Purpose The purpose of the present study was to perform a pattern analysis in patients with temporomandibular disorder (TMD) resulting from unilateral mastication due to chronic periodontitis. Methods Thirty participants with signs or symptoms of TMD who engaged in unilateral mastication due to periodontitis-related discomfort (test group) were selected. Another 30 subjects exhibiting signs or symptoms of TMD resulting from unilateral mastication not due to chronic periodontitis (control group) were also recruited. An interview-based questionnaire was administered, and an examination of the temporomandibular joint (TMJ) with determination of periodontal status was performed. Results The duration of unilateral mastication was significantly longer in the control group than in the test group. There was a significant negative correlation between the duration of unilateral mastication and the Community Periodontal Index score. Using the Research Diagnostic Criteria for TMD (RDC/TMD) axis I algorithms, all the subjects were assigned to 3 main groups. The test group exhibited significantly a higher diagnostic distribution of group III (arthralgia, osteoarthritis, or osteoarthrosis), and in both the test and control groups, the number of diagnoses was larger for the non-chewing side. The control group showed a significantly higher diagnostic distribution of group I (myofacial pain), and in both the test and control groups, the number of diagnoses was larger for the chewing side. Conclusions The results of the present study indicate that unilateral mastication due to chronic periodontitis could induce not only pain but also structural TMJ changes if adequate treatment is not administered and supported within a short time from the onset of the condition. Therefore, immediate treatment of chronic periodontitis is recommended to prevent not only the primary progress of periodontal disease, but also secondary TMJ-related problems. Furthermore, subjects who have suffered chronic

Ictal motor phenomena play a crucial role in the localization of seizure focus in the management of refractory focal epilepsy. While the importance of unilateral automatisms is well established, little attention is paid to the contralateral relatively immobile limb. In cases where automatisms mimic clonic or dystonic movements and in the absence of previously well-established signs, unilateral relative ictal immobility (RII) is potentially useful as a lateralizing sign. This study was carried out to examine the lateralizing value of this sign and to define its characteristics among patients of refractory focal epilepsy. VEEGs of 69 consecutive patients of refractory focal epilepsy who had undergone epilepsy surgery at our center over last four years were reviewed and analyzed for the presence of RII. Unilateral RII was defined as a paucity of movement in one limb lasting for at least 10s while the contralateral limb showed purposive or semi-purposive movements (in the absence of tonic or dystonic posturing or clonic movements in the involved limb). The findings were seen in the light of VEEG, radiological and nuclear imaging data, and with post-surgical outcome. Unilateral RII as a lateralizing sign was found in 24 of 69 patients (34.78%), consisting of both temporal and extra temporal epilepsy, with 100% concordance with VEEG and MRI data. All patients demonstrating this sign had a good post-surgical outcome. RII, when well characterized is a frequent and reliable lateralizing sign in patients of refractory focal epilepsy.

A best evidence topic in cardiovascular surgery was written according to a structured protocol. The question addressed was whether patients with severe asymptomatic carotid and coronary artery diseases should undergo simultaneous carotid endarterectomy (CEA) and coronary artery bypass grafting (CABG). A total of 624 papers were found using the reported search, of which 20 represent the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study results of these papers are tabulated. Previous cohort studies showed mixed results, while advocating for the necessity of a randomized controlled trial (RCT). A recent RCT showed that patients undergoing prophylactic or simultaneous CEA + CABG had lower rates of stroke (0%) compared with delayed CEA 1–3 months after CABG (7.7%), without significant perioperative mortality difference. This study included patients with unilateral severe (>70%) asymptomatic carotid stenosis requiring CABG. An earlier partly randomized trial also showed better outcomes for patients undergoing simultaneous procedures (P = 0.045). Interestingly, systematic reviews previously failed to show compelling evidence supporting prophylactic CEA. This could be partly due to the fact that these reviews collectively analyse different cohort qualities. Neurological studies have, however, shown reduced cognitive and phonetic quality and function in patients with unilateral and bilateral asymptomatic carotid artery stenosis. Twenty-one RCTs comparing lone carotid artery stenting (CAS) and CEA informed the American Heart Association guidelines, which declared CAS comparable with CEA for symptomatic and asymptomatic carotid stenosis (CS). However, the risk of death/stroke for CAS alone is double that for CEA alone in the acute phase following onset of symptoms, while CEA alone is associated with a doubled risk of myocardial infarction.

Intralaryngeal muscle synkinesis associated with unilateral vocal fold paralysis (UVFP) is thought to preserve thyroarytenoid-lateral cricoarytenoid muscle complex tone, resulting in a better voice despite the presence of vocal fold paralysis (VFP). This study compares voice handicap in patients with unilateral VFP (UVFP) with and without evidence of adductory synkinesis on laryngeal electromyography (LEMG). Retrospective review of LEMG data and Voice Handicap Index-10 (VHI-10) scores of patients diagnosed with permanent UVFP. LEMG was performed within 1 to 6 months post onset of UVFP. Patients were stratified into two groups: 1) recurrent laryngeal nerve (RLN) neuropathy with synkinesis and 2) RLN neuropathy without synkinesis. Synkinesis was diagnosed when the sniff to phonation maximum amplitude ratio was ≥0.65. VHI-10 scores at 6-month follow-up were recorded. Four hundred forty-nine patients with UVFP and who had an LEMG were reviewed. Eighty-three patients met the inclusion criteria, with 16 in group 1 and 67 in group 2. There was no significant difference between the groups with regard to age, timing of LEMG from onset of VFP, number of patients undergoing temporary vocal fold injection or use of off-label nimodipine. Average VHI-10 scores at 6 months post onset of VFP were 14.4 ± 10.6 for patients with LEMG-identified synkinesis (group 1) and 21.0 ± 10.1 for patients with no LEMG evidence of synkinesis (group 2). This was statistically significant (P = .02). Patients with unilateral vocal fold paralysis and LEMG evidence of laryngeal synkinesis are more likely to have less perceived voice handicap than those without synkinesis. 4.

Restriction of sympathetic denervation during spinal anesthesia may minimize hemodynamic alterations. Theoretically, the use of nonisobaric anesthetics may allow unilateral anesthesia and thus restrict sympathetic denervation to one side of the body. The present prospective study investigates the incidence of unilateral spinal anesthesia using hyperbaric bupivacaine 0.5% (1.4 mL, 1.6 mL, 1.8 mL, or 2.0 mL) injected via a 29-gauge Quincke needle with a pump-controlled injection flow of 1 mL/min. In 96 consecutive patients undergoing unilateral surgery of the lower extremities, spinal anesthesia was performed in the lateral decubitus position, which was maintained for 20 min postinjection. Increases in foot temperature of at least 0.5 degrees C were defined as sympathetic blockade. The incidence of unilateral block was not significantly influenced by the amount of bupivacaine. For all 96 patients, the incidence of unilateral sympathetic and complete motor block was 69% and 77%, respectively. Frequency of unilateral sensory block (assessed by pinprick and temperature discrimination) was significantly lower (28%). Strict unilateral spinal anesthesia was achieved in 24 cases (25%). Twenty minutes after injection of the local anesthetic, mean arterial blood pressure decreased significantly in patients with bilateral sympathetic blockade from 87 +/- 8 to 83 +/- 8 mm Hg (P < 0.01) but not in patients with unilateral sympathetic blockade (from 87 +/- 11 to 85 +/- 10 mm Hg). In conclusion, low-flow injection (1 mL/min) of hyperbaric bupivacaine 0.5% via a 29-gauge Quincke needle prevented bilateral sympathetic blockade in more than 69% of the patients. The data further suggest that loss of temperature discrimination alone is not a reliable estimation of sympathetic block.

To analyze characteristics of mandibular movement in patients with unilateral mastication.
 Undergraduate students in oral medicine from Grade 2011 and 2012 in Wannan Medical College were enrolled for this study by cluster sampling method, which include 30 people with unilateral mastication and 30 people with bilateral mastication. The surface electromyogram (sEMG) of masseter muscle and anterovent of digastric muscle were recorded and the trajectory of mandibular incisor point was recorded simultaneously in the maximum opening and closing movement. The results were analyzed by SPSS 19.0 software.
 Average electrical peak of left anterior digastric muscle and right anterior digastric muscle in the unilateral chewing group was lower than that in the bilateral chewing group (P<0.05). The jaw tangent point trajectory was separate in the unilateral chewing group. There were significant differences at the opening type between the 2 groups. The vertical displacement and the sagittal displacement in the unilateral chewing group were significantly lower than those in the bilateral chewing group (P<0.01). There was significant positive correlation between the average peak potential of masseter muscle and displacement on the right side.
 Average electrical peak of left masseter muscle, left anterior digastric muscle, and right anterior digastric muscle decreases in the unilateral chewing group. Jaw tracking in most people deflects to the working side. Opening and closing jaw tracking is separate in 50% unilateral chewing individuals with the decreased opening degree. Unilateral chewing leads to changes in muscle performance accompanied by trajectory anomalies.

To evaluate the change in ocular function by eye in patients with unilateral pigmentary retinopathy. Longitudinal regression was used to estimate mean exponential rates of change in Goldmann visual field area (V4e white test light) and in full-field electroretinogram (ERG) amplitudes to 0.5- and 30-Hz white flashes in 15 patients with unilateral pigmentary retinopathy. Snellen visual acuity was assessed case by case. Mean annual rates of change for the affected eyes were -4.9% for visual field area, -4.7% for ERG amplitude to 0.5-Hz flashes, and -4.6% for ERG amplitude to 30-Hz flashes. All three rates were faster than the corresponding age-related rates of change for the fellow normal eyes (P = 0.0006, P = 0.003, P = 0.03, respectively). An initial cone ERG implicit time to 30-Hz flashes in affected eyes ≥ 40 ms predicted a faster mean rate of decline of visual field area and of ERG amplitude to 0.5- and 30-Hz flashes (P < 0.0001 for all three measures). The visual acuity of affected eyes was more likely to decrease in patients presenting at >35 years of age than in patients presenting at a younger age (P = 0.0004). The affected eye in unilateral pigmentary retinopathy shows a progressive loss of peripheral retinal function that cannot be attributed to aging alone and that is faster in eyes with a more prolonged initial cone ERG implicit time. Patients presenting at >35 years of age are at greater risk for losing visual acuity.

Renal artery stenosis is a potential cause of secondary hypertension, ischemic nephropathy and end-stage renal disease. Atherosclerosis is by far the most common etiology of renal artery stenosis in elderly. We investigated whether the presence of significant atherosclerotic renal artery stenosis (ARAS) with luminal diameter narrowing ≥50 % could be predicted in patients undergoing peripheral and coronary angiography. The records of 3,500 consecutive patients undergoing simultaneous renal angiography along with peripheral and coronary angiography were reviewed. The patients with known renal artery disease were excluded. Prevalence of ARAS was 5.7 %. Significant ARAS (luminal diameter narrowing ≥50 %) was present in 139 patients (3.9 %). Hypertension with altered serum creatinine and triple-vessel CAD were associated with significant renal artery stenosis in multivariate analysis. No significant relationship between the involved coronary arteries like left anterior descending, left circumflex, right coronary artery and ARAS was found. Only hypertension and altered serum creatinine were associated with bilateral ARAS. Extent of CAD or risk factors like diabetes, hyperlipidemia or smoking did not predict the unilateral or bilateral ARAS. Prevalence of ARAS among the patients in routine cardiac catheterization was 5.7 %. Hypertension is closely associated with significant ARAS. Significant CAD in the form of triple-vessel disease and altered renal function tests are closely associated with ARAS. They predict the presence of significant renal artery stenosis in patients undergoing routine peripheral and coronary angiography. Moreover, hypertension and altered renal functions predict bilateral ARAS.

To investigate the use and success rate of hysteroscopic tubal electrocoagulation for the treatment of hydrosalpinx-related infertility among patients undergoing in vitro fertilization (IVF) who have laparoscopic contraindications. A prospective study was conducted among patients who had unilateral or bilateral hydrosalpinges identified on hysterosalpingography and vaginal ultrasonography, and who were undergoing IVF at a center in Cairo, Egypt, between January 1, 2013, and October 30, 2014. All patients who had contraindications for laparoscopy were scheduled for hysteroscopic tubal electrocoagulation (group 1); the other patients underwent laparoscopic tubal ligation (group 2). For all patients, hysterosalpingography was performed 3 months after their procedure to evaluate proximal tubal occlusion. Among 85 enrolled patients, 22 underwent hysteroscopic tubal electrocoagulation and 63 underwent laparoscopic tubal ligation. The procedure was successful in terms of tubal occlusion for 25 (93%) of 27 hydrosalpinges in group 1, and 78 (96%) of 81 hydrosalpinges in group 2 (P=0.597). No intraoperative or postoperative complications were reported. Hysteroscopic tubal electrocoagulation was found to be a successful treatment for hydrosalpinges before IVF when laparoscopy is contraindicated.

How to quantify binaural hearing in patients with unilateral hearing using hearing implants.

PubMed

Snik, Ad; Agterberg, Martijn; Bosman, Arjan

2015-01-01

Application of bilateral hearing devices in bilateral hearing loss and unilateral application in unilateral hearing loss (second ear with normal hearing) does not a priori lead to binaural hearing. An overview is presented on several measures of binaural benefits that have been used in patients with unilateral or bilateral deafness using one or two cochlear implants, respectively, and in patients with unilateral or bilateral conductive/mixed hearing loss using one or two percutaneous bone conduction implants (BCDs), respectively. Overall, according to this overview, the most significant and sensitive measure is the benefit in directional hearing. Measures using speech (viz. binaural summation, binaural squelch or use of the head shadow effect) showed minor benefits, except for patients with bilateral conductive/mixed hearing loss using two BCDs. Although less feasible in daily practise, the binaural masking level difference test seems to be a promising option in the assessment of binaural function. © 2015 S. Karger AG, Basel.

This study investigated the distractive effect of a unilateral pivot splint on patients with unilateral disc displacement without reduction. The study group was comprised of 18 patients who had no history of treatment with removable prosthetic restorations of molars, premolars, or canine teeth, and no previous treatment for temporomandibular disorder. Joint spaces measurements made on magnetic resonance images indicated the affected side to be narrower than the healthy side. Unilateral distraction splints were made for all patients. An ultrasonic motion analyzer was used to measure the vertical shift occurring on the affected side as patients closed their mouths with maximal force with the splint in their mouths. Closing with maximal force on the unilateral distraction splint led to a noticeable downward movement of the affected condyle. The findings of this study indicate that the TMJ condyle of patients with unilateral disc displacement without reduction may be unilaterally distracted if the articular space is narrowed.

The injection of small doses of local anesthetic solutions through pencil-point directional needles and maintaining the lateral decubitus position for 15 to 30 minutes after the injection have been suggested to facilitate the unilateral distribution of spinal anesthesia. We evaluated the effects of hypobaric and hyperbaric bupivacaine in attempting to achieve unilateral spinal anesthesia for patients undergoing lower limb orthopedic surgery. Fifty patients were randomly allocated into 2 groups to receive either 1.5 mL hyperbaric bupivacaine 0.5% (7.5 mg; n = 25) or 4.2 mL hypobaric bupivacaine 0.18% (7.5 mg; n = 25). Drugs were administered at the L3-4 interspace with the patient in the lateral position. Patients remained in this position for 15 minutes before turning supine for the operation. Spinal block was assessed by pinprick and modified Bromage scale on both sides. Unilateral spinal block was observed in 20 patients in the hyperbaric group (80%) and in 19 patients in the hypobaric group (76%) while in the lateral position. However, 15 minutes after patients were turned supine, unilateral spinal anesthesia decreased to 68% of cases in the hyperbaric group and 24% of cases in the hypobaric group (P <.05). The motor block was more intense during the first 5 and 10 minutes (P <.05), but at the end of operation there was no difference between the groups. The hemodynamic changes were similar between the groups. As a result, unilateral spinal anesthesia with hyperbaric and hypobaric bupivacaine provided a rapid motor and sensory recovery and good hemodynamic stability, but more unilateral spinal block was achieved in patients in the hyperbaric group when compared with patients in the hypobaric group.

To study the diagnostic and prognostic contribution of laryngeal electromyography in unilateral vocal-fold immobility in adults. A retrospective study included patients with unilateral vocal-fold immobility undergoing laryngeal electromyography between 2007 and 2015. Neurogenic, normal or myogenic findings were compared to the clinical aspect. Prognosis for recovery was assessed from motor unit potentials on laryngeal electromyography, and compared to subsequent progress on laryngoscopy. Sixty-three patients (mean age, 59 years) were initially included; 2 were subsequently excluded from analysis. Mean time from onset of immobility to laryngeal electromyography was 7 months. 85% of the 61 patients showed neurogenic findings, indicating neural lesion; 13% showed normal electromyography, indicating cricoarytenoid joint ankylosis; and 1 patient showed a myogenic pattern. Neurogenic cases were usually secondary to cervical surgery. Thirty-eight patients were followed up. In total, 75% of patients showing reinnervation potentials recovered. The positive predictive value of laryngeal electromyography was 69.2%. Laryngeal electromyography is effective in specifying the origin of unilateral vocal-fold immobility in adults. It also has a prognostic role, lack of reinnervation potentials being a possible indication for early medialization surgery. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Objective To evaluate the clinical and histopathological results of adult unilateral cryptorchidism patients. Material and methods Data from adult unilateral cryptorchidism patients that underwent orchiectomy in our clinic between between January 2004 and March 2013 were retrospectively evaluated. Patients were divided into three groups as intra-abdominal, inguinal canal and superficial inguinal region according to the location of the undescended testes. Patients were also grouped according to their testicular volume (<4 cc, 4.1–12 cc, and >12 cc). Histopathology results of orchiectomy specimens were classified as follows: 1. Sertoli cells only, testicular atrophy and vanished testis (anorchia) 2. Hypospermatogenesis, and 3. Maturation arrest. Patients were grouped as normospermia, azoospermia and oligo/astheno/teratospermia groups according to semen analysis results. Correlations between testicular localization, testicular size, semen analysis and pathology results were evaluated. Incidental tumor detection rates were also calculated. Results Two hundred and forty-four adult unilateral cryptorchidism patients underwent orchiectomy in our clinic. There was no a significant relationship between location of the testis and testicular pathology results (p=0.707). Most common semen analysis results was normospermia in patients with high testicular volume group however azoospermia and oligoasthenospermia observed commonly in patients with low testicular volume group. There was a significant relationship between testicular volume and semen analysis results (p=0.023). No significant relationship was observed between semen analysis and pathological results (p=0.929). After an evaluation of all factors with possible effects on the semen analysis results, only testicular volume (p=0.036) was found to have a significant impact. Only one case (0.4%) was incidentally diagnosed seminoma after a review of 233 patients with available histopathological results on record

The incidence of inferior vestibular nerve disorders in patients suffering from unilateral vestibular neuritis and the recovery of these disorders were evaluated by monitoring the vestibular-evoked myogenic potential (VEMP). Eight patients ranged from 21 to 73 years that suffered from unilateral vestibular neuritis underwent VEMP and caloric testing. Abnormal VEMP was observed in two of the eight patients with unilateral vestibular neuritis. Two patients were diagnosed as having an inferior vestibular nerve disorder. One of these patients showed recovery of the inferior vestibular nerve function as assessed by the VEMP. Disorders of the inferior vestibular nerve function and their recovery was confirmed by our current results. The time course of recoveries of the superior and inferior vestibular nerve systems were similar in the two patients.

2015-03-01

The purpose of the present study was to investigate the relationship between Korean language-specific dysgraphia and unilateral spatial neglect in 31 right brain stroke patients. All patients were tested for writing errors in spontaneous writing, dictation, and copying tests. The dysgraphia was classified into visuospatial omission, visuospatial destruction, syllabic tilting, stroke omission, stroke addition, and stroke tilting. Twenty-three (77.4%) of the 31 patients made dysgraphia and 18 (58.1%) demonstrated unilateral spatial neglect. The visuospatial omission was the most common dysgraphia followed by stroke addition and omission errors. The highest number of errors was made in the copying and the least was in the spontaneous writing test. Patients with unilateral spatial neglect made a significantly higher number of dysgraphia in the copying test than those without. We identified specific dysgraphia features such as a right side space omission and a vertical stroke addition in Korean right brain stroke patients. In conclusion, unilateral spatial neglect influences copy writing system of Korean language in patients with right brain stroke.

Transforaminal lumbar interbody fusion (TLIF) with segmental pedicular instrumentation is a well established procedure used to treat lumbar spondylosis with or without spondylolisthesis. Available biomechanical and clinical studies that compared unilateral and bilateral constructs have produced conflicting data regarding patient outcomes and hardware complications. A prospective cohort study was undertaken by a group of neurosurgeons. They prospectively enrolled 80 patients into either bilateral or unilateral pedicle screw instrumentation groups (40 patients/group). Demographic data collected for each group included sex, age, body mass index, tobacco use, and Workers' Compensation/litigation status. Operative data included segments operated on, number of levels involved, estimated blood loss, length of hospital stay, and perioperative complications. Long-term outcomes (hardware malfunction, wound dehiscence, and pseudarthrosis) were recorded. For all patients, preoperative baseline and 6-month postoperative scores for Medical Outcomes 36-Item Short Form Health Survey (SF-36) outcomes were recorded. Patient follow-up times ranged from 37 to 63 months (mean 52 months). No patients were lost to follow-up. The patients who underwent unilateral pedicle screw instrumentation (unilateral cohort) were slightly younger than those who underwent bilateral pedicle screw instrumentation (bilateral cohort) (mean age 42 vs. 47 years, respectively; p = 0.02). No other significant differences were detected between cohorts with regard to demographic data, mean number of lumbar levels operated on, or distribution of the levels operated on. Estimated blood loss was higher for patients in the bilateral cohort, but length of stay was similar for patients in both cohorts. The incidence of pseudarthrosis was significantly higher among patients in the unilateral cohort (7 patients [17.5%]) than among those in the bilateral cohort (1 patient [2.5%]) (p = 0.02). Wound dehiscence occurred for

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare but well-reported clinical entity. It is classically described as symmetrical involvement of both upper extremities. Asymmetrical involvement had also been reported, but unilateral presentation is very rare. We hereby report a case of unilateral RS3PE in a patient of seronegative rheumatoid arthritis which was initially misdiagnosed as cellulitis and was given high dose antibiotics without any significant improvement. Later a rheumatologic consultation leads to a prompt diagnosis, and treatment with steroids leads to dramatic reversal of symptoms. This case demonstrates the rare presentation of this rare clinical entity and highlights the necessity of awareness regarding unilateral disease to clinicians. PMID:23662237

Unilateral spinal anesthesia is beneficial in patients undergoing unilateral leg surgery. The direction and the shape of the spinal needle are thought to influence the unilateral distribution of the local anesthetic in the intrathecal space. Therefore, to study the effects of different spinal needles we compared the effects of the Whitacre and Quincke spinal needles. This was a prospective, randomized, double-blind study of 60 consecutive outpatients scheduled for unilateral lower-limb surgery. The patients were randomized to receive spinal anesthesia with 1.2 ml of 0.5 % plain bupivacaine using either a 27-G Whitacre or a Quincke needle. One half of the local anesthetic was injected towards the nondependent side and the other half was directed cranially. The spread of spinal anesthesia, both sensory and motor blocks, was defined as the primary endpoint and was recorded at 10, 20, and 30 min after the spinal injection, at the end of the operation, 2 h after the spinal injection, and every 30 min thereafter until there was no motor block. Secondary endpoints included patient satisfaction and adverse effects. There was no difference in the spread of sensory or motor blocks between the Whitacre and the Quincke groups. However, the sensory and motor blocks on the operated and the nonoperated sides were significantly different at all testing times, as expected. There was no difference in the incidence of adverse effects or patient satisfaction scores between the Whitacre and the Quincke groups. Unilateral spinal block for outpatient surgery can be achieved with both pencil-point (Whitacre) and Quincke needles using 6.0 mg of plain bupivacaine. Neither the spread of sensory and motor blocks nor the corresponding recovery times appeared to be different between the groups. Nor was there any difference in patient satisfaction.

Hyposmia, the decreased sense of smell, and anosmia, the loss of sense of smell, may be unilateral or bilateral. If the olfactory acuity examined by means of bilateral test is normal, olfactory disorders are not found; unilateral examination is therefore necessary for definite evaluation of olfactory acuity. As evidence, 7 cases out of 94 patients with chronic rhinosinusitis and 6 cases out of 12 patients who received the surgery of anterior cranial fossa showed definite different olfactory threshold between nasal cavities, and there were no patients who recognized the diminished sense of smell in spite of unilateral high olfactory threshold. Additionally, we have experienced that a patient with brain tumor was diagnosed by the help of unilateral olfactory test. We thus strongly recommend the unilateral olfactometry as a method for simple and reliable test in clinical measurement of the sense of smell.

This study aimed to determine the impact of cochlear implantation on speech understanding in noise, subjective perception of hearing, and tinnitus perception of adult patients with unilateral severe to profound hearing loss and to investigate whether duration of deafness and age at implantation would influence the outcomes. In addition, this article describes the auditory training protocol used for unilaterally deaf patients. This is a prospective study of subjects undergoing cochlear implantation for unilateral deafness with or without associated tinnitus. Speech perception in noise was tested using the Bamford-Kowal-Bench speech-in-noise test presented at 65 dB SPL. The Speech, Spatial, and Qualities of Hearing Scale and the Abbreviated Profile of Hearing Aid Benefit were used to evaluate the subjective perception of hearing with a cochlear implant and quality of life. Tinnitus disturbance was measured using the Tinnitus Reaction Questionnaire. Data were collected before cochlear implantation and 3, 6, 12, and 24 months after implantation. Twenty-eight postlingual unilaterally deaf adults with or without tinnitus were implanted. There was a significant improvement in speech perception in noise across time in all spatial configurations. There was an overall significant improvement on the subjective perception of hearing and quality of life. Tinnitus disturbance reduced significantly across time. Age at implantation and duration of deafness did not influence the outcomes significantly. Cochlear implantation provided significant improvement in speech understanding in challenging situations, subjective perception of hearing performance, and quality of life. Cochlear implantation also resulted in reduced tinnitus disturbance. Age at implantation and duration of deafness did not seem to influence the outcomes.

An instance of isolated unilateral temporalis muscle hypertrophy (reactive masticatory muscle hypertrophy with fiber type 1 predominance) confirmed by muscle biopsy with histochemical fiber typing and image analysis in a 62 year-old man is reported. The patient presented with bruxism and a painful swelling of the temple. Absence of asymmetry or other abnormalities of the craniofacial skeleton was confirmed by magnetic resonance imaging and cephalometric analyses. The patient achieved symptomatic improvement only after undergoing botulinum toxin injections. Muscle biopsy is key in the diagnosis of reactive masticatory muscle hypertrophy and its distinction from masticatory muscle myopathy (hypertrophic branchial myopathy) and other non-reactive causes of painful asymmetric temporalis muscle enlargement.

Transforaminal and interlaminar epidural steroid injections are commonly used interventional pain management procedures in the treatment of radicular low back pain. Even though several studies have shown that transforaminal injections provide enhanced short-term outcomes in patients with radicular and low back pain, they have also been associated with a higher incidence of unintentional intravascular injection and often dire consequences than have interlaminar injections. We compared 2 different approaches, midline and lateral parasagittal, of lumbar interlaminar epidural steroid injection (LESI) in patients with unilateral lumbosacral radiculopathic pain. We also tested the role of concordant pressure paresthesia occurring during LESI as a prognostic factor in determining the efficacy of LESI. Prospective, randomized, blinded study. Pain management center, part of a teaching-community hospital in a major metropolitan US city. After Institutional Review Board approval, 106 patients undergoing LESI for radicular low back pain were randomly assigned to one of 2 groups (53 patients each) based on approach: midline interlaminar (MIL) and lateral parasagittal interlaminar (PIL). Patients were asked to grade any pressure paresthesia as occurring ipsilaterally or contralaterally to their "usual and customary pain," or in a distribution atypical of their daily pain. Other variables such as: the Oswestry Disability Index questionnaire, pain scores at rest and during movement, use of pain medications, etc. were recorded 20 minutes before the procedure, and on days 1, 7, 14, 21, 28, 60, 120, 180 and 365 after the injection. Results of this study showed statistically and clinically significant pain relief in patients undergoing LESI by both the MIL and PIL approaches. Patients receiving LESI using the lateral parasagittal approach had statistically and clinically longer pain relief then patients receiving LESI via a midline approach. They also had slightly better quality of

To compare the effect of, and the rate of subsequent development of iatrogenic antielevation syndrome after, unilateral versus bilateral inferior oblique graded recession-anteriorization to treat unilateral inferior oblique overaction. Thirty-four patients with unilateral inferior oblique overaction were included in a randomized prospective study. Patients were equally divided into 2 groups. Group UNI underwent unilateral, group BI bilateral, inferior oblique graded recession-anteriorization. A successful outcome was defined as orthotropia, or within 2 ∆ of a residual hypertropia, in the absence of signs of antielevation syndrome, residual inferior oblique overaction, V-pattern, dissociated vertical deviation, or ocular torticollis. A successful outcome was achieved in 11 (64.7%) and 13 (76.5%) patients in groups UNI and BI, respectively (p = 0.452). Antielevation syndrome was diagnosed as the cause of surgical failure in 6 (35.3%) and 2 (11.8%) patients, in groups UNI and BI, respectively (p = 0.106). The cause of surgical failure in the other 2 patients in group BI was due to persistence of ocular torticollis and hypertropia in a patient with superior oblique palsy and a residual V-pattern and hypertropia in the other patient. The differences between unilateral and bilateral inferior oblique graded recession-anteriorization are insignificant. Unilateral surgery has a higher tendency for the subsequent development of antielevation syndrome. Bilateral surgery may still become complicated by antielevation syndrome, although at a lower rate. In addition, bilateral surgery had a higher rate of undercorrection. Further studies on a larger sample are encouraged.

Minor events that occur in the workplace sometimes are evaluated with MRI, which may reveal age-related changes in the symptomatic body part. These age-related changes are often ascribed to the event. However, evidence of similar or worse pathophysiology in the contralateral joint would suggest that the symptoms might be new, but the pathophysiology is not. Using a convenience sample of occupational injury claimants with bilateral MRI to evaluate unilateral knee or shoulder symptoms ascribed to a single event at work, we sought to determine whether MRI findings of the shoulder and knee are more often congruent or incongruent with new unilateral symptoms. Two hundred ninety-four occupational injury claimants employed at companies throughout Texas that do not subscribe to workers' compensation insurance, who were older than 40 years, and with unilateral shoulder or knee symptoms, were studied. Starting in 2012, all patients seen by OccMD Group PA who present with unilateral symptoms ascribed to work undergo bilateral MRI, based on several previous occasions where bilateral MRI proved to be a compelling demonstration that perceived injuries are more likely age-related, previously well-adapted pathophysiology. MRI findings (anything described as abnormal by the radiologist; eg, defect size or signal change) was considered congruent if the abnormality of one or more structures on the symptomatic side was greater than that of the corresponding structures in the asymptomatic joint. Bivariate analysis was used to compare the frequency of MRI findings congruent and incongruent with symptoms. Logistic regression was used to evaluate factors associated with MRI findings of the shoulder or knee. Less than half of the patients with shoulder (90 of 189; 48%; p = 0.36) or knee (45 of 105; 43%; p = 0.038) symptoms had worse pathologic features on the symptomatic side. Older age was associated with disorders in the infraspinatus tendon (59 ± 8 versus 56 ± 8 years; p = 0

Collateral pathways are important in maintaining adequate cerebral blood flow in patients with carotid stenosis. We aimed to evaluate the hemodynamic patterns in relation to carotid stenosis in acute stroke patients. Consecutive 586 stroke patients in a hospital based cohort were included in the present study. Carotid duplex was performed to identify patients with absolute minimal diameter reductions of 50% or greater in their internal carotid arteries (ICAs). Color velocity imaging quantification ultrasound (CVIQ) was used to measure extracranial arterial blood flow volume (BFV) in bilateral common carotid arteries (CCAs) and bilateral vertebral arteries (VAs). The absolute values of BFV and the ratios were compared between patients with and without ICA stenosis. Among 586 acute ischemic stroke patients (mean age: 67.5 ± 12.4y), ICA stenosis was detected in 112 patients (19.1%), including unilateral ICA stenosis in 81 patients (13.8%) and bilateral ICA stenosis in 31 patients (5.3%). Among patients with unilateral ICA stenosis, the BFV in contralateral CCA was significantly higher than that in ipsilateral CCA (325.5 ± 99.8 mL/min vs. 242.2 ± 112.2 mL/min, P < 0.001). Among patients with bilateral ICA stenosis, the sum of BFV in bilateral VAs accounted for 22% of the whole cerebral blood flow, which was significantly higher than that in those without ICA stenosis (14.8%, P < 0.001) or with unilateral ICA stenosis (16.9%, P = 0.007). In patients with unilateral carotid stenosis, contralateral carotid blood flow increases to compensate decreased blood flow, while posterior circulation may compensate for the decreased brain perfusion in those with bilateral carotid stenosis.

Although multimodal pain management including periarticular multidrug injection can provide excellent pain relief in the early postoperative period after total knee arthroplasty (TKA), rebounding pain remains an important challenge. A randomized, double-blind, placebo-controlled trial was performed to investigate the efficacy of adding intravenous acetaminophen to multimodal pain management for TKA. We enrolled 67 patients scheduled for unilateral TKA. Patients were randomly assigned to receive either 1000 mg of intravenous acetaminophen at 6-hour intervals or normal saline at the same intervals. All patients were treated with intraoperative periarticular multidrug injection and intravenous and oral nonsteroidal anti-inflammatory drugs. The primary outcome was the postoperative 100-mm visual analog pain scale at the time of administration of study drugs. In the intention-to-treat analysis, the pain score was significantly better in the intravenous acetaminophen group than the placebo group at 17:00 one day after TKA (15.3 ± 17.0 mm vs 26.8 ± 19.0 mm; P = .013). There were no significant differences in terms of the rate of complications between groups. Even in the setting of multimodal pain management including periarticular multidrug injection, intravenous acetaminophen provided better pain relief for patients undergoing unilateral TKA.

To investigate the effect of virtual reality training on unilateral spatial neglect in stroke patients. Twenty-four stroke patients (14 males and 10 females, mean age=64.7) who had unilateral spatial neglect as a result of right hemisphere stroke were recruited. All patients were randomly assigned to either the virtual reality (VR) group (n=12) or the control group (n=12). The VR group received VR training, which stimulated the left side of their bodies. The control group received conventional neglect therapy such as visual scanning training. Both groups received therapy for 30 minutes a day, five days per week for three weeks. Outcome measurements included star cancellation test, line bisection test, Catherine Bergego scale (CBS), and the Korean version of modified Barthel index (K-MBI). These measurements were taken before and after treatment. There were no significant differences in the baseline characteristics and initial values between the two groups. The changes in star cancellation test results and CBS in the VR group were significantly higher than those of the control group after treatment. The changes in line bisection test score and the K-MBI in the VR group were not statistically significant. This study suggests that virtual reality training may be a beneficial therapeutic technique on unilateral spatial neglect in stroke patients.

Background and purpose — There is no consensus about the outcome of simultaneous vs. staged bilateral total knee arthroplasty (TKA). We examined this issue by analyzing 238,373 patients. Patients and methods — Demographic, clinical, and outcome data were evaluated for TKA patients (unilateral: 206,771; simultaneous bilateral: 6,349; staged bilateral: 25,253) from the Canadian Hospital Morbidity Database for fiscal years 2006–2007 to 2012–2013. Outcomes were adjusted for age, sex, comorbidities, and hospital TKA volume. Results — Simultaneous bilateral TKA patients were younger than staged bilateral TKA patients (median 64 years vs. 66 years), were more likely to be male (41% vs. 39%), and had a lower frequency of having ≥1 comorbid condition (2.9% vs. 4.2%). They also had a higher frequency of blood transfusions (41% vs. 19%), a shorter median length of stay (6 days vs. 8 days), a higher frequency of transfer to a rehabilitation facility (46% vs. 9%), and a lower frequency of knee infection (0.5% vs. 0.9%) than staged bilateral TKA patients, but they had higher rate of cardiac complications within 90 days (2.0% vs. 1.7%). Simultaneous patients had higher in-hospital mortality compared to the second TKA in staged patients (0.16% vs. 0.06%), but they had similar rates of in-hospital mortality compared to unilateral patients (0.16% vs. 0.14%). The cumulative 3-year revision rate was highest in the unilateral group (2.3%), but it was similar in the staged and simultaneous bilateral groups (1.4%). Interpretation — We found important differences between the outcomes of simultaneous and staged bilateral TKA. Further clarification of outcomes would be best determined in an adequately powered randomized trial, which would remove the selection bias inherent in this retrospective study design. PMID:27167849

The most widely used surgical interventions for pediatric unilateral vocal cord paralysis include injection laryngoplasty, thyroplasty, and laryngeal reinnervation. Despite increasing interest in surgical interventions for unilateral vocal cord paralysis in children, the surgical outcomes data in children are scarce. To appraise and summarize the available evidence for pediatric unilateral vocal cord paralysis surgical strategies. MEDLINE (1946-2014) and EMBASE (1980-2014) were searched for publications that described the results of laryngoplasty, thyroplasty, or laryngeal reinnervation for pediatric unilateral vocal cord paralysis. Further studies were identified from bibliographies of relevant studies, gray literature, and annual scientific assemblies. Two reviewers independently appraised the selected studies for quality, level of evidence, and risk of bias as well as extracted data, including unilateral vocal cord paralysis origin, voice outcomes, swallowing outcomes, and adverse events. Of 366 identified studies, the inclusion criteria were met by 15 studies: 6 observational studies, 6 case series, and 3 case reports. All 36 children undergoing laryngeal reinnervation (8 studies) had improvement or resolution of dysphonia. Of 31 children receiving injection laryngoplasty (6 studies), most experienced improvement in voice quality, speech, swallowing, aspiration, and glottic closure. Of 12 children treated by thyroplasty (5 studies), 2 experienced resolution of dysphonia, 4 had some improvement, and 4 had no improvement (2 patients had undocumented outcomes). Thyroplasty resolved or improved aspiration in 7 of 8 patients. Published studies suggest that reinnervation may be the most effective surgical intervention for children with dysphonia; however, long-term follow-up data are lacking. With the exception of polytetrafluoroethylene injections, injection laryngoplasty was reported to be a relatively safe, nonpermanent, and effective option for most children with

AIM This study compared the responses between patients with unilateral sciatica and pain-free volunteers following administration of intradermal capsaicin. METHODS Fourteen patients with unilateral sciatica and 12 pain-free volunteers received one injection per hour over 4 h of 1 µg and 10 µg capsaicin, into each calf. For each dose, spontaneous pain (10 cm VAS), area of flare (cm2) and the sum of allodynia and hyperalgesia radii across eight axes (cm) were recorded pre-injection and at 5, 15, 30, 45 and 60 min post injection. RESULTS Sciatica subjects experienced higher spontaneous pain and hyperalgesia responses in both legs compared with pain-free volunteers. The largest mean difference in spontaneous pain was 2.8 cm (95% CI 1.6, 3.9) at 5 min in the unaffected leg following 10 µg. The largest mean difference in hyperalgesia was 19.7 cm (95% CI 12.4, 27.0) at 60 min in the unaffected leg following 10 µg. Allodynia was greater in patients than in controls with the largest mean difference of 2.9 cm (95% CI 1, 4.8) at 5 min following 10 µg in the affected leg. Allodynia was also higher in the affected leg compared with the unaffected leg in sciatica patients with the highest mean difference of 3.0 cm (95% CI 1.2, 4.7) at 5 min following 10 µg. CONCLUSIONS The responses to intradermal capsaicin are quantitatively and qualitatively different in unilateral sciatica patients compared with pain-free controls. PMID:21740458

To investigate whether listening to pleasant music improves visual attention to and awareness of contralesional stimuli in patients with unilateral neglect after stroke. A within-subject design was used with 19 participants with unilateral neglect following a right hemisphere stroke. Participants were tested in three conditions (pleasant music, unpleasant music and white noise) within 1 week. All musical pieces were chosen by the participants. In each condition, participants were asked to complete three sub-tests of the Behavioural Inattention Test (the Star Cancellation Test, the Line Bisection Test and the Picture Scanning test) and a visual exploration task with everyday scenes. Eye movements in the visual exploration task were recorded simultaneously. Mood and arousal induced by different auditory stimuli were assessed using visual analogue scales, heart rate and galvanic skin response. Compared with unpleasant music and white noise, participants rated their moods as more positive and arousal as higher with pleasant music, but also showed significant improvement on all tasks and eye movement data, except the Line Bisection Test. The findings suggest that pleasant music can improve visual attention in patients with unilateral neglect after stroke. Additional research using randomized controlled trials is required to validate these findings.

The bilateral and unilateral interlaminar techniques for bilateral decompression both demonstrate good results for the treatment of degenerative lumbar spinal stenosis (DLSS). Although there is some discussion about which approach is more effective, studies that directly compare these two popular techniques are rare. To address this shortcoming, this study compares postoperative functional disability, pain, and patient satisfaction among patients with single-level DLSS who underwent bilateral decompression using either a bilateral or unilateral approach. This retrospective study included patients who underwent operations between November 1, 2009, and October 1, 2011. These patients underwent single-level bilateral decompressive surgery using either the bilateral or unilateral interlaminar approach at one of 5 participating hospitals. Exclusion criteria included previous lumbar surgery, additional disc surgery, and spondylolisthesis requiring fusion surgery. Primary outcome measures included bodily pain (as reported using the visual analog scale [VAS]), the Roland-Morris Disability Questionnaire (RMDQ), and the Oswestry Disability Index (ODI). In addition, reductions in leg and back symptoms and the patient's general evaluation of the procedure were queried. Finally, patient satisfaction and surgical parameters were evaluated. Questionnaires were sent to each patient's home, and electronic patient files were used to collect the data. One hundred and seventy-five patients returned the questionnaire (74.4% response rate; 68 and 107 patients who underwent the bilateral or unilateral approach, respectively). Mean age at surgery was 68 years (range 34-89 years), and the mean follow-up period was 14.2 months (range 3.3-27.4 years). There were no significant differences in ODI (20.3 vs 22.6 for the bilateral and unilateral approaches, respectively), RMDQ (3.99 vs 4.8, respectively), or pain scores between treatment groups. Back symptoms were reduced in 74.8% (bilateral: 74

Objective To compare the gait of adults with unilateral and bilateral symptomatic and radiographic knee osteoarthritis (OA) to determine whether these subgroups can be treated similarly in the clinic and when recruiting for randomized clinical trials, and to use these data to generate future hypotheses regarding gait in these subsets of knee OA patients. Methods Cross-sectional investigation of patients with unilateral and bilateral knee OA on gait mechanics using 136 older adults (age ≥ 55 yrs.; 27 kg.m−2 ≥ BMI ≤ 41 kg.m−2; 82% female) with radiographic knee OA. Comparisons were made between the most affected side of the bilateral group (Bi) and the affected side of the unilateral group (Uni), and between symmetry indices of each group. Results There were no significant differences in any temporal, kinematic, or kinetic measures between the Uni and Bi cohorts. Comparison of symmetry indices between groups also revealed no significant differences. Conclusion The similarity in lower extremity mechanics between unilateral and bilateral knee OA patients is sufficiently robust to consider both subsets as a single cohort. We hypothesize that biomechanical adaptations to knee OA are at least partially systemic in origin and not based solely on the physiological characteristics of an affected knee joint. PMID:26706699

Abstract The aim of the study was to assess the capacity of dynamic cerebral autoregulation (dCA) in asymptomatic patients with unilateral middle cerebral artery (MCA) stenosis. Fifty-seven patients with asymptomatic mild, moderate, and severe unilateral MCA stenosis and 8 patients with symptomatic severe unilateral MCA stenosis diagnosed by transcranial Doppler were enrolled. Twenty-four healthy volunteers served as controls. The noninvasive continuous cerebral blood flow velocity and arterial blood pressure were recorded simultaneously from each subject in the supine position. Transfer function analysis was applied to determine the autoregulatory parameters (phase difference [PD] and gain). The PD values in the severe stenosis groups were significantly lower than those of the control group (60.71 ± 18.63°), the asymptomatic severe stenosis group was impaired ipsilaterally (28.94 ± 27.43°, P < 0.001), and the symptomatic severe stenosis group was impaired bilaterally (13.74 ± 19.21°, P < 0.001; 19.68 ± 14.50°, P = 0.006, respectively). The PD values in the mild and moderate stenosis groups were not significantly different than the controls (44.49 ± 27.93°; 48.65 ± 25.49°, respectively). The gain values in the mild and moderate groups were higher than in the controls (1.00 ± 0.58 cm/s/mm Hg vs 0.86 ± 0.34 cm/s/mm Hg, and 1.20 ± 0.59 cm/s/mm Hg vs 0.86 ± 0.34 cm/s/mm Hg, respectively). The gain values in the severe stenosis groups were significantly lower than that in the control group: the asymptomatic severe stenosis group was lower bilaterally (0.56 ± 0.32 cm/s/mm Hg, P = 0.003; 0.60 ± 0.32 cm/s/mm Hg, P < 0.05, respectively), whereas the symptomatic severe group was lower unilaterally (on the contralateral side) (0.53 ± 0.43 cm/s/mm Hg, P < 0.05). In asymptomatic patients with unilateral MCA stenosis, only the dCA of the severe stenosis was ipsilaterally

A patient presented with unilateral findings of night blindness shown by impaired rod function and dark adaptation, constricted visual fields with good central acuity, a barely recordable electro-retinographic b-wave, and a unilaterally impaired electro-oculogram. There were none of the pigmentary changes usually associated with retinitis pigmentosa. The unaffected right eye was normal in all respects. Therefore the case is most probably one of unilateral retinitis pigmentosa sine pigmento.

The changes in line bisection test score and the K-MBI in the VR group were not statistically significant. Conclusion This study suggests that virtual reality training may be a beneficial therapeutic technique on unilateral spatial neglect in stroke patients. PMID:22506138

The CLECOS_P system was conceived for registering and automating the processing of clinical evaluations performed on patients with Parkinson's disease who undergo functional neurosurgery and/or neural transplant. CLECOS_P represents the first time a computerized system is able to offer--with high precision and considerable time-savings--an integral analysis of the evolutive behavior of the universe in integrated variables at the core assessment program for intracerebral transplantations (CAPIT). CAPIT is used internationally for the evaluation and follow-up of patients with this pathology who have undergone neural transplant. We used the so-called MEDSAC methodology for the preparation of this system. The methodology that was used for the design of an intelligent system aimed at medical decision-making was based on the quantitative analysis of the clinical evolution. At the present moment, there are 20 patients controlled by this system: 11 bilaterally transplanted, 9 unilaterally (registered in ranks of 3 months before operation up to 1, 2, 3, 6, 9, 12, 18, and 24 months after operation). The application of CLECOS_P to these patients permitted the evaluation of 400 clinical variables, where a better evolutive characterization of the patients was obtained, thus getting most favorable results with personalized therapeutic methods aimed at raising their quality of life. CLECOS_P is used in a multi-user environment on a local area network running Novell Netware version 3.11.

The study aims to determine body weight ratios between extremities in patients with unilateral total knee arthroplasty (TKA) at 12 months postoperatively at the static-standing position at 30, 60 and 90 degrees of knee flexion. The study included 52 female patients (mean age 65.6±10.6 years; range 40 to 83 years) who underwent unilateral primary TKA. The force-platform was used to calculate the body-weight ratios of the patients. Body weight ratios on the operated and non-operated limbs of the unilateral TKA patients were examined at standing-static position at 30, 60 and 90 degrees of knee flexion on the force-platform according to their age and body mass index (BMI). The pain levels of the patients were evaluated using the visual analog scale. It was found that unilateral TKA patients placed their body weight on the non-operated limb more at the standing-static position, and 30, 60 and 90 degrees of knee flexion at 12 months postoperatively (p<0.05). It was also found that as the knee flexion degree increased with age, so did TKA patients place their body weight on the nonoperated limb more (p<0.05), and that BMI had no effect on the load distribution difference over the two extremities (p>0.05). During the postoperative period, load asymmetry between the two extremities in patients with unilateral TKA remains the same due to advancing age. This accelerates the osteoarthritis process on the non-operated knee. It is concluded that the age factor should be taken into account while planning physiotherapy and rehabilitation programs for unilateral TKA patients and knee exercise programs aiming to place load over the operated limb should be arranged.

Our objective was to compare the presence of self-reported unilateral photophobia or phonophobia, or both, during headache attacks comparing patients with trigeminal autonomic cephalalgias (TACs)--including cluster headache, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and paroxysmal hemicrania--or hemicrania continua, and other headache types. We conducted a prospective study in patients attending a referral out-patient clinic over 5 months and those admitted for an intramuscular indomethacin test. Two hundred and six patients were included. In episodic migraine patients, two of 54 (4%) reported unilateral photophobia or phonophobia, or both. In chronic migraine patients, six of 48 (13%) complained of unilateral photophobia or phonophobia, or both, whereas none of the 24 patients with medication-overuse headache reported these unilateral symptoms, although these patients all had clinical symptoms suggesting the diagnosis of migraine. Only three of 22 patients (14%) suffering from new daily persistent headache (NDPH) experienced unilateral photophobia or phonophobia. In chronic cluster headache 10 of 21 patients (48%) had unilateral photophobia or phonophobia, or both, and this symptom appeared in four of five patients (80%) with episodic cluster headache. Unilateral photophobia or phonophobia, or both, were reported by six of 11 patients (55%) with hemicrania continua, five of nine (56%) with SUNCT, and four of six (67%) with chronic paroxysmal hemicrania. Unilateral phonophobia or photophobia, or both, are more frequent in TACs and hemicrania continua than in migraine and NDPH. The presence of these unilateral symptoms may be clinically useful in the differential diagnosis of primary headaches.

