To investigate total bile acid (TBA) levels in maternal (MB) and umbilical cord blood (UCB) in normotensive, preeclamptic (PE), and PE pregnancies complicated by hemolysis elevated liver enzymes and low platelets (HELLP) syndrome in the context of ABCG2 placental gene expression levels, a recently reported placental bile acid transporter. TBA levels were determined in 83 paired MB and UCB samples of normotensive, PE and PE/HELLP pregnancies and in 22 paired arterial and venous UCB samples from uncomplicated term pregnancies. ABCG2 gene expression was measured in 104 human placentas by reverse transcriptase quantitative polymerase chain reaction. Overall, TBA levels in MB are higher compared to levels in UCB (p<0.0001), but this comparison looses statistical significance for the 11 PE/HELLP cases. TBA levels in maternal blood are increased in PE/HELLP compared to PE pregnancies (p=0.016). TBA levels in arterial and venous UCB from 22 normotensive pregnancies are not statistically different. ABCG2 expression is reduced in pregnancies where preeclampsia is further complicated by HELLP syndrome. ABCG2 expression in human placenta is not correlated with TBA levels in either the maternal or fetal compartment. Increased maternal TBA levels in PE/HELLP pregnancies indicate a relation between bile acids in the maternal circulation and HELLP syndrome. As overall TBA levels in maternal blood are increased compared to UCB, we conclude that the placenta partly protects the fetus from increased maternal TBA levels. This consistent difference in TBA levels between the maternal and fetal compartment is unrelated to the placental expression of ABCG2. Copyright © 2014 Elsevier B.V. All rights reserved.

[Case Report of Liver Rupture with Fulminant HELLP Syndrome in the 37th Gestational Week].

HELLP syndrome, characterized by the triad of hemolysis, elevated liver enzymes due to liver impairment, and low platelet count, is a hypertensive disorder in pregnancy. Although it is said to be caused by disturbed placentation in the first trimester, its clinical presentation can be seen mostly in the third trimester, but never before the completed 20 th gestational week. Predictive for its diagnosis is the reported upper abdominal pain that normally is localized under the right arc of ribs. With the aid of laboratory examination, the suspected diagnosis can be confirmed or excluded. Therapeutic options are observational treatment with the prophylaxis of respiratory distress syndrome and attempting to prolong pregnancy with the help of steroids like dexamethasone, or delivering the infant by inducing labor or performing a primary caesarian section, depending on the gestational week. Delivery is the unique causal therapy of HELLP syndrome. Clinical management is mainly influenced by the course of HELLP syndrome. There are mild forms that allow prolonging the pregnancy for several days or sometimes weeks, but also foudroyant courses with acute liver damage. We report the case of a 40-year-old, gravida 1 woman in gestational week 36+1 who was brought to our hospital in hemorrhagic shock caused by a rupture of the liver due to acute HELLP-syndrome. © Georg Thieme Verlag KG Stuttgart · New York.

To evaluate the performance of a combination of angiogenic and vasoactive biomarkers to predict the development of severe pre-eclampsia (PE)/HELLP syndrome in the third trimester. Included were 215 women referred in the third trimester to an obstetric outpatient clinic with suspected PE (mean gestational age, 35 + 4 weeks), and 94 with normal pregnancy attending a midwife clinic. Cases were categorized as having subclinical PE, essential hypertension, gestational hypertension, moderate PE, and severe PE/HELLP syndrome. Blood samples were analyzed by immunoassay and groups were compared with respect to potential clinical and biochemical biomarkers, with the primary outcome being development of severe PE/HELLP syndrome within 1 week and within 2 weeks of analysis. The most promising markers were also assessed in combination. In the patients presenting with mild to moderate symptoms of PE, the individual markers which performed best for the prediction of progression to severe PE/HELLP syndrome within 1 week and within 2 weeks of biomarker evaluation were C-terminal pro-endothelin-1 (CT-pro-ET-1) (area under the receiver-operating characteristics curve (AUC), 0.82 and 0.78, respectively), soluble fms-like tyrosine kinase-1 (sFlt-1) (AUC, 0.81 and 0.76), systolic blood pressure (AUC, 0.80 and 0.68) and midregional pro-atrial natriuretic peptide (AUC, 0.79 and 0.77). The combination of biomarkers with the best performance was CT-pro-ET-1, sFlt-1 and systolic blood pressure, achieving an AUC of 0.94 for prediction of development of severe PE/HELLP syndrome within 1 week and an AUC of 0.83 for prediction of their development within 2 weeks of biomarker evaluation. The performance of CT-pro-ET-1 for prediction of the development of PE/HELLP syndrome in the third trimester was promising, especially in combination with sFlt-1 and systolic blood pressure. This was an exploratory study and our findings should be confirmed in further studies. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd. Copyright © 2017 ISUOG.

Posterior reversible encephalopathy syndrome (PRES) is associated with several symptoms; of those, visual acuity loss, light oversensitivity (photophobia), and light flashes (photopsia) are known as PRES-related eye symptoms. We report a post-partum woman with PRES associated with hemolysis, elevated liver enzymes, and low platelets syndrome (HELLP), in whom color vision abnormality (achromatopsia) was the sole manifestation. Cesarean section was performed at 28 weeks due to headache, epigastralgia, and severe hypertension. HELLP became evident after delivery. On post-partum day 1, she complained of achromatopsia, stating: "all things look brownish-gray". Ophthalmologic examination was normal, but brain magnetic resonance imaging showed occipital lobe lesions, indicative of PRES, and, interestingly, also color vision center (area V4) lesions, suggesting that the achromatopsia had been caused by brain damage. It may be prudent to question HELLP patients concerning achromatopsia. © 2017 Japan Society of Obstetrics and Gynecology.

Background The occurrence of hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome before 20 weeks of gestation is rare. HELLP is a possible but rare syndrome in gestational surrogate pregnancies for surrogates with risk factors for development of preeclampsia. Case A 32-year-old patient with chronic hypertension and positive antinuclear antibody presented for prenatal care at 13 weeks and 1 day. She was a surrogate for the embryo of a 43-year-old couple. By 15 weeks she developed uncontrolled hypertension requiring hospitalization. She was expectantly managed until her condition deteriorated. At 16 weeks and 1 day she developed hemolysis, elevated liver enzymes, thrombocytopenia, and fetal demise. Conclusions HELLP syndrome is rare and carries a significant morbidity and mortality for the mother and fetus. Clinicians should encourage the surrogate to share her medical history with the embryo donor for appropriate counseling on pregnancy risks.

Serous retinal detachment is sometimes caused by hypertensive disorders in pregnancy and its associated conditions, in which the predominant eye symptoms are blurred vision, distorted vision, and reduced visual acuity. To our best knowledge, this is the first report of a puerperal woman with hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome in whom color vision abnormality was the first and predominant manifestation of serous retinal detachment. At 32 weeks of gestation, the 34-year-old Japanese woman underwent cesarean section due to HELLP syndrome. She complained of color vision abnormality on day 1 post-partum and ophthalmological examination revealed serous retinal detachment of both eyes. The visual acuity was preserved. With supportive therapy, her color vision abnormality gradually ameliorated and retinal detachment completely resolved on day 34 post-partum without any sequelae. Obstetricians should be aware that color vision abnormality can be the first and predominant symptom of HELLP-related serous retinal detachment. © 2015 Japan Society of Obstetrics and Gynecology.

Recently, acquired as well as genetic prothrombotic factors are associated with thrombotic events. These factors have also been related to conditions of uteroplacental insufficiency such as pre-eclampsia, HELLP syndrome and severe intrauterine growth restriction (IUGR). The aim of this study was to determine whether elevated factor VIII levels are associated with uteroplacental insufficiency, in particular pre-eclampsia, HELLP syndrome or pregnancy-induced hypertension and intrauterine growth retardation. Plasma samples of 75 women with a history of pregnancy complicated by pre-eclampsia, HELLP syndrome, pregnancy induced hypertension or intrauterine growth restriction were tested for factor VIII:C (FVIII:C) levels at a minimum of 10 weeks post-partum. Laboratory results were compared to factor VIII:C levels found in a healthy control group of 272 women. Mean factor VIII:C levels were similar at 123 IU/dl in both the patient group and the controls. In a logistic regression model, after adjusting for age and blood group, no effect of factor VIII:C levels on the risk of pregnancy complications was observed, with the exception of IUGR with (OR 2.9, CI 1.0-8.7) or without hypertension (OR 2.0, CI 0.7-6.4). If the elevated level of factor VIII would be the sole factor responsible for the increased risk observed, one would expect to find an effect of blood group on risk as well (blood group being an important determinant of FVIII:C). While no such effect could be shown a causal relationship between elevated levels of factor VIII and conditions of uteroplacental insufficiency such as pre-eclampsia, HELLP syndrome, pregnancy-induced hypertension and IUGR is not very likely.

Introduction Preeclampsia is characterized by maternal systemic anti-angiogenic and pro-inflammatory states. Syndecan-1 is a cell surface proteoglycan expressed by the syncytiotrophoblast, which plays an important role in angiogenesis and resolution of inflammation. Our aim was to examine placental syndecan-1 expression in preeclampsia with or without HELLP syndrome. Methods Placentas were obtained from women in the following groups: (1) late-onset preeclampsia (n=8); (2) early-onset preeclampsia without (n=7) and (3) with HELLP syndrome (n=8); (4) preterm controls (n=5); and (5) term controls (n=9). Tissue microarrays (TMAs) were constructed from paraffin-embedded placentas. TMA slides were immunostained for syndecan-1 and evaluated using microscopy, virtual microscopy, and semi-automated image analysis. Maternal sera from patients with preeclampsia (n=49) and controls (n=32) were immunoassayed for syndecan-1. BeWo cells were treated with Forskolin or Latrunculin-B, or kept in ischemic conditions. SDC1 expression and syndecan-1 production were investigated with qRT-PCR, confocal microscopy, and immunoassays. Results Syndecan-1 was localized to the syncytiotrophoblast apical membrane in normal placentas. Syndecan-1 immunoscores were higher in late-onset preeclampsia (p=0.0001) and early-onset preeclampsia with or without HELLP syndrome (p=0.02 for both) than in controls. Maternal serum syndecan-1 concentration was lower in preeclampsia (median: 673ng/ml, interquartile range: 459-1161ng/ml) than in controls (1158ng/ml, 622-1480ng/ml). SDC1 expression and syndecan-1 immunostainings in BeWo cells and syndecan-1 concentrations in supernatants increased during cell differentiation. Disruption of the actin cytoskeleton with Latrunculin-B decreased syndecan-1 release, while ischemic conditions increased it. Conclusions Syncytiotrophoblastic syndecan-1 expression depends on the differentiation of villous trophoblasts, and trophoblastic syndecan-1 release is decreased in preeclampsia and HELLP syndrome. This phenomenon may be related to the disturbed syncytiotrophoblastic cortical actin cytoskeleton, and associated with maternal anti-angiogenic and pro-inflammatory states in these syndromes.

Scrub typhus masquerading as HELLP syndrome and puerperal sepsis in an asymptomatic malaria patient.

Scrub typhus and malaria can involve multiple organ systems and are notoriously known for varied presentations. However, clinical malaria or scrub typhus is unusual without fever. On the other hand, altered sensorium with or without fever, dehydration, hemorrhage and hemolysis may lead to low blood pressure. Presence of toxic granules and elevated band forms in such patients can even mimic sepsis. When such a patient is in the peripartum period, it creates a strong clinical dilemma for the physician especially in unbooked obstetric cases. We present such a case where a 26-year-old unbooked female presented on second postpartum day with severe anemia, altered sensorium, difficulty in breathing along with jaundice and gum bleeding without history of fever. Rapid diagnostic test for malaria was negative and no eschar was seen. These parameters suggested a diagnosis of HELLP (Hemolysis, Elevated Liver enzymes, Low Platelet) syndrome with or without puerperal sepsis. Subsequently she was diagnosed as having asymptomatic malaria and scrub typhus and responded to the treatment of it. The biochemical changes suggestive of HELLP syndrome also subsided. We present this case to emphasize the fact that mere absence of fever and eschar does not rule out scrub typhus. It should also be considered as a differential diagnosis in patients with symptoms and signs suggesting HELLP syndrome. Asymptomatic malaria can complicate case scenario towards puerperal sepsis by giving false toxic granules and band form in such situations.

HELLP syndrome is a serious hypertensive disorder of pregnancy with important neonatal problems in the newborn. The objective of this work was to determine the characteristics of these infants and its neonatal evolution. A retrospective observational study of all newborns of mothers with HELLP syndrome born in a university hospital between January 1, 2008 and December 31, 2013 was carried out. Thirty-three infants from 28 pregnancies (five twin gestations) were studied. A descriptive and comparative analysis between groups and a multivariate analysis of factors associated with mortality in the series took place. Of 33 newborns studied (2.2 newborns/1,000 infants total), two were stillbirths (6.1% of the total) and four died after birth (12.9% of live neonates) with overall perinatal mortality of 18.2%. Pregnancies in 28 infants ended before 37 weeks (84.8%) and 11 pregnancies ended before week 32 (33.3%). Seven infants weighed<1500g (four weighed <1000g). Of the 31 live births, 13 infants were in a <10th percentile weight for gestational age (41.9%), 20 needed neonatal resuscitation (64.5%) and 14 had leukopenia at birth (45.2%). In the final logistic regression, neonatal mortality was associated with extreme prematurity regardless of underweight, leukopenia and/or need for neonatal resuscitation. Children of mothers with HELLP syndrome have a high mortality associated with extreme prematurity, independent of the presence of leukopenia, low weight for gestational age and need for neonatal resuscitation.

Heart rate of 93 beats per minute (bpm) with left atrial diameter (LAD) of 35 mm, left ventricular hypertrophy and inferior vena cava diameter (IVCD) of 8 mm at GW 32 -0/7 decreased to 48 bpm with an expanded IVCD to 25 mm, dilated left atrium (LAD to 39 mm), increased pulmonary arterial pressure, increased systemic vascular resistance (approximate 3000  dyn s/cm 5 ) and biphasic intrarenal venous flow pattern 3.5 hours prior to childbirth at GW 32 -3/7 Epigastralgia, tachycardia (160 bpm) and marked hypertension (201/111 mm Hg) occurring 2 hours after echocardiography necessitated caesarean section, with subsequent development of HELLP syndrome. Acute fluid shift from the splanchnic vasculature to central vasculature may have occurred causing HELLP syndrome as a result from vasospasm associated with sympathetic hyperactivity. The cause of bradycardia prior to tachycardia remains unclear. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

Importance of correctly interpreting magnetic resonance imaging to diagnose posterior reversible encephalopathy syndrome associated with HELLP syndrome: a case report.

PubMed

Tetsuka, Syuichi; Nonaka, Hiroaki

2017-05-25

Severe haemolysis, elevated liver enzyme levels, and low platelet count (HELLP) syndrome in pregnancy are possible underlying trigger factors for posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging (MRI) shows diffuse signal abnormalities involving the subcortical white matter in the parieto-occipital lobes. Although the diagnosis of RPES was clearly established by the distinctive reversibility of clinical and radiological abnormalities, it is difficult to distinguish from differential diagnosis. Thus, it is important to correctly interpret MRI. We describe a case of HELLP syndrome with PRES. A 38-year-old pregnant woman was admitted to our hospital as an emergency case with a complaint of upper abdominal pain and headache at 29 weeks of pregnancy and the development of HELLP syndrome. An emergency caesarean section was immediately performed. After the operation, the patient received intravenous corticosteroids, and her blood pressure was controlled. Thereafter, she showed an altered mental status. MRI showed hypersignal intense lesions in the cortical and subcortical white matter in the occipital lobes, basal ganglia and callosal splenium in both the fluid-attenuated inversion recovery (FLAIR) sequence and apparent diffusion coefficient (ADC), but these lesions were not recognized in diffusion-weighted imaging (DWI). These images were suggestive of PRES. The patient was kept in the hospital and received the appropriate treatment, after which the patient's level of consciousness improved and all laboratory tests and imaging examinations returned normal. The MRI findings were useful for the prompt diagnosis of PRES, characterized by hypersignals in FLAIR and ADC, but not in DWI. Additionally, there was an "atypical" MRI appearance of basal ganglial and callosal splenial involvement in this case, which may mistakenly lead clinicians to diagnose other aetiologies than typical PRES. It is considered that vasogenic oedema is the main pathology of PRES according to the MRI image findings. MRI is the gold standard for diagnosing PRES because it can provide information about cerebral involvement earlier than CT; further, it can be a useful tool in the differential diagnosis. This technique facilitated the prompt diagnosis and treatment of the said patient, ultimately resulting in a good outcome.

Hepatic infarction is an extremely rare and fatal complication associated with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome. It can develop into fulminant liver failure, which increases both maternal and neonatal mortality rates. A 34-year-old woman with no remarkable past medical history developed eclampsia after delivery at 40 weeks of gestation. Imaging indicated massive hepatic infarction and rupture followed by cardiac arrest and fulminant liver failure. Despite liver replacement therapy with plasma exchange and continuous hemodiafiltration, the patient gradually deteriorated with persistent bacterial infection until death at 98 days after delivery. The management of fulminant liver failure complicated with HELLP syndrome should be multidisciplinary. Liver transplantation, the only radical treatment for fulminant liver failure, is worth attempting, if applicable. © 2016 Japan Society of Obstetrics and Gynecology.

2013-01-01

Preeclampsia, HELLP syndrome (hemolysis, elevated liver enzymes, and low-platelet count), and acute fatty liver of pregnancy are the main causes of thrombotic microangiopathy and evere liver dysfunction during pregnancy and represent different manifestations of the same pathological continuum. The case of a 35-week pregnant woman who was admitted to an intensive care unit immediately after a Cesarean section due to fetal death and the presence of nausea, vomiting, and jaundice is reported. Postpartum preeclampsia and acute fatty liver of pregnancy were diagnosed. The patient developed an acute subdural hematoma and an intracerebral hemorrhage, which were subjected to neurosurgical treatment. The patient died from refractory hemolytic anemia and spontaneous bleeding of multiple organs. Preeclampsia HELLP syndrome, and acute fatty liver of pregnancy might overlap and be associated with potentially fatal complications, including intracranial hemorrhage, as in the present case. Early detection and diagnosis are crucial to ensure management and treatment success.

2015-05-01

Abnormalities in liver function tests appear in 3% of pregnancies. Severe acute liver damage can be an exclusive condition of pregnancy (dependent or independent of pre-eclampsia) or a concomitant disease. HELLP syndrome and acute fatty liver of pregnancy are the most severe liver diseases associated with pregnancy. Both appear during the third trimester and have a similar clinical presentation. Acute fatty liver may be associated with hypoglycemia and HELLP syndrome is closely linked with pre-eclampsia. Among concomitant conditions, fulminant acute hepatitis caused by medications or virus is the most severe disease. Its clinical presentation may be hyper-acute with neurological involvement and severe coagulation disorders. It has a high mortality and patients should be transplanted. Fulminant hepatic failure caused by acetaminophen overdose can be managed with n-acetyl cysteine. Because of the high fetal mortality rate, the gestational age at diagnosis is crucial.

Postpartum plasma exchange in a woman with suspected thrombotic thrombocytopenic purpura (TTP) vs. hemolysis, elevated liver enzymes, and low platelet syndrome (HELLP): a case study.

PubMed

Myers, Linda

2010-01-01

The occurrence of a hypercoagulable state and decreasing concentration of ADAMTS 13 in late pregnancy and during the postpartum period increases the risk for a woman to develop life-threatening thrombotic thrombocytopenic purpura (TTP). This is also the time of great risk for the more common obstetric complications of preeclampsia; eclampsia; and hemolysis, elevated liver functions tests, low platelets (HELLP) syndrome. These conditions are associated with high maternal and perinatal mortality. Differential diagnosis may be difficult due to the overlapping of clinical and laboratory findings, including thrombocytopenia, microangiopathic hemolytic anemia, neurologic symptoms, and renal insufficiency, making it difficult or impossible to distinguish them from TTP. Management of microangiopathic disorders encountered during pregnancy differ; therefore, an accurate diagnosis is required. Outcomes of TTP without plasma exchange therapy (TPE) are almost uniformly fatal. Early recognition and management of symptoms with prompt and aggressive TPE is essential when TTP is suspected.

Background The catastrophic variant of the antiphospholipid syndrome (APS) is a life‐threatening form of presentation of this syndrome that can be triggered by several factors. Aim To describe the characteristics of patients who developed catastrophic APS triggered during pregnancy and puerperium. Methods A review of the first 255 cases collected in the website‐based “CAPS Registry” was undertaken. Three new and unpublished cases of catastrophic APS developed during pregnancy and puerperium were added. Results Fifteen cases were identified. The mean (range) age was 27 (17–38) years. Most patients had a previous unsuccessful obstetric history. In 7 of 14 (50%) cases with available medical history, the catastrophic APS appeared during pregnancy, in 6 (43%) during the puerperium and in 1 (7%) after curettage for a fetal death. The main clinical and serological characteristics were similar to those patients with catastrophic APS triggered by other factors, except for a history of a higher prevalence of previous abortions (p<0.01). Several specific features were found, including the HELLP (haemolysis, elevated liver enzymes, low platelets) syndrome in 8 (53%) patients, placental infarctions in 4 (27%) patients, and pelvic vein thrombosis and myometrium thrombotic microangiopathy in 1 (7%) patient each. Mortality rate was high for the mothers (46%), and for the babies (54%). Conclusions It is important to consider the possibility of the development of catastrophic APS in those patients with signs of HELLP syndrome and multiorgan failure during pregnancy or puerperium, especially in those patients with previous history of abortions and/or thrombosis.

García-Miguel, F J; Mirón Rodríguez, M F; Alsina Aser, M J

2009-02-01

Acute renal failure is a serious complication of pregnancy associated with a high rate of morbidity and mortality; the incidence is currently 1 per 10,000 pregnancies. The most common causes are gestational hypertension, bleeding, sepsis, and intrinsic renal disease. Other less common pregnancy-related syndromes, such as HELLP syndrome or thrombotic microangiopathy, may also lead to kidney failure. Hemolytic uremic syndrome and thrombotic thrombocytopenic purpura are forms of thrombotic microangiopathy and although neither is specific to pregnancy, the incidence of these entities rises during gestation. The classic symptoms are fever, hemolytic microangiopathic anemia, thrombopenia, neurologic dysfunction, and kidney abnormalities. When renal involvement is the predominant manifestation, the diagnosis is usually hemolytic uremic syndrome.

Imaging is, therefore, essential in the rapid diagnosis of some of these conditions so that appropriate, life-saving treatment can be administered. This pictorial essay illustrates the multimodality imaging features of pregnancy-induced hepato-biliary disorders, such as acute fatty liver of pregnancy, preeclamsia and eclampsia, and HELLP syndrome, as well as those conditions which occur in pregnancy but are not unique to it, such as viral hepatitis, Budd-Chiari syndrome, focal hepatic lesions, biliary sludge, cholecystolithiasis, and choledocholithiasis.

Coexistence of autoimmune polyglandular syndrome type 2 and diabetes insipidus in pregnancy.

Autoimmune polyglandular syndromes are rarely diagnosed conditions characterized by the association of at least 2 organ-specific autoimmune disorders. Very few cases of these syndromes have been described during pregnancy. The authors report a case of a patient diagnosed with autoimmune thyroiditis and a history of HELLP (hemolysis, elevated liver enzymes and low platelet) syndrome in a prior pregnancy. After increasing the levothyroxine dose, she developed Addisonian crisis. Normalization of adrenal cortex function resulted in the appearance of diabetes insipidus. This report shows that pregnancy may influence the course of preexisting endocrine disorders and lead to their unmasking. Although the risk of the development of autoimmune polyglandular syndromes during pregnancy is small, they may pose a serious health problem. The possible presence of these clinical entities should be considered in every woman with 1 or more endocrine disturbances.

The kidney in pregnancy: A journey of three decades.

The spectrum of kidney disease occurring during pregnancy includes preeclampsia, hypertensive disorders of pregnancy, urinary tract infection, acute kidney injury, and renal cortical necrosis (RCN). Preeclampsia affects approximately 3-5% of pregnancies. We observed preeclampsia in 5.8% of pregnancies, and 2.38% of our preeclamptic women developed eclampsia. Severe preeclampsia and the eclampsia or hemolysis, elevated liver enzymes levels, and low platelets count (HELLP) syndrome accounted for about 40% of cases of acute kidney injury (AKI) in pregnancy. Preeclampsia/eclampsia was the cause of acute renal failure (ARF) in 38.3% of the cases. Preeclampsia was the most common (91.7%) cause of hypertension during pregnancy, and chronic hypertension was present in 8.3% of patients. We observed urinary tract infection (UTI) in 9% of pregnancies. Sepsis resulting from pyelonephritis can progress to endotoxic shock, disseminated intravascular coagulation, and AKI. The incidence of premature delivery and low birth weight is higher in women with UTI. The incidence of AKI in pregnancy with respect to total ARF cases has decreased over the last 30 years from 25% in 1980s to 5% in 2000s. Septic abortion-related ARF decreased from 9% to 3%. Prevention of unwanted pregnancy and avoidance of septic abortion are key to eliminate abortion-associated ARF in early pregnancy. The two most common causes of ARF in third trimester and postpartum periods were puerperal sepsis and preeclampsia/HELLP syndrome. Pregnancy-associated thrombotic thrombocytopenic purpura/hemolytic uremic syndrome and acute fatty liver of pregnancy were rare causes of ARF. Despite decreasing incidence, AKI remains a serious complication during pregnancy.

Neurological disorders caused by pregnancy and puerperium include the posterior reversible encephalopathy syndrome, the amniotic fluid embolism syndrome (AFES), the postpartum angiopathy due to reversible vasoconstriction syndrome, and the Sheehan syndrome. Hypertension and proteinuria are the hallmarks of preeclampsia, seizures define eclampsia. Hemolysis, elevated liver enzymes and low platelets constitute the HELLP syndrome. Vision disturbances including cortical blindness occur in the posterior reversible encephalopathy syndrome (PRES). The Sheehan syndrome presents with panhypopituitarism post partum due to apoplexia of the pituitary gland in severe peripartal blood loss leading to longstanding hypotension. Some neurological disorders occur during pregnancy and puerperium with an increased frequency. These include stroke, sinus thrombosis, the restless legs syndrome and peripheral nerve syndromes, especially the carpal tunnel syndrome. Chronic neurologic diseases need an interdisciplinary approach during pregnancy. Some anticonvulsants double the risk of birth defects. The highest risk exists for valproic acid, the lowest for lamotrigine and levetiracetam. For MS interval treatment, glatiramer acetate and interferones seem to be safe during pregnancy. All other drugs should be avoided. © Georg Thieme Verlag KG Stuttgart · New York.

Placental protein-13 (PP13) is involved in placental invasion and has been suggested as a maternal serum marker of preeclampsia (PE) development. However, the discriminatory ability of PP13 in first trimester has not been completely clarified. PP13 was measured in first trimester (week 10+3-13+6) maternal serum from 120 PE pregnancies and 267 control pregnancies and was correlated with clinical parameters. The population screening performance of PP13 in combination with the PE markers pregnancy associated plasma protein A (PAPPA) and free leptin index (fLI) was assessed by Monte Carlo simulation. In severe PE (including HELLP) cases (n=26) the median PP13 concentration was 35.8 pg/mL (range: 17.8-85.5 pg/mL) and in PE pregnancies (n=10) with birth prior to week 34, the median PP13 concentration was 30.6 pg/mL (13.1-50.1 pg/mL), compared to controls with a median of 54.8 pg/mL (range: 15.4-142.6 pg/mL) (p<0.04). The population screening detection rate (DR) for a false-positive rate of 10% for severe PE and HELLP was 26% for PP13, 28% for PP13+PAPP-A, 33% for PP13+fLI, and 40% for PP13+PAPP-A+fLI. PP13 is a marker of severe PE and HELLP syndrome. The screening performance of PP13 can be markedly improved by combining it with fLI and PAPP-A.

Little is known in the United States about the epidemiology of liver diseases that develop only during (are unique to) pregnancy. We investigated the incidence of liver diseases unique to pregnancy in Olmsted County, Minnesota, and long-term maternal and fetal outcomes. We identified 247 women with liver diseases unique to pregnancy from 1996 through 2010 using the Rochester Epidemiology Project database. The crude incidence rate was calculated by the number of liver disease cases divided by 35,101 pregnancies. Of pregnant women with liver diseases, 134 had preeclampsia with liver dysfunction, 72 had hemolysis-associated increased levels of liver enzymes and low-platelet (HELLP) syndrome, 26 had intrahepatic cholestasis of pregnancy, 14 had hyperemesis gravidarum with abnormal liver enzymes, and 1 had acute fatty liver of pregnancy. The crude incidence of liver diseases unique to pregnancy was 0.77%. Outcomes were worse among women with HELLP or preeclampsia than the other disorders--of women with HELLP, 70% had a premature delivery, 4% had abruptio placentae, 3% had acute kidney injury, and 3% had infant death. Of women with preeclampsia, 56.0% had a premature delivery, 4% had abruptio placentae, 3% had acute kidney injury, and 0.7% had infant death. After 7 median years of follow-up (range, 0-18 years), 14% of the women developed recurrent liver disease unique to pregnancy; the proportions were highest in women with initial hyperemesis gravidarum (36%) or intrahepatic cholestasis of pregnancy (35%). Women with preeclampsia were more likely to develop subsequent hepatobiliary diseases. We found the incidence of liver disease unique to pregnancy in Olmsted County, Minnesota, to be lower than that reported from Europe or US tertiary referral centers. Maternal and fetal outcomes in Olmsted County were better than those reported from other studies, but fetal mortality was still high (0.7%-3.0%). Women with preeclampsia or HELLP are at higher risk for peripartum complications and subsequent development of comorbidities. Copyright © 2016 AGA Institute. Published by Elsevier Inc.

To determine the etiology and outcome of Acute Renal Failure (ARF) in pregnancy. A case series. Nephrology Department of the Jinnah Postgraduate Medical Centre, Karachi, from August 2007 to July 2008. Pregnant women who were healthy previously and had developed ARF, diagnosed on oliguria (urine output <400 ml/day) and mounting azotemia (serum creatinine > 2 mg%) were included in the study. Percutaneous renal biopsy was performed for delayed recovery, i.e. after three weeks. Patients were followed up for a period of 6 months. Percentages were calculated for qualitative variables i.e. causes of ARF, mortality, morbidity and outcome in form of complete recovery, partial recovery, demise and non-recovery. A total of 43 patients with pregnancy-related ARF were included in the study. The puerperal group comprised 36 patients (83.7%). Haemorrhage was the etiology for ARF in 25 (58.1%), antepartum haemorrhage APH in 8 (18.6%) and postpartum haemorrhage PPH in 16 (37.2%) of patients. In 12 (27.9%), puerperal sepsis was the etiological factor, while 4 (9.3%) patients had DIC on presentation. Pre-eclampsia, eclampsia and HELLP syndrome accounted for 5 (11.6%). While 1 (2.3%) was diagnosed with hemolytic uremic syndrome and another one was diagnosed as ARF secondary to hypotension produced by hyperemesis gravidarum. Renal biopsy was performed in 31 patients showing that 10 had acute cortical necrosis and 21 had acute tubular necrosis. Maternal mortality was 16.2% (n=7). Of the 36 (83.7%) surviving patients, 18 (41.4%) had complete recovery of renal function; 12 (27.9%) had partial recovery; and 6 (13.9%) required chronic dialysis. Pregnancy-related ARF was associated with poor outcome. Antepartum and postpartum haemorrhage were the most common cause of ARF in pregnancy.

Because of a switch in energy-producing substrate utilization from glucose in the fetal period to fatty acids postnatally, intrauterine morbidity of fatty acid oxidation defects has widely been denied. We report the intrauterine development of severe cardiomyopathy in a child with mitochondrial trifunctional protein deficiency after 27 weeks of gestation. The child was born at 31 weeks of gestation and died on day 3 of life. Severe cardiac mitochondrial proliferation was observed. Molecular analysis of both TFP genes was performed and confirmed a homozygous mutation in the TFP alpha-subunit introducing a stop codon at amino acid position 256 (g.871C>T, p.R256X). Despite severe intrauterine decompensation in our patient, no HELLP-syndrome or acute fatty liver of pregnancy was observed in the mother. In the pathogenesis of maternal HELLP-syndrome, toxic effects of accumulating long-chain hydroxy-acyl-CoAs or long-chain hydroxy-acylcarnitines are suspected. In our patient, acylcarnitine analysis on day 2 of life during severest metabolic decompensation did not reveal massive accumulation of long-chain hydroxy-acylcarnitines in blood, suggesting other pathogenic factors than toxic effects. The most important pathogenic mechanism for the development of intrauterine cardiomyopathy appears to be significant cardiac energy deficiency. In conclusion, our report implicates that fatty acid oxidation does play a significant role during intrauterine development with special regard to the heart. Severe cardiac mitochondrial proliferation in TFP deficiency suggests pathophysiologically relevant energy deficiency in this condition.

Neuromyelitis optica (NMO) is a demyelinating syndrome characterized by optic neuritis and acute myelitis with poor recovery and a progressive course. We report a poor outcome complicated by posterior reversible encephalopathy syndrome (PRES) and eclampsia and review available literature and current evidence for anticipation of adverse fetal and maternal effects. After a pregnancy complicated by multiple admissions for painful NMO exacerbations, a primiparous patient with seropositive NMO presented at 31 + 3/7 weeks with eclampsia, HELLP and subsequent fetal death. MRI confirmed PRES. NMO may be associated with eclampsia and leads to adverse maternal and fetal outcomes. Posited mechanisms include antibody-mediated placental damage and a heightened risk of eclampsia-associated PRES. Further characterization of the course of NMO and its relationship with pregnancy outcomes in larger series would be invaluable.

The oxysterol 27-hydroxycholesterol (27-OHC) plays an important role in the regulation of cholesterol homeostasis. Pregnancy pathologies like preeclampsia (PE), HELLP-syndrome (HELLP), intrauterine growth restriction (IUGR) and intrahepatic cholestasis in pregnancy (ICP) are linked to disturbances in lipid metabolism. In the present study, we hypothesized a specific gestational regulation of 27-OHC and compromised 27-OHC levels due to placental and hepatic diseases in pregnancy resulting in a dysregulation of lipid metabolism. The 27-OHC was measured by gas-chromatography-mass spectrometry (GC-MS) and related to cholesterol concentrations. In the longitudinal cohort, a complete set of samples of healthy patients (n = 33) obtained at three different time points throughout gestation and once post-partum was analyzed. In the cross sectional cohort, patients with pregnancy pathologies (IUGR n = 14, PE n = 14, HELLP n = 7, ICP n = 7) were matched to a control group (CTRL) of equal gestational ages. The 27-OHC levels already increased in the first trimester despite lower TC concentrations (p < 0.05). During the course of pregnancy, a subtle rise in 27-OHC concentrations results in an overall decrease of 27-OHC/TC ratio in between the first (p < 0.05) and second trimester. The ratio remains stable thereafter including the post-partum period. No significant differences have been observed in pregnancy pathologies as compared to the CTRL group. In conclusion, 27-OHC may have a compensatory role in cholesterol metabolism early in pregnancy. The conserved 27-OHC/TC ratio in pregnancy pathologies suggest that neither the placenta nor the liver is majorly involved in the regulation of 27-OHC metabolism.

Atypical haemolytic uraemic syndrome is one of the main variants of thrombotic microangiopathy, and is characterized by excessive complement activation in the microvasculature. It is also characterised by the clinical triad; non-immune haemolytic anaemia, thrombocytopenia, and acute renal failure. In addition, 60% of patients have mutations in the genes encoding complement regulators (factor H, factor I, membrane cofactor proteins, and thrombomodulin), activators (factor B and C3), as well as autoantibodies against factor H. Multiple factors are required for the disease to manifest itself, including a trigger and gene mutations with adequate penetration. Being one of the differential diagnoses of preeclampsia- eclampsia and HELLP syndrome means that the clinician must be familiar with the disease due to its high mortality, which can be modified with early diagnosis and comprehensive treatment.

Antiphospholipid Syndrome during pregnancy: the state of the art

Obstetric complications are the hallmark of antiphospholipid syndrome. Recurrent miscarriage, early delivery, oligohydramnios, prematurity, intrauterine growth restriction, fetal distress, fetal or neonatal thrombosis, pre-eclampsia/eclampsia, HELLP syndrome, arterial or venous thrombosis and placental insufficiency are the most severe APS-related complication for pregnant women. Antiphospholipid antibodies promote activation of endothelial cells, monocytes and platelets, causing an overproduction of tissue factor and thromboxane A2. Complement activation might have a central pathogenetic role. These factors, associated with the typical changes in the hemostatic system during normal pregnancy, result in a hypercoagulable state. This is responsible of thrombosis that is presumed to provoke many of the pregnancy complications associated with APS. Obstetric care is based on combined medical-obstetric high-risk management and treatment with the association between aspirin and heparin. This review aims to deter- mine the current state of the art of APS by investigating the knowledge achievements of recent years, to provide the most appropriate diagnostic and therapeutic management for pregnant women suffering from this syndrome.

There is discrepancy in the literature on the definitions of severe and early-onset pre-eclampsia. We aimed to determine those definitions for clinical purposes and to introduce them in the classification of the hypertensive disorders of pregnancy for publication purposes. We circulated a questionnaire to the International Committee of the International Society for the Study of Hypertension in Pregnancy focusing on the thresholds for defining severe preeclampsia and the gestation at which to define early-onset preeclampsia, and on the definition and inclusion of the HELLP syndrome or other clinical features in severe preeclampsia. The questions were closed, but all answers had space for more open detailed comments. There was a general agreement to define preeclampsia as severe if blood pressure was >160mmHg systolic or 110mmHg diastolic. There was scarce agreement on the amount of proteinuria to define severity. The HELLP syndrome was considered a feature to include in the severe classification. Most investigators considered early-onset preeclampsia as that occurring before 34weeks. A definition of pre-eclampsia is paramount for driving good clinical practice. Classifications on the other hand are useful to enable international comparisons of clinical data and outcomes. We used the results of this survey to update our previous classification for the purposes of providing clinical research definitions of severe and early onset pre-eclampsia that will hopefully be accepted in the international literature.

Background Preeclampsia is one of the leading causes of maternal and neonatal morbidity and mortality in the world, but its appearance is still unpredictable and its pathophysiology has not been entirely elucidated. Genetic studies have associated single nucleotide polymorphisms in genes encoding nitric oxide synthase and matrix metalloproteases with preeclampsia, but the results are largely inconclusive across different populations. Objectives To investigate the association of single nucleotide polymorphisms (SNPs) in NOS3 (G894T, T-786C, and a variable number of tandem repetitions VNTR in intron 4), MMP2 (C-1306T), and MMP9 (C-1562T) genes with preeclampsia in patients from Southeastern Brazil. Methods This prospective case-control study enrolled 77 women with preeclampsia and 266 control pregnant women. Clinical data were collected to assess risk factors and the presence of severe complications, such as eclampsia and HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome. Results We found a significant association between the single nucleotide polymorphism NOS3 T-786C and preeclampsia, independently from age, height, weight, or the other SNPs studied, and no association was found with the other polymorphisms. Age and history of preeclampsia were also identified as risk factors. The presence of at least one polymorphic allele for NOS3 T-786C was also associated with the occurrence of eclampsia or HELLP syndrome among preeclamptic women. Conclusions Our data support that the NOS3 T-786C SNP is associated with preeclampsia and the severity of its complications. PMID:26317342

The anaemia progressed to become life-threatening for both the pregnant women and the foetus, which brought the following questions into consideration: diagnosis of anaemia during pregnancy; dosing of corticosteroid therapy; possibility of giving birth to a viable foetus and prognosis for next pregnancies. Owing to the inter-disciplinary efforts, the life and health of this pregnant woman were preserved, but the foetus was lost.

Acute Kidney Injury in Pregnancy-specific Disorders.

The incidence of acute kidney injury in pregnancy (P-AKI) has declined significantly over the last three decades in developing countries. However, it is still associated with significant fetomaternal mortality and morbidity. The diagnosis of P-AKI is based on the serum creatinine increase. The usual formulas for estimating glomerular filtration rate (GFR) are not validated in this population. The incidence of P-AKI with respect to total AKI cases has decreased in the last three decades from 25% in 1980s to 9% in 2000s at our centre. During the first trimester of gestation, AKI develops most often due to septic abortion or hyperemesis gravidarum. Septic abortion related AKI with respect to total AKI decreased from 9% to 5% in our study. Prevention of unwanted pregnancy and avoidance of septic abortion are keys to eliminate abortion associated AKI in early pregnancy. However, we have not seen AKI on account of hyperemesis gravidarum over a period of 33 years at our center. In the third trimester, the differential diagnosis of AKI in association with pregnancy specific conditions namely preeclampsia/HELLP syndrome, acute fatty liver of pregnancy and thrombotic microangiopathies of pregnancy (P-TMA) is more challenging, because these 3 conditions share several clinical features of thrombotic microangiopathy which makes the diagnosis very difficult on clinical grounds. It is imperative to distinguish these conditions to make appropriate therapeutic decisions. Typically, AFLP and HELLP syndrome improve after delivery of the fetus, whereas plasma exchange is the first-line treatment for pregnancy associated thrombotic microangioathies (P-TMA). We observed that preclampsia/eclampsia is the most common cause of AKI in late third trimester and postpartum periods followed by puerperal sepsis and postpartum hemorrhage. Pregnancy-associated thrombotic microangiopathies (aHUS/TTP) and AFLP are rare causes of AKI during pregnancy in developing countries.

Can very high level of D-dimer exclusively predict the presence of thromboembolic diseases?

PubMed

Ho, Chao-Hung

2011-04-01

D-dimer quantitative test is mainly used to rule out the presence of thromboembolic diseases (TEDs). Whether very high D-dimer (100 times above the cutoff point) can exclusively indicate the presence of TED should be known. D-dimer was detected by a quantitative immunoturbidimetric assay. The normal value is 0.2-0.7 mg/L fibrinogen equivalent units (FEUs). During the year of 2009, 1,053 D-dimer tests were performed. We analyzed the results of these patients to find out the causes of very high D-dimer. The mean value of D-dimer in the 1,053 tests was 8.56 mg/L FEU, ranging from <0.2 mg/L to 563.2 mg/L FEU. Of them, 28 samples from 21 patients had very high D-dimer value: >50 mg/L FEU. Of the 21 patients, 9 (43%) had TED, 1 had suspected TED, but not proved by computed tomographic (CT) angiogram, 3 had massive gastrointestinal or other site bleeding, 3 patients had cardiac arrest with samples taken immediately after recovery from cardiopulmonary resuscitation (CPR), 2 had sepsis with disseminated intravascular coagulation (DIC), 1 had postpartum hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome with acute pulmonary edema and renal failure, 1 had multiple traumatic injury, and 1 received thrombolytic therapy. Although TED was the most frequently seen disorder in patients with very high D-dimer value, very high D-dimer was not necessary exclusively the marker of TED. Other disorders such as massive bleeding, status post CPR, sepsis with DIC, multiple traumatic injuries, hyperfibrinolysis and HELLP syndrome can also have very high D-dimer. Copyright © 2011.

Preeclampsia and HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome are pregnancy-related complications with high rates of morbidity and mortality. HELLP syndrome, in particular, can be difficult to diagnose. Recent work suggests that elevated levels of free cell hemoglobin in blood plasma can, as early as the first trimester, potentially serve as a diagnostic biomarker for impending complications. We therefore developed a point-of-care mobile phone-based platform that can quickly characterize a patient's level of hemolysis by measuring the color of blood plasma. The custom hardware and software are designed to be easy to use. A sample of the whole blood (~10µL or less) is first collected into a clear capillary tube or microtube, which is then inserted into a low-cost 3D-printed sample holder attached to the phone. A 5-10min period of quiescence allows for gravitational sedimentation of the red blood cells, leaving a layer of yellowish plasma at the top of the tube. The phone camera then photographs the capillary tube and analyzes the color components of the cell-free plasma layer. The software converts these color values to a concentration of free hemoglobin, based on a built-in calibration curve, and reports the patient's hemolysis level: non-hemolyzed, slightly hemolyzed, mildly hemolyzed, frankly hemolyzed, or grossly hemolyzed.. The accuracy of the method is ~1mgdL -1 . This phone-based point-of-care system provides the potentially life-saving advantage of a turnaround time of about 10min (versus 4+hours for conventional laboratory analytical methods) and a cost of approximately one dollar USD (assuming you have the phone and the software are already available).

[The neglected control of proteinuria during pregnancy].

PubMed

Dijkman, A; van Roosmalen, J

2002-03-02

In two women, primigravidae aged 29 and 27 years, no dipstick test for proteinuria was carried out despite symptoms of preeclampsia at 34 5/7 and 25 5/7 weeks of pregnancy, respectively. Both babies died in utero. The women were treated in the intensive care unit; the first woman died due to 'haemolysis, elevated liver enzymes, low platelet count' (HELLP) syndrome, while the second woman was able to return home in a reasonable condition on antihypertensive medication. Dipstick tests for proteinuria should always be carried out in pregnant women with symptoms of preeclampsia in order to avoid the death and serious morbidity which can be associated with eclampsia.

The angiogenic factor ratio soluble Fms-kinase 1 (sFlt-1)/placental growth factor (PlGF) is a novel diagnostic tool for preeclampsia. We compared the efficacy of the KRYPTOR (BRAHMS) automated assays for sFlt-1 and PlGF with the Elecsys (Roche) assays in a routine clinical setting. Preeclamptic women (n = 39) were included shortly after the time of diagnosis. Normotensive control pregnancies were matched by gestational age (n = 76). The KRYPTOR assays performed comparably or superior to Elecsys (sFlt-1/PlGF area under the curve 0.746 versus 0.735; P = .09; for non-obese 0.820 versus 0.805, P = .047). For early-onset preeclampsia, KRYPTOR area under the curve increased to 0.929 with a 100% specificity for preeclampsia at cut-off 85 and an 88.9% sensitivity for preeclampsia at cut-off 33. For women with preeclampsia and preterm delivery or Hemolysis, Elevated Liver enzymes, Low Platelet count (HELLP) syndrome, the KRYPTOR sFlt-1/PlGF ratio was manifold increased (P < .01). The sFlt-1/PlGF ratio proved especially useful in early-onset preeclampsia, preeclampsia with preterm delivery or HELLP, and among non-obese women. Copyright © 2015 American Society of Hypertension.

Gestational hypertension (GH) and pre-eclampsia (PE) can result in severe complications such as eclampsia, placental abruption, syndrome of Hemolysis, Elevated Liver enzymes and Low Platelets (HELLP) and ultimately even neonatal or maternal death. We recently showed that in women with GH or mild PE at term induction of labour reduces both high risk situations for mothers as well as the caesarean section rate. In view of this knowledge, one can raise the question whether women with severe hypertension, pre-eclampsia or deterioration chronic hypertension between 34 and 37 weeks of gestation should be delivered or monitored expectantly. Induction of labour might prevent maternal complications. However, induction of labour in late pre-term pregnancy might increase neonatal morbidity and mortality compared with delivery at term. Pregnant women with severe gestational hypertension, mild pre-eclampsia or deteriorating chronic hypertension at a gestational age between 34+0 and 36+6 weeks will be asked to participate in a multi-centre randomised controlled trial. Women will be randomised to either induction of labour or expectant monitoring. In the expectant monitoring arm, women will be induced only when the maternal or fetal condition detoriates or at 37+0 weeks of gestation. The primary outcome measure is a composite endpoint of maternal mortality, severe maternal complications (eclampsia, HELLP syndrome, pulmonary oedema and thromboembolic disease) and progression to severe pre-eclampsia. Secondary outcomes measures are respiratory distress syndrome (RDS), neonatal morbidity and mortality, caesarean section and vaginal instrumental delivery rates, maternal quality of life and costs. Analysis will be intention to treat. The power calculation is based on an expectant reduction of the maternal composite endpoint from 5% to 1% for an expected increase in neonatal RDS from 1% at 37 weeks to 10% at 34 weeks. This implies that 680 women have to be randomised. This trial will provide insight as to whether in women with hypertensive disorders late pre-term, induction of labour is an effective treatment to prevent severe maternal complications without compromising the neonatal morbidity.

