Prospective evaluation of simplified algorithm for EUS-guided intra-hepatic biliary access and anterograde interventions for failed ERCP

Background

EUS-guided biliary drainage (EUS-BD) is technically challenging but alternative method of therapeutic intervention when ERCP fails.

Objective

Assess the feasibility, safety and risks of EUS-BD with intra-hepatic biliary access and anterograde interventions using an algorithm to increase flexibility of interventions, limit adverse events and improve procedural time.

Design

Prospective observational cohort study.

Patients

21 consecutive patients underwent EUS-BD drainage for failed ERCP.

Main Outcome measures

Technical and clinical success rates with adverse event rate using simplified algorithm.

Results

Patient recruitment from June 2011-October 2013; mean age of 67.4 years, predominantly male (70.5 %) with pancreatic cancer (52.4 %), cholangiocarcinoma (14.3 %), other malignant biliary obstruction (9.5 %) and benign biliary obstruction (23.8 %). Prior interventions included failed ERCP in 18/21 (85.7 %) while 3/21 (14.3 %) had primary EUS-BD. Anterograde cholangiogram was achieved in all patients. Technical success was achieved in 20/21 (95.2 %) with clinical success was achieved in 19/21 (90.4 %). Placement of access wire was across the ampulla in 10/20 (50 %) and into CBD or contra-lateral IHD in 10/20 (50 %). Tract dilatation was accomplished in 17/20 (85 %) but required completion using intra-hepatic needle knife in 3/20 (15 %). Anterograde interventions were performed in 16/20 (80 %) but crossover to rendezvous in 3/20 (15 %) or choledochoduodenostomy 1/20 (5 %). Three patients 3/21 (14.3 %) also had endoscopic duodenal SEMS placement to relieve duodenal obstruction. Two patients (9.5 %) had post-procedural bile leak and pain.

Conclusion

EUS-guided anterograde biliary drainage using the intra-hepatic access route has high technical and clinical success with low adverse rate. We would promote a simplified standardized algorithm, which gives flexibility of direct anterograde interventions.     

Assessing the evolution of publications by Brazilian spine surgeons in the last decade

Purpose

To evaluate the scientific contribution of Brazilian Spine Surgeons not only in number of publications but also in their quality between January 2000 to December 2011.

Methods

A literature search of publications by Brazilian spinal surgeons on topics concerning the spine or spinal cord was performed using an online database; Pubmed.gov. The results were limited to articles published from January 2000 to December 2011. A total of 1,778 articles were identified after a Medline search. After exclusion criteria, the study comprised 206 articles. The quality of the Journals was assessed with IF and the article quality using the Oxford classification.

Results

An increasing number of publications by Brazilian spine surgeons was observed in recent years: 45.1 % of those papers were published during the last 4 years (2008–2011). Clinical studies and case reports were the most frequent types of article published (37.5 vs 31.1 %). An increasing number of Brazilian publications in non-Brazilian journals has been observed in recent years (linear-by-linear association: 5.449, P = 0.020). The Arquivos de Neuro-Psiquiatria was the most frequent journal in which the papers were published (N = 67, 32 %). The IF of the publications varied from 0.021 to 8.017. The analysis of quality of the articles using the Oxford classification demonstrated that most of them provided LOE 4 (N = 113, 54.9 %) or 5 (N = 45, 21.8 %).

Conclusions

There have been an increasing number of publications by Brazilian spine surgeons in recent years and the quality of the articles published has improved. Also the number of publications by Brazilians in non-Brazilian journals has increased in recent years.     

What is the role of the sleeve gastrectomy in the surgical treatment of morbid obesity?

Background

Laparoscopic sleeve gastrectomy (SG) is a relatively new procedure that is gaining wide acceptance and represents an innovative new approach to the surgical management of morbid obesity. Our purpose is to evaluate the SG as a surgical bariatric procedure.

Methods

We conducted a literature review on “PubMed” based on all publications related to SG since 2000 to July 30, 2014.

