    Abstract Background Analgesia for neonatal circumcision was recently advocated for every male infant, and its use is considered essential by the American Academy of Pediatrics. We compared the post-operative analgesic quality of bupivacaine to that of lidocaine for achieving dorsal penile nerve block (DPNB) when performing neonatal circumcision. Methods Data were obtained from 38 neonates following neonatal circumcision. The infants had received DPNB analgesia with either lidocaine or bupivac...

    Full Text Available Abstract Background Analgesia for neonatal circumcision was recently advocated for every male infant, and its use is considered essential by the American Academy of Pediatrics. We compared the post-operative analgesic quality of bupivacaine to that of lidocaine for achieving dorsal penile nerve block (DPNB when performing neonatal circumcision. Methods Data were obtained from 38 neonates following neonatal circumcision. The infants had received DPNB analgesia with either lidocaine or bupivacaine. The outcome variable was the administration by the parents of acetaminophen during the ensuing 24 hours. Results Seventeen infants received lidocaine and 19 received bupivacaine DPNB. Ten infants in the lidocaine group (59% were given acetaminophen following circumcision compared to only 3 (16% in the bupivacaine group (P 2 = 20.6; P = 0.006. Conclusion DPNB with bupivacaine for neonatal circumcision apparently confers better analgesia than lidocaine as judged by the requirement of acetaminophen over the ensuing 24-hour period.

    Full Text Available A female neonate was delivered at 30 weeks’ gestation to a mother with suspected bilateral periventricular nodular heterotopia (PNH on computed tomography brain scan. Antenatal ultrasound (US performed at 28 weeks’ gestation showed mild lateral cerebral ventricle dilatation, but no other fetal anomalies. Clinical examination revealed mild dysmorphic features: facial and skull asymmetry, square-shaped ears, and long tapering fingers. Chromosomal analysis showed a 46XX karyotype.

    Neonatal arterial ischaemic stroke (AIS) is an important cause of severe neurological disability. This study aimed to analyse the clinical manifestations and outcomes of AIS patients. We enrolled neonates with AIS admitted to Severance Children's Hospital and Gangnam Severance Hospital between 2008 and 2015. AIS was confirmed using magnetic resonance imaging (MRI). We retrospectively reviewed the clinical manifestations, MRI findings, electroencephalography (EEG) findings and neurodevelopmental outcomes. The study comprised 29 neonates (18 boys). The mean follow-up period was 15.4 months (range 6-44 months), and the mean age at diagnosis was 8.1 days. Seizure was the most common symptom (66%). Bilateral involvement was more common than unilateral involvement (52%). The middle cerebral artery was the most commonly identified territory (79%). Abnormal EEG findings were noted in 93% of the cases. Neurodevelopment was normal in 11 (38%) patients, while cerebral palsy and delayed development were noted in eight (28%) and six (21%) patients, respectively. Patients with bilateral involvement were very likely to have abnormal neurodevelopmental outcomes. Our study showed that abnormal neurodevelopmental outcomes were very likely after cases of neonatal AIS with bilateral involvement, and clinicians should consider early and more effective interventions in such cases. ©2016 Foundation Acta Paediatrica.

    Fourteen patients with bilateral spastic paralysis (an average age of 2 years and 5 months) were examined using magnetic resonance imaging (MRI). Common MRI findings were an enlarged cerebral ventricle, irregular wall, abnormal signal area in the vicinity of the cerebral ventricle, decrease in the content of white matter, and thickening of the callosum. These findings seemed to reflect pathological lesions in periventricular leukomalacia (PVL). Of 3 patients who had been diagnosed as having cystic PVL on neonatal ultrasonography, 2 had cystic lesions in the corresponding areas on MRI. In the other patient with cystic PVL, membrane-like wall between the cyst and the enlarged cerebral ventricle was different from that seen definitely in porencephalie on spin density images. In patients in whom PVL was missed on neonatal ultrasonography, MRI demonstrated PVL. There was correlation between MRI findings and neurological sequelae: the severity of exercise function tended to correlate with the degree of decreased white matter; however, there was no correlation between spread of abnormal signal areas and the severity of exercise function.

    Full Text Available Background: New methods have been introduced to facilitate dental procedures, but the administration of local anesthesia is still necessary to perform pain control during several dental procedures. Aim: To evaluate the effectiveness of the lidocaine Denti-patch ® system versus the lidocaine topical anesthetic gel in children concerning pain reaction during injection. Materials and Methods: One hundred 9-12-year-old cooperative children weighing more than 29 kg in need of bilateral dental treatment requiring maxillary and mandibular injection and not suffering from acute pain as a result of pulpits on the day of treatment were selected. The children were then divided into two groups: Group 1 comprising of 50 children in need of bilateral maxillary treatment and Group 2 compromising of 50 children requiring bilateral mandibular treatment. These groups were further subdivided into subgroups A and B; those receiving Denti-patch ® on one side and lidocaine gel on the contralateral side, respectively. Pain or comfort was evaluated during injection using sound, eye, motor (SEM scale (objective method while, using faces pain rating scale (FPS scale (subjective method after injection by a trained assistant blinded to the procedure. Statistical Analysis Used: Comparison of the results was performed using Mann-Whitney U-test and Wilcoxon signed-ranks test for SEM and FPS score. Result: There was a statistically significant difference between the patch and the gel group for maxilla (P < 0.0001, as well as mandible (P = 0.01 with respect to SEM score given by the children. Similarly, with FPS scale, there was a statistically significant difference between the patch and the gel groups in both maxilla and mandible (P < 0.0001. However, there was no statistical difference between the patch Groups 1A and IIA or the gel Groups 1B and II B. Conclusion: The Denti-patch ® system can significantly reduce the needle injection pain more than the gel.

  14. Neonatal retinoblastoma

    Tero T Kivelä

    2017-01-01

    Full Text Available From 7% to 10% of all retinoblastomas and from 44% to 71% of familial retinoblastomas in developed countries are diagnosed in the neonatal period, usually through pre- or post-natal screening prompted by a positive family history and sometimes serendipitously during screening for retinopathy of prematurity or other reasons. In developing countries, neonatal diagnosis of retinoblastoma has been less common. Neonatal retinoblastoma generally develops from a germline mutation of RB1, the retinoblastoma gene, even when the family history is negative and is thus usually hereditary. At least one-half of infants with neonatal retinoblastoma have unilateral tumors when the diagnosis is made, typically the International Intraocular Retinoblastoma Classification (Murphree Group B or higher, but most germline mutation carriers will progress to bilateral involvement, typically Group A in the fellow eye. Neonatal leukokoria usually leads to the diagnosis in children without a family history of retinoblastoma, and a Group C tumor or higher is typical in the more advanced involved eye. Almost all infants with neonatal retinoblastoma have at least one eye with a tumor in proximity to the foveola, but the macula of the fellow eye is frequently spared. Consequently, loss of reading vision from both eyes is exceptional. A primary ectopic intracranial neuroblastic tumor known as trilateral retinoblastoma is no more common after neonatal than other retinoblastoma. For many reasons, neonatal retinoblastoma may be a challenge to eradicate, and the early age at diagnosis and relatively small tumors do not guarantee the preservation of both eyes of every involved child. Oncology nurses can be instrumental in contributing to better outcomes by ensuring that hereditary retinoblastoma survivors receive genetic counseling, by referring families of survivors to early screening programs when they are planning for a baby, and by providing psychological and practical support

  15. Effects of lidocaine injections into the lateral parabrachial nucleus on dipsogenic and pressor response to central angiotensin 2 in rats

    Menani, Jose Vanderlei; Beltz, Terry G.

    1995-01-01

    This study investigated the effects of bilateral injections of the local anesthetic, lidocaine, into the lateral parabrachial nucleus (LPBN) on the dipsogenic and pressor responses induced by intracerebroventricular (i.c.v.) injection of angiotensin 2 (ANG 2). Centrally injected ANG 2 (50 ng/1 microliter) induced water intake ( IO.2 +/- 0.8 ml/h) and pressor responses (22 +/- 1 mmHg). Prior bilateral injection of 10% lidocaine (200 nl) into the LPBN increased the water intake (14.2 +/- 1.4 ml/h), but did not change the pressor response (17 +/- 1 mmHg) to i.c.v. ANG 2. Lidocaine alone injected into the LPBN also induced a pressor response (23 +/- 3 mmHg). These results showing that bilateral LPBN injection of lidocaine increase water intake induced bv i.c.v. ANG 2 are consistent with electrolytic and neurotoxic lesion studies and suggest that the LPBN is associated with inhibitory mechanisms controlling water intake induced by ANG 2. These results also provide evidence that it is feasible to reversibly anesthetize this brain area to facilitate fluid-related ingestive behavior.

    2017-10-01

    Continuous bilateral thoracic paravertebral blockade has been used for analgesia after cardiac surgery, but its efficacy has never been formally tested. Fifty adult patients were enrolled in a double-blind, randomised, controlled study of continuous bilateral thoracic paravertebral infusion of 0.5% lidocaine (1 mg.kg -1 .hr -1 ) for analgesia after coronary surgery. Control patients received a subcutaneous infusion of lidocaine at the same rate through catheters inserted at the same locations as the study group. The primary outcome was morphine consumption at 48 hours using patient-controlled analgesia (PCA). Secondary outcomes included pain, respiratory function, nausea and vomiting. Serum lidocaine concentrations were measured on the first two post-operative days. There was no difference in morphine consumption or in any other outcome measure between the groups. Serum lidocaine concentrations increased during the study, with a maximum of 5.9 mg.l -1 . There were no adverse events as a consequence of the study. Bilateral paravertebral infusion of lidocaine confers no advantage over systemic lidocaine infusion after cardiac surgery. ISRCTN13424423 ( https://www.isrctn.com ).

    Full Text Available Lidocaine unmasks silent symptoms and eases neuropathic pain in multiple sclerosis patients; however, the effects of lidocaine in neuromyelitis optica have never been reported. We describe the case of a 59-year-old Japanese woman with neuromyelitis optica spectrum disorder who developed optic neuritis 1 day after intravenous lidocaine injection for treating allodynia. Her symptom seemed to result from a relapse of neuromyelitis optica induced by lidocaine administration, and not because of the transient effects of intravenous lidocaine administration. The possibility that lidocaine administration results in relapse of neuromyelitis optica due to its immunomodulating effects cannot be ruled out.

    2014-09-01

    Full Text Available Background: Lidocaine is a local anesthetic and antiarrhythmic agent. There are reports on accidental and intentional cases of poisoning following injection of lidocaine while rare are the fatal cases realized after oral ingestion of lidocaine. Suicidal poisoning with lidocaine pharmaceutical formulations is rare since no pharmaceutical dosage forms for oral use are available except gels and sprays used as local anesthetics in dentistry. Cases: Three cases of suicidal poisoning by ingestion of the content of lidocaine topical spray are reported in the present study. The cases developed episodes of seizure requiring diazepam and other therapeutic modalities upon admission. Eventually, one of the cases expired. Conclusion: To the best of our knowledge, this study is the first reported case of suicidal poisoning after ingestion of this formulation which highlights the fact that lidocaine topical spray formulation may be used for committing suicide. Ingestion of lidocaine present in topical spray can induce varying levels of toxicity that can even be fatal.

    Surgery on fingers is a common procedure in emergency and day care surgery. Adrenaline combined with lidocaine can prolong digital nerve block and provide a bloodless operating field. Extended postoperative pain relief can reduce the need for analgesics and can facilitate hand rehabilitation. Conventionally, adrenaline is avoided at anatomical sites with end arteries such as digits, penis and pinna because of concerns about arterial spasm, ischaemia and gangrene distal to the site of drug infiltration. To assess the safety and efficacy of use of adrenaline (any dilution) combined with lidocaine (any dilution) for digital nerve blocks (fingers and toes). We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 11, 2014), MEDLINE via Ovid SP (1966 to 18 November 2014) and EMBASE via Ovid SP (1980 to 18 November 2014). We also searched specific websites, such as www.indmed.nic.in; www.cochrane-sadcct.org; and www.Clinicaltrials.gov. We included randomized controlled trials (RCTs) that compared the use of adrenaline with lidocaine and plain lidocaine in patients undergoing surgery on digits (fingers and toes). Our primary outcomes were duration of anaesthesia, adverse outcomes such as ischaemia distal to the injection site and cost analysis. Our secondary outcomes were duration of postoperative pain relief and reduced bleeding during surgery. We used standard methodological procedures expected by The Cochrane Collaboration. Two review authors independently extracted details of trial methodology and outcome data from reports of all trials considered eligible for inclusion. We performed all analyses on an intention-to-treat basis. We used a fixed-effect model when no evidence of significant heterogeneity between studies was found and a random-effects model when heterogeneity was likely. We included four RCTs with 167 participants. Risk of bias of the included studies was high, as none of them reported method of randomization, allocation concealment

  5. Studies on the interaction of lidocaine with plasma proteins

    1985-01-01

    This study sought to quantitate lidocaine's interaction with alpha-1-acid glycoprotein (AAG), human serum albumin (HSA), and AAG in the presence of HSA, and to determine the extent of displacement of lidocaine from its binding site(s) by selected cardiovascular drugs (dipyridamole, disopyramide and quinidine). Since the limited experimental work reported in this area has involved the use of a single lidocaine concentration, this study involved the evaluation of a range of lidocaine concentrations. Lidocaine interaction with plasma proteins (AAG and HSA) was studied at 37 0 C using an isothermal equilibrium dialysis system and 14 C-lidocaine HCl. A dialysis membrane (M.W. cutoff 12,000 to 14,000) separated the two chambers of each dialysis cell. The extent of 14 C-lidocaine dialysis was studied with respect to both drug and protein concentrations. Aliquots of each chamber of each of the cells were subjected to liquid scintillation counting (LSC) analyses for 14 C-lidocaine. The ratio of bound to free (R/F) lidocaine was evaluated as a function of AAG concentration from the LSC data. Scatchard and/or Rosenthal analyses were employed to evaluate n and k values where appropriate. Linear and multiple linear regression analyses of the data were appropriately performed

    Proctalgia fugax is characterized by a sudden internal anal sphincter and anorectic ring attack of pain of a short duration. Description of the influence of intravenous lidocaine treatment for proctalgia fugax. A 28-year-old patient suffering of proctalgia fugax for 8 months. Conventional treatment efforts did not improve his condition. A single dose of an intravenous lidocaine infusion completely stopped his pain attacks. Based on the experience reported in this case and the potential benefit of this treatment for proctalgia fugax, controlled studies comparing intravenous lidocaine with placebo should be conducted to confirm the observation and to provide a more concrete basis for the use of intravenous lidocaine for this indication.

    Neonatal effects of drugs administered to mothers before delivery depend on the quantity that crosses the placental barrier, which is determined by the pharmacokinetics of the drug in the mother, fetus, and placenta. Diabetes mellitus can alter the kinetic disposition and the metabolism of drugs. This study investigated the placental transfer of lidocaine and its metabolite monoethylglycinexylidide (MEGX) in pregnant women with gestational diabetes mellitus (GDM) submitted to peridural anesthesia. A total of 10 normal pregnant women (group 1) and 6 pregnant women with GDM (group 2) were studied, all at term. The patients received 200 mg 2% lidocaine hydrochloride by the peridural locoregional route. Maternal blood samples were collected at the time of delivery and, after placental expulsion, blood samples were collected from the intervillous space, umbilical artery, and vein for determination of lidocaine and MEGX concentrations and analysis of the placental transfer of the drug. The following respective lidocaine ratios between the maternal and the fetal compartments were obtained for groups 1 and 2: umbilical vein/maternal peripheral blood, 0.60 and 0.46; intervillous space/maternal blood, 1.01 and 0.88; umbilical artery/umbilical vein, 0.77 and 0.91; and umbilical vein/intervillous space, 0.53 and 0.51. The following MEGX ratios for groups 1 and 2 were, respectively, fetal/maternal, 0.43 and 0.97; intervillous space/maternal blood, 0.64 and 0.90; umbilical artery/umbilical vein, 1.09 and 0.99; and umbilical vein/intervillous space, 0.55 and 0.78. Gestational diabetes mellitus did not affect the transplacental transfer of lidocaine but interfered with the transfer of MEGX, acting as a mechanism facilitating the transport of the metabolite. © The Author(s) 2015.

    Full Text Available This blinded, randomized experimental study was designed to evaluate the analgesic effects of adding epinephrine or xylazine to lidocaine solution for brachial plexus block (BPB in sheep. Nine healthy, fat-tailed female lambs (26.6 ± 1.5 kg were randomly allocated into three groups: lidocaine 2%, 5 mg kg-1 (LID, n = 6, lidocaine (5 mg kg-1 with epinephrine 5 μg mL-1 (LIDEP, n = 6 or lidocaine (5 mg kg-1 with xylazine 0.05 mg kg-1 (LIDXY, n = 6. Each animal was tested twice. The sheep received a total volume of 0.25 mL kg-1 for BPB. A nerve stimulator was used to locate the nerves of the brachial plexus. Onset and duration of analgesia of the forelimb were evaluated using superficial and deep pin prick and pinching of skin with a hemostat clamp. Heart and respiratory rates, and rectal temperature were recorded before and at predetermined intervals following the completion of the block. Brachial administration of LID, LIDEP or LIDXY produced forelimb analgesia within 11.3, 11.0 and 7.0 minutes, respectively. The mean duration of analgesia was 100.0 min in LID and 133.2 min in LIDEP group. The mean duration of analgesia in LIDXY group (186.8 min was significantly longer compared with LID group. In LIDEP group a significant increase in heart rate occurred 5 min after drug administration. Heart rate decreased from 35 to 80 min in sheep received LIDXY. In conclusion, the addition of xylazine to lidocaine solution for BBP provided a prolonged duration of action without any adverse effects in fat-tailed sheep.

    Full Text Available Abstract Background Whether epidural analgesia for labor prolongs the active-first and second labor stages and increases the risk of vacuum-assisted delivery is a controversial topic. Our study was conducted to answer the question: does lumbar epidural analgesia with lidocaine affect the progress of labor in our obstetric population? Method 395 healthy, nulliparous women, at term, presented in spontaneous labor with a singleton vertex presentation. These patients were randomized to receive analgesia either, epidural with bolus doses of 1% lidocaine or intravenous, with meperidine 25 to 50 mg when their cervix was dilated to 4 centimeters. The duration of the active-first and second stages of labor and the neonatal apgar scores were recorded, in each patient. The total number of vacuum-assisted and cesarean deliveries were also measured. Results 197 women were randomized to the epidural group. 198 women were randomized to the single-dose intravenous meperidine group. There was no statistical difference in rates of vacuum-assisted delivery rate. Cesarean deliveries, as a consequence of fetal bradycardia or dystocia, did not differ significantly between the groups. Differences in the duration of the active-first and the second stages of labor were not statistically significant. The number of newborns with 1-min and 5-min Apgar scores less than 7, did not differ significantly between both analgesia groups. Conclusion Epidural analgesia with 1% lidocaine does not prolong the active-first and second stages of labor and does not increase vacuum-assisted or cesarean delivery rate.

    Lidocaine is a common local anesthetic drug. 125 I-Lidocaine was prepared with labeling yield about 95%. The conditions required to obtain this yield were 50 μg substrate, 50 μg CAT, 5-10 min reaction time, ph 7 and at room temperature. Different chromatographic techniques (electrophoresis and thin layer chromatography TLC) were used to evaluate the radiochemical yield and purity of the labeled product. Biodistribution studies were carried out in normal Albino Swiss mice and the result indicate the possibility of using 125 I-Lidocaine to be used as imaging agent

    Rib fracture pain is notoriously difficult to manage. The lidocaine patch is effective in other pain scenarios with an excellent safety profile. This study assesses the efficacy of lidocaine patches for treating rib fracture pain. A prospectively gathered cohort of patients with rib fracture was retrospectively analyzed for use of lidocaine patches. Patients treated with lidocaine patches were matched to control subjects treated without patches. Subjective pain reports and narcotic use before and after patch placement, or equivalent time points for control subjects, were gathered from the chart. All patients underwent long-term follow-up, including a McGill Pain Questionnaire (MPQ). Twenty-nine patients with lidocaine patches (LP) and 29 matched control subjects (C) were analyzed. During the 24 hours before patch placement, pain scores and narcotic use were similar (LP 5.3, C 4.6, P = 0.19 and LP 51, C 32 mg morphine, P = 0.17). In the 24 hours after patch placement, LP patients had a greater decrease in pain scores (LP 1.2, C 0.0, P = 0.01) with no change in narcotic use (LP -8.4, C 0.5-mg change in morphine, P = 0.25). At 60 days, LP patients had a lower MPQ pain score (LP 7.7, C 12.2, P rib fracture pain. Lidocaine patches resulted in a sustained reduction in pain, outlasting the duration of therapy.

    Objective:To evaluate the action of 2% lidocaine on the culture results of bronchial fluid in patients suspected of having lower respiratory tract infections. Study Design:Cross-sectional analytical study. Place and Duration of Study:Shahid Sadoughi Hospital, Yazd, Iran, from November 2014 to November 2015. Methodology:Patients suspected of lower respiratory tract infections referred to bronchoscopy unit of the Hospital were included. Those with incomplete questionnaire and bronchoscopy contraindication were excluded. Bronchial fluid was aspirated before and after local application of 2% lidocaine and cultured, according to the suspected clinical diagnosis. Finally, statistical analysis was performed using SPSS software, version 17.0. For statistical comparisons, McNemar's test was used. Level of significance was kept at p <0.05. Results:The mean age of the study population was 51.83 +-15.93 with a range of 25 - 80 years. Out of 130 patients, 60 patients had positive culture results. Nineteen (31.7%) cases had positive culture for tuberculosis and 41 (63.3%) cases had positive results for other bacteria before intervention that did not change after using 2% lidocaine (p=1). In 70 (53.84%) cases, results were negative before and after use of 2% lidocaine. Conclusion:No significant difference was found between culture results before and after the use of lidocaine. Therefore, lidocaine can be used during bronchoscopy to increase patient tolerance. (author)

    Juvenile granulosa cell tumor (JGCT) of the testis is a rare benign tumor that typically presents as a relatively small (<2 cm) unilateral scrotal mass in neonates or infants. Bilateral JGCT of the testes presenting as large intraabdominal masses in the neonate is very rare. Utilizing preoperative MRI findings, we report a rare case of bilateral JGCT of the testes presenting as large multiseptated abdominal masses originating from undescended intraabdominal testes in a neonate.

    The management of acute scrotal swelling can be challenging in neonatal age, with scrotal infections being great mimickers of testicular torsion. Only a few unilateral cases of scrotal abscess have been previously reported, mostly caused by Staphylococcus and Salmonella. We describe the case of a newborn who developed bilateral scrotal abscesses caused by Klebsiella pneumoniae and discuss the rarity of the case, regarding both the bilaterality and the pathogen, never reported before.

    ELA-max (4% lidocaine) and EMLA cream (lidocaine-prilocaine 2.5%) are topicals used for superficial anesthesia. Only few studies have been published on their comparative effectiveness in close-to-practice pain models. (1) To evaluate the analgesic efficacy of lidocaine cream compared with lidocaine-prilocaine cream and placebo. (2) To assess the safety and tolerability. Randomized, three-arm, double-blind trial in 40 healthy volunteers comparing the anesthetic effects of Lidocaine and lidocaine-prilocaine cream to placebo at various time points (0-120 min). A standardized pain was induced by lancet pricks and measured by a visual analogue scale. Intra-individual comparison between the test areas was performed in a cross-over design. Lidocaine showed significantly reduced pain compared to placebo at all assessment points. Pain reduction was achieved significantly earlier using lidocaine occlusively (30 min). No significant differences were found concerning the anesthetic efficacy of lidocaine and lidocaine-prilocaine cream. There were no relevant adverse events. This study confirms that a topical preparation with 4% lidocaine is an effective and safe treatment option for superficial anesthesia. It supports the claim that an occlusive application is more rapid in action. 4% lidocaine is of value as a rapidly-acting local anesthetic for the treatment of minor surgical procedures.

    The rostral ventral tegmental area (VTAR) and central nucleus of amygdala (CeA) are considered the main regions for induction of psychological dependence on abused drugs, such as morphine. The main aim of this study was to investigate the transient inhibition of each right and left side as well as both sides of the VTAR and the CeA by lidocaine (2%) on morphine reward properties using the conditioned place preference (CPP) method. Male Wistar rats (250±20 g) 7 days after recovery from surgery and cannulation were conditioned to morphine (7.5 mg/kg) in CPP apparatus. Five minutes before morphine injection in conditioning phase, lidocaine was administered either uni- or bilaterally into the VTAR (0.25 μL/site) or CeA (0.5 μL/site). The results revealed that lidocaine administration into the left side, but not the right side of the VTAR and the CeA reduced morphine CPP significantly. The reduction was potentiated when lidocaine was injected into both sides of the VTAR and the CeA. The number of compartment crossings was reduced when lidocaine was injected into both sides of the VTAR and the CeA as well as the left side. Rearing was reduced when lidocaine was injected into the right, but not the left side of the VTAR. Sniffing and rearing increased when animals received lidocaine in the right side and reduced in the group that received lidocaine in the left side of the CeA. It was concluded that the right and the left side of VTAR and the CeA play different roles in morphine-induced activity and reward. © 2016 John Wiley & Sons Australia, Ltd.

    Current pain assessment and management in neonates need to be fully described before neonatal pain care can be optimized. This study's purpose was to report neonatal nurses' knowledge, existing pain assessment practice, and pharmacological pain management of neonates in Jordan. A cross-sectional descriptive study was conducted. Eighteen neonatal intensive care units in Jordan were included in the study. One hundred eighty-four neonatal nurses participated. Questionnaires were distributed by and returned to the neonatal intensive care units' managers between June and August 2014. Descriptive and inferential statistics were used to present study results. Of 240 questionnaires distributed, 184 useable responses were returned. Nurses' knowledge regarding neonates' neurological development, nociception, and need for neonatal pain management was suboptimal. The analgesics most commonly used to treat neonatal pain were acetaminophen (52%) and lidocaine (45%). Benzodiazepines, phenobarbitone, and muscles relaxants were also used. Most nurses (54%-97%) reported that pain emanating from most painful procedures was never or rarely treated. Circumcision, lumbar punctures, and chest tube insertion were assigned the highest pain scores (≥9), but were rarely accompanied by analgesia. Pain assessment scales were more likely to be used, and procedural pain was more likely to be treated, in private hospitals than public hospitals. Neonates who require special care still suffer unnecessary pain that could be avoided and managed by following best practice recommendations. Disparities between developed and developing countries in quality of neonatal pain care appear to exist. Resources for education and routine care are needed to address these discrepancies.

The heart rate, blood pressure, the change of oxygen saturation, pain, and the occurrence of abortion syndrome before and after operation between the two groups were compared.Results:The fineness rates of analgesia and anesthesia evaluation in the observation group were significantly higher than those in the control group (P0.05). The postoperative heart rate and blood pressure in the control group were significantly lower than those before operation and in the observation group with a slow recovery (P0.05). The occurrence rate of abortion syndrome in the observation group was significantly lower than that in the control group (P<0.05). Conclusions:Application of lidocaine in the induced abortion can relieve the pain and reduce the occurrence rate of abortion syndrome with a simple and safe operation; therefore, it deserves to be widely recommended.

    2004-12-09

    In relieving local pains, lidocaine, one of ester type local anesthetics, has been used. To develop the lidocaine gels of enhanced local anesthetic effects, hydroxypropyl methylcellulose (HPMC) based bioadhesive polymer gel containing an enhancer was formulated. As the drug concentration in the gels increased up to 3%, the permeation rate of drug linearly increased, thereafter reaching a plateau. As the temperature of surrounding solutions increased, the permeation of drug increased. The activation energy of drug permeation was 3.29 kcal/mol for lidocaine. The permeation rate of drug through skin was studied using various enhancers, such as glycols, non-ionic surfactants, and bile salts. Among the enhancers studied, diethylene glycol showed the greatest enhancing effects on drug permeation through skin. The analgesic activity was examined using a tail-flick analgesimeter. In the area under the efficacy curve (AUEC) of the rat-tail flick tests, lidocaine gel containing diethylene glycol showed about 3.89-fold increase in analgesic activity compared with the control. The addition of vasoconstrictor in the gels prolonged the analgesic effects. The result of this study supports that the bioadhesive gel with efficient anesthetic effect could be developed using HPMC with combination of enhancer and vasoconstrictor.

    In order to compare the efficacy of lidocaine and articaine for pain control during third molar surgery, 160 patients presenting bilateral asymptomatic impacted mandibular third molars were selected. They received 1.8 mL of 2% lidocaine with epinephrine 1:100,000 during inferior alveolar nerve block. In group 1 (n = 80), an infiltrative injection of 0.9 mL of 2% lidocaine with epinephrine 1:100,000 was performed in buccal-distal mucosa of the third molar. Group 2 (n = 80) received 0.9 mL of 4% articaine with epinephrine 1:100,000 in the contralateral side. All procedures were performed at the same visit, by a single operator, in a double-blind and parallel design. The duration of each surgery and the moment when the patient expressed pain were noted. Data were analyzed by nonpaired t test and chi-square test (alpha = 5%). Duration of surgery did not differ (p = .83) between Groups 1 (19.8 ± 2.3 minutes) and 2 (19.7 ± 3.0 minutes). Pain was expressed more in group 1 (26.3%) than in group 2 (10%) (odds ratio = 3.2, p = .0138).

    The pharmacokinetics of lidocaine were studied in nonpregnant and pregnant ewes. The maternal femoral vessels were cannulated and, on the day of study, the urinary bladder was catheterized. Lidocaine HCl, 4-5 mg/kg, was administered by IV injection over 60 seconds. Serial samples of arterial blood and urine were collected over 4 hours, and drug concentrations were determined using a gas chromatographic technique. The volume of the central compartment was greater in pregnant than in nonpregnant ewes (1.51 +/- 0.20 vs. 0.96 +/- 0.16 L/kg) as was the volume of distribution at steady state (Vdss): 3.24 +/- 0.40 vs. 1.88 +/- 0.32 L/kg. The volume of distribution during the terminal exponential phase of drug elimination (Vd beta) and total clearance of lidocaine (Cl) were also higher in pregnant animals: 4.17 +/- 0.50 L/kg and 99.6 +/- 8.5 ml.min-1.kg-1, respectively; compared to 2.46 +/- 0.48 L/kg and 44.1 +/- 6.5 ml.min-1.kg-1, in nonpregnant ewes. However, the balance between these changes in Vd beta and Cl did not result in a significant difference in the elimination half-life of lidocaine (38.1 +/- 2.1 minutes in nonpregnant and 31.9 +/- 3.0 minutes in pregnant ewes). If these data are applicable to humans, the risk of drug accumulation after repeated administration of lidocaine is no greater in pregnant than in nonpregnant patients.

    Neonatal hypertension (HT) is a frequently under reported condition and is seen uncommonly in the intensive care unit. Neonatal HT has defined arbitrarily as blood pressure more than 2 standard deviations above the base as per the age or defined as systolic BP more than 95% for infants of similar size, gestational age and postnatal age. It has been diagnosed long back but still is the least studied field in neonatology. There is still lack of universally accepted normotensive data for neonates as per gestational age, weight and post-natal age. Neonatal HT is an important morbidity that needs timely detection and appropriate management, as it can lead to devastating short-term effect on various organs and also poor long-term adverse outcomes. There is no consensus yet about the treatment guidelines and majority of treatment protocols are based on the expert opinion. Neonate with HT should be evaluated in detail starting from antenatal, perinatal, post-natal history, and drug intake by neonate and mother. This review article covers multiple aspects of neonatal hypertension like definition, normotensive data, various etiologies and methods of BP measurement, clinical features, diagnosis and management.

    Full Text Available Introduction: Pain control is essential to the behavioral management of children in pediatric dentistry. Effective anesthesia plays a key role in this regard, especially in pulp therapy. In order to achieve successful anesthesia, the type of analgesics and injection techniques should be considered. The present study aimed to compare the anesthetic efficacy of articaine infiltration and lidocaine inferior alveolar nerve block in the pulp therapy of lower primary molars. Materials and Methods: This randomized, crossover, triple-blind clinical trial was conducted on 64 children aged 4-10 years, who required the bilateral pulp therapy of the lower primary molars. Subjects were randomly divided into two groups. Treatment was performed for two sessions, and one lower primary molar was treated in each session. In the first treatment session, subjects in group A were injected with lidocaine inferior alveolar nerve block, and in the second session, they were injected with articaine infiltration. In group B, all the procedures were similar to group A. In the first treatment session, subjects in group B were injected with articaine infiltration, and in the second session, they were injected with lidocaine inferior alveolar nerve block. Pain intensity was measured upon the initiation of the pulp exposure using the visual analogue scale (VAS. Data analysis was performed by crossover analysis, paired t-test, and independent two-sample t-test. Results: During the study period, mean pain intensity in the children treated by lidocaine inferior alveolar nerve block was significantly lower compared to those treated by articaine infiltration. However, the two techniques had no statistically significant difference in the children aged 4-6 years and the treatment of the first primary molars. Conclusion: According to the results, lidocaine inferior alveolar nerve block has higher anesthetic efficacy in the pulp therapy of the lower primary molars compared to articaine

    Incontinentia Pigmenti is an X-linked dominant neurocutaneous disorder with central nervous system manifestations in 30% of cases, including seizures and mental retardation. Ischemic or hemorrhagic cerebrovascular accidents have been reported rarely in incontinentia pigmenti. Chart review and literature search was performed following identification of the index case. We describe a patient with incontinentia pigmenti who developed bilateral cerebrovascular accidents in the neonatal period, with resultant severe neurologic sequelae. This is the second reported case of bilateral cerebrovascular accidents in a patient with incontinentia pigmenti. This finding may be secondary to cerebrovascular anomalies, similar to those observed in the retina. Recognition of cerebrovascular accidents as a complication of incontinentia pigmenti will hopefully lead to earlier recognition and treatment.

  3. [Bilateral cochlear implants].

    Cochlear implants (CI) are standard for the hearing rehabilitation of severe to profound deafness. Nowadays, if bilaterally indicated, bilateral implantation is usually recommended (in accordance with German guidelines). Bilateral implantation enables better speech discrimination in quiet and in noise, and restores directional and spatial hearing. Children with bilateral CI are able to undergo hearing-based hearing and speech development. Within the scope of their individual possibilities, bilaterally implanted children develop faster than children with unilateral CI and attain, e.g., a larger vocabulary within a certain time interval. Only bilateral implantation allows "binaural hearing," with all the benefits that people with normal hearing profit from, namely: better speech discrimination in quiet and in noise, as well as directional and spatial hearing. Naturally, the developments take time. Binaural CI users benefit from the same effects as normal hearing persons: head shadow effect, squelch effect, and summation and redundancy effects. Sequential CI fitting is not necessarily disadvantageous-both simultaneously and sequentially fitted patients benefit in a similar way. For children, earliest possible fitting and shortest possible interval between the two surgeries seems to positively influence the outcome if bilateral CI are indicated.

    Full Text Available The effect of local anesthetic composed of lidocaine and epinephrine on vesiculability of blood cells and erythrocyte shape was studied. Whole blood and plasma were incubated with lidocaine/epinephrine. Extracellular vesicles were isolated by centrifugation and washing and counted by flow cytometry. Lidocaine/epinephrine and each component alone were added to diluted blood. Shape changes were recorded by micrographs. An ensemble of captured frames was analyzed for populations of discocytes, echinocytes, and stomatocytes by using statistical methods. Incubation of whole blood and blood plasma with lidocaine/epinephrine considerably increased concentration of extracellular vesicles in isolates (for an average factor 3.4 in blood and 2.8 in plasma. Lidocaine/epinephrine caused change of erythrocyte shape from mainly discocytic to mainly stomatocytic (higher than 50%. Lidocaine alone had even stronger stomatocytic effect (the percent of stomatocytes was higher than 95% while epinephrine had echinocytic effect (the percent of echinocytes was higher than 80%. The differences were highly statistically significant p<10-8 with statistical power P=1. Lidocaine/epinephrine induced regions of highly anisotropically curved regions indicating that lidocaine and epinephrine interact with erythrocyte membrane. It was concluded that lidocaine/epinephrine interacts with cell membranes and increases vesiculability of blood cells in vitro.

    2018-03-14

    Lidocaine, an amide anesthetic, has been used in the treatment of a wide variety of pain disorders for over 75 years. In addition to pain control, lidocaine is an anti-arrhythmic agent and has anti-inflammatory properties. Lidocaine's unique properties, including nonlinear pharmacokinetics, have limited its modern-day use. The purpose of this review is to offer a better understanding of the properties of this unique treatment, which we hope will allow more practitioners to offer this to their patients. An analysis of the history, pharmacokinetics, and relevant uses of lidocaine in headache medicine based on a synthesis of the medical literature and clinical experience. Lidocaine is an amide anesthetic that inhibits voltage gated sodium channels, and lidocaine metabolism occurs exclusively in the liver. One lidocaine metabolite has its own unique properties and may be an active form of the drug. Open label and retrospective studies have investigated the use of lidocaine in many headache disorders, primarily via injection or infusion. Further research into the active metabolite of lidocaine may allow for its use as a novel nonopiate treatment of chronic pain. © 2018 American Headache Society.

    Full Text Available Introduction Choanal atresia (CA is a challenging surgical problem defined as a failure in the development of communication between the nasal cavity and nasopharynx. Objective The objective of this study is to describe computed tomography (CT findings in cases with bilateral choanal atresia. Methods The study involved performing axial and coronal non-contrast CT scanning with 2–3 mm sections on14 neonates that had bilateral CA. We used fiberoptic nasal endoscopy to confirm the diagnosis. We evaluated coronal CT to study the skull base area in such neonates. Results This study included 14 neonates with bilateral CA; with mean age of 7 ± 3.5 days. Mixed atretic plates were found in 12 (85.7% cases while two (14.3% had pure bony atresia. Isolated CA was detected in 9 cases (64.3% and 5 (35.7% cases had associated anomalies. Coronal CT showed soft tissue density in the nasal cavity that appeared to extend through an apparent defect in the nasal roof (cribriform plate, falsely diagnosed by radiologists as associated encephalocele. At the time of surgical repair, all patients showed thick tenacious mucous secretions in both nasal cavities and revealed no encephalocele. Nasal roof remained intact in all cases. Conclusion The thick secretion of bilateral CA could give a false encephalocele appearance on the CT. It is highly recommended to perform proper suction of the nasal cavity of suspected CA cases just before CT scanning.

    OBJECTIVE To determine effects of fentanyl, lidocaine, and a fentanyl-lidocaine combination on the minimum alveolar concentration of sevoflurane preventing motor movement (MAC NM ) in dogs. ANIMALS 6 adult Beagles. PROCEDURES Dogs were anesthetized with sevoflurane in oxygen 3 times (1-week intervals). Baseline MAC NM (MAC NM-B ) was determined starting 45 minutes after induction of anesthesia. Dogs then received 1 of 3 treatments IV: fentanyl (loading dose, 15 μg/kg; constant rate infusion [CRI], 6 μg/kg/h), lidocaine (loading dose, 2 mg/kg; CRI, 6 mg/kg/h), and the fentanyl-lidocaine combination at the same doses. Determination of treatment MAC NM (MAC NM-T ) was initiated 90 minutes after start of the CRI. Venous blood samples were collected at the time of each treatment MAC NM measurement for determination of plasma concentrations of fentanyl and lidocaine. RESULTS Mean ± SEM overall MAC NM-B for the 3 treatments was 2.70 ± 0.27 vol%. The MAC NM decreased from MAC NM-B to MAC NM-T by 39%, 21%, and 55% for fentanyl, lidocaine, and the fentanyl-lidocaine combination, respectively. This decrease differed significantly among treatments. Plasma fentanyl concentration was 3.25 and 2.94 ng/mL for fentanyl and the fentanyl-lidocaine combination, respectively. Plasma lidocaine concentration was 2,570 and 2,417 ng/mL for lidocaine and the fentanyl-lidocaine combination, respectively. Plasma fentanyl and lidocaine concentrations did not differ significantly between fentanyl and the fentanyl-lidocaine combination or between lidocaine and the fentanyl-lidocaine combination. CONCLUSIONS AND CLINICAL RELEVANCE CRIs of fentanyl, lidocaine, and the fentanyl-lidocaine combination at the doses used were associated with clinically important and significant decreases in the MAC NM of sevoflurane in dogs.

    Full Text Available Background: End stage renal disease (ESRD patients on maintenance hemodialysis undergo arterio-venous fistula (AVF cannulation prior to each hemodialysis session for blood access. Prior to cannulation lidocaine infiltration is done, which is often perceived as painful. Eutectic mixture of local anesthetic (EMLA has been found to significantly reduce pain associated with radial artery cannulation compared with lidocaine infiltration. Aims: To evaluate the efficacy of EMLA compared to infiltration of lidocaine in hemodialysis patients for AVF cannulation. Materials and Methods: A single-centre, crossover study of patients with an AVF on regular maintenance hemodialysis was performed in the dialysis unit of a tertiary care teaching hospital. The site of AVF, number of attempts for AVF cannulation and cannula insertion time were recorded. The patients were asked about the acceptability of application of the anesthetic, delay between anesthetic and cannulation and to score the pain on cannulation. Results: Fifty patients were included in the study. With the visual analog scale, pain score on infiltration was 4.8. Pain score on cannulation after topical application was 2.9 and after infiltration, 2.0. The number of attempts for cannulation and the cannula insertion time were similar. Anesthesia was more stressful in the injectable group rather than the topical group (P < 0.001. Delay between anesthetic and cannulation was unacceptable in the topical group (P < 0.001. Patient compliance was better during infiltration compared to topical (P < 0.005. Mean pain score during infiltration of anesthetic was significantly higher than cannulation pain after either anesthetic, although pain on cannulation was higher in the topical group (P < 0.001. Conclusions: EMLA offers a suitable alternative to lidocaine infiltration for patients using AVF for blood access.

    Paediatric and particularly neonatal neurosonography still remains a mainstay of imaging the neonatal brain. It can be performed at the bedside without any need for sedation or specific monitoring. There are a number of neurologic conditions that significantly influence morbidity and mortality in neonates and infants related to the brain and the spinal cord; most of them can be addressed by ultrasonography (US). However, with the introduction of first CT and then MRI, neonatal neurosonography is increasingly considered just a basic first line technique that offers only orienting information and does not deliver much relevant information. This is partially caused by inferior US performance – either by restricted availability of modern equipment or by lack of specialized expertise in performing and reading neurosonographic scans. This essay tries to highlight the value and potential of US in the neonatal brain and briefly touching also on the spinal cord imaging. The common pathologies and their US appearance as well as typical indication and applications of neurosonography are listed. The review aims at encouraging paediatric radiologists to reorient there imaging algorithms and skills towards the potential of modern neurosonography, particularly in the view of efficacy, considering growing economic pressure, and the low invasiveness as well as the good availability of US that can easily be repeated any time at the bedside.