Dewilde, Evelien; Huygens, Marc; Cools, Geertrui; Van Calster, Joachim

2014-01-01

Hypertensive retinopathy is well known, but choroidopathy is uncommon and associated with acute increases in blood pressure. Nonperfused areas of the choriocapillaris lead to changes of overlying retinal pigment epithelium (RPE), resulting in neurosensory or RPE detachments. The authors describe two patients with serous retinal detachments associated with acute arterial hypertension in pre-eclampsia and HELLP (hemolysis, elevated liver enzyme levels, and low platelet count) syndrome. Subretinal fluid was demonstrated on ultra-widefield fundus imaging and optical coherence tomography. Fluorescein angiography and indocyanine green angiography enabled imaging of the choroidal hypoperfusion. All signs and symptoms resolved after 1 and 3 months, respectively, with persistent macular pigmentary changes in both patients. Copyright 2014, SLACK Incorporated.

Comparison of referral and non-referral hypertensive disorders during pregnancy: an analysis of 271 consecutive cases at a tertiary hospital.

This retrospective cohort study analyzed the clinical manifestations in patients with preeclampsia and eclampsia, assessed the risk factors compared to the severity of hypertensive disorders on maternal and perinatal morbidity, and mortality between the referral and non-referral patients. 271 pregnant women with preeclampsia and eclampsia were assessed (1993 to 1997). Chi-square analysis was used for the comparison of categorical variables, and the comparison of the two independent variables of proportions in estimation of confidence intervals and calculated odds ratio of the referral and non-referral groups. Multivariate logistic regression was used for adjusting potential confounding risk factors. Of the 271 patients included in this study, 71 (26.2%) patients were referrals from other hospitals. Most of the 62 (87.3%) referral patients were transferred during the period 21 and 37 weeks of gestation. Univariate analysis revealed that referral patients with hypertensive disorder were significantly associated with SBP > or =180, DBP > or =105, severe preclampsia, haemolysis, elevated liver enzymes, low platelets (HELLP), emergency C/S, maternal complications, and low birth weight babies, as well as poor Apgar score. Multivariate logistic regression analyses revealed that the risk factors identified to be significantly associated with increased risk of referral patients included: diastolic blood pressure above 105 mmHg (adjusted odds ratio, 2.09; 95 percent confidence interval, 1.06 to 4.13; P = 0.034), severe preeclampsia (adjusted odds ratio, 3.46; 95 percent confidence interval, 1.76 to 6.81; P < 0.001), eclampsia (adjusted odds ratio, 2.77; 95 percent confidence interval, 0.92 to 8.35; P = 0.071), HELLP syndrome (adjusted odds ratio, 18.81; 95 percent confidence interval, 2.14 to 164.99; P = 0.008). The significant factors associated with the referral patients with hypertensive disorders were severe preeclampsia, HELLP, and eclampsia. Lack of prenatal care was the major avoidable factor found in referral and high risk patients. Time constraints relating to referral patients and the appropriateness of patient-centered care for patient safety and better quality of health care need further investigation on national and multi-center clinical trials.

Innate Immune System at the Maternal-Fetal Interface: Mechanisms of Disease and Targets of Therapy in Pregnancy Syndromes.

2016-10-01

The maternal-fetal interface is an immunologically unique site that allows the tolerance to the allogenic fetus and maintains host defense against possible pathogens. Balanced immune responses are required for the maintenance of successful pregnancy. It has been demonstrated that innate immune disturbances may be responsible for some adverse pregnancy outcomes such as preeclampsia (PE); hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome; intrauterine growth restriction (IUGR); and recurrent spontaneous abortion (RSA). Observational studies suggest that immunomodulatory treatments in pregnancy-specific complications may improve both the hematological/biochemical features in the mother and the perinatal outcomes. The following review will discuss how recent and relevant findings in the field of the innate immunity have advanced our understanding of the role of inflammation and innate immune system in the pathogenesis of pregnancy failure and will discuss the therapeutic outcomes of the existing studies and clinical trials in light of these new insights. © 2016 John Wiley & Sons A/S.

Regional anesthesia in patients with pregnancy induced hypertension

PubMed Central

Ankichetty, Saravanan P; Chin, Ki Jinn; Chan, Vincent W; Sahajanandan, Raj; Tan, Hungling; Grewal, Anju; Perlas, Anahi

2013-01-01

Pregnancy induced hypertension is a hypertensive disorder, which occurs in 5% to 7% of all pregnancies. These parturients present to the labour and delivery unit ranging from gestational hypertension to HELLP syndrome. It is essential to understand the various clinical conditions that may mimic preeclampsia and the urgency of cesarean delivery, which may improve perinatal outcome. The administration of general anesthesia (GA) increases morbidity and mortality in both mother and baby. The provision of regional anesthesia when possible maintains uteroplacental blood flow, avoids the complications with GA, improves maternal and neonatal outcome. The use of ultrasound may increase the success rate. This review emphasizes on the regional anesthetic considerations when such parturients present to the labor and delivery unit. PMID:24249977

The fibrinogen/CRP ratio as a new parameter for the diagnosis of disseminated intravascular coagulation in patients with HELLP syndrome and as a predictive factor for neonatal outcome.

PubMed

Windsperger, Karin; Lehner, Rainer

2013-02-01

The aim of this study was to determine if the fibrinogen/C-reactive protein (CRP) ratio could be used in obstetrics as a predictor for a disseminated intravascular coagulation. One hundred eleven patients with hemolysis, elevated liver enzymes, and low platelet count syndrome at the Department of Obstetrics and Fetomaternal Medicine (General Hospital, Vienna, Austria) were selected and divided into 2 groups (overt disseminated intravascular coagulation, no overt disseminated intravascular coagulation). The classical parameters and the fibrinogen/CRP ratio were compared. The analysis was carried out using IBM SPSS statistical package (SPSS, Inc, Cary, NC). The fibrinogen/CRP ratio showed significant differences. The receiver-operating characteristic analysis showed for the ratio (area under the curve, 0.74) significantly better discriminative power than for fibrinogen (area under curve, 0.59). The odds ratio for the fibrinogen/CRP ratio was 7.04. Finally, significant correlations between the ratio and the neonatal outcome were found. We suggest the implementation of the fibrinogen/CRP ratio within patients with hemolysis, elevated liver enzymes, and low platelet count syndrome as a diagnostic and prognostic factor for the occurrence of disseminated intravascular coagulation.

We present the case of a 33-year-old woman in her first pregnancy. She presented with pruritus at 34 weeks gestation. A diagnosis of intrahepatic cholestasis of pregnancy was made based on elevated bile acids and elevated liver transaminases. She re-presented 4 days later, jaundiced with abdominal pain and nausea, and was hypertensive. Her bilirubin was now elevated and her creatinine had doubled. The differential diagnosis-included pre-eclampsia and Hemolysis Elevated Liver enzymes Low Platelet count (HELLP) syndrome, and delivery was expedited. Postnatally, the patient became coagulopathic, though not thrombocytopaenic; she had persistent hypoglycaemia, hyponatraemia, developed acute pancreatitis and had profound ascites and peripheral oedema. Management was supportive with multidisciplinary care and over a period of 3 weeks she made a full clinical and biochemical recovery. PMID:25878236

2015-11-01

Preeclampsia complicates 2-8% of all pregnancies. Studies on the association of preeclampsia with thrombophilia are conflicting. Clinical heterogeneity of the disease may be one of the explanations. The present study addresses the question whether different phenotypes of preeclampsia are associated with thrombophilia factors. Study design We planned a retrospective cohort study. From 1985 until 2010 women with preeclampsia were offered postpartum screening for the following thrombophilia factors: anti-phospholipid antibodies, APC-resistance, protein C deficiency and protein S deficiency, hyperhomocysteineamia, factor V Leiden and Prothrombin gene mutation. Hospital records were used to obtain information on phenotypes of the preeclampsia and placental histology. We identified 844 women with singleton pregnancies who were screened for thrombophilia factors. HELLP complicated 49% of pregnancies; Fetal growth restriction complicated 61% of pregnancies. Early delivery (<34th week) occurred in 71% of pregnancies. Any thrombophilia factor was present in 29% of the women. Severe preeclampsia was associated with protein S deficiency (p=0.01). Fetal growth restriction was associated with anti-phospholipid antibodies (p<0.01). Early onset preeclampsia was associated with anti-phospholipid antibodies (p=0.01). Extensive placental infarction (>10%) was associated with anti-phospholipid antibodies (p<0.01). Low placental weight (<5th percentile) was associated with hyperhomocysteineamia (p=0.03). No other associations were observed. Early onset preeclampsia, especially if complicated by fetal growth restriction, are associated with anti-phospholipid antibodies. Other phenotypes of preeclampsia, especially HELLP syndrome, were not associated with thrombophilia. We advise only to test for anti-phospholipid antibodies after early onset preeclampsia, especially if complicated by fetal growth restriction. We suggest enough evidence is presented to justify no further studies are needed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The May-Hegglin anomaly is an inherited disorder, so uncommon that the incidence is still unknown. It is characterized by macro-thrombocytopenia with normal platelet function and cytoplasmic inclusion bodies in granulocytes. The case is reported of a 28-year-old primiparous patient who had an urgent caesarean section due to failed induction of labour. The patient had no history of abnormal bleeding. Other causes of thrombocytopenia or platelet dysfunction, such as preeclampsia, HELLP syndrome, or placental abruption, were ruled out. The platelet count prior to surgery was 20,900/mm(3) with normal platelet function. General anaesthesia was performed. No excessive bleeding occurred and a platelet transfusion was not needed.

Diabetes insipidus is an uncommon pathology; its incidence varies from two to six cases in 100,000 pregnancies. It has multiple etiologies and it is classified in central and neurogenic. Patients with diabetes insipidus generally show intense thirst, polyuria, neurologic symptoms and hypernatremia. It does not seem to alter the patient's fertility. Diabetes insipidus is usually associated with pre-eclampsia, HELLP syndrome, and fatty liver disease of pregnancy. This is a report of a case seen at the Hospital General de Cholula, in Puebla, Mexico. A 19 year-old female, with 37.2 weeks of pregnancy, had a history of Langerhans cell histiocytosis since she was four years. Patient was treated with intranasal desmopressin until 2005. She went to an obstetric evaluation; laboratory and cabinet studies were obtained. A healthy 1900 g female was obtained through vaginal delivery, with a 7/9 Apgar score. We should be familiarized with this uncommon pathology because of its association with several obstetric emergencies.

Acute renal failure in pregnancy: our experience.

Aggarwal, Rohina S; Mishra, Vineet V; Jasani, Anil F; Gumber, Manoj

2014-03-01

Acute renal failure (ARF) is a serious medical complication during pregnancy, and, in the post-partum period, is associated with significant maternal morbidity and mortality as well as fetal loss. The objective of our study is to find the etiology and maternal outcome of ARF during pregnancy. The study was conducted at the Obstetrics and Gynecology Department of the Institute of Kidney Disease and Research Center, Ahmedabad, India from January 2009 to January 2011. Fifty previously healthy patients who developed ARF, diagnosed on oliguria and serum creatinine >2 mg%, were included in the study. Patients with a known history of renal disease, diabetes and hypertension were excluded from the study. All patients were followed-up for a period of six months. Patient re-cords, demographic data, urine output on admission and preceding history of antepartum hemorrhage (APH), post-partum hemorrhage (PPH), septicemia, operative interventions and retained product of conception were noted and need for dialysis was considered. Patients were thoroughly examined and baseline biochemical investigations and renal and obstetrical ultrasound were performed on each patient and bacterial culture sensitivity on blood, urine or vaginal swabs were performed in selected patients. The age range was 19-38 years (mean 26 ± 3.8). The first trimester, second trimester and puerperal groups comprised of four (8%), 25 (50%) and 21 patients (42%), respectively. Hemorrhage was the etiology for ARF in 15 (30%), APH in ten (20%) and PPH in five (10%) patients. Eleven (22%) patients had lower segment cesarian section (LSCS) while 36 (78%) patients had normal vaginal delivery. In 20 (40%) patients, puerperal sepsis was the etiological factor, while pre-eclampsia, eclampsia and HELLP syndrome accounted for 18 (36%) patients. Two (4%) patients had disseminated intravascular coagulation on presentation while one (2%) patient was diagnosed with hemolytic uremic syndrome. Maternal mortality was 12% (n = 6). Of the 38 (88%) surviving patients, 21 (42%) had complete recovery of renal function, eight (16%) patients had partial and 15 (30%) patients required dialysis on a long-term basis. ARF in pregnancy is associated with poor maternal and renal outcome if not detected and treated in time.

Study of Abnormal Liver Function Test during Pregnancy in a Tertiary Care Hospital in Chhattisgarh.

2016-10-01

Abnormal liver function tests (LFTs) in pregnancy require proper interpretation in order to avoid pitfalls in the diagnosis. The underlying disorder can have a significant effect on the outcome of both mother and foetus. The present study was done with the objective to study the clinical profile, incidence and possible causes of derangements of liver function tests. Eighty pregnant women with abnormal liver dysfunction were studied prospectively. Women with chronic liver disease and drug-induced abnormal liver function test were excluded. All available LFTs including LDH were studied along with some more definitive tests to aid identification of underlying cause. Foetomaternal outcome was noted in all. The incidence of abnormal LFT was 0.9 %. 13/80 (16.75 %) women had liver disorder not specific to pregnancy, whereas 67/80 (83.25 %) women had pregnancy-specific liver dysfunction. Of these, 65(81.25 %) women with liver dysfunction had pre-eclampsia including 11 (13.75 %) with HELLP and six women with eclampsia. 48/65 (60 %) women had pre-eclampsia in the absence of HELLP syndrome or eclampsia. The mean value for bilirubin (mg %) in hypertensive disorders of pregnancy ranged from 1.64 to 3.8, between 5 and 10 for ICP and AFLP and >10 in infective hepatitis. Transaminases were highest in infective hepatitis, whereas alkaline phosphate was highest in ICP. Total 27 (33.75 %) women suffered from adverse outcome with four (5 %) maternal deaths and 23 (28.75 %) major maternal morbidities. 33/80 (41.25 %) women had intrauterine death. 26.25 % babies were small for date. Pregnancy-specific disorders are the leading cause of abnormal liver function test during pregnant state particularly in the third trimester. Pre-eclampsia-related disorder is the commonest. Gestational age of pregnancy and relative values of various liver function tests in different pregnancy-specific and pregnancy nonspecific disorders appear to be the best guide to clinch the diagnosis.

Posterior reversible encephalopathy syndrome (PRES) is associated with variable predisposing risk factors including preeclampsia and eclampsia since it proposed. However, studies of large case series focusing on pregnancy-related PRES are still limited. We performed a large retrospective study of patients with pregnancy-related PRES admitted to our institution. This was a single-center, 2010-2015 retrospective cohort study of patients with pregnancy-related PRES who underwent neuroimaging via magnetic resonance imaging or computerized tomography from mainland China. 26 of 28 women with eclampsia and 7 of 59 women with preeclampsia had confirmed PRES. A total of 36 patients were finally included as confirmed pregnancy-related PRES in this research. Acute hypertension was present in 31 patients (86%). Headache was the most common presenting symptom (81%) followed by seizures (73%), altered mental status (57%), nausea/vomiting (47%) and visual disturbance (33%). Atypical involved regions included frontal lobe (72%), temporal lobe (67%), basal ganglia (50%), cerebellum (47%), brain stem (14%) and thalamus (8%). Atypical neuroimaging features included restricted diffusion (33%), contrast enhancement (19%) and hemorrhage (19%). Comorbidities included thrombocytopenia (25%), pulmonary infection (25%), anemia (19%), fever (17%), acute renal failure (8%), HELLP syndrome (6%), DIC (6%). Most of patients recovered completely with timely diagnosis and treatment. Two patients who suffered DIC finally died. Patients with pregnancy-related PRES may present with atypical neuroimaging findings. Moreover, our data supported the view that nearly all imaged patients with eclampsia had clinical and radiologic findings of PRES.

Acute Kidney Injury in Pregnancy.

PubMed

Jim, Belinda; Garovic, Vesna D

2017-07-01

Pregnancy-related acute kidney injury (AKI) has declined in incidence in the last three decades, although it remains an important cause of maternal and fetal morbidity and mortality. Pregnancy-related causes of AKI such as preeclampsia, acute fatty liver of pregnancy, HELLP (Hemolysis, Elevated Liver function tests, Low Platelets) syndrome, and the thrombotic microangiopathies (thrombotic thrombocytopenic purpura, atypical hemolytic-uremic syndrome [HUS]) exhibit overlapping features and often present as diagnostic dilemmas. Differentiating among these conditions may be difficult or impossible based on clinical criteria only. In difficult and rare cases, a renal biopsy may need to be considered for the exact diagnosis and to facilitate appropriate treatment, but the risks and benefits need to be carefully weighed. The use of eculizumab for the treatment of atypical HUS has demonstrated efficacy in early case reports. Non-pregnancy related causes such as volume depletion and pyelonephritis require early and aggressive resuscitative as well as antibiotic measures respectively. We will discuss in this review the various etiologies of AKI in pregnancy, current diagnostic approaches, and the latest treatment strategies. Given the recent trends of increasing maternal age at the time of pregnancy, and the availability of modern reproductive methods increase the risks of AKI in pregnancy in the coming years.

Thrombophilia and pregnancy complications: cause or association?

PubMed

Middeldorp, S

2007-07-01

Both acquired and inherited thrombophilia is associated with an increased risk of pregnancy failure (i.e. sporadic and recurrent miscarriage, late fetal loss), as well as hypertensive pregnancy complications such as pre-eclampsia and HELLP syndrome. The question of whether this relationship can be considered causal is rather philosophical. For practical purposes, the consistency and strengths of associations, potential mechanisms and, most importantly, the possibility to intervene with anticoagulants are reviewed. Relevant methodological issues in the case of thrombophilia and pregnancy complications consist of differences between observational and experimental research and quality issues in randomized controlled trials. The mechanisms associating thrombophilia and pregnancy complications are likely to involve effects on trophoblast differentiation rather than mere hypercoagulability. Therapeutic options comprise aspirin as well as (low molecular weight) heparin. For women with antiphospholipid antibody syndrome, this treatment is often suggested although the evidence is limited. For women with inherited thrombophilia and unexplained recurrent pregnancy loss, at present there is no evidence supporting treatment. Observational research is hampered by severe methodological flaws or inconsistent results. Two published randomized trials have not used an adequate comparator (i.e. no treatment or placebo). Currently, randomized controlled trials with no treatment or placebo are being carried out and results should be awaited before implementing a potentially harmful intervention in pregnant women with inherited thrombophilia and a history of pregnancy complications.

Women's Experiences of Preeclampsia: Australian Action on Preeclampsia Survey of Women and Their Confidants

East, C.; Conway, K.; Pollock, W.; Frawley, N.; Brennecke, S.

2011-01-01

Introduction. The experience of normal pregnancy is often disrupted for women with preeclampsia (PE). Materials and Methods. Postal survey of the 112 members of the consumer group, Australian Action on Pre-Eclampsia (AAPEC). Results. Surveys were returned by 68 women (61% response rate) and from 64 (57%) partners, close relatives or friends. Respondents reported experiencing pre-eclampsia (n = 53), eclampsia (n = 5), and/or Hemolysis, Elevated Liver enzymes, and Low Platelets (HELLP syndrome) (n = 26). Many women had no knowledge of PE prior to diagnosis (77%) and, once diagnosed, did not appreciate how serious or life threatening it was (50%). Women wanted access to information about PE. Their experience contributed substantial anxiety towards future pregnancies. Partners/friends/relatives expressed fear for the woman and/or her baby and had no prior understanding of PE. Conclusions. The PE experience had a substantial effect on women, their confidants, and their babies and affected their approach to future pregnancies. Access to information about PE was viewed as very important.

Pregnancy outcome in women with polycystic ovary syndrome comparing the effects of laparoscopic ovarian drilling and clomiphene citrate stimulation in women pre-treated with metformin: a retrospective study

PubMed Central

2010-01-01

Background Ovarian stimulation in women with polycystic ovary syndrome (PCOS) increases the risk for perinatal complications. Ovulation induction by laparoscopic ovarian drilling (LOD) might improve the overall pregnancy outcomes. The aim of our study was to assess the adverse events or effects on pregnancy of LOD and clomiphene citrate (CC) stimulation in patients who received metformin. Methods Setting: Academic research institution. We retrospectively analyzed the courses of 40 spontaneous pregnancies after LOD for CC-resistance, 40 pregnancies after CC stimulation, and 40 pregnancies after metformin treatment alone. Patients in the LOD and the CC groups had been pre-treated with Metformin. Primary outcome parameters were: the rate of multiple pregnancies; the rate of early pregnancy losses/miscarriages; the development of gestational diabetes, pregnancy-induced hypertension, and preeclampsia/HELLP-syndrome; premature delivery; and birth weight. Results The rate of twin pregnancies did not differ between the CC group (12.5%), the LOD group (7.5%), and the metformin only group (2.5%, p = 0.239). Seventeen women suffered an early miscarriage. There were no differences with regard to the rates of gestational diabetes, pregnancy-induced hypertension, preeclampsia, and preterm delivery. By analyzing all pregnancy complications together, the overall pregnancy complication rate was highest in the CC group (70.0%, 28/40), followed by the LOD group (45.0%, 18/40), and the metformin only group (47.5%, 19/40; p = 0.047). Conclusions CC, but not LOD, increases the complication rate in pregnant patients who received metformin. PMID:20465786

Ovarian stimulation in women with polycystic ovary syndrome (PCOS) increases the risk for perinatal complications. Ovulation induction by laparoscopic ovarian drilling (LOD) might improve the overall pregnancy outcomes. The aim of our study was to assess the adverse events or effects on pregnancy of LOD and clomiphene citrate (CC) stimulation in patients who received metformin. Academic research institution. We retrospectively analyzed the courses of 40 spontaneous pregnancies after LOD for CC-resistance, 40 pregnancies after CC stimulation, and 40 pregnancies after metformin treatment alone. Patients in the LOD and the CC groups had been pre-treated with Metformin. Primary outcome parameters were: the rate of multiple pregnancies; the rate of early pregnancy losses/miscarriages; the development of gestational diabetes, pregnancy-induced hypertension, and preeclampsia/HELLP-syndrome; premature delivery; and birth weight. The rate of twin pregnancies did not differ between the CC group (12.5%), the LOD group (7.5%), and the metformin only group (2.5%, p=0.239). Seventeen women suffered an early miscarriage. There were no differences with regard to the rates of gestational diabetes, pregnancy-induced hypertension, preeclampsia, and preterm delivery. By analyzing all pregnancy complications together, the overall pregnancy complication rate was highest in the CC group (70.0%, 28/40), followed by the LOD group (45.0%, 18/40), and the metformin only group (47.5%, 19/40; p=0.047). CC, but not LOD, increases the complication rate in pregnant patients who received metformin.

Objective: Lipids and steroid hormones are closely linked. While cholesterol is the substrate for (placental) steroid hormone synthesis, steroid hormones regulate hepatic lipid production. The aim of this study was to quantify circulating steroid hormones and lipid metabolites, and to characterize their interactions in normal and pathological pregnancies with a focus on hepatic and placental pathologies. Methods: A total of 216 serum samples were analyzed. Group A consisted of 32 patients with uncomplicated pregnancies who were analyzed at three different time-points in pregnancy (from the first through the third trimester) and once post partum. Group B consisted of 36 patients (24th to 42nd week of gestation) with pregnancy pathologies (IUGR n = 10, preeclampsia n = 13, HELLP n = 6, intrahepatic cholestasis n = 7) and 31 controls with uncomplicated pregnancies. Steroid profiles including estradiol, progesterone, and dehydroepiandrosterone were measured by GC-MS and compared with lipid concentrations. Results: In Group A, cholesterol and triglycerides correlated positively with estradiol (cholesterol ρ = 0.50, triglycerides ρ = 0.57) and progesterone (ρ = 0.49, ρ = 0.53) and negatively with dehydroepiandrosterone (ρ = − 0.47, ρ = − 0.38). Smoking during pregnancy affected estradiol concentrations, leading to lower levels in the third trimester compared to non-smoking patients (p < 0.05). In Group B, cholesterol levels were found to be lower in IUGR pregnancies and in patients with HELLP syndrome compared to controls (p < 0.05). Steroid hormone concentrations of estradiol (p < 0.05) and progesterone (p < 0.01) were lower in pregnancies with IUGR. Discussion: Lipid and steroid levels were affected most in IUGR pregnancies, while only minor changes in concentrations were observed for other pregnancy-related disorders. Each of the analyzed entities displayed specific changes. However, since the changes were most obvious in pregnancies complicated by IUGR and only minor changes were observed in pregnancies where patients had impaired liver function, our data suggests that placental rather than maternal hepatic function strongly determines lipid and steroid levels in pregnancy.

Given the expression of ABO blood group antigens on the surface of a wide range of human cells and tissues, the putative interplay of the ABO system in human biology outside the area of transfusion and transplantation medicine constitutes an intriguing byway of research. Thanks to evidence accumulated over more than 50 years, the involvement of the ABO system in the pathogenesis of several human diseases, including cardiovascular, infectious and neoplastic disorders, is now acknowledged. However, there is controversial information on the potential association between ABO blood type and adverse pregnancy outcomes, including pre-eclampsia and related disorders (eclampsia, HELLP syndrome and intrauterine growth restriction), venous thromboembolism, post-partum haemorrhage and gestational diabetes. To elucidate the role of ABO antigens in pregnancy-related complications, we performed a systematic review of the literature published in the past 50 years. A meta-analytical approach was also applied to the existing literature on the association between ABO status and pre-eclampsia. The results of this systematic review are presented and critically discussed, along with the possible pathogenic implications. PMID:27177402

A Brief Overview of Preeclampsia

Preeclampsia (PE) is a leading cause of maternal mortality and morbidity worldwide. It occurs in women with first or multiple pregnancies and is characterized by new onset hypertension and proteinuria. Improper placentation is mainly responsible for the disease. If PE remains untreated, it moves towards more serious condition known as eclampsia. Hypertension, diabetes mellitus, proteinuria, obesity, family history, nulliparity, multiple pregnancies and thrombotic vascular disease contribute as the risk factors for PE. PE triggered metabolic stress causes vascular injury, thus contributing to the development of cardiovascular disease (CVD) and/or chronic kidney disease (CKD) in future. This risk appears to be increased especially in women with a history of recurrent PE and eclampsia. Clinically increased serum levels of sFlt-1 and decreased placental growth factor (PIGF) and vascular endothelial growth factor (VEGF) represent the severe condition of PE. The clinical findings of sever PE are assorted by the presence of systemic endothelial dysfunction, microangiopathy, the liver (hemolysis, elevated liver function tests and low platelet count, namely HELLP syndrome) and the kidney (proteinuria). The early detection of PE is one of the most important goals in obstetrics. PMID:24400024

The incidence and cause of strokes associated with pregnancy and the puerperium are still not fully understood. The aim of this study was to characterize pregnancy-related strokes in Japan using a large-scale survey with current imaging techniques. A retrospective analysis was conducted based on clinical chart reviews in 736 stroke teaching hospitals certified by the Japan Stroke Society between 2012 and 2013, using a web-based questionnaire requesting the detailed clinical course without any personally identifying information. The collection rate of this questionnaire was 70.5%, with 151 pregnancy-associated strokes extracted. Hemorrhagic strokes were observed in 111 cases (73.5%), ischemic strokes in 37 (24.5%), and mixed type in 3 cases (2.0%). The estimated incidence of pregnancy-associated stroke was 10.2 per 100 000 deliveries. Major causes of hemorrhage were aneurysm (19.8%), arteriovenous malformation (17.1%), pregnancy-induced hypertension (11.7%), and HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count) (8.1%). Preexisting cerebrovascular diseases responsible for hemorrhage were detected in 59 cases (53.1%). Among the ischemic strokes, 28 (75.7%) were arterial and 9 (24.3%) were venous infarctions. The most frequent cause of arterial infarctions was reversible cerebral vasoconstriction syndrome. Hemorrhagic stroke showed much poorer prognosis than ischemic stroke. The incidence of pregnancy-associated stroke in Japan did not seem higher than that in other Asian and Western countries. The proportion of hemorrhagic stroke among Japanese women was much higher than that in white women. Preexisting cerebrovascular diseases and reversible cerebral vasoconstriction syndrome play a key role in hemorrhagic and ischemic stroke, respectively. © 2016 American Heart Association, Inc.

Authors in the article describe a case of a patient with thrombotic thrombocytopenic purpurain 37 weeks gestation complicated by acute severe hemorrhagic-necrotic pancreatitis during the early puerperium. Case report. Ist Department of gynaecology and obstetrics of the Comenius University Bratislava. 33-years-old patient in the 37 weeks gestation was admitted to our department with the signs of HELLP syndrome (hemolysis, elevated liver enzymes, low platelets). Due to the worsening clinical status, we have performed caesarean section. After the transient stabilization of the patient's clinical status, the hemolysis with severe thrombocytopenia reappeared. Based on the clinical signs of abdominal pain and computer tomography, the diagnosis of acute hemorrhagic-necrotic pancreatitis was set. The primary diagnosis was thrombotic thrombocytopenic purpura. Therefore, therapeutic plasma exchange was performed with consequent improvement of the patients clinical state. Normalization of the platelet count was achieved after 4.plasma exchanges. Consequently 5 plasma exchanges were performed. However, one month later, the disease relapsed. Therapeutic plasma exchanges were needed again (4x), with anti CD 20 administration. This therapy had good clinical outcome, without the need for further plasma exchanges. Thrombotic thrombocytopenic purpura is highly lethal disease. Early diagnosis, treatment, and multidisciplinary approach are essential.

Pregnancy induces a number of physiologic changes that affect the hematologic indices, either directly or indirectly. Recognizing and treating hematologic disorders that occur during pregnancy is difficult owing to the paucity of evidence available to guide consultants. This paper specifically reviews the diagnosis and management of benign hematologic disorders occurring during pregnancy. Anemia secondary to iron deficiency is the most frequent hematologic complication and is easily treated with oral iron formulations,; however care must be taken not to miss other causes of anemia, such as sickle cell disease. Thrombocytopenia is also a common reason for consulting the hematologist and distinguishing gestational thrombocytopenia from immune thrombocytopenia (ITP), preeclampsia, HELLP syndrome, or thrombotic thrombocytopenic purpura (TTP) is essential since the treatment differs widely. Occasionally the management of mother and infant involves the expeditious recognition of neonatal alloimmune thrombocytopenia (NAIT), a condition that is responsible for severe life-threatening bleeding of the newborn. Additionally, inherited and acquired bleeding disorders affect pregnant women disproportionately and often require careful monitoring of coagulation parameters in order to prevent bleeding in the puerperium. Finally, venous thromboembolism (VTE) during pregnancy is still largely responsible for mortality during pregnancy and the diagnosis, treatment options and guidelines for prevention of VTE during pregnancy are explored.

The hepatic hematoma or rupture appear in 1 of every 100,000 pregnancies. The most common causes of hepatic hematoma in pregnancy are severe preeclampsia and HELLP syndrome; some predisposing factors are seizures, vomiting, labor, preexistent hepatic disease and trauma. A 33 year old primigravid with a normal 33 week twin pregnancy presented abdominal pain and hypovolemic shock due to spontaneous subcapsular hepatic hematoma; laparoscopy was performed to evaluate the possibility of rupture, which was not found, later emergency cesarean section was carried out followed by hepatic hematoma drainage and abdominal packaging by laparoscopy. After surgery the flow through drainage was too high additionally hemodynamic instability and consumption coagulopathy. Abdominal panangiography was performed without identifying bleeding areas. Intesive care was given to the patient evolving satisfactorily, was discharged 19 days after the event. Seven months later she had laparoscopic cholecystectomy due to acute litiasic colecistitis. We found 5 cases in literatura about hepatic hematoma during pregnancy no related to hypertensive disorders of pregnancy; these were related to hepatoma, amebian hepatic abscess, falciform cell anemia, cocaine consumption and molar pregnancy. Hepatics hematomas have high morbidity and mortality so is significant early diagnosis and multidisciplinary approach.

To discuss the clinical features, management, pregnancy outcome and prognosis of obstetric mirror syndrome. The clinical data of 12 cases with obstetric mirror syndrome at Shenzhen Maternity and Child Healthcare Hospital from April 2008 to December 2010 were collected to retrospectively analyze the clinical features, management, pregnancy outcome and prognosis. (1) ETIOLOGY: 12 cases with obstetric mirror syndrome included 9 cases of Bart's hydrops fetalis, 2 cases with fetal complicated congenital cardiac anomalies, and 1 case of unknown etiology. (2) Gestational age at diagnosis and at delivery: gestational age at diagnosis ranged from 28 to 36 weeks [mean (31.5 ± 4.7) weeks], and gestational age at delivery ranged from 28(+3) to 38 weeks [mean (32.9 ± 2.9) weeks]. There were no significant differences between the gestational age at diagnosis and at delivery in consistence with severe preeclampsia group and mild preeclampsia group [(31.8 ± 2.3) weeks vs. (30.9 ± 7.2) weeks, (32.5 ± 2.3) weeks vs. (33.5 ± 3.9) weeks, P > 0.05]. (3) The patients with obstetric mirror syndrome can present a preeclampsia-like syndrome: maternal extremity edema in 12 cases, headache and visual disturbance in 1 case, proteinuria in 11 cases, elevated blood pressure in 5 cases, elevated uric acid in 9 cases, hypoproteinemia in 12 cases, elevated creatinine in 3 case, elevated liver enzyme in 1 case, thrombocytopenia in 2 cases. The major complications included 1 case of HELLP syndrome, acute pulmonary edema, placental abruption, amnionic fluid embolism, DIC respectively, 3 cases of acute kidney failure and 6 cases of postpartum hemorrhage. (4) Sonographic findings: 1) Hydrops fetalis: fetal ultrasound revealed pleural fluid, fetal ascites, skin edema, scalp edema, encephalocolele enlargement, hydropericardium and increased cardio-chest ratio. 2) Placenta megaly: the placental pathological examination revealed edematous and large in 12 cases. Placental thickness was beyond 4 cm in all cases [(6.3 ± 1.9) cm]. 3) Hydramnios: hydramnios could be found in 11 cases [amniotic fluid index (19.7 ± 3.1) cm]. (5) Postnatal conditions:all blood pressure and laboratory findings including urine protein normalized within 5 to 7 days after delivery. (6) Pregnancy outcome:all 12 patients survived, however the perinatal mortality rate was 100%. Two of 12 cases with mirror syndrome underwent cesarean section, and 10 were vaginal delivery, of which 1 need uterine artery embolisom due to postpartum hemorrhage. Obstetric mirror syndrome seems to simulate preeclampsia although there are distinguishing features, such as hemodilution, placental edema, and polyhydramnios. When the specific cause of obstetric mirror syndrome can not be identified and corrected, the decision for delivery should be made as soon as possibly.

Gestational hypertension (GH) and Preeclampsia, (PE) are the most complicated amongst hypertensive disorders of pregnancy. The mechanism that links hypertension in pregnancy to adverse maternal outcomes is not fully understood though some relate this to endothelial dysfunction originating from an imbalanced angiogenic regulators and oxidative stress biomarkers. This study assessed the correlation between angiogenic regulators and oxidative stress biomarker levels with adverse pregnancy outcomes among GH and PE participants. A cohort of pregnant women who received antenatal care at the Obstetrics and Gynaecology department of the Komfo Anokye Teaching Hospital (KATH) were followed. During their antenatal visits, 100 developed PE and 70 developed GE, of these, 50 PE and 50 GH gave informed consent. Their blood samples were taken at time of diagnosis and 48 h post-partum. 50 other aged-matched women who did not develop neither GH nor PE were selected as controls. Placental growth factor (PLGF), soluble fms-like tyrosine kinase 1 (sFlt-1) and 8-epi-prostaglandin F2alpha (8-epi-PGF2α) levels were estimated by ELISA and total antioxidant capacity (T-AOC) was measured spectrophotometrically. Graphpad Prism was used for data analysis. Median levels of sFlt-1, 8-epi-PGF2α and sFlt-1/PLGF were elevated among participants with PE co-existing with intrauterine fetal death (IUFD), placental abruptio, placental previa, HELLP syndrome and intrauterine growth restriction (IUGR) compared to PE without adverse outcomes (p = 0.041, p = 0.005, p = 0.0002). Levels of PLGF, T-AOC and PLGF/sFlt-1 were significantly reduced among participants with PE co-existing with IUFD, placental abruptio, placental previa, HELLP syndrome and IUGR compared to PE without adverse outcomes (p = 0.0013, p = 0.006, p < 0.0001). A significant negative correlation of IUGR (p = 0.0030; p < 0.0001), placental abruptio (p < 0.0001; p < 0.0001), IUFD (p < 0.0001; p < 0.0001), stillbirth (p = 0.0183 and p < 0.000), and postpartum haemorrhage (PPH) (p = 0.0420; p = 0.0044) were associated with both PLGF and T-AOC whilst a significant positive correlation of IUGR, placental abruptio (p < 0.0001; p < 0.0001), IUFD (p < 0.0001; p < 0.0001), stillbirth (p < 0.0001; p < 0.0001), and PPH (p = 0.0043; p = 0.0039) were observed with both sFlt-1 and 8-epi-PGF2α in PE. Imbalance in the levels of angiogenic regulators and oxidative stress biomarkers correlates with adverse pregnancy outcomes among PE participants. Early identification of these imbalance would alert health care givers in anticipation of adverse pregnancy outcome and thus increased surveillance during pregnancy and parturition and measures to ameliorate the adverse outcome.

To examine the relative importance of antenatal and perinatal variables on short- and long-term outcome of preterm growth restricted fetuses with umbilical artery (UA) Doppler abnormalities. This was a cohort study of 180 neonates with birth weight < 10(th) percentile, gestational age at delivery < 34 weeks and abnormal Doppler ultrasound examination of the UA. Various antenatal and perinatal variables were studied in relation to short- and long-term outcome. Neonatal and overall mortality (up to 2 years of age) were predicted by low gestational age at delivery. Neonatal mortality was additionally predicted by absent or reversed UA end-diastolic flow, while the presence of severe neonatal complications and placental villitis were additional predictors of both infant (between 28 days and 1 year of postnatal life) and overall mortality. Placental villitis was found to be the only predictor of necrotizing enterocolitis. Low gestational age at delivery, male sex, abnormal cardiotocography, absent or reversed UA end-diastolic flow and the HELLP syndrome predicted respiratory distress syndrome. Abnormal neurodevelopmental outcome at 2 years was predicted by low birth weight (< 2.3(rd) percentile), fetal acidosis (UA pH < 7.00), and placental villitis. Less advanced gestation at delivery remains an important predictor of short-term outcome in growth-restricted fetuses. In addition, the presence of placental villitis may aid neonatologists in the early identification of infants at increased risk of necrotizing enterocolitis, death and abnormal neurodevelopment at 2 years of age. Abnormal neurodevelopment was related to low weight and acidosis at birth, indicating that the severity of malnutrition and fetal acidosis affect long-term outcome.

Two cases are reported of familial partial trisomy 6q syndrome due to segregation of ins(5;6) (q33;q15q27) in three generations. The common clinical features include growth and mental retardation, feeding difficulty during infancy, microcephaly with downward slanting palpebral fissures, flattened nasal bridge with anteverted and flared nares, long philtrum, high arched palate, partially opened and protruding mouth with receding chin, deep transverse creases of the ears, three creases on the 4th fingers, clinodactyly of the 5th fingers with a single crease, and other dermatoglyphic findings. These characteristic features of two patients appear to make partial trisomy 6q a clinically recognizable syndrome.

Small for Size Syndrome (SFSS) syndrome is a recognizable clinical syndrome occurring in the presence of a reduced mass of liver, which is insufficient to maintain normal liver function. A definition has yet to be fully clarified, but it is a common clinical syndrome following partial liver transplantation and extended hepatectomy, which is characterized by postoperative liver dysfunction with prolonged cholestasis and coagulopathy, portal hypertension, and ascites. So far, this syndrome has been discussed with focus on the remnant size of the liver after partial liver transplantation or extended hepatectomy. However, the current viewpoints believe that the excessive flow of portal vein for the volume of the liver parenchyma leads to over-pressure, sinusoidal endothelial damages and haemorrhage. The new hypothesis declares that in both extended hepatectomy and partial liver transplantation, progression of Small for Size Syndrome is not determined only by the "size" of the liver graft or remnant, but by the hemodynamic parameters of the hepatic circulation, especially portal vein flow. Therefore, we suggest the term "Small for Size and Flow (SFSF)" for this syndrome. We believe that it is important for liver surgeons to know the pathogenesis and manifestation of this syndrome to react early enough preventing non-reversible tissue damages.

The pregnancies in systemic erythematous lupus (SLE) disease is a situation of high risk and involve both the mother and the fetus. The prematurity and the miscarriage are there more frequent, with increase risks of eclampsia, acute hypertension, HELP syndrome and of worsening renal disease. So the morbimortality is multiplied particularly when a anti-phospholipid syndrome 'APLS' is associated. The pregnancy remains however authorized when the SLE is in remission for more than 6 months with a validated treatment and successful means of monitoring. To review the clinical profile of the pregnancies at the SLE patients with or without APLS in Internal Medicine Practice. it's a retrospective study, in an internal medical centre over a period going from January, 2008 till December, 2011. The collection of the data is made from the index cards of clinical observations collecting items to interpret the data. All the patients are diagnosed referring to the criteria ACR (SLE/APLS) and all benefit from a follow-up in a obstetrics monitoring (ultrasounds to monitor growth and placental development). On a cohort of 80 SLE young patients hospitalized we brought together 20 patients answering eligibility criteria. The average age is of 26 years (21-41), SLE evolve with an average of 2.5years, the parity is estimated at 5 on average by patient. The pregnancies are programmed in only in 25% . The others cases of pregnancy remain the consequence of a not adapted contraception (50%). Lupus patients have history of renal damage (8) requiring immunosuppressive therapy (4) but renal function is preserved at all the patient's. The treatment is adapted to the clinical context and prophylactic doses of heparin and a baby aspirin are required in most situations. The cardiovascular and metabolic risk factors show an overweight (12), one dyslipemia (10), type 2 diabetes (2), and hypertension (3). The pregnancy is at the origin of a degradation of the renal function (4) with definitive chronic renal Insufficiency (1). The specific events observed are a HELLP syndrome (1), pre-eclampsia (2), fetal losses (5), ischemic strokes (4) and post-partum cardiomyopathy (1). The pregnancies require caesarians (15) with ligature of trunks (2). We deplore fetal deaths (7) in tripled (1) and in twin (1) during the period of follow-up. We note a small birth weight (7), a preterm birth (5), a foetal distress (5) at the origin of a psychomotor disorders (1) and we observed a case of a transient skin lupus (1). The frequency of the maternal and fetal complications is partially understandable by the fact that the majority of the pregnancies neither are programmed, nor authorized by the treating physician. Indeed, between the denial of the disease and the desire of pregnancy in everything taken, the patients often take the risk and put the treating physician in front of pregnancies in top risks.

Breast feeding is particularly important and difficult in children born prematurely, especially after hypertensive diseases in pregnancies (HDP). Therefore, we aimed to investigate breast feeding in women who developed HDP. Data on breast-feeding was collected within a nationwide research project on psychosocial factors in HDP. A self-administered questionnaire was given to 2600 women with a suspected history of HDP and 1233 controls. After matching and confirming diagnosis according to ISSHP criteria, 877 women with HDP and 623 controls were included into the study. Control women initiated (48.9/39.2%; P<0.001) and continued (42.2/37.2%; P<0.005) breast-feeding significantly more often than women with HDP. This holds particularly for women who developed HELLP syndrome (48.9/34.7%; P<0.0001, 42.2/33.5%; P<0.0001). A delivery before the 32(nd) gestational week (19.5/81.8%; P<0.0001) and a birth weight of less than 1500 g (18.8/75%; P<0.0001) were associated with the decision not to breast-feed. Women affected by HDP breast fed significantly less often than control women. This effect is at least partly caused by the increased rate of prematurity. Encouraging and supporting these women in breast-feeding is important to improve neonatal physical and mental development.

Pregnancy is a very strong trigger for acute disease manifestation in patients with hereditary TTP caused by double heterozygous or homozygous mutations of ADAMTS13 (ADisintegrin And Metalloprotease with ThromboSpondin type 1 domains, no. 13). In several affected women disease onset during their first pregnancy leads to the diagnosis of hereditary TTP. Without plasma treatment mother and especially fetus are at high risk of dying. The relapse risk during a next pregnancy is almost 100% but regular plasma transfusion starting in early pregnancy will prevent acute TTP flare-up and may result in successful pregnancy outcome. Pregnancy may also constitute a mild risk factor for the onset of acute acquired TTP caused by autoantibody-mediated severe ADAMTS13 deficiency. Women having survived acute acquired TTP may not be at very high risk of TTP relapse during an ensuing next pregnancy but seem to have an elevated risk of preeclampsia. Monitoring of ADAMTS13 activity and inhibitor titre during pregnancy may help to guide management and to avoid disease recurrence. Finally, TTP needs to be distinguished from the much more frequent hypertensive pregnancy complications, preeclampsia and especially HELLP (Hemolysis, Elevated Liver Enzymes, Low Platelet count) syndrome. © 2015 Elsevier Ltd.

Atypical HUS (aHUS) is a disorder most commonly caused by inherited defects of the alternative pathway of complement, or the proteins that regulate this pathway, and life-threatening episodes of aHUS can be provoked by pregnancy. We retrospectively and prospectively investigated 27 maternal and fetal pregnancy outcomes in 14 women with aHUS from the Vienna Thrombotic Microangiopathy Cohort. Seven pregnancies (26%) were complicated by pregnancy-associated aHUS (p-aHUS), of which three appeared to be provoked by infection, bleeding, and curettage, and three individuals were considered to have preeclampsia/HELLP syndrome before the definitive diagnosis of p-aHUS was made. Mutations in genes that encode the complement alternative pathway proteins or the molecules that regulate this pathway were detected in 71% of the women, with no relationship to pregnancy outcome. Twenty-one pregnancies (78%) resulted in a live birth, two preterm infants were stillborn, and four pregnancies resulted in early spontaneous abortions. Although short-term renal outcome was good in most women, long-term renal outcome was poor; among the 14 women, four had CKD stage 1-4, five had received a renal allograft, and three were dialysis-dependent at study end. We prospectively followed nine pregnancies of four women and treated six of these pregnancies with prophylactic plasma infusions (one pregnancy resulted in p-aHUS, one intrauterine fetal death occurred, and seven pregancies were uneventful). Our study emphasizes the frequency of successful pregnancies in women with aHUS. Close monitoring of such pregnancies for episodes of thrombotic microangiopathy is essential but, the best strategy to prevent these episodes remains unclear.

Non-syndromic odontogenic keratocysts: A rare case report

PubMed Central

Kurdekar, Raghavendra S.; Prakash, Jeevan; Rana, A. S.; Kalra, Puneet

2013-01-01

Odontogenic keratocysts are very well documented in the literature. Multiple odontogenic keratocysts (OKCs) are one of the most frequent features of nevoid basal cell carcinoma syndrome (NBCCS). It is linked with mutation in the PTCH gene (human homolog of the drosophila segment polarity gene, “patched”,). Partial expression of the gene may result in occurrence of only multiple recurring OKC without any associated systemic findings. A rare case of multiple odontogenic keratocysts unassociated with any syndrome is reported, so as to add to the growing number of such cases in the literature. The possibility of this case being a partial expression of the Gorlin-Goltz syndrome is discussed. PMID:24163561

PATHOPHYSIOLOGY, DIAGNOSIS AND TREATMENTOF DUMPING SYNDROME AND ITS RELATION TO BARIATRIC SURGERY

CHAVES, Yasmin da Silva; DESTEFANI, Afrânio Côgo

2016-01-01

ABSTRACT Introduction The dumping syndrome is frequent in bariatric surgery. It is probably the most common syndrome following partial or complete gastrectomy. Its prevalence in partial gastrectomy can reach up to 50%, thus it can be a significant complication arising from some types of bariatric surgeries. Objective: Critical analysis on dumping syndrome, its pathophysiology, diagnosis and treatment. Methods: A literature review was performed using the key words: 'dumping syndrome', 'bariatric surgery' and 'rapid dumping syndrome'. Inclusion criteria were: books, original works, case reports and meta-analyzes, and the exclusion criterion was literature review. Concerning the publication time, articles were screened between 1960 and May 2015. Results: The dumping syndrome is complication arising from obesity surgeries, but also can be a result of vagus nerve damage. Diagnosis is done primarily through the use of questionnaires based on scores. Conclusion: The Sigstad score and Arts survey are valid means for assessing the dumping syndrome. Initial therapy consists in the adoption of dietary measures, short acting drugs administration. PMID:27683791

Baraitser and Winter syndrome with growth hormone deficiency.

