tenofovir seems to exert a better viral replication inhibition (though not statistically significant and to show transaminases improvement in comparison with entecavir, which, in turn, results more effective in HBeAg/HBsAg seroconversion. Both drugs have a high safety profile in terms of side effects. [Article in Italian

  18. Conversion from temporary to tunneled catheters by nephrologists: report of a single-center experience

    Silva, Bruno C; Rodrigues, Camila E; Abdulkader, Regina CRM; Elias, Rosilene M

    2016-01-01

    Background Nephrologists have increasingly participated in the conversion from temporary catheters (TC) to tunneled-cuffed catheters (TCCs) for hemodialysis. Objective To prospectively analyze the outcomes associated with TCC placement by nephrologists with expertise in such procedure, in different time periods at the same center. The impact of vancomycin or cefazolin as prophylactic antibiotics on the infection outcomes was also tested. Patients and methods Hemodialysis patients who presented to such procedure were divided into two cohorts: A (from 2004 to 2008) and B (from 2013 to 2015). Time from TC to TCC conversion, prophylactic antibiotics, and reasons for TCC removal were evaluated. Results One hundred and thirty patients were included in cohort A and 228 in cohort B. Sex, age, and follow-up time were similar between cohorts. Median time from TC to TCC conversion was longer in cohort A than in cohort B (14 [3; 30] vs 4 [1; 8] days, respectively; P⩽0.0001). Infection leading to catheter removal occurred in 26.4% vs 18.9% of procedures in cohorts A and B, respectively, and infection rate was 0.93 vs 0.73 infections per 1,000 catheter-days, respectively (P=0.092). Infection within 30 days from the procedure occurred in 1.4% of overall cohort. No differences were observed when comparing vancomycin and cefazolin as prophylactic antibiotics on 90-day infection-free TCC survival in a Kaplan–Meier model (log-rank = 0.188). TCC removal for low blood flow occurred in 8.9% of procedures. Conclusion Conversion of TC to TCC by nephrologists had overall infection, catheter patency, and complications similar to data reported in the literature. Vancomycin was not superior to cefazolin as a prophylactic antibiotic. PMID:27114715

    2011-11-15

    To evaluate the effect of temporary stent graft placement in the treatment of benign anastomotic biliary strictures. Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patients had strictures following a liver transplantation; three of them in bilio-enteric anastomoses and one in a choledocho-choledochostomy. Four of the other five patients had strictures at bilio-enteric anastomoses, which developed after complications following laparoscopic cholecystectomies and in one after a Whipple procedure for duodenal carcinoma. In eight patients, balloon-expandable stent-grafts were placed and one patient was treated by insertion of a self-expanding stent-graft. In the transplant group, treatment of patients with bilio-enteric anastomoses was unsuccessful (mean stent duration, 30 days). The patient treated for stenosis in the choledocho-choledochostomy responded well to consecutive self-expanding stent-graft placement (total placement duration, 112 days). All patients with bilio-enteric anastomoses in the non-transplant group were treated successfully with stent-grafts (mean placement duration, 37 days). Treatment of benign biliary strictures with temporary placement of stent-grafts has a positive effect, but is less successful in patients with strictures developed following a liver transplant.

    Background and objectives: Transplant “tourism” typically refers to the practice of traveling outside the country of residence to obtain organ transplantation. This study describes the characteristics and outcomes of 33 kidney transplant recipients who traveled abroad for transplant and returned to University of California, Los Angeles (UCLA) for follow-up.

  2. Compliance and toxicity of adjuvant CMF in elderly breast cancer patients: a single-center experience

    Few data are available on compliance and safety of adjuvant chemotherapy when indicated in elderly breast cancer patients; CMF (cyclophosphamide, methotrexate, fluorouracil) can be reasonably considered the most widely accepted standard of treatment. We retrospectively reviewed compliance and safety of adjuvant CMF in patients older than 60. The treatment was indicated if patients had no severe comorbidity, a high-risk of recurrence, and were younger than 75. Toxicity was coded by NCI-CTC. Toxicity and compliance were compared between two age subgroups (<65, ≥ 65) by Fisher exact test and exact Wilcoxon rank-sum test. From March 1991 to March 2002, 180 patients were identified, 100 older than 60 and younger than 65, and 80 aged 65 or older. Febrile neutropenia was more frequent among older patients (p = 0.05). Leukopenia, neutropenia, nausea, cardiac toxicity and thrombophlebitis tended to be more frequent or severe among elderlies, while mucositis tended to be more evident among younger patients, all not significantly. Almost one half (47%) of the older patients receiving concomitant radiotherapy experienced grade 3–4 haematological toxicity. Compliance was similar in the two groups, with 6 cycles administered in 86% and 79%, day-8 chemotherapy omitted at least once in 36% and 39%, dose reduction in 27% and 38%, prolonged treatment duration (≥ 29 weeks) in 10% and 11% and need of G-CSF in 9% and 18%, among younger and older patients, respectively. Our data show that, in a highly selected population of patients 65 or more years old, CMF is as feasible as in patients older than 60 and younger than 65, but with a relevant burden of toxicity. We suggest that prospective trials in elderly patients testing less toxic treatment schemes are mandatory before indicating adjuvant chemotherapy to all elderly patients with significant risk of breast cancer recurrence

  3. BIOIMPEDANCE ANALYSIS IN HAEMODIALYSIS PRACTICE: SHORT REVIEW AND SINGLE CENTER EXPERIENCE

    2012-03-01

    Full Text Available Bioimpedance analysis has been widely used to estimate a hydration state, lean and fat mass in haemodialysis patients. The aim of our study was to investigate the validity and usefulness of bioimpedance analysis in routine dialysis practice. Last two years we used the body composition monitoring (BCM, Fresenius Medical Care, method based on whole body multifrequency bioimpedance spectroscopy (BIS, compared with traditional clinical data. For BIS data verification, hydration status of 32 stable HD patients with dialysis vintage more than 3 years and clinically well established dry weight were studied. Only in three cases BIS data seems underestimated in serial measurements. Next step, 28 healthy subjects and 116 dialysis patients were studied. Total body water and extracellular volume (ECV were significantly higher in dialysis group (P<0.01, and there was not any difference in intracellular volume (ICV. Mean AP was similar in patients with moderate (<15% and massive (>15% relative overhydration (RO = overhydration / ECV, at the same time, average number of antihypertensive medications was significantly higher in more overhydrated patients (3.1 vs 1.2. In clinical practice RO is more convenient indicator as compared to standard overhydration volume /dry weight ratio. Mutual application of the BIS and blood volume monitoring allows more rapid and safe dry weight achievement. BIS was useful tool for hydration status monitoring in routine haemodialysis practice, and further work need to be done to clarify BIS validity for nutritional status estimation.

