    Objective: To evaluate and compare the two methods, electrocautery versus chemical cautery, for controlling unilateral anterior epistaxis and to identify the complications. Design: Randomized control trial. Place and Duration: This study was conducted in ENT Department PNS Shifa Hospital Karachi from August 2009 to June 2011. Patients and Methods: Ninety two cases with unilateral anterior epistaxis were divided using random number trials into two groups i.e. group A and group B containing 46 cases each. In group A electrocautery and in group B chemical cautery with 50% silver nitrate was done and the results were compared. Results: In this study 92 cases were divided randomly into two groups i.e. group A and group B containing 46 cases in each group. In group A 44 (95.6%) out of 46 cases were treated successfully with a single visit as an outpatient by electrocautery, the patients were called for follow up on the fifth day and then fortnightly for three months after the procedure, only 2 (4.3%) cases reported in first five days with mild recurrence of bleeding. In group B 42 (91.3%) cases out of 46 cases were treated successfully in a single visit and recurrence of bleeding occured in 4 (8.7%) cases who required a second visit during the first five days. There were no major complications found in either group except few complaints of post cauterization pain and mucosal inflammation observed slightly more in group B patients. Conclusion: Electrocautery and chemical cautery with 50% silver nitrate both are equally effective procedures to control anterior epistaxis if the bleeding point is visible and small. Both procedures are reliable and there are no major complications. Occasionally if the bleeding point in the anterior nasal septum is large then electrocautery may be a preferred option. (author)

    Full Text Available Background The current study aimed to evaluate the postural control in patients underwent anterior cruciate ligament reconstruction pre and post wearing functional knee brace. Methods Eighteen athletes undergone unilateral anterior cruciate ligament reconstruction included in the study. They had unilateral anterior cruciate ligament reconstruction at least six months before session test. Postural control was assessed pre and post wearing custom-fit functional knee brace using a posturographic platform prokin 254. The balance tests included: 1 standing on prokin platform with eyes open/closed on anterior cruciate ligament reconstruction limb, 2 standing on prokin platform with eyes open/closed on both limbs. The standard deviation (SD of body sway along the anteroposterior (AP and mediolateral (ML axis, mean velocity of center of pressure (COP along AP/ ML axis and the area ellipse (measured in 2 mm were calculated. Results Results of the paired T-test revealed a significant effect on selected postural control variables for the brace conditions especially in low challengeable conditions (double leg, eyes open test situations (P < 0.05. But in high challengeable conditions this effect was not significant. Conclusions Functional knee brace improved postural control in the simple balancing task in the subjects with anterior cruciate ligament reconstruction. But this improvement in more difficult balancing task was limited.

    Full Text Available Abstract Background Zoledronic acid is very widely used in patients with metastatic bone disease and osteoporosis. Only one case of bilateral uveitis was recently reported related to its use. Case presentation We report the first case of severe unilateral anterior uveitis in a patient with breast cancer and an intraocular lens. Following zoledronic acid infusion, the patient developed severe and dramatic right eye pain with decreased visual acuity within 24 hours and was found to have a fibrinous anterior uveitis of moderate severity The patient was treated with topical prednisone and atropine eyedrops and recovered slowly over several months. Conclusion Internists, oncologists, endocrinologists, and ophtalmologists should be aware of uveitis as a possible complication of zoledronic acid therapy. Patients should be instructed to report immediately to their physicians and treatment with topical prednisone and atropine eyedrops should be instituted immediately at the onset of symptoms. This report documents anterior uveitis as a complication of zoledronic acid therapy. This reaction could be an idiosyncratic one but further research may shed more light on the etiology.

    Animal research demonstrated that during fear conditioning the amygdala plays a central role in forming an association between the conditioned stimulus (CS) and the unconditioned stimulus (US). Lesion studies conducted in patients who underwent a unilateral anterior temporal lobe resection, however; yielded contradictory findings. To date, it remains unclear whether amygdala damage only affects fear-conditioned startle responding or impairs both the latter and fear-conditioned skin conductance responding (SCR). Moreover inconsistency exists regarding the preservation of contingency knowledge in amygdala-damaged patients. In the current study, a differential fear conditioning task was presented to a unilaterally amygdala-damaged patient group and a healthy control group, recording fear-potentiated startle responses along with SCRs. Retrospectively, the valence of the CSs and contingency awareness was assessed. Unlike the control group, unilaterally amygdala-damaged patients showed neither in their SCRs nor in their valence ratings an effect of fear conditioning. The startle data, however, yielded in none of the two test groups fear-conditioned responding. Finally, considerably fewer patients (37.5%) than controls (95%) acquired correct memory of the presented contingency. Based on these findings we concluded that the fear conditioning impairment in amygdala-damaged patients was not restricted to SCRs, but also affected valence ratings and memory of the presented contingency. A broader theory of the amygdala as relevance detector is proposed in order to account for the diverse neurological findings obtained so far.

    Anterior uveitis is the most common form of intraocular inflammation. The main aim of this study was to determine the viral etiology in patients with unilateral cases of anterior uveitis. A total of 12 consecutive patients with the diagnosis of idiopathic unilateral anterior uveitis were included prospectively. Aqueous specimens were obtained from each patient by anterior chamber paracentesis and subjected to the detection of viral DNA/RNA genome by polymerase chain reaction assay for herpes simplex virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, and rubella virus. There were six male and six female patients. The mean age was 43 years, with an age range of 11-82 years. All 12 cases presented with unilateral anterior uveitis. In four (33%) patients, polymerase chain reaction was positive for viral genome. Two patients were positive for herpes simplex virus type 1, one patient was positive for cytomegalovirus and one for Epstein-Barr virus. Recent molecular diagnostic assays would help in the identification of the causative agent in patients with unilateral anterior uveitis.

    Full Text Available Introduction: Quality of life can be defined as the expression of aconceptual model that tries to represent patient’s perspectivesand his/her level of satisfaction expressed by numbers. Theobjective of this study is to evaluate the parameters of quality oflife of 23 patients who underwent surgery for anterior cruciateligament reconstruction. Methods: We adopted SF-36, a generichealth-related evaluation questionnaire, to obtain informationregarding several aspects of patients’ health conditions, and theLysholm questionnaire, specific to evaluate the symptoms andfunction of the knee. The questionnaires were applied at two stagesof the treatment: pre- and postoperatively (after the rehabilitationprogram. Results: Before surgery, the Lysholm questionnairepresented the following results: excellent in 4% of the cases, goodin 22%, fair in 22%, and poor in 52%. After surgery (Lysholm e SF-36 the correlation level was approximately 44% (p = 0.041.Discussion: The correlation between the Lysholm and the SF-36questionnaires showed the following: the lower the level of pain,the higher the Lysholm score. The high scores presented by theLysholm questionnaire are directly proportional to physical andemotional aspects, and to functional capacity. Conclusion:Analysis of both questionnaires, as well as of their correlation,showed some improvement in patients´ quality of life. We werealso able to demonstrate the importance and usefulness of applyingthe two questionnaires at three different moments: before, duringand after physiotherapeutic intervention.

    Settings and Design: A prospective study from September 2005 to March 2008 in a tertiary care teaching hospital. Materials and Methods: Seventeen patients with long or multiple strictures of the anterior urethra were treated by a dorsolateral free buccal mucosa graft. The pendulous urethra was accessed by penile eversion through the perineal wound. The urethra was not separated from the corporal bodies on one side and was only mobilized from the midline on the ventral aspect to beyond the midline on the dorsal aspect. The urethra was opened in the dorsal midline over the stricture. The buccal mucosa graft was secured on the ventral tunica of the corporal bodies. Statistical Analysis Used: Mean and median. Results: After a follow-up of 12-30 months, one recurrence developed and 1 patient needed an internal urethrotomy. Conclusions: A unilateral urethral mobilization approach for dorsolateral free graft urethroplasty is feasible for panurethral strictures of any length with good short-term success.

    Full Text Available Study Design: Fractures of the atlas are classified based on the fracture location and associated ligamentous injury. Among patients with atlas fractures treated using external immobilization, nonunion of the fracture could be seen. Objective: Ideally, treatment strategy for an unstable atlas fracture would involve limited fixation to maintain the fracture fragments in a reduced position without restricting the range of motion (ROM of the atlantoaxial and atlantooccipital joints. Summary of Background Data: Such a result can be established using either transoral limited internal fixation or limited posterior lateral mass fixation. However, due to high infection risk and technical difficulty, posterior approaches are preferred but none of these techniques can fully address anterior 1/4 atlas fractures such as in this case. Materials and Methods: A novel open and direct technique in which a unilateral lag screw was placed to reduce and stabilize a progressively widening isolated right-sided anterior 1/4 single fracture of C 1 that was initially treated with a rigid cervical collar is described. Results: Radiological studies made after the surgery showed no implant failure, good cervical alignment, and good reduction with fusion of C 1 . Conclusions: It is suggested that isolated C 1 fractures can be surgically reduced and immobilized using a lateral compression screw to allow union and maintain both C 1-0 and C 1-2 motions, and in our knowledge this is the first description of the use of a lag screw to achieve reduction of distracted anterior 1/4 fracture fragments of the C1 from a posterior approach. This technique has the potential to become a valuable adjunct to the surgeon′s armamentarium, in our opinion, only for fractures with distracted or comminuted fragments whose alignment would not be expected to significantly change with classical lateral mass screw reduction.

    Anomalies of the anterior belly of the digastric muscle (DM) are uncommon. We present a case of hypoplasia of the anterior belly of the left DM with hypertrophy of the anterior belly of the contralateral DM. The importance of recognizing this finding is to differentiate hypoplasia of the anterior belly of the DM from denervation atrophy, and not to confuse contralateral hypertrophy with a submental mass or lymphadenopathy. In denervation atrophy of the anterior belly of the DM, associated atrophy of the ipsilateral mylohyoid muscle is present. Hypertrophy of the anterior belly of the contralateral DM can be differentiated from a submental mass or lymphadenopathy by recognizing its isodensity on computed tomography and isointensity on magnetic resonance imaging to other muscles, without abnormal contrast enhancement.

    To define the number and distribution of osteophytes (OPs) in bilateral knee MRI (magnetic resonance imaging) of patients with unilateral anterior cruciate ligament (ACL) rupture. Bilateral knee MRIs of 20 patients with unilateral ACL rupture and reconstruction were retrospectively analyzed for OPs. OPs were graded following the KOSS (knee OA scoring system) classification and their compartmental distribution was assessed following the WORMS (Whole-Organ Magnetic Resonance Imaging Score) classification. All examined knees revealed OPs. Knees with ACL rupture showed significant (p < 0.001) higher total numbers of OPs (mean 11.6; SD {+-} 4.4) than knees with intact ACL (mean 5.1; SD {+-} 2.3). Knees with ACL rupture showed increased OP formation in all knee compartments with predominance of marginal OPs in the lateral femorotibial compartment especially on the tibia. Our results show that after knee injury with ACL rupture and reconstruction, all knee compartments were involved in post-traumatic increase of OP formation. The most affected compartment was the lateral femorotibial compartment on the tibial side. (orig.)

    2018-01-01

    Full Text Available Purpose: The anterior cingulate cortex (ACC has been suggested to be involved in chronic subjective tinnitus. Tinnitus may arise from aberrant functional coupling between the ACC and cerebral cortex. To explore this hypothesis, we used resting-state functional magnetic resonance imaging (fMRI to illuminate the functional connectivity (FC network of the ACC subregions in chronic tinnitus patients.Methods: Resting-state fMRI scans were obtained from 31 chronic right-sided tinnitus patients and 40 healthy controls (age, sex, and education well-matched in this study. Rostral ACC and dorsal ACC were selected as seed regions to investigate the intrinsic FC with the whole brain. The resulting FC patterns were correlated with clinical tinnitus characteristics including the tinnitus duration and tinnitus distress.Results: Compared with healthy controls, chronic tinnitus patients showed disrupted FC patterns of ACC within several brain networks, including the auditory cortex, prefrontal cortex, visual cortex, and default mode network (DMN. The Tinnitus Handicap Questionnaires (THQ scores showed positive correlations with increased FC between the rostral ACC and left precuneus (r = 0.507, p = 0.008 as well as the dorsal ACC and right inferior parietal lobe (r = 0.447, p = 0.022.Conclusions: Chronic tinnitus patients have abnormal FC networks originating from ACC to other selected brain regions that are associated with specific tinnitus characteristics. Resting-state ACC-cortical FC disturbances may play an important role in neuropathological features underlying chronic tinnitus.

    Full Text Available Objectives. The objective of this study is to compare the impact of early and late reconstruction of complete unilateral cleft lip and palate on the growth and development of the front of the dentoalveolar arch. Methods. This study was carried out in the years 2012–2015 at the Clinic of Plastic, Reconstructive and Aesthetic Surgery in Banska Bystrica. Infants with unilateral complete cleft lip and palate were divided into 2 groups according to the timing of lip reconstruction. Group A consisted of infants with early lip reconstruction–realised in the first 14 days of life. Group B consisted of infants with later lip reconstruction–realised in the third month of age. Maxillary dental casts were obtained for each child in four periods–in the first 14 days of life, in the third month, in the sixth month and in the age of one year. These were followed by the identification, measurement and evaluation of anthropometric parameters. Results. Significant differences were occurred after the reconstruction of the lips in linear and angle measurements between infants in the A and B groups. Conclusion. The early surgical reconstruction of the lips in the first 14 days of life has a positive effect on the growth and development of the anterior segment of the dentoalveolar arch. Early lip reconstruction forms a continuous pressure on the frontal segment, resulting in the earlier remedy of anatomical properties and creates appropriate conditions for the best development of this area.

    The isolated aplasia of the serratus anterior muscle with winging of scapula is very rare, and only a few cases are reported. Here, we present a case of a 30-year-old Korean male who initially presented with a left flank pain. His physical exam did not show any significant finding in his right shoulder. However, his chest radiograph showed absence of right serratus anterior muscle and slightly elevated and medially rotated right scapula. Subsequent CT scan showed the right serratus anterior muscle aplasia and medial winging of the right scapula. This case is unique in two aspects. First, the combination of abnormalities is different from the typical congenital abnormalities involving shoulder girdle, such as Sprengel deformity or Poland syndrome. Secondly, this was incidentally diagnosed with chest radiograph, without clinical impression. Careful reading of chest radiograph can help the radiologists to detect such clinically silent abnormalities.

    The presence of pain during movement typically results in changes in technique. However, the physical properties of water, such as flotation, means that water-based exercise may not only reduce compensatory movement patterns but also allow pain sufferers to complete exercises that they are unable to perform on land. The purpose of this study was to assess bilateral kinematics during double-leg squats and single-leg squats on land and in water in individuals with unilateral anterior knee pain. A secondary aim was to quantify bilateral asymmetry in both environments in affected and unaffected individuals using a symmetry index. Twenty individuals with unilateral knee pain and twenty healthy, matched controls performed body weight double- and single-leg squats in both environments while inertial sensors (100 Hz) recorded trunk and lower body kinematics. Repeated-measures statistics tested for environmental effects on movement depths and peak angles within the anterior knee pain group. Differences in their inter-limb symmetry in each environments was compared to the control group using analysis of variance tests. Water immersion allowed for greater movement depths during both exercises (double-leg squat: +7 cm, p  = 0.032, single-leg squat: +9 cm, p  = 0.002) for the knee pain group. The double-leg squat was symmetrical on land but water immersion revealed asymmetries in the lower body frontal plane movements. The single-leg squat revealed decreased hip flexion and frontal plane shank motions on the affected limb in both environments. Water immersion also affected the degree of lower limb asymmetry in both groups, with differences also showing between groups. Individuals with anterior knee pain achieved increased squat depth during both exercises whilst in water. Kinematic differences between the affected and unaffected limbs were often increased in water. Individuals with unilateral anterior knee pain appear to utilise different kinematics in the affected

    To assess anterior segment optical coherence tomographic measurements of patients after acute unilateral primary angle closure (APAC) compared with those of normal subjects. The clinical observational study included 41 hospital-based patients after unilateral APAC, their unaffected contralateral eyes, and 205 subjects. These were selected from the population-based Beijing Eye Study, and were matched with the APAC group for age, gender, and refractive error. All study participants underwent slit-lamp adapted optical coherence tomography (OCT). Compared with the unaffected contralateral eyes, eyes with APAC had a significantly shallower anterior chamber (P APAC and the unaffected contralateral eyes both showed more shallow anterior chambers (P APAC group, the anterior chamber angle was closed in three or more quadrants. Anterior segment OCT measurements show significant differences between eyes with APAC, contralateral eyes at risk for APAC, and normal eyes. This may open possibilities for a semi-automatic assessment of subjects at risk for APAC by anterior segment OCT. The anterior chamber angle was closed most often in the nasal quadrant, and, in APAC, the angle was closed in three or more quadrants.

    A case of left anterior and middle cerebral arterial occlusion with angiographic features similar to Moyamoya disease was reported. IMP SPECT of the patient revealed the success of bypass surgery clearly. The patient complained of transient right hemiparesis with aphasia 4 times. The cerebral arteriography disclosed occlusions of left anterior and middle cerebral arteries at their proximal portions. Right internal carotid and its branches were normal. I-123 IMP SPECT study showed hypoperfusion in left temporal lobe, basal ganglia with incomplete reperfusion on the delayed (4 hours after injection) SPECT images. After the superficial temporal-middle cerebral artery anastomosis, I-123 IMP SPECT showed improvement of the brain blood flow. I-123 IMP SPECT was very useful in detecting the ischemic areas and evaluating the revascularizing surgery in this case. (author)

    Persistent hyperplastic primary vitreous (PHPV) is an ocular developmental disorder resulting from incomplete apoptosis of the embryonic hyaloid vasculature. Unilateral PHPV is traditionally associated with a poor prognosis because of the challenges associated with managing progressive anisometropic amblyopia. We report a child with unilateral PHPV who underwent cataract extraction, primary posterior capsulotomy with anterior vitrectomy and intraocular lens implantation followed by combined trabeculectomy/trabeculotomy within the first 8 weeks of life. Intensive optometric and orthoptic input was required for many years to manage the increasing anisometropic amblyopia with final visual acuity of 20/40 unaided in the affected eye and without evidence of glaucomatous optic neuropathy. This case illustrates the excellent visual outcome possible in a child with complex, unilateral PHPV using an intensive management approach comprising: early surgical intervention for congenital cataract and secondary glaucoma, meticulous monitoring of refraction, visual acuity and intraocular pressure and motivated parents who engaged in the management. 2015 BMJ Publishing Group Ltd.

    Joint injuries and subsequent osteoarthritis (OA) are the leading causes of chronic joint disease. In this work, we explore the possibility of applying magnetic resonance spectroscopy-based metabolomics to detect host responses to an anterior cruciate ligament (ACL) reconstruction injury in synovial fluid in an ovine model. Using multivariate statistical analysis, we were able to distinguish post-injury joint samples (ACL and sham surgery) from the uninjured control samples, and as well the ACL surgical samples from sham surgery. In all samples there were 65 metabolites quantified, of which six could be suggested as biomarkers for early post-injury degenerative changes in the knee joints: isobutyrate, glucose, hydroxyproline, asparagine, serine, and uridine. Our results raise a cautionary note indicating that surgical interventions into the knee can result in metabolic alterations that need to be distinguished from those caused by the early onset of OA. Our findings illustrate the potential application of metabolomics as a diagnostic and prognostic tool for detection of injuries to the knee joint. The ability to detect a unique pattern of metabolic changes in the synovial fluid of sheep offers the possibility of extending the approach to precision medicine protocols in patient populations in the future. © 2014 Orthopaedic Research Society.

    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 = 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

    We retrospectively analyzed 8 patients with intractable medial temporal lobe epilepsy (MTLE) who underwent the anterior temporal lobectomy with hippocampectomy (ATL) without invasive examinations such as chronic subdural electrode recording. Five patients had a history of febrile convulsion. While all 8 patients had oral automatism, automatism of ipsilateral limbs with dystonic posture of contralateral limbs was demonstrated in 2 patients. Bilateral temporal paroxysmal activities on interictal EEG was observed in 4 patients and all patients had clear ictal onset zone on unilateral anterior temporal region. MRI demonstrated unilateral hippocampal sclerosis in 5 cases. Interictal FDG-PET depicted hypometabolism of the unilateral temporal lobe in all cases, however, ECD-SPECT failed to reveal the hypoperfusion of the unilateral temporal lobe in a case. Postoperatively, 7 cases became seizure free, and one had rare seizure. Non-invasive examinations, especially ictal EEG and concordant FDG-PET findings, in patients with oral automatism in seizure semiology, successfully select patients with MTLE for ATL. (author)

    Fornical injury in transforaminal approach is well known. Its injury in the anterior interhemispheric approach (AIA) has been rarely highlighted. We report 2 cases with a large suprasellar tumor who underwent AIA. Postoperative heavily T2 weighted reversed (T2R) MR images demonstrated its unilateral injury. The clinical significance of symptom-free fornical injury after AIA is discussed. Cases 1 and 2 were a 15 year-old girl with a meningioma and a 49-year-old woman with a craniopharyngioma, respectively. They underwent AIA. Postoperative T2R images revealed unilateral fornical crus atrophy. They did not present associated memory deficits. Case 1 had the injury of both fornical column and anterior commissure. They were speculatively torn by intra-operative lateral retraction of the frontal lobes. Case 2 had unilateral atrophy of the mammillary body and postcommissural fornix, which were probably caused by ischemic damage related to surgical manipulation, since case 2 had an associated anterior thalamic infarct. During the Operation for large suprasellar tumors, excessive laterally directed brain retraction should be avoided, since such manipulation may easily tear the overstretched anterior commissure and fornical column. Once we notice or suspect fornical injury an MR studies in cases of re-operation, we have to choose a surgical approach and operative manipulation to preserve an intact fornix. The MR evaluation of fornix should be included in the peri-operative radiological assessment, since patients with unilateral fornical injury were free of memory disturbance, and T2R imaging is a useful MR sequence for depicting the anatomy related to the fornix.

    During a routine dissection of an adult embalmed male cadaver for educational purpose in the department of anatomy at AIIMS, New Delhi, India, a rare unilateral variation of extensor digitorum longus (EDL) was found which is a muscle of anterior compartment of the leg. There was a split tendon of EDL muscle in the anterior compartment of left leg which became a common tendon in front of the ankle joint. This common tendon of EDL muscle again divided into four slips and were inserted in to the lateral four toes. In the upper part of the leg, the anterior tibial vessel and deep fibular nerve lie between the EDL and tibialis anterior. Knowledge of this type of anomaly is useful in diagnosis and treatment of compartmental syndrome. One of the tendon from the split tendon of EDL muscle can be used as a graft in tendon replacement surgeries. The split tendon may also be capable for some precise movements of the toes.

    The purpose of this study was to compare the triple-bundle (TB) anterior cruciate ligament (ACL) reconstruction with the double-bundle (DB) ACL reconstruction in immediate postoperative anterior knee stability. This study involved 133 patients who had undergone the anatomic ACL reconstruction with autogenous hamstring tendon unilaterally. Then 83 patients (mean age, 28.8 years) underwent the DB between November 2004 and December 2005, and 50 patients (mean age, 29.6 years) underwent the TB ACL reconstruction between January and December 2006. The 2 femoral tunnels were created in the ideal ACL attachment area, whereas 2 tibial tunnels for the DB and 3 tunnels for the TB were created in the ACL footprint. The 2 doubled tendon grafts were fixed with EndoButton-CL (Smith & Nephew Endoscopy, Andover, MA) on the femur. The grafts were fixed to the tibia using a Double Spike Plate and a screw under the total initial tension of 20 N at 20° of flexion, after meticulous in situ pretensioning using a tensioning boot. Then immediate postoperative anterior knee laxity in response to 89 N of anterior load was measured by one experienced examiner (T.M.) with the KT-2000 Knee Arthrometer (MEDmedtric, San Diego, CA) under general anesthesia at 30° of knee flexion with muscle relaxants. The measured anterior laxity was 3.4 ± 1.2 mm in the DB and 2.5 ± 0.7 mm in the TB ACL reconstruction, a statistically significant difference. The side-to-side difference of the laxity was -3.2 ± 1.6 mm in the DB and -4.2 ± 2.0 mm in the TB, again a significant difference. TB ACL reconstruction resulted in better immediate postoperative anterior knee stability than DB ACL reconstruction under 89 N of anterior tibial load (P = .031).

    The anterior approach for C7-T1 disc herniation may be challenging because of obstruction by the manubrium and the narrow operative field. This study aimed to investigate the clinical and neurological outcomes of anterior approach for C7-T1 disc herniation. We retrospectively evaluated 13 patients who underwent the anterior approach for C7-T1 disc herniation by a single surgeon within a period of 11 years (2003-2014). The minimum follow-up duration was 6 months. We describe the clinical presentation, radiographic findings, neurological outcome, and related complications. Of 372 patients with single-level anterior discectomy and fusion or artificial disc replacement for cervical disc herniation, 13 (3.5%) had C7-T1 disc herniation. The main clinical presentation was unilateral motor weakness in intrinsic hand muscles (11 patients), along with numbness, pain, and tingling sensation that radiate down the arm to the little finger. Most of the patients improved after surgery via the anterior approach. Ten patients underwent successful anterior discectomy and fusion by the standard supramanubrial Smith-Robinson approach, but 2 needed additional manubriotomy and sternotomy. In 1 patient, we performed surgery at a wrong level because the correct level was difficult to identify intraoperatively. Two patients had transient vocal dysfunction, but none had major complications related to injuries of the great vessels such as the thoracic duct or esophagus. For patients who require direct anterior decompression for C7-T1 disc herniation, the anterior approach is relatively feasible. However, care should be taken to overcome physical constraints by the manubrium and slope.

    Postnatal growth is influenced by genetic and environmental factors. Nasal obstruction during growth alters the electromyographic activity of orofacial muscles. The facial primary motor area represents muscles of the tongue and jaw, which are essential in regulating orofacial motor functions, including chewing and jaw opening. This study aimed to evaluate the effect of chronic unilateral nasal obstruction during growth on the motor representations within the face primary motor cortex (M1). Seventy-two 6-day-old male Wistar rats were randomly divided into control ( n = 36) and experimental ( n = 36) groups. Rats in the experimental group underwent unilateral nasal obstruction after cauterization of the external nostril at 8 days of age. Intracortical microstimulation (ICMS) mapping was performed when the rats were 5, 7, 9, and 11 wk old in control and experimental groups ( n = 9 per group per time point). Repeated-measures multivariate ANOVA was used for intergroup and intragroup statistical comparisons. In the control and experimental groups, the total number of positive ICMS sites for the genioglossus and anterior digastric muscles was significantly higher at 5, 7, and 9 wk, but there was no significant difference between 9 and 11 wk of age. Moreover, the total number of positive ICMS sites was significantly smaller in the experimental group than in the control at each age. It is possible that nasal obstruction induced the initial changes in orofacial motor behavior in response to the altered respiratory pattern, which eventually contributed to face-M1 neuroplasticity. NEW & NOTEWORTHY Unilateral nasal obstruction in rats during growth periods induced changes in arterial oxygen saturation (SpO 2 ) and altered development of the motor representation within the face primary cortex. Unilateral nasal obstruction occurring during growth periods may greatly affect not only respiratory function but also craniofacial function in rats. Nasal obstruction should be treated

    Retrospective clinical study. The purpose of this study was to determine what percentage of patients who underwent nonoperative management of unilateral non-displaced or minimally displaced facet fractures progressed radiographically and to determine what percentage of patients required surgical intervention and to identify risk factors for failure of conservative management. According to most commonly used classification systems, unilateral, non-and minimally displaced facet fractures are be amendable to nonoperative management. A retrospective review of the Trauma Registry of a Level I trauma center was performed to identify all patients diagnosed with a non- or minimally displaced unilateral facet fracture which was managed nonoperatively. Several demographic variables and clinical outcomes were recorded. Using computed tomography scanning and plain radiographs, fracture pattern, listhesis, displacement, angle and percentage of the facet that included the fracture were determined. Radiographic progression was defined as the occurrence of listhesis of more than 10% of the anterior-posterior dimensions of the inferior vertebral body during radiographic follow-up. Failure of conservative management was defined as a patient requiring surgical intervention after initially being managed nonoperatively. Seventy-four patients were included. Fifteen patients (20%) progressed radiographically. However, only 2 developed radicular symptoms and none developed myelopathy or other catastrophic cord related symptoms. Seven patients (9%) underwent surgery. Indications for surgery included significant radiographic progression and/or radicular symptoms. Risk factors for failure of conservative management included presence of radiculopathy at the time of presentation, a higher body mass index, increased Injury Severity Score, greater initial fracture displacement and more than 2 mm of listhesis. Patients with non-displaced or minimally displaced facet fractures who do not have

    Between 1987 and 1992, 30 infants aged 1.4-13 months (mean 7.3 months) underwent unilateral lambdoid strip craniectomy at the Children's Hospital of Buffalo for occipital plagiocephaly. Males outnumbered females (22:8) and right-sided occipital flattening was significantly more common than left-sided flattening (25:5). The deformity was noticed at an average age of 3.2 months; 16% of the infants had an asymmetry at birth. Positional preferences (a distinct tendency to lie preferentially on the back, in most cases with the head turned to the ipsilateral side) were described in 79% of infants for whom this information was available, and torticollis was present in 10%. Pre-and post-operative CT scans were analyzed using several morphometric measurements. Asymmetries were measured between the flattened and contralateral sides, both posteriorly and anteriorly, using a translucent grid placed over the CT slice showing maximum asymmetry. The average maximum asymmetry between the flattened and contralateral sides was 24% posteriorly and 16% anteriorly. Significant improvements were seen postoperatively, with both anterior and posterior asymmetries improving by an average of one third (p < 0.05). However, when compared with CT scans from a control group of infants without synostosis, the operated group showed persistent and significant asymmetries postoperatively. The morphometric measurements described allow an objective and reproducible means of assessing the results of various treatments for this disorders. The improvements following unilateral lambdoid craniectomy are difficult to interpret in isolation; we suggest that future efforts be directed toward similarly assessing the results of both nonoperative treatments such as positional changes and molding helmets, and more aggressive surgical treatments that have been advocated for this disorders.

    Three mongrel dogs, aged 10 months (case 1), 14 months (case 2) and 7.5 years (case 3), were presented because of ophthalmologic disorders of 4 months, 6 months and 7 years duration, respectively. All three dogs were offspring of stray dogs from Hungary and Serbia and had positive serum antibody titres against Encephalitozoon (E.) cuniculi. The two young dogs showed unilateral, the older dog bilateral chronic anterior uveitis with posterior synechia and focal anterior cortical cataract. The fundi that could be evaluated developed focal tapetal hyporeflective lesions in the course of the disease. Dogs 1 and 2 underwent removal of the lens via phacoemulsification. PCR of the lens material was positive for E. cuniculi strains IV and II, respectively. In dog 2 findings suggestive of microsporidia were detected underneath the anterior lens capsule by immunohistochemical staining. In all cases medical treatment consisted of systemic fenbendazole, prednisolone, and topical anti-inflammatory drugs, and additional brinzolamid/timolol for dog 3. For the time being all cases (follow up 23 months, 6 months and 3 months, respectively) are still on topical anti-inflammatory therapy. It is concluded that E. cuniculi infections can cause cataract and chorioretinal lesions in dogs.

    To compare the maxillofacial morphology in the early mixed dentition phase between two patient groups with unilateral cleft lip, alveolus, and palate who underwent different types of palatoplasty. Cross-sectional study. An institutional study. Seventy-one patients with unilateral cleft lip and palate (UCLP) treated at Osaka University Dental Hospital, Japan, were divided into two groups: 33 patients were treated by early two-stage palatoplasty by the modified Furlow Technique (ETS), and 38 patients were treated by one-stage Wardill-Kilner push-back palatoplasty (PB). Intergroup comparisons were performed. The dental, skeletal, and soft-tissue features were evaluated. For intergroup comparisons, Mann-Whitney U test was used for the statistical analyses. No significant differences existed between the ETS and PB groups regarding the skeletal features except for the mandibular ridge height. Meanwhile, the upper central incisor and upper lip of the ETS group showed a more anterior position than those in the PB group. Early two-stage Furlow palatoplasty leads to more protruded upper lip, providing more anteriorly positioned upper incisors compared with PB, at least at the early mixed dentition stage.

    Primary palmar hyperhidrosis that arises mostly during puberty and early adolescence has a tremendous impact on the quality of life in patients. This study aimed to investigate the effectiveness of unilateral video-assisted thoracic sympathectomy for dominant hand in these patients. From July 2010 to June 2013, 52 patients with primary palmar hyperhidrosis underwent unilateral video-assisted thoracoscopic sympathectomy for dominant hand. We analyzed the outcomes regarding the resolution of symptoms, occurrence of complications, recurrence rate, and compensatory hyperhidrosis, and need of operation for opposite side. All patients were followed up from 6 to 42 months. Palmar hyperhidrosis was completely alleviated and absolute dryness was achieved in all patients at the same hand after the operation. Palmar hyperhidrosis in the opposite hand was cured to a complete dryness in 24 (46.15%) patients. No change happened in the opposite hand in 22 (42.3%) patients, but an increase was seen in 6 (11.53%) patients. Only seven (13.46%) patients needed to undergo contralateral sympathectomy. Compensatory hyperhidrosis occurred in 13 patients (25%) after unilateral sympathectomy. Another five patients (totally 18, 34.6%) were involved with compensatory hyperhidrosis after contralateral sympathectomy. It was mainly on the trunk in all 18 patients. Unilateral dominant side thoracoscopic sympathectomy for patients with primary palmar hyperhidrosis is an effective, safe, and minimally invasive procedure. Only a small number of patients will eventually require a contralateral sympathectomy in nondominant hand. Georg Thieme Verlag KG Stuttgart · New York.

    The objective of this study was to develop and evaluate the voice outcomes of an approach to arytenoid adduction (AA) for unilateral vocal cord paralysis through fenestration of the thyroid ala. Thirty-two patients with unilateral vocal cord paralysis underwent laryngoplasty using an approach to AA performed through fenestration of the thyroid ala combined with type I thyroplasty. Thirty-two patients with unilateral vocal cord paralysis were treated between October 2004 and February 2008. In all cases, maximum phonation time (MPT) and mean airflow rate (MFR) were measured before and after the operation. The voices were analyzed using shimmer and jitter. Two surgical windows were made in the lower part of the thyroid ala. The anterior one was for typical type I thyroplasty and the posterior one was for arytenoid adduction (AA). The locations of the two windows were determined based on three-dimensional computer tomography (3DCT) data. AA was performed by muscular process through the posterior window without releasing the cricothyroid joint. The operations were performed under local anesthesia with sedation. Vocal cord medialization was confirmed endoscopically during the operation. Twenty-nine of the 32 patients achieved an MPT of over 10 s after surgery. The other 3 cases, whose MPTs were 9 s after the operation, had low breathing capacity because of lung disease and normal side vocal cord sulcus. The MFRs, which ranged from 236 to 1908 ml/s before the operation, improved to under 200 ml/s except in 3 patients, whose MFRs were 210 ml/s, 214 ml/s and 216 ml/s. Jitter and shimmer improved significantly after the operation. Perceptual evaluation using the GRBAS scale also improved significantly. Our new procedure simplified the combination of AA and type I thyroplasty because the two treatments can be performed in the same operating field, obtaining good voice improvement. Determination of the surgical approach using 3DCT and endoscopic vocal cord observation may

    Full Text Available Most of the cervical spine injuries in the pediatric population are typically seen in the upper cervical region. Unilateral cervical facet dislocation (UFD in subaxial region is a rare injury in pediatric population. In this paper, a rare case of delayed locked UFD in a 9-year-old boy with rare injury mechanism treated surgically is reported. Clinical and radiological findings were described. The patient with C6-7 UFD without neurologic deficit was underwent open reduction and internal fixation via anterior and posterior combined approaches. Significant improvement of pain and free motion in cervical spine was obtained. There was no complication during the follow up. Only three case reports presented about the lower cervical spine injury with UFD under the age of 10 were found in the literature.

    Full Text Available Afatinib is a second-generation epidermal growth factor receptor (EGFR inhibitor that has been shown to be effective against EGFR-mutated non-small cell lung cancer (NSCLC resistant to conventional EGFR inhibitors such as gefitinib and erlotinib. Although ocular side effects of gefitinib and erlotinib have been reported, those for afatinib have yet to be definitively established. This report presents details on the first case of unilateral iridocyclitis associated with the side effects of afatinib therapy. A 75-year-old Japanese male ex-smoker with EGFR-mutated NSCLC underwent afatinib therapy for multiple metastases. At 2 weeks, bilateral conjunctivitis developed. Topical medication and a 1-week afatinib washout period resulted in the improvement of the conjunctivitis. However, 3 days after the resumption of afatinib, the patient developed unilateral granulomatous anterior uveitis in his right eye. Best-corrected visual acuity (BCVA measurement indicated a decimal visual acuity of 0.2, while the slit-lamp findings were characterized by granulomatous inflammation, keratic precipitates, Koeppe nodules and posterior synechiae. There was no evidence suggesting other intraocular inflammatory disease or metastatic tumor. The left eye was intact. The use of topical medication including steroids and a washout of afatinib resulted in a gradual subsiding of the anterior uveitis. After resolution of the anterior uveitis, oral afatinib was resumed. BCVA of the right eye finally recovered to a decimal acuity of 1.0. Ophthalmologists should be aware of the possibility that side effects associated with afatinib could cause granulomatous anterior uveitis.

    To evaluate the prevalence of fistulas after palate repair and analyze their location and association with possible causal factors. Retrospective analysis of patient records and evaluation of preoperative initial photographs. Tertiary craniofacial center. Five hundred eighty-nine individuals with complete unilateral cleft lip and palate that underwent palate repair at the age of 12 to 36 months by the von Langenbeck technique, in a single stage, by the plastic surgery team of the hospital, from January 2003 to July 2007. The cleft width was visually classified by a single examiner as narrow, regular, or wide. The following regions of the palate were considered for the location: anterior, medium, transition (between hard and soft palate), and soft palate. Descriptive statistics and analysis of association between the occurrence of fistula and the different parameters were evaluated. Palatal fistulas were observed in 27% of the sample, with a greater proportion at the anterior region (37.11%). The chi-square statistical test revealed statistically significant association (P ≤ .05) between the fistulas and initial cleft width (P = .0003), intraoperative problems (P = .0037), and postoperative problems (P = .00002). The prevalence of palatal fistula was similar to mean values reported in the literature. Analysis of causal factors showed a positive association between palatal fistulas with wide and regular initial cleft width and intraoperative and postoperative problems. The anterior region presented the greatest occurrence of fistulas.

    Full Text Available This study assessed the prevalence and causes of unilateral visual impairment in the urban population of Hyderabad city as part of the Andhra Pradesh Eye Disease Study. Stratified, random, cluster, systematic sampling was used to select 2,954 subjects from 24 clusters representative of the population of Hyderabad. Eligible subjects underwent detailed eye examination including logMAR visual acuity, refraction, slitlamp biomicroscopy, applanation tonometry, gonioscopy, dilatation, cataract grading, and stereoscopic evaluation of fundus. Automated threshold visual fields and slitlamp and fundus photography were done when indicated by standardised criteria. Unilateral visual impairment was defined as presenting distance visual acuity <6/18 in the worse eye and ≥6/12 in the better eye, which was further divided into unilateral blindness (visual acuity <6/60 in the worse eye and unilateral moderate visual impairment (visual acuity <6/18-6/60 in the worse eye. A total of 2,522 subjects (85.4% of eligible, including 1,399 ≥30 years old, participated in the study. In addition to the 1% blindness and 7.2% moderate visual impairment (based on bilateral visual impairment criteria reported earlier in this sample, 139 subjects had unilateral visual impairment, an age-gender-adjusted prevalence of 3.8% (95% confidence interval 2.7-4.9%. The major causes of this visual impairment 39.9% were refractive error (42.9%, cataract (14.4%, corneal disease (11.5%, and retinal disease (11.2%. Of this unilateral visual impairment was blindness. The major causes of unilateral blindness were corneal disease (23.2%, cataract (22.5%, retinal disease (18%, and optic atrophy (12.9%. On the other hand, the predominant cause of unilateral moderate visual impairment was refractive error (67% followed by cataract (9%. Of the total unilateral visual impairment, 34.3% was present in those <30 years old and 36.2% in those 30-49 years old. Unilateral visual

    Goodall, W A; Greer, A C; Martin, N

    2017-01-27

    Removable partial dentures (RPDs) are widely used to replace missing teeth in order to restore both function and aesthetics for the partially dentate patient. Conventional RPD design is frequently bilateral and consists of a major connector that bridges both sides of the arch. Some patients cannot and will not tolerate such an extensive appliance. For these patients, bridgework may not be a predictable option and it is not always possible to provide implant-retained restorations. This article presents unilateral RPDs as a potential treatment modality for such patients and explores indications and contraindications for their use, including factors relating to patient history, clinical presentation and patient wishes. Through case examples, design, material and fabrication considerations will be discussed. While their use is not widespread, there are a number of patients who benefit from the provision of unilateral RPDs. They are a useful treatment to have in the clinician's armamentarium, but a highly-skilled dental team and a specific patient presentation is required in order for them to be a reasonable and predictable prosthetic option.

    2014-01-01

    Full Text Available Cushing’s syndrome (CS may lead to severe maternal and fetal morbidities and even mortalities in pregnancy. However, pregnancy complicates the diagnosis and treatment of CS. This study describes a 26-year-old pregnant woman admitted with hypertension-induced headache. Hormonal analyses performed due to her cushingoid phenotype revealed a diagnosis of adrenocorticotropic hormone- (ACTH- independent CS. MRI showed a 3.5 cm adenoma in her right adrenal gland. After preoperative metyrapone therapy, she underwent a successful unilateral laparoscopic adrenalectomy at 14-week gestation. Although she had a temporary postoperative adrenal insufficiency, hormonal analyses showed that she has been in remission since delivery. Findings in this patient, as well as those in previous patients, indicate that pregnancy is not an absolute contraindication for laparoscopic adrenalectomy. Rather, such surgery should be considered a safe and efficient treatment method for pregnant women with cortisol-secreting adrenal adenomas.

    The diagnosis of cerebral venous sinus thrombosis still remains a real challenge. Seizure, unusual headache with sudden onset, unexplained persistently unilateral vascular headache and neurologic deficit-which is difficult to be attributed to a vascular territory are some of the suggestive symptoms. An isolated sixth nerve palsy is discussed as a rare presentation for cerebral venous thrombosis. Following the extensive investigation to rule out other possible diagnoses, magnetic resonance venogram revealed the final etiology of sixth nerve palsy that was ipsilateral left transverse sinus thrombosis; therefore, anticoagulant treatment with low molecular weight heparin was administered. Rapid and accurate diagnosis and treatment cause to achieve excellent outcomes for most patients. Considering different clinical features, risk factors and high index of suspicion are helpful to reach the diagnosis. Copyright © 2016 Elsevier Inc. All rights reserved.

  16. Unilateral pulmonary artery agenesis: An unusual cause of unilateral ARDS

    Directory of Open Access Journals (Sweden)

    Lakshmi Saladi, MD

    Full Text Available Unilateral pulmonary artery agenesis (UPAA is a rare malformation that can present as an isolated anomaly or may be associated with certain congenital cardiac anomalies, such as tetralogy of Fallot, atrial septal defect, coarctation of aorta, right aortic arch, truncus arteriosus and pulmonary atresia. Clinical presentation is non-specific which makes the diagnosis elusive; chronic dyspnea, hemoptysis or recurrent infections are the most common manifestations. Patients may remain asymptomatic until adulthood. There is no definitive treatment for patients with UPAA. Acute respiratory distress syndrome (ARDS is usually a bilateral disease, unilateral ARDS has been described after lung resection or trauma. We present a case of a 39 year-old woman who developed unilateral ARDS and was later diagnosed with isolated UPAA.

    2015-02-01

    Full Text Available AIM: To evaluate the outcome after surgery for unilateral superior oblique (SO palsy in Chinese. METHODS: The medical records of 39 patients that underwent surgery for unilateral SO palsy between January 2003 and December 2012 at Caritas Medical Centre, Hong Kong, were retrospectively reviewed. All surgeries were performed by a single surgeon. Pre-operative assessments for vertical deviation, cyclo-deviation, and Knapp’s classification were obtained to determine the nature and degree of surgical correction. Vertical deviation was measured at 1wk; 1, 6mo and on last follow-up day post-operatively. Cyclo-deviation was measured on last follow-up day post-operatively. RESULTS: During the 10y period, 39 subjects were recruited. The most common etiology was congenital (94.9%. Knapp’s Type III (66.7% and Type I (12.8% classifications were the most common subtypes. To treat SO palsy, the most common surgical procedures were: isolated inferior oblique (IO anteriorization (41.0%, isolated IO myectomy (10.3%, and isolated IO recession (10.3%. At 3.5±2.1y post-operatively, the vertical deviation was significantly reduced (15.1±6.2 PD versus 0.5±1.4 PD, PCONCLUSION: The majority of subjects achieved corrected vertical deviation after a single surgery although there was no improvement in cyclo-deviation. Those with over-correction of primary position deviation had greater preoperative vertical deviation and it may be related to simultaneous multiple muscle surgery.

    Congenital unilateral absence of a pulmonary artery (UAPA) is a rare anomaly. Although there are several reports regarding pregnancy in patients with unilateral absence of a pulmonary artery, there are no case reports describing anesthesia for Cesarean section in a patient with unilateral absence of a pulmonary artery. We present a patient with unilateral absence of a pulmonary artery who underwent Cesarean sections twice at the ages of 24 and 26 years under spinal anesthesia for surgery and epidural analgesia for postoperative pain relief. Both times, spinal anesthesia and epidural analgesia enabled successful anesthesia management without the development of either pulmonary hypertension or right heart failure. Spinal anesthesia combined with epidural analgesia is a useful anesthetic method for a Cesarean section in patients with unilateral absence of a pulmonary artery.

    1977-01-01

    An unusual case of twin unilateral interstitial pregnancy is described. On admission the patient was thought to have an intrauterine pregnancy of 14 weeks' gestation. Because of an irregularity in the right cornual region of the uterus, a culdocentesis was performed which returned unclotted blood. Because of this finding the patient underwent laparoscopy which revealed an unruptured right cornual pregnancy. An early diagnosis before rupture allowed for conservative surgical management and uterine conservation.