PubMed

Chentli, Farida; Zellagui, Hadjer

2014-01-01

Baraitser-Winter syndrome (BWS), first reported in 1988, is apparently due to genetic abnormalities that are still not well-defined, although many gene abnormalities are already discovered and de novo missense changes in the cytoplasmic actin-encoding genes (called ACTB and ACTG1) have been recently discovered. The syndrome combines facial and cerebral malformations. Facial malformations totally or partially present in the same patient are: Iris coloboma, bilateral ptosis, hypertelorism, broad nasal bridge, and prominent epicanthic folds. The various brain malformations are probably responsible for growth and mental retardation. To the best of our knowledge, the syndrome is very rare as few cases have been reported so far. Our aim was to describe a child with a phenotype that looks like BWS with proved partial growth hormone (GH) deficiency which was not reported before. A girl aged 7-year-old of consanguineous parents was referred for short stature and mental retardation. Clinical examination showed dwarfism and a delay in her mental development. Other clinical features included: Strabismus, epicanthic folds, broad nasal bridge, and brain anomalies such as lissencephaly, bilateral hygroma, and cerebral atrophy. Hormonal assessment showed partial GH deficiency without other endocrine disorders. Our case looks exactly like BWS. However, apart from facial and cerebral abnormalities, there is a partial GH deficiency which can explain the harmonious short stature. This case seems worth to be reported as it adds GH deficiency to the very rare syndrome.

Congenital anomalies may be associated with Wilms tumor either as isolated anomalies or as part of a congenital malformation syndrome. Nephroblastoma occurring in association with polycystic kidneys is very rare. The optimal surgical management of nephroblastoma in the setting of polycystic kidneys is not defined because of the rarity of this presentation. PHACE syndrome includes posterior fossa anomalies, hemangioma, arterial lesions, cardiac abnormalities/coarctation of aorta, and eye abnormalities. We report a 17-month-old baby with bilateral polycystic kidneys and PHACE syndrome who developed nephroblastoma in the right polycystic kidney which was treated successfully with nephron-sparing partial nephrectomy and chemotherapy.

Ulnar hammer syndrome is an uncommon form of arterial insufficiency. Many treatments have been described, and debate continues about the best option. The goal of this systematic review was to determine whether ulnar hammer syndrome has an occupational association, to identify the most reliable diagnostic test, and to determine the best treatment modality. A comprehensive literature search was conducted using the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, and EMBASE. Data from articles meeting inclusion criteria were collected in duplicate. Methodological quality of studies was assessed using the Methodological Index for Nonrandomized Studies scale. Thirty studies were included in the systematic review. No randomized controlled trials were identified. There is low-quality evidence suggestive of an association between exposure to repetitive hand trauma and vibration and ulnar hammer syndrome. Various diagnostic investigations were used, but few were compared, making it difficult to determine the most reliable diagnostic test. Numerous nonoperative and operative treatments were reported. With nonoperative treatment, 12 percent had complete resolution and 70 percent had partial resolution of their symptoms. Of patients treated operatively, 42.5 percent had complete resolution and 42.5 percent had partial resolution of their symptoms. The heterogeneity in study design and outcome measures limits definitive conclusions about occupational association, best diagnostic test, and treatment for ulnar hammer syndrome. However, there is low-quality evidence that suggests that most patients with ulnar hammer syndrome will have partial relief of symptoms with nonoperative treatment, and operative treatment results in complete or partial resolution of symptoms in the majority of cases.

To determine the etiology, clinical features and outcome of fulminant hepatic failure in pregnancy. An observational hospital based study was conducted at Isra University hospital Hyderabad from 1st March 2009 to 28th February 2010. Total 1192 obstetric patients were admitted in obstetrics & gynaecology department during this period, of whom 52 were with Fulminant hepatic failure in pregnancy and were included in this study. A pre-designed structured proforma was used. All patients had clinical history and underwent a physical examination. Routine laboratory tests, liver function tests and viral serology were performed in all cases. All results were analyzed on statistical software SPSS version 11. Frequencies and percentages were calculated, the final outcome was recorded. Out of 52, 6 (11.5%) presented in the first trimester, 4 (7.6%) in the second trimester and 42 (80.7%) were in their 3rd trimester of pregnancy. Etiology of the disease was Hepatitis E in 28 (53.8%), Hepatitis B in 9 (17.3%), Hepatitis C in 7 (13.5%) HELLP syndrome in 7 (13.5%) and acute fatty liver of pregnancy in 1 (3.57%) case. Maternal mortality was 15 (28.8%) and foetal mortality was 40 (77%). Only 12 (23.1%) new born remained alive. Fulminant hepatic failure in pregnancy has very high foetal and maternal mortality which is mostly due to viral hepatitis E.

Trisomy 22 with 'cat eye' anomaly.

The case of a 10-month-old girl with an extra G-like chromosome is presented. Quinacrine, trypsin-Giemsa, and reverse banding identified the extra chromosome as no. 22. The phenotype of the patient is unique in that unilateral iris coloboma was observed, unlike the 18 cases of full trisomy 22 already published. This represents the first reported case of full trisomy 22 with this coloboma, or 'cat eye' anomaly, which is usually associated with partial trisomy 22. It is suggested that the use of the term 'cat eye syndrome' be revised. The terms 'partial trisomy 22 syndrome' and 'trisomy 22 syndrome' should be used instead. Images PMID:336892

Severe psychomotor delay in a severe presentation of cat-eye syndrome.

Cat-eye syndrome is a rare genetic syndrome of chromosomal origin. Individuals with cat-eye syndrome are characterized by the presence of preauricular pits and/or tags, anal atresia, and iris coloboma. Many reported cases also presented with variable congenital anomalies and intellectual disability. Most patients diagnosed with CES carry a small supernumerary bisatellited marker chromosome, resulting in partial tetrasomy of 22p-22q11.21. There are two types of small supernumerary marker chromosome, depending on the breakpoint site. In a very small proportion of cases, other cytogenetic anomalies are reportedly associated with the cat-eye syndrome phenotype. Here, we report a patient with cat-eye syndrome caused by a type 1 small supernumerary marker chromosome. The phenotype was atypical and included a severe developmental delay. The use of array comparative genomic hybridization ruled out the involvement of another chromosomal imbalance in the neurological phenotype. In the literature, only a few patients with cat-eye syndrome present with a severe developmental delay, and all of the latter carried an atypical partial trisomy 22 or an uncharacterized small supernumerary marker chromosome. Hence, this is the first report of a severe neurological phenotype in cat-eye syndrome with a typical type 1 small supernumerary marker chromosome. Our observation clearly complicates prognostic assessment, particularly when cat-eye syndrome is diagnosed prenatally.

Severe preeclampsia is a disorder of pregnancy characterized by high blood pressure and significant proteinuria after 20 weeks gestation. Severe preeclampsia and eclampsia have considerable adverse impacts on maternal, fetal, and neonatal health especially in low-resource countries. Hypertensive disorders of pregnancy are the third leading cause of maternal deaths in Sub-Saharan Africa. Significant avoidable maternal and neonatal morbidity and mortality may result. This study aimed 1) to determine the incidence of severe preeclampsia/eclampsia in a low-resource setting; 2) to determine the maternal complications of severe preeclampsia/eclampsia in a low-resource setting; 3) to determine the perinatal outcomes of severe preeclampsia/eclampsia in a low-resource setting. This was a retrospective descriptive cohort study carried out at Mpilo Central Hospital, a tertiary teaching referral government hospital in a low-resource setting in Bulawayo, Zimbabwe. Data were obtained from the birth registers in labor ward, intensive care unit, and neonatal intensive care unit of patients who had a diagnosis of severe preeclampsia or eclampsia for the period January 1, 2016, to December 31, 2016. The case notes were retrieved and the demographic, clinical, and outcome data were gathered. There were 9,086 deliveries at the institution during the period January 1, 2016, to December 31, 2016. There were 121 cases of severe preeclampsia/eclampsia. The incidence of severe preeclampsia/eclampsia was 1.3% at Mpilo Central Hospital. The most common major complication was HELLP syndrome (9.1%). Maternal mortality was 1.7%. There were 127 babies born with six sets of twins, 49.6% of the babies were lost through stillbirths and early neonatal deaths. The incidence of severe preeclampsia/eclampsia at Mpilo Central Hospital was 1.3%. The most common maternal complication was hemolysis elevated liver enzymes low platelet syndrome. Maternal mortality was 1.7% due to acute renal failure. Nearly half (49.6%) of the babies born were lost to stillbirths and early neonatal deaths.

Small supernumerary marker chromosomes are present in about 0.05% of the human population. In approximately 28% of persons with these markers (excluding the approximately 60% derived from one of the acrocentric chromosomes), an abnormal phenotype is observed. We report on a 3-month-old girl with intrauterine growth retardation, craniofacial features, hypotonia, partial coloboma of iris and total anomalous pulmonary venous return. Cytogenetic analysis showed the presence of a supernumerary marker chromosome, identified by fluorescence in situ hybridization as part of chromosome 22, and conferring a proximal partial trisomy 22q22.21, not encompassing the DiGeorge critical region (RP11-154H4 + , TBX1-). This observation adds new information relevant to cat eye syndrome and partial trisomy of 22q. 2008 Wiley-Liss, Inc.

Albinism is an inherited abnormality of melanin synthesis with incidence of one per 20,000 births. Its clinical manifestations are related to the reduction or absence of pigmentation in the visual system and/or the skin and teguments. The clinical spectrum of Oculocutaneous Albinism (OCA) has four types ranging from OCA 1 - 4, of which OCA 1, A-1 is the most severe form. Partial cutaneous albinism which is a subtype of OCA is associated with systemic immunodeficiency disorders like Chediak Higashi (CHS), Griscelli (GS) and Hermansky-Pudlak (HPS) syndromes. A7 years boy was labeled initially as a case of Hermansky Pudlak syndrome at the age of 01 year. He as well as his 4 years old younger brother when examined in detail along with audiological investigations were diagnosed as a rare presentation of both Hermansky Pudlak and Waardenburg's syndrome.

Rufinamide is a new antiepileptic drug recently approved as adjunctive treatment for generalized seizures in Lennox-Gastaut syndrome. We undertook a retrospective analysis of 77 patients with refractory epilepsy and receiving rufinamide to evaluate the drug's efficacy, tolerability, safety, and dosing schedules. It appeared efficacious in diverse epilepsy syndromes, with the highest responder rate in focal cryptogenic epilepsies (81.1% of patients with >50% response rate), and in diverse seizure types, with the highest responder rate in tonic/atonic and partial seizures (48.6% and 46.7% of patients with >50% response rate, respectively). Rufinamide was well tolerated: only 13% of patients developed side effects necessitating drug withdrawal. These findings suggest that rufinamide may possess good efficacy and tolerability, and that its efficacy may extend to epilepsy syndromes beyond Lennox-Gastaut, including both partial and generalized epilepsy syndromes.

Leigh syndrome is a mitochondrial encephalomyopathy that occurs due to "cytochrome c oxidase deficiency". Few psychiatric disorders have been defined that are associated with Leigh syndrome. The objective of this work is to study relations between mitochondrial dysfunction and psychiatric disorders. It was a 20 year old male patient, who received Modopar, for severe extra pyramidal symptoms caused by Leigh syndrome. He developed, four months ago, acute psychotic symptoms such as audio-visual hallucinations, persecution and mystic delirium. The cerebral MRI has shown signal abnormalities in central grey nucleus. The EEG recording and blood test were normal. The hypothesis of drug induced psychiatric disorders (Modopar) was possible. The evolution under atypical antipsychotic was only partial. In this case, the cerebrospinal fluid and lactate levels mean that mitochondria were not an overall explanation for these psychiatric disorders but may at least play a partial role. Psychiatric disorders may just be acomorbidity.

2010-01-01

Diabetes insipidus is a rare disorder in pregnant women, predating pregnancy or appearing for the first time during gestation. In pregnancy it usually affects women with HELLP syndrome or acute fatty liver of pregnancy and results from the reduced hepatic degradation of placental vasopressinase leading to its increased activity. Although infiltrative diseases have been found to cause diabetes insipidus in non-pregnant population, very few studies showed that these disorders may manifest for the first time during gestation. We describe here the case of transient diabetes insipidus in two subsequent pregnancies of a female with hemochromatosis. The first symptoms of this disease appeared for the first time at the beginning of the third trimester of her second pregnancy, and diagnosis was established on the basis of typical clinical presentation, confirmed by a water deprivation test. Diabetes insipidus resulted from the increased activity of vasopressinase, caused by hemochromatosis-induced liver dysfunction, the presence of which was confirmed between the pregnancies by liver biopsy and identification of the HFE gene mutation. Subsequent desferrioxamine treatment resulted in a less severe clinical course of diabetes insipidus in the last patient's pregnancy. In both pregnancies, the patient was successfully treated with oral desmopressin, which is resistant to degradation by placental vasopressinase. Although unrecognized pituitary disorders may pose a serious health problem to the mother and fetus, hemochromatosis-induced diabetes insipidus, as the case of our patient demonstrates, if effectively diagnosed and treated, cannot be regarded as a contraindication for pregnancy.

Effects of Parity on Blood Pressure among African-American Women

It has been well established that age, ethnicity, weight, and lifestyle behaviors can affect blood pressure (BP). Co-morbid conditions such as HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets), pre-eclampsia, and previous hypertension diagnosis might also be risks for chronic hypertension among women who have had children. Although parity has been linked to changes in blood pressure in White women, these findings have not been replicated among African-American women. The purpose of this study was to determine if the number of pregnancies urban African-American women have effects BMI and blood pressure readings later in life. Results indicated that women with a previous diagnosis of hypertension had higher SBP and DBP, and a slightly higher BMI than women who had never been diagnosed. Additionally, women with a prior history of hypertension had more children than those without a diagnosis of hypertension. As parity increased, SBP increased. However, DBP decreased after 3 to 4 children, even with increases in BMI. This study shows that parity may increase African-American women’s risk for hypertension in terms of increased SBP and BMI with increased parity. However, increased parity and BMI may also serve as protective factors in lowering DBP. Further studies, with larger samples followed throughout their pregnancies, is needed before more definitive statements may be drawn about the effects of parity on BMI and blood pressure readings among African-American women can be made.

The lost children.

Smith, S

1999-03-01

Women who have lost children to perinatal complications, are subjected to pain and grief continuously; however their agony increases on remembrance days such as birthdate, or on Mother's Day. Fathers, siblings and grandparents suffer too. Common disorders of pregnancy, such as pregnancy-induced hypertension (PIH), or the more serious pre-eclampsia, HELLP syndrome, or eclampsia, can lead to devastating effects such as miscarriage, stillbirth, or neonatal death; or at the very least, a sick infant. With many of these consequences, the loss of the dreams, hopes and plans that parents have made is imminent. The investigation of the psychosocial aspects of 'high-risk' pregnancy has never been fully addressed. However, the threat of loss, or the actual experience, may provoke the onset of a potential psychological crisis during the perinatal period. Therefore, it is important that these issues be addressed by the nurse in order to aid the development of coping mechanisms to enable women and their families to deal with what may happen. This may be done by predicting the stages of the bereavement process experienced by these women and their family members, as outlined in the Kubler-Ross model of bereavement (1969), which is indicative of many types of grief reactions. Other issues including the restriction in activity, uncertainty of pregnancy outcomes, disruption in work or career activities, financial strains, and reduced labour and birthing options, become concerns for high-risk pregnant women. The way women deal with these issues and the pathways nurses can take to help these women develop effective coping strategies, will be addressed also.

Peptide Receptor Radionuclide Therapy with 177Lu-DOTATATE for Metastatic Neuroendocrine Tumor Occurring in Association with Multiple Endocrine Neoplasia Type 1 and Cushing's Syndrome.

Neuroendocrine tumor (NET) occurring in association with other endocrine syndromes forms a distinct entity. The aim was to assess the therapy response profile of the routine peptide receptor radionuclide therapy (PRRT) in this relatively uncommon but clinically challenging subgroup of patients. A retrospective analysis was undertaken from the case records from those who were treated with 177 Lu-DOTATATE for metastatic NET. In addition to assessing the therapeutic efficacy, emphasis was also given to study lesional sites and scan pattern. A total of 5 cases were found: In this series of five cases, four belonged to multiple endocrine neoplasia type 1 (MEN1) syndrome; in these four MEN1 syndrome patients, the primary site of NET was thymic region ( n = 1), duodenum ( n = 1), and pancreas ( n = 2). The fifth case was of Cushing's syndrome with the primary site of NET in the thymus. A good symptomatic response was observed in all MEN1 syndrome cases (100%) and progression of symptoms in the patient with Cushing's syndrome. The biochemical response (assessed by measurement of tumor marker serum chromogranin A) demonstrated very good partial response (defined by more than 75% reduction of tumor marker) in 2 MEN1 cases and Cushing's syndrome, good partial response (25-75% reduction of tumor marker) in the remaining 2 MEN1 cases. Scan wise (assessed by technetium [ 99m Tc]-hydrazinonicotinamide [HYNIC]-tektrotyd [TOC]/ 68 Ga-DOTA-NOC/TATE positron emission tomography-computed tomography [PET-CT] and fluorodeoxyglucose [FDG] PET-CT) partial response was observed in 3 MEN1 cases, stable disease was noted in one MEN1 case and disease progression was noted in the patient with Cushing's syndrome. The change in FDG uptake was found to be an important sensitive scan parameter in the treatment evaluation of NETs compared to somatostatin receptor-based imaging in the cases with low MiB1 index. In our series, good palliative response to 177 Lu-DOTA-octreotate (DOTATATE) PRRT was observed in most NET patients associated with MEN1 syndrome without any major hematological or renal toxicity.

Possible induction of West syndrome by oxcarbazepine therapy in a patient with complex partial seizures.

Veerapandiyan, Aravindhan; Singh, Piyush; Mikati, Mohamad A

2012-03-01

Oxcarbazepine has been reported to precipitate myoclonic, generalised tonic-clonic, absence, and complex partial seizures, and carbamazepine to precipitate absences, myoclonic seizures and spasms. Here, we report a one-year, six-month-old girl with complex partial seizures who developed infantile spasms, developmental regression, and hypsarrhythmia during the two weeks directly following initiation of oxcarbazepine (14 mg/kg/day). All of these resolved within a few days after discontinuation of this medication. Although we cannot rule out that the above association may have been coincidental, or that the improvement may have been due to concurrent therapy, this case raises the possibility that oxcarbazepine, like carbamazepine, may precipitate infantile spasms and West syndrome.

High fractions of inspired oxygen may augment lung damage to exacerbate lung injury in patients with acute respiratory distress syndrome. Participants enrolled in Acute Respiratory Distress Syndrome Network trials had a goal partial pressure of oxygen in arterial blood range of 55-80 mm Hg, yet the effect of oxygen exposure above this arterial oxygen tension range on clinical outcomes is unknown. We sought to determine if oxygen exposure that resulted in a partial pressure of oxygen in arterial blood above goal (> 80 mm Hg) was associated with worse outcomes in patients with acute respiratory distress syndrome. Longitudinal analysis of data collected in these trials. Ten clinical trials conducted at Acute Respiratory Distress Syndrome Network hospitals between 1996 and 2013. Critically ill patients with acute respiratory distress syndrome. None. We defined above goal oxygen exposure as the difference between the fraction of inspired oxygen and 0.5 whenever the fraction of inspired oxygen was above 0.5 and when the partial pressure of oxygen in arterial blood was above 80 mm Hg. We then summed above goal oxygen exposures in the first five days to calculate a cumulative above goal oxygen exposure. We determined the effect of a cumulative 5-day above goal oxygen exposure on mortality prior to discharge home at 90 days. Among 2,994 participants (mean age, 51.3 yr; 54% male) with a study-entry partial pressure of oxygen in arterial blood/fraction of inspired oxygen that met acute respiratory distress syndrome criteria, average cumulative above goal oxygen exposure was 0.24 fraction of inspired oxygen-days (interquartile range, 0-0.38). Participants with above goal oxygen exposure were more likely to die (adjusted interquartile range odds ratio, 1.20; 95% CI, 1.11-1.31) and have lower ventilator-free days (adjusted interquartile range mean difference of -0.83; 95% CI, -1.18 to -0.48) and lower hospital-free days (adjusted interquartile range mean difference of -1.38; 95% CI, -2.09 to -0.68). We observed a dose-response relationship between the cumulative above goal oxygen exposure and worsened clinical outcomes for participants with mild, moderate, or severe acute respiratory distress syndrome, suggesting that the observed relationship is not primarily influenced by severity of illness. Oxygen exposure resulting in arterial oxygen tensions above the protocol goal occurred frequently and was associated with worse clinical outcomes at all levels of acute respiratory distress syndrome severity.

Screwless fixed detachable partial overdenture treatment for atrophic partial edentulism of the anterior maxilla.

PubMed

Flanagan, Dennis

2008-01-01

This is a case report of the restoration of a partially edentulous atrophic anterior maxilla and atrophic mandibular posterior ridges. This case report demonstrates one method for successful treatment of partial edentulism at No. 7 to 10, where interlock attachments on natural cuspids and mini dental implants support an acrylic-based screwless fixed detachable partial denture to provide lip support and masticatory function in the anterior maxilla. The presenting qualities of this case were similar to combination syndrome.

Review of somatic symptoms in post-traumatic stress disorder.

PubMed

Gupta, Madhulika A

2013-02-01

Post-traumatic stress disorder (PTSD) is associated with both (1) 'ill-defined' or 'medically unexplained' somatic syndromes, e.g. unexplained dizziness, tinnitus and blurry vision, and syndromes that can be classified as somatoform disorders (DSM-IV-TR); and (2) a range of medical conditions, with a preponderance of cardiovascular, respiratory, musculoskeletal, neurological, and gastrointestinal disorders, diabetes, chronic pain, sleep disorders and other immune-mediated disorders in various studies. Frequently reported medical co-morbidities with PTSD across various studies include cardiovascular disease, especially hypertension, and immune-mediated disorders. PTSD is associated with limbic instability and alterations in both the hypothalamic- pituitary-adrenal and sympatho-adrenal medullary axes, which affect neuroendocrine and immune functions, have central nervous system effects resulting in pseudo-neurological symptoms and disorders of sleep-wake regulation, and result in autonomic nervous system dysregulation. Hypervigilance, a central feature of PTSD, can lead to 'local sleep' or regional arousal states, when the patient is partially asleep and partially awake, and manifests as complex motor and/or verbal behaviours in a partially conscious state. The few studies of the effects of standard PTSD treatments (medications, CBT) on PTSD-associated somatic syndromes report a reduction in the severity of ill-defined and autonomically mediated somatic symptoms, self-reported physical health problems, and some chronic pain syndromes.

The short arm deletion syndrome of chromosome 4 (4p- syndrome).

Zellweger, H; Bardach, J; Bordwell, J; Williams, K

1975-01-01

Partial deletion of the short arm of chromosome 4 (4p-) represents another (rare) cause of cleft lip and cleft palate. Further characteristic manifestations of the syndrome (also called Wolf or Wolf-Hirschhorn syndrome) are growth failure, microcephaly, prominent glabella, hypertelorism, beaked nose, poorly differentiated and low set ears, cardiac and renal malformation and hypospadias. Life expectancy is often shortened. The 4p- syndrome has many features in common with another deletion syndrome, the cri-du-chat syndrome, and also with the Smith-Lemli-Opitz syndrome. The latter is a hereditary condition with normal karyotype. The cri-du-chat syndrome is characterized by a peculiar high-pitched, mewing cry and can be differentiated from the Wolf syndrome by the different staining characteristics (banding) of chromosomes 4 and 5.

Human lipodystrophies: genetic and acquired diseases of adipose tissue

Human lipodystrophies represent a heterogeneous group of diseases characterized by generalized or partial fat loss, with fat hypertrophy in other depots when partial. Insulin resistance, dyslipidemia and diabetes are generally associated, leading to early complications. Genetic forms are uncommon: recessive generalized congenital lipodystrophies result in most cases from mutations in the genes encoding seipin or the 1-acyl-glycerol-3-phosphate-acyltransferase 2 (AGPAT2). Dominant partial familial lipodystrophies result from mutations in genes encoding the nuclear protein lamin A/C or the adipose transcription factor PPARγ. Importantly, lamin A/C mutations are also responsible for metabolic laminopathies, resembling the metabolic syndrome and progeria, a syndrome of premature aging. A number of lipodystrophic patients remain undiagnosed at the genetic level. Acquired lipodystrophy can be generalized, resembling congenital forms, or partial, as the Barraquer-Simons syndrome, with loss of fat in the upper part of the body contrasting with accumulation in the lower part. Although their aetiology is generally unknown, they could be associated with signs of auto-immunity. The most common forms of lipodystrophies are iatrogenic. In human immunodeficiency virus-infected patients, some first generation antiretroviral drugs were strongly related with peripheral lipoatrophy and metabolic alterations. Partial lipodystrophy also characterize patients with endogenous or exogenous long-term corticoid excess. Treatment of fat redistribution can sometimes benefit from plastic surgery. Lipid and glucose alterations are difficult to control leading to early occurrence of diabetic, cardio-vascular and hepatic complications. PMID:20551664

1997-01-01

We report two siblings--a 5 1/2 year old female and her 4 1/2 year old brother, both presenting the classical clinical findings of oculo-dento-digital dysplasia (ODD). 1. Digital anomalies: bilateral complete cutaneous syndactyly of fingers IV-V (III-IV-V at the left hand of the boy) and camptodactyly IV. 2. Facial and ocular anomalies: microphtalamos-epicanthal folds, small midfacies, thin nose with hypoplastic alae nasi and small nares. 3. Dental anomalies with partial dental agenesis and enamel hypoplasia. Examination of the parents showed a bilateral cutaneous syndactyly IV-V in the father as the sole partial manifestation of ODD. The findings in the present family confirm the autosomal dominant inheritance of ODD with great variability in clinical expression. Moreover, the facial morphology (thin, hypoplastic nose) observed in several ODD patients suggests nosological overlap with the Hallerman-Streiff syndrome and could indicate that both syndromes are variable expressions of a contiguous gene deletion syndrome.

The aim of this study is to describe the prevalence, anatomy, associations and clinical impact of partial anomalous pulmonary venous return in patients with Turner syndrome. All Turner patients who presented at our Turner clinic, between January 2007 and October 2015 were included in this study and underwent ECG, echocardiography and advanced imaging such as cardiac magnetic resonance or computed tomography as part of their regular clinical workup. All imaging was re-evaluated and detailed anatomy was described. Partial anomalous pulmonary venous return was diagnosed in 24 (25%) out of 96 Turner patients included and 14 (58%) of these 24 partial anomalous pulmonary venous return had not been reported previously. Right atrial or ventricular dilatation was present in 11 (46%) of 24 partial anomalous pulmonary venous return patients. When studied with advanced imaging modalities and looked for with specific attention, PAPVR is found in 1 out of 4 Turner patients. Half of these patients had right atrial and/or ventricular dilatation. Evaluation of pulmonary venous return should be included in the standard protocol in all Turner patients. Copyright © 2017.

Concurrent Van der Woude syndrome and Turner syndrome: A case report.

PubMed

Los, Evan; Baines, Hayley; Guttmann-Bauman, Ines

2017-01-01

Most cases of Van der Woude syndrome are caused by a mutation to interferon regulatory factor 6 on chromosome 1. Turner syndrome is caused by complete or partial absence of the second sex chromosome in girls. We describe a unique case of the two syndromes occurring concurrently though apparently independently in a girl with Van der Woude syndrome diagnosed at birth and Turner syndrome at 14 years 9 months. Short stature was initially misattributed to Van der Woude syndrome and pituitary insufficiency associated with clefts before correctly diagnosing Turner syndrome. We discuss the prevalence of delayed diagnosis of Turner syndrome, the rarity of reports of concurrent autosomal chromosome mutation and sex chromosome deletion, as well as the need to consider the diagnosis of Turner syndrome in all girls with short stature regardless of prior medical history.

Anaesthesia Management in a Patient with Waardenburg Syndrome and Review of the Literature.

Peker, Kevser; Ergil, Julide; Öztürk, İbrahim

2015-10-01

Waardenburg syndrome is a rare autosomal dominant disease that may cause hearing loss, pigmentary abnormalities, neurocristopathy and partial albinism. Incidence is estimated as 2%-3% among the cases of congenital deafness and 1/42,000 of the general population. Children with Waardenburg syndrome usually require anaesthesia for the cochlear implant operation in early age. The features of the syndrome that may bear importance for anaesthetic management are laryngomalacia, multiple muscle contractures, limited neck movements, cyanotic cardiopathy and electrolyte imbalance. Patients with Waardenburg syndrome stand for difficult airway. We aimed to report anaesthetic management of a child with Waardenburg syndrome who underwent surgery for cochlear implantation.

l-leucine partially rescues translational and developmental defects associated with zebrafish models of Cornelia de Lange syndrome

2015-01-01

Cohesinopathies are human genetic disorders that include Cornelia de Lange syndrome (CdLS) and Roberts syndrome (RBS) and are characterized by defects in limb and craniofacial development as well as mental retardation. The developmental phenotypes of CdLS and other cohesinopathies suggest that mutations in the structure and regulation of the cohesin complex during embryogenesis interfere with gene regulation. In a previous project, we showed that RBS was associated with highly fragmented nucleoli and defects in both ribosome biogenesis and protein translation. l-leucine stimulation of the mTOR pathway partially rescued translation in human RBS cells and development in zebrafish models of RBS. In this study, we investigate protein translation in zebrafish models of CdLS. Our results show that phosphorylation of RPS6 as well as 4E-binding protein 1 (4EBP1) was reduced in nipbla/b, rad21 and smc3-morphant embryos, a pattern indicating reduced translation. Moreover, protein biosynthesis and rRNA production were decreased in the cohesin morphant embryo cells. l-leucine partly rescued protein synthesis and rRNA production in the cohesin morphants and partially restored phosphorylation of RPS6 and 4EBP1. Concomitantly, l-leucine treatment partially improved cohesinopathy embryo development including the formation of craniofacial cartilage. Interestingly, we observed that alpha-ketoisocaproate (α-KIC), which is a keto derivative of leucine, also partially rescued the development of rad21 and nipbla/b morphants by boosting mTOR-dependent translation. In summary, our results suggest that cohesinopathies are caused in part by defective protein synthesis, and stimulation of the mTOR pathway through l-leucine or its metabolite α-KIC can partially rescue development in zebrafish models for CdLS.

2002-05-01

Heterotaxy syndrome is a rare clinical entity in adults, characterized by situs ambiguus, congenital heart defects, and splenic malformations. We report the case of an adult with heterotaxy syndrome (including situs ambiguus, bilateral superior vena cava, hypoplastic right-sided spleen and portosystemic shunts) presenting with dyspnea due to severe pulmonary hypertension. Vasodilatory therapy was initiated, leading to marked reduction of clinical symptoms. This case exhibits 2 particular and partially novel features: primary diagnosis of heterotaxy syndrome may be delayed until adulthood, and heterotaxy syndrome may be associated with pulmonary hypertension, possibly on the basis of longstanding portosystemic shunts.

The Mayer-Rokitansky-Küster-Hauser syndrome is defined as congenital aplasia of müllerian ducts derived structures in females with a normal female chromosomal and gonadal sex. Most cases with Mayer-Rokitansky-Küster-Hauser syndrome are sporadic, although familial cases have been reported. The genetic basis of Mayer-Rokitansky-Küster-Hauser syndrome is largely unknown and seems heterogeneous, and a small number of cases were found to have mutations in the WNT4 gene. The aim of this study was to identify possible recurrent submicroscopic imbalances in a cohort of familial and sporadic cases with Mayer-Rokitansky-Küster-Hauser syndrome. Multiplex ligation-dependent probe amplification was used to screen the subtelomeric sequences of all chromosomes in 30 patients with Mayer-Rokitansky-Küster-Hauser syndrome (sporadic, n = 27 and familial, n = 3). Segregation analysis and pyrosequencing were applied to validate the MLPA results in the informative family. Partial duplication of the Xpter pseudoautosomal region 1 containing the short stature homeobox (SHOX) gene was detected in five patients with Mayer-Rokitansky-Küster-Hauser syndrome (familial, n = 3 and sporadic, n = 2) and not in 53 healthy controls. The duplications were not overlapping, and SHOX was never entirely duplicated. Haplotyping in the informative family revealed that SHOX gene duplication was inherited from the unaffected father and was absent in two healthy sisters. Partial duplication of SHOX gene is found in some cases with both familial and sporadic Mayer-Rokitansky-Küster-Hauser type I syndrome.

Dent disease is an X-linked recessive disorder affecting the proximal tubule and is characterized by low-molecular-weight proteinuria (LMWP), hypercalciuria, nephrocalcinosis/nephrolithiasis with a variable number of features of Fanconi syndrome. It is most often associated with mutations in CLCN5, which encodes the endosomal electrogenic chloride/proton exchanger ClC-5. Renal acidification abnormalities are only rarely seen in Dent disease, whereas the hypokalemic metabolic alkalosis associated with hyperreninemic hyperaldosteronism (Bartter-like syndrome) has been reported in only one patient so far. We report on a 5-year-old boy with Dent disease caused by mutation in CLCN5 gene, c.1073G>A, who presented with hypokalemic metabolic alkalosis and hyperreninemic hyperaldosteronism persisting over the entire follow-up. No mutations were found in NKCC2, ROMK, NCCT, or ClC-Kb genes. In addition, the patient exhibited growth failure associated with partial growth hormone (GH) deficiency. Coexistence of Bartter-like syndrome features with LMWP should prompt a clinician to search for Dent disease. The Bartter syndrome phenotype seen in Dent disease patients may represent a distinct form of Bartter syndrome, the exact mechanism of which has yet to be fully elucidated. Growth delay that persists in spite of appropriate therapy should raise suspicion of other causes, such as GH deficiency.

Partial Tetrasomy of Chromosome 22q11.1 Resulting from a Supernumerary Isodicentric Marker Chromosome in a Boy with Cat-eye Syndrome

The 22q11 region has been implicated in chromosomal rearrangements that result in altered gene dosage, leading to three different congenital malformation syndromes: DiGeorge syndrome, cat-eye syndrome (CES), and der(22) syndrome. Although DiGeorge syndrome is a common genomic disorder on 22q11, CES is quite rare, and there has been no report of Korean CES cases with molecular cytogenetic confirmation. In this study, we present the phenotypic and genetic characteristics of a 3-month-old boy with CES. Clinical findings included micropthalmia, multiple colobomata, and renal and genital anomalies. Cytogenetic analyses showed the presence of a supernumerary marker chromosome, which was identified as a bisatellited and isodicentric chromosome derived from an acrocentric chromosome. The results of array comparative genomic hybridization and fluorescence in situ hybridization studies confirmed the karyotype as 47,XY,+mar.ish idic(22)(q11.1) (D22S43+).arr 22q11.1(15,500,000-15,900,000)x4, resulting in a partial tetrasomy of 22q11.1.

: Charles Bonnet Syndrome is a condition where visual hallucinations occur as a result of damage along the visual pathway. Patients with Charles Bonnet Syndrome maintain partial or full insight that the hallucinations are not real, absence of psychological conditions, and absence of hallucinations affecting other sensory modalities, while maintaining intact intellectual functioning. Charles Bonnet Syndrome has been well documented in neurologic, geriatric medicine, and psychiatric literature, but there is lack of information in optometric and ophthalmologic literature. Therefore, increased awareness of signs and symptoms associated with Charles Bonnet Syndrome is required among practicing clinicians. This review of the literature will also identify other etiologies of visual hallucinations, pathophysiology of Charles Bonnet Syndrome, and effective management strategies.

Down syndrome (DS) is one of the most frequent congenital birth defects, and the most common genetic cause of mental retardation. In most cases, DS results from the presence of an extra copy of chromosome 21. DS has a complex phenotype, and a major goal of DS research is to identify genotype–phenotype correlations. Cases of partial trisomy 21 and other HSA21 rearrangements associated with DS features could identify genomic regions associated with specific phenotypes. We have developed a BAC array spanning HSA21q and used array comparative genome hybridization (aCGH) to enable high-resolution mapping of pathogenic partial aneuploidies and unbalanced translocations involving HSA21. We report the identification and mapping of 30 pathogenic chromosomal aberrations of HSA21 consisting of 19 partial trisomies and 11 partial monosomies for different segments of HSA21. The breakpoints have been mapped to within ∼85 kb. The majority of the breakpoints (26 of 30) for the partial aneuploidies map within a 10-Mb region. Our data argue against a single DS critical region. We identify susceptibility regions for 25 phenotypes for DS and 27 regions for monosomy 21. However, most of these regions are still broad, and more cases are needed to narrow down the phenotypic maps to a reasonable number of candidate genomic elements per phenotype. PMID:19002211

Although congenital abnormalities in the male reproductive tract are common, their causes remain poorly understood. We studied associations between hypertensive disorders of pregnancy (pre-gestational hypertension, gestational hypertension, and preeclampsia) and the genital anomalies, cryptorchidism (undescended testes), and hypospadias (ventrally displaced urethral meatus). We established a population of 1,073,026 Danish boys born alive between 1 January 1978 and 31 December 2012. By means of Cox regression analyses, we estimated hazard ratios with 95% confidence intervals for cryptorchidism and hypospadias according to type and severity of hypertensive disorder. Further, we used restricted cubic spline analyses to investigate the association between gestational age at onset of severe and moderate preeclampsia and the two genital anomalies. We found associations between pre-gestational hypertension and cryptorchidism [HR: 1.3 (95% CI: 1.1, 1.6)] and hypospadias [HR: 1.7 (95% CI: 1.3, 2.3)], whereas gestational hypertension was only associated with cryptorchidism [HR: 1.2 (95% CI: 1.1, 1.4)]. Boys of mothers with preeclampsia had the highest occurrence of cryptorchidism and hypospadias, increasing with preeclampsia severity. Women with HELLP syndrome faced the highest risk of having a child with both cryptorchidism [HR: 2.1 (95% CI: 1.4, 3.2)] and hypospadias [HR: 3.9 (95% CI: 2.5, 6.1)]. Further, the occurrence increased with early onset of preeclampsia diagnosis. These findings support the hypotheses that preeclampsia and genital anomalies share common etiologic factors and that placental dysfunction and androgen deficiency in early pregnancy are important in the etiology of male genital anomalies.

The post-partum eclampsia occurs usually in the first 48 hours, its incidence is between 13 and 37% of all eclampsia. The goal of this prospective study was to analyse the epidemiologic data and the prognosis of this complication in the post-partum stage. We enrolled between January 1st 2000 to December 31st 2003 all eclampsia admitted to the intensive care unit of the maternity of the university hospital centre Ibn Rochd of Casablanca, Morocco. We noted for each patient epidemiologic, clinical, biological and radiologic data. We releaved outcomoe also. Two groups are individualized: 1) group 1 (N=247): when eclampsia diagnosed in the prepartum stage; 2) group 2 (N=58): when crisis diagnosed in the post-partum stage. We compared the groups (student test), p<0.05 was significative. The incidence of eclampsia in the post-partum in this study was 19% (58 over 305). Eighty-two percent had the crisis in the first 24 hours; we noted a crisis in the sixth, seventh and lately in the sixtieth day. The major proportion of patients are nulliparous (64%), young (mean age: 24 years), without prenatal care, and has high blood pressure (48%), low GCS (mean: 12) and massive proteinuria>3 g/24 hours (37%). The post-partum eclampsia has best out come than these occurring in prepartum, with significantly (p<0.05) less high blood pressure, hellp syndrome and less placental abruption. Eclampsia is still frequent in our service; it seems less bad when occurring in the post-partum stage. We must give more attention for severe preeclamptic patient in this period.

The associations of maternal conditions, before or during pregnancy, with placental lesions have not been adequately studied in populations. In the Boston Birth Cohort, we evaluated associations between three maternal medical conditions (hypertensive disorders [HDs], gestational/pre-gestational diabetes and obesity), and placental histological findings, using a standardized classification system proposed by the Amsterdam Placental Workshop Group. Placental pathology diagnoses and clinical data from 3074 mothers with clinical indications who delivered singleton live births at the Boston Medical Center between October 1998 and November 2013 were evaluated. Associations between each maternal condition and maternal vascular malperfusion (MVM) of the placental bed and its standardized subgroups were examined using multivariate logistic and multinomial regressions. Women with HDs (chronic hypertension, eclampsia, preeclampsia, HELLP syndrome) had significantly increased odds of MVM lesions when compared to women with no HD (aOR 2.08 95% CI 1.74-2.50), after adjusting for demographics, substance use, diabetes and body mass index. No significant differences in frequencies or aORs were seen in women with and without diabetes, or across body mass index categories. Co-morbid condition patterns that included HDs were more likely to be associated with MVM than those without. Using a standardized classification system, we showed that MVM is strongly and specifically associated with maternal HDs, but not other maternal conditions. Additional studies are needed to confirm and validate our findings, and evaluate the role of maternal vascular lesions of the placental bed in relation to postnatal growth and development of the offspring and effect modifiers.

2003-01-01

Conservative treatment in severe preeclampsia has been documented by several authors citing significant improvement in neonatal outcome lacking a significant increase in maternal complications. Our objective was to inform of our preliminary results using protocolized conservative management in women with preeclampsia-eclampsia, favoring better neonate conditions. We included 34 patients with average age of 28.2 years with documented severe preeclampsia-eclampsia complicating a 36-weeks or less pregnancy, admitted in the obstetric intensive care unit (OICU) between October 2001 and February 2002. Patients received protocolized management consisting of intravascular colume expansion, anti-hypertensive control, target organ protection, monitoring, and clinical observation. We considered conservative management as a 24 or more period offered to patients with satisfactory response to medical treatment and no evidence of binomial compromise. Of our group, 85% corresponded to severe preeclampsia, 9% to eclampsia, 3% to imminence of eclampsia, and 3% to HELLP syndrome. Average stay in OICU was 5.5 days with 3.5 days average management before pregnancy was interrupted. These patients presented mean gestational age of 32.8 weeks during which we observed anemia, low platelets, D dimmer increments, MAP average of 112.8, PCOc 18.6, and BI 0.15. We obtained 36 live newborns of whom 12% four died, two were extremely immatures (510 g and 600 g, respectively); one 980-g newborn presented intraventricular hemorrhage, and a 1,450-g newborn had multiple organ failure. Conservative treatment in patients with severe preeclampsia-eclampsia is a feasible alternative in hospitals with an ICU. Conservative management can improve neonatal survival and prognosis in preterm newborns.

A 52-year-old man with Chilaiditi syndrome and mental retardation was admitted to Kanagawa Rehabilitation Hospital for severe hypoglycemic coma with malnutrition. This patient was first diagnosed as partial isolated adrenocorticotropin deficiency according to his symptoms and clinical course, but he was finally diagnosed as preclinical Cushing's syndrome. Manifestations of this case seemed unusual in spite of autonomic cortisol secretion and the detailed mechanisms of symptoms were unclear. The present case indicates that preclinical Cushing's syndrome may present with various manifestations, and careful diagnosis is necessary.

We know little about effective treatment for patients suffering from partial or complete Klüver-Bucy Syndrome (KBS) and other disruptive behaviors following a stroke. Reported cases have shown that certain medication, given alone or combined, can be partially effective. In this specific case study, we will try to demonstrate the effectiveness of a combination of carbamazepine, clonidine, quetiapine and methylphenidate in the alleviating of these symptoms. The wide range of symptoms found in KBS led us to use several kinds of psychotropic medication in spite of the inherent risks associated to polypharmacy.

In Williams Syndrome (WS), a known genetic deletion results in atypical brain function with strengths in face and language processing. We examined how genetic influences on brain activity change with development. In three studies, ERPs from large samples of children, adolescents, and adults with the full genetic deletion for WS were compared to typically developing controls, and two adults with partial deletions for WS. Studies 1 and 2 identified ERP markers of brain plasticity in WS across development. Study 3 suggested that in adults with partial deletions for WS, specific genes may be differentially implicated in face and language processing. PMID:24219698

Follicular cyst of the jaw developing into a keratocyst in a patient with unrecognized Gorlin-Goltz syndrome.

2010-05-01

Gorlin-Goltz (GG) syndrome is an inherited autosomal dominant condition. Its diagnosis may be clinically confirmed by checking either major or minor signs that define the diagnostic criteria. It may occur that, although GG syndrome is a well-known condition, only the specific symptom could be observed by different specialists. Therefore, the patient cannot be placed into an always complex clinical panel. We introduce an example in this report. Throughout a 20-year clinical history characterized by the lack of proper diagnosis and missed follow-up operations, a patient with GG syndrome underwent partial amputation of the jaw after severe complications. A 52-year-old man required an implant-prosthetic rehabilitation since becoming edentulous after a partial resection of the jaw due to a keratocyst, which was later reconstructed through a free fibula flap. The observation of a typical phenotype and various symptoms that succeeded for longer than 20 years, with anamnestic evaluation and clinical examination, led us to suspect a complex pathologic condition such as GG syndrome, which was not previously considered, although the patient had undergone several polyspecialistic evaluations. Diagnosis has been eventually confirmed by a genetic study, which was always mandatory. The simultaneous presence of muscular and skeletal malformations, basocellular nevi, and multiple cysts of the jaw can represent signs linking to a condition such as GG syndrome. There are many syndromes involving the head and neck region, and specialists are supposed to be alerted when faced with similar typical expressions associated with a characteristic soma so as to avoid delays in diagnosing the syndrome.

The new patient with a first seizure.

PubMed

King, Mark

2003-04-01

First seizures are common, with one in 20 people suffering a seizure at some time in their life. This article aims to outline the assessment of patients with a first seizure, including making an accurate diagnosis of both seizure type and an epilepsy syndrome, if present. Seizures are classified into generalised and partial (arising from a focal region in the brain) based on clinical and electroencephalogram findings. However, as a partial seizure may proceed to a tonic clonic phase, differentiation may be difficult. Inquiring directly about 'minor' epileptic symptoms before the episode such as absences, myoclonic jerks, visual or auditory hallucinations or feelings of déjà vu, is needed to attempt to make a epilepsy syndrome diagnosis, as this has practical implications for treatment, prognosis and genetic counselling. Generalised epilepsies should be treated initially with valproate, while partial epilepsies should be treated with carbamazepine and switched to newer agents if intolerance occurs.

Animal model of neuropathic tachycardia syndrome

Carson, R. P.; Appalsamy, M.; Diedrich, A.; Davis, T. L.; Robertson, D.

2001-01-01

Clinically relevant autonomic dysfunction can result from either complete or partial loss of sympathetic outflow to effector organs. Reported animal models of autonomic neuropathy have aimed to achieve complete lesions of sympathetic nerves, but incomplete lesions might be more relevant to certain clinical entities. We hypothesized that loss of sympathetic innervation would result in a predicted decrease in arterial pressure and a compensatory increase in heart rate. Increased heart rate due to loss of sympathetic innervation is seemingly paradoxical, but it provides a mechanistic explanation for clinical autonomic syndromes such as neuropathic postural tachycardia syndrome. Partially dysautonomic animals were generated by selectively lesioning postganglionic sympathetic neurons with 150 mg/kg 6-hydroxydopamine hydrobromide in male Sprague-Dawley rats. Blood pressure and heart rate were monitored using radiotelemetry. Systolic blood pressure decreased within hours postlesion (Delta>20 mm Hg). Within 4 days postlesion, heart rate rose and remained elevated above control levels. The severity of the lesion was determined functionally and pharmacologically by spectral analysis and responsiveness to tyramine. Low-frequency spectral power of systolic blood pressure was reduced postlesion and correlated with the diminished tyramine responsiveness (r=0.9572, P=0.0053). The tachycardia was abolished by treatment with the beta-antagonist propranolol, demonstrating that it was mediated by catecholamines acting on cardiac beta-receptors. Partial lesions of the autonomic nervous system have been hypothesized to underlie many disorders, including neuropathic postural tachycardia syndrome. This animal model may help us better understand the pathophysiology of autonomic dysfunction and lead to development of therapeutic interventions.

