The medical and surgical complications of percutaneous nephrolithotomy (PCNL) are well-known, including deep venous thrombosis. Ovarian vein thrombosis (OVT) is a rare, but potentially serious type of venous thrombosis that has not previously been reported as a complication of PCNL or ureteral stent placement. We report a case of OVT associated with ureteral stenting following a tubeless PCNL. This complication was successfully managed conservatively without any short- or long-term sequelae. PMID:27695586

This study was set up to determine the long term ocular and systemic sequelae in patients with severe congenital toxoplasmosis. Cross sectional and retrospective study of 17 patients with severe congenital toxoplasmosis. In addition to chorioretinitis (100%), the most common abnormal ocular features were optic nerve atrophy (83%), visual acuity of less than 0.1 (85%), strabismus, and microphthalmos. In 50% of cases we observed iridic abnormalities and about 40% developed a cataract. Overt endocrinological disease, diagnosed in five of 15 patients, included panhypopituitarism (n = 2), gonadal failure with dwarfism (n = 1), precocious puberty with dwarfism and thyroid deficiency (n = 1), and diabetes mellitus and thyroid deficiency (n = 1). The observed endocrinological involvement was associated in all cases with obstructive hydrocephalus with a dilated third ventricle and optic nerve atrophy. The recognition of long term ocular, neurological, and endocrinological sequelae of congenital toxoplasmosis is important for medical management of these severely handicapped patients.

Long Term Sequelae of Pediatric Craniopharyngioma – Literature Review and 20 Years of Experience

Cohen, Michal; Guger, Sharon; Hamilton, Jill

2011-01-01

Craniopharyngioma are rare histologically benign brain tumors that develop in the pituitary–hypothalamic area. They may invade nearby anatomical structures causing significant rates of neurological, neurocognitive, and endocrinological complications including remarkable hypothalamic damage. Information regarding long term implications of the tumors and treatment in the pediatric population is accumulating, and treatment goals appear to be changing accordingly. In this review we aim to present data regarding long term complications of craniopharyngioma in children and adolescents and our experience from a large tertiary center. Hypothalamic dysfunction was noted to be the most significant complication, adversely affecting quality of life in survivors. Obesity, fatigue, and sleep disorders are the most notable manifestations of this dysfunction, and treatment is extremely difficult. Changes in management in recent years show a potential for improved long term outcomes; we found a trend toward less aggressive surgical management and increasing use of adjuvant treatment, accompanied by a decrease in complication rates.

The purpose of the study was to present a pictorial review of the long-term sequelae of acute pancreatitis on CT imaging as these findings can cause diagnostic confusion in the absence of a proper clinical history and/or prior CT imaging. We retrospectively identified 81 patients who had an episode of acute pancreatitis with diagnostic findings on CT and also underwent one or more follow-up CT scans at least 1 month beyond the acute episode. The residual findings on all follow-up CT scans were tabulated, including the time interval since the initial bout of acute pancreatitis. Residual inflammatory changes were present in 19.8% of cases, with a median time period lasting 86 days since the initial episode of acute pancreatitis. Residual fluid collections were seen in 27.2% and persisted for a median of 132 days. Three patients had residual solid-appearing inflammatory masses, which could be mistaken for neoplasms. Other long-term sequelae were also tabulated, including pancreatic ductal dilatation, pancreatic atrophy, new or increased pancreatic calcifications, biliary tract dilatation, central portal venous occlusion, and pseudoaneurysm formation. These residual findings and long-term complications are presented as a pictorial essay. Recognizing the spectrum of residual findings of acute pancreatitis, some of which can be long term, is important in the correct interpretation of a pancreatic CT. These findings can mimic acute pancreatitis or a pancreatic/peripancreatic neoplasm and often cause diagnostic confusion, especially in the absence of prior CT imaging.

Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. Its etiology remains unknown, and treatment is largely symptom based and empirical. PCOS has the potential to cause substantial metabolic sequelae, including an increased risk of diabetes and cardiovascular disease, and these factors should be considered when determining long-term treatment. The purpose of this document is to examine the best available evidence for the diagnosis and clinical management of PCOS.

ABSTRACT The role of tuberculosis as a public health care priority and the availability of diagnostic tools to evaluate functional status (spirometry, plethysmography, and DLCO determination), arterial blood gases, capacity to perform exercise, lesions (chest X-ray and CT), and quality of life justify the effort to consider what needs to be done when patients have completed their treatment. To our knowledge, no review has ever evaluated this topic in a comprehensive manner. Our objective was to review the available evidence on this topic and draw conclusions regarding the future role of the "post-tuberculosis treatment" phase, which will potentially affect several million cases every year. We carried out a non-systematic literature review based on a PubMed search using specific keywords (various combinations of the terms "tuberculosis", "rehabilitation", "multidrug-resistant tuberculosis", "pulmonary disease", "obstructive lung disease", and "lung volume measurements"). The reference lists of the most important studies were retrieved in order to improve the sensitivity of the search. Manuscripts written in English, Spanish, and Russian were selected. The main areas of interest were tuberculosis sequelae following tuberculosis diagnosis and treatment; "destroyed lung"; functional evaluation of sequelae; pulmonary rehabilitation interventions (physiotherapy, long-term oxygen therapy, and ventilation); and multidrug-resistant tuberculosis.The evidence found suggests that tuberculosis is definitively responsible for functional sequelae, primarily causing an obstructive pattern on spirometry (but also restrictive and mixed patterns), and that there is a rationale for pulmonary rehabilitation. We also provide a list of variables that should be discussed in future studies on pulmonary rehabilitation in patients with post-tuberculosis sequelae. PMID:27812638

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is an uncommon, life-threatening drug reaction. The basic findings are skin rash, multiorgan involvement, and eosinophilia. Most of the aromatic anticonvulsants, such as phenytoin, phenobarbital and carbamazepine can induce DRESS. Herein we report a 14-year-old patient with DRESS syndrome related to carbamazepine use. The patient presented with signs of involvement of the skin, lungs, liver, and microscopic hematuria. Carbamazepine treatment was discontinued; antihistamines and steroids were started. Hyperglycemia, commencing on the first dose of the steroid given, persisted even after the discontinuation of steroids and improvement of other signs. There were no signs of pancreatitis or type 1 diabetes clinically in laboratory tests. Her blood glucose levels were regulated at first with insulin and later with metformin. Within 1 year of follow-up, still regulated with oral antidiabetics, she has been diagnosed with type 2 diabetes. Formerly, long-term sequelae related to “drug rash with eosinophilia and systemic symptoms syndrome” such as hepatic and renal failure, type 1 diabetes mellitus, Grave's disease, autoimmune hemolytic anemia, and lupus have also been reported. However, up to date, no cases with type 2 diabetes have been reported as long-term sequelae. To our knowledge, this is the first case in the literature presenting with type 2 diabetes as long-term sequelae. PMID:26862317

Post-infectious sequelae of travelers' diarrhea.

PubMed

Connor, Bradley A; Riddle, Mark S

2013-01-01

Travelers' diarrhea (TD) has generally been considered a self-limited disorder which resolves more quickly with expeditious and appropriate antibiotic therapy given bacteria are the most frequently identified cause. However, epidemiological, clinical, and basic science evidence identifying a number of chronic health conditions related to these infections has recently emerged which challenges this current paradigm. These include serious and potentially disabling enteric and extra-intestinal long-term complications. Among these are rheumatologic, neurologic, gastrointestinal, renal, and endocrine disorders. This review aims to examine and summarize the current literature pertaining to three of these post-infectious disorders: reactive arthritis, Guillain-Barré syndrome, and post-infectious irritable bowel syndrome and the relationship of these conditions to diarrhea associated with travel as well as to diarrhea associated with gastroenteritis which may not be specifically travel related but relevant by shared microbial pathogens. It is hoped this review will allow clinicians who see travelers to be aware of these post-infectious sequelae thus adding to our body of knowledge in travel medicine. Data for this article were identified by searches of PubMed and MEDLINE, and references from relevant articles using search terms "travelers' diarrhea" "reactive arthritis" "Guillain-Barré syndrome" "Post-Infectious Irritable Bowel Syndrome." Abstracts were included when related to previously published work. A review of the published literature reveals that potential consequences of travelers' diarrhea may extend beyond the acute illness and these post-infectious complications may be more common than currently recognized. In addition since TD is such a common occurrence it would be helpful to be able to identify those who might be at greater risk of post-infectious sequelae in order to target more aggressive prophylactic or therapeutic approaches to such individuals. It is hoped this review will allow clinicians who see travelers to be aware of these post-infectious sequelae thus adding to our body of knowledge in travel medicine. © 2013 International Society of Travel Medicine.

Testicular Cancer Survivorship: Research Strategies and Recommendations

Testicular cancer represents the most curable solid tumor, with a 10-year survival rate of more than 95%. Given the young average age at diagnosis, it is estimated that effective treatment approaches, in particular, platinum-based chemotherapy, have resulted in an average gain of several decades of life. This success, however, is offset by the emergence of considerable long-term morbidity, including second malignant neoplasms, cardiovascular disease, neurotoxicity, nephrotoxicity, pulmonary toxicity, hypogonadism, decreased fertility, and psychosocial problems. Data on underlying genetic or molecular factors that might identify those patients at highest risk for late sequelae are sparse. Genome-wide association studies and other translational molecular approaches now provide opportunities to identify testicular cancer survivors at greatest risk for therapy-related complications to develop evidence-based long-term follow-up guidelines and interventional strategies. We review research priorities identified during an international workshop devoted to testicular cancer survivors. Recommendations include 1) institution of lifelong follow-up of testicular cancer survivors within a large cohort setting to ascertain risks of emerging toxicities and the evolution of known late sequelae, 2) development of comprehensive risk prediction models that include treatment factors and genetic modifiers of late sequelae, 3) elucidation of the effect(s) of decades-long exposure to low serum levels of platinum, 4) assessment of the overall burden of medical and psychosocial morbidity, and 5) the eventual formulation of evidence-based long-term follow-up guidelines and interventions. Just as testicular cancer once served as the paradigm of a curable malignancy, comprehensive follow-up studies of testicular cancer survivors can pioneer new methodologies in survivorship research for all adult-onset cancer.

Many pediatric urologic disorders have sequelae that may affect patients well into adulthood. Despite adequate treatment, many patients are at risk for progressive urologic deterioration years after surgical reconstruction. While many pediatric urologists follow their patients years after surgery, screening for late complications is a shared responsibility with primary care providers. This article discusses potential late complications and appropriate follow-up for patients who have a history of ureteral reimplantation, pyeloplasty, hypospadias repair, posterior urethral valve ablation, and intestinal interposition.

To compare how parents and physicians value potential clinical outcomes in young children who have a fever but no focus of bacterial infection. Cross-sectional study of 100 parents of well children aged 3 to 24 months, 61 parents of febrile children aged 3 to 24 months, and 56 attending staff physicians working in a children's hospital emergency department. A pretested visual analog scale was used to assess values on a 0-to-1 scale (where 0 is the value of the worst possible outcome, and 1 is the value for the best) for 22 scenarios, grouped in three categories according to severity. Based on the three or four common attributes comprising the scenarios in a given group, each respondent's value function was estimated statistically based on multiattribute utility theory. For outcomes in group 1 (rapidly resolving viral infection with one or more diagnostic tests), no significant group differences were observed. For outcomes in groups 2 (acute infections without long-term sequelae) and 3 (long-term sequelae of urinary tract infection or bacterial meningitis), parents of well children and parents of febrile children had values that were similar to each other but significantly lower than physicians' values for pneumonia with delayed diagnosis, false-positive diagnosis of urinary tract infection, viral meningitis, and unilateral hearing loss. For bacterial meningitis with or without delay, however, the reverse pattern was observed; physicians' values were lower than parents'. In arriving at their judgment for group 2 and 3 scenarios, parents gave significantly greater weight to attributes involving the pain and discomfort of diagnostic tests and to diagnostic error, whereas physicians gave significantly greater weight to attributes involving both short- and long-term morbidity and long-term worry and inconvenience. Parents were significantly more likely to be risk-seeking in the way they weighted the attributes comprising group 2 and 3 scenarios than physicians, ie, they were more willing to risk rare but severe morbidity to avoid the short-term adverse effects of testing. Parents and physicians show fundamental value differences concerning diagnostic testing, diagnostic error, and short- and long-term morbidity; these differences have important implications for diagnostic decision making in the young febrile child.

Neurological sequelae of bacterial meningitis.

2016-07-01

We reported on occurrence and impact of neurological sequelae after bacterial meningitis. We reviewed occurrence of neurological sequelae in children and adults after pneumococcal and meningococcal meningitis. Most frequently reported sequelae are focal neurological deficits, hearing loss, cognitive impairment and epilepsy. Adults with pneumococcal meningitis have the highest risk of developing focal neurological deficits, which are most commonly caused by cerebral infarction, but can also be due to cerebritis, subdural empyema, cerebral abscess or intracerebral bleeding. Focal deficits may improve during clinical course and even after discharge, but a proportion of patients will have persisting focal neurological deficits that often interfere in patient's daily life. Hearing loss occurs in a high proportion of patients with pneumococcal meningitis and has been associated with co-existing otitis. Children and adults recovering from bacterial meningitis without apparent neurological deficits are at risk for long-term cognitive deficits. Early identification of neurological sequelae is important for children to prevent additional developmental delay, and for adults to achieve successful return in society after the disease. Neurological sequelae occur in a substantial amount of patients following bacterial meningitis. Most frequently reported sequelae are focal neurological deficits, hearing loss, cognitive impairment and epilepsy. Copyright © 2016 The British Infection Association. Published by Elsevier Ltd.

Long-term sequelae of critical illness: memories and health-related quality of life.

Hough, Catherine Lee; Curtis, J Randall

2005-04-01

Impaired health-related quality of life after critical illness has been demonstrated in a number of studies. It is not clear exactly how or why critical illness and intensive care lead to impaired health status, but understanding this association is an important step to improving long-term outcomes of the critically ill. There is growing evidence that neuro-psychological symptoms play a significant role in this impairment and that management of patients in the intensive care unit (ICU) may influence these symptoms. This commentary examines a recent study and places this study in the context of previous studies suggesting that both amnesia and persisting nightmares of the ICU experience are associated with impaired quality of life. Further research is needed if we are effectively to understand, prevent and treat the negative sequelae of critical illness.

The aim of the study was to describe the epidemiology and clinical characteristic of children hospitalized with pneumonia complicated by lung abscess, as well as to evaluate the long-term sequelae of the disease. A retrospective review of medical records of all patients treated for pulmonary abscess in two tertiary centers was undertaken. Pulmonary function tests and lung ultrasound were performed at a follow-up. During the study period, 5151 children with pneumonia were admitted, and 49 (0.95%) cases were complicated with lung abscess. In 38 (77.5%) patients, lung abscess was treated solely with antibiotics, and in nine cases (16.3%) surgically. In 21 (51.21%) children complete radiological regression was documented. The mean time for radiological abnormalities regression was 84.14 ± 51.57 days, regardless of the treatment mode. Fifteen patients were followed up at 61.6 ± 28.3 months after discharge. Lung ultrasound revealed minor residual abnormalities: pleural thickening, subpleural consolidations and line B artefacts in 11 (73.3%) children. Pulmonary function tests results were abnormal in eight (53.3%) patients, the most frequent abnormality being hyperinflation. We did not find a restrictive disorder in any of the children. There were no deaths in our study. Lung abscess is a rare but severe complication of pneumonia in children. Most children recover uneventfully with no significant long-term pulmonary sequelae.

Dramatic advances in neonatal medicine over recent decades have resulted in decreased mortality and morbidity rates for extremely low birth weight infants. However, the survival of these infants is associated with short- and long-term morbidity, including severe intraventricular hemorrhage, periventricular leukomalacia, nosocomial infection and necrotizing enterocolitis, bronchopulmonary dysplasia, retinopathy of prematurity and adverse long-term neurodevelopmental sequelae. This article reviewed the latest advances in the medical care for extremely low birth weight infants including survival rate, ethical issues and short- and long-term morbidity, domestically and abroad.

Tennyson, Heath C; Mair, Eric A

2004-03-01

In light of recent terrorist events and the potential threat of smallpox as a biological agent, we present information concerning smallpox to better inform the otolaryngologist concerning this disease and its prevention. We performed a review of the smallpox and smallpox vaccination literature over the past 200 years using MEDLINE, PREMEDLINE, Centers for Disease Control and Prevention Internet site, World Health Organization Internet site, and references found in previous publications not found in MEDLINE or PREMEDLINE. Our search focused on the pathogenesis, clinical presentation, course, unique manifestations in the head and neck, diagnosis, and treatment of smallpox, as well as the method of smallpox vaccination, vaccination contraindications, and complications. Smallpox is a viral disease with a high mortality rate. Its clinical course, manifestations, and methods of prevention are carefully analyzed in light of otolaryngology practice. Smallpox manifestations in the head and neck often presented as acute airway obstruction and also as long-term sequelae such as ectropion, nasal vestibular stenosis, conductive hearing loss, and blindness. Most chronic sequelae involve the head and neck. Smallpox vaccination is effective but not without potential serious risks.

The aim of this study was to know the epidemiology of burns in teenagers. Burn patients over 11 years old admitted in our Institution in the last 10 years were included. Etiology, burn size, hospital stay, quirurgical interventions and long term sequelae were registered. One thousand and eight patients were admitted, 89 were over 11 years (8.8%), 70.7% were boys and 29.3% girls. Fire was the principal agent in 58 cases (65.1%), due to fireworks in 13 (22.4%), alcohol in 7 (12%), explosion of flammable containers (spray) in 4 (6.8%) and gasoline in 3 (5.2%). Fireworks injuries and spray explosions affected face and hand in 88% cases. The median hospital stay was 8 days after admission (1 to 90). 83.1% required surgical treatment with mean of 1.8 +/- 1.4 interventions and 21.3% had long-term sequelaes that required at least one surgical intervention. Fire is the main cause of burns in adolescents. Fireworks injuries represented a quarter of that lesions, and highlights paint spray explosions as new causative agents. Considering the high morbidity in this age group, with permanent functional and aesthetic sequelae, prevention campaigns are needed to reduce such accidents.

Hand, foot and mouth disease (HFMD) caused by enterovirus A71 (EV-A71) is associated with acute neurological disease in children. This study aimed to estimate the burden of long-term sequelae and death following severe HFMD. This systematic review and meta-analysis pooled all reports from English and Chinese databases including MEDLINE and Wangfang on outbreaks of clinically diagnosed HFMD and/or laboratory-confirmed EV-A71 with at least 7 days' follow-up published between 1st January 1966 and 19th October 2015. Two independent reviewers assessed the literature. We used a random effects meta-analysis to estimate cumulative incidence of neurological sequelae or death. Studies were assessed for methodological and reporting quality. PROSPERO registration number: 10.15124/CRD42015021981. 43 studies were included in the review, and 599 children from 9 studies were included in the primary analysis. Estimated cumulative incidence of death or neurological sequelae at maximum follow up was 19.8% (95% CI:10.2%, 31.3%). Heterogeneity (Iˆ2) was 88.57%, partly accounted for by year of data collection and reporting quality of studies. Incidence by acute disease severity was 0.00% (0.00, 0.00) for grade IIa; 17.0% (7.9, 28.2) for grade IIb/III; 81.6% (65.1, 94.5) for grade IV (p = 0.00) disease. HFMD with neurological involvement is associated with a substantial burden of long-term neurological sequelae. Grade of acute disease severity was a strong predictor of outcome. Strengths of this study include its bilingual approach and clinical applicability. Future prospective and interventional studies must use rigorous methodology to assess long-term outcomes in survivors. There was no specific funding for this study. See below for researcher funding.

New strategies for the treatment of acute venous thromboembolism.

PubMed

Prandoni, Paolo; Lensing, Anthonie W A; Pesavento, Raffaele

2006-11-01

In recent years, new opportunities have emerged that have the potential to change rapidly the therapeutic scenario of patients with acute venous thromboembolism (VTE). Selected patients with deep vein thrombosis (DVT) can be treated effectively and safely at home with fixed doses of low molecular weight heparins. The prompt administration of compression elastic stockings in addition to anticoagulant drugs in patients with acute DVT has the potential to halve the rate of late postthrombotic sequelae. The long-term use of low molecular weight heparins is likely to be more effective than oral anticoagulants for the secondary prevention of VTE in patients with advanced malignancy. Patients with pulmonary embolism and right ventricular dysfunction might benefit from the early administration of thrombolytic drugs in combination with heparin to a greater extent than from heparin alone. Despite an impressive amount of clinical information on the proper duration of oral anticoagulants in patients with unprovoked VTE, the optimal long-term treatment of these patients remains undefined. Finally, new categories of drugs are emerging that have the potential to replace conventional anticoagulants in the near future. They include compounds that inhibit factor Xa or thrombin.

Neurological Sequelae Resulting from Encephalitic Alphavirus Infection

Ronca, Shannon E.; Dineley, Kelly T.; Paessler, Slobodan

2016-01-01

The recent surge in viral clinical cases and associated neurological deficits have reminded us that viral infections can lead to detrimental, long-term effects, termed sequelae, in survivors. Alphaviruses are enveloped, single-stranded positive-sense RNA viruses in the Togaviridae family. Transmission of alphaviruses between and within species occurs mainly via the bite of an infected mosquito bite, giving alphaviruses a place among arboviruses, or arthropod-borne viruses. Alphaviruses are found throughout the world and typically cause arthralgic or encephalitic disease in infected humans. Originally detected in the 1930s, today the major encephalitic viruses include Venezuelan, Western, and Eastern equine encephalitis viruses (VEEV, WEEV, and EEEV, respectively). VEEV, WEEV, and EEEV are endemic to the Americas and are important human pathogens, leading to thousands of human infections each year. Despite awareness of these viruses for nearly 100 years, we possess little mechanistic understanding regarding the complications (sequelae) that emerge after resolution of acute infection. Neurological sequelae are those complications involving damage to the central nervous system that results in cognitive, sensory, or motor deficits that may also manifest as emotional instability and seizures in the most severe cases. This article serves to provide an overview of clinical cases documented in the past century as well as a summary of the reported neurological sequelae due to VEEV, WEEV, and EEEV infection. We conclude with a treatise on the utility of, and practical considerations for animal models applied to the problem of neurological sequelae of viral encephalopathies in order to decipher mechanisms and interventional strategies.

The Newborn Individualized Developmental Care and Assessment Program (NIDCAP) with Kangaroo Mother Care (KMC): Comprehensive Care for Preterm Infants

2014-01-01

State-of-the-art Newborn Intensive Care Units (NICUs), instrumental in the survival of high-risk and ever-earlier-born preterm infants, often have costly human repercussions. The developmental sequelae of newborn intensive care are largely misunderstood. Developed countries eager to export their technologies must also transfer the knowledge-base that encompasses all high-risk and preterm infants’ personhood as well as the neuro-essential importance of their parents. Without such understanding, the best medical care, while assuring survival jeopardizes infants’ long-term potential and deprives parents of their critical role. Exchanging the womb for the NICU environment at a time of rapid brain growth compromises preterm infants’ early development, which results in long-term physical and mental health problems and developmental disabilities. The Newborn Individualized Developmental Care and Assessment Program (NIDCAP) aims to prevent the iatrogenic sequelae of intensive care and to maintain the intimate connection between parent and infant, one expression of which is Kangaroo Mother Care. NIDCAP embeds the infant in the natural parent niche, avoids over-stimulation, stress, pain, and isolation while it supports self-regulation, competence, and goal orientation. Research demonstrates that NIDCAP improves brain development, functional competence, health, and life quality. It is cost effective, humane, and ethical, and promises to become the standard for all NICU care. PMID:25473384

Subarachnoid hemorrhage results in significant long-lasting neurologic sequelae. Here, we investigated whether human albumin improves long-term outcomes in experimental subarachnoid hemorrhage and whether neurovascular remodeling is involved in the protection of albumin. Laboratory investigation. Hospital research laboratory. Male Sprague-Dawley rats. Rats underwent subarachnoid hemorrhage by endovascular perforation. Albumin of either 0.63 or 1.25 g/kg was injected IV immediately after the surgery. Modified Garcia test, beam-walking test, novel object recognition, and Morris water maze were employed to determine the behavioral deficits. The effects of albumin on early neurovascular dysfunction and chronic synaptic plasticity were also studied. Both doses of albumin significantly improved the sensorimotor scores (F = 31.277; p = 0.001) and cognitive performance (F = 7.982; p = 0.001 in novel object recognition test; and F = 3.431; p = 0.026 in the latency analysis of Morris water maze test) for at least 40 days after subarachnoid hemorrhage. There were remarkable microvasculature hypoperfusion, intracranial pressure rise, early vasoconstriction, neural apoptosis, and degeneration in subarachnoid hemorrhage rats, with albumin significantly attenuating such neurovascular dysfunction. Furthermore, albumin markedly prevented blood-brain barrier disruption, as indicated by less blood-brain barrier leakage, preserved blood-brain barrier-related proteins, and dampened gelatinase activities. The expressions of key synaptic elements were up-regulated with albumin supplementation in both acute and chronic phases. Accordingly, a higher dendritic spine density was observed in the prefrontal and hippocampal areas of albumin-treated subarachnoid hemorrhage animals. Albumin at low-to-moderate doses markedly improves long-term neurobehavioral sequelae after subarachnoid hemorrhage, which may involve an integrated process of neurovascular remodeling.

Longitudinal behavior and achievement outcomes of traumatic brain injury (TBI) were investigated in 53 children with severe TBI, 56 children with moderate TBI, and 80 children with orthopedic injuries not involving brain insult. Measures of preinjury child and family status and of postinjury achievement skills were administered shortly after injury. Assessments were repeated 3 times across a mean follow-up interval of 4 years. Results from mixed model analysis revealed persisting sequelae of TBI. Recovery of math skills was observed in the severe TBI group but only for children from less stressed families. Social disadvantage in children with TBI predicted more adverse behavioral sequelae and less favorable changes in some outcome measures. The findings suggest that pediatric TBI has long-term effects on behavior and achievement but that postinjury progress is influenced by the family environment.

[Cleft lip, alveolar and palate sequelae. Proposal of new alveolar score by the Alveolar Cleft Score (ACS) classification].

PubMed

Molé, C; Simon, E

2015-06-01

The management of cleft lip, alveolar and palate sequelae remains problematic today. To optimize it, we tried to establish a new clinical index for diagnostic and prognostic purposes. Seven tissue indicators, that we consider to be important in the management of alveolar sequelae, are listed by assigning them individual scores. The final score, obtained by adding together the individual scores, can take a low, high or maximum value. We propose a new classification (ACS: Alveolar Cleft Score) that guides the therapeutic team to a prognosis approach, in terms of the recommended surgical and prosthetic reconstruction, the type of medical care required, and the preventive and supportive therapy to establish. Current studies are often only based on a standard radiological evaluation of the alveolar bone height at the cleft site. However, the gingival, the osseous and the cellular areas bordering the alveolar cleft sequelae induce many clinical parameters, which should be reflected in the morphological diagnosis, to better direct the surgical indications and the future prosthetic requirements, and to best maintain successful long term aesthetic and functional results.

Cerebral malaria is considered a leading cause of neuro-disability in sub-Saharan Africa among children and about 25% of survivors have long-term neurological and cognitive deficits or epilepsy. Their development was reported to be associated with protracted seizures, deep and prolonged coma. The study was aimed to determine the discharge pattern and to identify potential and informative predictors of neurological sequelae at discharge, complicating childhood cerebral malaria in central Sudan. A cross-sectional prospective study was carried out during malaria transmission seasons from 2000 to 2004 in Wad Medani, Sinnar and Singa hospitals, central Sudan. Children suspected of having cerebral malaria were examined and diagnosed by a Pediatrician for clinical, laboratory findings and any neurological complications. Univariate and multiple regression model analysis were performed to evaluate the association of clinical and laboratory findings with occurrence of neurological complications using the SPSS. Out of 940 examined children, only 409 were diagnosed with cerebral malaria with a mean age of 6.1 ± 3.3 yr. The mortality rate associated with the study was 14.2% (58) and 18.2% (64) of survivors (351) had neurological sequelae. Abnormal posture, either decerebration or decortication, focal convulsion and coma duration of >48 h were significant predictors for surviving from cerebral malaria with a neurological sequelae in children from central Sudan by Univariate analysis. Multiple logistic regression model fitting these variables, revealed 39.6% sensitivity for prediction of childhood cerebral malaria survivors with neurological sequelae (R² = 0.396; p=0.001). Neurological sequelae are common due to childhood cerebral malaria in central Sudan. Their prediction at admission, clinical presentation and laboratory findings may guide clinical intervention and proper management that may decrease morbidity and improve CM consequences.

More than half of neonatal stroke survivors have long-term sequelae, including seizures and neurological deficits. Although the immature brain has tremendous potential for recovery, mechanisms governing repair are essentially unexplored. We explored whether magnetic resonance imaging (MRI) early or late after transient middle cerebral arterial occlusion in 10-day-old (P10) rats can serve as an intermediate endpoint for long-term studies. Injured animals selected by diffusion-weighted MRI during middle cerebral arterial occlusion were scanned using T2-weighted MRI at P18 and P25 (injury volumes on MRI and histology were compared), or were subjected to contrast-enhanced MRI at P13 to characterize cerebral microcirculatory disturbances and blood-brain barrier leakage. Injury volume did not predict histological outcome at 2 weeks. Major reductions occurred by P18, with no further changes by P25. Cerebral perfusion was significantly reduced in the injured caudate but blood-brain barrier leakage was small. Therefore, conventional T2-weighted MRI performed during a subchronic injury phase predicts long-term histological outcome after experimental neonatal focal stroke. PMID:21670390

Severe Methanol Poisoning with Supralethal Serum Formate Concentration: A Case Report

Objective To present a case of survival without visual and central nervous system sequelae at a formate concentration of twice the reported lethal level. Clinical Presentation and Intervention This was a case of a 33-year-old man who ingested 1 liter of a toxic mixture of methanol and ethanol. Upon admission, he presented with anxiety, tachycardia and hypertension and had a serum formate level of 1,400 mg/l (normal range 0.9–2.1 mg/l), a methanol level of 806 mg/l (normal range 2–30 mg/l), an undetectable ethanol concentration and a normal lactate level. A 10% solution of ethanol and folinic acid was administered intravenously and two 8-hour sessions of intermittent hemodialysis were performed. The patient was discharged on the fifth day without sequelae of poisoning. The follow-up examinations 3 months and 2 years later revealed no damage to the basal ganglia. The patient had normal visual-evoked potential and findings on optical coherence tomography. The genetic analysis revealed a rare minor allele for the gene coding CYP2E1 enzyme of the microsomal ethanol oxidizing system. Conclusion The patient survived acute methanol poisoning without long-term sequelae despite a high serum level of formic acid upon admission. PMID:26380973

Delayed dyskinesia and prolonged psychosis in a patient presenting with profound hyponatraemia.

A 65-year-old woman was admitted to the emergency unit with a 48 h history of generalised weakness and confusion. On examination, she had mild slurring of speech although there was no other focal neurological deficit. She had profound hyponatraemia (serum sodium level of 100 mmol/L) on admission with the rest of her metabolic parameters being within normal range. Subsequent investigations confirmed the diagnosis of small-cell lung cancer with paraneoplastic syndrome of inappropriate antidiuresis (SIAD). She was monitored closely in high-dependency unit with an attempt to cautiously correct her hyponatraemia to prevent sequelae associated with rapid correction. The patient developed prolonged psychosis (lasting over 2 weeks) and displayed delayed dyskinetic movements, even after a gradual increase in serum sodium levels close to 130 mmol/L. To our knowledge, delayed neurological recovery from profound hyponatraemia (without long-term neurological sequelae) has previously not been reported. This case should alert a clinician regarding the possibility of prolonged although reversible psychosis and dyskinetic movements in a patient presenting with profound symptomatic hyponatraemia. Patients with profound hyponatraemia may develop altered sensorium, dyskinesia and psychotic behaviour.Full recovery from psychotic symptoms and dyskinesia may be delayed despite cautious correction of serum sodium levels.Careful and close monitoring of such patients can help avoid long-term neurological sequelae.

Hypoglycemia: When to Treat?

Hypoglycemia is the most common metabolic disorder encountered in neonates. The definition of hypoglycemia as well as its clinical significance and management remain controversial. Most cases of neonatal hypoglycemia are transient, respond readily to treatment, and are associated with an excellent prognosis. Persistent hypoglycemia is more likely to be associated with abnormal endocrine conditions, such as hyperinsulinemia, as well as possible neurologic sequelae. Manifestations of hypoglycemia include seizures which can result in noteworthy neuromorbidity in the long haul. Thus, hypoglycemia constitutes a neonatal emergency which requires earnest analytic assessment and prompt treatment. In this review, we have tried to cover the pathophysiology, the screening protocol for high-risk babies, management, long-term neurologic sequelae associated with neonatal hypoglycemia, with evidence-based answers wherever possible, and our own practices.

Healthcare-associated infections are a major problem in newborn infants, considering their high morbidity, mortality, and long-term sequelae. In preterm infants, it has been shown that skin and gastrointestinal tract colonization undergoes variations compared to healthy term infants, and that preterm infants are more exposed to nosocomial microorganisms given their higher probability of being admitted to the neonatal intensive care unit where they are cared for. This document reviews normal colonization, the changes observed during hospitalization, prematurity, and the potential role of chlorhexidine in the prevention of resistant microorganism transmission, as well as its side effects in newborn infants admitted to the neonatal intensive care unit.

Complaints of loss of memory and lack of concentration have been reported by long-term survivors of breast cancer. This mild cognitive impairment (MCI), also called "chemobrain" or "chemofog," has been the subject of a number of studies in the last few years. This cognitive impairment, although usually mild, must be studied to define possible risk factors for its development, and for future research into a preventive or therapeutic treatment approach. Long-term survivors of breast cancer must be followed to detect possible treatment sequelae as soon as possible. Since the number of these long-term survivors has increased in the last years, in part because of more active adjuvant treatments, our knowledge about the long-term side effects of these therapies has also grown.

Information on the consequences of perinatal asphyxia (PA) on brain morphology and function in the aging rat is missing although several groups have hypothesized that PA may be responsible for neurological and psychiatric deficits in the adult. We therefore decided to study the effects of PA on the central nervous system (CNS) in terms of morphology, immunohistochemistry, neurology and behavior in the aging animal. Hippocampus and cerebellum were evaluated morphologically by histological, immunohistochemical and magnetic resonance imaging and cerebellum also by stereological tests. Neurological function was tested by an observational test battery and rota rod test. Cognitive functions were examined by multiple-T-maze and the Morris water maze (MWM). Increased serotonin transporter (SERT) immunoreactivity in the CA2 region of the hippocampus and a significant difference in the escape latency, when the platform of the MWM was moved to a new location, were observed in asphyxiated rats. We showed that deteriorated cognitive functions accompanied by aberrant expression of hippocampal SERT and impaired relearning are long-term sequelae of perinatal asphyxia, a finding that may form the basis for understanding CNS pathology in the aging subject, animal or human.

Antipsychotic drugs are increasingly used in children and adolescents to treat a variety of psychiatric disorders. However, little is known about the long-term effects of early life antipsychotic drug (APD) treatment. Most APDs are potent antagonists or partial agonists of dopamine (DA) D2 receptors ; atypical APDs also have multiple serotonergic activities. DA and serotonin regulate many neurodevelopmental processes. Thus, early life APD treatment can, potentially, perturb these processes, causing long-term behavioural and neurobiological sequelae. We treated adolescent, male rats with olanzapine (Ola) on post-natal days 28–49, under dosing conditions that approximate those employed therapeutically in humans. As adults, they exhibited enhanced conditioned place preference for amphetamine, as compared to vehicle-treated rats. In the nucleus accumbens core, DA D1 receptor binding was reduced, D2 binding was increased and DA release evoked by electrical stimulation of the ventral tegmental area was reduced. Thus, adolescent Ola treatment enduringly alters a key behavioural response to rewarding stimuli and modifies DAergic neurotransmission in the nucleus accumbens. The persistence of these changes suggests that even limited periods of early life Ola treatment may induce enduring changes in other reward-related behaviours and in behavioural and neurobiological responses to therapeutic and illicit psychotropic drugs. These results underscore the importance of improved understanding of the enduring sequelae of paediatric APD treatment as a basis for weighing the benefits and risks of adolescent APD therapy, especially prophylactic treatment in high-risk, asymptomatic patients.

Tackling in Youth Football.

2015-11-01

American football remains one of the most popular sports for young athletes. The injuries sustained during football, especially those to the head and neck, have been a topic of intense interest recently in both the public media and medical literature. The recognition of these injuries and the potential for long-term sequelae have led some physicians to call for a reduction in the number of contact practices, a postponement of tackling until a certain age, and even a ban on high school football. This statement reviews the literature regarding injuries in football, particularly those of the head and neck, the relationship between tackling and football-related injuries, and the potential effects of limiting or delaying tackling on injury risk.

Treatment of Acute Pelvic Inflammatory Disease

PubMed Central

Sweet, Richard L.

2011-01-01

Pelvic inflammatory disease (PID), one of the most common infections in nonpregnant women of reproductive age, remains an important public health problem. It is associated with major long-term sequelae, including tubal factor infertility, ectopic pregnancy, and chronic pelvic pain. In addition, treatment of acute PID and its complications incurs substantial health care costs. Prevention of these long-term sequelae is dependent upon development of treatment strategies based on knowledge of the microbiologic etiology of acute PID. It is well accepted that acute PID is a polymicrobic infection. The sexually transmitted organisms, Neisseria gonorrhoeae and Chlamydia trachomatis, are present in many cases, and microorganisms comprising the endogenous vaginal and cervical flora are frequently associated with PID. This includes anaerobic and facultative bacteria, similar to those associated with bacterial vaginosis. Genital tract mycoplasmas, most importantly Mycoplasma genitalium, have recently also been implicated as a cause of acute PID. As a consequence, treatment regimens for acute PID should provide broad spectrum coverage that is effective against these microorganisms. PMID:22228985

A long-term observation has been made in 58 patients (30 males and 28 females) with severe sequelae of neonatal anoxic encephalopathy. They aged from 8 months to 65 years. All of them had motor disturbances and profound mental retardation. Motor function was improved in 4 patients with aging. In contrast, motor activity deteriorated in 11 cases, of which 4 showed a mental regression. Among them, patients who had originally better motor ability than sitting were likely to deteriorate by uncontrollable epilepsy and/or excessive administration of anticonvulsants. Regression of the patients with worse motor ability like bedridden appeared to attributable hypertonia of muscles and bodily deformation. Fifteen cases showed an exacerbation of general condition which originated predominantly to respiratory distress. Twelve patients died including 6 exacerbated cases. Exacerbation or death may have occurred frequently in specific periods of infancy, adolescence and youth with the patients who showed very low motor function such as bedridden and no locomotion.

The Impact of Traumatic Brain Injury on the Aging Brain.

Young, Jacob S; Hobbs, Jonathan G; Bailes, Julian E

2016-09-01

Traumatic brain injury (TBI) has come to the forefront of both the scientific and popular culture. Specifically, sports-related concussions or mild TBI (mTBI) has become the center of scientific scrutiny with a large amount of research focusing on the long-term sequela of this type of injury. As the populace continues to age, the impact of TBI on the aging brain will become clearer. Currently, reports have come to light that link TBI to neurodegenerative disorders such as Alzheimer's and Parkinson's diseases, as well as certain psychiatric diseases. Whether these associations are causations, however, is yet to be determined. Other long-term sequelae, such as chronic traumatic encephalopathy (CTE), appear to be associated with repetitive injuries. Going forward, as we gain better understanding of the pathophysiological process involved in TBI and subclinical head traumas, and individual traits that influence susceptibility to neurocognitive diseases, a clearer, more comprehensive understanding of the connection between brain injury and resultant disease processes in the aging brain will become evident.

In up to 10% of patients who experience abdominal trauma, renal and urogenital systems will be involved. In polytrauma patients with other potentially life-threatening injuries, renal and genitourinary trauma may be overlooked initially, but a delayed or missed diagnosis of these injuries may result in preventable complications. This review provides a best-practice approach to the diagnosis and management of renal and genitourinary injuries, with an emphasis on the systematic approach needed to identify subtle injuries and avoid long-term urinary sequelae such as hypertension, incontinence, erectile dysfunction, chronic kidney disease, and nephrectomy.

Role for Primary Repair of Deltoid Ligament Complex in Ankle Fractures.

PubMed

Rigby, Ryan B; Scott, Ryan T

2018-04-01

Acute deltoid injuries may occur with ankle fractures. They are often left to heal without repair, possibly leading to chronic medial ankle instability. Stress radiographs identify the need for surgical repair of fractures or soft tissue damage. Gravity stress views have benefits over manually stressing the ankle. MRI can explore the extent of medial soft tissue injuries. Arthroscopy can evaluate and potentially treat deltoid injuries. Interposition of the deltoid may preclude adequate fracture reduction. Except with deltoid tear, fractures should be reduced and fixated, then the deltoid assessed. With persistent instability, primary repair may prevent long-term sequelae.

A 19-year-old male patient was diagnosed with S. sanguinis brain abscess of unknown etiopathology as a complication of subclinical endocarditis. While viridans streptococci are implicated in dental seeding to the heart, S. sanguinis brain abscesses are rare. Six previous cases of S. sanguinis brain abscess in the literature reported dental procedures and maxillofacial trauma. In our patient, there was no obvious source of infective endocarditis preceding the development of brain abscess. This demonstrates the importance of prompt diagnosis and initiation of antimicrobial therapy given the potential for long-term sequelae such as focal deficits and seizures.

A new arena in cardiac surgery: Pediatric coronary artery bypass surgery

PubMed Central

KITAMURA, Soichiro

2018-01-01

Prior to the 1970s, pediatric coronary artery bypass surgery (PCABS) was seldomly performed due to the lack of compelling surgical indications. The advent of coronary sequelae secondary to Kawasaki disease (KD) and the occurrence of coronary artery complications due to newly developed procedures, such as the arterial switch operation and early repair for intrinsic congenital coronary malformations, necessitated the development of PCABS. Because children grow rapidly and their life expectancy is very long, with increasing exercise capability requirements, the strategy for PCABS should differ from that for bypass surgery in adults. PCABS utilizing unilateral and bilateral internal thoracic arteries (ITA) has become the most reliable surgical method for children because of the distinct structure of ITAs being resistant to KD, growth potential according to the child’s somatic growth and long-term patency without wall degeneration. This operation utilizing ITA grafts is now being performed worldwide and is referred to as the “Kitamura operation” for KD coronary sequelae. Notably, the use of vein grafts should be avoided in children. Likewise, this operation can now be successfully performed in infants using a surgical microscope, for congenital coronary disorders. Currently, PCABS with ITAs has been established as a new arena in cardiac surgery, following our initial attempts. PMID:29321443

This study describes the long-term complications in children with Haemophilus influenzae serotype b (Hib) vaccine failure and to determine their risk of other serious infections. The families of 323 children with invasive Hib disease after appropriate vaccination (i.e. vaccine failure) were contacted to complete a questionnaire relating to their health and 260 (80.5%) completed the questionnaire. Of the 124 children with meningitis, 18.5% reported serious long-term sequelae and a further 12.1% of parents attributed other problems to Hib meningitis. Overall, 14% (32/231 cases) of otherwise healthy children and 59% (17/29 cases) of children with an underlying condition developed at least one other serious infection requiring hospital admission. In a Poisson regression model, the risk of another serious infection was independently associated with the presence of an underlying medical condition (incidence risk ratio (IRR) 7.6, 95% CI 4.8-12.1; p<0.0001), both parents having had a serious infection (IRR 4.1, 95% CI 1.6-10.3; p=0.003), requirement of more than two antibiotic courses per year (IRR 2.3, 95% CI 1.4-3.6; p=0.001) and the presence of a long-term complication after Hib infection (IRR 1.8, 95% CI 1.1-3.1; p=0.03). Thus, rates of long-term sequelae in children with vaccine failure who developed Hib meningitis are similar to those in unvaccinated children in the pre-vaccine era. One in seven otherwise healthy children (14%) with Hib vaccine failure will go on to suffer another serious infection requiring hospital admission in childhood, which is higher than would be expected for the UK paediatric population.

Although it has been reported that awake neurosurgical procedures are well tolerated, the long-term occurrence of general psychological sequelae has not yet been investigated. This study assessed the frequency and effects of psychological symptoms after an awake craniotomy on health-related quality of life (HRQOL). Sixteen patients undergoing an awake surgery were surveyed with a self-developed questionnaire, the Posttraumatic Stress Disorder Inventory For Awake Surgery Patients, which adopts the core components of the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) posttraumatic stress disorder (PTSD) criteria. The mean time between surgery and data collection was 97.3 ± 93.2 weeks. Health-related quality of life was assessed with the 36-Item Short Form Health Survey. Forty-four percent of the patients stated that they had experienced either repetitive distressing recollections or dreams related to the awake surgery, 18.8% stated persistent avoidance of stimuli associated with the awake surgery, and symptoms of increased arousal occurred in 62.5%. Two patients presented with postoperative psychological sequelae resembling PTSD symptoms. Younger age at surgery and female sex were risk factors for symptoms of increased arousal. The experience of intense anxiety during awake surgery appears to favor the development of postsurgical PTSD symptoms, while recurrent distressing recollections particularly affect HRQOL negatively. In many cases awake craniotomy is necessary to preserve language and motor function. However, in some cases awake craniotomy can lead to postoperative psychological sequelae resembling PTSD symptoms. Therefore, possible long-term effects of an awake surgery should be considered and discussed with the patient when planning this type of surgery.

Diagnosis, treatment, clinical course, and prognosis of childhood-onset craniopharyngioma patients.

PubMed

Müller, Hermann L

2017-12-01

For decades gross-total resection was the preferred treatment option in childhood-onset craniopharyngioma, assuming that radical strategies at the time of initial diagnosis and treatment would result in cure. Recent reports on long-term prognosis, novel treatment approaches, and molecular genetics provide new insights into more risk-adapted treatment strategies in order to prevent sequelae such as hypothalamic syndrome. A search for original articles published between 2000 and 2016 was performed in PubMed, Science Citation Index Expanded, EMBASE and Scopus. The search terms used were "craniopharyngioma", "hypothalamus", "pituitary", "obesity", "irradiation", and "neurosurgery". The clinical, neuroradiological and surgical definition of hypothalamic involvement is a fundamental factor related to postoperative poor outcome, progressive obesity and neuropsychological impairment after surgical removal. There is a need to change the previous "gold-standard" objective of a primary radical tumor removal in all cases by the new paradigm of a limited resection plus focused radiotherapy in patients with hypothalamic lesions. Hypothalamic involvement and treatment-related hypothalamic lesions are associated with the highest risk of postoperative sequelae. Three dimensional intensity modulated proton beam radiotherapy has potential advantage of over photon beam methods to focus and limit the radiation effects to optic and hypothalamic structures. Preclinical, in vivo mouse models of craniopharyngioma have potential advantage to investigate molecular pathways deregulated in the tumor and to test the use of specific drugs. As expertise has been shown to have impact on post-treatment morbidity, medical societies should establish criteria of adequate professional expertise for the treatment of craniopharyngioma.

Extended Whipple procedures may require division of the splenic vein (SV). Controversy exists regarding the risk of sequelae of sinistral portal hypertension when the SV is ligated without reimplantation. The aim of this study was to identify postoperative venous collateral patterns and sequelae of SV ligation, as well as long-term results in an extended Whipple procedure. Patients who had an extended Whipple procedure (Whipple at the Splenic Artery or WATSA) were entered in an institutional database. Evaluation of the venous collaterals was performed at least 5 months postoperatively by imaging. Spleen size and platelet counts were measured before and after operation. Fifteen patients were entered from 2009 to 2014. SV was not reconstructed and the IMV-SV junction was always resected. Two collateral routes developed. An inferior route was present 14/15 patients. It connected the residual SV to the SMV via intermediate collateral veins in the omentum and along the colon. A superior route, present in 10/15 patients connected the residual SV to the portal vein via gastric, perigastric, and coronary veins. Gastrointestinal bleeding did not occur. Mean platelet count and spleen size were not affected significantly. Procedures were long, but few severe complications developed. In 12 patients with adenocarcinoma, the median survival has not been reached. Patients who have SV ligation in an extended Whipple are protected against sequelae of sinestral portal hypertension by inferior collateral routes. The omentum and marginal veins of the colon are key links in this pathway.

We investigated the efficacy of Qi therapy as a non-pharmacological treatment for various symptoms presented by Korean combat veterans of the Vietnam War with Agent Orange Sequelae. Nine subjects volunteered to receive 30 minutes of Qi therapy, twice per day for 7 days. There was marked improvement in 89% of the patients with impaired physical activity, 86% of those with psychological disorder, 78% of those with heavy drug use, and 67% of those with fatigue, indigestion and high blood glucose levels. This data suggests that Qi therapy combined with conventional treatment has positive effects in reducing and managing the pain, psychosomatic disorders, and substance abuse in patients with Agent Orange Sequelae. We cannot completely discount the possible influence of the placebo effect, and more objective, clinical measures are needed to study the long-term effects of Qi therapy.

Neurologic sequelae of cardiac surgery in children.

PubMed

Ferry, P C

1987-03-01

Major advances in surgical and cardiopulmonary bypass technology have occurred in the past 30 years. Total correction of previously inoperable congenital cardiac defects is being performed with increasing frequency and in children at progressively younger ages. While the majority of children undergoing cardiac surgery survive without incident, increasing concern is being raised about neurologic sequelae seen in some survivors. Complications such as embolization, hypoxia, inadequate cerebral perfusion, and biochemical disturbances may all lead to brain damage following cardiac surgery. Acute postoperative neurologic problems include seizures, impaired levels of consciousness, focal motor deficits, and movement disorders. Long-term sequelae include language and learning disorders, mental retardation, seizures, and cerebral palsy. Intraoperative cerebral monitoring techniques are as yet imperfect, but their use in combination with meticulous intraoperative and postoperative care currently provides the best means of reducing neurologic morbidity. Future studies should explore other methods of preserving neurologic integrity in children undergoing open heart surgery.

Intrauterine growth restriction (IUGR) and fetal growth restriction (FGR) are pregnancy complications associated with morbidity in later life. Despite a growing body of evidence from current research on developmental origins of health and disease (DOHaD), little information is currently provided to parents on long-term metabolic, cardiovascular and neurologic consequences. As parents strongly rely on internet-based health-related information, we examined the quality of information on IUGR/FGR sequelae and DOHaD in webpages used by laypersons. Simulating non-clinicians experience, we entered the terms 'IUGR consequences' and 'FGR consequences' into Google and Yahoo search engines. The quality of the top search-hits was analyzed with regard to the certification through the Health On the Net Foundation (HON), currentness of cited references, while reliability of information and DOHaD-related consequences were assessed via the DISCERN Plus score (DPS). Overall the citation status was not up-to-date and only a few websites were HON-certified. The results of our analysis showed a dichotomy between the growing body of evidence regarding IUGR/FGR-related sequelae and lack of current guidelines, leaving parents without clear directions. Furthermore, detailed information on the concept of DOHaD is not provided. These findings emphasize the responsibility of the individual physician for providing advice on IUGR/FGR-related sequelae, monitoring and follow-up.

To describe how the quality of life (QOL) discussion in childhood medulloblastoma (MB) relates to treatment developments, survival and sequelae from 1920 to 2014. Articles containing "childhood medulloblastoma" and "quality of life" were identified in PubMed. Those containing phrases pertaining to psychological, emotional, behavioral or social adjustment in the title, abstract or keywords were selected. Inclusion of relevant older publications was assured by cross-checking references. 1920-1930s: suction, electro-surgery, kilovolt (KV) irradiation. Survival = months. Focus on operative mortality, symptoms and survival. 1940s: radiotherapy improved. 1950s: chemotherapy and intubation. Survival = years. Opinions oscillated between optimism/awareness of physical sequelae of radiotherapy. 1960s: magnified vision, ventriculo-peritoneal (VP) shunts, megavolt (MV) irradiation. Long-term survival shifted the attention towards neurological problems, disability and carcinogenesis of radiotherapy. 1970s: CT, microscope, bipolar coagulation, shunt filters, neuroanesthesia, chemotherapy trials and staging studies. Operative mortality decreased and many patients (re)entered school; emphasis on neuropsychological sequelae, IQ and academic performance. 1980s: magnetic resonance imaging (MRI), Cavitron ultrasonic aspiration (CUSA), laser surgery, hyper-fractionated radiotherapy (HFRT). Cerebellar mutism, psychological and social issues. 1990s: pediatric neurosurgery, proton beams, stem cell rescue. Reflections on QOL as such. 21st century: molecular genetics. Premature aging, patterns of decline, risk- and resilience factors. QOL is a critical outcome measure. Focus depends on survival and sequelae, determined after years of follow-up. Detailed measurements are limited by time, money and human resources, and self-reporting questionnaires represent a crude measure limited by subjectivity. Therapeutic improvements raise the question of QOL versus cure. QOL is a potential primary research endpoint; multicenter international studies are needed, as are web-based tools that work across cultures.

NICE guidelines state that patients with psychological contra-indications should not be considered for bariatric surgery, including Laparoscopic Adjustable Gastric Banding (LAGB) surgery as treatment of morbid obesity, although no consistent correlation between psychiatric illness and long-term outcome in LAGB has been established. This is to our knowledge the first study to evaluate long-term outcomes in LAGB for a full range of DSM-IV defined psychiatric and eating disorders, and forms part of a research portfolio developed by the authors aimed at defining psychological predictors of bariatric surgery in the short-, medium- and long-term. Case notes of 37 subjects operated on between April 1997 and June 2000, who had undergone structured clinical interview during pre-surgical assessment to yield diagnoses of mental and eating disorders according to DSM-IV criteria were analyzed according to a set of operationally defined criteria. Statistical analysis was carried out to compare those with a poor outcome and those considered to have a good outcome in terms of psychiatric profile. In this group of mainly female, Caucasian subjects, ranging in age from 27 to 60 years, one-third were diagnosed with a mental disorder according to DSM-IV criteria. The development of postoperative DSM-IV defined binge eating disorder (BED) or depression strongly predicted poor surgical outcome, but pre-surgical psychiatric factors alone did not. Although pre-surgical psychiatric assessment alone cannot predict outcome, an absence of preoperative psychiatric illness should not reassure surgeons who should be mindful of postoperative psychiatric sequelae, particularly BED. The importance of providing an integrated biopsychosocial model of care in bariatric teams is highlighted.

The Fontan operation is the final step of palliation for patients with a functionally single ventricle. Since its introduction in the 1970s, the Fontan surgery has become part of a successful surgical strategy that has improved single ventricle mortality. In recent years, we have become more aware of the limitations and long-term consequences of the Fontan physiology. Pulmonary vascular resistance plays an important role in total cavopulmonary circulation, and has been identified as a potential therapeutic target to mitigate Fontan sequelae. In this review, we will discuss the results of different pulmonary vasodilator trials and the use of pulmonary vasodilators as a treatment strategy for Fontan patients.

Early detection and treatment of breast cancer, leading to longer survival, has revealed the natural history of this disease process. Linitis plastica of the stomach is a potential long-term sequela of metastatic breast cancer. Here we present a case of metastatic breast cancer presenting as linitis plastica, as well as the treatment algorithm for this rare clinical entity. The world literature describes a clear pattern of linitis plastica for metastatic infiltrating lobular breast cancer and a discrete nodular pattern for infiltrating ductal cancer, in regard to metastasis to the stomach. To our knowledge, this is the first case of infiltrating ductal cancer presenting as linitis plastica of the stomach.

[Update on congenital and neonatal herpes infections: infection due to cytomegalovirus and herpes simplex].

PubMed

Baquero-Artigao, F

2017-05-17

Newborn infants are a population which is especially susceptible to viral infections that frequently affect the central nervous system. Herpes infections can be transmitted to the foetus and to the newborn infant, and give rise to severe clinical conditions with long-term sensory and cognitive deficits. Two thirds of newborn infants with encephalitis due to herpes simplex virus and half of the children with symptomatic congenital infection by cytomegalovirus develop sequelae, which results in high community health costs in the long term. Fortunately, the better knowledge about these infections gained in recent years together with the development of effective antiviral treatments have improved the patients' prognosis. Valganciclovir (32 mg/kg/day in two doses for six months) prevents the development of hypoacusis and improves the neurological prognosis in symptomatic congenital infection due to cytomegalovirus. Acyclovir (60 mg/kg/day in three doses for 2-3 weeks) prevents the development of severe forms in skin-eyes-mouth herpes disease, and lowers the rate of mortality and sequelae when the disease has disseminated and is located in the central nervous system.

Lung disease in indigenous children.

PubMed

Chang, A B; Brown, N; Toombs, M; Marsh, R L; Redding, G J

2014-12-01

Children in indigenous populations have substantially higher respiratory morbidity than non-indigenous children. Indigenous children have more frequent respiratory infections that are, more severe and, associated with long-term sequelae. Post-infectious sequelae such as chronic suppurative lung disease and bronchiectasis are especially prevalent among indigenous groups and have lifelong impact on lung function. Also, although estimates of asthma prevalence among indigenous children are similar to non-indigenous groups the morbidity of asthma is higher in indigenous children. To reduce the morbidity of respiratory illness, best-practice medicine is essential in addition to improving socio-economic factors, (eg household crowding), tobacco smoke exposure, and access to health care and illness prevention programs that likely contribute to these issues. Although each indigenous group may have unique health beliefs and interfaces with modern health care, a culturally sensitive and community-based comprehensive care system of preventive and long term care can improve outcomes for all these conditions. This article focuses on common respiratory conditions encountered by indigenous children living in affluent countries where data is available. Crown Copyright © 2014. Published by Elsevier Ltd.

Detection of gadolinium deposits in patients who have repeatedly been administered intravenous gadolinium chelates have given rise to concern regarding the long-term safety of magnetic resonance imaging (MRI) contrast media. Nevertheless, negative long-term clinical effects have not yet been observed. In some publications parallels have been drawn to the sequelae of thorotrast that was formerly used for arterial angiography. In this article the history of thorotrast use is briefly described and in particular why, despite warnings, this substance was used frequently and worldwide. A brief summary of the results of the German Thorotrast Study revealed that high excess rates were only observed for primary malignant liver tumors after a 15-year or longer latency period and to a lesser degree of leukemias, as well as for severe local complications due to paravascular injections, particularly in the neck region. Based on this historical review, we will venture to take stock of the outcome from the "success story" of this contrast agent.

[Psychosocial issues of long-term cancer survivors].

PubMed

Weis, J; Faller, H

2012-04-01

Although cancer incidence rates are increasing, recent statistical studies suggest that cancer patients are showing higher cure rates as well as improved overall survival rates for most cancer locations. These advances are explained by improved strategies in early diagnoses as well as improved cancer therapies. Therefore, the number of long-term cancer survivors has also increased, but only few studies, especially within the last years, have focused on psychosocial issues of this subgroup. Some studies show that overall quality of life of long-term cancer survivors is quite high and comparable to that of the normal population. Nevertheless, a substantial percentage of former patients shows reduced quality of life and suffers from various sequelae of cancer and its treatment. This review focuses on the most common psychosocial issue of long-term survivors such as reduced psychological wellbeing, neuropsychological deficits and cancer-related fatigue syndrome. Finally, recommendations for problem-oriented interventions as well as improvement of psychosocial care of long-term survivors are given.

Global temperatures are rising; extreme environmental heat can result in adverse health effects including heatstroke. Acute effects of heat are well recognised, but there is less understanding of potential long-term adverse outcomes. Our aim was to review recent medical literature for clinical cases of environmental heatstroke with a focus on neurological outcome. Structured search strategies were designed to retrieve publications of heatstroke case reports using Ovid Medline and Embase (2000-2016). One thousand and forty-nine abstracts were identified, and after application of exclusion criteria 71 articles deemed relevant. Ninety cases were identified from 71 articles. 100% presented with acute neurological symptoms; 87.8% presented with non-neurological symptoms. 44.4% patients recovered fully, 23.3% died, 23.3% suffered convalescent or long-term neurological sequelae, and in 8.9% no long-term follow up was available. 57.1% of the patients who died or had a neurological deficit had no documented co-morbidity. Patterns of neurological deficits included 66.7% patients with motor dysfunction, 9.5% cognitive impairment, 19% both motor and cognitive impairment and 4.7% other. In total 71.4% of the impaired patients had long-term cerebellar dysfunction. Adverse long-term neurological outcomes were common in surviving patients presenting with environmental heatstroke. Permanent neurological deficits were present in 34.4% of survivors where outcome was known; many were young, healthy individuals. Cerebellar injury was common suggesting cerebellar structures are vulnerable to heat. These findings highlight that people of all ages and pre-morbid states are at risk of severe heat-related illness. In the face of climate change, effective interventions for heat-related illness, including both treatment and prevention are necessary. © 2018 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Conservative treatment of postoperative chylothorax: a case report.

PubMed

Wagh, Sachinkumar; Deshmukh, Sanjay; Ankolikar, Shrikant

2018-02-06

Chylothorax is a well-documented complication of thoracic trauma and is associated with high rates of morbidity and mortality. Treatment for chylothorax includes conservative measures (total parenteral nutrition, pleural drainage, and pleurodesis) and surgery (thoracic duct ligation). We present the case of a 65-year-old man who developed chylothorax after an elective surgical procedure. In this report conservative treatment aims to reduce chyle flow, to drain the pleural cavity in an effective manner, and to prevent chronic sequelae. Optimal conservative treatment, started immediately upon diagnosis, effectively reduces the need for reoperation and long-term hospitalization, and it might prevent further sequelae of chylothorax. The chylothorax was successfully treated conservatively, which may reduce the need for reoperation.

