Large-volume paracentesis (LVP) can be time and labor intensive depending on the amount of ascites removed and the method of drainage. Wall suction has been adopted as the preferred method of drainage at many centers, though the safety and benefits of this technique have not been formally evaluated. The primary objective of this study was to define the cost and time savings of wall suction over the traditional glass vacuum bottle method for ascites drainage. The secondary objective was to compare the safety profile and patient satisfaction using these two techniques. We conducted a randomized, controlled pilot study of the wall suction versus vacuum bottle methods for LVP in hospitalized patients. All LVPs were performed under ultrasound guidance by a single proceduralist. Patients with at least 4 liters removed received 25% intravenous albumin, 8 g/liter fluid removed. Demographic, clinical characteristics, and procedure details were recorded. Laboratory and hemodynamic data were recorded for 24 h prior to and 24-48 h post LVP. An electronic chart review was conducted to evaluate procedure-related complications. Data were compared using Fisher's exact test, t test, or Mann-Whitney U test. Thirty-four patients were randomized to wall suction at 200 mmHg (n = 17) or glass vacuum bottle drainage (n = 17). Wall suction was significantly faster and less costly than vacuum bottle drainage (7 versus 15 min, p = 0.002; $4.59 versus $12.73, p < 0.001). There were no differences in outcomes at 24 and 48 h post LVP, or at 60-day follow up. Performing LVP using wall suction resulted in significantly shorter procedure time and supply cost savings. There were no differences in outcomes between the groups, suggesting equivalent safety, though larger studies powered to detect small differences are needed. Given its efficiency, convenience, and cost effectiveness, wall suction may be a superior method of ascites drainage for LVP.

Aims Although we previously demonstrated abdominal paracentesis drainage (APD) preceding percutaneous catheter drainage (PCD) as the central step for treating patients with moderately severe (MSAP) or severe acute pancreatitis (SAP), the predictors leading to PCD after APD have not been studied. Methods Consecutive patients with MSAP or SAP were recruited between June 2011 and June 2013. As a step-up approach, all patients initially received medical management, later underwent ultrasound-guided APD before PCD, if necessary, followed by endoscopic necrosectomy through the path formed by PCD. APD primarily targeted fluid in the abdominal or pelvic cavities, whereas PCD aimed at (peri)pancreatic fluid. Results Of the 92 enrolled patients, 40 were managed with APD alone and 52 received PCD after APD (14 required necrosectomy after initial PCD). The overall mortality was 6.5%. Univariate analysis showed that among the 20 selected parameters, 13 factors significantly affected PCD intervention after APD. Multivariate analysis revealed that infected (peri)pancreatic collections (P = -0.001), maximum extent of necrosis of more than 30% of the pancreas (P = -0.024), size of the largest necrotic peri(pancreatic) collection (P = -0.007), and reduction of (peri)pancreatic fluid collections by <50% after APD (P = -0.008) were all independent predictors of PCD. Conclusions Infected (peri)pancreatic collections, a largest necrotic peri(pancreatic) collection of more than 100 ml, and reduction of (peri)pancreatic fluid collections by <50% after APD could effectively predict the need for PCD in the early course of the disease.

Introduction Appropriate mechanical ventilation and prevention of alveolar collaps is mainly dependent on transpulmonary pressure TPP. TPP is assessed by measurement of esophageal pressure EP, largely influenced by pleural and intraabdominal pressure IAP. Consecutively, TPP-guided ventilation might be particularly useful in patients with high IAP. This study investigates the impact of large volume paracentesis LVP on TPP, EP, IAP as well as on hemodynamic and respiratory function in patients with liver cirrhosis and tense ascites. Material and methods We analysed 23 LVP-procedures in 11 cirrhotic patients ventilated with the AVEA Viasys respirator (CareFusion, USA) which is capable to measure EP via an esophageal tube. Results LVP of a mean volume of 4826±1276 mL of ascites resulted in marked increases in inspiratory (17.9±8.9 vs. 5.4±13.3 cmH2O; p<0.001) as well as expiratory TPP (-3.0±4.7 vs. -15.9±10.9 cmH2O; p<0.001; primary endpoint). In parallel, the inspiratory (2.4±8.7 vs. 14.1±14.5 cmH2O; p<0.001) and expiratory EP (12.4±6.0 vs. 24.9±11.3 cmH2O; p<0.001) significantly decreased. The effects were most pronounced for the release of the first 500 mL of ascites. LVP evoked substantial decreases in IAP and central venous pressure CVP. By contrast, mean arterial pressure, cardiac index, global end-diastolic volume index, extravascular lung water index and systemic vascular resistance index did not change. Among the respiratory parameters we observed an increase in paO2/FiO2 (247.7±60.9 vs. 208.3±46.8 mmHg; p<0.001) and a decrease in Oxygenation Index OI (4.8±2.0 vs. 5.8±3.1 cmH2O/mmHg; p = 0.002). Tidal volume (510±100 vs. 452±113 mL; p = 0.008) and dynamic respiratory system compliance Cdyn (46.8±15.9 vs. 35.1±14.6 mL/cmH20; p<0.001) increased, whereas paCO2 (47.3±10.7 vs. 51.2±12.3mmHg; p = 0.046) and the respiratory rate decreased (17.1±7.3 vs. 19.6±7.8 min-1; p = 0.010).

Congenital chylous ascites in the neonatal period is a rare entity. Total parenteral nutrition (TPN), medium chain triglyceride (MCT)-based diet, octreotide and repeated paracentesis are regarded as appropriate medical treatment for congenital chylous ascites, and surgery is recommended when conservative therapy has failed. We present two cases in which ascites were confirmed via an abdominal sonogram and diagnostic paracentesis. In our clinical experience, rice soup combined with PN can be a safe and effective intervention.

Ascites is a common complication of advanced cancer and frequently requires paracentesis to reduce symptoms of pain, anorexia, and dyspnea. For many patients repeat paracenteses are required at short intervals. We prospectively studied 15 patients with recurrent ascites of malignancy to determine if intraperitoneal triamcinolone hexacetonide, a slowly metabolized corticosteroid, produced objective and symptomatic responses. After biochemical, radiological, and symptom assessment and the establishment of the interval between paracenteses, patients underwent large-volume paracentesis followed by intraperitoneal triamcinolone hexacetonide 10 mg/kg. Patients were followed after treatment for assessment of symptoms and physical signs of ascites. Repeat paracentesis was performed when symptomatic ascites recurred. Symptomatic ascites recurred in 13 of 15 patients, but the interval between paracenteses was extended from 9.5 +/- 1.6 days to 17.5 days (P = 0.0086). Symptom questionnaire scores assessing well-being, nausea, abdominal pain, dyspnea, appetite, appearance, and change in abdominal size on a scale from 0 to 6 averaged 3.2 +/- 0.3 at entry and 2.5 +/- 0.2 at the 2-week assessment (P = 0.026). Self-assessed symptoms, feeling of well-being, abdominal distention, and physical appearance improved significantly. The mean serum cortisol decreased from baseline, suggesting that some systemic corticosteroid absorption occurred. Thirteen of 15 patients have died, with a median survival of 42 days. Potential adverse effects included 1 episode each of transient abdominal pain, bacterial peritonitis, and localized herpes zoster infection. In patients with ascites of malignancy, intraperitoneal triamcinolone hexacetonide appears to postpone the requirement for repeat paracentesis and improve symptoms of malignant ascites.

Traditionally, stab wounds violating the abdominal wall fascia led to exploratory celiotomy that was often nontherapeutic. In an attempt to limit the number of nontherapeutic celiotomies (NTC), we devised a protocol to prospectively study stab wounds violating the anterior abdominal wall fascia. Through protocol, abdominal stab wounds were explored in stable adults. If the anterior fascia was violated, paracentesis and, if necessary, peritoneal lavage was undertaken in the absence of previous abdominal surgery. If evisceration was noted, it was reduced and the patient lavaged. Fascial penetration was noted in 72 patients. 46 patients underwent celiotomy: because of shock/peritonitis in 8 (2 NTC), fascial penetration with a history of previous celiotomy in 7 (5 NTC), positive paracentesis in 20 (5 NTC), or positive lavage in 10 (4 NTC). One patient underwent late celiotomy without ill-effect after a negative lavage because she subsequently developed fever and localized peritonitis (ice pick injury to cecum). Eleven patients had evisceration; nine underwent celiotomy. Patients with abdominal stab wounds can be selectively managed safely. More than one-third with fascial penetration, some with evisceration, avoided exploration. Only one patient underwent delayed celiotomy and did so without detriment. Nontherapeutic celiotomy rates were highest in patients with previous abdominal surgery who, thereby, could not undergo paracentesis/lavage; excluding these patients, the nontherapeutic celiotomy rate was 17% (11/65) for those with fascial penetration.

Information on antibiotic concentrations in the equine eye following systemic therapy is limited. Reports that Leptospira spp. are frequently present in the eyes of horses with recurrent uveitis, emphasises a need for studies on ocular concentrations of specific antibiotics. 1) Enrofloxacin, administered i.v. at 7.5 mg/kg bwt q. 24 h, results in aqueous humour concentrations greater than the reported minimum inhibitory concentration (MIC) for Leptospira pomona. 2) Aqueous humour paracentesis sufficiently disrupts the blood-aqueous humour barrier (BAB) to cause an increase in aqueous humour protein and enrofloxacin concentrations. Aqueous humour enrofloxacin and total protein concentrations were determined in 6 healthy, mature horses after i.v. administration of enrofloxacin. Paracentesis was performed on the left eye on Days 3 and 4, 1 h following enrofloxacin administration, to determine enrofloxacin concentrations in healthy eyes and in eyes with mechanical disruption of the BAB. Paracentesis was also performed on the right eye 23 h after enrofloxacin administration. Blood samples were collected from the horses at identical times to determine enrofloxacin aqueous humour:plasma ratios. Mean +/- s.d. enrofloxacin concentration in the aqueous humour 1 h post administration on Day 3 was 0.32 +/- 0.10 mg/l (range 0.18-0.47); and aqueous humour enrofloxacin, total protein and aqueous humour:plasma enrofloxacin ratios were higher on Day 4 than Day 3. Following disruption of the BAB, enrofloxacin concentrations were above the reported MIC for Leptospira pomona.

Reversal of retinal and optic disc ischemia in a patient with sickle cell trait and glaucoma secondary to traumatic hyphema.

A 14-year-old black boy with sickle cell trait, who sustained a traumatic hyphema, developed moderately elevated intraocular pressure that failed to respond to carbonic anhydrase inhibitors and osmotic agents. On the tenth postinjury day, a sudden increased cupping of the optic disc and partial central retinal artery obstruction caused painless loss of vision. Reversal of the cupping, the retinal ischemia, and the intraocular pressure was documented following anterior chamber paracentesis, and visual acuity returned to 6/6. Pathophysiology of the posterior ischemia is discussed. This case documents the potentially debilitating course of traumatic hyphema in "benign" sickle cell trait and its avoidance with proper management. The authors endorse recent suggestions for careful observation of any sickle cell patient with traumatic hyphema, and recommend anterior chamber paracentesis, supplemental oxygen, and avoidance of osmotic agents, if secondary glaucoma develops following the initial trauma.

Previous research has demonstrated that physician clinical suspicion, determined without assessing fluid appearance, is not adequate to rule out spontaneous bacterial peritonitis (SBP) without fluid testing. To determine the sensitivity of physician clinical suspicion, including a bedside assessment of fluid appearance, in the detection of SBP in Emergency Department (ED) patients undergoing paracentesis. We conducted a prospective, observational study of ED patients with ascites undergoing paracentesis at three academic facilities. The enrolling physician recorded the clinical suspicion of SBP ("none," "low," "moderate," or "high"), and ascites appearance ("clear," "hazy," "cloudy," or "bloody"). SBP was defined as an absolute neutrophil count ≥ 250 cells/mm(3), or culture pathogen growth. We defined "clear" ascites fluid as negative for SBP, and "hazy," "cloudy," or "bloody" as positive. A physician clinical suspicion of "none" or "low" was considered negative for SBP, and an assessment of "moderate" or "high" was considered positive. The primary outcome measure was sensitivity of physician clinical impression and ascites appearance for SBP. There were 348 cases enrolled, with SBP diagnosed in 43 (12%). Physician clinical suspicion had a sensitivity of 42% (95% confidence interval [CI] 29-55%) for the detection of SBP. Fluid appearance had a sensitivity of 72% (95% CI 58-83%). Physician clinical impression, which included an assessment of fluid appearance, had poor sensitivity for the detection of SBP and cannot be used to exclude the diagnosis. Routine laboratory fluid analysis is indicated after ED paracentesis, even in patients considered to have a low degree of suspicion for SBP. Copyright © 2013 Elsevier Inc. All rights reserved.

Viscoelastic Tamponade Applied to the Ocular Surface for Enhanced Control of Gaseous Egress From the Anterior Chamber During Final Bubble Titration in DMEK Surgery: The "Polite" Burp.

PubMed

Sales, Christopher S; Fernandez, Ana Alzaga; Anwar, Zane

2018-07-01

To present a novel technique for enhancing the surgeon's control over the volume of air or gas that is "burped" from the anterior chamber during final bubble and intraocular pressure (IOP) titration in Descemet membrane endothelial keratoplasty. After ascertaining that the intracameral bubble is either too large and/or has rendered IOP too high, a bead of ophthalmic viscoelastic is applied to the ocular surface over a paracentesis incision, which is then depressed in the usual fashion to burp gas from the anterior chamber. The weight and viscosity of the viscoelastic create a tamponade that slows the egress of gas from the anterior chamber, thereby making it more controllable. If the bubble size or IOP needs to be reduced at the conclusion of the Descemet membrane endothelial keratoplasty procedure, application of ophthalmic viscoelastic over the paracentesis can enhance the surgeon's control over the volume of gas burped from the anterior chamber, thereby reducing the tendency to swing between a bubble that is too large or too small.

In this study, we examined a novel variant of 'big-bubble' deep anterior lamellar keratoplasty using trypan-blue-stained viscoelastic device for the creation of a pre-descemetic bubble. Ten corneoscleral rims were mounted on an artificial anterior chamber (AC). The AC was filled with air through a limbal paracentesis. A Melles' triangulated spatula was inserted through the paracentesis, with its tip penetrating the AC, was then slightly retracted and pushed into the deep stroma above the roof of the paracentesis. A mixture of trypan blue and viscoelastic device (Healon, Abbott Medical Optics, Abbott Park, Illinois) was injected into this intra-stromal pocket using a 27-G cannula to create a pre-descemetic separation bubble. Bubble type and visualization of dyed viscoelastic device were noted. The method was later employed in three cases. In all 10 corneoscleral rims, the technique successfully created a visible pre-descemetic (type 1) bubble that could be expanded up to the predicted diameter of trephination. Subsequent trephination and the removal of corneal stroma were uneventful. In two out of four clinical cases, a type 1 bubble was created, while in two others, visco-dissection failed and dyed viscoelastic was seen in the AC. The presented technique holds promise of being a relatively easy to perform, predictable and well-controlled alternative for achieving a type 1 bubble during deep anterior lamellar keratoplasty surgery. The trypan-blue-stained viscoelastic device facilitates proper visualization and control of the separation bubble and assists in identifying the penetrance to the separation bubble prior to removal of the stromal cap. © 2017 Royal Australian and New Zealand College of Ophthalmologists.

Many instructional materials for point-of-care ultrasound (US)-guided procedures exist; however, their quality is unknown. This study assessed widely available educational videos for point-of-care US-guided procedures relevant to internal medicine: central venous catheterization, thoracentesis, and paracentesis. We searched Ovid MEDLINE, YouTube, and Google to identify videos for point-of-care US-guided paracentesis, thoracentesis, and central venous catheterization. Videos were evaluated with a 5-point scale assessing the global educational value and a checklist based on consensus guidelines for competencies in point-of-care US-guided procedures. For point-of-care US-guided central venous catheterization, 12 videos were found, with an average global educational value score ± SD of 4.5 ± 0.7. Indications to abort the procedure were discussed in only 3 videos. Five videos described the indications and contraindications for performing central venous catheterization. For point-of-care US-guided thoracentesis, 8 videos were identified, with an average global educational value score of 4.0 ± 0.9. Only one video discussed indications to abort the procedure, and 3 videos discussed sterile technique. For point-of-care US-guided paracentesis, 7 videos were included, with an average global educational value score of 4.1 ± 0.9. Only 1 video discussed indications to abort the procedure, and 2 described the location of the inferior epigastric artery. The 27 videos reviewed contained good-quality general instruction. However, we noted a lack of safety-related information in most of the available videos. Further development of resources is required to teach internal medicine trainees skills that focus on the safety of point-of-care US guidance. © 2017 by the American Institute of Ultrasound in Medicine.

To compare the efficacy of mapracorat (formerly ZK-245186, and subsequently BOL-303242-X), a novel selective glucocorticoid receptor agonist (SEGRA), with that of dexamethasone (DEX) in rabbit models of ocular disease. The effects of topical BOL-303242-X and DEX on intraocular pressure (IOP) and body weight changes were also evaluated. Dry eye was induced by atropine sulfate administration and was treated with saline, BOL-303242-X (0.1%-1.0%), DEX (0.1%), Restasis 0.05% (Allergan, Inc., Irvine, CA), or Refresh Endura (Allergan, Inc.) three times per day for 7 to 8 days. For paracentesis studies, vehicle, BOL-303242-X (0.1%, 0.5%, and 1.0%), or DEX (0.1%) were repeatedly administered topically 3 hours before paracentesis and continued for 90 minutes afterward. For IOP and body weight measurements, right eyes of rabbits were topically treated with vehicle, BOL-303242-X (1.0% or 0.1%), or DEX (0.1%) four times per day for 6 weeks. In the dry eye model, BOL-303242-X and DEX were fully efficacious, maintaining tear volume and tear breakup time (TBUT) at baseline levels. Although Restasis improved tear volume compared with vehicle, no changes were observed in TBUT. In the paracentesis study, BOL-303242-X and DEX improved ocular inflammation. BOL-303242-X reduced protein and PGE(2) levels. Finally, BOL-303242-X showed no effects on integrated IOP or body weight, whereas DEX significantly increased integrated IOP and prevented the increase of body weight observed in the vehicle-treated animals. BOL-303242-X shows full anti-inflammatory efficacy (similar to DEX) in experimental models of dry eye and postoperative inflammation while demonstrating reduced effects in IOP and body weight. These data indicate that mapracorat, a SEGRA, shows efficacy similar to that of traditional steroids while exhibiting an improved side effect profile in IOP and muscle wasting.

The use of human albumin is common in hepatology since international scientific societies support its administration to treat or prevent severe complications of cirrhosis, such as the prevention of post-paracentesis circulatory dysfunction after large-volume paracentesis and renal failure induced by spontaneous bacterial peritonitis, and the treatment of hepatorenal syndrome in association with vasoconstrictors. However, these indications are often disregarded, mainly because the high cost of human albumin leads health authorities and hospital administrations to restrict its use. On the other hand, physicians often prescribe human albumin in patients with advanced cirrhosis for indications that are not supported by solid scientific evidence and/or are still under investigation in clinical trials.In order to implement appropriate prescription of human albumin and to avoid its futile use, the Italian Association for the Study of the Liver (AISF) and the Italian Society of Transfusion Medicine and Immunohaematology (SIMTI) nominated a panel of experts, who reviewed the available clinical literature and produced practical clinical recommendations for the use of human albumin in patients with cirrhosis.

Nowadays, the patients with deep brain stimulation (DBS) devices are restricted to undertake 1.5T magnetic resonance imaging (MRI) according to the guideline. Nevertheless, we conducted an experiment to test pathological change near the leads in different field-strength MRI. Twenty-four male New Zealand rabbits were assigned to Group 1 (G1, n = 6, 7.0T, DBS), Group 2 (G2, n = 6, 3.0T, DBS), Group 3 (G3, n = 6, 1.5T, DBS), and Group 4 (G4, n = 6, 1.5T, paracentesis). DBS leads were implanted in G1, G2 and G3, targeting left nucleus ventralis posterior thalami. Paracentesis was performed in G4. 24 h after MRI scan, all animals were killed for examining pathological alternation (at different distance from lead) via transmission electron microscopy. Our results suggest that the severity of tissue injury correlates with the distance to electrode instead of field strength of MRI. Up to now, the reason for the restriction of MRI indicated no significantly different pathological change.