A patient presented with unilateral findings of night blindness shown by impaired rod function and dark adaptation, constricted visual fields with good central acuity, a barely recordable electro-retinographic b-wave, and a unilaterally impaired electro-oculogram. There were none of the pigmentary changes usually associated with retinitis pigmentosa. The unaffected right eye was normal in all respects. Therefore the case is most probably one of unilateral retinitis pigmentosa sine pigmento. Images PMID:952804

Comparison of characteristics observed in tinnitus patients with unilateral vs bilateral symptoms, with both normal hearing threshold and distortion-product otoacoustic emissions.

Tinnitus characteristics in normal-hearing patients differ between the groups with unilateral and bilateral complaints. The study was to determine the differences between tinnitus characteristics observed in patients with unilateral vs bilateral symptoms and normal hearing threshold, as well as normal results of distortion-product otoacoustic emissions (DPOAEs). The patients answered questions concerning tinnitus duration, laterality, character, accompanying symptoms, and circumstances of onset. The results of tympanometry, auditory brainstem responses, tinnitus likeness spectrum, minimum masking level (MML), and uncomfortable loudness level were evaluated. Records of 380 tinnitus sufferers were examined. Patients with abnormal audiograms and/or DPOAEs were excluded. The remaining 66 participants were divided into groups with unilateral and bilateral tinnitus. Unilateral tinnitus in normal-hearing patients was diagnosed twice more frequently than bilateral. Tinnitus pitch was higher in the group with bilateral tinnitus (p < .001). MML was lower in unilateral tinnitus (p < .05). Mean age of patients was higher in the unilateral tinnitus group (p < .05). Mean tinnitus duration was longer (p < .05) and hypersensitivity to sound was more frequent (p < .05) in the bilateral tinnitus group. Repeated exposure to excessive noise was the most frequent cause in the bilateral tinnitus group.

Presurgical nasoalveolar molding (PNAM) is controversial in maxillofacial orthopedics. It supposedly improves the nasal esthetics and function in unilateral cleft lip/palate (UCLP) patients. However, there is no research available in South America to support this claim. The purpose of this study was to evaluate the efficacy of presurgical nasoalveolar molding therapy on morphological changes of the noses of unilateral cleft lip/palate patients in a Colombian sample. Seventeen neonate UCLP patients using PNAM received facial impressions at the beginning of treatment; before primary rhinocheiloplasty; and before palatoplasty. A submentovertex photograph of each cast was taken and analyzed by digital photogrammetry. Wilcoxon and Friedman tests were used for within- and between-group comparisons. A statistically significant reduction of cleft nostril width, without significant changes in noncleft nostril width or total nasal width, was found after PNAM. A significant increase in cleft and noncleft nostril height, plus a nonsignificant increase in nostril area in both sides and a nonsignificant uprighting of the columella were found. These changes were maintained or further improved after rhinocheiloplasty. The presurgical nasoalveolar molding technique improved nasal tip projection and alar cartilage depression and decreased partially columella deviation before rhinocheiloplasty in South American unilateral cleft lip/palate patients.

No study has previously analyzed pressure pain sensitivity of nerve trunks in migraine. This study aimed to examine the differences in mechanical pain sensitivity over specific nerves between patients with unilateral migraine and healthy controls. Blinded investigators assessed pressure pain thresholds (PPT) over the supra-orbital nerves (V1) and peripheral nerve trunks of both upper extremities (median, radial, and ulnar nerves) in 20 patients with strictly unilateral migraine and 20 healthy matched controls. Pain intensity after palpation over both supra-orbital nerves was also assessed. A pressure algometer was used to quantify PPT, whereas a 10-point numerical pain rate scale was used to evaluate pain to palpation over the supra-orbital nerve. The analysis of covariance revealed that pain to palpation over the supra-orbital nerve was significantly higher (P<0.001) on the symptomatic side (mean: 3.4, SD: 1.5) as compared with the nonsymptomatic side (mean: 0.5, SD: 1.2) in patients with migraine and both the dominant (mean: 0.2, SD: 0.4) and nondominant (mean: 0.3, SD: 0.5) sides in healthy controls. PPT assessed over the supra-orbital nerve on the symptomatic side (mean: 1.05, SD: 0.2 kg/cm) was significantly lower (P<0.05) than PPT measurements on the nonsymptomatic side (mean: 1.35, SD: 0.3 kg/cm) and either the dominant (mean: 1.9, SD: 0.2 kg/cm) or nondominant (mean: 1.9, SD: 0.3 kg/cm) sides in controls (P<0.001). Finally, PPT assessed over the median, ulnar, and radial nerves were significantly lower in patients with migraine as compared with controls (P<0.001), without side-to-side differences (P>0.6). In patients with unilateral migraine, we found increased mechano-sensitivity of the supra-orbital nerve on the symptomatic side of the head. Outside the head, the same patients showed increased mechano-sensitivity of the main peripheral nerves of both upper limbs, without asymmetries. Such diffuse hypersensitivity of the peripheral nerves lends further

Facial asymmetries due to unilateral condylar hyperactivity are often a challenge both for maxillo-facial surgeons and for orthodontists; the current literature shows different opinions about aetiology, classification, treatment approach and timing. We made a retrospective study on patients suffering from unilateral condylar hyperactivity between 1997 and 2015 in our Department; clinical features and treatment options were grouped and compared with literature. The descriptive analysis investigated variables like sex, age, side and direction of the asymmetry, condylar activity and type of intervention. The population was composed of 128 patients. The hemimandibular hyperactivity occurs equally in both sexes around the second decade, although the range of the first consultation goes from 7 to 49 y.o. The vertical hyperdevelopment group is almost equal to the horizontal. All the patients with horizontal hyperactivity showed negative scintigraphy and were treated with pre-surgical orthodontics and orthognathic surgery; patients with vertical hyperactivity and positive scintigraphy were treated with condylectomy and post-surgical orthodontics. In our group of patients, direction of the hyperactivity and results of the scintigraphy lead to treatment choice and timing. Further studies are necessary to explain why, in our group, all the patients with horizontal involvement are negative to scintigraphy.

2018-01-01

A 'wait and see' strategy is an option when managing patients with small vestibular schwannomas (VS). A risk of growth and worsening of hearing may influence a patient's daily quality of life (QOL). Therefore, the present study focused on QOL parameters in patients who are on a 'wait and see' strategy following magnetic resonance imaging (MRI)-based diagnosis of small unilateral VS. Sixty-five patients (mean age 64.4 years; male:female, 32:33) who suffered from a small unilateral VS (9.34 mm, range 1.5-23 mm) between 2013 and 2016 were included in a prospective single center study. During follow-up, in addition to clinical and neurological examinations and MRI imaging, all patients answered the Short Form 36 questionnaire once to characterize QOL. Additionally, the severity of tinnitus was determined by the Mini-TQ-12 from Hiller and Goebel. It was found during follow-up that there was no lowering of QOL in patients with small VS who were on 'wait and see' strategy compared with Germany's general population and no tumor growth was detected in 53 patients (81.5%). Patients with a tumor diameter larger than 10 mm did not suffer from stronger tinnitus, vertigo or unsteadiness than the group with an average tumor size, which is smaller than 10 mm. Sixty-two patients (95.4%) showed ipsilateral hearing loss and three of these reported deafness (4.6%). Severe vertigo or tinnitus is connected with lower levels of mental component scale and physical component scale. These findings reduced the QOL (p = 0.05). In our series, QOL is not influenced in patients with unilateral untreated small VS in comparison to Germany's general population. This is helpful information when advising patients during follow-up and finding out the optimal timing of individual treatment.

Using Aminocaproic Acid to Reduce Blood Loss After Primary Unilateral Total Knee Arthroplasty.

Churchill, Jessica L; Toney, Victor A; Truchan, Susan; Anderson, Michael J

2016-01-01

xtensive blood loss after total knee arthroplasty (TKA) is common, and affected patients often require blood transfusions. Studies suggest that antifibrinolytic agents such as aminocaproic acid (ACA) reduce blood loss and blood transfusion rates in patients undergoing TKA. We conducted a study to evaluate whether a single intravenous 10-g dose of ACA given during primary unilateral TKA would decrease perioperative blood loss, raise postoperative hemoglobin levels, and reduce postoperative blood transfusion rates. We retrospectively reviewed the charts of 50 comparable cemented primary unilateral TKAs. Twenty-five patients had been given a single intraoperative 10-g dose of ACA (antifibrinolytic group), and the other 25 had not been given ACA (control group). Postoperative drain output was decreased significantly (P < .0001) in the antifibrinolytic group (155 mL) compared with the control group (410 mL), as was the number of units of blood transfused after surgery (antifibrinolytic group, 0 units; control group, 10 units; P < .002). There were no adverse events in the antifibrinolytic group. In TKA, perioperative blood loss and blood transfusion rates were reduced significantly in patients given a single intraoperative intravenous 10-g dose of ACA compared with patients not given antifibrinolytics. The positive effects of ACA were obtained without adverse events or complications.

This study compares the symptoms, disabilities and handicap, as assessed by means of a questionnaire, in two groups of patients with a unilateral peripheral vestibular disorder: those with a total canal paresis and those with a partial canal paresis, as judged by the duration parameter using the Fitzgerald Hallpike caloric test in the absence of optic fixation. The results of the study indicate that the severity of dizziness, the Dizziness Index (severity x frequency) and the overall level of disabilities related to visual vertigo are less severe in unilateral profound or total loss of vestibular function than in unilateral mild vestibular loss.

Abstract Anophthalmia is a rare ocular malformation. It is a genetically determined disorder and is typically associated with syndromes. However, sporadic nonsyndromic familial as well as non-familial cases of anophthalmia have also been reported. Non-syndromic familial cases are usually bilateral and have been attributed to autosomal recessive, autosomal dominant, and X-linked inheritance patterns. The authors hereby report a rare case of autosomal recessive unilateral anophthalmia in a patient with no other associated congenital anomaly. Patient was operated for craniopharyngioma. The clinical, radiological and intraoperative findings are discussed. PMID:27928292

Patients with unilateral neglect have problems reporting, responding, or orienting to novel or meaningful stimuli that is presented to the side opposite to that of a brain lesion. This creates a serous problem in regards to daily living activities. However, the established methods for assessing and training of unilateral neglect patients have several deficits. Recently, virtual reality (VR) technologies have been used as an assessment and treatment tool for rehabilitation. Hence, this study designed a VR system to assess and train unilateral neglect patients. In addition, the suitability and feasibility of our VR system for unilateral neglect patients was verified.

To evaluate the sciatic nerves of patients with unilateral sciatica by using an ultrasound, and to determine whether ultrasonographic findings were related to clinical and electrophysiologic parameters. Cross-sectional study. Physical medicine and rehabilitation departments of a university hospital and a rehabilitation hospital. Consecutive patients (N=30; 10 men, 20 women) with complaints of low back pain and unilateral sciatica of more than 1 month of duration were enrolled. Not applicable. All patients underwent a substantial clinical assessment, and they were also evaluated by electromyogram and magnetic resonance imaging. Pain was evaluated by a visual analog scale and the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Scale. A linear array probe (7.5-12MHz) was used to scan sciatic nerves bilaterally in the prone position. Sciatic nerve diameters-thickness (short axis) and width (long axis)-and cross-sectional areas were measured bilaterally at the same levels, proximal to the bifurcation and midthigh. The values pertaining to the unaffected limbs were taken as controls. When compared with the unaffected sides, mean values for sciatic nerve measurements-long axis at bifurcation level (P=.017) and cross-sectional area at midthigh level (P=.005)-were significantly larger on the affected sides. Swelling ratios negatively correlated with symptom duration (r=-.394, P=.038) and LANSS scores (r=-.451, P=.016) at only midthigh level. Sciatic nerves seem to be enlarged on the side of sciatica in patients with low back pain. Our preliminary results may provide insight into better understanding the lower limb radiating pain in this group of patients. Copyright © 2012 American Congress of Rehabilitation Medicine.

To determine the demographic characteristics of patients undergoing primary total knee arthroplasty during the years 1989, 1999, and 2009 at our institution and determine whether their characteristics mirror the changing US demographic characteristics. Retrospective chart review of patients and prospective survey of experienced anesthesia providers in total knee arthroplasty. Tertiary care academic medical center. All patients 18 years and older who underwent unilateral primary total knee arthroplasty in 1989, 1999, and 2009 were identified through the Mayo Clinic Total Joint Registry. For each year, 200 patients were randomly selected. The demographic characteristics, comorbidities, perioperative care, and postoperative outcomes of patients, as well as survey responses from experienced anesthesia providers. During the 3 study years, a total of 591 patients were included for analysis. A statistically significant increase in body mass index (BMI) was observed over time in patients undergoing primary total knee arthroplasty (average BMI, 29.01 in 1989, 31.32 in 1999, and 32.32 in 2009 [P < .001]). Despite the increase in patient comorbidities, the percentage of patients who had postoperative complications decreased over time (P = .003), and postoperative disposition (general medicine ward vs intensive care unit) did not change. Our provider survey received a 76% response rate. In total, 82% of anesthesia providers who responded to the survey perceived that both BMI and the number of comorbidities had increased. Of survey respondents, 67% state that they have modified their perioperative anesthesia care because of changes in body habitus and patient comorbidities. The number of obese patients with comorbidities who present for total knee arthroplasty at our institution has increased over the past 20 years. Despite this fact, a reduction was detected in postoperative complications. Copyright © 2015 Elsevier Inc. All rights reserved.

The aim of this retrospective study was to assess the influence of presurgical nasoalveolar molding (NAM) on skeletal development in patients with operated unilateral cleft lip and palate at 5 years of age. Lateral cephalometric radiographs of 26 unilateral cleft lip and palate patients who had undergone presurgical NAM (NAM group) and 20 unilateral cleft lip and palate patients who did not have any presurgical NAM (non-NAM group) were analyzed. The radiographs were digitally traced using Quick Ceph Studio software (version 3.5.1.r (1151); Quick Ceph Systems, San Diego, Calif). Independent samples t tests were performed for statistical analysis. No significant differences were observed in sagittal and vertical skeletal measurements between the NAM and non-NAM groups. NAM resulted in no significant difference in skeletal development in unilateral cleft lip and palate patients compared with those without NAM in early childhood. Copyright © 2018.

Two unrelated prepubertal boys of ages 8 and 9 who presented with complaints of unilateral enlargement of breast tissue are reported. Physical examination, biochemical, hormonal and oncologic work-up findings were normal. Both patients were treated with peripheral liposuction successfully. Histopathological and immunohistochemical examinations showed benign fibroglandular gynecomastia and intensive (3+) estrogen receptor expression in 100% of periductal epithelial cells. Although an extremely rare and generally benign condition, patients with prepubertal unilateral gynecomastia should have a full endocrine and oncologic work-up.

Unilateral lung transplantation for pulmonary fibrosis.

PubMed

1986-05-01

Improvements in immunosuppression and surgical techniques have made unilateral lung transplantation feasible in selected patients with end-stage interstitial lung disease. We report two cases of successful unilateral lung transplantation for end-stage respiratory failure due to pulmonary fibrosis. The patients, both oxygen-dependent, had progressive disease refractory to all treatment, with an anticipated life expectancy of less than one year on the basis of the rate of progression of the disease. Both patients were discharged six weeks after transplantation and returned to normal life. They are alive and well at 26 months and 14 months after the procedure. Pulmonary-function studies have shown substantial improvement in their lung volumes and diffusing capacities. For both patients, arterial oxygen tension is now normal and there is no arterial oxygen desaturation with exercise. This experience shows that unilateral lung transplantation, for selected patients with end-stage interstitial lung disease, provides a good functional result. Moreover, it avoids the necessity for cardiac transplantation, as required by the combined heart-lung procedure, and permits the use of the donor heart for another recipient.

1993-04-01

We examined the relationship of preoperative unilateral memory function and quantitative hippocampal histology in patients undergoing anterior temporal lobectomy for the treatment of complex partial seizures. Recognition memory (objects, words, figures) was assessed preoperatively for each hemisphere by the intracarotid amobarbital procedure in 23 patients (mean age at the time of operation, 30.2 yr; standard deviation, 9.2; mean age at the time of seizure onset, 12.3 yr; standard deviation, 8.6) without tumor. Memory scores were the total number of items recognized, adjusted for guessing. Histological examination of the anterior 20 to 30 mm of hippocampal tissue was accomplished in all patients. The degree of unilateral memory impairment ipsilateral to the seizure focus was significantly correlated with decreased neuronal density in the hilar (r = 0.66, P < 0.001) and dentate granule (r = 0.61, P < 0.002) regions, but not in the CA1 (r = 0.10, P = not significant) or CA2-3 (r = 0.35, P = not significant) regions. Memory performance with the contralateral hemisphere was not significantly correlated with ipsilateral hippocampal densities. These data support the role of the hippocampus in human memory and show further evidence of hippocampal subfield specificity in the relationship between memory performance and neuronal cell loss. Further studies of the dentate granule and hilar regions in relation to human memory are warranted.

Thickness of the lower trapezius muscle in patients with neck pain has not been established. We examined the thickness of the lower trapezius muscle in patients with and without unilateral neck pain. Twenty women with unilateral (right) neck pain and 20 matched controls participated in the study. Thickness of the lower trapezius muscles was measured bilaterally at rest (0 ° and 120 ° of shoulder abduction) and during contraction (120 ° of shoulder abduction) using ultrasound imaging. The neck pain group had smaller thickness of the lower trapezius muscle on the painful side compared with controls both at rest and during contraction (P < 0.05). However, the percentage change in the lower trapezius thickness from rest to contraction (120 ° of shoulder abduction) was not different between groups (P > 0.05). Patients with neck pain had smaller thickness of the lower trapezius muscle on the painful side compared with healthy controls. Muscle Nerve 54: 439-443, 2016. © 2015 Wiley Periodicals, Inc.

We write to report a rare case of unilateral cancer-associated retinopathy previously undocumented in the literature. Cancer-associated retinopathy is an uncommon paraneoplastic syndrome. It is characterised by retinal antigen autoantibodies causing rod and cone dysfunction and abnormal electroretinography findings with consequent progressive visual loss.Our patient, known to have a primary cervical intraepithelial neoplasia, presented with unilateral blurred vision as well as a disturbance in colour and night vision. Electroretinography findings of reduced a and b waves in the right eye, together with a fundoscopic appearance of a mottled retinal pigment epithelium, attenuated blood vessels and optic disc pallor were consistent with unilateral cancer-associated retinopathy. Posterior subtenon injections of triamcinolone were administered to control active disease. With periocular steroid injections, at 4 years, our patient's visual acuity remained relatively stable and her condition persisted strictly unilaterally. Cancer-associated retinopathy may be the first presenting sign of an underlying malignancy or may indicate its recurrence. Moreover, in patients with a diagnosed gynaecological malignancy, visual symptoms could reflect cancer-associated retinopathy. In our patient visual symptoms came secondary to the diagnosis of cancer. © The Author(s) 2015.

Intrinsic Limitations to Unilateral Parathyroid Exploration

1999-01-01

Objective To evaluate a method of limited parathyroid exploration for primary hyperparathyroidism. Summary Background Data Although preoperative localization of parathyroid adenomas has become sensitive enough for clinical practice, it has not achieved success as the basis for limited parathyroid exploration, because multiglandular disease is routinely underdiagnosed. The rapid intraoperative parathyroid hormone assay is sensitive for multiglandular disease, because hormone levels will not fall within 10 minutes of adenoma removal if additional abnormal tissue is present. A combination technique in which the exploration is limited according to the localization studies and the success is confirmed with the parathyroid hormone assay has promise for producing a high rate of curative limited parathyroid explorations. Methods Forty-eight consecutive patients with primary hyperparathyroidism and indications for surgery underwent preoperative localization. After tests, 45 patients underwent unilateral parathyroid exploration and confirmation of the success of unilateral exploration during surgery using the rapid parathyroid hormone assay. The intraoperative management of these patients and their follow-up to 3 months was recorded. Results Thirty-two of the 48 patients (67%) had successful unilateral exploration as gauged by a marked drop in parathyroid hormone levels during the procedure and by 3-month clinical follow-up. Of the 16 patients who ultimately underwent bilateral exploration, 7 had parathyroid hormone levels that did not fall after adenoma removal. Of these seven, five were found to have a second adenoma and two had slow metabolism of hormone with no additional abnormal tissue found. In 5 of the 16 patients, bilateral exploration was performed for erroneous localization. Four additional patients underwent bilateral exploration for improved exposure or negative results on localization tests. Conclusions These results show that unilateral parathyroid exploration

Changes in regional cerebral blood flow (rCBF) induced by unilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) were investigated in 7 consecutive patients with Parkinson's disease, 4 men and 3 women (mean age 62.3 +/- 8.1 years), who underwent rCBF measurement by N-isopropyl-p-(iodine-123)-iodoamphetamine single photon emission computed tomography at rest before and after unilateral STN DBS preoperatively in the on-drug condition, and postoperatively in the on-drug and on-stimulation condition. Statistical parametric mapping was used to identify significant changes in rCBF from the preoperative to the postoperative conditions. rCBF was increased in the bilateral cingulate cortices and bilateral cerebellar hemispheres. rCBF was decreased in the bilateral medial frontal cortices and left superior temporal cortex. Unilateral STN DBS produced rCBF changes in the bilateral cingulate cortices, cerebellar hemispheres, and medial frontal cortices. These findings indicate that unilateral STN DBS affects rCBF in both hemispheres.

Objectives The shape of the flow-volume (F-V) curve is known to change to showing a prominent plateau as stenosis progresses in patients with tracheal stenosis. However, no study has evaluated changes in the F-V curve according to the degree of bronchial stenosis in patients with unilateral main bronchial stenosis. Methods We performed an analysis of F-V curves in 29 patients with unilateral bronchial stenosis with the aid of a graphic digitizer between January 2005 and December 2011. Results The primary diseases causing unilateral main bronchial stenosis were endobronchial tuberculosis (86%), followed by benign bronchial tumor (10%), and carcinoid (3%). All unilateral main bronchial stenoses were classified into one of five grades (I, ≤25%; II, 26%-50%; III, 51%-75%; IV, 76%-90%; V, >90% to near-complete obstruction without ipsilateral lung collapse). A monophasic F-V curve was observed in patients with grade I stenosis and biphasic curves were observed for grade II-IV stenosis. Both monophasic (81%) and biphasic shapes (18%) were observed in grade V stenosis. After standardization of the biphasic shape of the F-V curve, the breakpoints of the biphasic curve moved in the direction of high volume (x-axis) and low flow (y-axis) according to the progression of stenosis. Conclusion In unilateral bronchial stenosis, a biphasic F-V curve appeared when bronchial stenosis was >25% and disappeared when obstruction was near complete. In addition, the breakpoint moved in the direction of high volume and low flow with the progression of stenosis. PMID:26045916

As metoclopramide stimulates aldosterone secretion, we tested its usefulness in the assessment of lateralization of primary aldosteronism by adrenal vein sampling (AVS). Prospective within-patient study in consecutive patients undergoing AVS for primary aldosteronism subtyping. We compared the diagnostic accuracy of baseline and postmetoclopramide lateralization index and relative (to cortisol) aldosterone secretion indices (RASI) for each adrenal gland with aldosterone-producing adenoma (APA) determined by the four corners criteria as the reference diagnosis. We recruited 93 consecutive patients (mean age: 52 years; women 31%). Metoclopramide increased plasma aldosterone in the inferior vena cava and in both adrenal veins. The postmetoclopramide lateralization index was accurate in identifying APA, but did not increase diagnostic accuracy over baseline lateralization index, because the RASI increased similarly in both sides. Conversely, metoclopramide raised RASI to values more than 0.90 bilaterally in non-APA patients allowing accurate identification of factitious aldosterone suppression. In contrast, RASI was 0.90 or less in 48% contralateral to the tumor in APA patients. Regression analysis showed the APA patients with persistent suppression of RASI contralaterally showed a more florid primary aldosteronism phenotype. Metoclopramide does not enhance lateralization of aldosterone excess in APA, but consistently increased the value of RASI in non-APA cases, thus unmasking potentially misleading suppression of aldosterone. Postmetoclopramide RASI may therefore allow a more precise diagnosis when AVS can be achieved only unilaterally.

Percutaneous endoscopic contralateral interlaminar lumbar foraminotomy (PECILF) for lumbar degenerative spinal stenosis is an established procedure. Better preservation of contralateral facet joint compared with that of the approach side has been shown with uniportal bilateral decompression. The aim of this retrospective case series was to analyze the early clinical and radiologic outcomes of stand-alone contralateral foraminotomy and lateral recess decompression using PECILF. Twenty-six consecutive patients with unilateral lower limb radiculopathy underwent contralateral foraminotomy and lateral recess decompression using PECILF. Their clinical outcomes were evaluated with visual analog scale leg pain score, Oswestry Disability Index, and the MacNab criteria. Completeness of decompression was documented with a postoperative magnetic resonance imaging. Mean age for the study group was 62.9 ± 9.2 years and the male/female ratio was 4:9. A total of 30 levels were decompressed, with 18 patients (60%) undergoing decompression at L4-L5, 9 at L5-S1 (30%), 2 at L3-L4 (6.7%), and 1 at L2-L3 (3.3%). Mean estimated blood loss was 27 ± 15 mL per level. Mean operative duration was 48 ± 12 minutes/level. Visual analog scale leg score improved from 7.7 ± 1 to 1.8 ± 0.8 (P < 0.0001). Oswestry Disability Index improved from 64.4 ± 5.8 to 21 ± 4.5 (P < 0.0001). Mean follow-up of the study was 13.7 ± 2.7 months. According to the MacNab criteria, 10 patients (38.5%) had good results, 14 patients (53.8%) had excellent results, and 2 patients (7.7%) had fair results. One patient required revision surgery. Facet-preserving contralateral foraminotomy and lateral recess decompression with PECILF is effective for treatment of lateral recess and foraminal stenosis. Thorough decompression with acceptable early clinical outcomes and minimal perioperative morbidity can be obtained with the contralateral endoscopic approach. Copyright © 2017 Elsevier Inc.

In patients who experience unilateral chronic pain, abnormal sensory perception at the non-painful side has been reported. Contralateral sensory changes in these patients have been given little attention, possibly because they are regarded as clinically irrelevant. Still, bilateral sensory changes in these patients could become clinically relevant if they challenge the correct identification of their sensory dysfunction in terms of hyperalgesia and allodynia. Therefore, we have used the standardized quantitative sensory testing (QST) protocol of the German Research Network on Neuropathic Pain (DFNS) to investigate somatosensory function at the painful side and the corresponding non-painful side in unilateral neuropathic pain patients using gender- and age-matched healthy volunteers as a reference cohort. Sensory abnormalities were observed across all QST parameters at the painful side, but also, to a lesser extent, at the contralateral, non-painful side. Similar relative distributions regarding sensory loss/gain for non-nociceptive and nociceptive stimuli were found for both sides. Once a sensory abnormality for a QST parameter at the affected side was observed, the prevalence of an abnormality for the same parameter at the non-affected side was as high as 57% (for Pressure Pain Threshold). Our results show that bilateral sensory dysfunction in patients with unilateral neuropathic pain is more rule than exception. Therefore, this phenomenon should be taken into account for appropriate diagnostic evaluation in clinical practice. This is particularly true for mechanical stimuli where the 95% Confidence Interval for the prevalence of sensory abnormalities at the non-painful side ranges between 33% and 50%. PMID:22629414

To evaluate the changes in vision-related quality of life in patients with lacrimal passage obstructions undergoing silicone tube intubations. Prospective, consecutive, comparative, interventional case series. Forty-five patients with the chief complaint of epiphora diagnosed with complete and unilateral lacrimal passage obstructions were enrolled. Exclusion criteria included history of congenital nasolacrimal stenosis; lacrimal passage obstructions resulting from trauma, tumor, or chemotherapy; previous lacrimal passage surgery; and partial and functional nasolacrimal duct obstructions. Silicone tube intubation using a Nunchaku-style tube was performed under direct visualization with dacryoendoscope in all patients. Operations were considered as successful when the irrigating fluid could pass through the lacrimal passage and the disappearance of dye was observed in dye disappearance test and the patients' epiphora symptoms improved 3 months postoperatively. The 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) was self-administered in all patients preoperatively and 3 months postoperatively. Patients' preoperative and 3-months-postoperative NEI VFQ-25 scores were compared. Operations were successful in 40 patients (89%). Fully completed questionnaires were received from 32 patients (80%). Silicone tube intubation using a Nunchaku-style tube was associated with a significant improvement of the NEI VFQ-25 composite score (P = .0001), ocular pain score (P < .0001), and mental health score (P = .0003). Relief of epiphora by silicone tube intubation using a Nunchaku-style tube treatment significantly improved the vision-related quality of life in patients with lacrimal passage obstructions.

Five cases of unilateral occupation-related pseudogynecomastia are presented. All the patients in these cases worked in the same metal-pressing factory. One patient with grade 4 unilateral gynecomastia in the right breast presented to the authors' outpatient department asking persistently for surgery. He also reported that all his male colleagues working in the same business (a total of 5) had different degrees of unilateral gynecomastia. Their line of work involved holding a long round rod under the axilla and then pressing the distal end of it firmly against a spinning metal plate. The patient underwent a superior pedicle breast reduction, with 1,800 ml of tissue removed from his right breast. Unfortunately, the patient experienced partial nipple loss. However, he was satisfied with the final result, and good symmetry was achieved. All five patients who worked in the same metal-pressing factory presented with unilateral gynecomastia and were examined in our department. Their average age was 51.4 years. All the patients had normal hormonal and biochemical status, and the results of screening for toxins and heavy metal exposure were negative. All the patients were heavy smokers. At examination, none of the patients had nipple discharge or retraction, skin changes, galactorrhea, or lymphadenopathy. Examination showed one patient with grade 4, three patients had grade 2, and one patient with grade 1 unilateral gynecomastia. The authors believe that gynecomastia may be considered an occupational risk in analogous metal-pressing factories because all the workers in this factory presented with some degree of unilateral gynecomastia. However, they emphasize that this may simply be an observational phenomenon without a true cause and effect relationship.

Lumbosacral radiculopathy is a pathological process that refers to the dysfunction of one or more spinal nerve roots in the lumbosacral region of the spine. Some studies have shown that infrared thermography can estimate the severity of the clinical manifestation of unilateral lumbosacral radiculopathy. This study aimed to examine the correlation of the regional thermal deficit of the affected lower extremity with pain intensity, mobility of the lumbar spine, and functional status in patients with unilateral lumbosacral radiculopathy. This cross-sectional study was conducted at the Clinic for Physical Medicine and Rehabilitation of the Clinical Center Niš, Serbia. A total of 69 patients with unilateral lumbosacral radiculopathy of discogenic origin were recruited, with the following clinical parameters evaluated: (1) pain intensity by using a visual analogue scale, separately at rest and during active movement; (2) mobility of the lumbar spine by Schober test and the fingertip-to-floor test; and (3) functional status by the Oswestry Disability Index. Temperature differences between the symmetrical regions of the lower extremities were detected by infrared thermography. A quantitative analysis of thermograms determined the regions of interest with maximum thermal deficit. Correlation of maximum thermal deficit with each tested parameter was then determined. A significant and strong positive correlation was found between the regional thermal deficit and pain intensity at rest, as well as pain during active movements (rVAS - rest=0.887, rVAS - activity=0.890; P<0.001). The regional thermal deficit significantly and strongly correlated with the Oswestry Disability Index score and limited mobility of the lumbar spine (P<0.001). In patients with unilateral lumbosacral radiculopathy, the values of regional thermal deficit of the affected lower extremity are correlated with pain intensity, mobility of the lumbar spine, and functional status of the patient.

Objectives This study aimed to review general anaesthesia protocols for patients undergoing electroconvulsive therapy (ECT) at a tertiary care hospital in Oman, particularly with regards to clinical profile, potential drug interactions and patient outcomes. Methods This retrospective study took place at the Sultan Qaboos University Hospital (SQUH), Muscat, Oman. The electronic medical records of patients undergoing ECT at SQUH between January 2010 and December 2014 were reviewed for demographic characteristics and therapy details. Results A total of 504 modified ECT sessions were performed on 57 patients during the study period. All of the patients underwent a uniform general anaesthetic regimen consisting of propofol and succinylcholine; however, they received different doses between sessions, as determined by the treating anaesthesiologist. Variations in drug doses between sessions in the same patient could not be attributed to any particular factor. Self-limiting tachycardia and hypertension were periprocedural complications noted among all patients. One patient developed aspiration pneumonitis (1.8%). Conclusion All patients undergoing ECT received a general anaesthetic regimen including propofol and succinylcholine. However, the interplay of anaesthetic drugs with ECT efficacy could not be established due to a lack of comprehensive data, particularly with respect to seizure duration. In addition, the impact of concurrent antipsychotic therapy on anaesthetic dose and subsequent complications could not be determined. PMID:28417028

To compare the central corneal thicknesses (CCT), peripheral corneal thicknesses, and corneal volumes (CV) of the 2 eyes of patients with unilateral age-related macular degeneration (AMD). Twenty patients who were diagnosed with unilateral AMD were included in this prospective study for the purpose of making comparison between the diseased and healthy eyes. Optical coherence tomography and fundus fluorescein angiography imaging were applied to all patients in order to confirm and reveal the presence of unilateral AMD. Then, the measurements of CCT, peripheral corneal thickness measured 4 mm distant from the center of the cornea (4 mm CT), and CV of each eye of these patients were obtained through the rotating Scheimpflug corneal topographer. Wilcoxon signed-rank test did not demonstrate a statistically significant difference between the 2 eyes of patients with unilateral AMD when we compared the CCT and CV of diseased and healthy eyes (p>0.05). However, 4 mm CT of the diseased eyes of these patients were statistically significantly thicker than the healthy eyes (p<0.05). The significant difference in terms of 4 mm CT between the diseased and healthy eyes of patients with unilateral AMD may demonstrate the possible effect of peripheral corneal thickness on the development of AMD.

Gynecomastia is benign enlargement of male breast, drug-induced gynecomastia accounts for about 25%. We are reporting a case of spironolactone-induced unilateral gynecomastia. A 52-year-old male patient receiving multiple antihypertensives including hydrochlorothiazide presented with muscle weakness and easy fatigability. Investigations revealed hypokalemia; he was advised to stop hydrochlorothiazide and consume potassium-rich diet; since he did not respond to this, spironolactone was added. The patient improved symptomatically but developed painful swelling of the right breast after 12 months of treatment which was suspected to be spironolactone-induced gynecomastia. Within a month of stopping the drug, pain in the right breast subsided followed by decrease in size of swelling. Literature search indicates bilateral gynecomastia by spironolactone, but when clinician encounters unilateral presentation, they should consider the possibility of drug-induced etiology. Patients should be educated about this while prescribing, and eplerenone can be a safe alternative. PMID:29552536

To determine the clinical efficiency and long-term outcomes between unilateral and bilateral stent insertion in patients with malignant hilar biliary obstruction. From August 2012 to February 2016, 63 consecutive patients with malignant hilar biliary obstruction were treated with unilateral or bilateral stent insertion at our center. The bilateral stents were inserted using the side-by-side technique. The clinical efficiency and long-term outcomes were compared between the two groups. Unilateral and bilateral stent insertions were successfully performed in 31 of 33 and 27 of 30 patients, respectively (P = 0.912). No procedure-related complication occurred. Clinical success was achieved in 29 of 31 patients in the unilateral stent group and in 26 of 27 patients in the bilateral stent group (P = 0.637). During the follow-up, re-obstruction of stent occurred in five patients in the unilateral stent group and in three patients in the bilateral stent group (P = 0.58). The significant differences were not observed in the stent patency time (368 vs. 387 days, P = 0.685) and survival (200 vs. 198 days, P = 0.751) between two groups. Based on the univariate and multivariate analyses, the independent risk factors for decreasing the survival time included higher Eastern Cooperative Oncology Group performance status (P = 0.018), higher alanine aminotransferase level (P = 0.009), and absence of anticancer treatment after stent insertion (P = 0.002). Compared to bilateral stent insertion for malignant hilar biliary obstruction, unilateral stent insertion can provide comparable clinical efficiency and long-term outcomes.

To characterize the profile and speech characteristics of patients undergoing primary palatoplasty in a Brazilian university hospital, considering the time of intervention (early, before two years of age; late, after two years of age). Participants were 97 patients of both genders with cleft palate and/or cleft and lip palate, assigned to the Speech-language Pathology Department, who had been submitted to primary palatoplasty and presented no prior history of speech-language therapy. Patients were divided into two groups: early intervention group (EIG) - 43 patients undergoing primary palatoplasty before 2 years of age and late intervention group (LIG) - 54 patients undergoing primary palatoplasty after 2 years of age. All patients underwent speech-language pathology assessment. The following parameters were assessed: resonance classification, presence of nasal turbulence, presence of weak intraoral air pressure, presence of audible nasal air emission, speech understandability, and compensatory articulation disorder (CAD). At statistical significance level of 5% (p≤0.05), no significant difference was observed between the groups in the following parameters: resonance classification (p=0.067); level of hypernasality (p=0.113), presence of nasal turbulence (p=0.179); presence of weak intraoral air pressure (p=0.152); presence of nasal air emission (p=0.369), and speech understandability (p=0.113). The groups differed with respect to presence of compensatory articulation disorders (p=0.020), with the LIG presenting higher occurrence of altered phonemes. It was possible to assess the general profile and speech characteristics of the study participants. Patients submitted to early primary palatoplasty present better speech profile.

Case-control study. To investigate whether oxygen consumption and blood flow at rest and after exercise are lower in the affected arm of patients with repetitive strain injury (RSI) compared to controls, and lower in the healthy nonaffected forearm within patients with unilateral RSI. RSI is considered an upper extremity overuse injury. Despite the local presentation of complaints, RSI may be represented by systemic adaptations. Insight into the pathophysiology of RSI is important to better understand the development of RSI complaints and to develop effective treatment and prevention strategies. Twenty patients with unilateral RSI and 20 gender-matched control subjects participated in this study. Forearm muscle blood flow and oxygen consumption were measured using near-infrared spectroscopy at baseline and immediately after isometric handgrip exercises at 10%, 20%, and 40% of the individual maximal voluntary contraction. Unilateral RSI resulted in a lower oxygen consumption and blood flow in the affected forearm at baseline and lower oxygen consumption after incremental handgrip exercises compared to controls (P<.05). In addition, exercise-induced blood flow and oxygen consumption in the nonaffected forearm in patients with RSI were similarly reduced. Blood flow and oxygen consumption after exercise are similarly attenuated in the affected and nonaffected arms of patients with unilateral RSI. Our findings suggest that, despite the unilateral character in clinical symptoms, RSI demonstrates systemic adaptations in forearm blood flow and oxygen consumption at rest and after exercise.

[Primary hyperaldosteronism due to unilateral adrenal hyperplasia with surgical resolution].

PubMed

Rubio-Puchol, O; Garzón-Pastor, S; Salom-Vendrell, C; Hernández-Mijares, A

Unilateral adrenal hyperplasia is a rare cause of primary hyperaldosteronism (around a 3%) that has surgical treatment. A case of a patient with hypertension resistant to conventional therapy in treatment with 7 drugs who presented with primary hyperaldosteronism due to unilateral adrenal hyperplasia is presented. A left adrenalectomy was performed, and the patient had a good clinical response, with no need of any drug after 2 years of surgery. Unilateral adrenal hyperplasia is a different entity and it is not an asymmetric variant of the bilateral adrenal hyperplasia. In the study of patients with primary hyperaldosteronism and imaging tests with absence of adenoma is a diagnosis that must be considered before cataloguing patients with bilateral adrenal hyperplasia and start a medical treatment, because unilateral adrenal hyperplasia would have a surgical resolution.

Previous research has indicated that the medial temporal lobe (MTL), and more specifically the perirhinal cortex, plays a role in the feeling of familiarity for non-musical stimuli. Here, we examined contribution of the MTL to the feeling of familiarity for music by testing patients with unilateral MTL lesions. We used a gating paradigm: segments of familiar and unfamiliar musical excerpts were played with increasing durations (250, 500, 1000, 2000, 4000 ms and complete excerpts), and participants provided familiarity judgments for each segment. Based on the hypothesis that patients might need longer segments than healthy controls (HC) to identify excerpts as familiar, we examined the onset of the emergence of familiarity in HC, patients with a right MTL resection (RTR), and patients with a left MTL resection (LTR). In contrast to our hypothesis, we found that the feeling of familiarity was relatively spared in patients with a right or left MTL lesion, even for short excerpts. All participants were able to differentiate familiar from unfamiliar excerpts as early as 500 ms, although the difference between familiar and unfamiliar judgements was greater in HC than in patients. These findings suggest that a unilateral MTL lesion does not impair the emergence of the feeling of familiarity. We also assessed whether the dynamics of the musical excerpt (linked to the type and amount of information contained in the excerpts) modulated the onset of the feeling of familiarity in the three groups. The difference between familiar and unfamiliar judgements was greater for high than for low-dynamic excerpts for HC and RTR patients, but not for LTR patients. This indicates that the LTR group did not benefit in the same way from dynamics. Overall, our results imply that the recognition of previously well-learned musical excerpts does not depend on the integrity of either right or the left MTL structures. Patients with a unilateral MTL resection may compensate for the effects of

The aim of this study was to analyze the 10-year results of thoracoscopic unilateral extended thymectomy (TUET) performed in nontumoral myasthenia gravis according to the Myasthenia Gravis Foundation of America recommendations. Thoracoscopic unilateral extended thymectomy has the benefits of a minimally invasive approach. Previous data have shown promising midterm results but long-term results were lacking. Two hundred forty patients with nontumoral myasthenia gravis who underwent surgery between 1999 and 2009 were eligible for the study. The mean follow-up was of 67 months (range: 12-125), 134 patients completed follow-up assessments more than 60 months after TUET. There were 39 males (16.3%) and 201 females (83.7%), with an age range from 8 to 60 years. The mean preoperative disease duration was 21.5 months. All patients underwent preoperative steroid therapy. Anticholinesterase drugs were required for 123 patients (51.3%), and immunosuppressive drugs were required for 87 (36.3%) patients. The pathologic findings were as follows: normal thymus in 13 patients (5.5%), involuted thymus in 65 patients (27%), and hyperplastic thymus in 162 patients (67.5%). The average weight of the thymus was 110 ± 45 g. Ectopic thymic tissue was found in 147 patients (61.3%). There was no mortality, and morbidity consisted of 12 patients (5%). Complete stable remission was achieved in 61% of the patients, and the cumulative probability of achieving complete stable remission was 0.88 at 10 years. With zero mortality, low morbidity, and comparable long-term results to open surgery, TUET can be regarded as the best treatment option for patients undergoing surgery for myasthenia gravis.

Spinal hemianesthesia: Unilateral and posterior

PubMed Central

Imbelloni, Luiz Eduardo

2014-01-01

The injection of a non-isobaric local anesthetic should induce a unilateral spinal anesthesia in patients in a lateral decubitus position. The posterior spinal hemianesthesia only be obtained with hypobaric solutions injected in the jackknife position. The most important factors to be considered when performing a spinal hemianesthesia are: type and gauge of the needle, density of the local anesthetic relative to the CSF, position of the patient, speed of administration of the solution, time of stay in position, and dose/concentration/volume of the anesthetic solution. The distance between the spinal roots on the right-left sides and anterior-posterior is, approximately, 10-15 mm. This distance allows performing unilateral spinal anesthesia or posterior spinal anesthesia. The great advantage of obtaining spinal hemianesthesia is the reduction of cardiovascular changes. Likewise, both the dorsal and unilateral sensory block predominates in relation to the motor block. Because of the numerous advantages of producing spinal hemianesthesia, anesthesiologists should apply this technique more often. This review considers the factors which are relevant, plausible and proven to obtain spinal hemianesthesia. PMID:25886320

Objective: To describe the features of adult patients with benign, unilateral cerebral cortical encephalitis positive for the myelin oligodendrocyte glycoprotein (MOG) antibody. Methods: In this retrospective, cross-sectional study, after we encountered an index case of MOG antibody–positive unilateral cortical encephalitis with epileptic seizure, we tested for MOG antibody using our in-house, cell-based assay in a cohort of 24 consecutive adult patients with steroid-responsive encephalitis of unknown etiology seen at Tohoku University Hospital (2008–2014). We then analyzed the findings in MOG antibody–positive cases. Results: Three more patients, as well as the index case, were MOG antibody–positive, and all were adult men (median age 37 years, range 23–39 years). The main symptom was generalized epileptic seizure with or without abnormal behavior or consciousness disturbance. Two patients also developed unilateral benign optic neuritis (before or after seizure). In all patients, brain MRI demonstrated unilateral cerebral cortical fluid-attenuated inversion recovery hyperintense lesions, which were swollen and corresponded to hyperperfusion on SPECT. CSF studies showed moderate mononuclear pleocytosis with some polymorphonuclear cells and mildly elevated total protein levels, but myelin basic protein was not elevated. A screening of encephalitis-associated autoantibodies, including aquaporin-4, glutamate receptor, and voltage-gated potassium channel antibodies, was negative. All patients received antiepilepsy drugs and fully recovered after high-dose methylprednisolone, and the unilateral cortical MRI lesions subsequently disappeared. No patient experienced relapse. Conclusions: These MOG antibody–positive cases represent unique benign unilateral cortical encephalitis with epileptic seizure. The pathology may be autoimmune, although the findings differ from MOG antibody–associated demyelination and Rasmussen and other known immune

Management of coagulation in neurosurgical procedures is challenging. In this contest, it is imperative to avoid further intracranial bleeding. Perioperative bleeding can be associated with a number of factors, including anticoagulant drugs and coagulation status but is also linked to the characteristic and the site of the intracranial disorder. The aim of this review will be to focus primarily on the new evidence regarding the management of coagulation in patients undergoing craniotomy for neurosurgical procedures. Antihemostatic and anticoagulant drugs have shown to be associated with perioperative bleeding. On the other hand, an increased risk of venous thromboembolism and hypercoagulative state after elective and emergency neurosurgery, in particular after brain tumor surgery, has been described in several patients. To balance the risk between thrombosis and bleeding, it is important to be familiar with the perioperative changes in coagulation and with the recent management guidelines for anticoagulated patients undergoing neurosurgical procedures, in particular for those taking new direct anticoagulants. We have considered the current clinical trials and literature regarding both safety and efficacy of deep venous thrombosis prophylaxis in the neurosurgical population. These were mainly trials concerning both elective surgical and intensive care patients with a poor grade intracranial bleed or multiple traumas with an associated severe traumatic brain injury (TBI). Coagulation management remains a major issue in patients undergoing neurosurgical procedures. However, in this field of research, literature quality is poor and further studies are necessary to identify the best strategies to minimize risks in this group of patients.

Evidences suggest that different subgroups of idiopathic clubfoot exist with differences in severity and treatment outcomes. This study compares the severity and treatment outcomes of unilateral and bilateral clubfoot. We retrospectively studied 161 patients (bilateral 66, unilateral 95) with primary idiopathic clubfeet to evaluate the differences in severity and treatment. The parameters analyzed were precasting Pirani score, number of casts required, pretenotomy Pirani score, pretenotomy dorsiflexion, rate of tenotomy, and post-tenotomy dorsiflexion achieved. A Pirani score of at least 5 was classified as very severe and 4.5 or less was classified as less severe. There were 49=(74.24%) male and 17 (25.75%) female patients in the bilateral group and 76 (80%) male and 19 (20%) female patients in the unilateral group. Out of 95 unilateral patients, 34 were left sided (35.8%). Comparing severity, the mean precasting Pirani score in bilateral patients (5.4 ± 0.6) was statistically more than the unilateral patients (4.9 ± 0.7). The number of casts required was significantly more in bilateral feet compared to unilateral (bilateral 5.3 ± 1.7, unilateral 4.7 ± 1.7; p < 0.011). Achilles tenotomy was required in all feet. Post Ponseti treatment, the foot deformity correction achieved (pretenotomy Pirani score, pretenotomy, and post-tenotomy dorsiflexion) was statistically similar in both unilateral and bilateral feet. Idiopathic bilateral clubfoot was more severe than unilateral foot at initial presentation and required more number of corrective casts. Post Ponseti treatment, the deformity correction in bilateral foot was similar to unilateral foot.

Most types of craniosynostosis cause predictable changes in cranial shape. However, the phenotype of combined metopic and unilateral coronal synostoses is anomalous. The purpose of this observational study was to better clarify the clinical and radiographic features of this rare entity. A retrospective review of a craniofacial database was performed. Patients with combined metopic and unilateral coronal synostoses were included in this study. Data collected included demographic information, physical and radiographic findings, genetic evaluation, treatment, and operative outcomes. Of 687 patients treated between 1989 and 2010, only 3 patients had combined metopic and unilateral coronal synostoses. All patients were diagnosed through computed tomography on the first day of life. Phenotypic features included the following: (1) narrowed forehead with a prominent midline ridge, (2) severe bilateral brow retrusion with an acute indentation on the side of the patient coronal suture, (3) facial and nasal angulation similar to isolated unilateral coronal synostosis, and (4) anterior displacement of the ear on the fused side. In addition, the cranial vertex was deviated toward the side of the open coronal suture. Two patients had a head circumference below the 25th percentile; 2 of the 3 had a TWIST gene mutation consistent with Saethre-Chotzen syndrome. One patient was managed through fronto-orbital advancement and required a revision. The other 2 patients had early endoscopic release, followed by postoperative helmet therapy; one improved but still required open cranial remodeling. The other has near-normal phenotype, and no further surgery is planned. Combined metopic and unilateral coronal synostoses present a rare and unusual phenotype. Although early intervention improves the deformity, revisional procedures are usually required.