This report presents the 5-year follow-up of 137 children with respiratory tuberculosis enrolled in a randomised clinical trial of two different anti-tuberculosis regimens 9HR and 2HRZ3/4RH2. Both regimens had similar cure rates, with low relapse rates and mortality. Of 134 children followed up to 5 years, 86% had normal radiographs, with more sequelae in the 9HR group (15% vs. 1.5%, P < 0.01). One patient relapsed and there was one accidental death. Short-course chemotherapy in children is safe, effective and well tolerated, and leads to excellent long-term results, with a small proportion of children left with radiological sequelae.

What Ever Happened To The ‘Cool’ Kids? Long-Term Sequelae Of Early Adolescent Pseudomature Behavior

2014-01-01

Pseudomature behavior—ranging from minor delinquency to precocious romantic involvement—is widely viewed as a nearly normative feature of adolescence. When such behavior occurs early in adolescence, however, it was hypothesized to reflect a misguided overemphasis upon impressing peers and was considered likely to predict long-term adjustment problems. In a multi-method, multi-reporter study following a community sample of 184 adolescents from age 13 to 23, early adolescent pseudomature behavior was linked cross-sectionally to a heightened desire for peer popularity and to short-term success with peers. Longitudinal results, however, supported the study’s central hypothesis: Early adolescent pseudomature behavior predicted long-term difficulties in close relationships, as well as significant problems with alcohol and substance use, and elevated levels of criminal behavior.

To discuss the history of cancer survivorship, related quality-of-life issues, and cancer survivorship care plans (CSCPs). CINAHL, PubMed, published articles, and Web sites. A cancer survivor is an individual who has been diagnosed with cancer, regardless of when that diagnosis was received, who is still living. Cancer survivorship is complex and involves many aspects of care. Major areas of concern for survivors are recurrence, secondary malignancies, and long-term treatment sequelae that affect quality of life. Four essential components of survivorship care are prevention, surveillance, intervention, and coordination. A CSCP should address the survivor's long-term care, such as type of cancer, treatments received, potential side effects, and recommendations for follow-up. It should include preventive practices, how to maintain health and well-being, information on legal protections regarding employment and health insurance, and psychosocial services in the community. Survivorship care for patients with cancer requires a multidisciplinary effort and team approach. Enhanced knowledge of long-term complications of survivorship is needed for healthcare providers. Further research on evidence-based practice for cancer survivorship care also is necessary. Nurses can review CSCPs with patients, instruct them when to seek treatment, promote recommended surveillance protocols, and encourage behaviors that lead to cancer prevention and promote well-being for cancer survivors.

1986-01-01

The long term respiratory consequences of whooping cough in childhood were sought among members of the National Survey of Health and Development. Peak expiratory flow rate was measured when the survey members were 36 years old and seven respiratory symptoms were reported at the same time. Peak expiratory flow rate was slightly reduced in those who had had whooping cough as a child, and this difference became non-significant when other factors were taken into account. Unexpectedly, chronic cough was significantly less likely to be reported by those who had had whooping cough, and this difference remained significant only among men after other factors had been taken into account. This study failed to show a long term detrimental effect of whooping cough on the respiratory system. PMID:3081115

Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Because of major improvements in treatment protocols, the survival rate now exceeds 80%. However, ALL treatments can cause long-term neurocognitive sequelae, which negatively impact academic achievement and quality of life. Therefore, cognitive sequelae need to be carefully evaluated. The DIVERGT is a battery of tests proposed as a screening tool, sensitive to executive function impairments in children and adolescent cancer survivors. Our study aimed at verifying the predictive value of the DIVERGT on general cognitive functioning in adult long-term survivors of ALL. ALL survivors completed the DIVERGT 13.4 years, on average, after remission (N = 247). In addition, 49 of these survivors (equally selected amongst those with low, average, and high DIVERGT scores) as well as 29 controls completed a more comprehensive neuropsychological evaluation within a 3-year period from DIVERGT administration. Multivariate regression analysis was used to assess the predictive value of the DIVERGT on general intelligence, mathematics, verbal memory, and working memory. As a follow-up analysis, three performance groups were created based on the DIVERGT results. Multivariate analysis of variance (MANOVA) assessed neuropsychological differences between groups. The DIVERGT accurately predicted General Ability Index (GAI) (P < 0.0001), mathematics (P < 0.0001) and verbal memory (P = 0.045). Moreover, the low-performance group consistently had poorer performance than the high-performance and control groups on the neuropsychological tests. The DIVERGT is a useful, time-effective screening battery for broader neurocognitive impairments identification in long-term adult ALL survivors. It could be implemented as routine examination in cancer follow-up clinics. © 2018 Wiley Periodicals, Inc.

An overview of concussion in sport.

PubMed

Khurana, Vini G; Kaye, Andrew H

2012-01-01

Concussion is a sudden-onset, transient alteration of consciousness due to a combination of functional and structural brain disturbances following a physical impact transmitted to the brain. It is a common, although likely underreported, condition encountered in a wide range of sports. In the Australian Football League, concussion is estimated to occur at a rate of approximately seven injuries per team per season. While many instances of concussion are clinically mild, there is emerging evidence that a player's full recovery from a concussive injury may be more delayed and the sequelae of repeated concussions more severe than previously thought. In this light, a more conservative and rigorous approach to managing players with concussive injuries may be warranted, with the guiding principle being the player's immediate and long-term welfare. The current paper reviews the sports concussion literature. The definition, epidemiology, aetiology, pathophysiology, structural pathology, clinical features, assessment and investigation, treatment principles, and short-term and potential long-term complications of concussion are discussed. Special considerations in paediatric sports concussion, and the return-to-play implications of immediate, evolving and repetitive brain injury are also considered, as are the emerging concept and possible implications of subconcussive injury.

Concussion legislation has been enacted in all 50 of the United States, aiming to prevent mild traumatic brain injuries and the potential long-term sequelae of these injuries in youth athletics. Sports medicine providers, in addressing this major public health concern, are tasked with adhering to the established standards of medical care while also considering the legal implications. The PubMed (2011-2016) database was searched using the following search terms: concussion, sports concussion, legislation, and concussion legislation. References from consensus statements, review articles, and book chapters were also utilized. Clinical review. Level 4. The Lystedt law and its progeny have increased awareness of the signs and symptoms of sports concussion, but adherence to state legislation can pose some challenges. The presence of concussion legislation places a responsibility on the sports medicine provider to have a firm understanding of the legality of concussion management in the state(s) in which they practice. © 2016 The Author(s).

Insulin resistance, the metabolic syndrome, diabetes, and cardiovascular disease risk in women with PCOS.

Polycystic ovary syndrome is the most common endocrinopathy of reproductive aged women affecting 6-10% of the population. Traditionally considered a reproductive disorder manifesting as chronic anovulation, infertility, and hyperandrogenism, management has primarily focused on short-term reproductive outcomes. Recently, however, significant metabolic aspects in conjunction with longer-term health sequealae of PCOS have been recognized. The metabolic features are primarily related to underlying insulin resistance (IR), which is now understood to play an important role in both the pathogenesis and long-term sequelae of PCOS.

Cerebral metabolism and functioning depends upon an adequate blood glucose supply which provides for majority of the brain's energy requirement. Studies from the past have shown that neonatal hypoglycemia is associated with acute and long term neurological sequelae. Early discharge without adequately established breast feeding may lead to feeding problems, post discharge hypoglycemia and its associated neurological complications. The authors describe one such case of an exclusively breast fed term newborn who presented on day 3 with symptomatic hypoglycemia and associated neurological injury.

History of neuropsychological study of sport-related concussion.

Webbe, Frank M; Zimmer, Adam

2015-01-01

Although the medical literature has a long history of description and comment on concussion, the occurrence of concussion within the context of sports other than boxing was not judged to be problematic until the 1980s. Neuropsychological assessment played a critical and integral role in identifying the cognitive sequelae of concussion and mapping out the short- and long-term vagaries in recovery. This paper captures that history and expands upon current applications of neuropsychological assessment in the diagnosis and management of sport-related concussion.

Prolonged grieving after abortion: a descriptive study.

PubMed

Brown, D; Elkins, T E; Larson, D B

1993-01-01

Although flawed by methodological problems, the research literature tends to provide support for the assumption that induced abortion in the 1st trimester is not accompanied by enduring negative psychological sequelae. In cases where such sequelae are reported, the morbidity is attributed to a pre-existing psychiatric condition or circumstances precipitating the choice of abortion. However, detailed descriptive letters from 45 women prepared in response to a request by a pastor of an upper-middle-class Protestant congregation in Florida indicate that prolonged grieving after abortion may be more widespread phenomenon than previously believed. Letter writers ranged in age from 25-60 years; 75% were unmarried at the time of the procedure and 29% aborted before the legalization of abortion in the US. The most frequently cited long-term sequela, especially among those who felt coerced to abort, was a continued feeling of guilt. Fantasies about the aborted fetus was the next most frequently mentioned experience. Half of the letter writers referred to their abortions, as "murder" and 44% voiced regret about their decision to abort. Other long-term effects included depression (44%), feelings of loss (31%), shame (27%), and phobic responses to infants (13%). For 42% of these women, the adverse psychological effects of abortion endured over 10 years. Since letter-writers came from a self-selected population group with a known bias against abortion and only negative experiences were solicited, these experiences must be regarded as subjectives and anecdotal. However, they draw attention to the need for methodologically sound studies of a possible prolonged grief syndrome among a small percentage of women who have abortions, especially when coercion is involved.

Testicular cancer (TC) is the most common solid cancer in men between the third and fourth decade of life. Due to successful treatment approaches, TC survivors (TCSs) have long life expectancy, but with numerous potential long-term sequelae, including sexual dysfunction. We investigated predictors of long-term normal sexual function (SF) recovery in TCSs. Sociodemographic, medical, and psychometric data were analyzed in 143 Caucasian-European TCSs, who underwent orchiectomy at a single institution. Health-significant comorbidities were scored with the Charlson Comorbidity Index (CCI). Patients completed the International Index of Erectile Function (IIEF). Statistical models tested the association between predictors (including age at surgery, body mass index, CCI, and adjuvant therapy: radiotherapy [RT], chemotherapy [CT], CT followed by retroperitoneal lymph node dissection [RPLND] and RPLND alone) and the long-term recovery of normal SF (defined as IIEF-erectile function [EF] ≥26, and sexual desire [SD], intercourse satisfaction [IS] orgasmic function [OF], and overall satisfaction [OS] domain scores in the upper tertiles). At a mean follow-up of 86 months, 35 (25.5%) TCSs had erectile dysfunction (ED), with 16 (11.2%) experiencing severe ED. Median time of EF recovery was 60, 60, and 70 months after CT, RT, and RPLND, respectively. Only adjuvant RT emerged as an independent predictor of nonrecovery of normal EF (HR: 0.55, P= 0.01). Neither adjuvant CT nor CT plus RPLND or RPLND alone significantly impaired the recovery of normal erections. Adjuvant therapy was not associated with impaired recovery of normal sexuality as a whole, considering the IIEF-SD, -OF, -IS, and OS domains.

Purpose Surgery, radiotherapy and chemotherapy are the mainstays of cervical cancer treatment. Many patients receive multiple treatment modalities, each with its own long-term effects. Given the high 5 year survival rate for cervical cancer patients, evaluation and improvement of long-term quality of life are essential. Methods Pertinent articles were identified through searches of PubMed for literature published from 1993-2014. We summarize quality of life data from long-term follow up studies of cervical cancer patients. We additionally summarize small group interviews of Hispanic and non-Hispanic cervical cancer survivors regarding social support and coping. Findings Data is varied in terms of the long term impact of treatment on quality of life but consistent in suggesting that patients who receive radiotherapy as part of their treatment have the highest risk of increased long term dysfunction of bladder and bowel, as well as sexual dysfunction and psychosocial consequences. Rigorous investigations regarding long-term consequences of treatment modalities are lacking. Implications Continued work to improve treatment outcomes and survival should also include a focus on reducing adverse long-term side effects. Providing supportive care during treatment, and evaluating the effects of supportive care, may reduce the prevalence and magnitude of long-term sequelae of cervical cancer, which will in turn improve quality of life and quality of care.

Neurotoxicity of drugs of abuse - the case of methylenedioxy amphetamines (MDMA, ecstasy ), and amphetamines

PubMed Central

Gouzoulis-Mayfrank, Euphrosyne; Daumann, Joerg

2009-01-01

Ecstasy (MDMA, 3,4-methylendioxymethamphetamine) and the stimulants methamphetamine (METH, speed) and amphetamine are popular drugs among young people, particularly in the dance scene. When given in high doses both MDMA and the stimulant amphetamines are clearly neurotoxic in laboratory animals. MDMA causes selective and persistent lesions of central serotonergic nerve terminals, whereas amphetamines damage both the serotonergic and dopaminergic systems. In recent years, the question of ecstasy-induced neurotoxicity and possible functional sequelae has been addressed in several studies in drug users. Despite large methodological problems, the bulk of evidence suggests residual alterations of serotonergic transmission in MDMA users, although at least partial recovery may occur after long-term abstinence. However, functional sequelae may persist even after longer periods of abstinence. To date, the most consistent findings associate subtle cognitive impairments with ecstasy use, particularly with memory. In contrast, studies on possible long-term neurotoxic effects of stimulant use have been relatively scarce. Preliminary evidence suggests that alterations of the dopaminergic system may persist even after years of abstinence from METH, and may be associated with deficits in motor and cognitive performance. In this paper, we will review the literature focusing on human studies. PMID:19877498

The incidence of acute kidney injury (AKI) has been increasing over time and is associated with a high risk of short-term death. Previous studies on hospital-acquired AKI have important methodological limitations, especially their retrospective study designs and limited ability to control for potential confounding factors. The Assessment, Serial Evaluation, and Subsequent Sequelae of Acute Kidney Injury (ASSESS-AKI) Study was established to examine how a hospitalized episode of AKI independently affects the risk of chronic kidney disease development and progression, cardiovascular events, death, and other important patient-centered outcomes. This prospective study will enroll a cohort of 1100 adult participants with a broad range of AKI and matched hospitalized participants without AKI at three Clinical Research Centers, as well as 100 children undergoing cardiac surgery at three Clinical Research Centers. Participants will be followed for up to four years, and will undergo serial evaluation during the index hospitalization, at three months post-hospitalization, and at annual clinic visits, with telephone interviews occurring during the intervening six-month intervals. Biospecimens will be collected at each visit, along with information on lifestyle behaviors, quality of life and functional status, cognitive function, receipt of therapies, interim renal and cardiovascular events, electrocardiography and urinalysis. ASSESS-AKI will characterize the short-term and long-term natural history of AKI, evaluate the incremental utility of novel blood and urine biomarkers to refine the diagnosis and prognosis of AKI, and identify a subset of high-risk patients who could be targeted for future clinical trials to improve outcomes after AKI.

Long-term measles-induced immunomodulation increases overall childhood infectious disease mortality

2016-01-01

Immunosuppression after measles is known to predispose people to opportunistic infections for a period of several weeks to months. Using population-level data, we show that measles has a more prolonged effect on host resistance, extending over 2 to 3 years. We find that nonmeasles infectious disease mortality in high-income countries is tightly coupled to measles incidence at this lag, in both the pre- and post-vaccine eras. We conclude that long-term immunologic sequelae of measles drive interannual fluctuations in nonmeasles deaths. This is consistent with recent experimental work that attributes the immunosuppressive effects of measles to depletion of B and T lymphocytes. Our data provide an explanation for the long-term benefits of measles vaccination in preventing all-cause infectious disease. By preventing measles-associated immune memory loss, vaccination protects polymicrobial herd immunity. PMID:25954009

Incomplete recovery from facial palsy has a long-term impact on the quality of life, and medical options for the sequelae of Bell's palsy are limited. Invasive treatments and physiotherapy have been employed to relieve symptoms, but there is limited clinical evidence for their effectiveness. Acupuncture is widely used on Bell's palsy patients in East Asia, but there is insufficient evidence for its effectiveness on Bell's palsy sequelae. The objective is to evaluate the efficacy and safety of acupuncture in patients with sequelae of Bell's palsy. This study consists of a randomized controlled trial with two parallel arms: an acupuncture group and a waitlist group. The acupuncture group will receive acupuncture treatment three times per week for a total of 24 sessions over 8 weeks. Participants in the waitlist group will not receive any acupuncture treatments during this 8 week period, but they will participate in the evaluations of symptoms at the start of the study, at 5 weeks and at 8 weeks after randomization, at which point the same treatment as the acupuncture group will be provided. The primary outcome will be analyzed by the change in the Facial Disability Index (FDI) from baseline to week eight. The secondary outcome measures will include FDI from baseline to week five, House-Brackmann Grade, lip mobility, and stiffness scales.

Endogenous lipoid pneumonia is an uncommon condition. This is a report of a 29-year-old woman diagnosed with endogenous lipoid pneumonia associated with Legionella pneumophila serogroup 1 infection. The patient's endogenous lipoid pneumonia resolved completely after treatment for Legionella pneumophila infection. This suggests that early diagnosis and aggressive treatment of the underlying infection may prevent any long-term sequelae of lipoid pneumonia.

2009-04-01

Recent outbreaks of nephrolithiasis and acute kidney injury among children in China have been linked to ingestion of milk-based infant formula contaminated with melamine. These cases provide evidence in humans for the nephrotoxicity of melamine, which previously had been described only in animals. The consequences of this outbreak are already severe and will likely continue to worsen. Herein we summarize the global impact of the melamine milk contamination, the reemergence of melamine-tainted animal feed, and potential mechanisms of melamine nephrotoxicity. Large-scale epidemiologic studies are necessary to further characterize this disease and to assess its potential long-term sequelae. This epidemic of environmental kidney disease highlights the morbidity associated with adulterated food products available in today's global marketplace and reminds us of the unique vulnerability of the kidney to environmental insults. Melamine is the latest in a growing list of diverse potentially toxic compounds about which nephrologists and other health-care providers responsible for the diagnosis and management of kidney disease must now be aware.

Patients operated on for congenital pulmonary malformations (CPM) have excellent survival rates, but little is known about long-term morbidity. Our aim is to report the sequelae in patients operated on for CPM in infancy and to define factors that may influence their outcome. All patients operated on for major congenital anomalies are followed in a dedicated outpatient program and evaluated at 6, 24, and 48 months of life (corrected for gestational age) and at school age at 4, 6, 8, and 12 years of life. The data are prospectively collected. Patients operated on for CPM and enrolled in the follow-up clinic between January 2004 and December 2010 are compared with a control group of term infants operated on for inguinal hernia, without other major congenital or acquired abnormalities. The two groups were compared for auxological, respiratory, and orthopedic outcome. In the study period, 76 consecutive patients with CPM attended our dedicated follow-up clinic. Eight non-operated patients were excluded from the study. Age at follow-up was 82.0 (56.1-103.7) months in CPM patients and 83.5 (75.2-90.4) months in controls (P = 0.79). Fifty-three patients with CPM (78%) had one or more clinical or radiological abnormality versus six (16%) control patients (OR [95%CI] 16.5 [5.8-47.2]; P < 0.0001). Over 50% of patients with CPM present long-term sequelae, regardless type of malformation. Therefore, long-term follow-up of patients operated on for CPM is recommended. Further studies are needed to define if, in asymptomatic patients, surgery may modify the natural history of CPM.

Objective Systematic review of possible long-term effects of sports-related concussion in retired athletes. Data sources Ten electronic databases. Study selection Original research; incidence, risk factors or causation related to long-term mental health or neurological problems; individuals who have suffered a concussion; retired athletes as the subjects and possible long-term sequelae defined as >10 years after the injury. Data extraction Study population, exposure/outcome measures, clinical data, neurological examination findings, cognitive assessment, neuroimaging findings and neuropathology results. Risk of bias and level of evidence were evaluated by two authors. Results Following review of 3819 studies, 47 met inclusion criteria. Some former athletes have depression and cognitive deficits later in life, and there is an association between these deficits and multiple prior concussions. Former athletes are not at increased risk for death by suicide (two studies). Former high school American football players do not appear to be at increased risk for later life neurodegenerative diseases (two studies). Some retired professional American football players may be at increased risk for diminishment in cognitive functioning or mild cognitive impairment (several studies), and neurodegenerative diseases (one study). Neuroimaging studies show modest evidence of macrostructural, microstructural, functional and neurochemical changes in some athletes. Conclusion Multiple concussions appear to be a risk factor for cognitive impairment and mental health problems in some individuals. More research is needed to better understand the prevalence of chronic traumatic encephalopathy and other neurological conditions and diseases, and the extent to which they are related to concussions and/or repetitive neurotrauma sustained in sports.

Eight hundred and thirteen children who had had whooping cough when under 5 years of age in the 1977-9 epidemic were compared with a control group roughly four and a half years later, each child being matched by age and sex and from the same class in school. The index group showed long term respiratory sequelae of whooping cough--namely, deterioration in lung function, increase in respiratory symptoms, and increased admission to hospital for both upper and lower respiratory conditions. Asthma was significantly more common in the index group, suggesting that asthma was being regarded as a contraindication to pertussis vaccination. Only 3.5% of the asthmatic children in the index group had been vaccinated as against 29.1% of the controls. PMID:3924316

Sequelae of ventral rhinotomy in dogs and cats with inflammatory and neoplastic nasal pathology: a retrospective study.

1996-01-01

The medical records of 58 patients that had undergone ventral rhinotomies were reviewed to determine the long-term outcome and sequelae of this procedure. The signalment, history, and postoperative survival of these patients were found to be similar to other reports in the literature. The deaths of 2 cats immediately postoperatively were attributed to the use of carotid artery tourniquets. Postoperative complications included 1 oronasal fistula, and a persistent mucopurulent or serous discharge in 76% of the patients that had a primary rhinitis before surgery. Ventral rhinotomy was useful as a diagnostic modality for the removal of foreign material and the curettage of focal lesions, and it may be useful in the palliation of nasal tumors in cats.

The Global Ecology and Epidemiology of West Nile Virus

PubMed Central

Rios, Maria

2015-01-01

Since its initial isolation in Uganda in 1937 through the present, West Nile virus (WNV) has become an important cause of human and animal disease worldwide. WNV, an enveloped virus of the genus Flavivirus, is naturally maintained in an enzootic cycle between birds and mosquitoes, with occasional epizootic spillover causing disease in humans and horses. The mosquito vectors for WNV are widely distributed worldwide, and the known geographic range of WNV transmission and disease has continued to increase over the past 77 years. While most human infections with WNV are asymptomatic, severe neurological disease may develop resulting in long-term sequelae or death. Surveillance and preventive measures are an ongoing need to reduce the public health impact of WNV in areas with the potential for transmission. PMID:25866777

Traumatic Alterations in Consciousness: Traumatic Brain Injury

Blyth, Brian J.; Bazarian, Jeffrey J.

2010-01-01

Mild traumatic brain injury (mTBI) refers to the clinical condition of transient alteration of consciousness as a result of traumatic injury to the brain. The priority of emergency care is to identify and facilitate the treatment of rare but potentially life threatening intra-cranial injuries associated with mTBI through the judicious application of appropriate imaging studies and neurosurgical consultation. Although post-mTBI symptoms quickly and completely resolve in the vast majority of cases, a significant number of patients will complain of lasting problems that may cause significant disability. Simple and early interventions such as patient education and appropriate referral can reduce the likelihood of chronic symptoms. Although definitive evidence is lacking, mTBI is likely to be related to significant long-term sequelae such as Alzheimer's disease and other neurodegenerative processes. PMID:20709244

Although peripheral nervous system involvement is common in eosinophilic granulomatosis with polyangiitis (EGPA), central nervous system (CNS) manifestations are poorly described. This study aimed to describe CNS involvement in EGPA. This retrospective, observational, multicenter study included patients with EGPA and CNS involvement affecting cranial nerves, brain and/or spinal cord. We also undertook a systematic literature review. We analyzed 26 personal cases and 62 previously reported cases. At EGPA diagnosis, asthma was noted in 97%, eosinophilia in 98%, peripheral neuropathy in 55% and cardiac involvement in 41%. 38/71 (54%) were ANCA-positive, with a perinuclear-labeling pattern and/or anti-MPO specificity. CNS was involved in 86% at EGPA diagnosis, preceded EGPA in 2%, and occurred during follow-up in 12% after a median of 24months. Main neurological manifestations were ischemic cerebrovascular lesions in 46 (52%), intracerebral hemorrhage and/or subarachnoid hemorrhage in 21 (24%), loss of visual acuity in 28 (33%) (15 with optic neuritis, 9 with central retinal artery occlusion, 4 with cortical blindness), and cranial nerves palsies in 18 (21%), with 25 patients having ≥1 of these clinical CNS manifestations. Among the 81 patients with assessable neurological responses, 43% had complete responses without sequelae, 43% had partial responses with long-term sequelae and 14% refractory disease. After a mean follow-up of 36months, 11 patients died including 5 from intracerebral hemorrhages. EGPA-related CNS manifestations form 4 distinct neurological pictures: ischemic lesions, intracerebral hemorrhages, cranial nerve palsies and loss of visual acuity. Such manifestation should prompt practitioners to consider EGPA in such conditions. Long-term neurological sequelae were common, and intracerebral hemorrhages had the worst prognostic impact.

Chronic Neuropsychological Sequelae of Cholinesterase Inhibitors in the Absence of Structural Brain Damage: Two Cases of Acute Poisoning

PubMed Central

Roldán-Tapia, Lola; Leyva, Antonia; Laynez, Francisco; Santed, Fernando Sánchez

2005-01-01

Here we describe two cases of carbamate poisoning. Patients AMF and PVM were accidentally poisoned by cholinesterase inhibitors. The medical diagnosis in both cases was overcholinergic syndrome, as demonstrated by exposure to cholinesterase inhibitors. The widespread use of cholinesterase inhibitors, especially as pesticides, produces a great number of human poisoning events annually. The main known neurotoxic effect of these substances is cholinesterase inhibition, which causes cholinergic overstimulation. Once AMF and PVM had recovered from acute intoxication, they were subjected to extensive neuropsychological evaluation 3 and 12 months after the poisoning event. These assessments point to a cognitive deficit in attention, memory, perceptual, and motor domains 3 months after intoxication. One year later these sequelae remained, even though the brain magnetic resonance imaging (MRI) and computed tomography (CT) scans were interpreted as being within normal limits. We present these cases as examples of neuropsychological profiles of long-term sequelae related to acute poisoning by cholinesterase inhibitor pesticides and show the usefulness of neuropsychological assessment in detecting central nervous system dysfunction in the absence of biochemical or structural markers.

Long-term outcomes of adults with features of VACTERL association

Raam, Manu S.; Pineda-Alvarez, Daniel E.; Hadley, Donald W.; Solomon, Benjamin D.

2010-01-01

VACTERL association involves the presence of specific congenital, multi-organ malformations that tend to co-occur. Clinical and research efforts typically center on pediatric patients, and there is a scarcity of information in the literature regarding VACTERL-related issues and outcomes in adulthood. We describe here 11 adults with features of VACTERL association ascertained through our research study on the condition. In our cohort of adult patients, approximately 25% of medically significant malformations that are component features of VACTERL association, including 40% of vertebral, 50% of cardiac, and 50% of renal anomalies, were not identified during childhood. Additionally, medical sequelae of many of the primary malformations identified in infancy or early childhood persist or are first reported in adulthood. These sequelae can involve challenging medical and surgical management in adulthood. As most adults with VACTERL association are not specifically followed for VACTERL-related issues, a more uniform diagnostic work-up and a low threshold for investigation of medical sequelae of the primary disorder may enhance the quality of clinical management in these patients.

To assess concussion knowledge of athletes, coaches, and parents/guardians in a community setting and to understand trends/gaps in knowledge among subgroups to tailor efforts toward creating educational interventions. This prospective cross-sectional study involved 262 individuals (142 [55%] female): 115 athletes participating in noncontact and contact sports (ages 13-19 years), 15 coaches, and 132 parents. Recruitment occurred from August 30, 2015, through August 30, 2016, at 3 local high schools. Participants completed a questionnaire developed by the investigators to assess concussion experience and basic knowledge. Females, health care employees, and parents showed stronger concern for potential long-term sequelae of concussion, whereas athletes were most concerned about not being able to return to sport. Those with higher perceived concussion knowledge were slightly older (median age, 42.5 vs 33 years), more educated (college or higher: 42 [70%] vs 100 [50%]), and more likely to be health care workers (22 [37.9%] vs 34 [17.7%]) and scored higher on knowledge questions (average correct: 75.5% vs 60%). Most participants could identify potential concussion sequelae, but only 86 (34.3%) identified a concussion as a brain injury. Of the subgroups, coaches scored highest on knowledge questions. Those with a concussion history tended to consider themselves more knowledgeable but were also less concerned about sequelae. Overall, those with a concussion history scored slightly higher on knowledge questions (average correct: 69.8% vs 61.9%). Participants involved in contact sports were more likely to have had a concussion vs those in noncontact sports (57 [26%] vs 4 [10.3%]). Significant differences in perceived and actual concussion knowledge across different subgroups of study participants involved in high school sports were identified.

Postthrombotic syndrome.

2006-10-01

Despite considerable progress in the diagnosis and treatment of deep vein thrombosis (DVT) of the lower extremities, one of every three patients will develop postthrombotic sequelae within 2 years; these sequelae are severe in approximately 20% of cases and produce considerable socioeconomic consequences. Among factors potentially related to the development of the postthrombotic syndrome (PTS) are older age, obesity, insufficient oral anticoagulant therapy, and recurrent ipsilateral thrombosis. Whether the extent and location of the initial thrombosis are associated with the development of PTS is controversial. Based on recent findings, the lack of vein recanalization within the first 6 months appears to be an important predictor of PTS, whereas the development of transpopliteal venous reflux is not. The diagnosis of PTS can be made on clinical grounds for patients with a history of DVT. The combination of a standardized clinical evaluation with the results of compression ultrasonography and Doppler ultrasound helps diagnose or exclude a previous proximal vein thrombosis. According to the results of recent clinical studies, the prompt administration of adequate compression elastic stockings in patients with symptomatic DVT has the potential to reduce the frequency of late PTS development by half. The management of this condition is demanding and often frustrating. However, when carefully supervised and instructed to wear proper elastic stockings, more than 50% of patients will either remain stable or improve during long-term follow-up. Clinical presentation helps predict the prognosis; the outcome of patients who refer with initially severe manifestations is more favorable than that of patients whose symptoms deteriorate progressively over time.

Abstract Purpose: A number of studies report neurological and cognitive deficits and behavioural disorders in children after surgical treatment for a benign cerebellar tumour. The present study explores functional outcome in adolescents and adults treated for a low-grade cerebellar astrocytoma in childhood. Participants were 18 adolescents and 46 adults treated for low-grade astrocytoma in childhood. Academic achievement, professional status and neurological, cognitive and behavioural disturbances were collected using self-completed and parental questionnaires for adolescents and phone interview for adults. For the adolescent group, a control group filled in the same questionnaires. Mean time lapse from surgery was 7.8 years for adolescents and 12.9 years for adults. Five adults (11%) had major sequelae related to post-operative complications, post-operative mutism and/or brain stem involvement. All the other participants presented close-to-normal academic achievement and normal autonomy, despite a high rate of reported cognitive difficulties and difficulties related to mild neurological sequelae (fine motor skills, balance). The long-term functional outcome of low-grade cerebellar astrocytoma is generally favourable, in the absence of post-operative complications and brain stem involvement. No major impact of neurological deficits, cognitive problems and emotional disorders on academic achievement and independent functioning was observed.

Chronic glomerular and tubular nephrotoxicity is reported in 20-50% and 20-25%, respectively, of children and adolescents treated with ifosfamide and 60-80% and 10-30%, respectively, of those given cisplatin. Up to 20% of children display evidence of chronic glomerular damage after unilateral nephrectomy for a renal tumour. Overall, childhood cancer survivors have a ninefold higher risk of developing renal failure compared with their siblings. Such chronic nephrotoxicity may have multiple causes, including chemotherapy, radiotherapy exposure to kidneys, renal surgery, supportive care drugs and tumour-related factors. These cause a wide range of chronic glomerular and tubular toxicities, often with potentially severe clinical sequelae. Many risk factors for developing nephrotoxicity, mostly patient and treatment related, have been described, but we remain unable to predict all episodes of renal damage. This implies that other factors may be involved, such as genetic polymorphisms influencing drug metabolism. Although our knowledge of the long-term outcomes of chronic nephrotoxicity is increasing, there is still much to learn, including how we can optimally predict or achieve early detection of nephrotoxicity. Greater understanding of the pathogenesis of nephrotoxicity is needed before its occurrence can be prevented.

Transfusion of red blood cells, platelets and plasma is widely used in the management of anemia and coagulopathy in cancer patients undergoing surgery, chemotherapy, and radiation. The decision to transfuse should not be made lightly as exposure to transfused blood, whether from an allogeneic or even autologous source, is not without risk and the long-term effect of blood transfusion on cancer outcomes remains questionable. Recognition of anemia associated with nutritional deficiency should be promptly corrected while avoiding the use of erythropoiesis stimulating agents. Minimizing blood loss and the prompt control of bleeding, coupled with a restrictive transfusion strategy, seem to be a reasonable approach that does not appear to be associated with long-term sequelae. Limiting platelet transfusion to patients with severe hypo-proliferative thrombocytopenia, and implementation of local hemostatic measures, together with the use of fractionated coagulation factor concentrates, as an alternative to frozen plasma transfusion, may reduce the exposure of cancer patients to potentially harmful thrombogenic and pro-inflammatory cellular microparticles. This joint narrative highlights current opinions for minimizing blood usage in patients with cancer. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

Neonatal hypoxic ischemic encephalopathy (HIE) is a devastating condition resulting from a sustained lack of oxygen during birth. The interest in identifying a relevant biomarker of HIE has thrown into limelight the role of protein S100B as a clinical diagnostic marker of hypoxic brain damage in neonates. To evaluate the diagnostic value of protein S100B, measured in umbilical cord blood immediately after birth, as a useful biomarker in the diagnosis of HIE Sarnat stages II-III as well as a marker for long-term mortality and morbidity. Protein S100B was analyzed in cord blood sampled at birth from 13 newborns later diagnosed with stage II-III HIE and compared with 21 healthy controls. S100B concentrations were related to cord artery pH, amplitude-integrated electroencephalography (aEEG), stage of HIE, and death/sequelae up to an age of 6years. Both parametric and non-parametric statistics were used with a two-sided P<0.05 considered significant. The difference in S100B concentration was marginally statistically significant between HIE cases and controls (P=0.056). Cord blood acidosis (P=0.046), aEEG pattern severity (P=0.030), HIE severity (P=0.027), and condition at 6-year follow-up (healthy/permanent sequelae/death; P=0.027) were all related to an increase in S100B concentration. Protein S100B in neonates suffering from HIE stages II-III appeared elevated in umbilical cord blood at birth. The S100B concentrations were positively associated to the severity of disease and the risk of suffering from neurodevelopmental sequelae and even death. Copyright © 2017. Published by Elsevier B.V.

Outcomes after hand and upper extremity transplantation.

2017-05-01

Hand and upper extremity transplantation (HUET) has emerged as the most frequently performed reconstructive procedure in the burgeoning field of vascularized composite allotransplantation (VCA). VCA refers to a form of transplant with multiple tissue types that represents a viable treatment option for devastating injuries where conventional reconstruction would be unable to restore form and function. As hand transplantation becomes increasingly more common, discussions on advantages and disadvantages of the procedure seem to intensify. Despite encouraging functional outcomes, current immunosuppressive regimens with their deleterious side-effect profile remain a major concern for a life-changing but not life-saving type of transplant. In addition, a growing number of recipients with progressively longer follow-up prompt the need to investigate potential long-term sequelae, such as chronic rejection. This review will discuss the current state of HUET, summarizing outcome data on graft survival, motor and sensory function, as well as immunosuppressive treatment. The implications of these findings for VCA in terms of achievements and challenges ahead will then be discussed.

Since ancient Greece, cerebrovascular accidents have been described with no variation. Even today, they are still a catastrophic event in the lives of patients with a high risk of disabling sequelae. Case report of a 56-year male patient with thalamic ischemia. The intervention with integral strategies involving pharmacological management and cognitive interventions was decisive for the satisfactory evolution of the patient. The management of patients with cerebrovascular accidents cannot be limited to the emergency room. Pharmacological advances in programs and cognitive intervention methods provide intervention tools from the very beginning of the stroke thus reducing the impact of long-term sequelae, and consequently enabling a better reintegration of the patient to his family.

The brain and immune system prompt energy shortage in chronic inflammation and ageing.

PubMed

Straub, Rainer H

2017-12-01

Sequelae frequently seen in patients with chronic inflammatory diseases, such as fatigue, depressed mood, sleep alterations, loss of appetite, muscle wasting, cachectic obesity, bone loss and hypertension, can be the result of energy shortages caused by an overactive immune system. These sequelae can also be found in patients with chronic inflammatory diseases that are in remission and in ageing individuals, despite the immune system being less active in these situations. This Perspectives article proposes a new way of understanding situations of chronic inflammation (such as rheumatic diseases) and ageing based on the principles of evolutionary medicine, energy regulation and neuroendocrine-immune crosstalk. A conceptual framework is provided to enable physicians and scientists to better understand the signs and symptoms of chronic inflammatory diseases and long-term disease consequences resulting from physical and mental inactivity.

Mental health and abortion: review and analysis.

PubMed

Ney, P G; Wickett, A R

1989-11-01

This survey of studies which relate to the emotional sequelae of induced abortion, draws attention to the need for more long-term, in-depth prospective studies. The literature to this point finds no psychiatric indications for abortion, and no satisfactory evidence that abortion improves the psychological state of those not mentally ill; abortion is contra-indicated when psychiatric disease is present, as mental ill-health has been shown to be worsened by abortion. Recent studies are turning up an alarming rate of post-abortion complications such as P.I.D., and subsequent infertility. The emotional impact of these complications needs to be studied. Other considerations looked at are the long-term demographic implications of abortion on demand and the effect on the medical professions.

Low carbohydrate diets for the management of type 1 diabetes have been popularised by social media. The promotion of a low carbohydrate diet in lay media is in contrast to published pediatric diabetes guidelines that endorse a balanced diet from a variety of foods for optimal growth and development in children with type 1 diabetes. This can be a source of conflict in clinical practice. We describe a series of 6 cases where adoption of a low carbohydrate diet in children impacted growth and cardiovascular risk factors with potential long-term sequelae. These cases support current clinical guidelines for children with diabetes that promote a diet where total energy intake is derived from balanced macronutrient sources. © 2017 John Wiley & Sons A/S.

To compare the cost-effectiveness of an additional 24-hour inpatient observation for asymptomatic term neonates born to group B streptococcus (GBS)-colonised mothers with adequate intrapartum antibiotic prophylaxis (IAP) after an initial 24-hour in-hospital observation. Cost-effectiveness analysis from a societal perspective. United States. Asymptomatic term neonates born to GBS-colonised mothers with IAP after an initial 24-hour in-hospital observation. Monte Carlo simulation for a decision tree model incorporating the following chance events: development of GBS sepsis during the second 24 hours of life, development of GBS sepsis between 48 hours and 7 days of life, prompt versus delayed treatment for sepsis, neonatal mortality and long-term health sequelae. Expected cost and quality-adjusted life years (QALYs), Incremental cost-effectiveness ratio (ICER). Delayed, versus early, hospital discharge results in similar mean expected QALYs, but substantially higher expected cost. The mean difference in QALY is 0.00016 (95% CI 0.00005-0.00040), whereas the mean difference in cost is $1170.96 (95% CI $750.13-1584.32). The ICER is estimated to be $9,771,520.87 per QALY (95% CI $2,573,139.89-24,407,017.82). The proportion of early-onset GBS that develops during the second 24 hours of life, the cost of 24 hours of inpatient observation, and the probability of long-term sequelae following prompt versus delayed treatment play important roles in determining the cost-effectiveness of delayed hospital discharge. Cost-effectiveness analysis suggests that with adequate IAP, discharging asymptomatic term neonates to home after 24 hours is the preferred approach compared with 48 hours inpatient observation. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

Systematic review of possible long-term effects of sports-related concussion in retired athletes. Ten electronic databases. Original research; incidence, risk factors or causation related to long-term mental health or neurological problems; individuals who have suffered a concussion; retired athletes as the subjects and possible long-term sequelae defined as > 10 years after the injury. Study population, exposure/outcome measures, clinical data, neurological examination findings, cognitive assessment, neuroimaging findings and neuropathology results. Risk of bias and level of evidence were evaluated by two authors. Following review of 3819 studies, 47 met inclusion criteria. Some former athletes have depression and cognitive deficits later in life, and there is an association between these deficits and multiple prior concussions. Former athletes are not at increased risk for death by suicide (two studies). Former high school American football players do not appear to be at increased risk for later life neurodegenerative diseases (two studies). Some retired professional American football players may be at increased risk for diminishment in cognitive functioning or mild cognitive impairment (several studies), and neurodegenerative diseases (one study). Neuroimaging studies show modest evidence of macrostructural, microstructural, functional and neurochemical changes in some athletes. Multiple concussions appear to be a risk factor for cognitive impairment and mental health problems in some individuals. More research is needed to better understand the prevalence of chronic traumatic encephalopathy and other neurological conditions and diseases, and the extent to which they are related to concussions and/or repetitive neurotrauma sustained in sports. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The chronic effects of cannabis on memory in humans: a review.

PubMed

Solowij, Nadia; Battisti, Robert

2008-01-01

Memory problems are frequently associated with cannabis use, in both the short- and long-term. To date, reviews on the long-term cognitive sequelae of cannabis use have examined a broad range of cognitive functions, with none specifically focused on memory. Consequently, this review sought to examine the literature specific to memory function in cannabis users in the nontoxicated state with the aim of identifying the existence and nature of memory impairment in cannabis users and appraising potentially related mediators or moderators. Literature searches were conducted to extract well-controlled studies that investigated memory function in cannabis users outside of the acute intoxication period, with a focus on reviewing studies published within the past 10 years. Most recent studies have examined working memory and verbal episodic memory and cumulatively, the evidence suggests impaired encoding, storage, manipulation and retrieval mechanisms in long-term or heavy cannabis users. These impairments are not dissimilar to those associated with acute intoxication and have been related to the duration, frequency, dose and age of onset of cannabis use. We consider the impact of not only specific parameters of cannabis use in the manifestation of memory dysfunction, but also such factors as age, neurodevelopmental stage, IQ, gender, various vulnerabilities and other substance-use interactions, in the context of neural efficiency and compensatory mechanisms. The precise nature of memory deficits in cannabis users, their neural substrates and manifestation requires much further exploration through a variety of behavioural, functional brain imaging, prospective and genetic studies.

Vitiligo iridis and glaucoma: a rare sequelae of small pox.

Vitiligo iridis refers to focal areas of iris atrophy as sequelae of small pox infection. We report a series of patients with unilateral vitiligo iridis, some of whom presented with secondary open-angle glaucoma. Three patients with vitiligo iridis underwent a comprehensive ophthalmic examination including intraocular pressure (IOP) measurement, slit lamp biomicroscopy, gonioscopy, and fundus evaluation. Patients' facial features were also documented and photographed. All patients were in their sixth decade. Two out the three had elevated IOP (52 mm Hg and 36 mm Hg) in the same eye as vitiligo iridis, at initial presentation. Gonioscopy showed patchy iris hyperpigmentation and fundus evaluation showed glaucomatous optic disc changes in the involved eye. One patient responded favourably to topical antiglaucoma medications, whereas the other was taken up for combined phacoemulsification-trabeculectomy with good results. The third patient had normal IOP in the involved eye. All three patients gave a history of small pox in childhood and had pitted facial scars typical of previous small pox infection. Vitiligo iridis may be associated with the secondary glaucoma as a long-term sequelae of small pox. It may be prudent to periodically follow-up such patients for development of raised IOP in the future.

A rapidly expanding scientific literature supports the frequent co-occurrence of sleep and circadian disturbances following mild traumatic brain injury (mTBI). Although many questions remain unanswered, the preponderance of evidence suggests that sleep and circadian disorders can result from mTBI. Among those with mTBI, sleep disturbances and clinical sleep and circadian disorders contribute to the morbidity and long-term sequelae across domains of functional outcomes and quality of life. Specifically, along with deterioration of neurocognitive performance, insufficient and disturbed sleep can precede, exacerbate, or perpetuate many of the other common sequelae of mTBI, including depression, post-traumatic stress disorder, and chronic pain. Further, sleep and mTBI share neurophysiologic and neuroanatomic mechanisms that likely bear directly on success of rehabilitation following mTBI. For these reasons, focus on disturbed sleep as a modifiable treatment target has high likelihood of improving outcomes in mTBI. Here, we review relevant literature and present a research agenda to 1) advance understanding of the reciprocal relationships between sleep and circadian factors and mTBI sequelae and 2) advance rapidly the development of sleep-related treatments in this population.

The long-term sequelae of Kawasaki disease (KD) are based on the coronary complications. Because KD causes generalized vasculitis, with documented aneurysms in the femoral, iliac, renal, axillary, and brachial arteries, the aim of this study was to assess the biophysical properties of the aorta (BPA) after KD. The BPA are biometric measurements representing vascular structural and dynamic changes in response to cardiac work. Anthropometric and echocardiographic measurements of the aorta in a series of patients with KD were compared with those of healthy subjects. The BPA were calculated noninvasively by extrapolating previously validated equations that were conceived for invasive measurements. Because BPA vary with body habitus, control subjects were used to normalize BPA parameters for height to compute BPA Z-score equations. Between June 2007 and February 2010, BPA were recorded in 57 patients with KD >1 year after the onset of the disease, 45 without and 12 with coronary artery sequelae. The mean intervals between the acute onset of KD and enrollment were 10.0 ± 5.0 and 5.8 ± 4.5 years for patients with and without coronary artery sequelae, respectively (P = .008). Patients with KD with coronary artery sequelae had significantly altered Z scores of aortic diameter modulation, Peterson's elastic modulus, and β stiffness index (P = .001-.016). Patients with KD without coronary artery sequelae also exhibited altered elasticity, stiffness, and pulse-wave velocity (P = .001-.026). Altered BPA after KD are detectible despite apparent resolution of acute vasculitis. Future directions toward determining multilevel and multilayer vascular impact, including vascular autonomous homeostasis, require thorough investigation.

Abstract Hypoglycemia commonly occurs in patients who are being treated for diabetes. In some cases, these patients suffer from severe hypoglycemia that requires medical assistance and which can unfortunately result in long-term disabilities. Therefore, we investigated risk factors associated with severe hypoglycemia requiring medical assistance (HMA) and the resulting neurological sequelae in patients with diabetes. This investigation was a case–control study that assessed 129 patients with diabetes and documented hypoglycemia from a single tertiary hospital between February 2013 and May 2015. They were treated with oral hypoglycemic agents alone (54%) or with insulin with/without oral hypoglycemic agents (46%). If a patient with diabetes visited the emergency department due to hypoglycemia, this was defined as HMA. The control group was composed of patients with documented, nonsevere hypoglycemia who visited the outpatient clinic during the same period. The degree of neurological disability in the HMA patients was measured using the modified Rankin Scale. A multivariate analysis revealed that independent risk factors of HMA were associated with a lack of the self-monitoring of blood glucose (SMBG) and previous episodes of severe hypoglycemia. In the HMA group, 15 patients (22%) had neurological sequelae at the time of discharge. Patients with neurological sequelae were older than those without sequelae (74.3 years vs 65.8 years, P = 0.006) and had increased psychological evidence of disorders such as insomnia, dementia, and depression (40% vs 11%, P = 0.017). Patients with sequelae were also more likely to live in rural areas (47% vs 19%, P = 0.04) and to have a longer time from last seen normal till glucose administration (5.2 hours vs 1.6 hours, P = 0.027). In the present study, absence of SMBG and previous severe hypoglycemic episodes were independent risk factors of HMA and patients with an older age, a psychological disorder, a rural residence, and a prolonged duration of hypoglycemia had higher risks of neurological sequelae. Therefore, the present findings suggest that physicians should aim to prevent hypoglycemia in patients with a history of hypoglycemia and provide education for these patients regarding regular SMBG.

The author discusses trauma, particularly in relation to childhood events, as well as one of its possible sequelae, soul murder (Shengold 1989, 1999). Negative interactions with parental figures can have long-term implications for the developing child, sometimes persisting into adulthood, and yet even the most loving parents cannot always behave toward the child in an optimal manner. The profound effect of change on the human psyche is also discussed, and two clinical vignettes are presented to illustrate the author's points.

Psychosocial issues affecting crews during long-duration international space missions.

Psychosocial issues can negatively impact on crew performance and morale during long-duration international space missions. Major psychosocial factors that have been described in anecdotal reports from space and in studies from analog situations on Earth include: 1) crew heterogeneity due to gender differences, cultural issues, and work experiences and motivations; 2) language and dialect variations; and 3) task versus supportive leadership roles. All of these factors can lead to negative sequelae, such as intra-crew tension and cohesion disruptions. Specific sequelae that can result from single factors include subgrouping and scapegoating due to crew heterogeneity; miscommunication due to major or subtle language differences; and role confusion, competition, and status leveling due to inappropriate leadership role definition. It is time to conduct research exploring the impact of these psychosocial factors and their sequelae on space crews during actual long-duration international space missions.

1991-02-01

Since 1984, a consecutive series of patients with cervical spondylotic myelopathy has been treated by central corpectomy and strut grafting. This report focuses on 40 cases operated on between 1984 and 1987 and followed from 2 to 5 years. The perioperative complication rate was 47.5%, with a 7.5% incidence of persistent sequelae: severe C-5 radiculopathy in one patient, swallowing dysfunction in one, and hypoglossal nerve palsy in one. No single factor (age, duration of symptoms, or severity of myelopathy) was absolutely predictive of outcome; however, syndromes of short duration had the best likelihood of cure. Similar outcomes were associated, individually, with long duration of symptoms, age over 70 years, and severe myelopathy. After factoring a 5% regression of improvement, the long-term cure rate was 57.5% and the failure rate was 15%. Myelopathy worsening was not documented.

Hematopoietic cell transplantation (HCT) is a potentially curative treatment for children and adults with malignant and non-malignant diseases. Despite increasing survival rates, long-term morbidity following HCT is substantial. Neurocognitive dysfunction is a serious cause of morbidity, yet little is known about neurocognitive dysfunction following HCT. To address this gap, collaborative efforts of the Center for International Blood and Marrow Transplant Research and the European Society for Blood and Marrow Transplantation undertook an expert review of neurocognitive dysfunction following HCT. In this review, we define what constitutes neurocognitive dysfunction, characterize its risk factors and sequelae, describe tools and methods to assess neurocognitive function in HCT recipients, and discuss possible interventions for HCT patients with this condition. This review aims to help clinicians understand the scope of this health-related problem, highlight its impact on well-being of survivors, and to help determine factors that may improve identification of patients at risk for declines in cognitive functioning after HCT. In particular, we review strategies for preventing and treating neurocognitive dysfunction in HCT patients. Lastly, we highlight the need for well-designed studies to develop and test interventions aimed at preventing and improving neurocognitive dysfunction and its sequelae following HCT. PMID:29343837

Breast-Feeding Friendly, but Not Formula Averse.

Lewis, Juanita

2017-11-01

Breast-feeding is the optimal source of newborn nutrition in term infants and is associated with multiple short- and long-term health benefits. Establishment of breast-feeding may be difficult in a small subset of mothers, which can lead to adverse consequences in the newborn. Some of the consequences of suboptimal nutritional provision to the newborn, such as severe hyperbilirubinemia and breast-feeding-associated hypernatremic dehydration, can have devastating and long-lasting sequelae. Timely identification of mothers and newborns at risk for developing these complications is necessary to avoid significant morbidity and mortality. In these cases, the judicious use of formula supplementation may be considered. However, more studies are necessary to develop comprehensive formula supplementation criteria and guidelines for pediatric medical providers. [Pediatr Ann. 2017;46(11):e402-e408.].

Acupuncture for sequelae of Bell's palsy: a randomized controlled trial protocol

PubMed Central

2011-01-01

Objective Incomplete recovery from facial palsy has a long-term impact on the quality of life, and medical options for the sequelae of Bell's palsy are limited. Invasive treatments and physiotherapy have been employed to relieve symptoms, but there is limited clinical evidence for their effectiveness. Acupuncture is widely used on Bell's palsy patients in East Asia, but there is insufficient evidence for its effectiveness on Bell's palsy sequelae. The objective is to evaluate the efficacy and safety of acupuncture in patients with sequelae of Bell's palsy. Method/Design This study consists of a randomized controlled trial with two parallel arms: an acupuncture group and a waitlist group. The acupuncture group will receive acupuncture treatment three times per week for a total of 24 sessions over 8 weeks. Participants in the waitlist group will not receive any acupuncture treatments during this 8 week period, but they will participate in the evaluations of symptoms at the start of the study, at 5 weeks and at 8 weeks after randomization, at which point the same treatment as the acupuncture group will be provided. The primary outcome will be analyzed by the change in the Facial Disability Index (FDI) from baseline to week eight. The secondary outcome measures will include FDI from baseline to week five, House-Brackmann Grade, lip mobility, and stiffness scales.

Acute kidney injury in the fetus and neonate

Nada, Arwa; Bonachea, Elizabeth M.; Askenazi, David

2017-01-01

SUMMARY Acute kidney injury (AKI) is an under-recognized morbidity of neonates; the incidence remains unclear due to the absence of a unified definition of AKI in this population and because previous studies have varied greatly in screening for AKI with serum creatinine and urine output assessments. Premature infants may be born with less than half of the nephrons compared with term neonates, predisposing them to chronic kidney disease (CKD) early on in life and as they age. AKI can also lead to CKD, and premature infants with AKI may be at very high risk for long-term kidney problems. AKI in neonates is often multifactorial and may result from prenatal, perinatal, or postnatal insults as well as any combination thereof. This review focuses on the causes of AKI, the importance of early detection, the management of AKI in neonates, and long-term sequela of AKI in neonates. PMID:28034548

Purpose: To report the Institut Gustave Roussy brachytherapy (BT) experience in the management of vulval and vaginal rhabdomyosarcoma with special emphasis on long-term outcome. Patients and Methods: Between 1971 and 2005, the data concerning 39 girls who had undergone BT as a part of their treatment were retrospectively analyzed. Of the 39 girls, 20 had been treated before 1990, when the BT volume encompassed the initial tumor extension. After 1990, only residual disease was included in the BT volume. Side effects were classified using the Common Terminology Criteria for Adverse Events, version 3.0. Results: The median age was 16.3 monthsmore » at diagnosis. Vaginal or vulvar rhabdomyosarcoma was diagnosed in 26 and 6 patients, respectively. The median follow-up was 8.4 years. The 5-year overall survival rate was 91%. Of the 39 patients, 6 developed a relapse. Of the 20 patients treated before 1990, 6 experienced Grade 1-2 renal/genitourinary function symptoms and 75% developed sequelae, in the form of vaginal or urethral sclerosis or stenosis. Four patients received follow-up treatment for psychological disorders. Of the 19 patients treated after 1990, 2 developed acute side effects, with maximal Grade 1-2 renal/genitourinary function symptoms, and 20% developed vaginal or urethral sclerosis or stenosis. Two cases of psychological disturbances were also documented. Conclusion: Reducing the BT volume coverage, better indications for surgery, and more efficient chemotherapy, all combined within a multidisciplinary approach, tended to improve results in terms of both survival and long-term sequelae.« less

Reconstruction of periorbital soft tissue defects.

Berli, Jens U; Merbs, Shannath L; Grant, Michael P

2014-10-01

Because of the complex anatomy and fine mechanics of the periorbital soft tissues, the reconstruction of this region can be particularly daunting. Through a structured assessment of the defect, based on subunit analysis and thorough understanding of the surgical layers, we believe to allow the reconstructive surgeon to develop an algorithmic approach to these complex problems. The sequela of a suboptimal reconstruction do not only result in an inferior aesthetic result, but also have the potential for long-term functional problems such as epiphora, dry eye, ptosis, eyelid retraction, and thus requiring secondary surgery. There is no better time to aim for a perfect reconstruction than at the time of the initial surgery. In this chapter, we hope to encourage the reader to strengthen and recapitulate these analytical skills and present the most commonly used and studied techniques to help achieve a reproducible functional and aesthetically appealing result.

Vascular Neural Network phenotypic transformation after traumatic injury: potential role in long-term sequelae

PubMed Central

Badaut, J.; Bix, G.J.

2014-01-01

The classical neurovascular unit (NVU), composed primarily of endothelium, astrocytes and neurons, could be expanded to include smooth muscle and perivascular nerves present in both the up and down stream feeding blood vessels (arteries and veins). The extended NVU, which can be defined as the vascular neural network (VNN), may represent a new physiological unit to consider for therapeutic development in stroke, traumatic brain injury, and other brain disorders [1]. This review is focused on traumatic brain injury and resultant post-traumatic changes in cerebral blood-flow, smooth muscle cells, matrix, BBB structures and function and the association of these changes with cognitive outcomes as described in clinical and experimental reports. We suggest that studies characterizing TBI outcomes should increase their focus on changes to the VNN as this may yield meaningful therapeutic targets to resolve post-traumatic dysfunction.

Management of anthracycline extravasation into the pleural space.

PubMed

Chang, Rachael; Murray, Nick

2016-10-01

Anthracycline extravasation is a feared complication of intravenous (i.v.) chemotherapy due to the tissue toxicity of this group of drugs. We describe a 54-year-old woman with history of stage IIIa breast cancer, receiving adjuvant chemotherapy consisting of doxorubicin and cyclophosphamide. The chemotherapy was administered through a Poweport ® device, the position of which was confirmed with fluoroscopy and function confirmed by flushing the line. Urgent intervention was required as patient was symptomatic and experienced severe right-sided pleuritic chest pain. Radiology also confirmed the extravasation of doxorubicin into the pleural space. Surgical washout of the pleural space and 3 days therapy with i.v. dexrazoxane were carried out to prevent tissue damage and long-term sequelae. Use of dexrazoxane should always be considered following intra-pleural extravasation because of its potential efficacy and reasonable tolerability. However, the best approach to extravasation injury is prevention by systematic implementation of careful, standardized, evidence-based administration techniques.

Drug interaction of levothyroxine with infant colic drops.

Balapatabendi, Mihirani; Harris, David; Shenoy, Savitha D

2011-09-01

Infacol (Forest Laboratories UK, Kent, UK) is a widely available over-the-counter preparation used to relieve colic symptoms in neonates and infants. The active ingredient is simeticone. No drug interactions with simeticone are documented in the current summary of product characteristics. The authors report the case of an infant with confirmed congenital hypothyroidism on levothyroxine who experienced a possible drug interaction with simeticone. Despite adequate levothyroxine dosage, thyroid stimulating hormone (TSH) was high, suggesting undertreatment. Questioning revealed the child was taking Infacol drops before feeds while on levothyroxine. The colic drops were immediately discontinued and TSH promptly normalised with a reduction in thyroxine requirement to an age appropriate dosage. Drug interaction of thyroxine with simeticone has not been reported previously and is not listed in the British National Formulary for Children. Clinicians and parents need to be aware of this interaction to avoid unnecessary undertreatment and prevent potential long-term neurological sequelae.

The Neurotoxicity of General Anesthetic Drugs: Emphasis on the Extremes of Age.

PubMed

Biddle, Chuck; Ford, Vincent

2017-01-01

A substantial body of research suggests that anesthetic exposure to patients who are very young or very old may impair cognitive, behavioral, and emotional development or recovery. In lower animal models of pre- and postnatal age, anesthetic exposure may impact inflammation, synaptogenesis, neuronal apoptosis, and glial cell development. To date, research in humans is inconclusive regarding the long-term cognitive and behavioral sequelae of general anesthesia in the young child. In older adults, postoperative cognitive dysfunction and cognitive delirium are identified as markers of anesthetic neurotoxicity. Existing neurological degenerative processes and other comorbidities in combination with the stress of surgery make evaluating the independent impact of anesthetic exposure difficult. Advances in research, imaging, and partnerships have enhanced the potential for understanding the impact of anesthetic exposure. In both populations, the resulting data and limitations faced in initial research efforts are catalysts for current prospective studies.

Emerging technologies in point-of-care molecular diagnostics for resource-limited settings.

PubMed

Peeling, Rosanna W; McNerney, Ruth

2014-06-01

Emerging molecular technologies to diagnose infectious diseases at the point at which care is delivered have the potential to save many lives in developing countries where access to laboratories is poor. Molecular tests are needed to improve the specificity of syndromic management, monitor progress towards disease elimination and screen for asymptomatic infections with the goal of interrupting disease transmission and preventing long-term sequelae. In simplifying laboratory-based molecular assays for use at point-of-care, there are inevitable compromises between cost, ease of use and test performance. Despite significant technological advances, many challenges remain for the development of molecular diagnostics for resource-limited settings. There needs to be more advocacy for these technologies to be applied to infectious diseases, increased efforts to lower the barriers to market entry through streamlined and harmonized regulatory approaches, faster policy development for adoption of new technologies and novel financing mechanisms to enable countries to scale up implementation.

Life and death decisions for incompetent patients: determining best interests--the Irish perspective.