To compare the incidence of spontaneous bacterial peritonitis in cirrhotic outpatients and inpatients undergoing therapeutic paracentesis From January 1 to May 31, 2004, 1041 patients from 70 different hospitals underwent 2123 therapeutic abdominal paracentesis (AP) performed as a outpatient procedure in 355 and as inpatient procedure in 686 cases respectively. The following parameters were compared prospectively between outpatients and inpatients: spontaneous bacterial peritonitis (SBP) prevalence, age, gender, cause of cirrhosis, symptoms, score and grade according to Child-Pugh classification, cirrhosis complications, antibiotics treatment, serum creatinine, platelet count and ascitic protein concentration. SBP was observed in 91 patients. In the whole population the SBP prevalence was 8.7% (95%CI: 7.2-10.6) it was 11.7% (95%CI: 9.5-14.3) in inpatients and 3.1% (95%CI: 1.7-5.5) in outpatients (P < 0.00001). SBP prevalence was 8.3% (95%CI: 4.3-15.6) in symptomatic outpatients vs 1.2% (95%CI: 0.4-3.4) in asymptomatic outpatients (P < 0.002). Patients undergoing outpatient AP were significantly different from those undergoing inpatient AP; they were older (61.1 ± 11.1 years vs 59.4 ± 11.7 years; P = 0.028), cause of cirrhosis was less often alcohol (83 .7 vs 88.2%; P < 0.001), Child-Pugh score was lower (8.9 vs 10.1; P < 0.001) and more often B than C (63.7% vs 38%; P < 0.001). In addition, in outpatients the platelet count was higher (161 ± 93 Giga/L vs 143 ± 89 Giga/L; P = 0.003), serum total bilirubin concentration was lower (38.2 ± 60.7 μmol/L vs 96.3 ± 143.3 μmol/L; P < 0.0001), and ascitic protein concentration higher (17.9 ± 10.7 g/L vs 14.5 ± 10.9 g/L; P < 0.001) than in inpatients. In asymptomatic cirrhotic outpatients, the incidence of spontaneous bacterial peritonitis is low thus exploratory paracentesis could be avoided in these patients without significant risk.

Design of a novel system for spectroscopy measurements of the aqueous humor

The authors report on the design of a system which will enable real time measurements of (therapeutic) drug concentrations in the anterior chamber of the eye. Currently the concentration of therapeutic drugs in the anterior chamber is determined by analyzing samples which have been removed from the aqueous humor of laboratory animal eyes. This sampling via paracentesis can be painful and does not provide a continuous measurement. Our system will be far less invasive, removing the need for sampling via paracentesis, and also providing a continuous measurement, enabling a more complete understanding of the kinetics of ophthalmic drugs. A key component in our novel system is a specially constructed contact lens. We report on the design, optimization and manufacture of such a contact lens system capable of directing UV/VIS light in, across and out of the anterior chamber of the eye, thereby enabling absorption spectroscopy measurements of the aqueous humor to be undertaken. Design of the one piece contact lens/mirror system was achieved using the Zemax optical design software package and the lens was fabricated from synthetic fused silica. Results from modeling of the lens and experimental measurements on light propagation across the anterior chamber of animal eyes assisted by the lens will be reported.

A young female presented with an acute abdominal pain and oliguria for 1 week following normal vaginal delivery. No history of hematuria was present. Patient was having lochia rubra. Sealed uterine rupture was suspected clinically. Initial ultrasound of the patient showed distended urinary bladder containing Foley catheter ballon with clamping of Foley catheter and particulate ascites. Abdominal paracentesis revealed hemorrhagic fluid. Contrast-enhanced computed tomography of abdomen revealed ascites, distended urinary bladder and no extraluminal contrast extravasation in delayed scan. As patient condition deteriorated, repeat ultrasound guided abdominal paracentesis was done which revealed transudative peritoneal collection with distended bladder. Cystoscopy revealed urinary bladder ruptures with exudate sealing the rupture site. Exploratory laparotomy was done and a diagnosis of extraperitoneal bladder rupture was confirmed. The rent was repaired in layers. She was put on continuous bladder drainage for 3 weeks followed by bladder training. It presented in a unique way as there was hemorrhagic peritoneal tap, no macroscopic hematuria and urinary bladder was distended in spite of urinary bladder wall rupture which delayed the diagnosis and treatment. Complete emptying of urinary bladder before second stage of labor and during postpartum period with perineal repair is mandatory to prevent urinary bladder rupture. PMID:26985426

The uveitis masquerade syndromes (UMS) are a group of ocular diseases that may mimic chronic intraocular inflammation. Many malignant entities such as non-Hodgkin's lymphomas may masquerade as uveitis. We report a case of an HIV-positive patient with masquerade syndrome presenting unilateral uveitis. 45-year-old Caucasian man with a diagnosis of diffuse large B-cell lymphoma (DLBCL). The patient was diagnosed by a biopsy of an abdominal mass which showed fragments of gastric mucosa with diffuse growth of neoplastic cells. At diagnosis, the patient suffered from unilateral blurring of vision and a sudden decrease of left-eye visual acuity. A slit-lamp examination of the left eye revealed a diagnosis of anterior uveitis. The patient exhibited no signs of posterior uveitis. An anterior-chamber paracentesis was performed and analyzed by multiparameter flow cytometry (MFC), showing cells CD45, CD19, CD20, CD22, and CD38 positives, and moderate expression of CD10 with kappa light chain restriction, showing a monoclonal B-cell population. The patient received CHOP-R with intrathecal methotrexate followed by consolidation high dose methotrexate obtaining a complete response which is ongoing. Differential diagnosis between chronic uveitis and ocular lymphoma may be challenging. We advocate anterior-chamber paracentesis in cases of refractory uveitis in patients with hematologic malignancies. © 2016 International Clinical Cytometry Society. © 2016 International Clinical Cytometry Society.

Controlled ovarian hyperstimulation is an important step in infertility treatment. In some cases, however, ovar-ian hyperstimulation syndrome (OHSS) can occur. In its severe forms, ascites is likely to develop, associated with dyspnea. The aim of this study was to explore the usefulness of Ascites Index (AsI), a new tool for quantitative determination of ascites in patients with OHSS, to obtain data for planning further trials. Twelve patients with OHSS and ascites were included in the study. All patients were admitted to the hospital because of abdominal pain and dyspnea due to increasing ascites. Ultrasound measurements of ascites extent were performed in four external quadrants of the abdomen. Pockets of free fluid were measured. The obtained values were totaled, forming the Ascites Index (AsI), similarly to the amniotic fluid index. Because of dyspnea, paracentesis was performed in all cases. Median AsI at which patients reported dyspnea was 29.0 cm (range 21.6-38.6 cm). At AsI values less than 21.6 cm, no dyspnea was observed in any of the 12 studied patients. To avoid complications, 2000 mL of ascitic fluid was collected in each patient. After paracentesis, range of AsI decreased to 12.1-14.5 cm. The proposed AsI seems to be a promising tool for estimating and monitoring the ascites extent in OHSS. It can be estimated using basic ultrasound equipment. AsI requires further studies for standardization and transferability to other causes of ascites.

Catumaxomab: malignant ascites: unjustified marketing authorisation.

PubMed

2010-10-01

The only treatment for malignant ascites in patients with refractory cancer is paracentesis, a procedure to relieve symptoms. Catumaxomab, a monoclonal antibody, is now authorised in the European Union for intraperitoneal administration to patients with epithelial cancers that overexpress epithelial cellular adhesion molecule (EpCAM) and provoke ascites unresponsive to chemotherapy. Clinical evaluation of catumaxomab in this setting is based on a comparative, randomised but unblinded trial including 258 patients. Patients in the catumaxomab group had four paracenteses over a 10-day period, followed by a 6-hour intraperitoneal catumaxomab infusion, while patients in the control group had a single paracentesis. Catumaxomab did not extend median survival time, which was about two months. Methodological biases rule out any conclusions as to whether catumaxomab reduced the number of paracenteses needed during this short survival period. In this trial, 80% of patients treated with catumaxomab experienced serious adverse events, versus 29% of controls, resulting in hospitalisation in respectively about 29% versus 16% of patients. Two-thirds of patients had reactions linked to intraperitoneal catumaxomab infusion. Gastrointestinal disorders were frequent, and included abdominal pain, nausea and vomiting. Catumaxomab is hepatotoxic. In addition, most patients develop anti-catumaxomab antibodies, although the clinical consequences are unclear. Catumaxomab therapy is inconvenient: it lasts 10 days and requires 4 intraperitoneal infusions that last 6 hours each and require 24-hour monitoring. In practice, catumaxomab has more harms than benefits. It is better to focus on individually tailored palliative care for these terminally ill patients.

Chylous ascites is an extremely rare complication of abdominal aortic surgery. A case with a successful outcome is presented, followed by a review of the 17 published cases. Chylous ascites can result in nutritional imbalance, immunological deficit and respiratory dysfunction. Paracentesis confirms the diagnosis and provides symptomatic relief. Conservative management, beginning with a low-fat diet and medium-chain triglyceride (MCT) supplementation, is recommended, changing to total parenteral nutrition if unsuccessful. Failure of non-operative treatment may necessitate the need for laparotomy and ligation of leaking lymphatics or peritoneovenous shunting.

Chylous ascites is an unusual condition with many causes. Two cases are presented in which it appeared to be related to whole pelvis irradiation in one patient for carcinoma of the vagina and in another for carcinoma of the vulva. The diagnosis is made by paracentesis and analysis of the fluid. The underlying disease usually requires identification by exploratory laparotomy. Although a malignant process is the most common cause, the only findings in the authors' cases were widespread radiation changes in the intestine. After diagnosis treatment by low-fat diet with medium-chain triglyceride supplements resulted in disappearance of chylous ascites.

Ascitic fluid antibody produced in C57/B1 mice immunized with Friend leukemogenic virus exhibited potent neutralizing activity. In vitro neutralization tests revealed that a mean neutralization index of 3.0 was achieved, and it was shown by sucrose gradient ultracentrifugation that this antibody resembled the 7S type. A mean yield of 6.7 ml of fluid per mouse per weekly paracentesis was obtained over an 8-week period. The ascitic fluid antibody to Friend virus was also active in vivo. Mice given antibody 3, 5, 7, and 9 days after infection with Friend virus did not develop the splenomegaly characteristic of Friend disease. PMID:16349755

Human albumin: old, new, and emerging applications.

PubMed

Rozga, Jacek; Piątek, Tomasz; Małkowski, Piotr

2013-05-10

Human serum albumin has been widely used in an array of clinical settings for nearly 7 decades. Although there is no evidence to support the use of albumin rather than crystalloid in acute volume resuscitation, many clinicians continue to use albumin because it has other important physiologic effects besides the oncotic function. In keeping with the improved understanding of albumin physiology and pathophysiology of many acute and chronic diseases, use of albumin for medical applications has increased in recent years. This, along with increased costs of manufacturing and lower production volume of medical-grade albumin, has lead to an ongoing shortage and rapid increase in albumin prices. This review is based on the analysis of major publications, related to albumin chemistry, physiology, and medical uses including guidelines developed by professional and governmental organizations. Results reflect current knowledge about the role of albumin in health and disease and relevance of albumin therapy in specific clinical settings. Albumin therapy is currently recommended in spontaneous bacterial peritonitis with ascites, refractory ascites not responsive to diuretics, large-volume paracentesis, post-paracentesis syndrome, and the treatment of hepatorenal syndrome as an adjunct to vasoconstrictors. New indications for albumin therapy are linked to the antioxidant activity of albumin and its effects on capillary integrity. In recent years, large-pore hemofiltration and albumin exchange have emerged as promising liver support therapies for liver failure and other toxic syndromes. They are designed to remove a broad range of blood-borne toxins and to restore normal functions of the circulating albumin by replacing defective forms of albumin and albumin molecules saturated with toxins with normal albumin. In view of the ongoing worldwide shortage and high cost of human albumin (native and recombinant), new usage criteria, protocols, and guidelines for appropriate utilization

We treated 346 patients with otitis media with effusion (OME) and 30 (127 episodes) with recurrent acute suppurative otitis media at our outpatient clinic in the 6 years from October 1994 to September 2000. Of these, children under 15 years old numbered 185, mostly boys at a ratio of 1.4: 1.0, while patients aged 15 years or older numbered 161, mostly females at a ratio of 1.3: 1.0. In children, 24 were excluded due to a lack of diagnostic follow-up, 65 (40%) patients improved in conservative management of medication with and without repeated tubal inflation, 79 (49%) improved by paracentesis, and 18 (11%) recovered with the use of pressure equalization tubes (grommets). Of cases aged 15 years or older, follow-up was not possible in 28. Three (2%) were free of OME by conservative treatment, 116 (87%) improved by paracentesis, and 9 (7%) by using tubes. The mean durations of tube insertion was 11.3 months in children and 7.2 months in adults, but 5 adults (4%) continue being treated of this writing. Bilateral cases were 30% of children and 8% of adults with 73% of children affected bilaterally having persistence or recurrence. Acute purulent otitis media progressed to OME in 22% of children but only in 3% of patients aged 15 or older. In 36% of children and 26% of patients aged 15 or older, acute upper respiratory tract infection coincided with or predisposed to OME. Rhinosinusitis was seen in 19% of children and 14% of adults. Coincident allergic rhinitis was seen in 14% of children and 12% of adults with OME. Nasopharyngeal infection and allergy are likely related to OME development. The peak incidence of OME was similar to that of recurrent suppurative otitis media in children, so a seminal precipitating factor appears to result in these 2 conditions.

The purpose of this systematic review was to (1) characterize cases of fluid extravasation during hip arthroscopy and explore common factors among them and (2) describe management strategies and outcomes of this complication. The databases MEDLINE, EMBASE, and PubMed were searched and screened in duplicate. Data regarding patient demographics, fluid management, presentation, management, and outcomes were collected. Study quality was assessed in duplicate using the Methodological Index for Non-Randomized Studies Criteria. Fourteen studies (1,286 patients) were included. Twenty-two occurrences of symptomatic fluid extravasation were reported in 21 patients (1.6% of total patients; one patient had fluid extravasation during 2 separate hip arthroscopies). Two studies of normal fluid extravasation in asymptomatic patients reported 1.13 to 3.06 L of extravasated fluid observed on computed tomography. Nine case studies were included, which provided detailed patient and surgical information. Of these 9 patients (10 cases) with a mean age of 38.2 years old (range, 15 to 55 years), 6 were female. Signs of fluid extravasation included abdominal distension (89%), hypothermia (56%), hypotension. and metabolic acidosis (33% each). Four patients required surgical intervention, while 3 underwent paracentesis. Two patients were managed conservatively. All patients stabilized and were discharged, with one patient reporting abdominal complaints at latest follow-up (length of follow-up unspecified). Fluid extravasation is a rare but potentially life-threatening complication of hip arthroscopy. It is important for surgeons and anaesthesiologists to be aware of its existence in order to recognize and manage it promptly. Most patients require interventional management by surgery or paracentesis, but some stabilize with conservative management. Level IV, systematic review of Level IV studies.

Mirshahi, A; Scharioth, G B

2009-01-01

To present a surgical technique for treatment of peripheral anterior synechiae (PAS or goniosynechiae) at the operative field during nonpenetrating glaucoma surgery. After usual preparation of a superficial and a deep scleral flap with externalization of the Schlemm's canal and peeling the juxtacanalicular trabecular meshwork, the goniosynechia is transected by a spatula introduced to the anterior chamber through a paracentesis. A Descemet's window provides full visual control at the peripheral cornea at the basis of the superficial scleral flap. With this surgical technique, selective treatment of goniosynechiae is possible exactly at the area where creation of low outflow resistance is intended by the surgeon during nonpenetrating glaucoma surgery. This technique enables the surgeon to perform nonpenetrating glaucoma surgery even in the presence of peripheral anterior synechiae.

We present an improvised technique of infusion that uses a trocar cannula as an anterior chamber maintainer (ACM). Although routinely used in posterior segment surgery, the trocar cannula has been infrequently used in complex anterior segment procedures. The trocar ACM creates a transconjunctival biplanar wound of appropriate size that is self-sealing and overcomes the shortcomings of an ACM, such as spontaneous extrusion and forced introduction into the eye from variability in the size of the corneal paracentesis incision. Constant infusion inflow through the trocar ACM is used to maintain positive intraocular pressure through a self-sealing sclerotomy incision at the limbus.

Primary intestinal lymphangiectasia is a lymphatic system's disorder, where lymphatic drainage is blockaged. Clinically it produces malabsorption, protein-losing enteropathy, hypogammaglobulin in blood, and several degrees of malnutrition. Its treatment is not easy and includes dietetic-therapy and drugs. A 35-year-old-woman case report is exposed. She has recurrent chylosa ascites, requiring several admissions and evacuatory paracentesis. After food-fat was replaced by medium-chain triacyl-glicerol-enriched diet, a clinical, analytical and anthropometric improvement was demonstrated. The major way of treatment in intestinal lymphangiectasia in this case is the employement of specific-diet and adaptaded-basic-food. It's difficult and high collaboration of the patient is required, being necessary medical revisions during the whole life, due to the not well known evolution of this long-standing disease.

Phase II: A randomized, placebo-controlled cross-over design with four dogs per group where carprofen was given 4.4 mg/kg/day on day (D) 1, 2 and 3. ACP was performed at T0 and T1.5 on D3. Statistical analysis was performed with repeated measures anova and post hoc Tukey-Kramer multiple-comparison procedure. In phase II, TNF-α level was analyzed with a Wilcoxon signed-rank test. Phase I: PGE(2) significantly increased (P < 0.0001) to plateau at T4. NO(X) was decreased at T4 (P < 0.06), but increased at T8 (P < 0.0001). COX-2 showed detectable expression only at T8. TNF-α, NOS-2, MMP-3 and -9 were undetectable at all time points. Phase II: At T1.5, PGE(2) was significantly elevated in both groups but was lower in the carprofen group (P = 0.037). NO(x) and TNF-α did not statistically increase in either group. Following ACP, significant increases in PGE(2) levels confirmed inflammation characterized by a rise of COX-2. The NO(x) pathway took longer to induce as compared with PGE(2) . Carprofen decreased PGE(2) levels and could help control intraocular inflammation. © 2011 American College of Veterinary Ophthalmologists.

Late endophthalmitis, due to Propionibacterium acnes, developed in three patients following uncomplicated extracapsular cataract extraction and posterior chamber intraocular lens (PC-IOL) insertion. Cultures from the capsular bag yielded P. acnes in all three. With topical anesthesia and through an anterior chamber paracentesis, culture specimens were taken from and clindamycin irrigated into the capsular bag. Filtered 100% oxygen was introduced into the anterior chamber in two; the third also received an injection of gentamicin and dexamethasone into the capsular bag. After treatment, two patients received oral antibiotics; one received hyperbaric oxygen therapy. Visual acuity was improved and inflammation reduced in all three. However, after treatment, ocular toxic effects due to clindamycin were suspected in one. This approach offers several clear advantages, including topical anesthesia, outpatient management, elimination of the need for vitrectomy, and retention of the intraocular lens (IOL).

Two of the most common liver abscess is anamoebic liver abscess and pyogenic liver abscess (PLA). PLA could be as singular or multiple abscesses. It is usually caused by Klebsiella pneumonia and Escherichia coli. Historically, PLA is usually caused by acute appendicitis, but with developed of surgical practice and microbiology, the number of events has decreased. Here we present a case of a39-year-old woman that developed a PLA after she had an appendectomy about six months ago. An ultrasonogram and abdominal scan showed an abscess in the right lobe. We performed paracentesis, and the result from the pus culturewas positive for Escherichia coli with Extended-Spectrum Beta-Lactamase (ESBL) (+) that showed the same as the culture from lesion taken from her appendix. This report emphasizes the fact that, nowadays we still found Pyogenic liver abscess after peritonitis appendix perforation.

A liver abscess often occurs in low-middle income countries such as Indonesia. Two most common liver abscesses are amoebic and pyogenic liver abscess. Data that reported tuberculosis liver abscess (TLA) is extremely rare. A diagnostic criterion for tuberculosis liver abscess is rare and remains unclear. A 52-year-old man developed a TLA which was not associated with any pulmonary or gastrointestinal tract foci of tuberculosis. An ultrasonogram and abdominal scan showed an abscess in the right lobe. We performed paracentesis, and the pus from the lesion was positive tubercular bacilli on acid-fast bacilli staining. The patient was started on systemic antitubercular therapy to which he responded favorably. This report emphasizes the fact that, although a TLA is a very rare entity, it should be included in the differential diagnosis of liver abscess especially in Indonesia where the prevalence of tuberculosis is extremely high.

Intra-abdominal hypertension and abdominal compartment syndrome have been increasingly recognized as a hip arthroscopy complication over the past decade. In the absence of consensus definitions and treatment guidelines, the diagnosis and management of intra-abdominal hypertension and abdominal compartment syndrome remains variable from institution to institution. We report the occurrence of the extravasation of fluid into the abdomen during arthroscopic treatment of femoroacetabular impingement combined with resection of trochanteric bursa and our management of the condition in a 55-year old Caucasian woman. We present an algorithm of treatment of abdominal compartment syndrome, as a hip arthroscopy complication, according to the consensus definitions and recommendations of the World Society of the Abdominal Compartment Syndrome. In the algorithm options, we have included paracentesis and percutaneous catheter decompression as the main point of treatment. Our algorithm will have a broader clinical impact on orthopedic surgery, anesthesiology and emergency medicine.

Necrotizing viral retinitis is associated with infection by the Herpes family of viruses, especially herpes simplex virus (HSV), varicella zoster virus (VZV) and occasionally cytomegalovirus (CMV). When the diagnosis is suspected clinically, antiviral therapy must be instituted immediately. We report the case of a patient presenting with necrotizing viral retinitis 3 months following intravitreal injection of triamcinolone acetonide for diabetic macular edema. Fluorescein angiography demonstrated a superior temporal occlusive vasculitis. A diagnostic anterior chamber paracentesis was performed to obtain deoxyribo-nucleic acid (DNA) for a polymerase chain reaction (PCR) test for viral retinitis. PCR was positive for CMV. The patient was placed on intravenous ganciclovir. CMV retinitis is exceedingly rare in immunocompetent patients; however, it remains the most common cause of posterior uveitis in immunocompromised patients. The incidence of this entity remains unknown. Local immunosuppression, the dose and the frequency of injections may explain the occurrence of this severe retinitis. Copyright © 2013.

