Fundus rotation gastroplasty: rationale, technique and results,

DISEASES OF THE ESOPHAGUS, Issue 2 2002
W. Uhl
SUMMARY. Anastomotic leakage is the main factor (up to 30%) for postoperative morbidity and mortality after esophageal resection. Compromised anastomotic perfusion after dissection of supplying vessels for gastric tube formation and tension on the suture line are the two main reasons for anastomotic insufficiency. To prevent anastomotic leakage, a new technique for gastric tube formation after esophageal resection has been developed and introduced into surgical practice: the fundus rotation gastroplasty (FRG). The following paper summarizes rationale, technique and early results of this new technique. It is shown that the FRG is a safe and effective technique for esophageal reconstruction and offers important advantages over conventional gastroplasties: (i) the improved perfusion of the oral part of the tube; (ii) the gain of tube length allowing for a safer performance of even pharyngeal anastomosis as shown by the low insufficiency rate of 9%; and (iii) the increase of remaining gastric reservoir supporting physiologic stomach and gut function. Therefore, the FRG seems to be an alternative and safe method for esophageal reconstruction, especially for high anastomotic locations. [source]


History of hemodialyzers' designs

HEMODIALYSIS INTERNATIONAL, Issue 2 2008
Zbylut J. TWARDOWSKI
Abstract Accumulation of knowledge requisite for development of hemodialysis started in antiquity and continued through Middle Ages until the 20th century. Firstly, it was determined that the kidneys produce urine containing toxic substances that accumulate in the body if the kidneys fail to function properly; secondly, it was necessary to discover the process of diffusion and dialysis; thirdly, it was necessary to develop a safe method to prevent clotting in the extracorporeal circulation; and fourthly, it was necessary to develop biocompatible dialyzing membranes. Most of the essential knowledge was acquired by the end of the 19th century. Hemodialysis as a practical means of replacing kidney function started and developed in the 20th century. The original hemodialyzers, using celloidin as a dialyzing membrane and hirudin as an anticoagulant, were used in animal experiments at the beginning of the 20th century, and then there were a few attempts in humans in the 1920s. Rapid progress started with the application of cellophane membranes and heparin as an anticoagulant in the late 1930s and 1940s. The explosion of new dialyzer designs continued in the 1950s and 1960s and ended with the development of capillary dialyzers. Cellophane was replaced by other dialyzing membranes in the 1960s, 1970s, and 1980s. Dialysis solution was originally prepared in the tank from water, electrolytes, and glucose. This solution was recirculated through the dialyzer and back to the tank. In the 1960s, a method of single-pass dialysis solution preparation and delivery system was designed. A large quantity of dialysis solution was used for a single dialysis. Sorbent systems, using a small volume of regenerated dialysis solution, were developed in the mid 1960s, and continue to be used for home hemodialysis and acute renal failure. At the end of the 20th century, a new closed system, which prepared and delivered ultrapure dialysis solution preparation, was developed. This system also had automatic reuse of lines and dialyzers and prepared the machine for the next dialysis. This was specifically designed for quotidian home hemodialysis. Another system for frequent home hemodialysis or acute renal failure was developed at the turn of the 21st century. This system used premanufactured dialysis solution, delivered to the home or dialysis unit, as is done for peritoneal dialysis. [source]


Irreversible electroporation of the pancreas in swine: a pilot study

HPB, Issue 5 2010
Kevin P. Charpentier
Abstract Background:, Irreversible electroporation (IRE) is a novel, non-thermal method of tissue ablation using short pulses of high-voltage DC current to ablate tissue. Methods:, Irreversible electroporation of the pancreas was performed in four domestic female swine using two monopolar probes spaced 9,15 mm apart. Ninety pulses of 1500 V/cm were delivered for each ablation. Results:, All animals survived for their designated times of 2 h (n= 1), 2 days (n= 1) and 14 days (n= 2), respectively. No procedure-related complications occurred. Three animals in which probes had been spaced at intervals of 10 ± 1 mm showed evidence of irreversible ablation, with ablation height ranging from <10 mm to 21 mm and ablation width ranging from <10 mm to 16 mm by gross appearance and triphenyltetrazolium chloride (TTC) staining. The only animal in which probes had been spaced at intervals of 15 mm did not show evidence of irreversible ablation at 2 weeks. This may be secondary to the wider probe spacing and relatively low voltage, which results in a mostly reversible form of electroporation without cell death. Conclusions:, Irreversible electroporation appears to be a safe method for pancreas tissue ablation. Staining with TTC can predict the zone of IRE ablation within 2 h of treatment. [source]


