A 32-year-old man with a 16-year history of recurrent primary stabbing headache was admitted to our hospital, owing to mumps meningitis. On day 2 of admission, he began experiencing episodes of unbearable intermittent stabbing pain, each lasting few seconds, with conjunctival injection and tearing, on the temporal side of the left orbit. We suspected trigeminal autonomic cephalgias, and administered non-steroidal anti-inflammatory drugs (NSAIDs), oxygen, and sumatriptan; however, the pain episodes persisted. Subsequently, after the start of intravenous lidocaine administration, the pain episodes stopped. We diagnosed a short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), triggered by mumps meningitis. This is a valuable case report, involving a patient with a history of primary stabbing headache who was diagnosed with SUNCT triggered by mumps meningitis.

Stuttering is a developmental speech disorder that occurs in 5% of children with spontaneous remission in approximately 70% of cases. Previous imaging studies in adults with persistent stuttering found left white matter deficiencies and reversed right-left asymmetries compared to fluent controls. We hypothesized that similar differences might be present indicating brain development differences in children at risk of stuttering. Optimized voxel-based morphometry compared gray matter volume (GMV) and diffusion tensor imaging measured fractional anisotropy (FA) in white matter tracts in 3 groups: children with persistent stuttering, children recovered from stuttering, and fluent peers. Both the persistent stuttering and recovered groups had reduced GMV from normal in speech-relevant regions: the left inferior frontal gyrus and bilateral temporal regions. Reduced FA was found in the left white matter tracts underlying the motor regions for face and larynx in the persistent stuttering group. Contrary to previous findings in adults who stutter, no increases were found in the right hemisphere speech regions in stuttering or recovered children and no differences in right-left asymmetries. Instead, a risk for childhood stuttering was associated with deficiencies in left gray matter volume while reduced white matter integrity in the left hemisphere speech system was associated with persistent stuttering. Anatomical increases in right hemisphere structures previously found in adults who stutter may have resulted from a lifetime of stuttering. These findings point to the importance of considering the role of neuroplasticity during development when studying persistent forms of developmental disorders in adults.

Turner syndrome is well known to be associated with significant cardiovascular abnormalities. This paper studied the incidence of cardiovascular abnormalities in asymptomatic adolescent patients with Turner syndrome using multidetector computed tomography (MDCT) instead of echocardiography. Twenty subjects diagnosed with Turner syndrome who had no cardiac symptoms were included. Blood pressure and electrocardiography (ECG) was checked. Cardiovascular abnormalities were checked by MDCT. According to the ECG results, 11 had a prolonged QTc interval, 5 had a posterior fascicular block, 3 had a ventricular conduction disorder. MDCT revealed vascular abnormalities in 13 patients (65%). Three patients had an aberrant right subclavian artery, 2 had dilatation of left subclavian artery, and others had an aortic root dilatation, aortic diverticulum, and abnormal left vertebral artery. As for venous abnormalities, 3 patients had partial anomalous pulmonary venous return and 2 had a persistent left superior vena cava. This study found cardiovascular abnormalities in 65% of asymptomatic Turner syndrome patients using MDCT. Even though, there are no cardiac symptoms in Turner syndrome patients, a complete evaluation of the heart with echocardiography or MDCT at transition period to adults must be performed.

Synchronous Paget's disease of breast and vulva is extremely rare and has only been reported in the literature in one other case. A 58-year-old postmenopausal woman was found to have crusting, bleeding, and discharge from left nipple, as well as vulvar pruritis at the same time. Biopsy of breast lesion demonstrated Paget's disease with an underlying foci of ductal carcinoma in-situ that required total mastectomy of left breast with sentinel node biopsy and breast reconstruction. For vulvar symptoms, the patient was initially diagnosed with dermatitis and topical ointment was prescribed. However, her symptoms persisted for the next several months, and she underwent vulvar biopsy that demonstrated Paget's disease. She underwent partial vulvectomy. Multiple episodes of recurrent vulvar Paget's disease were noted in the postoperative course that medical therapy with Imiquimod and a second partial vulvectomy was performed. Synchronous of breast and vulvar Paget's disease is presented. There was a delay in diagnosing vulvar Paget's disease in this experienced case. While coincidence of breast and vulvar Paget's disease is likely, ectopic mammary tissue in vulvar as well as secondary metastasis from a focal lesion of breast Paget's disease needs to be carefully evaluated whenever the patient complains of vulvar symptoms in the setting of breast Paget's disease.

Wunderlich Syndrome (WS) is an uncommon condition where acute onset of spontaneous bleeding occurs into the subcapsular and perirenal spaces. It can prove fatal if not recognized and treated aggressively at the appropriate time. A 32-year-old male diagnosed elsewhere as acute renal failure presented with tender left loin mass, fever and hypovolemic shock with serum creatinine 8.4 mg/dl. He was started on higher antibiotics and initiated on haemodialysis. Ultrasonogram (USG), Non-Contrast Computed Tomography (NCCT) and Magnetic Resonance Imaging (MRI) showed bilateral perirenal subcapsular haematomas - right 3.6 x 3.1 cm and left 10.3 x 10.3 cm compressing and displacing left kidney, fed by capsular branch of left renal artery on CT angiogram. Initial aspirate was bloody but he persisted to have febrile spikes, renal failure and urosepsis and he was managed conservatively. Repeat NCCT 10 days later revealed left perinephric abscess and Percutaneous Drainage (PCD) was done. Patient improved, serum creatinine stabilized at 2 mg/dl without haemodialysis and PCD was removed after two weeks. To conclude, bilateral idiopathic spontaneous retroperitoneal haemorrhage with renal failure is a rare presentation. This case highlights the need for high index of suspicion, the role of repeated imaging and successful minimally invasive management with timely PCD and supportive care.

Background: Obstructive nephropathy is an uncommon side effect of sulfadiazine, which is used for the treatment of toxoplasmosis. We present a case of acute renal colic and urine extravasation of a patient shortly after she was started on this medication. Case Presentation: A 31-year-old female presented with acute renal colic 2 weeks after starting treatment with sulfadiazine and pyrimethamine for ocular toxoplasmosis. Results: A noncontrast computed tomography revealed left hydronephrosis and fluid located around the kidney and in the left gutter. There were no urinary stones. Administration of intravenous contrast revealed significant urine extravasation at the level of the ureteropelvic junction. Intravenous contrast injection confirmed that the extravasation consisted of urine leakage at the ureteropelvic junction. Her clinical condition improved with the insertion of an internal stent, which was left in place for 4 weeks. A retrograde pyelography performed at the time of the internal stent removal ruled out persistent extravasation and filling defects in the left upper urinary tract. Considering the clinical circumstances and the imaging results, it appears that this is a first reported case of sulfadiazine-induced obstructive uropathy associated with urine extravasation. Conclusion: Although rare, obstructive uropathy related to sulfadiazine medication should be promptly suspected, diagnosed, and treated. Patients should be instructed to substantially increase their liquid intake while on that medication.

An important number of patients with idiopathic dilated cardiomyopathy have dramatically improved left ventricular function with optimal treatment; however, little is known about the evolution and long-term outcome of this subgroup, which shows apparent healing. This study assesses whether real healing actually exists in dilated cardiomyopathy. Persistent apparent healing was evaluated among 408 patients with dilated cardiomyopathy receiving tailored medical treatment and followed over the very long-term. Persistent apparent healing was defined as left ventricular ejection fraction ≥50% and indexed left ventricular end-diastolic diameter ≤33 mm/m(2) at both mid-term (19±4 months) and long-term (103±9 months) follow-up. At mid-term, 63 of 408 patients (15%) were apparently healed; 38 (60%; 9%of the whole population) showed persistent apparent healing at long-term evaluation. No predictors of persistent apparent healing were found. Patients with persistent apparent healing showed better heart transplant–free survival at very long-term follow-up (95% versus 71%; P=0.014) compared with nonpersistently normalized patients. Nevertheless, in the very longterm, 37% of this subgroup experienced deterioration of left ventricular systolic function, and 5% died or had heart transplantation. Persistent long-term apparent healing was evident in a remarkable proportion of dilated cardiomyopathy patients receiving optimal medical treatment and was associated with stable normalization of main clinical and laboratory features. This condition can be characterized by a decline of left ventricular function over the very long term, highlighting the relevance of serial nd individualized follow-up in all patients with dilated cardiomyopathy, especially considering the absence of predictors for longterm apparent healing.

Persistent left superior vena cava is a common congenital anomaly of the thoracic venous system. Left superior vena cava draining into left atrium is a malformation of sinus venosus and caval system. The anomaly may be a cause of unexplained hypoxia even in adults. It may give rise to various diagnostic and technical challenges during cardiac catheterization and open-heart surgery. It is often detected serendipitously during diagnostic workup. Isolated left superior vena cava opening into left atrium is very commonly associated with other congenital heart defects. But tetralogy of Fallot is very rarely associated with persistent left superior vena cava which drains into left atrium. We report four such cases who underwent surgical correction successfully.

Examination revealed a draining sinus tract in the buccal vestibule of the maxilla in the left anterior segment and expansion in the middle of palate. On conventional radiographic examination the lesion was initially assumed to be a periapical problem related to the incisors but subsequently it was diagnosed to be a bisphosphonate osteonecrosis. Acquiring a comprehensive medical history from the patients, conducting the clinical vitality tests and most importantly being familiar with the non-odontogenic lesions that can be side effects of specific medications are important requirements for reaching a correct diagnosis.

BACKGROUND: Despite the existence of efficacious medications, many patients in actual practice remain with uncontrolled hypertension. Randomized clinical trials, cannot address this issue well given their highly restricted environment. This paper examines persistence with antihypertensive therapy among patients in actual practice. METHODS: Cohort study of patients who received a diagnosis of hypertension and were treated between 1989 and 1994 identified through the Saskatchewan Health databases. Patients with concurrent diagnoses likely to affect initial treatment choice were excluded. The resulting population of 79,591 subjects was grouped into those with established hypertension (52,227 [66%]) and those with newly diagnosed hypertension (27,364 [34%]). The initial antihypertensive prescription, subsequent changes in treatment and persistence with antihypertensive therapy were analysed. RESULTS: Persistence with antihypertensive therapy decreased in the first 6 months after treatment was started and continued to decline over the next 4 years. Of the patients with newly diagnosed hypertension, only 78% persisted with therapy at the end of 1 year, as compared with 97% of the patients with established hypertension (p < 0.001). Among those with newly diagnosed hypertension, older patients were more likely than younger ones to persist, and women were more likely than men to persist (p < 0.001). INTERPRETATION: This analysis of actual practice data indicates that barriers to persistence occur early in the therapeutic course and that achieving successful therapy when treatment is started is important to maintaining long-term persistence.

Avascular necrosis occur as a result of diverse etiology. Chronic inflammatory conditions such as systemic lupus erythematosus considered as a recognize cause. Many cases were reported in systemic lupus erythematosus after treating with corticosteroids. We report a case of a corticosteroid naïve patient presented as bilateral avascular necrosis of femoral head and later progressed to a case of systemic lupus erythematosus. A 26 year old lady presented with right sided hip pain and diagnosed as avascular necrosis of the femoral head. After 6 months she presented a similar pain in left hip, which revealed avascular necrosis of left femoral head as well. A probable cause for her clinical presentation could not be found after extensive clinical and laboratory evaluation. Patient reported high erythrocyte sedimentation rate persistently, and over the next few years progressed as a case of systemic lupus erythematosus. Above case illustrated avascular necrosis could be an early musculoskeletal manifestation of systemic lupus erythematosus even in the absence of corticosteroid administration.

Childhood meningiomas are scarce in clinical practice with an incidence ranging from 0.4 to 4.6% of all pediatric central nervous system (CNS) tumors. Cervico-occipital meningiomas account for 3.7% of childhood meningiomas and are slightly more frequent in male. A 5-year-old female presented with febrile posterior cervico-occipital pain for 3 weeks. She was diagnosed with meningitis and treated for a similar period with adapted antibiotics. The pain persisted even after treatment. Magnetic resonance imaging revealed an enhancing subdural extra medullary mass of the cervico occipital junction, developing around the left vertebral artery. The characteristics of the lesion were strongly suggestive of a neuroma. Surgical removal of the tumor aiming the decompression of the spinal cord and nerve roots was performed with a surprising discovery: The tumor was tightly attached to the dura at the entry of the left vertebral artery. The resection was total and only a thin part close to the artery was left. The pathological findings confirmed the diagnosis of meningothelial meningioma. Meningioma should be considered in the differential diagnosis of contrast enhancing subdural extra medullary lesions of the cervico-occipital junction in children.

Thyroid storm following radioactive iodine (RAI) therapy for pediatric graves disease.

Female, 11 FINAL DIAGNOSIS: Thyroid storm Symptoms: Diarrhea • tachycardia • tachypnea • tremor • wheezing - Clinical Procedure: - Specialty: - Rare disease. A growing number of pediatric endocrinologists treat Graves disease with radioactive iodine (RAI) therapy due to the typically definitive nature of I-131 therapy. Given the published benefits and perceived low risks of RAI when compared to surgery or long-term anti-thyroid medication, the trend towards therapy with RAI is likely to continue. Nevertheless, RAI is not without significant risk. An 11-year-old girl with newly diagnosed Graves disease received RAI for definitive treatment of her hyperthyroidism. Within 24 hours of receiving I-131, she developed increasing sleepiness and eventually became unresponsive. Upon arrival at the emergency department she had a tonic-clonic seizure and was diagnosed with thyroid storm. Despite best efforts to manage her hyperthyroidism, she suffered a stroke of the left cerebral hemisphere that left her with persistent neurological deficits. Although thyroid storm after thyroid ablation is rare, the significant morbidity and potential mortality of pediatric thyroid storm warrant further studies to determine if children with markedly elevated thyroid hormone concentrations at diagnosis should receive prolonged pretreatment with anti-thyroid drugs. While such an approach may reduce the efficacy of I-131 ablation, it can also reduce and hopefully eliminate the risk of post-ablative thyroid storm.

Mitral regurgitation commonly improves after implantation of a left ventricular assist device without concomitant valvular repair owing to the mechanical unloading of the left ventricle. However, the development (or persistence) of significant mitral regurgitation after implantation of a left ventricular assist device is associated with adverse clinical events. We present a case of a left ventricular assist device patient who successfully underwent a percutaneous MitraClip procedure for repair of persistent late postoperative mitral insufficiency with demonstrable clinical and hemodynamic improvement.

Persistent left superior vena cava (PLSVC) is a congenital anomaly, that results when there is an absence of the normal regression of the left common precardinal vein during embryogenesis. Usually, this anomaly remains asymptomatic, however, when the PLSVC drains into the left atrium this could lead to a right-to-left shunt. Additionally, this can result in inadvertent delivery of air or thrombus into the systemic circulation with potential neurologic, cardiac and renal complications. In this article, we present a case of an extreme premature Mexican newborn in which the diagnosis was made after placement of a percutaneous central venues catheter.

Neural and behavioral associations of manipulated determination facial expressions.

Price, Tom F; Hortensius, Ruud; Harmon-Jones, Eddie

2013-09-01

Past research associated relative left frontal cortical activity with positive affect and approach motivation, or the urge to move toward a stimulus. Less work has examined relative left frontal activity and positive emotions ranging from low to high approach motivation, to test whether positive affects that differ in approach motivational intensity influence relative left frontal cortical activity. Participants in the present experiment adopted determination (high approach positive), satisfaction (low approach positive), or neutral facial expressions while electroencephalographic (EEG) activity was recorded. Next, participants completed a task measuring motivational persistence behavior and then they completed self-report emotion questionnaires. Determination compared to satisfaction and neutral facial expressions caused greater relative left frontal activity relative to baseline EEG recordings. Facial expressions did not directly influence task persistence. However, relative left frontal activity correlated positively with persistence on insolvable tasks in the determination condition. These results extend embodiment theories and motivational interpretations of relative left frontal activity. Published by Elsevier B.V.

Evaluation of left ventricular function by bedside ultrasound in acute toxic myocarditis.

Myocarditis can be difficult to diagnose in the Emergency Department (ED) due to the lack of classic symptoms and the wide variation in presentations. Poor cardiac contractility is a common finding in myocarditis and can be evaluated by bedside ultrasound. To demonstrate the utility of fractional shortening measurements as an estimation of left ventricular function during bedside cardiac ultrasound evaluation in the ED. A 54-year-old man presented to the ED complaining of 3 days of chest tightness, palpitations, and dyspnea, as well as persistent abdominal pain and vomiting. An electrocardiogram (ECG) showed sinus tachycardia with presumably new ST-segment elevation and signs of an incomplete right bundle branch block. A bedside echocardiogram was performed by the emergency physician that showed poor left ventricular function by endocardial fractional shortening measurements. On further questioning, the patient revealed that for the past 2 weeks he had been regularly huffing a commercially available compressed air duster. Based on these history and examination findings, the patient was given a presumptive diagnosis of toxic myocarditis. A follow-up echocardiogram approximately 7 weeks later demonstrated resolution of the left ventricular systolic dysfunction and his ECG findings normalized. Cardiac ultrasound findings of severely reduced global function measured by endocardial fractional shortening were seen in this patient and supported the diagnosis of myocarditis. Endocardial fractional shortening is a useful means of easily evaluating and documenting left ventricular function and can be performed at the bedside in the ED. Copyright © 2013 Elsevier Inc.

A 45 year-old-man was admitted to our hospital because of discomfort in his left scrotum. He had a left testicular tumor. We performed high orchiectomy and pathological findings revealed testicular cancer. He was treated with bleomycin, etoposide and cisplatin. Computed tomography showed a new mass in the left lung after 3 cycles of the chemotherapy. Because of its rapid growth, the tumor was thought to be a metastasis lesion of testicular cancer or pulmonary infection. Transbronchial lung biopsy showed an invasion of multinucleated giant cells and granuloma. The culture and polymerase chain reaction of the bronchial sputum were positive for myobacterium avium-complex (MAC). From these findings, the left lung tumor was diagnosed as pulmonary MAC disease. He received partial resection of the left lung and the lesion was diagnosed as granuloma. There was no recurrence of testicular cancer or pulmonary disease after the surgery.

We previously demonstrated the existence of a left-to-right atrial dominant frequency gradient during paroxysmal but not persistent atrial fibrillation (AF) in humans. One possible mechanism of the left-to-right dominant frequency gradient involves the role of the pulmonary veins (PVs) in AF maintenance. The purpose of this study was to examine the effect of PV isolation on the dominant frequency gradient and outcome after PV isolation. Patients with either paroxysmal or persistent AF were studied. Recordings were made from catheters in the coronary sinus (CS), posterior right atrium (RA), and posterior left atrium (LA) during AF before and after PV isolation. Mean left-to-right dominant frequency gradient was measured before and after segmental PV isolation. Patients were followed for AF recurrence after PV isolation. Twenty-seven patients with paroxysmal (n = 15) or persistent (n = 12) AF were studied. In the paroxysmal group, baseline dominant frequency was greatest in the posterior LA with a significant left-to-right atrial dominant frequency gradient (posterior LA = 6.2 +/- 0.9 Hz, CS = 5.8 +/- 0.8 Hz, posterior RA = 5.4 +/- 0.9 Hz; P <.001). After PV isolation, there was no regional difference in dominant frequency (5.9 +/- 0.7 Hz vs 5.7 +/- 0.6 Hz vs 5.7 +/- 0.7 Hz, respectively; P = NS). In the persistent AF group, there was no overall difference in dominant frequency among sites before or after PV isolation (P = NS); however, patients with long-term freedom from AF after PV isolation had a higher left-to-right dominant frequency gradient compared with patients with recurrent AF (0.4 vs 0.1 Hz; P <.05). PV isolation results in a loss in the left-to-right dominant frequency gradient in patients with paroxysmal AF. This finding supports the critical role of PVs in the maintenance of ongoing paroxysmal AF. Patients with persistent AF and a baseline left-to-right dominant frequency gradient have a better success rate with PV isolation alone compared with patients without a dominant frequency gradient.

Depression is common and associated with poor prognosis in acute coronary syndrome (ACS). There are few reports on the predictors of incident and persistent post-discharge depressive disorders in ACS. This study aimed to investigate the incidence and persistence of depressive disorder over a one year follow-up, and predictors of these outcomes. 1152 patients with recently developed ACS were recruited at baseline, and 828 were followed one year thereafter. Depressive disorder (major and minor) was diagnosed according to DSM-IV criteria, and analyzed according to baseline prevalence, and follow up incidence and persistence. Of 446 baseline participants with depressive disorders, 300 were randomized to a 24-week double blind trial of escitalopram or placebo, while the remaining 146 received medical treatment as usual. Associations of baseline socio-demographic and clinical characteristics with depressive disorder were investigated using logistic regression models. Two-week prevalence, and one-year incidence and persistence of depressive disorder were 38.7%, 13.1%, and 46.3%, respectively. Baseline depressive disorder was independently associated with female, lower educational level, previous ACS and higher heart rate. Incident depressive disorder was independently predicted by current unemployment, family history of depression, higher baseline Hamilton Depression Rating Scale(HAMD) score and lower left ventricular ejection fraction, and persistent depressive disorder by higher baseline HAMD score and the placebo or medical treatment as usual group in the 24-week trial. The generalizability should be considered since this study conducted in a single center. Depressive disorder in ACS patients is common and often persistent, and is associated with baseline characteristics and insufficient treatment. Appropriate detection and treatment of depressive disorder are clearly important in ACS patients. Copyright © 2015 Elsevier B.V. All rights reserved.

We present a case of neonatal ovarian torsion complicated by bowel obstruction and perforation and review the literature regarding the incidence of bowel obstruction in neonatal ovarian cysts, the presentation, and treatment. A term neonate was prenatally diagnosed with a cystic abdominal mass palpable on physical examination. A postnatal abdominal x-ray showed paucity of gas in the left hemiabdomen with rightward displacement of bowel loops. Exploratory laparotomy on day 2 of life revealed a large cystic mass in the left lower quadrant consistent with a torsed left ovary, an omental band causing strangulation of the bowel mesentery, and a perforation of the distal ileum. Our literature search revealed 19 reported cases of neonatal ovarian cysts resulting in bowel obstruction. Infants may present with a palpable abdominal mass, respiratory distress, as well as signs and symptoms of intestinal obstruction. Two mechanisms exist for bowel obstruction: adhesions caused by a torsed necrotic ovary and mass effect of a large ovarian cyst, often measuring 9 to 10 cm in diameter. Options to treat ovarian cysts include antenatal or postnatal aspiration, laparoscopy, and laparotomy. Cysts less than 4 to 5 cm can be observed, whereas operative intervention is indicated in symptomatic cases and in persistent or enlarging ovarian cysts. Copyright 2010 Elsevier Inc.

Sudden death may be the first manifestation of the Wolff-Parkinson-White syndrome, especially in children and adolescents. The aim of this study was to evaluate the usefulness of radiofrequency catheter ablation in children with Wolff-Parkinson-White syndrome with aborted sudden death. We report four patients with Wolff-Parkinson-White syndrome who survived cardiac arrest. The patients were aged from 2.5 months to 16 years. The two first patients were lactating infants; in the first sudden death occurred during digoxin treatment for supraventricular tachycardia secondary to Wolff-Parkinson-White syndrome and in the second the syndrome was diagnosed after an episode of sudden death. In these patients a free wall accessory pathway (left posterior and left lateral, respectively) was successfully ablated using a transseptal approach. The third patient was diagnosed with asymptomatic Wolff-Parkinson-White syndrome; sudden death occurred during exercise. In the fourth patient, sudden death occurred after intravenous therapy with adenosine triphosphate and amiodarone for rapid atrial fibrillation. In both patients, one accessory pathway, located in right posteroseptal and right anterior free wall, respectively, was ablated. After a mean follow-up of 43.5 26.4 months, no recurrence of sudden death had occurred and electrocardiogram showed sinus rhythm without delta wave. The third patient presented severe sequelae of hypoxemic encephalopathy, which persisted during the follow-up. Radiofrequency catheter ablation is the treatment of choice in Wolff-Parkinson-White syndrome with episodes of aborted sudden death.

We investigated the prevalence of pertussis in Korean adolescents and adults with persistent cough. Study population was adolescents (aged 11-20 yr) and adults (≥ 21 yr old) who showed persistent cough of 1-8 weeks' duration. Pertussis was diagnosed by culture, polymerase chain reaction (PCR), and serology. A total of 310 subjects participated in this study, and 76 cases (24.5%) met the criteria for laboratory-confirmed pertussis. The majority of the pertussis cases (66/76) were confirmed by serology, while 3 cases (1.0%) were diagnosed with culture, and 10 cases (3.2%) were detected with PCR. Of the 76 subjects diagnosed with pertussis, 20/86 cases were adolescents and 56/224 cases were adults. Neither adolescents nor adults received adolescent-adult booster against pertussis within the previous 5 yr. Pertussis can be a primary cause of persistent cough in Korean adolescents and adults.

It is unclear whether persistent prehypertension causes structural or functional alterations of the heart. We examined echocardiographic data of 1005 adults from a population-based survey at baseline in 1994/1995 and at follow-up in 2004/2005. We compared individuals who had either persistently normal (<120 mmHg systolic and <80 mmHg diastolic, n = 142) or prehypertensive blood pressure (120-139 mmHg or 80-89 mmHg, n = 119) at both examinations using multivariate regression modeling. Over 10 years, left ventricular end-diastolic diameters were stable and did not differ between the two groups. However, the prehypertensive blood pressure group displayed more pronounced ageing-related increases of left ventricular wall thickness (+4.7 versus +11.9%, P < 0.001) and left ventricular mass (+8.6 versus +15.7%, P = 0.006). Prehypertension was associated with a raised incidence of left ventricular concentric remodeling (adjusted odds ratio 10.7, 95% confidence interval 2.82-40.4) and left ventricular hypertrophy (adjusted odds ratio 5.33, 1.58-17.9). The ratio of early and late diastolic peak transmitral flow velocities (E/A) decreased by 7.7% in the normal blood pressure versus 15.7% in the prehypertensive blood pressure group (P = 0.003) and at follow-up the ratio of early diastolic peak transmitral flow and early diastolic peak myocardial relaxation velocities (E/EM) was higher (9.1 versus 8.5, P = 0.031) and left atrial size was larger (36.5 versus 35.3 mm, P = 0.024) in the prehypertensive blood pressure group. Finally, the adjusted odds ratio for incident diastolic dysfunction was 2.52 (1.01-6.31) for the prehypertensive blood pressure group. Persistent prehypertension accelerates the development of hypertrophy and diastolic dysfunction of the heart.

The majority of patients with partial anomalous drainage of pulmonary veins are asymptomatic during infancy and childhood. Patients with significant left-to-right shunt develop symptoms and benefit from early corrective surgery. Anomalous pulmonary veins draining into inferior vena cava is very rare and frequently encountered in association with scimitar syndrome. The purpose of this case report is to describe a non-scimitar patient with cor triatriatum who had anomalous dual drainage of right pulmonary veins into inferior vena cava/left atrium and anomalous connection of persistent left superior vena cava with a common pulmonary venous chamber. The patient underwent an operation with redirection of anomalous pulmonary venous drainage into left atrium and ligation of persistent left superior vena cava.

To investigate whether stability or changes in smoking predict disability pension (DP) due to low back diagnoses (LBD) and musculoskeletal diagnoses (MSD) after taking familial confounding into account using a co-twin design. Longitudinal smoking patterns and multiple covariates in a population-based cohort of 17,451 Finnish twins (6959 complete pairs) born before 1958 were surveyed through questionnaires in 1975 and 1981. The outcome data were collected from the national pension registers until the end of 2004. Cox proportional hazards regression models were used for statistical analyses. Disability pension due to low back diagnoses was granted to 408 individuals and disability pension due to musculoskeletal diagnoses to 1177 individuals during the follow-up of 23 years. Being a persistent smoker (current smoker both 1975 and 1981) predicted a significantly increased risk for disability pension (hazard ratio 1.69, 95% confidence interval 1.46, 1.97) compared to those individuals who had never smoked. The association remained when several confounding factors, including familial factors, were taken into account. Persistent smoking predicts early disability pension due to musculoskeletal diagnoses and low back diagnoses independently from numerous confounding factors, including familial effects shared by the co-twins. © 2013.

Differences in the prevalence of left and right congenital heart defects (CHD) across the United States are unclear. This study evaluated the overall prevalence and the distribution of right versus left CHD across US regions and divisions in neonates. Newborns born from 2000 to 2014 diagnosed with CHD were identified using the National Inpatient Sample. Heart defects were stratified into right, left, and "neither" subtypes. The risk of right and left heart diagnoses between US Census regions and divisions was compared using multivariable binomial regression, adjusting for infant, and hospital characteristics. Two hundred forty thousand four hundred fifty-five newborns were included and 38,185 (15.9%) were classifiable as having either right or left subtypes. Between 2000 and 2014, the prevalence of right defects increased from 1.65 to 2.88 cases/1,000 live born infants (p < .0001), left defects increased from 0.47 to 0.75 cases/1,000 live born infants (p < .0001), and "neither" defects increased from 10.82 to 20.09 cases/1,000 live born infants (p < .0001). Newborns in the Northeast (RD adj .03, 95% CI .02, .03), Midwest (RD adj .02, 95% CI .02, .03), and South (RD adj .02, 95% CI .02, .02) were significantly more likely to have a right heart defect diagnosis compared to the West. When stratified by division, New England states had a significantly higher prevalence of right defects compared to the Pacific (RD adj .09, 95% CI .06, 0.11). No differences in the prevalence of left defects were seen. The prevalence of CHD diagnoses at birth in the US has increased, and regional differences in the prevalence of right defects appear to exist. © 2017 Wiley Periodicals, Inc.

To systematically describe the imaging features and clinical correlates of a partial anomalous pulmonary venous connection diagnosed on computed tomography (CT) in adults. Twenty-nine adults with a partial anomalous pulmonary venous connection on CT were retrospectively identified. There were 19 women and 10 men, with a mean age of 53 (range: 19-83) years. Four cases were identified by review of 1825 consecutive chest CT reports from July 2000-July 2001, and 25 cases were culled from chest radiology teaching files at 3 institutions. Inclusion criteria were availability of CT images and medical charts. Chest radiographs (25 of 29 cases) were reviewed for mediastinal contour abnormalities, heart size, and pulmonary vascular pattern. Chest CT scans were reviewed for location, size, and drainage site of the anomalous vein; presence or absence of a pulmonary vein in the normal location; cardiac size and configuration; and pulmonary vasculature. Charts were reviewed for evidence of pulmonary and cardiovascular disease, history of congenital heart disease, and results of other cardiac imaging. The prevalence of a partial anomalous pulmonary venous connection was 0.2% (4 of 1825 chest CT reports). Seventy-nine percent (23 of 29 patients) had an anomalous left upper lobe vein connecting to a persistent left vertical vein, only 5% (1 of 23 patients) of whom had a left upper lobe vein in the normal location. Seventeen percent (5 of 29 patients) had an anomalous right upper lobe vein draining into the superior vena cava, 60% (3 of 5 patients) of whom also had a right upper lobe pulmonary vein in the normal location. One patient (3%) had an anomalous right lower lobe vein draining into the suprahepatic inferior vena cava. Chest radiographic findings were abnormal left mediastinal contour in 64% (15 of 25 patients), abnormal right mediastinal contour in 8% (2 of 25 patients), and cardiomegaly in 24% (6 of 25 patients). Computed tomography findings were cardiomegaly in 48% (14 of 29 patients), right atrial enlargement in 31% (9 of 29 patients), right ventricular enlargement in 31% (9 of 29 patients), and pulmonary artery enlargement in 14% (4 of 29 patients). Pulmonary or cardiovascular symptoms were present in 69% (20 of 29 patients), 55% (11 of 20 patients) of whom had specific alternative diagnoses (excluding congestive heart failure and pulmonary hypertension) to explain the symptoms. Only 1 patient (3%) was diagnosed with a secundum atrial septal defect. A partial anomalous pulmonary venous connection was seen in 0.2% of adults on CT. In contrast to previous series focusing on children, the anomalous vein in adults was most commonly from the left upper lobe, in women, and infrequently associated with atrial septal defects.

Why are some people left-handed? An evolutionary perspective

Llaurens, V.; Raymond, M.; Faurie, C.

Since prehistoric times, left-handed individuals have been ubiquitous in human populations, exhibiting geographical frequency variations. Evolutionary explanations have been proposed for the persistence of the handedness polymorphism. Left-handedness could be favoured by negative frequency-dependent selection. Data have suggested that left-handedness, as the rare hand preference, could represent an important strategic advantage in fighting interactions. However, the fact that left-handedness occurs at a low frequency indicates that some evolutionary costs could be associated with left-handedness. Overall, the evolutionary dynamics of this polymorphism are not fully understood. Here, we review the abundant literature available regarding the possible mechanisms and consequences of left-handedness. We point out that hand preference is heritable, and report how hand preference is influenced by genetic, hormonal, developmental and cultural factors. We review the available information on potential fitness costs and benefits acting as selective forces on the proportion of left-handers. Thus, evolutionary perspectives on the persistence of this polymorphism in humans are gathered for the first time, highlighting the necessity for an assessment of fitness differences between right- and left-handers.

A factor structure underlying DSM-IV diagnoses has been previously reported in neurologically intact patients. The authors determined the brain regions associated with factors underlying DSM-IV diagnoses and compared the ability of DSM-IV diagnoses, factor scores, and self-report measures to account for the neuroanatomical findings in patients with penetrating brain injuries. This prospective cohort study included 254 Vietnam War veterans: 199 with penetrating brain injuries and 55 matched control participants. Measures include DSM-IV diagnoses (from a Structured Clinical Interview for DSM), self-report measures of depression and anxiety, and CT scans. Factors underlying DSM-IV diagnoses were determined using an exploratory factor analysis and correlated with percent of brain regions affected. The ability of the factor scores, DSM-IV diagnoses, and the self-report psychiatric measures to account for the anatomical variance was compared with multiple regressions. Internalizing and externalizing factors were identified in these brain-injured patients. Damage to the left amygdala and bilateral basal ganglia was associated with lower internalizing factor scores, and damage to the left medial orbitofrontal cortex (OFC) with higher, and bilateral hippocampi with lower, externalizing factor scores. Factor scores best predicted left amygdala and bilateral hippocampal involvement, whereas DSM-IV diagnoses best predicted bilateral basal ganglia and left OFC involvement. Damage to the limbic areas involved in the processing of emotional and reward information, including structures involved in the National Institute of Mental Health's Research Domain Criteria Negative Valence Domain, influences the development of internalizing and externalizing psychiatric symptoms. Self-report measures underperformed DSM-IV and factor scores in predicting neuroanatomical findings.

Catheter ablation to achieve posterior left atrial wall (PW) isolation may be performed as an adjunct to pulmonary vein isolation (PVI) in patients with persistent atrial fibrillation (AF). We aimed to determine whether routine adenosine challenge for dormant posterior wall conduction improved long-term outcome. A total of 161 patients with persistent AF (mean age 59 ± 9 years, AF duration 6 ± 5 years) underwent catheter ablation involving circumferential PVI followed by PW isolation. Posterior left atrial wall isolation was performed with a roof and inferior wall line with the endpoint of bidirectional block. In 54 patients, adenosine 15 mg was sequentially administered to assess reconnection of the pulmonary veins and PW. Sites of transient reconnection were ablated and adenosine was repeated until no further reconnection was present. Holter monitoring was performed at 6 and 12 months to assess for arrhythmia recurrence. Posterior left atrial wall isolation was successfully achieved in 91% of 161 patients (procedure duration 191 ± 49 min, mean RF time 40 ± 19 min). Adenosine-induced reconnection of the PW was demonstrated in 17%. The single procedure freedom from recurrent atrial arrhythmia was superior in the adenosine challenge group (65%) vs. no adenosine challenge (40%, P < 0.01) at a mean follow-up of 19 ± 8 months. After multiple procedures, there was significantly improved freedom from AF between patients with vs. without adenosine PW challenge (85 vs. 65%, P = 0.01). Posterior left atrial wall isolation in addition to PVI is a readily achievable ablation strategy in patients with persistent AF. Routine adenosine challenge for dormant posterior wall conduction was associated with an improvement in the success of catheter ablation for persistent AF.

To analyze safety and efficacy of surgical totally endoscopic epimyocardial ablation in patients (pts) turned down for interventional catheter therapy due to long-standing persistent atrial fibrillation (pAF) combined with significant atrial dilatation (> 5 cm). Since December 2010, 15 pts were referred for surgical ablation due to persistent AF combined with biatrial dilatation (left atrium [LA] 5.0 ± 0.6 cm). Mean age was 52 ± 6 years, body mass index (BMI) 38 ± 6, duration of AF 2.8 ± 1.2 years, left ventricular end diastolic diameter (LVEDD) 5.8 cm ± 0.6 cm. Ablation was performed via a bilateral endoscopic approach using bipolar RF energy application. Monitoring was achieved by an event recorder (Reveal XT Medtronic, Inc., Minneapolis, MN, USA) or repeated 24-hours Holter electrocardiogram. All pts successfully received bilateral pulmonary vein isolation + box lesion + trigonal lesion + left atrial appendage resection. Mean duration of procedure was 235 ± 70 minutes. There was no intraoperative complication; however, one patient had persistent left phrenic nerve palsy. Mean hospital stay was 4 ± 2 days, mean follow-up time was 21 ± 11 months. Incidence of sinus rhythm (SR) was 67, 73, and 80% at discharge, three months, and 12 months follow-up. Mean LA diameter was reduced from 58.1 mm ± 6.0 mm preoperative to 49.7 mm ± 5.4 mm (p = 0.004) at 12 months follow-up. Incidence of SR was 86% at latest follow-up (mean time 21 months). All pts currently in SR (13/15 = 86%) are of class I or III antiarrhythmic drugs. Totally endoscopic left atrial ablation including left atrial resection can safely be performed. It achieved excellent rates of SR restoration in patients with long-standing persistent AF combined with significant atrial dilatation. © 2015 Wiley Periodicals, Inc.

Dysthymic disorder (DD) is a depressive disorder characterised by persistent low and/or irritable mood and has been identified as a major risk factor for developing major depressive disorder (MDD). MDD and DD have been associated with executive function difficulties of working memory and attention. Little is known about how executive function networks in the brain are affected in children and adolescents with MDD and even less in DD. This study used fMRI and two spatial working memory paradigms to investigate associated brain function in young people with DD and an age-, gender- and IQ- matched typically developing group. Nineteen male patients with DD (mean age 11.2±1.5 years) diagnosed according to DSM-IV criteria and 16 typically developing boys (mean age 10.5±1.1 years) performed a mental rotation and a delay-match to sample (DMTS) task while undergoing fMRI. All participants were medication-naïve at the time of testing. Compared to typically developing young people, the DD group showed less activation in left frontal regions including left ventro- and dorsolateral prefrontal cortices (PFC) during mental rotation. Medial frontal regions including dorsomedial PFC, anterior cingulate cortex and frontal pole also showed relatively reduced activation. During the DMTS task patients showed significantly more activation in the right precuneus and posterior cingulate cortex. This was a cross-sectional study with a small sample limiting the generalizability of the results. The results complement previous findings in adults with MDD that have shown differential activation of left PFC regions during working memory tasks. Additionally, altered function of cortical midline structures in young patients with DD was identified. This supports findings in children, adolescents and adults with MDD suggesting that the pathophysiology of depressive disorders extends to DD as a risk factor for MDD and exhibits continuity over the lifespan.

Abstract Introduction: Cerebral metastases are the most common form of central nervous system (CNS) tumours in adults. However, malignant neoplasm may also involve structures external to the brain, such as tissue surrounding the base of the skull, and then metastasize to the brain either by direct invasion or by spreading by the cranial nerves. CASE1: A 74 year-old man, with a past history of chronic kidney disease due to renal artery thrombosis and hypertension, was admitted in the emergency room (ER) complaining of persisting pain in the superior half of the right hemiface and frontal region, refractory to analgesia, with 2 months of evolution. He also referred diplopia in the right eye, homolateral hearing loss and asthenia. Neurological examination revealed psychomotor retardation, right VI cranial nerve paralysis, right sensorineural hypoacusis and dysphagia. Brain and neck MRI showed a lesion in right nasopharynx that invaded the bony structures of the base of the skull, in particular the petrous apex, clivus and great sphenoid wing. It also had an endocranial soft tissue component that occupied the cistern of Gasser’s ganglion. He was diagnosed with a nasopharynx malignant neoplasm. His clinical status deteriorated rapidly and he died 1 month later. CASE2: A 68 year-old woman, with a past history of left great sphenoid wing meningioma that was removed 2 years ago, was admitted in the ER complaining of tinnitus and hearing loss in the left ear and dizziness. Neurological examination revealed peripheral left facial paralysis, which the patient claims to have arisen shortly after the previous surgery and left conductive hypoacusis. Brain MRI showed a lesion in the left parotid gland that invaded the petrous bone, infiltrating the jugular foramen and carotid canal, causing deformation of these vascular structures. She was diagnosed with a parotid gland malignant neoplasm that slowly grow in the last 2 years. By this moment, she is still waiting for a decision about the best treatment plan. Conclusions: With this work, we intend to exemplify two cases in which two different soft tissue tumours slowly grow until they caused symptoms due to direct invasion of base of the skull structures, which significantly complicate their treatment and these patients’ survival.

Anaplastic transformation of differentiated thyroid carcinoma (DTC) is a rare event with a poor clinical outcome. It usually occurs in the primary site or in regional lymph nodes, but rarely in distant metastatic lesions. A 55-year-old woman with persistent pain in the left hip joint visited our hospital. She had a history of DTC that had been surgically removed 12 years earlier. Clinical images showed a tumorous mass in the left pelvis, indicative of bone metastasis. The patient underwent surgery to remove the tumor and remained stable until local recurrence was found 5 weeks after the surgery. The patient subsequently underwent radiation therapy; however, she died of respiratory failure due to lung metastases 2 months after the surgery for the recurrent lesion. The surgical specimens were diagnosed as anaplastic thyroid carcinoma, indicating that anaplastic transformation of thyroid follicular carcinoma occurred in the metastatic skeletal lesion. In addition, the patient had an unusually high white blood cell count throughout the course. Based on elevated serum granulocyte colony-stimulating factor (G-CSF) levels and positive immunostaining for G-CSF in the surgical specimens, the patient was diagnosed with paraneoplastic leukocytosis. To our knowledge, this is the first case of anaplastic transformation of DTC arising in a metastatic bone lesion described in the literature. In addition, the present case also exhibited severe leukocytosis accompanied by elevated serum G-CSF levels. Clinicians should be aware of the possibility of this occurring in their patients with DTC, as this development calls for a rapid change from observational follow-up to aggressive treatment.

Functional neuroimaging of sex differences in autobiographical memory recall in depression.

Young, K D; Bodurka, J; Drevets, W C

Females are more likely than males to develop major depressive disorder (MDD). The current study used fMRI to compare the neural correlates of autobiographical memory (AM) recall between males and females diagnosed with MDD. AM overgenerality is a persistent cognitive deficit in MDD, the magnitude of which is correlated with depressive severity only in females. Delineating the neurobiological correlates of this deficit may elucidate the nature of sex-differences in the diathesis for developing MDD. Participants included unmedicated males and females diagnosed with MDD (n = 20/group), and an age and sex matched healthy control group. AM recall in response to positive, negative, and neutral cue words was compared with a semantic memory task. The behavioral properties of AMs did not differ between MDD males and females. In contrast, main effects of sex on cerebral hemodynamic activity were observed in left dorsolateral prefrontal cortex and parahippocampal gyrus during recall of positive specific memories, and middle prefrontal cortex (mPFC), and precuneus during recall of negative specific memories. Moreover, main effects of diagnosis on regional hemodynamic activity were observed in left ventrolateral prefrontal cortex and mPFC during positive specific memory recall, and dorsal anterior cingulate cortex during negative specific memory recall. Sex × diagnosis interactions were evident in the dorsomedial prefrontal cortex, caudate, and precuneus during positive memory recall, and in the posterior cingulate cortex, insula, precuneus and thalamus during negative specific memory recall. The differential hemodynamic changes conceivably may reflect sex-specific cognitive strategies during recall of AMs irrespective of the phenomenological properties of those memories.

A 2-year-old neutered male European short-haired cat was presented for a persistent discharge from the scar of previous left eye enucleation, performed 6 months prior by the referring veterinarian. A surgical exploration of the orbit was performed and retained nictitating membrane glandular and conjunctival tissues were removed. Eleven days later, the cat developed an orbital pneumatosis caused by retrograde movement of air through a patent nasolacrimal system and diagnosed by survey radiographic examination of the skull. Nasolacrimal system patency was assessed by dacryocystography performed by injection of iodinated contrast medium under pressure into the orbital cavity. Computed tomography dacryocystography confirmed the radiographic findings. The condition resolved following dacryocystography, possibly as an inflammatory response to the contrast medium. To our knowledge, this is the first case of orbital pneumatosis reported in a cat. © 2013 American College of Veterinary Ophthalmologists.

Adiponectin is an adipocyte-derived protein with insulin-sensitizing and antiatherogenic properties. Failure to decrease blood pressure (BP) normally during night in hypertensive patients has been independently associated with left ventricular hypertrophy. We examined the relationship between adiponectin levels, insulin sensitivity, and left ventricular structure in 40 newly diagnosed never-treated patients with essential hypertension, including 20 patients with a normal night-time pressure decrease (ie, dippers) and 20 patients with BP persistently elevated throughout the 24-h period (ie, nondippers). All subjects had grade 1-2 hypertension, aged 18 to 65 years, no diabetes mellitus, no obesity, no hyperlipidemia, and no cardiopulmonary, renal, or hepatic disease. The two groups of patients were similar for age, sex, body mass index, and had no differences for clinic, 24-h, and diurnal BP, and 24-h, diurnal, and nocturnal heart rate, as well as glucose, total cholesterol, and triglyceride levels. Plasma insulin and homeostasis model assessment (HOMA index) were higher (P < .01), and adiponectin levels were lower (P < .005) in nondippers than in dippers. Adiponectin correlated inversely with HOMA index and insulin levels (r = -0.58, and r = -0.62, respectively, P < .001) in the entire population. Nondippers showed left ventricular mass, relative wall thickness, and measure of early and late diastolic peak flow velocity ratio similar to those of dippers. In the absence of major cardiovascular risk factors, nondipper essential hypertensive patients show more prominent insulin resistance and lower adiponectin compared to dippers. Therapeutic modulation of adiponectin or insulin resistance might provide additional benefit to the conventional antihypertensive treatment.

Mirror writing (MW) is a rare disorder in which a script runs in direction opposite to normal and individual letters are reversed. The disorder generally occurs after left-hemisphere lesions, is transient and is observed on the left hand, whereas usually motor impairments prevent assessment of direction of right handwriting. We describe a left-handed patient with complete left hand mirror writing, still evident 2 years after a hemorrhagic stroke in left nucleo-capsular region. Since the patient could write with his right hand he underwent several writing tasks with either hand, and a thorough assessment to clarify the nature of MW. MW was evident in writing to dictation with left hand only, both in right and left hemispace, but the patient could modify his behavior when a verbal instruction was provided. No mirror errors were found in reading words, in copying geometric figures and in spatial orientation tasks. MW in our patient could be accounted for by a failure in automatic transformation of grapho-motor programs to write with the left hand. A lack of concern (a sort of anosodiaphoria) and a poor cognitive flexibility could contribute to long-term persistence of MW. 2010 Elsevier Inc. All rights reserved.

Persistent left superior vena cava

Summary Persistent left superior vena cava (PLSVC) is the most common congenital malformation of thoracic venous return and is present in 0.3 to 0.5% of individuals in the general population. This heart specimen was dissected from a 35-yearold male cadaver whose cause of death was determined as non-cardiac. The heart was examined and we found a PLSVC draining into the coronary sinus. The right superior vena cava was present with a small-diameter ostium. An anomalous pulmonary vein pattern was observed; there was a common trunk to the left superior and left inferior pulmonary veins (diameter 17.8 mm) and an additional middle right pulmonary vein (diameter 2.7 mm) with two classic right pulmonary veins. The PLSVC draining into the coronary sinus had led to its enlargement, which could have altered the cardiac haemodynamics by significantly reducing the size of the left atrium and impeding its outflow via the mitral valve.

The majority of individuals with post-traumatic headache have symptoms that are indistinguishable from migraine. The overlap in symptoms amongst these individuals raises the question as to whether post-traumatic headache has a unique pathophysiology or if head trauma triggers migraine. The objective of this study was to compare brain structure in individuals with persistent post-traumatic headache (i.e. headache lasting at least 3 months following a traumatic brain injury) attributed to mild traumatic brain injury to that of individuals with migraine. Twenty-eight individuals with persistent post-traumatic headache attributed to mild traumatic brain injury and 28 individuals with migraine underwent brain magnetic resonance imaging on a 3 T scanner. Regional volumes, cortical thickness, surface area and curvature measurements were calculated from T1-weighted sequences and compared between subject groups using ANCOVA. MRI data from 28 healthy control subjects were used to interpret the differences in brain structure between migraine and persistent post-traumatic headache. Differences in regional volumes, cortical thickness, surface area and brain curvature were identified when comparing the group of individuals with persistent post-traumatic headache to the group with migraine. Structure was different between groups for regions within the right lateral orbitofrontal lobe, left caudal middle frontal lobe, left superior frontal lobe, left precuneus and right supramarginal gyrus (p < .05). Considering these regions only, there were differences between individuals with persistent post-traumatic headache and healthy controls within the right lateral orbitofrontal lobe, right supramarginal gyrus, and left superior frontal lobe and no differences when comparing the migraine cohort to healthy controls. In conclusion, persistent post-traumatic headache and migraine are associated with differences in brain structure, perhaps suggesting differences in their underlying pathophysiology. Additional studies are needed to further delineate similarities and differences in brain structure and function that are associated with post-traumatic headache and migraine and to determine their specificity for each of the headache types.

Immune thrombocytopenia (ITP) in children has a varied course and according to duration is distinguished as newly diagnosed (<3 months), persistent (3–12), and chronic (>12) types. Several studies have evaluated the prognostic factors for the progression of the disease, but similar works have yet to be performed in Greece. We aimed to identify prognostic markers for the three forms of the disease in 57 Greek children during a 13-year period. Information regarding age, gender, preceding infection, bleeding type, duration of symptoms and platelets at diagnosis, treatment, disease course, and immunological markers was recorded. 39 children had newly diagnosed, 4 persistent, and 14 chronic disease. Chronic ITP children were more likely to be of age > 10 years (p = 0.015) and have gradual initiation of the disease (p = 0.001), platelets > 10 × 109/L (p = 0.01), and impaired immunological markers (p < 0.003) compared to newly diagnosed/persistent groups. Recent history of infection was found mainly in the newly diagnosed/persistent group (p = 0.013). None of the children exhibited severe spontaneous bleeding. Conclusion. Even though ITP in children usually has a self-limited course, with rare serious bleeding complications, the chronic form of the disease is characterized by different predictive parameters, which can be used in clinical practice.

Aim of our study was to determine the dynamics of selected echocardiographic parameters after sinus rhythm (SR) restoration and maintenance in pts with persistent nonvalvular atrial fibrillation (AF) during one year follow-up period. Our study population comprised 104 pts (F/M 33/71; mean age 60.4 +/- 7.4) assigned to SR restoration and maintenance with serial antiarrhythmic drug usage, for whom transthoracic echocardiographic (TTE) variables were recorded prior to, 2 and 12 months after cardioversion (CD). Left ventricle diastolic diameter and fractional shortening were variables of interest. SR was presented in 66 (63.5%) pts at one year. There was no significant differences in left ventricle diastolic diameter during the follow up. A significant increase in left ventricular fractional shortening (29.9 +/- 6.9% vs 34.5 +/- 8.9%; p < 0.001) was found in pts assigned to the sinus rhythm restoration according to intention-to-treat analysis. Such trend was noted only in pts who maintained SR during the follow up (29.9 +/- 7.6% vs 35.6 +/- 9.3%; p < 0.001). Among all considered variables only value of left ventricular fractional shortening increased after successful CV of persistent AF in one year follow-up.

A 52-year-old Japanese woman was examined because of general malaise, weight loss and a lump in her left breast. She was diagnosed with cancer of the left breast and Graves' disease, and was administered methimazole (MMI). A left mastectomy was performed for the breast cancer. She presented with a high fever and peripheral blood examination revealed a severe pancytopenia. She was diagnosed with severe aplastic anemia, and administered G-CSF, however, the treatment was unsuccessful. Thus, oral methyprednisolone and cyclosporin were added. There was a remarkable improvement in the peripheral blood count.

Patients with chronic dizziness following traumatic head injury typically have multiple diagnoses involving combined peripheral and central vestibular dysfunction.