Recent data do not exist on medical students' performance of and attitudes toward procedural and interpretive skills deemed important by medical educators. A total of 171 medical students at seven medical schools were surveyed regarding frequency of performance, self-confidence, and perceived importance of 21 procedural and interpretive skills. Of the 122 responding students (71% response rate), a majority had never performed lumbar puncture, thoracentesis, paracentesis, or blood culture, and students reported lowest self-confidence in these skills. At least one-quarter of students had never performed phlebotomy, peripheral intravenous catheter insertion, or arterial blood sampling. Students perceived all 21 skills as important to learn and perform during medical school. Through the third year of medical school, a majority of students had never performed important procedures, and a substantial minority had not performed basic procedures. Students had low self-confidence in skills they rarely performed, but perceived all skills surveyed as important.

Recent data do not exist regarding fourth-year medical students' performance of and attitudes toward procedural and interpretive skills, and how these differ from third-year students'. Cross-sectional survey conducted in February 2006 of 122 fourth-year students from seven U.S. medical schools, compared with their responses in summer 2005. Students estimated their cumulative performance of 22 skills and reported self-confidence and perceived importance using a five-point Likert-type scale. The response rate was 79% (96/122). A majority reported never having performed cardioversion, thoracentesis, cardiopulmonary resuscitation, blood culture, purified protein derivative placement, or paracentesis. One fifth of students had never performed peripheral intravenous catheter insertion, phlebotomy, or arterial blood sampling. Students reported increased cumulative performance of 17 skills, increased self-confidence in five skills, and decreased perceived importance in three skills (two-sided P < .05). A majority of fourth-year medical students still have never performed important procedures, and a substantial minority have not performed basic procedures.

A totally implantable system for providing access to the peritoneal cavity was evaluated. Fifty-six Port-A-Cath (Pharmacia Nu Tech, Piscataway, NJ) peritoneal access systems were implanted in 54 cancer patients receiving intraperitoneal chemotherapy. The catheters are accessed by transcutaneous placement of a Huber point needle through a silicone septum at the top of the portal. A total of 32 patient years of experience are reported. The Port-A-Caths have been in place for a median of 22 weeks (range, one to 85). A total of 401 entries have been made for paracentesis, chemotherapy administration, antibiotic administration, peritoneal lavage for cytology, and catheter flushing. There have been six episodes of peritonitis (five Staphylococcus epidermidis, one S aureus) in three patients. There have been no mechanical failures of the Port-A-Caths. Loss of bidirectional flow through the catheter due to fibrin deposition about the catheter has been the major cause of catheter failure. Patient acceptance of the Port-A-Cath has been excellent.

Chylous Ascites: Evaluation and Management

PubMed Central

Al-Busafi, Said A.; Ghali, Peter; Deschênes, Marc; Wong, Philip

2014-01-01

Chylous ascites refers to the accumulation of lipid-rich lymph in the peritoneal cavity due to disruption of the lymphatic system secondary to traumatic injury or obstruction. Worldwide, abdominal malignancy, cirrhosis, and tuberculosis are the commonest causes of CA in adults, the latter being most prevalent in developing countries, whereas congenital abnormalities of the lymphatic system and trauma are commonest in children. The presence of a milky, creamy appearing ascitic fluid with triglyceride content above 200 mg/dL is diagnostic, and, in the majority of cases, unless there is a strong suspicion of malignancy, further investigations are not required in patients with cirrhosis. If an underlying cause is identified, targeted therapy is possible, but most cases will be treated conservatively, with dietary support including high-protein and low-fat diets supplemented with medium-chain triglycerides, therapeutic paracentesis, total parenteral nutrition, and somatostatins. Rarely, resistant cases have been treated by transjugular intrahepatic portosystemic shunt, surgical exploration, or peritoneovenous shunt. PMID:27335837

BACKGROUND: A patient with AIDS who developed the clinical picture of bilateral progressive outer retinal necrosis (PORN) in combination with varicella zoster encephalitis is described. The picture developed more than 2 years after an episode of ophthalmic zoster infection, and following intermittent exposure to oral acyclovir because of recurrent episodes of cutaneous herpes simplex infection. METHODS: Aqueous humour, obtained by paracentesis of the anterior chamber, was analysed using immunofluorescence and polymerase chain reaction (PCR). Postmortem analysis of eye and brain tissue was performed by using conventional techniques and in situ hybridisation. RESULTS: While conventional techniques all failed to detect a causative agent, analysis of the aqueous humour using PCR, and histological examination of necropsy specimens from eyes and brain using in situ hybridisation were conclusive for the diagnosis varicella zoster virus (VZV) infection. CONCLUSION: This case documents the presumed association of PORN and VZV encephalitis in a severely immunocompromised AIDS patient. Images PMID:8976726

An 85-year-old woman was admitted to our hospital for steroid therapy for relapsing nephrotic syndrome. During hospitalization, she complained of sudden epigastric pain at night. Although there were signs of peritoneal irritation, CT showed a large amount of ascitic fluid, but no free intraperitoneal gas. Gram staining of ascitic fluid obtained by abdominal paracentesis showed Gram-negative rods, which raised a strong suspicion of gastrointestinal perforation and peritonitis. Therefore, emergency surgery was performed. Exploration of the colon showed multiple sigmoid diverticula, one of which was perforated. The patient underwent an emergency Hartmann's procedure. Imaging studies failed to reveal any evidence of gastrointestinal perforation, presenting a diagnostic challenge. However, a physician performed rapid Gram staining of ascitic fluid at night when laboratory technicians were absent, had a strong suspicion of gastrointestinal perforation, and performed emergency surgery. Gram staining is superior in rapidity, and ascitic fluid Gram staining can aid in diagnosis, suggesting that it should be actively performed. We report this case, with a review of the literature on the significance of rapid diagnosis by Gram staining.

Pathophysiology and management of pediatric ascites.

PubMed

Sabri, Mahmoud; Saps, Miguel; Peters, John M

2003-06-01

Ascites accumulation is the product of a complex process involving hepatic, renal, systemic, hemodynamic, and neurohormonal factors. The main pathophysiologic theories of ascites formation include the "underfill," "overflow," and peripheral arterial vasodilation hypotheses. These theories are not necessarily mutually exclusive and are linked at some level by a common pathophysiologic thread: The body senses a decreased effective arterial blood volume, leading to stimulation of the sympathetic nervous system, arginine-vasopressin feedback loops, and the renin-angiotensin-aldosterone system. Cornerstones of ascites management include dietary sodium restriction and diuretics. Spironolactone is generally tried initially, with furosemide added if clinical response is suboptimal. More refractory patients require large-volume paracentesis (LVP) accompanied by volume expansion with albumin. Placement of a transjugular intrahepatic portosystemic shunt is reserved for individuals with compensated liver function who require very frequent sessions of LVP. Peritoneovenous shunts are not used in contemporary ascites management. Liver transplantation remains the definitive therapy for refractory ascites. Although treatment of ascites fails to improve survival, it benefits quality of life and limits the development of such complications as spontaneous bacterial peritonitis.

Limited training, high cost, and low equipment mobility leads to inaccuracies in decision making and is concerning with serious ocular injuries such as suspected ruptured globe or post-operative infections. Here, we present a novel point-of-service (POS) quantitative ascorbic acid (AA) assay with use of the OcuCheck Biosensor. The present work describes the development and clinical testing of the paper-based biosensor that measures the changes in electrical resistance of the enzyme-plated interdigitated electrodes to quantify the level of AA present in ocular fluid. We have demonstrated the proof-of-concept of the biosensor testing 16 clinical samples collected from aqueous humor of patients undergoing therapeutic anterior chamber paracentesis. Comparing with gold standard colorimetric assay for AA concentration, OcuCheck showed accuracy of >80%, sensitivity of >88% and specificity of >71%. At present, there are no FDA-approved POS tests that can directly measures AA concentration levels in ocular fluid. We envisage that the device can be realized as a handheld, battery powered instrument that will have high impact on glaucoma care and point-of-care diagnostics of penetrating ocular globe injuries.

[Facial paralysis in children].

Facial paralyses in children may be grouped under headings displaying a certain amount of individuality. Chronologically, first to be described are neonatal facial paralyses. These are common and are nearly always cured within a few days. Some of these cases are due to the mastoid being crushed at birth with or without the use of forceps. The intra-osseous pathway of the facial nerve is then affected throughout its length. However, a cure is often spontaneous. When this desirable development does not take place within three months, the nerve should be freed by decompressive surgery. The special anatomy of the facial nerve in the new-born baby makes this a delicate operation. Later, in all stages of acute otitis, acute mastoiditis or chronic otitis, facial paralysis can be seen. Treatment depends on the stage reached by the otitis: paracentesis, mastoidectomy, various scraping procedures, and, of course, antibiotherapy. The other causes of facial paralysis in children are very much less common: a frigore or viral, traumatic, occur ring in the course of acute poliomyelitis, shingles or tumours of the middle ear. To these must be added exceptional causes such as vitamin D intoxication, idiopathic hypercalcaemia and certain haemopathies.

Recently tenofovir disoproxil fumarate (TDF) has been widely used as a first-line therapy for chronic hepatitis B (CHB) infection. Although TDF demonstrates successful viral suppression, the possibility of renal failure and lactic acidosis has been proposed with TDF administration, especially in human immunodeficiency virus co-infected patients. However, TDF induced lactic acidosis has never been reported in CHB mono-infected patients. A 59-year-old man received TDF for hepatitis B associated with cirrhosis. After ten days of TDF administration, nausea, vomiting and abdominal pain developed. High anion gap acidosis with elevated lactate level (pH 7.341, pCO2 29.7 mmHg, HCO3- 15.6mmHg, lactate 3.2mmol/L, anion gap 15.4 mEq/L) was developed. With no infection, normal diagnostic paracentesis, and urinalysis together with high anion gap and increased blood lactate levels suggested lactic acidosis. TDF was stopped, and haemodialysis was performed to control lactic acidosis. Although stopping TDF instantly and treating lactic acidosis using hemodialysis, the patient died. Although, Fatal lactic acidosis is very rare in TDF patient, however, decompensated cirrhotic patients should be closely observed to keep the possibility of lactic acidosis in mind.

Background & Objectives: Chyloascites is a rare complication that can result from abdominal trauma, neoplasm, inflammatory conditions, or various abdominal surgeries. Few cases have been described secondary to iatrogenic injury from laparoscopic Nissen fundoplication. We describe a case in which this surgery resulted in chyloascites that was successfully treated by lymphatic glue embolization. Methods: A 37-year-old male presented with signs and symptoms consistent with chronic reflux disease. He underwent an uneventful laparoscopic Nissen fundoplication. Two weeks postoperatively, he was admitted for dehydration. During his admission, he began to develop a persistent cough, shortness of breath, and abdominal distention. Imaging and fluid analysis from thoracocentesis and paracentesis were consistent with chyle leakage. Despite nonoperative measures, the patient's presentation persisted. Results: Thoracic duct ligation was performed without success. Bipedal lymphangiography identified an extensive leak revealing a severely lacerated thoracic duct spilling contrast freely into the abdomen and no contrast entering the thoracic duct in the chest. The site of injury was successfully sealed off with percutaneous glue embolization through lymph channels. Conclusion: Chyloascites is a rare complication of laparoscopic Nissen fundoplication. When not successful with conservative measures, lymphatic glue embolization can provide effective treatment. PMID:23477184

Deep Needle Procedures: Improving Safety With Ultrasound Visualization

Abstract Promoting patient safety and increasing health care quality have dominated the health care landscape during the last 15 years. Health care regulators and payers are now tying patient safety outcomes and best practices to hospital reimbursement. Many health care leaders are searching for new technologies that not only make health care for patients safer but also reduce overall health care costs. New advances in ultrasonography have made this technology available to health care providers at the patient’s bedside. Point-of-care ultrasound assistance now aids providers with real-time diagnosis and with visualization for procedural guidance. This is especially true for common deep needle procedures such as central venous catheter insertion, thoracentesis, and paracentesis. There is now mounting evidence that clinician-performed point-of-care ultrasound improves patient safety, enhances health care quality, and reduces health care cost for deep needle procedures. Furthermore, the miniaturization, ease of use, and the evolving affordability of ultrasound have now made this technology widely available. The adoption of point-of-care ultrasonography has reached a tipping point and should be seriously considered the safety standard for all hospital-based deep needle procedures. PMID:24786918

To evaluate the diagnostic value of polymerase chain reaction (PCR) performed on aqueous humour for the detection of viral DNA in patients with necrotising herpetic retinitis. The clinical features and laboratory results of 22 patients (29 eyes) presenting with necrotising herpetic retinitis between March 1999 and June 2001 were reviewed retrospectively. Aqueous humour was obtained after anterior chamber paracentesis and PCR was performed in all cases. Viral DNA was detected in the aqueous humour of 19 patients (86.4%). Epstein-Barr virus (EBV) seroconversion was evidenced in one additional patient. In the acute retinal necrosis (ARN) group (n = 19), varicella zoster virus (VZV) DNA was identified in six patients, herpes simplex virus 1 (HSV-1) DNA in two patients, herpes simplex virus 2 (HSV-2) DNA in four patients, and cytomegalovirus (CMV) genome in four patients. In the progressive outer retinal necrosis (PORN) group (n = 3), VZV DNA was detected in all patients. No sample was positive for more than one virus. PCR analysis of aqueous humour in patients with clinical features of necrotising viral retinitis can provide specific aetiological orientation and the method appears to be safe and highly sensitive.

Central retinal artery occlusion (CRAO) is an ocular emergency and most of the cases present with painless sudden persistent loss of vision in the range of counting fingers to perception of light. The presentation of CRAO is associated with a variety of medical conditions. We report a rare case of CRAO associated with persistent truncus arteriosus (PTA) and single atrium in a female patient. A 23-year-old woman was admitted due to sudden painless visual loss in the left eye. On examination visual acuity of light-perception was noted in the left eye with a left relative afferent pupillary defect. Fundoscopic examination revealed retinal ischemic whitening, constriction of the arteriole and venule with segmentation and typical "cherry-red spot" suggesting CRAO. The patient was treated with ocular massage and anterior chamber paracentesis. She was commenced on 150 mg of aspirin and also received hyperbaric oxygen therapy. An echocardiogram revealed PTA and single atrium. A diagnosis of CRAO associated with PTA and single atrium was made. The ophthalmologist should enquire about congenital and acquired cardiac abnormalities in patients with CRAO and consider such abnormalities to be possible sources of emboli.

Turmeric (Curcuma longa) is a popular Indian spice that has been used for centuries in herbal medicines for the treatment of a variety of ailments such as rheumatism, diabetic ulcers, anorexia, cough and sinusitis. Curcumin (diferuloylmethane) is the main curcuminoid present in turmeric and responsible for its yellow color. Curcumin has been shown to possess significant anti-inflammatory, anti-oxidant, anti-carcinogenic, anti-mutagenic, anticoagulant and anti-infective effects. This review summarizes and discusses recently published papers on the key biomedical applications of curcumin based materials. The highlighted studies in the review provide evidence of the ability of curcumin to show the significant vitro antioxidant, diabetic complication, antimicrobial, neuroprotective, anti-cancer activities and detection of hypochlorous acid, wound healing, treatment of major depression, healing of paracentesis, and treatment of carcinoma and optical detection of pyrrole properties. Hydrophobic nature of this polyphenolic compound along with its rapid metabolism, physicochemical and biological instability contribute to its poor bioavailability. To redress these problems several approaches have been proposed like encapsulation of curcumin in liposomes and polymeric micelles, inclusion complex formation with cyclodextrin, formation of polymer-curcumin conjugates, etc. Copyright © 2015 Elsevier B.V.

2016-01-01

Umbilical hernia occurs in 20% of the patients with liver cirrhosis complicated with ascites. Due to the enormous intraabdominal pressure secondary to the ascites, umbilical hernia in these patients has a tendency to enlarge rapidly and to complicate. The treatment of umbilical hernia in these patients is a surgical challenge. Ascites control is the mainstay to reduce hernia recurrence and postoperative complications, such as wound infection, evisceration, ascites drainage, and peritonitis. Intermittent paracentesis, temporary peritoneal dialysis catheter or transjugular intrahepatic portosystemic shunt may be necessary to control ascites. Hernia repair is indicated in patients in whom medical treatment is effective in controlling ascites. Patients who have a good perspective to be transplanted within 3-6 mo, herniorrhaphy should be performed during transplantation. Hernia repair with mesh is associated with lower recurrence rate, but with higher surgical site infection when compared to hernia correction with conventional fascial suture. There is no consensus on the best abdominal wall layer in which the mesh should be placed: Onlay, sublay, or underlay. Many studies have demonstrated several advantages of the laparoscopic umbilical herniorrhaphy in cirrhotic patients compared with open surgical treatment. PMID:27462389

Central retinal artery occlusion (CRAO) is an ophthalmologic emergency due to the sudden cessation of circulation to the inner retinal layer. Without immediate treatment, permanent blindness may ensue. Several treatment options exist, ranging from noninvasive medical management to thrombolysis. Nonetheless, ongoing debate exists regarding the best therapeutic strategy. The authors present the case of a 78-year-old woman with a medical history of hypercholesterolemia and rheumatoid arthritis who experienced complete loss of vision in her left eye. Following ophthalmologic evaluation demonstrating left CRAO, anterior chamber paracentesis was performed. Endovascular intervention was performed via local intra-arterial fibrinolysis with alteplase. Her vision returned to 20/20 following the procedure. In general, conventional therapies have not significantly improved patient outcomes. Several management options exist for CRAO. In general, conservative measures have not been reported to yield better patient outcomes as compared to the natural history of this medical emergency. Endovascular approaches are another option as observed with this case reported. In cases of CRAO, therapeutic strategies such as intra-arterial fibrinolysis utilize a local infusion of reactive tissue plasminogen activator directly at the site of occlusion via catheterization of the ophthalmic artery. Although several case series do show promising results after treating CRAO with intra-arterial fibrinolysis, further studies are required given the reports of complications.

Objective To assess the benefit of trans-jugular intrahepatic porto-systemic shunt (TIPS) placement for refractory ascites. Design A retrospective observational study of all patients undergoing TIPS for refractory ascites in our hospital between 2003 and 2012. Setting Secondary care. Patients Cirrhotic patients with refractory ascites. Main outcome measures We examined direct real-world (National Health Service) health related costs in the year before and after the TIPS procedure took place. Data were collected relating to the need for reintervention and hepatic encephalopathy. Results Data were available for 24 patients who underwent TIPS for refractory ascites (86% of eligible patients). TIPS was technically successful in all cases. Mean number of bed days in the year prior to TIPS was 30.3 and 14.3 in the year following (p=0.005). No patient had ascites at the end of the year after the TIPS with less requirement for paracentesis over the course of the year (p<0.001). Mean reduction in cost was £2759 per patient. TIPS was especially cost-effective in patients requiring between 6 and 12 drains per year with a mean saving of £9204 per patient. Conclusions TIPS is both a clinically effective and economically advantageous therapeutic option for selected patients with refractory ascites. PMID:28839725

[New etiological concepts in uveitis].

PubMed

Bodaghi, B

2005-05-01

Uveitis remains an important cause of visual impairment, particularly in young patients. Idiopathic forms of intraocular inflammation should no longer be regarded as a presumed clinical entity, and the ophthalmologist must reconsider the specific etiology of primary uveitis when the clinical examination does not yield a definitive diagnosis or when the course of the disease on corticosteroids remains atypical. Laboratory tests based on serum analysis have limited value and should not be considered as diagnostic proof in different clinical presentations. The diagnostic management of infectious uveitis has been greatly improved by the use of molecular techniques applied to ocular fluids and tissues. Polymerase chain reaction (PCR) technology is a powerful tool that should be proposed in atypical cases of uveitis or retinitis of unclear but potentially infectious origin. This strategy is a major step before using unconventional and new immunomodulatory agents such as anti-TNF-alpha molecules. Under strict experimental conditions including adequate testing to rule out a possible contamination, PCR and its variants have changed our practical approach to intraocular inflammatory disorders and have provided new details for the understanding of infectious uveitis. The concept of pathogen-induced intraocular inflammation can be revisited in the light of molecular data obtained after anterior chamber paracentesis or diagnostic vitrectomy.

  To describe sequential phacoemulsification-intraocular lens (IOL) implantation-posterior capsulorhexis-anterior vitrectomy in the management of phakic malignant glaucoma.   Twenty consecutive patients (25 eyes) with phakic malignant glaucoma were enrolled at the Zhongshan Ophthalmic Center, Sun Yat-sen University. All patients underwent phacoemulsification, IOL implantation and posterior capsulorhexis together with anterior vitrectomy via a clear corneal paracentesis. Visual acuity, intraocular pressure (IOP), anterior chamber depth (ACD), surgical complications and medications required after the surgery were recorded.   After surgery, the mean LogMAR visual acuity and ACD increased significantly (visual acuity from -1.56 ± 1.17 to -0.54 ± 0.81, p < 0.001; ACD from 0.367 ± 0.397 mm to 2.390 ± 0.575 mm, p < 0.001), and mean IOP decreased significantly (from 39.6 ± 10.6 mm Hg to 14.5 ± 4.1 mmHg, p < 0.001). No serious perioperative complications occurred, and only five eyes required topical glaucoma medications after surgery.   Combined phacoemulsification-IOL implantation-posterior capsulorhexis-anterior vitrectomy surgery is a safe and effective method for treating patients with phakic malignant glaucoma. © 2012 The Authors.