Results

The complication rate after SG varies in the literature, ranging from 0 to 29 %. The most feared complication after SG is leakage on the staple line, occurring in 0–7 % of cases. The mortality rate reported varies between 0 and 3.3 %. No consensus has developed on the types of stapling used or the methods of strengthening the staple line. SG may aggravate and be responsible for gastroesophageal reflux disease (GERD). SG improves comorbidities in more than 50 % after 5 years.

Conclusions

SG can be proposed as a surgical technique at first intension in patients not having GERD.     

Morbidity of Loop Ileostomy Closure after Restorative Proctocolectomy for Ulcerative Colitis and Familial Adenomatous Polyposis: a Systematic Review

Background

Temporary loop ileostomy is a routine procedure to reduce the morbidity of restorative proctocolectomy. However, morbidity of ileostomy closure could reduce the benefit of this concept. The objective of this systematic review was to assess the risks of ileostomy closure after restorative proctocolectomy for ulcerative colitis or familial adenomatous polyposis.

Materials and Methods

Publications in English or German language reporting morbidity of ileostomy closure after restorative proctocolectomy were identified by Medline search. Two hundred thirty-two publications were screened, 143 were assessed in full-text, and finally 26 studies (reporting 2146 ileostomy closures) fulfilled the eligibility criteria. Weighted means for overall morbidity and mortality of ileostomy closure, rate of redo operations, anastomotic dehiscence, bowel obstruction, wound infection, and late complications were calculated.

Results

Overall morbidity of ileostomy closure was 16.5 %, there was no mortality. Redo operations for complications were necessary in 3.0 %. Anastomotic dehiscence occurred in 2.0 %. Postoperative bowel obstruction developed in 7.6 %, with 2.9 % of patients requiring laparotomy for this complication. Wound infection rate was 4.0 %. Hernia or bowel obstruction as late complications developed in 1.9 and 9.4 %, respectively.

Conclusion

The considerable morbidity of ileostomy reversal reduces the overall benefit of temporary fecal diversion. However, ileostomy creation is still recommended, as it effectively reduces the risk of pouch-related septic complications.     

Partnership for Sustainability in Cardiac Surgery to Address Critical Rheumatic Heart Disease in Sub-Saharan Africa: The Experience from Rwanda

Importance

Rheumatic heart disease (RHD) in the developing world results in critical disability among children, adolescents, and young adults—marginalizing a key population at its peak age of productivity. Few regions in sub-Saharan Africa have independently created an effective strategy to detect and treat streptococcal infection and mitigate its progression to RHD.

Objective

We describe a unique collaboration, where the Rwanda Ministry of Health, the Rwanda Heart Foundation, and an expatriate humanitarian cardiac surgery program have together leveraged an innovative partnership as a means to expand Rwanda’s current capacity to address screening and primary prevention, as well as provide life-saving cardiac surgery for patients with critical RHD.

Evidence review

Interviews with key personnel and review of administrative records were conducted to obtain qualitative and quantitative data on the recruitment of clinical personnel, procurement of equipment, and program finances. The number of surgical cases completed and the resultant clinical outcomes are reviewed.

Findings

From 2008 to 2013, six annual visits were completed. A total of 128 prosthetic valves have been implanted in 86 complex patients in New York Heart Association (NYHA) class III or IV heart failure, with excellent clinical outcomes (5 % 30-day mortality). Postoperative complications included a cerebrovascular accident (n = 1) and hemorrhage, requiring reoperation (n = 2). All procedures were performed with participation of local personnel.

Conclusions and relevance

This strategy provides a reliable and consistent model of sophisticated specialty care delivery; inclusive of patient-centered cardiac surgery, mentorship, didactics, skill transfer, and investment in a sustainable cardiac program to address critical RHD in sub-Saharan Africa.     

Frey’s Pancreaticojejunostomy in Tropical Pancreatitis: Assessment of Quality of Life. A Prospective Study

Introduction

Tropical pancreatitis is a form of chronic pancreatitis originally described in the tropics. Prospective studies in Western countries have shown improved quality of life (QOL) following surgery in alcoholic chronic pancreatitis. In studies on Frey’s pancreaticojejunostomy for tropical pancreatitis, improvement in pain was considered the endpoint, and there is a paucity of data in the literature with regard to QOL with tropical pancreatitis following surgery.