Miller Fisher syndrome (MFS) is a variant of Guillan Barre syndrome characterized by the triad of ophthalmoplegia, ataxia and areflexia. Recurrences are exceptional with Miller Fisher syndrome. We are reporting a case with two episodes of MFS within two years. Initially he presented with partial ophthalmoplegia, ataxia. Second episode was characterized by full-blown presentation characterized by ataxia, areflexia and ophthalmoplegia. CSF analysis was typical during both episodes. Nerve conduction velocity study was fairly within normal limits. MRI of brain was within normal limits. He responded to symptomatic measures initially, then to steroids in the second episode. We are reporting the case due to its rarity.

Partial trisomy 14q and monosomy 20q due to an unbalanced familial translocation

Partial trisomy of distal 14q and monosomy of 20q are rare. There have been several reports of a partial distal trisomy 14q with characteristic clinical findings, including hypogonadism and a conotruncal cardiac anomaly. There is no deletion distal 20q syndrome. We have recently examined a newborn with this unique duplication/deletion syndrome. Case report: J.S. was the 2980 gm product of a term uneventful pregnancy delivered to a 24-year-old gravida 2, para 1001 mother. The newborn exam revealed a dysmorphic newborn male with a sloping forehead, bitemporal narrowing, glabellar furrowing and micrognathia. A systolic murmur was audible. The genital abnormalities weremore » micropenis, hypospadias with chordee and bifid scrotum with prominent raphe, and gonads were palpable. A CAT scan of the head revealed grade I IVH. An echocardiogram showed a VSD, ASD and an AP window. A sonogram of the liver showed absence of the gallbladder. Chromosome analysis revealed an abnormal male karyotype containing a derivative 20, subsequently shown to be inherited as a result of malsegregation of a paternal translocation: 46,XY,-20,+der(20)t(14;20)(q32.1;q13.3)pat. The infant fed poorly and required tube feedings and was treated for congestive heart failure with Digoxin, Lasix and oxygen. A decreased cortisol level and cholestasis were noted. The infant died after a cardiopulmonary arrest at one month of age. No post-mortem was obtained. Clinical cytogenetic correlation (conotruncal abnormality and hypogonadism) with partial duplication of distal 14q was positive. This case helps to further delineate duplication 14q and a syndrome due to partial deletion 20q.« less

1999-04-01

Succinate dehydrogenase (SDH) deficiency is rare. Clinical manifestations can appear in infancy with a marked impairment of psychomotor development with pyramidal signs and extrapyramidal rigidity. A 10-month-old boy developed severe neurological features, evoking a Leigh syndrome; magnetic resonance imaging showed features of leukodystrophy. A deficiency in the complex II respiratory chain (succinate dehydrogenase [SDH]) was shown. The course was remarkable by the regression of neurological impairment under treatment by riboflavin. The delay of psychomotor development, mainly involving language, was moderate at the age of 5 years. The relatively good prognosis of this patient, despite severe initial neurological impairment, may be due to the partial enzyme deficiency and/or riboflavin administration.

The purpose of this study was to determine the impact of partial glossectomy (using the keyhole technique) on speech intelligibility, articulation, resonance and oromyofunctional behavior. A partial glossectomy was performed in 4 children with Beckwith- Wiedemann syndrome between the ages of 0.5 and 3.1 years. An ENT assessment, a phonetic inventory, a phonemic and phonological analysis and a consensus perceptual evaluation of speech intelligibility, resonance and oromyofunctional behavior were performed. It was not possible in this study to separate the effects of the surgery from the typical developmental progress of speech sound mastery. Improved speech intelligibility, a more complete phonetic inventory, an increase in phonological skills, normal resonance and increased motor-oriented oral behavior were found in the postsurgical condition. The presence of phonetic distortions, lip incompetence and interdental tongue position were still present in the postsurgical condition. Speech therapy should be focused on correct phonetic placement and a motor-oriented approach to increase lip competence, and on functional tongue exercises and tongue lifting during the production of alveolars. Detailed analyses in a larger number of subjects with and without Beckwith-Wiedemann syndrome may help further illustrate the long-term impact of partial glossectomy. Copyright © 2011 S.

Lynch syndrome is a hereditary cancer syndrome caused by a constitutional mutation in one of the mismatch repair genes. The implementation of predictive testing and targeted preventative surveillance is hindered by the frequent finding of sequence variants of uncertain significance in these genes. We aimed to determine the pathogenicity of previously reported variants (c.-28A>G and c.-7C>T) within the MLH1 5'untranslated region (UTR) in two individuals from unrelated suspected Lynch syndrome families. We investigated whether these variants were associated with other pathogenic alterations using targeted high-throughput sequencing of the MLH1 locus. We also determined their relationship to gene expression and epigenetic alterations at the promoter. Sequencing revealed that the c.-28A>G and c.-7C>T variants were the only potentially pathogenic alterations within the MLH1 gene. In both individuals, the levels of transcription from the variant allele were reduced to 50% compared with the wild-type allele. Partial loss of expression occurred in the absence of constitutional epigenetic alterations within the MLH1 promoter. We propose that these variants may be pathogenic due to constitutional partial loss of MLH1 expression, and that this may be associated with intermediate penetrance of a Lynch syndrome phenotype. Our findings provide further evidence of the potential importance of noncoding variants in the MLH1 5'UTR in the pathogenesis of Lynch syndrome. © 2015 The Authors. **Human Mutation published by Wiley Periodicals, Inc.

We describe a pedigree presenting X-linked severe mental retardation associated with multiple congenital abnormalities and 46,XY gonadal dysgenesis, leading in one family member to female gender assignment. Female carriers are unaffected. The dysmorphic features are similar to those described in the {alpha}-thalassemia and mental retardation (ATR-X) syndrome, although there is no clinical evidence of {alpha}-thalassemia in this family. In addition, the family had other clinical features not previously observed in the ATR-X syndrome, including partial optic-nerve atrophy and partial ocular albinism. Mutations in a putative DNA helicase, termed XH2, have been reported to give rise to the ATR-X syndrome. Wemore » screened the YCH2 gene for mutations in affected members of the family and identified a 4-bp deletion at an intron/exon boundary that removes an invariant 3{prime} splice-acceptor site. The mutation cosegregates with the syndrome. The genomic deletion causes missplicing of the pre-mRNA, which results in the loss of 8 bp of coding sequence, thereby generating a frameshift and a downstream premature stop codon. Our finding increases the range of clinical features associated with mutations in the XH2 gene. 17 refs., 4 figs., 2 tabs.« less

To identify novel genetic causes of syndromic hearing loss in Brazil. To map a candidate chromosomal region through linkage studies in an extensive Brazilian family and identify novel pathogenic variants using sequencing and array-CGH. Brazilian pedigree with individuals affected by BO syndrome characterized by deafness and malformations of outer, middle and inner ear, auricular and cervical fistulae, but no renal abnormalities. Whole genome microarray-SNP scanning on samples of 11 affected individuals detected a multipoint Lod score of 2.6 in the EYA1 gene region (chromosome 8). Sequencing of EYA1 in affected patients did not reveal pathogenic mutations. However, oligonucleotide-array-CGH detected a duplication of 71.8Kb involving exons 4 to 10 of EYA1 (heterozygous state). Real-time-PCR confirmed the duplication in fourteen of fifteen affected individuals and absence in 13 unaffected individuals. The exception involved a consanguineous parentage and was assumed to involve a different genetic mechanism. Our findings implicate this EYA1 partial duplication segregating with BO phenotype in a Brazilian pedigree and is the first description of a large duplication leading to the BOR/BO syndrome.

The most common of the heterogeneous group of the extra structurally abnormal chromosomes (ESACs) is the inv dup(15), whose presence results in tetrasomy 15p and partial tetrasomy 15q. Inv dup(15), containing the Prader-Willi/Angelman syndrome (PWS/AS) region, are constantly associated with phenotypic abnormalities and mental retardation. We report on four additional patients with inv dup(15), whose behavioral pattern, and neurologic and physical findings further delineate the phenotype of this neurogenetic syndrome. We also provide FISH analyses on chromosomes of the observed ESACs and discuss the role of a number of genes located within the tetrasomic region.

A bleeding diathesis is a common feature of Noonan syndrome, and various coagulation abnormalities have been reported. Platelet function has never been carefully investigated. The degree of bleeding diathesis in a cohort of patients with Noonan syndrome was evaluated by a validated bleeding score and investigated with coagulation and platelet function tests. If ratios of prothrombin time and/or activated partial thromboplastin time were prolonged, the activity of clotting factors was measured. Individuals with no history of bleeding formed the control group. The study population included 39 patients and 28 controls. Bleeding score was ≥2 (ie, suggestive of a moderate bleeding diathesis) in 15 patients (38.5%) and ≥4 (ie, suggestive of a severe bleeding diathesis) in 7 (17.9%). Abnormal coagulation and/or platelet function tests were found in 14 patients with bleeding score ≥2 (93.3%) but also in 21 (87.5%) of those with bleeding score <2. The prothrombin time and activated partial thromboplastin time were prolonged in 18 patients (46%) and partial deficiency of factor VII, alone or in combination with the deficiency of other vitamin K-dependent factors, was the most frequent coagulation abnormality. Moreover, platelet aggregation and secretion were reduced in 29 of 35 patients (82.9%, P < .01 for all aggregating agents). Nearly 40% of patients with the Noonan syndrome had a bleeding diathesis and >90% of them had platelet function and/or coagulation abnormalities. Results of these tests should be taken into account in the management of bleeding or invasive procedures in these patients. Copyright © 2014 by the American Academy of Pediatrics.

Dubowitz syndrome is a very rare, autosomal recessive disease characterized by microcephaly, growth retardation, a high sloping forehead, facial asymmetry, blepharophimosis, sparse hair and eyebrows, low-set ears and mental retardation. Symptoms vary between patients, but other characteristics include a soft high-pitched voice, dental and craniofacial abnormalities, partial webbing of the fingers and toes, palate deformations, genital abnormalities, eczema, hyperactivity, preference for concrete over abstract thinking, language difficulties and an aversion to crowds. We describe the craniofacial and dental characteristics of a 12-year-old Caucasian Italian boy with both the typical and less common findings of Dubowitz syndrome. Diagnosis of Dubowitz syndrome is mainly based on the facial phenotype. Possible conditions for differential diagnosis include Bloom syndrome, Smith-Lemli-Opitz syndrome, and fetal alcohol syndrome. As there are few reports of this syndrome in the literature, we hope this case report will enable health professionals to recognize the phenotypic alterations of this syndrome, and allow early referral for the necessary multidisciplinary treatments.

However, in patients with frequent urinary tract infection, it is important to determine any treatable cause to avoid recurrence. Herlyn-Werner-Wunderlich syndrome or OHVIRA syndrome is a very rare congenital anomaly with uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. The earliest presentation of this syndrome is hematocolpos that develops during menstruation and results in dysmenorrhea and a pelvic mass shortly after menarche. Herein, we report a patient with Herlyn-Werner-Wunderlich syndrome manifested with unusual symptoms, delayed onset and without surgery. The unique point of this patient is the partial obstruction of cervico-vaginal junction. Early diagnosis and timely treatment of OHVIRA syndrome can prevent long-term complications, such as recurrent urinary tract infection and infertility. A high index of suspicion is required, even though OHVIRA syndrome is extremely rare and may have an atypical presentation.

Fuhrmann syndrome and the Al-Awadi/Raas-Rothschild/Schinzel phocomelia syndrome are considered to be distinct limb-malformation disorders characterized by various degrees of limb aplasia/hypoplasia and joint dysplasia in humans. In families with these syndromes, we found homozygous missense mutations in the dorsoventral-patterning gene WNT7A and confirmed their functional significance in retroviral-mediated transfection of chicken mesenchyme cell cultures and developing limbs. The results suggest that a partial loss of WNT7A function causes Fuhrmann syndrome (and a phenotype similar to mouse Wnt7a knockout), whereas the more-severe limb truncation phenotypes observed in Al-Awadi/Raas-Rothschild/Schinzel phocomelia syndrome result from null mutations (and cause a phenotype similar to mouse Shh knockout). These findings illustrate the specific and conserved importance of WNT7A in multiple aspects of vertebrate limb development.

Down syndrome is the most common chromosomal abnormality among live-born infants. Through full or partial trisomy of chromosome 21, Down syndrome is associated with cognitive impairment, congenital malformations (particularly cardiovascular) and dysmorphic features. Immune disturbances in Down syndrome account for an enormous disease burden ranging from quality-of-life issues (autoimmune alopecia) to more serious health issues (autoimmune thyroiditis) and life-threatening issues (leukaemia, respiratory tract infections and pulmonary hypertension). Cardiovascular and pulmonary diseases account for ∼75% of the mortality seen in persons with Down syndrome. This review summarises the cardiovascular, respiratory and immune challenges faced by individuals with Down syndrome, and the genetic underpinnings of their pathobiology. We strongly advocate increased comparative studies of cardiopulmonary disease in persons with and without Down syndrome, as we believe these will lead to new strategies to prevent and treat diseases affecting millions of people worldwide.

Turner syndrome is a rare chromosomal disorder with complete or partial absence of one X chromosome that only occurs in women. Clinical presentation is variable, but congenital and acquired cardiovascular diseases are frequently associated diseases that add significantly to the increased morbidity and mortality in Turner syndrome patients. Arterial hypertension is reported in 13-58% of adult Turner syndrome patients and confers an increased risk for stroke and aortic dissection. Hypertension can be present from childhood on and is reported in one-quarter of the paediatric Turner syndrome patients. This article reviews the prevalence and cause of arterial hypertension in Turner syndrome and describes the relationship between blood pressure, aortic dilation and increased cardiovascular risk. We compare current treatment strategies and also propose an integrated practical approach for the diagnosis and treatment of hypertension in Turner syndrome applicable in daily practice.

Partial monosomy 11q is associated with metopic craniosynostosis and trigonocephaly. Prominant features in the over 30 reported cases include downslanting palpebral fissures, epicanthal folds, hypertelorism, ptosis, wide/depressed nasal bridge, low set malformed ears, downturned mouth, micro/retrognathia, digital and cardiac anomalies and psychomotor retardation. We evaluated two patients referred for abnormal head shape. The first carried a diagnosis of Saethre-Chotzen syndrome due to brachycephaly, facial asymmetry, ptosis, cupped ears, sundactyly of 2nd and 3rd digits, developmental delay, and VSD. Karyotype revealed 46,XY,del(11)(q24.1{yields}qter). No abnormality was noted of chromosome 7p, where the Saethre-Chotzen syndrome locus has been mapped. This suggests genetic heterogeneitymore » for this condition. The second patient had no prior diagnosis. He had trigonocephaly, bilateral cryptorchidism and inguinal hernias. He also had hypotelorism, epicanthal folds, synophrys, posteriorly rotated ears, horizontal crease below his lower lip, unilateral single palmar crease, mild soft tissue syndactyly and a shawl scrotum. His karyotype of 46,XY,-11,+der(11)t(4;11)(q31.3;q25) revealed both partial 11q monosomy and partial 4q trisomy (the latter associated with cryptorchidism, horizontal chin crease and single palmar crease). Deletions of 11q appear to produce a wide spectrum of defects, which may even mimic other known craniosynostotic conditions. Study of these patients may lead to the identification of new genes involved in craniofacial morphogenesis.« less

We report on a girl with partial deletion of Xp and partial duplication of 22q. Family studies demonstrate that both the patient's mother and her nonidentical twin sister carry the corresponding balanced translocation; 46,X,t(X;22)(p11.4;q11.2). This girl has developmental delay, microcephaly, mild dysmorphisms and hearing loss but otherwise shows few of the features described in individuals with duplications of the long arm of chromosome 22. She does manifest characteristics, such as short stature and biochemical evidence of ovarian failure, which are seen in partial or complete Xp deletions and Turner's syndrome.

Partial trisomy 16p in an adolescent with autistic disorder and Tourette`s syndrome

Hebebrand, J.; Martin, M.; Remschmidt, H.

A partial trisomy 16p was identified in a 14-year-old male adolescent with autistic disorder. He additionally showed complex motor and vocal phenomena, including some simple tics which had first appeared in childhood. Whereas these simple tics were of subclinical significance, an additional diagnosis of Tourette`s syndrome (TS) appears justified. The case report illustrates the diagnostic difficulties in assessing psychiatric symptomatology associated with both disorders, especially complex motor and vocal phenomena. The cytogenetic finding is discussed critically in the light of other chromosome abnormalities reported in both TS and autistic disorder. Chromosome 16p should be considered as a candidate region especiallymore » for autistic disorder. 21 refs.« less

We describe a French young man with digital anomalies consisting of brachydactyly, F1-5 bilateral camptodactyly, interdigital webbing, F5 bilateral radial clinodactyly, and partial syndactyly of some fingers and toes. He had psychomotor retardation, short stature, umbilical hernia, a secundum atrial septal defect, seizures, hearing impairment, and dysmorphic features consisting of microcephaly, a prominent metopic ridge, upslanting palpebral fissures, synophrys, enophthalmia, large ears, a bulbous nose, a high palate, a smooth and short philtrum, a low hanging columella, a thin upper vermillion, an everted lower lip, prognathism, pectum excavatum, and supernumerary nipples. Osteotendinous reflexes were brisk. Mild nystagmus, myopia, and astigmatia were also noted. Total body X-rays showed short terminal phalanges of the hands, short middle phalanges of the index and little fingers, clinodactyly of the little fingers, short and fused proximal 4th and 5th metacarpals of the right hand, a short 5th metacarpal of the left hand, a fused left lunate-triquetrum, fused capitate-hamates, a prominent mandibula, and partial sacral agenesis. A thin posterior corpus callosum was apparent by MRI. Differential diagnoses for mainly the Rubinstein-Taybi syndrome, the Tsukahara syndrome, the Filippi syndrome, the Feingold syndrome, and the Tonoki syndrome are discussed, and the possibility that we might be reporting a novel entity is raised. © 2011 Wiley-Liss, Inc.

The principal objective of the study is to compare results from the experimental group of pregnant women suffering from thrombocytopenia in pregnancy with results from the control group of pregnant women with normal physiologic blood platelet count. Department of Obstetrics and Gynaecology of the Tomas Bata Regional Hospital Zlín, Obstetrics and Gynaecology Clinic, Haematology and Oncology Clinic of the Palacky University Teaching Hospital and Medical School in Olomouc, Obstetrics and Gynaecology Clinic of the Ostrava Teaching Hospital. A group of 200 pregnant women suffering from thrombocytopenia underwent thorough medical tests. The level of platelets, presence of anti-platelets agents, liver function (LFT), anti-phospholipid antibodies, complete blood count with differential, specific antibodies for hepatitis B and C, Lyme borreliosis and cytomegalovirus were determined from venous blood using the EIA, ELISA methods. Medical articles and books about thrombocytopenia divide the causes for thrombocytopenia as follows: 79.5% benign gestational thrombocytopenia, 16% preeclampsia, 2.5% HELLP syndrome, 1% immune thrombocytopenia, 1% HVC. The number of women who developed physiological anaemia in pregnancy and were overweight is identical in the experimental group of pregnant women suffering from thrombocytopenia and in the control group of pregnant women with normal physiologic blood platelet count, and the proportion of the different age groups in the two groups of pregnant women is also identical. 32% of pregnancies in the experimental group ended in a caesarean section, of which 13.5% in a group of 127 pregnant women suffering from mild thrombocytopenia, 17.5% in a group of 71 pregnant women suffering from moderate thrombocytopenia and 1% in a group of 2 pregnant women suffering from severe thrombocytopenia. 20.5% pregnancies in the control group ended in caesarean section.

Objective It was the aim of our study to evaluate the independent effect of preterm prelabor rupture of membranes (PPROM) as a cause of preterm delivery on mortality during primary hospital stay and significant morbidities in very-low-birth-weight (VLBW) infants < 32 weeks of gestation. Design Observational, epidemiological study design. Setting Population-based cohort, German Neonatal Network (GNN). Population 6102 VLBW infants were enrolled in GNN from 2009-2012, n=4120 fulfilled criteria for primary analysis (< 32 gestational weeks, no pre-eclampsia, HELLP (highly elevated liver enzymes and low platelets syndrome) or placental abruption as cause of preterm birth). Methods Multivariable logistic regression analyses included PPROM as potential risk factors for adverse outcomes and well established items such as gestational age in weeks, birth weight, antenatal steroids, center, inborn delivery, multiple birth, gender and being small-for-gestational-age. Results PPROM as cause of preterm delivery had no independent effect on the risk of early-onset sepsis, clinical sepsis and blood-culture proven sepsis, while gestational age proved to be the most important contributor to sepsis risk. The diagnosis of PPROM was associated with an increased risk for bronchopulmonary dysplasia (BPD; OR: 1.25, 95% CI: 1.02-1.55, p=0.03) but not with other major outcomes. Conclusions The diagnosis of PPROM per se is not associated with adverse outcome in VLBW infants < 32 weeks apart from a moderately increased risk for BPD. Randomized controlled trials with primary neonatal outcomes are needed to determine which subgroup of VLBW infants benefit from expectant or intentional management of PPROM. PMID:25856083

Robust evidence to direct management of pregnant women with mild hypertensive disease at term is scarce. We investigated whether induction of labour in women with a singleton pregnancy complicated by gestational hypertension or mild pre-eclampsia reduces severe maternal morbidity. We undertook a multicentre, parallel, open-label randomised controlled trial in six academic and 32 non-academic hospitals in the Netherlands between October, 2005, and March, 2008. We enrolled patients with a singleton pregnancy at 36-41 weeks' gestation, and who had gestational hypertension or mild pre-eclampsia. Participants were randomly allocated in a 1:1 ratio by block randomisation with a web-based application system to receive either induction of labour or expectant monitoring. Masking of intervention allocation was not possible. The primary outcome was a composite measure of poor maternal outcome--maternal mortality, maternal morbidity (eclampsia, HELLP syndrome, pulmonary oedema, thromboembolic disease, and placental abruption), progression to severe hypertension or proteinuria, and major post-partum haemorrhage (>1000 mL blood loss). Analysis was by intention to treat and treatment effect is presented as relative risk. This study is registered, number ISRCTN08132825. 756 patients were allocated to receive induction of labour (n=377 patients) or expectant monitoring (n=379). 397 patients refused randomisation but authorised use of their medical records. Of women who were randomised, 117 (31%) allocated to induction of labour developed poor maternal outcome compared with 166 (44%) allocated to expectant monitoring (relative risk 0.71, 95% CI 0.59-0.86, p<0.0001). No cases of maternal or neonatal death or eclampsia were recorded. Induction of labour is associated with improved maternal outcome and should be advised for women with mild hypertensive disease beyond 37 weeks' gestation. ZonMw.

Preeclampsia is associated with maternal and neonatal complications. It has been indicated that increased uric acid might have a predictive role on preeclampsia. We aimed to investigate the relationship between the level of uric acid with maternal and neonatal complications in women with preeclampsia. In this cross-sectional study, 160 singleton preeclamptic women at more than 28 wk gestational age were included. Hemoglobin, hematocrit, platelet count, liver and uric acid tests, and maternal and neonatal complications were assessed. The severity of preeclampsia, placental abruption, preterm labor, thrombocytopenia, elevated alanine aminotransferase and aspartate aminotransferase (ALT and AST), HELLP syndrome, eclampsia and required hospitalization in the ICU was considered as the maternal complication. Fetal complications were: small for gestational age (SGA), intrauterine fetal death, hospitalization in the neonatal intensive care unit, and Apgar score <7 at five minutes. Of our participants, 38 women had severe preeclampsia (23.8%). The mean level of uric acid in women with severe preeclampsia was significantly higher than non-severe preeclampsia (p=0.031), also in those with an abnormal liver test (p=0.009). The mean level of uric acid in women with preterm delivery was significantly higher than women with term delivery (p=0.0001). Also, the level of uric acid had no effect on neonatal hospitalization in neonate invasive care unit. Based on logistic regression, the incidence of severe preeclampsia not affected by decreased or increased serum levels of uric acid. With higher level of uric acid in server preeclampsia we can expected more complications such as hepatic dysfunction and preterm delivery. Thus serum uric acid measurement can be helpful marker for severe preeclampsia.

Placental growth and villous maturation are critical parameters of placental function at the end of pregnancy. A failure in these processes leads to the development of placental dysfunction, as well as fetal and neonatal mortality and morbidity. The aim of the study was to determine the relevant diagnostic markers associated with pathological placental development. Forty tissue samples from normal placentas of different gestational age and 68 pathological term placentas with defective villous maturation (GDM, idiopathic IUFD, preeclamsia, HELLP syndrome) comprised the comparative immunohistochemical study (CD15, CD45 and CD34). Positive immunohistochemical reactions were quantitatively assessed in the chorionic plate and vessels of the villi of different histological type. Physiologically immature placentas of the first and second trimester and pathologically immature term placentas were characterized by marked endothelial CD15-immunostaining. A significant loss of CD15-positive endothelium of the placentas was associated with a physiological and accelerated villous maturity. A spatio-temporal correlation was shown for CD15+ endothelial cells (ECs) and the number of CD45+ stromal cells (SCs). A negative temporal correlation was shown for CD15+ ECs and CD15+ myelomonocytes in the fetal blood. CD34 expression in the ECs was stable during the pregnancy. A correlation between a transient CD15-positive endothelial phenotype and a physiological and pathological fetoplacental immaturity was demonstrated. Physiological and accelerated placental maturation was accompanied by a significant disappearance of CD15-positive endothelium. We propose that "immature" CD15+ endothelium is an important diagnostic marker of the physiological and pathological fetoplacental immaturity. Copyright © 2014 Elsevier Ireland Ltd.

Background and Aims Excessive generation of plasminogen activator inhibitor-type 1 (PAI-1) is implicated in the pathogenesis of pre-eclampsia and related conditions. The PAI-1 (−675 4G/5G) promoter polymorphism (rs1799889) affects transcriptional activity and is a putative genetic risk factor for pre-eclampsia. The aim of this study was identify, appraise and synthesise the available evidence for the association of the PAI-1 (−675 4G/5G) polymorphism with pre-eclampsia. Methods Systematic review and random effects meta-analysis of genetic association studies. Results We found 12 eligible genetic association studies in which a total of 1511 women with pre-eclampsia, eclampsia or HELLP syndrome and 3492 controls participated. The studies were generally small (median number of cases 102, range 24 to 403) and underpowered to detect plausible association sizes. Meta-analysis of all of the studies detected statistically significant gene-disease associations in the recessive [pooled odds ratio 1.28 (95% confidence interval 1.09, 1.50); population attributable risk 7.7%] and dominant [pooled odds ratio 1.21 (95% confidence interval 1.01, 1.44); population attributable risk 13.7%] models. We did not find evidence of statistical heterogeneity, funnel plot asymmetry or small study bias. Conclusions These data suggest that the fibrinolytic pathway regulated by the PAI-1 gene may contribute to the pathogenesis of pre-eclampsia and related conditions. This association, if confirmed in larger genetic association studies, may inform research efforts to develop novel interventions or help to prioritise therapeutic targets that merit evaluation in randomised clinical trials.

Hypertensive disorders represent the major cause of maternal morbidity in middle income countries. The main objective of this study was to identify the prevalence and factors associated with severe maternal outcomes in women with severe hypertensive disorders. This was a cross-sectional, multicenter study, including 6706 women with severe hypertensive disorder from 27 maternity hospitals in Brazil. A prospective surveillance of severe maternal morbidity with data collected from medical charts and entered into OpenClinica®, an online system, over a one-year period (2009 to 2010). Women with severe preeclampsia, severe hypertension, eclampsia and HELLP syndrome were included in the study. They were grouped according to outcome in near miss, maternal death and potentially life-threatening condition. Prevalence ratios and 95% confidence intervals adjusted for cluster effect for maternal and perinatal variables and delays in receiving obstetric care were calculated as risk estimates of maternal complications having a severe maternal outcome (near miss or death). Poisson multiple regression analysis was also performed. Severe hypertensive disorders were the main cause of severe maternal morbidity (6706/9555); the prevalence of near miss was 4.2 cases per 1000 live births, there were 8.3 cases of Near Miss to 1 Maternal Death and the mortality index was 10.7% (case fatality). Early onset of the disease and postpartum hemorrhage were independent variables associated with severe maternal outcomes, in addition to acute pulmonary edema, previous heart disease and delays in receiving secondary and tertiary care. In women with severe hypertensive disorders, the current study identified situations independently associated with a severe maternal outcome, which could be modified by interventions in obstetric care and in the healthcare system. Furthermore, the study showed the feasibility of a hospital system for surveillance of severe maternal morbidity.

Epidemiological perinatological nation-wide. 1st Department of Gynaecology and Obstetrics School of Medicine, Comenius University and University Hospital, Bratislava, Slovak Republic. The analysis of selected maternal morbidity and mortality data prospective collected in the years 2007-2012 from all obstetrics hospitals in the Slovak Republic. Caesarean section rate progressively increased from 24.1% in the year 2007 up to 30.3% in the year 2012. In the year 2012 the frequency of vacuum-extraction was 1.4%, forceps 0.6%, perineal tears 3th and 4th degree 0.49% and episiotomy 65%. Incidence of total severe acute maternal morbidity was 6.34 per 1,000 births. Incidence (per 1,000 births) of transport to anaesthesiology department/intensive care unit was 2.32, postpartum hysterectomy 0.72, HELLP syndrome 0.63, eclampsia 0.29, abnormal placental invasion 0.37, uterine rupture 0.27, severe sepsis in pregnancy and puerperium 0.21. In the years 2007-2012 frequency of fatal amniotic fluid embolism was 2.46/100,000 maternities or 2.43/100,000 live-births. Maternal mortality ratio in this period was 14 per 100,000 live births and pregnancy-related deaths ratio was 11.9 per 100,000 live births. In the year 2012 Slovakia reached the highest caesarean section rate in her own history - 30.3%. Incidence of severe acute maternal morbidity was 6.34 per 1,000 births. Maternal mortality ratio in Slovakia was one of the highest in European Union. Decreasing of caesarean section rate and episiotomy, incidence of severe acute maternal morbidity and maternal mortality still need to be improved in Slovak Republic.

Background Preterm delivery is often performed by Caesarean section. We investigated modes of anaesthesia and risk factors for general anaesthesia among women undergoing preterm Caesarean delivery. Methods Women undergoing Caesarean delivery between 24+0 and 36+6 weeks' gestation were identified from a multicentre US registry. The mode of anaesthesia was classified as neuraxial anaesthesia (spinal, epidural, or combined spinal and epidural) or general anaesthesia. Logistic regression was used to identify patient characteristic, obstetric, and peripartum risk factors associated with general anaesthesia. Results Within the study cohort, 11 539 women had preterm Caesarean delivery; 9510 (82.4%) underwent neuraxial anaesthesia and 2029 (17.6%) general anaesthesia. In our multivariate model, African-American race [adjusted odds ratio (aOR)=1.9; 95% confidence interval (CI)=1.7–2.2], Hispanic ethnicity (aOR=1.5; 95% CI=1.2–1.8), other race (aOR=1.4; 95% CI=1.1–1.9), and haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome or eclampsia (aOR=2.8; 95% CI=2.2–3.5) were independently associated with receiving general anaesthesia for preterm Caesarean delivery. Women with an emergency Caesarean delivery indication had the highest odds for general anaesthesia (aOR=3.5; 95% CI=3.1–3.9). For every 1 week decrease in gestational age at delivery, the adjusted odds of general anaesthesia increased by 13%. Conclusions In our study cohort, nearly one in five women received general anaesthesia for preterm Caesarean delivery. Although potential confounding by unmeasured factors cannot be excluded, our findings suggest that early gestational age at delivery, emergent Caesarean delivery indications, hypertensive disease, and non-Caucasian race or ethnicity are associated with general anaesthesia for preterm Caesarean delivery.

Genetic testing of tumor susceptibility genes is now recommended in most patients with pheochromocytoma or paraganglioma (PPGL), even in the absence of a syndromic presentation. Once a mutation is diagnosed there is rarely follow-up validation to assess the possibility of misdiagnosis. This study prospectively examined the prevalence of von Hippel-Lindau (VHL) gene mutations among 182 patients with non-syndromic PPGLs. Follow-up in positive cases included comparisons of biochemical and tumor gene expression data in 64 established VHL patients, with confirmatory genetic testing in cases with an atypical presentation. VHL mutations were detected by certified laboratory testing in 3 of the 182 patients with non-syndromic PPGLs. Two of the 3 had an unusual presentation of diffuse peritoneal metastases and substantial increases in plasma metanephrine, the metabolite of epinephrine. Tumor gene expression profiles in these 2 patients also differed markedly from those associated with established VHL syndrome. One patient was diagnosed with a partial deletion by Southern blot analysis and the other with a splice site mutation. Quantitative polymerase chain reaction, multiplex ligation-dependent probe amplification, and comparative genomic hybridization failed to confirm the partial deletion indicated by certified laboratory testing. Analysis of tumor DNA in the other patient with a splice site alteration indicated no loss of heterozygosity or second hit point mutation. In conclusion, VHL germline mutations represent a minor cause of non-syndromic PPGLs and misdiagnoses can occur. Caution should therefore be exercised in interpreting positive genetic test results as the cause of disease in patients with non-syndromic PPGLs. © Georg Thieme Verlag KG Stuttgart · New York.

Mirizzi syndrome, known as extrinsic bile compression syndrome, is a rare complication of cholecystitis and chronic cholelithiasis, secondary to the obliteration of the infundibulum of the gallbladder or cystic duct caused by the impact of one or more calculations in these anatomical structures, which leads to compression of the adjacent bile duct, resulting in partial or complete obstruction of the common hepatic duct, triggering liver dysfunction. Our aim is to identify and describe the current epidemiology, diagnostic methods, and treatment of Mirizzi syndrome. A literature search was performed using different databases, including Medline, Cochrane, Embase, Medscape, PubMed, using keywords: Mirizzi syndrome, epidemiology, markers, pathophysiology, clinical presentation, diagnosis, and treatment. Selected original articles, review articles or case reports from 1997 to 2015 were collected, written in English or Spanish. The endoscopic retrograde cholangiopancreatography (ERCP) is the most accurate diagnostic method. The traditional treatment has been surgery and involves an incision at the bottom of the gallbladder and calculus removal. If fistulas are observed, it is performed a partial cholecystectomy; otherwise, a cholecystocholedochoduodenostomy is an alternative. Endoscopic treatment includes biliary drainage and stone extraction. Many surgeons claim that laparoscopic cholecystectomy is contraindicated in Mirizzi syndrome because of the presence of inflammatory tissue and adhesions in the Calot’s triangle. If dissection is attempt, it can cause unnecessary injury to the bile duct. However, other surgeons consider the laparoscopic approach is feasible, although technically challenging. Currently, laparoscopic cholecystectomy for this condition is considered controversial and technically challenging; however, it has shown that with the right skills and equipment, it is a safe and feasible way to treat some cases of Mirizzi syndrome type I and II.

There is limited information about risk factors of young ischemic stroke in Qatar. The aim of this study was to describe the risk factors and subtypes of young ischemic stroke among Qatari and non-Qatari residents. Hospital based prospective observational study involving all young adults (15-45 years of age) admitted to Hamad General Hospital with first-ever ischemic stroke from September 2004 to September 2005. A stroke was defined according to WHO criteria. Stroke was confirmed in 40 (32 males and 8 females). Their ages ranged from 17 to 44 years (mean 37.1+/-13.27). Thirty (75%) of the patients were non-Qatari. The most common risk factors were hypertension 16 (40%), diabetes mellitus 13 (32.5%), hypercholesterolemia 11 (27.5%), smoking 11 (27.5%), and alcohol intake 9 (22.5%). Regarding stroke subtypes, lacunar stroke syndrome (LACS) was diagnosed in 17 (42.5%), total anterior circulation stroke syndrome (TACS) in 16 (40%), partial anterior circulation stroke syndrome (PACS) in 5 (12.5%) and posterior circulation stroke syndrome (POCS) in 2 (5%). Partial anterior circulation stroke syndrome (PACS) was observed with a higher frequency in Qatari patients compared with non-Qataris (p=0.009), whereas total anterior circulation stroke syndrome (TACS) was observed more in non-Qatari than in Qatari patients (p=0.03). Average hospital stay was 18 days. In-hospital mortality was 2.5%. The risk factors of ischemic stroke in young adults are numerous. The most common were hypertension, diabetes mellitus, hypercholesterolemia, smoking and alcohol intake. Only one Indonesian male patient with POCS died in the hospital.

We report a case of cerebral deep venous thrombosis that manifested clinically by a pseudobulbar syndrome with major trismus, abnormal movements and static cerebellar syndrome. To our knowledge, only three other cases of deep cerebral venous thrombosis associated with cerebellar or pseudobulbar syndrome have been published since 1985. The relatively good prognosis in our patient could be explained by the partially intact internal cerebral veins as well as use of early anticoagulant therapy. There was a spontaneous hyperdensity of the falx cerebri and the tentorium cerebelli on the brain CT scan, an aspect highly contributive to diagnosis. This hyperdensity of the falx cerebri was found in 19 out of 22 cases of deep venous thrombosis detailed in the literature.

Cushing's syndrome occurred in 1-5% of cases of bronchial carcinoids. In this paper we describe a case of typical bronchial carcinoid in a nonsmoker young male with clinical manifestations mimicking a Cushing's syndrome. The patient performed chest radiograph and computed tomography. Fiberoptic bronchoscopy revealed the presence of an endobronchial mass occluding the bronchus intermedius. A rigid bronchoscopy was necessary for the conclusive diagnosis and for partial resection of the intraluminal tumor. Despite of the presence of Cushingoid features, the normal blood levels of ACTH and cortisol excluded the coexistence of a Cushing's syndrome. Copyright © 2016 The Authors.

Febuxostat is a xanthine oxidase inhibitor that during the last years has successfully replaced allopurinol treatment in patients with chronic kidney disease (CKD) and hyperuricemia. Several adverse events have been observed during therapy with febuxostat. DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) syndrome induced by febuxostat has been poorly described, mainly in patient with CKD who previously developed allopurinol hypersensitivity syndrome. DRESS syndrome is characterized by manifold cutaneous reactions and systemic disorders with potential devastating consequences. The underlying pathogenetic mechanisms remain unidentified, though immune responses are often complicated. P-i concept can partially explain the phenomenon. The role of renal insufficiency appears to be crucial and further investigation is required. The present article describes the case of a CKD patient that developed febuxostat-related DRESS syndrome.

Plant-derived therapeutics for the treatment of metabolic syndrome.

2010-10-01

Metabolic syndrome is defined as a set of coexisting metabolic disorders that increase an individual's likelihood of developing type 2 diabetes, cardiovascular disease and stroke. Medicinal plants, some of which have been used for thousands of years, serve as an excellent source of bioactive compounds for the treatment of metabolic syndrome because they contain a wide range of phytochemicals with diverse metabolic effects. In order for botanicals to be effectively used against metabolic syndrome, however, botanical preparations must be characterized and standardized through the identification of their active compounds and respective modes of action, followed by validation in controlled clinical trials with clearly defined endpoints. This review assesses examples of commonly known and partially characterized botanicals to describe specific considerations for the phytochemical, preclinical and clinical characterization of botanicals associated with metabolic syndrome.

DNA replication precisely duplicates the genome to ensure stable inheritance of genetic information. Impaired licensing of origins of replication during the G1 phase of the cell cycle has been implicated in Meier-Gorlin syndrome (MGS), a disorder defined by the triad of short stature, microtia, and a/hypoplastic patellae. Biallelic partial loss-of-function mutations in multiple components of the pre-replication complex (preRC; ORC1, ORC4, ORC6, CDT1, or CDC6) as well as de novo stabilizing mutations in the licensing inhibitor, GMNN, cause MGS. Here we report the identification of mutations in CDC45 in 15 affected individuals from 12 families with MGS and/or craniosynostosis. CDC45 encodes a component of both the pre-initiation (preIC) and CMG helicase complexes, required for initiation of DNA replication origin firing and ongoing DNA synthesis during S-phase itself, respectively, and hence is functionally distinct from previously identified MGS-associated genes. The phenotypes of affected individuals range from syndromic coronal craniosynostosis to severe growth restriction, fulfilling diagnostic criteria for Meier-Gorlin syndrome. All mutations identified were biallelic and included synonymous mutations altering splicing of physiological CDC45 transcripts, as well as amino acid substitutions expected to result in partial loss of function. Functionally, mutations reduce levels of full-length transcripts and protein in subject cells, consistent with partial loss of CDC45 function and a predicted limited rate of DNA replication and cell proliferation. Our findings therefore implicate the preIC as an additional protein complex involved in the etiology of MGS and connect the core cellular machinery of genome replication with growth, chondrogenesis, and cranial suture homeostasis.

1996-01-01

This study examined group differences in language and pragmatic functions across sex-, age- and IQ-matched samples of Asperger syndrome (N = 22), high-functioning autism (N = 11), deficits in attention, motor control and perception (DAMP) (N = 11), and speech and language disorder (SLD) (N = 11) groups. The purpose was to explore possible differentiating features in the fields of vocabulary, comprehension and pragmatics and, in addition, to determine whether Asperger syndrome could be reliably separated from high-functioning autism on these variables. The findings suggest that Asperger syndrome may be associated with higher full-scale and verbal IQ than high-functioning autism; Asperger syndrome may not be associated with better pragmatic skills (as defined in this context) than high-functioning autism; language comprehension may not clearly separate Asperger syndrome and high-functioning autism once the effects of very low IQ are partialled out; both DAMP and SLD can be distinctly separated from Asperger syndrome and autism.

Signs and genetics of rare cancer syndromes with gastroenterological features

PubMed Central

Bruno, William; Fornarini, Giuseppe; Ghiorzo, Paola

2015-01-01

Although the genetic bases of most hereditary cancer syndromes are known, and genetic tests are available for them, the incidence of the most rare of these syndromes is likely underestimated, partially because the clinical expression is neither fully understood nor easily diagnosed due to the variable and complex expressivity. The clinical features of a small pool of rare cancer syndromes include gastroenterological signs, though not necessarily tumors, that could require the intervention of a gastroenterologist during any of the phases of the clinical management. Herein we will attempt to spread the knowledge on these rare syndromes by summarizing the phenotype and genetic basis, and revising the peculiar gastroenterological signs whose underlying role in these rare hereditary cancer syndromes is often neglected. Close collaboration between geneticists and gastroenterologists could facilitate both the early identification of patients or relatives at-risk and the planning of multidisciplinary and tailored management of these subjects.

We report on a de novo 0.5 Mb triplication (partial tetrasomy) of chromosome 17q25.3 in a 10-year-old girl with severe intellectual disability, infantile seizures (West syndrome), moderate hearing loss, Dandy-Walker malformation, microcephaly, craniofacial dysmorphism, striking cutaneous syndactyly (hands 3-4, feet 2-3), joint laxity, and short stature. The triplication resulted from the unusual combination of a terminal duplication at 17qter and a cryptic translocation of an extra copy of the same segment onto chromosome 10qter. The breakpoint at 17q25.3 was located within the FOXK2 gene. SNP chip analysis suggested that the rearrangement occurred during paternal meiosis involving both paternal chromosomes 17. © 2013 Wiley Periodicals, Inc.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare syndrome characterized by complete or partial agenesis of the uterus and vagina, due to a congenital defect of the Mullerian duct. Affected individuals have a 46,XX karyotype and a normal female phenotype. MRKH syndrome may be isolated (type I MRKH syndrome) or associated with renal, cardiac, and skeletal anomalies, short stature, and auditory defects. The latter is defined as type II MRKH syndrome or the Müllerian duct aplasia/hypoplasia, renal agenesis/ectopy, and cervicothoracic somite dysplasia (MURCS) association. The majority of patients with MRKH syndrome present with primary amenorrhea. We report a case of type II MRKH syndrome who has been referred by a pediatric surgeon for detection of gonadal function. During an inguinal hernia operation, the left ovary had been observed in the hernia sac. Clinical and radiological evaluation of the patient showed an absence of the uterus and left kidney, and cervical hemi vertebra. Based on these findings, the patient was diagnosed as having type II MRKH syndrome.

Williams Syndrome and 15q Duplication: Coincidence versus Association.

Williams syndrome is a multisystem disorder caused by contiguous gene deletion in 7q11.23, commonly associated with distinctive facial features, supravalvular aortic stenosis, short stature, idiopathic hypercalcemia, developmental delay, joint laxity, and a friendly personality. The clinical features of 15q11q13 duplication syndrome include autism, mental retardation, ataxia, seizures, developmental delay, and behavioral problems. We report a rare case of a girl with genetically confirmed Williams syndrome and coexisting 15q duplication syndrome. The patient underwent treatment for central precocious puberty and later presented with primary amenorrhea. The karyotype revealed 47,XX,+mar. FISH analysis for the marker chromosome showed partial trisomy/tetrasomy for proximal chromosome 15q (15p13q13). FISH using an ELN -specific probe demonstrated a deletion in the Williams syndrome critical region in 7q11.23. To our knowledge, a coexistence of Williams syndrome and 15q duplication syndrome has not been reported in the literature. Our patient had early pubertal development, which has been described in some patients with Williams syndrome. However, years later after discontinuing gonadotropin-releasing hormone analogue treatment, she developed primary amenorrhea.

The human deafness-pigmentation syndromes, Waardenburg syndrome (WS) type 2a, and Tietz syndrome are characterized by profound deafness but only partial cutaneous pigmentary abnormalities. Both syndromes are caused by mutations in MITF. To illuminate differences between cutaneous and otic melanocytes in these syndromes, their development and survival in heterozygous Microphthalmia-White (Mitf(Mi-wh) /+) mice were studied and hearing function of these mice characterized. Mitf(Mi-wh) /+ mice have a profound hearing deficit, characterized by elevated auditory brainstem response thresholds, reduced distortion product otoacoustic emissions, absent endocochlear potential, loss of outer hair cells, and stria vascularis abnormalities. Mitf(Mi-wh) /+ embryos have fewer melanoblasts during embryonic development than their wild-type littermates. Although cochlear melanocytes are present at birth, they disappear from the Mitf(Mi-wh) /+ cochlea between P1 and P7. These findings may provide insight into the mechanism of melanocyte and hearing loss in human deafness-pigmentation syndromes such as WS and Tietz syndrome and illustrate differences between otic and follicular melanocytes. © 2012 John Wiley & Sons A/S.

Behavioral phenotypes of genetic syndromes with intellectual disability: comparison of adaptive profiles.

2011-10-30

The study of distinctive and consistent behaviors in the most common genetic syndromes with intellectual disability is useful to explain abnormalities or associated psychiatric disorders. The behavioral phenotypes revealed outcomes totally or partially specific for each syndrome. The aim of our study was to compare similarities and differences in the adaptive profiles of the five most frequent genetic syndromes, i.e. Down syndrome, Williams syndrome, Angelman syndrome, Prader-Willi syndrome, and Fragile-X syndrome (fully mutated), taking into account the relation with chronological age and the overall IQ level. The research was carried out using the Vineland Adaptive Behavior Scale (beside the Wechsler Intelligence scales to obtain IQ) with a sample of 181 persons (107 males and 74 females) showing genetic syndromes and mental retardation. Syndrome-based groups were matched for chronological age and mental age (excluding the Angelman group, presenting with severe mental retardation). Similarities and differences in the adaptive profiles are described, relating them to IQs and maladaptive behaviors. The results might be useful in obtaining a global index of adjustment for the assessment of intellectual disability level as well as for educational guidance and rehabilitative plans.

Rett syndrome is a severe neurodevelopmental disease caused by mutations in the X-linked gene encoding for the methyl-CpG-binding protein MeCP2. Here, we report the identification of FOXG1-truncating mutations in two patients affected by the congenital variant of Rett syndrome. FOXG1 encodes a brain-specific transcriptional repressor that is essential for early development of the telencephalon. Molecular analysis revealed that Foxg1 might also share common molecular mechanisms with MeCP2 during neuronal development, exhibiting partially overlapping expression domain in postnatal cortex and neuronal subnuclear localization.