Bedside point-of-care ultrasound (POCUS) is increasingly used to assess medical patients. At present, no consensus exists for what POCUS curriculum is appropriate for internal medicine residency training programs. This document details the consensus-based recommendations by the Canadian Internal Medicine Ultrasound (CIMUS) group, comprising 39 members, representing 14 institutions across Canada. Guiding principles for selecting curricular content were determined a priori. Consensus was defined as agreement by at least 80% of the members on POCUS applications deemed appropriate for teaching and assessment of trainees in the core (internal medicine postgraduate years [PGY] 1-3) and expanded (general internal medicine PGY 4-5) training programs. We recommend four POCUS applications for the core PGY 1-3 curriculum (inferior vena cava, lung B lines, pleural effusion, and abdominal free fluid) and three ultrasound-guided procedures (central venous catheterization, thoracentesis, and paracentesis). For the expanded PGY 4-5 curriculum, we recommend an additional seven applications (internal jugular vein, lung consolidation, pneumothorax, knee effusion, gross left ventricular systolic function, pericardial effusion, and right ventricular strain) and four ultrasound-guided procedures (knee arthrocentesis, arterial line insertion, arterial blood gas sampling, and peripheral venous catheterization). These recommendations will provide a framework for training programs at a national level.

To assess the benefit of trans-jugular intrahepatic porto-systemic shunt (TIPS) placement for refractory ascites. A retrospective observational study of all patients undergoing TIPS for refractory ascites in our hospital between 2003 and 2012. Secondary care. Cirrhotic patients with refractory ascites. We examined direct real-world (National Health Service) health related costs in the year before and after the TIPS procedure took place. Data were collected relating to the need for reintervention and hepatic encephalopathy. Data were available for 24 patients who underwent TIPS for refractory ascites (86% of eligible patients). TIPS was technically successful in all cases. Mean number of bed days in the year prior to TIPS was 30.3 and 14.3 in the year following (p=0.005). No patient had ascites at the end of the year after the TIPS with less requirement for paracentesis over the course of the year (p<0.001). Mean reduction in cost was £2759 per patient. TIPS was especially cost-effective in patients requiring between 6 and 12 drains per year with a mean saving of £9204 per patient. TIPS is both a clinically effective and economically advantageous therapeutic option for selected patients with refractory ascites.

1. Enteral feeding and factors promoting hypoxia and ischaemia of the gut are thought to cause necrotising enterocolitis of the newborn but have not been proven as factors in the pathogenesis of NEC. Enteral feeding may be started in principle on the first day of life at a rate of 10-20 ml/kg/day. Controlled results to the contrary have not been published. 2. Drugs which have a high osmolarity should be diluted with milk as far as possible to avoid mucosal damage. 3. In cases of epidemic NEC, infants with proven disease should be isolated. The use of a bactericidal and virucidal disinfectant is imperative for hand disinfection. 4. Early diagnosis and early treatment are necessary to prevent progression to advanced stages. 5. Antibiotic treatment should be selected to cover the entire bacterial spectrum of the ward. 6. Frequent physical, radiological and ultrasound examinations should be done to monitor the course of the disease. Laboratory analyses should include: acid-basis status, leukocytes, differential blood picture, thrombocytes, C-reactive protein, haematocrit, serum electrolytes. 7. Large amounts of fluid may be necessary to prevent and treat hypovolaemic shock. 8. Abdominal paracentesis helps to recognise peritonitis and intestinal gangrene and allows surgical treatment as early as possible.

To investigate the levels of antioxidant enzymes catalase (CAT), glutathione peroxidase (GPO), superoxide dismutase (SOD), and malondialdehyde (MDA) in human eyes with primary open-angle glaucoma (POAG) and to correlate their concentrations with severity of glaucoma. A prospective cases control study. Thirty patients with primary open-angle glaucoma and twenty-five patients with senile cataracts of matched age and gender were included in the study prospectively. Aqueous humor samples were obtained by paracentesis at the time of elective surgery for glaucomatous and cataractous patients. Aqueous humor were analyzed for CAT, GPO, SOD, and MDA status. GPO, SOD, and MDA enzyme levels revealed a high significant increase in aqueous humor of POAG patients with respect to the comparative group of cataract patients (P < 0.001). No significant difference in the activity of CAT enzyme in aqueous humor of POAG and cataract patient (P = 0.201). Significant correlation was found between the MDA enzyme level and severe visual field loss (P < 0.001) in POAG patients. Increased levels of aqueous humor GPO, SOD, and MDA may be associated with POAG. In addition, they may be useful antioxidant enzyme levels in aqueous humor of POAG patients as a result of glaucoma disease and not a cause.

Malignant ascites: A review of prognostic factors, pathophysiology and therapeutic measures

Malignant ascites indicates the presence of malignant cells in the peritoneal cavity and is a grave prognostic sign. While survival in this patient population is poor, averaging about 20 wk from time of diagnosis, quality of life can be improved through palliative procedures. Selecting the appropriate treatment modality remains a careful process, which should take into account potential risks and benefits and the life expectancy of the patient. Traditional therapies, including paracentesis, peritoneovenous shunt placement and diuretics, are successful and effective in varying degrees. After careful review of the patient’s primary tumor origin, tumor biology, tumor stage, patient performance status and comorbidities, surgical debulking and intraperitoneal chemotherapy should be considered if the benefit of therapy outweighs the risk of operation because survival curves can be extended and palliation of symptomatic malignant ascites can be achieved in select patients. In patients with peritoneal carcinomatosis who do not qualify for surgical cytoreduction but suffer from the effects of malignant ascites, intraperitoneal chemotherapy can be safely and effectively administered via laparoscopic techniques. Short operative times, short hospital stays, low complication rates and ultimately symptomatic relief are the advantages of laparoscopically administering heated intraperitoneal chemotherapy, making it not only a valuable treatment modality but also the most successful treatment modality for achieving palliative cure of malignant ascites.

Chylous ascites occurring after abdominal surgery is rare. Despite being potentially critical, there is no definite treatment guideline because of its rarity. Here we present a case of massive chylous ascites occurring after rectal surgery which was successfully treated with an oral fat-free elemental diet (ED). A 67-year-old man underwent low anterior resection with para-aortic lymphadenectomy for advanced rectal cancer. Early postoperative course was uneventful and the patient was discharged from hospital 10 days after surgery; however, after discharge, abdominal distension rapidly developed. Abdominal computed tomography (CT) performed 3 weeks after surgery revealed massive ascites and laboratory findings showed remarkable hypoproteinemia and lymphopenia. Urgent diagnostic paracentesis showed the ascites to be a white milky fluid containing high levels of triglycerides (564 mg/dl), leading to a diagnosis of chyloperitoneum. Daily nutrition of the patient was entirely with a fat-free ED (30 kcal/kg/day of Elental(®), Ajinomoto Pharmaceutical Co. Ltd, Tokyo, Japan). After the initiation of oral Elental(®), abdominal distension, hypoproteinemia, and lymphopenia gradually improved. Abdominal CT performed 7 weeks after surgery showed no ascitic fluid in the abdomen, and thereafter a normal diet was initiated. Since then, no relapse of chyloperitoneum has been proven. As a result, the chylous ascites was successfully treated in the outpatient clinic.

Management of ascites and hepatorenal syndrome.

Ascites represents the most common decompensating event in patients with liver cirrhosis. The appearance of ascites is strongly related to portal hypertension, which leads to splanchnic arterial vasodilation, reduction of the effective circulating volume, activation of endogenous vasoconstrictor systems, and avid sodium and water retention in the kidneys. Bacterial translocation further worsens hemodynamic alterations of patients with cirrhosis and ascites. The first-line treatment of uncomplicated ascites is a moderate sodium-restricted diet combined with diuretic treatment. In patients who develop refractory ascites, paracentesis plus albumin represents the most feasible option. Transjugular intrahepatic portosystemic shunt placement is a good alternative for selected patients. Other treatments such as vasoconstrictors and automated low-flow pumps are two potential options still under investigations. Ascites is associated with a high risk of developing further complications of cirrhosis such as dilutional hyponatremia, spontaneous bacterial peritonitis and/or other bacterial infections and acute kidney injury (AKI). Hepatorenal syndrome (HRS) is the most life-threatening type of AKI in patients with cirrhosis. The most appropriate medical treatment in patients with AKI-HRS is the administration of vasoconstrictors plus albumin. Finally, ascites impairs both the quality of life and survival in patients with cirrhosis. Thus, all patients with ascites should be evaluated for the eligibility for liver transplantation. The aim of this article is to review the management of patients with cirrhosis, ascites and HRS.

Utility of the quantitative Ki-67 proliferation index and CD56 together in the cytologic diagnosis of small cell lung carcinoma and other lung neuroendocrine tumors.

Distinction of small cell lung carcinoma (SCLC) from non-small cell lung carcinoma (NSCLC) is critical because of the differences in prognosis and management. Patients with SCLC usually present with distant metastasis, and clinicians demand an accurate diagnosis in order to initiate appropriate therapy. Limited cytology material, occasionally with crush artifact, is not uncommon. Therefore, robust cytomorphologic features and a small immunostaining panel would be ideal to differentiate SCLC from NSCLC and other neuroendocrine neoplasms. We evaluated CD56 and the quantitative Ki-67 immunohistochemical panel in comparison to synaptophysin and chromogranin, along with cytomorphology to diagnose SCLC. Eighty-eight cases of SCLC were retrieved from the cytology archives of The Johns Hopkins Hospital. Forty neuroendocrine neoplasms were used as control cases. SCLCs included 33 lung cases and 55 metastatic lesions. The specimens were obtained by fine needle aspiration, thoracocentesis, bronchoalveolar lavage and abdominal paracentesis. CD56 was expressed in 98.9% of SCLCs, which is significantly more sensitive than synaptophysin and chromogranin. The Ki-67 labeling index was high (>70%) in all cases, which is a reliable marker to differentiate SCLC from other neuroendocrine neoplasms and NSCLC. CD56 and quantitative Ki-67 along with cytomorphology is a robust immunohistochemical panel to differentiate SCLC from other neuroendocrine neoplasms and NSCLC. Copyright © 2013 S. Karger AG, Basel.

To compare the Po(2) distribution in different regions in the eyes of patients undergoing intraocular surgery. Before initiation of intraocular cataract and/or glaucoma surgery, an optical oxygen sensor was introduced into the anterior chamber via a peripheral corneal paracentesis. The tip of the flexible fiberoptic probe was positioned by the surgeon for 3 measurements in all patients: (1) near the central corneal endothelium, (2) in the mid-anterior chamber, and (3) in the anterior chamber angle. In patients scheduled to undergo cataract extraction, Po(2) was also measured (4) at the anterior lens surface and (5) in the posterior chamber just behind the iris. Oxygen measurements at the 5 locations were compared using a 2-tailed unpaired t test and multivariate regression. The Po(2) value was significantly higher in African American patients at all 5 locations compared with Caucasian patients. Adjusting for age increased the significance of this association. Adjusting for race revealed that age was associated with increased Po(2) beneath the central cornea. Racial differences in oxygen levels in the human eye reflect an important difference in oxidative metabolism in the cornea and lens and may reflect differences in systemic physiologic function. Increased oxygen or oxygen metabolites may increase oxidative stress, cell damage, intraocular pressure, and the risk of developing glaucoma. Oxygen use by the cornea decreases with age.

[The clinical classification of acute otitis media with special reference to tympanometry].

PubMed

Subbotina, M V

We have developed a new clinical classification of acute otitis media (AOM) based on the previously proposed classifications of V.T. Palchun with co-workers (1997) and J. Jeger (1970) in which the letter near the stage of the pathological process roughly corresponds to the type of the tympanogram as follows: stage I (acute tubootitis): A, B, C; stage II (acute catarrhal otitis media): A, B, C; stage III (acute purulent otitis media, perforation stage); stage IV (acute purulent otitis media, post-perforation stage); stage V (resolution of otitis media): A - convalescence or recovery, B1 - exudate present in the tympanic cavity; B2 - persisting perforation; C - block of the auditory tube, O - the development of complications. This classification implies the necessity of tympanometry at the stage of diagnostics of AOM although it is not mandatory because the detection of exudate as a result of paracentesis at any of the stages of otitis media will allow to designate the stage of otitis either by letter A, B or C. The application of the new classification described in this article permits to more accurately than before determine the character of the pathological process in the middle ear during the course of acute otitis media which is of special importance in the clinical pediatric practice for the timely and adequate treatment of the children.

Live intraocular nematode is a rare occurrence that is mostly reported in Southeast Asian countries. Common nematodes that are seen live in the eye are microfilaria, Gnathostoma, and Angiostrongylus. Approximately 12 cases of intraocular gnathostomiasis have been reported in the literature. Two cases of intraocular gnathostoma, removed by vitrectomy in the first case and by paracentesis in the second case, are reported. Morphologic study of the parasites in wet preparation was performed under dissecting microscope and fixed in Karnovosky's fixative. Light microscopic and scanning electron microscopic studies were also performed. The first patient had anterior uveitis, multiple iris holes, and dense vitreous haze with fibrous proliferation over the optic disc. On resolution of the vitreous haze, a live worm was seen in the vitreous cavity. The second patient had anterior uveitis with secondary glaucoma, multiple iris holes, mild vitritis, and focal subretinal haemorrhage with subretinal tracts. Four days later a live worm was seen in the anterior chamber and removed. Microscopic study of the parasites from both patients revealed typical head bulb with four circumferential rows of hooklets, and fine cuticular spines were seen on the surface of the body. Iris holes, uveitis, and subretinal haemorrhage with subretinal tract can be characteristic features of intraocular gnathostomiasis. Identification of this parasite can be made by typical features, which can be identified on light and scanning electron microscopic study.

The rough estimation of the education and the self-confidence of nurses, both students and professionals, regarding deep venous catheterization in adult patients, the evaluation of the change in self-confidence of one team of students who were trained with a simulator on deep venous catheterization and the correlation of their self-confidence with their performance recorded by the simulator. Seventy-six nurses and one hundred twenty-four undergraduate students participated in the study. Fourty-four University students took part in a two-day educational seminar and were trained on subclavian and femoral vein paracentesis with a simulator and an anatomical model. Three questionnaires were filled in by the participants: one from nurses, one from students of Technological institutions, while the University students filled in the previous questionnaire before their attendance of the seminar, and another questionnaire after having attended it. Impressive results in improving the participants' self-confidence were recorded. However, the weak correlation of their self-confidence with the score automatically provided by the simulator after each user's training obligates us to be particularly cautious about the ability of the users to repeat the action successfully in a clinical environment. Educational courses and simulators are useful educational tools that are likely to shorten but in no case can efface the early phase of the learning curve in clinical setting, substituting the clinical training of inexperienced users.

The Demons-Meigs syndrome should usually be evoked in case of presence of a typical triad: abdominopelvic mass, ascites and hydrothorax. Its diagnosis appears crucial to prevent the realization of unnecessary surgical procedures. A 32-year-old woman presented in April 2012 to the emergency department of our maternity unit (General Hospital, Thiers, France) with an abdominal distension mimicking the symptoms of a pregnancy at term. Physical examination revealed a voluminous painful abdominopelvic mass, extended from the pelvis to the upper abdomen with a large right pleural effusion. Ultrasound and computed tomography showed it was a tumor measuring more than 300 mm in diameter with a right hydrothorax. Serum CA-125 level was 289 U/ml. Cytologic analysis of the pleural effusion didn't show any malignant cells. In this study, Demons-Meigs syndrome was recognized. A laparoscopico-laparotomic management permitted an aspiration of 23 liters of a brownish liquid and an unilateral adnexectomy after pleural paracentesis was performed. Frozen section demonstrated benign mucinous cystadenoma. The final histologic findings objectified intracystic intestinal type ovarian mucinous borderline tumor. After multidisciplinary consultation, the patient was re-operated one month later. The exploration didn't reveal any suspected lesions and appendectomy and omentectomy were performed. The postoperative course was uneventful. Serum CA-125 level was normal at the time of the reoperation and 24 months after the initial surgery. The preoperative recognition of a Demons-Meigs syndrome or a Demons' pseudosyndrome is essential to avoid useless surgical procedures.

Radiology Physician Extenders: A Literature Review of the History and Current Roles of Physician Extenders in Medical Imaging.

Sanders, Vicki L; Flanagan, Jennifer

2015-01-01

The purpose of the literature review was to assess the origins of radiology physician extenders and examine the current roles found in the literature of advanced practice physician extenders within medical imaging. Twenty-six articles relating to physician assistants (PAs), nurse practitioners (NPs), radiologist assistants (RAs), and nuclear medicine advanced associates (NMAAs) were reviewed to discern similarities and differences in history, scope of practice, and roles in the medical imaging field. The literature showed PAs and NPs are working mostly in interventional radiology. PAs, NPs, and RAs perform similar tasks in radiology, including history and physicals, evaluation and management, preprocedure work-up, obtaining informed consent, initial observations/reports, and post-procedure follow-up. NPs and PAs perform a variety of procedures but most commonly vascular access, paracentesis, and thoracentesis. RAs perform gastrointestinal, genitourinary, nonvascular invasive fluoroscopy procedures, and vascular access procedures. The review revealed NMAAs are working in an advanced role, but no specific performances of procedures was found in the literature, only suggested tasks and clinical competencies. PAs, NPs, and RAs are currently the three main midlevel providers used in medical imaging. These midlevel providers are being used in a variety of ways to increase the efficiency of the radiologist and provide diagnostic and therapeutic radiologic procedures to patients. NMAAs are being used in medical imaging but little literature is available on current roles in clinical practice. More research is needed to assess the exact procedures and duties being performed by these medical imaging physician extenders.

Many studies include elevated activity of angiotensin-converting enzyme (ACE) in serum in sarcoidosis and in ocular sarcoidosis as well, but there are only a few analyzing ACE activities in aqueous humor. The aim of this study is to illuminate the diagnostic value of ACE in aqueous humor in patients with ocular sarcoidosis. We analyzed twenty patients with ocular sarcoidosis and 18 patients with nonocular involvement. All patients have biopsy-positive sarcoidosis of the lungs and/or mediastinal lymph nodes. Blood samples for ACE serum levels were obtained from all patients. Aqueous humor samples were taken by paracentesis with a 25-gauge needle in local anesthesia. With appropriate statistical tests, we compared ACE activity in serum and aqueous humor in patients with and without ocular sarcoidosis. The majority of our patients with ocular sarcoidosis were female (12/20), also in the group with systemic sarcoidosis and without ocular involvement (12/6). Mean age of the whole analyzed group of sarcoidosis patients was 45 ± 6 years. There is no statistically significant difference in ACE activity in serum between two groups of patients (with and without ocular sarcoidosis). There is statistically significant difference in ACE activity in aqueous humor among patients with ocular and nonocular sarcoidosis. ACE activity in aqueous humor is significantly higher in patients with ocular sarcoidosis. Increased ACE activity in aqueous humor can point to a diagnosis of ocular sarcoidosis, without the need for ocular biopsy.

Invasive bedside procedures are core competencies for internal medicine, yet no formal training guidelines exist. The authors conducted a scoping review and realist synthesis to characterize current training for lumbar puncture, arthrocentesis, paracentesis, thoracentesis, and central venous catheterization. They aimed to collate how educators justify using specific interventions, establish which interventions have the best evidence, and offer directions for future research and training. The authors systematically searched Medline, Embase, the Cochrane Library, and ERIC through April 2015. Studies were screened in three phases; all reviews were performed independently and in duplicate. The authors extracted information on learner and patient demographics, study design and methodological quality, and details of training interventions and measured outcomes. A three-step realist synthesis was performed to synthesize findings on each study's context, mechanism, and outcome, and to identify a foundational training model. From an initial 6,671 studies, 149 studies were further reduced to 67 (45%) reporting sufficient information for realist synthesis. Analysis yielded four types of procedural skills training interventions. There was relative consistency across contexts and significant differences in mechanisms and outcomes across the four intervention types. The medical procedural service was identified as an adaptable foundational training model. The observed heterogeneity in procedural skills training implies that programs are not consistently developing residents who are competent in core procedures. The findings suggest that researchers in education and quality improvement will need to collaborate to design training that develops a "competent core" of proceduralists using simulation and clinical rotations.