    Full Text Available Objective: We reviewed the clinical details and treatment outcome of children with newly diagnosed acute lymphoblastic leukemia (ALL to determine the significance of already established prognostic factors in our patients. Setting: A tertiary care hospital in Karachi, Pakistan. Study Design: This is a retrospective study. Materials and Methods: Children diagnosed with ALL were evaluated over a period of 17 years (January 1, 1989 to December 31, 2006. Data was collected by reviewing the medical records of the patients and the prognostic factors analyzed by us include age, gender, white blood cell count, central nervous system and mediastinal involvement at presentation, morphology and immunophenotype of the blast cells, and response to induction therapy. Results: There were 46 patients diagnosed during the study period and on regular follow-up. Forty five (97.8% of these were in complete remission after 28 days of induction therapy. Thirty patients (65.2% were alive and doing well at the time of study. Of these 30 patients, 26 (86.6% remained relapse free while only four (13.3% had relapsed. The remaining 16 patients (34.7% did not survive including 11 (68.7% who had a relapse. Only significant variables in terms of prognosis were age and ALL phenotype with a P value 0.04 and 0.03 respectively. Conclusion: We found that ALL is a frequent childhood hematological malignancy in our setting and is more prevalent in males and children less than ten years of age. Age and leukemia phenotype emerged as the important prognostic factors in pediatric ALL in our patients.

    Full Text Available Background: There is a paucity of data on the outcome following the treatment for acute lymphoblastic leukemia (ALL from developing countries. Materials and Methods: Two hundred and thirty-eight consecutive patients with ALL <30 years of age diagnosed between January 2005 and December 2011 were analyzed retrospectively. Patients were treated modified Berlin, Frankfurt, and Munster 95 protocol. Event-free survival (EFS was calculated using Kaplan-Meier survival analysis and variables were compared using log-rank test. Results: The EFS was 63.4% at a median follow-up was 32.7 months. On univariate analysis National Cancer Institute (NCI risk stratification, sex, white blood cell count, day 8 blast clearance, and income were significantly associated with EFS. However, on multivariate analysis only female sex (P = 0.01 and day 8 blast clearance (P = 0.006 were significantly associated with EFS. Seventy-four of 238 (31% patients had recurrent leukemia. The common sites of relapse were bone marrow in 55/74 (75% patients and central nervous system in 11/74 (20% patients. Conclusion: Compared to western data, there was an increased proportion of NCI high-risk patients and T-cell immunophenotype in our study. There has been an improvement in outcome of patients with ALL at our center over the last 2 decades. Female sex and clearance of blast in peripheral blood by day 8 of induction was associated with better EFS.

    2016-08-01

    A dramatic increase in twin pregnancies has been observed in the past few decades, primarily related to assisted reproductive techniques (ART) and increased average maternal age during pregnancy. Multiple pregnancies, compared to singleton pregnancies, are associated with greater perinatal morbidity and mortality. The present study evaluated the perinatal outcomes of pregnancies with discordant anomalous twins in a tertiary maternity ward in a developing country. Data were retrospectively collected from the Instituto Fernandes Figueira/FIOCRUZ, Brazil between January 2002 and December 2014. We identified 74 twin pregnancies with discordant anomalous twins. Final data analysis was based on 40 pregnancies. Congenital defects were classified according to the International Classification of Diseases: ICD-10: the digestive system was responsible in 27 (34%) cases; the central nervous system was responsible in 18 (22%) cases; the urinary tract was responsible in 14 (17%) cases; and the circulatory system was responsible in 14 (17%) cases. A total of 19 deaths occurred during the study period, and delivery before 30.4 weeks was a significant prediction of fetal death (p = .01). The presence of hydrops in the affected fetus was related to a higher number of deaths in healthy fetuses and contributed to a worse prognosis. The presence of this condition was the cause of 12 (55.6%) deaths in healthy fetuses. A 10 times higher risk of death of a normal co-twin was observed in cases of death of the anomalous twin (p = .002, OR 10.55, 95% CI: 1.9-58.52). PMID:27321141

    Full Text Available Prospective studies concerning liver disease in pediatric cystic fibrosis patients are scarce. The present study aimed to describe the prevalence and clinical expression of cystic fibrosis - related liver disease, in a cohort of 62 pediatric patients. Descriptive study, resulting from the prospective evaluation, between 1994 and 2009, of 62 pediatric patients (age <18 years with cystic fibrosis. The follow-up protocol included a clinical assessment every 2 months, liver function tests every 6 months and annual liver ultrasonography. The cumulative prevalence of liver disease was 11.2% (7/62 cases. All patients had ΔF508 mutation and pancreatic insufficiency, none had meconium ileus. The liver involvement became clinically evident at a mean age of 8 years (3-15 years, revealed by hepatomegaly or hepatosplenomegaly (3 cases and/ or abnormalities of liver function tests (3 cases changes of liver ultrasound (7 cases with evidence of portal hypertension (2 cases. Four patients were submitted to liver biopsy; biliary fibrosis was documented in one case, focal biliary cirrhosis in 2 cases and multilobular cirrhosis in another case. Within a median 11.6 years follow-up period (all patients under UDCA therapy after liver disease diagnosis, progression of liver disease was observed in 2 patients; one patient developed refractory variceal bleeding and progressive hepatic failure, requiring liver transplant. The results of the present study agree with those of previous pediatric studies, further documenting clinical expression of liver disease in CF patients, which is usually detected in the first decade of life and emphasize the contribution of ultrasound to early diagnosis of liver involvement. Moreover, although advanced liver disease is a relatively rare event, early isolated liver transplantation may have to be considered at this age group.