Objective

Our objective was to prospectively analyze the outcome of Frey’s pancreaticojejunostomy in tropical pancreatitis and health-related QOL following surgery by administering the Short Form 36-item health survey (SF-36).

Materials and methods

A total of 25 patients underwent Frey’s pancreaticojejunostomy between 2010 and 2012 and were included in the study; data were collected prospectively. The visual analog scale (VAS) for pain and the SF-36 form were used to record health-related QOL preoperatively, and at 3 and 12 months post-surgery, comparing the same with the general population.

Results

Patients with tropical pancreatitis experience poor QOL (26.71 ± 15.95) compared with the general population (84.54 ± 12.42). Post-operative QOL scores (78.54 ± 15.84) were better than the pre-operative scores (26.71 ± 15.95) at 12-month post-surgery follow-up. The VAS score for pain improved at 12 months post-surgery (1.58 ± 1.41 vs. 8.21 ± 1.64). Two of the three patients (12.5 %) who had diabetes were free from anti-diabetes medication at 12 months post-surgery. Steatorrhea was seen in five patients (20.8 %) before surgery and increased to eight (33.3 %) at 12 months post-surgery. Mean body weight increased from 45.75 kg pre-operatively to 49.25 kg at 12 months post-operatively.

Conclusions

Frey’s pancreaticojejunostomy effectively reduces pain in tropical pancreatitis, with significant improvement in health-related QOL, which is comparable with the general population in most aspects.     

Effect of different episiotomy techniques on perineal pain and sexual activity 3 months after delivery

Introduction and hypothesis

The effect of different episiotomy techniques on pain perception 3 months after delivery is unknown. Study aims were to explore the association between different episiotomy techniques and perineal pain 3 months after delivery and to assess female sexual activity in relation to episiotomy technique.

Methods

This is a prospective observational study, designed to investigate short- and long-term complications of different episiotomy techniques. All 300 participants were recruited and clinically examined during their postpartum hospital stay in order to evaluate episiotomy performance. A 3-month follow-up questionnaire addressing pain, sexual activity, and puerperal wound infection was distributed to 208 women who had scored perineal pain in a personal interview the first day after delivery.

Results

A response rate of 87.7 % was obtained. We found no difference in pain score distribution by Visual Analogue Scale (VAS) when comparing midline, mediolateral, and lateral episiotomy techniques (p?=?0.32) or between midline and lateral incision points (p?=?0.58). Dyspareunia was reported by 33 out of 179 women, but no difference between episiotomy techniques (p?=?0.90), or between episiotomy incision points (p?=?0.14), was found. Perineal wound infection was reported by 9.5 %, but there was no significant difference between episiotomy techniques (p?=?0.73).

Conclusions

No difference was found in perineal pain perception 3 months postpartum between different episiotomy techniques or when comparing midline and lateral incision points. Dyspareunia was not associated with any particular episiotomy technique or incision point.     

Inguinal hernia repair using a synthetic long-term resorbable mesh: results from a 3-year prospective safety and performance study

Purpose

Conventional meshes for hernia repair and abdominal wall reinforcement are usually made from polypropylene, polyester or other synthetic plastic materials known to promote foreign body reactions and a state of chronic inflammation that may lead to long-term complications. A novel approach is to use long-term resorbable implants like TIGR^® Matrix Surgical Mesh. Preclinical studies have shown that this mesh maintains mechanical integrity beyond the point in time where newly formed tissue is capable of carrying the abdominal loads.

Methods

This was a first-in-man, prospective, pilot study performed during 2009, at two sites in Sweden. Forty patients with primary inguinal hernias were enrolled for Lichtenstein repair using TIGR^® Matrix Surgical Mesh. The primary endpoint was safety as assessed by monitoring the incidence of adverse events and serious adverse events (SAEs) both related and unrelated to the mesh. The secondary endpoint was pain or discomfort. Visual Analogue Scale (VAS) 0–10 and Inguinal Pain Questionnaire were used for scoring pain and discomfort. Included patients have been followed for 36 months using ultrasound in combination with clinical examination.

