    Full Text Available Abstract Background Many congenitally cytomegalovirus-infected (cCMV neonates are at risk for severe consequences, even if they are asymptomatic at birth. The assessment of the viral load in neonatal blood could help in identifying the babies at risk of sequelae. Methods In the present study, we elaborated the results obtained on blood samples collected in the first two weeks of life from 22 symptomatic and 48 asymptomatic newborns with cCMV diagnosed through urine testing. We evaluated the performances of two quantitative methods (pp65 antigenemia test and plasma Real-time PCR and the semi-quantitative results of dried blood sample (DBS test in the aim of identifying a valid method for measuring viral load. Results Plasma qPCR and DBS tests were positive in 100% of cases, antigenemia in 81%. Only the latter test gave quantitatively different results in symptomatic versus asymptomatic children. qPCR values of 103 copies/ml were found in 52% of newborn. "Strong" DBS test positivity cases had higher median values of both pp65 positive PBL and DNA copies/ml than cases with a "weak" positivity. Conclusions As expected antigenemia test was less sensitive than molecular tests and DBS test performed better on samples with higher rates of pp65 positive PBL and higher numbers of DNA copies/ml. The prognostic significance of the results of these tests will be evaluated on completion of the ongoing collection of follow-up data of these children.

    Full Text Available Cytomegalovirus (CMV is currently the most common agent of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Symptomatic congenital CMV infections usually result from maternal primary infection during early pregnancy. One half of symptomatic infants have cytomegalic inclusion disease (CID, which is characterized by involvement of multiple organs, in particular, the reticuloendothelial and central nervous system (CNS. Moreover, such involvement may or may not include ocular and auditory damage. Approximately 90% of infants with congenital infection are asymptomatic at birth. Preterm infants with perinatal CMV infection can have symptomatic diseases such as pneumonia, hepatitis, and thrombocytopenia. Microcephaly and abnormal neuroradiologic imaging are associated with a poor prognosis. Hearing loss may occur in both symptomatic and asymptomatic infants with congenital infection and may progress through childhood. Congenital infection is defined by the isolation of CMV from infants within the first 3 weeks of life. Ganciclovir therapy can be considered for infants with symptomatic congenital CMV infection involving the CNS. Pregnant women of seronegative state should be counseled on the importance of good hand washing and other control measures to prevent CMV infection. Heat treatment of infected breast milk at 72?#608;for 5 seconds can eliminate CMV completely.

    Congenital cytomegalovirus infection affects 0.7% of live births and is the leading cause of congenital neurological handicaps of infectious origin. However, systematic screening of this infection has not been implemented in pregnancy or at birth in any country. This apparent paradox has been justified by the unavailability of an efficient vaccine and by the scarcity of data available on the treatment of congenital CMV. However, in the last decade interesting new data on the management of this congenital infection has emerged including new results on both neonatal and postnatal treatments. This review provides an update on the potential benefits of antiviral treatment and on passive immunisation both in the neonatal and the antenatal periods. These suggest a benefit to a proactive approach for neonatal and prenatal congenital infections. PMID:27043943

    Full Text Available Abstract Background Human cytomegalovirus (CMV is one of the most commonly found agents of congenital infections. Primary maternal infection is associated with risk of symptomatic congenital diseases, and high morbidity is frequently associated with very low birth weight. Neonates with asymptomatic infection develop various sequelae during infancy. This is the first Argentine study performed in neonates with congenital and postnatal HCMV infection. The purpose of this study was to evaluate the performance of the polymerase chain reaction (PCR technique with different pairs of primers, to detect cytomegalovirus isolated in tissue cultures and directly in urine and dried blood spot (DBS specimens. Results were compared with IgM detection. Methods The study was performed between 1999 and 2001 on routine samples in the Laboratory. A total of 61 urine and 56 serum samples were selected from 61 newborns/infants, 33 patients whose samples were analyzed during the first two to three weeks of life were considered congenital infections; the remaining 28 patients whose samples were taken later than the third week were grouped as perinatal infections, although only in 4 the perinatal transmission of infection was determined unequivocally Cytomegalovirus diagnosis was made by isolating the virus from urine samples in human foreskin fibroblast cells. Three different primer pairs directed to IE, LA and gB genes were used for the HCMV PCR assay in viral isolates. Subsequently, PCR and nested PCR (nPCR assays with gB primers were performed directly in urine and in 11 samples of dried blood spot (DBS on Guthrie Card, these results were then compared with serology. Results The main clinical manifestations of the 33 patients with congenital infection were purpura, jaundice, hepatomegaly and anaemia. Three patients presented low birth weight as single symptom, 10, intracranial calcifications, and 2, kidney failure. In the 28 patients grouped as with perinatal

    Cytomegalovirus (CMV) infection is one of the most frequently encountered viral infections of the fetus and induces a wide range of histologic and clinical manifestations. Congenital abnormalities are typically restricted to the central nervous system despite evidence of CMV inclusions occurring in most epithelial cells. Although tissue injury and even glomerulonephritis have been observed in congenital CMV infections, renal multicystic dysplasia has not been reported. Herein, we describe a case of unilateral renal dysplasia in a 19-week fetus with concurrent CMV infection. We believe the present case to be the first description of a virus apparently inducing renal multicystic dysplasia. PMID:17638423

    Full Text Available Background. Congenital cytomegalovirus (CMV infection is a leading cause of disabilities in children, yet the general public appears to have little awareness of CMV. Methods. Women were surveyed about newborn infections at 7 different geographic locations. Results. Of the 643 women surveyed, 142 (22% had heard of congenital CMV. Awareness increased with increasing levels of education (P<.0001. Women who had worked as a healthcare professional had a higher prevalence of awareness of CMV than had other women (56% versus 16%, P <.0001. Women who were aware of CMV were most likely to have heard about it from a healthcare provider (54%, but most could not correctly identify modes of CMV transmission or prevention. Among common causes of birth defects and childhood illnesses, women's awareness of CMV ranked last. Conclusion. Despite its large public health burden, few women had heard of congenital CMV, and even fewer were aware of prevention strategies.

    The children (age 2 months to 8 years) with a congenital cytomegalovirus (CMV) infection were studied by magnetic resonance imaging (MRI) using a 2.35 Tesla magnet. CMV infection was confirmed by serological investigations and virus culture in the neonatal period. Nine children had severe mental retardation and cerebral palsy, 1 patient suffered from microcephaly, ataxia and deafness. The cranial MRI examination showed the following abnormalities (N): Dilated lateral ventricles (10) and subarachnoid space (8), oligo/pacgyria (8), delayed/pathological myelination (7), paraventricular cysts (6), intra-cerebral calcification (1). This lack of sensitivity for calcification is explainable by the basic principles of MRI. The paraventricular cystic lesions were adjacent ot the occipital horns of the lateral ventricles and separated only by a thin membrane. This finding might represent a 'new sign' for congenital CMV infection in MRI examinations, being characteristic but nevertheless nonspecific, like calcification in CT.

    Background Cytomegalovirus (CMV) is one of the most common causes of serious viral intrauterine infections. It is universally distributed among the human population with an average incidence of 0.15 to 2%. Indeed, at least half of the women in the reproductive age have evidence of prior CMV infection. Epidemiology and Pathogenicity However, it is not a usual practice to screen asymptomatic pregnant woman or neonates for CMV. Even if a mother developed a primary CMV infection during pregnancy, up to 90% of the newborns with congenital CMV will be asymptomatic at the time of birth. Only 5 to 7% of the infected babies will be acutely symptomatic, and the typical clinical presentation includes intrauterine growth restriction, microcephaly, various cutaneous manifestations (including petechiae and purpura), hematological abnormalities (particularly resistant thrombocytopenia), hepatosplenomegaly, chorioretinitis, hepatitis, etc. In contrast, acquired CMV infection is extremely unlikely to cause any serious sequelae for the infant. Cases  We present a case of congenital and acquired CMV infection in twins with a focus of dissimilarity in presentation, clinical course, and outcome. PMID:26929859

    Cytomegalovirus (CMV) is the most ubiquitous member of the herpes virus family and is the leading cause of congenital (vertical) infection in newborns (Fowler, Stagno, & Pass, 2003; Llorente, Steigmeyer, Cooper, Rivers, & Gazley, 2011; Noyola et al., 2000; Steigmeyer & Llorente, 2010). CMV is related to the group of viruses capable of causing more pernicious infectious diseases, such as chicken pox (Santos de Barona, 1998). Although the virus generally remains dormant, individuals whose symptoms are clinically apparent often are dramatically affected. Common symptomatic characteristics of the virus include microcephaly, jaundice, liver-spleen infections, pneumonia, cardiac anomalies, chorioretinitis, vision loss, sensory-neural hearing loss, mental retardation, and mononucleosis (Demmler, 1991; Kashden, Frison, Fowler, Pass, & Boll, 1998; Noyola et al., 2000; Pass, 2005; Santos de Barona). The prognosis of individuals with CMV is highly variable, and the prognosis of individuals with congenital CMV can usually be determined based on the extent of infection at birth. The purpose of this investigation is to present longitudinal results of neuropsychological evaluation of two dizygotic twin sets (one twin of each set is asymptomatic CMV-positive and the other is uninfected) who were reared in the same environment. In addition, the present findings are discussed within the context of emerging murine and other animal analogues of CMV as well as within the extant CMV literature. PMID:23428280

    Human cytomegalovirus (CMV) is under-recognised, despite being the leading infectious cause of congenital malformation, affecting ~0.3% of Australian live births. Approximately 11% of infants born with congenital CMV infection are symptomatic, resulting in clinical manifestations, including jaundice, hepatosplenomegaly, petechiae, microcephaly, intrauterine growth restriction and death. Congenital CMV infection may cause severe long-term sequelae, including progressive sensorineural hearing loss and developmental delay in 40-58% of symptomatic neonates, and ~14% of initially asymptomatic infected neonates. Up to 50% of maternal CMV infections have nonspecific clinical manifestations, and most remain undetected unless specific serological testing is undertaken. The combination of serology tests for CMV-specific IgM, IgG and IgG avidity provide improved distinction between primary and secondary maternal infections. In pregnancies with confirmed primary maternal CMV infection, amniocentesis with CMV-PCR performed on amniotic fluid, undertaken after 21-22 weeks gestation, may determine whether maternofetal virus transmission has occurred. Ultrasound and, to a lesser extent, magnetic resonance imaging are valuable tools to assess fetal structural and growth abnormalities, although the absence of fetal abnormalities does not exclude fetal damage. Diagnosis of congenital CMV infection at birth or in the first 3 weeks of an infant's life is crucial, as this should prompt interventions for prevention of delayed-onset hearing loss and neurodevelopmental delay in affected infants. Prevention strategies should also target mothers because increased awareness and hygiene measures may reduce maternal infection. Recognition of the importance of CMV in pregnancy and in neonates is increasingly needed, particularly as therapeutic and preventive interventions expand for this serious problem. PMID:26391432

    Full Text Available Objectives: This study aimed to compare polymerase chain reaction (PCR and IgM detection using enzyme linked immune-sorbent assay (ELISA in diagnosis of congenital cytomegalovirus (CMV infection.   Methods: This study was conducted from May 2009 to December 2010. Urine and blood samples were collected from 94 neonates with suspected congenital CMV infection. Serum and part of urine samples were stored at -20°C freezer, until the serologic and PCR tests were achieved. A 94 fresh urine samples were processed for cell culture. Nineteen (20.2% out of 94 urine samples were proven positive for CMV infection by viral culture. For comparing PCR and IgM ELISA we used tissue culture technique as a reference, the 19 positive samples on culture (CMV group and 20 negative samples (control group were included in the comparison. Some characteristics of CMV and control groups were compared including sex, age, birth weight, gestational age < 37 and small for gestational age. Clinical and laboratory abnormalities were also compared in both groups.   Results: This study showed that the sensitivity and specificity of PCR in relation to viral culture were 100% and 100% respectively, there was excellent agreement between both tests (Kappa coefficient was 1 and P=0.000. On the other hand, the sensitivity of IgM CMV ELISA in relation to viral culture was 63.2% and the specificity was 85%. There was good agreement between both tests (Kappa coefficient was 0.48 and P=0.002. By comparing CMV and control groups, there were high statistically significant differences between both groups as regard the birth weight, gestational age < 37 and small for gestational age items (P= 0.00, 0.03 and 0.01 respectively. There were statistically insignificant differences as regarding the clinical and laboratory abnormalities detected for neonates of both groups. In this study jaundice (63% and hepato-splenomegaly (42% were the most common clinical signs in both groups.   Conclusion

    Full Text Available Abstract Background Each year in the United States, an estimated 40,000 children are born with congenital cytomegalovirus (CMV infection, causing an estimated 400 deaths and leaving approximately 8000 children with permanent disabilities such as hearing or vision loss, or mental retardation. More children are affected by serious CMV-related disabilities than by several better-known childhood maladies, including Down syndrome, fetal alcohol syndrome, and spina bifida. Discussion Congenital CMV is a prime target for prevention not only because of its substantial disease burden but also because the biology and epidemiology of CMV suggest that there are ways to reduce viral transmission. Because exposure to the saliva or urine of young children is a major cause of CMV infection among pregnant women, it is likely that good personal hygiene, especially hand-washing, can reduce the risk of CMV acquisition. Experts agree that such measures are likely to be efficacious (i.e., they will work if consistently followed and the American College of Obstetricians and Gynecologists recommends that physicians counsel pregnant women about preventing CMV acquisition through careful attention to hygiene. However, because of concerns about effectiveness (i.e., Will women consistently follow hygienic practices as the result of interventions?, the medical and public health communities appear reluctant to embrace primary CMV prevention via improved hygienic practices, and educational interventions are rare. Current data on the effectiveness of such measures in preventing CMV infection are promising, but limited. There is strong evidence, however, that educational interventions can prevent other infectious diseases with similar transmission modes, suggesting that effective interventions can also be found for CMV. Until a CMV vaccine becomes available, effective educational interventions are needed to inform women about congenital CMV prevention. Summary Perhaps no single

    Congenital cytomegalovirus (CMV) infection has been called "the elephant in our living room" because it is a major public health problem that for decades has been unrecognized and unaddressed. Congenital CMV infection is a common cause of sensorineural hearing loss, vision loss, neurodevelopment disabilities, liver disease, and growth failure. Diagnostic tests are now widely available to identify newborns with congenital CMV infection, congenitally infected newborns now can be easily assessed for evidence of organ involvement, and there are now antiviral treatments and other interventions available to improve the outcome in children with congenital CMV disease. A licensed vaccine to prevent CMV infection is not yet available; however, a "CMV knowledge vaccine," composed of "an ounce of CMV awareness and three simple precautions" and that is endorsed by the Centers for Disease Control and Prevention is available for pregnant women who wish to reduce their contact with potentially CMV-infected secretions and therefore reduce their risk of acquiring CMV during pregnancy. Medical experts in the field of congenital CMV have been called upon for a consensus statement for diagnosis and treatment, and nonprofit organizations of families affected by congenital CMV from around the world have formed a collaborative coalition to facilitate the spread of CMV knowledge and awareness.

    Human Cytomegalovirus (HCMV) infection still represents the most common potentially serious viral complication in humans and is a major cause of congenital anomalies in infants. This study is aimed to detect HCMV in infants with congenital anomalies. Study subjects consisted of infants born with neural tube defect, hydrocephalus and microcephaly. Fifty serum specimens (20 males, 30 females) were collected from different hospitals in Khartoum State. The sera were investigated for cytomegalovirus specific immunoglobin M (IgM) antibodies using enzyme-linked immunosorbent assay (ELISA), and for Cytomegalovirus DNA using polymerase chain reaction (PCR). Out of the 50 sera tested, one patient’s (2%) sample showed HCMV IgM, but with no detectable DNA, other 4(8.2 %) sera were positive for HCMV DNA but with no detectable IgM. Various diagnostic techniques should be considered to evaluate HCMV disease and routine screening for HCMV should be introduced for pregnant women in this setting. It is vital to initiate further research work with many samples from different area to assess prevalence and characterize HCMV and evaluate its maternal health implications. PMID:26862356

    Congenital cytomegalovirus (CMV) is the most common congenital infection in the United States, causing permanent disabilities in more than 5,500 children born each year. In the absence of a vaccine, a promising means of prevention is through a behavioral intervention that educates women about CMV and promotes adherence to hygiene guidelines during pregnancy. Although effective behavioral interventions have been identified for other infectious diseases with similar transmission modes, current research has not yet identified an effective intervention for CMV. One way to gather evidence and identify key elements of a successful CMV intervention is through a social marketing approach. This article describes a five-step process for applying social marketing principles to the research and development, implementation, and evaluation of a CMV behavioral intervention. PMID:19515860

    Although the neuroradiological findings of congenital cytomegalovirus (CMV) infection are well known, little has been reported concerning the imaging findings of paraventricular cysts occurring in patients with cytomegalovirus infection involving the brain. The purpose of this study is to describe the features of paraventricular cysts observed at MRI and ultrasonography. MR and ultrasonographic studies of ten patients with congenital cytomegalovirus infections involving the brain were retrospectively reviewed. Diagnosis was confirmed by positive culture of the virus in urine (n=4), the presence of CMV Ig G antibody (n=4), or positive CMV Ig M antibody (n=2), and on the basis of characteristic MR imaging findings. Initial MRI in all patients and initial ultrasonography in four of five with paraventricular cysts were performed. Three patients underwent follow-up MRI and ultrasonography for the evaluation of cystic change, and the size, location, bilaterality and morphology of the cysts were evaluated. Bilateral paraventricular cysts averaging 15 (range. 10-23) mm in size were found in five of the ten patients (50%). They were adjacent to the foramen of Monro in three cases, the occipital horn in one, an dthe temporal horn in one. MR imaging showed that the fluid content of all cysts was of similar signal intensity to cerebrospinal fluid (T1-WI, hypointense; T2-WI, hyperintense). The ultrasonographic findings varied: there was one pure cyst and one with a thick wall and septations, and two contained complex fluid. In three patients, follow up MRI and ultrasonography showed that the cysts disappeared after 4-23 months. Although paraventricular cysts may appear at MRI to be purely cystic, ultrasonography may indicate that their contents are more complex, or that septations are present.

Diagnosis was confirmed by positive culture of the virus in urine (n=4), the presence of CMV Ig G antibody (n=4), or positive CMV Ig M antibody (n=2), and on the basis of characteristic MR imaging findings. Initial MRI in all patients and initial ultrasonography in four of five with paraventricular cysts were performed. Three patients underwent follow-up MRI and ultrasonography for the evaluation of cystic change, and the size, location, bilaterality and morphology of the cysts were evaluated. Bilateral paraventricular cysts averaging 15 (range. 10-23) mm in size were found in five of the ten patients (50%). They were adjacent to the foramen of Monro in three cases, the occipital horn in one, an dthe temporal horn in one. MR imaging showed that the fluid content of all cysts was of similar signal intensity to cerebrospinal fluid (T1-WI, hypointense; T2-WI, hyperintense). The ultrasonographic findings varied: there was one pure cyst and one with a thick wall and septations, and two contained complex fluid. In three patients, follow up MRI and ultrasonography showed that the cysts disappeared after 4-23 months. Although paraventricular cysts may appear at MRI to be purely cystic, ultrasonography may indicate that their contents are more complex, or that septations are present

    We present the case of a 6-year-old boy who received a cochlear implant for profound sensorineural hearing loss after being born with cytomegalovirus (CMV) infection. Even after 6 years, CMV DNA was still found in the perilymph of the cochlea. Our case shows that CMV DNA can be present in the cochlea years after congenital CMV infection, and it can explain why progressive and/or late-onset hearing loss occurs in these children.

    Congenital infection by human cytomegalovirus (HCMV) is a leading cause of permanent sequelae of the central nervous system, including sensorineural deafness, cerebral palsies or devastating neurodevelopmental abnormalities (0.1% of all births). To gain insight on the impact of HCMV on neuronal development, we used both neural stem cells from human embryonic stem cells (NSC) and brain sections from infected fetuses and investigated the outcomes of infection on Peroxisome Proliferator-Activated Receptor gamma (PPARγ), a transcription factor critical in the developing brain. We observed that HCMV infection dramatically impaired the rate of neuronogenesis and strongly increased PPARγ levels and activity. Consistent with these findings, levels of 9-hydroxyoctadecadienoic acid (9-HODE), a known PPARγ agonist, were significantly increased in infected NSCs. Likewise, exposure of uninfected NSCs to 9-HODE recapitulated the effect of infection on PPARγ activity. It also increased the rate of cells expressing the IE antigen in HCMV-infected NSCs. Further, we demonstrated that (1) pharmacological activation of ectopically expressed PPARγ was sufficient to induce impaired neuronogenesis of uninfected NSCs, (2) treatment of uninfected NSCs with 9-HODE impaired NSC differentiation and (3) treatment of HCMV-infected NSCs with the PPARγ inhibitor T0070907 restored a normal rate of differentiation. The role of PPARγ in the disease phenotype was strongly supported by the immunodetection of nuclear PPARγ in brain germinative zones of congenitally infected fetuses (N = 20), but not in control samples. Altogether, our findings reveal a key role for PPARγ in neurogenesis and in the pathophysiology of HCMV congenital infection. They also pave the way to the identification of PPARγ gene targets in the infected brain. PMID:27078877

  11. Fatal congenital cytomegalovirus infection following recurrent maternal infection after a 7-year interval

    International Nuclear Information System (INIS)

    It is generally accepted that the risk for fetal infection is greatest with maternal primary cytomegalovirus (CMV) infection and much less likely with recurrent infection. Here, we report a fatal case of congenital CMV infection following recurrent maternal infectious after a 7-year interval. A 3-months-old female baby presented with fever, jaundice, vomiting and stopping breast-feeding. Physical examination revealed mild respiratory distress, hepatosplenomegaly, microcephaly and growth retardation. Laboratory examination included bilirubin concentrations (total 7.17 mg/dl; conjugated 6.67 mg/dl), aspartate transaminase (141 IU), and alanine transminase (141 IU), and alanine transminase (499 IU). Enzyme linked immunosorbent assay test results revealed (+) CMV IgM and (+) CMV IgG. She died on the 10 th day of admission with the diagnosis of CMV hepatitis, pneumonia and multi-organ failure. Nuclear and cytoplasmic inclusions demonstrated in the lung, liver and brain on postmortem biopsy. This case highlights that the outcome of babies born to mothers with recurrent maternal CMV infection may be more severe and fatal than previously thought. (author)

  12. A Homolog Pentameric Complex Dictates Viral Epithelial Tropism, Pathogenicity and Congenital Infection Rate in Guinea Pig Cytomegalovirus.

    In human cytomegalovirus (HCMV), tropism to epithelial and endothelial cells is dependent upon a pentameric complex (PC). Given the structure of the placenta, the PC is potentially an important neutralizing antibody target antigen against congenital infection. The guinea pig is the only small animal model for congenital CMV. Guinea pig cytomegalovirus (GPCMV) potentially encodes a UL128-131 HCMV PC homolog locus (GP128-GP133). In transient expression studies, GPCMV gH and gL glycoproteins interacted with UL128, UL130 and UL131 homolog proteins (designated GP129 and GP131 and GP133 respectively) to form PC or subcomplexes which were determined by immunoprecipitation reactions directed to gH or gL. A natural GP129 C-terminal deletion mutant (aa 107-179) and a chimeric HCMV UL128 C-terminal domain swap GP129 mutant failed to form PC with other components. GPCMV infection of a newly established guinea pig epithelial cell line required a complete PC and a GP129 mutant virus lacked epithelial tropism and was attenuated in the guinea pig for pathogenicity and had a low congenital transmission rate. Individual knockout of GP131 or 133 genes resulted in loss of viral epithelial tropism. A GP128 mutant virus retained epithelial tropism and GP128 was determined not to be a PC component. A series of GPCMV mutants demonstrated that gO was not strictly essential for epithelial infection whereas gB and the PC were essential. Ectopic expression of a GP129 cDNA in a GP129 mutant virus restored epithelial tropism, pathogenicity and congenital infection. Overall, GPCMV forms a PC similar to HCMV which enables evaluation of PC based vaccine strategies in the guinea pig model. PMID:27387220

    Full Text Available INTRODUCTION: Although urine is considered the gold-standard material for the detection of congenital cytomegalovirus (CMV infection, it can be difficult to obtain in newborns. The aim of this study was to compare the efficiency of detection of congenital CMV infection in saliva and urine samples. METHODS: One thousand newborns were included in the study. Congenital cytomegalovirus deoxyribonucleic acid (DNA was detected by polymerase chain reaction (PCR. RESULTS: Saliva samples were obtained from all the newborns, whereas urine collection was successful in only 333 cases. There was no statistically significant difference between the use of saliva alone or saliva and urine collected simultaneously for the detection of CMV infection. CONCLUSIONS: Saliva samples can be used in large-scale neonatal screening for CMV infection.

    Full Text Available Abstract Background The objective of this study was to compare intravaginal (ivg and subcutaneous (sc administration of the guinea pig cytomegalovirus (GPCMV in pregnant and non-pregnant guinea pigs. These studies tested the hypotheses that ivg infection would elicit immune responses, produce maternal viremia, and lead to vertical transmission, with an efficiency similar to the traditionally employed sc route. Results Four groups of age- and size-matched guinea pigs were studied. Two groups were pregnant, and two groups were not pregnant. Animals received 5x105 plaque-forming units (PFU of a GPCMV reconstituted from an infectious bacterial artificial chromosome (BAC construct containing the full-length GPCMV genome. Seroconversion was compared by IgG ELISA, and viremia (DNAemia was monitored by PCR. In both pregnant and non-pregnant animals, sc inoculation resulted in significantly higher serum ELISA titers than ivg inoculation at 8 and 12 weeks post-infection. Patterns of viremia (DNAemia were similar in animals inoculated by either sc or ivg route. However, in pregnant guinea pigs, animals inoculated by both routes experienced an earlier onset of DNAemia than did non-pregnant animals. Neither the percentage of dead pups nor the percentage of GPCMV positive placentas differed by inoculation route. Conclusions In the guinea pig model of congenital CMV infection, the ivg route is as efficient at causing congenital infection as the conventional but non-physiologic sc route. This finding could facilitate future experimental evaluation of vaccines and antiviral interventions in this highly relevant animal model.

    BACKGROUND: Cytomegalovirus (CMV) is a herpesvirus and the most common cause of congenital infection in developed countries. Congenital CMV infection can have devastating consequences to the fetus. The high incidence and the serious morbidity associated with congenital CMV infection emphasise the need for effective interventions to prevent the antenatal transmission of CMV infection. OBJECTIVES: The aim of this review was to assess the benefits and harms of interventions used during pregnancy to prevent mother to fetus transmission of CMV infection. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group\\'s Trials Register (31 December 2010). SELECTION CRITERIA: All randomised controlled trials (RCTs) and quasi RCTs investigating antenatal interventions for preventing the transmission of CMV from the mother to fetus during pregnancy and adverse outcomes in the congenitally infected infant. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion. MAIN RESULTS: We identified six studies from the search. None of these studies met the pre-defined criteria for inclusion in this review. AUTHORS\\' CONCLUSIONS: To date, no RCTs are available that examine antenatal interventions for preventing the transmission of CMV from the infected mother to fetus during pregnancy and adverse outcomes in the congenitally infected infant. Further research is needed to assess the efficacy of interventions aimed at preventing the transmission of CMV from the mother to fetus during pregnancy including a long-term follow-up of exposed infants and a cost effective analysis.

    Two protocols for the extraction of cytomegalovirus (CMV) DNA and two methods for the amplification of CMV DNA in dried blood spots were evaluated for the retrospective diagnosis of congenital CMV infection. During the period from 1996 to 2006, a urine screening program detected 76 congenitally infected neonates. Stored Guthrie cards with blood from 55 cases and 12 controls were tested. Two spots of dried blood were cut from each card and evaluated in two centers. CMV DNA was extracted from a whole single spot. Center 1 used phenol-chloroform extraction and ethanol precipitation followed by a conventional PCR. Center 2 used the NucliSens easyMAG automated DNA/RNA extraction platform (bioMérieux) followed by a real-time PCR. For evaluation of the extraction method, DNA extracted from each blood spot was evaluated by the amplification method used by the collaborating center. The sensitivities were 66% for center 1 and 73% for center 2. None of the controls were positive. A sensitivity as high as 82% could be obtained by combining the most sensitive extraction method (the phenol-chloroform procedure) with the most sensitive PCR method (real-time PCR). The detection rate was not influenced by the duration of storage of the spots. The sensitivity was higher with blood from congenitally infected cases due to a primary maternal CMV infection, regardless of the protocol used. However, the difference reached significance only for the least-sensitive protocol (P = 0.036). PMID:18199787

    Today's registration of newborns with congenital cytomegalovirus (cCMV) infection is still performed on paper-based forms in Flanders, Belgium. This process has a large administrative impact. It is important that all screening tests are registered to have a complete idea of the impact of cCMV. Although these registrations are usable in computerised data analysis, these data are not available in a format to perform electronic processing. An online Neonatal Registry (NEOREG) System was designed and developed to access, follow and analyse the data of newborns remotely. It allows remote access and monitoring by the physician. The Java Enterprise layered application provides patients' diagnostic registration and treatment follow-up through a web interface and uses document forms in Portable Document Format (PDF), which incorporate all the elements from the existing forms. Forms are automatically processed to structured EHRs. Modules are included to perform statistical analysis. The design was driven by extendibility, security and usability requirements. The website load time, throughput and execution time of data analysis were evaluated in detail. The NEOREG system is able to replace the existing paper-based CMV records. PMID:23323747

  5. Contribution of dysferlin deficiency to skeletal muscle pathology in asymptomatic and severe dystroglycanopathy models: generation of a new model for Fukuyama congenital muscular dystrophy.

    Directory of Open Access Journals (Sweden)

    Full Text Available Defects in dystroglycan glycosylation are associated with a group of muscular dystrophies, termed dystroglycanopathies, that include Fukuyama congenital muscular dystrophy (FCMD. It is widely believed that abnormal glycosylation of dystroglycan leads to disease-causing membrane fragility. We previously generated knock-in mice carrying a founder retrotransposal insertion in fukutin, the gene responsible for FCMD, but these mice did not develop muscular dystrophy, which hindered exploring therapeutic strategies. We hypothesized that dysferlin functions may contribute to muscle cell viability in the knock-in mice; however, pathological interactions between glycosylation abnormalities and dysferlin defects remain unexplored. To investigate contributions of dysferlin deficiency to the pathology of dystroglycanopathy, we have crossed dysferlin-deficient dysferlin(sjl/sjl mice to the fukutin-knock-in fukutin(Hp/- and Large-deficient Largemyd/myd mice, which are phenotypically distinct models of dystroglycanopathy. The fukutin(Hp/- mice do not show a dystrophic phenotype; however, (dysferlin(sjl/sjl: fukutin(Hp/- mice showed a deteriorated phenotype compared with (dysferlinsjl/sjl: fukutin(Hp/+ mice. These data indicate that the absence of functional dysferlin in the asymptomatic fukutin(Hp/- mice triggers disease manifestation and aggravates the dystrophic phenotype. A series of pathological analyses using double mutant mice for Large and dysferlin indicate that the protective effects of dysferlin appear diminished when the dystrophic pathology is severe and also may depend on the amount of dysferlin proteins. Together, our results show that dysferlin exerts protective effects on the fukutin(Hp/- FCMD mouse model, and the (dysferlin(sjl/sjl: fukutin(Hp/- mice will be useful as a novel model for a recently proposed antisense oligonucleotide therapy for FCMD.