    Effective management of procedural and postoperative pain in neonates is required to minimize acute physiological and behavioral distress and may also improve acute and long-term outcomes. Painful stimuli activate nociceptive pathways, from the periphery to the cortex, in neonates and behavioral responses form the basis for validated pain assessment tools. However, there is an increasing awareness of the need to not only reduce acute behavioral responses to pain in neonates, but also to protect the developing nervous system from persistent sensitization of pain pathways and potential damaging effects of altered neural activity on central nervous system development. Analgesic requirements are influenced by age-related changes in both pharmacokinetic and pharmacodynamic response, and increasing data are available to guide safe and effective dosing with opioids and paracetamol. Regional analgesic techniques provide effective perioperative analgesia, but higher complication rates in neonates emphasize the importance of monitoring and choice of the most appropriate drug and dose. There have been significant improvements in the understanding and management of neonatal pain, but additional research evidence will further reduce the need to extrapolate data from older age groups. Translation into improved clinical care will continue to depend on an integrated approach to implementation that encompasses assessment and titration against individual response, education and training, and audit and feedback.

    Cervical radiculopathy is a mixed pain syndrome characterized by neuropathic, skeletal and myofascial pain. This condition is frequently found in developed countries and is a significant source of disability and a reason for frequent medical consultation. In our Pain Therapy Centre, cervical radiculopathy is initially treated with bi-weekly cycles of mesotherapy coupled, at least 15 days later, with physiotherapy to reach the complete mobilization of cervical spine. Cervical radiculopathy is a localized neuro-pathic pain and in agreement with international guidelines, we checked if patients treated topically with 5% lidocaine medicated plaster may benefit in improving pain management and in reducing the time necessary to start physiotherapy. A retrospective study was carried out on 60 patients, of which 30 were treated with mesotherapy and 30 were treated with 5% lidocaine medicated plaster. Data for a total of 30 days observation were collected from the patient medical records. In particular, besides medical history, intensity of pain, intensity of allodynia and pain were considered. For all analyzed parameters, both treatments were effective, but patients treated with 5% lidocaine medicated plaster showed faster control of the painful symptoms, an essential condition for an earlier rehabilitative treatment.

    To compare spinal procaine to spinal lidocaine with regard to their main clinical characteristics and incidence of transient radicular irritation (TRI). In this randomized, double-blind, prospective study, patients (two groups, n=30 each) received either 100 mg of lidocaine 5% in 7.5% glucose (Group L) or 100 mg of procaine 10% diluted with 1 ml cerebrospinal fluid (Group P). After spinal anesthesia, segmental level of sensory block was assessed by pinprick. Blood pressure and the height of the block were noted each minute for the first ten minutes, then every three minutes for the next 35 min and finally every five minutes until regression of the block to L4. Motor blockade was evaluated using the Bromage scale. To evaluate the presence of TRI, each patient was questioned 48 hr after surgery. Time to highest sensory level and to maximum number of segments blocked showed no difference between groups. Mean time for sensory regression to T10 and for regression of the motor block were shorter in Group P. Eighty minutes following injection, sensory levels were lower in Group P. Five patients had inadequate surgical anesthesia in Group P and only one in Group L. No patient in Group P had TRI (95% CI 10-12%) while eight (27%) in Group L did (95% CI 12-46%). Procaine 10% was associated with a clinical failure rate of 14.2%. This characteristic must be balanced against an absence of TRI, which occurs more frequently with the use of lidocaine 5%.

    Interaction between local anesthetic solution, lidocaine hydrochloride (with and without adrenaline), and root canal irrigants such as sodium hypochlorite (NaOCl), ethylene diamine tetra-acetic acid (EDTA), and chlorhexidine (CHX) has not been studied earlier. Hence, the purpose of this in vitro study was to evaluate the chemical interaction between 2% lidocaine hydrochloride (with and without adrenaline) and commonly used root canal irrigants, NaOCl, EDTA, and CHX. SAMPLES WERE DIVIDED INTO EIGHT EXPERIMENTAL GROUPS: Group I-Lidocaine hydrochloride (with adrenaline)/3% NaOCl, Group II-Lidocaine hydrochloride (with adrenaline)/17% EDTA, Group III- Lidocaine hydrochloride (with adrenaline)/2% CHX, Group IV-Lidocaine hydrochloride (without adrenaline)/3% NaOCl, Group V-Lidocaine hydrochloride (without adrenaline)/17% EDTA, Group VI-Lidocaine hydrochloride (without adrenaline)/2% CHX, and two control groups: Group VII-Lidocaine hydrochloride (with adrenaline)/deionized water and Group VIII-Lidocaine hydrochloride (without adrenaline)/deionized water. The respective solutions of various groups were mixed in equal proportions (1 ml each) and observed for precipitate formation. Chemical composition of the formed precipitate was then analysed by nuclear magnetic resonance spectroscopy (NMR) and confirmed with diazotation test. In groups I and IV, a white precipitate was observed in all the samples on mixing the respective solutions, which showed a color change to reddish brown after 15 minutes. This precipitate was then analysed by NMR spectroscopy and was observed to be 2,6-xylidine, a reported toxic compound. The experimental groups II, III, V, and VI and control groups VII and VIII showed no precipitate formation in any of the respective samples, until 2 hours. Interaction between lidocaine hydrochloride (with and without adrenaline) and NaOCl showed precipitate formation containing 2,6-xylidine, a toxic compound.

    Liposomes are microscopic phospholipid vessels that have been utilized to extend the action of topical medications. Previous studies have demonstrated that liposomal vehicles can prolong the action of a variety of medications, including antifungals, anesthetics, interferon, and antineoplastic agents. The purpose of this study was to examine the degree and duration of anesthesia produced by lidocaine in a liposomal vehicle compared with lidocaine in a nonliposomal vehicle and compared with EMLA. The topical preparations in this study were allowed to contact the skin for a 30-minute period prior to evaluation of anesthetic effectiveness. Unoccluded and Tegaderm-occluded topical preparations were evaluated in two separate arms of the study. Thirteen healthy volunteers (three male, 10 female) were recruited for the nonocclusion arm of the study. Six healthy volunteers (two male, four female) were recruited for the occlusion arm of the study. Subjects with a history of allergy to lidocaine, a history of seizures, cardiac or respiratory difficulty, pregnant patients, and patients less than 18 years old were excluded. Written informed consent was obtained from all patients prior to testing. The volar forearms of the volunteers were swabbed with isopropyl alcohol and allowed to dry. A template was then utilized to mark 2 x 2-cm squares with a skin marker on both volar forearms. In total, nine squares corresponding to nine test areas were marked. The nine test preparations were applied to the test areas in a double-blinded fashion using a clean swab stick. The test preparations were then allowed to remain on the skin for 30 minutes in either occluded or nonoccluded from depending upon the arm of the study. Following the 30-minute application period, the test preparations were wiped off with clean gauze. Testing for anesthesia was performed by following a previously published method utilizing gentle pinpricks. A new pinprick apparatus was used for each patient. Pinprick

    We evaluate 311 breast cancer patients admitted to Yong Dong Severance Hospital Between October 1st 1985 and July 31th 1989, and were able to obtain the following conclusions. 1) There were 14(4.5%) bilateral breast cancers among the 311 confirmed breast cancers. 2) Among the bilateral breast cancers, 5(31%) were synchronous and 9(69%) metachronous. 3) Average interval between the first and the second breast cancer in metachronous cancers was 3.8 year(1-15 years). 4) Bilateral breast cancer was most prevalent in the fifth decade (6/14) with the mean age of 47 years. 5) Film mammogram and sonomammogram showed findings of typical breast malignancies. There was no additional specific findings for each cancer in bilateral breast cancers which was different from unilateral cancers. Therefor, in the patients with unilateral breast cancer, possibility of the second lesion in the contralateral side must be considered and a close follow up observation should be done for at least 3 years

    The effect of temperature on the antibacterial activity of lidocaine to Staphylococcus aureus and Pseudomonas aeruginosa was investigated in vitro. At 10 C at which S. aureus organisms do not grow and might be metabolically inactive, the antibacterial activity of lidocaine to S. aureus was not observed in a concentration of 1%, which was quite antibacterial to S. aureus at 37 C. On the other hand, at 40 C a conspicuously increased antibacterial activity to S. aureus of lidocaine was observed in a concentration of 0.25% which was not antibacterial to S. aureus organisms at 37 C. Similar results were obtained when P. aeruginosa organisms were examined in place of S. aureus, although P. aeruginosa was found to be less susceptible to lidocaine than S. aureus. The clinical significance of the thermal effect on the antibacterial activity of lidocaine was discussed in brief.

    We examined the effects of local anesthetics lidocaine and procaine on glutamatergic spontaneous excitatory transmission in substantia gelatinosa (SG) neurons in adult rat spinal cord slices with whole-cell patch-clamp techniques. Bath-applied lidocaine (1-5 mM) dose-dependently and reversibly increased the frequency but not the amplitude of spontaneous excitatory postsynaptic current (sEPSC) in SG neurons. Lidocaine activity was unaffected by the Na + -channel blocker, tetrodotoxin, and the TRPV1 antagonist, capsazepine, but was inhibited by the TRP antagonist, ruthenium red. In the same neuron, the TRPA1 agonist, allyl isothiocyanate, and lidocaine both increased sEPSC frequency. In contrast, procaine did not produce presynaptic enhancement. These results indicate that lidocaine activates TRPA1 in nerve terminals presynaptic to SG neurons to increase the spontaneous release of L-glutamate.

    The present study investigated the effects of different doses of intrathecal lidocaine on established thermal hyperalgesia and tactile allodynia in the chronic constriction injury model of neuropathic pain, defined the effective drug dose range, the duration of pain-relief effects, and the influence of this treatment on the body and tissues. Male Sprague-Dawley rats were divided into five groups and received intrathecal saline or lidocaine (2, 6.5, 15, and 35 mg/kg) 7 days after loose sciatic ligation. Respiratory depression and hemodynamic instability were found to become more severe as doses of lidocaine increased during intrathecal therapy. Two animals in the group receiving 35 mg/kg lidocaine developed pulmonary oedema and died. Behavioral tests indicated that 6.5, 15, and 35 mg/kg intrathecal lidocaine showed different degrees of reversal of thermal hyperalgesia, and lasted for 2-8 days, while 2 mg/kg lidocaine did not. The inhibition of tactile allodynia was only observed in rats receiving 15 and 35 mg/kg lidocaine, and the anti-allodynic effects were identical in these two groups. Histopathologic examinations on the spinal cords revealed mild changes in rats receiving 2-15 mg/kg lidocaine. However, lesions were severe after administration of 35 mg/kg lidocaine. These findings indicate that intrathecal lidocaine has prolonged therapeutic effects on established neuropathic pain. The balance between sympathetic and parasympathetic nervous activities could be well preserved in most cases, except for 35 mg/kg. Considering the ratio between useful effects and side effects, doses of 15 mg/kg are suitable for intrathecal injection for relief of neuropathic pain.

    The combination of tribenoside+lidocaine (Procto-Glyvenol®) is a medical preparation for the local treatment of hemorrhoids, delivered as a suppository or rectal cream. This product has been used for decades in the therapy of hemorrhoids. This review discusses available evidence on the use of tribenoside/lidocaine in clinical practice. Papers were retrieved by a PubMed search, using different combinations of pertinent keywords (e.g. tribenoside AND hemorrhoids), without any limitations in terms of publication date and language. Documents from Authors' personal collection of literature could also be considered. Papers were selected for inclusion according to their relevance for the topic, as judged by the Authors. The efficacy of the combination of tribenoside+lidocaine in relieving symptoms caused by hemorrhoids and its safety have been assessed in several clinical studies on patients of either gender, either versus its two individual components (tribenoside and lidocaine) or versus steroids in the same setting. Five studies compared the combination treatment with each of its single components, and of these, three studies compared tribenoside+ lidocaine with a tribenoside-free semi-placebo preparation containing only lidocaine, and two studies compared this combination with lidocaine-free preparations containing only tribenoside. Tribenoside+lidocaine was compared with steroid-containing preparations in six studies. Last, two studies evaluated the efficacy and tolerability of the tribenoside+lidocaine combination in women with hemorrhoids as a consequence of pregnancy or delivery. All the above-mentioned studies were well-conducted and can provide a comprehensive evaluation of tribenoside+lidocaine in the treatment of hemorrhoids. Enough evidence exists to recommend the use of this combination therapy as a fast, effective and safe option for the local treatment of low-grade hemorrhoids.

    This prospective, randomized, double-blind study aimed to compare the efficacy of lidocaine with epinephrine versus lidocaine with clonidine for inferior alveolar nerve block (IANB) and hemodynamic stability (heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure) in patients with irreversible pulpitis. One hundred patients with irreversible pulpitis in mandibular molar teeth randomly received 1.8 mL of 2% lidocaine with clonidine (15 μg mL -1 ) or 1.8 mL of 2% lidocaine with epinephrine (12.5 μg mL -1 ), using a conventional IANB technique. Endodontic access cavities were prepared 15 min after solution deposition, and all patients were required to have profound lip numbness. Success was defined as no or mild pain (visual analog scale recording) upon endodontic access cavity preparation or initial canal instrumentation. The hemodynamic parameters were measured before, during and 5, 10 and 30 min after administration. Finally, the collected data were subjected to independent t-test, chi-square and Fisher's exact test using spss software ver.20 at a significant level of 0.05. The success rates for IANB using lidocaine with epinephrine and lidocaine with clonidine solutions were 29% and 59%, respectively. The clonidine group exhibited a significantly higher success rate (P < 0.05). Five minutes after drug administration, systolic blood pressure and heart rate significantly increased in the lidocaine with epinephrine group and insignificantly decreased in lidocaine with clonidine group. For mandibular molars with irreversible pulpitis, addition of clonidine to lidocaine improved the success rate of IANB compared to a standard lidocaine/epinephrine solution. © 2016 International Endodontic Journal.

    Despite several shortcomings, MS222 is the most commonly used chemical agent for euthanasia of zebrafish. Although lidocaine hydrochloride has some advantages over MS222, its effectiveness as a euthanasia agent for zebrafish is unknown. Larvae at 9 to 16 d postfertilization were exposed to 250 mg/L MS222 or 400, 500, 600, 700, 800, 900, or 1000 mg/L lidocaine and observed for cessation of heartbeat. Adult zebrafish were exposed to 250 mg/L MS222 or 400, 500, or 600 mg/L lidocaine; times to loss of righting reflex, cessation of opercular movement, and complete recovery; body length; aversive behavior; and gross and microscopic evidence of acute toxicity were evaluated. The heartbeat was not lost from any larvae in any group, regardless of drug or dosage. For adults, time to loss of righting reflex was greatest in the 500-mg/L lidocaine group. Opercular movement ceased earlier in all lidocaine groups compared with the MS222 group. Fish in the 500-mg/L lidocaine group were smaller than those in other groups. Fewer fish in the lidocaine groups displayed aversive behavior (erratic swimming and piping) compared with the MS222 group. No fish in the lidocaine hydrochloride groups (n = 30) recovered from euthanasia, whereas one fish in the MS222 group did (n = 10). Neither the MS222 nor lidocaine groups showed any gross or histologic changes suggestive of acute toxicity. Our results suggest that lidocaine hydrochloride may be an effective alternative chemical euthanasia agent for adult zebrafish but should not be used in larval fish. PMID:27931323

    We aimed to compare antinociceptive effects of IV infusions of morphine (M), morphine-lidocaine (ML), or morphine-lidocaine-ketamine (MLK) combined, in a mild-to-moderate pain model in dogs. Eighteen adult hounds were heavily sedated with IV morphine (0.2 mg/kg) and dexmedetomidine to undergo thoracic skin incisions. After reversal, dogs were randomly assigned to receive loading doses of lidocaine and ketamine (MLK), lidocaine and saline (ML), or equivalent volume of saline (M), followed by 18 hr constant infusions of morphine (0.12 mg/kg/hr), lidocaine (3 mg/kg/hr) and ketamine (0.6 mg/kg/hr); morphine (0.12 mg/kg/hr) and lidocaine (3 mg/kg/hr); or morphine (0.12 mg/kg/hr), respectively. Pain was assessed with Short Form Glasgow Composite Measure Pain Scale and mechanical nociception with von Frey filaments (VFFS). Data were analyzed with linear mixed model on ranks. Independently of treatment, Short Form Glasgow Composite Measure Pain Scale was significantly higher than baseline for 24 hr (p < .0001), while VFFS was significantly lower than baseline for 48 hr post-recovery (p < .0001), with no difference between MLK and M groups. The ML group recorded significantly lower VFFS (p = .02) than the M group for the entire study. In conclusion, there was no significant analgesic difference between MLK and M alone.

    To compare the effects of 10% dextran and epinephrine on intraosseous injection with lidocaine in rabbits. Twenty male Japanese white rabbits were used. The effect of intraosseous injection was evaluated using an electromyogram (EMG) of the digastric muscle after electrical pulp stimulation. Two percent lidocaine alone (L), 2% lidocaine containing 1:80000 epinephrine (LE8), 2% lidocaine containing 1:160 000 epinephrine (LE16), and 2% lidocaine containing 10% dextran (LD) were tested. Electromyogram recordings were repeated before and 30 seconds, 1, 2, 3, 4, 5, 7, 10, 12, 15, and 20 minutes after the intraosseous injection. Thereafter, recordings were repeated every 5 minutes until the EMG recovered to the control value. There was no difference in the onset time between the 4 groups. The order of the duration of maximum effect was LE8 >LE16 = LD >or=L. The order of the duration of anesthesia was LE8 >LE16 = LD >L. Ten percent dextran potentiates local anesthetic effects of 2% lidocaine in intraosseous injection. The potency of 10% dextran is comparable to 1:160 000 epinephrine.

    Conclusion: In clinical practice, we recommend that patient should be informed about the possibility of recurrence of an adverse reaction in case of re-exposure to lidocaine, even in the vast majority of cases where true allergy could not be proven. In case of further need for local anesthesia with history of an adverse event, a different agent may be chosen even from the same class (another amide as cross-reactions in the amide group are rare. Otherwise, an anesthetic from the ester group can also be safely used.

    • BACKGROUND: Magnesium (Mg has been used as an adjuvant medication in postoperative analgesia. We planed this study to assess the effects of Mg, when added to lidocaine in intravenous regional anesthesia (IVRA on the tourniquet pain.
    • METHODS: Forty patients undertaking hand surgery were randomly allocated into 2 groups to be given IVRA. They received 20 ml lidocaine 1% diluted with 20 ml saline to a total of 40 ml in the group L (n = 20 or 7.5 ml magnesium sulfate 20% plus 20 ml lidocaine 1% diluted with 12.5 ml saline to a total of 40 ml in the group M (n = 20. Sensory and motor block onset and recovery times, anesthesia and operation qualities were recorded. Before and after the tourniquet use at 5, 10, 15, 20, 30, 40, and 50 minutes, hemodynamic variables, tourniquet pain, and analgesic use were noted. Subsequent to the tourniquet deflation, at 6, 12, and 24 hours, hemodynamic variables, pain, time to first analgesic requirement, analgesic use and side effects were recorded.
    • RESULTS: Shortened sensory and motor block onset times were established in group M (P < 0.05. Visual analog scale (VAS scores were less in group M at 20, 30, 40, and 50 minutes after tourniquet inflation (P < 0.05. Intraoperative, analgesic requirement was less in group M (P < 0.05. Anesthesia excellence, as determined by the anesthesiologist and surgeon, was significantly better in group M (P < 0.05. Time to the first analgesic requirement in group M was 53.75 ± 6.94 minutes and in group L was 40.76 ± 14.55 minutes (P < 0.05. Postoperative VAS scores were higher at 6, 12, and 24 hours in group L (P < 0.05.
    • CONCLUSIONS: Adding Mg to lidocaine for IVRA enhanced the quality of anesthesia and analgesia without causing side effects.

    OBJECTIVE: To warn pediatricians about the early recognition of cholestasis in newborns and infants. METHODS: A bibliographic research about cholestasis was performed using Medline, and emphasizing the most relevant publications of the last 30 years. RESULTS: The concept of cholestasis and the causes of cholestatic tendency in newborns and infants are described. Several causes of intra and extrahepatic cholestasis are reported as well. In this review, only the diseases with diagnostic, therapeutic or prognostic peculiarities are commented, including extrahepatic biliary atresia, idiopathic neonatal hepatitis, galactosemia, and Alagille s syndrome. Furthermore, several resources are discussed for the diagnosis of cholestasis. CONCLUSIONS: The establishment of the diagnosis of cholestasis through the detection of hyperbilirubinemia in newborns who present jaundice after 14 days of life is a goal that could change the prognosis of several diseases responsible for neonatal cholestasis.

    Full Text Available In Western developed countries, Listeria monocytogenes is not an uncommon pathogen in neonates. However, neonatal listeriosis has rarely been reported in Taiwan. We describe two cases collected from a single medical institute between 1990 and 2005. Case 1 was a male premature baby weighing 1558 g with a gestational age of 31 weeks whose mother had fever with chills 3 days prior to delivery. Generalized maculopapular rash was found after delivery and subtle seizure developed. Both blood and cerebrospinal fluid culture collected on the 1st day yielded L. monocytogenes. In addition, he had ventriculitis complicated with hydrocephalus. Neurologic development was normal over 1 year of follow-up after ventriculoperitoneal shunt operation. Case 2 was a 28-weeks' gestation male premature baby weighing 1180 g. Endotracheal intubation and ventilator support were provided after delivery due to respiratory distress. Blood culture yielded L. monocyto-genes. Cerebrospinal fluid showed pleocytosis but the culture was negative. Brain ultrasonography showed ventriculitis. Sudden deterioration with cyanosis and bradycardia developed on the 8th day and he died on the same day. Neonatal listeriosis is uncommon in Taiwan, but has significant mortality and morbidity. Early diagnosis of perinatal infection relies on high index of suspicion in perinatal health care professionals. [J Formos Med Assoc 2007;106(2:161-164

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors...... are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012...... that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment. CONCLUSIONS In bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical...

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor

    Finland has made both multilateral and bilateral agreements on the exchange of information related to radiation safety. The first arrangements for international agreements and exchange of information were made after the Chernobyl accident. In 1987, Finland joined the convention on early notification of a nuclear power accident coordinated by International Atomic Energy Agency. The convention is applied to accidents that cause of may cause emissions of radioactive substances that might affect the radiation safety of another country. Besides the convention on early notification, some other individual agreements have also been made. These include the International Nuclear Event Scale (INES) system and power companies own information exchange systems. Finland has conducted bilateral agreements with the Nordic countries and the Soviet Union on the notification of accidents and exchange of nuclear power plant information. Today, Russia answers for the Soviet Union's contractual obligations. (orig.)

    Local anesthetics are the most widely consumed drugs in the practice of medicine which provide a loss of sensation in a certain body part without loss of consciousness or impairment of central control of essential functions. Lidocaine (I) is the most commonly local anaesthetic drug which is widely used in all species due to its fabulous diffusing and penetrating properties as well as prompt onset of surgical analgesia. In this study, new aminobenzothiazole (with many useful biological and pharmacological properties) analogues were synthesized by changing of amine moiety of I. Both acute and chronic pain properties of new compounds (II-VI) were studied by using the tail immersion and formalin tests on mice and the outcomes were compared with control and lidocaine groups. According to the results, aminobenzothiazole derivatives are better candidates than diethylamine group for replacement on amine moiety of I. Also, derivatives with electron-withdrawing groups on this amine (V and VI) could decrease pain better than electron-donating ones (II and III) (specially on position 6 of this amine, II and V) which may be of concern for blockade of specific sodium channels by these new compounds.

    Purpose: Radiation-induced xerostomia still represents a common side effect after radiotherapy for head-and-neck malignancies. The aim of the present study was to examine the radioprotective effect of lidocaine hydrochloride during fractionated radiation in an experimental animal model. Methods and Materials: To evaluate the influence of different radiation doses on salivary gland function and the radioprotective effect of lidocaine, rabbits were irradiated with 15, 25, 30, and 35 Gy (equivalent doses in 2-Gy fractions equivalent to 24, 40, 48, and 56 Gy, respectively). Lidocaine hydrochloride (10 and 12 mg/kg) was administered before every radiation fraction in the treatment groups. Salivary gland function was assessed by flow sialometry and sialoscintigraphy, and the morphologic changes were evaluated using transmission electron microscopy. Results: Functional impairment was first observed after 35 Gy and pretreatment with lidocaine improved radiation tolerance of both parotid and submandibular glands. The use of 12 mg/kg lidocaine was superior and displayed significant radioprotection with regard to flow sialometry and sialoscintigraphy. The ultrastructure was largely preserved after pretreatment with both lidocaine doses. Conclusions: Lidocaine represents an effective radioprotective agent and a promising approach for clinical application to avoid radiation-induced functional impairment of salivary glands.

    The purpose of this study was to investigate the tissue distribution of lidocaine hydrochloride in mandibular bone marrow after intraosseous anesthesia (IOA) in rabbits. We used macroautoradiography to examine the tissue distribution of a (14)C-labeled 2% lidocaine hydrochloride solution containing 1:80,000 epinephrine ((14)C-lidocaine). Under general anesthesia, (14)C-lidocaine was injected intraosseously or paraperiosteally. After IOA, animals were divided into three groups and observed at 1 (IOA-1), 5 (IOA-5), and 10 minutes (IOA-10) after injection. After infiltration anesthesia (IA), animals were observed at 1 minute after injection. The accumulation of (14)C-lidocaine was observed around the injection site in both the IA and the IOA groups. Paraperiosteally injected (14)C-lidocaine diffused to the surrounding tissues such as the lip, whereas IOA showed concentrated accumulation around the root apex throughout the experiment. The distribution area was significantly smaller in the IOA-1 group than in the IA group. The distribution area in the IOA-5 group was larger than those in the IOA-1 and IOA-10 groups. The accumulation of (14)C-lidocaine injected by IOA in rabbits was concentrated around the root apex. These results may explain the rapid onset time of IOA.

    IGOR NAGAI YAMAKI

    Full Text Available ABSTRACT Objective: to evaluate the effects of blocking the regulation of vascular tone on the ischemia and reperfusion syndrome in rats through the use of lidocaine in the postconditioning technique. Methods: we randomized 35 rats into seven groups of five animals: Group 1- Control; Group 2- Ischemia and Reperfusion; Group 3- Ischemia, Reperfusion and Saline; Group 4- Ischemic Postconditioning; Group 5- Ischemic Postconditioning and Saline; Group 6- Lidocaine; Group 7- Ischemic Postconditioning and Lidocaine. Except for the control group, all the others were submitted to renal ischemia for 30 minutes. In postconditioning groups, we performed ischemia and reperfusion cycles of five minutes each, applied right after the main ischemia. In saline and lidocaine groups, we instilled the substances at a rate of two drops per minute. To compare the groups, we measured serum levels of urea and creatinine and also held renal histopathology. Results: The postconditioning and postconditioning + lidocaine groups showed a decrease in urea and creatinine values. The lidocaine group showed only a reduction in creatinine values. In histopathology, only the groups submitted to ischemic postconditioning had decreased degree of tubular necrosis. Conclusion: Lidocaine did not block the effects of postconditioning on renal ischemia reperfusion syndrome, and conferred better glomerular protection when applied in conjunction with ischemic postconditioning.

    Full Text Available Roland Staud,1 Taylor Kizer,1 Michael E Robinson2 1Department of Medicine, College of Medicine, 2Department of Clinical and Health Psychology, University of Florida, Gainesville, FL, USA Objective: Patients with chronic fatigue syndrome (CFS complain of long-lasting fatigue and pain which are not relieved by rest and worsened by physical exertion. Previous research has implicated metaboreceptors of muscles to play an important role for chronic fatigue and pain. Therefore, we hypothesized that blocking impulse input from deep tissues with intramuscular lidocaine injections would improve not only the pain but also fatigue of CFS patients. Methods: In a double-blind, placebo-controlled study, 58 CFS patients received 20 mL of 1% lidocaine (200 mg or normal saline once into both trapezius and gluteal muscles. Study outcomes included clinical fatigue and pain, depression, and anxiety. In addition, mechanical and heat hyperalgesia were assessed and serum levels of lidocaine were obtained after the injections. Results: Fatigue ratings of CFS patients decreased significantly more after lidocaine compared to saline injections (p = 0.03. In contrast, muscle injections reduced pain, depression, and anxiety (p < 0.001, but these changes were not statistically different between lidocaine and saline (p > 0.05. Lidocaine injections increased mechanical pain thresholds of CFS patients (p = 0.04 but did not affect their heat hyperalgesia. Importantly, mood changes or lidocaine serum levels did not significantly predict fatigue reductions. Conclusion: These results demonstrate that lidocaine injections reduce clinical fatigue of CFS patients significantly more than placebo, suggesting an important role of peripheral tissues for chronic fatigue. Future investigations will be necessary to evaluate the clinical benefits of such interventions. Keywords: muscle injections, lidocaine, metaboreceptor, chronic fatigue

    Summary Bilateral adrenal hemorrhages rarely occur during the neonatal period and are often associated with traumatic vaginal deliveries. However, the adrenal gland has highly regenerative capabilities and adrenal insufficiency typically resolves over time. We evaluated a newborn female after experiencing fetal macrosomia and a traumatic vaginal delivery. She developed acidosis and acute renal injury. Large adrenal hemorrhages were noted bilaterally on ultrasound, and she was diagnosed with a...

    To investigate physiological and antinociceptive effects of electroacupuncture (EA) with lidocaine epidural nerve block in goats. Prospective experimental trial. Forty-eight hybrid male goats weighing 27 ± 2 kg. The goats were randomly assigned to six groups: L2.2, epidural lidocaine (2.2 mg kg -1 ); L4.4, epidural lidocaine (4.4 mg kg -1 ); EA; EA-L1.1, EA with epidural lidocaine (1.1 mg kg -1 ); EA-L2.2, EA with epidural lidocaine (2.2 mg kg -1 ); and EA-L4.4, EA with epidural lidocaine (4.4 mg kg -1 ). EA was administered for 120 minutes. Epidural lidocaine was administered 25 minutes after EA started. Nociceptive thresholds of flank and thigh regions, abdominal muscle tone, mean arterial pressure (MAP), heart rate (HR), respiratory frequency (f R ) and rectal temperature were recorded at 30, 60, 90, 120, 150 and 180 minutes. Lidocaine dose-dependently increased nociceptive thresholds. There were no differences in nociceptive thresholds between L4.4 and EA from 30 to 120 minutes. The threshold in EA-L2.2 was lower than in EA-L4.4 from 30 to 120 minutes, but higher than in EA-L1.1 from 30 to 150 minutes or in L4.4 from 30 to 180 minutes. The abdominal muscle tone in EA-L2.2 was higher at 30 minutes, but lower at 90 and 120 minutes than at 0 minutes. There were no differences in muscle tone between L4.4 and L2.2 or EA-L4.4, and between any two of the three EA-lidocaine groups from 0 to 180 minutes. The f R and HR decreased in L4.4 at 60 and 90 minutes compared with 0 minutes. No differences in f R , HR, MAP and temperature among the groups occurred from 30 to 180 minutes. EA combined with 2.2 mg kg -1 epidural lidocaine provides better antinociceptive effect than 4.4 mg kg -1 epidural lidocaine alone in goats. EA provided antinociception and allowed a decrease in epidural lidocaine dose. Copyright © 2017 Association of Veterinary Anaesthetists and American College of Veterinary Anesthesia and Analgesia.

    The objective of this study was to describe and compare the efficacy and duration of topical anaesthesia induced by 2 per cent lidocaine (L), 0.5 per cent bupivacaine (B) and 1 per cent ropivacaine (R) in the dog using 24 clinically healthy beagles with normal ocular examination. Dogs were randomly divided into three groups: 2 per cent lidocaine (n=8), 0.5 per cent bupivacaine (n=8) and 1 per cent ropivacaine (n=8). The baseline corneal touch threshold (CTT) was measured using a Cochet-Bonnet aesthesiometer. Following baseline CTT measurement, a single drop of the assigned anaesthetic was applied to each eye and the CTT was measured bilaterally within one minute after administration and every five minutes until the basal CTT value was restored. Data were analysed with non-parametric analysis of variance models and Dunnet's test for post hoc analysis. One per cent ropivacaine was the most effective drug (LCTTmax=3 cm, BCTTmax=2 cm, RCTTmax=0 cm; Pper cent ropivacaine had the maximal and quickest anaesthetic effect. This drug could be used for specific diagnostic procedures where quick and short, but effective, corneal anaesthesia is needed.

    2010-02-01

    Hypoglycemia in the newborn may be associated with both acute decompensation and long-term neuronal loss. Studies of the cause of hypoglycemic brain damage and the relationship of hypoglycemia to disorders associated with hyperinsulinism have aided in our understanding of this common clinical finding. A recent consensus workshop concluded that there has been little progress toward a precise numerical definition of neonatal hypoglycemia. Nonetheless, newer brain imaging modalities have provided insight into the relationship between neuronal energy deficiency and central nervous system damage. Laboratory studies have begun to reveal the mechanism of hypoglycemic damage. In addition, there is new information about hyperinsulinemic hypoglycemia of genetic, environmental, and iatrogenic origin. The quantitative definition of hypoglycemia in the newborn remains elusive because it is a surrogate marker for central nervous system energy deficiency. Nonetheless, the recognition that hyperinsulinemic hypoglycemia, which produces profound central nervous system energy deficiency, is most likely to lead to long-term central nervous system damage, has altered management of children with hypoglycemia. In addition, imaging studies on neonates and laboratory evaluation in animal models have provided insight into the mechanism of neuronal damage.

    Dioctophyma renale is a parasite that frequently occurs in animals but rarely in humans. The present report describes the clinical observations of a D. renale infection in a 51-yr-old woman. Its clinical signs and diagnostic findings were unspecific until giant worms were observed in the urine and histological findings confirmed it was a D. renale infection. She refused treatment and died of bilateral renal function failure. This is the first confirmed report to follow the natural progression of D. renale infection in a human. Here, we discuss a conservative therapeutic approach and features associated with this parasitic infection.

    This report describes a rare case of recurrent bilateral focal myositis and its successful treatment via methotrexate. A 38-year-old man presented myalgia of the right gastrocnemius in May 2005. Magnetic resonance imaging showed very high signal intensity in the right gastrocnemius on short-tau inversion recovery images. A muscle biopsy revealed inflammatory CD4+ cell-dominant myogenic change. Focal myositis was diagnosed. The first steroid treatment was effective. Tapering of prednisolone, however, repeatedly induced myositis relapse, which progressed to multiple muscle lesions of both lower limbs. Initiation of methotrexate finally allowed successful tapering of prednisolone, with no relapse in the past 4 years.

    Full Text Available The objective of the study was to compare the concentration of lidocaine in different body fluids/tissues after subarachnoid space and intravenous administrations of a lethal dose of lidocaine. Totally 18 dogs were used in the experiment. Six dogs were given subarachnoid anesthesia, another were given an intravenous injection of a dose of 75 mg/kg weight of lidocaine hydrochloride in 5 min and the last 6 dogs were used as the blank control dogs and given a subarachnoid space injection or a femoral artery injection of the same volume of sodium chloride. As soon as its vital signs disappeared, each dog was dissected and the specimen, such as brain, cerebrospinal fluid (CSF in lateral ventricle, CSF in subarachnoid space, spinal cord (cervical spinal cord, thoracic spinal cord, lumbar spinal cord, and waist spinal cord, heart, lung, liver, spleen, kidney, bile, urine, heart blood, peripheral blood, muscle in injection location, and muscle in no injection location, were collected for analysis of lidocaine immediately. Analysis was performed with gas chromatography-mass spectrometry (GC-MS. From the maximum to the minimum, the order of lidocaine concentration detected in the subarachnoid space-administered dogs was as follows: CSF in subarachnoid space, waist spinal cord, thoracic spinal cord, CSF in lateral ventricle, lumbar spinal cord, cervical spinal cord, lung, kidney, muscle in injection location, heart, brain, spleen, heart blood, liver, peripheral blood, bile, muscle in no injection location, and urine. The order of lidocaine concentration detected in the intravenously administered dogs was as followed: Kidney, heart, lung, spleen, brain, liver, peripheral blood, bile, heart blood, cervical spinal cord, thoracic spinal cord, muscle in injection location, lumbar spinal cord, muscle in no injection location, CSF in subarachnoid space, urine, and CSF in lateral ventricle.

    This article reviews 12 patients with bilateral acoustic neuromas. The sex incidence was equal and the mean age at diagnosis was 26.2 years. The family history was positive in nine of the patients. Five patients have had incomplete surgical removal of acoustic neuromas on both sides. Two of them are completely deaf and the other three have severe sensorineural hearing loss in one ear and no hearing in the other ear. In five patients the tumour on one side has been operated on and the other side is being observed with at least short-term preservation of good hearing. The remaining two patients died of intra-cranial complications, one of them post-operatively. Four patients developed facial palsy immediately following surgery and one developed facial weakness 6 months after surgery. Guidelines are discussed for the care of these patients including the timing of surgery and alternative treatment options (observation, radio-surgery and chemotherapy). This is essentially a group of young individuals who have had multiple operations for bilateral acoustic tumours and associated manifestations and for whom the disease and the sequelae of treatment can be tragic.

    Little is known about the metabolising capacity of the human skin in relation to topically applied drugs and formulations. We chose lidocaine as a model compound since the metabolic pathways are well known from studies concerning hepatic metabolism following systemic drug administration. However......, the enzymes involved are also expressed in the skin. Hence, the aim of the current study was to investigate the extent of the cutaneous in vivo metabolism of topically applied lidocaine in human volunteers. A dose of 5 mg/cm(2) of Xylocaine(R) (5% lidocaine) ointment was applied onto the buttock skin...... of the volunteers. After 2 h, residual formulation was removed, and two 4-mm punch biopsies were taken from each volunteer. The quantity of lidocaine extracted from the skin samples (epidermis + dermis) was 109 +/- 43 ng/mm(2) skin. One metabolite (monoethylglycine xylidide, MEGX) was detected in skin from 7...

    Full Text Available Topical and/or intracameral administration of anticholinergic and/or sympathomimetic mydriatic agents which are usually used for pupillary dilation during cataract surgery, have some disadvantages such as slow onset of dilation and adverse ocular and systemic effects. We evaluated intracameral injection of preservative-free 1% lidocaine without using any preoperative or intraoperative mydriatics to induce pupil dilation in 31 consecutive eyes scheduled for phacoemulsification cataract extraction and intraocular lens implantation. Pupil diameter was measured before and 90 sec after intracameral lidocaine injection. After intracameral lidocaine injection, the mean pupil diameter was significantly greater than the baseline measurement (P< 0.001. No additional mydriatics were needed up to the end of the operations. Intracameral preservative-free lidocaine 1% has a rapid and effective mydriasis that could be a safe alternative to topical and intracameral mydriatics in phacoemulsification.

    The use of injectable local anesthetic solutions to facilitate pain-free surgery is an integral component of many procedures performed by the plastic surgeon. In many instances, a solution that has both rapid onset and prolonged duration of analgesia is optimal. A combination of lidocaine and bupivacaine, plain or with epinephrine, is readily available in most Canadian health care settings where such procedures are performed, and fulfills these criteria. However, commercially available solutions of both medications are acidic and cause a burning sensation on injection. Buffering to neutral pH with sodium bicarbonate is a practical method to mitigate the burning sensation, and has the added benefit of increasing the fraction of nonionized lipid soluble drug available. The authors report on the proportions of the three drugs to yield a neutral pH, and the results of an initial survey regarding the use of the combined solution with epinephrine in hand surgery.

    2004-05-01

    To evaluate the role of a new formulation of lidocaine (ELA-max) in local anesthesia in children and compare it with the eutectic mixture of local anesthetics (EMLA). Relevant literature was identified by a MEDLINE search (1966-November 2003) using the search terms ELA-max and EMLA. Bibliographies of selected articles were also examined to include all relevant investigations. The product manufacturer was contacted for inclusion of the most recent data available. Topical anesthesia in children is clinically challenging. ELA-max has been shown to be as effective as EMLA for venipuncture in children, but with faster onset. Adverse effects, such as transient blanching with redness and erythema, have been reported. Further investigation is needed to determine the effectiveness of ELA-max on other painful procedures in children, as well as its safety.

    Full Text Available Abstract Background Systemic sclerosis (scleroderma; SSc is an orphan disease with the highest case-specific mortality of any connective-tissue disease. Excessive collagen deposit in affected tissues is a key for the disease's pathogenesis and comprises most of the clinical manifestations. Lidocaine seems to be an alternative treatment for scleroderma considering that: a the patient's having excessive collagen deposits in tissues affected by scleroderma; b the patient's demonstrating increased activity of the enzyme prolyl hydroxylase, an essential enzyme for the biosynthesis of collagen; and c lidocaine's reducing the activity of prolyl hydroxylase. The aim of this study was to evaluate the efficacy and safety of lidocaine in treating scleroderma. Methods A randomized double-blind clinical trial included 24 patients with scleroderma randomized to receive lidocaine or placebo intravenously in three cycles of ten days each, with a one-month interval between them. Outcomes: cutaneous (modified Rodnan skin score, oesophageal (manometry and microvascular improvement (nailfold capillaroscopy; improvement in subjective self-assessment and in quality of life (HAQ. Results There was no statistically significant difference between the groups for any outcome after the treatment and after 6-months follow-up. Improvement in modified Rodnan skin score occurred in 66.7% and 50% of placebo and lidocaine group, respectively (p = 0.408. Both groups showed an improvement in subjective self-assessment, with no difference between them. Conclusions Despite the findings of a previous cohort study favouring the use of lidocaine, this study demonstrated that lidocaine at this dosage and means of administration showed a lack of efficacy for treating scleroderma despite the absence of significant adverse effects. However, further similar clinical trials are needed to evaluate the efficacy of lidocaine when administered in different dosages and by other means.

NY, USA; 3Anesthesiology Department, Pain Management Unit, University Hospital of Bellvitge, L'Hospitalet de Llobregat, Spain Abstract: Topical 5% lidocaine medicated plasters represent a well-established first-line option for the treatment of peripheral localized neuropathic pain (LNP. This review provides an updated overview of the clinical evidence (randomized, controlled, and open-label clinical studies, real-life daily clinical practice, and case series. The 5% lidocaine medicated plaster effectively provides pain relief in postherpetic neuralgia, and data from a large open-label controlled study indicate that the 5% lidocaine medicated plaster is as effective as systemic pregabalin in postherpetic neuralgia and painful diabetic polyneuropathy but with an improved tolerability profile. Additionally, improved analgesia and fewer side effects were experienced by patients treated synchronously with the 5% lidocaine medicated plaster, further demonstrating the value of multimodal analgesia in LNP. The 5% lidocaine medicated plaster provides continued benefit after long-term (≤7 years use and is also effective in various other LNP conditions. Minor application-site reactions are the most common adverse events associated with the 5% lidocaine medicated plaster; there is minimal risk of systemic adverse events and drug–drug interactions. Although further well-controlled studies are warranted, the 5% lidocaine medicated plaster is efficacious and safe in LNP and may have particular clinical benefit in elderly and/or medically compromised patients because of the low incidence of adverse events.