To evaluate aqueous humor viscosity in the raptor, dog, cat, and horse, with a primary focus on the barred owl (Strix varia). Twenty-six raptors, ten dogs, three cats, and one horse. Animals were euthanized for reasons unrelated to this study. Immediately, after horizontal and vertical corneal dimensions were measured, and anterior chamber paracentesis was performed to quantify anterior chamber volume and obtain aqueous humor samples for viscosity analysis. Dynamic aqueous humor viscosity was measured using a dynamic shear rheometer (AR 1000 TA Instruments, New Castle, DE, USA) at 20 °C. Statistical analysis included descriptive statistics, unpaired t-tests, and Tukey's test to evaluate the mean ± standard deviation for corneal diameter, anterior chamber volume, and aqueous humor viscosity amongst groups and calculation of Spearman's coefficient for correlation analyses. The mean aqueous humor viscosity in the barred owl was 14.1 centipoise (cP) ± 9, cat 4.4 cP ± 0.2, and dog 2.9 cP ± 1.3. The aqueous humor viscosity for the horse was 1 cP. Of the animals evaluated in this study, the raptor aqueous humor was the most viscous. The aqueous humor of the barred owl is significantly more viscous than the dog (P < 0.0001). The aqueous humor viscosity of the raptor, dog, cat, and horse can be successfully determined using a dynamic shear rheometer. © 2014 American College of Veterinary Ophthalmologists.

Septoplasty is a commonly used procedure for correcting septal cartilage deformities. Hemorrhage, abscesses, scaling, adhesions, and scar tissue are often seen after the operation of the septoplasty, but temporary or permanent visual loss due to local anesthetic use has been reported very rarely in the literature. The authors also aimed to present a female patient with retinal artery spasm in the right eye after septoplasty in this article. A 27-year-old female patient was admitted to the authors' clinic with long-standing nasal obstruction and postnasal drip. There was no feature in her history and also no sign other than nasal septal deviation on physical examination. The patient was informed about the operation and the operation was planned. Emergency eye consultation was requested after the patient said that the right eye of the patient had never seen in the postoperative wake-up hall. Examination by an ophthalmologist; mild exotropia and total loss of vision in the right eye (including loss of light reflex) was detected. The light reaction in the affected eye was negative and indirect reaction was positive. After enlargement of the pupil, fundus examination revealed that the right posterior pole region (inside of the macula and vessel arches) was pale and no central retinal artery pulsation was observed. The patient was diagnosed with central retinal artery occlusion and emergency intervention was performed. The right eye massage, paracentesis, and hyperbaric oxygen therapy returned to the patient's visual function.

To compare aqueous humor concentrations of topically applied moxifloxacin 0.5% ophthalmic solution alone or in combination with dexamethasone 0.1% and to correlate these concentrations with the minimum inhibitory concentrations (MICs) for common endophthalmitis-causing organisms. Sixty-eight patients undergoing routine phacoemulsification with intraocular lens implantation received either moxifloxacin 0.5% alone or moxifloxacin 0.5% combined with dexamethasone. For both groups, 1 drop of the test solution was instilled 4 times daily 1 day preoperatively and 1 drop 1 h preoperatively. An aqueous humor sample obtained immediately before paracentesis was submitted to high-performance liquid chromatography-tandem mass spectrometry to determine the moxifloxacin concentration. The mean concentrations of moxifloxacin were 986.6 ng/mL in the moxifloxacin with dexamethasone group and 741.3 ng/mL in the moxifloxacin group (P = 0.13). Moxifloxacin concentrations of all samples exceeded the MICs for Staphylococcus epidermidis, S. aureus, and Streptococcus pneumoniae. All samples in the moxifloxacin with dexamethasone group and 94% in the moxifloxacin group achieved the MIC for Enterococcus species. For quinolone-resistant S. aureus, the MIC was achieved in 29% in the moxifloxacin with dexamethasone group and 9% in the moxifloxacin group (P = 0.06). Aqueous humor moxifloxacin concentrations were higher when topically administrated in combination with dexamethasone compared to the moxifloxacin alone. However, this difference was not statistically significant. Nevertheless, the MICs of the most common pathogens associated with endophthalmitis were exceeded in both study groups.

Purpose. To report one-year results of phacoemulsification combined with deep sclerectomy and goniosynechiolysis ab interno for chronic glaucoma associated with peripheral anterior synechiae (PAS). Methods. We retrospectively analyzed medical charts of 16 patients (20 eyes) treated by one-site combined phacoemulsification and deep sclerectomy with goniosynechiolysis ab interno. PAS were transected by a spatula introduced into the anterior chamber through a paracentesis. To account for the correlation of right and left eyes a linear mixed model with unstructured covariance structure was calculated. Results. The mean preoperative intraocular pressure (IOP) was 20.3 ± 5.2 mmHg with 2.4 ± 1.0 medications. One year postoperatively, the mean IOP was 15.3 ± 3.3 mmHg (P = 0.004, paired t-test) with 0.6 ± 1.0 medications. A postoperative IOP of ≤21 mmHg without medication was achieved in 17 of 19 eyes (89.5%) and in 12/19 eyes (63.2%) at 3 and 12 months after surgery, respectively. In the remaining eyes (10.5% at 3 months and 36.8% at 12 months), additional medication led to an IOP ≤21 mmHg or the target pressure. No case required further glaucoma surgery. In one eye, conversion of the surgery to trabeculectomy was necessary due to Descemet's window rupture. Conclusions. With goniosynechiolysis ab interno, effective and safe nonpenetrating glaucoma surgery is possible in presence of PAS. PMID:26199738

Malignant ascites (MA) is one of the poor prognostic factors for advanced pancreatic cancer and can bring about serious symptoms. The improvement of quality of life for patients is priority. However, there is no standard method for the treatment for pancreatic cancer-mediated MA. Apatinib is a novel and highly selective tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2. There are no reports of concurrent apatinib with gemcitabine in patients with pancreatic cancer-mediated MA. Herein, we presented a 64-year-old man patient who visited hospital due to abdominal pain for 1 month. He was initially diagnosed with pancreatic cancer and his first symptom was MA. After failing in tube drainage and gemcitabine therapy, the patient received gemcitabine combined apatinib orally and after administrated 1 month, the MA was evaluated as nearly clear response according to the RECIST 1.1 standard, and without further need of paracentesis. The CEA and CA199 reached the lowest level after administrating for 2.5 months during the treatment process. 10.5 months following apatinib administration, the patient achieved a progression-free survival for more than 11 months. Hypertension (grade IV), hand-foot syndrome (grade I) and proteinuria (grade II) were observed. It indicated that apatinib concurrent gemcitabine may be a superior choice for pancreatic cancer-mediated MA. Further clinical trials required to confirm its efficacy and safety.

Spontaneous bacterial peritonitis (SBP) as a monomicrobial infection of ascites fluid is one of the most important causes of morbidity and mortality in cirrhotic patients. This study was aimed to determine the diagnostic accuracy of ascites fluid color in detection of SBP in cirrhotic cases referred to the emergency department. Cirrhotic patients referred to the ED for the paracentesis of ascites fluid were enrolled. For all studied patients, the results of laboratory analysis and gross appearance of ascites fluid registered and reviewed by two emergency medicine specialists. The sensitivity, specificity, positive and negative predictive value, and positive and negative likelihood ration of the ascites fluid gross appearance in detection of SBP were measured with 95% confidence interval. The present project was performed in 80 cirrhotic patients with ascites (52.5 female). The mean of the subjects' age was 56.25±12.21 years (35-81). Laboratory findings revealed SBP in 23 (29%) cases. Fifty nine (73%) cases had transparent ascites fluid appearance of whom 17 (29%) ones suffered from SBP. From 21 (26%) cases with opaque ascites appearance, 15 (71%) had SBP. The sensitivity and specificity of the ascites fluid appearance in detection of SBP were 46.88% (Cl: 30.87-63.55) and 87.50% (95% Cl: 75.3-94.14), respectively. It seems that the gross appearance of ascites fluid had poor diagnostic accuracy in detection of SBP and considering its low sensitivity, it could not be used as a good screening tool for this propose.

Sildenafil citrate increases ocular blood flow and accelerates the rate of anterior chamber refilling after paracentesis. The latter effect could have resulted from a reduction in outflow facility or from an increase in aqueous humor (AH) production. In this study, we used scanning ocular fluorophotometry to examine the effects of sildenafil on AH turnover, and thus, AH production in eyes of live normal rabbits. For this, the rate of aqueous humor flow (AHF) was quantified with a commercially available fluorophotometer that measured the rate of fluorescein clearance from the anterior segment, which predominantly occurs via the trabecular meshwork. After ≈ 2 hrs of control scans to determine the baseline rate of AHF, the rabbits were fed 33 mg of sildenafil and allowed ≈ 45 min for the drug to enter the systemic circulation. Thereafter, fluorescence scans were retaken for an additional 90–120 min. Sildenafil ingestion increased AHF by about 36%, from 2.31 μL/min to 3.14 μL/min (P< 0.001, as two-tailed paired data, n= 20 eyes). This observation indicates that sildenafil citrate, which is a phosphodiesterase type-5 inhibitor currently marketed as a vasodilator (e.g., Viagra, Revatio), stimulates AHF in rabbits. Our results seem consistent with reports indicating that the drug dilates intraocular arteries and augments intraocular vascular flow. These physiological responses to the agent apparently led to increased fluid entry into the anterior chamber. As such, the drug might have utility in patients with ocular hypotony resulting from insufficient AH formation. PMID:23562660

To report the case of a young boy, homozygous for the hemoglobin S, who presented a pseudouveitis in the setting of severe sickle cell retinopathy complicated by macular infarction. Case report. A 15 year-old boy with a history of hypertensive uveitis of two months duration was reffered to our institution. He was treated with topical prednisolone acetate, beta-blockers and acetazolamide.The visual acuity was 20/200 RE and 20/25 LE. Anterior inflammation included fine inferior keratic precipitates with 2+ cells RE and 1+ cells LE. Vitreous haze was 2+ preventing clear view of subretinal infiltrates scattered around the posterior pole and midperipheral retina, some of them having a salmon patch appearance. Fluorescein angiograms revealed multiple preretinal haemorrahge and some areas of retinal ischemia. Fundus examination of the left eye was normal. A diagnosis of panuveitis was done and a sickle cell retinopathy was suspected. Systemic workup showed an hemoglobin at 8,2 mg/dl and sickle cells on direct examination. Two days later he developed sudden loss of vision in the right eye. Funduscopy an angiogram revealed macular infarction with occlusion of the retinal arterioles surrounding the foveal avascular zone. The clinical picture was not improved by erythrocyte transfusion. Intraocular pressure raised again after few days, and was finally controlled by anterior chamber paracentesis. The patient was later found to be homozygous for HbS. Sickle cell retinopathy can rarely masquerade as panuveitis, and can lead to severe ocular complications as an irreversible macular ischemia.

Rifaximin is a non-absorbable antibiotic used to prevent relapses of hepatic encephalopathy which may also be a candidate for prophylaxis of spontaneous bacterial peritonitis (SBP). To detect the impact of rifaximin on the occurrence and characteristics of SBP. We prospectively studied all hospitalized patients that underwent a diagnostic paracentesis in our department from March 2012 to April 2013 for SBP and recorded all clinical data including type of SBP prophylaxis, prior use of rifaximin, concomitant complications of cirrhosis, as well as laboratory results and bacteriological findings. Patients were divided into the following three groups: no antibiotic prophylaxis, prophylaxis with rifaximin or with systemically absorbed antibiotic prophylaxis. Our study cohort comprised 152 patients with advanced liver cirrhosis, 32 of whom developed SBP during the study period. As expected, our study groups differed regarding a history of hepatic encephalopathy and SBP before inclusion into the study. None of the 17 patients on systemic antibiotic prophylaxis developed SBP while 8/27 patients on rifaximin and 24/108 without prophylaxis had SBP (p = 0.02 and p = 0.04 versus systemic antibiotics, respectively). In general, episodes of SBP were similar for patients treated with rifaximin and those without any prophylaxis. However, Escherichia coli and enterococci were dominant in the ascites of patients without any prophylaxis, while mostly klebsiella species were recovered from the ascites samples in the rifaximin group. Rifaximin pretreatment did not lead to a reduction of SBP occurrence in hospitalized patients with advanced liver disease. However, the bacterial species causing SBP were changed by rifaximin.

Management of refractory ascites traditionally includes medical treatment with diuretics or intermittent paracentesis. Patients with recurrent ascites may benefit from the use of permanent intra-abdominal catheters with more frequent drainage without hospitalization. The objective was to systematically asses the methodology of factors and endpoints reported in studies investigating permanent catheters for recurrent ascites treatment. Using a systematic search strategy, we critically assessed the methodology when treating refractory ascites using a permanent catheter. Studies critically assessed included both retro- and prospective studies. A total of 715 unique articles were found via PubMed, The Cochrane Library and Embase. Twenty-nine studies (tunnelled catheter = 12, peritoneal ports = 6 and peritoneovenous shunts = 11) with three distinct types of permanent catheters fulfilled the inclusion criteria. Only three studies reported technical success less than 100 %. Data on complications and treatment were not available in all papers; peritonitis (48 %), cellulitis (41 %), prophylactic antibiotics (48 %) and complications to catheter insertion were difficult to distinguish from advanced co-morbidity of patients. Thirteen studies (45 %) reported some type of evaluating patient experience or functional outcome, but only three studies used validated reproducible scales when assessing outcomes. Fifteen of the 29 studies included 30 patients or less. Knowledge is limited because complications and outcomes are poorly defined. The expected increase in catheter treatment of refractory ascites necessitates comparative studies, using validated patient-related outcomes, and the reporting of unambiguous complications. A proposal of variables to include in future studies is presented.

Methotrexate is a dihydrofolate reductase enzyme inhibitor with very high selectivity, and it is an antiproliferative folic acid antagonist used for the treatment of autoimmune diseases. In this study, our objective was to evaluate the effect of intratympanic Methotrexate application in the inner ear. This study was planned as an animal study. This study performed in a tertiary referral center. 24 healthy female rats were used in our study. They were separated into three groups. 0.2 cc intratympanic saline was applied to both ears of Group 1. Paracentesis was applied to the tympanic membrane in both ears of Group 2. 0.2 cc intratympanic Methotrexate was applied to both ears of Group 3. At the beginning of the study, Distortion-product otoacoustic emissions (DPOAE) and Auditory brainstem response (ABR) of all rats were measured and then again on the 5th, 10th and 15th day. Histologic examinations of all groups were compared. There was not any significant difference between basal DPOAE and ABR measurement values of the groups and the results were measured again on the 5th, 10th and 15th day (p > 0.05). There was no difference between the groups in terms of histology. The intratympanic Methotrexate injection does not have any ototoxic effect on inner ear. We assume that intratympanic Methotrexate could be used safely on inner ear diseases in which steroid treatment is contraindicated or not effective. Copyright © 2017 Elsevier B.V.

Recipients of liver transplant are surviving longer as both the surgical procedure and postsurgical care have improved. Despite improvements, serious complications from the procedure remain that significantly affect patient outcome and may result in retransplant. Refractory ascites is one complication, occurring in about 5.6% of transplant recipients. Management of refractory ascites after liver transplant presents a challenge to the multidisciplinary team caring for these patients. We discuss approaches to the diagnosis and treatment of refractory ascites after liver transplant, based on a literature review, with a primary focus on vascular causes. These approaches are illustrated by case examples highlighting our experiences at an academic tertiary medical center. We propose a clinical practice algorithm for optimal endovascular treatment of refractory ascites after liver transplant. The cornerstone of refractory ascites care is diagnosis and treatment of the cause. Vascular causes are not infrequently encountered and, if not treated early, are associated with graft loss and high morbidity and mortality and are major indications for retransplant. For patients with recurrent disease or graft rejection needing large volume paracentesis, the use of a transjugular intrahepatic portosystemic shunt may serve as a bridge to more definitive treatment (retransplant), although it may not be as effective for managing ascites as splenic artery embolization, arguably underused, which is emerging as a potential alternative treatment option. A multidisciplinary strategy for the diagnosis and care of patients with refractory ascites after liver transplant is crucial, with endovascular treatment playing an important role. The aim is for this document to serve as a concise and informative reference to be used by those who may care for patients with this rare yet serious diagnosis.

Previous studies have shown the presence of diadenosine tetraphosphate (Ap(4)A) and pentaphosphate (Ap(5)A) in the aqueous humour (AH) of different species. When topically applied to the rabbit cornea, Ap(4)A decreased IOP while Ap(5)A increased it. Here we study the presence of dinucleoside polyphosphates in the AH from human patients with or without glaucoma. AH was obtained at the time of cataract surgery from patients with (n=16) or without (n=10) primary open-angle glaucoma. AH (0.1-0.2 ml) was collected at the beginning of surgery through a corneal paracentesis and immediately cooled in liquid nitrogen, kept frozen and protected from light. AH aliquots were analyzed by HPLC for the presence of Ap(4)A and Ap(5)A. Both, Ap(4)A and Ap(5)A were detected in the AH of both experimental groups. No significant differences were found for Ap(5)A. In contrast, Ap(4)A levels were increased by ∼15-fold in the AH from glaucomatous eyes ranging from 19.5±9.2 nM in normal individuals to 286.03±30.9 nM in glaucomatous patients. In conclusion, both Ap(4)A and Ap(5)A were detected for the first time in human AH. Interestingly, glaucomatous eyes presented elevated concentrations of Ap(4)A compared to controls. The role of Ap(4)A needs to be elucidated but it may help to protect the autonomic innervation in the ciliary body/trabecular meshwork. Also, because of its higher levels in glaucoma patients it may be considered as a possible glaucoma biomarker. Copyright © 2010 Elsevier Ltd. All rights reserved.

Glaucoma is an optic neuropathy characterized by a high intraocular pressure (IOP), alterations in optic nerve head, and loss of visual field that could lead to bilateral blindness. Serotonin (5-HT) is a biogenic monoamine that is synthesized from hydroxylation of tryptophan and acts by three ways, dissemination, metabolism, and reuptake in synaptic cleft through specific systems of the membrane. The purpose of this study is to evaluate the 5-HT and 5-HIAA (5-hydroxiindolacetic acid) levels in the aqueous humor of patients with primary open-angle glaucoma (POAG). We performed a case-control study, and the patients recruited were classified into two groups, 1) 30 patients with POAG (GG) and 2) 30 patients with cataracts (CG), who acted as the controls. Aqueous humor samples of each patient were obtained by paracentesis at the beginning of the surgical procedures. 5-HT and 5-HIAA levels were determined by high performance liquid chromatography (HPLC) with electrochemical detection. There were no statistical differences between age (71.3 +/- 7.2 years in GG, 73.5 +/- 9.0 years in CG; p=0.2581) or gender (sex ratio 0.765 in GG and 0.667 in CG). 5-HT levels were lower in GG, but this difference was not significant (p=0.820). We observed a statistically significant higher level of 5-HIAA in GG (p=0.001). The 5-HT turnover (5-HIAA/5-HT) were higher in GG than in CG (p<0.05), but the difference was not significant (p=0.598). The level of 5-HT was lower in GG patients, and the level of 5-HIAA was higher in GG patients than in CG patients.

To make the reader familiar with the term evidence based medicine (EBM), to explain the principle of cost-effectiveness analysis (price-profit), and to show its usefulness to compare the effectiveness of different medical procedures. Based on few examples, in this article the relevance and calculation of important parameters of cost-effectiveness analysis (CE), as utility value (UV), quality adjusted life years (QALY) is explained. In addition, calculation of UV and QALY for the cataract surgery, including its complications, is provided. According to this method, laser photocoagulation and cryocoagulation of the early stages of retinopathy of prematurity, treatment of amblyopia, cataract surgery of one or both eyes, from the vitreoretinal procedures the early vitrectomy in cases of hemophtalmus in proliferative diabetic retinopathy or grid laser photocoagulation in diabetic macular edema or worsening of the visual acuity due to the branch retinal vein occlusion belong to highly effective procedures. On the other hand, to the procedures with low cost effectiveness belongs the treating of the central retinal artery occlusion with anterior chamber paracentesis, as well as with CO2 inhalation, or photodynamic therapy in choroidal neovascularization in age-related macular degeneration with visual acuity of the better eye 20/200. Cost-effectiveness analysis is a new perspective method evaluating successfulness of medical procedure comparing the final effect with the financial costs. In evaluation of effectiveness of individual procedures, three main aspects are considered: subjective feeling of influence of the disease on the patient's life, objective results of clinical examination and financial costs of the procedure. According to this method, the cataract surgery, as well as procedures in the pediatric ophthalmology belong to the most effective surgical methods.

To describe intravitreal injection (IVI) techniques and treatment protocols by retina specialists in Canada from August 1, 2012, to October 1, 2012. Cross-sectional survey. All fellowship-trained retina specialists across Canada, as identified from the Canadian Ophthalmological Society directory and the Canadian Retina and Vitreous Society directory. An anonymous 28-question survey was sent to 125 retina specialists across Canada by email. Reminder letters were sent by email, mail, and fax as necessary. A total of 75 (63%) retina specialists responded to the survey. Most IVIs were performed in the office. Most surgeons did not use gloves (61%), sterile draping (91%), or surgical mask (71%). Antisepsis was used on conjunctiva by 100% and on periocular skin by 48%. Nearly all specialists used a sterile lid speculum (91%). Common anaesthetics included topical proparacaine or lidocaine drops (90%), topical lidocaine gel (25%), topical pledget (23%), and subconjunctival lidocaine injections (23%). Most (83%) dilate the pupil before IVI. Prophylactic topical antibiotics were used by 43%; 50% of these were started immediately after IVI. Injection location was estimated by visualization by 45%. A majority (63%) inject inferotemporally. Anterior chamber paracentesis was performed routinely by 5%. Optic nerve perfusion was formally assessed by 48%. The most common treatment protocol for age-related macular degeneration was treat and extend. For both diabetic and retinal vein occlusion-related macular edema, the most common protocol was 3 initial monthly injections with PRN follow-up. A wide variety of IVI practice patterns exist in terms of aseptic technique, anaesthetics, prophylactic antibiotics, postinjection monitoring, and treatment protocol.