    Full Text Available Abstract Background Human T-cell leukemia virus type 1 (HTLV-1 causes adult T-cell leukemia (ATL and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP in a small percentage of infected individuals. ATL is often associated with general immune suppression and an impaired HTLV-1-specific T-cell response, an important host defense system. We previously found that a small fraction of asymptomatic HTLV-1-carriers (AC already showed impaired T-cell responses against the major target antigen, Tax. However, it is unclear whether the impaired HTLV-1 Tax-specific T-cell response in these individuals is an HTLV-1-specific phenomenon, or merely reflects general immune suppression. In this study, in order to characterize the impaired HTLV-1-specific T-cell response, we investigated the function of Tax-specific CD8+ T-cells in various clinical status of HTLV-1 infection. Results By using tetramers consisting of HLA-A*0201, -A*2402, or -A*1101, and corresponding Tax epitope peptides, we detected Tax-specific CD8+ T-cells in the peripheral blood from 87.0% of ACs (n = 20/23 and 100% of HAM/TSP patients (n = 18/18 tested. We also detected Tax-specific CD8+ T-cells in 38.1% of chronic type ATL (cATL patients (n = 8/21, although its frequencies in peripheral blood CD8+ T cells were significantly lower than those of ACs or HAM/TSP patients. Tax-specific CD8+ T-cells detected in HAM/TSP patients proliferated well in culture and produced IFN-γ when stimulated with Tax peptides. However, such functions were severely impaired in the Tax-specific CD8+ T-cells detected in cATL patients. In ACs, the responses of Tax-specific CD8+ T-cells were retained in most cases. However, we found one AC sample whose Tax-specific CD8+ T-cells hardly produced IFN-γ, and failed to proliferate and express activation (CD69 and degranulation (CD107a markers in response to Tax peptide. Importantly, the same AC sample contained cytomegalovirus (CMV pp65-specific CD8+ T

    Cytomegalovirus (CMV) infection in inmunocompetent hosts generally is asymptomatic or may present as a mononucleosis syndrome but rarely can lead to severe organ complications. We report a case of simultaneous hepatic and pericardic CMV infection in a 36-year old immunocompetent man. He was admitted to coronary unit with fever, chest pain radiated to shoulders,changes on electrocardiogram with diffuse ST elevation and modest laboratory elevations in the MB fraction of creatine kinase (CK-MB) of 33.77 μg/L (0.1-6.73), serum cardiac troponin T of 0.904 ng/mL (0-0.4), creatine kinase of 454 U/L (20-195) and myoglobin of 480.4 μg/L (28-72). Routine laboratory test detected an elevation of aminotransferase level: alanine aminotransferase 1445 U/L, aspartate aminotransferase 601 U/L. We ruled out other causes of hepatitis with normal results except IgM CMV. The patient was diagnosed with myopericarditis and hepatitis caused by cytomegalovirus and started symptomatic treatment with salicylic acid. In few days the laboratory findings became normal and the patient was discharged.

    Cytomegalovirus (CMV) is the most common cause of congenital infection, and is a major cause of sensorineural hearing loss and neurological disabilities. Evaluating the risk for a CMV infected fetus to develop severe clinical symptoms after birth is crucial to provide appropriate guidance to pregnant women who might have to consider termination of pregnancy or experimental prenatal medical therapies. However, establishing the prognosis before birth remains a challenge. This evaluation is currently based upon fetal imaging and fetal biological parameters, but the positive and negative predictive values of these parameters are not optimal, leaving room for the development of new prognostic factors. Here, we compared the amniotic fluid peptidome between asymptomatic fetuses who were born as asymptomatic neonates and symptomatic fetuses who were either terminated in view of severe cerebral lesions or born as severely symptomatic neonates. This comparison allowed us to identify a 34-peptide classifier in a discovery cohort of 13 symptomatic and 13 asymptomatic neonates. This classifier further yielded 89% sensitivity, 75% specificity and an area under the curve of 0.90 to segregate 9 severely symptomatic from 12 asymptomatic neonates in a validation cohort, showing an overall better performance than that of classical fetal laboratory parameters. Pathway analysis of the 34 peptides underlined the role of viral entry in fetuses with severe brain disease as well as the potential importance of both beta-2-microglobulin and adiponectin to protect the injured fetal brain infected with CMV. The results also suggested the mechanistic implication of the T calcium channel alpha-1G (CACNA1G) protein in the development of seizures in severely CMV infected children. These results open a new field for potential therapeutic options. In conclusion, this study demonstrates that amniotic fluid peptidome analysis can effectively predict the severity of congenital CMV infection. This

Here, we compared the amniotic fluid peptidome between asymptomatic fetuses who were born as asymptomatic neonates and symptomatic fetuses who were either terminated in view of severe cerebral lesions or born as severely symptomatic neonates. This comparison allowed us to identify a 34-peptide classifier in a discovery cohort of 13 symptomatic and 13 asymptomatic neonates. This classifier further yielded 89% sensitivity, 75% specificity and an area under the curve of 0.90 to segregate 9 severely symptomatic from 12 asymptomatic neonates in a validation cohort, showing an overall better performance than that of classical fetal laboratory parameters. Pathway analysis of the 34 peptides underlined the role of viral entry in fetuses with severe brain disease as well as the potential importance of both beta-2-microglobulin and adiponectin to protect the injured fetal brain infected with CMV. The results also suggested the mechanistic implication of the T calcium channel alpha-1G (CACNA1G protein in the development of seizures in severely CMV infected children. These results open a new field for potential therapeutic options. In conclusion, this study demonstrates that amniotic fluid peptidome analysis can effectively predict the severity of congenital CMV

    Background Congenital cytomegalovirus (cCMV) infection contributes to considerable long-term sequelae in neonates and children all over the world. The association between viral genotypes and severity of clinical cytomegalovirus (CMV) infection is yet to be defined. The objective of this study was to find the impact of active CMV infection during pregnancy and the clinical significance of genotypes in neonates with congenital cytomegalovirus infections in Pakistan. Methods A total of 409 blood samples from pregnant women seeking health care services at the two antenatal hospitals of Islamabad during January to December 2012 were tested by ELISA and nested-PCR. Pregnant women with active infection (detected as IgM positive, PCR positive or positive on both assays) were followed until delivery, to detect the outcome of overt cCMV infection in neonates. Genetic characterization of CMV strains was performed by sequence analysis of envelope glycoproteins: gB, gN and gH to detect the contributing CMV genotypes. Results The seroprevalence of anti-CMV IgG and IgM was 97.5% (399 out of 409) and 12.7% (52 out of 409), respectively, while 20% (82/409) pregnant women were found positive for CMV DNA by PCR. Logistic regression analysis showed a significant association of active infection with parity [OR = 2.56, 95% CI = 1.82–2.62, p = 0.04], febrile illness [OR = 1.84, 95% CI = 1.76–3.65, p = 0.01] and jaundice [OR = 22.5, 95% CI = 4.53–85.02, p = 0.002]. We were able to isolate virus in 41 out of 70 neonates; 36.6% (15 out of 41) of them were symptomatic at birth while 63.4% (26 out of 41) were asymptomatic. The most prominent clinical feature observed in symptomatic neonates was hepatosplenomegaly (26.6%; 4 out of 15). All three genotypes gB, gN and gH were found with the highest frequency of gB1 genotype, found in 75% infants with hepatic damage. Phylogenetic analysis of Pakistani strains showed 96%-100% homology to their prototype strains. Conclusions Active CMV

    Defects in dystroglycan glycosylation are associated with a group of muscular dystrophies, termed dystroglycanopathies, that include Fukuyama congenital muscular dystrophy (FCMD). It is widely believed that abnormal glycosylation of dystroglycan leads to disease-causing membrane fragility. We previously generated knock-in mice carrying a founder retrotransposal insertion in fukutin, the gene responsible for FCMD, but these mice did not develop muscular dystrophy, which hindered exploring ther...

    Human cytomegalovirus (HCMV) is the leading cause of congenital viral infection and mental retardation. HCMV infection, while causing asymptomatic infections in most immunocompetent subjects, can be transmitted during pregnancy from the mother with primary (and also recurrent) infection to the fetus. Hence, careful diagnosis of primary infection is required in the pregnant woman based on the most sensitive serologic assays (immunoglobulin M [IgM] and IgG avidity assays) and conventional virologic and molecular procedures for virus detection in blood. Maternal prognostic markers of fetal infection are still under investigation. If primary infection is diagnosed in a timely manner, prenatal diagnosis can be offered, including the search for virus and virus components in fetal blood and amniotic fluid, with fetal prognostic markers of HCMV disease still to be defined. However, the final step for definite diagnosis of congenital HCMV infection is detection of virus in the blood or urine in the first 1 to 2 weeks of life. To date, treatment of congenital infection with antiviral drugs is only palliative both prior to and after birth, whereas the only efficacious preventive measure seems to be the development of a safe and immunogenic vaccine, including recombinant, subunit, DNA, and peptide-based vaccines now under investigation. The following controversial issues are discussed in the light of the most recent advances in the field: the actual perception of the problem; universal serologic screening before pregnancy; the impact of correct counseling on decision making by the couple involved; the role of prenatal diagnosis in ascertaining transmission of virus to the fetus; the impact of preconceptional and periconceptional infections on the prevalence of congenital infection; and the prevalence of congenitally infected babies born to mothers who were immune prior to pregnancy compared to the number born to mothers undergoing primary infection during pregnancy.

    JC virus, a human papovavirus, is the causative agent of the demyelinating brain disease progressive multifocal leucoencephalopathy (PML). PML is a rare but fatal disease which develops as a complication of severe immunosuppression. Latent JC virus is harbored by many asymptomatic carriers and is transiently reactivated from the latent state upon immunosuppression. JC virus has a very restricted host range, with human glial cells being the only tissue in which it can replicate at reasonable efficiency. Evidence that latent human cytomegalovirus is harbored in the kidney similar to latent JC virus led to the speculation that during episodes of impaired immunocompetence, cytomegalovirus might serve as helper virus for JC virus replication in otherwise nonpermissive cells. We show here that cytomegalovirus infection indeed leads to considerable JC virus DNA replication in cultured human fibroblasts that are nonpermissive for the replication of JC virus alone. Cytomegalovirus-mediated JC virus replication is dependent on the JC virus origin of replication and T antigen. Ganciclovir-induced inhibition of cytomegalovirus replication is associated with a concomitant inhibition of JC virus replication. These results suggest that reactivation of cytomegalovirus during episodes of immunosuppression might lead to activation of latent JC virus, which would enhance the probability of subsequent PML development. Ganciclovir-induced repression of both cytomegalovirus and JC virus replication may form the rational basis for the development of an approach toward treatment or prevention of PML.

    A 4-year-old girl was referred for evaluation for a mild but persistent serum aspartate aminotransferase (AST) elevation detected incidentally during routine blood screening for a skin infection. Serum creatine kinase activity was found to be increased. Immuno-histochemical study for dystrophin in her muscle biopsy showed results consistent with a carrier state for muscular dystrophy. Molecular work-up showed the proposita to be a carrier of a deletion mutation of exon 48 of the dystrophin gene. Four male relatives also had the deletion mutation, yet showed no clinical symptoms of muscular dystrophy (age range 8-58 yrs). Linkage analysis of the dystrophin gene in the family showed a spontaneous change of an STR45 allele, which could be due to either an intragenic double recombination event, or CA repeat length mutation leading to identical size alleles. To our knowledge, this is the first documentation of an asymptomatic dystrophinopathy in multiple males of advanced age. Based on molecular findings, this family would be given a diagnosis of Becker muscular dystrophy. This diagnosis implies the development of clinical symptoms, even though this family is clearly asymptomatic. This report underscores the caution which must be exercised when giving presymptomatic diagnoses based on molecular studies. 28 refs., 4 figs., 1 tab.

    Abstract Cytomegalovirus (CMV) infections occur worldwide and primary infection usually occurs in early childhood and is often asymptomatic whereas primary infection in adults may result in symptomatic illness. CMV establishes a chronic latent infection with intermittent periods of reactivation. Primary infection or reactivation associate with increased mortality and morbidity in those who are immunocompromised. Transplacental transmission may result in significant birth defects or long-term sensorineural hearing loss. We performed a study to determine the CMV seroprevalence and the association between HLA Class I alleles and frequency of CMV infection in Ireland. The presence of CMV IgG, a marker of previous CMV infection, was determined for a cohort of 1849 HLA typed solid organ transplant donors between 1990 and 2013. The presence of CMV IgG was correlated with HLA type. The CMV seroprevalence in solid organ transplant donors was 33.4% (range 22–48% per annum) over the time period 1990 to 2013. Multivariate logistic regression analysis showed that both age and HLA alleles were associated with CMV seropositivity. A significant and positive relationship between age and CMV seropositivity was observed (OR = 1.013, P HLA-A1, HLA-A2, and HLA-A3 in our cohort were 40.8%, 48.8%, and 25.9%, respectively. Logistic regression analysis showed that the presence of HLA-A1 but not HLA-A2 or HLA-A3 was independently associated with CMV seronegativity (P HLA-A2 and HLA-A3 alleles were significantly more likely to be CMV seropositive (P HLA-B5, HLA-B7, and HLA-B8 in our cohort were 6.1%, 31.2%, and 30.8%, respectively. The presence of the most common inherited haplotype in the Irish population, HLA-A1, B8 was significantly associated with CMV seronegativity (OR = 1.278, P HLA-A1 in the Irish population may, in part, have a role in the reduced susceptibility to CMV infection.

    International Nuclear Information System (INIS)

    Chemical manifestations are considered and CT-semiotics of congenital toxoplasmosis, which can form intracranial calcinates, is described. Taking a certain case of congenital toxoplasmosis observation as an example the potentialities and significance of X-ray computerized tomography (CT) in the identification of brain pathological changes are demonstrated. It is shown that intracranial calcificates may be a sign of toxoplasmosis infection. In case of cytomegalovirus infection the calcificates on CT-scans have mostly periventricular localization. Equally with the revealing of brain status in case of chronic stage of neutrotoxoplasmosis the CT has also played a decisive role in diagnosis of pseudotumoroseus course of ischemic insult

    Smaill, Fiona

    2007-06-01

    Screening for asymptomatic bacteriuria is a standard of obstetrical care and is included in most antenatal guidelines. There is good evidence that treatment of asymptomatic bacteriuria will decrease the incidence of pyelonephritis. All pregnant women should be screened for asymptomatic bacteriuria, and there are no new data that would indicate otherwise. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of preterm delivery or low birth weight, but the methodological quality of the studies means any conclusion about the strength of this association needs to be drawn cautiously. A better understanding of the mechanism by which treatment of asymptomatic bacteriuria could prevent preterm delivery is needed. While several rapid screening tests have been evaluated, none perform adequately to replace urine culture for detecting asymptomatic bacteriuria. Until there are data from well-designed trials that establish the optimal duration of therapy for asymptomatic bacteriuria, standard treatment courses are recommended. PMID:17347050

    胎儿中枢神经系统(central nervous system,CNS)是人类巨细胞病毒(human cytomegalovirus,HCMV)先天性感染的主要靶器官.胚胎期CMV感染常常导致严重CNS畸形的发生,其前提条件是CNS中的神经前体(干)细胞、神经元及神经胶质细胞对CMV普遍易感.发育期CNS感染CMV具有以下特点:(1)神经系统细胞对CMV的容纳性在CNS的不同发育阶段有所不同;(2)受累的细胞数随着发育的进展而增多;(3)CNS不同部位的细胞对CMV的敏感性存在明显的差异;(4)感染发生时细胞所处细胞周期的时相也与感染严重程度密切相关.CMV感染能诱导宿主细胞特异性的染色体折断,影响Homeobox基因(胚胎发育的主控基因)的表达,进而阻断细胞周期(G1期滞留)、诱导细胞凋亡,导致CNS细胞数量减少与迁徙异常,最终导致CNS发育畸形.

  9. Congenital hypothyroidism presenting with postpartum bradycardia

    International Nuclear Information System (INIS)

    Congenital hypothyroidism is a clinical condition characterized by lack of thyroid hormone because of thyroid gland developmental and thyroid hormone biosynthesis disorders. The most common cause of permanent hypothyroidism is congenital factors. Prompt diagnosis is critical. However, overt signs of hypothyroidism are rarely present at birth, and 95% of affected babies are asymptomatic. Hypoxemia, apnea, acidosis, increased intracranial pressure, vagal stimulus and central nerve system abnormalities represent the most common causes of bradycardia in the neonate. Bradycardia associated with congenital hypothyroidism is very rare. In this paper, a case of severe congenital hypothyroidism, induced by maternal blocker antibodies, who presented with bradycardia, is reported. (author)

    To study the neuropathologic changes and CT manifestations in congenital TORCH infection of the brain. Analysis of 7 cases of congenital TORCH infection of the neonates and infants demonstrated by serum examination was performed. There were congenital toxoplasmosis 3 cases, congenital syncytial virus infection 1 case, congenital rubella virus infection 1 case, congenital cytomegalovirus infection 2 cases, and congenital herpes simplex virus infection 1 case. Cerebral hypoplasia, ventricular dilatation or hydrocephalus, subependymal and parenchymal calcifications, microcephalic focal cortical migration anomalies, schizencephaly polymicrogyria, et al, were demonstrated by CT with congenital TORCH infection. The earlier the infection, the more severe the brain developmental anomalies. The extent and appearance of calcification in brain were related to the degree, extent and course of TORCH infection. Basal ganglia calcification of unknown cause in infant was suggestive of congenital TORCH infection. Typical CT manifestations together with clinical picture may suggest congenital TORCH infection, while serological test can be diagnostic

    Human cytomegalovirus (HCMV), a ubiquitous herpesvirus, is the main cause of congenital abnormalities and mental retardation in newborns and is also responsible for severe life-threatening complications in immunocompromised individuals, including AIDS patients and transplant recipients. The disorders generated by cytomegalovirus are closely associated with the competence of the host immune system and both humoral and cell-mediated mechanisms are involved in the response to viral infection. To identify viral proteins recognized by host antibody responses, a cytomegalovirus genome library was created and displayed on lambda bacteriophage. The challenge of such a library with sera from individuals with congenital or acquired infection allowed the identification of a wide panel of recombinant bacteriophages carrying cytomegalovirus B cell epitopes. Epitope-containing fragments within the families of tegument proteins (pUL25, pUL32), structural proteins (pUL48, pUL56) and glycoproteins (pUL55) were identified. Moreover, library screening permitted isolation of phage clones carrying an antigenic region of an uncharacterized HCMV protein encoded by the UL71 open reading frame (ORF), highlighting the potential of lambda display technology in antigen and epitope discovery.

  16. Asymptomatic uterine fibroids.

    Science.gov (United States)

    Divakar, Hema

    2008-08-01

    It is estimated that at least 50% of fibroids are asymptomatic, but this figure is likely to be an underestimate as it is based on women in whom fibroids are found incidentally during another procedure (e.g. cervical screening), and there is little, if any, data from population studies on the true incidence of fibroids. If a prevalence of 50% by 50 years of age is accepted, a large number of women have asymptomatic fibroids. Working on the cliché, 'if it ain't broken, don't fix it', it may seem surprising that there should be a chapter dedicated to the issue of asymptomatic fibroids, since the simplistic approach might be to leave the asymptomatic fibroids well alone. However, asymptomatic fibroids may become symptomatic in the future, so it may be wiser to treat fibroids before they grow to a size when they become symptomatic, or treatment becomes more challenging, especially in young women who may desire fertility at a later stage, and in view of the fact that many women are starting their families in their mid-thirties when they have a 30% chance of having a fibroid(s). Despite their common occurrence, fibroids are still poorly understood. It is not known why they form in the first place, what determines their number and ultimate size, the best treatment approaches, or the factors that determine which women develop symptoms. Even when women present with disorders such as infertility, pelvic pain and abnormal bleeding, it is not always possible to be certain that a given myoma is not simply an innocent bystander rather than the cause of the symptom. This chapter addresses the challenging issue of what to do when fibroids are diagnosed incidentally. Firstly, there is the need to ascertain that the pelvic mass palpated is indeed a fibroid, and not an early, more sinister tumour, especially if conservative management is adopted. In addition, there is the issue of size, position and potential for becoming symptomatic at a later date. With the availability of uterine

    Cytomegalovirus infection is a frequent complication after transplantation. This infection occurs due to transmission from the transplanted organ, due to reactivation of latent infection, or after a primary infection in seronegative patients and can be defined as follows: latent infection, active infection, viral syndrome or invasive disease. This condition occurs mainly between 30 and 90 days after transplantation. In hematopoietic stem cell transplantation in particular, infection usually occurs within the first 30 days after transplantation and in the presence of graft-versus-host disease. The major risk factors are when the recipient is cytomegalovirus seronegative and the donor is seropositive as well as when lymphocyte-depleting antibodies are used. There are two methods for the diagnosis of cytomegalovirus infection: the pp65 antigenemia assay and polymerase chain reaction. Serology has no value for the diagnosis of active disease, whereas histology of the affected tissue and bronchoalveolar lavage analysis are useful in the diagnosis of invasive disease. Cytomegalovirus disease can be prevented by prophylaxis (the administration of antiviral drugs to all or to a subgroup of patients who are at higher risk of viral replication) or by preemptive therapy (the early diagnosis of viral replication before development of the disease and prescription of antiviral treatment to prevent the appearance of clinical disease). The drug used is intravenous or oral ganciclovir; oral valganciclovir; or, less frequently, valacyclovir. Prophylaxis should continue for 90 to 180 days. Treatment is always indicated in cytomegalovirus disease, and the gold-standard drug is intravenous ganciclovir. Treatment should be given for 2 to 3 weeks and should be continued for an additional 7 days after the first negative result for viremia. PMID:26222822

  3. Asymptomatic ischemic cerebral lesions

    International Nuclear Information System (INIS)

    For the purpose of studying the incidence, pathomorphology and etiology of asymptomatic ischemic cerebral lesions, we carried out a brain MRI study on 65 patients with diabetes mellitus accompanied with hypertension who are thought to belong to a high risk group of ischemic cerebrovascular diseases. Excluding the abnormality of tendon reflex due to diabetic neuropathy, sixty percent of the total patients had some mild neurological signs and symptoms, most of them was discrepancy in tendon reflex. The percentage of the patients in whom MRI disclosed some abnormalities was as high as 70%, they were lacunar stroke, multiple lacunar state, cortical infarct, and patchy high signal lesions visible only in the T2 weighted image. Lacunes or these patchy high signal lesions (considered to be the dilatation of the perivascular space or true lacunes) tended to be found along the border zone or the terminal zone. These results indicate that asymptomatic patients in whom MRI discloses the abnormalities should be considered as candidates for the future onset of multi-infarct. (author)

    Cytomegalovirus (CMV) infection is highly prevalent worldwide and can cause serious disease among immunocompromised individuals, including persons with HIV and transplant recipients on immunosuppressive therapies. It can also result in congenital cytomegalovirus when women are infected during pregnancy. Treatment and prevention of CMV in solid organ and haematopoietic stem cell transplant recipients is accomplished in one of three ways: (1) prophylactic therapy to prevent CMV viraemia; (2) pre-emptive therapy for those with low levels of replicating virus; and (3) treatment for established disease. Despite the high prevalence of CMV, there are few available approved drug therapies, and those that are available are hampered by toxicity and less-than-optimal efficacy. New therapies are being developed and tested; however, inconsistency in standardisation of virus levels and questions about potential endpoints in clinical trials present regulatory hurdles that must be addressed. This review covers the current state of CMV therapy, drugs currently under investigation, and clinical trial issues and questions that are in need of resolution. PMID:27482453

    The case is reported of a 39-year-old pregnant woman who presented with fever, abdominal complaints, and diarrhea. Laboratory investigation revealed mononucleosis in the peripheral blood. All microbiological studies were negative, with the exception of finding cytomegalovirus (CMV). Seroconversion was documented; the virus was cultured from urine and subsequently was demonstrated to be present in the inflamed mucosa of the rectum and distal sigmoid, which was found at sigmoidoscopy. This woman was delivered of a neonate with congenital CMV infection but without apparent malformations. The patient experienced recurrences of the bowel disease, in the first of which CMV could still be cultured from a biopsy specimen. In the follow-up period, an otherwise aspecific chronic inflammatory bowel disease remained present. No immunological abnormalities were found, and antibodies to human immunodeficiency virus were negative. This case demonstrates that inflammatory bowel disease can develop as a result of primary infection with CMV. PMID:2166491

    Congenital thrombophilia is a thrombotic diathesis caused by a variety of genetic abnormalities in blood coagulation factors or their inhibitory factors associated with physiological thrombus formation. Patients with congenital thrombophilia often present with unusual clinical episodes of venous thrombosis (occasionally combined with pulmonary embolism, known as venous thromboembolism) at a young age and recurrence in atypical vessels, such as the mesenteric vein and superior sagittal sinus, often with a family history of this condition. Studies in Japan as well as in western countries have shown congenital thrombophilia to be caused by a wide variety of genetic abnormalities in natural anticoagulant proteins, such as antithrombin, protein C, and protein S. However, there may still be many unknown causes of hereditary thrombosis. We recently reported a case of hereditary thrombosis induced by a novel mechanism of antithrombin resistance, that is, congenital thrombophilia caused by a gain-of-function mutation in the gene encoding the coagulation factor prothrombin.

    Twenty-five percent of cytomegalovirus (CMV)-infected fetuses had sequelae and 8% of those in the recurrent-infected group had sequelae. There is no report yet on the fetal therapy for CMV infections. A Japanese pregnant woman with intrauterine fetal CMV infection diagnosed at 26 weeks of pregnancy is presented. CMV culture of amniotic fluid was positive. A CMV DNA assay using the polymerase chain reaction method of the cord blood and the amniotic fluid was positive during the pregnancy; however, testing for fetal serum CMV-specific IgM was negative. The CMV IgG titer of fetal serum at 27 weeks of pregnancy was a third of that of the maternal serum. CMV hyperimmunoglobulin was injected into the fetal abdominal cavity at 28 and 29 weeks of pregnancy. A second administration of CMV hyperimmunoglobulin increased the titer of CMV IgG in the fetal circulation. At birth, the urine culture was positive for CMV. However, CMV DNA of the ascites became negative. A brain CT scan performed 2 weeks after birth revealed some small calcifications beside the right ventricle. CMV hyperimmunoglobulin injection to the fetal abdominal cavity has been shown to increase the IgG in the fetal serum. This is the first report of fetal therapy of congenital CMV infection.

    Background Congenital cytomegalovirus infections are a leading cause of neurodevelopmental disorders in human and represent a major health care and socio-economical burden. In contrast with this medical importance, the pathophysiological events remain poorly known. Murine models of brain cytomegalovirus infection, mostly neonatal, have brought recent insights into the possible pathogenesis, with convergent evidence for the alteration and possible involvement of brain immune cells. Objectives and Methods In order to confirm and expand those findings, particularly concerning the early developmental stages following infection of the fetal brain, we have created a model of in utero cytomegalovirus infection in the developing rat brain. Rat cytomegalovirus was injected intraventricularly at embryonic day 15 (E15) and the brains analyzed at various stages until the first postnatal day, using a combination of gene expression analysis, immunohistochemistry and multicolor flow cytometry experiments. Results Rat cytomegalovirus infection was increasingly seen in various brain areas including the choroid plexi and the ventricular and subventricular areas and was prominently detected in CD45low/int, CD11b+ microglial cells, in CD45high, CD11b+ cells of the myeloid lineage including macrophages, and in CD45+, CD11b– lymphocytes and non-B non-T cells. In parallel, rat cytomegalovirus infection of the developing rat brain rapidly triggered a cascade of pathophysiological events comprising: chemokines upregulation, including CCL2-4, 7 and 12; infiltration by peripheral cells including B-cells and monocytes at E17 and P1, and T-cells at P1; and microglia activation at E17 and P1. Conclusion In line with previous findings in neonatal murine models and in human specimen, our study further suggests that neuroimmune alterations might play critical roles in the early stages following cytomegalovirus infection of the brain in utero. Further studies are now needed to determine which

    Full Text Available Abstract Background Congenital cytomegalovirus (CMV infection is the most common congenital viral infection in humans and the major nonhereditary cause of central nervous system (CNS developmental disorders. Previous attempts to develop a murine CMV (MCMV model of natural congenital human CMV (HCMV infection have failed because MCMV does not cross the placenta in immunocompetent mice. Results In marked contrast with immunocompetent mice, C.B-17 SCID (severe combined immunodeficient mice were found to be highly susceptible to natural MCMV transplacental transmission and congenital infection. Timed-pregnant SCID mice were intraperitoneally (IP injected with MCMV at embryonic (E stages E0-E7, and vertical MCMV transmission was evaluated using nested polymerase chain reaction (nPCR, in situ hybridization (ISH and immunohistochemical (IHC assays. SCID mouse dams IP injected at E0 with 102 PFU of MCMV died or resorbed their fetuses by E18. Viable fetuses collected at E18 from SCID mice IP injected with 102–104 PFU of MCMV at E7 did not demonstrate vertical MCMV transmission. Notably, transplacental MCMV transmission was confirmed in E18 fetuses from SCID mice IP injected with 103 PFU of MCMV at stages E3-E5. The maximum rate of transplacental MCMV transmission (53% at E18 occurred when SCID mouse dams were IP injected with 103 PFU of MCMV at E4. Congenital infection was confirmed by IHC immunostaining of MCMV antigens in 26% of the MCMV nPCR positive E18 fetuses. Transplacental MCMV transmission was associated with intrauterine growth retardation and microcephaly. Additionally, E18 fetuses with MCMV nPCR positive brains had cerebral interleukin-1α (IL-1α expression significantly upregulated and cerebral IL-1 receptor II (IL-1RII transcription significantly downregulated. However, MCMV-induced changes in cerebral cytokine expression were not associated with any histological signs of MCMV infection or inflammation in the brain. Conclusion Severe T

    Full Text Available Congenital syphilis is a severe, disabling infection that occurs due to the transmission of Treponema pallidum across the placenta during pregnancy or from contact with an infectious genital lesion during delivery. However, its early diagnosis is often difficult because more than half of the affected infants are asymptomatic, and the signs in symptomatic infants may be subtle and nonspecific. Although its incidence is declining, this long-forgotten disease continues to affect pregnant women, resulting in considerable perinatal morbidity and mortality. We hereby report a case of a 2-month-old infant with early congenital syphilis presenting with joint swellings and Parrot′s pseudoparalysis, a comparative rarity in the present scenario. The report also stresses upon the importance of implementing the Centres for Disease Control and Prevention recommendation that all the pregnant women should be screened for syphilis in the first antenatal visit in the first trimester and again in late pregnancy.

    2013-01-01

    Full Text Available Fetal and neonatal infections caused by human cytomegalovirus (CMV are important causes of morbidity and occasional mortality. Development of a vaccine against congenital CMV infection is a major public health priority. Vaccine design is currently focused on strategies that aim to elicit neutralizing antibody and T-cell responses, toward the goal of preventing primary or recurrent infection in women of child-bearing age. However, there has been relatively little attention given to understanding the mechanisms of immune protection against acquisition of CMV infection in the fetus and newborn and how this information might be exploited for vaccine design. There has similarly been an insufficient study of what deficits in the immune response to CMV, both for mother and fetus, may increase susceptibility to congenital infection and disease. Protection of the fetus against vertical transmission can likely be achieved by protection of the placenta, which has its own unique immunological milieu, further complicating the analysis of the correlates of protective immunity. In this review, the current state of knowledge about immune effectors of protection against CMV in the maternal, placental, and fetal compartments is reviewed. A better understanding of immune responses that prevent and/or predispose to infection will help in the development of novel vaccine strategies.

Although pectus excavatum, pectus carinatum, and cleft sternum can present as isolated deformity, in most cases they are associated with heart and inner organs anomalies and described as symptoms of syndromes like Marfan syndrome, Noonan syndrome, Poland anomaly, and Cantrell pentalogy. In contrast, the etiology of an isolated defect is not well understood. We observed a short sternum (dysmorphic manubrium, hypoplastic body, and complete absence of the xiphoid process in a completely asymptomatic 13-year-old woman. A comprehensive instrumental exams panel was performed to exclude associated anomalies of the heart and of the other organ systems. The patient was completely asymptomatic and she did not need any medical or surgical treatment. To our knowledge, this is the first case of isolated short sternum reported in literature.

In such cases, a rapid viral detection is crucial for monitoring the clinical outcome and the antiviral treatment. In this study, we optimized a sensitive biplex TaqMan® real-time PCR for the simultaneous detection and differentiation of a partial HCMV UL97 sequence and homologous extrinsic control (HEC) in the same tube. HEC was represented by a plasmid containing a modified HCMV sequence retaining the original primer binding sites, while the probe sequence was substituted by a phylogenetically divergent one (chloroplast CF0 subunit plant gene). It was estimated that the optimal HEC concentration, which did not influence the HCMV amplification is 1,000 copies/reaction. The optimized TaqMan® PCR demonstrated high analytical sensitivity (6.97 copies/reaction, CI = 95%) and specificity (100%). Moreover, the reaction showed adequate precision (repeatability, CV = 0.03; reproducibility, CV = 0.0027) and robustness (no carry-over or cross-contamination). The diagnostic sensitivity (100%) and specificity (97.8%) were adequate for the clinical application of the molecular platform. The optimized TaqMan® real-time PCR is suitable for HCMV detection and quantitation in predisposed patients and monitoring of the applied antiviral therapy. J. Med.

    Introduction: Pre-eclampsia is a pregnancy-specific disease characterized by hypertension after 20 weeks of gestation and proteinuria. It is a major cause of maternal and perinatal morbidity and mortality. The pathogenesis of pre-eclampsia is not completely understood. In our study we investigated if there is a potential link between cytomegalovirus infection and pre-eclampsia and if cytomegalovirus infection is the triggering factor of pre-eclampsia.