Previous clinical trials have demonstrated benefit with the addition of continuous infusion (CI) ketorolac to a multimodal pain regimen in surgical patients. Data following major orthopedic surgery are minimal and conflicting. To evaluate CI ketorolac use following unilateral total knee arthroplasty (TKA) through assessment of patient-reported pain scores, opioid consumption, and safety outcomes. This was a retrospective, open-label cohort study that included patients undergoing unilateral TKA at a single-center teaching hospital. Participants were categorized into 2 study groups based on postoperative management: CI ketorolac or opioid protocol (OP). The first group received a ketorolac 30-mg bolus followed by CI 3.6 mg/h plus as-needed (PRN) opioids. The OP group received PRN narcotics in a tiered protocol. The primary end point was comparison of median pain scores. Secondary end points included opioid consumption (morphine equivalent units [MEUs]) in the first 48 hours postoperatively, length of stay, and adverse effects. Of 447 patients screened, 191 were analyzed (CI ketorolac, n = 116; OP, n = 75). Median pain scores were significantly lower in the CI ketorolac group at 48 hours postoperatively (3 [2-4] vs 3.5 [2.5-5], P = 0.033). Cumulative MEUs at 48 hours were significantly lower in the CI ketorolac group (33.9 ± 38.5 mg vs 301.6 ± 36.6 mg, P < 0.001). Patients in the CI ketorolac group experienced less respiratory depression (5.2% vs 25.3%, P < 0.001) and less naloxone administration (0% vs 8%, P = 0.002) compared with the OP group. Other adverse effects were similar among groups. Postoperative CI ketorolac improved pain control while reducing opioid consumption and adverse effects.

Nasoalveolar molding was developed to improve dentoalveolar, septal, and lower lateral cartilage position before cleft lip repair. Previous studies have documented the long-term maintenance of columella length and nasal dome form and projection. The purpose of the present study was to determine the effect of presurgical nasoalveolar molding on long-term unilateral complete cleft nasal symmetry. A retrospective review of 25 consecutively presenting nonsyndromic complete unilateral cleft lip-cleft palate patients was conducted. Fifteen patients were treated with presurgical nasoalveolar molding for 3 months before surgical correction, and 10 patients were treated by surgical correction alone. The average age at the time of follow-up was 9 years. Four nasal anthropometric distances and two angular relationships were measured to assess nasal symmetry. All six measurements demonstrated a greater degree of nasal symmetry in nasoalveolar molding patients compared with the patients treated with surgery alone. Five symmetry measurements were significantly more symmetric in the nasoalveolar molding patients and one measurement demonstrated a nonsignificant but greater degree of symmetry compared with the patients treated with surgery alone. The data demonstrate that the lower lateral and septal cartilages are more symmetric in the nasoalveolar molding patients compared with the surgery-alone patients. Furthermore, the improved symmetry observed in nasoalveolar molding-treated noses during the time of the primary surgery is maintained at 9 years of age.

To evaluate the effectiveness of 0.125% bupivacaine compared to 0.25% bupivacaine for ultrasound-guided transversus abdominis plane (TAP) block in patients undergoing open inguinal hernia repair. Randomized, double-blind study. Educational and research hospital. Forty adult patients of American Society of Anesthesiologists physical status I-III undergoing elective primary unilateral open inguinal hernia repair under spinal anesthesia. Patients in group I received 20 mL of 0.25% bupivacaine, whereas patients in group II received 20 mL of 0.125% bupivacaine for TAP block at the end of the surgery. Pain intensity was assessed at rest and during coughing using 10-cm visual analog scale score at 5, 15, 30, and 45 minutes and 1, 2, 4, 6, 12, and 24 hours after TAP block. Morphine consumption and time to first morphine requirement were recorded. Visual analog scale scores at rest and during coughing were not significantly different between groups at all time points measured. Twenty-four hours of morphine consumption (7.72±7.33 mg in group I and 6.06±5.20 mg in group II; P=.437) and time to first morphine requirement (182.35±125.16 minutes in group I and 143.21±87.28 minutes in group II; P=.332) were not different between groups. 0.125% Bupivacaine provides similar analgesic effect compared to 0.25% bupivacaine for ultrasound-guided TAP block in patients undergoing open inguinal hernia repair.

Antithrombotic agents are used increasingly in Asia. The management of patients on antithrombotics undergoing elective or emergency endoscopy has become an increasing clinical challenge for gastroenterologists. Current practice guidelines have been developed by societies from western countries. On the other hand, these guidelines cannot meet the specific needs of the Asian Pacific region, raising the need for separate guidelines in Asia. This review compares the recommendations of previous guidelines with the most recently published Asian guidelines regarding the management of patients on antithrombotic agents undergoing elective and emergency endoscopy.

The benefits of bone-anchored hearing devices (BAHD) in children with unilateral aural atresia are controversial. We sought to determine whether there is parental decisional conflict surrounding elective placement of BAHD for this indication. Caregivers of pediatric patients with unilateral aural atresia and normal contralateral ear undergoing percutaneous BAHD consultation were enrolled. All consultations were carried out by one pediatric otolaryngologist in a consistent manner. After consultation, the participants completed a demographics form and the Decisional Conflict Scale (DCS) questionnaire. Twenty-three caregivers of 15 male (65.2%) and 8 female (34.8%) children (mean age 5.65 years) participated. The overall median DCS score was 15.63 (standard error = 4.21). Significant decisional conflict (DCS score ≥ 25) was found in 10 participants (43.5%). The median DCS score in the group choosing surgery was 5.47, and it was 23.44 in those who did not choose surgery (Mann-Whitney U = 39, Z = -1.391, P = .164). The median DCS score for mothers and fathers was 25 and 3.91, respectively. Many parents experienced significant decisional conflict when considering percutaneous BAHD surgery in children with unilateral aural atresia in our study population. Future research should explore the impact of decisional conflict on health outcomes. © The Author(s) 2015.

Symptomatic leg length inequality accounts for 8.7% of total hip replacement related claims made against the UK National Health Service Litigation authority. It has not been established whether symptomatic leg length inequality patients following total hip replacement have abnormal hip kinetics during gait. Hip kinetics in 15 unilateral total hip replacement patients with symptomatic leg length inequality during gait was determined through multibody dynamics and compared to 15 native hip healthy controls and 15 'successful' asymptomatic unilateral total hip replacement patients. More significant differences from normal were found in symptomatic leg length inequality patients than in asymptomatic total hip replacement patients. The leg length inequality patients had altered functions defined by lower gait velocity, reduced stride length, reduced ground reaction force, decreased hip range of motion, reduced hip moment and less dynamic hip force with a 24% lower heel-strike peak, 66% higher mid-stance trough and 37% lower toe-off peak. Greater asymmetry in hip contact force was also observed in leg length inequality patients. These gait adaptions may affect the function of the implant and other healthy joints in symptomatic leg length inequality patients. This study provides important information for the musculoskeletal function and rehabilitation of symptomatic leg length inequality patients. Copyright © 2015. Published by Elsevier Ltd.

Objective: Case-control study analysis of the speech discrimination of unilateral microtia and external auditory canal atresia patients with normal hearing subjects in quiet and noisy environment. To understand the speech recognition results of patients with unilateral external auditory canal atresia and provide scientific basis for clinical early intervention. Method: Twenty patients with unilateral congenital microtia malformation combined external auditory canal atresia, 20 age matched normal subjects as control group. All subjects used Mandarin speech audiometry material, to test the speech discrimination scores (SDS) in quiet and noisy environment in sound field. Result: There's no significant difference of speech discrimination scores under the condition of quiet between two groups. There's a statistically significant difference when the speech signal in the affected side and noise in the nomalside (single syllable, double syllable, statements; S/N=0 and S/N=-10) ( P <0.05). There's no significant difference of speech discrimination scores when the speech signal in the nomalside and noise in the affected side. There's a statistically significant difference in condition of the signal and noise in the same side when used one-syllable word recognition (S/N=0 and S/N=-5) ( P <0.05), while double syllable word and statement has no statistically significant difference ( P >0.05). Conclusion: The speech discrimination scores of unilateral congenital microtia malformation patients with external auditory canal atresia under the condition of noise is lower than the normal subjects.

Genital elephantiasis is caused by a variety of infective and non infective causes leading to blockage of lymphatic. We are presenting a rare case of recurrent unilateral vulval elephantiasis which has recurred after initial reconstructive surgery. A 38 year old female presented with vulval swelling and on examination there was gross unilateral vulval enlargement. FNAC (Fine needle aspiration cytology) and biopsy were contributory for diagnosis. Patient was started with antibiotics and daily dressing was done till the infection was subsided and the patient was planned for reconstructive surgery. PMID:24971141

Medialization thyroplasty was effective in improving swallowing function as well as vocal function in most cases with unilateral vocal fold paralysis. The impact of medialization thryoplasty was insufficient for the case with severe atrophy and that in which the vocal fold was fixed in the lateral position. To evaluate the impacts and limitations of medialization thyroplasty on swallowing function of the patients with unilateral vocal fold paralysis. Eight cases (mean age 68.5 years) with unilateral vocal fold paralysis chiefly complaining of swallowing disturbance were studied. All patients underwent thyroplasty type I. The causes of the paralysis were lung cancer in four cases, esophageal cancer in one case, aortic aneurysm in one case, subarachnoid hemorrhage in one case, and unknown in one case. Subjective swallowing function score, maximum phonation time (MPT), mean flow rate (MFR), amplitude perturbation quotient (APQ), and pitch perturbation quotient (PPQ) were examined pre- and postoperatively. The swallowing score improved in all except two cases. However, bilateral thryoplasty was necessary for the case with severe vocal fold atrophy and arytenoid adduction was needed for the case in which the vocal fold was fixed in the lateral position. The swallowing score, MPT, and MFR showed significant improvement after surgery.

To investigate the feasibility of contralateral lower neck sparing intensity modulation radiated therapy (IMRT) for nasopharyngeal carcinoma patients (NPC) with unilateral cervical lymph node metastasis. Retrospective review of 546 patients with unilateral cervical lymph node metastasis treated between November 2009 and February 2012 at one institution. All patients were staged using magnetic resonance imaging and received radical IMRT. Patients were classified into two groups: the inferior border of the negative neck irradiation field only covered Levels III to Va in Group 1; the inferior border covered entire neck down to Levels IV to Vb in Group 2. Median follow-up was 49.9months (range, 1.3-69.2months). Four-year overall survival (OS:89.3% vs. 88.9%, P=0.91), disease-free survival (DFS:81.7% vs. 81.0%, P=0.91), distant metastasis-free survival (DMFS:88.2% vs. 87.9%, P=0.95), local relapse-free survival (LRFS:96.7% vs. 94.7%, P=0.70) and nodal relapse-free survival (NRFS: 96.1% vs. 95.9%, P=0.94) were not significantly different between Group 1 and Group 2. Twenty-two patients developed cervical lymph node relapse; of whom 20/22 (91.0%) developed unilateral relapse within pretreatment positive neck. Only one patient developed out-of-field relapse, though this patient also relapsed within the neck irradiation field (Level II). No clinicopathological feature tested had significant prognostic value for NRFS in multivariate analysis. In the IMRT and MRI era, contralateral lower neck sparing IMRT seems to be feasible for NPC patients with unilateral cervical lymph node metastasis. Copyright © 2017. Published by Elsevier Ltd.

Injection laryngoplasty (glottis augmentation) is the preferred method in surgical management of unilateral vocal fold paralysis (UVFP). Traditionally, these procedures are performed in the operating room. Nowadays, however, these procedures have moved into the office. To evaluate the voice quality after transoral injection laryngoplasty under local anaesthesia in patients with unilateral vocal fold paralysis. Fourteen subjects (5 women and 9 men) with unilateral vocal fold paresis (9 with right vocal fold paresis and 5 with left vocal fold paresis) were included in the study. The mean age of the group was 57.8 ±19.0 years (32-83 years). All of the injection laryngoplasties were performed transorally, under local anaesthesia. The injection material was calcium hydroxylapatite. Before and 1, 3 and 6 months after the procedure the following variables were evaluated: voice perception, videostroboscopy, acoustic analysis, aerodynamic evaluation, and the subjective rating of the voice quality by the patient. After injection laryngoplasty, complete glottal closure was achieved or there was a significant improvement in the glottal closure of each subject. We noted great improvement in the post-injection objective and subjective voice outcomes and patients reported improvement in the voice-related quality of life. The transoral approach for injection laryngoplasty under local anaesthesia is an effective and safe way to treat incomplete glottal closure in patients with UVFP. The transoral approach is an efficient alternative to other surgical techniques used for vocal fold injection.

Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant. We evaluated 25-hydroxyvitamin D serum levels in a representative sample of patients undergoing kidney transplant. We sought to determine the prevalence of hypovitaminosis D, compare these patients with a control group, and identify factors associated with hypovitaminosis D (e.g., sunlight exposure and dietary habits). Hypovitaminosis D was found in 79% of patients undergoing kidney transplant, and the major associated factor was low sunlight exposure. These patients had higher creatinine and intact parathyroid hormone serum levels, with 25-hydroxyvitamin D being inversely correlated with intact parathyroid hormone serum levels. Compared with the control group, patients undergoing kidney transplant presented a higher prevalence of 25-hydroxyvitamin D deficiency and lower serum calcium, phosphate and albumin but higher creatinine and intact parathyroid hormone levels. Our results confirmed the high prevalence of hypovitaminosis D in patients undergoing kidney transplant. Therapeutic strategies such as moderate sunlight exposure and vitamin D supplementation should be seriously considered for this population.

As bariatric surgery rates continue to climb, anaemia will become an increasing concern. We assessed the prevalence of anaemia and length of hospital stay in patients undergoing bariatric surgery. Prospective data (anaemia [haemoglobin <12 g/dL], haematinics and length of hospital stay) was analysed on 400 hundred patients undergoing elective laparoscopic bariatric surgery. Results from a prospective database of 1530 patients undergoing elective general surgery were used as a baseline. Fifty-seven patients (14%) were anaemic pre-operatively, of which 98% were females. Median MCV (fL) and overall median ferritin (μg/L) was lower in anaemic patients (83 vs. 86, p=0.001) and (28 vs. 61, p<0.0001) respectively. In the elective general surgery patients, prevalence of anaemia was similar (14% vs. 16%) but absolute iron deficiency was more common in those undergoing bariatric surgery; microcytosis p<0.0001, ferritin <30 p<0.0001. Mean length of stay (days) was increased in the anaemic compared to in the non-anaemic group (2.7 vs. 1.9) and patients who were anaemic immediately post-operatively, also had an increased length of stay (2.7 vs. 1.9), p<0.05. Absolute iron deficiency was more common in patients undergoing bariatric surgery. In bariatric patients with anaemia there was an overall increased length of hospital stay.

In humans, the control of voluntary movement, in which the corticobasal ganglia (BG) circuitry participates, is mainly lateralized. However, several studies have suggested that both the contralateral and ipsilateral BG systems are implicated during unilateral movement. Bilateral improvement of motor signs in patients with Parkinson's disease (PD) has been reported with unilateral lesion or high-frequency stimulation (HFS) of the internal part of the globus pallidus or the subthalamic nucleus (STN-HFS). To decipher the mechanisms of production of ipsilateral movements induced by the modulation of unilateral BG circuitry activity, we recorded left STN neuronal activity during right STN-HFS in PD patients operated for bilateral deep brain stimulation. Left STN single cells were recorded in the operating room during right STN-HFS while patients experienced, or did not experience, right stimulation-induced dyskinesias. Most of the left-side STN neurons (64%) associated with the presence of right dyskinesias were inhibited, with a significant decrease in burst and intraburst frequencies. In contrast, left STN neurons not associated with right dyskinesias were mainly activated (48%), with a predominant increase 4-5 ms after the stimulation pulse and a decrease in oscillatory activity. This suggests that unilateral neuronal STN modulation is associated with changes in the activity of the contralateral STN. The fact that one side of the BG system can influence the functioning of the other could explain the occurrence of bilateral dyskinesias and motor improvement observed in PD patients during unilateral STN-HFS, as a result of a bilateral disruption of the pathological activity in the corticosubcortical circuitry.

Evaluation of the effect of infant orthopedics on maxillary arch dimensions in the deciduous dentition in patients with unilateral cleft lip and palate. Prospective two-arm randomized controlled clinical trial with three participating cleft palate centers. Cleft palate centers of the Radboud University Nijmegen Medical Center, Academic Center of Dentistry Amsterdam, and University Medical Center Rotterdam, the Netherlands. Children with complete unilateral cleft lip and palate (n = 54) were included. Patients were randomly divided into two groups. Half of the patients (IO+) had a presurgical orthopedic plate until surgical closure of the soft palate at the age of 52 weeks; the other half (IO-) did not undergo presurgical orthopedics. Maxillary arch dimensions were assessed on dental casts at 4 and 6 years of age with measurements for arch width, arch depth, arch length, arch form, and the vertical position of the lesser segment. Contact and collapse were assessed also. There were no clinically significant differences found between IO+ and IO- for any of the variables. Infant orthopedics had no observable effect on the maxillary arch dimensions or on the contact and collapse scores in the deciduous dentition at the ages of 4 and 6 years. Considering the Dutchcleft results to date, there is no need to perform infant orthopedics for unilateral cleft lip and palate patients.

The phenomenon of occult carcinoma maybe observed in patients with clinically unilateral papillary thyroid microcarcinoma (PTMC). Although many studies have reported that the BRAFT1799A mutation is associated with aggressive PTMC, the relationship between BRAFT1799A mutation and occult carcinoma is unclear. The aim of this study was to investigate the risk factors, including BRAFT1799A mutation, for occult contralateral carcinoma in clinically unilateral PTMC accompanied by benign nodules in the contralateral lobe. From January 2011 to December 2013,we prospectively enrolled 89 consecutive PTMC patients with clinically unilateral carcinoma accompanied by benign nodules in the contralateral lobe who received a total thyroidectomy and cervical lymph node dissection. BRAFT1799A mutation was tested by pyrosequencing on postoperative paraffin specimens. The frequency and predictive factors for occult contralateral carcinoma were analyzed with respect to the following variables: age, gender, family history, tumor size, presence of Hashimoto thyroiditis, extrathyroidal extension, central lymph node metastasis, multifocality of primary tumor, or BRAFT1799A mutation. A total of 36 patients (40.4%) had occult PTMC in the contralateral lobe. The median diameter of the occult tumors was 0.33±0.21 cm. The BRAFT1799A mutation was found in 38 cases (42.7%). According to the univariate analysis, there were no significant differences between the presence of occult contralateral carcinoma and age, gender, family history, tumor size, presence of Hashimoto thyroiditis, extrathyroidal extension, central lymph node metastasis, multifocality of primary tumor, or BRAFT1799A mutation. Using current methods, it is difficult to preoperatively identify patients with PTMC, and further research is needed to determine predictive factors for the presence of occult contralateral carcinoma in patients with unilateral PTMC.

Clock-drawing test and unilateral spatial neglect.

We investigated the ability of 25 patients with left unilateral spatial neglect to make a clock face by putting numbers inside a printed circle. Impairment seen in this clock-drawing test did not parallel neglect severity as judged by results of the line-cancellation and line-bisection tests, as well as the copying of a daisy. The score for clock drawing correlated highly with the verbal WAIS score. Most neglect patients with a verbal IQ of 87 or more could draw a clock face fairly well and used planning in placing the numbers 12, 3, 6, and 9 before the others. In clock drawing, verbal intelligence may compensate for left unilateral spatial neglect. We therefore recommend use of the line-cancellation and line-bisection tests, as well as the copying test, but do not recommend use of the clock-drawing test in the diagnosis of left unilateral spatial neglect.

To study the clinical profile and presentation of children with unilateral cataract. In this hospital-based, observational, cross-sectional study, patients 15 years of age or younger who presented with unilateral cataract were recruited. Cases of cataract secondary to causes such as trauma or uveitis were excluded. Age at detection and presentation, distance from the treatment center, presenting complaints, cataract morphology, and biometry were noted for each case. A total of 76 patients were recruited. Most patients presented with complaints of leukocoria. Persistent fetal vasculature accounted for 27.6% of cases and was the most common identifiable cause of cataract in this study. Subsequently, patients were divided into two groups: no persistent fetal vasculature (control) and persistent fetal vasculature. A male predominance was noted in both groups. The mean age at detection was 27.58 ± 37.02 and 6.17 ± 8.42 months and the mean age at presentation was 55.613 ± 45.21 and 14.83 ± 17.75 months in the control and persistent fetal vasculature groups, respectively. In the persistent fetal vasculature group, a significant difference was noted in the axial length, keratometry, and corneal diameter between the affected and normal eyes (P = .027, .00176, and .0114, respectively). In the control group, this difference was observed only in keratometry readings (P = .0464). The mean distance traveled by patients to reach the treatment center was 211 km. Persistent fetal vasculature is an important and less identified cause of unilateral cataract. A significant delay is noted in the detection and presentation of unilateral cataract.

The unilateral cleft lip is a complex deformity. Surgical correction has evolved from a straight repair through triangular and quadrilateral repairs to the Rotation Advancement Technique of Millard. The latter is the technique followed at our centre for all unilateral cleft lip patients. We operate on these at five to six months of age, do not use pre-surgical orthodontics, and follow a protocol to produce a notch-free vermillion. This is easy to follow even for trainees. We also perform closed alar dissection and extensive primary septoplasty in all these patients. This has improved the overall result and has no long-term deleterious effect on the growth of the nose or of the maxilla. Other refinements have been used for prevention of a high-riding nostril, and correction of the vestibular web.

This study was aimed to evaluate the efficacy of preemptive analgesia (PA) by using celecoxib combined with low-dose tramadol/acetaminophen (tramadol/APAP) in treating post-operative pain of patients undergoing unilateral total knee arthroplasty (TKA). A total of 132 patients scheduled for TKA were included in this study. Three-day pre-operative medication was administrated in PA group with subsequent effective intra- and post-operative multimodal analgesia, while control patients received multimodal analgesia without PA. Visual analog scale (VAS) was utilized to assess the pain intensity at rest and during movement. VAS scores of participants were recorded 3 days before surgery, 1 day, 3 days, 1 week, 3 weeks, 6 weeks, 3 months, 6 months, and 12 months postoperatively. Moreover, the length of hospital stay, expense of hospitalization, C-reactive protein (CRP) values during hospitalization, and complications during medication were also recorded. PA showed superiority over control at 3 weeks (P = 0.013) and 6 weeks (P = 0.046) in resting pain, and 1 week (P = 0.015), 3 weeks (P = 0.003), 6 weeks (P = 0.003) and 3 months (P = 0.012) postoperatively in movement pain. There was no statistically significant difference in the length of hospital stay, total expense, CRP values, as well as complications. Based on satisfactory intra- and post-operative analgesia, PA by 3-day administration of celecoxib and low-dose tramadol/APAP might be an effective and safe therapy regarding patients undergoing TKA in terms of alleviating post-operative pain.

Postrenal acute kidney injury in a patient with unilateral ureteral obstruction caused by urolithiasis: A case report.

In patients with bilateral ureteral obstruction, the serum creatinine levels are often elevated, sometimes causing postrenal acute kidney injury (AKI). In contrast, those with unilateral ureteral obstruction present normal serum creatinine levels, as long as their contralateral kidneys are preserved intact. However, the unilateral obstruction of the ureter could affect the renal function, as it humorally influences the renal hemodynamics. A 66-year-old man with a past medical history of hypertension and diabetes mellitus came to our outpatient clinic because of right abdominal dullness. Unilateral ureteral obstruction caused by a radio-opaque calculus in the right upper ureter and a secondary renal dysfunction. As oral hydration and the use of calcium antagonists failed to allow the spontaneous stone passage, extracorporeal shock wave lithotripsy (ESWL) was performed. Immediately after the passage of the stone, the number of red blood cells in the urine was dramatically decreased and the serum creatinine level almost returned to the normal range with the significant increase in glomerular filtration rate. Unilateral ureteral obstruction by the calculus, which caused reflex vascular constriction and ureteral spasm in the contralateral kidney, was thought to be responsible for the deteriorating renal function.

OBJECTIVES: Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant. METHODS: We evaluated 25-hydroxyvitamin D serum levels in a representative sample of patients undergoing kidney transplant. We sought to determine the prevalence of hypovitaminosis D, compare these patients with a control group, and identify factors associated with hypovitaminosis D (e.g., sunlight exposure and dietary habits). RESULTS: Hypovitaminosis D was found in 79% of patients undergoing kidney transplant, and the major associated factor was low sunlight exposure. These patients had higher creatinine and intact parathyroid hormone serum levels, with 25-hydroxyvitamin D being inversely correlated with intact parathyroid hormone serum levels. Compared with the control group, patients undergoing kidney transplant presented a higher prevalence of 25-hydroxyvitamin D deficiency and lower serum calcium, phosphate and albumin but higher creatinine and intact parathyroid hormone levels. CONCLUSIONS: Our results confirmed the high prevalence of hypovitaminosis D in patients undergoing kidney transplant. Therapeutic strategies such as moderate sunlight exposure and vitamin D supplementation should be seriously considered for this population. PMID:28793001

Our aim in this study was to assess the impact of the turnover of residents in July on patients undergoing pituitary surgery. This work was a retrospective cohort study of cases from the National Inpatient Sample (NIS). Patients who underwent pituitary surgery from 2005 to 2012 were selected in the NIS. Patients undergoing surgery in July and in non-July months were compared to determine differences in demographics, comorbidities, and complications. Of the 12,939 patients, 1098 (8.5%) underwent pituitary surgery in July. Patients receiving surgery in July had similar demographics and Agency for Healthcare Research and Quality comorbidity values compared with patients receiving surgery in other months. There were no significant differences in mortality, cerebral edema, cerebrospinal fluid leakage, iatrogenic pituitary complications, iatrogenic cerebrovascular accidents, urinary tract infections, pulmonary edema, pulmonary complications, or acute cardiac complications. There were no differences in the rate of postoperative fistulas, hematomas, perforations, or infections. The use of meningeal suturing, pedicled or free-flap reconstruction, and skin reconstruction was more frequent in July. Finally, hospitalization costs in July were similar to costs in other months. The turnover of new residents in July showed no change in complication rates for patients undergoing pituitary surgery. Patient care in July is similar to care during other months, demonstrating that hospitals are adequately supervising surgical residents during this transition. © 2018 ARS-AAOA, LLC.

Dopaminergic stimulation in unilateral neglect

Geminiani, G.; Bottini, G.; Sterzi, R.

1998-01-01

OBJECTIVE—To explore the hypothesis that dopaminergic circuits play a part in the premotor components of the unilateral neglect syndrome, the effects of acute dopaminergic stimulation in patients with neglect were studied.
METHODS—Two tasks were evaluated before and after subcutaneous administration of apomorphine and placebo: a circle crossing test and a test of target exploration (a modified version of the bell test), performed both in perceptual (counting) and in perceptual-motor (pointing) conditions.
SUBJECTS—Four patients with left neglect.
RESULTS—After dopaminergic stimulation, a significant improvement was found compared with placebo administration and baseline evaluation, in the performance of the two tests. Three of the patients had a more marked improvement in the perceptual-motor condition (pointing) of the task than the perceptual condition (counting).
CONCLUSIONS—The findings suggest that dopaminergic neuronal networks may mediate, in different ways, both perceptive and premotor components of the unilateral neglect syndrome.

Unilateral condylar hyperplasia (UCH) is a disorder of unknown etiology mainly seen in growing patients, which results in facial asymmetry. High condylectomy alone or in association with orthognathic surgery can improve the occlusion and the facial aesthetics. Between 2005 and 2012, a total of 5 patients underwent high condylectomy for UCH using a piezoelectric cutting device. All patients were treated postoperatively with functional rehabilitation. The long-term follow-up showed that all patients had a satisfactory temporomandibular joint articular function associated with stable occlusion without any recurrence of further condylar growth. High condylectomy in the surgical treatment of unilateral UCH seems to be the procedure of choice in growing patients. The use of a piezoelectric cutting device allows a safe and less invasive high condylectomy.

Introduction Injection laryngoplasty (glottis augmentation) is the preferred method in surgical management of unilateral vocal fold paralysis (UVFP). Traditionally, these procedures are performed in the operating room. Nowadays, however, these procedures have moved into the office. Aim To evaluate the voice quality after transoral injection laryngoplasty under local anaesthesia in patients with unilateral vocal fold paralysis. Material and methods Fourteen subjects (5 women and 9 men) with unilateral vocal fold paresis (9 with right vocal fold paresis and 5 with left vocal fold paresis) were included in the study. The mean age of the group was 57.8 ±19.0 years (32–83 years). All of the injection laryngoplasties were performed transorally, under local anaesthesia. The injection material was calcium hydroxylapatite. Before and 1, 3 and 6 months after the procedure the following variables were evaluated: voice perception, videostroboscopy, acoustic analysis, aerodynamic evaluation, and the subjective rating of the voice quality by the patient. Results After injection laryngoplasty, complete glottal closure was achieved or there was a significant improvement in the glottal closure of each subject. We noted great improvement in the post-injection objective and subjective voice outcomes and patients reported improvement in the voice-related quality of life. Conclusions The transoral approach for injection laryngoplasty under local anaesthesia is an effective and safe way to treat incomplete glottal closure in patients with UVFP. The transoral approach is an efficient alternative to other surgical techniques used for vocal fold injection. PMID:29062449

Persistent dizziness and balance problems have been reported in some patients with unilateral vestibular pathology. The purpose of this case series was to address the examination and treatment of musculoskeletal dysfunction in patients with unilateral vestibular hypofunction. The musculoskeletal system was evaluated with the Global Physiotherapy Examination, dynamic balance was measured during walking with triaxial accelerometers positioned on the lower and upper trunk, and symptoms and functional limitations were assessed with standardized self-report measures. The 4 included patients had symptoms of severe dizziness that had lasted more than 1 year after the onset of vestibular dysfunction and a moderate level of perceived disability. Musculoskeletal abnormalities typically included postural misalignment, restricted abdominal respiration, restricted trunk movements, and tense muscles of the upper trunk and neck. The patients attended a modified vestibular rehabilitation program consisting of body awareness exercises addressing posture, movements, and respiration. After the intervention, self-reported symptoms and perceived disability improved. Improvements in mobility and positive physical changes were found in the upper trunk and respiratory movements. The attenuation of mediolateral accelerations (ie, body oscillations) in the upper trunk changed; a relatively more stable upper trunk and a concomitantly more flexible lower trunk were identified during walking in 3 patients. The recovery process may be influenced by self-inflicted rigid body movements and behavior strategies that prevent compensation. Addressing physical dysfunction and enhancing body awareness directly and dizziness indirectly may help patients with unilateral vestibular hypofunction break a self-sustaining cycle of dizziness and musculoskeletal problems. Considering the body as a functional unit and including both musculoskeletal and vestibular systems in examination and treatment may be

Different types of working memory binding in epilepsy patients with unilateral anterior temporal lobectomy.

The medial temporal lobe is an important structure for long-term memory formation, but its role in working memory is less clear. Recent studies have shown hippocampal involvement during working memory tasks requiring binding of information. It is yet unclear whether this is limited to tasks containing spatial features. The present study contrasted three binding conditions and one single-item condition in patients with unilateral anterior temporal lobectomy. A group of 43 patients with temporal lobectomy (23 left; 20 right) and 20 matched controls were examined with a working memory task assessing spatial relational binding (object-location), non-spatial relational binding (object-object), conjunctive binding (object-colour) and working memory for single items. We varied the delay period (3 or 6s), as there is evidence showing that delay length may modulate working memory performance. The results indicate that performance was worse for patients than for controls in both relational binding conditions, whereas patients were unimpaired in conjunctive binding. Single-item memory was found to be marginally impaired, due to a deficit on long-delay trials only. In conclusion, working memory binding deficits are found in patients with unilateral anterior temporal lobectomy. The role of the medial temporal lobe in working memory is not limited to tasks containing spatial features. Rather, it seems to be involved in relational binding, but not in conjunctive binding. The medial temporal lobe gets involved when working memory capacity does not suffice, for example when relations have to be maintained or when the delay period is long. Copyright © 2014 Elsevier Inc.

AIM: To investigate the effect of pain relief after infusion of ropivacaine at port sites at the end of surgery. METHODS: From October 2006 to September 2007, 72 patients undergoing laparoscopic cholecystectomy (LC) were randomized into two groups of 36 patients. One group received ropivacaine infusion at the port sites at the end of LC and the other received normal saline. A visual analog scale was used to assess postoperative pain when the patient awakened in the operating room, 6 and 24 h after surgery, and before discharge. The amount of analgesics use was also recorded. The demographics, laboratory data, hospital stay, and perioperative complications were compared between the two groups. RESULTS: There was no difference between the two groups preoperatively in terms of demographic and laboratory data. After surgery, similar operation time, blood loss, and no postoperative morbidity and mortality were observed in the two groups. However, a significantly lower pain score was observed in the patients undergoing LC with local anesthesia infusion at 1 h after LC and at discharge. Regarding analgesic use, the amount of meperidine used 1 h after LC and the total used during admission were lower in patients undergoing LC with local anesthesia infusion. This group also had a shorter hospital stay. CONCLUSION: Local anesthesia with ropivacaine at the port site in LC patients significantly decreased postoperative pain immediately. This explains the lower meperidine use and earlier discharge for these patients. PMID:19452582

An increasing number of studies have been conducted to apply unilateral balloon kyphoplasty in the treatment of ostroporotic vertebral compression fractures (OVCFs). However, the efficacy and safety of unilateral kyphoplasty and whether a unilateral or a bilateral approach is superior is controversial. The purpose of this study was to evaluate the role of unilateral balloon kyphoplasty and use meta-analysis to compare the efficacy and safety of unilateral and bilateral kyphoplasty in patients with OVCFs. A systematic literature search was conducted from 1970 to April 2017 using Medline database and the Cochrane Central Register of Controlled Trials. Articles were limited to those published in English. Randomized controlled trials and nonrandomized comparative studies were also included. The following search terms were used: "osteoporotic vertebral compression fractures," or "OVCF," and "unilateral kyphoplasty," or "unipedicular approach," or "single balloon kyphoplasty," or "one balloon kyphoplasty." A comprehensive search of reference lists of retrieved articles and previous published reviews was also performed to ensure inclusion of all possible studies. All potential articles were independently reviewed by 2 investigators for inclusion into the final analysis. MINORS score was used for nonrandomized studies, and Detsky quality index was applied for prospective randomized controlled trials. Systematic review and meta-analysis was performed for the included studies. After unilateral balloon kyphoplasty the mean postoperative visual analog score (VAS) was from 1.74 to 4.77, mean postoperative kyphotic angle was from 5.9º to 11.22º, and complications involving cement leaks was from 6.8 to 21.9% or adjacent level fractures was from 0 to 5.6%). Unilateral kyphoplasty had significantly lower operative time, and less bone cement volume; however, the postoperative VAS, Oswestry Disability Index (ODI), vertebral height restoration rate, and cement leakage and adjacent

Cardiovascular mortality is the leading cause of death in patients with prostate cancer (PC), metabolic syndrome (MS) being related to it. The main objective of this study was to determine the prevalence of MS in patients with CP undergoing androgen suppression (AS). We performed a retrospective study of cases and controls that included 159 patients. The study group was made up of 53 patients with PC undergoing SA for a period exceeding 12 months. The control group was formed by 53 patients with PC at the time of diagnosis and 53 patients with negative prostate biopsy. All patients were evaluated for presence of MS according to NCEP-ATPIII criteria. Prevalence of MS in patients without PC was 32.1% and in those with non-treated PC 35.8%, P = .324. In patients with PC undergoing AS, prevalence of MS was 50.9%, P < .001. When AS duration was less than 36 months, prevalence of MS was 44.0% and when greater than 36 months 57.1%, P < .001. Waist circumference and hyperglycemia were the two MS components that significantly increased. AS and its duration were independent predictors factors for the development of MS. Continuous AS therapy increases the prevalence of MS and especially waist circumference and hyperglycemia. Development of MS increases according to AS duration. Copyright © 2013 AEU.

We aimed to investigate mastication predominance in healthy dentate individuals and patients with unilateral posterior missing teeth using objective and subjective methods. The sample comprised 50 healthy dentate individuals (healthy dentate group) and 30 patients with unilateral posterior missing teeth (partially edentulous group). Subjects were asked to freely chew three kinds of test foods (peanuts, beef jerky and chewing gum). Electromyographic activity of the bilateral masseter muscles was recorded. The chewing side (right side or left side) was judged by the level of root mean square electromyographic amplitude. Mastication predominance was then objectively assessed using the mastication predominant score and the mastication predominant index. Self-awareness of mastication predominance was evaluated using a modified visual analogue scale. Mastication predominance scores of the healthy dentate and partially edentulous groups for each test food were analysed. There was a significant difference in the distribution of the mastication predominant index between the two groups (P < 0·05). The mastication predominant score was weakly correlated with self-awareness of mastication predominance in the healthy dentate group, whereas strong correlation was observed in the partially edentulous group (P < 0·05). The results suggest that the individuals with missing unilateral posterior teeth exhibited greater mastication predominance and were more aware of mastication predominance than healthy dentate individuals. Our findings suggest that an objective evaluation of mastication predominance is more precise than a subjective method. © 2016 John Wiley & Sons Ltd.

Objective: We explored the effectiveness of mirror therapy (MT) in the treatment of unilateral neglect in stroke patients. Methods: This is an open, blinded endpoint, randomized controlled trial carried out from January 2011 to August 2013. We included stroke patients with thalamic and parietal lobe lesions with unilateral neglect 48 hours after stroke. Patients were randomized to the MT group or the control group (sham MT), and both the groups received limb activation. Patients received treatment for 1–2 hours a day 5 days a week for 4 weeks. The primary outcome was unilateral neglect assessed by a blinded assessor using the star cancellation test, the line bisection test, and a picture identification task at 1, 3, and 6 months. This study was registered at http://clinicaltrials.gov (NCT 01735877). Results: Forty-eight patients were randomized to MT (n = 27) or the control group (n = 21). Improvement in scores on the star cancellation test over 6 months was greater in the MT group (mean difference 23, 95% confidence interval [CI] 19–28; p < 0.0001). Similarly, improvement in the MT group was observed in the scores on the picture identification task (mean difference 3.2, 95% CI 2.4–4.0; p < 0.0001) and line bisection test (mean difference 8.6, 95% CI 2.7–14.6; p = 0.006). Conclusions: In patients with stroke, MT is a simple treatment that improves unilateral neglect. Classification of evidence: This study provides Class I evidence that for patients with neglect from thalamic and parietal lobe strokes, MT improves neglect. PMID:25107877

2016-10-01

In cases were the deep inferior epigastric perforator flap (DIEP flap) is not available and unilateral transverse myocutaneous gracilis flap (TMG flap) is not sufficient for breast reconstruction, we perform double TMG flaps as a reconstructive method. In this report, we present our results of the use of double TMG free-flap-transfer for unilateral breast reconstruction. Between August 2004 and June 2012 we performed 58 TMG flaps in 29 patients for unilateral breast reconstruction. Patient data were analyzed and operative outcome (operation time, complication rate and aesthetic results) were investigated. Aesthetic outcome was evaluated retrospectively via photo documentation by an independent plastic surgeon. The results were classified in;unsatisfactory, satisfactory, good and very good. The average operating time was 6 hours 55 minutes (295 - 650 minutes). Of 58 TMG flaps, 57 (98.3%) were successful. Thrombosis occurred in seven (12%) cases (1 arterial, 6 venous). Flap salvage was successful in six cases and flap failure occurred in one (1.7%) case. The results of 25 patients were graded as good and very good. Three patients showed satisfying and one patient unsatisfying results. Double TMG flaps in unilateral breast reconstruction could lead to good operative results. This method further expands the range of options with autologous tissue in reconstructive breast surgery. © 2015 Wiley Periodicals, Inc. Microsurgery 36:539-545, 2016. © 2015 Wiley Periodicals, Inc.

Purpose Obesity can result in increased blood loss, which is correlated with poor prognosis in total knee arthroplasty (TKA). Clinical application of tranexamic acid is effective in reducing blood loss in TKA. However, most previous studies focused on the effect of tranexamic acid in the whole population, neglecting patients with specific health conditions, such as obesity. We hypothesized that tranexamic acid would reduce blood loss to a greater extent in obese patients than in those of normal weight. Patients and methods A total of 304 patients with knee osteoarthritis treated with TKA from October 2013 to March 2015 were separated into tranexamic, non-tranexamic, obese, and non-obese groups. The demographic characteristics, surgical indices, and hematological indices were all recorded. We first investigated the ability of intravenous tranexamic acid to reduce intraoperative blood loss in knee osteoarthritis patients undergoing unilateral TKA. Second, we performed subgroup analysis to compare the effects of tranexamic acid between obese and non-obese patients separately. Results Of the 304 patients, 146 (52.0%) received tranexamic acid and 130 (42.8%) were obese. In the analysis of the whole group, both the actual and occult blood loss volume were lower in the tranexamic acid group (both P < 0.05). Tourniquet time was shorter in the tranexamic acid group (P < 0.05). In subgroup analysis, tranexamic acid was shown to reduce theoretical and actual blood loss in both the obese and non-obese groups (P < 0.05). Tranexamic acid reduced occult blood loss and tourniquet time in the obese group (P < 0.05), while no such effects were observed in the non-obese group (P > 0.05). Conclusion Tranexamic acid can reduce occult blood loss and tourniquet time in obese patients to a greater extent than in patients of normal weight. Therefore, obese knee osteoarthritis patients undergoing TKA can benefit more from tranexamic acid. PMID:29695912

To report a patient with unilateral glaucoma associated with Sotos syndrome. Sotos syndrome (cerebral gigantism) is a disorder of growth and development with characteristic facial changes and normal endocrine function. Ocular manifestations may also include megalocornea, iris hypoplasia, cataracts, megalophthalmos, strabismus, nystagmus, and retinal dystrophy. Case report. A 50 year-old man with the clinical features of Sotos syndrome presented with complaints of decreased vision in the left eye. Ophthalmologic examination revealed bilateral megalocornea, megalophthalmos, iris hypoplasia and transillumination defects, cataracts, and unilateral glaucoma. Intraocular pressure was lowered, and visual field loss was stabilized with topical medications. Sotos syndrome patients should be examined routinely to allow for early detection and treatment of potential ocular problems, including glaucoma.

This study aims to describe the rate and characteristics of transient renal impairment in unilateral ureteric stone patients without chronic kidney disease (CKD) and to identify factors that may have influenced renal function of these patients. Unilateral ureteric stone patients who visited our hospital's emergency department from December, 2009 to December, 2015 were divided into two groups based on estimated glomerular filtration rate (eGFR): group I (patients with eGFR ≥ 60 ml/min/1.73 m 2 ) and group II (eGFR < 60 ml/min/1.73 m 2 ). A univariate comparison between groups I and II was performed. Multivariable logistic regression analysis was performed to determine factors that influenced renal function. There were 107 patients in group II, which constituted 5.6 % of the total patients. In the multivariable logistic regression analysis, age (p < 0.001, odds ratio [OR] = 1.069, confidence interval [CI] = 1.049-1.089), hypertension (p < 0.001, OR = 2.302, CI = 1.467-3.611), stone size (p = 0.001, OR = 1.141, CI = 1.057-1.231), white blood cell count (p = 0.001, OR = 1.132, CI = 1.055-1.215) and hematuria (p < 0.001, OR = 0.383, CI = 0.231-0.636) were found to be independent factors for renal impairment. Based on the results of this study, the rate of renal impairment was 6 % of the unilateral ureteric stone patients without pre-existing CKD. Age and hypertension were found to be independent factors for renal impairment; NSAIDs should be used cautiously or other agents for pain relief such as opioids should be considered in old aged patients with hypertension.

We describe isolated unilateral axial weakness in three patients eventually diagnosed with anterior cerebral artery infarction (ACAI), a new clinical observation. Files of three ACAI patients (2 females, 1 male, ages 55-80) were retrospectively reviewed. All three presented to the ED with sudden unsteadiness. On initial neurological examination, all three patients manifested unilateral truncal deviation to the side contralateral to the weakness, even while seated. There was significant unilateral hypotonia due to substantial paravertebral weakness. None had pyramidal signs or increased limb tone. Speech, language, and cognitive performance were intact during admission examination. In all three patients, initial diffusion-weighted imaging (DWI) MRI showed small confined regions of restriction involving the posterolateral border of ACA territory; CT angiography was normal in one patient with a newly diagnosed atrial fibrillation but showed atherosclerotic vasculature with severe narrowing of the A3 segment of the ACA in two. Awareness of ACAI presenting as unilateral axial weakness is warranted. We suggest that optimal diagnostic management should include examination of axial tone. Ischemic involvement of distal ACA branches may herald a more extensive ACAI. Prompt diagnosis may enable thrombolysis or endovascular treatment, and blood pressure maintenance may allow adequate perfusion to damaged tissue. Copyright © 2016 Elsevier B.V. All rights reserved.

Unilateral proptosis as the initial manifestation of malignancy.

Proptosis, a common sign with a broad differential diagnosis, is defined as anterior displacement and protrusion of one or both orbital globes. Patients can present with varying degrees of chronicity, visual loss and associated symptoms. The etiology of acquired unilateral proptosis is diverse, ranging from benign to life-threatening. The causes of unilateral proptosis include traumatic, vascular, endocrine, inflammatory, infective and malignant. Breast carcinoma is the most common metastatic cause of proptosis; however, proptosis has never been reported as the initial manifestation of breast carcinoma. Our patient presented with unilateral proptosis secondary to an intraorbital lesion and histopathology of orbital lesion was suggestive of metastatic breast adenocarcinoma. She was later diagnosed to have primary breast carcinoma. We present this unusual case of a 56-year-old woman who presented with proptosis as the initial manifestation of a metastatic breast malignancy.

Tranexamic acid reduces the risk of bleeding among patients undergoing cardiac surgery, but it is unclear whether this leads to improved outcomes. Furthermore, there are concerns that tranexamic acid may have prothrombotic and proconvulsant effects. In a trial with a 2-by-2 factorial design, we randomly assigned patients who were scheduled to undergo coronary-artery surgery and were at risk for perioperative complications to receive aspirin or placebo and tranexamic acid or placebo. The results of the tranexamic acid comparison are reported here. The primary outcome was a composite of death and thrombotic complications (nonfatal myocardial infarction, stroke, pulmonary embolism, renal failure, or bowel infarction) within 30 days after surgery. Of the 4662 patients who were enrolled and provided consent, 4631 underwent surgery and had available outcomes data; 2311 were assigned to the tranexamic acid group and 2320 to the placebo group. A primary outcome event occurred in 386 patients (16.7%) in the tranexamic acid group and in 420 patients (18.1%) in the placebo group (relative risk, 0.92; 95% confidence interval, 0.81 to 1.05; P=0.22). The total number of units of blood products that were transfused during hospitalization was 4331 in the tranexamic acid group and 7994 in the placebo group (P<0.001). Major hemorrhage or cardiac tamponade leading to reoperation occurred in 1.4% of the patients in the tranexamic acid group and in 2.8% of the patients in the placebo group (P=0.001), and seizures occurred in 0.7% and 0.1%, respectively (P=0.002 by Fisher's exact test). Among patients undergoing coronary-artery surgery, tranexamic acid was associated with a lower risk of bleeding than was placebo, without a higher risk of death or thrombotic complications within 30 days after surgery. Tranexamic acid was associated with a higher risk of postoperative seizures. (Funded by the Australian National Health and Medical Research Council and others; ATACAS Australia New Zealand

Obesity can result in increased blood loss, which is correlated with poor prognosis in total knee arthroplasty (TKA). Clinical application of tranexamic acid is effective in reducing blood loss in TKA. However, most previous studies focused on the effect of tranexamic acid in the whole population, neglecting patients with specific health conditions, such as obesity. We hypothesized that tranexamic acid would reduce blood loss to a greater extent in obese patients than in those of normal weight. A total of 304 patients with knee osteoarthritis treated with TKA from October 2013 to March 2015 were separated into tranexamic, non-tranexamic, obese, and non-obese groups. The demographic characteristics, surgical indices, and hematological indices were all recorded. We first investigated the ability of intravenous tranexamic acid to reduce intraoperative blood loss in knee osteoarthritis patients undergoing unilateral TKA. Second, we performed subgroup analysis to compare the effects of tranexamic acid between obese and non-obese patients separately. Of the 304 patients, 146 (52.0%) received tranexamic acid and 130 (42.8%) were obese. In the analysis of the whole group, both the actual and occult blood loss volume were lower in the tranexamic acid group (both P < 0.05). Tourniquet time was shorter in the tranexamic acid group ( P < 0.05). In subgroup analysis, tranexamic acid was shown to reduce theoretical and actual blood loss in both the obese and non-obese groups ( P < 0.05). Tranexamic acid reduced occult blood loss and tourniquet time in the obese group ( P < 0.05), while no such effects were observed in the non-obese group ( P > 0.05). Tranexamic acid can reduce occult blood loss and tourniquet time in obese patients to a greater extent than in patients of normal weight. Therefore, obese knee osteoarthritis patients undergoing TKA can benefit more from tranexamic acid.

This study aimed to evaluate the benefits of Arnica montana on post-operative blood loss and seroma production in women undergoing unilateral total mastectomy by administering Arnica Montana 1000 Korsakovian dilution (1000 K). From 2012 to 2014, 53 women were randomly assigned to A. montana or placebo and were followed up for 5 days. The main end point was the reduction in blood and serum volumes collected in drainages. Secondary end points were duration of drainage, a self-evaluation of pain, and the presence of bruising or hematomas. The per-protocol analysis revealed a lower mean volume of blood and serum collected in drainages with A. montana (-94.40 ml; 95% confidence interval [CI]: 22.48-211.28; P = 0.11). A regression model including treatment, volume collected in the drainage on the day of surgery, and patient weight showed a statistically significant difference in favor of A. montana (-106.28 ml; 95% CI: 9.45-203.11; P = 0.03). Volumes collected on the day of surgery and the following days were significantly lower with A. montana at days 2 ( P = 0.033) and 3 ( P = 0.0223). Secondary end points have not revealed significant differences. A. montana 1000 K could reduce post-operative blood and seroma collection in women undergoing unilateral total mastectomy. Larger studies are needed with different dilutions of A. montana to further validate these data.