  1. Craniofacial morphology of children with complete unilateral cleft lip and palate following labioplasty and palatoplasty

    Sigit Handoko Utomo

    2012-06-01

    Full Text Available Background: A complete unilateral cleft lip and palate generally results in asymmetry of the midface. The lack of continuity in the perilabial musculature through the midline contributes to a malpositioning of the underlying osseus structures which are often underdeveloped. Purpose: The purpose of this study was to determine whether there are differences in the craniofacial morphology among children with complete unilateral cleft lip and palate following labioplasty and palatoplasty as compared with children without cleft lip and palate at the same pubertal age. Methods: A series of 14 consecutively treated subjects with complete unilateral cleft lip and palate following labioplasty and palatoplasty were compared with 14 pubertal stage-matched controls with normal craniofacial structure. Pubertal stage was determined with cervical vertebral maturation (CVM method improved by Baccetti et al, 2002. Lateral cephalograms were used for comparison. An unpaired t-test was run for 14 subjects with complete unilateral cleft lip and palate and 14 normal subjects. Results: There were significant cephalometric differences in anterior cranial base length (p = .002, cranial base length (p = .001, maxillary length (p = .000, mandibular length (p = .000, mandibular ramus height (p = .000, mandibular body length (p = .002, and upper anterior face height (p = .004. There was no significant cephalometric difference in posterior cranial base length (p = .051, lower anterior face height (p = .206, posterior face height (p = .865, growth pattern/ facial type (p = .202. Conclusion: There were craniofacial morphology differences between children with complete unilateral cleft lip and palate post labioplasty and palatoplasty and children without cleft lip and palate at the age of pubertal. Children with complete unilateral cleft lip and palate post labioplasty and palatoplasty had shorter length of the anterior cranial base, cranial base, maxilla, mandible, mandibular

    Maxillary hypoplasia is a major issue in cleft lip and palate patients, and predictable surgical maxillary advancement is required. In the present study, the changes and stability of the maxilla and soft tissue profile achieved after the application of anterior maxillary distraction osteogenesis (AMDO) using intraoral expander in unilateral cleft lip and palate and isolated cleft palate patients were investigated by comparing to the Le Fort I osteotomy (LFI) and maxillary distraction osteogenesis (DO) with rigid external distraction (RED) system.Ten patients who underwent orthognathic treatment with AMDO were examined (AMDO group). Changes in the positions of soft and hard tissue landmarks were calculated from the lateral cephalograms taken before the distraction, at the end of the distraction, and 1 year after the surgery. They were compared with the changes in 7 other unilateral cleft lip and palate patients who underwent LFI (LFI group) and 6 others who underwent DO with RED (RED group).The mean maxillary advancement of the AMDO group was similar to that of the RED group, judged by the change of point A. During DO, the AMDO group showed less clockwise rotation of mandible compared to the RED group. The soft tissue advancement of the upper lip and nose in the AMDO group was similar to that in the RED group, which was significantly larger than that in the LFI group.Our results indicate that AMDO can be surgical option to cleft lip and palate patients with less invasive but excellent improvement in both midfacial skeletal and soft tissue similar to DO-RED.

    Full Text Available The aim of this study was to detect possible differences in the EMG (electromiography activity, chewing rate (CR, cycle duration (CD and preferred chewing side (PCS between children with and without unilateral posterior crossbite. Thirty-seven children aged from 7 to 10 years were selected from the clinic of the Department of Pediatric Dentistry, Piracicaba Dental School, Brazil, and divided into two groups: unilateral posterior crossbite (UPCB group, n = 17, and normal occlusion (NOccl group, n = 20. The PCS was determined using a visual spot-checking method. The EMG activity was recorded during mastication, and two chewing sequences of 20 s were evaluated to establish each subject's CR (cycles/sec and CD. UPCB and NOccl groups did not have a PCS. The EMG activity and the cycle characteristics did not differ between the groups. The correlations between CD, CR and EMG activity were statistically significant for the masseter and anterior temporalis muscles only in the NOccl group, in which there was also a significant correlation between the EMG activity of masseter and anterior temporalis. In conclusion, these findings suggest that although children with and without UPCB presented a bilateral masticatory pattern with similar CR and CD, balanced EMG activity of masseter and anterior temporalis muscles was observed only in the NOccl group. These results indicate that in children, UPCB can alter the coordination of masticatory muscles during mastication.

    PURPOSE: We evaluated whether adult fertility potential was better when unilateral orchiopexy was done at ages 2 to 6 years or later, and we identified those at risk for infertility. MATERIALS AND METHODS: Unilateral orchiopexy was performed simultaneously with testicular biopsy in 11 patients 2...... similar fertility potentials were found in adulthood. Five of the 65 patients (7.7%, 95% confidence limits 2.5 to 17%) may experience infertility, representing 33% of both groups with less than 1% of the age matched number of spermatogonia per tubular transverse section (approximately no germ cells......) in the biopsy specimen at orchiopexy. CONCLUSIONS: Between ages 2 and 12 years the timing of unilateral orchiopexy may vary without an effect on subsequent fertility potential. When biopsy at surgery lacks germ cells, there is an approximately 33% age independent risk of subsequent infertility. Otherwise...

    An unusual case of twin unilateral interstitial pregnancy with premature rupture of membranes and leiomyomata uteri is described. A review of the literature reveals only two previous cases of this type. On admission, the patient was diagnosed as having an intrauterine pregnancy of 27 weeks' gestation, with documented premature rupture of the membranes having occurred. An ultrasound was performed revealing a fibroid uterus, an anterior placenta and an gestation. Septicemia ensued, and antibiotics plus pitocin was begun; however, no uterine response occurred. A culdocentesis revealed free intraabdominal blood. Laparotomy followed, revealing a ruptured twin interstitial pregnancy with placenta accreta and leiomyomata of the uterus.

Retrospective study with current clinical and radiographic assessments. Level I trauma center. Forty-five patients with unilateral, tibial diaphyseal fractures treated with tibial IM nailing between August 2005 and January 2009. The mean follow-up was 22.3 months (range, 12-52 months). All patients underwent tibial IM nailing using a medial paratendinous approach. Anterior knee pain based on a visual analog scale and functional outcomes based on the Tegner activity score and the modified Lysholm score. Of the 45 patients, 16 (36%) were painless (N group), 16 (36%) had mild pain (M group), and 13 (28%) had moderate to severe pain (MS group). No group differences were found with respect to age, sex, body mass index, mode of injury, or type of fracture. With regard to nail prominence, superior nail prominence was greater in the MS group than in the other two groups (P = 0.042). There were no significant differences among the three groups in terms of anterior nail prominence (P = 0.221). The nail-apex distance in the MS group was significantly greater than in the other two groups (P = 0.033), and no significant difference was found between the N and M groups. The descending order of the activities with respect to severity of knee pain was kneeling, squatting, running, and stair ascending. Visual analog scale analysis revealed that the MS group had significantly more severe pain for all eight activities examined than the M group. At latest follow-up, the Tegner activity score was significantly lower in the MS group than in the other two groups (P = 0.008), and there were statistically significant intergroup differences in the modified Lysholm score (P Anterior knee pain after tibial IM nailing using a medial paratendinous approach

    Unilateral intracranial focal nonprogressive arteriopathy is often found in children with arterial ischemic stroke. We aimed to investigate the course of unilateral intracranial arteriopathy in young adults. We searched the Utrecht Stroke Database for patients between 16 and 50 years of age diagnosed with anterior circulation arterial ischemic stroke and a nonatherosclerotic, unilateral intracranial large-artery arteriopathy between 1991 and 2005. We assessed clinical features, potential causes, risk factors, extent of infarction and arteriopathy at presentation, long-term angiographic course, and clinical outcome. Of 356 patients with anterior circulation arterial ischemic stroke, 17 (5%) had a documented unilateral intracranial arteriopathy, of whom 14 could be included for follow-up investigations (median age, 34 years; range, 27-49 years). Median duration of follow-up was 8.8 years (range, 1.7-12.8 years). In 11 patients, onset of symptoms was not abrupt. The arteriopathy normalized completely in 5 and improved in 3 patients; in none of the patients did the arteriopathy worsen. Two of 14 patients had recurrent symptoms. Ten patients (71%) had a good outcome (modified Rankin Scale score≤2). In young adults, arterial ischemic stroke is rarely caused by a unilateral intracranial arteriopathy. Similar to children, onset of symptoms in young adults is often not abrupt and the arteriopathy may improve over time. Late recurrences were rare. Possibly, a monophasic inflammatory process, as has been suggested for childhood intracranial focal nonprogressive arteriopathies, also occurs in young adults.

    Full Text Available Pigmented villonodular synovitis (PVNS is a rare, benign, but a locally aggressive tumor. It is characterized by the proliferation of synovial membrane, but it can also be seen in tendon sheaths and bursae. Clinical presentation of solitary lesions include compression and locking of the joint suggesting loose bodies in the joint and a subsequent findings of an effusion, whereas diffuse lesions manifest with pain and chronic swelling. In this article, we presented a curious case of PVNS in a female patient who have been followed up due to an acetabular cystic lesion. She underwent total hip arthroplasty for severe osteoarthritis of the hip joint and associated pain. The diagnosis of PVNS was established intraoperatively.

    Full Text Available Context: Presurgical nasoalveolar moulding (PNAM is a non-surgical method of reshaping the cleft lip, alveolus, palate and the nose to minimize the severity of the cleft deformity, before primary cheiloplastyand palatoplasty. In this context, PNAM proves to be an invaluable asset in the management of unilateral cleft lip and palate. Aims: The study was conducted to evaluate the effi cacy of PNAM in the management of unilateral cleft lip and palate with the following objectives: (1 To assess and compare the degree of reduction in the size of cleft palate and alveolus (pre-PNAM and post-PNAM. (2 To evaluate and compare the improvement in columellar length and correction of columellar deviation (pre-PNAM and post-PNAM. (3 To assess the changes in the position of the alar base and the alar cartilages. Settings and Design: Prospective study. Subjects and Methods: A prospective study consisting of, which included 20 patients with complete unilateral cleft lip and palate was conducted. The age at the start of PNAM treatment of the infants ranged from 2 to 44 days of age reporting to our institute between December 2011 and August 2013. All the patients underwent PNAM therapy before primary cheiloplasty at 6 months of age; clinical parameters were assessed pre- and post-therapy using photographs and dental study models of the maxilla. Statistical Analysis Used: Student's t-test for paired comparisons. Results: Results of the study showed a promising reduction in the cleft size before the surgery, signifi cant improvement in nasal symmetry, including the columellar length on the cleft side. Conclusions: PNAM is a valuable adjunct to our surgical armamentarium in dealing with the challenges of primary closure of unilateral cleft lip and palate thereby enhancing the overall surgical outcome. The advantages of this method include the simplicity of the procedure and improving the quality of surgical repair, particularly in obtaining tension free muscle

    Hallux valgus affects up to 29% of adults and can be bilateral in 84% of cases. Contemporary surgical techniques provide the possibility of simultaneous bilateral correction, but still there is no consensus on whether staged or simultaneous correction should be performed if both feet are involved. The aim of the present study was to report our experience of treatment of patients with hallux valgus and to perform comparative analysis of results obtained from unilateral and simultaneous bilateral surgical correction. Data on 60 feet (40 patients) with hallux valgus that underwent surgery between 2010 and 2013 using scarf osteotomy and lateral soft tissue release were analyzed. Unilateral correction was performed in 30 feet (25 patients) and bilateral correction in 30 feet (15 patients). The patients from both groups were admitted to hospital for 7 days. Functional assessment (American Orthopaedic Foot & Ankle Society [AOFAS] score) and radiographic examination (intermetatarsal and hallux valgus angles) were performed preoperatively and at 6, 12, and 24 months after the procedure. Comparative analysis between groups with bilateral and unilateral correction was carried out. At 24 months after surgery in the bilateral and unilateral groups, the mean AOFAS score was 86 ± 6.2 and 86 ± 6.9 (P > .05), the mean intermetatarsal angle was 8.4 ± 0.5 and 8.8 ± 0.8 degrees (P > .05), and the mean metatarsophalangeal angle was 13.0 ± 1.2 and 13.0 ± 0.9 degrees (P > .05), respectively. According to the data obtained, simultaneous bilateral correction had the same functional and radiographic results as unilateral surgery. Level III, case series. © The Author(s) 2015.

    Objective: It's a study of the collateral circulation secondary to unilateral and bilateral internal carotid artery (ICA) severe stenosis or occlusion using digital subtract angiography (DSA) and magnetic resonance angiography (MRA). Methods: Ninty-five patients with ICA stenosis or occlusion were diagnosed by DSA or MRA. Forty-four patients were assessed by DSA, and fifty-one patients were evaluated by MRA, who were divided into two groups of the unilateral and bilateral involvement. DSA, MRA findings were analyzed, by which the patterns of the collateral circulation were comparatively studied. Results: The presence rate of anterior communicating artery (AcoA) in the unilateral group on DSA and MRA was significantly higher than that in the bilateral group (P 0.05). On DSA, the presence rate of ophthalmic artery (OphA) in the unilateral and bilateral groups had no significant difference between the two groups. The augmentation rate of the OphA in the bilateral group was significantly higher than that in the unilateral group (P<0.05). The presence rate of leptomeningeal anastomosis in the bilateral group was significantly higher than that in the unilateral group on DSA and MRA (P<0.01). Conclusion: In patients with the unilateral and bilateral ICA stenosis or occlusion, the collateral circulation formats in different patterns. The major collateral pathways secondary to the unilateral ICA stenosis or occlusion are AcoA and ispilateral PCoA, while to the bilateral ICA stenosis or' occlusion are PCoA, OPhA, and leptomeningeal anastomosis.

    Corneal collagen crosslinking (CXL) with ultraviolet-A energy plus riboflavin has become a ubiquitous treatment in early keratoconus, although its long-term safety is unknown. We describe severe sequelae in a CXL-treated patient after he underwent a standard deep anterior lamellar keratoplasty procedure. In April 2009, a healthy 49-year-old male patient (R.H.) underwent bilateral CXL according to the Dresden protocol for progressive keratoconus stage 3. The best-corrected visual acuity did not improve over 20/100 within a postoperative period of 2 years, and contact lenses were not tolerated. Consequently, a unilateral deep anterior lamellar keratoplasty was performed, to transplant an 8-mm fully epithelialized button onto an 8-mm bed with a bared Descemet membrane (surgeon: J.H.K.). The postoperative healing course was unusually disturbed. Sutures pulled through the recipient tissue, which required suture replacement. Portions of the epithelium sloughed off repeatedly, and bulky regrowth displayed no attachment to the Bowman membrane. Within the first weeks, the transplant became cloudy. Two biopsies were removed from the limbus area and submitted to independent histopathological laboratories, both of which diagnosed the condition as epithelial neoplasia. Pathology tests indicated conjunctival intraepithelial neoplasia, the preliminary stage of invasive squamous cell carcinoma, in the keratocyte-voided bed of the recipient. This case suggests that CXL might hamper the ocular healing process and, combined with subsequent corneal surgery, could potentially initiate neoplasia. Further investigation is warranted to determine the safety of the combination of ultraviolet-A/riboflavin treatment and subsequent corneal tissue transplantation.

    To investigate the upper-extremity abduction, and lifting limitations and associated factors after anterior cervical decompression and fusion. A total of 117 patients who underwent anterior cervical decompression and fusion for cervical spondylosis were assessed retrospectively. Their upper-extremity abduction and lifting capacity after operation and manual muscle test grade for deltoid muscle strength and its sensory status were recorded. In addition, spinal cord function (Japanese Orthopaedic Association and Neck Disability Index scores) and C4-5 intervertebral height (radiographs) were assessed. Finally, high signal and ossification of posterior longitudinal ligament were observed by T2 magnetic resonance imaging and computed tomography, respectively. Seven individuals had a decrease in muscle strength, with 2 patients also exhibiting sensory defect. Six individuals had bilateral weakness of deltoid and biceps brachii and 1 of unilateral. After 8-16 months of follow-up, the abduction function and lift capacity were restored. The manual muscle test grade recovered to 5 and 4 degrees, respectively, in 6 and 1 patients. Two patients remained with sensory defect. The mean recovery time 19.7 days on average, and Japanese Orthopaedic Association scores significantly improved. Among the 117 patients, less than 2-level decompression showed upper-extremity function limitations in 1 of 67 (1.5%), whereas more than a 3-level decompression resulted in greater rate in 6 of 50 (12%), a significant difference (P magnetic resonance imaging. The rate of upper-extremity abduction and lifting limitation after anterior cervical decompression and fusion is low, indicating a good prognosis after active treatment.

    A new method of early neonatal cheiloplasty has recently been employed on patients having complete unilateral cleft lip and palate (cUCLP). We aimed to investigate (1) their detailed palatal morphology before surgery and growth during the 10 months after neonatal cheiloplasty, (2) the growth of eight dimensions of the maxilla in these patients, (3) the development of these dimensions compared with published data on noncleft controls and on cUCLP patients operated using later operation protocol (LOP; 6 months of age). Sixty-six virtual dental models of 33 longitudinally evaluated cUCLP patients were analysed using metric analysis, a dense correspondence model, and multivariate statistics. We compared the palatal surfaces before neonatal cheiloplasty (mean age, 4 days) and before palatoplasty (mean age, 10 months). The palatal form variability of 10-month-old children was considerably reduced during the observed period thanks to their undisturbed growth, that is, the palate underwent the same growth changes following neonatal cheiloplasty. A detailed colour-coded map identified the most marked growth at the anterior and posterior ends of both segments. The maxilla of cUCLP patients after neonatal cheiloplasty had a growth tendency similar to noncleft controls (unlike LOP). Both methodological approaches showed that early neonatal cheiloplasty in cUCLP patients did not prevent forward growth of the upper jaw segments and did not reduce either the length or width of the maxilla during the first 10 months of life.

    Currently, the optimal surgical approach for bilateral aneurysms remains controversial. Alternative interventional methods, such as unilateral or bilateral approaches, have been used during a single session or 2 different sessions. The unilateral approach can be used successfully to treat contralateral aneurysms that develop in a paramedian location. However, such an approach is more difficult for treating contralateral aneurysms in more distant locations. The unilateral approach can decrease complication rates, operation time, and length of hospital stay. In this study, we aimed to identify when the unilateral approach should be chosen in patients with bilateral middle cerebral artery (MCA) aneurysms and to compare the effect of each approach on the operation time and duration of hospital stay. Between March 2003 and May 2016, 17 bilateral MCA aneurysms were diagnosed in patients who presented to our clinic with complaints of headache and a diagnosis of subarachnoid hemorrhage. The extent of the cerebral edema, A1 + M1 distance on the opposite site, and configuration of the contralateral aneurysm were determined by preoperative radiologic studies. Based on these findings, 7 patients underwent unilateral surgery, and 10 patients received the bilateral approach. The 2 groups had a very similar postoperative course. Nonetheless, the operation time and hospital stay were significantly longer for patients who underwent bilateral surgery than those treated with the unilateral approach. In selected patients with bilateral MCA aneurysms, the unilateral approach is a favorable alternative that is less invasive, decreases the operation time and hospital stay, and leads to fewer complications.

    Full Text Available Most unilateral pedicle stress fractures occur on the contralateral side of patients with unilateral spondylolysis. However, there are few reports of unilateral pedicle stress fractures in patients with bilateral spondylolysis and spondylolisthesis. We report a unique case of unilateral pedicle stress fracture in a long-term hemodialysis patient with isthmic spondylolisthesis. A 65-year-old man who had undergone hemodialysis presented with lower back pain that had persisted for several years. The patient experienced severe right lower extremity pain with no history of trauma. Computed tomography revealed unilateral pedicle fracture with bilateral L5 spondylolysis and spondylolisthesis with progression of scoliosis. The patient underwent Gill laminectomy of L5 with pedicle screw fixation at L4-S1 and interbody fusion at L5-S1. The patient’s leg pain ceased immediately, and he began walking without leg pain. In our present patient, development of scoliosis caused by destructive spondyloarthropathy may have contributed to a unilateral pedicle fracture.

    Five reports have examined unilateral submandibular gland aplasia. The purposes of this report are to demonstrate submandibular gland aplasia leading to contralateral gland hypertrophy in the setting of oral cavity cancer and to discuss the corresponding diagnostic and management challenges. This study is a case report of a 60-year-old male who presented with pain on the right side of the mobile tongue. This report uses literature review. A 60-year-old male presented with pain on the right side of the mobile tongue. Subsequent results of punch biopsy revealed squamous cell carcinoma in situ with foci of microinvasion of the tongue. Head and neck examination revealed no abnormalities. The patient underwent a wide-local excision of the tongue lesion. Postoperative computed tomographic (CT) scan showed an asymmetric mass on the ipsilateral side of the cancer in the region of the submandibular gland. The gland was noted to be abnormally large. A diagnosis of contralateral submandibular gland aplasia was made. The patient is cancer-free at 2 years postlocal excision. Salivary gland aplasia is an extremely rare disorder and is often associated with various congenital syndromes. Unilateral submandibular gland aplasia is even rarer with ours representing the sixth reported case. Aplasia is believed to stem from a regional disturbance in early fetal development. Common symptoms can include dysphagia, dry mouth, decreased taste, and tooth decay. In the presence of a history of oral cavity cancer, unilateral submandibular gland aplasia poses a challenge during postoperative cancer follow-up. Unilateral submandibular gland aplasia in the setting of oral cavity cancer poses a unique challenge for cancer follow-up. Hypertrophy of the submandibular gland on the other side can masquerade as nodal metastasis. Head and neck examination as well as CT scan can be inconclusive. Regular confirmatory tests such as fine needle aspiration biopsy and positron emission tomography/CT for

    Case studies of patients with cervical spondylosis with unilateral upper extremity amyotrophy. To clarify the surgical outcome of posterior decompression for this amyotrophy. Cervical spondylosis sometimes causes a characteristic severe muscular atrophy without sensory disturbance or lower-extremity dysfunction, which is the so-called "cervical spondylotic amyotrophy." However, response to treatment, especially to posterior decompression, has not been well understood. This study included 32 patients. All underwent posterior cervical laminoplasty, and 22 patients had an additional foraminotomy. Preoperative and postoperative muscle power and results of imaging and electrophysiologic studies were evaluated. The follow-up period averaged 78 months. Whether impingement was against the ventral nerve root (VNR) or anterior horn (AH) in the spinal cord was assessed according to these findings. These cases were divided into proximal type and distal type according to the most severely atrophic muscle and compared statistically. Severe preoperative muscle atrophy was observed in the deltoid and biceps muscles of 24 patients (proximal type) and in the forearm and hand muscles of 8 patients (distal type). Impingements against the VNR and AH were observed in 21 and 28 cases, respectively, and 17 cases had impingement of both the VNR and AH. Improvements in muscle atrophy after surgery were observed in 25 cases. In proximal-type patients, muscle power improved in 92% of cases but was improved in only 38% of the distal-type cases. Laminoplasty and foraminotomy were effective in the treatment of most patients with this syndrome, although the outcome in the distal type was inferior to that in the proximal type.

    Measurement of anterior chamber volume is discussed and attention drawn to a new, convenient slit-image method, which was used to study anterior chamber depth and volume before and after prophylactic peripheral iridectomy in the fellow eyes of patients presenting with unilateral acute angle-closure glaucoma. There was no significant change in depth after iridectomy but the mean anterior chamber volume increased significantly (P less than 0.01), by nearly 3 per cent. This increase was due to elimination of peripheral iris bombé which was not present in two control groups of normal eyes, one matched for anterior chamber depth and the other for age and refraction. Peripheral iris bombé may be a quantifiable factor predisposing to the development of acute angle-closure glaucoma.

    This clinical focus article provides preliminary findings from a multicenter longitudinal study investigating auditory and communication development in children with mild bilateral or unilateral hearing loss of any degree. A total of 100 children (55 with mild bilateral or unilateral hearing loss and 45 with normal hearing) underwent 1 or more assessments from a battery of auditory and language measures. Children up to age 4 years demonstrated auditory and language skills similar to those of children with normal hearing. Factors that affect outcomes in communication development will be explored as additional data are collected in this ongoing study.

    2017-06-01

    A retrospective cohort study was conducted to analyze the relapse rate of anterior open bite (AOB) correction comparing Le Fort I osteotomy with and without anterior segmentation. The risk factors that might contribute to relapse were also assessed. Lateral cephalograms obtained at six different times were analyzed. A total of 81 patients with AOB were recruited. Thirty-five patients underwent Le Fort I osteotomy without anterior segmentation and 46 patients underwent anterior segmentation. Le Fort I osteotomy with anterior segmentation resulted in significantly more AOB relapse when compared to that without anterior segmentation at 7 weeks postoperative (15.2% vs. 0%, P=0.016). During the early postoperative period, factors that contributed to AOB relapse in Le Fort I osteotomy with anterior segmentation were AOB closure ≥4mm and inferior positioning of the anterior segment >2mm. Over the long term, AOB closure ≥4mm and intraoral vertical ramus osteotomy as the only mandibular procedure were factors identified as causing more AOB relapse in those treated by Le Fort I osteotomy with anterior segmentation. In conclusion, Le Fort I osteotomy without anterior segmentation was found to be more stable in the surgical correction of AOB in the early and late postoperative periods.

    The purpose of this study was to evaluate the prevalence of anterior knee pain in anatomic double-bundle anterior cruciate ligament (ACL) reconstruction and to identify critical factors affecting postoperative anterior knee pain development. Subjects comprised 171 patients (171 knees) who underwent anatomic double-bundle ACL reconstruction with a follow-up period of ≥2 years. The procedure used bone-patellar tendon-bone plus gracilis tendon (BTB-G) in 56 knees, semitendinosus tendon (ST) in 71 knees, and ST-G in 44 knees. Clinical results and prevalence and severity of anterior knee pain were assessed at 3 months and 2 years postoperatively. Clinical variables influencing anterior knee pain development at each postoperative period were subjected to univariate analysis, followed by logistic regression analysis to identify risk factors for anterior knee pain. Overall prevalences of anterior knee pain at 3 months and 2 years postoperatively were 42.0 and 11.1%, respectively. Use of BTB-G graft represented the highest prevalence of anterior knee pain between the 3 different grafts (P = 0.001); however, this statistical significance disappeared at 2 years postoperatively. Prevalence of postoperative extension deficit was significantly higher in anterior knee pain-positive cohort than in anterior knee pain-negative cohort at 3 months postoperatively. Level of quadriceps strength was significantly lower, and Lysholm score was significantly worse in anterior knee pain-positive cohort than in anterior knee pain-negative cohort at 2 years postoperatively. According to logistic regression analysis, knee extension deficit was a predisposing factor for the development of anterior knee pain at 3 months postoperatively (odds ratio, 2.76; P = 0.004); however, there was no significant predisposing factor for anterior knee pain at 2 years postoperatively. Knee extension deficit was an important predisposing factor for postoperative anterior knee pain in the early

    CT images of 6 patients with malignant lymphomas, that were revealed as the anterior mediastinal masses on the conventional chest radiographs, were studied. Plain CTs showed diffuse involvements of the anterior mediastinums in 4 patients and large unilateral enlargements of thymus lobes in the remaining 2 patients. The tumors showed relatively homogeneous densities, but on close observation, several slightly low density patchy areas within them were revealed. The inhomogeneity of the tumors was characteristically accentuated on the contrast enhancement CTs. The fatty plane between the mass and the mediastinal structures was indistinct. No tumor calcification was shown. (author)

    Full Text Available In the course of investigations at Romuliana nine antler three-partite combs with a single row of teeth were found in the Late Roman horizons dating from the late 4th - mid 5th century. They were found in Tower 19, in the Palace II sector and in the Thermae sector. The combs can be classified as two types: three-partite unilateral combs with semicircular handle (Petković comb type VII and three-partite unilateral combs with triangular handle decorated with horse protomes (Petković comb type VI. Two groups of these finds were distinguished after more detailed analysis; the earlier one including specimens originating from the Chernyahov-Sîntana de Mureº culture and later one including specimens made under "barbarian"influence and produced in Romuliana. These finds confirm the continuity of settlement at Romuliana in the Late Roman period, from the final quarter of the 4th until the end of the 5th century and open up the question of the character of the settlement.

    To evaluate the functional results obtained after voice therapy in patients with unilateral vocal fold paralysis caused by different aetiologies. Prospective analysis of the outcome of unilateral vocal fold paralysis cases treated at our speech and language rehabilitation service from November 2003 to January 2006. Thirty cases underwent behavioural treatment, between two and six weeks after unilateral vocal fold paralysis onset. A multi-dimensional assessment was carried out before, immediately after and six months after treatment. After behavioural therapy, the prevalence of complete glottal closure increased significantly (p voice range profile analysis showed a significant decrease of lowest voice frequency and a significant increase of the number of semitones (p < 0.05). Mean values for grade, instability, breathiness, asthenia and voice handicap index scores were significantly decreased both immediately and six months after treatment, compared with pre-treatment values (p < 0.05). Early voice therapy may enable significant improvement in vocal function, allowing the patient to avoid surgery.

    Unilateral spondylolysis and midline defects in the posterior spinal elements attributable to spina bifida occulta (SBO) result in the unilateral floating of the vertebral arch. We report a patient with unilateral spondylolysis associated with SBO in the lumbar spine and review the literature. This 71-year-old male experienced severe left leg pain and lumbago that worsened upon walking. Radiographic studies revealed SBO and unilateral spondylolysis of L5. The dural sac and left L5 nerve root were compressed by the organization of tissues around the spondylolysis. As his symptoms failed to respond to conservative treatment, he underwent unilateral laminectomy without fusion. At operation, the left lamina of L5 was floating and unstable; the right lamina was stable. Medial facetectomy at L4/5 and excision of the left floating lamina of L5 were performed. For satisfactory decompression of the dural sac and left L5 nerve root, the cartilaginous fibrous tissue around the lysis was removed. His symptoms disappeared immediately after surgery. Although long-term follow-up is necessary, we suggest that unilateral microdecompression without fusion is a useful method to treat patients with unilateral spondylolysis with SBO.

    Full Text Available Congenital anterior tibiofemoral subluxation is an extremely rare disorder. All reported cases accompanied by other abnormalities and syndromes. A 16-year-old high school girl referred to us with bilateral anterior tibiofemoral subluxation as the knees were extended and reduced at more than 30 degrees flexion. Deformities were due to tightness of the iliotibial band and biceps femuris muscles and corrected by surgical release. Associated disorders included bilateral anterior shoulders dislocation, short metacarpals and metatarsals, and right calcaneuvalgus deformity.

  6. Mechanism of Activating the Proprioceptive NT-3/TrkC Signalling Pathway by Reverse Intervention for the Anterior Cruciate Ligament–Hamstring Reflex Arc with Electroacupuncture

    Full Text Available The anterior cruciate ligament (ACL is an important structure maintaining stability of the knee joints. Deficits in physical stability and the proprioceptive capabilities of the knee joints are observed, when the ACL is damaged. Additionally, a unilateral ACL injury can affect bilateral knee proprioception; therefore, proprioception of the ACL may play a key role in stability. Electroacupuncture therapy has a definite effect nerve regeneration. In this study, cynomolgus monkeys were randomly divided into 4 groups: the model control group, intervention of the injured knee with electroacupuncture (IIKE group, intervention of the bilateral knees with electroacupuncture (IBKE group, and the blank control group. The unilateral ACL injury model was developed in IIKE and IBKE groups; acupuncture points around the knees underwent intervention similarly in the IIKE and IBKE groups. Then, mRNA and protein expressions of NT-3 and TrkC in the dorsal root ganglion and of growth-associated protein-43 in the ACL increased according to reverse-transcription quantitative polymerase chain reaction and Western blotting results. Decreased incubations and increased amplitudes were found for somatosensory-evoked potentials and motor nerve conduction velocity. The finding indicates that electroacupuncture may play an important role in the recovery of proprioception in the ACL by activating the NT-3/TrkC signalling pathway.

    Prepubertal unilateral gynecomastia is an extremely rare condition. At present, its etiology and management strategy are not well known. 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. PMID:25541897

    Post traumatic anterior abdominal wall hernia can be ignored in emergency settings. We here report the case of a 32-year-old patient with a BMI of 30 kg/m 2 , suffering from anterior abdominal wall hernia as a result of a road accident. This lesion wasn't detected during clinical examination. Abdominal tomodensitometry showed a defect of 8 cm in the anterior abdominal wall. The patient underwent surgery during which a musculoaponeurotic defect of 12 cm was detected. The repair was carried out using interrupted suture. The postoperative course was marked by a secondarily infected skin necrosis. The evolution was satisfactory after directed cicatrization. At 3 months postoperatively the patient was doing well with a healed wound and a strong abdominal wall.

Case series with chart review of patients presenting positional vertigo and positional downbeating nystagmus during a 2-year period. Outpatients' tertiary referral center for balance disorders. Eighteen patients suffering from positional vertigo and presenting positional downbeating nystagmus were treated with a maneuver based on a modification of the procedure proposed by Crevits. disappearance of positional downbeating nystagmus. Positional downbeating nystagmus was elicited unilaterally with the Dix-Hallpike maneuver in 6 cases. In 4 patients, it was triggered by both left and right Dix-Hallpike tests. In 8 patients, the positional nystagmus was elicited by a straight head-hanging maneuver. The positional nystagmus was purely downbeating in 12 patients. In the remaining, a torsional component was detected. After the treatment, only 1 patient showed positional nystagmus at 30 days. In anterior canal benign paroxysmal positional vertigo, the presence of a positional downbeating nystagmus in response to positional tests is key for diagnosis. In a significant number of patients, the affected side may not be detected because of the inconstant presence of a torsional component. Treatment with a simplified maneuver based on Crevits's technique can be considered an effective method for the treatment of anterior canal lithiasis, especially when the affected side cannot be detected clearly.

    The aim of our study was to evaluate the effects of gender on recovery of knee joint biomechanics over the stance phase of gait after reconstruction of the anterior cruciate ligament (ACL). Gait parameters and knee joint kinematics and kinetics were compared in 32 patients (16 male and 16 female) who underwent ACL reconstruction for a unilateral ACL deficiency, with comparison to an age-, height-, and weight-matched Control group. Knee flexion, adduction and tibial rotation angles were measured and knee extension and abduction moment was calculated by inverse dynamics methods. Females exhibited more tibial external rotation, in both the Control and ACL groups (P<0.05), which was not changed after ACL reconstruction. Prior to reconstruction, sagittal plane biomechanics were changed, in both males and females, compared to the Control groups (P<0.05). These abnormal sagittal plane mechanics were recovered at 12months, but not six months post-reconstruction. We identified gender-based differences in tibial rotation that influenced the kinematics and kinetics of the knee over the stance phase of gait, both pre-operatively and post-ACL reconstruction. Evaluation of biomechanical effects of ACL injury, before and after reconstruction, should be separately evaluated for females and males. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available OBJECTIVE: To ascertain the coronal angles for the femoral and tibial tunnels that provide the best postoperative result from anterior cruciate ligament (ACL reconstruction surgery, through assessing the variables of the IKDC and Lysholm-Tegner questionnaires and the hop test.METHODS: Sixteen patients with a single unilateral ACL injury who underwent this surgery between 24 and 36 months earlier were evaluated. They were divided into four groups in which the tibial and femoral tunnel angles were greater than or less than 65° in the coronal plane.RESULTS: The results demonstrated that a more vertical angle for the tibial tunnel (72° and a more horizontal angle for the femoral tunnel (60°, with valgus alignment of 12° correlated with the best values for the variables studied. This may indicate that the long-term results from this surgery are excellent.CONCLUSION: A more horizontal femoral angle and a more vertical tibial angle produced better assessments in the tests that were applied and in the functional results evaluated.

    The present authors report a case of unilateral traumatic oculomotor nerve paralysis which shows interesting CT findings which suggest its mechanism. A 60-year-old woman was admitted to our hospital with a cerebral concussion soon after a traffic accident. A CT scan was performed soon after admission. A high-density spot was noted at the medial aspect of the left cerebral peduncle, where the oculomotor nerve emerged from the midbrain, and an irregular, slender, high-density area was delineated in the right dorsolateral surface of the midbrain. Although the right hemiparesis had already improved by the next morning, the function of the left oculomotor nerve has been completely disturbed for the three months since the injury. In our case, it is speculated that an avulsion of the left oculomotor nerve rootlet occurred at the time of impact as the mechanism of the oculomotor nerve paralysis. A CT taken soon after the head injury showed a high-density spot; this was considered to be a hemorrhage occurring because of the avulsion of the nerve rootlet at the medial surface of the cerebral peduncle.

    Antebrachial agenesis is a congenital deformity which is not invalidating for the children who have a level of independence comparable to that of other children of the same age. Although the appropriateness of a prosthesis is rarely questioned by healthcarers, it is clear that it is the healthcarers' own representation of this condition (their knowledge of the deformity and of the prosthesis proposed) that leads to the indication. The purpose of this study was to better understand the respective representations of unilateral antebrachial agenesis to help determine appropriate health care proposals. An intensive survey using semi-directive interviews was conducted in 16 families. Group interviews with three healthcare teams were then conducted. Three leading topics appeared: worry about the social integration of the child, a paradoxical representation of the child perceived as independent but handicapped, and a largely negative image of the prosthesis. There was a rather important difference in the representations formulated by the parents and by the healthcarers. The discussion focused on awareness of the narcissistic content of the expectations and the plastic and functional implications of prosthesis fitting, perceived differently by parents and healthcarers. The nature of the expected result involves a change in the representation of the child more than a change in the child's body, a concept which in itself is not a true objective of healthcare. Taken the understandably difficult position of healthcarers, it might be useful to propose a different scheme for the first consultation.

    Document the use of transcanal labyrinthectomy to treat disabling attacks of vertigo after unilateral cochlear implantation. A 46-year-old woman with severe-profound bilateral sensorineural hearing loss secondary to enlarged vestibular aqueducts underwent cochlear implantation for her right ear with a Nucleus Freedom device. The surgery was uneventful, and postoperative imaging confirmed that the electrode was positioned properly. She developed episodic vertigo 10 to 14 days after the implant surgery, which failed to improve with aggressive vestibular rehabilitation therapy. Plugging of the round window for possible perilymphatic fistula did not relieve her symptoms. Right transcanal labyrinthectomy supplemented by filling the vestibule with gentamicin-soaked Gelfoam and then a customized vestibular rehabilitation program. Comparison of vestibular symptoms and cochlear implant performance before and after transcanal labyrinthectomy. The patient had immediate relief of symptoms, and the function of the cochlear implant was not adversely affected. Transcanal labyrinthectomy may be an effective method to ablate the vestibular end organ after unilateral cochlear implantation. It can offer relief of disabling vertigo without adversely affecting the performance of the implant.

    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.

    The aim of this study was to investigate whether bilateral widespread pressure hypersensitivity exists in patients with unilateral carpal tunnel syndrome. A total of 20 females with carpal tunnel syndrome (aged 22-60 years), and 20 healthy matched females (aged 21-60 years old) were recruited. Pressure pain thresholds were assessed bilaterally over median, ulnar, and radial nerve trunks, the C5-C6 zygapophyseal joint, the carpal tunnel and the tibialis anterior muscle in a blinded design. The results showed that pressure pain threshold levels were significantly decreased bilaterally over the median, ulnar, and radial nerve trunks, the carpal tunnel, the C5-C6 zygapophyseal joint, and the tibialis anterior muscle in patients with unilateral carpal tunnel syndrome as compared to healthy controls (all, P < 0.001). Pressure pain threshold was negatively correlated to both hand pain intensity and duration of symptoms (all, P < 0.001). Our findings revealed bilateral widespread pressure hypersensitivity in subjects with carpal tunnel syndrome, which suggest that widespread central sensitization is involved in patients with unilateral carpal tunnel syndrome. The generalized decrease in pressure pain thresholds associated with pain intensity and duration of symptoms supports a role of the peripheral drive to initiate and maintain central sensitization. Nevertheless, both central and peripheral sensitization mechanisms are probably involved at the same time in carpal tunnel syndrome.

    The premature fusion of unilateral coronal suture can cause a significant asymmetry of the craniofacial skeleton, with an oblique deviation of the cranial base that negatively impacts soft tissue facial symmetry. The purpose of this study was to assess facial symmetry obtained in patients with unilateral coronal synostosis (UCS) surgically treated by 2 different techniques. We hypothesized that nasal deviation should not be addressed in a primary surgical correction of UCS. Consecutive UCS patients were enrolled in a prospective study and randomly divided into 2 groups. In group 1, the patients underwent total frontal reconstruction and transferring of onlay bone grafts to the recessive superior orbital rim (n = 7), and in group 2, the patients underwent total frontal reconstruction and unilateral fronto-orbital advancement (n = 5). Computerized photogrammetric analysis measured vertical and horizontal axis of the nose and the orbital globe in the preoperative and postoperative periods. Intragroup and intergroup comparisons were performed. Intragroup preoperative and postoperative comparisons showed a significant (all P 0.05). Facial symmetry was achieved in the patients with UCS who underwent surgery regardless of surgical approach evaluated here. Our data showed a significant improvement in nasal and orbital-globe deviation, leading us to question the necessity of primary nasal correction in these patients.

    The aim of this study was to identify the risk factors for anterior knee pain in patients with cerebral palsy. This prospective study investigated the risk factors for anterior knee pain in 127 ambulatory patients with spastic cerebral palsy in terms of walking pain, resting pain, and provocative pain. Demographic data analysis and physical examination for measuring the knee flexion contracture and unilateral and bilateral popliteal angles were performed. Patellar height was measured on radiographs, and patella alta was identified. The risk factors for anterior knee pain were analyzed using multivariate analysis with a generalized estimating equation. Seventy-seven patients were found to have patella alta based on the radiographic measurements (60.6%). Overall, sixteen patients (12.6%) had either unilateral or bilateral anterior knee pain. Of these, 6 patients showed a visual analogue scale (VAS) ≤ 3, 9 patients showed 3 7. Age was found to be a significant risk factor for walking pain and resting pain with odds ratios (ORs) of 1.08 (95% confidence interval [CI], 1.02 to 1.14) and 1.09 (95% CI, 1.03 to 1.15), respectively. In the multivariate analysis, knee flexion contracture was a significant protective factor with an OR of 0.92 (95% CI, 0.85 to 0.98). Approximately 12.6% of ambulatory patients with spastic cerebral palsy were found to have anterior knee pain in our hospital-based cohort study. Age was found to be a significant risk factor for anterior knee pain while walking and resting.

  4. BILATERAL ANTERIOR DISLOCATION OF SHOULDER WITH GREATER TUBEROSITY FRACTURE DUE TO HYPONATREMIA : A RARE PRESENTATION

    Full Text Available We here report a rare presentation of bilateral anterior dislocation of shoulder with associated fracture of greater tuberosity in a 38 year old male due to minor trauma which he sustained secondary to hyponatremia induced irritability. There was no associ ated rotator cuff tear which is often associated with BADS which makes this presentation unique. Unilateral dislocation of shoulder is a common condition which is frequently encountered in emergency trauma department. Anterior dislocation is more common th an posterior dislocation. However, simultaneous bilateral shoulder dislocations are usually posterior. Bilateral anterior dislocations with fractures of the greater tuberosity are even rarer and are usually associated with trauma or seizures

    Tearing of the anterior capsule of the shoulder is a rare but debilitating injury for throwing athletes. However, there is very little in the literature to guide its diagnosis and treatment. In this case series, we outline our experience with anterior capsular tears of the shoulder in professional baseball players. Five professional baseball players were diagnosed with midsubstance tears of their anterior capsule. A trial of rest and rehabilitation failed in all patients, and they eventually underwent surgery. These patients were retrospectively reviewed. The presenting symptoms and findings were documented, and outcomes were assessed by the player's ability to return to play. The mean age was 33.5 years (range, 31-37 years), and all patients presented with anterior shoulder pain and the inability to throw. No patient had an acute traumatic injury. Magnetic resonance imaging provided the correct diagnosis in 4 patients, and the diagnosis was made with diagnostic arthroscopy in the fifth. Three underwent arthroscopic repair, and 2 underwent open repair of the anterior capsule. Of the 5 players, 4 (80%) returned to their preinjury level by a mean of 13.3 months (range, 8-18 months). Anterior capsular tears can occur in older throwing athletes. Surgical repair, whether arthroscopic or open, can yield good results in most patients.

    This study aimed to compare the memory outcome following left anterior temporal lobectomy (ATL) between patients with a failed Wada test and patients who passed the Wada test. From 1996 to 2002, we performed the Wada test on all patients with unilateral left mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) and concordant electroclinical data before ATL. We used a 12-item recognition paradigm for memory testing and awarded a score of +1 for each correct response and -0.5 for each incorrect response. No patient was denied surgery on the basis of Wada scores. We assessed cognitive and memory functions using the Wechsler Adult Intelligence Scale and the Wechsler Memory Scale preoperatively and at one year after ATL. We compared the number of patients who showed decline in memory scores, as per the published reliable change indices, between the patients with a failed Wada test and the patients who passed the Wada test. Out of the 116 eligible patients with left MTLE-HS, 88 underwent bilateral Wada test, while 28 underwent ipsilateral Wada test. None of them developed postoperative amnesia. Approximately, one-third of patients with a failed Wada memory test when the failure was defined as a contralateral score of 8, and as an asymmetry score of failed Wada memory test and the group who passed the Wada memory test. The results remained the same when analyses were repeated at various other cutoff points. The patients with left MTLE-HS with concordant electroclinical, MRI, and neuropsychological data should not be denied ATL solely on the basis of Wada memory test results.