  9. Mortality of IgA nephropathy patients: a single center experience over 30 years.

    Hajeong Lee

    Full Text Available Research on the prognosis of IgA nephropathy (IgAN has focused on renal survival, with little information being available on patient survival. Hence, this investigation aimed to explore long-term patient outcome in IgAN patients. Clinical and pathological characteristics at the time of renal biopsy were reviewed in 1,364 IgAN patients from 1979 to 2008. The outcomes were patient death and end stage renal disease (ESRD progression. Overall, 71 deaths (5.3% and 277 cases of ESRD (20.6% occurred during 13,916 person-years. Ten-, 20-, and 30-year patient survival rates were 96.3%, 91.8%, and 82.7%, respectively. More than 50% patient deaths occurred without ESRD progression. Overall mortality was elevated by 43% from an age/sex-matched general population (GP (standardized mortality ratio [SMR], 1.43; 95% confidence interval [CI], 1.04-1.92. Men had comparable mortality to GP (SMR, 1.22; 95% CI, 0.82-1.75, but, in women, the mortality rate was double (SMR, 2.17; 95% CI, 1.21-3.57. Patients with renal risk factors such as initial renal dysfunction (estimated glomerular filgration rate <60 ml/min per 1.73 m(2; SMR, 1.70; 95% CI, 1.13-2.46, systolic blood pressure ≥ 140 mmHg (SMR, 1.88; 95% CI, 1.19-2.82 or proteinuria ≥ 1 g/day (SMR, 1.66; 95% CI, 1.16-2.29 had an elevated mortality rate. Patients with preserved renal function, normotension, and proteinuria <1 g/day, however, had a similar mortality rate to GP. When risk stratification was performed by counting the number of major risk factors present at diagnosis, low-risk IgAN patients had a mortality rate equal to that of GP, whereas high-risk patients had a mortality rate higher than that of GP. This investigation demonstrated that overall mortality in IgAN patients was higher than that of GP. Women and patients with renal risk factors had a higher mortality than that of GP, Therefore, strategies optimized to alleviate major renal risk factors are warranted to reduce patient mortality.

  10. IgA Nephropathy: A Twenty Year Retrospective Single Center Experience

    Jacob Rube

    2009-01-01

    Full Text Available IgA nephropathy (IgAN is a common glomerular disease whose etiology is unknown. Previous studies have described the clinical and laboratory features but none have specifically compared patients during different time periods. This 20 year retrospective study was performed to assess trends in the severity of IgAN from 1989–2008. We reviewed 57 patient charts that contained a confirmed biopsy diagnosis of IgAN and recorded data at the time of diagnosis and the final follow-up appointment. Clinical data included physical examination, urine, and blood tests. Patients were separated into two cohorts, Cohort 1 1989–1998 and Cohort 2 1999–2008. An increase in severity was noted in Cohort 2 based on a significantly higher Up/c and lower serum albumin level. Other prognostic indicators including GFRe, hematocrit, and glomerular injury score also demonstrated a trend towards more severe disease over the past 20 years. The patients in both Cohorts received similar treatments and had comparable renal function at the last follow-up visit. Based on our findings, we suggest that although a kidney biopsy is required to diagnose IgAN, the procedure may not be necessary in patients clinically suspected of having the disease but who have normal kidney function and minimal urine abnormalities.

  11. Endovascular Repair of Traumatic Rupture of the Thoracic Aorta: Single-Center Experience

    Purpose. Traumatic rupture of the thoracic aorta secondary to blunt chest trauma is a life-threatening emergency and a common cause of death, usually following violent collisions. The objective of this retrospective report was to evaluate the efficacy of endovascular treatment of thoracic aortic disruptions with a single commercially available stent-graft. Methods. Nine men (mean age 29.5 years) were admitted to our institution between January 2003 and January 2006 due to blunt aortic trauma following violent motor vehicle collisions. Plain chest radiography, spiral computed tomography, aortography, and transesophageal echocardiography were used for diagnostic purposes in all cases. All patients were diagnosed with contained extramural thoracic aortic hematomas, secondary to aortic disruption. One patient was also diagnosed with a traumatic thoracic aortic dissection, secondary to blunt trauma. All subjects were poor surgical candidates, due to major injuries such as multiple bone fractures, abdominal hematomas, and pulmonary contusions. All repairs were performed using the EndoFit (LeMaitre Vascular) stent-graft. Results. Complete exclusion of the traumatic aortic disruption and pseudoaneurysm was achieved and verified at intraoperative arteriography and on CT scans, within 10 days of the repair in all patients. In 1 case the deployment of a second cuff was necessary due to a secondary endoleak. In 2 cases the left subclavian artery was occluded to achieve adequate graft fixation. No procedure-related deaths have occurred and no cardiac or peripheral vascular complications were observed within the 12 months (range 8-16 months) follow-up. Conclusions. This is the first time the EndoFit graft has been utilized in the treatment of thoracic aortic disruptions secondary to chest trauma. The repair of such pathologies is technically feasible and early follow-up results are promising

    Full Text Available Objective: To determine the epidemiological, clinical, laboratory characteristics as well as outcome of 411 patients with bowel obstruction in Southern Iran. Methods: This was a cross-sectional study being performed in Shahid Faghihi hospital of Shiraz between 2006 and 2012. We reviewed the medical charts of the 411 patients with initial diagnosis of bowel obstruction who were admitted to our center during the study period. The patients’ demographic, clinical and laboratory findings as well as their management and outcome was recorded in data gathering forms. The data were then analyzed according to the outcome and clinical characteristics. Results: Among the 411 patients with initial diagnosis of bowel obstruction, 253 (61.5% were men and 158 (38.5% were women. The mean age of the patients was 48.2±19.7 years. Besides, 73.6% were observed and 26.4% were operated. Those who were operated had those who underwent operation had significantly lower frequency of obstipation (28.1% vs. 71.9%; p=0.045 and abdominal distention (32.3% vs. 67.7%; p=0.007. Intraoperative findings included adhesion band formation in 50 (48.1%, mass 18 (17.3%, and hernia 7 (6.7%. We found that the frequency of malignancy was significantly higher in those who were managed conservatively compared to those undergoing operation (64.3% vs. 35.7%; p=0.042. The mean hospital stay was significantly higher in those who underwent operation (8.1±7.5 vs. 2.6±2.2 days; p=0.035. Conclusion: The results of this study demonstrates although some signs and symptoms, such as abdominal pain, vomiting, abdominal tenderness, abdominal distention, and obstipation, were more common among the patients with bowel obstruction, they were not sensitive and specific enough for definite diagnosis. Due to the lack of positive predictive value of clinical signs and symptoms in diagnosis of bowel obstruction, a reasonable and logical modality is needed for bowel obstruction diagnosis with better accuracy.