    Full Text Available Abstract Background Human cytomegalovirus (HCMV is the most prevalent congenital viral infection in the United States and Europe causing significant morbidity and mortality to both mother and child. HCMV is also an opportunistic pathogen in immunocompromised individuals, including human immunodeficiency virus (HIV- infected patients with AIDS, and solid organ and allogeneic stem cell transplantation recipients. Current treatments for HCMV-associated diseases are insufficient due to the emergence of drug-induced resistance and cytotoxicity, necessitating novel approaches to limit HCMV infection. The aim of this study was to develop therapeutic peptides targeting glycoprotein B (gB, a major glycoprotein of HCMV that is highly conserved across the Herpesviridae family, that specifically inhibit fusion of the viral envelope with the host cell membrane preventing HCMV entry and infection. Results Using the Wimley-White Interfacial Hydrophobicity Scale (WWIHS, several regions within gB were identified that display a high potential to interact with lipid bilayers of cell membranes and hydrophobic surfaces within proteins. The ability of synthetic peptides analogous to WWIHS-positive sequences of HCMV gB to inhibit viral infectivity was evaluated. Human foreskin fibroblasts (HFF were infected with the Towne-GFP strain of HCMV (0.5 MOI, preincubated with peptides at a range of concentrations (78 nm to 100 μM, and GFP-positive cells were visualized 48 hours post-infection by fluorescence microscopy and analyzed quantitatively by flow cytometry. Peptides that inhibited HCMV infection demonstrated different inhibitory concentration curves indicating that each peptide possesses distinct biophysical properties. Peptide 174-200 showed 80% inhibition of viral infection at a concentration of 100 μM, and 51% and 62% inhibition at concentrations of 5 μM and 2.5 μM, respectively. Peptide 233-263 inhibited infection by 97% and 92% at concentrations of 100

    Full Text Available Background: Asymptomatic bacteriuria is the significant presence of bacteria in the urine of an individual without symptoms. In pregnancy, the apparent reduction in immunity of pregnant women tends to encourage the growth of pathogens. Aim: This study was carried out to determine the prevalence of asymptomatic bacteriuria in pregnant women attending a primary health centre in Benin City, Nigeria. Materials and Methods: A total of 1,228 pregnant women were recruited for this study. All subjects were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine sample was collected from each patient into sterile universal container. The urine samples were examined microscopically and by cultural method. Identification of isolates was by standard microbiological technique. Result: A total of 556 (45.3% were positive for significant bacteriuria. There was a significant difference in the prevalence of asymptomatic bacteriuria with respect to age (P < 0.0001. Trimester did not show any significant difference (P = 0.2006 in the prevalence of asymptomatic bacteriuria. Escherichia coli was the most predominant organism followed closely by Staphylococcus aureus. Ciprofloxacin, Ceftriaxone and Augmentin were found to be the most effective antibiotics against the urinary isolates. Conclusion: Asymptomatic bacteriuria is not uncommon among antenatal patients in the population studied. Routine urine cultural test should be carried out on all antenatal patients in order to identify any unsuspecting infection. This measure will go a long way in reducing maternal and obstetric complications associated with pregnancy.

  13. Asymptomatic Bacteriuria and Bacterial Interference.

    2015-10-01

    Asymptomatic bacteriuria is very common. In healthy women, asymptomatic bacteriuria increases with age, from asymptomatic bacteriuria, irrespective of age or gender. The prevalence is very high in residents of long-term-care facilities, from 25% to 50% of women and 15% to 40% of men. Escherichia coli is the most frequent organism isolated, but a wide variety of other organisms may occur. Bacteriuria may be transient or persist for a prolonged period. Pregnant women with asymptomatic bacteriuria identified in early pregnancy and who are untreated have a risk of pyelonephritis later in pregnancy of 20% to 30%. Bacteremia is frequent in bacteriuric subjects following mucosal trauma with bleeding, with 5% to 10% of patients developing severe sepsis or septic shock. These two groups with clear evidence of negative outcomes should be screened for bacteriuria and appropriately treated. Asymptomatic bacteriuria in other populations is benign and screening and treatment are not indicated. Antimicrobial treatment has no benefits but is associated with negative outcomes including reinfection with antimicrobial resistant organisms and a short-term increased frequency of symptomatic infection post-treatment. The observation of increased symptomatic infection post-treatment, however, has led to active investigation of bacterial interference as a strategy to prevent symptomatic episodes in selected high risk patients.

    Congenital triangular alopecia (CTA) also known as temporal triangular alopecia is a benign noncicatricial pattern of hair loss. It typically affects the frontotemporal region and rarely involves the temporoparietal or occipital scalp. It is a nonprogressive disorder that presents as a triangular, oval or lancet-shaped patch of alopecia. CTA can manifest at birth or develop later in life. The exact etiology of this condition remains unknown. Rarely, it may be associated with other disorders such as Down's syndrome and phakomatosis pigmentovascularis. The diagnosis is based on its distinct clinical appearance. Histologically, hair follicles are miniaturized and replaced by sparse vellus hair follicles. Tricoscopy using a polarized light handheld dermatoscope can be a useful diagnostic tool. CTA is often asymptomatic and remains unchanged throughout the life. No treatment is required. Surgical intervention with follicular unit hair transplantation can provide a satisfactory cosmetic result. In this paper, we have identified 126 cases of CTA in the published literature cited on PubMed between 1905 and 2015. From the available evidence, 79% of patients with CTA presented with unilateral hair loss, 18.5% with bilateral involvement and rarely, with occipital alopecia (2.5%). There was no gender predilection. These figures are entirely consistent with previously published data. Physicians should remember to consider CTA as a potential diagnosis in any patient presenting with a nonscarring alopecia in order to avoid unnecessary investigations and treatments. PMID:26180448

    In recent years, marked increase in incidence of congenital syphilis has occurred throughout the world due to changes in social norms and development of penicillin-resistant strains. Early diagnosis plays an important role in congenital syphilis as the clinical manifestations may simulate many other conditions in the paediatric age group. The authors analyzed 52 cases of congenital syphilis admitted to the department of paediatrics, Chosun University Hospital, clinically and radiologically. Among them, 18 cases were born in this hospital and 34 cases were admitted from OPD, during the period of 8 years from January, 1975 to December, 1982. The results obtained were as follows; 1. In 28 of 34 cases (82%), the first clinical manifestations were below the age of 3 months. 2. Among the 52 cases, a male predominance was observed with a male to female ratio of 2 : 1. 3. The serologic test (VDRL) of the 52 studied cases showed reactive response in 49 cases (94%), and that of syphilitic mothers except 6 cases, reactive in all studied cases. 4. The major manifestations of the 52 cases were bone tenderness (12%) and swelling of the joints (7%) in skeletal system, hepatosplenomegaly (79%) and skin lesions (73%) in extraskeletal one. 5. The radiological skeletal changes were detected in 45 of 52 cases (87%), and the commonest findings were detected in 45 of 52 cases (87%), and the commonest findings were metaphysitis (83%) and periostitis (81%). The most characteristic type of metaphysitis were transverse trophic line (74%) and zone of rarefaction (65%). 6. The commonest bones to be affected were growing metaphyses of the long bones, particulary about the wrist and the knee. The order of frequency were radius (80%), uina (80%), tibia (77%), femur (69%) and humerus (40%)

    Full Text Available Development of a vaccine against congenital infection with human cytomegalovirus is complicated by the issue of re-infection, with subsequent vertical transmission, in women with pre-conception immunity to the virus. The study of experimental therapeutic prevention of re-infection would ideally be undertaken in a small animal model, such as the guinea pig cytomegalovirus (GPCMV model, prior to human clinical trials. However, the ability to model re-infection in the GPCMV model has been limited by availability of only one strain of virus, the 22122 strain, isolated in 1957. In this report, we describe the isolation of a new GPCMV strain, the CIDMTR strain. This strain demonstrated morphological characteristics of a typical Herpesvirinae by electron microscopy. Illumina and PacBio sequencing demonstrated a genome of 232,778 nt. Novel open reading frames ORFs not found in reference strain 22122 included an additional MHC Class I homolog near the right genome terminus. The CIDMTR strain was capable of dissemination in immune compromised guinea pigs, and was found to be capable of congenital transmission in GPCMV-immune dams previously infected with salivary gland‑adapted strain 22122 virus. The availability of a new GPCMV strain should facilitate study of re-infection in this small animal model.

    Full Text Available OBJECTIVE: To report an infant with congenital cytomegalovirus and progressive sensorineural hearing loss, who was assessed by three methods of hearing evaluation. CASE DESCRIPTION: In the first audiometry, at four months of age, the infant showed abnormal response in Otoacoustic Emissions and normal Auditory Brainstem Response (ABR, with electrophysiological threshold in 30dBnHL, in both ears. With six months of age, he showed bilateral absence of the ABR at 100dBnHL. The behavioral observational audiometry was impaired due to the delay in neuropsychomotor development. At eight months of age, he was submitted to Auditory Steady State Response (ASSR and the thresholds were 50, 70, absent in 110 and in 100dB, respectively for 500, 1,000, 2,000 and 4,000Hz in the right ear, and 70, 90, 90 and absent in 100dB, respectively for 500, 1,000, 2,000 and 4,000Hz in the left ear. COMMENTS: In the first evaluation, the infant had abnormal Otoacoustic Emission and normal ABR, which became altered at six months of age. The hearing loss severity could be identified only by the ASSR, which allowed the best procedure for hearing aids adaptation. The case description highlights the importance of the hearing status follow-up for children with congenital cytomegalovirus.

    Full Text Available Most of the complications caused by asymptomatic bacteriuria (ABU in pregnancy can be avoided by early treatment. In our study, we aimed to determine the urinary infection prevalence and the pathogen agent identification in the pregnant women observing in our clinic. 240 asymptomatic pregnant women having no antibiotic treatment history during last 1 week and were enrolled to the study. Urine specimens were collected from 12th and 16th week pregnant women, and were examined by light microscope and cultured at the mediums. Demographic data belonging to the patients (age, birth number, abortion number were recorded. Mean age was assigned as 24, 49±2, 74 (20-31 years. 104 patients (43,3% were primipara, 94 patients (39.2% had previous pregnancy and 42 patients (17,5% were multipara. 19,2% of the patients (n=46 had an abortion history. Mean value of leucocyte levels among pregnant women was assigned as 10045 / mm3 (6750-15200. Although positive urine culture ratio was 12,5% (n=30 at first visit, it was 10% (n=30 in the 12th week. Urine culture in 16th week was determined as negative in all pregnant women. When agent pathogen was analyzed from urine culture, the most common isolated microorganism that causes asymptomatic bacteriuria (ABU was Escherichia coli with ratio of 83%(n=200. Asymptomatic bacteriuria (ABU is common in pregnancy and can cause serious maternal and fetal complications if it’s not treated on time and properly. Therefore; all pregnant women should be screened at first antenatal visit for asymptomatic bacteriuria (ABU as a routine program and medical treatment should be required at the positive cases.

    Full Text Available Over 90% of the world’s population acquires a cytomegalovirus (CMV infection. This infection, although asymptomatic or self-limiting, is a major burden to the immune system. For this reason, and because CMV immunization is possible, determining whether CMV can cause reduced longevity, particularly among those with coronary artery disease, is important and previous reports have been conflicting. Thus our objective was to assess the association between CMV infection as defined serologically and antibody levels against CMV and longterm survival (18 years. We completed a prospective observational cohort study of 915 consecutive patients (mean age 58 years undergoing coronary angiography. CMV immunoglobulin levels were measured at baseline using either a whole cell CMV antigen or a purified protein antigen (gB. After adjustment for potentially confounding variables (age, race, gender, body mass index, the presence or absence of coronary artery disease, the number of diseased vessels, diabetes, renal disease, hypertension, dialysis, congestive heart failure, and the maximum percent reduction in luminal diameter, Cox’s proportional hazards models showed no association between CMV seropositivity or levels of antibodies against CMV by either assay and longevity for both patients with or without coronary artery disease (CAD nor for those under or over 70 years of age at baseline. Our observations suggest that universal immunization against CMV may not improve longevity.

    Full Text Available bjective: Congenital hypothyroidism is characterized by inadequate thyroid hormone production in newborn infants. Many infants with CH have co-occurring congenital malformations. This is an investigation on the frequency and types of congenital anomalies in infants with congenital hypothyroidism born from May 2006-2010 in Hamadan, west province of Iran.Methods: The Iranian neonatal screening program for congenital hypothyroidism was initiated in May 2005. This prospective descriptive study was conducted in infants diagnosed with congenital hypothyroidism being followed up in Pediatric Endocrinology Clinicof Besat Hospital, a tertiary care centre in Hamadan. Cases included all infants with congenital hypothyroidism diagnosed through newborn screening program or detected clinically. Anomalies were identified by clinical examination, echocardiography, and X-ray of the hip during the infant’s first year of life.Results: A total of 150 infants with biochemically confirmed primary congenital hypothyroidism (72 females and 78 males were recruited during the period between May 2006-2010. Overall, 30 (20% infants had associated congenital anomalies. The most common type of anomaly was Down syndrome. Seven infants (3.1% had congenital cardiac anomalies such as: ASD (n=3, VSD (n=2, PS (n =1, PDA (n=1. Three children (2.6% had developmental displasia of the hip (n=3.Conclusion: The overall frequency of Down syndrome, cardiac malformation and other birth defect was high in infants with CH.

    Full Text Available Introduction: Congenital anomalies represent a significant cause of premature birth, of child morbidity and mortality. From 200000 new born per year, over 10000 presented malformations. Epidemiologic studies have shown that the incidence of malformations is increasing and varies upon geographic features, race and gender. Perinatal mortality is generated in 66.66% of cases by congenital malformations, illnesses from perinatal period and the rest of them is generated by the birth. Material and Method: The study was retrospective and was carried on for a period of five years (2003-2007 based on medical records and on laboratory results, (especially those for TORCH screening: toxoplasmosis, rubella, cytomegalovirus, and herpes virus. Results: Major structural anomalies were present at 39.51% (388 cases of 982 patients which were registered in Genetic Pathology Center from Pediatric Clinics I, Cluj-Napoca. Diagnosed abnormalities included: congenital malformations of circulatory, respiratory, digestive, central nervous system, congenital malformations of skeletal system, Down syndrome, which is consistent with results of other studies showing that the most common are heart abnormalities (33.06%, followed in descending order of frequency by urinary, genital, CNS, skin, oral-facial cleft and digestive anomalies. Conclusions: Early detection of major malformation during early pregnancy can indicate for medical termination of pregnancy to reduce the high morbidity and mortality of neonates due to congenital malformations. So proper and timely counselling, regular antenatal care with folate supplementation especially during the most sensitive period of embryogenesis is essential to avoid major congenital malformation for future pregnancy.

  10. Feeling manipulated: cytomegalovirus immune manipulation

    2009-01-01

    Full Text Available Abstract No one likes to feel like they have been manipulated, but in the case of cytomegalovirus (CMV immune manipulation, we do not really have much choice. Whether you call it CMV immune modulation, manipulation, or evasion, the bottom line is that CMV alters the immune response in such a way to allow the establishment of latency with lifelong shedding. With millions of years of coevolution within their hosts, CMVs, like other herpesviruses, encode numerous proteins that can broadly influence the magnitude and quality of both innate and adaptive immune responses. These viral proteins include both homologues of host proteins, such as MHC class I or chemokine homologues, and proteins with little similarity to any other known proteins, such as the chemokine binding protein. Although a strong immune response is launched against CMV, these virally encoded proteins can interfere with the host's ability to efficiently recognize and clear virus, while others induce or alter specific immune responses to benefit viral replication or spread within the host. Modulation of host immunity allows survival of both the virus and the host. One way of describing it would be a kind of "mutually assured survival" (as opposed to MAD, Mutually Assured Destruction. Evaluation of this relationship provides important insights into the life cycle of CMV as well as a greater understanding of the complexity of the immune response to pathogens in general.

    Full Text Available Congenital hypothyroidism (CH is the one of the most common preventable cause of mental retardation. In the majority of patients, CH is caused by an abnormal development of the thyroid gland (thyroid dysgenesis that is a sporadic disorder and accounts for 85% of cases and the remaining 15% of cases are caused by dyshormonogenesis. The clinical features of congenital hypothyroidism are so subtle that many newborn infants remain undiagnosed at birth and delayed diagnosis leads to the most severe outcome of CH, mental retardation, emphasizing the importance of neonatal screening. Dried capillary blood is used for screening and it is taken from heel prick optimally between 2 and 5 days of age. Blood spot TSH or thyroxine (T4 or both are being used for CH screening in different programs around the world. Neonates with abnormal thyroid screening tests should be recalled immediately for examination and a venipuncture blood sample should be drawn for confirmatory serum testing. Confirmatory serum should be tested for TSH and free T4, or total T4. Serum TSH and T4 undergo dynamic changes in the first weeks of life; it is important to compare serum results with age-normal reference ranges. Treatment should be started promptly and infant should be rendered euthyroid as early as possible, as there is an inverse relationship between intelligence quotient (IQ and the age at diagnosis. Levothyroxine (l-thyroxine is the treatment of choice and American academy of pediatrics and European society of pediatric endocrinology recommend 10-15μgm/kg/day as initial dose. The immediate goal of therapy is to normalize T4 within 2 weeks and TSH within one month. The overall goal of treatment is to ensure growth and neurodevelopmental outcomes as close as possible to their genetic potential.

    Congenital airway anomalies can be asymptomatic or may cause severe respiratory distress requiring immediate treatment. These anomalies can present early in life, or may be just incidental findings. It is important to recognize these entities to realize their clinical significance and to avoid false diagnosis. In this article, the various congenital airway anomalies and their imaging features by multidetector computed tomography (MDCT) are reviewed in order of occurrence during the embryological timeline. This pictorial essay reviews the various distinct congenital airway lesions and their MDCT manifestations. It also provides insight into the embryological basis of the congenital airway lesions encountered. PMID:22224177

    Full Text Available Abstract Background The morbidity and mortality associated with cytomegalovirus (CMV infection in immunocompromised patients (especially in HIV-infected patients and transplant recipients, as well as with congenital CMV infection are well known. In contrast, relatively little attention has been paid to the morbidity and mortality that CMV infection may cause in immunocompetent patients. Methods We reviewed the evidence associated with severe manifestations of CMV infection in apparently immunocompetent patients and the potential role of antiviral treatment for these infections. We searched in PubMed, Scopus, and the Cochrane Library for the period of 1950–2007 to identify relevant articles. Results We retrieved 89 articles reporting on severe CMV infection in 290 immunocompetent adults. Among these reports, the gastrointestinal tract (colitis and the central nervous system (meningitis, encephalitis, transverse myelitis were the most frequent sites of severe CMV infection. Manifestations from other organ-systems included haematological disorders (haemolytic anaemia, thrombocytopenia, thrombosis of the venous or arterial vascular system, ocular involvement (uveitis, and lung disease (pneumonitis. The clinical practice reported in the literature has been to prescribe antiviral treatment for the most severe manifestations of monophasic meningoencephalitis (seizures and coma, ocular involvement, and lung involvement due to CMV. Conclusion Severe life-threatening complications of CMV infection in immunocompetent patients may not be as rare as previously thought.

  14. Prevention of maternal-fetal transmission of cytomegalovirus.

    2013-12-01

    Reported maternal-to-fetal rates of primary cytomegalovirus (CMV) infection during pregnancy have been between 30% and 50%. The highest rate of symptomatic congenital infection and sequelae occurs in about 25% of infected infants born of mothers with a primary infection during pregnancy. Symptomatic infants demonstrate a constellation of clinical features that reflect placental dysfunction and probable viral infection of the central nervous system of the fetus. In the United States, we estimate that about 8000 affected infants are born each year. Two options may be available to prevent or treat maternal CMV infection during pregnancy, especially for women with exposure to young children in the home. The first is hygienic intervention. Two studies support the simplicity, harmlessness, and effectiveness of hygienic intervention to prevent child-to-mother transmission of CMV among high-risk pregnant women who know they are susceptible. The second is CMV immunoglobulin. A meta-analysis of 2 clinical trials showed an efficacy of 50% if immunoglobulin is given to pregnant women who have acquired a primary CMV infection during pregnancy. These results mean that seronegative pregnant women have options to prevent fetal infection. PMID:24257425

    Human cytomegalovirus (HCMV) is a prevalent virus that infects up to 90% of the population. The goal of this research is to determine if small molecular prodrug substrates can be developed for a specific HCMV encoded protease and thus achieve site-specific activation. HCMV encodes a 256 amino acid serine protease that is responsible for capsid assembly, an essential process for herpes virus production. The esterase activity of the more stable HCMV A143T/A144T protease mutant was evaluated with model p-nitrophenol (ONp) esters, Boc-Xaa-ONp (Ala, Leu, Ile, Val, Gln, Phe at the Xaa position). We demonstrate that the A143T/A144T mutant has esterase activity toward specific small ester compounds, e.g., Boc-L-Ala-ONp. Mono amino acid and dipeptide prodrugs of ganciclovir (GCV) were also synthesized and evaluated for hydrolysis by the A143T/A144T protease mutant in solution. Hydrolysis of these prodrugs was also evaluated in Caco-2 cell homogenates, human liver microsomes (HLMs), and rat and human plasma. For the selectivity potential of the prodrugs, the hydrolysis ratio was evaluated as a percentage of prodrug hydrolyzed by the HCMV protease over the percentages of prodrug hydrolyses by Caco-2 cell homogenates, HLMs, and human/rat plasma. A dipeptide prodrug of ganciclovir, Ac-l-Gln-l-Ala-GCV, emerged as a potential selective prodrug candidate. The results of this research demonstrate that targeting prodrugs for activation by a specific protease encoded by the infectious HCMV pathogen may be achievable. PMID:23485093

    Human cytomegalovirus (CMV) is purportedly present in glioblastoma (GBM) while absent from the normal brain, making CMV antigens potentially ideal immunological anti-GBM targets. We recently demonstrated that patient-derived CMV pp65-specific T cells are capable of recognizing and killing autologous GBM tumor cells. This data supports CMV antigen-directed immunotherapies against GBM.

  19. Congenital hypothyroidism

    Directory of Open Access Journals (Sweden)

    LaFranchi Stephen H

    2010-06-01

    Full Text Available Abstract Congenital hypothyroidism (CH occurs in approximately 1:2,000 to 1:4,000 newborns. The clinical manifestations are often subtle or not present at birth. This likely is due to trans-placental passage of some maternal thyroid hormone, while many infants have some thyroid production of their own. Common symptoms include decreased activity and increased sleep, feeding difficulty, constipation, and prolonged jaundice. On examination, common signs include myxedematous facies, large fontanels, macroglossia, a distended abdomen with umbilical hernia, and hypotonia. CH is classified into permanent and transient forms, which in turn can be divided into primary, secondary, or peripheral etiologies. Thyroid dysgenesis accounts for 85% of permanent, primary CH, while inborn errors of thyroid hormone biosynthesis (dyshormonogeneses account for 10-15% of cases. Secondary or central CH may occur with isolated TSH deficiency, but more commonly it is associated with congenital hypopitiutarism. Transient CH most commonly occurs in preterm infants born in areas of endemic iodine deficiency. In countries with newborn screening programs in place, infants with CH are diagnosed after detection by screening tests. The diagnosis should be confirmed by finding an elevated serum TSH and low T4 or free T4 level. Other diagnostic tests, such as thyroid radionuclide uptake and scan, thyroid sonography, or serum thyroglobulin determination may help pinpoint the underlying etiology, although treatment may be started without these tests. Levothyroxine is the treatment of choice; the recommended starting dose is 10 to 15 mcg/kg/day. The immediate goals of treatment are to rapidly raise the serum T4 above 130 nmol/L (10 ug/dL and normalize serum TSH levels. Frequent laboratory monitoring in infancy is essential to ensure optimal neurocognitive outcome. Serum TSH and free T4 should be measured every 1-2 months in the first 6 months of life and every 3-4 months thereafter

    Background.  Congenital cytomegalovirus (CMV) infection can cause severe birth defects. The majority of children with congenital CMV are born to CMV-seropositive women; however, transmission from mother to fetus and resulting defects are more likely to occur when mothers experience seroconversion during pregnancy. The objective of this study was to provide a population-based estimate of CMV seropositivity and to identify factors that correlate with the detection of CMV-immunoglobulin (Ig)G antibodies. Methods.  Cytomegalovirus-specific IgG antibodies were determined by enzyme-linked immunosorbent assay in 13 876 serum samples from children and adolescents (aged 1-17 years). Cytomegalovirus seroprevalence was correlated with children's age, gender, migration background, country of origin, place of birth, socioeconomic status, breast feeding, daycare attendance, order and number of siblings, and residence in East versus West Germany. Results.  Age-adjusted seroprevalence was 27.4% (95% confidence interval, 25.8-29.0). Cytomegalovirus seroprevalence increased with age (21.5% at ages 1-2; 32.0% at ages 14-17). Cytomegalovirus seropositivity was significantly associated with migration background, country of origin and place of birth, and (among migrants only) with low socioeconomic status. Risk factors for CMV acquisition included the birth order of siblings, breastfeeding, early daycare attendance, and living in East Germany. Conclusions.  In Germany, CMV seroprevalence increases with age, irrespective of gender. These data highlight risk factors associated with seroprevalence and help to identify a target age for the application of a CMV vaccine. PMID:26817022

    Full Text Available Cytomegalovirus (CMV infection is usually asymptomatic in immunocompetent patients. A mononucleosis-like syndrome may develop in some patients. Various organ involvements (eg: encephalitis, meningitis, retinitis, myocarditis, pneumonia, hepatitis, enterocolitis, neuritis, which rarely occur in immunocompetent patients, have also been reported. Cutaneous necrotizing vasculitis caused by CMV infection has been reported very rarely in the literature. Here, a case with a very rare clinical form of CMV infection, presenting with persistent fever and livedo reticularis on the extremities and cutaneous necrotizing vasculitis of the toes, is described, and the relevant literature is reviewed. This case report aims to highlight the possibility of CMV infection to be a cause of cutaneous necrotizing vasculitis.

    Full Text Available Congenital lobar emphysema (CLE is a rare congenital abnormality characterised by overinflation of a pulmonary lobe. Its aetiology is unknown. The management of CLE has traditionally been surgical. A newborn boy with a birthweight of 2.5 kg was delivered at full-term by caesarian section due to food delivery. There was no marked respiratory distress at birth, and little meconium stained liquor was seen on the skin. The initial diagnosis was meconium aspiration syndrome. After computed tomography of the thorax, CLE was diagnosed. The patient was observed throughout for a week and the CT of the thorax was repeated, which revealed that the emphysema had resolved. The nonoperative approach should be considered in asymptomatic patients with CLE.

    Human cytomegalovirus (CMV) represents an important public health concern as it is associated with severe morbidity and mortality in transplant recipients, HIV-infected individuals and pregnant women given the risk of congenital infection. Congenital CMV is a leading cause of neurological sequelae, developmental delay and birth defects worldwide. Cytomegalovirus can be transmitted to the foetus following maternal infection or reactivation. NK cells expressing killer-cell immunoglobulin-like receptors (KIR) are part of the innate immune system and the first line of defence against viral incursions. Previous reports have shown that KIR genes are associated with CMV infections in the post-transplant setting. In this study, we set out to determine whether a protective effect of KIR genes over CMV infection is seen in Mexican pregnant women. Cytomegalovirus infection was assessed through nucleic acid testing in 200 pregnant women and 600 healthy blood donors comprising the Mexican mestizo reference population. Killer-cell immunoglobulin-like receptors and HLA-C genotypes were obtained from 200 pregnant women and 300 reference samples using a comprehensive PCR-SSP approach. We observed statistically lower carrier frequencies of cB03|tA01 gene-content haplotype, of cB03 haplotype motif, of the KIR2DL5 + 2DS3/2DS5 gene pair and of KIR2DL5 amongst CMV-positive pregnant women in comparison with those CMV negative. None of these were associated with CMV status in the reference population. Logistic regression analysis revealed that the most important factor determining CMV status during third-trimester pregnancies was the KIR2DL5 + 2DS3/2DS5 gene pair (OR 0.376 (95%CI 0.174, 0.811, P = 0.013). Our results indicate that CMV-protective KIR gene associations described in Caucasoid populations are also present in the genetically distinct Mexican mestizo population. Our results suggest that certain KIR gene combinations provide protection against CMV infections occurring

    Full Text Available Objective To investigate the imaging and clinicopathological features of pachygyria limited in the right temporo-parieto-occipital lobe and the key points of its diagnosis and treatment, in order to improve the recognition of this disease.  Methods and Results A 2-year-old boy was admitted to hospital because of paroxysmal loss of consciousness and convulsion for 18 months with progressive aggravation. MRI showed malformations of cortical development in the right temporo-parieto-occipital lobe. Epileptic foci resection on the right temporo-parieto-occipital lobe was made. Histological examination after operation showed uneven thickening of gray matter, shrinking of white matter and disappearing cortical stratification, while a lot of dysmorphic neurons, balloon cells and scattered balloon cells in white matter appeared. Immunohistochemical staining revealed that dysmorphic neurons were positive for non-phosphorylated neurofilament protein SMI-32, microtubule-associated protein-2 (MAP-2 and vimentin (Vim or neurofilament protein (NF. Both dysmorphic neurons and balloon cells expressed phosphorylated ribosomal S6 protein (RPS6, while the former was stronger than the latter. Balloon cells were not positive for MAP-2 or Vim. No disturbance of consciousness or limb twitches occurred in this patient during one-year follow-up.  Conclusions Congenital pachygyria was cortical dysplasia caused by the early proliferation and migration disorder of brain, and should be distinguished with focal cortical dysplasia (FCD type Ⅱ b and tuberous sclerosis complex (TSC. Clinical history, imaging and histological features should be included in the diagnosis. DOI: 10.3969/j.issn.1672-6731.2016.02.005

    Transfusion-transmitted cytomegalovirus (TT-CMV) is often asymptomatic, but certain patient populations, such as very low birth weight neonates, fetuses requiring intrauterine transfusion, pregnant women, patients with primary immunodeficiencies, transplant recipients, and patients receiving chemotherapy or transplantation for malignant disease, may be at risk of life-threatening CMV infection. It is unclear whether leukoreduction of cellular blood components is sufficient to reduce TT-CMV or whether CMV serological testing adds additional benefit to leukoreduction. The AABB CMV Prevention Work Group commissioned a systematic review to address these issues and subsequently develop clinical practice guidelines. However, the data were of poor quality, and no studies of significant size have been performed for over a decade. Rather than creating guidelines of questionable utility, the Work Group (with approval of the AABB Board of Directors) voted to prepare this Committee Report. There is wide variation in practices of using leukoreduced components alone or combining CMV-serology and leukoreduction to prevent TT-CMV for at-risk patients. Other approaches may also be feasible to prevent TT-CMV, including plasma nucleic acid testing, pathogen inactivation, and patient blood management programs to reduce the frequency of inappropriate transfusions. It is unlikely that future large-scale clinical trials will be performed to determine whether leukoreduction, CMV-serology, or a combination of both is superior. Consequently, alternative strategies including pragmatic randomized controlled trials, registries, and collaborations for electronic data merging, nontraditional approaches to inform evidence, or development of a systematic approach to inform expert opinion may help to address the issue of CMV-safe blood components.

  19. Crystal Structure of the Human Cytomegalovirus Glycoprotein B.

    2015-10-01

    Full Text Available Human cytomegalovirus (HCMV, a dsDNA, enveloped virus, is a ubiquitous pathogen that establishes lifelong latent infections and caused disease in persons with compromised immune systems, e.g., organ transplant recipients or AIDS patients. HCMV is also a leading cause of congenital viral infections in newborns. Entry of HCMV into cells requires the conserved glycoprotein B (gB, thought to function as a fusogen and reported to bind signaling receptors. gB also elicits a strong immune response in humans and induces the production of neutralizing antibodies although most anti-gB Abs are non-neutralizing. Here, we report the crystal structure of the HCMV gB ectodomain determined to 3.6-Å resolution, which is the first atomic-level structure of any betaherpesvirus glycoprotein. The structure of HCMV gB resembles the postfusion structures of HSV-1 and EBV homologs, establishing it as a new member of the class III viral fusogens. Despite structural similarities, each gB has a unique domain arrangement, demonstrating structural plasticity of gB that may accommodate virus-specific functional requirements. The structure illustrates how extensive glycosylation of the gB ectodomain influences antibody recognition. Antigenic sites that elicit neutralizing antibodies are more heavily glycosylated than those that elicit non-neutralizing antibodies, which suggest that HCMV gB uses glycans to shield neutralizing epitopes while exposing non-neutralizing epitopes. This glycosylation pattern may have evolved to direct the immune response towards generation of non-neutralizing antibodies thus helping HCMV to avoid clearance. HCMV gB structure provides a starting point for elucidation of its antigenic and immunogenic properties and aid in the design of recombinant vaccines and monoclonal antibody therapies.

    A case of pyrexia of unknown origin in a 35-year-old man, who had become a father nine months earlier, is presented. A diagnosis of cytomegalovirus mononucleosis was achieved only after extensive investigations. It is suggested that cytomegalovirus mononucleosis should be added to the differential diagnosis when investigating pyrexia of unknown origin in fathers of young children.