We hypothesised that chronic vestibular symptoms (CVS) of imbalance and dizziness post-traumatic head injury (THI) may relate to: (i) the occurrence of multiple simultaneous vestibular diagnoses including both peripheral and central vestibular dysfunction in individual patients increasing the chance of missed diagnoses and suboptimal treatment; (ii) an impaired response to vestibular rehabilitation since the central mechanisms that mediate rehabilitation related brain plasticity may themselves be disrupted. We report the results of a retrospective analysis of both the comprehensive clinical and vestibular laboratory testing of 20 consecutive THI patients with prominent and persisting vestibular symptoms still present at least 6months post THI. Individual THI patients typically had multiple vestibular diagnoses and unique to this group of vestibular patients, often displayed both peripheral and central vestibular dysfunction. Despite expert neuro-otological management, at two years 20% of patients still had persisting vestibular symptoms. In summary, chronic vestibular dysfunction in THI could relate to: (i) the presence of multiple vestibular diagnoses, increasing the risk of 'missed' vestibular diagnoses leading to persisting symptoms; (ii) the impact of brain trauma which may impair brain plasticity mediated repair mechanisms. Apart from alerting physicians to the potential for multiple vestibular diagnoses in THI, future work to identify the specific deficits in brain function mediating poor recovery from post-THI vestibular dysfunction could provide the rationale for developing new therapy for head injury patients whose vestibular symptoms are resistant to treatment.

A protocol was designed to diagnose the common malfunctions of a left ventricular assist device (LVAD). Mechanical circulatory support, primarily with an LVAD, is increasingly used for treatment of advanced heart failure (HF). Left ventricular assist device dysfunction is a recognized complication; but heretofore, a systematic method to accurately diagnose LVAD dysfunction has not been thoroughly described. We developed a catheter-based protocol designed to characterize a normally functioning LVAD and diagnose multiple types of dysfunction. A total of 15 studies of 10 patients supported with an LVAD were reviewed. All patients had been evaluated due to concerns regarding LVAD dysfunction. Of 15 examinations performed, 11 documented severe LVAD inflow valve regurgitation. One of these cases proved to have coexistent severe mitral valve regurgitation. One case was diagnosed with distortion of the LVAD outflow graft. One case of suspected embolization from the pumping chamber excluded the outflow graft as the source of emboli. One study had aortic insufficiency. As LVAD use for treatment of end-stage HF becomes widespread and durations of support are extended, dysfunction will be increasingly prevalent. This catheter-based protocol provided a practical method to diagnose multiple causes of LVAD dysfunction.

Anomalous left coronary artery from the pulmonary artery with a large patent ductus arteriosus: aversion of a catastrophe.

We present an infant who had an anomalous left coronary artery arising from the pulmonary artery (ALCAPA) and a large patent ductus arteriosus (PDA), who was diagnosed before a potentially catastrophic closure of PDA. In the presence of normal left ventricular function and the absence of coronary artery collaterals, it is difficult to diagnose ALCAPA. A disproportionate degree of left ventricular dilation and severity of mitral valve regurgitation relative to the degree of PDA shunt, and echogenic papillary muscles on an echocardiogram should raise a suspicion of coronary artery anomalies. The infant underwent surgical ligation of PDA with translocation of coronary arteries and had an uneventful recovery. © 2012 Wiley Periodicals, Inc.

Mycobacterium mageritense , a rapidly growing mycobacterium, is a rare clinical pathogen. Furthermore, parotitis due to non-tuberculosis mycobacterium is very rare in adults. Herein, we report the first case of M. mageritense parotitis in an immunocompetent adult. A 40-year-old man presented with swelling in a left parotid lesion. He was diagnosed with parotitis. The culture from the parotid abscess grew M. mageritense . He was unsuccessfully treated with levofloxacin monotherapy. Trimethoprim-sulfamethoxazole was added, leading to some clinical response; however, the erythema persisted despite 14 months of antibiotic therapy. Subsequently, the skin lesion was surgically removed. The antibiotic treatment was ceased a week after surgery as the postoperative course was uneventful and the lesion had improved. No recurrence was noted at 7 months after surgery. Although extremely rare, M. mageritense can cause parotitis in immunocompetent adults, and may not be sufficiently treated with antibiotics alone.

A child was admitted to our hospital for repair of a ventricular septal defect (VSD) characterized by a predominantly right-to-left shunt and a severe stenosis of the right ventricular outflow tract (Tetralogy of Fallot). Severe congenital anemia (hemoglobin 72 g/L), thrombocytopenia (42×G/L) and profound platelet dysfunction led a stem cell defect to be suspected. X-linked thrombocytopenia (GATA-1 mutation) was diagnosed. GATA-1 defect may complicate medical interventions due to excessive bleeding and partial or complete bone marrow failure. Maintaining a platelet count of 100 G/L and a maximal clot firmness (EXTEM-MCF) >50 mm allowed repair of the congenital heart defect without bleeding or hematological complications. Anemia and thrombocytopenia persisted after cardiac surgery, while the spontaneous bleeding tendency improved. © Georg Thieme Verlag KG Stuttgart · New York.

Charles Bonnet syndrome (CBS) is an uncommon disorder characterized by complex and recurrent visual hallucinations in patients with visual pathway pathologic defects. To describe a patient who experienced complex visual hallucinations following infarction in the right occipital lobe and epileptic seizure who was diagnosed as having CBS. A 65-year-old man presented acute ischemic stroke caused by artery to artery embolism involving the right occipital lobe. Following ischemic stroke, complex visual hallucinations in the left visual field not associated with loss of consciousness or delusion developed in the patient. Hallucinations persisted for >1 month and during hallucination, no electrographic seizures were recorded through 24 hours of videoelectroencephalographic monitoring. CBS may develop in a patient with occipital lobe infarction following an embolic event. CBS associated with medial occipital lobe infarction and epilepsy may coexist and reflects the abnormal functioning of an integrated neuronal network.

To evaluate the clinical course of orbital complication using a standardised diagnostic pathway. Seventy-three patients with orbital complications underwent a multimodal diagnostic pathway comprising ENT examination, leucocytes/CRP, CT-/MRI-scanning and disease-related data. Twenty-nine patients suffered from rhinosinusitis, 28 from mucoceles, 13 patients from neoplasms and three patients from rheumatic disorders. Clinical examination diagnosed 60 patients with eyelid swelling, 55 patients with ocular pain, 14 patients with diplopia, 4 patients with exophthalmus, 29 patients with visual field defect and 4 patients with visual loss. The diagnostic pathway identified acute rhinosinusitis with a sensitivity/specificity of 90 %/90 %, mucoceles with 79 %/100 %, neoplasms with 100 %/96 % and granulomatosis with polyangiitis with 100 %/100 %, respectively. All patients left the hospital in good general condition and with regular ocular motility; two patients suffered persistent visual loss. The standardised application of a widely accepted diagnostic pathway reliably distinguishes different causes of orbital complication.

Attention deficit/hyperactivity disorder (ADHD) is a heterogeneous behavioral disorder commonly found in children, with serious lifetime health and social consequences for both children and their parents. Public awareness of ADHD in Germany has increased in the past decade, but little is known about the costs of treating newly diagnosed patients in clinical practice. This study aimed to describe the resource utilization and treatment costs of patients aged 6 to 17 years with newly diagnosed ADHD, using patient data from a German sickness fund, and to quantify resource utilization by drug treatment and treatment persistence. To identify patients with newly diagnosed ADHD, the second largest German sickness fund was utilized. Complete claims data of all de-identified patients meeting eligibility criteria for 2007 and 2008 were extracted. Patients were divided into 1 of 3 treatment groups: drug treatment-persistent, drug treatment-nonpersistent, and nondrug treatment. The differences in costs and resource utilization are reported in a descriptive manner, with paired and unpaired 2-sample Wilcoxon tests used. Of 3407 newly diagnosed patients with ADHD, 1105 (32%) received an ADHD-specific drug following diagnosis; the remaining 2302 comprised the nondrug treatment group. Of the total number of drug-treated patients, 1-year observational data were available for only 786 methylphenidate users (71%). Of these, 503 patients (64%) comprised the drug treatment-persistent group (those having at least 1 prescription every 3 months during the 12 months following their first ADHD prescription) and 283 (36%) comprised the drug treatment-nonpersistent group. After excluding those patients with <12 months of follow-up, 1779 patients (52%) were included in the nondrug-treatment group. Outpatient visits and the number of drug prescriptions and associated costs were highest in the drug treatment-persistent group (P = 0.05); however, the number of hospital admissions and days spent in-hospital were lowest in this group. Significant average savings of €347/y in overall costs(P ¼ 0.05) were noted for the drug treatment–persistent group compared with the drug treatment–non persistent group. Nondrug-treated patients had €181/y lower costs (P ¼ 0.05) comparedtodrugtreatment-persistentgroup.Drugtreatment-nonpersistentpatientswerethemost expensive group [corrected]. These mean savings were €739/y and €552/y (drug treatment-persistent group and drug treatment-nonpersistent group, respectively) compared with nondrug-treated patients. There are potential cost-savings benefits when patients are treatment persistent compared to nonpersistent [corrected]. Therefore, future disease-management programs might consider treatment persistence as potentially reducing overall payer costs. Additionally, the clinical and psychosocial situations of patients and their families should be taken into account. Copyright © 2013. Published by EM Inc USA.

In 22 cases of left atrial isomerism studied at the Brompton Hospital, four cases were found to have an unusual arrangement of the abdominal vessels. There was persistence of an inferior caval vein, partially anomalous hepatic venous connection and additional continuation of part of the venous return from the lower body through the azygos venous system. This venous pattern had surgical implications in our index case, since redirection of the inferior caval venous return was necessary.

This study aimed to explore whether echocardiographic measurements during the early postoperative period can predict persistent left ventricular systolic dysfunction (LVSD) after aortic valve surgery in patients with chronic aortic regurgitation (AR). We prospectively recruited 54 patients (59 ± 12 years) with isolated chronic severe AR who subsequently underwent aortic valve surgery. Standard transthoracic echocardiography was performed before the operation, during the early postoperative period (≤2 weeks), and then 1 year after the surgery. Twelve patients with preoperative LVSD demonstrated LVSD at early after the surgery. Of the 42 patients without LVSD at preoperative echocardiography, 15 patients (36%) developed early postoperative LVSD after surgical correction. All 27 patients without LVSD at early postoperative echocardiography maintained LV function at 1 year after surgery. In the other 27 patients with postoperative LVSD, 17 patients recovered from LVSD and 10 patients did not at 1 year after surgery. Multiple logistic analysis demonstrated that postoperative left atrial volume index (LAVI) was the only independent predictor for persistent LVSD at 1 year after surgery in patients with postoperative LVSD (OR 1.180, 95% CI, 1.003-1.390, P = 0.046). The optimal LAVI cutoff value (>34.9 mL/m(2) ) had a sensitivity of 80% and a specificity of 88% for the prediction of persistent LVSD. Prevalence of early postoperative LVSD was relatively high, even in the patients without LVSD at preoperative echocardiography. Postoperative LAVI could be useful to predict persistent LVSD after aortic valve surgery in patients with early postoperative LVSD. © 2014, Wiley Periodicals, Inc.

Solid pseudopapillary tumor of the pancreas (SPTP) is a rare primary pancreatic tumor of an unknown etiology that is usually diagnosed in adolescent girls and young women. Most SPTPs are considered to be benign and only rarely metastasize. We report here on a 27-year old woman with recurrent SPTP with involvement of both the spleen and left kidney at the time of the initial diagnosis, and with aggressive behavior. In July 1995, she was admitted with abdominal discomfort and mass. She underwent exploratory laparotomy with distal pancrea tectomy, left nephrectomy and splenectomy, and was diagnosed with SPTP with invasion to both the spleen and left kidney. In June 2001, she again presented with abdominal pain and was diagnosed as having recurrence of the tumor. She underwent mass excision and omentectomy. Then she was lost to follow-up. In November 2005, she presented once again with an abdominal mass and was diagnosed with recurred SPTP, which formed a huge intraperitoneal mass with peritoneal seeding and the tumor showed multiple metastases in the liver. She is currently being treated conservatively. PMID:19771270

This study aimed to evaluate the left ventricular (LV) functions in a cohort of children with Graves' disease (GD). This is a cross-sectional case-control study. It included 36 children with GD and 36 healthy children matched for age and gender. Thyroid hormones (TSH, FT4, and FT3) and anti-thyroid autoantibodies [anti-thyroid peroxidase (anti-TPO), thyrotropin receptor (TRAbs), and thyroglobulin antibodies] were measured. Conventional and tissue Doppler imaging (TDI) echocardiographies were used to assess left ventricular systolic and diastolic functions. LV mass index (LVMI) and myocardial performance index (MPI) were also measured. Compared to healthy children, conventional echocardiography of patients with GD revealed higher LVMI (P = 0.001) indicating LV hypertrophy but normal LV functions while TDI revealed lower Em/Am ratio indicating LV diastolic dysfunction (P = 0.001). Significant correlations were reported between FT4 with LVMI (P = 0.05), Em/Am (P = 0.01), and MPI (P = 0.01). In multivariate analysis, a positive correlation was identified between FT4 with MPI (OR = 1.17; 95% CI = 1.09-1.15; P = 0.001). Children with newly diagnosed GD may have significant subclinical changes in LV structure and function (diastolic and global). TDI is more sensitive than conventional Doppler in detecting LV dysfunction. These findings highlight the importance of early monitoring of children with GD for left ventricular mass index and diastolic function. What is Known: • There is an increased risk for cardiac abnormalities in children with Graves' disease (GD). • Limited studies assessed left ventricular function in patients with GD. What is New: • Children with newly diagnosed GD may have significant subclinical changes in left ventricular structure and functions. • Children with newly diagnosed GD should be monitored for left ventricular mass index and diastolic function.

Persistent genital arousal disorder associated with functional hyperconnectivity of an epileptic focus.

Persistent Genital Arousal Disorder (PGAD) refers to the experience of persistent sensations of genital arousal that are felt to be unprovoked, intrusive and unrelieved by one or several orgasms. It is often mistaken for hypersexuality since PGAD often results in a high frequency of sexual behaviour. At present little is known with certainty about the etiology of this condition. We described a woman with typical PGAD symptoms and orgasmic seizures that we found to be related to a specific epileptic focus. We performed a EEG/MEG and fMRI spontaneous activity study during genital arousal symptoms and after the chronic administration of 300 mg/day of topiramate. From MEG data an epileptic focus was localized in the left posterior insular gyrus (LPIG). FMRI data evidenced that sexual excitation symptoms with PGAD could be correlated with an increased functional connectivity (FC) between different brain areas: LPIG (epileptic focus), left middle frontal gyrus, left inferior and superior temporal gyrus and left inferior parietal lobe. The reduction of the FC observed after antiepileptic therapy was more marked in the left than in the right hemisphere in agreement with the lateralization identified by MEG results. Treatment completely abolished PGAD symptoms and functional hyperconnectivity. The functional hyperconnectivity found in the neuronal network including the epileptic focus could suggest a possible central mechanism for PGAD. Copyright 2010 IBRO. Published by Elsevier Ltd.

To describe the development and implementation of an inpatient disease management program. Prospective observational study. On the basis of opportunities for improving quality or efficiency of inpatient and emergency department care, 4 diagnoses, including congestive heart failure (CHF), gastrointestinal hemorrhage, community-acquired pneumonia and sickle-cell crisis were selected for implementation of a disease management program. For each diagnosis, a task force assembled a disease management team led by a "physician champion" and nurse care manager and identified opportunities for improvement through medical literature review and interviews with caregivers. A limited number of disease-specific guidelines and corresponding interventions were selected with consensus of the team and disseminated to caregivers. Physician and nurse team leaders were actively involved in patient care to facilitate adherence to guidelines. For quarter 2 to 4 of 1997, there were improvements in angiotensin-converting enzyme inhibitor use, daily weight compliance, assessment of left ventricular function, hospital costs, and length of stay for care-managed patients with CHF. Differences in utilization-related outcomes persisted even after adjustment for severity of illness. For the other 3 diagnoses, the observational period was shorter (quarter 4 only), and hence preliminary data showed similar hospital costs and length of stay for care-managed and noncare-managed patients. An interdisciplinary approach to inpatient disease management resulted in substantial improvements in both quality and efficiency of care for patients with CHF. Additional data are needed to determine the program's impact on outcomes of other targeted diagnoses.

Persistence of the hyperplasic primordial vitreous body is determined by a deletion of embryonal development of the vitreous body and of the hyaloid vascular system. Infant aged 3.5 years presents persistence of primordial vitreous body with crystalline dislocation in the camera aquosa and secondary buphthalmos of the left eye and microphthalmos with dislocation of the crystalline in the vitreous body of the right eye. At the back of the right eye we noticed a whitish mass, richly vascularized with vestiges from the hyaloid artery, but the posterior half of the vitreous cavity is filled with microscopic blood; the fibrovascular membrane is made of conjunctive tissue set in parallel layers and vessels with macrolipophagic degeneration. Microscopic investigation of retina reveals glial hyperplasia zones in the neighbourhood of the vitreous body. In the present paper the authors show the persistence of the primordial vitreous body in the left eye and bilateral dislocation of the crystalline, revealing multiple ocular malformations.

Long-term consequences of traumatic experiences: an assessment of former political detainees in romania

PubMed Central

2005-01-01

Background Research has suggested that organized violence and torture have long-term psychological effects that persist throughout the lifespan. The present survey aimed at examining the prevalence of posttraumatic stress disorder (PTSD), and other disorders and symptoms, all present in old age, as long-term consequences of politically motivated violence in a comparison design. Methods A group of former political detainees (N = 59, mean age 73.5 years) who had been arrested by the Romanian communist regime were compared to an age- and gender-matched control group (N = 39). PTSD was assessed using a structured clinical interview (CIDI). The investigation of the clinical profile was further accomplished by self-rating measures for anxiety, depression, and health-related functioning, as well as by clinician-administrated interviews for substance abuse, dissociation, and somatization symptoms. Results Lifetime prevalence of PTSD was 54%. In the case of participants left untreated, PTSD persisted, often over four decades, such that current PTSD was diagnosed still in a third of the survivors. Other clinical conditions such as somatization, substance abuse, dissociative disorders, and major depression were also common among the former political detainees and often associated with current PTSD. Conclusion Our findings suggest that political detention may have long-term psychological consequences that outlast the changes in the political system. PMID:16185364

Surgical approach for persistent ductus arteriosus ligation is typically a left lateral thoracotomy opening the pleural-space with left lung retraction. We describe an alternative approach, with a minimally invasive anterior parasternal incision. This is particularly adapted to preterm infants weighing less than 1.5 kg. This approach ensures a good exposure of vessels. We believe that it is safe, reliable and reproducible. The learning curve should not be an issue for surgeons used to manage low weight patients.

To assess the ultrasonic characteristics of the criss-cross heart, and explore the value of echocardiography in the diagnosis of this rare congenital cardiac defect.

In all 4 patients, there was usual atrial arrangement, right hand ventricular topology, and concordant atrioventricular connections. The inlet components of the ventricular mass, however, crossed such that the apical component of the morphologically right ventricle was situated anteriorly and superiorly, and extended to the left relative to the apex of the morphologically left ventricle. The ventriculo-arterial connections were concordant in 1 patient, double outlet from the morphologically right ventricle in 2, and discordant in the other. In all 4 patients, it proved impossible to obtain the standard 4-chamber view showing simultaneously all four chambers and both atrioventricular valves. A series of apical 4-chamber or subcostal coronal views, obtained by tilting the transducer from posterior to anterior, demonstrate initially the connection of the left-sided left atrium and the right-sided left ventricle through the mitral valve. More anterior angulation of the transducer then showed the right-sided right atrium to be connected to the left-sided right ventricle through the tricuspid valve, confirming the presence of twisted atrioventricular connections. Color Doppler imaging displayed the crossing of the atrioventricular connections without mixing of the streams. Short-axis views across the ventricular mass confirmed that the right ventricle was superior, anterior, and to the left of the left ventricle, and demonstrated the horizontal position of the ventricular septum. When viewed subcostally, the distance between the tricuspid valve and the orifice of the inferior vena cava was significantly increased relative to normal findings. The echocardiographic findings were confirmed during surgical interventions in 3 patients, apart from the failure to diagnose one instance of persistent patency of the left superior vena cava. The failure to obtain a characteristic 4-chamber view in any cut was diagnostic for recognition of the criss-crossed atrioventricular junctions. Transthoracic echocardiography provides definitive images of this rare arrangement, and accurately defines the associated cardiac abnormalities. Copyright 2009. Published by Elsevier Ireland Ltd.

Indications and Use of the Gluten Contamination Elimination Diet for Patients with Non-Responsive Celiac Disease

2017-01-01

For the majority of patients diagnosed with celiac disease, once a gluten-free diet is initiated, symptoms improve within weeks and may completely resolve in months. However, up to 30% of patients may show signs, symptoms or persistent small intestinal damage after one year on a gluten-free diet. These patients require evaluation for other common GI etiologies and assessment of their celiac disease status in order to make a diagnosis and suggest treatment. Here, we propose an approach to evaluating patients with celiac disease with persistent symptoms, persistently elevated serology, and or persistent villous atrophy despite a gluten-free diet. We detail how to diagnose and distinguish between non-responsive and refractory celiac disease. Finally, we introduce the indications for use of the gluten contamination elimination diet and provide information for practitioners to implement the diet when necessary in their practice.

Fetomaternal alloimmune thrombocytopenia (FMAIT) caused by maternal antibodies is the leading cause of severe neonatal thrombocytopenia. A 1-month-old Caucasian girl was referred to our Hematology Clinic for persistent thrombocytopenia diagnosed after a bleeding episode. Diagnostic tests suggested FMAIT. Mild thrombocytopenia persisted for 18 months, and subsequent findings of dysmorphic facies, short stature and mild pulmonary stenosis led to the hypothesis of Noonan syndrome (NS), which was confirmed by genetic test. Other hematological abnormalities were excluded and she had no further bleeding episodes. This case illustrates the possibility of different diagnoses with the same clinical manifestations. The persistence of thrombocytopenia longer than expected associated with typical physical features led to the diagnosis of NS.

2001-06-01

A 3-mo-old male white Bengal tiger (Panthera tigris) presented with the chief complaint of regurgitation of solid food since weaning at 2 mo of age. Compared with its littermates, the tiger was in poor body condition and weighed only 10.3 kg when its littermates were estimated at 20-25 kg. Thoracic radiographs showed a megaesophagus cranial to the heart base. A contrast esophagram more clearly outlined the megaesophagus, and fluoroscopy demonstrated normal motility of the caudal esophagus. Endoscopic examination revealed a structure coursing dorsally from right to left over the esophagus and a constrictive band on the left of the esophagus at the heart base. Nonselective angiography confirmed the presence of a persistent right aortic arch, as well as an aberrant left subclavian artery. A left fourth intercostal thoracotomy was performed, and the ligamentum arteriosum was double ligated and divided. The left subclavian artery did not cause significant compromise of the esophagus and was not manipulated at surgery. The tiger recovered well from anesthesia and surgery. Solid food was slowly introduced over a 2-mo period without any regurgitation. The cub gained weight rapidly after surgery.

Isolated right superior vena cava drainage into the left atrium is an extremely rare cardiac anomaly, especially in the absence of other cardiac abnormalities. Only 28 of 5,127 reported consecutive congenital cardiac cases involved superior vena cava drainage into the left atrium, and all were associated with other cardiac anomalies. Of 19 reported cases of right superior vena cava drainage into the left atrium, most patients have been children who were experiencing mild hypoxemia and cyanosis. Herein, we describe the case of a 34-year-old woman who presented with asymptomatic hypoxemia in the peripartum period. She was diagnosed to have isolated drainage of the right superior vena cava into the left atrium. To the best of our knowledge, this is the 1st reported instance of such diagnosis by use of noninvasive imaging only, without cardiac catheterization. We also review the medical literature that pertains to our patient's anomaly. PMID:20069093

Abstract Rationale: Left atrial appendage aneurysms (LAAA) are rare. Patients with LAAA are often diagnosed incidentally or after cardiac tachyarrhythmia or systemic thromboembolism happen. Early diagnosis and surgical resection is of utmost importance to prevent hazardous adverse events. Patient concerns: We present a case of 46-year-old man with congenital LAAA. The individual in this manuscript has given written informed consent to publish these case details. Diagnoses: Imaging studies, such as echocardiography, cardiovascular computed tomography (CT) and magnetic resonance imaging (MRI), demonstrated the large cavity arising from the left atrial appendage. The diagnosis of LAAA was confirmed. Interventions: The patient underwent an aneurysmectomy without any complications. Outcomes: TTE confirmed the disappearance of the LAAA from the left parasternal short-axis view of the aortic root postoperatively. The patient remained asymptomatic without any adverse events at his 3-month follow-up visits. Lessons: The associated high risk of life-threatening complications and the relative ease of surgical removal suggest that prompt evaluation should be considered in patients with lesions adjacent to the left heart border.

Patient 1 was a 54-year-old female diagnosed with anomalous systemic arterial supply to normal basal segments of the left lung discovered as an abnormality on chest X-ray radiography. Patient 2 was a 47-year-old male in whom the disease was diagnosed by close examination of bloody sputum. Division of the abnormal artery and left lower lobectomy were performed in patient 1. Arterial congestion and serpentine distribution were noted in the basal segments of the lung, which was the region perfused by the abnormal artery, on histopathological examination. Arteriosclerotic changes were noted in the vascular wall, but no abnormal vascular wall or alveolar structure was noted in S6, which was not included in theperfused region. Based on the above findings, division of the abnormal artery and left basal segmentectomy were performed in patient 2. Bloody sputum disappeared, and activity of daily living( ADL) were not impaired after surgery.

High incidence of echocardiographic abnormalities of the interatrial septum in patients undergoing ablation for atrial fibrillation.

Atrial fibrosis or fatty deposition is known to increase the propensity for the development of atrial fibrillation (AF). Apart from the pulmonic veins, the interatrial septum (IAS) might play a role in the maintenance of AF. In contrast to left atrial anatomy and adjacent veins, the IAS cannot be visualized in detail with computed tomography. Thus, preprocedural transesophageal echocardiography (TEE) may provide important morphologic information beyond exclusion from atrial thrombi. The study comprised 108 consecutive patients (mean age 60 ± 11 years; 98 men). AF was paroxysmal in 91 (84%) and persistent in 17 (16%) patients. We investigated the morphological characteristics of the IAS by TEE in patients who underwent radiofrequency ablation of AF. The IAS was structurally abnormal in 46 (43%) patients, showing the following echocardiograhic findings: atrial septal hypermobility or aneurysm (n = 27) associated with a patent foramen ovale (PFO) (n = 11) or with a small atrial septal defect (ASD) (n = 2), a septal flap associated with a PFO or an ASD (n = 8), and an abnormally thickened IAS (n = 12). A thrombus in the left atrial appendage was discovered in only 2 (2%) patients. A structurally abnormal IAS was diagnosed in nearly half of the patients undergoing ablation therapy for AF. The information obtained by TEE is mandatory to exclude left atrial thrombi prior the ablation procedure. Moreover, detailed knowledge of morphologic characteristics of the IAS facilitates an optimized and safe performance of the transseptal puncture using long sheaths with large diameters. © 2012, Wiley Periodicals, Inc.

Behavioral evidence for multicomponent trail pheromone in the termite,Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae).

Evidence is presented for a multicomponent trail pheromone in the eastern subterranean termiteReticulitermes flavipes (Kollar). Choice tests were used to compare strength and persistency of trails made by termites in glass tubes. Tubes connected to termite nests for 24 hr were marked by termites with an extremely long-lasting chemical that persisted for at least one year, and a highly volatile substance that decayed in 15 min. Individual termites varied the trail they deposited under different circumstances. When removed from the nest and placed in a clean tube, they deposited a highly volatile substance. They left stronger and more persistent trails when exploring clean tubes attached to the nest. When they discovered a new food source, they left trails that were more attractive and far more persistent than trails made by exploring or displaced termites. A food trail made by 15 workers was still effective after 24 hr, whereas a trail made by 50 displaced workers, walking one after another through a tube, lasted only 5 min.

The protracted and highly variable development of prefrontal cortex regions that support cognitive control has been purported to shape the adult outcome of attention-deficit/hyperactivity disorder (ADHD). This neurodevelopmental model was tested in a prospectively followed sample of 27 adult probands who were diagnosed with ADHD in childhood and 28 carefully matched comparison subjects aged 21 – 28 years. Probands were classified with persistent ADHD or remitted ADHD. Behavioral and neural responses to the stimulus and response conflict task performed during functional magnetic resonance imaging were compared in probands and comparison subjects and in probands with persistent and remitted ADHD. Response speed and accuracy for stimulus, response, and combined conflicts did not differ across groups. Orbitofrontal, inferior frontal and parietal activation was lower in probands than comparison subjects, but only for combined conflicts, when demand for cognitive control was highest. Reduced activation for combined conflicts in probands was almost wholly attributable to the persistence of ADHD; orbitofrontal, inferior frontal, anterior cingulate and parietal activation was lower in probands with persistent ADHD than both probands with remitted ADHD and comparison subjects, but did not differ between probands with remitted ADHD and comparison subjects. These data provide the first evidence that prefrontal and parietal activation during cognitive control parallels the adult outcome of ADHD diagnosed in childhood, with persistence of symptoms linked to reduced activation and symptom recovery associated with activation indistinguishable from adults with no history of ADHD.

Extrinsic compression of the left atrium by the esophagus, the stomach, or both is an uncommon but important cause of hemodynamic compromise. Achalasia is a motility disorder characterized by impaired relaxation of the lower esophageal sphincter and dilatation of the distal two thirds of the esophagus. Echocardiographic imaging after oral ingestion of liquid containing carbon dioxide allowed for differentiation between a compressive vascular structure and the esophagus. We report a rare case of esophageal achalasia compressing the left atrium diagnosed by echocardiography using a liquid containing carbon dioxide in a 21-year-old woman with Turner syndrome.

We report the case of a patient stabilized under extra-corporeal membrane oxygenation after a refractory cardiogenic shock following myocardial infarction. Persistent left ventricular failure required secondary implantation of the left ventricular assist device (LVAD) HeartMate II. LVAD succeeded in the gradual recovery of myocardial contractility, allowing weaning of the device five months after implantation. Simultaneously, the patient beneficiated from coronary revascularization and resumed normal activity. This case emphasizes potential late recoveries after myocardial infarction complicated by left ventricular failure.

Increased functional connectivity between cortical hand areas and praxis network associated with training-related improvements in non-dominant hand precision drawing.

PubMed

Philip, Benjamin A; Frey, Scott H

2016-07-01

Chronic forced use of the non-dominant left hand yields substantial improvements in the precision and quality of writing and drawing. These changes may arise from increased access by the non-dominant (right) hemisphere to dominant (left) hemisphere mechanisms specialized for end-point precision control. To evaluate this prediction, 22 healthy right-handed adults underwent resting state functional connectivity (FC) MRI scans before and after 10 days of training on a left hand precision drawing task. 89% of participants significantly improved left hand speed, accuracy, and smoothness. Smoothness gains were specific to the trained left hand and persistent: 6 months after training, 71% of participants exhibited above-baseline movement smoothness. Contrary to expectations, we found no evidence of increased FC between right and left hemisphere hand areas. Instead, training-related improvements in left hand movement smoothness were associated with increased FC between both sensorimotor hand areas and a left-lateralized parieto-prefrontal network implicated in manual praxis. By contrast, skill retention at 6 months was predicted by changes including decreased FC between the representation of the trained left hand and bilateral sensorimotor, parietal, and premotor cortices, possibly reflecting consolidation and a disengagement of early learning processes. These data indicate that modest amounts of training (<200min total) can induce substantial, persistent improvements the precision and quality of non-dominant hand control in healthy adults, supported by strengthened connectivity between bilateral sensorimotor hand areas and a left-lateralized parieto-prefrontal praxis network.

To quantify the hemodynamic characteristics of patients with nonvalvular atrial fibrillation. Twenty patients with paroxysmal atrial fibrillation and 15 patients with persistent atrial fibrillation enrolled in this study,while 12 patients with sinus rhythms served as controls. The hemodynamic characteristics of the patients in left atrial appendage were measured by transesophageal echocardiography (TEE) and vector flow mapping (VFM) using indicators such as vectors,vortex and energy loss (EL). ① Significant differences appeared between the patients with atrial fibrillation and the controls in heart rate,size of left atrium,size of left atrial appendage (LAA),and velocities of LAA filling and emptying. ② Regular vectors in LAA in early systole and late diastole were found in the patients with paroxysmal atrial fibrillation and the controls; whereas,irregular vectors with direction alternating were visualized in the whole cardiac cycle in the patients with persistent atrial fibrillation. ③ Small vortexes were observed at the opening of the left atrial appendage in late diastole in the patients with paroxysmal atrial fibrillation and the controls. ④ Peak EL values occurred in early systole and late diastole in the patients with paroxysmal atrial fibrillation and the controls. But the patients with persistent atrial fibrillation had increased EL values over the whole cardiac cycle. VFM can visualize and quantify the hemodynamics of LAA in patients with different heart rhythms. It may provide a new method for assessing atrial fibrillation.

Our objective was to examine the effect of chronic treatment with amlodipine on blood pressure, left ventricular hypertrophy, and fibrosis in spontaneously hypertensive rats and the persistence of such an effect after drug withdrawal. We investigated the effects of treatment with 2, 8 and 20 mg/kg/day of amlodipine given orally for six months and at three months after drug withdrawal. Systolic blood pressure was measured using the tail-cuff method. At the end of the study period, the heart was excised, the left ventricle was isolated, and the left ventricle weight/body weight ratio was calculated as a left ventricular hypertrophy index. Fibrosis, expressed as collagen volume fraction, was evaluated using an automated image-analysis system on sections stained with Sirius red. Age-matched untreated Wistar-Kyoto and SHR were used as normotensive and hypertensive controls, respectively. Systolic blood pressure was reduced in the treated SHR in a dose-dependent way and after amlodipine withdrawal it increased progressively, without reaching the values of the hypertensive controls. Cardiac hypertrophy was reduced by 8 and 20 mg/kg/day amlodipine, but when treatment was withdrawn only the group treated with 8 mg/kg/day maintained significant differences versus the hypertensive controls. All three doses of amlodipine reduced cardiac fibrosis and this regression persisted with the two highest doses after three months without treatment. We concluded that antihypertensive treatment with amlodipine is accompanied by a reduction in left ventricular hypertrophy and regression in collagen deposition. Treatment was more effective in preventing fibrosis than in preventing ventricular hypertrophy after drug withdrawal. Copyright 2004 Elsevier Inc.

We report on a female patient with rheumatoid arthritis and end-stage renal-disease following AA-amyloidosis who presented with chest pain to the emergency department. ECG showed no signs of ischemia, echocardiography revealed a concentric left ventricular hypertrophy with increased texture. Serum concentration of troponin I was mildly elevated whereas creatine kinase (CK)/ CK-MB were normal. The chief complaints resolved spontaneously and there was no change in the serum troponin-I and CK/CK-MB concentrations. Coronary heart disease was ruled out by angiography and cardiac involvement of the underlying AA-amyloidosis was diagnosed. After one month, the patient suffered from a syncope complicated by a pelvic ring fracture with hemorrhagic shock and declined chronic dialysis treatment. Patients with end-stage renal disease may exhibit a persisting elevation of serum troponin concentration reflecting the high burden of cardiovascular disease. Myocardial infarction can be distinguished by the lack of increase in serial tests. Copyright Georg Thieme Verlag KG Stuttgart . New York.

We assessed the performance of PET/CT for diagnosis and management of infections in high-risk hematological cancer patients with persistent febrile neutropenia in a prospective study. (18)F-FDG PET/CT with contrast-enhanced CT was performed on day 5-7 of persistent fever. Between 2008 and 2011, 91 PET/CT examinations were performed for different episodes in 79 patients, resulting in 117 diagnoses. The sensitivity of the PET/CT was 79.8% (71/89) compared to 51.7% (46/89) with chest/sinus CT alone. Specificities were 32.14% (9/28) vs. 42.85% (12/28), respectively. PET/CT resulted in a change from the pre-test diagnosis in 63/91 (69%) of episodes and in modification of patients' management in 46/91 (55%). PET/CT was beneficial in diagnosing abdominal infections. PET/CT has a potential role in the diagnostic evaluation of patients with persistent febrile neutropenia. Copyright © 2013 Elsevier Ltd.

71-year-old woman with progressive left-sided, monocular diplopia and ptosis. Her symptoms mimicked ocular myasthenia, but she had an indirect carotid cavernous fistula (CCF). She was diagnosed with monocular myasthenia gravis (negative acetylcholinesterase antibody) after a positive ice test and started on Mestinon and underwent a thymectomy complicated by a brachial plexus injury. Months later, she developed left-sided proptosis and ocular bruit. She was urgently referred to neuro-interventional surgery and was diagnosed with an indirect high-flow left CCF, which was treated with Onyx liquid and platinum coil embolisation. Mestinon was discontinued. Her ophthalmic symptoms resolved. However, she was left with a residual left arm and hand hemiparesis and dysmetria secondary to a brachial plexus injury. Indirect CCF usually can present with subtle and progressive symptoms leading to delayed diagnosis or misdiagnosis. It is important for ophthalmologists to consider this differential in a patient with progressive ocular symptoms. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Anatomical considerations for the management of a left-sided superior caval vein draining to the roof of the left atrium.

Aims The pathophysiological entity of a persisting left-sided superior caval vein draining into the roof of the left atrium represents an extreme form of coronary sinus de-roofing. This is an uncommon, but well-documented condition associated with systemic desaturation due to a right-to-left shunt. Depending on the size of the coronary ostium, the defect may also present with right-sided volume loading. We describe two patients, both of whom presented with desaturation, and highlight the important anatomical features underscoring management. Methods and Results Both patients were managed interventionally with previous assessment of the size of the coronary sinus ostium through cross-sectional imaging. This revealed a restrictive interatrial communication at the right atrial mouth of the coronary sinus in both patients, which permitted an interventional approach, as the residual left-to-right shunt subsequent to closure of the aberrant vessel would be negligible. At intervention, test occlusion of the left superior caval vein allowed assessment of decompressing vessels before successful occlusion using an Amplatzer Vascular Plug. Persistence of a left superior caval vein draining to the left atrium may be associated with an interatrial communication at the mouth of the unroofed coronary sinus. The ostium of the de-roofed coronary sinus can be atretic, restrictive, normally sized, or enlarged. Careful assessment of the size of this defect is required before treatment. In view of its importance, which has received little attention in the literature to date, we suggest an additional consideration to the classification of unroofed coronary sinus.

Persistent developmental stuttering is characterized by speech production disfluency and affects 1% of adults. The degree of impairment varies widely across individuals and the neural mechanisms underlying the disorder and this variability remain poorly understood. Here we elucidate compensatory mechanisms related to this variability in impairment using whole-brain functional and white matter connectivity analyses in persistent developmental stuttering. We found that people who stutter had stronger functional connectivity between cerebellum and thalamus than people with fluent speech, while stutterers with the least severe symptoms had greater functional connectivity between left cerebellum and left orbitofrontal cortex (OFC). Additionally, people who stutter had decreased functional and white matter connectivity among the perisylvian auditory, motor, and speech planning regions compared to typical speakers, but greater functional connectivity between the right basal ganglia and bilateral temporal auditory regions. Structurally, disfluency ratings were negatively correlated with white matter connections to left perisylvian regions and to the brain stem. Overall, we found increased connectivity among subcortical and reward network structures in people who stutter compared to controls. These connections were negatively correlated with stuttering severity, suggesting the involvement of cerebellum and OFC may underlie successful compensatory mechanisms by more fluent stutterers.

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

We report a case of persistence of the 5th aortic arch associated with total interruption of the aortic arch. This clinical case shows the diagnostic pitfall of the persistence of the 5th aortic arch and its beneficial hemodynamic effect. Preoperative clinical picture was misleading, due to the persistence of femoral pulses and clinical signs of left-to-right shunt via a wide ductus arteriosus. The diagnosis was intraoperatively adjusted on the basis of blood pressure monitoring using catheter placed into the femoral artery.

Association of brain abscess with a mycotic aneurysm of the contralateral internal carotid artery in a patient of cyanotic heart disease

Bansal, Sumit; Borkar, Sachin A.; Mahapatra, Ashok K.

2017-01-01

Congenital cyanotic heart disease can lead to intra-cranial involvement. Authors report a very rare case of right intra-cerebral abscess diagnosed on computerized tomography (CT) scan and simultaneous presence of an aneurysm of the left internal carotid artery diagnosed on CT angiogram in a 15-year-old child with congenital cyanotic heart disease with recent onset left hemiparesis. Right cerebral abscess was tapped and left internal carotid aneurysm was planned to be followed up by giving antibiotics and serial angiograms, but he could not survive and died due to non-cranial cause. We conclude that cerebral angiography is necessary to diagnose cerebro-vascular complications, including infectious aneurysms, in cases presenting with unusual findings on neuroimaging study. Patient must undergo serial angiography while being on intravenous antibiotics. Intervention (either surgical or endovascular) should be considered if there are no signs of regression of size of aneurysm or in the presence of aneurysm rupture. We have not been able to find a similar case in the English literature. PMID:28484536

Persistence of deep-tendon reflexes during partial cataplexy.

2018-05-01

Deep-tendon reflexes are abolished during generalized cataplexy, but whether this is the case in partial cataplexy currently remains unknown. Partial cataplexy may mimic other neurologic/psychiatric phenomena, and knowledge of the reflexes status may provide information for differential diagnosis. We assessed whether deep-tendon reflexes are persistent during partial cataplexy. Five drug-free patients with typical diagnoses of narcolepsy and clear-cut partial cataplexy were diagnosed in Reference Narcolepsy Centers in France and Italy. Biceps and patellar reflexes were elicited by physicians in charge and video-documented during cataplexy. Reflexes were assessed several times for each patient in different conditions and for various localizations of cataplexy. The absence of tendon reflexes and complete loss of muscle tone during generalized cataplexy was confirmed, but the persistence of those reflexes during several partial cataplectic attacks at different ages, gender, localization of cataplexy (upper limbs, face) and reflexes (biceps, patellar) in drug-naive or withdrawal conditions was documented. The persistence of tendon reflexes during several partial cataplexy episodes contrasts with their absence during generalized cataplexy. This discovery has clinical implications: the persistence of tendon reflexes does not rule out cataplexy diagnosis for partial attacks, whereas their transient abolishment or persistence during generalized attacks indicates cataplexy or pseudocataplexy, respectively.

The protracted and highly variable development of prefrontal cortex regions that support cognitive control has been purported to shape the adult outcome of attention-deficit/hyperactivity disorder (ADHD). This neurodevelopmental model was tested in a prospectively followed sample of 27 adult probands who were diagnosed with ADHD in childhood and 28 carefully matched comparison subjects aged 21-28 years. Probands were classified with persistent ADHD or remitted ADHD. Behavioral and neural responses to the Stimulus and Response Conflict Task (SRCT) performed during functional magnetic resonance imaging (fMRI) were compared in probands and comparison subjects and in probands with persistent and remitted ADHD. Response speed and accuracy for stimulus, response, and combined conflicts did not differ across groups. Orbitofrontal, inferior frontal and parietal activation was lower in probands than comparison subjects, but only for combined conflicts, when demand for cognitive control was highest. Reduced activation for combined conflicts in probands was almost wholly attributable to the persistence of ADHD; orbitofrontal, inferior frontal, anterior cingulate and parietal activation was lower in probands with persistent ADHD than both probands with remitted ADHD and comparison subjects, but did not differ between probands with remitted ADHD and comparison subjects. These data provide the first evidence that prefrontal and parietal activation during cognitive control parallels the adult outcome of ADHD diagnosed in childhood, with persistence of symptoms linked to reduced activation and symptom recovery associated with activation indistinguishable from adults with no history of ADHD.

Data regarding long-term outcome after percutaneous closure of left superior caval vein draining into the left atrium are lacking. The aim of the present study was to report the long-term follow-up by using contrast-enhanced CT. In all, three patients underwent percutaneous closure of left superior caval vein draining into the left atrium between 2005 and 2015. All of them were evaluated clinically and underwent contrast-enhanced CT. In one patient, the Amplatzer® Septal Occluder was used. In two patients, the Amplatzer® Vascular Plug type-1 was preferred: the device size/LSVC diameter ratio was 1.7 in the child and 1.2 in the adult. There were no early-onset or long-term onset complications. CT was performed 1, 2, and 10 years after the procedure, respectively. Complete occlusion of the vessel was documented in all. After 10 years since the procedure, CT revealed a persistent trivial residual shunt through the accessory hemiazygos vein in one patient, in whom the device was implanted above its drainage into the left superior caval vein. When an Amplatzer® Vascular Plug type-1 is oversized compared with the venous vessel diameter, it immediately assumes a dog-bone shape that disappears early to regain its shape memory and nominal size. Percutaneous occlusion of left superior caval vein draining into the left atrium has excellent early and long-term outcomes. The optimal implantation of the device is below the drainage of the accessory hemiazygos vein, when present. The device might be oversized compared with the left superior caval vein diameter according to the age of the patient.

Hydrocolpos in cloacal malformations.

Hydrocolpos is a condition rarely mentioned in the literature. The purpose of this report is to increase the index of suspicion for hydrocolpos in patients with cloaca and to describe our approach for its treatment with the hope that errors in the management of hydrocolpos can be avoided. We reviewed 411 medical records of patients diagnosed with cloaca and managed at our Center during the last 26 years. Emphasis was placed on evaluating for the presence of hydrocolpos, type of drainage, and complications related to the persistence of the hydrocolpos. One hundred seventeen cloaca patients had an associated hydrocolpos (28.4%). Forty-two cases (36%) were initially managed at other institutions at which the hydrocolpos was not drained. Complications experienced by this group included: multiple urinary tract infections (8), hydrocolpos infection (7), sepsis (7), failure to thrive (6), ruptured hydrocolpos (4), and development of hydronephrosis in previously normal kidneys (2). Forty-one patients (35%) had other modalities of treatment, aimed to drain the hydrocolpos, including vesicostomy (26), intermittent perineal catheterization (8), single aspiration (6), or plasty of the perineal orifice (1). In all of these cases, the hydrocolpos persisted or reaccumulated. Thirty-four patients (29%) underwent an effective drainage of the hydrocolpos at birth; 29 at other institutions, 15 with a tube vaginostomy, 13 with a tubeless vaginostomy, and 1 with a catheter placed and left in the vagina through cystoscopy. Five cases had a tube vaginostomy done by us. In all these cases, the vagina remained adequately drained as demonstrated radiologically. Proper drainage of the hydrocolpos alone, with no urologic intervention, dramatically improved the hydronephrosis in 13 cases. Hydrocolpos in patients with cloacas must be diagnosed and treated early in life. Our preferred approach is a transabdominal indwelling vaginostomy tube. The drainage of the hydrocolpos alone may dramatically improve the hydronephrosis, and therefore, we suggest that only after the hydrocolpos is drained should a urological intervention be contemplated. Failure to drain the hydrocolpos can result in serious complications. Copyright 2010 Elsevier Inc. All rights reserved.

Platelets play a major role in thromboembolic events. Increased mean platelet volume (MPV) indicates higher platelet reactivity and also a tendency to thrombosis. Patent foramen ovale (PFO), persistence of the fetal anatomic shunt between right and left atria, is strongly associated with cryptogenic stroke. The aim of this study is to determine the relationship between MPV and PFO and if such an association exists, whether higher MPV levels may require antiplatelet therapy before a thromboembolic event happens, together with a literature review. Thirty patients (15 women, 15 men), free of any cerebrovascular events, were diagnosed with PFO by transesophageal echocardiography (TEE), enrolled as the study group. Thirty consecutive patients (16 women and 14 men), who were diagnosed as normal in TEE, were enrolled as the control group. These two groups were compared according to MPV and anatomical features of the right atrium. There was no significant difference between study and control groups in clinical features and also no difference was observed in platelet counts; however, MPV in the PFO group was significantly higher than the control group (8.38 ±0.93 fl and 7.45 ±0.68 fl respectively). Our results indicate that elevated MPV may be detected in patients with PFO. This might be one of the explanations for the relationship between PFO and cryptogenic stroke; however, larger cohorts are warranted in order to define further mechanisms.

Cardiac hemangiopericytoma is a rare soft tissue tumor. We describe a case of hemangiopericytoma in the left atrium, which was diagnosed as myxoma preoperatively. A 70-year-old woman was admitted with heart failure. An echocardiogram showed a large myxoma-like mass in the left atrium, herniating into the left ventricle; therefore, an emergency operation was performed. Histological examination revealed a malignant hemangiopericytoma. The patient's postoperative course was uneventful, but she died due to a local recurrence 4 months after the operation. © The Author(s) 2014.

Decker, Michael J.; Lin, Jin-Mann S.; Tabassum, Humyra

2009-01-01

Persistent daytime hypersomnolence is associated with significant morbidity and mortality, but its prevalence in the population has been poorly documented. This study sought to characterize the prevalence of persistent daytime hypersomnolence, difficulties initiating and maintaining sleep, unrefreshing sleep, snoring, and the presence of physician-diagnosed sleep disorders in metropolitan, urban, and rural US Georgia populations. Between September 2004 and July 2005, a total of 6,530 randomly selected well and unwell adults, identified by screening interviews of 10,837 households (contacted by random digit dialing), completed a detailed phone interview. Sixteen percent reported persistent problems staying awake during the day; 26% reported persistent problems falling asleep at night; 31% experienced problems sleeping through the night; 34% were bothered by unrefreshing sleep; and 33% reported that they snored. In spite of the high occurrence of reported persistent sleep problems, only 10% of the survey participants reported having been diagnosed with a sleep disorder. These study findings highlight the need for increased public and clinician awareness with respect to proactively indentifying signs and symptoms of sleep disorders, a better understanding of their adverse impact upon morbidity and mortality, and their negative impact upon socioeconomic and academic potential.

Emanuelli, Enzo; Frasson, Giuliana; Cazzador, Diego; Borsetto, Daniele; Denaro, Luca

2018-04-01

Objectives  Ideal treatment of craniopharyngiomas is still controversial. Radiotherapy (RT) is considered effective for recurrences or after subtotal tumor removal (STR). About 40 to 50% of patients may experience tumor cyst expansion soon after RT; in these cases, the role of salvage surgery is debated. Design  Operative video. Setting  Tertiary care center. Participants  An 11-year-old boy diagnosed with persistent craniopharyngioma. In 2015, the patient underwent right frontotemporal craniotomy for STR at another center, complicated by panhypopituitarism. Two years later, fractionated 54-Gy RT was performed on growing residual tumor. After 3 months, he was admitted to our hospital due to persistent malaise, vomiting, pulsating headache, and epistaxis. Ophthalmologic evaluation evidenced left homonymous hemianopsia. Results  A contrast-enhanced magnetic resonance imaging (MRI) showed a 27-mm cystic component enlarging from the cranial end of the persistent craniopharyngioma lesion, extending into the third ventricle. Biventricular hydrocephalus and brain midline shift to the right were present. Compared with the early post-RT MRI, the cystic component of the tumor demonstrated growth. The patient underwent external ventricular drainage placement for emergent treatment of hydrocephalus and endoscopic transsphenoidal surgery. After cystic content drainage, the lesion was completely removed with its capsule. A "gasket seal" technique was performed for skull base reconstruction, with autologous fascia lata, septal bone, and mucoperiosteum from inferior turbinate. Histologic examination confirmed the craniopharyngioma diagnosis. Postoperative MRI showed resolution of the hydrocephalus and complete tumor removal. Conclusion  Although shrinkage of cystic components of craniopharyngioma residuals may occur within 5 to 6 months after RT, salvage surgery is indicated in symptomatic patients.

Backgorund and Aims: Unidirectional endobronchial valves have recently been shown to be beneficial as treatment for persistent air leaks. This report presents a first case of endobronchial valve implantation to treat relapsing pneumothorax in a Chinese patient, and also presents a review of the literature on the use of one-way valve insertion for the treatment of persistent air leaks. The patient did undergo a recent but failed chest tube intervention. By bronchoscopy and using Chartis® system measurements, the upper left lobe (including the left apical bronchus) was closed using a catheter. After the expected decrease in airflow following bronchial occlusion, increased air pressure and decreased spilled air were noted; it was concluded that the pneumothorax was located in the left upper lobe. A Zephyr ® endobronchial valve was placed in the left upper apical bronchus. The health benefits of the procedure were noticed in the following days. Our review suggests that the use of endobronchial valves could be used as an effective, minimally invasive, low-risk intervention for patients with pneumothorax that cannot be treated surgically. © 2015 John Wiley & Sons Ltd.