With the transition from infectious disease and acute illness to chronic disease and degenerative illness as leading causes of death, health-related quality of life has become an important aspect in assessing the burden of chronic disease. The quality of life of haemodialysis patients has been studied extensively; however, very limited research using exploratory descriptive design has been carried out in this area in China. The aim of this study was to explore health-related quality of life of end-stage renal disease patients undergoing haemodialysis in China. This study used the qualitative research design approach. A semi-structured, in-depth interview was conducted with 16 haemodialysis patients in two hospitals using Colaizzi's phenomenological method to transcribe and analyse the data. The results of this study showed that dialysis patients show improvement in physical competence, but they also experienced emotional instability and psychological distress, financial burdens, inadequate disease knowledge and less social support which influenced their quality of life. To optimise the patients undergoing dialysis health-related quality of life, support of psycho-social-economical aspects should be enhanced. Health care providers should give haemodialysis patients thorough health education, individualised psychological and emotional intervention and adequate social support to optimise health-related quality of life.

Head-shaking nystagmus predicts greater disability in unilateral peripheral vestibulopathy.

The objective of this study was to determine the association of the bedside test of head-shaking nystagmus (HSN) with patients' self-perceived dizziness handicap as well as this test's sensitivity and specificity in unilateral peripheral vestibular hypofunction. A retrospective case-control study was performed. The study was held at an academic, tertiary referral center. Fifty-three adult patients with unilateral peripheral hypofunction defined by the caloric test of the videonystagmography with documented bedside HSN and who had completed questionnaires of self-perceived dizziness handicap were included. The sensitivity and specificity of the bedside HSN in patients and 10 healthy controls in diagnosing unilateral vestibular hypofunction defined by videonystagmographic caloric testing and by abnormal gain and symmetry of the vestibular-ocular reflex by rotary chair testing were determined. Scores of the screening test of the Dizziness Handicap Index and Functional Level Scale questionnaires were taken. When using the caloric irrigation test as the reference standard for unilateral vestibular hypofunction, the sensitivity, specificity, and positive predictive value of the bedside HSN were 31%, 96%, and 97%, respectively. When comparing with results of rotational chair testing (vestibular-ocular reflex gain and symmetry), the sensitivity of the HSN test increases to 71%. Patients with positive bedside HSN had higher scores (greater self-perceived dizziness handicap) of the Dizziness Handicap Index (P = .049) and higher (worse) scores of the Functional Level Scale (P = .0377) than those with negative bedside HSN (Wilcoxon rank test). Greater perceived handicap was correlated with a positive bedside HSN in patients with unilateral peripheral vestibulopathy. The HSN has sufficient sensitivity to be used as screening test of uncompensated vestibulopathy in this series. However, a negative HSN alone does not rule out the diagnosis of peripheral vestibular dysfunction

Unilateral Punctate Keratitis Secondary to Wallenberg Syndrome

We studied three patients who developed left unilateral punctate keratitis after suffering left-sided Wallenberg Syndrome. A complex evolution occurred in two of them. In all cases, neurophysiological studies showed damage in the trigeminal sensory component at the bulbar level. Corneal involvement secondary to Wallenberg syndrome is a rare cause of unilateral superficial punctate keratitis. The loss of corneal sensitivity caused by trigeminal neuropathy leads to epithelial erosions that are frequently unobserved by the patient, resulting in a high risk of corneal-ulcer development with the possibility of superinfection. Neurophysiological studies can help to locate the anatomical level of damage at the ophthalmic branch of the trigeminal nerve, confirming the suspected etiology of stroke, and demonstrating that prior vascular involvement coincides with the location of trigeminal nerve damage. In some of these patients, oculofacial pain is a distinctive feature. PMID:24882965

Case report: Unilateral conduction hearing loss due to central venous occlusion.

Central venous stenosis is a well-known complication in patients with vascular access for hemodialysis. We report two cases involving patients on hemodialysis with arteriovenous fistulas who developed reversible unilateral conductive hearing loss secondary to critical stenosis of central veins draining the arteriovenous dialysis access. A proposed mechanism for the patients' reversible unilateral hearing loss is pterygoid venous plexus congestion leading to decreased Eustachian tube patency. Endovascular therapy was conducted to treat the stenosis and the hearing loss of both patients was returned to near normal after successful central venous angioplasty.

Objective To determine the dose of hyperbaric bupivacaine 0.5% required for unilateral spinal anesthesia during diagnostic knee arthroscopy. Patients and methods This prospective, randomized, clinical study was performed in 80 patients who were assigned to four groups to receive different doses of intrathecal hyperbaric bupivacaine (5 mg, 7.5 mg, 10 mg and 12.5 mg in Groups 1, 2, 3, and 4 respectively). Onset of sensory and motor block, hemodynamic changes, regression of motor block, and incidence of complications were recorded. Results Unilateral sensory block was reported in 90% and 85% of patients in Group 1 and Group 2, respectively, but not in any patient in Group 3 and Group 4. Unilateral motor block (modified Bromage scale 0) was reported in 95% of patients in Group 1, 90% in Group 2, and only 5% in Group 3, while no patient in Group 4 showed unilateral motor block. The time required for regression of motor block (Bromage scale 0) was prolonged with higher doses. The incidence of nausea, vomiting, and urine retention was similar in the study groups. Conclusion Unilateral sensory and motor block can be achieved with doses of 5 mg and 7.5 mg hyperbaric bupivacaine 0.5% with a stable hemodynamic state. However, 7.5 mg of hyperbaric bupivacaine 0.5% was the dose required for adequate unilateral spinal anesthesia. PMID:22915874

To compare the effects of tramadol alone, or in combination with dipyrone or meloxicam, on postoperative pain and analgesia requirement after unilateral mastectomy with or without ovariohysterectomy in dogs. Prospective, randomized, clinical study. Twenty seven bitches undergoing unilateral mastectomy with or without ovariohysterectomy. Anesthesia was induced with propofol and maintained with isoflurane and a constant rate infusion of morphine. Before the end of surgery, dogs were randomly assigned to receive intravenous tramadol alone (3 mg kg(-1), group T), combined with dipyrone (30 mg kg(-1), group TD) or meloxicam (0.2 mg kg(-1), group TM). Dogs received additional doses of tramadol (groups T and TM) or tramadol with dipyrone (group TD) at 8 and 16 hours after extubation. Postoperative pain was assessed by a blinded observer before anesthesia (baseline) and at 1, 2, 3, 4, 6, 8, 12, 16 and 24 hours after extubation using a visual analog scale (VAS) and a modified Glasgow scale. Rescue analgesia (morphine, 0.5 mg kg(-1)) was administered if the Glasgow pain score was >3.5. There were no significant differences among groups in pain scores evaluated by the VAS or the Glasgow scale. In groups T, TD and TM, pain scores were significantly higher than at baseline for 6, 8 and 2 hours, respectively. Rescue analgesia was administered to 3/9, 2/9 and 1/9 dogs in groups T, TD and TM, respectively (p > 0.05) [Correction added on 15 August 2013, after first online publication: 'T, TM and TD' was changed to 'T, TD and TM'.]. Under the conditions of this study, tramadol alone or in combination with dypyrone or meloxicam provided effective analgesia for 24 hours in most dogs after unilateral mastectomy with or without ovariohysterectomy. Further evaluation of combination therapies is needed in larger groups of dogs. © 2013 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

Epilepsy surgery in patients with malformations of cortical development.

Lüders, Hans; Schuele, Stephan U

2006-04-01

Patients with malformations of cortical development often suffer from intractable focal epilepsy. This review considers recent progress in the selection and seizure outcome of patients undergoing resective epilepsy surgery for this condition. Patients with malformations of cortical development restricted to part or even a whole hemisphere may be candidates for epilepsy surgery even when, due to microscopic malformations, magnetic resonance imaging shows no detectable lesion. Despite recent advances in structural and functional imaging, the majority of patients with this condition undergo invasive evaluation. Patients with focal cortical dysplasia, with and without a detectable lesion on magnetic resonance imaging, often have a favorable outcome with epilepsy surgery. The underlying pathological substrate seems to be a better predictor for surgical outcome in patients with focal cortical dysplasia than the presence of a lesion on magnetic resonance imaging. Epilepsy surgery can be offered in a highly selected subgroup of patients with unilateral nodular heterotopia. Seizures in hemimegalencephaly may respond favorably to hemispherectomy, although most children will continue to have seizures and significant functional impairments. Patients with focal epilepsy due to malformations of cortical development are often intractable to medical management. Resective epilepsy surgery can be beneficial, particularly for patients with focal cortical dysplasia and unilateral hemispheric malformations.

2013-07-01

We evaluated the incidence and characteristics of hyperventilation-induced nystagmus (HVN) in 49 patients with gadolinium-enhanced magnetic resonance imaging evidence of vestibular schwannoma and 53 patients with idiopathic unilateral sensorineural hearing loss and normal radiological findings. The sensitivity and specificity of the hyperventilation test were compared with other audio-vestibular diagnostic tests (bedside examination of eye movements, caloric test, auditory brainstem responses) in the two groups of patients. The hyperventilation test scored the highest diagnostic efficiency (sensitivity 65.3 %; specificity 98.1 %) of the four tests in the differential diagnosis of vestibular schwannoma and idiopathic unilateral sensorineural hearing loss. Small tumors with a normal caloric response or caloric paresis were associated with ipsilateral HVN and larger tumors and severe caloric deficits with contralateral HVN. These results confirm that the hyperventilation test is a useful diagnostic test for predicting vestibular schwannoma in patients with unilateral sensorineural hearing loss.

Context This article discusses the anesthetic considerations in patients undergoing bariatric surgery in the preoperative, intraoperative, and postoperative phases of surgery. Evidence Acquisition This review includes studies involving obese patients undergoing bariatric surgery. Searches have been conducted in PubMed, MEDLINE, EMBASE, Google Scholar, Scopus, and Cochrane Database of Systematic Review using the terms obese, obesity, bariatric, anesthesia, perioperative, preoperative, perioperative, postoperative, and their combinations. Results Obesity is a major worldwide health problem associated with many comorbidities. Bariatric surgery has been proposed as the best alternative treatment for extreme obese patients when all other therapeutic options have failed. Conclusions Anesthetists must completely assess the patients before the surgery to identify anesthesia- related potential risk factors and prepare for management during the surgery. PMID:29430407

This study was designed to investigate the effects of aromatherapy on pruritus in patients with chronic renal failure undergoing hemodialysis. The participants were 29 adult patients living in Seoul, Korea. Thirteen patients were assigned to the experimental group and received the aromatherapy massage on the arm 3 times a week for 4 weeks. Pruritus score, skin pH, stratum corneum hydration, and pruritus-related biochemical markers were measured before and after the treatment. The results showed that pruritus score was significantly decreased after aromatherapy. Skin pH showed no significant changes in either group while stratum corneum hydration increased significantly in the experimental group after aromatherapy. The results support the use aromatherapy as a useful and effective method of managing pruritus in patients undergoing hemodialysis.

Dermatological Manifestations in Patients Undergoing In Vitro Fertilisation: A Prospective Study.

Changing sociodemographic patterns with an increase in the age of childbirth have affected fertility rates worldwide. With advancing reproductive medicine, assisted reproductive techniques (ARTs) are becoming common. While dermatological manifestations in normal pregnancies have been well documented, there is a paucity of data regarding cutaneous manifestations in patients undergoing ART. The objectives of our study were to estimate the incidence and types of dermatological manifestations in patients undergoing in vitro fertilisation (IVF) and to study their associations with age, type of infertility, and outcome of the procedure. A prospective cohort of 200 patients undergoing IVF in a tertiary care centre was observed for occurrence of any dermatological manifestations from initiation of the IVF protocol to the outcome of the procedure at 3 weeks after embryo transfer. Dermatological manifestations were seen in 27% of the study group, with urticaria being the most common cutaneous finding seen in 13.5%, followed by acneform eruptions (3%). Twenty-six (96.3%) of patients who manifested with urticaria were on progesterone. No statistically significant association was found between the occurrence of dermatological manifestations and the outcome of IVF, type of infertility, history of ART, and ovum donation in our study. Association between the age of the patient and the outcome of IVF cycle was statistically significant. Dermatological manifestations are seen in almost one-quarter of patients undergoing IVF, with progesterone-induced urticaria being the most common. Occurrence of cutaneous manifestations has no significant association with the outcome of IVF.

The Baking Tray Task is a comprehensible, simple-to-perform test for use in assessing unilateral neglect. The aim of this study was to validate further its use with stroke patients. The Baking Tray Task was compared with 2 versions of the Behaviour Inattention Test and a test for personal neglect. A total of 270 patients were subjected to a 3-item version of the Behaviour Inattention Test and 40 patients were subjected to an 8-item version of the Behaviour Inattention Test, besides the Baking Tray Task and the personal neglect test. The Baking Tray Task was more sensitive than the 3-item Behaviour Inattention Test, but the 8-item Behaviour Inattention Test was more sensitive than the Baking Tray Task. The best combination of any 3 tests was Baking Tray Task, Reading an article, and Figure copying; the 2 last-mentioned being a part of the 8-item Behaviour Inattention Test. Multi-item tests detect more cases of neglect than do single tests. However, it is tiresome for the patient to undergo a larger test battery than necessary. It is also time-consuming for the staff. Behavioural tests seem more appropriate when assessing neglect. The Baking Tray Task seems to be one of the most sensitive single tests, but its sensitivity can be further enhanced when it is used in combination with other tests.

Glomerular filtration rate (GFR) has been reported to decrease after unilateral adrenalectomy in patients with primary aldosteronism (PA). The aim of this study was to identify clinical predictors for decreased GFR after adrenalectomy in patients with PA. The records of 187 patients (98 patients with PA and 89 with non-PA adrenal disease) who were followed up for at least 6 months after unilateral adrenalectomy were retrospectively analyzed. Estimated GFR (eGFR) was investigated at 1, 3, and 6 months postoperatively. Preoperative risk factors for eGFR% decline at 1 month ([preoperative eGFR-eGFR at 1 month]/preoperative eGFR × 100) and postoperative CKD development were investigated. The eGFR decreased significantly at 1 month and remained stable in the PA group. However, there were no significant changes in eGFR in the non-PA group over the 6-month period. In the PA group, a high preoperative eGFR and high aldosterone to renin ratio (ARR) were independently associated with eGFR% decline at 1 month. In patients with PA but without preoperative CKD (n = 68), a low preoperative eGFR and high ARR were independent risk factors for developing postoperative CKD. The best preoperative cut-off values of eGFR and ARR for predicting the development of postoperative CKD were ≤ 102 ml/min/1.73 m 2 and ≥ 448 ng/dl:ng/ml/h, respectively. Renal function deteriorated significantly after unilateral adrenalectomy in patients with PA. Clinicians must pay attention to postoperative renal function in PA patients at elevated risk of developing decreased kidney function.

Sinusitis in patients undergoing allogeneic bone marrow transplantation - a review.

Sinusitis is a common morbidity in general population, however little is known about its occurrence in severely immunocompromised patients undergoing allogeneic hematopoietic stem cell transplantation. The aim of the study was to analyze the literature concerning sinusitis in patients undergoing allogeneic bone marrow transplantation. An electronic database search was performed with the objective of identifying all original trials examining sinusitis in allogeneic hematopoietic stem cell transplant recipients. The search was limited to English-language publications. Twenty five studies, published between 1985 and 2015 were identified, none of them being a randomized clinical trial. They reported on 31-955 patients, discussing different issues i.e. value of pretransplant sinonasal evaluation and its impact on post-transplant morbidity and mortality, treatment, risk factors analysis. Results from analyzed studies yielded inconsistent results. Nevertheless, some recommendations for good practice could be made. First, it seems advisable to screen all patients undergoing allogeneic hematopoietic stem cell transplantation with Computed Tomography (CT) prior to procedure. Second, patients with symptoms of sinusitis should be treated before hematopoietic stem cell transplantation (HSCT), preferably with conservative medical approach. Third, patients who have undergone hematopoietic stem cell transplantation should be monitored closely for sinusitis, especially in the early period after transplantation.

Neurectomy of the inguinal nerves may be considered for selected refractory cases of chronic postherniorrhaphy inguinal pain (CPIP). There is to date a paucity of easily applicable clinical tools to identify neuropathic pain and examine the neurosensory effects of remedial surgery. The present quantitative sensory testing (QST) pilot study evaluates a sensory mapping technique. Longitudinal (preoperative, immediate postoperative, and late postoperative) dermatomal sensory mapping and a comprehensive QST protocol were conducted in CPIP patients with unilateral, predominantly neuropathic inguinodynia presenting for triple neurectomy (n = 13). QST was conducted in four areas on the affected, painful side and in one contralateral comparison site. QST variables were compared according to sensory mapping outcomes: (o)/normal sensation, (+)/pain, and (-)/numbness. Diagnostic ability of the sensory mapping outcomes to detect QST-assessed allodynia or hypoesthesia was estimated through calculation of specificity and sensitivity values. Preoperatively, patients exhibited mechanical hypoesthesia and allodynia and pressure allodynia and hyperalgesia in painful areas mapped (+) (p < .05); sensory mapping outcome (+) demonstrated high ability to detect mechanical allodynia [sensitivity 0.74 (95% CI 0.61-0.86), specificity 0.94 (0.84-1.00)] and pressure allodynia [sensitivity 0.96 (0.89-1.00), specificity 1.00 (1.00-1.00)], but not thermal allodynia. Postoperatively, mapped areas of numbness (-) were associated with mechanical and thermal hypoesthesia (p < .05); (-) showed high sensitivity and specificity to detect mechanical and cold hypoesthesia. Sensory mapping provides an accurate clinical neuropathic assessment with strong correlation to QST findings of preoperative mechanical and pressure allodynia, and postoperative mechanical and thermal hypoesthesia in CPIP patients undergoing neurectomy.

To systematically review the published clinical trials, case series, and case reports on left unilateral (LUL) electrode placement for clinical electroconvulsive therapy (ECT). PubMed, Ovid Medline, and the Cochrane Library were searched for articles concerning LUL ECT. Number of patients, efficacy, and cognitive outcomes were extracted from the papers that met our inclusion criteria. A total of 52 articles were included in this review, consisting of 33 clinical trials, seven case series, and 12 case reports. Overall, the efficacy of LUL electrode placement for the treatment of depression and psychosis is similar to that of right unilateral (RUL) and bilateral (BL) electrode placements. Patients receiving LUL ECT tend to experience more verbal memory impairment than patients receiving RUL ECT, but less verbal impairment than patients receiving BL ECT. In contrast, patients receiving LUL ECT tended to experience the least visual and nonverbal memory impairment, compared to patients receiving RUL or BL ECT. © 2017 John Wiley & Sons A/S.

To determine the effects of nasoalveolar molding (NAM) on nasal airway architecture. Retrospective case-control study of patients with unilateral cleft lip treated with NAM vs without NAM. Tertiary referral center specializing in cleft and craniofacial care. Patients, Participants, and Interventions: Thirty-six patients with complete unilateral cleft lip and alveolus: 19 with NAM therapy and 17 without NAM therapy. Cone beam computed tomography (CBCT) scans were compared in multiple coronal sections and were evaluated for linear and angular septal deviation, inferior turbinate hypertrophy, and linear and 2-dimensional airway area. There were no significant differences in linear or angular septal deviation, inferior turbinate area, linear stenosis, or airway area between NAM- and non-NAM-treated patients. NAM effectively molds the external nasal cartilage and structures but may have limited effects on internal nasal structures.

Unilateral versus bilateral neck exploration for primary hyperparathyroidism: five-year follow-up of a randomized controlled trial.

To compare long-term patient outcome in a prospective randomized controlled trial between unilateral and bilateral neck exploration for primary hyperparathyroidism (pHPT). Minimal invasive and/or focused parathyroidectomy has challenged the traditional bilateral neck exploration for pHPT. Between 1997 and 2001, we conducted the first unselected randomized controlled trial of unilateral versus bilateral neck exploration for pHPT. The results showed that unilateral exploration is a surgical strategy with distinct advantages in the early postoperative period. However, concerns have been raised that limited parathyroid exploration could increase the risk for recurrent pHPT during long-term follow-up. Ninety-one patients with the diagnosis of pHPT were randomized to unilateral or bilateral neck exploration. Preoperative scintigraphy and intraoperative parathyroid hormone measurement guided the unilateral exploration. Gross morphology and frozen section determined the extent of parathyroid tissue resection in the bilateral group. Follow-up was performed after 6 weeks, 1 year, and 5 years postoperatively. Seventy-one patients were available for 5-year follow-up. There were no differences in serum ionized calcium and parathyroid hormone, respectively, between patients in the unilateral and bilateral group. Overall 6 patients have been found to have persistent (n = 3) or recurrent (n = 3) pHPT; 4 patients in the unilateral group (3 of these 4 patients were bilaterally explored) and 2 patients in the bilateral group. Three of 6 failures were unexpectedly found to have multiple endocrine neoplasia mutations. One patient with solitary adenoma in the bilateral group still required vitamin D substitution 5 years after surgery. Unilateral neck exploration with intraoperative parathyroid hormone assessment provides the same long-term results as bilateral neck exploration, and is thus a valid strategy for the surgical treatment of pHPT.

Our objective was to describe our experience of managing a cohort of adult patients prescribed direct oral anticoagulants (DOACs) undergoing dentoalveolar procedures between November 2012 and May 2016. Prior to conducting a procedure a formal assessment was made of each patient's anticoagulation treatment. A specific plan was then formulated, balancing the risk of bleeding with the risk of thrombosis. Patients received a telephone consultation one week following treatment to assess any post-operative bleeding. Eighty-two patients underwent 111 oral surgical procedures, the majority of which were dental extractions. In the case of 35 (32%) procedures, advice was given to omit the DOAC, either before or after treatment. There was no bleeding following the majority of procedures. Persistent bleeding followed 15 (13.5%) procedures, of which 7 (6.3%) procedures required specific intervention. The majority of patients prescribed DOACs can undergo dentoalveolar procedures safely. Important considerations when planning treatment are: (i) when the patient usually takes their dose of DOAC, (ii) the time the procedure is performed and, (iii) when the DOAC is taken post-procedure. In our experience, if these factors are considered carefully, omission of DOAC doses is unlikely to be required for most patients.

Knowledge of electromyography (EMG) in patients undergoing EMG examinations

Summary The aim of this study was to evaluate knowledge of electromyography (EMG) in patients undergoing the procedure. In one year, 1,586 consecutive patients (mean age 56 years; 58.8% women) were admitted to two EMG labs to undergo EMG for the first time. The patients found to be “informed” about the how an EMG examination is performed and about the purpose of EMG numbered 448 (28.2%), while those found to be “informed” only about the manner of its execution or only about its purpose numbered 161 (10.2%) and 151 (9.5%), respectively. The remaining 826 (52.1%) patients had either no information, or the information they had was very poor or incorrect (this was particularly true if they had been consulting websites). Being “informed” was associated with level of education (high), type of referring physician (specialist) and with an appropriate referral diagnosis specified in the EMG request. The quality of patient information on EMG was found to be very poor and could be improved. Physicians referring patients for EMG examinations, especially general practitioners, should assume primary responsibility for patient education and counseling in this field. PMID:25473740

The American Academy of Orthopaedic Surgeons, in collaboration with the American Dental Association, has developed Appropriate Use Criteria (AUC) for the Management of Patients with Orthopaedic Implants Undergoing Dental Procedures. Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain best outcomes while considering the subtleties and distinctions necessary in making clinical decisions. The Management of Patients with Orthopaedic Implants Undergoing Dental Procedures AUC clinical patient scenarios were derived from indications of patients with orthopaedic implants presenting for dental procedures, as well as from current evidence-based clinical practice guidelines and supporting literature to identify the appropriateness of the use of prophylactic antibiotics. The 64 patient scenarios and 1 treatment were developed by the writing panel, a group of clinicians who are specialists in this AUC topic. Next, a separate, multidisciplinary, voting panel (made up of specialists and nonspecialists) rated the appropriateness of treatment of each patient scenario using a 9-point scale to designate a treatment as Appropriate (median rating, 7 to 9), May Be Appropriate (median rating, 4 to 6), or Rarely Appropriate (median rating, 1 to 3).

Since the advent of optical coherence tomography angiography (OCT-A), nonexudative neovascularization has been described in the fellow eyes of unilateral exudative age-related macular degeneration (AMD). However, there is limited literature describing the natural course and optimal management of these lesions. To determine the incidence of fellow eye involvement in patients presenting with unilateral typical AMD or polypoidal choroidal vasculopathy and to evaluate the patterns of OCT-A changes within 6 months before the onset of exudative changes, especially focusing on nonexudative neovascularization. Data for this study were taken from a prospective, observational cohort study involving Asian patients with exudative AMD in the Asian AMD Phenotyping Study between October 2015 and March 2016. Analyses began in June 2017. Only patients who had gradable OCT-A and indocyanine green angiography (ICGA) scans of the fellow eye at baseline and follow-up at least 6 months apart were included for the analysis. The contralateral eye was evaluated for presence of nonexudative neovascularization based on multimodal imaging, which included ICGA, spectral domain optical coherence tomography, and OCT-A. The difference between the incidence of those with nonexudative choroidal neovascularization and those without as analyzed using log-rank test and qualitative analysis of OCT-A images. We included 95 fellow eyes of 95 patients who presented with unilateral exudative AMD with a mean (SD) age of 68.6 (8.6) years. Nonexudative neovascularization was present in 18 eyes (19%) (8 [22.9%] and 10 [19.0%] fellow eyes with typical AMD and polypoidal choroidal vasculopathy, respectively; 8 [44.4%] on OCT-A; 5 [27.8%] on ICGA; and 5 [27.8%] on both OCT-A and ICGA). Development of exudative changes was noted in 6 fellow eyes (6.3%). Four eyes developed exudation from previously noted nonexudative neovascularization, and 2 eyes arose exudative changes from de novo. The probability of developing

Vancomycin is a commonly used antimicrobial agent for patients undergoing allogeneic hematopoietic stem-cell transplantation (allo-HSCT). Vancomycin has large inter- and intraindividual pharmacokinetic variability, which is mainly described by renal function; various studies have indicated that vancomycin pharmacokinetics are altered in special populations. However, little is known regarding vancomycin pharmacokinetics in patients undergoing allo-HSCT. Therefore, we aimed to develop a population pharmacokinetic (PopPK) model of vancomycin in patients undergoing allo-HSCT for effective and safe antimicrobial therapy and to develop a vancomycin dosing nomogram for a vancomycin optimal-dosing strategy. In total, 285 observations from 95 patients undergoing allo-HSCT were available. The final PopPK parameter estimates were central volume of distribution (V1, L), 39.2; clearance (L/h), 4.25; peripheral volume of distribution (V2, L), 56.1; and intercompartmental clearance (L/h), 1.95. The developed vancomycin model revealed an increase in V1 and V2 compared with those in the general population that consisted of patients with methicillin-resistant Staphylococcus aureus. Moreover, serum creatinine was reduced because of an increase in the plasma fraction because of destruction of hematopoietic stem cells accompanying allo-HSCT pretreatment, suggesting that the Cockcroft-Gault equation-based creatinine clearance value was overestimated. To our knowledge, this is the first PopPK study to develop a dosing nomogram for vancomycin in patients undergoing allo-HSCT and was proven to be useful in optimizing the dosage and dosing interval of vancomycin in these patients. This strategy will provide more useful information for vancomycin therapy with an evidence-based dose adjustment. © 2018, The American College of Clinical Pharmacology.

Objective To identify pain-related behaviors and assess the effects of butorphanol tartrate and morphine sulfate in koi (Cyprinus carpio) undergoing unilateral gonadectomy. Design Prospective study. Animals 90 adult male and female koi. Procedures Each fish received saline (0.9% NaCl) solution (which is physiologically compatible with fish) IM, butorphanol (10 mg/kg [4.5 mg/lb], IM), or morphine (5 mg/kg [2.3 mg/lb], IM) as an injection only (6 fish/treatment); an injection with anesthesia and surgery (12 fish/treatment); or an injection with anesthesia but without surgery (12 fish/treatment). Physiologic and behavioral data were recorded 12 hours before and at intervals after treatment. Results Compared with baseline values, the saline solution–surgery group had significantly decreased respiratory rates (at 12 to 24 hours), food consumption assessed as a percentage of floating pellets consumed (at 0 to 36 hours), and activity score (at 0 to 48 hours). Respiratory rate decreased in all butorphanol-treated fish; significant decreases were detected at fewer time points following morphine administration. In the butorphanol-surgery group, the value for food consumption initially decreased but returned to baseline values within 3 hours after treatment; food consumption did not change in the morphine-surgery group. Surgery resulted in decreased activity, regardless of treatment, with the most pronounced effect in the saline solution–surgery group. Changes in location in water column, interactive behavior, and hiding behavior were not significantly different among groups. Butorphanol and morphine administration was associated with temporary buoyancy problems and temporary bouts of excessive activity, respectively. Conclusions and Clinical Relevance Butorphanol and morphine appeared to have an analgesic effect in koi, but morphine administration caused fewer deleterious adverse effects. Food consumption appeared to be a reliable indicator of pain in koi. PMID:24004238

Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity. Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.e. the infiltration of myenteric ganglions by inflammatory cells) in patients undergoing surgery for this condition. We analyzed archival resection samples from the proximal resection margins of 165 patients undergoing left hemicolectomy (60 emergency and 105 elective surgeries) for colonic diverticulitis, by histology and immunochemistry. Overall, plexitis was present in almost 40% of patients. It was subdivided into an eosinophilic (48%) and a lymphocytic (52%) subtype. Plexitis was more frequent in younger patients; and it was more frequent in those undergoing emergency surgery (50%), compared to elective (28%) surgery (p = 0.007). All the severe cases of plexitis displayed the lymphocytic subtype. In conclusion, myenteric plexitis is frequent in patients with colonic diverticular disease needing surgery, and it might be implicated in the pathogenesis of the disease.

The aim of this study was to compare the clinical effects and characteristics of hyperbaric and hypobaric levobupivacaine for unilateral spinal anaesthesia. Sixty patients were randomly allocated into two groups to receive either 7.5 mg (1.5 ml) hyperbaric levobupivacaine 0.5% or 7.5 mg (4 ml) hypobaric levobupivacaine 0.1875% for elective arthroscopic surgery of the knee under spinal anaesthesia. The level and duration of sensory block, intensity and duration of motor block were recorded. Unilateral sensory block was observed in 27 patients (90%) in the hyperbaric group and 24 patients (80%) in the hypobaric group in the lateral position. After 15 minutes, patients were turned to supine to redistribute the spinal block toward the non-operative side, but spinal anaesthesia was still unilateral in 18 patients (60%) in the hyperbaric group and 10 patients (33%) in the hypobaric group (P = 0.038). Time to readiness for home discharge and complete recovery of sensory block were similar in both groups. In the hyperbaric group, the motor block scores were higher on the operative side during first 10 minutes than they were in the hypobaric group (P < 0.002). Motor block regression was faster in the hyperbaric group (P = 0.01). Hyperbaric and hypobaric levobupivacaine both provided satisfactory unilateral spinal anaesthesia with good haemodynamic stability for arthroscopic surgery, but with more frequent unilateral spinal anaesthesia in the hyperbaric group.

Studies in western healthcare settings suggest that preoperative anaemia is associated with poor outcomes after elective orthopaedic surgery. We investigated the prevalence of preoperative anaemia among patients with primary unilateral total knee arthroplasty (TKA) in Singapore and its association with length of hospital stay (LOS), perioperative blood transfusion and hospital readmission rates. Retrospective cohort study performed in a tertiary academic medical centre in Singapore, involving patients who underwent primary unilateral TKA between January 2013 and June 2014. Demographics, comorbidities, preoperative haemoglobin (Hb) level, LOS and 30-day readmission data were collected. Anaemia was classified according to WHO definition. Prolonged LOS was defined as more than 6 days, which corresponds to >75th centile LOS of the data. We analysed 2394 patients. The prevalence of anaemia was 23.7%. 403 patients (16.8%) had mild anaemia and 164 patients (6.8%) had moderate to severe anaemia. Overall mean LOS was 5.4±4.8 days. Based on multivariate logistic regression, preoperative anaemia significantly increased LOS (mild anaemia, adjusted OR (aOR) 1.71, p<0.001; moderate/severe anaemia, aOR 2.29, p<0.001). Similar effects were seen when preoperative anaemia was defined by Hb level below 13 g/dL, regardless of gender. Transfusion proportionately increased prolonged LOS (1 unit: aOR 2.12, p=0.006; 2 or more units: aOR 6.71, p<0.001). Repeat operation during hospital stay, previous cerebrovascular accidents, general anaesthesia and age >70 years were associated with prolonged LOS. Our 30-day related readmission rate was 1.7% (42) cases. Anaemia is common among patients undergoing elective TKA in Singapore and is independently associated with prolonged LOS and increased perioperative blood transfusion. We suggest measures to correct anaemia prior to surgery, including the use of non-gender-based Hb cut-off for establishing diagnosis. © Article author(s) (or their

Reversible dyscognition in patients with a unilateral, middle fossa arachnoid cyst revealed by using a laptop based neuropsychological test battery (CANTAB).

2010-11-01

The aim of this study was to evaluate and validate the Cambridge Neuropsychological Test Automated Battery (CANTAB) in a Norwegian group of patients undergoing surgery for middle fossa arachnoid cysts (AC). We also wanted to assess health related quality of life (HRQOL) in these patients to see if it could be improved by decompression of the AC. Adult patients (>18 years) with unilateral middle fossa AC and no previous history of neurological disease, head injury, or a psychiatric disorder were eligible for inclusion. We used four tests from CANTAB to assess the level of neuropsychological performance: paired associate learning (PAL) and delayed matching to sample (DMS) assessed temporal lobe functions, while Stockings of Cambridge (SOC) and intra-extra dimensional (IED) shift focused on frontal lobe functions. Patients with postoperative cerebral complications were reported, but excluded from neuropsychological follow-up. In addition to the CANTAB data, pre- and postoperative clinical and radiological data were collected. HRQOL was assessed using Short Form 36 (SF-36) pre- and postoperatively. We found significant improvement in the two temporal tests assessing memory, but no improvement in the two frontal tests assessing executive function. HRQOL was significantly reduced preoperatively in two of eight SF-36 domains and improved significantly in four domains postoperatively. CANTAB facilitates detection of cognitive improvements after decompression of the cyst in patients with AC in the middle fossa. The improvements were detected on the tests sensitive to temporal lobe problems only, not on the tests more sensitive to frontal lobe affection. This establishes construct validity for CANTAB for the first time in this population.

Radiographic Measurements of the Affected and Unaffected Feet in Patients with Unilateral Hallux Limitus A Case-Control Pilot Study.

Controversy exists regarding the structural and functional causes of hallux limitus, including metatarsus primus elevatus, a long first metatarsal, first-ray hypermobility, the shape of the first metatarsal head, and the presence of hallux interphalangeus. Some articles have reported on the radiographic evaluation of these measurements in feet affected by hallux limitus, but no study has directly compared the affected and unaffected feet in patients with unilateral hallux limitus. This case-control pilot study aimed to establish whether any such differences exist. Dorsoplantar and lateral weightbearing radiographs of both feet in 30 patients with unilateral hallux limitus were assessed for grade of disease, lateral intermetatarsal angle, metatarsal protrusion distance, plantar gapping at the first metatarsocuneiform joint, metatarsal head shape, and hallux abductus interphalangeus angle. Data analysis was performed using a statistical software program. Mean radiographic measurements for affected and unaffected feet demonstrated that metatarsus primus elevatus, a short first metatarsal, first-ray hypermobility, a flat metatarsal head shape, and hallux interphalangeus were prevalent in both feet. There was no statistically significant difference between feet for any of the radiographic parameters measured (Mann-Whitney U tests, independent-samples t tests, and Pearson χ(2) tests: P > .05). No significant differences exist in the presence of the structural risk factors examined between affected and unaffected feet in patients with unilateral hallux limitus. The influence of other intrinsic factors, including footedness and family history, should be investigated further.

Milanti, Ariesta; Metsälä, Eija; Hannula, Leena

Psychological distress is a common problem among patients with cancer, yet it mostly goes unreported and untreated. This study examined the association of a psycho-educational intervention with the psychological distress levels of breast cancer and cervical cancer patients undergoing chemotherapy. The design of the study was quasi-experimental, pretest-posttest design with a comparison group. One hundred patients at a cancer hospital in Jakarta, Indonesia, completed Distress Thermometer screening before and after chemotherapy. Fifty patients in the intervention group were given a psycho-educational video with positive reappraisal, education and relaxation contents, while receiving chemotherapy. Patients who received the psycho-educational intervention had significantly lower distress levels compared with those in the control group. Routine distress screening, followed by distress management and outcome assessment, is needed to improve the wellbeing of cancer patients.

We assessed medical and surgical causes of unilateral trapezius muscle (TM) palsy and/or wasting. Clinical and electrodiagnostic data were collected in 54 patients with TM impairment over 21 years. In total, 35 cases had a medical origin: neuralgic amyotrophy (NA, n = 22), idiopathic unilateral TM palsy (n = 5), regional neck radiotherapy for different conditions (n = 2), facioscapulohumeral dystrophy (FSH) (n = 4), abnormal loop of the jugular vein (n = 1), or basilar impression (n = 1). Other etiologies were neck surgery (n = 16), cervicofacial lift (n = 2), or trauma (n = 1). There were 5 main diagnostic findings in unilateral TM palsy: (1) dynamic examination of the scapula provides a new clinical sign; (2) NA is the most frequent medical cause; (3) in medical cases, partial preservation of the upper TM can offer good recovery; (4) FSH must be considered, especially in young patients; and (5) minor neck surgery can lead to severe TM palsy.

Peginesatide, a synthetic peptide-based erythropoiesis-stimulating agent (ESA), is a potential therapy for anemia in patients with advanced chronic kidney disease. We conducted two randomized, controlled, open-label studies (EMERALD 1 and EMERALD 2) involving patients undergoing hemodialysis. Cardiovascular safety was evaluated by analysis of an adjudicated composite safety end point--death from any cause, stroke, myocardial infarction, or serious adverse events of congestive heart failure, unstable angina, or arrhythmia--with the use of pooled data from the two EMERALD studies and two studies involving patients not undergoing dialysis. In the EMERALD studies, 1608 patients received peginesatide once monthly or continued to receive epoetin one to three times a week, with the doses adjusted as necessary to maintain a hemoglobin level between 10.0 and 12.0 g per deciliter for 52 weeks or more. The primary efficacy end point was the mean change from the baseline hemoglobin level to the mean level during the evaluation period; noninferiority was established if the lower limit of the two-sided 95% confidence interval was -1.0 g per deciliter or higher in the comparison of peginesatide with epoetin. The aim of evaluating the composite safety end point in the pooled cohort was to exclude a hazard ratio with peginesatide relative to the comparator ESA of more than 1.3. In an analysis involving 693 patients from EMERALD 1 and 725 from EMERALD 2, peginesatide was noninferior to epoetin in maintaining hemoglobin levels (mean between-group difference, -0.15 g per deciliter; 95% confidence interval [CI], -0.30 to -0.01 in EMERALD 1; and 0.10 g per deciliter; 95% CI, -0.05 to 0.26 in EMERALD 2). The hazard ratio for the composite safety end point was 1.06 (95% CI, 0.89 to 1.26) with peginesatide relative to the comparator ESA in the four pooled studies (2591 patients) and 0.95 (95% CI, 0.77 to 1.17) in the EMERALD studies.

Forty-two patients with cancer-related unilateral vocal fold paralysis underwent modified arytenoid adduction between February 2001 and December 2008. Of these, 37 patients were enrolled in this retrospective study (one patient died of primary disease and four were lost to follow up). Laryngostroboscopy was performed to evaluate vocal fold orientation and mobility. Pre- and post-operative assessment of subjective and objective voice, aerodynamic parameters, and quality of life were also undertaken, and aspiration was subjectively rated. Laryngostroboscopic findings indicated a significant post-operative improvement in vocal fold posterior glottal closure and vertical gap. Significant improvements in voice quality, aerodynamic parameters and quality of life were noted three months post-operatively in all patients (p < 0.01). The overall success rate for swallowing rehabilitation was 94.6 per cent (35/37). Subjective aspiration ratings decreased significantly post-operatively, compared with pre-operative values (p < 0.01). No major complication occurred in any patient, except for dyspnoea in one patient. Modified arytenoid adduction is an effective and reliable medialisation technique which can restore satisfactory voice quality, prevent aspiration and lead to a better quality of life for patients with cancer-related unilateral vocal fold paralysis.

Objectives In this preliminary prospective study, we compared unilateral and bilateral thyroarytenoid muscle injections of Botulinum toxin (Dysport) in 31 patients with adductor spasmodic dysphonia, who had undergone more than 5 consecutive Dysport injections (either unilateral or bilateral) and had completed 5 concomitant self-rated efficacy and complication scores questionnaires related to the previous injections. We also developed a Neurophysiological Scoring (NPS) system which has utility in the treatment administration. Method and materials Data were gathered prospectively on voice improvement (self-rated 6 point scale), length of response and duration of complications (breathiness, cough, dysphagia and total voice loss). Injections were performed under electromyography (EMG) guidance. NPS scale was used to describe the EMG response. Dose and unilateral/bilateral injections were determined by clinical judgment based on previous response. Time intervals between injections were patient driven. Results Low dose unilateral Dysport injection was associated with no significant difference in the patient's outcome in terms of duration of action, voice score (VS) and complication rate when compared to bilateral injections. Unilateral injections were not associated with any post treatment total voice loss unlike the bilateral injections. Conclusion Unilateral low dose Dysport injections are recommended in the treatment of adductor spasmodic dysphonia. PMID:19852852

Variability in individual response profiles to antiplatelet therapy, in particular clopidogrel, is a well-established phenomenon. Genetic variations of the cytochrome P450 (CYP) 2C19 enzyme, a key determinant in clopidogrel metabolism, have been associated with clopidogrel response profiles. Moreover, the presence of a CYP2C19 loss-of-function allele is associated with an increased risk of atherothrombotic events among clopidogrel-treated patients undergoing percutaneous coronary interventions (PCI), prompting studies evaluating the use of genetic tests to identify patients who may be potential candidates for alternative platelet P2Y 12 receptor inhibiting therapies (prasugrel or ticagrelor). Areas covered: The present manuscript provides an overview of genetic factors associated with response profiles to platelet P2Y 12 receptor inhibitors and their clinical implications, as well as the most recent developments and future considerations on the role of genetic testing in patients undergoing PCI. Expert commentary: The availability of more user-friendly genetic tests has contributed towards the development of many ongoing clinical trials and personalized medicine programs for patients undergoing PCI. Results of pilot investigations have shown promising results, which however need to be confirmed in larger-scale studies to support the routine use of genetic testing as a strategy to personalize antiplatelet therapy and improve clinical outcomes.

Because the islets of Langerhans are more prevalent in the body and tail of the pancreas, distal pancreatectomy (DP) is believed to increase the likelihood of developing new onset diabetes mellitus (NODM). To determine whether the development of postoperative diabetes was more prevalent in patients undergoing DP or Whipple procedure, 472 patients undergoing either a DP (n = 122) or Whipple (n = 350), regardless of underlying pathology, were analyzed at one month postoperatively. Insulin or oral hypoglycemic requirements were assessed and patients were stratified into preoperative diabetic status: NODM or preexisting diabetes. A retrospective chart review of the 472 patients between 1996 and 2014 showed that the total rate of NODM after Whipple procedure was 43 per cent, which was not different from patients undergoing DP (45%). The incidence of preoperative diabetes was 12 per cent in patients undergoing the Whipple procedure and 17 per cent in the DP cohort. Thus, the overall incidence of diabetes after Whipple procedure was 54 and 49 per cent in the DP group. The development of diabetes was unrelated to the type of resection performed. Age more than 65 and Caucasian ethnicity were associated with postoperative diabetes regardless of the type of resection performed.

We conducted this study to identify differences in the re-treatment rates and ancillary procedures for the two most commonly utilized stone treatment procedures in the Medicare population: ureteroscopy (URS) and shock wave lithotripsy (SWL). A retrospective claims analysis of the Medicare standard analytical file 5% sample was conducted to identify patients with a new diagnosis of urolithiasis undergoing treatment with URS or SWL from 2009-2010. Outcomes evaluated: (1) repeat stone removal procedures within 120 days post index procedure, (2) stent placement procedures on the index date, 30 days prior to and 120 days post index date, and (3) use of general anesthesia. We identified 3885 eligible patients, of which 2165 (56%) underwent SWL and 1720 (44%) underwent URS. Overall, SWL patients were 1.73 times more likely to undergo at least one repeat procedure than URS patients, and twice as likely to require multiple re-treatments compared to URS. Among those with ureteral stones, SWL patients were 2.27 times more likely to undergo repeat procedures. The difference was not statistically significant in renal stone patients. Overall, SWL patients were 1.41 times more likely than URS patients to have a stent placed prior to index procedure, and 1.33 times more likely to have a stent placed subsequent to the index procedure. The majority of URS patients (77.8%) had a stent placed at the time of index procedure. There was no significant difference in anesthetic approaches between SWL and URS. Patients undergoing SWL are significantly more likely to require re-treatments than URS patients. SWL patients are also significantly more likely to require ureteral stent placement as a separate event. SWL and URS patients have similar rates of general anesthesia.

Background Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity. Objectives Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.e. the infiltration of myenteric ganglions by inflammatory cells) in patients undergoing surgery for this condition. Methods We analyzed archival resection samples from the proximal resection margins of 165 patients undergoing left hemicolectomy (60 emergency and 105 elective surgeries) for colonic diverticulitis, by histology and immunochemistry. Results Overall, plexitis was present in almost 40% of patients. It was subdivided into an eosinophilic (48%) and a lymphocytic (52%) subtype. Plexitis was more frequent in younger patients; and it was more frequent in those undergoing emergency surgery (50%), compared to elective (28%) surgery (p = 0.007). All the severe cases of plexitis displayed the lymphocytic subtype. Conclusions In conclusion, myenteric plexitis is frequent in patients with colonic diverticular disease needing surgery, and it might be implicated in the pathogenesis of the disease. PMID:26668745

Aim: This study aimed to evaluate the benefits of Arnica montana on post-operative blood loss and seroma production in women undergoing unilateral total mastectomy by administering Arnica Montana 1000 Korsakovian dilution (1000 K). Materials and Methods: From 2012 to 2014, 53 women were randomly assigned to A. montana or placebo and were followed up for 5 days. The main end point was the reduction in blood and serum volumes collected in drainages. Secondary end points were duration of drainage, a self-evaluation of pain, and the presence of bruising or hematomas. Results: The per-protocol analysis revealed a lower mean volume of blood and serum collected in drainages with A. montana (−94.40 ml; 95% confidence interval [CI]: 22.48-211.28; P = 0.11). A regression model including treatment, volume collected in the drainage on the day of surgery, and patient weight showed a statistically significant difference in favor of A. montana (−106.28 ml; 95% CI: 9.45-203.11; P = 0.03). Volumes collected on the day of surgery and the following days were significantly lower with A. montana at days 2 (P = 0.033) and 3 (P = 0.0223). Secondary end points have not revealed significant differences. Conclusions: A. montana 1000 K could reduce post-operative blood and seroma collection in women undergoing unilateral total mastectomy. Larger studies are needed with different dilutions of A. montana to further validate these data. PMID:28163953

The prognostic implications of dyspnea and typical angina in patients referred for coronary CT angiography have not been examined. We examined features associated with incident mortality risk among individuals undergoing coronary computed tomographic angiography (CCTA) presenting with dyspnea, typical angina, and neither of these symptoms. 1147 consecutive individuals without known CAD (mean 61 years, 61.6 %men) undergoing CCTA comprised the study population 132 with dyspnea, 218 with typical angina, and 797 without dyspnea or typical angina (reference group). Mortality risk in relation to dyspnea or typical angina was evaluated with multivariable Cox proportional hazards models compared to reference. In addition, the prognosis associated with dyspnea or typical angina was assessed among age matched subgroups. Patients with dyspnea had a greater prevalence of C70 % stenosis (p\\0.001) and coronary segments with plaque (p = 0.02) compared to the other two groups. During a follow-up of 3.1 years, 52 individuals died. By multivariable Cox models, compared to patients in reference group, dyspnea patients experienced higher mortality (HR 2.0, 95 % CI 1.0–4.0, p = 0.049) while typical angina patients did not (HR 1.1, 95 % CI 0.6–2.3, p = 0.76). In the matched group, the patients with dyspnea (HR 2.2, 95 % CI 1.1–4.3, p = 0.03) still had significantly reduced survival compared to the other two groups, while those with typical angina did not (HR 1.2, 95 % CI 0.6–2.6,p = 0.62). Dyspnea is associated with increased mortality ate compared to patients with typical angina and those with neither of these symptoms among patients undergoing CCTA.