To determine whether healthcare providers apply the best interest principle equally to different resuscitation decisions. An anonymous questionnaire was distributed to consultants, trainees in neonatology, paediatrics, obstetrics and 4th medical students. It examined resuscitation scenarios of critically ill patients all needing immediate resuscitation. Outcomes were described including survival and potential long-term sequelae. Respondents were asked whether they would intubate, whether resuscitation was in the patients best interest, would they accept surrogate refusal to initiate resuscitation and in what order they would resuscitate. The response rate was 74%. The majority would wish resuscitation for all except the 80-year-old. It was in the best interest of the 2-month-old and the 7-year-old to be resuscitated compared to the remaining scenarios (p value <0.05 for each comparison). Approximately one quarter who believed it was in a patient best interests to be resuscitated would nonetheless accept the family refusing resuscitation. Medical students were statistically more likely to advocate resuscitation in each category. These results suggest resuscitation is not solely related to survival or long-term outcome and the best interest principle is applied differently, more so at the beginning of life. © 2010 The Author(s)/Acta Paediatrica © 2010 Foundation Acta Paediatrica.

Anxiety and depression in long-term testicular germ cell tumor survivors.

Vehling, S; Mehnert, A; Hartmann, M; Oing, C; Bokemeyer, C; Oechsle, K

2016-01-01

Despite a good prognosis, the typically young age at diagnosis and physical sequelae may cause psychological distress in germ cell tumor survivors. We aimed to determine the frequency of anxiety and depression and analyze the impact of demographic and disease-related factors. We enrolled N=164 testicular germ cell tumor survivors receiving routine follow-up care at the University Cancer Center Hamburg and a specialized private practice (mean, 11.6 years after diagnosis). Patients completed the Generalized Anxiety Disorder Screener-7, the Patient Health Questionnaire-9 and the Memorial Symptom Assessment Scale-Short Form. We found clinically significant anxiety present in 6.1% and depression present in 7.9% of survivors. A higher number of physical symptoms and having children were significantly associated with higher levels of both anxiety and depression in multivariate regression analyses controlling for age at diagnosis, cohabitation, socioeconomic status, time since diagnosis, metastatic disease and relapse. Younger age at diagnosis and shorter time since diagnosis were significantly associated with higher anxiety. Although rates of clinically relevant anxiety and depression were comparably low, attention toward persisting physical symptoms and psychosocial needs related to a young age at diagnosis and having children will contribute to address potential long-term psychological distress in germ cell tumor survivors.

The role of tuberculosis as a public health care priority and the availability of diagnostic tools to evaluate functional status (spirometry, plethysmography, and DLCO determination), arterial blood gases, capacity to perform exercise, lesions (chest X-ray and CT), and quality of life justify the effort to consider what needs to be done when patients have completed their treatment. To our knowledge, no review has ever evaluated this topic in a comprehensive manner. Our objective was to review the available evidence on this topic and draw conclusions regarding the future role of the "post-tuberculosis treatment" phase, which will potentially affect several million cases every year. We carried out a non-systematic literature review based on a PubMed search using specific keywords (various combinations of the terms "tuberculosis", "rehabilitation", "multidrug-resistant tuberculosis", "pulmonary disease", "obstructive lung disease", and "lung volume measurements"). The reference lists of the most important studies were retrieved in order to improve the sensitivity of the search. Manuscripts written in English, Spanish, and Russian were selected. The main areas of interest were tuberculosis sequelae following tuberculosis diagnosis and treatment; "destroyed lung"; functional evaluation of sequelae; pulmonary rehabilitation interventions (physiotherapy, long-term oxygen therapy, and ventilation); and multidrug-resistant tuberculosis.The evidence found suggests that tuberculosis is definitively responsible for functional sequelae, primarily causing an obstructive pattern on spirometry (but also restrictive and mixed patterns), and that there is a rationale for pulmonary rehabilitation. We also provide a list of variables that should be discussed in future studies on pulmonary rehabilitation in patients with post-tuberculosis sequelae. RESUMO O papel da tuberculose como uma prioridade de saúde pública e a disponibilidade de ferramentas diagnósticas para avaliar o estado funcional (espirometria, pletismografia e DLCO), a gasometria arterial, a capacidade de realizar exercícios, as lesões (radiografia de tórax e TC) e a qualidade de vida justificam o esforço de se considerar o que deve ser feito quando os pacientes completam seu tratamento. Até onde sabemos, nenhuma revisão avaliou esse tópico de forma abrangente. Nosso objetivo foi revisar as evidências disponíveis e obter algumas conclusões sobre o futuro papel da fase de "tratamento pós-tuberculose", que irá potencialmente impactar milhões de casos todos os anos. Realizou-se uma revisão não sistemática da literatura tendo como base uma pesquisa no PubMed usando palavras-chave específicas (várias combinações dos termos "tuberculose", "reabilitação", "tuberculose multirresistente", "doença pulmonar", "doença pulmonar obstrutiva", e "medidas de volume pulmonar"). As listas de referências dos artigos principais foram recuperadas para melhorar a sensibilidade da busca. Foram selecionados manuscritos escritos em inglês, espanhol e russo. As principais áreas de interesse foram sequelas de tuberculose após diagnóstico e tratamento; "pulmão destruído"; avaliação funcional das sequelas; intervenções de reabilitação pulmonar (fisioterapia, oxigenoterapia de longo prazo e ventilação); e tuberculose multirresistente. As evidências encontradas sugerem que a tuberculose é definitivamente responsável por sequelas funcionais, principalmente causando um padrão obstrutivo na espirometria (mas também padrões restritivos e mistos) e que há razão para a reabilitação pulmonar. Fornecemos também uma lista de variáveis a serem discutidas em futuros estudos sobre reabilitação pulmonar em pacientes com sequelas pós-tuberculose.

The authors compared the neurologic, neuropsychological, and neuroradiologic status of military compressed-air divers without a history of neurologic decompression illness and controls. No gross differences in the neuropsychometric test results or abnormal neurologic findings were found. There was no correlation between test results, diving experience, and number and size of cerebral MRI lesions. Prevalence of cerebral lesions was not increased in divers. These results suggest that there are no long-term CNS sequelae in military divers if diving is performed under controlled conditions.

This study reports the complications observed in children with long bone fractures treated using Elastic Stable Intramedullary Nailing (ESIN). One hundred and sixty-four (n = 164) fractures in 160 patients under the age of 16 years formed the basis of our review. This included 108 boys and 52 girls with the median age of 11 years and median follow up of 7.5 months. The analysis included fractures of the radius/ulna, humerus, femur and tibia. All pathological fractures were excluded. In this series 54 patients (34%) had complications however majority of these were minor complications with irritation due to prominent nail ends being the commonest complication. No long-term sequelae were encountered in our patients. PMID:24403743

Background Treatment of testicular germ cell cancer constitutes a major success story in modern oncology. Today, the vast majority of patients are cured by a therapeutic strategy using one or more highly effective components including surgery (orchiectomy), radiotherapy and/or chemotherapy. However, the excellent cancer specific survival comes at considerable costs, as individuals with a history of germ cell cancer experience serious long-term complications, including markedly increased risk of cardiovascular morbidities and premature cardiovascular death. The factors responsible, as well as their mode of action, are not fully understood and there is a lack of knowledge concerning optimal evidence-based long-term follow-up strategies. Results Here, we present the growing body of evidence suggesting that germ cell cancer patients as a consequence of the different treatment components, are subjected to toxicities, which individually, and synergistically, can cause physiological impairments leading to sub-clinical or clinical cardiovascular disorders the ‘multiple-hit hypothesis’). Furthermore, we discuss the efficacy and utility of structured exercise training to ameliorate treatment-induced cardiovascular dysfunction to prevent premature onset of clinical cardiovascular disease in germ cell cancer survivors, with a view towards highlighting future directions of exercise-based survivorship research in the germ cell cancer setting. Conclusion Since exercise training may have the potential to ameliorate and/or reverse long-term cardiovascular disease sequelae in germ cell cancer survivors, a strong rationale exists for the promotion of exercise-oncology research in this setting, in order to provide exercise-recommendations for optimal germ cell cancer survivorship.

Few studies have examined the neuropsychological sequelae associated with end-stage pulmonary disease. Neuropsychological data are presented for 47 patients with end-stage chronic obstructive pulmonary disease (COPD) who were being evaluated as potential candidates for lung transplantation. Although patients exhibited a diversity of neurocognitive deficits, their highest frequencies of impairment were found on the Selective Reminding Test (SRT). Specifically, over 50% of the patients completing the SRT exhibited impaired immediate free recall and consistent long-term retrieval deficits, while more than 44% of these individuals displayed deficient long-term retrieval. Deficient SRT long-term storage strategies, cued recall, and delayed recall were exhibited by between 26% and 35% of these patients, while more than 32% of this sample displayed elevated numbers of intrusion errors. Over 31% of the patients completing the Wisconsin Card Sorting Test (WCST) failed to achieve the expected number of categories on this measure, while more than 23% of these individuals demonstrated elevated numbers of perseverative errors and total errors. Clinically notable frequencies of impairment (greater than 20% of the sample) were also found on the Trail Making Test (TMT): Part B and the Wechsler Memory Scale-R (WMS-R) Visual Reproduction II subtest. Minnesota Multiphasic Personality Inventory-2 (MMPI-2) personality assessments indicated that patients were experiencing a diversity of somatic complaints and that they may have been functioning at a reduced level of efficiency. These findings are discussed in light of patients’ end-stage COPD and factors possibly contributing to their neuropsychological test performances. Implications for clinical practice and future research are also included. PMID:14589783

Child maltreatment: pathway to chronic and long-term conditions?

The manifesto Start Well, Live Better by the UK Faculty of Public Health (Start Well, Live Better-A Manifesto for the Public's Health. London: UK Faculty of Public Health, 2014) sets out 12 compelling priorities for the protection of people's health. The focus of this document is preventative, calling for a comprehensive strategy to target a wide-ranging set of challenges to public health; however, it fails to mention child maltreatment and its negative impact on long-term health outcomes. In this article, we explore the long-term negative consequences of child maltreatment and how these can be conceptually aligned with four different characteristics of long-term health conditions. We suggest that situating child maltreatment within a long-term conditions framework could have significant advantages and implications for practice, policy and research, by strengthening a commitment across disciplines to apply evidence-based principles linked with policy and evaluation and recognizing the chronic effects of maltreatment to concentrate public, professional and government awareness of the extent and impact of the issue. We argue that a public health approach is the most effective way of focusing preventative efforts on the long-term sequelae of child maltreatment and to foster cooperation in promoting children's rights to grow and develop in a safe and caring environment free from violence and abuse. © The Author 2015.

Studies investigating long-term health conditions in patients with craniopharyngioma are limited by short follow-up durations and generally do not compare long-term health effects according to initial craniopharyngioma treatment approach. In addition, studies comparing long-term health conditions between patients with childhood- and adult-onset craniopharyngioma report conflicting results. The objective of this study was to analyse a full spectrum of long-term health effects in patients with craniopharyngioma according to initial treatment approach and age group at craniopharyngioma presentation. Cross-sectional study based on retrospective data. We studied a single-centre cohort of 128 patients with craniopharyngioma treated from 1980 onwards (63 patients with childhood-onset disease). Median follow-up since craniopharyngioma presentation was 13 years (interquartile range: 5-23 years). Initial craniopharyngioma treatment approaches included gross total resection ( n  = 25), subtotal resection without radiotherapy ( n  = 44), subtotal resection with radiotherapy ( n  = 25), cyst aspiration without radiotherapy ( n  = 8), and 90 Yttrium brachytherapy ( n  = 21). Pituitary hormone deficiencies (98%), visual disturbances (75%) and obesity (56%) were the most common long-term health conditions observed. Different initial craniopharyngioma treatment approaches resulted in similar long-term health effects. Patients with childhood-onset craniopharyngioma experienced significantly more growth hormone deficiency, diabetes insipidus, panhypopituitarism, morbid obesity, epilepsy and psychiatric conditions compared with patients with adult-onset disease. Recurrence-/progression-free survival was significantly lower after initial craniopharyngioma treatment with cyst aspiration compared with other therapeutic approaches. Survival was similar between patients with childhood- and adult-onset craniopharyngioma. Long-term health conditions were comparable after different initial craniopharyngioma treatment approaches and were generally more frequent in patients with childhood- compared with adult-onset disease. © 2017 European Society of Endocrinology.

Current management of long-term survivors of biliary atresia: over 40 years of experience in a single center and review of the literature.

Owing to several therapeutic advancements, more patients with biliary atresia now survive into adulthood while retaining their native liver. However, the optimal strategy for long-term management of such patients remains unclear. Aiming to establish the current management strategies, we reviewed previous reports of long-term outcome of BA who underwent surgery at our institution as well as the relevant literature, focusing particularly on the treatment of late complications. Approximately 30-40% of long-term survivors of biliary atresia who retain their native liver exhibit late sequelae such as cholangitis and portal hypertension. Early and appropriate intervention with Kasai portoenterostomy is essential for ensuring long-term survival with good quality of life. In our hospital, the current standard for Kasai portoenterostomy involves dissecting the fibrous remnants along the porta hepatis, just on the level of the liver capsule. Cholangitis is an important late complication in biliary atresia, and the possibility of mechanical obstruction of the biliary drainage route or deformity of the intrahepatic bile ducts with or without gallstones should be thoroughly evaluated in patients with intractable cholangitis. Regarding portal hypertension, appropriate interventions such as endoscopic variceal treatment and partial splenic embolization are considered to provide good quality of life when hepatic function is preserved. Appropriate therapeutic management is strongly recommended in selected patients with late complications.

Glass fronted gas fireplaces (GFGFs) have exterior surfaces that can reach extremely high temperatures. Burn injuries from contact with the glass front can be severe with long-term sequelae. The Consumer Product Safety Commission reported that these injuries are uncommon, whereas single-center studies indicate a much higher frequency. The purpose of this multi-institutional study was to determine the magnitude and severity of GFGF injuries in North America. Seventeen burn centers elected to participate in this retrospective chart review. Chart review identified 402 children ≤10 years of age who sustained contact burns from contact with GFGF, who were seen or admitted to the study hospitals from January 2006 to December 2010. Demographic, burn, treatment, and financial data were collected. The mean age of the study group was 16.8 ± 13.3 months. The majority suffered burns to their hands (396, 98.5%), with burns to the face being the second, much less common site (14, 3.5%). Two hundred and sixty-nine required rehabilitation therapy (66.9%). The number of GFGF injuries reported was 20 times greater than the approximately 30 injuries estimated by the Consumer Product Safety Commission's 10-year review. For the affected children, these injuries are painful, often costly and occasionally can lead to long-term sequelae. Given that less than a quarter of burn centers contributed data, the injury numbers reported herein support a need for broader safety guidelines for gas fireplaces in order to have a significant impact on future injuries.

The purpose of this study was to review all cases of patients submitted to Westin's tenodesis, who had calcaneus feet secondary to myelomeningocele sequel, in order to evaluate the anatomical change provided by surgery and also to verify, in a long-term follow-up, the inversion of the deformity depending on the patient's age. In this longitudinal retrospective study, all medical records of patients with myelomeningocele sequelae submitted to Westin's tenodesis from 1993 to 2013 in a public university hospital were reviewed. Patients were contacted for new clinical and radiographic evaluations after a minimum of 36 months after surgery. The calcaneotibial angle was measured and the shortening of the fibula was calculated as the "intermalleolar height". The study was based on 16 children (26 feet), aged 84.27 months on average at the time of tenodesis. The calcaneotibial angle increased significantly post-operatively, from 63.77 degrees on average to 70.54 degrees. Intermalleolar height and valgus ankle did not change significantly. Most patients had plantigrade feet after surgery, without pressure ulcers, and were able to use orthoses. Westin's tenodesis, with or without other associated procedures, can correct or improve the calcaneus and valgus ankle deformity in patients with myelomeningocele sequelae. There was no association of the surgical result with age at the time of surgery. There was no inversion of the deformity in equinus during the follow-up time.

Acute kidney injury associated with endurance events—is it a cause for concern? A systematic review

Introduction A growing body of evidence suggests even small rises in serum creatinine (SCr) are of considerable clinical relevance. Given that participants in endurance events are exposed to potential (repeated) renal insults, a systematic review was undertaken to collate current evidence for acute kidney injury (AKI), complicating such events. Methods A systematic review of studies and case reports meeting inclusion criteria on Medline and EMBASE (inception to October 2015). Included: studies with markers of renal function before and after endurance or ultraendurance events; case reports of severe AKI. Two reviewers assessed risk of bias using the Newcastle-Ottawa scale. Results Eleven case report publications (n=27 individuals) of severe AKI, were retrieved, with risk factors including systemic illness or nephrotoxic medications usually identified. From 30 studies of endurance and ultraendurance events, mean rise in SCr was 29 (±12.3) µmol/L after marathon or ultramarathon (17 studies, n=568 participants) events. Where follow-up tests were conducted, SCr returned to baseline within 48 hours. Rises in biomarkers suggest potential parenchymal insult, rather than simply muscle breakdown. However, evidence of long-term deleterious effects is lacking. Conclusions Raised levels of SCr are reported immediately after endurance events. It is not clear whether this is either clinically significant, or if repeated participation predisposes to long-term sequelae. The aetiology of severe exercise-associated AKI is usually multifactorial, with risk factors generally identified in the rare cases reported. On-site biochemistry, urine analysis and biomarkers of AKI may help identify collapsed runners who are at significant short-term risk and allow suitable follow-up. PMID:29259804

Transesophageal echocardiography (TEE) in atrial fibrillation.

PubMed

Thamilarasan, M; Klein, A L

2000-11-01

Transesophageal echocardiography has given new insight into the pathogenesis of the thromboembolic sequelae of AF and expanded the available therapeutic options. Studies to date indicate that TEE-guided cardioversion is a safe and reasonable approach when the clinical situation warrants prompt restoration of sinus rhythm. Whether widespread use of this strategy offers further benefit remains to be established, although there are theoretical advantages to such an approach. The potential for earlier cardioversion using a TEE-guided approach may facilitate the achievement and maintenance of sinus rhythm. In the long term, earlier restoration of sinus rhythm prevents adverse atrial remodeling, lowers embolic risk, and may improve cardiac performance and functional status. Thromboembolic sequelae (either cardioversion-related or as a result of chronic AF) remain the most devastating complications of AF. Every attempt to minimize this risk should be pursued aggressively. Information gathered from TEE has helped to elucidate the mechanisms responsible for postcardioversion embolism and has emphasized the importance of anticoagulation during and after the restoration of sinus rhythm. TEE also has the potential to further risk stratify patients with AF. Ultimately, a subset of patients may be identified who require more intense anticoagulation (i.e., those with dense SEC or thrombus, or persistent thrombus after prolonged anticoagulation) or in whom cardioversion may be deferred entirely. Likewise, TEE also may prove to be useful in identifying patients with a low-clinical risk profile who may be treated with aspirin alone and patients in whom warfarin may be superior. The results of the ACUTE study should help to further define the role of TEE in the management of patients with AF. Additional clinical studies are needed to address some of the issues that have been raised and to allow for optimal use of TEE in this patient population.

The aim of this study was to assess the effectiveness of reverse total shoulder arthroplasty (RTSA) with an all-polyethylene glenosphere in patients with failed hemiarthroplasty (HH) or the sequelae of proximal humeral fractures. Thirty-six patients were assessed at a mean follow-up of 36 months using clinical scores and recording shoulder range of movement (ROM). Active anterior elevation (p < 0.001), lateral elevation (p < 0.001) and internal rotation (p < 0.0001) improved significantly, whereas improvement in external rotation was not significant. The mean Constant score rose significantly from 8.5 ± 7.6 to 40.7 ± 15.7 (p < 0.001) and the Simple Shoulder Test score from 0.42 ± 0.85 to 5.5 ± 2.6 (p < 0.001). Pain improved significantly from 8.7 ± 0.9 to 2.3 ± 1.2 (p < 0.001). Implant radiographic survivorship was 84.6 %. Scapular notching was detected in 7/36 patients (17.5 %). There were five complications: one (stiffness) among patients with fracture sequelae and four among those with failed HH (instability, n = 2; humeral component disassembly, n = 1; pain, n = 1). The two groups did not exhibit significant differences in pain, clinical scores or ROM. RTSA with an all-polyethylene glenosphere may have the potential to reduce the risk of biological notching due to polyethylene osteolysis. Further long-term studies are required to assess its efficacy. The good clinical performance and reasonable rate of notching of the polyethylene glenosphere support its use in primary and revision shoulder arthroplasty.

Vaginal breech delivery: results of a prospective registration study

PubMed Central

2013-01-01

Background Most countries recommend planned cesarean section in breech deliveries, which is considered safer than vaginal delivery. As one of few countries in the western world Norway has continued to practice planned vaginal delivery in selected women. The aim of this study is to evaluate prospectively registered neonatal and maternal outcomes in term singleton breech deliveries in a Norwegian hospital during a ten years period. We aim to compare maternal and neonatal outcomes in term breech pregnancies subjected either to planned vaginal or elective cesarean section. Methods A prospective registration study including 568 women with term breech deliveries (>37 weeks) consecutively registered at Sorlandet Hospital Kristiansand between 2001 and 2011. Fetal and maternal outcomes were compared according to delivery method; planned vaginal delivery versus planned cesarean section. Results Of 568 women, elective cesarean section was planned in 279 (49%) cases and vaginal delivery was planned in 289 (51%) cases. Acute cesarean section was performed in 104 of the planned vaginal deliveries (36.3%). There were no neonatal deaths. Two cases of serious neonatal morbidity were reported in the planned vaginal group. One infant had seizures, brachial plexus injury, and cephalhematoma. The other infant had 5-minutes Apgar < 4. Twenty-nine in the planned vaginal group (10.0%) and eight in the planned cesarean section group (2.9%) (p < 0.001) were transferred to the neonatal intensive care unit. However, only one infant was admitted for ≥4 days. According to follow-up data (median six years) none of these infants had long-term sequelae. Regarding maternal morbidity, blood loss was the only variable that was significantly higher in the planned cesarean section group versus in the vaginal delivery group (p < 0.001). Conclusions Strict guidelines were followed in all cases. There were no neonatal deaths. Two infants had serious neonatal morbidity in the planned vaginal group without long-term sequelae.

Accidental overdose in the deep shade of night: a warning on the assumed safety of 'natural substances'.

There is an increasing use of herbal remedies and medicines, with a commonly held belief that natural substances are safe. We present the case of a 50-year-old woman who was a trained herbalist and had purchased an 'Atropa belladonna (deadly nightshade) preparation'. Attempting to combat her insomnia, late one evening she deliberately ingested a small portion of this, approximately 50 mL. Unintentionally, this was equivalent to a very large (15 mg) dose of atropine and she presented in an acute anticholinergic syndrome (confused, tachycardic and hypertensive) to our accident and emergency department. She received supportive management in our intensive treatment unit including mechanical ventilation. Fortunately, there were no long-term sequelae from this episode. However, this dramatic clinical presentation does highlight the potential dangers posed by herbal remedies. Furthermore, this case provides clinicians with an important insight into potentially dangerous products available legally within the UK. To help clinicians' understanding of this our discussion explains the manufacture and 'dosing' of the A. belladonna preparation. 2015 BMJ Publishing Group Ltd.

Victimization and depressive distress symptoms represent serious and interconnected public health problems facing transgender communities. Avoidant coping is hypothesized to temporarily alleviate the stress of victimization, but has potential long-term mental and behavioral health costs, such as increasing the probability of depressive symptoms. A community sample of 412 transgender adults (M age = 32.7, SD = 12.8) completed a one-time survey capturing multiple forms of victimization (i.e., everyday discrimination, bullying, physical assault by family, verbal harassment by family, childhood sexual abuse, intimate partner violence), avoidant coping, and past-week depressive symptomology. Structural equation modeling examined the mediating role of avoidant coping in the association between victimization and depressive symptomology. A latent victimization variable composed of six measures of victimization was positively associated with avoidant coping, which in turn was positively associated with depressive symptoms. Victimization was also positively associated with depressive symptomology both directly and indirectly through avoidant coping. Avoidant coping represents a potentially useful intervention target for clinicians aiming to reduce the mental health sequelae of victimization in this highly stigmatized and vulnerable population.

Feminizing genitoplasties: Where are we now?

PubMed

Jesus, Lisieux Eyer

2018-04-26

Feminizing genitoplasties (FG) are controversial, because of possible adverse effects on sex life. Some have suggested limiting surgery to children presenting health problems related to their genital abnormality and patients who may give their informed consent. This paper analyzes research data about late results of FG, to substantiate the choice of whether to operate on children or to limit surgery to adults/adolescents. Review and synthesis of the literature about late results of FG. Eleven papers were found, involving different primary diseases and techniques (levels of evidence 3-4). There are no long-term data about corporeal sparing clitoroplasty, ASTRA procedures, and urogenital sinus mobilization. Surgery alters objective genital sensitivity, but most patients attest good subjective post-operative clitoral sensation. Complaints of poor clitoral sensation were related to reoperations, amputation, recession, atrophy, or neurovascular bundle injuries. CAH homozygous (null) genotypes show worse sensitivity and sex life, independent of surgery. Sexual function and avoidance are comparable between post-operated and virgin CAH patients. Problems with global auto-image were related to sexual difficulties. Introitus stenosis is frequent. Patients rarely reported distress concerning FG but vaginal self-dilatation is traumatic. Most patients operated on as young children evaluated timing of their surgery as correct. Biological, technical, and subjective factors influence females' attitudes towards sexual satisfaction. FG patients tend to be sexually insecure. Some sequelae described in adult women should be uncommon in contemporaneous cohorts, because of new techniques. Evidence about long-term sequelae of FG are of low quality and methodologically limited by unphysiological sensitivity measurement methods that do not correspond to subjective reports of the patients. Modern techniques have not been evaluated in the long term. The consequences of intentionally raising severely virilized children as females in our contemporaneous society have not been studied: such a decision still represents a social experiment.

Abstract The aim of this study was to investigate the survival and long-term morbidities of nasopharyngeal carcinoma (NPC) in children and adolescents. We retrospectively reviewed children and adolescents with NPC treated at Sun Yat-sen University Cancer Center from February 1991 to October 2010, where the prognostic factors and long-term effects of therapy were analyzed. A total of 148 patients were identified. The median age was 15 years old (range, 5–18 years) and the male to female ratio was 3.6:1. Most of the tumor histopathology was undifferentiated nonkeratinizing carcinoma (97.3%). The number of patients staged with IVa, IVb, IVc, III, and II were 45 (30.4%), 12 (8.1%), 5 (3.4%), 70 (47.3%), and 16 (10.8%), respectively. For the whole series with a median follow-up of 81 months (range, 6–282 months), the 5-year overall survival (OS) and disease-free survival (DFS) ratios were 79.3% and 69.7%, respectively. We observed significant differences in the 5-year OS (81.1% vs 25.0%, P = 0.002) and the DFS rates (72.2% vs 0.0%, P = 0.000) between patients with stage II to IVb disease and stage IVc disease. For patients with stage II, III, IVa, and IVb disease, we found a high radiation dose (dose > 66 Gy to the primary lesion) would not significantly improve the survival compared to the sub-high radiation dose group (dose = 60–66 Gy to the primary lesion), even considering the type of radiation therapy technologies. However, the incidences of sequelae (grades I–IV) in patients with high radiation dose were apparently higher than those in patients with low radiation dose. Considering the late sequelae, a dose of 60 to 66 Gy to the primary lesions seems to be enough for children and adolescents with NPC. PMID:27124036

Introduction Sexual dysfunction is a treatment sequela in rectal cancer (RC) survivors. Differences in health-related quality of life (HRQOL) may occur based on ostomy status (permanent ostomy versus anastomosis). Aim To describe alterations in sexual function and HRQOL based on ostomy status in long-term (≥ 5 years) RC survivors. Methods RC survivors with an ostomy (N=181) or anastomosis (N=394) were surveyed using validated HRQOL and functional status tools. We compared sexuality outcomes between the ostomy and anastomosis group, and reported differences adjusted for clinical and demographic characteristics. Qualitative data from one open-ended question on survivors’ greatest challenges since their surgery were analyzed to explore sexuality, symptoms, and relationships. Main Outcome Measures Whether sexually active, satisfaction with sexual activity, and select sexual dysfunction items from the Modified City of Hope Quality of Life-Ostomy (mCOH-QOL-O). Results Survivors with a permanent ostomy were more likely to have been sexually inactive after surgery if it occurred before year 2000, and experience dissatisfaction with appearance, interference with personal relationships and intimacy, and lower overall HRQOL. Female RC survivors with an ostomy were more likely to have problems with vaginal strictures and vaginal pain after surgery that persisted at the time of survey (5+ years later). Radiation treatment, tumor stage, soilage of garments in bed, and higher Charlson-Deyo co-morbidity scores were negatively associated with outcomes. Six qualitative themes emerged: loss of and decreased sexual activity; psychological issues with sexual activity, physical issues with sexual activity; partner rejection; ostomy interference with sexual activity; and positive experiences with sexuality. Conclusions Sexual dysfunction is a common long-term sequela of RC treatment, with more problems observed in survivors with a permanent ostomy. This warrants widespread implementation of targeted interventions to manage sexual dysfunction and improve HRQOL for these survivors. PMID:27318020

Birth asphyxia: pathophysiologic events and fetal adaptive changes.

PubMed

Woods, J R

1983-06-01

We have made significant advances toward understanding birth asphyxia and its effects upon neurologic development in the newborn and infant. The fetus is well adapted to compensate for moderate alterations in oxygen delivery. However, near lethal hypoxemia, prolonged exposure, and survival result in cell death and permanent neurologic sequelae. Neuroelectrical measurements such as the EEG and visual evoked potential provide insight into the acute alterations in nerve transmission during asphyxia, and in the recovery phase may ultimately provide information for long-term prognosis. These measurements are limited, however, by their inability once lost to distinguish cell inactivity from cell death. Permanent neurologic damage from asphyxia appears now to be a complex process in which severe hypoxemia precipitates a cascade of events leading to glycolysis, glycogenolysis, hypotension, and ultimately the accumulation of high concentrations of lactate at the cell level. As a consequence, cellular and extracellular fluid shifts produce cerebral edema, further impairment of cerebral circulation, and ultimately cell death. Clinical studies have helped to identify the newborn at high risk for neurologic impairment, but a cause-effect relationship remains unclear. That birth asphyxia can produce severe neurologic damage and death is generally accepted. Moreover, improper resuscitation of a severely depressed newborn increases the chance of permanent sequelae. The important clinical question is: Can one alter the natural course of asphyxia as has been alluded to through pharmacologic and ventilator manipulation? Answers to this question will depend upon continued study of the mechanisms of asphyctic damage in the central nervous system.

"Electrical shock is the physiological reaction or injury caused by electric current passing through the human body. It occurs upon contact of a human body part with any source of electricity that causes a sufficient current through the skin, muscles, or hair causing undesirable effects ranging from simple burns to death." Ventricular fibrillation is believed to be the most common cause of death after electrical shock. "The ideal duration of cardiac resuscitation is unknown. Typically prolonged cardiopulmonary resuscitation is associated with poor neurologic outcomes and reduced long term survival. No consensus statement has been made and traditionally efforts are usually terminated after 15-30 minutes." The case under discussion seems worthy of the somewhat detailed description given. It is for a young man who survived after 65 minutes after electrical shock (ES) after prolonged high-quality cardiopulmonary resuscitation (CPR), multiple defibrillations, and artificial ventilation without any sequelae. Early start of adequate chest compressions and close adherence to advanced cardiac life support protocols played a vital role in successful CPR.

Effects of psychological and biomechanical trauma on brain and behavior

McAllister, Thomas W.; Stein, Murray B.

2011-01-01

The current conflicts in Iraq and Afghanistan have resulted in a large cohort of military personnel exposed to combat-related psychological trauma as well as biomechanical trauma, including proximity to blast events. Historically, the long-term effects of both types of trauma have been viewed as having different neural substrates, with some controversy over the proper attribution of such symptoms evident after each of the major conflicts of the last century. Recently, great effort has been directed toward distinguishing which neuropsychiatric sequelae are due to which type of trauma. Of interest, however, is that the chronic effects of exposure to either process are associated with a significant overlap in clinical symptoms. Furthermore, similar brain regions are vulnerable to the effects of either psychological or biomechanical trauma, raising the possibility that shared mechanisms may underlie the clinically observed overlap in symptom profile. This paper reviews the literature on the neural substrate of biomechanical and psychological injury and discusses the implications for evaluation and treatment of the neuropsychiatric sequelae of these processes.

The aim of this research was to determine the prevalence of sexual abuse in Spain and its long and short effects. A representative sample of Spanish society was studied (N = 1.821) through proportional stratified random sampling. Data were obtained by interview (Personal History of Sexual Abuse), carried out in the subjects home and by means of a Self Reporting Questionnaire (S.R.Q.), which the interviewer gave the subject to be returned by post. The results show a high prevalence of sexual abuse prior to age 17 (15% of males and 22% of females) with short-term effects (lack of trust, disgust, fear, hostility towards the aggressor, shame, anxiety, etc.) and in long-term a greater tendency towards mental health problems (F = 7.7; p < .01), as well as other problems throughout the life cycle (running away from home, school failure, sexual dissatisfaction, drug-taking, etc.). The high prevalence and the clear long and short effect make prevention programs and help for the victims advisable.

Breast Cancer Survivorship: A Comprehensive Review of Long-Term Medical Issues and Lifestyle Recommendations

Bodai, Balazs I; Tuso, Phillip

2015-01-01

Long-term survival rates after a diagnosis of breast cancer are steadily rising. This is good news, but clinicians must also recognize that this brings new challenges to the medical community. As breast cancer becomes a chronic condition rather than a life-threatening illness owing to advances in early diagnosis and more effective treatments, health care practitioners must recognize and manage the long-term sequelae of the constellation of therapeutic modalities. Survivors of breast cancer represent a unique and extremely complex group of patients; not only do they have the challenge of dealing with multiple long-term side effects of treatment protocols, but many are also forced to address the preexisting comorbidities of their therapies, which often include multiple other issues. Therapies have additional and/or additive side effects that may interfere with treatments directed toward the new primary diagnosis of breast cancer. Our mandate is to establish a smooth transition from patient with breast cancer to survivor of breast cancer while providing ongoing and future guidance. Certainly, the information and resources to accomplish this transition are readily available; however, they are scattered throughout the literature and therefore are not easily accessible or available to the primary care physician. It is imperative that the information available regarding survivorship issues be accessible in an organized and useful format. This article is a modest attempt to provide a comprehensive review of the long-term medical issues relevant to survivorship after the diagnosis and treatment of breast cancer. A predicted shortage of oncologists by 2020 is well-recognized. Therefore, the bulk of long-term care will become dependent on the primary care physician. This shift of care means that these physicians will need to be well educated in the long-term medical issues related to breast cancer treatment. PMID:25902343

The aim of this study was to report the prevalence and nature of long-term diseases and their consequences in children under the age of 16 in Denmark, and to identify the socio-demographic determinants of disease. Parents and stepparents participating in the Danish Health and Morbidity Survey, 2000, were interviewed at home about long-term diseases, including impairments and sequelae after injury and disease, in children under the age of 16 living at home. Answers were given for 7,670 children, and diseases were coded according to ICD-10 by two doctors. Logistic regression analysis was used to identify the determinants and consequences of disease. A total of 16.2% of children had one or more long-term diseases, boys (17.5%) more frequently than girls (14.8%). The prevalence increased through the first six years of life. A social gradient was seen: children of parents with low socioeconomic status or with little education had a higher prevalence. The most frequent disease was asthma (4.9%). Also frequent were congenital disorders (1.6%), otitis media (1.4%) and hearing impairment (0.6%). Children with long-term disease suffered more frequently than others from poor health in general, recent sick leave and poor thriving. The figures for long-term disease reported by the parents participating in the study were in accordance with what was found in earlier studies, but stigmatising and less severe diseases, as well as periodically recurring diseases, were probably underreported. Attention should be paid to the high prevalence of asthma, to the poorer thriving and to the general health status of children with long-term disease, and to the social inequality in children's health.

Neuroparacoccidioidomycosis (NPCM) is a term used to describe the invasion of the central nervous system by the pathogenic fungus Paracoccidioides brasiliensis. NPCM has been described sporadically in some case reports and small case series, with little or no focus on treatment outcome and long-term follow-up. All patients with NPCM from January 1991 to December 2006 were analyzed and were followed until December 2009. Fourteen (3.8%) cases of NPCM were identified out of 367 patients with paracoccidioidomycosis (PCM). A combination of oral fluconazole and sulfamethoxazole/trimethoprim (SMZ/TMP) was the regimen of choice, with no documented death due to Paracoccidioides brasiliensis infection. Residual neurological deficits were observed in 8 patients. Residual calcification was a common finding in neuroimaging follow-up. All the patients in this study responded positively to the association of oral fluconazole and sulfamethoxazole/trimethoprim, a regimen that should be considered a treatment option in cases of NPCM. Neurological sequela was a relatively common finding. For proper management of these patients, anticonvulsant treatment and physical therapy support were also needed.

Diagnosis, prognosis, and clinical management of mild traumatic brain injury.

Levin, Harvey S; Diaz-Arrastia, Ramon R

2015-05-01

Concussion and mild traumatic brain injury (TBI) are interchangeable terms to describe a common disorder with substantial effects on public health. Advances in brain imaging, non-imaging biomarkers, and neuropathology during the past 15 years have required researchers, clinicians, and policy makers to revise their views about mild TBI as a fully reversible insult that can be repeated without consequences. These advances have led to guidelines on management of mild TBI in civilians, military personnel, and athletes, but their widespread dissemination to clinical management in emergency departments and community-based health care is still needed. The absence of unity on the definition of mild TBI, the scarcity of prospective data concerning the long-term effects of repeated mild TBI and subconcussive impacts, and the need to further develop evidence-based interventions to mitigate the long-term sequelae are areas for future research that will improve outcomes, reduce morbidity and costs, and alleviate delayed consequences that have only recently come to light.

Bell's palsy is unilateral, acute onset facial paralysis that is a common condition. One in every 65 people experiences Bell's palsy in the course of their lifetime. The majority of patients afflicted with this idiopathic disorder recover facial function. Initial treatment involves oral corticosteroids, possible antiviral drugs, and protection of the eye from desiccation. A small subset of patients may be left with incomplete recovery, synkinesis, facial contracture, or hemifacial spasm. A combination of medical and surgical treatment options exist to treat the long-term sequelae of Bell's palsy. Copyright © 2016 Elsevier Inc. All rights reserved.

Bell palsy (BP) is the most common diagnosis in acute and chronic facial palsy. Although most patients fully recover, more than one-quarter will have residual dysfunction. Of these, nearly half will demonstrate severe limitations in facial expression. Though significant attention has been paid to acute management and prognosis, a paucity of literature exists addressing management of the long-term sequelae of BP. This article describes contemporary use of physical therapy, injectables, and static and dynamic surgical procedures in facial reanimation of acute and chronic BP.

Occupational Therapy's Role in Cancer Survivorship as a Chronic Condition.

PubMed

Baxter, Mary Frances; Newman, Robin; Longpré, Sheila M; Polo, Katie M

Improved medical care has resulted in a documented increase in cancer survivors in the United States. Cancer survivors face challenges in participation across all facets of life as a result of the cancer and subsequent cancer treatments. Long-term and late-term sequelae can result in impairments in neurological systems, decreased stamina, loss of range of motion, and changes in sensation and cognition. These impairments are often long lasting, which categorizes cancer survivorship as a chronic condition. This categorization presents treatment challenges, especially in creating rehabilitation and habilitation service options that support cancer survivors. Occupational therapy provides a unique focus that can benefit cancer survivors as they face limitations in participation in all aspects of daily living. Research, advocacy, and education efforts are needed to focus on the specific rehabilitation and habilitation needs of cancer survivors to increase access to occupational therapy's distinct value.

To measure physical and neurologic impact of Haemophilus influenzae type b (Hib) meningitis on surviving children through short- and long-term follow-up. Cases of Hib meningitis, diagnosed at a tertiary level pediatric hospital, were subjected to short- and long-term follow-up and compared with age, sex, and area of residence matched healthy controls. Follow-up assessments included thorough physical and neurodevelopmental assessments using a standardized protocol by a multidisciplinary team. Assessments of short-term follow-up cohort (n = 64) revealed hearing, vision, mental, and psychomotor deficits in 7.8%, 3%, 20%, and 25% of the cases, respectively. Deficits were 10%, 1.4%, 21%, and 25% in long-term follow-up cohort (n = 71), in that order. Mental and psychomotor deficits were found in 2% of the controls, none of whom had vision or hearing deficits. In addition to risk of death, Hib meningitis in children causes severe disabilities in survivors. These data facilitated a comprehensive understanding of the burden of Hib meningitis, specifically in developing countries where disabled children remain incapacitated because of lack of resources and facilities. The evidence generated from this study is expected to provide a compelling argument in favor of introduction and continuation of Hib conjugate vaccine in the national immunization program for children.

Risk of thromboembolic complications in adult congenital heart disease: A literature review.

2018-05-30

Adult congenital heart disease (ACHD) is a constantly expanding population with challenging issues. Initial medical and surgical treatments are seldom curative, and the majority of patients still experience late sequelae and complications, especially thromboembolic events. These common and potentially life-threating adverse events are probably dramatically underdiagnosed. Better identification and understanding of thromboembolic risk factors are essential to prevent long-term related morbidities. In addition to specific situations associated with a high risk of thromboembolic events (Fontan circulation, cyanotic congenital heart disease), atrial arrhythmia has been recognized as an important risk factor for thromboembolic events in ACHD. Unlike in patients without ACHD, thromboembolic risk stratification scores, such as the CHA 2 DS 2 -VASc score, may not be applicable in ACHD. Overall, after a review of the scientific data published so far, it is clear that the complexity of the underlying congenital heart disease represents a major risk factor for thromboembolic events. As a consequence, prophylactic anticoagulation is indicated in patients with complex congenital heart disease and atrial arrhythmia, regardless of the other risk factors, as opposed to simple heart defects. The landscape of ACHD is an ongoing evolving process, and specific thromboembolic risk scores are needed, especially in the setting of simple heart defects; these should be coupled with specific trials or long-term follow-up of multicentre cohorts.

Single-suture craniosynostosis (SSC) is a common craniofacial condition with potential neurocognitive sequelae. To quantify any long-term functional academic and behavioural difficulties of children with SSC as indicated by the need for individualized education programs (IEPs), despite having undergone surgical treatment. Records of all school-age patients from 1992 to 2011 who underwent operative intervention for SSC were identified. Fifty-nine patients' guardians were contacted by telephone to provide informed consent for completion of a mailed standardized questionnaire querying demographic information as well as information regarding the patient's health, family and educational history; specifically whether the patient had ever been provided educational support as delineated in an IEP. The primary outcome measure was the history of the patient being assigned educational support as delineated in an IEP. Thirty-seven consenting guardians completed and returned the standardized questionnaire (response rate 62.7%). Twenty-one patients were male and 16 were female, with an age range of five to 14 years (mean age 10.2 years). Eleven (29.7%) patients had a previous history of or currently were receiving educational support delineated in an IEP. A higher proportion of school-age patients with a history of SSC (status postsurgical intervention) in the present study received educational support delineated in an IEP than the proportion of IEPs in the general student population of the United States (11.3%).

The Buffalo Cardio-metabolic Occupational Police Stress study, an occupational cohort study of police officers, was conducted to evaluate physiologic and stress measures in a high-risk occupation where occupational exposure to difficult criminal situations can lead to physiologic and psychological health consequences among those who enforce the law. The chronic exposure to human tragedy may place police officers at special risk for mental health disorders and the potential for misuse of alcohol or drugs. While exact etiologies of post-traumatic stress were not determined by this study, overall post-traumatic stress (PTS) prevalence rates among the police officers was 35%, with 10% of individuals demonstrating severe PTS symptomatology. Waking cortisol measures tended to be higher among officers with more PTS symptomatology, with some gender related differences noted. Given the increase in incarcerations for addictions related offenses over the past 20 years and the chronic exposure to human suffering and tragedy, early recognition of PTS symptoms is essential in making the diagnosis of post-traumatic stress in high-risk occupational cohorts. Providing early entry into treatment and subsequently attempting to eliminate or minimize long-term consequences of post-traumatic stress can have a significant impact on the prevention of long term sequelae of chronic stress, such as the use or misuse of drugs or alcohol.

Traumatic brain injury (TBI) is common in both military and civilian populations, and often results in neurobehavioral sequelae that impair quality of life in both patients and their families. Although individuals who are chronically exposed to stress are more likely to experience TBI, it is still unknown whether pre-injury stress influences the outcome after TBI. The present study tested whether behavioral and cognitive long-term outcome after TBI in rats is affected by prior exposure to an innate stress stimulus. Young adult male Sprague-Dawley rats were exposed to the predator odor 2,5-dihydro-2,4,5-trimethylthiazoline (TMT) or to water (WAT); exposure was repeated eight times at irregular intervals over a 2-week period. Rats were subsequently subjected to either mild-to-moderate bilateral brain injury (lateral fluid percussion [LFP]) or sham surgery (Sham). Four experimental groups were studied: Sham-WAT, Sham-TMT, LFP-WAT and LFP-TMT. Compared with Sham-WAT rats, LFP-WAT rats exhibited transient locomotor hyperactivity without signs of anxiety, minor spatial learning acquisition and hippocampal long-term potentiation deficits, and lower baseline activity of the hypothalamic-pituitary-adrenal axis with slightly stronger reactivity to restraint stress. Exposure to TMT had only negligible effects on Sham rats, whereas it exacerbated all deficits in LFP rats except for locomotor hyperactivity. Early brain inflammatory response (8 h post-trauma) was aggravated in rats pre-exposed to TMT, suggesting that increased brain inflammation may sustain functional deficits in these rats. Hence, these data suggest that pre-exposure to stressful conditions can aggravate long-term deficits induced by TBI, leading to severe stress response deficits, possibly due to dysregulated inflammatory response.

We present the results of the autopsy of a retired professional football player that revealed neuropathological changes consistent with long-term repetitive concussive brain injury. This case draws attention to the need for further studies in the cohort of retired National Football League players to elucidate the neuropathological sequelae of repeated mild traumatic brain injury in professional football. The patient's premortem medical history included symptoms of cognitive impairment, a mood disorder, and parkinsonian symptoms. There was no family history of Alzheimer's disease or any other head trauma outside football. A complete autopsy with a comprehensive neuropathological examination was performed on the retired National Football League player approximately 12 years after retirement. He died suddenly as a result of coronary atherosclerotic disease. Studies included determination of apolipoprotein E genotype. Autopsy confirmed the presence of coronary atherosclerotic disease with dilated cardiomyopathy. The brain demonstrated no cortical atrophy, cortical contusion, hemorrhage, or infarcts. The substantia nigra revealed mild pallor with mild dropout of pigmented neurons. There was mild neuronal dropout in the frontal, parietal, and temporal neocortex. Chronic traumatic encephalopathy was evident with many diffuse amyloid plaques as well as sparse neurofibrillary tangles and tau-positive neuritic threads in neocortical areas. There were no neurofibrillary tangles or neuropil threads in the hippocampus or entorhinal cortex. Lewy bodies were absent. The apolipoprotein E genotype was E3/E3. This case highlights potential long-term neurodegenerative outcomes in retired professional National Football League players subjected to repeated mild traumatic brain injury. The prevalence and pathoetiological mechanisms of these possible adverse long-term outcomes and their relation to duration of years of playing football have not been sufficiently studied. We recommend comprehensive clinical and forensic approaches to understand and further elucidate this emergent professional sport hazard.

The growing number of long-term cancer survivors poses a new challenge to health care systems. In Spain, follow-up is usually carried out in oncology services, but knowledge of cancer survivors' health care needs in this context is limited. The purpose of this study was to ascertain the health status of long-term survivors of breast, prostate, and colorectal cancer and to characterize their use of health care services. Retrospective multicenter cohort study. We collected data from patients' clinical histories and through telephone interviews, using a specially designed questionnaire that included the SF-36v2 Quality of Life and Nottingham Health Profile scales. The questionnaire was completed by 51.2% (n= 583) of the potential sample. No significant differences were observed between 5-year and 10-year survivors. Overall, more than 80% of respondents were undergoing drug treatment for morbidity related to advanced age. Quality of life was good in most patients, and cancer-related morbidity was low and of little complexity. For the most part, participants reported using primary care services for care of chronic diseases and opportunistic treatment of sequelae related to the cancer treatment. Oncological follow-up was centralized at the hospital. Survivors of breast, prostate and colorectal cancer with tumoral detection at an early stage and without recurrences or second neoplasms experienced little morbidity and enjoyed good quality of life. This study proposes exploration of a follow-up model in the Spanish health system in which primary care plays a more important role than is customary in cancer survivors in Spain.

There is limited information regarding the long-term outcome of inflicted traumatic brain injury (TBI), including shaken infant syndrome. The purpose of this study was to describe the long-term neurologic, behavioral, and cognitive sequelae seen in this population. A cross-sectional and prospective longitudinal study was conducted of 25 children with inflicted TBI in Scotland between 1980 and 1999. After consent was obtained, neurologic and cognitive examinations were performed on all participants and sequentially in the prospective cohort. Two global outcome measures were used: Glasgow Outcome Score (GOS) and Seshia's outcome score. Cognitive outcome was assessed using the Bayley Scales of Infant Development, British Ability Scales, and the Vineland Adaptive Behavior Scales. The mean length of follow-up was 59 months. A total of 68% of survivors were abnormal on follow-up, 36% had severe difficulties and were totally dependant, 16% had moderate difficulties, and 16% had mild difficulties on follow-up. A wide range of neurologic sequelae were seen, including motor deficits (60%), visual deficits (48%), epilepsy (20%), speech and language abnormalities (64%), and behavioral problems (52%). There was a wide range of cognitive abilities: the mean psychomotor index, 69.9 (SD: +/-25.73); and mean mental development index, 74.53 (SD: +/-28.55). Adaptive functioning showed a wide range of difficulties across all domains: communication domain (mean: 76.1; SD: +/-25.4), Daily living skills domain (mean: 76.9; SD: +/-24.3), and socialization domain (mean: 79.1; SD: +/-23.1). Outcome was found to correlate with the Pediatric Trauma Score and the Glasgow Coma Score but did not correlate with age at injury or mechanism of injury. Inflicted TBI has a very poor prognosis and correlates with severity of injury. Extended follow-up is necessary so as not to underestimate problems such as specific learning difficulties and attentional and memory problems that may become apparent only once the child is in school. Behavioral problems are present in 52% and begin to manifest clinically between the second and third years of life, although the consequences of frontal lobe injury may be underestimated unless follow-up is extended into adolescence and early adulthood.

Objective: To update the 1997 American Academy of Neurology (AAN) practice parameter regarding sports concussion, focusing on 4 questions: 1) What factors increase/decrease concussion risk? 2) What diagnostic tools identify those with concussion and those at increased risk for severe/prolonged early impairments, neurologic catastrophe, or chronic neurobehavioral impairment? 3) What clinical factors identify those at increased risk for severe/prolonged early postconcussion impairments, neurologic catastrophe, recurrent concussions, or chronic neurobehavioral impairment? 4) What interventions enhance recovery, reduce recurrent concussion risk, or diminish long-term sequelae? The complete guideline on which this summary is based is available as an online data supplement to this article. Methods: We systematically reviewed the literature from 1955 to June 2012 for pertinent evidence. We assessed evidence for quality and synthesized into conclusions using a modified Grading of Recommendations Assessment, Development and Evaluation process. We used a modified Delphi process to develop recommendations. Results: Specific risk factors can increase or decrease concussion risk. Diagnostic tools to help identify individuals with concussion include graded symptom checklists, the Standardized Assessment of Concussion, neuropsychological assessments, and the Balance Error Scoring System. Ongoing clinical symptoms, concussion history, and younger age identify those at risk for postconcussion impairments. Risk factors for recurrent concussion include history of multiple concussions, particularly within 10 days after initial concussion. Risk factors for chronic neurobehavioral impairment include concussion exposure and APOE ε4 genotype. Data are insufficient to show that any intervention enhances recovery or diminishes long-term sequelae postconcussion. Practice recommendations are presented for preparticipation counseling, management of suspected concussion, and management of diagnosed concussion. PMID:23508730

Streptococcus suis is a zoonotic cause of severe meningitis and sepsis in humans. We aimed to assess the long-term outcomes in patients who survived S. suis infection, in particular the progress and impact of vestibulocochlear sequelae. This case-control study evaluated outcomes of S. suis infection at discharge and 3 and 9 months post-discharge for 47 prospectively enrolled cases and at 11-34 months for 31 retrospectively enrolled cases. Outcomes in patients were compared to 270 controls matched for age, sex and residency. The prevalence ratio (PR) of moderate-to-complete hearing loss was 5.0(95%CI 3.6-7.1) in cases at discharge, 3.7(2.5-5.4) at 3 months, 3.2(2.2-4.7) at 9 months, and 3.1(2.1-4.4) in retrospective cases compared to controls. Hearing improvement occurred mostly within the first 3 months with a change in hearing level of 11.1%(95%CI 7.0-15.1%) compared to discharge. The PR of vestibular dysfunction was 2.4(95%CI 1.7-3.3) at discharge, 2.2(1.4-3.1) at 3 months, 1.8(1.1-2.5) at 9 months, and 1.8(1.1-2.6) for retrospective cases compared to controls. Cases also indicated more problems with mobility, self-care and usual activities. Both hearing and vestibular impairment were common and persist in cases. Appropriate patient management strategies are needed to reduce the incidence and impact of these sequelae. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

Enterovirus infections in childhood can be associated with significant neurological morbidity. This study aimed to describe the prevalence and range of neurological manifestations, determine the clinical characteristics and assess differences in clinical outcomes for Singaporean children diagnosed with enterovirus infections. In this single-centre, case-control study, clinical data was collected retrospectively from patients admitted to National University Hospital, Singapore, from August 2007 to October 2011 and diagnosed with enterovirus infection, based on the enterovirus polymerase chain reaction test, or cultures from throat and rectal swabs or cerebrospinal fluid samples. The occurrence of neurological manifestations was reviewed and clinical outcomes were assessed. A total of 48 patients (age range: six days-17.8 years) were included in the study. Neurological manifestations were seen in 75.0% of patients, 63.9% of whom presented with aseptic meningitis. Other neurological manifestations included encephalitis, acute cerebellitis, transverse myelitis and autonomic dysfunction. The incidence of neurological manifestations was significantly higher in patients aged > 1 year as compared to younger patients (p = 0.043). In patients without neurological manifestations, a significantly higher proportion presented with hand, foot and mouth disease and poor feeding. Long-term neurological sequelae were seen in 16.7% of patients with neurological manifestations. A wide spectrum of neurological manifestations resulting in a relatively low incidence of long-term neurological sequelae was observed in our study of Singaporean children with enterovirus infections. As some of these neurological morbidities were severe, careful evaluation of children with neurological involvement is therefore necessary. Copyright: © Singapore Medical Association

Toxicity and potential utility of ivermectin and moxidectin as xenointoxicants against the common bed bug, Cimex lectularius L.

The recent resurgence of the common bed bug Cimex lectularius L. throughout western industrialized nations has been facilitated in part by the insect becoming pesticide-resistant. Novel control strategies, including xenointoxication, should be considered to combat C. lectularius. Ivermectin, a U.S. Food and Drug Administration (FDA)-approved treatment for several human parasites, and the antiparasitic drug moxidectin, currently being explored in human clinical trials, were evaluated for efficacy against C. lectularius. Results showed that C. lectularius fed on ivermectin or moxidectin blood concentrations of >25 ng/mL and had significantly higher mortality (50-100 %) than controls (0-6 %) by day 13. Bed bugs that survived a blood meal containing >2.5 ng/mL of ivermectin suffered long-term sequelae including reduced fecundity, feeding difficulty, and incomplete ecdysis. Some insects that survived a blood meal containing ≤75 ng/mL moxidectin were able to feed and reproduce.

In this year's Advances in Asthma review, we discuss viral infections in asthmatic patients and potential therapeutic agents, the microbiome, novel genetic associations with asthma, air quality and climate effects on asthma, exposures during development and long-term sequelae of childhood asthma, patient-centered outcomes research, and precision medicine. In addition, we discuss application of biomarkers to precision medicine and new information on asthma medications. New evidence indicates that rhinovirus-triggered asthma exacerbations become more severe as the degree of sensitization to dust mite and mouse increase. The 2 biggest drivers of asthma severity are an allergy pathway starting with allergic sensitization and an environmental tobacco smoke pathway. In addition, allergic sensitization and blood eosinophils can be used to select medications for management of early asthma in young children. These current findings, among others covered in this review, represent significant steps toward addressing rapidly advancing areas of knowledge that have implications for asthma management.

How Well Do We Understand the Long-Term Health Implications of Childhood Bullying?

PubMed

Once dismissed as an innocuous experience of childhood, bullying is now recognized as having significant psychological effects, particularly with chronic exposure. Victims of bullying are at risk for a number of psychiatric disturbances, and growing evidence suggests that the pathophysiological effects of bullying, as with other forms of trauma and chronic stress, create additional health risks. We review the literature on the known sequelae of bullying, including psychiatric and physiological health effects, with a focus on implications for the victim. In addition, since it is now well established that early and chronic exposure to stress has a significant negative impact on health outcomes, we explore the implications of this research in relation to bullying and victimization in childhood. In particular, we examine how aspects of the stress response, via epigenetic, inflammatory, and metabolic mediators, have the capacity to compromise mental and physical health, and to increase the risk of disease. Research on the relevant mechanisms associated with bullying and on potential interventions to decrease morbidity is urgently needed.

Shoulder dystocia (SD) and brachial plexus palsy (BPP) are complications of childbirth that can result in significant long-term sequelae. The purpose of the present study was to analyze risk factors in cases of SD and BPP. We performed a retrospective study of laboring women who delivered a singleton, term, live-born infant at the Los Angeles County + University of Southern California Medical Center from 1995 to 2004. Multivariable logistic regression models were used to analyze risk factors among SD cases with and without BPP. Of the 13,998 deliveries that met inclusion criteria, 221 (1.6%) had SD. Of these, 42 (19.0%) had BPP. After testing for association with multiple potential risk factors, including maternal demographic variables, diabetes, hypertension, prior cesarean delivery, uterine abnormalities, induction of labor, prolonged second stage (adjusted by parity and epidural use), assisted vaginal delivery, and neonatal birth weight, no statistical association of BPP with any specific risk factor was identified. In the present study, we were unable to identify any reliable risk factors for BPP among deliveries with or without SD. SD and BPP remain unpredictable complications of childbirth.

2015-08-01

Nail-gun injury to the heart is rare. Nail-gun injury to the interventricular septum is rarer: we could find only 5 reported cases, and none involving a child. We report 2 additional cases, in which nails penetrated the interventricular septum without causing acute pericardial tamponade, heart block, or shunt across the septum. Transesophageal echocardiography provides a dynamic way to evaluate the patient preoperatively, intraoperatively, and postoperatively. In the cases reported here, both the adult with multiple interventricular nails and the child with a single nail underwent foreign-object removal via median sternotomy. The child needed cardiopulmonary bypass for removal of the nail. There were no short-term or long-term sequelae from these interventricular septal injuries.

2016-01-01

Perinatal hypoxic–ischemic brain injury results in neonatal hypoxic–ischemic encephalopathy and serious long-term neurodevelopmental sequelae. Magnetic resonance imaging (MRI) of the brain is an ideal and safe imaging modality for suspected hypoxic–ischemic injury. The pattern of injury depends on brain maturity at the time of insult, severity of hypotension, and duration of insult. Time of imaging after the insult influences the imaging findings. Mild to moderate hypoperfusion results in germinal matrix hemorrhages and periventricular leukomalacia in preterm neonates and parasagittal watershed territory infarcts in full-term neonates. Severe insult preferentially damages the deep gray matter in both term and preterm infants. However, associated frequent perirolandic injury is seen in term neonates. MRI is useful in establishing the clinical diagnosis, assessing the severity of injury, and thereby prognosticating the outcome. Familiarity with imaging spectrum and insight into factors affecting the injury will enlighten the radiologist to provide an appropriate diagnosis. PMID:27857456

Genitourinary Complications of Diabetes Mellitus: An Overview of Pathogenesis, Evaluation, and Management.

2017-01-01

Diabetes mellitus is a vastly prevalent metabolic disorder with escalating global health concerns. Particularly when mismanaged, chronic micro- and macrovascular complications may highly impair physiological systems while immunodeficiency disposes us to infection. We investigate infections, localized complications, and neoplasms of the genitourinary system secondary to the chronic complications of diabetes mellitus in males and females. A comprehensive MEDLINE® search was guided using key words relevant to diabetes mellitus and the genitourinary system. Pathogen-friendly environments may implicate the sequelae of urinary tract and genital mycotic infections, potentially generating necrosis, abscess, and other inflammatory complications, which may present concomitantly with neurogenic and/or vasculogenic dysfunction to further exacerbate an existing genitourinary condition. Manifestations of the adrenal, renal, and genital organs and tissues are discussed as they relate to vascular, immunodeficient, and other hyperglycemic complications of the diabetic state. Among those, chronic kidney disease and cystopathy are the most prevailing and detrimental. Though studies have connected diabetes to either an increased risk of developing or poor prognosis of bladder, renal, prostate, endometrial, and cervical cancers, the explicit biological relationships are as of yet inconclusive. Despite the availability of precise treatments to ameliorate most presently reviewed conditions, particularly urinary tract and genital mycotic infection-related sequelae, reversing permanent vascular damage remains a great challenge. Leading a healthier lifestyle and managing diabetes mellitus with a patient-centric approach from the outset are the most putative methods for preventing critical long-term genitourinary manifestations of diabetes mellitus.