2015-01-01

Background and purpose In some patients, for unknown reasons pain persists after joint replacement, especially in the knee. We determined the prevalence of persistent pain following primary hip or knee replacement and its association with disorders of glucose metabolism, metabolic syndrome (MetS), and obesity. Patients and methods The incidence of pain in the operated joint was surveyed 1–2 years after primary hip replacement (74 patients (4 bilateral)) or primary knee replacement (119 patients (19 bilateral)) in 193 osteoarthritis patients who had participated in a prospective study on perioperative hyperglycemia. Of the 155 patients who completed the survey, 21 had undergone further joint replacement surgery during the follow-up and were excluded, leaving 134 patients for analysis. Persistent pain was defined as daily pain in the operated joint that had lasted over 3 months. Factors associated with persistent pain were evaluated using binary logistic regression with adjustment for age, sex, and operated joint. Results 49 of the134 patients (37%) had a painful joint and 18 of them (14%) had persistent pain. A greater proportion of knee patients than hip patients had a painful joint (46% vs. 24%; p = 0.01) and persistent pain (20% vs. 4%; p = 0.007). Previously diagnosed diabetes was strongly associated with persistent pain (5/19 vs. 13/115 in those without; adjusted OR = 8, 95% CI: 2–38) whereas MetS and obesity were not. However, severely obese patients (BMI ≥ 35) had a painful joint (but not persistent pain) more often than patients with BMI < 30 (14/21 vs. 18/71; adjusted OR = 5, 95% CI: 2–15). Interpretation Previously diagnosed diabetes is a risk factor for persistent pain in the operated joint 1–2 years after primary hip or knee replacement. PMID:25953426

Milrinone may be an appropriate adjuvant therapy for infants with persistent pulmonary hypertension of the newborn. We aimed to describe the effect of milrinone administration on right and left ventricular function in infants with persistent pulmonary hypertension not responding to inhaled nitric oxide after 4 hours of administration. This is a retrospective review of infants born after or at 34 weeks of gestation with persistent pulmonary hypertension who received milrinone treatment. The primary endpoint was the effect of milrinone on myocardial performance and haemodynamics, including right and left ventricular outputs, tissue Doppler velocities, right ventricle and septal strain, and strain rate. Secondary endpoints examined included duration of inhaled nitric oxide and oxygen support. A total of 17 infants with a mean (standard deviation) gestation and birth weight of 39.8 (2.0) weeks and 3.45 (0.39) kilograms, respectively, were included in the study. The first echocardiogram was performed 15 hours after the commencement of nitric oxide inhalation. Milrinone treatment was started at a median time of 1 hour after the echocardiogram and was associated with an increase in left ventricular output (p=0.04), right ventricular output (p=0.004), right ventricle strain (p=0.01) and strain rate (p=0.002), and left ventricle s` (p<0.001) and a` (p=0.02) waves. There was a reduction in nitric oxide dose and oxygen requirement over the subsequent 72 hours (all p<0.05). The use of milrinone as an adjunct to nitric oxide is worth further exploration, with preliminary evidence suggesting an improvement in both oxygenation and myocardial performance in this group of infants.

Catheter ablation of longstanding (> 1 year) persistent atrial fibrillation (AF) is associated with poor outcome. This might be due to remodelling and fibrosis formation, mainly located in the posterior left atrial (LA) wall. Therefore, we adopted a thoracoscopic epicardial box isolation of the posterior left atrium using bipolar RF energy with intraoperative testing of conduction block. Bilateral thoracoscopic box isolation was performed with a bipolar RF clamp. Entrance block was defined as absence of a conducted electrogram within the box, while exit block was confirmed by pacing at 10.0 V/2 ms. Ablation outcome was evaluated after 3, 6, 12 and 24 months with 12-lead ECGs and 24-hour Holter recordings. Twenty-five consecutive patients were included (58 ± 7 years, persistent AF duration 1.8 ± 0.9 years). Entrance block was achieved in all patients and exit block confirmed if sinus rhythm was achieved. After 17 ± 7 months, 76 % of the patients (n = 19) were free of AF recurrence. One patient died within 1 month and was considered an ablation failure. Four patients with AF recurrences regained sinus rhythm with additional catheter ablation or antiarrhythmic drugs. Treatment of longstanding persistent AF with thoracoscopic epicardial LA posterior box isolation using bipolar RF energy with intraoperative testing of conduction block is feasible and highly effective.

Global aphasia without hemiparesis: language profiles and lesion distribution

PubMed Central

Hanlon, R.; Lux, W.; Dromerick, A.

1999-01-01

OBJECTIVES—Global aphasia without hemiparesis (GAWH) is an uncommon stroke syndrome involving receptive and expressive language impairment, without the hemiparesis typically manifested by patients with global aphasia after large left perisylvian lesions. A few cases of GAWH have been reported with conflicting conclusions regarding pathogenesis, lesion localisation, and recovery. The current study was conducted to attempt to clarify these issues.
METHODS—Ten cases of GAWH were prospectively studied with language profiles and lesion analysis; five patients had multiple lesions, four patients had a single lesion, and one had a subarachnoid haemorrhage. Eight patients met criteria for cardioembolic ischaemic stroke.
RESULTS—Cluster analysis based on acute language profiles disclosed three subtypes of patients with GAWH; these clusters persisted on follow up language assessment. Each cluster evolved into a different aphasia subtype: persistent GAWH, Wernicke's aphasia, or transcortical motor aphasia (TCM). Composite lesion analysis showed that persistent GAWH was related to lesioning of the left superior temporal gyrus. Patients with acute GAWH who evolved into TCM type aphasia had common lesioning of the left inferior frontal gyrus and adjacent subcortical white matter. Patients with acute GAWH who evolved into Wernicke's type aphasia were characterised by lesioning of the left precentral and postcentral gyri. Recovery of language was poor in all but one patient.
CONCLUSIONS—Although patients with acute GAWH are similar on neurological examination, they are heterogeneous with respect to early aphasia profile, language recovery, and lesion profile.

Left atrial appendage (LAA) electric isolation is reported to improve persistent atrial fibrillation (AF) ablation outcomes. However, loss of LAA mechanical function may increase thromboembolic risk. Concomitant LAA electric isolation and occlusion as part of conventional AF ablation has never been tested in humans. We therefore evaluated the feasibility, safety, and efficacy of LAA electric isolation and occlusion in patients undergoing long-standing persistent AF ablation. Patients with long-standing persistent AF (age, 68±7 years; left atrium diameter, 46±3 mm; and AF duration, 25±15 months) underwent AF ablation, LAA electric isolation, and occlusion. Outcomes were compared with a balanced (1:2 ratio) control group who had AF ablation alone. Among 22 patients who underwent ablation, LAA electric isolation was possible in 20. Intraprocedural LAA reconnection occurred in 17 of 20 (85%) patients, predominantly at anterior and superior locations. All were reisolated. LAA occlusion was successful in all 20 patients. There were no major periprocedural complications. Imaging at 45 days and 9 months confirmed satisfactory device position and excluded pericardial effusion. One of twenty (5%) patients had a gap of ≥5 mm requiring anticoagulation. Nineteen of twenty (95%) patients stopped warfarin at 3 months. Without antiarrhythmic drugs, freedom from AF at 12 months after a single procedure was significantly higher in the study group (19/20, 95%) than in the control group (25/40, 63%), P=0.036. Freedom from atrial arrhythmias was demonstrated in 12 of 20 (60%) and 18 of 20 (90%) patients after 1 and ≤2 procedures (mean, 1.3), respectively. Persistent AF ablation, LAA electric isolation, and mechanical occlusion can be performed concomitantly. This technique may improve the success of persistent AF ablation while obviating the need for chronic anticoagulation. URL: https://clinicaltrials.gov.

1992-12-01

Surgical isolation of the left atrium was performed for the treatment of chronic atrial fibrillation secondary to valvular disease in 100 patients who underwent mitral valve operations. From May 1989 to September 1991, 62 patients underwent mitral valve operations (group I); 19, mitral valve operations and DeVega tricuspid annuloplasty (group II); 15, mitral and aortic operations (group III); and 4, mitral and aortic operations and DeVega tricuspid annuloplasty (group IV). Left atrial isolation was performed, prolonging the usual left paraseptal atriotomy toward the left fibrous trigone anteriorly and the posteromedial commissure posteriorly. The incision was conducted a few millimeters apart from the mitral valve annulus, and cryolesions were placed at the edges to ensure complete electrophysiological isolation of the left atrium. Operative mortality accounted for 3 patients (3%). In 79 patients (81.4%) sinus rhythm recovered and persisted until discharge from the hospital. No differences were found between the groups (group I, 80.7%; group II, 68.5%; group III, 86.7%; group IV, 75%; p = not significant). Three late deaths (3.1%) were registered. Long-term results show persistence of sinus rhythm in 71% of group I, 61.2% of group II, 85.8% of group III, and 100% of group IV. The unique risk factor for late recurrence of atrial fibrillation was found to be preoperative atrial fibrillation longer than 6 months. Due to the satisfactory success rate in recovering sinus rhythm, we suggest performing left atrial isolation in patients with chronic atrial fibrillation undergoing valvular operations.

2013-12-01

Platypnea-orthodeoxia syndrome (POS) is a rare clinical phenomenon, associating normal oxygen saturation in a supine position and arterial hypoxemia in an upright position. This pathology can be secondary to an intracardiac shunt, a pulmonary vascular shunt or a ventilation-perfusion mismatch. Cardiac POS occurs in the presence of a right-to-left cardiac shunt, most commonly through a patent foramen ovale (PFO). From our single-center prospective database of percutaneous PFO closure we identified five patients (4 females, mean age: 77 ± 11 years) out of 224 (2.2%) patients with a PFO who presented with a POS of cardiac origin. Transthoracic and transoesophageal echocardiographic examinations revealed the underlying mechanisms of POS and the diagnosis was confirmed by right-and-left cardiac catheterization (RLC) and by measuring serial blood oxygen saturation in the pulmonary veins and left atrium in supine and upright positions. PFO was associated with atrial septal aneurysm and a persistent prominent Eustachian valve in 3 patients. All patients underwent a successful percutaneous PFO closure without any immediate or subsequent complications (mean follow-up of 24 ± 18 months). Immediately after the procedure, mean arterial oxygen saturation improved from 83% ± 3 to 93% ± 2 in an upright position and symptoms disappeared. POS is a rare and under-diagnosed pathology that must be actively investigated in the presence of position-dependent hypoxemia. The diagnostic work-up must exclude other causes of hypoxemia and confirm the intracardiac shunt using either contrast echocardiography or RLC. For cardiac POS, percutaneous PFO closure is a safe and effective technique that immediately relieves orthodeoxia and patient symptoms. © 2013.

Objective This study examined perceptual and motor inhibition in a longitudinal sample of adolescents/young adults who were diagnosed with ADHD in childhood, and as a function of the relative persistence of ADHD. Method Ninety-eight participants diagnosed with ADHD in childhood were re-evaluated approximately 10 years later. Eighty-five never-ADHD controls similar in age, IQ, sociodemographic background, and gender distribution served as a comparison group. Participants were administered a psychiatric interview and the Stimulus and Response Conflict Tasks (Nassauer & Halperin, 2003). Results Participants with childhood ADHD demonstrated slower and less accurate responses to both control and conflict conditions relative to the comparison group, as well as more variable responses in both conditions of the motor inhibition task; there was no specific effect of childhood ADHD on perceptual or motor inhibition. ADHD persisters and partial remitters did not differ in overall accuracy, speed or variability in responding, but relative to partial remitters, persisters demonstrated greater slowing in response to perceptual conflict. Conclusions These findings are consistent with theories positing state regulation, but not inhibitory control deficits in the etiology of ADHD, and suggest that improved perceptual inhibition may be associated with better outcome for ADHD.

Persistent depressive symptoms in children and adolescents are considered a risk factor for the development of major depressive disorder (MDD) later in life. Previous research has shown alterations in white matter microstructure in pediatric MDD but discrepancies exist as to the specific tracts affected. The current study aimed to improve upon previous methodology and address the question whether previous findings of lower fractional anisotropy (FA) replicate in a sample of children with persistent depressive disorder characterized by mild but more chronic symptoms of depression. White matter microstructure was examined in 25 boys with persistent depressive disorder and 25 typically developing children. Tract specific analysis implemented with the Diffusion Tensor Imaging - ToolKit (DTI-TK) was used to probe fractional anisotropy (FA) in eleven major white matter tracts. Clusters within the left uncinate, inferior fronto-occipital and cerebrospinal tracts showed lower FA in the clinical group. FA in the left uncinate showed a negative association with self-reported symptoms of depression. The results demonstrate lower FA in several white matter tracts in children with persistent depressive disorder. These findings support the contention that early onset depression is associated with altered white matter microstructure, which may contribute to the maintenance and recurrence of symptoms.

Patients with sudden onset headache not meeting the criteria of the International Headache Society for new daily persistent headache. How to classify them?

PubMed

Monzillo, Paulo Hélio; Nemoto, Patrícia Homsi

2011-12-01

We conducted a retrospective analysis of the records of 1348 patients regularly treated at the headache clinic of Department of Neurology of Santa Casa de São Paulo, Brazil. Sixty-two patients reported history of daily and persistent headache. From the 62 patients selected, only 21 (group 1) could be diagnosed with new daily-persistent headache (NDPH) according to the International Headache Society (HIS) 2004 criteria. The 41 remaining patients (group 2) could not be diagnosed with NDPH according to IHS-2004 once they presented two or more migraine attack-related symptoms, such as: nausea, photophobia, phonophobia and vomiting, in different combinations. It was not possible to classify them in groups 1 to 4 of primary headaches either. How to classify them? We suggest that the criteria are revised. And one way we can classify them, would be the subdivision: NDPH with migraine features and without migraine features that would allow the inclusion of all individuals present who has a daily and persistent headache from the beginning.

The aim of this study was to investigate medication persistence in Turkish children and adolescents with attention-deficit/hyperactivity disorder (ADHD). The effects of sociodemographic characteristics, symptom severity of ADHD, comorbidity, and treatment-related factors influencing medication persistence in children diagnosed with ADHD were studied. Medication persistence over a continuous 12 month period was evaluated for 877 children and adolescents between 6 and 18 years of age, who were diagnosed with ADHD for the first time and started to receive medication. Medication persistence was determined according to whether or not taking the prescribed medication continued for 12 months after the initiation of treatment. Whereas the symptom severity of ADHD was assessed by using the Turgay Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV)-based Child and Adolescent Behaviour Disorders Screening and Rating Scale-Parents Form (T-DSM-IV-S), perceived medication efficacy after the first treatment was evaluated by the Clinical Global Impressions-Improvement Scale (CGI-I). In this study, medication persistence over a continuous 12 month period occurred at a rate of 30.2% (n=265) in the subjects studied. The hierarchical regression analysis conducted in this research revealed that younger age, higher hyperactivity/impulsivity symptom severity, use of long-acting methylphenidate, addition of another ADHD medication, addition of other psychotropic medications, absence of side effects, and perceived medication efficacy were associated with successful medication persistence over a continuous 12 month period. Understanding the factors that affect medication persistence in ADHD may improve treatment efficacy and symptom control, while minimizing future risks.

Persistent developmental stuttering is characterized by speech production disfluency and affects 1% of adults. The degree of impairment varies widely across individuals and the neural mechanisms underlying the disorder and this variability remain poorly understood. Here we elucidate compensatory mechanisms related to this variability in impairment using whole-brain functional and white matter connectivity analyses in persistent developmental stuttering. We found that people who stutter had stronger functional connectivity between cerebellum and thalamus than people with fluent speech, while stutterers with the least severe symptoms had greater functional connectivity between left cerebellum and left orbitofrontal cortex (OFC). Additionally, people who stutter had decreased functional and white matter connectivity among the perisylvian auditory, motor, and speech planning regions compared to typical speakers, but greater functional connectivity between the right basal ganglia and bilateral temporal auditory regions. Structurally, disfluency ratings were negatively correlated with white matter connections to left perisylvian regions and to the brain stem. Overall, we found increased connectivity among subcortical and reward network structures in people who stutter compared to controls. These connections were negatively correlated with stuttering severity, suggesting the involvement of cerebellum and OFC may underlie successful compensatory mechanisms by more fluent stutterers.

To evaluate the outcomes of women diagnosed with high-risk HPV without cytology evidence of cervical dysplasia. The present retrospective observational study enrolled consecutive women aged at least 18 years diagnosed with high-risk HPV types with negative cytology results at the National Cancer Institute, Milan, Italy, between January 1, 2005, and December 31, 2015. The development of cervical intraepithelial neoplasia (CIN) was assessed. There were 212 patients with high-risk HPV infections with negative cytology included in the analysis. After a mean ± SD follow-up period of 48 ± 33 months, 65 (30.7%) and 26 (12.3%) patients had developed cytologic or histologic cervical dysplasia (low-grade squamous intraepithelial lesion [LSIL]/CIN1+) and high-grade cervical dysplasia (CIN2+), respectively. No patients had invasive cancer. No correlations were observed between type-specific HPV infections and LSIL/CIN1+ and CIN2+. HPV persistence correlated with both LSIL/CIN1+ (P<0.001) and CIN2+ (P<0.001) in univariate analyses; a 6-month increase in HPV persistence was associated with increased risk of developing LSIL/CIN1+ (P=0.010) and CIN2+ (P=0.012) in multivariate analyses. Regardless of cytology findings, patients diagnosed with high-risk HPV types should receive strict colposcopy follow-up, particularly with persistent HPV infections. Further prospective studies are needed to defined optimal surveillance strategies for these patients. © 2017 International Federation of Gynecology and Obstetrics.

A chest radiograph of a 38-year-old woman, who was diagnosed with rheumatic mitral stenosis, revealed cardiac enlargement due to a giant left atrium that was distorting the cardiac structures. The patient's cardiothoracic ratio was approximately 0.90. A giant left atrium can readily be delineated by echocardiography. Optimal timing of surgery is important in cases of mitral stenosis, because delaying mitral valve replacement can lead to fatal outcomes. To our knowledge, the left atrial diameter of 18.7 cm that we found in our patient is the largest reported to date. PMID:17041705

To describe the prevalence and persistence of headache and associated conditions in an inception cohort of U.S. veterans of Iraq and Afghanistan wars. Iraq and Afghanistan war veterans (IAV) suffer from persistent and difficult-to-treat headaches that have been found to co-occur with traumatic brain injury (TBI) and other deployment related comorbidities. This longitudinal retrospective cohort study used data from the national Veterans Health Administration (VA) data repository for IAV who first received VA care in 2008 (baseline) and also received care each year in 2009, 2010, and 2011. We used ICD-9-CM codes, to identify those treated for headache each year (2008-2011). Individuals with headache diagnosed each year were classified as having persistent headache. We also identified comorbidities that may be associated with baseline headache using algorithms validated for use with ICD-9-CM codes. Comorbidities included TBI, posttraumatic stress disorder (PTSD), depression, and conditions associated with these diagnoses (anxiety, memory/attention/cognition, neck pain, tinnitus/hyperacusis, photosensitivity/photo blurring, insomnia, malaise/fatigue, and vertigo/dizziness). Multivariable logistic regression analysis was used to determine characteristics associated with baseline headache as well as those associated with persistent headache. Among all IAV, 38,426 received their first year of VA care in 2008 and had care each year 2009-2011: 13.7% of these were diagnosed with headache in 2008. Veterans diagnosed with headache in 2008 were more likely than those without a headache diagnosis to also have a diagnosis of TBI alone (adjusted odds ratios [AOR] 6.75; 95% CI 5.79-7.86), TBI + depression (AOR 7.09; 95% CI 5.23-9.66), TBI + PTSD (AOR 10.16; 95% CI 8.96-11.53), TBI + PTSD + depression (AOR 9.40; 95% CI 8.12-10.09), and neck pain (AOR 2.44; 95% CI 2.14-2.77). Among those with headache diagnosis in 2008, 24.3% had a headache diagnosis each of the subsequent years of care (persistent headache). While diagnoses of TBI, PTSD, and/or depression at baseline were not associated with headache persistence, persistence was more likely for individuals with baseline tinnitus/hyperacusis (AOR 1.21; 95% CI 1.02-1.45), insomnia (AOR 1.19; 95% CI 1.02-1.39), and vertigo/dizziness (AOR 1.83; 95% CI 1.30-2.57). Our results indicate that TBI alone is a strong predictor of headache in the first year of VA care among IAV and that comorbid psychiatric comorbidities increase the likelihood of headache among individuals with TBI. However, among those with baseline headache, only tinnitus, insomnia, and vertigo were baseline clinical predictors of headache persistence. These results suggest that attention to other symptoms and conditions early in the diagnosis and treatment of headaches may be important for understanding prognosis. These comorbidities offer potential targets for intervention strategies that may help address postdeployment headaches. © 2015 American Headache Society.

To correlate the physical examination finding of distal radial metaphyseal tenderness with plain radiographic and magnetic resonance imaging after acute wrist injury to diagnose occult distal radius fractures. We hypothesized that persistent distal radial metaphyseal tenderness 2 weeks after acute injuries is predictive of an occult fracture. Twenty-nine adult patients presented, after acute trauma, with distal radial metaphyseal tenderness and initial plain radiographs and/or fluoroscopic images that did not show a distal radius fracture. Patients were reevaluated clinically and radiographically at approximately 2 weeks after initial presentation. Patients with persistent distal radial tenderness and negative radiographs underwent magnetic resonance imaging to definitively diagnose an occult distal radius fracture. We calculated the sensitivity and positive predictive value for persistent distal radial metaphyseal tenderness using a 95% confidence interval and standard formulas. Both radiographs and magnetic resonance imaging were used as our endpoint diagnosis for a distal radius fracture. We diagnosed 28 occult distal radius fractures, 8 by follow-up radiograph and 20 by magnetic resonance imaging. The positive predictive value for patients who completed the protocol was 96%. One patient who did not have an occult distal radius fracture had a fracture of the ulnar styloid. Tenderness of the distal radial metaphysis after wrist injury is strongly suggestive of a distal radius fracture despite both normal plain radiographs and fluoroscopic images. Diagnostic III.

This case report describes a 20-yr-old man who presented with retro-orbital pain and blurred vision in his left eye 3 wk after an altitude exposure in a hypobaric chamber. He was found to have significant deficits in color vision and visual fields consistent with an optic neuropathy in his left eye. The patient was diagnosed with decompression sickness and treated with hyperbaric oxygen with a U.S. Navy Treatment Table VI. All signs and symptoms resolved with a single hyperbaric oxygen treatment but recurred. A head MRI revealed a left frontoethmoid sinus opacity. A concomitant sinusitis was diagnosed. The patient had full resolution of symptoms after a total of four hyperbaric oxygen treatments and antibiotic therapy at 6-wk follow-up. Although a para-infectious etiology for this patient's optic neuropathy cannot be excluded, his history of altitude exposure and significant, rapid response to hyperbaric oxygen treatment strongly implies decompression sickness in this case.

Dyssynergic defecation may play an important role in postoperative Hirschsprung's disease patients with severe persistent constipation: analysis of a case series.

2014-10-01

After surgery for Hirschsprung's disease (HD) the majority of patients have satisfactory clinical outcomes. Nevertheless, a substantial number of patients remain who suffer from severe persistent constipation. Current consensus attributes these complaints to the hallmarks of HD. In non-HD patients a cause for severe constipation is dyssynergic defecation. Retrospectively, we reviewed the medical records of ten postoperative HD patients with severe persistent constipation who had undergone extensive anorectal function tests to diagnose the reason for the constipation. We analyzed the results of these tests. During the last three years, ten postoperative HD patients with severe persistent constipation were given extensive anorectal function tests. All ten patients were diagnosed with dyssynergic defecation. The ages at the time of diagnosis ranged from 7 to 19years with a median age of 12years. Signs of an enlarged rectum were seen in all ten patients, with a maximum measured value of 845mL. Patients with HD may also suffer from dyssynergic defecation. It is important to consider this possibility when dealing with severe persistent constipation in postoperative HD patients. Viable options for treating dyssynergic defecation are available that could prevent irreversible long-term complications. Copyright © 2014 Elsevier Inc. All rights reserved.

Surgical isolation of the left atrium was performed for the treatment of chronic atrial fibrillation secondary to valvular disease in 100 patients who underwent valve surgery. From May 1989 to September 1991, 62 patients underwent mitral valve surgery (Group I), 19 underwent mitral valve surgery and DeVega tricuspid annuloplasty (Group II), 15 underwent mitral and aortic surgery (Group III), and 4 patients underwent mitral and aortic surgery and DeVega tricuspid annuloplasty (Group IV). Left atrial isolation was performed prolonging the usual left paraseptal atriotomy towards the left fibrous trigone anteriorly, and the postero-medial commissure posteriorly. The incision was conducted a few millimeters apart from the mitral valve annulus, and cryolesion were placed at the edges to ensure complete electrophysiological isolation of the left atrium. Operative mortality accounted for 3 cases (3%). In 79 patients (81.4%) sinus rhythm recovered and persisted until discharge from the hospital. No differences were found between the groups (Group I: 80.7%; Group II: 68.5%; Group III 86.7%, Group IV 75% - p = N.S.). Three cases of late mortality (3.1%) were registered. long-term results showed persistence of SR in 71% of Group I, 61.2% of Group II, 85.8% of Group III, and 100% of Group IV. The unique risk factor for late recurrency of atrial fibrillation was found to be a duration of preoperative AF longer than 6 months. Due to the high success rate in recovering the sinus rhythm, we suggest left atrial isolation in patients with chronic atrial fibrillation undergoing valvular surgery.

Déjà vu is a common experience among the normal population. However, in individuals with temporal lobe epilepsy, it often occurs as a seizure manifestation. The specific cause of such déjà vu is not yet known. Here, we report a case of epilepsy with persistent déjà vu. The patient described the state as if he were living the same life he had lived before. Blood perfusion single-photon-emission computed tomography (SPECT) performed during the persistent déjà vu showed hyperperfusion in the left medial temporal area; discontinuation of déjà vu was accompanied by disappearance of the hyperperfused area on SPECT. Analysis with three-dimensional co-registration of SPECT and MRI revealed that the hyperperfused area during the persistent déjà vu was in the entorhinal cortex of the left temporal lobe. According to recent theories of recognition memory, malfunction of the parahippocampal area may cause déjà vu. It is also suggested that epileptic activity in the parahippocampal area, especially the entorhinal cortex, may elicit déjà vu. Copyright © 2011 Elsevier Inc. All rights reserved.

Students Left Behind: Measuring 10th to 12th Grade Student Persistence Rates in Texas High Schools

The No Child Left Behind Act requires states to publish high school graduation rates for public schools and the U.S. Department of Education is currently considering a mandate to standardize high school graduation rate reporting. However, no consensus exists among researchers or policy-makers about how to measure high school graduation rates. In this paper, we use longitudinal data tracking a cohort of students at 82 Texas public high schools to assess the accuracy and precision of three widely-used high school graduation rate measures: Texas’s official graduation rates, and two competing estimates based on publicly available enrollment data from the Common Core of Data. Our analyses show that these widely-used approaches yield inaccurate and highly imprecise estimates of high school graduation and persistence rates. We propose several guidelines for using existing graduation and persistence rate data and argue that a national effort to track students as they progress through high school is essential to reconcile conflicting estimates.

We report the case of a 40-year-old alcoholic male patient, hospitalized with an acute ataxia of stance and gait, ocular muscle weakness with nystagmus and a global apathetic-confusional state. After admission, an amnestic syndrome with confabulation was also observed and diagnosis of Wernicke-Korsakoff syndrome was made. Under treatment with intravenous thiamine, the patient recovered completely from gaze weakness and ataxia, whereas a severe amnestic syndrome persisted. Fluorodeoxyglucose (FDG) positron emission tomography (PET) showed bilateral thalamic and severe bilateral temporal-parietal hypometabolism resembling a pattern typical for Alzheimer's disease. Longitudinal assessment of the alcohol-abstinent and thiamine-substituted patient revealed improvements of clinical state and neuropsychological performance that were paralleled by recovered cerebral glucose metabolism. In contrast to metabolic rates that increased between 7.1% (anterior cingulate, left) and 23.5% (parietal, left) in cortical areas during a 9-month remission period, thalamic glucose metabolism remained severely disturbed over time (change: left +0.2%, right +0.3%).

Between 2006 and 2014, 55 patients underwent implantation of HeartMate II LVAD. Five were diagnosed with malignant tumours: 2 renal, 2 lung and 1 breast tumours. The renal tumours were diagnosed during the preimplantation screening. An LVAD was implanted in both followed by partial nephrectomies 8 and 9 months later. The lung cancers were diagnosed after device implantation, a left pulmonary segmentectomy and a right upper sleeve lobectomy were performed. The breast cancer was diagnosed few months after support and a tumourectomy with lymphadenectomy was performed. Tumour resection was performed successfully in all patients. Prior to surgery haemostasis, device and heart function were evaluated. During surgery, haemodynamics and anticoagulation were monitored. Reoperations were necessary to evacuate haemothorax after lobectomy and an abdominal haematoma post-nephrectomy. After discussion with oncologists, 3 patients were relisted for heart transplantation. Two were successfully transplanted 2 and 3 years after partial nephrectomy with an actual survival of 56 and 59 months after the cancer diagnosis. The follow-up revealed no cancer recurrences. Malignant tumours during support with LVAD can be successfully resected. A multidisciplinary evaluation in these high-risk patients is mandatory. After careful evaluation, regaining the patient's heart transplant candidacy is possible. © The Author 2015.

3 alpaca crias and cadavers of an alpaca cria and a llama cria were evaluated for evidence of esophageal dysfunction. All 5 crias were between 3 and 5 months of age when clinical signs developed, and all had a thin body condition when examined. Clinical signs included coughing, regurgitation, and grossly visible esophageal peristaltic waves. A barium esophagram was used to diagnose esophageal obstruction, megaesophagus, and a vascular ring anomaly (VRA). Fluoroscopy was used to evaluate deglutition, esophageal peristalsis, and the extent of esophageal dilation in 1 alpaca cria. A persistent right aortic arch was identified in 1 alpaca cria, and a left aortic arch with right ductus arteriosus or ligamentum arteriosum and an aberrant right subclavian artery were identified in the 4 remaining crias. Surgical correction of the VRA was attempted in the 3 live alpaca crias. It was complicated by the conformation and location of each VRA and inaccurate anatomic diagnosis of the VRAs before surgery. Treatment was universally unsuccessful because of intraoperative complications and the persistence of clinical signs after surgery. Megaesophagus is typically an idiopathic condition in camelids. However, these findings suggested that camelids with esophageal dysfunction during the neonatal period may have a VRA. The prognosis is grave for camelids with VRA, and accurate anatomic diagnosis of the VRA via the use of advanced imaging techniques (eg, angiography, computed tomography, or magnetic resonance imaging) may improve the success of surgical intervention.

A 61-year-old man with cough and white sputum had an abnormal pulmonary mass in the left lower lobe in the computed tomography (CT) imaging. According to the lung cancer multidisciplinary team (MDT) discussion, the patient took the left lower lobe resection and lymphadenectomy and finally diagnosed as left lung adenocarcinoma with TNM stage IIIA (pT3N2M0). After four cycles of postoperative chemotherapy with pemetrexed and nedaplatin and 10-month release, a solitary pulmonary nodule (SPN) appeared in the middle lobe of right lung in CT scanning. The patient took a second operation “the right middle lobe resection” and was diagnosed as left lung adenocarcinoma at TNM stage IV (pT3N2M1a, two lungs) with neither EGFR mutation nor ALK-EML4 fusion gene. After operation, the patient took another four cycles of postoperative chemotherapy with Docetaxel and Nedaplatin. During the follow-up, another PET/CT scanning reported that several enlarged mediastinal lymph nodes, a SPN in left upper lobe and lesion in cerebellum and the brain metastasis was also proved in MRI. The patient was now diagnosed as left lung adenocarcinoma at TNM stage IV (pT3N2M1b, brain). In the third-line therapy, the patient took the stereotactic radiotherapy for metastatic mediastinal lymph nodes and took erlotinib once a day after the radiotherapy. However, the number of small lesions on lungs was increased and the brain metastasis was enlarged. The stereotactic radiotherapy for the single brain metastasis and single agent chemotherapy of abraxane were taken. The whole body examination suggested that there was progression-free after two cycles of chemo. The patient is now took five cycles of single agent chemotherapy of abraxane. The latest whole body examination showed disease was stable with no new lesions and metastasis, performance status (PS) score is 0 and the overall survival (OS) time is 34 months. PMID:25806349

Lyme borreliosis is the most common vector-borne disease in Europe and North America. The objective of this study is to estimate the incidence of tick bites and Lyme borreliosis, representative of our entire country, including erythema migrans, disseminated Lyme borreliosis and persisting symptoms attributed to Lyme borreliosis. A questionnaire on clinical diagnoses of Lyme borreliosis was sent to all GPs, company physicians, and medical specialists. To adjust for possible misclassification and telescoping bias, we sent additional questionnaires to categorize reported cases according to likelihood of the diagnosis and to exclude cases diagnosed outside the target period. Adjusted annual incidence rate for disseminated Lyme borreliosis was 7.7 GP reports per 100,000 inhabitants, and for persisting symptoms attributed to Lyme borreliosis was 5.5 GP reports per 100,000 inhabitants, i.e. approximately 1,300 and 900 cases respectively. GP consultations for tick bites and erythema migrans diagnoses were 495 and 132 per 100,000 inhabitants, respectively, i.e. 82,000 and 22,000 cases in 2010. This is the first reported nationwide physician survey on the incidence of tick bites and the whole range of manifestations of Lyme borreliosis, including persisting symptoms attributed to Lyme borreliosis. This is crucial for complete assessment of the public health impact of Lyme borreliosis.

Affect and neural activity in women with PTSD during a task of emotional interference.

The current study sought to determine the relationship between self-reported dimensions of affect and activation in brain regions associated with emotion regulation in PTSD during a task of non-conscious emotional processing in interpersonal trauma survivors with PTSD and healthy controls. Participants included 52 women diagnosed with PTSD and 18 female healthy controls. All participants completed a clinical assessment including the SCID, CAPS, and PANAS followed by a functional MRI assessment including a task of implicit emotional conflict. When PTSD participants were oriented to fearful faces, negative affect (NA) was inversely related to activation in the left amygdala and positive affect (PA) was inversely related to activation in the right amygdala. When ignoring fearful faces, NA was positively associated with activation in the right parahippocampal gyrus and PA was inversely related to activation in the left hippocampus. Similar results were observed in healthy controls regarding PA. However, NA was not significantly related to any region of interest in healthy controls. Limitations include the homogeneity of the healthy controls with regard to racial diversity, results may only be specific to female interpersonal trauma survivors with PTSD, and neutral faces within the conflict task may be perceived as negative by clinical samples. Persistent, increased NA may represent a proxy for disruptions in emotional processing in interpersonal trauma survivors with PTSD. As such, clinicians may prioritize increasing emotional awareness through emotion regulation and/or distress tolerance strategies in this population. Copyright © 2016 Elsevier B.V.

Infective endocarditis (IE) is an infection of the inner lining of the heart with high morbidity and mortality despite medical and surgical advancements in recent decades. Hypertrophic cardiomyopathy (HC) is one of several medical conditions that have been linked to an increased risk of IE, but there is a paucity of data on this association. We therefore sought to define the clinical phenotype of IE in patients with HC at a single tertiary care center. A retrospective cohort of 30 adult patients with HC diagnosed with IE between January 1, 2006 and December 31, 2016 at Mayo Clinic Rochester were identified. Similar rates of aortic (n = 14) and mitral (n = 16) valve involvement by IE were noted (47% vs 53%). This finding persisted even in patients with left-ventricular outflow tract obstruction and systolic anterior motion of the mitral valve. Symptomatic embolic complications occurred in 10 cases (33%). Surgical intervention was performed in 11 cases (37%). One-year mortality was remarkably low at 7%. In conclusion, in the largest single-center cohort of IE complicating HC, there were similar rates of both mitral and aortic valve involvement regardless of the presence of left ventricular outflow tract obstruction, which is contrary to a long-standing tenet regarding the association of HC and IE. Moreover, no "high risk" IE subset was identified based on HC-related parameters. Copyright © 2017 Elsevier Inc. All rights reserved.

2016-10-15

Left ventricular (LV) thrombus formation following myocardial infarction (MI) has not been well characterized since the advent of primary percutaneous coronary intervention (pPCI). Ascertainment of the utility of prophylactic anticoagulation is hindered by the lack of reliable information on its modern incidence. We sought to provide an estimate of the rate of LV thrombus formation in patients treated with pPCI for ST segment elevation MI (STEMI) by means of a systematic review and meta-analysis. We searched Ovid MEDLINE and Ovid EMBASE databases for studies between 1990 and 2015 documenting LV thrombi after STEMI treated with pPCI. We estimated the rate of echocardiographically-diagnosed LV thrombi within 90days of pPCI, calculating the rate of LV thrombi after STEMI in any infarct territory as well as only anterior infarcts. From an initial yield of 1144 studies, inclusion criteria were met by 19 studies, including 10,076 patients across 27 centers in 9 countries. Rate of LV thrombi after all STEMI was 2.7% (95% CI 1.9%-3.5%) and 9.1% (95% CI 6.6%-11.6%) after anterior STEMI. Among anterior STEMI, there was an inverse relationship between size of study and rate of LV thrombi. LV thrombi persist as an important part of the management of STEMI after pPCI, particularly among anterior infarcts. Estimating risk of thrombus formation and embolization as well as utility of treatment remains critical. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

We describe a case of primary acinar cell carcinoma (ACC) originating in the liver in a 54-year-old female, diagnosed following persistent abnormal elevated liver function. Imaging revealed two masses, one dominant lesion in the right hepatic lobe and another in segment IVA. A right hepatectomy was performed to remove the larger lesion, while the mass in segment IVA was unresectable due to its proximity to the left hepatic vein. Immunohistochemical staining showed positivity for trypsin and chymotrypsin. Postoperatively the patient underwent hepatic arterial embolization of the other unresectable lesion followed by FOLFOX chemotherapy. At 20 months from diagnosis the patient is currently under observation with a decreasing necrotic mass and no other disease evident. Based on histology, immunohistochemistry and radiological findings a diagnosis of primary ACC of the liver was made. Genomic assessment of somatic mutations within the patient’s tumor was also performed through next generation sequencing and findings were consistent with an acinar malignancy. This case highlights a rare tumor subtype treated with a combination of therapeutic modalities through a multidisciplinary approach. PMID:29184698

Breast cancer metastasis to the stomach is relatively rare. Unlike infiltrating ductal carcinoma, invasive lobular carcinoma (ILC) has a high tendency to metastasize to the stomach. The present study reports a case of a 53-year-old female who had undergone a modified radical mastectomy of the left breast for ILC eight years previously and presented at the clinic seeking treatment for epigastric discomfort from sour regurgitation and belching that had persisted for one month. Gastroscopy revealed multiple apophysis lesions in the stomach, which were diagnosed as metastatic tumors to the stomach. The diagnosis was further established using histological and immunohistochemical analyses for gross cystic disease fluid protein-15, cytokeratin (CK) 7 and CK20. The patient was treated with systemic chemotherapy without surgery. During the treatment, two gastroscopy procedures revealed that the apophysis lesions in the gastric body had narrowed significantly. Few cases of breast cancer metastasizing to the stomach have been reported, particularly those that have been confirmed using gastroscopy. The present study reports a case of breast cancer metastasis to the stomach to raise awareness of the condition.

Xp11.2 translocation/transcription factor enhancer 3 (TFE3) fusion gene associated with renal cell carcinoma (Xp11.2 translocation RCC) is rare and occurs predominantly in children and adolescents. The current study reports the case of a 14-year-old male with Xp11.2 translocation RCC, who presented with chest pain that had persisted for 1 month. A solid neoplasm was located in the left kidney of the patient. Contrast-enhanced computed tomography revealed the presence of a solid mass in the kidney, with uneven enhancement. Destruction of multiple bones was also observed. The patient was treated with a radical nephrectomy. The pathological examination of the tumor revealed that the tumor cells contained an eosinophilic cytoplasm in the renal interstitial tissue. Immunohistochemistry revealed that the tumor cells expressed P504S, cluster of differentiation 10, pan-cytokeratin, vimentin and TFE3. In conclusion, Xp11.2 translocation RCC is a rare type of kidney cancer. Diagnosing this disease prior to surgery is challenging, and providing a definite diagnosis requires histopathological and immunohistochemical examination, while genetic analysis may also be required.

Acral persistent papular mucinosis is a rare localized form of lichen myxedematosus with few case reports and no documented therapeutic options. To report full resolution of acral persistent papular mucinosis after electrocoagulation. Case report of a 51-year-old white female diagnosed with an acral persistent papular mucinosis. The clinical and histopathologic features, treatment provided, and response to treatment are detailed. Acral persistent papular mucinosis presented as multiple asymptomatic normochromic papules on the wrists. Treatment with topical and intralesional steroids was unsatisfactory. Gentle electrocoagulation led to complete resolution of the lesions and negligible scarring. The favorable results remained for 6 months of follow-up, and no new lesions have emerged. Our case of acral persistent papular mucinosis was successfully treated with electrocoagulation and long-lasting, excellent cosmetic results.

Longitudinal studies of children diagnosed with ADHD report widely ranging ADHD persistence rates in adulthood (5-75%). This study documents how information source (parent vs. self-report), method (rating scale vs. interview), and symptom threshold (DSM vs. norm-based) influence reported ADHD persistence rates in adulthood. Five hundred seventy-nine children were diagnosed with DSM-IV ADHD-Combined Type at baseline (ages 7.0-9.9 years) 289 classmates served as a local normative comparison group (LNCG), 476 and 241 of whom respectively were evaluated in adulthood (Mean Age = 24.7). Parent and self-reports of symptoms and impairment on rating scales and structured interviews were used to investigate ADHD persistence in adulthood. Persistence rates were higher when using parent rather than self-reports, structured interviews rather than rating scales (for self-report but not parent report), and a norm-based (NB) threshold of 4 symptoms rather than DSM criteria. Receiver-Operating Characteristics (ROC) analyses revealed that sensitivity and specificity were optimized by combining parent and self-reports on a rating scale and applying a NB threshold. The interview format optimizes young adult self-reporting when parent reports are not available. However, the combination of parent and self-reports from rating scales, using an 'or' rule and a NB threshold optimized the balance between sensitivity and specificity. With this definition, 60% of the ADHD group demonstrated symptom persistence and 41% met both symptom and impairment criteria in adulthood. © 2016 Association for Child and Adolescent Mental Health.

We report 2 rare cases of extraskeletal Ewing's sarcoma, one is arising primarily from the posterior mediastinum in a middle-aged man (patient 1), and the other one is arising from the left kidney in a young male patient (patient 2). The CT in the first case showed a large mass of heterogeneous texture, with areas of cystic changes in the right side of the posterior mediastinum, no underlying bony changes or intra-spinal extension, and this mass was diagnosed as lymphoma. The second case showed almost complete replacement of the left kidney by a mass with extension through the renal vein and inferior vena cava, and it was diagnosed as renal cell carcinoma. The histological analysis of these lesions revealed extraskeletal Ewing's sarcoma.

A 40-year-old woman experiencing sudden dyspnea went to her personal doctor for advice. She was previously diagnosed with endometriosis and prescribed oral contraceptives for treatment. During earthquakes, she spent 7 nights sleeping in a vehicle. The patient had swelling and pain in her left leg and high D-dimer concentration levels. A contrast-enhanced computed tomography scan revealed a contrast deficit in the bilateral pulmonary artery and in the left lower extremity. She was diagnosed with pulmonary thromboembolism (PTE), and anticoagulation therapy was initiated. This present case is the first report of PTE attributed to the use of oral contraceptives after earthquakes.

2014-03-01

To establish whether chest radiographic findings suggestive of lower airway obstruction (LAO) disease support the diagnosis of asthma in pediatric patients with persistent cough in an outpatient setting. 180 patient charts were reviewed. The patients were children aged 1 to 18 years referred over a 3-year period to a pediatric pulmonary subspecialty clinic for evaluation of cough lasting ≥ 4 weeks. Chest radiographic images obtained after the initial evaluation of 90 patients diagnosed with cough-variant asthma and 90 patients diagnosed with persistent cough from nonasthma origins were compared with radiologic findings of a control group consisting of patients with a positive tuberculin skin test and no respiratory symptoms. Increased peribronchial markings/peribronchial cuffing and hyperinflation were considered radiographically suggestive findings of LAO disease. Children diagnosed with cough-variant asthma at the initial evaluation had higher rates of chest radiographic findings suggestive of LAO disease (30.00%) than children with persistent cough from other causes (17.80%) or those with a positive tuberculin skin test and no respiratory symptoms (8.16%) (overall P value = 0.0063). They also had higher rates of spirometry abnormalities suggestive of an LAO defect. Children with chest radiographic findings suggestive of LAO disease were found to be younger than those with normal chest radiographic findings (5.0 ± 2.7 years vs 8.6 ± 4.7 years; P < 0.0001). This study suggests that chest radiographic findings indicative of an LAO in correlation with the clinical presentation can support the diagnostic suspicion of asthma, especially in younger children unable to perform spirometry.

Paraduodenal hernias are congenital internal hernias that usually present with non-specific symptoms, and are therefore rarely diagnosed preoperatively. Left-sided paraduodenal hernias are three times more likely to occur than right-sided ones. Both hernias present similarly, but have a differing embryological basis. Here, the case of a 76-year-old woman with a left paraduodenal hernia presenting with small bowel obstruction is presented, and a brief discussion of the literature on its diagnosis and management given.

2014-02-01

Pelvic radiation disease (PRD) also widely known as "radiation proctopathy" is a well recognised late side-effect following conventional prostate radiotherapy. However, endoscopic evaluation and/or specialist referral for new or persistent post-prostate radiotherapy bowel symptoms is not routine and serious diagnoses may potentially be missed. Here we report a policy of endoscopic evaluation of bowel symptoms persisting >90 days post radiotherapy for prostate cancer. A consecutive series of 102 patients who had radical prostate intensity-modulated radiotherapy (IMRT)/image-guided radiotherapy (IGRT) and who had new or ongoing bowel symptoms or positive faecal occult blood tests (FOBT) on follow up visits more than three months after treatment, were referred for endoscopic examination. All but one (99%) had full colonoscopic investigation. Endoscopic findings included gastric/colonic/rectal polyps (56%), diverticular disease (49%), haemorrhoids (38%), radiation proctopathy (29%), gastritis/oesophagitis (8%) and rarer diagnoses, including bowel cancer which was found in 3%. Only four patients (4%) had radiation proctopathy without associated pathology and 65 patients (63%) had more than one diagnosis. If flexible sigmoidoscopy alone were used, 36.6% of patients and 46.6% patients with polyp(s) would have had their diagnoses missed. Our study has shown that bowel symptoms following prostate IMRT/IGRT are due to numerous diagnoses other than PRD, including malignancy. Routine referral pathways should be developed for endoscopic evaluation/specialist review for patients with new or persistent bowel symptoms (or positive FOBT) following prostate radiotherapy. This recommendation should be considered for incorporation into national guidelines. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

2015-01-01

Introduction Pain present 6 months following root canal treatment (RCT) may be either of odontogenic or nonodontogenic origin. This is importance because treatments and prognoses are different; therefore the aim of this study was to provide specific diagnoses of patients reporting pain 6 months after receiving initial orthograde RCT. Methods We enrolled patients from the Midwest region of an existing prospective observational study of pain after RCT. Pain at 6 months was defined as ≥1 day of pain and average pain intensity of at least 1/10 over the preceding month. An Endodontist and an Orofacial Pain practitioner independently performed clinical evaluations, which included periapical and cone-beam CT radiographs, to determine diagnoses. Results Thirty-eight out of the 354 eligible patients in the geographic area (11%) met the pain criteria, with 19 (50%) consenting to be clinically evaluated. As the sole reason for pain, 7 patients (37%) were given odontogenic diagnoses (4 involving the RCT tooth, 3 involving an adjacent tooth). Eight patients (42%) were given nonodontogenic pain diagnoses (7 from referred temporomandibular disorder (TMD) pain, 1 from persistent dentoalveolar pain disorder (PDAP)). Two patients (11%) had both odontogenic and nonodontogenic diagnoses, while 2 (11%) no longer fit the pain criteria at the time of the clinical evaluation. Conclusion Patients reporting “tooth” pain 6 months following RCT had a nonodontogenic pain diagnosis accounting for some of this pain, with TMD being the most frequent nonodonotgenic diagnosis. Dentists should have the necessary knowledge to differentiate between these diagnoses to adequately manage their patients. PMID:25732400

[A Case of Cystic Cervical Lymph Node Metastasis of HPV-positive Tonsil Cancer, Being Discriminated as the Branchiogenic Carcinoma].

PubMed

Kambara, Rumi; Tamai, Masamitsu; Horii, Arata

2016-02-01

In recent years, human papillomavirus (HPV)-positive oropharyngeal carcinomas have been increasing. The first manifestation of these tumors is frequently as cystic metastasis to cervical lymph nodes that may precede recognition of the primary tumor, so, they often result in misdiagnosis as branchial cleft cysts. We report a case of cystic cervical lymph node metastasis of HPV-positive tonsil cancer. The patient was a 70-years-old man who noticed a mass on his left neck. The tumor was large and soft, and it was diagnosed as benign in fine-needle aspiration cytology. We diagnosed the tumor as a branchial cleft cyst and undertook surgery. The histopathological diagnosis was squamous cell carcinoma arising from a branchiogenic cyst. However, because it did not satisfy the diagnostic criteria, we diagnosed the tumor as an unknown primary tumor. One year later, left tonsil cancer was suspected based on PET-CT imaging and a left tonsillectomy was undertaken, whereafter tonsil cancer was found. In p16 immunostaining, it was positive in both cystic mass and tonsil. The cervical mass was cystic lymph node metastasis of HPV-positive tonsil cancer. It is important to investigate the oropharynx, when we found cystic cervical mass, because HPV-positive oropharyngeal carcinoma frequently results in cystic neck metastasis.

A giant ovarian cyst in a neonate.

Soccorso, Giampiero; Walker, Jenny

2009-06-01

Antenatally diagnosed abdominal cysts are common, and frequently are ovarian in origin, which usually regress spontaneously. Surgery is indicated in the infantile period in case of very large, persisting or symptomatic cysts. Many surgeons feel that watchful waiting can be justified in newborns with simple and complex cysts. We present a neonate with an ovarian cyst diagnosed antenatally by ultrasound (US) and showing persistent enlargement within 3 months after birth when reached a diameter of 13 cm. Assessment and treatment is described. The extremely large, non-resolving ovarian cysts in neonates present a major challenge for clinicians and should be treated by surgery to avoid complications. We advocate laparotomy and cystectomy when possible to avoid unnecessary loss of functional ovarian tissue.

New daily persistent headache in children and adolescents.

PubMed

Baron, Eric P; Rothner, A David

2010-03-01

New daily persistent headache (NDPH) is a form of chronic daily headache (CDH) that may have features of both migraine and tension-type headache. In contrast with other types of CDH, NDPH is characterized by patients recalling the specific date their unremitting daily headache began. In comparison, chronic tension-type headache and chronic migraine are preceded by a gradually increasing frequency of headache. After several months, all three of these CDH forms often have a similar phenotype, making early history a key to diagnosing NDPH. Evaluations to exclude secondary causes are necessary but usually negative. NDPH is difficult to treat and requires a multimodal approach. Questions regarding NDPH remain unanswered. Additional prospective studies are necessary to further understand, characterize, diagnose, and treat NDPH.

Penile revascularization is a surgical treatment option for erectile dysfunction (ED) in healthy individuals due to a focal arterial occlusion in the absence of generalized vascular disease. Most described failures have been attributed to graft stenosis or disruption of the anastomosis. We report a novel phenomenon called Penile Artery Shunt Syndrome that contributed to persistent ED in a patient after penile microvascular arterial bypass surgery. A 26-year-old man presented for evaluation of long-standing ED, which was attributed to trauma sustained 12 years earlier. He had difficulty obtaining and maintaining erections despite oral pharmacotherapy. Clinical data related to the case were studied, analyzed, and reviewed with urologic and radiologic specialists at multiple centers that collaborated in the care of this patient. Penile duplex ultrasound peak systolic velocities and five-item International Index for Erectile Function questionnaire scores were the main outcome measures. Initial diagnostic workup of the patient confirmed severe insufficiency of the left cavernosal artery, with no evidence of venous leak. The patient underwent penile microvascular arterial bypass surgery with anastomosis of the left inferior epigastric artery to the left dorsal penile artery. The patient had persistence of severe ED despite patent anastomosis by penile duplex ultrasound. Subsequent arteriography revealed an arterial shunt due to an aberrant obturator artery arising from the donor inferior epigastric artery. The patient underwent embolization of the aberrant obturator artery, with resolution of the shunt and marked improvement in erectile function. The presence of an aberrant obturator artery arising from the inferior epigastric artery may predispose to persistent ED after revascularization due to the creation of a shunt phenomenon. Pelvic arteriography may be useful in identifying anomalous anatomic considerations prior to penile revascularization and to evaluate patients with persistent postoperative ED. © 2014 International Society for Sexual Medicine.