    2016-01-01

    Combined immunodeficiencies (CIDs) include a group of inherited monogenic disorders. CIDs are characterized by defective cellular and humoral immunities that lead to severe infections. CIDs can be classified according to immunologic phenotypes as T(-)B(-)NK(-) CID, T(-)B(-)NK(+) CID, T(-)B(+)NK(-) CID and T(-)B(+)NK(+) CID. In a 20-year period, from 1994 to 2014, a total of 40 CID patients were diagnosed at the Pediatric Immunology of Erciyes University Medical Faculty in Kayseri, Turkey. The gender ratio (F/M) was 3/5. The median age at the onset of symptoms was 2 months (range, 15 days - 15 years). Of the 14 T(-)B(-)NK(-) CIDs, 6, 2 (siblings), 1, 1 and 4 had a mutation in the ADA, PNP, Artemis, RAG1 genes and unknown genetic diagnosis respectively. Of the 15 T(-)B(-)NK(+) CIDs, 3, 2 (siblings) and 10 had a mutation in the RAG1, XLF/Cernunnos genes and unknown genetic diagnosis respectively. Of the 9 T(-)B(+)NK(-) CIDs, 2 siblings, 1, 1 and 5 had a mutation in the ZAP70, IL2RG, DOCK8 genes and unknown genetic diagnosis respectively. Of the 2 T(-)B(+)NK(+) CIDs, 2 had a mutation in the MAGT1 and ZAP70 genes respectively. Of the 40 CIDs, 26 (65%) were died and 14 (35%) are alive. Eight patients received HSCT (hematopoietic stem cell transplantation) with 62.5% survival rate. As a result, patients presented with severe infections in the first months of life have to be examined for CIDs. Shortening time of diagnosis would increase chance of HSCT as life-saving treatment in the CID patients. PMID:27095930

    2015-11-01

    Full Text Available Aim: Families of children with acute urticaria often think that there is food allergy in children with urticaria and insist for skin tests. In this study, it was aimed to determine whether skin prick tests are necessary in cases presented with acute urticaria, in whom other causes of acute urticaria are excluded. Material and Method: A test panel involving cow milk, egg white, wheat, hazelnut, peanut, soybean, walnut, sesame, and tuna fish antigens was applied to the children presented with acute urticaria between 1 August 2013 and 1 August 2014, in whom other causes of acute urticaria were excluded and suspected food allergy was reported by parents. Results: Overall, 574 children aged 1-14 years were included to the study. Of the patients, sensitization against at least one food antigen was detected in 22.3% (128/574 of the patients. This rate was found to be 31.9% among those younger than 3 years, while 19.3% in those older than 3 years. Overall, sensitization rates against food allergen in panel were as follows: egg white, 7.3%; wheat, 3.3%; cow milk, 2.7%,; sesame, 2.8%; hazelnut, 2.4%; soybean, 2.3%; peanut, 1.9%, walnut, 1.6%; tuna fish, 1.6%. In general, the history of patients wasn%u2019t compatible with food sensitization detected. Discussion: Sensitization to food allergens is infrequent in children presented with acute urticaria, particularly among those older than 3 years despite expressions of parent and skin prick tests seems to be unnecessary unless strongly suggestive history is present.

    Songfeng Yu

    Full Text Available BACKGROUND: De novo cancers are a growing problem that has become one of the leading causes of late mortality after liver transplantation. The incidences and risk factors varied among literatures and fewer concerned the Eastern population. AIMS: The aim of this study was to examine the incidence and clinical features of de novo cancers after liver transplantation in a single Chinese center. METHODS: 569 patients who received liver transplantation and survived for more than 3 months in a single Chinese center were retrospectively reviewed. RESULTS: A total of 18 de novo cancers were diagnosed in 17 recipients (13 male and 4 female after a mean of 41 ± 26 months, with an overall incidence of 3.2%, which was lower than that in Western people. Of these, 8 (3.32% cases were from 241 recipients with malignant liver diseases before transplant, while 10 (3.05% cases were from 328 recipients with benign diseases. The incidence rates were comparable, p = 0.86. Furthermore, 2 cases developed in 1 year, 5 cases in 3 years and 11 cases over 3 years. The most frequent cancers developed after liver transplantation were similar to those in the general Chinese population but had much higher incidence rates. CONCLUSIONS: Liver transplant recipients were at increased risk for developing de novo cancers. The incidence rates and pattern of de novo cancers in Chinese population are different from Western people due to racial and social factors. Pre-transplant malignant condition had no relationship to de novo cancer. Exact risk factors need further studies.

    2008-01-01

    Full Text Available Proper management of living kidney donors is a very important aspect of all renal transplants. To date, approximately 60,000 living donor nephrectomies have been performed worldwide and about 20 deaths directly related to the operation have been reported. The most common cause of death has been pulmonary embolism. Wound infection following surgery is the third most common nosocomial infection, and is dependent on the surgeon and his/her team, the operating room, number and virulence of contaminated bacteria, patient characteristics (immunity and defense, as well as time and duration of administration of antibiotics. Approach to the prophylaxis of wound infection in kidney donors varies in different transplant centers. This study was conducted at the Emam Hospital, Tabriz, Iran in order to delineate the protocol regarding antibiotic usage after donor nephrectomy. One hundred kidney donors were enrolled in the study. They were classified randomly in two groups: Group-1, comprising 50 donors, who received antibiotics immediately following surgery and for at least seven days thereafter. Group-2, comprised of 50 donors, in whom one gram of cephazoline was injected intravenously before anesthesia and continued for 24 hours after surgery. The patients were followed-up for one month with particular emphasis on occurrence of wound infection. One patient in Group-1, and two in Group-2 had wound infection; the difference was not statistically significant (p = > 0.5. Our study suggests that antibiotic prophylaxis started before incision and continued for 24 hours after donor nephrectomy is safe and effective in preventing wound infection.

    Full Text Available Background: Pulmonary valve regurgitation following balloon valvuloplasty for moderate to severe pulmonary valve stenosis is a known late outcome of this procedure. Objective: The aim of the study was to characterise the status of pulmonary regurgitation on follow up after pulmonary valve balloon dilatation (PVBD, and to study the determinant of the severity of PR. Materials and Methods: We retrospectively reviewed 50 consecutive patients, aged 2 days to 18 years, with isolated pulmonary valve stenosis, who had undergone PVBD in 2004-2009 and were assessed with follow-up Doppler echocardiography. The impact of balloon to annulus ratio, age, and valve anatomy on the late development of moderate and severe pulmonary valve regurgitation following balloon valvuloplasty was analysed. Results: Six patients (12% had no pulmonary valve regurgitation; 32 (64% had mild, 9 (18% had moderate, and 3 (6% had severe pulmonary valve regurgitation at a mean follow-up of 4 years. Balloon to annulus ratio, age, and valve anatomy were not statistically significant predictors for moderate and severe pulmonary valve regurgitation. Conclusions: The majority of patients in our population had mild pulmonary valve regurgitation. Moderate to severe pulmonary valve regurgitation was well tolerated at midterm follow-up. Age, balloon to annulus ratio, and valve anatomy were not statistically significant predictors for the late development of moderate and severe valve regurgitation. Large and longer follow-up studies are needed to address this question.