Cognition following bilateral deep brain stimulation surgery of the subthalamic nucleus for Parkinson's disease

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 5 2009
Casey H. Halpern
Abstract Objective Parkinson's disease (PD) is a neurodegenerative disorder characterized by significant motor dysfunction and various non-motor disturbances, including cognitive alterations. Deep brain stimulation (DBS) is an increasingly utilized therapeutic option for patients with PD that yields remarkable success in alleviating disabling motor symptoms. DBS has additionally been associated with changes in cognition, yet the evidence is not consistent across studies. The following review sought to provide a clearer understanding of the various cognitive sequelae of bilateral subthalamic nucleus (STN) DBS while taking into account corresponding neuroanatomy and potential confounding variables. Design A literature search was performed using the following inclusion criteria: (1) at least five subjects followed for a mean of at least 3 months after surgery; (2) pre- and postoperative cognitive data using at least one standardized measure; (3) adequate report of study results using means and standard deviations. Results Two recent meta-analyses found mild post-operative impairments in verbal learning and executive function in patients who underwent DBS surgery. However, studies have revealed improved working memory and psychomotor speed in the ,on' vs ,off' stimulation state. A deficit in language may be a consequence of the surgical procedure. Conclusions While cognitive decline has been observed in some domains, our review of the data suggests that STN DBS is a worthwhile and safe method to treat PD.

A randomised controlled trial of the effects of cryotherapy on pain, eyelid oedema and facial ecchymosis after craniotomy

JOURNAL OF CLINICAL NURSING, Issue 21 2009
Yong Soon Shin
Aim., To identify the effects of cryotherapy on patient discomfort following craniotomy. Background., Following craniotomy, many patients suffer from unexpected discomfort, including pain, eyelid oedema and ecchymosis. Cryotherapy is regarded as a safe method for managing these postcraniotomy problems. Design., Randomised controlled trial. Methods., A total of 97 Korean patients who underwent elective supratentorial craniotomy were randomly assigned to a cryotherapy or a control group. In the cryotherapy group, ice bags were applied to surgical wounds, and cold gel packs were applied to periorbital areas, for 20 minutes per hour, beginning three hours postoperatively and for three days thereafter. The level of patient pain was measured using the visual analogue scale while the eyelid oedema was measured using the Kara & Gokalan's scale. Ecchymosis was also classified according to its extent. Results., The level of pain three hours after craniotomy was similar in the cryotherapy and control groups (57·9 vs. 58·7). Three days after surgery, pain had significantly decreased in the cryotherapy group (p = 0·021). After adjusting diagnosis by analysis of covariance (ancova), pain score did not differ significantly between the two groups. The mean eyelid oedema scores were lower in the cryotherapy group than in the control group (0·59 vs. 2·29, p < 0·001), with ancova showing that cryotherapy had a significant effect on eyelid oedema (p < 0·001). Pain (p = 0·047) and eyelid oedema (p < 0·001) in the cryotherapy group were significantly decreased over time. Ecchymosis were significantly less frequent in the cryotherapy (11/48, 22·9%) than in the control (26/49, 53·1%) group (p = 0·003). Logistic regression analysis showed that cryotherapy affected ecchymosis (p = 0·001). Conclusion., These results indicate that cryotherapy can control pain, eyelid oedema and facial ecchymosis after craniotomy. Relevance to clinical practice., Cryotherapy, which is both convenient and cost-effective, can be used to prevent postoperative discomforts in a clinical setting. [source]


A randomised, controlled trial of the effects of an energy-dense supplement on energy intake, appetite and blood lipids in malnourished community-based elderly patients

JOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 4 2008
G.P. Hubbard
Background:, Disease-related malnutrition is common in the elderly and if left untreated may have severe consequences (Stratton & Elia, 2003). One of the strategies used to combat malnutrition is the use of high-energy, low-volume [18.8 kJ mL,1 (4.5 kcal ml,1)] nutritional supplements. This study aimed to investigate the effects of an energy dense supplement on energy intake, appetite and blood lipids in elderly patients at risk of malnutrition. Methods:, In this randomised, controlled, parallel study, 42 community-based patients (mean (SD) age: 84 (7.0) years, mean body mass index (BMI): 20.9 (3.5) kg m,2), identified as being at medium or high risk of malnutrition [Malnutrition Universal Screening Tool (MUST) (Elia, 2003)] were randomised (using standard randomisation methods) to receive either; (i) 1674 kJ day,1 (400 kcal day,1) (in 3 × 30 mL doses) of an energy-dense supplement (Calogen, Nutricia®) (n = 19) or (ii) dietary advice in the form of a standardised dietary advice sheet (n = 23), for 4 weeks. Energy intake, appetite, blood lipids [i.e. total cholesterol, low density lipoprotein (LDL) cholesterol (subset analysis only)], body weight, gastro-intestinal tolerance, product compliance and product acceptability were assessed during the 4 week study. Results are presented as mean (SD). Paired t -test and one way anova statistical analyses were undertaken using SPSS v15. Ethical approval for this study was obtained from the appropriate committee. Results:, Supplementation with the energy dense supplement significantly increased mean total daily energy intake by +1736 kJ (+415 kcal, P = 0.009) from 6456 (2330) kJ [1543 (557) kcal] to 8192 (1477) kJ [1958 (353) kcal], with no significant effect on voluntary food intake or appetite scores (for hunger, fullness and desire to eat). In the dietary advice group, although mean total daily energy intake was also significantly increased by +1105 kJ (+264 kcal, P = 0.026) from 5623 (2107) kJ [1344 (503) kcal] to 6728 (2029) kJ [1608 (485) kcal], it was significantly lower than in the energy dense group [-1464 kJ (-350 kcal), P = 0.012] at week 4. Both energy-dense and dietary advice groups maintained weight during the study. No significant adverse effects on blood lipid concentrations were observed in either group, with a significant decrease in total cholesterol concentrations [from 4.26 (1.0) mM to 3.96 (0.8) mM, P = 0.03] and LDL cholesterol concentrations [from 2.32 (0.6) mM to 2.06 (0.5) mM, P = 0.03] in the energy dense group (subset analysis, n = 9). Both supplementation with energy dense supplement and dietary advice were well tolerated with no gastro-intestinal side effects. The energy dense supplement was well accepted with >80% of patients rating it as pleasant and convenient, with an enjoyable taste. Compliance with the energy dense supplement was high, with 95% of patients consuming the recommended dose of 3 × 30 mL throughout the study. Discussion:, This study in elderly patients with or at risk of malnutrition suggests that the energy dense supplement is effective in significantly improving total intakes of energy with no suppression of appetite or voluntary dietary intake, enabling patients to maintain weight and that the energy dense supplement is well tolerated and accepted, with excellent compliance and no adverse effects on blood lipids. Conclusions:, This randomised controlled trial suggests that an energy-dense supplement is an effective, well tolerated and safe method of providing energy supplementation for the management of elderly patients with or at risk of malnutrition in clinical practice.

Prolonged activated partial thromboplastin time in thromboprophylaxis with unfractionated heparin in patients undergoing cesarean section

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2010
Shigeki Matsubara
Abstract Aim:, Hemorrhage is an important complication of heparin-thromboprophylaxis after surgery. We attempted to clarify the incidence rate of prolonged activated partial thromboplastin time (APTT), representative of hemorrhagic tendency, in Japanese women who received thromboprophylaxis with unfractionated subcutaneous heparin administration after cesarean section (CS). We also determined factors which affected postoperative APTT. Methods:, We studied 280 women who were administered thromboprophylaxis with unfractionated subcutaneous heparin 5000 IU two times per day after CS. Postoperative APTT under heparin was measured and the incidence of its prolongation was determined. Preoperative APTT, blood loss during surgery, postoperative hematocrit, postoperative serum total protein level, and postpartum body weight were measured, and their correlation with postoperative APTT was determined. Results:, Preoperative and postoperative APTT values were 28.3 (26.7,30.3) and 33.8 (31.0,37.5) seconds for median (interquartile range), respectively. Overall, 7.1% of patients showed ,45 s postoperative APTT. Two patients (0.7%) showed ,60 s APTT, one of whom suffered subcutaneous hemorrhage around the abdominal incision with complete healing. There were no other hemorrhagic complications. Preoperative APTT positively, and postpartum body weight inversely, correlated with postoperative APTT. The amount of blood loss, postoperative hematocrit, and postoperative serum total protein level did not correlate with postoperative APTT. No discernible deep vein thrombosis or pulmonary embolism occurred. Conclusion:, Although 7.1% of women under heparin-thromboprophylaxis showed a prolonged APTT that was 150% of the preoperative APTT, serious side effects were not observed. Subcutaneous administration of unfractionated heparin, if checking APTT prolongation 1 day after surgery, may be safe method of thromboprophylaxis after CS. [source]