Atrial fibrillation (AF) is a progressive condition that begins with hemodynamic and/or structural changes in the left atrium (LA) and evolves through paroxysmal and persistent stages. Because of limitations with current noninvasive imaging techniques, the relationship between LA structure and function is not well understood. Sixty-five patients (age, 61.2+/-14.2 years; 67% men) with paroxysmal (44%) or persistent (56%) AF underwent 3D delayed-enhancement MRI. Segmentation of the LA wall was performed and degree of enhancement (fibrosis) was determined using a semiautomated quantification algorithm. Two-dimensional echocardiography and longitudinal LA strain and strain rate during ventricular systole with velocity vector imaging were obtained. Mean fibrosis was 17.8+/-14.5%. Log-transformed fibrosis values correlated inversely with LA midlateral strain (r=-0.5, P=0.003) and strain rate (r=-0.4, P<0.005). Patients with persistent AF as compared with paroxysmal AF had more fibrosis (22+/-17% versus 14+/-9%, P=0.04) and lower midseptal (27+/-14% versus 38+/-16%, P=0.01) and midlateral (35+/-16% versus 45+/-14% P=0.03) strains. Multivariable stepwise regression showed that midlateral strain (r=-0.5, P=0.006) and strain rate (r=-0.4, P=0.01) inversely predicted the extent of fibrosis independent of other echocardiographic parameters and the rhythm during imaging. LA wall fibrosis by delayed-enhancement MRI is inversely related to LA strain and strain rate, and these are related to the AF burden. Echocardiographic assessment of LA structural and functional remodeling is quick and feasible and may be helpful in predicting outcomes in AF.

Spectral analysis identifies localized sites of high-frequency activity during atrial fibrillation (AF). This study sought to determine the effectiveness of using real-time dominant frequency (DF) mapping for radiofrequency ablation of maximal DF (DFmax) sites and elimination of left-to-right frequency gradients in the long-term maintenance of sinus rhythm (SR) in AF patients. DF mapping was performed in 50 patients during ongoing AF (32 paroxysmal, 18 persistent), acquiring a mean of 117 +/- 38 points. Ablation was performed targeting DFmax sites, followed by circumferential pulmonary vein isolation. Ablation significantly reduced DFs (Hz) in the LA (7.9 +/- 1.4 vs. 5.7 +/- 1.3, P <.001), coronary sinus (CS) (5.7 +/- 1.1 vs. 5.3 +/- 1.2, P = .006), and RA (6.3 +/- 1.4 vs. 5.4 +/- 1.3, P <.001) abolishing baseline left-to-right atrial DF gradient (1.7 +/- 1.7 vs. 0.2 +/- 0.9; P <.001). Only a significant reduction in DFs in all chambers with a loss of the left-to-right atrial gradient after ablation was associated with a higher probability of long-term SR maintenance in both paroxysmal and persistent AF patients. After a mean follow-up of 9.3 +/- 5.4 months, 88% of paroxysmal and 56% of persistent AF patients were free of AF (P = .02). Ablation of DFmax sites was associated with a higher probability of remaining both free of arrhythmias (78% vs. 20%; P = .001) and free of AF (88% vs. 30%; P <.001). Radiofrequency ablation leading to elimination of LA-to-RA frequency gradients predicts long-term SR maintenance in AF patients.

Motor balance in developmental stuttering (DS) was investigated with Transcranial Magnetic Stimulation (TMS), with the aim to define novel neural markers of persistent DS in adulthood. Eleven DS adult males were evaluated with TMS on tongue primary motor cortex, compared to 15 matched fluent speakers, in a "state" condition (i.e. stutterers vs. fluent speakers, no overt stuttering). Motor and silent period thresholds (SPT), recruitment curves, and silent period durations were acquired by recording tongue motor evoked potentials. Tongue silent period duration was increased in DS, especially in the left hemisphere (P<0.05; Hedge's g or Cohen's dunbiased = 1.054, i.e. large effect size), suggesting a "state" condition of higher intracortical inhibition in left motor cortex networks. Differences in motor thresholds (different excitatory/inhibitory ratios in DS) were evident, as well as significant differences in SPT. In fluent speakers, the left hemisphere may be marginally more excitable than the right one in motor thresholds at lower muscular activation, while active motor thresholds and SPT were higher in the left hemisphere of DS with respect to the right one, resulting also in a positive correlation with stuttering severity. Pre-TMS electromyography data gave overlapping evidence. Findings suggest the existence of a complex intracortical balance in DS tongue primary motor cortex, with a particular interplay between excitatory and inhibitory mechanisms, also in neural substrates related to silent periods. Findings are discussed with respect to functional and structural impairments in stuttering, and are also proposed as novel neural markers of a stuttering "state" in persistent DS, helping to define more focused treatments (e.g. neuro-modulation).

The aim of this study was to investigate the effect of the combined administration of intravenous immunoglobulins and steroids as a second-line therapy in 34 children with primary immune thrombocytopenia and persistent, symptomatic bleeding. Combined therapy (intravenous immunoglobulins 0.4 g/kg daily on days 1 and 2, and methylprednisolone 20 mg/kg daily on days 1-3) was administered to 12 patients with newly diagnosed ITP who did not respond to the administration of a single therapy (either intravenous immunoglobulins or steroids) and to 22 children with persistent and chronic disease who required frequent administrations (i.e. more frequently than every 30 days) of either immunoglobulins or steroids (at the same standard dosages) in order to control active bleeding. A response (i.e. platelet count >50×10(9)/L and remission of active bleeding) was observed in 8/12 (67%) patients with newly diagnosed ITP. The clinical presentation of responders and non-responders did not differ apparently. Patients in the chronic/persistent phase of disease had a significantly longer median period of remission from symptoms compared with the previous longest period of remission (p=0.016). The treatment was well tolerated. Our data suggest that the combined approach described is a well-tolerated therapeutic option for children with primary immune thrombocytopenia and persistent bleeding symptoms that can be used in both emergency and/or maintenance settings.

To evaluate survival time in dogs with persistent atrial standstill after pacemaker implantation and to compare the survival times for cardiac-related vs. non-cardiac deaths. Secondary objectives were to evaluate the effects of breed and the presence of congestive heart failure (CHF) at the time of diagnosis on survival time. Twenty dogs with persistent atrial standstill and pacemaker implantation. Medical records were searched to identify dogs diagnosed with persistent atrial standstill based on electrocardiogram that underwent pacemaker implantation. Survival after pacemaker implantation was analyzed using the Kaplan-Meier method. The median survival time after pacemaker implantation for all-cause mortality was 866 days. There was no significant difference (p=0.573) in median survival time for cardiac (506 days) vs. non-cardiac deaths (400 days). The presence of CHF at the time of diagnosis did not affect the survival time (P=0.854). No difference in median survival time was noted between breeds (P=0.126). Dogs with persistent atrial standstill have a median survival time of 866 days with pacemaker implantation, though a wide range of survival times was observed. There was no difference in the median survival time for dogs with cardiac-related deaths and those without. Patient breed and the presence of CHF before pacemaker implantation did not affect median survival time. Copyright © 2017 Elsevier B.V. All rights reserved.

Transjugular intrahepatic portosystemic shunt (TIPSS) is considered a valid therapeutic option for the treatment of portal hypertension and its complications. The guidelines for this procedure have already been established on the basis of the normal vascular anatomy and of various technical radiological aspects. In some few rare cases, diagnosis of a congenital vascular anomaly can be made accidentally by interventional radiologists, making the procedure of the TIPSS placement extremely difficult or in some cases technically impossible. This report describes a rare vascular malformation characterized by the absence of the right superior vena cava and persistence of the left superior vena cava in a patient with a diagnosis of advanced liver cirrhosis who needed a TIPSS placement in order to control refractory ascites.

The goal of this study was to analyze the persistence with antiepileptic drugs (AED) and associated factors in patients followed in neurological practices in Germany. This study included patients aged 18years or over who received two initial diagnoses of epilepsy and a first prescription of AED between 2007 and 2015 in a neurological practice (index date). The main outcome measure was the rate of AED persistence within five years of the index date. Kaplan-Meier analyses were performed to study treatment persistence as a function of age. A Cox proportional hazards regression model was used to estimate the relationship between non-persistence and demographic/clinical variables. A total of 8192 patients followed in neurological practices were included. After five years of follow-up, 41.1% (≤40years), 45.2%, (41-60years) and 50.1% (>60years) of patients followed in neurological practices were persistent (log-rank p-value<0.001). A negative association was found between discontinuation and age (≤40years vs. >60years: OR=1.19, 95% CI: 1.09-1.31; 41-60years vs. >60years: OR=1.10, 95% CI: 1.01-1.19). Furthermore, patients receiving old AED (OR=1.16, 95% CI: 1.01-1.34) or gabapentin (OR=1.46, 95% CI: 1.16-1.83) and those diagnosed with depression (OR=1.12, 95% CI: 1.03-1.21) were at a higher risk of non-persistence, whereas those receiving levetiracetam (OR=0.69, 95% CI: 0.60-0.80) or lamotrigine (OR=0.88, 95% CI: 0.79-0.97) and those with dementia (OR=0.74, 95% CI: 0.65-0.83) were at a lower risk. The rate of epilepsy patients persistent with AED was low after five years of treatment. Age, gender, co-morbidities, and drug characteristics were associated with this persistence.

AIM: To analyze electrocardiographic features of patients diagnosed with posttraumatic stress disorder (PTSD) after the Van-Erciş earthquake, with a shock measuring 7.2 on the Richter scale that took place in Turkey in October 2011. METHODS: Surface electrocardiograms of 12 patients with PTSD admitted to Van Erciş State Hospital (Van, Turkey) from February 2012 to May 2012 were examined. Psychiatric interviews of the sex and age matched control subjects, who had experienced the earthquake, confirmed the absence of any known diagnosable psychiatric conditions in the control group. RESULTS: A wide range of electrocardiogram (ECG) parameters, such as P-wave dispersion, QT dispersion, QT interval, Tpeak to Tend interval, intrinsicoid deflection durations and other traditional parameters were similar in both groups. There was no one with an abnormal P wave axis, short or long PR interval, long or short QT interval, negative T wave in lateral leads, abnormal T wave axis, abnormal left or right intrinsicoid deflection duration, low voltage, left bundle branch block, right bundle branch block, left posterior hemiblock, left or right axis deviation, left ventricular hypertrophy, right or left atrial enlargement and pathological q(Q) wave in either group. CONCLUSION: The study showed no direct effect of earthquake related PTSD on surface ECG in young patients. So, we propose that PTSD has no direct effect on surface ECG but may cause electrocardiographic changes indirectly by triggering atherosclerosis and/or contributing to the ongoing atherosclerotic process.

Persistently elevated natriuretic peptide (NP) levels in heart failure (HF) patients are associated with impaired prognosis. Recent work suggests that NP-guided therapy can improve outcome, but the mechanisms behind an elevated BNP remain unclear. Among the potential stimuli for NP in clinically stable patients are persistent occult fluid overload, wall stress, inflammation, fibrosis, and ischemia. The purpose of this study was to identify associates of B-type natriuretic peptide (BNP) in a stable HF population. In a prospective observational study of 179 stable HF patients, the association between BNP and markers of collagen metabolism, inflammation, and Doppler-echocardiographic parameters including left ventricular ejection fraction (LVEF), left atrial volume index (LAVI), and E/e prime (E/e') was measured. Univariable associates of elevated BNP were age, LVEF, LAVI, E/e', creatinine, and markers of collagen turnover. In a multiple linear regression model, age, creatinine, and LVEF remained significant associates of BNP. E/e' and markers of collagen turnover had a persistent impact on BNP independent of these covariates. Multiple variables are associated with persistently elevated BNP levels in stable HF patients. Clarification of the relative importance of NP stimuli may help refine NP-guided therapy, potentially improving outcome for this at-risk population.

Iconic memory is a high-capacity low-duration visual memory store that allows the persistence of a visual stimulus after its offset. The categorical nature of this store has been extensively debated. This study provides functional magnetic resonance imaging evidence for brain regions underlying the persistence of postcategorical representations of visual stimuli. In a partial report paradigm, subjects matched a cued row of a 3 × 3 array of letters (postcategorical stimuli) or false fonts (precategorical stimuli) with a subsequent triplet of stimuli. The cued row was indicated by two visual flankers presented at the onset (physical stimulus readout) or after the offset of the array (iconic memory readout). The left planum temporale showed a greater modulation of the source of readout (iconic memory vs. physical stimulus) when letters were presented compared to false fonts. This is a multimodal brain region responsible for matching incoming acoustic and visual patterns with acoustic pattern templates. These findings suggest that letters persist after their physical offset in an abstract postcategorical representation. A targeted region of interest analysis revealed a similar pattern of activation in the Visual Word Form Area. These results suggest that multiple higher-order visual areas mediate iconic memory for postcategorical stimuli. Copyright © 2012 Wiley Periodicals, Inc.

The effect of neck torsion on postural stability in subjects with persistent whiplash.

2011-08-01

Dysfunction of cervical receptors in neck disorders has been shown to lead to disturbances in postural stability. The neck torsion manoeuvre used in the smooth pursuit neck torsion (SPNT) test is thought to be a specific measure of neck afferent dysfunction on eye movement in those with neck pain. This study aimed to determine whether neck torsion could change balance responses in those with persistent whiplash-associated disorders (WADs). Twenty subjects with persistent WAD and 20 healthy controls aged between 18 and 50 years stood on a computerised force plate with eyes closed in comfortable stance under 5 conditions: neutral head, head turned to left and right and neck torsion to left and right. Root mean square (rms) amplitude of sway was measured in the anterior-posterior (AP) and medial-lateral (ML) directions. The whiplash group had significantly greater rms amplitude in the AP direction following neck torsion compared to the control group (p < 0.03). The results show that the neck torsion manoeuvre may lead to greater postural deficits in individuals with persistent WAD and provides further evidence of neck torsion to identify abnormal cervical afferent input, as an underlying cause of balance disturbances in WAD. Further research is warranted. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

Mitral regurgitation: anatomy is destiny.

PubMed

Athanasuleas, Constantine L; Stanley, Alfred W H; Buckberg, Gerald D

2018-04-26

Mitral regurgitation (MR) occurs when any of the valve and ventricular mitral apparatus components are disturbed. As MR progresses, left ventricular remodelling occurs, ultimately causing heart failure when the enlarging left ventricle (LV) loses its conical shape and becomes globular. Heart failure and lethal ventricular arrhythmias may develop if the left ventricular end-systolic volume index exceeds 55 ml/m2. These adverse changes persist despite satisfactory correction of the annular component of MR. Our goal was to describe this process and summarize evolving interventions that reduce the volume of the left ventricle and rebuild its elliptical shape. This 'valve/ventricle' approach addresses the spherical ventricular culprit and offsets the limits of treating MR by correcting only its annular component.

Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts), the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

2004-08-01

To determine the performance of a new NT-proBNP assay in comparison with brain natriuretic peptide (BNP) in identifying left ventricular systolic dysfunction (LVSD) in randomly selected community populations. Blood samples were taken prospectively in the community from 591 randomly sampled individuals over the age of 45 years, stratified for age and socioeconomic status and divided into four cohorts (general population; clinically diagnosed heart failure; patients on diuretics; and patients deemed at high risk of heart failure). Definite heart failure (left ventricular ejection fraction (LVEF) < 40%) was identified in 33 people. Samples were handled as though in routine clinical practice. The laboratories undertaking the assays were blinded. Using NT-proBNP to diagnose LVEF < 40% in the general population, a level of > 40 pmol/l had 80% sensitivity, 73% specificity, 5% positive predictive value (PPV), 100% negative predictive value (NPV), and an area under the receiver-operator characteristic curve (AUC) of 76% (95% confidence interval (CI) 46% to 100%). For BNP to diagnose LVSD, a cut off level of > 33 pmol/l had 80% sensitivity, 88% specificity, 10% PPV, 100% NPV, and AUC of 88% (95% CI 75% to 100%). Similar NPVs were found for patients randomly screened from the three other populations. Both NT-proBNP and BNP have value in diagnosing LVSD in a community setting, with similar sensitivities and specificities. Using a high cut off for positivity will confirm the diagnosis of LVSD but will miss cases. At lower cut off values, positive results will require cardiac imaging to confirm LVSD.

A 71-year-old man operated for a sigmoid tumour remained in the surveillance after adjuvant chemotherapy. After 3 years, a left axillary lymph node was visible on CT scan. The biopsy revealed a necrotising and abscessed granulomatous lymphadenitis, suggestive of cat scratch disease. The patient confirmed having been scratched by a cat and the serology for Bartonella henselae was IgM+/IgG-. Direct and culture examinations for tuberculosis were negative. The patient was treated for cat scratch disease. One year later, the CT scan showed increased left axillary lymph nodes and a left pleural effusion. Direct and cultural examinations to exclude tuberculosis were again negative. Interferon-γ release assay testing for tuberculosis was undetermined and then positive. Lymph node and pleural tuberculosis were diagnosed and treated with a good radiological response. This article has provides evidence of the importance of continued search for the right diagnosis and that two diagnoses can happen in the same patient.

Diagnosed with peripartum cardiomyopathy 8 years earlier, a 45-year-old female suffered sudden cardiac death. Following resuscitation, the patient was diagnosed with an anomalous origin of the left coronary artery from the pulmonary artery and underwent a successful coronary repair. The management of a patient with clinical features of cardiomyopathy is reviewed. Anomalous left coronary artery originating from the pulmonary artery (ALCAPA) is a rare but potentially lethal congenital anomaly affecting 1 in 300,000 live births 1 . Infants may have clinical features of myocardial ischemia and congestive heart failure 2 . Most surgically untreated patients die within the first year of life 3 . Although rare in teenagers and adults, this syndrome can cause sudden cardiac death 3 . ALCAPA that becomes clinically significant in the peripartum period and that is misdiagnosed for a postpartum cardiomyopathy, such as presented herein, is a very rare occurrence.

A 28-year-old man arrived for an outpatient cardiac MRI (CMR) study to evaluate cardiac structure. At the age of 24 the patient presented with acute onset expressive aphasia and was diagnosed with ischaemic stroke. Echocardiography at that time was reported as 'apical wall thickening consistent with apical hypertrophic cardiomyopathy'. CMR revealed a moderately dilated left ventricle with abnormal appearance of the left ventricular (LV) apical segments. Further evaluation was consistent with a diagnosis of LV non-compaction (LVNC) cardiomyopathy with a ratio of non-compacted to compacted myocardium measuring 3. There was extensive delayed hyperenhancement signal involving multiple segments representing a significant myocardial scar which is shown to have a prognostic role. Our patient, with no significant cerebrovascular risk factors, would likely have had an embolic stroke. This case demonstrates the role of CMR in accurately diagnosing LVNC in a patient with young stroke where prior echocardiography was non-diagnostic. 2014 BMJ Publishing Group Ltd.

A 15-month-old, spayed female, Bernese mountain dog was presented to the Institute of Small Animal Surgery at the University of Zurich because of chronic left forelimb lameness. The referring veterinarian diagnosed pain in the left shoulder region and had treated the dog with systemic non-steroidal anti-inflammatory drugs and restricted exercise for a two-week period. The follow-up examination revealed only minimal improvement and therefore, the dog was referred for further diagnostic evaluation. Chronic bicipital tenosynovitis and tendinitis of the infraspinatus muscle was diagnosed based on survey radiographs, arthrography, ultrasound, computed tomography (CT), and synovial fluid cytology. The dog underwent three sessions of extracorporeal shockwave therapy and substantial clinical improvement was observed. On follow-up examinations, only mild left forelimb lameness was evident following exercise, and changes in the intertubercular groove and at the supraglenoid tuberosity appeared less active on radiographs and CT. However, six months following treatment, mild degenerative joint disease was apparent.

Persistent müllerian duct syndrome is a rare form of male pseudohermaphroditism. A case is reported of normal male appearance with bilateral cryptorchidism and a right irreducible inguinal hernia. On exploration, an uterus with two fallopian tubes and a testicle were found in the hernia sac. The uterus, fallopian tubes and left testicle were en bloc removed. Right orchidopexy and hernia repair were performed. In conclusion, if there is an adult bilateral cryptorchidism, surgeons should take into consideration a persistent müllerian duct syndrome.

The most common venous abnormality of the thorax is persistent left superior vena cava (PLSVC), incidence being less than 0.5%. However, with congenital heart disease, it is about 6.1%. When the coronary sinus is dilated always search for PLSVC. The coronary sinus may communicate with the left atrium. This is known as an unroofed coronary sinus (UCS) and preoperatively documenting it is important. Of all the congenital cardiac anomalies, the sinus venosus defect (SVD) type of atrial septal defect (ASD) is most commonly associated with PLSVC and accounts for 4–11% of all ASDs. Multidetector CT can easily show all these abnormalities along with haemodynamics. On transoesophageal echocardiography it is difficult to characterise SVD and visualise a coronary sinus because of a limited window, contrast resolution and poor patient compliance. The complex of UCS and PLSVC is one such abnormality and its treatment requires careful assessment of other concomitant cardiac abnormalities to prevent post-treatment haemodynamic complications.

To explain gating of memory encoding, magnetoencephalography (MEG) was analyzed over multi-regional network of negative correlations between alpha band power during cue (cue-alpha) and gamma band power during item presentation (item-gamma) in Remember (R) and No-remember (NR) condition. Persistent homology with graph filtration on alpha-gamma correlation disclosed topological invariants to explain memory gating. Instruction compliance (R-hits minus NR-hits) was significantly related to negative coupling between the left superior occipital (cue-alpha) and the left dorsolateral superior frontal gyri (item-gamma) on permutation test, where the coupling was stronger in R than NR. In good memory performers (R-hits minus false alarm), the coupling was stronger in R than NR between the right posterior cingulate (cue-alpha) and the left fusiform gyri (item-gamma). Gating of memory encoding was dictated by inter-regional negative alpha-gamma coupling. Our graph filtration over MEG network revealed these inter-regional time-delayed cross-frequency connectivity serve gating of memory encoding. PMID:28169281

Children diagnosed with Disruptive Behavior Disorders (DBD), especially those with psychopathic traits, are at risk of developing persistent and severe antisocial behavior. Deficient fear conditioning may be a key mechanism underlying persistence, and has been associated with altered regional brain function in adult antisocial populations. In this study, we investigated the associations between the neural correlates of fear conditioning, persistence of childhood-onset DBD during adolescence and psychopathic traits. From a cohort of children arrested before the age of 12 years, participants who were diagnosed with Oppositional Defiant Disorder or Conduct Disorder in previous waves (mean age of onset 6.5 years, s.d. 3.2) were reassessed at mean age 17.6 years (s.d. 1.4) and categorized as persistent (n=25) or desistent (n=25) DBD. Using the Youth Psychopathic Traits Inventory and functional magnetic resonance imaging during a fear conditioning task, these subgroups were compared with 26 matched healthy controls from the same cohort. Both persistent and desistent DBD subgroups were found to show higher activation in fear processing-related brain areas during fear conditioning compared with healthy controls. In addition, regression analyses revealed that impulsive-irresponsible and grandiose-manipulative psychopathic traits were associated with higher activation, whereas callous-unemotional psychopathic traits were related to lower activation in fear-related areas. Finally, the association between neural activation and DBD subgroup membership was mediated by impulsive-irresponsible psychopathic traits. These results provide evidence for heterogeneity in the neurobiological mechanisms underlying psychopathic traits and antisocial behavior and, as such, underscore the need to develop personalized interventions.

Pemphigus vulgaris is an autoimmune blistering disease that commonly involves the scalp. Lesions of pemphigus vulgaris that persist on the scalp for a long period may be accompanied by tufted hair folliculitis. Only two previous accounts of tufted hair folliculitis developing in a lesion of pemphigus vulgaris have been reported. We report a 51-year-old-man with erosions and clusters of hair on the scalp. The scalp lesion had persisted for about 20 years. A histopathological examination of the skin lesion on the scalp revealed separation of the epidermis and clusters of several adjacent hair follicles. The patient was diagnosed with persistent pemphigus vulgaris of the scalp showing features of tufted hair folliculitis. PMID:22148026

A 10 week old female intact Staffordshire terrier was presented with a total of five congenital cardio-thoracic vascular anomalies consisting of a patent ductus arteriosus (PDA) with an aneurysmic dilation, pulmonic stenosis, persistent right aortic arch, aberrant left subclavian artery and persistent left cranial vena cava. These abnormalities were identified with a combination of echocardiogram and computed tomography angiography (CTA). The abnormalities were associated with esophageal entrapment, regurgitation, and volume overload of the left heart with left atrial and ventricular enlargement. A 2 cm diameter aneurysmic dilation at the junction of the PDA, right aortic arch and aberrant left subclavian artery presented an unusual surgical challenge and precluded simple circumferential ligation and transection of the structure. A full scale three dimensional model of the heart and vasculature was constructed from the CTA and plasma sterilized. The model was used preoperatively to facilitate surgical planning and enhance intraoperative communication and coordination between the surgical and anesthesia teams. Intraoperatively the model facilitated spatial orientation, atraumatic vascular dissection, instrument sizing and positioning. A thoracoabdominal stapler was used to close the PDA aneurysm prior to transection. At the four-month postoperative follow-up the patient was doing well. This is the first reported application of new imaging and modeling technology to enhance surgical planning when approaching correction of complex cardiovascular anomalies in a dog.

2014-01-01

Objective This study aimed to assess the strengths and difficulties in word and pseudoword writing in adults with left- and right-hemisphere strokes, and discuss the profiles of acquired dysgraphia in these individuals. Methods The profiles of six adults with acquired dysgraphia in left- or right-hemisphere strokes were investigated by comparing their performance on word and pseudoword writing tasks against that of neurologically healthy adults. A case series analysis was performed on the patients whose impairments on the task were indicative of acquired dysgraphia. Results Two patients were diagnosed with lexical dysgraphia (one with left hemisphere damage, and the other with right hemisphere damage), one with phonological dysgraphia, another patient with peripheral dysgraphia, one patient with mixed dysgraphia and the last with dysgraphia due to damage to the graphemic buffer. The latter patients all had left-hemisphere damage (LHD). The patterns of impairment observed in each patient were discussed based on the dual-route model of writing. Conclusion The fact that most patients had LHD rather than right-hemisphere damage (RHD) highlights the importance of the former structure for word processing. However, the fact that lexical dysgraphia was also diagnosed in a patient with RHD suggests that these individuals may develop writing impairments due to damage to the lexical route, leading to heavier reliance on phonological processing. Our results are of significant importance to the planning of writing interventions in neuropsychology. PMID:29213909

This case report describes the use of neuropsychological testing to Iocalize and diagnose lesions The testing was instrumental in disentangling contradictory symptoms to reveal a Kernohan's notch (later confirmed by MRI), thus ruling out incorrect diagnoses We describe the case of a 36-year-old right-handed man who developed a left epidural hematoma after suffering head trauma from a blunt instrument Sequelae 2 months post-injury included left hemiparesis (ipsilateral to the lesion), dysphonic speech, severe naming/word-finding deficits, and severe memory impairment This patient's symptom pattern presented somewhat of a mystery as his cognitive deficits appeared consistent with left hemisphere damage, while his left motor symptoms suggested right hemisphere damage Medical records were inconsistent Deficits on neuropsychological testing at 3 months post-injury included impairment in verbal and visual memory, confrontation naming, and left-sided motor function Attention, visual-spatial skills, nonverbal problem solving, and right motor speed and coordination were intact A herniation syndrome, Kernohan's notch, was considered to be the most likely explanation This phenomenon occurs when a mass occupying lesion causes significant midline shift of the midbrain, pressing the contralateral cerebral peduncle against the tentorium This pressure produces an ischemic infact in the region of the corticospinal (motor) pathways Subsequent MRI confirmed a lesion in the right cerebral crus The pattern of neuropsychological finding in this patient is discussed.

Abstract Background: Dextrocardia, or right-lying heart, is an uncommon congenital heart disease in which the apex of the heart is located on the right side of chest. Persistent left superior vena cava (PLSVA) is a rare venous anomaly that is often associated with the abnormalities of cardiac transduction system. A case with combination of dextrocardia, persistent left superior vena cava, and sick sinus syndrome has not been reported. Methods: We used different techniques including cardiac color Doppler echocardiography, 24-hour Holter monitoring, and abdominal ultrasound to make a diagnosis and treated the patient by implanting a VVI pacemaker. Results: A 50-year-old woman was admitted with a syncope. Angiography of the right atrium and superior vena cava, echocardiography, electrocardiography, and abdominal ultrasound revealed the presence of the combination of mirror image dextrocardia, PLSVA, and sick sinus syndrome. The complex structural anomalies presented great technical challenges for interventional treatments. After thorough examination and understanding of the structural anatomy and anomalies of the superior and inferior vena cava and cardiac chambers, we successfully treated this patient by implanting a VVI pacemaker. Conclusion: Physicians must be aware of the complexity of the morphological and anatomical structures of dextrocardia accompanying PLSVC. Given that the diagnosis of situs inversus was performed at a relatively advanced age, it is therefore important to make such a correct diagnosis followed by appropriate therapeutic intervention.

Recovery of injured AF in patients with traumatic brain injury (TBI) has not been reported. In this study, we report on a patient with TBI who recovered from an injury to Broca's portion of AF in the dominant hemisphere, diagnosed by diffusion tensor tractography (DTT). A 28-year-old right-handed male patient suffered head trauma resulting from sliding while riding a motorcycle. He was diagnosed with a traumatic contusional hemorrhage in the left frontal lobe, subarachnoid hemorrhage, and subdural hemorrhage in the left fronto-temporal lobe. He underwent craniectomy on the left fronto-temporal area, and hematoma removal for the subdural hemorrhage in the neurosurgery department of a university hospital. Two weeks after the injury, he was transferred to the rehabilitation department of another university hospital. He showed severe aphasia and brain MRI showed leukomalactic lesion in the left frontal lobe. The result WAB for the patient showed severe aphasia, with an aphasia quotient of 45.3 percentile. However, his aphasia improved rapidly by 9 months with an aphasia quotient at the 100.0 percentile. 2-week DTT detected discontinuity in the subcortical white matter at the branch to Broca's area of left AF. By contrast, on 9-month DTT, the discontinued portion of left AF was elongated to the left Broca's area. Recovery of injured Broca's portion of AF in the dominant hemisphere along with excellent improvement of aphasia was demonstrated in a patient with TBI. This study has important implications in brain rehabilitation because the mechanism of recovery from aphasia following TBI has not been elucidated. Copyright © 2017 The Authors.

A Case of Bariatric Surgery-related Wernicke-Korsakoff Syndrome with Persisting Anterograde Amnesia.

PubMed

Gasquoine, Philip Gerard

2017-08-01

To describe the theoretical and clinical implications of the neuropsychological evaluation of a case of bariatric surgery-related Wernicke-Korsakoff syndrome. The patient was a 37-year old, female, bilingual, bachelor's degree educated, Mexican American public relations consultant without preexisting psychiatric, neurological, or substance abuse history. Recovery from laparoscopic sleeve gastrectomy surgery for morbid obesity was complicated by intraabdominal abscess, multibacterial infection, and prolonged nausea and vomiting. About 15 weeks post-surgery she was diagnosed with Wernicke's encephalopathy. She had a positive response to thiamine supplement but was left with persisting self-reported memory problems that were confirmed by family members. Multiple neuroimaging studies were all normal. A neuropsychological evaluation at 14 months post-surgery revealed anterograde amnesia for verbal and visual-perceptual material. There was no clear period of temporally graded retrograde amnesia. Scores on tests of visual-perceptual, language, fine motor, and executive functions were unimpaired. She had awareness of her neurocognitive impairment, but did not exhibit emotional distress. Follow-up neuropsychological evaluation at 17 months showed a similar neurocognitive profile with increased emotional distress. Her preserved executive functioning is theoretically important as it supports arguments that such impairment in alcohol use-related Korsakoff syndrome derives from the toxic effects of the prolonged misuse of alcohol and not vitamin deficiency. From a clinical perspective, neuropsychological evaluation of thiamine treated, bariatric surgery-related, Wernicke's encephalopathy cases is indicated if there is suspicion of residual memory impairment. © The Author 2017.

On tests of design fluency, an examinee draws as many different designs as possible in a specified time limit while avoiding repetition. The neuroanatomical substrates and diagnostic group differences of design fluency repetition errors and total correct scores were examined in 110 individuals diagnosed with dementia, 53 with mild cognitive impairment (MCI), and 37 neurologically healthy controls. The errors correlated significantly with volumes in the right and left orbitofrontal cortex (OFC), the right and left superior frontal gyrus, the right inferior frontal gyrus, and the right striatum, but did not correlate with volumes in any parietal or temporal lobe regions. Regression analyses indicated that the lateral OFC may be particularly crucial for preventing these errors, even after excluding patients with behavioral variant frontotemporal dementia (bvFTD) from the analysis. Total correct correlated more diffusely with volumes in the right and left frontal and parietal cortex, the right temporal cortex, and the right striatum and thalamus. Patients diagnosed with bvFTD made significantly more repetition errors than patients diagnosed with MCI, Alzheimer's disease, semantic dementia, progressive supranuclear palsy, or corticobasal syndrome. In contrast, total correct design scores did not differentiate the dementia patients. These results highlight the frontal-anatomic specificity of design fluency repetitions. In addition, the results indicate that the propensity to make these errors supports the diagnosis of bvFTD. (JINS, 2012, 18, 1-11).

We report 2 cases of persistent urogenital sinus (UGS) with duplication of the bladder and vagina in different planes. Cystoscopy and vaginoscopy were used to diagnose persistent UGS with bladder and vaginal duplication in 2 infants with recurrent urinary tract infection. Surgical repair was done by way of a midline abdominal and perineal approach using tubularized UGS to reconstruct the urethra. Persistent UGS represents a major anomaly; these patients had the added complexity of duplication of the bladder and vagina. In these complex patients, the true anatomy may only become apparent during the surgical reconstruction, necessitating a flexible, individual approach.

Left ventricular hypertrophy diagnosed after a stroke: a case report.

Stroke is a recognized clinical course of hypertrophic cardiomyopathy. This interesting case showed notable difference on the electrocardiogram of a patient 4 months prior to suffering a stroke and 10 days after suffering a stroke. The pre-stroke electrocardiogram showed atrial fibrillation with a narrow QRS complex, while the post-stroke electrocardiogram showed marked left ventricular hypertrophy. Left ventricular hypertrophy was diagnosed using the Sokolow-Lyon indices. The development of left ventricular hypertrophy a few days after suffering a stroke has not previously been reported. An 83-year-old white British woman with a background history of permanent atrial fibrillation, hypertension, and previous stroke attended the emergency department with a 2-day history of exertional dyspnea, and chest tightness. On examination, she had bibasal crepitations with a systolic murmur loudest at the apex. In-patient investigations include an electrocardiogram, blood tests, chest X-ray, contrast echocardiogram, coronary angiogram, and cardiovascular magnetic resonance imaging. An electrocardiogram showed atrial fibrillation, with inferolateral T wave inversion, and left ventricular hypertrophy. A chest X-ray showed features consistent with pulmonary edema. A contrast echocardiogram showed marked hypertrophy of the mid to apical left ventricle, appearance consistent with apical hypertrophic cardiomyopathy. Coronary angiography showed eccentric shelf-type plaque with non-flow-limiting stenosis in the left coronary artery main stem. Cardiovascular magnetic resonance imaging reported findings highly suggestive of apical hypertrophic cardiomyopathy. Our patient was treated and discharged on rivaroxaban, bisoprolol, and atorvastatin with a follow-up in the cardiomyopathy outpatient clinic. Electrocardiogram diagnosis of left ventricular hypertrophy led to the diagnosis of apical hypertrophic cardiomyopathy in this patient. Left ventricular hypertrophy was only evident a few days after our patient suffered a stroke. The underlying mechanisms responsible for this remain unclear. Furthermore, differential diagnosis of hypertrophic cardiomyopathy should be considered in people with electrocardiogram criteria for left ventricular hypertrophy. Cardiovascular magnetic resonance imaging is an important diagnostic tool in identifying causes of left ventricular hypertrophy. Family screening should be recommended in patients with new diagnosis of hypertrophic cardiomyopathy.

Cushing Syndrome is difficult to diagnose, and the comorbidities and persistent late effects of hypercortisolemia after treatment of the primary disease are challenging for the patient and the endocrinologist. To report the case of a girl with obesity and hypertension, ultimately diagnosed with Cushing syndrome due to primary pigmented nodular adrenocortical disease. In this case, the complications of hypercortisolism persisted short term despite surgical intervention. A 4 year old morbidly obese African-American girl with developmental delay presented with hypertensive emergency in the ER and 18-month history of progressive weight gain. Her previous history included premature adrenarche, hypertension, seizures and a random high cortisol with suppressed ACTH. She was subsequently stabilized, and a diagnostic work-up persistently demonstrated elevated cortisol and suppressed ACTH. An abdominal MRI showed bilateral adrenal multinodular disease, consistent with multinodular hyperplasia of the adrenal glands. Based on these findings the patient underwent a bilateral adrenalectomy, which confirmed primary pigmented nodular adrenocortical disease. The patient had a complicated, protracted post-operative course requiring adjustment of therapy for persistent hypertension. Two months after surgery, she was readmitted to the Emergency Department with hyperpyrexia and hypertension and succumbed to the complications of sepsis. This case highlights the significant diagnostic and therapeutic challenges in treating children with Cushing syndrome. Resolution of the source of hypercortisolemia does not imply regression of hypertension or recovery of the immune system. Although the child underwent bilateral adrenalectomy, persistent consequences of prolonged severe hypercortisolism contributed to her death two months later.

Background The aim of this study was to investigate the effect of the combined administration of intravenous immunoglobulins and steroids as a second-line therapy in 34 children with primary immune thrombocytopenia and persistent, symptomatic bleeding. Materials and methods Combined therapy (intravenous immunoglobulins 0.4 g/kg daily on days 1 and 2, and methylprednisolone 20 mg/kg daily on days 1–3) was administered to 12 patients with newly diagnosed ITP who did not respond to the administration of a single therapy (either intravenous immunoglobulins or steroids) and to 22 children with persistent and chronic disease who required frequent administrations (i.e. more frequently than every 30 days) of either immunoglobulins or steroids (at the same standard dosages) in order to control active bleeding. Results A response (i.e. platelet count >50×109/L and remission of active bleeding) was observed in 8/12 (67%) patients with newly diagnosed ITP. The clinical presentation of responders and non-responders did not differ apparently. Patients in the chronic/persistent phase of disease had a significantly longer median period of remission from symptoms compared with the previous longest period of remission (p=0.016). The treatment was well tolerated. Discussion Our data suggest that the combined approach described is a well-tolerated therapeutic option for children with primary immune thrombocytopenia and persistent bleeding symptoms that can be used in both emergency and/or maintenance settings.

A 12-year-old boy reported in outpatient department with history of shortness of breath and dyspnoea on moderate exertion. Physical examination was significant for bounding pulses and for a continuous murmur III/VI, best heard at the left upper sternal border. Echocardiography confirmed a large patent arterial duct with shortening fraction of 33%. He underwent successful transcatheter closure of the patent arterial, using Amplatzer duct occluder 12/10. Few hours later echocardiography revealed an unexpected, yet important depression of left ventricular systolic function with shortening fraction decreasing to 24% and then two weeks later decreasing further to 20%. At a follow-up after four months, he had improved clinically but left ventricular dysfunction still persisted with shortening fraction of 24%.

We present a patient with persistent bilateral megalocystic ovaries following in vitro fertilization which was detected during cesarean section. A 24 year-old primigravida presented to our clinic at the 36(th) week of a twin pregnancy with labour pain and cervical dilatation. On ultrasound examination, 2 masses of 90×60 and 60×70 mm were seen in the right and left adnexal regions respectively. Her history showed that she had unexplained infertility for 4 years and had undergone IVF with gonadotropin releasing hormone (GnRH)-agonist stimulation. Two embryos were transferred. Twin pregnancy was detected on ultrasound examination. The patient was delivered by emergency caesarean section due to transverse presentations at 36(th) weeks of gestation. During the operation, both adnexae were markedly enlarged, the right ovary measuring about 15×18 cm and the left about 16×18 cm. There was minimal ascites in the abdominal cavity. Ovarian biopsy was performed and the final pathology report showed bilateral follicle cysts. The patient was discharged on the postoperative 4(th) day. The patient was seen 4 weeks later. She had no complaints and ultrasound follow-up revealed a normal size uterus and ovaries. We should keep in mind that hyperstimulated, enlarged ovaries and its complication may be seen in the late weeks of pregnancy, even at term, in cases of in vitro fertilization cases. Therefore, close follow-up of pregnant IVF patints is recommended whether they had OHSS or not, because ovarian torsion caused by hyperstimulated ovaries may be difficult to diagnose during pregnancy.

The aim of this study was to assess the left ventricular (LV) remodeling response to chemotherapy in low-cardiac-risk women with newly diagnosed nonmetastatic breast cancer. Cardiotoxic effects of chemotherapy are an increasing concern. To effectively interpret cardiac imaging studies performed for screening purposes in patients undergoing cancer therapy it is necessary to understand the normal changes in structure and function that may occur. Twenty women without preexisting cardiovascular disease, of a mean age of 50 years, newly diagnosed with nonmetastatic breast cancer and treated with anthracycline or trastuzumab, were prospectively enrolled and evaluated at four time points (at baseline, during chemotherapy, 2 weeks after chemotherapy, and 6 months after chemotherapy) using cardiac magnetic resonance imaging, blood samples, and a clinical questionnaire. Over a 6-month period, the left ventricular ejection fraction (%) decreased (64.15±5.30 to 60.41±5.77, P<0.002) and the LV end-diastolic (mm) and end-systolic (mm) volumes increased (124.73±20.25 to 132.21±19.33, P<0.04 and 45.16±11.88 to 52.57±11.65, P<0.00, respectively). The LV mass (g) did not change (73.06±11.51 to 69.21±15.3, P=0.08), but the LV mass to LVEDV ratio (g/mm) decreased (0.594±0.098 to 0.530±0.124, P<0.04). In low-cardiac-risk women with nonmetastatic breast cancer, the increased LV volume and a mildly decreased left ventricular ejection fraction during and after chemotherapy do not seem to be associated with laboratory or clinical evidence of increased risk for heart failure.

A proof of concept is demonstrated with the Geophysical Fluid Dynamics Laboratory AM4 and Community Earth System Model 1.2.2 climate models. Instead of prescribing atmospheric conditions and aerosols, as in prior intercomparisons, native snapshots of the atmospheric state and aerosol optical properties from the participating models are used as inputs to an accurate radiation solver to uncover model-relevant biases. Thesemore » diagnostic results show that the models' aerosol IRE bias is of the same magnitude as the persistent range cited (~1 W/m 2) and also varies spatially and with intrinsic aerosol optical properties. The findings presented here underscore the significance of native model error analysis and its dispositive ability to diagnose global biases, confirming its fundamental value for the Radiative Forcing Model Intercomparison Project.« less

Sinus of valsalva aneurysm is a rare condition arising from any of the three aortic sinuses. Among them, an aneurysm arising from the left coronary sinus is the rarest. Most of these cases were earlier diagnosed using echocardiography and conventional angiography. But with the availability of advanced imaging modalities like 64 slice cardiac CT and MR modalities, this condition can be accurately assessed noninvasively. We report a case of ruptured aneurysm originating from the left coronary sinus with a long windsock type of fistulous track between the aneurysm and right atrium evaluated by 64 slice cardiac CT imaging. This was later confirmed perioperatively.

Objectives To better understand the natural history and spectrum of fetal aortic stenosis (AS), we aimed to 1) determine the prenatal diagnosis rate of neonates with critical AS and a biventricular (BV) outcome; and 2) describe the findings at fetal echocardiography in prenatally diagnosed patients. Methods A multi-center, retrospective study was performed from 2000 to 2013. Neonates with critical AS who were discharged with a BV outcome were included. The prenatal diagnosis rate was compared to that reported for hypoplastic left heart syndrome (HLHS). Fetal echocardiographic findings in prenatally diagnosed patients were reviewed. Results Only 10 of 117 neonates (8.5%) with critical AS and a BV outcome were diagnosed prenatally, a rate significantly lower than that for HLHS in the contemporary era (82%; p<0.0001). Of the 10 patients diagnosed prenatally, all developed LV dysfunction by a median gestational age of 33 weeks (range, 28–35). When present, Doppler abnormalities such as retrograde flow in the aortic arch (n=2), monophasic mitral inflow (n=2), and left to right flow across the foramen ovale (n=8) developed late in gestation (median 33 weeks). Conclusion The prenatal diagnosis rate among neonates with critical AS and a BV outcome is very low, likely due to a relatively normal 4-chamber view in mid-gestation with development of significant obstruction in the 3rd trimester. This natural history contrasts with that of severe mid-gestation AS with evolving HLHS and suggests that the timing in gestation of significant AS has an important impact on subsequent left heart growth in utero.

Complications arising from a misdiagnosed giant lipoma of the hand and palm: a case report

PubMed Central

2011-01-01

Introduction Lipomas are benign tumors which may appear in almost any human organ. Their diagnosis rate in the hand region is not known. Case Presentation We present the case of a 63-year-old Greek Caucasian woman with a giant lipoma of the hand and palm which was not initially diagnosed. After repeated surgical decompression of the carpal tunnel the patient was referred with persisting symptoms of median and ulnar nerve compression and a prominent mass of her left palm and thenar eminence. Clinical examination, magnetic resonance imaging, nerve conduction study and biopsy, revealed a giant lipoma in the deep palmar space (8.0 × 4.0 × 3.75 cm), which was also infiltrating the carpal tunnel. She had already undergone two operations for carpal tunnel syndrome with no relief of her symptoms and she also ended up with a severed flexor pollicis longus tendon. Definitive treatment was performed by marginal resection of the lipoma and restoration of the flexor pollicis longus with an intercalated graft harvested from the palmaris longus. Thirty months after surgery the patient had a fully functional hand without any neurological deficit. Conclusion Not all lipomas of the wrist and hand are diagnosed. Our report tries to emphasize the hidden danger of lipomas in cases with carpal tunnel symptoms. The need for a high index of suspicion in conjunction with good clinical evaluation and the use of appropriate investigative studies is mandatory in order to avoid unnecessary operations and complications. Marginal excision of these tumors is restorative. PMID:22085433

A 55-year-old man was diagnosed with remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome. Contrast-enhanced computed tomography for cancer screening showed a mass with low-density centers with an enhanced rim in the left iliopsoas muscle. We suspected an iliopsoas abscess and performed computed-tomography-guided puncture of the mass. Both Gram staining and the culture of the fluid were negative. We diagnosed the patient with RS3PE syndrome with iliopsoas bursitis and administered low-dose corticosteroids without antibiotics. The symptoms, including left hip pain, quickly disappeared following treatment. Clinicians should be aware that iliopsoas bursitis may resemble an iliopsoas abscess. As a result, it is important to make an accurate differential diagnosis.

To explore changes in healthcare professionals' views about the diagnosis and management of heart failure since a study in 2003. Focus groups and a national online cross-sectional survey. Focus groups (n=8 with a total of 56 participants) were conducted in the North East of England using a phenomenological framework and purposive sampling, informing a UK online survey (n=514). 4 categories were identified as contributing to variations in the diagnosis and management of heart failure. Three previously known categories included: uncertainty about clinical practice, the value of clinical guidelines and tensions between individual and organisational practice. A new category concerned uncertainty about end-of-life care. Survey responses found that confidence varied among professional groups in diagnosing left ventricular systolic dysfunction (LVSD): 95% of cardiologists, 93% of general physicians, 66% of general practitioners (GPs) and 32% of heart failure nurses. For heart failure with preserved ejection fraction (HFpEF), confidence levels were much lower: 58% of cardiologists, 43% of general physicians, 7% of GPs and 6% of heart failure nurses. Only 5-35% of respondents used natriuretic peptides for LVSD or HFpEF. Confidence in interpreting test findings was fundamental to the use of all diagnostic tests. Clinical guidelines were reported to be helpful when diagnosing LVSD by 33% of nurses and 50-56% of other groups, but fell to 5-28% for HFpEF. Some GPs did not routinely initiate diuretics (23%), ACE-inhibitors (22%) or β-blockers (38%) for LVSD for reasons including historical teaching, perceived side effects and burden of monitoring. For end-of-life care, there was no consensus about responsibility for heart failure management. Reported differences in the way heart failure is diagnosed and managed have changed little in the past decade. Variable access to diagnostic tests, modes of care delivery and non-uniform management approaches persist. The current National Health Service (NHS) context may not be conducive to addressing these issues.

Persistent auditory verbal hallucination is a clinically significant problem in schizophrenia. Recent studies suggest a promising role for add-on transcranial direct current stimulation (tDCS) in treatment. An optimised version of tDCS, namely high-definition tDCS (HD-tDCS), uses smaller electrodes arranged in a 4x1 ring configuration and may offer more focal and predictable neuromodulation than conventional tDCS. This case report illustrates the feasibility and clinical utility of add-on HD-tDCS over the left temporoparietal junction in a 4x1 ring configuration to treat persistent auditory verbal hallucination in schizophrenia.

The study was designed to examine the effect of persistent temporomandibular joint (TMJ) inflammation on neuronal activation in the descending pain modulatory system in response to noxious stimulus. Formalin was injected into the left masseter muscle or hindpaw of rats 10 days after injection of the left TMJ with saline or complete Freund's adjuvant (CFA). The results showed that 10-day persistent TMJ inflammation (induced by CFA) alone did not induce a significant increase in Fos-like immunoreactive (Fos-LI) neurons in the rostral ventromedial medulla (RVM) or locus coeruleus (LC), but that formalin injection of the masseter muscle or hindpaw induced a significant increase in Fos-LI neurons in the RVM and LC of rats with and without TMJ inflammation (P < 0.05). However, persistent TMJ inflammation significantly increased Fos-LI neurons in the nucleus raphe magnus (NRM) induced by subsequent formalin injection of the masseter muscle and hindpaw (70.2% increase and 53.8% increase, respectively, over the control TMJ-saline-injected rats; P < 0.05). The results suggest that persistent TMJ inflammation increases neuronal activity, in particularly in the NRM, by the plastic change of the descending pain modulatory system after ipsilateral application of a noxious stimulus to either orofacial area or a spatially remote body area.

Erythema nodosum leprosum (ENL) or Type-2 Lepra reaction is a manifestation of type III hypersensitivity response and usually occurs in certain cases of lepromatous and borderline lepromatous leprosy. It is usually generalized and evanescent, and responds well to oral corticosteroid therapy. Here we report an unusual case of persistent and localized ENL in a 19-year-old girl, which could be diagnosed with the aid of skin biopsy and histopathological examination.

We report on a 42-year-old woman who presented with persistent pain in her left knee with no history of trauma. Sagittal T1-weighted MRI of the left knee showed discontinuity between the anterior and posterior horns of the left medial meniscus, causing effectively the development of degenerative lesion of the posterior horn. The latter was correlated to varus deformity of the left lower extremity associated with subsequent narrowing of the medial knee joint. The unusual craniofacial contour of the patient, the skeletal survey and the elevated serum alkaline phosphatase were compatible with the diagnosis of Paget's disease of the bone. To alleviate the adverse effect of the mal-alignment of the left femur onto the left knee, corrective osteotomy of the left femoral diaphysis by means of fixators was performed. To the best of our knowledge this is the first clinical report describing the management and the pathological correlation of a unilateral varus deformity of the femoral shaft and degenerative lesions of the left knee in a patient with Paget's disease of the bone.

The occurrence of hepatic artery aneurysms is rare and might be incidentally diagnosed, as the patient remains asymptomatic for a long period of time. However, due to the fact that these lesions are associated with a high risk of developing life threatening complications, such as intraperitoneal rupture, it has been stated that all cases should be submitted to treatment by endovascular or surgical approach. We present the case of a 68-year-old patient, who presented with recurrent upper digestive tract bleedings and was diagnosed with a large aneurysm of the common and the proper hepatic artery, and the gastroduodenal artery. The preoperative angiography revealed an anatomic variation consisting of the common hepatic artery originating from the celiac trunk, and the left hepatic artery originating from the left gastric artery. A percutaneous right portal vein embolization was performed in order to induce hypertrophy of the left lobe and prepare the patient for a right hepatectomy and aneurysmal resection. However, at the time of surgery, after performing the aneurysmal resection and arterial ligation, the vascular supply of the entire liver was efficiently provided by the left hepatic artery and its collaterals. Concluding, hepatic resection was no longer necessary. Copyright© 2017, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.