    Lower extremity spasticity is a common sequela among patients with acquired brain injury. The optimum treatment remains controversial. The aim of our study was to test the feasibility and effectiveness of contralateral nerve root transfer in reducing post stroke spasticity of the affected hindlimb muscles in rats. In our study, we for the first time created a novel animal hindlimb spastic hemiplegia model in rats with photothrombotic lesion of unilateral motor cortex and we established a novel surgical procedure in reducing motor cortex lesion-induced hindlimb spastic hemiplegia in rats. Thirty six rats were randomized into three groups. In group A, rats received sham operation. In group B, rats underwent unilateral hindlimb motor cortex lesion. In group C, rats underwent unilateral hindlimb cortex lesion followed by contralateral L4 ventral root transfer to L5 ventral root of the affected side. Footprint analysis, Hoffmann reflex (H-reflex), cholera toxin subunit B (CTB) retrograde tracing of gastrocnemius muscle (GM) motoneurons and immunofluorescent staining of vesicle glutamate transporter 1 (VGLUT1) on CTB-labelled motoneurons were used to assess spasticity of the affected hindlimb. Sixteen weeks postoperatively, toe spread and stride length recovered significantly in group C compared with group B (P<0.001). Hmax (H-wave maximum amplitude)/Mmax (M-wave maximum amplitude) ratio of gastrocnemius and plantaris muscles (PMs) significantly reduced in group C (P<0.01). Average VGLUT1 positive boutons per CTB-labelled motoneurons significantly reduced in group C (P<0.001). We demonstrated for the first time that contralateral L4 ventral root transfer to L5 ventral root of the affected side was effective in relieving unilateral motor cortex lesion-induced hindlimb spasticity in rats. Our data indicated that this could be an alternative treatment for unilateral lower extremity spasticity after brain injury. Therefore, contralateral neurotization may exert a potential

    This study was designed to compare baseline data and clinical outcome between patients with prostate enlargement/benign prostatic hyperplasia (PE/BPH) who underwent unilateral and bilateral prostatic arterial embolization (PAE) for the relief of lower urinary tract symptoms (LUTS). This single-center, ambispective cohort study compared 122 consecutive patients (mean age 66.7 years) with unilateral versus bilateral PAE from March 2009 to December 2011. Selective PAE was performed with 100- and 200-{mu}m nonspherical polyvinyl alcohol (PVA) particles by a unilateral femoral approach. Bilateral PAE was performed in 103 (84.4 %) patients (group A). The remaining 19 (15.6 %) patients underwent unilateral PAE (group B). Mean follow-up time was 6.7 months in group A and 7.3 months in group B. Mean prostate volume, PSA, International prostate symptom score/quality of life (IPSS/QoL) and post-void residual volume (PVR) reduction, and peak flow rate (Qmax) improvement were 19.4 mL, 1.68 ng/mL, 11.8/2.0 points, 32.9 mL, and 3.9 mL/s in group A and 11.5 mL, 1.98 ng/mL, 8.9/1.4 points, 53.8 mL, and 4.58 mL/s in group B. Poor clinical outcome was observed in 24.3 % of patients from group A and 47.4 % from group B (p = 0.04). PAE is a safe and effective technique that can induce 48 % improvement in the IPSS score and a prostate volume reduction of 19 %, with good clinical outcome in up to 75 % of treated patients. Bilateral PAE seems to lead to better clinical results; however, up to 50 % of patients after unilateral PAE may have a good clinical outcome.

    Laparoscopic ovarian drilling (LOD) has been put forward as the treatment of choice in women with clomiphene citrate (CC)-resistant polycystic ovary syndrome (PCOS), with tubo-ovarian adhesion formation as the major disadvantage. Our study proposed to compare the efficacy of laparoscopic unilateral ovarian drilling with bilateral ovarian drilling in terms of ovulation and pregnancy rate with the expected advantage of decreasing postoperative adhesion rate and change in fimbiro ovarian relationship with unilateral drilling. This prospective randomized study included 44 patients with anovulatory infertility due to PCOS. Twenty-two patients underwent unilateral ovarian drilling in group-I and 22 patients underwent bilateral ovarian drilling in group-II between June 2005 and June 2007. The number of drilling site in each ovary was limited to five. The clinical and biochemical response, ovulation and pregnancy rates over a follow-up period of 1 year were compared. Tubo-ovarian adhesion rate was compared during cesarean section or during repeat laparoscopy. There was no statistical difference between the two groups in terms of clinical and biochemical response, ovulation rate and pregnancy rate. Postoperatively, tubo-ovarian adhesions could be assessed in 36.3% of the patients and no adhesions were found in a single case in either group. Unilateral drilling cauterization of ovary is equally efficacious as bilateral drilling in inducing ovulation and achieving pregnancy. Unilateral ovarian drilling may be a suitable option in clomiphene citrate resistant infertility patient of PCOS which can replace bilateral ovarian drilling with the potential advantage of decreasing the chances of adhesion formation.

    To describe the imaging findings in eight cases of unilateral tensor fascia lata (TFL) hypertrophy presenting as soft tissue masses. Imaging studies and medical charts of eight patients were reviewed retrospectively. The imaging studies included five radiographs, five computed tomography (CT) and six magnetic resonance imaging (MRI) examinations. The majority of patients (seven of eight) presented with a palpable proximal anterior thigh mass. One patient was asymptomatic and incidentally diagnosed. There were six females and two males. Ages ranged from 27 to 86 years old (mean 61). MRI and CT showed unilateral enlargement of the TFL muscle in all cases. TFL muscle hypertrophy is an uncommon clinical entity, which can simulate a soft tissue tumor. The characteristic appearance on CT or MRI allows a confident diagnosis of muscle hypertrophy to be made, avoiding unnecessary biopsy or surgical intervention. (orig.)

  11. Unilateral renal cell carcinoma with coexistent renal disease: a rare cause of end-stage renal disease.

    Peces, R; Alvarez-Navascués, R

    2001-02-01

    Renal cell carcinoma (RCC) is a disorder encompassing a wide spectrum of pathological renal lesions. Coexistence of unilateral RCC and associated pathology in the contralateral kidney is an unusual and challenging therapeutic dilemma that can result in renal failure. So far, data on unilateral RCC with chronic renal failure necessitating renal replacement therapy have not been published. The aim of the present study was to evaluate the incidence of end-stage renal disease (ESRD) from unilateral RCC, and to assess the associated pathology and possible pathogenic factors. In 1999, a survey of the 350 patients treated by chronic dialysis in Asturias, Spain, was carried out to identify and collect clinical information on patients with primary unilateral RCC whilst on their renal replacement programme. Seven patients were identified as having ESRD and unilateral RCC, giving an incidence of 2% of patients treated by dialysis. There was a wide spectrum of associated disease and clinical presentation. All patients underwent radical or partial nephrectomy and were free of recurrence 6--64 months after surgery. Six patients were alive and free of malignancy recurrence for 6--30 months after the onset of haemodialysis. ESRD is rare in association with unilateral RCC, but does contribute to significant morbidity. However, the data presented here are encouraging and suggest that cancer-free survival with renal replacement therapy can be achieved in such patients.

    The aim of this study was to test the hypothesis that experimental and reversible changes of occlusion affect the levels of surface electromyographic (SEMG) activity in the anterior temporalis and masseter areas during unilateral maximal voluntary biting (MVB) in centric and eccentric position. Changes were achieved by letting 21 healthy subjects bite with and without a cotton roll between the teeth. The placement alternated between sides and between premolar and molar areas. The SEMG activity level was lower when biting in eccentric position without than with a cotton roll between teeth (P 0.05). In the anterior temporalis area, the balancing side SEMG activity was lower in eccentric than in centric but only in molar-supported biting (P = 0.026). These results support that the masseter and anterior temporalis muscles have different roles in keeping the mandible in balance during unilateral supported MVB. Changes in occlusal stability achieved by biting with versus without a cotton roll were found to affect the SEMG activity levels.

    Anterior plagiocephaly is a premature closing of unilateral coronal suture. This premature suture fusion causes a series of cranial asymmetry and alteration of the fronto-orbital region.The authors described a new surgical technique to correct the facial asymmetry that reduces the operative time and the possible complications.In a period between 2013and 2016, 12 children affected by nonsyndromic anterior plagiocephaly were treated with this new procedure.Clinical, cranial development, and absence of postoperative complication demonstrated that one-wing surgical bone correction is a useful and innovative technique.

  17. Unilateral aplasia of both cruciate ligaments

    2010-02-01

    Full Text Available Abstract Aplasia of both cruciate ligaments is a rare congenital disorder. A 28-year-old male presented with pain and the feeling of instability of his right knee after trauma. The provided MRI and previous arthroscopy reports did not indicate any abnormalities except cruciate ligament tears. He was referred to us for reconstruction of both cruciate ligaments. The patient again underwent arthroscopy which revealed a hypoplasia of the medial trochlea and an extremely narrow intercondylar notch. The tibia revealed a missing anterior cruciate ligament (ACL footprint and a single bump with a complete coverage with articular cartilage. There was no room for an ACL graft. A posterior cruciate ligament could not be identified. The procedure was ended since a ligament reconstruction did not appear reasonable. A significant notch plasty if not a partial resection of the condyles would have been necessary to implant a ligament graft. It is most likely that this would not lead to good knee stability. If the surgeon would have retrieved the contralateral hamstrings at the beginning of the planned ligament reconstruction a significant damage would have occurred to the patient. Even in seemingly clear diagnostic findings the arthroscopic surgeon should take this rare abdnormality into consideration and be familiar with the respective radiological findings. We refer the abnormal finding of only one tibial spine to as the "dromedar-sign" as opposed to the two (medial and a lateral tibial spines in a normal knee. This may be used as a hint for aplasia of the cruciate ligaments.

    Commarmond, J

    2001-04-01

    We assessed the relative advantages of unilateral versus bilateral posterior approaches for lumbar spine fusion. Eighty-three patients who underwent lumbar spine fusion via a bilateral posterior approach and who had reached more than two years follow-up were compared with 80 patients who had undergone the same procedure via a unilateral posterior approach, including 54 with a follow-up greater than one year and 24 greater than two years. Most cases were L4-L5 fusions for degenerative spondylolisthesis or recurrent discal herniation with instability. Two composite carbon cages were filled with autologous cancellous bone. The key to the unilateral approach was the comfortable exposure of the disc by lamino-arthectomy; the osteosynthesis could then be performed unilaterally if only one gutter was opened. We measured bleeding and operative time to quantify surgical difficulty. At one year we assessed disc height, lordosis, frontal balance, and fusion of the operated disk. At two years, we assessed lombalgia and sciatalgia [scored from 4 (none) to 0 (intolerable)], subjective outcome, and recovery of former activity level. Mean blood loss and operative time were 360 ml and 162 min for the 83 classical procedures and 216 ml and 118 min for the 80 unilateral procedures. There were ten dural wounds with the bilateral approach and one dural wound and one transient radicular deficit with the unilateral approach. At one year, 81 of the 83 unilateral cases had reached fusion (2 nonunions). There was a mean 2 degrees gain in discal lordosis despite three cases of impaction due to osteoporosis. For the unilateral procedures, all 54 reached fusion at one year with a mean 2.5 degrees gain in lordosis, also with 3 impactions. With intersomatic distraction, balanced disc height in the frontal plane was obtained in all cases where the initial narrowing was not excessive. There were no cases of posterior displacement. There was a degradation of the supra-adjacent segment in three of

    Yu-Chieh Wang

    2013-06-01

    Conclusion: In this study, we successfully demonstrated that our IVPCA protocol can provide adequate analgesia for patients after both bilateral and unilateral TKA. However, sedation, nausea, and vomiting occurred more frequently during the postoperative 24–48-hour period in patients who underwent bilateral than unilateral TKA. This may due of the increased number of bolus doses administered to the patients in the bilateral TKA group during the postoperative 12–18, 18–24, and 30–36-hour periods. Therefore, the initial infusion rates for patients undergoing bilateral TKA could be set at a lower threshold in order to reduce the incidence of these side effects.

  20. Eyelid Retraction in Isolated Unilateral Congenital Blepharoptosis

    Directory of Open Access Journals (Sweden)

    Michael S. Salman

    2017-05-01

    Full Text Available Isolated unilateral congenital ptosis is encountered relatively infrequently in clinical practice. It typically consists of a unilateral droopy eyelid, weak levator palpebrae superioris muscle function, lid lag, and an absent upper lid crease with no other abnormalities on examination. We present a four-and-a-half-year-old girl with isolated and mild unilateral congenital ptosis who unexpectedly demonstrated a static upper eyelid on downgaze in conjunction with a well-formed upper lid skin crease. We attribute this uncommon sign in congenital ptosis to stiffness and presumed fibrosis of the levator muscle. Examining the function of the eyelids in all directions of gaze is important in patients with abnormalities of lid position, since additional useful information can be gleaned about the status of the levator muscle including, aberrant regeneration or fibrosis.

    The purpose of this present study was to examine contralateral ACL injury cases after ACL reconstruction, to determine the characteristics of such injuries. We performed a retrospective analysis of 24 patients with contralateral ACL injury after ACL reconstruction. The control group consisted of 200 cases with unilateral ACL injury. The following were examined in the contralateral group: timing of the contralateral ACL injury, and the situations of the initial and contralateral ACL injuries. The following items were compared between the contralateral and control groups: age at the time of initial injury, level of competitive sports using Tegner activity scores, knee anterior laxity (KT-1000), and the ratio (%) of affected to unaffected legs in the strengths of the knee extensor and flexor muscles 6 months after surgery. Examination of injury situations showed that approximately 70% of the contralateral group was injured in situations similar to those at their initial injuries. There were no significant differences between the two groups in age at the time of initial injury , Tegner activity scores, knee anterior laxity, and the strengths of the knee extensor, flexor muscles and H/Q ratio 6 months after reconstruction. But, the age at the time of initial injury trended to be low in contralateral group. Knee anterior laxity and muscle weakness of the reconstructed legs six months following surgery were not individually related to contralateral ACL injury occurring approximately two years after surgery.

    The determination of language dominance as part of the presurgical workup of patients with pharmacoresistant epilepsies has experienced fundamental changes. With the introduction of noninvasive functional magnetic resonance imaging (fMRI), the number of patients receiving intracarotid amobarbital procedures (IAPs) for assessment of language dominance has decreased considerably. However, recent studies show that because of methodologic limitations of fMRI, IAP remains an important tool for language lateralization. The current study examines whether unilateral instead of bilateral IAP is an adequate way to apply IAP with reduced invasiveness. We retrospectively examine the predictive value of unilateral IAP for the results of bilateral IAP based on a sample of 75 patients with various types of language dominance. Target parameters are the prediction of the language-dominant hemisphere and the identification of patients with atypical language dominance. For language assessment based on unilateral IAP, we introduce the measure hemispheric language capacity (HLC). Unilateral IAP performed on the side of intended surgery quantifies language capacity contralateral to the intended surgery. It detects atypical (bilateral or right) language dominance in the majority of patients. Experience with a separate series of 107 patients requiring presurgical language lateralization shows that in >80%, bilateral IAPs are redundant. Unilateral IAP is principally sufficient for language lateralization in the presurgical evaluation of patients with pharmacoresistant epilepsies. Necessity of bilateral IAP is restricted to few indications (e.g., callosotomy). In times of noninvasive language lateralization, we propose unilateral IAP as the method of choice for the verification of doubtful (bilateral) fMRI activation patterns.

    Superior oblique palsy is accompanied in most cases by overaction of the muscle's ipsilateral antagonist, the inferior oblique muscle. Overaction and contracture of the ipsilateral superior rectus muscle in patients with unilateral fourth (trochlear) nerve palsy is seldom discussed in the literature. The purpose of this study is to evaluate the frequency of superior rectus muscle overaction/contracture syndrome in patients with unilateral trochlear nerve palsy. The records of 198 patients with unilateral trochlear nerve palsy examined by the authors between July 1987 and July 2008 were reviewed retrospectively. All patients underwent complete eye examination with measurement of the deviation in the 9 positions of gaze and with the head tilted to both sides in all cooperative patients. Selection criteria for superior rectus muscle overaction/contracture syndrome in these patients were as follows: vertical deviation of 15(Delta) or larger in primary position, equal or larger hypertropia with the ipsilateral forced tilt test than with the eyes looking straight ahead, more than 5(Delta) hypertropia of the affected eye in horizontal gaze to the same side, hypertropia in all upgazes, and overaction of the contralateral superior oblique muscle. Of 198 patients, 33 (16.6%) met the selection criteria for superior rectus muscle overaction/contracture syndrome. Superior rectus muscle overaction/contracture syndrome frequently occurs in unilateral superior oblique palsy.

    The aim of the present study was to demonstrate that the positivity of nonspecific immunological tests could be found not only in bilateral hearing loss but also in unilateral cases, either sudden or progressive. An observational case series study included subjects suffering from unilateral or bilateral, sudden or progressive, symmetric or asymmetric sensorineural hearing loss (SNHL). All the patients underwent pure tone audiometry and the following battery of blood exams: anti-nuclear antibody (ANA), extractable nuclear antigen (ENA) antibody screening, anti-thyroperoxidase (anti-TPO), anti-thyroglobulin and anti-smooth muscle antibody (ASMA). The positivity to nonspecific immunological test was found in nearly 70% of the study groups. ASMA and ANA were found to be present in both bilateral and unilateral cases, without statistical difference. Considering the correlation between positivity/negativity and systemic autoimmune pathologies, in the bilateral forms of hearing loss, a high incidence of thyroid pathologies has been identified, with a higher percentage of systemic autoimmune diseases in respect to the normal population. The nonspecific autoimmune tests are worth to be performed also when SNHL is not bilateral and progressive, since an immunological mechanism could also underlie unilateral and sudden SNHL cases.

    Objective: To evaluate the clinical value of electron beam CT (EBCT) in diagnosing congenital unilateral absence of pulmonary artery (UAPA). Methods: Patients with clinically suspected pulmonary artery disease or primary pulmonary hypertension underwent EBCT scanning. EBCT confirmed the diagnosis of UAPA in 11 patients, who were also evaluated with echocardiography and chest roentgenography. Cardioangiography and nuclear ventilation-perfusion scan were performed in some patients for a comparative study. Results: 4 female adults had UAPA with out associated congenital anomaly. 3 male children with coexisting complex congenital abnormality had unilateral absence of the left pulmonary artery and 4 patients coexisted other simple cardiovascular anomaly. EBCT scanning simultaneously displayed topographic pattern of both unilateral absence of pulmonary artery and coexisting congenital cardiovascular anomaly, as well as lung diseases. Conclusion: UAPA diagnosed in childhood usually has unilateral absence of the left pulmonary artery and associated congenital cardiovascular anomaly, while UAPA diagnosed in adult usually has UAPA on the right side without associated congenital anomaly. EBCT is one of the optimal imaging techniques in diagnosing UAPA and it greatly increases the diagnostic efficacy than echocardiography dose. Both EBCT and cardioangiography have their own advantages, however, EBCT, as a noninvasive method, should be complementary and not exclusive

    Study Design Controlled laboratory study. Background Anterior cruciate ligament (ACL) injury may result in neuroplastic changes due to lost mechanoreceptors of the ACL and compensations in neuromuscular control. These alterations are not completely understood. Assessing brain function after ACL injury and anterior cruciate ligament reconstruction (ACLR) with functional magnetic resonance imaging provides a means to address this gap in knowledge. Objective To compare differences in brain activation during knee flexion/extension in persons who have undergone ACLR and in matched controls. Methods Fifteen participants who had undergone left ACLR (38.13 ± 27.16 months postsurgery) and 15 healthy controls matched on age, sex, height, mass, extremity dominance, education level, sport participation, and physical activity level participated. Functional magnetic resonance imaging data were obtained during a unilateral knee motor task consisting of repeated cycles of knee flexion and extension. Results Participants who had undergone ACLR had increased activation in the contralateral motor cortex, lingual gyrus, and ipsilateral secondary somatosensory area and diminished activation in the ipsilateral motor cortex and cerebellum when compared to healthy matched controls. Conclusion Brain activation for knee flexion/extension motion may be altered following ACLR. The ACLR brain activation profile may indicate a shift toward a visual-motor strategy as opposed to a sensory-motor strategy to engage in knee movement. Level of Evidence Cohort, level 3.

    To present the experience of the Orthopedics Service PEMEX South Central Hospital in the management of anterior unidirectional shoulder instability with an arthroscopic technique consisting of capsular retensioning either combined with other anatomical repair procedures or alone. Thirty-one patients with anterior unidirectional shoulder instability operated-on between January 1999 and December 2005 were included. Fourteen patients underwent capsular retensioning and radiofrequency, and in 17 patients, capsular retensioning was combined with suture anchors. Patients with a history of relapsing glenohumeral dislocations and subluxations, with anterior instability with or without associated Bankart lesions were selected; all of them were young. The results were assessed considering basically the occurrence of instability during the postoperative follow-up. No cases of recurring instability occurred. Two cases had neuroma and one experienced irritation of the suture site. Six patients had residual limitation of combined lateral rotation and abduction movements, of a mean of 10 degrees compared with the healthy contralateral side. The most frequent incident was the leak of solutions to the soft tissues. Capsular retensioning, whether combined or not with other anatomical repair techniques, has proven to result in a highly satisfactory rate of glenohumeral stabilization in cases of anterior unidirectional instabilities. The arthroscopic approach offers the well-known advantages of causing less damage to the soft tissues, and a shorter time to starting rehabilitation therapy and exercises.

    Aim: To highlight the variation in clinical manifestations, imaging and management of four cases of unilateral pulmonary artery agenesis presenting in adulthood. Method: Four patients with unilateral pulmonary artery agenesis were referred to our institution between 1995 and 2005. They underwent a series of investigations, including chest radiography, echocardiography, ventilation perfusion scintigraphy, angiography, computed tomography (CT) and magnetic resonance imaging (MRI). Results: Two of the four patients had absence of the right main pulmonary artery, whilst the remaining two patients had absence of the left main pulmonary artery. One patient showed a restrictive defect on pulmonary function tests. Two patients who had ventilation perfusion scintigraphy showed absent perfusion and reduced ventilation on the affected side. Angiography (where performed), CT and MRI confirmed the anatomy and the presence of multiple collaterals. Bronchiectasis was demonstrated on CT in two patients, with one also demonstrating a mosaic attenuation pattern. One patient had an incidental lung tumour on the side of the agenesis, which was diagnosed as a chondroid hamartoma on histology. Three of the four patients eventually underwent resection of the affected lung. Conclusion: Isolated unilateral pulmonary artery agenesis has a non-specific presentation. Awareness of this condition can lead to earlier diagnosis, with cross-sectional imaging making an important contribution

    The gold standard of treatment for esthesioneuroblastoma consists of en bloc craniofacial resection with postoperative therapy dictated by histology and tumor extent. Numerous studies have shown fully endoscopic approaches to provide comparable survival and recurrence rates with decreased patient morbidity. Here we report the first multi-institutional series assessing smell outcomes of patients who underwent unilateral endoscopic resection of esthesioneuroblastoma with preservation of the contralateral olfactory bulb. A multi-institutional retrospective review was performed identifying patients who underwent endoscopic unilateral resection of esthesioneuroblastoma with preservation of 1 olfactory bulb between 2003 and 2015. After completion of postoperative radiation, patients were administered the University of Pennsylvania Smell Identification Test (UPSIT) to assess olfactory function. Fourteen patients (7 males, 7 females) were identified and tested for posttreatment olfactory function. All 14 patients received postoperative radiotherapy and 4 patients received additional chemotherapy. Mean follow-up time was 51.7 months. There was no disease recurrence. Six patients (43%) were found to have residual smell function with 2 patients (14%) having normal or mildly reduced smell function. Here we report the first multi-institutional series demonstrating smell preservation after unilateral endoscopic resection of esthesioneuroblastoma. In carefully selected patients, this approach can yield comparable survival with decreased patient morbidity. © 2016 ARS-AAOA, LLC.

  20. Unilateral vestibular loss impairs external space representation.

    Directory of Open Access Journals (Sweden)

    Liliane Borel

    Full Text Available The vestibular system is responsible for a wide range of postural and oculomotor functions and maintains an internal, updated representation of the position and movement of the head in space. In this study, we assessed whether unilateral vestibular loss affects external space representation. Patients with Menière's disease and healthy participants were instructed to point to memorized targets in near (peripersonal and far (extrapersonal spaces in the absence or presence of a visual background. These individuals were also required to estimate their body pointing direction. Menière's disease patients were tested before unilateral vestibular neurotomy and during the recovery period (one week and one month after the operation, and healthy participants were tested at similar times. Unilateral vestibular loss impaired the representation of both the external space and the body pointing direction: in the dark, the configuration of perceived targets was shifted toward the lesioned side and compressed toward the contralesioned hemifield, with higher pointing error in the near space. Performance varied according to the time elapsed after neurotomy: deficits were stronger during the early stages, while gradual compensation occurred subsequently. These findings provide the first demonstration of the critical role of vestibular signals in the representation of external space and of body pointing direction in the early stages after unilateral vestibular loss.

    2017-06-01

    Conventional paper-and-pencil tests of unilateral neglect are of limited ecological validity. To address this issue, a number of assessment procedures have been proposed to provide clinicians and researchers with more ecologically valid assessments of unilateral neglect, which may be useful to plan rehabilitation and to measure the generalization of the effects of rehabilitation to daily life. We present here an overview of the different assessment measures available in the literature. The most widely used scales are the Behavioural Inattention Test (BIT), the semi-structured scales for assessment of personal and extra-personal neglect, the Subjective Neglect Questionnaire, the Baking Tray Task, the wheelchair obstacle course, the ADL-based neglect battery, and the Catherine Bergego Scale (CBS). The CBS is probably, to date, the most widely used behavioural assessment instrument for unilateral neglect. It has been found to be reliable, valid, and sensitive to change during rehabilitation. It also enables the assessment of awareness of the consequences of unilateral neglect in daily life skills. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Undescended testes are the most common urogenital malformation in boys. Impaired microcirculation is among other factors addressed as a potential complication of surgery and scar formation, leading to long-term suboptimal results. Our aim was to compare the postoperative microcirculation in operated versus non-operated contralateral testis groups after unilateral orchiopexies versus a healthy control cohort. Ninety-nine consecutive patients were included after unilateral orchiopexy procedures at the age of 3.5 years (±2.9 years) at a single center for pediatric surgery. Eight-five patients were examined with a combination of laser Doppler (blood flow determination) and white-light spectroscopy (oxygen saturation and hemoglobin amount determinations) to determine the microcirculation at two different depth levels non-invasively. All relevant surgery data were obtained retrospectively. The right side was operated in 53.5% of cases. Previous hormone treatment had been prescribed in 46.5%. There were no significant differences in perfusion measurements between patients with previous hormone therapy and patients without. There was no significant difference in age and clinical pubertal stage between groups; however, 65% of patients underwent surgery after their second birthday. When comparing oxygen saturation (So2), relative hemoglobin (rHb), flow, and velocity in the operated testis with the contralateral testis of the same patients, we found significantly higher flows and velocities for the contralateral testes (p = 0.041, p = 0.022). Similar higher flows and velocities were found in the healthy controls (p problem for both testes in the affected patients. Copyright © 2015 Journal of Pediatric Urology Company.

    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.

    2016-09-01

    To measure and compare the amount of anterior tibial subluxation (ATS) after anatomic ACL reconstruction for both acute and chronic ACL-deficient patients. Fifty-two patients were clinically and radiographically evaluated after primary, unilateral, anatomic ACL reconstruction. Post-operative true lateral radiographs were obtained of both knees with the patient in supine position and knees in full passive extension with heels on a standardized bolster. ATS was measured on the radiographs by two independent and blinded observers. ATS was calculated as the side-to-side difference in tibial position relative to the femur. An independent t test was used to compare ATS between those undergoing anatomic reconstruction for an acute versus chronic ACL injury. Chronic ACL deficiency was defined as more than 12 weeks from injury to surgery. Patients averaged 26.4 ± 11.5 years (mean ± SD) of age, 43.6 % were female, and 48.1 % suffered an injury of the left knee. There were 30 and 22 patients in the acute and chronic groups, respectively. The median duration from injury to reconstruction for the acute group was 5 versus 31 weeks for the chronic group. After anatomic ACL reconstruction, the mean ATS was 1.0 ± 2.1 mm. There was no statistical difference in ATS between the acute and chronic groups (1.2 ± 2.0 vs. 0.6 ± 2.3 mm, n.s.). Assessment of inter-tester reliability for radiographic evaluation of ATS revealed an excellent intraclass correlation coefficient of 0.894. Anatomic ACL reconstruction reduces ATS with a mean difference of 1.0 mm from the healthy contralateral limb. This study did not find a statistical difference in ATS between patients after anatomic ACL reconstruction in the acute or chronic phase. These observations suggest that anatomic ACL reconstruction, performed in either the acute or the chronic phase, approaches the normal AP relationship of the tibiofemoral joint. IV.

  11. Modification of unilateral otolith responses following spaceflight.

    2015-12-01

    The aim of the study was to resolve the issue of spaceflight-induced, adaptive modification of the otolith system by measuring unilateral otolith responses in a pre- versus post-flight design. The study represents the first comprehensive approach to examining unilateral otolith function following space flight. Ten astronauts participated in unilateral otolith function tests three times preflight and up to four times after Shuttle flights from landing day through the subsequent 10 days. During unilateral centrifugation, utricular function was examined by the perceptual changes reflected by the subjective visual vertical (SVV) and the otolith-mediated ocular counter-roll, designated as utriculo-ocular response (UOR). Unilateral saccular reflexes were recorded by measurement of collic vestibular evoked myogenic potentials (cVEMP). The findings demonstrate a general increase in interlabyrinth asymmetry of otolith responses on landing day relative to preflight baseline, with subsequent reversal in asymmetry within 2-3 days. Recovery to baseline levels was achieved within 10 days. This fluctuation in asymmetry was consistent for the utricle tests (SVV and UOR) while apparently stronger for SVV. A similar asymmetry was observed during cVEMP testing. In addition, the results provide initial evidence of a dominant labyrinth. The findings require reconsideration of the otolith asymmetry hypothesis; in general, on landing day, the response from one labyrinth was equivalent to preflight values, while the other showed considerable discrepancy. The finding that one otolith response can return to one-g level within hours after re-entry while the other takes considerably longer demonstrates the importance of considering the otolith response as a result of both peripheral and associated central neural processing.

    2015-05-01

    A 61 year-old man presented with progressive shortness of breath. Computed tomography scan of the chest showed diffuse ground glass infiltrates and dilated pulmonary vessels in the right lung in addition to bilateral pulmonary masses with obstruction of the left main pulmonary bronchus. The patient underwent bronchoscopy with destruction of the tumor obstructing the left main pulmonary bronchus, resulting in clinical improvement and resolution of the right pulmonary infiltrates. We hypothesize that the patient developed right pulmonary edema secondary to hypoxic vasoconstriction of the left lung. This case suggests a rare mechanism of unilateral pulmonary edema and supports inclusion of pulmonary edema in the differential diagnosis of unilateral pulmonary infiltrates in the setting of contralateral bronchial obstruction.

    2008-05-01

    The purpose of this study was to investigate the relationship between soft-tissue and underlying skeletal structures before and after unilateral mandibular distraction osteogenesis. The sample consisted of 11 patients (three girls and eight boys) with an average age of 4.6 years at the time of treatment. All patients had unilateral craniofacial microsomia (four right-sided and seven left-sided unilateral craniofacial microsomia) and all underwent unilateral mandibular distraction osteogenesis. Measurements were performed on frontal medical photographs and posteroanterior cephalograms at predistraction (time 1) and postdistraction (time 2) periods. Left and right ramus heights, skeletal midline deviation, and transverse occlusal plane were measured on the posteroanterior cephalograms and compared with the linear distances between the lip commissures and the orbital plane, the circumference of both sides of the faces, and the angulation of the oral commissure plane as recorded on the medical photographs, respectively. To reduce magnification error, ratios of affected to less affected sides of the mandibles and soft-tissue facial structures were selected and studied. A similar relationship was observed between soft-tissue and skeletal components. However, there was no 1:1 relationship between the changes in ramus height and improvement in parallelism of lip commissures to the orbital plane. A significant improvement in soft- and hard-tissue anatomy has been observed following unilateral distraction osteogenesis of the mandible. The relationship between the soft-tissue and skeletal correction was different for all patients because of the large range in severity of the craniofacial malformation. Greater skeletal deficiency requires more correction to achieve symmetry of both hard and soft tissue.

    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

    2010-01-01

    Purpose: Hemiablative therapy (HAT) is increasing in popularity for treatment of patients with low-risk prostate cancer (PCa). The validity of this therapeutic modality, which exclusively treats PCa within a single prostate lobe, rests on accurate staging. We tested the accuracy of unilaterally unremarkable biopsy findings in cases of low-risk PCa patients who are potential candidates for HAT. Methods and Materials: The study population consisted of 243 men with clinical stage ≤T2a, a prostate-specific antigen (PSA) concentration of <10 ng/ml, a biopsy-proven Gleason sum of ≤6, and a maximum of 2 ipsilateral positive biopsy results out of 10 or more cores. All men underwent a radical prostatectomy, and pathology stage was used as the gold standard. Univariable and multivariable logistic regression models were tested for significant predictors of unilateral, organ-confined PCa. These predictors consisted of PSA, %fPSA (defined as the quotient of free [uncomplexed] PSA divided by the total PSA), clinical stage (T2a vs. T1c), gland volume, and number of positive biopsy cores (2 vs. 1). Results: Despite unilateral stage at biopsy, bilateral or even non-organ-confined PCa was reported in 64% of all patients. In multivariable analyses, no variable could clearly and independently predict the presence of unilateral PCa. This was reflected in an overall accuracy of 58% (95% confidence interval, 50.6-65.8%). Conclusions: Two-thirds of patients with unilateral low-risk PCa, confirmed by clinical stage and biopsy findings, have bilateral or non-organ-confined PCa at radical prostatectomy. This alarming finding questions the safety and validity of HAT.

    Full Text Available BackgroundFinancial, clinical, and psychological considerations have made same-day surgery an attractive option for a variety of procedures. This article aimed to analyse the postoperative results of same-day primary unilateral cleft nasolabial repair.MethodsThis study was performed from 2011 to 2014. Unilateral cleft lip patients fulfilling the inclusion criteria were preoperatively classified as mild, moderate, and severe. All patients underwent same-day surgery and were discharged after satisfying the appropriate clinical criteria, receiving thorough counselling, and the establishment of a means of communication by phone. Postoperative outcomes were assessed and stratified according to preoperative severity and the type of repair.ResultsA total of 423 primary unilateral cleft lip patients were included. Fisher's anatomical subunit approximation technique was the most common procedure, followed by Noordhoff's technique. The postoperative outcome was good in 89.8% of cases, fair in 9.9% of cases, and poor in 0.2% of cases. The complication rate was 1.18% (n=5, and no instances of mortality were observed. The average hospital stay was 7.5 hours, leading to a cost reduction of 19% in comparison with patients who stayed overnight for observation.ConclusionsMild unilateral cleft lip was the most common deformity for which Fisher's anatomical subunit approximation technique was performed in most of the cases, with satisfactory postoperative outcomes. Refinements in the cleft rhinoplasty techniques over the course of the study improved the results regarding cleft nasal symmetry. Single-day primary unilateral cleft cheiloplasty was found to be a cost-effective procedure that did not pose an additional risk of complications.

    Full Text Available The objective of this study is to highlight the possibility of dysphagia induced by anterior cervical osteophytes. When not diagnosed early this condition may be responsible for complications such as severe dysphagia and potential lung aspiration, especially in elderly patients. Analysis of a case report of a 72-year old woman who presented cervical pain and progressive dysphagia. Imaging studies have shown anterior cervical osteophytosis and multilevel degenerative changes in the cervical spine. The patient underwent surgical excision of the cervical anterior osteophytes (C4, C5 and C6 and C5/C6 arthrodesis through anterior approach. The postoperative period was uneventful and symptoms resolved within 2 weeks. Early diagnosis and treatment led to complete resolution, avoiding late and serious complications associated with this pathology in the geriatric population, especially severe and progressive dysphagia and risk of pulmonary aspiration, and the consequent morbidity and mortality associated. A multidisciplinary approach is essential for the correct assessment of this condition

    Full Text Available A 46-year-old male patient was referred to our clinic with complaints of diplopia and esotropia in his right eye that developed after a car accident. The patient had right esotropia in primary position and abduction of the right eye was totally limited. Primary deviation was over 40 prism diopters at near and distance. The patient was diagnosed with sixth nerve palsy and 18 months after trauma, he underwent right medial rectus muscle recession. Ten months after the first operation, full-thickness tendon transposition of the superior and inferior rectus muscles (with Foster suture was performed. On the first postoperative day, slit-lamp examination revealed corneal edema, 3+ cells in the anterior chamber and an irregular pupil. According to these findings, the diagnosis was anterior segment ischemia. Treatment with 0.1/5 mL topical dexamethasone drops (16 times/day, cyclopentolate hydrochloride drops (3 times/day and 20 mg oral fluocortolone (3 times/day was initiated. After 1 week of treatment, corneal edema regressed and the anterior chamber was clean. Topical and systemic steroid treatment was gradually discontinued. At postoperative 1 month, the patient was orthophoric and there were no pathologic symptoms besides the irregular pupil. Anterior segment ischemia is one of the most serious complications of strabismus surgery. Despite the fact that in most cases the only remaining sequel is an irregular pupil, serious circulation deficits could lead to phthisis bulbi. Clinical properties of anterior segment ischemia should be well recognized and in especially risky cases, preventative measures should be taken.

    Intracranial aneurysms are sometimes presented with visual symptoms by their rupture or direct compression of the optic nerve. It is because their prevalent sites are anatomically located close to the optic pathway. Anterior communicating artery is especially located in close proximity to optic nerve. Aneurysm arising in this area can produce visual symptoms according to their direction while the size is small. Clinical importance of visual symptoms presented by aneurysmal optic nerve compression is stressed in this study. Retrospective analysis of ruptured anterior communicating artery aneurysms compressing optic apparatus were carried out. Total 33 cases were enrolled in this study. Optic nerve compression of the aneurysms was confirmed by the surgical fields. In 33 cases among 351 cases of ruptured anterior communicating artery aneurysms treated surgically, from 1991 to 2000, the dome of aneurysm was compressed in optic pathway. In some cases, aneurysm impacted into the optic nerve that deep hollowness was found when the aneurysm sac was removed during operation. Among 33 cases, 10 cases presented with preoperative visual symptoms, such as visual dimness (5), unilateral visual field defect (2) or unilateral visual loss (3), 20 cases had no visual symptoms. Visual symptoms could not be checked in 3 cases due to the poor mental state. In 6 cases among 20 cases having no visual symptoms, optic nerve was deeply compressed by the dome of aneurysm which was seen in the surgical field. Of 10 patients who had visual symptoms, 8 showed improvement in visual symptoms within 6 months after clipping of aneurysms. In 2 cases, the visual symptoms did not recover. Anterior communicating artery aneurysm can cause visual symptoms by compressing the optic nerve or direct rupture to the optic nerve with focal hematoma formation. We emphasize that cerebral vascular study is highly recommended to detect intracranial aneurysm before its rupture in the case of normal CT findings with

    Rotational instability of the knee remains an issue after anterior cruciate ligament (ACL) reconstruction. Hypothesis/Purpose: The purpose was to evaluate the subjective and objective outcomes of combined reconstruction of the ACL and anterolateral ligament (ALL) of the knee. The hypothesis was that favorable outcomes can be achieved with this surgical procedure compared with isolated anatomic reconstruction of the ACL. Randomized controlled trial; Level of evidence, 2. One hundred ten patients with a unilateral ACL injury and high-grade pivot shift were randomly assigned to undergo either combined ACL and ALL reconstruction (group A) or isolated ACL reconstruction (group B). Preoperative and postoperative evaluations of the patients were conducted by obtaining history details, recording physical examination findings, measuring knee laxity using the KT-1000 arthrometer, and using validated outcome scores for the knee. P reconstruction was 1.3 mm, while the median result for isolated ACL reconstruction was 1.8 mm ( P reconstruction had anterior translation of greater than 5 mm at maximum pulling strength compared with their normal knees at final follow-up. On the other hand, 3 (6.0%) patients who underwent isolated ACL reconstruction had anterior translation of more than 5 mm. No serious complications were found in both groups. Combined ACL and ALL reconstruction was found to be effective in improving subjective and objective outcomes. Nevertheless, these findings were not significantly superior to isolated ACL reconstruction except for the instrumented knee laxity testing results. This might indicate that ALL reconstruction should not be performed routinely for patients undergoing ACL reconstruction.

    Reports about fluctuating olfactory deficits are rare, as are reports of unilateral olfactory loss. We present a case of unilateral anosmia with contralateral normosmia, presenting as rapidly fluctuating anosmia. The olfactory fluctuation occurred in sync with the average nasal cycle duration. Examination after nasal decongestion, formal smell testing, and imaging revealed unilateral, left-sided anosmia of sinonasal cause, with right-sided normosmia. We hypothesize that the nasal cycle induced transient anosmia when blocking the normosmic side. Fluctuating olfactory deficits might hide a unilateral olfactory loss and require additional unilateral testing and thorough workup. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    The purpose of this study was to evaluate patients requiring unilateral total temporomandibular joint (TMJ) reconstruction and the risk for development of postsurgical contralateral TMJ pain and dysfunction over time requiring subsequent contralateral total joint reconstruction. Long-term subjective and objective outcomes of unilateral TMJ reconstruction also were evaluated. Seventy patients underwent unilateral total joint reconstruction using a patient-fitted total joint prosthesis from a single private practice from 1990 through 2012. The inclusion criteria were 1) unilateral TMJ reconstruction with TMJ Concepts or Techmedica patient-fitted total joint prosthesis; 2) operation performed by 1 surgeon (L.M.W.); 3) minimum 12-month follow-up; and 4) adequate records. There were no specific exclusion criteria. The primary outcome variable was to evaluate the effects of unilateral TMJ reconstruction with a total joint prosthesis on the contralateral TMJ relative to development of pain and dysfunction requiring subsequent contralateral reconstruction with a total joint prosthesis. Secondary outcome variables for all patients included TMJ pain, facial pain, headaches, diet, disability, quality of life, maximum incisal opening (MIO), and lateral excursion movements after unilateral TMJ reconstruction with the patient-fitted total joint prosthesis. Student t test and Wilcoxon test were used for statistical analyses, with a P value less than .01 for statistical significance. Sixty-one of 70 patients (87%) met the inclusion criteria (47 women [77%] and 14 men [23%]; average age, 38 yr; age range, 11 to 69 yr; average follow-up, 44 months; range, 12 to 215 months). Eight of 61 patients (13%) subsequently required contralateral TMJ reconstruction with a total joint prosthesis related to contralateral pain, dysfunction, and arthritis, but all 8 (8 of 27 [29.6%]) had previous contralateral TMJ disc repositioning surgery. For the secondary outcomes, TMJ pain decreased 63

    All changes in the knee that appear after anterior cruciate ligament (ACL) lesion lead to difficulties in walking, running, jumping especially during sudden changes of the line of movement. This significantly impairs quality of life of these subjects and leads to decrease in physical activity. Knee injuries make 5% of all most severe acute sport injuries. The aim of the study was to determine strength of the thigh muscles in persons with unilateral rupture of the ACL and to evaluate potential bilateral differences between healthy and injured leg. This study involved 114 male athletes of different sport specialities with the clinical diagnosis of ACL rupture. Each subject had unilateral ACL rupture and the other leg was actually the control for this research. An isokinetic device was used to evaluate the muscle strength of thigh muscles. Testing was performed for two testing speeds, 60º/s and 180º/s. Data analysis showed a statistically significant difference (p hamstrings to quadriceps (H/Q) ratio we found the unilateral disbalance of thigh muscle strength in ACL leg. A high level of validity makes isokinetic dynamometry the method for evaluation of thigh muscles strength and leaves this field of research open for new studies in order to improve both diagnostic and rehabilitation of patients with the insufficient ACL.

    Many approaches to the anterior skull base have been reported. Frequently used are the pterional, the unilateral or bilateral frontobasal, the supraorbital and the frontolateral approach. Recently, endoscopic transnasal approaches have become more popular. The benefits of each approach has to be weighted against its complications and limitations. The aim of this study was to investigate if the anterior interhemispheric approach (AIA) could be a safe and effective alternative approach to tumorous and non-tumorous lesions of the anterior skull base. We screened the operative records of all patients with an anterior skull base lesion undergoing transcranial surgery. We have used the AIA in 61 patients. These were exclusively patients with either olfactory groove meningioma (OGM) (n = 43), ethmoidal dural arteriovenous fistula (dAVF) ( n = 6) or frontobasal fractures of the anterior midline with cerebrospinal fluid (CSF) leakage ( n = 12). Patient records were evaluated concerning accessibility of the lesion, realization of surgical aims (complete tumor removal, dAVF obliteration, closure of the dural tear), and approach related complications. The use of the AIA exclusively in OGMs, ethmoidal dAVFs and midline frontobasal fractures indicated that we considered lateralized frontobasal lesions not suitable to be treated successfully. If restricted to these three pathologies, the AIA is highly effective and safe. The surgical aim (complete tumor removal, complete dAVF occlusion, no rhinorrhea) was achieved in all patients. The complication rate was 11.5 % (wound infection (n = 2; 3.2 %), contusion of the genu of the corpus callosum, subdural hygroma, epileptic seizure, anosmia and asymptomatic bleed into the tumor cavity (n = 1 each). Only the contusion of the corpus callosum was directly related to the approach (1.6 %). Olfaction, if present before surgery, was preserved in all patients, except one (1.6 %). The AIA is an effective and a safe approach

    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

    Unilateral paralysis is rarely reported to be primary presentation of severe hypokalemia. We describe a 24-year-old woman who presented to the emergency department with sudden onset of right-sided weakness. Neurologic examination revealed diminished muscle strength and tendon reflexes over the right limbs. Computed tomography of the brain showed no organic brain lesion. However, laboratory data showed hypokalemia (K+ 2.0 mmol/L) with metabolic acidosis (HCO3 − 19 mmol/L). She needed a total of 260 mmol K+ to achieve complete recovery of muscle strength at a serum K+ level of 3.2 mmol/L and was proved to have distal renal tubular acidosis. Severe hypokalemia must be kept in mind as a cause of acute unilateral paralysis without organic lesions to avoid unnecessary examination and potentially life-threatening complications.

    Full Text Available Macromastia is a condition of abnormal enlargement of the breast in excess of the normal proportion. It can be unilateral or bilateral and generally manifest at puberty when secondary sexual characters start appearing. Other patients may develop this condition at the time of pregnancy (Gestational macromastia. We present a case of young unmarried girl having unilateral macromastia due to polymastia. Unique feature in this case has been presence of two nipple areola complexes over right breast mound, one at normal site and another just superior to the inframammary crease in the line of embryonic milk line. The affected breast was almost double the size of contra lateral breast. Besides she also had bilateral hypertrophy of axillary breasts. Vertical scar reduction mammaplasty along with excision of axillary breasts was successfully carried out with gratifying results.

    Full Text Available Unilateral nevoid telangiectasia (UNT is a rare cutaneous disorder characterized by superficial telangiectasias distributed unilaterally. UNT can be congenital or acquired. Acquired UNT may be seen during pregnancy, puberty, and in association with cirrhosis and hepatitis C. Besides, the disease has been reported in healthy individuals. In the etiology, elevated blood estrogen levels and/or increased estrogen and progesterone receptors in the involved skin are suggested to cause this disorder. Here, we present four male patients aged 26-33 years, without an identified underlying disease and an 18-year-old female hepatitis B carrier with diagnosis of acquired UNT. Since UNT is seen rarely, it is discussed in the light of the literature data.

    Epidermolytic ichthyosis (or epidermolytic hyperkeratosis) classically presents with erythroderma and increased fragility (blistering) at birth or soon thereafter. In later life, erythroderma and blistering improve gradually and the clinical picture is dominated by hyperkeratotic plaques in flexures and around joints. Linear epidermolytic hyperkeratosis is a unique, uncommon clinical variant and the absence of erythroderma and blistering are its hallmark. Linear lesions may be localized or generalized andunilateral or bilateral. Herein we report a 6-year-old girl with unilateral epidermolytic ichthyosis.

