Aetiology, clinical course and outcome of sporadic acute viral hepatitis in pregnancy,

JOURNAL OF VIRAL HEPATITIS, Issue 1 2003
M. S. Khuroo
summary. Hepatitis E causes large-scale epidemics in endemic areas. The disease, during epidemics, has increased incidence and severity in pregnant women. Sporadic acute viral hepatitis (AVH) is common in endemic areas. The relationship of sporadic AVH and pregnancy has not been well studied. Over a 3-year period we prospectively studied 76 pregnant women and 337 non-pregnant women of childbearing age with sporadic acute viral hepatitis for aetiology, clinical course and outcome of disease. The aetiology in sporadic AVH was hepatitis A virus (HAV) in six (1.5%), hepatitis B virus (HBV) in 62 (15%), hepatitis C virus (HCV) in seven (1.7%), hepatitis D virus (HDV) co-infection in six (1.5%), hepatitis E virus (HEV) in 205 (49.6%), and hepatitis non-A-to-E (HNAE) in 127 (30.7%). Sixty-five (85.5%) pregnant women and 140 (41.5%) nonpregnant women had hepatitis E. The proportion of pregnant women was 31.7% in HEV group and 5.3% in non-HEV group [P < 0.001; OR=8.3 (95%C1 4.2,16.3)]. The prevalence of HEV in pregnant women in first trimester (76.9%), second trimester (88.9%), third trimester (83.8%) and puerperium (100%) did not differ significantly (P=0.09). Forty-seven (61.8%) of the 76 pregnant women developed fulminant hepatic failure (FHF), 69.2% in HEV group and 10% in non-HEV group (P < 0.001). Thirty-four (10.1%) nonpregnant women developed fulminant hepatic failure, 10% in HEV group and 9.7% in non-HEV group (P=0.86). FHF had occurred in four (40%) of 10 patients with HE in first trimester as against 41 (74.5%) of 55 patients in second trimester and beyond (P=0.015). Amongst the major complications of fulminant hepatic failure, cerebral oedema (53.2%) and disseminated intravascular coagulation (21.3%) occurred more often in pregnant women than in nonpregnant women (29.4% and 2.8%; P=0.03 and 0.016, respectively) while infections occurred more often in nonpregnant women (36.1%) than in pregnant women (10.6%; P=0.003). Fifty (61.7%) patients with FHF died [25 (53.2%) pregnant women and 25 (69.5%) nonpregnant women (P=0.06)]. Cerebral oedema and HEV aetiology were independent variables of survival in patients with FHF. Patients with cerebral oedema had worse prognosis and patients with HEV aetiology had best chances of survival. Hence HEV was the most common cause of sporadic AVH in this endemic area. High proportion of pregnant women and increased severity of disease in pregnancy were limited to patients with hepatitis E. Sporadic AVH caused by agents other than HEV did not show any special predilection to or increased severity in pregnancy. FHF in pregnant women caused by HEV was an explosive disease with short pre- encephalopathy period, rapid development of cerebral oedema and high occurrence of disseminated intravascular coagulation and may represent a severe manifestation of a Schwartzmann-like phenomenon.

Number IV Erythema multiforme

ORAL DISEASES, Issue 5 2005
P Farthing
Erythema multiforme (EM) is an acute mucocutaneous hypersensitivity reaction characterised by a skin eruption, with or without oral or other mucous membrane lesions. Occasionally EM may involve the mouth alone. EM has been classified into a number of different variants based on the degree of mucosal involvement and the nature and distribution of the skin lesions. EM minor typically affects no more than one mucosa, is the most common form and may be associated with symmetrical target lesions on the extremities. EM major is more severe, typically involving two or more mucous membranes with more variable skin involvement , which is used to distinguish it from Stevens-Johnson syndrome (SJS), where there is extensive skin involvement and significant morbidity and a mortality rate of 5-15%. Both EM major and SJS can involve internal organs and typically are associated with systemic symptoms. Toxic epidermal necrolysis (TEN) may be a severe manifestation of EM, but some experts regard it as a discrete disease. EM can be triggered by a number of factors, but the best documented is preceding infection with herpes simplex virus (HSV), the lesions resulting from a cell mediated immune reaction triggered by HSV,DNA. SJS and TEN are usually initiated by drugs, and the tissue damage is mediated by soluble factors including Fas and FasL. [source]


Review of the etiologic heterogeneity of the oculo-auriculo-vertebral spectrum (Hemifacial Microsomia)*

ORTHODONTICS & CRANIOFACIAL RESEARCH, Issue 3 2007
JK Hartsfield
Structured Abstract Author,,, James K. Hartsfield Hemifacial microsomia is a congenital asymmetry of the lower face that may be associated with other cranial and extracranial anomalies. The variability of its severity, and wide range of anomalies that have been reported with it in some cases has resulted in these composite manifestations being given a number of names, including oculo-auriculo-vertebral spectrum (OAVS). Etiology is often stated to be a perturbation of embryonic blood flow in the developing region, although other factors may also play a role in some cases. Depending on what is considered to be minimum criteria for affected classification, what is often to be presumed to be a sporadic event in a family may be the more severe manifestation of a familial condition. Etiological factors are clearly heterogeneous, the investigation of which is confounded by not only the lack of a refined affected phenotype, but also the apparent influence of genetic factors in some instances that directly influence phenotype perhaps through alteration of mesodermal development, or indirectly through increased susceptibility to vascular disruption. Future studies likely to advance knowledge in this area will need to incorporate an analysis of who may be minimally affected in families, so that advances in genotyping will have greater power to distinguish genetic factors that may influence OVAS through interaction with environmental factors in particular families. The same genetic-environmental factors and or etiological mechanisms may then be investigated in apparently sporadic cases. [source]