The Community Preventive Services Task Force recommends combined diet and physical activity promotion programs for people at increased risk of type 2 diabetes, as evidence continues to show that intensive lifestyle interventions are effective for overweight individuals with prediabetes. To illustrate the potential clinical and economic benefits of treating prediabetes with lifestyle intervention to prevent or delay onset of type 2 diabetes and sequelae. This 2014 analysis used a Markov model to simulate disease onset, medical expenditures, economic outcomes, mortality, and quality of life for a nationally representative sample with prediabetes from the 2003-2010 National Health and Nutrition Examination Survey. Modeled scenarios used 10-year follow-up results from the lifestyle arm of the Diabetes Prevention Program and Outcomes Study versus simulated natural history of disease. Over 10 years, estimated average cumulative gross economic benefits of treating patients who met diabetes screening criteria recommended by the ADA ($26,800) or USPSTF ($24,700) exceeded average benefits from treating the entire prediabetes population ($17,800). Estimated cumulative, gross medical savings for these three populations averaged $10,400, $11,200, and $6,300, respectively. Published estimates suggest that opportunistic screening for prediabetes is inexpensive, and lifestyle intervention similar to the Diabetes Prevention Program can be achieved for ≤$2,300 over 10 years. Lifestyle intervention among people with prediabetes produces long-term societal benefits that exceed anticipated intervention costs, especially among prediabetes patients that meet the ADA and USPSTF screening guidelines.

Economic and societal pressures influence modern medical practice to develop and implement prevention strategies. Anterior cruciate ligament (ACL) injury devastates the knee joint leading to short term disability and long term sequelae. Due to the high risk of long term osteoarthritis in all treatment populations following ACL injury, prevention is the only effective intervention for this life-altering disruption in knee health. The “Sequence of Prevention” Model provides a framework to monitor progress towards the ultimate goal of preventing ACL injuries. Utilizing this model, our multidisciplinary collaborative research team has spent the last decade working to delineate injury mechanisms, identify injury risk factors, predict which athletes are at-risk for injury, and develop ACL injury prevention programs. Within this model of injury prevention, modifiable factors (biomechanical and neuromuscular) related to injury mechanisms likely provide the best opportunity for intervention strategies aimed to decrease the risk of ACL injury, particularly in female athletes. Knowledge advancements have led to the development of potential solutions that allow athletes to compete with lowered risk of ACL injury. Design and integration of personalized clinical assessment tools and targeted prevention strategies for athletes at high risk for ACL injury may transform current prevention practices and ultimately significantly reduce ACL injury incidence. This 2016 OREF Clinical Research Award focuses on the authors' work and contributions to the field. The author's acknowledge the many research groups who have contributed to the current state of knowledge in the fields of ACL injury mechanisms, injury risk screening and injury prevention strategies.

2014-02-01

Little is known regarding long-term performance decrements associated with mild Traumatic Brain Injury (mTBI). The goal of this study was to determine if individuals with an mTBI may be at increased risk for subsequent mishaps. Cox proportional hazards modeling was utilized to calculate hazard ratios for 518,958 active duty U.S. Air Force service members (Airmen) while controlling for varying lengths of follow-up and potentially confounding variables. Two non-mTBI comparison groups were used; the second being a subset of the original, both without head injuries two years prior to study entrance. Hazard ratios indicate that the causes of increased risk associated with mTBI do not resolve quickly. Additionally, outpatient mTBI injuries do not differ from other outpatient bodily injuries in terms of subsequent injury risk. These findings suggest that increased risk for subsequent mishaps are likely due to differences shared among individuals with any type of injury, including risk-taking behaviors, occupations, and differential participation in sports activities. Therefore, individuals who sustain an mTBI or injury have a long-term risk of additional mishaps. Differences shared among those who seek medical care for injuries may include risk-taking behaviors (Cherpitel, 1999; Turner & McClure, 2004; Turner, McClure, & Pirozzo, 2004), occupations, and differential participation in sports activities, among others. Individuals with an mTBI should be educated that they are at risk for subsequent injury. Historical data supported no lingering effects of mTBI, but more recent data suggest longer lasting effects. This study further adds that one of the longer term sequelae of mTBI may be an increased risk for subsequent mishap. Copyright © 2013 National Safety Council and Elsevier Ltd. All rights reserved.

Gorlin-Goltz syndrome is an autosomal dominant disorder principally characterized by cutaneous basal cell carcinomas, multiple keratocystic odontogenic tumors, and skeletal anomalies. This syndrome may be diagnosed early by dentist because keratocystic odontogenic tumors are usually one of the first manifestations of the syndrome. Early diagnosis and treatment are of utmost importance in reducing the severity of long term sequelae of this syndrome. This report presents a rare event of Gorlin-Goltz syndrome occurring in a 39-year-old male and his 8-year-old daughter. The clinical and investigative features of this familial disorder has been described in detail.

Early diagnosis and treatment are of utmost importance in reducing the severity of long term sequelae of this syndrome. This report presents a rare event of Gorlin-Goltz syndrome occurring in a 39-year-old male and his 8-year-old daughter. The clinical and investigative features of this familial disorder has been described in detail. PMID:22474649

Impairments in active and passive range of upper extremity supination and shoulder external rotation are common sequelae for children with delayed recovery from birth related brachial plexus injury. Orthotic intervention may complement traditional treatment strategies commonly employed in the newborn period. These authors describe their custom fabricated orthosis designed to balance shoulder growth and muscular function, and improve prognosis of long term functional outcomes for children with birth related brachial plexus injury. - Victoria Priganc, PhD, OTR, CHT, CLT, Practice Forum Editor.

Polycystic ovary syndrome (PCOS) is a good example of obesity-related cardiovascular complication affecting young women. PCOS is not only considered a reproductive problem but rather represents a complex endocrine, multifaceted syndrome with important health implications. Several evidences suggest an increased cardiovascular risk of cardiovascular disease associated with this syndrome, characterized by an impairment of heart structure and function, endothelial dysfunction and lipid abnormalities. All these features, probably linked to insulin-resistance, are often present in obese PCOS patients. Cardiovascular abnormalities represent important long-term sequelae of PCOS that need further investigations.

A 44-year-old man presented to hospital 24 h after an intentional overdose of metformin and gliclazide. He had a critical metabolic acidosis on presentation with a pH of 6.88, and very rapidly deteriorated into distributive shock refractory to large volume fluid resuscitation and massive doses of vasopressors. We introduced a methylene blue infusion as a rescue therapy in an attempt to improve the patient's haemodynamics, which was successful. The patient made a full recovery with no long-term sequelae.

2017-09-01

Lichen planus is an inflammatory mucocutaneous condition with a myriad of clinical manifestations. There are 3 forms of lichen planus that effect the vulva: papulosquamous, hypertrophic, and erosive. Erosive lichen planus can progress to vulvar scaring, vaginal stenosis, and squamous cell carcinoma; these long-term sequelae cause sexual distress, depression, and decreased quality of life for patients. Diagnosis is often delayed because of patient embarrassment or clinician misdiagnosis. Early recognition and treatment is essential to decreasing the morbidity of this condition. Multimodal treatment, along with a multidisciplinary approach, will improve outcomes and further clinical advances in studying this condition. Copyright © 2017 Elsevier Inc. All rights reserved.

1981-01-01

Chemical burns and pulmonary complications are the most common problems encountered in the patient immersed in gasoline. Our patient demonstrated a 46-percent total-body-surface area, partial-thickness chemical burn. Although he did not develop bronchitis or pneumonitis, he did display persistent atelectasis, laryngeal edema, and subsequent upper airway obstruction. This had not previously been reported in gasoline inhalation injuries. Hydrocarbon hepatitis secondary to the vascular endothelial damage is apparently a reversible lesion with no reported long-term sequelae. Gasoline immersion injuries may be a series multisystem injury and require the burn surgeon to take a multisystem approach to its diagnosis and treatment.

Echocardiography for patent ductus arteriosus including closure in adults.

2015-01-01

Patent ductus arteriosus (PDA) represents at least 5-10% of all congenital heart defects (CHDs) making it a very important commonly diagnosed lesion. Although spontaneous closure of the PDA occurs within 24 to 48 hours after birth in the majority, those children who do not have natural or surgical closure may have a persistent PDA into adulthood. The diagnosis is most often confirmed by echocardiography that also guides catheter-based interventions and surgeries. Echocardiography continues to be the most important tool in long-term follow-up of residua and sequelae. © 2014, Wiley Periodicals, Inc.

Since Tanzini, the latissimus dorsi muscle flap has been widely used in plastic surgery. Based on the experience of two plastic surgery units, we decided to try to define the sequelae of this operation. In order to simplify our analysis we only considered free flaps. Out study is based on 42 patients (26 pure muscular flaps and 16 musculo-cutaneous flaps). The sequelae were analysed in terms of aesthetic and functional criteria. The aesthetic sequelae appeared to be minima in the case of pure muscular flaps, but more severe in the case of musculo-cutaneous flaps. Functional sequelae in the shoulder were observed on muscle testing in 30% of cases, although there were no repercussions on sport or work activities. Analysis of spinal posture demonstrated a modification in the frontal plane in 40% of cases although this could not be clearly attributed to the donor site. On the basis of this study, we can conclude that the latissimus dorsi flap retains an important place in the therapeutic arsenal of plastic surgery due to its reliability and its minor cicatricial and functional sequelae at the donor site.

Metabolic Profiles in Ovine Carotid Arteries with Developmental Maturation and Long-Term Hypoxia

Goyal, Ravi; Longo, Lawrence D.

Background Long-term hypoxia (LTH) is an important stressor related to health and disease during development. At different time points from fetus to adult, we are exposed to hypoxic stress because of placental insufficiency, high-altitude residence, smoking, chronic anemia, pulmonary, and heart disorders, as well as cancers. Intrauterine hypoxia can lead to fetal growth restriction and long-term sequelae such as cognitive impairments, hypertension, cardiovascular disorders, diabetes, and schizophrenia. Similarly, prolonged hypoxic exposure during adult life can lead to acute mountain sickness, chronic fatigue, chronic headache, cognitive impairment, acute cerebral and/or pulmonary edema, and death. Aim LTH also can lead to alteration in metabolites such as fumarate, 2-oxoglutarate, malate, and lactate, which are linked to epigenetic regulation of gene expression. Importantly, during the intrauterine life, a fetus is under a relative hypoxic environment, as compared to newborn or adult. Thus, the changes in gene expression with development from fetus to newborn to adult may be as a consequence of underlying changes in the metabolic profile because of the hypoxic environment along with developmental maturation. To examine this possibility, we examined the metabolic profile in carotid arteries from near-term fetus, newborn, and adult sheep in both normoxic and long-term hypoxic acclimatized groups. Results Our results demonstrate that LTH differentially regulated glucose metabolism, mitochondrial metabolism, nicotinamide cofactor metabolism, oxidative stress and antioxidants, membrane lipid hydrolysis, and free fatty acid metabolism, each of which may play a role in genetic-epigenetic regulation.

Pavlovsky, S.; Fisman, N.; Arizaga, R.

Neurological, psychopedagogic, and psychologic long-term sequelae were evaluated in two groups of ALL patients in continuous CR for more than 2 years treated with two different CNS prophylaxis schemes. Group A, 19 patients received cranial irradiation 2400 rads plus IT MTX-DMT, and group B, 23 patients IT MTX-DMT only during induction and maintenance. All the patients were evaluated by performing neurological examination, EEG, EMG with nerve conduction velocity, CT scans, CSF studies, psychometric and psychologic studies, and neuropsychological evaluation. The most important findings were: 11 patients from group A (58%) showed abnormal CT and only one patient from group Bmore » showed CT abnormalities. The neuropsychologic evaluation (performed by L. Bender technique and Picq-Vayer scale) showed more severe impairment (grade 3-4) in eight patients from group A (42%) and none in group B (p less than 0.001). Higher incidence of abnormalities in group A suggests the existence of more severe sequelae in the patients treated with cranial irradiation plus IT MTX-DMT than with IT MTX-DMT alone.« less

Nerve conduction velocity in human limbs with late sequelae after local cold injury.

1996-06-01

Cold-induced neuropathy may play a dominant role in the long-term sequelae with cold sensitivity after local cold injuries (LCIs). Somatosensory functions were assessed and nerve conduction velocity (NCV) and motor distal delay (MDD) were measured in the limbs of 31 Norwegian former soldiers with persistent cold intolerance 3-4 years after the primary LCI. NCV measurements were performed in 24 lower and 16 upper extremities. NCV was related to degree of overall subjective complaints quantified by means of a visual analogue scale (VAS). Motor (MNCV) and sensory conduction velocity (SNCV) in the lower extremities and SNCV in the hands were significantly decreased compared with controls. MDD was pathologically increased in the feet. NCV of the forearms ranged from normal to significant reduction. The more pronounced effect on the lower extremities may be caused by deeper cooling of the calves compared with forearms for several reasons. No significant associations were found between VAS and NCV except for the right median nerve. NCV measurements may provide objective findings in cold-injured patients and in those with few or no conspicuous clinical signs.

Cytomegalovirus (CMV) is the most frequent cause of congenital infection, and both symptomatic and asymptomatic infants may have long term sequelae. Children with congenital CMV infection are chronically infected and excrete CMV in the urine for prolonged periods. However, the effect of prolonged viral replication on the long term outcome of these children is unknown. To determine whether duration of CMV excretion is associated with outcome at 6 years of life in symptomatic and asymptomatic congenitally infected children. Longitudinal cohort study. Children congenitally infected with CMV were identified at birth and followed prospectively in a study of long term effects of congenital CMV infection. The relationship between duration of CMV urinary excretion and growth, neurodevelopment and presence and progression of sensorineural hearing loss (SNHL) at 6 years of age was determined. There was no significant difference in the duration of viral urinary excretion between children born with asymptomatic (median, 4.55 years) and symptomatic (median, 2.97 years) congenital CMV infection (P = 0.11). Furthermore there was no association between long term growth or cognitive outcome and duration of viral excretion. However, a significantly greater proportion of children who excreted CMV for <4 years had SNHL and progressive SNHL compared with children with CMV excretion >4 years (P = 0.019, P = 0.009, respectively). Children congenitally infected with CMV are chronically infected for years, but the duration of CMV urinary excretion is not associated with abnormalities of growth, or neurodevelopmental deficits. However, SNHL and progressive SNHL were associated with a shorter duration of CMV excretion.

Medulloblastoma is the most common malignant brain tumour in children and is treated with a combination of surgery, radiotherapy and chemotherapy. These children frequently experience long-term cognitive, social and physical sequelae, which significantly affect school reintegration. This study aimed to explore school-return experiences to create a more structured school reintegration protocol for children postmedulloblastoma. A cohort of nine patients who had completed treatment and for whom full neuropsychometric data were available was included in the study (median time since diagnosis 8 years). Data were collected using qualitative parental questionnaires, semistructured interviews with teachers (n = 12) and healthcare professionals (HCPs) (n = 6) involved in their school reintegration. Thematic analysis was employed. A focus group with five HCPs was then used for data validation. This study uncovered the following four main subjects: (1) Information sharing; (2) education and empowerment (of educational professionals (EP) and parents); (3) communication between parents, HCPs and EPs; and (4) long-term difficulties. Implementation of a standardised protocol delivered within the structure of a school passport document would aid uniform follow-up. The proposed multistage protocol includes early communication and reintegration planning followed by meetings at school re-entry. Follow-up meetings are suggested to reduce information loss and reassess the child's needs. Hospital support at school transitions, inclusion of school data in long-term clinical follow-up and long-term rehabilitation are also recommended. Each stage would be supported by school passport documentation and would facilitate school and parental empowerment, paramount to the long-term sustainability of successful schooling. © 2016 Wiley Periodicals, Inc.

Childhood malnutrition and the intestinal microbiome.

2015-01-01

Malnutrition contributes to almost half of all deaths in children under the age of 5 y, particularly those who live in resource-constrained areas. Those who survive frequently suffer from long-term sequelae including growth failure and neurodevelopmental impairment. Malnutrition is part of a vicious cycle of impaired immunity, recurrent infections, and worsening malnutrition. Recently, alterations in the gut microbiome have also been strongly implicated in childhood malnutrition. It has been suggested that malnutrition may delay the normal development of the gut microbiota in early childhood or force it toward an altered composition that lacks the required functions for healthy growth and/or increases the risk for intestinal inflammation. This review addresses our current understanding of the beneficial contributions of gut microbiota to human nutrition (and conversely the potential role of changes in that community to malnutrition), the process of acquiring an intestinal microbiome, potential influences of malnutrition on the developing microbiota, and the evidence directly linking alterations in the intestinal microbiome to childhood malnutrition. We review recent studies on the association between alterations in the intestinal microbiome and early childhood malnutrition and discuss them in the context of implications for intervention or prevention of the devastation caused by malnutrition.

Proteus mirabilis and its role in dacryocystitis.

PubMed

Borgman, Christopher J

2014-09-01

Dacryocystitis is a common inflammation of the lacrimal sac, usually from an underlying bacterial infection. Most cases can be attributed to common ocular flora such as Staphylococcus aureus or Streptococcus pneumoniae; however, uncommon bacterial causes such as Proteus mirabilis can still occur. P. mirabilis is a gram-negative bacillus that is found abundantly in people who have undergone long-term catheterization and is uncommonly found in or around the eyes except in people who have undergone long-term catheterization. Proteus species can cause conjunctivitis, canaliculitis, and dacryocystitis and have the ability to manifest into preseptal cellulitis; therefore, timely recognition and treatment are important to prevent potential further complications. An 84-year-old white man had several recurrences of acute dacryocystitis that had marginal improvement with empiric antibiotic treatment. Resultant culture of the ocular discharge revealed an uncommon bacterium, P. mirabilis. Successful dosing of oral antibiotics resolved the infection but ultimately the patient required an external dacryocystorhinostomy (DCR) procedure to maintain patency of the nasolacrimal lacrimal system and prevent recurrence. At 3 months after external DCR, the patient was symptom free with no recurrences. Dacryocystitis has a distinctive clinical presentation and is usually easily treated when appropriate oral antibiotics are directed at the underlying pathogen. In nonresponsive cases, culturing of the ocular discharge should be performed to identify the underlying pathogen. Cases of dacryocystitis caused by Proteus species are usually responsive to several standard antibiotics used orally in eye care; however, culturing and susceptibility testing can streamline the diagnostic and management sequence considerably in unclear or unresponsive cases. Typically, patients with dacryocystitis return to normal after appropriate treatment, but chronic recurrences and epiphora are potential sequelae. Patients should be educated that a DCR surgical procedure may be needed to prevent future recurrences in some cases.

The aim of this study was to investigate psychological stress in parents of children with esophageal atresia and to explore factors associated with the development of Posttraumatic Stress disorder (PTSD). Self-report questionnaires were administered to parents of children with EA. Domains included: (1) sociodemographic data, current personal difficulties, assessment scales for the quality of life and for the global health status of the child (2) French-validated versions of the Perinatal Posttraumatic Stress disorder Questionnaire and of the State-Trait Anxiety Inventory. Associations between PTSD and severity of the neonatal course, presence of severe sequelae at 2 years of age, and quality of life and global health status of children according to their parents' perception were studied. A Tertiary care University Hospital. Among 64 eligible families, 54 parents of 38 children (59%) participated to the study. PTSD was present in 32 (59%) parents; mothers were more frequently affected than fathers (69 vs 46%, p = 0.03). Four mothers (8%) had severe anxiety. PTSD was neither associated with neonatal severity nor with severe sequelae at 2 years. Parents with PTSD rated their child's quality of life and global health status significantly lower (7.5 vs 8.6; p = 0.01 and 7.4 vs 8.3; p = 0.02 respectively). PTSD is frequent in parents of children with esophageal atresia, independently of neonatal severity and presence of severe sequelae at 2 years of age. Our results highlight the need for a long-term psychological support of families.

Purpose: Pediatric intramedullary spinal cord tumors are exceedingly rare; in the United States, 100 to 200 cases are recognized annually, of these, most are astrocytomas. The purpose of this study is to report the outcomes in pediatric patients with spinal cord astrocytomas treated at a tertiary care center. Methods and Materials: An institutional review board-approved retrospective single-institution study was performed for pediatric patients with spinal cord astrocytomas treated at our hospital from 1990 to 2010. The patients were evaluated on the extent of resection, progression-free survival (PFS), and development of radiation-related toxicities. Kaplan-Meier curves and multivariate regression model methods weremore » used for analysis. Results: Twenty-nine patients were included in the study, 24 with grade 1 or 2 (low-grade) tumors and 5 with grade 3 or 4 (high-grade) tumors. The median follow-up time was 55 months (range, 1-215 months) for patients with low-grade tumors and 17 months (range, 10-52 months) for those with high-grade tumors. Thirteen patients in the cohort received chemotherapy. All patients underwent at least 1 surgical resection. Twelve patients received radiation therapy to a median radiation dose of 47.5 Gy (range, 28.6-54.0 Gy). Fifteen patients with low-grade tumors and 1 patient with a high-grade tumor exhibited stable disease at the last follow-up visit. Acute toxicities of radiation therapy were low grade, whereas long-term sequelae were infrequent and manageable when they arose. All patients with low-grade tumors were alive at the last follow-up visit, compared with 1 patient with a high-grade tumor. Conclusion: Primary pediatric spinal cord astrocytomas vary widely in presentation and clinical course. Histopathologic grade remains a major prognostic factor. Patients with low-grade tumors tend to have excellent disease control and long-term survival compared to those with high-grade tumors. This experience suggests that radiation therapy may enhance tumor control with an acceptably low risk of long-term sequelae in this sensitive patient population.« less

BACKGROUND: Single-suture craniosynostosis (SSC) is a common craniofacial condition with potential neurocognitive sequelae. OBJECTIVE: To quantify any long-term functional academic and behavioural difficulties of children with SSC as indicated by the need for individualized education programs (IEPs), despite having undergone surgical treatment. METHODS: Records of all school-age patients from 1992 to 2011 who underwent operative intervention for SSC were identified. Fifty-nine patients’ guardians were contacted by telephone to provide informed consent for completion of a mailed standardized questionnaire querying demographic information as well as information regarding the patient’s health, family and educational history; specifically whether the patient had ever been provided educational support as delineated in an IEP. The primary outcome measure was the history of the patient being assigned educational support as delineated in an IEP. RESULTS: Thirty-seven consenting guardians completed and returned the standardized questionnaire (response rate 62.7%). Twenty-one patients were male and 16 were female, with an age range of five to 14 years (mean age 10.2 years). Eleven (29.7%) patients had a previous history of or currently were receiving educational support delineated in an IEP. CONCLUSIONS: A higher proportion of school-age patients with a history of SSC (status postsurgical intervention) in the present study received educational support delineated in an IEP than the proportion of IEPs in the general student population of the United States (11.3%).

Failed Retrieval of an Inferior Vena Cava Filter During Pregnancy Because of Filter Tilt: Report of Two Cases

DOE Office of Scientific and Technical Information (OSTI.GOV)

McConville, R. M., E-mail: richard_mcconville@hotmail.com; Kennedy, P. T.; Collins, A. J.

Thromboembolic disease during pregnancy is an important cause of obstetric morbidity and mortality. Pregnant patients with venous thromboembolism are usually managed by conventional anticoagulation. However, this must be discontinued during vaginal or caesarian delivery to avoid haemorrhage and to reduce the risk of possible epidural haematoma. Retrievable inferior vena cava filters (IVCFs) offer protection against pulmonary embolism during this high-risk period, when anticoagulation is discontinued, while avoiding potential long-term sequelae of a permanent IVCF. Here we report two patients who presented in the third trimester of pregnancy with floating ileofemoral deep vein thrombosis. Both patients were initially treated with standardmore » anticoagulation; however, shortly before delivery both patients had a retrievable IVCF placed in a suprarenal position. In both patients, retrieval failed at 28 days after insertion because of filter tilt. The timing and mechanism of filter tilt remains uncertain. We believe that a number of factors could have been involved, including change in the anatomic configuration with lateral displacement of the IVCF as a result of the gravid uterus as well as forceful uterine contractions during labour, which modified the shape and diameter of the IVC. We showed that failure to retrieve the IVCF has had considerable implications for the two young patients regarding long-term anticoagulation and have highlighted the need for further clinical trials regarding the safe use of retrievable IVCFs during pregnancy.« less

Infant Attachment Moderates Paths From Early Negativity to Preadolescent Outcomes for Children and Parents

Boldt, Lea J.; Kochanska, Grazyna; Jonas, Katherine

2016-01-01

Although infant attachment has been long seen as key for development, its long-term effects may be complex. Attachment may be a catalyst or moderator of future developmental sequelae rather than a source of main effects. In 102 mothers, fathers, and infants, attachment was assessed at 15 months, children’s negativity (rejection of parental rules and modeling attempts) at 25, 38, 52, and 67 months, and developmental outcomes (the child’s parent-rated externalizing problems and the parent-child observed relationship quality) at ages 10 and 12. In both mother- and father-child relationships, children’s higher negativity was associated with more detrimental outcomes, but only in dyads with formerly insecure infants. Infant insecurity appears to amplify detrimental cascades, whereas infant security appears to defuse such risks. PMID:27569427

Nasopharyngeal carcinoma (NPC) is very rare in childhood. It differs from its adult counterpart in the prevalence of the nonkeratinizing, undifferentiated subtype and by an advanced clinical stage at onset and better chances of survival. The risk of long-term treatment-related toxicity also may be a more important issue in younger individuals. A prospective chemoradiotherapy protocol for pediatric NPC was started in Italy in 2000 within the framework of the Rare Tumors in Pediatric Age (TREP) project. Three courses of cisplatin/5-fluorouracil induction chemotherapy were followed by radiotherapy (doses up to 65 grays) with concomitant cisplatin. Forty-six patients (ages 9-17 years) were considered eligible for the study over a 10-year period. The ratio of observed to expected cases based on epidemiological data was approximately 1 for both children and adolescents. All but 1 patient had lymph node involvement, and 5 patients had distant metastases. The rate of response to primary chemotherapy was 90%. The 5-year overall and progression-free survival rates were 80.9% and 79.3%, respectively (median follow-up, 62 months). The only statistically significant prognostic variable was the presence or absence of distant metastases. A 65% incidence of late sequelae was reported. This study demonstrates the feasibility and efficacy of a prospective protocol even for such rare tumors as pediatric NPC. The use of lower radiotherapy doses than those used in adults did not affect locoregional failure rates. Long-term follow-up will be needed to obtain more information on both survival and treatment sequelae. The next objective will be to establish broader, international prospective cooperation schemes.

To describe the pregnancy outcome, including long-term follow-up of the offspring, of pregnant women with cat scratch disease. A surveillance study performed over 19 years identified eight pregnant women with cat scratch disease. A case of cat scratch disease was defined as a patient with a history of cat contact with regional lymphadenitis, other manifestations, or a combination of these consistent with the disease and one or more confirmatory laboratory tests. The clinical and laboratory manifestations and pregnancy outcome of all women diagnosed with cat scratch disease during pregnancy are described. Five of the eight pregnant women had typical disease with regional lymphadenitis; two had regional lymphadenitis with arthralgia, myalgia, and erythema nodosum; and one had neuroretinitis. Delayed diagnosis was common, although all women had a history of recent cat exposure. One woman who presented with clinical cat scratch disease during the first month of pregnancy had a spontaneous abortion. Another elected to terminate the pregnancy because of concerns related to radiation associated with abdominal computed tomography scan performed as part of an evaluation for suspected malignancy. The other six women gave birth to healthy newborns without congenital anomalies. No sequelae were recorded in mothers or children during a median follow-up of 4.5 years (range 0.5-9.5 years). With the exception of one early spontaneous abortion in which causality to cat scratch disease could not be established, neither deleterious effects of cat scratch disease on newborns nor reports of long-term sequelae were found. Physicians, especially family physicians and obstetrician-gynecologists need to be more familiar with the clinical manifestations of cat scratch disease. Close monitoring of infected women during pregnancy is advisable until more data are available to determine the optimal diagnostic and therapeutic approach.

Proton magnetic resonance spectroscopy ((1)H-MRS) was recently used to examine altered metabolism in the white matter (WM) of patients experiencing carbon monoxide (CO) poisoning; however, only a small number of patients with delayed neurologic sequelae (DNS) were analyzed. We aimed to detect altered metabolism in the WM of patients with DNS using (1)H-MRS; to explore its clinical relevance in the management of patients experiencing CO poisoning. Patients experiencing acute CO poisoning underwent (1)H-MRS and cerebrospinal fluid (CSF) examination within 1week and at 1month after acute poisoning. Metabolites including choline-containing compounds (Cho), creatine (Cr), N-acetylaspartate (NAA), and lactate were measured from the periventricular WM. Myelin basic protein (MBP) concentrations were measured in CSF. Fifty-two patients experiencing acute CO poisoning (15 with DNS, 37 without DNS; median age, 49years; 65% males) underwent (1)H-MRS. Within 1week, NAA/Cr ratios, reflecting neuroaxonal viability, were lower in patients with DNS than in those without DNS (P<0.05). At 1month, when 9 of 15 patients (60%) developed DNS, Cho/Cr ratios were higher, and NAA/Cr and NAA/Cho ratios lower in patients with DNS (P=0.0001, <0.0001, and <0.0001, respectively), indicating increased membrane metabolism and decreased neuroaxonal viability. (1)H-MRS parameter abnormalities correlated with the elevation of MBP in CSF. The presence of a lactate peak was a predictor for a poor long-term outcome. (1)H-MRS within 1week may be useful for predicting DNS development; (1)H-MRS at 1month may be useful for discriminating patients with DNS and predicting long-term outcomes.

To update the 1997 American Academy of Neurology (AAN) practice parameter regarding sports concussion, focusing on 4 questions: 1) What factors increase/decrease concussion risk? 2) What diagnostic tools identify those with concussion and those at increased risk for severe/prolonged early impairments, neurologic catastrophe, or chronic neurobehavioral impairment? 3) What clinical factors identify those at increased risk for severe/prolonged early postconcussion impairments, neurologic catastrophe, recurrent concussions, or chronic neurobehavioral impairment? 4) What interventions enhance recovery, reduce recurrent concussion risk, or diminish long-term sequelae? The complete guideline on which this summary is based is available as an online data supplement to this article. We systematically reviewed the literature from 1955 to June 2012 for pertinent evidence. We assessed evidence for quality and synthesized into conclusions using a modified Grading of Recommendations Assessment, Development and Evaluation process. We used a modified Delphi process to develop recommendations. Specific risk factors can increase or decrease concussion risk. Diagnostic tools to help identify individuals with concussion include graded symptom checklists, the Standardized Assessment of Concussion, neuropsychological assessments, and the Balance Error Scoring System. Ongoing clinical symptoms, concussion history, and younger age identify those at risk for postconcussion impairments. Risk factors for recurrent concussion include history of multiple concussions, particularly within 10 days after initial concussion. Risk factors for chronic neurobehavioral impairment include concussion exposure and APOE ε4 genotype. Data are insufficient to show that any intervention enhances recovery or diminishes long-term sequelae postconcussion. Practice recommendations are presented for preparticipation counseling, management of suspected concussion, and management of diagnosed concussion.

Superficial ocular malignancies treated with strontium-90 brachytherapy: long term outcomes.

The incidence of conjunctival malignancies is less than 1%. Though surgical excision remains the mainstay of treatment, the incidence of positive surgical margins and local recurrence rates are high, which is approximately up to 33% in negative margins and 56% in positive margins. Radiotherapy reduces the risk of recurrence in these cases. Brachytherapy using β emitters such as strontium-90 ((90)Sr) is an ideal treatment technique for these tumors with the advantage of treating only a few millimeters of tissue while sparing the underlying normal eye. We report the long term outcomes in the form of local control and late sequelae of patients with conjunctival malignancies treated with (90)Sr applicator brachytherapy. During 1999-2013, 13 patients with conjunctival tumors, treated using (90)Sr brachytherapy were analyzed. Brachytherapy was either in a post-operative adjuvant or in a recurrent setting. Local control (LC), disease free survival (DFS), overall survival (OS), and late sequelae were evaluated. The median age at presentation was 47 years (range: 11-71 years). Thirteen patients with 15 tumors were treated. The commonest histology was squamous cell carcinoma. The median dose was 44 Gy over 11 fractions. The median follow up of all the patients was 51 months (range: 3-139 months). The median follow up of patients with carcinoma only was 64 months with a LC and DFS of 90.9% at 5 years. None of the patients developed ≥ grade II Radiation Therapy Oncology Group (RTOG) acute toxicities. One patient developed a focal scar and another developed corneal opacification at the limbus. Vision was not impaired in any of the patients. Strontium-90 brachytherapy used in early invasive conjunctival malignancies as an adjunct to surgery in primary and recurrent settings, results in optimal disease control and ocular functional outcomes.

Risk-adapted, long-term management in childhood-onset craniopharyngioma.

Müller, Hermann L

2017-04-01

This report is a review of findings on the diagnosis, treatment, clinical course, follow-up, and prognosis of craniopharyngioma patients with special regard to clinical trials and long-term management. Literature search on Pubmed for paper published after 1994. Craniopharyngiomas are rare, embryonic malformations of the sellar/parasellar region with low histological grade. Clinical manifestations are related to increased intracranial pressure, visual impairment, and hypothalamic/pituitary deficiencies. If the tumor is favorably localized, therapy of choice is complete resection, with care taken to preserve hypothalamic and optic functions. In patients with unfavorable tumor location (i.e. involvement of hypothalamic areas), recommended therapy is limited hypothalamus-sparing surgical strategy followed by irradiation. Irradiation has proven effective in treatment of recurrences and progression. Surgical lesions and/or anatomical involvement of posterior hypothalamic areas can result in serious sequelae, mainly hypothalamic syndrome. It is crucial that craniopharyngioma be managed as a frequently chronic disease, providing ongoing care of pediatric and adult patients' by experienced multidisciplinary teams in the context of multicenter trials.

Fat embolism syndrome (FES) is a clinical problem arising mainly due to fractures particularly of long bones and pelvis. Not much literature is available about FES from the Indian subcontinent. Thirty-five patients referred/admitted prospectively over a 3-year period for suspected FES to a north Indian tertiary care center and satisfying the clinical criteria proposed by Gurd and Wilson, and Schonfeld were included in the study. Clinical features, risk factors, complications, response to treatment and any sequelae were recorded. The patients (all male) presented with acute onset breathlessness, 36-120 hours following major bone trauma due to vehicular accidents. Associated features included features of cerebral dysfunction (n = 24, 69%), petechial rash (14%), tachycardia (94%) and fever (46%). Hypoxemia was demonstrable in 80% cases, thrombocytopenia in 91%, anemia in 94% and hypoalbuminemia in 59%. Bilateral alveolar infiltrates were seen on chest radiography in 28 patients and there was evidence of bilateral ground glass appearance in 5 patients on CT. Eleven patients required ventilatory assistance whereas others were treated with supportive management. Three patients expired due to associated sepsis and respiratory failure, whereas others recovered with a mean hospital stay of 9 days. No long term sequelae were observed. FES remains a clinical challenge and is a diagnosis of exclusion based only on clinical grounds because of the absence of any specific laboratory test. A high index of suspicion is required for diagnosis and initiating supportive management in patients with traumatic fractures, especially in those having undergone an invasive orthopedic procedure.

Many men diagnosed with prostate cancer (PC) will experience physical and psychosocial late effects of treatment. Their interest/preferences for receiving information about addressing common sequelae is not well understood. We examined long-term PC survivors' level of interest, whether this differed based upon symptomatology, and their preferred coping information source. N=615 PC survivors (3-8 years post-diagnosis) completed a survey on physical and psychological health and their information interests and preferences related to late effects of cancer treatment. Over half of PC survivors reported interest in information about late effects of treatment or sexual health, while approximately a quarter were interested in emotional health information. Survivors preferred to receive information about late effects of treatment from their oncologists, sexual health information from their primary care providers (PCP), oncologist, or written/online resources, and emotional health information from their PCP. Information needs were more commonly reported among men with poorer domain-specific health functioning. Long-term PC survivors report significant interest in receiving information about their physical, sexual, and emotional health. Medical providers caring for these men should inquire about survivors' information needs and future intervention efforts should consider who delivers the information, dependent upon the type of dysfunction reported.

Dental and maxillofacial abnormalities in long-term survivors of childhood cancer: effects of treatment with chemotherapy and radiation to the head and neck

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jaffe, N.; Toth, B.B.; Hoar, R.E.

1984-06-01

Sixty-eight long-term survivors of childhood cancer were evaluated for dental and maxillofacial abnormalities. Forty-five patients had received maxillofacial radiation for lymphoma, leukemia, rhabdomyosarcoma, and miscellaneous tumors. Forty-three of the 45 patients and the remaining 23 who had not received maxillofacial radiation also received chemotherapy. Dental and maxillofacial abnormalities were detected in 37 of the 45 (82%) radiated patients. Dental abnormalities comprised foreshortening and blunting of roots, incomplete calcification, premature closure of apices, delayed or arrested tooth development, and caries. Maxillofacial abnormalities comprised trismus, abnormal occlusal relationships, and facial deformities. The abnormalities were more severe in those patients who received radiationmore » at an earlier age and at higher dosages. Possible chemotherapeutic effects in five of 23 patients who received treatment for tumors located outside the head and neck region comprised acquired amelogenesis imperfecta, microdontia of bicuspid teeth, and a tendency toward thinning of roots with an enlarged pulp chamber. Dental and maxillofacial abnormalities should be recognized as a major consequence of maxillofacial radiation in long-term survivors of childhood cancer, and attempts to minimize or eliminate such sequelae should involve an effective interaction between radiation therapists, and medical and dental oncologists.« less

Outpatient management of pelvic inflammatory disease.

Price, B; Martens, M

2001-08-01

Pelvic inflammatory disease (PID) is a spectrum of inflammatory disorders of the female genital tract involving at least the endrometrium and may include the fallopian tubes, ovaries, and pelvic cavity. Over 1 million women each year are treated for PID in the United States, and it is one of the most serious infections diagnosed in women due to its sequelae. Women with PID acutely experience pain and are at risk for sepsis; however, the significant increases in ectopic pregnancy and infertility are the most disturbing long-term complications. It most often is initiated with an infection by a sexually transmitted disease, but can also involve a variety of pathogenic aerobes and anaerobes secondarily.

Methemoglobinemia Secondary to Topical Benzocaine Application to Gastrostomy Site.

Lipton, Matthew; Szlam, Sarah M; Barker, Kim; Benitez, John G

2016-05-01

Benzocaine is a common topical anesthetic that has the ability to induce methemoglobinemia (MetHgb) in large doses. We describe a 4-year-old girl who received a standard dose of topical benzocaine to her gastrostomy mucosa that resulted in rapid, severe MetHgb. She required intubation, mechanical ventilation, and multiple doses of methylene blue for treatment. The resultant tissue hypoxia from MetHgb caused profound confusion, cyanosis, and myocardial infarction. Although the patient did not sustain any permanent disability, this case demonstrates the need for emergency providers to rapidly identify and treat MetHgb to reverse tissue hypoxia and prevent long-term sequelae.

Advancement in correction or palliation of congenital cardiac lesions has greatly improved the lifespan of congenital heart disease patients, resulting in a rapidly growing adult congenital heart disease (ACHD) population. As this group has increased in number and age, emerging science has highlighted the systemic nature of ACHD. Providers caring for these patients are tasked with long-term management of multiple neurologic, pulmonary, hepatic, renal, and endocrine manifestations that arise as syndromic associations with congenital heart defects or as sequelae of primary structural or hemodynamic abnormalities. In this review, we outline the current understanding and recent research into these extra-cardiac manifestations. Copyright © 2016 Elsevier Inc. All rights reserved.

The effect of pharmaceutical intervention on lipid profile in polycystic ovary syndrome.

Diamanti-Kandarakis, E; Kandaraki, E; Christakou, C; Panidis, D

2009-07-01

The polycystic ovary syndrome (PCOS), a prevalent endocrinopathy of women, has been associated with a clustering of adverse metabolic features, which co-exist with reproductive dysfunction. Lipid abnormalities are very common in lean as well as obese women with PCOS and should be cautiously considered in the therapeutic management of the syndrome. Clinicians should also critically assess the lipidemic effect of pharmaceutical intervention, primarily aimed at hyperandrogenism, anovulation or insulin resistance. Because dyslipidemia may contribute to long-term cardiometabolic and reproductive sequelae in PCOS, it should be considered as an additional therapeutic target when these patients are assigned to appropriate pharmaceutical treatment.

Aims We aim to review the results, complications and outcomes of a single surgeon's series of lower limb lengthening in patients with achondroplasia. Methods Ten achondroplastic children underwent limb lengthening. The patients, medical records and radiographs were reviewed. Results The average age at the time of the index operation was 7.8 years. A single surgeon undertook all procedures. The average total length gain was 20.5 cm. The commonest complication was a fractured femur after removal of the frame. Conclusion Although complication rates were high (70%), none were left with any long-term sequelae and all were pleased with the results. PMID:25829758

2016-07-01

High-pressure injection hand injuries are often overlooked, with severe complications owing to the acute inflammatory response. Prognosis for depends on the type of material injected, location of injection, involved pressure, and timing to surgical decompression and debridement. Acute management involves broad-spectrum antibiotics, tetanus prophylaxis, emergent decompression within 6 hours, and complete removal of the injected material. Most patients have residual sequelae of stiffness, pain, sensation loss, and difficulties in returning to work. The hand surgeon's role is prompt surgical intervention, early postoperative motion, and education of patient and staff regarding short- and long-term expectations. Copyright © 2016 Elsevier Inc.

Acro-dermato-ungual-lacrimal-tooth (ADULT) syndrome is a rare form of autosomal dominant ectodermal dysplasia due to mutations in the TP63 gene, a locus that has also been implicated in other syndromic forms of ectodermal dysplasia. It shares many phenotypic characteristics with other TP63 gene mutation syndromes, often making an accurate diagnosis difficult. Long-term management and follow-up of the various sequelae of ectodermal dysplasia require an accurate diagnosis. We report a familial case of ADULT syndrome in a daughter, mother, and son and provide a brief review of the clinical characteristics of this syndrome. © 2016 Wiley Periodicals, Inc.

The elimination of scabies: a task for our generation.

McLean, Florence E

2013-10-01

Scabies prevalence remains unacceptably high in many regions throughout the world. Infestation with scabies significantly impacts quality of life and is linked to pyoderma and consequently to severe long-term sequelae such as post-streptococcal glomerulonephritis. In the past, control programs using topical treatments have met with poor compliance; however, the highly effective oral agent ivermectin may offer a new paradigm in scabies management. Problems still exist with insensitive diagnostic tests, questions concerning mite reservoirs, and restrictions on who can receive ivermectin. Despite these difficulties, the elimination of scabies in communities worst affected may soon be possible. © 2013 The International Society of Dermatology.

Late sequela after treatment of childhood low-grade gliomas: a retrospective analysis of 69 long-term survivors treated between 1983 and 2003.

2006-06-01

The aim of the present study was to evaluate the spectrum of late effects in a large cohort of pediatric patients with low-grade gliomas (WHO grade I and II) during an observation period of 20 years. Eighty-seven patients with low-grade gliomas grouped according to tumor location (cerebellum: n=28; cerebral hemispheres: n=21; central midline: n=15; brainstem: n=12; tectum: n=5; other locations: n=6) were evaluated for tumor- and/or treatment-related late effects by analysis of medical and computer records, and personal interviews. Seventy patients underwent neurosurgery, 29 patients received additional radiotherapy and 20 additional chemotherapy. Median follow-up of survivors is 96 months with an overall survival of 79% (cerebellum: 89%; cerebral hemispheres: 95%; central midline: 80%; brainstem: 25%; tectum: 100%; other locations: 66%). Chronic medical problems (mild ataxia to multiple severe neuroendocrine deficits) are observed in 100% of patients with brainstem/central midline tumors and in 40-50% of patients with low-grade gliomas of other locations. Endocrine deficiencies were observed in 15/17 (88%) of long-term survivors who received radiotherapy. In contrast, none of the patients who underwent surgery only had endocrine deficiencies. Seven long-term survivors (10.1%) are severely disabled with permanent need of medical help. Tumor- and treatment-related late effects are common in patients with low-grade gliomas with the most severe occurring in patients with brainstem or central midline tumors. As long-term survival is excellent in patients with low-grade gliomas except for tumors located in the brainstem, future treatment studies should focus on avoiding long-term late effects.

Cerebrospinal fluid kynurenine and kynurenic acid concentrations are associated with coma duration and long-term neurocognitive impairment in Ugandan children with cerebral malaria.

One-fourth of children with cerebral malaria (CM) retain cognitive sequelae up to 2 years after acute disease. The kynurenine pathway of the brain, forming neuroactive metabolites, e.g. the NMDA-receptor antagonist kynurenic acid (KYNA), has been implicated in long-term cognitive dysfunction in other CNS infections. In the present study, the association between the kynurenine pathway and neurologic/cognitive complications in children with CM was investigated. Cerebrospinal fluid (CSF) concentrations of KYNA and its precursor kynurenine in 69 Ugandan children admitted for CM to Mulago Hospital, Kampala, Uganda, between 2008 and 2013 were assessed. CSF kynurenine and KYNA were compared to CSF cytokine levels, acute and long-term neurologic complications, and long-term cognitive impairments. CSF kynurenine and KYNA from eight Swedish children without neurological or infectious disease admitted to Astrid Lindgren's Children's Hospital were quantified and used for comparison. Children with CM had significantly higher CSF concentration of kynurenine and KYNA than Swedish children (P < 0.0001 for both), and CSF kynurenine and KYNA were positively correlated. In children with CM, CSF kynurenine and KYNA concentrations were associated with coma duration in children of all ages (P = 0.003 and 0.04, respectively), and CSF kynurenine concentrations were associated with worse overall cognition (P = 0.056) and attention (P = 0.003) at 12-month follow-up in children ≥5 years old. CSF KYNA and kynurenine are elevated in children with CM, indicating an inhibition of glutamatergic and cholinergic signaling. This inhibition may lead acutely to prolonged coma and long-term to impairment of attention and cognition.

In the 1980s, villages in the Kurdistan region of Iraq were exposed to chemical weapons (CWs), which killed and injured thousands of civilians. There has been no clinical assessment of the long-term effects of CWs exposure on those injured. We report the first such evaluation of CW effects on long-term health of children. Patients from the CW-exposed areas were interviewed to assess previous and current clinical history and underwent clinical examination. The status of organs known to be targets of CWs, including skin, eyes, respiratory and neuromuscular systems, was assessed. Children of similar age and social background, but with no history of CW exposure, were selected as a control population. Results showed that 70% of children in the CWs group had chronic health problems in contrast to 3.3% in the unexposed group ( p < 0.0001). Fifty-five per cent of the CW-exposed group had long-term visual impairment but none in the unexposed population. Thirty-six per cent of the CW-exposed group had chronic dermatological conditions compared with 0.8% of the unexposed group ( p < 0.0001), 31% of the CWs group had neurological sequelae compared with 0.4% of the unexposed group ( p < 0.0001) and 51% of the CWs group had long-term respiratory problems compared with 1.5% of the unexposed group ( p < 0.0001). Respiratory complaints including asthma, chronic bronchitis and bronchiectasis were particularly common. Our study suggests that CWs used were probably a combination of sulphur mustard and organophosphate nerve agents. Results also indicate that the prevalence of acute and chronic health problems following exposure to CW agents appear to be higher in children compared with reported data in adults.

1988-01-01

This trial was designed to evaluate the efficacy of EPOREC 1 500 magnets as an adjuvant to rehabilitation following peripheral facial paralysis. Magnetotherapy is used in many other specialties, and in particular in rheumatology. The properties of repulsion between identical poles were used to decrease the effect of sequelae in the form of contractures on the facial muscles. There were two groups of 20 patients: one group with physiotherapy only and the other with standard rehabilitation together with the use of magnets. These 40 patients had facial paralysis of various origins (trauma, excision of acoustic neuroma, Bell's palsy etc). Obviously all patients had an intact nerve. It was at the time of the development of contractures that magnets could be used in terms of evaluation of their efficacy of action on syncinesiae, contractures and spasticity. Magnets were worn at night for a mean period of six months and results were assessed in terms of disappearance of eye-mouth syncinesiae, and in terms of normality of facial tone. Improvement and total recovery without sequelae were obtained far more frequently in the group which wore magnets, encouraging us to continue along these lines.

Ovarian Damage During Chemotherapy in Autoimmune Diseases: Broad Health Implications beyond Fertility

Marder, Wendy; Fisseha, Senait; Ganser, Martha A.; Somers, Emily C.

2012-01-01

Women with autoimmune diseases such as lupus, scleroderma, and vasculitis receiving cyclophosphamide for severe disease manifestations risk primary ovarian insufficiency (POI) due to gonadotoxicity of this therapy. In addition to loss of reproductive potential, POI is associated with increased risk of morbidity and mortality. Practitioners caring for women requiring gonadotoxic therapies should be familiar with long-term health implications of POI and strategies for ovarian preservation. Accumulating evidence supports the effectiveness of adjunctive gonadotropin releasing hormone analog (GnRH-a) for ovarian protection during gonadotoxic therapy in cancer and autoimmune populations. GnRH-a is less costly and invasive than assisted reproductive technologies used for achievement of future pregnancies, but is not Food and Drug Administration approved for ovarian preservation. This review focuses on POI comorbidities and strategies for mitigation of related sequelae, which can accumulate over decades of hypoesteogenism. These issues are arguably more pronounced for women with chronic autoimmune diseases, in whom superimposed POI further heightens risks of cardiovascular disease and osteoporosis. Therefore, even if future pregnancy is not desired, ovarian protection during gonadotoxic therapy should be a major goal of disease management. PMID:23970822

Non-surgical management of obstructive sleep apnoea: a review.

PubMed

Whitla, Laura; Lennon, Paul

2017-02-01

Obstructive sleep apnoea is common in children and, if untreated, can lead to multiple medical sequelae. The Childhood Adenotonsillectomy Trial demonstrated benefit from early surgical intervention, but rapid access to such treatment is not always available. To examine the recent literature on non-surgical aspects of the management of paediatric obstructive sleep apnoea (OSA). The English language literature was searched for articles on the conservative management of OSA. In mild cases of OSA, intra-nasal steroids and other anti-inflammatory medications may give relief in mild cases of OSA, but the long-term safety of these treatments has not been established. Weight loss in obese children has been shown to be effective in selected patients but is limited in practice. Non-invasive ventilation may be effective but compliance can be a major obstacle. Oral appliances are effective by stenting the pharyngeal airway, but research in this area is limited. There are number of potential, if not proven, alternative management strategies for children with OSA, which could be considered in the absence of early surgical intervention.

The intergenerational transfer of psychosocial risk: mediators of vulnerability and resilience.

PubMed

Serbin, Lisa A; Karp, Jennifer

2004-01-01

The recurrence of social, behavioral, and health problems in successive generations of families is a prevalent theme in both the scientific and popular literatures. This review discusses recent conceptual models and findings from longitudinal studies concerning the intergenerational transfer of psychosocial risk, including intergenerational continuity, and the processes whereby a generation of parents may place their offspring at elevated risk for social, behavioral, and health problems. Key findings include the mediational effects of parenting and environmental factors in the transfer of risk. In both girls and boys, childhood aggression and antisocial behavior appear to predict long-term trajectories that place offspring at risk. Sequelae of childhood aggression that may threaten the well-being of offspring include school failure, adolescent risk-taking behavior, early and single parenthood, and family poverty. These childhood and adolescent behavioral styles also predict harsh, aggressive, neglectful, and unstimulating parenting behavior toward offspring. Buffering factors within at-risk families include maternal educational attainment and constructive parenting practices (e.g., emotional warmth, consistent disciplinary practices, and cognitive scaffolding). These findings highlight the potential application and relevance of intergenerational studies for social, educational, and health policy.

Treatment of medulloblastoma in children fails in approximately 30% of patients, and is often accompanied by severe late sequelae. Therefore, more effective drugs are needed that spare normal tissue and diminish long-term side effects. Since radiotherapy plays a pivotal role in the treatment of medulloblastoma, we set out to identify novel drugs that could potentiate the effect of ionizing radiation.Thereto, a small molecule library, consisting of 960 chemical compounds, was screened for its ability to sensitize towards irradiation. This small molecule screen identified the flavonoid quercetin as a novel radiosensitizer for the medulloblastoma cell lines DAOY, D283-med, and, to a lesser extent, D458-med at low micromolar concentrations and irradiation doses used in fractionated radiation schemes. Quercetin did not affect the proliferation of neural precursor cells or normal human fibroblasts. Importantly, in vivo experiments confirmed the radiosensitizing properties of quercetin. Administration of this flavonoid at the time of irradiation significantly prolonged survival in orthotopically xenografted mice. Together, these findings indicate that quercetin is a potent radiosensitizer for medulloblastoma cells that may be a promising lead for the treatment of medulloblastoma in patients.

Qualitative studies of families with children who have cancer or other serious illnesses have found that families often come to view their child and their lives as normal. They manage illness-related demands using family management styles that sustain usual patterns of family and child functioning. Few studies have addressed the family management styles of families who express less satisfaction with family and child functioning or who are identified by health care professionals as having difficulty with family functioning. Such families are likely to be overrepresented among those whose children are being treated for brain tumors that entail extremely burdensome treatments as well as a range of unfavorable prognoses and long-term sequelae. In fact, little is known about how these families manage on a day-to-day basis and how the interdisciplinary team can best provide supportive care to optimize their functioning. The purpose of this article is to present the Family Management Styles Framework as a tool that is useful in both clinical practice and research for assessing families who have children with cancer, including those with brain tumors.

Survival with a good quality of life after cardiac arrest continues to be abysmal. Coordinated resuscitative care does not end with the effective return of spontaneous circulation (ROSC)-in fact, quite the contrary is true. Along with identifying and appropriately treating the precipitating cause, various components of the post-cardiac arrest syndrome also require diligent observation and management, including post-cardiac arrest neurologic injury and myocardial dysfunction, systemic ischemia-reperfusion phenomenon with potential consequent multiorgan failure, and the various sequelae of critical illness. There is growing evidence that an early invasive approach to coronary reperfusion with percutaneous coronary intervention, together with active targeted temperature management and optimization of hemodynamic, ventilator, and metabolic parameters, may improve survival and neurologic outcomes in cardiac arrest survivors. Neuroprognostication is complex, as are survivorship issues and long-term rehabilitation. Our paramedics, emergency physicians, and resuscitation specialists are all to be congratulated for ever-increasing success with ROSC… but now the real work begins.

Current safety issues with quadrivalent meningococcal conjugate vaccines.

PubMed

Myers, Tanya R; McNeil, Michael M

2018-05-04

Invasive meningococcal disease, although rare, can present as sudden, life-threatening disease with high risk of mortality or severe long-term sequelae. The main prevention strategy for invasive meningococcal disease in the United States is the routine vaccination of adolescents and other persons at increased risk of meningococcal disease with quadrivalent meningococcal conjugate vaccines. Two such vaccines are currently licensed and available in the United States, Menactra® (Sanofi Pasteur) and Menveo® (GlaxoSmithKline), and usage in the adolescent population has steadily increased since their introduction. Although early reports raised concerns about a possible association of Menactra with Guillain-Barré syndrome, a comprehensive safety review determined that if such risk existed it was no more than 0.66 cases per 1 million vaccinations. More recently, a study found an elevated risk of Bell's palsy when Menveo was administered concomitantly with other vaccines but no association was found when the vaccine was administered alone. In this commentary, we describe the current state of knowledge with respect to the safety of quadrivalent meningococcal conjugate vaccines, and we identify potential areas for safety research for these vaccines.

Pathogenesis and Pathophysiology of Pneumococcal Meningitis

2011-01-01

Summary: Pneumococcal meningitis continues to be associated with high rates of mortality and long-term neurological sequelae. The most common route of infection starts by nasopharyngeal colonization by Streptococcus pneumoniae, which must avoid mucosal entrapment and evade the host immune system after local activation. During invasive disease, pneumococcal epithelial adhesion is followed by bloodstream invasion and activation of the complement and coagulation systems. The release of inflammatory mediators facilitates pneumococcal crossing of the blood-brain barrier into the brain, where the bacteria multiply freely and trigger activation of circulating antigen-presenting cells and resident microglial cells. The resulting massive inflammation leads to further neutrophil recruitment and inflammation, resulting in the well-known features of bacterial meningitis, including cerebrospinal fluid pleocytosis, cochlear damage, cerebral edema, hydrocephalus, and cerebrovascular complications. Experimental animal models continue to further our understanding of the pathophysiology of pneumococcal meningitis and provide the platform for the development of new adjuvant treatments and antimicrobial therapy. This review discusses the most recent views on the pathophysiology of pneumococcal meningitis, as well as potential targets for (adjunctive) therapy. PMID:21734248

Infection of hamsters with the murine flavivirus Modoc results in (meningo)encephalitis, which is, during the acute phase, frequently associated with flaccid paralysis, as also observed in patients with West Nile virus encephalitis. Twenty percent of the hamsters that recover from the acute encephalitis develop life-long neurological sequelae, reminiscent of those observed, for example, in survivors of Japanese encephalitis. Magnetic resonance imaging and histology revealed severe lesions predominantly located in the olfactory-limbic system, both in hamsters with acute encephalitis as in survivors. Prominent pathology was also detected in the spinal cord of hamsters with paralysis. Modoc virus infections in hamsters provide a unique model for the study of encephalitis, a poliomyelitis-like syndrome and neurological sequelae following flavivirus infection.

Evidence for the Risks and Consequences of Adolescent Cannabis Exposure.

PubMed

Levine, Amir; Clemenza, Kelly; Rynn, Moira; Lieberman, Jeffrey

2017-03-01

This review of the scientific literature examines the potential adult sequelae of exposure to cannabis and related synthetic cannabinoids in adolescence. We examine the four neuropsychiatric outcomes that are likely most vulnerable to alteration by early cannabinoid use, as identified within both the clinical and preclinical research: cognition, emotional functioning, risk for psychosis, and addiction. A literature search was conducted through PubMed, PsychInfo, and Google Scholar with no publication date restrictions. The search terms used were "adolescent" and "adult," and either "cannabis," "marijuana," "delta-9-tetra-hydrocannabinol," or "cannabinoid," which was then crossed with one or more of the following terms: "deficit," "impairment," "alteration," "long-term," "persistent," "development," "maturation," and "pubescent." The majority of the clinical and preclinical data point to a strong correlation between adolescent cannabinoid exposure and persistent, adverse neuropsychiatric outcomes in adulthood. Although the literature supports the hypothesis that adolescent cannabis use is connected to impaired cognition and mental health in adults, it does not conclusively demonstrate that cannabis consumption alone is sufficient to cause these deficits in humans. The animal literature, however, clearly indicates that adolescent-onset exposure to cannabinoids can catalyze molecular processes that lead to persistent functional deficits in adulthood, deficits that are not found to follow adult-onset exposure and that model some of the adverse outcomes reported in humans among adult populations of early-onset cannabis users. Based on the data in the current literature, a strong association is found between early, frequent, and heavy adolescent cannabis exposure and poor cognitive and psychiatric outcomes in adulthood, yet definite conclusions cannot yet be made as to whether cannabis use alone has a negative impact on the human adolescent brain. Future research will require animal models and longitudinal studies to be carefully designed with a focus on integrating assessments of molecular, structural, and behavioral outcomes in order to elucidate the full range of potential adverse and long-term consequences of cannabinoid exposure in adolescence.

Effect of central and ovarian endocrine disturbances on the female genital tract--clinical signs and symptoms.

PubMed

Sillem, M; Rabe, T; Runnebaum, B

1997-01-01

Disorders of the female genital tract caused by endocrine disturbances commonly lead to two presenting complaints: dysfunctional uterine bleeding and infertility. In oestrogen deficiency, sequelae of vaginal atrophy may also be present. The common pathogenic "turntable" of these clinical signs is an impaired ovarian function, for which primary (i.e. intraovarian) and secondary (i.e. resulting from dysfunctions of other endocrine systems) causes are known. Primary ovarian failure can be the result of gonadal dysgenesis or premature menopause. Secondary ovarian dysfunction may be caused by hypothalamic-pituitary dysregulation, hyperprolactinaemia, thyroid disorders, and hyperandrogenaemia, which often also has an intraovarian component. For clinical considerations, several severities of ovarian dysfunction can be distinguished, ranging from corpus luteum insufficiency which is only relevant for the selection of infertility treatment to the complete absence of ovarian steroidogenesis leading to severe long term sequelae of the skeletal, cardiovascular and probably central nervous systems. Diagnosis and differential diagnosis are made by clinical examination, vaginal ultrasound, hormone assays, curettage and laparoscopy. Rarely, additional techniques like magnetic resonance imaging of the pituitary or the adrenals, or sequential catheterization of the inferior vena cava are needed.

Non-operative management of rectal cancer: understanding tumor biology.