    Congenital cytomegalovirus (CMV) transmission can occur when women acquire CMV while pregnant. Infection control guidelines may reduce risk for transmission. We studied the duration of CMV survival after application of bacteria to the hands and after transfer from the hands to surfaces and the effectiveness of cleansing with water, regular and antibacterial soaps, sanitizer, and diaper wipes. Experiments used CMV AD169 in saliva at initial titers of 1 × 10(5) infectious particles/ml. Samples from hands or surfaces (points between 0 and 15 min) were placed in culture and observed for at least 2 weeks. Samples were also tested using CMV real-time PCR. After application of bacteria to the hands, viable CMV was recovered from 17/20 swabs at 0 min, 18/20 swabs at 1 min, 5/20 swabs at 5 min, and 4/20 swabs at 15 min. After transfer, duration of survival was at least 15 min on plastic (1/2 swabs), 5 min on crackers and glass (3/4 swabs), and 1 min or less on metal and cloth (3/4 swabs); no viable virus was collected from wood, rubber, or hands. After cleansing, no viable virus was recovered using water (0/22), plain soap (0/20), antibacterial soap (0/20), or sanitizer (0/22). Viable CMV was recovered from 4/20 hands 10 min after diaper wipe cleansing. CMV remains viable on hands for sufficient times to allow transmission. CMV may be transferred to surfaces with reduced viability. Hand-cleansing methods were effective at eliminating viable CMV from hands. PMID:24185855

  3. A user's guide to the indirect solid-phase radioimmunoassay for the detection of cytomegalovirus-specific IgM antibodies

    International Nuclear Information System (INIS)

    In this review full laboratory details are given of a solid-phase indirect radioimmunoassay for the detection of specific IgM antibodies against cytomegalovirus. Practical advice is given on readily available commercial sources of reagents, a simple iodination procedure, the rapid dilution of sera under test and calculation of the results with a computer program available from the authors. Problems encountered with the assay are also detailed such as interference by rheumatoid factor, deterioration of the radiolabel and high background binding found with some sera. If these problems are avoided by the methods given in the text then the radioimmunoassay has been shown to give results of 100% specificity with 89% sensitivity for detecting congenital infection and 92% sensitivity for identifying primary cytomegalovirus infection in pregnant women.

    Full Text Available Atrial fibrillation (AF is a common and refractory arrhythmia. Prevalence of AF increases with age. Asymptomatic AF is a state of asymptomatic episodes of arrhythmia and its exact prevalence remains unknown. Ablation and therapy with antiarrhythmic agents may predispose to asymptomatic AF. Detection of silent AF is crucial for prevention of ischaemic stroke. Progress in continuous ECG monitoring by Holter ECG, telemetry methods or implantable devices can provide a useful tools for identifying silent AF. Simple screening procedures like pulse examination and ambulatory ECG may be helpful in arrhythmia detection and logically – ischemic stroke prevention.

  7. Biliary scintigraphy in neonatal cytomegalovirus cholestasis

    International Nuclear Information System (INIS)

    Diagnostic value of hepatobiliary scintigraphy using mebrofenin-Te-99m was assessed in three newborns with cytomegalovirus (CMV) hepatitis and one baby with hepatitis B jaundice. All cases were affected by persistent jaundice with predominately conjugated bilirubin, alcoholic stools, anemia. One of this newborns (case number 1) was suspected of having biliary atresia due to the absence of intestinal excretion of the tracer. After three weeks intestinal passage was seen in scintiscan late after 24 h. Hepatobiliary scintigraphy represents a non-invasive diagnostic procedure which enables the detection of permeability of the biliary tract. (Author)

    Full Text Available Patients with human immunodeficiency virus (HIV infection receiving antiretroviral therapy (ART, despite a reduced viral load and improved immune responses, may experience clinical deterioration. This so called "immune reconstitution inflammatory syndrome (IRIS" is caused by inflammatory response to both intact subclinical pathogens and residual antigens. Cytomegalovirus retinitis is common in HIV-infected patients on ART with a cluster differentiation 4 (CD4+ counts less than 50 cells/mm3. We reported a patient with blurred vision while receiving ART. She had an unmasking classic CMV retinitis after ART.

    Human cytomegalovirus (HCMV) is the most common cause of congenital virus infection. Congenital HCMV infection occurs in 0.2–1% of all births, and causes birth defects and developmental abnormalities, including sensorineural hearing loss and developmental delay. Several key studies have established the guinea pig as a tractable model for the study of congenital HCMV infection and have shown that polyclonal antibodies can be protective [1]–[3]. In this study, we demonstrate that an anti-guinea pig CMV (GPCMV) glycoprotein H/glycoprotein L neutralizing monoclonal antibody protects against fetal infection and loss in the guinea pig. Furthermore, we have delineated the kinetics of GPCMV congenital infection, from maternal infection (salivary glands, seroconversion, placenta) to fetal infection (fetus and amniotic fluid). Our studies support the hypothesis that a neutralizing monoclonal antibody targeting an envelope GPCMV glycoprotein can protect the fetus from infection and may shed light on the therapeutic intervention of HCMV congenital infection in humans.

    2016-07-01

    Classic cerebral toxoplasmosis typically presents with neurologic symptoms such as seizures and mental status changes and histological examination shows focal lesions with necrosis. However, in the diffuse "encephalitic" form, patients are asymptomatic with diffuse, inflammatory, non-necrotic lesions. Asymptomatic diffuse "encephalitic" toxoplasmosis has been reported only in four acquired immunodeficiency syndrome patients and one human immunodeficiency virus (HIV) negative patient with chronic lymphocytic leukemia. We present a 36-year-old HIV-negative woman with systemic lupus erythematosus and lupus nephritis who was on immunosuppression for 9years after cadaveric renal transplant and died from pulmonary hemorrhage and cytomegalovirus pneumonia. Brain autopsy findings revealed multifocal microglial nodules containing Toxoplasma bradyzoites and associated astrogliosis. These nodules were prominent in the cerebellum, midbrain and medulla and also present in the cortex and thalamus. No coagulative necrosis, necrotizing abscesses, or other opportunistic infections were present. The patient had previously exhibited no neurologic symptoms and there was no clinical suspicion for toxoplasmosis. To the best of our knowledge, this is the first case of diffuse, non-necrotizing, "encephalitic" cerebral toxoplasmosis reported in a lupus patient and also the first reported female case.

    Summary: In order to investigate the human cytomegalovirus (HCMV) infection, the mouse cytomegalovirus (MCMV) infected mice were experimentally studied. 6 to 8 week old female BALB/C mice with immunosuppression were selected to undergo the MCMV inoculations: intracranial inoculation and peritoneal inoculation. MCMV of the infected mice in various organs and tissues were detected by using β-gal staining and in situ nucleic acid hybridization assay. The pathological changes were observed in HE staining paraffin-embedded sections. It was found that all the MCMV infected mice showed the retardation of growth and development, and feather looseness. Both intracranial inoculation of 104 PFU viruses or peritoneal inoculation of 106 PFU viruses resulted in the pathological changes, to some extent, of various organs and tissues in the mice. The pathological changes in liver were consistent with the amount of β-gal staining positive cells, indicating the liver lesions were mainly caused by viral proliferation. It was also found that the viruses in the immunosuppressed mice subjected to intracranial inoculation could spread to whole body organs, while the viruses in the immunosuppressed mice subjected to intrapeitoneal inoculation couldn't spread to the brain, suggesting blood-brain barrier could prevent the virus from spreading to the brain.

    2016-01-01

    The prevalence of cytomegalovirus in the burn population is high. However, its role in the clinical management of burn patients is still being defined. This report documents a 41-year-old man who developed cytomegalovirus (CMV) colitis after being admitted with a 72% burn. Before the administration of ganciclovir, the authors had difficulty controlling his quantitative wound cultures with serial debridements, topical agents, and systemic antibiotics for known pathogens, which led to graft loss. After the ganciclovir was given, his quantitative wound cultures improved without changing the authors' topical agents or systemic antibiotics and had improved graft take. Whether CMV infection alone contributed to an increased morbidity in this patient or the combination of bacteria/fungal infection with CMV led to a synergistic effect is still not clearly understood. CMV may have contributed to a dysfunction in his cell mediated immunity, which, in turn, lowered the bacterial and fungal load necessary to cause graft loss. Patients who continue to do poorly despite adequate treatment for known pathogens may need to be screened for CMV and treated. PMID:26056763

    Full Text Available Introduction: Menetrier´s disease is rare in pediatrics. With no established etiology has been associated with viral and bacterial infections most of them able to generate an inflammatory process and protein-loosing with clinical abdominal pain, nausea, vomiting and edema, spontaneous resolution after 4-6 weeks without sequelae. The main objective is to describe a menetrier´s disease case in a male child in pediatric. Clinical case: a three years old male child without perinatal history, with clinical profile of five days with vomiting, abundant diarrhea, not dysentery, and fever, in the last two days with bipalpebral edema. After the cropology test the patient presented Giardia lamblia cysts, treated with metronidazole. The child is remitted to Hospital Infantil Napoleón Franco Pareja in Cartagena-Colombia, because of evidence of edema bipalpebral. In the emergency room male child presented good general condition with acute illness, stable vital signs, blood count with mild leukocytosis, blood smear with toxic granulations in neutrophils, partial urine without proteinuria, serum albumin 1.26 g../ dl. normal transaminases, normal serum electrolytes, normal lipid profile, ultrasound with distended bowel moderate, upper endoscopy with hypertrophy folds mucosa and gastric body, hyperemia and friability without erosions. The biopsy showed chronic active gastropathy with marked foveal hyperplasia compatible with Menetrier disease. During his hospitalization was administered albumin 1 g / kg for four days with resolution of edema and serum protein, the patient was discharged with normal albumin and subsequent controls and then he continued asymptomatic with complete resolution of the clinical disease. Conclusion: Menetrier´s disease in children is self-limiting with duration from 4 to 6 weeks; it can present abdominal pain, vomiting, nausea and edema. With the clinical and endoscopic findings of gastric folds hypertrophy can be presumed diagnosis

    Full Text Available Aim: Pediatric lung resection is a relatively uncommon procedure that is usually performed for congenital lesions. In recent years, thoracoscopic resection has become increasingly popular, particularly for small peripheral lesions. The aim of this study was to review our experience with traditional open lung resection in order to evaluate the existing "gold standard." Materials and Methods: We carried out a retrospective analysis of all children having lung resection for congenital lesions at our institution between 1997 and 2004. Data were collected from analysis of case notes, operative records and clinical consultation. The mean follow-up was 37.95 months. The data were analyzed using SPSS. Results: Forty-one children (13 F/28 M underwent major lung resections during the study period. Their median age was 4.66 months (1 day-9 years. The resected lesions included 21 congenital cystic adenomatoid malformations, 14 congenital lobar emphysema, four sequestrations and one bronchogenic cyst. Fifty percent of the lesions were diagnosed antenatally. Twenty-six patients had a complete lobectomy while 15 patients had parenchymal sparing resection of the lesion alone. Mean postoperative stay was 5.7 days. There have been no complications in any of the patients. All patients are currently alive, asymptomatic and well. None of the patients have any significant chest deformity. Conclusions: We conclude that open lung resection enables parenchymal sparing surgery, is versatile, has few complications and produces very good long-term results. It remains the "gold standard" against which minimally invasive techniques may be judged.

    Full Text Available Background: Perinatal viral infections of fetus are among the leading causes of congenital cataract and identifying the viral etiology is important. Objectives: To detect the presence of Rubella virus (RV, herpes simplex virus (HSV and cytomegalovirus (CMV in lens aspirate specimens obtained from patients with congenital cataract and relate the results with serology. Setting and Design: Prospective study carried out in tertiary care hospital. Materials and Methods: Fifty lens aspirates from 50 infants with congenital cataract were subjected to HSV, RV isolation and polymerase chain reaction (PCR for detection of HSV and CMV. Reverse transcription polymerase chain reaction (RT-PCR was applied for RV detection. Peripheral blood specimens were screened for anti-HSV, RV and CMV antibodies by enzyme-linked immunosorbant assay (ELISA. Results: Rubella virus was detected in nine (18% lens aspirates, by nRT-PCR which includes six positive by culture. HSV-2 DNA was detected in nine other lens aspirates, while CMV was not detected by PCR. Serological results did not correlate with the presence of viruses in the lens aspirates. This is the first report of detection of HSV-2 DNA in cases of congenital cataract. Conclusions: Cytomegalovirus may not be playing a significant role in causation of congenital cataract. The role of serology in identifying causative viral infection for congenital cataract needs to be re-evaluated.

    Objective To investigate the polymorphism of human cytomegalovirus (HCMV) UL150 open reading frame(ORF) in low-passaged clinical isolates, and to study the relationship between the polymorphism and different pathogenesis of congenital HCMV infection.Methods PCR was performed to amplify the entire HCMV UL150 ORF region of 29 clinical isolates, which hadbeen proven containing detectable HCMV-DNA using fluorescence quantitative PCR. PCR amplifcation products weresequenced directly, and the data were analyzed.Results Totally 25 among 29 isolates were amplified, and 18 isolates were sequenced successfully. HCMVUL150 ORF sequences derived from congenitally infected infants were high variability. The UL150 ORF in all 18 clinical isolates shifted backward by 8 nucleotides leading to frame-shift, and contained a single nucleotide deletion at nucleotide position 226 compared with that of Toledo strain. The nucleotide diversity was 0. 1% to 6. 8% and the amino acid diversity was 0. 2% to 19. 2% related to Toledo strain. However, the nucleotide diversity was 0. 1% to 6.4% and amino acid diversity was 0. 2% to 8.3% by compared with Merlin strain. Compared with Toledo, 4 new cysteine residues and 13 additional posttranslational modification sites were observed in UL150 putative proteins of clinical isolates. Moreover, the UL150 putative protein contained an additional transmembrane helix at position of 4-17 amino acid related to Toledo.Conclusion HCMV UL150 ORF and deduced amino acid sequences of clinical strains are hypervariability. No obvious linkage between the polymorphism and different pathogenesis of congenital HCMV infection is found.

    Background: Langerhans cell histiocytosis is a rare proliferative histiocytic disease of unknown etiology. Histologically, it is characterized by granuloma-like proliferation of Langerhans-type dendritic cells derived from bone marrow. Many investigators have suggested the possible role of viruses such as Epstein-Barr virus, human herpesvirus-6 (HHV-6), herpes simplex virus (HSV) types 1 and 2, and Cytomegalovirus in the pathogenesis of Langerhans cell histiocytosis. Objectives: In this study, we have investigated the presence of Cytomegalovirus in Langerhans cell histiocytosis in Iranian children. Patients and Methods: In this retrospective study, we have investigated the presence of Cytomegalovirus DNA expression, using paraffin-embedded tissue samples of 30 patients with Langerhans cell histiocytosis and 30 age and site-matched controls by qualitative Polymerase Chain Reaction (PCR) method. Results: No significant difference in prevalence of Cytomegalovirus presence between patients and controls was found. Cytomegalovirus was found by qualitative PCR in only 2 (6.66%) out of 30 patients and in 1 (3.3%) of 30 control samples with a P value of 1 (1.00 > 0.05) using chi-square test with OR: 2.07; 95% CI of OR: 0.18 - 24.15. Conclusions: Our findings do not support the hypothesis of a possible role for Cytomegalovirus in the pathogenesis of Langerhans cell histiocytosis. PMID:27307972

  11. Asymptomatic cerebral hemorrhage detected by MRI

    International Nuclear Information System (INIS)

    Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule.

    Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule. The secondary asymptomatic hemorrhage were due to AVM and angiomas in the frontal cortex, thalamus and pons. (author).

    A 60-year-old woman with rheumatoid arthritis treated with methotrexate for a decade complained of slight epigastric discomfort. A positive cytomegalovirus (CMV) antigenemia test indicated the probability of CMV-related gastrointestinal infection, for which esophagogastroduodenoscopy was performed. Endoscopic findings showed a non-specific duodenal mucosal lesion;however, pathological investigation revealed evidence of CMV duodenitis. There is scarce information on the clinical and pathological features of CMV-related duodenitis, likely due to its low prevalence. CMV infection in the upper gastrointestinal tract should be considered as a differential diagnosis in high-risk individuals, particularly those with symptoms relating to the digestive system. Biopsy examinations are preferable for the definitive diagnosis of CMV gastrointestinal infection, even without specific endoscopic features. PMID:26490030

    Congenital myasthenia gravis is caused by genetic mutations affecting neuromuscular transmission, characterized by muscle weakness usually starting in childhood. A two and a half years old male child presented with bilateral ptosis and hoarseness of voice. The symptoms progressed giving the clinical impression of congenital myasthenia gravis. A series of tests were done including Ice Pack Test, acetylcholine receptor antibody test, trial of steroids and finally neostigmine test which confirmed the diagnosis. This case illustrates the challenges in diagnosing congenital myasthenia gravis and highlights the potential benefits of neostigmine test in its diagnosis. PMID:23823963

    Full Text Available "nPregnant women are at increased risk for urinary tract infection (UTI but in many cases infection is asymptomatic. This study was performed to determine the incidence of asymptomatic bacteriuria and pyuria in pregnant women. A total of 86 pregnant women during first trimester and 56 nonpregnant women were evaluated. All subjects were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine samples were collected for both groups. Urine samples were examined microscopically and were cultured. Bacteriological examination revealed asymptomatic bacteriuria in 25 (29.1% and 3 (5.4% of the study group and controls, respectively (P < 0.05. Microscopic analysis of urine revealed pyuria in 18 (20.9% and 3 (5.4% of the study group and controls, respectively (P < 0.05. In study group, Escherichia coli were found in 20%, Staphylococcus epidermidis in 36%, Staphylococcus haemolyticus in 12%, streptococcus group D in 12%, Staphylococcus saprophyticus in 12% and Proteus mirabilis in 8%. In control group, E. coli were found in 33.3% and S. epidermidis in 66.7%. Our results show that the incidence of asymptomatic bacteriuria is significantly higher in pregnant women than nonpregnant women. The main finding in the present study was that 29.1% of the pregnant women who were in first trimester had asymptomatic bacteriuria which is much higher than figures reported from other countries. The use of microscopic urinanalysis was not an effective method of detecting asymptomatic bacteriuria and urine culture is necessary for screening these pregnant women.

    2015-01-01

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    Full Text Available We present a case of mature congenital orbital teratoma managed with lid-sparing exenteration and dermis fat graft. This is a case report on the management of congenital orbital teratoma. A full-term baby was born in Fiji with prolapsed right globe which was surrounded by a nonpulsatile, cystic mass. Clinical and imaging features were consistent with congenital orbital teratoma. Due to limited surgical expertise, the patient was transferred to Adelaide, Australia for further management. The patient underwent a lid-sparing exenteration with frozen section control of the apical margin. A dermis fat graft from the groin was placed beneath the lid skin to provide volume. Histopathology revealed mature tissues from each of the three germ cell layers which confirmed the diagnosis of mature teratoma. We describe the successful use of demis fat graft in socket reconstruction following lid-sparing exenteration for congenital orbital teratoma.

    2014-09-01

    Congenital scoliosis due to vertebral anomalies may occur in less than 0.1% of the population. Several different theories have been put forth in the literature to account for the etiology of congenital scoliosis and the vertebral anomalies which contribute to its development. The study of scoliosis in twins has contributed to the understanding of causative factors including genetics, environment and in utero events during embryologic development. Case reports of fraternal (non-identical) juvenile male twins with congenital scoliosis associated with differing congenital vertebral anomalies are presented. Both children were asymptomatic at the time of the initial consultation and showed no signs of neurologic compromise. Rapidly progressive, severe genetic scoliosis requires prudent observation and referral to a pediatric orthopedic surgeon to determine appropriate options for care and to screen for potentially life threatening disorders. Chiropractors may be seen as gatekeepers for scoliosis and a thorough understanding of appropriate standards of care is required. PMID:25202158

    2014-02-01

    Full Text Available Development of a vaccine against congenital infection with human cytomegalovirus (HCMV is a major public health priority. A potential vaccine target receiving considerable recent attention is the pentameric complex (PC of HCMV proteins consisting of gL, gH, UL128, UL130, and UL131, since some antibodies against these target proteins are capable of potently neutralizing virus at epithelial and endothelial cell surfaces. Recently, homologous proteins have been described for guinea pig cytomegalovirus (GPCMV, consisting of gH, gL, and the GPCMV proteins GP129, GP131, and GP133. To investigate these proteins as potential vaccine targets, expression of GP129-GP133 transcripts was confirmed by reverse-transcriptase PCR. Mass spectrometry combined with western blot assays demonstrated the presence of GP129, GP131, and GP133 proteins in virus particles. Recombinant proteins corresponding to these PC proteins were generated in baculovirus, and as GST fusion proteins. Recombinant proteins were noted to be immunoreactive with convalescent sera from infected animals, suggesting that these proteins are recognized in the humoral immune response to GPCMV infection. These analyses support the study of PC-based recombinant vaccines in the GPCMV congenital infection model.

    Congenital pseudarthrosis of the clavicle is a rare condition present at birth but often diagnosed later in childhood. Indications for surgical treatment include pain, deformity or neurovascular compromise. Reconstruction usually involves resection of the pseudarthrosis, placement of iliac crest bone graft or graft substitute and internal fixation. In this paper, we present a case of congenital pseudarthrosis of the clavicle in a 9-year-old boy who was treated with plate fixation and bone autograft. The majority of patients who undergo surgery because of cosmetic or functional problem heal well and proceed with a normal, unrestricted life. However, for those patients who are not bothered by the cosmetic appearance of the pseudarthrosis and are asymptomatic in that they are not functionally limited, non-surgical treatment is a viable option.

The development of congenital syphilis is mainly ascribed to the lack of prenatal serologic testing and proper management of syphilis in pregnant women. Congenital syphilis is different from acquired syphilis in many aspects, such as clinical manifestations, diagnosis and management. Most cases of congenital syphilis are asymptomatic at birth, and to diagnose congenital syphilis only based on the results of rapid plasma reagin (RPR) test and T. pallidum particle agglutination (TPPA) assay often leads to missed diagnosis and misdiagnosis of syphilis in asymptomatic babies. Thereby, clinicians should be particularly vigilant for the possibility of asymptomatic congenital syphilis.

    Human cytomegalovirus (HCMV) is a ubiquitous virus.Although the infection in healthy children and adults is usually asymptomatic,in immunocompromised individuals and newborns it is a significant cause of morbidity and mortality.UL49,an essential gene of HCMV,is highly conserved among various HCMV strains.The expression of UL49 is correlated with the production of virions.When UL49 is inhibited in the HCMV,the production of virions is reduced severely.In this study,RNA interference was applied to further investigate the roles of UL49 in viral replication.Two effective small interfering RNAs against UL49 were selected.Silencing of UL49 in HCMV-infected human foreskin fibroblast cells reduced the transcription levels of early and late genes,but not immediate-early ones.In addition,the viral DNA content was significantly reduced.This is the first time to uncover the role of UL49 in viral DNA synthesis,which indicates that UL49 might play an important role in this period.So the down-regulation of UL49 mRNA using RNAi might be a potential clinical therapy against the virus.

  7. Human cytomegalovirus infection dysregulates the canonical Wnt/β-catenin signaling pathway.

    Directory of Open Access Journals (Sweden)

    Magdalena Angelova

    Full Text Available Human Cytomegalovirus (HCMV is a ubiquitous herpesvirus that currently infects a large percentage of the world population. Although usually asymptomatic in healthy individuals, HCMV infection during pregnancy may cause spontaneous abortions, premature delivery, or permanent neurological disabilities in infants infected in utero. During infection, the virus exerts control over a multitude of host signaling pathways. Wnt/β-catenin signaling, an essential pathway involved in cell cycle control, differentiation, embryonic development, placentation and metastasis, is frequently dysregulated by viruses. How HCMV infection affects this critical pathway is not currently known. In this study, we demonstrate that HCMV dysregulates Wnt/β-catenin signaling in dermal fibroblasts and human placental extravillous trophoblasts. Infection inhibits Wnt-induced transcriptional activity of β-catenin and expression of β-catenin target genes in these cells. HCMV infection leads to β-catenin protein accumulation in a discrete juxtanuclear region. Levels of β-catenin in membrane-associated and cytosolic pools, as well as nuclear β-catenin, are reduced after infection; while transcription of the β-catenin gene is unchanged, suggesting enhanced degradation. Given the critical role of Wnt/β-catenin signaling in cellular processes, these findings represent a novel and important mechanism whereby HCMV disrupts normal cellular function.

    Full Text Available Background - Neonatal cholestasis syndrome with an intra or extrahepatic origin has been associated to viral infections. The participation of the cytomegalovirus in the etiopathogenesis of neonatal hepatitis has been already known for some time, but only recently there have been indications that this virus may be one of the possible etiological factors for extrahepatic biliary atresia. Aims - To assess the prevalence of infection by cytomegalovirus in patients with intrahepatic cholestasis and extrahepatic cholestasis. To compare the clinical characteristics of the intrahepatic cholestasis and extrahepatic cholestasis groups with the cytomegalovirus serological results. Patients and Methods - This study consisted of 76 patients with neonatal cholestasis who were admitted between January 1980 and January 1999 when they underwent a cytomegalovirus serologic study using the ELISA method. A case note was kept on each patient with the following data: age of patient at admission, serologic result for cytomegalovirus, history of maternal infection, prematurity, fetal distress, birth weight, ponderal gain, choluria and fecal acholia. The final anatomic diagnosis of cholestasis was based on the results of an abdominal ultrasonography, a liver biopsy and its evolution. The patients were then divided into two groups: group I - intrahepatic cholestasis and group II - extrahepatic cholestasis. Each of these groups were then divided into two subgroups: subgroup A - positive serology (IgM for cytomegalovirus and subgroup B - negative serology (IgM for cytomegalovirus. Results - The frequency of positive serology (IgM for cytomegalovirus was 29.4% in children with intrahepatic cholestasis and 28.5% in children with extrahepatic cholestasis. In comparison with group IIB, group IIA presented a higher rate of maternal infection history. The patients in group IIA demonstrated a delayed access to the service in comparison with group IA. The groups did not

    One of the more polarized ongoing debates in the brain tumor field over recent years has centered on the association of cytomegalovirus (CMV) with glioblastoma. Several laboratories have reported the presence of CMV antigens in glioblastoma patient specimens, whereas others have failed to detect them. CMV genomic DNA and mRNAs have been detected by PCR, but not in next-generation sequencing studies. CMV promotes high grade glioma progression in a mouse genetic model, and many CMV proteins promote cancer hallmarks in vitro, but actively replicating virus has not been isolated from tumor samples. A consensus is gradually emerging in which the presence of CMV antigens in glioblastoma is increasingly accepted. However, it remains challenging to understand this mechanistically due to the low levels of CMV nucleic acids and the absence of viral replication observed in tumors thus far. Nonetheless, these observations have inspired the development of novel therapeutic approaches based on anti-viral drugs and immunotherapy. The potential benefit of valganciclovir in glioblastoma has generated great interest, but efficacy remains to be established in a randomized trial. Also, early stage immunotherapy trials targeting CMV have shown promise. In the near future we will know more answers to these questions, and although areas of controversy may remain, and the mechanisms and roles of CMV in tumor growth are yet to be clearly defined, this widespread virus may have created important new therapeutic concepts and opportunities for the treatment of glioblastoma.

  11. Immunomodulation by cytomegaloviruses: manipulative strategies beyond evasion.

    Human cytomegalovirus (CMV) remains the major infectious cause of birth defects as well as an important opportunistic pathogen. Individuals infected with CMV mount a strong immune response that suppresses persistent viral replication and maintains life-long latency. Loss of immune control opens the way to virus reactivation and disease. The large number of immunomodulatory functions encoded by CMV increases the efficiency of infection, dissemination, reactivation and persistent infection in hosts with intact immune systems and could contribute to virulence in immunocompromised hosts. These functions modulate both the innate and adaptive arms of the immune response and appear to target cellular rather than humoral responses preferentially. CMV encodes a diverse arsenal of proteins focused on altering and/or mimicking: (1) classical and non-classical major histocompatibility complex (MHC) protein function; (2) leukocyte migration, activation and cytokine responses; and (3) host cell susceptibility to apoptosis. Evidence that the host evolves mechanisms to counteract virus immune modulation is also accumulating. Although immune evasion is certainly one clear goal of the virus, the pro-inflammatory impact of certain viral functions suggests that increased inflammation benefits viral dissemination. The ability of such viral functions to successfully 'face off' against the host immune system ensures the success of this pathogen in the human population and could provide key insights into disease mechanisms.

  12. Cytomegalovirus pneumonia in immunocompromised patients : HRCT findings

    International Nuclear Information System (INIS)

    The purpose of this study was to describe the HRCT findings of cytomegalovirus (CMV) pneumonia in immunocompromised patients. Eleven immunocompromised patients with proven CMV pneumonia underwent HRCT scanning. Three had undergone a transplant, three had a malignant tumor, two had undergone steroid therapy, one had pancytopenia and two had AIDS. In all patients, CMV was diagnosed by bronchoalveolar lavage culture. HRCT scans were retrospectively reviewed by two radiologists for disease distribution and patterns. HRCT findings included ground-glass opacity(n=11), consolidation (n=7), reticular opacity (n=10), multiple small nodules or mass (n=6), and bronchiectasis or bronchial wall thickening (n=5). Ground-glass opacity was usually distributed bilaterally and diffusely. Consolidation was most marked in the lower lobes, and reticular opacity and nodules or mass showed a variable, nonsegmental distribution. The HRCT findings of CMV pneumonia in immunocompromised patients were variable and nonspecific. The most common patterns included diffuse ground-glass opacity and consolidation, combined with variable reticulation

    Full Text Available We report the occurrence of congenital toxoplasmosis in three infants born to HIV infected women who had high anti-toxoplasma IgG and negative IgM during pregnancy. We briefly reviewed available literature and discussed the possible transmission mechanisms of congenital toxoplasmosis among HIV infected pregnant women. Serum samples were tested for Toxoplasma gondii IgM and IgG antibodies using commercial enzyme immunoassay and IgG-avidity tests. In the first case, fetal death occurred at 28th week of gestation. In the second case, congenital toxoplasmosis was diagnosis at 6th month of life; and in the third case, an HIV-infected newborn, congenital toxoplasmosis was asymptomatic. These cases point out to the possibility of enhanced maternal-fetal transmission of T. gondii infection by HIV-infected women chronically infected, which may have important public health consequences, considering that increasing frequency of HIV-infection has been observed among women of childbearing age around the world.

    Full Text Available Congenital cataract is a leading cause of visual deprivation which can damage the developing visual system of a child; therefore early diagnosis, management and long-term follow-up are essential. It is recommended that all neonates be screened by red reflex examination at birth and suspected cases be referred to ophthalmic centers. Early surgery (1 year is highly recommended. After surgery, amblyopia treatment and periodic follow-up examinations should be started as soon as possible to achieve a satisfactory visual outcome. Practitioners should consider the possibility of posterior capsular opacity, elevated intraocular pressure and amblyopia during follow-up, especially in eyes with microphthalmia and/or associated congenital anomalies. All strabismic children should undergo slit lamp examination prior to strabismus surgery to rule out congenital lens opacities. From a social point of view, equal and fair medical care should be provided to all children regardless of gender.

    Congenital midline nasal masses are uncommon anomalies including nasal dermoids/epidermoids, nasal glial heterotopias and encephaloceles. These lesions can occur at the nasal bridge, extend intranasally and have intracranial extension with communication to the subarachnoid space. Therefore, accurate diagnosis of these lesions is critically important for presurgical planning and prevention of potentially fatal complications. Neuroimaging is essential in the evaluation of congenital midline nasal masses to identify the specific type of lesion, evaluate for the presence of intracranial extension and allow for appropriate presurgical planning.

  19. Congenital spinal malformations

    International Nuclear Information System (INIS)

    Congenital spinal malformations form a complex and heterogeneous group of disorders whose pathogenesis is best explained embryologically. Radiologically, it is important to formulate a diagnosis when the disorder first becomes symptomatic. However, it is also crucial to detect complications of the disorder or of the respective therapeutic interventions in the further course of the disease such as hydromyelia or re-tethering after repair of a meningomyelocele. Moreover, once a congenital spinal malformation is diagnosed, associated malformations should be sought after. A possible syndromal classification such as in OEIS- or VACTERL-syndromes should also be considered. (orig.)

    Full Text Available Congenital cyst of the pancreas is an uncommon problem in the pediatric patient. The common symptoms at the time of diagnosis have been abdominal mass and pain or fullness, nausea and vomiting. Despite of various paraclinic methods for diagnosis, ultrasound is now recognized as the most effective and best noninvasive method for diagnosis of pancreatic cyts. Surgical intervention is the best mode of therapy. Upper abdominal cystic mass are seen in the fetus and newborn infants. In Amirkabir Hospital, during 12 years from 1981 to 1993, 8 pancreatic cysts have been operated on and only in this case it was congenital.