    Nephronophthisis (NPHP) is a recessive disorder of the kidney that is the leading genetic cause of end-stage renal failure in children. Egypt is a country with a high rate of consanguineous marriages; yet, only a few studies have investigated the clinical and molecular characteristics of NPHP and related ciliopathies in the Egyptian population. We studied 20 children, from 17 independent families, fulfilling the clinical and the ultrasonographic criteria of NPHP. Analysis for a homozygous deletion of the NPHP1 gene was performed by polymerase chain reaction on the genomic DNA of all patients. Patients were best categorized as 75% juvenile NPHP, 5% infantile NPHP, and 20% Joubert syndrome-related disorders (JSRD). The mean age at diagnosis was 87.5 + 45.4 months, which was significantly late as compared with the age at onset of symptoms, 43.8 ± 29.7 months (P Egyptian children. Also, we report that homozygous NPHP1 deletions account for 29.4% of NPHP in the studied families in this cohort, thereby confirming the diagnosis of type-1 NPHP. Moreover, our findings confirm that NPHP1 deletions can indeed be responsible for JSRD. PMID:22982934

    BACKGROUND: Acute hepatic failure (AHF) is a devastating clinical syndrome with a high mortality rate. The outcome of AHF varies with etiology, but liver transplantation (LT) can significantly improve the prognosis and survival rate of such patients. This study aimed to detect the role of LT and artificial liver support systems (ALSS) for AHF patients and to analyze the etiology and outcome of patients with this disease. METHODS: A retrospective analysis was made of 48 consecutive patients with AHF who fulfilled the Kings College Criteria for LT at our center. We analyzed and compared the etiology, outcome, prognosis, and survival rates of patients between the transplantation (LT) group and the non-transplantation (N-LT) group. RESULTS: AHF was due to viral hepatitis in 25 patients (52.1%; hepatitis B virus in 22), drug or toxic reactions in 14 (29.2%; acetaminophen in 6), Wilson disease in 4 (8.3%), unknown reasons in 3 (6.3%), and miscellaneous conditions in 2 (4.2%). In the LT group, 36 patients (7 underwent living donor LT, and 29 cadaveric LT) had an average model for end-stage liver disease score (MELD) of 35.7. Twenty-eight patients survived with good graft function after a follow-up of 27.3± 4.5 months. During the waiting time, 6 patients were treated with ALSS and 2 of them died during hospitalization. The 30-day, 12-month, and 18-month survival rates were 77.8%, 72.2%, and 66.7%, respectively. In the N-LT group, 12 patients had an average MELD score of 34.5. Four patients were treated with ALSS and all died during hospitalization. The 90-day and 1-year survival rates were only 16.7% and 8.3%, respectively. CONCLUSIONS: Hepatitis is the most prominent cause of AHF at our center. Most patients with AHF, who fulfill the Kings College Criteria for LT, did not survive longer without LT. ALSS did not improve the prognosis of AHF patients, but may extend the waiting time for a donor. Currently, LT is still the most effective way to improve the prognosis of AHF patients.

    2013-01-01

    Full Text Available Introduction: Historically, metastatic renal cell carcinoma (RCC has had poor prognosis; the outcomes have improved with the introduction of tyrosine-kinase inhibitors, such as sunitinib. There is no reported literature from India on the use of sunitinib in metastatic RCC. We present an analysis of sunitinib at our institute over 4 years. Materials and Methods: An unselected population of patients with metastatic or relapsed metastatic RCC receiving sunitinib was analyzed with respect to patient characteristics, response, toxicity, and outcomes. Results: Fifty-nine patients (51 males, 8 females with a median age of 55 years were included in the study. Lungs and bones were the most common site of metastases. The patients received a median number of 4 cycles, with 23 patients requiring dose-modification and 12 discontinuing therapy due to toxicity. Overall, 38 patients (65% had CR, PR, or standard deviation while 14 had progression or death at initial evaluation. The median progression-free survival (PFS was 11.4 months and overall survival was 22.6 months. Hand-foot syndrome, fatigue, mucositis, skin rash, and vomiting were seen more often among our patients, whereas hypertension was not as common compared with previously published reports. Conclusion: Sunitinib is a viable option for the treatment of metastatic RCC and shows a comparable PFS in Indian patients. Although toxicity remains a concern, most of the adverse effects can be managed conservatively. Careful patient selection, tailoring the dose of therapy, adequate counseling, and careful follow-up is essential for optimum therapy.

    2011-01-01

    Background The Medtronic InSync Sentry is the first available cardiac resynchronization therapy defibrillator (CRT-D)which can monitor fluid status by measuring intrathoracic impedance. This study was designed to observe the effectiveness of intrathoracic impedance monitoring on detecting aggravation of heart failure.Methods We retrospectively analyzed the clinical data of 14 consecutive patients. Patients were regularly followed up every 3-6 months after the implantation. At each visit, interrogation of the device was done. Patients were instructed to inform the researcher on hearing the device alert, and to take extra 40 milligrams of furosemidum if they had aggravated symptoms later. If the symptoms could not be relieved, they were asked to see a doctor. Data about heart failure hospitalization were collected from the medical record.Results During 18-48 months follow-up, a total of 7 patients encountered 28 alert events. On one hand, alert events appeared before all deteriorated symptoms and heart failure hospitalizations. On the other hand, there were 23 alerts followed by deterioration of heart failure symptoms, and 2 alerts related to 2 hospitalizations caused by pulmonary infection in one patient. Only 5 patients were hospitalized 10 times for deterioration of cardiac function.Conclusion The function of intrathoracic impedance monitoring is reliable in predicting deterioration of heart failure.

  9. Vibrational angioplasty in recanalization of chronic femoropopliteal arterial occlusions: Single center experience

    Purpose: This prospective study aims to present the overall success rate, safety and long-term outcome of vibrational angioplasty technique, in the treatment of chronic total femoropopliteal occlusions in our institute. Methods: Between October 2000 and December 2008, patients with chronic total femoropoliteal arterial occlusions, treated with vibrational angioplasty during the same session after a failed attempt with conventional recanalization technique, were included. Patient's follow up included serial ankle-brachial index measurements and arterial duplex ultrasound examinations at 1, 3, 6, 12, 24, 36 and 48 months. Results: Twenty-seven patients (16 males and 11 females) and twenty-eight lesions were included in our study. Twenty-five lesions (89.3%) were successfully recanalized. Pain relief was noticed in twenty-one cases. From ten lesions with tissue loss (ulcer or gangrene) in successfully recanalized occlusions, six healed without major, or minor amputation. One non-healing amputation stump was healed after recanalization, without further complications. Four limbs underwent amputation (one minor and three major) despite successful recanalization, however all had an excellent healing of the amputation stump without further complications. The Kaplan–Meier test demonstrated 90%, 85% and 70% amputation-free survival rate at 12, 24 and 36 months, respectively. No major or minor complications were encountered. Conclusions: Vibrational angioplasty is a safe, effective and durable endovascular technique for the treatment of chronic total occlusions in patients with limb ischemia that would be difficult to recanalize using conventional intraluminal techniques