PubMed

Wei, Iris H; Garcia-Aguilar, Julio

2018-05-24

The management of locally advanced rectal cancer involves a combination of chemotherapy, chemoradiation, and surgical resection to provide excellent local tumor control and overall survival. However, aspects of this multimodality approach are associated with significant morbidity and longterm sequelae. In addition, there is growing evidence that patients with a clinical complete response to chemotherapy and chemoradiation treatments may be safely offered initial non-operative management in a rigorous surveillance program. Developing effective methods, such as molecular biomarkers, to predict a patient's response to therapies are therefore needed to help guide personalized treatment strategies. The treatment of locally advanced rectal cancer focuses on a multimodality approach of systemic chemotherapy, radiation, and total mesorectal excision to maximize oncologic outcomes. While combined modality treatment for LARC results in excellent local tumor control and patient survival, the treatments are associated with significant morbidity and long-term functional complications that can impair quality of life. In addition, the tumor response to neoadjuvant therapy is quite variable.2 Weighed against the morbidity and significant sequelae of rectal resection, recognizing how to best optimize nonoperative strategies without compromising oncologic outcomes is critical to our understanding and treatment of this disease.

Clinical Options for the Treatment of Urinary Tract Infections in Children

2014-01-01

Urinary Tract Infections (UTI) are a common cause of childhood febrile illness with 7% of girls and 2% of boys having a symptomatic culture positive UTI by the age of six years. Although there are conflicting views on the long term sequelae of UTI, as well as the place of prophylaxis, the universal aims of treatment of childhood UTI remain those of symptom alleviation, prevention of systemic infection and short and longer term complications. There is good evidence of historical and emerging resistance patterns, therefore rationalisation of prescription patterns by knowledge of sensitivities coupled with re-examination of empirical antibiotic choices is clearly important. Local formularies should reflect geographical resistance patterns along with best evidence on the duration and choice of antibiotic in order to maximize therapeutic effect, while minimizing the development of resistant strains.

This study aimed to develop a non-invasive method for in vivo measurement of the transepithelial potential difference in the canine small bowel and to evaluate this parameter in small bowel autotransplants. In group 0 (control group, n = 4), two intestinal loops were created without disturbing their vascular, neural, and lymphatic supplies. In group I (successful autotransplants, n = 11), two heterotopic small bowel loops were constructed. Long term functional sequelae of vascular, neural, and lymphatic division were studied. Group II (n = 6) consisted of dogs with unsuccessful autotransplants suffering thrombosis of the vascular anastomosis, which resulted in ischaemic small bowel autografts. In group I, values of spontaneous transepithelial potential difference, an index of base line active electrolyte transport, were significantly lower compared with group 0 (p less than 0.05), probably as a result of denervation of the autotransplants. Both theophylline and glucose stimulated potential difference responses, measuring cyclic adenosine monophosphate mediated chloride secretion and sodium coupled glucose absorption respectively, showed negative luminal values in group I at all time points after transplantation. These transepithelial potential difference responses diminished progressively with time. From day 21 onwards both theophylline and glucose stimulated potential difference responses were significantly less than the corresponding responses at day seven (p less than 0.05). Morphometric analysis showed that the reduction of transepithelial potential difference responses preceded degenerative mucosal changes in the heterotopic small bowel autografts. In group II, potential difference responses to theophylline and glucose showed positive luminal values (p<0.01 v group I), probably as a result of passive potassium effusion from necrotic enterocytes.

2017-01-01

Obstructive sleep apnea (OSA) is a prevalent sleep-disordered breathing with potential long-term major neurocognitive and cardiovascular sequelae. The pathophysiology of OSA varies between individuals and is composed of different underlying mechanisms. Several components including the upper airway anatomy, effectiveness of the upper airway dilator muscles such as the genioglossus, arousal threshold of the individual, and inherent stability of the respiratory control system determine the pathogenesis of OSA. Their recognition may have implications for the perioperative health care team. For example, OSA patients with a high arousal threshold are likely to be sensitive to sedatives and narcotics with a higher risk of respiratory arrest in the perioperative period. Supplemental oxygen therapy can help to stabilize breathing in OSA patients with inherent respiratory instability. Avoidance of supine position can minimize airway obstruction in patients with a predisposition to upper airway collapse in this posture. In this review, the clinically relevant endotypes and phenotypes of OSA are described. Continuous positive airway pressure (CPAP) therapy is the treatment of choice for most patients with OSA but tolerance and adherence can be a problem. Patient-centered individualized approaches to OSA management will be the focus of future research into developing potential treatment options that will help decrease the disease burden and improve treatment effectiveness.

Shah, Chirag; Vicini, Frank A., E-mail: fvicini@beaumont.edu

As more women survive breast cancer, long-term toxicities affecting their quality of life, such as lymphedema (LE) of the arm, gain importance. Although numerous studies have attempted to determine incidence rates, identify optimal diagnostic tests, enumerate efficacious treatment strategies and outline risk reduction guidelines for breast cancer-related lymphedema (BCRL), few groups have consistently agreed on any of these issues. As a result, standardized recommendations are still lacking. This review will summarize the latest data addressing all of these concerns in order to provide patients and health care providers with optimal, contemporary recommendations. Published incidence rates for BCRL vary substantially withmore » a range of 2-65% based on surgical technique, axillary sampling method, radiation therapy fields treated, and the use of chemotherapy. Newer clinical assessment tools can potentially identify BCRL in patients with subclinical disease with prospective data suggesting that early diagnosis and management with noninvasive therapy can lead to excellent outcomes. Multiple therapies exist with treatments defined by the severity of BCRL present. Currently, the standard of care for BCRL in patients with significant LE is complex decongestive physiotherapy (CDP). Contemporary data also suggest that a multidisciplinary approach to the management of BCRL should begin prior to definitive treatment for breast cancer employing patient-specific surgical, radiation therapy, and chemotherapy paradigms that limit risks. Further, prospective clinical assessments before and after treatment should be employed to diagnose subclinical disease. In those patients who require aggressive locoregional management, prophylactic therapies and the use of CDP can help reduce the long-term sequelae of BCRL.« less

Sequelae of abdominal radiation and their medical management

As various chemotherapeutic agents are added to treatment routines, the possibility of adverse effects is appreciably increased, particularly in those organs for which the agents have specific toxicity. Symptoms most commonly associated with radiation sickness, such as malaise, anorexia, nausea, vomiting, diarrhea, dysphagia, dermatitis, and depleted hemopoietic elements, are usually seen late in the course of radiation therapy or shortly thereafter. Consequently, they are managed by the physician in charge of radiation or the patient's referring physician. The general physician may be concerned with symptoms arising from delayed organ pathology. These symptoms may arise in many tissues that are stillmore » considered somewhat radioresistant, but secondary to sequelae arising because of connective tissue changes from obliterative narrowing of the finer vasculature. Radiation may be only one of several possible causes, and the symptoms of sequelae may appear only after a long latent period, so that the previous radiation may not be considered in the differential diagnosis unless a detailed history is taken. The medical management of these sequelae is, in general, similar to that used for the pathology produced in these organs by other agents.« less

The combination of lesions of the penile urethra and the corpus cavernosum is rare and is likely to worsen the immediate and long-term prognosis. To assess the late effects of penile fractures complicated by urethral rupture treated by immediate surgical intervention. Fourteen patients with concomitant urethral rupture were treated surgically at our center. Those patients were seen in the outpatient follow-up clinic and were re-evaluated. Sexual Health Inventory for Men questionnaire, local examination, uroflowmetry and penile color Doppler ultrasound. The most common cause of penile fracture is sexual intercourse (50%). The site of tunical tear was in the proximal shaft of the penis in 3 patients (21%) and in the mid of the shaft in 11 patients (79%). Urethral injury was localized at the same level as the corpus cavernosum tear in all cases; and it was partial in 11 cases and complete in 3. Long-term follow-up (mean=90 months) was available for 12 patients; among whom there was no complications in 4 (33%), painful erection in 1 (8%), erectile dysfunction in 2 (17%), and palpable fibrous nodule in 5 (47%). All patients had a normal urinary flow except one who developed relative urethral narrowing that required regular dilatation for 1 month. The urethral injury complicating penile fracture is often partial and localized at the level of the corpora cavenosa tear. Standard treatment consists of immediate surgical repair of both urethral and corporal ruptures with no harmful long-term sequelae on urethral and erectile function in most of patients. © 2010 International Society for Sexual Medicine.

We determined the value of clinical and radiological findings in diagnosis of false penile fracture. Also, the long-term outcome of conservative and surgical treatment of such patients was evaluated. Seventeen patients with false penile fracture were treated conservatively (3 patients) and surgically (14 patients) at our center. Medical records were retrospectively reviewed for etiology, symptoms, signs of physical examination, and information on findings of surgical exploration. Data on erectile function and penile sequelae were obtained during follow-up using the Sexual Health Inventory for Men (SHIM) questionnaire and local examination. The most common cause of false penile fracture is sexual intercourse (76.5%). False fracture was suspected in 3 patients who presented with small hematoma and slow post-trauma detumescence; intact tunicas were diagnosed by magnetic resonance imaging (MRI) in all of them and were managed conservatively. Surgical penile exploration was performed in 14 cases, in whom preoperative ultrasound was done in 6, and it was false positive for presence of tunical tear in 50%. Exploration revealed nonspecific dartos bleeding in 9 cases and avulsed superficial dorsal vein in 5. Long-term follow-up (mean=93 months) was available for 16 patients, among whom there was no complications. In most cases, false penile fracture is indistinguishable from true penile fracture either clinically or radiologically. In atypical cases, MRI seems to be a promising modality for diagnosis of such patients. The long-term outcome of conservative and surgical treatment is excellent. Copyright (c) 2010 Elsevier Inc.

Fatigue is a common symptom with numerous causes. Severe fatigue is thought to be an important manifestation of post-treatment Lyme disease syndrome. The frequency with which severe fatigue occurs as a long-term sequela in prospectively followed patients with Lyme disease is unknown. Patients with culture-confirmed Lyme disease who originally presented with erythema migrans have been evaluated annually in a prospective study to determine their long-term outcome. In 2011-2013, subjects were evaluated for fatigue using an 11-item Fatigue Severity Scale (FSS-11) that has been used in studies of post-treatment Lyme disease syndrome. An FSS-11 score of ≥4.0 is indicative of severe fatigue. A total of 100 subjects were assessed, 52% of whom were male; the mean age was 64.9 years (range, 42-86 years). The mean duration of follow-up was 15.4 years (range, 11-20 years). Nine subjects had severe fatigue but in none as a consequence of Lyme disease. Only 3 subjects were thought to possibly have persistent fatigue from Lyme disease. The FSS-11 value for these 3 individuals was less than 4, averaging 2.27, and none had functional impairment. Severe fatigue was found in 9 patients (9%) with culture-confirmed early Lyme disease at 11 to 20 years after presentation, but was due to causes other than Lyme disease. Fatigue of lesser severity was possibly due to Lyme disease, but was found in only 3% of 100 patients, and therefore is rarely a long-term complication of this infection.

Nosocomial and ventilator associated pneumonias that plague critically ill, elderly and long-term care residents could be reduced with effective oral hygiene practices facilitated collaboratively between nurses and dental hygienists. Nosocomial pneumonias, specifically aspiration pneumonias and ventilator-associated pneumonias in the elderly and infirm have become a major health care issue, The provision of oral care in hospital and hospital-like facilities presents challenges that can prevent patients from receiving optimal oral care One sequela can be aspiration pneumonia which ranks first in mortality and second in morbidity among all nosocomial infections. Since aspiration pneumonia is linked to the colonization of oral bacteria in dental plaque and biofilm, it is time to look for creative solutions to integrating the expertise of dental hygienists into health care teams in these institutional settings. A comprehensive review of the literature was conducted regarding the etiology and prevalence of health care related pneumonias. Evidence describing the challenges and barriers that the nurses, nursing staff, and dental hygienists face in the provision of oral care in hospitals and long-term care facilities is provided. Intercollaborative solutions to providing optimal oral care in hospitals and long-term care facilities are suggested. Dental hygienists have the expertise and practice experience to provide oral care in hospitals, long-term care and residential facilities. They can contribute to solving oral care challenges through intercollaboration with other health care team members. Yet, there are long-standing systemic barriers that must be addressed in order to provide this optimal care. Dental hygienists becoming better assimilated within the total health care team in hospital and residential facilities can positively impact the suffering, morbidity and mortality associated with aspiration pneumonias.

2012-12-01

To review what is understood about the pathophysiology of polycystic ovarian syndrome (PCOS), the diagnostic challenges of PCOS in adolescent women, associated risk factors, as well as the best evidence-based treatment options for adolescence. Diagnosing PCOS in adolescents requires a unique set of criteria for which no single marker currently exists. Adolescents at high risk for developing the syndrome are congenital virilization, low birth weight, premature pubarche, central precocious puberty, large for gestational age girls born to overweight mothers, obesity syndromes, insulin-resistant features, and girls born to parents with PCOS, central obesity, or diabetes in whom PCOS ought to be suspected when associated with irregular menses. Insulin, hyperandrogenemia, and adipocytokines are integral players in the pathophysiology of PCOS. PCOS may be an inheritable trait; however, no gene has yet been identified. Quality of life remains a concern for young women with PCOS. Lifestyle modifications geared to prevent long-term sequelae remain the first-line treatment in conjunction with oral contraceptive pills. Identifying PCOS in adolescents remains a diagnostic dilemma, but early intervention and treatment can improve long-term health.

Cerebral malaria as a risk factor for the development of epilepsy and other long-term neurological conditions: a meta-analysis.

Christensen, Stephanie S; Eslick, Guy D

2015-04-01

Cerebral malaria (CM) is the most common and severe acute neurological manifestation of Plasmodium falciparum malaria. Children living in malaria-endemic areas of sub-Saharan Africa are at the highest risk of developing CM, and the long-term effect of CM on neurological function is uncertain. We conducted a meta-analysis to quantitatively assess the association between CM and development of long-term neurological impairment. We performed a systematic search through PubMed (including MEDLINE; 1946 to December 2014) and EMBASE (1974 to January 2015) to identify relevant articles. Eligible studies assessed the association between CM and neurological sequelae and were included if they met the criteria allowing a complete extraction of data. Eight studies were included in the final analysis, and in total, 2005 individuals were analysed (cases: n=842, controls: n=1163), most of whom were children. CM was associated with an increased risk of epilepsy (OR 4.68, 95% CI: 2.52-8.70), an increased risk of intelligence quotient (IQ) impairment (OR 4.72, 95% CI: 0.78-28.49), an increased risk of neurodisabilities (OR 16.16, 95% CI: 1.34-195.45), and an increased risk of behavioural disorder (OR 8.47, 95% CI: 2.75-26.04). Our findings suggest that children who survive CM are at increased risk of long-term neurological adverse outcome, including epilepsy. This may present a major public health problem in terms of education and development in malaria-endemic areas. Measures to avoid neurological morbidity are warranted. © The Author 2015.

Transcatheter aortic valve replacement can be an effective, reliable treatment for severe aortic stenosis in surgically high-risk or ineligible patients. However, various sequelae like coronary artery obstruction can occur, not only in the long term, but also immediately after the procedure. We present the case of a 78-year-old woman whose left main coronary artery became obstructed with calculus 2 hours after the transfemoral implantation of an Edwards Sapien XT aortic valve. Despite percutaneous coronary intervention in that artery, the patient died. This case reminds us that early recognition of acute coronary obstruction and prompt intervention are crucial in patients with aortic stenosis who have undergone transcatheter aortic valve replacement.

Delirium is the most common psychiatric syndrome found in the general hospital setting, with an incidence as high as 87% in the acute care setting. Delirium is a neurobehavioral syndrome caused by the transient disruption of normal neuronal activity secondary to systemic disturbances. The development of delirium is associated with increased morbidity, mortality, cost of care, hospital-acquired complications, placement in specialized intermediate and long-term care facilities, slower rate of recovery, poor functional and cognitive recovery, decreased quality of life, and prolonged hospital stays. This article discusses the epidemiology, known etiological factors, presentation and characteristics, prevention, management, and impact of delirium. Copyright © 2017 Elsevier Inc.

Diagnosis of adolescent polycystic ovary syndrome.

PubMed

Hardy, Tristan S E; Norman, Robert J

2013-08-01

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age and is increasingly recognized as a disorder manifesting in the peripubertal and adolescent period. Diagnosis in the adolescent is difficult due to the high background rate of menstrual irregularity, the high prevalence of polycystic ovarian morphology and hyperandrogenic features in this population. Recent guidelines suggest that menstrual irregularity for over two years, reduced reliance on ultrasound diagnosis of polycystic ovarian morphology, and accurate assessment of hyperandrogenic and metabolic features are suitable strategies for the diagnosis of PCOS in the adolescent. Accurate diagnosis is important given the long-term implications of the disorder, with increasing emphasis on metabolic sequelae. Copyright © 2013 Elsevier Inc. All rights reserved.

Treatable newborn and infant seizures due to inborn errors of metabolism.

Campistol, Jaume; Plecko, Barbara

2015-09-01

About 25% of seizures in the neonatal period have causes other than asphyxia, ischaemia or intracranial bleeding. Among these are primary genetic epileptic encephalopathies with sometimes poor prognosis and high mortality. In addition, some forms of neonatal infant seizures are due to inborn errors of metabolism that do not respond to common AEDs, but are amenable to specific treatment. In this situation, early recognition can allow seizure control and will prevent neurological deterioration and long-term sequelae. We review the group of inborn errors of metabolism that lead to newborn/infant seizures and epilepsy, of which the treatment with cofactors is very different to that used in typical epilepsy management.

[Cutaneous and systemic toxicology of vesicants used in warfare].

PubMed

Pita, R; Vidal-Asensi, S

2010-01-01

Vesicants are a group of chemicals used in warfare. The most representative agent is yperite, also known as mustard gas. The blisters that appeared on those exposed to yperite during combat in the First World War are responsible for the current name--vesicants--for this group of chemicals. Their affects are produced mainly through localized action of liquid or vapor forms on the skin, eyes, and respiratory tract. However, the high absorption of the liquid form through the skin or the vapor form on inhalation may cause substantial systemic effects. Here we analyze these effects, treatment of intoxication, and long-term sequelae, drawing on our experience and a review of the literature.

The Maternal Gut Microbiome During Pregnancy.

PubMed

Edwards, Sara M; Cunningham, Solveig A; Dunlop, Anne L; Corwin, Elizabeth J

The gut microbiome is a critical component of an individual's metabolism and overall health. The prenatal period is marked by unique inflammatory and immune changes that alter maternal gut function and bacterial composition as the pregnancy advances. The composition of the maternal gut microbiome contributes to obstetric outcomes with long-term health sequelae for mother and child. Estrogen and progesterone also have an impact on gut function, especially during the prenatal period. These physiologic changes in pregnancy allow for adjustments in maternal metabolism and weight necessary to support the pregnancy. Normal hormonal, metabolic, and immunologic changes to the maternal gut microbiome throughout the prenatal period are reviewed, including relevant implications for nurses providing care for pregnant women.

Although infant attachment has been long seen as key for development, its long-term effects may be complex. Attachment may be a catalyst or moderator of future developmental sequelae rather than a source of main effects. In 102 mothers, fathers, and infants, attachment was assessed at 15 months; children's negativity (rejection of parental rules and modeling attempts) at 25, 38, 52, and 67 months; and developmental outcomes (the child's parent-rated externalizing problems and the parent-child observed relationship quality) at ages 10 and 12. In both mother-child and father-child relationships, children's higher negativity was associated with more detrimental outcomes but only in dyads with formerly insecure infants. Infant insecurity appears to amplify detrimental cascades, whereas infant security appears to defuse such risks. © 2016 The Authors.

To investigate the relation between low Apgar score in breech infants and handicap in childhood. A case-control study. A questionnaire to mothers of 323 non-malformed, singleton infants delivered in breech presentation at term, 105 cases with Apgar score below 7 at 5 min and 218 controls. Four cases (4.6%) and one control (0.5%) had cerebral palsy. In infants without cerebral palsy, speech/language problems were more frequent than controls (10.6 versus 3.2%) (P=0.02). There were no differences in rates of deficits in attention, motor control and perception (DAMP), epilepsy, cognitive developmental delay or learning disabilities. Absence of any handicap or disability was reported in 65 cases (75%) compared to 172 controls (92%) (OR: 3.9; 95% CI: 1.9-7.9). Even though low Apgar score indicates an increased risk of neurological sequelae, most (75%) breech infants with low Apgar score are without a handicap/disability at follow-up.

Abstract Although increasingly frequent, little is known about the clinical presentation, radiological signs, and outcome of Candida vertebral osteomyelitis (CVO). We performed a nationwide retrospective study of laboratory-confirmed cases of CVO over a 10 year-period in France with a prolonged follow-up. We describe demographic, clinical, biological, and radiological characteristics of patients with CVO, patients’ management, and long-term outcome and determine factors associated with a poor outcome. In total, 28 patients with laboratory-confirmed CVO were included. A prior systemic Candida infection was evidenced in 13/28 (46%), occurring a median of 6 weeks before CVO was diagnosed. Twenty-six of 28 (93%) had at least 1 underlying condition at risk of invasive fungal disease, and in 19/28 (68%) CVO was health-care related. C albicans was most frequently identified (21/28; 75%) Lumbo-sacral involvement was the most prevalent (20/28—71%). Nearly half patients had no fever at presentation, but all had pain. Initial antifungal therapy consisted in fluconazole in 15/28 (53%); surgery was needed in 5 (18%) cases. One-year mortality was 21% (6/28), directly related to fungal infection in 2 patients. Risk-factors associated with 1-year mortality were age (P=.02), a high Charlson comorbidity index (P = .001), and a shorter treatment duration (median, 3 months vs 6 months; P = .02). Among 22 patients who survived, the median follow up duration was 15.5 months (8–93.5); 10 had sequelae, consisting in pain in all and neurological deficit in one. A longer treatment duration was significantly associated with healing without sequelae (P = .04). CVO concerns patients with serious underlying conditions and risk-factors for invasive candidiasis. Prolonged antifungal treatment appears to improve survival without sequelae. PMID:28767571

Nontyphoidal Salmonella spp. are one of the most common causes of bacterial foodborne illness. Variability in cost inventories and study methodologies limits the possibility of meaningfully interpreting and comparing cost-of-illness (COI) estimates, reducing their usefulness. However, little is known about the relative effect these factors have on a cost-of-illness estimate. This is important for comparing existing estimates and when designing new cost-of-illness studies. Cost-of-illness estimates, identified through a scoping review, were used to investigate the association between descriptive, component cost, methodological, and foodborne illness-related factors such as chronic sequelae and under-reporting with the cost of nontyphoidal Salmonella spp. illness. The standardized cost of nontyphoidal Salmonella spp. illness from 30 estimates reported in 29 studies ranged from $0.01568 to $41.22 United States dollars (USD)/person/year (2012). The mean cost of nontyphoidal Salmonella spp. illness was $10.37 USD/person/year (2012). The following factors were found to be significant in multiple linear regression (p≤0.05): the number of direct component cost categories included in an estimate (0-4, particularly long-term care costs) and chronic sequelae costs (inclusion/exclusion), which had positive associations with the cost of nontyphoidal Salmonella spp. illness. Factors related to study methodology were not significant. Our findings indicated that study methodology may not be as influential as other factors, such as the number of direct component cost categories included in an estimate and costs incurred due to chronic sequelae. Therefore, these may be the most important factors to consider when designing, interpreting, and comparing cost of foodborne illness studies.

Dilatational tracheotomy techniques are widely used in the long-term management of the respiratory tract in patients in intensive care units (ICU). The translaryngeal tracheotomy technique (TLT) was first described by Fantoni in 1993 and rapidly asserted itself, especially in Europe. This technique basically differs from the other percutaneous techniques in that it involves a progressive, retrograde, dilatation of the trachea in a single session conducted from inside the trachea, working outward, simultaneously exerting a counter-pressure on the pre-tracheal soft tissues with the fingers. The present study involves an endoscopy follow-up of 130 patients who had undergone TLT at the Intensive Care Unit of our Hospital between November 2000 and May 2001. The pre-operative oro-tracheal intubation time varied from 1 to 42 days. All patients filled out a brief questionnaire containing validated questions on their general health and quality of life with particular attention focused on respiratory conditions. Then, after receiving informed consent, the patients underwent laryngo-tracheoscopy with local anesthetic using a flexible tracheobronchoscope. All tests were recorded and viewed later by two operators in order to identify and divide the patients according to the level of execution of the tracheotomy and the presence of sequelae. The results obtained have shown that, like other percutaneous tracheotomy techniques, TLT provides some benefits including the fact that procedure can be performed at the bedside in a short time, with few post-operative complications, simpler nursing and fewer sequelae in time. Analysis of data concerning time of tracheostomy execution, tracheal level of stomia and nursing times has revealed three factors that determine severe sequelae: delay in tracheostomy execution, high level of execution with cricoid involvement and onset of problems during first tracheal cannula change.

OBJECTIVE The purpose of this study was to report the frequency of abnormal cystoscopy at incontinence surgery and to identify risk factors and sequelae of injury. STUDY DESIGN Findings of cystoscopy were collected prospectively in 3 multicenter surgical trials. Clinical, demographic, and procedure characteristics and surgeon experience were analyzed for association with iatrogenic injury and noninjury abnormalities. Impact of abnormalities on continence outcomes and adverse events during 12 months after the procedure were assessed. RESULTS Abnormal findings in the bladder or urethra were identified in 95 of 1830 women (5.2%). Most injuries (75.8%) were iatrogenic. Lower urinary tract (LUT) injury was most common at retropubic urethropexy and retropubic midurethral sling procedures (MUS; 6.4% each), followed by autologous pubovaginal sling procedures (1.7%) and transobturator MUS (0.4%). Increasing age (56.9 vs 51.9 years; P = .04), vaginal deliveries (3.2 vs 2.6; P = .04), and blood loss (393 vs 218 mL; P=.01) were associated with LUT injury during retropubic urethropexy; however, only age (62.9 vs 51.4 years; P = .02) and smoking history (P = .04) were associated for pubovaginal sling procedures. No factors correlated with increased risk of injury at retropubic and transobturator MUS. Notably, previous incontinence surgery, concomitant procedures, anesthesia type, and trainee participation did not increase LUT injury frequency. Although discharge with an indwelling catheter was more common after trocar perforation compared with the noninjury group (55.6% vs 18.5%; P < .001), they did not differ in overall success, voiding dysfunction, recurrent urinary tract infections, or urge urinary incontinence. CONCLUSION Universal cystoscopy at incontinence surgery detects abnormalities in 1 in 20 women. Urinary trocar perforations that are addressed intraoperatively have no long-term adverse sequelae.

Immunity and inflammation in status epilepticus and its sequelae: possibilities for therapeutic application

PubMed Central

Vezzani, Annamaria; Dingledine, Raymond; Rossetti, Andrea O

2016-01-01

Status epilepticus (SE) is a life-threatening neurological emergency often refractory to available treatment options. It is a very heterogeneous condition in terms of clinical presentation and causes, which besides genetic, vascular and other structural causes also include CNS or severe systemic infections, sudden withdrawal from benzodiazepines or anticonvulsants and rare autoimmune etiologies. Treatment of SE is essentially based on expert opinions and antiepileptic drug treatment per se seems to have no major impact on prognosis. There is, therefore, urgent need of novel therapies that rely upon a better understanding of the basic mechanisms underlying this clinical condition. Accumulating evidence in animal models highlights that inflammation ensuing in the brain during SE may play a determinant role in ongoing seizures and their long-term detrimental consequences, independent of an infection or auto-immune cause; this evidence encourages reconsideration of the treatment flow in SE patients.

Pathophysiology of Sleep Apnea

2010-01-01

Sleep-induced apnea and disordered breathing refers to intermittent, cyclical cessations or reductions of airflow, with or without obstructions of the upper airway (OSA). In the presence of an anatomically compromised, collapsible airway, the sleep-induced loss of compensatory tonic input to the upper airway dilator muscle motor neurons leads to collapse of the pharyngeal airway. In turn, the ability of the sleeping subject to compensate for this airway obstruction will determine the degree of cycling of these events. Several of the classic neurotransmitters and a growing list of neuromodulators have now been identified that contribute to neurochemical regulation of pharyngeal motor neuron activity and airway patency. Limited progress has been made in developing pharmacotherapies with acceptable specificity for the treatment of sleep-induced airway obstruction. We review three types of major long-term sequelae to severe OSA that have been assessed in humans through use of continuous positive airway pressure (CPAP) treatment and in animal models via long-term intermittent hypoxemia (IH): 1) cardiovascular. The evidence is strongest to support daytime systemic hypertension as a consequence of severe OSA, with less conclusive effects on pulmonary hypertension, stroke, coronary artery disease, and cardiac arrhythmias. The underlying mechanisms mediating hypertension include enhanced chemoreceptor sensitivity causing excessive daytime sympathetic vasoconstrictor activity, combined with overproduction of superoxide ion and inflammatory effects on resistance vessels. 2) Insulin sensitivity and homeostasis of glucose regulation are negatively impacted by both intermittent hypoxemia and sleep disruption, but whether these influences of OSA are sufficient, independent of obesity, to contribute significantly to the “metabolic syndrome” remains unsettled. 3) Neurocognitive effects include daytime sleepiness and impaired memory and concentration. These effects reflect hypoxic-induced “neural injury.” We discuss future research into understanding the pathophysiology of sleep apnea as a basis for uncovering newer forms of treatment of both the ventilatory disorder and its multiple sequelae.

Purpose The incidence of conjunctival malignancies is less than 1%. Though surgical excision remains the mainstay of treatment, the incidence of positive surgical margins and local recurrence rates are high, which is approximately up to 33% in negative margins and 56% in positive margins. Radiotherapy reduces the risk of recurrence in these cases. Brachytherapy using β emitters such as strontium-90 (90Sr) is an ideal treatment technique for these tumors with the advantage of treating only a few millimeters of tissue while sparing the underlying normal eye. We report the long term outcomes in the form of local control and late sequelae of patients with conjunctival malignancies treated with 90Sr applicator brachytherapy. Material and methods During 1999-2013, 13 patients with conjunctival tumors, treated using 90Sr brachytherapy were analyzed. Brachytherapy was either in a post-operative adjuvant or in a recurrent setting. Local control (LC), disease free survival (DFS), overall survival (OS), and late sequelae were evaluated. Results The median age at presentation was 47 years (range: 11-71 years). Thirteen patients with 15 tumors were treated. The commonest histology was squamous cell carcinoma. The median dose was 44 Gy over 11 fractions. The median follow up of all the patients was 51 months (range: 3-139 months). The median follow up of patients with carcinoma only was 64 months with a LC and DFS of 90.9% at 5 years. None of the patients developed ≥ grade II Radiation Therapy Oncology Group (RTOG) acute toxicities. One patient developed a focal scar and another developed corneal opacification at the limbus. Vision was not impaired in any of the patients. Conclusions Strontium-90 brachytherapy used in early invasive conjunctival malignancies as an adjunct to surgery in primary and recurrent settings, results in optimal disease control and ocular functional outcomes.

Stressful life events in childhood during critical periods of development have long-term psychological and neurobiological sequelae, which may affect risk for HIV infection across the life course. Data were from a nationally representative sample of 13,274 US men (National Epidemiologic Survey on Alcohol and Related Conditions, 2004-2005). Weighted multivariable logistic regression models examined (1) the association of childhood violent events before age 18 on 12-month incident HIV infection and (2) whether posttraumatic stress disorder (PTSD) diagnosis (clinical interview) mediated the association between early life events and HIV. Overall, the 12-month HIV incidence was <1% (0.35%); 44% of new infections were among racial/ethnic minorities and 31% among men who have sex with men). One-third of the sample (33.5%) reported one or more early life stressors (physical abuse, sexual abuse, neglect, verbal violence, or witnessed violence). In a weighted multivariable logistic regression model adjusted for age, education, family's socioeconomic position, and sexual behaviors, each additional early life violent event was associated with an elevated odds of HIV infection [adjusted odds ratio (aOR) = 1.32; 95% confidence interval (CI): 1.16 to 1.50]. Adding PTSD to this adjusted model, PTSD was highly associated with incident HIV infection (aOR = 5.75; 95% CI: 4.76 to 6.95). There was evidence that PTSD partially mediated the relationship between early life events and HIV (aOR = 1.14; 95% CI: 1.02 to 1.28). Experiencing early life violent family stressors was associated with HIV infection among men. Early life events and HIV infection were mediated by PTSD, which has implications for understanding disparities in HIV infection. Interventions are urgently needed that address the long-term sequelae of childhood violence.

In the USA, 450,000 thermal burns receive medical treatment annually. Burn scars are commonly excised and covered with skin grafts. Long-term, these treatments commonly leave patients with discomfort, reduced total lung capacity and forced vital capacity, and restriction of thoracic expansion and shoulder joint mobility. In this article, we present our experience with using scar release and immediate flap reconstruction to treat thoracic restriction due to burn sequelae. From 1998 to 2014, we enrolled 16 patients with anterior thoracic burn sequelae that had previously been treated conservatively or with skin grafts that eventually recidivated. Preoperatively, we measured thoracic circumference in expiration and inspiration, %FVC, %FEV1, and shoulder mobility. All patients underwent anterior thoracic scar release and immediate flap resurfacing. At 2 weeks to 3 months postoperatively (mean, 2.6 months), mean thoracic circumference upon inspiration increased from 83.6 cm±5.7 to 86.5 cm±5.8 (p<0.0000000001). Mean %FVC improved from 76.0%±2.64% to 88.2%±4.69% (p<0.0000001). Mean %FEV1 improved from 79.2%±3.85 to 87.8%±2.98 (p<0.000001). All 14 patients who had restricted shoulder mobility preoperatively no longer had restricted shoulder mobility postoperatively. The mean patient-reported satisfaction was 4.6/5 (range, 3-5). At a mean follow up of 2.5 years, none of the contractures recidivated. Complications included 2 cases of tissue necrosis of the distal end of the flap. In one case, the flap was restored; in the other case, the patient eventually had to receive a new flap. Additional complications included two local infections that were successfully treated with oral and local antibiotics and two hematomas that were drained and eventually healed without tissue loss. Scar releases and flaps provide a safe and effective method for the correction of restricted thoracic expansion, respiratory restriction, decreased range of shoulder motion, and discomfort from thoracic burn sequelae.

Voltage has historically guided the acute management and long-term prognosis of physical morbidity in electrical injury patients; however, few large studies exist that include neuropsychiatric morbidity in final outcome analysis. This review compares high (>1000 V) to low (<1000 V) voltage injuries, focusing on return to work and neuropsychiatric sequelae following electrical burn injury. Patients with electrical injuries admitted to the University of North Carolina Jaycee Burn Center between 2000 and 2005 were prospectively entered into a trauma database, then retrospectively reviewed. Patients were divided into 4 cohorts: high voltage (>1000 V), low voltage (<1000 V), flash arc, and lightning. Demographics, hospital course, and follow-up were recorded to determine physical and neuropsychiatric morbidity. Differences among cohorts were tested for statistical significance. Over 5 years, 2548 patients were admitted to the burn center, including 115 patients with electrical injuries. There were 110 males and 5 females, with a mean age of 35 years (range, 0.75-65 years). The cause of the electrical injury was high voltage in 60 cases, low voltage in 25 cases, flash arc in 29 cases and lightning in 1 case. The mean total body surface area burn was 8% (range, 0%-52%). The etiology was work-related electrical injury in 85 patients. Mean follow-up period was 352 days with 13 (11%) patients lost to follow-up. Patients with high voltage injuries had significantly larger total body surface area burn, longer ICU stays, longer hospitalizations, and significantly higher rates of fasciotomy, amputation, nerve decompression and outpatient reconstruction, with 4 cases of renal failure and 2 deaths. In spite of these differences, high and low voltage groups experienced similar rates of neuropsychiatric sequelae, limited return to work and delays in return to work. Final impairment ratings for the high and low voltage groups were 17.5% and 5.3%, respectively. Electrical injuries often incur severe morbidity despite relatively small burn size and/or low voltage. When comparing high and low voltage injuries, similarities in endpoints such as neuropsychiatric sequelae, the need for late reconstruction, and failure to return to work challenge previous notions that voltage predicts outcome.

As NASA prepares for the first manned spaceflight to Mars, questions have surfaced concerning the potential for increased risks associated with exposure to the spectrum of highly energetic nuclei that comprise galactic cosmic rays. Animal models have revealed an unexpected sensitivity of mature neurons in the brain to charged particles found in space. Astronaut autonomy during long-term space travel is particularly critical as is the need to properly manage planned and unanticipated events, activities that could be compromised by accumulating particle traversals through the brain. Using mice subjected to space-relevant fluences of charged particles, we show significant cortical- and hippocampal-based performance decrements 6 weeks after acute exposure. Animals manifesting cognitive decrements exhibited marked and persistent radiation-induced reductions in dendritic complexity and spine density along medial prefrontal cortical neurons known to mediate neurotransmission specifically interrogated by our behavioral tasks. Significant increases in postsynaptic density protein 95 (PSD-95) revealed major radiation-induced alterations in synaptic integrity. Impaired behavioral performance of individual animals correlated significantly with reduced spine density and trended with increased synaptic puncta, thereby providing quantitative measures of risk for developing cognitive decrements. Our data indicate an unexpected and unique susceptibility of the central nervous system to space radiation exposure, and argue that the underlying radiation sensitivity of delicate neuronal structure may well predispose astronauts to unintended mission-critical performance decrements and/or longer-term neurocognitive sequelae.

The aim of the study was to compare the long-term effects of conflict-related sexual violence experienced at the end of World War II (WWII) with non-sexual WWII trauma (e.g., being exposed to shell shock or physical violence). A total of 27 elderly wartime rape survivors were compared to age- and gender-matched control subjects who were drawn from a larger sample of subjects over 70 years of age who had experienced WWII-related trauma. A modified version of the Posttraumatic Diagnostic Scale was used to assess trauma characteristics and posttraumatic stress disorder (PTSD) symptoms and the Brief Symptom Inventory-18 was used to assess current psychopathology. Additionally, measures of posttraumatic growth (Posttraumatic Growth Inventory) and social acknowledgement as a trauma survivor (Social Acknowledgement Questionnaire) were used to assess two mediating variables in post-trauma conditions of rape victims. Women exposed to conflict-related sexual violence reported greater severity of PTSD-related avoidance and hyperarousal symptoms, as well as anxiety, compared with female long-term survivors of non-sexual WWII trauma. The vast majority (80.9 %) of these women also reported severe sexual problems during their lifetimes relative to 19.0 % of women who experienced non-sexual war trauma. Women exposed to conflict-related sexual violence also reported greater posttraumatic growth, but less social acknowledgement as trauma survivors, compared to survivors of non-sexual war trauma. The results were consistent with emerging neurobiological research, which suggests that different traumas may be differentially associated with long-term posttraumatic sequelae in sexual assault survivors than in other survivor groups and highlights the need to treat (or better prevent) deleterious effects of conflict-related sexual violence in current worldwide crisis zones.

Supportive care after curative treatment for breast cancer (survivorship care): resource allocations in low- and middle-income countries. A Breast Health Global Initiative 2013 consensus statement.

Breast cancer survivors may experience long-term treatment complications, must live with the risk of cancer recurrence, and often experience psychosocial complications that require supportive care services. In low- and middle-income settings, supportive care services are frequently limited, and program development for survivorship care and long-term follow-up has not been well addressed. As part of the 5th Breast Health Global Initiative (BHGI) Global Summit, an expert panel identified nine key resources recommended for appropriate survivorship care, and developed resource-stratified recommendations to illustrate how health systems can provide supportive care services for breast cancer survivors after curative treatment, using available resources. Key recommendations include health professional education that focuses on the management of physical and psychosocial long-term treatment complications. Patient education can help survivors transition from a provider-intense cancer treatment program to a post-treatment provider partnership and self-management program, and should include: education on recognizing disease recurrence or metastases; management of treatment-related sequelae, and psychosocial complications; and the importance of maintaining a healthy lifestyle. Increasing community awareness of survivorship issues was also identified as an important part of supportive care programs. Other recommendations include screening and management of psychosocial distress; management of long-term treatment-related complications including lymphedema, fatigue, insomnia, pain, and women's health issues; and monitoring survivors for recurrences or development of second primary malignancies. Where possible, breast cancer survivors should implement healthy lifestyle modifications, including physical activity, and maintain a healthy weight. Health professionals should provide well-documented patient care records that can follow a patient as they transition from active treatment to follow-up care. Copyright © 2013 The Authors.

Heart rate variability (HRV) has emerged as a predictor of later cardiac risk. This study tested whether pregnancy complications that may have long-term offspring cardiac sequelae are associated with differences in HRV at birth, and whether these HRV differences identify abnormal cardiovascular development in the postnatal period. Ninety-eight sleeping neonates had 5-min electrocardiogram recordings at birth. Standard time and frequency domain parameters were calculated and related to cardiovascular measures at birth and 3 months of age. Increasing prematurity, but not maternal hypertension or growth restriction, was associated with decreased HRV at birth, as demonstrated by a lower root mean square of the difference between adjacent NN intervals (rMSSD) and low (LF) and high-frequency power (HF), with decreasing gestational age (p < 0.001, p = 0.009 and p = 0.007, respectively). We also demonstrated a relative imbalance between sympathetic and parasympathetic tone, compared to the term infants. However, differences in autonomic function did not predict cardiovascular measures at either time point. Altered cardiac autonomic function at birth relates to prematurity rather than other pregnancy complications and does not predict cardiovascular developmental patterns during the first 3 months post birth. Long-term studies will be needed to understand the relevance to cardiovascular risk.

Incomplete recovery of facial motor function continues to be long-term sequelae in some patients with Bell's palsy. The purpose of this study was to investigate the efficacy of transmastoid facial nerve decompression after steroid and antiviral treatment in patients with late stage Bell's palsy. Twelve patients underwent surgical decompression for Bell's palsy 21-70 days after onset, whereas 22 patients were followed up after steroid and antiviral therapy without decompression. Surgical criteria included greater than 90 % degeneration on electroneuronography and no voluntary electromyography potentials. This study was a retrospective study of electrodiagnostic data and medical chart review between 2006 and 2013. Recovery from facial palsy was assessed using the House-Brackmann grading system. Final recovery rate did not differ significantly in the two groups; however, all patients in the decompression group recovered to at least House-Brackmann grade III at final follow-up. Although postoperative hearing threshold was increased in both groups, there was no significant between group difference in hearing threshold. Transmastoid decompression of the facial nerve in patients with severe late stage Bell's palsy at risk for a poor facial nerve outcome reduced severe complications of facial palsy with minimal morbidity.

Traumatic brain injury (TBI) sustained during childhood can affect a number of socio-cognitive skills; however, little attention has focused on the integrity of moral reasoning in the assessment of post-TBI social sequelae and the role of empathy and intelligence on moral maturity. In a quasi-experimental, cross-sectional research design, moral reasoning maturity and empathy in adolescents with mild-to-severe TBI (n = 25) were compared to typically-developing peers (n = 66). Participants were administered the So-Moral and So-Mature, tasks of socio-moral reasoning and maturity, the Index of Empathy for Children and Adolescents, the Wechsler Abbreviated Scale of Intelligence and a demographic questionnaire. Participants with TBI had significantly lower levels of moral reasoning maturity. Further, adolescents with moderate-to-severe TBI had lower levels of empathy. Empathy correlated positively with moral reasoning abilities and, together with intellectual function, predicted a small, but significant proportion of moral reasoning outcome. Youth who sustained TBI during childhood have poorer moral reasoning abilities than their non-injured peers, potentially placing them at risk for poor social decision-making and socially maladaptive behaviour. This can have a significant impact on long-term social functioning.

Overcoming immune tolerance in chronic hepatitis B by therapeutic vaccination.

2018-05-08

The currently used nucleoside analogs (i.e. entecavir and tenofovir) with high barrier-to-resistance efficiently suppress viral replication, limit inflammation and reduce the sequelae of chronic hepatitis B, but cannot cure the disease and thus have to be applied long-term. Therapeutic vaccination as an approach to cure chronic hepatitis B has shown promising pre-clinical results, nevertheless the proof of its efficacy in clinical trials is still missing. This may be partially due to suboptimal vaccine design. A main obstacle in chronic hepatitis B, however, is the high load of viral antigens expressed and secreted, which has been proposed to cause antigen-specific immune tolerance. Reduction of the viral antigen load is therefore considered a key factor for success of immune-based therapies. Although nucleoside analogs do not reduce viral antigen expression, new antiviral strategies are becoming available. Targeting viral translation by siRNA or targeting release of HBsAg from infected hepatocytes by nucleic acid polymers both reduce the antigen load. They may be considered as pre-treatment for therapeutic vaccination to increase the potential to elicit an HBV-specific immune response able to control and cure chronic HBV infection.

[Pulmonary thromboendarterectomy].

Chronic thromboembolic pulmonary hypertension with concomitant right heart failure may develop as a sequela of acute pulmonary embolism with organization instead of thrombolysis of intravascular clots. Medical therapy aims at prevention of recurrent embolism by anticoagulation and vascular remodelling using vasodilator therapy. Lung transplantation or combined heart-lung transplantation is associated with unsatisfactory long-term results and comorbidity and therefore remains justified only in selected patients. Pulmonary thromboendarterectomy allows specific treatment of intravascular obstruction. This closed endarterectomy of the pulmonary arteries requires deep hypothermic circulatory arrest and can be performed with a perioperative mortality of less than 10%. The procedure significantly decreases pulmonary vascular resistance and often normalizes pulmonary hemodynamics and gas exchange. Postoperatively the patients' clinical condition improves and the majority have normal exercise capacity and activity.

Transcatheter aortic valve replacement can be an effective, reliable treatment for severe aortic stenosis in surgically high-risk or ineligible patients. However, various sequelae like coronary artery obstruction can occur, not only in the long term, but also immediately after the procedure. We present the case of a 78-year-old woman whose left main coronary artery became obstructed with calculus 2 hours after the transfemoral implantation of an Edwards Sapien XT aortic valve. Despite percutaneous coronary intervention in that artery, the patient died. This case reminds us that early recognition of acute coronary obstruction and prompt intervention are crucial in patients with aortic stenosis who have undergone transcatheter aortic valve replacement.

Prevalence, characteristics, and long-term sequelae of natural disaster exposure in the general population.

PubMed

Briere, J; Elliott, D

2000-10-01

A sample of 935 participants from the general population completed a mail-out questionnaire containing the Trauma Symptom Inventory (J. Briere, 1995) and the Traumatic Events Survey (D. M. Elliott, 1992). The lifetime self-reported prevalence of natural disasters in this sample was 22%. Although time from the last disaster to involvement in the study was an average of 13 years, previous disaster was associated with significantly higher scores on 6 of 10 symptom scales. Disaster characteristics (especially the presence of physical injury, fear of death, and property loss) were better predictors of symptomatology than was disaster type. Disaster exposure continued to predict symptomatology after controlling for interpersonal violence history, although interpersonal violence accounted for more overall symptom variance.

The Arm is Not the Leg: Pathophysiology, Diagnosis, and Management of Upper Extremity Deep Vein Thrombosis.

Upper extremity deep venous thrombosis (UEDVT) involves thrombosis of the deep veins of the arm as they enter the thorax. They are increasing in frequency, largely due to the rising use of central venous catheters and implantable cardiac devices, and represent more than 10% of all DVT cases, Upper extremity deep venous thrombosis has been historically misunderstood when compared to lower extremity deep vein thrombosis (LEDVT). Their associated disease states may carry devastating complications, with mortality rates often higher than that of LEDVT. Thus, education on recognition, classification and management is critical to avoid long-term sequelae and mortality from UEDVT.

Several symptoms associated with chronic pain, including fatigue and depression, are characterized by reduced motivation to initiate or complete goal-directed tasks. However, it is unknown whether maladaptive modifications in neural circuits that regulate motivation occur during chronic pain. Here, we demonstrate that the decreased motivation elicited in mice by two different models of chronic pain requires a galanin receptor 1-triggered depression of excitatory synaptic transmission in indirect pathway nucleus accumbens medium spiny neurons. These results demonstrate a previously unknown pathological adaption in a key node of motivational neural circuitry that is required for one of the major sequela of chronic pain states and syndromes.

Stroke is becoming more common in Germany as the population ages. Its long-term sequelae can be alleviated by early reperfusion in stroke units and by complication management and functional restoration in early-rehabilitation and rehabilitation centers. Selective review of the literature. Successful rehabilitation depends on systematic treatment by an interdisciplinary team of experienced specialists. In the area of functional restoration, there has been major progress in our understanding of the physiology of learning, relearning, training, and neuroenhancement. There have also been advances in supportive pharmacotherapy and robot technology. Well-organized acute and intermediate rehabilitation after stroke can provide patients with the best functional results attainable on the basis of our current scientific understanding. Further experimental and clinical studies will be needed to expand our knowledge and improve the efficacy of rehabilitation.

Traumatic brain injury and delayed sequelae: a review--traumatic brain injury and mild traumatic brain injury (concussion) are precursors to later-onset brain disorders, including early-onset dementia.

Brain injuries are too common. Most people are unaware of the incidence of and horrendous consequences of traumatic brain injury (TBI) and mild traumatic brain injury (MTBI). Research and the advent of sophisticated imaging have led to progression in the understanding of brain pathophysiology following TBI. Seminal evidence from animal and human experiments demonstrate links between TBI and the subsequent onset of premature, psychiatric syndromes and neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD). Objectives of this summary are, therefore, to instill appreciation regarding the importance of brain injury prevention, diagnosis, and treatment, and to increase awareness regarding the long-term delayed consequences following TBI.

Long-term cannabis use may confer cognitive deficits and increased risk of psychosis. However, the relationship between cannabis use and schizophrenia is complex. In particular, little is known about the effects of chronic cannabis use on the attention-related electric brain response in schizophrenia. We investigated auditory novelty and oddball P300 evoked potentials in a mixed sample of first-episode and chronic schizophrenic patients and healthy controls with (SZCA, n = 20; COCA, n = 20, abstinence ≥28 days) or without (SZ, n = 20; CO, n = 20) chronic cannabis use. Duration of regular cannabis use was 8.3 ± 5.6 (SZCA) and 9.1 ± 7.1 (COCA) years. In general, schizophrenic patients showed reduced P300 amplitudes. Cannabis use was associated with both a reduced early and late left-hemispheric novelty P300. There was a significant 'diagnosis × cannabis' interaction for the left-hemispheric late novelty P300 in that cannabis use was associated with a reduced amplitude in the otherwise healthy but not in the schizophrenic group compared with their relative control groups (corrected p < 0.02; p > 0.9, respectively). The left-hemispheric late novelty P300 in the otherwise healthy cannabis group correlated inversely with amount and duration of cannabis use (r = -0.50, p = 0.024; r = -0.57, p = 0.009, respectively). Our study confirms attentional deficits with chronic cannabis use. However, cannabis use may lead to different cognitive sequelae in patients with schizophrenia and in healthy controls, possibly reflecting preexisting alterations in the endocannabinoid system in schizophrenia.

Long-term consequences of the posterior reversible encephalopathy syndrome in eclampsia and preeclampsia: a review of the obstetric and nonobstetric literature.

This review summarizes the long-term consequences of the posterior reversible encephalopathy syndrome (PRES) that have been described in the obstetric literature (eclampsia and preeclampsia) and compares these with data from the nonobstetric literature. Preeclampsia is characterized by new-onset hypertension and proteinuria after the 20th week of pregnancy. Neurological symptoms include headache; visual deficits; confusion; seizures; and, in the most severe cases, intracranial hemorrhage. Eclampsia is an acute cerebral complication of preeclampsia, defined as the occurrence of tonic-clonic seizures in pregnant or recently postpartum women. With severe preeclampsia, in conjunction with neurological symptoms, or eclampsia, neuroimaging changes consistent with PRES can be seen. Posterior reversible encephalopathy syndrome is a specific clinicoradiological syndrome presenting with headaches, visual impairment, seizures, and altered mental status. Characteristic neuroimaging features are consistent with cerebral edema predominantly in the parietal and occipital lobes. In addition to preeclampsia/eclampsia, PRES has been associated with various conditions in the nonobstetric population, that is, severe hypertension, transplantation, or autoimmune disease, in combination with immunosuppressive therapy or high-dose chemotherapy for various malignant conditions. Long-term sequelae of both preeclampsia/eclampsia and other PRES-related conditions are poorly described. After eclampsia or preeclampsia, nonspecific white matter lesions may be found on magnetic resonance imaging, which may or may not be related to the PRES episode. Previously (pre)eclamptic women report cognitive failures; however, no neurocognitive impairment has been shown so far. Various nonobstetric PRES-related conditions have been described with long-term neuroimaging abnormalities as well as cognitive problems, epilepsy, or visual impairment. Although no firm conclusions can be drawn because of the heterogeneity of reported cases, some general comments can be made. Because most persistent long-term problems are present in the nonobstetric population, the main determinant for these long-term problems may be the underlying condition that gave rise to the PRES episode. In addition, most reports suggest that late diagnosis or inadequate therapy may contribute, emphasizing the need for early recognition, adequate treatment, follow-up, and support.

The consequences of Campylobacter infection.

O'Brien, Sarah J

2017-01-01

The purpose of this review is to provide an update on the clinical, public health and economic consequences of Campylobacter infection. Campylobacter is a leading bacterial cause of food-related illness. Its importance is enhanced by the chronic sequelae that can result from acute infection. Recent advances include a new clinical classification system for neurological sequelae with the aim of speeding accurate diagnosis and appropriate treatment, a better understanding of the mechanisms underlying postinfectious functional gastrointestinal disorders, the emergence of Campylobacter concisus and Campylobacter showae as potential aetiological agents in inflammatory bowel disease, a new mechanism for antimicrobial resistance in campylobacters and a better appreciation of the economic costs. Campylobacter infection is very common and can lead to serious chronic sequelae and considerable personal, healthcare and societal costs.

Cleveland Clinic intelligent mouthguard: a new technology to accurately measure head impact in athletes and soldiers

2013-05-01

Nearly 2 million Traumatic Brain Injuries (TBI) occur in the U.S. each year, with societal costs approaching $60 billion. Including mild TBI and concussion, TBI's are prevalent in soldiers returning from Iraq and Afghanistan as well as in domestic athletes. Long-term risks of single and cumulative head impact dosage may present in the form of post traumatic stress disorder (PTSD), depression, suicide, Chronic Traumatic Encephalopathy (CTE), dementia, Alzheimer's and Parkinson's diseases. Quantifying head impact dosage and understanding associated risk factors for the development of long-term sequelae is critical toward developing guidelines for TBI exposure and post-exposure management. The current knowledge gap between head impact exposure and clinical outcomes limits the understanding of underlying TBI mechanisms, including effective treatment protocols and prevention methods for soldiers and athletes. In order to begin addressing this knowledge gap, Cleveland Clinic is developing the "Intelligent Mouthguard" head impact dosimeter. Current testing indicates the Intelligent Mouthguard can quantify linear acceleration with 3% error and angular acceleration with 17% error during impacts ranging from 10g to 174g and 850rad/s2 to 10000rad/s2, respectively. Correlation was high (R2 > 0.99, R2 = 0.98, respectively). Near-term development will be geared towards quantifying head impact dosages in vitro, longitudinally in athletes and to test new sensors for possible improved accuracy and reduced bias. Long-term, the IMG may be useful to soldiers to be paired with neurocognitive clinical data quantifying resultant TBI functional deficits.

Are there any potentially dangerous pharmacological effects of combining ADHD medication with alcohol and drugs of abuse? A systematic review of the literature.

Among young people up to 18 years of age, approximately 5% have attention deficit hyperactivity disorder (ADHD), many of whom have symptoms persisting into adulthood. ADHD is associated with increased risk of co-morbid psychiatric disorders, including substance misuse. Many will be prescribed medication, namely methylphenidate, atomoxetine, dexamphetamine and lisdexamfetamine. If so, it is important to know if interactions exist and if they are potentially toxic. Three databases (Medline, EMBASE and PsychINFO) from a 22 year period (1992 - June 2014) were searched systematically. Key search terms included alcohol, substance related disorders, methylphenidate, atomoxetine, dexamphetamine, lisdexamfetamine, and death, which identified 493 citations (344 after removal of duplicates). The eligibility of each study was assessed jointly by two investigators, leaving 20 relevant articles. We identified only a minimal increase in side-effects when ADHD medication (therapeutic doses) was taken with alcohol. None of the reviewed studies showed severe sequelae among those who had overdosed on ADHD medication and other coingestants, including alcohol. The numbers across all the papers studied remain too low to exclude uncommon effects. Also, studies of combined effects with novel psychoactive substances have not yet appeared in the literature. Nevertheless, no serious sequelae were identified from combining ADHD medication with alcohol/illicit substances from the pre-novel psychoactive substance era.

Type 1 diabetes mellitus is a major public health problem of increasing global concern, with potential neurological complications. A possible association exists between type 1 diabetes and subsequent epilepsy. This study evaluated the relationship between type 1 diabetes and epilepsy in Taiwan. Claims data from the Taiwan National Health Insurance Research Database were used to conduct retrospective cohort analyses. The study cohort contained 2568 patients with type 1 diabetes, each of whom was frequency-matched by sex, urbanisation of residence area and index year with ten patients without type 1 diabetes. Cox proportional hazard regression analysis was conducted to estimate the effects of type 1 diabetes on epilepsy risk. In patients with type 1 diabetes, the risk of developing epilepsy was significantly higher than that in patients without type 1 diabetes (p < 0.0001 for logrank test). After adjustment for potential confounders, the type 1 diabetes cohort was 2.84 times as likely to develop epilepsy than the control cohort was (HR 2.84 [95% CI 2.11, 3.83]). Patients with type 1 diabetes are at an increased risk of developing epilepsy. Metabolic abnormalities of type 1 diabetes, such as hyperglycaemia and hypoglycaemia, may have a damaging effect on the central nervous system and be associated with significant long-term neurological sequelae. The causative factors between type 1 diabetes and the increased risk of epilepsy require further investigation.

To assess the etiology and the late effects of penile fractures treated by immediate surgical intervention. Between 1986 and 2008, a total of 155 patients with penile fracture were treated surgically in our center. The interval from injury to presentation was between 1 and 96 hours. Those patients were contacted by mail or phone and were re-evaluated. All patients were re-evaluated by questionnaire and local examination. Patients with erectile dysfunction were evaluated by color Doppler ultrasonography. The most common cause of fracture of penis is sexual intercourse (51.5%). Unilateral and bilateral corporeal ruptures were present in 139 (89.7%) and 3 (1.9%) cases, respectively, whereas no tunical tear was found in 13 (8.4%) cases. Concomitant urethral injury was present in 14 (9%) cases. Long-term follow-up (>12 months) was available for 141 patients; among whom there was no complications in 108 (77%), painful erection in 2 (1.3%), penile deviation in 5 (3.2%), both in 1 (0.7%), erectile dysfunction in 11 (7.8%), and palpable scarring in 14 (10%). Scar formation was highly associated using nonabsorbable sutures (P <.001). Vigorous sexual intercourse was found to be the most common cause of penile fracture. Immediate surgical intervention has low morbidity, short hospital stay, rapid functional recovery, and no serious long-term sequelae. Nonabsorbable sutures should be avoided as it has a higher incidence of scar formation. 2010 Elsevier Inc. All rights reserved.

Incapacitating articular sequelae in the hip joint have been described for patients with late effects of poliomyelitis. In these patients, total hip arthroplasty (THA) has been associated with a substantial rate of dislocation. This study was conducted to evaluate the long-term clinical and radiologic outcomes of unconstrained THA in this specific group of patients. The study included 6 patients with ipsilateral polio who underwent primary THA between 1985 and 2006. Patients with polio who underwent THA on the nonparalytic limb were excluded. Mean follow-up was 119.5 months (minimum, 84 months). Clinical outcomes were evaluated with the modified Harris Hip Score (mHHS) and the visual analog scale (VAS) pain score. Radiographs were examined to identify the cause of complications and determine the need for revision surgery. All patients showed significantly better functional results when preoperative and postoperative mHHS (67.58 vs 87.33, respectively; P=.002) and VAS pain score (7.66 vs 2, respectively; P=.0003) were compared. Although 2 cases of instability were diagnosed, only 1 patient needed acetabular revision as a result of component malpositioning. None of the patients had component loosening, osteolysis, or infection. Unconstrained THA in the affected limb of patients with poliomyelitis showed favorable long-term clinical results, with improved function and pain relief. Nevertheless, instability may be a more frequent complication in this group of patients compared with the general population. [Orthopedics. 2017; 40(2):e255-e261.].

To explore the psychological consequences of experiencing symptomatic pulmonary embolism (PE). Qualitative interview-based study using interpretative phenomenological analysis. Outpatients who attended an anticoagulation clinic in a district general hospital. Patients attending an anticoagulation clinic following hospital admission for symptomatic PE were approached to participate. A total of 9 (4 women, 5 men) of 11 patients approached agreed to be interviewed. Participants were aged between 26 and 72 years and had previously experienced a PE between 9 and 60 months (median=26 months, mean=24 months). Audiotaped semistructured qualitative interviews were undertaken to explore participants experiences of having a PE and how it had affected their lives since. Data were transcribed and analysed using interpretative phenomenological analysis to identify emergent themes. Three major themes with associated subthemes were identified. Participants described having a PE as a life-changing experience comprising initial shock, followed by feeling of loss of self, life-changing decisions and behaviour modification. Features of post-traumatic stress disorder (PTSD) were described with flashbacks, hypervigilance and intrusive thoughts being most prevalent. Participants identified several areas of support needed for such patients including easier access to support through information giving and emotional support. Long-term consequences of venous thromboembolism go beyond the physical alone. Patients describe experiencing symptomatic PE to be a life-changing distressing event leading to behaviour modification and in some PTSD. It is likely that earlier psychological intervention may reduce such long-term sequelae.