    Full Text Available Transverse maxillary deficiency may be associated with sagittal or vertical problems of the maxilla or mandible. It may contribute to unilateral or bilateral posterior crossbite, anterior dental crowding, and unesthetic black buccal corridors on smiling. An adequate transverse dimension is important for stable and proper functional occlusion. Surgically, assisted rapid palatal expansion has been the treatment of choice to resolve posterior crossbite in skeletally mature patients. The following case report presents an adult Class III skeletal patient with an anterior open bite and bilateral posterior crossbite which was treated by surgically assisted rapid maxillary expansion with satisfactory outcomes.

    Full Text Available We studied the clinical presentation and management of four patients with anterior urethral valves; a rare cause of urethral obstruction in male children. One patient presented antenatally with oligohydramnios, bilateral hydronephrosis and bladder thickening suggestive of an infravesical obstruction. Two other patients presented postnatally at 1 and 2 years of age, respectively, with poor stream of urine since birth. The fourth patient presented at 9 years with frequency and dysuria. Diagnosis was established on either micturating cystourethrogram (MCU (in 2 or on cystoscopy (in 2. All patients had cystoscopic ablation of the valves. One patient developed a postablation stricture that was resected with an end-to-end urethroplasty. He had an associated bilateral vesicoureteric junction (VUJ obstruction for which a bilateral ureteric reimplantation was done at the same time. On long-term follow-up, all patients demonstrated a good stream of urine. The renal function is normal. Patients are continent and free of urinary infections. Anterior urethral valves are rare obstructive lesions in male children. The degree of obstruction is variable, and so they may present with mild micturition difficulty or severe obstruction with hydroureteronephrosis and renal impairment. Hence, it is important to evaluate the anterior urethra in any male child with suspected infravesical obstruction. The diagnosis is established by MCU or cystoscopy and the treatment is always surgical, either a transurethral ablation or an open resection. The long-term prognosis is good.

    This study was undertaken to determine whether unilateral hallux valgus progresses unilaterally and to evaluate the demographics, etiologies, and radiographic findings associated with symptomatic unilateral hallux valgus deformities. Patients treated for hallux valgus between January 2004 and December 2008 were identified, and of these, 33 patients with unilateral deformities were enrolled. Progression of deformities in normal feet were evaluated at last follow-up visit, and the clinical information and radiographic measurements of those with a deformed normal foot or an unchanged normal foot were compared. Thirty-three patients (3.4%) had a unilateral hallux valgus deformity on preoperative radiographs. The mean length of follow up was 4.7 years (range, 2.4-11). Twenty-four cases had no deformity of the normal foot at last follow-up (the unchanged group), but 15 cases had developed hallux valgus deformity (the deformed group). No significant intergroup differences were found in terms of metatarsus adductus angle (P = .412), Meary angle (P = .771), talocalcaneal angle (P = 1.000), or calcaneal pitch angle (P = .267). However, members of the deformed group were significantly younger at disease onset (P = .045), exhibited a curved first metatarsal head (P = .046), and had a larger initial hallux valgus angle (P hallux valgus was found to be over 97.3%, and significant differences were found between the deformed and unchanged groups in terms of age of onset, metatarsal head shape, and hallux valgus angle.

    Rubella virus is involved in the pathogenesis of Fuchs heterochromic uveitis and almost all cases in Europe show an active antibody production in the aqueous humor against rubella virus. Herein we report a case of a fully vaccinated patient with common variable immunodeficiency who developed unilateral Fuchs heterochromic uveitis secondary to rubella virus which was proven by intraocular fluid examination. Awareness of rubella associated anterior uveitis should remain also in vaccinated patients, especially those without a fully competent immune system.

    BACKGROUND: Impaired joint position sense (JPS) has been shown in anterior cruciate ligament (ACL) deficient and osteoarthritic knees. The relation between JPS and function is uncertain. The aim of this study was to determine further if ACL deficient knees show abnormal JPS and the effect of exercise therapy on JPS, and also to assess the relation between JPS, functional stability, and strength. METHODS: Fifty patients (46 men and four women, mean age 26.3 years) with unilateral ACL deficient...

    We aimed to investigate factors related to the prevalence of anterior disc displacement without reduction (ADDwoR) and bony changes of the condylar head (bony changes) in the temporomandibular joints (TMJs) of patients with anterior open bite. Subjects are comprised of 36 preoperative patients (72 joints) with skeletal anterior open bite without facial asymmetry who had undergone orthognathic surgery at the Hokkaido University Hospital; magnetic resonance imaging of the TMJ and cephalometric analysis were performed before treatment. Logistic regression analysis was performed to clarify relationships among age, overbite, overjet, ANB angle, sella to nasion (SN) to mandibular plane angle (SN-MP angle), SN to ramus plane angle (GZN angle), gonial angle, and incidence of ADDwoR or bony changes in patients with anterior open bite. Fifteen patients had bilateral ADDwoR, and five patients had unilateral ADDwoR; 17 patients had bilateral bony changes, and five patients had unilateral bony changes. SN-MP angle was greater in 20 patients with ADDwoR than that in 16 patients without ADDwoR (p < 0.05). GZN angle was greater in the 20 patients showing bony changes than that in the 16 patients without bony changes (p < 0.05). In terms of dentofacial morphology, SN-MP angle appears to be associated with the incidence of ADDwoR, and GZN angle appears to be associated with bony changes in the TMJ.

    Full Text Available Abstract Background The incidence of undetected radiographically iatrogenic longitudinal splitting in the anterior cortex during intramedullary nailing of the femur has not been well documented. Methods Cadaveric study using nine pairs of fresh-frozen femora from adult cadavers. The nine pairs of femora underwent a standardized antegrade intramedullary nailing and the detection of iatrogenic lesions, if any, was performed macroscopically and by radiographic control. Results Longitudinal splitting in the anterior cortex was revealed in 5 of 18 cadaver femora macroscopically. Anterior splitting was not detectable in radiographic control. Conclusion Longitudinal splitting in the anterior cortex during intramedullary nailing of the femur cannot be detected radiographically.

    2017-01-01

    Full Text Available A 31-year-old healthy male underwent deep anterior lamellar keratoplasty with big-bubble technique for treatment of keratoconus in his right eye. One week after surgery, he presented with detachment of the endothelium-Descemet complex with formation of a double anterior chamber, despite the apparent absence of an intraoperative Descemet membrane rupture. A subsequent intervention with the intent to relocate the corneal graft button was not effective, because the detachment appeared again one day later. The authors hypothesized that, at the time of the stromal dissection with big bubble technique, a small amount of air penetrated into the anterior chamber, creating a false pathway through the trabecular meshwork. The aqueous humor then penetrated the graft flowing through the false pathway, causing the endothelium-Descemet detachment. The persistence of that pathway, even after the intervention of graft repositioning, caused the failure of the latter procedure and persistence of the double chamber. We decided to wait and observe. The double anterior chamber spontaneously resolved in approximately three months.

An anterior open bite therapy has long been considered a challenge to orthodontist. The prevalence of anterior openbite range from 3,5 % to 11% among various age and ethnic groups and it has been shown that approximately 17% of orthodontic patients have open bite. Stability of treatment result of anterior open bite with well-maintained results is difficult, because the combination of anteroposteriorly discrepancy with skeletal open bite requires the highest degree of diagnostic and clinical skill. The etiology is complex, potentially involving skeletal, dental and habitual factors. The importance of an anterior open bite therapy is to eliminate the cause of the open bite. Various treatment modalities for the correction of an anterior open bite have been proposed, orthognatic surgery and orthodontic camouflage treatment such as high

    Anterior communicating artery aneurysm is the most common form of intracranial aneurysm and subarachnoid haemorrhage (SAH) is the common presenting feature of anterior communicating artery aneurysms. In general, patients with SAH from anterior communicating artery aneurysm present with neurological deficit. We report an interesting case of a 60-year-old man who presented with acute monocular vision loss accompanied by periorbital pain without any neurological deficit, finally diagnosed with SAH from ruptured anterior communicating artery aneurysm. Five months after immediate craniotomy with aneurysm neck clipping, his visual acuity was improved to 20/63 with a pale optic disc appearance. Acute retrobulbar optic neuropathy may be the sole manifestation of SAH from ruptured anterior communicating artery aneurysm. Unilateral decrease of visual acuity with periorbital pain, in the absence of other neurological change, may be the initial and isolated sign.

    Anterior knee pain is a common complain in all ages athletes. It may be caused by a large variety of injuries. There is a continuum of diagnoses and most of the disorders are closely related. Repeated minor trauma and overuse play an important role for the development of lesions in Hoffa's pad, extensor mechanism, lateral and medial restrain structures or cartilage surface, however usually an increase or change of activity is referred. Although the direct relation of cartilage lesions, especially chondral, and pain is a subject of debate these lesions may be responsible of early osteoarthrosis and can determine athlete's prognosis. The anatomy and biomechanics of patellofemoral joint is complex and symptoms are often unspecific. Transient patellar dislocation has MR distinct features that provide evidence of prior dislocation and rules our complication. However, anterior knee pain more often is related to overuse and repeated minor trauma. Patella and quadriceps tendon have been also implicated in anterior knee pain, as well as lateral or medial restraint structures and Hoffa's pad. US and MR are excellent tools for the diagnosis of superficial tendons, the advantage of MR is that permits to rule out other sources of intraarticular derangements. Due to the complex anatomy and biomechanic of patellofemoral joint maltracking is not fully understood; plain films and CT allow the study of malalignment, new CT and MR kinematic studies have promising results but further studies are needed. Our purpose here is to describe how imaging techniques can be helpful in precisely defining the origin of the patient's complaint and thus improve understanding and management of these injuries.

    Full Text Available The anterior cingulate cortex (ACC has a role in attention, analysis of sensory information, error recognition, problem solving, detection of novelty, behavior, emotions, social relations, cognitive control, and regulation of visceral functions. This area is active whenever the individual feels some emotions, solves a problem, or analyzes the pros and cons of an action (if it is a right decision. Analogous areas are also found in higher mammals, especially whales, and they contain spindle neurons that enable complex social interactions. Disturbance of ACC activity is found in dementias, schizophrenia, depression, the obsessive-compulsive syndrome, and other neuropsychiatric diseases.

    This paper revisits the evidence on the impact of unilateral divorce laws on divorce rates in the United States. Most states switched from requiring mutual consent to allowing unilateral or no-fault divorce between 1970 and 1985, while the national divorce rate more than doubled after 1965. According to the Coase theorem, however, the legal shift should have had no effect on divorce rates.

    2001-03-01

    The vestibulo-ocular reflex (VOR) stabilizes gaze to permit clear vision during head movements. It has been supposed that VOR function might be inferred from dynamic visual acuity (DVA), the acuity during imposed head motion. We sought to determine effectiveness of DVA for detection and lateralization of unilateral vestibulopathy, using rigorous psychophysical methods. Seventeen normal and 11 unilaterally vestibulopathic subjects underwent measurement of optically best corrected DVA during head motion. A variable size letter "E" 6 m distant was displayed in oblique random orientations to determine binocular DVA by a computer controlled, forced choice method. Three types of whole-body yaw rotation were delivered by a servo-controlled chair synchronized with optotype presentation. Two types of motion were predictable: (1) steady-state 2.0-Hz rotation at 10-130 degrees/s peak velocity with repetitive optotype presentation only during head velocity exceeding 80% of peak; and (2) directionally predictable transients at peak accelerations of 1000, 1600 and 2800 degrees/s2 with optotype presentation for 300 ms. For neither of these predictable motions did DVA in vestibulopathic subjects significantly differ from normal, with suggestions from search coil recordings that this was due to predictive slow and saccadic eye movements. Unilaterally vestibulopathic subjects experienced a significant decrease in DVA from the static condition during ipsilesional rotation for all three peak head accelerations. Only during directionally unpredictable transients with 75 ms or 300 ms optotype presentation was the sensitivity of DVA in unilaterally vestibulopathic subjects significantly abnormal during ipsilesional rotation. The ipsilesional decrease in DVA with head motion was greater for 75 ms than 300 ms optotype presentation. Search coil recordings confirmed hypometric compensatory eye movements during DVA testing with unpredictable, ipsilesional rotation. Receiver

    Congenital Horner syndrome is a rare disorder that accounts for less than 5% of all cases of Horner syndrome. Like Horner syndrome in general, it consists primarily of ptosis, miosis, and anhidrosis. Congenital Horner syndrome may manifest some special features such as iris heterochromia since the sympathetic nervous system is an essential component for the development and maintenance of eye color. We present 3 cases of unilateral straight hair in association with congenital Horner syndrome in which the patients had straight hair ipsilateral to the Horner syndrome, whereas on the contralateral side, it was curly, and we discuss possible mechanisms for this phenomenon.

Gynecomastia was seen on the left side of the chest in 13 patients and on the right side in 10 patients. There were no complications. The specimens did not reveal any malignant causes. Conclusion: Although most cases gynecomastia are idiopathic and bilateral, there are instances that require special at- tention and should be given unilateral status. Detailed evaluation including physical examination, history of drug use and concomitant medical disorders should be considered. [Arch Clin Exp Surg 2016; 5(4.000: 206-210

    Unilateral pulmonary vein atresia is a rare congenital anomaly. Its symptoms begin to manifest in childhood and a broad spectrum of clinical severity has been described, ranging from asymptomatic, recurrent pulmonary infection, severe hemoptysis, to death. Only a few adult cases with this condition, with no or mild symptoms, have been reported. Pulmonary angiography has been typically used for definite diagnosis. However, pulmonary angiography may be replaced with the current developing multidetector CT. This report presents an adult case with mild symptoms, diagnosed by multidetector CT.

    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.

  1. Bilateral and unilateral ECT: effects on verbal and nonverbal memory.

    1978-11-01

    The memory loss associated with bilateral and nondominant unilateral ECT was assessed with verbal memory tests known to be sensitive to left temporal lobe dysfunction and with nonverbal memory tests known to be sensitive to right temporal lobe dysfunction. Bilateral ECT markedly impaired delayed retention of verbal and nonverbal material. Right unilateral ECT impaired delayed retention of nonverbal material without measurably affecting retention of verbal material. Nonverbal memory was affected less by right unilateral ECT than by bilateral ECT. These findings, taken together with a consideration of the clinical efficacy of the two types of treatment, make what appears to be a conclusive case for unilateral over bilateral ECT.

    We describe a simplified method to detect anterior lenticonus. Three eyes of 2 patients with anterior lenticonus, plus 16 eyes from 16 healthy controls underwent Scheimpflug imaging of their anterior segment with Pentacam. The anterior capsule apex angle was manually identified and automatically measured by AutoCAD. The mean angle was 173.06° (SD: 1.91) in healthy subjects, and 158.33° (SD: 3.05) in anterior lenticonus eyes. The angle obtained from patients was more than 3 SD steeper than those from healthy subjects. The apical angle calculation method seems to discriminate well between normal eyes and eyes suspected of having anterior lenticonus. Copyright © 2013 Sociedad Española de Oftalmología.

All subjects underwent videonystagmography or electronystagmography (VNG/ENG), vestibular evoked myogenic potentials (VEMPs), self-report measures of self-perceived dizziness disability/handicap (Dizziness Handicap Inventory), and tests of postural control (Neurocom Equitest). Subjects were categorized into one of four groups based on balance function test results. All variables were subjected to a multifactor analysis of variance (ANOVA). The Dizziness Handicap Inventory (DHI) total scores and equilibrium scores served as the dependent variables. Results showed that patients with abnormal unilateral saccular or inferior vestibular nerve function (i.e., abnormal cVEMP) demonstrated significantly impaired postural control when compared to normal participants. However, this group demonstrated significantly better postural stability when compared to the group with abnormal caloric responses alone and the group with abnormal caloric responses and abnormal cVEMP results. Patients with an abnormal cVEMP did not differ significantly on the DHI compared to the other two impaired groups. We interpret these findings as evidence that a significantly asymmetrical cVEMP in isolation negatively impacts performance on measures of postural control compared to normal subjects but not compared to patients with significant caloric weaknesses. However, patients with a unilaterally abnormal cVEMP do not differ from patients with significant caloric weaknesses in regard to self-perceived dizziness handicap. American Academy of Audiology.

    Although the anterior guidance in complete dentures is not really a guide, the arrangement of the anterior maxillary and mandibular prosthetic teeth, defines a propulsive line called the virtual anterior guidance, a part from the cinematic criterias. The influence of this guide on cuspal movement is superior, in all mandibular points, to the influence of the condylar pathway. If this line is not respected, the practitioner may have to do excessive grindings during occlusal adjustments.

    To determine the value of serial personal photographs in timing the onset of unilateral cataracts in children over 6 months of age. Personal photographs from children with unilateral cataracts who underwent cataract extraction and intraocular lens implantation when > or =6 months of age were reviewed. Photographs were evaluated for changes in the red reflex, which might indicate the presence of a cataract. Twelve children underwent cataract surgery at a mean age of 37 months. They were followed for a mean of 32 months. Ten children were diagnosed as having an acquired cataract by photographic review documenting a previously normal red reflex. The visual acuity in the affected eye of 4 of these children improved to > or =20/60. Cataracts were visible on photographs prior to clinical diagnosis in 6 patients, from 0.5 to 22 months prior to clinical diagnosis. Visual outcomes did not relate closely to the photographically documented duration of the cataract prior to treatment. Photographs were not helpful in timing the onset of cataract in 2 children due to the poor quality of the images. Serial personal photographs are sometimes helpful in determining whether cataracts are acquired. However, the usefulness of personal photographs alone in predicting the visual outcome after cataract surgery was limited in this small, retrospective study.

    The present invention provides a method for producing an anterior cruciate ligament ex vivo. The method comprises seeding pluripotent stem cells in a three dimensional matrix, anchoring the seeded matrix by attachment to two anchors, and culturing the cells within the matrix under conditions appropriate for cell growth and regeneration, while subjecting the matrix to one or more mechanical forces via movement of one or both of the attached anchors. Bone marrow stromal cells are preferably used as the pluripotent cells in the method. Suitable matrix materials are materials to which cells can adhere, such as a gel made from collagen type I. Suitable anchor materials are materials to which the matrix can attach, such as Goinopra coral and also demineralized bone. Optimally, the mechanical forces to which the matrix is subjected mimic mechanical stimuli experienced by an anterior cruciate ligament in vivo. This is accomplished by delivering the appropriate combination of tension, compression, torsion, and shear, to the matrix. The bioengineered ligament which is produced by this method is characterized by a cellular orientation and/or matrix crimp pattern in the direction of the applied mechanical forces, and also by the production of collagen type I, collagen type III, and fibronectin proteins along the axis of mechanical load produced by the mechanical forces. Optimally, the ligament produced has fiber bundles which are arranged into a helical organization. The method for producing an anterior cruciate ligament can be adapted to produce a wide range of tissue types ex vivo by adapting the anchor size and attachment sites to reflect the size of the specific type of tissue to be produced, and also adapting the specific combination of forces applied, to mimic the mechanical stimuli experienced in vivo by the specific type of tissue to be produced. The methods of the present invention can be further modified to incorporate other stimuli experienced in vivo by the

    GRNB® is a non-radiating power tool that allows the evaluation of the anterior tibial translation. The pressure exerted by the system against the patella and the body mass index (BMI) could affect the anterior tibial translation when we repeat the measurements in healthy knees. We retrospectively evaluated the measurements of anterior knee laxity in healthy knees carried out by the GNRB® in 69 consecutive patients who underwent anterior cruciate ligament (ACL) repair in the contralateral knee. Two measurements were carried out, the initial measurements (M1), and then repeated at a mean of seven months (M2) (4.9 to 13months). There were 38 women and 31 men with an average age of 31years. In healthy knees, the Mean average anterior translation was 5.4±4mm with an average patellar force of 35.8 at time M1. The average anterior translation was 4.9±4mm with an average patellar force of 47 at time M2. There was a significant difference between the measurements M1 and M2 (P<0.03). The tightening force was significantly different between the two sets of measurements (P<10-7). There was a negative correlation between the pressure applied on the patella and anterior knee laxity (P<0.01). The pressure force exerted on the patella during GNRB® affects the measurement of anterior laxity in healthy knees. This raises the problem of the reproducibility of the measurements during repeated examinations at different times. Copyright © 2017 Elsevier B.V. All rights reserved.

    To test for otolith asymmetries, several studies described horizontal translation of the body and head en bloc during fast vertical axis rotation. This stimulus causes one otolithic organ to rotate on-axis, and the other to experience centripetal acceleration. To test a new, more simple method of unilateral stimulation with head tilt and the body remaining on axis. During stationary and during 360 deg/s rotation, 12 healthy blindfolded subjects had their heads tilted 30 degrees sideways, positioning one otolithic organ on the axis of rotation after the other. The haptic subjective vertical (SV) was recorded several times by means of a manually adjustable rod. It was found that during stationary the SV tilted about 4 degrees on average in the direction of the head. During rotation, the SV tilted about 9 degrees on average. We therefore estimate the effect of eccentric otolith rotation to be 5 degrees on average. Tilt of the subjective vertical induced by head tilt during on-axis body rotation can provide a relatively uncomplicated alternative to test unilateral otolithic function as compared to body and head translation during rotation. Moreover, unlike eccentric rotation of the entire body, somatosensory cues are minimized by keeping the body fixed on axis and by subtracting the effect of head tilt per se.

    To determine the effect of vestibular rehabilitation on reduction of fall risk in individuals with unilateral vestibular hypofunction and to identify those factors that predict fall risk reduction. Retrospective chart review. Tertiary referral center. Forty-seven patients with unilateral vestibular hypofunction, aged 28 to 86 years, who were at risk for falls on initial assessment. All patients underwent vestibular rehabilitation including adaptation exercises, designed to improve gaze stability, and gait and balance exercises. Fall risk (Dynamic Gait Index), visual acuity during head movements (Dynamic Visual Acuity), and subjective complaints were measured initially, at 2-week intervals, and at completion of physical therapy. As a group, the patients had significantly reduced risk for falls (p older (> or = 65 yr) and younger (adults showed significant reductions in fall risk with vestibular rehabilitation (p older adults remained at risk for falls at discharge compared with young adults (45% versus 11%). Initial Dynamic Gait Index and Dynamic Visual Acuity scores predicted fall risk reduction in patients with unilateral vestibular hypofunction. A model was developed using initial Dynamic Gait Index and Dynamic Visual Acuity scores to predict fall risk reduction. Vestibular rehabilitation is effective in significantly reducing fall risk in individuals with unilateral vestibular deficit. The model predicts fall risk reduction with good sensitivity (77%) and specificity (90%).

    Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

    To investigate prevalence and risk factors of pelvic organ prolapse in women underwent routine gynecologic health care in Peking Union Medical College Hospital (PUMCH). From Jan. 2008 to Aug. 2009, 972 women underwent gynecological health care in PUMCH were enrolled in this study. Questionnaires and pelvic examinations were given. The pelvic organ prolapse quantitive examination (POP-Q) system was used as the assessment tool. (1) Among all participants, the mean ages were (42 ± 10) years (range 22 to 78 years), the mean height were (162 ± 5) cm (range 142 to 180 cm), and the mean weight were (59 ± 8) kg (range 42 to 91 kg). 83.8% (815/972) of women were multipara. The mean total vaginal length (TVL) of 972 women was 8.20 cm. No women met the standard of pelvic organ prolapse, while 35.5% (345/972) of women presented mild posterior vaginal descent and 96.7% (940/972) presented mild anterior vaginal descent, all of them were asymptomatic. (2) The length of genital hiatus (gh), TVL and C, D proximal to the hymen in nullipara were (2.26 ± 0.32), (8.08 ± 0.30), (-7.08 ± 0.24) and (-8.08 ± 0.30) cm, which were significantly less than (2.33 ± 0.39), (8.22 ± 0.35), (-7.14 ± 0.28) and (-8.22 ± 0.35) cm in multipara (P 0.05). However, those in women at group of 22 - 34 years and 35 - 49 years showed statistical difference when compared with women at group of more than 50 years (P < 0.05). When compared with women at group of 22 - 34 years, the incidence of posterior and anterior vaginal wall protrusion were increased (OR = 1.713, 3.765). (4) Menopause status was associated with severities of all kinds of descent (P < 0.05) and presence of posterior vaginal protrusion (OR = 3.354). Mild anterior and posterior vaginal descent by POP-Q were common among women in China. The risk of anterior vaginal descent is relatively higher than posterior vaginal descent. However, most of the women with descent are asymptomatic and need no treatment. The most important factors

    2016-08-01

    This study aimed to examine interlimb differences in muscle strength and sit-to-stand (STS) kinetics in persons who underwent unilateral total knee arthroplasty (TKA) and to determine whether knee pain, quadriceps or hip abductor weakness contributes to altered STS performance. It was hypothesized that the operated limb would have weaker muscles, lower mechanical loading and that operated knee pain and muscle strength symmetry would predict loading symmetry between limbs during STS. One hundred and forty-two patients, 6 or 12 months post-unilateral TKA, underwent 3D motion analysis (VICON) of the STS task and isometric strength testing of the quadriceps and hip abductors. Knee pain was also quantified using a question from the Knee Outcome Survey-Activities of Daily Living Scale. The operated limb had weaker quadriceps (P lower hip (P = 0.004) and knee extension moments (P lower vertical ground reaction forces (P strength symmetry were related to symmetry in knee extension moment (P strength symmetry was related to symmetry in vertical ground reaction forces (P = 0.03), 1 year after surgery. Patients with unilateral TKA unload the operated limb and shift the mechanical load to the joints of the contralateral limb even 1 year after surgery. Knee pain and quadriceps strength asymmetry may play a role in the asymmetrical loading during STS post-TKA. Clinicians should consider addressing these modifiable impairments to resolve the loading asymmetry. III.

    A 10-month-old boy is presented who had isolated unilateral absence of the right pulmonary artery. He suffered from hemoptysis and severe congestive heart failure. The patient underwent prosthetic anastomosis of the right to the main pulmonary artery. Although the hemodynamic response was favorable, his oxygenation did not improve due to diffuse pulmonary arteriovenous fistulae of the affected lung. The patient succumbed 3 months after operation due to massive uncontrollable hemoptysis from the right lung. Isolated unilateral absence of the pulmonary artery is a rare lesion. In our review of the world literature as of November 1976, 47 cases (including this report) of the unilateral absence of the pulmonary artery have been reported. Of these 25.5% had pulmonary hypertension and only 4 cases underwent successful repair of the lesion. Though repair of this defect can be carried out, the result may not be always gratifying. Our experience with this case has led us to consider a lung biopsy before proceeding to the surgical repair of the lesion. If the affected lung shows arteriovenous abnormalities the operation should not be recommended.

    To investigate and integrate anatomic and physiologic findings from a group of patients who present retinitis pigmentosa affecting just one eye and use this information to propose mechanisms of disease pathogenesis. This prospective cross-sectional study examined 5 patients, all female, from 8 to 60 years old. The study was conducted in 4 university hospitals. The patients were selected according to the characteristics of ocular involvement, notably unilateral presentation of similar anatomic and functional abnormalities. Full-field electroretinogram, fundus photography, fundus autofluorescence, infrared imaging, optical coherence tomography, and genetic testing were performed. Full-field electroretinogram showed unilateral decrease in amplitude and increase in implicit time; autofluorescence showed unilateral areas of decreased intensity. The USH2AW4149R mutation was confirmed in one patient. Imaging and functional testing are important in elucidating the unilateral pattern of the disease and in monitoring these individuals. Mosaicism or somatic mutation may cause unilateral genetic disease presentation.

  7. Structural and Anatomic Restoration of the Anterior Cruciate Ligament Is Associated With Less Cartilage Damage 1 Year After Surgery: Healing Ligament Properties Affect Cartilage Damage

    2017-01-01

    Background: Abnormal joint motion has been linked to joint arthrosis after anterior cruciate ligament (ACL) reconstruction. However, the relationships between the graft properties (ie, structural and anatomic) and extent of posttraumatic osteoarthritis are not well defined. Hypotheses: (1) The structural (tensile) and anatomic (area and alignment) properties of the reconstructed graft or repaired ACL correlate with the total cartilage lesion area 1 year after ACL surgery, and (2) side-to-side differences in anterior-posterior (AP) knee laxity correlate with the total cartilage lesion area 1 year postoperatively. Study Design: Controlled laboratory study. Methods: Sixteen minipigs underwent unilateral ACL transection and were randomly treated with ACL reconstruction or bridge-enhanced ACL repair. The tensile properties, cross-sectional area, and multiplanar alignment of the healing ACL or graft, AP knee laxity, and cartilage lesion areas were assessed 1 year after surgery. Results: In the reconstructed group, the normalized graft yield and maximum failure loads, cross-sectional area, sagittal and coronal elevation angles, and side-to-side differences in AP knee laxity at 60° of flexion were associated with the total cartilage lesion area 1 year after surgery (R 2 > 0.5, P 0.5, P ligament or graft and AP laxity values were closer to those of the contralateral ACL-intact knee. Reconstructed grafts had a significantly larger normalized cross-sectional area and sagittal elevation angle (more vertical) when compared with repaired ACLs (P < .02). Conclusion: The tensile properties, cross-sectional area, and multiplanar alignment of the healing ACLs or grafts and AP knee laxity in reconstructed knees were associated with the extent of tibiofemoral cartilage damage after ACL surgery. Clinical Relevance: These data highlight the need for novel ACL injury treatments that can restore the structural and anatomic properties of the torn ACL to those of the native ACL in an

    We report a case of an intractable fistula repaired by transsacral direct suture. A 65-year-old man underwent low anterior resection for rectal cancer. He subsequently underwent ileostomy due to anastomosis leakage. The fistula of the anastomosis persisted 3 months after surgery. He underwent surgery to repair the fistula using a transsacral approach. After removing the coccyx, the fistula in the postrectal space was exposed directly. The presence of the fistula was confirmed by an air leak test and was closed by direct suture. After 33 days, the patient underwent ileostomy closure.

    Despite improved results with surgical therapy for acute type A aortic dissection (ATAAD), there remains a lack of consensus regarding the optimal method of cerebral protection and circulation management during ATAAD. The purpose of this study is to determine whether in the setting of antegrade cerebral perfusion, moderate hypothermic circulatory arrest (MHCA) provides equivalent cerebral and visceral protection as deep hypothermic circulatory arrest (DHCA) for patients undergoing emergent ATAAD repair. A review of the Emory aortic surgery database from 2004 to 2014 identified 288 patients who underwent ATAAD with right axillary artery cannulation, unilateral selective antegrade cerebral perfusion (uSACP), and hypothermic circulatory arrest (HCA). In all, 88 patients underwent HCA at 24 °C or lower (DHCA), and 206 patients underwent HCA at more than 24 °C (MHCA). Major adverse outcomes of death, stroke, temporary neurologic dysfunction, and dialysis-dependent renal failure were examined. The groups were well matched for age and major comorbidities. The DHCA patients underwent HCA at lower temperatures (DHCA 21.6 ± 3.1 °C vs MHCA 27.4 ± 1.6 °C, p 0.05). Moderate HCA with uSACP is an effective circulation management strategy that provides excellent cerebral and visceral protection during emergent ATAAD repair. In the setting of antegrade cerebral perfusion, deep hypothermia does not provide any additional benefit. Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    The objective of this study was to test if patients with unilateral hip osteoarthritis (OA) show greater muscle activity asymmetry between their affected and non-affected limbs than healthy controls between their left and right limbs. Seventeen patients with unilateral hip OA (7 females, 10 males) and 17 age-matched healthy controls (7 females, 10 males) participated in this study. Both groups performed instrumented gait analysis at comparable speeds. Muscle activity was recorded simultaneously for the tibialis anterior (TA), gastrocnemius medialis (GM), vastus lateralis (VL), semitendinosus (ST), tensor fasciae latae (TFL), and gluteus medius (GLM) muscles. In hip OA patients, EMG data showed greater activity of the TA muscle in the non-affected limb, and greater TFL muscle activity in the affected limb. Compared to healthy controls, greater asymmetries between paired limbs were observed for the TA and GM muscles. Finally, the TFL muscle of the affected limb contributed more to the total limb muscle activity than did the non-affected limb. The observed alterations in TA and GM muscle activity in hip OA patients may be due to the greater peak braking and peak vertical forces measured in the non-affected limb. Contrary to this, greater TLF muscle activity of the affected limb indicates the demands put on stabilizing the hip during stance phase. Further studies are necessary to test whether leg length discrepancy affects muscle activation alterations between the affected and non-affected limb in unilateral hip OA patients.

    Objective: To explore the feasibility and safety of kyphoplasty via unilateral extrapedicular approach for the treatment of osteoporotic thoracic compression fractures. Methods: A total of 16 patients with painful osteoporotic thoracci fractures were treated by kyphoplasty via unilateral extrapedicular approach. Pain was measured using the self-reporting visual analogue scale (VAS) preoperatively, postoperatively and in the final follow-up. Disability was measured using the Oswestry disability index (ODI) preoperatively, postoperatively and in the final follow-up. The height of the compromised vertebral body, the kyphotic angle were measured preoperatively, postoperatively and in the final follow-up. Results: Operations were completed smoothly, with the exception of 1 patients with less cement leakage but there was no clinical symptom occurred. The other one had intercostal neuralgia. Relief of pain was achieved in 24 hours post-operation. The mean operation time was 31minutes and the mean fluoroscopic time was 19.1. And the mean VAS score of these patients decreased from 8.2 ± 1.1 pre-operatively to 2.6 ± 0.8 post-operatively (P<0.05), and it improved further to 2.8 ± 1.1 in the final follow-up. The ODI score varied from 69.2 ± 1.2 pre-operatively to 32.2 ± 1.1 post-operatively (P<0.05). Improvement was maintained in the final follow-up. Comparing the height of anterior vertebrae (Ha), the height of midline vertebrae (Hm) and the kyphotic angle between pre-and post-operation there was no statistical significant difference. Conclusion: Kyphoplasty via unilateral extrapedicular approach for the treatment of osteoporotic thoracic compression fractures is effective. It can help reducing the radiation exposure. (authors)

They had no active shoulder abduction, external rotation, and elbow flexion. The pectoralis major and minor were cut and/or retracted to expose the underlying infraclavicular plexus. The axillary nerve was identified with respect to the available donor nerves (long head of triceps branch, thoracodorsal nerve, and medial pectoral nerve). In addition to the axillary nerve neurotisation, each patient had a spinal accessory nerve transferred to the suprascapular nerve for better shoulder animation. Patients were followed up for 24 to 30 (mean, 26) months. In the 3 patients with C5-T1 nerve root injuries, the mean active abduction and external rotation were 63 and 20 degrees, respectively, whereas the mean abduction strength was M3 (motion against gravity). In the 6 patients with C5-C6 nerve root injuries, the mean active abduction and external rotation were 133 and 65 degrees, respectively, whereas the strength of the deltoids and triceps was M5 (normal) in all. In 4 patients with the pectoralis major cut and repaired, the muscle regained normal strength. The anterior deltopectoral approach enabled easy access to all available donor nerves for axillary nerve neurotisation and achieved good outcomes.

    Full Text Available Cyproterone has antiandrogenic, antigonadotropic, and progestagenic activity. High-dose preparations are used for treatment of prostate cancer and for treatment of hypersexuality. We describe a patient who was referred to our clinic with slowly progressive unilateral proptosis and blindness of the left eye. He had been treated with high-dose cyproterone actate (CPA for 23 years. An obvious proptosis and exodeviation of his left eye was noted on ophthalmic examination. Fundoscopy showed left optic atrophy. The literature suggests a link between long-term high-dose exogenous progesterone agonist exposure and the progression and/or development of meningioma. MRI of the brain was performed and revealed multiple meningiomas. One large meningioma located in the anterior temporal lobe extended into the left orbit and caused the proptosis and blindness. Treatment with CPA was stopped and follow-up imaging 11 months later showed a significant decrease in size of the largest meningiomas.

    Full Text Available X-linked juvenile retinoschisis is a rare hereditary retinal disease characterized by a tangential splitting of the neurosensory retina which may cause early-onset visual impairment. Existence of the retinal neurosensory layer splitting on cross-sectional images of optical coherance tomography (OCT and the absence of leakage on fluorescein angiography (FA help confirming the diagnosis. Such diagnostic tests are also helpful in determining the management of the disease. However, most of the retinoschisis cavities remain stable and rarely extend to the posterior pole, many authors suggest laser prophylaxis to avoid the potential risk of retinal detachment due to holes in the outer retinal layer. Herein, we report a case with bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis who was evaluated with detailed ophthalmologic examination. Visual acuity, fundoscopy, OCT, and FA remained stable in the second year of follow-up after prophylactic argon laser treatment.

  17. The unilateral appointment of co-arbitrators

    DEFF Research Database (Denmark)

    2016-01-01

    Contractual practices and the applicable law on the composition of three-member tribunals normally provide for each party to select a co-arbitrator unilaterally. This procedure may make the co-arbitrators appear partial and may lead to improper dissenting opinions and premature resignations, which...... may ultimately threaten the confidence in arbitration and arbitral awards, but the procedure does not remain common for nothing. The arbitration community therefore needs to reconsider the appointment procedure on a solid and deliberate basis, and such a basis is what the article provides. A number...... of experienced arbitration practitioners have advocated against the procedure for some of the reasons above, whereas other experienced arbitration practitioners have defended the procedure because of its practical advantages and underlying rationales. Each of the previous contributions to the debate sheds light...

    2013-09-01

    Migraine attacks exclusively felt in the face are very rare, the pain involving the territories supplied by the second and third branches of the trigeminal nerve. Two patients suffering from heminasal pain attacks accompanied with typical migrainous features and responsive to oral or intranasal triptans - but not to intranasal lidocaine or oxymetazoline. In one patient, the attacks could be precipitated upon slight touching on the tip of the nose, in the other attacks were preceded by the nasal sensation typically heralding sneezing. Migraine pain mostly develops within the innervation territory of the first branch of the trigeminal nerve, which includes the nose. Therefore, episodes of unilateral nasal pain with migrainous features could be considered a migraine with unusual topography (nasal migraine). Painful nasal attacks occasionally preceded by stimulation of trigeminal afferents in the nose, could be conceived of as migraine-tic syndrome.

    To evaluate the cost-effectiveness of obtaining a magnetic resonance imaging (MRI) in patients with abnormal electronystagmography (ENG) or videonystagmography (VNG) results. Retrospective chart review. Academic specialty center. Patients presenting with vertigo between January 1, 2010, and August 30, 2013. Patients who fit the following abnormal criteria were included in the study: unilateral caloric weakness (≥20%), abnormal ocular motor testing, and nystagmus on positional testing. Patients with abnormal findings who then underwent MRI with gadolinium were evaluated. Of the 1,996 charts reviewed, there were 1,358 patients who met the inclusion criteria. The average age of these patients was 62 years (12-94 yr). The male:female ratio was approximately 1:2. Of the 1,358 patients, 253 received an MRI with the following pathologies: four vestibular schwannomas, three subcortical/periventricular white matter changes suspicious for demyelinating disease, four acute cerebellar/posterior circulation infarct, two vertebral artery narrowing, one pseudomeningocele of internal auditory canal, and two white matter changes indicative of migraines. The positive detection rate on MRI was 5.5% based on MRI findings of treatable pathologies causing vertigo. Average cost of an MRI is $1,200, thereby making the average cost of identifying a patient with a positive MRI finding $15,180. In our study, those patients with a positive MRI had a constellation of symptoms and findings (asymmetric sensorineural hearing loss, tinnitus, vertigo, and abnormal ENG/VNG). Cost-effectiveness can be improved by ordering an MRI only when clinical examination and VNG point toward a central pathology. Clinical examination and appropriate testing should be factored when considering the cost-effectiveness of obtaining an MRI in patients with abnormal ENG/VNG findings.

    Little is known about the vestibulo-perceptual (VP) system, particularly after a unilateral vestibular lesion. We investigated vestibulo-ocular (VO) and VP function in 25 patients with vestibular neuritis (VN) acutely (2 days after onset) and after compensation (recovery phase, 10 weeks). Since the effect of VN on reflex and perceptual function may differ at threshold and supra-threshold acceleration levels, we used two stimulus intensities, acceleration steps of 0.5°/s2 and velocity steps of 90°/s (acceleration 180°/s2). We hypothesised that the vestibular lesion or the compensatory processes could dissociate VO and VP function, particularly if the acute vertiginous sensation interferes with the perceptual tasks. Both in acute and recovery phases, VO and VP thresholds increased, particularly during ipsilesional rotations. In signal detection theory this indicates that signals from the healthy and affected side are still fused, but result in asymmetric thresholds due to a lesion-induced bias. The normal pattern whereby VP thresholds are higher than VO thresholds was preserved, indicating that any ‘perceptual noise’ added by the vertigo does not disrupt the cognitive decision-making processes inherent to the perceptual task. Overall, the parallel findings in VO and VP thresholds imply little or no additional cortical processing and suggest that vestibular thresholds essentially reflect the sensitivity of the fused peripheral receptors. In contrast, a significant VO-VP dissociation for supra-threshold stimuli was found. Acutely, time constants and duration of the VO and VP responses were reduced – asymmetrically for VO, as expected, but surprisingly symmetrical for perception. At recovery, VP responses normalised but VO responses remained shortened and asymmetric. Thus, unlike threshold data, supra-threshold responses show considerable VO-VP dissociation indicative of additional, higher-order processing of vestibular signals. We provide evidence of

    Currently there is no consensus regarding the use of bilateral simultaneous percutaneous surgery for Hallux valgus treatment. Although the technique described in M. Prado's book, recommends operating only one foot at a time there are no published studies confirming it. The aim of this study was to evaluate whether there is a difference between the results of patients that have been percutaneously operated on one foot and those operated on both feet at the same surgical time for mild to moderate Hallux valgus correction. We did a retrospective single centre evaluation of 93 feet (61 patients) with Hallux valgus operated percutaneously. 29 patients were operated unilaterally (group I) and 32 bilaterally simultaneously (group II) between 2005 and 2009. The Metatarsophalangeal angle (MPA), Intermetatarsal angle (IMA) and Distal metatarsal articular angle (DMAA) were evaluated pre- and postoperatively. The AOFAS score, the degree of patients' satisfaction and the complications were evaluated postoperatively. The mean follow-up was 24.0 months in group I, and 28.0 in group II. The average postoperative AOFAS score was 86.8, 82.9 in group I and 88.6 in group II (p>0.05). 90.6% were satisfied or very satisfied in group I, and 89.7% in group II (p>0.05). There was no statistically significant difference (p>0.05) in the average correction of MPA, DMAA, and IMA. The complications rate was similar in both groups. The similar results obtained in both groups suggest that the simultaneous bilateral percutaneous surgery gives equivalent results to the unilateral, which has an important socioeconomic impact since there is only one recovery time for both feet.

    To describe and compare the plantar pressures, temporal foot roll-over, and ground reaction forces (GRFs) between both limbs of subjects with unilateral transfemoral amputation and with those of able-bodied participants during walking. We also verify the relevance of a force plate and a pressure plate to discriminate changes in gait parameters of subjects with limb loss. Cross-sectional study. Biomechanics laboratory. A total of 14 subjects with unilateral transfemoral amputation and 21 able-bodied participants. We used a force plate and a pressure plate to assess biomechanical gait parameters while the participants were walking at their self-selected gait speed. We measured plantar pressure peaks in 6 foot regions and the instant of their occurrence (temporal foot roll-over); and GRF peaks and impulses of anterior-posterior (braking and propulsive phases), medial-lateral, and vertical (load acceptance and thrust phases) components. The thrust, braking, and propulsive peaks, and the braking and propulsive impulses, were statistically significantly lower in the amputated limb than in the sound limb (P guide the rehabilitation of subjects with lower limb amputation.

    2002-01-01

    Purpose: To describe CT appearances in patients with unilateral cleft lip and palate (CLP) 20 years after bone graft surgery. Material and Methods: Eighteen consecutive patients with unilateral CLP were examined. All patients had been treated with primary closure, both in infancy and early childhood, supplemented with bone grafting at the age of around 10 years. The CT examination of the upper jaw included a dental CT program. The CT appearances of the cleft side were compared with those of the untreated non-cleft side. Results: Abnormal CT appearances included skew nasal aperture (n=17), nasal septal deviation (n=17), low floor of nasal aperture (n=15) at or towards the cleft side, and deviation of anterior nasal spine towards the non-cleft side (n=18). The posterior part of the bone cleft was visible in all patients, and the dental arch was V-shaped in 8. Conclusion: Although adherence to the present treatment protocol is considered to give satisfactory functional and cosmetic results, certain abnormalities persist. A knowledge of these is a prerequisite for a complete and final evaluation of the surgical and orthodontic regimen. Cleft palate nasal cavity abnormalities CT

    Rehabilitation of patients with unilateral cleft lip and palate (UCLP) requires multiple steps and coordination of multidisciplinary sciences to produce optimal results. Alveolar bone-grafting (ABG) is an important procedure in the treatment of such patients because it influences the eruption of teeth and stabilizes the maxilla. To evaluate the effect and suitability of alveolar bone grafting procedure at Cleft Center Harapan Kita Maternal and Child Hospital on nasal deformity from anthropometry with photogrammetry and aesthetic proportional in patients with unilateral cleft lip and palate with UCLP. Patients with UCLP were evaluated post-ABG using anthropometry and photogrammetry to investigate the results anteriorly, laterally, and basally. Anthropometric measurements taken photogrammetrically used 14 points and 11 distance items. Evaluations were made of upper lip length, upper lip projection, and nostril sill elevation for both the cleft and non-cleft sides of patients’ faces. A t-test showed that the values for upper lip length and projection were significantly increased, and a correction test using a Fisher exam gave a value of 1. The ABG treatment protocol for patients with UCLP at the Cleft Lip and Palate Unit at Harapan Kita Maternal and Child Hospital is suitable to be performed; it aesthetically satisfies patients and their families.

    Monaural auditory input due to congenital or acquired unilateral hearing loss (UHL) may have neurobiological effects on the developing brain. Using functional magnetic resonance imaging (fMRI), we investigated the effect of UHL on the development of functional brain networks used for cross-modal processing. Children ages 7-12 with moderate or greater unilateral hearing loss of sensorineural origin (UHL-SN; N = 21) and normal-hearing controls (N = 23) performed an fMRI-compatible adaptation of the Token Test involving listening to a sentence such as "touched the small green circle and the large blue square" and simultaneously viewing an arrow touching colored shapes on a video. Children with right or severe-to-profound UHL-SN displayed smaller activation in a region encompassing the right inferior temporal, middle temporal, and middle occipital gyrus (BA 19/37/39), evidencing differences due to monaural hearing in cross-modal modulation of the visual processing pathway. Children with UHL-SN displayed increased activation in the left posterior superior temporal gyrus, likely the result either of more effortful low-level processing of auditory stimuli or differences in cross-modal modulation of the auditory processing pathway. Additionally, children with UHL-SN displayed reduced deactivation of anterior and posterior regions of the default mode network. Results suggest that monaural hearing affects the development of brain networks related to cross-modal sensory processing and the regulation of the default network during processing of spoken language.