    Full Text Available Abstract Background CMV-induced vasculopathy and thrombosis have been reported, but they are rare conditions usually encountered in immunocompromised patients. However more and more complications of CMV infections are recognized in immunocompetent patients. Case presentation We present a case report of a previously healthy adult with cytomegalovirus infection that was complicated by tibiopopliteal deep venous thrombosis and in whom Factor V Leiden heterozygous mutation was found. Conclusion This new case report emphasizes the involvement of cytomegalovirus in induction of vascular thrombosis in patients with predisposing risk factors for thrombosis. It is necessary to screen for CMV infection in patients with spontaneous thrombosis and an history of fever.

    We studied 53 newborn babies with congenital syphilis. The common clinical features seen were low birth weight, hepatosplenomegaly, anaemia, jaundice, and symmetrical superficial desquamation of the skin affecting palms and soles. The presence of these clinical signs is highly suggestive of early congenital syphilis. Hydrops fetalis without rhesus or ABO isoimmunisation should always arouse the suspicion of congenital syphilis.

  6. Treatment approaches to asymptomatic follicular lymphoma.

    2013-12-01

    Follicular lymphoma is a heterogeneous disease in which some patients present an indolent evolution for decades and others, a rather aggressive form of the disease requiring immediate therapy. While immunochemotherapy has emerged as a standard of care for symptomatic patients, treatment of the asymptomatic population remains controversial. Since the disease is still considered incurable, delayed initiation of therapy is an acceptable option. However, four single injections of rituximab can result in an acceptable clinical response and can improve the duration of the interval without cytotoxic therapy. With recent therapeutic approaches that enable substantial improvements in life expectancy for follicular lymphoma patients, limiting short- or long-term treatment toxicities appears as a new concern in the asymptomatic population. Based on these options, the challenge is to preserve patient quality of life and prolong survival: from the patient's perspective, his/her opinion is therefore of significant importance.

  7. Cerebral blood flow in asymptomatic individuals

    International Nuclear Information System (INIS)

    We studied the relationship between cortical grey matter flow (CBF) and age, cerebrovascular risk factors and the severity of subcortical hypersignals (HS, hyperintensity score in MRI) in 47 asymptomatic subjects with cerebrovascular risk factors. Multiple regression analysis revealed that HS was most strongly related to CBF, and that hematocrit, age and evidence of ischemic change detected in the electrocardiogram also appeared to be independent determinants of CBF. Both the severity and location of hypersignals were correlated with CBF. The most significant negative correlation observed was that between CBF and HS in the basal ganglia-thalamic region, where the degree of signal abnormality was modest. Decreased CBF in asymptomatic subjects with cerebrovascular risk factors may be related to microcirculatory disturbance associated with elevated hematocrit and an increase in the number of risk factors, and functional suppression of cerebral cortex due to the neuronal disconnection associated with subcortical lesions. In addition, impaired cerebral circulation may be related to MRI signal abnormalities. (author)

    Background Human cytomegalovirus (HCMV) infects a number of organs and tissues in vivo. The different symptoms and tissue tropisms of HCMV infection perhaps result from genetic polymorphism. A new region of DNA containing at least 19 open reading frames(ORFs) (denoted UL133 to 151) was found in the low-passage HCMV clinical strain, Toledo, and several other low-passage clinical isolates, but not present in the HCMV laboratory strain, AD169. One of these genes, UL143, was studied to explore the sequence variability of UL143 ORF in HCMV clinical isolates and examine the possible association between gene variability and the outcome of HCMV infection.Methods The UL143 gene of the strains obtained from suspected congenitally HCMV-infected infants was amplified by polymerase chain reaction (PCR) and sequenced.Results Nineteen sequences of the strains were divided into 2 major groups, G1(n=16) and G2(n=3). All of the sequences had frame-shift mutation compared to Toledo. Nucleotide polymorphisms conferred substantial amino acid substitutions when compared with Toledo. All 16 UL143 putative proteins of the strains in G1 had a new myristylation site and loss of two PKC sites owing to missense mutations. No convincing relationships were observed between the presence of HCMV disease and the UL 143 sequence group.Conclusions HCMV-UL143 existed in low passage isolates. Sequence variability caused by frame-shift mutation was found in all HCMV clinical strains. No obvious linkage was observed between UL143 polymorphisms and the outcome of suspected congenital HCMV infection.

    The incidence of congenital cytomegalovirus (CMV) disease is dependent on the rate of virus acquisition by susceptible women in temporal proximity to pregnancy. Information about serostatus may help to identify high-risk groups and target interventions. Each year from 1991 to 2000, cord blood specimens (surrogates for maternal serum) from 100 consecutive deliveries were obtained at three hospitals. The presence of CMV immunoglobulin G antibody was correlated with demographic data. Overall, 58% of 2992 women were seropositive. After stratification by socioeconomic status (SES), nonwhite race was strongly associated with seropositivity (odds ratio, 3.0; 95% confidence interval [CI], 2.5 to 3.8), and after stratification by race, lower SES also was associated (odds ratio, 2.0; 95% CI, 1.7 to 2.3). There were no trends in seroprevalence over time in any demographic group. However, among white women 21 to 29 years of age, a significant association was found with later birth cohort. Seropositivity ranged from 40% among older, white primigravidas of upper SES to 89% among older, nonwhite, multigravid women of lower SES. These data suggest high rates of CMV transmission among nonwhite women of lower SES. Because these women tended to deliver infants at younger ages, delaying pregnancy even a few years might reduce the incidence of congenital disease. In contrast, most white, upper SES women remain susceptible to primary infection during their childbearing years. Such women born after 1975 may be more likely to reach the childbearing years with CMV immunity as compared with women born before then. PMID:16215924

    The prognostic significance of asymptomatic bacteriuria resides in the observation that the prevalence is, relatively, high in persons with certain medical conditions, such as diabetes mellitus and pregnancy. This prevalence might, even, be higher in patients with human immunodeficiency virus infection. Hence, this study set out to determine the prevalence of asymptomatic bacteriuria among symptom free and newly enrolled HIV infected pregnant women attending PMTCT unit of Antiretroviral Clinic of University College Hospital, Ibadan, Nigeria between 1st May and 30th September 2007.Information was obtained on the socio-demographic characteristics of the subjects, CD4 count and viral load. Microbial culture was carried out on aseptically collected urines from the patients. Statistical analysis was done with SPSS 12 package. There were 161 analyzable samples from the participants. The mean age and gestational age at presentation of participants was 30.49 ± 4.3 years and 27.3 ± 3.2 weeks, respectively with modal parity of 2. Twenty-five (15.5%) of the urine samples significantly grew bacteria. The CD4 cells were significantly lower and the viral loads significantly higher(250.52 vs. 355.57 cells/mm3; 88,731 vs. 55,384 copies/ml; p = asymptomatic bacteriuria among PLWHAs is high. The microbial isolate from the urine samples were not different from those of HIV-negative patients. PMID:21178431

    Leonardo D'Aiuto

    Full Text Available Human cytomegalovirus (HCMV infection is one of the leading prenatal causes of congenital mental retardation and deformities world-wide. Access to cultured human neuronal lineages, necessary to understand the species specific pathogenic effects of HCMV, has been limited by difficulties in sustaining primary human neuronal cultures. Human induced pluripotent stem (iPS cells now provide an opportunity for such research. We derived iPS cells from human adult fibroblasts and induced neural lineages to investigate their susceptibility to infection with HCMV strain Ad169. Analysis of iPS cells, iPS-derived neural stem cells (NSCs, neural progenitor cells (NPCs and neurons suggests that (i iPS cells are not permissive to HCMV infection, i.e., they do not permit a full viral replication cycle; (ii Neural stem cells have impaired differentiation when infected by HCMV; (iii NPCs are fully permissive for HCMV infection; altered expression of genes related to neural metabolism or neuronal differentiation is also observed; (iv most iPS-derived neurons are not permissive to HCMV infection; and (v infected neurons have impaired calcium influx in response to glutamate.

    2007-09-01

    Human cytomegalovirus (HCMV), a ubiquitous human pathogen, is the leading cause of birth defects in newborns. A region (referred to as UL/b′) present in the Toledo strain of HCMV and low-passage clinical isolates) contains 22 additional genes, which are absent in the highly passaged laboratory strain AD169. One of these genes, UL145 open reading frame (ORF), is located between the highly variable genes UL144 and UL146. To assess the structure of the UL145 gene, the UL145 ORF was amplified by PCR and sequenced from 16 low-passage clinical isolates and 15 non-passage strains from suspected congenitally infected infants. Nine UL145 sequences previously published in the GenBank were used for sequence comparison. The identities of the gene and the similarities of its putative protein among all strains were 95.9–100% and 96.6–100%, respectively. The post-translational modification motifs of the UL145 putative protein in clinical strains were conserved, comprising the protein kinase C phosphorylation motif (PKC) and casein kinase II phosphorylation site (CK-II). We conclude that the structure of the UL145 gene and its putative protein are relatively conserved among clinical strains, irrespective of whether the strains come from patients with different manifestations, from different areas of the world, or were passaged or not in human embryonic lung fibroblast (HELF) cells.

    Infection with human cytomegalovirus (CMV) during pregnancy is the most common cause of congenital disorders, and can lead to severe life-long disabilities with associated high cost of care. Since there is no vaccine or effective treatment, current efforts are focused on identifying potent neutralizing antibodies. A panel of CMV monoclonal antibodies identified from patent applications, was synthesized and expressed in order to reproduce data from the literature showing that anti-glycoprotein B antibodies neutralized virus entry into all cell types and that anti-pentameric complex antibodies are highly potent in preventing virus entry into epithelial cells. It had not been established whether antibodies could prevent subsequent rounds of infection that are mediated primarily by direct cell-to-cell transmission. A thorough validation of a plaque reduction assay to monitor cell-to-cell spread led to the conclusion that neutralizing antibodies do not significantly inhibit plaque formation or reduce plaque size when they are added post-infection.

    Objective To explore the relationship between human cytomegalovirus (HCMV) UL144 sequence variability and clinical disease.Methods HCMV UL144 open reading frame (ORF) was amplified by PCR assay in 72 lowpassage isolates [65 congenitally infective children and 7 healthy children who were HCMV-DNA positive by quantitative PCR (qPCR)]. All positive PCR products were analyzed by heteroduplex mobility assay and single-stranded conformation polymorphism (HMA-SSCP) and 32 of them were sequenced.Resuits Fifty-five patient isolates and five healthy children isolates were HCMV-UL144 positive by PCR. Sequencing and HMA-SSCP analysis showed that significant strain-specific variability was present in the UL144 ORF. Phylogenetic analysis indicated that the nucleotide sequences could be separated into 3 major genotypes. Comparing between UL144 sequences and the corresponding symptoms showed that genotype 2 did not exist in megacolon isolates. And genotype 1 and 3 were the major types among microcephaly and jaundice isolates respectively.Conclusions HCMV-UL144 existed in most of low passage isolates and sequences were hypervariable. The UL144ORF and its predicted product with the high level of sequence variability in different kinds of isolates suggest that UL144ORF might play a role in HCMV infectivity and subsequent diseases.

    Asymptomatic bacteriuria, also called asymptomatic urinary infection, is a common finding in healthy women, and in women and men with abnormalities of the genitourinary tract. The characterization and introduction of the quantitative urine culture in the 1950s first allowed the reliable recognition of asymptomatic bacteriuria. The observations that a substantial proportion of patients with chronic pyelonephritis at autopsy had no history of symptomatic urinary infection, and the high frequency of pyelonephritis observed in pregnant women with untreated asymptomatic bacteriuria, supported a conclusion that asymptomatic bacteriuria was harmful. Subsequent screening and long term follow-up programs for asymptomatic bacteriuria in schoolgirls and women reported an increased frequency of symptomatic urinary tract infection for subjects with asymptomatic bacteriuria, but no increased morbidity from renal failure or hypertension, or increased mortality. Treatment of asymptomatic bacteriuria did not decrease the frequency of symptomatic infection. Prospective, randomized, comparative trials enrolling premenopausal women, children, elderly populations, patients with long term catheters, and diabetic patients consistently report no benefits with antimicrobial treatment of asymptomatic bacteriuria, and some evidence of harm. Several studies have also reported that antimicrobial treatment of asymptomatic bacteriuria increases the short term risk of pyelonephritis. Current investigations are exploring the potential therapeutic intervention of establishing asymptomatic bacteriuria with an avirulent Escherichia coli strain to prevent symptomatic urinary tract infection for selected patients.

    Background Cytomegalovirus (CMV) retinitis is the most severe intraocular complication that results in total retinal destruction and loss of visual acuity in patients with acquired immunodeficiency syndrome (AIDS). This study aimed to investigate the fundus characteristics, systemic manifestations and therapeutic outcomes of CMV retinitis associated with AIDS.Methods It was a retrospective case series. CMV retinitis was present in 39 eyes (25 patients). Best corrected visual acuities, anterior segment, fundus features, fundus fluorescence angiography (FFA) and CD4+ T-lymphocyte counts of the patients with CMV retinitis associated with AIDS were analyzed. Intravitreal injections of ganciclovir (400 μg) were performed in 4 eyes (2 patients).Results Retinal vasculitis, dense, full-thickness, yellow-white lesions along vascular distribution with irregular granules at the border, and hemorrhage on the retinal surface were present in 28 eyes. The vitreous was clear or mildly opaque.Late stage of the retinopathy was demonstrated in 8 eyes characterized as atrophic retina, sclerotic and attenuated vessels, retinal pigment epithelium (RPE) atrophy, and optic nerve atrophy. Retinal detachment was found in 3 eyes. The average CD4+ T-lymphocyte count in peripheral blood of the patients with CMV retinitis was (30.6±25.3) ×106/L (range,(0-85) × 106/L). After intravitreal injections of ganciclovir, visual acuity was improved and fundus lesions regressed.Conclusions CMV retinitis is the most severe and the most common intraocular complication in patients with AIDS. For the patients with yellow-white retinal lesions, hemorrhage and retinal vasculitis without clear cause, human immunodeficiency virus (HIV) serology should be performed. Routine eye examination is also indicated in HIV positive patients.

    Herpes zoster (HZ) is caused by VZV reactivation that is facilitated by a declined immunity against varicella-zoster virus (VZV), but also occurs in immunocompetent individuals. Cytomegalovirus (CMV) infection is associated with immunosenescence meaning that VZV-specific T-cells could be less responsive. This study aimed to determine whether CMV infection could be a risk factor for the development of HZ. CMV IgG serostatus was determined in stored serum samples from previously prospectively recruited ambulatory adult HZ patients in the UK (N = 223) in order to compare the results with those from UK population samples (N = 1545) by means of a logistic regression (controlling for age and gender). Furthermore, we compared the UK population CMV seroprevalence with those from population samples from other countries (from Belgium (N1 = 1741, N2 = 576), USA (N = 5572) and Australia (N = 2080)). Furthermore, CMV IgG titers could be compared between UK HZ patients and Belgium N2 population samples because the same experimental set-up for analysis was used. We found UK ambulatory HZ patients to have a higher CMV seroprevalence than UK population samples (OR 1.56 [1.11 2.19]). CMV IgG seropositivity was a significant risk factor for HZ in the UK (OR 3.06 [1.32 7.04]. Furthermore, high CMV IgG titers (exceeding the upper threshold) were less abundant in CMV-seropositive Belgian N2 population samples than in CMV-seropositive UK HZ patients (OR 0.51 [0.31 0.82]. We found CMV-seroprevalence to increase faster with age in the UK than in other countries (P < 0.05). We conclude that CMV IgG seropositivity is associated with HZ. This finding could add to the growing list of risk factors for HZ. PMID:25905443

    Full Text Available Human cytomegalovirus (hCMV has been described as an important etiological agent of intrauterine infection in women of childbearing age that causes congenital malformation. In the present study we examined 844 serum samples from women of child-bearing age for the presence of IgM and IgG antibodies against hCMV by Elisa technique. 764 out of 844 (93% of the cases were seropositive for hCMV-IgG and 45 (5.4% cases were seropositive for hCMV-IgM. An increase in the rate of IgG seroprevalance was associated with an increase in age and parity. The IgG seroprevalance rate was inversely proportional to increasing abortions. Intrestingly seasonal variation affected IgG seroprevalance. There was an increasing trend in IgM positivity rate with age in women less than 29 years. hCMV seroprevalence rate was higher in women from rural as compared to those of urban areas. Finally hCMV primary infections occured in 2.4 % of all pregnancis and it is estimated that up to 0.3% of all congenital disorders, through out Fars province, were due to hCMV. We suggest a role of child to mother hCMV transmission and sexual maturity as the most probable epidemiological factors of hCMV seroprevalence among women of child bearing age.

    Full Text Available Abstract Background Cytomegalovirus (CMV is a common opportunistic infection among HIV-infected individuals, a major source of serious complications among organ-transplant recipients, and a leading cause of hearing loss, vision loss, and mental retardation among congenitally infected children. Women infected for the first time during pregnancy are especially likely to transmit CMV to their fetuses. More children suffer serious disabilities caused by congenital CMV than by several better-known childhood maladies such as Down syndrome or fetal alcohol syndrome Methods Using CMV seroprevalence data from the nationally representative Third National Health and Nutrition Examination Survey, we estimated CMV incidence among the general United States population and among pregnant women. We employed catalytic models that used age-specific CMV seroprevalences as cumulative markers of past infections in order to derive estimates of three basic parameters: the force of infection, the basic reproductive rate, and the average age of infection. Our main focus was the force of infection, an instantaneous per capita rate of acquisition of infection that approximates the incidence of infection in the seronegative population. Results Among the United States population ages 12–49 the force of infection was 1.6 infections per 100 susceptible persons per year (95% confidence interval: 1.2, 2.4. The associated basic reproductive rate of 1.7 indicates that, on average, an infected person transmits CMV to nearly two susceptible people. The average age of CMV infection was 28.6 years. Force of infection was significantly higher among non-Hispanic Blacks (5.7 and Mexican Americans (5.1 than among non-Hispanic Whites (1.4. Force of infection was significantly higher in the low household income group (3.5 than in the middle (2.1 and upper (1.5 household income groups. Based on these CMV incidence estimates, approximately 27,000 new CMV infections occur among seronegative

    Full Text Available Background. Congenital intestinal lymphangiectasia is a disease which leads to protein losing enteropathy. Tortous, dilated lymphatic vessels in the intestinal wall and mesenterium are typical features of the disease. Clinical manifestations include malabsorption, diarrhea, steatorrhea, edema and effusions. Specific diet and medication are required for disease control. Case report. A 19-year old male patient was hospitalized due to diarrhea, abdominal swelling, weariness and fatigue. Physical examination revealed growth impairment, ascites, and lymphedema of the right hand and forearm. Laboratory assessment indicated iron deficiency anaemia, lymphopenia, malabsorption, inflammatory syndrome, and urinary infection. Enteroscopy and video capsule endoscopy demonstrated dilated lymphatic vessels in the small intestine. The diagnosis was confirmed by intestinal biopsy. The patient was put on high-protein diet containing medium-chain fatty acids, somatotropin and suportive therapy. Conclusion. Congenital intestinal lymphangiectasia is a rare disease, usually diagnosed in childhood. Early recognition of the disease and adequate treatment can prevent development of various complications.

    Congenital diaphragmatic hernia, despite advances in therapy, remains a complex condition with significant morbidity and mortality. The etiology of the disorder is still incompletely understood, though the pulmonary hypoplasia and pulmonary hypertension that develop secondarily must be overcome to improve survival. Prenatal US and fetal MRI have helped in the development of a greater understanding of this disease. Also with these modalities, measurement techniques have been developed in an attempt to provide prognosticators for the development of pulmonary hypoplasia and pulmonary hypertension. There is a broad range of approaches for performing these measurements, and variability among imaging centers is noted. Despite inconsistent approaches, these techniques have become the foundation for counseling and prenatal and postnatal therapy. It is hoped that with further research with prenatal US and fetal MRI and the development of innovative medical and surgical therapies that the morbidity and mortality of children with congenital diaphragmatic hernias can be significantly reduced.

    The management of congenital cataract is very different to the treatment of a routine age-related cataract. In adults, surgery may be delayed for years without affecting the visual outcome. In infants, if the cataract is not removed during the first year of life, the vision will never be fully regained after surgery. In adults, if the aphakia is not corrected immediately, it can be corrected later. In young children, if the aphakia is not corrected, the vision will never develop normally.

    No studies have compared toileting-specific behaviors of encopretic children with those of asymptomatic children and have controlled for environmental factors such as parental attitudes, parenting styles, and bathroom facilities. This study prospectively examined the toileting habits of 86 chronically encopretic children compared with those of 27 asymptomatic siblings and 35 asymptomatic nonsiblings. Although encopretic children experienced significantly more soiling than did controls, the total number of daily bowel movements passed in the toilet (+/-SD) was comparable in the three groups (.92 +/- .76 in encopretic children compared with 1.14 +/- .43 and 1.08 +/- .47 in siblings and nonsiblings, respectively). Encopretic children experienced pain with defecation more often than did controls. During the 14-day study period, encopretic children complained of pain on 2.75 +/- 4.03 days compared with .58 +/- 1.84 days among sibling controls and 2.31 +/- 3.21 days among nonsibling controls. The mean pain score in encopretic children was .76 +/- 1.00 compared with .05 +/- .15 and .26 +/- .38 among siblings and nonsiblings, respectively. All three groups of children sat on the toilet without parental prompting the same number of times each day. In summary, children with chronic encopresis do not seem to avoid toileting, and they exhibit toileting behaviors that are very similar to those of asymptomatic siblings as well as to those of nonsibling controls.

    Full Text Available Introduction. Syphilis is a sexually transmitted disease that is known as “the great imitator” due to its wide variety of clinical presentations, including ocular disorders. There has been an increase in the rate of syphilis in the United States, especially in persons with HIV. We report a case of optic perineuritis in an asymptomatic male secondary to central nervous system (CNS syphilis. Case Report. A 41-year-old man was found to have bilateral disc edema on a routine exam. Brain MRI was unremarkable, and lumbar puncture revealed a normal opening pressure, with an elevated cerebrospinal fluid white cell count. Orbit MRI showed optic nerve sheath expansion and enhancement, consistent with optic perineuritis. He tested positive for syphilis based on serum RPR and FTA-ABS. Conclusion. Ophthalmologic findings, including disc edema, may be the presenting features of CNS syphilis. Even in asymptomatic persons, perineuritis should be considered early, as diagnosis and treatment are imperative given the progressive nature of the disease.

    Full Text Available Introduction: Congenital spinal lipomas constitute an important group of lesions causing tethered cord syndrome. Management of these lesions is challenging and role of prophylactic surgery for these lesions is still controversial. Hence, current study was undertaken with the aim to evaluate the role of prophylactic surgery in the management of these lesions. Materials and Methods: A total of 147 consecutive patients, treated over a period of 10 years (January 2001-December 2010, are retrospectively analyzed. Results: In our study, 93 patients had conus lipomas, 26 had filum lipomas and 28 had only lipomeningomyelocele. Boys and girls were almost equally represented. The age of patients at the time of surgery ranged from 15 days to 34 years with an average of 62 months (5.2 years. Neurological deficits were present in 101 (68 patients. The patients with neurological deficits were older in comparison to those neurologically intact (average age 6.2 versus 2.8 years, respectively. Difference in age between the two groups was statistically significant (P value 0.03. Neurological deterioration was observed in 8 (5 patients following surgery, out of which six patients developed transient deterioration and only two, had persisting deficits. None of the neurologically asymptomatic patients developed persistent neurological deficits. In the symptomatic group, nine patients (9 showed improvement in neurological status after surgery. Conclusions: In author′s view, prophylactic surgery for congenital spinal lipomas is safe and effective. However, a well designed randomized controlled trial, to definitely and objectively prove the usefulness of prophylactic surgery is needed.

    Full Text Available OBJECTIVE: To estimate the seroprevalence of cytomegalovirus (CMV, Epstein Barr virus (EBV and varicella zoster virus (VZV among pregnant women in Bradford by ethnic group and country of birth. METHODS: A stratified random sample of 949 pregnant women enrolled in the Born in Bradford birth cohort was selected to ensure sufficient numbers of White UK born women, Asian UK born women and Asian women born in Asia. Serum samples taken at 24-28 weeks' gestation were tested for CMV IgG, EBV IgG and VZV IgG. Each woman completed a questionnaire which included socio-demographic information. RESULTS: CMV seroprevalence was 49% among the White British women, 89% among South Asian UK born women and 98% among South Asian women born in South Asia. These differences remained after adjusting for socio-demographic factors. In contrast, VZV seroprevalence was 95% among women born in the UK but significantly lower at 90% among South Asian women born in Asia. EBV seroprevalence was 94% overall and did not vary by ethnic group/country of birth. CONCLUSIONS: Although about half of White British women are at risk of primary CMV infection in pregnancy and the associated increased risk of congenital infection, most congenital CMV infections are likely to be in children born to South Asian women with non-primary infection during pregnancy. South Asian women born in South Asia are at risk of VZV infection during pregnancy which could produce congenital varicella syndrome or perinatal chickenpox. Differences in CMV and VZV seroprevalence by ethnic group and country of birth must be taken into account when universal immunisation against these viruses is contemplated.

    Full Text Available A 25-year old man presented with chronic low back pain for about 5 years due to mild congenital lumbar kyphosis (L1-L3 25° with congenital posterior wedge vertebra L2. Preoperative neurologic examination was normal. After posterior spinal fusion and instrumentation with moderate curve correction, the patient gradually developed the symptoms and signs of cauda equina syndrome due to intraoperative L2-3 disc herniation. After 5 days the patient underwent posterior decompression surgery and on the latest follow up visit at 2 years later, nearly all the motor power was recovered but the patient complained of occasional urinary incontinence and residual right leg paresthesia. In surgical treatment of congenital kyphosis, much attention should be paid to the presence of contemporaneous asymptomatic disc herniation.

  20. Properties of virion transactivator proteins encoded by primate cytomegaloviruses

    2009-05-01

    Full Text Available Abstract Background Human cytomegalovirus (HCMV is a betaherpesvirus that causes severe disease in situations where the immune system is immature or compromised. HCMV immediate early (IE gene expression is stimulated by the virion phosphoprotein pp71, encoded by open reading frame (ORF UL82, and this transactivation activity is important for the efficient initiation of viral replication. It is currently recognized that pp71 acts to overcome cellular intrinsic defences that otherwise block viral IE gene expression, and that interactions of pp71 with the cell proteins Daxx and ATRX are important for this function. A further property of pp71 is the ability to enable prolonged gene expression from quiescent herpes simplex virus type 1 (HSV-1 genomes. Non-human primate cytomegaloviruses encode homologs of pp71, but there is currently no published information that addresses their effects on gene expression and modes of action. Results The UL82 homolog encoded by simian cytomegalovirus (SCMV, strain Colburn, was identified and cloned. This ORF, named S82, was cloned into an HSV-1 vector, as were those from baboon, rhesus monkey and chimpanzee cytomegaloviruses. The use of an HSV-1 vector enabled expression of the UL82 homologs in a range of cell types, and permitted investigation of their abilities to direct prolonged gene expression from quiescent genomes. The results show that all UL82 homologs activate gene expression, and that neither host cell type nor promoter target sequence has major effects on these activities. Surprisingly, the UL82 proteins specified by non-human primate cytomegaloviruses, unlike pp71, did not direct long term expression from quiescent HSV-1 genomes. In addition, significant differences were observed in the intranuclear localization of the UL82 homologs, and in their effects on Daxx. Strikingly, S82 mediated the release of Daxx from nuclear domain 10 substructures much more rapidly than pp71 or the other proteins tested. All

    Full Text Available Infection with genital herpes simplex virus (HSV remains a common viral sexually transmitted disease, often subclinical and a major worldwide problem of women of reproductive age group. Herpes cervicitis is an unusual presentation of Herpes simplex virus infection in females. The finding of herpes cervicitis on routine pap smear of an asymptomatic woman on Intrauterine contraceptive device still further supports the need for increased awareness on the possibility of Herpes simplex virus infection among women, particularly those on Intrauterine contraceptive device. The index case is a 28 years old Nigerian female who was referred to our Special Treatment Clinic on account of an abnormal pap smear cytology which was in keeping with Herpes cervicitis. There was no history of genital ulcer in this patient; however ELISA for HSV 2 IgM was positive in her. We therefore describe a case of herpes cervicitis in an asymptomatic woman on intrauterine contraceptive device. This case highlights to clinicians the need to be aware of the possibility of this association and to carry out relevant investigations so as to identify and treat these patients appropriately. Therefore, there is a need to put in place adequate public health intervention strategy to prevent genital herpes in women of reproductive age group with a view to preventing the possibility of congenital herpes in subsequent pregnancy.

    Background: Rheumatic diseases involve multiple organs that are affected by immunological mechanisms.Treatment with corticosteroids and immunosuppressive agents may also increase the frequency of infection.Cytomegalovirus (CMV) is a widespread herpes virus and a well-recognized pathogen, which causes an opportunistic and potentially fatal infection in immunocompromised patients.This retrospective study aimed to investigate the clinical and laboratory characteristics of CMV pneumonia in patients with rheumatic diseases after immunosuppressive therapy in a single center in Shanghai, China.Methods: Eight hundred and thirty-four patients with rheumatic diseases who had undergone CMV-DNA viral load tests were included, and the medical records of 142 patients who were positive for CMV-DNA in plasma samples were evaluated.GraphPad Prism version 5.013 (San Diego, CA, USA) was used to conduct statistical analysis.The correlation between CMV-DNA viral loads and lymphocyte counts was assessed using the Spearman rank correlation coefficient test.Significance between qualitative data was analyzed using Pearson's Chi-squared test.The cut-offthresholds for CMV-DNA viral load and lymphocyte count were determined by receiver operating characteristic (ROC) curve analysis.Results: One hundred and forty-two patients had positive CMV viral load tests.Of these 142 patients, 73 patients with CMV pneumonia were regarded as symptomatic, and the other 69 were asymptomatic.The symptomatic group received higher doses ofprednisolone (PSL) and more frequently immunosuppressants than the asymptomatic group (P < 0.01).The symptomatic group had lower lymphocyte counts, especially CD4+ T-cells, than the asymptomatic group (P < 0.01).By ROC curve analysis, when CD4+ T-cell count was <0.39 × 109/L, patients with rheumatic diseases were at high risk for symptomatic CMV infection.The CMV-DNA load was significantly higher in the symptomatic patients than that in asymptomatic patients (P < 0

    The incidence of cytomegalovirus (CMV) reactivation/disease after autologous stem cell transplant (ASCT) is much lower than that after allogeneic stem cell transplantation. With the recent use of rituximab during cancer chemotherapy or conditioning regimens prior to transplantation, there has been an increasing concern of opportunistic infections including CMV. In the present study, we reviewed the patients undergoing ASCT from December 2007 to December 2013 to identify those developing CMV reactivation/disease. Out of the 978 patients who underwent ASCT at the Karmanos Cancer Institute, 239 patients were tested for symptomatic CMV reactivation based on clinical suspicion. Of the tested patients, 7/239 (2.9 %) were documented to have CMV reactivation within 90 days of ASCT. The median time to develop CMV viremia was 32 days from transplantation. Of the 239 patients tested, CMV viremia was detected in 3 out of 72 patients who received rituximab as compared to 4 out of 167 patients who did not. Three of these seven viremic patients were treated with anti-viral drugs; viremia resolved in all patients at a median of 24 days. Three patients were found to develop other bacterial and/or fungal infections following CMV viremia. Two of the seven patients died during 1-year follow-up, due to primary disease progression or Candida sepsis. None of the patients developed proven tissue-invasive CMV disease. The study did not evaluate the incidence of asymptomatic CMV infection/reactivation. Despite prior publications based on limited data, rituximab does not appear to contribute to an increased frequency of symptomatic CMV reactivation following ASCT. PMID:27225264

    Full Text Available Congenital malformation (CM will begin to emerge as one of the major childhood health problems .Treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. The aim of this study was to determine frequency of CM in Yazd central city of the Islamic Republic of Iran to find out if there has been any difference in the rate and types of CM in this area. This descriptive-observational study carried on 4800 births delivered at all maternity hospitals in Yazd from October 2003 to June 2004. Prevalence of CM was 2.83% (2.86 % in male and 2.68 % in female out of the 136 cases 69(51.88% were males and 64 (48.12% were females and 3 with ambiguous genitalia. Positive family history of CM in sibling was in only 6 cases (4.41%.Overall, musculoskeletal (0.83%, central nerv-ous system (0.47% and genital system (0.37% were accounted as the most common. Frequency of CM was more seen in still birth (12.5% as in comparison to live birth (2.71%. There was not statistical difference be-tween prevalence of CM and neonatal's gender, gestational age, birth order and mother's age, drug ingestion, illness and parental consanguinity. In this study the overall prevalence of congenital malformation among the newborn was higher than those previous reported in Iran and determining the causes of this difference needs more extensive studies.