Use of Electrohydraulic Lithotripsy in 28 Dogs with Bladder and Urethral Calculi

JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 6 2008
A. Defarges
Background: Electrohydraulic lithotripsy (EHL) has been used as an alternative to cystotomy in human medicine to remove urinary calculi. This prospective study evaluated the efficacy and safety of EHL to remove urinary calculi in dogs. Hypothesis: EHL is an efficient and safe method of treatment of bladder and urethral calculi in dogs. Methods: Dogs presented between January 1, 2005 and June 1, 2007 with lower urinary tract calculi diagnosed by radiographs or ultrasound examination were included in the study. Physical examination, CBC, biochemistry, urinalysis, and urine culture were performed at presentation. EHL and voiding urohydropulsion were performed under general anesthesia. Patients received IV fluids for 12 hours after which they were rechecked by ultrasound examination and discharged with antibiotics and anti-inflammatory drugs for 5 days. All patients were reevaluated 1, 3, and 6 months after presentation by physical examination, urinalysis, and ultrasonography. Results: Twenty-eight dogs (19 males, 9 females) presented with bladder or urethral calculi or both underwent lithotripsy. Their median weight was 8.3 kg. Calcium oxalate calculi were present in 22 dogs, struvite in 4, and mixed calculi in 2. Fragmentation was done in the bladder (23 dogs) and in the urethra (12 dogs). Calculus-free rate was higher for urethral than for bladder calculi in males and higher for bladder calculi in females than in males. No major complications were reported. Twelve dogs relapsed within 6 months. Conclusions: Results of this study support the use of EHL as a minimally invasive treatment for bladder calculi in females and for urethral calculi in male dogs.

Retrospective Evaluation of Partial Parenteral Nutrition in Dogs and Cats

JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 4 2002
Daniel L. Chan
The purpose of this retrospective study was to evaluate the use of partial parenteral nutrition (PPN) in dogs and cats. The medical records of all dogs and cats receiving PPN between 1994 and 1999 were reviewed to determine signalment, reasons for use of PPN, duration of PPN administration, duration of hospitalization, complications, and mortality. Complications were classified as metabolic, mechanical, or septic. One hundred twenty-seven animals (80 dogs and 47 cats) were included in the study, accounting for 443 patient days of PPN. The most common underlying diseases were pancreatitis (n = 41), gastrointestinal disease (n = 33), and hepatic disease (n = 23). Median time of hospitalization before initiation of PPN was 2.8 days (range, 0.2,10.7 days). Median duration of PPN administration was 3.0 days (range, 0.3,8.8 days). Median duration of hospitalization was 7 days (range, 2,20 days). In the 127 animals receiving PPN, 72 complications occurred. These included metabolic (n = 43), mechanical (n = 25), and septic (n = 4) complications. The most common metabolic complication was hyperglycemia (n = 19), followed by lipemia (n = 17) and hyperbilirubinemia (n = 6). Most complications were mild and did not require discontinuation of PPN. Ninety-three (73.2%) of the 127 patients were discharged. All 4 animals with septic complications were discharged from the hospital. The presence, type, and number of complications did not impact the duration of hospitalization or outcome. However, animals that received supplemental enteral nutrition survived more often than those receiving PPN exclusively. Although PPN seems to be a relatively safe method of providing nutritional support, future studies are warranted to determine its efficacy. [source]


A specific mixture of short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides induces a beneficial immunoglobulin profile in infants at high risk for allergy

ALLERGY, Issue 3 2009
E. Van Hoffen
Background:, It has been suggested that human breast milk oligosaccharides play a role in the development of the immune system in infants, and may consequently inhibit the onset of allergy. A specific prebiotic mixture of short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides (GOS/FOS) has been shown to reduce the incidence of atopic dermatitis (AD) at 6 months of age in infants at risk for allergy. Aim of the study:, This study was aimed to analyze the effect of GOS/FOS on the immune response in these infants. Methods:, In a double-blind randomized placebo-controlled study, infants received a hypoallergenic whey formula with either 8 g/l GOS/FOS in a 9 : 1 ratio (IMMUNOFORTISTM) or 8 g/l maltodextrine (placebo) for 6 months. At 3 months of age, children were vaccinated with Hexavac against a.o. diphteria, tetanus, polio (DTP). At 6 months of age, plasma samples were collected from 84 infants (verum group n = 41, placebo group n = 43). Levels of total immunoglobulins (Ig) and of cow's milk protein (CMP-) and DTP-specific Ig were measured. Results:, GOS/FOS supplementation led to a significant reduction in the plasma level of total IgE, IgG1, IgG2 and IgG3, whereas no effect on IgG4 was observed. CMP-specific IgG1 was significantly decreased. DTP-specific Ig levels were not affected. Conclusions:, This study shows that GOS/FOS supplementation induces a beneficial antibody profile. GOS/FOS reduces the total Ig response and modulates the immune response towards CMP, while leaving the response to vaccination intact. This suggests that oral GOS/FOS supplementation is a safe method to restrain the atopic march. [source]