    2015-01-01

    The aim of the present study was to evaluate the incidence and clinical features of de novo tumors in patients undergoing liver transplantation in our center as well as to assess survival. We retrospectively analyzed 168 liver transplantations (159 patients) performed from May 2006 to May 2014. The incidence of de novo tumors was 7.5% (n = 12). The mean age at diagnosis was 63 ± 7 years. The most frequent neoplasms were non melanoma skin tumors and adenocarcinomas. Fifty percent of the tumors developed in the second and third year after transplantation. Type of immunosuppression did not influence tumoral type, although most patients receive tacrolimus in combination with mycofenolate and/or corticoids. The mean duration of follow-up after diagnosis of the tumor was 25 ± 29 months (range 0-76) and the mortality was 41%. The actuarial probability of survival at 1 and 5 years was 83 and 55%, respectively. De novo tumors are frequent after liver transplantation and their clinical course differs from that in the general population. Because their clinical course is more aggressive, regular follow up of these patients is essential for early diagnosis. PMID:25637895

    2015-01-01

    Conclusion: LS varies from being a highly aggressive disease of the penis and anterior urethra to a burnt out condition affecting just the meatus and surrounding glans. Early diagnosis and treatment are required to prevent its complication and associated morbidity. Management depends on the anatomical location of lesion, extent of involvement, rapidity of progression and its severity. Use of BMG in LS induced urethral stricture has shown encouraging results.

    Full Text Available Purpose: To determine the main causes of thyrotoxicosis and to compare the clinical and biochemical fetaures of the patients according to the underlying cause of thyrotoxicosis. Material and Method: Five hundred ninety-two patients, who were consecutively diagnosed with thyrotoxicosis, were retrospectively analysed. Symptoms of thyrotoxicosis, serum thyroid-stimulating hormone (TSH, free T3 and free T4 levels, anti-thyroglobulin autoantibody (TGAb, anti-thyroid peroxidase autoantibody (TPOAb and ultrasonographic features were recorded. To determine the cause of thyrotoxicosis, Tc-99m pertechnetate thyroid scintigraphy was performed in all patients except for pregnant women. The clinical and biochemical results were compared between the patients with different diagnosis of thyrotoxicosis. Results: 40.9% of patients were diagnosed with toxic multinodular goiter (TMNG. The other main causes of thyrotoxicosis were: Graves’ disease (GD (22%, thyroiditis (14.8%, gestational thyrotoxicosis (12.7%, and toxic adenoma (9.6%. The clinical presentation and severity of thyrotoxicosis varied according to the underlying cause. Weight loss was more frequently observed in patients with GD (p=0.0001, while cardiac arrhythmia dominated in patients with TMNG (p=0.0001. Moderate (27% or severe (23.9% thyrotoxicosis was more common in patients with GD than in patients with other forms of thyrotoxicosis (p=0.0001. Discussion: Toxic multinodular goiter is the most common cause of thyrotoxicosis in our region.

    Background: The assessment of liver damage in various disease states relies on a combination of clinical findings, biochemical parameters and invasive tests such as liver biopsy. The ultrasound elastography has emerged as a potential alternative test, providing quantifiable information on the elasticity/stiffness of the examined-tissues. We assessed the performance of ultrasound elastography using real-time Acoustic Radiation Force Imaging (ARFI) technology in evaluating the degree of liver fibrosis in children with and without liver disease. Methods: Children aged 0-18 years, hospitalized in the Emergency Clinical County Hospital Tg. Mures, Romania, between September 15, 2010 and January 15, 2011, were eligible for the study. Four groups were recruited as follow: patients with liver disease in the setting of various malignant disorders, children with non-malignant liver disease, overweight and obese children and healthy controls. The liver tissue elasticity was assessed in each individual using Shear Wave Velocity (SWV). Biochemical tests included transaminase levels. 19 children with chronic liver disease underwent biopsies. SWV was measured globally and separately for the liver-segments 1 and 8. Correlations between the SWV and laboratory test were established using non-parametric Spearman correlation test. Results: A total of 103 children underwent liver ultrasound elastographic assessments. Of these, 39 had malignancies, 19 had various chronic liver diseases, 13 had nonalcoholic fatty liver disease (NAFLD), and 32 were healthy controls. The transaminase values differed significantly between children with liver diseases and controls. In normal controls SWV values in the 1st segment were significantly lower compared to those in the in 8th segment of the liver (p = 0.0216). In the group with hepatic steatosis, the SWV values were statistically higher compared to those in healthy controls. Positive statistical correlations have been established between AST and SWV in the group of children with NAFLD and those with malignancies (p = 0.0032, p = 0.0045). Conclusions: Quantification of liver fibrosis by ARFI method correlates with the histological fibrosis stage in children with chronic liver disease and NAFLD. Clinical applications of this method in the diagnosis of pediatric liver disease deserve further study.

    Kidney biopsy occupies a fundamental position in the management of kidney diseases. There are very few renal pathology studies available in the literature from developing world. This study scrutinized the frequency and clinicopathological relationship of kidney biopsies done at the kidney center from 1997 to 2013 amongst pediatric patients. Kidney allograft biopsy were excluded. The specimen was examined under light microscopy and immunofluorescence while electron microscopy was not done. The study includes 423 patients, mean age was 10.48 ± 4.58 years, males 245 (57.9%) were more than females 178 (42.1%). Nephrotic syndrome 314 (74.2%) was the most common clinical presentation followed by acute nephritic syndrome 35 (8.3%) and acute renal failure 24 (5.7%). Primary glomerulonephritis (PGN) was the most common group of diseases, seen in 360 (85.1%) followed by secondary glomerulonephritis (SGN) in 27 (6.4%) and tubulointerstitial nephritis in 21 (5.0%). Among PGN, minimal change disease (MCD) was the most dominant disease, with 128 (30.3%) cases followed by focal segmental glomerulosclerosis FSGS in 109 (25.8%) and membranous glomerulonephropathy in 27 (6.4%). Lupus nephritis (LN) was the leading cause of glomerular disease in SGN followed by hemolytic uremic syndrome. In conclusion, MCD is the most common histological finding, especially in younger children and FSGS is second to it. SGN is rare, and the most common disease in this category is LN while tubulointerstitial and vascular diseases are infrequent. PMID:27194835