Giant cell myocarditis (GCM) is a rare but fatal disease of idiopathic origin. It results in focal necrosis of myocardium. This is a case report of middle aged Malaysian Indian female who died due to cardiac tamponade due to rupture myocardium and tear in the root of aorta. On naked eye examination, it simply resembled as recent as well as old fibrotic areas of myocardial infarction. She was clinically diagnosed as a case of obstructive cardiomyopathy with atrioventricular block, and was on pace maker. There was subendocardial fibrosis and left ventricular transmural infarction in the left ventricle. On histopathology, this was diagnosed as GCM, there were widespread areas of inflammatory cellular infiltration within the myocardium with multinucleated giant cells and granulomas interspersed with lymphocytes. Microscopic field showed up to 10 multinucleated giant cells. In this case, there were focal areas at multiple locations and caused uneven thickness in the left ventricle wall. Idiopathic GCM is very rare and causation of hemopericardium is the unique feature of this case. In this case the direct link of GCM with aortitis and rupture of left ventricle wall resulting in hemopericardium is shown. This case is documented through macroscopic as well as microscopic photographs in H&E, Ziel-Nelson, and GMS staining.

The neural correlates of stimulus-driven processes, such as response preparation, have been posited to be associated with the onset of attention deficit hyperactivity disorder (ADHD) while being distinct from the neural mechanisms associated with recovery. The authors tested this hypothesis in adults with remitted and persistent ADHD. Thirty-eight young adults who were diagnosed with combined-type ADHD in childhood (probands) and 32 carefully matched comparison subjects were followed longitudinally and scanned with functional MRI while performing an event-related cued reaction time task. Probands were characterized as individuals with persistent or remitted ADHD. Differences in thalamo-cortical activation and functional connectivity during response preparation between comparison subjects and probands and between individuals with persistent ADHD and those with remitted ADHD were assessed by contrasting neural activation and functional connectivity during cue or noncue events. Probands exhibited less cue-related activation than comparison subjects in the thalamus, anterior cingulate cortex, supplementary motor area, inferior parietal lobe, and dorsolateral prefrontal cortex despite similar overall patterns of activation. There were no differences in activation between individuals in the remitted ADHD group and those in the persistent ADHD group in any hypothesized regions. However, cue-related functional connectivity between the right thalamus and brainstem was greater in comparison subjects relative to probands, and cue-related connectivity was greater between the right thalamus and prefrontal regions in individuals with remitted ADHD relative to those with persistent ADHD. Decreased thalamo-cortical activation during response preparation was present in adults diagnosed with ADHD in childhood regardless of symptom remission in adulthood, and may be partly driven by less functional coordination between the brainstem and thalamus. Greater functional integration of the thalamo-cortical network might parallel symptom recovery.

Permanent right ventricular pacing through an anomalous left superior vena cava.

A persistent left superior vena cava can complicate the implantation of a transvenous pacemaker. In a patient who required a permanent pacemaker, this venous anomaly was discovered during the insertion of the electrode but it did not prevent long-term right ventricular pacing. This was achieved after the electrode had been manipulated through the coronary sinus and right atrium. A plan of management is proposed for dealing with this unexpected problem. Images PMID:601745

61 year old female presented with chief complaints of headache for 30 days, fever for 10 days, altered behavior for 10 days and convulsion for 2 days. She was diagnosed and treated as a case of carcinoma of left breast 5 years ago. MRI brain showed a lobulated lesion in the left frontal lobe. She came to our hospital for whole brain radiation as a diagnosed case of carcinoma of breast with brain metastasis. Review of MRI brain scan, revealed metastasis or query infective pathology. MR spectroscopy of the lesion revealed choline: creatinine and choline: NAA (N-Acetylaspartate) ratios of ∼1.6 and 1.5 respectively with the presence of lactate within the lesion suggestive of infective pathology. She underwent left fronto temporal craniotomy and evacuation of abscess and subdural empyema. Gram stain showed gram positive cocci. After 1 month of evacuation and treatment she was fine. This case suggested a note of caution in every case of a rapidly evolving space-occupying lesion independent of the patient's previous history. Copyright © 2015 The Authors.

Congestive Heart Failure (CHF) is a cardiovascular disease that affects about 5.7 million people in the US. The most prevalent comorbidity to CHF is Atrial Fibrillation (AF). These two pathologies present in a mutually worsening manner in that patients diagnosed with CHF are more likely to develop AF and patients who are diagnosed with AF are more likely to develop CHF. The underlying pathophysiological mechanisms have been studied for several years and the most recent efforts are in the cellular and molecular basis. In this paper, we focus on manifestation of CHF and AF symptoms as influenced by the posture assumed by a patient. We consider three postures - Left lateral decubitus, right lateral decubitus and supine. We review the clinical evidence gathered thus far relating enhanced sympathetic activity to the left lateral decubitus and supine positions with equivalent evidence on the enhanced vagal activity when the right lateral decubitus posture is assumed. We conclude with a compilation of all the hypotheses on the mechanism by which the right lateral decubitus posture alleviates the symptoms of CHF and AF, and future avenues for investigation.

Impaired Development of Left Anterior Heart Field by Ectopic Retinoic Acid Causes Transposition of the Great Arteries

2015-01-01

Background Transposition of the great arteries is one of the most commonly diagnosed conotruncal heart defects at birth, but its etiology is largely unknown. The anterior heart field (AHF) that resides in the anterior pharyngeal arches contributes to conotruncal development, during which heart progenitors that originated from the left and right AHF migrate to form distinct conotruncal regions. The aim of this study is to identify abnormal AHF development that causes the morphology of transposition of the great arteries. Methods and Results We placed a retinoic acid–soaked bead on the left or the right or on both sides of the AHF of stage 12 to 14 chick embryos and examined the conotruncal heart defect at stage 34. Transposition of the great arteries was diagnosed at high incidence in embryos for which a retinoic acid–soaked bead had been placed in the left AHF at stage 12. Fluorescent dye tracing showed that AHF exposed to retinoic acid failed to contribute to conotruncus development. FGF8 and Isl1 expression were downregulated in retinoic acid–exposed AHF, and differentiation and expansion of cardiomyocytes were suppressed in cultured AHF in medium supplemented with retinoic acid. Conclusions The left AHF at the early looped heart stage, corresponding to Carnegie stages 10 to 11 (28 to 29 days after fertilization) in human embryos, is the region of the impediment that causes the morphology of transposition of the great arteries.

Left ventricular wall rupture remains a major lethal complication of acute myocardial infarction and hypertension is a well-known predisposing factor of cardiac rupture after myocardial infarction. An 87-year-old man was admitted to our hospital, diagnosed as acute myocardial infarction (AMI). The echocardiogram showed 0.67-cm(2) aortic valve, consistent with severe aortic stenosis (AS). A coronary angiography showed a chronic occlusion of the proximal left circumflex artery and a 99 % stenosis and thrombus in the mid right coronary artery. During percutaneous angioplasty of the latter, transient hypotension and bradycardia developed at the time of balloon inflation, and low doses of noradrenaline and etilefrine were intravenously administered as needed. The patient suddenly lost consciousness and developed electro-mechanical dissociation. Cardio-pulmonary resuscitation followed by insertion of an intra-aortic balloon pump (IABP) and percutaneous cardiopulmonary support were initiated. The echocardiogram revealed moderate pericardial effusion, though the site of free wall rupture was not distinctly visible. A left ventriculogram clearly showed an infero-posterior apical wall rupture. Surgical treatment was withheld because of the interim development of brain death. In this patient, who presented with severe AS, the administration of catecholamine to stabilize the blood pressure probably increased the intraventricular pressures considerably despite apparently normal measurements of the central aortic pressure. IABP, temporary pacemaker, or both are recommended instead of intravenous catecholamines for patients with AMI complicated with significant AS to stabilize hemodynamic function during angioplasty.

Persistent ICT Malaria P.f/P.v Panmalarial and HRP2 Antigen Reactivity after Treatment of Plasmodium falciparum Malaria Is Associated with Gametocytemia and Results in False-Positive Diagnoses of Plasmodium vivax in Convalescence

A problem with rapid Plasmodium falciparum-specific antigen histidine-rich protein 2 (HRP2) detection tests for malaria is the persistence of antigen in blood after the disappearance of asexual-stage parasitemia and clinical symptoms, resulting in false-positive (FP) test results following treatment. The ICT P.f/P.v immunochromatographic test detects both HRP2 and a panmalarial antigen (PMA) found in both P. falciparum and Plasmodium vivax. To examine posttreatment antigen persistence with this test and whether persistent sexual-stage forms (gametocytes) are a cause of FP tests after treatment, we compared serial antigen test results with microscopy results from patients symptomatic with P. falciparum malaria in Indonesia for 28 days following treatment with chloroquine (CQ; n = 66), sulfadoxine-pyrimethamine (SP; n = 36), and artesunate plus sulfadoxine-pyrimethamine (ART + SP; n = 15). Persistent FP antigenemia following SP treatment occurred in 29% (HRP2) and 42% (PMA) of the patients on day 7 and in 10% (HRP2) and 23% (PMA) on day 14. The high rates of persistent HRP2 and PMA antigenemia following CQ and SP treatment were strongly associated with the presence of gametocytemia, with the proportion with gametocytes on day 7 posttreatment being significantly greater in those with FP results than in those with true-negative PMA and HRP2 results. Gametocyte frequency on day 14 post-SP treatment was also greater in those with FP PMA results. Following SP treatment, PMA persisted longer than HRP2, giving an FP diagnosis of P. vivax in up to 16% of patients on day 14, with all FP P. vivax diagnoses having gametocytemia. In contrast, PMA was rapidly cleared following ART + SP treatment in association with rapid clearance of gametocytemia. Gametocytes appear to be an important cause of persistent posttreatment panmalarial antigenemia in areas of endemicity and may also contribute in part to persistent HRP2 antigenemia following treatment.

A 28-year-old right-handed man noticed weakness in his legs, three days after an ephedrine overdose. Initial brain magnetic resonance imaging showed lesions in the parietal regions bilaterally. Computed tomography angiography showed segmental and multifocal vasoconstriction of the cerebral arteries. After treatment, clinical and radiological findings resolved, suggesting the patient had reversible cerebral vasoconstriction syndrome with posterior reversible encephalopathy syndrome. However, he had residual agraphia of the left hand. Language testing revealed no difficulties in oral expression, auditory comprehension, understanding of written language, or writing with the right hand. I-123 iodoamphetamine single-photon emission computed tomography showed residual dysfunction in the left superior parietal lobule. There were no apparent signs of other disconnection syndromes or neuroimaging abnormalities in the corpus callosum. We diagnosed left-hand agraphia due to left parietal dysfunction. Our case suggests that left superior parietal dysfunction without callosal lesions is a possible cause of left-hand agraphia. Neural mechanisms for writing with the right or left hand may be separable at the cortical level.

Objective: Infantile digital fibromatosis is a rare benign childhood tumor, infrequently cited in the literature. Hallmarks include nodular growths exclusive to fingers and toes and the presence of eosinophilic cytoplasmic inclusions on histology. This article aims to exemplify diagnoses of infantile digital fibromatosis and possible treatment options. Methods: A computerized English literature search was performed in the PubMed/MEDLINE database using MeSH headings "infantile," "juvenile," "digital," and "fibromatosis." Twenty electronic publications were selected and their clinical and histological data recorded and used to compile a treatment algorithm. Results: A 9-month-old male child was referred for a persistent, symptomatic nodule on the third left toe. A direct excision with Brunner-type incisions was performed under general anesthesia. The procedure was successful without complications. The patient has no recurrence at 2 years postsurgery and continues to be followed. Histological examination revealed a proliferation of bland, uniformly plump spindle cells with elongated nuclei and small central nucleoli without paranuclear inclusions consistent with fibromatosis. Conclusions: Asymptomatic nodules should be observed for spontaneous regression or treated with nonsurgical techniques such as chemotherapeutic or steroid injection. Surgical removal should be reserved for cases with structural or functional compromise.

Iodine-induced hyperthyroidism as combination of different etiologies: an overlooked entity in the elderly.

Iodine-induced thyrotoxicosis, which raises several diagnostic and therapeutical challenges, is often overlooked. Hyperthyroidism can induce atrial fibrillation, a harmful arrhythmia which can precipitate heart failure and cause stroke. We report the case of an elderly man who was diagnosed with tachyfibrillation secondary to hyperthyroidism. Thyroid hyperfunction was subsequently related both to previous amiodarone therapy (probably mixed form) and the recent use of iodinated contrast medium for computed tomography scan. Thyroid ultrasonography showed a plongeant multinodular goitre. After initial worsening, thyroid function improved slowly but progressively on high-dose thyreostatic therapy combined with steroid therapy; tachyfibrillation caused heart failure and a thrombus in the left atrium, and proved initially resistant to combined antiarrhythmic treatments. Progressive reduction in thyroid hormone levels, together with combined cardiologic therapies, controlled the heart rate, though atrial fibrillation persisted; anticoagulant therapy resolved the atrial thrombus. Alterations in thyroid function are common in amiodarone-treated patients, who therefore require regular hormonal checks. The different forms of amiodarone-induced thyrotoxicosis must be investigated, since they require different therapies, though mixed forms often occur. The superimposition of further iodine excess due to other causes may be catastrophic and cause severe cardiac problems in these patients.

Myiasis is caused by the larval stages of flies feeding on live or dead mammalian tissues and fluids. Human cases involving the genitourinary system are very rare and present with unusual symptoms.We report the case of a male, 25-year-old shepherd who underwent a surgical intervention on his urinary tract for renal lithiasis and was catheterized with a drain dwelling in his left kidney. A few days after the patient showed signs of dysuria, polyuria and pollakisuria. Lower urinary tract infection with ciprofloxacin susceptible E. coli was diagnosed and treated accordingly. The symptoms persisted and, a few days later, fly maggots were released repeatedly in the urine of the patient and sent for investigation. Macroscopic analysis and microscopy were performed. We detected 3-4 mm long, dorso-ventrally flattened white live fly larvae with lateral projections, typical for Fannia (Diptera: Fannidae) genus. Identification on a species level could not be performed as larva feeding facilities or specific DNA based methods were not available for us.Even if maggot urinary tract infestations are extremely rare in Europe, we should consider them in order to provide a rapid and correct diagnosis followed by an adequate treatment.

Pheochromocytomas in pregnancy are rare but potentially lethal. Even rarer is the combination of pheochromocytoma in pregnancy with subsequent development of ectopic Cushing's syndrome. We report a 36-year-old woman, previously diagnosed with essential hypertension, who developed severe hypertension in pregnancy complicated by insulin-dependent gestational diabetes. A cesarean section was performed at 32 weeks following a hypertensive crisis after routine administration of betamethasone. Postnatal persistence of signs and symptoms of catecholamine excess led to the diagnosis of a left adrenal pheochromocytoma. Between diagnosis and planned tumor removal, the patient developed signs and symptoms of Cushing's syndrome (facial edema and hirsutism, myopathy and fatigue). Biochemical testing confirmed hypercortisolism with extremely elevated levels of plasma adrenocorticotropin, urinary cortisol and multiple steroids of a plasma panel that were all normal at previous testing. The previously noradrenergic tumor also started producing epinephrine. Histopathological examination confirmed the pheochromocytoma, which was also immunohistochemically positive for adrenocorticotropin. Full post-surgical recovery was sustained with normal blood pressure and biochemical findings after one year. This report not only underlines the chameleon behavior of pheochromocytoma but also illustrates its potential for a metamorphosing presentation. Corticosteroid administration in pregnancy requires a cautious approach in patients with hypertension.

Mental nerve paresthesia secondary to initiation of endodontic therapy: a case report

2014-01-01

Whenever endodontic therapy is performed on mandibular posterior teeth, damage to the inferior alveolar nerve or any of its branches is possible. Acute periapical infection in mandibular posterior teeth may also sometimes disturb the normal functioning of the inferior alveolar nerve. The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or mental nerve paresthesia. Paresthesia usually manifests as burning, prickling, tingling, numbness, itching or any deviation from normal sensation. Altered sensation and pain in the involved areas may interfere with speaking, eating, drinking, shaving, tooth brushing and other events of social interaction which will have a disturbing impact on the patient. Paresthesia can be short term, long term or even permanent. The duration of the paresthesia depends upon the extent of the nerve damage or persistence of the etiology. Permanent paresthesia is the result of nerve trunk laceration or actual total nerve damage. Paresthesia must be treated as soon as diagnosed to have better treatment outcomes. The present paper describes a case of mental nerve paresthesia arising after the start of the endodontic therapy in left mandibular first molar which was managed successfully by conservative treatment.

2014-01-01

Gestational trophoblastic neoplasia (GTN) is a disease of women in reproductive age. It is one of the most chemotherapy responsive and highly curable cancer. It is diagnosed when there is clinical, radiologic, pathologic, and/or hormonal evidence of persistent or relapsed gestational trophoblastic disease. In most instances, it is cured by surgical evacuation of the uterus. If persistent, it is treated with chemotherapy which provides response in >90% of the cases. In the unresponsive persistent cases and if the women has completed her child bearing, hysterectomy is generally recommended. Here, we report a rare case of chemoresistant GTN which was confirmed to be placental-site trophoblastic tumour (PSTT) on biopsy. PMID:25177610

A case of left inferior vena cava.

2001-12-01

A case of left inferior vena cava (IVC) was found in a 72-year-old male cadaver during student dissection practice in 1999 at Gifu University School of Medicine. It was formed by junction of the left and right common iliac veins at the lower left corner of the 5th lumbar vertebra. This IVC (15-mm caliber) ascended 82 mm along the left side of the abdominal aorta dorsally to the ureter. Receiving the left renal vein, it became 21 mm in caliber and ran obliquely upward for 43 mm across the abdominal aorta. As soon as it received two right renal veins at the level of the 2nd lumbar vertebra, the IVC (25-mm caliber) turned directly above. The present case belongs to Type C of the classification of McClure and Butler (1925), which is based on the combinations of the left and right IVCs, and on their location relative to the ureters. The present case also belongs to Type 1 of the classification of Yoshida et al. (1981). We consider that left IVC in the present case is mainly caused by disappearance of the right supracardinal vein and persistence of the left one during the embryological development of the IVC.

Cervical intraepithelial neoplasia grade 2 (CIN2) frequently regresses, is typically slow-growing, and rarely progresses to cancer. Some women forgo immediate treatment, opting for conservative management (heightened surveillance with cytology and colposcopy), to minimize overtreatment and increased risk of obstetric complications; however, there are limited data examining clinical outcomes in these women. We performed a retrospective cohort analysis of younger women diagnosed with initially untreated CIN1/2, CIN2 and CIN2/3 lesions at Kaiser Permanente Northern California between 2003 and 2015. Clinical outcomes were categorized into five mutually exclusive hierarchical groups: cancer, treated, returned to routine screening, persistent high-grade lesion, or persistent low-grade lesion. Median follow-up for the 2,417 women was 48 months. Six women were diagnosed with cancer (0.2%), all with history of high-grade cytology, and none after a negative cotest. Thirty percent of women were treated, and only 20% returned to routine screening; 50% remained in continued intensive follow-up, of which 86% had either low-grade cytology/histology or high-risk human papillomavirus (HPV) positivity, but not necessarily persistence of a single HPV type. No cancers were detected after a single negative cotest in follow-up. Almost half of initially untreated women did not undergo treatment, but remained by protocol in colposcopy clinic for 2 or more years in the absence of persisting CIN2 + Their incomplete return to total negativity was possibly due to sequential new and unrelated low-grade abnormalities. The prolonged colposcopic surveillance currently required to return to routine screening in the absence of persisting CIN2 + might not be necessary after a negative cotest. Significance: Many younger women under conservative management following an initial CIN2 result remain in a clinical protocol of prolonged intensified surveillance without a subsequent diagnosis of CIN2 or more severe diagnoses. More research is needed to determine whether such prolonged management might be unnecessary following a negative cotest for those women with an initial CIN2 but otherwise only low-grade findings.

2011-01-01

Background and Objectives: We present a case of Laparoendoscopic Single Site Surgery (LESS) left adrenalectomy performed with a conventional laparoscope and instruments. Methods: A 45-year-old male was diagnosed with hyperaldosteronism. Computed tomography detected a left adrenal nodule. Bilateral adrenal vein sampling was consistent with a left-sided source for hyperaldosteronism. Results: Total operative time for LESS left adrenalectomy was 120 minutes. The surgery was performed with conventional instruments, a standard 5-mm laparoscope, and a SILS port, with no additional incisions or trocars needed. No complications occurred, and the patient reported an uneventful recovery. Conclusions: LESS adrenalectomy is a feasible procedure. Although articulating instruments and laparoscopes may offer advantages, LESS adrenalectomy can be done without these. PMID:21902983

Periocular necrotizing fasciitis in an infant.

PubMed

Proia, Alan D

Periocular necrotizing fasciitis developed in a 12-month-old boy with swelling of both eyes and redness and a discharge from the left eye approximately 36 hours after blunt trauma. Computed tomography revealed preseptal and soft-tissue edema on the left side, but no signs of orbital involvement, orbital fractures, or drainable abscess in the anterior left lower eyelid. The inflammatory signs worsened over the next day, and there was purulent discharge from the left lower eyelid and an abscess and necrosis of the lower eyelid skin. He did well following surgical debridement and treatment with intravenous antibiotics. His course highlights the difficulty in diagnosing necrotizing fasciitis and the necessity for prompt surgical debridement and empirical broad-spectrum antibiotic therapy.

2014-01-01

A 41-year-old woman with a history of asthma arrived at the emergency room of our hospital with dyspnea. The electrocardiogram showed no specific results. Echocardiography defects revealed an obvious decrease in the left ventricular systolic function and enlargement of the left chamber. We initially considered her condition to be dilated cardiomyopathy. However, she had eosinophilia in the peripheral blood and elevated cardiac enzymes. The coronary angiography showed normal coronary arteries. Single photon emission computed tomography (SPECT) showed infiltrative myocardial disease. She was then diagnosed with eosinophil infiltrations. Combined with peripheral nerve injury and lung involvement, she was diagnosed as having Churg-Strauss syndrome. After initiating prednisone treatment, her eosinophilia and rising cardiac enzymes recovered to normal, and both her echocardiographic abnormalities and symptoms noticeably improved.

2015-01-01

We present the case of a boy born with a large macular, segmental vascular anomaly over the left face, initially diagnosed as a capillary malformation (port-wine stain) by the postnatal paediatric team. The vascular anomaly in the face then grew rapidly during the first few weeks of life and started to occlude the left eye, causing parental concerns about the infant's vision. A dermatological opinion established that the lesion was a segmental infantile haemangioma (IH). This, in combination with the posterior fossa malformation previously detected on antenatal scanning and confirmed by an MRI postnatally, satisfied the criteria for Posterior fossa abnormalities, Haemangiomas, Arterial abnormalities, Cardiac abnormalities and Eye abnormalities (PHACE) syndrome: a rare cutaneous neurovascular syndrome. This case highlights the diagnostic challenge posed by early phenotypes of haemangiomas as well as the importance of correctly diagnosing PHACE syndrome. PMID:26177999

A 62 year-old male with long-standing smoking history presented with hemoptysis. Plain chest x-ray showed abnormal findings proximate to the right pulmonary hilum. Bronchoscopy revealed a fragile exophytic tumor of the right wall of the lower third of the trachea, infiltrating the right main bronchus (75% stenosis) and the right upper lobar bronchus (near total occlusion). Contrast-enhanced chest CT demonstrated a 7.2x4.9 cm tumor contiguous to the above-mentioned structures, mediastinal lymph node pathology, and a vessel coursing inferiorly to the left of the aortic arch and anterior to the left hilum. Despite the tumor constricting the right superior vena cava, no signs of superior vena cava syndrome were present. In this case, the patient does not present with Superior Vena Cava (SVC) syndrome, as expected due to the constriction of the (right) SVC caused by the tumor, since head and neck veins drain through the Persistent Left Superior Vena Cava (PLSVC). PLSVC is the most common thoracic venous anomaly with an incidence of 0.3% to 0.5% of the general population and it is a congenital anomaly caused by the failure of the left anterior cardinal vein to regress and to consequently form the ligament of Marshall during fetal development. It is associated with absence of the left brachiocephalic vein and in 10 to 20% of cases the right SVC is absent. Two potential draining points of the PLSVC have been previously reported. In the majority of cases PLSVC drains directly into the coronary sinus, but less frequently it drains into the left atrium or the left superior pulmonary vein. In cases where the PLSVC drains into the coronary sinus, congenital heart defects are rare. The patient usually remains asymptomatic and PLSVC is an incidental finding during radiographic imaging or medical procedures. When the PLSVC drains into the left atrium or the left superior pulmonary vein, a right-to-left shunt is formed; a condition usually asymptomatic. In some reported cases this PLSVC variant presents with persistent, unexplained hypoxia or cyanosis and embolisation causing recurrent transient ischemic attacks and/or cerebral abscesses. This PLSVC variant is more often associated with absence of the right SVC and congenital heart abnormalities.

The aim of our study was to investigate, whether enhancement of left atrial cryoablation by ablation of the autonomic nervous system of left atrium leads to influencing the outcomes of surgical treatment of atrial fibrillation in patients with structural heart disease undergoing open-heart surgery. The observed patient file consisted of 100 patients, who have undergone a combined open-heart surgery at our department between July 2012 and December 2014. The patients were indicated for the surgical procedure due to structural heart disease, and suffered from paroxysmal, persistent, or long-standing persistent atrial fibrillation. In all cases, left atrial cryoablation was performed in the extent of isolation of pulmonary veins, box lesion, connecting lesion with mitral annulus, amputation of the left atrial appendage and connecting lesion of the appendage base with left pulmonary veins. Furthermore, 35 of the patients underwent mapping and radiofrequency ablation of ganglionated plexi, together with discision and ablation of the ligament of Marshall (Group GP). A control group was consisted of 65 patients without ganglionated plexi intervention (Group LA). The main primary outcome was establishment and duration of sinus rhythm in the course of one-year follow-up. Evaluation of the number of patients with a normal sinus rhythm in per cent has shown comparable values in both groups (Group GP - 93.75%, Group LA - 86.67%, p = 0.485); comparable results were also observed in patients with normal sinus rhythm without anti-arrhythmic treatment in the 12th month (Group GP - 50%, Group LA - 47%, p = 0.306). We have not observed any relation between the recurrence of atrial fibrillation and the presence of a mitral valve surgery, or between the presence of a mitral and tricuspid valves surgery and between the left atrial diameter > 50 mm. Enhancement of left atrial cryoablation by gangionated plexi ablation did not influence the outcomes of surgical ablation due to atrial fibrillation in our population in the course of 12-month follow-up. The study was approved retrospectively by the Ethics Committee of the University Hospital Ostrava ( reference number 867/2016).

Anomalies of the systemic venous return: a review.

1990-06-01

Congenital anomalies of the systemic venous connection to the heart represent a rather wide and heterogeneous group of malformations, whose physiological consequences may vary from nil to the most severe form of systemic arterial desaturation. The malformations may be summarized as follows: (1) Left superior vena cava connected to the coronary sinus, interrupted inferior vena cava and absent right superior vena cava that do not indicate surgical repair 'per se', but require some technical attention during open heart surgery performed for other anomalies; (2) Left superior vena cava connected to the left atrium, due to incorporation of the coronary sinus into the left atrial cavity, resulting in a right-to-left-shunt; (3) Right superior vena cava or inferior vena cava draining into the left atrium, both are extremely rare and require treatment for the ensuing right-to-left shunt; (4) Total anomalous systemic venous connection to the left atrium, usually combined with atrial isomerism and other very complex heart malformations; (5) Cor triatriatum dexter, which has been frequently diagnosed as an anomalous venous connection for its similar hemodynamic consequences. Such anomalies are reviewed with particular respect to their surgical implications.

White matter developmental trajectories associated with persistence and recovery of childhood stuttering.

Stuttering affects the fundamental human ability of fluent speech production, and can have a significant negative impact on an individual's psychosocial development. While the disorder affects about 5% of all preschool children, approximately 80% of them recover naturally within a few years of stuttering onset. The pathophysiology and neuroanatomical development trajectories associated with persistence and recovery of stuttering are still largely unknown. Here, the first mixed longitudinal diffusion tensor imaging (DTI) study of childhood stuttering has been reported. A total of 195 high quality DTI scans from 35 children who stutter (CWS) and 43 controls between 3 and 12 years of age were acquired, with an average of three scans per child, each collected approximately a year apart. Fractional anisotropy (FA), a measure reflecting white matter structural coherence, was analyzed voxel-wise to examine group and age-related differences using a linear mixed-effects (LME) model. Results showed that CWS exhibited decreased FA relative to controls in the left arcuate fasciculus, underlying the inferior parietal and posterior temporal areas, and the mid body of corpus callosum. Further, white matter developmental trajectories reflecting growth rate of these tract regions differentiated children with persistent stuttering from those who recovered from stuttering. Specifically, a reduction in FA growth rate (i.e., slower FA growth with age) in persistent children relative to fluent controls in the left arcuate fasciculus and corpus callosum was found, which was not evident in recovered children. These findings provide first glimpses into the possible neural mechanisms of onset, persistence, and recovery of childhood stuttering.

Objective To examine the outcome of women diagnosed with vulvar intraepithelial neoplasia (VIN) 3 at less than 35 years. Materials and Methods All cases of VIN 3 treated in women less than 35 years treated at Roswell Park Cancer Institute between January 1973 and January 2008 were reviewed. Medical records were reviewed for year of diagnosis, treatment modality, recurrence and/or progression, associated medical conditions, history of genital condyloma, smoking status, history of cervical pathology, and treatment. Results Thirty-one women were identified. The mean age at diagnosis was 29 years. Smoking status was available in 28 patients, of which 82% (23/28) were current or former smokers. Eighty-one percent (25/31) of the women had cervical disease. Fifty-two percent (16/31) had a history of genital condyloma. Ten of the 31 women (32%) were diagnosed with persistence or recurrence of VIN 3. Three women (9.7%) progressed to invasive carcinoma. Conclusions Women diagnosed with VIN 3 at less than 35 years are at risk for persistence and/or recurrence of their disease as well as progression to carcinoma, warranting frequent and prolonged follow-up with liberal utilization of directed biopsies of suspicious lesions.

The purpose of this study was to determine the epidemiological and clinical characteristics of patients diagnosed with tularemia and the effectiveness of the administered treatments. Patients treated in our hospital between January 2009 and March 2011 and diagnosed with tularemia were evaluated retrospectively. Patients' epidemiological and clinical characteristics, administered treatments, and posttreatment findings were recorded on patient monitoring forms. At anamnesis, 29% of patients used water from wells and 71% used water from the network supply; moreover, 48.4% had a history of contact with animals and 87.1% a history of lethargy. At physical examination, 96.8% had a mass in the neck and 90.3% had fever. Gentamycin + doxycycline therapy was administered to 45.2% of patients, while levofloxacin, gentamycin, and streptomycin were used for the other patients. After treatment, neck masses persisted in 48.4% of patients and complaints of lethargy and fever in 6.5%. Treatment of these patients was initiated once tularemia had been diagnosed, as test results were announced about 3 weeks later. Lymphadenopathy excision was performed on 19.4% of patients in whom neck mass persisted. Appropriate empiric antibiotherapy should be commenced in patients presenting with neck mass, fever, and lethargy in regions with tularemia epidemics.

A developmental improvement of symptoms in attention-deficit/hyperactivity disorder (ADHD) is frequently reported, but the underlying neurobiological substrate has not been identified. The aim of this study was to determine whether white matter microstructure is related to developmental improvement of ADHD symptoms. A cross-sectional magnetic resonance imaging (MRI) analysis was embedded in a prospective follow-up of an adolescent cohort of ADHD and control subjects (NeuroIMAGE). Mean age at baseline was 11.9 years, mean interval of follow-up was 5.9 years. About 75.3% of the original cohort was retained successfully. Data of 101 participants with ADHD combined type at baseline and 40 healthy controls were analysed. ADHD symptoms were measured with semistructured, investigator-based interviews and Conners' questionnaires, on the basis of DSM-IV criteria. Fractional anisotropy (FA) and mean diffusivity (MD) indices of white matter microstructure were measured using whole brain diffusion tensor imaging at follow-up only. In a dimensional analysis FA and MD were related to change in ADHD symptoms. To link this analysis to DSM-IV diagnoses, a post hoc categorical group analysis was conducted comparing participants with persistent (n = 59) versus remittent (n = 42) ADHD and controls. Over time, participants with ADHD showed improvement mainly in hyperactive/impulsive symptoms. This improvement was associated with lower FA and higher MD values in the left corticospinal tract at follow-up. Findings of the dimensional and the categorical analysis strongly converged. Changes in inattentive symptoms over time were minimal and not related to white matter microstructure. The corticospinal tract is important in the control of voluntary movements, suggesting the importance of the motor system in the persistence of hyperactive/impulsive symptoms. © 2015 Association for Child and Adolescent Mental Health.

N-terminal pro-brain natriuretic peptide (NT-proBNP) release is associated with left ventricular expansion and pressure overload. Elevation of serum levels of natriuretic peptides is observed in patients with impaired as well as preserved left ventricular systolic function. High NT-proBNP has been shown to be related not only to preload but also to increased afterload, especially blood pressure and arterial stiffness. The aim of the study was to evaluate the association of NT-proBNP and echocardiographic parameters in hypertensives with metabolic syndrome. The study group comprised 133 patients (99 men; mean age 45.9 ± 9.4 years) with at least a 3-month history of arterial hypertension (stages 1 and 2) and fulfilling the diagnostic criteria for metabolic syndrome. Following initial clinical assessment, which included NT-proBNP levels, they underwent two-dimensional echocardiography. Echocardiographic abnormalities were observed in 60 subjects (45.1%), including left ventricular diastolic dysfunction (LVDdf) in 41 (30.8%) and left ventricular hypertrophy (LVH) in 35 (26.3%). Higher NT-proBNP concentrations were observed in patients with LVH, especially in the presence of LVDdf. Further analysis demonstrated that NT-proBNP correlated negatively with septal E' (r = -0.38; p = 0.015) and heart rate (r = -0.42; p = 0.006) in patients with LVDdf, and positively with left ventricular end diastolic diameter (r = 0.46; p = 0.006) and left ventricular mass index (r = 0.49; p = 0.005) in subjects with LVH. However, the analysis of ROC curves revealed no NT-proBNP level of good sensitivity and specificity in diagnosing LVDdf/LVH (maximal area under the curve 0.571). Even a relatively low NT-proBNP concentration can be a useful marker of left ventricular hypertrophy and end-diastolic wall stretch. However, in the present study there was no NT-proBNP level of satisfactory predictive value to diagnose LV abnormalities.

Association between the presence of left atrial low-voltage areas and atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI) has been shown mainly in persistent AF patients. We sought to compare the AF recurrence rate in paroxysmal AF patients with and without left atrial low-voltage areas. This prospective observational study included 147 consecutive patients undergoing initial ablation for paroxysmal AF. Voltage mapping was performed after PVI during sinus rhythm, and low-voltage areas were defined as regions where bipolar peak-to-peak voltage was <0.50mV. Left atrial low-voltage areas after PVI were observed in 22 (15%) patients. Patients with low-voltage areas were significantly older (72±6 vs. 66±10, p<0.0001), more likely to be female (68% vs. 32%, p=0.002), and had higher CHA 2 DS 2 -VASc score (2.5±1.5 vs. 1.8±1.3, p=0.028). During a mean follow-up of 22 (18, 26) months, AF recurrence was observed in 24 (16%) and 16 (11%) patients after the single and multiple ablation procedures, respectively. AF recurrence rate after multiple ablations was higher in patients with low-voltage areas than without (36% vs. 6%, p<0.001). Low-voltage areas were independently associated with AF recurrence even after adjustment for the other related factors (Hazard ratio, 5.89; 95% confidence interval, 2.16 to 16.0, p=0.001). The presence of left atrial low-voltage areas after PVI predicts AF recurrence in patients with paroxysmal AF as well as in patients with persistent AF. Copyright © 2017 Elsevier B.V.

The common sites for metastases from breast cancer are lymph nodes, bone, lung, liver, and brain. Gastrointestinal (GI) metastasis is rarely found or diagnosed in patients with breast cancer. This report presents three cases of gastric metastasis from breast cancer. Case 1 was a 42-year-old female diagnosed with gastric metastasis after mastectomy with axillary lymph node dissection for invasive lobular carcinoma of the left breast. Case 2 was a 54-year-old female who was diagnosed to have invasive lobular carcinoma of the left breast with systemic bone and gastric metastasis. Case 3 was a 54-year-old female who was diagnosed to have bilateral invasive ductal carcinoma of the breast with simultaneous bone and gastric metastasis. The immunohistochemical statuses for estrogen receptor, progesterone receptor, mammaglobin, and gross cystic disease fluid protein-15 (GCDFP-15) between the primary and gastric metastatic lesions were all well matched. All three cases were treated with systemic chemotherapy, hormone therapy or both, without surgical intervention for gastric lesions. Two patients with disseminated disease died 27 and 58 months after diagnosis of gastric metastasis, while one patient without organ metastasis is still alive at 56 months after diagnosis. It is important to make a correct diagnosis by distinguishing gastric metastasis from breast cancer in order to select the optimal initial treatment for systemic disease of breast cancer.

The aim of this study was to investigate the presence of persistent reflux flow on the first postoperative day using color Doppler sonography (CDS) in patients who had undergone sub-inguinal varicocelectomy, and to research the relationship between persistent reflux flow and recurrent varicocele. A total of 54 patients were included in the study. Ages of the patients were between 21 and 38 years (mean 27.3 ± 7.6). All patients were evaluated four times with CDS: preoperatively, first postoperative day, 3 months postoperative, and finally 6 months after the operation. Preoperative venous diameters were measured between 3 and 5.5 mm; mean vein diameters were 3.8 ± 0.7 mm for the left side and 3.4 ± 0.4 mm for the right side. Mean duration of reflux was 3.5 ± 0.3 seconds on the left side and 2.9 ± 0.7 seconds on the right side. First postoperative day persistent Valsalva-induced reflux flow was seen in 10 patients (18%). Mean venous diameter was measured 1.8 ± 0.9 mm. Three months after the operation, Valsalva-induced reflux flow was seen in two patients (3%) in whom reflux was not seen on the first postoperative day. After 6 months, venous diameters larger than 2 mm at rest and the occurrence of reflux during the Valsalva maneuver were considered to be a recurrence. Six months after the operation, 12 patients had recurrent varicocele. Detecting persistent reflux with CDS on the first postoperative day was found to be 85% sensitive and 100% specific for showing recurrence. Valsalva-induced persistent reflux flow investigated with CDS on the first postoperative day can be used to show success of the surgery and is also an indicator of recurrence in varicocelectomy patients.

Elevated amygdala activity to sad facial expressions: a state marker of bipolar but not unipolar depression.

Difficulties in emotion processing and poor social function are common to bipolar disorder (BD) and major depressive disorder (MDD) depression, resulting in many BD depressed individuals being misdiagnosed with MDD. The amygdala is a key region implicated in processing emotionally salient stimuli, including emotional facial expressions. It is unclear, however, whether abnormal amygdala activity during positive and negative emotion processing represents a persistent marker of BD regardless of illness phase or a state marker of depression common or specific to BD and MDD depression. Sixty adults were recruited: 15 depressed with BD type 1 (BDd), 15 depressed with recurrent MDD, 15 with BD in remission (BDr), diagnosed with DSM-IV and Structured Clinical Interview for DSM-IV Research Version criteria; and 15 healthy control subjects (HC). Groups were age- and gender ratio-matched; patient groups were matched for age of illness onset and illness duration; depressed groups were matched for depression severity. The BDd were taking more psychotropic medication than other patient groups. All individuals participated in three separate 3T neuroimaging event-related experiments, where they viewed mild and intense emotional and neutral faces of fear, happiness, or sadness from a standardized series. The BDd-relative to HC, BDr, and MDD-showed elevated left amygdala activity to mild and neutral facial expressions in the sad (p < .009) but not other emotion experiments that was not associated with medication. There were no other significant between-group differences in amygdala activity. Abnormally elevated left amygdala activity to mild sad and neutral faces might be a depression-specific marker in BD but not MDD, suggesting different pathophysiologic processes for BD versus MDD depression.

2017-03-01

Each skeletal muscle is usually supplied by two or more nerve roots and if one nerve root is affected and the other is spared, the clinically used F wave minimum latency can still be normal. An F wave index was constructed taking into consideration the other parameters of the F wave such as persistence, chronodispersion, latency, arm-length to determine its usefulness in the diagnosis of peripheral neuropathy. This study was undertaken to construct the F wave index in the upper limb for the median nerve in normal healthy adult males and in patients with peripheral neuropathy and to compare the values obtained in both groups. This hospital-based study was carried out on 40 males who were diagnosed to have peripheral neuropathy and on 40 age matched healthy males who served as the control group. The F wave recording was done using a digitalized nerve conduction/electromyography/EP machine in a quiet and dimly lit room. All recordings were done between 0900 and 1100 h at an ambient temperature of 22°C. The F wave recording was obtained from a fully relaxed muscle by stimulating the median nerve. The median value for F wave index obtained from median nerve (abductor pollicis brevis) in patients with peripheral neuropathy [right arm - 35.85, interquartile range (IQR) - 35.26; left arm - 39.49, IQR - 39.49] was significantly lower (P=0.001) as compared to the control group (right arm - 102.62, IQR - 83.76; left arm - 77.43, IQR - 58.02). Our results showed that F wave index in upper limb was significantly lower in patients with peripheral neuropathy than the healthy controls, and could be used for early detection of peripheral neuropathy.

Pigmented villonodular synovitis (PVNS) is an uncommon entity of proliferative lesion of the synovium, presenting with different clinical signs and symptoms. PVNS rarely forms an osteolytic lesion in a bone. Here we report a unique case of PVNS with a nodular lesion in the left patella. A 37-year-old female was referred to our hospital with complaints of ongoing left knee pain and a painful and palpable mass in her left popliteal fossa. MRI demonstrated a nodular lesion in the left patella, diffuse affected synovial tissue in the left knee and an extra-articular mass in the left popliteal fossa. After a primary diagnosis of PVNS had been established, combined arthroscopic synovectomy and open resection were performed. The postoperative pathological diagnoses of the resected mass from the popliteal fossa, the affected synovial tissue and the lesion in the patella were consistent with PVNS. At 1-year follow-up, no evidence of recurrence was noted. Based on brief literature review of PNVS, we presented a very rare case of PVNS with a nodular lesion in the left patella, diffuse affected synovial tissue in the left knee and an extra-articular mass in the left popliteal fossa.

Purpose Right-sided aortic arch is a rare vessel anomaly with an incidence of 0.1% worldwide. Supra-aortic branches form a mirror image of the left-sided aortic arch or an aberrant left subclavian artery associated with Kommerell diverticulum. Most patients are diagnosed by a difference in blood pressure in each upper extremity or by the presence of left subclavian steal syndrome in their younger age. The diagnosis of onset of ischemic stroke in middle age is rare. Methods We present the case of a female patient who presented with an ischemic stroke in the left posterior circulation area. She had no history of congenital heart malformation. We performed head magnetic resonance imaging, cerebral angiography, and enhanced computed tomography of the aortic arch and major branches. Results The patient had a right-sided aortic arch and an aberrant left subclavian artery. The left subclavian artery was occluded at the proximal portion with a fibrous string. Collateral flow in the anterior cervical subcutaneous area supported left limb perfusion. Conclusion An atheromatous change reduced shunt flow via collateral networks at the anterior cervical region. Congenital subclavian steal supported the ischemic stroke.

We report a case of an infant who was postnatally diagnosed with hypoplastic left heart syndrome and an intact atrial septum who underwent emergent atrial decompression followed by the Norwood operation. She was also found to have a congenital diaphragmatic hernia on the left side and a congenital eventration of the right diaphragm, both requiring surgical repair. She was later found to have an anomalous origin of the left circumflex coronary artery from the right pulmonary artery that was ligated at the time of the bilateral bidirectional Glenn operation. She is currently thriving at home, defying all odds. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

We report a case of lung abscess misdiagnosed as adenocarcinoma based on cytologic findings of the sample obtained from needle biopsy. A 45-year-old man consulted our hospital because of fever, wet cough and an abnormal shadow on a chest X-ray film. A chest computed tomography revealed gradually enlarging pulmonary mass in the left S6 infiltrating the S5. A diagnosis of lung cancer was suspected and surgery was performed. Pathological findings of the specimen showed atypical cells with a large nucleus and a gross papillary neoplasm by needle biopsy. The patient underwent left lower lobectomy and partial resection of upper lobe with standard nodal dissection. The final diagnosis was a lung abscess with pneumonia without evidence of malignancy. When an indeterminate pulmonary tumor must be diagnosed during an operation, we should perform partial resection if possible.

We present the case of a boy born with a large macular, segmental vascular anomaly over the left face, initially diagnosed as a capillary malformation (port-wine stain) by the postnatal paediatric team. The vascular anomaly in the face then grew rapidly during the first few weeks of life and started to occlude the left eye, causing parental concerns about the infant's vision. A dermatological opinion established that the lesion was a segmental infantile haemangioma (IH). This, in combination with the posterior fossa malformation previously detected on antenatal scanning and confirmed by an MRI postnatally, satisfied the criteria for Posterior fossa abnormalities, Haemangiomas, Arterial abnormalities, Cardiac abnormalities and Eye abnormalities (PHACE) syndrome: a rare cutaneous neurovascular syndrome. This case highlights the diagnostic challenge posed by early phenotypes of haemangiomas as well as the importance of correctly diagnosing PHACE syndrome. 2015 BMJ Publishing Group Ltd.

To study the efficacy and safety of radiofrequency catheter ablation (RFCA) in patients with different forms of atrial fibrillation. By retrospective analysis, we summarize 720 cases, where patients diagnosed with atrial fibrillation in our hospital were treated with RFCA from February 2010 to October 2014. Among the cases, 425 were diagnosed with paroxysmal atrial fibrillation and 295 with non-paroxysmal atrial fibrillation (including persistent atrial fibrillation and permanent atrial fibrillation). All patients were followed up until June 2015 to compare and analyze the differences in operation success rates, complications and recurrence rates. 395 cases (92.9%) of paroxysmal atrial fibrillation and 253 cases (85.8%) with non-paroxysmal atrial fibrillation were subject to surgery and followed up. The age of onset, disease course, underlying diseases, left atrial diameter and combined anti-arrhythmics of patients with paroxysmal atrial fibrillation were lower than those of patients with non-paroxysmal atrial fibrillation, and the differences were statistically significant (p < 0.05). The success rate of the first ablation was higher than that of non-paroxysmal atrial fibrillation. Procedure time, procedure method, complications and recurrence rate of patients with paroxysmal atrial fibrillation were lower than those of non-paroxysmal atrial fibrillation group, and the differences were statistically significant (p < 0.05). When we compared apoplexy and heart failure caused by atrial fibrillation in the two groups, the difference was not statistically significant (Apoplexy: p = 0.186; Heart failure: p = 0.170). The individual ablation success rate was higher for paroxysmal atrial fibrillation, and long-term follow-up showed that the occurrence of apoplexy and heart failure was not different from the non-paroxysmal atrial fibrillation group.

Tactile extinction is frequent, debilitating, and often persistent after brain damage. Currently, there is no treatment available for this disorder. In two previous case studies we showed an influence of galvanic vestibular stimulation (GVS) on tactile extinction. Here, we evaluated in further patients the immediate and lasting effects of GVS on tactile extinction. GVS is known to induce polarity-specific changes in cerebral excitability in the vestibular cortices and adjacent cortical areas. Tactile extinction was examined with the Quality Extinction Test (QET) where subjects have to discriminate six different tactile fabrics in bilateral, double simultaneous stimulations on their dorsum of hands with identical or different tactile fabrics. Twelve patients with stable left-sided tactile extinction after unilateral right-hemisphere lesions were divided into two groups. The GVS group (N = 6) performed the QET under six different experimental conditions (two Baselines, Sham-GVS, left-cathodal/right-anodal GVS, right-cathodal/left-anodal GVS, and a Follow-up test). The second group of patients with left-sided extinction (N = 6) performed the QET six times repetitively, but without receiving GVS (control group). Both right-cathodal/left-anodal as well as left-cathodal/right-anodal GVS (mean: 0.7 mA) improved tactile identification of identical and different stimuli in the experimental group. These results show a generic effect of GVS on tactile extinction, but not in a polarity-specific way. These observed effects persisted at follow-up. Sham-GVS had no significant effect on extinction. In the control group, no significant improvements were seen in the QET after the six measurements of the QET, thus ruling out test repetition effects. In conclusion, GVS improved bodily awareness permanently for the contralesional body side in patients with tactile extinction and thus offers a novel treatment option for these patients.

A 46-year-old man was admitted to our clinic because of acute heart failure. Six years before admission he was pointed out cardiomegary and hematuria. One year later, he was diagnosed as having jugular foramen syndrome. On admission, he had a fever and dyspnea. Pansystolic blowing murmur was audible at the apex. The chest ratio on his chest X-ray was 52.5%. An electrocardiogram showed left ventricular hypertrophy. An echocardiogram showed marked dilatation and severe dysfunction of left ventricle. Radionuclide scanning with technetium 99 m pyrophosphate identified inflammatory change in the apex. Myocardial biopsy showed fibrotic degeneration and IgG deposits in myocardium. Blood examination showed anemia, lymphopenia. positive anti-nuclear antibody (1000 times, shaggy pattern), positive anti ds-DNA antibody and hypocomplementemia. Furthermore, proteinuria was pointed out. Renal biopsy showed focal segmental glomerulonephritis with active necrotizing lesion (type III nephritis). Lupus myocarditis and nephritis was diagnosed. After prednisolone (80 mg/day) was administered. left ventricular function and hypocomplementemia improved. The ACE inhibitor was also used for proteinuria. In spite of a little amount of blood transfusion, he showed hepatic hemosiderosis. We suspect that the cause of hemosiderosis was related chronic inflammation of active lupus. It was treated with Erythropoietin.

The Persistence of Illicit Drug Smoke Residues and their Recovery from Common Household Surfaces

PubMed Central

Bitter, Julie L.

2016-01-01

Third-hand smoke is the residue left remaining on surfaces during smoking events, and is composed of particles and vapors that form upon heating. The phrase “third-hand smoke” is primarily used to describe nicotine and other chemicals from cigarettes, but any residues formed from the smoking of various substances could be classified similarly. There has been an increasing body of research on third-hand smoke from cigarettes in the last decade, but little has been done in regards to understanding the persistence of particles and vapors from illicit drugs. In this work, small samples of cocaine and methamphetamine were volatilized to produce an illicit drug smoke that was collected onto various surface materials and left exposed to ambient conditions over 672 hours (four weeks). Chemical analyses by electrospray ionization-mass spectrometry of residues on silicon, plastic, laminate, and artificial leather surfaces indicated a rapid decrease in recovery of the parent molecule, with varied formation of decomposition products over the first 168 hours of exposure. Measurable amounts of the parent molecule were still present after 672 hours, exhibiting a strong persistence of these drugs on various household materials. This is important in a forensic science context, as third-hand smoke residues could provide a viable source of trace evidence previously not utilized. PMID:27328798

The Neurobiological Grounding of Persistent Stuttering: from Structure to Function.

PubMed

Neef, Nicole E; Anwander, Alfred; Friederici, Angela D

2015-09-01

Neuroimaging and transcranial magnetic stimulation provide insights into the neuronal mechanisms underlying speech disfluencies in chronic persistent stuttering. In the present paper, the goal is not to provide an exhaustive review of existing literature, but rather to highlight robust findings. We, therefore, conducted a meta-analysis of diffusion tensor imaging studies which have recently implicated disrupted white matter connectivity in stuttering. A reduction of fractional anisotropy in persistent stuttering has been reported at several different loci. Our meta-analysis revealed consistent deficits in the left dorsal stream and in the interhemispheric connections between the sensorimotor cortices. In addition, recent fMRI meta-analyses link stuttering to reduced left fronto-parieto-temporal activation while greater fluency is associated with boosted co-activations of right fronto-parieto-temporal areas. However, the physiological foundation of these irregularities is not accessible with MRI. Complementary, transcranial magnetic stimulation (TMS) reveals local excitatory and inhibitory regulation of cortical dynamics. Applied to a speech motor area, TMS revealed reduced speech-planning-related neuronal dynamics at the level of the primary motor cortex in stuttering. Together, this review provides a focused view of the neurobiology of stuttering to date and may guide the rational design of future research. This future needs to account for the perpetual dynamic interactions between auditory, somatosensory, and speech motor circuits that shape fluent speech.