2007-01-01

Contemporary experience and results of clinical trials concerning dopamine agonist application in the treatment of many different diseases (apart from Parkinson's disease) are presented in the paper. A basic clinical recommendation for agonists is restless legs syndrome. In this syndrome almost all agonists give a considerable subjective and objective improvement. Treatment of atypical parkinsonism (MSA, PSP, CBD) in the majority of patients is ineffective. The author also presents promising results of treatment with agonists in such diverse diseases as hyperkinetic syndromes, cocaine dependence, drug-resistant depression and erectile dysfunction (apomorphine). Dopamine partial agonists (e.g. aripiprazol) are recommended in the modern treatment of schizophrenia.

The authors report an exceptional case of an anterior horn syndrome associated with Sjögren's syndrome in a 58-year-old patient with a flaccid tetraparesis revealed by asymmetric atrophy and diffuse fasciculations associated with xerostomia and xerophthalmia. The electroneuromyography objectified a diffuse anterior horn syndrome. The brain MRI and spinal cord were normal. Laboratory tests revealed positive anti-SSA and anti-SSB antibody. The salivary glands biopsy objectified lymphocytic sialadenitis grade 3 of Chisholm. The Schirmer's test was abnormally low. Diagnosis of anterior horn syndrome as part of Sjögren's syndrome was retained. The methylprednisolone bolus allowed partial clinical improvement after 12 months of evolution. Therefore, in patients with isolated anterior horn involvement, a correct diagnosis of the underlying SS is often delayed or overlooked entirely; in these instances, standard clinicoserological assessment is recommendable.

A cognitive characterization of dyscalculia in Turner syndrome.

2004-01-01

Current theories of number processing postulate that the human abilities for arithmetic are based on cerebral circuits that are partially laid down under genetic control and later modified by schooling and education. This view predicts the existence of genetic diseases that interfere specifically with components of the number system. Here, we investigate whether Turner syndrome (TS) corresponds to this definition. TS is a genetic disorder which affects one woman in 2500 and is characterized by partial or complete absence of one X chromosome. In addition to well-characterized physical and hormonal dysfunction, TS patients exhibit cognitive deficits including dyscalculia. We tested 12 women with Turner syndrome and 13 control subjects on a cognitive battery including arithmetical tests (addition, subtraction, multiplication, division) as well as tests of the understanding of numerosity and quantity (cognitive estimation, estimation, comparison, bisection, subitizing/counting). Impairments were observed in cognitive estimation, subitizing, and calculation. We examine whether these deficits can be attributed to a single source, and discuss the possible implications of hormonal and genetic factors in the neuropsychological profile of TS patients.

Poland's syndrome is a rare unilateral congenital anomaly characterized by the absence of the pectoral muscle and hand anomalies. By the time, new components including the absence or hypoplasia of many muscles have been identified, however, the anomalies of trapezius muscle have not been reported in patients with Poland's syndrome. The accepted etiological theory is the temporary interruption of blood supply of the subclavian artery and its branches in the early gestational period. The artery of the trapezius muscle is also one of the branches of subclavian artery. Just because of that, it is likely to trapezius muscle be affected in patients with Poland's syndrome. We are presenting a case of Poland's syndrome associated with unilateral partial absence of trapezius muscle to support this hypothesis. Copyright © 2014 Elsevier Ltd. All rights reserved.

Coping, affect, and the metabolic syndrome in older men: how does coping get under the skin?

The metabolic syndrome is a complex construct with interrelated factors of obesity, blood pressure, lipids, and glucose. It is a risk factor for a number of chronic diseases in late life. This study tested a model in which the relationship between stress and the metabolic syndrome was mediated by appraisal, coping, and affect. Data were collected from 518 male participants in the Normative Aging Study (X(age) = 68.17 years). The model was partially confirmed. Relationships among stress, appraisal, coping, and affect were valenced along positive and negative pathways. However, affect was not directly related to the metabolic syndrome. The metabolic syndrome was related to positive coping as operationalized by self-regulatory strategies. The results of this study suggest that the influence of coping on physical health may occur through emotional regulation.

Partial trisomy 11q was detected in an infant delivered 3-4 weeks prematurely. The phenotype included slanted palpebral fissures, high arched palate, developmental delay, microcephaly, and cardiac defects, all of which occur in the majority of cases with this syndrome. Other features included a column-shaped skull, preauricular pit, single palmar crease, short, broad great toes, flat occiput, unilateral kidney agenesis, and strabismus. Chromosomes obtained from peripheral blood cells revealed the presence of extra material on the long arm of chromosome 1. The G-banding pattern of this extra material indicated that it might be derived from chromosome 1 or 11. Chromosomal {open_quotes}paints{close_quotes}more » showed that it was not chromosome 1 material, but was chromosome 11 material extending from band q21 to qter.

Laminopathies (diseases related to A/C mutations of lamines) are rare genetic diseases with an extensive phenotypic spectrum, including lipodystrophic syndromes-characterized by a selective loss of adipose tissue-of which the partial Dunnigan family type is the most frequent. We report on a 55-year-old woman with diabetes and long-term disabling myalgia. Her cushingoid morphotype, associated with cutaneous lipo-atrophy and muscle hypertrophy in addition to a genetic heritage, led us to the diagnosis of complex partial familial lipodystrophy heterozygous LMNA_c.82C>T, p.Arg28Trp mutation. Familial partial lipodystrophic syndromes may have varied phenotypes, mainly cardio-metabolic, which could mimic a particularly severe type 2 diabetes. The diagnostic work-up of this disease has to include a careful investigation of gait troubles and paroxysmal conduction that could lead to sudden death, as well as a genetic examination. In some cases, recombinant leptin can be proposed. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

Modeling Monogenic Human Nephrotic Syndrome in the Drosophila Garland Cell Nephrocyte.

PubMed

2017-05-01

Steroid-resistant nephrotic syndrome is characterized by podocyte dysfunction. Drosophila garland cell nephrocytes are podocyte-like cells and thus provide a potential in vivo model in which to study the pathogenesis of nephrotic syndrome. However, relevant pathomechanisms of nephrotic syndrome have not been studied in nephrocytes. Here, we discovered that two Drosophila slit diaphragm proteins, orthologs of the human genes encoding nephrin and nephrin-like protein 1, colocalize within a fingerprint-like staining pattern that correlates with ultrastructural morphology. Using RNAi and conditional CRISPR/Cas9 in nephrocytes, we found this pattern depends on the expression of both orthologs. Tracer endocytosis by nephrocytes required Cubilin and reflected size selectivity analogous to that of glomerular function. Using RNAi and tracer endocytosis as a functional read-out, we screened Drosophila orthologs of human monogenic causes of nephrotic syndrome and observed conservation of the central pathogenetic alterations. We focused on the coenzyme Q 10 (CoQ 10 ) biosynthesis gene Coq2 , the silencing of which disrupted slit diaphragm morphology. Restoration of CoQ 10 synthesis by vanillic acid partially rescued the phenotypic and functional alterations induced by Coq2 -RNAi. Notably, Coq2 colocalized with mitochondria, and Coq2 silencing increased the formation of reactive oxygen species (ROS). Silencing of ND75 , a subunit of the mitochondrial respiratory chain that controls ROS formation independently of CoQ 10 , phenocopied the effect of Coq2 -RNAi. Moreover, the ROS scavenger glutathione partially rescued the effects of Coq2 -RNAi. In conclusion, Drosophila garland cell nephrocytes provide a model with which to study the pathogenesis of nephrotic syndrome, and ROS formation may be a pathomechanism of COQ2 -nephropathy.

We performed a preliminary search of the PubMed and Embase databases using the search terms "snapping scapula," "scapulothoracic bursitis," "partial scapulectomy," and "superomedial angle resection" in September 2013. All nonreview articles related to the topic of snapping scapula syndrome were included. The search identified a total of 167 unique articles, 81 of which were relevant to the topic of snapping scapula syndrome. There were 36 case series of fewer than 10 patients, 16 technique papers, 11 imaging studies, 9 anatomic studies, and 9 level IV outcomes studies. The level of evidence obtained from this literature search was inadequate to perform a formal systematic review or meta-analysis. Therefore, a critical review of current evidence is presented. Snapping scapula syndrome, a likely underdiagnosed condition, can produce significant shoulder dysfunction in many patients. Because the precise origin is typically unknown, specific treatments that are effective for some patients may not be effective for others. Nevertheless, bursectomy with or without partial scapulectomy is currently the most effective primary method of treatment in patients who fail nonoperative therapy. However, many patients experience continued shoulder disability even after surgical intervention. Future studies should focus on identifying the modifiable factors associated with poor outcomes after operative and nonoperative management for snapping scapula syndrome in an effort to improve clinical outcomes and patient satisfaction. © 2014 The Author(s).

Endogenous Cushing's syndrome (CS), a rare endocrine disorder characterized by cortisol hypersecretion, is associated with psychiatric and neurocognitive disorders. Major depression, mania, anxiety, and neurocognitive impairment are the most important clinical abnormalities. Moreover, patients most often complain of impairment in quality of life, interference with family life, social, and work performance. Surprisingly, after hypercortisolism resolution, despite the improvement of the overall prevalence of psychiatric and neurocognitive disorders, the brain volume loss at least partially persists and it should be noted that some patients may still display depression, anxiety, panic disorders, and neurocognitive impairment. This brief review aimed at describing the prevalence of psychiatric and neurocognitive disorders and their characterization both during the active and remission phases of CS. The last section of this review is dedicated to quality of life, impaired during active CS and only partially resolved after resolution of hypercortisolism. PMID:25941467

A girl with mild psychomotor developmental delay developed right or left hemiclonic convulsion at 10months of age. One month later, clusters of hemiclonic or bilateral tonic seizures with eyelid twitching emerged, resulting in status epilepticus. Treatment with phenobarbital and potassium bromide completely terminated the seizures within 10days. Ictal electroencephalography revealed a migrating focus of rhythmic 3-4Hz waves from the right temporal to right frontal regions and then to the left frontal regions. Genetic analysis was conducted based on the characteristic facial appearance of the patient, which identified a 2.1-Mb terminal deletion on chromosome 4p. This is the first case of Wolf-Hirschhorn syndrome complicated by epilepsy with migrating partial seizures. Copyright © 2016 The Japanese Society of Child Neurology. Published by Elsevier B.V.

To describe the natural history of phenotype, growth and gonadal function in patients with partial androgen insensitivity syndrome. Tertiary paediatric endocrine centre. Retrospective evaluation of 14 male patients with partial androgen insensitivity syndrome (PAIS) with verified androgen receptor (AR) mutations. The authors recorded phenotypic characteristics at birth and external masculinisation score (EMS), registered longitudinal growth, circulating levels of testosterone, estradiol, luteinising hormone (LH), follicle-stimulating hormone (FSH), inhibin-B and sex hormone binding globulin (SHBG), in addition to phenotype at postpubertal follow up. The EMS ranged from 5 to 12 in PAIS at birth. Six patients were born with hypospadias and all patients developed gynaecomastia in puberty. Eight of the patients received testosterone treatment. At follow-up penile size was impaired irrespective of EMS at birth, but responded to pubertal androgen therapy in some of the patients. Serum levels of testosterone, estradiol, SHBG and LH, but not FSH and inhibin B, were markedly elevated in puberty. Final height was 181.3 cm (165.7-190.5 cm) corresponding to an SD score of 0.7 (-2.1 to +2.1 SD, n=10). Gynaecomastia and impaired phallic growth are frequently observed in adults with PAIS, but may be ameliorated by androgen therapy. The authors suggest that male patients presenting with gynaecomastia in puberty, and elevated circulating levels of testosterone, estradiol and LH in puberty, but normal FSH, should be suspected of having PAIS and undergo genetic testing for AR mutations.

To explore the efficacy of partial resection of puborectalis combined with mutilation of internal anal sphincter(IAS) in the treatment of puborectalis syndrome with high anal pressure. Twenty-five cases of puborectalis syndrome with high anal resting pressure in the preoperative examination received the operation of partial resection of puborectalis combined with mutilation of IAS in Zhongnan Hospital of Wuhan University between January 2013 and May 2015. The position of puborectalis was confirmed by touching with the exposure under the transfixion device, and a transverse incision was made by electrotome between 3 and 5 o'clock direction of puborectalis, then partial puborectalis was lifted by vessel clamp at 5 o'clock direction, and about 0.5 cm of muscular tissue was resected. Between 8 to 10 o'clock direction of anal tube, about 1 cm length of transverse incision was made by electrotome, then partial IAS was lifted by vessel clamp and cut off. Preoperative and postoperative 3-month anorectal manometry and defecography were carried out. Wexner constipation score and Cleveland Clinic incontinence score were implemented before surgery and 3, 6, 12 months after operation. This study was registered in the Chinese Clinical Trial Registry (registration number: ChiCTR-ORB-16007695). Of the 25 cases, 18 were male and 7 were female, the average age was 55 years old and the average course of disease was 9 years. Compared with pre-operation, the postoperative 3-month anal resting pressure and maximal squeeze pressure were significantly decreased [(53.56±9.05) mmHg vs. (92.44±7.06) mmHg, (142.80±20.35) mmHg vs. (210.88±20.56) mmHg, respectively, both P=0.000]; anorectal angulation at resting state and forced defecation state increased significantly [(102.32±4.96)degree vs. (95.88±4.01)degree, (117.88±5.95)degree vs. (89.52±3.25)degree, respectively, both P=0.000]. Wexner constipation score of postoperative 3-month, 6-month, 12-month (8.28±3.91, 7.40±3.64 and 8.04±4.74) was significantly lower than the preoperative score (16.00±3.69, all P<0.05), while the score was not significantly different among 3 time points after operation (P>0.05). Cleveland Clinic incontinence score was 0 at postoperative 6 and 12 months, and revealed 20 cases were effective among all the surgical patients(80%). Partial resection of puborectalis combined with mutilation of internal anal sphincter can effectively reduce anal pressure and improve symptoms of outlet obstruction, which is an effective method in the treatment of puborectalis syndrome with high anal pressure.

Diagnosing lynch syndrome in absence of colorectal cancer.

PubMed

Lynch, Henry T; Knezetic, Joseph; Lanspa, Stephen

2012-11-01

There are many ways in which a diagnosis of Lynch syndrome can be made, most prominent of which is family history, presence of cancer, high microsatellite instability, immunohistochemistry, and a mismatch repair germline mutation. There are at least four molecular pathways for colorectal cancer carcinogenesis: 1) adenoma-carcinoma sequence; 2) hereditary microsatellite instability; 3) serrated pathway; 4) epidermal growth factor receptor. The answer to diagnosing Lynch syndrome in the absence of colorectal cancer may be partially based upon the phenotypic characteristics of the colonic polyps should they be identified at colonoscopy, specifically their phenotypic characteristics of location, size, histology, number, and age of polyp onset.

Morbidity of Cushing's Syndrome and Impact of Treatment.

Webb, Susan M; Valassi, Elena

2018-06-01

Cortisol excess in Cushing's syndrome is associated with metabolic, cardiovascular, and cognitive alterations, only partially reversible after resolution of hypercortisolism. Elevated cardiovascular risk may persist after eucortisolism has been achieved. Fractures and low bone mineral density are also described in Cushing's syndrome in remission. Hypercortisolism may induce irreversible structural and functional changes in the brain, leading to neuropsychiatric disorders in the active phase of the disease, which persist. Sustained deterioration of the cardiovascular system, bone remodeling, and cognitive function along with neuropsychological impairment are associated with high morbidity and poor quality of life before and after remission.

1994-09-01

In an effort to identify regions on chromosome 18 that may be critical in the appearance of the Edwards syndrome phenotype, the authors have analyzed six patients with partial duplication of chromosome 18. Four of the patients have duplications involving the distal half of 18q (18q21.1-qter) and are very mildly affected. The remaining two patients have most of 18q (18q12.1-qter) duplicated, are severely affected, and have been diagnosed with Edwards syndrome. The authors have employed FISH, using DNA probes from a chromosome 18-specific library, for the precise determination of the duplicated material in each of these patients. The clinical featuresmore » and the extent of the chromosomal duplication in these patients were compared with four previously reported partial trisomy 18 patients, to identify regions of chromosome 18 that may be responsible for certain clinical features of trisomy 18. The comparative analysis confirmed that there is no single region on 18q that is sufficient to produce the trisomy 18 phenotype and identified two regions on 18q that may work in conjunction to produce the Edwards syndrome phenotype. In addition, correlative analysis indicates that duplication of 18q12.3-q22.1 may be associated with more severe mental retardation in trisomy 18 individuals. 25 refs., 3 figs., 1 tab.« less

Investigating for the first time in Germany Diagnostic and Statistical Manual Fifth Edition (DSM-5) prevalences of adolescent full syndrome, Other Specified Feeding or Eating Disorder (OSFED), partial and subthreshold anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED). A national school-based cross-sectional survey with nine schools in Germany was undertaken that was aimed at students from grades 7 and 8. Of the 1775 students who were contacted to participate in the study, 1654 participated (participation rate: 93.2%). The sample consisted of 873 female and 781 male adolescents (mean age=13.4 years). Prevalence rates were established using direct symptom criteria with a structured inventory (SIAB-S) and an additional self-report questionnaire (Eating Disorder Inventory 2 (EDI-2)). Prevalences for full syndrome were 0.3% for AN, 0.4% for BN, 0.5% for BED and 3.6% for OSFED-atypical AN, 0% for BN (low frequency/limited duration), 0% for BED (low frequency/limited duration) and 1.9% for purging disorder (PD). Prevalences of partial syndrome were 10.9% for AN (7.1% established with cognitive symptoms only, excluding weight criteria), 0.2% for BN and 2.1% for BED, and of subthreshold syndrome were 0.8% for AN, 0.3% for BN and 0.2% for BED. Cases on EDI-2 scales were much more pronounced with 12.6-21.1% of the participants with significant sex differences. The findings were in accordance with corresponding international studies but were in contrast to other German studies showing much higher prevalence rates. The study provides, for the first time, estimates for DSM-5 prevalences of eating disorders in adolescents for Germany, and evidence in favour of using valid measures for improving prevalence estimates.

The Role of CHD7 Mutations in Patients with Idiopathic Hypogonadotropic Hypogonadism and Kallmann Syndrome

PubMed Central

Kim, Hyung-Goo; Layman, Lawrence C.

2013-01-01

Mutations in the chromodomain helicase DNA binding protein-7 (CHD7) cause CHARGE syndrome, which includes eye coloboma, heart malformations, atresia of the choanae, retardation of growth/development, genital anomalies, and ear abnormalities. CHARGE syndrome is usually sporadic, but is also autosomal dominant. CHD7 encodes a large protein that participates in chromatin remodeling and transcription. Findings from studies of mouse models employing ENU-mutagenesis or gene-trap methods recapitulate human CHARGE syndrome. CHARGE patients may manifest anosmia and/or hypogonadism, features that overlap with idiopathic hypogonadotropic hypogonadism (IHH) and Kallmann syndrome (KS). Similarly, IHH/KS patients may also display partial CHARGE features. Therefore, it has been hypothesized that IHH/KS represents a milder allelic variant of CHARGE syndrome, which has been supported by the identification of heterozygous CHD7 mutations in both normosmic IHH and KS. Developmental expression within the hypothalamus and the presence of human mutations indicate that CHD7 has an important role in puberty and reproduction. PMID:21856375

Wolf-Hirschhorn syndrome (WHS) and Patau syndrome are two of the most severe conditions resulting from chromosome abnormalities. WHS is caused by a deletion of 4p16, while Patau syndrome is caused by trisomy for some or all regions of chromosome 13. Though the etiologies of these syndromes differ, they share several features including pre- and postnatal growth retardation, microcephaly, cleft lip and palate, and cardiac anomalies. We present here a female fetus with deletion of 4p16 --> pter and duplication of 13q32 --> qter due to unbalanced segregation of t(4;13)(p16;q32) in the father. She displayed overlapping features of both of these syndromes on ultrasound. To the best of our knowledge, this is the first report of a fetus with both partial trisomy 13 and deletion of 4p16, the critical region for WHS. Copyright 2002 S. Karger AG, Basel

We report the case of a 38-year-old male with autosomal-dominant polycystic kidney disease (ADPKD) and concomitant nephrotic syndrome secondary to membranous nephropathy (MN). A 3-month course of prednisone 60 mg daily and losartan 100 mg daily resulted in resistance. Treatment with chlorambucil 0.2 mg/kg daily, low-dose prednisone, plus an angiotensin-converting enzyme inhibitor (ACEI) and an angiotensin II receptor blocker (ARB) for 6 weeks resulted in partial remission of his nephrotic syndrome for a duration of 10 months. After relapse of the nephrotic syndrome, a 13-month course of mycophenolate mofetil (MFM) 2 g daily and low-dose prednisone produced complete remission for 44 months. After a new relapse, a second 24-month course of MFM and low-dose prednisone produced partial to complete remission of proteinuria with preservation of renal function. Thirty-six months after MFM withdrawal, complete remission of nephrotic-range proteinuria was maintained and renal function was preserved. This case supports the idea that renal biopsy is needed for ADPKD patients with nephrotic-range proteinuria in order to exclude coexisting glomerular disease and for appropriate treatment/prevention of renal function deterioration. To the best of our knowledge, this is the first reported case of nephrotic syndrome due to MN in a patient with ADPKD treated with MFM, with remission of proteinuria and preservation of renal function after more than 10 years. Findings in this patient also suggest that MFM might reduce cystic cell proliferation and fibrosis, preventing progressive renal scarring with preservation of renal function. PMID:21552769

The water deprivation test (WDT) with direct or indirect measurement of plasma arginine vasopressin (AVP) is the method of choice for the differential diagnosis of the polydipsia-polyuria syndrome. In theory, direct measurement of AVP is highly attractive but is hampered by technical difficulties. The aim of the study was to evaluate the utility of copeptin, a surrogate of AVP secretion, in the diagnostic work-up of the polyuria-polydipsia syndrome and to compare its performance with the current diagnostic standard. In two tertiary referral centers, 20 healthy subjects and 50 patients with polydipsia-polyuria syndrome underwent WDT with measurements of both plasma AVP and copeptin levels. The reference diagnosis was based on clinical information and treatment response. Twenty-two patients (44%) were diagnosed with primary polydipsia, 17 (34%) with partial central diabetes insipidus (DI), nine (18%) with complete central DI, and two (4%) with nephrogenic DI. The indirect WDT led to a correct diagnosis in 35 of 50 patients (70%). The direct WDT with AVP or copeptin measurement correctly diagnosed 23 patients (46%) or 36 patients (72%), respectively. Baseline copeptin values greater than 20 pmol/liter identified patients with nephrogenic DI, and concentrations below 2.6 pmol/liter indicated complete central DI. The ratio between Δ copeptin (0800 to 1600 h) and serum sodium concentration at 1600 h yielded optimal diagnostic accuracy, allowing us to also discern partial central DI from primary polydipsia (sensitivity 86%, and specificity 100%). Copeptin holds promise as a diagnostic tool in the polyuria-polydipsia syndrome, improving significantly the diagnostic accuracy of the direct WDT.

To report the diagnosis and management of a patient with chronic ophthalmic topical anesthetic abuse and floppy eyelid syndrome. We describe the case of a 47-year-old man suffering from persistent bilateral ocular irritation and chronic corneal erosions. The patient was hospitalized in our ophthalmology department and underwent thorough ophthalmic, systemic, and psychiatric evaluation. Chronic topical anesthetic abuse was discovered. Removal of abused drops and copious lubricating treatment lead to partial improvement further permitting diagnosis of floppy eyelid syndrome. Definitive surgical treatment by horizontal eyelid tightening combined with continuous lubrication resulted in remission of symptoms. Uncommon conditions may coexist in 1 patient. In this case, floppy eyelid syndrome resulted in topical anesthetic abuse. Ophthalmologists should keep both these conditions in mind when treating patients with otherwise unexplained chronic persistent corneal erosions.

Lethal genes surviving by mosaicism: a possible explanation for sporadic birth defects involving the skin.

PubMed

Happle, R

1987-04-01

A genetic concept is advanced to explain the origin of several sporadic syndromes characterized by a mosaic distribution of skin defects. It is postulated that these disorders are due to the action of a lethal gene surviving by mosaicism. The presence of the mutation in the zygote will lead to death of the embryo at an early stage of development. Cells bearing the mutation can survive only in a mosaic state, in close proximity with normal cells. The mosaic may arise either from a gametic half chromatid mutation or from an early somatic mutation. This concept of origin is proposed to apply to the Schimmelpenning-Feuerstein-Mims syndrome, the McCune-Albright syndrome, the Klippel-Trenaunay syndrome, the Sturge-Weber syndrome, and neurocutaneous melanosis. Moreover, this etiologic hypothesis may apply to two other birth defects that have recently been delineated, the Proteus syndrome (partial gigantism of hands or feet, hemihypertrophy, macrocephaly, linear papillomatous epidermal nevus, subcutaneous hemangiomas and lipomas, accelerated growth, and visceral anomalies), and the Delleman-Oorthuys syndrome (orbital cyst, porencephaly, periorbital appendages, and focal aplasia of the skin.

SUMMARY Down syndrome (DS) results from full or partial trisomy of chromosome 21. However, the consequences of the underlying gene-dosage imbalance on adult tissues remain poorly understood. Here we show that in Ts65Dn mice, trisomic for 132 genes homologous to HSA21, triplication of Usp16 reduces self-renewal of hematopoietic stem cells and expansion of mammary epithelial cells, neural progenitors, and fibroblasts. Moreover, Usp16 is associated with decreased ubiquitination of Cdkn2a and accelerated senescence in Ts65Dn fibroblasts. Usp16 can remove ubiquitin from H2AK119, a critical mark for the maintenance of multiple somatic tissues. Downregulation of Usp16, either by mutation of a single normal USP16 allele or by shRNAs, largely rescues all these defects. Furthermore, in human tissues overexpression of USP16 reduces the expansion of normal fibroblasts and post-natal neural progenitors while downregulation of USP16 partially rescues the proliferation defects of DS fibroblasts. Taken together, these results suggest that USP16 plays an important role in antagonizing the self-renewal and/or senescence pathways in Down syndrome and could serve as an attractive target to ameliorate some of the associated pathologies.

Kennedy's disease, also known as bulbospinal muscular atrophy, is a rare, X-linked recessive neurodegenerative disorder affecting adult males. It is caused by expansion of an unstable cytosine-adenine-guanine tandem-repeat in exon 1 of the androgen-receptor gene on chromosome Xq11-12, and is characterized by spinal motor neuron progressive degeneration. Endocrinologically, these patients often have the features of hypogonadism associated to the androgen insensitivity syndrome, particularly its partial forms. We report 4 cases with the typical neurological presentation, consisting of slowly progressing generalized muscle weakness with atrophy and bulbar muscle involvement; these patients also had several endocrine manifestations; the most common non-neurological manifestation was gynecomastia. In all cases reported, molecular analysis showed an abnormal cytosine-adenine-guanine triplet repeat expansion in the androgen receptor gene. Copyright © 2014 SEEN.

We report a 12-year-old patient with Patau syndrome, in whom two cell lines were present from birth, one with total trisomy 13 due to isochromosome (13q), and one with partial trisomy 13. A cytogenetic re-evaluation at 9 years of age brought to light in skin fibroblasts a third cell line, partially monosomic for chromosome 13. The derivatives (13) present in the three cell lines were characterized through fluorescence in situ hybridization (FISH) experiments with suitable probes; the results suggested a sequence of rearrangements which beginning from an isochromosome (13q) could have led to the other two derivatives. We report the clinical data at birth and at the age of 12; at this age pigmentary lesions with phylloid pattern were noted. Cytogenetic findings of the chromosomal analyses on different tissues, including skin fibroblasts from differently pigmented areas, are also reported.

Obstructive sleep apnea (OSA) is a recurrent episode of partial or complete upper airway obstruction during sleep despite ongoing respiratory efforts and is implicated as the risk factor of cardiovascular disease. The OSA syndrome is typified by recurring partial or total occlusion of the pharynx, sleep fragmentation, episodes of gasping, and, eventually, daytime sleepiness. If it is left untreated, OSA syndrome can cause hypertension, coronary artery disease congestive heart disease, insulin resistance and death. In this review, we describe the pathogenesis and diagnosis of OSA. We also focused on the continuous positive airway pressure (CPAP) as the main therapy for OSA. CPAP has been shown to provide benefit for not only respiratory system, but also for cardiovascular system and metabolic system. Finally, we discussed briefly about the issue of adherence of using CPAP that could contribute to lower compliant in patient with OSA.

Griscelli syndrome is an infrequent disease first described in 1978. It is inherited in autosomal recessive form, and is distinguished by partial albinism, pigmentation dilution, cellular immunodeficiency, neurological involvement and uncontrolled phases of macrophage and lymphocyte activation. We report the case of a female child who started with ataxic gait when she was 23 months old. At physical examination a phenotype with brown skin and silvery gray hair, eyebrows and eyelashes was observed. Neurological evolution was with remissions and exacerbations, with cerebellar and, finally, bulbar compromise.

Variable penetrance of hypogonadism in a sibship with Kallmann syndrome due to a deletion of the KAL gene

Parenti, G.; Rizzolo, M.G.; Ghezzi, M.

We report on the clinical and molecular characterization of 3 sibs with X-linked ichthyosis and variable expression of Kallmann syndrome. One of the affected brothers had mild hyposmia and showed normal pubertal progression. However, we demonstrated the same partial deletion of the X-linked Kallmann gene, sparing the first exon in the mildly affected patient as well as in one of his severely affected brothers. 13 refs., 1 fig., 1 tab.

Abnormal serum IgG subclass pattern in children with Down's syndrome.

Susceptibility to infections is a well known feature of Down's syndrome. The possible relation between this predisposition and the serum concentrations of the IgG subclasses was studied in 38 children with Down's syndrome aged 1-12 years. An age matched group of 50 healthy children served as controls. The serum concentrations of IgG1 and IgG3 were significantly raised among children with Down's syndrome in all three age groups studied (that is 1-2.5, 4-8, and 9-12 years). The serum concentrations of IgG2 were normal in the first two groups but significantly reduced in the third age group. In contrast, the concentrations of IgG4 among children with Down's syndrome were significantly reduced in all three age groups. Moreover, among the children with Down's syndrome aged 4-12 years 68% (15/22) had IgG4 concentrations below 2 SDs of the geometrical mean of the controls. The results may partially explain the proneness of children with Down's syndrome to infections with encapsulated bacteria. Although the underlying cause of these abnormalities is unknown, IgG subclass determination seems relevant in the clinical evaluation of children with Down's syndrome.

The dose response relationship for the acute gastrointestinal syndrome following total-body irradiation prevents analysis of the full recovery and damage to the gastrointestinal system, since all animals succumb to the subsequent 100% lethal hematopoietic syndrome. A partial-body irradiation model with 5% bone marrow sparing was established to investigate the prolonged effects of high-dose radiation on the gastrointestinal system, as well as the concomitant hematopoietic syndrome and other multi-organ injury including the lung. Herein, cellular and clinical parameters link acute and delayed coincident sequelae to radiation dose and time course post-exposure. Male rhesus Macaca mulatta were exposed to partial-body irradiation with 5% bone marrow (tibiae, ankles, feet) sparing using 6 MV linear accelerator photons at a dose rate of 0.80 Gy min(-1) to midline tissue (thorax) doses in the exposure range of 9.0 to 12.5 Gy. Following irradiation, all animals were monitored for multiple organ-specific parameters for 180 d. Animals were administered medical management including administration of intravenous fluids, antiemetics, prophylactic antibiotics, blood transfusions, antidiarrheals, supplemental nutrition, and analgesics. The primary endpoint was survival at 15, 60, or 180 d post-exposure. Secondary endpoints included evaluation of dehydration, diarrhea, hematologic parameters, respiratory distress, histology of small and large intestine, lung radiographs, and mean survival time of decedents. Dose- and time-dependent mortality defined several organ-specific sequelae, with LD50/15 of 11.95 Gy, LD50/60 of 11.01 Gy, and LD50/180 of 9.73 Gy for respective acute gastrointestinal, combined hematopoietic and gastrointestinal, and multi-organ delayed injury to include the lung. This model allows analysis of concomitant multi-organ sequelae, thus providing a link between acute and delayed radiation effects. Specific and multi-organ medical countermeasures can be assessed for efficacy and interaction during the concomitant evolution of acute and delayed key organ-specific subsyndromes.

Partial pleural covering for intractable pneumothorax in patients with Birt-Hogg-Dubé Syndrome.

2017-03-01

Birt-Hogg-Dubé syndrome (BHD) is an inherited disorder associated with a germline mutation of the folliculin (FLCN) gene. Most patients with BHD have multiple pulmonary cysts, and are at high risk of repeated pneumothorax. Although an increasing number of patients are diagnosed with BHD by genetic testing, therapeutic approaches for intractable pneumothorax have not yet been described. We treated three patients who had repeated episodes of pneumothorax. All had multiple pulmonary cysts in the lower lobes, and two had a family history of pneumothorax. Video-assisted thoracic surgery was used to perform wedge resections and partial pleural covering of the cystic lesions. The partial pleural covering technique used sheets of polyglycolic acid felt or regenerative oxidized cellulose mesh. The resected tissues underwent histopathological evaluation, and peripheral blood leukocytes were tested for FLCN mutations. The operative times were less than 2 h, and there were no complications. The resected cysts had histopathological features characteristic of BHD lung. All patients were found to have FLCN germline mutations; thus their repeated pneumothoraces were a manifestation of BHD. None of the patients developed respiratory problems after undergoing the partial pleural covering procedure, and they have all been well without pneumothorax for 30 months or more. Partial pleural covering combined with resection of protruding cysts should be a safe and effective therapeutic approach for BHD patients with intractable pneumothorax. Further investigation is needed to establish a detailed protocol for treatment of pneumothorax that results in minimal functional impairment. © 2015 John Wiley & Sons Ltd.

To evaluate the efficacy and tolerability of intravenous (IV) levetiracetam in refractory status epilepticus of migrating partial seizures in infancy (MPSI). IV levetiracetam was infused in two infants, first as a loading dose of 60mg/kg in 30min, then at 30mg/kg twice a day. Both infants were continuously monitored with video-EEG before, during and after the drug trial. Blood count, liver enzymes, serum creatinine, ammonia and lactate blood levels were performed repeatedly before and after the IV levetiracetam administration. Follow-up was of 16 and 10 months. EEG monitoring allowed the diagnosis of MPSI, showing the typical seizures pattern in both patients. IV levetiracetam was effective in stopping status epilepticus in both infants. Levetiracetam also prevented the recurrence of status epilepticus during follow-up. No adverse reactions were observed during the infusion phase or during follow-up. MPSI is a newly recognized epileptic syndrome characterized by early onset of intractable partial seizures arisingly independently and sequentially from both hemispheres, migrating from one region of the brain to another and from one hemisphere to another. We report the efficacy of intravenous levetiracetam in resolving refractory status epilepticus in two infants with this new epilepsy syndrome.

Mutations in the PIGN gene involved in the glycosylphoshatidylinositol (GPI) anchor biosynthesis pathway cause Multiple Congenital Anomalies–Hypotonia–Seizures syndrome 1 (MCAHS1). The syndrome manifests developmental delay, hypotonia, and epilepsy, combined with multiple congenital anomalies. We report on the identification of a homozygous novel c.755A>T (p.D252V) deleterious mutation in a patient with Israeli–Arab origin with MCAHS1. The mutated PIGN caused a significant decrease of the overall GPI-anchored proteins and CD24 expression. Our results, strongly support previously published data, that partial depletion of GPI-anchored proteins is sufficient to cause severe phenotypic expression. PMID:26364997

Ectodermal dysplasias (EDs) are a group of genodermatoses characterized by malformations of tissues derived from the ectoderm, including the skin, its appendages (hair, nails, sweat glands), teeth, and the breasts. Ectodermal dysplasia syndactyly syndrome (EDSS) is a rare, newly described type of ED involving syndactyly. We report 2 Yemeni siblings with typical EDSS manifestations, including bilateral, partial cutaneous syndactyly of the fingers and toes; sparse, coarse, brittle scalp hair, eyebrows, and eyelashes; and conical, widely spaced teeth with enamel notches. In addition, the siblings presented with other features hitherto not described for this syndrome, such as adermatoglyphia, onychogryphosis, hypoplastic widely spaced nipples, hypoplastic thumbs, and red scalp hair.

Turner syndrome (TS) is a gonadal dysgenesis related to partial or total lack of one of the X chromosomes. It this report we describe a young patient presenting some somatic features of TS, who underwent spontaneous puberty and was eumenoorheic up to the age of 23. Using fluorescent in situ hybridization (FISH) mosaic karyotype (45X[131]/47XXX[9]) of TS and triple X syndrome was found. She presented uncommon for TS somatic hemihypotrophy and underwent growth hormone and surgical therapy. The patient was diagnosed with premature ovarian failure when she was 23, with absent follicular reserve. Clinical features of this case and a few published cases will be reviewed briefly.

Poland's syndrome is a rare congenital anomaly consisting of unilateral partial or total absence of a breast and/or pectoralis major muscle, and ipsilateral symbrachydactyly. Many structural and functional abnormalities have been described in association with the syndrome. However, only a few hemostatic disorders have been reported. The case of a 12-year-old secondary school girl with unilateral hypoplasia of the breast, absence of anterior axillary fold and absence of the pectoralis major muscle is hereby presented. She also had thrombocytopenia and several episodes of spontaneous bleeding from the ipsilateral anterior chest wall. She did well on medical treatment, with no recurrence of bleeding 10 months after treatment. The author is not aware of any previously reported case of Poland's syndrome associated with bleeding disorder in Africa. This case is presented to alert clinicians of its existence and possible association with hematological disorders.

Cardiovascular risk in Turner syndrome.

Donato, Beatriz; Ferreira, Maria João

2018-06-01

Turner syndrome is a relatively common genetic disorder of female development, characterized by partial or complete absence of an X chromosome, with a variable clinical presentation. Congenital or acquired cardiovascular disease is highly prevalent and a major cause of early death in this syndrome. The most feared complication is aortic dissection, which can occur at a very young age and requires careful assessment of its risk factors. A systematic literature search identified sixty relevant publications. These were reviewed with regard to the increased risk of cardiovascular disease in women with Turner syndrome, especially in pregnancy. The most common congenital cardiovascular defects are presented and illustrated with appropriate iconography. The current recommendations regarding the screening and monitoring of cardiovascular disease in these patients are discussed. Copyright © 2018 Sociedade Portuguesa de Cardiologia.

Turner syndrome, characterized by the presence of a monosomy X cell line, is a common chromosomal disorder. Patients with Turner syndrome are usually phenotypically female, and male cases are rarely reported. Here, we report a fetus with a mosaic karyotype: mos 45,X/46,X,del(Y)(q11.21). The fetus was initially misdiagnosed as female with Turner syndrome by both noninvasive prenatal testing and cytogenetic analysis of amniotic fluid and was subsequently found to have male anatomy by antenatal ultrasonography at 24 weeks gestational age. Through single nucleotide polymorphism-array and fluorescence in situ hybridization testing, we found that there was a truncated Y chromosome with sex-determining region Y (SRY) present in some cells of the fetus, which caused the male features in the fetus. © 2018 Japan Society of Obstetrics and Gynecology.

Diagnosis and treatment of movement system impairment syndromes.

PubMed

Sahrmann, Shirley; Azevedo, Daniel C; Dillen, Linda Van

Diagnoses and treatments based on movement system impairment syndromes were developed to guide physical therapy treatment. This masterclass aims to describe the concepts on that are the basis of the syndromes and treatment and to provide the current research on movement system impairment syndromes. The conceptual basis of the movement system impairment syndromes is that sustained alignment in a non-ideal position and repeated movements in a specific direction are thought to be associated with several musculoskeletal conditions. Classification into movement system impairment syndromes and treatment has been described for all body regions. The classification involves interpreting data from standardized tests of alignments and movements. Treatment is based on correcting the impaired alignment and movement patterns as well as correcting the tissue adaptations associated with the impaired alignment and movement patterns. The reliability and validity of movement system impairment syndromes have been partially tested. Although several case reports involving treatment using the movement system impairment syndromes concept have been published, efficacy of treatment based on movement system impairment syndromes has not been tested in randomized controlled trials, except in people with chronic low back pain.

There is limited research on clinical features related to age of presentation of the Attenuated Psychosis Syndrome in children and adolescents (CAD). Based on findings in CAD with psychosis, we hypothesized that an older age at presentation of Attenuated Psychosis Syndrome would be associated with less severe symptoms and better psychosocial functioning than presentation in childhood or younger adolescence. Ninety-four CAD (age 9-18) meeting Attenuated Psychosis Syndrome criteria participated in the study. The sample was divided and compared according to the age of presentation of Attenuated Psychosis Syndrome (9-14 vs 15-18 years). The predictive value of age of Attenuated Psychosis Syndrome presentation was investigated using receiver operating characteristic (ROC)-curve calculations. The two Attenuated Psychosis Syndrome groups were homogeneous in terms of gender distribution, IQ scores and comorbid diagnoses. Older Attenuated Psychosis Syndrome patients showed better functioning and lower depressive scores. ROC curves revealed that severity of functional impairment was best predicted using an age of presentation cut-off of 14.9 years for social functioning and 15.9 years for role functioning. This study partially confirmed our hypothesis; older age at presentation of Attenuated Psychosis Syndrome was associated with less functional impairment, but age was not associated with psychotic symptoms.

Children with chromosome 22q11.2 Deletion Syndrome (22q11.2DS), Fragile X Syndrome (FXS), or Turner Syndrome (TS) are considered to belong to distinct genetic groups, as each disorder is caused by separate genetic alterations. Even so, they have similar cognitive and behavioral dysfunctions, particularly in visuospatial and numerical abilities. To assess evidence for common underlying neural microstructural alterations, we set out to determine whether these groups have partially overlapping white matter abnormalities, relative to typically developing controls. We scanned 101 female children between 7 and 14 years old: 25 with 22q11.2DS, 18 with FXS, 17 with TS, and 41 aged-matched controls using diffusion tensor imaging (DTI). Anisotropy and diffusivity measures were calculated and all brain scans were nonlinearly aligned to population and site-specific templates. We performed voxel-based statistical comparisons of the DTI-derived metrics between each disease group and the controls, while adjusting for age. Girls with 22q11.2DS showed lower fractional anisotropy (FA) than controls in the association fibers of the superior and inferior longitudinal fasciculi, the splenium of the corpus callosum, and the corticospinal tract. FA was abnormally lower in girls with FXS in the posterior limbs of the internal capsule, posterior thalami, and precentral gyrus. Girls with TS had lower FA in the inferior longitudinal fasciculus, right internal capsule and left cerebellar peduncle. Partially overlapping neurodevelopmental anomalies were detected in all three neurogenetic disorders. Altered white matter integrity in the superior and inferior longitudinal fasciculi and thalamic to frontal tracts may contribute to the behavioral characteristics of all of these disorders.

Previous research in South Africa revealed very high rates of fetal alcohol syndrome (FAS), of 46-89 per 1000 among young children. Maternal and child data from studies in this community summarize the multiple predictors of FAS and partial fetal alcohol syndrome (PFAS). Sequential regression was employed to examine influences on child physical characteristics and dysmorphology from four categories of maternal traits: physical, demographic, childbearing, and drinking. Then, a structural equation model (SEM) was constructed to predict influences on child physical characteristics. Individual sequential regressions revealed that maternal drinking measures were the most powerful predictors of a child's physical anomalies (R² = .30, p < .001), followed by maternal demographics (R² = .24, p < .001), maternal physical characteristics (R²=.15, p < .001), and childbearing variables (R² = .06, p < .001). The SEM utilized both individual variables and the four composite categories of maternal traits to predict a set of child physical characteristics, including a total dysmorphology score. As predicted, drinking behavior is a relatively strong predictor of child physical characteristics (β = 0.61, p < .001), even when all other maternal risk variables are included; higher levels of drinking predict child physical anomalies. Overall, the SEM model explains 62% of the variance in child physical anomalies. As expected, drinking variables explain the most variance. But this highly controlled estimation of multiple effects also reveals a significant contribution played by maternal demographics and, to a lesser degree, maternal physical and childbearing variables.

2017-01-24

Patients with Down syndrome can present with a variety of oral manifestations such as hypodontia, periodontal disease, premature tooth loss, reduced salivary flow, crowding of teeth in both arches, and decreased occlusal vertical dimension. The intellectual ability of people with Down syndrome varies widely. They present with a mild-to-moderate intellectual disability that restricts their ability to communicate and adjust to their environment, which can add complexity in the overall dental treatment. There is little information in the literature regarding the prosthodontic rehabilitation for patients with Down syndrome in combination with dental implant placement. An implant-assisted removable partial dental prosthesis can be a cost-effective treatment alternative for carefully chosen patients with Down syndrome. This article presents the treatment of a 44-year-old male patient with Down syndrome and a moderate intellectual disability who presented with congenital and acquired tooth loss with significant occlusal discrepancies. The treatment included a prosthodontic approach that used a single dental implant, which will be described and illustrated in this article. © 2017 by the American College of Prosthodontists.

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

Lack of Spartin Protein in Troyer Syndrome

2017-01-01

Background Hereditary spastic paraplegias (SPG1-SPG33) are characterized by progressive spastic weakness of the lower limbs. A nucleotide deletion (1110delA) in the (SPG20; OMIM 275900) spartin gene is the origin of autosomal recessive Troyer syndrome. This mutation is predicted to cause premature termination of the spartin protein. However, it remains unknown whether this truncated spartin protein is absent or is present and partially functional in patients. Objective To determine whether the truncated spartin protein is present or absent in cells derived from patients with Troyer syndrome. Design Case report. Setting Academic research. Patients We describe a new family with Troyer syndrome due to the 1110delA mutation. Main Outcome Measures We cultured primary fibroblasts and generated lymphoblasts from affected individuals, carriers, and control subjects and subjected these cells to immunoblot analyses. Results Spartin protein is undetectable in several cell lines derived from patients with Troyer syndrome. Conclusions Our data suggest that Troyer syndrome results from complete loss of spartin protein rather than from the predicted partly functional fragment. This may reflect increased protein degradation or impaired translation. PMID:18413476

The Architecture of the Pollen Hoarding Syndrome in Honey Bees: Implications for Understanding Social Evolution, Behavioral Syndromes, and Selective Breeding

PubMed Central

Rueppell, Olav

2014-01-01

Social evolution has influenced every aspect of contemporary honey bee biology, but the details are difficult to reconstruct. The reproductive ground plan hypothesis of social evolution proposes that central regulators of the gonotropic cycle of solitary insects have been coopted to coordinate social complexity in honey bees, such as the division of labor among workers. The predicted trait associations between reproductive physiology and social behavior have been identified in the context of the pollen hoarding syndrome, a larger suite of interrelated traits. The genetic architecture of this syndrome is characterized by a partially overlapping genetic architecture with several consistent, pleiotropic QTL. Despite these central QTL and an integrated hormonal regulation, separate aspects of the pollen hoarding syndrome may evolve independently due to peripheral QTL and additionally segregating genetic variance. The characterization of the pollen hoarding syndrome has also demonstrated that this syndrome involves many non-behavioral traits, which may be the case for numerous “behavioral” syndromes. Furthermore, the genetic architecture of the pollen hoarding syndrome has implications for breeding programs for improving honey health and other desirable traits: If these traits are comparable to the pollen hoarding syndrome, consistent pleiotropic QTL will enable marker assisted selection, while sufficient additional genetic variation may permit the dissociation of trade-offs for efficient multiple trait selection.

In Germany Puumala virus (PUUV), known to cause mild forms of hemorrhagic fever with renal syndrome (HFRS), is the predominating endemic hantavirus. We herein describe an unusually severe case of a PUUV infection that occurred in summer 2015 in South Eastern Germany in a region known to be endemic for PUUV since over ten years. A 54-year-old female gardener was admitted to hospital with fever, cough and dyspnea. Within 48hours the patient developed a rapid progressive adult respiratory distress syndrome (ARDS) with circulatory failure and required ECMO (extracorporeal membrane oxygenation) treatment. Serological and molecular biological examinations of serum samples confirmed an infection with PUUV. Partial sequences of the S- and M-segment clustered to a strain previously described in South Eastern Germany. Our reported case highlights, that in rare incidents PUUV can cause hantavirus cardiopulmonary syndrome, a syndrome that is usually found after infections with New World hantaviruses, and neurological symptoms.