Carbon Dioxide Laser Endoscopic Diverticulotomy Versus Open Diverticulectomy for Zenker's Diverticulum ,

THE LARYNGOSCOPE, Issue 3 2004
C. W. David Chang MD
Abstract Objectives/Hypothesis To compare open and CO2 laser,assisted endoscopic surgical management of Zenker's diverticulum. Study Design A retrospective review of 49 consecutive surgically treated patients with Zenker's diverticulum was conducted. Methods Patients' records were reviewed and analyzed for patient age and sex, size of diverticulum, incision time (time recorded from start of incision to surgical completion of case), length of hospital stay, complications, and follow-up management. A postoperative questionnaire inquiring about swallow function was conducted by mail or telephone. Swallow function was assessed on a four-point scale. Results Various procedures performed included endoscopic CO2 laser,assisted diverticulotomy (n = 24) and open diverticulectomy with cricopharyngeal myotomy (n = 28). The average incision time of laser endoscopic cases (47 min) was significantly shorter (P < .001) than that of open diverticulectomy cases (170 min). Length of hospital stay did not significantly vary between the two groups. Five patients (21%) initially treated with laser endoscopic diverticulotomy demonstrated symptomatic persistent Zenker's diverticulum; three underwent repeat operation. No open cases required repeat operation. One endoscopic case was aborted secondary to esophageal injury from placement of the endoscope. Postoperative fever was seen in two (8%) endoscopic cases and four (14%) open approach cases. No major complications (recurrent laryngeal nerve paralysis, mediastinitis, or death) were encountered. More than 90% of respondents in each treatment group reported normal or near-normal swallow function. Conclusion Laser endoscopic management is a reasonable and safe method for surgical treatment of Zenker's diverticulum in comparison with the open technique. Employment of the endoscopic approach reduces operative time and the complexity of postoperative care. Practitioners should be aware that the endoscopic approach may result in a higher failure rate.

Caecal intussusceptions in horses: a New Zealand perspective

AUSTRALIAN VETERINARY JOURNAL, Issue 7 2010
RJW Bell
Objective To establish the prevalence of intussusceptions involving the caecum in a population of horses admitted to a university hospital for colic. Design Retrospective clinical study Methods Medical records of all horses admitted to the Massey University Veterinary Teaching Hospital between 1991 and 2004 were examined for information of those horses diagnosed with an intussusception involving the caecum. Results A total of 135 horses were admitted for colic surgery during the study period and 61 horses had a diagnosis of ileocaecal (37), caecocaecal (5) or caecocolic intussusception (19) made either at surgery or necropsy. Of the horses with ileocaecal intussusception, 32 had an incomplete hand-sewn ileocaecostomy without reduction and 29 survived to discharge. All the horses with caecocaecal intussusceptions were diagnosed preoperatively via rectal examination and/or transabdominal ultrasound: 2 were euthanased at surgery and 3 survived to discharge. In the 19 horses with caecocolic intussusceptions, manually reduction at surgery was performed in 6 and 5 of them survived to discharge. A typhlectomy was performed via a colotomy in 6 horses, 3 of which survived to discharge. Conclusions The high prevalence of intussusceptions involving the caecum seen at this referral centre may indicate a higher prevalence in New Zealand than is reported elsewhere in the world. Clinical relevance Intussusceptions involving the caecum should be considered as a differential diagnosis in horses presenting with chronic low-grade colic. Transabdominal ultrasound is useful for identifying caecocaecal and caecocolic intussusceptions. Hand-sewn side-to-side incomplete ileocaecostomy is a quick, effective and safe method of surgical treatment of ileocaecal intussusceptions. [source]


Rectal analgesia for the relief of perineal pain after childbirth: a randomised controlled trial of diclofenac suppositories

BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 10 2004
Jodie M. Dodd
Objective To evaluate rectal diclofenac in the relief of perineal pain after trauma during childbirth. Design A randomised, double-blind trial. Setting Delivery Suite, Women's and Children's Hospital, South Australia. Population Women with a second-degree (or greater) perineal tear or episiotomy. Methods Women were randomly allocated to either diclofenac or placebo suppositories (Anusol), using a computer-generated randomisation schedule with stratification for parity and mode of birth. Treatment packs contained two × 100 mg diclofenac or two placebo suppositories, the first being inserted when suturing was complete, and the second 12,24 hours after birth. Women were asked to complete questionnaires at 24 and 48 hours after birth relating to their degree of perineal pain using the validated Short Form McGill Pain Questionnaire. Main outcome measures Pain scores at 24 and 48 hours after birth. Results A total of 133 women were recruited, with 67 randomised to diclofenac suppositories and 66 to placebo. Women in the diclofenac group were significantly less likely to experience pain at 24 hours while walking (RR 0.8; 95% CI 0.6 to 1.0), sitting (RR 0.8; 95% CI 0.6 to 1.0), passing urine (RR 0.6; 95% CI 0.4 to 1.0) and on opening their bowels (RR 0.6; 95% CI 0.2 to 0.9) compared with those women who received placebo. These differences were not sustained 48 hours after birth. Conclusions The use of rectal non-steroidal anti-inflammatory drug suppositories is a simple, effective and safe method of reducing the pain experienced by women following perineal trauma within the first 24 hours after childbirth.

Initial clinical experience with distal protection using the FilterWire in patients undergoing coronary artery and saphenous vein graft percutaneous intervention

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 2 2002
Jeffrey J. Popma MD
Abstract Percutaneous coronary intervention (PCI) of saphenous vein grafts (SVG) and native coronary arteries may be associated with embolization of particulate debris into the distal microcirculation. The FilterWire uses a polyurethane filter bag contained on a radiopaque loop to trap embolic debris during native vessel and SVG intervention. The objectives of this study were to assess the feasibility and safety of the FilterWire during PCI and to examine the size and content of the particulate debris captured during SVG and native vessel intervention. Early angiographic, in-hospital, and 30-day clinical outcomes were reviewed in 35 patients with 36 lesions treated with the FilterWire during PCI. Lesions were located in 22 (61%) native coronary arteries and in 14 (39%) SVGs. Multivessel coronary artery disease was present in 75% of patients. Lesions were complex (ACC/AHA complexity B2 or C) in 81% of cases. The FilterWire was successfully delivered and deployed distal to the site of coronary intervention in 92% of lesions, including 95% of native vessels and 82% of SVG lesions. Embolic debris was entrapped in 82% of these cases. The average particulate debris had a mean major axis of 490 ,m (range, 45,3,302 ,m) and minor axis of 226 ,m (range, 33,1,677 ,m). Although reduced flow was common (36.1%) when the FilterWire was in place, there were no sustained episodes of abrupt closure and only one (2.8%) patient developed sustained no-reflow after FilterWire removal. Distal branch vessel embolization was found in four (11.1%) cases. Major adverse cardiac events occurred in 5 (14%) of 35 patients treated with the device, although 2 of these patients were evolving an acute myocardial infarction at the time of the procedure; in patients meeting the prospectively defined inclusion criteria, the major adverse cardiac event was 6%. These results suggest that the FilterWire is a feasible and safe method of collecting particulate debris released during SVG and native vessel coronary intervention. Its benefit over conventional therapy and other distal protection devices is currently under study. Cathet Cardiovasc Intervent 2002;57:125,134. © 2002 Wiley-Liss, Inc. [source]


Longterm follow-up of diode laser transscleral cyclophotocoagulation in the treatment of refractory glaucoma