    Full Text Available Abstract Introduction Cervical necrotizing fasciitis is an aggressive infection with high morbidity and mortality. We present a case of cervical necrotizing fasciitis and descending mediastinitis in a healthy young man, caused by unilateral tonsillitis with a successful outcome without aggressive debridement. Case presentation A 41-year-old man was admitted to our unit with a diagnosis of severe acute unilateral tonsillitis. On admission, he had painful neck movements and the skin over his neck was red, hot and tender. Computed tomography scan of his neck and chest showed evidence of cervical necrotizing fasciitis and descending mediastinitis secondary to underlying pharyngeal disease. He was treated with broad-spectrum intravenous antibiotics. His condition improved over the next 3 days but a tender and fluctuant swelling appeared in the suprasternal region. A repeat scan showed the appearance of an abscess extending from the pretracheal region to the upper mediastinum which was drained through a small transverse anterior neck incision. After surgery, the patient's condition quickly improved and he was discharged on the 18th day of admission. Conclusion Less invasive surgical techniques may replace conventional aggressive debridement as the treatment of choice for cervical necrotizing fasciitis and descending necrotizing mediastinitis.

    Full Text Available Isolated Unilateral Absent Pulmonary Artery (UAPA is a rare congenital anomaly. It is usually associated with congenital heart defects. A 45 year old male patient presented with complaints of fever with cough and expectoration for 15 days and retrosternal chest discomfort for the previous 2 days. ECG showed diffuse ST segment depression with T wave inversion in the inferior and lateral leads. Coronary Angiogram done through the right femoral approach revealed diffusely diseased Left Anterior Descending (LAD artery that was totally cut off at the mid segment. The Left Circumflex (LCx artery was providing blood supply to the right middle and lower lung areas. There was another collateral arising from the Left Subclavian Artery supplying the right middle and lower lung areas. The left pulmonary artery was normal, but branches supplying the middle and lower lobes of the right lung were absent and the upper lobe branch had pulmonary stenosis. UAPA is a rare clinical entity; collaterals from coronaries are extremely rare in this condition and till now there has not been any case report of unilateral absent branch pulmonary artery with peripheral stenosis of other branches, on the affected side and associated coronary artery disease.

  11. Altered regional and circuit resting-state activity associated with unilateral hearing loss.

    Xingchao Wang

    Full Text Available The deprivation of sensory input after hearing damage results in functional reorganization of the brain including cross-modal plasticity in the sensory cortex and changes in cognitive processing. However, it remains unclear whether partial deprivation from unilateral auditory loss (UHL would similarly affect the neural circuitry of cognitive processes in addition to the functional organization of sensory cortex. Here, we used resting-state functional magnetic resonance imaging to investigate intrinsic activity in 34 participants with UHL from acoustic neuroma in comparison with 22 matched normal controls. In sensory regions, we found decreased regional homogeneity (ReHo in the bilateral calcarine cortices in UHL. However, there was an increase of ReHo in the right anterior insular cortex (rAI, the key node of cognitive control network (CCN and multimodal sensory integration, as well as in the left parahippocampal cortex (lPHC, a key node in the default mode network (DMN. Moreover, seed-based resting-state functional connectivity analysis showed an enhanced relationship between rAI and several key regions of the DMN. Meanwhile, lPHC showed more negative relationship with components in the CCN and greater positive relationship in the DMN. Such reorganizations of functional connectivity within the DMN and between the DMN and CCN were confirmed by a graph theory analysis. These results suggest that unilateral sensory input damage not only alters the activity of the sensory areas but also reshapes the regional and circuit functional organization of the cognitive control network.

    Full Text Available The principal symptoms of unilateral vocal fold paralysis are hoarseness and difficulty in swallowing. Dyspnea is comparatively rare (Laccourreye et al., 2003. The extent to which unilateral vocal fold paralysis may lead to respiratory problems at all - in contrast to bilateral vocal fold paralysis- has not yet well been determined. On the one hand, inspiration is impaired with unilateral vocal fold paralysis; on the other hand, neither the position of the vocal fold paralysis nor the degree of breathiness correlates with respiratory parameters (Cantarella et al., 2003; 2005. The question of what respiratory stress a patient with a vocal fold paresis can endure has not yet been dealt with.A 43 year-old female patient was suffering from recurrent unspecific respiratory complaints for four months after physical activity. During training for a marathon, she experienced no difficulty in breathing. These unspecific respiratory complaints occurred only after athletic activity and persisted for hours. The patient observed neither an increased coughing nor a stridor. Her voice remained unaltered during the attacks, nor were there any signs of a symptomatic gastroesophageal reflux or infectious disease. A cardio-pulmonary and a radiological examination by means of an X-ray of the thorax also revealed no pathological phenomena. As antiallergic and antiobstructive therapy remained unsuccessful, a laryngological examination was performed in order to exclude a vocal cord dysfunction.Surprisingly enough, the laryngostroboscopy showed, as an initial description, a vocal fold paralysis of the left vocal fold in median position (Figure 1. The anamnestic background for the cause was unclear. The only clue was a thoracotomy on the left side due to a pleuritis in childhood. A subsequent laryngoscopic examination had never been performed. Good mucosa waves and amplitudes were shown bilateral with complete glottal closure. Neither in the acoustic analysis, nor in the

    Pseudoexfoliation syndrome (PEX) is the most frequently identifiable cause of secondary open-angle glaucoma, known as pseudoexfoliation glaucoma. The exact pathophysiology and etiology of PEX and associated glaucoma remains obscure. The purpose of this study was to determine the differences in the morphology of the anterior chamber angle in people with pseudoexfoliation syndrome and pseudoexfoliation glaucoma compared to a control group. We also evaluated the correlation between intraocular pressure (IOP) and pigmentation of the angle with the amount of exfoliated material in the anterior segment. The study group was composed of 155 eyes from 103 patients aged between 43 and 86 years. Each patient underwent a complete ophthalmological examination. Some difference was found in intraocular pressure between the PEX group and the control group and between the pseudoexfoliation glaucoma group and the control group, but no significant difference was found between the 2 study groups. There was a significant difference in the incidence of some degree of pigmentation in the anterior chamber angle and no difference in the widths of the angle between each group. A significant positive relationship was observed between intraocular pressure and the degree of pigmentation of the anterior chamber angle in both the PEX group and the pseudoexfoliation glaucoma group. The results of this study indicate that the amount of pigmentation and exfoliation material in the anterior segment significantly correlates with the level of IOP and possibly with the degree of trabecular dysfunction. It seems that for clear identification of PEX and pseudoexfoliation glaucoma factors, clinical assessment appears to be insufficient.

    Ankle arthrodesis is a common procedure that resolves many conditions of the foot and ankle; however, complications following this procedure are often reported and vary depending on the fixation technique. Various techniques have been described in the attempt to achieve ankle arthrodesis and there is much debate as to the efficiency of each one. This study aims to evaluate the efficiency of anterior plating in ankle arthrodesis using customised and Synthes TomoFix plates. We present the outcomes of 28 ankle arthrodeses between 2005 and 2012, specifically examining rate of union, patient-reported outcomes scores, and complications. All 28 patients achieved radiographic union at an average of 36 wk; the majority of patients (92.86%) at or before 16 wk, the exceptions being two patients with Charcot joints who were noted to have bony union at a three year review. Patient-reported outcomes scores significantly increased (P plate offers added compression and provides a rigid fixation for arthrodesis stabilization. PMID:24649408

    Full Text Available Background/Aim. All changes in the knee that appear after anterior cruciate ligament (ACL lesion lead to difficulties in walking, running, jumping especially during sudden changes of the line of movement. This significantly impairs quality of life of these subjects and leads to decrease in physical activity. Knee injuries make 5% of all most severe acute sport injuries. The aim of the study was to determine strength of the thigh muscles in persons with unilateral rupture of the ACL and to evaluate potential bilateral differences between healthy and injured leg. Methods. This study involved 114 male athletes of different sport specialities with the clinical diagnosis of ACL rupture. Each subject had unilateral ACL rupture and the other leg was actually the control for this research. An isokinetic device was used to evaluate the muscle strength of thigh muscles. Testing was performed for two testing speeds, 60º/s and 180º/s. Results. Data analysis showed a statistically significant difference (p < 0.01 between the ACL and the healthy leg in the following parameters: peak torque for thigh extensors (Ptrq_E, angle to peak torque during extension (Ang_E, power of extension (Pow_E and work during extension (Work_E. Analysing hamstrings to quadriceps (H/Q ratio we found the unilateral disbalance of thigh muscle strength in ACL leg. Conclusion. A high level of validity makes isokinetic dynamometry the method for evaluation of thigh muscles strength and leaves this field of research open for new studies in order to improve both diagnostic and rehabilitation of patients with the insufficient ACL.

    To compare the change in anterior segment morphology after laser peripheral iridotomy (LPI) in acute primary angle closure (APAC) and their fellow eyes. Prospective, fellow eye-matched case series. In this study 42 individuals with unilateral episode of APAC were enrolled and the anterior segment optical coherence tomography (ASOCT) images were obtained in both eyes at baseline and at 6 weeks after LPI. A linear mixed-effects model was used to compare changes in anterior chamber and angle variables with consideration of laterality as the random effect and pupil diameter as the fixed effect. APAC eyes had smaller angle parameters (P = .013 for all), less central anterior chamber depth (cACD) (P APAC and fellow eyes. cACD (P = .003) and ACA (P APAC eyes. However, there was no significant change in cACD (P = .190) and LV (P = .430) in fellow eyes. In both APAC eyes and fellow eyes, iris curvature decreased after LPI (P APAC eyes and their fellow eyes, LPI resulted in significant anterior chamber angle widening and increased anterior chamber area. In APAC eyes, the iris flattened, cACD deepened, and the lens shifted posteriorly after resolution of the attack. However, in fellow eyes, the increase in ACA was mainly owing to decreased iris curvature. Copyright © 2017 Elsevier Inc. All rights reserved.

    This study aimed at evaluating the voiding patterns of adult patients who underwent hypospadias repair in childhood. Following IRB approval 103 (22.7%) of 449 adult patients who underwent hypospadias repair between 1978 and 1993 responded to the following questionnaires: International Prostate Symptom Score (I-PSS) and Short Form 12 questionnaire (SF-12). Uroflowmetry (UF) was performed for all patients. The patients were divided into three groups according to the primary meatus localization. Group I had 63 patients (61.5%) treated for glanular hypospadias, group II had 19 patients (18.4%) treated for distal hypospadias, and group III comprised the remaining 21 patients (20.4%) treated for proximal hypospadias. The mean ± SD I-PSS score for all patients who responded to the questionnaire was 2.3 ± 2.4, and UF was 21.1 ± 4.3 mL/s. The patients from groups I and III had fewer urinary symptoms compared with those of the group II: 1.3 ± 1.5, 5.5 ± 2.4, and 1.6 ± 1.4, respectively (p hypospadias repair in childhood had normal or mild voiding disturbance, with no effects on their physical or mental status.

    We investigated into association of quality of life(QOL)and prognosis of breast cancer patients who underwent neoadjuvant chemotherapy(NAC). We retrospectively studied 228 patients with breast cancer who were performed NAC during a period between 2007 and 2015. TheQ OL score was measured with"The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs(QOL-ACD)". We evaluate association between QOL score with antitumor effect and prognosis. Changes in the QOL score between before and after NAC were compared as well. We divided 2 groups by QOL-ACD scoreinto high and low groups. Therapeautic effect of NAC on 75 patients were pathological complete response(pCR). QOL-ACD score was not significantly associated with pCR rate in both high and low groups(p=0.199). High group was significantly associated with higher survival rate in both of disease free survival(p=0.009, logrank)and overall survival(p=0.040, logrank). QOLACD score decreased after NAC in both of pCR and non-pCR patients. In conclusion, QOL evaluation using QOL-ACD could be an indicator of breast cancer patients' prognosis who underwent NAC.

    The role of HLA-G in several clinical conditions related to reproduction has been investigated. Important polymorphisms have been found within the 5'URR and 3'UTR regions of the HLA-G promoter. The aim of the present study was to investigate 16 SNPs in the 5'URR and 14-bp insertion/deletion (ins/del) polymorphism located in the 3'UTR region of the HLA-G gene and its possible association with the implantation outcome in couples who underwent assisted reproduction treatments (ART). The case group was composed of 25 ART couples. Ninety-four couples with two or more term pregnancies composed the control group. Polymorphism haplotype frequencies of the HLA-G were determined for both groups. The Haplotype 5, Haplotype 8 and Haplotype 11 were absolute absence in ART couples. The HLA-G*01:01:02a, HLA-G*01:01:02b alleles and the 14-bp ins polymorphism, Haplotype 2, showed an increased frequency in case women and similar distribution between case and control men. However, this susceptibility haplotype is significantly presented in case women and in couple with failure implantation after treatment, which led us to suggest a maternal effect, associated with this haplotype, once their presence in women is related to a higher number of couples who underwent ART.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Full Text Available Objective: To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy. Methods: A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0, 30 min during operation (T1, and 12 h after operation (T2 were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05. HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05. PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05. Conclusions: Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

    To study the effect of the internal fixation lamp on anterior chamber width measured by anterior segment optical coherence tomography. In a prospective cross sectional observational study, consecutive 22 right eyes of 22 patients (4 men and 18 women) with suspected primary angle closure underwent swept source domain anterior segment optical coherence tomography (AS-OCT), (CASIA SS-1000, Tomey, Nagoya, Japan). Anterior chamber parameters of angle opening distance (AOD), trabecular-iris angle (TIA), angle recess area (ARA) at 500 or 750 µm from scleral spur and pupil diameter were measured by AS-OCT in a three-dimensional mode in 4 quadrants (superior, inferior, temporal and nasal) in dark room setting both with and without internal fixation lamp. Anterior segment parameters of AOD 500 in superior, inferior and temporal quadrants, AOD 750 at superior and nasal, TIA 500 at superior, and inferior and TIA 750 at superior and nasal, and ARA 500 or 750 at superior and inferior with internal fixation lamp were greater and the pupil diameter was significantly (all P chamber angle is narrow but open, it is recommended that the internal fixation lamp be turned off to ensure a clear indication as to whether the angle is open or closed in the dark.

    To examine the long-term neuropsychological outcome of children with a prenatal diagnosis of asymmetric ventricles or unilateral ventriculomegaly. A clinic-based neuropsychological study. Paediatric neurology clinic. Thirty-three of 41 children, previously assessed at kindergarten age, with asymmetric ventricles or unilateral ventriculomegaly identified in utero, were recruited at school age for a neuropsychological follow-up. All children, 9-11 years of age, underwent a battery of neuropsychological tests and the parents completed behavioural rating questionnaires. Results of the neuropsychological assessment and parents' questionnaires. There were no significant differences between children diagnosed with either asymmetric ventricles or unilateral ventriculomegaly in most parameters relative to the general population; the full-scale IQ scores were 103.13 ± 12.43 and 103.56 ± 10.5, respectively. A significantly lower performance was found only on one measure of attention among the unilateral ventriculomegaly group and on writing speed tasks among the asymmetric ventricles group. Both study groups showed significantly higher scores than expected in the normal population on a verbal fluency test. Comparison of both groups combined with the normative population yielded significantly lower scores only in attention tests. Yet, the clinical population showed significantly higher scores on writing accuracy, processing speed and verbal fluency and lower rates of executive dysfunction. Asymmetric ventricles or unilateral ventriculomegaly identified in utero does not appear to affect long-term mental development and school achievements. Further prospective research on a larger sample is needed in order to confirm our findings. © 2014 Royal College of Obstetricians and Gynaecologists.

    This study examined the influence of immobilization on chondrocyte apoptosis and histological features of the anterior cruciate ligament (ACL) insertion and knee articular cartilage in rabbits. Forty-eight male Japanese white rabbits were assigned to an immobilization ( n = 24) or sham ( n = 24) group. Rabbits in the immobilization group underwent complete unilateral surgical knee immobilization and rabbits in the sham group underwent a sham surgery. The average thickness of the glycosaminoglycan (GAG) stained red area by safranin O staining, the chondrocyte apoptosis rate and the chondrocyte proliferation rate in the cartilage layer in the ACL insertion and the articular cartilage of the medial tibial condyle were measured at one, two, four and eight weeks in six animals from each group. In the ACL insertion, the chondrocyte apoptosis rate was higher in the immobilization group than in the sham group at two and eight weeks after surgery ( p immobilization group. The GAG layer was thinner in the immobilization group than in the sham group at two, four and eight weeks after surgery ( p immobilization group was higher than in the sham group at four and eight weeks after surgery ( p immobilization group than that in the sham group at four and eight weeks after surgery ( p immobilization significantly increased chondrocyte apoptosis at two and eight weeks after surgery in the ACL insertion and at four and eight weeks after surgery in the articular cartilage of the medial tibial condyle, and decreased GAG layer thickness from two to eight weeks after surgery in the ACL insertion and from four to eight weeks after surgery in the articular cartilage.

    Cleft lip and palate patients commonly present maxillary constriction, particularly in the anterior region. The aim of this case report was to describe an alternative clinical approach that used a smaller Hyrax screw unconventionally positioned to achieve greater anterior than posterior expansion in patients with complete unilateral cleft lip and palate. The idea presented here is to take advantage of a reduced dimension screw to position it anteriorly. When only anterior expansion was needed (patient 1), the appliance was soldered to the first premolar bands and associated to a transpalatal arch cemented to the first molars. However, when overall expansion was required (patient 2), the screw was positioned anteriorly, but soldered to the first molar bands. Intercanine, premolar, and first molar widths were measured on dental casts with a digital caliper. Pre-expansion and postexpansion radiographs and tomographies were also evaluated. A significant anterior expansion and no intermolar width increase were registered in the first patient. Although patient 2 also presented a greater anterior than posterior expansion, a noteworthy expansion occurred at the molar region. The alternative approach to expand the maxilla in cleft patients reported here caused greater anterior than posterior expansion when the Mini-Hyrax was associated to a transpalatal arch, and its reduced dimension also minimized discomfort and facilitated hygiene.

    To evaluate the pattern of anterior segment indocyanine green (ICG) angiography in episcleritis and scleritis. Prospective comparative (paired-eye) observational case series. Twenty subjects presenting clinical diseases compatible with episcleritis or scleritis. Anterior segment ICG angiography was performed according to a standard protocol in subjects presenting either episcleritis or scleritis. Photographs of the anterior segment were taken in the early phase (up to 3 minutes after dye injection), intermediate phase (10-12 minutes) and late phase (30-45 minutes). The inflamed zones were compared with the same regions of the controlateral eye. The amount of protein ICG exudation was scored by a masked observer as follows: zero for no exudation, one for slight exudation, two for moderate exudation, and three for severe exudation. Evaluation of dye leakage, which reflects protein exudation, with anterior segment ICG angiography in episcleritis and scleritis. Twenty subjects with a mean age of 43 +/- 15 years (7 male, 13 female) were enrolled in the study. Thirteen subjects had anterior scleritis (7 nodular, 5 diffuse, and 1 scleromalacia perforans), and 7 subjects had episcleritis. Only 1 out of 7 subjects with episcleritis showed a slight ICG leakage (a score of one), whereas all subjects with scleritis had ICG leakage scores of one or more (P = 0.0005, Fisher exact test). ICG angiography of the anterior segment of the eye is a good clinical test to differentiate episcleritis from scleritis.

    Full Text Available Objectives: To report the intraoperative and postoperative follow-up complications and management of these in deep anterior lamellar keratoplasty (DALK surgery. Materials and Methods: Two hundred eighty-four eyes of 252 patients followed up in our cornea clinic who underwent DALK using Anwar’s big-bubble technique with healthy Descemet’s membrane and endothelium were included in this study. Intraoperative and postoperative complications as well as the management and treatment of these complications were evaluated. Results: Big bubble was created in 220 (77.5% eyes of 284 eyes, and lamellar dissection was performed in 64 (22.5% eyes. Perforation occurred during trephination in 4 eyes, and the procedure was accomplished by penetrating keratoplasty (PK. Intraoperative microperforation occurred in 44 eyes. Perforation enlarged in 4 eyes and PK was performed. Operation was continued in 40 eyes with air injection into the anterior chamber. In postopertive follow-up period, double anterior chamber (DAC occurred in 32 of 40 eyes. DAC spontaneously regressed in 8 eyes, and air was given into the anterior chamber with a second surgical intervention in 24 eyes. DAC improved in 20 eyes. Four eyes underwent PK. Fungal keratitis evolved at the interface in one eye, because of no healing during the follow-up period, this eye underwent PK under antifungal therapy. Eyes with interface haze and Descemet’s membrane folds were followed. Conclusion: DALK is a difficult technique with a steep learning curve. In addition to the complications seen in PK, specific complications can occur in lamellar surgery. (Turk J Ophthalmol 2014; 44: 337-40

    Purpose: To compare the impact of an unilateral post-operative irradiation or a bilateral irradiation in terms of loco-regional control and survival in patients with cervical lymph node of squamous cell carcinoma from an unknown primary (CUP). Methods and materials: Ninety five patients with epidermoid carcinoma involving unilateral cervical lymph nodes from an unknown primary were treated in two institutions from 1990 to 2007. Post-operative radiation therapy was delivered to one side of the neck in 59 cases, to both sides of the neck in 36 cases. There were 11 women and 84 men ranging in age from 38 to 80 years (median 59 years). Neck dissection was performed in 79 patients while 16 patients underwent single lymph node sampling only. Results: After a median follow-up of 3.3 years, the nodal relapse rate was 34% after unilateral neck irradiation and 25% after bilateral radiotherapy (p = 0.21). Six contralateral lymph node relapses occurred after unilateral irradiation (10%). The 5-year overall survival rate of the entire group was 24%. The 5-year OS rates were 22% after unilateral irradiation and 23%, after bilateral radiotherapy (p = 0.944). The occult primary occurred in 12% after unilateral irradiation and 6% after bilateral radiotherapy. The radiation technique (3D-CRT or IMRT vs. 2D: p = 0.026) was prognostic on loco-regional control. Independent prognostic determinants on overall survival were the WHO status (p = 0.013) and the radiation technique (2D vs. 3D-CRT or IMRT; p = 0.029). There was no difference in loco-regional control (p = 0.639) and no difference in survival (p = 0.493) when chemotherapy was associated. Conclusions: Retrospective comparisons between bilateral and unilateral neck radiotherapies did not show differences in terms of loco-regional control and survival. However, patient's local regional control and survival are significantly improved after 3D-CRT or IMRT.

    Robotic technology may be a promising tool in reduction of morbidity in radical anterior pelvic exenteration for invasive bladder cancer. We report our initial experience with robotic-assisted radical anterior pelvic exenteration in females in an attempt to evaluate the technique's feasibility and outcomes. A retrospective review of our bladder cancer database was performed. Twelve women that underwent robotic-assisted radical anterior pelvic exenteration, bilateral pelvic lymphadenectomy, and urinary diversion for clinically localized urothelial carcinoma of the bladder between 2004 and 2008 were included in this retrospective study. Median age was 73.0 +/- 9.6 years and median body mass index (BMI) was 23.5 +/- 5.0 kg/m2. Ten patients underwent ileal conduit diversion, one had an orthotopic neobladder and one an Indiana pouch. Median total operating time was 6.4 +/- 1.5 hours with median console and diversion times of 4.7 +/- 0.9 and 2.5 +/- 1.5 hours respectively. Median blood loss was 275.0 +/- 165.8 ml. Median length of stay was 8.0 +/- 1.6 days. Four patients were T2N0 or less, five T3N0, one T3N1 and two patients T4N0. There was one patient with positive surgical margins. Median number of lymph nodes removed was 23.0 +/- 11.4. Median follow-up of 9.0 +/- 6.0 months was available for ten patients. One had a recurrent ureteroenteric stricture, one had colpocleisis for vault prolapse, and three had metastatic disease. Robotic-assisted laparoscopic anterior pelvic exenteration appears to be a favorable surgical option with acceptable operative, pathological, and short-term clinical outcomes. According to the UCI experience, robotic anterior exenteration appears to achieve the clinical and oncologic goals for the surgical treatment of bladder cancer.

    The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    Compare the visual acuity of patients who underwent cataract surgery by phacoemulsification with IOL AcrySof(®) toric implantation versus AcrySof(®) IQ and evaluate the reduction of cylindrical diopters (CD) in the postoperative period. Analytical and retrospective study of 149 eyes with 1 or more diopters of regular symmetrical keratometric astigmatism, which underwent cataract surgery by phacoemulsification. The eyes were divided into two groups: the toric group with 85 eyes and the non-toric group with 64 eyes. In the pre-operative phase, topographic data and refraction of each eye to be operated were assessed. In the postoperative phase, refraction and visual acuity with and without correction were measured. The preoperative topographic astigmatism ranged from 1.00 to 5.6 DC in both groups. Average reduction of 1.37 CD (p<0.001) and 0.16 CD (p=0.057) was obtained for the toric and non-toric group when compared to the refractive astigmatism, respectively. Considering visual acuity without correction (NCVA), the toric group presented 44 eyes (51.7%) with NCVA of 0 logMAR (20/20) or 0.1 logMAR (20/25) and the toric group presented 7 eyes (10.93%) with these same NCVA values. The results show that patients with a significant keratometric astigmatism presented visual benefits with the toric IOL implantation. The reduction of the use of optical aids may be obtained provided aberrations of the human eye are corrected more accurately. Currently, phacoemulsification surgery has been used not only for functional improvement, but also as a refraction procedure.

    To determine the effects of total parenteral nutrition (TPN) and enteral nutrition (EN) on biochemical and clinical outcomes in pancreatic cancer patients who underwent pancreaticoduodenectomy. From the year 2006 to 2008, 60 patients who underwent pancreaticoduodenectomy in Tianjin Third Central Hospital were enrolled in this study. They were randomly divided into the EN group and the TPN group. The biochemical and clinical parameters were recorded and analyzed between the two groups. There was no significant difference in the nutritional status, liver and kidney function, and blood glucose levels between the TPN and EN groups on the preoperative day, the 1st and 3 rd postoperative days. However, on the 7th postoperative day, there was significant difference between the two groups in 24 h urinary nitrogen, serum levels of, total protein (TP), transferrin (TF), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and γ-glutamyl transpeptadase (GGT), blood urea nitrogen (BUN) and creatinine (Cr). On the 14th postoperative day, there was a significant difference between the two groups in terms of urinary levels of 24 h nitrogen, TP, TF, retinol binding protein, ALT, AST, ALP, GGT, total bilirubin, direct bilirubin, BUN, Cr, and glucose. The incidence of delayed gastric emptying in the EN and TPN groups was 0% and 20%, respectively. Moreover, the incidence of pancreatic fistulas and hemorrhages in the EN group were 3.6% and 3.6%, versus 26.7% and 30% in the TPN group, respectively. EN is better than TPN for pancreatic cancer patients who received pancreaticoduodenectomy.

    To evaluate the effectiveness of percutaneous vertebroplasty (PVP) in the treatment of osteoporotic vertebral compression fractures with or without intravertebral clefts by unilateral approach and the impact of intravertebral clefts on the effectiveness. The clinical data of 65 patients who met the inclusion criteria of osteoporotic vertebral compression fracture were retrospectively analyzed. According to having intravertebral clefts or not, the patients were divided into 2 groups: cleft group (group A, n=25) and non-cleft group (group B, n=40). There was no significant difference in gender, age, cause of injury, the level of fracture vertebrae, degree of damage, and interval of injury and operation between 2 groups (P > 0.05). All patients were given PVP procedure by unilateral approach. The operation time, the injected volume of bone cement, time to ambulate, complications, and adjacent vertebral re-fracture were recorded. The height of anterior and middle column and the posterior convex Cobb angle of injured spine were measured on the lateral X-ray film in standing position at preoperation and 1, 48 weeks after operation. The visual analogue scale (VAS) score and Oswestry disability index (ODI) system were used to evaluate the pain relief and improvement of daily activity function respectively at preoperation and 1, 4, and 48 weeks after operation. There was no significant difference in the operation time and time to ambulate between 2 groups (P > 0.05). The injected volume of bone cement in group B was significantly less than that in group A (t=1.833, P=0.034). Asymptomatic cement leakage occurred in 6 patients (4 in group A and 2 in group B), in group A including 1 case of venous leakage, 2 cases of paravertebral leakage, and 1 case of intradiscal leakage; in group B including 2 cases of venous leakage. No symptomatic pulmonary embolism was observed. The vital sign was stable during operation and postoperatively. All patients were followed up 12-30 months

    To compare biometric differences between eyes with unilateral chronic primary angle-closure glaucoma (PACG) and fellow non-glaucomatous eyes in the same patient. Clinical data and imaging records of 17 patients with unilateral PACG were retrospectively reviewed. The fellow eyes with primary angle-closure (PAC) or primary angle-closure suspected (PACS) were grouped in Group 1. The PACG eyes were set as Group 2. The biometric parameters of both eyes were measured by IOL-Master, anterior segment optical coherence tomography (AS-OCT), and swept source OCT. The iris area in Group 1 was significantly thicker than that in Group 2 (1.590 ± 0.267 versus 1.365 ± 0.352, P = 0.016). Choroidal thickness in the macular region was thicker in Group 1 than in Group 2, with statistical significance at inner temporal grid (282.7 ± 121.1 versus 191.6 ± 90.3, P = 0.036), central field (297.4 ± 130.6 versus 200.1 ± 96.3, P = 0.029), inner nasal grid (283.1 ± 128.3 versus 194.8 ± 91.8, P = 0.040), and average value (265.3 ± 105.6 versus 191.1 ± 87.0, P = 0.049). Group 1 also had thicker peripapillary choroidal thickness at 1 o'clock (141.4 ± 68.4 versus 101.8 ± 39.0, P = 0.025) and 12 o'clock (141.5 ± 82.3 versus 104.5 ± 44.6, P = 0.037) compared to Group 2. The multivariate logistic regression analyses showed that only intraocular pressure was independently associated with PACG and explained 58.3% variance of PACG. In unilateral PACG, there was significant inter-eye difference in anterior and posterior segment parameters. Longitudinal comparisons are required to further understand the differences in pathology of angle closures.

    Congenital bilateral agenesis of the tibialis anterior muscles is a rare condition. We present a case of congenital absence of bilateral tibialis anterior muscles in a 6-year-old boy who presented with an abnormal gait. He was previously diagnosed to have bilateral congenital talipes equinovarus (CTEV) deformity for which he underwent corrective surgery two times. However, he still had a residual foot problem and claimed to have difficulty in walking. On examination, he walked with a high stepping gait and muscle power of both lower limbs was 5/5 on the medical research council scale (MRCS) except for both ankle dorsiflexors and long toe extensors. The sensation was intact. Magnetic Resonance Imaging (MRI) study of both legs revealed that tibialis anterior muscles were not visualized on both sides suggestive of agenesis of the tibialis anterior muscles. The rest of the muscles appeared mildly atrophied. The electrophysiological study showed normal motor and sensory conduction in both upper and lower limbs. Electromyographic (EMG) study of the vastus medialis was within normal limit and no response could be elicited for EMG of tibialis anterior muscles suggesting possible absence of tibialis anterior muscles, bilaterally. The patient underwent split tibialis posterior tendon transfer to achieve a balanced and functional foot and was well on discharge. The present case describes the normal anatomy and embryology of tibialis anterior muscles as well as possible causes of its agenesis along with its clinical implications.

    Objective. To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for knee arthroscopy.Design. An anterior approach to the knee joint was devised mimicking anterior portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidance a needle was advanced from a position adjacent to the patellar tendon into the knee joint. After confirmation of the needle tip location, a dilute gadolinium solution was injected.Results and conclusion. All the arthrograms were technically successful. The anterior approach to knee MRA has greater technical ease than the traditional approach with little patient discomfort. (orig.)

It can occasionally be seen on the corneal surface. We report our clinical and histopathological findings in a case of unilateral corneal leukoplakia. Methods: A 26-year-old woman was referred to our hospital because of a white patch on her right cornea that continued to expand. She first noticed the white patch when she was 20 years old, and the white patch had expanded to cover the pupillary area affecting her vision. After plastic surgery on both eyelids for bilateral entropion to alleviate the pain caused by the eyelashes rubbing the cornea, the white corneal patch decreased in size. Because of this reduction, we performed surgery to remove the patch with microforceps under topical anesthesia. The plaque was removed easily and completely, and submitted for histopathological examination. Results: Histopathological examination showed that the specimen had characteristics of epidermis with a basal cell layer, spinous cell layer, granular cell layer, and horny layer with hyperkeratosis. She was diagnosed with leukoplakia of the corneal surface. The basic structure of the squamous cell layer was preserved, and there were no signs of metaplasia. Six months after the removal of the leukoplakia, no recurrence was seen and her corrected decimal visual acuity recovered to 1

    To compare the extent of cage subsidence after anterior cervical discectomy and fusion (ACDF) using a cage alone or combined with anterior plate fixation, and to assess the effect of end plate removal on cage subsidence. Records of 23 men and 13 women aged 32 to 82 (mean, 54) years who underwent ACDF for 61 levels using the Solis cage alone (n=46) or combined with anterior plate fixation (n=15) were reviewed. The extent of cage subsidence was determined by comparing immediately postoperative (within one week) with final follow-up radiographs. Cage subsidence was defined as the sum subsidence of the superior and inferior part of the cage into the vertebral body. Mild and major cage subsidence was defined as ≤2 mm and >2 mm, respectively. Patients who underwent ACDF using a cage alone or combined with anterior plate fixation were comparable in terms of age, gender, follow-up duration, and number of levels decompressed. Cage subsidence occurred in 33 (54%) of the 61 levels decompressed. In the cage alone group, the extent of cage subsidence was greater (1.68 vs. 0.57 mm, p=0.039) and the rate of major cage subsidence was higher (28% vs. 7%, p=0.08). The inferior part of the cage was more vulnerable to subsidence compared with the superior part (median subsidence: 3.0 vs. 1.4 mm, psubsidence occurred more often when the end plate was removed rather than preserved (58% vs. 18%, psubsidence was greater after ACDF with cage alone. Cage subsidence occurred more often when the end plate was removed. Additional anterior plate fixation is recommended when the end plate is removed.

    To investigate the long-term outcome after unilateral adrenalectomy in patients with primary aldosteronism (PA) and to establish the role of functional pathology for the final diagnosis of aldosterone-producing adenoma (APA) or hyperplasia. A single-centre, retrospective cohort study in a hospital setting. Consecutive patients with PA, n = 120, who underwent unilateral adrenalectomy between 1985 and 2010. Preoperative and postoperative data were analysed. To indicate the site of aldosterone secretion in the resected adrenal, we added functional methods to routine histopathology, using in situ hybridization and immunohistochemistry to detect the presence of enzymes needed for aldosterone (CYP11B2) and cortisol (CYP11B1, CYP17A1) synthesis. The median follow-up was 5 years and the cure rate of PA 91%. Hypertension was improved in 97% and normalized in 38%. Functional histopathology changed the final diagnosis from APA to hyperplasia in 6 cases (7%). Five of these had no expression of or staining for aldosterone synthase in the adenoma, but only in nodules in the adjacent cortex. All except one APA patient were cured of PA. They had lower preoperative serum potassium and higher 24-h urinary aldosterone than patients with hyperplasia. Among patients with hyperplasia 16 of 26 were cured. Most patients were cured of PA by unilateral adrenalectomy. Almost all noncured benefitted from the operation as the blood pressure improved. Functional histopathology proved helpful in the distinction between APA and hyperplasia, and we recommend that functional histopathology should be added to routine histopathology to improve the diagnostic evaluation and aid in tailoring the follow-up. © 2014 John Wiley & Sons Ltd.

    Few data exist concerning sleep in patients with hemidiaphragm paralysis or weakness. Traditionally, such patients are considered to sustain normal ventilation in sleep. In the present study, diaphragm strength was measured in order to identify patients with unilateral paralysis or severe weakness. Patients underwent polysomnography with additional recordings of the transoesophageal electromyogram (EMG) of the diaphragm and surface EMG of extra-diaphragmatic respiratory muscles. These data were compared with 11 normal, healthy subjects matched for sex, age and body mass index (BMI). In total, 11 patients (six males, mean+/-sd age 56.5+/-10.0 yrs, BMI 28.7+/-2.8 kg x m(-2)) with hemidiaphragm paralysis or severe weakness (unilateral twitch transdiaphragmatic pressure 3.3+/-1.7 cmH(2)O (0.33+/-0.17 kPa) were studied. They had a mean+/-sd respiratory disturbance index of 8.1+/-10.1 events x h(-1) during non-rapid eye movement (NREM) sleep and 26.0+/-17.8 events x h(-1) during rapid eye movement (REM) sleep (control groups 0.4+/-0.4 and 0.7+/-0.9 events x h(-1), respectively). The diaphragm EMG, as a percentage of maximum, was double that of the control group in NREM sleep (15.3+/-5.3 versus 8.9+/-4.9% max, respectively) and increased in REM sleep (20.0+/-6.9% max), while normal subjects sustained the same level of activation (6.2+/-3.1% max). Patients with unilateral diaphragm dysfunction are at risk of developing sleep-disordered breathing during rapid eye movement sleep. The diaphragm electromyogram, reflecting neural respiratory drive, is doubled in patients compared with normal subjects, and increases further in rapid eye movement sleep.

    Orthodontic treatment planning of the cleft lip and palate vary according to the morphology of the alveolar bone and palatal bone. The purpose of this study is to evaluate the three-dimensional anatomy of the alveolar and palatal bone in children with complete unilateral cleft lip and palate. Thirty-three nonsyndromic consecutive patients with complete unilateral cleft lip and palate were treated by the cleft palate team at Showa University. Each patient had lip and palate surgeries at Showa University. Cone beam CT radiographs (CB MercuRay, Hitachi) were taken prior to secondary bone grafting, and were classified according to the method of Kita et al. 1997. Cone beam CT radiographs showed multiple types of alveolar and palatal bone morphology, and focused on special types described in the method of Kita et al. It was most frequently found that bone defects in the alveolar crest showed similar patterns in both buccal and palatal aspect, and the buccal bone defect in the nasal floor was larger than the palatal bone defect in the nasal floor. In 80% of the patients, the palatal bone defect showed similar patterns in both anterior and posterior aspects, and the anterior palatal bone defect was smaller than the posterior palatal bone defect. In addition, inadequate bone bridges were frequently found at the cleft site. It is suggested that patients with unilateral cleft lip and palate have various types of alveolar and palatal bone morphology, and are required to take three-dimensional radiographic X-rays prior to any orthodontic treatment.

    Full Text Available For patients with pharmaco-resistant temporal epilepsy, unilateral anterior temporal lobectomy (ATL - i.e. the surgical resection of the hippocampus, the amygdala, the temporal pole and the most anterior part of the temporal gyri - is an efficient treatment. There is growing evidence that anterior regions of the temporal lobe are involved in the integration and short-term memorization of object-related sound properties. However, non-verbal auditory processing in patients with temporal lobe epilepsy (TLE has raised little attention. To assess non-verbal auditory cognition in patients with temporal epilepsy both before and after unilateral ATL, we developed a set of non-verbal auditory tests, including environmental sounds. We could evaluate auditory semantic identification, acoustic and object-related short-term memory, and sound extraction from a sound mixture. The performances of 26 TLE patients before and/or after ATL were compared to those of 18 healthy subjects. Patients before and after ATL were found to present with similar deficits in pitch retention, and in identification and short-term memorisation of environmental sounds, whereas not being impaired in basic acoustic processing compared to healthy subjects. It is most likely that the deficits observed before and after ATL are related to epileptic neuropathological processes. Therefore, in patients with drug-resistant TLE, ATL seems to significantly improve seizure control without producing additional auditory deficits.

    Full Text Available Objectives. Asymmetric facial appearance may originate from abnormalities of facial musculature or facial innervation. We describe clinical features of congenital hypoplasia of depressor anguli oris muscle in a child. Material and Methods. Chart of a 10-month-old female referred to a tertiary care pediatric hospital for assessment of facial paralysis was reviewed. Data included relevant history and physical examination, diagnostic work up, and management. Results. The child presented with asymmetric movement of lower lip since birth. Asymmetry of lower lip was more pronounced when she smiled and cried. Rest of the face movement was symmetric. On examination, the face appeared symmetric at rest. The child had inward deviation of right lower lip when she smiled. Facial nerve function, as determined by frowning/forehead, wrinkling, eye closure, nasolabial fold depth, and tearing, was symmetric. Magnetic resonance imaging of the temporal bones and internal auditory canals were within normal limits. Echocardiogram did not show cardiac abnormality. Auditory brainstem response showed no abnormality. Conclusions. Congenital hypoplasia of depressor anguli oris is a rare anomaly that causes asymmetric crying face. Pediatricians and otolaryngologists need to be cognizant of cardiac, head and neck, and central nervous system anomalies associated with congenital unilateral hypoplasia of depressor anguli oris.

    This study determines the prevalence of unilateral vision impairment (VI) and unilateral blindness to assist in policy formulation for eye health care services. To determine the prevalence and causes of unilateral VI and unilateral blindness in Australia. This cross-sectional population-based survey was conducted from March 2015 to April 2016 at 30 randomly selected sites across all strata of geographic remoteness in Australia. A total of 1738 indigenous Australians 40 years or older and 3098 nonindigenous Australians 50 years or older were included. The prevalence and causes of unilateral vision impairment and blindness, defined as presenting visual acuity worse than 6/12 and 6/60, respectively, in the worse eye, and 6/12 or better in the better eye. Of the 1738 indigenous Australians, mean (SD) age was 55.0 (10.0) years, and 1024 participants (58.9%) were female. Among the 3098 nonindigenous Australians, mean (SD) age was 66.6 (9.7) years, and 1661 participants (53.6%) were female. The weighted prevalence of unilateral VI in indigenous Australians was 12.5% (95% CI, 11.0%-14.2%) and the prevalence of unilateral blindness was 2.4% (95% CI, 1.7%-3.3%), respectively. In nonindigenous Australians, the prevalence of unilateral VI was 14.6% (95% CI, 13.1%-16.3%) and unilateral blindness was found in 1.4% (95% CI, 1.0%-1.8%). The age-adjusted and sex-adjusted prevalence of unilateral vision loss was higher in indigenous Australians than nonindigenous Australians (VI: 18.7% vs 14.5%; P = .02; blindness: 2.9% vs 1.3%; P = .02). Risk factors for unilateral vision loss included older age (odds ratio [OR], 1.60 for each decade of age for indigenous Australians; 95% CI, 1.39-1.86; OR, 1.65 per decade for nonindigenous Australians; 95% CI, 1.38-1.96), very remote residence (OR, 1.65; 95% CI, 1.01-2.74) and self-reported diabetes (OR, 1.52; 95% CI, 1.12-2.07) for indigenous Australians, and having not undergone an eye examination in the past 2 years for nonindigenous

    By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

    Sudden sensorineural hearing loss (SSNHL) is generally defined as sensorineural hearing loss of 30 dB or greater over at least three contiguous audiometric frequencies and within a three-day period. This hearing loss is usually unilateral and can be associated with tinnitus and vertigo. The pathogenesis of unilateral sudden sensorineural hearing loss is still unknown, and the alterations in the functional connectivity are suspected to involve one possible pathogenesis. Despite scarce findings with respect to alterations in brain functional networks in unilateral sudden sensorineural hearing loss, the alterations of the whole brain functional connectome and whether these alterations were already in existence in the acute period remains unknown. The aim of this study was to investigate the alterations of brain functional connectome in two large samples of unilateral sudden sensorineural hearing loss patients and to investigate the correlation between unilateral sudden sensorineural hearing loss characteristics and changes in the functional network properties. Pure tone audiometry was performed to assess hearing ability. Abnormal changes in the peripheral auditory system were examined using conventional magnetic resonance imaging. The graph theoretical network analysis method was used to detect brain connectome alterations in unilateral sudden sensorineural hearing loss. Compared with the control groups, both groups of unilateral SSNHL patients exhibited a significantly increased clustering coefficient, global efficiency, and local efficiency but a significantly decreased characteristic path length. In addition, the primary increased nodal strength (e.g., nodal betweenness, hubs) was observed in several regions primarily, including the limbic and paralimbic systems, and in the auditory network brain areas. These findings suggest that the alteration of network organization already exists in unilateral sudden sensorineural hearing loss patients within the acute period

    Facial development of patients with unilateral complete cleft lip and palate (UCLP) is associated with many problems including deformity of the palate. The aim of this study was to evaluate palatal morphology and variability in patients with UCLP compared with Czech norms using methods of geometric morphometrics. The study was based on virtual dental cast analysis of 29 UCLP patients and 29 control individuals at the age of 15 years. The variability of palatal shape in UCLP patients was greater than that in nonclefted palates. Only 24% of clefted palates fell within the variability of controls. The palatal form of UCLP patients (range from 11.8 to 17.2 years) was not correlated with age. Compared with control palates, palates of UCLP patients were narrower, more anteriorly than posteriorly. Apart from the praemaxilla region, they were also shallower, and the difference increased posteriorly. The UCLP palate was characterised by the asymmetry of its vault. The maximum height of the palatal vault was anterior on the clefted side, whereas it was posterior on the nonclefted side. The slope of the UCLP palate was more inclined compared with the control group. The praemaxilla was therefore situated more inferiorly.

  14. Toxic anterior segment syndrome following deep anterior lamellar keratoplasty

    Directory of Open Access Journals (Sweden)

    Neslihan Sevimli

    Full Text Available ABSTRACT We present the case of a 31-year-old patient with toxic anterior segment syndrome (TASS that developed after undergoing deep anterior lamellar keratoplasty (DALK. She had keratoconus, and despite wearing hard contact lenses for many years in the left eye, her vision had deteriorated; therefore, DALK was performed on this eye. The preoperative visual acuity (VA was finger counting at 3 m. Routine DALK was performed using the "big-bubble" technique. The corneal entry incision was hydrated at the end of the surgery, which was terminated by air injection into the anterior chamber. On postoperative day 1, VA was at the level of hand movements, and the cornea was edematous. Topical high-dose dexamethasone and oral steroids were initiated considering the diagnosis of TASS. Subsequently, the patient's VA increased, and the corneal edema decreased. We believe that the use of re-sterilized cannulas may have been the likely cause of TASS. Although DALK can be performed without interfering with the anterior chamber, one should keep in mind that TASS may occur in response to the solution used to hydrate the incision site and the air injected into the anterior chamber.