    Full Text Available Background and Objectives: A novel lozenge formulation with advantages of ease of drug administration, palatable taste and improved patient compliance could be the preferred mode of topical pharyngeal anesthesia during upper gastrointestinal endoscopy (UGE. This randomized, open-label, active-controlled study was conducted to evaluate the efficacy and safety of lidocaine lozenges versus lidocaine spray in the diagnostic gastroduodenal endoscopy in Indian patients. Subjects and Methods: Two hundred and forty-seven patients of either sex (18-80 years undergoing diagnostic gastroduodenal endoscopy were randomized either to; lidocaine lozenge 200 mg or lidocaine spray 200 mg to be applied as a single dose before gastroduodenal endoscopy. Ease of procedure, level of gag reflex, ease of application of the local anesthetic, and investigators global assessment were the primary efficacy endpoints. Need for rescue medication and patient′s global assessment were secondary efficacy endpoints. The incidence of any adverse event was the safety endpoint. Between groups, comparison was done by using appropriate statistical test. Results: Investigator reported significantly lesser procedural difficulty (P = 0.0007 and suppressed gag reflex (P < 0.0001 during UGE with lidocaine lozenge compared to spray. Ease of application of local anesthetic was reported easy in significantly more patients as compared with lidocaine spray (P = 0.001. Global assessment by patient and physician was favorable toward lozenge. Incidences of adverse events were similar in both the groups. Conclusions: The study suggests that lidocaine lozenges are an easier way of applying local oropharyngeal anesthesia, produces better suppression of gag reflex and makes the procedure easier when compared with lidocaine spray.

    To determine whether the application of subconjunctival 2% lidocaine/0.1% methylparaben for anesthesia may reduce rates of endophthalmitis after intravitreal (IVT) injection. We performed in vitro experiments to determine the antibacterial properties of 2% lidocaine/0.1% methylparaben (lidocaine) against causative organisms of endophthalmitis. Isolates of Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus viridans from patients with endophthalmitis were incubated with or without lidocaine. Aliquots (100 µL) were plated on Mueller-Hinton (S. aureus and S. epidermidis) or blood agar plates (S. viridans) at 0, 10, 30, 120, and 240 minutes, and colonies were counted after 24 hours. A retrospective review of 15,042 IVT injections was performed from January 2004 to February 2011 to determine the rate of endophthalmitis with or without application of subconjunctival lidocaine for anesthesia. Lidocaine demonstrated rapid bactericidal effects against all 3 organisms. After 10 minutes of exposure, there was approximately a 90% (P < 0.01), 95% (P < 0.001), and 92% (P < 0.001) reduction in colony forming units when compared with time 0 for S. aureus, S. epidermidis, and S. viridans, respectively. Complete elimination of colony forming units occurred at subsequent time points for each organism in contrast to logarithmic increase for control plates. There were a total of 0 cases of endophthalmitis of 6,853 IVT injections performed with subconjunctival lidocaine and 8 cases of endophthalmitis of 8,189 (0.1%) IVT injections performed with other methods of anesthesia (P = 0.03). Application of subconjunctival 2% lidocaine/0.1% methylparaben for anesthesia may reduce the incidence of endophthalmitis after IVT injection.

    The pharmacokinetics and pharmacodynamics of lidocaine were studied in nine chronically prepared pregnant ewes and their fetuses at a mean ( +/- SE) gestation of 119 +/- 1.0 days, and the results were compared to the data previously published for ten animals at 138 +/- 1.2 days of gestation (term 148 days). Lidocaine was infused intravenously to the mother at a constant rate of 0.1 mg.kg-1.min-1 over a period of 180 min, in order to reach a steady-state maternal plasma lidocaine concentration of approximately 2 micrograms/ml. Maternal and fetal blood samples and maternal urine were collected at intervals throughout the infusion for determination of pH, blood gases, and lidocaine concentrations. Maternal and fetal heart rate, blood pressure, and intraamniotic pressure were continuously recorded. Fetal cardiac output and organ blood flow were determined before and at the end of lidocaine infusion using radionuclide-labeled microspheres. Lidocaine tissue concentrations were determined in several maternal and fetal organs excised at the end of infusion. In both groups, the steady-state plasma concentrations of lidocaine were similar; namely, 2.3 +/- 0.17 and 2.1 +/- 0.21 micrograms/ml in preterm and term ewes, respectively. There were also no significant differences in steady-state plasma drug concentrations in preterm and term fetuses (1.3 +/- 0.11 and 1.2 +/- 0.15 micrograms/ml). The mean fetal maternal concentration ratios (F/M) were the same; namely, 0.6. Maternal urinary excretion of lidocaine correlated with urine pH, being greater in the more acid urine. Tissue uptake of drug tended to be higher in the preterm than term mothers, but only significantly so in the brain and adrenals.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available BACKGROUND AND OBJECTIVE: Postoperative pain treatment in mastectomy remains a major challenge despite the multimodal approach. The aim of this study was to investigate the analgesic effect of intravenous lidocaine in patients undergoing mastectomy, as well as the postoperative consumption of opioids. METHODS: After approval by the Human Research Ethics Committee of the Instituto de Medicina Integral Prof. Fernando Figueira in Recife, Pernambuco, a randomized, blind, controlled trial was conducted with intravenous lidocaine at a dose of 3 mg/kg infused over 1 h in 45 women undergoing mastectomy under general anesthesia. One patient from placebo group was. RESULTS: Groups were similar in age, body mass index, type of surgery, and postoperative need for opioids. Two of 22 patients in lidocaine group and three of 22 patients in placebo group requested opioid (p = 0.50. Pain on awakening was identified in 4/22 of lidocaine group and 5/22 of placebo group (p = 0.50; in the post-anesthetic recovery room in 14/22 and 12/22 (p = 0.37 of lidocaine and placebo groups, respectively. Pain evaluation 24 h after surgery showed that 2/22 and 3/22 patients (p = 0.50 of lidocaine and placebo groups, respectively, complained of pain. CONCLUSION: Intravenous lidocaine at a dose of 3 mg/kg administered over a period of an hour during mastectomy did not promote additional analgesia compared to placebo in the first 24 h, and has not decreased opioid consumption. However, a beneficial effect of intravenous lidocaine in selected and/or other therapeutic regimens patients cannot be ruled out.

    Objective: To assess the feasibility and efficacy of transarterial lidocaine-lipiodol emulsion administration for controlling abdominal pain and preventing the arterial spasm resulting from TACE, and to evaluate the optimal amount of lidocaine administration. Methods: In a prospective trial of 120 consecutive patients with malignant tumor who underwent TACE were divided into three groups, those who received lidocaine-lipiodol emulsion administration (group A, n=40), those who received lidocaine bolus intraarterial infusion immediately before TACE (group B, n=40) and those who received no lidocaine injection before TACE, (group C, n=40). The degree of post-procedure pain was evaluated by a subjective method (using visual analogue scales from 0 to 10), and an objective method (amount of post-procedure analgesics). Incidence and degree of arterial spasm were assessed by DSA. Results: The correlative pain incidences between the three groups showed significant difference (P 0.05). Mean dose of intramuscular analgesics for controlling intolerable pain in group A and B was significantly lower than that of group C (P<0.05). There was no difference in the incidence of arterial spasm between group A and B but it was much lower in group C. Lipiodol deposit in malignant mass was densest in group A, especially in the metastatic nodules of the liver. Conclusions: Transarterial administration of lidocaine-lipiodol emulsion can not only reduce the incidence of pain during TACE, but also prevent the arterial spasm. It is much more effective than pre-TACE administration of pethidine and intraarterial infusion of lidocaine. The authors recommond routinely for the administration of lidocaine-lipiodol emulsion.

    The anaesthetic lidocaine is metabolised quickly to produce a series of metabolites, including several hydroxylated metabolites, which are further metabolised by addition of a glucuronic acid moiety. Analysis of these glucuronide metabolites in urine is performed indirectly by cleaving the glucuronic acid group using β-glucuronidase. However, direct analysis of intact glucuronide conjugates is a more straightforward approach as it negates the need for long hydrolysis incubations, and minimises the oxidation of sensitive hydrolysis products, while also distinguishing between the two forms of hydroxylated metabolites. A method was developed to identify three intact glucuronides of lidocaine in sheep urine using LC-MS/MS, which was further confirmed by the synthesis of glucuronide derivatives of 3OH-MEGX and 4OH-LIDO. Direct analysis of urine allowed the detection of the glucuronide metabolites of hydroxylidocaine (OH-LIDO), hydroxyl-monoethylglycinexylidide (OH-MEGX), and hydroxy-2,6-xylidine (OH-XYL). Analysis of urine before and after β-glucuronidase digestion showed that the efficiency of hydrolysis of these glucuronide metabolites may be underestimated in some studies. Analysis of urine in the current study from three different sheep with similar glucuronide metabolite concentrations resulted in different hydrolysis efficiencies, which may have been a result of different levels of substrate binding by matrix components, preventing enzyme cleavage. The use of direct analysis of intact glucuronides has the benefit of being less influenced by these matrix effects, while also allowing analysis of unstable metabolites like 4OH-XYL, which rapidly oxidises after hydrolysis. Additionally, direct analysis is less expensive and less time consuming, while providing more information about the status of hydroxylated metabolites in urine. Crown Copyright © 2018.

    Full Text Available Background: Different additives have been used with local anesthetics to provide prolonged duration of sensory block in spinal anesthesia. The aim of present study was to evaluate the onset and duration of sensory block of intrathecal dexamethasone and epinephrine as adjuvants to lidocaine in patients who were candidate for cesarean section. Materials and Methods: This double-blind clinical trial research was conducted on 90 pregnant women candidate for cesarean section under spinal anesthesia. Patients were randomly allocated to receive intrathecally either 75 mg hyperbaric lidocaine plus 100 μg epinephrine or 75 mg hyperbaric lidocaine plus 4 mg dexamethasone or 75 mg hyperbaric lidocaine. The onset and duration of sensory block as well as postoperative analgesia were assessed. Results: The time to reach the peak sensory block in lidocaine group was shorter than that of other two groups (p<0.001. Duration of sensory block in the control group, dexamethasone group, and epinephrine group were 64.16±7.99 min, 74.79±12.78 min, and 99.30±10.93 min, respectively (p<0.001. Conclusion: The present research shows that intrathecal dexamethasone and intrathecal epinephrine as adjuvant to lidocaine increases sensory block duration in the women candidate for cesarean section.

    Adrenaline is known to prolong the duration of local anesthesia but its effects on the pharmacokinetic processes of local anesthetic drugs are not fully understood. Our objective was to develop a compartmental model for quantification of adrenaline's impact on the pharmacokinetics of perineurally-injected lidocaine in the dog. Dogs were subjected to paravertebral brachial plexus block using lidocaine alone or adrenalinated lidocaine. Data was collected through a prospective, randomised, blinded crossover protocol performed over three periods. Blood samples were collected during 180 minutes following block execution. Compartmental pharmacokinetic models were developed and their goodness-of-fit were compared. The lowering effects of adrenaline on the absorption of lidocaine were statistically determined with one-sided tests. A one-compartment disposition model with two successive zero-order absorption processes best fitted our experimental data. Adrenaline decreased the peak plasma lidocaine concentration by approximately 60% (P Adrenaline decreased the absorption rate of lidocaine and prolonged the duration of its absorption.

    Full Text Available Breast tuberculosis is a rare form of tuberculosis. Moreover the disease is often overlooked and misdiagnosed as carcinoma or pyogenic abscess. Reports on breast tuberculosis from India have been few; reported incidence of breast tuberculosis amongst the total number of mammary conditions varies between 0.64 and 3.59 per cent. Bilateral involvement is still more uncommon (3%. Most accepted view for spread of infection is centripetal lymphatic spread as axillary node involvement was shown to occur in 50 to 75 per cent of cases of tubercular mastitis. Here we re-port a case of a young female who presented with draining sinuses in the breast and no axillary lymphadenopathy. Fine needle aspiration cytology (FNAC of breast lump showed evidence of granulomatous mastitis. She was given therapeutic trial of four drug antitubercular treatment. Both the lump disappeared and sinus healed after six months of antitubercular treatment. Thus a retrospective diagnosis of tu-bercular mastitis was made.

    Knowledge of the variations of the renal artery has grown in importance with increasing numbers of renal transplants, vascular reconstructions and various surgical and radio logic techniques being performed in recent years. We report the presence of bilateral triple renal arteries, discovered on routine dissection of a male cadaver. On the right side, one additional renal artery originated from the abdominal aorta (distributed to superior pole of the kidney) and one other originated from the right common iliac artery (distributed to lower pole of the kidney). On the left side, both additional renal arteries originated from the abdominal aorta. Our observation has been compared with variations described in the literature and their clinical importance has been emphasized. (author)

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    2010-05-01

    Full Text Available The aim of this study was to compare the effects of fentanyl or dexmedetomidine when used in combination with propofol and lidocaine for tracheal intubation without using muscle relaxants. Sixty patients with American Society of Anesthesiologists stage I risk were randomized to receive 1 mg/kg dexmedetomidine (Group D, n = 30 or 2 mg/kg fentanyl (Group F, n = 30, both in combination with 1.5 mg/kg lidocaine and 3 mg/kg propofol. The requirement for intubation was determined based on mask ventilation capability, jaw motility, position of the vocal cords and the patient's response to intubation and inflation of the endotracheal tube cuff. Systolic arterial pressure, mean arterial pressure, heart rate and peripheral oxygen saturation values were also recorded. Rate pressure products were calculated. Jaw relaxation, position of the vocal cords and patient's response to intubation and inflation of the endotracheal tube cuff were significantly better in Group D than in Group F (p < 0.05. The intubation conditions were significantly more satisfactory in Group D than in Group F (p = 0.01. Heart rate was significantly lower in Group D than in Group F after the administration of the study drugs and intubation (p < 0.05. Mean arterial pressure was significantly lower in Group F than in Group D after propofol injection and at 3 and 5 minutes after intubation (p < 0.05. After intubation, the rate pressure product values were significantly lower in Group D than in Group F (p < 0.05. We conclude that endotracheal intubation was better with the dexmedetomidine–lidocaine–propofol combination than with the fentanyl–lidocaine–propofol combination. However, side effects such as bradycardia should be considered when using dexmedetomidine.

    It has been suggested that at equivalent therapeutic concentrations, lidocaine and bupivacaine may have different cardiotoxic potency. In the isolated working rat heart preparation, the effect of a range of lidocaine and bupivacaine concentrations on glucose uptake and lactate production (LP) were observed. Insulin was added, 10 μ/L, to Ringer's solution containing 3 H-labeled glucose to measure the glycolytic flux (GF). The effect of the local anesthetics on LP at the indicated concentrations were similar. Lidocaine appears to depress the glycolytic flux from exogenous glucose to a lesser degree. Bupivacaine, 10 mg/L, depresses VO 2 to a greater degree than does lidocaine, 40 mg/L

    Full Text Available Aims. In spastic subjects, lidocaine is often used to induce a block predictive of the result provided by subsequent surgery. Lidocaine has been demonstrated to inhibit the Hoffmann (H reflex to a greater extent than the direct motor (M response induced by electrical stimulation, but the timecourse of these responses has not been investigated. Methods. An animal (rat model of the effects of lidocaine on M and H responses was therefore developed to assess this time course. M and H responses were recorded in 18 adult rats before and after application of lidocaine to the sciatic nerve. Results. Two to five minutes after lidocaine injection, M responses were markedly reduced (mean reduction of 44% and H reflexes were completely abolished. Changes were observed more rapidly for the H reflex. The effects of lidocaine then persisted for 100 minutes. The effect of lidocaine was therefore more prolonged on the H reflex than on the M response. Conclusion. This study confirms that lidocaine blocks not only alpha motoneurons but also Ia afferent fibres responsible for the H reflex. The authors describe, for the first time, the detailed time course of the effect of lidocaine on direct or reflex activation of motoneurons in the rat.

    To investigate the alleviation effect of vein pretreatment and granisetron/lidocaine combination on propofol injection-induced pain. Two hundreds patients scheduled for gynaecological laparoscopic operations were randomly divided into four groups: control group (group I), lidocaine group (group II), granisetron group (group III) and granisetron/lidocaine combination group (group IV), with 50 patients in each group. The patients in the above four groups received placebo (saline), lidocaine 20 mg, granisetron 2 mg and granisetron 2 mg plus lidocaine intravenously respectively. The patients were injected with one-forth of scheduled propofol via a dorsal hand vein after one minute of venous occlusion. The pain during the injection of propofol was evaluated. Pain occurred in 84% of patients in the control group, 46% in the lidocaine group, 52% in the granisetron group and 24% in the granisetron/lidocaine combination group. There was a significant reduction in pain incidence in the three experimental groups compared with the control group (Pgranisetron/lidocaine combination group than in the control group (Pgranisetron/lidocaine may be effective not only in attenuating pains during i.v. injection of propofol, but also in preventing postoperative nausea, vomiting and shivering.

    To assess the efficacy and safety of bupivacaine compared with lidocaine in local anesthesia of nasopharynx through meta-analysis. A number of medical literature data bases were searched electronically. Relevant journals and references of included studies were manually searched. Two reviewers independently performed data extraction and quality assessment. Four studies were included. Visual analog scale (VAS) scores, acceptable discomfort, and bleeding scores were analyzed for bupivacaine versus lidocaine. When considering the VAS scores, bupivacaine as a local anesthetic agent was better than lidocaine in controlling the pain of postoperative patients (p bupivacaine group demonstrated a higher acceptable discomfort than the patients in the lidocaine group (p = 0.008). With regard to the bleeding scores of the patients with nasal surgery, lidocaine was better at bleeding in postoperative patients compared with bupivacaine (p = 0.0007). These results indicated that bupivacaine showed better pain control of postoperative patients and acceptable discomfort in patients with upper gastrointestinal endoscopy. Lidocaine had a significantly increased ability the pain of patients with transnasal fiberoptic nasopharyngolaryngoscopic examination and bleeding in postoperative patients. No systemic adverse events were reported. Bupivacaine was found to have better promotion to pain control than did lidocaine for the patients after nasal surgery. Lidocaine had a significantly increased inhibition of bleeding in these postoperative patients; however, the efficacy between bupivacaine and lidocaine was unclear for the patients who had transnasal endoscopic examinations.

  2. Muscle-type nicotinic receptor blockade by diethylamine, the hydrophilic moiety of lidocaine

    2016-02-01

    Full Text Available Lidocaine bears in its structure both an aromatic ring and a terminal amine, which can be protonated at physiological pH, linked by an amide group. Since lidocaine causes multiple inhibitory actions on nicotinic acetylcholine receptors (nAChRs, this work was aimed to determine the inhibitory effects of diethylamine (DEA, a small molecule resembling the hydrophilic moiety of lidocaine, on Torpedo marmorata nAChRs microtransplanted to Xenopus oocytes. Similarly to lidocaine, DEA reversibly blocked acetylcholine-elicited currents (IACh in a dose-dependent manner (IC50 close to 70 μM, but unlike lidocaine, DEA did not affect IACh desensitization. IACh inhibition by DEA was more pronounced at negative potentials, suggesting an open-channel blockade of nAChRs, although roughly 30% inhibition persisted at positive potentials, indicating additional binding sites outside the pore. DEA block of nAChRs in the resting state (closed channel was confirmed by the enhanced IACh inhibition when pre-applying DEA before its co-application with ACh, as compared with solely DEA and ACh co-application. Virtual docking assays provide a plausible explanation to the experimental observations in terms of the involvement of different sets of drug binding sites. So, at the nAChR transmembrane (TM domain, DEA and lidocaine shared binding sites within the channel pore, giving support to their open-channel blockade; besides, lidocaine, but not DEA, interacted with residues at cavities among the M1, M2, M3 and M4 segments of each subunit and also at intersubunit crevices. At the extracellular (EC domain, DEA and lidocaine binding sites were broadly distributed, which aids to explain the closed channel blockade observed. Interestingly, some DEA clusters were located at the α-γ interphase of the EC domain, in a cavity near the orthosteric binding site pocket; by contrast, lidocaine contacted with all α-subunit loops conforming the ACh binding site, both in α-γ and

    Despite advances in the care of infants, there remain many newborns whose medical conditions are incompatible with sustained life. At times, healthcare providers and parents may agree that prolonging life is not an appropriate goal of care, and they may redirect treatment to alleviate suffering. While pediatric palliative treatment protocols are gaining greater acceptance, there remain some children whose suffering is unrelenting despite maximal efforts. Due to the realization that some infants suffer unbearably (ie, the burdens of suffering outweigh the benefits of life), the Dutch have developed a protocol for euthanizing these newborns. In this review, I examine the ethical aspects of 6 forms of end of life care, explain the ethical arguments in support of euthanasia, review the history and verbiage of the United States regulations governing limiting and withdrawing life-prolonging interventions in infants, describe the 3 categories of neonates for whom the Dutch provide euthanasia, review the published analyses of the Dutch protocol, and finally present some practical considerations should some form of euthanasia ever be deemed appropriate.

    Full Text Available Bilateral adrenal hemorrhages rarely occur during the neonatal period and are often associated with traumatic vaginal deliveries. However, the adrenal gland has highly regenerative capabilities and adrenal insufficiency typically resolves over time. We evaluated a newborn female after experiencing fetal macrosomia and a traumatic vaginal delivery. She developed acidosis and acute renal injury. Large adrenal hemorrhages were noted bilaterally on ultrasound, and she was diagnosed with adrenal insufficiency based on characteristic electrolyte changes and a low cortisol (4.2 μg/dL. On follow-up testing, this patient was unable to be weaned off of hydrocortisone or fludrocortisone despite resolution of hemorrhages on ultrasound. Providers should consider bilateral adrenal hemorrhage when evaluating critically ill neonates after a traumatic delivery. In extreme cases, this may be a persistent process.

    Full Text Available A case of bilateral persistent hyperplastic primary vitreous (PHPV in a 3-month-old male infant, who had bilateral leukokoria, is presented. The child was referred for imaging with a clinical suspicion of retinoblastoma. Gray-scale ultrasound evaluation revealed an echogenic band in the posterior segment of both globes, extending from the posterior surface of the lens capsule to the optic disc. Doppler examination revealed the presence of arterial flow in the band in both globes. Associated echogenic hemorrhage was also seen, which was confirmed by computed tomography. Most cases of PHPV are sporadic and unilateral, and bilateral PHPV is rare. The imaging features in this case suggest the diagnosis of bilateral PHPV and differentiate it from retinoblastoma. This entity, although infrequent, should be considered in the differential diagnosis while evaluating bilateral leukokoria.

    Full Text Available Dilek Sarici1, S Umit Sarici21Kecioren Research and Education Hospital, Kecioren, Ankara, 2Chief of Division of Neonatology, Division of Neonatology, Department of Pediatrics, Gulhane Military Medical Academy, Ankara, TurkeyAbstract: In this article, distribution of potassium (K+ in body fluids, pathophysiology, causes, clinical signs and symptoms, and the evaluation and treatment of neonatal hypokalemia are reviewed. K+ is the most important intracellular cation and normal serum K+ is stabilized between 3.5 and 5.5 mEq/L. Hypokalemia may be caused by increased renal losses, increased extrarenal (gastrointestinal losses, redistribution or prolonged insufficient K+ intake. Clinical signs and symptoms occur as the result of functional changes in striated muscle, smooth muscle, and the heart. Hypokalemia is usually asymptomatic when K+ levels are between 3.0 and 3.5 mEq/L; however, there may sometimes be slight muscle weakness. Moderate hypokalemia is observed when serum K+ is between 2.5 and 3.0 mEq/L. Proximal muscle weakness is observed most commonly in lower extremities; cranial muscles are normal, but constipation and distention are prominent. Severe hypokalemia develops when serum K+ falls below 2.5 mEq/L. Rhabdomyolysis, myoglobinuria, severe muscle weakness, paralysis, respiratory distress, and respiratory arrest are observed. The clinical signs and symptoms may be unremarkable in cases of chronically developing hypokalemia; however, appropriate treatment is essential when serum K+ level falls below 2.5 mEq/L as the most dangerous complication of hypokalemia is fatal cardiac arrythmia, and changes visible with electrocardiography may not always correlate with the level of hypokalemia. Sodium (Na+, K+, chloride (Cl-, bicarbonate, creatinine, blood sugar, magnesium (Mg, plasma renin activity, aldosterone, and blood gases should be investigated by laboratory testing.

    1987-01-01

    The clinical examination of the CNS in the neonate is often difficult in cases of complex pathology. Diagnostic imaging of the neonatal brain has become extremely useful and in the last decade has developed in two main directions: CT and US. MR imaging has been used recently with varying success in the diagnosis of pathology in the neonatal brain. Despite technical difficulties, this imaging method is likely to become increasingly important in the neonate. The paper examines the normal neonatal brain anatomy as seen with the different modalities, followed by pathologic conditions. Attention is directed to the common pathology, in asphyxiated newborns, the patholphysiology of intraventicular hemorrhage and periventricular leukomalacia in the preterm neonate, and hypoxic-ischemic brain injury in the term neonate. Pitfalls, artifacts, and problems in image interpretation are illustrated. Finally, the subsequent appearance of neonatal pathology later in infancy and childhood is discussed

    Peripheral intravenous catheter (PIV) insertion is a common, painful experience for many children in the pediatric emergency department. Although local anesthetics such as injected buffered lidocaine have been shown to be effective at reducing pain and anxiety associated with PIV insertion, they are not routinely used. ELA-Max, a topical local anesthetic, has the advantage of needle-free administration but has not been compared with buffered lidocaine for PIV insertion. To compare the reduction of pain and anxiety during PIV insertion provided by subcutaneous buffered 1% lidocaine or topical ELA-Max in children. A randomized trial in children 4 to 17 years old undergoing PIV insertion with 22-gauge catheters was conducted. Children received either buffered lidocaine or ELA-Max. Buffered lidocaine was administered by using 30-gauge needles to inject 0.1 to 0.2 mL subcutaneously just before PIV insertion. ELA-Max was applied to the skin and occluded with Tegaderm 30 minutes before PIV insertion. Self-reported Visual Analog Scale (VAS) questionnaires (rating on a scale of 1-10; 1 = no pain, anxiety) were completed by patients and their parents before PIV insertion to assess baseline perceptions about pain and anxiety associated with PIV insertion and immediately after PIV insertion to assess pain and anxiety associated with the experience. After PIV insertion, the nurse who inserted the PIV also completed a VAS questionnaire assessing technical difficulty and satisfaction with the local anesthesia. A blinded observer also completed a VAS questionnaire to assess pain and anxiety associated with the PIV insertion. Data were analyzed by using chi2 and t tests. Sixty-nine subjects were enrolled, and questionnaires were competed by all (mean age: 12.1 +/- 4.5 years; 61% female). There were no differences for buffered lidocaine and ELA-Max groups in age, gender, race, prior IV experience, or baseline pain and anxiety. There were no significant differences between buffered

    Wilms tumor is the most common renal tumor in children Synchronous bilateral Wilms tumor (BWT) accounts for 5% of all patients registered to the National Wilms Tumor Study Group (NWSTG). A 28-year-old female patient was presented to Oncology Institute with right kidney tumor. Her left kidney was resected due to Wilms tumor in the sixth month of her life. Abdominal ultrasound was performed and demonstrated a massive right kidney tumor. Then the abdominal CT was undertaken with the use of 16-slice CT scanner, revealing rotation displacement of the right kidney, with signs of compensative overgrowth and displaced upwards. In the lower and peripheral part of the kidney a nodular mass 7 X 10 X 9 cm in size was visible. The tumor was well-demarcated, showing heterogeneous contrast enhancement, extending from the inferio-lateral renal pole.The tumor was adjacent to iliopsoas muscle and abdominal cavity walls; no infiltration of those structures was noted. Described lesion surrounded inferio-medial part of the kidney, approaching kidney pelvis without infiltrating them. Supero-anterior and medial part of the kidney showed normal structure with correct contrasted urine excretion. Lymph nodes enlargement within periaortal area was not detected. Surgical procedure was performed resulting in excision of the tumor with kidney preservation. Histopathology examination revealed nephroblastoma. The tumor was surrounded by a thin, fibrous capsule. Surrounding parenchyma and far tissue were not involved. The CT examination performed 4 months after nephron sparing surgery revealed: right kidney of 137 X 51 mm in size, normally located, with correct structure and function. Multislice abdominal CT have clearly visualized the tumor of the single kidney, showing precise localization of the mass with relation to the kidney pelvis and vessels, allowing for nephron sparing surgical excision.

    A 39-year-old para 3 woman presented for elective caesarean section (lower segment caesarean section (LSCS)) for breech presentation. The patient had a strong history of atopy and anaphylaxis to paracetamol, codeine, penicillin and latex. The patient was asthmatic, triggered by aspirin. Epidural anaesthesia was unsuccessful and LSCS was carried out under spinal anaesthesia. Postoperatively the patient was unwilling to take analgesic medication due to fear of an allergic reaction. Three 5% lidocaine patches were applied to the wound for postoperative analgesia. This reduced the patient\\'s visual analogue scale pain score from 10\\/10 to 5\\/10 at rest and 10\\/10 to 7\\/10 with movement. Transcutaneous electrical nerve stimulation was added and this improved associated back pain, reducing the pain further to 2\\/10. This is the first description of lignocaine patch 5% for postoperative LSCS pain. It is suggested that this method of delivery of local anaesthetic, which is easy to apply and has minimal side effects, should be considered not as a sole agent but as part of a multimodal technique to address postoperative LSCS pain.

    A sensitive and accurate method was developed for the analysis of sulfanilamide, phenazone, and lidocaine hydrochloride content in pure form and pharmaceutical preparations using HPLC technique. Analysis was performed on column had the following specifications: SHIM-PACK CLC(M) C18(100A 0 , 5μm, 4.6 x 250 mm). And mobile phase consisting of tow phases: the first was methanol, the second consisting of pure form of [water, icy acetic acid, triethylamine in rate (240: 7: 3 v/v/v) respectively], and the two phases were mixed in rate (20:80) respectively, flow rate was 1.5 ml/min, at temperature 300 C, and detector in the ultraviolet range at wavelength 254 nm, consequently. We could separate and determinate the studied compounds in its mixtures, and reached to excellent linearity for each one with correlation coefficients equivalent to (0.9999). This supposed method was applied on prepared samples and pharmaceutical preparation contains of the three studied compounds. The relative standard deviations RSD (n=5) was smaller than (1.99%) for prepared samples and (2.11%) for the pharmaceutical preparation. So this method proved to be sensitive, accurate, is useful for quantitative control of pharmaceutical products. (author)

    Pharmacotherapy in patients with neuropathic pain syndromes (NPS) can be associated with long periods of trial and error before reaching satisfactory analgesia. The aim of this study was to investigate whether a short intravenous (i.v.) infusion of lidocaine may have a predictive value for the efficacy of oxcarbazepine. In total, 16 consecutive patients with NPS were studied in a prospective, uncontrolled, open-label study design. Each patient received i.v. lidocaine (5 mg/kg) within 30 min followed by a long-term oral oxcarbazepine treatment (900-1,500 mg/day). During an observation period of 28 days, treatment response was documented by a questionnaire including the average daily pain score documented on a numeric rating scale (NRS). A total of 6 out of 16 patients (38%) were lidocaine responders (defined as pain reduction >50% during the infusion), and 4 of 16 (25%) were oxcarbazepine responders. In total, 6 out of 16 participants (38%) discontinued oxcarbazepine treatment due to side effects. In an interim analysis predictive value of the lidocaine infusion was low with a Kendall's tau correlation coefficient of 0.29 and coefficient of determination R(2) of 0.119 (95% confidence interval -0.29 to 0.72). As a consequence of this low correlation, the study was discontinued for ethical reasons. In conclusion, lidocaine infusion has a low predictive value for effectiveness of oxcarbazepine-if at all.

    To evaluate three volumes of lidocaine for spermatic cord block to perform castration in cattle. Randomized blinded clinical study. Thirty mixed-breed Nellore cattle, aged 28-40 months and weighing 395±21 (352-452) kg [mean±standard deviation (range)]. Cattle were restrained in a chute and allowed to stand without sedation. Three milliliters of 2% lidocaine without epinephrine were infiltrated subcutaneously at each site of scrotal incision in all animals. The animals were allocated to three groups of 10 animals each. Lidocaine 2% was injected into each spermatic cord using a volume of 2, 3 or 4 mL in groups A, B, or C, respectively. The total volumes of lidocaine used were 10, 12, and 14 mL in groups A, B, and C, respectively. The duration of surgery and the retraction of the testicle (scored as positive or negative according to retraction of the testicle) during the procedure were recorded. The data were statistically analyzed by one-way anova followed by Tukey's and chi-square tests. Differences were considered significant when pcastration and following incisional infiltration of lidocaine, in adult cattle weighing about 400 kg.

    Objective: To report the MRI findings of brain damage observed in neonatal patients who suffered from isolated hypoglycemia and to explore the value of diffusion-weighted imaging(DWI) in early detection of neonatal hypoglycemic brain injury. Methods: Twelve neonates with isolated hypoglycemia (10 of the 12 were diagnosed to suffer from hypoglycemic encephalopathy) were enrolled in this study. They were first scanned at age from 3 days to 10 days with T 1 WI, T 2 WI and DWI(b is 0 s/mm 2 , 1000 s/mm 2 ), and 4 of them were then scanned from 7 days to 10 days following the initial scan. All acquired MR images were retrospectively analysed. Results: First series of DWI images showed distinct hyperintense signal in 11 cases in several areas including bilateral occipital cortex (2 cases), right occipital cortex (1 case), left occipital cortex and subcortical white matter(1 case), bilateral occipital cortex and subcortical white matter (2 cases), bilateral parieto-occipital cortex (2 cases), bilateral parieto-occipital cortex and subcortical white matter(2 cases), the splenium of corpus callosum (4 cases), bilateral corona radiata( 2 cases), left caudate nucleus and globus pallidus (1 case), bilateral thalamus (1 case), bilaterally posterior limb of internal capsule (1 case). In the initial T 1 WI and T 2 WI images, there were subtle hypointensity in the damaged cortical areas (3 cases), hyperintensity in the bilaterally affected occipital cortex( 1 case) on T 1 weighted images, and hyperintensity in the affected cortex and subcortical white matter with poor differentiation on T 2 weighted images. The followed-up MRI of 4 cases showed regional encephalomalacia in the affected occipital lobes(4 cases), slightly hyperintensity on T 2 weighted images in the damaged occipital cortex (2 cases), extensive demyelination (1 case), disappearance of hyperintensity of the splenium of corpus callosum (1 case), and persistent hyperintensity in the splenium of corpus callosum (1 case

    Objective: To study the effects of hormone, anesthetic and contrast medium on the activities of collagenase lysis. Methods: Nuclear tissues were divided into equal amount for different groups and same units of collagenase were used for the lysis. The only difference in the control group from experimental groups was that there were no dexamethasone, lidocaine or omnipaque but existing in experimental groups. Twenty four hours later, the concentrations of the hydroxyproline were determined in different groups and the data were analyzed by statistical software with computer. Results: 1. The concentrations of hydroxyproline in the dexamethasone group, lidocaine group and omnipaque group were significantly lower than that of control group, especially that of lidocaine group, P value was <0.05 or 0.01. 2. The concentrations of hydroxyproline in the dexamethasone + lidocaine group, dexamethasone + omnipaque group, lidocaine+omnipaque group and dexamethasone + lidocaine + omnipaque group were significantly lower than that of control group; and simultaneously lower in dexamethasone group, lidocaine group, omnipaque group respectively; P value was also <0.05 or 0.01. Conclusion: Dexamethasone, lidocaine and omnipaque can individually inhibit the activity of collagenase at different degrees, so they shouldn't be used together with collagenase in treating the lumber disc herniation.

    Although hypoglycemia may be common among neonates, brain injuries resulting from isolated neonatal hypoglycemia are rare. The condition may cause neurological symptoms such as stupor, jitteriness, and seizures, though in their absence, diagnosis delayed or difficult. Hypoglycemia was diagnosed in a three-day-old neonate after he visited the emergency department with loose stool, poor oral intake, and decreased activity, first experienced two days earlier. Two days after his visity, several episodes of seizure occurred. T2 and diffusion-weighted magnetic resonance (MR) scanning, performed at 11 days of age, revealed bilateral and symmetrical high signal intensity lesions in occipital, parietal, and temporal lobes. We report the MR findings of hypoglycemic encephalopathy in a neonate

    Full Text Available Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

    The lidocaine-salol binary system has been investigated by differential scanning calorimetry, direct visual observations, and X-ray powder diffraction, resulting in a temperature-composition phase diagram with a eutectic equilibrium. The eutectic mixture, found at 0.423 {+-} 0.007 lidocaine mole-fraction, melts at 18.2 {+-} 0.5 {sup o}C with an enthalpy of 17.3 {+-} 0.5 kJ mol{sup -1}. This indicates that the liquid phase around the eutectic composition is stable at room temperature. Moreover, the undercooled liquid mixture does not easily crystallize. The present binary mixture exhibits eutectic behavior similar to the prilocaine-lidocaine mixture in the widely used EMLA topical anesthetic preparation.

    The lidocaine patch 5% was developed to treat postherpetic neuralgia. Anecdotal experience at our institution suggests the lidocaine patch 5% decreases narcotic usage in patients with traumatic rib fractures. This trial was developed to define the patch's efficacy. Patients with rib fractures admitted to the trauma service at our Level I trauma center were enrolled and randomized in a 1 to 1 double-blind manner to receive a lidocaine patch 5% or placebo patch. Fifty-eight patients who met the inclusion criteria were enrolled from January 2007 to August 2008. Demographic and clinical information were recorded. The primary outcomes variable was total narcotic use, analyzed using the 1-tailed Mann-Whitney test. The secondary outcomes variables included non-narcotic pain medication, average pain score, pulmonary complications, and length of stay. Significance was defined based on a 1-sided test for the primary outcome and 2-sided tests for other comparisons, at p rib fractures, gender, trauma mechanism, preinjury lung disease, smoking history, percent of current smokers, and need for placement of chest tube between the lidocaine patch 5% and placebo groups. There was no difference between the lidocaine patch 5% and placebo groups, respectively, with regard to total IV narcotic usage: median, 0.23 units versus 0.26 units; total oral narcotics: median, 4 units versus 7 units; pain score: 5.6 +/- 0.4 versus 6.0 +/- 0.3 (mean +/- SEM); length of stay: 7.8 +/- 1.1 versus 6.2 +/- 0.7; or percentage of patients with pulmonary complications: 72.7% versus 72.0%. The lidocaine patch 5% does not significantly improve pain control in polytrauma patients with traumatic rib fractures.

    BACKGROUND AND OBJECTIVE: Respiratory burst is an essential component of the neutrophil\\'s biocidal function. In vitro, sodium thiopental, isoflurane and lidocaine each inhibit neutrophil respiratory burst. The objectives of this study were (a) to determine the effect of a standard clinical induction\\/tracheal intubation sequence on neutrophil respiratory burst and (b) to determine the effect of intravenous lidocaine administration during induction of anaesthesia on neutrophil respiratory burst. METHODS: Twenty ASA I and II patients, aged 18-60 years, undergoing elective surgery were studied. After induction of anaesthesia [fentanyl (2 microg kg-1), thiopental (4-6 mg kg-1), isoflurane (end-tidal concentration 0.5-1.5%) in nitrous oxide (66%) and oxygen], patients randomly received either lidocaine 1.5 mg kg-1 (group L) or 0.9% saline (group S) prior to tracheal intubation. Neutrophil respiratory burst was measured immediately prior to induction of anaesthesia, immediately before and 1 and 5 min after lidocaine\\/saline. RESULTS: Neutrophil respiratory burst decreased significantly after induction of anaesthesia in both groups [87.4 +\\/- 8.2% (group L) and 88.5 +\\/- 13.4% (group S) of preinduction level (P < 0.01 both groups)]. After intravenous lidocaine (but not saline) administration, neutrophil respiratory burst returned towards preinduction levels, both before (97.1 +\\/- 23.6%) and after (94.4 +\\/- 16.6%) tracheal intubation. CONCLUSION: Induction of anaesthesia and tracheal intubation using thiopentone and isoflurane, inhibit neutrophil respiratory burst. This effect may be diminished by the administration of lidocaine.

    Full Text Available ABSTRACTBACKGROUND AND OBJECTIVES: Injection pain after propofol administration is common and maydisturb patients' comfort. The aim of this study was to compare effectiveness of intravenous(iv nitroglycerin, lidocaine and metoprolol applied through the veins on the dorsum of hand orantecubital vein on eliminating propofol injection pain.METHOD: There were 147 patients and they were grouped according to the analgesic adminis-tered. Metoprolol (n = 31, Group M, lidocaine (n = 32, Group L and nitroglycerin (n = 29, GroupN were applied through iv catheter at dorsum hand vein or antecubital vein. Pain was evalu-ated by 4 point scale (0 - no pain, 1 --- light pain, 2 --- mild pain, 3 --- severe pain in 5, 10, 15and 20th seconds. ASA, BMI, patient demographics, education level and the effect of pathwaysfor injection and location of operations were analyzed for their effect on total pain score.RESULTS: There were no differences between the groups in terms of total pain score (p = 0.981.There were no differences in terms of total pain score depending on ASA, education level,location of operation. However, lidocaine was more effective when compared with metoprolol(p = 0.015 and nitroglycerin (p = 0.001 among groups. Although neither lidocaine nor metopro-lol had any difference on pain management when applied from antecubital or dorsal hand vein(p > 0.05, nitroglycerin injection from antecubital vein had demonstrated statistically lowerpain scores (p = 0.001.CONCLUSION: We found lidocaine to be the most effective analgesic in decreasing propofolrelated pain. We therefore suggest iv lidocaine for alleviating propofol related pain at operations.

    Full Text Available Objectives: Local anaesthesia is the standard of care during dental extractions. With the advent of newer local anesthetic agents, it is often difficult for the clinician to decide which agent would be most efficacious in a given clinical scenario. This study assessed the efficacy of equal-milligram doses of lidocaine and articaine in achieving surgical anaesthesia of maxillary posterior teeth diagnosed with irreversible pulpitis. Material and Methods: This case-series evaluated a total of 41 patients diagnosed with irreversible pulpitis in a maxillary posterior tooth. Patients randomly received an infiltration of either 3.6 mL (72 mg 2% lidocaine with 1:100,000 epinephrine or 1.8 mL (72 mg 4% articaine with 1:100,000 epinephrine in the buccal fold and palatal soft tissue adjacent to the tooth. After 10 minutes, initial anaesthesia of the tooth was assessed by introducing a sterile 27-gauge needle into the gingival tissue adjacent to the tooth, followed by relief of the gingival cuff. Successful treatment was considered to have occurred when the tooth was extracted with no reported pain. Data was analyzed with the Fisher’s exact test, unpaired t-test and normality test. Results: Twenty-one patients received lidocaine and 20 received articaine. Forty of the 41 patients achieved initial anaesthesia 10 minutes after injection: 21 after lidocaine and 19 after articaine (P = 0.488. Pain-free extraction was accomplished in 33 patients: 19 after lidocaine and 14 after articaine buccal and palatal infiltrations (P = 0.226. Conclusions: There was no significant difference in efficacy between equivalent doses of lidocaine and articaine in the anaesthesia of maxillary posterior teeth with irreversible pulpitis.