Results

All patients followed a normal early postoperative course. After 12 months no SAEs were reported. None of the patients with an isolated lateral inguinal hernia (LIH) had developed a recurrence but 4 (44 %) with medial and 4 (33 %) with combined hernias had recurred at 36-month follow-up. After 3-year follow-up none of the patients with LIH reported pain in the VAS-form and none of those patients could feel the sensation of a mesh in their groin. In the total study population 5 (16 %) patients experienced chronic pain in the form of mild sporadic pain and 3 (9.7 %) patients could feel the sensation of a mesh in their groin.

Conclusion

The use of a synthetic long-term resorbable mesh (TIGR^® Matrix Surgical Mesh) in Lichtenstein repair was found to be safe, without recurrences, and promising regarding pain/discomfort at 3-year follow-up in patients with LIH. However, patients with medial and combined inguinal hernias had high recurrence rates.     

The comparison of instrumented and non-instrumented fusion in the treatment of lumbar spondylolisthesis: a meta-analysis

Purpose

This meta-analysis compared whether fusion with or without instrumentation to treat this disease differed with respect to patient-centered outcomes.

Methods

Medline, Cochrane, EMBASE, Google Scholar data bases were searched for randomized control trials that investigated patients with severe chronic lower back pain resulting from localized lumbar or lumbosacral instability caused by either isthmic spondylolisthesis or degenerative spondylolisthesis. Included randomized studies reported quantitative outcomes for low back pain and functional recovery. The primary outcome was the improvement of function and the secondary outcomes were the improvement of pain, patients’ satisfactory level, and the fusion rate.

Results

A significantly lower function change in patients with instrumented compared with non-instrumented from baseline (pooled standardized mean difference; ?1.02 (95 % CI ?1.76 to ?0.27); Z ?2.67; (P = 0.008)]. There was no significant pain change for patients with instrumented compared with that of non-instrumented from baseline [pooled standardized mean difference; ?0.07 (95 % CI ?1.25 to 1.12); Z ?0.11; (P = 0.913)]. There was no significant difference in satisfactory level for patients with instrumented compared with that of non-instrumented [pooled OR; 2.36 (95 % CI 0.91–6.11); Z 1.76; (P = 0.078)]. There was significantly higher fusion rate for patients with instrumented compared with that of non-instrumented [pooled OR; 3.28 (95 % CI 2.22–4.85); Z 5.96; (P < 0.001)].

Conclusions

This meta-analysis found that inclusion of fusion surgery with instrumentation provided no benefit as evaluated by patient-reported outcomes in patients with lumbar spondylolisthesis.

Level of evidence

Not applicable.     

Stand-alone ALIF with integrated intracorporeal anchoring plates in the treatment of degenerative lumbar disc disease: a prospective study on 65 cases

Purpose

ALIF with cages is expected to restore disc height and stabilize the spine promoting fusion, while avoiding damage attributed to rod-pedicle screw fixation. However, it may be related to an increased risk of fusion failure and subsidence. A prospective study was conducted by five investigators across three centers to confirm performance of a PEEK cage for stand-alone ALIF in the treatment of lumbar degenerative disc disease (DDD).

Methods

Sixty-five patients, with back ± leg pain, requiring surgery for DDD, were included. Efficacy and safety were evaluated at 6 weeks, 3, 6, and 12 months post-operatively. Fusion and subsidence were assessed through CT-images at 12-month follow-up. Disc height was measured. Clinical outcomes included back and leg pain (VAS), disability (Oswestry Disability Index), Quality of Life (Short-Form 36), and adverse events.

Results

The fusion and the subsidence rates were 96.3 and 2.0 %, respectively. ALIF surgery restored anterior and posterior disc height compared to baseline. There were no device-related serious adverse events, and no revision surgeries. Clinical outcomes improved significantly through 12-month follow-up.

Conclusion

Safety and efficacy of this stand-alone cage with integrated intracorporeal plates was confirmed through 12 months for treatment of degenerative conditions. The design of the cage and plates may contribute to the decreased subsidence rate observed.     