Seckel's syndrome is a rare form of primordial dwarfism, characterized by peculiar facial appearance. In the past, this condition was overdiagnosed, and most attention was given to the facial and skeletal features to define more precise diagnostic criteria. The presence of mental retardation and neurologic signs is one of the peculiar features of this syndrome, but only recently were rare cases of malformation of cortical development described, as documented by magnetic resonance imaging (MRI). Here, we present three new cases of Seckel's syndrome showing different malformations of cortical development (one gyral hypoplasia, one macrogyria and partial corpus callosum agenesis, and one bilateral opercular macrogyria). We hypothesize that the different types of clinical expression of our patients could be explained by different malformation of cortical development types. We think that MRI studies could be performed in malformative syndromes because of the possible correlations between type and extent of the lesion and the clinical picture of any individual case.

Ischemic Stroke and Epilepsy in a Patient with Tourette´s Syndrome: Association with the Antiphospholipid Syndrome and Good Response to Levetiracetam

2008-01-01

The role played by different humoral factors, including antiphospholipid antibodies, in the pathogenesis of Tourette syndrome (TS) is still presently unclear. We present a patient with chronic and severe TS who, at the age of 16 years, presented an ischemic stroke in the left posterior cerebral artery and/or postero-inferior temporal branch of the left medial cerebral artery. A complete study was negative with the exception of a positive lupus anticoagulant. The stroke was related with the primary antiphospholipid syndrome (APS). The stroke manifested visual abnormalities and thereafter by secondary generalized complex partial seizures. The epileptic syndrome was initially difficult to control but responded dramatically to levetiracetam. With this therapy, the manifestations of TS, especially the tics, improved. We conclude that some TS cases may present APS. In addition, levetiracetam may be useful in the management of TS. Further investigations should pursue both these facts. PMID:19018305

We report the case of a patient with metastatic renal cell carcinoma with Xp11.2 translocation/transcription factor E3 (TFE3) gene fusion who had presented with sunitinib-induced nephrotic syndrome in association with favorable and durable treatment response. The nephrotic syndrome was managed successfully by discontinuing sunitinib and symptomatic treatment. The 27-year-old female patient presenting with right upper abdominal pain was diagnosed with Xp11.2 translocation renal cell carcinoma on the right side with multiple pulmonary and hepatic metastases. She underwent radical nephrectomy and took a daily dose of 37.5 mg sunitinib. Partial response to sunitinib was achieved and maintained for 5 months, but when nephrotic syndrome occurred, drug intake was discontinued. The nephrotic syndrome gradually resolved around 2 months after discontinuation of sunitinib and medical management. Our case highlighted the favorable response of a particular non-clear cell type renal cell carcinoma to sunitinib and the specific toxicity associated with the antiangiogenic effect of sunitinib.

Blood heat and hemorrhage (BHH) syndrome is the most common bleeding disease in clinic. In this study, a rat model with BHH syndrome was built for the first time. Biochemical study showed the intrinsic coagulation pathways and the platelet aggregation rate in the rat model were inhibited, while extrinsic pathway of coagulation cascade was activated. An UHPLC/Q-TOF MS combined with orthogonal partial least squares-discriminant analysis (OPLS-DA) was employed to construct plasma metabolic profiling of the rat model with BHH syndrome. Twenty-four unique metabolites were identified, which were involved in glycerophospholipid metabolism, arachidonic acid metabolism, fatty acid metabolism, amino acid metabolism and cholic acid metabolism. In the end, we concluded that bleeding mechanism of the rat with BHH syndrome may be associated with augmenting blood viscosity, inhibiting platelet aggregation and intrinsic coagulation pathways.

Turner Syndrome was diagnosed in a 45 years old female, known case of Acute Myeloid Leukaemia (AML) with maturation, on Bone Marrow biopsy. She presented with blurred vision, vertigo, exertional dyspnoea and insomnia. She did not show the typical features of Turner syndrome, but her cytogenetis confirmed the diagnosis. Bone marrow biopsy showed diffuse infiltration of blast cells with cellularity around 80-85% and haematopoietic suppression. Karyotype analysis showed: 45 X, -X, t (8; 21) (q22; q22) [According to The International System for Human Cytogenetic Nomenclature (ISCN)]. Turner syndrome is caused by partial or complete absence of second X chromosome in a female. It is known to have Cardiovascular and Reproductive complications but it is rare to find haematologic malignancies. There are few similar reported cases of AML associated with Turner syndrome, therefore this is a unique case presented to Jinnah Postgraduate Medical Center, Karachi, Pakistan and further research should be done to identify more similar cases to explore the prognostic significance of this association.

Partially wrong? Partial equilibrium and the economic analysis of public health emergencies of international concern.

PubMed

2008-11-01

We argue that traditional health economic analysis is ill-equipped to estimate the cost effectiveness and cost benefit of interventions that aim at controlling and/or preventing public health emergencies of international concern (such as pandemic influenza or severe acute respiratory syndrome). The implicit assumption of partial equilibrium within both the health sector itself and--if a wider perspective is adopted--the economy as a whole would be violated by such emergencies. We propose an alternative, with the specific aim of accounting for the behavioural changes and capacity problems that are expected to occur when such an outbreak strikes.

Androgen insensitivity syndrome (AIS) is the most frequent etiology of 46,XY disorders of sex development (DSDs), and it is an X-linked disorder caused by mutations in the androgen receptor (AR) gene. AIS patients present a broad phenotypic spectrum and individuals with a partial phenotype present with different degrees of undervirilized external genitalia. There are more than 500 different AR gene allelic variants reported to be linked to AIS, but the presence of somatic mosaicisms has been rarely identified. In the presence of a wild-type AR gene, a significant degree of spontaneous virilization at puberty can be observed, and it could influence the gender assignment, genetic counseling and the clinical and psychological management of these patients and the psychosexual outcomes of these patients are not known. In this study, we report two patients with AR allelic variants in heterozygous (c.382G>T and c.1769-1G>C) causing a partial AIS (PAIS) phenotype. The first patient was raised as female and she had undergone a gonadectomy at puberty. In both patients there was congruency between gender of rearing and gender identity and gender role. Somatic mosaicism is rare in AIS and nonsense AR variant allelic can cause partial AIS phenotype in this situation. Despite the risk of virilization and prenatal androgen exposure, the gender identity and gender role was concordant with sex of rearing in both cases. A better testosterone response can be expected in male individuals and this should be considered in the clinical management.

Alpha thalassemia-mental retardation, X-linked (ATR-X) syndrome is a rare genetic disorder with a variety of clinical manifestations. Gastrointestinal symptoms described in this syndrome include difficulties in feeding, regurgitation and vomiting which may lead to aspiration pneumonia, abdominal pain, distention, and constipation. We present a 19-year-old male diagnosed with ATR-X syndrome, who suffered from recurrent colonic volvulus that ultimately led to bowel necrosis with severe septic shock requiring emergent surgical intervention. During 1 year, the patient was readmitted four times due to poor oral intake, dehydration and abdominal distention. Investigation revealed partial small bowel volvulus which resolved with non-operative treatment. Small and large bowel volvulus are uncommon and life-threatening gastrointestinal manifestations of ATR-X patients, which may contribute to the common phenomenon of prolonged food refusal in these patients. © 2015 Wiley Periodicals, Inc.

Poland's syndrome: report of a variant.

PubMed Central

Legbo, Jacob Ndas

2006-01-01

Poland's syndrome is a rare congenital anomaly consisting of unilateral partial or total absence of a breast and/or pectoralis major muscle, and ipsilateral symbrachydactyly. Many structural and functional abnormalities have been described in association with the syndrome. However, only a few hemostatic disorders have been reported. The case of a 12-year-old secondary school girl with unilateral hypoplasia of the breast, absence of anterior axillary fold and absence of the pectoralis major muscle is hereby presented. She also had thrombocytopenia and several episodes of spontaneous bleeding from the ipsilateral anterior chest wall. She did well on medical treatment, with no recurrence of bleeding 10 months after treatment. The author is not aware of any previously reported case of Poland's syndrome associated with bleeding disorder in Africa. This case is presented to alert clinicians of its existence and possible association with hematological disorders. Images Figure 1 PMID:16532987

Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are well-recognized examples of imprinting in humans. They occur most commonly with paternal and maternal 15q11-13 deletions, but also with maternal and paternal disomy. Both syndromes have also occurred more rarely in association with smaller deletions seemingly causing abnormal imprinting. A putative mouse model of PWS, occurring with maternal duplication (partial maternal disomy) for the homologous region, has been described in a previous paper but, although a second imprinting effect that could have provided a mouse model of AS was found, it appeared to be associated with a slightly different region of the chromosome. Here, we provide evidence that the same region is in fact involved and further demonstrate that animals with paternal duplication for the region exhibit characteristics of AS patients. A mouse model of AS is, therefore, strongly indicated.

Wernicke-Korsakoff syndrome (WKS) and disordered eating behavior have been reported separately after bariatric surgery. We report a patient who following a bariatric operation developed WKS associated with a disturbed eating behavior without vomiting. This morbidly obese man developed an intense fear of gaining weight in the postoperative period and engaged in an extreme form of "food avoidance behavior". 2 months postoperatively after severe weight loss, he was hospitalized with disorientation and an amnesic syndrome. He was discharged 2 months later with stable weight and regular eating habits. Despite this, at the last follow-up visit 2 years postoperatively, he still had a residual partial amnesic syndrome. The surgical team must be aware of peculiar forms of pathological eating that may appear after bariatric surgery; the emergence of an eating avoidance disorder may be associated with the development of WKS.

The femoral hypoplasia-unusual facies syndrome (FFS) is a very rare association of femoral and facial abnormalities. Maternal diabetes mellitus has been mainly involved as the causal agent. We report the second case of FFS with anomalies in the central nervous system (CNS) including corticosubcortical atrophy, colpocephaly, partial agenesis of corpus callosum, hypoplasia of the falx cerebri and absent septum pellucidum. The psychomotor development has been normal. We propose that the CNS defects observed in these patients are part of the spectrum of abnormalities in the FFS.

A congenital disorder with variable manifestations, including partial gigantism of the hands and feet with hypertrophy of soles, nevi, hemihypertrophy, gynecomastia, macrocephaly and other skull abnormalities, and abdominal lipomatosis. The cause is unknown, although a genetic origin, generally of autosomal-dominant transmission, has been conjectured. Symptoms can be treated, but there is no known cure. We present the case of a young male with grotesque overgrowth of the right lower limb, splenomegaly and multiple nevi. Angiography revealed venous malformation within the limb. The findings are in conformity to the criteria for the Proteus syndrome.

Severe acute respiratory syndrome is a new disease that is highly contagious and is spreading in the local community and worldwide. This report is of a hospital medical officer with severe acute respiratory syndrome. He presented with sudden onset of fever, chills, myalgia, headache, and dizziness in early March 2003. He developed progressive respiratory symptoms and bilateral pulmonary infiltrates during the second week of his illness. Blood tests showed lymphopenia, mild thrombocytopenia, and prolonged activated partial thromboplastin time with normal d-dimer level. His chest condition gradually responded to ribavirin and corticosteroids, and serial chest X-ray showed resolving pulmonary infiltrates. The importance of early diagnosis lies in the potential for early treatment, leading to better response.

Sheehan's syndrome, first described in 1937, is characterised by postpartum haemorrhage, pituitary necrosis, lactational failure and hypopitutarism. Presentation is variable and late presentations are not unusual due to partial ischaemic injury of the pituitary and gradual loss of endocrine function. A history of postpartum haemorrhage is usual but in some cases it is not elicited. Presentations such as malaise, fatigue, hypoglycaemia, decline in cognition, hyponatraemia, pancytopoenia, osteoporosis, secondary infertility, confusion and coma have all been reported. Two interesting cases of Sheehan's syndrome are presented that were diagnosed in the eighth decade; one due to atypical presentation of recurrent hyponatraemia and confusion, another from hypoglycaemic coma and symptoms of malaise and lethargy.

4p- syndrome and 9p tetrasomy mosaicism with cleft lip and palate.

Chromosome 4p- syndrome is a multiple malformation syndrome associated with partial deletion of the short arm of chromosome 4 (4p-). It is characterized by dysmorphic features and retarded development. Cleft lip and/or palate are the major clinical manifestations. Cases of tetrasomy 9p are extremely rare; the principal clinical manifestations of this condition are characteristic craniofacial abnormalities, generalized hypotonia and severe mental retardation. We present the first case of a female infant with 4p deletion and tetrasomy 9p mosaicism, exhibiting a left-sided cleft lip, alveolus and soft palate. Karyotype analysis of lymphocytes cultured from the patient revealed that she was mosaic: 86% of the cells were 46, XX, add (4) (p15.32) and 14% were 47, XX, add (4) (p15.32), +idic (9)(q12). The G-banding pattern appeared consistent with either translocation or partial proximal deletion of 4p. In order to make a definitive cytogenetic diagnosis of isodicentric chromosome 9, fluorescence in situ hybridization (FISH) was applied. At 8 months, when the patient weighed 4.3 kg, her cleft lip was repaired. Before and after surgery there were no seizures, and the postoperative course was uneventful.

Preterm delivery is often performed by Caesarean section. We investigated modes of anaesthesia and risk factors for general anaesthesia among women undergoing preterm Caesarean delivery. Women undergoing Caesarean delivery between 24(+0) and 36(+6) weeks' gestation were identified from a multicentre US registry. The mode of anaesthesia was classified as neuraxial anaesthesia (spinal, epidural, or combined spinal and epidural) or general anaesthesia. Logistic regression was used to identify patient characteristic, obstetric, and peripartum risk factors associated with general anaesthesia. Within the study cohort, 11 539 women had preterm Caesarean delivery; 9510 (82.4%) underwent neuraxial anaesthesia and 2029 (17.6%) general anaesthesia. In our multivariate model, African-American race [adjusted odds ratio (aOR)=1.9; 95% confidence interval (CI)=1.7-2.2], Hispanic ethnicity (aOR=1.5; 95% CI=1.2-1.8), other race (aOR=1.4; 95% CI=1.1-1.9), and haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome or eclampsia (aOR=2.8; 95% CI=2.2-3.5) were independently associated with receiving general anaesthesia for preterm Caesarean delivery. Women with an emergency Caesarean delivery indication had the highest odds for general anaesthesia (aOR=3.5; 95% CI=3.1-3.9). For every 1 week decrease in gestational age at delivery, the adjusted odds of general anaesthesia increased by 13%. In our study cohort, nearly one in five women received general anaesthesia for preterm Caesarean delivery. Although potential confounding by unmeasured factors cannot be excluded, our findings suggest that early gestational age at delivery, emergent Caesarean delivery indications, hypertensive disease, and non-Caucasian race or ethnicity are associated with general anaesthesia for preterm Caesarean delivery. © The Author 2015.

To assess whether the high soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) ratio is associated with adverse outcomes (e.g., HELLP syndrome [hemolysis, elevated liver enzymes, and low platelets], severe hypertension uncontrolled by medication, non-reassuring fetal status, placental abruption, pulmonary edema, growth arrest, maternal death, or fetal death) and a shorter duration to delivery in early-onset fetal growth restriction (FGR). Thirty-four women with FGR diagnosed at <34.0 weeks were recruited. Serum angiogenic marker levels were estimated within 6 hours of a diagnosis of FGR. A receiver operating characteristic curve was used to determine the threshold of the sFlt-1/PlGF ratio to predict adverse outcomes. We used multivariable logistic regression analysis to examine the association between the sFlt-1/PlGF ratio and adverse outcomes. Finally, we used Kaplan-Meier analysis and the log-rank test to assess the probability of delay in delivery. Women who developed adverse outcomes within a week had a significantly higher sFlt-1/PlGF ratio than did those who did not develop complications. A cutoff value of 86.2 for the sFlt-1/PlGF ratio predicted adverse outcomes, with a sensitivity and specificity of 77.8% and 80.0%, respectively. Moreover, 58.4% of women with an sFlt-1/PlGF ratio ≥86.2 versus 9.1% of those with an sFlt-1/PlGF ratio <86.2 delivered within a week of presentation (p < 0.001). In multivariate analyses, an sFlt-1/PlGF ratio ≥86.2 (adjusted odds ratio 9.52; 95% confidence interval, 1.25-72.8) was associated with adverse maternal and neonatal outcomes. A high sFlt-1/PlGF ratio was associated with adverse outcomes and a shorter duration to delivery in early-onset FGR.

Activated phosphoinositide 3-kinase (PI3K) δ Syndrome (APDS), caused by autosomal dominant mutations in PIK3CD (APDS1) or PIK3R1 (APDS2), is a heterogeneous primary immunodeficiency. While initial cohort-descriptions summarized the spectrum of clinical and immunological manifestations, questions about long-term disease evolution and response to therapy remain. The prospective European Society for Immunodeficiencies (ESID)-APDS registry aims to characterize the disease course, identify outcome predictors, and evaluate treatment responses. So far, 77 patients have been recruited (51 APDS1, 26 APDS2). Analysis of disease evolution in the first 68 patients pinpoints the early occurrence of recurrent respiratory infections followed by chronic lymphoproliferation, gastrointestinal manifestations, and cytopenias. Although most manifestations occur by age 15, adult-onset and asymptomatic courses were documented. Bronchiectasis was observed in 24/40 APDS1 patients who received a CT-scan compared with 4/15 APDS2 patients. By age 20, half of the patients had received at least one immunosuppressant, but 2–3 lines of immunosuppressive therapy were not unusual before age 10. Response to rapamycin was rated by physician visual analog scale as good in 10, moderate in 9, and poor in 7. Lymphoproliferation showed the best response (8 complete, 11 partial, 6 no remission), while bowel inflammation (3 complete, 3 partial, 9 no remission) and cytopenia (3 complete, 2 partial, 9 no remission) responded less well. Hence, non-lymphoproliferative manifestations should be a key target for novel therapies. This report from the ESID-APDS registry provides comprehensive baseline documentation for a growing cohort that will be followed prospectively to establish prognostic factors and identify patients for treatment studies.

Are fashion models a group at risk for eating disorders and substance abuse?

PubMed

Santonastaso, Paolo; Mondini, Silvia; Favaro, Angela

2002-01-01

Few studies to date have investigated whether in fact the prevalence of eating disorders (ED) and/or use of illicit drugs is higher among models than among other groups of females. A group of 63 professional fashion models of various nationalities were studied by means of self-reported questionnaires. They were compared with a control group of 126 female subjects recruited from the general population. Fashion models weigh significantly less than controls, but only a small percentage of them uses unhealthy methods to control their weight. The current frequency of full-syndrome ED did not differ between the groups, but partial-syndrome ED were significantly more common among fashion models than among controls. Current substance use or alcohol abuse was reported by 35% of fashion models and 12% of controls. Our findings suggest that fashion models are more at risk for partial ED and use of illicit drugs than females in the general population. Copyright 2002 S. Karger AG, Basel

Low-Tidal-Volume Ventilation in the Acute Respiratory Distress Syndrome

PubMed Central

Malhotra, Atul

2008-01-01

A 55-year-old man who is 178 cm tall and weighs 95 kg is hospitalized with community-acquired pneumonia and progressively severe dyspnea. His arterial oxygen saturation while breathing 100% oxygen through a face mask is 76%; a chest radiograph shows diffuse alveolar infiltrates with air bronchograms. He is intubated and receives mechanical ventilation; ventilator settings include a tidal volume of 1000 ml, a positive end-expiratory pressure (PEEP) of 5 cm of water, and a fraction of inspired oxygen (FiO2) of 0.8. With these settings, peak airway pressure is 50 to 60 cm of water, plateau airway pressure is 38 cm of water, partial pressure of arterial oxygen is 120 mm Hg, partial pressure of carbon dioxide is 37 mm Hg, and arterial blood pH is 7.47. The diagnosis of the acute respiratory distress syndrome (ARDS) is made. An intensive care specialist evaluates the patient and recommends changing the current ventilator settings and implementing a low-tidal-volume ventilation strategy. PMID:17855672

Genetic testing in nephrotic syndrome--challenges and opportunities.

PubMed

Gbadegesin, Rasheed A; Winn, Michelle P; Smoyer, William E

2013-03-01

Monogenic nephrotic syndrome (nephrotic syndrome caused by a single gene defect) is responsible for only a small percentage of cases of nephrotic syndrome, but information from studies of the unique cohort of patients with this form of the disease has dramatically improved our understanding of the disease pathogenesis. The use of genetic testing in the management of children and adults with nephrotic syndrome poses unique challenges for clinicians in terms of who to test and how to use the information obtained from testing in the clinical setting. In our view, not enough data exist at present to justify the routine genetic testing of all patients with nephrotic syndrome. Testing is warranted, however, in patients with congenital nephrotic syndrome (onset at 0-3 months), infantile nephrotic syndrome (onset at 3-12 months), a family history of nephrotic syndrome, and those in whom nephrotic syndrome is associated with other congenital malformations. The family and/or the patient should be given complete and unbiased information on the potential benefits and risks associated with therapy, including the reported outcomes of treatment in patients with similar mutations. Based on the data available in the literature so far, intensive immunosuppressive treatment is probably not indicated in monogenic nephrotic syndrome if complete or partial remission has not been achieved within 6 weeks of starting treatment. We advocate that family members of individuals with genetic forms of nephrotic syndrome undergo routine genetic testing prior to living-related kidney transplantation. Prospective, multicentre studies are needed to more completely determine the burden of disease caused by monogenic nephrotic syndrome, and randomized controlled trials are needed to clarify the presence or absence of clinical responses of monogenic nephrotic syndrome to available therapies.

An increased relative risk of diabetes, ischemic heart disease, atherosclerosis, and hypertension have been reported in Turner syndrome (TS) patients. No data are currently available on the prevalence of metabolic syndrome in TS subjects. We evaluated the frequency of metabolic syndrome in obese and nonobese patients with TS. We evaluated 85 TS patients (27.05 ± 11.17 years). Obesity was defined as standard deviation score body mass index (SDS-BMI) ≥ 2 or BMI ≥ 30 kg/m(2) in adult patients. We classified metabolic syndrome according to the International Diabetes Federation (IDF). Hepatic ultrasound was performed in all girls. The prevalence of metabolic syndrome was 4.7% (12.5% obese and 4.3% nonobese, P=0.16) and associated with visceral adiposity (P=0.008). Abnormalities in glucose metabolism and hypertension were not associated with genetic or therapeutic factors. The karyotype 45,X was associated with atherogenic profile. Pathological waist circumference was more frequent in girls treated with estro-progestin (P=0.03). Evidence of fatty liver was associated with metabolic syndrome (P=0.03) and insulin resistance (P=0.05). Elevated liver enzymes were found in 15 subjects and were not related to treatment or ultrasound abnormalities. Prevalence of each component of metabolic syndrome in TS patients is partially influenced by genetic makeup and treatment. Hepatosteatosis was associated with metabolic syndrome and insulin resistance, but not to elevated liver enzymes.

Obstructive sleep apnea syndrome (OSAS) is a well-recognized disorder conventionally diagnosed with an elevated apnea–hypopnea index. Prolonged partial upper airway obstruction is a common phenotype of sleep-disordered breathing (SDB), which however is still largely underreported. The major reasons for this are that cyclic breathing pattern coupled with arousals and arterial oxyhemoglobin saturation are easy to detect and considered more important than prolonged episodes of increased respiratory effort with increased levels of carbon dioxide in the absence of cycling breathing pattern and repetitive arousals. There is also a growing body of evidence that prolonged partial obstruction is a clinically significant form of SDB, which is associated with symptoms and co-morbidities which may partially differ from those associated with OSAS. Partial upper airway obstruction is most prevalent in women, and it is treatable with the nasal continuous positive pressure device with good adherence to therapy. This review describes the characteristics of prolonged partial upper airway obstruction during sleep in terms of diagnostics, pathophysiology, clinical presentation, and comorbidity to improve recognition of this phenotype and its timely and appropriate treatment.

Is the metabolic syndrome a "small baby" syndrome?: the bogalusa heart study.

2012-12-01

Metabolic syndrome has been called a "small baby syndrome," but other analyses suggest that postnatal growth is more important than birthweight, or that large babies are also at risk. The aim of this analysis was to examine whether there was a relationship between both low and high birthweight and metabolic syndrome, using multiple definitions of metabolic syndrome, and to determine whether this relationship varied by body size across the life course. Data from the Bogalusa Heart Study, a study of cardiovascular disease in children and young adults, were linked to birth certificate data. Metabolic syndrome was defined by the National Cholesterol Education Program, the International Diabetes Foundation, and the World Health Organization (WHO) definition. Small-for-gestational-age (SGA) was defined as birthweight <10(th) percentile by sex for gestational age and large-for-gestational-age (LGA) as birthweight >90(th) percentile. Birthweight-for-gestational-age was also examined as a continuous predictor. Chi-squared tests and logistic regression were used to examine the relationship between birth size and metabolic syndrome. Higher birthweight-for-gestational-age was associated with a reduced risk of metabolic syndrome, especially by the WHO definition. After adjustment for body mass index (BMI), categorized birthweight was associated with metabolic syndrome, with the protective associations with LGA being stronger than the positive associations with SGA. Among the individual components of metabolic syndrome, higher waist circumference was associated with both SGA and LGA after BMI was controlled for. Effects of SGA and BMI at any age were largely independent rather than interactive. SGA is associated with some, but not all, components of metabolic syndrome. The relationship between SGA and metabolic syndrome is partially confounded by later BMI.

Keratitis-ichthyosis-deafness (KID) syndrome is a rare ectodermal dysplasia characterized by generalized erythrokeratotic plaques, sensorineural hearing loss, and vascularizing keratitis. Cutaneous changes and hearing loss typically present in early childhood, whereas ocular symptoms present later. Mutations in the connexin (Cx) 26 gene, GJB2, are now established to underlie many of the affected cases, with the majority of patients harboring the p.D50N mutation. A rare patient demonstrating features of incomplete KID syndrome associated with an uncommon Cx26 gene mutation is described. The patient presented late in adolescence with partial features of KID syndrome. There was limited cutaneous involvement and the rare association of cystic acne. Both hearing impairment and ophthalmic involvement were mild in severity. Genetic mutation analysis revealed a previously described, rare mutation in GJB2, resulting in a glycine to arginine change at codon 12 (p.G12R). This report describes a patient exhibiting characteristics suggestive of a late-onset, incomplete form of KID syndrome with the GJB2 mutation (p.G12R). The p.G12R mutation has only been described in one other patient with KID syndrome, whose clinical presentation was not characterized.

Turner syndrome is a genetic condition resulting from the partial or complete absence of an X-chromosome in phenotypic females. Individuals with Turner syndrome often display social difficulties that are reminiscent of those associated with autistic spectrum disorders (ASD), conditions associated with empathy and mirror-neuron system (MNS) deficits. The goal of the present study was (1) to investigate the extent to which adults with Turner syndrome display autistic and empathic traits, and (2) to probe the integrity of the MNS in this neurogenetic disorder. Sixteen individuals with Turner syndrome and 16 age-, sex-, and IQ-matched controls took part in a neuropsychological assessment where the Weschler Abbreviated Scale of Intelligence, the Autism Spectrum Quotient and the Empathy Quotient were administered. Functioning of the MNS was assessed by measuring motor cortex activity with transcranial magnetic stimulation during an action-observation task. Results show that individuals with Turner syndrome do not differ significantly from controls regarding autistic or empathic traits, and present normal functioning of the MNS during action observation. Correlational analysis showed a significant positive relationship between scores on the Empathy Quotient and motor facilitation during action observation, bringing further support to the hypothesis that MNS activity is related to sociocognitive competence.

Alongside various physical symptoms, patients with Cushing's disease and Cushing's syndrome display a wide variety of neuropsychiatric and cognitive symptoms, which are indicative of involvement of the central nervous system. The aim of this review is to provide an overview of the structural brain abnormalities that are associated with Cushing's disease and Cushing's syndrome and their relation to behavioral and cognitive symptomatology. In this review, we discuss the gray matter structural abnormalities found in patients with active Cushing's disease and Cushing's syndrome, the reversibility and persistence of these changes and the white matter structural changes related to Cushing's syndrome. Recent findings are of particular interest because they provide more detailed information on localization of the structural changes as well as possible insights into the underlying biological processes. Active Cushing's disease and Cushing's syndrome is related to volume reductions of the hippocampus and in a prefrontal region involving the anterior cingulate cortex (ACC) and medial frontal gyrus (MFG). Whilst there are indications that the reductions in hippocampal volume are partially reversible, the changes in the ACC and MFG appear to be more persistent. In contrast to the volumetric findings, changes in white matter connectivity are typically widespread involving multiple tracts.

Long-distance dispersal to oceanic islands: success of plants with multiple diaspore specializations

2015-01-01

A great number of scientific papers claim that angiosperm diversification is manifested by an ample differentiation of diaspore traits favouring long-distance seed dispersal. Oceanic islands offer an ideal framework to test whether the acquisition of multiple sets of diaspore traits (syndromes) by a single species results in a wider geographic distribution. To this end, we performed floristic and syndrome analyses and found that diplochorous species (two syndromes) are overrepresented in the recipient flora of the Azores in contrast to that of mainland Europe, but not to mainland Portugal. An additional analysis of inter-island colonization showed a general trend of a higher number of islands colonized by species with a single syndrome (monochorous) and two syndromes than species with no syndrome (unspecialized). Nevertheless, statistical significance for differences in colonization is meagre in some cases, partially due to the low proportion of diplochorous species in Europe (244 of ∼10 000 species), mainland Portugal (89 of 2294 species), and the Azores (9 of 148 species), Canaries (17 of 387 lowland species) and Galápagos (18 of 313 lowland species). Contrary to expectations, this first study shows only a very marginal advantage for long-distance dispersal of species bearing multiple syndromes. PMID:26174146

Successful pregnancy after mucinous cystic neoplasm with invasive carcinoma of the pancreas in a patient with polycystic ovarian syndrome: a case report.

The incidence of invasive cancer within a mucinous cystic neoplasm of the pancreas varies between 6 and 36%. Polycystic ovarian syndrome is a disorder characterized by hyperandrogenism and anovulatory infertility. One surgical treatment that can restore endocrine balance and ovulation in polycystic ovarian syndrome is partial ovarian destruction. Successful pregnancies following preconception pancreaticoduodenectomies (Whipple procedures) and chemoradiation to treat pancreatic neoplasms have been reported rarely but none were diagnosed with pre-cancer polycystic ovarian syndrome-associated infertility. Gemcitabine is an antimetabolite drug used for the treatment of pancreatic cancer that can have profound detrimental effects on oogenesis and ovarian function. Whether the ovarian destructive property of gemcitabine could act as a method to restore ovulation potential in polycystic ovarian syndrome is unknown. A 40-year-old white American woman with a history of pancreatic cancer treatment with a Whipple procedure and chemoradiation with gemcitabine had a successful pregnancy after years of pre-cancerous anovulatory infertility and polycystic ovarian syndrome. She received no fertility agents and delivered full term via a spontaneous vaginal delivery with no pregnancy complications. Gemcitabine treatment for pancreatic cancer may result in resumption of ovulation in women with polycystic ovarian syndrome and these women should be counseled accordingly.

An adrenal tumor was discovered fortuitously in a patient with no clinical features of Cushing's syndrome. On adrenal imaging, there was good uptake in the nodule but no visualization of the contralateral adrenal. The latter was seen, however, in a second scan performed under ACTH treatment. In the hormone assessment, basal cortisol and 17-hydroxycorticoids were normal and cortisol diurnal variation was near normal, but a dexamethasone suppression test and ACTH responses to metyrapone and insulin hypoglycemia were abnormal. Eight months after excision of a spongiocytic-type adenoma, the remaining adrenal was visible on scintigram and the hormonal tests were normal. Thismore » pattern suggests that the clinical Cushing's syndrome was enough to partially suppress ACTH and, consequently, visualization of the contralateral gland.« less

Laparoscopic cholecystectomy is the standard of care for cholelithiasis as well as cholecystitis. However, in the setting of Mirizzi syndrome or gangrenous cholecystitis where the critical view cannot be ascertained, subtotal cholecystectomy may be necessary. Using the robot-assisted approach, difficult cholecystectomies can be performed upfront without need for partial cholecystectomy. Even in the setting of Mirizzi syndrome where severe scarring and fibrosis are evident, definitive cholecystectomy and takedown of the cholechystocholedochal fistula can be performed in a safe and feasible fashion following successful endoscopic common bile duct stent placement. The purposes of this report are to review the history of Mirizzi syndrome as well as its traditional and novel treatment techniques and highlight technical pearls of the robotic approach to this diagnosis.

Ectodermal dysplasia syndrome is a hereditary disease of ectodermal origin. Appearances of nail dystrophy, alopecia or hypotrichosis, saddle nose deformity, and palmoplantar hyperkeratosis are usually associated with a lack of sweat glands as well as partial or complete absence of teeth. These manifestations are usually corrected only with oral rehabilitation by mounting dentures. In this study, plastic rehabilitation was developed to correct the special features of patients with ectodermal dysplasia. Four men and 1 woman with ectodermal dysplasia syndrome were treated. Four patients showed dysostosis of the midface, and rhinoplasty with costal bone was performed, whereas cosmetic operation aiming to repair soft tissue defects was adopted for the last patient. After plastic corrections, all 5 patients were satisfied with the results and had no social embarrassment.

Sickle cell disease is a chronic hematologic disease with variable but often severe systemic symptoms. In this report, we describe a 6-year-old boy presenting with acute bowel pseudo-obstruction. During this episode, previously undiagnosed sickle cell disease was discovered upon peripheral blood smear analysis. The condition was therefore interpreted as a massive intestinal vaso-occlusive crisis or "girdle syndrome". Conservative treatment with hydration therapy, analgesia and a manual partial exchange transfusion was initiated. The patient fully recovered within 5 days. Girdle syndrome is a rare but severe adverse event associated with sickle cell disease that must be considered as differential diagnosis in patients with sickle cell disease. © Georg Thieme Verlag KG Stuttgart · New York.

Sheehan’s syndrome, first described in 1937, is characterised by postpartum haemorrhage, pituitary necrosis, lactational failure and hypopitutarism. Presentation is variable and late presentations are not unusual due to partial ischaemic injury of the pituitary and gradual loss of endocrine function. A history of postpartum haemorrhage is usual but in some cases it is not elicited. Presentations such as malaise, fatigue, hypoglycaemia, decline in cognition, hyponatraemia, pancytopoenia, osteoporosis, secondary infertility, confusion and coma have all been reported. Two interesting cases of Sheehan’s syndrome are presented that were diagnosed in the eighth decade; one due to atypical presentation of recurrent hyponatraemia and confusion, another from hypoglycaemic coma and symptoms of malaise and lethargy.

The aim of this study was to describe a case of severe keratitis-ichthyosis-deafness (KID) syndrome with ocular surface squamous neoplasia. The affected patient underwent complete ocular and systemic examinations. The molecular studies included polymerase chain reaction amplification and automated DNA sequencing of the complete gap junction beta-2 (GJB2) gene coding sequence. A 30-year-old man presented with generalized erythro-hyperkeratosis and deafness and complaints of decreased visual acuity, tearing, and photophobia. Ophthalmic examination showed corneal erosion, vascularization, and a gray gelatinous lesion partially covering the right cornea, suggestive of squamous neoplasia. The clinical features were characteristic of KID syndrome. This diagnosis was confirmed with a DNA analysis showing the pathogenic variant p.D50N in the GJB2 gene. Presumed squamous neoplasia was treated with topical interferon α2b. KID syndrome is a very rare disease that has been reported with an incremental incidence of squamous cell carcinoma of the mucous membranes and skin (12%-15%). Here, we presented a case of severe systemic KID syndrome with ocular surface squamous neoplasia.

[Takotsubo syndrome. Transient left ventricular dyskinesia].

PubMed

Pérez Pérez, F M; Sánchez Salado, J

2014-03-01

The Takotsubo syndrome, also called transient apical dyskinesia syndrome, was first described in Japan in the 1990s. It is a rare entity found in almost 1% of all patients with suspicion of acute coronary syndrome. It usually affects postmenopausal women with a few cardiovascular risk factors. It is characterized by angina-type chest pain, electrocardiographic changes, elevation of the enzymes of myocardial injury, absence of coronary obstruction on angiography, and a characteristic left ventricular anteroapical dyskinesia, which returns to normal within a few days. Severe emotional stress is the most common trigger for this syndrome. The aetiopathogenesis of this syndrome remains to be defined. This syndrome has been considered a clinical condition since 2001, when a series of 88 cases was published. It is a disease with a partially known mechanism, characterised by the morphology adopted by the left ventricle secondary to hypokinesis or dyskinesia of the apical segments, and hypercontractility of basal segments. Unlike acute coronary syndrome, patients with left ventricle dysfunction do not have atherothrombotic disease in the coronary arteries. In addition, the alterations described are reversible. Some clinical diagnostic criteria have been proposed, although they are still controversial, as well as in the complementary examinations required for diagnosis.

Diseases and partial mortality in Montastraea annularis species complex in reefs with differing environmental conditions (NW Caribbean and Gulf of Mexico).

2005-01-25

We documented the prevalence of diseases, syndromes and partial mortality in colonies of the Montastraea annularis species complex on 3 reefs, and tested the assumption that a higher prevalence of these parameters occurs when reefs are closer to point-sources of pollution. One reef was isolated from the impact of local factors with the exception of fishing, 1 potentially influenced by local industrial pollutants, and 1 influenced by local urban pollution. Two reefs were surveyed in 1996 and again in 2001 and 1 in 1998 and again in 2001. In 2001, colonies on all reefs had a high prevalence of the yellow-band syndrome and a relatively high degree of recent partial mortality, while the prevalence of black-band and white-plague diseases was low although a new sign, that we named the thin dark line, had relatively high prevalence in all reefs. As no direct relationship was found between disease prevalence and local environmental quality, our results open the possibility that regional and/or global factors may already be playing an important role in the prevalence of coral disease in the Caribbean, and contradict the theory that coral disease prevalence is primarily related to local environmental degradation. Reasons that may partially explain these findings are the high level of potential pathogen connectivity within the Caribbean as a result of its circulation patterns coupled to the large land-derived pollutants and pathogens input into this Mediterranean sea, together with the surface water warming effects which stress corals and enhance pathogen activity.

Immunoglobulin levels of individual classes and IgG subclasses and the occurrence of homogeneous immunoglobulins--paraproteins--were studied longitudinally in the sera of three patients with the Wiskott-Aldrich syndrome; Common findings in all three patients were great variations in the immunoglobulin levels, restricted heterogeneity of the immunoglobulins, the frequent appearance of transient homogeneous immunoglobulins and the presence of serum antibodies against bovine milk proteins. A partial and selective deficiency involving mainly the T immune system is postulated as an explanation for these findings. Images Fig. 2 Fig. 3 Fig. 4 PMID:954233

This article aims to review the clinical management strategies available for the rare iridocorneal endothelial syndrome. The different clinical variations as well as the imaging techniques available to aid diagnosis are discussed. We then present the evidence available to help the reader to understand how the condition can be managed medically and also the important surgical aspects of treatment. This involves raised intraocular pressure management in addition to the visual management options of partial or full thickness keratoplasty. We hope that this review provides an exhaustive but also succinct review of the literature available on what is a rare and difficult condition to treat. PMID:29670326

Intraatrial baffle repair of anomalous systemic venous return without hepatic venous drainage in heterotaxy syndrome.

2010-08-01

A 7-month-old boy with heterotaxy syndrome had partial atrioventricular septal defect and interrupted inferior vena cava with hemiazygos continuation to a left superior vena cava. The left side of the common atrium receiving all the venous drainage was in connection with the left ventricle and the aorta. The small atrium and the proximity of the pulmonary and hepatic vein orifices precluded complete baffling. This report describes an intraatrial baffle repair of anomalous systemic venous return without hepatic venous drainage. This resulted in good oxygenation postoperatively, with oxygen saturation ranging from 93% to 98%.

Male partial hypogonadotrophic hypogonadism with gynaecomastia and metabolic syndrome.

2012-02-01

The causal association of childhood obesity and hypogonadotrophic hypogonadism needs to be studied to unravel the cause and effect relationship between the two conditions. The relationship of hypogonadism to the Metabolic Syndrome (MetS) remains valid even when using different definitions of MetS, and following the patients prospectively for over 10 years. This is a case of 19 years male who presented with micropenis, marked gynaecomastia and weight gain. Childhood obesity and family history of diabetes predisposed him to future MetS. Presence of micropenis reflects intrauterine hypogonadotrophic hypogonadism. Both entities exacerbated each other.

Five Indian isolates of egg drop syndrome (EDS) 1976 virus and the reference strain 127 were compared by restriction enzyme analysis of viral DNA, and the hexon gene amplified by polymerase chain reaction. Using these techniques, no differences were seen among these viruses. However, partial sequencing of the hexon gene revealed major differences (4.6%) in one of the isolates sequenced, EDS Kerala. Phylogenetic analysis also placed this isolate in a different lineage compared with the other isolates. The need for constant monitoring of the genetic nature of the field isolates of EDS viruses is emphasized.

Cushing syndrome (CS), due to an ACTH-secreting pituitary adenoma, adrenal tumors, or ectopic ACTH secretion, causes hypercortisolism. CS is associated with major morbidity, especially metabolic and cardiovascular complications, osteoporosis, psychiatric changes, and cognitive impairment. Despite biochemical "cure" of hypercortisolism and clinical improvement after effective treatment, these complications are only partially reversible. Exacerbation of prior autoimmune diseases is also seen. All of these lead to quality of life impairment and increased mortality. This review addresses the main comorbidities and long-term consequences of CS despite clinical and biochemical "cure". Copyright © 2013 SEEN. Published by Elsevier Espana. All rights reserved.

Clival Malformations in CHARGE Syndrome.

Mahdi, E S; Whitehead, M T

2018-06-01

CHARGE syndrome is a multisystemic congenital disorder, most commonly including coloboma, heart malformations, choanal atresia, developmental delay, and genital and ear anomalies. The diagnostic criteria for CHARGE syndrome have been refined with time. However, limited reports describe skull base and craniocervical junction abnormalities. Recently, a coronal clival cleft has been identified in association with CHARGE syndrome. The aim of our study was to assess the prevalence of clival pathology in CHARGE syndrome. In this retrospective study, the CT/MR imaging data base at a single academic children's hospital was queried for the phrase "CHARGE syndrome" during a 17-year period (2001-2017). Electronic medical records were reviewed to confirm the diagnosis. Images were assessed for skull base anomalies, specifically clival hypoplasia and dysplasia. The search yielded 42 examinations (21 CTs and 21 MRIs) from 15 distinct patients (mean age, 4.1 ± 5.6 years; range, 2 days to 19 years). CHARGE syndrome diagnosis was confirmed either by clinical and genetic testing ( n = 6) or by clinical diagnosis only ( n = 9). A coronal clival cleft was identified in 87% of patients (37 examinations, n = 13 patients), either partial (53%) or complete (33%). Clival hypoplasia without clefting was present in all 5 examinations from the remaining 2 patients. Clival pathology is universal in CHARGE syndrome. Coronal clival clefts are extremely common, representing a useful additional diagnostic finding. Detection of a clival cleft should alert the radiologist to examine the palate, choana, eyes, ears, and olfactory centers for other signs of CHARGE syndrome. © 2018 by American Journal of Neuroradiology.

Overgrowth syndromes: the practical clinical approach. Excessive growth can be present in a variety of medical conditions as result of abnormal fetal metabolism (i.e., maternal gestational diabetes) or of an overgrowth syndrome. Within this latter group of diseases, a LGA newborn requires a complex differential diagnosis encompassing several syndromes, such as Beckwith-Wiedemman, Sotos, Weaver, Simpson-Golabi-Behmel, Perlman, and Bannayan-Riley-Ruvalcaba. Partial or global overgrowth, other dysmorphisms, abdominal organs anomalies, as well as benign and malignant tumors are the common issues to examine for the diagnosis and the monitoring of all these disorders. The molecular bases of these conditions, even if partially known so far, can help in explaining the clinical features and prognosis. The diagnostic course, the genetic investigations and the follow-up of a LGA patient will be presented during the seminar. A wide clinical spectrum from esophageal atresia to VACTERL association. Oesophageal atresia (OA) occurs approximately in 1 in 3000 live births. It can be clinically divided into isolated and syndromic, when associated with other features. The aetiology is largely unknown and is likely to be multifactorial, however, various clues have been uncovered in animal experiments particularly defects in the expression of the gene Sonic hedgehog (Shh). The vast majority of cases are sporadic and the recurrence risk for siblings is 1%. Survival is directly related to birth weight and to the presence of a major cardiac defect. The VACTERL association refers to anomalies of the bony spinal column (V), atresias in the gastrointestinal tract (A), congenital heart lesions (C), tracheoesophageal defects (TE), renal and distal urinary tract anomalies (R) and limb lesions (L). The overall phenotype of a series of newborn patients we observed may vary widely, reflecting the aetiologic heterogeneity of this group of conditions. Therefore, possible additional defects must be accurately investigated in all newborns with OA.

BACKGROUND Idiopathic partial epilepsies of childhood (IPE) affect a considerable proportion of children. Three main electroclinical syndromes of IPE are the Benign Childhood Epilepsy with Centro-temporal Spikes (BECTS), Panayiotopoulos Syndrome (PS), and Childhood Epilepsy with Occipital Paroxysms (CEOP). In this study we investigated the long-term prognosis of patients with IPE and discussed the semiological and electroencephalography (EEG) data in terms of syndromic characteristics. MATERIAL AND METHODS This study included a group of consecutive patients with IPE who had been followed since 1990. Demographic and clinical variables were investigated. Patients were divided into 3 groups - A: Cases suitable for a single IPE (BECTS, PS and CEOP); B: cases with intermediate characteristics within IPEs; and C: cases with both IPE and IGE characteristics. Long-term data regarding the individual seizure types and EEG findings were re-evaluated. RESULTS A total of 61 patients were included in the study. Mean follow-up duration was 7.8 ± 4.50 years. The mean age at onset of seizures was 7.7 years. There were 40 patients in group A 40, 14 in group B, and 7 in group C. Seizure and EEG characteristics were also explored independently from the syndromic approach. Incidence of autonomic seizures is considerably high at 2-5 years and incidence of oromotor seizures is high at age 9-11 years. The EEG is most abnormal at 6-8 years. The vast majority (86%) of epileptic activity (EA) with parietooccipital is present at 2-5 years, whereas EA with fronto-temporal or multiple sites become more abundant between ages 6 and 11. CONCLUSIONS Results of the present study provide support for the age-related characteristics of the seizures and EEGs in IPE syndromes. Acknowledgement of those phenomena may improve the management of IPEs and give a better estimate of the future consequences.