    In this large, sham-controlled, randomized trial, we examined the efficacy of the combination of standard treatment and paraspinous lidocaine injection compared with standard therapy alone in subjects with chronic low back pain. There is little research-based evidence for the routine clinical use of paraspinous lidocaine injection for low back pain. A total of 378 subjects with nonspecific chronic low back pain were randomized to 3 groups: paraspinous lidocaine injection, analgesics, and exercises (group 1, LID-INJ); sham paraspinous lidocaine injection, analgesics, and exercises (group 2, SH-INJ); and analgesics and exercises (group 3, STD-TTR). A blinded rater assessed the study outcomes at 3 time points: baseline, after treatment, and after 3 months of follow-up. There were increased frequency of pain responses and better low back functional scores in the LID-INJ group compared with the SH-INJ and STD-TTR groups. These effects remained at the 3-month follow-up but differed between all 3 groups. There were significant changes in pain threshold immediately after treatment, supporting the effects of this intervention in reducing central sensitization. Paraspinous lidocaine injection therapy is not associated with a higher risk of adverse effects compared with conventional treatment and sham injection. Its effects on hyperalgesia might correlate with changes in central sensitization. NCT02387567. There are few data to support paraspinous lidocaine injection use in patients with nonspecific chronic low back pain. Our results show that this therapy when combined with standard therapy significantly increases the number of responders versus standard treatment alone. Its effects on hyperalgesia might correlate with a change in central sensitization. Copyright © 2016. Published by Elsevier Inc.

    Over the last few years, numerous reviews and studies have awarded articaine hydrochloride local anaesthetic (LA) a superior reputation, with outcomes of different studies demonstrating a general tendency for articaine hydrochloride to outperform lidocaine hydrochloride for dental treatment. Nevertheless, there seems to be no clear agreement on which LA solution is more efficacious in dental treatment for children. There is no previous publication systematically reviewing and summarising the current best evidence with respect to the success rates of LA solutions in children. To evaluate the available evidence on the efficacy of lidocaine and articaine, used in paediatric dentistry. A systematic search was conducted on Cochrane CENTRAL Register of Controlled Trials, MEDLINE (OVID; 1950 to June 2017), Cumulative Index to Nursing and Allied Health Literature (CINAHL; EBSCOhost; 1982 to June 2017), EMBASE (OVID; 1980 to June 2017), SCI-EXPANDED (ISI Web of Knowledge; 1900 to June 2017), key journals, and previous review bibliographies through June 2017. Original research studies that compared articaine with lidocaine for dental treatment in children were included. Methodological quality assessment and assessment of risk of bias were carried out for each of the included studies. Electronic searching identified 525 publications. Following the primary and secondary assessment process, six randomised controlled trials (RCT) were included in the final analysis. There was no difference between patient self-reported pain between articaine and lidocaine during treatment procedures (SMD = 0.06, P-value = 0.614), and no difference in the occurrence of adverse events between articaine and lidocaine injections following treatment in paediatric patients (RR = 1.10, P-value = 0.863). Yet, patients reported significantly less pain post-procedure following articaine injections (SMD = 0.37, P-value = 0.013). Substantial heterogeneity was noted in the reporting of outcomes among studies

    The mechanisms of lip wound healing after bilateral crossing of the inferior alveolar nerve (IAN) were studied on Chinchilla rabbits in 3 experimental series, 6 animals per series. In group 1 bilateral crossing of IAN was carried out, in group 2 bilateral crossing of IAN was paralleled by removal of a mucous flap in the middle of the lower lip, and in group 3 the same wound as in group 2 was created, after which the wounds in this group were daily treated with a special ointment and a single injection of lidocaine (1% solution) under the wound. The nerve crossing led to development of ulcer on the lip with degenerative changes in the vascular walls, destruction of nerve fibers, and fragmentation of some axial cylinders. Crossing of IAN simultaneously with removal of the lower lip flap led to more severe degenerative changes in the tissue. Daily treatment of the lip with the ointment and lidocaine blocking normalized wound healing. A possible mechanism of the changes observed is discussed.

    2012-01-01

    Inverted papilloma (IP) is a benign tumor of the nasal cavity and paranasal sinuses that is unilateral in most cases. Bilateral IP, involving both sides of the nasal cavity and sinuses, is extremely rare. This paper describes a large IP that filled in both sides of the nasal cavity and sinuses, mimicking association with malignancy. The tumor was successfully treated by bilateral endoscopic medial maxillectomy (EMM). The patient is without evidence of the disease 24 months after surgery. If preoperative diagnosis does not confirm the association with malignancy in IP, endoscopic sinus surgery (ESS) should be selected, and ESS, including EMM, is a good first choice of the treatment for IP.

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    A randomized, single-blind trial of two spinal anesthetic solutions for outpatient laparoscopy was conducted to compare intraoperative conditions and postoperative recovery. Thirty women (ASA physical status I and II) were assigned to one of two groups. Group I patients received a small-dose hypobaric solution of 1% lidocaine 25 mg made up to 3 mL by the addition of fentanyl 25 micrograms. Group II patients received a conventional-dose hyperbaric solution of 5% lidocaine 75 mg (in 7.5% dextrose) made up to 3 mL by the addition of 1.5 mL 10% dextrose. All patients received 500 mL of crystalloid preloading. Spinal anesthesia was performed at L2-3 or L3-4 with a 27-gauge Quincke point needle. Surgery commenced when the level of sensory anesthesia reached T-6. Intraoperative hypotension requiring treatment with ephedrine occurred in 54% of Group II patients but not in any Group I patients. Median (range) time for full motor recovery was 50 (0-95) min in Group I patients compared to 90 (50-120) min in Group II patients (P = 0.0005). Sensory recovery also occurred faster in Group I patients (100 +/- 22 min) compared with Group II patients (140 +/- 27 min, P = 0.0001). Postoperative headache occurred in 38% of all patients and 70% of these were postural in nature. Oral analgesia was the only treatment required. Spinal anesthesia did not result in a significant incidence of postoperative backache. On follow-up, 96% said they found spinal needle insertion acceptable, 93% found surgery comfortable, and 90% said they would request spinal anesthesia for laparoscopy in future. Overall, this study found spinal anesthesia for outpatient laparoscopy to have high patient acceptance and a comparable complication rate to other studies. The small-dose hypobaric lidocaine-fentanyl technique has advantages over conventional-dose hyperbaric lidocaine of no hypotension and faster recovery.

    Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consisted in primary end-to-end tendon repair protected temporarily with cerclage wiring, followed by a short immobilization period and intensive rehabilitation program. Five months after surgery, the patient was able to fully participate in sport activities.

    2013-04-01

    The objectives of the present study were to quantitatively evaluate chemical permeability through human enamel/dentine using conductometry and to clarify if alternating current (AC) iontophoresis facilitates such permeability. Electrical impedance of different concentrations of lidocaine hydrochloride was measured using a bipolar platinum impedance probe. A quadratic curve closely fitted to the response functions between conductance and lidocaine hydrochloride. For analysis of the passage of lidocaine hydrochloride through human enamel/dentine, eight premolars that were extracted for orthodontic treatment were sectioned at the cemento-enamel junction. The tooth crowns were held between two chambers with a double O-ring. The enamel-side chamber was filled with lidocaine hydrochloride, and the pulp-side chamber was filled with extrapure water. Two platinum plate electrodes were set at the end of each chamber to pass alternating current. A simulated interstitial pulp pressure was applied to the pulp-side chamber. The change in the concentration of lidocaine hydrochloride in the pulp-side chamber was measured every 2min using a platinum recording probe positioned at the centre of the pulp-side chamber. Passive entry without iontophoresis was used as a control. The level of lidocaine hydrochloride that passed through enamel/dentine against the dentinal fluid flow increased with time. Electrical conductance (G, mho) correlated closely to the concentration (x, mmol/L) of lidocaine hydrochloride (G=2.16x(2)+0.0289x+0.000376, r(2)=0.999). Lidocaine hydrochloride can pass through enamel/dentine. Conductometry showed that the level of lidocaine hydrochloride that passed through enamel/dentine was increased by AC iontophoresis.

This was an equally randomized, double-blind, placebo-controlled, parallel-group, single center trial. Adult patients undergoing laparoscopic fundoplication were recruited. The intervention group received 1 mg/kg intravenous lidocaine bolus prior to induction of anesthesia, then an intravenous infusion at 2 mg/kg/h for 24 hours. The primary outcome was pain, measured using a numeric rating scale for 30 hours postoperatively. Secondary outcomes were nausea and vomiting, opioid requirements, adverse events, serum lidocaine concentration, and length of hospital stay. The study was terminated after an interim analysis of 24 patients showed evidence of futility. There was no difference in postoperative pain scores (lidocaine versus control, mean ± standard deviation at rest (2.0 ± 2.7 vs 2.1 ± 2.4, P=0.286 or with movement (2.0 ± 2.6 vs 2.6 ± 2.7, P=0.487. Three adverse events occurred in the lidocaine group (25% of patients. Intravenous lidocaine did not provide clinically significant analgesia to patients undergoing laparoscopic fundoplication. The serum lidocaine concentration of patients who experienced adverse events were within the therapeutic range. This trial cannot confirm the safety of intravenous lidocaine at the dose tested.

    When administered near the time of training, protein synthesis inhibitors such as anisomycin impair later memory. A common interpretation of these findings is that memory consolidation requires new protein synthesis initiated by training. However, recent findings support an alternative interpretation that abnormally large increases in neurotransmitter release after injections of anisomycin may be responsible for producing amnesia. In the present study, a local anesthetic was administered prior to anisomycin injections in an attempt to mitigate neurotransmitter actions and thereby attenuate the resulting amnesia. Rats received lidocaine and anisomycin injections into the amygdala 130 and 120 min, respectively, prior to inhibitory avoidance training. Memory tests 48 hr later revealed that lidocaine attenuated anisomycin-induced amnesia. In other rats, in vivo microdialysis was performed at the site of amygdala infusion of lidocaine and anisomycin. As seen previously, anisomycin injections produced large increases in release of norepinephrine in the amygdala. Lidocaine attenuated the anisomycin-induced increase in release of norepinephrine but did not reverse anisomycin inhibition of protein synthesis, as assessed by c-Fos immunohistochemistry. These findings are consistent with past evidence suggesting that anisomycin causes amnesia by initiating abnormal release of neurotransmitters in response to the inhibition of protein synthesis.

    Full Text Available BACKGROUND: Lidocaine, an antiarrhythmic drug has been shown to be effective against post-ischaemic reperfusion injury in heart. However, its effect on pulmonary reperfusion injury has not been investigated. AIMS: We investigated the effects of lidocaine on a postischaemic reperfused rat lung model. MATERIALS AND METHODS: Lungs were isolated and perfused at constant flow with Krebs-Henseilet buffer containing 4% bovine serum albumin, and ventilated with 95% oxygen mixed with 5% CO2. Lungs were subjected to ischaemia by stopping perfusion for 60 minutes followed by reperfusion for 10 minutes. Ischaemia was induced in normothermic conditions. RESULTS: Postischaemic reperfusion caused significant (p < 0.0001 higher wet-to-dry lung weight ratio, pulmonary arterial pressure and peak airway pressure compared to control lungs. Lidocaine, at a dose of 5mg/Kg b.w. was found to significantly (p < 0.0001 attenuate the increase in the wet-to-dry lung weight ratio, pulmonary arterial pressure and peak airway pressure observed in post-ischaemic lungs. CONCLUSION: Lidocaine is effective in preventing post-ischaemic reperfusion injury in isolated, perfused rat lung.

    Full Text Available BACKGROUND Episiotomy is a most common surgical procedure for parturients during vaginal delivery. The problem encountered with episiotomy is pain, which is maximum during first 24 hours and may be severe enough to disturb the puerperium. This study aims to compare analgesic efficacy of analgesics, ropivacaine and lidocaine for perineal infiltration during episiotomy. MATERIALS AND METHODS We conducted a randomised double blind study for a period one year from August 2013 in a tertiary hospital. 100 parturients were included. RESULTS Ropivacaine 0.75% compared to lidocaine 2% did not show any statistical significant changes at suturing and after 4 hours; however, there were great statistically significant changes in VAS scores after 8 hours, 12 hours, 24 hours of episiotomy suturing. Ropivacaine group did not require systemic analgesics for 24 hours, but lidocaine group required systemic analgesics after 4 hours of suturing. Both groups (Ropivacaine and Lidocaine did not have any adverse effects. CONCLUSION Ropivacaine can be used safely for episiotomy wound infiltration thereby reducing the need for systemic analgesia.

    Ethamsylate, tramadol and lidocaine, partly excreted by the kidney, are generally used as hemostatic, analgesic and local anesthetic in surgery. We developed a simple and sensitive method for their simultaneous monitoring in human urine based on CE coupled with electrochemiluminescence detection by end-column mode. Under optimized conditions the proposed method yielded linear ranges from 5.0 x 10(-8) to 5.0 x 10(-5), 1.0 x 10(-7) to 1.0 x 10(-4) and 1.0 x 10(-7) to 1.0 x 10(-4) M with LODs of 8.0 x 10(-9) M (36 amol), 1.6 x 10(-8) M (72 amol) and 1.0 x 10(-8) M (45 amol) (S/N = 3) for ethamsylate, tramadol and lidocaine, respectively. The RSD for their simultaneous detection at 1.0 x 10(-6) M was 2.1, 2.8 and 3.2% (n = 7), respectively. For practical application an extraction step with ethyl acetate at pH 11 was performed to eliminate the influence of the sample ionic strength. The recoveries of ethamsylate, tramadol and lidocaine at different levels in human urine were between 87 and 95%. This method was used for simultaneous detection of ethamsylate, tramadol and lidocaine in clinic urine samples from two medicated patients. It was valuable in clinical and biochemical laboratories for monitoring these drugs for various purposes.

    Lipid based nanoparticles have become a major research object in topical drug delivery to enable drugs to pass the stratum corneum and reach the desired skin layer. The present investigation deals with the encapsulation of lidoacine into nanostructured lipid carriers (NLCs) and nanoethosomes for improving its dermal delivery and consequently local anesthetic efficacy. Concurrently these two topical delivery systems were compared. Lidocaine-loaded NLCs and nanoethosomes were characterized by various techniques and used for an in vitro skin penetration study using excised rat skin and Franz diffusion cells. The nanoparticles were tracked in the skin by following the Rhodamine-labled nanocarriers under fluorescent microscopy. Optimized lidocaine-loaded NLCs (size 96 nm, zeta potential -13.7 mV, encapsulation efficiency (EE) % 69.86% and loading capacity (LC) % 10.47%) and nanoethosomes (size 105.4 nm, zeta potential -33.6 mV, EE 40.14% and LC 8.02%) were chosen for a skin drug delivery study. Higher skin drug deposition of NLCs and nanoethosomal formulations compared to lidocaine hydroalcoholic solution represented a better localization of the drug in the skin. NLC formulation showed the lowest entered drug in the receptor phase of Franz diffusion cell in comparison with nanoethosomes and hydroalcoholic solution confirming the highest skin accumulation of drug. Both colloidal systems showed superiority over the drug solution for dermal delivery of lidocaine, however, NLC exhibited more promising characteristics than nanoethosomes regarding drug loading and skin targeted delivery.

    The effect of halothane on A-V conduction was evaluated in gods during atrial pacing using the technique of His-bundle electrocardiography. In addition, the effects of lidocaine and diphenylkydantoin (DPH) on A-V conuction were examined during halothane anesthesia. Effects of these drugs on three subintervals of A-V conduction were compared. These included the -H (stimulus atifact of His-bundle deflection-atrioventricular conduction), H-Q (His-budnle deflection onset of QRS complex-His-Purkinje conduction), and H-S intervals(His-bundle delfection to end of QRS COmplex-total intraventricular conduction). Linear regression best described the relationship between duration of interval (P-H, H-V,and H-S) and heart rate during incremental increases in the atrial paced rate. Data from these experiments were fitted to a multiple lenear regression model that predicted the effect of increasing concentrations of halothan, lidocaine, and DPH on slope and intercept coefficients. In creasing concentrations of halothan ( 30 and 45 mg/100 ml arterial). Both lidocaine and DPH further depressed conduction at all levels of halothan anesthesia. The P-H interval was particularly sensitive todrug effefts. This may represent potentiation of the normal slowing of conduction through the AVnode in response to incremental increases in heart rate (fatigue response.) We conclude thatboth lidocaine and DPH fail to reverse the depressant effect of halothane on A-V conduction. This may explain their ineffectiveness in treating certain types of arrhythmias during halothane anesthesia.

    No study has compared lidocaine with articaine, each at a concentration of 4% and combined with epinephrine. The purpose of this study was to compare the effectiveness of 4% lidocaine with that of 4% articaine, with a concentration of 1:100,000 epinephrine added to each, in an inferior alveolar nerve block for surgery on impacted lower third molars. This study was conducted at the Faculty of Dentistry, Mahidol University in Bangkok, Thailand. The randomized, single-blind, comparative split-mouth study was carried out in patients with symmetrically impacted lower third molars, as identified on panoramic radiographs. Each patient underwent surgery for the removal of the lower third molars by the same surgeon under local anesthesia at two separate visits, 3 weeks apart. The onset and duration of local anesthesia, intra-operative pain, surgical duration, and number of additional anesthetics administered were recorded. The subjective and objective onset of action for the local anesthetics showed statistically significant differences (P inferior alveolar nerve block was clinically more effective in the onset of subjective and objective anesthesia as compared with the use of 4% lidocaine. Based on the pain scores from the visual analogue scale, 4% lidocaine provided more analgesia during the procedure, and patients noted less intra-operative pain than with 4% articaine; however, the difference was not clinically significant.

    Ana M Valentim

    Full Text Available The increasing use of zebrafish model has not been accompanied by the evolution of proper anaesthesia for this species in research. The most used anaesthetic in fishes, MS222, may induce aversion, reduction of heart rate, and consequently high mortality, especially during long exposures. Therefore, we aim to explore new anaesthetic protocols to be used in zebrafish by studying the quality of anaesthesia and recovery induced by different concentrations of propofol alone and in combination with different concentrations of lidocaine.In experiment A, eighty-three AB zebrafish were randomly assigned to 7 different groups: control, 2.5 (2.5P, 5 (5P or 7.5 μg/ml (7.5P of propofol; and 2.5 μg/ml of propofol combined with 50, (P/50L, 100 (P/100L or 150 μg/ml (P/150L of lidocaine. Zebrafish were placed in an anaesthetic water bath and time to lose the equilibrium, reflex to touch, reflex to a tail pinch, and respiratory rate were measured. Time to gain equilibrium was also assessed in a clean tank. Five and 24 hours after anaesthesia recovery, zebrafish were evaluated concerning activity and reactivity. Afterwards, in a second phase of experiments (experiment B, the best protocol of the experiment A was compared with a new group of 8 fishes treated with 100 mg/L of MS222 (100M.In experiment A, only different concentrations of propofol/lidocaine combination induced full anaesthesia in all animals. Thus only these groups were compared with a standard dose of MS222 in experiment B. Propofol/lidocaine induced a quicker loss of equilibrium, and loss of response to light and painful stimuli compared with MS222. However zebrafish treated with MS222 recovered quickly than the ones treated with propofol/lidocaine.In conclusion, propofol/lidocaine combination and MS222 have advantages in different situations. MS222 is ideal for minor procedures when a quick recovery is important, while propofol/lidocaine is best to induce a quick and complete anaesthesia.

    In studying calcium paradox, perfused rat hearts were used to investigate the myocardial protective effects of lidocaine. Intracellular contents of phosphates were measured using the 31 P-NMR method. In hearts reexposed to calcium, following 3 minute calcium-free perfusion, a rapid contracture occurred, followed by rapid and complete disappearance of intracellular phosphates with no resumption of cardiac function. In hearts where lidocaine was administered from the onset of the calcium-free perfusion until 2 minutes following the onset of reexposure to calcium, both intracellular phosphates and cardiac contractility were maintained. Therefore, it can be said that cell membranes were protected by lidocaine

    Comparison of dexketoprofen and paracetamol added to the lidocaine in Regional Intravenous Anesthesia in terms of hemodynamic effects, motor and sensorial block onset times, intraoperative VAS values, and analgesia requirements. The files of 73 patients between 18 and 65 years old in the ASA I-II risk group who underwent hand and forearm surgery were analyzed and 60 patients were included in the study. Patients were divided into 3 groups: Group D (n = 20), 3 mg/kg 2% lidocaine and 50 mg/2 mL dexketoprofen trometamol; Group P (n = 20), 3 mg/kg 2% lidocaine and 3 mg/kg paracetamol; Group K (n = 20), 3 mg/kg 2% lidocaine. Demographic data, motor and sensorial block times, heart rate, mean blood pressure, VAS values, and intraoperative and postoperative analgesia requirements were recorded. Sensorial and motor block onset durations of Group K were significantly longer than other groups. Motor block termination duration was found to be significantly longer in Group D than in Group K. VAS values of Group K were found higher than other groups. There was no significant difference in VAS values between Group D and Group P. Analgesia requirement was found to be significantly more in Group K than in Group P. There was no significant difference between the groups in terms of heart rates and mean arterial pressures. We concluded that the addition of 3 mg/kg paracetamol and 50 mg dexketoprofen to lidocaine as adjuvant in Regional Intravenous Anesthesia applied for hand and/or forearm surgery created a significant difference clinically.

    Full Text Available Introduction & Objective: ESWL is a non-invasive method of breaking stones, using acoustic shock waves. Shock waves cause temporary deep visceral pain and discomfort in entry therefore, administration of sedatives is necessary. The purpose of this study was to compare the effect of topical lidocaine and piroxicam gel with intravenous pethidine in reducing pain during ESWL. Materials & Methods: This clinical trial study was performed on 159 patients who referred to Ayatollah Kashani Hospital in Shahrkord for ESWL in 2009. Patients were randomly divided into three-groups. For the first group, intravenous pethidine (0.5 mg/kg alone was administered. The second group received topical piroxicam, and the third group received topical lidocaine in the area of flank for half an hour before ESWL. During the operation, those patients who had unbearable pain, received another 0.5 mg/kg of pethidine. Data was collected using MC Gill questionnaires and analyzed using the SPSS software, using parametric, nonparametric methods and Dunn's Multiple Comparisons tests. Results: The mean of pain scores in the first group (pethidine was 6.2 ± 6.9 while these scores were 3.2 ± 2 .7 and 3.9 ± 3.1 for the second (piroxicam gel and third group (lidocaine gel respectively. The differences in the mean score of pain was significant in the pethidine group compared to the other groups (P <0.05. The average pethidin consumption were 24 ± 16 mg for the first group (pethidine, 10 ± 13 mg for the second group (piroxicam gel, and 5 ± 9 mg for the third group (lidocaine gel. The mean difference was significant in pethidine treated group in comparison with other two groups (P < 0.05. Conclusion: The use of topical piroxicam or lidocaine reduces pain in patients after ESWL It also reduces the need for sedative drugs.

    Propofol has been used for the induction and maintenance of anesthesia. However, patients experience vascular pain during its injection. The objective of this study was to compare the effect of the lipid type used in propofol preparations and that of lidocaine on the immediate and delayed vascular pain induced by propofol administration. In this double-blinded clinical study, 150 patients at American Society of Anesthesiologists level I-II were randomly divided into three equally sized groups. A propofol with medium and long-chain triglycerides (propofol-MCT/LCT) was administered to the first group. The second group received propofol containing propofol-LCT, and the third group received propofol-LCT and pretreatment lidocaine 20 mg. The incidence and the intensity of immediate (during injection) and delayed injection pain (after 20 s) were evaluated on a verbal analog scale (1-10) until patients' unconsciousness. Sample size was calculated with SigmaPlot version 12.5 software. Data were analyzed with Statistical Package for the Social Sciences (SPSS) version 16, one-way analysis of variance, and post-hoc Tukey. P < 0.05 was considered statistically significant. The demographic parameters of the three groups were similar. The lidocaine group experienced the least immediate vascular pain. The intensity of pain was highest in the propofol-LCT group (P = 0.04). Additionally, the intensity of delayed pain was lowest in the propofol-MCT/LCT group (P = 0.01). The incidence of pain associated with the propofol administration was 26.5, 44, and 18%, respectively, in propofol-MCT/LCT, propofol-LCT, and lidocaine and propofol-LCT groups. The results indicate an effect of the lipid type on delayed pain reduction, especially propofol-MCT/LCT. On the other hand, the lidocaine decreases immediate propofol-LCT vascular pain.

    Lidocaine has been shown to protect ischemic myocardium, but the degree of its effectiveness is not yet well established. Therefore, in this study, the effects of this drug on ultimate infarct size were examined quantitatively. Another member of the same class of drugs, droxicainide (ALS1249), DL-N-(2-hydroxyethyl)-pipecolinyl-2,6-dimethylanilide hydrochloride, is a new antiarrhythmic agent that has shown a good therapeutic index in the initial experimental studies. Accordingly, the effects of this drug on ultimate infarct size were examined and compared with those of lidocaine. Coronary artery occlusion was performed on 29 dogs. One minute later, technetium-99m labeled microspheres were injected into the left atrium for assessment of the hypoperfused zone (the zone at risk of infarction). Fifteen minutes after occlusion, the dogs were randomized into three groups: 9 dogs served as a control group, 10 were given lidocaine and 10 were given the same dosage of droxicainide. Six hours after occlusion, the dogs were sacrificed and the hearts cut into 3 mm thick slices and incubated in triphenyltetrazolium chloride to delineate the area of myocardial damage. Autoradiography of the same slices provided images of the areas of myocardial hypoperfusion. Thereafter, in each dog, the percent of hypoperfused area that evolved to necrosis was calculated. In control dogs, it was 85.6 +/- 2.0%; in lidocaine-treated dogs, 68.1 +/- 4.1% (p less than 0.01), a reduction of 20%; and in droxicainide-treated dogs, 50.1 +/- 5.3%, a reduction of 41% (p less than 0.001 versus control and p less than 0.005 versus lidocaine)

    Both clonidine and ketamine have been found to prolong the action of local anesthetics through a peripheral mechanism. Our study compares the efficacy of a low dose of clonidine or ketamine separately added to intravenous regional anesthesia (IVRA) with lidocaine to prevent tourniquet pain. We conducted a prospective randomized double-blinded study in 45 patients undergoing hand or forearm surgery, with anticipated duration exceeding 1 hour under IVRA. Proximal cuff inflation of a double tourniquet was followed by administration of 40 mL of lidocaine 0.5% and either saline, 1 microg/kg clonidine, or 0.1 mg/kg ketamine. When anesthesia was established, the inflation of the proximal and distal cuff was interchanged. Thereafter, tourniquet pain was rated on a visual analog scale (VAS) every 10 minutes. Intraoperatively, boluses of 25 microg fentanyl were provided for tourniquet pain treatment when required, and total fentanyl consumption was recorded. Patients receiving plain lidocaine persistently reported the highest pain scores among groups (P <.001) 20 minutes after distal cuff inflation. Differences between the groups with additional treatment were noted 50 minutes after distal cuff inflation and until the end of the observation, with significantly lower VAS ratings (P <.001 to P <.01) in ketamine-treated patients. Total fentanyl consumption was significantly decreased by ketamine (70.00 +/- 25.35 microg) or clonidine (136.67 +/- 39.94 microg) compared with the plain lidocaine group (215.33 +/- 52.33 microg) (P <.001 between all groups). The addition of clonidine 1 microg/kg or ketamine 0.1 mg/kg to lidocaine for IVRA delays the onset of unbearable tourniquet pain and decreases analgesic consumption for tourniquet pain relief, although ketamine has a more potent effect.

    Full Text Available Hiltrud Liedgens,1 Marko Obradovic,1 Mark Nuijten2 1Grunenthal GmbH, Aachen, Germany; 2Ars Accessus Medica, Amsterdam, the Netherlands Background: Post-herpetic neuralgia (PHN is the most common and most debilitating complication of herpes zoster, and involves considerable associated costs. Objective: This paper presents results from nine health economic studies undertaken in eight European countries that compared lidocaine medicated plaster with gabapentin and/or pregabalin in PHN. It aims to support the increasing need for published cost-effectiveness data for health care decision-making processes in Europe. Methods: All studies were based on a similar core Markov model with data derived from clinical trials, local Delphi panels, and official national price and tariff lists. The main outcome measure was cost per quality-adjusted life year gained; time without pain or intolerable adverse events was also included as a secondary outcome measure. All studies focused on an elderly population of patients with PHN who had insufficient pain relief with standard analgesics and could not tolerate or had contraindications to tricyclic antidepressants. Results: Despite considerable differences in many of the variables used, the results showed remarkable similarity and suggested that use of lidocaine medicated plaster offered cost-savings in many of the countries studied, where it proved a highly cost-effective alternative to both gabapentin and pregabalin. Conclusion: Lidocaine medicated plaster is a cost-effective alternative to gabapentin and pregabalin in the treatment of PHN. These savings are largely the result of the superior safety profile of the lidocaine medicated plaster. Keywords: post-herpetic neuralgia, zoster, cost-effectiveness, lidocaine, plaster

    Lidocaine and bupivacaine are commonly infiltrated into surgical cutaneous wounds to provide local anaesthesia after surgical procedures. However, very little is known about their effects on cutaneous wound healing. If an inhibitory effect is demonstrated, then the balance between the benefits of postoperative local anaesthesia and the negatives of impaired cutaneous wound healing may affect the decision to use local anaesthesia or not. Furthermore, if a difference in the rate of healing of lidocaine- and bupivacaine-treated cutaneous wounds is revealed, or if an inhibitory effect is found to be dose-dependent, then this may well influence the choice of agent and its concentration for clinical use. Immediately before incisional wounding, we administered lidocaine and bupivacaine intradermally to adult female mice, some of which had been ovariectomized to act as a model of post-menopausal women (like post-menopausal women, ovariectomized mice heal wounds poorly, with increased proteolysis and inflammation). Day 3 wound tissue was analysed histologically and tested for expression of inflammatory and proteolytic factors. On day 3 post-wounding, wound areas and extent of re-epithelialization were comparable between the control and local anaesthetic-treated animals, in both intact and ovariectomized groups. Both tested drugs significantly increased wound activity of the degradative enzyme matrix metalloproteinase-2 relative to controls, while lidocaine also increased wound neutrophil numbers. Although lidocaine and bupivacaine influenced local inflammatory and proteolytic factors, they did not impair the rate of healing in either of two well-established models (mimicking normal human wound healing and impaired age-related healing).

    Acupuncture is an ancient complementary medicine which is currently used worldwide. Many serious adverse events have been reported which include a spectrum of mild-to-fatal complications. However, the level of awareness with regard to complications is still low both to physicians and patients. We report a 63-year-old who presented with acute shortness of breath 2 hours after having had acupuncture. On examination, there was absent breath sound heard on the left lung and slightly reduced breath sound on the right lung. She had type 1 respiratory failure. Urgent chest radiograph confirmed bilateral pneumothorax which was more severe on the left with tension pneumothorax and mediastinal shift. Chest tubes were inserted bilaterally after failed needle aspiration attempts. Subsequently, the pneumothoraces resolved, and she was discharged well. The bilateral pneumothoraces caused by acupuncture were curable but could have been potentially fatal if diagnosis was delayed. This case report adds to the limited current literature on the complications of acupuncture leading to bilateral pneumothoraces. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Full Text Available Inverted papilloma (IP is a benign tumor of the nasal cavity and paranasal sinuses that is unilateral in most cases. Bilateral IP, involving both sides of the nasal cavity and sinuses, is extremely rare. This paper describes a large IP that filled in both sides of the nasal cavity and sinuses, mimicking association with malignancy. The tumor was successfully treated by bilateral endoscopic medial maxillectomy (EMM. The patient is without evidence of the disease 24 months after surgery. If preoperative diagnosis does not confirm the association with malignancy in IP, endoscopic sinus surgery (ESS should be selected, and ESS, including EMM, is a good first choice of the treatment for IP.

    Background Not much data are available on the natural history of bilateral renal agenesis, as the medical community does not typically offer aggressive obstetric or neonatal care asbilateral renal agenesis has been accepted as a lethal condition. Aim To provide an evidence-based, ethically justified approach to counseling pregnant women about the obstetric management of bilateral renal agenesis. Study design A systematic literature search was performed using multiple databases. We deploy an ethical analysis of the results of the literature search on the basis of the professional responsibility model of obstetric ethics. Results Eighteen articles met the inclusion criteria for review. With the exception of a single case study using serial amnioinfusion, there has been no other case of survival following dialysis and transplantation documented. Liveborn babies die during the neonatal period. Counseling pregnant women about management of pregnancies complicated by bilateral renal agenesis should be guided by beneficence-based judgment informed by evidence about outcomes. Conclusions Based on the ethical analysis of the results from this review, without experimental obstetric intervention, neonatal mortality rates will continue to be 100%. Serial amnioinfusion therefore should not be offered as treatment, but only as approved innovation or research. PMID:28222038

    It has been suggested that at equivalent therapeutic concentrations, lidocaine and bupivacaine may have different cardiotoxic potency. In the isolated working rat heart preparation, the effect of a range of lidocaine and bupivacaine concentrations on glucose uptake and lactate production (LP) were observed. Insulin was added, 10 ..mu../L, to Ringer's solution containing /sup 3/H-labeled glucose to measure the glycolytic flux (GF). The effect of the local anesthetics on LP at the indicated concentrations were similar. Lidocaine appears to depress the glycolytic flux from exogenous glucose to a lesser degree. Bupivacaine, 10 mg/L, depresses VO/sub 2/ to a greater degree than does lidocaine, 40 mg/L.

    Full Text Available OBJECTIVE: To evaluate the efficacy and safety of bilateral pallidotomies in five patients with generalized dystonia. BACKGROUND: Generalized dystonias are frequently a therapeutic challenge, with poor responses to pharmacological treatment. GPi (globus pallidus internus pallidotomies for Parkinson's disease ameliorate all kinds of dyskinesias/dystonia, and recent studies reported a marked improvement of refractory dystonias with this procedure. METHODS: Five patients with generalized dystonias refractory to medical treatment were selected; one posttraumatic and four idiopathic. The decision to perform bilateral procedures was based on the predominant axial involvement in these patients. Dystonia severity was assessed with the Burke-Fahn-Marsden Dystonia Scale (BFM. Simultaneous procedures were performed in all but one patient, who had a staged procedure. They were reevaluated with the same scale (BFM by an unblinded rater at 1, 2, 3, 30, 60, 90, 120 and 180 days post-operatively. RESULTS: The four patients with idiopathic dystonia showed a progressive improvement up to three months; the patient with posttraumatic dystonia relapsed at three months. One patient had a marked improvement, being able to discontinue all the medications. A mean decrease in the BFM scores of 52,58% was noted. One patient had a trans-operative motor seizure followed by a transient hemiparesis secondary to rack hemorrhage; other was lethargic up to three days after the procedure. CONCLUSIONS: Our results show that bilateral GPi pallidotomies may be a safe and effective approach to medically refractory generalized dystonias; it can also be speculated that the posttraumatic subgroup may not benefit with this procedure.As distonias generalizadas são freqüentemente um desafio terapêutico, com pobres respostas aos tratamentos farmacológicos.

    Bronchoscopy is generally a safe procedure, but the induction of anaesthesia can induce bronchospasm. Consequently we investigated the influence of propofol, remifentanil and lidocaine on the tone of the human bronchial smooth muscle. The influence of propofol, remifentanil and lidocaine on the contractile response of human bronchial smooth muscle to electrical field stimulation (EFS) has been evaluated. The role of capsaicin-sensitive sensory nerves and of inducible nitric oxide synthase has also been assessed. Furthermore, the interaction between these three dugs has been measured by Bliss Independence (BI) theory. Statistical significance (P < 0.05) was assessed by Student's t test or ANOVA. Propofol (1.3 μg ml(-1)) and lidocaine (1 mg ml(-1)) reduced the baseline tone of bronchial rings (-14.45 ± 4.53% and -33.40 ± 1.07%, respectively, P < 0.05), whereas remifentanil had not such effect. Aminoguanidine prevented the relaxant effect of propofol. Propofol did not alter the bronchial contractile response to EFS following 30 min of treatment, whereas remifentanil enhanced the bronchial tension (133.83 ± 9.38%, control 101.93 ± 6.82%, P < 0.05 P < 0.05) and lidocaine completely abolished the contractility at 1 mg ml(-1) (P < 0.05). The desensitization of capsaicin-sensitive sensory nerves normalized the hyperresponsiveness induced by remifentanil (-26.77 ± 1.68%, P < 0.05). Significant BI antagonism (P < 0.001) was detected for propofol and lidocaine on the bronchial hyperresponsiveness induced by remifentanil. Propofol and remifentanil may be used safely for bronchoscopy, although remifentanil should be associated with propofol or lidocaine to prevent the potential opioid-mediated bronchospasm.

    Lidocaine hydrochloride ophthalmic gel is a novel ophthalmic preparation for topical ocular anesthesia. The study is aimed at evaluating the ocular and systemic pharmacokinetics of lidocaine hydrochloride 3.5 % ophthalmic gel in rabbits after ocular topical administration. Thirty-six rabbits were randomly placed in 12 groups (3 rabbits per group). The rabbits were quickly killed according to their groups at 0 (predose), 0.0833, 0.167, 0.333, 0.667, 1, 1.5, 2, 3, 4, 6, and 8 h postdose and then the ocular tissue and plasma samples were collected. All the samples were analyzed by a validated LC-MS/MS method. The test result showed that the maximum concentration (C max) of lidocaine in different ocular tissues and plasma were all achieved within 20 min after drug administration, and the data of C max were (2,987 ± 1814) μg/g, (44.67 ± 12.91) μg/g, (26.26 ± 7.19) μg/g, (11,046 ± 2,734) ng/mL, and (160.3 ± 61.0) ng/mL for tear fluid, cornea, conjunctiva, aqueous humor, and plasma, respectively. The data of the elimination half-life in these tissues were 1.5, 3.2, 3.5, 1.9, and 1.7 h for tear fluid, cornea, conjunctiva, aqueous humor, and plasma, respectively. The intraocular lidocaine levels were significantly higher than that in plasma, and the elimination half-life of lidocaine in cornea, conjunctiva, and aqueous humor was relatively longer than that in tear fluid and plasma. The high intraocular penetration, low systemic exposure, and long duration in the ocular tissues suggested lidocaine hydrochloride 3.5 % ophthalmic gel as an effective local anesthetic for ocular anesthesia during ophthalmic procedures.

    We report on the use of intravenous (IV) high-dose lidocaine to relieve diabetic neuropathic pain, and the technique's effects on clinical measures of lipid peroxidation. Under continuous electrocardiogram monitoring, IV lidocaine (5 mg kg(-1) in 100 mL saline) was administered over 30 minutes to 7 non-insulin-dependent diabetic patients suffering from neuropathic pain who reported increased pain within the preceding 6 months. This treatment was performed once a week for 1 month. Blood samples were collected from the contralateral limb to determine plasma superoxide dismutase (SOD) and malondialdehyde (MDA) levels on admission and following the final lidocaine administration. Plasma MDA concentrations significantly decreased after the final IV lidocaine treatment (P < .05, paired t-test), whereas SOD levels did not show a statistically significant difference compared with baseline levels. High-dose lidocaine treatment lessens MDA levels, a marker of free-radical-mediated cell damage. This suggests that one of lidocaine's mechanism of action may be its effect on oxygen free radicals, which in turn impacts lipid peroxidation.

    Our aim was to evaluate the efficacy of clonidine with lidocaine as a local anaesthetic agent for inferior alveolar mandibular nerve blocks for dental extraction. We studied 200 patients who required extraction of mandibular teeth and divided them into two groups of 100 each, the first of which was given lidocaine and adrenaline (12.5μg/ml) and the second lidocaine and clonidine (15μg/ml). Cardiovascular vascular variables (blood pressure, heart rate, and mean arterial pressure) were assessed before, during, and after extraction, and postoperative pain was measured on a visual analogue scale. There was a significant reduction in systolic blood pressure (p=0.0001) and heart rate (p=0.000) after injection of clonidine. However, they both increased after injections of lidocaine plus adrenaline, and there was a significant reduction in pain at four hours postoperatively with clonidine (p=0.000). Our results showed that anaesthesia with lidocaine and clonidine decreases systolic blood pressure and heart rate 10minutes after injection for extraction of lower mandibular teeth. We suggest that patients who have local anaesthetic with lidocaine and clonidine are at minimal cardiovascular risk and there is no difference in the onset of anaesthesia.

    With the emphasis on bilateral hearing nowadays, bilateral cochlear implantation has been tried out for bilateral aural rehabilitation. Bilateral sensorineural hearing loss caused by head trauma can get help from cochlear implantation. We present the case of a 44-year-old man with bilateral otic capsule violating temporal bone fractures due to head trauma. The patient demonstrated much improved audiometric and psychoacoustic performance after bilateral cochlear implantation. We believe bilateral cochlear implantation in such patient can be a very effective tool for rehabilitation. Copyright © 2011 Elsevier Inc. All rights reserved.

    A novel mucoadhesive buccal tablet containing flurbiprofen (FLB) and lidocaine HCl (LID) was prepared to relieve dental pain. Tablet formulations (F1-F9) were prepared using variable quantities of mucoadhesive agents, hydroxypropyl methyl cellulose (HPMC) and sodium alginate (SA). The formulations were evaluated for their physicochemical properties, mucoadhesive strength and mucoadhesion time, swellability index and in vitro release of active agents. Release of both drugs depended on the relative ratio of HPMC:SA. However, mucoadhesive strength and mucoadhesion time were better in formulations, containing higher proportions of HPMC compared to SA. An artificial neural network (ANN) approach was applied to optimise formulations based on known effective parameters (i.e., mucoadhesive strength, mucoadhesion time and drug release), which proved valuable. This study indicates that an effective buccal tablet formulation of flurbiprofen and lidocaine can be prepared via an optimized ANN approach.

    Allergic reactions to local anesthetics are very rare and represent inhalation lung injury due to butane gas fuel. On the fifth day, he developed an asthmatic attack and anaphylactic shock immediately after lidocaine aerosol administration to prepare for bronchoscopy to confirm an acute inhalational lung injury diagnosis. Cardiopulmonary resuscitation was performed immediately after respiratory arrest, and the patient was admitted to the intensive care unit intubated and on a ventilator. He was extubated safely on the third post-cardiopulmonary resuscitation day. These observations suggest that aerosol lidocaine anesthesia may cause airway narrowing and anaphylactic shock. Practitioners should be aware of this potential complication. We report on this case with a brief review of the literature.