Glucocorticoid (GC) excess, including Cushing's syndrome, is a common cause of secondary osteoporosis. Thirty to fifty percent of Cushing's syndrome patients experience non-traumatic fractures, which is often the presenting manifestation of Cushing's syndrome. However, there have been rare cases of Cushing's syndrome diagnosed only based upon bone manifestations. We describe a case of Cushing's syndrome that was diagnosed in a 44-year-old woman who initially visited our hospital due to multiple non-traumatic rib fractures. She did not exhibit any other manifestations of Cushing's syndrome such as moon face, buffalo hump or abdominal striae. Initially, we evaluated her for bone metastases from a cancer of unknown origin, but there was no evidence of metastatic cancer. Instead, we found a left adrenal incidentaloma. As a result of the hormone study, she was diagnosed as having Cushing's syndrome. Interestingly, her bony manifestation of Cushing's syndrome, which was evident in the bone scan and bone mineral densitometry, completely recovered after a left adrenalectomy. Therefore, the possibility of Cushing's syndrome as a cause of secondary osteoporosis should be considered in young patients with non-traumatic multiple fractures, with or without any other typical features of Cushing's syndrome.

Delinquent youth have substantial trauma exposure, with life-course persistent delinquents [LCPD] demonstrating notably elevated cross-diagnostic psychopathology and cognitive deficits. Because adolescents remain in the midst of brain and neurocognitive development, tailored interventions are key to improving functional outcomes. This structural magnetic resonance imaging study compared neuroanatomical profiles of 23 LCPD and 20 matched control adolescent boys. LCPD youth had smaller overall gray matter, and left hippocampal, volumes alongside less cortical surface area and folding within the left pars opercularis and supramarginal cortex. LCPD youth had more adversity-related exposures, and their higher Cumulative Trauma, Adversity and Grief [C-TAG] symptoms were associated with less surface area and folding in the pars opercularis and lingual gyrus. Neuroanatomical differences between LCPD and control youth overlap with data from both maltreatment and antisocial literatures. The affected left frontal regions also share connections to language- and executive-related functions, aligning well with LCPD youths' cognitive and behavioral difficulties. These data also dovetail with research suggesting the possibility of neurodevelopmental delays or disruptions related to cumulative adversity burden. Thus, concurrent treatment of LCPD youths' C-TAG symptoms and, cognitive deficits with overlapping neuroanatomical bases, may be most effective in improving outcomes and optimizing neurodevelopmental trajectories.

We report a 1-month-old infant diagnosed with an aorta-left ventricular tunnel, ventricular septal defect, and right coronary atresia with right ventricular sinusoids. The patient's anatomy and physiology did not indicate right-ventricular-dependent coronary circulation, and therefore right ventricular decompression could be performed without compromising coronary perfusion during surgical correction. A detailed understanding of the coronary anatomy is critical in managing this defect when coronary anomalies are present.

A seven-month-old, neutered male Catahoula leopard dog cross was presented for recurrent urethral obstruction and intermittent hematuria. After exploratory laparotomy and ventral cystotomy, unilateral idiopathic renal hematuria was diagnosed based on gross observation of hematuria from the left ureteral catheter. The hematuria resolved after nephrectomy of the left kidney. The histopathological diagnosis was multifocal, acute congestion and intratubular hemorrhage. Although idiopathic renal hematuria has been described previously, this puppy was unique because the hematuria caused recurrent, complete urethral obstruction.

Symptom of herpes zoster is sometimes difficult to distinguish from sciatica induced by spinal diseases, including lumbar disc herniation and spinal canal stenosis. Here we report a case of sciatica mimicking lumbar canal stenosis. A 74-year-old Chinese male patient visited our hospital for left-sided sciatic pain upon standing or walking for 5 min of approximately 1 month's duration. At the first visit to our hospital, there were no skin lesions. A magnetic resonance imaging showed spinal canal stenosis between the 4th and 5th lumbar spine. Thus, we diagnosed the patient with sciatica induced by spinal canal stenosis. We considered decompression surgery for the stenosis of 4th and 5th lumbar spine because conservative therapy failed to relieve the patient's symptom. At that time, the patient complained of a skin rash involving his left foot for several days. A vesicular rash and erythema were observed on the dorsal and plantar surfaces of the great toe and lateral malleolus. The patient was diagnosed with herpes zoster in the left 5th lumbar spinal nerve area based on clinical findings, including the characteristics of the pain and vesicular rash and erythema in the 5th lumbar spinal dermatome. The patient was treated with famciclovir (1,500 mg/day) and non-steroidal anti-inflammatory drugs. After 1 week of medication, the skin rash resolved and pain relief was obtained. In conclusion, spinal surgeons should keep in mind herpes zoster infection as one of the possible differential diagnoses of sciatica, even if there is no typical skin rash.

Abstract Aims Cardiac involvement in sarcoidosis is reported in up to 30% of patients. Left ventricular involvement demonstrated by contrast‐enhanced cardiac magnetic resonance has been well validated. We sought to determine the prevalence and distribution of right ventricular late gadolinium enhancement in patients diagnosed with pulmonary sarcoidosis. Methods and results We prospectively evaluated 87 patients diagnosed with pulmonary sarcoidosis with contrast‐enhanced cardiac magnetic resonance for right ventricular involvement. Pulmonary artery pressures were non‐invasively evaluated with Doppler echocardiography. Patient characteristics were compared between the groups with and without right ventricular involvement, and right ventricular enhancement was correlated with pulmonary hypertension, ventricular mass, volume, and systolic function. Left ventricular late gadolinium enhancement was demonstrated in 30 patients (34%). Fourteen patients (16%) had right ventricular late gadolinium enhancement, with sole right ventricular enhancement in only two patients. The pattern of right ventricular enhancement consisted of right ventricular outflow tract enhancement in 1 patient, free wall enhancement in 8 patients, ventricular insertion point enhancement in 10 patients, and enhancement of the right side of the interventricular septum in 11 patients. Pulmonary arterial hypertension correlated with the presence of right ventricular enhancement (P < 0.001). Right ventricular enhancement correlated with systolic ventricular dysfunction (P < 0.001), hypertrophy (P = 0.001), and dilation (P < 0.001). Conclusions Right ventricular enhancement was present in 16% of patients diagnosed with pulmonary sarcoidosis and in 48% of patients with left ventricular enhancement. The presence of right ventricular enhancement correlated with pulmonary arterial hypertension, right ventricular systolic dysfunction, hypertrophy, and dilation. PMID:29154434

Three dogs were examined for clinical signs ultimately attributed to systemic fungal infections. One dog was evaluated for chronic, ulcerated dermal lesions and lymphadenomegaly; one dog was examined for acute onset of unilateral blepharospasm; and one dog had diarrhea and hematochezia. Two of the dogs were diagnosed with blastomycosis (one with disseminated disease and the other with the disease localized to the left eye). The third dog was diagnosed with disseminated histoplasmosis. None of the dogs originated from, or had traveled to, typical regions endemic for these fungal diseases. All diagnoses were established from histopathology and either polymerase chain reaction (PCR) or cytology and culture. The two dogs diagnosed with blastomycosis were treated with either itraconazole or ketoconazole with apparent resolution of the infections. The dog with ocular involvement had an enucleation prior to beginning therapy. The dog diagnosed with histoplasmosis was euthanized without treatment. In patients with characteristic clinical features, systemic fungal infections should still be considered as differential diagnoses regardless of their travel history.

Lumbo-costo-vertebral syndrome (LCVS) is a rare type of lumbar hernia with associated abnormalities of the vertebral bodies, ribs, and trunk muscles. Only a few cases have been reported in the literature, all of which were diagnosed after birth. We present a case of LCVS diagnosed early in the second trimester of pregnancy using two- and three-dimensional ultrasound. In our case, the associated anomalies were: multiple costovertebral anomalies, lumbar hernia, anal imperforation, left hand supernumerary digit, and clubfoot.

Purpose The purpose of the present investigation is to differentiate children using cochlear implants (CIs) who did or did not achieve age-appropriate language scores by midelementary grades and to identify risk factors for persistent language delay following early cochlear implantation. Materials and Method Children receiving unilateral CIs at young ages (12–38 months) were tested longitudinally and classified with normal language emergence (n = 19), late language emergence (n = 22), or persistent language delay (n = 19) on the basis of their test scores at 4.5 and 10.5 years of age. Relative effects of demographic, audiological, linguistic, and academic characteristics on language emergence were determined. Results Age at CI was associated with normal language emergence but did not differentiate late emergence from persistent delay. Children with persistent delay were more likely to use left-ear implants and older speech processor technology. They experienced higher aided thresholds and lower speech perception scores. Persistent delay was foreshadowed by low morphosyntactic and phonological diversity in preschool. Logistic regression analysis predicted normal language emergence with 84% accuracy and persistent language delay with 74% accuracy. Conclusion CI characteristics had a strong effect on persistent versus resolving language delay, suggesting that right-ear (or bilateral) devices, technology upgrades, and improved audibility may positively influence long-term language outcomes.

Moyamoya disease with special complications, including Graves' disease, is called as moyamoya syndrome. A 22-year-old Japanese woman had left middle cerebral artery (MCA) territory infarction complicated with Graves' disease. She had right-sided hemiparesis that deteriorated on day 8 with the infarct growth and thyrotoxicosis. On angiogram, the left MCA was occluded at the origin without moyamoya vessels. Positron emission tomography (PET) revealed misery-perfusion phenomenon in the left MCA territory. After initiation of the antithyroid therapy, her hemiparesis became milder. Seventeen months later, her thyroid function was normalized and net-like collateral moyamoya vessels proliferated in the left MCA territory. Misery-perfusion phenomenon persisted on PET. This report is unique in the point of neurologic recovery of the moyamoya patient right after initiation of antithyroid medication without radiological improvement.

Despite the robotic surgery is widely applied, sleeve lobectomy for lung cancer using the Da Vinci surgical system is still less performed. We described a sleeve lobectomy for adenocarcinoma located at the left lower lobe using the Da Vinci surgical system. A case of 57-year old female referred to our hospital. Computed tomography scan showed an occupation located at the left lower lobe and adenocarcinoma project from the lobe bronchus was diagnosed by bronchoscope examination. A sleeve lobectomy was performed using the Da Vinci surgical system and the postoperative recovery was uneventful. Robotic thoracic surgery is feasible to perform sleeve lobectomy inspite of inadequate experience.

A 22-year-old pregnant female with pyelonephritis was found to have a 26-mm left renal artery aneurysm with unknown right kidney agenesis diagnosed by magnetic resonance imaging. Computed tomographic angiography with 3-dimensional reconstructions confirmed a saccular aneurysm localized at the bifurcation of the left posterior segmental artery. The patient ultimately underwent successful ex vivo left renal artery aneurysm repair with autotransplantation. Pathologic evaluation of the resected aneurysm confirmed the diagnosis of fibromuscular dysplasia. Fibromuscular dysplasia is the most common cause of renal artery stenosis and renovascular hypertension and can, in rare cases, be associated with the development of renal artery aneurysms. © The Author(s) 2014.

Background— The incidence and clinical significance of persistent T2 hyperintensity after acute ST-segment–elevation myocardial infarction (STEMI) is uncertain. Methods and Results— Patients who sustained an acute STEMI were enrolled in a cohort study (BHF MR-MI: NCT02072850). Two hundred eighty-three STEMI patients (mean age, 59±12 years; 75% male) had cardiac magnetic resonance with T2 mapping performed at 2 days and 6 months post-STEMI. Persisting T2 hyperintensity was defined as infarct T2 >2 SDs from remote T2 at 6 months. Infarct zone T2 was higher than remote zone T2 at 2 days (66.3±6.1 versus 49.7±2.1 ms; P<0.001) and 6 months (56.8±4.5 versus 49.7±2.3 ms; P<0.001). Remote zone T2 did not change over time (mean change, 0.0±2.7 ms; P=0.837), whereas infarct zone T2 decreased (−9.5±6.4 ms; P<0.001). At 6 months, T2 hyperintensity persisted in 189 (67%) patients, who were more likely to have Thrombus in Myocardial Infarction flow 0 or 1 in the culprit artery (P=0.020), incomplete ST-segment resolution (P=0.037), and higher troponin (P=0.024). Persistent T2 hyperintensity was associated with NT-proBNP (N-terminal pro-B-type natriuretic peptide) concentration (0.57 on a log scale [0.42–0.72]; P=0.004) and the likelihood of adverse left ventricular remodeling (>20% change in left ventricular end-diastolic volume; 21.91 [2.75–174.29]; P=0.004). Persistent T2 hyperintensity was associated with all-cause death and heart failure, but the result was not significant (P=0.051). ΔT2 was associated with all-cause death and heart failure (P=0.004) and major adverse cardiac events (P=0.013). Conclusions— Persistent T2 hyperintensity occurs in two thirds of STEMI patients. Persistent T2 hyperintensity was associated with the initial STEMI severity, adverse remodeling, and long-term health outcome. Clinical Trial Registration— URL: http://www.clinicaltrials.gov.

1991-01-01

Atrial isomerism is very rare in adolescence. Two cases of left atrial isomerism are reported here in 2 females, aged 21 and 19 years. They had presented with cyanosis and dyspnea since childhood. High kilovoltage filter films showed a bilateral morphologically left bronchus. Cardiac catheterization in Case 1 revealed normal pulmonary artery pressure, severe subvalvular pulmonic stenosis, a double outlet right ventricle, a significant oxygen step-up at the atrial level and moderate systemic oxygen desaturation; while Case 2 disclosed pulmonary hypertension and mild systemic oxygen desaturation. Both cases had the following anatomical features: ipsilateral connection of pulmonary veins to the bilateral morphological left atrium; interrupted inferior vena cave with azygos or hemiazygos continuation; total anomalous hepatic venous return to the right-sided atrium; complete atrioventricular canal. The diagnoses were confirmed in both cases at surgical correction.

To report a case of circumferential neuroepithelial cyst of the ciliary body presenting with pigment dispersion (PD) and ocular hypertension. 48-year-old female patient presented with a complaint of pain in the left eye. On examination, visual acuity of the left eye was 0.9, and the intraocular pressure was 48 mmHg. Biomicroscopic anterior segment examination of the left eye revealed 4+ pigmented cells in the anterior chamber. Active PD from the pupillary region at 11 o'clock was noticed at the time of the examination. Ultrasound biomicroscopy demonstrated 360º cystic lesions of the ciliary body in the left eye. The patient was diagnosed as neuroepithelial cyst of the ciliary body. Our case is unique as it is the first case of circumferential neuroepithelial ciliary body cyst presenting with acute PD and ocular hypertension.

Introduction of biologic agents in inflammatory bowel disease (IBD) has increased the likelihood of disease remission. Despite resolution of active inflammation, a subset of IBD patients report persistent defecatory symptoms. To evaluate a group of patients with inflammatory bowel disease with suspected functional defecatory disorders, by use of anorectal manometric testing and subsequent biofeedback therapy. A group of IBD patients with persistent defecatory problems despite clinical improvement were included in this study. These patients had no evidence of left-sided disease. Endoscopic and radiographic study findings and timing in relation to the manometry study were recorded. Anorectal manometry was performed by the standard protocol and included rectal sensory assessment, ability to expel a balloon, and pressure dynamics with simulated defecation. Thirty IBD patients (Crohn's 23 patients; ulcerative colitis six patients) presented with defecatory disorders including constipation (67%) increased stooling (10%), and rectal urgency and/or incontinence and rectal pain (6%). All but one patient had anorectal manometric criteria of dyssynergia (presence of anismus motor pattern and inability to expel the balloon). Of the patients who completed biofeedback therapy, 30% had a clinically significant (≥7-point) improvement in SIBDQ score, with a reduction in health-care utilization after a six-month period (p=0.02). Despite remission, some inflammatory bowel disease patients have persistent defecatory symptoms. Defecatory symptoms may not be predictive of an underlying inflammatory disorder. Lack of inflammatory activity and absence of left-sided disease should prompt investigation of functional disorders. Anorectal manometric testing and biofeedback therapy for patients with a diagnosis of dyssynergia may be a useful therapy.

Abnormal connection of the right superior caval vein to the left atrium is an uncommon systemic vein drainage anomaly, with only a few cases reported among congenital heart disease (CHD), around 20 cases published in the medical literature. The inferior vena cava connection with the left atrium, also very rare, can appear directly or in heterotaxy. Clinical suspicion arises due to the presence of cyanosis in the absence of other specific clinical signs (without other associated CHD). We present the cases of two children with abnormal superior and inferior systemic venous return. The first case is an abnormal connection of right superior vena cava to the left atrium associated with persistent left superior vena cava draining into the right atrium through the coronary sinus. The second case is an interruption of the inferior vena cava with hemiazygos continuation, drained into the left superior vena cava, which drained into the left atrium. The diagnosis was imagistic - echocardiography and angiography. Surgical treatment solutions vary from one case to another, usually following anatomic correction. Hypoxia accompanied by cyanosis must bring into question the pathology of systemic venous drainage anomaly, after other common causes have been excluded. Surgery is indicated in all cases due to the risk associated with the presence of right-to-left shunt.

To explore if CHA2DS2 VASc score can predict substrate for persistent atrial fibrillation ( AF) and outcome post catheter ablation of AF. From January 2011 to December 2012,116 patients underwent catheter ablation of persistent AF in our department and were enrolled in this study. CHA2DS2VASc score was calculated as follows: two points were assigned for a history of stroke or transient ischemic attack and age ≥ 75 and 1 point each was assigned for age ≥ 65, a history of hypertension, diabetes,recent cardiac failure, vessel disease, female. Left atrial geometry ( LA) was reconstructed with a 3.5 mm tip ablation catheter with fill-in threshold 10 in CARTO system. The mapping catheter was stabled at each endocardial location for at least 3 seconds for recording. The electrogram recordings at each endocardial location were analyzed with a custom software embedded in the CARTO mapping system. Interval confidence level (ICL) was used to characterize complex fractionated atrial electrograms (CFAEs) . As the default setting of the software, ICL more than or equal to 7 was considered sites with a highly repetitive CFAEs complex. CFAEs index was defined as the fraction of area of ICL more than or equal to 7 to the left atrial surface. The CFAEs index and outcome of catheter ablation among different CHA2DS2VASc groups were compared. Of the 116 patients, CHA2DS2VASc was 0 in 33 patients, 1 in 31 patients and ≥ 2 in 52 patients. Left atrial surface ((121.2 ± 18.9) cm2, (133.6 ± 23.8) cm2, (133.9 ± 16.1) cm2, P = 0.008), left atrial volume ((103.6 ± 24.8) ml, (118.3 ± 27.8) ml, (120.9 ± 20.9) ml, P = 0.005) and CFAEs index (44.6% ± 22.4%, 54.2% ± 22.2%, 58.7% ± 23.1%, P = 0.023) increased in proportion with increasing CHA2DS2VASc. ICLmax, ICLmin and CFAEs spatial distribution were similar among the three groups. During the mean follow-up of (13 ± 8) months, the recurrence rate were 36.4%, 35.5%, 55.8% among the three groups (P = 0.025). A high CHA2DS2VASc score is associated with extensive AF substrate and higher recurrence rate post catheter ablation of persistent AF.

No previous reports have shown an association between location of diverticular disease (DD) and the irritable bowel syndrome (IBS). We included 1,009 consecutive patients undergoing total colonoscopy in seven centers in Japan from June 2013 to September 2013. IBS was diagnosed using Rome III criteria, and diverticulosis was diagnosed by colonoscopy with transparent soft-short-hood. Left-sided colon was defined as sigmoid colon, descending colon, and rectum. Right-sided colon was defined as cecum, ascending colon, and transverse colon. We divided the patients into IBS and non-IBS groups and compared characteristics. Patient characteristics included mean age, 64.2±12.9 years and male:female ratio, 1.62:1. Right-sided DD was identified in 21.6% of subjects. Left-sided and bilateral DD was identified in 6.6 and 12.0% of subjects, respectively. IBS was observed in 7.5% of subjects. Multiple logistic regression analysis showed left-sided DD (odds ratio, 3.1; 95% confidence interval (CI): 1.4-7.1; P=0.0060) and bilateral DD (odds ratio, 2.6; 95% CI, 1.3-5.2; P=0.0070) were independent risk factors for IBS. Right-sided DD was not a risk factor for IBS. Our data showed that the presence of left-sided and bilateral DD, but not right-sided disease, was associated with a higher risk of IBS, indicating that differences in pathological factors caused by the location of the DD are important in the development of IBS. Clarifying the specific changes associated with left-sided DD could provide a better understanding of the pathogenic mechanisms of IBS (Trial registration # R000012739).

Persistent hyperplastic primary vitreous is a spectrum of congenital ocular abnormalities characterized by leukocoria, microphthalmia, cataracts, extensive intravitreal hemorrhage, persistence of the hyaloid artery, glaucoma, and retinal detachment. It might be isolated or associated with congenital syndromes such as trisomy 13, Walker-Warburg syndrome, and Norrie disease. We present 2 cases of persistent hyperplastic primary vitreous diagnosed by prenatal sonography in the early third trimester. Bilateral hyperechoic lenses and retinal nonattachment were detected in the sonographic examination of the first case, whereas irregular echogenic bands between the lenses and posterior walls of the eyes were prominent in the second case. In both of the cases, ocular findings were accompanied by intracranial findings, including severe hydrocephalus, an abnormal gyral pattern, and cerebellar hypoplasia, suggesting the diagnosis of Walker-Warburg syndrome. We also present a review of the literature regarding the prenatal diagnosis of this malformation.

Use of ultrasonography to diagnose large colon volvulus in horses.

To describe the use of ultrasonography to diagnose large colon volvulus (LCV) in horses. Descriptive report. 4 horses with clinical signs of abdominal pain. Each horse was administered analgesic agents for pain control and placed in stocks. Ultrasonographic evaluations were performed with a 3.5-MHz sector scanning transducer that was placed parallel to the long axis of the horse (longitudinal imaging) over an area of the left ventral aspect of the abdomen. The boundaries of the evaluated region included the ventral midline, 2 vertical lines at the level of the left 10th and 17th intercostal spaces, and a horizontal line between the 2 vertical lines at the level of the costal arch of the left 10th intercostal area. In all horses, nonsacculated large colon was identified ultrasonographically in the left ventral portion of the abdomen; this finding was considered indicative of LCV. In 3 horses, the LCV involved intestinal rotation of 180 degrees, whereas in 1 horse, the LCV involved intestinal rotation of 540 degrees. As confirmed by surgical or postmortem findings, the degree and location of the volvulus were correctly estimated from ultrasonographic images. In horses, this method of diagnosis of LCV appears to be of value regardless of the location at which the rotation of the large colon occurs. Ultrasonographic findings may aid in the earlier diagnosis of LCV in horses, especially at an early stage of the disease when other clinical signs are equivocal.

Atrial fibrillation transcatheter ablation (TCA) is, within available atrial fibrillation rhythm control strategies, one of the most effective. To potentially improve ablation outcome in case of recurrent atrial fibrillation after a first procedure or in presence of structural myocardial disease, isolation of the pulmonary veins may be associated with extensive lesions within the left atrium. To avoid rare, but potentially life-threatening, complications, thorough knowledge and assessment of left atrium anatomy and its relation to structures in close proximity are, therefore, mandatory. Aim of the present study is to describe, by cardiac computed tomography, the anatomic relationship between aortic root, left coronary artery and left atrium in patients undergoing atrial fibrillation TCA. The cardiac computed tomography scan of 21 patients affected by atrial fibrillation was elaborated to segment left atrium, aortic root and left coronary artery from the surrounding structures and the following distances measured: left atrium and aortic root; left atrium roof and aortic root; left main coronary artery and left atrium; circumflex artery and left atrium appendage; and circumflex artery and mitral valve annulus. Above all, the median distance between left atrium and aortic root (1.9, 1.5-2.1 mm), and between circumflex artery and left atrium appendage ostium (3.0, 2.1-3.4 mm) were minimal (≤3 mm). None of measured distances significantly varied between patients presenting paroxysmal versus persistent atrial fibrillation. The anatomic relationship between left atrium and coronary arteries is extremely relevant when performing atrial fibrillation TCA by extensive lesions. Therefore, at least in the latter case, preablation imaging should be recommended to avoid rare, but potentially life-threatening, complications with the aim of an as well tolerated as possible procedure.

Persistent genital arousal disorder (PGAD) is characterized by intrusive sexual arousal that is unresolvable via sexual activity and persists for an extended period of time. PGAD's etiology is unknown, and it has no established treatments. This case study reports on a 71-year-old female patient diagnosed with PGAD who received 9 sessions of hypnotherapy. The following measures were administered at baseline and follow-up: Hospital Anxiety and Depression Scale, Center for Epidemiologic Studies Depression Scale, Pittsburgh Sleep Quality Index, and visual analogue measurements of quality of life, intensity of symptoms, and marital interference. At follow-up, there were significant improvements in all measures. Given the currently limited alternatives for treatment, this case study suggests that hypnotherapy may be beneficial for some patients with PGAD.

Background Left ventricular (LV) diastolic dysfunction is associated with new-onset atrial fibrillation (AF), and the estimation of elevated LV filling pressures by E/e' ratio is related to worse outcomes in patients with AF. However, it is unknown if restoring sinus rhythm reverses this process. Objective To evaluate the impact of AF ablation on estimated LV filling pressure. Methods A total of 141 patients underwent radiofrequency (RF) ablation to treat drug-refractory AF. Transthoracic echocardiography was performed 30 days before and 12 months after ablation. LV functional parameters, left atrial volume index (LAVind), and transmitral pulsed and mitral annulus tissue Doppler (e' and E/e') were assessed. Paroxysmal AF was present in 18 patients, persistent AF was present in 102 patients, and long-standing persistent AF in 21 patients. Follow-up included electrocardiographic examination and 24-h Holter monitoring at 3, 6, and 12 months after ablation. Results One hundred seventeen patients (82.9%) were free of AF during the follow-up (average, 18 ± 5 months). LAVind reduced in the successful group (30.2 mL/m2 ± 10.6 mL/m2 to 22.6 mL/m2 ± 1.1 mL/m2, p < 0.001) compared to the non-successful group (37.7 mL/m2 ± 14.3 mL/m2 to 37.5 mL/m2 ± 14.5 mL/m2, p = ns). Improvement of LV filling pressure assessed by a reduction in the E/e' ratio was observed only after successful ablation (11.5 ± 4.5 vs. 7.1 ± 3.7, p < 0.001) but not in patients with recurrent AF (12.7 ± 4.4 vs. 12 ± 3.3, p = ns). The success rate was lower in the long-standing persistent AF patient group (57% vs. 87%, p = 0.001). Conclusion Successful AF ablation is associated with LA reverse remodeling and an improvement in LV filling pressure. PMID:25590928

Complete electrical isolation of pulmonary veins (PVs) remains the cornerstone of ablation therapy for atrial fibrillation. Entrance block without exit block has been reported to occur in 40% of the patients. Far-field capture (FFC) can occur during pacing from the superior PVs to assess exit block, and this may appear as persistent conduction from PV to left atrium (LA). To facilitate accurate assessment of exit block. Twenty consecutive patients with symptomatic atrial fibrillation referred for ablation were included in the study. Once PV isolation (entrance block) was confirmed, pacing from all the bipoles on the Lasso catheter was used to assess exit block by using a pacing stimulus of 10 mA at 2 ms. Evidence for PV capture without conduction to LA was necessary to prove exit block. If conduction to LA was noticed, pacing output was decreased until there was PV capture without conduction to LA or no PV capture was noted to assess for far-field capture in both the upper PVs. All 20 patients underwent successful isolation (entrance block) of all 76 (4 left common PV) veins: mean age 58 ± 9 years; paroxysmal atrial fibrillation 40%; hypertension 70%, diabetes mellitus 30%, coronary artery disease 15%; left ventricular ejection fraction 55% ± 10%; LA size 42 ± 11 mm. Despite entrance block, exit block was absent in only 16% of the PVs, suggesting persistent PV to LA conduction. FFC of LA appendage was noted in 38% of the left superior PVs. FFC of the superior vena cava was noted in 30% of the right superior PVs. The mean pacing threshold for FFC was 7 ± 4 mA. Decreasing pacing output until only PV capture (loss of FFC) is noted was essential to confirm true exit block. FFC of LA appendage or superior vena cava can masquerade as persistent PV to LA conduction. A careful assessment for PV capture at decreasing pacing output is essential to exclude FFC.

Major depressive disorder (MDD) is a prevalent and frequently comorbid psychiatric disorder. This study evaluates the development of depressive symptoms, MDD diagnosis, and suicidal ideation in a high-risk sample (N=524) diagnosed with conduct disorder (CD) and substance use disorder (SUD) symptoms as youth and re-assessed approximately 6.5 years later. Dual trajectory classes of both alcohol and other drug use (AOD) and antisocial behavior (ASB), previously identified using latent class growth analyses (LCGA), were used to predict depression outcomes. The Dual Chronic, Increasing AOD/Persistent ASB, and Decreasing Drugs/Persistent ASB classes had higher past-week depression scores, more past-year MDD symptoms, and were more likely to have past-year MDD than the Resolved class. The Dual Chronic and Decreasing Drugs/Persistent ASB classes also had more past-year MDD symptoms than the Persistent AOD/Adolescent ASB class. Youth at highest risk for developing or maintaining depression in adulthood had the common characteristic of persistent antisocial behavior. This suggests young adulthood depression is associated more with persistent antisocial behavior than with persistent substance use in comorbid youth. As such, interventions targeting high-risk youth, particularly those with persistent antisocial behavior, are needed to help reduce the risk of severe psychosocial consequences (including risk for suicide) in adulthood.

Although inappropriate left ventricular mass has been associated with clustered cardiac geometric and functional abnormalities, its predictive value in patients with coronary artery disease is still unknown. This study examined the association of inappropriate left ventricular mass with clinical outcomes in patients with angina pectoris and normal ejection fraction. Consecutive patients diagnosed with angina pectoris whose ejection fraction was normal were recruited from 2008 to 2012. Inappropriate left ventricular mass was determined when the ratio of actual left ventricular mass to the predicted one exceeded 150%. The primary endpoint was a composite of all-cause death, nonfatal myocardial infarction, and nonfatal stroke. Clinical outcomes between the inappropriate and appropriate left ventricular mass group were compared before and after propensity matching. Of the total of 1515 participants, 18.3% had inappropriate left ventricular mass. Patients with inappropriate left ventricular mass had a higher composite event rate compared with those with appropriate left ventricular mass (11.2 vs. 6.6%, P=0.010). Multivariate Cox regression analyses showed that inappropriate left ventricular mass was an independent risk factor for adverse events (adjusted hazard ratio, 1.59; 95% confidence interval, 1.03-2.45; P=0.035). The worse outcome in patients with inappropriate left ventricular mass was further validated in a propensity matching cohort and patients with the traditional definition of left ventricular hypertrophy. Inappropriate left ventricular mass was associated with an increased risk of adverse events in patients with angina pectoris and normal ejection fraction.

To provide results from the largest study of new daily persistent headache patients to date and specifically evaluate if patients with primary new daily persistent headache develop white matter abnormalities or infarct-like lesions on neuroimaging. Retrospective analysis of patient medical records utilizing an electronic medical record system. All patients were seen at a headache specialty clinic by a single headache neurologist and diagnosed with primary new daily persistent headache during the time period of January 2009 to January 2013. Altogether, 97 patients were diagnosed with primary new daily persistent headache (65 women and 32 men). The mean average age of onset was slightly younger in women than men: 32.4 years vs. 35.8 years. In total, 84 of the 97 new daily persistent headache patients had no white matter abnormalities or infarct-like lesions on magnetic resonance imaging with a gender distribution of 56 women and 28 men. The mean age of onset of this white matter negative subgroup was 31.1 years. Of these individuals, 36% had cardiovascular/cerebrovascular risk factors and 44% had a history of migraine. Only 13 new daily persistent headache patients (nine women, four men) demonstrated white matter abnormalities on magnetic resonance imaging. None had infarct-like lesions. The mean age of onset of this white matter positive subgroup was 54.2 years, significantly older than the white matter negative population (p < .05). All new daily persistent headache patients in the white matter positive subgroup had cardiovascular/cerebrovascular risk factors and dual risk factors were noted in seven of 13 patients. Only 23% had a migraine history. Almost 40% of the patients in the white matter negative group were imaged 3 years after headache onset and at least six patients were imaged at least 9 years or more after onset of new daily persistent headache. Triggering events in both white matter lesion positive and negative populations were typical of the new daily persistent headache population as a whole and not specific to the presence or absence of brain imaging lesions except for a post-surgery trigger, which was significantly more likely to occur in the white matter positive group. Migraine associated symptoms occurred in 77% of the white matter negative subgroup compared with 46% of the white matter positive subgroup, which was a significant difference. White matter abnormalities and infarct-like lesions do not appear to occur in primary new daily persistent headache patients. Only new daily persistent headache patients with risk factors (cardiovascular/cerebrovascular or migraine) developed white matter abnormalities on brain magnetic resonance imaging. No patient with new daily persistent headache developed infarct-like lesions. New daily persistent headache triggering events (outside of possibly post-surgery) or the presence of migrainous symptoms did not appear to enhance the development of white matter abnormalities. © International Headache Society 2015.

Purpose: Papillary carcinoma is the most frequent type of thyroid cancer and was considered the most benign of all thyroid carcinomas, with a low risk of distant metastases. However, there are some variants of papillary thyroid carcinoma that have affinity to spread in many organs, such as: lymph nodes, lungs and bones. Aim: The aim of this study was presentation of a case with papillary carcinoma of the thyroid gland, very persistent and resistant in treatment with I 131. Material and results: A man 56 years old were diagnosed with papillary carcinoma of thyroid gland. He underwent a surgical removal of the tumor and right lobe of thyroid gland. With histopathology examination, were confirmed follicular variant of papillary carcinoma pT4. Two weeks later he underwent total thyroidectomy and was treated with 100 mCi of J 131. Six months later, the value of thyroglobulin was found elevated above upper measured limits (more than 500 ng/ml). Patient underwent surgical removal of 10 metastatic lymph nodes in the left side of the neck and has been treated with 145 mCi of radioiodine I 131. The examination after 5 months shows elevation of thyroglobulin, more than 20000 ng/ml and focally uptake of J 131 in the left lung. Patient was treated once again with 150 mCi radioiodine J 131. Whole body scintigraphy was registered focal uptake of radioiodine in the middle of the left collarbone. After a month, patient refers the enlargement of the lymph node in the right side of the neck. Currently patient is being treated with kinase inhibitor drug sorafenib and ibandronate. We have identified first positive response in treatment. Enlarged lymph node in the neck was reduced and the patient began feeling better. Conclusion: This study suggests that some subtypes of papillary thyroid carcinoma appear to have more aggressive biological course. Subtypes of papillary thyroid carcinoma such as diffuse sclerosing carcinoma, tall cell or columnar cell and insular variants, appears to have more aggressive biological course and need early detection and other kind of treatment.

Based on the theories dealing with reorganization of the functional system, which are usually the basis of the treatment of aphasology, this paper has as its objective to analyse the evolution of the ability to communicate in a series of 43 right-handed persons with aphasia due to a cerebro-vascular accident of the left hemisphere, who attended sessions of neuropsychological treatment. The patients were grouped according to the type of aphasia initially diagnosed: global (G), Broca (B), conduction (C), anomia (A), transcortical motor (MT) and Wernicke (W). The output before and after treatment was evaluated using a scale from 0-6 points to grade the capacity of communication (comprehension-expression). In each group the 't' test was done to compare the average scores, initially and finally, both of comprehension and of expression. The results showed that group A had the most favourable course both of comprehension and of expression. Of the patients with a predominantly expression disorder, the best recovery was seen in groups C and MT. In group B verbal expression followed a very varied course. Those of G and W improved significantly, but great difficulty in communication persisted. Comparing expression in these two groups, those of W showed significantly more improvement than those of G, who showed very little improvement.

A 50-year-old female was diagnosed with vulvar cancer treated with left partial vulvectomy and bilateral lymphadenectomy. Ten months after her surgery, she presented with increased labial swelling, pain and discharge. Biopsy confirmed recurrence of squamous cell vulvar carcinoma. Incidentally, on restaging radiographic scans, she was found to have a large right ventricular mass which, after surgical debulking, was shown to be a squamous cell cancer of vulvar origin. She was commenced on chemotherapy with carboplatin and paclitaxel along with concurrent radiation therapy. Restaging PET scan showed persistent metastatic disease. She was switched to Cisplatin/Taxol after having hypersensitivity reaction to Carboplatin. She received 5 cycles with progression of disease in the follow up scans. She then received Nivolumab for 2 cycles. The patient then opted for comfort directed care given worsening functional status and progression of disease on repeat imaging. Secondary cardiac tumors are very rare and not extensively studied in oncology. Therefore, optimal management is not entirely clear. It is extremely rare for vulvar cancer to metastasize to the heart and only two cases have been reported in the literature. However, vulvar cancer metastasizing to the right ventricular cavity and endocardium has not been described before. We believe that this is the first ever such reported case.

Frontonasal dysplasia is a complex rare malformation, characterised by abnormalities involving the central portion of the face, especially the eyes, nose and forehead. It can manifest independently or associated with other abnormalities as part of some syndromes. The purpose of this case report was to describe a 5-year-old patient, diagnosed with frontonasal dysplasia. Among the abnormalities characterised with this disorder were ocular hypertelorism, broad nose tip with median notch, median facial cleft, bifid anterior skull, low set hairline, Poland's syndactyly and ankyloglossia. Consisted of behavioural management, oral hygiene instruction, prophylaxis, topical fluoride application, extraction of primary teeth, composite resin restorations and sealants in pits and fissures. Preformed metal crowns were also applied to the right and left primary maxillary second molars. Currently, the patient is 11 years-old in the permanent dentition and therefore was referred for corrective orthodontic and periodontal treatments due to the persistence of gingival retraction of the permanent mandibular right central incisor. The treatment in this case was directed to the promotion of oral health and orthodontic corrections, which are of fundamental importance due to medical, physical and social limitations of children affected by this syndrome, hindering healing and rehabilitative treatment. Paediatric dentists should be included in multidisciplinary teams providing care to patients with special needs, improving their quality of life.

ICA Occlusion by an ACTH-secreting pituitary adenoma post-TSS and irradiation

Occlusion of intracranial arteries by a pituitary adenoma with ensuing infarction is a rare occurrence. In this case study, we show the instance of a pituitary macroadenoma and apoplexy causing mechanical obstruction of the internal carotid artery with consequent infarction following transphenoidal surgery (TSS) and radiation therapy in a patient with Cushing's disease. We report a 44-year-old woman presented with amenorrhea and headaches. Necessary investigations, resection by TSS, and microscopic examination revealed an adenocorticotropin (ACTH)-secreting pituitary macroadenoma. The pituitary tumour recurred in subsequent years, resulting in the development of Cushing's disease and syndrome. Despite two more transphenoidal surgeries, radiotherapy, and medical suppressive therapy, the pituitary adenoma continued to enlarge, and the hypercortisolemia and Cushingoid symptoms persisted. A craniotomy was arranged as the next step in the treatment strategy. Only hours prior to the scheduled surgery, the patient developed left-sided hemiplegia, was diagnosed with acute occlusion of the right ICA and underwent an emergency bifrontal craniotomy with evacuation of the tumour and decompression. Pathological examination revealed evidence of apoplexy in the ACTH-secreting pituitary adenoma. This case demonstrates the vast scope of complications that can arise from pituitary adenomas despite combination therapy and forewarns clinicians to be prepared to manage these infrequent but conceivable occurrences.

Herpes simplex virus encephalitis (HSVE) is a medical emergency associated with high mortality and morbidity. Definitive diagnosis is established by history, clinical examination, neuroimaging studies, supportive electroencephalogram (EEG) findings, and cerebrospinal fluid (CSF) analysis. We report a case of HSVE presenting as a stroke mimic in a 76-year-old female with a history of atrial fibrillation on warfarin. She was admitted to our medical intensive care unit with intermittent fever, lethargy, and new onset left-sided hemiparesis. A computed tomography (CT) of the head showed a right middle cerebral artery (MCA) acute ischemic stroke with midline shift and a dense right MCA sign. Brain magnetic resonance imaging (MRI) showed evidence of acute stroke with consideration of herpes encephalitis. CSF analysis was positive for herpes simplex virus (HSV) type one. She recovered with high-dose intravenous acyclovir therapy. Our patient was a diagnostic dilemma, initially being diagnosed with an acute ischemic stroke and yet found to have HSVE, which mimicked an acute ischemic stroke. Delay in treatment may result in devastating clinical outcomes that may include severe cognitive, focal neurological deficits, persistent seizures, and even death. This case highlights the importance of a multidisciplinary approach and the need for increased awareness of an atypical presentation of HSVE among emergency physicians, neurologist, intensivists, and radiologists.

A new paradigm in benchmark absorption-scattering radiative transfer is presented that enables both the globally averaged and spatially resolved testing of climate model radiation parameterizations in order to uncover persistent sources of biases in the aerosol instantaneous radiative effect (IRE). A proof of concept is demonstrated with the Geophysical Fluid Dynamics Laboratory AM4 and Community Earth System Model 1.2.2 climate models. Instead of prescribing atmospheric conditions and aerosols, as in prior intercomparisons, native snapshots of the atmospheric state and aerosol optical properties from the participating models are used as inputs to an accurate radiation solver to uncover model-relevant biases. These diagnostic results show that the models' aerosol IRE bias is of the same magnitude as the persistent range cited ( 1 W/m2) and also varies spatially and with intrinsic aerosol optical properties. The findings underscore the significance of native model error analysis and its dispositive ability to diagnose global biases, confirming its fundamental value for the Radiative Forcing Model Intercomparison Project.

Scalp hyperkeratosis of childhood is most often associated with atopic or seborrheic dermatitis. However, in black children can be associated with tinea capitis. We undertook a retrospective study in all Sub-Saharan children presenting with chronic scalp scaling between June 2010 and June 2013, to determine whether chronic desquamation of the scalp is a clinical manifestation of tinea capitis. The criterion used to diagnose tinea capitis was a positive mycolological culture. Of the 23 Sub-Saharan African children attended, 12 (43.4%) presented with chronic scalp flaking. Mycological culture was performed in 9 of the 12 cases. The culture was positive in 6 out of 9, so 26% of the Sub-Saharan African children attended were diagnosed with tinea capitis. In 52.1% of the cases with persistent scalp scaling the culture was positive. In conclusion, chronic scaling of the scalp may well be the sole form of presentation of tinea capitis in Sub-Saharan children.

Diagnosis and treatment of branchial cleft anomalies in UKMMC: a 10-year retrospective study.

PubMed

Zaifullah, Syed; Yunus, Mohd Razif Mohamad; See, Goh Bee

2013-03-01

Branchial cleft anomalies result from abnormal persistence of branchial apparatus, which is located at the lateral part of the neck. These occur due to failure of obliteration of the branchial apparatus during embryonic development. Differential diagnoses of lateral neck mass are salivary gland or neurogenic neoplasms, paragangliomas, adenopathies, cystic hygroma or cystic metastasis from squamous cell carcinoma or thyroid papillary carcinoma. Clinically, a branchial cyst is smooth, round, fluctuant and non-tender, and usually occurs over the upper part of the neck, anterior to the sternocleidomastoid muscle. Sometimes, it may present as infected cyst (or abscess), a sinus or fistula. Surgical excision is the definitive treatment for branchial anomalies. The objective of the work was to study the demographic data, clinical presentation, definite diagnostic workup and treatment of patients diagnosed with branchial anomalies. This is a retrospective study of 26 patients who were diagnosed with branchial anomalies (branchial cyst and fistula), of which only 12 patients had data available between July 1999 and June 2009 at the Otorhinolaryngology, Head and Neck Surgery, Universiti Kebangsaan Malaysia Medical Centre. Twelve cases of branchial anomalies were seen, in which 10 patients had second branchial cyst anomalies, 1 had third branchial fistula and 1 had bilateral branchial lesion. There were seven females and five males. The age of the patients varied over a wide range (4-44 years), but the majority of the patients were in their second and third decade of life. All branchial anomalies occurred at the classical site; eight patients had left-sided neck lesion. Correct clinical diagnosis was made only in five patients (41.6 %). All patients underwent surgical excision with no reported recurrence. Branchial anomalies are frequently forgotten in the differential diagnosis of lateral neck swelling. Diagnosis is usually delayed, leading to improper treatment. The diagnosis of patients who present with lateral neck cystic swelling with or without episodes of recurrent neck abscess should be considered with a high suspicion for branchial anomalies. FNA cytology is a good investigative tool in reaching toward a diagnosis of branchial lesion, with the concurrent assistance of radiological modalities. Surgical excision is the gold standard treatment of lesions of branchial anomalies.

No air leak on PPV does not exclude tracheobronchial injury after blunt chest trauma.

Tracheobronchial injuries are commonly associated with persistent air leak with pneumothoraces especially when on positive pressure ventilation (PPV). Injuries with absence of these features together with collapse of the lung and consequent low arterial oxygen tension while on PPV are less well recognised. We present a patient with traumatic aortic dissection and preoperatively undiagnosed complete transaction of the left main bronchus following blunt chest trauma. He had no persistent air leak with lower lung lobe collapse despite undergoing PPV and had low arterial oxygen tension which failed to respond to appropriate oxygen therapy.

Coronary sinus ostial atresia (CSOA) with persistent left superior vena cava (LSVC) in the absence of an unroofed coronary sinus is a benign and rare anomaly that may be taken lightly in most instances. However, if overlooked in patients undergoing univentricular heart repair such as bidirectional Glenn or Fontan-type surgery, fatal surgical outcomes may occur due to coronary venous drainage failure. We report a case of CSOA with a persistent LSVC that was managed through coronary sinus rerouting during a total cavopulmonary connection, and provide a review of the literature regarding this rare anomaly.

The utility of bronchoscopy for the diagnosis of pulmonary Mycobacterium avium-intracellulare complex (MAC) disease has been reported; however, which patients require bronchoscopy remains unclear. Our objective was to identify the characteristics of the patients in whom bronchoscopy is needed for the diagnosis of MAC disease. Fifty-four patients with pulmonary MAC disease were divided into two groups according to established diagnostic criteria: 39 patients were diagnosed by sputum culture and 15 patients were diagnosed by bronchial lavage culture. We analysed the differences in demographic and clinical characteristics as well as microbiological and radiological data between the two groups. There were no significant differences in age, sex, smoking status, MAC species, underlying diseases, or steroid use. Significantly more patients diagnosed by sputum culture than bronchial lavage culture had a positive sputum smear for acid-fast bacilli (79.5% vs. 0.0%, respectively; p < 0.001) and any symptoms (75.3% vs. 46.2%, respectively; p = 0.0059). No significant differences were found in the prevalence of each computed tomography finding, including nodules, air-space disease, bronchiectasis, and cavities. However, more patients diagnosed by sputum culture than bronchial lavage culture had abnormalities in the left upper division (48.7% vs. 13.3%, respectively; p = 0.017) and higher numbers of affected lobes (4.3 ± 1.4 vs. 3.3 ± 1.6, respectively; p = 0.034). If patients suspected of having pulmonary MAC disease have a negative sputum smear, no symptoms, no abnormal findings in the left upper division, or fewer affected lobes on computed tomography, bronchoscopy might be needed for the diagnosis.

A 68-year-old man visited an emergency department complaining of dyspnea. He was diagnosed to have Legionella pneumonia with multiple organ failure. Although his multiple organ failure improved, he suffered from persistent abdominal pain and diarrhea with continuous minor bleeding. Colonoscopy revealed a longitudinal ulcer of the rectum, below the peritoneal reflection. He was diagnosed with cytomegalovirus (CMV) colitis. Antiviral therapy with ganciclovir was initiated. He finally underwent a colostomy after a bowel stricture caused an intestinal outlet obstruction, which made oral intake impossible. Based on the present case, we believe that CMV colitis must be considered as one of the differential diagnoses when critically ill patients develop continuous diarrhea and abdominal pain.

Overactive bladder (OAB) and benign prostatic hyperplasia (BPH) are highly prevalent conditions that place a large burden on the United States (US) health care system. We sought to analyze patterns of prescription medication usage for incident OAB in men and women, and for incident BPH in men using US health insurance claims data. This study used Truven Health MarketScan® Commercial and Medicare Supplemental Research databases. The data were pooled from diverse points of care. BPH subjects included men age 18+ with the first and last two diagnoses of BPH ≥30 days apart and no BPH diagnosis for 1 year prior. OAB subjects included men and women age 18+, who were diagnosed similarly with incident OAB. The type of medication, medication continuation (persistence), and switching to a different medication were analyzed through September 30, 2013. Medication persistence was much higher overall for BPH than OAB (56% vs 34%, respectively, P < 0.0001), and was highest among men with BPH age 65+ (62%). Patients age 18-64 were less likely to continue medication than older adults (age 65+) for both BPH and OAB. A 9.4% of patients in the OAB cohort and 6.9% of men with BPH switched from one medication to another. Persistence was higher with BPH than OAB medications overall, whereas switching rates were higher in the OAB group. The lower persistence of OAB medication may be due to less efficacy or tolerability. The possibility of under treatment of OAB also warrants future investigations. © 2017 Wiley Periodicals, Inc.

Among the intrahepatic bile ducts, the biliary system of the left medial sectional bile duct (B4) is known to have relatively complex patterns. The records of 500 patients who had been diagnosed as having hepato-pancreatico-biliary disease were retrospectively studied for anatomical biliary variations of the left liver with special reference to the drainage system of B4 using magnetic resonance images. The left hepatic duct was present in 494 patients (98.8%), whereas it was lacking in 6 patients (1.2%), and these patients exhibited the following B4 confluence patterns: B4 drained into the common hepatic duct in 2 patients (.4%), the right anterior sectional bile duct in 3 patients (.6%), and the right posterior sectional bile duct in 1 patient (.2%). The left hepatic duct was absent more frequently in patients with portal venous variations than in patients with a common branching pattern (8.2% vs .4%, P = .0011). The presently reported data are useful for obtaining a better understanding of the surgical anatomy of the biliary system of the left liver. Copyright © 2015 Elsevier Inc. All rights reserved.

Little is known about the mechanisms underlying the transition from paroxysmal to persistent atrial fibrillation (AF). In an ovine model of long-standing persistent AF we tested the hypothesis that the rate of electric and structural remodeling, assessed by dominant frequency (DF) changes, determines the time at which AF becomes persistent. Self-sustained AF was induced by atrial tachypacing. Seven sheep were euthanized 11.5±2.3 days after the transition to persistent AF and without reversal to sinus rhythm; 7 sheep were euthanized after 341.3±16.7 days of long-standing persistent AF. Seven sham-operated animals were in sinus rhythm for 1 year. DF was monitored continuously in each group. Real-time polymerase chain reaction, Western blotting, patch clamping, and histological analyses were used to determine the changes in functional ion channel expression and structural remodeling. Atrial dilatation, mitral valve regurgitation, myocyte hypertrophy, and atrial fibrosis occurred progressively and became statistically significant after the transition to persistent AF, with no evidence for left ventricular dysfunction. DF increased progressively during the paroxysmal-to-persistent AF transition and stabilized when AF became persistent. Importantly, the rate of DF increase correlated strongly with the time to persistent AF. Significant action potential duration abbreviation, secondary to functional ion channel protein expression changes (CaV1.2, NaV1.5, and KV4.2 decrease; Kir2.3 increase), was already present at the transition and persisted for 1 year of follow up. In the sheep model of long-standing persistent AF, the rate of DF increase predicts the time at which AF stabilizes and becomes persistent, reflecting changes in action potential duration and densities of sodium, L-type calcium, and inward rectifier currents.