    Full Text Available Background: There is little published literature on the profile of patients with Cushing′s syndrome (CS from India. The aim of this study was to compile data of CS patients treated at this hospital. Materials and Methods: Patients referred to the endocrine services of this hospital for diagnosis/treatment of CS from January 1985 to July 2012 were the subjects for this study. All patients had detailed medical history, physical examination and biochemical and hormonal assays (which changed with availability of tests and changing views. Assays for plasma adrenocorticotropic hormone (ACTH (late 90s, salivary cortisol estimation, IJV sampling for ACTH and corticotrophin releasing hormone stimulation tests were added on later. Imaging included computed tomography (CT, magnetic resonance imaging (since the late 80′s and 68 Ga DOTA-TOC/FDG PET-CT (2008. Results: Three hundred sixty-four patients (250 females, 114 males, age 6 months to 65 years, mean 28 years + 12 years were diagnosed to have CS during this period. Two hundred and ninety-three patients (80.5% were ACTH dependent (CD 215, ectopic ACTH syndrome 22, occult ACTH source 56 while 71 (19.5% were ACTH independent (adrenal carcinoma 36, adenoma 30, primary pigmented nodular adrenal disease 4, AIMAH 1. Pituitary macro adenoma was seen in 14% of the CD cases. The most common presenting complaints were hypertension and diabetes mellitus. A total of 63% patients complained of weight gain while 15% had lost weight. Myopathy, infections, skeletal fractures and psychiatric problems were the other common observations in our patients. Conclusion: The clinical spectrum was broad. CD was the most common cause for CS.

    2016-01-01

    Objective The epidemiology of post-gastric bypass surgery hypoglycemia (PGBH) is incompletely understood. This study aimed to evaluate the risk of PGBH among nondiabetic patients and associated factors. Methods A cohort study of nondiabetic patients who underwent Roux-en-Y gastric bypass (RYGB) was conducted. PGBH was defined by any postoperative record of glucose hypoglycemia, or any medication use for treatment of PGBH. Kaplan-Meier analysis was used to describe PGBH occurrence, log-rank tests, and Cox regression to examine associated factors. Results Of the 1,206 eligible patients, 86% were female with mean age of 43.7 years, mean preoperative BMI of 48.7 kg/m2, and a mean follow-up of 4.8 years. The cumulative incidence of hypoglycemia at 1 and 5 years post-RYGB was 2.7% and 13.3%, respectively. Incidence of PGBH was identified in 158 patients and was associated with lower preoperative BMI (P = 0.048), lower preoperative HbA1c (P = 0.012), and higher 6-month percent of excess body weight loss (%EWL) (P = 0.001). A lower preoperative HbA1c (HR = 1.73, P = 0.0034) and higher 6-month %EWL (HR = 1.96, P = 0.0074) remained independently correlated with increased risk for PGBH in multi-regression analysis. Conclusions The 5-year incidence of PGBH among nondiabetic individuals was 13.3% and was associated with a lower preoperative HbA1c and greater weight loss at 6 months following surgery.

    To evaluate the outcome of RIRS in managing symptomatic calyceal diverticular as a minimally invasive option, we retrospectively reviewed the records of 43 patients who underwent RIRS from 2005 to 2014 for symptomatic calyceal diverticular stones. A month after the initial operation, the success rate was (81.4%, 35 patients) of which 21 (48.83%) patients were stone free and 14 (32.6%) patients had clinically insignificant residual fragments (CIRFs), and 90% patients were symptom free. Eight patients (16.6%) had significant residual fragments (>3 mm), five of them became completely stone free after the second procedure, other three patients were symptom free and underwent a routine follow-up. The final treatment success rate was 93.0%. The initial success rate in the lower calyx was significantly lower than the other calices (P = 0.040). In addition, the association between the stone size and the initial treatment success was significant (P = 0.036). There was no association between any of our other variables and the success rate. The mean first operative time was 60.95 ± 12.43 min (range 34-92). No major complication (Clavien III-V) occurred, although there were five minor complications (11.6%) (Clavien I-II). There were no admissions to intensive care or deaths in our series, the mean hospitalization time was 1.77 ± 0.80 days. The management of calyceal diverticular calculus with RIRS is highly effective and can be accomplished with low morbidity. PMID:26139572

    Full Text Available Background & Aims: Detection of hepatitis C virus RNA in peripheral blood mononuclear cells (PBMC and/or hepatocytes in the absence of HCV RNA in serum, designated as ‘occult HCV infection’, has been a matter of controversy in the recent years. Occult hepatitis C virus (HCV infection has not been investigated in haemodialysis patients. We investigated for the first time the prevalence of occult HCV infection in large cohorts of chronic hemodialysis (CHD patients in a single heamodialysis center at Al-Taif, KSA. Methods: We enrolled 84 CHD patients, whose sera are negative for HCV markers. HCV RNA was tested in PBMC using a sensitive commercial real time assay. In this study, real-time PCR was used to test for the presence of genomic HCV-RNA in peripheral blood mononuclear cells of all of these patients. For comparison, 20 patients on HD with evidence of chronic hepatitis C virus infection were included as a control group. Results: In CHD patients, occult HCV infection, determined by the presence of genomic HCV-RNA in peripheral blood mononuclear cells (PBMNCs, was found in 13.4 % of the patients; 83 % of these patients had ongoing HCV replication, indicated by the presence of HCV-RNA. Patients with occult HCV infection had spent a significantly longer time on heamodialysis and had significantly higher mean alanine aminotransferase levels during the 3 months before study entry. Compared to CHCV patients, those with occult HCV have less elevated bilirubin, AST and ALT. Conclusions: The prevalence of occult HCV infection was moderate in our CHD patients, and it did not appear to be clinically relevant. Further studies in other geographic populations with high HCV endemicity are required to clarify the significance of occult HCV infection in these patient groups. Abbreviations HCV, Hepatitis C Virus ; antibody against HCV; PBMC, peripheral blood mononuclear cells; rRT-PCR, real time reverse transcriptase polymerase chain reaction; CHD, chronic hemodialysis.