Information on the coexistence of lumbar spondylosis and its influence on overall levels of pain and function in patients with advanced knee osteoarthritis (OA) undergoing total knee arthroplasty (TKA) would be valuable for patient consultation and management. The purposes of this study were to document the prevalence and severity of coexisting lumbar spondylosis in patients with advanced knee OA undergoing TKA and to determine whether the coexisting lumbar spondylosis at the time of TKA adversely affects clinical scores in affected patients before and 2 years after TKA. Radiographic lumbar spine degeneration and lumbar spine symptoms including lower back pain, radiating pain at rest, and radiating pain with activity were assessed in 225 patients undergoing TKA. In addition, the WOMAC score and the SF-36 scores were evaluated before and 2 years after TKA. Potential associations of radiographic lumbar spine degeneration and lumbar spine symptom severities with pre- and postoperative WOMAC subscales and SF-36 scores were examined. All 225 patients had radiographic degeneration of the lumbar spine, and the large majority (89% [200 of 225]) had either moderate or severe spondylosis (72% and 17%, respectively). A total of 114 patients (51%) had at least one moderate or severe lumbar spine symptom. No association was found between radiographic severity of lumbar spine degeneration and pre- and postoperative clinical scores. In terms of lumbar spine symptoms, more severe symptoms were likely to adversely affect the preoperative WOMAC and SF-36 physical component summary (PCS) scores, but most of these adverse effects improved by 2 years after TKA with the exception of the association between severe radiating pain during activity and a poorer postoperative SF-36 PCS score (regression coefficient = -5.41, p = 0.015). Radiographic lumbar spine degeneration and lumbar spine symptoms are common among patients with advanced knee OA undergoing TKA. Severe lumbar spine symptoms

Background: Kidney transplantation is the best available treatment for patients with end-stage renal disease. Objective: To evaluate the en bloc anastomosis technique for unilateral dual kidney transplantation (DKT). Methods: From May to October 2011, 5 patients (4 women and 1 man) with mean age of 31.8 years underwent unilateral DKT with this technique in which distal end of the aorta and proximal end of inferior vena cava (IVC) were closed with running sutures. Then, proximal end of the aorta and distal end of the IVC were anastomosed to internal (or external) iliac artery and external iliac vein, respectively. Results: Post-operative course was uneventful. No vascular and urologic complications developed; all patient had acceptable serum creatinine at discharge time and up of 2–6 months of post-operation follow up. Conclusion: Unilateral DKT is a safe method for performing DKT. The proposed en bloc anastomosis can improve the outcome of the graft by reducing the cold ischemia and the operation time.

Reduction of cognitive function is a possible side effect after the use of cardiopulmonary bypass (CPB) during cardiac surgery. Since it has been proven that piracetam is cerebroprotective in patients undergoing coronary bypass surgery, we investigated the effects of piracetam on the cognitive performance of patients undergoing open heart surgery. Patients scheduled for elective open heart surgery were randomized to the piracetam or placebo group in a double-blind study. Patients received 12 g of piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on day 3, postoperatively. To assess the overall cognitive function and the degree of cognitive decline across all tests after the surgery, we combined the six test-scores by principal component analysis. A total of 88 patients with a mean age of 67 years were enrolled into the study. The mean duration of CPB was 110 minutes. Preoperative clinical parameters and overall cognitive functions were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed deterioration of cognitive function in both groups (piracetam: preoperative 0.19 ± 0.97 vs. postoperative -0.97 ± 1.38, p <0.0005 and placebo: preoperative -0.14 ± 0.98 vs. postoperative -1.35 ± 1.23, p <0.0005). Patients taking piracetam did not perform better than those taking placebo, and both groups had the same decline of overall cognitive function (p = 0.955). Piracetam had no cerebroprotective effect in patients undergoing open heart surgery. Unlike the patients who underwent coronary surgery, piracetam did not reduce the early postoperative decline of neuropsychological abilities in heart valve patients.

Schizencephaly is a rare and severe congenital brain defect. Its etiology is not unequivocal and its clinical course differs with every case. The aim of the study was to analyze correlations between clinical and radiologic features of schizencephaly in Polish patients. The study group consisted of 25 children. Epileptic seizures were observed in 60% of cases and in 32% epilepsy was drug resistant. Generalized hypotonia was found in 24%, spastic diparesis in 48%, and spastic hemiparesis in 28% of cases. Seizures were more frequent in the bilateral than unilateral schizencephaly subgroup (72% vs 29%, P = .045). There was a correlation between the presence of the bilateral type II schizencephaly and the occurrence of seizures (P = .002, r = 0.578). There is a correlation between the type of schizencephaly and the presence of seizures in Polish pediatric patients. In most of the patients, schizencephaly leads to developmental retardation and epileptic seizures.

Unilateral vocal fold paralysis is a common clinical problem which frequently causes severe dysphonia. Various treatment options exist for this condition, with the type I thyroplasty being one of the more commonly performed surgical procedures for vocal rehabilitation. The Voice-Related Quality of Life (V-RQOL) Measure is a validated outcomes instrument for voice disorders. This study measured the V-RQOL of patients with unilateral vocal fold paralysis who had undergone a type I thyroplasty and compared these scores to those of patients with untreated and uncompensated unilateral vocal fold paralysis and to normals. Treated patients had significantly higher domain and overall V-RQOL scores than untreated patients, but also scored lower than normals. These differences were true across gender and age. Patients who were more distant from surgery had lower V-RQOL scores than those who had more recently been treated. It is concluded that type I thyroplasty leads to a significantly higher V-RQOL for patients with unilateral vocal fold paralysis. This study also demonstrates further the utility of patient-oriented measures of treatment outcome.

Retrospective database analysis. To investigate incidence, comorbidities, and impact on health care resources of Clostridium difficile infection after lumbar spine surgery. C. difficile colitis is reportedly increasing in hospitalized patients and can have a negative impact on patient outcomes. No data exist on estimates of C. difficile infection rates and its consequences on patient outcomes and health care resources among patients undergoing lumbar spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Patients were included for study based on International Classification of Diseases, Ninth Revision, Clinical Modification, procedural codes for lumbar spine surgery for degenerative diagnoses. Baseline patient characteristics were determined and multivariable analyses assessed factors associated with increased incidence of C. difficile and risk of mortality. The incidence of C. difficile infection in patients undergoing lumbar spine surgery is 0.11%. At baseline, patients infected with C. difficile were significantly older (65.4 yr vs. 58.9 yr, P<0.0001) and more likely to have diabetes with chronic complications, neurological complications, congestive heart failure, pulmonary disorders, coagulopathy, and renal failure. Lumbar fusion (P=0.0001) and lumbar fusion revision (P=0.0003) were associated with increased odds of postoperative infection. Small hospital size was associated with decreased odds (odds ratio [OR], 0.5; P<0.001), whereas urban hospitals were associated with increased odds (OR, 2.14; P<0.14) of acquiring infection. Uninsured (OR, 1.62; P<0.0001) and patients with Medicaid (OR, 1.33; P<0.0001) were associated with higher odds of acquiring postoperative infection. C. difficile increased hospital length of stay by 8 days (P<0.0001), hospital charges by 2-fold (P<0.0001), and inpatient mortality to 4% from 0.11% (P<0.0001). C. difficile infection after lumbar spine surgery carries a 36.4-fold increase in mortality and costs

INTRODUCTION Gynecomastia is the benign proliferation of the glandular tissue in the male breast. This condition is thought to be caused by the imbalance between estrogen action relative to androgen action at the breast tissue level. Bilateral gynecomastia is frequently found in the neonatal period, early in puberty, and with increasing age. Prepubertal unilateral gynecomastia in the absence of endocrine abnormalities is extremely rare, with only a few cases in literature. PRESENTATION OF CASE We present an otherwise healthy boy of 12 years old with unilateral breast masses. No abnormalities were found on ultrasonography and on all endocrine parameters. Treatment consisted in a new “modified” Webster technique. DISCUSSION The results confirmed validity of this technique in terms of esthetic and functional results, and patient satisfaction. Atypical presentations of gynecomastia are often not recognized. The main pathophysiology of gynecomastia is alteration in the balance between the stimulatory effect of estrogen and the inhibitory effects of androgens on the development of the breast. If there is no causal treatment, surgical resection is the therapy of first choice. CONCLUSION The exact mechanism of unilateral gynecomastia formation in our case is unclear. The evaluation of unilateral gynecomastia can therefore be complex. In conclusion, the surgical treatment of unilateral gynecomastia requires an individual approach, based on an appropriate diagnostic algorithm. PMID:25437663

Previous studies have indicated that music decreases intraoperative sedative requirements in patients undergoing surgical procedures under regional anesthesia. In this study we sought to determine whether this decrease in sedative requirements results from music or from eliminating operating room (OR) noise. A secondary aim of the study was to examine the relationship of response to intraoperative music and participants' culture (i.e., American versus Lebanese). Eighty adults (36 American and 54 Lebanese) undergoing urological procedures with spinal anesthesia and patient-controlled IV propofol sedation were randomly assigned to intraoperative music, white noise, or OR noise. We found that, controlling for ambient OR noise, intraoperative music decreases propofol requirements (0.004 +/- 0.002 mg . kg(-1) . min(-1) versus 0.014 +/- 0.004 mg . kg(-1) . min(-1) versus 0.012 +/- 0.002 mg . kg(-1) . min(-1); P = 0.026). We also found that, regardless of group assignment, Lebanese patients used less propofol as compared with American patients (0.005 +/- 0.001 mg . kg(-1) . min(-1) versus 0.017 +/- 0.003 mg . kg(-1) . min(-1); P = 0.001) and that, in both sites, patients in the music group required less propofol (P < 0.05). We conclude that when controlling for ambient OR noise, intraoperative music decreases propofol requirements of both Lebanese and American patients who undergo urological surgery under spinal anesthesia.

Clinical predictors of perioperative mortality in geriatric patients undergoing emergent general surgery have not been well described. The purpose of this study was to determine the incidence of postoperative morbidity and mortality in geriatric patients and factors associated with mortality. A retrospective review of patients 65 years of age or older undergoing emergent general surgery at a public teaching hospital was performed over a 7-year period. Data collected included demographics, comorbidities, laboratory studies, perioperative morbidities, and mortality. Descriptive statistics and predictors of morbidity and mortality are described. The mean age was 74 years. Indications for surgery included small bowel obstruction (24%), diverticulitis (20%), perforated viscous (16%), and large bowel obstruction (9%). The overall complication rate was 41 per cent with six cardiac complications (14%) and seven perioperative (16%) deaths. Mean admission serum creatinine was significantly higher in patients who died (3.6 vs 1.5 mg/dL, P = 0.004). Mortality for patients with an admission serum creatinine greater than 2.0 mg/dL was 42 per cent (5 of 12) compared with 3 per cent (2 of 32) for those 2.0 mg/dL or less (OR, 10.7; CI, 1.7 to 67; P = 0.01). Morbidity and mortality in geriatric patients undergoing emergency surgery remains high with the most significant predictor of mortality being the presence of renal insufficiency on admission.

Patients undergoing hemodialysis have a higher rate of hepatitis C virus infection than the general population, and due to various factors including hemodialysis and immunosuppression, it is difficult to make a diagnosis. The appearance of direct-acting antiviral agents greatly promotes the treatment of hepatitis C, but there are still no adequate data on their effect and safety in patients undergoing hemodialysis. This article discusses the prevalence, diagnosis, and treatment of hepatitis C in patients undergoing hemodialysis.

Due to lack of awareness and non-availability of proper medical facilities in Pakistan, patients with kidney problems tend to seek urological consultation very late when their kidney has already knocked-out. The aim of the study was to find the various presenting complaints of patients having unilateral loss of kidney function and their aetiologies. The study also targeted the patient's awareness regarding their disease. This descriptive case-series of 103 consecutive patients who were diagnosed as having less than 20% of function on DTPA Renal Scan were evaluated. The aetiology of the non-functioning kidney (NFK) was made on either imaging findings or during the exploration, and/or on histopathology if necessary. The results were analysed using SPSS 16.0. Results: The aetiology of the unilateral renal failure included those that were secondary to nephro-pelvic stones in 39.8% and ureteric stones in 14.6%. Of the other aetiologies culminating in a unilateral NFK, 7.8% of the patients had chronic pyelonephritis, 20.4% had PUJO and 5.8% were Genito-urinary Tuberculosis; 3.9% had VUR and were found incidentally, 3.9% developed non-functioning kidney iatrogenically. About 39.8% of the patients knew about their primary disease causing destruction of renal function since long. The remaining 60.2% were unaware that they had developed NFK already when they presented. Proper education through awareness program both for the public and general practitioners can detect early threats to the kidney and hence decrease the loss of a kidney. This will also decrease the number of nephrectomies carried out for the benign condition.

OBJECT Patients with occipitocervical (OC) instability from congenital vertebral anomalies (CVAs) of the craniocervical junction (CCJ) often have bony abnormalities that make instrumentation placement difficult. Within this patient population, some bilateral instrumentation constructs either fail or are not feasible, and a unilateral construct must be used. The authors describe the surgical management and outcomes of this disorder in patients in whom unilateral fixation constructs were used to treat OC instability. METHODS From a database of OC fusion procedures, the authors identified patients who underwent unilateral fixation for the management of OC instability. Patient characteristics, surgical details, and radiographic outcomes were reviewed. In each patient, CT scans were performed at least 4 months after surgery to evaluate for fusion. RESULTS Eight patients with CVAs of the CCJ underwent unilateral fixation for the treatment of OC instability. For 4 patients, the procedure occurred after a bilateral OC construct failed or infection forced hardware removal. For the remainder, it was the primary procedure. Two patients required reoperation for hardware revision and 1 developed nonunion requiring revision of the bone graft. Ultimately, 7 patients demonstrated osseous fusion on CT scans and 1 had a stable fibrous union. CONCLUSIONS These findings demonstrate that a unilateral OC fixation is effective for the treatment of OC instability in children with CVAs of the CCJ in whom bilateral screw placement fails or is not feasible.

Methicillin-resistant Staphylococcus aureus is a leading cause of death in patients undergoing hemodialysis. However, controversy exists about the optimal dose of vancomycin that will yield the recommended pre-hemodialysis serum concentration of 15-20 mg/L. To develop a data-driven model to optimize the accuracy of maintenance dosing of vancomycin for patients undergoing hemodialysis. A prospective observational cohort study was performed with 164 observations obtained from a convenience sample of 63 patients undergoing hemodialysis. All vancomycin doses were given on the floor after completion of a hemodialysis session. Multivariate linear generalized estimating equation analysis was used to examine independent predictors of pre-hemodialysis serum vancomycin concentration. Pre-hemodialysis serum vancomycin concentration was independently associated with maintenance dose ( B = 0.658, p < 0.001), baseline pre-hemodialysis serum concentration of the drug ( B = 0.492, p < 0.001), and interdialytic interval ( B = -2.133, p < 0.001). According to the best of 4 models that were developed, the maintenance dose of vancomycin required to achieve a pre-hemodialysis serum concentration of 15-20 mg/L, if the baseline serum concentration of the drug was also 15-20 mg/L, was 5.9 mg/kg with interdialytic interval of 48 h and 7.1 mg/kg with interdialytic interval of 72 h. However, if the baseline pre-hemodialysis serum concentration was 10-14.99 mg/L, the required dose increased to 9.2 mg/kg with an interdialytic interval of 48 h and 10.0 mg/kg with an interdialytic interval of 72 h. The maintenance dose of vancomycin varied according to baseline pre-hemodialysis serum concentration of the drug and interdialytic interval. The current practice of targeting a pre-hemodialysis concentration of 15-20 mg/L may be difficult to achieve for the majority of patients undergoing hemodialysis.

Purpose: To assess, through a retrospective review, clinical outcomes of patients with squamous cell carcinoma of the tonsil treated at the M. D. Anderson Cancer Center with unilateral radiotherapy techniques that irradiate the involved tonsil region and ipsilateral neck only. Methods and Materials: Of 901 patients with newly diagnosed squamous cell carcinoma of the tonsil treated with radiotherapy at our institution, we identified 102 that were treated using unilateral radiotherapy techniques. All patients had their primary site of disease restricted to the tonsillar fossa or anterior pillar, with <1 cm involvement of the soft palate. Patients had TX (n =more » 17 patients), T1 (n = 52), or T2 (n = 33) disease, with Nx (n = 3), N0 (n = 33), N1 (n = 23), N2a (n = 21), or N2b (n = 22) neck disease. Results: Sixty-one patients (60%) underwent diagnostic tonsillectomy before radiotherapy. Twenty-seven patients (26%) underwent excision of a cervical lymph node or neck dissection before radiotherapy. Median follow-up for surviving patients was 38 months. Locoregional control at the primary site and ipsilateral neck was 100%. Two patients experienced contralateral nodal recurrence (2%). The 5-year overall survival and disease-free survival rates were 95% and 96%, respectively. The 5-year freedom from contralateral nodal recurrence rate was 96%. Nine patients required feeding tubes during therapy. Of the 2 patients with contralateral recurrence, 1 experienced an isolated neck recurrence and was salvaged with contralateral neck dissection only and remains alive and free of disease. The other patient presented with a contralateral base of tongue tumor and involved cervical lymph node, which may have represented a second primary tumor, and died of disease. Conclusions: Unilateral radiotherapy for patients with TX-T2, N0-N2b primary tonsil carcinoma results in high rates of disease control, with low rates of contralateral nodal failure and a low incidence of acute toxicity

Objective: to evaluate the self-esteem of cancer patients undergoing chemotherapy. Method: descriptive analytical cross-sectional study with a quantitative approach. Around 156 patients that attended an oncology unit of a mid-sized hospital participated in the study. Results: we found a higher frequency of patients with high self-esteem, but some of them showed average or low self-esteem. The scale showed a Cronbach's alpha value of 0.746, by considering its acceptable internal consistency for the evaluated items. No independent variables showed significant associations with self-esteem. Conclusion: the cancer patients evaluated have presented high self-esteem; thus, it becomes crucial for nursing to plan the assistance of patients undergoing chemotherapy treatments, which enables actions and strategies that meet their physical and psychosocial conditions, aiming to maintain and rehabilitate these people's emotional aspects.

The authors determined the pharmacokinetics of fentanyl 100 micrograms X kg-1 iv in patients undergoing elective abdominal aortic surgery. The mean (+/- SD) age of the ten patients was 67.2 +/- 8.7 yr; their mean weight was 78.5 +/- 13.7 kg. Seven patients had aortic aneurysm repair, and the other three patients had aortobifemoral grafts. Serum fentanyl concentrations were determined from samples drawn at increasing intervals over a 24-h period. A three-compartment pharmacokinetic model was fit to the concentration versus time data. Total drug clearance was 9.8 +/- 1.8 ml X min-1 X kg-1. The volume of distribution at steady-state (Vdss) was 5.4 +/- 1.9 X 1 kg-1. Elimination half-time was 8.7 +/- 2.5 h. There were no significant correlations between these pharmacokinetic parameters and patient's age, duration of aortic cross-clamping, duration of surgery, intraoperative blood loss, or volume of iv fluids given intraoperatively. In healthy volunteers or patients undergoing general surgery, other investigators report mean elimination half-times for fentanyl ranging from 1.7 to 4.4 h. The prolonged elimination half-time in patients having abdominal aortic surgery has important clinical implications. In particular, recovery from large doses will take much longer than would have been anticipated from previously published fentanyl pharmacokinetic data.

Objective Unilateral hearing loss has been shown to have negative consequences for speech and language development in children. The objective of this study was to systematically review the current literature to quantify the impact of unilateral hearing loss on children, with the use of objective measures of speech and language. Data Sources PubMed, EMBASE, Medline, CINAHL, and Cochrane Library were searched from inception to March 2015. Manual searches of references were also completed. Review Methods All studies that described speech and language outcomes for children with unilateral hearing loss were included. Outcome measures included results from any test of speech and language that evaluated or had age-standardized norms. Due to heterogeneity of the data, quantitative analysis could not be completed. Qualitative analysis was performed on the included studies. Two independent evaluators reviewed each abstract and article. Results A total of 429 studies were identified; 13 met inclusion criteria and were reviewed. Overall, 7 studies showed poorer scores on various speech and language tests, with effects more pronounced for children with severe to profound hearing loss. Four studies did not demonstrate any difference in testing results between patients with unilateral hearing loss and those with normal hearing. Two studies that evaluated effects on speech and language longitudinally showed initial speech problems, with improvement in scores over time. Conclusions There are inconsistent data regarding effects of unilateral hearing loss on speech and language outcomes for children. The majority of recent studies suggest poorer speech and language testing results, especially for patients with severe to profound unilateral hearing loss.

This study was an exploratory repeated measures design comparing patients undergoing two magnitudes of surgery in the lumbar spine: lumbar herniated disc repair and posterior lumbar fusion. The present study evaluated and compared the effect of perceived pain, perceived stress, anxiety, and mood on natural killer cell activity (NKCA) and IL-6 production among adult patients undergoing lumbar surgery. Presurgical stress and anxiety can lead to detrimental patient outcomes after surgery, such as increased infection rates. It has been hypothesized that such outcomes are due to stress-immune alterations, which may be further exacerbated by the extent of surgery. However, psychologic stress, anxiety, and mood have not been previously characterized in patients undergoing spinal surgery. Pain, stress, anxiety, and mood were measured using self-report instruments at T1 (1 week before surgery), T2 (the day of surgery), T3 (the day after surgery), and T4 (6 weeks after surgery). Blood (30 mL) was collected for immune assessments at each time point. Pain, stress, anxiety, and mood state were elevated at baseline in both surgical groups and were associated with significant reduction in NKCA compared with the nonsurgical control group. A further decrease in NKCA was observed 24 hours after surgery in both surgical groups with a significant rise in stimulated IL-6 production, regardless of the magnitude of surgery. In the recovery period, NKCA increased to or above baseline values, which correlated with decreased levels of reported pain, perceived stress, anxiety, and mood state. This study demonstrated that patients undergoing elective spinal surgery are highly stressed and anxious, regardless of the magnitude of surgery and that such psychologic factors may mediate a reduction in NKCA.

Purpose: Providing data on the late diagnosis and surgical treatment of patients who underwent surgery for total unilateral congenital cataract. Methods: Systematic retrospective review of the medical record of all patients between 0 and 16 years old with total unilateral congenital cataract who underwent surgery at Fundación Vision between January 2010 and July 2012. Results: Medical records of 37 patients (51 % females) were studied, age was 7.4 (± 4.9) years (average ± SD) and 62% lived on Departamento Central (the most populated region from Paraguay). A total of 97.3% patients underwent late surgical treatment and 86.5% received a late diagnosis. The average time elapsed between the diagnosis and the surgical treatment was one month, and 62.2% of the patients underwent surgery within six months from the diagnosis. Conclusion: This study evidences that most of the patients in our series had a late treatment as a result of a late diagnosis. Based on these results we recommend establishing strategies to improve the early detection and surgical treatment of the newborns.

To determine if cropping facial images affects nasolabial aesthetics assessments in unilateral cleft lip patients and to evaluate the effect of facial attractiveness on nasolabial evaluation. Two cleft surgeons and one cleft orthodontist assessed standardized frontal photographs 4 times; nasolabial aesthetics were rated on cropped and full-face images using the Cleft Aesthetic Rating Scale, and total facial attractiveness was rated on full-face images with and without the nasolabial area blurred using a 5-point Likert scale. Cleft Palate Craniofacial Unit of a University Medical Center. Inclusion criteria: nonsyndromic unilateral cleft lip and an available frontal view photograph around 10 years of age. a history of facial trauma and an incomplete cleft. Eighty-one photographs were available for assessment. Differences in mean CARS scores between cropped versus full-face photographs and attractive versus unattractive rated patients were evaluated by paired t test. Nasolabial aesthetics are scored more negatively on full-face photographs compared to cropped photographs, regardless of facial attractiveness. (Mean CARS score, nose: cropped = 2.8, full-face = 3.0, P < .001; lip: cropped = 2.4, full-face = 2.7, P < .001; nose and lip: cropped = 2.6, full-face = 2.8, P < .001). Aesthetic outcomes of the nasolabial area are assessed significantly more positively when using cropped images compared to full-face images. For this reason, cropping images, revealing the nasolabial area only, is recommended for aesthetical assessments.

The prognostic effects of poor nutritional status and cardiac cachexia on coronary artery disease (CAD) are not clearly understood. A well-accepted nutritional status parameter, the prognostic nutritional index (PNI), which was first demonstrated to be valuable in patients with cancer and those undergoing gastrointestinal surgery, was introduced to patients requiring coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the prognostic value of PNI in patients with CAD undergoing CABG. We evaluated the in-hospital and long-term (3-y) prognostic effect of PNI on 644 patients with CAD undergoing CABG. Baseline characteristics and outcomes were compared among the patients by PNI and categorized accordingly: Q1, Q2, Q3, and Q4. Patients with lower PNI had significantly higher in-hospital and long-term mortality. Patients with lower PNI levels (Q1) had higher in-hospital mortality and had 12 times higher mortality rates than those with higher PNI levels (Q4). The higher PNI group had the lower rates and was used as the reference. Long-term mortality was higher in patients with lower PNI (Q1)-4.9 times higher than in the higher PNI group (Q4). In-hospital and long-term mortality rates were similar in the non-lower PNI groups (Q2-4). The present study demonstrated that PNI, calculated based on serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients undergoing CABG.

The aim of this study is to present a case of successful relief of bilateral occipital neuralgia (ON) using unilateral occipital nerve stimulation (ONS) and to discuss the possible underlying mechanisms. We present the case of a 59-year-old female patient with severe bilateral ON treated with unilateral ONS. We systematically reviewed previous studies of ONS for ON, discussing the possible mechanisms of ONS in the relief of ON. The patient reported complete pain relief after consistent unilateral ONS during the follow-up period. The underlying mechanisms may be linked to the relationship between pain and several brain regions, including the pons, midbrain, and periaqueductal gray. ONS is an effective and safe option for treating ON. Future studies will be required to clarify the mechanisms by which unilateral occipital stimulation provided relief for bilateral neuralgia in this case.

Comparison of topography and corneal higher order aberrations (HOA) data of fellow normal eyes of unilateral keratoconus patients with keratoconus eyes and control group. The records of 196 patients with keratoconus were reviewed. Twenty patients were identified as unilateral keratoconus. The best corrected visual acuity (BCVA), topography and aberration data of the unilateral keratoconus patients' normal eyes were compared with their contralateral keratoconus eyes and with control group eyes. For statistical analysis, flat and steep keratometry values, average corneal power, cylindrical power, surface regularity index (SRI), surface asymmetry index (SAI), inferior-superior ratio (I-S), keratoconus prediction index, and elevation-depression power (EDP) and diameter (EDD) topography indices were selected. Mean age of the unilateral keratoconus patients was 26.05±4.73 years and that of the control group was 23.6±8.53 years (p>0.05). There was no statistical difference in BCVA between normal and control eyes (p=0.108), whereas BCVA values were significantly lower in eyes with keratoconus (p=0.001). Comparison of quantitative topographic indices between the groups showed that all indices except the I-S ratio were significantly higher in the normal group than in the control group (p<0.05). The most obvious differences were in the SRI, SAI, EDP, and EDD values. All topographic indices were higher in the keratoconus eyes compared to the normal fellow eyes. There was no difference between normal eyes and the control group in terms of spherical aberration, while coma, trefoil, irregular astigmatism, and total HOA values were higher in the normal eyes of unilateral keratoconus patients (p<0.05). All HOA values were higher in keratoconus eyes than in the control group. According to our study, SRI, SAI, EDP, EDD values, and HOA other than spherical aberration were higher in the clinically and topographically normal fellow eyes of unilateral keratoconus patients when compared

Cardiac surgery is a highly complex procedure which generates worsening of lung function and decreased inspiratory muscle strength. The inspiratory muscle training becomes effective for muscle strengthening and can improve functional capacity. To investigate the effect of inspiratory muscle training on functional capacity submaximal and inspiratory muscle strength in patients undergoing cardiac surgery. This is a clinical randomized controlled trial with patients undergoing cardiac surgery at Instituto Nobre de Cardiologia. Patients were divided into two groups: control group and training. Preoperatively, were assessed the maximum inspiratory pressure and the distance covered in a 6-minute walk test. From the third postoperative day, the control group was managed according to the routine of the unit while the training group underwent daily protocol of respiratory muscle training until the day of discharge. 50 patients, 27 (54%) males were included, with a mean age of 56.7±13.9 years. After the analysis, the training group had significant increase in maximum inspiratory pressure (69.5±14.9 vs. 83.1±19.1 cmH2O, P=0.0073) and 6-minute walk test (422.4±102.8 vs. 502.4±112.8 m, P=0.0031). We conclude that inspiratory muscle training was effective in improving functional capacity submaximal and inspiratory muscle strength in this sample of patients undergoing cardiac surgery.

Glycogen storage diseases are rare genetic disorders of glycogen synthesis, degradation, or metabolism regulation. When these patients are subjected to anesthesia, perioperative complications can develop, including hypoglycemia, rhabdomyolysis, myoglobinuria, acute renal failure, and postoperative fatigue. The objective of this study was to describe the perioperative course of a cohort of patients with glycogen storage diseases. This is a retrospective review of patients with glycogen storage diseases undergoing anesthetic care at our institution from January 1, 1990, through June 30, 2015 to assess perioperative management and outcomes. We identified 30 patients with a glycogen storage disease who underwent 41 procedures under anesthesia management. Intraoperative lactic acidosis developed during 4 major surgeries (3 liver transplants, 1 myectomy), and in all cases resolved within 24 postoperative hours. Lactated Ringer solution was used frequently. Preoperative and intraoperative hypoglycemia was noted in some patients with glycogen storage disease type I, all of which responded to administration of dextrose-containing solutions. No serious postoperative complications occurred. Patients with glycogen storage disease, despite substantial comorbid conditions, tolerates the anesthetic management without major complications. Several patients who experienced self-limited metabolic acidosis were undergoing major surgical procedures, during which acidosis could be anticipated. Close monitoring and management of blood glucose levels of patients with glycogen storage disease type I is prudent.

To investigate the prevalence of mandibular asymmetry (MA) within the symptomatic unilateral anterior disc displacement (ADD) patients, and analyze the influence TMJ factors of the MA severity. Patients aged under 20 years old with symptomatic unilateral ADD and asymptomatic volunteers with normal disc-condyle relationship diagnosed by magnetic resonance imaging (MRI) were included in this study. Posteroanterior cephalometric radiographs were taken to measure MA. Condylar height, disc length and disc displacement were measured by MRI. The prevalence and severity of MA were compared between the ADD and the control groups. The correlation between the severity of MA with the amount of condylar height shortage, disc deformity and distance of disc displacement were also evaluated within the ADD group. There were 165 cases in the unilateral ADD group, and 156 cases in the control group. One hundred and nineteen cases had MA which accounted 72.12% (119/165) in the ADD group; while in the control group, only 25.64% (40/156) exhibited MA. The mean horizontal menton deviation and condylar height shortage in the unilateral ADD group were significantly larger than that in the control group (5.62 mm vs. 4.19 mm; 3.14 mm vs. 1.32 mm, p < 0.01). The severity of MA was significantly correlated with the amount of disc displacement, disc deformity and condylar height shortage (correlation coefficient: 0.80, 0.70, and 0.82). MA is much more common and severe in young unilateral ADD patients. The severity of MA is correlated with the height of condyle and the status of the disc.

Dorsal pancreatic agenesis is a very rare congenital anomaly. Unilateral renal agenesis, on the other hand, is a relatively common congenital anomaly, although its etiology is not fully understood. Renal and pancreatic embryologic development appears to be nonrelated. We report a case of a 34-year-old man who was referred to our hospital for evaluation of cholestasis and microalbuminuria. Ultrasound and magnetic resonance imaging examinations showed empty right renal fossa and absence of the pancreatic neck, body, and tail. Our case report is the second case of a dorsal pancreatic agenesis and unilateral renal agenesis in a young male patient.

We describe the treatment outcomes of patients with bilateral Warthin tumors in the parotid gland according to surgical methods. The medical records of ten patients with bilateral Warthin tumors in the parotid gland who underwent surgery between 2004 and 2011 were retrospectively reviewed. Ten patients were included in the study and 13 parotidectomies were performed. Patients with bilateral Warthin tumors in the parotid gland were divided into three groups according to the surgical methods used to treat these individuals. In group 1, the patients were closely observed without undergoing contralateral parotidectomy after unilateral parotidectomy. In group 2, the patients underwent concurrent bilateral parotidectomies. In group 3, the patient underwent contralateral parotidectomy 2 months after unilateral parotidectomy was performed. The overall rate of transient facial nerve dysfunction was 31%. Our findings suggest that concurrent superficial parotidectomy may be an appropriate method for treating bilateral Warthin tumors in the parotid gland, at least for desired patients. The symptoms of this type of tumor and physical examination findings are frequently non-specific and present in the unilateral parotid gland. Therefore, a high degree of discernment is needed and imaging techniques are essential for the determining the correct pre-operative diagnosis.

Postural stability in humans is largely maintained by vestibular, visual, and somatosensory inputs to the central nervous system. Recent clinical advances in the assessment of otolith function (e.g., cervical and ocular vestibular evoked myogenic potentials [cVEMPs and oVEMPs], subjective visual vertical [SVV] during eccentric rotation) have enabled investigators to identify patients with unilateral otolith impairments. This research has suggested that patients with unilateral otolith impairments perform worse than normal healthy controls on measures of postural stability. It is not yet known if patients with unilateral impairments of the saccule and/or inferior vestibular nerve (i.e., unilaterally abnormal cVEMP) perform differently on measures of postural stability than patients with unilateral impairments of the horizontal SCC (semicircular canal) and/or superior vestibular nerve (i.e., unilateral caloric weakness). Further, it is not known what relationship exists, if any, between otolith system impairment and self-report dizziness handicap. The purpose of this investigation was to determine the extent to which saccular impairments (defined by a unilaterally absent cVEMP) and impairments of the horizontal semicircular canal (as measured by the results of caloric testing) affect vestibulospinal function as measured through the Sensory Organization Test (SOT) of the computerized dynamic posturography (CDP). A secondary objective of this investigation was to measure the effects, if any, that saccular impairment has on a modality-specific measure of health-related quality of life. A retrospective cohort study. Subjects were assigned to one of four groups based on results from balance function testing: Group 1 (abnormal cVEMP response only), Group 2 (abnormal caloric response only), Group 3 (abnormal cVEMP and abnormal caloric response), and Group 4 (normal control group). Subjects were 92 adult patients: 62 were seen for balance function testing due to complaints

Cardiac manifestations of Marfan syndrome include aortic root dilation and mitral valve prolapse (MVP). Only scant data exist describing MVP in patients with Marfan syndrome undergoing aortic root replacement. We retrospectively analyzed data from 166 MFS patients with MVP who were enrolled in a prospective multicenter registry of patients who underwent aortic root aneurysm repair. Of these 166 patients, 9% had mitral regurgitation (MR) grade >2, and 10% had MR grade 2. The severity of MVP and MR was evaluated by echocardiography preoperatively and ≤ 3 years postoperatively. Forty-one patients (25%) underwent composite graft aortic valve replacement, and 125 patients (75%) underwent aortic valve-sparing procedures; both groups had similar prevalences of MR grade >2 (P=0.7). Thirty-three patients (20%) underwent concomitant mitral valve (MV) intervention (repair, n=29; replacement, n=4), including all 15 patients with MR grade >2. Only 1 patient required MV reintervention during follow-up (mean clinical follow-up, 31 ± 10 months). Echocardiography performed 21 ± 13 months postoperatively revealed MR >2 in only 3 patients (2%). One early death and 2 late deaths occurred. Although the majority of patients with Marfan syndrome who undergo elective aortic root replacement have MVP, only 20% have concomitant MV procedures. These concomitant procedures do not seem to increase operative risk. In patients with MR grade ≤ 2 who do not undergo a concomitant MV procedure, the short-term incidence of progressive MR is low; however, more follow-up is needed to determine whether patients with MVP and MR grade ≤ 2 would benefit from prophylactic MV intervention.

The aim of the study was to determine whether depressed aged inpatients treated with brief pulse unilateral electroconvulsive therapy (ECT) differed from those treated with bilateral (bitemporal or bifrontal) ECT with respect to numbers of treatments, length of hospital admission, changes in scores on depression and cognitive scales, and serious adverse effects. An audit of routinely collected data regarding 221 acute ECT courses in 7 public aged psychiatry services in Victoria, Australia. Patients given unilateral, bifrontal, and bitemporal treatments were similar with respect to personal, clinical, and treatment characteristics. Most treatments were administered in line with local clinical guidelines and were rated as effective. Psychiatrists preferred unilateral ECT in the first instance with stimulus dosing based on patients' seizure thresholds. Approximately a quarter of unilateral courses were switched later to bitemporal placement, most probably because of insufficient progress. Bilateral treatments were associated with a larger number of treatments, less improvement in scores on mood and cognitive scales, and more refusals to continue treatment than unilateral-only ECT. Brief pulse unilateral ECT proved more effective than bitemporal and bifrontal ECT for most aged patients, especially when coupled with stimulus dosing based on seizure threshold.

To identify factors of oral health important for the final outcome, after secondary alveolar bone grafting in patients born with unilateral cleft lip and palate and compare occlusal radiographs with cone beam computed tomography (CBCT) in assessment of alveolar bone height. Observational follow-up study. Cleft Lip and Palate Team, Craniofacial Center, Uppsala University Hospital, Sweden. 40 nonsyndromic, Caucasian patients with unilateral complete cleft lip and palate. Clinical examination, CBCT, and occlusal radiographs. Alveolar bone height was evaluated according to Bergland index at a 20-year follow-up. The alveolar bone height in the cleft area was significantly reduced compared to a previously reported 10-year follow-up in the same cohort by total ( P = .045) and by subgroup with dental restoration ( P = .0078). This was positively correlated with the gingival bleeding index (GBI) ( r = 0.51, P = .0008) and presence of dental restorations in the cleft area ( r = 0.45, P = .0170). There was no difference in the Bergland index generated from scoring the alveolar bone height on occlusal radiographs as with the equivalent index on CBCT. Patients rehabilitated with complex dental restoration seems to be at higher risk for progression of bone loss in the cleft area. Supportive periodontal therapy should be implemented after complex dental restorations in cleft patients. Conventional occlusal radiographs provide an adequate image for evaluating postoperative bone height in clinical follow-up.

[Hereditary heterozygous factor VII deficiency in patients undergoing surgery : Clinical relevance].

A hereditary deficiency in coagulation factor VII (FVII) may affect the international normalized ratio (INR) value. However, FVII deficiency is occasionally associated with a tendency to bleed spontaneously. We hypothesized that perioperative substitution with coagulation factor concentrates might not be indicated in most patients. In this retrospective data analysis, we included all patients with hereditary heterozygous FVII deficiency who underwent surgical procedures at the University Hospital Basel between December 2010 and November 2015. In addition, by searching the literature, we identified publications reporting patients with FVII deficiency undergoing surgical procedures without perioperative substitution. We identified 22 patients undergoing 46 surgical procedures, resulting in a prevalence of 1:1500-2000. Coagulation factor concentrates were administered during the perioperative period in 15 procedures (33 %), whereas in the other 31 procedures (66 %), FVII deficiency was not substituted. No postoperative bleeding or thromboembolic events were reported. In addition, we found no differences in pre- and postoperative hemoglobin and coagulation parameters, with the exception of an improved postoperative INR value in the substituted group. In the literature review, we identified five publications, including 125 patients with FVII deficiency, undergoing 213 surgical procedures with no perioperative substitution. Preoperative substitution using coagulation factor concentrates does not seem to be mandatory in patients with an FVII level ≥15 %. For decision-making on preoperative substitution, patient history of an increased tendency to bleed may be more important than the FVII level or increased INR value.

Both transversus abdominis plane (TAP) block and combined ilioinguinal-iliohypogastric (IIN/IHN) blocks are used routinely under ultrasound (USG) guidance for postoperative pain relief in patients undergoing inguinal hernia surgery. This study compares USG guided TAP Vs IIN/IHN block for post-operative analgesic efficacy in adults undergoing inguinal hernia surgery. Sixty adults aged 18 to 60 with American Society of Anesthesiologsts' grade I or II were included. After general anaesthesia, patients in Group I received USG guided unilateral TAP block using 0.75% ropivacaine 3 mg/kg (maximum 25 mL) and those in Group II received IIN/IHN block using 10 mL 0.75% ropivacaine. Postoperative rescue analgesia was with tramadol (intravenous) IV ± diclofenac IV in the first 4 h followed by oral diclofenac subsequently. Total analgesic consumption in the first 24 h was the primary objective, intraoperative haemodynamics, number of attempts and time required for performing the block as well as the postoperative pain scores were also evaluated. Time to first analgesic request was 319.8 ± 115.2 min in Group I and 408 ± 116.4 min in Group II ( P = 0.005). Seven patients (23.33%) in Group I and two (6.67%) in Group II required tramadol in first four hours. No patient in either groups received diclofenac IV. The average dose of tablet diclofenac was 200 ± 35.96 mg in Group I and 172.5 ± 34.96 mg in Group II ( P = 0. 004). USG guided IIN/IHN block reduces the postoperative analgesic requirement compared to USG guided TAP block.

Adrenal vein sampling (AVS) is intended to confirm unilateral forms of primary aldosteronism, which are amenable to surgical cure. Excessively strict AVS criteria to define lateralization may result in many patients incorrectly categorized as bilateral primary aldosteronism and opportunity for surgical cure missed. Retrospective review of an AVS-primary aldosteronism database in which surgical cases are verified by standardized outcomes. Having used 'less strict' AVS criteria for lateralization, we examined the distribution of AVS lateralization indices in our confirmed unilateral primary aldosteronism cases both with and without cosyntropin stimulation. The proportion of proven unilateral cases that would have been missed with stricter AVS interpretation criteria was calculated. Particular focus was given to the proportion of missed cases according to use of international guidelines. False-positive lateralization with 'less strict' interpretation was also calculated. Of 80 surgical primary aldosteronism cases, 10-23% would have been missed with AVS lateralization indices of 3 : 1 to 5 : 1, with or without cosyntropin. If strict selectivity indices (for confirmation of catheterization) were combined with strict lateralization indices, up to 70% of unilateral primary aldosteronism cases could have been missed. Use of Endocrine Society AVS guidelines would have missed 21-43% of proven unilateral cases. 'Less strict' AVS interpretation yielded one case (1.2%) of false lateralization. Excessively strict AVS interpretation criteria will result in a high rate of missed unilateral primary aldosteronism with subsequent loss of opportunity for intervention. Use of more lenient lateralization criteria will improve the detection rate of unilateral primary aldosteronism with very low false-positive rate.

Blood loss in total knee arthroplasty (TKA) is an area of significant concern as it has an effect on patient morbidity and hospital stay. Among many different modalities to reduce blood loss, the use of Tranexamic acid has become a standard procedure nowadays. The aim of our study was to determine if Tranexamic acid alone decreases blood loss as an independent variable irrespective of other blood loss preserving measures. This prospective non-randomized study included patients undergoing unilateral TKA by conventional method (Group 1) and computer-assisted TKA (Group 2). All the patients in both groups received Tranexamic acid in a dose of 10 mg/kg body weight prior to inflation of tourniquet. Blood loss in both the groups was calculated using Nadler's formula, and haemoglobin (Hb) level was calculated on day one and day three after surgery. The mean drop of Hb in Group 1 was 1.608 and 1.56 g/dl in Group 2 which was statistically significant (p < 0.001); however, none of the patients in either of the groups actually required any blood transfusion postoperatively. Although there was a significant drop in haemoglobin and haematocrit in both the groups, on comparison, there was no significant difference in blood loss and fall in Hb levels between the groups (p > 0.001). Tranexamic acid decreases blood loss in patients undergoing TKA independent of all the other blood conserving procedures.

Practical Repair Method for Unilateral Cleft Lips: Straight-Line Advanced Release Technique.

2016-04-01

Straight-line closure repair of unilateral cleft lips was first introduced in the 1840s, and since then, many different techniques have been attempted for cleft repair. However, these methods have several disadvantages and are difficult to adopt. In this study, we describe our novel technique, known as Straight-Line Advanced Release Technique (StART), and its application in treating several cases of unilateral cleft lip. The preoperative design of the surgical method is drawn on the skin, the vermilion, and the oral mucosa. A total of 13 points are marked (points 0-12). The A flap, B flap, triangular flap, M (medial mucosal) flap, and L (lateral mucosal) flap are designed. After completion of the preoperative marking, the wide dissection is performed to separate the orbicularis oris muscle completely from the abnormally inserted bony structure and the enveloped skin-mucosal flap. The freed orbicularis oris muscle is then reconstructed with full width. After all planes of the lip wound are closed, a straight vertical skin suture line is achieved without any unnecessary transverse scar. Unilateral cleft lip repair using StART was conducted in 145 patients between 1993 and 2012. Cases of microform cleft lip were excluded. A total of 21 patients (14%) required a secondary operation on the lip after the first unilateral cheiloplasty. In all patients, satisfactory surgical outcomes were obtained with an indistinct straight-lined scar and a well-aligned lip contour. To acquire a natural and balanced shape in unilateral cleft lip repair, we recommend the novel StART.

An association between celiac disease and renal diseases has been suggested, but the results are controversial. To investigate the prevalence of celiac disease autoimmunity among individuals undergoing renal biopsies and to evaluate whether co-existent celiac autoimmunity influences the clinical outcome of the renal disease. The prevalence of celiac autoimmunity (previous diagnosis of celiac disease or positive tissue transglutaminase antibodies) was determined in 827 consecutive patients undergoing kidney biopsies due to clinical indications. Up to 15 years' follow-up data on kidney function and co-morbidities were obtained. Celiac autoimmunity was found in 45 (5.4%) patients. Among the IgA nephropathy patients, 8.2% of had celiac autoimmunity. At the time of kidney biopsy and after a median follow-up of 5 to 6 years, renal function measured by estimated glomerular filtration rate (eGFR) was inferior in IgA nephropathy patients with celiac autoimmunity compared to those without it (P=0.048 and P=0.022, respectively). The prevalence of celiac autoimmunity seems to be high in patients undergoing renal biopsies, especially in patients with IgA nephropathy. Such autoimmunity may be associated with worse renal function in IgA nephropathy. Hence the co-existence of celiac disease should be taken into consideration when treating patients with renal diseases. Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l.

1) Determine the correlation between voice handicap index and quantitative videostroboscopy for patients undergoing injection laryngoplasty for unilateral vocal paralysis; 2) assess which videostroboscopy measurements correlate best with voice handicap index in patients demonstrating progressive improvement beyond six months following injection laryngoplasty. Case series with chart review. Patients undergoing outpatient injection laryngoplasty with hyaluronic acid between 2005 and 2007. Twenty-eight patients were assessed preoperatively and postoperatively using voice handicap index and videostroboscopy. Various videostroboscopy measurements were quantified: glottic open area (ratio of open to total glottic area during closed phase of phonation), glottic closed phase (frame ratio of closed phase to total glottic cycle), supraglottic compression (percent encroachment of supraglottis onto best-fit ellipse around glottis), wave amplitude (difference in glottic open area between open and closed phases), and wave duration (number of frames per glottic cycle). Correlation coefficients were calculated using Spearman's r. One hundred seventeen separate recordings were analyzed. Correlation coefficients between voice handicap index (normalized to preoperative values) and glottic closed phase showed moderate-strong correlation (r = -0.733, P < 0.001), while glottic open area and wave duration showed weak-moderate correlation (r = 0.465, P < 0.001 and r = -0.404, P < 0.001 respectively). Other parameters showed poor correlation. A subset of 25 recordings from eight patients with progressive voice handicap index improvement beyond six months showed highest correlation with supraglottic compression (r = 0.504, P < 0.05). Voice handicap index correlates best with glottic closed phase, suggesting duration of vocal fold closure during the glottic cycle best represents patients' subjective outcome post-procedure. Progressive improvement in voice handicap index beyond six months may

Thyroplasty with arytenoid adduction, a combined procedure for treatment of unilateral vocal fold paralysis, is typically performed under local anesthesia with sedation to allow for intraoperative voice assessment. However, the need for patient immobility and suppression of laryngeal responses to surgical manipulation can make sedation-analgesia challenging. We describe our first 26 consecutive cases undergoing thyroplasty and arytenoid adduction with a standardized technique consisting of a combination of general anesthesia with tracheal intubation followed by sedation-analgesia. Most patients (69 %) were women, with age of 53 ± 15 years (mean ± SD). Neck surgery was the cause of vocal fold paralysis in 50 % of patients. Initially, general anesthesia was maintained with desflurane and remifentanil with dexmedetomidine added just before tracheal extubation. During the sedation-analgesia phase, patients received infusions of remifentanil and dexmedetomidine. Duration of general anesthesia and sedation-analgesia phases was 162 ± 68.2 and 79 ± 18.3 min, respectively. Mean (SD) wake-up time was 8.0 ± 4.0 min after desflurane discontinuation. Extubation occurred without coughing, bucking, or agitation in 96 % of patients. All the patients were able to phonate appropriately and remained comfortable after emergence. This technique allowed improved surgical conditions with reduced patient discomfort and may be advantageous for other laryngeal and neck surgeries in which intraoperative patient feedback is required.

This study examined whether racial/ethnic differences in illness perceptions exist among patients on maintenance hemodialysis. One hundred sixty-one patients with end stage renal disease (ESRD) undergoing maintenance hemodialysis (20% African Americans, 44% Hispanics, 9% Filipinos, and 27% Koreans) completed the Revised Illness Perception Questionnaire. Korean participants had higher emotional disturbance than their counterparts, whereas African-American participants had higher negative perceptions of personal intervention or medical treatment controlling their disease. This study indicates that patients from different racial/ethnic backgrounds undergoing maintenance hemodialysis may perceive their disease differently. This phenomenon could affect clinical outcomes and may require different therapeutic approaches. PMID:22480051

Postoperative hyperglycaemia of diabetic patients undergoing cardiac surgery - a clinical audit.