A ‘Down Syndrome critical region’ (DSCR) sufficient to induce the most constant phenotypes of Down syndrome (DS) had been identified by studying partial (segmental) trisomy 21 (PT21) as an interval of 0.6–8.3 Mb within human chromosome 21 (Hsa21), although its existence was later questioned. We propose an innovative, systematic reanalysis of all described PT21 cases (from 1973 to 2015). In particular, we built an integrated, comparative map from 125 cases with or without DS fulfilling stringent cytogenetic and clinical criteria. The map allowed to define or exclude as candidates for DS fine Hsa21 sequence intervals, also integrating duplication copy number variants (CNVs) data. A highly restricted DSCR (HR-DSCR) of only 34 kb on distal 21q22.13 has been identified as the minimal region whose duplication is shared by all DS subjects and is absent in all non-DS subjects. Also being spared by any duplication CNV in healthy subjects, HR-DSCR is proposed as a candidate for the typical DS features, the intellectual disability and some facial phenotypes. HR-DSCR contains no known gene and has relevant homology only to the chimpanzee genome. Searching for HR-DSCR functional loci might become a priority for understanding the fundamental genotype-phenotype relationships in DS. PMID:27106104

Unravelling the effects of age, period and cohort on metabolic syndrome components in a Taiwanese population using partial least squares regression

PubMed Central

2011-01-01

Background We investigate whether the changing environment caused by rapid economic growth yielded differential effects for successive Taiwanese generations on 8 components of metabolic syndrome (MetS): body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (FPG), triglycerides (TG), high-density lipoprotein (HDL), Low-density lipoproteins (LDL) and uric acid (UA). Methods To assess the impact of age, birth year and year of examination on MetS components, we used partial least squares regression to analyze data collected by Mei-Jaw clinics in Taiwan in years 1996 and 2006. Confounders, such as the number of years in formal education, alcohol intake, smoking history status, and betel-nut chewing were adjusted for. Results As the age of individuals increased, the values of components generally increased except for UA. Men born after 1970 had lower FPG, lower BMI, lower DBP, lower TG, Lower LDL and greater HDL; women born after 1970 had lower BMI, lower DBP, lower TG, Lower LDL and greater HDL and UA. There is a similar pattern between the trend in levels of metabolic syndrome components against birth year of birth and economic growth in Taiwan. Conclusions We found cohort effects in some MetS components, suggesting associations between the changing environment and health outcomes in later life. This ecological association is worthy of further investigation. PMID:21619595

Usher syndrome is a heterogeneous group of autosomal recessive disorders that combines variably severe congenital neurosensory hearing impairment with progressive night-blindness and visual loss similar to that in retinitis pigmentosa. Usher syndrome type I is distinguished by profound congenital (preverbal) deafness and retinal disease with onset in the first decade of life. Usher syndrome type II is characterized by partial hearing impairment and retinal dystrophy that occurs in late adolescence or early adulthood. The chromosomal assignment and the regional localization of the genetic mutation(s) causing the Usher syndromes are unknown. We analyzed a panel of polymorphic genomic markers for linkage to the disease gene among six families with Usher syndrome type I and 22 families with Usher syndrome type II. Significant linkage was established between Usher syndrome type II and the DNA marker locus THH33 (D1S81), which maps to chromosome 1q. The most likely location of the disease gene is at a map distance of 9 cM from THH33 (lod score 6.5). The same marker failed to show linkage in families segregating an allele for Usher syndrome type I. These data confirm the provisional assignment of the locus for Usher syndrome type II to the distal end of chromosome 1q and demonstrate that the clinical heterogeneity between Usher types I and II is caused by mutational events at different genetic loci. Regional localization has the potential to improve carrier detection and to provide antenatal diagnosis in families at risk for the disease.

Awareness of the spectrum of clinical manifestations of systemic lupus erythematosus (SLE), especially uncommon changes, is essential for diagnosis and effective management of patients. A 26-year-old Chinese man with SLE initially manifested cutaneous papulonodular mucinosis and developed acute Guillain-Barré syndrome and class V lupus nephritis 2 years later. His cutaneous nodules had not been idententified for 2 years and were resected by surgical procedures twice until SLE was diagnosed. The kidney biopsy revealed class V lupus nephritis. The patient responded well to a short course of intravenous immunoglobulins and his muscle strength almost completely recovered. So far, he has undergone five cycles of cyclophosphamide combined with hydroxychloroquine and tapering prednisone, resulting in partial remission of lupus nephritis and disappearance of hypocomplementemia. We reported a rare case of male patient with SLE with manifestation of class V lupus nephritis, Guillain-Barré syndrome and papulonodular mucinosis.

OBJECTIVES The objective of this study was to determine the (1) incidence of short bowel syndrome in very low birth weight (<1500 g) infants, (2) associated morbidity and mortality during initial hospitalization, and (3) impact on short-term growth and nutrition in extremely low birth weight (<1000 g) infants. METHODS Infants who were born from January 1, 2002, through June 30, 2005, and enrolled in the National Institute of Child Health and Human Development Neonatal Research Network were studied. Risk factors for developing short bowel syndrome as a result of partial bowel resection (surgical short bowel syndrome) and outcomes were evaluated for all neonates until hospital discharge, death, or 120 days. Extremely low birth weight survivors were further evaluated at 18 to 22 months’ corrected age for feeding methods and growth. RESULTS The incidence of surgical short bowel syndrome in this cohort of 12 316 very low birth weight infants was 0.7%. Necrotizing enterocolitis was the most common diagnosis associated with surgical short bowel syndrome. More very low birth weight infants with short bowel syndrome (20%) died during initial hospitalization than those without necrotizing enterocolitis or short bowel syndrome (12%) but fewer than the infants with surgical necrotizing enterocolitis without short bowel syndrome (53%). Among 5657 extremely low birth weight infants, the incidence of surgical short bowel syndrome was 1.1%. At 18 to 22 months, extremely low birth weight infants with short bowel syndrome were more likely to still require tube feeding (33%) and to have been rehospitalized (79%). Moreover, these infants had growth delay with shorter lengths and smaller head circumferences than infants without necrotizing enterocolitis or short bowel syndrome. CONCLUSIONS Short bowel syndrome is rare in neonates but has a high mortality rate. At 18 to 22 months’ corrected age, extremely low birth weight infants with short bowel syndrome were more likely to have growth failure than infants without short bowel syndrome. PMID:18762491

The development of medical countermeasures against acute and delayed multi-organ injury requires animal models predictive of the human response to radiation and its treatment. Late chronic injury is a well-known feature of radiation nephropathy, but acute kidney injury has not been reported in an appropriate animal model. We have established a single-fraction partial-body irradiation model with minimal marrow sparing in non-human primates. Subject-based medical management was used including parenteral fluids according to prospective morbidity criteria. We show herein that 10 or 11 Gy exposures caused both acute and chronic kidney injury. Acute and chronic kidney injury appear to be dose-independent between 10 and 11 Gy. Acute kidney injury was identified during the first 50 days postirradiation and appeared to resolve before the occurrence of chronic kidney injury, which was progressively more severe up to 180 days postirradiation, which was the end of the study. These findings show that mitigation of the acute radiation syndrome by medical management will unmask delayed late effects that occur months after partial-body irradiation. They further emphasize that both acute and chronic changes in kidney function must be taken into account in the use and timing of mitigators and medical management for acute radiation syndrome and delayed effects of acute radiation exposure (DEARE).

To evaluate the usefulness of the (75)SeHCAT abdominal retention (AR) measurement in the early diagnosis of diarrhea syndrome (DS). Thirty-seven patients with diarrhea syndrome within the first month of evolution were prospectively evaluated. The (75)Se-SeHCAT abdominal retention was measured 4 and 7 days post-administration of 0.01 mCi of (75)SeHCAT. The test was performed prior to treatment and at 3 months when the baseline study was positive. The test was considered positive if the RA was <25% at 4(th) and <10% on the 7th day. The patients were visited at 3 months. Depending on the response, 3 groups were established: a) complete response: normalization of stool frequency, b) partial response, decrease of frequency or c) no response. Group A: The AR of (75)Se-SEHCAT was normal in 21 patients. Six were diagnosed of colonic diverticulosis, 8 of irritable bowel syndrome, 1 of lymphocytic colitis, 1 of post-gastroenteritis syndrome, 1 of celiac disease and 1 of stenosis of the cardia. Four are still under study. Group B: The AR of (75)Se-SEHCAT decreased in 16 patients. All showed abnormal AR at day 7 and all but 1 at day 4. Following administration of cholestyramine resin, 8 (50%) presented partial response and 8 (50%) complete response. At 3 months, AR had increased at day 4 and 9 at day 7. The measurement of (75)SEHCAT abdominal retention allows the early diagnosis of bile acid malabsorption in 43% of the patients with DS. Measurement at 7 days seems more accurate than that at 4 days.

Genotype-phenotype analysis of recombinant chromosome 4 syndrome: an array-CGH study and literature review

2013-01-01

Background Recombinant chromosome 4, a rare constitutional rearrangement arising from pericentric inversion, comprises a duplicated segment of 4p13~p15→4pter and a deleted segment of 4q35→4qter. To date, 10 cases of recombinant chromosome 4 have been reported. Result We describe the second case in which array-CGH was used to characterize recombinant chromosome 4 syndrome. The patient was a one-year old boy with consistent clinical features. Conventional cytogenetics and FISH documented a recombinant chromosome 4, derived from a paternal pericentric inversion, leading to partial trisomy 4p and partial monosomy of 4q. Array-CGH, performed to further characterize the rearranged chromosome 4 and delineate the breakpoints, documented a small (4.36 Mb) 4q35.1 terminal deletion and a large (23.81 Mb) 4p15.1 terminal duplication. Genotype-phenotype analysis of 10 previously reported cases and the present case indicated relatively consistent clinical features and breakpoints. This consistency was more evident in our case and another characterized by array-CGH, where both showed the common breakpoints of p15.1 and q35.1. A genotype-phenotype correlation study between rec(4), dup(4p), and del(4q) syndromes revealed that urogenital and cardiac defects are probably due to the deletion of 4q whereas the other clinical features are likely due to 4p duplication. Conclusion Our findings support that the clinical features of patients with rec(4) are relatively consistent and specific to the regions of duplication or deletion. Recombinant chromosome 4 syndrome thus appears to be a discrete entity that can be suspected on the basis of clinical features or specific deleted and duplicated chromosomal regions. PMID:23639048

Atopic dermatitis (AD), Netherton syndrome (NS) and peeling skin syndrome type B (PSS) may show some clinical phenotypic overlap. Corneodesmosomes are crucial for maintaining stratum corneum integrity and the components' localization can be visualized by immunostaining tape-stripped corneocytes. In normal skin, they are detected at the cell periphery. To determine whether AD, NS, PSS and ichthyosis vulgaris (IV) have differences in the corneodesmosomal components' distribution and corneocytes surface areas. Corneocytes were tape-stripped from a control group (n=12) and a disease group (37 AD cases, 3 IV cases, 4 NS cases, and 3 PSS cases), and analyzed with immunofluorescent microscopy. The distribution patterns of corneodesmosomal components: desmoglein 1, corneodesmosin, and desmocollin 1 were classified into four types: peripheral, sparse diffuse, dense diffuse and partial diffuse. Corneocyte surface areas were also measured. The corneodesmosome staining patterns were abnormal in the disease group. Other than in the 3 PSS cases, all three components showed similar patterns in each category. In lesional AD skin, the dense diffuse pattern was prominent. A high rate of the partial diffuse pattern, loss of linear cell-cell contacts, and irregular stripping manners were unique to NS. Only in PSS was corneodesmosin staining virtually absent. The corneocyte surface areas correlated significantly with the rate of combined sparse and dense diffuse patterns of desmoglein 1. This method may be used to assess abnormally differentiated corneocytes in AD and other diseases tested. In PSS samples, tape stripping analysis may serve as a non-invasive diagnostic test.

This article summarizes data submitted to the U.S. Food and Drug Administration for marketing approval of azacitidine as injectable suspension (Vidaza, Pharmion Corporation, Boulder, CO) for treatment of patients with myelodysplastic syndrome. In one phase 3 controlled trial, 191 study subjects were randomized to treatment with azacitidine or to observation; an additional 120 patients were treated with azacitidine in two phase 2 single arm studies. The primary efficacy end point was the overall response rate, defined as complete or partial normalization of peripheral blood counts and bone marrow blast percentages for at least 4 weeks. In the controlled trial, the overall response rate was 15.7% in the azacitidine treatment group; there were no responders in the observation group (P < 0.0001). Response rates were similar in the two single arm studies. During response patients stopped being red cell or platelet transfusion dependent. Median duration of responses was at least 9 months. An additional 19% of azacitidine-treated patients had less than partial responses, most becoming transfusion independent. The most common adverse events attributed to azacitidine were gastrointestinal, hematologic, local (injection site), and constitutional. There were no azacitidine-related deaths. On May 19, 2004 the U.S. Food and Drug Administration approved azacitidine as injectable suspension for treatment of patients with the following myelodysplastic syndrome subtypes: refractory anemia or refractory anemia with ringed sideroblasts (if accompanied by neutropenia or thrombocytopenia or requiring transfusions), refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, and chronic myelomonocytic leukemia. Full prescribing information is available at http://www.fda.gov/cder/foi/label/2004/050794lbl.pdf. Azacitidine is the first agent approved for treatment of myelodysplastic syndrome.

Although commonly interpreted as a marker of episodic memory during neuropsychological exams, relatively little is known regarding the neurobehavior of "total learning" immediate recall scores. Medial temporal lobes are clearly associated with delayed recall performances, yet immediate recall may necessitate networks beyond traditional episodic memory. We aimed to operationalize cognitive and neuroanatomic correlates of total immediate recall in several aging syndromes. Demographically-matched neurologically normal adults (n=91), individuals with Alzheimer's disease (n=566), logopenic variant primary progressive aphasia (PPA) (n=34), behavioral variant frontotemporal dementia (n=97), semantic variant PPA (n=71), or nonfluent/agrammatic variant PPA (n=39) completed a neurocognitive battery, including the CVLT-Short Form trials 1-4 Total Immediate Recall; a majority subset also completed a brain MRI. Regressions covaried for age and sex, and MMSE in cognitive and total intracranial volume in neuroanatomic models. Neurologically normal adults demonstrated a heterogeneous pattern of cognitive associations with total immediate recall (executive, speed, delayed recall), such that no singular cognitive or neuroanatomic correlate uniquely predicted performance. Within the clinical cohorts, there were syndrome-specific cognitive and neural associations with total immediate recall; e.g., semantic processing was the strongest cognitive correlate in svPPA (partial r=0.41), while frontal volumes was the only meaningful neural correlate in bvFTD (partial r=0.20). Medial temporal lobes were not independently associated with total immediate recall in any group (ps>0.05). Multiple neurobehavioral systems are associated with "total learning" immediate recall scores that importantly differ across distinct clinical syndromes. Conventional memory networks may not be sufficient or even importantly contribute to total immediate recall in many syndromes. Interpreting learning scores as equivalent to episodic memory may be erroneous. Copyright © 2017 Elsevier Ltd. All rights reserved.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome is characterized by symmetrical synovitis predominantly involving the wrists, and is associated with marked pitting edema of the dorsum of the hands. Although the etiology of RS3PE syndrome is still unknown, several putative associations with malignancies and hematological disorders have been reported. Myelodysplastic syndrome (MDS) is characterized by infective hematopoiesis with possible transformation to leukemia; however, an association between RS3PE syndrome and MDS has been rarely reported. Here, we describe a 67-year-old man with MDS with refractory anemia who developed RS3PE syndrome 3 months after the diagnosis of MDS. The patient presented with polyarthritis with pitting edema at the dorsum of the hands, the elevated serum levels of C-reactive protein and a proinflammatory cytokine, interleukin-6, and the elevated plasma levels of vascular endothelial growth factor (VEGF). VEGF has been shown to be involved in the pathogenesis of RS3PE syndrome. Treatment with low doses of corticosteroids resulted in the regression of polyarthritis and pitting edema of the dorsum of the hands, as well as a reduction in the elevated levels of plasma VEGF. Partial resolution of refractory anemia was also observed with steroid therapy. In summary, RS3PE syndrome developed shortly after MDS was identified in this patient. The sequence of clinical events suggests that MDS-mediated immunological abnormalities including inflammatory cytokine induction may be responsible for the association between MDS and RS3PE syndrome. Patients with RS3PE syndrome should be screened for hematological disorders that promote proinflammatory mediators.

Joubert syndrome is a rare autosomal recessive disorder with partial or complete agenesis of cerebellar vermis. This syndrome is identified mainly by the presence of molar tooth sign in magnetic resonance imaging of the brain since it has a varied phenotypic presentation. Of the 200 cases reported so far in the literature, only three reports show the presence of autistic symptoms in siblings suggesting a link between the cerebellar vermis and autistic spectrum disorders. In this case report of two siblings, the female child satisfied the criterion for autistic spectrum disorder in accordance with Diagnostic and Statistical Manual of Mental Disorders Fifth Editon. The boy showed developmental delay with autistic features (not amounting to diagnostic threshold). This report is important in that it adds evidence to the literature that abnormalities of cerebellum are involved in the cognitive development and autistic symptoms.

The authors report a case of partial Currarino syndrome in a three and a half year old child with a left hemisacrum agenesis and a presacral mature teratoma. The special aspect of the observation was the apparition of repetitive polymicrobial purulent meningitis (Escherichia coli, Streptococcus B, Haemophilus influenzae) treated several times with non-specific antibiotics without normalization of CSF, particularly the CSF glucose, which remained low, justifying the use of an antimycobacterial treatment, especially since there was no local or general cause explaining the relapse. During a relapse of meningitis after ten months of antituberculosis treatment, the teratoma was discovered by a spine MRI done to detect any cerebrospinal defect. The authors insist on the fact that the Currarino syndrome must be investigated in case of repetitive purulent meningitis after ruling out the usual causes of meningitis.

Kindler syndrome is an autosomal recessive disorder characterized by skin atrophy and blistering. It results from loss-of-function mutations in the FERMT1 gene encoding the focal adhesion protein, fermitin family homolog-1. How and why deficiency of fermitin family homolog-1 results in skin atrophy and blistering are unclear. In this study, we investigated the epidermal basement membrane and keratinocyte biology abnormalities in Kindler syndrome. We identified altered distribution of several basement membrane proteins, including types IV, VII, and XVII collagens and laminin-332 in Kindler syndrome skin. In addition, reduced immunolabeling intensity of epidermal cell markers such as beta1 and alpha6 integrins and cytokeratin 15 was noted. At the cellular level, there was loss of beta4 integrin immunolocalization and random distribution of laminin-332 in Kindler syndrome keratinocytes. Of note, active beta1 integrin was reduced but overexpression of fermitin family homolog-1 restored integrin activation and partially rescued the Kindler syndrome cellular phenotype. This study provides evidence that fermitin family homolog-1 is implicated in integrin activation and demonstrates that lack of this protein leads to pathological changes beyond focal adhesions, with disruption of several hemidesmosomal components and reduced expression of keratinocyte stem cell markers. These findings collectively provide novel data on the role of fermitin family homolog-1 in skin and further insight into the pathophysiology of Kindler syndrome.

Waardenburg syndrome is a rare genetic disorder, inherited as an autosomal dominant trait. The condition is characterized by sensorineural hearing loss and pigment disturbances of the hair, skin, and iris. The de novo mutation in the SOX10 gene, responsible for Waardenburg syndrome type II, is rarely seen. The present study aimed to identify the genetic causes of Waardenburg syndrome type II in a Chinese family. Clinical and molecular evaluations were conducted in a Chinese family with Waardenburg syndrome type II. A novel SOX10 heterozygous c.259-260delCT mutation was identified. Heterozygosity was not observed in the parents and sister of the proband, indicating that the mutation has arisen de novo. The novel frameshift mutation, located in exon 3 of the SOX10 gene, disrupted normal amino acid coding from Leu87, leading to premature termination at nucleotide 396 (TGA). The high mobility group domain of SOX10 was inferred to be partially impaired. The novel heterozygous c.259-260delCT mutation in the SOX10 gene was considered to be the cause of Waardenburg syndrome in the proband. The clinical and genetic characterization of this family would help elucidate the genetic heterogeneity of SOX10 in Waardenburg syndrome type II. Moreover, the de novo pattern expanded the mutation data of SOX10. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

2017-01-01

Gingival fibromatosis with hypertrichosis syndrome is an extremely rare genetic condition characterized by profound overgrowth of hair and gums, as well as other variable features. Gingival fibromatosis is characterized by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. They were found to have a genetic origin, may also occur in isolation or be part of a syndrome, or acquired origin, due to specific drugs administered systemically. Congenital generalized hypertrichosis is a heterogeneous group of diseases with continuing excessive growth of terminal hair without androgenic stimulation. It has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. Various syndromes have been associated with these features such as epilepsy, mental retardation, cardiomegaly, or osteochondrodysplasia. As so far very few cases have been reported in literature, we are reporting a series of three cases with management of the same. The excess gingival tissues, in these cases, were removed by conventional gingivectomy under general anesthesia. The postoperative result was uneventful and the patient's appearance improved significantly. Good esthetic result was achieved to allow patient to practice oral hygiene measures. Though this is not a serious condition clinically, psychosocial trauma cannot be neglected owing to the cosmetic disfigurement it produces.

Pisa syndrome was first described in 1972 in patients treated with neuroleptics. Since 2003, when it was first reported in patients with Parkinson's disease (PD), Pisa syndrome has progressively drawn the attention of clinicians and researchers. Although emerging evidence has partially clarified its prevalence and pathophysiology, the current debate revolves around diagnostic criteria and assessment and the effectiveness of pharmacological, surgical, and rehabilitative approaches. Contrary to initial thought, Pisa syndrome is common among PD patients, with an estimated prevalence of 8.8% according to a large survey. Furthermore, it is associated with the following specific patient features: more severe motor phenotype, ongoing combined pharmacological treatment with levodopa and dopamine agonists, gait disorders, and such comorbidities as osteoporosis and arthrosis. The present literature on treatment outcomes is scant, and the uneven effectiveness of specific treatments has produced conflicting results. This might be because of the limited knowledge of Pisa syndrome pathophysiology and its variable clinical presentation, which further complicates designing randomized clinical trials on this condition. However, because some forms of Pisa syndrome are potentially reversible, there is growing consensus on the importance of its early recognition and the importance of pharmacological adjustment and rehabilitation. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

The Prothrombotic Tendency in Metabolic Syndrome: Focus on the Potential Mechanisms Involved in Impaired Haemostasis and Fibrinolytic Balance

PubMed Central

Russo, Isabella

2012-01-01

The metabolic syndrome is a clinical disorder characterized by impairment of glucose metabolism, increased arterial blood pressure, and abdominal obesity. The presence of these clinical features exposes patients to a high risk of atherothrombotic cardiovascular events. The pathogenesis of atherothrombosis in the metabolic syndrome is multifactorial, requiring a close relationship among the main components of the metabolic syndrome, including insulin resistance, alterations of glycaemic and lipid pattern, haemodynamic impairment, and early appearance of endothelial dysfunction. Furthermore, haemostatic alterations involving coagulation balance, fibrinolysis, and platelet function play a relevant role both in the progression of the arterial wall damage and in acute vascular events. The mechanisms linking abdominal obesity with prothrombotic changes in the metabolic syndrome have been identified and partially elucidated on the basis of alterations of each haemostatic variable and defined through the evidence of peculiar dysfunctions in the endocrine activity of adipose tissue responsible of vascular impairment, prothrombotic tendency, and low-grade chronic inflammation. This paper will focus on the direct role of adipose tissue on prothrombotic tendency in patients affected by metabolic syndrome, with adipocytes being able to produce and/or release cytokines and adipokines which deeply influence haemostatic/fibrinolytic balance, platelet function, and proinflammatory state.

The SAPHO syndrome represents a variety of clinically similar disorders with the key features of hyperostotic bone lesions in combination with chronic pustular skin disease. The respective pathophysiology of bone and joint manifestations in SAPHO syndrome is still a matter of discussion. For example it does not appear to represent reactive arthritis and HLA B27 antigen, with the latter being typically present in patients with spondyloarthopathies. Treatment of SAPHO syndrome is also not well established and consists of various antiinflammatory and antirheumatic drugs. Here, we report a female patient with active SAPHO syndrome suffering from sternal swelling of unknown origin that had been known for 10 years and a 4-year-history of severe lower back pain. Remarkable were also a typical pustulous palmar erythema associated with swelling and decreased motility of both MCP-I joints. Inflammation parameters were high with an ESR 68 mm/1st hour and a CRP of 19.6 mg/l. She was initially treated with rofecoxib and doxycycline, followed by sulfasalazine with only partial clinical response. Thereafter, both articular symptoms as well as cutaneous lesions responded well to a combination therapy with methotrexate and sulfasalazine. Thus, the case illustrates nicely that methotrexate in combination with another DMARD can be successfully applied to patients with long-term active SAPHO syndrome. PMID:19471601

Idiopathic nephrotic syndrome is the most common glomerular disease in childhood, affecting 1 to 3 per 100,000 children under the age of 16. It most commonly occurs in ages between 2 and 10. Its cause is unknown, and its histology corresponds to minimal change disease in 90% of cases, or focal segmental glomerulosclerosis. Steroid-resistant nephrotic syndrome represents 10-20% of idiopathic nephrotic syndrome in pediatrics. It has a poor prognosis, and its management is a significant therapeutic challenge. Half of patients evolve to end-stage renal disease within 5 years, and are additionally exposed to complications secondary to persistent NS and to the adverse effects of immunosuppressive therapy. The primary goal of treatment is to achieve complete remission, but even a partial remission is associated with a better renal survival than the lack of response. This paper is the result of the collaborative effort of the Nephrology Branch of the Chilean Society of Pediatrics with aims at helping pediatricians and pediatric nephrologists to treat pediatric idiopathic nephrotic syndrome. In this second part, handling of steroid-resistant nephrotic syndrome as well as nonspecific therapies are discussed. Copyright © 2015 Sociedad Chilena de Pediatría.

2012-04-01

Lacosamide is a new antiepileptic drug that is currently approved by the US Food and Drug Administration (FDA) for adults 17 years or older for partial-onset seizures. The authors reviewed 21 pediatric patients (<17 years) with various seizure types who were started on oral lacosamide as part of a prospective add-on study as adjunctive therapy for refractory epilepsy. Five patients were excluded due to less than 3 months of meaningful follow-up. Maintenance dosages used ranged from 2.4 to 19.4 mg/kg/d. Eight of 16 (50%) patients had greater than 50% reduction in seizure frequency with adjunctive lacosamide therapy. Eight (50%) patients had generalized epilepsy including 4 with Lennox-Gastaut syndrome. Lacosamide was effective therapy for most seizure types but was particularly effective for partial-onset seizures. Lacosamide was effective in treating 5 of 8 (62.5%) localization-related epilepsies but only 2 of 8 (25%) generalized epilepsies, both Lennox-Gastaut syndrome patients with greater than 90% seizure reduction. None of these very refractory patients remained seizure free.

Seizure drawings: insight into the self-image of children with epilepsy.

Epilepsy is a chronic disorder that is associated with numerous psychological challenges, especially in children. Drawings have been underutilized as a method to obtain insight into psychological issues in children with epilepsy. We asked 105 children with epilepsy, ages 5 to 18 years, to draw a picture of what it is like to have a seizure. Across ages and epilepsy syndromes, the drawings showed evidence of impaired self-concept, low self-esteem, and a sense of helplessness and vulnerability. Overall, the drawings of human figures were less developed than expected for chronological age. In some drawings, indicators of underlying depression were found. When considered by epilepsy syndrome or seizure type, some specific artistic features were noted. Children with simple partial (motor) seizures drew distorted body parts, especially limbs. Those with complex partial seizures depicted sensory symptoms and mental status changes such as confusion. Children with generalized tonic-clonic seizures showed shaking extremities. Drawings by children with absence seizures illustrated mainly staring. In conclusion, drawings are a powerful method to examine the self-concept of children with epilepsy and gain insight into their feelings about themselves and their world.

To study and assess clinical outcomes of various modes of treatment for perforated giant gastric ulcer in an emergency setting. From May 2010 to February 2013, 20 cases of perforated giant gastric ulcer (> 2 cm) were operated on in an emergency setting. All the patients presented with features of peritonitis and were resuscitated aggressively before taking for surgery. In the first 4 cases, primary closure was done after taking a biopsy and among these, the 3(rd) case also underwent partial distal gastrectomy and gastrojejunostomy and the 4(th) case underwent a radical subtotal gastrectomy with D2 lymphadenectomy and gastrojejunostomy for malignancy. All the remaining 16 cases underwent partial distal gastrectomy and gastrojejunostomy. Among the first 4 cases, 2 had an uneventful recovery and were discharged on the 6(th) postoperative day. The 3(rd) and 4(th) patients developed gastric fistula, leading to prolonged hospitalization. For the 3(rd) patient, conservative management was tried for 1 wk, followed by partial distal gastrectomy and gastrojejunostomy, and he was discharged on the 20(th) day after admission, while the 4(th) patient underwent a radical subtotal gastrectomy with D2 lymphadenectomy and gastrojejunostomy. Postoperatively, he developed adult respiratory distress syndrome, multiorgan dysfunction syndrome and expired on the 3(rd) postoperative day of the second surgery. All the remaining 16 patients underwent partial distal gastrectomy and gastrojejunostomy and recovered well. Among these, 4 of them were malignant and the remaining were benign ulcers. All had an uneventful recovery. The percentage of malignancy in our series was 30% (6 out of 20 cases). In our study, 86% had an uneventful recovery, complications were seen in about 10%, and mortality was about 5%. In giant gastric ulcer, the chances of malignancy and leak after primary closure are high. So, we feel that partial distal gastrectomy and gastrojejunostomy is better.

To provide quantitative information about the facial soft tissue of Italian and Northern Sudanese subjects with Down syndrome by using summary anthropometric measurements. The three-dimensional coordinates of soft tissue facial landmarks were obtained using a computerized digitizer in 54 Italian subjects with Down syndrome (20 females and 34 males, 13 to 52 years), in 64 Northern Sudanese subjects with Down syndrome (18 females and 46 males, 5 to 34 years), and in 578 Italian and 653 Northern Sudanese reference subjects, matched for sex and age. From the landmarks, 16 facial dimensions were calculated. Data from subjects with Down syndrome were compared with those collected from control individuals by computing z scores. Two summary anthropometric measurements for quantifying craniofacial variations were obtained: the mean z score (an index of overall facial size) and its standard deviation, the craniofacial variability index (an index of facial harmony). In subjects with Down syndrome, facial size was significantly smaller and craniofacial variability was significantly greater than in typically developed individuals; 93% of Italian and 81% of Northern Sudanese subjects with Down syndrome had one or both values outside the normal interval. Overall, Italian subjects with Down syndrome differed more from the norm than did those from Northern Sudan. In the Northern Sudanese subjects, the mean z scores and the craniofacial variability index were significantly influenced by age: Older Northern Sudanese subjects with Down syndrome had smaller mean z scores and craniofacial variability index values than younger subjects. The two ethnic groups had different alterations in their soft tissue facial dimensions that were partially influenced by age.

The purpose of this study is to evaluate the lateral rectus periosteal fixation and partial vertical rectus transpositioning (VRT) as treatment modalities to correct exotropic Duane retraction syndrome (Exo-DRS). Prospective interventional case study of cases of Exo-DRS with limitation of adduction. A total of 13 patients were subdivided into two groups. Six patients underwent only lateral rectus periosteal fixation (group A) and seven patients also underwent partial VRT (group B). Assessment involved prism bar cover test, abduction and adduction range, extent of binocular single visual field and exophthalmometry. These tests were repeated at 1 week, 1 month and 3 months post-operatively and data analyzed. The pre-operative mean values and ranges were 26.2 Δ (22-35) exotropia for group A and -21.3 Δ (14-30) exotropia for group B. The post-operative mean and range was +0.6 Δ esotropia (+20 to -8) for group A and 8 Δ (-2 to -20) exotropia for group B. Mean grade of limitation of abduction changed from -3.8 to -3.6 versus -3.6 to -2.8 and mean grade of limitation of adduction changed from -1.9 to -0.7 versus -1.5 to -0.5 in the groups A and B respectively. Mean binocular single visual field changed from 14.7° to 23.3° in group A and 11.8° to 26.4° in the group B respectively. Lateral rectus periosteal fixation is an effective surgery to correct the exodeviation, anomalous head posture and improving adduction in Exo-DRS and partial VRT in addition is effective in improving abduction and binocular single visual fields.

Study Objectives: Chronic partial sleep loss is associated with obesity and metabolic syndrome in humans. We used rats with lesions in the ventrolateral preoptic area (VLPO), which spontaneously sleep about 30% less than intact rats, as an animal model to study the consequences of chronic partial sleep loss on energy metabolism. Participants: Adult male Sprague-Dawley rats (300-365 g). Interventions: We ablated the VLPO in rats using orexin-B-saporin and instrumented them with electrodes for sleep recordings. We monitored their food intake and body weight for the next 60 days and assessed their sleep-wake by 24-h EEG/EMG recordings on day 20 and day 50 post-surgery. On day 60, after blood samples were collected for metabolic profiling, the animals were euthanized and the brains were harvested for histological confirmation of the lesion site. Measurements and Results: VLPO-lesioned animals slept up to 40% less than sham-lesioned rats. However, they showed slower weight gain than sham-lesioned controls, despite having normal food intake. An increase in plasma ghrelin and a decrease in leptin levels were observed, whereas plasma insulin levels remained unaffected. As expected from leaner animals, plasma levels of glucose, cholesterol, triglycerides, and C-reactive protein were reduced in VLPO-lesioned animals. Conclusions: Chronic partial sleep loss did not lead to obesity or metabolic syndrome in rats. This finding raises the question whether adverse metabolic outcomes associated with chronic partial sleep loss in humans may be due to factors other than short sleep, such as circadian disruption, inactivity, or diet during the additional waking hours.

2018-06-07

Prader⁻Willi syndrome (PWS) is a complex genetic disorder that, besides cognitive impairments, is characterized by hyperphagia, obesity, hypogonadism, and growth impairment. Proprotein convertase subtilisin/kexin type 1 ( PCSK1 ) deficiency, a rare recessive congenital disorder, partially overlaps phenotypically with PWS, but both genetic disorders show clear dissimilarities as well. The recent observation that PCSK1 is downregulated in a model of human PWS suggests that overlapping pathways are affected. In this review we will not only discuss the mechanisms by which PWS and PCSK1 deficiency could lead to hyperphagia but also the therapeutic interventions to treat obesity in both genetic disorders.

Regression of stroke-like lesions in MELAS-syndrome after seizure control.

There are some indications that seizure activity promotes the development of stroke-like episodes, or vice versa, in patients with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome or other syndromic mitochondrial disorders. A 41-year-old Caucasian female with MELAS syndrome, presenting with short stature, microcytic anaemia, increased blood-sedimentation rate, myopathy, hyper-gammaglobulinaemia, an iron-metabolism defect, migraine-like headaches, and stroke-like episodes, developed complex partial and generalised seizures at age 32 years. Valproic acid was ineffective but after switching to lamotrigine and lorazepam, she became seizure-free for five years and stroke-like episodes did not recur. Cerebral MRI initially showed enhanced gyral thickening and a non-enhanced T2-hyperintensity over the left parieto-temporo-occipital white matter and cortex and enhanced caudate heads. After two years without seizures, the non-enhanced hyperintense parieto-temporo-occipital lesion had disappeared, being attributed to consequent seizure control. The caudate heads, however, remained hyperintense throughout the observational period. This case indicates that adequate seizure control in a patient with MELAS syndrome may prevent the recurrence of stroke-like episodes and may result in the disappearance of stroke-like lesions on MRI.

Cloning, genomic organization, and chromosomal localization of human citrate transport protein to the DiGeorge/velocardiofacial syndrome minimal critical region

DiGeorge syndrome (DGS) and velocardiofacial syndrome have been shown to be associated with microdeletions of chromosomal region 22q11. More recently, patients with conotruncal anomaly face syndrome and some nonsyndromic patients with isolated forms of conotruncal cardiac defects have been found to have 22q11 microdeletions as well. The commonly deleted region, called the DiGeorge chromosomal region (DGCR), spans approximately 1.2 mb and is estimated to contain at least 30 genes. We report a computational approach for gene identification that makes use of large-scale sequencing of cosmids from a contig spanning the DGCR. Using this methodology, we have mapped the human homologmore » of a rodent citrate transport protein to the DGCR. We have isolated a partial cDNA containing the complete open reading frame and have determined the genomic structure by comparing the genomic sequence from the cosmid to the sequence of the cDNA clone. Whether the citrate transport protein can be implicated in the biological etiology of DGS or other 22q11 microdeletion syndromes remains to be defined. 36 refs., 3 figs., 1 tab.« less

The role of psychosocial stress in the development of obesity and metabolic syndrome is receiving increased attention and has led to examination of whether physical activity may moderate the stress-metabolic syndrome relationship. The current study examined relationships among physical activity, stress, and metabolic syndrome in adolescents. Participants (N = 126; 57 girls, 69 boys) were assessed for anthropometry, psychosocial stress, physical activity, and metabolic syndrome variables; t tests were used to examine sex differences, and regression analysis was used to assess relationships among variables controlling for sex and maturity status. Mean body mass index approached the 75th percentile for both sexes. Typical sex differences were observed for systolic blood pressure, time spent in moderate and vigorous physical activity, and perceived stress. Although stress was not associated with MetS (β = -.001, P = .82), a modest, positive relationship was observed with BMI (β = .20, P = .04). Strong relationships between physical activity and stress with MetS or BMI were not found in this sample. Results may be partially explained by overall good physical health status of the participants. Additional research in groups exhibiting varying degrees of health is needed.

Effect of oxandrolone therapy on adult height in Turner syndrome patients treated with growth hormone: a meta-analysis.

Turner syndrome is a chromosomal abnormality in which there is complete or partial absence of the X chromosome. Turner syndrome effects 1 in every 2000 live births. Short stature is a cardinal feature of Turner Syndrome and the standard treatment is recombinant human growth hormone. When growth hormone is started at an early age a normal adult height can be achieved. With delayed diagnosis young women with Turner Syndrome may not reach a normal height. Adjuvant therapy with oxandrolone is used but there is no consensus on the optimal timing of treatment, the duration of treatment and the long term adverse effects of treatment. The objective of this review and meta-analysis is to examine the effect of oxandrolone on adult height in growth hormone treated Turner syndrome patients. Eligible trials were identified by a literature search using the terms: Turner syndrome, oxandrolone. The search was limited to English language randomized-controlled trials after 1980. Twenty-six articles were reviewed and four were included in the meta-analysis. A random effects model was used to calculate an effect size and confidence interval. The pooled effect size of 2.0759 (95 % CI 0.0988 to 4.0529) indicates that oxandrolone has a positive effect on adult height in Turner syndrome when combined with growth hormone therapy. In conclusion, the addition of oxandrolone to growth hormone therapy for treatment of short stature in Turner syndrome improves adult height. Further studies are warranted to investigate if there is a subset of Turner syndrome patients that would benefit most from growth hormone plus oxandrolone therapy, and to determine the optimal timing and duration of such therapy.

Neuropsychological findings associated with Panayiotopoulos syndrome in three children.

2016-01-01

Panayiotopoulos syndrome is a common idiopathic benign epilepsy that has a peak age of onset in early childhood. The syndrome is multifocal and shows significant electroencephalogram (EEG) variability, with occipital predominance. Although a benign syndrome often refers to the absence of neurological and neuropsychological deficits, the syndrome has recently been associated with cognitive impairments. Also, despite frequent occipital EEG abnormalities, research regarding the visual functioning of patients is less reported and often contradictory. The purpose of this study was to gain additional knowledge regarding the neurocognitive functioning of patients with Panayiotopoulos syndrome and specifically to address any visual processing deficits associated with the syndrome. Following diagnosis of the syndrome based on typical clinical and electrophysiological criteria, three patients, aged 5, 8, and 10years were referred by epileptologists for neuropsychological evaluation. Neuropsychological findings suggest that the patients had notable impairments on visual memory tasks, especially in comparison with verbal memory. Further, they demonstrated increased difficulty on picture memory suggesting difficulty retaining information from a crowded visual field. Two of the three patients showed weakness in visual processing speed, which may account for weaker retention of complex visual stimuli. Abilities involving attention were normal for all patients, suggesting that inattention is not responsible for these visual deficits. Academically, the patients were weak in numerical operations and spelling, which both rely partially on visual memory and may affect achievement in these areas. Overall, the results suggest that patients with Panayiotopoulos syndrome may have visual processing and visual memory problems that could potentially affect their academic capabilities. Identifying such difficulties may be helpful in creating educational and remedial assistance programs for children with this syndrome, as well as developing appropriate presentation of information to these children in school.

Identification of single-gene causes of steroid-resistant nephrotic syndrome (SRNS) has furthered the understanding of the pathogenesis of this disease. Here, using a combination of homozygosity mapping and whole human exome resequencing, we identified mutations in the aarF domain containing kinase 4 (ADCK4) gene in 15 individuals with SRNS from 8 unrelated families. ADCK4 was highly similar to ADCK3, which has been shown to participate in coenzyme Q10 (CoQ10) biosynthesis. Mutations in ADCK4 resulted in reduced CoQ10 levels and reduced mitochondrial respiratory enzyme activity in cells isolated from individuals with SRNS and transformed lymphoblasts. Knockdown of adck4 in zebrafish and Drosophila recapitulated nephrotic syndrome-associated phenotypes. Furthermore, ADCK4 was expressed in glomerular podocytes and partially localized to podocyte mitochondria and foot processes in rat kidneys and cultured human podocytes. In human podocytes, ADCK4 interacted with members of the CoQ10 biosynthesis pathway, including COQ6, which has been linked with SRNS and COQ7. Knockdown of ADCK4 in podocytes resulted in decreased migration, which was reversed by CoQ10 addition. Interestingly, a patient with SRNS with a homozygous ADCK4 frameshift mutation had partial remission following CoQ10 treatment. These data indicate that individuals with SRNS with mutations in ADCK4 or other genes that participate in CoQ10 biosynthesis may be treatable with CoQ10. PMID:24270420

Skull base metastases frequently appear in a late stage of various tumor entities and cause pain and neurological disorders which strongly impair patient quality of life. This study retrospectively analyzed fractionated external beam radiotherapy (EBRT) as a palliative treatment approach with special respect to neurological outcome, feasibility and acute toxicity. A total of 30 patients with skull base metastases and cranial nerve disorders underwent EBRT with a mean total dose of 31.6 Gy. Neurological status was assessed before radiotherapy, during radiotherapy and 2 weeks afterwards categorizing orbital, parasellar, middle fossa, jugular foramen and occipital condyle involvement and associated clinical syndromes. Neurological outcome was scored as persistence of symptoms, partial response, good response and complete remission. Treatment-related toxicity and overall survival were assessed. Before EBRT 37 skull base involvement syndromes were determined with 4 patients showing more than 1 syndrome. Of the patients 81.1 % responded to radiotherapy with 10.8 % in complete remission, 48.6 % with good response and 21.6 % with partial response. Grade 1 toxicity of the skin occurred in two patients and grade 1 hematological toxicity in 1 patient under concurrent chemoradiotherapy. Median overall survival was 3.9 months with a median follow-up of 45 months. The use of EBRT for skull base metastases with symptomatic involvement of cranial nerves is marked by good therapeutic success in terms of neurological outcome, high feasibility and low toxicity rates. These findings underline EBRT as the standard therapeutic approach in the palliative setting.

The most detailed reports of the response of the gastrointestinal system to high dose acute radiation have focused mainly on understanding the histopathology. However, to enable medical countermeasure assessment under the animal rule criteria, it is necessary to have a robust model in which the relationship between radiation dose and intestinal radiation syndrome incidence, timing and severity are established and correlated with histopathology. Although many mortality studies have been published, they have used a variety of mouse strains, ages, radiation sources and husbandry conditions, all of which influence the dose response. Further, it is clear that the level of bone marrow irradiation and supportive care can influence endpoints. In order to create robust baseline data we have generated dose response data in adult male mice, maintained under identical conditions, and exposed to either total or partial-body irradiation. Partial-body irradiation includes both extensive (40%) and minimal (5%) bone marrow sparing models, the latter designed to correlate with an established primate model and allow assessment of effects of any medical countermeasure on all three major radiation syndromes (intestinal, bone marrow and lung) in the surviving mice. Lethal dose (LD30, LD50 and LD70) data are described in the various models, along with the impact of enteric flora and response to supportive care. Correlation with diarrhea severity and histopathology are also described. This data can be used to aid the design of good laboratory practice (GLP) compliant Animal Rule studies that are reflective of the conditions following accidental radiation exposure. PMID:23091876

[Burnout: a useful diagnosis?].

PubMed

Thalhammer, Matthias; Paulitsch, Klaus

In psychiatry, burnout is a relevant phenomenon. A large number of individuals is feeling overburdened at work. In contrast to mental disorders, the term 'burnout' is not perceived as stigmatizing, making it therefore easier for afflicted persons to seek help. The term 'burnout syndrome' was mentioned 1974 for the first time in scientific literature. Today, there is a range of partially contradictory definitions and explanations for burnout and the burnout syndrome, respectively. In most studies, burnout is assessed by the Maslach Burnout Inventory, which is neither useful for determining the degree of pathology nor for distinguishing burnout from mental disorders such as depression. It is expected that the burnout syndrome will not be used in modern diagnostic classification systems, because of its unclear definition and conceptual contradictions. On these grounds, it appears reasonable to define burnout as long-term professional overload and a noteworthy risk factor for physical diseases and mental disorders.

The objective of this paper is to demonstrate that structural alterations of the nasal cavity, e.g. septal deviation and conchal hypertrophy have high incidence in patients with sleep apnea and hypopnea syndrome and must be addressed with associated specific procedures of the syndrome. Clinical retrospective. A retrospective study of 200 patients was performed, with 196 male and 4 female, attended at the otorhinolaryngology ambulatory of Hospital Prof. Edmundo Vasconcelos and Unidade Paulista de Otorrinolaringologia, all of them subjected to polysomnography, otorhinolaryngological physical exam, endoscopy exam, and surgical treatment with nasal and pharyngeal procedures. All of them were subjected to pharyngeal procedure: uvulopalatopharyngoplasty or uvulopalatoplasty and nose procedure: 176 septoplasty with partial turbinectomy (88%) and 24 isolated turbinectomy, with satisfactory results. We can see that structural alterations of the nasal cavity have high incidence in patients with OSA.

Sickle cell 'girdle syndrome' progressing to ischaemic colitis and colonic perforation.

Abdominal pain of presumed vasocclusive origin, often termed 'girdle syndrome' because of the circumferential distribution of the pain, is common in sickle cell anaemia (SCA). Evidence of progression to bowel infarction is rare. A 27-year-old man with SCA developed chest and abdominal pain unresponsive to opiate analgesia. Abdominal X-ray showed dilated bowel loops because of partial obstruction. Despite reduction of HbS to 23% by automated red cell exchange, abdominal pain worsened. A CT scan was the most informative investigation and showed free peritoneal air. He underwent emergency hemicolectomy and reversible ileostomy formation. Histology of the resected colon was consistent with acute ischaemic colitis. Early surgical intervention remains essential in SCA when abdominal pain does not respond to maximal therapy including red cell exchange: as this case illustrates, sickle girdle syndrome has the capacity to progress to irreversible ischaemic colitis and necrotic perforation of the bowel wall.

Trisomy 4p and deletion 4p- in a family having translocation, t(4p-; 12p+).

1978-01-01

Chromosome studies on a newborn infant with the clinical features of 4p-syndrome revealed a 46,XY,4p-karyotype with deletion of bands distal to 4p14. Investigation of the family revealed normal chromosomes in the mother and a balanced translocation rcp(4;12) (p14;p13) in the father, the paternal grandfather and an uncle. A severely retarded and malformed aunt is a partial trismoy for the short arms of chromosome 4, with the unbalanced karyotype 45,XX,12p+. It appears that monosomy of bands 4p15 and 4p16 leads to the full clinical features of 4p-syndrome, while trisomy of this region causes disabilities consistent with the rather more variable 4p trisomy syndrome. From currently reported cases, a summary is presented of the results of pregnancies of both male and female translocation carriers.

Anterior spinal artery syndrome. Paraplegia following segmental ischaemic injury to the spinal cord after oesophagectomy.

PubMed

Djurberg, H; Haddad, M

1995-04-01

A case of unexpected paraplegia after oesophageal resection under general anaesthesia combined with epidural analgesia and intra-operative intercostal block is described. Patients with compromised cardiovascular and respiratory function undergoing thoracic or major abdominal surgery can benefit significantly intra-operatively from a combination of general anaesthesia and regional analgesia. The continued use of regional analgesia into the postoperative period offers even more advantages. General anaesthesia administered before regional analgesia may, however, mask complications related to the regional technique and delay the instigation of corrective measures. The blood supply to the anterior part of the spinal cord, through the artery of Adamkiewicz, may be impaired intra-operatively leading to neurological sequelae known as the anterior spinal artery syndrome, characterised by loss of motor function with intact or partially intact sensory function. Patients at risk of developing the syndrome can be identified pre-operatively.