    Full Text Available Abstract Background and objectives Reducing pain on injection of anesthetic drugs is of importance to every anesthesiologist. In this study we pursued to define if pretreatment by granisetron reduces the pain on injection of etomidate similar to lidocaine. Methods Thirty patients aged between 18 and 50 years of American Society of Anesthesiologists physical status class I or II, whom were candidates for elective laparoscopic cholecystectomy surgery were enrolled in this study. Two 20 gauge cannulas were inserted into the veins on the dorsum of both hands and 100 mL of normal saline was administered during a 10 min period from each cannula. Using an elastic band as a tourniquet, venous drainage of both hands was occluded. 2 mL of granisetron was administered into one hand and 2 mL of lidocaine 2% at the same time into the other hand. One minute later the elastic band was opened and 2 mL of etomidate was administered to each hand with equal rates. The patients were asked to give a score from 0 to 10 (0 = no pain, 10 = severe pain to each the pain sensed in each hand. Results Two patients were deeply sedated after injection of etomidate and unable to answer any questions. The mean numerical rating score for injection pain of intravenously administered etomidate after intravenous granisetron was 2.3 ± 1.7, which was lower when compared with pain sensed due to intravenously administered etomidate after administration of lidocaine 2% (4.6 ± 1.8, p < 0.05. Conclusion The result of this study demonstrated that, granisetron reduces pain on injection of etomidate more efficiently than lidocaine.

    Alveolitis is considered a disturbance of the alveolar healing process that is characterized by blood clot disintegration, alveolar wall infection and extreme pain. Several substances have been investigated to improve healing and guarantee postoperative comfort to patients. The aim of this study was to evaluate, microscopically, in rats, the healing process in non-infected tooth sockets, after application of a 10% metronidazole and 2% lidocaine dressing, using lanolin as vehicle and mint as flavoring. Forty-five rats (Rattus norvegicus albinus, Wistar) had their right incisor extracted and were randomly assigned to 3 groups (n=15): Group I (control): the sockets were filled with blood clot; Group II: application of adrenaline solution at 1:1 000 with an absorbent paper point during 1 min plus filling of the socket with a 10% metronidazole and 2% lidocaine dressing, with lanolin as vehicle, and mint as flavoring; Group III: filling of the socket with the 10% metronidazole and 2% lidocaine dressing, with lanolin as vehicle and mint as flavoring. After 6, 15 and 28 days postoperatively, 5 animals per group were euthanized with an injectable anesthetic overdose. Histological and statistical analyses were performed. The results showed that the 10% metronidazole and 2% lidocaine dressing with lanolin as vehicle and mint as flavoring yielded similar response as that of the normal repair group and may be used to prevent the onset of alveolitis in those cases in which any predisposing factor is present. The use of this dressing has shown a good postoperative patient's comfort and does not cause a significant delay in the alveolar healing process.

Sedation was performed with midazolam at a total dose of 3 mg and topical anesthesia with 0.5% proxymetacaine chlorhydrate and 2% lidocaine gel combined with 2% lidocaine by intracameral route. The intraoperative vital parameters, scores based on the Iowa Satisfaction with Anesthesia Scale (ISAS, and the pain visual analog scale (VAS were recorded at several time points after surgery. RESULTS: A total of 106 patients were enroled in study (73.6% female, the mean age was 65.9 years. The surgical procedures lasted 11.2 minutes on average. The hemodynamic parameters did not exhibit significant changes at any of the investigated time points. The average ISAS score was 2.67 immediately after surgery and 2.99 eight hours after the surgery; this increase was statistically significant (p<0.0001. More than two-thirds (68.9% of the participants (73 patients did not report any pain in the transoperative period, and 98.1% of patients denied the occurrence of pain after surgery. CONCLUSIONS: Patients that received topical anesthesia supplemented by intracameral lidocaine combined with sedation for phacoemulsification cataract surgery reported adequate level of satisfaction with the anesthetic

    To compare the effectiveness of pain relief of Sucralfate and lidocain antacid 50:50 solution in post esophageal variceal band ligation pain. All patients who had under gone Esophageal Variceal Band Ligation (EVBL) were included in the study. Patients un-willing to be included in the study or those who didn't have post EVBL pain were excluded. Patients with post EVBL pains were divided into two groups: one group was given sucralfate and other was given lidocaine: antacid 50:50 solution. Both were inquired about the duration of the pain relief after the medication. The results were analyzed on SPSS 23. Independent samples T-test was performed to find out whether the difference in duration of pain relief was significantly different in the two groups. Out of 110 patients who have EVBL, 66(60.00%) had pain and 44(40.00%) were pain free. In the pain group 46 (69.7%) were given sucralfate and 20 (30.3%) were given lidocain: antacid 50:50 solution. Mean duration of pain relief in two groups was 2.78 (SD ± 2.096) and 2.5 days (SD ±. 0.76) respectively. Independent samples T-test results revealed that there was no statistically significant difference in the duration of pain relief between these two groups with p value 0.426. Both Sucralfate and Lidocain: antacid 50:50 solutions are effective in relieving the post EVBL pain. However, no statistically significant difference in duration of pain relief was detected in separate groups of patients treated with either treatment.

    The duration of spinal anesthesia with bupivacaine is often too long for day surgery. A recent study of patients presenting for transurethral surgery suggested that the addition of a small amount of lidocaine to intrathecal hyperbaric bupivacaine could shorten the duration of the sensory and moto...... blocks. In this prospective, randomized double-blind study we investigated these findings in patients undergoing unilateral knee arthroscopy....

    Lip augmentation with hyaluronic acid fillers is established. As monophasic polydensified hyaluronic acid products with variable density, CPM-HAL1 (Belotero Balance Lidocaine, Merz Aesthetics, Raleigh, NC) and CPM-HAL2 (Belotero Intense Lidocaine, Merz Aesthetics, Raleigh, NC) are qualified for beautification and particularly natural-looking rejuvenation, respectively. The aim of this article was to assess the handling and outcome of lip augmentation using the lidocaine-containing hyaluronic acid fillers, CPM-HAL1 and CPM-HAL2. Data were documented from patients who received lip augmentation by means of beautification and/or rejuvenation using CPM-HAL1 and/or CPM-HAL2. Observation period was 4 months, with assessment of natural outcome, evenness, distribution, fluidity, handling, malleability, tolerability, as well as patient satisfaction and pain. A total of 146 patients from 21 German centers participated. Physicians rated natural outcome and evenness as good or very good for more than 95% of patients. Distribution, fluidity, handling, and malleability were assessed for both fillers as good or very good in more than 91% of patients. At every evaluation point, more than 93% of patients were very or very much satisfied with the product. A total of 125 patients (85.6%) experienced transient injection-related side effects. Pain intensity during the procedure was mild (2.72 ± 1.72 on the 0-10 pain assessment scale) and abated markedly within 30 minutes (0.42 ± 0.57). Lip augmentation with hyaluronic acid fillers produced a long-term cosmetic result. Due to the lidocaine content, procedural pain was low and transient. Accordingly, a high degree of patient satisfaction was achieved that was maintained throughout the observation period. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    1982-09-01

    A cohort study of neonatal mortality (N = 106) in white singleton births (N = 14,486) in Utah for January-June 1975 was conducted. Using membership and activity in the Church of Jesus Christ of Latter-day Saints (LDS or Mormon) as a proxy for parental health practices, i.e., tobacco and alcohol abstinence, differential neonatal mortality rates were calculated. The influence of potential confounding factors was evaluated. Low activity LDS members were found to have an excess risk of neonatal death five times greater than high activity LDS, with an upper bound of a two-sided 95% confidence interval of 7.9. The data consistently indicate a lower neonatal mortality rate for active LDS members. Non-LDS were found to have a lower rate than either medium or low activity LDS.

    Full Text Available The past 2-3 decades have seen dramatic changes in the approach to pain management in the neonate. These practices started with refuting previously held misconceptions regarding nociception in preterm infants. Although neonates were initially thought to have limited response to painful stimuli, it was demonstrated that the developmental immaturity of the central nervous system makes the neonate more likely to feel pain. It was further demonstrated that untreated pain can have long-lasting physiologic and neurodevelopmental consequences. These concerns have resulted in a significant emphasis on improving and optimizing the techniques of analgesia for neonates and infants. The following article will review techniques for pain assessment, prevention, and treatment in this population with a specific focus on acute pain related to medical and surgical conditions.

    2010-08-01

    Full Text Available OBJECTIVE: Local anesthetic solutions with vasoconstrictors are not contraindicated in hypertensive patients, but due to their hemodynamic effects, local anesthetics without vasoconstrictors are mainly preferred by the clinicians. The aim of this study was to compare hemodynamic effects of three different local anesthetics without vasoconstrictors during tooth extraction in hypertensive patients. MATERIAL AND METHODS: Sixty-five mandibular molars and premolars were extracted in 60 hypertensive patients (29 females and 31 males; mean age: 66.95 ± 10.87 years; range: 38 to 86 years old. Inferior alveolar and buccal nerve blocks were performed with 2% lidocaine hydrochloride (HCl, 2% prilocaine HCl or 3% mepivacaine HCl without vasoconstrictor. Hemodynamic parameters namely systolic blood pressure (SBP, diastolic blood pressure (DBP, mean arterial pressure (MAP, heart rate (HR, saturation rate (SR, rate pressure product (RPP and pressure rate quotient (PRQ were investigated before and at different intervals after anesthetic injection. RESULTS: The hemodynamic effects of the three agents were similar to each other, although some significance was observed for DBP, MAP, RPP and PRQ values in the lidocaine, prilocaine and mepivacaine groups. CONCLUSION: Lidocaine, prilocaine and mepivacaine solutions without vasoconstrictor can be safely used in hypertensive patients. It is advisable that dental practitioners select anesthetic solutions for hypertensive patients considering their cardiovascular effects in order to provide patient comfort and safety.

    Full Text Available The effects of intravenous (i.v. lidocaine, dexmedetomidine and their combination delivered as a bolus followed by a constant rate infusion (CRI on the minimum alveolar concentration of isoflurane (MACISO in dogs were evaluated. Seven healthy adult dogs were included. Anaesthesia was induced with propofol and maintained with isoflurane. For each dog, baseline MAC (MACISO/BASAL was determined after a 90-minute equilibration period. Thereafter, each dog received one of the following treatments (loading dose, CRI: lidocaine 2 mg kg(-1, 100 µg kg(-1 minute(-1; dexmedetomidine 2 µg kg(-1, 2 µg kg(-1 hour(-1; or their combination. MAC was then determined again after 45- minutes of treatment by CRI. At the doses administered, lidocaine, dexmedetomidine and their combination significantly reduced MACISO by 27.3% (range: 12.5-39.2%, 43.4% (33.3-53.3% and 60.9% (46.1-78.1%, respectively, when compared to MACISO/BASAL. The combination resulted in a greater MACISO reduction than the two drugs alone. Their use, at the doses studied, provides a clinically important reduction in the concentration of ISO during anaesthesia in dogs.

    Two new analogues of lidocaine were synthesized at the College of Pharmacy, King Saud University: compound I (Methyl-2-[2-(N,N-diethylamino) acetamido]-3-cyano-4,5-dimethylbenzoate) and compound II (Methyl-2-[2-(piperidino) acetamido]-3-cyano-4,5-dimethylbenzoate). Their influence on the arterial blood pressure and the heart rate of urethane-anaesthetized rats was studied and compared with the actions of lidocaine. Compounds I, II and lidocaine induced significant dose-dependent decreases in the arterial blood pressure and heart rate, which usually returned to basal values within 3-5 min. There were significant differences in the potency of the three compounds in producing their effects on blood pressure and heart rate (Plidocaine and compound I, respectively. The results of this study also indicated the ineffectiveness of antagonists of autonomic, histaminergic and 5-HT receptor, and various vasodilators in blocking the actions of the three compounds on blood pressure and heart rate. Pretreatment with CaCl(2)significantly reduced the hypotension and bradycardia induced by the three compounds, suggesting the involvement of calcium channels, probably of the L type. Several possible mechanisms are postulated. In conclusion, the results direct attention to the capability of the two new compounds to decrease blood pressure and heart rate; affects that may have clinical potential.

We compared the anesthetic effect of lidocaine HCL (2% by manipulating the current parameters on 21 healthy volunteers (age: 21.2 ± 4.2, height 170.7 ± 10.2 cm, mass 82.1 ± 19.2 kg. Three conditions were administered in a random order using a Phoresor II® with 2 mL, 2% lidocaine HCL in an iontophoresis electrode. (1 HASD (40 mA*min: High amplitude (4 mA, short duration (10 min; (2 LALD (40 mA.min: Low amplitude (2 mA, long duration (20 min; (3 Sham condition (0 mA, 20 min. Semmes-Weinstein monofilament (SWM scores were taken pre and post intervention to measure sensation changes. Two-way ANOVA with repeated measures was used to compare sensation. Both iontophoresis treatments: LALD (4.2 ± 0.32 mm and HASD (4.2 ± 0.52 mm significantly increased SWM scores, indicating an increase in anesthesia, compared to the sham condition (3.6 ± 0.06 mm p < 0.05. Neither LALD nor HASD was more effective and there was no difference in anesthesia with the sham. Lidocaine delivered via iontophoresis reduces cutaneous sensation. However, there was no benefit in either a HASD or LALD treatment.

    Fentanyl is frequently used during anesthesia induction. The use of fentanyl can cause cough through different mechanisms. Here, we aimed to investigate effects of pheniramine maleate (PM), an antihistaminic agent, and compare it with lidocaine on fentanyl induced cough. This is a randomized double-blind prospective clinical study of ASA I-II, 120 patients scheduled for elective abdominal surgery. Patients were administered drugs intravenously and randomly allocated into three groups: Group C (2 ml 0.9 % normal saline), Group L (1mg/kg lidocaine), and Group F (PM 45.5 mg). 90 seconds after administration, 2µ/kg fentanyl was applied in three seconds to all patients. Severity of cough (mild: 1-2, moderate: 3-5, severe> 5), time of the cough and vital parameters were recorded 90 seconds after fentanyl injection. Eight patients (25%) in Group C had fentanyl induced cough whereas three patients (7.5%) in Group L and one patient (2.5%) in Group F experienced this phenomenon. There was statistically significant difference between Group F and Group C (p0.05). Pheniramine Maleate 45.5 mg is better that placebo and as effective as lidocaine to prevent fentanyl induced cough.

    Concerning a hydraulic bilateral construction robot, its system constitution, structures and functions of important components, and the results of some tests are explained, and the researches conducted at Gifu University are described. The construction robot in this report is a servo controlled system of a version developed from the mini-shovel now available in the market. It is equipped, in addition to an electrohydraulic servo control system, with various sensors for detecting the robot attitude, vibration, and load state, and with a camera for visualizing the surrounding landscape. It is also provided with a bilateral joy stick which is a remote control actuator capable of working sensation feedback and with a rocking unit that creates robot movements of rolling, pitching, and heaving. The construction robot discussed here, with output increased and response faster thanks to the employment of a hydraulic driving system for the aim of building a robot system superior in performance to the conventional model designed primarily for heavy duty, proves after tests to be a highly sophisticated remotely controlled robot control system.

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    This case report demonstrates a case of 5-year-old non-syndromic Malay boy who passed the hearing screening test however he was confirmed has bilateral profound sensorineural hearing loss diagnosed at 3 months of age by brain stem evoked response (BSER). He has background history of severe neonatal jaundice and male siblings of hearing impairment. The antenatal and birth history was uneventful apart from maternal hypothyroidism. His other two elder brothers have bilateral sensorineural hearing loss and history of severe neonatal jaundice as well. The ear examinations, computed tomography scan and magnetic resonance imaging revealed normal findings. Right sided cochlear implantation was done at the age of 3 years old and he is still under audiology follow-up. Conclusion: Genetic studies are important to determine the cause of genetic mutation in susceptibility to hearing impairment that run in his family after severe neonatal jaundice. Those baby with risk of developing hearing loss required diagnostic hearing assessment. (author)

    To study the pharmacokinetic parameters of morphine and lidocaine after a single intravenous (i.v.) bolus in severe trauma patients. Clinical case study. Department of Anesthesiology and Intensive Care of a university hospital. Nine patients, ages 24 to 91 years (mean 54.4 yrs), admitted to the hospital with severe trauma (Injury Severity Score > 20) were included in the study. After initial evaluation and stabilization, a single i.v. dose of morphine 0.025 mg/kg and lidocaine 1.5 mg/kg was given separately, and blood samples were drawn for each drug serum concentration. Morphine pharmacokinetics was studied in eight patients, lidocaine pharmacokinetics in seven patients, and both drugs were studied in six patients. Morphine clearance 2.5 to 10 ml/kg/min (6 +/- 2.6, mean +/- SD) and volume of distribution 0.28 to 3.30 L/kg (1.4 +/- 1.0) were found to be lower than values described previously for healthy volunteers (33.5 +/- 9 ml/kg/min and 5.16 +/- 1.40 L/kg, respectively), and are similar to those described in trauma patients (5 +/- 2.9 ml/kg/min and 0.9 +/- 0.2 L/kg, respectively). In contrast, lidocaine clearance 4.5 to 9.4 ml/kg/min (6.7 +/- 1.7) and volume of distribution 0.39 to 1.20 L/kg (0.72 +/- 0.28) were similar to the value described in healthy volunteers (10 ml/kg/min and 1.32 L/kg, respectively). Changes in pharmacokinetics of drugs eliminated by the liver may occur in patients with severe trauma. The preserved lidocaine clearance indicates an almost normal hepatic blood flow and suggests that other mechanisms may be involved in the lower morphine clearance. The findings may have applications for the treatment of severe trauma patients and suggest that drug monitoring might be needed in some instances so as to avoid toxicity.

    Cervical epidural anesthesia has been used widely for surgery of upper limbs. Although cervical epidural anesthesia with local anesthetic of 2% lidocaine (plain) has demonstrated the safety in respiratory function in spite of unavoidable phrenic and intercostal palsies to certain extent, the replacement of local anesthetics with 2% lidocaine plus epinephrine has not been investigated yet. I conducted this study to look into the effect of 2% lidocaine plus epinephrine on respiratory function. I collected data from 50 patients with mean age of 24 +/- 3 yrs, mean weight of 65 +/- 10 kg, ASA status: I-II without preoperative pulmonary dysfunction undergoing orthropedic open-reduction with internal fixation because of fractures of upper limbs. Cervical epidural space (C7-T1) was approached by hanging-drop method, using a 17G Tuohy needle. A catheter was inserted craniad to a distance of 12 cm. Pulmonary function measurement and arterial blood gas data were obstained before, 20 min, 50 min and 105 min after injection of 12 mL 2% lidocaine with 1:200,000 epinephrine. The anesthesia levels were between C3-T3 and obtained 15 +/- 2 min after injection. Mean arterial blood gas analysis showed mild respiratory acidosis at 20 min (PaCO2: 48 +/- 3 mmHg) and 50 min (PaCO2: 44 +/- 2 mmHg). The measured values of inspiratory vital capacity (IVC), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), peak expiratory flow (PEF) when compaired with control values, were decreased about 18.0% and 12.1% of the control values at 20 min and 50 min respectively. The ratios of FEV1/VC, FEV1/FVC were still within normal limits (> 80%). The results were significantly compatible with the criteria of mild restrictive type of pulmonary function. Cervical epidural anesthesia with 2% lidocaine plus epinephrine could reduce lung volumes and capacities, resulting from partially paralytic intercostal muscles and diaphragm innervated respectively by thoracic

    Full Text Available Srinivas Nalamachu,1 Matthew Wieman,2 Leah Bednarek,2 Surya Chitra21International Clinical Research Institute, Overland Park, KS, 2Endo Pharmaceuticals Inc, Malvern, PA, USAPurpose: Lidocaine patch 5% is recommended as a first-line therapy for postherpetic neuralgia pain in neuropathic pain guidelines. Postherpetic neuralgia can occur anywhere on the body but often follows acute herpes zoster occurring in trigeminal and brachial plexus dermatomes. An analysis was conducted to determine whether the anatomic location of lidocaine patch 5% is associated with variations in effectiveness or tolerability in patients with postherpetic neuralgia.Methods: This was a post hoc analysis by anatomic site of patch placement (head [including neck], trunk [chest, abdomen, back, hips], and extremities [arm, leg] of a 4-week, multicenter, open-label study that enrolled patients with persistent pain following herpes zoster infection. Effectiveness was measured by Brief Pain Inventory (BPI average pain intensity (0 [no pain] to 10 [worst imaginable pain] and the BPI subscale for pain relief (0% [no relief] to 100% [complete relief]. Tolerability was assessed on the basis of patient-reported adverse events.Results: Of 332 enrolled patients (59.6% women [n = 198]; 92.5% white [n = 307]; mean [standard deviation] age, 71.2 [13.9] years, those (n = 203 who applied lidocaine patch 5% to a single anatomic site only and had baseline and postbaseline pain score data were analyzed (trunk, n = 130; head, n = 41; extremities, n = 32. The frequency of adverse events differed significantly by anatomic location, with significantly more adverse events reported with patch placement on the head versus the extremities (P = 0.006 or trunk (P = 0.02. BPI average pain improved significantly from baseline in each of the three anatomic areas (mean score decrease, 1.50–2.04; P ≤ 0.002, with no significant difference in effectiveness by patch location.Conclusion: Lidocaine 5% patch was

    Full Text Available Purpose. To report a case of bilateral Coats’ disease combined with retinopathy of prematurity (ROP. Case. Retinal vascularization was complete in the right eye, whereas zone III, stage 3 ROP and preplus disease were observed in the left eye at 43 weeks of postmenstrual age (PMA in a 31-week premature, 1200-g neonate. Intraretinal exudates developed and retinal hemorrhages increased in the left eye at 51 weeks of PMA. Diode laser photocoagulation (LP was applied to the left eye. Exudates involved the macula, and telangiectatic changes developed one month following LP. Additional LP was applied to the left eye combined with intravitreal bevacizumab (IVB injection at 55 weeks of PMA. Disease regressed one month after the additional therapy. At the 14-month examination of the baby, telangiectatic changes and intraretinal exudates were observed in the right eye. Diode LP was applied to the right eye combined with IVB injection. Exudates did not resolve completely, and cryotherapy was applied one month following LP. Retinal findings regressed three months following the cryotherapy. Conclusion. This is the first report of presumed bilateral Coats’ disease combined with ROP. If Coats’ disease could be diagnosed at early stages, it would be a disease associated with better prognosis.

    This study examines the preparation of sustained-release lidocaine polyelectrolyte complex using reactive melt extrusion. Eudragit L100-55 was selected as the ionic polymer. The influence of drug forms (freebase vs. hydrochloride salt) on lidocaine-Eudragit L100-55 interactions, physical stability, and dissolution properties of extrudates was investigated. It was confirmed by DSC, FT-IR and Raman spectroscopy that polyelectrolyte could only form via the acid-base reaction between Eudragit L100-55 and lidocaine freebase. Due to this ionic interaction, the lidocaine extrudate was physically more stable than the lidocaine hydrochloride extrudate during the storage under stressed condition. Drug release from lidocaine extrudate was a function of drug solubility, polymer solubility, drug-polymer interaction, and drug-induced microenvironment pH. At 30% drug loading, extrudate exhibited sustained release in aqueous media at pH 1.2 and 4.5. Due to the alkaline microenvironment pH induced by dissolved lidocaine, Eudragit L100-55 was solubilized and sustained-release was not achieved in water and aqueous media at pH 5.5. In comparison, lidocaine hydrochloride induced an acidic microenvironment. Drug release of lidocaine hydrochloride extrudate was similar at pH 1.2, 4.5, 5.5 and water with drug being released over 10 hours. The release of lidocaine hydrochloride from the extrudates in these media was primarily controlled by microenvironment pH. It is concluded that different forms of lidocaine resulted in different drug-polymer interactions and distinctive physicochemical properties of extrudates. Copyright © 2018.

    to evaluate the effects of blocking the regulation of vascular tone on the ischemia and reperfusion syndrome in rats through the use of lidocaine in the postconditioning technique. we randomized 35 rats into seven groups of five animals: Group 1- Control; Group 2- Ischemia and Reperfusion; Group 3- Ischemia, Reperfusion and Saline; Group 4- Ischemic Postconditioning; Group 5- Ischemic Postconditioning and Saline; Group 6- Lidocaine; Group 7- Ischemic Postconditioning and Lidocaine. Except for the control group, all the others were submitted to renal ischemia for 30 minutes. In postconditioning groups, we performed ischemia and reperfusion cycles of five minutes each, applied right after the main ischemia. In saline and lidocaine groups, we instilled the substances at a rate of two drops per minute. To compare the groups, we measured serum levels of urea and creatinine and also held renal histopathology. The postconditioning and postconditioning + lidocaine groups showed a decrease in urea and creatinine values. The lidocaine group showed only a reduction in creatinine values. In histopathology, only the groups submitted to ischemic postconditioning had decreased degree of tubular necrosis. Lidocaine did not block the effects of postconditioning on renal ischemia reperfusion syndrome, and conferred better glomerular protection when applied in conjunction with ischemic postconditioning. avaliar os efeitos do bloqueio da regulação do tônus vascular por meio do uso da lidocaína na técnica de pós-condicionamento isquêmico na síndrome de isquemia e reperfusão renal em ratos. trinta e cinco ratos foram randomizados em sete grupos de cinco animais: Grupo 1- Controle; Grupo 2- Isquemia e Reperfusão; Grupo 3- Isquemia, Reperfusão e Solução Salina; Grupo 4- Pós-condicionamento Isquêmico; Grupo 5- Pós-condicionamento Isquêmico e Solução Salina; Grupo 6- Lidocaína; Grupo 7- Pós-condicionamento Isquêmico e lidocaína.

    The purpose of this study was to evaluate the diagnostic value of conventional magnetic resonance imaging (MRI), proton magnetic resonance spectroscopy ( 1 H-MRS), and diffusion-weighted imaging (DWI) for neonatal bilirubin encephalopathy. We collected conventional MRI in 24 neonates with neonatal bilirubin encephalopathy. We performed 1 H-MRS and DWI sequences to nine of the 24 patients and seven age-matched healthy control subjects. Multiple-voxel 1 H-MRS data were acquired using PRESS pulse sequence with TE=135 ms and TR=1500 ms. The spectroscopic regions of interest were the bilateral basal ganglia and thalamus with a 1.0 mL spatial resolution. The data from DWI were collected by using a single shot-spin echo-echo planar imaging sequence with TR/TE: 2900/98, and imaging regions were also focused on the bilateral basal ganglia and thalamus. Nineteen of the 24 patients had abnormal T 1 -weighted image hyperintensity in the globus pallidus, but these lesions appeared as normal T 2 -weighted image intensity in the same region. Ten of the 24 patients had T 1 -weighted image high signal intensity in the subthalamic nucleus and appeared as normal intensity in the region for the T 2 -weighted images. The peak area ratios of NAA/Cho and NAA/Cr were significantly decreased (t-test, P 1 H-MRS are important complementary tools in the diagnosis of neonatal bilirubin encephalopathy. The study provides important information for applying these MR modalities to evaluate neonates with bilirubin encephalopathy. (orig.)

  15. Muscle-type nicotinic receptor modulation by 2,6-dimethylaniline, a molecule resembling the hydrophobic moiety of lidocaine

    Full Text Available To identify the molecular determinants responsible for lidocaine blockade of muscle-type nAChRs, we have studied the effects on this receptor of 2,6-dimethylaniline (DMA, which resembles lidocaine’s hydrophobic moiety. Torpedo marmorata nAChRs were microtransplanted to Xenopus oocytes and currents elicited by ACh (IACh, either alone or co-applied with DMA, were recorded. DMA reversibly blocked IACh and, similarly to lidocaine, exerted a closed-channel blockade, as evidenced by the enhancement of IACh blockade when DMA was pre-applied before its co-application with ACh, and hastened IACh decay. However, there were marked differences among its mechanisms of nAChR inhibition and those mediated by either the entire lidocaine molecule or diethylamine (DEA, a small amine resembling lidocaine’s hydrophilic moiety. Thereby, the IC50 for DMA, estimated from the dose-inhibition curve, was in the millimolar range, which is one order of magnitude higher than that for either DEA or lidocaine. Besides, nAChR blockade by DMA was voltage-independent in contrast to the increase of IACh inhibition at negative potentials caused by the more polar lidocaine or DEA molecules. Accordingly, virtual docking assays of DMA on nAChRs showed that this molecule binds predominantly at intersubunit crevices of the transmembrane-spanning domain, but also at the extracellular domain. Furthermore, DMA interacted with residues inside the channel pore, although only in the open-channel conformation. Interestingly, co-application of ACh with DEA and DMA, at their IC50s, had additive inhibitory effects on IACh and the extent of blockade was similar to that predicted by the allotopic model of interaction, suggesting that DEA and DMA bind to nAChRs at different loci. These results indicate that DMA mainly mimics the low potency and non-competitive actions of lidocaine on nAChRs, as opposed to the high potency and voltage-dependent block by lidocaine, which is emulated by the

    Postoperative vomiting (POV) is a frequent complication of tonsillectomy in children. In adult patients undergoing abdominal surgeries, the use of intravenous lidocaine infusion can prevent POV. To evaluate the anti-emetic effect of an intravenous lidocaine infusion used as an adjuvant to general anaesthesia, in children undergoing elective ear, nose and throat surgery. Double-blind, randomised, controlled study. Hospital-based, single-centre study in Chile. ASA I-II children, aged 2 to 12 years, scheduled for elective tonsillectomy. We standardised the induction and maintenance of anaesthesia. Patients were randomly allocated to lidocaine (1.5 mg kg intravenous lidocaine over 5 min followed by 2 mg kg h) or 0.9% saline (at the same rate and volume). Infusions were continued until the end of the surgery. Presence of at least one episode of vomiting, retching or both in the first 24 h postoperatively (POV). Plasma concentrations of lidocaine and postoperative pain. Ninety-two children were enrolled. Primary outcome data were available for 91. In the Lidocaine group, 28 of 46 patients (60.8%) experienced POV, compared with 37 of 45 patients (82.2%) in the Saline group [difference in proportions 21.3% (95% confidence interval (CI) 2.8 to 38.8), P = 0.024]. The intention-to-treat analysis showed that when we assumed that the patient in the Saline group lost to follow-up did not have POV, the difference in proportions decreased to 19.6% (95% CI, 0.9 to 37.2), with an unadjusted odds ratio of 0.38 (95% CI, 0.15 to 0.97, P = 0.044). The odds of having POV were 62% less likely in those patients receiving lidocaine compared with patients in the Saline group. The mean lidocaine plasma concentration was 3.91 μg ml (range: 0.87 to 4.88). Using an intravenous lidocaine infusion as an adjuvant to general anaesthesia decreased POV in children undergoing elective tonsillectomy. ClinicalTrials.gov Identifier: NCT01986309.

    Background: To compare 4% articaine and 2% lidocaine local anesthetics in achieving pulpal anesthesia of the lower first permanent molar teeth objectively, and to assess and compare lip and lingual mucosa numbness subjectively. Materials and Methods: All subjects received 1.7 ml of any one anesthetic in the mucobuccal fold adjacent to mandibular first molar teeth; the same individuals received the second infiltration at least 1 week after the first. Later, comparisons for pulpal anesthesia, lip and lingual mucosa numbness between these two anesthetics solutions were made. Results: Articaine showed significant results with P = 0.006 in achieving pulpal anesthesia objectively, when compared with lidocaine. Articaine also showed very high significant results subjectively with P = 0.0006 in achieving lip numbness, when compared with lidocaine. But the results in achieving lingual mucosa numbness with articaine subjectively was not significant with P = 0.01, when compared with lidocaine. Conclusion: Endodontic and operative treatments are one of the most common oral non-surgical procedures done under local anesthesia. The diversity of anesthetic substances currently available on the market requires dental professionals to assess the drug both by its pharmacokinetic and also by its clinical characteristics during dental treatments. Our study used 4% articaine, which is available in the market, for comparison with 2% lidocaine. Further studies are required to use an equal concentration of solutions to achieve more accurate results. PMID:26759799

    Iontophoresis (IOP) is a noninvasive method of delivering medication transcutaneously through the skin. The electrodes used in this method should tightly fit to rough and irregular surfaces and be biologically safe, easy to handle and prepare, and cost-effective. To satisfy these requirements, calcium alginate gel can be a candidate electrode for IOP. Using calcium alginate gel electrodes, we examined whether lidocaine can be effectively transported across an excised rat skin by squarewave alternating current (AC) application. A squarewave AC with either a 70% or 80% duty cycle was continuously applied to 0.5% calcium alginate gel electrodes containing 10% lidocaine at 10 V and 1 kHz for 60 min. Lidocaine concentration was measured using a spectrophotometer and the temperature of the gel was determined. The lidocaine concentrations for AC-IOP at the 70% and 80% duty cycles were significantly higher than that without AC-IOP. Furthermore, the group with the 80% duty cycle showed higher lidocaine concentrations than the group with the 70% duty cycle. The temperatures of all the groups were lower than 28 °C throughout the procedure. In conclusion, the calcium alginate gel can be used as a possible matrix for IOP electrodes.

    Full Text Available Effects of ketamine and lidocaine on electroencephalographic (EEG changes were evaluated in minimally anaesthetized dogs, subjected to electric stimulus. Six dogs were subjected to six treatments in a crossover design with a washout period of one week. Dogs were subjected to intravenous boluses of lidocaine 2 mg/kg, ketamine 3 mg/kg, meloxicam 0.2 mg/kg, morphine 0.2 mg/kg and loading doses of lidocaine 2 mg/kg followed by continuous rate infusion (CRI of 50 and 100 mcg/kg/min, and ketamine 3 mg/kg followed by CRI of 10 and 50 mcg/kg/min. Electroencephalogram was recorded during electrical stimulation prior to any drug treatment (before treatment and during electrical stimulation following treatment with the drugs (after treatment under anaesthesia. Anaesthesia was induced with propofol and maintained with halothane at a stable concentration between 0.85 and 0.95%. Pretreatment median frequency was evidently increased (P<0.05 for all treatment groups. Lidocaine, ketamine, and morphine depressed the median frequency resulting from the posttreatment stimulation. The depression of median frequency suggested evident antinociceptive effects of these treatments in dogs. It is therefore concluded that lidocaine and ketamine can be used in the analgesic protocol for the postoperative pain management in dogs.

    Using peripheral nerve block compared to general anesthesia has gained more popularity due to reduced postoperative pain, less need for post-surgery analgesic drugs, reduced incidence of nausea, shortness of PACU time, and increased patient satisfaction. The aim of this study was to compare the effect of ketamine and dexamethasone as additives to lidocaine on duration and onset of axillary block action. In this clinical trial, all patients who referred to Hazrat-e-Fatemeh hospital for forearm and hand soft tissue surgery with informed consent were randomly divided into three groups in order to examine the onset and duration of axillary block: lidocaine + ketamine, lidocaine + dexamethasone in axillary block, and lidocaine alone (control). Then, the onset and duration of sensory and motor blocks were measured and recorded every three minutes and after the surgery. Quantitative and qualitative variables were analyzed using ANOVA or Kruskal-Wallis test and Chi-square or Fisher exact test in SPSS v.22. Duration of sensory and motor block axillary was significantly higher in lidocaine + dexamethasone group than in lidocaine + ketamine group (P block axillary between the three groups (P > 0.05). According to the results of our study, we can conclude that adding dexamethasone or ketamine to lidocaine could improve duration of sensory and motor axillary block in patients undergoing forearm and hand soft tissue surgery. However, dexamethasone had the highest effect on duration of block axillary. We proved that dexamethasone or ketamine added to lidocaine had no effect on the onset of block axillary.

    One-per-mil tumescent solution, which contains 0.2% lidocaine with 1:1,000,000 epinephrine, has been reported to be clinically effective for hand surgery under local anesthesia. However, it was lacking in its basic pharmacokinetics profile in regard to the onset of action (OOA) and duration of action (DOA). A randomized, double-blind study was conducted on 12 volunteers who met the inclusion criteria from October to November 2014. All volunteers had their right and left ring finger pulps injected with either one-per-mil solution or 2% lidocaine. Semmes-Weinstein and two-point discrimination tests were used to test sensation. Visual analogue scale was recorded at the time when the finger lost its sensation and when it regained normal sensation to measure the OOA and DOA. The data were then analyzed with a paired t-test and a Wilcoxon signed-rank test. The OOA and DOA of 2% plain lidocaine were 1 minute and 99.67 minutes, respectively. Meanwhile, 0.2% lidocaine in a one-per-mil tumescent solution showed an OOA of 5 minutes and a DOA of 186.83 minutes. The OOA of 0.2% lidocaine in a one-per-mil tumescent solution is statistically shorter than 2% plain lidocaine (P=0.04); while its DOA is statistically longer than 2% plain lidocaine (Pmil tumescent solution is statistically and clinically superior to 2% plain lidocaine in achieving longer duration of local anesthesia.

    Full Text Available Brachial plexus is an important group of spinal nerve plexus that supplies the muscles of the upper limb via the ventral rami of the Cervical 5 - Thoracic 1 fibers of the spinal nerves. It is not uncommon to notice the variations during cadaveric dissections in many regions of the body, at different levels, such as, roots, trunks, division, cords, communications, and branches as reported in the literature. Although the nerve supply of the body musculature takes place in the fetal life itself, its course, branching pattern, innervations, and communication can show variable patterns as the fetal development progresses. One such anomaly was noticed during our routine cadaveric dissection in the Department of Anatomy, Jawaharlal Nehru Medical College, Belgaum, showing bilateral absence of the musculocutaneous nerve, which obviously drew the attention of the students of medicine, physiotherapy, and learning clinicians as well.

    Full Text Available Supernumerary teeth are more common in the permanent than in primary dentition. In the primary dentition, the anomaly is most frequently observed in the maxillary lateral incisor region, followed by the maxillary midline where they are termed as mesiodens. Supernumerary teeth in the primary canine region are rare. This paper describes a rare case of nonsyndromic supernumerary primary maxillary canine distributed bilaterally in a 4-year-old boy. Both the supernumeraries resembled size and shape of normal primary canine. The right supplemental canine is high labially placed, whereas the left one is seen normally aligned in the dental arch distal to lateral incisor. One of the most significant sequelae of primary supernumerary teeth is their duplication in the permanent series. Radiographic examination of supernumerary primary canine did not indicate any such anomaly in the permanent dentition. The patient was kept under observation.

    Full Text Available The pain phenomena as a disabling state but normal fact in human have been noticed to alarm and concern to the tissue injury and damage. Pain management is one the most worldwide clinical challenges in general population that is associated with considerable health care expenses, decreased productive time and impression on the quality of life. Numerous studies have been done to identify its pathophysiology and effective therapeutic agents. Attention to pain etiology, the relationship of inflammatory pathways, the molecular mechanisms and involved transmitters have given insights to novel approaches with more effective pain relief agents. In addition to over the counter analgesic and prescription medicine (NSAIDs, opioids, COX-2 inhibitors, there is no consensus about the analgesic role of herbal medicines. Cochrane library reviewed the place of herbal medicine in low back pain. They showed although the RCTs were not large trials and well-designed but herbal medicine could reduce pain more than placebo in short term without significant side effects (1.Lidocaine as local/regional anesthetic agent has been introduced to reduce acute postoperative pain, the chronic pain conditions, myofascial pain, refractory neuropathic pain and neuralgia. In cancer pain patients with refractory to opioid agents, lidocaine infusion could achieve adequate analgesic state (2.

There is strong evidence to decrease pain scores in abdominal surgeries (both open and laparoscopy. In prostate, breast, thoracic and spine operations, the evidence is moderate with small benefit. In cardiac surgery, lidocaine infusion would decrease postoperative cognitive disorder with no analgesic effect (3. Lidocaine acts predominantly through blocking sodium channels.

    Full Text Available Introduction: Neonatal nasal airway obstruction induces various degrees of respiratory distress. The management of this disease, including surgical repair, will depend on the severity and location of the obstruction. We describe here a case of congenital nasal nostril stenosis that required surgical repair for stenting of both nares after coanal atresia repair.   Case Report: A 2 days old female newborn referred to neonatal department of Tabriz Children’s Hospital affiliated to the University of Medical Sciences of Tabriz, Iran on the 3rd of December, 2011 immediately after birth with respiratory distress due to bilateral coanal atresia and nasal hypoplasia with very small nostrils. CT scan showed normal brain and bilateral choanal atresia with normal size Pyriform apertures.   Conclusion: Nasal obstruction can lead to airway compromise and respiratory distress. Congenital bony nasal deformities are being recognized as an important cause of newborn airway obstruction. Nasal hypoplasia is seen in many craniofacial syndromes. Although our patient had hypoplastic nostrils with respiratory distress due to bilateral coanal atresia, correction of hypoplastic nostrils was necessary for completing the operation of choanal atresia.

    Ultrasonography (US) is as an important tool for differentiation of obstructive and non-obstructive causes of jaundice in infants and children. Beyond two weeks of age, extrahepatic biliary atresia and neonatal hepatitis are the two most common causes of persistent neonatal jaundice: differentiation of extrahepatic biliary atresia, which requires early surgical intervention, is very important. Meticulous analysis should focus on size and configuration of the gallbladder and anatomical changes of the portahepatis. In order to narrow the differential diagnosis, combined approaches using hepatic scintigraphy, MR cholangiography, and, at times, percutaneous liver biopsy are necessary. US is useful for demonstrating choledochal cyst, bile plug syndrome, and spontaneous perforation of the extrahepatic bile duct

    Neonatal lupus erythematosus (NLE) is an uncommon disease of the neonate. It is believed to be caused by the transplacental passage of maternal autoantibodies to the ribonucleoproteins (Ro\\/SSA, La\\/SSB or rarely U RNP) as these are almost invariably present in NLE sera. The most common clinical manifestations include cutaneous lupus lesions and congenital complete heart block. Hepatobiliary and haematologic abnormalities are reported less frequently. We describe a patient with cutaneous NLE to illustrate and raise awareness of the characteristic annular eruption of this condition. We also emphasize the need for thorough investigation for concomitant organ involvement and for maternal education regarding risk in future pregnancies.

    We have examined the effect of systemic administration of ketamine and lidocaine on brush-evoked (dynamic) pain and punctate-evoked (static) hyperalgesia induced by capsaicin. In a randomized, double-blind, placebo-controlled, crossover study, we studied 12 volunteers in three experiments....... Capsaicin 100 micrograms was injected intradermally on the volar forearm followed by an i.v. infusion of ketamine (bolus 0.1 mg kg-1 over 10 min followed by infusion of 7 micrograms kg-1 min-1), lidocaine 5 mg kg-1 or saline for 50 min. Infusion started 15 min after injection of capsaicin. The following...... were measured: spontaneous pain, pain evoked by punctate and brush stimuli (VAS), and areas of brush-evoked and punctate-evoked hyperalgesia. Ketamine reduced both the area of brush-evoked and punctate-evoked hyperalgesia significantly and it tended to reduce brush-evoked pain. Lidocaine reduced...