Previous studies have shown that hyperglycaemia is associated with postoperative complications in cardiac surgical patients. Conversely, well-controlled glucose levels are said to reduce major infectious complications in diabetic patients. The purpose of this clinical audit was to evaluate the blood glucose levels of diabetic patients undergoing cardiac surgery and to determine the effectiveness of postoperative glycaemic control. A group of 150 patients from a large Irish cardiac surgery centre was selected by convenience sampling. An audit tool was designed to capture the patients' blood glucose levels, treatment regimes and postoperative complications. The findings showed major variations between 'high', 'good' and 'borderline' blood glucose levels in the pre- and postoperative phase. Although blood glucose testing practices seemed inconsistent, mean levels measured 'borderline'. Furthermore, the treatment regimes varied greatly and suggest a lack of consensus regarding the management of postoperative hyperglycaemia. A total of 52% (n = 78) patients developed 114 complications with a level of 21.4% (n = 32) postoperative wound infections. The findings from this audit highlight the importance of regular blood glucose testing to enable early detection of hyperglycaemia and timely initiation of appropriate treatments regimes for diabetic patients undergoing cardiac surgery. Findings also show that hyperglycaemia derangement may make a difference in the recovery phase. While patients will benefit from lesser wound infections, hospitals might save costs involved with treating postoperative complications. More consistent blood glucose testing might be achieved through the use of evidence-based protocols. However, the education of staff is as important as it develops knowledge on the complex metabolic interactions of diabetic patients undergoing cardiac surgery. While this means investing in staff education and policy development, costs for daily care and expensive

To characterize trends in pain and functional outcomes and identify risk factors in patients with lumbar spinal stenosis (LSS) and neurogenic claudication undergoing the "Minimally Invasive Lumbar Decompression" (MILD) procedure. Retrospective observational cohort study. Academic multidisciplinary pain center at Stony Brook Medicine. Patients undergoing the MILD procedure from October 2010 to November 2012. De-identified perioperative, pain and function related data for 50 patients undergoing MILD were extracted from the Center for Pain Management's quality assessment database. Data included numerical rating scale (NRS), symptom severity and physical function (Zurich Claudication Questionnaire), functional status (Oswestry Disability Index [ODI]), pain interference scores (National Institutes of Health Patient-Reported Outcomes Measurement Information System [PROMIS]), and patients' self-reported low back and lower extremity pain distribution. No MILD patient incurred procedure-related complications. Average NRS scores decreased postoperatively and 64.3% of patients reported less pain at 3 months. Clinically meaningful functional ODI improvements of at least 20% from baseline were present in 25% of the patients at 6 months. Preliminary analysis of changes in PROMIS scores at 3 months revealed that pre-MILD "severe" lumbar canal stenosis may be associated with high risk of "no improvement." No such impact was observed for NRS or ODI outcomes. Overall, pain is reduced and functional status improved in LSS patients following the MILD procedure at 3 and 6 months. Given the small sample size, it is not yet possible to identify patient subgroups at risk for "no improvement." Continued follow-up of longer-term outcomes appears warranted to develop evidence-based patient selection criteria. Wiley Periodicals, Inc.

Objectives The aim of this study is to present a case of successful relief of bilateral occipital neuralgia (ON) using unilateral occipital nerve stimulation (ONS) and to discuss the possible underlying mechanisms. Materials and methods We present the case of a 59-year-old female patient with severe bilateral ON treated with unilateral ONS. We systematically reviewed previous studies of ONS for ON, discussing the possible mechanisms of ONS in the relief of ON. Results The patient reported complete pain relief after consistent unilateral ONS during the follow-up period. The underlying mechanisms may be linked to the relationship between pain and several brain regions, including the pons, midbrain, and periaqueductal gray. Conclusion ONS is an effective and safe option for treating ON. Future studies will be required to clarify the mechanisms by which unilateral occipital stimulation provided relief for bilateral neuralgia in this case. PMID:28176938

We explored the effectiveness of mirror therapy (MT) in the treatment of unilateral neglect in stroke patients. This is an open, blinded endpoint, randomized controlled trial carried out from January 2011 to August 2013. We included stroke patients with thalamic and parietal lobe lesions with unilateral neglect 48 hours after stroke. Patients were randomized to the MT group or the control group (sham MT), and both the groups received limb activation. Patients received treatment for 1-2 hours a day 5 days a week for 4 weeks. The primary outcome was unilateral neglect assessed by a blinded assessor using the star cancellation test, the line bisection test, and a picture identification task at 1, 3, and 6 months. This study was registered at http://clinicaltrials.gov (NCT 01735877). Forty-eight patients were randomized to MT (n = 27) or the control group (n = 21). Improvement in scores on the star cancellation test over 6 months was greater in the MT group (mean difference 23, 95% confidence interval [CI] 19-28; p < 0.0001). Similarly, improvement in the MT group was observed in the scores on the picture identification task (mean difference 3.2, 95% CI 2.4-4.0; p < 0.0001) and line bisection test (mean difference 8.6, 95% CI 2.7-14.6; p = 0.006). In patients with stroke, MT is a simple treatment that improves unilateral neglect. This study provides Class I evidence that for patients with neglect from thalamic and parietal lobe strokes, MT improves neglect. © 2014 American Academy of Neurology.

Prior studies have associated gross inner ear abnormalities with pediatric sensorineural hearing loss (SNHL) using computed tomography (CT). No studies to date have specifically investigated morphologic inner ear abnormalities involving the contralateral unaffected ear in patients with unilateral SNHL. The purpose of this study is to evaluate contralateral inner ear structures of subjects with unilateral SNHL but no grossly abnormal findings on CT. IRB-approved retrospective analysis of pediatric temporal bone CT scans. 97 temporal bone CT scans, previously interpreted as "normal" based upon previously accepted guidelines by board certified neuroradiologists, were assessed using 12 measurements of the semicircular canals, cochlea and vestibule. The control-group consisted of 72 "normal" temporal bone CTs with underlying SNHL in the subject excluded. The study-group consisted of 25 normal-hearing contralateral temporal bones in subjects with unilateral SNHL. Multivariate analysis of covariance (MANCOVA) was then conducted to evaluate for differences between the study and control group. Cochlea basal turn lumen width was significantly greater in magnitude and central lucency of the lateral semicircular canal bony island was significantly lower in density for audiometrically normal ears of subjects with unilateral SNHL compared to controls. Abnormalities of the inner ear were present in the contralateral audiometrically normal ears of subjects with unilateral SNHL. These data suggest that patients with unilateral SNHL may have a more pervasive disease process that results in abnormalities of both ears. The findings of a cochlea basal turn lumen width disparity >5% from "normal" and/or a lateral semicircular canal bony island central lucency disparity of >5% from "normal" may indicate inherent risk to the contralateral unaffected ear in pediatric patients with unilateral sensorineural hearing loss.

The primary objective of this study is to compare the oocyte yield in breast cancer patients undergoing controlled ovarian stimulation (COS) using letrozole and gonadotropins with patients undergoing COS with standard gonadotropins for elective cryopreservation of oocytes. Odds ratios (OR) for the number of mature oocytes were estimated. Pregnancy outcomes for breast cancer patients undergoing frozen-thawed 2-PN embryo transfers (FETs) after oncologic treatment were also noted. 220 and 451 cycles were identified in the breast cancer and the elective cryopreservation groups, respectively. Patients in the former group had lower peak estradiol levels [464.5 (315.5-673.8) pg/mL] compared to the latter [1696 (1058-2393) pg/mL; p < 0.01]. More oocytes were retrieved in the breast cancer group (12.3 ± 3.99) compared to the elective cryopreservation group (10.9 ± 3.86; p < 0.01). The odds for mature oocytes with letrozole and gonadotropins was 2.71 (95% CI 1.29-5.72; p = 0.01). Fifty-six FETs occurred in the breast cancer group. The clinical pregnancy and live birth rates per FET cycle were 39.7%, and 32.3%, respectively. Our findings suggest that COS with letrozole and gonadotropins yield more mature oocytes at lower estradiol levels compared to COS with gonadotropins alone. Breast cancer patients undergoing FET after oncologic treatment have live birth rates comparable to age-matched counterparts.

Endoscopic stenting for hilar cholangiocarcinoma: efficacy of unilateral and bilateral placement of plastic and metal stents in a retrospective review of 480 patients

Background Endoscopic biliary drainage of hilar cholangiocarcinoma is controversial with respect to the optimal types of stents and the extent of drainage. This study evaluated endoscopic palliation in patients with hilar cholangiocarcinoma using self-expandable metallic stents (SEMS) and plastic stents (PS).We also compared unilateral and bilateral stent placement according to the Bismuth classification. Methods Data on 480 patients receiving endoscopic biliary drainage for hilar cholangiocarcinoma between September 1995 and December 2010 were retrospectively reviewed to evaluate the following outcome parameters: technical success (TS), functional success (FS), early and late complications, stent patency and survival. Patients were followed from stent insertion until death or stent occlusion. Patients were divided into 3 groups according to the Bismuth classification (Group 1, type I; Group 2, type II; Group 3, type > III). Results The initial stent insertion was successful in 450 (93.8%) patients. TS was achieved in 204 (88.3%) patients treated with PS and in 246 (98.8%) patients palliated with SEMS (p < 0.001). In the intention-to-treat (ITT) analysis, the FS in patients treated with SEMS (97.9%) was significantly higher than in patients treated with PS (84.8%) (p < 0.001). Late complications occurred in 115 (56.4%) patients treated with PS and 60 (24.4%) patients treated with SEMS (p < 0.001). The median duration of stent patency in weeks (w) were as follows: 20 w in patients palliated with PS and 27 w in patients treated with SEMS (p < 0.0001). In Group 2, the median duration of PS patency was 17 w and 18 w for unilateral and bilateral placement, respectively (p = 0.0004); the median duration of SEMS patency was 24 w and 29 w for unilateral and bilateral placement, respectively (p < 0.0001). Multivariate analysis using the Poisson regression showed that SEMS placement (B = 0.48; P < 0.01) and bilateral deployment (B = 0

At present, limited experience exists on the treatment of atrial fibrillation (AF) in patients undergoing mitral valve repair (MVR) for Barlow disease. The aim of this investigation was to prospectively evaluate the radiofrequency ablation of AF in patients undergoing MVR for severe regurgitation due to Barlow disease. From January 1, 2007 to December 31, 2010, out of 85 consecutive patients with Barlow disease, 27 with AF underwent RF ablation associated with MVR. They were examined every 4 months in the first year after surgery and thereafter twice yearly. At follow-up, AF was observed in 4/25 (16.0%). NYHA (New York Heart Association) functional class improved significantly, with no patients in class III or IV (before surgery, 81.5% had been). Otherwise, among 58 patients in sinus rhythm, 6 (11%) developed AF during follow-up. No clinical or echocardiographic predictive factor was found in this subgroup. Results from our investigation suggest that radiofrequency ablation of AF in patients with Barlow disease undergoing MVR for severe regurgitation is effective and should be considered in every patient with Barlow disease and AF undergoing valve surgical repair.

Do-not-resuscitate (DNR) status has been shown to be an independent risk factor for mortality in the post-operative period. Patients with DNR orders often undergo elective surgeries to alleviate symptoms and improve quality of life, but there are limited data on outcomes for informed decision making. Retrospective cohort study. A multi-institutional setting including operating room, postoperative recovery area, inpatient wards, and the intensive care unit. A total of 566 patients with a DNR status and 316,431 patients without a DNR status undergoing elective procedures using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) from 2012. Patients undergoing elective surgical procedures. We analyzed the risk-adjusted 30-day morbidity and mortality outcomes for the matched DNR and non-DNR cohorts undergoing elective surgeries. DNR patients had significantly increased odds of 30-day mortality (OR 2.51 [1.55-4.05], p < 0.001) compared with non-DNR patients. In the DNR versus non-DNR cohort there was no significant difference in the occurrence of a number of 30-day complications, the rate of resuscitative measures undertaken, including cardiac arrest requiring CPR, reintubation, or return to the OR. The most common complications in both DNR and non-DNR patients undergoing elective procedures were transfusion, urinary tract infection, reoperation, and sepsis. Finally, the DNR patients had a significantly increased total length of hospital stay (7.65 ± 9.55 vs. 6.87 ± 9.21 days, p = 0.002). DNR patients, as compared with non-DNR patients, have increased post-operative mortality but not morbidity, which may arise from unmeasured severity of illness or transition to comfort care in accordance with a patient's wishes. The informed consent process for elective surgeries in this patient population should include a discussion of acceptable operative risk. Copyright © 2018 Elsevier Inc. All rights reserved.

The present study was designed to analyze the serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transferase, and the hematocrit in patients with chronic kidney disease who were undergoing peritoneal dialysis or hemodialysis. Twenty patients on peritoneal dialysis and 40 on hemodialysis were assessed, and the patients were matched according to the length of time that they had been on dialysis. Blood samples were collected (both before and after the session for those on hemodialysis) to measure the enzymes and the hematocrit. In the samples from the patients who were undergoing peritoneal dialysis, the aspartate and alanine aminotransferase levels were slightly higher compared with the samples collected from the patients before the hemodialysis session and slightly lower compared with the samples collected after the hemodialysis session. The levels of gamma-glutamyl transferase in the hemodialysis patients were slightly higher than the levels in the patients who were undergoing peritoneal dialysis. In addition, the levels of aminotransferases and gamma-glutamyl transferase that were collected before the hemodialysis session were significantly lower than the values collected after the session. The hematocrit levels were significantly lower in the patients who were on peritoneal dialysis compared with the patients on hemodialysis (both before and after the hemodialysis session), and the levels were also significantly lower before hemodialysis compared with after hemodialysis. The aminotransferase levels in the patients who were undergoing peritoneal dialysis were slightly higher compared with the samples collected before the hemodialysis session, whereas the aminotransferase levels were slightly lower compared with the samples collected after the session. The hematocrits and the aminotransferase and gamma-glutamyl transferase levels of the samples collected after the hemodialysis session were significantly higher than the samples collected before

Biliary lithiasis is not much frequent in paediatric patients. The manegement of cholelithiasis in patients undergoing laparoscopic cholecystectomy is still controversial. We propose the preoperatory echographic study of the biliary tree 24-48 h before surgery, as the first choice, instead of the intraoperatory cholangiography. We made a retrospective study of 42 patients undergoing laparoscopic cholecystectomy due to symptomatic biliary lithiasis during the last 15 years, with ages between 18 months and 17-years-old (mean age 9,6-years-old) and weight between 11 and 70 kg (mean weight 42 kg) at the moment of surgery. Six of them had haematological illnesses, 17 came to the hospital because of acute abdominal pain, 10 had been studied because of recurrent abdominal pain and 9 had casual diagnoses. Abdominal sonography was performed in all patients 24-48 hours before surgery. Four children were diagnosed of biliary duct lithiasis: two choledocolithiasis and two stones in the cystic duct. One of the cystic stones was extracted in the operating room and the rest resolved spontaneously. One patient presented dilatation of choledocal duct after surgery, without any stones' evidence. Also this patient resolved spontaneously. We had no complications. Biliary lithiasis is not frequent in children, even if it seems to be increasing. A few of these patients will suffer of choledocolithiasis. The intraoperatory exploration of the biliary tree during laparoscopic surgery is technically difficult due the small size of paediatric patients. Cholangiography is not always successful and can produce some important complications as pancreatitis. Preoperative sonography 24-48 hours before surgery is a safe and efficient method for the diagnosis and follow-up of paediatric patients with biliary lithiasis undergoing laparoscopic cholecystectomy. It is safe enough to be performed without intraoperatory cholangiography.

Objective: Percutaneous coronary intervention has been effective in increasing longevity of patients with cardiovascular disease. However, the evidence shows that the quality of life after the intervention is still lower than optimal level. The quality of life can be affected by various factors. The aim of this study is to determine the quality of life and its related factors in patients undergoing coronary angioplasty. Methods: This cross-sectional study was performed on 106 patients undergoing coronary angioplasty during 2015-2016. This study population included all patients who referred to a cardiac clinic in Rasht, Iran, were passed 3 months after their angioplasty. Research samples met the inclusion criteria and were willing to participate to the study, were selected gradually (continually). Research tools were a self-structured questionnaire regarding factors associated with the quality of life and the MacNew quality of life questionnaire. Data were collected through asking patients questions and using patient’s medical records. Data analysis was conducted using descriptive and inferential statistics. Results: The results of multivariate linear regression analysis showed that independent variables of age (P = 0.0001), the number of diseased vessels (P = 0.0001), and the number of comorbidities (P < 0.05) were the most important factors associated with the quality of life. Conclusion: Health-care professionals can play an effective role in promoting the quality of life of patients undergoing coronary angioplasty by modifying lifestyle based on the related factors and to provide comprehensive care programs, especially for elderly.

The impact of permanent pacemaker (PPM) on long-term clinical outcomes of patients undergoing percutaneous coronary intervention (PCI) has not been studied. PPM may increase heart failure (HF) burden on patients undergoing PCI. We recruited consecutive patients undergoing PCI and carried out a nested case-control study. Patients with confirmed PPM undergoing first PCI were identified and matched by age and sex in 1:1 fashion to patients without PPM undergoing first PCI. Clinical data were collected and analyzed. The primary endpoint outcomes were all-cause mortality and hospitalization for HF. The final analysis included 156 patients. The mean follow-up period was 4.6 ± 2.9 years. The overall all-cause mortality was 21.15%, without significant difference between the 2 groups (21.79% vs 20.51%; P = 0.85). However, the rate of HF-related hospitalization was significantly higher in patients with PPM than in controls (26.92% vs 10.26%; P = 0.008). After adjustment for hypertension, type 2 diabetes mellitus, hyperlipidemia, chronic kidney disease, stroke, left ventricular ejection fraction, brain natriuretic peptide, and acute coronary syndrome (ACS), PCI patients with PPM were still associated with a greater hospitalization rate for HF (odds ratio: 4.31, 95% confidence interval: 0.94-19.80, P = 0.061). Further analysis in the ACS subgroup showed VVI-mode pacing enhanced the risk for HF-associated hospitalization (adjusted odds ratio: 8.27, 95% confidence interval: 1.37-49.75, P = 0.02). PPM has no effect on all-cause mortality in patients undergoing first PCI but significantly increases the HF-associated hospitalization rate, especially in ACS patients. © 2016 Wiley Periodicals, Inc.

The aim of this study was to investigate the relationships between personality and joint-specific function, general physical and general mental health in patients undergoing total hip (THA) and knee arthroplasty (TKA). One hundred and eighty-four patients undergoing THA and 205 undergoing TKA were assessed using the Eysneck Personality Questionnaire, brief version (EPQ-BV). General physical and mental health was measured using the Short-Form 12 (SF-12) questionnaire and the EuroQol (EQ-5D). Joint-specific function was measured using the Oxford hip or knee score. The "unstable introvert" personality type was associated with poorer pre-operative function and health in patients with hip arthrosis. In patients with knee arthrosis, there was poorer general health in those with "stable extrovert" and "unstable introvert" types. Personality was not an independent predictor of outcome following TKA or THA. The main predictor was pre-operative function and health. Comorbidity was an important covariate of both pre-operative and postoperative function. Personality may play a role in the interaction of these disease processes with function and health perception. It may also affect the response and interpretation of psychometric and patient-reported outcome measures. It may be important to characterise and identify these traits in potential arthroplasty patients as it may help deliver targeted education and management to improve outcomes in certain groups.

To characterize the outcomes of gynecologic oncology patients undergoing small bowel follow-throughs (SBFTs) with Gastrografin at our institution. We identified all gynecologic oncology patients undergoing an SBFT from January 2004 to December 2009. We characterized the SBFT as normal, delayed transit, partial obstruction, or complete obstruction. Patient outcomes were correlated with the SBFT results. Seventy patients underwent 79 SBFT examinations with Gastrografin to evaluate their bowel dysfunction. The overall rate of operative intervention was 23%. A total of 69% of patients with a complete obstruction underwent surgery as compared to 21% of patients with a partial obstruction (p = 0.002). Return of bowel function was significantly longer in patients with complete obstructions as compared to patients with partial obstructions (48 vs. 8 hours, p = 0.006). Length of stay was longest in patients with complete obstructions. The majority of patients with a complete obstruction on SBFT will require surgical intervention and have a protracted hospital stay. Patients with delayed transit or a partial obstruction on SBFT usually will have resolution of their bowel dysfunction with conservative management.

This case report depicts the clinical course of a female patient with unilateral retinitis pigmentosa, who first presented at the age of 12 years. Fundus photography at the time revealed unilateral pigmentary retinopathy, which was associated with extinguished electroretinogram (ERG) signal. At 35 years of age, fundus examination revealed deterioration of pre-existing unilateral pigmentary retinopathy with progressive visual field defect detected on Goldmann visual field testing. ERG findings remained unchanged and multifocal ERG showed unilateral decrease in amplitude in the affected eye. The patient was referred for genetic counselling. Next-generation sequencing identified a deleterious heterozygous c.118T>G (p.Cys40Gly) mutation in the CLRN1 gene. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Objective To identify the subtle change of postural control in elderly patients with unilateral knee osteoarthritis (OA) with computerized dynamic posturography. Method Twenty-two healthy women and twenty-six women with unilateral knee OA, aged 60 and over, were enrolled. The computerized posturographic measures included a weight bearing pattern during squatting and sit-to-stand, sway velocity of center of gravity (COG) during one leg standing, on-axis velocity and directional control of COG during rhythmic weight shift, rising index during sit-to-stand, end sway during tandem walk, and movement time during step up/over. Results It was shown that patients bore significantly less weight on the affected side during the 30° and 60° squat and sit-to-stand. Sway velocity of COG during one leg standing was greater whereas the on-axis velocity and directional control during the front/back rhythmic weight shift were significantly lower in the patient group. The rising index during sit-to-stand was significantly lower and movement time during step up/over with the affected side was significantly longer in patients. Conclusion This study demonstrated in detail a decline of postural balance by utilizing computerized posturography in elderly women with unilateral knee OA. They had less weight-bearing, more sway, and less ability of intentional postural control on the affected side. PMID:23185725

Patients undergoing primary hepatic resection often develop hemostatic dysfunction associated with cirrhosis. We retrospectively surveyed pre- and postoperative prothrombin time (PT) and the PT expressed as international normalized ratio (PT-INR) in 39 patients undergoing primary liver resection. We also compared PT changes between primary and metastatic cancer cases (8 cases). Postoperative PT-INR was 1.40 ± 0.38, which was significantly prolonged compared to preoperative PT-INR of 1.08 ± 0.07. Preoperative PT was over 70% in all 39 patients undergoing primary liver resection, whereas postoperative PT was less than 60% in 13 of 39 patients. No significant difference was found in preoperative PT-INR between primary and metastatic cancer cases, but postoperative PT-INR was significantly prolonged in primary cancer cases. Patients undergoing primary liver resection are susceptible to hemostatic dysfunction, even with preoperative PT levels within normal limits.

Generally, before being operated on, patients will be given informal information by the healthcare providers involved in the care of the patients (doctors, nurses, ward clerks, or healthcare assistants). This information can also be provided formally in different formats including written information, formal lectures, or audio-visual recorded information. To compare the benefits and harms of formal preoperative patient education for patients undergoing laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2, 2013), MEDLINE, EMBASE, and Science Citation Index Expanded to March 2013. We included only randomised clinical trials irrespective of language and publication status. Two review authors independently extracted the data. We planned to calculate the risk ratio with 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) or standardised mean difference (SMD) with 95% CI for continuous outcomes based on intention-to-treat analyses when data were available. A total of 431 participants undergoing elective laparoscopic cholecystectomy were randomised to formal patient education (215 participants) versus standard care (216 participants) in four trials. The patient education included verbal education, multimedia DVD programme, computer-based multimedia programme, and Power Point presentation in the four trials. All the trials were of high risk of bias. One trial including 212 patients reported mortality. There was no mortality in either group in this trial. None of the trials reported surgery-related morbidity, quality of life, proportion of patients discharged as day-procedure laparoscopic cholecystectomy, the length of hospital stay, return to work, or the number of unplanned visits to the doctor. There were insufficient details to calculate the mean difference and 95% CI for the difference in pain scores at 9 to 24 hours (1 trial; 93 patients); and we did not identify clear evidence of

Presurgical Unilateral Cleft Lip Anthropometrics and the Presence of Dental Anomalies.

To investigate associations between cleft lip anthropometrics and dental anomalies in the permanent dentition in unilateral cleft lip patients. Retrospective cross-sectional study. Children with unilateral clefts of the lip, with or without cleft palate. Anthropometric lip measurements, made immediately prior to lip repair, were available for each patient. The presence of dental anomalies in the permanent dentition was assessed radiographically. The presence of associations between anthropometric lip measurements and prevalence rates of different dental anomalies were determined using logistic regression analyses. In the 122 included patients, the cleft lateral lip element was deficient in height in 80% and in transverse length in 84% of patients. Patients with more deficient cleft side lateral lip height and less deficient cleft side lateral lip transverse length were more likely to present with cleft side maxillary lateral incisor agenesis. On the other hand, patients with a less deficient cleft side lateral lip height and more deficient cleft side lateral lip transverse length were more likely to present with a cleft side supernumerary maxillary lateral incisor. When looking only at incomplete clefts, the cleft side lateral lip transverse length deficiency was more predictive of the presence of supernumerary maxillary lateral incisors (P = .030), while for complete clefts, the cleft side lateral lip height deficiency was more predictive of the presence of maxillary lateral incisor agenesis (P = .035). In patients with unilateral clefts, cleft lip anthropometrics have a predictive role in determining the occurrence of dental anomalies.

Should patients with Björk-Shiley valves undergo prophylactic replacement?

About 85,000 patients have undergone replacement of diseased heart valves with prosthetic Björk-Shiley convexo-concave (CC) valves. These valves are prone to fracture of the outlet strut, which leads to acute valve failure that is usually fatal. Should patients with these valves undergo prophylactic replacement to avoid fracture? The incidence of strut fracture varies between 0% and 1.5% per year, depending on valve opening angle (60 degrees or 70 degrees), diameter (less than 29 mm or greater than or equal to 29 mm), and location (aortic or mitral). Other factors include the patient's life expectancy and the expected morbidity and mortality associated with reoperation. We have used decision analysis to identify the patients most likely to benefit from prophylactic reoperation. The incidence of outlet strut fracture was estimated from the data of three large studies on CC valves, and stratified by opening angle, diameter, and location. A Markov decision analysis model was used to estimate life expectancy for patients undergoing prophylactic valve replacement and for those not undergoing reoperation. Prophylactic valve replacement does not benefit patients with CC valves that have low strut fracture risks (60 degrees aortic valves and less than 29 mm, 60 degrees mitral valves). For most patients with CC valves that have high strut fracture risks (greater than or equal to 29 mm, 70 degrees CC), prophylactic valve replacement increases life expectancy. However, elderly patients with such valves benefit from prophylactic reoperation only if the risk of operative mortality is low. Patient age and operative risk are most important in recommendations for patients with CC valves that have intermediate strut fracture risks (less than 29 mm, 70 degrees valves and greater than or equal to 29 mm, 60 degrees mitral valves). For all patients and their doctors facing the difficult decision on whether to replace CC valves, individual estimates of operative mortality risk that

In this meta-analysis, we reviewed observational studies investigating differences in intelligence quotient (IQ) scores of children with unilateral hearing loss compared to children with normal hearing. PubMed Medline, Cumulative Index to Nursing and Allied Health Literature, Embase, PsycINFO. A query identified all English-language studies related to pediatric unilateral hearing loss published between January 1980 and December 2014. Titles, abstracts, and articles were reviewed to identify observational studies reporting IQ scores. There were 261 unique titles, with 29 articles undergoing full review. Four articles were identified, which included 173 children with unilateral hearing loss and 202 children with normal hearing. Ages ranged from 6 to 18 years. Three studies were conducted in the United States and one in Mexico. All were of high quality. All studies reported full-scale IQ results; three reported verbal IQ results; and two reported performance IQ results. Children with unilateral hearing loss scored 6.3 points lower on full-scale IQ, 95% confidence interval (CI) [-9.1, -3.5], P value < 0.001; and 3.8 points lower on performance IQ, 95% CI [-7.3, -0.2], P value 0.04. When investigating verbal IQ, we detected substantial heterogeneity among studies; exclusion of the outlying study resulted in significant difference in verbal IQ of 4 points, 95% CI [-7.5, -0.4], P value 0.028. This meta-analysis suggests children with unilateral hearing loss have lower full-scale and performance IQ scores than children with normal hearing. There also may be disparity in verbal IQ scores.

A major concern for patients undergoing reverse total shoulder arthroplasty (RTSA) is managing toileting after surgery. The goals of this systematic review of RTSA studies were to determine the following: (1) the percentage of patients who can manage toileting, (2) their degree of difficulty with toileting, and (3) the percentage of patients who can manage toileting after bilateral versus unilateral RTSA. Medline, EMBASE, Google Scholar, and the Cochrane Central Register of Controlled Trials were searched for studies reporting the ability to manage toileting after RTSA. Six studies with at least 12 months of follow-up were included, yielding 183 patients (105 unilateral RTSA, 78 bilateral RTSA). We pooled patient data and calculated the weighted mean proportion of patients able to manage toileting, those who reported difficulty, and those able to manage toileting after unilateral versus bilateral RTSA. Statistical significance was set at P < 0.05. Most patients (92%; 95% confidence interval, 87-95%) were able to manage toileting after RTSA. Some degree of difficulty with toileting was reported for 20% of all shoulders. Almost all patients with bilateral RTSA were able to manage toileting with at least one arm (weighted mean proportion 97%; 95% confidence interval, 88-99%). There was no significant difference in the proportion of patients able to manage toileting after unilateral versus bilateral RTSA (P = 0.08). Only 3% of all papers published on the clinical results of RTSA by June 2017 reported upon toileting after the procedure. With the available evidence, most patients were able to manage toileting after RTSA, although one-fifth reported some degree of difficulty. Ability to manage toileting was similar after unilateral versus bilateral RTSA. In the future, this variable should be a standard question after shoulder arthroplasty. IV.

In total, 1386 paraffin embedded radical prostatectomy specimens from patients with clinically localized prostate cancer (PCa) excised between 2002-06 were analyzed. Pathologic assessment paid particular attention to laterality and percentage of tumor involvement (PTI) along with pathologic Gleason Score (pGS). Completely unilateral cancers were identified in 254 (18.3%) patients, and in 39% cases of them the signs of clinically significant PCa were revealed. The majority of unilateral tumors (72%) were low volume with a PTI of < or =5. This study suggests that only a select group of men diagnosed with PCa have completely unilateral cancers that would be amenable to focal ablation therapy targeting 1 lobe. Further study is needed to develop predictive models for those patients likely to have small, unilateral cancers that may be amenable to focal therapy.

The purpose of this study was to assess the extent to which patients undergoing flexible bronchoscopy (FOB) experience pain and to identify patient factors and process of care factors that are associated with pain. We conducted a prospective cohort study on 481 patients undergoing FOB. Overall control of pain during FOB was the primary outcome. The mean age of the patients was 48 yr, 50% were male, and 32% required supplemental oxygen prior to FOB. Pain control was excellent in 36% of patients, but 10% considered it to be fair or poor. Patient factors associated with excellent pain control were excellent health (versus poor health, OR = 6.25 [95% CI, 2.28-16.67]), more education (college education versus high school education, OR = 1.72 [95% CI, 1.05-2.86]), and not having asthma (OR = 2.86 [95% CI, 1.09-7.14]). Process of care factors associated with excellent pain control were not being bothered by scope insertion (versus bothered, OR = 3.65 [95% CI, 1.99-6.98]), no memory of FOB (versus some memory, OR = 2.33 [95% CI, 1.24-4.44]), and higher ratings of information about the procedure (per 1-point increase on a 12-point scale, OR = 1.57 [95% CI, 1.41-1.78]). This is the first large-scale, prospective study to evaluate patient and process of care factors that influence pain control during FOB. It demonstrated that there are patient characteristics and process of care factors that need to be considered when evaluating pain during bronchoscopy. Improved preparation of patients with lower education, inferior health status, and asthma may lead to decreased pain during FOB. Bronchoscopists may be able to reduce pain during FOB by identifying methods to decrease pain on scope insertion, by improving the information provided to patients, and by achieving greater levels of amnesia during FOB.

To evaluate the effects of an intensive postoperative physiotherapy program focused on respiratory exercises in patients undergoing lobectomy by open thoracotomy. Quasi-experimental study. Tertiary referral academic hospital. 208 patients undergoing lobectomy by open thoracotomy. Control group patients (n=102) received standard medical/nursing care, and experimental group patients (n=106) added to the standard clinical pathway a daily physiotherapy program focused on respiratory exercises until discharge. Analyzed outcomes were the frequency of postoperative pulmonary complications (PPCs) more amenable to physiotherapy (pneumonia, atelectasis and respiratory insufficiency) and length of hospital stay (LOS). Both groups were comparable regarding preoperative and surgical characteristics. Incidence of PPCs was 20.6% in control and 6.6% in experimental group (P=.003). Median (IQR) LOS in control group was 14 (7) days (Huber M estimator 14.21) and 12 (6) days (Huber M estimator 12.81) in experimental. Logistic regression model identified the evaluated physiotherapy program (P=.017; EXP [B] 95% CI 0.081-0.780) and % FEV1 (P=.042; EXP [B] 95% CI 0.941-0.999) as protective factors for the development of PPCs in patients undergoing lobectomy. Implementing a postoperative intensive physiotherapy program focused on respiratory exercises reduces the risk of PPCs and resultant LOS on patients undergoing lobectomy. Copyright © 2016 SEPAR.

Myocardial infarction and subsequent death in a patient undergoing robotic prostatectomy.

PubMed

Thompson, Judy

2009-10-01

A 52-year-old patient, ASA physical status IV, undergoing a radical prostatectomy for cancer with a robotic system had a cardiac arrest 3 hours into the case. All attempts to resuscitate were unsuccessful, and several hours later he was pronounced dead. Underlying patient comorbidity and procedural issues contributed to the patient's death. The patient had a history of coronary artery disease that required the placement of drug-eluting stents 2 years before this surgical procedure. The preoperative cardiac evaluation and pharmacological management of patients with drug-eluting coronary stents are reviewed. There are a number of positional and technical considerations for patients undergoing robotic surgical procedures, especially in relation to the requirement of low-lithotomy and steep Trendelenburg positions. The cardiac and respiratory systems are especially vulnerable to the extreme and lengthy head-down position. The needed positioning, combined with the problems associated with insufflation, presents a unique challenge in anesthetic management. This course reviews the current literature on the surgical implications for patients with drug-eluting stents and the physiologic factors related to position and pneumoperitoneum and their associated stressors. By using a review of the contemporary literature, a best-evidence approach to anesthetic management is reviewed.

Background Breast reconstruction is associated with multiple risk factors for venous thromboembolism. However, the incidence of deep vein thrombosis in patients undergoing breast reconstruction is uncertain. Objective The aim of this study was to prospectively evaluate the incidence of deep vein thrombosis in patients undergoing breast reconstruction using autologous tissue transfer and to identify potential risk factors for deep vein thrombosis. Methods Thirty-five patients undergoing breast reconstruction were enrolled. We measured patients' preoperative characteristics including age, body mass index (kg/m 2 ), and risk factors for deep vein thrombosis. The preoperative diameter of each venous segment in the deep veins was measured using duplex ultrasound. All patients received intermittent pneumatic pump and elastic compression stockings for postoperative thromboprophylaxis. Results Among the 35 patients evaluated, 11 (31.4%) were found to have deep vein thrombosis postoperatively, and one patient was found to have pulmonary embolism postoperatively. All instances of deep vein thrombosis developed in the calf and were asymptomatic. Ten of 11 patients underwent free flap transfer, and the remaining one patient received a latissimus dorsi pedicled flap. Deep vein thrombosis incidence did not significantly differ between patients with a free flap or pedicled flap (P = 0.13). Documented risk factors for deep vein thrombosis demonstrated no significant differences between patients with and without deep vein thrombosis. The diameter of the common femoral vein was significantly larger in patients who developed postoperative deep vein thrombosis than in those who did not ( P < 0.05). Conclusions The morbidity of deep vein thrombosis in patients who underwent breast reconstruction using autologous tissue transfer was relatively high. Since only the diameter of the common femoral vein was predictive of developing postoperative deep vein thrombosis, postoperative

Patients with unilateral cleft lip and palate (CLP) deformities commonly develop nasal airway obstruction, necessitating septoplasty at the time of definitive rhinoplasty. We assessed the contribution of the bony septum to airway obstruction using computed tomography (CT) and cone beam CT (CBCT). A 2-year retrospective review of all subjects with unilateral CLP who underwent CBCT imaging (n = 22) and age-matched controls (n = 9) who underwent CT imaging was conducted. Control CT scans were used to determine the segment of nasal septum comprised almost entirely of bone. The CBCT of the nasal airway was assessed using Dolphin software to determine the contribution of the bony septum to septal deviation and airway obstruction. The nasal septum posterior to the midpoint between anterior and posterior nasal spine is comprised of 96% bone. The nasal airway associated with this posterior bony segment was 43.1% (P < 0.001) larger by volume on the non-cleft side in patients with unilateral CLP. The average septal deviation within the posterior bony segment was 5.4 mm, accounting for 74.4% of the maximal deviation within the nasal airway. The average airway stenosis within the posterior bony nasal airway was 0.45 mm (0-2.2 mm). In patients with unilateral CLP, the bony nasal septum can demonstrate significant deviation and airway stenosis. Surgeons should consider a bony septoplasty in their treatment algorithm in unilateral CLP patients who have reached skeletal maturity.

To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours. Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled. Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded. Computed tomography imaging is a valuable aid to decisions regarding additional procedures needed to optimise access to the pituitary fossa.

Masseter muscle hypertrophy is a rare condition of idiopathic cause. It clinically presents as an enlargement of one or both masseter muscles. Most patients complain of facial asymmetry; however, symptoms such as trismus, protrusion, and bruxism may also occur. Several treatment options reported for masseter hypertrophy are present, which range from simple pharmacotherapy to more invasive surgical reduction. Keloid scar with unilateral masseter hypertrophy is a rarely seen in clinical practice. This paper reports a case of unilateral masseter hypertrophy with keloid scar in the angle of the mandible for which surgical treatment was rendered to the patient by using a single approach.

Benign Episodic Unilateral Mydriasis in a Flight Nurse.

Schiemer, Anthony

2017-05-01

Benign episodic unilateral mydriasis is one cause of anisocoria. This phenomenon is thought to be related to an imbalance between the sympathetic and parasympathetic nervous systems. There is a documented association with migraines, but asymptomatic cases have also been reported. A challenge with all cases is the level of investigation required to exclude more sinister causes of nervous system dysfunction. In a dynamic flight environment, additional considerations need to be made, such as varying light levels and use of night vision devices. A 27-yr-old woman on deployment to Afghanistan as a flight nurse presented to the role one clinic with right-sided mydriasis. The patient denied headache or any history of migraines. A dilated right pupil that was reactive to light was found on exam. Symptoms and exam findings resolved shortly after initial presentation. We consulted an ophthalmologist who requested patient transfer for review. He made a diagnosis of benign episodic unilateral mydriasis. There are a variety of causes for anisocoria. A thorough history and examination are required to avoid unnecessary investigations that may not be locally available in the more austere deployed military settings. From an operational perspective, the decision needs to be made regarding the maintenance of flight status. Consideration needs to be given to patient care capability when treating a flight nurse. In cases of rapid resolution such as this, removal from operational status is not reasonable should a clinician be confident of the diagnosis.Schiemer A.

Marriage confers various health advantages in the general population. However, the added value of marriage among patients who undergo percutaneous coronary intervention (PCI) beyond the standard cardiovascular risk factors is not clear. This study aimed to assess the effects of marital status on outcomes of patients undergoing elective or urgent PCI. Clinical observational analysis of consecutive patients undergoing elective or urgent PCI from 1993 to 2011 was performed. Patients were stratified by marital status, comparing married to unmarried patients. Clinical outcome up to 12 months was obtained by telephone contact or office visit. A total of 11,216 patients were included in the present analysis; 55% were married and 45% unmarried. Significant differences in baseline characteristics were noted, including a lower prevalence of hypertension (86% vs 88%), diabetes (34% vs 38%), and smoking (19% vs 25%) among married vs unmarried patients, respectively (P < .001). However, married patients had a higher prevalence of hypercholesterolemia and family history of coronary artery disease. Early and late major adverse cardiac event rates were significantly lower for married vs unmarried patients up to 1 year (13.3% vs 8.2%, P < .001). Married status was independently associated with improved outcome in multivariable analysis (hazard ratio 0.7, 95% CI 0.6-0.9). Married patients who undergo urgent or elective PCI have superior short- and long-term outcomes up to 1 year when compared with unmarried patients. These benefits persist after adjustment for multiple traditional cardiovascular risk factors. © 2013.

While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery. Stage of chronic kidney disease was based on estimated glomerular filtration rate and National Kidney Foundation - Kidney Disease Outcomes Quality Initiative guidelines. A total of 497 patients undergoing transradial percutaneous coronary interventions were included. Over 70.4% (350/497) of the patients had chronic kidney disease. Stage II chronic kidney disease was observed in 243 (69%) patients (estimated glomerular filtration rate = 76.0 ± 8.4 mL/min). Stage III was observed in 93 (27%) patients (estimated glomerular filtration rate = 49 ± 7.5 mL/min). Stage IV chronic kidney disease was observed in 5 (1%) patients (estimated glomerular filtration rate = 25.6 ± 4.3 mL/min) and Stage V chronic kidney disease was observed in 9 (3%) patients (estimated glomerular filtration rate = 9.3 ± 3.5 mL/min). Overall, 107 of 350 patients (30%) had advanced chronic kidney disease, that is, stage III-V chronic kidney disease. Importantly, 14 of the 107 (13%) patients had either stage IV or V chronic kidney disease. This study finds that nearly one-third of the patients undergoing transradial percutaneous coronary interventions have advanced chronic kidney disease. Because many of these patients may require dialysis, the use of radial artery to conduct percutaneous coronary interventions must be carefully considered in chronic kidney disease population.

To examine the prevalence of different types of dental anomalies in children with nonsyndromic cleft lip, unilateral cleft lip-palate, and bilateral cleft lip-palate. A sample of 90 patients (aged 4-20 years) affected by isolated cleft lip, unilateral and bilateral cleft lip and palate was examined. Cleft patients were classified into one of three groups according to cleft type: (1) Unilateral Cleft Lip-Palate, (2) Bilateral Cleft Lip-Palate, and (3) Cleft Lip. Intraoral exams, panoramic radiographs and dental casts, were used to analyse the prevalence of the various dental anomalies included in this study. There were no statistically significant differences between patients with cleft lip, unilateral cleft lip and palate and bilateral cleft lip and palate. The congenital absence of the cleft-side lateral incisor was observed in 40% of the sample, and a total of 30% patients showed supernumerary teeth at the incisors region. Second premolar agenesis was found in 4.4% of patients, whereas in 18.9% of the sample there was an ectopic dental eruption. Lateral or central incisors rotation was noted in 31.1% of the sample, while shape anomaly, lateral incisor microdontia, and enamel hypoplasia were detected respectively in 25.6%, 5.6% and 18.9% of cleft patients. High prevalence of different dental anomalies in children with cleft lip and unilateral and bilateral cleft lip and palate has been confirmed. This study, in particular, shows the presence of ectopic and rotated teeth in the cleft area.

Background Patients undergoing hemodialysis frequently report pain with multifactorial causes, not limited to that experienced directly from hemodialysis treatment. Their pain may be nociceptive, neuropathic, somatic or visceral in nature. Despite this, pain in this population remains under-recognized and under-treated. Although several tools have been used to measure pain in patients undergoing hemodialysis as reported in the literature, none of them have been validated specifically in this population. The objective for this review was to compare and contrast these pain assessment tools and discuss their clinical utility in this patient population. Methods To identify pain assessment tools studied in patients undergoing hemodialysis, a literature search was performed in PubMed and Medline. An expert panel of dialysis and pain clinicians reviewed each tool. Each pain assessment tool was assessed on how it is administered and scored, its psychometric properties such as reliability, validity and responsiveness to change, and its clinical utility in a hemodialysis population. Brief Pain Inventory, McGill Pain Questionnaire, Pain Management Index, Edmonton Symptom Assessment System, Visual Analogue Scale and Faces Pain Scale were evaluated and compared. Results This assessment will help clinicians practicing in nephrology to determine which of these pain assessment tools is best suited for use in their individual clinical practice. PMID:25852910

Objectives: High doses of chemotherapy generate DNA damage in patients undergoing bone marrow transplantation (BMT), due to the production of reactive oxygen species (ROS). In order to evaluate the local defensive effectiveness of the patient undergoing BMT, the concentrations of the antioxidants superoxide dismutase (SOD) and uric acid (UA) were measured in saliva. Study Design: Basal saliva samples were collected from 20 patients undergoing BMT at the Oncology Department, Sanatorio Allende (Córdoba), in the stages: initial, prior to conditioning therapy (I); middle: 7 to 10 days after BMT (M) and final stage, 30 days after discharge from isolation (F). SOD levels were determined using a RANDOX kit (RANSOD superoxide dismutase manual), and for uric acid enzymatic UOD / PAP spectrophotometric method, ( Trinder Color Kit , Wiener Lab) was used. Results: 85% of the patients developed oral mucositis. SOD concentration in the M stage was significantly higher (p<0.01) compared with stage I, and it reversed in stage F. UA concentration was significantly lower (p<0.001) in stage M compared with stage I, and in stage F it recovered the initial values. Conclusions: SOD increase in stage M coincided with the appearance of mucositis, which could be interpreted as a defensive mechanism of saliva against oxidative stress produced by chemotherapy. UA decrease in stage M would favour the development of higher degrees of mucositis. Key words:Bone marrow transplantation, mucositis, superoxide dismutase, uric acid. PMID:24608218

Background: The pterional approach is the most common for AComm aneurysms, but we present a unilateral approach to a midline region for addressing the AComm complex. The pure subfrontal approach eliminates the lateral anatomic dissection requirements without sacrificing exposure. The subfrontal approach is not favored in the US compared to Asia and Europe. We describe our experience with the subfrontal approach for AComm aneurysms treated at a single institution. Methods: We identified 28 patients treated for AComm aneurysms through the subfrontal approach. Patient records and imaging studies were reviewed. Demographics and case data, as well as clinical outcome at 6 weeks and 1 year were collected. Results: Mean patient age was 48 (range 21–75) years and 64% suffered subarachnoid hemorrhage (SAH). All aneurysms were successfully clipped. Gyrus rectus was resected in 57% of cases, more commonly in ruptured cases. Intraoperative rupture occurred in 11% of cases. The average operative time was 171 minutes. There were two patient deaths. Ninety-two percent of patients had a Glasgow Outcome Scale (GOS) of 5 at 6 weeks. All unruptured patients had a GOS of 5. At 12 months, 96% of all patients had a GOS of 5. Conclusions: The subfrontal approach provides an efficient avenue to the AComm region, which reduces opening and closing friction but still yields a comprehensive operative window for access to the anterior communicating region.

Anxiety is the most frequent emotional reaction to the chronic somatic disease. However, little is known about anxiety and coping strategies in patients with end-stage renal disease (ESRD) undergoing renal replacement therapies (RRTs). The purpose of the study was to assess the intensity and determinants of anxiety in patients treated with different RRTs in comparison with end-stage breast cancer patients and healthy controls. The study involved (1) ESRD patients undergoing different RRTs: 32 renal transplant recipients, 31 maintenance haemodialysis and 21 chronic peritoneal dialysis patients, (2) women with end-stage breast cancer (n = 25) and (3) healthy persons (n = 55). We used State-Trait Anxiety Inventory, Scale of Personal Religiousness, Mental Adjustment to Cancer Scale, Rotterdam Symptom Checklist with reference to medical history. The data thus obtained were analysed using the analysis of variance, the Tukey's HSD post hoc test and Spearman's rank correlation coefficient. Both ESRD and breast cancer patients revealed higher level of anxiety state and trait than healthy controls; however, there was no statistically significant difference found between both findings. There was a tendency towards higher levels of anxiety state in breast cancer patients when compared to ESRD patients undergoing the RRT treatment and for both groups non-constructive coping strategies correlated with the levels of anxiety state. With ESRD patients undergoing RRTs, the intensity of anxiety state did not depend on the mode of treatment but on the correlation between the levels of anxiety and the general quality of their life, psychological condition and social activity. In patients with advanced somatic disease (ESRD and end-stage breast cancer), non-constructive strategies of coping with the disease require further evaluation and possibly psychological support.

The prevention and treatment of peritonitis in patients undergoing peritoneal dialysis is often complicated by several factors, including nephrotoxicity, requirement for hospitalization, parenteral antibiotic therapy, and infection caused by resistant microorganisms. Ciprofloxacin, a new carboxyquinolone derivative, may offer the advantages of oral administration, a broad spectrum of antibacterial activity, and safety for the management of these patients. The pharmacokinetics of ciprofloxacin in serum and peritoneal fluid of eight adult patients undergoing chronic ambulatory peritoneal dialysis (CAPD) were investigated. Each patient ingested a single 750-mg dose of ciprofloxacin, and drug concentrations were measured by high-pressure liquid chromatography in serum and peritoneal fluid for 48 h after the dose. Serum concentrations reached a mean peak of 3.6 micrograms/ml 1 to 2 h after the oral dose. The mean terminal serum half-life was 16.8 h, and the mean peritoneal fluid/serum concentration ratio was 0.64. The mean peak ciprofloxacin concentration in peritoneal fluid was 1.3 micrograms/ml, and the bioactivity of the drug in peritoneal fluid was confirmed. These data indicated that therapeutic concentrations of ciprofloxacin against bacterial pathogens commonly associated with peritonitis in CAPD patients may be achievable in the peritoneal fluid after oral administration to patients undergoing CAPD. In addition, the pharmacokinetic data provide guidelines for further clinical studies of oral ciprofloxacin in CAPD patients. PMID:2944477

Eight indicators of unilateral pregnancy.

PubMed

Melchionne, Kevin

2010-12-01

Unintended pregnancy often leads to undesirable outcomes for both mothers and children. However, the definition of unintended pregnancy in the sociology of family formation has been restricted to the intentions of mothers. The intentions of fathers--and, with them, the possible role of disagreement about pregnancy intention--remain outside most conceptual frameworks and research programs. This article draws together a number of indicators of unilateral pregnancy in research on contemporary family formation in the United States. Studies of pregnancy intendedness and contraceptive use consistently provide evidence suggesting a significant role for unilateral pregnancy in family formation. Working on the assumption that unilateral pregnancy presents great potential for social dislocation, this article argues for the integration of the concept of unilateral pregnancy into the theoretical framework informing research on family formation.