    Anterior knee pain is a common musculoskeletal condition amongst young adult population. Lower extremity structural factors, such as increased femoral anteversion and lateral tibial torsion, may contribute to patellofemoral malalignment and anterior knee pain. The aim of this study was to evaluate the lower extremity structural factors and related patellofemoral alignment parameters that play a role in the aetiology of anterior knee pain. This study involved three groups: patients with unilateral symptomatic knees (n = 35), asymptomatic contralateral knees in the same patients and a control group (n = 40). All subjects were physically examined, and Q-angles were measured. The lower extremities of all subjects were imaged by a very low-dose CT scan, and the symptomatic knees of patients were compared with their asymptomatic contralateral knees and with the healthy knees of controls regarding femoral anteversion, tibial torsion, sulcus angle, patellar tilt angle and lateral patellar displacement. Regarding the Q-angle, femoral anteversion and lateral tibial torsion, no significant differences were found between the symptomatic and asymptomatic knees, whereas significant differences were found between the symptomatic knees and controls. The symptomatic group demonstrated significantly greater sulcus angle only in 30° of knee flexion than did the controls. Patients with unilateral anterior knee pain may have similar morphology at their contralateral asymptomatic lower extremity, and different morphology compared with healthy controls. Lower extremity rotational deformities may increase the risk of anterior knee pain; however, these deformities alone are not sufficient to cause knee pain, and may be predisposing factor rather than a direct aetiology.

    Gynecomastia is defined as the excessive development of breast tissue in males, which can occur as unilateral or bilateral. Although the overall prevalence of gynecomastia is 40%-65%, the prepubertal unilateral gynecomastia in the absence of endocrine abnormalities is unusual, with only a few case reports in literature. Idiopathic gynecomastia in prepuberty is benign but a diagnosis of exclusion. We here report two cases of healthy prepubertal boys aged 8.8 and 9.6 years old, respectively, pr...

    The surgical treatment of patients with neglected developmental dysplasia of the hip (DDH) has been the subject of controversy. We asked if age affected outcome in patients with neglected DDH with unilateral or bilateral dislocation who underwent one-stage combined procedures. We retrospectively reviewed the results of 40 patients (51 hips) treated with a one-stage combined procedure consisting of open reduction, pelvic osteotomy, and femoral shortening. The average age at the time of surgery was 5.4 years for Group I (bilateral dislocation, 22 hips) and 6.7 years for Group II (unilateral dislocation, 29 hips). Mean followup was 5.4 years for Group I and 6.7 years for Group II. According to the modified score system of Trevor et al, 13 hips rated excellent, three were good, and six were fair in Group I; the ratings were 14, nine, and six hips respectively in Group II. Four patients had a limb-length discrepancy of approximately 1.5 cm in Group I. Twelve hips in Group I and 18 hips in Group II had osteonecrosis of varying severity. Our data suggest the outcomes of the children who were 5.5 years or younger in Group I and 8 years or younger in Group II were better. Level IV, case series.

    2012-02-01

    Full Text Available Abstract Unilateral papillitis caused by Treponema pallidum was found in an immunocompetent homosexual patient with severe vision loss who had received previous antibiotics treatment. Syphilis-related ocular manifestation is more common in the early stages of the disease and it can be associated with a central nervous system localization. In this patient, neurosyphilis was diagnosed on the basis of clinical and laboratory findings. Optical examination revealed unilateral papillitis in the left eye and no relative afferent pupillary defects. The patient underwent visual field examinations with conventional perimetry using the 30-2 program of the Humphrey Visual Field Analyzer, which indicated a blind spot enlargement in the left eye. Optical coherence tomography, visual evoked potentials (VEP, and fluorescein angiograms revealed inflammation of the optic nerve head with edematous and blurred margins. A reactive T. pallidum hemagglutination assay with low rapid plasma reagin (RPR serum titer was performed; an HIV antibody test and MRI of the orbits and head with contrast gave negative results. Resolution of the ocular inflammation after intravenous penicillin treatment was obtained. The reported case illustrates the importance of early recognition of this treatable disease. The rise of syphilis, especially in urban areas, necessitates a high level of suspicion when dealing with patients with intraocular inflammation of unknown origin. Lues serology should be incorporated into routine laboratory diagnostics to aid in the detection of such cases. Considering the re-emergence of syphilis, screening of migrants from countries with high syphilis seroprevalences should be recommended.

    As HRCT (high resolution computed tomography) has become increased commonly used, it has become apparent that GGA (ground-glass attenuation) is present in a variety of lung diseases. We report a case of unilateral lung edema represented as GGA in an opposite lung field after treatment of pulmonary adenocarcinoma. A 70-year-old man with uncontrolled diabetes was admitted because of an abnormal shadow discovered during a routine chest X-ray in June 2003. In 1994, he underwent a left lower lobectomy and post-operative mediastinal radiation for pulmonary adenocarcinoma (p-Stage IIIA). Chest CT on admission demonstrated widespread GGA in the right hilar lesion of the middle and lower lobes. Detailed examinations including transbronchial lung biopsy (TBLB), bacterial culture and a serological test could not confirm bronchioloalveolar carcinoma, interstitial pneumonia, viral pneumonia or alveolar proteinosis. The patient increased his weight by 5 kg and ultrasound examination showed dilatation of the inferior vena cava and a congestive liver. The GGA disappeared one month after the administration of furosemide. The clinical course, HRCT and pathological findings suggested that lung edema caused by volume overload affected as localized unilateral GGA in the chest CT. The decrease in pulmonary vessel beds due to surgical resection, obstruction of lymphatic circulation after mediastinal radiation, and increased permeability of microvessels associated with diabetes are supposed to be linked to lung edema. Localized lung edema should be considered as a possible cause of GGA after lung cancer treatment. (author)

    Fibroadenomas are a type of benign tumor that occur in young women below the age of 35 years old. The tumors are the second most common type of tumor after fibrocystic disease. The chance of carcinoma arising in a fibroadenoma is extremely low. To date, fibroadenomas can evolve into a number of different types of malignancy. The present study is the first to describe a case of bilateral primary breast cancer with a unilateral invasive ductal carcinoma within a fibroadenoma. The current study presents a case of a 48-year-old female who presented with 2 stiff lumps on bilateral breasts, diagnosed as bilateral breast carcinoma, with a unilateral invasive ductal carcinoma within a fibroadenoma in the right breast. The patient underwent a bilateral mastectomy and subsequently received 4 cycles of chemotherapy (epirubicin, 60 mg/m2 and cyclophosphamide, 600 mg/m2) every 21 days, followed by 4 cycles of docetaxel chemotherapy (100 mg/m2) every 21 days. The patient then received maintenance endocrine therapy (tamoxifen, 20 mg, twice daily) for 19 months. The patient was followed up every 3 months, and at the last follow-up examination in May 2015, the patient exhibited no signs of recurrence. PMID:26622700

  6. Comparative analysis of pain in patients who underwent total knee replacement regarding the tourniquet pressure

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

    There are increasingly more patients seeking minimally invasive procedures, which have become more effective and safer in reducing the signs of facial aging. This study included 40 female adult patients who voluntarily underwent selected minimally invasive procedures (filling with hyaluronic acid and botulinum toxin injection) for facial rejuvenation. All patients were followed for a period of 6 months. They were evaluated with the use of questionnaires, a quality-of-life questionnaire (DLQI), the self-esteem scale of Rosenberg (EPM/Rosenberg), and a pain scale. The minimally invasive procedures resulted in improvement in quality of life and self-esteem, which were stronger the first 3 months after the procedures but remained at a higher level than that before treatment, even after 6 months. Hyaluronic acid with lidocaine in the formula is more comfortable for the patient as it makes the injection less painful.

    Basal and squamous cell carcinomas are the most common malignant cutaneous lesions affecting the nose. With the rising incidence of skin cancers, plastic surgeons increasingly face nasal reconstruction challenges. Although multiple options exist, optimal results are obtained when "like is used to repair like". We aimed to introduce a simple algorithm for the reconstruction of nasal defects with local flaps, realizing that there is always more than one option for reconstruction. We retrospectively reviewed 163 patients who underwent nasal reconstruction after excision of non-melanoma skin cancer between March 2011 and April 2014. We analyzed the location of the defects and correlated them with the techniques used to reconstruct them. There were 66 males and 97 females (age, 21-98 years). Basal cell carcinoma was diagnosed in 121 patients and squamous cell carcinoma in 42. After tumor excision, all the defects were immediately closed by either primary closure or local flap options such as Limberg, Miter, glabellar, bilobed, nasolabial, V-Y advancement, and forehead flaps. Obtaining tumor-free borders and a pleasing aesthetic result are major concerns in nasal reconstruction. Defect reconstruction and cosmesis are as important as rapid recovery and quick return to normal daily activities, and these should be considered before performing any procedure, particularly in elderly patients.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

  10. Influence of perioperative administration of amino acids on thermoregulation response in patients underwent colorectal surgical procedures

    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

    To determine the prevalence and spontaneous resolution of congenital hydrocele diagnosed in male neonates who underwent circumcision at our centre. All male neonates presented for circumcision at the University of Benin Teaching Hospital, Benin City, Nigeria between January 2002 and December 2006 were examined for the presence of hydrocele. Those diagnosed with this condition were recruited and followed up in a surgical outpatient clinic for 2 years. The number of cases of spontaneous resolution and age at which this occurred were documented on a structured pro forma. A total of 2715 neonates were circumcised and 128 (4.7%) were diagnosed with 163 cases of hydrocele, while 27 cases in 25 (0.9%) children failed to resolve at the age of 2 years. Neonatal hydrocele was bilateral in 112 (68.7%), and there were 20 (12.3%) right and 31 (19.0%) left. Among those with hydrocele, 28.1% were delivered preterm and resolution was spontaneous in many of them, with no observed significant statistical difference to those delivered full term (P=0.4740). Of the 163 hydrocele cases, 136 (83.4%) resolved spontaneously by age 18 months with peak resolution at 4-6 months. No spontaneous resolution occurred after 18 months and no hydrocele-related complication occurred during follow up. Neonates with congenital hydrocele should be observed for spontaneous resolution for at least 18 months before being subjected to surgery.

    To describe the psychological stress and quality of life experienced by women who underwent fertility treatment in Taiwan. Cross-sectional, correlational study. Recruitment was conducted and questionnaires administered at a reproductive medicine center in Chiayi City, Taiwan. Informed consent to participate was obtained from 126 women who sought fertility treatment at the center. The Chinese Fertility Problem Inventory and Fertility Quality of Life scale were used to measure participants' levels of fertility-related stress and fertility-related quality of life. Descriptive statistics, correlation, and regression analysis were used. Overall, participants reported low levels of fertility-related stress and fertility-related quality of life; however, they had relatively high levels of stress related to need for parenthood. Women who were older, had greater body mass indexes, and consumed coffee regularly had lower fertility-related quality of life. Social and relationship concerns and stress related to need for parenthood were significant predictors of low fertility-related quality of life. In a culture in which childbearing is generally an expectation and an important part of family life, women who experience infertility are at risk to experience fertility-related stress. Social support and family consultation might be offered to improve women's fertility-related quality of life.

    Full Text Available Objective To study the clinical manifestations, pathologic features, diagnosis, treatment and prognosis of primary synovial sarcoma in the anterior mediastinum. Methods A case of primary synovial sarcoma in the anterior mediastinum was reported. Clinical features, imaging manifestations, pathology features and therapeutic effect were analysed and the relevant literature was reviewed. Results A 48-year-male patient was admitted with complaint of right chest pain for 4 days. Chest computerized tomography revealed a large mass located at the right anterior mediastinum, and it was primarily diagnosed as invasive thymoma. Pathological examination by CT-guided percutaneous needle biopsy manifested that, under microscope, the tumor cells were short and spindle in shape forming a nest structure, suggested it was a thymoma. The patient then underwent resection of thymoma with removal of fat and connective tissue in the anterior mediastinum. During the operation the size of the tumor was 15cm×15cm×10cm, being located at the anterior mediastinum, and it tended to bleed. The diagnosis of primary monophasic synovial sarcoma in the mediastinum was confirmed by postoperative/pathology examination. Immunohistochemistry staining showed that the tumor cells were positive for the markers Bcl-2 and EMA, but negative for the markers CK (pan and S100. The patient suffered from local recurrence with metastases to lung 4 months after surgery. The patient received 2 chemotherapeutic courses with ifosfamide, epirubicin and cisplatin. He died 6 months after surgery. Conclusion Primary synovial sarcoma in the anterior mediastinum is an extremely rare and highly malignant tumor with poor prognosis. The diagnosis depends on the pathological features, immunohistochemistry and RT-PCR. Radical resection combined with comprehensive treatment may improve the survival rate.

    Unilateral lichen planus (LP) is a rare clinical variant of LP. The etiology of unilateral LP has not been clarified, although various causes have been reported because of the characteristic distribution. We focused on the contribution of metal allergy and sweating in the development of unilateral LP in this case. To confirm the presence of metal allergy, patch tests with metal allergens were performed. To investigate the cause of the unilateral distribution in unilateral LP, the function of sweating and sweat leaking in the dermis was assessed by a thermoregulatory sweat test and immunohistochemical staining of dermcidin. The patch tests with SnCl 2 , H 2 PtCl 6 , ZnCl 2 and MnCl 2 were positive. The thermoregulatory sweat test using the starch-iodine method (Minor test) with sweating provoked by heat stimulation revealed hypohidrosis of the affected area, whereas no skin lesions were observed on the dorsal hand and wrist where sweating was normal. Histopathological examination showed keratin plugging of the acrosyringium and lymphocytic infiltrations in the papillary and subpapillary dermis around the intraepidermal and intradermal eccrine duct in the affected area. The immunohistochemical staining of dermcidin confirmed sweat leakage in the subpapillary dermis in the affected area. The symptoms refractory to the topical steroids were markedly improved after removal of the dental metals. The coexistence of metal allergy and sweat leakage in the hypohidrotic area may be involved in the development of unilateral LP. © 2017 Japanese Dermatological Association.

    2016-01-01

    Full Text Available Asymmetric ventriculomegly due to idiopathic occlusion of the foramen of Monro is rare. Such patients present with clinical features of raised intracranial pressure (ICP. Presentation as chronic headache has not been previously described. In the absence of raised ICP, pursuing surgical treatment raises a clinical dilemma as the headache may be a primary headache with no improvement after surgery. A 21-year-old woman presented with chronic headache. She was found to have asymmetric ventriculomegaly due to the occlusion of the foramen of Monro. She underwent endoscopic septostomy and widening of the foramen of Monro. Her headache subsided after surgery. At 15 months of follow-up, she was free from headache without medications. Unilateral occlusion of the foramen of Monro can present with asymmetric ventriculomegaly resulting in chronic headache. Though the symptoms of raised ICP may not be present, still endoscopic relief of ventriculomegaly leads to cure of headache.

    Objectives The aim of this study was to evaluate a possible relationship between preferred chewing side (PCS) and the anterior guidance angle. Subjects and Methods Forty dental nurses and technicians, aged 24–46 years, were each given a piece of chewing gum, which they chewed for about 3 min. At 7 regular intervals (every 15 s), they were interrupted by the principal investigator (P.L.) in order to observe on which side of their mouths they had the bolus of chewing gum. Moulds of their jaws were made and the position of the maxillary arch relative to temporomandibular joints was recorded with a facebow and transferred to a semi-adjustable articulator. After mounting the stone casts of each subject, a measure of the anterior guidance angle was taken with an adjustable incisal table. Results Of the 40 subjects, 14 (35%) presented a PCS. Among the 14 subjects who preferred a chewing side, there was a correlation between the PCS and a low angulation of teeth constituting the anterior guidance on that side, but this correlation was statistically nonsignificant. Conclusion In this study, we found that unilateral chewing creates uneven wear on the anterior teeth and changed the anterior guidance angulation. PMID:23948666

    Full Text Available Purpose: To study the efficacy and safety of 0.1% Trypan Blue dye to stain the anterior capsule for capsulorhexis in mature and hypermature cataracts. Methods: This preliminary study included 25 eyes of 25 patients with a unilateral mature or hypermature cataract, including one case of traumatic mature cataract. In all these cases 0.2ml of 0.1% trypan blue dye was used to stain the anterior capsule. The efficacy and safety of the dye was evaluated on the basis of intraoperative and postoperative observations. Results: In all 25 eyes the capsulorhexis was completed. There was peripheral extension of the capsulorhexis in the eye with traumatic cataract and the stained edge of the anterior capsule helped identification and redirection of the capsulorhexis. Successful phacoemulsification with intraocular lens implantation was performed in all eyes. Adverse reactions related to the dye such as raised intraocular pressure, anterior chamber inflammation and endothelial damage were not observed in the immediate postoperative period or at the end of mean follow-up of 3 months. Conclusion: Trypan blue dye staining of the anterior capsule appears to be a very useful and safe technique that simplifies capsulorhexis in mature and hypermature cataracts.

    Lateral cephalometry has been widely used to characterize facial and maxillary morphology in obstructive sleep apnea (OSA) patients. It is a useful tool to assess orthodontic and maxillofacial procedures, but transverse dimensions of the airway (e.g., nasal framework) have not been well described yet by cephalometry. We explored whether postero-anterior cephalometry could refine the analysis of the facial morphology, with a special attention paid to nasal morphology. We validated cephalometric measurements relevant to the diagnosis of OSA. Controlled study. We explored postero-anterior and lateral cephalometric bony structures in OSA patients and in control subjects to determine which were predictive of an association with OSA. Healthy volunteers paired for age and sex to OSA patients underwent polysomnography and cephalometry. Data were analyzed by Shapiro-Wilk, Fisher, Wilcoxon, and paired t tests where appropriate. Nasal fossae and maxillary bone proportions were positively and independently associated with the absence of OSA. Measurements of maxillary width, nasal fossae angle, and anterior skull base contributed to the characterization of OSA patients. Postero-anterior cephalometry is an easy, rapid, informative, and reliable technique, which is complementary to the lateral cephalometry in the assessment of OSA patients. Our study may also suggest the negative impact of the nasal resistance on the upper airway resistance in sleep disorders.

    To report our experience with "loop overlay" tympanoplasty, a modified overlay technique with a superiorly based skin flap, for the reconstruction of anterior, subtotal or total tympanic membrane (TM) perforations. Retrospective review of patients undergoing loop overlay tympanoplasty from March 1998 to February 2007 was performed. Four hundred and twenty-nine patients who underwent loop overlay tympanoplasty and then follow-up visits a minimum of 6 months later were included in this study. Hearing test results were reported using a four-frequency (0.5, 1, 2, and 3kHz) pure tone average air-bone gap. The outcome was considered successful if the TM was intact without lateralization or anterior blunting after the follow-up visit. There was a 98.8% success rate. There was no graft lateralization, anterior blunting, neocholesteatoma, or sensorineural hearing loss. The mean preoperative to postoperative four-tone air-bone gap improved from 23.5 to 8.1dB, which is a mean gain of 15dB; this was statistically significant (poverlay graft method is a safe and effective technique for reconstruction of anterior, subtotal or total TM perforations, with excellent graft take and significant improvement of hearing. It provides a precise replacement of the flap and a preserved healing plane. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

    The aim of this study was to evaluate the long-term outcomes of four patients with tracheal agenesis who underwent airway and esophageal/alimentary reconstruction. We reviewed the medical records of four long-term survivors of tracheal agenesis and collected the following data: age, sex, type of tracheal agenesis, method of reconstruction, nutritional management, and physical and neurological development. The patients consisted of three boys and one girl, who ranged in age from 77 to 109months. The severity of their condition was classified as Floyd's type I (n=2), II (n=1), or III (n=1). Mechanical respiratory support was not necessary in any of the cases. Esophageal/alimentary reconstruction was performed using the small intestine (n=2), a gastric tube (n=1), and the esophagus (n=1). The age at esophageal reconstruction ranged from 41 to 55months. All of the cases required enteral nutrition via gastrostomy. Three of the patients were able to swallow a small amount of liquid and one was able to take pureed food orally. The physical development of the subjects was moderately delayed-borderline in childhood. Neurological development was normal in two cases and slightly delayed in two cases. None of the long-term survivors of tracheal agenesis required the use of an artificial respirator, and their development was close to normal. Future studies should aim to elucidate the optimal method for performing esophageal reconstruction to allow tracheal agenesis patients to achieve their full oral intake.

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB. Future prospective studies are needed to further explore the prevalence, predictors, and mechanisms of weight regain after RYGB. Copyright © 2016 American Society for Bariatric Surgery.

    Video thoracoscopic sympathectomy is the recommended surgical treatment for primary hyperhidrosis and has a high success rate. Despite this high success rate, some patients are unresponsive and eventually need a resympathectomy. Few studies have previously analysed exclusively the results of these resympathectomies in patients with primary hyperhidrosis. None of the studies have objectively evaluated the degree of response to surgery or the improvement in quality of life after resympathectomies. This is a retrospective study, evaluating 15 patients from an initial group of 2300 patients who underwent resympathectomy after failure of the primary surgical treatment. We evaluated sympathectomy levels of resection, technical difficulties, surgical complications preoperative quality of life, response to treatment and quality-of-life improvement 30 days after each surgery. Regarding gender, 11 (73.3%) patients were women. The average age was 23.2 with SD of 5.17 years, and the mean body mass index was 20.9 (SD 2.12). Ten patients had major complaints about their hands (66%) and 5 (33%) patients about their forearms. A high degree of response to sympathectomy occurred in 73% of patients. In 11 of these patients, the improvement in quality of life was considered high, 3 showed a mild improvement and 1 did not improve. No major complications occurred; the presence of adhesions was reported in 11 patients and pleural drainage was necessary in 4 patients. Resympathectomy is an effective procedure, and it improves the quality of life in patients with primary hyperhidrosis who failed after the first surgery. © The Author 2017.

    The study objective was to report the outcomes of biventricular repair in patients with double outlet right ventricle. Patients with double outlet right ventricle who underwent biventricular repair at Fuwai Hospital from January 2005 to December 2012 were included. Patients were excluded if double outlet right ventricle was combined with atrioventricular septal defect, heterotaxy syndrome, atrioventricular discordance, or univentricular physiology. A total of 380 consecutive patients with a mean age of 1.9 ± 2.1 years (range, 1 month to 6 years) were included. Varied types of biventricular repair were customized individually. Follow-up was 90.4% complete, and the mean follow-up time was 3.4 ± 3.9 years. There were 17 (4.5%) early deaths and 7 (2.1%) late deaths. Preoperative pulmonary hypertension was the only risk factor for early mortality. Postoperative significant left ventricular outflow tract obstruction was present in 9 survivors. Patients with noncommitted ventricular septal defect had a longer crossclamp time, longer cardiopulmonary bypass time, and higher incidence of postdischarge left ventricular outflow tract obstruction. There were 4 reoperations, all of which were caused by subaortic left ventricular outflow tract obstruction. All of the pressure gradients were decreased to less than 20 mm Hg after the modified Konno procedure with an uneventful postoperative course. Optimal results of varied types of biventricular repair for double outlet right ventricle have been acquired. Although noncommitted ventricular septal defect is technically difficult, the outcomes of patients are favorable. Late-onset left ventricular outflow tract obstruction is the main reason for reoperation but can be successfully relieved by the modified Konno procedure.

    Full Text Available The relationship between a perioperative change in sarcopenic status and clinical outcome of liver transplantation (LT is unknown. We investigated whether post-LT sarcopenia and changes in sarcopenic status were associated with the survival of patients.This retrospective study was based on a cohort of 145 patients from a single transplant center who during a mean of 1 year after LT underwent computed tomography imaging evaluation. The cross-sectional area of the psoas muscle of LT patients was compared with that of age- and sex-matched healthy individuals. The Cox proportional hazards regression model was used to determine whether post-LT sarcopenia and changes in sarcopenic status affect post-LT survival.The mean age at LT of the 116 male and 29 female patients was 50.2 ± 7.9 years; the mean follow-up duration was 51.6 ± 32.9 months. All pre-LT patients with sarcopenia still had sarcopenia 1 year after LT; 14 (15% patients had newly developed sarcopenia. The mean survival duration was 91.8 ± 4.2 months for non-sarcopenic patients and 80.0 ± 5.2 months for sarcopenic patients (log-rank test, p = 0.069. In subgroup analysis, newly developed sarcopenia was an independent negative predictor for post-LT survival (hazard ratio: 10.53, 95% confidence interval: 1.37-80.93, p = 0.024.Sarcopenia in LT recipients did not improve in any of the previously sarcopenic patients and newly developed within 1 year in others. Newly developed sarcopenia was associated with increased mortality. Newly developed sarcopenia can be used to stratify patients with regard to the risk of post-LT mortality.

  7. Unilateral spatial neglect after posterior parietal damage.

    2018-01-01

    Unilateral spatial neglect is a disabling neurologic deficit, most frequent and severe after right-hemispheric lesions. In most patients neglect involves the left side of space, contralateral to a right-hemispheric lesion. About 50% of stroke patients exhibit neglect in the acute phase. Patients fail to orient, respond to, and report sensory events occurring in the contralateral sides of space and of the body, to explore these portions of space through movements by action effectors (eye, limbs), and to move the contralateral limbs. Neglect is a multicomponent higher-level disorder of spatial awareness, cognition, and attention. Spatial neglect may occur independently of elementary sensory and motor neurologic deficits, but it can mimic and make them more severe. Diagnostic tests include: motor exploratory target cancellation; setting the midpoint of a horizontal line (bisection), that requires the estimation of lateral extent; drawing by copy and from memory; reading, assessing neglect dyslexia; and exploring the side of the body contralateral to the lesion. Activities of daily living scales are also used. Patients are typically not aware of neglect, although they may exhibit varying degrees of awareness toward different components of the deficit. The neural correlates include lesions to the inferior parietal lobule of the posterior parietal cortex, which was long considered the unique neuropathologic correlate of neglect, to the premotor and to the dorsolateral prefrontal cortices, to the posterior superior temporal gyrus, at the temporoparietal junction, to subcortical gray nuclei (thalamus, basal ganglia), and to parietofrontal white-matter fiber tracts, such as the superior longitudinal fascicle. Damage to the inferior parietal lobule of the posterior parietal cortex is specifically associated with the mainly egocentric, perceptual, and exploratory extrapersonal, and with the personal, bodily components of neglect. Productive manifestations, such as

    The purpose of this study was to compare the posterior dynamic imaging with the anterior imaging in the evaluation of children with gastroesophageal reflux (GER). Sixty-eight children (26 female, 42 male; age range 4 months to 7 years, median 21 months) were studied. After 4-hour fasting, all the subjects underwent gastroesophageal scintigraphy. Synchronous dynamic imaging in the anterior and posterior projections was performed with the subject in the supine position with a dual-head gamma camera equipped with low-energy general-purpose collimators at a rate of 30 s/frame for 40 min. The anterior and posterior images were visually evaluated for the presence of gastroesophageal reflux by two nuclear medicine physicians. The anterior and posterior images were correlated by Pearson correlation analysis, and inter-observer variability was evaluated by paired t-test and kappa value. There was a good correlation between the two projections with r-values of 0.906-0.990. The inter-observer agreement for interpretation of the anterior and posterior imaging was excellent (k: 0.83). In conclusion, anterior and posterior dynamic imaging showed excellent correlation in detection of GER in children. Posterior imaging is superior to anterior imaging in that it is more comfortable, and it reduces motion artifacts, especially for infants and anxious children; thus, it may be preferred over anterior imaging.

    SEE LEONE AND PROIETTI CECCHINI DOI101093/AWW233 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: Short-lasting unilateral neuralgiform headache attacks are primary headache disorders characterized by short-lasting attacks of unilateral pain accompanied by autonomic features. A small minority are refractory to medical treatment. Neuroimaging studies have suggested a role of the posterior hypothalamic region in their pathogenesis. Previous case reports on deep brain stimulation of this region, now understood to be the ventral tegmental area, for this disorder are limited to a total of three patients. We present a case series of 11 new patients treated with ventral tegmental area deep brain stimulation in an uncontrolled, open-label prospective observational study. Eleven patients with refractory short-lasting unilateral neuralgiform headache attacks underwent ipsilateral ventral tegmental area deep brain stimulation in a specialist unit. All patients had failed, or been denied access to, occipital nerve stimulation within the UK's National Health Service. Primary endpoint was change in mean daily attack frequency at final follow-up. Secondary outcomes included attack severity, attack duration, headache load (a composite score of attack frequency, severity and duration), quality of life measures, disability and affective scores. Information was also collected on adverse events. Eleven patients (six male) with a median age of 50 years (range 26-67) were implanted between 2009 and 2014. Median follow-up was 29 months (range 7-63). At final follow-up the median improvement in daily attack frequency was 78% (interquartile range 33%). Response rate (defined as at least a 50% improvement in daily attack frequency) was 82% and four patients were rendered pain-free for prolonged periods of time. Headache load improved by 99% (interquartile range 52%). Improvements were observed in a number of quality of life, disability and affect measures. Adverse events included mild incision

    Twenty mongrel dogs received 6000 rads of irradiation to the rectum and colon using the Nominal Standard Dosage Equation. Three weeks after irradiation each dog underwent anterior resection of the rectosigmoid with reconstruction randomized to either an EEA stapled or a two layer handsewn anastomosis. Each dog was studied digitally and by barium enema at the time of surgery, on the seventh postoperative day, and at autopsy. Five clinically significant leaks and three radiographic leaks occurred in the EEA stapled anastomoses. The handsewn anastomoses had five clinically significant leaks and two radiographic leaks. The data indicate that low anterior resection with either an EEA stapled or handsewn anastomosis cannot be done safely after 6000 rad preoperative irradiation.

    To investigate the effectiveness of unilateral posterior semicircular canal (PSCC)-plugging surgery for patients with intractable bilateral PSCC-type benign paroxysmal positional vertigo (P-BPPV). From July 2011 to December 2015, we diagnosed 136 patients with P-BPPV. Of these, 3 patients had bilateral P-BPPV, and in 2 of the 3, the condition had been refractory to conservative treatment for more than 1 year. We planned a staged PSCC-plugging surgery for these 2 patients; initially one side was treated, and the contralateral side was treated 6 months later. After the first surgery, both patients experienced improvement in symptoms of vertigo and nystagmus on the operated side and no change on the non-operated side. Patients underwent the Epley maneuver for the non-operated side. In one case, the non-operated side was cured. In the other case, although the P-BPPV was not completely resolved, the patient was satisfied with the result of unilateral surgery because he was now able to turn in bed to the operated side without vertigo. Before surgery, he had experienced vertigo when turning even slightly in bed. We propose that even unilateral PSCC-plugging surgery is effective for some patients with intractable bilateral P-BPPV.

    Injecting dextranomer/hyaluronic acid copolymer has gained popularity as first line treatment for vesicoureteral reflux. However, ureteroneocystostomy has typically been more successful than endoscopic treatments. We evaluated the outcome of dextranomer/hyaluronic acid copolymer injection vs that of extravesical ureteroneocystostomy via a 2 cm inguinal incision (mini-ureteroneocystostomy) for unilateral vesicoureteral reflux. The records were analyzed of all patients from 2003 to 2007 with unilateral vesicoureteral reflux who underwent mini-ureteroneocystostomy or dextranomer/hyaluronic acid copolymer injection. Mini-ureteroneocystostomy was performed via a 2 cm inguinal incision. Of the injections 66% were delivered via an intraureteral tunnel technique. Statistical analysis was done to compare differences in clinical features and success rates. All p values were 2-sided with significance at p hyaluronic acid copolymer injection and 57 via mini-ureteroneocystostomy. There were no significant differences between the groups in terms of preoperative clinical or anatomical variables except for higher preoperative reflux grade in the mini-ureteroneocystostomy cohort (p hyaluronic acid copolymer cohort, while 2 children required intervention for complications after mini-ureteroneocystostomy. This study details that the 2 procedures may be successfully performed in the outpatient setting, and yet even for more advanced vesicoureteral reflux mini-ureteroneocystostomy achieves greater overall success. This procedure has become our standard of care for unilateral vesicoureteral reflux.

    1990-12-01

    The ethmoid air cell labyrinth lies adjacent to the medial orbital wall, extending even beyond the sutures of the ethmoid bone. Its anatomic relationship to the lacrimal sac fossa is important in lacrimal surgery. We evaluated computed tomographic scans of 190 orbits with normal ethmoid anatomy to define the anatomic relationship of anterior ethmoid air cells to the lacrimal sac fossa. In 93% of the orbits, the cells extended anterior to the posterior lacrimal crest, with 40% entering the frontal process of the maxilla. This anatomic relationship may be used to facilitate the osteotomy during dacryocystorhinostomy. During a 10-year period (310 cases), one of us routinely entered the anterior ethmoid air cells to initiate the osteotomy during dacryocystorhinostomy. This technique has helped to avoid lacerations of the nasal mucosa.

    Chronic anterior knee pain is the most common complication after tibial nail insertion. Its etiology remains unknown, and multifactorial sources have been suggested. The authors believe that nail prominence and the insertion point of the nail are important in the development of anterior knee pain. The purpose of this retrospective study was to evaluate the roles of the insertion point and nail prominence in anterior knee pain after tibial intramedullary nailing using a transtendinous approach and a common nail type. A total of 108 patients with tibial shaft fractures underwent reamed intramedullary nailing using a transtendinous approach between 2006 and 2009. Mean follow-up was 26.8±5.0 months. A visual analog scale (0-100) was used to estimate anterior knee pain severity while patients performed 7 activities retrospectively. Radiographic assessments, including nail prominence and insertion point, were performed. Sixty (55.6%) patients experienced knee pain (group P) and 48 (44.4%) did not (group N). Significant differences were not found between the groups with respect to demographics, nail diameters, or fracture classifications. Less superior and more anterior nail prominences in radiographic assessments were significantly associated with anterior knee pain. When the insertion point was over the bottom half of the anterior cortex, the influence of anterior nail prominence was more obvious. Nail removal resulted in diminished pain during the 7 assessed activities. Nail insertion should be over the bottom half of the anterior cortex, with minimal anterior nail prominence. If anterior knee pain occurs, removal of the nail should be considered. Copyright 2014, SLACK Incorporated.

    Full Text Available Septic arthritis of the knee is a rare complication after arthroscopic anterior cruciate ligament reconstruction, and the most appropriate treatment is unclear. All case series reported so far have been retrospective, and case numbers of septic arthritis have ranged from 4 to 11. From a consecutive case series of 1,283 patients who underwent arthroscopic anterior cruciate ligament reconstruction between January 1997 and May 2008, we report on 3 patients (0.23% with post-operative septic arthritis. All patients had acute infection (≤ 2 weeks, bacterial cultures showed Staphylococcus species in 2 patients, while the bacterial culture was negative in the third. All of them underwent immediate arthroscopic debridement and lavage with continuous irrigation, as well as antibiotic treatment. The results were evaluated with physical and radiographic examination, functional testing, KT-2000, Lysholm and Tegner scales. The infection was successfully eradicated without further surgical treatment and the ligament graft was retained in all patients. Follow-up, at an average of 33 months, revealed that the patients had full symmetric knee range of motion and no effusion. The average Lysholm score was 91 points. In the patient with a lower subjective score, radiographs demonstrated patellofemoral joint-space narrowing, which is most probably in correlation with his anterior knee pain problems and lower activity level. The 134 N KT-2000 arthrometer side-to-side differences averaged 13 mm. Their performance in the single-legged hop test gave excellent results. The goals of treatment for septic arthritis after anterior cruciate ligament reconstruction are, primarily, to protect the articular cartilage and, secondly, to protect the graft. Through early diagnosis and prompt treatment, the infection can be successfully eradicated, with stability of the knee and full range of motion achieved.

    The goal of this retrospective review was to determine whether fluoroscopic guidance improves acetabular cup abduction and anteversion alignment during anterior total hip arthroplasty. The authors retrospectively reviewed 199 patients (fluoroscopy group, 98; nonfluoroscopy group, 101) who underwent anterior total hip arthroplasty at a single center with and without C-arm fluoroscopy guidance. Included in the study were patients of any age who underwent primary anterior approach total hip arthroplasty performed by a single surgeon, with 6-month postoperative anteroposterior pelvis radiographs. Acetabular cup abduction and anteversion angles were measured and compared between groups. Mean acetabular cup abduction and anteversion angles were 43.4° (range, 26.0°-57.4°) and 23.1° (range, 17°-28°), respectively, in the fluoroscopy group. Mean abduction and anteversion angles were 45.9° (range, 29.7°-61.3°) and 23.1° (range, 17°-28°), respectively, after anterior total hip arthroplasty without the use of C-arm guidance (nonfluoroscopy group). The use of fluoroscopy was associated with a statistically significant difference in cup abduction (P=.002) but no statistically significant difference in anteversion angles. In the fluoroscopy group, 80% of implants were within the combined safe zone compared with 63% in the nonfluoroscopy group. A significantly higher percentage of both acetabular cup abduction angles and combined anteversion and abduction angles were in the safe zone in the fluoroscopy group. Fluoroscopy is not required for proper anteversion placement of acetabular components, but it may increase ideal safe zone placement of components. Copyright 2015, SLACK Incorporated.

    To evaluate the efficiency of navigation system for orbital wall reconstruction in unilateral orbital fractures. Fifteen patients (7 male and 8 female) with unilateral orbital fracture underwent orbital reconstruction with the help of intraoperative navigation system. The average age was 34.3 ± 9.5 years. All patients underwent spiral CT scanning preoperatively, and the CT data was imported to the BrainLab navigation system (Germany, BrainLab company). The orbit of the intact side was mirrored to the opposite side as the reference for pre-operative planning. The titanium mesh was mounted on the resin template made by rapid prototyping machine based on the mirrored CT data. When the injury was limited, the hydroxyapatite sheet was used for the orbital wall reconstruction. During the operation, the real-time navigation helped to ensure precise placement. The re-establishing result was assessed based on the postoperative CT data with the following four variables: the volumetric difference between the bilateral orbit, the volume of the herniated soft tissue, the global projection and the discrepancy between the simulated and the achieved position of the reconstructed orbital wall. The reconstructive discrepancy was measured only in the titanium plate grafting cases. There were no serious complications such as infection, graft rejection and optic nerve injury in any case. Preoperatively, the average degree of enophthalmos was (3.5 ± 1.6) mm, the average volumetric difference between the injured and the unaffected orbit was (4.5 ± 1.8) ml, and the average volume of the herniated orbital soft tissue was (2.1 ± 0.7) ml. Postoperatively, the three values were respectively reduced to (1.3 ± 0.6) mm, (1.8 ± 0.9) ml and (0.7 ± 0.3) ml. The discrepancy of the medial and inferior wall were (2.5 ± 0.6) mm and (2.1 ± 0.4) mm. The intraoperative use of navigation system for the orbital wall reconstruction in unilateral orbital fractures can provide reliable accuracy and

    To analyze the cosmetic and functional results of a large series of patients with unilateral congenital ptosis without spontaneous compensatory ipsilateral frontalis hyperaction who underwent supramaximal levator resection (SMLPSr). A multicenter retrospective review of 35 children (14 girls and 21 boys) of mean age 5.5±3.6 SD years with unilateral congenital ptosis who underwent surgery in 3 different countries: Italy, n=8; Argentina, n=11; and Brazil, n=16. Preoperative evaluation included measurements of upper eyelid margin reflex distance (MRD1) and levator palpebrae superioris muscle excursion, assessment of frontalis hyperaction, and ocular motility examination. At least 6 months postoperatively, photographs were used to measure the upper eyelid contour of OU. The spontaneous blinking amplitude and downward eyelid saccades of OU were quantified in a subset of 14 patients. Quantitative comparison among the 3 centers was performed with nonparametric 1-way analysis of variance (Kruskal-Wallis). Paired t tests were used to compare the pre- and postoperative measurements, and p valueMRD1 of the operated eyes increased from 0.5±1.1 SD mm to 3.4±0.84 SD mm (t=15.9; p<0.000001), consequently the eyelid positional asymmetry decreased from 3.1±1.21 mm to 0.1±0.86 SD mm (t=16.5; p≤0.000001). Twenty-nine percent of eyelids had mild contour abnormalities and 31.4% showed some degree of lash ptosis. Spontaneous blinks were abnormal in 93% of the cases (eyelids). The amplitude of the abnormal blinks ranged from 12.9% to 65.4% (mean=37.1%) of the contralateral eyelids. Downward eyelid saccades were reduced in 79% of the eyelids. The amplitudes the saccades ranged from 2.2% to 84.6% (mean=54.8%). In unilateral congenital ptosis, SMLPSr effectively reduces the positional asymmetry between eyelids. Mild contour abnormalities and lash ptosis are the main complications of the surgery. Postoperatively, spontaneous blinks and downward saccades were reduced in most eyelids

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

    Full Text Available 【Abstract】Objective: To investigate the clinical features and treatment strategy of dissymmetric bilateral frontal contusion, and to summarize our experience in treat-ing these patients by minimally invasive surgery. Methods: Over the past 3 years, we have treated a total of 31 patients with dissymmetric bilateral frontal contusion using endoscopy-assisted unilateral cerebral falx incision. Other 30 patients treated by routine bilateral approaches within the same period were taken as control. Results: Seventeen cases (54.8% in the unilateral operation group survived and were in good condition, 8 (25.8% had moderate disability, 4 (12.9% had severe disability, 1 (3.2% was in vegetative state, and 1 (3.2% died. Compared with the control group, the Glasgow Out-come Scale score was not significantly different in the uni-lateral operation group, but the operation time, blood trans-fusion volume, the length of hospital stay, the incidences of mental disorder and olfactory nerve injury were greatly reduced in the unilateral operation group. Conclusions: Endoscopy-assisted unilateral cerebral falx incision can shorten the operation time, reduce surgical trauma and complications in treatment of patients with dis-symmetric bilateral frontal contusion. It can obviously di-minish the chance of delayed intracerebral hematoma and subsequently minimize the incidences of subfalcial and centrencephalic herniation.

    The purpose of this cross-sectional study was to evaluate the effect of unstable and unilateral resistance exercises on trunk muscle activation. Eleven subjects (6 men and 5 women) between 20 and 45 years of age participated. Six trunk exercises, as well as unilateral and bilateral shoulder and chest presses against resistance, were performed on stable (bench) and unstable (Swiss ball) bases. Electromyographic activity of the upper lumbar, lumbosacral erector spinae, and lower-abdominal muscles were monitored. Instability generated greater activation of the lower-abdominal stabilizer musculature (27.9%) with the trunk exercises and all trunk stabilizers (37.7-54.3%) with the chest press. There was no effect of instability on the shoulder press. Unilateral shoulder press produced greater activation of the back stabilizers, and unilateral chest press resulted in higher activation of all trunk stabilizers, when compared with bilateral presses. Regardless of stability, the superman exercise was the most effective trunk-stabilizer exercise for back-stabilizer activation, whereas the side bridge was the optimal exercise for lower-abdominal muscle activation. Thus, the most effective means for trunk strengthening should involve back or abdominal exercises with unstable bases. Furthermore, trunk strengthening can also occur when performing resistance exercises for the limbs, if the exercises are performed unilaterally.

    Consideration of the causes of unilateral paranasal sinusitis, which frequently occurs in routine medical care and is often associated with odontogenic infection. Retrospective data analysis. A review of the charts of all 190 patients treated for unilateral paranasal sinusitis at our department between 2005 and 2012 was carried out. All patients were diagnosed based on clinical signs, symptoms, and imaging findings, including computed tomography (CT), orthopantomography (OP), and other modalities. Patients were classified in three groups: patients with odontogenic infection involvement (Group A); patients without odontogenic infection involvement (Group B); and patients with inconclusive odontogenic infection involvement (Group C). The most common cause of unilateral paranasal sinusitis was odontogenic infection, as seen in 138 cases (72.6%), followed by chronic inflammation in 43 cases (22.6%). Among patients diagnosed with odontogenic infection, one patient was also diagnosed with coexistent polyps and mycosis. Based on CT, OP, EPT, and oral examination, final distribution was 138 patients (72.6%) in Group A, 32 (16.8%) in Group B, and 20 (10.5%) in Group C. Odontogenic infection involvement was implicated in approximately 70% cases of unilateral paranasal sinusitis. Odontogenic maxillary sinusitis can be difficult to diagnose, and consideration of imaging performed under various conditions is recommended. In order to determine the most appropriate treatment for unilateral paranasal sinusitis, whether such treatment will be surgery, dental treatment, conservative therapy, or other treatments, collaboration between concerned doctors is essential.

    The authors retrospectively reviewed 33 cases of fracture involving the anterior colliculus of the medial malleolus to examine clinical results of operative treatment for these fractures. Although this injury appears innocuous, it can be difficult to obtain stable fixation of the fragment intraoperatively, and painful nonunion can result. A simple reduction maneuver and method of tension band fixation are described.

    Full Text Available Antiphospholipid syndrome (APS with pleural effusion is extremely rare. A 75-year-old man was admitted to our hospital for spreading erythema on his trunk and extremities, as well as dyspnea. One year before admission, he had visited us with a 1-year history of erythema and purpura on his legs and occasional fever. Given the diagnosis of APS, we initiated a combination therapy of aspirin and warfarin, but the skin lesions had gradually worsened. A biopsy specimen revealed marked thrombosis in the dermal and subcutaneous small vessels. In addition, chest X-ray and computed tomography demonstrated a large pleural effusion in the left lung. He underwent repeated drainage of the pleural effusion but the effusion recurred. We added oral prednisolone 30 mg daily to his prior anticoagulant therapy. The skin lesions and pleural effusion rapidly improved and disappeared without any complication. Corticosteroids might be a choice of treatment for intractable pleural effusion in APS patients.

    Traumatic C1-2 dislocation associated with contiguous or noncontiguous cervical spine injury is rare. Moreover, there have been no reports describing traumatic C1-2 dislocation associated with multiple contiguous and noncontiguous cervical injuries. The authors present a case of a 20-year-old male with painful limitation of motion of the neck. This complex cervical injury occurred due to hyperextension of the head in a rotated position. The patient complained of neck pain that radiated to the left shoulder and arm, but he did not exhibit any neurological abnormalities. The diagnosis of the patients was traumatic C1-2 posterolateral dislocation associated with type II dens fracture (Anderson and D'Alonzo classification), type II injury of the transverse atlantal ligament (Dickman classification), and unilateral facet fracture with subluxation of C6-7. The C1-2 posterolateral dislocation with type II dens fracture was successfully reduced by skull traction. The patient underwent anterior discectomy, open reduction, and fusion with plate fixation of C6-7 followed by posterior segmental fixation and fusion of C1-2. At his postoperative 1-year follow-up, solid fusion was noted with improvement of clinical symptoms. This is the first report of traumatic C1-2 posterolateral dislocation associated with multiple C2 injuries and noncontiguous subaxial cervical injury. A high index of suspicion and careful evaluation of entire cervical spine should be considered as the key to the proper diagnosis and treatment of traumatic C1-2 dislocation associated with contiguous and noncontiguous cervical injuries.