    This prospective, randomized, placebo-controlled study evaluated the effects of dexketoprofen as an adjunct to lidocaine in intravenous regional anaesthesia (IVRA) or as a supplemental intravenous (i.v.) analgesic. Patients scheduled for elective hand or forearm soft-tissue surgery were randomly divided into three groups. All 45 patients received 0.5% lidocaine as IVRA. Dexketoprofen was given either i.v. or added into the IVRA solution and the control group received an equal volume of saline both i.v. and as part of the IVRA. The times of sensory and motor block onset, recovery time and postoperative analgesic consumption were recorded. Compared with controls, the addition of dexketoprofen to the IVRA solution resulted in more rapid onset of sensory and motor block, longer recovery time, decreased intra- and postoperative pain scores and decreased paracetamol use. It is concluded that coadministration of dexketoprofen with lidocaine in IVRA improves anaesthetic block and decreases postoperative analgesic requirements.

    To determine the effects of burdizzo castration alone or in combination with ketoprofen (K), local anesthesia (LA), or caudal epidural anesthesia (EPI) on plasma cortisol, acute-phase proteins, interferon-gamma production, growth, and behavior of beef cattle, 50 Holstein x Friesian bulls (13 mo old, 307 +/- 5.3 kg) were assigned to (n = 10/treatment): 1) control (handled; C); 2) burdizzo castration (B); 3) B following K (3 mg/ kg of BW i.v.; BK); 4) B following LA (8 mL into each testis and 3 mL s.c. along the line where the jaws of the burdizzo were applied with 2% lidocaine HCl; BLA); and 5) B following EPI (0.05 mg/kg of BW of xylazine HCl and 0.4 mg/kg of BW of lidocaine HCl as caudal epidural; BEPI). The area under the cortisol curve against time was lower (P castration groups than in C. On d 7, haptoglobin and fibrinogen concentrations remained higher (P castration increased plasma cortisol and acute-phase proteins, and suppressed immune function and growth rates. Local anesthesia prolonged the increase in acute-phase proteins. Ketoprofen was more effective than LA or EPI in decreasing cortisol and partially reversed the reduction in ADG following castration. The use of K or EPI was more effective than LA in decreasing pain-associated behavioral responses observed during the first 6 h after treatment. Systemic analgesia with ketoprofen, a non-steroidal antiinflammatory drug, was more effective in reducing inflammatory responses associated with castration than LA or EPI.

    Endothelial cells play a key role in ischemia reperfusion injury. We investigated the effects of lidocaine on activated human umbilical vein endothelial cell (HUVEC) interleukin (IL)-1beta, IL-6, and IL-8 concentrations and intercellular adhesion molecule-1 (ICAM-1) expression. HUVECs were pretreated with different concentrations of lidocaine (0 to 0.5 mg\\/mL) for 60 min, thereafter tumor necrosis factor-alpha was added at a concentration of 2.5 ng\\/mL and the cells incubated for 4 h. Supernatants were harvested, and cytokine concentrations were analyzed by enzyme-linked immunosorbent assay. Endothelial ICAM-1 expression was analyzed by using flow cytometry. Differences were assessed using analysis of variance and post hoc unpaired Student\\'s t-test where appropriate. Lidocaine (0.5 mg\\/mL) decreased IL-1beta (1.89 +\\/- 0.11 versus 4.16 +\\/- 1.27 pg\\/mL; P = 0.009), IL-6 (65.5 +\\/- 5.14 versus 162 +\\/- 11.5 pg\\/mL; P < 0.001), and IL-8 (3869 +\\/- 785 versus 14,961 +\\/- 406 pg\\/mL; P < 0.001) concentrations compared with the control. IL-1beta, IL-6, and IL-8 concentrations in HUVECs treated with clinically relevant plasma concentrations of lidocaine (0.005 mg\\/mL) were similar to control. ICAM-1 expression on lidocaine-treated (0.05 mg\\/mL) HUVECs was less than on controls (198 +\\/- 52.7 versus 298 +\\/- 50.3; Mean Channel Fluorescence; P < 0.001). Activated endothelial IL-1beta, IL-6, and IL-8 concentrations and ICAM-1 expression are attenuated only by lidocaine at concentrations larger than clinically relevant concentrations.

    The aim of this study was to evaluate and compare the effects of spinal anesthesia with lidocaine and with bupivacaine on urinary bladder function in healthy men who were scheduled for minor orthopaedic surgical procedures. Twenty men were randomly allocated to receive either bupivacaine or lidocaine. Before spinal anesthesia, filling cystometry was performed with the patient in the supine position and a pressure flow study was done with the patient in the standing position. After operation, cystometric measurements were continued until the patient could void urine spontaneously. The levels of analgesia and of motor blockade were recorded. The urge to void disappeared immediately after injection of the local anesthetics. There was no difference in the duration of lower extremity motor blockade between bupivacaine and lidocaine. Detrusor blockade lasted significantly longer in the bupivacaine group (means +/- SD, 460 +/- 60 min) than in the lidocaine group (235 +/- 30 min). Total fluid intake and urine volume accumulated during the detrusor blockade were significantly higher in the bupivacaine group than in the lidocaine group. In the bupivacaine group, the total volume of accumulated urine (875 +/- 385 ml) was also significantly higher than cystometric bladder capacity (505 +/- 120 ml) with the risk of over distension of the bladder. Spontaneous voiding of urine did not occur until segmental sensory analgesia had regressed to the third sacral segment. Spinal anesthesia with lidocaine and with bupivacaine causes a clinically significant disturbance of bladder function due to interruption of the micturition reflex. The urge to void disappears quickly and bladder function remains impaired until the block has regressed to the third sacral segment in all patients. With long-acting local anesthetics, the volume of accumulated urine may exceed the cystometric bladder capacity. With respect to recovery of urinary bladder function, the use of short-acting local anesthetics

    Achieving profound pulpal anesthesia can be difficult in patients with symptomatic irreversible pulpitis. This study provides a systematic review and meta-analysis to address the population, intervention, comparison, outcome (PICO) question: in adults with symptomatic irreversible pulpitis who are undergoing endodontic treatment, what is the comparative efficacy of articaine compared with lidocaine in reducing pain and incidence of adverse events? A protocol was prepared and registered on PROSPERO. Electronic searches were conducted in MEDLINE, Scopus, Cochrane Library, and ClinicalTrials.gov by using strict inclusion and exclusion criteria. Two independent reviewers assessed eligibility for inclusion and quality. Weighted anesthesia success rates and 95% confidence intervals (CIs) were estimated and compared by using a random-effects model. Two hundred seventy-five studies were initially identified from the search; 10 double-blind, randomized clinical trials met the inclusion criteria. For combined studies, articaine was more likely than lidocaine to achieve successful anesthesia (odds ratio [OR], 2.21; 95% CI, 1.41-3.47; P = .0006; I(2) = 40%). Maxillary infiltration subgroup analysis showed no significant difference between articaine and lidocaine (OR, 3.99; 95% CI, 0.50-31.62; P = .19; I(2) = 59%). For combined mandibular anesthesia studies articaine was superior to lidocaine (OR, 2.20; 95% CI, 1.40-3.44; P = .0006; I(2) = 30%), with further subgroup analysis showing no difference for mandibular block anesthesia (OR, 1.44; 95% CI, 0.87-2.38; P = .16; I(2) = 0%). When used for supplemental infiltration after successful mandibular block anesthesia, articaine was significantly more effective than lidocaine (OR, 3.55; 95% CI, 1.97-6.39; P pulpitis. There is a significant advantage to using articaine over lidocaine for supplementary infiltration after mandibular block anesthesia but no advantage when used for mandibular block anesthesia alone or for maxillary

    To compare the effects of intrauterine lidocaine, intrauterine lidocaine plus rectal diclofenac, and a placebo on analgesia and to determine the satisfaction of patients and surgeons in cases of endometrial biopsy. The double-blind, randomised, placebo-controlled study was conducted in the Department of Obstetrics and Gynaecology of the Ondokuz Mayis University, Samsun,Turkey, from April 2013 to January 2014, and comprised patients scheduled for in-office endometrial biopsy.They were divided into three groups: Group P, 5ml of 0.9% saline intrauterine; Group L, 5ml of 2% lidocaine intrauterine; and Group LD, 5ml of 2% lidocaine intrauterine ± 10min before the procedure plus 50mg of rectal diclofenac sodium. Haemodynamic changes and visual analogue scale scores were recorded during the preoperative period, when the cervix was grasped with a tenaculum, immediately after intrauterine instillation, during uterine curettage and at postoperative 10 min. The patient and the surgeon were questioned about their satisfaction 15 min after the procedure. SPSS 21 was used for statistical analysis. The 90 patients in the study were divided into three equal groups of 30(33.33%) each. There were no statistically significant inter-group differences in age, bodyweight, parity, number of postmenopausal patients, haemodynamic parameters and American Society of Anesthesiologists scores (p>0.05 in all categories). In Group P, the visual analogue scale score estimated when the cervix was grasped with the tenaculum was lower when compared with Group L and Group LD (p=0.029 and p=0.007, respectively). At other measurement time points, the scores did not differ between the groups. The groups did not differ with respect to patient and surgeon satisfaction and complication rates (p>0.05). Intrauterine lidocaine or intrauterine lidocaine plus rectal diclofenac application had no effect on visual analogue scale scores, patient satisfaction and vasovagal reaction.

    Nikethamide and lidocaine are often requested to be quantified simultaneously in forensic toxicological analysis. A simple reversed-phase high performance liquid chromatography (RP-HPLC) method has been developed for their simultaneous determination in human blood and cerebrospinal fluid. The method involves simple protein precipitation sample treatment followed by quantification of analytes using HPLC at 263 nm. Analytes were separated on a 5 microm Zorbax Dikema C18 column (150 mm x 4.60 mm, i.d.) with a mobile phase of 22:78 (v/v) mixture of methanol and a diethylamine-acetic acid buffer, pH 4.0. The mean recoveries were between 69.8 and 94.4% for nikethamide and between 78.9 and 97.2% for lidocaine. Limits of detection (LODs) for nikethamide and lidocaine were 0.008 and 0.16 microg/ml in plasma and 0.007 and 0.14 microg/ml in cerebrospinal fluid, respectively. The mean intra-assay and inter-assay coefficients of variation (CVs) for both analytes were less than 9.2 and 10.8%, respectively. The developed method was applied to blood sample analyses in eight forensic cases, where blood concentrations of lidocaine ranged from 0.68 to 34.4 microg/ml and nikethamide ranged from 1.25 to 106.8 microg/ml. In six cases cerebrospinal fluid analysis was requested. The values ranged from 20.3 to 185.6 microg/ml of lidocaine and 8.0 to 72.4 microg/ml of nikethamide. The method is simple and sensitive enough to be used in toxicological analysis for simultaneous determination of nikethamide and lidocaine in blood and cerebrospinal fluid.

    To compare retrospective use of oral sucrose (SUC) vs oral sucrose plus lidocaine ring block (SUC + RB) in the management of pain during neonatal circumcision. A retrospective review of medical records of newborns circumcised using the "Neonatal Infant Pain Scale" was done. With regard to pain, the SUC group had a significantly greater percentage of those with pain than the SUC + RB group at 1 minute (77.7% vs 69.4%; P = .01) and 5 minutes (65.7% vs 55.7%; P = .004). There was no significant pain difference at 30 minutes. In the multivariate logistic regression analyses, those in the SUC group had significantly greater odds for pain at 1 minute than those in the SUC + RB group (odds ratio 1.45, 95% confidence interval 1.04-2.02; P = .03). No significant difference was noted at 5 minutes. Each of the SUC and SUC + RB groups had significant decreases in pain percentages at 5 minutes and 30 minutes (P analgesia. In addition, for post-term neonates, we recommend greater focus on pain levels, including considering higher dosages of pain medications. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background: Local anesthetics (LAs are generally considered as safe, but cytotoxicity has been reported for several local anesthetics used in humans, which is not well investigated. In the present study, the cytotoxicity of lidocaine, ropivacaine and the combination of lidocaine and ropivacaine were evaluated on human melanoma cell lines. Melphalan, a nitrogen mustard alkylating agent, was used as a control agent for comparison of cytotoxic activity. Methods: Melanoma cell lines, A375 and Hs294T, were exposed to 1 h to different concentrations of above agents. Cell-viability after exposure was determined by flow cytometry. Results: Investigated LAs showed detrimental cytotoxicity on studied melanoma cell lines in time- (p < 0.001, concentration- (p < 0.001, and agent dependant. In both A375 and Hs294T cell lines, minimum cell viability rates were found after 72 h of exposure to these agents. Lidocaine 2% caused a reduction of vital cells to 10% ± 2% and 14% ± 2% in A375 and Hs294T, respectively after 72 h of exposure. Ropivacaine 0.75% after 72 h reduced viable cells to 15% ± 3% and 25% ± 3% in A375 and Hs294T, respectively. Minimum cell viability after 72 h exposure to the combination was 10% ± 2% and 18% ± 2% in A375 and Hs294T, respectively. Minimum cell viability after 72 h exposure to melphalan was 8% ± 1% and 12% ± 2%, in A375 and Hs294T, respectively. Conclusion: LAs have cytotoxic activity on human melanoma cell lines in a time-, concentration- and agent-dependant manner. Apoptosis in the cell lines was mediated through activity of caspases-3 and caspases-8.

    2017-01-01

    Background: Transrectal ultrasound (TRUS) technique for getting prostatic tissue for histopathology is now the standard procedure for malignant lesions of the prostate and imperative diagnostic investigation of patients with clinical specks of prostatic neoplasia. During TRUS guided biopsy, pain control has been important issue therefore, highly potent analgesia before this procedure should be considered on high priority according to current census. Therefore, we compared intramuscular diclofenac injection with sensory blockade of injection lidocaine to abolish pain undergoing prostatic biopsy with TRUS technique. Methods: Total 200 patients were selected for this study having raised PSA values and suspicious nodule on Digital Rectal Examination. These patients were segregated into two groups by randomization. Group Ar eceived intramuscular diclofenac and group Bw ere infiltrated with lidocaine injection for sensory blockade. Results: Patients in group A was having mean age of 64.5±5.8 years while for group B patients was 65.6±4.9 years (p=0.16). Both groups have statistically insignificant difference in their mean PSA values (p=0.24) and mean prostatic volume (p=0.22). The mean pain scores on visual analogue scale in groups A was 3.5±0.8 and in group B it was 2.4±0.8 (p<0.001). 60% group A patients reported with mild or no pain compared to 90% in group B. (p<0.001). Conclusion: Local blockade with lidocaine injection has better pain control as compared to patients experienced pain with intramuscular diclofenac used for prostatic biopsy through TRUS technique.

    Aim: To present the results of a prospective, randomized, single-centre study investigating local anaesthesia before percutaneous common femoral artery (CFA) puncture and catheterization with the use of ultrasound-guided injection of lidocaine versus standard infiltration by manual palpation. Materials and methods: Patients scheduled to undergo diagnostic or therapeutic transfemoral catheter-based procedures gave informed consent and were randomized in two groups. In the first arm local anaesthesia with lidocaine hydrochloride 1% was performed under ultrasound guidance (group U/S), while in the second arm the standard method of manual artery palpation was applied (group M). In both groups, subsequent CFA catheterization was achieved under ultrasound guidance. The primary study endpoint was peri-procedural pain level evaluated with a visual-analogue scale (VAS score 0-10). Results: Between January 2009 and 2010, 200 patients (161 men, mean age 63 ± 12 years) were equally assigned to each group without any significant differences in baseline demographics. Patients in group U/S experienced significantly less pain during CFA catheterization in comparison with group M with a difference of three points in mean VAS score reported (1.6 ± 1.6 versus 4.6 ± 1.9, p < 0.0001). In addition, significantly less volume of lidocaine was used in group U/S compared to group M (16 ± 2.7 versus 19 ± 0.8 ml, p < 0.001).Total vascular access time was similar in both groups (4.4 ± 1.3 versus 4.5 ± 1.3 min). Overall complications included two small groin haematomas in each group. Conclusion: Ultrasound-guided local anaesthesia of the CFA prior to percutaneous transcatheter procedures is safe and achieves superior levels of analgesia with minimal patient pain and discomfort compared to the standard method of manual palpation.

Materials and Methods: This randomized clinical trial was conducted on 60 patients with American Society of Anesthesiologists Grades I and II, who were candidates for lower abdominal surgery in supine or lithotomy positions. Patients were randomly divided into early ambulation group (Group A who were asked to start walking as soon as the anesthesia was diminished or to the late ambulation group (Group B who walked after at least 12 h bedridden. Participants were contacted 2 days after spinal anesthesia to assess any type of pain at surgical or anesthesia injection site, muscle weakness, fatigue, vertigo, nausea, vomiting, headache, and difficult urination or defecation. Results: Four subjects (13.3% in Group A and two patients (6.7% in Group B had pain at anesthesia injection site (P = 0.019. Fourteen patients in Group A (46.7% and six patients in Group B (20% had post-dural puncture headache (P = 0.014. Participants in Group B reported difficult urination more than Group A (P = 0.002. there were not statistically significant differences between two groups regarding frequency of fatigue, muscle weakness, vertigo, nausea, vomiting, difficult defecation, paresthesia, and the mean of visual analogue scale at the surgical site. Conclusion: Early ambulation after spinal anesthesia with lidocaine did not increase the risk of neurologic complication.

    The aim of this study was to determine whether infiltration of local anesthetics with adrenaline improved septoplasty procedure when compared to normal saline. Eight-two patients undergoing septoplasty were randomized into two groups. In group 1, septal mucoperichondrium was infiltrated with lidocaine with adrenaline, and normal saline was used in group 2. Presence of intra-operative septal mucosal injuries, the amount of bleeding, arterial blood pressure, operation time as well as the quality of the surgical field and the convenience of finding the correct surgical plane as determined by the surgeon using a 5-point scale were compared between two groups. There were no significant differences for the amount of blood loss, mean arterial pressure, operation time, or scores for convenience of finding the correct surgical plane between the two groups. There was no significant difference for intra-operative simple (P = 0.631) and total (simple+severe) (P = 0.649) septal mucoperichondrial injuries between groups 1 and 2, either. However, severe mucoperichondrial injury rate was higher in the patients infiltrated with lidocaine and adrenaline (P = 0.026), and the quality of the surgical field was worse in the patients injected with normal saline (P = 0.0179). Infiltration of septal mucoperichondrium with lidocaine and adrenaline instead of normal saline was not advantageous in terms of objective parameters tested, including bleeding amount and duration of surgery as well as the of the total mucosal injury rate in septoplasty procedure.

    Hearing loss is considered the most common congenital disease and the prevalence of neonatal deafness can be estimated between 1 and 2 cases per 1000 live births. Infant deafness must be diagnosed as early as possible and an effective therapeutic intervention needs to be carried out in order to avoid the serious consequences of hearing deprivation during the evolutionary period: alterations in the development of central auditory pathways and lack of language acquisition. The cochlear implant (CI) has proved to be the best instrument to solve the problem of auditory deprivation. In particular, the bilateral CI gives the patient access to binaural hearing which results in benefits in terms of sound localisation and discrimination. The optimal age of application of the CI is a widely discussed topic in the scientific community and the current guidelines indicate a period between 12 and 24 months of age, even though the supporters of the application before 12 months of age are nowadays increasing. The study is observational, retrospective, monocentric. 49 paediatric patients (<18 years) with simultaneous bilateral CIs were included. The audiometric threshold and speech tests were carried out during the follow-up 3, 6 and 12 months after the CIs activation and when the patient reached 2 years of age. The statistical analysis showed that undergoing bilateral implantation surgery before 2 years of age allows a satisfactory audiometric performance, while there are no particular benefits in performing the surgery before 1 year of age. As far as the speech outcome is concerned, the statistical analysis didn't show significant correlation between the earlier age of implantation and better speech performance if the operation is carried out before 2.5 years of age. The results of the study indicate that the optimal age to perform the simultaneous bilateral CIs surgery is between 12 and 24 months, without demonstrating any particular benefit in carrying out the procedure before

    This dose-finding study aimed to determine the minimum effective volume in 90% of patients (MEV90) of lidocaine 1.5% with epinephrine 5 μg/mL for ultrasound-guided costoclavicular block. Using an in-plane technique and a lateral-to-medial direction, the block needle was positioned in the middle of the 3 cords of the brachial plexus in the costoclavicular space. The entire volume of lidocaine was deposited in this location. Dose assignment was carried out using a biased-coin-design up-and-down sequential method, where the total volume of local anesthetic administered to each patient depended on the response of the previous one. In case of failure, the next subject received a higher volume (defined as the previous volume with an increment of 2.5 mL). If the previous patient had a successful block, the next subject was randomized to a lower volume (defined as the previous volume with a decrement of 2.5 mL), with a probability of b = 0.11, or the same volume, with a probability of 1 - b = 0.89. Success was defined, at 30 minutes, as a minimal score of 14 of 16 points using a sensorimotor composite scale. Patients undergoing surgery of the elbow, forearm, wrist, or hand were prospectively enrolled until 45 successful blocks were obtained. This clinical trial was registered with ClinicalTrials.gov (ID NCT02932670). Fifty-seven patients were included in the study. Using isotonic regression and bootstrap confidence interval, the MEV90 for ultrasound-guided costoclavicular block was estimated to be 34.0 mL (95% confidence interval, 33.4-34.4 mL). All patients with a minimal composite score of 14 points at 30 minutes achieved surgical anesthesia intraoperatively. For ultrasound-guided costoclavicular block, the MEV90 of lidocaine 1.5% with epinephrine 5 μg/mL is 34 mL. Further dose-finding studies are required for other concentrations of lidocaine, other local anesthetic agents, and multiple-injection techniques.

    Full Text Available Purpose: The efficacy and safety of peribulbar anaesthesia was assessed using a combination of lidocaine, bupivacaine and clonidine during eye surgery. Methods: We prospectively studied 100 vitreo-retinal surgical procedures performed by several surgeons. The exclusion criteria included age below 30 years and, axial length of the orbit above 28 mm. Peribulbar was performed using Hamilton′s technique. A mixed anaesthetic solution of equal quantity of lidocaine 2% and bupivacaine 0.5% with clonidine (1mg/kg was injected. Patients received a mean volume of 14.5 ml ± 3.5 of the mixture. Akinesia and analgesia were assessed 15 minutes later by the surgeon. Whenever required, supplemental lidocaine 2% (3 ml by sub- Tenon infiltration was added by the surgeon. Supplemental injections were given only to patients who failed to develop analgesia. Results: The mean age of patients (male 52%, female 48% was 66 years ± 10 (mean ± SD, range 44-90. The 100 surgical procedures were made up of vitrectomy ± gas ± silicone oil (22/100, vitrectomy and lensectomy (6/100, vitrectomy and epiretinal membrane ± laser coagulation ± gas ± silicone oil (35/100, scleral buckling or encircling ± gas (36/100, and cryosurgery ± gas (1/100. Analgesia was adequate throughout surgery without any supplementation in 85% of cases and with a sub-Tenon infiltration in 99%. Akinesia was complete in 84%, mild in 12% and absent in 4% of cases. The sub-Tenon injection was performed in 15% of cases. Three patients (3% were agitated during surgery. No neurologic or cardiac complication was seen. In one patient, the systolic blood pressure decreased from 170 to 110 mmHg, 30 minutes after the institution of the peribulbar block. Conclusion: Our results show that peribulbar anaesthesia in the proposed mixture offers excellent analgesia in 85% of patients, and in 99% of the patients when supplemented by a subtenon injection. The current mixture of lidocaine, bupivacaine and

    It has been demonstrated that chronic opium abusers have lower thresholds for pain. In this study we sought to determine whether chronic opium abuse has any effect on the duration of spinal block by local anesthetics. In a case-controlled study, 50 opium abusers and 50 nonabusers undergoing lower abdomen operations were selected from among the patients admitted to a university hospital for elective surgery. All patients received 100 mg hyperbaric preservative-free 5% lidocaine in dextrose, intrathecally. The duration of anesthesia was much shorter in the opium abusers (60 +/- 7 min) than in the nonabusers (83 +/- 10 min) (P opium abusers.

    Full Text Available Background and the purpose of the study: Opioids are usually used in regional anesthesia, with or without local anesthetics to improve the regional block or postoperative pain control. Since no data are available on fentanyl's effect on the onset time of lidocaine interscalene anesthesia, the purpose of this study was to examine its effect on the onset time of sensory and motor blockade during interscalene anesthesia.  Methods: In a prospective, randomized, double-blind study, ninety patients scheduled for elective shoulder, arm and forearm surgeries under an  interscalene brachial plexus block .They were randomly allocated to receive either 30 ml of  1.5 % lidocaine with 1.5 ml of isotonic saline  (control group, n = 39 or 30 ml of 1.5%  lidocaine with 1.5 ml (75µg of  fentanyl (fentanyl group,n=41. Then the onset time of sensory and motor blockades of the shoulder, arm and forearm were evaluated every 60 sec. The onset time of the sensory and motor blockades was defined as the time between the last injection and the total abolition of the pinprick response and complete paralysis. The duration of sensory blocks were considered as the time interval between the administration of the local anesthetic and the first postoperative pain sensation. Results: Ten patients were excluded because of unsuccessful blockade or unbearable pain during the surgery. The onset time of the sensory block was significantly faster in the fentanyl group (186.54± 62.71sec compared with the control group (289.51± 81.22, P < 0.01. The onset times of the motor block up to complete paralysis in forearm flexion was significantly faster in the fentanyl group (260.61± 119.91sec than the control group (367.08± 162.43sec, P < 0.01 There was no difference in the duration of the sensory block between two groups. Conclusion: Results of the study showed that the combination of 75 µg fentanyl and 1.5% lidocaine solution accelerated the onset of sensory and motor

    This randomized, double-blind controlled study evaluated the effectiveness of sodium bicarbonate-buffered lidocaine on reducing pain during imaging-guided breast biopsies. This prospective, HIPAA-compliant study randomly assigned 85 women undergoing ultrasound- or stereotactic-guided core-needle breast biopsies to receive intradermally and intraparenchymally either 1% lidocaine buffered with sodium bicarbonate (9:1 ratio) (bicarbonate study group) or 1% lidocaine alone (control group). Pain was evaluated using a 0-to-10 Likert pain scale during both intradermal and intraparenchymal anesthesia injections and during tissue sampling. Prebiopsy breast pain, anxiety, medical history, demographics, biopsy type, radiologist level of training, breast density, and lesion histology were recorded. Data were analyzed using analysis of variance and analysis of covariance. Unadjusted mean pain scores were 1.47 and 2.07 (study and control groups, respectively; P = .15) during intradermal injections, and 1.84 and 2.98 (study and control groups, respectively; P = .03) during intraparenchymal injections. Tissue sampling mean pain scores were .81 and 1.71 (study and control groups, respectively; P = .07). Moderator analyses found (1) among patients with preprocedural pain, those in the bicarbonate group experienced less intradermal injection pain (0.85 ± 1.23) than patients in the control group (2.50 ± 2.09); (2) among patients with fatty or scattered fibroglandular tissue, those in the bicarbonate group (1.35 ± 1.95) experienced less intraparenchymal injection pain than the control group (3.52 ± 3.13); and (3) during ultrasound-guided biopsies, patients in the bicarbonate group experienced less tissue-sampling pain (0.23 ± 0.63) than the control group (1.79 ± 3.05). Overall, buffering lidocaine with sodium bicarbonate significantly reduced pain during intraparenchymal injections, and additional pain reduction was found in certain patient subgroups during intradermal

    Objective: To study the clinical and imaging features of chlamydial pneumonia in newborns. Methods: Medical records,chest X-Ray and CT findings of 17 neonates with chlamydia pneumonia were reviewed. The age was ranged from 9.0 to 28.0 days with mean of (16.8 ± 5.8) days. There were 11 males and 6 females. Sixteen were full term infants and one was born post term. All babies were examined with chest X-ray film, and 13 patients also underwent chest CT scan. Serologic test using immunofluorescence method for Chlamydia IgG and IgM antibodies were performed in all patients. Results: All newborns presented with cough but without fever. Positive results of the serologic tests were demonstrated. Chest films showed bilateral hyperventilation in 10 patients, diffuse reticular nodules in 10 patients including nodules mimicking military tuberculosis in 7 patients, and accompanying consolidation in 9 patients. CT features included interstitial reticular nodules in 13 patients with size, density, and distribution varied. Subpleural nodules (11 patients) and fusion of nodules (10 patients) predominated. Bilateral hyperinflation was found in 10 patients, which combined with infiltration in 12 patients, thickening of bronchovascular bundles in 10 patients, and ground glass sign in 5 patients. No pleural effusion and lymphadenopathy was detected in any patient. Conclusions: Bilateral hyperinflation and diffuse interstitial reticular nodules were the most common imaging features of neonatal chlamydial pneumonia. The main clinical characteristic of neonatal chlamydial pneumonia is respiratory symptoms without fever, which is helpful to its diagnosis. (authors)

    Full Text Available Abnormalities of the upper airway tract lead to congenital high airway obstruction and may complicate neonatal airway management in the delivery room. Congenital complete tracheal rings are a rare and unusual tracheal anomaly, usually presenting in the neonate or infant as respiratory distress. The clinical presentation can vary from almost asymptomatic patients to near-fatal airway obstruction. It may exist as an isolated entity, or in association with other congenital malformations, in particular, cardiac anomalies along with vascular rings and pulmonary slings. Other associated anomalies have also been reported, for example, chromosomal anomalies, malformation of other parts of the respiratory tract, esophagus and skeletal systems. Here, we report an extreme case of VACTERL/TACRD association presented with congenital complete tracheal ring, encephalocele, bilateral radial agenesis with absent thumbs, equinovalgus deformity on right foot, low-set ears and micrognathia.

    Pediatric cardiac surgery, especially for small neonates, typically requires blood products to counter hemodilution during cardiopulmonary bypass. Children with congenital heart defects whose families adhere to faith-based proscriptions against blood transfusion therefore represent a challenging surgical population. Here, we report the case of a ten-day-old, 3.6-kg patient of Jehovah's Witness faith, who was diagnosed with unilateral pulmonary artery discontinuity, bilateral patent ductus arteriosus, and an otherwise structurally normal heart. Pulmonary artery reimplantation was successfully performed without giving blood products. This case adds to previous reports of successful bloodless cardiac surgery in neonates and describes the specific strategies that contributed to successful pulmonary artery reimplantation. © The Author(s) 2015.

    The aim of the study was to investigate whether children with bilateral conductive hearing loss benefit from their second device (i.e., the bilateral bone conduction device [BCD]). Speech recognition in noise was assessed in 10 children fitted with bilateral BCDs during childhood. Speech recognition was measured in 2 conditions with both BCDs active. Spatial resolution was tested with the Minimum Audible Angle test in the bilateral and monaural listening conditions. Children demonstrated an improvement in speech recognition when speech was presented from the front and noise was presented from the right-hand side as compared with both speech and noise being presented from the front. The minimum audible angle decreased from 57° in the best monaural condition to 13° in the bilateral condition. The audiological outcomes demonstrate the advantage of bilateral BCD fitting in children with bilateral conductive hearing loss.

  12. Acute Bilateral Superior Branch Vestibular Neuropathy

    Dario A. Yacovino

    2018-05-01

    Full Text Available The rapid onset of a bilateral vestibular hypofunction (BVH is often attributed to vestibular ototoxicity. However, without any prior exposure to ototoxins, the idiopathic form of BVH is most common. Although sequential bilateral vestibular neuritis (VN is described as a cause of BVH, clinical evidence for simultaneous and acute onset bilateral VN is unknown. We describe a patient with an acute onset of severe gait ataxia and oscillopsia with features compatible with acute BVH putatively due to a bilateral VN, which we serially evaluated with clinical and laboratory vestibular function testing over the course of 1 year. Initially, bilateral superior and horizontal semicircular canals and bilateral utricles were impaired, consistent with damage to both superior branches of each vestibular nerve. Hearing was spared. Only modest results were obtained following 6 months of vestibular rehabilitation. At a 1-year follow-up, only the utricular function of one side recovered. This case is the first evidence supporting an acute presentation of bilateral VN as a cause for BVH, which would not have been observed without critical assessment of each of the 10 vestibular end organs.

    We reported a case of cryptococcal meningitis presenting with bilateral optic neuropathy in an immunocompetent patient. A 64-year-old Malay gentleman with no medical comorbidities presented with acute bilateral blurring of vision for a week, which was associated with generalised throbbing headache and low grade fever. He also had som-nolence and altered consciousness. Visual acuity in both eyes was no perception of light with poor pupillary reflexes. Extraocular muscle movements were normal. Anterior segments were unremarkable bilaterally. Fundoscopy revealed bilateral optic disc swelling. CT scan of the brain showed multifocal infarct, but no meningeal enhancement or mass. Cerebrospinal fluid opening pressure was normal, while its culture grew Cryptococcus neoformans. A diagnosis of cryptococcal meningitis with bilateral optic neuropathy was made. Patient was treated with a six-week course of intravenous flu-conazole and started concomitantly on a fortnight's course of intravenous amphotericin B. After that, his general condition improved, but there was still no improvement in his visual acuity. On reviewing at two months post-initiation of treatment, fundi showed bilateral optic atrophy. Bilateral optic neuropathy secondary to cryptococcal meningitis was rare. The prognosis was guarded due to the sequelae of optic atrophy. Anti-fungal medication alone may not be sufficient to manage this condition. However, evidence for other treatment modalities is still lacking and further clinical studies are required.

    Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originating from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning and surgical strategy. A 21-year-old male presented with increasing bilateral nasal obstruction and discharge. Examination revealed tumours bilaterally and imaging demonstrated non-contiguous tumours. Pre-operative angiography showed strictly ipsilateral vascular supplies requiring bilateral embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting with bilateral symptoms. Our management, including successful pre-operative planning, enabled one-step total removal of both tumours and rapid patient recovery.

    Full Text Available Molecular complexation is a strategy used to modify the physicochemical or biopharmaceutical properties of an active pharmaceutical ingredient. Solvent assisted grinding is a common method used to obtain solid complexes in the form of cocrystals. Lidocaine is a drug used as an anesthetic and for the treatment of chronic pain, which bears in its chemical structure an amide functional group able to form hydrogen bonds. Polyphenols are used as cocrystal coformers due to their ability to form O–H···X (X = O, N hydrogen bond interactions. The objective of this study was to exploit the ability of phloroglucinol to form molecular complexes with lidocaine by liquid assisted grinding. The formation of the complex was confirmed by the shift of the O–H and C=O stretching bands in the IR spectra of the polycrystalline ground powders, suggesting the formation of O–H···O=C hydrogen bonds. Hydration of the complexes also was confirmed by IR spectroscopy and by powder X-ray diffraction. The molecular structure was determined by single crystal X-ray diffraction.

    To determine if barbiturates would protect brain at high doses of radiation, survival rates in rats that received whole-brain x-irradiation during pentobarbital- or lidocaine-induced anesthesia were compared with those of control animals that received no medication and of animals anesthetized with ketamine. The animals were shielded so that respiratory and digestive tissues would not be damaged by the radiation. Survival rates in rats that received whole-brain irradiation as a single 7500-rad dose under pentobarbital- or lidocaine-induced anesthesia was increased from between from 0% and 20% to between 45% and 69% over the 40 days of observation compared with the other two groups (p less than 0.007). Ketamine anesthesia provided no protection. There were no notable differential effects upon non-neural tissues, suggesting that pentobarbital afforded protection through modulation of ambient neural activity during radiation exposure. Neural suppression during high-dose cranial irradiation protects brain from acute and early delayed radiation injury. Further development and application of this knowledge may reduce the incidence of radiation toxicity of the central nervous system (CNS) and may permit the safe use of otherwise unsafe doses of radiation in patients with CNS neoplasms

    In this study, the authors evaluate the use of a 10% metronidazole and 2% lidocaine ointment, using a lanolin base and mint as flavoring, to treat alveolitis in humans. Twenty-five patients, with a diagnosis of alveolitis, were treated in the following way: locoregional anesthesia; surgical cleaning of the socket with alveolar curettes; saline solution irrigation with a 20 ml disposable syringe; and complete filling of the socket with the ointment. The analysis of the results showed that the painful symptoms were severe before and on the day of the treatment in 17 (68%) of the 25 patients treated. Post-treatment analysis presented 2 patients (18%) with severe painful symptoms after 24 h of the treatment and complete remission of painful symptoms after 48 h of the treatment with the ointment. Based on the results, it is possible to conclude that the 10% metronidazole and 2% lidocaine ointment, with mint flavoring and lanolin as a base, can be used to treat alveolitis.

    Aromatic hydroxylation reactions, which are mainly catalyzed by cytochrome P450 (CYP) enzymes in vivo, are some of the most important reactions of Phase I metabolism, because insertion of a hydroxyl group into a lipophilic drug compound increases its hydrophilicity and prepares it for subsequent Phase II metabolic conjugation reactions as a prerequisite to excretion. Aromatic hydroxylation metabolites of pharmaceuticals may be obtained through various synthetic and enzymatic methods Electrochemical oxidation is an alternative with advantages in terms of mild reaction conditions and less hazardous chemicals. In the present study, we report that aromatic hydroxylation metabolites of lidocaine can be readily obtained electrochemically under aqueous acidic conditions at platinum electrodes. Our results show that the dominant N-dealkylation reaction can be suppressed by decreasing the solution pH below 0.5 resulting in selective 3-hydroxylidocaine, which is an in vivo metabolite of lidocaine. Experiments in 18 O labelled water indicated that water is the primary source of oxygen, while dissolved molecular oxygen contributes to a minor extent to the hydroxylation reaction.

    A modified protocol of uterine fibroid embolization (UFE) is proposed for alleviating the postinterventional pain. This randomized and double-blinded clinical trial is to evaluate the effectiveness of intra-arterial infusion of dilute lidocaine for postinterventional pain relief in UFE. Forty-six patients who underwent UFE were randomly grouped equally. In the test group, after the poly(vinyl alcohol) embolization was complete, a dilute lidocaine solution with 40 mg in 6.0 ml, 3.0 ml for each side or 4.0 and 2.0 ml for two sides, was given through the catheter. In the control group, the patients received 6.0 ml of saline solution as a placebo. A simple pain degree classification method for patient self-evaluation was developed. A questionnaire was completed by each patient to record the degree of pain during five periods; these were during the procedure, the first 12 h, the second 12 h, between 24 and 48 h, and between 48 and 72 h. The numbers of patients with the same degree of pain in the five time segments from the two groups were statistically compared. Compared with the control group, the patients in the test group experienced less pain within 48 h after the procedure (p<0.01). The results suggest that this improved UFE protocol is a simple approach to prevent the acute postinterventional pain of UFE. (orig.)

    The aim of this study was to determine the viability and cardiorespiratory effects of the association of epidural alpha-2 adrenergic agonists and lidocaine for ovariohysterectomy (OH) in bitches. Forty-two bitches were spayed under epidural anesthesia with 2.5 mg/kg body weight (BW) of 1% lidocaine with adrenaline (CON) or in association with 0.25 mg/kg BW of xylazine (XYL), 10 μg/kg BW of romifidine (ROM), 30 μg/kg BW of detomidine (DET), 2 μg/kg BW of dexmedetomidine (DEX), or 5 μg/kg BW of clonidine (CLO). Heart rate (HR), respiratory rate (fR) and arterial pressures were monitored immediately before and every 10 min after the epidural procedure. Blood gas and pH analysis were done before, and at 30 and 60 min after the epidural procedure. Animals were submitted to isoflurane anesthesia if they presented a slightest sign of discomfort during the procedure. Time of sensory epidural block and postoperative analgesia were evaluated. All animals in CON and DEX, 5 animals in ROM and CLO, 4 animals in XYL, and 3 in DET required supplementary isoflurane. All groups, except CLO, showed a decrease in HR. There was an increase in arterial pressures in all groups. Postoperative analgesia lasted the longest in XYL. None of the protocols were totally efficient to perform the complete procedure of OH; however, xylazine provided longer postoperative analgesia than the others. PMID:23277701

    The deletion of phenylalanine 1486 (F1486del) in the human cardiac voltage-gated sodium channel (hNav1.5) is associated with fatal long QT (LQT) syndrome. In this study we determined how F1486del impairs the functional properties of hNav1.5 and alters action potential firing in heterologous expression systems (human embryonic kidney (HEK) 293 cells) and their native cardiomyocyte background. Cells expressing hNav1.5-F1486del exhibited a loss-of-function alteration, reflected by an 80% reduction of peak current density, and several gain-of-function alterations, including reduced channel inactivation, enlarged window current, substantial augmentation of persistent late sodium current and an increase in ramp current. We also observed substantial action potential duration (APD) prolongation and prominent early afterdepolarizations (EADs) in neonatal cardiomyocytes expressing the F1486del channels, as well as in computer simulations of myocyte activity. In addition, lidocaine sensitivity was dramatically reduced, which probably contributed to the poor therapeutic outcome observed in the patient carrying the hNav1.5-F1486del mutation. Therefore, despite the significant reduction in peak current density, the F1486del mutation also leads to substantial gain-of-function alterations that are sufficient to cause APD prolongation and EADs, the predominant characteristic of LQTs. These data demonstrate that hNav1.5 mutations can have complex functional consequences and highlight the importance of identifying the specific molecular defect when evaluating potential treatments for individuals with prolonged QT intervals.

    Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report a rare case of bilateral segmental renal infarction secondary to FMD in a young male patient. His initial presentation with loin pain and pyrexia resulted in a delay in the definitive diagnosis of FMD. He was successfully treated with bilateral balloon angioplasty. The delayed diagnosis in this patient until the condition had progressed to bilateral renal infarcts highlights the need for prompt investigation and diagnosis of suspected cases of FMD.

    The relative preventative efficacy of amiodarone and lidocaine for ventricular fibrillation (VF) after release of an aortic cross-clamp (ACC) during open heart surgery has not been determined. This meta-analysis was designed to systematically evaluate the influence of amiodarone, lidocaine, or placebo on the incidence of VF after ACC. Prospective randomized controlled trials (RCTs) that compared the VF-preventative effects of amiodarone with lidocaine, or amiodarone or lidocaine with placebo were included. PubMed, EMBASE, and the Cochrane Library were searched for relevant RCTs. Fixed or randomized effect models were applied according to the heterogeneity of the data from the selected studies. We included eight RCTs in the analysis. Pooled results suggested that the preventative effects of amiodarone and lidocaine were comparable (relative risk (RR)=1.12, 95% confidence interval (CI): 0.70 to 1.80, P=0.63), but both were superior to the placebo (amiodarone, RR=0.71, 95% CI: 0.51 to 1.00, P=0.05; lidocaine, RR=0.63, 95% CI: 0.46 to 0.88, P=0.006). The percentage of patients requiring electric defibrillation counter shocks (DCSs) did not differ significantly among patients administered amiodarone (RR=0.21, 95% CI: 0.04 to 1.19, P=0.08), lidocaine (RR=2.44, 95% CI: 0.13 to 44.02, P=0.55), or the placebo (RR=0.56, 95% CI: 0.25 to 1.25, P=0.16). Amiodarone and lidocaine are comparably effective in preventing VF after ACC, but the percentage of patients who subsequently require DCSs does not differ among those administered amiodarone, lidocaine, or placebo.