    Full Text Available Nonclassic congenital adrenal hyperplasia (NCAH due to P450c21 (21-hydroxylase deficiency is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and “on-time” puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

    Congenital anterior urethral diverticulum (CAUD) may be found all along the anterior urethra and may present itself at any age, from infant to adult. Most children with this condition present with difficulty in initiating micturition, dribbling of urine, poor urinary stream, or urinary tract infection. A careful history will reveal that these children never had a good urinary stream since birth, and the telltale sign is a cystic swelling of the penile urethra. In this paper, we present two cases of CAUD that were managed by excision of the diverticulum with primary repair. PMID:26328174

    2007-02-01

    Full Text Available Cytomegalovirus (CMV infection is a relatively late complication of AIDS. Like other viruses contributing to co-morbidity of HIV infection, cytomegalovirus has the propensity to cause multiorgan involvement. We report the case of a 34-year-old seropositive man who presented with bilateral lower limb weakness and symptomatic pallor. He was already on antiretroviral drugs for a month prior to presentation. Detailed clinical examination and laboratory investigations revealed cytomegalovirus polyradiculoneuropathy associated with bone marrow dysplasia. Dysplasia of haematopoeitic cell lines occurs in 30% to 70% of HIV infected patients, and is often indistinguishable from myelodysplastic syndrome. However, in our case, the bone marrow picture reverted back to normal with treatment of the CMV infection, pointing to a possible role of CMV as the causative agent of bone marrow dysplasia. Moreover, CMV has been incriminated as a pathogen producing the immune reconstitution inflammatory syndrome. The onset of the disease in our case one month after initiation of HAART strongly raises the possibility of this being a case of CMV related IRIS. This is the first reported case where IRIS has presented with CMV polyradiculoneuropathy and bone marrow dysplasia. We would like to highlight that in today's era of HIV care, clinicians should be aware of the possibility of multiorgan involvement by CMV, for appropriate management of this disease in the background of AIDS.

The precise diagnosis requires detailed clinical examination and electrophysiological findings. This case report presents two male patients with congenital nystagmus examined longitudinally from the age of six months until 17-18 years of age. Clinical and electrophysiological protocols were detailed. The first results showed electronegative electroretinography in the two cases and examination combined with electroretinographic findings helped us to make the diagnosis of Congenital Night Stationary Blindness (CSNB. This diagnosis was confirmed by genetic studies. CSNB is interesting to study because through electrophysiological findings, it enables a better understanding of the physiology of neural transmission in the outer part of the retina.Keywords: Congenital nystagmus, negative electroretinography, congenital night stationary blindness

  14. Congenital Leukemia in Down's syndrome

    International Nuclear Information System (INIS)

    Congenital Leukemia is a condition and often associated with fatal outcome/sup 1/. Most of the neonatal cases reported have acute non-lymphoblastic leukemia, in contrast to the predominance of acute lymphoblastic leukemia found in later childhood. congenital leukemia is occasionally associated with number of congenital anomalies and with chromosomal disorders such as Down's syndrome. Subtle cytogenetic abnormalities may occur more commonly in the affected infants and their parents, when studied with newer cytogenetic techniques/sup 2/. Inherent unstable hematopoieses resulting from chromosomal aberration in children with Downs's syndrome can present with transient myeloproliferative disorder, mimicking leukemia which undergoes spontaneous recovery/sup 3/. Only few cases of congenital leukemia with Downs syndrome, presented as congenital leukemia. (author)

  15. The relationship between brain atrophy and asymptomatic cerebral lesions

    International Nuclear Information System (INIS)

    In order to clarify the relationship between brain atrophy and asymptomatic cerebral lesions, total of 235 subjects (130 males and 105 females), who had neither neurologic deficits nor organic lesions on cerebral computed tomography, were studied. The subjects' ages ranged from 40 to 86 years (mean 66). They were divided into two groups: 90 controls without hypertension or diabetes mellitus (Group C), and 145 patients with essential hypertension (Group H). Brain atrophy was diagnosed using the caudate head index (CHI). Asymptomatic cerebral lesions on magnetic resonance imaging were defined as asymptomatic lacunae and white matter lesions. Caudate head index was higher in Group H than it was in Group C, and CHI in both groups was significantly correlated with the number of asymptomatic lacunae and the severity of white matter lesions on magnetic resonance imaging. These results indicate that brain atrophy may progress along with asymptomatic cerebral lesions. (author)

    As a whole the congenital defects constitute an important section of the medical attention affecting near 3% of the population. A 15% of spontaneous abortions take place of which the greater frequency corresponds to the chromosome anomalies (25%) and the monogenic mutations (20%) and in a lesser extent to the effects of teratogenic agents. Between the genetic causes determining the congenital defects the mutations that affect genes acting in the early stages of development occupy a main place. These alterations can affect to homeotic genes or monogenic systems that act during the critical phases of the organogenesis. It seems evident that an alteration in the expression of a necessary gene for the appearance of a morphogenetic change constitutes the angular stone to understand resurging of a malformation or discapacity. In the last years has been demonstrated the importance of the teratogenic or environmental agents on the delicate internal physiological balance during the critical stages of the development. In this context must be included the inductive environmental factors inducing epigenetic modifications in the early stage of the development of the embryos produced by fertilization in vitro.

    Type I muscle fiber atrophy in childhood can be encountered in a variety of neuromuscular disorders. Congenital fiber type disproportion (CFTD) is one such condition which presents as a nonprogressive muscle weakness. The diagnosis is often made after excluding other differential diagnostic considerations. We present a 2-year-9-month-old full term boy who presented at 2 months with an inability to turn his head to the right. Over the next couple of years, he showed signs of muscle weakness, broad based gait and a positive Gower's sign. He had normal levels of creatine kinase and normal electromyography. A biopsy of the vastus lateralis showed a marked variation in muscle fiber type. The adenosine triphosphate (ATP)-ase stains highlighted a marked type I muscle atrophy with rare scattered atrophic type II muscle fibers. No abnormalities were observed on the nicotinamide adenine dinucleotide (NADH), succinate dehydrogenase (SDH) or cytochrome oxidase stained sections. Ragged red fibers were not present on the trichrome stain. Abnormalities of glycogen or lipid deposition were not observed on the periodic acid-Schiff or Oil-Red-O stains. Immunostaining for muscular dystrophy associated proteins showed normal staining. Ultrastructural examination showed a normal arrangement of myofilaments, and a normal number and morphology for mitochondria. A diagnosis of CFTD was made after excluding other causes of type I atrophy including congenital myopathy. The lack of specific clinical and genetic disorder associated with CFTD suggests that it is a spectrum of a disease process and represents a diagnosis of exclusion. PMID:26526626

    2007-03-01

    From 1975 to 2004 a total of 38 children handicapped by congenital multiple arthrogryposis were cared for. The congenital joint contractures demand a major effort in terms of surgical reconstruction. In the case of distal arthrogryposis the chances that patients will be able to walk without help are good, while those with amyoplasia are likely to be dependent on mobility aids throughout their lives. The ultimate goal of treatment for patients is to develop into self-confident adults who can cope with life despite their handicaps. The hip in arthrogryposis shows variable forms of pathology, ranging from the almost normal hip to hip contractures with dislocation. Its treatment has some limited advantages, but hardly improves mobility. The knee contractures are actively treated to allow patients to sit, stand and walk better. The club foot and the rocker-bottom foot need sophisticated conservative and operative treatments. If conservative manipulation of bilateral extension contractures of the elbow fails operative treatment is carried out on the dominant side. For shoulder, hand and finger contractures conservative manipulation brings about little improvement, and surgical approaches help hardly at all. PMID:17323063

    A congenital extrahepatic portosystemic shunt (CEPS) is uncommon. A type 1 CEPS exists where there is absence of intrahepatic portal venous supply and a type 2 CEPS where this supply is preserved. The diagnosis of congenital portosystemic shunt is important because it may cause hepatic encephalopathy. To describe the clinical and imaging features of three children with CEPS and to review the cases in the published literature. The diagnostic imaging and medical records for three children with CEPS were retrieved and evaluated. An extensive literature search was performed. Including our cases, there are 61 reported cases of CEPS, 39 type 1 and 22 type 2. Type 1 occurs predominantly in females, while type 2 shows no significant sexual preponderance. The age at diagnosis ranges from 31 weeks of intrauterine life to 76 years. Both types of CEPS have a number of associations, the most common being nodular lesions of the liver (n=25), cardiac anomalies (n=19), portosystemic encephalopathy (n=10), polysplenia (n=9), biliary atresia (n=7), skeletal anomalies (n=5), and renal tract anomalies (n=4). MRI is recommended as an important means of diagnosing and classifying cases of CEPS and examining the associated cardiovascular and hepatic abnormalities. Screening for CEPS in patients born with polysplenia is suggested. (orig.)

    We report on a 13-year-old male who had acute enteroviral encephalitis causing cerebellar symptoms at the age of 10 years. Magnetic resonance imaging (MRI) showed no abnormalities. Clinically he appeared to be recovered completely after 6 months. Twenty-three months after the recovery, MRI was performed because he presented with slight lower-limb and truncal ataxia experienced as lack of foot coordination while playing football or riding a bicycle. MRI demonstrated severe cerebellar atrophy. Clinically he recovered completely in 10 days. Only sophisticated electrophysiological methods revealed cerebellar dysfunction. The case provides evidence for the plasticity of cerebellar regulatory structures involved in the coordination of fine movements. It seems that in childhood the slow, isolated disintegration of cerebellar systems can be compensated for by upper thalamic or telencephalic connections, in a similar way to a congenital deficit of the cerebellum.

    Ganciclovir therapy was given intravenously to 20 children with cytomegalovirus (CMV)-associated liver disease, of whom 6 were immunocompetent and 14 were immunocompromised (9 had AIDS and 5 had solid tumors). Immunocompetent children had isolated liver disease diagnosed at birth (4 children), or systemic congenital CMV infection including liver disease (2 children). Ganciclovir was used following two regimens: A) 5 mg/kg twice daily for 8 to 86 days (mean 21); B) 7.5 mg/kg twice daily for 14 days followed by 10 mg/kg three times weekly for three months. CMV infection was diagnosed by viral isolation, detection of viral antigens, and/or CMV DNA from blood and urine. All immunocompetent children had negative CMV culture and CMV DNA detection from blood and/or urine after 14 weeks of treatment. However, the three children who were treated with regimen B showed normal ALT levels at the end of the maintenance course, whereas the children who received ganciclovir with regimen A had normal ALT levels only after about 1 year. All children with tumors initiated regimen B, but only three, who had negative CMV detection and markedly decreased ALT levels, received full treatment; of the remaining two children, one recovered after only an initial course, and the other had therapy interrupted because of hepatic failure and died 9 days later. In contrast, the children with AIDS received several ganciclovir courses for different periods at the lower dosage: they generally improved during treatment but did not recover completely, and five children died with active CMV infections. Based on our study, CMV-associated liver disease can be efficiently treated with ganciclovir both in immunocompetent and immunodeficient children. However, a single ganciclovir course including a higher dosage and prolonged therapy appeared to be more effective than several courses with lower dosages. PMID:9349303

  3. Knowledge and practices of obstetricians and gynecologists regarding cytomegalovirus infection during pregnancy--United States, 2007.

    Science.gov (United States)

    2008-01-25

    In the United States, congenital cytomegalovirus (CMV) infection occurs in approximately 1 in 150 live births, leading to permanent disabilities (e.g., hearing loss, vision loss, and cognitive impairment) in approximately 1 in 750 live-born children. A common mode of CMV transmission to a pregnant woman is through close contact with infected bodily fluids such as urine or saliva, especially from young children. Because no vaccine is available and treatment options are limited, renewed attention has been given to prevention of CMV infections among pregnant women through traditional infection-control practices, such as good hand hygiene. These practices have been encouraged by organizations such as CDC and the American College of Obstetricians and Gynecologists (ACOG), which recommend that obstetricians and gynecologists (OB/GYNs) counsel women on careful handling of potentially CMV-infected articles, such as diapers, and thorough hand washing after close contact with young children. Despite this increased emphasis on avoiding infection during pregnancy, few women are aware of CMV infection and how it can be prevented. During March-May 2007, ACOG surveyed a national sample of OB/GYNs to assess their knowledge and practices regarding CMV infection prevention. This report describes the results of that survey, which indicated that fewer than half (44%) of OB/GYNs surveyed reported counseling their patients about preventing CMV infection. These results emphasize the need for additional training of OB/GYNs regarding CMV infection prevention and for a better understanding of the reasons that physician knowledge regarding CMV transmission might not result in patient counseling.

    Background Congenital cytomegalovirus (CMV) is a leading cause of disability, including sensorineural hearing loss, developmental delay, and mental retardation. Although the seroprevalence of CMV and associated exposure and behavioral risk factors have been reported in adolescent females, limited data exists in males. Method Serum was obtained from males (aged 12–17 years) from 6/2006 – 7/2007 in Cincinnati, OH, Galveston, TX, and Nashville, TN and tested for CMV IgG antibody using a commercial assay. Participants completed a computer assisted screening interview to assess seven risk categories. Results A total of 397 adolescent males were screened and 165 (47%) were seropositive. African American race, older age, and exposure to children ≤3 years of age in the home were significant predictors of CMV infection in the univariate analysis. Hispanic ethnicity, group living situations, saliva sharing behaviors, and intimate sexual contact were not associated with CMV infection. However, among those with a history of sexual contact, the number of life time partners was associated with CMV. In the final multivariate model, CMV seroprevalence was significantly higher in African American subjects (OR 1.99 (95% CI [1.27, 2.95]) and subjects >14 years of age (OR 1.1 (95%CI [1.00, 1.28]. With each additional risk factor, males had a 1.6x increased risk of CMV. Conclusions This study indicates that CMV infections are common in adolescent males, increase with age, and are associated with African American race. Further study is needed to understand these risk factors in preparation for a CMV vaccine targeted at both adolescent males and females. Summary This study indicates CMV infections are common in adolescent males, increase with age, and are associated with African Americans. Further study is needed to understand these risk factors in preparation for a CMV vaccine targeted at adolescent males and females. PMID:20936976

    Human cytomegalovirus DNA was isolated from infected cells by the Hirt method (B. Hirt, J. Mol. Biol. 26:365-369, 1967). The restriction endonuclease cleavage patterns of DNA obtained in this manner were comparable with those of DNA extracted from purified virions. The "Hirt supernatants" were satisfactory for identifying individual cytomegalovirus strains by their DNA fingerprinting.

    2016-01-01

    Introduction: Management guidelines were created to screen and manage asymptomatic renal stones in U.S. astronauts. The risks for renal stone formation in astronauts due to bone loss and hypercalcuria are unknown. Astronauts have a stone risk which is about the same as commercial aviation pilots, which is about half that of the general population. However, proper management of this condition is still crucial to mitigate health and mission risks in the spaceflight environment. Methods: An extensive review of the literature and current aeromedical standards for the monitoring and management of renal stones was done. The NASA Flight Medicine Clinic's electronic medical record and Longitudinal Survey of Astronaut Health were also reviewed. Using this work, a screening and management algorithm was created that takes into consideration the unique operational environment of spaceflight. Results: Renal stone screening and management guidelines for astronauts were created based on accepted standards of care, with consideration to the environment of spaceflight. In the proposed algorithm, all astronauts will receive a yearly screening ultrasound for renal calcifications, or mineralized renal material (MRM). Any areas of MRM, 3 millimeters or larger, are considered a positive finding. Three millimeters approaches the detection limit of standard ultrasound, and several studies have shown that any stone that is 3 millimeters or less has an approximately 95 percent chance of spontaneous passage. For mission-assigned astronauts, any positive ultrasound study is followed by low-dose renal computed tomography (CT) scan, and flexible ureteroscopy if CT is positive. Other specific guidelines were also created. Discussion: The term "MRM" is used to account for small areas of calcification that may be outside the renal collecting system, and allows objectivity without otherwise constraining the diagnostic and treatment process for potentially very small calcifications of uncertain

    Full Text Available Primary illness with cytomegalovirus leads to latent infection with possible reactivations especially in the immunocompromised patients. Toxic epidermal necrolysis is an immune mediated cytotoxic reaction. A fifty years old female diabetic hypertensive patient with end stage renal disease was admitted with fever of unknown origin, constitutional symptoms, vague upper gastrointestinal symptoms and skin rash. Upper gastrointestinal endoscopic biopsy confirmed her diagnosis with cytomegalovirus esophagitis and duodenitis. Cytomegalovirus immunoglobulin M and immunoglobulin G levels were negative but polymerase chain reaction showed fulminant viremia. Biopsy of the skin rash was consistent with toxic epidermal necrolysis. Despite treatment with Ganciclovir, intravenous immunoglobulins, and granulocyte colony stimulating factor the patient’s condition rapidly deteriorated and she died due to multiorgan failure, disseminated intravascular coagulopathy and overwhelming sepsis. Probably there is a true association linking toxic epidermal necrolysis to fulminant reactivation of cytomegalovirus. The aim of this anecdote is reporting a newly recognized presentation of cytomegalovirus.

    Full Text Available Devi Dayal, Rajendra Prasad Department of Pediatrics, Pediatric Endocrinology and Diabetes Unit, Postgraduate Institute of Medical Education and Research, Chandigarh, India Abstract: Congenital hypothyroidism (CH, the most common pediatric endocrine disorder with an estimated prevalence of 1:2,000 to 1:4,000, is an under-recognized problem in countries without routine newborn screening (NBS programs. Thyroid dysgenesis (TD is the most common cause of primary CH accounting for approximately 85% of all cases; most of the remaining patients have dyshormonogenesis. Transient CH and CH with eutopic gland, are increasingly being identified after introduction of routine NBS. The clinical features of CH are often subtle resulting in delayed diagnosis and eventually poor intellectual outcome. In developed countries, detection by NBS and early initiation of treatment has largely eliminated the intellectual disability caused by this disorder. The lower screening thyroid stimulating hormone (TSH cutoff and changes in birth demographics in some countries have been associated with an increase in the reported incidence of CH. However, the additional cases detected by the lower TSH cutoff tend to have either milder or transient hypothyroidism. Diagnosis of CH is made on the basis of serum concentrations of TSH and thyroxine (T4. Thyroid ultrasound, radionuclide scintigraphy, serum thyroglobulin (TG levels and specific genetic tests help ascertaining the exact etiological diagnosis. Non-availability of later tests should not deter the pediatrician from initiation of treatment. Age at initiation of treatment and starting dose of levothyroxine are critical factors that determine the long-term outcome. Higher doses of levothyroxine at 10–15 µg/kg/day are required in infants, with titration based on T4 and TSH levels, which are repeated frequently. Coexistence of other congenital anomalies in children with CH adds to the morbidity. Approximately 70% of babies

  12. Unsuspected urological anomalies in asymptomatic cryptorchid boys

    International Nuclear Information System (INIS)

    In a period of 6 years 144 asymptomatic boys with cryptorchidism, of mean age 7 ± SD 3.5 years, underwent orchiopexy. None of these boys referred to a history of a known urological anomaly, urinary tract infection haematuria, palpable mass in the renal region, bladder extrophy, epispadias, hypospadias or anorectal malformation. On the third day after orchiopexy an intravenous pyelography was done in every boy following testicular protection against irradiation. Ultrasonic investigation was not available at that time. There were minor urological abnormalities in 36 (25%) boys and major ones in 8 (5.5%) boys. A major anomaly is defined as one resulting in significant loss of renal substance (one case of single kidney and three cases of unilateral renal hypoplasia), or requiring surgical correction for conservation of the renal substance (one case of ureterocele, two cases of pelviureteric stenosis and one case of vesicoureteric stenosis with ipsilateral hydronephrosis). The unsuspected major urological abnormalities are usually ipsilateral to the more undescended testis. They may be associated with a hernia and are more frequent in bilateral cryptorchidism. In conclusion we encourage the routine use of IVP, or ultrasonic investigation or dynamic renal scanning (99mTc-DTPA), if it is possible, in all patients undergoing orchiopexy for the detection of an unsuspected major renal anomaly.

  13. Asymptomatic cerebral infarction examined by magnetic resonance imaging (MRI)

    International Nuclear Information System (INIS)

    To find the real incidence and risk factors in asymptomatic cerebral infarction, a retrospective review was made on magnetic resonance (MR) images, which were obtained from 713 outpatients seen at the Geriatrics Research Institute Hospital between March and November of 1990. The criteria for asymptomatic cerebral infarction are: high signal intensity areas larger than 3 mm in diameter on T2-weighted image; no history of stroke; no neurological and psychological signs or symptoms with or without subjective symptoms. Symptomatic cerebral stroke was defined as stroke episodes associated with neurological signs and infarction lesions on CT or MR imaging. Of a total of 713 patients, 215 (30.2%) had symtomatic cerebral infarction and 384 (53.9%) had no cerebral lesions. The incidence of asymptomatic cerebral infarction increased with aging. Cerebral risk factors, i.e. hypertension, atrial fibrillation, and diabetes mellitus, were more significantly common in both symptomatic and asymptomatic groups than the normal control group. In the group of asymptomatic patients, T2-weighted images showed hyperintensity in the corona radiata in 60.9%, in the frontal lobe in 32.1%, in the semioval center in 28.8%, and in the basal ganglia in 23.7%. Periventricular hyperintensity was present in 124 of all 713 patients (17.4%). Common complaints in asymptomatic patients were headache (40.0%), dizziness (14.4%), and neck muscle contraction (9.8%). In conclusion, MR imaging may contribute to manage asymptomatic patients. (N.K.)

    Nasal airway obstruction is a potentially life-threatening condition in the newborn. Neonates are obligatory nasal breathers. The pyriform aperture is the narrowest, most anterior bony portion of the nasal airway, and a decrease in its cross-sectional area will significantly increase nasal airway resistance. Congenital nasal pyriform aperture stenosis (CNPAS) is a rare, unusual form of nasal obstruction. It should be considered in the differential diagnosis of any neonate or infant with signs and symptoms of upper airway compromise. It is important to differentiate this level of obstruction from the more common posterior choanal stenosis or atresia. CNPAS presents with symptoms of nasal airway obstruction, which are often characterized by episodic apnea and cyclical cyanosis. (orig.)

    Full Text Available Primary sporadic congenital hypothyroidism (CH is the most common cause of hypothyroidism infancy early childhood in iodine sufficient region. Screening for neonatal CH began in 1970s. The rationale and reason for neonatal screening for CH (NSCH are well established. It is mandatory in most developed countries along with the screen for metabolic disorder. The possibility of measuring TSH and thyroid hormones in cord blood paved the way for newborn screening (NS for CH. Worldwide it is estimated that 25% of the live born population of 130 million babies undergo NSCH. Klein et al., by 1972 had shown improved CNS prognosis in CH treated by age 3 months. NSCH has largely eradicated the severe irreversible neurodevelopmental damage and reversed the chances of growth failure in infancy and early childhood.

    This report describes an unusual example of congenital mesoblastic nephroma cellular variant that presented in a 1-week-old neonate as a multicystic tumor of the kidney. Extensive pseudocystic cavitation resulted from progressive accumulation of ground substance in a loosely myxoid tissue composed of stellate- and spindle-shaped cells that compressed and infiltrated renal tissue. The cells of the tumor were positive for vimentin and smooth muscle actin. The patient is alive and well 16 years after surgery. Differential diagnosis from segmental cystic dysplasia, cystic intralobar nephrogenic rest, cystic nephroma, cystic partially differentiated nephroblastoma, cystic nephroblastoma, and cystic clear cell sarcoma of the kidney, all of which may present at this age, is discussed.

    International Nuclear Information System (INIS)

    The ears of 47 selected patients with congenital sensorineural hearing loss were examined with complex-motion tomography. The patients were divided into 3 general categories: those with a recognized syndrome, those with sensorineural hearing loss unrelated to any known syndrome, and those with microtia. A great variety of inner ear anomalies was detected, but rarely were these characteristic of a particular clinical entity. The most common finding was the Mondini malformation or one of its variants. Isolated dysplasia of the internal auditory canal or the vestibular aqueduct may be responsible for sensorineural hearing loss in some patients.

    @@ Drs. Rigatem, Rigatelli, and Trivellato present a complete retrospective review of the prevalence of congenital coronary abnormalities in a cohort of consecutive adult patients catheterized at their institution and compare them to younger patients < 65 years of age.They review in detail the clinical implications of these findings and then offer an algorithm for management. This article is particularly timely and significant as we move into an era of non-invasive coronary imaging with CT,MRI, and improved echo that will allow ns to make these diagnoses more often and with greater accuracy in younger patients. This will have a significant impact on the nanagement of symptomatic patients diagnosed at catheterization but also on asymptomatic patients diagnosed on screening evaluations.

  20. Spontaneous pneumothorax in a teenager with prior congenital pulmonary airway malformation

    Full Text Available Congenital pulmonary airway malformation (CPAM, previously referred to as congenital cystic adenomatoid malformation (CCAM, is a developmental malformation of the lower respiratory tract and the most commonly reported congenital lung lesion. Affected patients typically present with respiratory distress in the neonatal period from expanding cysts and resulting compression of surrounding lung parenchyma. However, some patients also remain asymptomatic until later in life. In this report, we present a case of CPAM requiring emergent left lower lobectomy at the first day of life that remained asymptomatic until the patient developed a spontaneous pneumothorax 18 years later. Our patient's presentation with an isolated spontaneous pneumothorax at age 18 does not appear to have been previously reported. In addition, there are several aspects of this case that represent atypical features of CPAM. After an extensive literature search, few reports exist describing any long-term complications of CPAM following neonatal lobectomy. Chest imaging in our patient demonstrated residual left basilar bullae and there was a moderate fixed obstructive/restrictive defect on pulmonary function testing. His risk for recurrent pneumothorax or infectious complications is unknown based on minimal published information on long-term outcomes or complications in patients with resected CPAM lesions. We conclude that follow up of all CPAM patients should include an evaluation for evidence of residual lung disease both with spirometric testing and chest imaging. Furthermore, concern for infectious complications or symptomatic obstructive lung disease should likewise be considered.

  8. Asymptomatic myocardial ischemia following cold provocation

    International Nuclear Information System (INIS)

    Cold is thought to provoke angina in patients with coronary disease either by an increase in myocardial demand or an increase in coronary vascular resistance. We investigated and compared the effects of cold pressor stimulation and symptom-limited supine bicycle exercise on regional myocardial perfusion in 35 patients with stable angina and coronary disease and in 10 normal subjects. Regional myocardial perfusion was assessed with positron emission tomography and rubidium-82. Following cold pressor stimulation 24 of 35 patients demonstrated significant abnormalities of regional myocardial perfusion with reduced cation uptake in affected regions of myocardium: 52 +/- 9 to 43 +/- 9 (p less than 0.001 vs normal subjects). Among these 24 patients only nine developed ST depression and only seven had angina. In contrast, 29 of 35 patients underwent supine exercise, and abnormal regional myocardial perfusion occurred in all 29, with a reduction in cation intake from 48 +/- 10 to 43 +/- 14 (p less than 0.001 vs normal subjects). Angina was present in 27 of 29 and ST depression in 25 of 29. Although the absolute decrease in cation uptake was somewhat greater following cold as opposed to exercise, the peak heart rate after cold was significantly lower than that after exercise (82 +/- 12 vs 108 +/- 16 bpm, p less than 0.05). Peak systolic blood pressures after cold and exercise were similar (159 +/- 24 vs 158 +/- 28). Thus, cold produces much more frequent asymptomatic disturbances of regional myocardial perfusion in patients with stable angina and coronary disease than is suggested by pain or ECG changes

    Full Text Available BACKGROUND Almost all patients presenting with chronic hyperamylasemia undergo an expensive, long, difficult and often repeated diagnostic workup even if this occurrence is not associated with symptoms or with known pancreatotoxic factors. This is in relationship with the poor knowledge that, beside hyperenzymemia secondary to pancreatic diseases and systemic illnesses, various non-pathological forms of chronic hyperamylasemia can occur in clinical practice. AIM OF THE STUDY This study was addressed to assess the clinical characteristics of patients presenting with chronic hyperamylasemia unrelated to pancreatic diseases (CHUPD. PATIENTS AND METHODS Data of all patients with CHUPD were retrospectively reviewed (June 1997-March 2007. Forty patients were included in the study; median follow- up was 33 months (range 3-84 months. CHUPD was secondary to: a chronic benign pancreatic hyperamylasemia, 16 patients (40%; b macroamylasemia, 15 patients (37.5%; c salivary hyperamylasemia, 9 patients (22.5%. Gilbert’s syndrome was present in 13 patients (32.5%; 8 with macroamylasemia and hyperdyslipidemia in 8 patients (20%; 5 with chronic benign pancreatic hyperamylasemia. Diagnostic exams (all in the normal range performed before our observation were: Ca19-9 serum level in 37/40 (92.5%, ultrasonography and computed tomography-scan in all patients, endoscopic retrograde cholangiopancreatography in 21/40 (52.5%, abdominal magnetic resonance in 14/40 (35%. Previous diagnosis in these asymptomatic subjects were: chronic pancreatitis in 26 cases (65%; recurrent pancreatitis in 10 cases (25%; the remaining 4 patients (10% were addressed without a specific diagnosis. CONCLUSIONS In clinical practice, the occurrence of an unexplained chronic hyperamylasemia very often allows to an unappropriate diagnostic workup due to the poor familiarity with CHUPD conditions.

    Full Text Available CONTEXT: Alcoholism may interfere with nutritional status, but reports are often troubled by uncertainties about ingested diet and organ function, as well as by ongoing abuse and associated conditions. OBJECTIVE: To identify nutritional and body compartment changes in stable alcoholics without confounding clinical and dietetic variables, a prospective observational pilot study was designed. Three well-matched populations were considered: subjects with chronic alcoholic pancreatitis, alcoholics without visceral disease, and healthy never-drinking adults (controls. METHODS: Subjects (n = 60 were asymptomatic males with adequate diet, no superimposed disease or complication, and alcohol-free for at least 6 months. After exclusions, 48 patients were compared. Variables encompassed dietary recall, bioimpedance analysis, biochemical profile and inflammatory markers. Main outcome measures were body fat, lean body mass, serum lipids, C-reactive protein, and selected minerals and vitamins. RESULTS: Both alcoholic populations suffered from reduced lean body mass (P = 0.001, with well-maintained body fat.Magnesium was depleted, and values of vitamin D and B12 correlated with alcohol abuse. LDL and total cholesterol was increased in alcoholics without pancreatitis (P = 0.04, but not in those with visceral damage. C-reactive protein and serum amyloid A correlated with duration of excessive drinking (P = 0.01. CONCLUSIONS: Undernutrition (diminished lean body mass, risk of magnesium and vitamin deficiencies contrasted with dyslipidemia and increased cardiovascular risk. This second danger was masked during chronic pancreatitis but not in alcoholics without visceral disease. Further studies should focus special requirements of this population.

    Full Text Available Cytomegalovirus (CMV infection is an important cause of morbidity and mortality in immunosuppressed patients. CMV infection is mostly encountered in children undergoing high-dose chemotherapy and transplantation. Though the chemotherapy for solid tumor is an immunosuppressed state, CMV infection has been reported infrequently in children with solid tumors. In this paper, a child diagnosed with neuroblastoma who was treated with conventional chemotherapy and developed CMV pneumonia is presented. The patient was treated with intravenous ganciclovir in the pediatric intensive care unit, but died one week later.

    Co-evolution has been shown to result in an adaptive reciprocal modification in the respective behaviors of interacting populations over time.In the case of host-parasite co-evolution,the adaptive behavior is most evident from the reciprocal change in fitness of host and parasite-manifested in terms of pathogen survival versus host resistance.Cytomegaloviruses and their hosts represent a pairing of populations that has co-evolved over hundreds of years.This review explores the pathogenetic consequences emerging from the behavioral changes caused by co-evolutionary forces on the virus and its host.