Virchow-Robin space (VRS) dilatation is related to many pathologic conditions, mostly associated with vascular abnormalities. White matter lesions (WMLs) are commonly seen on brain magnetic resonance imaging (MRI) with advancing age and generally considered as potential markers for vascular disease. To investigate if asymmetric dilatation of VRSs and WMLs are associated with unilateral internal carotid artery stenosis (ICAS) and to test the relationship between dilated VRSs and common vascular risk factors. Twenty-nine patients (18 men, 11 women; mean age, 68.62 years) with unilateral ICAS (≥70% carotid stenosis) undergoing carotid endarterectomy were identified for this Health Insurance Portability and Accountability Act (HIPAA) compliant prospective study and assessed with brain MRI. Two experienced radiologists scored VRSs and WMLs and evaluated old infarcts, chronic lacunar infarcts, and cerebral atrophy. Asymmetry of WML and VRS scores between two cerebral hemispheres was assessed and associations between VRS scores, WML scores, and explanatory variables (e.g. age, sex, vascular risk factors, and atrophy) were tested. In this study, WMLs and basal ganglia VRSs were significantly greater in the unilateral hemisphere with ICA stenosis than contralateral hemisphere. Basal ganglia VRSs were associated with WMLs and internal cerebral atrophy. No association between the severity of VRSs and vascular risk factors was found. ICA stenosis may contribute as a factor in the development of WMLs and dilatation of VRSs by causing chronic hypoperfusion. VRS dilatation may be an additional MRI marker of ICAS. © The Foundation Acta Radiologica 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Background: Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery. Objectives: To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination. Patients and Methods: This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study. Results: The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination. Conclusions: There is a risk for constipation after abdominal surgery. Postoperative practices are effective on the risk of constipation. PMID:26380107

To compare the effects of contralesional sensory cueing and limb activation with that of sham control in the treatment of unilateral neglect after stroke. A randomized, single-blinded, sham-controlled pilot study. Two rehabilitation hospitals. Forty subacute left hemiplegic stroke inpatients with unilateral neglect. Participants were assigned randomly to 1 of 2 groups. The experimental group wore a wristwatch cueing device over the hemiplegic arm for three hours a day, five days per week, for three weeks, and also underwent conventional rehabilitation. Patients were encouraged to move their hemiplegic arm five consecutive times after each prompt. The sham group underwent the same rehabilitation process, except they wore a sham device. Neglect, arm motor performance, and overall functioning were assessed pre- and posttraining, and at follow-up. There were no significant differences between groups in outcome measures except the neglect drawing tasks (p = 0.034) (the mean gain score from baseline to follow-up assessment was 5.2 (3.7) in the experimental group and 1.9 (3.5) in the sham group), across three time intervals. The experimental group showed greater improvement in arm motor performance than did the sham group. The results did not confirm that sensory cueing and limb activation treatment is effective when compared with those receiving placebo to reduce unilateral neglect, but it might be useful for promoting hemiplegic arm performance in stroke patients.

Treatment-resistant major depression (MDD) and obsessive-compulsive disorder (OCD) remain a major cause of suffering and disability. These disorders may be treated with functional neurosurgery that almost always is bilateral but some patients might benefit from unilateral procedures. We performed a unilateral right anterior capsulotomy (AC) in a 45-year-old right-handed woman with MDD and comorbid OCD. This unilateral procedure was based on the results of neuropsychological testing and an 18-Fluorodeoxyglucose positron emission tomography (FDG-PET) that revealed right hemisphere deficits in this patient. Following surgery, Hamilton Depression scale (HAM-D) decreased 57% at 1 and 2 years and 54% at 3 years and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) decreased 58% at 1 year, 77% at 2 years, and 96% at 3 years. There was a slight decrement of verbal memory and phonemic fluency after the procedure that could also be related to changes in medication. Right basal ganglia abnormalities revealed by FDG-PET remained unchanged 16 months postoperatively. Overall this unilateral right AC was effective for the treatment of this woman's disorders with minimal adverse side effects.

Purpose To determine whether kidney sizes were changed after ureteral stents were instilled, and if so, what parameters were significant. Methods Parenchymal width (PW) of 98 patients with unilateral ureteral stents was measured from the coronal view of CT scans for both stented and unstented contralateral kidney. The mean PW and % change of mean PW were calculated before stenting and at the time of last stent change. Estimated glomerular filtrate rate (eGFR) was recorded as well. Results The mean duration of ureteral stent indwelled was 15.6 ± 10.2 (mean ± SD) months. The change of mean PW of stented kidneys and unstented contralateral kidneys was −16.9 ± 16.4 (mean ± SD)% and 3.6 ± 10.7%, respectively. eGFR before and at the time of the last stent change did not show significant difference (p = 0.294). Duration of ureteral stent indwelled was found to be inversely related to the % change of mean PW (Spearman's correlation coefficient = −0.291, p < 0.001). Conclusions For unilateral ureteral obstruction, kidney size was decreased over time in spite of indwelling ureteral stent. This finding can be overlooked by clinicians due to compensatory growth of contralateral kidney and resultant normal eGFR. PMID:28656136

To review the clinical features and pathophysiologic implications of remitting seronegative symmetrical synovitis with pitting edema (RS(3)PE) presenting in a unilateral manner. We identified and characterized an index case of RS(3)PE presenting in a unilateral pattern. We subsequently performed a systematic literature search to identify other reports of patients with unilateral RS(3)PE. The index case was a 76-year-old male with a prior history of right hemiparesis owing to a cerebrovascular accident 25 years prior, who developed a classic picture of RS(3)PE involving hand (metacarpophalageal and wrist joint) arthritis and dorsal pitting edema, accompanied by an elevated erythrocyte sedimentation rate, but only in the nonhemiparetic hand. The condition responded rapidly to low-dose prednisone. Our literature search identified 5 other cases of unilateral RS(3)PE, including 2 presented only in the Italian or German literature. Of the 5 cases, 2 were in patients with preexisting neurologic disease, in which the neurologically affected side was spared. One additional case initially presented as unilateral disease but rapidly progressed to bilaterality. Two cases presented in a fully unilateral manner despite no reported neurologic abnormalities on the unaffected sides. While RS(3)PE is almost always a symmetric disease of the upper extremities, it may rarely present in a unilateral fashion. The apparent ability of neuropathic changes to protect against the expression of RS(3)PE in an extremity suggests a role for neural and possibly other local factors in the genesis/modulation of the onset or maintenance of RS(3)PE.

Background Patients with unilateral sciatica have heightened responses to intradermal capsaicin compared to pain-free volunteers. No studies have investigated whether this pain model can screen for novel anti-neuropathic agents in patients with pre-existing neuropathic pain syndromes. Aim This study compared the effects of pregabalin (300 mg) and the tetracycline antibiotic and glial attenuator minocycline (400 mg) on capsaicin-induced spontaneous pain, flare, allodynia and hyperalgesia in patients with unilateral sciatica on both their affected and unaffected leg. Methods/Results Eighteen patients with unilateral sciatica completed this randomised, double-blind, placebo-controlled, three-way cross-over study. Participants received a 10 µg dose of capsaicin into the middle section of their calf on both their affected and unaffected leg, separated by an interval of 75 min. Capsaicin-induced spontaneous pain, flare, allodynia and hyperalgesia were recorded pre-injection and at 5, 20, 40, 60 and 90 min post-injection. Minocycline tended to reduce pre-capsaicin injection values of hyperalgesia in the affected leg by 28% (95% CI 0% to 56%). The area under the effect time curves for capsaicin-induced spontaneous pain, flare, allodynia and hyperalgesia were not affected by either treatment compared to placebo. Significant limb differences were observed for flare (AUC) (−38% in affected leg, 95% CI for difference −19% to −52%). Both hand dominance and sex were significant covariates of response to capsaicin. Conclusions It cannot be concluded that minocycline is unsuitable for further evaluation as an anti-neuropathic pain drug as pregabalin, our positive control, failed to reduce capsaicin-induced neuropathic pain. However, the anti-hyperalgesic effect of minocycline observed pre-capsaicin injection is promising pilot information to support ongoing research into glial-mediated treatments for neuropathic pain. The differences in flare response between limbs may

As life expectancy increases, it is expected that 60% of all cases of cancer will be detected in elderly patients in the next two decades. Cancer treatment for older persons is complicated by a number of factors, thus negatively affecting patients' quality of life. The purpose of this study is to investigate quality of life in elderly cancer patients undergoing chemotherapy. This study was descriptive and non-experimental. It was conducted in one large hospital in a major city of Northern Greece. The sample was convenience comprising 53 elderly cancer patients undergoing cycle 3 chemotherapy. The data was collected using the Functional Assessment of Cancer Therapy scale and included questions related to demographic and clinical characteristics. The majority of participants were men (n = 27, 50.9%) who were married (n = 32, 79.5%). Their mean age was 70.07 ± 3.60. Almost half of the sample (n = 30, 56.6%) had colon cancer. There was a statistical significant difference between men and women pertaining to physical wellbeing (p = 0.004) and overall quality of life (p < 0.001). When comparing each subscale with the patients' marital status it was found that there was a statistical difference with respect to social/family wellbeing (p = 0.029), functional wellbeing (p = 0.09) and overall quality of life (p < 0.001). Moreover, the type of cancer affected overall quality of life (p < 0.001) and social/family wellbeing (p = 0.029). These findings call attention to quality of life and its related factors in elderly cancer patients. It is highly recommended to envisage measures for improving quality of life in this group of cancer patients.

Brain natriuretic peptide (BNP) levels correlate with prognosis in patients with cardiac disease and may be useful in the risk stratification of cardiac patients undergoing noncardiac surgery (NCS). The objective of this study was to examine whether BNP levels predict perioperative events in cardiac patients undergoing NCS. Patients undergoing NCS with at least 1 of the following criteria were included: a clinical history of congestive heart failure (CHF), ejection fraction <40%, or severe aortic stenosis. All patients underwent echocardiography and measurement of BNP performed using the ADVIA-Centaur BNP assay (Bayer HealthCare). Clinical endpoints were death, myocardial infarction or pulmonary congestion requiring intravenous diuretics at 30 days of follow-up. Forty-four patients were entered into the study; 15 patients (34%) developed cardiac postoperative complications. The mean BNP level was 1,366 +/- 1,420 pg/ml in patients with events and 167 +/- 194 pg/ml in patients without events, indicating a highly significant difference (p < 0.001). The ROC area under the curve was 0.91 (95% CI 0.83-0.99) with an optimal cutoff of >165 pg/ml (100% sensitivity, 70% specificity). BNP levels may predict perioperative complications in cardiac patients undergoing NCS, and the measurement of BNP should be considered to assess the preoperative cardiac risk. (c) 2007 S.

Prosthetic joint infection (PJI) is a complication with serious repercussions and its main cause is Staphylococcus aureus. The purpose of this study is to determine whether decolonization of S.aureus carriers helps to reduce the incidence of PJI by S.aureus. An S.aureus screening test was performed on nasal carriers in patients undergoing knee or hip arthroplasty between January and December 2011. Patients with a positive test were treated with intranasal mupirocin and chlorhexidine soap 5 days. The incidence of PJI was compared with patients undergoing the same surgery between January and December 2010. A total of 393 joint replacements were performed in 391 patients from the control group, with 416 joint replacements being performed in the intervention group. Colonization study was performed in 382 patients (91.8%), of which 102 were positive (26.7%) and treated. There was 2 PJI due S.aureus compared with 9 in the control group (0.5% vs 2.3%, odds ratio [OR]: 0.2, 95% confidence interval [CI]: 0.4 to 2.3, P=.04). In our study, the detection of colonization and eradication of S.aureus carriers achieved a significant decrease in PJI due to S.aureus compared to a historical group.

Patients undergoing lobectomy are at significantly increased risk of lung injury. One-lung ventilation is the most commonly used technique to maintain ventilation and oxygenation during the operation. It is a challenge to choose an appropriate mechanical ventilation strategy to minimize the lung injury and other adverse clinical outcomes. In order to understand the available evidence, a systematic review was conducted including the following topics: (I) protective ventilation (PV); (II) mode of mechanical ventilation [e.g., volume controlled (VCV) versus pressure controlled (PCV)]; (III) use of therapeutic hypercapnia; (IV) use of alveolar recruitment (open-lung) strategy; (V) pre-and post-operative application of positive end expiratory pressure (PEEP); (VI) Inspired Oxygen concentration; (VII) Non-intubated thoracoscopic lobectomy; and (VIII) adjuvant pharmacologic options. The recommendations of class II are non-intubated thoracoscopic lobectomy may be an alternative to conventional one-lung ventilation in selected patients. The recommendations of class IIa are: (I) Therapeutic hypercapnia to maintain a partial pressure of carbon dioxide at 50-70 mmHg is reasonable for patients undergoing pulmonary lobectomy with one-lung ventilation; (II) PV with a tidal volume of 6 mL/kg and PEEP of 5 cmH 2 O are reasonable methods, based on current evidence; (III) alveolar recruitment [open lung ventilation (OLV)] may be beneficial in patients undergoing lobectomy with one-lung ventilation; (IV) PCV is recommended over VCV for patients undergoing lung resection; (V) pre- and post-operative CPAP can improve short-term oxygenation in patients undergoing lobectomy with one-lung ventilation; (VI) controlled mechanical ventilation with I:E ratio of 1:1 is reasonable in patients undergoing one-lung ventilation; (VII) use of lowest inspired oxygen concentration to maintain satisfactory arterial oxygen saturation is reasonable based on physiologic principles; (VIII) Adjuvant drugs

We investigated the lateralization of brain activity pattern during performance of unilateral movement in drug-naïve Parkinson's disease (PD) patients with only right hemiparkinsonian symptoms. Functional MRI was obtained when the subjects performed strictly unilateral right hand movement. A laterality index was calculated to examine the lateralization. Patients had decreased activity in the left putamen and left supplementary motor area, but had increased activity in the right primary motor cortex, right premotor cortex, left postcentral gyrus, and bilateral cerebellum. The laterality index was significantly decreased in PD patients compared with controls (0.41 ± 0.14 vs. 0.84 ± 0.09). The connectivity from the left putamen to cortical motor regions and cerebellum was decreased, while the interactions between the cortical motor regions, cerebellum, and right putamen were increased. Our study demonstrates that in early PD, the lateralization of brain activity during unilateral movement is significantly reduced. The dysfunction of the striatum-cortical circuit, decreased transcallosal inhibition, and compensatory efforts from cortical motor regions, cerebellum, and the less affected striatum are likely reasons contributing to the reduced motor lateralization. The disruption of the lateralized brain activity pattern might be a reason underlying some motor deficits in PD, like mirror movements or impaired bilateral motor coordination. © 2015 Wiley Periodicals, Inc.

To compare the effects of rTMS combined with sensory cueing, rTMS alone, and conventional rehabilitation on unilateral neglect, hemiplegic arm functions and performance of activities of daily living. A single-blinded randomized controlled trial. A convalescent hospital. Sixty inpatients with left unilateral neglect after stroke. Patients were randomly assigned to three groups: rTMS combined with sensory cueing, rTMS, and conventional rehabilitation alone. rTMS at 1 Hz was applied over P5 of the contralesional hemisphere while vibration cueing was emitted using a wristwatch device on the hemiplegic arm, five days per week for two weeks. The first two groups received the same dosage of conventional rehabilitation on top of their experimental interventions. Blinded assessments were administered at baseline, 2 weeks postintervention, and 6 weeks follow-up. Neglect and arm motor performance. Both rTMS combined with sensory cueing (99.6±33.0) and rTMS alone (88.2±28.7) significantly reduced unilateral neglect than conventional rehabilitation (72.7±33.1) when measured using the conventional subtests of the Behavioural Inattention Test, but the combination was better than rTMS alone. Hemiplegic arm functions and activities of daily living improved in all patients across the three groups but no significant differences were found between the groups. The combination of inhibitory P5-rTMS with sensory cueing was better than either rTMS or conventional rehabilitation alone in producing a stronger and long-lasting improvement in unilateral neglect, but the improvement was not associated with improved arm function or independence in activities of daily living.

Introduction: Tuberculum Sellae Meningioma is one of the most challenging surgeries among neurosurgeons. Many approaches have been established in the effort of removing the tumor and some of them are supported by an advanced neurosurgical technology. In this study, we aim to compare the efficacy of the two most common approaches, the pterional and the unilateral frontal. Materials and Methods: This was a restrospective study that aimed to observe the efficacy of the two most common approaches used in our center, the pterional and the unilateral frontal, in resecting the tuberculum sellae meningioma, which was held in Dr. Hasan Sadikin General Hospital, Bandung, from July 2007-July 2010. Twenty patients were enrolled with half of them operated by the pterional approach and the rest by unilateral frontal approach. We evaluated six parameters: tumor size, degree of tumor removal, surgery duration, post-operative cerebral edema, patients' outcome, and length of stay, which were evaluated to take measure of the efficacy of each procedure. Results: We found that the pterional approach gave more advantages than the unilateral frontal. Total tumor removal, especially in tumor size ≥ 3 cm was achieved in a greater number of subjects in the pterional (P<0.023). Other advantages of the pterional compared to the unilateral frontal were a shorter surgical duration (P=0.024), shorter length of stay (P=0.009) and less frequency of post-operative cerebral edema incidence (P=0.023). Conclusion: According to our facilities and conditions, it seems that the pterional approach have more advantages than the unilateral frontal approach in tuberculum sellae meningioma surgery.

Background: Hydrocephalus caused by unilateral foramen of Monro (FM) obstruction has been referred to in literature by many different terminologies. Precise terminology describing hydrocephalus confined to just one lateral ventricle has a very important prognostic value and determines whether or not the patient can be shunt free after an endoscopic procedure. Methods: Aiming to define the best term for unilateral FM obstruction, 19 terms were employed on PubMed database (http://www.ncbi.nlm.nih.gov/pubmed) as quoted phrases. Results: A total of 194 articles were found. Four patterns of hydrocephalus were discriminated as a result of our research term query and were divided by types for didactic purpose. Type A - partial dilation of the lateral ventricle; Type B - pure unilateral obstruction of the FM; Type C - previously shunted patients with secondary obstruction of the FM; and Type D - asymmetric lateral ventricles with patent FM. Conclusion: In unilateral FM obstruction hydrocephalus, an in-depth review on terminology application is critical to avoid mistakes that may compromise comparisons among different series. This terminology review suggests that Type B hydrocephalus, i.e., the hydrocephalus confined to just one lateral ventricle with no other sites of cerebrospinal fluid circulation blockage, are best described by the terms unilateral hydrocephalus (UH) and monoventricular hydrocephalus, the first being by far the most popular. Type A hydrocephalus is best represented in the literature by the terms uniloculated hydrocephalus and loculated ventricle; Type C hydrocephalus by the terms isolated lateral ventricle and isolated UH; and Type D hydrocephalus by the term asymmetric hydrocephalus.

This work discusses the production and management of liquid radioactive wastes as excretas from patients undergoing therapy procedures with 131I radiopharmaceuticals in Spain. The activity in the sewage has been estimated with and without waste radioactive decay tanks. Two common therapy procedures have been considered, the thyroid cancer (4.14 GBq administered per treatment), and the hyperthyroidism (414 MBq administered per treatment). The calculations were based on measurements of external exposure around the 244 hyperthyroidism patients and 23 thyroid cancer patients. The estimated direct activity discharged to the sewage for two thyroid carcinomas and three hyperthyroidisms was 14.57 GBq and 1.27 GBq, respectively, per week; the annual doses received by the most exposed individual (sewage worker) were 164 microSv and 13 microSv, respectively. General equations to calculate the activity as a function of the number of patient treated each week were also obtained.

This study evaluates the effect of unilateral conductive hearing loss secondary to aural atresia on elementary school children's academic performance. Case control survey and review of audiometric data. One hundred thirty-two surveys were mailed to families of children with aural atresia, and 48 surveys were sent to families of children with unilateral sensorineural hearing loss (SNHL) to identify rates of grade retention, use of any resource, and behavioral problems. Audiometric data of the cohort were tabulated. Of the 40 atresia patients, none repeated a grade, but 65% needed some resources: 12.5% currently use a hearing aid, 32.5% use(d) a frequency-modulated system in school, 47.5% had an Individualized Education Plan, and 45% utilized speech therapy. Compared to the unilateral SNHL group and a cohort of children with unilateral SNHL in an earlier study, children with unilateral atresia were less likely to repeat a grade. Children in both unilateral atresia and SNHL groups were more likely to utilize some resource in the academic setting compared to the unilateral SNHL children in the prior study. Unilateral conductive hearing loss due to aural atresia has an impact on academic performance in children, although not as profound when compared to children with unilateral SNHL. The majority of these children with unilateral atresia utilize resources in the school setting. Parents, educators, and health care professionals should be aware of the impact of unilateral conductive hearing loss and offer appropriate habilitative services.

In this study, we investigated the horizontal visual search ability and pattern of horizontal visual search in a large space performed by patients with unilateral spatial neglect (USN). Subjects included nine patients with right hemisphere damage caused by cerebrovascular disease showing left USN, nine patients with right hemisphere damage but no USN, and six healthy individuals with no history of brain damage who were age-matched to the groups with brain right hemisphere damage. The number of visual search tasks accomplished was recorded in the first experiment. Neck rotation angle was continuously measured during the task and quantitative data of the measurements were collected. There was a strong correlation between the number of visual search tasks accomplished and the total Behavioral Inattention Test Conventional Subtest (BITC) score in subjects with right hemisphere damage. In both USN and control groups, the head position during the visual search task showed a balanced bell-shaped distribution from the central point on the field to the left and right sides. Our results indicate that compensatory strategies, including cervical rotation, may improve visual search capability and achieve balance on the neglected side. Copyright © 2012 Elsevier Ltd.

Hemodialysis (HD) patients have been increasing recently. Some rheumatoid arthritis (RA) patients need hemodialysis (HD), though the proportion is not high. At present, such patients are almost treated with corticosteroids and/or nonsteroidal anti-inflammatory drugs alone, even if they have a high disease activity that would require disease-modifying anti-rheumatic drug (DMARD) therapy, partly because the safety of DMARDs in RA patients with end-stage renal disease has not been confirmed. Their joint destruction would be inevitable and lead to impaired activities of daily living. As there are no guidelines for the use of DMARDs in HD patients, here I reviewed the previous reports about the treatment of DMARDs including biologics for patients with RA undergoing HD.

The recently developed TOMAX-procedure restores unilateral genital sensation, improving sexual health in men with a low spinal lesion (LSL). It connects one dorsal nerve of the penis (DNP) to the intact ipsilateral ilioinguinal nerve. We proposed bilateral neurotization for full sensation of the glans but this entails cutting both DNPs, risking patients' erection/ejaculation ability. The objective was to select patients for a bilateral TOMAX-procedure by measuring remaining DNP function, and perform the first bilateral cases. In 30 LSL patients with no penile- but normal groin sensation selected for a unilateral TOMAX-procedure the integrity of the sacral-reflex-arc and DNP function was tested pre-operatively using bilateral needle electromyography (EMG)-bulbocavernosus reflex (BCR) measurements, and an interview about reflex erections (RE) ability. In 13 spina bifida- and 17 spinal cord injury patients [median age 29.5 years (range 13-59 years), spinal lesion T12 (incomplete) to sacral], seven (23%) patients reported RE, four (57%) with intact BCR, and of nine (30%) patients with intact BCR, four reported RE (44%). Even patients with a LSL and no penile sensation can have signs of remaining DNP function, but cutting both DNPs to restore full glans sensation in a bilateral TOMAX-procedure might interfere with their RE/ejaculation. To avoid this risk, we propose a selecting-protocol for a unilateral- or bilateral procedure using RE and BCR measurements. Using this protocol, three patients were bilaterally operated with promising preliminary results. Full sensation of the glans could lead to further improvement in sexual function. © 2014 Wiley Periodicals, Inc.

Reduction of cognitive function is a possible side effect after cardiac surgery using cardiopulmonary bypass. We investigated the cerebroprotective effect of piracetam on cognitive performance in patients undergoing coronary artery bypass surgery under cardiopulmonary bypass. Patients scheduled for elective, primary and isolated coronary bypass surgery were randomised either to piracetam or placebo group. The study was performed in a double blind fashion. Patients received either 12 g piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on the third postoperative day. To assess the overall cognitive function and the degree of cognitive decline across all tests after surgery we combined the six test-scores by principal component analysis. A total number of 120 patients were enrolled into the study. Preoperative overall cognitive function were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed a deterioration of cognitive function in both groups (placebo-pre: -0.06+/-0.99 vs placebo-post: -1.38+/-1.11; p<0.0005 and piracetam-pre: 0.06+/-1.02 vs piracetam-post: -0.65+/-0.93; p<0.0005). However, the piracetam patients performed significantly better compared to the placebo patients after the operation and had a less decline of overall cognitive function (p<0.0005). Piracetam has a cerebroprotective effect in patients undergoing coronary artery bypass surgery with the use of cardiopulmonary bypass. It reduces an early postoperative substantial decline of neuropsychological abilities.

Unilateral visuospatial deficits have been observed in children with brain damage. While the effectiveness of prism adaptation for treating unilateral neglect in adult stroke patients has been demonstrated previously, the usefulness of prism adaptation in a pediatric population is still unknown. The present study aims at evaluating the feasibility of prism adaptation in children with unilateral brain lesion and comparing the validity of a game procedure designed for child-friendly paediatric intervention, with the ecological task used for prism adaptation in adult patients. Twenty-one children with unilateral brain lesion randomly were assigned to a prism group wearing prismatic glasses, or a control group wearing neutral glasses during a bimanual task intervention. All children performed two different bimanual tasks on randomly assigned consecutive days: ecological tasks or game tasks. The efficacy of prism adaptation was measured by assessing its after-effects with visual open loop pointing (visuoproprioceptive test) and subjective straight-ahead pointing (proprioceptive test). Game tasks and ecological tasks produced similar after-effects. Prismatic glasses elicited a significant shift of visuospatial coordinates which was not observed in the control group. Prism adaptation performed with game tasks seems an effective procedure to obtain after-effects in children with unilateral brain lesion. The usefulness of repetitive prism adaptation sessions as a therapeutic intervention in children with visuospatial deficits and/or neglect, should be investigated in future studies.

To assess measurement errors of a novel technique for the three-dimensional determination of the degree of facial symmetry in patients suffering from unilateral cleft lip and palate malformations. Technical report, reliability study. Cleft Lip and Palate Center of the University of Erlangen-Nuremberg, Erlangen, Germany. The three-dimensional facial surface data of five 10-year-old unilateral cleft lip and palate patients were subjected to the analysis. Distances, angles, surface areas, and volumes were assessed twice. Calculations were made for method error, intraclass correlation coefficient, and repeatability of the measurements of distances, angles, surface areas, and volumes. The method errors were less than 1 mm for distances and less than 1.5 degrees for angles. The intraclass correlation coefficients showed values greater than .90 for all parameters. The repeatability values were comparable for cleft and noncleft sides. The small method errors, high intraclass correlation coefficients, and comparable repeatability values for cleft and noncleft sides reveal that the new technique is appropriate for clinical use.

This study was conducted to evaluate the effect of royal jelly on oral mucositis in patients undergoing radiotherapy and chemotherapy. The study population consisted of 103 patients undergoing radiotherapy and chemotherapy. Oral mucositis was graded according to the World Health Organization criteria, and patients were divided into 2 groups. All patients received mouthwash therapy with benzydamine hydrochloride and nystatin rinses. In addition, patients in the experimental group received royal jelly. The mean resolution time of oral mucositis in the royal jelly group was significantly shorter than that of the control group. As a result, the study results demonstrate that royal jelly administrated by a certain procedure improved the signs and symptoms of oral mucositis and markedly shortened its healing time.

The outcomes of 2 patients with cochlear implants (CIs) who underwent adenotonsillectomy (AT) with inadvertent use of monopolar cautery are presented. The safety data regarding monopolar cautery use in CI recipients is also reviewed. This is a retrospective case series of 2 CI recipients that underwent AT with monopolar cautery and literature review of electrocautery safety in the setting of CI. Two patients with CIs underwent AT with use of monopolar cautery inadvertently by surgeons that do not routinely perform cochlear implants as part of his or her clinical practice. Patient 1 was a 9-year-old female who had AT for obstructive sleep apnea (OSA) after undergoing unilateral CI for profound congenital sensorineural hearing loss (SNHL) 8 years ago. Patient 2 was a 7-year-old female who underwent AT for OSA 4 months after undergoing unilateral CI for congenital SNHL. Both patients had no immediate signs of complications with their CI use postoperatively. Both patients demonstrated unchanged postoperative neural response telemetry and behavioral audiometric testing. Patient 1 continues to have no CI-related complications 3.5 years after the procedure. Patient 2 has been followed for at least 3 months by audiometric testing and 10 months by otolaryngologist with no CI-related complications. Although animal and cadaveric studies suggest that monopolar cautery may be safely used in patients with cochlear implants, there have been no in vivo human studies that have evaluated the risk to the patient or implant. This is a report of a small, unintended experience with 2 patients, both of whom exhibit no complications or changes to CI function thus far. © The Author(s) 2016.

A Comparative Study to Evaluate the Functional Effect of Unilateral Uvuloplasty after Primary Palatoplasty

PubMed Central

Olivencia-Flores, Claudia; Gavino-Gutierrez, Arquímedes M.; Caceres-Nano, Evelyn; Cotrina-Rabanal, Omar

2015-01-01

Background: The conventional method for uvular repair suturing the 2 hemi-uvulas of the palatal cleft together in the midline does not allow us to obtain a proper anatomical repair. In our hands, the midline straight closure frequently causes retraction of the uvular tissues with the consequent abnormal appearance of the uvula. We described before a method for uvular repair in patients with cleft palate. The technique consists in preserving one of the hemi-uvulas, which is moved to the midline to form the definitive uvula. The purpose of this study was to evaluate the functional effects of the unilateral uvuloplasty for uvular repair in a group of patients with bilateral cleft palate. Methods: This is a retrospective, single-blinded cohort study between 2 groups of 90 patients with bilateral cleft palate who were operated on using the conventional and unilateral uvuloplasty methods of uvular repair from 2000 to 2009. Data collection was accomplished by physical examination to evaluate the presence of postoperative fistulas and hypernasal speech determined at 6 months to 5 years after surgery. In addition, postoperative dimensions of the velopharynx were measured by a single-blind examiner using a computed tomography scan. Results: Our comparative study found statistically significant differences between the 2 groups in favor of the unilateral uvuloplasty group. Conclusions: We observed that the use of unilateral uvuloplasty for uvular reconstruction reduces the velopharyngeal space and the frequency of hypernasality in patients with bilateral cleft palate.

The objective of this study was to determine the levels of patient-satisfaction on facial and dental appearance compared with clinician ratings. Participants included 61 patients with repaired unilateral cleft lip and palate (UCLP), aged 14-25 years. Raters comprised three cleft team clinicians. A Likert scale was used to assess the levels of satisfaction of the patients themselves and the clinicians. The results revealed that the patients were moderately satisfied with their appearance. Nose was the least satisfactory feature, followed by lip appearance. When compared to the clinician ratings, the patients were less satisfied with their own nose and lip, but more satisfied with teeth. Concerning age, self-assessment did not differ between adolescents and young adults. Females were less likely to be satisfied compared to males, but the difference was not statistically significant. In conclusion, patients with repaired UCLP were moderately satisfied with their facial and dental appearance. Clinician- and patient-opinions were different in some aspects. This study highlights the importance of patient satisfaction as a meaningful treatment outcome assessment, which could lead to an improvement in cleft care to meet the patient expectations.

Visuo-spatial neglect and vestibular disorders have common clinical findings and involve the same cortical areas. We questioned (1) whether visuo-spatial hemineglect is not only a disorder of spatial attention but may also reflect a disorder of higher cortical vestibular function and (2) whether a vestibular tone imbalance due to an acute peripheral dysfunction can also cause symptoms of neglect or extinction. Therefore, patients with an acute unilateral peripheral vestibular failure (VF) were tested for symptoms of hemineglect. Twenty-eight patients with acute VF were assessed for signs of vestibular deficits and spatial neglect using clinical measures and various common standardized paper-pencil tests. Neglect severity was evaluated further with the Center of Cancellation method. Pathological neglect test scores were correlated with the degree of vestibular dysfunction determined by the subjective visual vertical and caloric testing. Three patients showed isolated pathological scores in one or the other neglect test, either ipsilesionally or contralesionally to the VF. None of the patients fulfilled the diagnostic criteria of spatial hemineglect or extinction. A vestibular tone imbalance due to unilateral failure of the vestibular endorgan does not cause spatial hemineglect, but evidence indicates it causes mild attentional deficits in both visual hemifields.

Objective To develop a reliable and easy-to-use method to assess the nasolabial appearance of 18-year-old patients with unilateral cleft lip and palate (CLP). Design Retrospective analysis of nasolabial aesthetics using a 5-point ordinal scale and newly developed photographic reference scale: the Cleft Aesthetic Rating Scale (CARS). Three cleft surgeons and 20 medical students scored the nasolabial appearance on standardized frontal photographs. Setting VU University Medical Center, Amsterdam. Patients Inclusion criteria: 18-year-old patients, unilateral cleft lip and palate, available photograph of the frontal view. history of facial trauma, congenital syndromes affecting facial appearance. Eighty photographs were available for scoring. Main Outcome Measures The interobserver and intraobserver reliability of the CARS for 18-year-old patients when used by cleft surgeons and medical students. Results The interobserver reliability for the nose and lip together was 0.64 for the cleft surgeons and 0.61 for the medical students. There was an intraobserver reliability of 0.75 and 0.78 from the surgeons and students, respectively, on the nose and lip together. No significant difference was found between the cleft surgeons and medical students in the way they scored the nose ( P = 0.22) and lip ( P = 0.72). Conclusions The Cleft Aesthetic Rating Scale for 18-year-old patients has a substantial overall estimated reliability when the average score is taken from three or more cleft surgeons or medical students assessing the nasolabial aesthetics of CLP patients.

We identified two female siblings, derived from healthy first cousin parents, with congenital unilateral cerebral ventriculomegaly detected prenatally. Patient 1 underwent ventriculoperitoneal shunt operation at 1 week old, while Patient 2 was followed without surgical intervention. Both patients presented with mild developmental delay and hemiparesis contralateral to the involved hemisphere. Focal seizures were observed in Patient 1, whose neuroimaging revealed posterior insular polymicrogyria in the normal sized ventricle hemisphere and retrocerebellar cyst. Both siblings displayed near absence of white matter with marked thinning of the overlying cortex in the affected hemisphere and very thin corpus callosum. Investigations revealed no other system involvement and karyotyping was normal. Normal TORCH screening in subsequent pregnancies, normal parental coagulation profile and undetectable maternal autoantibodies suggested against the possible role of extrinsic factors as an etiological factor for unilateral ventriculomegaly. Parents had normal brain imaging findings. We suggest delineation of a distinct developmental brain defect, most likely of autosomal recessive inheritance. PMID:19610102

To investigate the outcomes of percutaneous unilateral metallic stent placement in patients with a malignant obstruction of the biliary hila and a contralateral portal vein steno-occlusion. Sixty patients with a malignant hilar obstruction and unilobar portal vein steno-occlusion caused by tumor invasion or preoperative portal vein embolization were enrolled in this retrospective study from October 2010 to October 2013. All patients were treated with percutaneous placement of a biliary metallic stent, including expanded polytetrafluoroethylene (ePTFE)-covered stents in 27 patients and uncovered stents in 33 patients. A total of 70 stents were successfully placed in 60 patients. Procedural-related minor complications, including self-limiting hemobilia (n = 2) and cholangitis (n = 4) occurred in six (10%) patients. Acute cholecystitis occurred in two patients. Successful internal drainage was achieved in 54 (90%) of the 60 patients. According to a Kaplan-Meier analysis, median survival time was 210 days (95% confidence interval [CI], 135-284 days), and median stent patency time was 133 days (95% CI, 94-171 days). No significant difference in stent patency was observed between covered and uncovered stents (p = 0.646). Stent dysfunction occurred in 16 (29.6%) of 54 patients after a mean of 159 days (range, 65-321 days). Unilateral placement of ePTFE-covered and uncovered stents in the hepatic lobe with a patent portal vein is a safe and effective method for palliative treatment of patients with a contralateral portal vein steno-occlusion caused by an advanced hilar malignancy or portal vein embolization. No significant difference in stent patency was detected between covered and uncovered metallic stents.

We aimed to determine the radiation doses delivered to patients undergoing general examinations using computed or digital radiography systems in Turkey. Radiographs of 20 patients undergoing posteroanterior chest X-ray and of 20 patients undergoing anteroposterior kidney-ureter-bladder radiography were evaluated in five X-ray rooms at four local hospitals in the Ankara region. Currently, almost all radiology departments in Turkey have switched from conventional radiography systems to computed radiography or digital radiography systems. Patient dose was measured for both systems. The results were compared with published diagnostic reference levels (DRLs) from the European Union and International Atomic Energy Agency. The average entrance surface doses (ESDs) for chest examinations exceeded established international DRLs at two of the X-ray rooms in a hospital with computed radiography. All of the other ESD measurements were approximately equal to or below the DRLs for both examinations in all of the remaining hospitals. Improper adjustment of the exposure parameters, uncalibrated automatic exposure control systems, and failure of the technologists to choose exposure parameters properly were problems we noticed during the study. This study is an initial attempt at establishing local DRL values for digital radiography systems, and will provide a benchmark so that the authorities can establish reference dose levels for diagnostic radiology in Turkey.

To systematically analyze published randomized trials on the effectiveness of preoperative prophylactic antibiotics in patients undergoing breast surgical procedures. Trials on the effectiveness of preoperative prophylactic antibiotics in patients undergoing breast surgery were selected and analyzed to generate summated data (expressed as risk ratio [RR]) by using RevMan 5.0. Nine randomized controlled trials encompassing 3720 patients undergoing breast surgery were retrieved from the electronic databases. The antibiotics group comprised a total of 1857 patients and non-antibiotics group, 1863 patients. There was no heterogeneity [χ(2) = 7.61, d.f. = 7, p < 0.37; I(2) = 8%] amongst trials. Therefore, in the fixed-effects model (RR, 0.64; 95% CI, 0.50-0.83; z = 3.48; p < 0.0005), the use of preoperative prophylactic antibiotics in patients undergoing breast surgical procedures was statistically significant in reducing the incidence of surgical site infection (SSI). Furthermore, in the fixed-effects model (RR, 1.30; 95% CI, 0.89-1.90; z = 1.37; p < 0.17), adverse reactions secondary to the use of prophylactic antibiotics was not statistically significant between the two groups. Preoperative prophylactic antibiotics significantly reduce the risk of SSI after breast surgical procedures. The risk of adverse reactions from prophylactic antibiotic administration is not significant in these patients. Therefore, preoperative prophylactic antibiotics in breast surgery patients may be routinely administered. Further research is required, however, on risk stratification for SSI, timing and duration of prophylaxis, and the need for prophylaxis in patients undergoing breast reconstruction versus no reconstruction. © 2012 Wiley Periodicals, Inc.

A male child suffering from generalized tonic clonic epilepsy, on treatment with valproate, developed fulminant hepatic failure, hyperammonemia and encephalopathy due to drug toxicity. The most extraordinary feature was his MRI (FLAIR image) of brain which showed unilateral hyperintensities in right putamen and caudate nucleus. The patient recovered on withdrawal of valproate with mild residual left sided athetotic movements during remission. Repeat investigation confirmed an improved MRI imaging and normalised blood ammonia levels. The case report is unique because of unilateral involvement of basal ganglia due to valproate-induced encephalopathy.

It has been previously demonstrated that T lymphocytes may be involved in the development of hypertension and microvascular remodeling, and that circulating T effector lymphocytes may be increased in hypertension. In particular, Th1 and Th 17 lymphocytes may contribute to the progression of hypertension and microvascular damage while T-regulatory (Treg) lymphocytes seem to be protective in this regard. However, no data is available about patients with severe obesity, in which pronounced microvascular alterations were observed. We have investigated 32 severely obese patients undergoing bariatric surgery, as well as 24 normotensive lean subjects and 12 hypertensive lean subjects undergoing an elective surgical intervention. A peripheral blood sample was obtained before surgery for assessment of CD4+ T lymphocyte subpopulations. Lymphocyte phenotype was evaluated by flow cytometry in order to assess T-effector and Treg lymphocytes. A marked reduction of several Treg subpopulations was observed in obese patients compared with controls, together with an increased in CD4+ effector memory T-effector cells. In severely obese patients, Treg lymphocytes are clearly reduced and CD4+ effector memory cells are increased. It may be hypothesized that they might contribute to the development of marked microvascular alterations previously observed in these patients.

The objective of the present study is to evaluate the effect of hybrid cochlear implantation (hCI) on quality of life (QoL), quality of hearing (QoH), and working performance in adult patients, and to compare the long-term results of patients with hCI to those of patients with conventional unilateral cochlear implantation (CI), bilateral CI, and single-sided deafness (SSD) with CI. Sound localization accuracy and speech-in-noise test were also compared between these groups. Eight patients with high-frequency sensorineural hearing loss of unknown etiology were selected in the study. Patients with hCI had better long-term speech perception in noise than uni- or bilateral CI patients, but the difference was not statistically significant. The sound localization accuracy was equal in the hCI, bilateral CI, and SSD patients. QoH was statistically significantly better in bilateral CI patients than in the others. In hCI patients, residual hearing was preserved in all patients after the surgery. During the 3.6-year follow-up, the mean hearing threshold at 125-500 Hz decreased on average by 15 dB HL in the implanted ear. QoL and working performance improved significantly in all CI patients. Hearing outcomes with hCI are comparable to the results of bilateral CI or CI with SSD, but hearing in noise and sound localization are statistically significantly better than with unilateral CI. Interestingly, the impact of CI on QoL, QoH, and working performance was similar in all groups.

Context Myocardial perfusion imaging (MPI) is the single medical test with the highest radiation burden to the US population. While many patients undergoing MPI receive repeat MPI testing, or additional procedures involving ionizing radiation, no data are available characterizing their total longitudinal radiation burden and relating radiation burden with reasons for testing. Objective To characterize procedure counts, cumulative estimated effective doses of radiation, and clinical indications, for patients undergoing MPI. Design, Setting, Patients Retrospective cohort study evaluating, for 1097 consecutive patients undergoing index MPI during the first 100 days of 2006 at Columbia University Medical Center, all preceding medical imaging procedures involving ionizing radiation undergone beginning October 1988, and all subsequent procedures through June 2008, at that center. Main Outcome Measures Cumulative estimated effective dose of radiation, number of procedures involving radiation, and indications for testing. Results Patients underwent a median (interquartile range, mean) of 15 (6–32, 23.9) procedures involving radiation exposure; 4 (2–8, 6.5) were high-dose (≥3 mSv, i.e. one year's background radiation), including 1 (1–2, 1.8) MPI studies per patient. 31% of patients received cumulative estimated effective dose from all medical sources >100mSv. Multiple MPIs were performed in 39% of patients, for whom cumulative estimated effective dose was 121 (81–189, 149) mSv. Men and whites had higher cumulative estimated effective doses, and there was a trend towards men being more likely to undergo multiple MPIs than women (40.8% vs. 36.6%, Odds ratio 1.29, 95% confidence interval 0.98–1.69). Over 80% of initial and 90% of repeat MPI exams were performed in patients with known cardiac disease or symptoms consistent with it. Conclusion In this institution, multiple testing with MPI was very common, and in many patients associated with very high cumulative

To evaluate the subjective hearing handicap in patients with unilateral deafness after acoustic neuroma surgery and the effect of the Bone-anchored Hearing Aid (BAHA) on test band. Fifty-nine consecutive patients with unilateral deafness after translabyrintine removal of an acoustic neuroma, treated in Denmark in 2001 and 2002, were included. The patients were asked to complete a questionnaire, which addressed the subjective handicap of unilateral deafness; 90% responded. These patients were invited to test the BAHA on test band, and the subjective and objective effects were recorded. Eighty percent of the patients thought that they had a subjective hearing handicap of some significance. However, only 50% accepted the invitation to test the BAHA. The overall subjective effect was positive, and a significant improvement in speech discrimination in noise with the BAHA was demonstrated. After the test, however, only about 50%, that is, 25% of all patients wished implantation for BAHA treatment. This study shows that unilateral deafness after acoustic neuroma surgery is thought as a handicap in most of the patients and confirms that treatment with the BAHA has positive subjective effects and improves speech discrimination in noise. However, only 25% of the patients wished implantation for BAHA treatment. The implications of these findings are discussed. Data from centers that perform simultaneous acoustic neuroma surgery and implantation for BAHA are necessary for firm conclusions.

Patients often resort to religious and spiritual activities to cope with physical and mental challenges. The effect of spiritual coping on overall health, adaptation and health-related quality of life among patients undergoing haemodialysis (HD) is well documented. Thus, it is essential to establish a valid and reliable instrument that can assess both the religious and non-religious coping methods in patients undergoing HD. This study aimed to assess the validity and reliability of the Spiritual Coping Strategies Scale Arabic version (SCS-A) in Saudi patients undergoing HD. A convenience sample of 60 Saudi patients undergoing HD was recruited for this descriptive, cross-sectional study. Data were collected between May and June 2015. Forward-backward translation was used to formulate the SCS-A. The SCS-A, Muslim Religiosity Scale and the Quality of Life Index Dialysis Version III were used to procure the data. Internal consistency reliability, stability reliability, factor analysis and construct validity tests were performed. Analyses were set at the 0.05 level of significance. The SCS-A showed an acceptable internal consistency and strong stability reliability over time. The EFA produced two factors (non-religious and religious coping). Satisfactory construct validity was established by the convergent and divergent validity and known-groups method. The SCS-A is a reliable and valid tool that can be used to measure the religious and non-religious coping strategies of patients undergoing HD in Saudi Arabia and other Muslim and Arabic-speaking countries. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Background and purpose We evaluated two methods to identify mesial temporal sclerosis (MTS): visual inspection by experienced epilepsy neuroradiologists based on structural magnetic resonance imaging sequences and automated hippocampal volumetry provided by a processing pipeline based on the FMRIB Software Library. Methods This retrospective study included patients from the epilepsy monitoring unit database of our institution. All patients underwent brain magnetic resonance imaging in 1.5T and 3T scanners with protocols that included thin coronal T2, T1 and fluid-attenuated inversion recovery and isometric T1 acquisitions. Two neuroradiologists with experience in epilepsy and blinded to clinical data evaluated magnetic resonance images for the diagnosis of MTS. The diagnosis of MTS based on an automated method included the calculation of a volumetric asymmetry index between the two hippocampi of each patient and a threshold value to define the presence of MTS obtained through statistical tests (receiver operating characteristics curve). Hippocampi were segmented for volumetric quantification using the FIRST tool and fslstats from the FMRIB Software Library. Results The final cohort included 19 patients with unilateral MTS (14 left side): 14 women and a mean age of 43.4 ± 10.4 years. Neuroradiologists had a sensitivity of 100% and specificity of 73.3% to detect MTS (gold standard, k = 0.755). Automated hippocampal volumetry had a sensitivity of 84.2% and specificity of 86.7% (k = 0.704). Combined, these methods had a sensitivity of 84.2% and a specificity of 100% (k = 0.825). Conclusions Automated volumetry of the hippocampus could play an important role in temporal lobe epilepsy evaluation, namely on confirmation of unilateral MTS diagnosis in patients with radiological suggestive findings.

OBJECTIVE Bilateral symptoms have been reported in 8%-35% of patients with sacroiliac (SI) joint dysfunction. Stabilization of a single SI joint may significantly alter the stresses on the contralateral SI joint. If the contralateral SI joint stresses are significantly increased, degeneration may occur; alternatively, if the stresses are significantly reduced, bilateral stabilization may be unnecessary for patients with bilateral symptoms. The biomechanical effects of 1) unilateral stabilization on the contralateral SI joint and 2) bilateral stabilization on both SI joints are currently unknown. The objectives of this study were to characterize bilateral SI joint range of motion (ROM) and evaluate and compare the biomechanical effects of unilateral and bilateral implant placement for SI joint fusion. METHODS A lumbopelvic model (L5-pelvis) was used to test the ROM of both SI joints in 8 cadavers. A single-leg stance setup was used to load the lumbar spine and measure the ROM of each SI joint in flexion-extension, lateral bending, and axial rotation. Both joints were tested 1) while intact, 2) after unilateral stabilization, and 3) after bilateral stabilization. Stabilization consisted of lateral transiliac placement of 3 triangular titanium plasma-sprayed (TPS) implants. RESULTS Intact testing showed that during single-leg stance the contralateral SI joint had less ROM in flexion-extension (27%), lateral bending (32%), and axial rotation (69%) than the loaded joint. Unilateral stabilization resulted in significant reduction of flexion-extension ROM (46%) on the treated side; no significant ROM changes were observed for the nontreated side. Bilateral stabilization resulted in significant reduction of flexion-extension ROM of the primary (45%) and secondary (75%) SI joints. CONCLUSIONS This study demonstrated that during single-leg loading the ROMs for the stance (loaded) and swing (unloaded) SI joints are significantly different. Unilateral stabilization for SI

A 27-year-old woman with a history of nyctalopia and constriction of visual field of the right eye. The ophthalmological examination showed a visual field and electroretinogram that were compatible with unilateral retinitis pigmentosa (RP). After a one year follow-up, the unilateral condition remained. Unilateral retinitis pigmentosa is a rare condition, with a frequency between 0.2%-5% of the RP. It mainly affects women and older age groups than bilateral RP. For a definitive diagnosis, it is necessary to have a funduscopy and electroretinogram (ERG) altered unilaterally, and exclude infectious, inflammatory, and vascular causes.