    Full Text Available Background: Successful treatment of complex regional pain syndrome type 1 (CRPS-1 requires a coordinated, multidisciplinary approach. Physical rehabilitation is an important component of long-term treatment. Unfortunately, patients with significant allodynia or hyperalgesia characteristic of CRPS-1 often have difficulty progressing through a physical therapy (PT regimen. In most adults with CRPS-1, the treatment of choice is PO opioids. Objective: This article presents a case report of the use of the lidocaine patch 5%, a targeted peripheral analgesic, in a pediatric patient and its effects on reducing pain, improving the patient's overall attitude, and facilitating compliance with ongoing PT. Results: A 10-year-old girl developed CRPS-1 after arthroscopic surgery for a sprained ankle. Attempts at PT were unsuccessful due to inadequate pain relief from various treatment modalities. Therapy with the lidocaine patch 5% was initiated and resulted in significant pain relief, improvements in the patient's attitude, and progress with PT. Conclusion: This case report of a child with CRPS-1 showed that therapy with lidocaine patch 5% may be efficacious in treating children with pain resulting from CRPS-1, thereby increasing the success of PT.

    The purpose of this study was to compare the anesthetic efficacy of 0.5% bupivacaine with 1:200,000 epinephrine with that of 2% lidocaine with 1:100,000 epinephrine during pulpectomy in patients with irreversible pulpitis in mandibular posterior teeth. Seventy volunteers, patients with irreversible pulpitis admitted to the Emergency Center of the School of Dentistry at the University of São Paulo, randomly received a conventional inferior alveolar nerve block containing 3.6 mL of either 0.5% bupivacaine with 1:200,000 epinephrine or 2% lidocaine with 1:100,000 epinephrine. During the subsequent pulpectomy, we recorded the patients' subjective assessments of lip anesthesia, the absence/presence of pulpal anesthesia through electric pulp stimulation, and the absence/presence of pain through a verbal analog scale. All patients reported lip anesthesia after the application of either inferior alveolar nerve block. By measuring pulpal anesthesia success with the pulp tester, lidocaine had a higher success rate (42.9%) than bupivacaine (20%). For patients reporting none or mild pain during pulpectomy, the success rate of bupivacaine was 80% and lidocaine was 62.9%. There were only statistically significant differences to the success of pulpal anesthesia. Neither of the solutions resulted in an effective pain control during irreversible pulpitis treatments of mandibular molars. Copyright © 2012 American Association of Endodontists.

    The pain on propofol injection is considered to be a common and difficult to eliminate problem in children. In this study, we aimed to compare the efficacy of pretreatment with tramadol 1 mg.kg(-1)and propofol-lidocaine 20 mg mixture for prevention of propofol induced pain in children. One hundred and twenty ASA I-II patients undergoing orthopedic and otolaryngological surgery were included in this study and were divided into three groups with random table numbers. Group C (n=39) received normal saline placebo and Group T (n=40) received 1 mg.kg(-1) tramadol 60 sec before propofol (180 mg 1% propofol with 2 ml normal saline) whereas Group L (n=40) received normal saline placebo before propofol-lidocaine mixture (180 mg 1% propofol with 2 ml %1 lidocaine). One patient in Group C was dropped out from the study because of difficulty in inserting an iv cannula. Thus, one hundred and nineteen patients were analyzed for the study. After given the calculated dose of propofol, a blinded observer assessed the pain with a four-point behavioral scale. There were no significant differences in patient characteristics and intraoperative variables (p>0.05) except intraoperative fentanyl consumption and analgesic requirement one hr after surgery among the groups (ppain when compared with control group. Moderate and severe pain were found higher in control group (ppain was 79.4% in the control group, 35% in tramadol group, 25% in lidocaine group respectively (ppain when compared to placebo in children.

    Various effective methods are available for perioperative pain control in osteosynthesis surgery, but they are seldom applied intraoperatively. The aim of this study was to evaluate a biodegradable poly([d,l]-lactide-co-glycolide) (PLGA)/lidocaine nanofibrous membrane for perioperative pain control in rib fracture surgery. Scanning electron microscopy showed high porosity of the membrane, and an ex vivo high-performance liquid chromatography study revealed an excellent release profile for both burst and controlled release of lidocaine within 30days. Additionally, the PLGA/lidocaine nanofibrous membrane was applied in an experimental rabbit rib osteotomy model. Implantation of the membrane around the osteotomized rib during osteosynthesis surgery resulted in a significant increase in weight gain, food and water consumption, and daily activity compared to the study group without the membrane. In addition, all osteotomized ribs were united. Thus, application of the PLGA/lidocaine nanofibrous membrane may be effective for sustained relief of pain in oeteosynthesis surgery.

    To study the development of the bilateral benefit in children using bilateral cochlear implants by measurements of speech recognition and sound localization. Bilateral and unilateral speech recognition in quiet, in multi-source noise, and horizontal sound localization was measured at three occasions during a two-year period, without controlling for age or implant experience. Longitudinal and cross-sectional analyses were performed. Results were compared to cross-sectional data from children with normal hearing. Seventy-eight children aged 5.1-11.9 years, with a mean bilateral cochlear implant experience of 3.3 years and a mean age of 7.8 years, at inclusion in the study. Thirty children with normal hearing aged 4.8-9.0 years provided normative data. For children with cochlear implants, bilateral and unilateral speech recognition in quiet was comparable whereas a bilateral benefit for speech recognition in noise and sound localization was found at all three test occasions. Absolute performance was lower than in children with normal hearing. Early bilateral implantation facilitated sound localization. A bilateral benefit for speech recognition in noise and sound localization continues to exist over time for children with bilateral cochlear implants, but no relative improvement is found after three years of bilateral cochlear implant experience.

    To assess the cardiovascular changes of a continuous rate infusion of lidocaine in calves anesthetized with xylazine, midazolam, ketamine and isoflurane during mechanical ventilation. Prospective, randomized, cross-over, experimental trial. A total of eight, healthy, male Holstein calves, aged 10 ± 1 months and weighing 114 ± 11 kg were included in the study. Calves were administered xylazine followed by ketamine and midazolam, orotracheal intubation and maintenance on isoflurane (1.3%) using mechanical ventilation. Forty minutes after induction, lidocaine (2 mg kg⁻¹ bolus) or an equivalent volume of saline (0.9%) was administered IV followed by a continuous rate infusion (100 μg kg⁻¹ minute⁻¹) of lidocaine (treatment L) or saline (treatment C). Heart rate (HR), systolic, diastolic and mean arterial pressures (SAP, DAP and MAP), central venous pressure (CVP), mean pulmonary arterial pressure (mPAP), pulmonary arterial occlusion pressure (PAOP), cardiac output, end-tidal carbon dioxide (Pe'CO2 ) and core temperature (CT) were recorded before lidocaine or saline administration (Baseline) and at 20-minute intervals (T20-T80). Plasma concentrations of lidocaine were measured in treatment L. The HR was significantly lower in treatment L compared with treatment C. There was no difference between the treatments with regards to SAP, DAP, MAP and SVRI. CI was significantly lower at T60 in treatment L when compared with treatment C. PAOP and CVP increased significantly at all times compared with Baseline in treatment L. There was no significant difference between times within each treatment and between treatments with regards to other measured variables. Plasma concentrations of lidocaine ranged from 1.85 to 2.06 μg mL⁻¹ during the CRI. At the studied rate, lidocaine causes a decrease in heart rate which is unlikely to be of clinical significance in healthy animals, but could be a concern in compromised animals. © 2013 Association of Veterinary Anaesthetists

    Full Text Available Bilateral tubal pregnancy is very rare and occurs in only 1 out of every 200,000 spontaneous pregnancies. In this case, a 29-year-old woman with a history of primary infertility underwent treatment with human menopausal gonadotropin (hMG-human chorionic gonadotropin (hCG, and became pregnant. A gestational sac (GS was not detected in the uterus and transvaginal ultrasonography (USG revealed GS with fetal heartbeat in the left adnexa at 7 weeks and 6 days of gestation. The patient underwent laparoscopic surgery and ultimately, bilateral tubal pregnancy was diagnosed. Consequently, bilateral fallopian tube resection was performed. Afterwards, she conceived by assisted reproductive technology (ART and delivered vaginally. This case suggests that even if a GS is found in one fallopian tube by USG, it is important to evaluate the other fallopian tube carefully.

    Nasolabial cysts are rare, nonodontogenic, soft-tissue, developmental cysts occurring inferior to the nasal alar region. They are thought to arise from remnants of the nasolacrimal ducts and they are frequently asymptomatic. We report a rare case of bilateral nasolabial cysts accompanied by bilateral chronic dacryocystitis. A 48-year-old woman suffering from bilateral chronic dacryocystitis was referred to our department for endonasal dacryocystorhinostomy. She had undergone external dacryocystorhinostomy on the left side a few years earlier. Physical examination and computed tomography scan revealed nasolabial cysts bilaterally inferior to the nasal alar region. The cysts were removed via a sublabial approach and endoscopic dacryocystorhinostomy was performed on the right side. Ten months after surgery, the patient was asymptomatic. There may be a correlation, due to embryological reasons, between the presence of nasolabial cysts and the presence of chronic dacryocystitis. Both can be corrected surgically, under the same anaesthesia, without visible scar formation.

  1. THE EUROPEAN UNION’S BILATERAL APPROACH

    Full Text Available The EU is a world economic power and a major trading partner for most countries. All the time, this region has been interested and has acted towards a free and fair trade. The decrease and even the elimination of tariff and non-tariff barriers in the world trade are among the main objectives of the EU strategy for international trade. At the moment, the elusive outcome of the WTO Doha Round has led to the proliferation of bilateral trade agreements worldwide. Although the EU remains committed to further development of the multilateral trading system, however, the EU still has appealed also to the development of bilateral trade relations. The aim of this paper is to illustrate the current bilateral dimension of the common commercial policy of the EU. In conclusion, to describe this bilateral approach of the EU we are using one word, namely “diversity”.

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

    Full Text Available We present a case study of a person (63 year-old man, who has been using statins for 18 years, with rhabdomyolysis of the bilateral adductor muscles associated with strenuous and prolonged eccentric exercises (hiking in a hot environment. Clinical examination showed predominantly on the right side muscle swelling and palpational pain of the bilateral adductor muscle groups and bilateral tibial edema. His serum creatine kinase (CK level was 12218 IU/L. T2-weighted magnetic resonance (MR images showed a high signal intensity in the bilateral adductor muscles of the hip. The patient did not develop complications and returned to his previous performance level in 30 days following adequate hydration and resting of the affected muscles. Strenuous eccentric exercise should be avoided during the course of statin use and clinicians should be aware of present observations when considering the significance of acute CK elevations in patients on statin treatment

    Full Text Available Spontaneous bilateral ectopic gestation is very rare. The authors report a case diagnosed and taken care of at Yalgado Ouedraogo Teaching Hospital, Ouagadougou. It was a 30-year-old patient with no known pathological history. She had presented at the obstetric emergencies with a state of hypovolemic shock by haemoperitoneum with digestive disorders, pelvic pain, vaginal bleeding, and a mention of delayed menstruation. The ultrasound coupled with the urinary immunological pregnancy test confirmed the diagnosis of ruptured ectopic pregnancy and a bilateral form was suspected. A laparotomy in emergency confirmed the diagnosis of bilateral ectopic gestation with a right ampullary unruptured pregnancy and a left isthmic ruptured gestation. A bilateral salpingectomy was performed and counseling was made for the use of medical help of procreation in case of future need of pregnancy.

    An intravenous (IV) overdose of pentobarbital sodium is the most commonly used method of euthanasia in veterinary medicine. However, this compound is not available in many countries or rural areas resulting in usage of alternative methods such as intrathecal lidocaine administration after IV anesthesia. Its safety and efficacy as a method of euthanasia have not been investigated in the horse. To investigate changes in mean arterial blood pressure and electrical activity of the cerebral cortex, brainstem, and heart during intrathecal administration of lidocaine. Our hypothesis was that intrathecal lidocaine affects the cerebral cortex and brainstem before affecting cardiovascular function. Eleven horses requiring euthanasia for medical reasons. Prospective observational study. Horses were anesthetized with xylazine, midazolam, and ketamine; and instrumented for recording of electroencephalogram (EEG), electrooculogram (EOG), brainstem auditory evoked response (BAER), and electrocardiogram (ECG). Physical and neurological (brainstem reflexes) variables were monitored. Mean arterial blood pressure was recorded throughout the study. Loss of cerebro-cortical electrical activity occurred up to 226 seconds after the end of the infusion of lidocaine solution. Cessation of brainstem function as evidenced by a lack of brainstem reflexes and disappearance of BAER occurred subsequently. Undetectable heart sounds, nonpalpable arterial pulse, and extremely low mean arterial blood pressure supported cardiac death; a recordable ECG was the last variable to disappear after the infusion (300-1,279 seconds). Intrathecal administration of lidocaine is an effective alternative method of euthanasia in anesthetized horses, during which brain death occurs before cardiac death. Copyright © 2015 The Authors.

    A case of bilateral calcaneal epiphysiolysis in a six-month-old female Dobermann Pinscher is described in this report. The absence of a traumatic event and the clinical, radiographic and histopathological abnormalities led us to the diagnosis of simultaneous bilateral epiphysiolysis of the calcaneus. A tension band and a type II transarticular external fixator were placed. The clinical signs were resolved only temporarily because of the gravity of the bone changes.

    Renal cell carcinoma (RCC) is a malignant lethal tumour with high potential of metastasis. However, metastasis from RCC to the skin is much less common. It is virtually a sign of poor prognosis. We represent a 42 years old man with bilateral RCC of clear cell type followed by metastasis to the scalp one month later. In this case the relatively young age of the patient, bilaterality of RCC and occurance of skin metastasis in the absence of recurrent kidney tumour are interesting.

    2018-01-01

    Full Text Available Bilateral uveal effusion syndrome associated with bilateral acute retinal necrosis is a diagnostic and therapeutic challenge. A 52 year old man presented with bilateral angle closure with choroidal detachment. With restricted fundus view, parenteral steroid was started. During close follow up bilateral discrete areas of peripheral retinitis were noted. Parenteral steroids were promptly stopped and parenteral antivirals with oral steroids were continued. It showed healing response with nil recurrences till last follow up. Aggressive treatment of bilateral uveal effusion with parenteral steroids can cause progression of bilateral acute retinal necrosis leading to phthisis bulbi. However early diagnosis, prompt intervention and close follow up are the key elements to therapeutic success even during diagnostic surprises and avoid costly mistakes.

    To present a case of a patient with simultaneous bilateral retinal detachments treated successfully with bilateral pneumatic retinopexy. Case report. This is a case of an otherwise healthy 49-year-old woman with no remarkable ocular history that presented with simultaneous phakic superior bilateral rhegmatogenous retinal detachments. Treatment on the day of presentation included laser retinopexy of the inferior lattice degeneration in the left eye and bilateral intravitreal injection of 0.4 cc of 100% C3F8 gas preceded by topical anesthesia. After 48 hours, both retinas were completely reattached, and bilateral laser retinopexy was performed to the superior tears. After a review of the literature, the authors could find only two reported cases of simultaneous bilateral retinal detachments treated successfully with pneumatic retinopexy. This is not only a cost-effective procedure but also allows treatment when there is no immediate operating room availability or a when a quick referral for surgery is not possible.

    Full Text Available We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

    We report on a patient with a rare case of bilateral tension pneumothorax that occurred after acupuncture. A 69-year-old large-bodied man, who otherwise had no risk factors for spontaneous pneumothorax, presented with chest pressure, cold sweats and shortness of breath. Immediately after bilateral pneumothorax had been identified on a chest radiograph in the emergency room, his blood pressure and percutaneous oxygen saturation suddenly decreased to 78 mm Hg and 86%, respectively. We confirmed deterioration in his cardiopulmonary status and diagnosed bilateral tension pneumothorax. We punctured his chest bilaterally and inserted chest tubes for drainage. His vital signs promptly recovered. After the bilateral puncture and drainage, we learnt that he had been treated with acupuncture on his upper back. We finally diagnosed a bilateral tension pneumothorax based on the symptoms that appeared 8 h after the acupuncture. Because the patient had no risk factors for spontaneous pneumothorax, no alternative diagnosis was proposed. We recommend that patients receiving acupuncture around the chest wall must be adequately informed of the possibility of complications and expected symptoms, as a definitive diagnosis can be difficult without complete information.

  18. MODERN VIEWS ON BILATERAL BREAST CANCER

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

    Bromadiolone, often called a super-warfarin, is a potent rodenticide with long half-life. Skin and mucosal bleeding is the most common clinical manifestations of its intoxication. Bromadiolone intoxications in adults and children have been reported, but this phenomenon is rarely seen in fetuses. This paper presents a case of neonate with massive intracranial hemorrhage mediated by bromadiolone intoxication, highlighting that the bromadiolone is potentially lethal to the fetus. The male neonate presented with poor respiratory effort, decreased muscle tone, and pallor at birth. He developed generalized seizures on day 1 of life. His mother suffered from bleeding of oral mucosa and the subsequent lab screening for toxicants showed a bromadiolone level of 126 ng/mL. Laboratory tests revealed that prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT). A computed tomography (CT) of his head revealed a severe subdural hematoma, which lead to midline shift, bilateral intraventricular hemorrhage, and subarachnoid hemorrhage. Serum from cord blood was collected and screened for toxicants. The result returned with a bromadiolone level of 94 ng/mL. The neonate was treated with vitamin K, fresh-frozen plasma, and red blood cells. His parents required termination of all treatments, and the neonate unfortunately died shortly after. Through clinical experience from this case, we believe that bromadiolone can be passed down to the fetus via placenta. Neonatal intracranial hemorrhage caused by bromadiolone is rare but potentially lethal. Pregnant women should be informed of the serious side effects of bromadiolone and this poisonous reagent should be avoided in any period during pregnancy.

  3. Brain single photon emission computed tomography in neonates

    This study was designed to rate the clinical value of [ 123 I]iodoamphetamine (IMP) or [ 99m Tc] hexamethyl propylene amine oxyme (HM-PAO) brain single photon emission computed tomography (SPECT) in neonates, especially in those likely to develop cerebral palsy. The results showed that SPECT abnormalities were congruent in most cases with structural lesions demonstrated by ultrasonography. However, mild bilateral ventricular dilatation and bilateral subependymal porencephalic cysts diagnosed by ultrasound were not associated with an abnormal SPECT finding. In contrast, some cortical periventricular and sylvian lesions and all the parasagittal lesions well visualized in SPECT studies were not diagnosed by ultrasound scans. In neonates with subependymal and/or intraventricular hemorrhage the existence of a parenchymal abnormality was only diagnosed by SPECT. These results indicate that [ 123 I]IMP or [ 99m Tc]HM-PAO brain SPECT shows a potential clinical value as the neurodevelopmental outcome is clearly related to the site, the extent, and the number of cerebral lesions. Long-term clinical follow-up is, however, mandatory in order to define which SPECT abnormality is associated with neurologic deficit

    Nociceptive thresholds and supra-threshold pain ratings as well as their reduction upon local injection with lidocaine were compared between healthy subjects and patients with erythromelalgia (EM). Lidocaine (0.25, 0.50, 1.0 or 10 mg/mL) or placebo (saline) was injected intradermally in non-painful areas of the lower arm, in a randomized, double-blind manner, to test the effect on dynamic and static mechanical sensitivity, mechanical pain sensitivity, thermal thresholds and supra-threshold heat pain sensitivity. Heat pain thresholds and pain ratings to supra-threshold heat stimulation did not differ between EM-patients (n = 27) and controls (n = 25), neither did the dose-response curves for lidocaine. Only the subgroup of EM-patients with mutations in sodium channel subunits Na V 1.7, 1.8 or 1.9 (n = 8) had increased lidocaine sensitivity for supra-threshold heat stimuli, contrasting lower sensitivity to strong mechanical stimuli. This pattern was particularly clear in the two patients carrying the Na V 1.7 I848T mutations in whom lidocaine's hyperalgesic effect on mechanical pain sensitivity contrasted more effective heat analgesia. Heat pain thresholds are not sensitized in EM patients, even in those with gain-of-function mutations in Na V 1.7. Differential lidocaine sensitivity was overt only for noxious stimuli in the supra-threshold range suggesting that sensitized supra-threshold encoding is important for the clinical pain phenotype in EM in addition to lower activation threshold. Intracutaneous lidocaine dose-dependently blocked nociceptive sensations, but we did not identify EM patients with particular high lidocaine sensitivity that could have provided valuable therapeutic guidance. Acute pain thresholds and supra-threshold heat pain in controls and patients with erythromelalgia do not differ and have the same lidocaine sensitivity. Acute heat pain thresholds even in EM patients with the Na V 1.7 I848T mutation are normal and only nociceptor

    Neonatal opioid withdrawal syndrome is common due to the current opioid addiction epidemic. Infants born to women covertly abusing prescription opioids may not be identified as at risk until withdrawal signs present. Buprenorphine is a newer treatment for maternal opioid addiction and appears to result in a milder withdrawal syndrome than methadone. Initial treatment is with nonpharmacological measures including decreasing stimuli, however pharmacological treatment is commonly required. Opioid monotherapy is preferred, with phenobarbital or clonidine uncommonly needed as adjunctive therapy. Rooming-in and breastfeeding may decease the severity of withdrawal. Limited evidence is available regarding long-term effects of perinatal opioid exposure. Copyright © 2014 Elsevier Inc. All rights reserved.

    To evaluate the efficacy of tramadol, lidocaine, and a combination of tramadol with lidocaine in pain relief using periprostatic nerve block technique by guidance of transrectal ultrasound (TRUS) before the prostate biopsy (PBx). For the indication of TRUS-PBx, the patients with a prostate-specific antigen (PSA) level >4.0 ng/mL or abnormal digital examination findings were selected. The patients were randomized through random method. Group 1: patients were administered 5 mL of 2% lidocaine; group 2: patients were administered 5 mL of 25-mg tramadol; and group 3: patients were administered 5 mL of 2% lidocaine + 25-mg tramadol. The procedures were completed in 10 minutes, and a visual pain scale was administered to the patients to question the pain severity. TRUS-guided PBx was performed in 60 patients with an age range of 57-77 years (mean age, 66.2 ± 7.49 years) and a PSA range of 1-1000 ng/mL. The mean PSA level of the groups was 28.5 (±7.5), 16.1 (±5.0), and 14.9 (±2.9) ng/mL, respectively. The postprocedural pain scores by visual pain scale were 4.6 ± 1.2, 5.4 ± 1.2, and 3.6 ± 0.9 in lidocaine, tramadol, and lidocaine + tramadol groups, respectively. Periprostatic nerve block is the current golden standard method owing to pain management and comfort provided, independent of the patient age and the number of core biopsies. We suggest that tramadol may also be used in this field to achieve better pain management by improving lidocaine's effect or as an alternative to lidocaine. Copyright © 2015 Elsevier Inc.

    Prilocaine plain has a high pH and concentration (4%), which could decrease the pain of injection and increase success. The purpose of this study was to compare pain associated with anesthetic solution deposition and the degree of pulpal anesthesia obtained with the combination of prilocaine and lidocaine versus a lidocaine and lidocaine combination when used for inferior alveolar nerve blocks (IANBs). One hundred eighteen asymptomatic subjects were randomly given a combination of 1 cartridge of 4% prilocaine plain plus 1 cartridge of 2% lidocaine with 1:100,000 epinephrine or a combination of 2 cartridges of 2% lidocaine with 1:100,000 epinephrine for the IANB at 2 separate appointments. Subjects rated the pain associated with anesthetic solution deposition of injection. Mandibular teeth were tested with an electric pulp tester every 4 minutes for 57 minutes. Anesthesia was considered successful when 2 consecutive 80 readings were obtained within 17 minutes and the 80 reading was continuously sustained for 57 minutes. Comparisons for anesthetic success were analyzed using the exact McNemar test, and pain ratings associated with anesthetic solution deposition were analyzed using multiple Wilcoxon matched pairs signed rank tests; both were adjusted using the step-down Bonferroni method of Holm. Four percent prilocaine plain was significantly less painful upon anesthetic solution deposition. Pulpal anesthetic success was not significantly different between the 2 combinations. The combination of 4% prilocaine plain plus 2% lidocaine with 1:100,000 epinephrine did not increase pulpal anesthetic success for IANBs compared with a combination of 2 cartridges of 2% lidocaine with 1:100,000 epinephrine. Pain associated with anesthetic solution deposition from the first cartridge of 4% prilocaine plain was significantly less when compared with the first cartridge of 2% lidocaine with 1:100,000 epinephrine.

    Full Text Available The aims of this study were to evaluate the isoflurane sparing and clinical effects of a constant rate infusion of morphine – lidocaine – ketamine (MLK in healthy sheep undergoing experimental gastrointestinal surgery. Twelve adult female sheep (Texel breed were used, weighing 36.5 ± 8.1 kg. The sheep were anesthetized for the implantation of duodenal cannulas. The sheep were premedicated with 0.3 mg kg-1 intramuscular (IM morphine and 20 ?g kg-1 intravenous (IV detomidine. After premedication, anesthesia was induced using 5 mg kg-1 ketamine and 0.5 mg kg-1 diazepam IV and maintained using isoflurane in 100% oxygen. After the induction of anesthesia, the animals were allocated into two groups (each n=6; the GMLK (MLK group – 10 mg morphine, 150 mg lidocaine, 30 mg de ketamine were added in 500 mL saline received a 10 mL kg-1h-1 MLK infusion during the maintenance of anesthesia, and GCON (control group received 10 mL kg-1h-1 of 0.9% sodium chloride. The animals were mechanically ventilated. Cardiopulmonary variables and end-tidal isoflurane concentration (FE´Iso were measured at baseline (immediately before the surgery and 15, 30 and 45 minutes after initiation of surgery. In GMLK, there was a decrease in the FE´Iso at 15, 30 and 45 minutes, a reduction of up to 75.6% during the surgery. The HR was lower in GMLK compared with GCON at 30 minutes, and the MAP was at during baseline in GCON compared with GMLK. The standing time was less in GMLK than in GCON. The use of intravenous MLK was demonstrated to offer great efficiency as part of a balanced anesthesia protocol in sheep, with a 75.6% reduction in the need for isoflurane, providing stability of the cardiovascular parameters and blood gases with a shortened recovery period.

    Major defects in neonatal skin have serious consequences for the health of the baby, but fortunately these are very rare. Early diagnosis of the genodermatoses can be life-saving. Birthmarks, also known as naevi, are usually first noted in neonates, and can be very alarming for parents. A variety of infections can.

    Bilateral agenesis of the anterior cruciate ligament (ACL) is extremely rare. We describe a 13-year-old girl who presented with bilateral knee pain without history of trauma; she has two family members with knee instability. Magnetic resonance imaging showed bilateral absence of the ACL, and medial posterior horn meniscal tears. Bilateral arthroscopic partial meniscectomy and anterior cruciate ligament reconstruction was performed. (orig.)

    Healy, Patricia; Fallon, Anne

    This article reviews the origins and evolution of neonatology and considers the role of the neonatal nurse within this specialty. Neonatal nurses are a vital part of the neonatal team that provides care for sick babies. The nursing care required by sick babies and their families on a neonatal unit can be variable and complex. The past century has seen significant changes in the role of the neonatal nurse. This has come about through dramatic technological developments on neonatal units, an increased understanding of neonatal physiology and pathology, changes in the education of neonatal nurses, and active and ongoing clinical research within the specialty. The resulting significant advances in neonatal care, including that provided by neonatal nurses, have made a crucial and steadfast contribution to marked improvements in neonatal outcomes.

    During fetal development, the hippocampal structures fold around the hippocampal sulcus into the temporal lobe. According to the literature, this inversion should be completed at gestation week (GW) 21. Thereafter, the hippocampal shape should resemble the adult shape. However, incomplete hippocampal inversion (IHI) is found in 19% of the common population. The aim of this study was to study fetal hippocampal development by examining neonates born preterm. We analyzed cranial ultrasound examinations, performed as a part of the routine assessment of all preterm infants, over a 3-year period and excluded the infants with brain pathology. The final material consisted of 158 children born <35 GW. A rounded form (the ratio between the horizontal and vertical diameters of the hippocampal body {<=}1) in coronal slices was considered the sign of IHI. The age at examination was 23-24 GW in 24 neonates, 25-28 GW in 70 neonates, and 29-36 GW in 64 neonates. IHI was found in 50%, 24%, and 14%, respectively. The difference between the neonates <25 GW and {>=}25 GW was statistically highly significant (p < 0.001). The frequency of bilateral IHI was highest in the youngest age group. In the other groups, the left-sided IHI was the most common. In about 50% of the neonates, hippocampal inversion is not completed up to GW 24; but from 25 GW onwards, the frequency and laterality of IHI is similar to that in the adult population. (orig.)

    Plain radiographs for infants in the neonatal intensive care unit are obtained using the portable X-ray equipment in order to evaluate the neonatal lungs and also to check the position of the tubes and catheters used for monitoring critically-ill neonates. Neonatal respiratory distress is caused by a variety of medical or surgical disease conditions. Clinical information about the gestational week, respiratory symptoms, and any events during delivery is essential for interpretation of the neonatal chest radiographs. Awareness of common chest abnormality in the prematurely born or term babies is also very important for chest evaluation in the newborn. Furthermore, knowledge about complications such as air leaks and bronchopulmonary dysplasia following treatment are required to accurately inform the clinicians. The purpose of this article was to briefly review radiographic findings of chest diseases in newborns that are relatively common in daily practice.

    In Brazil electricity is traded through three segments: the spot market that balances offer and demand, with prices calculated by a cost-based computational model; the regulated market , where prices are settled in public auctions, and the free market for bilateral contracts. As spot and regulated market prices are public information, a seller is able to calculate his opportunity price to trade a bilateral contract in the free market by using the non-arbitrage principle. Thus, the seller searches the price of a bilateral contract in the free market that balances his/her revenues with the value expected in case it were negotiated in the regulated and the spot market. Besides the expected revenue, the seller may also consider the CVaR to measure the risk of her/his bilateral contract in the free market. So this paper develops a binomial lattice approach to price bilateral contracts in the free market, considering the seller's opportunity of negotiations in both regulated and spot markets, and measuring the contract risk directly.

    Only a few reports have discussed the detailed clinical symptoms and pathogenesis of bilateral thalamic infarction. The thalamus is composed of different functional nuclei and supplied by vessels containing several variations from the main arteries, leading to difficulty in the precise evaluation of bilateral thalamic infarction. In the present study, we assessed the prognosis of bilateral thalamic infarction based on the distribution of stroke lesions. From among the consecutive ischemic stroke patients admitted to hospital between April 2001 and March 2005, cases of acute bilateral thalamic infarction were selected for this study (n=9; 65.1±13.6 y.o.). The stroke lesions and vascular abnormalities were investigated by magnetic resonance imaging and magnetic resonance angiography on admission. Outcome was evaluated from the modified Rankin scale (mRS) at discharge. Good outcome patients (mRS 0-2; n=5) showed memory disturbance, cognitive impairment and hypersomnia. On the other hand, quadriplegia, oculomotor disturbance and bulbar palsy were observed in the poor outcome patients (mRS≥4; n=4). The critical features of a poor outcome were the age at onset (72.0±15.3 vs. 58.2±11.9 y.o.), inclusion of brainstem lesions and total occlusion of the basilar artery. In conclusion, older age at onset and/or basilar artery occlusion may be critical factors for predicting a poor outcome in bilateral thalamic infarction cases. (author)

    Although local anesthesia is commonly applied for pain relief, there are several issues such as its short duration of action and low effectiveness at the areas of inflammation due to the acidic pH. The presence of excessive amount of reactive oxygen species (ROS) is known to induce inflammation and aggravate pain. To resolve these issues, we developed a redox-active injectable gel (RIG) with ROS-scavenging activity. RIG was prepared by mixing polyamine-b-poly(ethylene glycol)-b-polyamine with nitroxide radical moieties as side chains on the polyamine segments (PMNT-b-PEG-b-PMNT) with a polyanion, which formed a flower-type micelle via electrostatic complexation. Lidocaine could be stably incorporated in its core. When the temperature of the solution was increased to 37°C, the PIC-type flower micelle transformed to gel. The continuous release of lidocaine from the gel was observed for more than three days, without remarkable initial burst, which is probably owing to the stable entrapment of lidocaine in the PIC core of the gel. We evaluated the analgesic effect of RIG in carrageenan-induced arthritis mouse model. Results showed that lidocaine-loaded RIG has stronger and longer analgesic effect when administered in inflamed areas. In contrast, while the use of non-complexed lidocaine did not show analgesic effect one day after its administration. Note that no effect was observed when PIC-type flower micelle without ROS-scavenging ability was used. These findings suggest that local anesthetic-loaded RIG can effectively reduce the number of injection times and limit the side effects associated with the use of anti-inflammatory drugs for postoperative pain management. 1. We have been working on nanomaterials, which effectively eliminate ROS, avoiding dysfunction of mitochondria in healthy cells. 2. We designed redox injectable gel using polyion complexed flower type micelle, which can eliminates ROS locally. 3. We could prepare local anesthesia-loaded redox injectable

    2014-02-01

    Neonatal hypoglycemia is one of the most common biochemical abnormalities encountered in the newborn. However, controversy remains surrounding its definition and management especially in asymptomatic patients. New information has been published that describes the incidence and timing of low glucose concentrations in the groups most at risk for asymptomatic neonatal hypoglycemia. Furthermore, one large prospective study failed to find an association between repetitive low glucose concentrations and poor neurodevelopmental outcomes in preterm infants. But hypoglycemia due to hyperinsulinism, especially genetic causes, continued to be associated with brain injury. New advances were made in the diagnosis and management of hyperinsulinism, including acquired hyperinsulinism in small for gestational age infants and others. Continuous glucose monitoring remains an attractive strategy for future research in this area. The fundamental question of how best to manage asymptomatic newborns with low glucose concentrations remains unanswered. Balancing the risks of overtreating newborns with low glucose concentrations who are undergoing a normal transition following birth against the risks of undertreating those in whom low glucose concentrations are pathological, dangerous, and/or a harbinger of serious metabolic disease remains a challenge.

  1. Neonatal status of twins

    Full Text Available Multiple pregnancy is a pregnancy where more than one fetus develops simultaneously in the womb, as a result of the ovulation and fertilization of more than one egg. It is relatively rare in humans and represents the rest of the phylogenetic stages. The most common are twins and they indicate the development of two fetuses in the womb. The frequency of twin pregnancies is about 1%. Multiple pregnancies belong to a group of high-risk pregnancies because of the many complications that occur during the pregnancy: higher number of premature deliveries, bleeding, early neonatal complications and higher perinatal morbidity and mortality. Such pregnancies and infants require greater supervision and monitoring. The aim of this study was to determine the percentage of baby twins born at the maternity ward of the General Hospital in Prokuplje and their morbidity and mortality. Data on the total number of deliveries, number of twins, parity and maternal age, gestational age, body weight of twins, method of delivery, Apgar score and perinatal mortality were collected and statistically analyzed by means of retrospective analysis of operative birth and neonatal protocol for 6 years (2005 of 2010. Out of 4527 mothers who gave birth 43 were pairs of twins, or 0.95% of women gave birth to twins. These babies are more likely born by Caesarean section, but delivered with slightly lower birth weight.

    Neonatal sigmoid volvulus is a rare entity. It is associated with Hirschsprung's disease. Presentation is acute abdominal distention, vomiting and obstipation. Abdominal radiograph will show the "coffee bean" sign, but this is frequently missed and the diagnosis requires a high index of suspicion. Treatment options include contrast enema, colonoscopy or laparotomy, depending on the condition of the baby and local availability. During the last 6years, 6 infants with sigmoid volvulus were treated in our department. Four presented during the first 48h since birth, and 2 presented at the age of 2 and 7weeks of age. One child was operated and 5 had primary contrast enema with radiologic de-volvulus. Rectal biopsy was performed in all cases; three children had Hirschsprung's disease. Those with normal biopsies responded well to rectal washouts. Two patients had early one stage transanal pullthrough and one had 2 further occasions of sigmoid volvulus prior to definitive surgery. All three recovered with an uneventful course. Neonatal sigmoid volvulus requires a high level of suspicion. Contrast enema is efficient for primary de-volvulus. Rectal biopsy should be performed and if positive for Hirschsprung's disease, surgery should be performed sooner rather than later. Copyright © 2016 Elsevier Inc. All rights reserved.

The main result of the study is that Danish bilateral aid has a positive and statistically significant impact on Danish exports to the recipient countries. Bilateral development assistance may affect exports through several channels. Three of the main channels are direct aid tying......; increasing recipient income where higher income leads to higher imports, and decreased trade costs, say due to improved information about cultural and administrative customs and practices. Thus, as for preferential trade arrangements, bilateral aid has two potential economic effects; trade creation working...

  4. Noise reduction with complex bilateral filter.

    Matsumoto, Mitsuharu

    2017-12-01

    This study introduces a noise reduction technique that uses a complex bilateral filter. A bilateral filter is a nonlinear filter originally developed for images that can reduce noise while preserving edge information. It is an attractive filter and has been used in many applications in image processing. When it is applied to an acoustical signal, small-amplitude noise is reduced while the speech signal is preserved. However, a bilateral filter cannot handle noise with relatively large amplitudes owing to its innate characteristics. In this study, the noisy signal is transformed into the time-frequency domain and the filter is improved to handle complex spectra. The high-amplitude noise is reduced in the time-frequency domain via the proposed filter. The features and the potential of the proposed filter are also confirmed through experiments.

    To study the natural history and retinal findings associated with the intraretinal and subretinal fibrovascular tissues that develop in the late phases of bilateral juxtafoveal telangiectasis. The records of 10 patients (11 eyes) with bilateral juxtafoveal telangiectasis who developed these fibrovascular tissues were examined. Throughout the follow-up period (average 44 months), only 2 eyes (18%) lost 2 or more lines of vision; the final visual acuities were similar for the eyes both with and without fibrovascular tissues. Sixty-four percent of fibrovascular tissues showed little to no growth. Eyes with fibrovascular tissue commonly had retinal pigment epithelial hyperplasia (72%), draining retinal venules (82%), and retinal vascular distortion (64%). Fibrovascular tissues of bilateral juxtafoveal telangiectasis have little proliferative potential and minimal effects on visual acuity. Nevertheless, these fibrovascular tissues do remodel over time, leading to retinal vascular distortion. Given these benign findings, the role of laser photocoagulation treatment of these tissues is questionable.

    To describe the excellent outcome of surgery for bilateral giant retinal tears (GRTs) with better options of endotamponade. This is a case report of a 62-year-old man who presented with bilateral GRTs and associated retinal detachment. The tear in the right eye was supero-temporal and silicone oil was used as an endotamponade. The tear in the left eye was infero-temporal and perfluorocarbon liquid was used as an endotamponade. The outcome at 6 months after surgery was excellent with visual acuities of 6/6 in both eyes. Improved availability of endotamponade agents allows repair of bilateral GRTs to be done at the same time, with good surgical outcomes.

    To our knowledge, bilateral supernumerary kidney is a very rare renal abnormality and there are five cases presented in the literature. It is difficult to diagnose supernumerary kidney and clinicians have not detected most cases preoperatively. Laboratory and imaging studies were acquired and carefully examined. The normal laboratory tests were found. Emergency ultrasonography was performed and they revealed no signs of parenchymal abnormality in both kidneys. Serial imaging study including enhanced computed tomography (CT) was performed. An imaging study identified bilateral supernumerary kidney with expanded collecting systems. On each side, significant rotation anomaly was found. In addition, there were two different renal arteries originating from the aorta. This report presents radiological determinations of supernumerary kidney bilaterally in a young man. We think that CT commonly appears to be enough for the diagnosis of supernumerary kidneys

    2016-04-01

    Full Text Available Bilateral acute iris transillumination (BAIT is a recently defined disease characterized with bilateral acute, severe pigment dispersion of iris and pupil sphincter paralysis. The etiopathogenesis of the disease is unknown, but antibiotics such as moxifloxacin, clarithromycin, viral infections, and fumigation therapies were considered as probable etiologic factors. A 33-year-old female was referred to our clinic for acute iridocyclitis refractory to azathioprine, colchicum and corticosteroid treatments. Ophthalmic examination revealed bilateral pigment dispersion, significant iris transillumination, heavy pigment deposition in iridocorneal angle, and elevated intraocular pressure. Upon systemic evaluation she was found to have bacterial urinary tract infection. BAIT is an important cause of pigment dispersion and clinicians must be vigilant for this condition to avoid unnecessary diagnostic tests and treatment.

    Clear cell sarcoma of the kidney (CCSK) accounts for 2-5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone metastasis; while other present only with bilateral masses with no evident distant metastasis. Both patients received aggressive neo-adjuvant chemotherapy to decrease tumor size. One patient completed his designated treatment and initially showed complete remission (CR); eventually suffering from relapse. The other patient’s tumor progressed during the course of chemotherapy. Both cases manifested brain dissemination at the time of relapse or progression. This emphasizes the importance of staging stratification in CCSK. This also illustrates CCSK’s ability to metastasize to bone and other sites including the brain (a primary relapse site in our cases)

    Currently, no consistent evidence-based guidelines for the management of synchronous bilateral breast cancer (SBBC) exist and it is uncertain how presenting with SBBC affects patients' prognosis. We conducted a review of studies analyzing the association between SBBC and prognosis. The studies...... that reported adjusted effect measures were included in meta-analyses of effect of bilaterality on breast cancer mortality. From 57 initially identified records 17 studies from 11 different countries including 8,050 SBBC patients were included. The quality of the studies varied but was generally low with small...... sample sizes, and lack of consistent, detailed histo-pathological information. When doing meta-analysis on the subgroup of studies that provided adjusted effect estimates on breast cancer mortality (nine studies including 3,631 SBBC cases), we found that bilaterality in itself had a negative impact...

    2018-05-01

    Bilateral true vocal fold paralysis is rarely attributable to inflammatory diseases. Sarcoidosis is a rare but important etiology of bilateral true vocal fold paralysis by compressive lymphadenopathy, granulomatous infiltration, and neural involvement. We describe the first reported case of sarcoidosis presenting as bilateral vocal fold immobility caused by direct fixation by granulomatous infiltration severe enough to necessitate tracheostomy insertion. In addition, we discuss the presentation, the pathophysiology, and the treatment of this disease with a review of the literature of previously reported cases of sarcoidosis-related vocal fold immobility. Sarcoidosis should therefore be an important consideration for the otolaryngologist's differential diagnosis of true vocal fold immobility. Copyright © 2018 The Voice Foundation.