ACTA OPHTHALMOLOGICA, Issue 1 2010
Paolo Frezzotti
Abstract. Purpose:, This prospective study was conducted to evaluate the efficacy and safety of transscleral diode laser cyclophotocoagulation (TDLCP) in advanced refractory glaucoma. Methods:, A total of 124 eyes in 121 patients with advanced glaucoma refractory to medical treatment were treated consecutively with TDLCP. Success was defined as final intraocular pressure (IOP) of 5,21 mmHg in eyes with visual acuity (VA) of more than hand movements (HM) and relief of pain in eyes with VA of HM or less, including blind eyes. Results:, Mean patient age was 65.6 ± 17.1 years (range 14,91 years). Mean follow-up was 17 ± 14.6 months (range 3,42 months). Mean pretreatment IOP was 29.9 ± 8.4 mmHg (range 17,58 mmHg) and IOP at last follow-up was 20.8 ± 8 mmHg (range 6,45 mmHg) (p < 0.001). The number of laser applications (mean 9.2 ± 2.8, range 4,15) and maximal laser power (mean 2.01 ± 0.22 mW, range 1.3,3.0 mW) were not associated with lower postoperative IOP. Intraocular pressure of , 21 mmHg was recorded in 63.0% of eyes at the last follow-up visit. Overall, 28 (21.7%) eyes required at least one retreatment. No phthisis bulbi or persistent hypotonia developed. Conclusions:, TDLCP is an effective and safe method for the treatment of advanced refractory glaucoma, although repeated treatments are often necessary. [source]


Thiopental pharmacokinetics in newborn infants: a case report of overdose

ACTA PAEDIATRICA, Issue 10 2009
Elisabeth Norman
Abstract Thiopental may be used for sedation before intubation in newborn infants. A boy, born at 33 weeks of gestation (gw); birth weight 2435 g, was prescribed thiopental 3 mg/kg before intubation. He developed temporary hypotension and oxygen desaturation, and remained unconscious for longer than expected with a suppressed electroencephalography for 48 h. Serum thiopental concentration was 82, 59, 42 and 32 ,mol/L after 20 min and 6, 24 and 68 h respectively. Serum concentrations from five newborn infants at the same time points after intubation with the same thiopental dose were used as reference values, and indicated a 10-fold overdose in the index case. The cause of the overdose could not be identified. The infant recovered; cerebral magnetic resonance imaging at the age of 42 gw and psychomotor development at 2 years were normal. These results show that thiopental concentrations are variable in neonates and there is a high risk of dosage error as no specific paediatric formulation is available. Conclusion:, Well-designed procedures and continuous education are required to prevent errors and adverse events during drug delivery to newborn infants. To develop a safe method of administration for thiopental, an extended pharmacokinetic and pharmacodynamic study in neonates is warranted. [source]


Oral glucose as an analgesic to reduce infant distress following immunization at the age of 3, 5 and 12 months

ACTA PAEDIATRICA, Issue 2 2007
Margit Thyr
Abstract Aim: To evaluate oral glucose as an analgesic to reduce infant distress after immunization during the first year of life and to investigate if these effects change during this period. Methods: A prospective controlled trial of the effectiveness of glucose on crying response to immunizations at 3, 5 and 12 months of age. A total of 110 infants were randomized to receive 2 mL of 30% glucose or water. The same solution was given at 3, 5 and 12 months. Crying was registered from onset of the injection up to 120 seconds. Infanrix Polio Hib was administered intra-muscular in the thigh. Observation nurse and parents were blind to the nature of the solution. Results: Administration of glucose reduced the mean crying time by 22% at 3 months, 62% at 5 months and 52% at 12 months. The difference was significant at 5 and at 12 months. In the water group, there was a significant correlation between the children who cried at 3 months and who subsequently cried at 5 and 12 months. No correlations were found in the glucose group. Conclusion: Sweet solution can be used as a simple and safe method to reduce the distress following immunization in infants up to 12 months. [source]


Tap-water enema for children with myelomeningocele and neurogenic bowel dysfunction

Abstract Aim: To evaluate the outcome of transrectal irrigation (TRI) using clean tap water without salt in children with myelomeningocele and neurogenic bowel problems. Methods: 40 children (21 boys and 19 girls; aged 10 mo to 11 y) with myelomeningocele and neurogenic bowel dysfunction were treated with TRI given by a stoma cone irrigation set daily or every second day. A questionnaire on the effects on faecal incontinence, constipation and self-management was completed by the parents, 4 mo,8 y (median 1.5 y) after start. Effects on rectal volume, anal sphincter pressure and plasma sodium were evaluated before and after the start of irrigation. Results: At follow-up, 35 children remained on TRI, four had received appendicostomy, while one defecated normally. For all children but five (35/40; 85%) the procedure worked satisfactorily, but a majority found the procedure very time consuming and only one child was able to perform it independently. All children were free of constipation; most (35/40) were also anal continent. Rectal volume and anal sphincter pressure improved, while plasma sodium values remained within the normal range. Conclusion: Transrectal irrigation with tap water is a safe method to resolve constipation and faecal incontinence in children with myelomeningocele and neurogenic bowel dysfunction, but it does not help children to independence at the toilet.