Abstract Background: The measurements used in diagnosing biomechanical pathologies vary greatly. The aim of this study was to determine the concordance between Clarke's angle and Chippaux-Smirak index, and to determine the validity of Clarke's angle using the Chippaux-Smirak index as a reference. Methods: Observational study in a random population sample (n= 1,002) in A Coruña (Spain). After informed patient consent and ethical review approval, a study was conducted of anthropometric variables, Charlson comorbidity score, and podiatric examination (Clarke's angle and Chippaux-Smirak index). Descriptive analysis and multivariate logistic regression were performed. Results: The prevalence of flat feet, using a podoscope, was 19.0% for the left foot and 18.9% for the right foot, increasing with age. The prevalence of flat feet according to the Chippaux-Smirak index or Clarke's angle increases significantly, reaching 62.0% and 29.7% respectively. The concordance (kappa I) between the indices according to age groups varied between 0.25-0.33 (left foot) and 0.21-0.30 (right foot). The intraclass correlation coefficient (ICC) between the Chippaux-Smirak index and Clarke's angle was -0.445 (left foot) and -0.424 (right foot). After adjusting for age, body mass index (BMI), comorbidity score and gender, the only variable with an independent effect to predict discordance was the BMI (OR= 0.969; 95% CI: 0.940-0.998). Conclusion: There is little concordance between the indices studied for the purpose of diagnosing foot arch pathologies. In turn, Clarke's angle has a limited sensitivity in diagnosing flat feet, using the Chippaux-Smirak index as a reference. This discordance decreases with higher BMI values. PMID:28559643

Cardiac involvement in sarcoidosis is reported in up to 30% of patients. Left ventricular involvement demonstrated by contrast-enhanced cardiac magnetic resonance has been well validated. We sought to determine the prevalence and distribution of right ventricular late gadolinium enhancement in patients diagnosed with pulmonary sarcoidosis. We prospectively evaluated 87 patients diagnosed with pulmonary sarcoidosis with contrast-enhanced cardiac magnetic resonance for right ventricular involvement. Pulmonary artery pressures were non-invasively evaluated with Doppler echocardiography. Patient characteristics were compared between the groups with and without right ventricular involvement, and right ventricular enhancement was correlated with pulmonary hypertension, ventricular mass, volume, and systolic function. Left ventricular late gadolinium enhancement was demonstrated in 30 patients (34%). Fourteen patients (16%) had right ventricular late gadolinium enhancement, with sole right ventricular enhancement in only two patients. The pattern of right ventricular enhancement consisted of right ventricular outflow tract enhancement in 1 patient, free wall enhancement in 8 patients, ventricular insertion point enhancement in 10 patients, and enhancement of the right side of the interventricular septum in 11 patients. Pulmonary arterial hypertension correlated with the presence of right ventricular enhancement (P < 0.001). Right ventricular enhancement correlated with systolic ventricular dysfunction (P < 0.001), hypertrophy (P = 0.001), and dilation (P < 0.001). Right ventricular enhancement was present in 16% of patients diagnosed with pulmonary sarcoidosis and in 48% of patients with left ventricular enhancement. The presence of right ventricular enhancement correlated with pulmonary arterial hypertension, right ventricular systolic dysfunction, hypertrophy, and dilation. © 2017 The Authors.

The measurements used in diagnosing biomechanical pathologies vary greatly. The aim of this study was to determine the concordance between Clarke's angle and Chippaux-Smirak index, and to determine the validity of Clarke's angle using the Chippaux-Smirak index as a reference. Observational study in a random population sample (n= 1,002) in A Coruña (Spain). After informed patient consent and ethical review approval, a study was conducted of anthropometric variables, Charlson comorbidity score, and podiatric examination (Clarke's angle and Chippaux-Smirak index). Descriptive analysis and multivariate logistic regression were performed. The prevalence of flat feet, using a podoscope, was 19.0% for the left foot and 18.9% for the right foot, increasing with age. The prevalence of flat feet according to the Chippaux-Smirak index or Clarke's angle increases significantly, reaching 62.0% and 29.7% respectively. The concordance (kappa I) between the indices according to age groups varied between 0.25-0.33 (left foot) and 0.21-0.30 (right foot). The intraclass correlation coefficient (ICC) between the Chippaux-Smirak index and Clarke's angle was -0.445 (left foot) and -0.424 (right foot).

There is little concordance between the indices studied for the purpose of diagnosing foot arch pathologies. In turn, Clarke's angle has a limited sensitivity in diagnosing flat feet, using the Chippaux-Smirak index as a reference. This discordance decreases with higher BMI values.

Bilateral Renal Anastomosing Hemangiomas: A Tale of Two Kidneys

PubMed Central

Abboudi, Hamid; Tschobotko, Benjamin; Carr, Christopher

2017-01-01

Abstract Background: Renal anastomosing hemangioma (RAH) is an extremely rare benign vascular tumor first described in 2009. Making this diagnosis is fraught with challenges. Radiologically they share features consistent with renal cell carcinomas (RCCs). Their vascular nature poses risks if considering preoperative biopsy and histologically they share characteristics akin to angiosarcomas. The few reports published in the literature suggest presentation with hematuria, flank pain, and polycythemia although the majority are diagnosed at postnephrectomy histologic examination. This case represents the first metachronous RAH in the literature, and is the first RAH presenting with severe hemorrhage. Case Presentation: A 62-year-old woman of Albanian heritage presented to urology with visible hematuria and positive urine cytology. Three years before this presentation, she had undergone an elective radical right-sided nephrectomy for a suspected RCC detected on magnetic resonance imaging, which proved to be an RAH after postoperative histologic examination of the specimen. The patient was investigated with cystoscopy and ureteroscopy for this new hematuria presentation, both of which were unremarkable. Fourteen hours post ureteroscopy, the patient became severely hypotensive and developed acute kidney injury. A CT scan indicated a large left-sided renal subcapsular and retroperitoneal hematoma that was actively bleeding. The patient was hemodynamically unstable and, therefore, required an emergency open left-sided nephrectomy, rendering her anephric and dialysis dependent. Postoperative histologic examination proved that the left kidney also contained an RAH. Conclusion: The anastomosing hemangioma is an important subtype to differentiate from angiosarcoma before and after a nephrectomy. Urologists should carefully consider invasive tests in patients with previously diagnosed vascular lesions as there may be an increased risk of bleeding. Patients with a previously diagnosed anastomosing hemangioma may require surveillance of the contralateral kidney. PMID:29279869

Multimodal ultrasonographic assessment of leiomyosarcoma of the femoral vein in a patient misdiagnosed as having deep vein thrombosis

PubMed Central

Zhang, Mei; Yan, Feng; Huang, Bin; Wu, Zhoupeng; Wen, Xiaorong

2017-01-01

Abstract Rationale: Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT). Moreover, virtually no studies have described the ultrasonographic features of LMS of the vein in detail. Patient concerns: We present a case of a 55-year-old woman with LMS of the left femoral vein that was misdiagnosed as having deep vein thrombosis (DVT) on initial ultrasonographic examination. The patient began to experience edema and pain in her left leg seven months previously. She was diagnosed as having DVT on initial ultrasonographic examination, but the DVT treatment that she had received for 7 months failed to improve the status of her left lower limb. Diagnoses: She subsequently underwent re-examination by means of a multimodal ultrasonographic imaging approach (regular B-mode imaging, color Doppler imaging, pulsed-wave Doppler imaging, contrast-enhanced ultrasonography), which confirmed a diagnosis of LMS. Interventions: This patient was treated successfully with surgery. Outcomes: This case demonstrates that use of multiple ultrasonographic imaging techniques can be helpful to diagnose LMS accurately. Detection of vasculature in a dilated vein filled with a heterogeneous hypoechoic substance on ultrasonography is a sign of a tumor. Lessons: The pitfall of misdiagnosing this tumor as DVT is a useful reminder. PMID:29145269

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart disease usually diagnosed during the first months of life. Without surgical treatment, ALCAPA carries a high mortality risk, and disease presentation in adulthood is rare. We describe the diagnosis and management of patients presenting with ALCAPA in adulthood. This multicenter French nationwide retrospective study included adult patients diagnosed from 1980 to 2014. Eleven adult patients (mean age: 38 ± 17 years) were analyzed. All patients were symptomatic, presenting with chest pain, palpitations, heart failure, or syncope. Electrocardiogram was abnormal in 8 (73%) patients. Echocardiogram showed a mildly depressed left ventricular ejection fraction of 50 ± 13%, kinetic abnormalities in 5 (45%) patients, and significant mitral regurgitation in 8 (73%) patients. Coronary angiography was performed in 10 (91%) patients and confirmed the diagnosis. Computerized tomography scan, magnetic resonance imaging, and myocardial scintigraphy were performed when deemed necessary. Ten patients underwent reconstructive surgery, but 1 patient was not operated because of age. Four patients experienced postoperative complications including cardiogenic shock, heart failure, renal failure, or additional surgery. After a median follow-up of 2.5 years, all 10 operated patients were alive and asymptomatic, and the nonoperated patient had died at the age of 70 from syncope related to ventricular tachycardia. ALCAPA may be diagnosed in adults. Although complications may occur postoperatively, long-term outcome is favorable in adult patients undergoing surgical correction. Surgery should be discussed as first-line therapy in adults with ALCAPA. Copyright © 2017 Elsevier Inc. All rights reserved.

Adult readers with developmental phonological dyslexia exhibit significant difficulty comparing pseudowords and pure tones in auditory working memory (AWM). This suggests deficient AWM skills for adults diagnosed with dyslexia. Despite behavioral differences, it is unknown whether neural substrates of AWM differ between adults diagnosed with dyslexia and normal readers. Prior neuroimaging of adults diagnosed with dyslexia and normal readers, and post-mortem findings of neural structural anomalies in adults diagnosed with dyslexia support the hypothesis of atypical neural activity in temporoparietal and inferior frontal regions during AWM tasks in adults diagnosed with dyslexia. We used fMRI during two binaural AWM tasks (pseudowords or pure tones comparisons) in adults diagnosed with dyslexia (n = 11) and normal readers (n = 11). For both AWM tasks, adults diagnosed with dyslexia exhibited greater activity in left posterior superior temporal (BA 22) and inferior parietal regions (BA 40) than normal readers. Comparing neural activity between groups and between stimuli contrasts (pseudowords vs. tones), adults diagnosed with dyslexia showed greater primary auditory cortex activity (BA 42; tones > pseudowords) than normal readers. Thus, greater activity in primary auditory, posterior superior temporal, and inferior parietal cortices during linguistic and non-linguistic AWM tasks for adults diagnosed with dyslexia compared to normal readers indicate differences in neural substrates of AWM comparison tasks.

A 62-year-old man was admitted with generalised abdominal pain, constipation and vomiting. His abdomen was markedly distended and tender on general examination with signs of local peritonism in the left iliac fossa. He was initially diagnosed with likely acute diverticulitis and treated conservatively. A CT scan the next day showed fluid filled, dilated small bowel loops consistent with small bowel obstruction and there was a suggestion of an abscess in the left iliac fossa region. An urgent laparotomy was performed, which identified a perforated Meckel diverticulum. PMID:22479299

The presented case was a 3-year-old boy diagnosed with asplenia (SLL), double outlet right ventricle, pulmonary stenosis, atrioventricular septal defect, hypoplastic left ventricle and partial anomalous pulmonary venous connection to the superior vena cava. Partial anomalous pulmonary venous connection was repaired by translocation of pulmonary artery to avoid pulmonary venous obstruction when Glenn anastomosis was performed. Total cavo-pulmonary connection was established by re-routing the inferior vena cava to pulmonary artery using the atrial septal remnant and the left atrium free wall flap.

Pheochromocytoma is a tumor originating from chromaffin tissue. It commonly presents with symptoms and signs of catecholamine excess, such as hypertension, tachycardia, headache and sweating. Cardiovascular manifestations include catecholamine-induced cardiomyopathy, which may present as severe left ventricular dysfunction and congestive heart failure. We report a case of pheochromocytoma which was diagnosed following investigation of dilated cardiomyopathy. We highlight the dramatic symptomatic improvement and reversal of cardiomyopathy, with recovery of left ventricular function after treatment. Copyright © 2013 Sociedade Portuguesa de Cardiologia.

Cardiac myxomas are rare tumors. Esophageal adenocarcinomas are common tumors of the gastrointestinal tract. Simultaneous occurrence of these tumors has not been reported. A 52-year-old gentleman presented to our hospital with dysphagia and was diagnosed with esophageal adenocarcinoma. Routine echocardiography discovered a cardiac tumor in the left atrium. The cardiac tumor was surgically removed and biopsy confirmed a myxoma. We removed the cardiac tumor as the first step and then initiated neoadjuvant chemotherapy. It is ideal to constitute a multidisciplinary team to decide on the course of treatment in such cases.

Noncompaction cardiomyopathy is a rare phenotype of cardiomyopathy associated with severe cardiac arrhythmia and thromboembolic complications. A 55-year-old woman presented with frank pulmonary edema and received a diagnosis of noncompaction cardiomyopathy. Left ventricular noncompaction cardiomyopathy is increasingly being diagnosed because of advances in imaging modalities. It is important to differentiate this new phenotype of cardiomyopathy from others because its diagnosis, management, and prognosis differ. We reviewed the literature and summarized the diagnostic criteria, associated complications, initial and long-term management, and the recommendation for family screening.

To evaluate the effect of rescue transesophageal echocardiography (TEE) on the management of trauma patients, we reviewed imaging and charts of unstable trauma patients at a level I trauma center. Critical rescue TEE findings included acute right ventricular failure, stress cardiomyopathy, type B aortic dissection, mediastinal air, and dynamic left ventricular outflow tract obstruction. Left ventricular filling was classified as low (underfilled) in 57% of all cases. Rescue TEE revealed a variety of new diagnoses and led to a change in resuscitation strategy about half of the time.

Squamous cell carcinoma (SCC) is the most common malignant neoplasm of the oral cavity. The clinical features of gingival SCC include alveolar bone loss and erythematous lesion. Therefore, gingival SCC sometimes presents as advanced periodontitis. This case report describes a patient diagnosed with gingival SCC after the extraction of molars presenting as being affected by localized severe periodontitis. The patient was a 61-year-old man whose chief complaint was pain in the left maxillary area. Clinical and radiographic examinations revealed common findings of a periodontal abscess on the left maxillary first and second molars. These teeth were extracted based on a diagnosis of a periodontal abscess. Three months later, a rapidly growing exophytic soft tissue mass was observed, and a biopsy of the mass was performed. According to the biopsy, the final diagnosis was a well-differentiated SCC. The patient was treated with a partial maxillectomy of the left maxilla and split-thickness skin graft. Two years after treatment, the patient remained free of recurrence. Gingival SCC is quite different from other forms of SCC, mimicking localized periodontal disease. Therefore, it can be misdiagnosed as localized periodontal disease and is generally discovered after extracting teeth. Therefore, clinicians must diagnose these lesions carefully and follow up with the patient after tooth extraction.

Missed appendicitis after self-induced abortion.

Female lower abdominal pain poses diagnostic difficulties for clinicians, especially when little more than the history and physical examination are available. A girl presented with constant lower abdominal pain after taking misoprostol for pregnancy termination. She was eventually referred to a rural District Hospital, where a laparotomy demonstrated acute appendicitis. After treating herself for a self-diagnosed pregnancy with illegally provided misoprostol, this patient presented with persistent lower abdominal pain. The differential diagnosis included ectopic pregnancy and all other causes of female abdominal pain. Yet diagnosing two diseases in the same anatomical area at the same time contradicts diagnostic parsimony. System problems in resource-poor areas can limit access to healthcare services and encourage dispensing potentially dangerous medications without clinicians' authorization. It is dangerous to rely on patients' self-diagnoses while neglecting other diagnoses. More than one diagnosis may be needed to explain temporally and anatomically related symptoms.

We report the case of a 61-year-old woman with persistent thyrotoxicosis for 7 years despite low thyroidal radioiodine uptake and methimazole treatment. Her initial I whole-body scan (WBS) was read as negative. Upon evaluation in our institution, she remained hyperthyroid after discontinuation of methimazole. Repeat WBS with SPECT/CT revealed low 24-hour thyroidal uptake (RAIU = 2%) and intensely focal radioiodine uptake in a large heterogeneous left pelvic mass, consistent with left adnexal struma ovarii. Resection of this mass confirmed benign struma ovarii. This case illustrates the advantage of fusion SPECT/CT imaging with planar I-WBS for diagnosis of extrathyroidal thyrotoxicosis.

Neural Indices of Semantic Processing in Early Childhood Distinguish Eventual Stuttering Persistence and Recovery.

PubMed

Kreidler, Kathryn; Hampton Wray, Amanda; Usler, Evan; Weber, Christine

2017-11-09

Maturation of neural processes for language may lag in some children who stutter (CWS), and event-related potentials (ERPs) distinguish CWS who have recovered from those who have persisted. The current study explores whether ERPs indexing semantic processing may distinguish children who will eventually persist in stuttering (CWS-ePersisted) from those who will recover from stuttering (CWS-eRecovered). Fifty-six 5-year-old children with normal receptive language listened to naturally spoken sentences in a story context. ERP components elicited for semantic processing (N400, late positive component [LPC]) were compared for CWS-ePersisted, CWS-eRecovered, and children who do not stutter (CWNS). The N400 elicited by semantic violations had a more focal scalp distribution (left lateralized and less anterior) in the CWS-eRecovered compared with CWS-ePersisted. Although the LPC elicited in CWS-eRecovered and CWNS did not differ, the LPC elicited in the CWS-ePersisted was smaller in amplitude compared with that in CWNS. ERPs elicited in 5-year-old CWS-eRecovered compared with CWS-ePersisted suggest that future recovery from stuttering may be associated with earlier maturation of semantic processes in the preschool years. Subtle differences in ERP indices offer a window into neural maturation processes for language and may help distinguish the course of stuttering development.

A 16-year-old male grey-cheeked parakeet (Brotogeris pyrrhopterus) was presented for dyspnea and decreased activity. The bird's diet was primarily table food, with a large proportion of animal products. Radiographs revealed a linear mineralized structure in the plane of the aorta and an enlarged hepatocardiac silhouette. Left atrial and left ventricular enlargement and a left ventricular systolic dysfunction were diagnosed by echocardiography. The bird's condition progressively declined, and it died 5 days after presentation. A postmortem examination revealed marked atherosclerosis of the aorta, great vessels of the heart, and coronary arteries with myocardial degeneration, pulmonary congestion, and ascites. Little is known about the risk factors of atherosclerosis in psittacine birds, and dietary influence, if any, is not understood.

Splenic abcess is an uncommon complication for cancer treatment. It occurs more frequently in immunocompromised patients. They are characterized by high mortality. The classic triad (fever, pain of the left hypochondrium, and sensitive mass left) is only present in one-third of cases the clinical spectrum ranging from no symptoms to events such as fever, nausea, vomiting, weight loss, abdominal pain left, splenomegaly. Treatment options are limited, but must be discussed and adapted to the patient profile. We report the case of a 62-year-old Arabic male, diagnosed with metastatic lung adenocarcinoma, who, after several cycles of chemotherapy, presented symptoms and signs of splenic abcess. Splenic abcess is rare situation, which must be actively researched, to have access to an optimal therapeutic approach.

The authors present a case of a 67-year-old male patient, who previously had been diagnosed with a malignant liver tumor localized in segment II. He underwent bisegmentectomy (II and III) and partial IV segmentectomy. After the primary surgery jaundice developed, the level of bilirubin increased and after several imaging modalities reoperation was indicated. During the surgery a rare bile duct anatomy variant was found. The right hepatic duct joined the left duct in the parenchyma of the left lobe, and was ligated at the resection. As the liver hilum was not explored, the absence of the right duct was not discovered. Reconstruction of the biliary system was accomplished by a Roux-en-Y loop.

A boy, prenatally diagnosed as hypoplastic left heart syndrome (HLHS) with intact atrial septum (IAS) was successfully treated by hybrid procedures. He underwent emergent catheter atrial septostomy and stent insertion in the atrial septum on Day 1 and then underwent bilateral pulmonary artery banding, ductal stent insertion, modified Norwood operation, bidirectional Glenn's operation and finally Fontan type operation at 2 years of age. Considering the presence of decompression pathway from the left atrium in HLHS with IAS, we should organize a treatment team for collaborative work and plan an appropriate treatment strategy before delivery. Although his clinical course has been uneventful until now, closer medical observation is warranted because he may have coexisting pulmonary disease.

Atypical findings in a patient with a renal milky stone including a cake of stone.

A 54-year-old woman was admitted to our department with the diagnosis of a renal calculus. She exhibited dull left flank pain. A plain film revealed a round opaque calcific density in the left kidney in the supine and the upright position. There was no connection between the calcification and the renal collecting system by retrograde pyelography. Computed tomography in the supine position showed a rounded calcification in the left renal parenchyma without a semilunar configuration. She was diagnosed with left renal calyceal diverticula calculi. She underwent a surgical intervention which found a renal milky stone including a 10-mm. diameter stone. The examination of the fluid and the stone material disclosed three components: calcium phosphate, calcium oxalate and calcium carbonate. The present case is interesting because its characteristics differ from the common features of renal milky stone.

A 69-year-old male had catheter-based ablation for atrial fibrillation. He was admitted with high fever and had neurological disorder; he was diagnosed with atrioesophageal fistula by CT scan. Intraoperative findings showed that the fistula existed adjacent to the left lower pulmonary vein with a vegetation. The esophageal fistula was repaired, and the left atrial fistula was closed. A nasogastric tube tip was placed in the esophagus for decompression and advanced into the stomach for nutritional support. After vomiting, the patient showed loss of consciousness and left hemiplegia. CT scan revealed a micro-air embolism to the brain. The nasogastric tube tip was pulled back into the esophagus. Gastrointestinal fiberscopy showed a pinhole at the fistula, and a percutaneous endoscopic gastrostomy was made. After conservative treatment, the esophageal fistula was closed and mediastinitis was improved. He was discharged with a little neurological deficit.

Clinical, echocardiographic, and Doppler imaging characteristics of mitral valve stenosis in two dogs.

PubMed

Fox, P R; Miller, M W; Liu, S K

1992-11-15

Mitral stenosis was diagnosed noninvasively by echocardiography and Doppler imaging in 2 Bull Terriers. Two-dimensional echocardiography revealed severe atrial and moderate left ventricular dilatation; severely reduced mitral valve opening excursion; doming of the cranial mitral valve leaflet into the left ventricle during diastole; thickened, nodular cranial mitral valve leaflets; and reduced mitral valve orifice. M-mode echocardiographic findings additionally indicated greatly diminished mitral valve E to F slope and abnormal caudal mitral valve leaflet motion. Color flow Doppler imaging revealed bright bursts of color with aliasing originating from the stenotic mitral valve orifice, extending into the left atrium during systole, and into the left atrium during diastole. Spectral Doppler recordings revealed transvalvular mitral valve gradients and prolonged pressure half-times. Necropsy performed on 1 dog revealed extremely thickened, nodular, and stiff mitral valves with short, thickened, and fused chordae tendineae. The diagnosis of mitral valve stenosis was easily facilitated with diagnostic ultrasonography.

Her best corrected visual acuity for the concerned eye was no light perception. Also, a relative afferent pupillary defect was detected in this eye. The left fundus exhibited widespread retinal whitening with visible emboli in several retinal arterioles. Diffusion-weighted magnetic resonance imaging of the brain showed a hyperintense lesion at the left insular cortex. Therefore, we diagnosed ophthalmic artery obstruction and left middle cerebral artery infarction due to fat emboli. The patient was managed with immediate ocular massage, carbon dioxide, and oxygen therapy. Following treatment, dysarthria improved considerably but there was no improvement in visual acuity.

Synchronous bilateral breast cancer is extremely rare in men and has not, up to date, been reported in Korea. A 54-year-old man presented with a palpable mass in the right breast. The right nipple was retracted and bilateral axillary accessory breasts and nipples were present. On physical examination, a 2 cm-sized mass was palpated directly under the right nipple, and, with squeezing, bloody discharge developed in a single duct of the left nipple. There was no palpable mass in the left breast, and axillary lymph nodes were not palpable. Physical examination of external genitalia revealed a unilateral undescended testis on the left side. Synchronous bilateral breast cancer was diagnosed using mammography, ultrasonography, and core-needle biopsy. Histopathological examination revealed invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast. Bilateral total mastectomy, sentinel lymph node biopsy, and excision of accessory breasts in the axilla were performed. PMID:22807945

: This study examines risk factors for persistent cervical intraepithelial neoplasia (CIN) and examines whether human papillomavirus (HPV) testing predicts persistent lesions. : Women with histologically diagnosed CIN 1 or CIN 2 (n = 206) were followed up every 3 months without treatment. Human papillomavirus genotyping, plasma levels of ascorbic acid, and red blood cell folate levels were obtained. Cervical biopsy at 12 months determined the presence of CIN. Relative risk (RR) was estimated by log-linked binomial regression models. : At 12 months, 70% of CIN 1 versus 54% of CIN 2 lesions spontaneously regressed (p < .001). Levels of folate or ascorbic acid were not associated with persistent CIN at 12 months. Compared with HPV-negative women, those with multiple HPV types (RRs ranged from 1.68 to 2.17 at each follow-up visit) or high-risk types (RRs range = 1.74-2.09) were at increased risk for persistent CIN; women with HPV-16/18 had the highest risk (RRs range = 1.91-2.21). Persistent infection with a high-risk type was also associated with persistent CIN (RRs range = 1.50-2.35). Typing for high-risk HPVs at 6 months only had a sensitivity of 46% in predicting persistence of any lesions at 12 months. : Spontaneous regression of CIN 1 and 2 occurs frequently within 12 months. Human papillomavirus infection is the major risk factor for persistent CIN. However, HPV testing cannot reliably predict persistence of any lesion.

In aortic insufficiency (AI) the inhibition of the stimulated Renin-Angiotensin-System (RAS) by Captopril (C) reduced afterload and leads consequently to a diminished regurgitation fraction (RF). In 17 patients (pts) with pure severe AI RF, left ventricular ejection fraction (LVEFE) and heart rate were determined before (1) and 1 hr after (2) administration of 25 mg of C.Long term dosis was 3 x 25 mg of C and follow up time was 3-11 months (medium:6). The values were determined by gated radionuclide ventriculography using red blood cells labeled in vivo with 15 mCi Tc-99mROI's were selected over both ventricles in enddiastolicmore » and endsystolic frames. Ventricular boundaries were defined by a fourier phase image overlay. RF was calculated by the background corrected count rate ratio of left and right ventricular ROI. Systolic and diastolic blood pressure (BPs,BPd), plasma levels of angiotensin I,II(A1,A2) and the activity of angiotensin converting enzyme (ACE) were determined before and 1 hr after C administration. After C there is a decrease in RF which persists in the long term follow period in up to to now 8 pts. The authors conclude: inhibition of ACE reduces significantly aortic regurgitation in patients with AI and has thus a beneficial effect on left ventricular performance. This effect persists in long term treatment and therefore seems beneficial to delay the point of operation.« less

Cardiac sarcoma is a very rare neoplasm and is difficult to diagnose. The case of a 51-year-old man with a left atrial tumour, locally recurrent three months after its surgical removal, is presented. Computed tomography showed metastatic spread to the lung parenchyma. On revised histology, the mass extirpated was a sarcoma. Because of the metastatic spread, further therapy was symptomatic only; the patient died 15 months after the first manifestation of his problems. Immunohistochemical staining confirmed cardiac rhabdomyosarcoma with metastatic spread to the lungs. Difficulty in diagnosing and treating cardiac tumours is discussed. PMID:20428274

Common adverse events in patients supported with Continuous-flow left ventricular assist devices (CF-LVAD) include infections and cerebrovascular accidents (CVA). Some studies have suggested a possible association between blood stream infection (BSI) and CVA. Medical records of patients who received Heartmate II (HMII) CF-LVADs in 2008-2012 at a single center were reviewed. CVA was categorized as either hemorrhagic (HCVA) or ischemic (ICVA). BSI was divided into persistent (pBSI) and nonpersistent (non-pBSI). pBSI was defined as BSI with the same organism on repeated blood culture >72 hours from initial blood culture despite antibiotics. Univariate and multivariate analyses were performed to determine predictors. A total of 149 patients had HMII implanted; 76% were male, and the overall mean age was 55.4 ± 13 years. There were a total of 19 (13%) patients who had CVA (7 HCVA and 12 ICVA) at a median of 295 days (range 5-1,096 days) after implantation. There were a total of 28 (19%) patients with pBSI and 17 (11%) patients with non-pBSI. Patients with pBSI had a trend toward greater BMI (31 kg/m(2) vs 27 kg/m(2); P = .09), and longer duration of support (1,019 d vs 371 d; P < .001) compared with those with non-pBSI. Persistent BSI was associated with an increased risk of mortality and with all-cause CVA on multivariate analysis (odds ratio [OR] 5.97; P = .003) as well as persistent Pseudomonas aeruginosa infection (OR 4.54; P = .048). Persistent BSI is not uncommon in patients supported by CF-LVAD and is highly associated with all-cause CVA and increased all-cause mortality. Copyright © 2015 Elsevier Inc. All rights reserved.

A 3-year-old boy child died at home. The circumstances of death appeared unclear to the police investigators and a medicolegal autopsy was carried out. External examination revealed diffuse ecchymoses of varying colours. Postmortem imaging using plain X-rays and multislice computed tomography (MSCT) was performed prior to autopsy and pathological study. These investigations revealed fractures at the posterior arch of the ninth left rib. No cerebral and pericerebral traumatic lesions were diagnosed. In the abdomen, haemoperitoneum and pneumoperitoneum secondary to duodenal perforation and liver laceration were observed. At autopsy, a complete pancreatic fracture and duodenal transection were noted, accounting for the MSCT appearance. Furthermore, autopsy revealed the presence of bilateral intramuscular intercostal haemorrhages and a fracture of the eighth left rib at its posterior arch. This case report illustrates the valuable assistance rendered by MSCT as well as its limitations in diagnosing abuse when a child dies in unclear circumstances. Copyright © 2010 Elsevier Ireland Ltd.

2016-01-01

Riedel's thyroiditis is a rare type of chronic thyroiditis, associated with fibroinflammatory process and invasion into surrounding tissues, leading to compressive symptoms. A 45-year-old man had a left thyroid mass, presenting with hypotension and bradycardia many times. He was diagnosed with vasovagal reflex caused by cervical vessel compression due to a thyroid lesion. We performed the emergency operation, and most of the left thyroid was removed to relieve the compression on cervical vessels. The result of pathology proved to be Riedel's thyroiditis. The vasovagal reflex did not occur any more during the 28-month follow up, except on the 3(rd) day after the surgery. Six months after the thyroidectomy, the patient was found to have retroperitoneal fibrosis, diagnosed by biopsy during a laparotomy for biliary disease. Riedel's thyroiditis can lead to a vasovagal episode and might not be a primary thyroid disease but rather a manifestation of the systemic disorder, multifocal fibrosclerosis. Copyright © 2013.

Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a case of perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-up for breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid cancer. Therefore, laparoscopic distal gastrectomy with lymph node dissection and left thyroidectomy were performed. On the basis of the pathologic findings of the surgical specimens, the patient was diagnosed to have papillary thyroid microcarcinoma with perigastric lymph node metastasis and early gastric cancer with mucosal invasion. Finally, on the basis of immunohistochemical staining with galectin-3, the diagnosis of perigastric lymph node metastasis from PTC was made. When a patient has multiple primary malignancies with lymph node metastasis, careful pathologic examination of the surgical specimen is necessary; immunohistochemical staining may be helpful in determining the primary origin of lymph node metastasis.

The etiology of internal root resorption is not fully understandable, trauma and chronic pulpitis are considered the main risk factors. Usually the process is asymptomatic and diagnosed upon routine radiographic examination. This case report presents a rapid progression of internal resorption related directly to traumatic injury. A 16-year-old female arrived at the emergency room after a mild extrusion of the mandibular incisors. The initial treatment included repositioning and splinting of the teeth. Radiographs performed at repositioning and splinting demonstrated normal configuration of the incisor's roots. Ten months later progressive internal resorption of the left mandibular first incisor was diagnosed. While treating this tooth similar process was detected in the right mandibular second incisor and in the mandibular left second incisor. The lower right first incisor reacted inconsistently to vitality test. As a result of the severe and rapidly progressive nature of the process, root canal treatments were performed in all lower incisors. The follow-up radiographs demonstrate arrest of the internal resorption process.

To describe a rare branch retinal vein occlusion (BRVO) followed by central retinal artery occlusion (CRAO) in a patient with Churg-Strauss syndrome (CSS). A 55-year-old man with a not yet diagnosed CSS developed a BRVO in the left eye and 1 year later a CRAO with painless and acute vision loss in the same eye. Medical history included bronchial asthma, history of allergy, eosinophilic pneumonia, bilateral pleuric and pericardial effusion, hypereosinophilia, and purpuric vasculitis. CRAO in the left eye was diagnosed by retinal whitening and a cherry red spot with coexisting old BRVO evidenced by previous laser photocoagulation. Corticosteroids and cyclophosphamide therapy improved his general condition but no visual recovery occurred. BRVO and CRAO can occur in the same eye in CSS. In the presence of systemic signs or symptoms, it is important to rule out systemic vasculitis in order to start appropriate immune-modulatory treatment thereby avoiding unnecessary mortality.

The Role of Left Occipitotemporal Cortex in Reading: Reconciling Stimulus, Task, and Lexicality Effects

Although the left posterior occipitotemporal sulcus (pOTS) has been called a visual word form area, debate persists over the selectivity of this region for reading relative to general nonorthographic visual object processing. We used high-resolution functional magnetic resonance imaging to study left pOTS responses to combinatorial orthographic and object shape information. Participants performed naming and visual discrimination tasks designed to encourage or suppress phonological encoding. During the naming task, all participants showed subregions within left pOTS that were more sensitive to combinatorial orthographic information than to object information. This difference disappeared, however, when phonological processing demands were removed. Responses were stronger to pseudowords than to words, but this effect also disappeared when phonological processing demands were removed. Subregions within the left pOTS are preferentially activated when visual input must be mapped to a phonological representation (i.e., a name) and particularly when component parts of the visual input must be mapped to corresponding phonological elements (consonant or vowel phonemes). Results indicate a specialized role for subregions within the left pOTS in the isomorphic mapping of familiar combinatorial visual patterns to phonological forms. This process distinguishes reading from picture naming and accounts for a wide range of previously reported stimulus and task effects in left pOTS. PMID:22505661

Objective. The risk of pulmonary embolism is well recognized as showing an increase in oncological patients. We report a case presenting with pulmonary embolism initially, which was then diagnosed with testicular cancer. Clinical Presentation and Intervention. A 25-year-old man was admitted to the emergency department with a complaint of dyspnoea. Thoracic tomography, lung ventilation/perfusion scintigraphy, and an increased D-dimer level revealed pulmonary embolism. For the aetiology of pulmonary embolism, a left orchiectomy was performed and the patient was diagnosed with a germinal cell tumour of the testicle. Conclusion. In this paper, we present a patient for whom pulmonary embolism was the initial presentation, and a germinal cell tumour was diagnosed later during the search for the aetiology. PMID:24383024

We present a case of a 24-year-old gentleman who presented with painless pan haematuria for 2 weeks. During the workup, he was diagnosed to have a retrocaval mass after a CT scan while cystoscopy revealed a polypoidal pulsating lesion in the left ureter. After surgical manipulation of the retrocaval mass, the blood pressure of the patient raised to 260/130 mm Hg. It was completely resected and diagnosed as extra-adrenal pheochromocytoma (paraganglioma) after histopathology. The lesion in the ureter was completely excised and fulgurated and diagnosed as an arteriovenous malformation. To the best of our knowledge, this is the first patient to be presented in the literature with this unusual combination.

We report a 42-year-old man with hereditary medullary thyroid cancer (multiple endocrine neoplasia, MEN2A/familial medullary thyroid carcinoma, FMTC), which was diagnosed at the time of tumor recurrence. He had a past history of a left thyroidectomy with neck dissection 7 years previously. A RET gene analysis revealed a point mutation (codon 618), and we diagnosed him as having hereditary medullary thyroid cancer. We resected the recurrent tumor in the right thyroid lobe together with performing a right lateral and central neck dissection. A RET gene analysis should be performed for patients with medullary thyroid cancer. When a RET gene mutation is present, a total thyroidectomy must be performed for the medullary thyroid cancer.

Objective: There are controversial reports about factors that affect recovery from stuttering. In the ‎present study, the effect of hand dominancy, fine motor and inhibition control on late ‎recovery from stuttering was investigated among a group of Kurdish-Persian children who ‎stuttered in Iran.‎ Method: Twenty-two Kurdish-Persian children aged 7-14 years who stuttered were followed for 6 ‎years. Based on the evaluation of three experienced speech therapists and parental judgments, ‎these children were classified into recovered or persistent groups. Data about fine motor ‎control of hand and inhibition control were obtained, using Purdue Pegboard and Victoria ‎Strop Color Word Tests, respectively. Risk factors including sex, age, and family history of ‎stuttering, handedness, inhibitory control and fine motor control of hand were compared ‎between the groups and modeled to predict recovery from stuttering using logistic regression.‎ Results: From the 22 participants, 5 (22.7%) recovered from stuttering. The recovered and persistent ‎groups did not show significant differences in the interference effect. By dividing the scores ‎of the Purdue Pegboard tests to the right and left hand, we created a new Handedness Index ‎‎(HI). HI was significantly higher in the recovered group. The score of right hand was higher ‎than the left in the recovered group, but no difference was found between the two hands in ‎the persistent group. Among the investigated risk factors, only HI could predict the recovery ‎from or persistency of stuttering with 94% sensitivity and 84% specificity.‎ Conclusion: Handedness Index can predict the recovery from stuttering significantly among children who ‎stutter.‎ PMID:27252769

A comparative study of cervical range of motion in asymptomatic persons and those with whiplash. To compare the primary and conjunct ranges of motion of the cervical spine in asymptomatic persons and those with persistent whiplash-associated disorders, and to investigate the ability of these measures of range of motion to discriminate between the groups. Evidence that range of motion is an effective indicator of physical impairment in the cervical spine is not conclusive. Few studies have evaluated the ability to discriminate between asymptomatic persons and those with whiplash on the basis of range of motion or compared three-dimensional in vivo measures of range of motion in asymptomatic persons and those with whiplash-associated disorders. The study participants were 89 asymptomatic volunteers (41 men, 48 women; mean age 39.2 years) and 114 patients with persistent whiplash-associated disorders (22 men, 93 women; mean age 37.2 years) referred to a whiplash research unit for assessment of their cervical region. Range of cervical motion was measured in three dimensions with a computerized, electromagnetic, motion-tracking device. The movements assessed were flexion, extension, left and right lateral flexion, and left and right rotation. Range of motion was reduced in all primary movements in patients with persistent whiplash-associated disorder. Sagittal plane movements were proportionally the most affected. On the basis of primary and conjunct range of motion, age, and gender, 90.3% of study participants could be correctly categorized as asymptomatic or as having whiplash (sensitivity 86.2%, specificity 95.3%). Range of motion was capable of discriminating between asymptomatic persons and those with persistent whiplash-associated disorders.

Ablation of persistent atrial fibrillation can be challenging, often involving not only pulmonary vein isolation (PVI) but also additional linear lesions and ablation of complex fractionated electrograms (CFE). We examined the impact of stepwise ablation on a human model of advanced atrial substrate of persistent atrial fibrillation in heart failure. In 30 patients with persistent atrial fibrillation and left ventricular ejection fraction ≤35%, high-density CFE maps were recorded biatrially at baseline, in the left atrium (LA) after PVI and linear lesions (roof and mitral isthmus), and biatrially after LA CFE ablation. Surface area of CFE (mean cycle length ≤120 ms) remote to PVI and linear lesions, defined as CFE area, was reduced after PVI (18.3±12.03 to 10.2±7.1 cm(2); P<0.001) and again after linear lesions (7.7±6.5 cm(2); P=0.006). Complete mitral isthmus block predicted greater CFE reduction (P=0.02). Right atrial CFE area was reduced by LA ablation, from 25.9±14.1 to 12.9±11.8 cm(2) (P<0.001). Estimated 1-year arrhythmia-free survival was 72% after a single procedure. Incomplete linear lesion block was an independent predictor of arrhythmia recurrence (hazard ratio, 4.69; 95% confidence interval, 1.05-21.06; P=0.04). Remote LA CFE area was progressively reduced following PVI and linear lesions, and LA ablation reduced right atrial CFE area. Reduction of CFE area at sites remote from ablation would suggest either regression of the advanced atrial substrate or that these CFE were functional phenomena. Nevertheless, in an advanced atrial fibrillation substrate, linear lesions after PVI diminished the target area for CFE ablation, and complete lesions resulted in a favorable clinical outcome.

Mortality, Disenrollment, and Spending Persistence in Medicaid and CHIP.

DeLia, Derek

Research on spending persistence has not focused on Medicaid and the Children's Health Insurance Program (Medicaid/CHIP), which includes a complex and growing population. The objective of the study was to describe patterns of expenditure persistence, mortality, and disenrollment among nondually eligible Medicaid/CHIP enrollees and identify factors predicting these outcomes. The study is based on New Jersey Medicaid/CHIP claims data from 2011 to 2014. Descriptive and multinomial regression methods were used to characterize persistently extreme spenders, defined as those appearing in the top 1% of statewide spending every year, according to demographics, Medicaid/CHIP eligibility, nursing facility residence, patient risk scores, and clinical diagnostic categories measured in 2011. Similar analyses were done for persistently high spenders (ie, always in the top 10% but not always top 1%) as well as decedents, disenrollees, and moderate spenders (ie, at least 1 year outside of the top 10%). Nondually eligible NJ Medicaid/CHIP enrollees in 2011. One fourth of extreme spenders in 2011 remained in that category throughout 2011-2014. Almost all (89.3%) of the persistently extreme spenders were aged, blind, or disabled. Within the aged, blind, or disabled population, the strongest predictors of persistently extreme spending were diagnoses involving developmental disability, HIV/AIDS, central nervous system conditions, psychiatric disorders, type 1 diabetes, and renal conditions. Individuals in nursing facilities and those with very high risk scores were more likely to die or have persistently high spending than to have persistently extreme spending. The study highlights unique features of spending persistence within Medicaid/CHIP and provides methodological contributions to the broader persistence literature.

Thromboembolic event rate in paroxysmal and persistent atrial fibrillation: Data from the GISSI-AF trial

PubMed Central

2013-01-01

Background Few data on the thromboembolic (TE) risk of paroxysmal and persistent atrial fibrillation (AF) are available. This study aimed to assess the incidence of TE events in paroxysmal and persistent AF. Methods We performed a subset post hoc analysis of 771 patients with paroxysmal and 463 with persistent AF enrolled in the multicenter, prospective, randomized, double-blind, placebo-controlled GISSI-AF trial - comparing the efficacy of valsartan versus placebo in preventing AF recurrences – where the choice of antithrombotic treatment was left to the judgment of the referring physician. TE and major outcome events were centrally validated. AF recurrences were detected by frequent clinic visits and a transtelephonic monitoring device with weekly and symptomatic transmissions. Results Eighty-five percent of patients had a history of hypertension, and the 7.7% had heart failure, left ventricular dysfunction, or both. The mean CHADS2 score was 1.41±0.84. TE and major bleeding events were observed at a low incidence among the overall population at 1-year follow-up (0.97% and 0.81%, respectively). The univariate and multivariable analyses revealed no statistically significant differences in the incidence of TE, major bleeding events or mortality in paroxysmal and persistent AF patients. TE events were more common among women than men (p=0.02). The follow-up examination showed under- or overtreatment with warfarin in many patients, according to guideline suggestions. Warfarin was more frequently prescribed to patients with persistent AF (p<0.0001) and patients with AF recurrences (p<0.0001). AF recurrences were noninvasively detected in 632 (51.2%) patients. In patients without AF recurrences, the TE event rate was 0.5% versus 1.74%, 1.28%, and 1.18% for those with only symptomatic, only asymptomatic or both symptomatic and asymptomatic AF recurrences, respectively, but the difference was not statistically significant, even after adjusting for warfarin treatment and the CHADS2 score (HR 2.93; CI 95%; 0.8-10.9; p=0.11). Conclusions TE and major bleeding events showed a very low incidence in the GISSI-AF trial population, despite under- or overtreatment with warfarin in many patients. TE events had a similar rate in paroxysmal and persistent AF. Trial registration Trial registration number: NCT00376272 PMID:23586654

Background The electrocardiographic diagnostic dyad of emphysema, namely a combination of the frontal vertical P-vector and a narrow QRS duration, can serve as a quasidiagnostic marker for emphysema, with specificity close to 100%. We postulated that the presence of left ventricular hypertrophy in emphysema may affect the sensitivity of this electrocardiographic criterion given that left ventricular hypertrophy generates prominent left ventricular forces and may increase the QRS duration. Methods We reviewed the electrocardiograms and echocardiograms for 73 patients with emphysema. The patients were divided into two groups based on the presence or absence of echocardiographic evidence of left ventricular hypertrophy. The P-vector, QRS duration, and forced expiratory volume in one second (FEV1) were computed and compared between the two subgroups. Results There was no statistically significant difference in qualitative lung function (FEV1) between the subgroups. There was no statistically significant difference in mean P-vector between the subgroups. The mean QRS duration was significantly longer in patients with left ventricular hypertrophy as compared with those without left ventricular hypertrophy. Conclusion The presence of left ventricular hypertrophy may not affect the sensitivity of the P-vector verticalization when used as a lone criterion for diagnosing emphysema. However, the presence of left ventricular hypertrophy may significantly reduce the sensitivity of the electrocardiographic diagnostic dyad in emphysema, as it causes a widening of the QRS duration.

Abstract Rationale: To date, little is known regarding the neural mechanisms of the functional recovery of language after repetitive transcranial magnetic stimulation (rTMS) in aphasia. Our aim was to investigate the mechanism that underlies rTMS and speech training in a case report. Patient concerns and diagnoses: We report the case of a 39-year-old woman who was initially diagnosed with conduction aphasia following a left hemisphere stroke. Interventions: The rTMS location comprised the left Broca area, and a frequency of 5 Hz for 20 min/d for 10 days during a 2-week period was used. She had received speech rehabilitation training 1 month after stroke. Functional magnetic resonance imaging (fMRI) and diffusion tensor imaging were used to investigate the functional and microstructural changes before and after rTMS treatment. Outcomes: The results demonstrated that the Western Aphasia Battery scores significantly improved for language ability at 2 weeks post-treatment, and the gains were steadily increased at 2.5 months post-treatment. The fMRI results indicated a more focused activation pattern and showed significant activation in the left dominant hemisphere relative to the right hemisphere, especially in the perilesional areas, post-treatment during 2 language tasks compared with pretreatment. Moreover, the fractional anisotropy increased in the left superior temporal gyrus, which comprises an important area that is involved in language processing. Lessons: Our findings suggest that rTMS combined with speech training improved the speech-language ability of this chronic conduction aphasia patient and enhanced the cerebral functional and microstructural reorganization.

Cardiac myxoma is known to cause repeated events of cerebral embolism. Soft and irregularly shaped myxomas with high mobility are associated with a higher occurrence of cerebral embolism. In contrast, nonmobile cardiac myxomas with a round regular shape are rarely considered to be a cause of cerebral embolism. In this case, we present a patient with recurrent cerebral embolism associated with a small and nonmobile cardiac myxoma of round regular shape. A 76-year-old Japanese man presented to our hospital with weakness in his right upper extremity. He had a history of right frontal lobe infarction in the previous month. T2-weighted magnetic resonance imaging revealed an area of hyperintensity in the left precentral gyrus, indicating acute cerebral infarction. Transthoracic echocardiography revealed normal left ventricular function and no abnormalities. However, transesophageal echocardiography showed a small and nonmobile left atrial tumor with round regular shape attached to the ostium secundum of the atrial septum. Based on these findings, we diagnosed recurrent cerebral infarction due to embolization caused by left atrial myxoma, and cardiac tumor extraction was performed on hospitalization day 36. The excised tumor measured 0.6 × 0.6 × 0.5 cm and was diagnosed as cardiac myxoma by histologic examination. Even small and nonmobile cardiac myxomas with a round regular shape may cause recurrent cerebral infarction. The diagnosis of this type of atrial myxoma is elusive and transesophageal echocardiography was an effective method of detection. In a clinical situation, this type of cardiac myxoma may be overlooked as a cause of cerebral infarction.

Atrial low-voltage zones (LVZs) may be related to maintenance of atrial fibrillation (AF). The influence of left atrial (LA) contact areas (CoAs) on reentrant or rotor-like sources maintaining AF has not been investigated. Forty patients with persistent AF (PsAF) were analyzed. Three representative CoA regions in the LA (ascending aorta: anterior wall; descending aorta: left inferior pulmonary vein; and vertebrae: posterior wall) were visualized by enhanced CT. Using circular catheters, the LVZs (<0.5 mV) were assessed after restoration of SR, and local activation mapping and frequency domain analyses were performed after induction of AF. Circular activation during AF was visually defined as sites with ≥2 rotations by serial electrograms encompassing >80% of the mean AF cycle length. A pivot was defined as the core of the localized circular activation. Anterior (39/40 patients, 98%), left pulmonary vein antrum (27/40, 68%), and posterior (19/40, 48%) CoAs were identified, and 80% (68/85) of those sites were overlapped by or close (<3 mm) to LVZs. Thirty-six (90%) patients demonstrated circular activation (3.1±1.7 sites/patients) along with significantly higher organized dominant frequencies (6.3 ± 0.5 Hz, regularity-index: 0.26 [0.23-0.41]) within the LA, and the average electrogram amplitude of those pivots was 0.30 mV (0.18-0.52). Of those sites, 55% (66/120) were located at or close to CoA regions. Catheter ablation including of LVZs neighboring CoAs terminated AF in 9 (23%) patients. External anatomical structures contacting the LA may be related to unique conduction properties in diseased myocardium necessary for PsAF maintenance. © 2016 Wiley Periodicals, Inc.

Patent ductus arteriosus closure using an Amplatzer™ ventricular septal defect closure device

The ductus arteriosus originates from the persistence of the distal portion of the left sixth aortic arch. It connects the descending aorta (immediately distal to the left subclavian artery) to the roof of the main pulmonary artery, near the origin of the left pulmonary artery. Persistence of the duct beyond 48 h after birth is abnormal and results in patent ductus arteriosus (PDA). PDA is rare in adults because it is usually discovered and treated in childhood. Mechanical closure remains the definitive therapy because the patency of ductus arteriosus may lead to multiple complications, depending on the size and flow through the ductus. PDA closure is indicated in patients with symptoms and evidence of left heart enlargement, and in patients with elevated pulmonary pressures when reversal is possible. Transcatheter closure is the preferred technique in adults because it avoids sternotomy, reduces the length of hospital stay and is associated with fewer complications compared with surgery. First demonstrated in 1967, both the technique and the occluder devices used have since evolved. However, designing an ideal PDA occluder has been a challenge due to the variability in size, shape and orientation of PDAs. The present article describes a case involving a 35-year-old woman who presented to the Center for Advanced Heart Failure (Houston, USA) with congestive heart failure due to a large PDA, which was successfully occluded using an Amplatzer (St Jude Medical, USA) muscular ventricular septal defect closure device. The wider waist and dual-retention discs of these ventricular septal defect closure devices may be important factors to consider in the future development of devices for the occlusion of large PDAs.

Reexpansion of a pulmonary atelectasis is often difficult, even after removing possible causes of bronchial obstruction. Chest ultrasounds, inexpensive and readily available at the patient bedside, may offer valuable support to guide recruitment maneuvers. We report the case of a 57-year-old woman that developed a complete collapse of the left lung seven days after undergoing an intestinal resection for perforation. A mucous plug occluding the main bronchus was removed with bronchoscopy, but persistent hypoxemia required mechanical ventilation; 24 hours later, an attempt to wean the patient from the ventilator failed. Chest X-rays revealed the persistence of a partial collapse of the left inferior lobe associated with a pleural effusion. A chest ultrasound confirmed the presence of a lung consolidation and of a modest pleural effusion. Manual reexpansion was then attempted, and ventilatory pressures as well as the duration of forced inspirations were based on real-time ultrasound images. Complete reexpansion was achieved within a few minutes and confirmed by chest X-ray. The patient was weaned from mechanical ventilation on the same day and discharged from ICU three days later.

Mutations in the Norrie Disease gene, Norrie Disease Pseudoglioma (NDP) lead to a phenotypically heterogeneous group of retinopathies. We report a novel mutation in the NDP gene identified in a patient whose clinical presentation was suggestive of unilateral persistent fetal vasculature (PFV). Ophthalmic examinations, ocular ultrasounds and sequence analysis of the exons of the NDP gene on peripheral blood DNA were performed. A four-month-old boy was referred to our institution for presumed unilateral retinoblastoma. The clinical and ultrasonographic exams were consistent with PFV and retinal detachment of the left eye as well as retinal fibrovascular changes in the right eye. A vitrectomy of the left eye revealed the absence of a retrolenticular stalk and mutation analysis of the NDP gene of the proband and mother demonstrated a novel missense mutation at codon 66, designated as c. 196G > A at the cDNA level and E66K at the protein level. We report a novel mutation in the NDP gene in a patient whose presentation demonstrates the phenotypic heterogeneity of NDP-related disorders.

The eventration of diaphragm is usually found incidentally on chest X-ray or sometimes presented as acute gastric volvulus. However, colonic volvulus on splenic flexure area complicated by diaphragmatic eventration is extremely rare. A 25 year old man complained of upper abdominal pain for three days. He had a history of brain injury during infant period, and had epilepsy and mental retardation. Plain chest X-ray showed left diaphragmatic eventration and marked dilatation of colon on splenic flexure area which had not been changed for last three years. Barium enema showed bird beak appearance on distal colon near the splenic flexure. Colonoscopic reduction failed. After decompression with rectal and nasogastric tubes, colonic volvulus was relieved. To prevent the recurrence of volvulus, we performed segmental resection of left colon including splenic flexure area and repaired the left diaphragmatic eventration. After the operation, the patient had no further recurrent episode of volvulus although ileus persisted.