Although the September 11, 2001, terrorist attacks were the largest human-made disaster in US history, there is little extant research documenting the attacks' consequences among those most directly affected, that is, persons who were in the World Trade Center towers. Data from a cross-sectional survey conducted 2-3 years after the attacks ascertained the prevalence of long-term, disaster-related posttraumatic stress symptoms and probable posttraumatic stress disorder (PTSD) in 3,271 civilians who evacuated World Trade Center towers 1 and 2. Overall, 95.6% of survivors reported at least 1 current posttraumatic stress symptom. The authors estimated the probable rate of PTSD at 15.0% by using the PTSD Checklist. Women and minorities were at an increased risk of PTSD. A strong inverse relation with annual income was observed. Five characteristics of direct exposure to the terrorist attacks independently predicted PTSD: being on a high floor in the towers, initiating evacuation late, being caught in the dust cloud that resulted from the tower collapses, personally witnessing horror, and sustaining an injury. Working for an employer that sustained fatalities also increased risk. Each addition of an experience of direct exposure resulted in a 2-fold increase in the risk of PTSD (odds ratio = 2.09, 95% confidence interval: 1.84, 2.36). Identification of these risk factors may be useful when screening survivors of large-scale terrorist events for long-term psychological sequelae.

The significance of experiences of war and migration in older age: long-term consequences in child survivors from the Dutch East Indies.

This study examines late consequences of war and migration in both non-clinical and clinical samples of child survivors of World War II. This is one of the very few studies on the mental health of children who were subjected to internment in camps, hiding, and violence under Japanese occupation in the Far East. It provides a unique case to learn about the significance of experiences of war and migration in later life. Long-term sequelae of the Japanese persecution in the Dutch East Indies (DEI) in child survivors were studied by analyzing sets of standardized questionnaires of 939 persons. Instruments dealt with post-traumatic responses, general health, and dissociation. Participants were recruited through community services and registers of clinical services. Discriminant analyses were conducted to evaluate the significance of early experiences in determining group belonging. Compared with age-matched controls that lived through the German occupation in the Netherlands during World War II, the child survivors from the DEI reported both more trauma-related experiences and mental health disturbances in later life. In particular, the number of violent events during the war, among which especially internment in a camp, contributed to the variation among groups, in support of the significance of these disruptive experiences at older age. The results underline the long-term significance of World War II-related traumatic experiences in the population of elderly child survivors who spent their childhood in the former DEI.

Botulinum toxin in the management of facial paralysis.

Complete flaccid facial paralysis, as well as the synkinetic and hyperkinetic sequelae of partial recovery, has significant impact on quality of life. Patients suffer from functional deficiencies, cosmetic deformity, discomfort and social consequences leading to emotional distress. Despite an extensive and sophisticated array of available interventions for facial reanimation, most patients have persistent issues that require consistent follow-up. In long-term management, botulinum toxin (BT) injection remains a critical tool in the treatment of the facial paralysis patient, particularly in the case of synkinesis, hyperkinesis and imbalance. We review the recent scientific literature and highlight key principles and developments in the use of BT in the management of facial paralysis, including less common applications for acute facial paralysis, hyperlacrimation and pseudoptosis. We reviewed the literature for the latest advances in the use of BT in facial paralysis, including applications and technique, as well as measurement tools and adjunct exercises. We also share our experience in treating our own patient population. BT continues to be a well tolerated and effective tool in the long-term management of facial paralysis, specifically in treating synkinesis, imbalance and hyperkinesis, as well as hyperlacrimation and pseudoptosis. Consistent measurement tools and adjunct neuromuscular retraining are crucial in the successful deployment of BT. Controversy exists as to whether BT should be used to manage facial paralysis during the acute phase, and whether BT application to the nonparalyzed face can improve long-term recovery in the paralyzed side.

Enterovirus 71 rhombencephalomyelitis with cardiopulmonary dysfunction has become an endemic problem in Taiwan since an epidemic outbreak in 1998. Such cases frequently involve significant morbidity and mortality. From October 2000-June 2008, we collected 10 consecutive patients diagnosed with enterovirus 71 rhombencephalomyelitis complicated by left heart failure, with or without pulmonary edema, and surviving more than 3 months after receiving extracorporeal life support. Follow-up neurologic outcomes were analyzed prospectively. The median duration of neurologic follow-up was 7 years and 2 months. Significant morbidities included bulbar dysfunction, respiratory failure, and flaccid quadriparesis. Eight patients exhibited bulbar dysfunction, and feeding tubes could be removed from four patients (median, 15.5 months). Respiratory failure was observed in seven patients. Three patients were gradually withdrawn from their tracheostomy tube (median period, 30 months). Intelligence tests revealed four patients with normal cognitive function, one with borderline cognitive function, and one with mild mental retardation. Four were bedridden survivors. Extracorporeal life support for critical enterovirus 71 rhombencephalomyelitis demonstrated decreased neurologic sequelae during long-term follow-up, allowing for decannulation of feeding and tracheostomy tubes, and resulting in improved cognitive function.

2015-06-01

Acute or subacute cerebellar inflammation is mainly caused by postinfectious, toxic, neoplastic, vascular, or idiopathic processes and can result in cerebellar ataxia. Previous magnetic resonance (MR) studies in single patients who developed acute or subacute ataxia showed varying imaging features. Eighteen patients presenting with acute and subacute onset of ataxia were included in this study. Cases of chronic-progressive/hereditary and noncerebellar causes (ischemia, multiple sclerosis lesions, metastasis, bleedings) were excluded. MR imaging findings were then matched with the clinical history of the patient. An underlying etiology for ataxic symptoms were found in 14/18 patients (postinfectious/infectious, paraneoplastic, autoimmune, drug-induced). In two of five patients without MR imaging findings and three of eight patients with minimal imaging features (cerebellar atrophy, slight signal alterations, and small areas of restricted diffusion), adverse clinical outcomes were documented. Of the five patients with prominent MR findings (cerebellar swelling, contrast enhancement, or broad signal abnormalities), two were lost to follow-up and two showed long-term sequelae. No correlation was found between the presence of initial MRI findings in subacute or acute ataxia patients and their long-term clinical outcome. MR imaging was more flagrantly positive in cases due to encephalitis.

Premature Ovarian Insufficiency - an update on recent advances in understanding and management

PubMed Central

Torrealday, Saioa; Kodaman, Pinar; Pal, Lubna

2017-01-01

Premature ovarian insufficiency is a complex and relatively poorly understood entity with a myriad of etiologies and multisystem sequelae that stem from premature deprivation of ovarian sex hormones. Timely diagnosis with a clear understanding of the various comorbidities that can arise from estrogen deficiency is vital to appropriately counsel and treat these patients. Prompt initiation of hormone therapy is critical to control the unsolicited menopausal symptoms that many women experience and to prevent long-term health complications. Despite ongoing efforts at improving our understanding of the mechanisms involved, any advancement in the field in recent decades has been modest at best and researchers remain thwarted by the complexity and heterogeneity of the underpinnings of this entity. In contrast, the practice of clinical medicine has made meaningful strides in providing assurance to the women with premature ovarian insufficiency that their quality of life as well as long-term health can be optimized through timely intervention. Ongoing research is clearly needed to allow pre-emptive identification of the at-risk population and to identify mechanisms that if addressed in a timely manner, can prolong ovarian function and physiology.

Hypothalamic Obesity in Craniopharyngioma Patients: Disturbed Energy Homeostasis Related to Extent of Hypothalamic Damage and Its Implication for Obesity Intervention

PubMed Central

Roth, Christian L.

2015-01-01

Hypothalamic obesity (HO) occurs in patients with tumors and lesions in the medial hypothalamic region. Hypothalamic dysfunction can lead to hyperinsulinemia and leptin resistance. This review is focused on HO caused by craniopharyngiomas (CP), which are the most common childhood brain tumors of nonglial origin. Despite excellent overall survival rates, CP patients have substantially reduced quality of life because of significant long-term sequelae, notably severe obesity in about 50% of patients, leading to a high rate of cardiovascular mortality. Recent studies reported that both hyperphagia and decreased energy expenditure can contribute to severe obesity in HO patients. Recognized risk factors for severe obesity include large hypothalamic tumors or lesions affecting several medial and posterior hypothalamic nuclei that impact satiety signaling pathways. Structural damage in these nuclei often lead to hyperphagia, rapid weight gain, central insulin and leptin resistance, decreased sympathetic activity, low energy expenditure, and increased energy storage in adipose tissue. To date, most efforts to treat HO have shown disappointing long-term success rates. However, treatments based on the distinct pathophysiology of disturbed energy homeostasis related to CP may offer options for successful interventions in the future. PMID:26371051

Background Paracetamol is used extensively during pregnancy, but studies regarding the potential neurodevelopmental sequelae of foetal paracetamol exposure are lacking. Method Between 1999 and 2008 all pregnant Norwegian women were eligible for recruitment into the prospective Norwegian Mother and Child Cohort Study. The mothers were asked to report on their use of paracetamol at gestational weeks 17 and 30 and at 6 months postpartum. We used data on 48 631 children whose mothers returned the 3-year follow-up questionnaire by May 2011. Within this sample were 2919 same-sex sibling pairs who were used to adjust for familial and genetic factors. We modelled psychomotor development (communication, fine and gross motor development), externalizing and internalizing behaviour problems, and temperament (emotionality, activity, sociability and shyness) based on prenatal paracetamol exposure using generalized linear regression, adjusting for a number of factors, including febrile illness, infections and co-medication use during pregnancy. Results The sibling-control analysis revealed that children exposed to prenatal paracetamol for more than 28 days had poorer gross motor development [β 0.24, 95% confidence interval (CI) 0.12–0.51], communication (β 0.20, 95% CI 0.01–0.39), externalizing behaviour (β 0.28, 95% CI 0.15–0.42), internalizing behaviour (β 0.14, 95% CI 0.01–0.28), and higher activity levels (β 0.24, 95% CI 0.11–0.38). Children exposed prenatally to short-term use of paracetamol (1–27 days) also had poorer gross motor outcomes (β 0.10, 95% CI 0.02–0.19), but the effects were smaller than with long-term use. Ibuprofen exposure was not associated with neurodevelopmental outcomes. Conclusion Children exposed to long-term use of paracetamol during pregnancy had substantially adverse developmental outcomes at 3 years of age. PMID:24163279

Anecdotal evidence suggests the frequently traumatic nature of female genital mutilation (FGM). At present, systematic research on the psychological sequelae of this tradition has remained limited. The study provides preliminary, high-quality psychodiagnostic data on potential psychopathological consequences of FGM, with a focus on posttraumatic stress disorder (PTSD), shutdown dissociation and other stress-related variables. We investigated a convenience sample of N = 167 women, supported by the women's affairs headquarters in Jijiga (capital of the Ethiopian Somali Region) and a local Ethiopian non-governmental organization. Our main outcome measures were PTSD (PSS-I) and shutdown dissociation (ShuD). We also assessed depression and anxiety (HSCL-25), major depression, substance abuse and dependence, suicidality and psychotic disorders (M.I.N.I.; sub-scales A., B., K., and L.). In addition, we collected hair samples to assess hair cortisol concentrations (HCC) as a neuroendocrinological measure. The majority of women endured FGM (FGM I: 36%, FGM II/III: 52%) and, regardless of the level of the physical invasiveness, almost all women reported having felt intense fear and/or helplessness. FGM II/III, the more invasive form, was associated with a greater vulnerability to PTSD symptoms (p < .001) and shutdown dissociation (p < .001). Symptoms of depression (p < .05) and anxiety (p < .01) were also elevated. Random forest regression with conditional inference trees revealed evidence of an alteration of the cortisol levels in relation to the age when FGM was experienced (< 1 year) and the invasiveness of the procedure. More extensive forms of FGM are associated with more severe psychopathological symptoms - particularly with an increased vulnerability to PTSD. Higher hair cortisol levels in women who experienced FGM before their first year of age or had more severe forms of FGM indicate long-term neuroendocrinological consequences of FGM and trauma in general on the stress system.

Herpes simplex encephalitis (HSE) occurs without regional and seasonal predilections. HSE is important to differentiate from arboviral encephalitis in endemic areas because of therapeutic potential of HSE. This study evaluates clinical features, MRI and laboratory findings which may help in differentiating HSE from Japanese encephalitis (JE). Confirmed patients with JE and HSE in last 10years were included. The presenting clinical symptoms including demographic information, seizure, behavioral abnormality, focal weakness and movement disorders were noted. Cranial MRI was done and location and nature of signal alteration were noted. Electroencephalography (EEG), cerebrospinal fluid (CSF), blood counts and serum chemistry were done. Outcome was measured by modified Rankin Scale (mRS). Death, functional outcome and neurological sequelae were noted at 3, 6 and 12months follow up, and compared between HSE and JE. Outcome was categorized as poor (mRS;>2) and good (mRS≤2). 97 patients with JE and 40 HSE were included. JE patients were younger than HSE and occurred in post monsoon period whereas HSE occurred throughout the year. Seizure (86% vs 40%) and behavioral abnormality (48% vs 10%) were commoner in HSE; whereas movement disorders (76% vs 0%) and focal reflex loss (42% vs 10%) were commoner in JE. CSF findings and laboratory parameters were similar in both the groups. Thalamic involvement in JE and temporal involvement in HSE were specific markers of respective encephalitis. Delta slowing on EEG was more frequent in JE than HSE. 20% JE and 30% HSE died in the hospital, and at 1year follow up JE patients showed better outcome compared to HSE (48% vs 24%). Memory loss (72% vs 22%) was the predominant sequelae in HSE. Seizure and behavioral abnormality are common features in HSE whereas focal reflex loss is commoner in JE. In a patient with acute encephalitis, thalamic lesion suggests JE and temporal lobe involvement HSE. Long term outcome in JE is better compared to HSE. Copyright © 2016 Elsevier B.V.

The purpose of this study was to compare the regional distribution of apoptotic cells in the near term ovine fetal brain caused by prolonged moderate hypoxia, as seen in placental insufficiency, and intermittent severe hypoxia, as seen in umbilical cord compression, which may then contribute to adverse neurodevelopment in the postnatal life. We hypothesized that apoptosis in the fetal brain will be increased in response to both prolonged moderate hypoxia and intermittent severe hypoxia. Twenty-one near term (126-127 days) sheep were divided into 3 groups: control (CON; n = 7), placental embolization (EMB; n = 7), and umbilical cord occlusion (UCO; n = 8). The EMB group had microsphere injections into the umbilical arterial circulation until the oxygen content was at 50% of baseline value. The UCO group had complete cord occlusion for 2 minutes every hour, 6 times a day for 2 consecutive days. At 4 pm on day 2, the animals were euthanized; fetal brains were fixed and prepared for apoptosis staining using the terminal uridine deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay method. In the cerebellar white matter, there was a 3-fold increase in the number of TUNEL positive cells per 1000 cells in both EMB and UCO animals as compared to CON (P = .017). There was also a significant increase in the frontal cortical grey matter (layers 1-3) in EMB animals as compared to CON (P = .014). As such, apoptosis in the near term fetal sheep brain is altered with both sustained moderate hypoxia and intermittent severe hypoxia in the latter part of pregnancy, with potential for long-term neurological sequelae. © The Author(s) 2015.

An increasing number of patients survive sepsis; however, we lack valid data on the long-term impact on morbidity from prospective observational studies. Therefore, we designed an observational cohort to quantify mid-term and long-term functional disabilities after intensive care unit (ICU)-treated sepsis. Ultimately, findings for the Mid-German Sepsis Cohort (MSC) will serve as basis for the implementation of follow-up structures for patients with sepsis and help to increase quality of care for sepsis survivors. All patients surviving ICU-treated sepsis are eligible and are recruited from five study centres in Germany (acute care hospital setting in Jena, Halle/Saale, Leipzig, Bad Berka, Erfurt; large long-term acute care hospital and rehabilitation setting in Klinik Bavaria Kreischa). Screening is performed by trained study nurses. Data are collected on ICU management of sepsis. On written informed consent provided by patients or proxies, follow-up is carried out by trained research staff at 3, 6 and 12 months and yearly thereafter. The primary outcome is functional disability as assessed by (instrumental) activities of daily living. Other outcomes cover domains like mortality, cognitive, emotional and physical impairment, and resource use. The estimated sample size of 3000 ICU survivors is calculated to allow detection of relevant changes in the primary outcome in sepsis survivors longitudinally. The study is conducted according to the current version of the Declaration of Helsinki and has been approved by four local/federal responsible institutional ethics committees and by the respective federal data protection commissioners. Results of MSC will be fed back to the patients and published in peer-reviewed journals.

M. tuberculosis is one of the prime killers from infectious diseases worldwide. Infections with multidrug-resistant variants counting for almost half a million new cases per year are steadily on the rise. Tuberculosis caused by extensively drug-resistant variants that are even resistant against newly developed or last resort antibiotics have to be considered untreaTable Susceptible tuberculosis already requires a six-months combinational therapy which requires further prolongation to treat drug-resistant infections. Such long treatment schedules are often accompanied by serious adverse effects causing patients to stop therapy. To tackle the global tuberculosis emergency, novel approaches for treatment need to be urgently explored. Host-directed therapies that target components of the defense system represent such a novel approach. In this review, we put a spotlight on neutrophils and neutrophil-associated effectors as promising targets for adjunct host-directed therapies to improve antibiotic efficacy and reduce both, treatment time and long-term pathological sequelae.

Echocardiographic Assessment of Mantle Radiation Mitral Stenosis.

PubMed

Bastiaenen, Rachel; Sneddon, James; Sharma, Rajan

2016-02-01

The long-term sequelae of mantle radiotherapy include lung disease and cardiac disorders. Dyspnea on exertion is a common complaint and can be due to one or more pathologies. We describe a case of mantle radiotherapy-induced mitral stenosis, characterized by aorto-mitral continuity calcification and absent commissural fusion which precludes balloon valvotomy. The latency period is long, and this patient presented 42 years after radiotherapy. Importantly, as previously described with radiation-induced valve disease, significant mitral stenosis developed 10 years after surgery for significant aortic stenosis. Two-dimensional and three-dimensional transthoracic and transesophageal echocardiography should be considered during assessment of symptomatic survivors of Hodgkin's disease where the index of suspicion for valvular stenosis increases over time. Given the natural history of mantle radiation valvular disease, a lower threshold for surgical intervention in radiation-induced mitral stenosis may need to be considered if cardiac surgery is planned for other reasons in order to avoid repeated sternotomy in patients with prior irradiation. © 2015, Wiley Periodicals, Inc.

Improving the Patient Experience by Implementing an ICU Diary for Those at Risk of Post-intensive Care Syndrome.

2017-03-01

The critical care literature in the US has recently brought attention to the impact an ICU experience can have long after the patient survives critical illness, particularly if delirium was present. Current recommendations to mitigate post-intensive care syndrome (PICS) are embedded in patient and family-centered care and aim to promote family presence in the ICU, provide support for decision-making, and enhance communication with the health-care team. Evidence-based interventions are few in number but include use of an ICU diary to minimize the psychological and emotional sequelae affecting patients and family members in the months following the ICU stay. In this paper we describe our efforts to implement an ICU diary and solicit feedback on its role in fostering teamwork and communication between patients, family members, and ICU staff. Next steps will involve a PICS follow-up clinic where trained staff will coordinate specialty referrals and perform long-term monitoring of mental health and other quality of life outcomes.

Short-Term Plasticity and Long-Term Potentiation in Magnetic Tunnel Junctions: Towards Volatile Synapses

NASA Astrophysics Data System (ADS)

Sengupta, Abhronil; Roy, Kaushik

2016-02-01

Synaptic memory is considered to be the main element responsible for learning and cognition in humans. Although traditionally nonvolatile long-term plasticity changes are implemented in nanoelectronic synapses for neuromorphic applications, recent studies in neuroscience reveal that biological synapses undergo metastable volatile strengthening followed by a long-term strengthening provided that the frequency of the input stimulus is sufficiently high. Such "memory strengthening" and "memory decay" functionalities can potentially lead to adaptive neuromorphic architectures. In this paper, we demonstrate the close resemblance of the magnetization dynamics of a magnetic tunnel junction (MTJ) to short-term plasticity and long-term potentiation observed in biological synapses. We illustrate that, in addition to the magnitude and duration of the input stimulus, the frequency of the stimulus plays a critical role in determining long-term potentiation of the MTJ. Such MTJ synaptic memory arrays can be utilized to create compact, ultrafast, and low-power intelligent neural systems.

Concussion is confusing us all.

PubMed

Sharp, David J; Jenkins, Peter O

2015-06-01

It is time to stop using the term concussion as it has no clear definition and no pathological meaning. This confusion is increasingly problematic as the management of 'concussed' individuals is a pressing concern. Historically, it has been used to describe patients briefly disabled following a head injury, with the assumption that this was due to a transient disorder of brain function without long-term sequelae. However, the symptoms of concussion are highly variable in duration, and can persist for many years with no reliable early predictors of outcome. Using vague terminology for post-traumatic problems leads to misconceptions and biases in the diagnostic process, producing uninterpretable science, poor clinical guidelines and confused policy. We propose that the term concussion should be avoided. Instead neurologists and other healthcare professionals should classify the severity of traumatic brain injury and then attempt to precisely diagnose the underlying cause of post-traumatic symptoms.

Extra-articular fractures of the digital metacarpals and phalanges of the long fingers.

PubMed

Le Nen, D

2014-02-01

Metacarpal and phalangeal fractures of the long fingers are the result of trauma occurring under extremely varied circumstances. As a consequence, the clinical presentation varies greatly, with every bone and joint potentially being involved. Each step of their treatment is crucial, although the benign appearance of these injuries can lead to steps being missed: diagnostic phase with clinical examination and radiographs; therapeutic phase where the most suitable treatment is chosen, which combines mobilization of the digital chains as soon as possible and in every patient; follow-up phase with regular monitoring to detect any complications, especially secondary displacement, and verify that good progress is being made during rehabilitation. The goal of any fracture treatment is to preserve or restore the anatomy, with the emphasis here being on the stability and mobility of the digital chains. The potential progression towards serious functional sequelae (pain, instability or stiffness in hand) and the resulting significant socio-economic repercussions must be at the forefront of a surgeon's mind early on during the initial care of any finger or hand trauma.

Electro-encephalographic disturbances due to chronic toxin abuse in young people, with special reference to glue-sniffing.

PubMed

Griesel, R D; Jansen, P; Richter, L M

1990-11-03

A study was carried out in order to document any abnormalities in the electro-encephalogram (EEG) that might appear in young adolescents who have deliberately inhaled the range of volatile substances loosely referred to as 'glue'. The EEGs of a group of 'street children' being assisted in a Johannesburg shelter were examined. The records were analysed for any clinical abnormalities and also subjected to spectral analysis in order to examine the overall characteristics of frequency, power and spatial distribution. The EEGs clearly revealed that, although at the time of the examination the subjects were ostensibly abstinent, both clinical and normative evidence of continuing brain disturbance was present. It was concluded that glue sniffing is likely to have long term electrocerebral sequelae.

Treatment of PCOS in adolescence.

2006-06-01

Polycystic ovary syndrome (PCOS) is increasingly being recognized in adolescent girls seeking treatment for signs and symptoms of hyperandrogenism. It is difficult to diagnose PCOS in adolescents, therefore a high index of suspicion is necessary. Timely screening and treatment are crucial because another important component of the syndrome is insulin resistance/hyperinsulinemia increasing the risk for type 2 diabetes, dyslipidemia, and cardiovascular sequelae. Diagnosis of PCOS in adolescents should include a thorough family history, exclusion of other causes of hyperandrogenism, and appropriate laboratory evaluation. The scarcity of controlled clinical trials makes treatment controversial. Therapeutic options include lifestyle intervention, oral contraceptive pills, and insulin sensitizers. Long-term follow-up is needed to determine the effectiveness of these approaches in changing the natural history of the reproductive and metabolic outcomes without causing undue harm.

Retroperitoneal abscesses in seven dogs.

Marvel, Sarah J; MacPhail, Catriona M

2013-01-01

Retroperitoneal abscesses, although uncommon, are clinically important. Medical records of seven dogs with naturally occurring retroperitoneal infections from 1999 to 2011 were reviewed to document historical, examination, clinicopathologic, imaging, and surgical findings; etiologic agents; and outcome. Middle-aged sporting dogs were most commonly affected. Dogs were febrile with evidence of either abdominal or lumbar pain. Although traditional radiography can aid in diagnosis, ultrasound appeared to be a more sensitive indicator of disease within the retroperitoneal space. Numerous bacteria were isolated from the abscesses, with anaerobic and facultative anaerobic bacteria being the most commonly isolated. Etiology was largely unknown, but migrating plant material was often suspected. Resolution of the infection required surgical intervention as well as prolonged antibiotic therapy. Although recurrence is possible, outcome can be favorable with no long-term sequela.

ABSTRACT Attempts to produce a vaccine to protect against Chlamydia trachomatis-induced trachoma were initiated more than 100 years ago and continued for several decades. Using whole organisms, protective responses were obtained. However, upon exposure to C. trachomatis, disease exacerbation developed in some immunized individuals, precluding the implementation of the vaccine. Evidence of the role of C. trachomatis as a sexually transmitted pathogen started to emerge in the 1960s, and it soon became evident that it can cause acute infections and long-term sequelae in women, men, and newborns. The main focus of this minireview is to summarize recent findings and discuss formulations, including antigens, adjuvants, routes, and delivery systems for immunization, primarily explored in the female mouse model, with the goal of implementing a vaccine against C. trachomatis genital infections.

Medulloblastoma is the most common malignant brain tumour diagnosed in children. Over the last few decades, advances in radiation and chemotherapy have significantly improved the odds of survival. Nevertheless, one third of all patients still succumb to their disease, and many long-term survivors are afflicted with neurocognitive sequelae. Large-scale multi-institutional efforts have provided insight into the transcriptional and genetic landscape of medulloblastoma. Four distinct subgroups of medulloblastoma have been identified, defined by distinct transcriptomes, genetics, demographics and outcomes. Integrated genomic profiling of each of these subgroups has revealed distinct genetic alterations, driving pathways and in some instances cells of origin. In this review, we highlight, in a subgroup-specific manner, our current knowledge of the genetic and molecular alterations in medulloblastoma and underscore the possible avenues for future therapeutic intervention.

A 38-year-old gentleman tripped and fell face first onto the wing of an ornamental brass eagle. This penetrated the inferomedial aspect of the right orbit, breaching the lamina papyracea to extend into the ethmoid sinuses and reaching the dura of the anterior cranial fossa. The foreign body was removed in theater under a joint ophthalmology and ENT procedure. The patient was left with reduced visual acuity in the right eye but no other long-term sequelae. Transorbital penetrating injury presents unusual challenges to investigation and management requiring a multidisciplinary approach to prevent significant morbidity and mortality. If managed well the prognosis is good. PMID:25383154

Kaufman, Melissa R

2018-02-26

Classic bladder exstrophy (BE) remains one of the most demanding reconstructive challenges encountered in urology. In female BE patients, the long-term sequela of both primary and revision genitoplasty, as well as intrinsic pelvic floor deficits, predispose adult women to significant issues with sexual function, pelvic organ prolapse (POP), and complexities with reproductive health. Contemporary data suggest 30-50% of women with BE develop prolapse at a mean age of 16 years. Most women will require revision genitoplasty for successful sexual function, although in some series over 40% report dyspareunia. Current management for pregnancy includes elective cesarean section with involvement of high-risk obstetrics and urologic surgery. This review encapsulates contemporary concepts of etiology, prevalence, and management of POP and pregnancy in the adult female BE patient.

Continued care in patients with encephalitis and prolonged status epilepticus (SE) is controversial. Limited data is available on the functional and cognitive outcomes. In a prospective cohort study from 2007 to 2016, patients with acute encephalitis and SE were reviewed. Long-term outcomes including motor disability (modified Rankin Scale, mRS), daily living skills (activities of daily living, ADL), cognitive ability (modified Telephone Interview for Cognitive Status, TICS-M) and epilepsy sequelae, were evaluated in those survivors at 12-month follow-up. At the 12-month follow-up, 72 patients were recruited, who got a median score of 14 on the total ADL. 68% patients remained independent in their daily activities (mRS≤2). Post-SE symptomatic epilepsy was observed in 49% patients. 62 patients achieved a median score of 40 on the TICS-M and 14 on the TICS-M memory. Patients with autoimmune encephalitis were less prone to post-SE symptomatic epilepsy (18% vs. 58%, P=0.005) but lower TICS-M memory score than those with viral encephalitis (8.5 vs. 15, P=0.017). Compared to non-refractory status epilepticus (RSE), patients with RSE had a longer stay in NCU (39 vs. 26, P=0.002), more in-hospital complications and post-SE symptomatic epilepsy (67% vs. 33%, P=0.005). Long-term outcomes including ADL, mRS, and TICS-M were not significantly different between patients with RSE and non-RSE or between patients with long (≥4h) and short duration (<4h) of SE. Survival with favorable functional recovery was promising after prolonged RSE in patients with acute encephalitis. This article is protected by copyright. All rights reserved.

Severe acute hypophosphatemia during renal replacement therapy adversely affects outcome of critically ill patients with acute kidney injury.

Schiffl, Helmut; Lang, Susanne M

2013-02-01

Hypophosphatemia during renal replacement therapy (RRT) is common in critically ill patients with acute kidney injury (AKI). The clinical consequences of RRT-induced phosphate depletion are not well defined in this patient population, and there is no evidence that intravenous sodium phosphate supplementation (PS) prevents the clinical sequelae of acute hypophosphatemia. The purpose of this retrospective analysis of the Acute Renal Support Registry of the University of Munich was to examine the association between severe hypophosphatemia and severity of and recovery from AKI. 289 ICU patients with AKI on intermittent hemodialysis (IHD) were included in the study. One hundred and forty-nine patients received PS during IHD. Outcomes were short-term (at discharge) and long-term (at 1 year) recovery of renal function and mortality. The two patient groups did not differ in demographics, clinical features, renal characteristics, and frequency of hypophosphatemia at initiation of IHD. Without PS, the frequency of hypophosphatemia increased from 20 to 35%. Severe hypophosphatemia was found in 50% of these patients. By comparison, PS was not associated with an increased frequency of hypophosphatemia. Compared with patients with acute phosphate depletion, patients receiving PS developed less oliguria during IHD, had shorter duration of AKI, higher incidence of complete renal recovery at discharge, and a lower risk of de novo chronic kidney disease. Hypophosphatemia was associated with higher all-cause in-hospital mortality and higher risk of long-term mortality. This multicenter study indicates for the first time that hypophosphatemia during IHD adversely affects short- and long-term outcome of critically-ill patients with AKI. The clinical consequences of the acute hypophosphatemic syndrome may be prevented by PS.

Traumatic dental injuries of the primary dentition (TDI-p) have a global prevalence of approximately 11%-47%. They have immediate and long-term effects. Original research analysing the long-term sequelae of TDI-p on permanent dentition (LSP) are few in number. The aim of this study was to explore the correlation between age of TDI-p, type of TDI-p and LSP. Retrospective analysis of patient data from 2008-2017, reporting with LSP due to TDI-p, was performed. Uniform protocols and complete radiographic-photographic records were analysed. There were 638 LSP reported with 596 teeth having complete records. There were 286 children with 153 males (53.5%) and 133 females (46.5%). Mean age of TDI-p causing LSP was 36.57 ± 11.51 months, with severity increasing in the younger age group. The highest number of LSP was associated with avulsion injuries (218, 36.58%), and the odds ratio of the type of TDI-p affect the severity of LSP was 2.0163. Mean age of reporting was 8.54 ± 2.19 years and was lowest for enamel discolorations. Most LSP were not associated with any associated feature (AF), although impaction was highest among all AF (63, 10.57%). Age and type of TDI-p affect LSP, with the former being the stronger determinant of its severity. Mean age of reporting of LSP is dependent upon both type of LSP and AF. LSP due to TDI-p can further be graded in terms of severity. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background: Excessive gestational weight gain (GWG) is associated with postpartum weight retention (PPWR) and abdominal adiposity, but long-term effects are understudied in low-income and minority populations at high risk of obesity and associated sequelae. Objective: We examined associations between GWG and long-term PPWR and adiposity in a prospective cohort of African American and Dominican mothers in the Bronx and Northern Manhattan. Design: Women (n = 302) were enrolled during pregnancy and were followed for 7 y postpartum. Linear regression was used to relate excessive GWG [greater than 2009 Institute of Medicine (IOM) guidelines] to outcomes [percentage body fat and long-term PPWR (change in weight from prepregnancy to 7 y postpartum)], adjusting for covariates and included an interaction term between prepregnancy body mass index (BMI; in kg/m2) and GWG. Results: Mean ± SD prepregnancy BMI and total GWG were 25.6 ± 5.8 (42% of women had BMI ≥25) and 16.6 ± 7.8 kg (64% of women had total GWG greater than IOM guidelines), respectively. Associations between GWG and long-term PPWR and the percentage body fat varied by prepregnancy BMI (P-interaction ≤ 0.06); excessive GWG was associated with a higher percentage body fat and greater long-term PPWR in mothers with lower prepregnancy BMI. To illustrate the interaction, a predicted covariate-adjusted model, which was used to derive estimates for the percentage body fat and PPWR associated with excessive GWG, was estimated for 2 prepregnancy BMI examples. For a woman with prepregnancy BMI of 22, excessive GWG was associated with 3.0% higher body fat (P < 0.001) and a 5.6-kg higher PPWR (P < 0.001); however, for a woman with a prepregnancy BMI of 30, excessive GWG was associated with 0.58% higher body fat (P = 0.55) and 2.06 kg PPWR (P = 0.24). Conclusions: Long-term adiposity and PPWR in low-income African American and Dominican mothers were predicted by interacting effects of prepregnancy BMI and excessive GWG. The provision of support for mothers to begin pregnancy at a healthy weight and to gain weight appropriately during pregnancy may have important lasting implications for weight-related health in this population.

Excessive gestational weight gain (GWG) is associated with postpartum weight retention (PPWR) and abdominal adiposity, but long-term effects are understudied in low-income and minority populations at high risk of obesity and associated sequelae. We examined associations between GWG and long-term PPWR and adiposity in a prospective cohort of African American and Dominican mothers in the Bronx and Northern Manhattan. Women (n = 302) were enrolled during pregnancy and were followed for 7 y postpartum. Linear regression was used to relate excessive GWG [greater than 2009 Institute of Medicine (IOM) guidelines] to outcomes [percentage body fat and long-term PPWR (change in weight from prepregnancy to 7 y postpartum)], adjusting for covariates and included an interaction term between prepregnancy body mass index (BMI; in kg/m(2)) and GWG. Mean ± SD prepregnancy BMI and total GWG were 25.6 ± 5.8 (42% of women had BMI ≥25) and 16.6 ± 7.8 kg (64% of women had total GWG greater than IOM guidelines), respectively. Associations between GWG and long-term PPWR and the percentage body fat varied by prepregnancy BMI (P-interaction ≤ 0.06); excessive GWG was associated with a higher percentage body fat and greater long-term PPWR in mothers with lower prepregnancy BMI. To illustrate the interaction, a predicted covariate-adjusted model, which was used to derive estimates for the percentage body fat and PPWR associated with excessive GWG, was estimated for 2 prepregnancy BMI examples. For a woman with prepregnancy BMI of 22, excessive GWG was associated with 3.0% higher body fat (P < 0.001) and a 5.6-kg higher PPWR (P < 0.001); however, for a woman with a prepregnancy BMI of 30, excessive GWG was associated with 0.58% higher body fat (P = 0.55) and 2.06 kg PPWR (P = 0.24).

1973-01-01

Three obstetric groups matched for parity, age, color, marital and socioeconomic status, were compared for the psychosocial antecedents to abortion or term delivery and sequelae that did exist. One group had induced abortion by suction curettage, the second had induced abortion by saline injection, and the third had term delivery. 373 women were interviewed during pregnancy; 211 were included in follow-up after an average of 16 months for abortion patients and 13 months for the term delivery group. The 373 women received a structured 90-minute interview about family relationships, consort relationships, living arrangements, income, education, religious behavior, sexual behavior, contraceptive knowledge and use, pregnancy history and desired family size. The Srole Anomia scale and the Rosenberg Self-Esteem scale were also used. At the followup interview, similar questions were asked and the two attitude scales were again presented. The MMPI (Minnesota Multiphasic Personality Inventory) and the SCL (Symptom Check List) were also used. 12% of the 211 follow-up scored higher than 70 on the MMPI for mania and psychopathy scales; these women were evenly divided among the three groups. SCL scales showed the three groups of patients to be similar after abortion or birth, with the only statistically significant difference being the suction curettage group, which had fewer complaints after abortion than either of the other two groups. There was no difference on the anomia or self-esteem scale between pre- or post-procedure for any of the groups. The data suggest neither great harm nor great benefit with regard to these variables due to either early or late abortion or term birth. Early abortion by suction curettage was possibly more therapeutic than carrying a pregnancy to term. There were striking improvements with regard to contraceptive use after the procedure. 71% of each group used effective contraception for more than 12 months after abortion or birth: a 20% increase for the term birth group, a 13% increase for the suction curettage group, and a 26% increase for the saline abortion group. Among abortion patients, those found to have low self-esteem, low contraceptive knowledge, high alienation, and who delayed in seeking abortion were related to long recovery times, a high MMPI psychopathology scale, and a number of unpleasant body symptoms post-abortion. These patients could be predicted with accuracy 32% better than chance alone.

Gastroenterological emergencies in the tropics.

PubMed

Cook, G C

1991-12-01

Significant differences exist in the prevalence of most gastroenterological emergencies in tropical compared with temperate countries. Both ethnic and environmental (often clearly defined geographically) factors are relevant. The major oesophageal lesions which can present acutely in tropical countries are varices and carcinoma; bleeding and obstruction are important sequelae. Peptic ulcer disease (and its complications), often associated (not necessarily causally) with Helicobacter pylori infection, has marked geographical variations in incidence. Emergencies involving the small intestine are dominated by severe dehydration, and its sequelae, resulting from secretory diarrhoea, most notably cholera. However, enteritis necroticans ('pig bel' disease), paralytic ileus (sometimes caused by antiperistaltic agents) and obstruction (secondary to luminal helminths, volvulus and intussusception) are other important problems, especially in infants and children. Enteric fever is occasionally complicated by perforation and haemorrhage; the former (which is notoriously difficult to manage) is accompanied by significant mortality. Ileocaecal tuberculosis is a major cause of right iliac fossa pathology--sometimes associated with malabsorption; amoeboma is an important clinical differential diagnosis. The colon can be involved in invasive Entamoeba histolytica infection (which, like complicated enteric fever, is difficult to manage if the fulminant form, with perforation, ensues), shigellosis, volvulus and intussusception. Acute colonic dilatation occasionally follows Salmonella sp., Shigella sp., Campylobacter jejuni, Yersinia enterocolitica and rarely E. histolytica infections. Acute hepatocellular failure is a major cause of morbidity and mortality in the tropics and subtropics. It usually results from viral hepatitis (HBV, sometimes complicated by HDV, and HCV), but there is a long list of differential diagnoses. Hepatotoxicity resulting from herbs, chemotherapeutic agents or alcohol also occurs not infrequently. Chronic liver disease and its sequelae (often long-term results of viral hepatitis) are commonplace. Haematemesis and hepatocellular failure are usually very difficult to manage due to a lack of sophisticated support techniques in developing countries. Invasive hepatic amoebiasis usually responds well to medical management; however, spontaneous perforation can occur and the consequences of this are serious. Pyogenic liver abscess, although far less common than amoebic 'abscess', carries a bad prognosis whatever the method(s) of management. Hydatidosis and schistosomiasis also involve the liver, and helminthiases are important in the context of biliary tract disease. Gall stones are unusual in most tropical settings. Acute pancreatitis is overall unusual, but chronic calcific pancreatitis can present as an acute abdominal emergency.

Methyl alcohol intoxication is a global problem with high mortality and long-term visual sequelae and severe brain damage in survivors. The role of neuroinflammation in the mechanisms of methyl alcohol-induced toxic brain damage has not been well studied. We measured the acute concentrations and dynamics of lipoxins LxA4 and LxB4 and the interleukins IL-4, IL-5, IL-9, IL-10, and IL-13 in the serum of patients treated with methyl alcohol poisoning and the follow-up concentrations in survivors two years after discharge from the hospital. A series of acute measurements was performed in 28 hospitalized patients (mean age 54.2 ± 5.2 years, mean observation time 88 ± 20 h) and the follow-up measurements were performed in 36 subjects who survived poisoning (including 12/28 survivors from the acute group). Visual evoked potentials (VEP) and magnetic resonance imaging of the brain (MRI) were performed to detect long-term visual and brain sequelae of intoxication. The acute concentrations of inflammatory mediators were higher than the follow-up concentrations: LxA4, 62.0 ± 6.0 vs. 30.0 ± 5.0 pg/mL; LxB4, 64.0 ± 7.0 vs. 34.0 ± 4.0 pg/mL; IL-4, 29.0 ± 4.0 vs. 15.0 ± 1.0 pg/mL; IL-5, 30.0 ± 4.0 vs. 13.0 ± 1.0 pg/mL; IL-9, 30.0 ± 4.0 vs. 13.0 ± 1.0 pg/mL; IL-10, 38.0 ± 5.0 vs. 16.0 ± 1.0 pg/mL; IL-13, 35.0 ± 4.0 vs. 14.0 ± 1.0 pg/mL (all p < 0.001). The patients with higher follow-up IL-5 concentration had prolonged latency P1 (r = 0.413; p = 0.033) and lower amplitude N1P1 (r = -0.498; p = 0.010) of VEP. The higher follow-up IL-10 concentration was associated with MRI signs of brain necrotic damage (r = 0.533; p = 0.001) and brain hemorrhage (r = 0.396; p = 0.020). Our findings suggest that neuroinflammation plays an important role in the mechanisms of toxic brain damage in acute methyl alcohol intoxication. Copyright © 2018 Elsevier B.V. All rights reserved.

Sport-related concussive convulsions: a systematic review.

PubMed

Kuhl, Nicholas O; Yengo-Kahn, Aaron M; Burnette, Hannah; Solomon, Gary S; Zuckerman, Scott L

2018-02-01

The incidence of sport-related concussion (SRC) continues to rise. Presentations of concussed athletes vary from subtle symptoms to notable signs. Between the 4th and 5th iterations of the Concussion in Sport Group (CISG) guidelines, concussive convulsions were removed as a modifying factor, but little evidence or discussion supported this change. While considerable research exists regarding post-traumatic epilepsy in moderate to severe traumatic brain injury, convulsions following SRC are relatively understudied. There is no clear consensus on the prevalence of convulsions, seizures, or the management of these entities following SRC. The aim of this review was to assess the state of the literature, describe the management trends of concussive convulsions and post-traumatic epilepsy in the SRC population, and provide evidence and guidance for the management of these athletes. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were adapted for a review of heterogeneous literature. English-language titles and abstracts published prior to June 2017 were searched systematically across four electronic databases. Primary peer-reviewed journal articles were included if they reported individuals of any age or gender who suffered a concussion or mild traumatic brain injury that was associated with seizure activity during a sports/recreational event. Of 852 records screened for review, 58 full-text articles were assessed for eligibility. Eight studies with 130 athletes total met the inclusion criteria. Of these individuals suffering a SRC convulsion or a post-concussive seizure, 0.8% received antiepileptic medications, 24.6% underwent electroencephalography, and 30.8% underwent brain imaging. The mean time until the participant returned to play was 14.8 days. Only 6.9% developed long-term sequelae over a mean follow-up time of 3.3 years. The current literature describing concussive convulsions and post-concussion seizure in sports is limited. A void of primary literature concerning the management of patients with concussive convulsions or seizures and the long-term sequelae among this population remains. However, the evidence available suggests that concussive convulsions do not need to be a primary modifying factor in the management of SRC.

The Wenchuan earthquake was China's worst natural disaster of the past three decades. Although the psychological sequelae of disasters can last for many years, the long-term sequelae and their risk factors tend to receive little research attention. The objectives of the present study were to estimate the prevalences of symptomalogical PTSD and depression among survivors 8 years after the Wenchuan earthquake, and to identify the shared and unshared risk factors associated with PTSD and depression, using data from a cross-sectional survey. 1369 participants were recruited from two different sites in the areas that were severely affected by the earthquake. Symptomalogical PTSD was assessed by the Impact of Event Scale-Revised (IES-R). The Chinese edition of the Center for Epidemiologic Studies Depression Scale (CES-D) was used to assess depression. Traumatic exposure to the Wenchuan earthquake was assessed using an exposure checklist designed by this study. Eight years after the Wenchuan earthquake, 11.8% of the respondents had symptomalogical PTSD, and 24.8% of respondents had probable depression. The results also indicated that female gender, low education, poor perceived health, and traumatic experiences after the earthquake were associated with higher odds of both PTSD and depression among survivors. Direct exposure to the earthquake was associated with comorbid symptomalogical PTSD and depression (OR=1.86; 95% CI=1.42, 2.44). Those having only depression were more likely to be unmarried/divorced/widowed, and to have experienced fear at the time of the earthquake (OR=1.34; 95% CI=1.04, 1.72), while those with only symptomalogical PTSD were likely to be from the township of Yongan as opposed to Guangji (OR=1.86; 95% CI=1.06, 3.31). This is a cross-sectional study, and thus is insufficient for determining causal relationships with regard to chronic PTSD or depression. The results of this study indicate that symptomalogical PTSD and depression persist among many survivors of the Wenchuan earthquake, 8 eight years later. Objective earthquake exposure is associated with symptomalogical PTSD, while subjective exposure is associated with long-term depression. Copyright © 2016 Elsevier B.V. All rights reserved.

An event in which electronic insulation consisting of polytetrafluoroethylene undergoes thermodegradation on the Space Station Freedom is considered experimentally and theoretically from the initial chemistry and convective transport through pulmonary deposition in humans. The low-gravity enviroment impacts various stages of event simulation. Vapor-phase and particulate thermodegradation products were considered as potential spacecraft contaminants. A potential pathway for the production of ultrafine particles was identified. Different approaches to the simulation and prediction of contaminant transport were studied and used to predict the distribution of generic vapor-phase products in a Space Station model. A lung transport model was used to assess the pulmonary distribution of inhaled particles, and, finally, the impact of adaptation to low gravity on the human response to this inhalation risk was explored on the basis of known physiological modifications of the immune, endocrine, musculoskeletal and pulmonary systems that accompany space flight.

Incidence of death and potentially life-threatening near-miss events in living donor hepatic lobectomy: a world-wide survey.

The incidence of morbidity and mortality after living donor liver transplantation (LDLT) is not well understood because reporting is not standardized and relies on single-center reports. Aborted hepatectomies (AHs) and potentially life-threatening near-miss events (during which a donor's life may be in danger but after which there are no long-term sequelae) are rarely reported. We conducted a worldwide survey of programs performing LDLT to determine the incidence of these events. A survey instrument was sent to 148 programs performing LDLT. The programs were asked to provide donor demographics, case volumes, and information about graft types, operative morbidity and mortality, near-miss events, and AHs. Seventy-one programs (48%), which performed donor hepatectomy 11,553 times and represented 21 countries, completed the survey. The average donor morbidity rate was 24%, with 5 donors (0.04%) requiring transplantation. The donor mortality rate was 0.2% (23/11,553), with the majority of deaths occurring within 60 days, and all but 4 deaths were related to the donation surgery. The incidences of near-miss events and AH were 1.1% and 1.2%, respectively. Program experience did not affect the incidence of donor morbidity or mortality, but near-miss events and AH were more likely in low-volume programs (≤50 LDLT procedures). In conclusion, it appears that independently of program experience, there is a consistent donor mortality rate of 0.2% associated with LDLT donor procedures, yet increased experience is associated with lower rates of AH and near-miss events. Potentially life-threatening near-miss events and AH are underappreciated complications that must be discussed as part of the informed consent process with any potential living liver donor.

Cerebral Malaria (CM) is a clinical syndrome defined by the World Health Organization (WHO) as a potentially reversible diffuse encephalopathy characterized mainly by coma and the presence of asexual forms of Plasmodium falciparum parasites in peripheral blood smears in the absence of other causes of encephalopathy. A wide range of clinical manifestations follows the disease including cognitive, behavioral and motor dysfunctions, seizures and coma. The underlying mechanisms of CM pathogenesis remain incompletely understood although vascular, immunological and metabolic changes have been described. The classical treatment of CM is based on the administration of antimalarial drugs, especially chloroquine and artemisinin derivates as artesunate. Even with treatment, 15 to 20% of children with CM die and approximately 10 to 17% of those who survive remain with significant long-term cognitive impairment. In this context, neuroprotective and adjuvant therapies have been recently investigated in clinical and experimental studies of CM in an attempt to improve cognitive outcome. A poor understanding of pathophysiological mechanisms, properties of compounds used and patient selection have contributed to the lack of success of these interventions. This review discusses clinical aspects of cognitive sequelae, possible mechanisms involved in the brain injury, perspectives and limitations regarding the pharmacological strategies to improve cognitive outcome in CM.

Despite increased interest regarding the potentially long-term negative impact of chronic traumatic brain injury, limited research has been conducted regarding such injuries and neurological outcomes in real world settings. To increase understanding regarding the relationship between sparring (e.g., training under the tutelage of an experienced boxing coach for the purpose of improving skills and/or fitness) and neurological functioning, professional boxers (n = 237) who competed in Maryland between 2003 and 2008 completed measures regarding sparring exposure (Cumulative Sparring Index, CSI) and performance on tests of cognition (Symbol Digit Modalities Test, SDMT) and balance (Sharpened Romberg Test, SRT). Measures were completed prior to boxing matches. Higher scores on the CSI (increased sparring exposure) were associated with poorer performance on both tests of cognition (SDMT) and balance (SRT). A threshold effect was noted regarding performance on the SDMT, with those reporting CSI values greater than about 150 experiencing a decline in cognition. A history of frequent and/or intense sparring may pose a significant risk for developing boxing associated neurological sequelae. Implementing administration of clinically meaningful tests before bouts, such as the CSI, SDMT, and/or the SRT, as well as documentation of results into the boxer's physicals or medical profiles may be an important step for improving boxing safety.

As a new hormone, betatrophin has gained attention as a potential new target to combat insulin resistance (IR) and diabetes. Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder among women of the reproductive age with long term sequelae which include IR and metabolic syndrome. The aim of this study is to evaluate the circulating plasma betatrophin levels in overweight/obese or lean women with or without PCOS and also to elucidate possible correlations with anthropometric and metabolic parameters. Thirty-two patients with PCOS as well as fifty-three control subjects were enrolled after obtaining informed written consent. Clinical and biochemical parameters of all subjects were determined. Plasma adiponectin, GLP-1 and betatrophin levels were measured by ELISA. Plasma betatrophin levels were significantly increased in lean patients with PCOS compared with lean and obese controls. Moreover, in PCOS group, betatrophin levels were significantly negatively correlated with waist hip ratio (WHR), fasting insulin level (FINS) and HOMA-IR, whereas, significantly positively correlated with adiponectin level. Multiple regression analysis showed that HOMA-IR was an independent factor influencing serum betatrophin levels. Further follow-up studies are needed to highlight whether and how increased betatrophin secretion play an important role in IR and carbohydrates metabolism in patients with PCOS.

Effects of sex steroids on women's health: implications for practitioners.

Androgen excess in women is manifested typically by clinical features that may include hirsutism, acne, central obesity, male-pattern baldness, upper torso widening, increased waist-to-hip ratio, clitoral hypertrophy, and deepening of the voice. The differential diagnosis includes androgen-producing ovarian and adrenal neoplasms, Cushing's syndrome, polycystic ovary syndrome, and the intake of exogenous androgens. Physicians treating patients for one symptom of androgen excess must be alert for other symptoms and signs. The cosmetic manifestations of androgen excess belie the serious health risks associated with this condition, including cardiovascular disease, intravascular thrombosis, and insulin resistance. Prompt clinical recognition of androgen excess, understanding of the androgen-related biochemical abnormalities underlying the risks associated with this condition, and implementation of risk modification can reduce the incidence of associated morbidity and mortality. An interdisciplinary approach to management is strongly recommended. Risk reduction strategies include correction of dyslipidemias, low-dose aspirin for primary prevention of myocardial infarction, maintenance of ideal weight, smoking cessation, exercise, use of oral contraceptives containing a low-androgenic progestin, and postmenopausal estrogen replacement. Combination oral contraceptives containing low-androgenic progestins are effective not only in reducing signs of androgen excess but also in potentially retarding the progression of long-term sequelae such as cardiovascular disease.

Human Parvovirus B19 (PVB19), the etiological agent of the fifth disease, is associated with a large spectrum of pathologies, among which is encephalitis. Since it has been detected from the central nervous system in children or in immunocompromised patients, its causative role in serious neurological manifestations is still unclear. Here we report the case of an 18-year-old healthy boy who developed encephalitis complicated by prolonged status epilepticus. The detection of PVB19 DNA in his serum and, subsequently, in his cerebrospinal fluid supports the hypothesis that this virus could potentially play a role in the pathogenesis of neurological complications. In addition, the detection of viral DNA and the presence of specific IgM and IgG antibodies in serum, together with clinical findings such as skin rash, support the presence of a disseminated viral infection. In the presence of neurological disorders, especially when there are no specific signs, but seizures and rash are present, it is important to search for PVB19 both in immunocompromised and immunocompetent patients. Moreover, the introduction of the PVB19 DNA test into diagnostic protocols of neuropathies, especially those undiagnosed, could clarify the etiological agent that otherwise could remain unrecognized.

Preterm birth is a global health issue that can induce lifelong medical sequela. Presently, at least one in ten newborns are born prematurely. At birth, preterm newborns exhibit higher levels of oxidative stress (OS) due to the inability to face the oxygen rich environment in which they are born into. Moreover, their immature respiratory, digestive, immune and antioxidant defense systems, as well as the potential numerous medical interventions following a preterm birth, such as oxygen resuscitation, nutrition, phototherapy and blood transfusion further contribute to high levels of OS. Although the acute effects seem well established, little is known regarding the long-term effects of preterm birth on OS. This matter is especially important given that chronically elevated OS levels may persist into adulthood and consequently contribute to the development of numerous non-communicable diseases observed in people born preterm such as diabetes, hypertension or lung disorders. The purpose of this review is to summarize the current knowledge regarding the consequences of preterm birth on OS levels from newborn to adulthood. In addition, the effects of physical activity and hypoxia, both known to disrupt redox balance, on OS modulation in preterm individuals are also explored. Copyright © 2018 The Authors.

Withania somnifera has been used in traditional medicine for a variety of neural disorders. Recently, chronic neurodegenerative conditions have been shown to benefit from treatment with this extract. To evaluate the action of this extract on traumatically injured neurons, the efficacy of W. somnifera root extract as a neuroprotective agent was examined in cultured model neurons exposed to an in vitro injury system designed to mimic mild traumatic brain injury (TBI). Neuronal health was evaluated by staining with annexin V (an early, apoptotic feature) and monitoring released lactate dehydrogenase activity (a terminal cell loss parameter). Potential mechanisms underlying the observed neuroprotection were examined. Additionally, morphological changes were monitored following injury and treatment. Although no differences were found in the expression of the antioxidant transcription factor nuclear factor erythroid 2-like 2 (Nrf2) or other Nrf2-related downstream components, significant changes were seen in apoptotic signaling. Treatment with the extract resulted in an increased length of neurites projecting from the neuronal cell body after injury. W. somnifera extract treatment also resulted in reduced cell death in the model neuron TBI system. The cell death factor Bax was involved (its expression was reduced 2-fold by the treatment) and injury-induced reduction in neurite lengths and numbers was reversed by the treatment. This all indicates that W. somnifera root extract was neuroprotective and could have therapeutic potential to target factors involved in secondary injury and long-term sequelae of mild TBI.

Pandemic obesity and the contagion of nutritional nonsense.

PubMed

Katz, David L

2003-01-01

The United States is the epicenter of an obesity pandemic. As more countries acculturate to a Western lifestyle, rates of obesity and its sequelae are rising steadily in both adults and children. In response, a variety of weight-loss diets emphasizing alternative distributions of macronutrient classes have been promoted with considerable success. Among the most popular is the so-called "Atkins Diet," in which carbohydrate restriction is touted as the key to weight loss. Despite claims, however, evidence that weight loss is enhanced by means other than caloric restriction is lacking. Also lacking is evidence that fad diets produce sustainable weight loss. Most important, fad diets generally ignore or refute what is known about fundamental associations between dietary pattern and human health. Cancer, cholera, and AIDS induce rapid weight loss, highlighting the potential incompatibility of weight loss by any means with health. Available data suggest that long-term weight loss is most consistently achieved by adherence to a fat-restricted diet abundant in grains, vegetables, and fruit, along with regular physical activity, a lifestyle notably conducive to the promotion of overall health. Fad diets, potential harms of which are well characterized, should be presumed "guilty" of incompatibility with human health until or unless proved otherwise; the burden of proof should reside with proponents. In the interim, the clinical and public health communities should work to empower individuals with knowledge needed to reconcile weight control with health promotion; support policies that mitigate obesogenic environmental conditions; and offer unified resistance to the contagion of dietary propaganda.

To comprehensively review the available evidence and existing consensus reports and guidelines regarding the pregnancy and reproductive implications of the mosquito-transmitted Zika virus (ZIKV) infection. A primary focus was to provide pertinent information to aid clinicians in the management of pregnancies at risk for, exposed to, or with confirmed ZIKV infection. An extensive literature review was performed using Pubmed. Practice guidelines and consensus reports were accessed from international, national, and professional organizations' websites. The clinical articles for ZIKV infection testing varied from case reports to small epidemiologic studies. A ZIKV epidemic has been declared in several countries in the Americas. Fifty-two travel-associated ZIKV infection cases have been reported throughout the USA (as of February 10, 2016). The consequences of congenital fetal/newborn ZIKV infection could potentially have devastating consequences including miscarriage, fetal death, and major anomalies such as microcephaly, brain and brain-stem defects, and long-term neurologic sequelae. While not definitive, current evidence suggests the existence of nonvector-borne transmission through sexual activity with an infected male partner. For women at risk for sexual transmission, condom use is advised, especially during pregnancy. While ZIKV infection appears to be a mild disease in the general population the potential consequences to the fetus and newborn could be profound. Management guidelines are currently evolving and will be significantly impacted as new evidence develops. It is therefore imperative that obstetric health-care providers keep abreast of this rapidly evolving information landscape that has so far characterized this outbreak.

Withania somnifera has been used in traditional medicine for a variety of neural disorders. Recently, chronic neurodegenerative conditions have been shown to benefit from treatment with this extract. To evaluate the action of this extract on traumatically injured neurons, the efficacy of W. somnifera root extract as a neuroprotective agent was examined in cultured model neurons exposed to an in vitro injury system designed to mimic mild traumatic brain injury (TBI). Neuronal health was evaluated by staining with annexin V (an early, apoptotic feature) and monitoring released lactate dehydrogenase activity (a terminal cell loss parameter). Potential mechanisms underlying the observed neuroprotection were examined. Additionally, morphological changes were monitored following injury and treatment. Although no differences were found in the expression of the antioxidant transcription factor nuclear factor erythroid 2-like 2 (Nrf2) or other Nrf2-related downstream components, significant changes were seen in apoptotic signaling.

The Feasibility and Acceptability of LISTEN for Loneliness

PubMed Central

Theeke, Laurie A.; Mallow, Jennifer A.; Barnes, Emily R.; Theeke, Elliott

2015-01-01

Purpose The purpose of this paper is to present the initial feasibility and acceptability of LISTEN (Loneliness Intervention using Story Theory to Enhance Nursing-sensitive outcomes), a new intervention for loneliness. Loneliness is a significant stressor and known contributor to multiple chronic health conditions in varied populations. In addition, loneliness is reported as predictive of functional decline and mortality in large samples of older adults from multiple cultures. Currently, there are no standard therapies recommended as effective treatments for loneliness. The paucity of interventions has limited the ability of healthcare providers to translate what we know about the problem of loneliness to active planning of clinical care that results in diminished loneliness. LISTEN was developed using the process for complex intervention development suggested by the Medical Research Council (MRC) [1] [2]. Methods Feasibility and acceptability of LISTEN were evaluated as the first objective of a longitudinal randomized trial which was set in a university based family medicine center in a rural southeastern community in Appalachia. Twenty-seven older adults [(24 women and 3 men, mean age: 75 (SD 7.50)] who were lonely, community-dwelling, and experiencing chronic illness, participated. Feasibility was evaluated by tracking recruitment efforts, enrollment, attendance to intervention sessions, attrition, and with feedback evaluations from study personnel. Acceptability was assessed using quantitative and qualitative evaluation data from participants. Results LISTEN was evaluated as feasible to deliver with no attrition and near perfect attendance. Participants ranked LISTEN as highly acceptable for diminishing loneliness with participants requesting a continuation of the program or development of additional sessions. Conclusions LISTEN is feasible to deliver in a primary healthcare setting and has the potential to diminish loneliness which could result in improvement of the long-term negative known sequelae of loneliness such as hypertension, depression, functional decline, and mortality. Feedback from study participants is being used to inform future trials of LISTEN with consideration for developing additional sessions. Longitudinal randomized trials are needed in varied populations to assess long-term health and healthcare system benefits of diminishing loneliness, and to assess the potential scalability of LISTEN as a reimbursable treatment for loneliness.