The effect of selective serotonin reuptake inhibitor (SSRI) on pain-related behavior in a rat model of neuropathic pain

Introduction

Some antidepressants are effective for treating neuropathic pain independent of any effect on depression. Selective serotonin reuptake inhibitors (SSRIs) are one of the potential agents to treat neuropathic pain. The aims of this study were to compare the effects of SSRI and non-steroidal anti-inflammatory drugs (NSAIDs) on pain-related behavior and expression of cytokines in a rat model of neuropathic pain.

Materials and methods

Spinal surgery was performed to apply nucleus pulposus (NP) to the dorsal root ganglion (DRG). NP animals were treated with saline (NP + S), meloxicam (NP + M), or low-dose or high-dose paroxetine (NP + PL and NP + PH), respectively. Behavioral testing was performed to investigate the mechanical withdrawal thresholds. The numbers of TNF-immunoreactive (IR) neurons in the DRG and of Iba1-IR microglia in the spinal cord (SC) were evaluated using immunohistochemistry. Expression of TNF in the DRG was examined using Western blots.

Results

The thresholds on days 14, 21, and 28 were higher in the drug-treated animals than in the NP + S group (p < 0.05). The number of TNF-IR neurons in DRGs from the NP + M group increased on day 2 and decreased on day 7, and TNF expression in DRGs was significantly higher in the NP + S group than in the NP + M group on days 7, 14. The number of Iba1-IR microglia in the SC was significantly higher in the NP + S group than in the NP + M, NP + PL, and NP + PH groups on days 7 and 14.

Conclusion

An antidepressant might be a potential agent to treat lumbar disc herniation as well as NSAIDs.     

Laparoscopic resection of large gastric GISTs: feasibility and long-term results

Background

Laparoscopy is the procedure of choice for the resection of gastric Gastrointestinal stromal tumors (GISTs) smaller than 2 cm; there is still debate regarding the most appropriate operative approach for larger GISTs. The aims of this study were to evaluate the safety and long-term efficacy of laparoscopic resection of gastric GISTs larger than 2 cm.

Methods

Between 2007 and 2011, we prospectively enrolled all patients affected by gastric GIST larger than 2 cm. Exclusion criteria for the laparoscopic approach were the presence of metastases and the absence of any involvement of the esophago-gastric junction, the pyloric canal, or any adjacent organ. Final diagnosis of GIST was confirmed by histological and immunohistochemical analysis. Follow-up assessment included abdominal CT scans every 6 months for the first 2 years and yearly thereafter.

Results

Twenty-four consecutive patients were enrolled. Twenty-one patients (87.5 %) were symptomatic. The most common symptoms were gastrointestinal bleeding and abdominal pain. The mean tumor size was 5.51 cm (range 2.5–12.0 cm). GISTs were located in the lesser curvature in five cases (20.8 %), in the greater curvature in seven cases (29.1 %), in the posterior wall in one case (4.1 %), in the anterior wall in eight cases (33.3 %), and in the fundus in 3 cases (12.5 %). Laparoscopic resection was possible in all cases and took on average of 55 min (range 30–105 min). Median blood loss was 24 ml. No major intraoperative complications were observed. Mortality rate was 0 %. Median postoperative stay was 3 days. No patients were lost to follow-up. No recurrences occurred after a median follow-up period of 75 months.

Conclusion

Although larger randomized controlled trials comparing different surgical strategies for large gastric GISTs are warranted, our study supports the evidence that laparoscopic resection of gastric GISTs is feasible, safe, and effective on long-term clinical outcome even for lesions up to 12 cm.     

Transcystic or Transductal Stone Extraction during Single-Stage Treatment of Choledochocystolithiasis: A Systematic Review

Background

Choledochocystolithiasis can be managed by endoscopic retrograde cholangiopancreaticography (ERCP) or laparoscopically by transcystic (TC) or transductal (TD) stone extraction.

Objective

The aim of this study was to systematically review safety and effectiveness of combined endoscopic/laparoscopic management versus total laparoscopic management for choledochocystolithiasis with specific emphasis on TC versus TD stone extraction.