This is a case of both congenital left ventricular (LV) free wall submitral aneurysm and left atrial appendage aneurysm with 6 years of clinical follow-up. Each lesion is a rare entity, and to the best of our knowledge, this is the first case in medical literature of both lesions occurring in the same patient, raising the likelihood of a common etiology. The workup was initiated in the third trimester of fetal life with irregular heart rate and abnormal fetal ultrasound and echocardiogram at that time. The patient required emergent atrial appendage plication due to blood clot formation and suffered from multiple other complications including ventricular ectopy and surgically induced pseudoaneurysm. Follow-up interval echocardiograms have revealed continued good LV function with persistent LV aneurysm. In review of the case, there were several potential in utero causes including maternal viral upper respiratory infection and bacteriuria with exposure to amoxicillin. These as well as other considerations are discussed along with a brief review of these rare lesions, usual presentation, and known associations.

Marfan syndrome, bicuspid aortic valve, and/or coarctation of the aorta are associated with medial abnormalities of the ascending aortic or para-coarctation aorta. Medial abnormalities in the ascending aorta are prevalent in other type of patients with a variety of CHDs such as single ventricle, persistent truncus arteriosus, transposition of the great arteries, hypoplastic left heart syndrome, and tetralogy of Fallot, encompassing a wide age range and may predispose to dilatation, aneurysm, and rapture necessitating aortic valve and root surgery. These CHDs exhibit ongoing dilatation of the aortic root and reduced aortic elasticity and increased aortic stiffness that may relate to intrinsic properties of the aortic root. These aortic dilatation and increased stiffness can induce aortic aneurysm, rapture of the aorta, and aortic regurgitation, but also provoke left ventricular hypertrophy, reduced coronary artery flow, and left ventricular failure. Therefore, a new clinical entity can be used to call this association of aortic pathophysiological abnormality, aortic dilation, and aorto-left ventricular interaction - "aortopathy".

Aims: To compare different methods in order to assess adherence and persistence with oral endocrine therapy in women diagnosed with breast cancer (BC) in Catalonia. Materials and methods: This study covered all women newly diagnosed with stage I, II or IIIa BC and positive hormone receptors at six hospitals in Catalonia (Spain) in 2004. Adherence was assessed on the basis of physician report and patient self-report using a telephone questionnaire. Persistence was measured by refill prescriptions. We used the Kappa index to compare adherence measures and logistic regression to evaluate adherence-related risk factors. Results: The study covered a total of 692 women. Adherence ranged from 92% (self-report) to 94.7% (physician report), depending on the measure used; persistence was 74.7% at 5 years of follow-up. Low concordance between measures was observed (Kappa range: 0.018–0.267). Patients aged 50–74 years showed higher adherence than those aged <50 years. Adherence was also associated with: adjuvant chemotherapy and sequential hormonal therapy. Conclusions: Concordance between the different measures was remarkably low, indicating the need for further research. Adherence is an issue in the management of BC patients taking oral drugs, and should be assessed in clinical practice. PMID:22955858

Prevalence of allergies is different around the world. Allergic rhinitis is a common chronic disease in children. Intelligence quotient (IQ) is an indicator of efficacy and many factors including chronic diseases may affect it. This study compares the IQs of children diagnosed with persistent or perennial allergic rhinitis with healthy children. This was a comparative study that was conducted from June 2011-May 2013 in an academic referral clinic. In this study, 90 patients aged 6- to 14-yearsold who were diagnosed with persistent or perennial allergic rhinitis and were compared to 90 age and gender match healthy patients from their respective families. The Wechsler Intelligence Scale for Children was used to divide and calculate overall IQ, verbal IQ, and practical IQ. The t-test and chi square were used to analyze quantitative variables and qualitative variables, respectively. In this study, out of total 180 children, 90 (50%) in the case group and 90 children (50%), the control group participated for IQ comparison. One hundred (57%) were male and 80 (43%) were female. The overall IQ for allergic rhinitis patients and healthy patients was 109.2 and 107.5, respectively. This difference was not considered significant. Furthermore, there was no significant difference between the IQ scores of males and females. Although allergic rhinitis is a chronic disease and effects quality of life, there were no identifiable negative effects on IQ.

Objective Studies of schizophrenia have not clearly defined handedness as a differentiating variable. Moreover, the relationship between thought disorder and anatomical anomalies has not been studied extensively in left-handed schizophrenic men. The twofold purpose of this study was to investigate gray matter volumes in the superior temporal gyrus of the temporal lobe (left and right hemispheres) in left-handed schizophrenic men and left-handed comparison men, in order to determine whether thought disorder in the left-handed schizophrenic men correlated with tissue volume abnormalities. Method Left-handed male patients (N=8) with DSM-III-R diagnoses of schizophrenia were compared with left-handed comparison men (N=10) matched for age, socioeconomic status, and IQ. Magnetic resonance imaging (MRI) with a 1.5-T magnet was used to obtain scans, which consisted of contiguous 1.5-mm slices of the whole brain. MRI analyses (as previously defined by the authors) included the anterior, posterior, and total superior temporal gyrus in both the left and right hemispheres. Results There were three significant findings regarding the left-handed schizophrenic men: 1) bilaterally smaller gray matter volumes in the posterior superior temporal gyrus (16% smaller on the right, 15% smaller on the left); 2) a smaller volume on the right side of the total superior temporal gyrus; and 3) a positive correlation between thought disorder and tissue volume in the right anterior superior temporal gyrus. Conclusions These results suggest that expression of brain pathology differs between left-handed and right-handed schizophrenic men and that the pathology is related to cognitive disturbance.

Objective The purpose of this study was to see whether participants who persist in their stutter have poorer sensitivity in a backward masking task compared to those participants who recover from their stutter. Design The auditory sensitivity of 30 children who stutter was tested on absolute threshold, simultaneous masking, backward masking with a broadband and with a notched noise masker. The participants had been seen and diagnosed as stuttering at least 1 year before their 12th birthday. The participants were assessed again at age 12 plus to establish whether their stutter had persisted or recovered. Persistence or recovery was based on participant's, parent's and researcher's assessment and Riley's [Riley, G. D. (1994). Stuttering severity instrument for children and adults (3rd ed.). Austin, TX: Pro-Ed.] Stuttering Severity Instrument-3. Based on this assessment, 12 speakers had persisted and 18 had recovered from stuttering. Results Thresholds differed significantly between persistent and recovered groups for the broadband backward-masked stimulus (thresholds being higher for the persistent group). Conclusions Backward masking performance at teenage is one factor that distinguishes speakers who persist in their stutter from those who recover.

 Education objectives: Readers of this article should: (1) explain why auditory factors have been implicated in stuttering; (2) summarise the work that has examined whether peripheral, and/or central, hearing are problems in stuttering; (3) explain how the hearing ability of persistent and recovered stutterers may differ; (4) discuss how hearing disorders have been implicated in other language disorders.

The persistence of cognitive deficits in remitted and unremitted ADHD: a case for the state-independence of response inhibition

McAuley, Tara; Crosbie, Jennifer; Charach, Alice; Schachar, Russell

2014-01-01

Background Response inhibition, working memory, and response variability are possible endophenotypes of ADHD based on their association with the disorder and evidence of heritability. One of the critical although rarely studied criteria for a valid endophenotype is that it persists despite waxing and waning of the overt manifestations of the disorder, a criterion known as state-independence. This study examined whether these aspects of cognition exhibit state-independence in ADHD. Methods One hundred and seventy-nine children diagnosed with ADHD in a rigorous baseline assessment were contacted for follow-up assessment in adolescence. Of this sample, 130 (73%) were reascertained. At follow-up, children previously diagnosed with ADHD were identified as remittent (n = 24), persistent (n = 64), or in partial remission (n = 42) based on symptoms and impairment of the disorder. Response inhibition, working memory, and response variability were assessed both in childhood (baseline) and adolescence (follow-up) and were compared with age-matched controls (40 children and 28 adolescents) seen at either time point. Results Relative to controls, ADHD children showed baseline deficits in response inhibition, working memory, and response variability. Only the group difference in response inhibition remained significant in adolescence. In general, cognitive performance among ADHD participants improved with age and did so regardless of changes in ADHD symptoms and impairment. Within the ADHD group, however, cognitive performance in childhood and in adolescence did not differ amongst those with persistent, remittent, and partially remittent forms of the disorder. Conclusions Results demonstrate that response inhibition not only distinguishes ADHD children from their unaffected peers but is also state-independent, such that deficits remain present irrespective of changes in the disease phenotype. In other words, inhibitory deficits measured in childhood persist into adolescence even when the ADHD phenotype remits. These findings provide further evidence that the ability to stop prepotent actions is an endophenotype of ADHD. PMID:24261515

To estimate real-world treatment patterns, safety, and relapse outcomes of subcutaneous (sc) interferon (IFN) β-1a (Rebif) vs dimethyl fumarate (DMF; Tecfidera), to treat relapsing-remitting multiple sclerosis (RRMS). A US retrospective chart review of 450 randomly selected adults newly diagnosed with RRMS who received sc IFN β-1a (n = 143) or DMF (n = 307) was conducted. Patients were either (a) treatment-naïve, initiating first-line treatment with sc IFN β-1a or DMF, or (b) previously treated, switching to sc IFN β-1a or DMF. Two years' follow-up data were captured. Patient characteristics, persistence, and adverse events between treatment groups were compared using t-tests or Chi-square tests. Kaplan-Meier curves with log-rank tests and Cox proportional hazards models were used to compare time to, and risk of non-persistence. Annualized Relapse Rates (ARR) were calculated using a robust variance Poisson model adjusting for covariates. Propensity scores were used to address possible selection bias. One hundred and twelve patients became non-persistent, most commonly due to an adverse event (n = 37). No difference was observed in time to overall non-persistence between sc IFN β-1a and DMF patients. Among treatment-naïve patients, those receiving DMF had 2.4-times the risk (HR = 2.439, 95% CI = 1.007-5.917, p = .0483) of experiencing a discontinuation than patients receiving sc IFN β-1a. Non-persistent patients receiving DMF had 2.3-times the risk (HR = 2.311, 95% CI = 1.350-3.958, p = .0023) of experiencing an adverse event at a given time point than patients prescribed sc IFN β-1a. No differences in relapse risk or ARR between sc IFN β-1a- and DMF-treated patients were observed. sc IFN β-1a-treated patients had comparable persistence and relapse outcomes, and better safety outcomes vs DMF-treated patients across 2 years.

Upper airway obstruction is commonly misdiagnosed as asthma. We report on four children with recurrent respiratory symptoms who had been erroneously diagnosed as having asthma and who received anti-asthma medication for several years. The evaluation of spirometry tracing was neglected in all cases. Subglottic stenosis, tracheomalacia secondary to tracheo-esophageal fistula, double aortic arch, and vocal cord dysfunction were suspected by direct inspection of the flow-volume curves and eventually diagnosed. The value of clinical history and careful evaluation of spirometry tracing in children with persistent respiratory symptoms is critically discussed. © 2015 John Wiley & Sons A/S.

67 year old patient with chronic heart failure and persistent atrial fibrillation had overdosed glycosides for several months. The symptoms of gastrointestinal system and nervous system appeared after long term therapy with toxic doses of glycosides. Originally depression was diagnosed based on the central nervous system disturbances. Even though overdose of glycosides was diagnosed the blood serum glycoside level was within the therapeutic limits. Based on the precise analysis of the data, it was concluded that the reason for normal blood serum glycoside level in this case was coexisting hyperthyreosis.

Background Left atrial enlargement is considered to be a robust, strong, and widely acceptable indicator of cardiovascular outcomes. Echocardiography is the gold standard for measurement of left atrial size, but electrocardiography can be simple, cost-effective, and noninvasive in clinical practice. This study was undertaken to assess the diagnostic accuracy of an established electrocardiographic criterion for left atrial enlargement, taking 2-dimensional echocardiography as the gold-standard technique. Methods A cross-sectional study was conducted on 146 consecutively selected patients with the complaints of dyspnea and palpitation and with a murmur detected on clinical examination, from September 10, 2016 to February 10, 2017. Electrocardiography and echocardiography were performed in all patients. Patients with a negative P wave terminal force in lead V 1  > 40 ms·mm on electrocardiography or left atrial dimension > 40 mm on echocardiography were classified as having left atrial enlargement. Sensitivity and specificity were calculated to assess the diagnostic accuracy. Results Taking 2-dimensional echocardiography as the gold-standard technique, electrocardiography correctly diagnosed 68 patients as positive for left atrial enlargement and 12 as negative. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of electrocardiography for left atrial enlargement were 54.4%, 57.1%, 88.3%, 17.4%, and 54.8%, respectively. Conclusion The electrocardiogram appears to be a reasonable indicator of left atrial enlargement. In case of nonavailability of echocardiography, electrocardiography can be used for diagnosis of left atrial enlargement.

Hemolytic uremic syndrome (HUS) is characterized by the presence of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney failure. It is the leading cause of acute kidney failure in children under 3 years of age. A variable number of patients develop proteinuria, hypertension, and chronic renal failure. To evaluate the renal involvement in pediatric patients diagnosed with HUS using the microalbumin/creatinine ratio. Descriptive concurrent cohort study that analyzed the presence of microalbuminuria in patients diagnosed with HUS between January 2001 and March 2012, who evolved without hypertension and normal renal function (clearance greater than 90ml/min using Schwartz formula). Demographic factors (age, sex), clinical presentation at time of diagnosis, use of antibiotics prior to admission, and need for renal replacement therapy were evaluated. Of the 24 patients studied, 54% were male. The mean age at diagnosis was two years. Peritoneal dialysis was required in 45%, and 33% developed persistent microalbuminuria. Antiproteinuric treatment was introduce in 4 patients, with good response. The mean follow-up was 6 years (range 6 months to 11 years). The serum creatinine returned to normal in all patients during follow up. The percentage of persistent microalbuminuria found in patients with a previous diagnosis of HUS was similar in our group to that described in the literature. Antiproteinuric treatment could delay kidney damage, but further multicenter prospective studies are necessary. Copyright © 2015. Publicado por Elsevier España, S.L.U.

Non-Hodgkin lymphoblastic lymphomas are very uncommon tumors that rarely involve the heart; however, when they do, they typically cause cardiac symptoms. Herein, we describe the case of a young woman who presented with respiratory symptoms. These were caused by a high-grade lymphoblastic lymphoma, which originated in the left inferior pulmonary vein and extended into the left atrium. The tumor was surgically debulked, but it recurred in 1 month, and the patient underwent chemotherapy. Six months later, she had recurrent respiratory symptoms, and echocardiography revealed a persistent mass in the left lower lobar vein. A modified chemotherapy regimen led to complete resolution of the tumor within 2 months. We are unaware of other reports of a primary cardiac non-Hodgkin lymphoblastic lymphoma with this unusual site of origin and rare manifestation of symptoms. PMID:21841872

Left atrial scarring is recognised as a critical component in the maintenance of atrial fibrillation and is associated with the failure of interventional treatment. Diminished bipolar voltage (LV) has been proposed as a useful tool for left atrial scar quantification. We hypothesised that, due to its anatomic location, signals on the coronary sinus catheter might be used to predict the amount of left atrial low voltage. A total of 124 patients (42% women, average age 66 ± 9 years) were included. Forty-one with paroxysmal and 83 with persistent atrial fibrillation. Left atrial low-voltage (<0.5 mV, measured during sinus rhythm) area size and distribution varied considerably among the included patients (mean: 34.9%; maximum: 94.6%; minimum: 0.4%). Spearman correlation revealed a strong negative correlation between bipolar voltage of the signals on the coronary sinus catheter and the amount of left atrial scarring (R = -0.778, p < .0001). The optimal CS voltage cut off for prediction of left atrial low-voltage size of ≥50% was 1.9 mV with an area-under-the receiver-operating-characteristic (ROC) curve of 0.982, a sensitivity of 97% and a specificity of 98%. There is a strong negative correlation between the size of left atrial low-voltage areas (LVA) and coronary sinus signal amplitude. With increasing left atrial LVA size, CS signal amplitudes decrease, and vice versa. On the basis of these findings, average CS signal amplitudes of ≤1.9 mV can be used as a predictor for a left atrial low-voltage size of ≥50%.

Background: Double gallbladder is a rare anomaly of the biliary tract. Double gallbladder arising from the left hepatic duct was previously reported only once in the literature. Case Report: A case of symptomatic cholelithiasis in a double gallbladder, diagnosed on preoperative ultrasound, computed tomography (CT) and endoscopic retrograde cholangiopancreatogram (ERCP) is reported. At laparoscopic cholangiography via the accessory gallbladder no accessory cystic duct was visualized. After conversion to open cholecystectomy, the duplicated gallbladder was found to arise directly from the left hepatic duct; it was resected and the duct repaired. Conclusions: We emphasize that a careful intraoperative cholangiographic evaluation of the accessory gallbladder is mandatory in order to prevent inadvertent injury to bile ducts, since a large variety of ductal abnormality may exist.

Left-ventricular ejection fraction (LVEF) and abnormalities of regional wall motion (WMA) were studied by means of radionuclide ventriculography in 41 patients prospectively diagnosed as having chronic Chagas' disease. Thirteen patients were asymptomatic (ASY), 16 were arrhythmic (ARR), and 12 had congestive heart failure (CHF). Mean LVEF was normal in ASY but markedly depressed in CHF. Regional WMAs were minimal in ASY and their severity increased in ARR. Most CHFs (75%) had diffuse hypokinesia of the left ventricle. Seven patients had a distinct apical aneurysm. Correlation between radionuclide and contrast ventriculography data was good in 17 patients. Selective coronary arteriography showedmore » normal arteries in all patients.

A 50-year-old female was admitted to a local hospital because of dyspnea, and diagnosed as having left heart failure secondary to mitral regurgitation. After the improvement of congestive heart failure, polyarthralgia, fever, and positive anti-nuclear antibody were pointed out. She was referred to our hospital for the further evaluation. Serological test showed anti-double stranded DNA antibodies, anti-SS-A antibodies, anti-beta 2-GPI antibodies and biological false positive for syphilis. The diagnosis of SLE has been made from the clinical signs and the serology. Therefore mitral valvular lesion of this patient was considered to be one of the symptoms of SLE. We reported a rare case in which left heart failure was a initial clinical manifestation of SLE.

Introduction Excess dilatation of the left atrium >65 mm is known in the literature as gigantic atrium. This dilation is most commonly encountered in the mitral insufficiency of rheumatic etiology, but also in severe prolapses of the mitral valve, permanent atrial fibrillation, and at the left right shunt with cardiac insufficiency. Case report In this paper is presented a case study of echocardiographically verified giant thrombus in left atrium in a 50 years old female patient aged 50 hospitalized because of tiredness, choking, heartburn and urinary tract symptoms. The patient had rheumatic fever at age of 18 years. At age of 35, she was diagnosed with mitral stenosis. In permanent atrial fibrillation with anamnestic data on the previous cerebrovascular stroke (CVI) and the repeated transitional ischemic seizures. Echocardiographic examination confirmed severe mitral stenosis with moderate aortic insufficiency and gigantic left atrium (LA) with gigantic thrombus. Invasive diagnostics were indicated and performed, followed by an acute cardiac surgery including left atrial thrombectomy and implantation of the mechanical aortic and mitral valve. The surgical course was without complications. Conclusion On eleven postoperative day, after mobilization, the patient experiences stroke with motor aphasia. She was clinically recovering from stroke consequences, and remains cardiollogically stable. PMID:29416208

To investigate whether seizure lateralization affects sleep macrostructure in patients with left and right temporal lobe epilepsy (TLE), as rapid eye movement (REM) sleep is shorter in patients with right hemispheric cerebral infarction than with left. We retrospectively analyzed data from 16 patients with TLE (6 men and 10 women aged 34.9 ± 11.4 years) who underwent polysomnography as well as long-term video electroencephalography. Ten patients were diagnosed with left TLE and six patients with right TLE. Sleep stages and respiratory events were scored based on the American Academy of Sleep Medicine criteria. Sleep and respiratory parameters were compared between the patient groups. Percentage of REM stage sleep was significantly (p < 0.05) lower in patients with left TLE (median 8.8 %, interquartile range 5.5-13.8 %) than in patients with right TLE (median 17.0 %, interquartile range 14.1-18.3 %). The other parameters showed no significant differences. Shorter REM sleep in patients with left TLE sharply contrasts with the previous report of shorter REM sleep in patients with right cerebral infarction. Laterality of the irritative epileptic focus versus destructive lesion may have different effects on the sleep macrostructures.

A 75-year-old woman was referred for advice regarding surface electrocardiographic modifications after the initiation of rivastigmine. In our patient, the baseline ECGs appeared perfectly normal. However, the initiation of a cholinesterase inhibitor unmasked a left lateral accessory pathway that had never been diagnosed before. Although cholinesterase inhibitors are known to increase vagal tone, the PR interval was shortened after rivastigmine administration, thus excluding this hypothesis to explain the appearance of the accessory pathway. Therefore, we hypothesized that cholinesterase inhibitors may have increased conduction velocity in the accessory pathway or in the atria. Copyright © 2017 Elsevier Inc. All rights reserved.

The case of a 67-year-old man is presented. He was admitted for the presence of a left parietal tumour with progressive growing, without any other objective or subjective symptomatology. CT-scan detects a left parietal osteolytic area. The histopathological aspect suggested an adenocarcinomatous metastasis with papillary pattern, moderately differentiated. With the purpose of diagnosing the original tumour, immunnohistochemical techniques were performed, which led to a diagnosis of a thyroidian carcinoma. At the histological examination of the surgical extirpated thyroid, it was proved to be a papillary carcinoma (Chan, 1990, Hay, 1990), the follicular pattern.

Toxoplasmosis is an infection caused by the intracellular parasite, Toxoplasma gondii. Immunocompetent persons with primary infection are usually asymptomatic, but latent infection can persist for the life of the host. There is a risk of reactivating infection at a later time should the individual become immunocompromised, even if infection was asymptomatic or only mildly symptomatic initially. Axillary lymph nodes receive 85% of the lymphatic drainage from the breast. Lymph node metastases are relatively common even with invasive breast cancers ≤1 cm in size. Here, we report a case of toxoplasma lymphadenitis in a female adult patient mimicking a malign breast lymphadenopathy of a left breast mass.

A young female secretary developed a writing disorder, exclusively expressed when using a word processor, following an ischemic vascular event involving the insula and the right posterior parietal region. There was no disturbance of laterality. The neurological examination, completed by neuropsychological tests eliminated any persistent phasic or gnostic disorders. The analysis of the text produced revealed abnormalities leading to the conclusion that the left hand was responsible for all the errors observed. A sensorimotor integration disorder produced a melokinetic apraxia which appeared to be the cause of the writing disorder which would have most likely remained unknown had the subject not been a secretary.

A 80-years-old woman suddenly presented with aphasia, right hemiparesis, and dysesthesia. MRA showed the left middle cerebral artery occlusion. She was diagnosed as hyperacute ischemic stroke. She was treated with intravenous recombinant tissue plasminogen activator and underwent endovascular thrombectomy. On admission, she had a fever and high C reactive protein, and was treated with antibiotic therapy. The pathological diagnosis of the retrieved thrombus revealed the cluster of the gram positive cocci. The blood culture was negative and thransthoracic echocardiogram did not detect the vegetation. She was finally diagnosed as cardioembolic stroke due to infective endocarditis based on the pathological diagnosis of the retrieved thrombus. The pathological diagnosis of the retrieved thrombus was quite important to clarify the cause of ischemic stroke.

Non-invasive identification of stable rotors and focal sources for human atrial fibrillation: mechanistic classification of atrial fibrillation from the electrocardiogram.

PubMed

Jones, Aled R; Krummen, David E; Narayan, Sanjiv M

2013-09-01

To develop electrocardiogram (ECG) tools to quantify the number of sources for atrial fibrillation (AF), i.e. spatially stable rotors and focal impulses, and whether they lie in right or left atrium. Intracardiac mapping has recently shown that paroxysmal and persistent AF is sustained by rotors or focal sources that are stable in location and thus targets for limited ablation [focal impulse and rotor modulation (FIRM)] to eliminate AF. Importantly, the numbers and locations of concurrent sources determine both the complexity of AF and the approach for ablation. In 36 AF patients (n = 29 persistent, 63 ± 9 years) in the CONventional ablation with or without Focal Impulse and Rotor Modulation (CONFIRM) trial, we developed phase lock (PL) to quantify spatial repeatability of ECG 'F-waves' between leads over time. Phase lock spectrally quantifies the angle θ between F-wave voltages in planes formed by ECG leads I, aVF, and V1 at successive points in time. We compared PL with ECG spectral dominant frequency (DF) and organizational index (OI) to characterize stable rotors and focal sources validated by intracardiac FIRM mapping. Focal impulse and rotor modulation ablation alone at ≤3 sources acutely terminated and rendered AF non-inducible or substantially slowed AF in 31 of 36 patients. Receiver operating characteristics of PL for this endpoint had area under the curve (AUC) = 0.72, and the optimum cut-point (PL = 0.09) had 74% sensitivity, 92% positive predictive value (PPV). Receiver operating characteristics areas for OI and DF were 0.50 and 0.58, respectively. Left (n = 28) or right (n = 3) atrial sources were localized by PL with AUC = 0.85, sensitivity 100%, PPV 30%, and negative predictive value 100%. Spectral DF provided AUC = 0.79. Notably, PL did not comigrate with diagnosis of paroxysmal or persistent AF (P = NS), unlike ECG DF. The novel metric of ECG PL identifies patients with fewer (≤3) or greater numbers of stable rotors/focal sources for AF, validated by intracardiac FIRM mapping, and localized them to right or left atria. These data open the possibility of using 12-lead ECG analyses to classify AF mechanistically and plan procedures for right- or left-sided FIRM ablation.

Twenty-four female partners of firefighters participating in recovery efforts associated with the 1995 terrorist bombing in Oklahoma City were assessed 43 to 44 months later. Disaster experiences, psychiatric diagnoses, posttraumatic stress symptoms, and autonomic reactivity in response to an interview about the bombing were examined. Most of the participants with postbombing disorders suffered from pre-existing conditions. The majority found the bombing a "terrible" or "shocking" experience. One participant met all DSM-III-R symptom group criteria for bombing-related posttraumatic stress disorder, and 40% met both B (intrusive re-experiencing) and D (hyperarousal) criteria. More than one half of the sample exhibited autonomic reactivity on at least one measurement. Those who met symptom group criterion D evidenced greater autonomic reactivity than those who did not, suggesting a link between self-reported posttraumatic stress disorder symptoms of arousal and biological manifestations. Thus, it may be important to assess partners of disaster recovery workers for mental health and physiological consequences related to their indirect exposure as these may persist years after the event, even in the absence of a diagnosable mental disorder.

We aimed to investigate the presence of atrial electromechanical conduction delay in patients with neurocardiogenic syncope, which was diagnosed with head-up tilt table test (HUTT). A total of 29 patients (mean age: 30.6 ± 15.9 years) with vasovagal syncope, as diagnosed by HUTT, and 23 healthy control subjects (mean age: 34.7 ± 16.3 years) with a negative HUTT were enrolled to the study. Atrial electromechanical conduction delay was defined as the time elapsed from the beginning of the P wave in the electrogardiogram to the beginning of the Am wave in tissue Doppler. There was no statistically significant difference between the groups in terms of interatrial conduction delay, whereas the difference was significant with regard to the right intraatrial electromechanical conduction delay (P < 0.01) and the left intraatrial electromechanical conduction delay (P < 0.0001). There was a negative correlation between the left intraatrial electromechanical conduction delay and the right intraatrial electromechanical conduction delay (r = -0.486, P = 0.001), whereas a positive correlation was present with the interatrial electromechanical conduction delay (r = 0.507, P = 0.001). In this study, the tissue Doppler method revealed that there is left and right intraatrial electromechanical conduction delay in patients with vasovagal syncope. The impact and role of atrial conduction delay as a pathophysiological determinant should be confirmed in further studies. ©2013 Wiley Periodicals, Inc.

Atrial septal defect (ASD) is a common congenital heart disease (CHD) in humans, but considered relatively rare in veterinary medicine. However, modern echocardiographic and Doppler techniques currently offer a good view of the morphology of the interatrial septum, thus facilitating earlier detection of ASD in awake animals. In this context, we carried out a retrospective study of cases of recently diagnosed ASD in dogs and cats at the Cardiology Unit of Alfort (2001-2005) using echocardiography combined with colour Doppler mode. ASD was diagnosed in 156 animals and represented 37.7% of all canine and feline CHDs (n = 414). ASD was the most common CHD after mitral dysplasia in both species. Boxer and Domestic shorthair were the most common canine and feline breeds affected. Most defects (98.7%) were secundum-type ASD, without clinical signs in 73.7% of cases. The most common clinical signs included systolic murmur heard over the left heart base (20.2%), exercise intolerance (7.0%), syncope (5.3%), dyspnoea (2.6%) and cough (2.6%). Animals that presented a systolic heart murmur over the left base had a significantly larger ASD than others (P < 0.05). These data suggest that the incidence of ASD is higher than previously assumed. ASD should be suspected, for example, in instances of left basal systolic heart murmur, although its clinical and haemodynamic consequences are usually minor.

We report two cases with internal carotid artery(ICA)aneurysms, in which fusion image effectively indicated the anatomical variations of the anterior choroidal artery (AchoA). Fusion image was obtained using fusion application software (Integrated Registration, Advantage Workstation VS4, GE Healthcare). When the artery passed through the choroidal fissure, it was diagnosed as AchoA. Case 1 had an aneurysm at the left ICA. Left internal carotid angiography (ICAG) showed that an artery arising from the aneurysmal neck supplied the medial occipital lobe. Fusion image showed that this artery had a branch passing through the choroidal fissure, which was diagnosed as hyperplastic AchoA. Case 2 had an aneurysm at the supraclinoid segment of the right ICA. AchoA or posterior communicating artery (PcomA) were not detected by the right ICAG. Fusion image obtained from 3D vertebral angiography (VAG) and MRI showed that the right AchoA arose from the right PcomA. Fusion image obtained from the right ICAG and the left VAG suggested that the aneurysm was located on the ICA where the PcomA regressed. Fusion image is an effective tool for assessing anatomical variations of AchoA. The present method is simple and quick for obtaining a fusion image that can be used in a real-time clinical setting.

Brain metastasis from colorectal cancer is infrequent and carries a poor prognosis. Herein, we present a patient alive 10 years after the identification of a first brain metastasis from sigmoid colon cancer. A 39-year-old woman underwent sigmoidectomy for sigmoid colon cancer during an emergency operation for pelvic peritonitis. The pathological finding was moderately differentiated adenocarcinoma. Eleven months after the sigmoidectomy, a metastatic lesion was identified in the left ovary. Despite local radiotherapy followed by chemotherapy, the left ovarian lesion grew, so resection of the uterus and bilateral ovaries was performed. Adjuvant chemotherapy with tegafur-uracil (UFT)/calcium folinate (leucovorin, LV) was initiated. Seven months after resection of the ovarian lesion, brain metastases appeared in the bilateral frontal lobes and were treated with stereotactic Gamma Knife radiosurgery. Cervical and mediastinal lymph node metastases were also diagnosed, and irradiation of these lesions was performed. After radiotherapy, 10 courses of oxaliplatin and infused fluorouracil plus leucovorin (FOLFOX) were administered. During FOLFOX administration, recurrent left frontal lobe brain metastasis was diagnosed and treated with stereotactic Gamma Knife radiosurgery. In this case, the brain metastases were well treated with stereotactic Gamma Knife radiosurgery, and the systemic disease arising from sigmoid colon cancer has been kept under control with chemotherapies, surgical resection, and radiotherapy.

To investigate whether demographic, clinical and treatment-related risk factors known at treatment initiation can be used to reliably predict future hormonal therapy non-persistence in women with breast cancer, and to inform intervention development. Women with stage I-III breast cancer diagnosed 2000-2012 and prescribed hormonal therapy were identified from the National Cancer Registry Ireland (NCRI) and linked to pharmacy claims data from Ireland's Primary Care Reimbursement Services (PCRS). Non-persistence was defined as a treatment gap of ≥180 days within 5 years of initiation. Seventeen demographic, clinical and treatment-related risk factors, identified from a systematic review, were abstracted from the NCRI-PCRS dataset. Multivariate binomial models were used to estimate relative risks (RR) and risk differences (RD) for associations between risk factors and non-persistence. Calibration and discriminative performance of the models were assessed. The analysis was repeated for early non-persistence (<1 year of initiation). Within 5 years of treatment initiation 680 women (19.9%) were non-persistent. Women aged <50 years (adjusted RR 1.41, 95% CI 1.16-1.70) and those prescribed antidepressants (RR 1.22, 95% CI 1.04-1.45) had increased risk of non-persistence. Married women (RR 0.82 95% CI 0.71-0.94) and those with prior medication use (RR 0.62 95% CI 0.51-0.75) had reduced risk of non-persistence. The area under the receiver-operating characteristic (ROC) curve for non-persistence was 0.61. Findings were similar for early non-persistence. The risk prediction model did not discriminate well between women at higher and lower risk of non-persistence at treatment initiation. Future studies should consider other factors, such as psychological characteristics and experience of side-effects.

Deep semantic encoding of verbal stimuli can aid in later successful retrieval of those stimuli from long-term episodic memory. Evidence from numerous neuropsychological and neuroimaging experiments demonstrate regions in left prefrontal cortex, including left dorsolateral prefrontal cortex (DLPFC), are important for processes related to encoding. Here, we investigated the relationship between left DLPFC activity during encoding and successful subsequent memory with transcranial magnetic stimulation (TMS). In a pair of experiments using a 2-session within-subjects design, we stimulated either left DLPFC or a control region (Vertex) with a single 2-s train of short theta burst stimulation (sTBS) during a semantic encoding task and then gave participants a recognition memory test. We found that subsequent memory was enhanced on the day left DLPFC was stimulated, relative to the day Vertex was stimulated, and that DLPFC stimulation also increased participants’ confidence in their decisions during the recognition task. We also explored the time course of how long the effects of sTBS persisted. Our data suggest 2 s of sTBS to left DLPFC is capable of enhancing subsequent memory for items encoded up to 15 s following stimulation. Collectively, these data demonstrate sTBS is capable of enhancing long-term memory and provide evidence that TBS protocols are a potentially powerful tool for modulating cognitive function.

Early detection and prevention of cardiac dysfunction is an important goal in the management of hypertensive patients. In this study, Doppler echocardiography was used to evaluate the pattern of left ventricular diastolic filling in 38 subjects: 18 treated hypertensive patients (blood pressure 141 +/- 17/83 +/- 10 mm Hg, mean +/- SD) without other coronary risk factors and 20 risk-free normotensive subjects of similar age (47 +/- 10 and 49 +/- 13 years, respectively). Peak velocity of late left ventricular filling due to the atrial contraction was greater in hypertensive compared with normotensive subjects (69 +/- 14 versus 52 +/- 13 cm/s; p less than 0.001). Peak velocity of late filling was significantly greater in hypertensive versus normotensive subjects in those aged 50 years or younger and those older than age 50 (65 +/- 12 versus 50 +/- 11; p less than 0.01 and 75 +/- 15 versus 56 +/- 15 cm/s; p less than 0.05, respectively). In hypertensive subjects, peak velocity of late filling did not correlate with routine indexes of hypertensive heart disease (including posterior wall thickness and left ventricular mass), systolic and diastolic blood pressure or duration of hypertension. These results indicate that increased velocity of late left ventricular filling may be independent of left ventricular hypertrophy and persist despite effective blood pressure control.

Renal arteriovenous fistula (RAVF) is a comparatively rare malformation. Here, we report a case of ruptured RAVF that was successfully treated by catheter embolization. An 89-year-old female was transferred to our institution with massive gross hematuria in March 2011. Plain abdominal computed tomography (CT) revealed dilated left renal pelvis with high-density contents. Hematoma was suspected. Subsequent plain abdominal magnetic resonance imaging revealed left hydronephrosis and blood retention in the dilated left renal pelvis. No renal or ureteral cancer was evident. Hematuria was conservatively treated using hemostatic agents but hematuria persisted. Repeated urinary cytology revealed no malignant cells. On day 9, the patient went into septic and/or hemorrhagic shock. Fluid and catecholamine infusion, blood transfusion, and antibacterial drugs were rapidly initiated, and the patient's general condition gradually improved. Contrast-enhanced abdominal CT revealed marked expansion of the hematoma in the renal pelvis and microaneurysms in the segmental arteries of the left kidney. Inflammation improved, and a left double-J stent was inserted. Selective renal angiography revealed RAVF with microaneurysms in the left segmental arteries; therefore, catheter embolization using metallic coils was performed, which resolved hematuria. We report a case of ruptured renal arteriovenous malformation, which was successfully treated by catheter embolization.

Overproduction of thyroid hormones leads to structural as well as functional cardiac changes. Conventional echocardiography but also recently developed sophisticated two-dimensional echocardiography speckle (2D-STE) tracking allow elaborate evaluation of these changes. Our purpose was to investigate the effects of thyroid hormones overproduction on the heart in patients with Graves' disease and changes that occur after 6 months thyrostatic therapy. We conducted a prospective, case-control study of 6 months duration. Full echocardiographic assessment at diagnosis and after 6 months of thyrostatic therapy were performed in 44 patients with Graves' disease, aged 37.6 ± 9.1 years. Additionally, 43 euthyroid controls were studied for the same time period. Left ventricular end diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) were higher in the patient group while triscupid annular plane systolic excursion (TAPSE) was lower in the patient group. Moreover, left ventricular (LV) mass index and left atrium (LA) volume index were higher in the Graves' disease group. Diastolic impairment as assessed with conventional echocardiography including tissue Doppler was present in the patient group (E/A ratio 0.87 ± 0.10,). 2D-STE analysis, revealed an increase in the strain rate at the isovolumic relaxation time (SRIVRT, 0.310 ± 0.07 patients versus 0.298 ± 0.09 s -1 controls). Improvement in diastolic and right systolic function as well as in left ventricular structural parameters was observed after restoration of euthyroidism (E/A ratio from 0.87 ± 0.10 versus 0.9 ± 0.08, p < 0.05). Patients with newly diagnosed Graves' showed an improvement in diastolic function, right systolic function and structural parameters after 6 months of thyrostatic treatment.

Left ventricular diastolic dysfunction (LVDD) is common in sickle cell anaemia (SCA). Left atrial (LA) size is widely used as an index of LVDD; however, LA enlargement in SCA might also be due to chronic volume overload. To investigate whether LA size can be used to diagnose LVDD in SCA. One hundred and twenty-seven adults with stable SCA underwent echocardiographic assessment. LA volume was measured by the area-length method and indexed to body surface area (LAVi). Left ventricular (LV) filling pressures were assessed using the ratio of early peak diastolic velocities of mitral inflow and septal annular mitral plane (E/e'). Using mitral inflow profile and E/e', LV diastolic function was classified as normal or abnormal. LAVi>28mL/m(2) was used as the threshold to define LA enlargement. The mean age was 28.6±8.5years; there were 83 women. Mean LAVi was 48.3±11.1mL/m(2) and 124 (98%) patients had LA dilatation. In multivariable analysis, age, haemoglobin concentration and LV end-diastolic volume index were independent determinants of LAVi (R(2)=0.51; P<0.0001). E/e' was not linked to LAVi (P=0.43). Twenty patients had LVDD; when compared with patients without LVDD, they had a similar LAVi (52.2±14.7 and 47.5±10.2mL/m(2), respectively; P=0.29). Receiver operating characteristics curve analysis showed that LAVi could not be used to diagnose LVDD (area under curve=0.58; P=0.36). LA enlargement is common in SCA but appears not to be linked to LVDD. LAVi in this population is related to age, haemoglobin concentration and LV morphology. Copyright © 2014 Elsevier Masson SAS.

Patients with vascular Ehlers-Danlos syndrome (EDS) are susceptible to significant vascular complications, such as aortic and visceral arterial ruptures, aneurysms, and dissection. We describe a case of repeated bleeding in a 57-year-old woman and a case of sudden onset of artery dissection in her daughter, both of whom were previously diagnosed with vascular EDS and managed at our institution. A 57-year-old woman was admitted to our emergency department due to sudden onset of left low back pain. Her past history included vascular EDS. An urgent abdominal computed tomography (CT) scan revealed a left-sided retroperitoneal hematoma and left external iliac artery dissection. Stent graft repair was performed. Five hours postoperatively, cardiac arrest occurred and resuscitation attempts failed. The 32-year-old daughter with genetically diagnosed vascular EDS was notified of the death of her mother during the customary end-of-life conference. Six hours after her mother's death, she was admitted to our emergency department due to sudden onset of left low back pain. On examination, she was not in hypovolemic shock, and weak pulses were palpable in the bilateral dorsalis pedis. An urgent abdominal CT scan revealed a right-sided retroperitoneal hematoma around the right external iliac artery and left external iliac artery dissection. She was admitted to the intensive care unit and underwent conservative therapy consisting of bed rest and antihypertensive therapy with nicardipine. She developed no further vascular complications requiring surgical intervention and was discharged on the 21st hospital day. Vascular rupture can be fatal in patients with vascular EDS. This report underscores the importance of strategic management of vascular complications to prevent rupture, and the importance of psychological care for the bereaved family given the hereditary nature of vascular EDS.

Many thoracic aortic aneurysms are discovered incidentally, and most develop without symptoms. Symptoms are usually due to sudden expansion of the aneurysm, which can cause a vague pain in the back, or sometimes a sharp pain that may denote the presence of impending rupture. Other symptoms are related to pressure on adjacent structures, such as pressure on the bronchus that can cause respiratory distress, or pressure on the laryngeal nerve causing vocal hoarseness. Pressure on the esophagus can cause difficulty in swallowing. Currently, open surgery and thoracic endovascular aneurysm repair (TEVAR) are the choices of treatment for descending thoracic aneurysms (DTA). The decision to intervene on a DTA depends on its size, location, rate of growth and symptoms, and the overall medical condition of the patient. The indications for TEVAR should not differ from those for open surgery and typically include aneurysms larger than 6 cm in diameter. Saccular and symptomatic aneurysms are often repaired at a smaller size. It is also suggested that aneurysms with a growth rate more than 1 cm per year, or 0.5 cm in 6 months should be considered for early repair.Despite the close proximity of the aorta and left main bronchus, atelectasis caused by thoracic aortic aneurysms is rare. We review the case report of a patient with concomitant persistent left pulmonary atelectasis causing acute respiratory distress due to complete compression of the left main bronchus after TEVAR of a descending thoracic aortic aneurysm.

Significant efficacy and well safety of apatinib combined with radiotherapy in NSCLC

Abstract Rationale: The outcomes of locally advanced non-small cell lung cancer (NSCLC) remain poor, in particular, the frail elderly patients cannot tolerate chemotherapy. The new efficient, safe, and more specific treatments are needed. Radiation combined with targeted therapy is the focus of research in recent years. Apatinib is highly selective tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2, studies have revealed that apatinib inhibit the growth of solid tumors including NSCLC. However, there is no report to evaluate its efficacy and safety in combined with radiotherapy for the advanced NSCLC. Our original research about to explore the use of apatinib combined with radiotherapy in treatment of NSCLC and its side effects are as follows. Patient concerns: Patient 1, man, 78-year old, admitted to hospital, due to “thoracalgia and dyspnea for 1 month.” Chest and abdomen computed tomography (CT) scan showed that there was a huge mass at the left upper lobe and multiple lymph nodes metastasis in mediastinum and left hilus pulmonis, the diagnosis was left lung squamous cell carcinoma, however, the mass was huge and age of patient was elder, post chemotherapy the mass were bigger and more severe. Patient 2, man, 61-year old, the diagnosis was squamous carcinoma on left upper lobe with right mediastinum lymph notes metastases recrudescence post chemoradiotherapy. Diagnoses: Case 1 was diagnosed left lung huge squamous cell carcinoma and case 2 was left lung squamous carcinoma, the primary lesion and right mediastinum lymph notes metastases recrudescence after radiochemotherapy. Interventions: Both patients who received local radiation therapy and concurrent apatinib. Apatinib 250 mg once daily in combination with thoracic radiotherapy (2 Gy/d, 5 fractions/wk) followed by Apatinib Maintenance Therapy. Outcomes: Favorable oncologic outcomes were achieved in the 2 cases after the treatment. The common side effects of apatinib were hypertension and hand-foot syndrome; however, the toxicity of was controllable and tolerable, no dyspnea, no hemoptysis, no thoracalgia. Lessons: Apatinib combined with thoracic radiotherapy, may be an option for recurring or advanced NSCLC. But that still warrants further investigation in the prospective study. PMID:29390380

Recent studies have demonstrated a role for calcium channel blocking agents in the treatment of persistent hyperinsulinemic hypoglycemia of newborns. We report a newborn infant with persistent hyperinsulinemic hypoglycemia whom we successfully treated with oral nifedipine alone after surgical therapies. A 4-day-old male infant was referred with intractable hypoglycemia and seziures. Normoglycaemia could be maintained only by the intravenous infusion of glucose at a rate of 20 mg/kg per minute. Persistent hyperinsulinemic hypoglycemia of newborn was diagnosed from an inappropriately raised plasma insulin concentration (44 mU/L) at the time of hypoglycemia. Medical treatments led to only a mild reduction in the intravenous glucose requirement; an 85-90% pancreatectomy was performed and histological "diffuse nesidioblastosis" was confirmed. However, despite all the medical treatments after the first pancreatectomy, the hyperinsulinemic hypoglycemia persisted and a second 95% pancreatectomy was performed. After the second pancreatectomy, persistent hyperinsulinemic hypoglycemia was treated with somatostatin and diazoxide, but led to no reduction in the intravenous glucose requirement. We report the case of an infant who had persistent hypoglycemia after two subtotal pancreatic resections but subsequently became normoglycemic on treatment with nifedipine (2 mg/kg per day). The patient was discharged home on oral nifedipine. Calcium channel blocking agents cuold be used with efficacy and safety in recurrent persistent hyperinsulinemic hypoglycemia.

A Search for FRB 121102-like Persistent Radio-luminous Sources—Candidates and Implications for the FRB Rate and Searches

The localization of the repeating fast radio burst (FRB), FRB 121102, suggests that it is associated with a persistent radio-luminous compact source in the FRB host galaxy. Using the FIRST radio catalog, I present a search for luminous persistent sources in nearby galaxies, with radio luminosities > 10 % of the FRB 121102 persistent source luminosity. The galaxy sample contains about 30% of the total galaxy g-band luminosity within < 108 Mpc, in a footprint of 10,600 deg2. After rejecting sources likely due to active galactic nuclei activity or background sources, I am left with 11 candidates that are presumably associated with galactic disks or star-formation regions. At least some of these candidates are likely to be due to chance alignment. In addition, I find 85 sources within 1\\prime\\prime of galactic nuclei. Assuming that the radio persistent sources are not related to galactic nuclei and that they follow the galaxy g-band light, the 11 sources imply a 95% confidence upper limit on the space density of luminous persistent sources of ≲ 5× {10}-5 Mpc-3, and that at any given time only a small fraction of galaxies host a radio-luminous persistent source (≲ {10}-3 {L}* -1). Assuming a persistent source lifetime of 100 years, this implies a birth rate of ≲ 5× {10}-7 yr-1 Mpc-3. Given the FRB volumetric rate, and assuming that all FRBs repeat and are associated with persistent radio sources, this sets a lower limit on the rate of FRB events per persistent source of ≳ 0.8 yr-1. I argue that these 11 candidates are good targets for FRB searches and I estimate the FRB event rate from these candidates.

Visual disturbances in migraineurs, such as visual aura, are typically episodic, that is, associated with the headache attack, and overlaid by head pain and other symptoms that impact the patient. In some patients, however, visual symptoms are dominant due to frequency (migraine aura status), duration (persistent migraine aura and other persistent positive visual phenomena), or complexity (visual snow syndrome). These syndromes are more rare and challenging to classify in clinical practice resulting in a lack of systematic studies on pathophysiology and treatment. We aim at describing clinical features and pathophysiological concepts of typical migraine aura with a focus on cortical spreading depression and differentiation from non-typical migraine aura. Additionally, we discuss nomenclature and the specifics of migraine aura status, persistent migraine aura, persistent positive visual phenomena, visual snow, and other migrainous visual disturbances. The term migraine with prolonged aura might be a useful bridge between typical aura and persistent aura. Further studies would be necessary to assess whether a return of the classification category eventually helps diagnosing or treating patients more effectively. A practical approach is presented to help the treating physician to assign the correct diagnosis and to choose a medication for treatment that has been successful in case reports of these rare but disabling conditions. © 2016 American Headache Society.

Human T-cell leukemia virus type 1 (HTLV-1) is the causative agent of adult T-cell leukemia-lymphoma (ATL), which is difficult to cure. In Japan, a nationwide HTLV-1 screening test in pregnant women has been recommended since 2011. A 30-year-old woman was diagnosed as being an HTLV-1 carrier in her previous pregnancy. During the current pregnancy, she had persistent fever and cough. Although she had treatment with antibiotics, peripheral white blood cell count remained high, with an abnormal lymphocyte count. Given that she was an HTLV-1 carrier, she was diagnosed with unfavorable chronic ATL (aggressive ATL) at 12 weeks gestation. After pregnancy termination, her ATL status became favorable chronic ATL (indolent ATL). Therefore, watchful waiting was performed until disease progression. This is the first case report of chronic ATL in early pregnancy, in a woman already diagnosed as an HTLV-1 carrier on screening test. © 2015 Japan Society of Obstetrics and Gynecology.

Multidetector-row computed tomography of thoracic aortic anomalies in dogs and cats: Patent ductus arteriosus and vascular rings

PubMed Central

2011-01-01

Background Diagnosis of extracardiac intrathoracic vascular anomalies is of clinical importance, but remains challenging. Traditional imaging modalities, such as radiography, echocardiography, and angiography, are inherently limited by the difficulties of a 2-dimensional approach to a 3-dimensional object. We postulated that accurate characterization of malformations of the aorta would benefit from 3-dimensional assessment. Therefore, multidetector-row computed tomography (MDCT) was chosen as a 3-dimensional, new, and noninvasive imaging technique. The purpose of this study was to evaluate patients with 2 common diseases of the intrathoracic aorta, either patent ductus arteriosus or vascular ring anomaly, by contrast-enhanced 64-row computed tomography. Results Electrocardiography (ECG)-gated and thoracic nongated MDCT images were reviewed in identified cases of either a patent ductus arteriosus or vascular ring anomaly. Ductal size and morphology were determined in 6 dogs that underwent ECG-gated MDCT. Vascular ring anomalies were characterized in 7 dogs and 3 cats by ECG-gated MDCT or by a nongated thoracic standard protocol. Cardiac ECG-gated MDCT clearly displayed the morphology, length, and caliber of the patent ductus arteriosus in 6 affected dogs. Persistent right aortic arch was identified in 10 animals, 8 of which showed a coexisting aberrant left subclavian artery. A mild dilation of the proximal portion of the aberrant subclavian artery near its origin of the aorta was present in 4 dogs, and a diverticulum analogous to the human Kommerell's diverticulum was present in 2 cats. Conclusions Contrast-enhanced MDCT imaging of thoracic anomalies gives valuable information about the exact aortic arch configuration. Furthermore, MDCT was able to characterize the vascular branching patterns in dogs and cats with a persistent right aortic arch and the morphology and size of the patent ductus arteriosus in affected dogs. This additional information can be of help with regard to improved diagnoses of thoracic anomalies and the planning of surgical interventions. PMID:21943366

Persistent Müllerian duct syndrome (PMDS) is a pseudohermaphroditism in males characterized by the presence of Müllerian duct derivatives. As PMDS dogs often lack clinical symptoms, a molecular diagnosis is essential to identify the syndrome in these animals. In this study, a new molecular method using DNA mismatch-specific Surveyor nuclease was developed. The Surveyor nuclease assay identified the AMHR2 mutation that produced PMDS in a Miniature Schnauzer as accurately as that obtained by using the conventional method based on restriction digestion. As an alternative to the current molecular diagnostic method, the new method may result in increased accuracy when detecting PMDS.

It is well established that HIV patients are at high risk of opportunistic infections (OI), like the ones caused by Pneumocystis jirovecii, a worldwide pathogen implicated in interstitial pneumonia (PcP). We present a case of a newly diagnosed HIV-1 patient with multiple OI, including a persistent form of PcP, an invasive aspergillosis (IA), cytomegalovirus and Mycobacterium xenopi lung infection. We describe the combination of laboratorial screening, surgery and antimicrobial therapy that were crucial for patient recovery. Copyright © 2012 Sociedade Portuguesa de Pneumologia.