Abstract Background Quality of life (QoL) and long-term prognosis are frequently, and often severely, impaired in craniopharyngioma (CP) patients. Knowledge of risk factors for long-term outcome is important for optimization of treatment. Methods Overall survival (OS) and progression-free survival (PFS), body mass index (BMI), neuropsychological status (EORTCQLQ-C30, MFI-20), and psychosocial status were analyzed in 261 patients with childhood-onset CP diagnosed before 2000 and longitudinally observed in HIT-Endo. Results Twenty-year OS was lower (P = .006) in CP with hypothalamic involvement (HI) (n = 132; 0.84 ± 0.04) when compared with CP without HI (n = 82; 0.95 ± 0.04). OS was not related to degree of resection, sex, age at diagnosis, or year of diagnosis (before/after 1990). PFS (n = 168; 0.58 ± 0.05) was lower in younger patients (<5y at diagnosis) (n = 30; 0.39 ± 0.10) compared with patients aged 5–10 years (n = 66; 0.52 ± 0.08) and older than 10 years (n = 72; 0.77 ± 0.06) at diagnosis. PFS was not associated with HI, degree of resection, or sex. HI led to severe weight gain during the first 8–12 years of follow-up (median BMI increase: +4.59SD) compared with no HI (median increase: +1.20SD) (P = .00). During >12 years of follow-up, patients with HI presented no further increase in BMI. QoL in CP patients with HI was impaired by obesity, physical fatigue, reduced motivation, dyspnea, diarrhea, and nonoptimal psychosocial development. Conclusions OS and QoL are impaired by HI in long-term survivors of CP. HI is associated with severe obesity, which plateaus after 12 years. OS/PFS are not related to degree of resection, but gross-total resection should be avoided in cases of HI to prevent further hypothalamic damage, which exacerbates sequelae. PMID:25838139

Pediatric posterior fossa (PF) tumor survivors experience long-term motor deficits. Specific cerebrocerebellar connections may be involved in incidence and severity of motor dysfunction. We examined the relationship between long-term ataxia as well as fine motor function and alteration of differential cerebellar efferent and afferent pathways using diffusion tensor imaging (DTI) and tractography. DTI-based tractography was performed in 19 patients (10 pilocytic astrocytoma (PA) and 9 medulloblastoma patients (MB)) and 20 healthy peers. Efferent Cerebello-Thalamo-Cerebral (CTC) and afferent Cerebro-Ponto-Cerebellar (CPC) tracts were reconstructed and analyzed concerning fractional anisotropy (FA) and volumetric measurements. Clinical outcome was assessed with the International Cooperative Ataxia Rating Scale (ICARS). Kinematic parameters of fine motor function (speed, automation, variability, and pressure) were obtained by employing a digitizing graphic tablet. ICARS scores were significantly higher in MB patients than in PA patients. Poorer ICARS scores and impaired fine motor function correlated significantly with volume loss of CTC pathway in MB patients, but not in PA patients. Patients with pediatric post-operative cerebellar mutism syndrome showed higher loss of CTC pathway volume and were more atactic. CPC pathway volume was significantly reduced in PA patients, but not in MB patients. Neither relationship was observed between the CPC pathway and ICARS or fine motor function. There was no group difference of FA values between the patients and healthy peers. Reduced CTC pathway volumes in our cohorts were associated with severity of long-term ataxia and impaired fine motor function in survivors of MBs. We suggest that the CTC pathway seems to play a role in extent of ataxia and fine motor dysfunction after childhood cerebellar tumor treatment. DTI may be a useful tool to identify relevant structures of the CTC pathway and possibly avoid surgically induced long-term neurological sequelae.

2015-01-01

Multidisciplinary care, modern care management, and medical progress have brought significant gains in modern survival rates for children and adolescents with tumors of the musculoskeletal system. The surgical approach must rest on the consideration of the long-term orthopedic sequelae likely to be caused by the elected treatment (limb amputation versus limb conservation - reconstruction choices), as well as by adjuvant therapies, such as chemotherapy or radiotherapy. Complications due to allograft reconstructions (infections, fractures, pseudoarthritis) occur within the range of 0 to 36 months. After 36 months, allograft longevity is fair, but 10 years later, 60% of grafts are likely to have failed and been removed. Joint prostheses have overall survival rates of 75% over 10 years, and 52% over 20 years. As for allografts, infectious complications occur within the first few years, while later prosthetic replacements are mostly due to mechanical causes. Assessing the long-term evolution of biological reconstructions proves a lot more challenging, due to the lack of hindsight and available information, except for vascularized fibula grafts, which show good long-term results. Numerous medical reviews have been published that address the quality of life of children treated for malignant tumors of the musculoskeletal system. They mostly consist in comparative studies between limb conservation and limb amputation, and point to similar results overall. Such data must be taken into account when deciding on a treatment for a child or an adolescent: quality of life, the function of the affected limb, the probable need for re-operation all encourage to favor reconstructions whenever they are possible, as they come closest to normal anatomy. Too frequently, medical knowledge remains fragmented among multiple disciplines, because of the difficulty of organizing follow-up over the very long-term. Progress can only be achieved by setting-up multidisciplinary care pathways between pediatric surgeons and surgeons treating adult patients. Copyright © 2015 Société Française du Cancer.

Management of juvenile idiopathic arthritis: hitting the target.

Hinze, Claas; Gohar, Faekah; Foell, Dirk

2015-05-01

The treatment of juvenile idiopathic arthritis (JIA) is evolving. The growing number of effective drugs has led to successful treatment and prevention of long-term sequelae in most patients. Although patients with JIA frequently achieve lasting clinical remission, sustained remission off medication is still elusive for most. Treatment approaches vary substantially among paediatric rheumatologists owing to the inherent heterogeneity of JIA and, until recently, to the lack of accepted and well-evidenced guidelines. Furthermore, many pertinent questions related to patient management remain unanswered, in particular regarding treatment targets, and selection, intensity and sequence of initiation or withdrawal of therapy. Existing JIA guidelines and recommendations do not specify treat-to-target or tight control strategies, in contrast to adult rheumatology in which these approaches have been successful. The concepts of window of opportunity (early treatment to improve long-term outcomes) and immunological remission (abrogation of subclinical disease activity) are also fundamental when defining treatment methodologies. This Review explores the application of these concepts to JIA and their possible contribution to the development of future clinical guidelines or consensus treatment protocols. The article also discusses how diverse forms of standardized, guideline-led care and personalized treatment can be combined into a targeted, patient-centred approach to optimize management strategies for patients with JIA.

Role of Catheter-directed Thrombolysis in Management of Iliofemoral Deep Venous Thrombosis.

PubMed

Chen, James X; Sudheendra, Deepak; Stavropoulos, S William; Nadolski, Gregory J

2016-01-01

The treatment for iliofemoral deep venous thrombosis (DVT) is challenging, as the use of anticoagulation alone can be insufficient for restoring venous patency and thus lead to prolongation of acute symptoms and an increased risk of chronic complications, including venous insufficiency and postthrombotic syndrome (PTS). In these cases, earlier and more complete thrombus removal can ameliorate acute symptoms and reduce long-term sequelae. Endovascular therapies involving the use of pharmacologic, mechanical, and combined pharmacomechanical modalities have been developed to achieve these goals. The most frequently used of these techniques, catheter-directed thrombolysis (CDT), involves the infusion of a thrombolytic agent through a multiple-side-hole catheter placed within the thrombosed vein to achieve high local doses and thereby break down the clot while minimizing systemic thrombolytic agent exposure. Randomized controlled trial results have indicated decreased PTS rates and improved venous patency rates in patients treated with CDT compared with these rates in patients treated with anticoagulation. The use of newer pharmacomechanical techniques, as compared with conventional CDT, reduces procedural times and thrombolytic agent doses and is the subject of ongoing investigations. Endovascular thrombus removal techniques offer a means to improve venous valvular function and decrease the risk of debilitating long-term complications such as PTS and are a promising option for treating patients with iliofemoral DVT.

Treating acute seizures with benzodiazepines: does seizure duration matter?

PubMed

Naylor, David E

2014-10-01

Several clinical trials have shown improved seizure control and outcome by early initiation of treatment with benzodiazepines, before arrival in the emergency department and before intravenous access can be established. Here, evidence is provided and reviewed for rapid treatment of acute seizures in order to avoid the development of benzodiazepine pharmacoresistance and the emergence of self-sustaining status epilepticus. Alterations in the physiology, pharmacology, and postsynaptic level of GABA-A receptors can develop within minutes to an hour and hinder the ability of synaptic inhibition to stop seizures while also impairing the efficacy of GABAergic agents, such as benzodiazepines, to boost impaired inhibition. In addition, heightened excitatory transmission further exacerbates the inhibitory/excitatory balance and makes seizure control even more resistant to treatment. The acute increase in the surface expression of NMDA receptors during prolonged seizures also may cause excitotoxic injury, cell death, and other pathological expressions and re-arrangements of receptor subunits that all contribute to long-term sequelae such as cognitive impairment and chronic epilepsy. In conclusion, a short window of opportunity exists when seizures are maximally controlled by first-line benzodiazepine treatment. After that, multiple pathological mechanisms quickly become engaged that make seizures increasingly more difficult to control with high risk for long-term harm.

Patent ductus arteriosus (PDA) is one of the most common congenital heart defects. Once diagnosed, an immediate pharmacologic or invasive treatment should be performed. The purpose of this work was to evaluate the safety and efficacy of surgical PDA ligation in children using video-assisted thoracoscopic surgery (VATS) in comparison with a conventional muscle-sparing posterolateral thoracotomy technique (MSPLT). In this single-center, retrospective study 173 children qualified for surgical PDA closure were enrolled. Patients were divided according to their weight and type of surgery performed. The groups consisted of patients operated through thoracotomy (54%) or VATS (46%). Operative characteristics, cosmetic effect, postoperative complications and long-term survival were evaluated. Regardless of weight, fewer complications were noted in children after thoracoscopic clipping. Fifteen VATS patients required intraoperative conversion to thoracotomy; however, adverse sequelae were not observed. Aesthetics seemed to be the major complaint after conventional surgery. We did not observe any statistically significant differences in the long-term survival between both groups. Both techniques were shown to be safe and effective. Unsuccessfully performed thoracoscopic surgeries were safely converted to conventional thoracotomy. VATS, being a less invasive approach, leads to a better aesthetic effect and lower surgical complication rate. Copyright © 2016 Elsevier Inc. All rights reserved.

Depolarization-induced suppression of inhibition (DSI) is an endocannabinoid-mediated short-term plasticity mechanism that couples postsynaptic Ca2+ rises to decreased presynaptic GABA release. Whether the gain of this retrograde synaptic mechanism is subject to long-term modulation by glutamatergic excitatory inputs is not known. Here, we demonstrate that activity-dependent long-term DSI potentiation takes place in hippocampal slices after tetanic stimulation of Schaffer collateral synapses. This activity-dependent, long-term plasticity of endocannabinoid signaling was specific to GABAergic synapses, as it occurred without increases in the depolarization-induced suppression of excitation. Induction of tetanus-induced DSI potentiation in vitro required a complex pathway involving AMPA/kainate and metabotropic glutamate receptor as well as CB1 receptor activation. Because DSI potentiation has been suggested to play a role in persistent limbic hyperexcitability after prolonged seizures in the developing brain, we used these mechanistic insights into activity-dependent DSI potentiation to test whether interference with the induction of DSI potentiation prevents seizure-induced long-term hyperexcitability. The results showed that the in vitro, tetanus-induced DSI potentiation was occluded by previous in vivo fever-induced (febrile) seizures, indicating a common pathway. Accordingly, application of CB1 receptor antagonists during febrile seizures in vivo blocked the seizure-induced persistent DSI potentiation, abolished the seizure-induced upregulation of CB1 receptors, and prevented the emergence of long-term limbic hyperexcitability. These results reveal a new form of activity-dependent, long-term plasticity of endocannabinoid signaling at perisomatic GABAergic synapses, and demonstrate that blocking the induction of this plasticity abolishes the long-term effects of prolonged febrile seizures in the developing brain.

Is there a role for diet in ameliorating the reproductive sequelae associated with chronic low-grade inflammation in polycystic ovary syndrome and obesity?

PubMed

Riley, Joan K; Jungheim, Emily S

2016-09-01

A 2013 ASRM committee opinion titled "Optimizing natural fertility" stated that "there is little evidence that dietary variations such as vegetarian diets, low-fat diets, vitamin-enriched diets, antioxidants, or herbal remedies improve fertility …." However, there are emerging epidemiologic data demonstrating that certain components of the diet may influence reproductive health outcomes. Furthermore, translational work with human specimens and animal models lends biologic plausibility to the epidemiologic data, particularly in the context of female reproductive diseases associated with inflammation, including polycystic ovary syndrome (PCOS) and obesity. How to best apply these data clinically for improved reproductive outcomes remains to be determined. In this review, we outline a role for chronic inflammation in the reproductive sequelae of PCOS and obesity and we summarize epidemiologic and translational work demonstrating a potential role for diet in the regulation of inflammatory processes associated with these disorders. These studies identify areas for future research and potential clinical intervention in women affected by the reproductive sequelae of PCOS and obesity.

GSD Ia (von Gierke Disease, Glycogen Storage Disease Type Ia) is a devastating genetic disorder with long-term sequelae, such as non-alcoholic fatty liver disease and renal failure. Down-regulated autophagy is involved in the development of hepatic metabolic dysfunction in GSD Ia; however, the role of autophagy in the renal pathology is unknown. Here we show that autophagy is impaired and endoplasmic reticulum (ER) stress is increased in the kidneys of a mouse model of GSD Ia. Induction of autophagy by rapamycin also reduces this ER stress. Taken together, these results show an additional role for autophagy down-regulation in the pathogenesis of GSD Ia, and provide further justification for the use of autophagy modulators in GSD Ia.

2016-11-01

Injuries from sea urchin spines are commonly seen in coastal regions with high levels of participation in water activities. Although these injuries may seem minor, the consequences vary based on the location of the injury. Sea urchin spine injuries may cause arthritis and synovitis from spines in the joints. Nonjoint injuries have been reported, and dermatologic aspects of sea urchin spine injuries rarely have been discussed. We present a case of a patient with sea urchin spines embedded in the thigh who subsequently developed painful skin nodules. Tissue from the site of the injury demonstrated foreign-body type granulomas. Following the removal of the spines and granulomatous tissue, the patient experienced resolution of the nodules and associated pain. Extraction of sea urchin spines can attenuate the pain and decrease the likelihood of granuloma formation, infection, and long-term sequelae.

2006-12-01

Chronic ankle instability represents a typical sports injury which can mostly be seen in basketball, soccer, orienteering and other high risk sports. 20 to 40 % of the acute ankle sprains develop into chronic ankle instability. From a sports orthopaedic point of view, chronic ankle instability can be subdivided into a lateral, medial or a combination of both so called rotational ankle instability. From a pathophysiological point of view, chronic ankle instability can be either mechanical with a structural ligament lesion or functional with loss of the neuromuscular control. For the sports physician, the chronic ankle instability is a difficult entity as the diagnosis is usually complex and the therapy usually surgical. This review on chronic ankle instability addresses pathomechanism, diagnostics, indications for conservative and surgical treatments, and possible long-term sequelae, as ligamentous osteoarthritis.

Summary We sought to assess neurologists' interest in sports neurology and learn about their experience in treating sports-related neurologic conditions. A survey was sent to a random sample of American Academy of Neurology members. A majority of members (77%) see at least some patients with sports-related neurologic issues. Concussion is the most common sports-related condition neurologists treat. More than half of survey participants (63%) did not receive any formal or informal training in sports neurology. At least two-thirds of respondents think it is very important to address the following issues: developing evidence-based return-to-play guidelines, identifying risk factors for long-term cognitive-behavioral sequelae, and developing objective diagnostic criteria for concussion. Our findings provide an up-to-date view of the subspecialty of sports neurology and identify areas for future research. PMID:24790800

A pediatrician is asked by her local school board to help them decide whether to discontinue their high school football program. She reviews the available evidence on the risks of football and finds it hopelessly contradictory. Some scholars claim that football is clearly more dangerous than other sports. Others suggest that the risks of football are comparable to other sports, such as lacrosse, ice hockey, or soccer. She finds very little data on the long-term sequelae of concussions. She sees claims that good coaching and a school culture that prioritizes the health of athletes over winning can reduce morbidity from sports injuries. In this paper, 3 experts also review the evidence about sports risks and discuss what is known and not known about the science and the ethics of high school football.

Fever in Children: Should it be Treated?

PubMed Central

Habbick, Brian F.

1988-01-01

Fever, which is the regulation of body temperature at an elevated level, must be differentiated from hyperthermia. The pathogenesis of fever involves exogenous pyrogens acting on macrophages/monocytes to produce the endogenous pyrogen, interleukin-1, which acts on the thermoregulatory centre and also has important effects on the body's immune responses to infection. Fever by itself is rarely harmful, and there is no evidence that febrile seizures produce long-term sequelae. On the other hand, fever may be part of the body's innate protection against infection. The main reason for treating a fever in a child is to relieve discomfort. Acetaminophen should be the drug of first choice in treatment, and sponging, if used at all, should be employed only after acetaminophen has been given first. Education of parents about fever management can be helpful. PMID:21253180

1997-01-01

Neurobehavioural deficits are commonly reported following treatment for childhood cancers. This study examined the impact of cranial irradiation (CRT) and chemotherapy in children, aiming to identify factors detrimental to long-term outcome. The study compared survivors of acute lymphoblastic leukemia (ALL), treated with CRT and chemotherapy (CRT group: n = 100), survivors of cancers treated with chemotherapy only (n = 50) and healthy controls (n = 100) for intelligence, academic achievement, information processing, learning, and executive function. CRT and chemotherapy in combination were associated with reduced intelligence, educational skill, immediate memory, processing speed, and executive function. Children treated with chemotherapy alone exhibited subtle information processing deficits. Within the CRT group, younger age at treatment was predictive of deficits in non-verbal ability, educational skills and executive functions. High dose CRT was associated with poorer information processing and lower arithmetic ability.

Tick-borne encephalitis.

Tick-borne encephalitis (TBE) is a zoonotic arbovirus infection endemic to Russia and Eastern and Central Europe. Despite being a common and serious life-threatening disease for which a mass vaccination program was implemented in Austria, there is only limited reference to this disease in the English-language literature. TBE is transmitted to humans usually by the bite of a tick (either Ixodes persulcatus or Ixodes ricinus); occasionally, cases occur following consumption of infected unpasteurized milk. Transmission is seasonal and occurs in spring and summer, particularly in rural areas favored by the vector. TBE is a serious cause of acute central nervous system disease, which may result in death or long-term neurological sequelae. Effective vaccines are available in a few countries. The risk for travelers of acquiring TBE is increasing with the recent rise in tourism to areas of endemicity during spring and summer.

Disturbed sleep is one of the most common complaints following traumatic brain injury (TBI) and worsens morbidity and long-term sequelae. Further, sleep and TBI share neurophysiologic underpinnings with direct relevance to recovery from TBI. As such, disturbed sleep and clinical sleep disorders represent modifiable treatment targets to improve outcomes in TBI. This paper presents key findings from a national working group on sleep and TBI, with a specific focus on the testing and development of sleep-related therapeutic interventions for mild TBI (mTBI). First, mTBI and sleep physiology are briefly reviewed. Next, essential empirical and clinical questions and knowledge gaps are addressed. Finally, actionable recommendations are offered to guide active and efficient collaboration between academic, industry, and governmental stakeholders.

The purpose of our study was to present descriptive findings of ocular abnormalities in vision screening examinations of abused and neglected children. We compared the prevalence and the nature of eye diseases and refractive error between abused and neglected boys staying at the Hathaway Home, a residential facility for abused children, and boys from neighboring Boys and Girls clubs. The children in the study received vision screening examinations through the UCLA Mobile Eye Clinic following a standard format. Clinical data were analyzed by chi-square test. The children with a history of abuse demonstrated significantly higher prevalence of myopia, astigmatism, and external eye disorders. Our study suggests that children with a history of abuse may be at higher risk for visual impairment. These visual impairments may be the long-term sequelae of child abuse.

Recent trends in the treatment of testosterone deficiency syndrome.

Testosterone deficiency syndrome (TDS) is defined as a clinical and biochemical syndrome associated with advancing age and is characterized by typical symptoms and deficiency in serum testosterone levels. TDS is a result of the interaction of hypothalamo-pituitary and testicular factors. Now, treatment of TDS with testosterone is still controversial due to a lack of large, controlled clinical trials on efficacy. The risks of treatment with testosterone appear to be minimal, although long-term studies on the safety of testosterone therapy are lacking. The aim of the therapy is to establish a physiological concentration of serum testosterone in order to correct the androgen deficiency, relieve its symptoms and prevent long-term sequelae. All of the available products, despite their varying pharmacodynamic and pharmacokinetic profiles, are able to reach this goal. Newer testosterone patches seem not to cause severe skin irritation. Testosterone gels minimize the skin irritation while providing flexibility in dosing and a low discontinuation rate. Oral testosterone undecanoate (TU) is free of liver toxicity. Recent formulation of oral TU markedly increased shelf-live, a major drawback in the older preparation. Producing swings in testosterone levels rising rapidly to the supraphysiological range is not the case with the new injectable long-acting preparation of TU. To be able to rapidly react and stop treatment in cases where side-effects and contraindications are detected, the short-acting transdermal and oral delivery modes have certain advantages. However, there is no evidence that the use of an injectable long-acting TU in men with TDS has limitations in clinical application for this reason. The use of dehydroepiandrosterone is still controversial because of a lack of well designed long-term trials, although some recent studies suggest positive effects on various body systems. Only a few studies have been carried out to investigate the effect of hCG (human chorionic gonadotropin) in TDS with some positive results on various body systems.

Iron deficiency (ID) during early life causes long-lasting detrimental cognitive sequelae, many of which are linked to alterations in hippocampus function, dopamine synthesis, and the modulation of dopaminergic circuitry by the hippocampus. These same features have been implicated in the origins of schizophrenia, a neuropsychiatric disorder with significant cognitive impairments. Deficits in sensorimotor gating represent a reliable endophenotype of schizophrenia that can be measured by prepulse inhibition (PPI) of the acoustic startle reflex. Using two rodent model systems, we investigated the influence of early-life ID on PPI in adulthood. To isolate the role of hippocampal iron in PPI, our mouse model utilized a timed (embryonic day 18.5), hippocampus-specific knockout of Slc11a2, a gene coding an important regulator of cellular iron uptake, the divalent metal transport type 1 protein (DMT-1). Our second model used a classic rat dietary-based global ID during gestation, a condition that closely mimics human gestational ID anemia (IDA). Both models exhibited impaired PPI in adulthood. Furthermore, our DMT-1 knockout model displayed reduced long-term potentiation (LTP) and elevated paired pulse facilitation (PPF), electrophysiological results consistent with previous findings in the IDA rat model. These results, in combination with previous findings demonstrating impaired hippocampus functioning and altered dopaminergic and glutamatergic neurotransmission, suggest that iron availability within the hippocampus is critical for the neurodevelopmental processes underlying sensorimotor gating. Ultimately, evidence of reduced PPI in both of our models may offer insights into the roles of fetal ID and the hippocampus in the pathophysiology of schizophrenia. PMID:23733517

Temporal variations in the potential hydrological performance of extensive green roof systems

2018-03-01

Existing literature provides contradictory information about variation in potential green roof hydrological performance over time. This study has evaluated a long-term hydrological monitoring record from a series of extensive green roof test beds to identify long-term evolutions and sub-annual (seasonal) variations in potential hydrological performance. Monitoring of nine differently-configured extensive green roof test beds took place over a period of 6 years in Sheffield, UK. Long-term evolutions and sub-annual trends in maximum potential retention performance were identified through physical monitoring of substrate field capacity over time. An independent evaluation of temporal variations in detention performance was undertaken through the fitting of reservoir-routing model parameters. Aggregation of the resulting retention and detention variations permitted the prediction of extensive green roof hydrological performance in response to a 1-in-30-year 1-h summer design storm for Sheffield, UK, which facilitated the comparison of multi and sub-annual hydrological performance variations. Sub-annual (seasonal) variation was found to be significantly greater than long-term evolution. Potential retention performance increased by up to 12% after 5-years, whilst the maximum sub-annual variation in potential retention was 27%. For vegetated roof configurations, a 4% long-term improvement was observed for detention performance, compared to a maximum 63% sub-annual variation. Consistent long-term reductions in detention performance were observed in unvegetated roof configurations, with a non-standard expanded-clay substrate experiencing a 45% reduction in peak attenuation over 5-years. Conventional roof configurations exhibit stable long-term hydrological performance, but are nonetheless subject to sub-annual variation.

Teenage childbearing. An adaptive strategy for the socioeconomically disadvantaged or a strategy for adapting to socioeconomic disadvantage?

PubMed

Stevens-Simon, C; Lowy, R

1995-08-01

To examine the relation between childbearing and educational and vocational achievements of American females high school students. Articles published in English during the past decade about the educational, vocational, and socioeconomic sequelae of childbearing among female high school students. Articles that did not contain data about the relation between adolescent childbearing and educational and vocational achievement were excluded. Most females who begin childbearing during adolescence obtain less schooling and poorer-paying jobs than do females who postpone childbearing. The reasons for this are elusive. Differences in the family and cultural backgrounds of early (high school-age) and later (18 years and older) childbearers explain some but not all of the association between early childbearing and educational and vocational underachievement. The effect of childbearing preferences on the educational and vocational achievements of teenagers has not been studied adequately. Lack of concrete information could result in underestimation of the effect of early childbearing on the socioeconomic well-being of young Americans, and create the impression that adolescent pregnancy is an adaptive response to urban poverty. As much as the long-term socioeconomic sequelae of adolescent childbearing reflect factors that influence the judgments young people make about the costs and benefits of contraception and parenthood, adolescent childbearing is a means of adapting to urban poverty. Thus postponing adolescent conceptions and parenthood may have a less important effect on the socioeconomic well-being of young Americans than expected.

Predicting the child-rearing practices of mothers sexually abused in childhood.

Ruscio, A M

2001-03-01

Although empirical investigations have established a relationship between childhood sexual abuse and numerous long-term consequences, surprisingly little research has addressed the possible effects of childhood victimization on the later child-rearing practices of adult survivors. The present study examined hypothesized predictors of three parenting styles among adult survivors of sexual abuse as compared with adult children of alcoholic parents. Forty-five clinical outpatients completed a questionnaire battery assessing experiences of childhood abuse, current economic and social resources, and parenting attitudes and practices. The child-rearing practices of participants were compared with those reported by a community sample of 717 mothers. Additional analyses examined the extent to which sexual abuse and its adult sequelae predicted the parenting behaviors reported by the present sample. Both sexual abuse survivors and children of alcoholics reported significantly higher rates of permissive parenting practices than mothers in the community sample. Multiple regression analyses further revealed unique relationships between sexual abuse and parenting, over and above the variance explained by physical abuse, current socioeconomic status, and the experience of growing up in an alcoholic home. Mothers' sexual abuse severity, social support satisfaction, and dysfunctional parenting attitudes moderated several of these relationships. The present findings suggest that sexual abuse and its adult sequelae may have negative consequences for the parenting practices of survivors, particularly for survivors' ability to provide their children with appropriate structure, consistent discipline, and clear behavioral expectations. Implications for the psychosocial development of survivors' children are discussed.

The sequelae and behaviour in children several years after an episode of bacterial meningitis were studied. All children in Sweden aged 0-4 years with bacterial meningitis between 1987 and 1989 caused by Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis were identified. After exclusion of 16 children who died, 12 with severe concomitant diseases, ten with severe neurological damage obvious already at discharge from hospital and 34 with unknown address, questionnaires were sent to the parents of the remaining 463 children The nearest-age siblings were used as a comparison group. The questionnaires included questions concerning general health, schooling, motor function, speech, hearing and behaviour (inattention, hyperactivity and impulsiveness). The children were 6-14 years old when the questionnaires were completed. Questionnaires were completed for 304 pairs of patients and siblings and for 154 patients without siblings. The majority of post-meningitic children were healthy and attended normal school but they had more hearing impairment, headaches and problems with balance than their siblings. When the distributions of answers regarding behaviour were compared, the post-meningitic children had significantly more symptoms in the fields of inattention, hyperactivity and impulsiveness than their siblings. Except for hearing impairment, severe sequelae after bacterial meningitis which are not discovered at discharge do not appear later. Children who appear well after bacterial meningitis have more non-specific symptoms like headache, and more signs and symptoms indicating inattention, hyperactivity and impulsiveness than their siblings.

We evaluated therapy complications in 19 beta-thalassemia major patients (mean age from 3 years/5 months and 1 years/6 months) who were followed at II Pediatric Department-University of Bari. 3 out of 19 patients underwent allogenic BMT from matched related donor; 2 out of 19 underwent splenectomy. All of them were receiving hypertransfusion therapy and continuous chelation with DFO. In all patients we performed physical examination, laboratory assays, cardiac and endocrinologic function tests, serum HBV-HCV-HIV antibodies, otoscopy and audiometric test, fundus oculi, skeletal x-ray. 1 out of 19 patients, who was under 15, had a slight dilatation of left ventricle and arythmia. All patients were HBsAb positive. 4/19 patients were HCV Ab positive (ELISA test) with an increase in ALT-AST serum levels since at least 6 months. In 3 of them we assessed RIBA test, always positive. 3 of them underwent liver biopsy (1 iron overload 2 chronic active hepatitis). All patients were HIV Ab negative. 4/15 patients revealed low GH levels after Arginina test. 13 pre-pubescent patients had normal results with GNRH test but lower results after FSH test. 1 pubescent patient had gonadotropic hypophyseal deficit. 4 patients had subclinic hypothiroidism. We couldn't find any sequelas in bone-eyes-ears. Hypertransfusion therapy, chelation, profilaxis of infections improved length and quality of life in thalassemic patients. Hypogonadotropic hypogonadism remains a serious sequela and we think it needs to be treated.

Acute hydrogen sulfide–induced neuropathology and neurological sequelae: challenges for translational neuroprotective research

Hydrogen sulfide (H2S), the gas with the odor of rotten eggs, was formally discovered in 1777, over 239 years ago. For many years, it was considered an environmental pollutant and a health concern only in occupational settings. Recently, however, it was discovered that H2S is produced endogenously and plays critical physiological roles as a gasotransmitter. Although at low physiological concentrations it is physiologically beneficial, exposure to high concentrations of H2S is known to cause brain damage, leading to neurodegeneration and long‐term neurological sequelae or death. Neurological sequelae include motor, behavioral, and cognitive deficits, which are incapacitating. Currently, there are concerns about accidental or malicious acute mass civilian exposure to H2S. There is a major unmet need for an ideal neuroprotective treatment, for use in the field, in the event of mass civilian exposure to high H2S concentrations. This review focuses on the neuropathology of high acute H2S exposure, knowledge gaps, and the challenges associated with development of effective neuroprotective therapy to counteract H2S‐induced neurodegeneration.

Congenital HCMV infection is a leading infectious cause of long-term neurodevelopmental sequelae. Infection of newborn mice with mouse cytomegalovirus (MCMV) intraperitoneally is a well-established model of congenital human cytomegalovirus infection, which best recapitulates the hematogenous route of virus spread to brain and subsequent pathology. Here, we used this model to investigate the role, dynamics, and phenotype of CD8 + T cells in the brain following infection of newborn mice. We show that CD8 + T cells infiltrate the brain and form a pool of tissue-resident memory T cells (T RM cells) that persist for lifetime. Adoptively transferred virus-specific CD8 + T cells provide protection against primary MCMV infection in newborn mice, reduce brain pathology, and remain in the brain as T RM cells. Brain CD8 + T RM cells were long-lived, slowly proliferating cells able to respond to local challenge infection. Importantly, brain CD8 + T RM cells controlled latent MCMV and their depletion resulted in virus reactivation and enhanced inflammation in brain. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The Development of LISTEN: A Novel Intervention for Loneliness

PubMed Central

Theeke, Laurie A.; Mallow, Jennifer A.

2015-01-01

Purpose The purpose of this paper is to present the development of LISTEN (Loneliness Intervention using Story Theory to Enhance Nursing-sensitive outcomes), a new intervention for loneliness. Methods LISTEN was developed using the Medical Research Council (MRC) framework for intervention development. Extensive literature review revealed that belonging, relating, placing in community, challenges, and meanings of coping were concepts significant to loneliness. Past interventions were limited but it was determined from a recent meta-analysis that enhanced effectiveness might result from interventions that targeted the poorly adapted cognitive processes of loneliness. These processes include social undesirability, stigma, and negative thoughts about self in relation to others. LISTEN is designed to be delivered in a determined logical sequence of 5 sessions, each focusing on the concepts relevant to loneliness as derived from the literature. For each session, intervention delivery is guided by the concepts from story theory (including intentional dialogue, nurse as listener, examination of self in relation to others and community, synthesizing concerns and patterns, and identifying messages) and the principles of cognitive restructuring (self-assessment of maladaptive cognitions, emotions, and behaviors, identifying challenges of changing, reconceptualization of self, new skill acquisition through group interaction, and identifying patterns of meaning in loneliness). Results LISTEN is developed and the first randomized trial is complete with a sample of 27 lonely, chronically ill, community dwelling, and older adults. LISTEN was evaluated as feasible to deliver by the study team and acceptable for significantly diminishing loneliness by participants of the LISTEN groups who were compared to attention control groups (p < 0.5). Conclusions LISTEN has the potential to enhance health by diminishing loneliness which could result in improving the long-term negative known sequelae of loneliness. Future longitudinal randomized trials are needed in varied populations to assess long term health and healthcare system benefit of using LISTEN to treat loneliness. PMID:26229740

To examine the association between sepsis and the long-term risk of seizures. We conducted a retrospective population-based cohort study using administrative claims data from all emergency department visits and hospitalizations at nonfederal acute care hospitals in California, Florida, and New York from 2005 to 2013. Using previously validated diagnosis codes, we identified all adult patients hospitalized with sepsis. Our outcome was any emergency department visit or hospitalization for seizure. Poisson regression and demographic data were used to calculate age-, sex-, and race-standardized incidence rate ratios (IRR). To confirm our findings, we used a matched cohort of hospitalized patients without sepsis for comparison and additionally assessed claims data from a nationally representative 5% sample of Medicare beneficiaries. We identified 842,735 patients with sepsis. The annual incidence of seizure was 1.29% (95% confidence interval [CI] 1.27%-1.30%) in patients with sepsis vs 0.16% (95% CI 0.16%-0.16%) in the general population (IRR 4.98; 95% CI 4.92-5.04). A secondary analysis using matched hospitalized patients confirmed these findings (IRR 4.33; 95% CI 4.13-4.55), as did a separate analysis of Medicare beneficiaries, in whom we found a similar strength of association (IRR 2.72; 95% CI 2.60-2.83), as we did in patients ≥65 years of age in our primary statewide data (IRR 2.83; 95% CI 2.78-2.88). We found that survivors of sepsis faced a significantly higher long-term risk of seizures than both the general population and other hospitalized patients. Our findings suggest that sepsis is associated with pathways that lead to permanent neurologic sequelae. © 2017 American Academy of Neurology.

Cardiac morbidity is an important late effect in long-term childhood cancer survivors (CCS) treated with cardiotoxic agents or radiotherapy (RT) on the chest. However, there is limited data on the long-term cardiac sequelae in CCS who only received cranial RT. We hypothesized that cranial RT might negatively influence cardiac structure and function. We studied 13 CCS [mean age 30.8 (18.1-39.3) years, 7 males] who received RT only on the head for a cranial tumor and 36 age- and sex-matched healthy sibling controls. Echocardiographic follow-up was performed at median 21.7 (12.6-30.8) years after diagnosis. CCS had lower indexed diastolic LV volumes [56.0 (31.4-68.3) vs. 60.5 (41.9-94.3) mL/m(2), p = 0.024]. CCS also had reduced LV systolic and diastolic function, reflected by lower systolic LV myocardial velocities (5.3 ± 0.9 vs. 7.1 ± 1.7 cm/s, p = 0.001) and longitudinal deformation (- 17.3 ± 3.1 vs. - 20.7 ± 2.0%, p < 0.001), as well as lower diastolic LV myocardial velocities (- 10.7 ± 1.7 vs. - 12.2 ± 1.5 cm/s, p = 0.006) and deformation speed (1.1 ± 0.3 vs. 1.5 ± 0.2 1/s, p = 0.005). Additionally, in CCS insulin-like growth factor levels [15.4 (9.2-34.6) vs. 24.4 (14.8-55.5) nmol/L, p = 0.007] were lower. Cranial RT in CCS is associated with smaller cardiac volumes and reduced systolic and diastolic LV function. This off target effect of RT might be related to lower insulin-like growth factor levels.

The aim of this study was to analyse the long-term functional, subjective, and psychological results after single-digit replantation. Thirty cases of digital replantation (14 thumbs, 12 index fingers, 2 middle fingers, 1 ring finger, and 1 little finger) in 30 patients (7 females and 23 males) with a mean age of 44.2 years (20-65 years) were evaluated at the end of a mean follow-up time of 36 months (19-50 months). The active range of motion of joints, grip and pinch strength, cutaneous sensibility, upper-extremity functioning, and subjective satisfaction were determined using the Disability of Arm, Shoulder, and Hand (DASH) questionnaire and the Michigan Hand Outcomes questionnaire (MHQ). Psychological sequelae, including depression, anxiety, and posttraumatic stress disorder (PTSD), were assessed. A correlation analysis among variables was also performed. The mean score for the DASH questionnaire was 6.6 (range: 0-39.2). The symptom of cold intolerance occurred in 53% of the patients. Two patients were diagnosed with depression, and only one patient exhibited PTSD. The DASH score had a good statistical correlation with total grip strength, pinch grip strength, and static two-point discrimination (S-2PD) (P < 0.05). Several aspects of the MHQ were also statistically relevant to some or all of the three objective results. Furthermore, the grip strength showed significant correlation with DASH and most aspects of the MHQ in multivariate logistic regression analysis (P < 0.05). Total grip strength is the most important factor positively related to subjective outcomes. The incidence rates of psychological symptoms after digit replantation are very low at long-term follow-up.

2016-01-01

We report the results of the visual evoked potentials (VEP) examination in patients after severe poisoning by methanol. The group of 47 patients (38 males and 9 females) was assembled out of persons who survived an outbreak of poisoning by the methanol adulterated alcohol beverages, which happened in the Czech Republic in 2012-2013. The visual evoked potentials examination was performed using monocular checkerboard pattern-reversal stimulation. Two criteria of abnormality were chosen: missing evoked response, and wave P1 latency > 117 ms. Non-parametric statistical methods (median, range, and the median test) were used to analyze factors influencing the VEP abnormality. The visual evoked potential was abnormal in 20 patients (43%), 5 of them had normal visual acuity on the Snellen chart. The VEP abnormality did not correlate significantly with initial serum concentrations of methanol, formic acid or lactate; however, it showed statistically significant inverse relation to the initial serum pH: the subgroup with the abnormal VEP had significantly lower median pH in comparison with the subgroup with the normal VEP (7.16 vs. 7.34, p = 0.04). The abnormality was not related to chronic alcohol abuse. The visual evoked potentials examination appeared sensitive enough to detected even subclinical impairment of the optic system. Metabolic acidosis is likely to be the key factor related to the development of visual damage induced by methanol. The examination performed with a delay of 1-9 months after the poisoning documented the situation relatively early after the event. It is considered as a baseline for the planned long-term follow-up of the patients, which will make it possible to assess the dynamics of the observed changes, their reversibility, and the occurrence of potential late sequelae.

Exploring views on long term rehabilitation for people with stroke in a developing country: findings from focus group discussions

PubMed Central

2014-01-01

Background The importance of long term rehabilitation for people with stroke is increasingly evident, yet it is not known whether such services can be materialised in countries with limited community resources. In this study, we explored the perception of rehabilitation professionals and people with stroke towards long term stroke rehabilitation services and potential approaches to enable provision of these services. Views from providers and users are important in ensuring whatever strategies developed for long term stroke rehabilitations are feasible and acceptable. Methods Focus group discussions were conducted involving 15 rehabilitation professionals and eight long term stroke survivors. All recorded conversations were transcribed verbatim and analysed using the principles of qualitative research. Results Both groups agreed that people with stroke may benefit from more rehabilitation compared to the amount of rehabilitation services presently provided. Views regarding the unavailability of long term rehabilitation services due to multi-factorial barriers were recognised. The groups also highlighted the urgent need for the establishment of community-based stroke rehabilitation centres. Family-assisted home therapy was viewed as a potential approach to continued rehabilitation for long term stroke survivors, given careful planning to overcome several family-related issues. Conclusions Barriers to the provision of long term stroke rehabilitation services are multi-factorial. Establishment of community-based stroke rehabilitation centres and training family members to conduct home-based therapy are two potential strategies to enable the continuation of rehabilitation for long term stroke survivors.

Nutritional management of patients with gastric cancer (GC) represents a challenge. This review provides an overview of the present evidence on nutritional support in patients with GC undergoing surgery as well as in those with advanced disease. For patients undergoing surgery, the preoperative nutritional condition directly affects postoperative prognosis, overall survival and disease-specific survival. Perioperative nutritional support enriched with immune-stimulating nutrients reduces overall complications and hospital stay but not mortality after major elective gastrointestinal surgery. Early enteral nutrition after surgery improves early and long-term postoperative nutritional status and reduces the length of hospitalization as well. Vitamin B12 and iron deficiency are common metabolic sequelae after gastrectomy and warrant appropriate replacement. In malnourished patients with advanced GC, short-term home complementary parenteral nutrition improves the quality of life, nutritional status and functional status. Total home parenteral nutrition represents the only modality of caloric intake for patients with advanced GC who are unable to take oral or enteral nutrition. Early evaluations of nutritional status and nutritional support represent key aspects in the management of GC patients with both operable and advanced disease.

Gut microbiota: puppeteer of the host juvenile growth.

PubMed

Schwarzer, Martin

2018-05-01

This review focuses on the recent discoveries about the impact of intestinal microbiota on mammalian host juvenile growth. Intestinal microbiota is a powerful modulator of many facets of multicellular host's physiology. Recent results from human field studies and animal research have clearly shown that not only the nutrition, but also the intestinal microbiota impacts host postnatal growth kinetics. Absence of microbiome leads to stunted growth in mammalian gnotobiotic models and changes in the composition of the intestinal microbiota can impact the postnatal growth kinetics both positively and negatively under normal nutritional conditions as well as in undernutrition. Strikingly, specific bacterial strains are able to interact with GH/IGF-1 somatotropic axis activity, thus directly impacting host juvenile development. Intestinal microbiota dictates the pace of host postnatal growth. This newly described role envisages that therapy with specific bacterial strains, together with re-nutritional strategies, might successfully alleviate the long-term sequelae of undernutrition during childhood in humans.

Thiamine deficiency also alters principally hippocampal- and frontal cortical-dependent neurochemistry; moreover in WKS patients, important pathological damage to the diencephalon can occur. In fact, the amnesic syndrome typical for WKS is mainly due to the damage in the diencephalic-hippocampal circuitry, including thalamic nuclei and mammillary bodies. The loss of cholinergic cells in the basal forebrain region results in decreased cholinergic input to the hippocampus and the cortex and reduced choline acetyltransferase and acetylcholinesterase activities and function, as well as in acetylcholine receptor downregulation within these brain regions. In this narrative review, we will focus on the neurochemical, neuroanatomical, and neuropsychological studies shedding light on the effects of thiamine deficiency in experimental models and in humans.

Using risk assessment in periodontics.

Woodman, Alan J

2014-08-01

Risk assessment has become a regular feature in both dental practice and society as a whole, and principles used to assess risk in society are similar to those used in a clinical setting. Although the concept of risk assessment as a prognostic indicator for periodontal disease incidence and activity is well established in the management of periodontitis, the use of risk assessment to manage the practical treatment of periodontitis and its sequelae appears to have less foundation. A simple system of initial risk assessment - building on the use of the Basic Periodontal Examination (BPE), clinical, medical and social factors - is described, linked to protocols for delivering care suited to general dental practice and stressing the role of long-term supportive care. The risks of not treating the patient are considered, together with the possible causes of failure, and the problems of successful treatment are illustrated by the practical management of post-treatment recession.

Pathology and differential diagnosis of chronic, noninfectious gastritis.

PubMed

Polydorides, Alexandros D

2014-03-01

The histologic finding of chronic inflammation in an endoscopic mucosal biopsy of the stomach (chronic gastritis) is very common and usually reflects the presence of Helicobacter pylori infection. However, infectious organisms are not always present in biopsy material, and some cases of chronic gastritis do not result from H. pylori infection. Thus, the differential diagnosis of this finding is an important one for pathologists to keep in mind. This review presents the three most common and clinically significant causes of chronic, noninfectious gastritis, namely, autoimmune atrophic gastritis, lymphocytic gastritis, and gastric involvement in the setting of inflammatory bowel disease, especially Crohn disease. For each entity, a brief discussion of its etiology and pathogenesis, a review of the clinical and endoscopic features, and a description of the microscopic findings are presented in the context of the differential diagnosis of chronic gastritis with emphasis on helpful histopathologic hints and long-term sequelae.

2011-01-01

West Nile virus (WNV), from the Flaviviridae family, is a re-emerging zoonotic pathogen of medical importance. In humans, WNV infection may cause life-threatening meningoencephalitis or long-term neurologic sequelae. WNV is transmitted by Culex spp mosquitoes and both the arthropod vector and the mammalian host are equipped with antiviral innate immune mechanisms sharing a common phylogeny. As far as the current evidence is able to demonstrate, mosquitoes primarily rely on RNA interference, Toll, Imd and JAK-STAT signaling pathways for limiting viral infection, while mammals are provided with these and other more complex antiviral mechanisms involving antiviral effectors, inflammatory mediators, and cellular responses triggered by highly specialized pathogen detection mechanisms that often resemble their invertebrate ancestry. This mini-review summarizes our current understanding of how the innate immune systems of the vector and the mammalian host react to WNV infection and shape its pathogenesis. PMID:21790942

The Burn Wound Microenvironment

Rose, Lloyd F.; Chan, Rodney K.

2016-01-01

Significance: While the survival rate of the severely burned patient has improved significantly, relatively little progress has been made in treatment or prevention of burn-induced long-term sequelae, such as contraction and fibrosis. Recent Advances: Our knowledge of the molecular pathways involved in burn wounds has increased dramatically, and technological advances now allow large-scale genomic studies, providing a global view of wound healing processes. Critical Issues: Translating findings from a large number of in vitro and preclinical animal studies into clinical practice represents a gap in our understanding, and the failures of a number of clinical trials suggest that targeting single pathways or cytokines may not be the best approach. Significant opportunities for improvement exist. Future Directions: Study of the underlying molecular influences of burn wound healing progression will undoubtedly continue as an active research focus. Increasing our knowledge of these processes will identify additional therapeutic targets, supporting informed clinical studies that translate into clinical relevance and practice. PMID:26989577

2016-01-01

Congenital heart disease is the most common congenital defect. During childhood, survival is generally good but, in adulthood, late complications are not uncommon. Abnormal autonomic control in children with congenital heart disease may contribute considerably to the pathophysiology of these long term sequelae. This narrative review of 34 studies aims to summarize current knowledge on function of the autonomic nervous system in children with a congenital heart defect. Large scale studies that measure both branches of the nervous system for prolonged periods of time in well-defined patient cohorts in various phases of childhood and adolescence are currently lacking. Pending such studies, there is not yet a good grasp on the extent and direction of sympathetic and parasympathetic autonomic function in pediatric congenital heart disease. Longitudinal studies in homogenous patient groups linking autonomic nervous system function and clinical outcome are warranted. PMID:29367565

Emerging pharmacotherapy for cancer patients with cognitive dysfunction

PubMed Central

2013-01-01

Advances in the diagnosis and multi-modality treatment of cancer have increased survival rates for many cancer types leading to an increasing load of long-term sequelae of therapy, including that of cognitive dysfunction. The cytotoxic nature of chemotherapeutic agents may also reduce neurogenesis, a key component of the physiology of memory and cognition, with ramifications for the patient’s mood and other cognition disorders. Similarly radiotherapy employed as a therapeutic or prophylactic tool in the treatment of primary or metastatic disease may significantly affect cognition. A number of emerging pharmacotherapies are under investigation for the treatment of cognitive dysfunction experienced by cancer patients. Recent data from clinical trials is reviewed involving the stimulants modafinil and methylphenidate, mood stabiliser lithium, anti-Alzheimer’s drugs memantine and donepezil, as well as other agents which are currently being explored within dementia, animal, and cell culture models to evaluate their use in treating cognitive dysfunction.

In a prospective cohort study of the long-term sequelae of induced abortion, a comparison is made between a group of 6418 women who had an induced abortion (cases) and a control group of 8059 women recruited with an unplanned pregnancy which was not terminated with an induced abortion (controls). The present paper reports on 729 cases and 1754 controls who had a post-recruitment pregnancy. In general, prior induced abortion had no material effect on the rate of pregnancy-related morbidity, nor on the rate of congenital abnormalities and neonatal death in the offspring. There was, however, a significant difference in two specific conditions. In the post-index pregnancy in the cases there was an increased relative risk (RR 2.26) of the occurrence of urinary tract infection and a decreased risk (RR 0.25) of pregnancy-related anaemia.

Background. The current West Africa Ebola virus disease (EVD) outbreak has resulted in multiple individuals being medically evacuated to other countries for clinical management. Methods. We report two patients who were transported from West Africa to the United States for treatment of EVD. Both patients received aggressive supportive care measures, as well as an investigational therapeutic (TKM-100802) and convalescent plasma. Results. While one patient experienced critical illness with multi-organ failure requiring mechanical ventilation and renal replacement therapy, both patients recovered without serious long-term sequelae to date. Conclusions. It is unclear what role the experimental drug and convalescent plasma had in the recovery of these patients. Prospective clinical trials are needed to delineate the role of investigational therapies in the care of patients with EVD. PMID:25904375

The pathoanatomy and arthroscopic management of femoroacetabular impingement

PubMed Central

Tibor, L. M.; Leunig, M.

2012-01-01

Femoroacetabular impingement (FAI) causes pain and chondrolabral damage via mechanical overload during movement of the hip. It is caused by many different types of pathoanatomy, including the cam ‘bump’, decreased head–neck offset, acetabular retroversion, global acetabular overcoverage, prominent anterior–inferior iliac spine, slipped capital femoral epiphysis, and the sequelae of childhood Perthes’ disease. Both evolutionary and developmental factors may cause FAI. Prevalence studies show that anatomic variations that cause FAI are common in the asymptomatic population. Young athletes may be predisposed to FAI because of the stress on the physis during development. Other factors, including the soft tissues, may also influence symptoms and chondrolabral damage. FAI and the resultant chondrolabral pathology are often treated arthroscopically. Although the results are favourable, morphologies can be complex, patient expectations are high and the surgery is challenging. The long-term outcomes of hip arthroscopy are still forthcoming and it is unknown if treatment of FAI will prevent arthrosis. PMID:23610655

Obesity and its health sequelae affect a significant portion of children in the United States. Yet, the current gold-standard family-based behavioral weight-loss treatments are only effective for one-third of children long-term. Therefore, we developed iROC (Intervention for Regulation of Cues) to specifically target a method to decrease overeating in overweight children, based on learning theory, to inform and enhance interventions targeting diet and obesity in youth. This study will rigorously test extinction processes as a method of decreasing physiological and psychological responses to food cues in overweight and obese children. Through exposing children to their highly craved foods, and 'training the brain and body' to decrease overeating, we are hoping to produce longer-lasting weight loss or weight-gain prevention over time.

Sexual violence against women: Understanding cross-cultural intersections

Kalra, Gurvinder; Bhugra, Dinesh

2013-01-01

Interpersonal violence whether it is sexual or nonsexual, remains a major problem in large parts of the world. Sexual violence against children and women brings with it long-term sequelae, both psychiatrically and socially. Apart from sexual gratification itself, sexual violence against women is often a result of unequal power equations both real and perceived between men and women and is also strongly influenced by cultural factors and values. Within sociocentric and ego-centric cultures, the roles and representations of genders, and attitudes toward sexual violence differ. Cultures which are described as feminist, provide equal power to both men and women. Sexual violence is likely to occur more commonly in cultures that foster beliefs of perceived male superiority and social and cultural inferiority of women. Although culture is an important factor to understand sexual violence in its entirety, we need to look at, as well as beyond cultural structures, their strengths and weaknesses. PMID:24082244

Management of chronic lateral ankle instability in military service members.

PubMed

Orr, Justin D; Robbins, Justin; Waterman, Brian R

2014-10-01

Chronic lateral ankle instability is a condition frequently encountered by orthopedic surgeons treating highly active patient populations, particularly military service members. Providers treating military service members must have a high index of suspicion for this condition when signs and symptoms of functional or mechanical instability exist. Stress testing and ankle MRI, although not definitive in sensitivity for detecting instability or other concomitant injuries, should be considered during the treatment decision-making process. Appropriate nonoperative treatment should be attempted initially; however, when nonoperative treatment fails, surgical management is warranted to prevent untoward long-term sequelae. Proper surgical treatment and subsequent postoperative management are at the discretion of the individual surgeon but must account for the concomitant diseases frequently associated with chronic lateral ankle instability. Low recurrence of lateral instability can be achieved even in high-demand military patient populations with a focused treatment plan. Published by Elsevier Inc.

The Executive Committee of the International Ankle Consortium presents this 2016 position paper with recommendations for information implementation and continued research based on the paradigm that lateral ankle sprain (LAS), and the development of chronic ankle instability (CAI), serve as a conduit to a significant global healthcare burden. We intend our recommendations to serve as a mechanism to promote efforts to improve prevention and early management of LAS. We believe this will reduce the prevalence of CAI and associated sequelae that have led to the broader public health burdens of decreased physical activity and early onset ankle joint post-traumatic osteoarthritis. Ultimately, this can contribute to healthier lifestyles and promotion of physical activity. Published by the BMJ Publishing Group Limited.

Stewart, Donna E; Vigod, Simone; Riazantseva, Ekaterina

2016-01-01

Intimate partner violence (IPV) is a global public health and human rights problem that causes physical, sexual and psychological harms to men and women. IPV includes physical aggression, sexual coercion, psychological abuse and/or controlling behaviours perpetrated by a current or previous intimate partner in a heterosexual or same-sex relationship. IPV affects both men and women, but women are disproportionately affected with nearly one third reporting IPV during their lifetime. Physical and sexual harms from IPV include injury, increased risk for sexually transmitted diseases, pregnancy complications and sometimes death. Psychological consequences include depression, anxiety, posttraumatic stress disorder, substance abuse, impulsivity and suicidality and non-specific physical complaints thought to be related to the traumatic nature and chronic stress of IPV. Children who witness IPV are also negatively impacted in the short and long term. This paper reviews prevalence, risk factors, adverse effects and current evidence-based mental health treatment advice for IPV victims.

Delayed onset of neuropsychiatric symptoms after apparent recovery from acute carbon monoxide (CO) poisoning has been described as delayed neuropsychiatric sequelae (DNS). No previous study has determined whether early use of diffusion-weighted magnetic resonance imaging (DWI) can predict which patients will develop DNS in the acute CO poisoning. This retrospective observational study was performed on adult patients with acute CO poisoning consecutively treated over a 17-month period. All included patients with acute CO poisoning underwent DWI to evaluate brain injury within 72 h after CO exposure. DWI was evaluated as follows: (1) presence of pathology, (2) number of pathologies, (3) asymmetry, and (4) location of pathology. Patients were divided into two groups. The DNS group was composed of patients with delayed sequelae, while the non-DNS group included patients with no sequelae. A total of 102 patients with acute CO poisoning were finally enrolled in this study. DNS developed in 10 patients (9.8%). Between the DNS group and the non-DNS group, presence of pathology on DWI and initial Glasgow Coma Scale (GCS) showed significant difference. There was also a statistical difference between the non-DNS group and DNS group in terms of CO exposure time, troponin I, rhabdomyolysis, acute kidney injury, and pneumonia. The presence of pathology in DWI and initial GCS (cutoff: <12) at the emergency department served as an early predictors of DNS.

GluA2-dependent AMPA receptor endocytosis and the decay of early and late long-term potentiation: possible mechanisms for forgetting of short- and long-term memories.

2014-01-05

The molecular processes involved in establishing long-term potentiation (LTP) have been characterized well, but the decay of early and late LTP (E-LTP and L-LTP) is poorly understood. We review recent advances in describing the mechanisms involved in maintaining LTP and homeostatic plasticity. We discuss how these phenomena could relate to processes that might underpin the loss of synaptic potentiation over time, and how they might contribute to the forgetting of short-term and long-term memories. We propose that homeostatic downscaling mediates the loss of E-LTP, and that metaplastic parameters determine the decay rate of L-LTP, while both processes require the activity-dependent removal of postsynaptic GluA2-containing AMPA receptors.

Long-term potentiation and long-term depression: a clinical perspective

PubMed Central

Bliss, Timothy V.P.; Cooke, Sam F

2011-01-01

Long-term potentiation and long-term depression are enduring changes in synaptic strength, induced by specific patterns of synaptic activity, that have received much attention as cellular models of information storage in the central nervous system. Work in a number of brain regions, from the spinal cord to the cerebral cortex, and in many animal species, ranging from invertebrates to humans, has demonstrated a reliable capacity for chemical synapses to undergo lasting changes in efficacy in response to a variety of induction protocols. In addition to their physiological relevance, long-term potentiation and depression may have important clinical applications. A growing insight into the molecular mechanisms underlying these processes, and technological advances in non-invasive manipulation of brain activity, now puts us at the threshold of harnessing long-term potentiation and depression and other forms of synaptic, cellular and circuit plasticity to manipulate synaptic strength in the human nervous system. Drugs may be used to erase or treat pathological synaptic states and non-invasive stimulation devices may be used to artificially induce synaptic plasticity to ameliorate conditions arising from disrupted synaptic drive. These approaches hold promise for the treatment of a variety of neurological conditions, including neuropathic pain, epilepsy, depression, amblyopia, tinnitus and stroke. PMID:21779718

Prenatal drug exposure: infant and toddler outcomes.

This manuscript provides an overview of the current scientific literature on the impact of maternal drug use, specifically opioids and cocaine, during pregnancy on the acute and long-term outcomes of infants and toddlers from birth through age 3 years. Emphasis with regard to opioids is placed on heroin and opioid substitutes used to treat opioid addiction, including methadone, which has long been regarded as the standard of care in pregnancy, and buprenorphine, which is increasingly being investigated and prescribed as an alternative to methadone. Controlled studies comparing methadone at high and low doses, as well as those comparing methadone with buprenorphine, are highlighted and the diagnosis and management of neonatal abstinence syndrome is discussed. Over the past two decades, attention of the scientific and lay communities has also been focused on the potential adverse effects of cocaine and crack cocaine, especially during the height of the cocaine epidemic in the United States. Herein, the findings are summarized from prospective studies comparing cocaine-exposed with non-cocaine-exposed infants and toddlers with respect to anthropometric growth, infant neurobehavior, visual and auditory function, and cognitive, motor, and language development. The potentially stigmatizing label of the so-called "crack baby" preceded the evidence now accumulating from well-designed prospective investigations that have revealed less severe sequelae in the majority of prenatally exposed infants than originally anticipated. In contrast to opioids, which may produce neonatal abstinence syndrome and infant neurobehavioral deficits, prenatal cocaine exposure appears to be associated with what has been described as statistically significant but subtle decrements in neurobehavioral, cognitive, and language function, especially when viewed in the context of other exposures and the caregiving environment which may mediate or moderate the effects. Whether these early findings may herald more significant learning and behavioral problems during school-age and adolescence when the child is inevitably confronted with increasing social and academic challenges is the subject of ongoing longitudinal research.

DNA Methylation as a Biomarker for Preeclampsia

DOE Office of Scientific and Technical Information (OSTI.GOV)

Anderson, Cindy M.; Ralph, Jody L.; Wright, Michelle L.