Chronic antigen ingestion protects ovalbumin sensitized mice from severe manifestation of Leishmania major infection

PARASITE IMMUNOLOGY, Issue 11-12 2008
J. C. S. SALDANHA
SUMMARY In the present work, the development of experimental leishmaniasis was examined in sensitized BALB/c mice that were chronically fed with antigen. After an oral challenge with egg white solution, the ovalbumin (Ova)-sensitized mice showed an increase in serum anti-Ova IgE and IgG1 antibodies. Lesions induced by Leishmania major infection were reduced by the ingestion of Ova in sensitized mice, as assessed by reduced footpad growth, lower parasite loads and improved pathological outcome compared to sham sensitized mice. Moreover, such findings were connected to a shift to a Th1 response involving higher IFN-, production and serum levels of IgG2a anti- Leishmania antigens. The data appear to corroborate the suggestion that chronic ingestion of an antigen by sensitized mice modulates the immunological system through a shift in cytokine release, exhibiting a healing response and resistance to L. major infection.

Concurrent and Discriminant Validity of DSM-IV Symptoms of Impaired Control Over Alcohol Consumption in Adolescents

ALCOHOLISM, Issue 4 2002
Tammy Chung
Background: Little research has examined impaired control over alcohol consumption in adolescents. This study examined the concurrent and discriminant validity of two DSM-IV dependence criteria that reflect impaired control over drinking: "using more or longer than intended" (Larger/Longer) and "persistent desire or unsuccessful efforts to quit or cut down" (Quit/Cut Down). Methods: Adolescent drinkers, ages 13,19 (N= 173), were recruited from addictions treatment (76%) and community sources (24%). A modified SCID that included assessment of alcohol craving and questionnaires measuring dependence severity, attempts to limit drinking, and impulsivity were administered. Results: Larger/Longer had higher prevalence and an earlier onset than Quit/Cut Down, suggesting that the symptoms respectively represent milder and more severe manifestations of impaired control over drinking. Both symptoms were associated with drinking frequency, dependence severity, episodes of passing out, and an independent measure of unsuccessful attempts to limit drinking. Alcohol craving was associated with both Larger/Longer and Quit/Cut Down. Impulsivity was correlated with Larger/Longer but not Quit/Cut Down. Conclusions: Larger/Longer and Quit/Cut Down demonstrated adequate concurrent validity. The two symptoms were distinguished by severity and differential relations with impulsivity, suggesting that Larger/Longer and Quit/Cut Down reflect different types of impaired control over alcohol consumption. Results suggest the need for improved description and scaling of the impaired control construct in adolescents. [source]


Clinical outcomes of diabetic foot management with Circulat

PHYTOTHERAPY RESEARCH, Issue 10 2008
J. A. Olalde
Abstract Major and minor lower-extremity amputation is a common complication among diabetics. Various sources indicate diabetic foot ulcer prevalence at between 2.2% and 15% in diabetics. This study evaluates the efficacy and tolerance of a standardized plant extract combination, Circulat, developed for the prevention and treatment of severe manifestations of type 2 diabetes, such as necrotic damage of the foot. Thus, a retrospective cohort study was carried out in 174 patients treated with Circulat with diabetic foot grades D1,D3, according to The University of Texas Wound Classification System, in 50 medical centers, from 2004 to 2007. Circulat obtained 50.57% complete cure of diabetic foot, significant improvement in 37.9% and prevented amputation in 88.5% of the study's total population. The treatment was well tolerated. Four patients (2.3%) had slight gastrointestinal unrest which did not warrant suspension of treatment. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Financial Issues Constraining the Use of Pancreata Recovered for Islet Transplantation: A White Paper

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 8 2008
J. F. Markmann
Islet transplantation is a very promising therapy for select patients with type 1 diabetes. Continued clinical investigation is required to define the long-term safety and efficacy outcomes before the procedure will be accepted as a standard of care even for those with the most severe manifestations of diabetes. Threatening successful accomplishment of these and other innovative studies designed to advance the field are the complex financial cost accounting issues that pose undue burden on organ procurement organizations and transplant centers trying to manage the costs of the pancreata from deceased donors needed to isolate islets. Compounding the problem is the recent ruling by CMS regarding ,intent to transplant' (CMS-1543-R Dec. 21, 2006: Allocation of Donor Acquisition Costs Incurred by Organ Procurement Organizations) that does not account for the clinical need to complete the manufacturing process for islets before suitability and transplant intent of the pancreata involved can be determined. We provide a consensus document supported by a diverse group of stakeholders in islet transplantation to suggest actions to address this problem. [source]