    Full Text Available Aim: The aim was to study the impact of nationwide clinical practice guidelines for soft tissue sarcomas (STS, introduced in 1994 and again in 2005 in North Savo, Finland. Methods: We retrospectively reviewed all the patients whose sarcoma was treated by a multidisciplinary team between the years 2000 and 2009 with mean follow-up time of 68 months. The patients were divided into 2 groups according to years: Group A (2000-2005, 72 patients and Group B (2006-2009, 64 patients. Primary outcomes were local recurrence, metastases, and overall survival. Results: Fifty-five percent were men with an average age of 59 years. The most common sarcomas were pleomorphic sarcoma (37% and liposarcoma (26%. Although there were significantly less amputations in Group B (A: 15%, B: 3%, there were more metastases (A: 10%, B: 23% with an overall lower overall survival rate (A: 70%, B: 58% than in Group A. Conversely, Group A had a higher 1st year survival rate (A: 100%, B: 87%. We found that upper limb sarcomas were more likely to be diagnosed with incisional biopsies, but there was no correlation between incisional biopsy and recurrence, metastases or survival. Conclusion: Due to nonadherence of the 2005 national treatment recommendations, there has been no improvement either in management or survival. The importance of educating guidelines to doctors referring patients to specialized units cannot be overemphasized to affect successful management in the treatment of STS.

    AIM: To identify optimum timing to maximize diagnostic yield by capsule endoscopy (CE) in patients with obscure gastrointestinal bleeding (OGIB).METHODS: We identified patients who underwent CE at our institution from August 2003 to December 2009.Patient medical records were reviewed to determine type of OGIB (occult, overt), CE results and complications,and timing of CE with respect to onset of bleeding.RESULTS: Out of 385 patients investigated for OGIB,284 (74%) had some lesion detected by CE. In 222 patients (58%), definite lesions were detected that could unequivocally explain OGIB. Small bowel ulcer/erosions secondary to Crohn's disease, tuberculosis or non-steroidal anti-inflammatory agent use were the commonest lesions detected. Patients with overt GI bleeding for <48 h before CE had the highest diagnostic yield (87%).This was significantly greater (P < 0.05) compared to that in patients with overt bleeding prior to 48 h (68%),as well as those with occult OGIB (59%).CONCLUSION: We established the importance of early CE in management of OGIB. CE within 48 h of overt bleeding has the greatest potential for lesion detection.

  8. Treatment of Common Bile Duct Obstruction by Pancreatic Cancer Using Various Stents: Single-Center Experience

    Purpose: To compare the effectiveness of various means of stenting in patients with biliary obstruction caused by pancreatic cancer in a retrospective analysis. Methods: Sixty-two patients with biliary obstruction due to unresectable pancreatic cancer underwent biliary stenting. On the basis of the findings obtained by percutaneous transhepatic cholangiography(10 patients) and endoscopic retrograde cholangiography (52 patients),the site of obstruction was distal to the hilar confluence,predominantly especially in the middle to lower third of the common bile duct. Polyurethane-covered Wallstents (9 mm in diameter) we reinserted in 13 patients, while uncovered Wallstents (10 mm in diameter)were used in 10 patients and plastic stents (10 Fr and 12 Fr) were used in 39 patients. Results: Stenting was successful in 34 patients (87.2%) treated with plastic stents and in 22 patients(95.7%) treated with Wallstents. Effective biliary drainage was achieved in 32 out of 34 patients (94.1%) treated with plastic stents and in 21 out of 22 patients (95.5%) treated with Wallstents. The cumulative patency rate was significantly higher for the uncovered and covered Wallstents compared to plastic stents, but was not significantly higher for covered than for uncovered Wallstents. Stentocclusion occurred in 23 patients (70%; all by clogging) from the plastic stent group, in two patients (22%; by tumor ingrowth) from the uncovered Wallstent group, and in one patient (9%; by clogging) from the covered Wallstent group. The survival rate showed no significant difference among the three stent groups. Conclusion: The Wallstent is effective for long-term palliation in patients with obstruction caused by pancreatic cancer invading the middle to lower part of the common bile duct. The covered Wallstent can prevent tumor ingrowth, a problem with the uncovered Wallstent. However, it may be necessary to take measures to prevent the migration or clogging of covered Wallstents

    2014-01-01

    Full Text Available To investigate the molecular basis of β-thalassemia intermedia in Northern Iraq and evaluate its management practices, a total of 74 patients from 51 families were enrolled. The patients were clinically and hematologically reevaluated, and had their β-thalassemia mutations characterized, as well as the number of α-globin genes and Xmn I Gγ −158 (C>T polymorphism studied. Out of 14 β-thalassemia mutations identified, the four most common were IVS-I-6 (T>C [33.3%], IVS-II-I (G>A [21.1%], codon 82/83(−G [10.1%], and codon 8 (−AA [8.1%]. The most common contributing factors to the less severe phenotype of thalassemia intermedia were found to be the inheritance of mild β-thalassemia alleles and the Xmn I polymorphism, while concomitant α-thalassemia had a limited role. Several complications were documented including: pulmonary hypertension in 20.4%, diabetes mellitus in 1.4%, hypothyroidism in 2.9%, and heart failure in 2.7%, while no documented cases of venous thrombosis were found. Compared to their counterparts in several Mediterranean countries, it appears that our patients were much less frequently transfused and had a lower proportion of patients who were splenectomized, on iron chelation, or hydroxycarbamide therapy. Such practices require further scrutiny to ensure that a better level of care is provided and that growth retardation, skeletal changes, and other complications are prevented or reduced.

    Full Text Available Objective: To present and discuss the treatment of autoimmune hemolytic anemia (AIHA. Materials and Methods: The medical records of all patients (n=19 diagnosed in a tertiary hematology center between 1999 and 2010 were retrospectively reviewed.Results: Median age at diagnosis of AIHA was 5 years (range: 4 months-17 years. In all, 13 patients had primary (idiopathic AIHA, whereas 2 had primary Evans Syndrome (ES, 2 had autoimmune lymphoproliferative syndrome (ALPS+ES, and 1 had Wiskott-Aldrich syndrome (WAS+AIHA. Among the 13 primary idiopathic AIHA patients, 9 recovered following a 4-8-week course of prednisolone treatment without relapses, whereas 3 patients required a longer course of prednisolone. One AIHA patient that was very resistant to prednisolone recovered after cyclosporine A was added to the treatment. All patients with primary idiopathic AIHA were in remission for a median of 3 years (range: 4 months-10 years at the time this manuscript was written. Among the patients with primary ES, 2 had relapses similar to the ALPS patients. Splenectomy was performed in 1 primary ES patient, who at the time this report was written was also in remission. One ALPS patient required the addition of mycophenolate mofetil due to prednisolone resistance. The WAS patient was treatment resistant and died due to septicemia.Conclusions: Primary AIHA in pediatric patients generally has an acute onset and good response to corticosteroids. Primary or secondary ES has a chronic or relapsing course, and treatment may require other immunosuppressive agents in addition to corticosteroids. Complications of splenectomy must not be underestimated in patients with underlying immunodeficiency. AIHA often causes considerable morbidity and mortality in WAS.