Harato, Kengo; Yoshida, Hiroki; Otani, Toshiro

2013-08-01

Unilateral total knee arthroplasty (TKA) would produce asymmetric changes of lower extremity in patients with bilateral varus deformity. Our purpose was to investigate whether asymmetry of the leg alignment would affect trunk bending in the coronal plane after unilateral TKA. Twenty patients (mean 76 years old) with bilateral end-stage knee osteoarthritis (OA) participated. Spine images during relaxed standing were obtained on pre- and postoperative day 21. As a result, the shoulder tilted more to the TKA side and the pelvis inclined more to the contralateral OA side. These results suggested that the trunk would bend away from the contralateral OA side after unilateral TKA in patients with bilateral end-stage knee OA and varus deformity. Asymmetry of the leg alignment led to asymmetric trunk bending. Copyright © 2013 Elsevier Inc. All rights reserved.

Disorders of mineral metabolism, including secondary hyperparathyroidism, are thought to contribute to extraskeletal (including vascular) calcification among patients with chronic kidney disease. It has been hypothesized that treatment with the calcimimetic agent cinacalcet might reduce the risk of death or nonfatal cardiovascular events in such patients. In this clinical trial, we randomly assigned 3883 patients with moderate-to-severe secondary hyperparathyroidism (median level of intact parathyroid hormone, 693 pg per milliliter [10th to 90th percentile, 363 to 1694]) who were undergoing hemodialysis to receive either cinacalcet or placebo. All patients were eligible to receive conventional therapy, including phosphate binders, vitamin D sterols, or both. The patients were followed for up to 64 months. The primary composite end point was the time until death, myocardial infarction, hospitalization for unstable angina, heart failure, or a peripheral vascular event. The primary analysis was performed on the basis of the intention-to-treat principle. The median duration of study-drug exposure was 21.2 months in the cinacalcet group, versus 17.5 months in the placebo group. The primary composite end point was reached in 938 of 1948 patients (48.2%) in the cinacalcet group and 952 of 1935 patients (49.2%) in the placebo group (relative hazard in the cinacalcet group vs. the placebo group, 0.93; 95% confidence interval, 0.85 to 1.02; P=0.11). Hypocalcemia and gastrointestinal adverse events were significantly more frequent in patients receiving cinacalcet. In an unadjusted intention-to-treat analysis, cinacalcet did not significantly reduce the risk of death or major cardiovascular events in patients with moderate-to-severe secondary hyperparathyroidism who were undergoing dialysis.

Deep brain stimulation (DBS) is an increasingly utilized therapeutic modality for the management of medication refractory essential tremor (ET). The aim of this study was to determine whether DBS allowed for anti-tremor medication reduction within the year after the procedure was performed. We conducted a retrospective chart review and telephone interviews on 34 consecutive patients who had been diagnosed with ET, and who had undergone unilateral DBS surgery. Of the 34 patients in our cohort, 31 patients (91%) completely stopped all anti-tremor medications either before surgery (21 patients, 62%) or in the year following DBS surgery (10 patients, 29%). Patients who discontinued tremor medications before DBS surgery did so because their tremors either became refractory to anti-tremor medication, or they developed adverse events to tremor medications. Patients who stopped tremor medications after DBS surgery did so due to sufficient tremor control. Only three patients (9%) who were taking tremor medications at the time of surgery continued the use of a beta-blocker post-operatively for the purpose of hypertension management in all cases. The data from this study indicate that medication cessation is common following unilateral DBS for ET.

Background Deep brain stimulation (DBS) is an increasingly utilized therapeutic modality for the management of medication refractory essential tremor (ET). The aim of this study was to determine whether DBS allowed for anti-tremor medication reduction within the year after the procedure was performed. Methods We conducted a retrospective chart review and telephone interviews on 34 consecutive patients who had been diagnosed with ET, and who had undergone unilateral DBS surgery. Results Of the 34 patients in our cohort, 31 patients (91%) completely stopped all anti-tremor medications either before surgery (21 patients, 62%) or in the year following DBS surgery (10 patients, 29%). Patients who discontinued tremor medications before DBS surgery did so because their tremors either became refractory to anti-tremor medication, or they developed adverse events to tremor medications. Patients who stopped tremor medications after DBS surgery did so due to sufficient tremor control. Only three patients (9%) who were taking tremor medications at the time of surgery continued the use of a beta-blocker post-operatively for the purpose of hypertension management in all cases. Discussion The data from this study indicate that medication cessation is common following unilateral DBS for ET. PMID:23440408

To analyse cognitive skills in patients with severe unilateral hearing loss versus those in subjects with normal hearing. 40 adults participated: 20 patients (10 women and 10 men) with severe unilateral hearing loss and 20 healthy subjects matched to the study group. Cognitive abilities were measured with the Spanish version of the Woodcock Johnson Battery-Revised; central auditory processing was assessed with monaural psychoacoustic tests. Box plots were drawn and t tests were performed for samples with a significance of P≤.05. A comparison of performances on the filtered word testing and time-compressed disyllabic word tests between patients and controls revealed a statistically significant difference (P≤.05) with greater variability among responses by hearing impaired subjects. This same group also showed a better cognitive performance on the numbers reversed, visual auditory learning, analysis synthesis, concept formation, and incomplete words tests. Patients with hearing loss performed more poorly than controls on the filtered word and time-compressed disyllabic word tests, but more competently on memory, reasoning, and auditory processing tasks. Complementary tests, such as those assessing central auditory processes and cognitive ability tests, are important and helpful for designing habilitation/rehabilitation and therapeutic strategies intended to optimise and stimulate cognitive skills in subjects with unilateral hearing impairment.

Kerr Winter, Ben; Odedra, Anand; Green, Steve

Medical tourism, where patients travel abroad intentionally to access medical treatment, is a growing trend. Some of these patients travel to undergo organ transplantation. This study aims to quantify the number of UK patients who undergo liver transplantation abroad, assessing their motivations and management. Questionnaires were sent to all seven UK liver transplant units enquiring about liver patients receiving transplant abroad. Included were questions on destination, motivation, and pre and post-transplant care. Responses were received from six of the seven transplant centres (86%). A total of 12 patients were identified as having undergone liver transplantation overseas. The top destinations were India, China and Egypt. Four units responded to questions regarding pre-transplant screening. One unit reported Hepatitis B and C screening not taking place. Four units responded to questions regarding post-transplant antimicrobial therapy. This revealed examples of patients inappropriately not receiving valganciclovir, co-trimoxazole, anti-fungal treatment and Hepatitis B immunoglobulins. UK patients are undergoing liver transplant abroad, albeit in small numbers. Pre and post-transplant management of these patients is of a lower standard than that provided to those undergoing transplantation in the UK. Information transfer between overseas and UK based transplant teams is poor. Copyright © 2016 Elsevier Ltd. All rights reserved.

Patients undergoing lobectomy are at significantly increased risk of lung injury. One-lung ventilation is the most commonly used technique to maintain ventilation and oxygenation during the operation. It is a challenge to choose an appropriate mechanical ventilation strategy to minimize the lung injury and other adverse clinical outcomes. In order to understand the available evidence, a systematic review was conducted including the following topics: (I) protective ventilation (PV); (II) mode of mechanical ventilation [e.g., volume controlled (VCV) versus pressure controlled (PCV)]; (III) use of therapeutic hypercapnia; (IV) use of alveolar recruitment (open-lung) strategy; (V) pre-and post-operative application of positive end expiratory pressure (PEEP); (VI) Inspired Oxygen concentration; (VII) Non-intubated thoracoscopic lobectomy; and (VIII) adjuvant pharmacologic options. The recommendations of class II are non-intubated thoracoscopic lobectomy may be an alternative to conventional one-lung ventilation in selected patients. The recommendations of class IIa are: (I) Therapeutic hypercapnia to maintain a partial pressure of carbon dioxide at 50–70 mmHg is reasonable for patients undergoing pulmonary lobectomy with one-lung ventilation; (II) PV with a tidal volume of 6 mL/kg and PEEP of 5 cmH2O are reasonable methods, based on current evidence; (III) alveolar recruitment [open lung ventilation (OLV)] may be beneficial in patients undergoing lobectomy with one-lung ventilation; (IV) PCV is recommended over VCV for patients undergoing lung resection; (V) pre- and post-operative CPAP can improve short-term oxygenation in patients undergoing lobectomy with one-lung ventilation; (VI) controlled mechanical ventilation with I:E ratio of 1:1 is reasonable in patients undergoing one-lung ventilation; (VII) use of lowest inspired oxygen concentration to maintain satisfactory arterial oxygen saturation is reasonable based on physiologic principles; (VIII) Adjuvant drugs

Enlarged thalamostriate vein causing unilateral Monro foramen obstruction. Case report.

PubMed

2009-06-01

Causes of unilateral hydrocephalus resulting from an obstruction at the Monro foramen include foraminal atresia, tumors, gliosis, contralateral shunting, and infectious and inflammatory conditions. However, few reports in the literature cite vascular lesions as the cause of the obstruction. To their knowledge, the authors present the first report of unilateral hydrocephalus occurring due to an abnormally enlarged thalamostriate vein independent of an arteriovenous malformation or developmental venous angioma. The condition was treated successfully by endoscopic septum pellucidum fenestration. A 28-year-old man was referred for evaluation due to a 10-year history of chronic headaches that worsened in severity over the past year. A CT scan of the head revealed unilateral right ventricular dilation. Cranial MR imaging with and without contrast administration showed a dilated right thalamostriate-internal vein complex without any evidence of associated arteriovenous malformation or venous angioma. Endoscopic exploration of the right lateral ventricle showed an enlarged subependymal thalamostriate vein obstructing the Monro foramen. An endoscopic fenestration of the septum pellucidum was performed, resulting in alleviation of the patient's symptoms. Abnormally enlarged venous structures may cause obstructive unilateral hydrocephalus and can be a rare cause of chronic, intermittent headaches in adults. Endoscopic fenestration of the septum pellucidum is an effective treatment.

A significant proportion of cancer patients at end of life (EOL) undergo radiotherapy, but this evidence is not from nationwide population-based studies. The aims of this population-based study were to investigate the trend in undergoing radiotherapy among Taiwanese cancer patients' last month of life (EOL radiotherapy) in 2001-2010 and to identify factors associated with EOL radiotherapy. This was a population-based retrospective cohort study analyzing data from Taiwan's national death registry, cancer registry, and National Health Insurance claims for EOL radiotherapy using multilevel generalized linear mixed modeling. Participants were Taiwanese cancer patients (N = 339,546) who died in 2001-2010. Overall, 8.59% (7.97%-9.85%) of patients underwent EOL radiotherapy with a decreasing trend over time. Correlates of EOL radiotherapy included male gender, younger age, residing in less urbanized areas, diagnosis of lung cancer, metastatic disease, death within two years of diagnosis, and without comorbidities. Cancer patients were more likely to undergo EOL radiotherapy if they received primary care from medical oncologists and pediatricians, in a nonprofit, teaching hospital with a larger case volume of terminally ill cancer patients, and greater EOL care intensity. Approximately one-tenth of Taiwanese cancer patients underwent EOL radiotherapy with a decreasing trend over time. Undergoing EOL radiotherapy was associated with demographics, disease characteristics, physician specialty, and primary hospital's characteristics and EOL care practice patterns. Clinical and financial interventions should target hospitals/physicians that tend to aggressively treat at-risk cancer patients at EOL to carefully evaluate the appropriateness and effectiveness of using EOL radiotherapy.

Perioperative risk associated with pulmonary hypertension (PH) in patients undergoing non-cardiac surgery (NCS) remains poorly defined. We report perioperative outcomes in a large cohort of patients undergoing NCS, comparing those with and without PH. Patients undergoing NCS at our institution between January 2002 and December 2006, were cross matched with a Right Heart Catheterization (RHC) database for the same period. Patients were excluded if they were <18 years old and if they underwent cardiac surgery prior to NCS or minor procedures using local anesthesia or sedation. Controls were defined as patients who underwent similar NCS with mean pulmonary arterial pressure (MPAP) ≤ 25 mmHg. 173 patients underwent RHC and NCS during the specified period and were included in the analysis. Of these 96 (55%) had PH. Mean pulmonary arterial pressure (p = 0.001), American Association of Anesthesiology Class (p = 0.02), and chronic renal insufficiency (p = 0.03) were determined as independent risk factors for post-operative morbidity. Patients with PH were more likely to develop congestive heart failure (p < 0.001; OR: 11.9), hemodynamic instability (p < 0.002), sepsis (p < 0.0005), and respiratory failure (p < 0.004). Patients with PH needed longer ventilatory support (p < 0.002), stayed longer in the ICU (p < 0.04), and were more frequently readmitted to the hospital within 30 days (p < 008; OR 2.4). In addition to the traditionally known risk factors for outcomes after NCS such as coronary artery disease, diabetes mellitus, chronic renal insufficiency, American Society of Anesthesiology class, the presence of underlying PH can have a significant negative impact on perioperative outcomes.

Optimizing perioperative outcomes for older patients with rheumatoid arthritis undergoing arthroplasty: emphasis on medication management.

PubMed

Goodman, Susan M

2015-05-01

Patients with rheumatoid arthritis continue to undergo arthroplasty despite widespread use of potent disease-modifying drugs (DMARDs), including the biologic tumor necrosis-α inhibitors. In fact, over 80 % of RA patients are taking DMARDs or biologics at the time of arthroplasty. While many RA-specific factors including disease activity and disability may contribute to the increase in infection in RA patients undergoing arthroplasty, immunosuppressant medications may also play a role. As the age of patients with RA undergoing arthroplasty is rising, and the incidence of arthroplasty among the older population is increasing, optimal perioperative management of DMARDs and biologics in older patients with RA is an increasing challenge. Although evidence is sparse, most evidence supports withholding tumor necrosis-α inhibitors and other biologics prior to surgery based on the dosing interval, and continuing methotrexate and hydroxychloroquine through the perioperative period. There is no consensus regarding leflunomide, and rituximab risk does not appear related to the interval between infusion and surgery. This paper reviews arthroplasty outcomes including complications in patients with RA, and discusses the rationale for strategies for the optimal medication management of DMARDs and biologics in the perioperative period to minimize complications and improve outcomes.

Glomerular filtration rate (GFR) is partially impaired in patients with multiple sclerosis (MS). When given chemotherapy before receiving hematopoietic stem-cell transplantation, GFR might be further deteriorated. To measure the effect of cyclophosphamide on GFR in patients with MS who undergo chemotherapy. We estimated GFR based on creatinine and cystatin C plasma concentrations in patients undergoing autologous hematopoietic stem-cell transplantation to treat their MS. Baseline GFR values were lower in the 28 patients with MS than in the 20 healthy individuals. Also, according to the Chronic Kidney Disease-Epidemiology Collaborative Group (CKD-EPI) 2012 Creat-CysC equation criteria, 4 of 28 patients were classified as having chronic kidney disease (CKD) before receiving the chemotherapy drugs. After receiving 4 × 50 mg per kg body weight cyclophosphamide, abnormal GFR results were recorded in 12 of 28 patients. Renal function must be monitored in patients with MS undergoing autologous stem-cell transplantation. Also, chemotherapy should be constrained as much as possible to prevent further deterioration of renal function.

The aim of this study was to compare the unilaterality of subarachnoid block achieved with hyperbaric and hypobaric ropivacaine. The prospective, randomized trial was conducted in an orthopedics surgical suite. In all, 60 ASA I-III patients scheduled for elective total knee arthroplasty were included in the study. Group Hypo (n=30) received 11.25mg of ropivacaine (7.5mg.mL(-1)) + 2mL of distilled water (density at room temperature was 0.997) and group Hyper (n=30) received 11.25mg of ropivacaine (7.5mg.mL(-1)) + 2mL (5mg.mL(-1)) of dextrose (density at room temperature was 1,015). Patients in the hyperbaric group were positioned with the operated side down and in the 15° Fowler position, versus those in the hypobaric group with the operated side facing up and in the 15° Trendelenburg position. Combined spinal epidural anesthesia was performed midline at the L(3-4) lumbar interspace. Hemodynamic and spinal block parameters, regression time, success of unilateral spinal anesthesia, patient comfort, surgical comfort, surgeon comfort, first analgesic requirement time, and adverse effects were assessed. Time to reach the T10 dermatome level on the operated side was shorter in group Hyper (612.00±163.29s) than in group Hypo (763.63±208.35s) (p<0.05). Time to 2-segment regression of the sensory block level on both the operated and non-operated sides was shorter in group Hypo than in group Hyper. Both hyperbaric and hypobaric ropivacaine (11.25mg) provided adequate and dependable anesthesia for total knee replacement surgery, with a high level of patient and surgeon comfort. Hypobaric local anesthetic solutions provide a high level of unilateral anesthesia, with rapid recovery of both sensory and motor block, and therefore may be preferable in outpatient settings.

Acute unilateral sensorineural hearing loss associated with anabolic steroids and polycythaemia: case report.

PubMed

Tikka, T; Mistry, N; Janjua, A

2016-03-01

Unilateral sudden sensorineural hearing loss due to an infarct in the vertebrobasilar system has been widely reported. Most patients have a background of traditional coronary risk factors related to these cerebrovascular episodes. A 32-year-old male, a regular user of anabolic steroids, presented to the emergency department with unilateral sensorineural hearing loss and symptoms suggestive of an infarct of the anterior inferior cerebellar artery but in the absence of risk factors for ischaemic stroke. Magnetic resonance imaging confirmed the presence of infarction in the region supplied by the anterior inferior cerebellar artery. Polycythaemia was found on haematological analysis, which we believe was secondary to the use of anabolic steroids. The patient was commenced on aspirin as per the stroke management protocol. There was resolution of neurological symptomatology six weeks after the episode, but no improvement in hearing. To our knowledge, this is the first case report of unilateral sensorineural hearing loss secondary to the use of anabolic steroids causing polycythaemia. This cause should be considered in the differential diagnosis of patients presenting with sensorineural hearing loss, especially in young males, when no other risk factors can be identified.

Successful use of right unilateral ECT for catatonia: a case series.

2014-03-01

Catatonia is a neuropsychiatric syndrome involving motor signs in association with disorders of mood, behavior, or thought. Bitemporal electrode placement electroconvulsive therapy (ECT) is a proven effective treatment for catatonia, and this mode of ECT delivery is the preferred method of treatment in this condition. Studies in major depressive disorder have demonstrated that suprathreshold, nondominant (right) hemisphere, unilateral electrode placement ECT has fewer adverse effects, especially cognitive adverse effects, than bitemporal ECT. This case series describes the use of right unilateral (RUL) ECT in 5 patients with catatonia. Before ECT, all 5 patients in this series initially failed therapy with benzodiazepines and psychotropic medications. Each catatonic patient received a series of 8 to 12 RUL ECT in an every-other-day series. After ECT, 4 of the 5 patients had a full recovery from catatonia. One patient achieved only partial response to RUL ECT, and no additional benefit was obtained with bitemporal ECT. All patients in this case series tolerated RUL ECT without major adverse effects. This case series illustrates successful use of RUL ECT in patients with catatonia and adds to the early literature demonstrating its effective use in treating this complex condition.

Objective This study was designed to compare the effectiveness of granisetron plus dexamethasone for preventing postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic surgery. Methods We searched the literature in the Cochrane Library, PubMed, EMBASE, and CNKI. Results In total, 11 randomized controlled trials were enrolled in this analysis. The meta-analysis showed that granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopy surgery. No significant differences in adverse reactions (dizziness and headache) were found in association with dexamethasone. Conclusion Granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopic surgery, with no difference in adverse reactions between the two groups. Granisetron alone or granisetron plus dexamethasone can be used to prevent PONV in patients undergoing laparoscopic surgery. PMID:28436248

2016-10-01

This study is to evaluate the dental arch relationship and palatal morphology of unilateral cleft lip and palate patients by using EUROCRAN index, and to assess the factors that affect them using multivariate statistical analysis. A total of one hundred and seven patients from age five to twelve years old with non-syndromic unilateral cleft lip and palate were included in the study. These patients have received cheiloplasty and one stage palatoplasty surgery but yet to receive alveolar bone grafting procedure. Five assessors trained in the use of the EUROCRAN index underwent calibration exercise and ranked the dental arch relationships and palatal morphology of the patients' study models. For intra-rater agreement, the examiners scored the models twice, with two weeks interval in between sessions. Variable factors of the patients were collected and they included gender, site, type and, family history of unilateral cleft lip and palate; absence of lateral incisor on cleft side, cheiloplasty and palatoplasty technique used. Associations between various factors and dental arch relationships were assessed using logistic regression analysis. Dental arch relationship among unilateral cleft lip and palate in local population had relatively worse scoring than other parts of the world. Crude logistics regression analysis did not demonstrate any significant associations among the various socio-demographic factors, cheiloplasty and palatoplasty techniques used with the dental arch relationship outcome. This study has limitations that might have affected the results, example: having multiple operators performing the surgeries and the inability to access the influence of underlying genetic predisposed cranio-facial variability. These may have substantial influence on the treatment outcome. The factors that can affect unilateral cleft lip and palate treatment outcome is multifactorial in nature and remained controversial in general. Copyright © 2016 Elsevier Ireland Ltd. All

Do patients with chronic unilateral orofacial pain due to a temporomandibular disorder show increased attending to somatosensory input at the painful side of the jaw?

Patients with chronic orofacial pain due to temporomandibular disorders (TMD) display alterations in somatosensory processing at the jaw, such as amplified perception of tactile stimuli, but the underlying mechanisms remain unclear. This study investigated one possible explanation, namely hypervigilance, and tested if TMD patients with unilateral pain showed increased attending to somatosensory input at the painful side of the jaw. TMD patients with chronic unilateral orofacial pain ( n  = 20) and matched healthy volunteers ( n  = 20) performed a temporal order judgment (TOJ) task indicated which one of two tactile stimuli, presented on each side of the jaw, they had perceived first. TOJ methodology allows examining spatial bias in somatosensory processing speed. Furthermore, after each block of trials, the participants rated the perceived intensity of tactile stimuli separately for both sides of the jaw. Finally, questionnaires assessing pain catastrophizing, fear-avoidance beliefs, and pain vigilance, were completed. TMD patients tended to perceive tactile stimuli at the painful jaw side as occurring earlier in time than stimuli at the non-painful side but this effect did not reach conventional levels of significance ( p  = .07). In the control group, tactile stimuli were perceived as occurring simultaneously. Secondary analyses indicated that the magnitude of spatial bias in the TMD group is positively associated with the extent of fear-avoidance beliefs. Overall, intensity ratings of tactile stimuli were significantly higher in the TMD group than in the control group, but there was no significant difference between the painful and non-painful jaw side in the TMD patients. The hypothesis that TMD patients with chronic unilateral orofacial pain preferentially attend to somatosensory information at the painful side of the jaw was not statistically supported, although lack of power could not be ruled out as a reason for this. The findings are discussed within

OBJECTIVES Video-assisted thoracoscopic sympathectomy is currently the best treatment for palmar and axillary hyperhidrosis. It can be performed through either one or two stages of surgery. This study aimed to evaluate the operative and postoperative results of two-stage unilateral vs one-stage bilateral thoracoscopic sympathectomy. METHODS From November 1995 to February 2011, 270 patients with severe palmar and/or axillary hyperhidrosis were recruited for this study. One hundred and thirty patients received one-stage bilateral, single-port video-assisted thoracoscopic sympathectomy (one-stage group) and 140, two-stage unilateral, single-port video-assisted thoracoscopic sympathectomy, with a mean time interval of 4 months between the procedures (two-stage group). RESULTS The mean postoperative follow-up period was 12.5 (range: 1–24 months). After surgery, hands and axillae of all patients were dry and warm. Sixteen (12%) patients of the one-stage group and 15 (11%) of the two-stage group suffered from mild/moderate pain (P = 0.8482). The mean operative time was 38 ± 5 min in the one-stage group and 39 ± 8 min in the two-stage group (P = 0.199). Pneumothorax occurred in 8 (6%) patients of the one-stage group and in 11 (8%) of the two-stage group. Compensatory sweating occurred in 25 (19%) patients of the one-stage group and in 6 (4%) of the two-stage group (P = 0.0001). No patients developed Horner's syndrome. CONCLUSIONS Both two-stage unilateral and one-stage bilateral single-port video-assisted thoracoscopic sympathectomies are effective, safe and minimally invasive procedures. Two-stage unilateral sympathectomy can be performed with a lower occurrence of compensatory sweating, improving permanently the quality of life in patients with palmar and axillary hyperhidrosis.

The utility of routine preoperative electrocardiography (ECG) for assessing perioperative cardiovascular risk in patients undergoing noncardiac, nonvascular surgery (NCNVS) is unclear. There would be an association between preoperative ECG and perioperative cardiovascular outcomes in patients undergoing NCNVS. A total of 660 patients undergoing NCNVS were prospectively evaluated. Patients age >18 years who underwent an elective, nonday case, open surgical procedure were enrolled. Troponin I concentrations and 12-lead ECG were evaluated the day before surgery, immediately after surgery, and on the first 5 postoperative days. Preoperative ECG showing atrial fibrillation, left or right bundle branch block, left ventricular hypertrophy, frequent premature ventricular complexes, pacemaker rhythm, Q-wave, ST-segment changes, or sinus tachycardia or bradycardia were classified as abnormal. The patients were followed up during hospitalization and were evaluated for the presence of perioperative cardiovascular events (PCE). Eighty patients (12.1%) experienced PCE. Patients with abnormal ECG findings had a greater incidence of PCE than those with normal ECG results (16% vs 6.4%; P < 0.001). Mean QTc interval was significantly longer in the patients who had PCE (436.6 ± 31.4 vs 413.3 ± 16.7 ms; P < 0.001). Univariate analysis showed a significant association between preoperative atrial fibrillation, pacemaker rhythm, ST-segment changes, QTc prolongation, and in-hospital PCE. However, only QTc prolongation (odds ratio: 1.15, 95% confidence interval: 1.06-1.2, P < 0.001) was an independent predictor of PCE according to the multivariate analysis. Every 10-ms increase in QTc interval was related to a 13% increase for PCE. Prolongation of the QTc interval on the preoperative ECG was related with PCE in patients undergoing NCNVS. © 2011 Wiley Periodicals, Inc.

Children with unilateral spastic cerebral palsy (CP) often have mirror movements, i.e. involuntary imitations of unilateral voluntary movements of the contralateral upper extremity. The pathophysiology of mirror movements has been investigated in small and heterogeneous cohorts in the literature. Specific pathophysiology of mirror movements and their impact on upper extremity function require systematic investigation in larger and homogeneous cohorts of children with unilateral spastic CP. Here we review two possible neurophysiological mechanisms underlying mirror movements in children with CP and those with typical development: (1) an ipsilateral corticospinal tract projecting from the contralesional motor cortex (M1) to both upper extremities; (2) insufficient interhemispheric inhibition between the two M1s. We also discuss clinical implications of mirror movements in children with unilateral CP and suggest that a thorough examination of the relationship between the pathophysiology and clinical manifestations of mirror movements is warranted. We suggest two premises: (1) the presence of mirror movements is indicative of an ipsilateral corticospinal tract reorganization; and (2) the corticospinal tract organization may affect patients' responses to certain treatment. If these premises are supported through future research, mirror movements should be clinically evaluated for patient selection to maximize benefits of therapy, hence promoting individualized medicine in this population. Mirror movements may be indicative of the underlying corticospinal tract reorganization in children with unilateral spastic cerebral palsy (CP). Future research will benefit from systematic investigations of the relationship between mirror movements and its pathophysiology. Mirror movements may be a potential biomarker for individualized medicine in children with unilateral spastic CP. © 2017 Mac Keith Press.

To compare the short- and long-term clinical outcomes, operation times, restoration rate, dosage of polymethylmeth-acrylate (PMMA) injected, complications and X-rays exposure frequency between unilateral and bilateral kyphoplasty approaches for the treatment of OVCF. Systematic review and meta-analysis. Randomized or non-randomized controlled trials published up to April 2015 that compared the unilateral and bilateral PKP for the treatment of OVCF were acquired by a comprehensive search in the Cochrane Controlled Trial Register, PubMed, MEDLINE, EMBASE, Web of Science, OVID. Exclusion criteria were patients with neoplastic etiology (metastasis or myeloma), infection, neural compression syndrome, invasive and degenerative disease, traumatic fracture, re-operation, neurological deficits, significant scoliosis and spinal stenosis. The main end points included: operation times, the short- and long-term postoperative Visual Analogue Scale (VAS) scores, the short-term postoperative Oswestry Disability Index (ODI), restoration rate, dosage of PMMA injected, cement leakage, X-ray exposure frequency and postoperative adjacent-level fractures. A total of 8 studies involving 428 patients were included in the meta-analysis. The mean operative time was shorter in the unilateral groups compared with the bilateral groups [P < 0.05, weighted mean difference (WMD) -19.74 (-30.56, -8.92)]. There was no significant difference in the short-term postoperative VAS scores [P > 0.05, WMD 0.03 (-0.34, 0.40)], the long-term postoperative VAS scores between them [P > 0.05, WMD 0.01 (-0.42, 0.45)] and the short-term postoperative ODI [P > 0.05, WMD -0.33 (-2.36, 1.69)] between the two groups. The unilateral approaches required significantly less dosage of PMMA than the bipedicular approaches did [P < 0.05, WMD -1.56 (-1.59, -1.16)]. The restoration rate in the bilateral groups was higher than the unilateral groups [P < 0.05, WMD -7.82 (-12.23, -3.41)]. There was no significant

Forced-Air Warmers and Surgical Site Infections in Patients Undergoing Knee or Hip Arthroplasty.

The majority of the evidence indicates preventing inadvertent perioperative hypothermia reduces the incidence of many perioperative complications. Among the results of inadvertent perioperative hypothermia are increased bleeding, myocardial events, impaired wound healing, and diminished renal function. Most researchers agree there is an increased incidence of surgical site infections in patients who experience inadvertent perioperative hypothermia. Forced-air warming is effective in preventing inadvertent perioperative hypothermia. Paradoxically, forced-air warmers have been implicated in causing surgical site infections in patients undergoing total knee or hip arthroplasty. The results of investigations suggest these devices harbor pathogens and cause unwanted airflow disturbances. However, no significant increases in bacterial counts were found when forced-air warmers were used according to the manufacturer's directions. The results of one study suggested the incidence of surgical site infections in patients undergoing total joint arthroplasty was increased when using a forced-air warmer. However these researchers did not control for other factors affecting the incidence of surgical site infections in these patients. Current evidence does not support forced-air warmers causing surgical site infections in patients undergoing total knee or hip arthroplasty. Clinicians must use and maintain these devices as per the manufacturer's directions. They may consider using alternative warming methods. Well-conducted studies are needed to help determine the role of forced-air warmers in causing infections in these patients.

Objective To determine in individuals with unilateral cleft lip and palate the correlation between initial cleft size and dental anomalies, and the outcome of alveolar bone grafting. Methods A total of 67 consecutive patients with non-syndromic unilateral complete cleft lip and palate (UCLP) were included from the cleft lip and palate-craniofacial center, Uppsala University Hospital, Sweden. All patients were operated by the same surgeon and treated according to the Uppsala protocol entailing: lip plasty at 3 months, soft palate closure at 6 months, closure of the residual cleft in the hard palate at 2 years of age, and secondary alveolar bone grafting (SABG) prior to the eruption of the permanent canine. Cleft size was measured on dental casts obtained at the time of primary lip plasty. Dental anomalies were registered on radiographs and dental casts obtained before bone grafting. Alveolar bone height was evaluated with the Modified Bergland Index (mBI) at 1 and 10-year follow-up. Results Anterior cleft width correlated positively with enamel hypoplasia and rotation of the central incisor adjacent to the cleft. There was, however, no correlation between initial cleft width and alveolar bone height at either 1 or 10 years follow-up. Conclusions Wider clefts did not seem to have an impact on the success of secondary alveolar bone grafting but appeared to be associated with a higher degree of some dental anomalies. This finding may have implications for patient counseling and treatment planning.

Our primary objective was to assess the feasibility of geriatric patients (>65 yr) bypassing the postanesthesia care unit (PACU) after ambulatory surgery. A secondary objective was to compare recovery profiles when using three different maintenance anesthetics. Ninety ASA physical status I--III consenting outpatients (>65 yr) undergoing short urologic procedures were randomly assigned to one of three anesthetic treatment groups. After a standardized induction with fentanyl and propofol, anesthesia was maintained with propofol (75-150 microg center dot kg(-1) center dot min(-1) IV), isoflurane (0.7%-1.2% end tidal), or desflurane (3%-6% end tidal), in combination with nitrous oxide 70% in oxygen. In all three groups, the primary anesthetic was titrated to maintain an electroencephalographic-bispectral index value of 60-65. Recovery times, postanesthesia recovery scores, and therapeutic interventions in the PACU were recorded. Although emergence times were similar in the three groups, the time to achieve a fast-track discharge score of 14 was significantly shorter in patients receiving desflurane compared with propofol and isoflurane (22 +/- 23 vs 33 +/- 25 and 44 +/- 36 min, respectively). On arrival in the PACU, a significantly larger percentage of patients receiving desflurane were judged to be fast-track eligible compared with those receiving either isoflurane and propofol (73% vs 43% and 44%, respectively). The number of therapeutic interventions in the PACU was also significantly larger in the Isoflurane group when compared with the Propofol and Desflurane groups (21 vs 11 and 7, respectively). In conclusion, use of desflurane for maintenance of anesthesia should facilitate PACU bypass ("fast-tracking") of geriatric patients undergoing short urologic procedures. Geriatric outpatients undergoing brief urologic procedures more rapidly achieve fast-tracking discharge criteria after desflurane (versus isoflurane and propofol) anesthesia. Use of isoflurane was also

This article reports the case of a 44-year-old male with skeletal Class III, Angle Class III malocclusion and unilateral crossbite with concerns about obstructive sleep apnea syndrome (OSAS), esthetics and functional problems. To correct the skeletal deformities, the maxilla was anteriorly repositioned by employing LeFort I osteotomy following pre-surgical orthodontic treatment, because a mandibular setback might induce disordered breathing and cause OSAS. After active treatment for 13 months, satisfactory occlusion was achieved and an acceptable facial and oral profile was obtained. In addition, the apnea hypopnea index (AHI) decreased from 18.8 preoperatively to 10.6 postoperatively. Furthermore, after a follow-up period of 7 months, the AHI again significantly decreased from 10.6 to 6.2. In conclusion, surgical advancement of the maxilla using LeFort I osteotomy has proven to be useful in patients with this kind of skeletal malocclusion, while preventing a worsening of the OSAS.

ECT is the most effective treatment for severe depression. Previous efficacy studies, using thrice-weekly brief-pulse ECT, reported that high-dose (6× seizure threshold) right unilateral ECT is similar to bitemporal ECT but may have fewer cognitive side effects. The authors aimed to assess the effectiveness and cognitive side effects of twice-weekly moderate-dose (1.5× seizure threshold) bitemporal ECT with high-dose unilateral ECT in real-world practice. This was a pragmatic, patient- and rater-blinded, noninferiority trial of patients with major depression (N=138; 63% female; age=56.7 years [SD=14.8]) in a national ECT service with a 6-month follow-up. Participants were independently randomly assigned to bitemporal or high-dose unilateral ECT. The primary outcome was change in the 24-item Hamilton Depression Rating Scale (HAM-D) score after the ECT course; the prespecified noninferiority margin was 4.0 points. Secondary outcomes included response and remission rates, relapse status after 6 months, and cognition. Of the eligible patients, 69 were assigned to bitemporal ECT and 69 to unilateral ECT. High-dose unilateral ECT was noninferior to bitemporal ECT regarding the 24-item HAM-D scores after the ECT course (mean difference=1.08 points in favor of unilateral ECT [95% CI=-1.67 to 3.84]). There were no significant differences for response and remission or 6-month relapse status. Recovery of orientation was quicker following unilateral ECT (median=19.1 minutes versus 26.4 minutes). Bitemporal ECT was associated with a lower percent recall of autobiographical information (odds ratio=0.66) that persisted for 6 months. Twice-weekly high-dose unilateral ECT is not inferior to bitemporal ECT for depression and may be preferable because of its better cognitive side-effect profile.

It has not been established whether unilateral or bilateral hip dual-energy X-ray absorptiometry (DXA) is preferable for the diagnosis of osteoporosis. We investigated the discordance in DXA measurements in bilateral hips to determine whether unilateral DXA is valid for osteoporosis diagnosis. The subjects were 2964 Japanese patients without a previous diagnosis of primary osteoporosis. We measured bilateral femoral bone mineral density (BMD) and calculated indices, related to the unilateral results, for predicting contralateral hip osteoporosis. A likelihood ratio (LR) of a negative test (LR [-]) of less than 0.2 was considered to exclude the diagnosis. In the normal spinal BMD group, the sensitivity of unilateral DXA for women was 27-73% and LR (-) was 0.28-0.73; the sensitivity for men was 0-50% and LR (-) was 0.51-1.00; the diagnosis of contralateral osteoporosis was not excluded. Sensitivity increased and LR (-) increased with worsening spinal BMD status; however, LR (-) did not meet the cutoff for exclusion. We could exclude unilateral hip osteoporosis, in women only, by performing contralateral femoral DXA; this necessitated lowering the T-score cutoff from -2.5 to -2.0. Unilateral femoral DXA is not useful for excluding the diagnosis of contralateral hip osteoporosis. Copyright © 2014 The International Society for Clinical Densitometry. Published by Elsevier Inc.

We aimed to determine the prevalence and co-occurrence of tobacco smoking, alcohol consumption, and depressive symptoms among a sample of head and neck cancer (HNC) patients undergoing radiotherapy. A total of 307 HNC patients participated in a multi-site stepped-wedge randomized controlled trial (RCT) evaluating the effectiveness of a dietitian-delivered health behavior intervention in patients with HNC undergoing radiotherapy. During week one of radiotherapy patients completed measures of smoking, alcohol consumption, and level of depression. Approximately one-fifth (21%) of patients had two or more co-occurring problems: current smoking, hazardous alcohol use, and/or likely presence of a major depressive episode (MDE). Approximately one-third (34%) of the sample were current smokers, one-third (31%) were drinking hazardously and almost one-fifth (19%) had likely cases of depression. Comorbidity of smoking, hazardous alcohol use, and MDE is high in HNC patients, and interventions need to address this cluster of cancer risk factors. © 2018 The Authors.

There is variation in the literature in regard to the occurrence of unilateral vocal fold paralysis (UVFP) after congenital cardiothoracic surgery. The objective of this study was to identify and appraise the evidence for the occurrence of UVFP after congenital cardiothoracic surgery in a meta-analysis. A comprehensive search strategy in Medline, Embase, and the Cochrane Library was conducted, limited to English publications. Two independent reviewers screened studies for eligibility criteria. Of the 162 identified studies, 32 (20%) met the inclusion criteria. Using the Oxford Centre for Evidence-Based Medicine guidelines, 2 reviewers appraised the level of evidence, extracted data, and resolved discrepancies by consensus. Weighted pooled proportion and 95% confidence intervals (CIs) are reported. Thirty-two studies (n = 5625 patients) were included. Levels of evidence varied from level 3 to 4. Among all studies, the weighted pooled proportion of UVFP was 9.3% (95% CI, 6.6% to 12.5%), and among 11 studies (n = 584 patients) that postoperatively evaluated patients with flexible nasopharyngolaryngoscopy to document presence of UVFP, the weighted pooled proportion of UVFP was 29.8% (95% CI, 18.5% to 42.5%). Twenty-one studies (n = 2748 patients) evaluated patients undergoing patent ductus arteriosus ligation surgery, and the weighted pooled proportion of UVFP was 8.7% (95% CI, 5.4% to 12.6%). Six of these (n = 274 patients) assessed all patients postoperatively, and the weighted pooled proportion of UVFP was 39% (95% CI, 18% to 63%). Pooled analyses of risk factors and comorbidities are reported. Heterogeneity and publication bias were detected. UVFP is a demonstrated risk of congenital cardiothoracic surgery. Routine postoperative nasopharyngolaryngoscopy for vocal fold assessment by an otolaryngologist is suggested. Copyright © 2014 by the American Academy of Pediatrics.

Ipsilateral visual illusion after unilateral posterior cerebral artery infarction: a report of two cases.

In cases of unilateral posterior cerebral artery (PCA) infarction, abnormal visual perception in the ipsilateral visual field, which is usually believed to be intact, is not met frequently and may confuse doctors during evaluation. Recently, we observed two patients who presented with contralateral hemianopsia accompanied by ipsilateral visual illusions after acute unilateral PCA infarctions. Their visual illusion was characterized by zooming in, macropsia or micropsia. These symptoms appeared to be related to deficits in size constancy. Lesions of both patients commonly involved the ipsilateral forceps major. The consistent presentation observed in these two patients suggests that dominance of size constancy can be located in the left hemisphere in some individuals. Copyright (c) 2010 Elsevier B.V.

PURPOSE We aimed to determine the radiation doses delivered to patients undergoing general examinations using computed or digital radiography systems in Turkey. MATERIALS AND METHODS Radiographs of 20 patients undergoing posteroanterior chest X-ray and of 20 patients undergoing anteroposterior kidney-ureter-bladder radiography were evaluated in five X-ray rooms at four local hospitals in the Ankara region. Currently, almost all radiology departments in Turkey have switched from conventional radiography systems to computed radiography or digital radiography systems. Patient dose was measured for both systems. The results were compared with published diagnostic reference levels (DRLs) from the European Union and International Atomic Energy Agency. RESULTS The average entrance surface doses (ESDs) for chest examinations exceeded established international DRLs at two of the X-ray rooms in a hospital with computed radiography. All of the other ESD measurements were approximately equal to or below the DRLs for both examinations in all of the remaining hospitals. Improper adjustment of the exposure parameters, uncalibrated automatic exposure control systems, and failure of the technologists to choose exposure parameters properly were problems we noticed during the study. CONCLUSION This study is an initial attempt at establishing local DRL values for digital radiography systems, and will provide a benchmark so that the authorities can establish reference dose levels for diagnostic radiology in Turkey.

Preoperative vocal fold paralysis (VFP) is thought to be rare in patients with benign thyroid disease (BTD). In contrast with cases of malignancy, in which the recurrent laryngeal nerve (RLN) should be severed, in patients with BTD and VFP the RLN can be preserved without threatening patients' lives. This study investigates the clinical features that enable identification of patients who have VFP associated with BTD. Medical records of 187 consecutive patients who underwent thyroid surgery were retrospectively reviewed. The association between preoperative VFP and pathology (benign or malignant), clinical features, and treatment results of patients with BTD and VFP were analyzed. Of the 187 patients, 145 patients had BTD and 8 of these cases (5.52%) had preoperative unilateral VFP. The prevalence of BTD with VFP was 4.3% (8/187). The other 42 patients had malignant thyroid disease and 4 of these cases (9.52%) had preoperative unilateral VFP. None of the aforementioned VFP was caused by previous thyroidectomy or surgery to the neck. Although the relative risk of VFP in patients with thyroid malignancy was 1.726 (9.52%/5.52%), there was no significant association between VFP and malignancy. Of the eight patients with BTD, benign fine-needle aspiration cytology or frozen sections, goiter with a diameter larger than 5 cm, cystic changes, and significant radiologic tracheo-esophageal groove compression were the common findings. During thyroidectomy, the RLN was injured but repaired in three patients. Two events occurred in patients who had severe RLN adhesion to the tumor caused by thyroidectomy performed decades ago. Two of the five patients without nerve injury recovered vocal fold function. The overall VFP recovery rate for patients with BTD and VFP was 25% (2/8). Preoperative unilateral VFP is not uncommon in thyroid surgery. Obtaining information on laryngeal function is of extreme importance when planning surgery, especially contralateral surgery.

Both diabetes mellitus and hyperglycemia per se are associated with negative outcomes after cardiac surgery. In this article, we review these associations, the possible mechanisms that lead to adverse outcomes, and the epidemiology of diabetes focusing on those patients requiring cardiac surgery. We also examine outpatient and perioperative management of diabetes with the same focus. Finally, we discuss our own efforts to improve glycemic management of patients undergoing cardiac surgery at our institution, including keys to success, results of implementation, and patient safety concerns.

Previous studies performed in non-obese patients undergoing elective surgery have revealed that psychological factors may affect postoperative analgesic requirements. The aim of this observational prospective study was to investigate the extent to which psychopathological dimensions, including anxiety, depression and alexithymia, may influence postoperative pain intensity and analgesics consumption using patient-controlled analgesia (PCA) in patients undergoing bariatric surgery. 120 patients, aged 18-60years, with an ASA physical status I-II, undergoing gastric bypass were enrolled. Anxiety and depression Hamilton scales, and Toronto Alexithymia scale, were administered to patients on the day before surgery. General anesthesia was standardized. After awakening, a PCA pump with intravenous tramadol was immediately made available for a 36-hour postoperative analgesia. Visual analog scale at rest (VASr) and after coughing (VASi), and effective PCA requests number were postoperatively recorded. Pearson's correlations, Anova analyses and multiple linear regression were used for statistical purpose. Positive correlations were found between anxiety, depression, alexithymia and all pain indicators (p<0.01). Analyses of variance showed that anxious (p<0.001), depressed (p<0.001) and alexithymic (p<0.05) patients had high pain indicators. VASr and VASi were predicted by anxiety and depression (p<0.05), but not by alexithymia; effective PCA requests number was predicted by anxiety, depression and alexithymia (p<0.001). Obese patients with high depression, anxiety and alexithymia levels rated their pain as more intense and required a larger amount of tramadol. Pain perception intensity was predicted by anxiety and depression but not by alexithymia, whereas analgesics consumption was predicted by all the investigated psychopathological dimensions.

Despite selection process before awake-craniotomy, some patients experience an unexpected decline in language functions in the operating room (OR), compared with their baseline evaluation, which may impair their functional monitoring. To investigate this phenomenon we prospectively compared language function the day before surgery and on entrance to the OR. Data were collected prospectively from consecutive patients undergoing awake-craniotomy with intraoperative cortical mapping for resection of gliomas affecting language areas. Language functions of 79 patients were evaluated and compared 1-2 days before surgery and after entering the OR. Changes in functional linguistic performance were analyzed with respect to demographic, clinical, and pathologic characteristics. There was a significant decline in language function, beyond sedation effect, after entering the OR, (from median/interquartile range: 0.94/0.72-0.98 to median/interquartile range: 0.86/0.51-0.94; Z = -7.19, P < 0.001). Univariate analyses revealed that this decline was related to age, preoperative Karnofsky Performance Scale, tumor location, tumor pathology, and preexisting language deficits. Multivariate stepwise regression identified tumor pathology and the presence of preoperative language deficit as significant independent predictors for this functional decline. Patients undergoing awake-craniotomy may experience a substantial decline in language functioning after entering the OR. Tumor grade and the presence of preoperative language deficits were significant risk factors for this phenomenon, suggesting a possible relation between cognitive reserve, psychobehavioral coping abilities and histologic features of a tumor involving language areas. Capturing and identifying this unique population of patients who are prone to experience such language decline may improve our ability in the future to select patients eligible for awake-craniotomy.

Pectus excavatum (PEx) is one of the most common congenital chest wall deformities. Depending on the severity, presentation of PEx may range from minor cosmetic issues to disabling cardiopulmonary symptoms. The effect of PEx on adult patients has not been extensively studied. Symptoms may not occur until the patient ages, and they may worsen over the years. More recent publications have implied that PEx may have significant cardiopulmonary implications and repair is of medical benefit. Adults presenting for PEx repair can undergo a successful repair with a minimally invasive “Nuss” approach. Resolution of symptoms, improved quality of life, and satisfying results are reported.

The aim of this study was to characterize the pharmacokinetics (PK) of propofol in ICU patients undergoing long-term sedation and to assess the influence of routinely collected covariates on the PK parameters. Propofol concentration-time profiles were collected from 29 patients. Non-linear mixed-effects modelling in NONMEM 7.2 was used to analyse the observed data. The propofol pharmacokinetics was best described with a three-compartment disposition model. Non-parametric bootstrap and a visual predictive check were used to evaluate the adequacy of the developed model to describe the observations. The typical value of the propofol clearance (1.46 l/min) approximated the hepatic blood flow. The volume of distribution at steady state was high and was equal to 955.1 l, which is consistent with other studies involving propofol in ICU patients. There was no statistically significant covariate relationship between PK parameters and opioid type, SOFA score on the day of admission, APACHE II, predicted death rate, reason for ICU admission (sepsis, trauma or surgery), gender, body weight, age, infusion duration and C-reactive protein concentration. The population PK model was developed successfully to describe the time-course of propofol concentration in ICU patients undergoing prolonged sedation. Despite a very heterogeneous group of patients, consistent PK profiles were observed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Objective We aimed to compare the efficacy of spinal anaesthesia (SA) and paravertebral block (PVB) in unilateral inguinal hernia repair. Methods Sixty American Society of Anesthesia physical status (ASA) I–III patients aged between 18–64 years with unilateral inguinal hernia were enrolled in this study. Two patients in Group SA and 4 patients in Group PVB were excluded, and statistical analyses were done on 54 patients. In regard to anaesthetic choice, patients were divided into two groups, with 30 patients in each: Group SA, spinal anaesthesia and Group PVB, paravertebral block. Standard monitoring was done, and mean arterial pressure (MAP) and heart rate (HR) were recorded during the surgical procedure. Demographic variables, surgical data, patient satisfaction, the onset times to reach T10 dermatome and to reach peak sensory level, and onset time to reach modified Bromage 3 motor block were recorded. Postoperative nausea and vomiting and pain at postoperative hours 0–24 with the visual analog scale (VAS) were also measured. Results Compared to pre-anaesthesia measurements, the decrease in HR and MAP during the 10th–90th minute period was significant in Group SA (p<0.01). In Group PVB, sensory block duration time was higher, whereas paralysis rate was higher in Group SA (p<0.01). Bromage scores were significantly different between the groups (p<0.01). In Group SA, VAS score at the 24th postoperative hour, nausea, and vomiting were significantly higher compared to Group PVB (p<0.01). Conclusion In conclusion, paravertebral block provides acceptable surgical anaesthesia, maintaining good quality and long duration on postoperative analgesia in unilateral hernia repair. PMID:27366432