Methods

MEDLINE/PubMed, EMBASE, the Cochrane Library, and clinicaltrials.gov were searched systematically to identify trials on combined endoscopic/laparoscopic and total laparoscopic management for choledochocystolithiasis. Laparoscopic common bile duct (CBD) exploration was divided into TD and TC approach. Primary outcomes were successful stone clearance from CBD, postoperative/procedural morbidity, and mortality.

Results

Eight randomized trials with 965 patients were included. Successful bile duct clearance varied between 52.6 and 97 % in the ERCP groups, 80.4 and 100 % in the TC groups, and 58.3 and 100 % in the TD groups. There were more bile leaks after TD stone extraction (11 %) than after ERCP (1 %) and TC stone extraction (1.7 %). Total morbidity varied between 9.1 and 38.3 % in the ERCP groups, 7 and 10.5 % in the TC groups, and 18.4 and 26.7 % in the TD groups. Methodological and statistical heterogeneity among the trials precluded a meaningful meta-analysis.

Conclusion

Stone clearance rates are comparable between the three modalities, but TD stone extraction is associated with a higher risk of bile leaks and should only be performed by highly experienced surgeons. TC stone extraction seems a more accessible technique with lower complication rates. If unsuccessful, per- or postoperative endoscopic stone extraction is a viable option.     

A multidisciplinary rehabilitation programme improves disability,kinesiophobia and walking ability in subjects with chronic low back pain: results of a randomised controlled pilot study

Purpose

To evaluate the effect of a multidisciplinary rehabilitation programme on disability, kinesiophobia, catastrophizing, pain, quality of life and gait disturbances in patients with chronic low back pain (CLBP).

Methods

This was a parallel-group, randomised, superiority-controlled pilot study in which 20 patients were randomly assigned to a programme consisting of motor training (spinal stabilising exercises plus usual-care) and cognitive–behavioural therapy (experimental group, 10 subjects) or usual-care alone (control group, 10 subjects). Before treatment, 8 weeks later (post-treatment), and 3 months after the end of treatment, the Oswestry Disability Index, the Tampa Scale for Kinesiophobia, the Pain Catastrophizing Scale, a pain numerical rating scale, and the Short-Form Health Survey were assessed. Spatio-temporal gait parameters were also measured by means of an electronic walking mat. A linear mixed model for repeated measures was used for each outcome measure.

Results

The programme had significant group (p = 0.027), time (p < 0.001), and time-by-group interaction (p < 0.001) effects on disability, with the experimental group showing an improvement after training of about 61 % (25 % in the control group). The analyses of kinesiophobia, catastrophizing, and the quality of life also revealed significant time, group, and time-by-group interaction effects in favour of the experimental group, and there was a significant effect of time on pain. Both groups showed a general improvement in gait parameters, with the experimental group increasing cadence significantly more.

Conclusion

The multidisciplinary rehabilitation programme including cognitive–behavioural therapy was superior to the exercise programme in reducing disability, kinesiophobia, catastrophizing, and enhancing the quality of life and gait cadence of patients with CLBP.     

Implementing a Screening Tool for Identifying Patients at Risk for Hereditary Breast and Ovarian Cancer: A Statewide Initiative

Background

The Georgia Breast Cancer Genomic Health Consortium is a partnership created with funding from the Centers for Disease Control and Prevention (CDC) to the Georgia Department of Public Health to reduce cancer disparities among high-risk minority women. The project addresses young women at increased risk for hereditary breast and ovarian cancer (HBOC) syndrome through outreach efforts.

Methods

The consortium provides education and collects surveillance data using the breast cancer genetics referral screening tool (B-RST) available at www.BreastCancerGeneScreen.org. The HBOC educational protocol was presented to 73 staff in 6 public health centers. Staff used the tool during the collection of medical history. Further family history assessments and testing for mutations in the BRCA1/2 genes were facilitated if appropriate.

Results

Data was collected from November 2012 through December 2013, including 2,159 screened women. The majority of patients identified as black/African American and were 18–49 years old. Also, 6.0 % (n = 130) had positive screens, and 60.9 % (n = 67) of the 110 patients who agreed to be contacted provided a detailed family history. A total of 47 patients (42.7 %) met National Comprehensive Cancer Network guidelines when family history was clarified. Fourteen (12.7 %) underwent genetic testing; 1 patient was positive for a BRCA2 mutation, and 1 patient was found to carry a variant of uncertain significance.