    2018-04-13

    In evaluating patients sustaining bilateral isolated internal orbital fractures, the authors have observed both similar fracture locations and also similar expansion of orbital volumes. In this study, we aim to investigate if there is a propensity for the 2 orbits to fracture in symmetrically similar patterns when sustaining similar trauma. A retrospective chart review was performed studying all cases at our institution of bilateral isolated internal orbital fractures involving the medial wall and/or the floor at the time of presentation. The similarity of the bilateral fracture locations was evaluated using the Fisher's exact test. The bilateral expanded orbital volumes were analyzed using the Wilcoxon signed-rank test to assess for orbital volume similarity. Twenty-four patients with bilateral internal orbital fractures were analyzed for fracture location similarity. Seventeen patients (70.8%) had 100% concordance in the orbital subregion fractured, and the association between the right and the left orbital fracture subregion locations was statistically significant (P < 0.0001). Fifteen patients were analyzed for orbital volume similarity. The average orbital cavity volume was 31.2 ± 3.8 cm on the right and 32.0 ± 3.7 cm on the left. There was a statistically significant difference between right and left orbital cavity volumes (P = 0.0026). The data from this study suggest that an individual who suffers isolated bilateral internal orbital fractures has a statistically significant similarity in the location of their orbital fractures. However, there does not appear to be statistically significant similarity in the expansion of the orbital volumes in these patients.

    Outcome assessment after double level tibial lengthening in patients with dwarfism. Fourteen patients with dwarfism were analyzed after bilateral simultaneous double level tibial lengthening. Average age was 15.1 years. Average lengthening was 13.5 cm. The two levels were lengthened by an average of 7.5 cm proximally and 6.0 cm distally. Concomitant deformities were also addressed during lengthening. External fixation treatment time averaged 8.8 months. Healing index averaged 0.7 months/cm. Bilateral tibial lengthening for dwarfism is difficult, but the results are usually quite gratifying.

    Full Text Available Spontaneous tegmen tympani defects are rare with even rarer bilateral cases. The symptoms are nonspecific; hence, a high index of suspicion is required to prevent serious intracranial complications. We present a case of spontaneous bilateral tegmen tympani defects with associated meningoencephalocoeles in a 54-year-old male who presented with the signs and symptoms of severe meningitis. After careful workup which included a lumbar puncture, CT and MRI scans, both defects were repaired using a middle fossa approach. The patient made an uneventful recovery with complete cessation of otorrhoea and improvement in his hearing.

    The stability of diphenhydramine hydrochloride (from an elixir) and lidocaine hydrochloride (from a viscous solution) in a mixture (1:1) was studied using a stability-indicating high-peformance liquid chromatographic assay method. The concentrations of the drugs were related directly to peak heights and the percent relative standard deviations based on five injections were 1.4 for diphenhydramine and 1.3 for lidocaine. The products of hydrolysis from the both the drugs and a number of excipients present in the dosage forms did not interfere with the developed assay procedure. The mixture was stable for at least 21 days when stored in amber-colored bottles at room temperature. The pH value of the mixture remained constant, and the physical appearance did not change during the study period.

Despite this fact and in contrast to tailored perfusion equipment, incubators or ventilators for neonates, we still commonly use drug formulations initially developed for adults. We would like to make the point that drug formulations given to neonates need to be tailored for this age group. Besides the obvious need to search for active compounds that take the pathophysiology of the newborn into account, this includes the dosage and formulation. The dosage or concentration should facilitate the administration of low amounts and be flexible since clearance is lower in neonates with additional extensive between-individual variability. Formulations need to be tailored for dosage variability in the low ranges and also to the clinical characteristics of neonates. A specific focus of interest during neonatal drug development therefore is a need to quantify and limit excipient exposure based on the available knowledge of their safety or toxicity. Until such tailored vials and formulations become available, compounding practices for drug formulations in neonates should be evaluated to guarantee the correct dosing, product stability and safety.

    Full text: Hypoxic-Ischemic insults in the brain of neonates constitute major cause of morbidity and mortality. A wide range of motor, sensory, and cognitive disabilities are observed in this population spanning from slight motor deficits, school difficulties and behavioral problems up to cerebral palsy and mental retardation. Pathologically involved areas characterized by high metabolic demands and therefore with enhanced vulnerability to any reduction or cessation of energy and oxygen supply. Watershed areas of the brain (vascular end zones and vascular border zones) are predominately affected in any adverse event. Radiologic and pathologic appearance of these lesions depends both on the severity of the insult and the maturity of the brain. The dominant pathology observed in preterm neonates is white matter lesions. There are three basic patterns of brain destruction in this population. Periventricular leukomalacia (PVL focal fPVL, diffuse dPVL), germinal matrix haemorrhage (GMH) associated with intraventricular haemorrhage (IVH), and parenchymal haemorrhage (PH). fPVL is characterized by focal necrosis of all cellular elements in the periventricular white matter, resulting in the formation of cysts, and dPVL is characterized by diffuse destruction of the premyelinating oligodendrocytes (pre-OLs) the precursors of mature oligodendroglia cells responsible for the formation of myelin in a later stage. GMH is located beneath germinal matrix layer surrounding the lateral ventricles and can extend into the ventricular system resulting thus to IVH. Finally, PH is located within the parenchyma adjacent to the ventricles and is believed to represent haemorrhagic infarcts following venous drainage compromise. In term or near-term neonates, the top-ographic pattern of injuries involves mainly gray matter structures. Most frequent predilection sites include the cerebral cortex (paracentral lobule, Rolandic area, visual cortex and hippocampus), basal ganglia, thalamus, and

    The purpose of these 2 prospective, randomized, single-blind studies was to determine the anesthetic efficacy of lidocaine with epinephrine compared with a combination lidocaine with epinephrine plus 0.5 mol/L mannitol for inferior alveolar nerve (IAN) blocks in patients experiencing symptomatic irreversible pulpitis. In study one, 55 emergency patients randomly received IAN blocks by using a 3.18-mL formulation containing 63.6 mg of lidocaine with 31.8 μg epinephrine or a 5-mL formulation containing 63.6 mg of lidocaine with 31.8 μg epinephrine (3.18 mL) plus 1.82 mL of 0.5 mol/L mannitol. In study two, 51 emergency patients randomly received IAN blocks by using a 1.9-mL formulation containing 76.4 mg of lidocaine with 36 μg epinephrine or a 3-mL formulation containing 76.4 mg of lidocaine with 36 μg epinephrine (1.9 mL) plus 1.1 mL of 0.5 mol/L mannitol. Endodontic access was begun 15 minutes after the IAN block, and all patients had profound lip numbness. Success was defined as no or mild pain (visual analogue scale recordings) on endodontic access or instrumentation. The 1.9 mL of lidocaine (76.4 mg) with epinephrine plus 0.5 mol/L mannitol had a significantly (P = .04) better success rate of 39% when compared with the lidocaine formulation without mannitol (13% success rate). For mandibular posterior teeth in patients with symptomatic irreversible pulpitis, the addition of 0.5 mol/L mannitol to 1.9 mL of lidocaine (76.4 mg) with epinephrine resulted in a statistically higher success rate. However, the combination lidocaine/mannitol formulation would not result in predictable pulpal anesthesia. Copyright © 2012 American Association of Endodontists. Published by Elsevier Inc.

    Ultrasound guidance facilitates precise needle and injectate placement, increasing axillary block success rates, reducing onset times, and permitting local anesthetic dose reduction. The minimum effective volume of local anesthetic in ultrasound-guided axillary brachial plexus block is unknown. The authors performed a study to estimate the minimum effective anesthetic volume of 2% lidocaine with 1:200,000 epinephrine (2% LidoEpi) in ultrasound-guided axillary brachial plexus block.

    Methemoglobinemia is a relatively rare, but potentially life-threating medical condition, which may be induced by application of topical anaesthetic agents commonly used during endoscopic procedure. The aim of our study was to assess the influence of lidocaine used prior to transesophageal echocardiography (TEE) on the blood level of methemoglobin in vivo. Additionally we attempted to establish the occurrence rate of clinically evident lidocaine-induced methemoglobinemia on the basis of data collected in our institution. We retrospectively analyzed patient records from 3,354 TEEs performed in our echocardiographic laboratory over the course of 13 years in search for clinically evident methemoglobinemia cases. Additionally, 18 consecutive patients referred for TEE were included in the prospective part of our analysis. Blood samples were tested before and 60 min after pre-TEE lidocaine anesthesia application. Information concerning concomitant conditions and pharmacotherapy were also obtained. In 3,354 patients who underwent TEE in our institution no cases of clinically evident methemoglobinemia occurred. In the prospective part of the study, none of 18 patients [16 (89 %) men, mean age 63 ± 13] was diagnosed with either clinical symptoms of methemoglobinemia or exceeded normal blood concentration of methemoglobin. Initial mean methemoglobin level was 0.5 ± 0.1 % with mild, statistically (but not clinically) significant rise to 0.6 ± 0.1 % after 60 min (p = 0.02). Among the analyzed factors only the relation between the proton pump inhibitors intake and methemoglobin blood level rise was identified as statistically relevant (p = 0.03). In adults, pre-TEE lidocaine anesthesia with recommended dosage results in significant increase in methemoglobin blood level, which however does not exceed normal values and does not result in clinically evident methemoglobinemia.

    Full Text Available Objectives: There are a number of potential advantages to performing hysteroscopy in an outpatient setting. However, the ideal approach, using local uterine anesthesia or rectal non-steroidal anti-inflammatory drugs, has not been determined. Our objective was to compare the efficacy of intrauterine lidocaine instillation with rectal diclofenac for pain relief during diagnostic hysteroscopy. Methods: We conducted a double-blind randomized controlled trial on 70 nulliparous women with primary infertility undergoing diagnostic hysteroscopy. Subjects were assigned into one of two groups to receive either 100mg of rectal diclofenac or 5mL of 2% intrauterine lidocaine. The intensity of pain was measured by a numeric rating scale 0–10. Pain scoring was performed during insertion of the hysteroscope, during visualization of the intrauterine cavity, and during extrusion of the hysteroscope. Results: There were no statistically significant differences between the groups with regard to the mean pain score during intrauterine visualization (p=0.500. The mean pain score was significantly lower during insertion and extrusion of the hysteroscope in the diclofenac group (p=0.001 and p=0.030, respectively. Nine patients in the lidocaine group and five patients in diclofenac group needed supplementary intravenous propofol injection for sedation (p=0.060. Conclusions: Rectal diclofenac appears to be more effective than intrauterine lidocaine in reducing pain during insertion and extrusion of hysteroscope, but there are no significant statistical and clinical differences between the two methods with regard to the mean pain score during intrauterine inspection.

    1. The present study evaluates the necessity of the ventroposterior medial thalamic nucleus (VPM) for discrimination of the intensity of noxious heating, innocuous cooling, and innocuous tactile (airpuff) stimulation of the maxillary skin. 2. Two rhesus monkeys were trained to detect small differences (Lidocaine hydrochloride (2%) was microinjected into regions of thalamus where single-unit recordings had identified neuronal responses to the noxious heating and/or cooling stimuli. The effectiveness of the anesthetic blockade was monitored by multiunit recordings using microelectrodes positioned 1-3 mm from the orifice of the injection cannula. The monkey's ability to detect near-threshold changes in stimulus intensity was compared before and after each injection. 3. During six experimental sessions, single injections of 1-4 microliters lidocaine near the dorsomedial border of VPM did not significantly alter the monkey's ability to detect small changes in the intensity of noxious heat, cool, airpuff, or visual stimuli despite neurophysiological evidence that spontaneous neuronal activity was blocked within parts of VPM. 4. During three experiments, dual simultaneous microinjections of lidocaine (delivered through 2 microcannulae separated by approximately 1 mm) resulted in profound deficits in noxious heat discrimination, with lesser deficits in cool and airpuff discrimination; visual discrimination was never altered. Monitoring of adjacent microelectrodes revealed that although activity ventral to the injection sites was blocked, activity in medial thalamic nuclei, implicated in nociceptive processing, was probably not altered by these injections. 5. These data suggest that VPM is important for the perception of noxious and innocuous thermal stimuli as well as for the perception of tactile stimuli. However, considering the ineffectiveness of small single microinjections of lidocaine, it appears that some critical proportion of VPM must be inactivated to disrupt

    During the early mixed dentition period, the location of the deciduous maxillary second molar results in ineffectiveness of the infiltration technique in this area. In such cases, administration of posterior superior alveolar (PSA) nerve block is recommended; however, such a technique has some complications. The present study was undertaken to compare the effects of buccal infiltration of 4% Articaine and PSA technique with 2% Lidocaine on the success of anesthesia of maxillary deciduous second molars in 6 to 9-year old children. In the present double-blind randomized clinical trial, 56 children aged 6-9 years requiring vital pulp therapy of deciduous maxillary second molar were included. In group 1, 4% Articaine was injected using a buccal infiltration technique. In group 2, 2% Lidocaine was injected using the PSA nerve block technique. After 10 min, the caries was removed and access cavity preparation was instituted. The patients were asked to report the presence or absence of pain during the procedure. Therefore, the existence of pain was measured by the patient's self-report. Data were analyzed with descriptive statistical methods and the chi -squared test. Pain was reported by 6 (21.4%) and 9 (32.1%) subjects in the Articaine and Lidocaine groups, respectively. Chi -squared test did not reveal any significant differences between the two groups ( P =0.54). Under the limitations of the present study, there was no significant differences between the results of Articaine buccal infiltration and Lidocaine PSA technique, so Articaine buccal infiltration can be used as a substitute for the PSA technique.

    A perioperative intravenous lidocaine infusion has been reported to decrease postoperative pain. The goal of this study was to evaluate the effectiveness of intravenous lidocaine in reducing postoperative pain for laparoscopic colectomy patients. Fifty-five patients scheduled for an elective laparoscopic colectomy were randomly assigned to 2 groups. Group L received an intravenous bolus injection of lidocaine 1.5 mg/kg before intubation, followed by 2 mg/kg/h continuous infusion during the operation. Group C received the same dosage of saline at the same time. Postoperative pain was assessed at 2, 4, 8, 12, 24, and 48 hours after surgery by using the visual analog scale (VAS). Fentanyl consumption by patient-controlled plus investigator-controlled rescue administration and the total number of button pushes were measured at 2, 4, 8, 12, 24, and 48 hours after surgery. In addition, C-reactive protein (CRP) levels were checked on the operation day and postoperative days 1, 2, 3, and 5. VAS scores were significantly lower in group L than group C until 24 hours after surgery. Fentanyl consumption was lower in group L than group C until 12 hours after surgery. Moreover, additional fentanyl injections and the total number of button pushes appeared to be lower in group L than group C (P < 0.05). The CRP level tended to be lower in group L than group C, especially on postoperative day1 and 2 and appeared to be statistically significant. The satisfaction score was higher in group L than group C (P = 0.024). Intravenous lidocaine infusion during an operation reduces pain after a laparoscopic colectomy. PMID:25785316

    Full Text Available Background: Different additives have been used to prolong brachial plexus block. We performed a prospective, randomised, double-blind study to evaluate the effect of dexamethasone added to lidocaine on the onset and duration of supraclavicular brachial plexus block as this is the most common type of brachial block performed in our institute. Methods: Sixty American Society of Anaesthesiologist′s physical status I and II patients undergoing elective hand, forearm and elbow surgery under brachial plexus block were randomly allocated to receive either 1.5% lidocaine (7 mg/kg with adrenaline (1:200,000 and 2 ml of normal saline (group C, n=30 or 1.5% lidocaine (7 mg/kg with adrenaline (1:200,000 and 2 ml of dexamethasone (8 mg (group D, n=30. The block was performed using a nerve stimulator. Onset and duration of sensory and motor blockade were assessed. The sensory and motor blockade of radial, median, ulnar and musculocutaneous nerves were evaluated and recorded at 5, 10, 20, 120 min, and at every 30 min thereafter. Results: Two patients were excluded from the study because of block failure. The onset of sensory and motor blockade (13.4±2.8 vs. 16.0±2.3 min and 16.0±2.7 vs. 18.7±2.8 min, respectively were significantly more rapid in the dexamethasone group than in the control group ( P=0.001. The duration of sensory and motor blockade (326±58.6 vs. 159±20.1 and 290.6±52.7 vs. 135.5±20.3 min, respectively were significantly longer in the dexamethasone group than in the control group ( P=0.001. Conclusion: Addition of dexamethasone to 1.5% lidocaine with adrenaline in supraclavicular brachial plexus block speeds the onset and prolongs the duration of sensory and motor blockade.

    Lip augmentation with hyaluronic acid fillers is an established procedure. As monophasic polydensified hyaluronic acid products with variable density CPM-HAL1 (Belotero® Balance Lidocaine) and CPM-HAL2 (Belotero® Intense Lidocaine) are qualified for beautification and particularly natural-looking rejuvenation, respectively. Assessment of handling and outcome of lip augmentation using the lidocaine-containing hyaluronic acid fillers CPM-HAL1 and CPM-HAL2. Data from patients who received lip augmentation by means of bautification and/or rejuvenation using CPM-HAL1 and/or CPM-HAL2 were documented. Observation period was 4 months, with assessment of natural outcome, evenness, handling, fluidity, distribution, malleability, tolerability, as well as patient satisfaction and pain. In total, 146 patients from 21 German centres participated. Physicians rated natural outcome and evenness as good or very good for > 95 % of patients. Handling, fluidity, distribution and malleability were assessed for both fillers as good or very good in > 91 % of patients. At every evaluation point, more than 93 % of patients were very or very much satisfied with the product. A total of 125 patients (85.6 %) experienced transient injection-related side effects. Pain intensity during the procedure was mild (2.72 ± 1.72 on the 0-10 pain assessment scale) and abated markedly within 30 min (0.42 ± 0.57). Lip augmentation with hyaluronic acid fillers produced a long-term cosmetic result. Due to the lidocaine content, procedural pain was low and transient. Accordingly, a high degree of patient satisfaction was achieved that was maintained throughout the observation period.

    The association between pediatric cancer and congenital abnormalities is well known but, there is no exclusive data on the neonatal period and the underlying etiopathogenic mechanisms are unknown. First, to analyze the frequency of neonatal tumours associated with congenital abnormalities; and second, to comment on the likely etiopathogenic hypotheses of a relationship between neonatal tumours and congenital abnormalities. Historical series of neonatal tumours from La Fe University Children's Hospital in Valencia (Spain), from January 1990 to December 1999. Histological varieties of neonatal tumours and associated congenital abnormalities were described. A systematic review of the last 25 years was carried out using Medline, Cancerlit, Index Citation Science and Embase. The search profile used was the combination of "neonatal/congenital-tumors/cancer/neoplasms" and "congenital malformations/birth defects". 72 neonatal tumours were identified (2.8% of all pediatric cancers diagnosed in our hospital) and in 15 cases (20.8%) there was some associated malformation, disease or syndrome. The association between congenital abnormalities and neonatal tumours were: a) angiomas in three patients: two patients with congenital heart disease with a choanal stenosis, laryngomalacia; b) neuroblastomas in two patients: horseshoe kidney with vertebral anomalies and other with congenital heart disease; c) teratomas in two patients: one with cleft palate with vertebral anomalies and other with metatarsal varus; d) one tumour of the central nervous system with Bochdaleck hernia; e) heart tumours in four patients with tuberous sclerosis; f) acute leukaemia in one patient with Down syndrome and congenital heart disease; g) kidney tumour in one case with triventricular hydrocephaly, and h) adrenocortical tumour: hemihypertrophy. The publications included the tumours diagnosed in different pediatric periods and without unified criteria to classify the congenital abnormalities. Little data

    Abdominal surgery in foals under 30 days old has become more common with improved neonatal care. Early recognition of a foal at risk and better nursing care have increased the survival rates of foals that require neonatal care. The success of improved neonatal care also has increased the need for accurate diagnosis and treatment of gastrointestinal, umbilical, and bladder disorders in these foals. This chapter focuses on the early and accurate diagnosis of specific disorders that require abdominal exploratory surgery and the specific treatment considerations and prognosis for these disorders.

    Perinatal infection may potentiate brain injury among children born preterm. The objective of this study was to examine whether maternal and/or neonatal infection are associated with adverse outcomes among term neonates with encephalopathy. This study is a cohort study of 258 term newborns with encephalopathy whose clinical records were examined for signs of maternal infection (chorioamnionitis) and infant infection (sepsis). Multivariate regression was used to assess associations between infection, pattern, and severity of injury on neonatal magnetic resonance imaging, as well as neurodevelopment at 30 mo (neuromotor examination, or Bayley Scales of Infant Development, second edition mental development index encephalopathy, chorioamnionitis was associated with a lower risk of brain injury and adverse outcomes, whereas signs of neonatal sepsis carried an elevated risk. The etiology of encephalopathy and timing of infection and its associated inflammatory response may influence whether infection potentiates or mitigates injury in term newborns.

    Full Text Available Background and objectives: Reducing pain on injection of anesthetic drugs is of importance to every anesthesiologist. In this study we pursued to define if pretreatment by granisetron reduces the pain on injection of etomidate similar to lidocaine. Methods: Thirty patients aged between 18 and 50 years of American Society of Anesthesiologists physical status class I or II, whom were candidates for elective laparoscopic cholecystectomy surgery were enrolled in this study. Two 20 gauge cannulas were inserted into the veins on the dorsum of both hands and 100 mL of normal saline was administered during a 10 min period from each cannula. Using an elastic band as a tourniquet, venous drainage of both hands was occluded. 2 mL of granisetron was administered into one hand and 2 mL of lidocaine 2% at the same time into the other hand. One minute later the elastic band was opened and 2 mL of etomidate was administered to each hand with equal rates. The patients were asked to give a score from 0 to 10 (0 = no pain, 10 = severe pain to each the pain sensed in each hand. Results: Two patients were deeply sedated after injection of etomidate and unable to answer any questions. The mean numerical rating score for injection pain of intravenously administered etomidate after intravenous granisetron was 2.3 ± 1.7, which was lower when compared with pain sensed due to intravenously administered etomidate after administration of lidocaine 2% (4.6 ± 1.8, p < 0.05. Conclusion: The result of this study demonstrated that, granisetron reduces pain on injection of etomidate more efficiently than lidocaine. Resumo: Justificativa e objetivos: A redução da dor causada pela injeção de anestésicos é importante para todos os anestesiologistas.

    Respiratory distress is a very common and yet non-specific symptom in neonates and young infants. It may be manifested clinically in many ways, including tachypnea, apnea, periodic respiratory, grunting, retractions, nasal flaring, and cyanosis. In many instances, the chest radiograph is diagnostic or at least suggestive of the diagnosis. This fact is important in determining surgical or medical conditions that require emergency therapy. Even if the chest film is normal, valuable information can be gained. This initial normal radiograph can be used as a baseline film in the face of further developing symptoms which, likewise, may have developing radiographic findings. In any event, the chest radiograph gives the clinician ''direction'' in his or her search for the cause of the patient's respiratory distress

    Full Text Available Idiopathic pulmonary hemosiderosis (IPH is a rare complex entity characterized clinically by acute or recurrent episodes of hemoptysis secondary to diffuse alveolar hemorrhage. The radiographic features are variable, including diffuse alveolar-type infiltrates, and interstitial reticular and micronodular patterns. We describe a 3-week-old infant presenting with hemoptysis and moderate respiratory distress. Idiopathic pulmonary hemosiderosis was the first working diagnosis at the Emergency Department and was confirmed, 2 weeks later, by histological studies (bronchoalveolar lavage. The immunosuppressive therapy by 1 mg/kg/d prednisone was immediately started, the baby returned home on steroid therapy at a dose of 0,5 mg/kg/d. The diagnosis of idiopathic pulmonary hemosiderosis should be evocated at any age, even in the neonate, when the clinical presentation (hemoptysis and abnormal radiological chest images is strongly suggestive.

    Although largely deprived from exogenous stimuli in utero, the mucosal barriers of the neonate after birth are bombarded by environmental, nutritional, and microbial exposures. The microbiome is established concurrently with the developing immune system. The nature and timing of discrete interactions between these two factors underpins the long-term immune characteristics of these organs, and can set an individual on a trajectory towards or away from disease. Microbial exposures in the gastrointestinal and respiratory tracts are some of the key determinants of the overall immune tone at these mucosal barriers and represent a leading target for future intervention strategies. In this review, we discuss immune maturation in the gut and lung and how microbes have a central role in this process.

In the Danish research centre, NEOMUNE, premature piglets are fed...... a novel milk diet (bovine colostrum) to model the effects of this new diet in premature infants. Our ethnographic fieldwork in an experimental pig laboratory and a neonatal intensive care unit (NICU) in 2013–2014 shows that regardless of biogenetics, daily practices of feeding, housing, and clinical care...... the researchers refer to as the ‘translatability’ of the results. In the NICU, parents of premature infants likewise imagine a kind of interspecies kinship when presented with the option to supplement mother's own milk with bovine colostrum for the first weeks after birth. However, in this setting the NICU...

    Technological advances have caused a decrease in the number of infant deaths. Pre-term infants now have a substantially increased chance of survival. One of the mechanisms that is vital to saving the lives of these infants is continuous monitoring and early diagnosis. With continuous monitoring huge amounts of data are collected with so much information embedded in them. By using statistical analysis this information can be extracted and used to aid diagnosis and to understand development. In this study we have a large dataset containing over 180 pre-term infants whose heart rates were recorded over the length of their stay in the Neonatal Intensive Care Unit (NICU). We test two types of models, empirical bayesian and autoregressive moving average. We then attempt to predict future values.

    A pre-term baby girl was born following a pregnancy complicated by severe polyhydramnios at a gestational age of 36 weeks. She was initially suffering from respiratory distress consistent with idiopathic respiratory distress syndrome, and altered electrolyte imbalance with hyponatremia, hypokalemia and hypochloremic metabolic alkalosis. However, during the third week of life when she had dehydration along with significant electrolyte imbalance, Bartter's syndrome was considered which was supported by findings of high renin and aldosterone levels. Treatment was done by correction of electrolytes and dehydration along with indomethacin. The drug was well tolerated. The infant showed correction of electrolyte imbalance. The features of this case suggest an extreme form of Bartter's syndrome presenting from the early days of life. The syndrome is reported because of it's rarity and alerts pediatricians to the antenatal and neonatal variant of Bartter's syndrome. (author)

    Intra-articular injections of local anesthetics are commonly used to enhance post-operative analgesia following orthopedic surgery as arthroscopic surgeries. Nevertheless, recent reports of severe complications due to the use of intra-articular local anesthetic have raised concerns. The study aims to assess use of vitamin C in reducing adverse effects of the most commonly employed anesthetics - ropivacaine, bupivacaine and lidocaine - on human chondrocytes. The chondrocyte viability following exposure to 0.5% bupivacaine or 0.75% ropivacaine or 1.0% lidocaine and/or vitamin C at doses 125, 250 and 500μM was determined by Live/Dead assay and annexin V staining. Expression levels of caspases 3 and 9 were assessed using antibodies by Western blotting. Flow cytometry was performed to analyze the generation of reactive oxygen species. On exposure to the local anesthetics, chondrotoxicity was found in the order ropivacaineC effectively improved the reduced chondrocyte viability and decreased the raised apoptosis levels following exposure to anesthesia. At higher doses, vitamin C was found efficient in reducing the generation of reactive oxygen species and as well down-regulate the expressions of caspases 3 and 9. Vitamin C was observed to effectively protect chondrocytes against the toxic insult of local anesthetics ropivacaine, bupivacaine and lidocaine.

    2012-02-01

    Full Text Available Introduction: Suffering from de Quervain's tenosynovitis due to repetitive and routine activities leads to considerable referrals to orthopedic clinics and increasing health care costs and wasting of patients' time. The present study aimed to compare the efficacy of local injection of methylprednisolone with and without splint for treatment of patients suffering from de Quervain's tenosynovitis. Methods: In a clinical trial study, 72 patients with de Quervain's tenosynovitis were selected in 2010 and were randomly divided into two groups. Therapeutic intervention in the first group was injection of 40 mg methylprednisone and 1 ml lidocaine with splint, and in the second group it was injection 40 mg methylprednisone and 1ml lidocaine without splint. Both groups followed this treatment for three periods(21 day. The related data were collected by visual analogue scale. Then data was analyzed by SPSS (ver. 16 using Fisher exact test and t test. Results: The findings of this study revealed that after the 3-week period of treatment the mean reduced pain intensity and improvement in the first group was significantly lower than the second group(p<0/05. Conclusion: Therefore, local injection of methylprednisone and lidocaine with splint is an effective method in the treatment of de Quervain's tenosynovitis.

  5. Conditions sufficient for the production of oral cocaine or lidocaine self-administration in preference to water.

    Groups of rats were given a chronic history of drinking cocaine solutions of different concentrations in daily, 3-h schedule induced polydipsia sessions. Animals failed to develop a preference for cocaine solution to concurrently presented water. Schedule-induction conditions were maintained, and the animals were divided into separate groups, drinking either cocaine or lidocaine placed in a highly acceptable vehicle (glucose-saccharin solution). Animals preferred their respective drug solutions to concurrently presented water, and these preferences remained stable after the glucose-saccharin vehicle was gradually faded to water, leaving only cocaine or lidocaine, respectively, in the solution. Thus a stable preference for drug solution to water could be instituted in rats for either cocaine or lidocaine solution (putative reinforcing and nonreinforcing agents, respectively) given an appropriate associative history, with high intakes maintained by schedule-induction. Conditions sufficient for the initiation of an oral preference and high intake for a putatively reinforcing drug cannot be assumed to occur owing to the drug's reinforcing property in the absence of demonstrating the ineffectiveness of an appropriate negative control substance.

    To compare the local anesthetic effects of tramadol hydrochloride with those of lidocaine in circumcision procedures. We also investigated the effect of child anxiety on pain level. A total of 70 children were included in this study. The children were randomized into 3 groups. Group 1 (n = 26) received lidocaine hydrochloride + epinephrine and they underwent circumcision using Ali's clamp(®). Group 2 (n = 35) received lidocaine hydrochloride + epinephrine and group 3 (n = 12) 5% tramadol. The last two groups underwent conventional circumcision. The mean anxiety score was 22.6. We did not find significant differences in terms of anxiety score among the groups (p = 0.761). When the pain scores of the groups during injection were compared, it was found that there were no significant differences. However, the pain score of the third group was significantly high when it was compared with the first and second group 2 and 10 min after injection. In the correlation analysis, we found a positive correlation between children's anxiety scores and the pain degree during injection (r = 0.373, p = 0.001). Tramadol may not provide effective local anesthesia in male circumcision. The child's anxiety before the circumcision seems to have a negative effect on pain level.

    To establish a liquid chromatography tandem mass spectrometry (HPLC-MS/MS) method for the determination of lidocaine (LDC) and its metabolites, monoethylglycinexylidide (MEGX) and glycinexylidide (GX), in human plasma. METHODS; The assay was conducted with an API 3000 HPLC-MS/MS system consisted of a Ultimate C18 column (50 x 4.6 mm, 5 microm). The mobile phase consisted of methanol: 5 mmol/ L ammonium acetate (50:50, pH was adjusted to 5.0 by formic acid) and the flow rate was set at 0.2 mL/min. The alkalinized sample was extracted with ethyl acetate. After evaporation of the organic layer, the residue was dissolved in mobile phase and the drug was determined by HPLC-MS/MS using electrospray ionization. The calibration curve was linear in a range from 15.625 to 2000 ng/mL for LDC. Linear calibration curves were obtained in the range of 1.5625 to 200 ng/mL for both for MEGX and GX. The limit of quantification for LDC, MEGX and GX was set at 15.625, 1.5625 and 1.5625 ng/mL. This method for the quantitative determination of lidocaine and its metabolites in human plasma is simple, rapid, sensitive and accurate. Therefore it can be used for the determination of lidocaine and its metabolites in clinical practice.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer

Departamento de Medicina e Cirurgia Veterinária, Instituto de Veterinária, Universidade Federal Rural do Rio de Janeiro, BR 465 Km 7, Seropédica RJ 23890-000, Brasil. E-mail: saulocaldas@hotmail.com A case of bilateral queilosquise in a cattle two years old was reported. Clinically, there was cachexia, difficulty in grasping food and water intake. The clinical examination revealed that the nasal orifices were discontinuous with the upper lip, which allowed communication between the nostrils and mouth in its rostral portion, crowding of incisors (tweezers, as well as exposure of medium and the 2nd corner and of the tongue. In this case, the bilateral queilosquise was the result of flaws in fusion of the maxillary process and the medial nasal process and its surroundings, probably due to mineral deficiencies of pregnant cow. This pathogenesis was suggested by excluding other possible causes, the knowledge of the existence of mineral deficiencies in the region where the event occurred and bad nutritional status of pregnant female.

    A case of bilateral fibrotic contracture of the infraspinatus muscles in a five-year-old Belgian Shepherd dog is described. The dog was presented with progressive forelimb lameness with postural and gait abnormalities three months after an episode of overexertion. When walking, the lower part of both forelimbs swung in a lateral arc causing a circumduction movement and in the standing position, the dog showed elbow adduction with external rotation of the distal part of both front limbs. Orthopaedic examination revealed bilateral atrophy of both infraspinatus and supraspinatus muscles and restriction in the range of motion of both shoulders, especially when attempting abduction and flexion. No specific findings were observed in the shoulder or elbow radiographs but hyperechogenic areas were evident in the ultrasonographic examination of both infraspinatus muscles. A diagnosis of fibrotic contracture of both infraspinatus muscles was established and bilateral tenectomy of the insertion tendons of the infraspinatus muscles was performed. Complete recovery of the animal was achieved after the surgery, which was confirmed in a long-term follow-up (10 months). In conclusion, physical examination and ultrasonography allowed a proper diagnosis of the condition, and tenectomy of the infraspinatus muscles resulted in a complete recovery of the patient even with bilateral involvement.

    Full Text Available The article deals with the author’s interpretation of the process of teaching profession specific bilateral translation to student teacher of English in the Master’s program. The goal of the model of teaching profession specific bilateral translation development is to determine the logical sequence of educational activities of the teacher as the organizer of the educational process and students as its members. English and Ukrainian texts on methods of foreign languages and cultures teaching are defined as the object of study. Learning activities aimed at the development of student teachers of English profession specific competence in bilateral translation and Translation Proficiency Language Portfolio for Student Teachers of English are suggested as teaching tools. The realization of the model of teaching profession specific bilateral translation to student teachers of English in the Master’s program is suggested within the module topics of the academic discipline «Practice of English as the first foreign language»: Globalization; Localization; Education; Work; The role of new communication technologies in personal and professional development. We believe that the amount of time needed for efficient functioning of the model is 48 academic hours, which was determined by calculating the total number of academic hours allotted for the academic discipline «Practice of English as the first foreign language» in Ukrainian universities. Peculiarities of the model realization as well as learning goals and content of class activities and home self-study work of students are outlined.

    Purpose: To assess outcome of patients with bilateral breast carcinoma treated with bilateral breast conserving surgery with radiation therapy (CS+RT) and to compare their outcome to (1) patients with unilateral disease treated with CS+RT and (2) patients of comparable stage treated with bilateral mastectomy. Methods and Materials: The charts of all patients with the diagnosis of breast cancer treated with CS+RT at our facilities prior to 1993 were reviewed to identify patients with bilateral disease. A total of 50 patients identified as having bilateral breast cancer conservatively treated(BCT) served as the index population. Out of the 50 patients, 23 presented with synchronous bilateral breast cancer and 27 presented with metachronous bilateral breast cancer. A group of 984 patients with unilateral breast cancer (UCT) treated with CS+RT during the same time interval served as the first control group. A second control group was comprised of 42 patients with early stage bilateral breast cancer presenting during the same time interval treated with bilateral mastectomy (BMAST). Patients who had locally advanced disease in either breast or those patients treated exclusively for lobular carcinoma in situ in either breast were excluded from the analysis. Of the 42 BMAST patients, 33 presented with synchronous disease and nine presented with metachronous disease. Local-regional relapse rates were calculated from the date of treatment of each breast. Overall survival and distant relapse rates were calculated from the date of treatment of the second breast cancer diagnosed. Survival curves were calculated via the life table method and statistical comparisons between curves were performed using the log rank statistic. Chi square analysis was used to detect differences between categorical variables. Results: As of December 1995, the median follow-up of the bilateral conservatively treated patient population was 9.4 years. No statistically significant differences were noted

    Full Text Available Introduction: The incidence of tumors of the upper urothelium is high in our country, apart from their relation to specific regions (BEN and PBEN and their frequent bilateralism. Bilateral forms are present in significant percentage and are followed, in most cases, by renal failure, which speaks in favor of conservative surgery, if possible. Objective: The aim of the study was to present epidemiological, pathoanatomical and clinical characteristics of bilateral tumors of the upper urothelium and evaluate the Results of their treatment. Method: Our retrospective study analyzed 12 patients with bilateral tumors of the upper urothelium who were treated in the period from 1992 to 1996, according to their epidemiological, clinical, pathoanatomical and pathohistological characteristics, type of surgical treatment and relevant success. Results: In the observed period, bilateral tumors of the upper urothelium were found in 8.2% of our patients. In the group of 12 patients, 5 females and 7 males, 11 cases were from the region of Balkan Endemic Nephropathy (BEN. Renal failure was recorded in high percentage (66%. Radical surgical treatment - total nephroureterectomy was performed in 9 kidney units, and conservative operation in 15 units. Relapse significantly depended on tumor stage and grade, not on type of surgical treatment in the majority of cases. Five-year survival was 58.33%; major cause of death was associated with further evolution of tumor, recurrence and tumor dissemination, respectively, while renal failure complications were the cause of death in one case. Conclusion: The success of treatment mainly depends on tumor stage and grade and not on type of surgical Method in conservative treatment, but renal failure and its complications are an important risk factor in these patients.

    2015-01-01

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

    Full Text Available Background: Neonatal hyperbilirubinemia (NHB is a common clinical disease and can cause bilirubin encephalopathy in severe cases. It is now widely accepted that increased signal intensity in the globus pallidus on MR T1WI is an important sign of neonatal bilirubin encephalopathy. And brain diffusion tensor imaging (DTI has not been used extensively to study hyperbilirubinemia (HB. So we compared newborns with different hyperbilirubinemia of different severities and healthy newborns in order to determine the relationships among MRI signal intensities, serum bilirubin levels, and the molecular changes in brain water diffusion in hyperbilirubinemia. Methods: Seventy-three newborns with hyperbilirubinemia were grouped into three groups: the mild increase group (M, 27 cases, the moderate increase group (O, 28 cases, and the severe group (S, 18 cases. The groups were based on serum bilirubin levels. We performed cranial MRI in these newborns, as well as 29 healthy full-term infants (group N. We compared and analyzed the mean signal values for the globus pallidus and the relationship between the bilirubin level and the score on the neonatal behavioral neurological assessment. Fifteen, 10, and 10 patients in groups M, O + S, and N were successfully examined using diffusion tensor imaging (DTI. We assessed the relationships among the signal from the globus pallidus, fractional anisotropy (FA, and average diffusion coefficient (DCav of the posterior limb of the internal capsule (PLIC. Results: There were significant differences in the mean signal value of bilateral globus pallidus between group O/S and group N [p = 0.029 and 0.000 (left, 0.038 and 0.000 (right]. There were no significant differences in bilateral FA or DCav values between the patient groups and group N. The bilateral PLIC-FA and DCav values were significantly different between the patient groups and group N (P = 0.014 and 0.047, respectively. Conclusions: Increased signal intensity

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    Pyruvate dehydrogenase (PDH) deficiency is one of the most common causes of congenital lactic acidosis. Correlations between the genetic defect and neuroimaging findings are lacking. We present conventional and diffusion-weighted MRI findings in a 7-day-old male neonate with PDH deficiency due to a mosaicism for the R302H mutation in the PDHA1 gene. Corpus callosum dysgenesis, widespread increased diffusion in the white matter, and bilateral subependymal cysts were the main features. Although confirmation of PDH deficiency depends on specialized biochemical analyses, neonatal MRI plays a role in evaluating the pattern and extent of brain damage, and potentially in early diagnosis and clinical decision making.

    Full Text Available OBJETIVO: comparar el tratamiento convencional del retinoblastoma bilateral, usado hasta hace algunos años, consistente en radioterapia o enucleación bilateral, con el tratamiento conservador actual que incluye termoterapia transpupilar (TTT o TTT/quimioterapia al menos en un ojo, en niños con diagnóstico de retinoblastoma bilateral. DISEÑO: estudio retrospectivo descriptivo. MUESTRA: 20 pacientes con diagnóstico de retinoblastoma bilateral que consultaron al Hospital Universitario San Vicente de Paúl, de Medellín, Colombia, entre 1997 y 2007. MÉTODO: se hizo enucleación del ojo con el tumor de mayor tamaño. En el otro ojo se hizo tratamiento con TTT, con el láser diodo (810 nm, spot amplio, solo o combinado con otras terapias. RESULTADOS: se dividió a los pacientes en dos grupos: 16 pacientes (32 ojos en el grupo 1 tratados conservadoramente y 4 pacientes (8 ojos en el grupo 2 con tratamiento convencional. El rango de edad fue de 1-72 meses en el grupo 1 y de 1-12 meses en el grupo 2. El tiempo de seguimiento fue de 7-67 meses para el grupo 1 y de 13-73 meses para el grupo 2. En el grupo 1 se hizo enucleación de 16 ojos (50%, radioterapia externa de uno (3,1%, quimioterapia más termoterapia de 5 (15,6% y quimioterapia más termoterapia más crioterapia de 10 (31,3%. En todos los pacientes se logró preservar al menos un ojo. En el grupo 2, se enuclearon 7 ojos (87,5% y se hizo radioterapia externa más enucleación en un paciente (12.5%. Además, todos los pacientes recibieron quimioterapia. CONCLUSIÓN: la terapia conservadora actual consistente en tratamiento local (termoterapia, crioterapia o braquiterapia y quimiorreducción permite preservar al menos un ojo y en algunos casos de los dos, muchas veces con buena agudeza visual, en niños con retinoblastoma bilateral; se evitan así la enucleación bilateral y la radioterapia externa usada en el tratamiento convencional con todos sus efectos secundarios. La enucleación contin

    Thin film flow chemistry using a vortex fluidic device (VFD) is effective in the scalable acylation of amines under shear, with the yields of the amides dramatically enhanced relative to traditional batch techniques. The optimized monophasic flow conditions are effective in ≤80 seconds at room temperature, enabling access to structurally diverse amides, functionalized amino acids and substituted ureas on multigram scales. Amide synthesis under flow was also extended to a total synthesis of local anesthetic lidocaine, with sequential reactions carried out in two serially linked VFD units. The synthesis could also be executed in a single VFD, in which the tandem reactions involve reagent delivery at different positions along the rapidly rotating tube with in situ solvent replacement, as a molecular assembly line process. This further highlights the versatility of the VFD in organic synthesis, as does the finding of a remarkably efficient debenzylation of p-methoxybenzyl amines. © 2015 WILEY-VCH Verlag GmbH & Co.