scaramuzzi n., walsh r.m., brennan p. &walsh m. (2001) Clin. Otolaryngol.26, 307,309 Treatment of intractable epistaxis using arterial embolization Arterial embolization has become the procedure of choice for managing intractable epistaxis in certain centres in North America and Europe, with arterial ligation reserved for those patients in which it fails. In Ireland, the role of this relatively new technique is poorly defined. The aim of this retrospective study was to investigate the outcome of all patients who underwent arterial embolization for intractable epistaxis in Dublin since it was introduced in 1998. Embolization resulted in complete and immediate resolution of epistaxis in 10 out of 12 patients (82%). Two patients required carotid ligation because of persistent epistaxis. One other patient had a further minor epistaxis 2 days following embolization, which was treated successfully with cautery. No major complications occurred in any of the patients. This study suggests that arterial embolization is an effective and safe method of managing patients with intractable epistaxis. [source]


Feasibility of sputum induction in lung transplant recipients

Abstract:, Sputum induction (SI) is nowadays being applied as a non-invasive and safe method to investigate airway inflammation in pulmonary diseases. We investigated the feasibility of SI after lung transplantation (LTX), and compared sputum and bronchoalveolar lavage (BAL) cellular characteristics and interleukin-8 (IL-8) levels. Results were also compared with 11 healthy subjects. SI as performed between 26 and 1947 d after LTX in 19 recipients, was successful in 16 of 22 attempts (73%). Six patients failed to produce sputum after induction, mostly just post-LTX and with having a lower forced expiratory volume in 1 s (FEV1). The success rate in clinically stable patients after the first month post-LTX was 93%. Side-effects were absent. Sputum recovery, viability and squamous cell contamination were comparable between LTX patients and healthy subjects. In the LTX group, total cell counts, neutrophil percentages and IL-8 levels were much higher in SI than BAL (1.6 × 106/mL, 65.5% and 54.2 ng/mL vs. 0.1 × 106/mL, 3.0% and 0.01 ng/mL; p < 0.001). Although LTX-neutrophil percentages in SI and BAL correlated properly (, = 0.72, p = 0.04), both techniques are not interchangeable. We conclude that sputum induction is feasible, well tolerated, and without major side-effects in stable patients after the first month post-LTX. Induced sputum may be a useful tool to study inflammatory changes of the airways after LTX, and because of the large quantity of neutrophils sampled, especially for further studies on the pathogenesis of bronchiolitis obliterans.

Virtual colonoscopy vs conventional colonoscopy in patients at high risk of colorectal cancer , a prospective trial of 150 patients

COLORECTAL DISEASE, Issue 2 2009
T. J. White
Abstract Objective, Virtual colonoscopy (VC)/CT colonography has advantages over the well-documented limitations of colonoscopy/barium enema. This prospective blinded investigative comparison trial aimed to evaluate the ability of VC to assess the large bowel, compared to conventional colonoscopy (CC), in patients at high risk of colorectal cancer (CRC). Method, We studied 150 patients (73 males, mean age 60.9 years) at high risk of CRC. Following bowel preparation, VC was undertaken using colonic insufflation and 2D-spiral CT acquisition. Two radiologists reported the images and a consensual agreement reached. Direct comparison was made with CC (performed later the same day). Interobserver agreement was calculated using the Kappa method. Postal questionnaires sought patient preference. Results, Virtual colonoscopy visualized the caecum in all cases. Five (3.33%) VCs were classified as inadequate owing to poor distension/faecal residue. CC completion rate was 86%. Ultimately, 44 patients had normal findings, 44 had diverticular disease, 11 had inflammatory bowel disease, 18 had cancers, and 33 patients had 42 polyps. VC identified 19 cancers , a sensitivity and specificity of 100% and 99.2% respectively. For detecting polyps > 10 mm, VC had a sensitivity and specificity (per patient) of 91% and 99.2% respectively. VC identified four polyps proximal to stenosing carcinomas and extracolonic malignancies in nine patients (6%). No procedural complications occurred with either investigation. A Kappa score achieved for interobserver agreement was 0.777. Conclusion, Virtual colonoscopy is an effective and safe method for evaluating the bowel and was the investigation of choice amongst patients surveyed. VC provided information additional to CC on both proximal and extracolonic pathology. VC may become the diagnostic procedure of choice for symptomatic patients at high risk of CRC, with CC being reserved for therapeutic intervention, or where a tissue diagnosis is required. [source]