    We identified the presence of deformities in the affected pelvis of unilateral Crowe type IV DDH patients, and if present, whether the teardrop and ischial lines were parallel with the sacral base line. We also verified whether the sacral base line provided a better pelvic landmark than the teardrop line for determining leg length inequality (LLI). After leveling the pelvis by using a block to lift the short leg, standard anterior-posterior full-length radiography was performed on 10 patients and 10 healthy volunteers as controls. The ratio of pelvic heights on each side of the pelvis, the angles formed by the sacral base line and the other 2 lines between 2 groups were measured. LLI were measured by sacral base line and teardrop line respectively. The ratio between the pelvic heights was lower in the patient group than in the control group (0.95 versus 0.99). The angles between the teardrop and ischial lines and the sacral base line in the patient group were both greater than in the control group (6.08° versus 0.92° and 7.13° versus 0.97°). LLI measured from the sacral base line was larger than from the teardrop line in the patient group (5.55 cm versus 4.36 cm). There was pelvic asymmetry and the sacral base line was not parallel with the other 2 lines in unilateral Crowe type IV DDH. The leveled sacral base line was perpendicular to the longitudinal axis of the body, and may be a better choice for accurate LLI measurement in this situation.

    The aim of this article is to analyze dental abnormalities in unilateral cleft lip and palate patients by focusing on the role of the secondary alveolar bone graft (SABG) surgery and its outcomes on canine eruption/inclusion. A sample of 24 patients with unilateral cleft lip and palate were selected.Dental anomalies, canine eruption based on the existence of supernumeraries, agenesis elements, inclination of the major canine axis before and after surgery, distance from the occlusal plane before and after surgery, and sector classification were analyzed. Out of the 24 patients, 87.5% presented a canine spontaneously erupted in the dental arch while 12.5% needed surgical-orthodontic traction.There is also no proof that inclination of the canine significantly influenced the eruption before (P = 0.5889) and after (P = 0.4029) surgery. Also, there is no any correlation between the 2 sides (P = 0.1257).The SABG surgery showed a significant correlation with canine eruption (P = 0.009242); moreover, SABG shows a positive relationship with the radicular development of the canine (P = 0.005163).Lateral incisive (P = 0.8493) and second premolar agenesis (P = 1) are not statistically correlated with the eruption of the canine. This does not happen with supernumerary elements that are correlated with the surgical-orthodontic traction (P = 0.0004464). Agenesis does not play any role in the process of canine eruption while supernumeraries do. There is no relationship between the inclination and eruption of the canine.The SABG surgery has a key role because it contributes to create an appropriate support for the erupting canine, the nasal base and the anterior maxilla.

    The aim of the study was to uncover mechanisms of central compensation of vestibular function at brainstem, cerebellar, and cortical levels in patients with acute unilateral midbrain infarctions presenting with an acute vestibular tone imbalance. Eight out of 17 patients with unilateral midbrain infarctions were selected on the basis of signs of a vestibular tone imbalance, e.g., graviceptive (tilts of perceived verticality) and oculomotor dysfunction (skew deviation, ocular torsion) in F18-fluordeoxyglucose (FDG)-PET at two time points: A) in the acute stage, and B) after recovery 6 months later. Lesion-behavior mapping analyses with MRI verified the exact structural lesion sites. Group subtraction analyses and comparisons with healthy controls were performed with Statistic Parametric Mapping for the PET data. A comparison of PET A of acute-stage patients with that of healthy controls showed increases in glucose metabolism in the cerebellum, motion-sensitive visual cortex areas, and inferior temporal lobe, but none in vestibular cortex areas. At the supratentorial level bilateral signal decreases dominated in the thalamus, frontal eye fields, and anterior cingulum. These decreases persisted after clinical recovery in contrast to the increases. The transient activations can be attributed to ocular motor and postural recovery (cerebellum) and sensory substitution of vestibular function for motion perception (visual cortex). The persisting deactivation in the thalamic nuclei and frontal eye fields allows alternative functional interpretations of the thalamic nuclei: either a disconnection of ascending sensory input occurs or there is a functional mismatch between expected and actual vestibular activity. Our data support the view that both thalami operate separately for each hemisphere but receive vestibular input from ipsilateral and contralateral midbrain integration centers. Normally they have gatekeeper functions for multisensory input to the cortex and automatic

    Full Text Available Objetivo: apresentar os aspectos clínicos, diagnósticos e terapêuticos de pacientes portadores de válvula da uretra anterior. Descrição: em dois neonatos, o diagnóstico presuntivo de patologia obstrutiva do trato urinário foi sugerido pela ultra-sonografia realizada no período pré-natal, confirmando-se o diagnóstico de válvula de uretra anterior pela avaliação pós-natal. Os pacientes foram submetidos a tratamento cirúrgico paliativo, com vesicostomia temporária e, posteriormente, definitivo, pela fulguração endoscópica das válvulas. Ambos evoluíram com função renal normal. Comentários: a válvula da uretra anterior é anomalia rara que deve ser considerada em meninos com quadro radiológico pré-natal sugestivo de obstrução infravesical, secundariamente à hipótese mais comum de válvula da uretra posterior. Ressaltamos a utilização da vesicostomia como derivação urinária temporária nestes casos, prevenindo potenciais complicações pela manipulação da uretra do recém-nascido.Objective: to discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. Description: signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was performed in both patients. Later, the valves were fulgurated using an endoscopic procedure. During the follow-up period both patients presented normal renal function. Comments: anterior urethral valves are a rare form of urethral anomaly that must be ruled out in boys with pre-natal ultrasound indicating infravesical obstruction. Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra.

    The authors analyzed the cosmetic and functional results of a series of patients with unilateral congenital ptosis who underwent levator resection, to compare the outcome of surgery according to the age of intervention, and to evaluate the chance of ptosis recurrence in different age groups. Analysis of the clinical charts of 44 patients who underwent a unilateral levator muscle resection under the care of one surgeon from February 2000 to March 2012 was performed. Age at the time of surgery ranged from 2.1 to 12 years. The study population was divided into different groups according to the age of surgery. Preoperative evaluation included measurements of upper eyelid margin reflex distance (MRD1), levator function, frontalis function, and complete extraocular motility examination. This study adheres to the principles outlined in the Declaration of Helsinki. The patients' follow-up ranged between 2 and 12 years. The outcome of surgery was more satisfactory (MRD1 increase: p < 0.002) and the increase of levator function was better (p < 0.0001) when surgery was performed in children aged 2 to 4 years. No ptosis recurrence was observed in children aged 2 to 4 years, as opposed to 6 (22%) children of other groups (p = 0.067). Unilateral levator resection effectively reduces the asymmetry between eyelids. The age of the operation appears to influence the outcome of surgery, as in this series cosmetic and functional results are better and the rate of ptosis recurrence is lower if the child is operated on before the age of 4 years.

    The present study aimed to evaluate the potential correlations between objective measurements of nasal function and self-assessed nasal symptoms or clinical findings at nasal examination among adults treated for unilateral cleft lip and palate (UCLP), respectively. All UCLP patients born between 1960 and 1987 (n = 109) treated at a tertiary referring center were invited. Participation rate was 76% (n = 83) at a mean of 37 years after the initial surgery. All participants completed the same study protocol including acoustic rhinometry (AR), rhinomanometry (RM), anterior rhinoscopy, and questionnaires regarding self-experienced nasal symptoms. A reduced volume of the anterior nasal cavity on the operated side (measured by AR) correlated to an expressed wish by the patient to change the function of the nose. A similar correlation was seen for the minimal cross-sectional area of anterior nasal cavity on the operated side. Furthermore, correlations were found between smaller volume and area of nasal cavity and a greater frequency of nasal obstruction. No further correlations were found. Objective measurements partly correlate to the clinical picture among adults treated for UCLP. However, these need to be combined with findings at clinical examination and patient self-assessment to represent the complete clinical picture.

    Full Text Available Gynecomastia is defined as the excessive development of breast tissue in males, which can occur as unilateral or bilateral. Although the overall prevalence of gynecomastia is 40%-65%, the prepubertal unilateral gynecomastia in the absence of endocrine abnormalities is unusual, with only a few case reports in literature. Idiopathic gynecomastia in prepuberty is benign but a diagnosis of exclusion. We here report two cases of healthy prepubertal boys aged 8.8 and 9.6 years old, respectively, presented with painful palpable mass in their unilateral breast. Breast tissue with glandular proliferation was confirmed on ultrasonography. Serum levels of estradiol, testosterone, and other laboratory findings were within normal range. They seem to have the prepubertal idiopathic gynecomastia but further follow-up to see their progression is needed.

  16. Evaluation and management of unilateral ptosis and avoiding contralateral ptosis.

    2010-01-01

    Treating unilateral ptosis can be challenging and a proper preoperative evaluation may help prevent unexpected outcomes on the contralateral lid. Preoperative evaluation should include testing for Hering's law, which remains useful in understanding the phenomenon of induced contralateral eyelid retraction in the context of ptosis. Approximately 10% to 20% of patients with unilateral ptosis have some degree of induced retraction on clinical evaluation in the contralateral lid. When there is a positive Hering's test on preoperative examination, the surgeon should consider a bilateral ptosis procedure. The surgical approach to unilateral ptosis depends on the severity of the ptosis and its etiology, and the surgeon should be aware of which procedure is most likely to provide the best outcome in selected instances.

    Unilateral perinephric pseudocyst of undetermined origin was diagnosed in a 131/2 year old dog with a history of recurrent urinary tract infections. A presumptive diagnosis of pseudocyst was based on radiographic and sonographic findings. In survey radiographs, asymmetrical unilateral renomegaly was seen. The mass was anechoic. There was absence of opacification of the mass during excretory urography. A celiotomy was performed for removal of the perinephric mass, and histologic review of this structure confirmed it to be a pseudocyst. Perinephric accumulation of fluid is a rare condition in domestic animals. Seven examples of perinephric pseudocysts have been previously reported in the cat. Predominant clinical findings include progressive abdominal distension and nonspecific signs of renal disease. The presence of unilateral or bilateral renomegaly is a characteristic radiographic feature. This clinical report describes the first case of perinephric pseudocyst diagnosed in the dog

    Although the diagnostic workup and management regimens for many of the common fetal thoracic lesions have been well described, the understanding of pulmonary agenesis is more limited. A better understanding of the published reports of this condition is essential to provide proper care for these complicated pregnancies. The aims of this study were to provide a better understanding of the difficulties in the diagnosis and management of fetal thoracic lesions and to consolidate what is known about unilateral pulmonary agenesis. We performed a review of the English medical literature covering the last 20 years (1993-2013) in PubMed, MEDLINE, and MD Consult using search terms pulmonary agenesis, pulmonary aplasia, unilateral pulmonary agenesis, unilateral pulmonary aplasia, lung agenesis, lung aplasia, unilateral lung agenesis, and unilateral lung aplasia. Prenatal diagnosis of pulmonary agenesis and other fetal thoracic lesions can be particularly challenging given that many anomalies have similar appearance on ultrasound. Fetal magnetic resonance imaging has been used in several of the reported cases to clarify the diagnosis. Once confirmed, there are several important prognostic factors to consider in the management of unilateral pulmonary agenesis. Poor prognostic factors include right-sided agenesis, the presence of genetic abnormalities, and other associated congenital anomalies. Fetal magnetic resonance imaging can be a useful imaging modality when the diagnosis is unclear after ultrasound imaging. The management of cases with a poor prognosis should be guided by the nature of the associated anomalies. Cases of isolated pulmonary agenesis have an overall good prognosis and can be managed conservatively during pregnancy, with consideration of delivery at a tertiary care facility in case postnatal respiratory issues arise.

    Full Text Available Research from Shogan (2007 and Lim (2008 on the executive branch proposes that the American presidency has adopted an anti-intellectual approach to leadership, such that there is a concerted rejection of thoughtful political discourse from the president. This has been reflected by what appears to be a relative decline in both the linguistic and substantive complexity of presidential rhetoric. Shogan’s (2007 work, while focused on examining whether Republicans are more apt to employ anti-intellectual leadership than Democrats, raises an additional topic worthy of empirical examination: the potential relationship between anti-intellectual leadership and unilateral action from the president. If anti-intellectual leadership is a defiant form of leadership that opts to publicly demonstrate the rejection of external expertise, the usage of anti-intellectual rhetoric from the president might be able to predict the usage of unilateral action. On the other hand, anti-intellectual rhetoric might be used as a straightforward and quick means to explain unilateral action, such that change in the level of unilateral action can predict the usage of simplistic rhetoric. Unfortunately, no one has yet to empirically test whether rhetorical simplicity predicts unilateral action, unilateral action predicts rhetorical simplicity, or there is a multi-directional relationship present. This project makes an initial attempt to remedy this gap in the literature. The project contrasts the monthly average simplicity level of the presidential weekly public address with the monthly number of executive orders emanating from the executive branch, using information spanning between February 1993 and May 2015. The initial findings from the vector autoregression and moving average representation analyses suggest that prior change in rhetorical simplicity predicts the usage of executive orders, and that an increase in rhetorical simplicity helps produce an increase in the number

    Full Text Available Purpose: To compare the anterior segment parameters in photopic and scotopic conditions using anterior segment optical coherence tomography (AS OCT in Indian eyes. Materials and Methods: One hundred eyes of 100 normal subjects of both sexes, aged 19 to 76 years, underwent anterior segment evaluation by AS OCT (VisanteTM OCT. Central corneal thickness (CCT, central anterior chamber depth (ACD, pupil diameter (PD and the temporal and nasal peripheral irido-corneal angles were assessed in photopic and scotopic conditions. These anterior segment parameters were stratified for age, sex and refractive error. Results: Mean values of the parameters measured in photopic and scotopic conditions respectively were as follows: ACD (mm 2.88 ± 0.32, 2.89 ± 0.32 (P = 0.10; nasal angle (degrees 28.80 ± 5.91, 22.28 ± 7.50 (P < 0.001; temporal angle (degrees 29.95 ± 6.74, 22.82 ± 8.43 (P < 0.001; pupil diameter (mm 4.08 ± 0.91, 4.68 ± 0.92 (P < 0.001; CCT (µm 519 ± 33.88, 519 ± 33.88. Conclusions: There was no significant difference in the ACD in photopic and scotopic conditions. While the nasal and temporal angles showed a significant decrease, the pupil diameter showed a significant increase in scotopic conditions. Mean central ACD decreased with age and was shallower in females than in males. It was highest in myopes and lowest in hypermetropes. CCT was not influenced by photopic and scotopic conditions.

    The purpose of this study is to describe our policy in selecting different types of anaesthesia and anterior tension-free techniques for the repair of recurrent inguinal hernias previously treated by anterior approach and to evaluate early and late outcomes. The medical records of 111 patients who underwent recurrent inguinal hernia repair by anterior approach in the period 2000-2013 were reviewed. Fifty patients (45 %) were over 70 years old and 63 (56.7 %) had one or more co-morbidities. Hernias with large defects were the most frequently observed (59.5 %), and no-mesh techniques were the most frequent failed repair (75.7 %). Different anterior tension-free techniques and types of anaesthesia were used, depending on hernia and patient characteristics. Seventy-three patients (65.8 %) were operated on an outpatient basis. Mean follow-up period was 89 months (range 10-183). No perioperative deaths, medical events, or visceral injuries were recorded. Early postoperative complications occurred in 11 patients: 4 haematomas (3.6 %), 5 seromas (4.5 %), 1 superficial wound infection (0.9 %) and 1 ischemic orchitis (0.9 %). Late complications consisted in 3 cases of chronic moderate pain (3.2 %) and 2 re-recurrences (2.1 %). Recurrent inguinal hernia previously treated by open anterior technique can be repaired using the same approach, often on an outpatient basis, with a low rate of recurrence and postoperative complications. To be safe and effective, the repair should be performed by appropriately trained surgeons, well versed in the use of different types of anaesthesia and surgical techniques depending on patient and hernia characteristics.

    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.

    Cervical spondylolysis, with or without spondylolisthesis, is a rare condition defined as a corticated cleft between the superior and inferior articular facets of the articular pillar. The defect occurs predominantly at C6, and is usually bilateral in up to two-thirds of cases. Multilevel involvement is uncommon, however, to date, no case of two consecutive levels of unilateral cervical spondylolysis on opposite sides has been reported. Here, we report a rare case of a patient affected by two consecutive levels of unilateral cervical spondylolysis at C5 and C6 on opposite sides in a 19-year-old male complaining of neck pain.

    The bioelectric activity of muscles (flexors and extensors of the forelimbs and hindlimbs) during cold shivering after unilateral destruction of the vestibular apparatus. It was found, that unilateral delabyrinthing produces bilateral facilitation of cold shivering in the flexor extremities more pronounced on the ipsilateral side. In the extensor muscles there was an absence of bioelectric activity both before and after delabyrinthing. Enhancement of cold shivering in the flexor extremities following intervention was evidently conditioned by removal of the inhibiting effect of the vestibulary apparatus on the function of special centers.

    This study aimed to describe a new titanium thyroplasty implant that can be adjusted with a screw. Six Beagle dogs were randomly divided into experimental and control groups (n = 3). The titanium screw was implanted in the experimental group after the left recurrent laryngeal nerve was cut off under general anaesthesia. This procedure caused arytenoid cartilage internal shift, allowing the vocal cord to locate at the median and the glottis to close during phonation. No other operation was conducted in the control group. Each group, respectively, underwent video laryngoscopy, CT scan and histopathology before and after operation. After 4 months of follow-up, the video laryngoscopy results showed that the left arytenoid cartilage in the experimental group underwent internal adduct and shift, whereas the left vocal cords in the control group located at the paramedian position and exhibited fissure during phonation. CT scan results showed that the adjustable titanium screw was in proper position. Postoperative pathological examination showed that, in addition to early local inflammation, the laryngeal muscle may atrophy. The adjustable titanium screw requires a simple operation and can be significantly adjusted. The effect of the operation can be immediately observed without rejection. Therefore, this method is an efficient treatment for unilateral vocal cord paralysis.

    2015-01-01

    Full Text Available Pulmonary arteriovenous Malformations (PAVMs are a rare vascular alteration characterized by abnormal communications between the pulmonary arteries and veins resulting in an extracardiac right-to-left (R-L shunt. The majority of PAVMs are associated with an autosomal dominant vascular disorder also known as Osler-Weber- Rendu Syndrome. PAVMs appearance can be both single and multiple. Clinical manifestations include hypoxemia, dyspnea cyanosis, hemoptysis and cerebrovascular ischemic events or abscesses. We report a case of an 18 year old female with severe respiratory failure caused by a relapse of multiple unilateral pulmonary arterovenous fistula. Symptoms at admission include dyspnea, cyanosis and clubbing. The patient underwent pulmonary angio-TC scan, brain CT and echocardiography. The thoracic angio-CT scan showed the presence of PAVMs of RUL and RLL; a marked increase of right bronchial artery caliber and its branches with an aneurismatic dilatation was also observed. The patient underwent percutaneous transcatheter embolization using Amplatzer Vascular Plug IV; a relevant clinical and functional improvement was subsequently recorded. Embolization is effective in the treatment of relapsing PAVMS.

    After an anterior cruciate ligament (ACL) injury, the uninjured contralateral lower limb may become weakened because of neuromuscular changes, proprioceptive deficits, and disuse of the limb; this weakness predisposes the limb to ACL injury. However, no results have been reported regarding weakness in the contralateral limb after ACL injury. Muscle strength and functional status of the contralateral lower limb are reduced after unilateral ACL injury. Cohort study; Level of evidence, 3. The ACL group consisted of 75 patients who underwent primary unilateral ACL reconstruction and were followed at 3, 6, 12, and 24 months postoperatively. A group of 75 healthy individuals (controls) were matched one-to-one with the ACL group for age, sex, body mass index, and initial Tegner activity level. The side that was evaluated in each control subject corresponded to the injured limb in the matched ACL subject. Isokinetic muscle strength, including extension peak torque per body weight (EPT) and flexion peak torque per body weight (FPT), was evaluated at angular velocities of 60 and 180 deg/s. Patients were also evaluated by single-legged hop test. Compared with the EPT at 60 deg/s in the control group (290.9 ± 40.1 N · m/kg), the value in the ACL group 24-month follow-up (276.6 ± 42.8 N · m/kg) as well as other follow-up times was significantly lower (P lower than the control group at 3-month follow-up but were restored to normal levels at final follow-up. Results from the single-legged hop test demonstrated that the ACL group performed at a significantly lower level than the control group at 24-month follow-up (158.4 ± 25.3 vs 176.3 ± 24.7 cm; P strength and functional status of the contralateral limb were reduced, even at 24 months after ACL reconstruction. However, both measurements improved significantly as the follow-up time progressed. In contrast, flexion muscle strength was restored to normal levels. Therefore, care should be taken to restore muscle strength and

Este trabalho tem como objetivo relatar um caso de telangiectasia nevoide unilateral adquirida em homem jovem, sem comorbidades, alterações clínicas e/ou laboratoriais sugestivas de hiperestrogenismo.Unilateral nevoid telangiectasia is a rare vascular dermatosis, characterized by areas of superficial telangiectases distributed in a linear unilateral pattern. It was described in 1899 by Zeisler and Blascko. Several theories where developed in order to explain its etiopathogenesis. The most widely accepted is the one which establishes its probable association with an increase in the estrogen levels. There are two types: congenital and acquired. The latter is associated with hepatopathies in male patients. The acquired form is rarely observed in healthy men, with a few cases reported in the medical literature, and its etiology is unknown. This study reports the case of a healthy young man with acquired unilateral nevoid telangiectasia, without any comorbidities, clinical and /or laboratory findings indicative of hyperestrogenism.

    Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondyloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the "activity" of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

    Gait analysis is a useful tool to evaluate the functional status of patients with anterior cruciate ligament injury. Pattern recognition methods can be used to automatically assess walking patterns and objectively support clinical decisions. This study aimed to test a pattern recognition system for analyzing kinematic gait patterns of recently anterior cruciate ligament injured patients and for evaluating the effects of a therapeutic treatment. Gait kinematics of seven male patients with an acute unilateral anterior cruciate ligament rupture and seven healthy males were recorded. A support vector machine was trained to distinguish the groups. Principal component analysis and recursive feature elimination were used to extract features from 3D marker trajectories. A Classifier Oriented Gait Score was defined as a measure of gait quality. Visualizations were used to allow functional interpretations of characteristic group differences. The injured group was evaluated by the system after a therapeutic treatment. The results were compared against a clinical rating of the patients' gait. Cross validation yielded 100% accuracy. After the treatment the score improved significantly (Pgait alterations in the early phase after anterior cruciate ligament injury can be detected automatically. The results of the automatic analysis are comparable with the clinical rating and support the validity of the system. The visualizations allow interpretations on discriminatory features and can facilitate the integration of the results into the diagnostic process. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Plyometric exercise is used during rehabilitation after anterior cruciate ligament (ACL) reconstruction to facilitate the return to sports participation. However, clinical outcomes have not been examined, and high loads on the lower extremity could be detrimental to knee articular cartilage. To compare the immediate effect of low- and high-intensity plyometric exercise during rehabilitation after ACL reconstruction on knee function, articular cartilage metabolism, and other clinically relevant measures. Randomized controlled trial; Level of evidence, 2. Twenty-four patients who underwent unilateral ACL reconstruction (mean, 14.3 weeks after surgery; range, 12.1-17.7 weeks) were assigned to 8 weeks (16 visits) of low- or high-intensity plyometric exercise consisting of running, jumping, and agility activities. Groups were distinguished by the expected magnitude of vertical ground-reaction forces. Testing was conducted before and after the intervention. Primary outcomes were self-reported knee function (International Knee Documentation Committee [IKDC] subjective knee form) and a biomarker of articular cartilage degradation (urine concentrations of crosslinked C-telopeptide fragments of type II collagen [uCTX-II]). Secondary outcomes included additional biomarkers of articular cartilage metabolism (urinary concentrations of the neoepitope of type II collagen cleavage at the C-terminal three-quarter-length fragment [uC2C], serum concentrations of the C-terminal propeptide of newly formed type II collagen [sCPII]) and inflammation (tumor necrosis factor-α), functional performance (maximal vertical jump and single-legged hop), knee impairments (anterior knee laxity, average knee pain intensity, normalized quadriceps strength, quadriceps symmetry index), and psychosocial status (kinesiophobia, knee activity self-efficacy, pain catastrophizing).

    Full Text Available Conservative therapy is often the first-line treatment for many symptoms of various disease processes, including pain. Nevertheless, if pharmacological or medical management fails for those patients with severe and chronic pain, a surgical strategy may be a reasonable option. First performed for psychiatric disorders, cingulotomy now has been recognized as a viable option for the management of pain. The authors review the literature on anterior cingulotomy for intractable pain to provide guidelines for management and expected outcomes.

  3. Anterior shoulder dislocations in sports.

    Aronen, J G

    1986-01-01

    Anterior shoulder dislocations, primary and recurrent, are among the most disabling injuries to the shoulder that can plague the athlete. The diagnosis is easily made by the following: the physical appearance of the shoulder; loss of capability by the athlete to internally and externally rotate the shoulder with the elbow at his side; by evaluating the mechanism of injury; and x-rays. Anterior shoulder dislocations should be reduced as soon as possible after diagnosis, to minimise the stretching effect on the neurovascular structures while the humeral head is dislocated. The reduction is not done to allow the athlete to return immediately to sport. Use of a simple traction method in the first 10 to 15 minutes following the injury will result in a successful reduction in the vast majority of dislocations. Reduction of the humeral head can be confirmed by the athlete regaining the capability to internally and externally rotate his shoulder with his elbow at his side. Following reduction, the athlete should begin a treatment regimen which includes a restrengthening programme emphasising the muscles of internal rotation and adduction plus rigid restrictions of activities until the goals of the rehabilitation programme are satisfied. The author's experience with this treatment regimen with athletes at the United States Naval Academy, has shown a decrease of the recurrence rate of primary anterior shoulder dislocations to 25% versus the 80% recurrence rate we have become familiar with from studies done which did not stress specific rehabilitation programmes. The athlete should also be instructed in a self-performed traction method for reduction should a redislocation occur, to minimise the stretching effect on the neurovascular structures and allow relief from discomfort. Surgery for primary and recurrent anterior dislocations should only be considered when the athlete fails to achieve the desired goals after participating in a specific, progressive, adequate

Anterior cruciate ligament repair is a commonly performed orthopaedic procedure. This paper examines the concordance between MR imaging and arthroscopic findings. Methods Between February, 1996 and February, 1998, 48 patients who underwent magnetic resonance (MR imaging of the knee were reported to have complete tears of the anterior cruciate ligament (ACL. Of the 48 patients, 36 were male, and 12 female. The average age was 27 years (range: 15 to 45. Operative reconstruction using a patellar bone-tendon-bone autograft was arranged for each patient, and an arthroscopic examination was performed to confirm the diagnosis immediately prior to reconstructive surgery. Results In 16 of the 48 patients, reconstructive surgery was cancelled when incomplete lesions were noted during arthroscopy, making reconstructive surgery unnecessary. The remaining 32 patients were found to have complete tears of the ACL, and therefore underwent reconstructive surgery. Using arthroscopy as an independent, reliable reference standard for ACL tear diagnosis, the reliability of MR imaging was evaluated. The true positive rate for complete ACL tear diagnosis with MR imaging was 67%, making the possibility of a false-positive report of "complete ACL tear" inevitable with MR imaging. Conclusions Since conservative treatment is sufficient for incomplete ACL tears, the decision to undertake ACL reconstruction should not be based on MR findings alone.

    The anterior cruciate ligament transection (ACLT) rabbit osteoarthritis (OA) model confers permanent knee instability and induces joint degeneration. The degeneration process is complex, but includes chondrocyte apoptosis and OA-like loss of cartilage integrity. Previously, we reported that activation of a volume-sensitive Cl(-) current (ICl,vol) can mediate cell shrinkage and apoptosis in rabbit articular chondrocytes. Our objective was therefore to investigate whether ICl,vol was activated in the early stages of the rabbit ACLT OA model. Adult Rabbits underwent unilateral ACLT and contralateral arthrotomy (sham) surgery. Rabbits were euthanized at 2 or 4 weeks. Samples were analyzed histologically and with assays of cell volume, apoptosis and electrophysiological characterization of ICl,vol. At 2 and 4 weeks post ACLT cartilage appeared histologically normal, nevertheless cell swelling and caspase 3/7 activity were both significantly increased compared to sham controls. In cell-volume experiments, exposure of chondrocytes to hypotonic solution led to a greater increase in cell size in ACLT compared to controls. Caspase-3/7 activity, an indicator of apoptosis, was elevated in both ACLT 2wk and 4wk. Whole-cell currents were recorded with patch clamp of chondrocytes in iso-osmotic and hypo-osmotic external solutions under conditions where Na(+), K(+) and Ca(2+) currents were minimized. ACLT treatment resulted in a large increase in hypotonic-activated chloride conductance. Changes in chondrocyte ion channels take place prior to the onset of apparent cartilage loss in the ACLT rabbit model of OA. Further studies are needed to investigate if pharmacological inhibition of ICl,vol decreases progression of OA in animal models. Copyright © 2016 The Authors. Published by Elsevier Ltd..

    Computed tomography (CT) is used to assess for fracture after knee trauma, but identification of ligamentous injuries may also be beneficial. Our purpose is to assess the potential of dual-energy computed tomography (DECT) for the detection of complete anterior cruciate ligament (ACL) disruption. Sixteen patients with unilateral traumatic ACL disruption (average of 58 days following trauma) confirmed by MRI, and 11 control patients without trauma, underwent DECT of both knees. For each knee, axial, sagittal, and oblique sagittal images (with DECT bone removal, single-energy (SE) bone removal, and DECT tendon-specific color mapping) were reconstructed. Four musculoskeletal radiologists randomly evaluated the 324 DECT reconstructed series (54 knees with 6 displays) separately, to assess for ACL disruption using a five-point scale (1 = definitely not torn, to 5 = definitely torn). ROC analysis was used to compare performance across readers and displays. Sagittal oblique displays (mixed kV soft tissue, SE bone removal, and DECT bone removal) demonstrated higher areas under the curve for ACL disruption (AUC = 0.95, 0.93 and 0.95 respectively) without significant differences in performance between readers (p > 0.23). Inter-reader agreement was also better for these display methods (ICC range 0.62-0.69) compared with other techniques (ICC range 0.41-0.57). Mean sensitivity for ACL disruption was worst for DECT tendon-specific color map and axial images (24 % and 63 % respectively). DECT knee images with oblique sagittal reconstructions using either mixed kV or bone removal displays (either DECT or SE) depict ACL disruption in the subacute or chronic setting with reliable identification by musculoskeletal radiologists.

    Full Text Available Object. The implantation of interbody fusion cages allows for the restoration of disc height and the enlargement of the neuroforaminal space. The purpose of this study was to compare the extent of subsidence occurring after conventional cage placement compared to a novel wider cage placement technique. Methods. This study is a retrospective evaluation of radiographs of patients who underwent stand-alone single level anterior lumbar interbody fusion with lordotic titanium cages and rhBMP-2. Fifty-three patients were evaluated: 39 patients had wide cage placement (6 mm interdevice distance and 14 had narrow cage placement (2 mm interdevice distance. Anterior and posterior intervertebral disc space heights were measured post-operatively and at follow-up imaging. Results. The decrease in anterior intervertebral disc space height was 2.05 mm versus 3.92 mm (<.005 and 1.08 mm versus 3.06 mm in posterior disc space height for the wide cage placement and the narrow cage placement respectively. The proportion of patients with subsidence greater than 2 mm was 41.0% in the wide cage patients and 85.7% for the narrow cage patients (<.005. Conclusions. The wider cage placement significantly reduced the amount of subsidence while allowing for a greater exposed surface area for interbody fusion.

    Full Text Available Anterior chamber aspirate cultures were done for 66 patients who underwent either an uncomplicated intracapsular cataract extraction, extracapsular cataract extraction with posterior-chamber intraocular lens implantation, or phacoemulsification with posterior-chamber intraocular lens implantation. The aspirate was obtained at the time of wound closure. The aspirates were immediately transferred to the microbiology laboratory where one drop of the aspirate was placed on a glass slide for gram stain, and the remainder was unequally divided and inoculated into blood agar, chocolate agar and thioglycolate broth. The cultures were incubated at 37° C with 5% CO2 and held for 5 days. Of 66 patients 4 (6%, had smear-positive anterior chamber aspirates. None of the aspirates showed any growth on any of the 3 culture media used. None of the eyes in the study developed endophthalmitis. This study concludes that there is no contamination of the anterior chamber by viable bacteria after cataract surgery, irrespective of the mode of intervention.

    Objective: To evaluate the role of anterior cervical decompression and fixation with Caspar plating in cervical spine injury on neurological outcome. Study Design: A case series. Place and Duration of Study: Department of Neurosurgery, Jinnah Postgraduate Medical Centre, Karachi, from July 2008 to March 2011. Methodology: Thirty patients admitted with cervical spine injuries were inducted in the study. All cases were evaluated for their clinical features, level of injury and degree of neurological injury was assessed using Frankel grading. Pre and postoperative record with X-rays and MRI were maintained. Cervical traction was applied to patients with sub-luxation. All patients underwent anterior cervical decompression, fusion and Caspar plate fixation. The follow-up period was 6 months with clinical and radiological assessment. Results: Among 30 patients, 24 (80%) were males and 6 (20%) were females. Age ranged from 15 to 55 years. Causes of injury were road traffic accident (n = 20), fall (n = 8) and assault (n = 2). Commonest mode of injury was road traffic accident (66.6%). Postoperative follow-up showed that pain and neurological deficit were improved in 21 patients. There was no improvement in 7 patients, one patient deteriorated and one expired. All patients developed pain at donor site. Conclusion: Anterior decompression, fusion and fixation with Caspar plate is an effective method with good neurological and radiological outcome. However, it is associated with pain at donor site.

    To investigate the clinical efficacy of two different anterior cervical surgeries in treatment of multi-segmental cervical spondylosis. A total of 86 patients with multi-segmental cervical spondylosis were treated by anterior cervical surgery procedure. Among them, 62 and 24 cases were involved in three and four gap, respectively. Each patient underwent the surgery of long or segmented anterior cervical decompression and fixation. Preoperative and postoperative cervical curvature change, internal fixation stability, fusion rate and nerve function were evaluated. All patients were successfully completed the operation, segmented surgery showed better cervical lordosis recovery, but there were no significant difference between long and segmented anterior cervical surgery in blood loss and recovery of neurological function (P> 0.05). The segmented anterior cervical surgery has advantages in the treatment of multisegmental cervical spondylosis.

    Potentially valuable anterior cruciate ligament (ACL) injury prevention strategies are lengthy, limiting training success. Shorter protocols that achieve beneficial biomechanical adaptations may improve training effectiveness. This study examined whether core stability/balance and plyometric training can modify female landing biomechanics compared with the standard neuromuscular and no training models. Forty-three females had lower limb biomechanics analyzed during unilateral and bilateral landings immediately before and after a 6-week neuromuscular or no training programs. Sagittal and frontal plane hip and knee kinematics and kinetics were submitted to 3-way repeated-measures analyses of variance to test for the main and interaction effects of training group, landing type, and testing time. Greater peak knee flexion was evident in the standard neuromuscular group following training, during both bilateral (p = 0.027) and unilateral landings (p = 0.076 and d = 0.633). The plyometric group demonstrated reduced hip adduction (p = 0.010) and greater knee flexion (p = 0.065 and d = 0.564) during bilateral landings following training. The control group had significant reduction in peak stance knee abduction moment (p = 0.003) posttraining as compared with pretraining. The current outcomes suggest that significant biomechanical changes are possible by an isolated plyometric training component. The benefits, however, may not be evident across all landing types, seemingly limited to simplistic, bilateral landings. Integrated training protocols may still be the most effective training model, currently improving knee flexion posture during both bilateral and unilateral landings following training. Future prevention efforts should implement integrated training protocols that include plyometric exercises to reduce ACL injury risk of female athletes.

    A retrospective study. Anterior cervical fusion surgery is widely used procedure in cervical spondylosis. When considering the blood reinfusion strategies of cervical fusion surgery, the amount of blood loss is one of the key elements. We usually calculate the blood loss according to the surgical bleeding plus the postoperative drainage; however, this method ignores the possibility that there may be hidden blood loss (HBL). We performed a retrospective study to determine the risk factors for HBL in patients who underwent anterior cervical fusion surgery for degenerative spine from 2013 to 2016. The Pearson correlation, Spearman correlation, and multivariate liner analysis were used to find association between patient characteristics and HBL. A total of 107 consecutive patients who underwent anterior cervical fusion surgery for degenerative spine in our hospital were reviewed. The amount of HBL was 261 mL, or 50% of the total blood loss. According to the model of multiple linear regression analysis, patient sex (P = 0.028) and American Society of Anesthesiologists physical status classification (P = 0.029) were independent risk factors contributing to HBL, but preoperative hematocrit was not (P = 0.741). We concluded that sex and American Society of Anesthesiologists physical status classification were independent risk factors of HBL in anterior cervical fusion surgery. In addition, there was a high proportion of HBL in anterior cervical fusion. When considering the strategies of transfusion, we should pay attention to the risk factors for HBL.

    Multicenter retrospective case series and review of the literature. To determine the rate of esophageal perforations following anterior cervical spine surgery. As part of an AOSpine series on rare complications, a retrospective cohort study was conducted among 21 high-volume surgical centers to identify esophageal perforations following anterior cervical spine surgery. Staff at each center abstracted data from patients' charts and created case report forms for each event identified. Case report forms were then sent to the AOSpine North America Clinical Research Network Methodological Core for data processing and analysis. The records of 9591 patients who underwent anterior cervical spine surgery were reviewed. Two (0.02%) were found to have esophageal perforations following anterior cervical spine surgery. Both cases were detected and treated in the acute postoperative period. One patient was successfully treated with primary repair and debridement. One patient underwent multiple debridement attempts and expired. Esophageal perforation following anterior cervical spine surgery is a relatively rare occurrence. Prompt recognition and treatment of these injuries is critical to minimizing morbidity and mortality.

    Full Text Available Bi Mo,1 Vishnu Garla,2 Lawrence M Wyner1 1Department of Surgery, 2Department of Internal Medicine, Marshall University, Huntington, WV, USA Background: Congenital unilateral absence of the vas deferens occurs in 0.5%–1.0% of males. It has been associated with various genitourinary abnormalities, including renal agenesis. We report a case of congenital unilateral absence of the vas deferens found incidentally during vasectomy in a patient with known unilateral renal agenesis. Case presentation: A 24-year-old male presented to our urology clinic requesting vasectomy. His past history was significant for left renal agenesis. Following successful right vasectomy, several attempts to locate the left vas deferens were unsuccessful. We diagnosed congenital unilateral absence of the vas deferens. Follow-up semen analysis showed azoospermia. Conclusion: As vasectomies are increasingly performed in outpatient settings, it is imperative that physicians be aware of this condition, which can be recognized by a simple physical exam. Recognition could prevent unnecessary surgery and prompt providers to investigate for associated abnormalities. Keywords: vas deferens, embryology, abnormalities, surgery

    Full Text Available Goal. To establish a reliable instrumental system for synchronized reactivation of a unilaterally paralyzed vocal fold and evaluate its functional feasibility. Methods. Unilateral vocal fold paralysis model was induced by destruction of the left recurrent laryngeal nerve (RLN in anesthetized dogs. With a micro controller-based electronic system, electromyography (EMG signals from cricothyroid (CT muscle on the ipsilateral side were recorded and used to trigger pacing of paralyzed vocalis muscles. The dynamic movement of vocal folds was continuously monitored using an endoscope, and the opening and closing of the glottis were quantified with customized imaging processing software. Results. The recorded video images showed that left side vocal fold was obviously paralyzed after destructing the RLN. Using the pacing system with feedback triggering EMG signals from the ipsilateral CT muscle, the paralyzed vocal fold was successfully reactivated, and its movement was shown to be synchronized with the healthy side. Significance. The developed unilateral laryngeal pacing system triggered by EMG from the ipsilateral side CT muscle could be successfully used in unilateral vocal fold paralysis with the advantage of avoiding disturbance to the healthy side muscles.

    Full Text Available Unilateral Neglect Syndrome is one of the consequences of cerebral vascular accident (CVA generally following right parietal lobe lesion, leading to the impairment of perceptive visual, spatial and attention functions. The patient affected does not realize the environmental stimuli on the contralesional hemibody. Occupational therapy plays an important role in caring for this patient, seeking the recovery of perception, attention and social engagement. This study aimed to describe and evaluate the results of occupational therapy intervention and treatment in a single Unilateral Neglect Syndrome post CVA patient. Data were obtained from a survey of the patient’s medical records and interviews of his therapist and caretaker. The analysis of the patient’s medical records and his therapist’s report showed that the patient responded satisfactorily to treatment, presenting a decrease of the left unilateral neglect at the end of the study period. The favorable outcome of the patient outlined the relevance of evaluating the effects of Occupational Therapy interventions for clinical unilateral neglect syndrome.

    Objective To investigate the relationship between the shoulder gradient and acromiohumeral interval of both shoulders in patients with unilateral shoulder impingement syndrome. Method Using the angulometer, we measured the shoulder gradient in patients with unilateral shoulder impingement syndrome in a standing position. Using the radiography, we measured the acromiohumeral interval and the angle between a vertical line and a line connecting a superior angle with an inferior angle of the scapula. Results In patients with unilateral shoulder impingement syndrome, the frequency of shoulder impingement syndrome was 76.2% (16 of 21) on the side of the relatively lower shoulder. The mean acromiohumeral interval on the side of the lower shoulder was 10.03±1.28 mm, compared with 10.46±1.50 mm for the higher shoulder. The angle between a vertical line and a line connecting a superior angle with an inferior angle of the scapular of the side of the lower shoulder was -0.31±3.73 degrees, compared with 3.85±4.42 degrees for the higher shoulder. Conclusion The frequency of shoulder impingement syndrome was significantly higher on the side of the relatively lower shoulder, and there is no significant difference in the acromiohumeral interval between the side of the lower shoulder and that of the higher shoulder. In patients with unilateral shoulder impingement syndrome, the scapular on the side of lower shoulder was more rotated downward than on the side of the higher shoulder. PMID:22506196

    To investigate the relationship between the shoulder gradient and acromiohumeral interval of both shoulders in patients with unilateral shoulder impingement syndrome. Using the angulometer, we measured the shoulder gradient in patients with unilateral shoulder impingement syndrome in a standing position. Using the radiography, we measured the acromiohumeral interval and the angle between a vertical line and a line connecting a superior angle with an inferior angle of the scapula. In patients with unilateral shoulder impingement syndrome, the frequency of shoulder impingement syndrome was 76.2% (16 of 21) on the side of the relatively lower shoulder. The mean acromiohumeral interval on the side of the lower shoulder was 10.03±1.28 mm, compared with 10.46±1.50 mm for the higher shoulder. The angle between a vertical line and a line connecting a superior angle with an inferior angle of the scapular of the side of the lower shoulder was -0.31±3.73 degrees, compared with 3.85±4.42 degrees for the higher shoulder. The frequency of shoulder impingement syndrome was significantly higher on the side of the relatively lower shoulder, and there is no significant difference in the acromiohumeral interval between the side of the lower shoulder and that of the higher shoulder.

    To analyze different patterns of vertical strabismic deviations seen in unilateral superior oblique (SO) paresis, and the response to surgical treatment, in order to discern the most effective surgical indication to treat each clinical pattern. A retrospective analysis of 110 patients with a diagnosis of unilateral SO paresis studied according to the follow protocol: a) Hypertropia (HT) measurement with alternate prism and cover test in the 9 diagnostic gaze positions; b) Determination of the deviation pattern; and c) Analysis of the results achieved with various surgical procedures. We found that unilateral SO paresis presented with 3 patterns of HT: 1) Patients with marked incomitance between opposite lateroversions; 2) Cases with HT equal to or greater than 20 prism diopters in primary gaze position, lower incomitance between opposite lateroversions and incomitance in up- and downgaze; and 3) A pattern of vertical deviation characterized by a strong tendency to comitance in the 9 diagnostic gaze positions, with an overtly positive Bielschowsky Head Tilt Test and extorsion of the affected eye. This study provides guidelines to discern the most effective surgical indication for patients with unilateral SO paresis on the basis of the presenting hypertropia pattern.

    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.

    Objective We present a patient with unilateral sudden sensorineural hearing loss (SSNHL) who was found to have a vascular loop in the ipsilateral internal auditory canal (IAC), and we review the literature regarding this association. Underlying pathophysiologic factors surrounding microvascular compression of the vestibulocochlear nerve are poorly understood and make treatment recommendations, especially the option of microvascular decompression, difficult if not controversial. The current report represents an attempt to understand this clinical entity as discussed in the current literature. Case summary: A 77-year-old female with a long history of progressive right-sided hearing loss and episodic vertigo developed unilateral right SSNHL, tinnitus, vertigo, and disequilibrium. She was originally diagnosed with a vestibular schwannoma on magnetic resonance imaging (MRI) and was referred to our institution for Gamma Knife radiosurgery. Repeat MRI demonstrated a loop of the anterior inferior cerebellar artery (AICA) compressing the vestibulocochlear nerve within the right IAC. There was no evidence of a schwannoma on the repeat MRI. She was not offered radiosurgery, and she elected conservative management. Conclusion Vascular compression of cranial nerves can lead to neuronal dysfunction, and this has been rarely described in patients involving the vestibulocochlear nerve complex. There is evidence that microvascular decompression (MVD) of the vestibulocochlear nerve can be effective in selected patients who exhibit pulsatile tinnitus or disabling positional vertigo in the setting of a vascular loop within the ipsilateral IAC, but available evidence at this time does not support MVD for SSNHL.

    Individuals with unilateral transfemoral amputation demonstrate significantly increased rates of osteoarthritis in their sound knee. This increased risk is likely the result of altered knee mechanical loading and gait compensations resulting from limited function in the prosthetic limb. Altered knee loading as calculated using loading rates and peak external knee adduction moments and impulses have been associated with both the development and progression of knee osteoarthritis in other populations. The purpose of this study was to determine if young individuals with transfemoral amputation demonstrate biomechanical indicators of increased knee osteoarthritis risk. Fourteen young male Service Members with unilateral transfemoral amputation and 14 able-bodied service members underwent biomechanical gait analysis at three standardized walking velocities. A two-way ANOVA (group × speed) with unpaired comparisons with Bonferroni-Holm post-hoc corrections assessed statistical significance and effect sizes (d) were calculated. Normalized peak external knee adduction moments and impulses were 25.7% (P 0.994) and 27.1% (P 1.019) lower, respectively, in individuals with trans-femoral amputation than controls when averaged across speeds, and effect sizes were large. External knee flexor moments were not, however, different between groups and effect sizes were generally small (P > 0.380, d amputation and effect sizes were large (P 1.644). Individuals with transfemoral amputation did not demonstrate biomechanical risk factors for high medial compartment knee joint loads, but the increased loading rates could place the sound knee at greater risk for cartilage or other tissue damage, even if not localized to the medial compartment.