    AIM: To study the clinical characteristics, diagnosis and surgical treatment of congenital bronchoesophageal fistulae in adults. METHODS: Eleven adult cases of congenital bronchoesophageal fistula diagnosed and treated in our hospital between May 1990 and August 2010 were reviewed. Its clinical presentations, diagnostic methods, anatomic type, treatment, and follow-up were recorded. RESULTS: Of the chief clinical presentations, nonspecific cough and sputum were found in 10 (90.9%), recurrent bouts of cough after drinking liquid food in 6 (54.6%), hemoptysis in 6 (54.6%), low fever in 4 (36.4%), and chest pain in 3 (27.3%) of the 11 cases, respectively. The duration of symptoms before diagnosis ranged 5-36.5 years. The diagnosis of congenital bronchoesophageal fistulae was established in 9 patients by barium esophagography, in 1 patient by esophagoscopy and in 1 patient by bronchoscopy, respectively. The congenital bronchoesophageal fistulae communicated with a segmental bronchus, a main bronchus, and an intermediate bronchus in 8, 2 and 1 patients, respectively. The treatment of congenital bronchoesophageal fistulae involved excision of the fistula in 10 patients or division and suturing in 1 patient. The associated lung lesion was removed in all patients. No long-term sequelae were found during the postoperative follow-up except in 1 patient with bronchial fistula who accepted reoperation before recovery. CONCLUSION: Congenital bronchoesophageal fistula is rare in adults. Its most useful diagnostic method is esophagography. It must be treated surgically as soon as the diagnosis is established.

    Human cytomegalovirus (hCMV) is a ubiquitous pathogen that causes congenital infection and severe infections in immunocompromised patients. Chronic hCMV infection may also play an important role in immunosenescence and adverse health outcomes in older adults. THP-1, a human monocytic cell line and its derived macrophages serve as a useful cell culture model for mechanistic studies of hCMV infection and its underlying biology. A major methodological challenge is the lack of a quick and reliable tool to accurately determine the efficiency of hCMV infection in THP-1 derived macrophages. In this study, we developed a flow cytometry based method using commercially available monoclonal antibody (MAb) against hCMV immediate early (IE) antigen that can accurately determine infection efficiency. We used 0.5% formaldehyde for fixation, 90% methanol for permeabilization, and incubation with FITC conjugated MAb at 37°C. The method was tested by hCMV infection with laboratory Towne strain in the presence or absence of hydrocortisone. It was also compared with the routine flow cytometry protocol using Cytofix/Cytoperm solution and with immunofluorescence. The results indicate that this new method is reliable and time saving for accurate determination of infection efficiency. It may facilitate further investigations into the underlying biological mechanisms of hCMV infection. PMID:25958130

    A radiographic stereophotogrammetric technique (SPG) was used to evaluate quantitatively the presence of early femoral prosthesis subsidence after total hip arthroplasty (THA). This paper focuses on the measurement of subsidence in 12 patients who remained asymptomatic during the first two years after surgery. Only one of these had SPG estimated subsidence in excess of one millimeter at any timepoint. These findings are consistent with the conclusion that early postoperative subsidence is not a common finding among asymptomatic THA patients. PMID:6469528

    2010-05-01

    Rotavirus is a major cause of infectious intestinal disease in young children; a substantial prevalence of asymptomatic infection has been reported across all age groups. In this study, the authors determined characteristics of asymptomatic rotavirus infection and potential risk factors for infection. Healthy persons were recruited at random from the general population of England during the Study of Infectious Intestinal Disease in England (1993-1996). Rotavirus infection was identified using reverse-transcription polymerase chain reaction. Multivariable logistic regression was used to compare exposures reported by participants with rotavirus infection with those of participants who tested negative. Multiple imputation was used to account for missing responses in the data set. The age-adjusted prevalence of asymptomatic rotavirus infection was 11%; prevalence was highest in children under age 18 years. Attendance at day care was a risk factor for asymptomatic rotavirus infection in children under age 5 years; living in a household with a baby that was still in diapers was a risk factor in older adults. The results suggest that asymptomatic rotavirus infection is transmitted through the same route as rotavirus infectious intestinal disease: person-to-person contact. More work is needed to understand the role of asymptomatic infections in transmission leading to rotavirus disease. PMID:20392863

    Full Text Available Abstract Congenital pulmonary lymphangiectasia (PL is a rare developmental disorder involving the lung, and characterized by pulmonary subpleural, interlobar, perivascular and peribronchial lymphatic dilatation. The prevalence is unknown. PL presents at birth with severe respiratory distress, tachypnea and cyanosis, with a very high mortality rate at or within a few hours of birth. Most reported cases are sporadic and the etiology is not completely understood. It has been suggested that PL lymphatic channels of the fetal lung do not undergo the normal regression process at 20 weeks of gestation. Secondary PL may be caused by a cardiac lesion. The diagnostic approach includes complete family and obstetric history, conventional radiologic studies, ultrasound and magnetic resonance studies, lymphoscintigraphy, lung functionality tests, lung biopsy, bronchoscopy, and pleural effusion examination. During the prenatal period, all causes leading to hydrops fetalis should be considered in the diagnosis of PL. Fetal ultrasound evaluation plays a key role in the antenatal diagnosis of PL. At birth, mechanical ventilation and pleural drainage are nearly always necessary to obtain a favorable outcome of respiratory distress. Home supplemental oxygen therapy and symptomatic treatment of recurrent cough and wheeze are often necessary during childhood, sometimes associated with prolonged pleural drainage. Recent advances in intensive neonatal care have changed the previously nearly fatal outcome of PL at birth. Patients affected by PL who survive infancy, present medical problems which are characteristic of chronic lung disease.

    In this report, we describe the esophageal atresia in terms of current surgical management on the basis of our experience and literatures. Traditionally, infants with esophageal atresia have presented shortly after birth because of an inability to pass an orogastric tube, respiratory distress, or an inability to tolerate feeding. And also, an isolated trachea-esophageal fistula (TEF) usually cases coughing, recurrent pneumonia, or choking during feedings. To ignore these symptoms is to risk a delayed diagnosis. The condition may be associated with other major congenital anomalies such as those seen in the vertebral, anal, cardiac, tracheo-esophageal, renal/radial (VACTER) association, or it may be an isolated defect. Therapeutic strategies for esophageal atresia are a prevention of pulmonary complication by TEF closing and an early establishment of enteral alimentation. We promptly repair healthy infants without performing a gastrostomy and delay repair in infants with high-risk factors such as associated severe cardiac anomaly and respiratory insufficiency. Esophageal atresia has been classically approached through a thoracotomy. The disadvantages of such a thoracotomy have been recognized for a long time, for example winged scapula, elevation of fixation of shoulder, asymmetry of the chest wall, rib fusion, scoliosis, and breast and pectoral muscle maldevelopment. To avoid such disadvantages, thoracoscopic repair was recently reported. PMID:26197921

    Congenital renal parenchymal and pelvicalyceal abnormalities have a wide spectrum. Most of them are asymptomatic, like that of ectopia, cross fused kidney, horseshoe kidney, etc., while a few of them become complicated, leading to renal failure and death. It is very important for the radiologist to identify these anatomic variants and guide the clinicians for surgical and therapeutic procedures. Cross-sectional imaging with a volume rendered technique/maximum intensity projection has overcome ultrasonography and IVU for identification and interpretation of some of these variants.

    Pleuropulmonary blastoma (PPB) is an aggressive tumour accounting for less than 1% of all primary malignant lung tumours in the paediatric population. It can be associated with cystic pulmonary lesions, which may be evident at the time of diagnosis or predate the appearance of the tumour. There are contradictory reports about the value of prophylactic resection of pulmonary cysts in protecting patients from developing PPB. We report an individual case where asymptomatic congenital lobar emphysema was incidentally picked up on CXR. Following a period of surveillance the lesion was resected due to increasing size. The histology of the lesion revealed PPB Type I.

  18. Coil embolization of a congenital intrahepatic arterioportal fistula: increasing experience in management

    International Nuclear Information System (INIS)

    Congenital intrahepatic arterioportal fistula (IAPF) is a rare condition and there is limited experience of transcatheter embolization. We report here the transcatheter coil embolization of an incidentally found, asymptomatic congenital IAPF in a 16-month-old patient. After demonstrating that the IAPF was fed by two branches of a dilated left hepatic artery and drained into an aneurysm of the left portal vein, the feeding arteries were superselectively catheterized and occluded by microcoils in a single session. Follow-up was uneventful for 1 year. With respect to this and previously reported cases, we believe that embolization of feeding arteries is a safe and effective method that should be the primary choice of treatment; however, further cases should be reported to confirm this belief.

    Noroviruses (NoV) are the most common cause of epidemic gastroenteritis world-wide. NoV infections are often asymptomatic, although individuals still shed large amounts of NoV in their stool. Understanding the differences between asymptomatic and symptomatic individuals would help in elucidating mechanisms of NoV pathogenesis. Our goal was to compare the serum cytokine responses and faecal viral RNA titres of asymptomatic and symptomatic NoV-infected individuals. We tested serum samples from infected subjects (n = 26; 19 symptomatic, seven asymptomatic) from two human challenge studies of GI.1 NoV for 16 cytokines. Samples from prechallenge and days 1-4 post-challenge were tested for these cytokines. Cytokine levels were compared to stool NoV RNA titres quantified previously by reverse transcription-polymerase chain reaction (RT-qPCR). While both symptomatic and asymptomatic groups had similar patterns of cytokine responses, the symptomatic group generally exhibited a greater elevation of T helper type 1 (Th1) and Th2 cytokines and IL-8 post-challenge compared to the asymptomatic group (all P viral RNA titre was associated positively with daily IL-6 concentration and negatively with daily IL-12p40 concentration (all P viral RNA titre, duration of viral shedding or cumulative shedding. Symptomatic individuals, compared to asymptomatic, have greater immune system activation, as measured by serum cytokines, but they do not have greater viral burden, as measured by titre and shedding, suggesting that symptoms may be immune-mediated in NoV infection.

    Cytomegalovirus (CMV) infections occur worldwide and primary infection usually occurs in early childhood and is often asymptomatic whereas primary infection in adults may result in symptomatic illness. CMV establishes a chronic latent infection with intermittent periods of reactivation. Primary infection or reactivation associate with increased mortality and morbidity in those who are immunocompromised. Transplacental transmission may result in significant birth defects or long-term sensorineural hearing loss.We performed a study to determine the CMV seroprevalence and the association between HLA Class I alleles and frequency of CMV infection in Ireland. The presence of CMV IgG, a marker of previous CMV infection, was determined for a cohort of 1849 HLA typed solid organ transplant donors between 1990 and 2013. The presence of CMV IgG was correlated with HLA type.The CMV seroprevalence in solid organ transplant donors was 33.4% (range 22-48% per annum) over the time period 1990 to 2013. Multivariate logistic regression analysis showed that both age and HLA alleles were associated with CMV seropositivity. A significant and positive relationship between age and CMV seropositivity was observed (OR = 1.013, P HLA-A1, HLA-A2, and HLA-A3 in our cohort were 40.8%, 48.8%, and 25.9%, respectively. Logistic regression analysis showed that the presence of HLA-A1 but not HLA-A2 or HLA-A3 was independently associated with CMV seronegativity (P HLA-A2 and HLA-A3 alleles were significantly more likely to be CMV seropositive (P HLA-B5, HLA-B7, and HLA-B8 in our cohort were 6.1%, 31.2%, and 30.8%, respectively. The presence of the most common inherited haplotype in the Irish population, HLA-A1, B8 was significantly associated with CMV seronegativity (OR = 1.278, P HLA-A1 in the Irish population may, in part, have a role in the reduced susceptibility to CMV infection.

    The deficiency in factor I or fibrinogen is a largely unknown genetic disease. It is a rare condition inherited as an autosomal recessive, whose clinical events are variable, ranging from moderate to minimal bleeding or cataclysmic hemorrhage. We report a case of congenital afibrinogenemia in a 17 years-old patient hospitalized in surgical ICU for hemoperitoneum medium abundance discovered by abdominal ultrasound performed before a picture of abdominopelvic pain lasting for 24 hours. Exploration led to the diagnosis of congenital afibrinogenemia with favorable evolution with a contribution of factor deficient. Through this case we raise the problem of congenital afibrinogenemia in diagnosis and the peculiarities of its management. PMID:20870582

    Asymptomatic bacteriuria is one of the most common and important bacterial infections during pregnancy and can result in progressive infections and endanger maternal as well as fetal health. In this study, we assessed the relationship between asymptomatic bacteriuria and pre-eclampsia. In this case-control study, pregnant women who presented to Imam Reza Hospital in Kermanshah in 2013-14 were studied. The minimum sample size was calculated as 125 pregnant women in each group with a total of 250 subjects. There were 125 women with pre-eclampsia and 125 women without pre-eclampsia (control group). Matching was done for age, gestational age, and parity between case and control groups. Matching was verified by a P value of 0.061 for maternal age and gestational age and 0.77 for parity. The statistical analyses were done by applying the chi-squared test and determining odds ratio (OR) for having bacteriuria in univariate logistic regression as well as multivariate regression with adjusting the effect of maternal age, gestational age, and parity. Pyuria and bacteriuria were significantly more common in pre-eclampsia group than in control group. The results showed that a significant association existed between asymptomatic bacteriuria and pre-eclampsia. The rate of asymptomatic bacteriuria was 6.8 times higher in women with pre-eclampsia compared to those without pre-eclampsia. Further studies are required for better clarification of association between asymptomatic bacteriuria and pre-eclampsia. PMID:26925912

    Symptomatic and asymptomatic bacteriuria is common in pregnant women. A history of previous urinary tract infections and low socioeconomic status are risk factors for bacteriuria in pregnancy. Escherichia coli is the most common aetiologic agent in both symptomatic and asymptomatic infection and quantitative culture is the gold standard for diagnosis. Treatment of asymptomatic bacteriuria has been shown to reduce the rate of pyelonephritis in pregnancy and therefore screening for and treatment of asymptomatic bacteriuria has become a standard of obstetrical care. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of low birth weight, but the methodological quality of the studies limits the strength of the conclusions that can be drawn. Debate exists in the literature as to whether treated pyelonephritis is associated with adverse fetal outcomes. There is no clear consensus in the literature on antibiotic choice or duration of therapy for infection. With increasing antibiotic resistance, consideration of local resistance rates is necessary when choosing therapy. PMID:18826482

  9. Asymptomatic severe aortic stenosis: challenges in diagnosis and management.

    Optimal management for asymptomatic severe aortic stenosis (AS) remains controversial. Considering the increase in elderly patients, improved surgical outcomes and the introduction of transcatheter aortic valve implantation, we must reconsider the optimal management of asymptomatic severe AS. In this article, previous studies regarding the natural history of asymptomatic severe AS were reviewed to obtain a clinical perspective of AS in the growing elderly patient population. The incidence of sudden death in asymptomatic severe AS varies among studies from 0.25% to 1.7% per year, with differences related to study design and patient background. Except for very severe AS, sudden death or AS-related cardiac death without preceding symptoms is uncommon if 'watchful' waiting strategy is possible. Therefore, early operation is reasonable in very severe AS, but it is not recommended for all patients with severe AS. Using exercise tests, plasma levels of natriuretic peptides and other parameters, risk stratification of asymptomatic severe AS is needed to select patients who may have greater benefit following early operation. On the other hand, 'watchful' waiting is not always possible in real world of our practice. Patient education and periodic echocardiography are essential in 'watchful' waiting, which is not simply waiting strategy without careful monitoring. Individualised discussion regarding the indication for early operation is necessary, considering age, clinical background, predicted natural history and operative risk in each patient. PMID:27091844

    The complete genome of the English isolate of rat cytomegalovirus (RCMV-E) was determined. RCMV-E has a 202,946-bp genome with noninverting repeats but without terminal repeats. Thus, it differs significantly in size and genomic arrangement from closely related rodent cytomegaloviruses (CMVs). To account for the differences between the rat CMV isolates of Maastricht and England, RCMV-E was classified as Murid herpesvirus 8 by the International Committee on Taxonomy of Viruses.

    The clinical and pathologic features of congenital granular-cell myoblastoma in five infant girls are reported. One lesion, treated expectantly, progressively decreased in size and after 3 yr and 9 mo could not be detected, while two lesions which were imcompletely excised did not recur. It is suggested that congenital granular-cell myoblastoma is caused by an intrauterine stimulus, and that this stimulus may possible be production of estrogen by the fetus. Congential granular-cell myoblastoma should be treated expectantly or by limited excision, and has an excellent prognosis. PMID:164527

    We present the MRI features of a congenital urethroperineal fistula diagnosed in a 12-year-old boy being evaluated after a single urinary tract infection. This diagnosis was initially suggested by voiding cystourethrogram and confirmed by MRI. Imaging revealed an abnormal fluid-filled tract arising from the posterior urethra and tracking to the perineal skin surface that increased in size during micturition. Surgical resection and histopathological evaluation of the abnormal tract confirmed the diagnosis of congenital urethroperineal fistula. MRI played important roles in confirming the diagnosis and assisting surgical planning. (orig.)

    Full Text Available Congenital syphilis (CS is mainly a consequence of the lack of antenatal care and control of sexually transmitted infections.The bedrock of the prevention of CS is syphilis diagnosis by serological screening during pregnancy.Current Italian guidelines suggest that all the pregnant women should be tested in the first trimester. Due to the frequently absence of specific signs of infection at birth, laboratory tests are often the only method for a correct CS diagnosis. The aim of this study was to evaluate the usefulness of Treponema pallidum IgM Western Blot (WB and Polymerase Chain Reaction (PCR on cerebrospinal fluid (CSF as an aid in the diagnosis of CS during a prospective surveillance study carried out at St. Orsola Hospital in Bologna, Italy, from November 2000 through June 2010. All pregnant women during pregnancy and at delivery were screened for syphilis by ARCHITECT® Syphilis TP, Abbott. Positive samples were further analysed by Treponema Pallidum Hemagglutination Test (TPHA and Rapid Plasma Reagin (RPR tests, Radim.An in-house Western Blot (WB was also performed. Infants born to syphilis seropositive mothers were enrolled in a prospective follow up. At birth, tests were performed (including IgM WB. Infants with positive RPR tests at birth born to mothers not adequately treated received also a long bone radiograph as well as a complete CSF analysis, including Veneral Disease Research Laboratori (VDRL (Siemens Healthcare Diagnostics and PCR testing. All seroreactive infants received careful follow up examinations and serological testing at 0, 3, 6, 9, 12 months or until the tests became negative. In this study, positive syphilis serology was noted in 151 pregnant women delivering in our hospital. Fifteen women had never been adequately treated, and 9 out 15 gave birth to infected newborns.All these 9 infants had positive IgM WB results on serum samples. Two babies had characteristic long bone lesions at X-ray examination and 3 were born

    Full Text Available Even though Silicone injection for breast augmentation has been related to disastrous long-term effects and complications, some patients do not develop significant symptoms at all (asymptomatic. Unfortunately, the management of asymptomatic Silicone-injected breast is still unclear and has never been reported exclusively. We present two cases of asymptomatic patients with a history of liquid Silicone injections who refused to have a mastectomy. They were concerned with the breast ptosis and chose to undergo reduction mammoplasty to improve the appearance of the breasts. Magnetic resonance imaging may be useful as an additional screening tool to confirm the diagnosis and exclude the presence of malignancy in breasts with injected Silicone. We believe that breast reduction may be the alternative option for women with a history of liquid Silicone injection who have no symptoms but desire to preserve their breasts and improve their aesthetics.

    Full Text Available Asymptomatic bacteriuria is prevalent during pregnancy. It can lead to pyelonephritis, premature pregnancy and low birth weight. In this prospective study, to determine prevalence and risk factors of asymptomatic bacteriuria, 205 consecutive pregnant women who visited our prenatal care clinic in Mirza-Koochakkhan Hospital and had no urinary symptom were entered. Patients data were recorded using a questionnaire and urine samples were obtained for urinalysis and urine culture. We analysed data by using fisher exact and chi-squared test. 14 cases had positive urine culture (6.8%. Significant correlation was seen between asymptomatic bacteriuria and age, parity, past history of kidney stone, pyelonephritis, urinary tract infection, preterm delivery and pyuria pvalue <0.05. We suggest routine urine culture in first visit of high risk and 16th week of low risk pregnancies.

    The aim of the study was to identify the frequency of asymptomatic brain metastases detected by computed tomography (CT) scans in patients with metastatic cutaneous melanoma referred to first-line systemic treatment. Between 1995 and 2009, 697 Danish patients were screened with a contrast......-enhanced CT scan of the brain before the start of interleukin-2 (IL-2)-based immunotherapy. Among the 697 patients, 80 had asymptomatic brain metastases (12%). Patients' characteristics did not differ significantly between groups with and without brain metastases. Patients received systemic treatment (IL-2......-based or cytotoxic chemotherapy), local treatment (stereotactic radiotherapy, whole-brain radiotherapy or surgery), or best supportive care only. The survival was significantly shorter for patients with asymptomatic brain metastases compared with patients without brain metastases (P...

    Even though Silicone injection for breast augmentation has been related to disastrous long-term effects and complications, some patients do not develop significant symptoms at all (asymptomatic). Unfortunately, the management of asymptomatic Silicone-injected breast is still unclear and has never been reported exclusively. We present two cases of asymptomatic patients with a history of liquid Silicone injections who refused to have a mastectomy. They were concerned with the breast ptosis and chose to undergo reduction mammoplasty to improve the appearance of the breasts. Magnetic resonance imaging may be useful as an additional screening tool to confirm the diagnosis and exclude the presence of malignancy in breasts with injected Silicone. We believe that breast reduction may be the alternative option for women with a history of liquid Silicone injection who have no symptoms but desire to preserve their breasts and improve their aesthetics.

    Cytomegalovirus(CMV) is a common virus in patients with ulcerative colitis receiving immunosuppressive drugs. Many studies suggested that CMV infection is an exacerbating factor in patients with ulcerative colitis. The role of CMV in exacerbations of ulcerative colitis has been discussed. One of studies starting this discussion is an article entitled "CMV positive ulcerative colitis: A single center experience and literature review" by Kopylov et al. However, we think that there are some points that should be emphasized about the study. Especially, the small number of patients in the study has led to meaningless results. Large controlled prospective trials are needed to clarify the benefit of antiviral therapy for active ulcerative colitis patients.

    Cytomegalovirus (CMV) continues to be a leading cause of morbidity and mortality in transplant recipients, despite major advancements in preventative strategies. Antiviral prophylaxis and pre-emptive antiviral therapeutic regimens are associated with a high incidence of late-onset end-organ disease and cause drug-related toxicity when overused. Therefore, the identification of risk factors for CMV replication is required. Genetic and immunological factors that predispose individuals to CMV-related clinical complications have been identified and may be instrumental for optimizing CMV treatment in the future. Evidence suggests a causal pathogenetic link between CMV-related complications and inflammatory diseases in non-canonically immunosuppressed individuals such as patients with lung injury and critically ill and cancer patients. However, a randomized clinical trial is required to determine if a causal relationship exists. J. Med. Virol. 88:1103-1112, 2016. © 2015 Wiley Periodicals, Inc. PMID:26681168

    Cytomegalovirus (CMV) colitis is uncommon in immunocompetent patients, despite a high seroprevalence rate of CMV in the general population. CMV infection has been described in individuals with compromised immune systems: in AIDS, under corticosteroid and immune modulating treatment, with cancer or haematological malignancies. Its most frequent clinical presentation is a necrotising ulcerative form; pseudotumoural CMV colitis has been described as highly exceptional. We report a case of CMV colitis mimicking rectal carcinoma in an immunocompetent elderly woman. The immunosenescence and protein-energy malnutrition increase incidence and severity of infectious diseases in elderly individuals. Immunosenescence may affect all aspects of immunity; severe protein malnutrition modifies mostly cellular immunity, growing susceptibility to infections. PMID:27166009

    Full Text Available Background: Psychiatric morbidity in human immunodeficiency virus (HIV patients is being studied all over the world. There is paucity of Indian literature particularly in asymptomatic HIV individuals. Aim: The aim of the following study is to establish the prevalence and the determinants of psychiatric morbidity in asymptomatic HIV patients. Materials and Methods: A cross-sectional study was undertaken to assess psychiatric morbidity as per ICD-10 dacryocystorhinostomy criteria in 100 consecutive asymptomatic seropositive HIV patients and an equal number of age, sex, education, economic and marital status matched HIV seronegative control. All subjects were assessed with the general health questionnaire (GHQ, mini mental status examination, hospital anxiety and depression scale (HADS and sensation seeking scale (SSS and the scores were analyzed statistically. Results: Asymptomatic HIV positive patients had significantly higher GHQ caseness and depression but not anxiety on HADS as compared to HIV seronegative controls. On SSS asymptomatic HIV seropositive subjects showed significant higher scores in thrill and adventure seeking, experience seeking and boredom susceptibility as compared to controls. HIV seropositive patients had significantly higher incidence of total psychiatric morbidity. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. Conclusion: Psychiatric morbidity is higher in asymptomatic HIV patients when compared to HIV seronegative controls. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. High sensation seeking and substance abuse found in HIV seropositive patients may play a vital role in engaging in high-risk behavior resulting in this dreaded illness.

    Aortic stenosis (AS) is a disease that progresses slowly for years without symptoms, so patients need to be carefully managed with appropriate follow up and referred for aortic valve replacement in a timely manner. Development of symptoms is a clear indication for aortic valve intervention in patients with severe AS. The decision for early surgery in patients with asymptomatic severe AS is more complex. In this review, we discuss how to identify high-risk patients with asymptomatic severe AS who may benefit from early surgery. PMID:26981214

    Since the introduction of cardiac surgery, the prospects for children born with a cardiac defect have improved spectacularly. Many reach adulthood and the population of adults with congenital heart disease is increasing and ageing. However, repair of congenital heart disease does not mean cure. Many adults with congenital heart disease encounter late complications. Late morbidity can be related to the congenital heart defect itself, but may also be the consequence of the surgical or medical treatment or longstanding alterations in hemodynamics, neurodevelopment and psychosocial development. This narrative review describes the cardiac and non-cardiac long-term morbidity in the adult population with congenital heart disease. PMID:27451323

    2011-10-01

    Full Text Available INTRODUCTION: Human cytomegalovirus is an opportunistic betaherpesvirus that causes persistent and serious infections in immunodeficient patients. Recurrent infections occur due to the presence of the virus in a latent state in some cell types. It is possible to examine the virus using molecular methods to aid in the immunological diagnosis and to generate a molecular viral profile in immunodeficient patients. The objective of this study was to characterize cytomegalovirus genotypes and to generate the epidemiological and molecular viral profile in immunodeficient patients. METHODS: A total of 105 samples were collected from immunodeficient patients from the City of Belém, including newborns, hemodialysis patients, transplant recipients and HIV+ patients. An IgG and IgM antibody study was completed using ELISA, and enzymatic analysis by restriction fragment length polymorphism (RFLP was performed to characterize viral genotypes. RESULTS: It was observed that 100% of the patients had IgG antibodies, 87% of which were IgG+/IgM-, consistent with a prior infection profile, 13% were IgG+/IgM+, suggestive of recent infection. The newborn group had the highest frequency (27% of the IgG+/IgM+ profile. By RFLP analysis, only one genotype was observed, gB2, which corresponded to the standard AD169 strain. CONCLUSIONS: The presence of IgM antibodies in new borns indicates that HCMV continues to be an important cause of congenital infection. The low observed genotypic diversity could be attributed to the small sample size because newborns were excluded from the RFLP analysis. This study will be continued including samples from newborns to extend the knowledge of the general and molecular epidemiology of HCMV in immunodeficient patients.

    Congenital dacryocystocele can be diagnosed prenatally by imaging. Prenatal MRI is increasingly utilized for fetal diagnosis. To present the radiological and clinical features of seven fetuses with congenital dacryocystocele diagnosed with prenatal MRI. The institutional database of 1,028 consecutive prenatal MR examinations performed during a period of 4 years was reviewed retrospectively. The cases of congenital dacryocystocele were identified by reading the report of each MRI study. The incidence of dacryocystocele diagnosed with prenatal MRI was 0.7% (n=7/1,028). The dacryocystocele was bilateral in three fetuses. Mean gestational age at the time of diagnosis was 31 weeks. The indication for prenatal MRI was the presence or the suspicion of central nervous system abnormality in six fetuses and diaphragmatic hernia in one. Dacryocystocele was associated with an intranasal cyst in six of ten eyes. Prenatal sonography revealed dacryocystocele in only two of seven fetuses. Of eight eyes with postnatal follow-up, four did not have any lacrimal symptoms. Prenatal MRI can delineate congenital dacryocystocele more clearly and in a more detailed fashion than ultrasonography. Presence of dacryocystocele was symptomatic in only 50% of our patients, supporting that prenatal diagnosis of dacryocystocele might follow a benign course. (orig.)

    Full Text Available Congenital infection with Trypanosoma cruzi is a global problem, occurring on average in 5% of children born from chronically infected mothers in endemic areas, with variations depending on the region. This presentation aims to focus on and update epidemiological data, research methods, involved factors, control strategy and possible prevention of congenital infection with T. cruzi. Considering that etiological treatment of the child is always effective if performed before one year of age, the diagnosis of infection in pregnant women and their newborns has to become the standard of care and integrated into the surveillance programs of syphilis and human immunodeficiency virus. In addition to the standard tests, polymerase chain reaction performed on blood of neonates of infected mothers one month after birth might improve the diagnosis of congenital infection. Recent data bring out that its transmission can be prevented through treatment of infected women before they become pregnant. The role of parasite genotypes and host genetic factors in parasite transmission and development of infection in foetuses/neonates has to be more investigated in order to better estimate the risk factors and impact on health of congenital infection with T. cruzi.

    To investigate whether asymptomatic cytomegalovirus (CMV) viraemia impact the course of human immunodeficiency virus (HIV) infection, this study evaluated the effect of CMV replication on progression of newly-diagnosed HIV infected individuals towards AIDS events and death. In a 3-year prospective study on co-infected patients, clinical, immunological, and virological tests were performed in a national reference hospital quarterly. CMV viraemia was quantified by RoboGene® HCMV DNA Quantification Kit (Analytik Jena, Germany), on ABI Prism® 7000 Sequence Detection System (Applied Biosystems, USA). One hundred and five patients were enrolled with a balanced sex distribution and a median age of 30.7 years. Median CD4(+) cell count at enrollment was 164/mm(3) and median HIV RNA 4.6 log10 copies/ml. Detectable CMV viraemia was found in 25.7% of the patients. Kaplan-Meier analysis showed progression of HIV infection to be significantly increased in those with active CMV replication and/or low CD4(+) cell count. Cox regression indicated the risk of developing new AIDS events was 2.6 times greater in patients with detectable CMV viraemia versus those without (CI95% 1-6.6; P = 0.04). Also in multivariate analysis, the overall risk of progression to AIDS events or death was 3-fold higher in those with detectable CMV viraemia (CI95% 1.3-6.7; P = 0.008) and 2.3-fold higher if CD4(+) cell count was below 100/mm(3) (CI95% 1-5.1; P = 0.04). In these young Romanian HIV-seropositives, active CMV replication increased morbidity, even when treated with combination antiretroviral therapy. Further studies are needed to evaluate if serial quantitative CMV-DNA levels might correlate with non-infectious inflammation-related risks in patients with HIV and active CMV infection.

    Quantitative characterization of carotid atherosclerosis and classification into symptomatic or asymptomatic type is crucial in both diagnosis and treatment planning. This paper describes a computer-aided diagnosis (CAD) system which analyzes ultrasound images and classifies them into symptomatic and asymptomatic based on the textural features. The proposed CAD system consists of three modules. The first module is preprocessing, which conditions the images for the subsequent feature extraction. The feature extraction stage uses image texture analysis to calculate Standard deviation, Entropy, Symmetry, and Run Percentage. Finally, classification is performed using AdaBoost and Support Vector Machine for automated decision making. For Adaboost, we compared the performance of five distinct configurations (Least Squares, Maximum- Likelihood, Normal Density Discriminant Function, Pocket, and Stumps) of this algorithm. For Support Vector Machine, we compared the performance using five different configurations (linear kernel, polynomial kernel configurations of different orders and radial basis function kernels). SVM with radial basis function kernel for support vector machine presented the best classification result: classification accuracy of 82.4%, sensitivity of 82.9%, and specificity of 82.1%. We feel that texture features coupled with the Support Vector Machine classifier can be used to identify the plaque tissue type. An Integrated Index, called symptomatic asymptomatic carotid index (SACI), is proposed using texture features to discriminate symptomatic and asymptomatic carotid ultrasound images using just one index or number. We hope this SACI can be used as an adjunct tool by the vascular surgeons for daily screening. PMID:21243411

    Parasitic diseases suppose an important health problem in people from high endemic areas, so these must be discarded properly. Usually, these infections develop asymptomatically but, in propitious situations, are likely to reactivate themselves and can cause clinical symptoms and/or complications in the receiving country. Moreover, in some cases it is possible local transmission. Early diagnosis of these parasitic diseases made by appropriate parasitological techniques and its specific treatment will benefit both, the individual and the community. These techniques must be selected according to geoepidemiological criteria, patient's origin, migration route or time spent outside the endemic area; but other factors must also be considered as its sensitivity and specificity, implementation experience and availability. Given the high prevalence of intestinal parasites on asymptomatic immigrants, it is recommended to conduct a study by coproparasitological techniques. Because of its potential severity, the screening of asymptomatic malaria with sensitive techniques such as PCR (polymerase chain reaction) is also advisable. Serological screening for Chagas disease should be performed on all Latin American immigrants, except for people from the Caribbean islands. Other important parasites, which should be excluded, are filariasis and urinary schistosomiasis, by using microscopic examination. The aim of this paper is to review the different techniques for the screening of parasitic diseases and its advices within the care protocols for asymptomatic immigrants. PMID:27474244

    The detection of lesions of the paranasal sinuses as incidental findings during magnetic resonance imaging of patients suspected of intracranial disease who have no nasal symptoms has been far more common than we expected. The present study was performed on 325 patients with a mean age of 60.7 years. Medical histories were taken whether they had any nasal symptoms or not. Asymptomatic sinus disease was present in 41.6% of the 257 patients who had no nasal symptoms, and 9.7% of the patients had either marked mucosal thickening, excessive fluid or polyps in the maxillary sinuses. Although the mean age of these patients was comparatively high, we can infer that 1 in 10 have relatively severe sinus lesions. Mucociliary transport time was measured using the saccharin method in 15 patients who had sinus disease but no nasal symptoms. The mean transport time was 15.6 minutes and within normal limits. Routine ENT examination revealed no lesions in the nasal cavity of any of the subjects. We classified the patients with asymptomatic sinus disease into two groups -- group A: patients with sinus disease associated with some nasal manifestations but who did not complain about them, and group B: patients who had sinus disease but did not have any nasal problems. Group B represents genuine asymptomatic sinus disease in the narrow sense. Most asymptomatic patients in this study appeared to belong to group B. They had some sinus disease, but because their mucociliary function in their nasal cavity was normal, they did not have any nasal symptoms. When we find patients with asymptomatic sinus disease, we have to determine which group they belong to by examining their nasal cavity and measuring their saccharin time. Patients in group A should be medically treated, but those in group B should be followed without medical treatment. (author).