Conclusions

The introduction of genomics practice within public health departments has provided access to comprehensive cancer care for uninsured individuals. The successful implementation of the B-RST into public health centers demonstrates the opportunity for integration of HBOC screening into primary care practices.     

Dialysis-treated end-stage kidney disease in Libya: epidemiology and risk factors

Purpose

End-stage kidney disease (ESKD) is now a worldwide pandemic. In concert with this, ESKD in Libya has also increased exponentially in recent decades. This review aims to define the magnitude of and risks for this ESKD epidemic among Libyans as there is a dearth of published data on this subject.

Methods

A systematic review was conducted by searching PubMed, EMBASE and Google scholar databases to identify all relevant papers published in English from 2003 to 2012, using the following keywords: end stage, terminal, chronic, renal, kidney, risk factors, Arab, North Africa and Libya.

Results

In 2003, the reported incidence of ESKD and prevalence of dialysis-treated ESKD in Libya were the same at 200 per million population (pmp). In 2007, the prevalence of dialysis-treated ESKD was 350 pmp, but the true incidence of ESKD was not available. The most recent published WHO data in 2012 showed the incidence of dialysis-treated ESKD had risen to 282 pmp and the prevalence of dialysis-treated ESKD had reached 624 pmp. The leading causes of ESKD were diabetic kidney disease (26.5 %), chronic glomerulonephritis (21.1 %), hypertensive nephropathy (14.6 %) and congenital/hereditary disease (12.3 %). The total number of dialysis centers was 40 with 61 nephrologists. Nephrologist/internist to patient ratio was 1:40, and nurse to patient ratio was 1:3.7. Only 135 living-related kidney transplants had been performed between 2004 and 2007. There were no published data on most macroeconomic and renal service factors.

Conclusions

ESKD is a major public health problem in Libya with diabetic kidney disease and chronic glomerulonephritis being the leading causes. The most frequent co-morbidities were hypertension, obesity and the metabolic syndrome. In addition to provision of RRT, preventive strategies are also urgently needed for a holistic integrated renal care system.     

Publikationsleistungen der Universitätskliniken für Anästhesiologie

Aim

This study assessed the publication performance of university departments of anesthesiology in Austria, Germany and Switzerland. The number of publications, original articles, impact factors and citations were evaluated.

Material and methods

A search was performed in PubMed to identify publications related to anesthesiology from 2001 to 2010. All articles from anesthesiology journals listed in the fields of anesthesia/pain therapy, critical care and emergency medicine by the “journal citation report 2013” in Thomson Reuters ISI web of knowledge were included. Articles from non-anaesthesiology journals, where the stem of the word anesthesia (anes*, anaes*, anäst*, anast*) appears in the affiliation field of PubMed, were included as well. The time periods 2001–2005 and 2006–2010 were compared. Articles were allocated to university departments in Austria, Germany and Switzerland via the affiliation field.

Results

A total of 45 university departments in Austria, Germany and Switzerland and 125,979 publications from 2,863 journals (65 anesthesiology journals, 2,798 non-anesthesiology journals) were analyzed. Of the publications 23?% could not be allocated to a given university department of anesthesiology. In the observation period the university department of anesthesiology in Berlin achieved most publications (n?=?479) and impact points (1,384), whereas Vienna accumulated most original articles (n?=?156). Austria had the most publications per million inhabitants in 2006-2010 (n=50) followed by Switzerland (n=49) and Germany (n=35). The number of publications during the observation period decreased in Germany (0.5?%), Austria (7?%) and Switzerland (8?%). Tables 2 and 4–8 of this article are available at Springer Link under Supplemental.

Conclusions

The research performance varied among the university departments of anesthesiology in Germany, Austria and Switzerland whereby larger university departments, such as Berlin or Vienna published most. Publication output in Germany, Austria and Switzerland has decreased. Data processing in PubMed should be improved.