[Channelography and mechanism of action in canaloplasty].

PubMed

Grieshaber, M C

Canaloplasty lowers the intraocular pressure (IOP) by restoring the natural outflow system. The success of canaloplasty depends on the function of this system. To evaluate the natural outflow system regarding canaloplasty by two clinical tests, provocative gonioscopy and channelography and to describe the mechanism of action of canaloplasty. Provocative gonioscopy evaluates the pattern of blood reflux which is induced by ocular hypotension as the result of a reversed pressure gradient between the episcleral venous pressure and IOP following paracentesis. In channelography the transtrabecular diffusion and the filling properties of the episcleral venous system are assessed by a microcatheter and a fluorescein tracer. Blood reflux varied greatly in glaucomatous eyes and showed an inverse correlation with the preoperative IOP. The higher the IOP, the poorer the blood reflux. The filling qualities of the episcleral venous system and diffusion through the trabecular meshwork were different. Poor trabecular passage and good episcleral fluorescein outflow indicates patent distal outflow pathways, poor trabecular passage and poor episcleral fluorescein outflow indicates obstructed trabecular meshwork and closed collector channels and good trabecular passage together with poor episcleral fluorescein outflow suggests that the site of impairment is mainly in the distal outflow system. The quality of blood reflux and the characteristics of the episcleral filling and the transtrabecular diffusion by fluorescein represent the clinical state of the outflow pathway and help in the prediction of the surgical outcome in canaloplasty. The mechanism for canaloplasty is not yet completely clarified; currently under discussion are circumferential viscodilation, permanent distension of the inner wall of Schlemm's canal using a suture and a Stegmann canal expander.

To describe a technique of surgical peripheral iridectomy via a clear-cornea tunnel incision to prevent or treat pupillary block following phacoemulsification. Description of technique and retrospective description results in 20 eyes of 20 patients with acute angle closure with coexisting visually significant cataract undergoing phacoemulsification considered at risk of postoperative papillary block as well as two pseudo-phakic eyes with acute postoperative pupillary-block. Following phacoemulsification and insertion of an intraocular lens, a needle with a bent tip was inserted behind the iris through the corneal tunnel incision. A blunt iris repositor was introduced through the paracentesis and placed above the iris to exert posterior pressure and create a puncture. The size of the puncture was enlarged using scissors. For postoperative pupillary block the same technique was carried out through the existing incisions created for phacoemulsification. Peripheral iridectomy was successfully created in all 22 eyes. At a mean follow-up of 18.77 ± 9.72 months, none of the iridectomies closed or required enlargement. Two eyes had mild intraoperative bleeding and one eye a small Descemet's detachment that did not require intervention. No clinically significant complications were observed. Visual acuity and IOP improved or was maintained in all patients. The incidence of pupillary block in our hospital was 0.09% overall, 0.6% in diabetics and 3.5% in those with diabetic retinopathy. This technique of peripheral iridectomy via the cornea tunnel incision can be safely used during phacoemulsification in eyes at high risk of pupillary block or in the treatment of acute postoperative pupillary-block after cataract surgery. The technique is likely to be especially useful in brown iris, or if a laser is not available.

Ascites leaks (AL) in patients with end-stage liver disease (ESLD) are associated with significant morbidity and mortality regardless if they are medically or surgically managed. In a pilot study, 14 ESLD patients with AL underwent treatment with fibrin glue injection around the leak after failing conservative therapy. The end point of this study was the cessation of AL in the short term and the maintenance of a leak-free abdomen in the long term, allowing for medical optimization of the patients. Median age of the 10 men and 4 women was 50 (range 26-67) years. Underlying ESLDs were chronic hepatitis C (n=5), alcoholic LD (n=2), cryptogenic cirrhosis (n=2), and miscellaneous (n=5). There were six leaking incisions posthernia repair (three umbilical and three inguinal), two leaking/ruptured umbilical hernias, four leaking paracentesis sites, one leaking Jackson-Pratt (JP) drain canal, and one leaking laparoscopic trocar site. Average AL volume per day was 1000 (range 400-2000) mL. All leaks were immediately resolved with a 3-5 mL fibrin glue injection. Five recurred and required a second injection (four within 24 hours). Mental status improved in 7 patients (West Haven Criteria: grade II to I [n=6], grade III to I [n=1]). Median model of end-stage liver disease scores improved from 23 (range 8-33) to 20 (range 14-26). There were no infections, bleeds, or other injection-related complications. Average follow-up for these patients was 441.6 days (range 2-852). Five patients underwent liver transplant (LT) median 15 (range 4-270) days postinjection; 2 of them died. Another 3 patients died (2 from sepsis and 1 from metastatic cancer). Fibrin glue injection for the control of AL is a simple and safe bedside procedure that quickly controls AL, allowing for patient recovery in anticipation of further care.

To determine the pattern, presentation and outcome of gastrointestinal injuries from blunt abdominal trauma in children. A retrospective study. Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. Twenty one children managed for gastrointestinal injuries from blunt trauma from 1984-2002. The pattern, presentation, management and outcome of gastrointestinal injuries from blunt trauma. In the 19 year period, 1984-2002, 92 children were treated for blunt abdominal trauma, 21(23%) of who had injuries to the gastrointestinal tract. Three presenting after 24 hours had evidence of peritonitis. In six children with isolated gastrointestinal tract (GIT) injury who presented within two hours, abdominal signs were vague at initial evaluation but became marked over a few hours at repeated examination. In eight with associated intraabdominal injuries, abdominal signs were marked at initial examination and five presented with shock. Free peritoneal air was present on plain abdominal and chest radiograph in three of ten patients, dilated bowel loops in six and fluid levels in one. Diagnostic peritoneal lavage or paracentesis was positive in four patients with isolated GIT injuries and eight with associated intraabdominal injuries. There were 24 injuries in the 21 patients consisting of 15 perforations, five contusions, two seromuscular tears, and two gangrene from mesenteric injury. The small intestine was involved in 11 patients, colon six, stomach five, duodenum one and rectum one. Seven (35%) patients had associated extraabdominal injuries. Treatment consisted of simple closure of perforations, over sewing of contusions, resection and anastomosis for gangrene and repair with protective stoma for the rectal injury. One patient each developed prolonged ileus, urinary tract infection and chest infection, respectively postoperatively. Mortality was 28%, all of who had associated intraabdominal or extraabdominal injuries. Gastrointestinal injury from blunt abdominal trauma in

At some academic hospitals, medical procedure services are being developed to provide supervision for residents performing bedside procedures in hopes of improving patient safety and resident education. There is limited knowledge of the impact of such services on procedural complication rates and resident procedural training opportunities. To determine the impact of a medical procedure service (MPS) on patient safety and resident procedural training opportunities. Retrospective cohort analysis comparing characteristics and outcomes of procedures performed by the MPS versus the primary medical service. Consecutive adults admitted to internal medicine services at a large academic hospital who underwent a bedside medical procedure (central venous catheterization, thoracentesis, paracentesis, lumbar puncture) between 1 July 2010 and 31 December 2011. The primary outcome was a composite rate of major complications. Secondary outcomes included resident participation in bedside procedures and use of "best practice" safety process measures. We evaluated 1,707 bedside procedures (548 by the MPS, 1,159 by the primary services). There were no differences in the composite rate of major complications (1.6 % vs. 1.9 %, p = 0.71) or resident participation in bedside procedures (57.0 % vs. 54.3 %, p = 0.31) between the MPS and the primary services. Procedures performed by the MPS were more likely to be successfully completed (95.8 % vs. 92.8 %, p = 0.02) and to use best practice safety process measures, including use of ultrasound guidance when appropriate (96.8 % vs. 90.0 %, p = 0.0004), avoidance of femoral venous catheterization (89.5 vs. 82.7 %, p = 0.02) and involvement of attending physicians (99.3 % vs. 57.0 %, p < 0.0001). Although use of a MPS did not significantly affect the rate of major complications or resident opportunities for training in bedside procedures, it was associated with increased use of best practice safety process measures.

Use of a "small-bubble technique" to increase the success of Anwar's "big-bubble technique" for deep lamellar keratoplasty with complete baring of Descemet's membrane.

To describe a quick and simple "small-bubble" technique to immediately determine the success of attaining complete Descemet's membrane (DM) separation from corneal stroma through Anwar's "big-bubble" technique of deep anterior lamellar keratoplasty (DALK) for complete stromal removal. A partial trephination was followed by a lamellar dissection of the anterior stroma. Deep stromal air injection was then attempted to achieve the big bubble to help separate the stroma from the DM. To confirm that a big bubble had been achieved, a small air bubble was injected into the anterior chamber (AC) through a limbal paracentesis. If the small bubble is then seen at the corneal periphery, it confirms that the big-bubble separation of DM was successful because the convex nature of the bubble will cause it to protrude posteriorly, forcing the small AC bubble to the periphery. If the small AC bubble is not seen in the corneal periphery, this means that it is present in the centre, beneath the opaque corneal stroma, and therefore the big bubble has not been achieved. We used the small-bubble technique to confirm the presence of the big bubble in three (one keratoconus, one interstitial keratitis and one dense corneal scar) out of 41 patients who underwent DALK. The small-bubble technique confirmed that the big bubble was achieved in the eye of all three patients. Complete stromal removal with baring of the DM was achieved, and postoperatively all three eyes achieved best corrected vision of 6/6. The small-bubble technique can be a useful surgical tool for corneal surgeons attempting lamellar keratoplasty using the big-bubble technique. It helps in confirming the separation of DM from the deep stroma, which is important in achieving total stromal replacement. It will help to make the transition to lamellar keratoplasty smoother, enhance corneal graft success and improve visual outcomes in patients.

Clinical training in most medical schools, including the Catholic University of Health and Allied Sciences (CUHAS), is offered in the form of junior and senior rotations. During these clinical rotations, students are expected to acquire and master the basic procedural skills. However, students' learning process should be evaluated for quality improvement. This study was conducted to identify the basic medical procedural skills that third-year medical students should acquire and master and determine the level of students' exposure on these procedures at the end of junior rotation in internal medicine. Identification of the gap between clinicians' opinions, skills practiced by students, and third-year students' curriculum in the medical department at CUHAS was also done. The descriptive cross-sectional study was used to collect data through a self-administered, structured questionnaire from clinicians in medicine. A review of logbooks was considered to determine level of students' exposure, and a document analysis was done using existing medical curriculum. The response of 71% (n=22) was obtained. Clinicians agreed on basic procedures that students should perform independently (ie, Foley catheter insertion, venipuncture, and intravenous drip insertion). Clinicians thought that lumbar punctures, abdominal paracentesis, and nasogastric tube insertion should be done under minimal supervision. A considerable number of students (25%, n=75) did not practice any procedure throughout their rotation. The majority of the students performed venipuncture independently (82.14%, n=56) and lumbar punctures (73.21%, n=56) under supervision. Less than 25% (n=56) of the students met the required number of exposures on the basic procedures. The procedures to be performed and the level of competency in the procedures are not specified in the current curriculum. The study identified the procedures that should be taught and practiced by students. It also highlighted the discrepancies in

Infections in patients affected by liver cirrhosis: an update.

PubMed

Ascione, Tiziana; Di Flumeri, Giusy; Boccia, Giovanni; De Caro, Francesco

2017-06-01

Patients with liver cirrhosis present an increased incidence of infections. The main cause has been founded in alterations of the enteric flora and of the intestinal barrier probably due to portal hypertension, in addition to a reticulo-endothelial system dysfunction. Furthermore, those living with cirrhosis can report a high predisposition to sepsis and septic shock, due to the excessive response of pro-inflammatory cytokines and a complessive hemodynamic derangement. By the analysis in the experimental model of the cirrhotic rat, it was demonstrated that radio-labelled Escherichia coli given by the oral route resulted in the location of the bacteria in the gut, the ascitic fluid and mesenteric lymph nodes, a phenomenon known as bacterial translocation. Bacteria encountered with the highest frequency are those colonizing the intestinal tract, such as E. coli, Klebsiella pneumoniae and Enterobacteriaceae, intracellular bacteria and parasites are reported with a lower frequency. Multi-drug resistant bacteria are cultured with the highest frequency in those with frequent hospitalisations and report both high septic shock and mortality rates. Spontaneous bacterial peritonitis (SBP) is the commonest infection in cirrhotic, estimated to occur in 10-30% of the cases with ascites. A practical approach may include administration of a protected penicillin, III generation cephalosporin or quinolones in uncomplicated cases. Instead, in complicated cases and in nosocomial SBP, administration of cephalosporin or quinolones can be burned by the high resistance rate and drugs active against ESBL-producing bacteria and multi-drug resistant Gram positive bacteria have to be considered as empiric therapy, until cultures are available. When cultures are not readily available and patients fail to improve a repeated diagnostic paracentesis should be performed. Current investigations suggest that norfloxacin 400 mg/day orally has been reported to successfully prevent SBP in patients

The Japanese Society of Gastroenterology revised the evidence-based clinical practice guidelines for liver cirrhosis in 2015. Eighty-three clinical questions were selected, and a literature search was performed for the clinical questions with use of the MEDLINE, Cochrane, and Igaku Chuo Zasshi databases for the period between 1983 and June 2012. Manual searching of the latest important literature was added until August 2015. The guidelines were developed with use of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. This digest version in English introduces selected clinical questions and statements related to the management of liver cirrhosis and its complications. Branched-chain amino acids relieve hypoalbuminemia and hepatic encephalopathy and improve quality of life. Nucleoside analogues and peginterferon plus ribavirin combination therapy improve the prognosis of patients with hepatitis B virus related liver cirrhosis and hepatitis C related compensated liver cirrhosis, respectively, although the latter therapy may be replaced by direct-acting antivirals. For liver cirrhosis caused by primary biliary cirrhosis and active autoimmune hepatitis, urosodeoxycholic acid and steroid are recommended, respectively. The most adequate modalities for the management of variceal bleeding are the endoscopic injection sclerotherapy for esophageal varices and the balloon-occluded retrograde transvenous obliteration following endoscopic obturation with cyanoacrylate for gastric varices. Beta-blockers are useful for primary prophylaxis of esophageal variceal bleeding. The V2 receptor antagonist tolvaptan is a useful add-on therapy in careful diuretic therapy for ascites. Albumin infusion is useful for the prevention of paracentesis-induced circulatory disturbance and renal failure. In addition to disaccharides, the nonabsorbable antibiotic rifaximin is useful for the management of encephalopathy. Anticoagulation therapy is proposed for

Ascites Neutrophil Gelatinase-Associated Lipocalin Identifies Spontaneous Bacterial Peritonitis and Predicts Mortality in Hospitalized Patients with Cirrhosis.

Neutrophil gelatinase-associated lipocalin (NGAL) is a marker of both tissue injury and infection. Urine NGAL levels strongly predict acute kidney injury and mortality in patients with cirrhosis, but ascites NGAL is not well characterized. We hypothesized that ascites NGAL level is a marker of spontaneous bacterial peritonitis (SBP) and mortality risk in patients with cirrhosis. Hospitalized patients with cirrhosis and ascites undergoing diagnostic paracentesis were prospectively enrolled and followed until death or discharge. Patients with secondary peritonitis, prior transplantation, or active colitis were excluded. NGAL was measured in the ascites and serum. Ascites NGAL level was evaluated as a marker of SBP (defined as ascites absolute neutrophil count > 250 cells/mm 3 ) and predictor of in-patient mortality. A total of 146 patients were enrolled, and of these, 29 patients (20%) had SBP. Baseline characteristics were similar between subjects with and without SBP. Median (IQR) ascites NGAL was significantly higher in patients with SBP compared to those without SBP (221.3 [145.9-392.9] vs. 139.2 [73.9-237.2], p < 0.01). Sixteen (11%) patients died in the hospital. In the final multivariable model, ascites NGAL (OR 1.02 per 10 units, p < 0.01) remained predictive of in-hospital mortality, controlling for SBP (OR 9.76, p < 0.01) and MELD (OR 1.11, p = 0.01). In ROC analysis, ascites NGAL had an AUC of 0.79 for inhospital mortality, and the final model including ascites NGAL, MELD, and SBP had an AUC of 0.94. Ascites NGAL level may be a biomarker of peritonitis in hospitalized patient with cirrhosis and an independent predictor of short-term in-hospital mortality, even controlling for SBP and MELD.

To measure aqueous humor levels of TGF-β2 and TNF-α in Indonesian eyes with acute primary angle closure (APAC) and to investigate their relationship to response to treatment. A prospective observational study. On presentation, aqueous humor samples were taken from APAC eyes by paracentesis. All APAC eyes then underwent laser peripheral iridotomy (LPI). Two weeks following LPI, trabeculectomy was performed if the intraocular pressure (IOP) was still high. Alternatively, phacoemulsification was performed in cases of normal IOP. Aqueous humor samples were taken again at the time of both surgical procedures. Age-matched cataract patients were included as a control group. Cytokine samples were measured by enzyme-linked immunosorbent assay (ELISA). Forty-three Indonesian APAC subjects were recruited in this study. The mean presenting IOP was 56.4 ± 0.52 mmHg and 53% underwent trabeculectomy. Comparison of the APAC eyes to the control group showed there was a significant difference in the mean levels of TGF-β2 (2007.7 ± 827.2 pg/mL vs 466.1 ± 219.3 pg/mL, p < 0.001) and TNF-α (0.714 ± 0.33 pg/mL vs 0.228 ± 0.16 pg/mL, p < 0.001). There was no significant difference in the presented TGF-β2 and TNF-α levels between the trabeculectomy and phacoemulsification groups (p:0.391 and p:0.494). Between presentation and surgery in the trabeculectomy subgroup, both cytokine levels appeared to be significantly different (p < 0.035 and p < 0.038). This study showed the aqueous humor levels of TGF-β2 and TNF-α appeared high at presentation but decreased subsequently, with no difference detected between groups with persistently high IOP and those with normalized IOP.

The occurrence of refractory ascites in nearly 17% of patients with decompensated cirrhosis is an unresolved issue. Advanced liver disease, functional renal impairment, and vascular insensitivity to vasopressors are the main causes of its refractoriness. Therefore, the aim of this study was to evaluate the impact on diuresis, weight loss, and short-term survival if midodrine and rifaximin were added to the diuretic therapy (DT). The study evaluated the eligibility of 650 patients with cirrhosis and refractory ascites who were selected during the period from November 2011 to May 2015. A total of 50 patients were excluded and finally 600 were selected and divided into the following groups: patients exposed to DT (n=200) as a control group, or DT with midodrine and rifaximin group (n=400). Body weight, mean arterial pressure, and glomerular filtration rate were determined. Plasma renin and aldosterone were also determined. Follow-up was performed after 2, 6, and 12 weeks, and then every 2 months for 24 months. The mean arterial pressure was significantly higher in the midodrine and rifaximin group (P=0.000), and there was a highly significant weight loss after 12 weeks (12.5 kg) (P=0.000), a highly significant increase in serum sodium, urine output, and urinary sodium excretion (P=0.000), and creatinine clearance was more reduced in the control group. With rifaximin and midodrine, a complete response occurred in 310 (78%) patients, a partial response in 72 (18%), and no response in 18 (4%) versus 30 (15%), 110 (55%), and 60 (30%) in the control group, respectively (P=0.000). Midodrine and rifaximin significantly reduced paracentesis needs when compared with the controls (18 study patients vs. 75 DT-only patients, P=0.000). Adding rifaximin and midodrine to DT enhanced diuresis in refractory ascites with improved systemic, renal hemodynamics and short-term survival.

Hepatorenal syndrome (HRS) is a severe complication of liver cirrhosis, with poor survival. Rifaximin is a gut-selective broad-spectrum antibiotic. The aim of this study was to evaluate the role of rifaximin as a primary prevention of HRS. Eighty patients with liver cirrhosis and ascites were enrolled. They were randomized into two groups: control (n=40) and rifaximin group (n=40). Baseline liver function tests, renal function tests, complete blood count, international normalized ratio, urine analysis, and abdominal ultrasonography were carried out. Rifaximin 550 mg was administered twice daily for 12 weeks. Renal functions were measured every 4 weeks with monitoring of HRS occurrence and possible precipitating factor. Both groups were matched for age, sex, virology, serum bilirubin, serum albumin, aspartate aminotransferase, alanine aminotransferase, hemoglobin, white blood cells, platelets, international normalized ratio, potassium, and Child-Pugh score. In contrast to the rifaximin group, the control group showed statistically significant serial blood urea nitrogen (18.84±7.17, 19.85±6.10, 21.54±4.79, and 22.96±5.82 mg/dl; P=0.001) and serum creatinine (0.94±0.25, 1.02±0.24, 1.12±0.16, and 1.21±0.17 mg/dl; P=0.001) levels. The overall blood urea nitrogen and serum creatinine change was statistically higher in the control group than the rifaximin group (20.8 vs. 18.24 mg/dl and 1.07 vs. 0.99 mg/dl, respectively). HRS developed more in the control group than the rifaximin group [9 (22.5%) vs. 2 (5%); P=0.048]. In both groups, HRS was precipitated by spontaneous bacterial peritonitis mainly and large volume paracentesis. The Child-Pugh score, control group, baseline serum sodium, and creatinine were predictors of HRS. Rifaximin may be useful as a primary prevention of HRS.