Mucociliary transport time was measured using the saccharin method in 15 patients who had sinus disease but no nasal symptoms. The mean transport time was 15.6 minutes and within normal limits. Routine ENT examination revealed no lesions in the nasal cavity of any of the subjects. We classified the patients with asymptomatic sinus disease into two groups -- group A: patients with sinus disease associated with some nasal manifestations but who did not complain about them, and group B: patients who had sinus disease but did not have any nasal problems. Group B represents genuine asymptomatic sinus disease in the narrow sense. Most asymptomatic patients in this study appeared to belong to group B. They had some sinus disease, but because their mucociliary function in their nasal cavity was normal, they did not have any nasal symptoms. When we find patients with asymptomatic sinus disease, we have to determine which group they belong to by examining their nasal cavity and measuring their saccharin time. Patients in group A should be medically treated, but those in group B should be followed without medical treatment. (author)

    Full Text Available BACKGROUND: Congenital hypothyroidism (CH often seems to be associated with other congenital abnormalities, mostly cardiac in nature. The aim of this study was to determine the prevalence of cardiac malformations in patients with CH diagnosed during CH screening program in Isfahan. METHODS: In this cross-sectional study, cardiac malformations were determined in CH patients were compared to controls using echocardiography. The association between cardiac malformations and mean T4 and TSH concentrations, etiology of CH according to radiologic findings and permanent and transient CH were studied in CH patients. RESULTS: Overall, 96 and 59 subjects were included in the case and control groups, respectively. Cardiac malformations were present in 30.2% (n = 29 and 15.2% (n = 9 of case and control groups, respectively; i.e. a higher prevalence in CH patients than in controls (P = 0.03. The prevalence of cardiac malformations without patent foramen oval was 6.25% (n = 6 in CH patients and 1.7% (n = 1 in control group (P = 0.1. There was no significant association between the presence of cardiac malformations and the aforementioned variables. CONCLUSIONS: High prevalence of cardiac malformations in CH patients strongly suggests the potential involvement of genetic factors in the pathogenesis of CH. This emphasizes on the necessity of genetic studies involving CH patients. KEY WORDS: Congenital hypothyroidism, cardiac malformations, genetics.

    Cytomegalovirus (CMV) is the leading cause of congenital infection and non-genetic sensorineural hearing loss in children. There are no recent data on the incidence of CMV infection during pregnancy in Canada. This present study was undertaken to determine the seroprevalence of CMV IgG antibodies and the rate of seroconversion in a cohort of pregnant women in the province of Québec, Canada. We used serum samples and questionnaire data collected as part of the 3D Pregnancy and Birth Cohort Study (2010-2013) conducted in Québec, Canada. CMV IgG antibodies were determined in serum samples collected at the first and third trimesters. Associations between independent variables and seroprevalence were assessed using logistic regression, and associations with seroconversions, by Poisson regression. Of 1938 pregnant women tested, 40·4% were seropositive for CMV at baseline. Previous CMV infection was associated with: working as a daycare educator, lower education, lower income, having had children, first language other than French or English, and being born outside Canada or the United States. Of the 1122 initially seronegative women, 24 (2·1%) seroconverted between their first and third trimesters. The seroconversion rate was 1·4 [95% confidence interval (CI) 0·9-2·1]/10 000 person-days at risk or 3·9 (95% CI 2·5-5·9)/100 pregnancies (assuming a 280-day gestation). The high proportion of pregnant women susceptible to CMV infection (nearly 60%) and the subsequent rate of seroconversion are of concern. PMID:26686548

    Full Text Available Dante P Melendez,1,2 Raymund R Razonable1,2 1Division of Infectious Diseases, 2William J von Liebig Center for Transplantation and Clinical Regeneration, Mayo Clinic, Rochester, MN, USA Abstract: Infection with cytomegalovirus is prevalent in immunosuppressed patients. In solid organ transplant and hematopoietic stem cell transplant recipients, cytomegalovirus infection is associated with high morbidity and preventable mortality. Prevention and treatment of cytomegalovirus with currently approved antiviral drugs is often associated with side effects that sometimes preclude their use. Moreover, cytomegalovirus has developed mutations that confer resistance to standard antiviral drugs. During the last decade, there have been calls to develop novel antiviral drugs that could provide better options for prevention and treatment of cytomegalovirus. Letermovir (AIC246 is a highly specific antiviral drug that is currently undergoing clinical development for the management of cytomegalovirus infection. It acts by inhibiting the viral terminase complex. Letermovir is highly potent in vitro and in vivo against cytomegalovirus. Because of a distinct mechanism of action, it does not exhibit cross-resistance with other antiviral drugs. It is predicted to be active against strains that are resistant to ganciclovir, foscarnet, and cidofovir. To date, early-phase clinical trials suggest a very low incidence of adverse effects. Herein, we present a comprehensive review on letermovir, from its postulated novel mechanism of action to the results of most recent clinical studies.

    Background.  Cytomegalovirus (CMV) is a major cause of morbidity and mortality in immunocompromised patients, with CMV pneumonitis among the most severe manifestations of infection. Although bronchoalveolar lavage (BAL) samples are frequently tested for CMV, the clinical utility of such testing remains uncertain. Methods.  Retrospective analysis of adult patients undergoing BAL testing via CMV polymerase chain reaction (PCR), shell vial culture, and conventional viral culture between August 2008 and May 2011 was performed. Cytomegalovirus diagnostic methods were compared with a comprehensive definition of CMV pneumonitis that takes into account signs and symptoms, underlying host immunodeficiency, radiographic findings, and laboratory results. Results.  Seven hundred five patients underwent 1077 bronchoscopy episodes with 1090 BAL specimens sent for CMV testing. Cytomegalovirus-positive patients were more likely to be hematopoietic cell transplant recipients (26% vs 8%, P comprehensive definition, the sensitivity and specificity of PCR, shell vial culture, and conventional culture were 91.3% and 94.6%, 54.4% and 97.4%, and 28.3% and 96.5%, respectively. Compared with culture, PCR provided significantly higher sensitivity and negative predictive value (P ≤ .001), without significantly lower positive predictive value. Cytomegalovirus quantitation did not improve test performance, resulting in a receiver operating characteristic curve with an area under the curve of 0.53. Conclusions.  Cytomegalovirus PCR combined with a comprehensive clinical definition provides a pragmatic approach for the diagnosis of CMV pneumonitis. PMID:26885542

    Full Text Available Abstract Introduction Cytomegalovirus-associated thrombosis has rarely been reported in the medical literature, and if so, mainly in immunocompromized patients. Case presentation We report the case of a 36-year-old Caucasian woman with acute cytomegalovirus infection presenting with spontaneous splenic infarcts. Trans-esophageal echocardiography did not show any vegetations or mural thrombi. The patient was also found to be heterozygous for the Factor V Leiden mutation. Anticoagulation treatment was considered but ruled out since cytomegalovirus was the obvious trigger for thrombosis in this patient. To the best of our knowledge, this is only the third report to date of cytomegalovirus-associated splenic infarcts. Conclusion This case report serves as additional evidence for the role of cytomegalovirus in thrombosis.

    Full Text Available Abstract Introduction Cytomegalovirus is a common virus responsible for a wide range of clinical manifestations. Hemolysis is a rare but potentially life-threatening complication of cytomegalovirus infection, described mostly in immunocompromised patients, the pathogenesis of which is still unclear. We performed a review of the literature regarding cases of hemolytic anemia during acute cytomegalovirus infection in apparently immunocompetent individuals. We searched for relevant articles in PubMed for the period of 1980 through 2008. Case presentation We describe a case of Coombs-negative hemolytic anemia in a 44-year-old Caucasian immunocompetent man with acute cytomegalovirus infection. Conclusion Clinicians should consider cytomegalovirus infection in the differential diagnosis of hemolytic anemia in immunocompetent adults. Possible therapeutic options include antiviral therapy and steroids, although the best treatment strategy is still controversial.

    Full Text Available The endoscopic finding of ileal ulcers, alone or in small number, is not usual, but when it occurs in asymptomatic patients, an impasse may be generated regarding the action to be taken, since the medical literature is unclear as to how to proceed in this situation. OBJECTIVE: Evaluate patients with ileal ulcers, single or in a small number, asymptomatic, and their follow-up. METHODS: The author reports a series of asymptomatic cases (23 patients of ulcers - single or in small number - found in colonoscopy exams performed for other reasons than typical clinical manifestations of Crohn's disease. RESULTS: Most patients were not treated and remained asymptomatic during the follow-up period. CONCLUSIONS: The patients remained asymptomatic and without treatment in most cases, and, considering the small number of cases and the short observation time, this study does not allow to conclude that this is the best practice in case of asymptomatic patients with ileal ulcer.O achado endoscópico de úlceras ileais, isoladas ou em pequeno número, não é frequente, mas quando ocorre em pacientes assintomáticos pode gerar um impasse quanto à conduta a ser tomada, já que a literatura médica não é clara quanto a como se proceder nessa situação.

  12. Asymptomatic pons tuberculoma in an infant with miliary tuberculosis

    International Nuclear Information System (INIS)

    Miliary tuberculosis is caused by the hematogenous spread of Mycobacterium tuberculosis and consists of 1.5% of all tuberculosis cases. It is seen mostly in infants because of the immature immune system, and central nervous system CNS involvement is not rare. Tuberculomas are rarely seen in the localized form of CNS tuberculosis, and only 4% are localized in the brain stem. We report a 4.5-month-old infant who deteriorated during follow-up with the diagnosis of cytomegalovirus pneumonia, and afterwards received the diagnosis of miliary tuberculosis. Although the baby had no neurologic abnormality and cerebrospinal fluid findings were normal, cranial MRI revealed contrast enhanced nodular lesions in pons, cerebellum, and right parietal region. The case is presented to intensify the importance of CNS investigation even if the patient with miliary tuberculosis has no neurologic finding. (author)

  13. Glucocorticoids facilitate the transcription from the human cytomegalovirus major immediate early promoter in glucocorticoid receptor- and nuclear factor-I-like protein-dependent manner

    International Nuclear Information System (INIS)

    Human cytomegalovirus (HCMV) is a common and usually asymptomatic virus agent in healthy individuals. Initiation of HCMV productive infection depends on expression of the major immediate early (MIE) genes. The transcription of HCMV MIE genes is regulated by a diverse set of transcription factors. It was previously reported that productive HCMV infection is triggered probably by elevation of the plasma hydroxycorticoid level. However, it is poorly understood whether the transcription of MIE genes is directly regulated by glucocorticoid. Here, we found that the dexamethasone (DEX), a synthetic glucocorticoid, facilitates the transcription of HCMV MIE genes through the MIE promoter and enhancer in a glucocorticoid receptor (GR)-dependent manner. By competitive EMSA and reporter assays, we revealed that an NF-I like protein is involved in DEX-mediated transcriptional activation of the MIE promoter. Thus, this study supports a notion that the increased level of hydroxycorticoid in the third trimester of pregnancy reactivates HCMV virus production from the latent state. - Highlights: • DEX facilitates the transcription from the HCMV MIE promoter. • GR is involved in DEX-dependent transcription from the HCMV MIE promoter. • A 17 bp repeat is responsible for the HCMV MIE promoter activation by DEX. • An NF-I-like protein is involved in the HCMV MIE promoter activation by DEX

    1984-12-01

    A cytomegalovirus (CMV)-specific sandwich hybridization test was constructed by using two adjacent BamHI DNA fragments of CMV DNA as reagents. The fragments were cloned into two different vectors. One of the recombinants was attached to the filter, and the other was the labeled probe. When present in the sample, CMV DNA mediated labeling of the filter by hybridizing to both the filter-bound DNA and the probe. The sandwich hybridization test was applied for the detection of CMV DNA from urine. DNA was released from virus by 2% Sarkosyl, concentrated by 2-butanol extraction and isopropanol precipitation, denatured, and finally subjected to the sandwich hybridization test. As a result, 70 to 90% of the original viral DNA could be recovered and demonstrated by the quantitative hybridization reaction. Urine could be stored at room temperature in Sarkosyl for at least 2 days without affecting the detectability of CMV. The clinical applicability of the test was evaluated by studying urine samples from four infants excreting CMV. Sandwich hybridization demonstrated the presence of CMV DNA in all of the specimens. These contained originally 10(5) to 10(8) CMV DNA molecules per ml. PMID:6097598

    Cytomegalovirus (CMV) remains a major cause of problems following solid organ transplantation, accounting for a significant increase in morbidity and affiliated costs. Infection with CMV following orthotopic liver transplantation (OLT) is commonly seen as a result of marked cell-mediated immunosuppression and is an independent risk factor for opportunistic and fungal infections. The role of CMV infection in acute cellular or chronic rejection remains unclear. Recent advances in diagnostic modalities, particularly the use of the antigenemia assay and the polymerase chain reaction, have provided ways to quantitate viral load during infection or disease, as well as providing a useful marker of response to therapy. Ganciclovir remains the best antiviral agent for the treatment of CMV disease, but the use of combination therapy with other antivirals or CMV immunoglobulin may improve outcome for patients with severe disease. The ideal prophylactic therapy for patients undergoing OLT remains to be identified, as tested regimens have shown variable efficacy when analyzed with regard to defined risk groups. The use of risk group-specific prophylaxis may prove to be most successful, however, in terms of efficacy and cost savings. Future advances in basic CMV virology and transplant immunology will be essential in defining rational approaches to control and prevention of CMV infection and disease following liver transplantation.

  4. Functional annotation of human cytomegalovirus gene products: an update

    2014-05-01

    Full Text Available Human Cytomegalovirus is an opportunistic double-stranded DNA virus with one of the largest viral genomes known. The 235kB genome is divided in a unique long (UL and a unique short (US region which are flanked by terminal and internal repeats. The expression of HCMV genes is highly complex and involves the production of protein coding transcripts, polyadenylated long non-coding RNAs, polyadenylated anti-sense transcripts and a variety of non-polyadenylated RNAs such as microRNAs. Although the function of many of these transcripts is unknown, they are suggested play a direct or regulatory role in the delicately orchestrated processes that ensure HCMV replication and life-long persistence. This review focuses on annotating the complete viral genome based on three sources of information. First, previous reviews were used as a template for the functional keywords to ensure continuity; second, the Uniprot database was used to further enrich the functional database; and finally, the literature was manually curated for novel functions of HCMV gene products. Novel discoveries were discussed in light of the viral life cycle. This functional annotation highlights still poorly understood regions of the genome but most importantly it can give insight in functional clusters and/or may be helpful in the analysis of transcriptomics and proteomics studies.

    Full Text Available Interferon-induced BST2/Tetherin prevents budding of vpu-deficient HIV-1 by tethering mature viral particles to the plasma membrane. BST2 also inhibits release of other enveloped viruses including Ebola virus and Kaposi's sarcoma associated herpesvirus (KSHV, indicating that BST2 is a broadly acting antiviral host protein. Unexpectedly however, recovery of human cytomegalovirus (HCMV from supernatants of BST2-expressing human fibroblasts was increased rather than decreased. Furthermore, BST2 seemed to enhance viral entry into cells since more virion proteins were released into BST2-expressing cells and subsequent viral gene expression was elevated. A significant increase in viral entry was also observed upon induction of endogenous BST2 during differentiation of the pro-monocytic cell line THP-1. Moreover, treatment of primary human monocytes with siRNA to BST2 reduced HCMV infection, suggesting that BST2 facilitates entry of HCMV into cells expressing high levels of BST2 either constitutively or in response to exogenous stimuli. Since BST2 is present in HCMV particles we propose that HCMV entry is enhanced via a reverse-tethering mechanism with BST2 in the viral envelope interacting with BST2 in the target cell membrane. Our data suggest that HCMV not only counteracts the well-established function of BST2 as inhibitor of viral egress but also employs this anti-viral protein to gain entry into BST2-expressing hematopoietic cells, a process that might play a role in hematogenous dissemination of HCMV.

    Full Text Available The third cranial nerve is called the oculomotor nerve. The pathology is revealed by limitation of eye movement inward-up-down, mydriasis, loss of light reflex and ptosis. Oculomotor nerve pathologies are frequently seen in neurology practice and are situations that may be very difficult for differential diagnosis. Differential diagnosis first involves disqualifying intracranial etiologies by imaging because these intracranial etiologies may be situations that can result in death and should be primarily evaluated. If intracranial events are ruled out, generally rarer etiologic reasons with generally difficult differentiation should be researched. Viral infections are among the rare etiological reasons causing 3rd cranial nerve involvement. Our case was a 71-year old female with etiological research due to 3rd cranial nerve palsy. The patient with diabetes-linked immune deficiency was found to have cranial nerve involvement developed secondary to cytomegalovirus (CMV infection. We report this case as 3rd cranial nerve involvement is rarely observed developing linked to CMV infection.

    Childhood adversity, defined in terms of material hardship or physical or emotional maltreatment has been associated with risk for infection with cytomegalovirus (CMV) among children and adolescents, and with CMV reactivation in children and adults. The present study examined whether different dimensions of childhood experience-those pertaining to socioeconomic status (SES), physical environment, or family relationships-relate differentially to CMV serostatus and reactivation during adulthood. Participants were 140 healthy adults, aged 18-55years (41% female; 64% white). Childhood environments were assessed retrospectively and included family SES (parental housing tenure); childhood neighborhood environment (urban residence; physical conditions; safety; and social atmosphere); residential exposures (parental smoking and physical condition of home); and family relationships (parental divorce; warmth; harmony; dysfunction; parental bonding). Approximately 39% (n=53) of participants were CMV+. In individual analyses controlling for age, sex, race, body mass, current adult SES and smoking status, fewer years of parental home ownership, having a parent who smoked, and living in a poorly maintained or unsafe neighborhood each were associated with greater odds of infection with CMV. By comparison, in individual analyses limited to CMV+ participants, less family warmth, less harmony, greater dysfunction, and suboptimal parental bonding each were related to higher antibody levels, independent of the aforementioned covariates. Findings were not attributable to current adult perceptions of psychological stress or relative levels of emotional stability. These results suggest that different types of childhood adversity may be associated with differential effects on CMV infection and latency. PMID:24675032

    Objective:To determine the prevalence of rubella and cytomegalovirus (CMV) among women in Tabriz City, Iran in 2013. Methods: This study was carried out in numerous laboratories in city of Tabriz. In 2013, 26 618 women aged 18–35 years were enrolled in this study. Serum samples were analyzed with chemiluminescence apparatus andSPSS software was used to conduct the statistical analysis. Results:A total of 26 618 individuals were examined (10 598 cases for anti-CMV and 16 020 cases for anti-rubella). About 98.9% and 1.1% samples were reported positive and negative for CMV immunoglobulin G (IgG), respectively. The positivity for anti-CMV immunoglobulin M (IgM) antibody was found in 0.75% samples, while 99.25% were negative for the anti-CMV IgM antibody. Anti-IgG against rubella seropositivity was found in 95.8% and rubella IgM seropositivity in 0.93%. Anti-IgG against rubella seronegativity was found in 4.2% and rubella IgM seronegativity in 99.07%. Conclusions: According to the results, primary and secondary infections are usually symptomless or inconspicuous, but they can cause serious fetal damage. Routine antenatal care should therefore include serological testing to check the immune status of the woman and to diagnose any fresh virus infections that may arise.

    Human cytomegalovirus (HCMV) infects 50% of adults in the United States. HCMV can become a cause for concern in individuals who have a compromised immune system, which may occur after high-intensity exercise. The purpose of this preliminary study was to characterize the lymphocyte, monocyte, and neutrophil responses to exercise in HCMV+individuals. Participants were either positive (HCMV +) or negative (HCMV-) for HCMV. Participants visited the laboratory on 3 separate occasions: HCMV screening, 100% VO2max test, and 80% VO2max run. Mixed-model factorial ANOVA procedures with repeated measures on sampling condition were performed on absolute and relative circulating lymphocytes, monocytes, and neutrophils. Significant main effects for time for both absolute and relative values were seen for all leukocyte subsets regardless of virus status. Significant differences for absolute and relative values were seen between sampling conditions for all leukocyte subsets. We report for the first time that HCMV status does not affect circulating neutrophil responses to high-intensity exercise, though exercise-induced neutrocytosis is seen during the post-exercise and 60 min post-exercise sampling conditions, regardless of HCMV status. There is no HCMV effect on circulating monocyte responses to exercise, though exercise-induced monocytosis was seen during the post-exercise sampling condition regardless of HCMV status.

    A role for human cytomegalovirus (HCMV) in the pathogenesis of glioblastoma multiforme (GBM) was proposed more than a decade ago and has since generated a considerable debate as a possible therapeutic target. We investigate the presence of HCMV in the specimens of patients with GBM treated in our centre. This is a retrospective cohort study to investigate the presence of HCMV by routine immunohistochemical stains and polymerase chain reaction (PCR)-based molecular analysis on formalin-fixed-paraffin-embedded tissue of all patients with GBM treated in our hospital in 2009-2013 (5 years). The evaluation of positivity by immunohistochemistry (IHC) was semi-quantitative. The molecular analysis was performed by extracting the tumour DNA from representative paraffin-embedded tissue blocks and amplified for detection by a sensitive real time PCR (RT-PCR) CMV assay. During the study period, we treated 45 patients with GBM; however, adequate pathology tissue materials were available only for 32 patients. All the pathology material was reviewed and the diagnosis was confirmed. All the cases were found to be negative for CMV expression by our IHC and RT-PCR CMV assay. Our study has shown no expression of CMV in GBM. Our results were similar to other recent reports that concluded insufficient evidence to recommend routine testing for CMV in GBM or treatment as an add-on therapy. PMID:26742571

    Full Text Available Abstract Background A possible association between human cytomegalovirus (HCMV infection and colorectal cancer progression has been inferred by the identification in tumour tissues of HCMV antigens and specific viral DNA or RNA sequences. To further investigate the relationship between HCMV and colorectal cancers we developed qualitative and quantitative PCR assay to detect HCMV DNA in 56 formalin-fixed paraffin-embedded (FFPE tissue samples from patients belonging to 4 different histological phenotypes: adenoma; poorly, moderately and well differentiated adenocarcinomas. Results Of the 56 FFPE tested tissue samples, 6 (11% were positive for HCMV nested PCR amplification, and more precisely 1 (5% of 20 cases of adenoma and 5 (21% of 24 cases of moderately differentiated adenocarcinoma. No PCR positivity was obtained in samples from well and poorly differentiated adenocarcinomas. Conclusion Our observations suggest that there is no evidence of a direct association between HCMV and colorectal cancer. Moreover, the results obtained are not supportive of a causal role of HCMV in the processes of carcinogenesis and/or progression of colorectal cancer. However, the fact that the virus may present a "hit and run" like-mechanism and HCMV can thus only be detectable at a particular stage of a processing adenocarcinoma, suggests that a significant number of colorectal cancers might have been the subject of HCMV infection that could contribute to trigger the oncogenic differentiation. Our analysis does not exclude the possibility of HCMV infection subsequent viral clearance.

    Background There has been increasing interest in the research into cytomegalovirus (CMV) pneumonia after liver transplantation (LT). This study was undertaken to investigate the immunomodulatory therapy of CMV pneumonia after LT.Methods Six patients with CMV pneumonia after LT from October 2003 to November 2005 were analyzed retrospectively. They were diagnosed according to clinical manifestations, chest X-ray findings and pathogenic changes and given comprehensive therapy including mainly immunomodulation therapy and anti-viral medication. At the early stage of CMV pneumonia, the dose of immunosuppressive agents was decreased or ceased, instead replaced by immunoenhancement therapy. During recovery period from CMV pneumonia, the dose of immunosuppressive agents was given again or enhanced, and immunoenhancement therapy was ceased.The liver function of the patients was monitored closely during the treatment.Results In this series, five patients were survived and one died. The liver function of the six patients remained normal during the treatment, and no episode of acute rejection took place.Conclusions Poor immunity is the pathogenic basis of CMV pneumonia after LT. At early stage of CMV pneumonia, the immunity of the patients should be enhanced, and during the recovery period from CMV pneumonia, immunosuppresants shoud be given again but immunoenhancement therapy ceased. Individualized immunomodulatory therapy is essential to the treatment of CMV pneumonia after LT.

    The human cytomegalovirus (HCMV) IE86 Cdna was cloned into Pgex-2T and fusion protein GST-IE86 was expressed in E. Coli. SDS-PAGE and Western blot assay indicated that fusion protein GST-IE86 with molecular weight of 92 ku is soluble in the supernatant of cell lysate. Protein GST and fusion protein GST-IE86 were purified by affinity chromatography. The technology of co-separation and specific affinity chromatography was used to study the interactions of HCMV IE86 protein with some transcriptional regulatory proteins and transcriptional factors. The results indicated that IE86 interacts separately with transcriptional factor TFIIB and promoter DNA binding transcription trans-activating factors SP1, AP1 and AP2 to form a heterogenous protein complex. These transcriptional trans-activating factors, transcriptional factor and IE86 protein were adsorbed and retained in the affinity chromatography simultaneously. But IE86 protein could not interact with NF-Кb, suggesting that the function of IE86 protein that can interact with transcriptional factor and transcriptional trans-activating factors has no relevance to protein glycosylation. IE86 protein probably has two domains responsible for binding transcriptional trans-activating regulatory proteins and transcriptional factors respectively, thus activating the transcription of many genes. The interactions accelerated the assembly of the transcriptional initiation complexes.

    Objective: To explore the risk factors and prophylaxis and treatment of cytomegalovirus interstitial pneumonitis(CMV-IP) after allogeneic peripheral blood stem cell transplantation (allo-PBSCT). Methods: 43 patients who received allo-PBSCT were allocated to either a Gancyclovir(GCV)-prophylaxis group (n=19) or a non-GCV prophylaxis group (n=24).A comparison was made of the incidence of CMV-IP in patients given or not given prophylactic gancyclovir. Results: 9patients in non-GCV prophylaxis group developed late CMV-IP (P<0.05). Graft-versus-host-disease (GVHD) may be associated with a high risk of CMV-IP. 5 cases of CMV-IP were successfully treated with GCV, but 3 cases died of CMV-IP.The most common adverse event of GCV was neutropenia, but was reversible. Conclusion: CMV infection was a major cause of interstitial pneumonitis after allo-PBSCT, which correlated strongly with the severity of GVHD. Gancyclovir was shown to be effective in both prophylaxis and treatment of CMV-IP.

  15. Prophylaxis of cytomegalovirus infection with ganciclovir in allogeneic marrow transplantation

    International Nuclear Information System (INIS)

    Cytomegalovirus (CMV) infection is one of the most common causes of morbidity and mortality after allogeneic marrow transplantation. We studied 14 consecutive CMV-seropositive patients adding ganciclovir (2.5 mg/kg i.v. every 8 hours for 7 days prior to transplant and 6 mg/kg three times a week after neutrophils became >0.5x109/l and the patients were platelet transfusion-independent until d 70) to our previous prophylaxis regimen which consisted of intravenous immunoglobulin and acyclovir. The result was compared with 30 consecutive patients whom we studied with our previous regimen. The addition of ganciclovir did not cause any extra toxicities. The incidence of interstitial pneumonitis and cumulative probability of CMV excretion in the first 100 d post-transplantation was significantly reduced (p = 0.038 and p = 0.035 respectively). The result shows that addition of ganciclovir significantly decreased the incidence of CMV infection in the early post-transplantation period. (au)

    The link between cytomegalovirus (CMV) infection and inflammatory bowel diseases remains an important subject of debate. CMV infection is frequent in ulcerative colitis (UC) and has been shown to be potentially harmful. CMV reactivation needs to be diagnosed using methods that include in situ detection of viral markers by immunohistochemistry or by nucleic acid amplification techniques. Determination of the density of infection using quantitative tools (numbers of infected cells or copies of the genome) is particularly important. Although CMV reactivation can be considered as an innocent bystander in active flare-ups of refractory UC, an increasing number of studies suggest a deleterious role of CMV in this situation. The presence of colonic CMV infection is possibly linked to a decreased response to steroids and other immunosuppressive agents. Some treatments, notably steroids and cyclosporine A, have been shown to favor CMV reactivation, which seems not to be the case for therapies using anti-tumor necrosis factor drugs. According to these findings, in flare-ups of refractory UC, it is now recommended to look for the presence of CMV reactivation by using quantitative tools in colonic biopsies and to treat them with ganciclovir in cases of high viral load or severe disease.

    Full Text Available Cytomegalovirus causes significant morbidity and mortality in AIDS patients and those having undergone bone marrow or another transplant. PP65 antigenemia is based on detecting viral antigen in peripheral blood leukocytes through immunochemistry and by monitoring the infection in immunocompromised individuals. The present study aimed to set up this diagnostic technique in AIDS patients with active cytomegalovirus infection and verify its occurrence in the Botucatu region of São Paulo state, Brazil. Fifty patients, 35 men and 15 women aged from 24 to 69 years, were recruited from those attended at the Department of Tropical Diseases of Botucatu Medical School, UNESP, and divided into three groups according to CD4+ T lymphocyte counts and antiretroviral treatment. The control group comprised bone marrow transplant patients. Fourteen AIDS patients with low CD4+ cell counts tested positive for PP65 antigenemia, which could predict cytomegalovirus infection and indicate prophylactic treatment.

    Hemophagocytic lymphohistiocytosis (HLH) is a rare, frequently under-recognized condition associated with multi-organ failure and very high mortality. A 44-year-old woman was admitted with a 4-day history of fever, headache, delirium, and dyspnea. She progressed rapidly to type 1 respiratory failure and required intubation and mechanical ventilation. Laboratory tests showed pancytopenia, abnormal liver enzyme levels, elevated triglyceride level, and elevated ferritin level. Bone marrow biopsy showed features of HLH. Computed tomography scan showed bilateral consolidation. Bronchoalveolar lavage was positive for cytomegalovirus. She was treated with ganciclovir, methylprednisolone, broad spectrum antibiotics, and cytomegalovirus hyperimmunoglobulin without clinical response. Given the poor prognosis and reports of success in pediatric HLH, anakinra 100 µg subcutaneously daily was commenced. There was rapid defervescence, resolution of delirium, and improvement in gas exchange, leading to complete recovery. This case illustrates successful treatment of HLH associated with cytomegalovirus pneumonitis with the interleukin 1 inhibitor anakinra. PMID:26839691

    Influenza infection manifests in a wide spectrum of severity, including symptomless pathogen carriers. We conducted a systematic review and meta-analysis of 55 studies to elucidate the proportional representation of these asymptomatic infected persons. We observed extensive heterogeneity among these studies. The prevalence of asymptomatic carriage (total absence of symptoms) ranged from 5.2% to 35.5% and subclinical cases (illness that did not meet the criteria for acute respiratory or influenza-like illness) from 25.4% to 61.8%. Statistical analysis showed that the heterogeneity could not be explained by the type of influenza, the laboratory tests used to detect the virus, the year of the study, or the location of the study. Projections of infection spread and strategies for disease control require that we identify the proportional representation of these insidious spreaders early on in the emergence of new influenza subtypes or strains and track how this rate evolves over time and space.