    Full Text Available BackgroundThe aim of unilateral breast reconstruction after mastectomy is to craft a natural-looking breast with symmetry. The latissimus dorsi (LD flap with implant is an established technique for this purpose. However, it is challenging to obtain adequate volume and satisfactory aesthetic results using a one-stage operation when considering factors such as muscle atrophy, wound dehiscence and excessive scarring. The two-stage reconstruction addresses these difficulties by using a tissue expander to gradually enlarge the skin pocket which eventually holds an appropriately sized implant.MethodsWe analyzed nine patients who underwent unilateral two-stage LD reconstruction. In the first stage, an expander was placed along with the LD flap to reconstruct the mastectomy defect, followed by gradual tissue expansion to achieve overexpansion of the skin pocket. The final implant volume was determined by measuring the residual expander volume after aspirating the excess saline. Finally, the expander was replaced with the chosen implant.ResultsThe average volume of tissue expansion was 460 mL. The resultant expansion allowed an implant ranging in volume from 255 to 420 mL to be placed alongside the LD muscle. Seven patients scored less than six on the relative breast retraction assessment formula for breast symmetry, indicating excellent breast symmetry. The remaining two patients scored between six and eight, indicating good symmetry.ConclusionsThis approach allows the size of the eventual implant to be estimated after the skin pocket has healed completely and the LD muscle has undergone natural atrophy. Optimal reconstruction results were achieved using this approach.

    The aim of our study was to identify clinical criteria for optimizing rehabilitation of patients with unilateral deafness using the Baha device. We made a retrospective study of 102 patients with unilateral deafness requesting auditory rehabilitation over a period of 5 years. All subjects underwent a series of stereo audiometric tests, with and without Baha worn on a headband, and were then referred to a hearing care specialist for a real life trial of 15 days. The Glasgow Health Status Inventory (GHSI) questionnaire was administered. Patients refusing the implantation were retrospectively submitted to a questionnaire specifically designed to ask the reasons for refusal. We measured stereo audiometric test results, age, aetiology of deafness, duration of auditory deprivation on the rehabilitated ear, and GHSI score. At the conclusion of testing, the implantation rate was 29%. During preoperative testing, the improvement in understanding of speech-in-noise was 22 ± 11% for patients agreeing to the implantation versus 13 ± 11% for patients refusing the implantation. Age, aetiology of deafness and duration of auditory deprivation had no influence on the implantation decision. Speech-in-noise testing and aided stereo audiometric gain were the only two measures showing statistically significant differences between the groups agreeing to and refusing the implantation. There were multiple reasons for refusal of the implantation. Among these, the four principal reasons were: absence of perceived benefit during stereo audiometric testing (59%), requirement for surgery (35%), cost of the solution (44%), and aesthetics (41%). Hence, no other criteria except the preoperative improvement in understanding of speech-in-noise and the aided gain from Baha worn on a headband were found to be predictive of the patient's acceptance of surgical implantation of a bone-anchored implant/abutment for Baha. Speech-in-noise testing with and without Baha worn on a headband has a role to

    To identify the rate of hearing loss related to middle ear disease and the frequency of tympanostomy tube (TT) insertion in the contralateral ear of patients with unilateral microtia/aural atresia. Retrospective case series of patients less than 3 years of age with unilateral microtia/aural atresia treated at an urban, tertiary care children's hospital from 2008 to 2013. Clinical and audiologic data were reviewed. Statistical analysis was performed to determine the relative risk of TT insertion in the normal ear. A total of 72 patients were included for analysis. The average age of patients at their initial otolaryngology visit was 3.3 months (range 0.08-1.67 years); 38 (52.8%) patients were males. Aural atresia involved the right ear in 43 (59.7%) cases. Five (6.9%) patients were syndromic. Abnormal audiometric testing of the normal ear was noted in 12 (16.7%), and 14 (19.4%) underwent TT during the first 3 years of life. Twelve children (85.7%) who had a TT placed were nonsyndromic. When compared to published norms for TT placement in the general population (6.8% of children atresia had TT placement in the normal ear (z = 4.26, P atresia have increased rates of hearing loss and middle ear effusion leading to TT in their normal ear at a higher rate versus the general population. This information can help guide more vigilant care and audiologic follow-up in affected children. 4.

    The purpose of this study was to determine whether hydrocele has any effect on the volume and shape of the ipsilateral testis and can be implicated as a cause of testicular ischemia. Group 1 consisted of 23 patients with unilateral idiopathic hydrocele, whereas 30 healthy men constituted group 2. All patients underwent scrotal ultrasonography by which testicular dimensions in craniocaudal (D(cc)), anteroposterior (D(ap)), and mediolateral axes were measured, followed by calculation of the D(cc)/D(ap) ratio and testicular volume. By color Doppler analysis, the resistivity index of the subcapsular artery (RI(sc)) and the resistivity index of the intratesticular artery were determined. The mean D(cc)/D(ap) ratio +/- SD for group 1 was 1.7 +/- 0.3 (range, 1.1-2.3), significantly lower than that of group 2, which was 1.9 +/- 0.3 (range, 1.3-2.2) (P = .028). Mean testicular volume values of subjects having hydrocele for more than and less than 6 months were 13.4 +/- 7.3 and 22.5 +/- 5.1 cm3, respectively; the difference between the subgroups was significant (P = .003). For the ipsilateral testis, mean RI(sc) values were 0.70 +/- 0.06 (range, 0.60-0.80) in group 1 and 0.65 +/- 0.06 (range, 0.59-0.83) in group 2. The mean RI(sc) was significantly higher in group 1 (P = .006). Unilateral idiopathic hydrocele has a tendency for rounding rather than flattening the ipsilateral testis as well as elevating the RI(sc) on the affected side. To the best of our knowledge, no strict spectral Doppler analysis criteria have been proposed for testicular ischemia yet. Therefore, the impact of the difference of the RI(sc) should raise the suspicion for ischemia, and further research is needed to elucidate any effect on spermatogenesis.

Este estudo avalia o controle postural em pacientes portadores de lesão unilateral do ligamento cruzado anterior do joelho e de indivíduos saudáveis, através de parâmetros do centro de pressão. Dezenove indivíduos saudáveis entre 18 e 30 anos e dezenove pacientes portadores de lesão unilateral do ligamento cruzado anterior do joelho entre 15 e 33 anos foram avaliados empregando sensores FSCAN MAT® (Tekscan®, Boston, MA, USA. Todos os indivíduos realizaram quatro testes estáticos diferentes com apoio unilateral, variando os lados e a abertura e o fechamento dos olhos. Os parâmetros comprimento total da trajetória, amplitude antero-posterior, amplitude médio-lateral e velocidade máxima do centro de pressão foram calculados. Os resultados mostraram que a dominância dos membros inferiores não exerce influência significativa no equilíbrio dos indivíduos saudáveis, que a visão é um fator importante na estabilização do controle postural e que a lesão unilateral do ligamento cruzado anterior do joelho compromete o equilíbrio em apoio unilateral e em ambos os lados, porém, de modo mais evidente, no lado lesado.Standing balance is the process which keeps the pressure center, vertical projection of the centre of gravity on ground inside the body weight-bearing.

    Purpose To evaluate the prevalence and risk factors of strabismus in children undergoing surgery for unilateral or bilateral cataract with or without intraocular lens implantation. Methods Medical records of pediatric patients were evaluated from 2000 to 2011. Children undergoing surgery for unilateral or bilateral cataract with at least 1 year of follow-up were included. Children with ocular trauma, prematurity, or co-existing systemic disorders were excluded. The following data were evaluated: strabismus pre- and post-operation; age at surgery; post-operative aphakia or pseudophakia; and visual acuity. Results Ninety patients were included, 40% had unilateral and 60% had bilateral cataracts. Follow-up was on average 51 months (range: 12–130 months). Strabismus was found preoperatively in 34.4% children, and in 43.3% children at last follow-up. Strabismus developed in 46.2% of children who were orthotropic preoperatively, whereas 32.3% of children who had strabismus before surgery became orthotropic. Strabismus occurred after unilateral or bilateral cataract surgery in 63.9% and 29.6% children, respectively. At the last follow-up, strabismus was found in 46.7% of aphakic and 58.7% of pseudophakic children (P=0.283). Children who developed strabismus were generally operated at a younger age as compared with those without strabismus (mean of 25.9 vs 52.7 months, Pstrabismus. Conclusion Strabismus is a frequent complication after cataract surgery in children. Risk factors include unilateral cases and young age at surgery. No correlation was found between prevalence of strabismus and use of intraocular lens. Strabismus was more common in children with poor final visual acuity. PMID:27472210

    2010-10-01

    Retrospective review of the CT scans performed in a group of patients examined for a possible spondylolysis. To investigate whether there is an association between unilateral spondylolysis and facet joint tropism. Spondylolysis is a fatigue fracture of the pars interarticularis of great importance in sports injury. The demonstration of a unilateral spondylolysis is important because there is a potential for full healing if the athletic activity is modified, whereas bilateral spondylolysis frequently leads to established nonunion. Coronally orientated facet joints are known to predispose to spondylolysis by increasing the point loading of the pars interarticularis. The importance of this finding has not been investigated in unilateral spondylolysis. A review of patients with low back pain and a possible diagnosis of spondylolysis who were investigated with multislice CT was performed. The coronal orientation of the facet joints at L4/5 and L5/S1 was measured and comparison was done between those with and without a spondylolysis. The coronal angle of 140 facet joints in 35 patients was recorded. Of 35 patients, 23 had a spondylolysis which was unilateral in 12 patients. The facet joint angle was significantly more coronally orientated in the presence of a spondylolysis when compared with an intact pars (means, 53° and 43°, respectively; P spondylolysis, the facet joint was significantly more coronally orientated on the side of the spondylolysis (means, 52° and 45°, respectively; P spondylolysis. Asymmetric facet joints do increase the force through one side of the spine, with a unilateral spondylolysis occurring on the side of the more coronally orientated facet joint.

    Non-steroidal anti-inflammatory drugs (NSAIDs), transdermal fentanyl patches, and transmucosal buprenorphine are probably the most commonly used options for providing post-operative analgesia in the early at-home period. However, these require daily administration or are associated with abuse concerns. One of the significant unmet needs in veterinary surgery and pain management is for longer acting opioids for cats to effectively bridge the gap between the in-hospital and at-home recovery periods. A proof of concept study of an extended release formulation of buprenorphine HCL (ER-Bup) was conducted using objective kinetic measures and a unilateral onychectomy model. Using a blinded, randomized, two period crossover design, four cats were allocated to control (saline) or ER-Bup (0.6 mg/kg, subcutaneously [SC]) treatment groups. All animals underwent a unilateral forelimb onychectomy per period with a washout/recovery period in between. Observational pain scores and kinetic data (using a pressure sensitive walkway [PSW]) were collected prior to (baseline) and at intervals for 72 h following surgery. Symmetry indices were derived for kinetic variables (peak vertical force [PVF]; vertical impulse [VI]) of each forelimb for landing following a jump and for walking. A rescue analgesic protocol was in place. Effect of surgery and treatment were evaluated using a mixed model statistical approach. No cats required rescue analgesics based on subjective pain score. ER-Bup had a positive influence on subjective pain scores during the 72 h postsurgery (p = 0.0473). PVF and VI of the operated limb were significantly decreased for both landing (p < 0.0001 and p < 0.0001) and walking (p < 0.0001 and p < 0.0001 respectively) compared to control. ER-Bup resulted in significantly decreased asymmetry in limb use during landing (PVF, p < 0.0001; VI, p < 0.0001) and walking (PVF, p = 0.0002, VI, p < 0.0001). The novel use of data collected

    Full Text Available OBJETIVO: A cirurgia torácica vídeo-assistida (CTVA tem sido uma intervenção de escolha para o tratamento de pneumotórax espontâneo (PS com bolha pulmonar. Nosso objetivo foi apresentar uma abordagem de CTVA uniportal unilateral para bulectomia bilateral e avaliar sua eficácia terapêutica. MÉTODOS: Entre maio de 2011 e janeiro de 2012, cinco pacientes foram submetidos a bulectomia bilateral por essa abordagem. Todos apresentavam PS bilateral. A TCAR pré-operatória mostrou que todos os pacientes tinham bolhas bilaterais no pulmão apical. As indicações cirúrgicas, os procedimentos de operação e os desfechos foram revisados. RESULTADOS: Todos os pacientes foram submetidos com sucesso a essa abordagem para bulectomia bilateral, sem complicações intraoperatórias. A mediana de tempo para a retirada do dreno torácico foi de 4,2 dias, e a mediana do tempo de hospitalização no pós-operatório foi de 5,2 dias. A mediana de seguimento pós-operatório foi de 11,2 meses. Um paciente teve recidiva de PE do lado esquerdo três semanas após a cirurgia e foi submetido a abrasão pleural. CONCLUSÕES: A bulectomia bilateral utilizando CTVA uniportal combinada com acesso contralateral ao mediastino anterior é tecnicamente confiável e promove desfechos favoráveis para pacientes com PS que desenvolvem bolhas bilaterais no pulmão apical. Entretanto, para a realização desse procedimento cirúrgico, são necessários cirurgiões com experiência em CTVA, instrumentos toracoscópicos longos, entre outras exigências.OBJECTIVE: Video-assisted thoracoscopic surgery (VATS has been a surgical intervention of choice for the treatment of spontaneous pneumothorax (SP with lung bulla.

    We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

    Anterior cervical spine procedures have been associated with satisfactory outcomes. However, the occurrence of troublesome complications, although uncommon, needs to be taken into consideration. The purpose of our study was to assess the actual incidence of anterior cervical spine procedure-associated complications and identify any predisposing factors. A total of 114 patients undergoing anterior cervical procedures over a 6-year period were included in our retrospective, case-control study. The diagnosis was cervical radiculopathy, and/or myelopathy due to degenerative disc disease, cervical spondylosis, or traumatic cervical spine injury. All our participants underwent surgical treatment, and complications were recorded. The most commonly performed procedure (79%) was anterior cervical discectomy and fusion (ACDF). Fourteen patients (12.3%) underwent anterior cervical corpectomy and interbody fusion, seven (6.1%) ACDF with plating, two (1.7%) odontoid screw fixation, and one anterior removal of osteophytes for severe Forestier's disease. Mean follow-up time was 42.5 months (range, 6-78 months). The overall complication rate was 13.2%. Specifically, we encountered adjacent intervertebral disc degeneration in 2.7% of our cases, dysphagia in 1.7%, postoperative soft tissue swelling and hematoma in 1.7%, and dural penetration in 1.7%. Additionally, esophageal perforation was observed in 0.9%, aggravation of preexisting myelopathy in 0.9%, symptomatic recurrent laryngeal nerve palsy in 0.9%, mechanical failure in 0.9%, and superficial wound infection in 0.9%. In the vast majority anterior cervical spine surgery-associated complications are minor, requiring no further intervention. Awareness, early recognition, and appropriate management, are of paramount importance for improving the patients' overall functional outcome.

    Full Text Available We describe a case of a 67-year-old woman with severe disabling right-sided tinnitus, mild hyperacusis, and headache. The tinnitus was associated with sudden right hearing loss and vertigo, which occurred about 18 months before. Magnetic resonance imaging (MRI resulted in normal anatomical structures of the cochlea and of the cranial nerves showing a partial empty sella syndrome with suprasellar cistern hernia. Angio-MR revealed a bilateral contact between the anterior-inferior cerebellar artery (AICA and the acoustic-facial nerve with a potential neurovascular conflict. Surgery was considered unnecessary after further evaluations. The right ear was successfully treated with a combination device (hearing aid plus sound generator. Shortly after a standard fitting procedure, the patient reported a reduction of tinnitus, hyperacusis, and headache which completely disappeared at the follow-up evaluation after 3, 6, and 12 months. This paper demonstrates that the combination device resulted in a complete tinnitus and hyperacusis suppression in a patient with unilateral sensorineural sudden hearing loss. Our paper further supports the restoration of peripheral sensory input for the treatment of tinnitus associated with hearing loss in selected patients.

    Maxillary growth in patients with cleft lip and palate is highly variable. The authors' aim was to investigate associations between preoperative cleft lip measurements and maxillary growth determined cephalometrically in patients with complete unilateral cleft lip and palate (cUCLP). Retrospective cross-sectional study. Children with cUCLP. Preoperative cleft lip measurements were made at the time of primary cheiloplasty and available for each patient. Maxillary growth was evaluated on lateral cephalometric radiographs taken prior to any orthodontic treatment and alveolar bone grafting (8.5 ± 0.7 years). The presence of associations between preoperative cleft lip measurements and cephalometric measures of maxillary growth was determined using regression analyses. In the 58 patients included in the study, the cleft lateral lip element was deficient in height in 90% and in transverse width in 81% of patients. There was an inverse correlation between cleft lateral lip height and transverse width with a β coefficient of -0.382 (P = .003). Patients with a more deficient cleft lateral lip height displayed a shorter maxillary length (β coefficient = 0.336; P = .010), a less protruded maxilla (β coefficient = .334; P = .008), and a shorter anterior maxillary height (β coefficient = 0.306; P = .020) than those with a less deficient cleft lateral lip height. Patients with cUCLP present with varying degrees of lateral lip hypoplasia. Preoperative measures of lateral lip deficiency are related to later observed deficiencies of maxillary length, protrusion, and height.

    Full Text Available Purpose. We present a case with Klippel-Trenaunay (KT syndrome that had unilateral mature cataract and vitreoretinopathy. Case Report. A 17-year-old boy with KT syndrome presented to the clinic of ophthalmology for low vision in the right eye. His best corrected visual acuity (BCVA was hand motion in the right eye and 20/20 in the left eye. Anterior segment examination revealed mature cataract in the right. During the physical examination, port-wine stains were noted over right side of his face, ankle, and toes. He had asymmetric face and his head was larger on the right side. Leg lengths were symmetrical, although he had skin hypertrophy. Cranial magnetic resonance imaging studies showed cortical atrophy discordant to his age, asymmetric vascular dilatations in the right hemisphere, hypertrophy in the right periorbital soft tissue, and choroidal plexus. The patient received an uncomplicated cataract surgery. His BCVA in the right eye improved to 20/200 after the surgery. After removing cataractous lens, we were able to examine the fundus that revealed severe vitreoretinopathy and choroidal hemangioma. Conclusion. This case emphasizes the importance of prompt ophthalmic examination in patients with KT syndrome.

    Full Text Available Recent studies have emphasized the association between tubulin gene mutations and developmental abnormalities of the cortex. In this study, the authors identified a mutation in the tubulin-encoding class III β-tubulin ( TUBB3 gene in a 4-year-old boy presenting with brain abnormalities and unilateral hypohidrosis. The patient showed a left internal strabismus, moderate developmental delay, and congenital hypohidrosis of the right side of the body. Magnetic resonance imaging disclosed gyral disorganization mainly in the left perisylvian region, dysmorphic and hypertrophic basal ganglia with fusion between the putamen and caudate nucleus without affecting the anterior limb of the internal capsule, and moderate hypoplasia of the right brain stem and cerebellum. Diffusion tensor imaging studies revealed disorganization of the pyramidal fibers. The amplitude of the sympathetic skin response was low in the right arm, which led to a diagnosis of focal autonomic neuropathy. Sequencing the TUBB3 gene revealed a de novo missense mutation, c.862G>A (p.E288K.

    Acute unilateral nephrectomy (AUN) results in natriuresis from the remaining kidney through reflex pathways involving the central nervous system and requiring an intact pituitary gland. The natriuresis is accompanied by an increase in the plasma concentration of a peptide or peptides derived from the N-terminal fragment (NTF) of proopiomelanocortin. The authors measured plasma immunoreactive NTF-like material (IR-NTF) by radioimmunoassay, before and after AUN in control rats and rats treated neonatally with monosodium glutamate (MSG), a procedure that produces neuroendocrine dysfunction by destroying cell bodies in the hypothalamic arcuate nucleus, median eminence, and other brain regions. In control rats, IR-NTF increased from 85.8 +/- 54.9 (SD) to 207 +/- 98.1 fmol/ml after AUN as sodium excretion (U/sub Na/V) doubled. In MSG-treated rats, AUN produced no change in plasma IR-NTF concentration, nor did U/sub Na/V increase. Tissue content of IR-NTF was reduced in the arcuate nucleus and anterior lobe of pituitaries from MSG-treated rats compared with controls, but was no different in the neurointermediate lobe. These results indicate that the hypothalamic lesion produced by neonatal administration of MSG prevents both the increase in plasma IR-NTF concentration and the natruiuresis after AUN, and therefore lend further support to the concept of a casual relationship between these two consequences of AUN.

    Abstract Background: Cervical disc replacement (CDR) has been developed as an alternative surgical procedure to anterior cervical discectomy and fusion (ACDF) for the treatment of single-level cervical degenerative disc disease. However, patients with multilevel cervical degenerative disc disease (MCDDD) are common in our clinic. Multilevel CDR is less established compared with multilevel ACDF. This study aims to compare the outcomes and evaluate safety and efficacy of CDR versus ACDF for the treatment of MCDDD. Methods: A meta-analysis was performed for articles published up until August 2016. Randomized controlled trials (RCTs) and prospective comparative studies associated with the use of CDR versus ACDF for the treatment of MCDDD were included in the current study. Two reviewers independently screened the articles and data following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Results: Seven studies with 702 enrolled patients suffering from MCDDD were retrieved. Patients who underwent CDR had similar operative times, blood loss, Neck Disability Index (NDI) scores, and Visual Analog Scale (VAS) scores compared to patients who underwent ACDF. Patients who underwent CDR had greater overall motion of the cervical spine and the operated levels than patients who underwent ACDF. Patients who underwent CDR also had lower rates of adjacent segment degeneration (ASD). The rate of adverse events was significantly lower in the CDR group. Conclusion: CDR may be a safe and effective surgical strategy for the treatment of MCDDD. However, there is insufficient evidence to draw a strong conclusion due to relatively low-quality evidence. Future long-term, multicenter, randomized, and controlled studies are needed to validate the safety and efficacy of multilevel CDR. PMID:28422837

    The purpose of this work was to analyze variations in maxillary arch dimensions in subjects presenting unilaterally impacted maxillary permanent central incisors compared with a control group of subjects without eruption anomalies. A group of 23 Caucasian children [8 females and 15 males, mean age 9.7 years, standard deviation (SD) 1.6 years] displaying unilaterally impacted maxillary permanent central incisors (impacted incisor group: IIG) were compared with a control group (CG) of 23 subjects (9 females; 14 males, mean age 8.8 years, SD 1.9 years) presenting no eruption disorders. Pretreatment dental casts were taken from each subject and the upper arch was scanned using a three-dimensional scanner. Linear measurements were taken on each digital model to analyze maxillary arch dimensions. Significant between-group differences were tested with the Student's t test (p < 0.05). The transverse and sagittal upper-arch measurements were significantly smaller in the IIG than in the CG. In particular, the anterior arch was 1.35 mm shorter in the IIG, while intercanine width was decreased by 2.51 mm on the impacted side. Children revealing unilaterally impacted maxillary central incisors demonstrated a significantly constricted maxillary transverse width and shorter arch on the impacted side compared with subjects with no eruption disorders.

    Full Text Available O presente estudo trata do caso de um paciente que apresentou incontinência do choro e hemiplegia direita por infarto ventroprotuberancial paramediano detectado pela RNM. O caráter circunscrito da lesão foi endossado pela normalidade dos potenciais evocados sômato-sensitivos e auditivos de curta-latência. Os episódios de choro desapareceram poucos dias depois do início do tratamento com doses baixas de imipramina. Discutimos o choro e riso patológicos como forma de incontinência da mímica resultante de desconexão límbico-motora, enfatizando a impropriedade de incluí-los na síndrome pseudobulbar, uma vez que dependem de correlatos anatômicos e funcionais distintos.A 64-year-old man presented with pathologic crying and right hemiplegia due to a unilateral pontine infarct from probable branch disease of the basilar artery. The circumscribed nature of the lesion was supported by MRI and short-latency evoked potentials. The weeping spells ceased after a few days of imipramine in low doses. Pathologic laughing and crying can be viewed as a limbic-motor disconnection syndrome, in which the faciovocal motor system is released from forebrain afferents carrying information of emotional content. The inclusion of pathologic laughing and crying in the syndrome pseudobulbar palsy is inaccurate and misleading, since each is related to distinct functional and anatomic systems intrinsic to the human brainstem.

    Full Text Available Although several risk factors for anterior cruciate ligament (ACL injury have been evaluated in the literature, there are few reports on familial predisposition. This study investigated the familial predisposition to ACL injury. The study included 350 patients who underwent ACL reconstruction between January 2005 and September 2008. All patients were surveyed by telephone or a written questionnaire about family history (FH of ACL injury, sports played by family members, and mechanisms of injury. We also compared age, sex, height, weight, body mass index, Tegner activity score, general joint laxity, and tibial slope between an FH group (with FH and a control group (without FH. In addition, we compared the incidence of ACL graft rupture and contralateral ACL rupture 2 years after primary surgery. Complete information was obtained from 316 patients, 38 (12.0% of whom had FH of ACL injury. Two families had three members with ACL injuries. Of the 40 family members with ACL injuries, 38 (95% had noncontact injuries and 34 (85% shared a similar mechanism of injury with the related patient. No significant differences were identified between the two groups, except that tibial slope was significantly greater in the FH group than in the control group. Although the incidence of repeat ACL injury was greater in the FH group (23.7% than in the control group (16.4%, there was no significant difference. Our results indicated a high probability of familial predisposition to many of the identified risk factors for ACL injury. In addition, patients with FH of ACL injury might be at high risk for initial and repeat ACL injuries. Therefore, prevention programs should be implemented for patients with FH of ACL injury in order to decrease the risk of these injuries.

    A 42-year-old woman presented with Hunt and Hess grade (HHG) III subarachnoid hemorrhage (SAH) caused by a ruptured left distal anterior inferior cerebellar artery (AICA) aneurysm. Computed tomography showed a thin SAH on the cerebellopontine angle cistern, and small vermian intracerebral hemorrhage and intraventricular hemorrhage in the fourth ventricle. Digital subtraction angiography revealed the aneurysm on the postmeatal segment of left distal AICA, a branching point of rostrolateral and caudomedial branch of the left distal AICA. Despite thin caliber, tortuous running course and far distal location, the AICA aneurysm was obliterated successfully with endovascular coils without compromising AICA flow. However, the patient developed left side sensorineural hearing loss postoperatively, in spite of definite patency of distal AICA on the final angiogram. She was discharged home without neurologic sequela except hearing loss and tinnitus. Endovascular treatment of distal AICA aneurysm, beyond the meatal loop, is feasible while preserving the AICA flow. However, because the cochlear hair cell is vulnerable to ischemia, unilateral hearing loss can occur, possibly caused by the temporary occlusion of AICA flow by microcatheter during endovascular treatment.

    Purpose: The purpose of this study is to investigate the dosimetric feasibility of hypo-fractionated intensity modulated proton therapy (IMPT) for unilateral metallic prosthesis prostate cancer patients based on proton collaborative group (PCG)-GU002-10 (NCT01230866) protocol criteria. Methods: A total of five unilateral metallic prosthesis prostate cancer cases were included in this retrospective study. For each case, IMPT plans were generated for treatment to be delivered with 7.6 Gy[RBE] per fraction in 5 fractions per week for a total dose of 38 Gy(RBE). Each plan was generated using two anterior-oblique beams and one lateral beam. Treatment plans were optimized with an objective meeting PCG-GU002-10 (NCT01230866) protocol criteria: (i) planning target volume (PTV): D99.5% > 36.1 Gy[RBE], (ii) rectum: V24 < 35%, V33.6 < 10%, (iii) bladder: V39 < 8 cc, and (iv) femoral head: V23 < 1cc. Results: All five cases satisfied PTV D99.5% (average=36.82 Gy[RBE]; range, 36.36–37.13 Gy[RBE]). PTV D95% ranged from 36.66 Gy[RBE] to 38.65 Gy[RBE] and PTV V100 ranged from 95.47% to 97.95%. For the rectum, V24 was less than 35% (average=14.07 Gy[RBE]; range, 6.22–18.42%, whereas V33.6 Gy[RBE] was less than 10% (average=6.83; range, 3.06 – 9.15%). Rectal mean dose ranged from 4.22 Gy[RBE] to 9.97 Gy[RBE]. For the bladder, V39 was found to be less than 8 cc (average=3.69 cc; range, 0.19–7.68 cc). Bladder mean dose ranged from 4.22 Gy[RBE] to 18.83 Gy[RBE]. For the femoral head, V23 was 0 in all five cases. Conclusion: All five unilateral metallic prosthesis prostate cancer IMPT plans generated with one lateral and two anterior-oblique beams satisfied the dosimetric criteria of PCG-GU002-10 (NCT01230866) protocol.

    Full Text Available Objective. The purpose of this study was to evaluate a new questionnaire to assess outcomes related to the midline anterior lumbar approach and to identify risk factors for negative patient responses. Methods. A retrospective review of 58 patients who underwent anterior lumbar surgery at a single institution for either degenerative disc disease or spondylolisthesis in 2009 was performed. The outcome measures included our newly developed Anterior Lumbar Surgery Questionnaire (ALSQ, ODI, and EQ-5D. Results. There were 58 patients available for followup, 27 women and 31 men. The average age at surgery was 50.8 years, with an average followup of 2.92 years. The average change in ODI was 34.94 (22.7 and EQ-5D was 0.28 (0.29. The rate of complications with the anterior approach was 10.3% and there was one male patient (3.2% with retrograde ejaculation. Determination of the effectiveness of the new ALSQ revealed that it significantly correlated to the EQ-5D and ODI (P<0.05. Smoking was associated with a negative response on thirteen questions. BMP use was not associated with a negative response on any sexual function questions. Conclusions. Our new Anterior Lumbar Surgery Questionnaire determines patient perceived complications related to the midline anterior lumbar surgical approach.

    Full Text Available O carcinoma epidermóide da laringe é a sexta neoplasia mais comum, sendo uma das neoplasias malignas mais freqüentes na cabeça e pescoço, ocupando o segundo lugar imediatamente após o câncer da cavidade oral. FORMA DE ESTUDO: Estudo clínico retrospectivo. MATERIAL E MÉTODO: Entre os anos de 1991 e 2003, 24 pacientes portadores de lesões glóticas envolvendo a comissura anterior foram submetidos a laringectomia frontal anterior com epiglotoplastia descrita por Tucker e colaboradores no ano de 1979. RESULTADO: Nossos resultados confirmam aqueles encontrados em outras publicações. Não ocorreram mortes no pós-operatório e o seguimento foi relativamente simples. Todos os pacientes foram decanulizados e recuperaram um efetivo trato digestivo e aéreo. CONCLUSÃO: Nossos achados mostram que a laringectomia pela técnica de Tucker é uma cirurgia efetiva para o tratamento dos carcinomas glóticos que acometem a comissura anterior e a porção membranosa das cordas vocais com a motilidade preservada, pois tais lesões não devem ser tratadas pela ressecção endoscópica trans-oral ou por uma laringectomia fronto lateral.Squamous cell carcinoma of the larynx is the sixth most common neoplasia, being the second neoplasia of the head and neck, after oral cancer. STUDY DESIGN: Retrospective clinical study chart review. MATERIAL AND METHOD: From 1991 to 2003, 24 patients whose glottic lesions involving anterior comissure were operated with a reconstructive anterior frontal laryngectomy with epiglotoplasty, such as described by Tucker et al in 1979. RESULTS: Our functional results confirm those reported in the previous publications. There were no post-operative mortalities and follow-up was usually uncomplicated. All patients underwent decanulation and were able to eat by tract normal. CONCLUSION: Our findings show that partial laryngectomy by Tucker's technique is an effective surgical approach for glottic carcinoma at the anterior comissure

  2. Anterior chest wall examination reviewed

    Full Text Available Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondiloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the “activity” of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

    Esquivel-Miranda, Miguel; De la O Ríos, Elier; Vargas-Valenciano, Emmanuelle; Moreno-Medina, Eva

    Schwannomas are nerve sheath tumours that originate in Schwann cells. They are usually solitary and sporadic and manifest on peripheral, spinal or cranial nerves. Intracranial schwannomas tend to manifest on the eighth cranial nerve, particularly in patients with neurofibromatosis type2. Anterior skull-base schwannomas represent less than 1% of all intracranial schwannomas. They are more frequent in young people and are typically benign. These tumours represent a diagnostic challenge due to their rarity and difficult differential diagnosis, and numerous theories have been postulated concerning their origin and development. In this article, we present the case of a 13-year-old male with a single anterior cranial-base tumour not associated with neurofibromatosis who presented with headache, papilloedema, eye pain and loss of visual acuity. Complete resection of the tumour was performed, which was histopathologically diagnosed as a schwannoma. The patient made a complete clinical recovery with abatement of all symptoms. We conducted a review of the literature and found 66 cases worldwide with this diagnosis. We describe the most relevant epidemiological and clinical characteristics of this kind of tumour and its relation with the recently discovered and similar olfactory schwannoma.

    This study was performed to investigate anterior ankle impingement after tendo-Achilles lengthening for long-standing equinus deformity in patients with residual poliomyelitis and to investigate whether the severity of preoperative equinus deformity affected the occurrence of symptomatic anterior impingement. Twenty-seven consecutive patients (mean age, 43.8 ± 9.4 years) with residual poliomyelitis who underwent tendo-Achilles lengthening for equinus foot deformity were included. On lateral foot-ankle weight-bearing radiographs, the tibiocalcaneal angle, plantigrade angle, and McDermott grade were measured and the presence of anterior blocking spur was evaluated. Eleven patients (40.7%) had anterior ankle impingement on radiographic findings preoperatively and 24 patients (88.9%) at latest follow-up. There was a significant difference in McDermott grade between preoperative and latest follow-up (P poliomyelitis had anterior ankle impingement after tendo-Achilles lengthening for long-standing equinus deformity, and the presence of symptomatic anterior ankle impingement was significantly associated with the severity of the equinus deformity. Therefore, for residual poliomyelitis patients with severe long-standing equinus deformity, surgeons should consider the possibility of a subsequent anterior procedure for anterior impingement after tendo-Achilles lengthening.

To compare the risk of aseptic revision between bone-patellar tendon-bone (BPTB) autografts and BPTB allografts. Cohort study; Level of evidence, 2.

A cohort of patients who underwent primary unilateral ACLR with BPTB autografts and BPTB allografts was identified. Aseptic revision was the endpoint. The type of graft and allograft processing method (nonprocessed, <1.8-Mrad, and ≥1.8-Mrad irradiation) were the exposures of interest evaluated. Age (≤21 and ≥22 years) was evaluated as an effect modifier. Analyses were adjusted for age, sex, and race. Kaplan-Meier curves and Cox proportional hazards models were employed. Hazard ratios (HRs) and 95% CIs are provided. The BPTB cohort consisted of 5586 patients: 3783 (67.7%) were male, 2359 (42.2%) were white, 1029 (18.4%) had allografts (nonprocessed: 155; <1.8 Mrad: 525; ≥1.8 Mrad: 288), and 4557 (81.6%) had autografts. The median age was 34.9 years (interquartile range [IQR], 25.4-44.0) for allograft cases and 22.0 years (IQR, 17.6-30.0) for autograft cases. The estimated cumulative revision rate at 2 years was 4.1% (95% CI, 2.9%-5.9%) for allografts and 1.7% (95% CI, 1.3%-2.2%) for autografts. BPTB allografts had a significantly higher adjusted risk of revision than BPTB autografts (HR, 4.54; 95% CI, 3.03-6.79; P < .001). This higher risk of revision was consistent with all allograft processing methods when compared with autografts and was also consistently higher in patients with allografts regardless of age. When BPTB allograft tissue was used for ACLR, an overall 4.54 times adjusted higher risk of revision was observed compared with surgery performed with a BPTB autograft. Whether the tissue was irradiated with either high- or low-dose radiation, chemically processed, or not processed at

    Optic perineuritis is an uncommon inflammatory disorder that involves optic nerve sheath. Numerous case reports have been published on optic perineuritis in adults, the majority of whom had bilateral presentation. There are limited data on optic perineuritis occurring in pediatric patients. We report a teenager who presented with a unilateral sign that mimicked the presentation of optic neuritis. The orbit and brain magnetic resonance imaging confirmed features of unilateral optic perineuritis. She was treated with a high dose of corticosteroids for 2weeks, and her final visual outcome was satisfactory. No signs of relapse were noted during follow-up visits.

    Laryngeal framework surgery is the current gold standard treatment for unilateral vocal fold paralysis. It provides a permanent solution to glottic insufficiency caused by injury to the recurrent laryngeal nerve. Various modifications to the original Isshiki type I laryngoplasty procedure have been described to improve voice and swallowing outcomes. The success of this procedure is highly dependent on the experience of the surgeon as it epitomizes the intersection of art and science in the field. The following article reviews the evidence, controversies, and complications related to laryngoplasty for unilateral vocal fold paralysis. It also provides a detailed analysis of how and when arytenoid-positioning procedures should be considered, and summarizes the literature on postoperative outcomes. PMID:24883239

    We present an unusual case of persistent generalized electroencephalography (EEG) suppression and right-sided clonic seizures in a male infant born at 40(+2) weeks\\' gestation, birthweight 3240g, with an isolated unilateral thalamic stroke. The EEG at 13 hours after birth showed a generalized very low amplitude background pattern, which progressed to frequent electrographic seizures over the left hemisphere. The interictal background EEG pattern remained grossly abnormal over the next 48 hours, showing very low background amplitudes (<10μV). Magnetic resonance imaging revealed an isolated acute left-sided thalamic infarction. This is the first description of severe global EEG suppression caused by an isolated unilateral thalamic stroke and supports the role of the thalamus as the control centre for cortical electrical activity.

    Given the bleak prospects for a global agreement on mitigating climate change, pressure for unilateral abatement is increasing. A major challenge is emissions leakage. Border carbon adjustments and output-based allocation of emissions allowances can increase effectiveness of unilateral action but introduce distortions of their own. We assess antileakage measures as a function of abatement coalition size. We first develop a partial equilibrium analytical framework to see how these instruments affect emissions within and outside the coalition. We then employ a computable general equilibrium model of international trade and energy use to assess the strategies as the coalition grows. We find that full border adjustments rank first in global cost-effectiveness, followed by import tariffs and output-based rebates. The differences across measures and their overall appeal decline as the abatement coalition grows. In terms of cost, the coalition countries prefer border carbon adjustments; countries outside the coalition prefer output-based rebates.(Author)

  10. Analysis of a Unilateral Contact Problem with Normal Compliance

    Full Text Available The paper deals with the study of a quasistatic unilateral contact problem between a nonlinear elastic body and a foundation. The contact is modelled with a normal compliance condition associated to unilateral constraint and the Coulomb's friction law. The adhesion between contact surfaces is taken into account and is modelled with a surface variable, the bonding field, whose evolution is described by a first-order differential equation. We establish a variational formulation of the mechanical problem and prove an existence and uniqueness result in the case where the coefficient of friction is bounded by a certain constant. The technique of the proof is based on arguments of time-dependent variational inequalities, differential equations and fixed-point theorem.

    Full Text Available It is known that early sensory deprivation modifies brain functional structure and connectivity. The aim of the present study was to investigate the neuro-functional organization of reading in a patient with profound congenital unilateral deafness. Using event-related potentials (ERPs, we compared cortical networks supporting the processing of written words in patient RA (completely deaf in the right ear since birth and in a group of control volunteers. We found that congenital unilateral hearing deprivation modifies neural mechanisms of word reading. Indeed, while written word processing was left-lateralized in controls, we found a strong right lateralization of the fusiform and inferior occipital gyri activation in RA. This finding goes in the same direction of recent proposals that the ventral occipito-temporal activity in word reading seem to lateralize to the same hemisphere as the one involved in spoken language processing.

    Full Text Available Darier disease is an autosomal-dominant disorder of keratin production which leads to a loss in epithelial adhesion and abnormal keratinization. The clinical correspondence is keratotic papules grouped in sebaceous areas of trunk, scalp, forehead and flexures. It is a rare disease and the variant focused on here of unilateral segmental distribution following the lines of Blaschko is rarer still, considering the fact that this presentation counts for only 10% of this already uncommom disease and with only 40 cases being reported in English medical literature. Mutation in this gene is expressed in the skin and brain. The treatment of Darier disease can be challenging and is often difficult and sometimes unsatisfactory. Systemic retinoids are considered the drug of choice for treating Darier disease. However, their use is limited by potential side effects. We described the case a metalworker male with unilateral segmental Darier disease following Blaschko lines and we review the literature on this subject.

    Full Text Available No abstract available. Article truncated after 150 words. An 85 year old woman with a history of COPD presented to the emergency department (ED with shortness of breath and cyanosis of her fingers. Her symptoms have been waxing and waning since she recovered from pneumonia a year ago. A week prior to admission, she visited an outpatient clinic for worsening cough, which was treated with levofloxacin, however her shortness of breath and cyanosis persisted. O2 saturation with 4 L oxygen was 85% and CT chest without contrast showed unilateral diaphragmatic paralysis with basilar atelectasis (Figure 1. She has no history of cardiac surgery, poliomyelitis or cervical spondylosis. Also, no cervical or lung mass was found on CT scan. Her diaphragmatic paralysis is most likely secondary to phrenic nerve injury. Unilateral diaphragmatic paralysis is usually asymptomatic and does not require treatment in most of cases. However, patients with underlying lung disease can present with shortness of breath and cyanosis …

    Aberrant movement strategies are characteristic of ACL-deficient athletes with recurrent knee instability (non-copers), and may instigate premature or accelerate joint degradation. Biomechanical evaluation of kinematic changes over time may elucidate noncopers’ responses to neuromuscular intervention and ACL reconstruction (ACLR). Forty noncopers were randomized into a perturbation group or a strength training only group. We evaluated the effects of perturbation training, and then gender on knee angle and tibial position during a unilateral standing task before and after ACLR. No statistically significant interactions were found. Before surgery, the strength training only group demonstrated knee angle asymmetry, but 6 months after ACLR, both groups presented with similar knee flexion between limbs. Aberrant and asymmetrical tibial position was found only in females following injury and ACLR. Neither treatment group showed distinct unilateral standing strategies following intervention; however, males and female noncopers appear to respond uniquely to physical therapy and surgery.

    The calcification of knee ligaments is a finding noted only in a handful of case reports. The finding of an anterior cruciate ligament calcification has been reported once in the literature. Comparable studies involving the posterior cruciate ligament, medial collateral ligament and an ossicle within the anterior cruciate ligament are likewise discussed in reports of symptomatic patients. We report a case of incidentally discovered anterior cruciate ligament calcification. We discuss the likely etiology and clinical implications of this finding.

    Full Text Available Hayate Nakagawa, Hidetaka Noma, Osamu Kotake, Ryosuke Motohashi, Kanako Yasuda, Masahiko Shimura Department of Ophthalmology, Tokyo Medical University Hachioji Medical Center, Tokyo, Japan Background: A few reports have described ocular complications of influenza A infection, such as impaired ocular movement, parasympathetic ocular nerve, keratitis, macular lesion, and frosted branch angiitis. We encountered a rare case of acute anterior uveitis and optic neuritis associated with influenza A infection. Case presentation: A 70-year-old man presented with symptoms of upper respiratory tract infection. A rapid diagnostic test showed a positive result for influenza A. At the same time, he developed ocular symptoms including blurred vision with optic disk edema and hemorrhage in the left eye, and bilateral red eyes. Multiplex polymerase chain reaction performed on aqueous humor sample detected no viral infection. Visual field testing with a Goldmann perimeter showed central and paracentral scotomas in the left eye. In addition to antiviral agent (oseltamivir phosphate 75 mg, the patient was prescribed topical prednisolone acetate ophthalmic suspension eye drops every 5 hours and high-dose intravenous methylprednisolone 1,000 mg daily for 3 days. Two months later, his best-corrected visual acuity improved to 20/50 with regression of visual field defects in his left eye. Conclusion: We report a case of bilateral acute anterior uveitis and unilateral optic neuritis concomitant with influenza A infection. Topical and systemic corticosteroids were effective to resolve acute anterior uveitis and neuritis. Analysis of aqueous humor sample suggested that acute anterior uveitis and optic neuritis in this case were not caused by influenza A virus infection per se but by autoimmune mechanism.

    OBJECTIVE Sagittal malalignment decreases patients' quality of life and may require surgical correction to achieve realignment goals. High-risk posterior-based osteotomy techniques are the current standard treatment for addressing sagittal malalignment. More recently, anterior lumbar interbody fusion, anterior column realignment (ALIF ACR) has been introduced as an alternative for correction of sagittal deformity. The objective of this paper was to report clinical and radiographic results for patients treated using the ALIF-ACR technique. METHODS A retrospective study of 39 patients treated with ALIF ACR was performed. Patient demographics, operative details, radiographic parameters, neurological assessments, outcome measures, and preoperative, postoperative, and mean 1-year follow-up complications were studied. RESULTS The patient population comprised 39 patients (27 females and 12 males) with a mean follow-up of 13.3 ± 4.7 months, mean age of 66.1 ± 11.6 years, and mean body mass index of 27.3 ± 6.2 kg/m 2 . The mean number of ALIF levels treated was 1.5 ± 0.5. Thirty-three (84.6%) of 39 patients underwent posterior spinal fixation and 33 (84.6%) of 39 underwent posterior column osteotomy, of which 20 (60.6%) of 33 procedures were performed at the level of the ALIF ACR. Pelvic tilt, sacral slope, and pelvic incidence were not statistically significantly different between the preoperative and postoperative periods and between the preoperative and 1-year follow-up periods (except for PT between the preoperative and 1-year follow-up, p = 0.018). Sagittal vertical axis, T-1 spinopelvic inclination, lumbar lordosis, pelvic incidence-lumbar lordosis mismatch, intradiscal angle, and motion segment angle all improved from the preoperative to postoperative period and the preoperative to 1-year follow-up (p < 0.05). The changes in motion segment angle and intradiscal angle achieved in the ALIF-ACR group without osteotomy compared with the ALIF-ACR group with osteotomy