Here we report a prospective study on whether a temporary suprapubic catheter (SPC) can be safely inserted as a substitute for transurethral balloon catheterization during laparoscopy-assisted colectomy. Our subjects included 52 cases who gave informed consent to have an SPC inserted. These subjects were selected from cases who underwent laparoscopy-assisted surgery for primary colorectal cancer from October 2014 to August 2015. An SPC was inserted into 45 of the original 52 cases. The median surgical duration was 220 min (range, 11-438 min), and the SPC insertion was performed at a median of 133 min (range, 9-384 min) after the start of surgery. Insertion required a median duration of 116 s. In one case (2.2%), the bladder was perforated by the paracentesis needle, and in two cases (4.4%), hematuria was observed at the time of insertion; however, surgery was completed without any incident in these three cases. Six of the remaining 42 cases (13.3%) demonstrated neither micturition desire nor independent urination on the day the catheter was clamped. In these cases, the clamp was released two to four times, and draining of an average of 586-mL urine, micturition desire, and independent urination were confirmed 2-4 days later. Transurethral balloon catheterization is a simple procedure that is commonly used on surgical patients, but it can cause pain, discomfort, and infection. In contrast, SPC insertion is a procedure that avoids crossing the urethra and its associated disadvantages. Here we were able to demonstrate that the procedure can be safely used in laparoscopic surgery patients. © 2018 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Corneal permeability of drugs is an important factor used to assess the efficacy of topical preparations. Transcorneal penetration of drugs from aqueous formulation is governed by various physiological, physiochemical, and formulation factors. In the present study, we investigated the effect of formulation factors like concentration, pH, and volume of instillation across the cornea using cassette dosing technique for ophthalmic fluoroquinolones (FQs). Sterile cocktail formulations were prepared using four congeneric ophthalmic FQs (ofloxacin, sparfloxacin, pefloxacin mesylate, and gatifloxacin) at concentrations of 0.025%, 0.5%, and 0.1%. Each formulation was adjusted to different pH ranges (4.5, 7.0, and 8.0) and assessed for transcorneal penetration in vivo in rabbit's cornea (n=4 eyes) at three different volumes (12.5, 25, and 50 μL). Aqueous humor was aspirated through paracentesis after applying local anesthesia at 0, 5, 15, 30, 60, 120, and 240 minutes postdosing. The biosamples collected from a total of 27 groups were analyzed using liquid chromatography-tandem mass spectroscopy to determine transcorneal permeability of all four FQs individually. Increase in concentration showed an increase in penetration up to 0.05%; thereafter, the effect of concentration was found to be dependent on volume of instillation as we observed a decrease in transcorneal penetration. The highest transcorneal penetration of all FQs was observed at pH 7.0 at concentration 0.05% followed by 0.025% at pH 4.5. Lastly, increasing the volume of instillation from 12.5 to 50 μL showed a significant fall in transcorneal penetration. The study concludes that formulation factors showed discernible effect on transcorneal permeation; therefore, due emphasis should be given on drug development and design of ophthalmic formulation.

Fuchs' heterochromic cyclitis: a post-infectious manifestation of ocular toxoplasmosis?

The purpose of this article is to report the development of Fuchs' heterochromic cyclitis (FHC) secondary to toxoplasmosis chorioretinitis. The design is based on observational case series report. We report in this article six cases of typical FHC developing secondary to ocular toxoplasmosis. Intraocular immunoglobulin G production against Toxoplasma gondii was determined in the aqueous humor of five patients by calculation of the Goldmann-Witmer coefficient (GWC). The clinical examination revealed typical FHC with no active chorioretinal scar. We report on five women and one man (aged 33-64 years old; median 44.6 years) who developed FHC over a period of time ranging from 2-13 years. A positive GWC (>3) was found in four patients; of the two remaining patients one was negative and the other did not have anterior chamber paracentesis. Four patients were treated for an active ocular toxoplasmic lesion before the development of FHC with pyrimethamine, sulfadiazine and corticosteroids. Two patients had negative anti-toxoplasmic therapy for FHC (one with trimethoprim-sulfamethoxazole for 3 weeks and the other with pyrimethamine, sulfadiazine and corticosteroids for 8 weeks). One never had any treatment. All the patients had mild anterior chamber reaction with no synechia, diffuse and characteristic white stellate keratic precipitates and vitritis; five patients had posterior subcapsular cataract and heterochromia and three had elevated intraocular pressure. The findings help us to conclude that FHC can develop over a period of time after ocular toxoplasmosis. This could be a main association to search for when a Fuchs' uveitis is found with a chorioretinal scar. Ocular inflammation does not mean reactivation of ocular toxoplasmosis. FHC could be a secondary immune reaction with a past antigenic stimulation to a previous infection, i.e., toxoplasmosis, etc.

The current case describes a rare diagnosis of iatrogenic air emboli after elective cardiopulmonary bypass that was successfully treated with delayed hyperbaric oxygen therapy, with good clinical evolution in spite of rare complications. A 35 years old male was admitted to the intensive care unit (ICU) for post-operative management after being placed on cardiopulmonary bypass (CPB) for an elective ventricular septal defect closure and aortic valvuloplasty. The patient initially presented with pathologically late awakening and was extubated 17 h after admission. Neurologic clinical status after extubation showed global aphasia, mental slowness and spatio-temporal disorientation. The injected cerebral CT scan was normal; the EEG was inconclusive (it showed metabolic encephalopathy without epileptic activity); and the cerebral MRI done 48 h after surgery showed multiple small subcortical acute ischemic lesions, mainly on the left fronto- parieto- temporo-occipital lobes. He was taken for hyperbaric oxygen therapy (HOT) over 54 h after cardiac surgery. The first session ended abruptly after 20 min when the patient suffered a generalised tonico-clonic seizure, necessitating a moderately rapid decompression, airway management, and antiepileptic treatment. In total, the patient received 7 HOT sessions over 6 days. He demonstrated full neurological recovery at 4 weeks and GOS (Glasgow Outcome Scale) of 5 out of 5 even after a long delay in initial management. Convulsions are a rare complication of HOT either due to reperfusion syndrome or hyperoxic toxicity and can be managed. Prior imaging by MRI or tympanic paracentesis (myringotomy) should not add further delay of treatment. HOT should be initiated upon late awakening and/or neurologic symptoms after CPB heart surgery, after exclusion of formal counter-indications, even if the delay exceeds 48 h.

To assess the utility of viscoelastic injection to induce bleb expansion and decrease intraocular pressure (IOP) in eyes with encapsulated glaucoma tube shunt blebs. Case series. Forty-three glaucomatous eyes, including 13 eyes with congenital, 13 uveitic, 5 neovascular, 5 open angle, 4 narrow angle and 3 traumatic glaucomas. Methods, interventions or testing: All patients underwent viscoelastic flush procedure. A pre-bent 27 or 30-gauge cannula was passed through a 25-gauge paracentesis, advanced over the iris across the anterior chamber, and insinuated into the tube shunt lumen. Once the cannula was firmly lodged in position, 0.45 to 0.85 ml of viscoelastic was injected to hyperinflate the bleb. Paired t-tests were performed comparing preoperative IOP and number of medications used preoperatively vs levels measured at 1, 6, 12, 18 and 24 months. Intraocular pressure was reduced from a mean preoperative level of 26.0 ± 1.2 (sem) mm Hg to 15.8 ± 1.0 at 1 month, remaining stable thereafter at each 6-month interval with 15.1 ± 1.1 mm Hg at 24 months (p < 0.0001). Medication use did not vary significantly from baseline. Pressure remained < 21 mm Hg after 2 years in 85% of eyes cannulated within 1 year of primary tube shunt implantation (n = 23), and in 62% of eyes cannulated more than 1 year after tube shunt placement (n = 20). Tube shunt expansion with bolus viscoelastic flush successfully restored encapsulated bleb function, providing a substantial (~10 mm Hg) IOP decrease into the mid-normal pressure range. This persisted in the majority of treated eyes for the entire study period. How to cite this article: Groth SL, Greider KL, Sponsel WE.

Abstract Hospitalizations for advanced liver disease are costly and associated with significant mortality. This population-based study aimed to evaluate factors associated with in-hospital mortality and resource use for the management of hospitalized patients with cirrhosis. Mortality records and resource utilization for 52,027 patients hospitalized with cirrhosis and/or complications of portal hypertension (ascites, hepatic encephalopathy, variceal bleeding, spontaneous bacterial peritonitis, or hepatorenal syndrome) were extracted from a nationally representative sample of Thai inpatients covered by Universal Coverage Scheme during 2009 to 2013. The rate of dying in the hospital increased steadily by 12% from 9.6% in 2009 to 10.8% in 2013 (P < .001). Complications of portal hypertension were independently associated with increased in-hospital mortality except for ascites. The highest independent risk for hospital death was seen with hepatorenal syndrome (odds ratio [OR], 5.04; 95% confidence interval [CI], 4.38–5.79). Mortality rate remained high in patients with infection, particularly septicemia (OR, 4.26; 95% CI, 4.0–4.54) and pneumonia (OR, 2.44; 95% CI, 2.18–2.73). Receiving upper endoscopy (OR, 0.29; 95% CI, 0.27–0.32) and paracentesis (OR, 0.93; 95% CI, 0.87–1.00) were associated with improved patient survival. The inflation-adjusted national annual costs (P = .06) and total hospital days (P = .07) for cirrhosis showed a trend toward increasing during the 5-year period. Renal dysfunction, infection, and sequelae of portal hypertension except for ascites were independently associated with increased resource utilization. Renal dysfunction, infection, and portal hypertension-related complications are the main factors affecting in-hospital mortality and resource utilization for hospitalized patients with cirrhosis. The early intervention for modifiable factors is an important step toward improving hospital outcomes. PMID:28796076

Albumin constitutes approximately one half of the proteins in the plasma and plays a pivotal role in modulating the distribution of fluid between body compartments. Hence it is commonly employed in cirrhotic patients in association with diuretics for the treatment of ascites. Nevertheless, its usefulness is controversial in this condition and well-stated only in some circumstances. The item of safety of the drug appears to be convincing due to the accurate cautions in the course of its preparation. Side effects are described in literature only as sporadic events. Indeed, albumin administration is effective to prevent the circulatory dysfunctions after large-volume paracentesis and renal failure and after Spontaneous Bacterial Peritonitis (SBP). Finally albumin represents, associated with vasoconstrictors, the therapeutic gold standard for the hepatorenal-syndrome (HRS). Physiopathological bases of the therapeutic use of albumin in hepatic cirrhosis consist in both hypoalbuminemia and portal hypertension consequences. In fact, cirrhotic patient with ascites, in spite of hydrosaline retention, shows an effective hypovolemia with peripheral arterial vasodilatation and increase in heart rate. Therefore the effectiveness of albumin administration in the treatment of ascites is due to its plasma volume expander property as well as its efficacy in restoring plasmatic oncotic pressure. Trials are in progress in order to define the effectiveness of the prolonged home-administration of human albumin in the treatment and prevention of ascites. Finally, it has been recently demonstrated that the binding, transport and detoxification capacities of human albumin are severely reduced in cirrhotics and this impairment correlates with the degree of liver failure. Therefore, the next challenge will be to determine whether the alterations of non-oncotic properties of albumin are able to forecast mortality in cirrhotics with ascites and exogenous albumin chronic administration will be

Pediatric literature on spontaneous bacterial peritonitis (SBP) is limited. We evaluated the prevalence, subtypes, clinical profile, and effect on outcome of ascitic fluid infection (AFI) in children with liver disease. Children with liver disease-related ascites and subjected to paracentesis were classified as no-AFI and AFI (SBP, culture-negative neutrocytic ascites [CNNA], and monomicrobial non-neutrocytic bacterascites). Clinical and laboratory parameters, in-hospital mortality, and outcome in follow-up were noted. Two hundred sixty-two children (163 boys; age 84 [1-240] months, chronic liver disease [CLD, n = 173], non-CLD [n = 89]) were enrolled. A total of 28.6% (n = 75) had SBP/CNNA, more common in CLD than non-CLD (55/173 [31.7%] vs 20/89 [22.4%]; P = 0.1). A total of 50.6% SBP/CNNA cases were symptomatic for AFI. Gram-negative bacilli were isolated from 70% SBP cases. Twenty-five percent (18/72) CLD children with AFI had a poor hospital outcome, with INR, Child-Pugh score and gastrointestinal bleeding predicting outcome on multivariate analysis. Patients with CLD with SBP had higher in-hospital mortality (10/20 vs 5/35; P = 0.01) than those with CNNA, but similar Child-Pugh score (12[7-15] vs 11[7-14]; P = 0.1), recurrence of AFI (3/9 vs 6/24; P = 0.6) and mortality in follow-up (22.2% vs 25%; P = 0.1). Patients with CLD with SBP/CNNA had higher mortality over 1 year follow-up than no-AFI (24.2% [8/33] vs 12.2% [7/57]; P = 0.1) but the difference was not significant. A total of 28.6% children with liver disease-related ascites have SBP/CNNA; 50% are symptomatic. Patients with CLD with SBP/CNNA have a mortality of 24% over 1year follow-up. CLD with SBP is similar to CNNA except for higher in-hospital mortality.

Spontaneous bacterial peritonitis (SBP) is a common, life-threatening complication of liver cirrhosis. Third-generation cephalosporins have been considered the first-line treatment of SBP. In 2014, a panel of experts suggested a broader spectrum antibiotic regimen for nosocomial SBP, according to the high rate of bacteria resistant to third-generation cephalosporins found in these patients. However, a broader-spectrum antibiotic regimen has never been compared to third-generation cephalosporins in the treatment of nosocomial SBP. The aim of our study was to compare meropenem plus daptomycin versus ceftazidime in the treatment of nosocomial SBP. Patients with cirrhosis and nosocomial SBP were randomized to receive meropenem (1 g/8 hours) plus daptomycin (6 mg/kg/day) or ceftazidime (2 g/8 hours). A paracentesis was performed after 48 hours of treatment. A reduction in ascitic fluid neutrophil count <25% of pretreatment value was considered a treatment failure. The primary outcome was the efficacy of treatment defined by the resolution of SBP after 7 days of treatment. Thirty-two patients were randomized and 31 were analyzed. The combination of meropenem plus daptomycin was significantly more effective than ceftazidime in the treatment of nosocomial SBP (86.7 vs. 25%; P < 0.001). Ninety-day transplant-free survival (TFS) was not significantly different between the two groups. In the multivariate analysis, ineffective response to first-line treatment (hazard ratio [HR]: 20.6; P = 0.01), development of acute kidney injury during hospitalization (HR: 23.2; P = 0.01), and baseline mean arterial pressure (HR: 0.92; P = 0.01) were found to be independent predictors of 90-day TFS. The combination of meropenem plus daptomycin is more effective than ceftazidime as empirical antibiotic treatment of nosocomial SBP. Efficacy of the empirical antibiotic treatment is a strong predictor of 90-day survival in patients with nosocomial SBP. © 2015 by the American

Malignant ascites (MA) is a sign of advanced cancer and poor prognosis. MA can result in impairment in quality of life (QOL) and significant symptoms. As a supportive treatment, ascites can be drained by paracentesis (PC), percutaneously implanted catheters (tunneled, untunneled, central venous catheters), or peritoneal ports, or peritoneovenous shunts. The aim of this study was to evaluate the effectiveness, safety, and patient-reported outcomes (PRO) of different drainage methods for the management of MA. A systematic review of the literature was performed, and 32 original articles met the inclusion criteria. Patients selected for permanent drain insertion demonstrated symptoms related to MA and had undergone repeated PC. The primary focus of the reviewed articles was procedural safety issues. The rate of technical success of drainage device installation was 100%. Most patients experienced improvements in symptom control after ascites drainage. When analyzed together, 19.7% (255/1297) of patients experienced any complication and 6.2% (81/1297) experienced serious adverse events during MA drainage. Complications were reported for every drainage method; however, the least occurred after PC or central venous catheter, while the most serious occurred after peritoneovenous shunts. Adverse events were as follows: catheter obstruction: 4.4%, infection: 4.1%, leakage: 3.5%, catheter dislodgment: 2.3%, hypotension: 0.6%, injuries during device insertion: 0.6%, renal impairment: 0.5%, electrolyte imbalance: 0.2%, other: 3.6%. PRO and QOL endpoints were available for 12 studies. When PRO were measured using an interview, a significant improvement in symptom control and QOL was reported in almost all patients. Once standardized questionnaires were used, improvements in symptomatic scores and role functioning were observed. Deterioration was observed in cognitive and emotional subscales. MA drainage is a safe and effective method to control symptoms associated with ascites

Although more palliative care is necessary for terminally ill cancer patients, excess investigational tests, invasive procedures, and treatments are given instead. Between November 2009 and December 2013, six hundred and twenty-four patients with end-stage cancer who were died at inpatient setting evaluated retrospectively. Patients' characteristics, sites of tumor and metastasis, tests and invasive procedures, treatments performed in the last 2 weeks before death were collected from the hospital files and analyzed. Median age of 624 patients was 58 (range 16-96) years. More than half of the patients (370, 59.3%) were men. The most frequent cancer sites were gastrointestinal (GI) system (32.2%), lung (24.0%), and breast (11.1%). Frequent metastatic sites were liver (34.8%), bone (31.5%), lung (23.3%), and/or brain (16.9%). Causes of death were respiratory failure, infections, and/or liver failure in 49.9, 23.9, and 19.4% of patients, respectively. Radiological tests performed in the last 2 weeks before death were ultrasonography, computed tomography, magnetic resonance imaging, bone scan in 25.6, 16.3, 11.4, and 3.8% of patients, respectively. Treatments received were intravenous (i.v) serum infusion, blood transfusion, total parenteral nutrition (TPN), human albumin infusion in 55.9, 44.1, 34.9, and 9.5% of patients, respectively. Invasive procedures such as invasive pain relief, terminal sedation, and chemotherapy performed in 12.6, 4.4, and 10.0% of patients, respectively. Central venous catheter application, paracentesis, thoracentesis, and GI endoscopy were applied in 41.7, 9.8, 5.6, and 3.4% of the patients, respectively. Radiological tests, invasive procedures, TPN, and human albumin transfusion were used excessively in terminal stage cancer patients in our medical oncology inpatient clinics. Invasive pain relief and terminal sedation were still underused in our cancer clinics. There is an urgent need in developing national palliative care program to improve

Serum-ascites albumin gradient (SAAG) has been used in the classification of ascites for the last 20 years but it has some drawbacks. This study searches for possible correlations between ascitic fluid viscosity and the etiology of ascites, renal impairment, and length of ICU stay. The study was conducted in Zagazig University Hospital, Egypt. It included 240 patients with ascites due to various causes. The patients were divided into two groups: the cirrhotic ascites group, which included 120 patients, and the noncirrhotic ascites group, which included 120 patients. Ascitic patients on medical management with diuretics, antibiotics, paracentesis, and infusion of plasma or albumin were excluded.The laboratory analysis included routine investigations to detect the cause of ascites as well as specific investigations such as ascitic fluid viscosity using a falling ball viscosimeter (microviscosimeter) at 37°C. The mean ascitic viscosity of patients with SAAG at least 1.1 was 1.16±0.56, which was associated with serum creatinine 1.35±0.52 mg/dl and ICU stay of 3.3±1.2 days. In patients with SAAG less than 1.1 g/dl, the mean ascitic viscosity was 2.98±0.87, with serum creatinine 2.1±0.56 mg/dl and ICU stay of 7.1±1.3 days. Ascitic viscosity can discriminate ascites due to portal hypertension from those associated with nonportal hypertension at a cut-off value of 1.65; it can predict renal impairment in hepatic patients at a cut-off of 1.35 and long ICU stay at a cut-off of 1.995 using receiver operating characteristic analysis. Ascitic viscosity measurement is rapid, inexpensive, and requires small sample volumes. Ascitic viscosity can discriminate ascites due to portal hypertension from those associated with nonportal hypertension at a cut-off value of 1.65. It can predict renal impairment in hepatic patients at a cut-off of 1.35 and long ICU stay at a cut-off of 1.995.