Background: Preeclampsia contributes significantly to pregnancy-associated morbidity and mortality as well as future risk of cardiovascular disease in mother and offspring, and preeclampsia in offspring. The lack of reliable methods for early detection limits the opportunities for prevention, diagnosis, and timely treatment. Purpose: The purpose of this study was to explore distinct DNA methylation patterns associated with preeclampsia in both maternal cells and fetal-derived tissue that represent potential biomarkers to predict future preeclampsia and inheritance in children. Method: A convenience sample of nulliparous women (N = 55) in the first trimester of pregnancy was recruited for this prospective study. Genome-widemore » DNA methylation was quantified in first-trimester maternal peripheral white blood cells and placental chorionic tissue from normotensive women and those with preeclampsia (n = 6/group). Results: Late-onset preeclampsia developed in 12.7% of women. Significant differences in DNA methylation were identified in 207 individual linked cytosine and guanine (CpG) sites in maternal white blood cells collected in the first trimester (132 sites with gain and 75 sites with loss of methylation), which were common to approximately 75% of the differentially methylated CpG sites identified in chorionic tissue of fetal origin. Conclusion: This study is the first to identify maternal epigenetic targets and common targets in fetal-derived tissue that represent putative biomarkers for early detection and heritable risk of preeclampsia. Findings may pave the way for diagnosis of preeclampsia prior to its clinical presentation and acute damaging effects, and the potential for prevention of the detrimental long-term sequelae.« less

Chronic stress impairs learning and memory in humans and rodents and disrupts long-term potentiation (LTP) in animal models. These effects are associated with structural changes in hippocampal neurons, including reduced dendritic arborization. Unlike the generally reversible effects of chronic stress on adult rat hippocampus, we have previously found that the effects of early-life stress endure and worsen during adulthood, yet the mechanisms for these clinically important sequelae are poorly understood. Stress promotes secretion of the neuropeptide corticotropin-releasing hormone (CRH) from hippocampal interneurons, activating receptors (CRF1) located on pyramidal cell dendrites. Additionally, chronic CRF1 occupancy negatively affects dendritic arborization in mouse organotypic slice cultures, similar to the pattern observed in middle-aged, early-stressed (CES) rats. Here we found that CRH-expression is augmented in hippocampus of middle-aged CES rats, and then tested if the morphological defects and poor memory performance in these animals involve excessive activation of CRF1 receptors. Central or peripheral administration of a CRF1 blocker following the stress period improved memory performance of CES rats in novel object recognition tests and in the Morris water maze. Consonant with these effects, the antagonist also prevented dendritic atrophy and LTP attenuation in CA1 Schaffer collateral synapses. Together, these data suggest that persistently elevated hippocampal CRH-CRF1 interaction contributes importantly to the structural and cognitive impairments associated with early-life stress. Reducing CRF1 occupancy post-hoc normalized hippocampal function during middle-age, thus offering potential mechanism-based therapeutic interventions for children affected by chronic stress.

Synaptic plasticity in the medial vestibular nuclei: role of glutamate receptors and retrograde messengers in rat brainstem slices.

Grassi, S; Pettorossi, V E

2001-08-01

The analysis of cellular-molecular events mediating synaptic plasticity within vestibular nuclei is an attempt to explain the mechanisms underlying vestibular plasticity phenomena. The present review is meant to illustrate the main results, obtained in vitro, on the mechanisms underlying long-term changes in synaptic strength within the medial vestibular nuclei. The synaptic plasticity phenomena taking place at the level of vestibular nuclei could be useful for adapting and consolidating the efficacy of vestibular neuron responsiveness to environmental requirements, as during visuo-vestibular recalibration and vestibular compensation. Following a general introduction on the most salient features of vestibular compensation and visuo-vestibular adaptation, which are two plastic events involving neuronal circuitry within the medial vestibular nuclei, the second and third sections describe the results from rat brainstem slice studies, demonstrating the possibility to induce long-term potentiation and depression in the medial vestibular nuclei, following high frequency stimulation of the primary vestibular afferents. In particular the mechanisms sustaining the induction and expression of vestibular long-term potentiation and depression, such as the role of various glutamate receptors and retrograde messengers have been described. The relevant role of the interaction between the platelet-activating factor, acting as a retrograde messenger, and the presynaptic metabotropic glutamate receptors, in determining the full expression of vestibular long-term potentiation is also underlined. In addition, the mechanisms involved in vestibular long-term potentiation have been compared with those leading to long-term potentiation in the hippocampus to emphasize the most significant differences emerging from vestibular studies. The fourth part, describes recent results demonstrating the essential role of nitric oxide, another retrograde messenger, in the induction of vestibular potentiation. Finally the fifth part suggests the possible functional significance of different action times of the two retrograde messengers and metabotropic glutamate receptors, which are involved in mediating the presynaptic mechanism sustaining vestibular long-term potentiation.

Traumatic brain injury (TBI) is a leading cause of disability and death and survivors often suffer from long-lasting motor impairment, cognitive deficits, anxiety disorders and epilepsy. Few experimental studies have investigated long-term sequelae after TBI and relations between behavioral changes and neural activity patterns remain elusive. We examined these issues in a murine model of TBI combining histology, behavioral analyses and single-photon emission computed tomography (SPECT) imaging of regional cerebral blood flow (CBF) as a proxy for neural activity. Adult C57Bl/6N mice were subjected to unilateral cortical impact injury and investigated at early (15-57 days after lesion, dal) and late (184-225 dal) post-traumatic time points. TBI caused pronounced tissue loss of the parietal cortex and subcortical structures and enduring neurological deficits. Marked perilesional astro- and microgliosis was found at 57 dal and declined at 225 dal. Motor and gait pattern deficits occurred at early time points after TBI and improved over the time. In contrast, impaired performance in the Morris water maze test and decreased anxiety-like behavior persisted together with an increased susceptibility to pentylenetetrazole-induced seizures suggesting alterations in neural activity patterns. Accordingly, SPECT imaging of CBF indicated asymmetric hemispheric baseline neural activity patterns. In the ipsilateral hemisphere, increased baseline neural activity was found in the amygdala. In the contralateral hemisphere, homotopic to the structural brain damage, the hippocampus and distinct cortex regions displayed increased baseline neural activity. Thus, regionally elevated CBF along with behavioral alterations indicate that increased neural activity is critically involved in the long-lasting consequences of TBI.

Young children with brain tumors are at high risk of developing late sequelae after curative radiotherapy. A retrospective study was undertaken to determine the frequency and severity of neurological deficits, endocrine dysfunction, and intellectual disabilities. One hundred and fifty-six children age {ge} 3 years were treated between 1952 and 1986 with radiotherapy. Of the 57 survivors, 47 had surgery, 12 chemotherapy and 24 children received cranio-spinal radiotherapy. Late radiation side effects were assessed with a clinical examination, blood tests and an interview. The median follow-up was 13 years and the actuarial survival at 5 and 10 years was 49% andmore » 44%, respectively. No, or only a mild, handicap was noted in 24 patients, while 21 had moderately severe and 16 severe disabilities. Children with supratentorial tumors had more abnormal neurological findings compared to those with infratentorial malignancies (p<0.001). Eighty percent of children had endocrine abnormalities, which were more marked in children with parasellar tumors (p<0.001). Twenty-one children were mentally retarded. In a multivariate analysis epilepsy emerged as the only significant variable independently associated with poor cognitive function. Long-term morbidity was found to be disabling in 58% of the surviving children. These findings encourage the development of treatment strategies designed to reduce toxity. 34 refs., 3 figs., 5 tabs.« less

Unintended pregnancy among adolescents (10-19years) and young women (20-24years) is a global public health problem. Adolescents face challenges in accessing safe abortion care. To determine, via a systematic data review, whether abortion care for adolescent and young women differs clinically from that for older women. In a comprehensive data review, the Cochrane Central Register of Controlled Trials, MEDLINE, and POPLINE databases were searched from the earliest data entered until November 2012. Randomized controlled trials and observational studies comparing effectiveness, safety, acceptability, and long-term sequelae of abortion care between adolescent/young women and older women were identified. Two reviewers independently extracted data, and the Cochrane guidelines and Newcastle-Ottawa Scale were used for quality assessment. In total, there were 25 studies including 346 000 women undergoing first- and second-trimester medical abortion, vacuum aspiration, or dilation and evacuation. Effectiveness and overall complications were similar among age groups. However, younger women had an increased risk for cervical laceration and a decreased risk of uterine perforation and mortality. Satisfaction and long-term depression were similar between age groups. Except for less uptake of intrauterine devices among adolescents, age did not affect post-abortion contraception. Evidence from various healthcare systems indicates that abortion is safe and efficacious among adolescent and young women. Clinical services should promote access to safe abortion for adolescents. © 2013.

Urogenital tuberculosis (TB) is common in developing countries. We present our experience of surgically managed cases of genitourinary TB (GUTB). We retrospectively reviewed 60 cases GUTB who underwent surgery at our center from January 2003 to January 2010. Mode of presentation, organ involvement, investigation, surgical treatment and follow-up were studied. There were 38 males and 22 females with a mean age of 32.5 years. The most common symptom was irritative voiding symptoms. The most common organ involved was bladder in 33 cases, and next most common was kidney in 30 cases. Preoperative bacteriologic diagnosis was confirmed in only 19 cases. A total of 66 procedures were performed as some patients needed more than one procedure. These included 35 ablative procedures and 31 reconstructive procedures. All the patients were followed-up with renal function test (RFT) at 3, 6 and 12 months. The intravenous urography and diethylenetriamine pentaacetic acid scan were performed at 3 months when indicated. Then the patients were followed with RFT and ultrasonography 6 monthly for 3 years and then annual RFT. Many patients of urogenital TB present late with cicatrisation sequelae. Multidrug chemotherapy with judicious surgery as and when indicated is the ideal treatment. The results of reconstructive surgery are good and should be done when possible. Rigorous and long term follow-up is necessary in patients undergoing reconstructive surgery.

To examine long-term outcome after tick-borne encephalitis (TBE) in children. In this population-based cohort, 55 children with TBE with central nervous system involvement infected during 2004-2008 were evaluated 2-7 years later using the Rivermead post-concussion symptoms questionnaire (n = 42) and the Behavior Rating Inventory of Executive Functioning for parents and teachers (n = 32, n = 22, respectively). General cognitive ability was investigated in a subgroup (n = 20) using the Wechsler Intelligence Scale for Children, 4th edition. At long-term follow-up, two-thirds of the children experienced residual problems, the main complaints being cognitive problems, headache, fatigue, and irritability. More than one-third of the children were reported by parents or teachers to have problems with executive functioning on the Behavior Rating Inventory of Executive Functioning, mainly in areas involving initiating and organizing activities and working memory. Children who underwent Wechsler Intelligence Scale for Children, 4th edition testing had a significantly lower working memory index compared with reference norms. A large proportion of children experience an incomplete recovery after TBE with central nervous system involvement. Cognitive problems in areas of executive function and working memory are the most prevalent. Even if mortality and severe sequelae are low in children after TBE, all children should be followed after TBE to detect cognitive deficits. Copyright © 2013 Mosby, Inc. All rights reserved.

The study was made to evaluate the long-term physical and psychosocial changes after high-dose therapy and autologous bone marrow or peripheral stem transplantation for recurrent lymphoid malignancies. Patients who had undergone high dose therapy and autologous bone marrow or peripheral stem cell transplantation for recurrent lymphoid malignancies at least 1 year previously were contacted by phone interview regarding their status after the transplant. The patients' comments were confirmed by checking medical records when possible. Fifty patients who had undergone transplantation at the University of Nebraska Medical Center at least 1 year before the interview were available for interview and willing to answer questions. After transplant, many patients noticed temporary changes in their appearance, which usually returned to normal within 1 year. Few patients reported remarkable cardiovascular, gastrointestinal, or pulmonary changes after transplantation. However, up to one-third of the patients reported changes in sexual function or desire. The most common infectious problem after transplant was Herpes zoster, which occurred in 25% of the patients. Overall, the patients had a positive outlook after high-dose therapy and transplantation, with most being able to return to work and enjoy a normal life style. Ninety-six percent of the patients stated that they would be willing to undergo high-dose therapy and transplantation again under the same circumstances.

Enhancing patient-provider communication for long-term post-stroke spasticity management.

Stroke is a major public health concern, with estimated 16 million people worldwide experiencing first-time strokes each year, a number that is expected to rise. Two-thirds of those experiencing a stroke are younger than 70 years of age. Stroke is a leading cause of disability in adults as a result of major sequelae that include spasticity, cognitive impairment, paresis, and depression. Disabling spasticity, defined as spasticity severe enough to require intervention, occurs in 4% of stroke survivors within 1 year of first-time stroke. The aim of this report is to focus instead on a discussion of patient-provider communication, and its role in post-stroke spasticity (PSS) rehabilitation within the context of patient-centered health care. A discussion based on a review of the literature, mainly since 2000. Problems within communication are identified and suggestion to enhance communication are proposed thus improving patient-centered goal setting/goal achievement for the effective management of spasticity rehabilitation. These are as follows: (i) involving family members, (ii) educating patients and family members on stroke and rehabilitation, and (iii) establishing a common definition for long-term goals. Increased communication among physicians, patients, and payers may bridge some of the gaps and increase the effectiveness of PSS rehabilitation and management. © 2013 John Wiley & Sons A/S.

Ocular trauma is common in birds of prey presented to wildlife clinics and rehabilitation centers. Enucleation is the procedure most commonly described for treatment of end-stage ocular disease or chronically painful eyes in birds; however, there are several disadvantages and risks to this procedure. While evisceration has been suggested as an alternative, it has not been described for multiple cases or with long-term follow-up data in birds of prey. This report details an evisceration technique performed in 5 captive birds of prey of 4 different species (1 eastern screech owl [Megascops asio], 1 great horned owl [Bubo virginianus], 2 red-tailed hawks [Buteo jamaicensis], and 1 bald eagle [Haliaeetus leucocephalus]) with long-term follow-up information. In addition, this report describes 14 cases of free-living owls of 3 different species (1 great horned owl, 4 barred owls [Strix varia], and 9 eastern screech owls) on which this technique was performed from 2004 to 2011 and which were subsequently released to the wild. Because of the limited risk of complications and the less-severe disruption of facial symmetry, which may be particularly important in owls that are candidates for release to the wild, evisceration should be considered over enucleation in birds of prey that require surgical intervention for the management of severe sequelae to ocular trauma.

Adjunctive 830 nm light-emitting diode therapy can improve the results following aesthetic procedures.

Aggressive, or even minimally aggressive, aesthetic interventions are almost inevitably followed by such events as discomfort, erythema, edema and hematoma formation which could lengthen patient downtime and represent a major problem to the surgeon. Recently, low level light therapy with light-emitting diodes (LED-LLLT) at 830 nm has attracted attention in wound healing indications for its anti-inflammatory effects and control of erythema, edema and bruising. The wavelength of 830 nm offers deep penetration into living biological tissue, including bone. A new-generation of 830 nm LEDs, based on those developed in the NASA Space Medicine Laboratory, has enabled the construction of planar array-based LED-LLLT systems with clinically useful irradiances. Irradiation with 830 nm energy has been shown in vitro and in vivo to increase the action potential of epidermal and dermal cells significantly. The response of the inflammatory stage cells is enhanced both in terms of function and trophic factor release, and fibroblasts demonstrate superior collagenesis and elastinogenesis. A growing body of clinical evidence is showing that applying 830 nm LED-LLLT as soon as possible post-procedure, both invasive and noninvasive, successfully hastens the resolution of sequelae associated with patient downtime in addition to significantly speeding up frank wound healing. This article reviews that evidence, and attempts to show that 830 nm LED-LLLT delivers swift resolution of postoperative sequelae, minimizes downtime and enhances patient satisfaction.

Phenylketonuria (PKU) is caused by phenylalanine hydroxylase (PAH) deficiency that results in phenylalanine (Phe) accumulation. Pegvaliase, PEGylated recombinant Anabaena variabilis phenylalanine ammonia lyase (PAL), converts Phe to trans-cinnamic acid and ammonia, and is a potential enzyme substitution therapy to lower blood Phe in adults with PKU. Two Phase 3 studies, PRISM-1 and PRISM-2, evaluated the efficacy and safety of pegvaliase treatment using an induction, titration, and maintenance dosing regimen in adults with PKU. In PRISM-1, pegvaliase-naïve participants with blood Phe >600 μmol/L were randomized 1:1 to a maintenance dose of 20 mg/day or 40 mg/day of pegvaliase. Participants in PRISM-1 continued pegvaliase treatment in PRISM-2, a 4-part clinical trial that includes an ongoing, open-label, long-term extension study of pegvaliase doses of 5 mg/day to 60 mg/day. Of 261 participants who received pegvaliase treatment, 72.0% and 32.6% reached ≥12 months and ≥ 24 months of study treatment, respectively, and 65% are still actively receiving treatment. Mean (SD) blood Phe was 1232.7 (386.4) μmol/L at baseline, 564.5 (531.2) μmol/L at 12 months, and 311.4 (427) μmol/L at 24 months, a decrease from baseline of 51.1% and 68.7%, respectively. Within 24 months, 68.4% of participants achieved blood Phe ≤600 μmol/L, 60.7% of participants achieved blood Phe ≤360 μmol/L, below the upper limit recommended in the American College of Medical Genetics and Genomics PKU management guidelines, and 51.2% achieved blood Phe ≤120 μmol/L, below the upper limit of normal in the unaffected population. Improvements in neuropsychiatric outcomes were associated with reductions in blood Phe and were sustained with long-term pegvaliase treatment. Adverse events (AEs) were more frequent in the first 6 months of exposure (early treatment phase) than after 6 months of exposure (late treatment phase); 99% of AEs were mild or moderate in severity and 96% resolved without dose interruption or reduction. The most common AEs were arthralgia (70.5%), injection-site reaction (62.1%), injection-site erythema (47.9%), and headache (47.1%). Acute systemic hypersensitivity events consistent with clinical National Institute of Allergy and Infectious Diseases and the Food Allergy and Anaphylaxis Network anaphylaxis criteria were observed in 12 participants (17 events); of these, 6 participants remained on treatment. Acute systemic hypersensitivity events including potential events of anaphylaxis were not associated with immunoglobulin E, and all events resolved without sequelae. Results from the PRISM Phase 3 program support the efficacy of pegvaliase for the treatment of adults with PKU, with a manageable safety profile in most participants. The PRISM-2 extension study will continue to assess the long-term effects of pegvaliase treatment. Copyright © 2018 The Authors. Published by Elsevier Inc. All rights reserved.

Cultured epithelial autografts (CEAs) produced from a small, healthy skin biopsy represent a lifesaving surgical technique in cases of full-thickness skin burn covering >50% of total body surface area. CEAs also present numerous drawbacks, among them the use of animal proteins and cells, the high fragility of keratinocyte sheets, and the immaturity of the dermal-epidermal junction, leading to heavy cosmetic and functional sequelae. To overcome these weaknesses, we developed a human plasma-based epidermal substitute (hPBES) for epidermal coverage in cases of massive burn, as an alternative to traditional CEA, and set up critical quality controls for preclinical and clinical studies. In this study, phenotypical analyses in conjunction with functional assays (clonal analysis, long-term culture, or in vivo graft) showed that our new substitute fulfills the biological requirements for epidermal regeneration. hPBES keratinocytes showed high potential for cell proliferation and subsequent differentiation similar to healthy skin compared with a well-known reference material, as ascertained by a combination of quality controls. This work highlights the importance of integrating relevant multiparameter quality controls into the bioengineering of new skin substitutes before they reach clinical development. Significance This work involves the development of a new bioengineered epidermal substitute with pertinent functional quality controls. The novelty of this work is based on this quality approach.

Our group has conducted several Internet investigations into the biobehavioural effects of self-reported recreational use of MDMA (3,4-methylenedioxymethamphetamine or Ecstasy) and other psychosocial drugs. Here we report a new study examining the relationship between self-reported Ecstasy use and traces of MDMA found in hair samples. In a laboratory setting, 49 undergraduate volunteers performed an Internet-based assessment which included mood scales and the University of East London Drug Use Questionnaire, which asks for history and current drug use. They also provided a hair sample for determination of exposure to MDMA over the previous month. Self-report of Ecstasy use and presence in hair samples were consistent (p < 0.00001). Both subjective and objective measures predicted lower self-reported ratings of happiness and higher self-reported stress. Self-reported Ecstasy use, but not presence in hair, was also associated with decreased tension. Different psychoactive drugs can influence long-term mood and cognition in complex and dynamically interactive ways. Here we have shown a good correspondence between self-report and objective assessment of exposure to MDMA. These data suggest that the Internet has potentially high utility as a useful medium to complement traditional laboratory studies into the sequelae of recreational drug use. Copyright © 2010 S.

Evolving Perspectives on Lyme Borreliosis in Canada

2012-01-01

With cases now documented in every province, Lyme borreliosis (LB) is emerging as a serious public health risk in Canada. Controversy over the contribution of LB to the burden of chronic disease is maintained by difficulty in capturing accurate Canadian statistics, especially early clinical cases of LB. The use of dogs as sentinel species demon-strates that potential contact with Borrelia burgdorferi spirochetes, as detected by C6 peptide, extends across the country. Dissemination of infected ticks by migratory birds and rapid establishment of significant levels of infection have been well described. Canadian public health response has focused on identification of established populations of the tick vectors, Ixodes scapularis and I. pacificus, on the assumption that these are the only important vectors of the disease across Canada. Strains of B. burgdorferi circulating in Canada and the full range of their reservoir species and coinfections remain to be explored. Ongoing surveys and historical records demonstrate that Borrelia-positive Ixodes species are regu-larly present in regions of Canada that have previously been considered to be outside of the ranges of these species in re-cent modeling efforts. We present data demonstrating that human cases of LB are found across the nation. Consequently, physician education and better early diagnoses are needed to prevent long term sequelae. An international perspective will be paramount for developing improved Canadian guidelines that recognize the complexity and diversity of Lyme borreliosis. PMID:23091570

Long term reshaping of language, sensory, and motor maps after glioma resection: a new parameter to integrate in the surgical strategy

PubMed Central

Duffau, H; Denvil, D; Capelle, L

2002-01-01

Objectives: To describe cortical reorganisation and the effects of glioma infiltration on local brain function in three patients who underwent two operations 12–24 months apart. Methods: Three patients who had no neurological deficit underwent two operations for low grade glioma, located in functionally important brain regions. During each operation, local brain function was characterised by electrical mapping and awake craniotomy. Results: Language or sensorimotor areas had been invaded by the tumour at the time of the first operation, leading to incomplete glioma removal in all cases. Because of a tumour recurrence, the patients were reoperated on between 12 and 24 months later. Functional reorganisation of the language, sensory, and motor maps was detected by electrical stimulation of the brain, and this allowed total glioma removal without neurological sequelae. Conclusions: These findings show that surgical resection of a glioma can lead to functional reorganisation in the peritumorous and infiltrated brain. It may be that this reorganisation is directly or indirectly caused by the surgical procedure. If this hypothesis is confirmed by other studies, the use of such brain plasticity potential could be used when planning surgical options in some patients with low grade glioma. Such a strategy could extend the limits of tumour resection in gliomas involving eloquent brain areas without causing permanent morbidity. PMID:11909913

Of a series of 122 children suffering from acute purulent meningitis at the Children's Hospital, Winnipeg, in the years 1952-56, 12 (9.8%) succumbed, all deaths occurring in those 12 months of age or less. Fortyone of the survivors were re-studied 2.5 to 7.5 years after their acute illness to assess the nature and incidence of sequelae, the relationship of sequelae to the severity of the acute illness, and the correlation between the various methods of identifying sequelae. Five children exhibited psychiatric evidence of organic brain damage; seven, neurological abnormality; 11, electroencephalographic abnormality. Three had defective intelligence and nine psychological test evidence of organic brain damage. Children with sequelae tended to have several abnormal test results, the total number with neuropsychiatric and/or psychological sequelae being 11 (26%). There was a positive correlation between the severity of the acute illness and the presence of neuropsychiatric sequelae; also between neuropsychiatric sequelae, defective intelligence and psychological evidence of brain damage. No correlation existed between the electroencephalographic abnormality and neuropsychiatric defect. PMID:13955939

Long-term effect of set potential on biocathodes in microbial fuel cells: electrochemical and phylogenetic characterization.

Xia, Xue; Sun, Yanmei; Liang, Peng; Huang, Xia

2012-09-01

The long-term effect of set potential on oxygen reducing biocathodes was investigated in terms of electrochemical and biological characteristics. Three biocathodes were poised at 200, 60 and -100 mV vs. saturated calomel electrode (SCE) for 110 days, including the first 17 days for startup. Electrochemical analyses showed that 60 mV was the optimum potential during long-term operation. The performance of all the biocathodes kept increasing after startup, suggesting a period longer than startup time needed to make potential regulation more effective. The inherent characteristics without oxygen transfer limitation were studied. Different from short-term regulation, the amounts of biomass were similar while the specific electrochemical activity was significantly influenced by potential. Moreover, potential showed a strong selection for cathode bacteria. Clones 98% similar with an uncultured Bacteroidetes bacterium clone CG84 accounted for 75% to 80% of the sequences on the biocathodes that showed higher electrochemical activity (60 and -100 mV).

Heterosynaptic changes accompany long-term but not short-term potentiation of the perforant path in the anaesthetized rat.

PubMed

Abraham, W C; Bliss, T V; Goddard, G V

1985-06-01

Brief high-frequency trains of electrical stimulation delivered to the perforant path result in long-term potentiation (l.t.p.) of field potentials recorded extracellularly from granule cells of the dentate gyrus. L.t.p. of the population spike is often disproportionately greater than l.t.p. of the population excitatory post-synaptic potential (e.p.s.p.). We have investigated the basis of this effect in rats anaesthetized with sodium pentobarbitone. A series of graded stimuli were given before and after tetanization of the perforant path. From data obtained in this way, we plotted stimulus-response curves, and the relation (E-S curve) between the slope of the population e.p.s.p. (E) and the amplitude of the population spike (S). Curves relating spike onset latency to the slope of the e.p.s.p. were also constructed. Tetanization of the combined medial and lateral components of the perforant path led to long-term changes in the relation between the e.p.s.p. and the population spike. For a given e.p.s.p., the corresponding population spike was of greater amplitude and earlier onset. This E-S potentiation was marked by a shift to the left of the E-S amplitude curve and a downward displacement of the E-S latency curve. Tetanization of the lateral component of the perforant path had two long-term effects on responses evoked by test stimuli to the untetanized medial component: (1) long-term depression of the medial e.p.s.p. and (2) long-term E-S potentiation. The net result of these two heterosynaptically induced effects was to leave unaltered information transfer across medial perforant path-granule cell synapses; for a given test volley the e.p.s.p. was smaller, but because of E-S potentiation the population spike remained relatively unaffected. Short-term potentiation, which has a time course of only a few minutes and is presumed to be mediated by presynaptic mechanisms, was not accompanied by E-S potentiation or by corresponding changes in spike latency. Possible mechanisms of long-term heterosynaptic depression of the e.p.s.p. and of homo- and heterosynaptic E-S potentiation, are discussed. We conclude that although these effects probably reflect a generalized post-synaptic change, this change is unlikely to be a prolonged reduction in the membrane potential of granule cells.

Novel clinical grading of delayed neurologic sequelae after carbon monoxide poisoning and factors associated with outcome.

Delayed neurologic sequelae (DNS) after carbon monoxide (CO) poisoning manifest as a relapse of neurologic deficits. However, the long-term outcome of DNS has not been fully clarified. Myelin basic protein (MBP) levels in the cerebrospinal fluid (CSF) have been reported to be elevated in DNS. However, the precise timing and clinical value of the CSF examination have not been fully evaluated. We aimed to clarify the long-term outcome and the factors predicting the outcome of DNS and to evaluate the utility of CSF-MBP for predicting the development and severity of DNS. This work was designed as a single-center, prospective, observational study. We graded DNS severity as Grade 1 (consistent independence), Grade 2 (temporary dependence), or Grade 3 (persistent dependence). We analyzed the percentage categorized in each grade and the parameters associated with outcome. Of 100 patients experiencing acute CO poisoning (median age: 46 years; 69% male), 20 (20%) developed DNS, including six Grade 1 (30%), ten Grade 2 (50%), and four Grade 3 (20%) cases. The Grade 3 patients [median: 77 years; interquartile range (IQR): 76-82] were older than the Grade 1 patients [42; 30-46] (P<0.01); the DNS onset of the Grade 1 patients [median interval after poisoning: 35 days; IQR: 32-56] occurred later than that of the Grade 3 patients [10; 9-13] P<0.001) and the Grade 2 patients [25; 23-27] (P<0.05). The CSF-MBP levels of the DNS patients were higher than those of the non-DNS patients (P<0.0001). The 1-month CSF-MBP levels of the Grade 3 patients were higher than those of the Grade 1 patients (P<0.05); the MBP index, defined as [(Age)×(1-month CSF-MBP)], was higher in the Grade 3 patients than in the Grade 1 patients (P<0.01). Severe DNS were associated with advanced age (>72.5 years), earlier onset (<18 days), higher 1-month CSF-MBP (>252 pg/ml), and higher MBP index (>20.9 year × ng/ml). Poor DNS outcomes were associated with advanced age and earlier onset. CSF-MBP can serve as a sensitive predictor of both the development and outcomes of DNS. Copyright © 2015 Elsevier Inc.

We questioned the assumption that rotator cuff tears must be repaired concurrently with instability syndromes, and aimed to allow a professional rugby league player to achieve career goals by NOT correcting all pathology at one surgery. Case Presentation A professional rugby league player presented with acute shoulder instability on a setting of a chronic full thickness rotator cuff tear. We performed an “in season” arthroscopic stabilization on an elite rugby league player, leaving a previously diagnosed large full thickness rotator cuff tear untreated. This allowed aggressive rehabilitation and return to contact competition at 12 weeks post-surgery. The player achieved a long held career goal of winning a premiership ring before undertaking rotator cuff repair at the end of the season. Latest follow up at seven years (still at elite level) demonstrated an asymptomatic shoulder. Conclusions The assumption that all pathology found at surgical exploration requires correction to play at elite level is not universally correct. We postulate that whilst rotator cuff deficiency has severe long-term sequelae, it is shoulder instability alone that prevents high level contact sports participation. Career goal management is an important part of managing elite level athletes. We have demonstrated that by careful management of the specific pathology preventing participation can allow elite athletes to achieve career goals without compromising long-term health.

The frequency of asymptomatic central line-associated thromboses is high and well recognized among children with cancer, while the long-term consequences are mainly unknown. In a cross-sectional study, we evaluated clinical and radiological venous outcome in children with previous long-standing intravascular catheters. The study enrolled 71 children previously treated for malignant or haematological diseases, 4-180 (median 37) mo after removal of their central lines. Inclusion criteria were a prior central line in a jugular vein for a minimum of 6 mo and no previous history of thrombosis. The children had clinical examination for post-thrombotic syndrome (PTS) and Doppler ultrasonography of the central neck veins. Twelve children had additional venous magnetic resonance imaging (MRI). But no kind of venography was performed in the remaining. We observed mild PTS with increased superficial collaterals in four children (6%), but no cases of more severe PTS. None complained of symptoms related to venous late effects. By ultrasonography, post-thrombotic venous alterations were detected in 17 children (24%), and five of these had complete occlusion of the veins. The sensitivity for pathologically increased collaterals to identify occlusive thrombosis was 0.6, while the specificity was 0.98. Occlusive venous thromboembolism was associated with the total number of central venous lines (CVLs; p=0.002), previous severe CVL-associated infections (p=0.001) and duration of central line in place (p=0.042). In spite of no prior history of thrombosis, children with previous long-term jugular lines frequently had local thrombotic sequelae, while clinical symptoms of PTS were rare.

Role of nitric oxide in long-term potentiation of the rat medial vestibular nuclei.

Grassi, S; Pettorossi, V E

2000-01-01

In rat brainstem slices, we investigated the role of nitric oxide in long-term potentiation induced in the ventral portion of the medial vestibular nuclei by high-frequency stimulation of the primary vestibular afferents. The nitric oxide scavenger [2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide ] and the nitric oxide synthase inhibitor N(G)-nitro-L-arginine methyl ester were administered before and after induction of potentiation. Both drugs completely prevented long-term potentiation, whereas they did not impede the potentiation build-up, or affect the already established potentiation. These results demonstrate that the induction, but not the maintenance of vestibular long-term potentiation, depends on the synthesis and release into the extracellular medium of nitric oxide. In addition, we analysed the effect of the nitric oxide donor sodium nitroprusside on vestibular responses. Sodium nitroprusside induced long-term potentiation, as evidenced through the field potential enhancement and unit peak latency decrease. This potentiation was impeded by D, L-2-amino-5-phosphonopentanoic acid, and was reduced under blockade of synaptosomal platelet-activating factor receptors by ginkgolide B and group I metabotropic glutamate receptors by (R,S)-1-aminoindan-1, 5-dicarboxylic acid. When reduced, potentiation fully developed following the washout of antagonist, demonstrating an involvement of platelet-activating factor and group I metabotropic glutamate receptors in its full development. Potentiation induced by sodium nitroprusside was also associated with a decrease in the paired-pulse facilitation ratio, which persisted under ginkgolide B, indicating that nitric oxide increases glutamate release independently of platelet-activating factor-mediated presynaptic events. We suggest that nitric oxide, released after the activation of N-methyl-D-aspartate receptors, acts as a retrograde messenger leading to an enhancement of glutamate release to a sufficient level for triggering potentiation. Once the synaptic efficacy has changed, it becomes a long-lasting phenomenon only through a subsequent action of platelet-activating factor.

Quality of life (QoL) and long-term prognosis are frequently, and often severely, impaired in craniopharyngioma (CP) patients. Knowledge of risk factors for long-term outcome is important for optimization of treatment. Overall survival (OS) and progression-free survival (PFS), body mass index (BMI), neuropsychological status (EORTCQLQ-C30, MFI-20), and psychosocial status were analyzed in 261 patients with childhood-onset CP diagnosed before 2000 and longitudinally observed in HIT-Endo. Twenty-year OS was lower (P = .006) in CP with hypothalamic involvement (HI) (n = 132; 0.84 ± 0.04) when compared with CP without HI (n = 82; 0.95 ± 0.04). OS was not related to degree of resection, sex, age at diagnosis, or year of diagnosis (before/after 1990). PFS (n = 168; 0.58 ± 0.05) was lower in younger patients (<5 y at diagnosis) (n = 30; 0.39 ± 0.10) compared with patients aged 5-10 years (n = 66; 0.52 ± 0.08) and older than 10 years (n = 72; 0.77 ± 0.06) at diagnosis. PFS was not associated with HI, degree of resection, or sex. HI led to severe weight gain during the first 8-12 years of follow-up (median BMI increase: +4.59SD) compared with no HI (median increase: +1.20SD) (P = .00). During >12 years of follow-up, patients with HI presented no further increase in BMI. QoL in CP patients with HI was impaired by obesity, physical fatigue, reduced motivation, dyspnea, diarrhea, and nonoptimal psychosocial development. OS and QoL are impaired by HI in long-term survivors of CP. HI is associated with severe obesity, which plateaus after 12 years. OS/PFS are not related to degree of resection, but gross-total resection should be avoided in cases of HI to prevent further hypothalamic damage, which exacerbates sequelae. © The Author(s) 2015.

Effects of metabotropic glutamate receptor block on the synaptic transmission and plasticity in the rat medial vestibular nuclei.

PubMed

Grassi, S; Malfagia, C; Pettorossi, V E

1998-11-01

In rat brainstem slices, we investigated the possible role of metabotropic glutamate receptors in modulating the synaptic transmission within the medial vestibular nuclei, under basal and plasticity inducing conditions. We analysed the effect of the metabotropic glutamate receptor antagonist (R,S)-alpha-methyl-4-carboxyphenylglycine on the amplitude of the field potentials and latency of unitary potentials evoked in the ventral portion of the medial vestibular nuclei by primary vestibular afferent stimulation, and on the induction and maintenance of long-term potentiation, after high-frequency stimulation. Two effects were observed, consisting of a slight increase of the field potentials and reduction of unit latency during the drug infusion, and a further long-lasting development of these modifications after the drug wash-out. The long-term effect depended on N-methyl-D-aspartate receptor activation, as D,L-2-amino-5-phosphonopentanoic acid prevented its development. We suggest that (R,S)-alpha-methyl-4carboxyphenylglycine enhances the vestibular responses and induces N-methyl-D-aspartate-dependent long-term potentiation by increasing glutamate release, through the block of presynaptic metabotropic glutamate receptors which actively inhibit it. The block of these receptors was indirectly supported by the fact that the agonist (1S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid reduced the vestibular responses and blocked the induction of long-term potentiation by high-frequency stimulation. The simultaneous block of metabotropic glutamate receptors facilitating synaptic plasticity, impedes the full expression of the long-term effect throughout the (R,S)-alpha-methyl-4-carboxyphenylglycine infusion. The involvement of such a facilitatory mechanism in the potentiation is supported by its reversible reduction following a second (R,S)-alpha-methyl-4-carboxyphenylglycine infusion. The drug also reduced the expression of potentiation induced by high-frequency stimulation. Conversely the electrical long-term potentiation was still induced, but it was occluded by the previous drug potentiation. We conclude that metabotropic glutamate receptors play a dual functional role in the medial vestibular nuclei, consisting in the inhibition of glutamate release under basal conditions, and the facilitation of N-methyl-D-aspartate-dependent plasticity phenomena.

Urological results after fetal myelomeningocele repair in pre-MOMS trial patients at the Children's Hospital of Philadelphia.

Myelomeningocele patients deal with multiple medical issues, including lower extremity neurological deficits, bowel and bladder incontinence and the sequelae of hydrocephalus secondary to a Chiari II malformation. In utero intervention holds the promise of reversing some of the sequelae and improving outcome. Between 1998 and 2003 (preceding the formal Management of Myelomeningocele Study, MOMS), an initial group of 58 patients underwent in utero repair of their myelomeningocele between 21 and 25 weeks' gestation. Long-term (5-year) follow-up has occurred in this cohort of patients. Previous reports have documented decreased incidence of ventriculoperitoneal shunting and neuromotor functioning, showing improved outcomes compared with historical controls. Overall, 4 fetal deaths occurred, while the majority of patients returned for follow-up for up to 5 years after closure. Phone follow-up has also been conducted for those who could not return. To date, 10 patients (18.5%) have successfully toilet-trained, while 2 patients have bowel continence and 1 has bladder continence but requires enemas; 2 patients who successfully toilet-trained developed spinal dermoid cysts requiring surgical resection. Historically, in utero repair of myelomeningocele patients yields a greater percentage of patients who have achieved continence compared with those undergoing postnatal repair. The MOMS trial will compare contemporary urological outcomes of those patients undergoing either prenatal or postnatal repair in a randomized fashion. The results of this trial showed a decreased need for ventriculoperitoneal shunting in those patients who underwent in utero repair as well as an improvement in lower extremity function. © 2014 S.

To review a single institution's 15-year experience with urethral foreign bodies, including evaluation, clinical findings, and treatment. In total, 27 patients comprising 35 episodes of inserted urethral foreign bodies were reviewed at Cook County Hospital between 2000 and 2015. Retrospective chart review was performed to describe the clinical presentation, rationale for insertion, management, recidivism, and sequelae. Median patient age was 26 (range 12-60). Twenty-six patients (97 %) were male, 1 was female (3%). Items inserted included pieces of plastic forks, spoons, metal screws and aluminum, pieces of cardboard or paper, staples, writing utensils such as pens and pencils, as well as coaxial cable and spray foam sealant. Reported reasons for insertion were self-stimulation, erectile enhancement, and attention seeking. Presenting symptoms included dysuria, gross hematuria, urinary retention, urinary tract infection, and penile discharge. The most common technique for removal was manual extraction with extrinsic pressure (n = 19, 54%). Other methods include endoscopic retrieval (n = 8, 23%), open cystotomy (n = 1, 3%), and voiding to expel the foreign body (n = 7, 20%). Postremoval complications included urinary tract infection (n = 7), sepsis (n = 4), urethral false passage (n = 5), laceration (n = 5), and stricture (n = 1). We present the largest single-institutional series of urethral foreign bodies to date. Urethral foreign body insertion is a relatively rare occurrence and, commonly, is a recurrent behavior. Urethral trauma related to foreign body insertion is associated with significant risk of infection and urethral injury with long-term sequelae. Copyright © 2016 Elsevier Inc. All rights reserved.

To evaluate the outcomes of eyelid reconstruction in patients who underwent full thickness skin grafts. A retrospective, noncomparative intervention study of patients who underwent periocular reconstruction with full thickness skin grafts between 2005 and 2011. One hundred consecutive Caucasian patients were included in the study, 54 women and 46 men. Mean follow up was 32 months. Indications for full thickness skin grafts were excision of eyelid tumors (98%) and cicatricial ectropion (2%). Site of lid defects were lower lid (60%), medial canthus (32%), upper lid (6%), and lateral canthus (2%). The skin graft donor sites were supraclavicular (44%), upper eyelid (24%), inner brachial (18%), and postauricular (14%).Early postoperative complications included lower eyelid graft contracture (1%) and partial failure (1%). Late sequelae included lower eyelid graft contracture (4%) and hypertrophic scarring (23%). Of the 23 patients with hypertrophic scar, 21 achieved good outcomes following massage with silicone gel and steroid ointment and 2 had persistent moderate lumpiness. No statistically significant association was found between graft hypertrophy and donor site or graft size. As high as 95% of all patients achieved good final eyelid position. Good color match was seen in 94% and graft hypopigmentation in 6%. An association between hypopigmentation and supraclavicular and inner brachial donor site was found to be statistically significant. Most patients (94%) achieved good eyelid position and color match. Majority (91%) of the early postoperative cicatricial sequelae can be reversed by massage, steroid ointment, and silicone gel application. Full thickness skin grafts have excellent graft survival rates and have minimal donor site morbidity.

Most enterovirus surveillance studies lack detailed clinical data, which limits their clinical usefulness. This study aimed to describe the clinical spectrum and outcome of severe enterovirus infections in children, and to determine whether there are associations between causative enterovirus genotypes and clinical phenotypes. Retrospective analysis of microbiological and clinical data from a tertiary children's hospital in the South of England over a 17-month period (2012-2013). In total, 30 patients were identified, comprising sepsis (n = 9), myocarditis (n = 8), meningitis (n = 8) and encephalitis (n = 5). Cases with sepsis or myocarditis were significantly younger than those with central nervous system disease (median age 21 and 15 days vs. 79 days; P = 0.0244 and P = 0.0310, respectively). There was considerable diversity in the causative genotypes in each of the clinical phenotypes, with some predominance of echoviruses in the meningitis group, and coxsackie B viruses in the myocarditis group. Thirteen cases required mechanical ventilation, 11 cases inotropic support, 3 cases dialysis and 3 cases extracorporal membrane oxygenation. The overall mortality was 10% (sepsis group, n = 1; myocarditis group, n = 2). Of the survivors, 5 (19%) had long-term sequelae (myocardial dysfunction, n = 2; neurological sequelae, n = 3). Patients with encephalitis had the longest hospital stay (median: 16 days), compared with 9, 6 and 3 days in patients with myocarditis, sepsis and meningitis, respectively (P = 0.005). Enterovirus infections, particularly enteroviral myocarditis and encephalitis, can cause significant morbidity and mortality. The results show that there are currently no strong associations between clinical phenotypes and particular causative enterovirus genotypes in the South of England.

Urinary tract infections (UTI) are among the most common bacterial infections in humans, affecting millions of people every year. UTI cause significant morbidity in women throughout their lifespan, in infant boys, in older men, in individuals with underlying urinary tract abnormalities, and in those that require long-term urethral catheterization, such as patients with spinal cord injuries or incapacitated individuals living in nursing homes. Serious sequelae include frequent recurrences, pyelonephritis with sepsis, renal damage in young children, pre-term birth, and complications of frequent antimicrobial use including high-level antibiotic resistance and Clostridium difficile colitis. Uropathogenic E. coli (UPEC) cause the vast majority of UTI, but less common pathogens such as Enterococcus faecalis and other enterococci frequently take advantage of an abnormal or catheterized urinary tract to cause opportunistic infections. While antibiotic therapy has historically been very successful in controlling UTI, the high rate of recurrence remains a major problem, and many individuals suffer from chronically recurring UTI, requiring long-term prophylactic antibiotic regimens to prevent recurrent UTI. Furthermore, the global emergence of multi-drug resistant UPEC in the past ten years spotlights the need for alternative therapeutic and preventative strategies to combat UTI, including anti-infective drug therapies and vaccines. In this chapter, we review recent advances in the field of UTI pathogenesis, with an emphasis on the identification of promising drug and vaccine targets. We then discuss the development of new UTI drugs and vaccines, highlighting the challenges these approaches face and the need for a greater understanding of urinary tract mucosal immunity.

Herpes Simplex Virus-1 (HSV-1) infections of the cornea range in severity from minor transient discomfort to the blinding disease Herpes Stromal Keratitis (HSK), yet most patients experience a single episode of epithelial keratitis followed by reestablishment of a clear cornea. We asked if a single transient episode of HSV-1 epithelial keratitis causes long-term changes in the corneal microenvironment that influence immune responses to subsequent corneal infection or trauma. We showed that C57BL/6 mouse corneas infected with HSV-1 KOS, which induces transient herpes epithelial keratitis without HSK sequelae, possessed a significant leukocytic infiltrate comprised primarily of CD4+ T cells and macrophages along with elevated chemokines and cytokines that persisted without loss of corneal clarity (subclinical inflammation). Chemokine and cytokine expression was CD4+T cell-dependent, in that their production was significantly reduced by systemic CD4+T cell depletion starting before infection, although short-term (3 day) local CD4+ T cell depletion after infection did not influence chemokine levels in cornea. Corneas with subclinical inflammation developed significantly greater trauma-induced inflammation when they were recipients of syngeneic corneal transplants, but also exhibited significantly increased resistance to infections by unrelated pathogens such as pseudorabies virus (PRV). The resistance to PRV was CD4+ T cell-dependent, since it was eliminated by local CD4+T cell-depletion from the cornea. We conclude that transient HSV-1 corneal infections cause long-term alterations of the corneal microenvironment that provide CD4-dependent innate resistance to subsequent infections by antigenically unrelated pathogens.

Delayed onset of neuropsychiatric symptoms after apparent recovery from acute carbon monoxide (CO) poisoning has been described as delayed neuropsychiatric sequelae (DNS). To date, there have been no studies on the utility of serum neuron-specific enolase (NSE), a marker of neuronal cell damage, as a predictive marker of DNS in acute CO poisoning. This retrospective observational study was performed on adult patients with acute CO poisoning consecutively treated over a 9-month period. Serum NSE was measured after emergency department arrival, and patients were divided into two groups. The DNS group comprised patients with delayed sequelae, while the non-DNS group included patients with none of these sequelae. A total of 98 patients with acute CO poisoning were enrolled in this study. DNS developed in eight patients. The median NSE value was significantly higher in the DNS group than in the non-DNS group. There was a statistical difference between the non-DNS group and the DNS group in terms of CO exposure time, Glasgow Coma Scale (GCS), loss of consciousness, creatinine kinase, and troponin I. GCS and NSE were the early predictors of development of DNS. The area under the curve according to the receiver operating characteristic curves of GCS, serum NSE, and GCS combined with serum NSE were 0.922, 0.836, and 0.969, respectively. In conclusion, initial GCS and NSE served as early predictors of development of DNS. Also, NSE might be a useful additional parameter that could improve the prediction accuracy of initial GCS.

Small molecules that activate signaling pathways used by neurotrophic factors could be useful for treating CNS disorders. Here we show that the flavonoid fisetin activates ERK and induces cAMP response element-binding protein (CREB) phosphorylation in rat hippocampal slices, facilitates long-term potentiation in rat hippocampal slices, and enhances object recognition in mice. Together, these data demonstrate that the natural product fisetin can facilitate long-term memory, and therefore it may be useful for treating patients with memory disorders. PMID:17050681

Preventive interventions are often designed and tested with the immediate program period in mind, and little thought that the intervention sample might be followed up for years or even decades beyond the initial trial. However, depending on the type of intervention and the nature of the outcomes, long-term follow-up may well be appropriate. The advantages of long-term follow-up of preventive interventions are discussed and include the capacity to examine program effects across multiple later life outcomes, the ability to examine the etiological processes involved in the development of the outcomes of interest, and the ability to provide more concrete estimates of the relative benefits and costs of an intervention. In addition, researchers have identified potential methodological risks of long-term follow-up such as inflation of type 1 error through post hoc selection of outcomes, selection bias, and problems stemming from attrition over time. The present paper presents a set of seven recommendations for the design or evaluation of studies for potential long-term follow-up organized under four areas: Intervention Logic Model, Developmental Theory and Measurement Issues; Design for Retention; Dealing with Missing Data; and Unique Considerations for Intervention Studies. These recommendations include conceptual considerations in the design of a study, pragmatic concerns in the design and implementation of the data collection for long-term follow-up, as well as criteria to be considered for the evaluation of an existing intervention for potential for long-term follow-up. Concrete examples from existing intervention studies that have been followed up over the long term are provided.

Global, regional, and national incidence, prevalence, and years lived with disability for 301 acute and chronic diseases and injuries in 188 countries, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

PubMed

2015-08-22

Up-to-date evidence about levels and trends in disease and injury incidence, prevalence, and years lived with disability (YLDs) is an essential input into global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013), we estimated these quantities for acute and chronic diseases and injuries for 188 countries between 1990 and 2013. Estimates were calculated for disease and injury incidence, prevalence, and YLDs using GBD 2010 methods with some important refinements. Results for incidence of acute disorders and prevalence of chronic disorders are new additions to the analysis. Key improvements include expansion to the cause and sequelae list, updated systematic reviews, use of detailed injury codes, improvements to the Bayesian meta-regression method (DisMod-MR), and use of severity splits for various causes. An index of data representativeness, showing data availability, was calculated for each cause and impairment during three periods globally and at the country level for 2013. In total, 35 620 distinct sources of data were used and documented to calculated estimates for 301 diseases and injuries and 2337 sequelae. The comorbidity simulation provides estimates for the number of sequelae, concurrently, by individuals by country, year, age, and sex. Disability weights were updated with the addition of new population-based survey data from four countries. Disease and injury were highly prevalent; only a small fraction of individuals had no sequelae. Comorbidity rose substantially with age and in absolute terms from 1990 to 2013. Incidence of acute sequelae were predominantly infectious diseases and short-term injuries, with over 2 billion cases of upper respiratory infections and diarrhoeal disease episodes in 2013, with the notable exception of tooth pain due to permanent caries with more than 200 million incident cases in 2013. Conversely, leading chronic sequelae were largely attributable to non-communicable diseases, with prevalence estimates for asymptomatic permanent caries and tension-type headache of 2·4 billion and 1·6 billion, respectively.

Global, regional, and national incidence, prevalence, and years lived with disability for 301 acute and chronic diseases and injuries in 188 countries, 1990–2013: a systematic analysis for the Global Burden of Disease Study 2013

PubMed Central

2015-01-01

Summary Background Up-to-date evidence about levels and trends in disease and injury incidence, prevalence, and years lived with disability (YLDs) is an essential input into global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013), we estimated these quantities for acute and chronic diseases and injuries for 188 countries between 1990 and 2013. Methods Estimates were calculated for disease and injury incidence, prevalence, and YLDs using GBD 2010 methods with some important refinements. Results for incidence of acute disorders and prevalence of chronic disorders are new additions to the analysis. Key improvements include expansion to the cause and sequelae list, updated systematic reviews, use of detailed injury codes, improvements to the Bayesian meta-regression method (DisMod-MR), and use of severity splits for various causes. An index of data representativeness, showing data availability, was calculated for each cause and impairment during three periods globally and at the country level for 2013. In total, 35 620 distinct sources of data were used and documented to calculated estimates for 301 diseases and injuries and 2337 sequelae. The comorbidity simulation provides estimates for the number of sequelae, concurrently, by individuals by country, year, age, and sex. Disability weights were updated with the addition of new population-based survey data from four countries. Findings Disease and injury were highly prevalent; only a small fraction of individuals had no sequelae. Comorbidity rose substantially with age and in absolute terms from 1990 to 2013. Incidence of acute sequelae were predominantly infectious diseases and short-term injuries, with over 2 billion cases of upper respiratory infections and diarrhoeal disease episodes in 2013, with the notable exception of tooth pain due to permanent caries with more than 200 million incident cases in 2013. Conversely, leading chronic sequelae were largely attributable to non-communicable diseases, with prevalence estimates for asymptomatic permanent caries and tension-type headache of 2·4 billion and 1·6 billion, respectively. The distribution of the number of sequelae in populations varied widely across regions, with an expected relation between age and disease prevalence. YLDs for both sexes increased from 537·6 million in 1990 to 764·8 million in 2013 due to population growth and ageing, whereas the age-standardised rate decreased little from 114·87 per 1000 people to 110·31 per 1000 people between 1990 and 2013.

Space Propulsion Synergy Group ETO technology assessments

Bray, James

The Space Propulsion Synergy Group (SPSG), which was chartered to support long-range strategic planning, has, using a broad industry/government team, evaluated and achieved consensus on the vehicles, propulsion systems, and propulsion technologies that have the best long-term potential for achieving desired system attributes. The breakthrough that enabled broad consensus was developing criteria that are measurable a priori. The SPSG invented a dual prioritization approach that balances long-term strategic thrusts with current programmatic constraints. This enables individual program managers to make decisions based on both individual project needs and long-term strategic needs. Results indicate that an SSTO using an integrated modular engine has the best long-term potential for a 20 Klb class vehicle, and that health monitoring and control technologies are among the highest dual priority liquid rocket technologies.

Anticipatory eye movements and long-term memory in early infancy.

PubMed

Wong-Kee-You, Audrey M B; Adler, Scott A

2016-11-01

Advances in our understanding of long-term memory in early infancy have been made possible by studies that have used the Rovee-Collier's mobile conjugate reinforcement paradigm and its variants. One function that has been attributed to long-term memory is the formation of expectations (Rovee-Collier & Hayne, 1987); consequently, a long-term memory representation should be established during expectation formation. To examine this prediction and potentially open the door on a new paradigm for exploring infants' long-term memory, using the Visual Expectation Paradigm (Haith, Hazan, & Goodman, 1988), 3-month-old infants were trained to form an expectation for predictable color and spatial information of picture events and emit anticipatory eye movements to those events. One day later, infants' anticipatory eye movements decreased in number relative to the end of training when the predictable colors were changed but not when the spatial location of the predictable color events was changed. These findings confirm that information encoded during expectation formation are stored in long-term memory, as hypothesized by Rovee-Collier and colleagues. Further, this research suggests that eye movements are potentially viable measures of long-term memory in infancy, providing confirmatory evidence for early mnemonic processes. © 2016 Wiley Periodicals, Inc.

Platelet-activating factor and group I metabotropic glutamate receptors interact for full development and maintenance of long-term potentiation in the rat medial vestibular nuclei.

In rat brainstem slices, we investigated the interaction between platelet-activating factor and group I metabotropic glutamate receptors in mediating long-term potentiation within the medial vestibular nuclei. We analysed the N1 field potential wave evoked in the ventral portion of the medial vestibular nuclei by primary vestibular afferent stimulation. The group I metabotropic glutamate receptor antagonist, (R,S)-1-aminoindan-1,5-dicarboxylic acid, prevented long-term potentiation induced by a platelet-activating factor analogue [1-O-hexadecyl-2-O-(methylcarbamyl)-sn-glycero-3-phosphocholine], as well as the full development of potentiation, induced by high-frequency stimulation under the blocking agent for synaptosomal platelet-activating factor receptors (ginkolide B), at drug washout. However, potentiation directly induced by the group I glutamate metabotropic receptor agonist, (R,S)-3,5-dihydroxyphenylglycine, was reduced by ginkolide B. These findings suggest that platelet-activating factor, whether exogenous or released following potentiation induction, exerts its effect through presynaptic group I metabotropic glutamate receptors, mediating the increase of glutamate release. In addition, we found that this mechanism, which led to full potentiation through presynaptic group I metabotropic glutamate receptor activation, was inactivated soon after application of potentiation-inducing stimulus. In fact, the long-lasting block of the platelet-activating factor and metabotropic glutamate receptors prevented the full potentiation development and the induced potentiation progressively declined to null. Moreover, ginkolide B, given when high-frequency-dependent potentiation was established, only reduced it within 5 min after potentiation induction. We conclude that to fully develop vestibular long-term potentiation requires presynaptic events. Platelet-activating factor, released after the activation of postsynaptic mechanisms which induce potentiation, is necessary for coupling postsynaptic and presynaptic phenomena, through the activation of group I metabotropic glutamate receptors, and its action lasts only for a short period. If this coupling does not occur, a full and long-lasting potentiation cannot develop.

Positive Emotions Speed Recovery from the Cardiovascular Sequelae of Negative Emotions.

Two studies tested the hypothesis that certain positive emotions speed recovery from the cardiovascular sequelae of negative emotions. In Study 1, 60 subjects (Ss) viewed an initial fear-eliciting film, and were randomly assigned to view a secondary film that elicited: (a) contentment; (b) amusement; (c) neutrality; or (d) sadness. Compared to Ss who viewed the neutral and sad secondary films, those who viewed the positive films exhibited more rapid returns to pre-film levels of cardiovascular activation. In Study 2, 72 Ss viewed a film known to elicit sadness. Fifty Ss spontaneously smiled at least once while viewing this film. Compared to Ss who did not smile, those who smiled exhibited more rapid returns to pre-film levels of cardiovascular activation. We discuss these findings in terms of emotion theory and possible health-promoting functions of positive emotions.

“The Biological Effects of Childhood Trauma”

I. Synopsis Trauma in childhood is a grave psychosocial, medical, and public policy problem that has serious consequences for its victims and for society. Chronic interpersonal violence in children is common worldwide. Developmental traumatology, the systemic investigation of the psychiatric and psychobiological effects of chronic overwhelming stress on the developing child, provides a framework and principles when empirically examining the neurobiological effects of pediatric trauma. Despite the widespread prevalence of childhood trauma, less is known about trauma's biological effects in children as compared to adults with child trauma histories; and even less is known about how these pediatric mechanisms underlie trauma's short-term and long-term medical and mental health consequences. This article focuses primarily on the peer-reviewed literature on the neurobiological sequelae of childhood trauma in children and adults with histories of childhood trauma. We also review relevant studies of animal models of stress to help us better understand the psychobiological effects of trauma during development. Next, we review the neurobiology of trauma, its clinical applications and the biomarkers that may provide important tools for clinicians and researchers, both as predictors of posttraumatic stress symptoms and as useful tools to monitor treatment response. Finally, we offer suggestions for future researchers. PMID:24656576

'Toy' laser macular burns in children: 12-month update.

There is increasing evidence that high-powered hand-held laser devices cause retinal injury. We present 12-month follow-up data for three patients that we previously reported with such retinal injuries. A retrospective case series of three children with maculopathy secondary to exposure to high-power hand-held laser devices. All children underwent clinical examination and spectral domain optical coherence tomography (SD-OCT) at presentation and follow-up. Fundus-controlled microperimetry was also undertaken 12-19 months after exposure. Three children sustained macular injury after exposure to a high-powered hand-held laser. Acutely, they presented with a 'vitelliform-like' maculopathy with reduced vision. Over the course of follow-up, the best corrected Snellen acuity in all three patients improved to 'normal' levels (range 6/6-6/9). Long-term deficits in foveal retinal sensitivity were identified in two patients using fundus-controlled microperimetry. SD-OCT imaging showed persistent disruption of the foveal outer photoreceptor layers in all three children. Although visual acuity improved over time, deficits in microperimetry and SD-OCT persisted. All three children had retinal pigment epithelium changes, requiring follow-up for longer-term sequelae of laser injuries such as expansion of retinal atrophy and development of choroidal neovascular membranes.

Toxoplasmosis in the fetus and newborn: an update on prevalence, diagnosis and treatment.

PubMed

Moncada, Pablo A; Montoya, Jose G

Toxoplasma gondii is an unicellular coccidian parasite with worldwide distribution. It is estimated that more than a third of the world's population has been infected with the parasite, but seroprevalence is unevenly distributed across countries and different socioeconomic strata. The majority of newborns with congenital toxoplasmosis do not have any clinical signs of the disease at birth; however, 30-70% of those with clinical abnormalities were not detected initially, and are found to have new retinal lesions consistent with toxoplasmicchorioretinitis later in life. Congenital toxoplasmosis can also cause fetal death, stillbirths or long-term disabling sequelae, particularly among untreated infants. The disease appears to be more frequent and severe at certain latitudes. Congenital toxoplasmosis can be prevented and treated during gestation. Less severe disease is commonly reported in countries where prenatal screening and treatment have been systematically implemented. By contrast, severe disease appears to be observed primarily in infants born to untreated mothers. For definition purposes, it is best to use the term toxoplasma or Toxoplasma gondii infection when referring to asymptomatic patients with primary or chronic infection, and toxoplasmosis when referring to patients with symptoms or signs.

Despite a considerable decrease in their incidence worldwide, burn injuries remain one of the commonest forms of trauma and account for a weighty proportion of trauma cases in health-care emergencies around the globe. Although the latest data reveal a substantial decline in burn-related mortality and hospital admissions in the US over the past three decades, severe thermal injuries continue to trigger devastating morbidity and significant mortality while their management remains a dynamic challenge for the entire medical and paramedical community. Concrete evidence continues to be established regarding burn-associated pathophysiologic responses, and their destructive sequelae and deleterious effects in survivors at cellular, systemic as well as socio-economic level. Better understanding of these responses have contributed to advances in therapeutic strategies, improved long-term outcomes and catalyzed the reintegration of victims back into society. This paper describes the current understanding of the pathophysiology of a burn injury and characterizes both local and systemic pathophysiologic responses in terms of metabolic, hemodynamics, cardiac, renal, hepatic, gastro-intestinal, immunologic, endocrine as well as male reproductive systems in an attempt to understand the corresponding treatment modalities for this unique patient population.

Disparities in long-term care: building equity into market-based reforms.

A growing body of evidence documents pervasive racial, ethnic, and class disparities in long-term care in the United States. At the same time, major quality improvement initiatives are being implemented that rely on market-based incentives, many of which may have the unintended consequence of exacerbating disparities. We review existing evidence on disparities in the use and quality of long-term care services, analyze current market-based policy initiatives in terms of their potential to ameliorate or exacerbate these disparities, and suggest policies and policy modifications that may help decrease disparities. We find that racial disparities in the use of formal long-term care have decreased over time. Disparities in quality of care are more consistently documented and appear to be related to racial and socioeconomic segregation of long-term care facilities as opposed to within-provider discrimination. Market-based incentives policies should explicitly incorporate the goal of mitigating the potential unintended consequence of increased disparities.