To measure the achievable perioperative aqueous concentration of the commercially available topically administered fourth generation fluoroquinolones, moxifloxacin 0.5% ophthalmic solution, and gatifloxacin 0.3% ophthalmic solution, and to correlate this concentration with the agents' biological efficacy in the aqueous humor of patients undergoing routine cataract surgery. Prospective, randomized, parallel, double-masked, clinical trial. Fifty patients undergoing cataract extraction. Patients (n = 25) were given perioperative topical moxifloxacin 0.5% or topical gatifloxacin 0.3% (n = 25). One drop of antibiotic was administered every 10 minutes for 4 doses beginning 1 hour prior to surgery. Aqueous humor was sampled via paracentesis and antibiotic concentrations were determined using validated high performance liquid chromatography (HPLC) procedures. Dilution analyses were performed to determine the biological efficacy of the agents in the aqueous against Staphylococcus epidermidis, the most common cause of postcataract endophthalmitis. Aqueous humor antibiotic concentrations were measured using HPLC and microdilution bioassay techniques. Biological activity was measured as minimal inhibitory dilution and minimal bactericidal dilution. Aqueous humor concentrations for moxifloxacin via HPLC analysis were 1.80 (+/-1.21) microg/ml, whereas those for gatifloxacin were 0.48 (+/-0.34) microg/ml. This 3.8-fold difference in aqueous humor antibiotic concentrations was statistically significant (P = 0.00003). Similarly, the biological dilution analysis of the aqueous humor samples showed that moxifloxacin attained an estimated activity of 2.1 microg/ml, whereas the gatifloxacin activity was approximately 0.4 mug/ml, which represented a 4.9-fold difference. This study demonstrated that after topically administered perioperative antibiotics with cataract surgery, moxifloxacin 0.5% ophthalmic solution achieved a statistically significantly higher concentration in aqueous

Patients with decompensated cirrhosis have significantly reduced survival without liver transplantation. Granulocyte colony-stimulating factor (G-CSF) has been shown to increase survival in patients with acute-on-chronic liver failure, and erythropoietin promoted hepatic regeneration in animal studies. We performed a double-blind, randomized, placebo-controlled trial to determine whether co-administration of these growth factors improved outcomes for patients with advanced cirrhosis. In a prospective study, consecutive patients with decompensated cirrhosis seen at the Institute of Liver and Biliary Sciences, New Delhi (from May 2011 through June 2012) were randomly assigned to groups given subcutaneous G-CSF (5 μg/kg/d) for 5 days and then every third day (12 total doses), along with subcutaneous darbopoietin α(40 mcg/wk) for 4 weeks (GDP group, n = 29), or only placebos (control group, n = 26). All patients also received standard medical therapy and were followed for 12 months. Histology was performed on liver biopsies. The primary end point was survival at 12 months. Baseline characteristics of patients were comparable; alcohol intake was the most common etiology of cirrhosis. A higher proportion of patients in the GDP group than controls survived until 12 months (68.6% vs 26.9%; P = .003). At 12 months, Child-Turcotte Pugh scores were reduced by 48.6% in the GDP group and 39.1% in the control group, from baseline (P = .001); Model for End Stage Liver Disease scores were reduced by 40.4% and 33%, respectively (P = .03). The need for large-volume paracentesis was significantly reduced in GDP group, compared with controls (P < .05). A lower proportion of patients in the GDP group developed septic shock (6.9%) during follow-up compared with controls (38.5%; P = .005). No major adverse events were observed in either group. In a single-center randomized trial, a significantly larger proportion of patients with decompensated cirrhosis given a combination of G-CSF and

To evaluate the diagnostic accuracy of the Serum-Ascites Albumin Gradient (GASA), Protein Concentration in the Ascitic Fluid (PTLA), Albumin Concentration in the ascitic fluid (CAA) and the Protein Ascites/Serum Ratio (IPAS) for the diagnosis of ascites due to portal hypertension. it was an observational and retrospective study of validation of diagnostic tests. The study population was patients from a National Public Health Hospital Daniel Alcides Carrion of Callao, Peru, during the period January to December of 2012, patients over 15 years old with a diagnosis of ascites which samples were taken for study by paracentesis with an standard technique, it was analyzed total protein and albumin, as well as study of total protein and albumin in blood. We obtained the diagnostic accuracy, sensitivity, specificity, PPV and NPV of the Serum-Ascites Albumin Gradient (GASA), Protein Concentration in the Ascitic Fluid (PTLA), Albumin Concentration in the ascitic fluid (CAA) and the Protein Ascites/Serum Ratio (IPAS) for the diagnosis of ascites due to portal hypertension. To determine ascites by HTP as diagnostic tests we took into account: GASA >= 1.1, PTLA <2.5, CAA <1.1 or IPAS< 0.5. There were 126 patients diagnosed with ascites, 10 patients was excluded for having incomplete data. Of the 116 patients, the average age was 53.03 +/- 15.73 years old, male 65 (56%) and female 51 (44%). 61 (52%) had ascites due to portal hypertension from liver cirrhosis, and 55 (48%) of ascites due to NO HTP. The sensitivity and specificity for GASA was 93% and 47% respectively, for PTLA was 80% and 89% respectively, for CAA was 85% and 87% respectively and for the IPAS was 83% and 80% respectively. The área under the ROC curve for GASA was 0.70, ATPL was 0.84, IPAS was 0.81 and CAA was 0.86, we found statistically significant differences between GASA compared to the other three parameters (p<0.01 ). The diagnostic accuracy of CAA, ATPL and IPAS is higher than the GASA to discriminate

The aim of this study was to better understand the role of apoptosis in a retinal ischaemia-reperfusion injury model and to determine whether sildenafil citrate treatment can prevent retinal cell apoptosis. Thirty-six rats were divided into a control group (n = 6) and two experimentally induced ischaemia-reperfusion groups (7 and 21 days; n = 15 per group). The induced ischaemia-reperfusion groups were treated with sildenafil for 7 and 21 days (n = 10 per group), and 10 animals were treated with a placebo for the same period (n = 5 per group). Paracentesis of the anterior chamber was performed with a 30-G needle attached to a saline solution (0.9%) bag positioned at a height of 150 cm above the eye for 60 min. Intraocular pressure was measured by rebound tonometer (TonoVet ® ). The eyes were analysed by histology and morphometry, and by immunohistochemistry and qRT-PCR for expression of Caspase-7, Caspase-6, Caspase-9, Tnf-r2, Fas-l, Bcl-2 and Bax. Sildenafil-treated animals showed lower levels of histopathological changes (inflammatory, cellular and tissue) than their placebo-treated counterparts at both 7 and 21 days. The retinal ganglion cell layer (RGC) was preserved in the sildenafil groups (SG), with a cell count closer to control than in the placebo groups (PG). Caspase-7 expression was significantly higher in both treated groups at 7 days compared to controls. Gene expression levels in both treatment groups differed from the controls, but in SG Bax and Caspase-6 expression levels were similar to control animals. These results suggest that the main mechanism of retinal cell death in this model is apoptosis, as there is an increase in pro-apoptotic factors and decrease in the anti-apoptotic ones. Also, sildenafil seems to protect the retinal ganglion cell layer from apoptosis. Cell survival was evident in the histological and morphometric analyses, and sildenafil treatment had a protective effect in the apoptosis pathways, with gene expression

Leffler, Christopher T; Schwartz, Stephen G

Introduction: John Thomas Woolhouse (1666-1733/1734), who practiced in Paris, was part of a family with 5 generations of English oculists. Some historians have derided him as a “charlatan” and have criticized him for adhering to the old notion that a cataract was a membrane anterior to the lens. Methods: We reviewed treatises and digital records related to Woolhouse and his family and the handwritten notes of his 1721 lecture series at the Royal Society of Medicine. Results: We have identified 5 generations of oculists in Woolhouse’s family, by the names of Atwood, Stepkins, Ivy, and Beaumont. Woolhouse taught students from across Europe. He was one of the early proponents in Europe, inspired by Asian medical practices, to perform paracentesis to release aqueous for a new condition called hydrophthalmia. In Woolhouse’s system, some of these cases probably described angle-closure glaucoma. He was the first to attach the name glaucoma to the palpably hard eye in 1707. He may also have been the first to teach that a soft eye was unlikely to recover vision. Credit for these teachings has traditionally gone to one of his students, Johannes Zacharias Platner, in 1745. Some historians have stated that he proposed iridectomy as a theoretical procedure, which was later performed by Cheselden. In fact, Woolhouse described techniques he had performed which today would be called pupilloplasty, synechiolysis, or pupillary membrane lysis. He was also a pioneer in dacryocystectomy for chronic dacryocystitis and in congenital cataract surgery. His writings from 1716 onward repeatedly (and correctly) stressed that most of the patients with visual disorders required depression of the crystalline lens (for what he called glaucoma), as opposed to removal of an anterior membrane (which he called cataract). Conclusions: Woolhouse was a bold ophthalmic innovator and teacher who made major contributions which have lasted to this day. Although he did not admit it, he ultimately

Mortality in spontaneous bacterial peritonitis (SBP) decreased significantly from 90% in 1970 to 10-30% today, but SBP still remains a complication with a poor prognosis. Although there are new preventive measures, such as early diagnosis and treatment with albumin, the introduction of new antibiotics, the prognosis of patients with decompensated cirrhosis and SBP remains poor, with a mortality rate of 20-40%. The installation of an episode of spontaneous bacterial peritonitis reduces the survival rate at 1 year to 30% and to 20% at 2 years. In this context, the identification of patients with increased risk of death is extremely important in order to improve prognosis. The prospective study included 153 patients with cirrhosis admitted to the Institute of Gastroenterology and Hepatology Iaşi from 1 January to 31 December 2010, reevaluated during 2 years. Criteria for the diagnosis of SBP were the presence of a number > 250 PMN / mmc. The presence of ascites and/or upper gastrointestinal bleeding (UGB) marks the decompensated cirrhosis. To assess the severity of cirrhosis, there were used Child-Pugh and MELD scores. Diagnostic paracentesis and ascites fluid cultures were performed in all hospitalized patients with ascites and also in case of signs and symptoms of SBP, before and after antibiotic treatment. Lack of response to empirical therapy was considered in those cases with a decrease in the number of neutrophils < 25% from baseline. Identification of patients with increased risk of death is extremely important to improve prognosis. In peripheral leukocytosis and in the ascites fluid, low hemoglobin can be considered predictors of mortality in patients with PBS. Child-Pugh score, increased levels of bilirubin and creatinine and hyponatremia are independent risk factors of mortality in patients with SBP. Bacteremia and lack of therapeutic response are independent risk factors of mortality associated with SBP. Recent history of variceal bleeding, severity of

Veno-occlusive disease (VOD) is a potentially fatal complication of hematopoietic stem cell transplantation (HSCT). Patients with VOD are often critically ill and require close collaboration between transplant physicians and intensivists. We surveyed members of a consortium of pediatric intensive care unit (PICU) and transplant physicians to assess variability in the self-reported approach to the diagnosis and management of VOD. An internet-based self-administered survey was sent to pediatric HSCT and PICU providers from September 2014 to February 2015. The survey contained questions relating to the diagnosis and treatment of VOD. The response rate was 41% of 382 providers surveyed. We found significant variability in the diagnostic and management approaches to VOD in children. Even though ultrasound is not part of the diagnostic criteria, providers reported using reversal of portal venous flow seen on abdominal ultrasound in addition to Seattle criteria (70%) or Baltimore criteria to make the diagnosis of VOD. Almost 40% of respondents did not diagnose VOD in anicteric patients (bilirubin < 2 mg/dL). Most providers (75%) initiated treatment with defibrotide at the time of diagnosis, but 14%, 7%, and 6% of the providers waited for reversal of portal venous flow, renal dysfunction, or pulmonary dysfunction, respectively, to develop before initiating therapy. Only 50% of the providers restricted fluids to 75% of the daily maintenance, whereas 21% did not restrict fluids at all. Albumin with diuretics was used by 95% of respondents. Platelets counts were maintained at 20,000 to 50,000/mm(3) and 10,000 to 20,000/mm(3) by 64% and 20% of the respondents, respectively. Paracentesis was generally initiated in the setting of oliguria or hypoxia, and nearly 50% of the providers used continuous drainage to gravity, whereas the remainder used an intermittent drainage approach. Nearly 73% of the transplant providers used VOD prophylaxis, whereas the remainder did not use any

Infants presenting with lysosomal acid lipase deficiency have marked failure to thrive, diarrhea, massive hepatosplenomegaly, anemia, rapidly progressive liver disease, and death typically in the first 6 months of life; the only available potential treatment has been hematopoietic stem cell transplantation, which is associated with high morbidity and mortality in this population. The study objective was to evaluate safety and efficacy (including survival) of enzyme replacement with sebelipase alfa in infants with lysosomal acid lipase deficiency. This is an ongoing multicenter, open-label, phase 2/3 study conducted in nine countries. The study enrolled infants with growth failure prior to 6 months of age with rapidly progressive lysosomal acid lipase deficiency; they received once-weekly doses of sebelipase alfa initiated at 0.35 mg/kg with intrapatient dose escalation up to 5 mg/kg. The main outcome of interest is survival to 12 months and survival beyond 24 months of age. Nine patients were enrolled; median age at baseline was 3.0 months (range 1.1-5.8 months). Sixty-seven percent (exact 95% CI 30%-93%) of sebelipase alfa-treated infants survived to 12 months of age compared with 0% (exact 95% CI 0%-16%) for a historical control group (n = 21). Patients who survived to age 12 months exhibited improvements in weight-for-age, reductions in markers of liver dysfunction and hepatosplenomegaly, and improvements in anemia and gastrointestinal symptoms. Three deaths occurred early (first few months of life), two patients died because of advanced disease, and a third patient died following complications of non-protocol-specified abdominal paracentesis. A fourth death occurred at 15 months of age and was related to other clinical conditions. The five surviving patients have survived to age ≥24 months with continued sebelipase alfa treatment; all have displayed marked improvement in growth parameters and liver function.

subsequent embryonic cleavage is comparable to standard hCG treatment. There are no differences in clinical and embryological characteristics in both groups. Only one patient with administration of Pregnyl 10 000 IU i.m. was treated for OHSS grade II by vaginal paracentesis. Administration of triptorelin 0.2 mg s.c. is a safe and effective approach to achieve mature oocytes in egg donation programme, where we do not take care of implantation, which has got some limitations based on several studies.

AIM: To elucidate the efficacies of tolvaptan (TLV) as a treatment for refractory ascites compared with conventional treatment. METHODS: We retrospectively enrolled 120 refractory ascites patients between January 1, 2009 and September 31, 2014. Sixty patients were treated with oral TLV at a starting dose of 3.75 mg/d in addition to sodium restriction (> 7 g/d), albumin infusion (10-20 g/wk), and standard diuretic therapy (20-60 mg/d furosemide and 25-50 mg/d spironolactone) and 60 patients with large volume paracentesis in addition to sodium restriction (less than 7 g/d), albumin infusion (10-20 g/wk), and standard diuretic therapy (20-120 mg/d furosemide and 25-150 mg/d spironolactone). Patient demographics and laboratory data, including liver function, were not matched due to the small number of patients. Continuous variables were analyzed by unpaired t-test or paired t-test. Fisher’s exact test was applied in cases comparing two nominal variables. We analyzed factors affecting clinical outcomes using receiver operating characteristic curves and multivariate regression analysis. We also used multivariate Cox’s proportional hazard regression analysis to elucidate the risk factors that contributed to the increased incidence of ascites. RESULTS: TLV was effective in 38 (63.3%) patients. The best cut-off values for urine output and reduced urine osmolality as measures of refractory ascites improvement were > 1800 mL within the first 24 h and > 30%, respectively. Multivariate regression analysis indicated that > 25% reduced urine osmolality [odds ratio (OR) = 20.7; P < 0.01] and positive hepatitis C viral antibodies (OR = 5.93; P = 0.05) were positively correlated with an improvement of refractory ascites, while the total bilirubin level per 1.0 mg/dL (OR = 0.57; P = 0.02) was negatively correlated with improvement. In comparing the TLV group and controls, only the serum sodium level was significantly lower in the TLV group (133 mEq/L vs 136 mEq/L; P = 0

.v. infusion at low doses or by other inotropic agents provided with recognized renal vasodilator properties and/or by addition to i.v. furosemide of osmotic agents able to expand the hematic volume, so counteracting or minimizing the reflex renal vasoconstriction induced by furosemide-related reduction in intravascular circulating volume: i.v. infusion of small volumes of hypertonic saline solution, as well as administration of albumin, mannitol and/or plasma expanders. Because renal impairment, as developing in the setting of CHF, has proven to represent a very important indicator of adverse outcome, every effort should be addressed to prevent any significant (>25% of basal value) rise in serum creatinine consequent to diuretic unloading therapy or to other procedures (paracentesis of tense ascites, ultrafiltration) aimed at rapid fluid removal in edematous or ascitic CHF or cardiogenetic anasarca. Ultrafiltration, even though a promising technique highly valued for its acknowledged property to obtain a more rapid fluid and weight loss in CHF patients with marked fluid retention, has been demonstrated so far to produce neurohumoral activation, creatinine abnormalities and symptomatic hypotensions similar to those due to i.v. loop diuretics; thus, the hypothesized advantages of this technique remain to be further clarified and confirmed, with regard to its safety profile and cost-effectiveness.

Treatment of the causes of many chronic liver diseases (CLDs) may not be possible. In this case, complications must be anticipated, prevented or at least controlled by the best available therapeutic modalities. There are three main goals for the management of portal hypertension: (i) prevention of the first episode of variceal bleeding largely by non-selective β-adrenoceptor antagonists, which is not generally recommended in children; (ii) control of bleeding by using a stepwise approach from the least to most invasive strategies; (iii) and prevention of re-bleeding using bypass operations, with particular enthusiasm for the use of meso-Rex bypass in the pediatric population. Hepatic encephalopathy management also consists of three main aspects: (i) ruling out other causes of encephalopathy; (ii) identifying and treating precipitating factors; and (iii) starting empiric treatment with drugs such as lactulose, rifaximin, sodium benzoate, and flumazenil. Treatment of mild ascites and peripheral edema should begin with the restriction of sodium and water, followed by careful diuresis, then large-volume paracentesis associated with colloid volume expansion in severe cases. Empiric broad spectrum antimicrobial therapy should be used for the treatment of spontaneous bacterial peritonitis, bacterial and fungal sepsis, and cholangitis, after taking appropriate cultures, with appropriate changes in therapy after sensitivity testing. Empirical therapies continue to be the standard practice for pruritus; these consist of bile acid binding agents, phenobarbital (phenobarbitone), ursodeoxycholic acid, antihistamines, rifampin (rifampicin), and carbamazepine. Partial external biliary diversion can be used in refractory cases. Once hepatorenal syndrome is suspected, treatment should be initiated early in order to prevent the progression of renal failure; approaches consist of general supportive measures, management of concomitant complications, screening for sepsis, treatment

estimate potential revenue. In FY 2007, 486 limited echo exams of abdomen (current procedural terminology [CPT] 76705) and 480 limited echo cardiac exams were performed (CPT 93308) while there were 78 exams for US-guided vascular access (CPT 76937) and 36 US-guided needle placements when performing paracentesis, thoracentesis, or location of abscess for drainage (CPT 76492). Applying the 2007 CMS fee schedule and above assumptions, the revenue generated was 578 RVUs and $35,541 ($12,934 in professional physician fees and $22,607 in facility fees). Assuming optimal documentation rates for diagnostic ED US scans, ED US could have generated 1,487 RVUs and $94,593 ($33,953 in professional physician fees and $60,640 in facility fees). Program expenses include an initial capital expense (estimated at $120,000 for two US machines) and ongoing operational costs ($68,640 per year to cover image quality assurance review, continuing education, and program maintenance). Based on current revenue, there would be an annual operating loss, and thus an ROI cannot be calculated. However, if potential revenue is achieved, the annual operating income will be $22,846 per year with an ROI of 4.9 years to break even with initial investment. Determining an ROI is a required procedure for any business plan for establishing an ED US program. Our analysis demonstrates that an ED US program that captures charges for trauma and procedural US and achieves the potential billing volume breaks even in less than 5 years, at which point it would generate a positive margin.

BACKGROUND: Ascites is defined as the pathological accumulation of fluid in the peritoneal cavity. It is the most common complication of cirrhosis, which is also the most common cause of ascites. Viscosity is a measure of the resistance of a fluid to deform under shear stress. Plasma viscosity is influenced by the concentration of plasma proteins and lipoproteins, with the major contribution from fibrinogen. To our knowledge, the viscosity of ascitic fluid has not yet been studied. OBJECTIVE: To evaluate the role of ascitic fluid viscosity in discriminating between ascites due to portal hypertension-related and nonportal hypertension-related causes, and to compare results with the serum-ascites albumin gradient (SAAG). METHODS: The present study involved 142 patients with ascites presenting with diverse medical problems. Serum total protein, albumin, glucose, lactate dehydrogenase (LDH) levels and complete blood count were obtained for all subjects. Paracentesis was performed routinely on admission and all ascitic fluid samples were evaluated by manual cell count with differential, ascitic fluid culture and biochemistry (total protein, albumin, glucose and LDH). Cultures of ascitic fluid were performed at bedside in all patients using blood culture bottles. Ascitic fluid viscosity was measured in a commercially available cone and plate viscometer. RESULTS: Of the 142 patients studied, 34 (24%) had an SAAG of 11 g/L or less, whereas 108 (76%) had an SAAG of greater than 11 g/L. Sex and mean age did not differ significantly between the two groups (P>0.05). Serum total protein, albumin, glucose, LDH levels, leukocyte count, ascitic fluid glucose levels and ascitic fluid leukocyte counts were similar in both groups, with no statistically significant relationship detected (P>0.05). However, the mean (±SD) ascitic fluid total protein (0.0172±0.1104 g/L versus 0.043±0.011 g/L), albumin (0.0104±0.0064 g/L versus 0.0276±0.0069 g/L) and LDH (102.76±80.95 U/L versus 885