Artico, M; Stevanato, G; Ionta, B; Cesaroni, A; Bianchi, E; Morselli, C; Grippaudo, F R

2012-06-01

The lower limbs are frequently involved in neurovascular compression syndromes, owing to their anatomical, vascular and muscular characteristics and to the orthostatic position. These syndromes were identified by exclusion, using neuroimaging techniques and treated by microsurgical techniques. Eight patients with a neurovascular compression syndrome due to venous vascular lesions in the lower limbs (popliteal fossa, proximal and medial third of the inferior limb, tarsal tunnel) were selected. The symptomatology was characterized by pain, Tinel's sign, hyperalgesia, allodynia, numbness along the nerve course and foot weakness: all were exacerbated by the standing position, thus suggesting a neurovascular compression syndrome. Diagnostic tools comprised Doppler ultrasonography, Electromyography, CT 3D and MRI. Treatment consisted of microsurgery with neurovascular dissection. Following surgical treatment, rapid pain relief and a partial recovery of neurological deficits (including the ability to walk) was observed within 8-10 months. An early diagnosis of NCS using various neuroimaging techniques and prompt treatment may improve the response to surgical therapy. The aim of the case studies described is to improve understanding of these pathologies thus enabling correct clinical decisions.

Minocycline prevents cholinergic loss in a mouse model of Down's syndrome.

PubMed

Hunter, Christopher L; Bachman, David; Granholm, Ann-Charlotte

2004-11-01

Individuals with Down's syndrome develop Alzheimer's-like pathologies comparatively early in life, including progressive degeneration of basal forebrain cholinergic neurons (BFCNs). Cholinergic hypofunction contributes to dementia-related cognitive decline and remains a target of therapeutic intervention for Alzheimer's disease. In light of this, partial trisomy 16 (Ts65Dn) mice have been developed to provide an animal model of Down's syndrome that exhibits progressive loss of BFCNs and cognitive ability. Another feature common to both Down's syndrome and Alzheimer's disease is neuroinflammation, which may exacerbate neurodegeneration, including cholinergic loss. Minocycline is a semisynthetic tetracycline with antiinflammatory properties that has demonstrated neuroprotective properties in certain disease models. Consistent with a role for inflammatory processes in BFCN degeneration, we have shown previously that minocycline protects BFCNs and improves memory in mice with acute, immunotoxic BFCN lesions. We now report that minocycline treatment inhibits microglial activation, prevents progressive BFCN decline, and markedly improves performance of Ts65Dn mice on a working and reference memory task. Minocycline is an established antiinflammatory and neuroprotective drug and may provide a novel approach to treat specific AD-like pathologies.

Low Median Nerve Palsy as Initial Manifestation of Churg-Strauss Syndrome.

Anterior interosseous nerve (AIN) syndrome is typically characterized by forearm pain and partial or complete dysfunction of the AIN-innervated muscles. Although the exact etiology and pathophysiology of the disorder remain unclear, AIN syndrome is increasingly thought to be an inflammatory condition of the nerve rather than a compressive neuropathy because the symptoms often resolve spontaneously following prolonged observation. However, peripheral neuropathy can be 1 of the first symptoms of systemic vasculitis that needs early systemic immunotherapy to prevent extensive nerve damage. Churg-Strauss syndrome (CSS; eosinophilic granulomatosis with polyangiitis) is 1 type of primary systemic vasculitis that frequently damages the peripheral nervous system. CSS-associated neuropathy usually involves nerves of the lower limb, and few studies have reported on the involvement of the upper limb alone. We report on a rare case of low median nerve palsy as the initial manifestation of CSS. The patient recovered well with early steroid treatment for primary systemic vasculitis.

A primer on pituitary injury for the obstetrician gynecologist: Simmond's disease, Sheehan's Syndrome, traumatic injury, Dahan's Syndrome, pituitary apoplexy and lymphocytic hypophysitis.

PubMed

Dahan, Michael H; Tan, Seang L

2017-04-01

The pituitary gland plays a critical role in reproduction. In response to the hypothalamus the anterior pituitary secretes prolactin, thyroid-stimulating hormone, adreno-corticotropic hormone, follicle-stimulating hormone, luteinizing hormone and growth hormone. Dysregulation in these hormones often lead to reproductive failure. Multiple mechanisms of pituitary injury exist. Simmond's disease is atrophy or destruction of the anterior lobe of the pituitary gland resulting in hypopituitarism. Sheehan's syndrome is post-partum pituitary injury due to massive hemorrhage. Traumatic injury resulting in hemorrhage in a non-pregnancy state can also cause partial or complete pituitary failure. Dahan's syndrome is pituitary injury due to severe vasospasm, without significant hemorrhage. Pituitary apoplexy is infarction of a pituitary adenoma and intra-mass hemorrhage with result injury to hormone production by the gland. Lymphocytic infiltration is the most common cause of hypophysitis and the mechanism is often unknown, although it may be autoimmune-related. The mechanism and treatments of each of these pathologies will be discussed in a context of reproduction.

Usher syndrome (USH) is the most common genetic disease that causes both deafness and blindness. USH is divided into three types, USH1, USH2 and USH3, depending on the age of onset, the course of the disease, and on the degree of vestibular dysfunction. By homozygosity mapping of a consanguineous Danish family of Dutch descent, we have identified a novel locus for a rare USH3-like syndrome. The affected family members have a unique association of retinitis pigmentosa, progressive hearing impairment, vestibular dysfunction, and congenital cataract. The phenotype is similar, but not identical to that of USH3 patients, as congenital cataract has not been reported for USH3. By homozygosity mapping, we identified a 7.3 Mb locus on chromosome 15q22.2-23 with a maximum multipoint LOD score of 2.0. The locus partially overlaps with the USH1 locus, USH1H, a novel unnamed USH2 locus, and the non-syndromic deafness locus DFNB48. © 2010 John Wiley & Sons A/S.

Sjögren's syndrome (SS) and systemic lupus erythematosus (SLE) are related by clinical and serologic manifestations as well as genetic risks. Both diseases are more commonly found in women than in men, at a ratio of ~10 to 1. Common X chromosome aneuploidies, 47,XXY and 47,XXX, are enriched among men and women, respectively, in either disease, suggesting a dose effect on the X chromosome. We examined cohorts of SS and SLE patients by constructing intensity plots of X chromosome single-nucleotide polymorphism alleles, along with determining the karyotype of selected patients. Among ~2,500 women with SLE, we found 3 patients with a triple mosaic, consisting of 45,X/46,XX/47,XXX. Among ~2,100 women with SS, 1 patient had 45,X/46,XX/47,XXX, with a triplication of the distal p arm of the X chromosome in the 47,XXX cells. Neither the triple mosaic nor the partial triplication was found among the controls. In another SS cohort, we found a mother/daughter pair with partial triplication of this same region of the X chromosome. The triple mosaic occurs in ~1 in 25,000-50,000 live female births, while partial triplications are even rarer. Very rare X chromosome abnormalities are present among patients with either SS or SLE and may inform the location of a gene(s) that mediates an X dose effect, as well as critical cell types in which such an effect is operative. © 2017, American College of Rheumatology.

The purpose of this study was to determine if chronic fatigue syndrome (CFS) is associated with reduced blood flow and muscle oxidative metabolism. Patients with CFS according to CDC criteria (n=19) were compared to normal sedentary subjects (n = 11). Muscle blood flow was measured in the femoral artery with Doppler ultrasound after exercise. Muscle metabolism was measured in the medial gastrocnemius muscle using 31P magnetic resonance spectroscopy (MRS). Muscle oxygen saturation and blood volume were measured using near-infrared spectroscopy. CFS and controls were not different in hyperemic blood flow or phosphocreatine recovery rate. Cuff pressures of 50,60,70,80,and 90 mmHg were used to partially restrict blood flow during recovery. All pressures reduced blood flow and oxidative metabolism, with 90 mmHg reducing blood flow by 46% and oxidative metabolism by 30.7% in CFS patients. Hyperemic blood flow during partial cuff occlusion was significantly reduced in CFS patients (P < 0.01), and recovery of oxygen saturation was slower (P < 0.05). No differences were seen in the amount of reduction in metabolism with partially reduced blood flow. In conclusion, CFS patients showed evidence of reduced hyperemic flow and reduced oxygen delivery, but no evidence that this impaired muscle metabolism. Thus, CFS patients might have altered control of blood flow, but this is unlikely to influence muscle metabolism. Further, abnormalities in muscle metabolism do not appear to be responsible for the CFS symptoms. PMID:14578362

Differential diagnosis and diagnostic flow chart of joint hypermobility syndrome/ehlers-danlos syndrome hypermobility type compared to other heritable connective tissue disorders.

Joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type (JHS/EDS-HT) is an evolving and protean disorder mostly recognized by generalized joint hypermobility and without a defined molecular basis. JHS/EDS-HT also presents with other connective tissue features affecting a variety of structures and organs, such as skin, eye, bone, and internal organs. However, most of these signs are present in variable combinations and severity in many other heritable connective tissue disorders. Accordingly, JHS/EDS-HT is an "exclusion" diagnosis which needs the absence of any consistent feature indicative of other partially overlapping connective tissue disorders. While both Villefranche and Brighton criteria include such an exclusion as a mandatory item, a systematic approach for reaching a stringent clinical diagnosis of JHS/EDS-HT is still lacking. The absence of a consensus on the diagnostic approach to JHS/EDS-HT concerning its clinical boundaries with similar conditions contribute to limit our actual understanding of the pathologic and molecular bases of this disorder. In this review, we revise the differential diagnosis of JHS/EDS-HT with those heritable connective tissue disorders which show a significant overlap with the former and mostly include EDS classic, vascular and kyphoscoliotic types, osteogenesis imperfecta, Marfan syndrome, Loeys-Dietz syndrome, arterial tortuosity syndrome, and lateral meningocele syndrome. A diagnostic flow chart is also offered with the attempt to support the less experienced clinician in stringently recognizing JHS/EDS-HT and stimulate the debate in the scientific community for both management and research purposes. © 2015 Wiley Periodicals, Inc.

Metabolic syndrome and chronic conditions are significant predictors of cognition; however, few studies have examined how they work together in predicting cognition in old age. Therefore, the present study examines whether a chronic condition mediates the association between metabolic syndrome and cognition. In addition, it discusses the moderating role of sex in the relationships between metabolic syndrome, chronic conditions and cognition. Secondary analysis was carried out of data from the Malaysian national survey that involved 2322 community residents aged 60 years or older in Peninsular Malaysia. Cognition was measured by the digit symbol substitution test. Metabolic syndrome was assessed by five biomarkers: triglyceride, fasting blood sugar, systolic blood pressure, cholesterol ratio and body mass index. Chronic conditions were assessed by self-reported medical history. The structural equation modeling technique was used to analyze the mediation and moderation tests. The number of chronic conditions partially mediated the association between metabolic syndrome and cognition. Men and women did not differ in the relationship between metabolic syndrome and cognition; however, the number of chronic conditions was found to be negatively associated with cognition in older women, but not in men. Metabolic syndrome might increase the likelihood of older adults to suffer from more chronic conditions; these responses might reduce their cognition. To prevent cognitive decline in old age, specific intervention to minimize the number of chronic conditions by reducing their vascular risk factors is warranted, especially among older women.

To classify the Lennox twin pairs according to modern epilepsy classifications, use the classic twin model to identify which epilepsy syndromes have an inherited component, search for evidence of syndrome-specific genes, and compare concordances from Lennox's series with a contemporary Australian series. Following review of Lennox's original files describing twins with seizures from 1934 through 1958, the International League Against Epilepsy classifications of seizures and epileptic syndromes were applied to 169 pairs. Monozygous (MZ) and dizygous (DZ) pairs were subdivided into epilepsy syndromes and casewise concordances estimated. The authors excluded 26 pairs, with 71 MZ and 72 DZ pairs remaining. Seizure analysis demonstrated strong parallels between contemporary seizure classification and Lennox's terminology. Epilepsy syndrome diagnoses were made in 75%. The MZ and DZ casewise concordance estimates gave strong evidence for a major genetic influence in idiopathic generalized epilepsies (0.80 versus 0.00; n = 23). High MZ casewise concordances also supported a genetic etiology in symptomatic generalized epilepsies and febrile seizures. The pairs who were concordant for seizures usually had the same syndromic diagnoses in both twins (86% in MZ, 60% in DZ), suggesting syndrome-specific genes. Apart from partial epilepsies, the MZ casewise concordances were similar to those derived from Australian twin data. The authors were able to apply contemporary classifications to Lennox's twins. The data confirm genetic bases for common generalized epilepsies as well as febrile seizures and provide further support for syndrome-specific genes. Finally, comparable results to our Australian series were obtained, verifying the value of twin studies.

To assess the rates of incontinence and associated psychological problems in children, adolescents and adults with Down Syndrome, a genetic syndrome caused by partial or complete triplication (trisomy) of chromosome 21 and characterized by typical facial features, a physical growth delay and mild or moderate intellectual disability. Three hundred and seventeen persons with Down Syndrome (4-51 years) were recruited through a German parent support group (59.6% male, mean age 19.2 years). The Parental Questionnaire: Enuresis/Urinary Incontinence, the Incontinence Questionnaire-Pediatric Lower Urinary Tract Symptoms, as well as the Developmental Behavior Checklist (DBC) for parents or for adults were filled out by parents or care-givers. 17.2% of the sample had nocturnal enuresis, 15.9% had daytime urinary incontinence, and 14.2% had fecal incontinence. Incontinence was present in 64.0% of young children (4-12 years), 10.3% of teens (13-17 years), 12.8% of young adults (18-30 years) and in 22.4% of older adults (>30 years). 13.6% of children and 8.4% of adults had a DBC score in the clinical range. 19.5% of children and 27.8% of adults with incontinence had behavioral problems. There was a significant association between nocturnal enuresis, daytime urinary incontinence and clinical DBC scores in adults. Incontinence in Down Syndrome is mainly present in young children and increases in older adults. Behavioral comorbidity is associated with incontinence only in adults with Down Syndrome. Screening and treatment of incontinence in individuals with Down Syndrome is recommended. © 2016 Wiley Periodicals, Inc.

2018-02-01

Background The association between cardiorespiratory fitness, physical activity and coronary artery calcium (CAC) is unclear, and whether higher levels of fitness attenuate CAC prevalence in subjects with metabolic syndrome is not fully elucidated. The present study aims to: a) investigate the independent association of fitness on the prevalence of CAC, after adjustment for moderate-to-vigorous physical activity and sedentary time, and b) study the possible attenuation of increased CAC by higher fitness, in participants with metabolic syndrome. Design Cross-sectional. Methods In total 678 participants (52% women), 50-65 years old, from the SCAPIS pilot study were included. Fitness (VO 2 max) was estimated by submaximal cycle ergometer test and moderate-to-vigorous physical activity and sedentary time were assessed using hip-worn accelerometers. CAC score (CACS) was quantified using the Agatston score. Results The odds of having a significant CACS (≥100) was half in participants with moderate/high fitness compared with their low fitness counterparts. Further consideration of moderate-to-vigorous physical activity, sedentary time and number of components of the metabolic syndrome did only slightly alter the effect size. Those with metabolic syndrome had 47% higher odds for significant CAC compared with those without metabolic syndrome. However, moderate/high fitness seems to partially attenuate this risk, as further joint analysis indicated an increased odds for having significant CAC only in the unfit metabolic syndrome participants. Conclusions Being fit is associated with a reduced risk of having significant CAC in individuals with metabolic syndrome. While still very much underutilized, fitness should be taken into consideration in everyday clinical risk prediction in addition to the traditional risk factors of the metabolic syndrome.

Dyslipidaemia in nephrotic syndrome: mechanisms and treatment

Agrawal, Shipra; Zaritsky, Joshua J.; Fornoni, Alessia; Smoyer, William E.

2018-01-01

Nephrotic syndrome is a highly prevalent disease that is associated with high morbidity despite notable advances in its treatment. Many of the complications of nephrotic syndrome, including the increased risk of atherosclerosis and thromboembolism, can be linked to dysregulated lipid metabolism and dyslipidaemia. These abnormalities include elevated plasma levels of cholesterol, triglycerides and the apolipoprotein B containing lipoproteins VLDL and IDL; decreased lipoprotein lipase activity in the endothelium, muscle and adipose tissues; decreased hepatic lipase activity; and increased levels of the enzyme PCSK9. In addition, there is an increase in the plasma levels of immature HDL particles and reduced cholesterol efflux. Studies from the past few years have markedly improved our understanding of the molecular pathogenesis of nephrotic syndrome associated dyslipidaemia, and also heightened our awareness of the associated exacerbated risks of cardiovascular complications, progressive kidney disease and thromboembolism. Despite the absence of clear guidelines regarding treatment, various strategies are being increasingly utilized, including statins, bile acid sequestrants, fibrates, nicotinic acid and ezetimibe, as well as lipid apheresis, which seem to also induce partial or complete clinical remission of nephrotic syndrome in a substantial percentage of patients. Future potential treatments will likely also include inhibition of PCSK9 using recently developed anti PCSK9 monoclonal antibodies and small inhibitory RNAs, as well as targeting newly identified molecular regulators of lipid metabolism that are dysregulated in nephrotic syndrome.

Polycystic ovarian syndrome (PCOS) is the leading cause for anovulatory infertility. It is diagnosed by two of the following three clinical criteria: oligomenorrhoea, hyperandrogenism and polycystic appearance of the ovaries. Weight loss and physical activity can lead to ovulation and conception. Lowering of serum insulin normalizes androgen concentrations whereas ovulation induction often causes ovarian hyperstimulation. Theca cells from PCOS ovaries may be more responsive to insulin than cells from non-PCOS ovaries. Herein we review the research efforts at the genomic and cell function levels, as well as animal models, which have been made to elucidate the underlying mechanism that leads to PCOS. It appears that, despite the impressive amount of data that have been generated in these studies, the mechanism of this syndrome is still only partially understood. Polycystic ovarian syndrome (PCOS) is the leading cause for infertility, which is caused by anovulation. It is diagnosed by two of the following three clinical criteria: irregular and prolonged menstrual cycles, overt symptoms of excess androgens, which is revealed by acne and excess hair, and ultrasonographic appearance of the ovaries with multiple small follicles spread mainly near the ovarian surface, which gave it its name. Intentional weight loss and physical activity can lead to resumption of ovulation and not infrequently to conception as well. It was shown that lowering of serum insulin accounts for normalization of serum androgen levels, whereas ovulation induction with FSH often causes ovarian hyperstimulation. It is suggested that theca cells from PCOS ovaries may be more responsive to insulin than cells from non-PCOS ovaries. In this article we review the efforts to define the genes responsible for the syndrome and the studies at the cell function level, as well as animal models, which have been done to elucidate the underlying mechanism that leads to PCOS. Overall, it appears that despite the impressive amount of data that have been generated in these studies, the mechanism of this syndrome is still only partially understood.

We report the case of a 60-year-old Hispanic male with widespread necrotic purpuric lesions involving the penile, suprapubic, inguinal and hip dermis due to purpura fulminans. Purpura fulminans describes a rare syndrome involving intravascular thrombosis and hemorrhagic infarction of the skin; this rapidly progressing syndrome features vascular collapse and disseminated intravascular coagulation. This patient's penile necrosis involved the majority of the penile shaft and glans penis, and ultimately required partial glansectomy and repeated debridement for treatment. Subsequently, full thickness skin grafting was completed for reconstruction with good effect. While reports of penile necrosis secondary to various causes are documented in the literature, no prior reports describe penile necrosis secondary to purpura fulminans.

The blood cultures revealed a largely anaerobic sepsis with Fusobacterium necrophorum. This unusual pathogen is the most common cause of Lemierre's syndrome. A duplex sonogram and magnetic resonance imaging (MRI) of the neck region and vessels suggested a thrombophlebitis of the left internal jugular vein with partial occlusion, so that Lemierre's syndrome could be diagnosed. The patient was treated with appropriate antibiotics according to the resistogram and also with rivaroxaban.

Thyrotropinomas (TSHomas) are rare pituitary adenomas, particularly in childhood. We present here the case of an 11-year-old boy with type 1 autoimmune polyglandular syndrome (APS1) and TSHoma which was diagnosed by elevated thyroid - stimulating hormone and thyroid hormones levels without evident clinical signs of hyperthyroidism. He was underwent partial resection of the tumor via transsphenoidal approach and subsequently radiation therapy. Consequently, 1 year after radiotherapy, the patient developed growth hormone deficiency, three and half years after radiation became euthyroid, and five and half years after treatment - hypothyroid. This is the first case of the coexistence of these two rare endocrine diseases in one patient.

Turner syndrome (TS) is characterized by partial or complete loss of the second X-chromosome in phenotypic females resulting in a constellation of clinical findings that may include lymphedema, cardiac anomalies, short stature, primary ovarian failure and neurocognitive difficulties. Optimizing health care delivery is important to enable these individuals achieve their full potential. We review the current best practice management recommendations for individuals with TS focusing on the latest consensus opinion in regard to genetic diagnosis, treatment of short stature, estrogen supplementation, addressing psychosocial issues, as well screening for other comorbidities. A multidisciplinary approach and a well-planned transition to adult follow-up care will improve health care delivery significantly for this population. PMID:29344338

Sanfilippo Syndrome: Profound Deficiency of Alpha-Acetylglucosaminidase Activity in Organs and Skin Fibroblasts from Type-B Patients

Cultured skin fibroblasts from two patients with Sanfilippo syndrome, Type B were strikingly deficient in α-acetylglucosaminidase activity (α-2-acetamido-2-deoxy-D-glucoside acetamidodeoxyglucohydrolase, EC 3.2.1.X). A similar deficiency was found in frozen organs from two other patients. A partial deficiency of α-acetylglucosaminidase was found in cultured skin fibroblasts from both parents of one patient. Soluble endogenous inhibitors did not account for the enzyme deficiency. Other lysosomal hydrolases were normal or increased in cultured fibroblasts from patients with this disease. No deficiency of α-acetylglucosaminidase is present in other genetic mucopolysaccharidoses, including Sanfilippo Type A. PMID:4261742

PATHOPHYSIOLOGY, DIAGNOSIS AND TREATMENTOF DUMPING SYNDROME AND ITS RELATION TO BARIATRIC SURGERY.

PubMed

Chaves, Yasmin da Silva; Destefani, Afrânio Côgo

The dumping syndrome is frequent in bariatric surgery. It is probably the most common syndrome following partial or complete gastrectomy. Its prevalence in partial gastrectomy can reach up to 50%, thus it can be a significant complication arising from some types of bariatric surgeries. Critical analysis on dumping syndrome, its pathophysiology, diagnosis and treatment. A literature review was performed using the key words: 'dumping syndrome', 'bariatric surgery' and 'rapid dumping syndrome'. Inclusion criteria were: books, original works, case reports and meta-analyzes, and the exclusion criterion was literature review. Concerning the publication time, articles were screened between 1960 and May 2015. The dumping syndrome is complication arising from obesity surgeries, but also can be a result of vagus nerve damage. Diagnosis is done primarily through the use of questionnaires based on scores. The Sigstad score and Arts survey are valid means for assessing the dumping syndrome. Initial therapy consists in the adoption of dietary measures, short acting drugs administration. A síndrome de dumping é frequente após operações bariátricas. É, provavelmente, a mais comum das síndromes que sucedem gastrectomias parciais ou completas. Sua prevalência, em gastrectomias parciais pode chegar a até 50%, tornando-se assim complicação significante em alguns tipos de operações bariátricas. Realizar análise crítica sobre a síndrome de dumping em sua fisiopatologia, diagnóstico e tratamento. Foi realizada revisão bibliográfica utilizando os descritores: 'síndrome de dumping', 'cirurgia bariátrica' e 'síndrome do esvaziamento rápido'. Os critérios de inclusão foram: livros, trabalhos originais, relatos de caso e metanálises; excluíram-se as revisões bibliográficas. Quanto ao tempo de publicação, foram selecionados artigos entre 1960 e maio de 2015. A síndrome de dumping é complicação gastrointestinal oriunda de operações para obesidade, mas também pode ocasionar-se como consequência de danos no nervo vago. Seu diagnóstico é realizado primordialmente através da aplicação de questionários baseados em pontuações. O escore de Sigstad e questionário de Arts são meios válidos para avaliação da síndrome de dumping. A terapia inicial consiste na adoção de medidas dietéticas, ou fármacos administráveis de ação curta.

Fernández Pineda, Monica; Ramírez-Cheyne, Julián; Isaza, Carolina; Saldarriaga, Wilmar

The deletion of chromosomal region 1p36 is one of the most common sub-telomeric microdeletion syndromes and has distinctive dysmorphic features. On the other hand, partial trisomy of the short arm of chromosome 6 is a rare chromosomal abnormality with a variable phenotype. To report a case with both chromosome abnormalities, and to highlight the importance of the karyotype as a diagnostic tool in dysmorphology. The case of is presented of a two month-old infant with several craniofacial anomalies, neck haemangioma, sacral pit, rhizomelic shortening, small hands and feet, left unilateral cryptorchidism, and hypotonia. The infant also suffered intrauterine growth restriction and is the product of the eighth pregnancy of a 28 years old woman. Due to the unspecific findings in phenotype, a karyotype was requested, which showed a partial deletion of 1p36.1 and a partial trisomy of chromosome 6. The development of new techniques in molecular biology has improved diagnostic possibilities in medical genetics. However, the traditional karyotype remains as an important diagnostic tool in patients with multiple congenital anomalies. Copyright © 2016 Sociedad Chilena de Pediatría.

A substantial body of research has arisen concerning the relationships between objective residential area features, particularly area-level socioeconomic status and cardiometabolic outcomes. Little research has explored residents' perceptions of such features and how these might relate to cardiometabolic outcomes. Perceptions of environments are influenced by individual and societal factors, and may not correspond to objective reality. Understanding relations between environmental perceptions and health is important for the development of environment interventions. This study evaluated associations between perceptions of local built and social environmental attributes and metabolic syndrome, and tested whether walking behaviour mediated these associations. Individual-level data were drawn from a population-based biomedical cohort study of adults in Adelaide, South Australia (North West Adelaide Health Study). Participants' local-area perceptions were analysed in cross-sectional associations with metabolic syndrome using multilevel regression models (n = 1, 324). A nonparametric bootstrapping procedure evaluated whether walking mediated these associations. Metabolic syndrome was negatively associated with greater local land-use mix, positive aesthetics, and greater infrastructure for walking, and was positively associated with greater perceived crime and barriers to walking. Walking partially mediated associations between metabolic syndrome and perceived environmental features. Initiatives targeting residents' perceptions of local areas may enhance the utility of environmental interventions to improve population health.

Coenzyme Q(10) (CoQ) deficiency is an autosomal recessive disorder presenting five phenotypes: a myopathic form, a severe infantile neurological syndrome associated with nephritic syndrome, an ataxic variant, Leigh syndrome and a pure myopathic form. The third is the most common phenotype related with CoQ deficiency and it will be the focus of this review. This new syndrome presents muscle CoQ deficiency associated with cerebellar ataxia and cerebellar atrophy as the main neurological signs. Biochemically, the hallmark of CoQ deficiency syndrome is a decreased CoQ concentration in muscle and/or fibroblasts. There is no molecular evidence of the enzyme or gene involved in primary CoQ deficiencies associated with cerebellar ataxia, although recently a family has been reported with mutations at COQ2 gene who present a distinct phenotype. Patients with primary CoQ deficiency may benefit from CoQ supplementation, although the clinical response to this therapy varies even among patients with similar phenotypes. Some present an excellent response to CoQ while others show only a partial improvement of some symptoms and signs. CoQ deficiency is the mitochondrial encephalomyopathy with the best clinical response to CoQ supplementation, highlighting the importance of an early identification of this disorder.

Weight-loss diets with varying proportions of macronutrients have had varying effects on weight loss, and components of metabolic syndrome and risk factors for vascular diseases. However, little work has examined the effect of weight-neutral dietary changes in macronutrients on these factors. This is an investigation using the OMNI Heart datasets available from the NHLBI BioLINCC program. This study compared a DASH-like diet high in carbohydrates with similar diets high in protein and high in unsaturated fats. Measures of metabolic syndrome, except waist, and measures of risk factors for vascular diseases were taken at the end of each dietary period. All 3 diets significantly lowered the number of metabolic syndrome components (p ≤ 0.002) with a standardized measure of changes in metabolic syndrome components, suggesting that the high-protein, high-fat diet was most efficacious overall (p = 0.035). All 3 diets lowered a calculated 10-year risk of cardiovascular disease, with the high-protein and unsaturated fat diet being the most efficacious (p < 0.001). Only the unsaturated fat diet showed a slightly decreased calculated 9-year risk of diabetes (p = 0.11). Of the 3 weight-neutral diets, those high in protein and unsaturated fats appeared partially or wholly most beneficial.

The study aims to demonstrate the value of the 'tail sign' in the assessment of Dandy-Walker malformation. A total of 31 fetal magnetic resonance imaging (MRI), performed before 24 weeks of gestation after second-line ultrasound examination between May 2013 and September 2014, were examined retrospectively. All MRI examinations were performed using a 1.5 Tesla magnet without maternal sedation. Magnetic resonance imaging diagnosed 15/31 cases of Dandy-Walker malformation, 6/31 of vermian partial caudal agenesis, 2/31 of vermian hypoplasia, 4/31 of vermian malrotation, 2/31 of Walker-Warburg syndrome, 1/31 of Blake pouch cyst and 1/31 of rhombencephalosynapsis. All data were compared with fetopsy results, fetal MRI after the 30th week or postnatal MRI; the follow-up depended on the maternal decision to terminate or continue pregnancy. In our review study, we found the presence of the 'tail sign'; this sign was visible only in Dandy-Walker malformation and Walker-Warburg syndrome. The 'tail sign' could be helpful in the difficult differential diagnosis between Dandy-Walker, vermian malrotation, vermian hypoplasia and vermian partial agenesis. © 2015 John Wiley & Sons, Ltd.

We present the perinatal findings of a fetus with a de novo unbalanced chromosome translocation that resulted in monosomy for proximal 14q and monosomy for distal 4p. Prenatal sonographic examination at 27 weeks of gestation showed intrauterine growth retardation, microcephaly, cardiomegaly with arrhythmia, and asymmetry of the upper limbs. Genetic amniocentesis showed an abnormal karyotype of 45,XX,der(4)t(4;14)(p16.3;q12),-14. Linkage analysis of the family confirmed the maternal origin of the deletions. Molecular refinement of the deletion breakpoints indicated that the breakpoints at 4p16.3 and 14q12 were located between loci D4S403 (present) and D4S394 (absent), and between loci D14S252 (present) and D14S64 (absent), respectively. Necropsy showed dysmorphic features compatible with Wolf-Hirschhorn syndrome, hypertrophic cardiomyopathy, partial hemihypoplasia, and a normal brain without evidence of holoprosencephaly. Our case adds to the list of clinical phenotypes associated with the proximal regions of 14q.

Although tamoxifen has been shown to be fairly safe and effective for idiopathic pubertal gynecomastia, it remains unknown whether it is also beneficial for gynecomastia associated with endocrine disorders. Here, we report the effect of tamoxifen on pubertal gynecomastia in 2 siblings with partial androgen insensitivity syndrome (PAIS). Cases 1 and 2 presented with persistent pubertal gynecomastia at 13 and 16 years of age, respectively. Physical examinations revealed breast of Tanner stage 3 and normal male-type external genitalia in both cases. Clinical features such as female-type pubic hair and borderline small testis indicated mildly impaired masculinization. Molecular analysis identified a previously reported p.Arg789Ser mutation in the androgen receptor gene (AR) in the 2 cases. Two months of oral administration of tamoxifen ameliorated gynecomastia to Tanner stage 2 with no adverse events. Additional treatment with testosterone enanthate showed negligible effects on body hair and penile length. Hormone values of the 2 cases during tamoxifen treatment remained similar to those in previously reported untreated patients with PAIS. The results indicate that tamoxifen was effective in treating pubertal gynecomastia in these 2 patients with PAIS and may be considered as a therapeutic option in this situation pending further studies.

The theory of gastrointestinal duplication and enteric cyst embryogenesis was verified by examining the developmental process of this experimentally induced anomaly. In Cynopus pyrrhogaster (amphibian) embryos (stage 18), the dorsal midline structures (including the neural plate and notochord) were split regionally to induce partial separation of the notochord and gut anlage endoderm herniation between the split elements of the notochord. Following this procedure, the embryonic development was traced morphologically and histologically. Control embryos were cultured without the procedure. Following the incubation and breeding period, gastrointestinal duplication and enteric cysts were observed with vertebral anomaly, spina bifida, split cord malformation and subcutaneous manifestations in the mature animals. The combination of anomalies that was observed in these experimental animals is consistent with that found in "split notochord syndrome." No abnormal morphology or histology was observed in the control group. The embryogenetic theory of gastrointestinal duplication and enteric cysts was thus verified by simulating the partial separation of the notochord, which induced split notochord syndrome in laboratory animals. The results indicate that gastrointestinal duplication and enteric cysts may arise through a process of herniation of the gut anlage endoderm between split elements of the notochord.

Presently, the matter of pregnancy outcomes of patients with pregnancy related AKI (PR-AKI) were disputed. Thus, we conducted a meta-analysis to evaluate the impact of PR-AKI on pregnancy outcomes. We systematically searched MEDLINE, Embase, VIP, CNKI and Wanfang Databases for cohort or case-control studies in women with PR-AKI and those without AKI as a control group to assess the influence of PR-AKI on pregnancy outcomes and kidney outcome. Reduction of odd ratio (OR) was calculated by a random-effects model. One thousand one hundred fifty two articles were systematically reviewed, of those 11 studies were included, providing data of 845 pregnancies in 834 women with PR-AKI and 5387 pregnancies in 5334 women without AKI. In terms of maternal outcomes, women with PR-AKI had a greater likelihood of cesarean delivery (OR, 1.49; 95% confidence interval [CI], 1.37 to 1.61), hemorrhage (1.26; 1.02 to 1.56), HELLP syndrome (1.86; 1.41 to 2.46), placental abruption (3.13; 1.96 to 5.02), DIC (3.41; 2.00 to 5.84), maternal death (4.50; 2.73 to 7.43), but had a lower risk of eclampsia (0.53; 0.34 to 0.83). Women with PR-AKI also had a longer stay in ICU (weighted mean difference, 2.13 day [95% CI 1.43 to 2.83 day]) compared with those without PR-AKI. As for fetal outcomes, higher incidence of stillbirth/perinatal death (3.39, 2.76 to 4.18), lower mean gestational age at delivery (-0.70 week [95% CI -1.21 to -0.19 week]) and lower birth weight (-740 g [95% CI -1180 to 310 g]) were observed in women with PR-AKI. The occurrence of kidney outcome, defined as ESRD requiring dialysis, in women with PR-AKI was 2.4% (95% CI 1.3% to 4.2%). PR-AKI remains a grave complication and has been associated with increased maternal and fetal mortality.

L'hématome sous capsulaire du foie (HSCF) est une complication rare mais gravissime de la grossesse. Devant une symptomatologie clinique souvent non spécifique et un tableau biologique retardé, son diagnostic est basé essentiellement sur les moyens de l'imagerie (échographie, TDM, IRM). Son traitement est fonction de l'intégrité ou non de la capsule de Glisson. Nous rapportons les observations de 6 patientes, à travers une étude rétrospective s’étalant sur la période du Janvier 2005 à Octobre 2008, incluant tous les cas de preeclampsie colligés au service de gynécologie obstétrique du CHU Hassan II. Durant la période d’étude, L'incidence de l'hématome sous capsulaire de foie chez les patientes préeclamptiques admises durant la période d’étude est de 1,49 %. Aucune des patientes n'a benificié d'un suivi prénatal au sein de notre formation. La moyenne d’âge des patientes est de 37,6 ans avec des extrêmes allant de 33 à 45 ans. La gestité moyenne était de 4,8 avec une parité moyenne de 4,5.l'hematome sous capsulaire est survenu en post partum chez tous nos cas avec un délai moyen de 4 jours et des extrêmes allant de J0 et J10 du post partum .Toutes les patientes ont présenté un HELLP syndrome concomitant à la survenue de cette complication gravissime.Le diagnostic positif s'est basé sur les données échographiques dans 5 cas (hemoperitoine –HSCF).l’équipe a opté pour une abstention thérapeutique avec surveillance armée chez 2 cas et l'exploration chirurgicale a été indiquée chez quatre patientes en instabilité hemodynamique.Nous avons déploré deux cas de décès maternel.

To study the relationship between seizure-related factors, non-verbal intelligence, and socio-economic status (SES) in a population-based sample of children with epilepsy. The latest ILAE International classifications of epileptic seizures and syndromes were used to classify seizure types and epileptic syndromes in all 6-12 year old children (N=198) with epilepsy in Hordaland County, Norway. The children had neuropediatric and EEG examinations. Of the 198 patients, demographic characteristics were collected on 183 who participated in psychological studies including Raven matrices. 126 healthy controls underwent the same testing. Severe non-verbal problems (SNVP) were defined as a Raven score at or <10th percentile. Children with epilepsy were highly over-represented in the lowest Raven percentile group, whereas controls were highly over-represented in the higher percentile groups. SNVP were present in 43% of children with epilepsy and 3% of controls. These problems were especially common in children with remote symptomatic epilepsy aetiology, undetermined epilepsy syndromes, myoclonic seizures, early seizure debut, high seizure frequency and in children with polytherapy. Seizure-related characteristics that were not usually associated with SNVP were idiopathic epilepsies, localization related (LR) cryptogenic epilepsies, absence and simple partial seizures, and a late debut of epilepsy. Adjusting for socio-economic status factors did not significantly change results. In childhood epilepsy various seizure-related factors, but not SES factors, were associated with the presence or absence of SNVP. Such deficits may be especially common in children with remote symptomatic epilepsy aetiology and in complex and therapy resistant epilepsies. Low frequencies of SNVP may be found in children with idiopathic and LR cryptogenic epilepsy syndromes, simple partial or absence seizures and a late epilepsy debut. Our study contributes to an overall picture of cognitive function and its relation to central seizure characteristics in a childhood epilepsy population and can be useful for the follow-up team in developing therapy strategies that meet the individual needs of the child with epilepsy.

Diagnostic Accuracy of Copeptin in the Differential Diagnosis of the Polyuria-polydipsia Syndrome: A Prospective Multicenter Study.

The polyuria-polydipsia syndrome comprises primary polydipsia (PP) and central and nephrogenic diabetes insipidus (DI). Correctly discriminating these entities is mandatory, given that inadequate treatment causes serious complications. The diagnostic "gold standard" is the water deprivation test with assessment of arginine vasopressin (AVP) activity. However, test interpretation and AVP measurement are challenging. The objective was to evaluate the accuracy of copeptin, a stable peptide stoichiometrically cosecreted with AVP, in the differential diagnosis of polyuria-polydipsia syndrome. This was a prospective multicenter observational cohort study from four Swiss or German tertiary referral centers of adults >18 years old with the history of polyuria and polydipsia. A standardized combined water deprivation/3% saline infusion test was performed and terminated when serum sodium exceeded 147 mmol/L. Circulating copeptin and AVP levels were measured regularly throughout the test. Final diagnosis was based on the water deprivation/saline infusion test results, clinical information, and the treatment response. Fifty-five patients were enrolled (11 with complete central DI, 16 with partial central DI, 18 with PP, and 10 with nephrogenic DI). Without prior thirsting, a single baseline copeptin level >21.4 pmol/L differentiated nephrogenic DI from other etiologies with a 100% sensitivity and specificity, rendering a water deprivation testing unnecessary in such cases. A stimulated copeptin >4.9 pmol/L (at sodium levels >147 mmol/L) differentiated between patients with PP and patients with partial central DI with a 94.0% specificity and a 94.4% sensitivity. A stimulated AVP >1.8 pg/mL differentiated between the same categories with a 93.0% specificity and a 83.0% sensitivity. This study was limited by incorporation bias from including AVP levels as a diagnostic criterion. Copeptin is a promising new tool in the differential diagnosis of the polyuria-polydipsia syndrome, and a valid surrogate marker for AVP.

Low back pain in a child associated with acute onset cauda equina syndrome: a rare presentation of an aggressive vertebral hemangioma: a case report.

Back pain prevalence in the pediatric age group is less compared with adults. There is a wide range of possible etiologies, and tumors such as primary spinal hemangiomas are uncommon. Most are incidental findings and asymptomatic; however, painful lesions can be presented in up to 0.9% to 1.2% of cases. These lesions can produce neurologic involvement either spinal cord compression or cauda equina syndrome as in our case. The aim of this study is to describe a case of low back pain in a child due to a vertebral hemangioma complicated with acute cauda equina syndrome, and performed a literature review that will help us to recognize this aggressive variance making an early treatment feasible. A 13-year-old female, follow-up in an outer health care center due to a L1 vertebral hemangioma, characterized by 3 years of low back pain without neurologic symptoms presented to our emergency department with an acute cauda equina syndrome. An outside magnetic resonance imaging showed complete obliteration of the spinal canal at the level of the conus medullaris related to retropulsion of bone at L1. She underwent 2-stage surgical treatment: complete posterior L1 laminectomy and partial T12-L2 laminectomies, with partial L1 vertebrectomy and posterior fusion with instrumention from T11 to L3. Three weeks later, embolization before anterior fusion with inner body cage was performed. Forty months after surgery, she is doing well with no neurologic deficits. Even though hemangiomas are not a common cause of back pain, they should be taken into account. It is important to recognize the aggressive variance so an early treatment could be performed. There is no enough clinical data to establish guidelines of management in children, therefore, the treatment should be individualized.

Deficient Circumferential Growth Is the Primary Determinant of Aortic Obstruction Attributable to Partial Elastin Deficiency.

Williams syndrome is characterized by obstructive aortopathy attributable to heterozygous loss of ELN , the gene encoding elastin. Lesions are thought to result primarily from excessive smooth muscle cell (SMC) proliferation and consequent medial expansion, although an initially smaller caliber and increased stiffness of the aorta may contribute to luminal narrowing. The relative contributions of such abnormalities to the obstructive phenotype had not been defined. We quantified determinants of luminal stenosis in thoracic aortas of Eln -/- mice incompletely rescued by human ELN . Moderate obstruction was largely because of deficient circumferential growth, most prominently of ascending segments, despite increased axial growth. Medial thickening was evident in these smaller diameter elastin-deficient aortas, with medial area similar to that of larger diameter control aortas. There was no difference in cross-sectional SMC number between mutant and wild-type genotypes at multiple stages of postnatal development. Decreased elastin content was associated with medial fibrosis and reduced aortic distensibility because of increased structural stiffness but preserved material stiffness. Elastin-deficient SMCs exhibited greater contractile-to-proliferative phenotypic modulation in vitro than in vivo. We confirmed increased medial collagen without evidence of increased medial area or SMC number in a small ascending aorta with thickened media of a Williams syndrome subject. Deficient circumferential growth is the predominant mechanism for moderate obstructive aortic disease resulting from partial elastin deficiency. Our findings suggest that diverse aortic manifestations in Williams syndrome result from graded elastin content, and SMC hyperplasia causing medial expansion requires additional elastin loss superimposed on ELN haploinsufficiency. © 2017 American Heart Association, Inc.

Cystinosis, a main cause of Fanconi syndrome, is reproduced in congenic C57BL/6 cystinosin knockout (KO) mice. To identify the sequence of pathogenic and adaptation mechanisms of nephropathic cystinosis, we defined the onset of Fanconi syndrome in KO mice between 3 and 6 months of age and analyzed the correlation with structural and functional changes in proximal tubular cells (PTCs), with focus on endocytosis of ultrafiltrated disulfide-rich proteins as a key source of cystine. Despite considerable variation between mice at the same age, typical event sequences were delineated. At the cellular level, amorphous lysosomal inclusions preceded cystine crystals and eventual atrophy without crystals. At the nephron level, lesions started at the glomerulotubular junction and then extended distally. In situ hybridization and immunofluorescence revealed progressive loss of expression of megalin, cubilin, sodium-glucose cotransporter 2, and type IIa sodium-dependent phosphate cotransporter, suggesting apical dedifferentiation accounting for Fanconi syndrome before atrophy. Injection of labeled proteins revealed that defective endocytosis in S1 PTCs led to partial compensatory uptake by S3 PTCs, suggesting displacement of endocytic load and injury by disulfide-rich cargo. Increased PTC apoptosis allowed luminal shedding of cystine crystals and was partially compensated for by tubular proliferation. We conclude that lysosomal storage triggered by soluble cystine accumulation induces apical PTC dedifferentiation, which causes transfer of the harmful load of disulfide-rich proteins to more distal cells, possibly explaining longitudinal progression of swan-neck lesions. Furthermore, our results suggest that subsequent adaptation mechanisms include lysosomal clearance of free and crystalline cystine into urine and ongoing tissue repair. PMID:24525030

To evaluate the efficacy and safety of bronchoalveolar lavage (BAL) with diluted porcine surfactant in mechanically ventilated term infants with severe acute respiratory distress syndrome (ARDS) due to meconium aspiration syndrome (MAS). Eight consecutive mechanically ventilated term infants with severe ARDS due to MAS underwent BAL with 15 mL/kg of diluted (5.3mg phospholipid/mL) surfactant saline suspension (porcine surfactant [Curosurf]). Treatment was administered slowly in aliquots of 2.5 mL. The mean age of neonates at treatment was 3.5 (range 1-8) hours. Heart rate, systemic blood pressure and oxygen saturation were monitored continuously. Arterial blood gases were measured immediately before treatment, and again at 3 and 6 hours post-treatment. Chest x-rays were taken 6 and 24 hours after treatment. Radiological improvement was evident in all eight patients 6 hours post-treatment. Compared with pre-BAL values, significant improvements (p < 0.05) in mean values for partial pressure of oxygen in arterial blood, partial pressure of carbon dioxide in arterial blood, pH, arterial/alveolar O2 ratio and oxygenation index were documented at 3 and 6 hours after BAL. In all patients, tracheal fluids that had been meconium-stained prior to BAL were clear of meconium after BAL. Only one patient required nitric oxide therapy for transient pulmonary hypertension. No adverse sequelae of treatment occurred during the study. BAL with dilute porcine surfactant administered slowly in 2.5 mL aliquots improved oxygenation and chest x-ray findings, without causing major adverse effects, in mechanically ventilated term infants with ARDS due to MAS.

To study the effects of smoking restrictions in Germany on coronary syndromes and their associated costs. All German states implemented laws partially restricting smoking in the public and hospitality sectors between August 2007 and July 2008. We conducted a before-and-after study to examine trends for the hospitalization rate for angina pectoris and acute myocardial infarction (AMI) for an insurance cohort of 3,700,384 individuals 30 years and older. Outcome measures were hospitalization rates for coronary syndromes, and hospitalization costs. Mean age of the cohort was 56 years, and two-thirds were female. Some 2.2 and 1.1% persons were hospitalized for angina pectoris and AMI, respectively, during the study period from January 2004 through December 2008. Law implementation was associated with a 13.3% (95% confidence interval 8.2, 18.4) decline in angina pectoris and an 8.6% (5.0, 12.2) decline in AMI after 1 year. Hospitalization costs also decreased significantly for the two conditions-9.6% (2.5, 16.6) for angina pectoris and 20.1% (16.0, 24.2) for AMI at 1 year following law implementation. Assuming the law caused the observed declines, it prevented 1,880 hospitalizations and saved 7.7 million Euros in costs for this cohort during the year following law implementation. Partial smoking restrictions in Germany were followed by reductions in hospitalization for angina pectoris and AMI, declines that continued through 1 year following these laws and resulted in substantial cost savings. Strengthening the laws could further reduce morbidity and costs from acute coronary syndromes in Germany.

OBJECTIVES The prevalence and characteristics of fetal alcohol syndrome (FAS) and partial fetal alcohol syndrome (PFAS) were determined in a third primary school cohort in a community in South Africa (S.A.). METHODS An active case ascertainment, two-tier screening methodology, and the revised Institute of Medicine diagnostic criteria were employed among 818 first grade pupils. Characteristics of children with FAS and PFAS are contrasted with a randomly-selected control group. Data were collected and analyzed for children in the study regarding: 1.) physical growth and development, including dysmorphology, 2.) intelligence and behavioral characteristics, and 3.) their mother’s social, behavioral, and physical characteristics. RESULTS The rate of FAS and PFAS in this area continues as the highest reported in any overall community and is much higher than rates elsewhere. In this cohort it is 68.0 to 89.2 per 1,000. Severe episodic drinking on weekends among mothers of children with FAS and PFAS accounts for 96% of all alcohol consumed. Various measures of maternal drinking are significantly correlated with negative outcomes of children in the areas of non-verbal intelligence (-0.26), verbal intelligence (-0.28), problem behavior (0.31), and overall dysmorphology score (0.59). Significantly more FAS and PFAS exists among children of rural residents (OR = 3.79). CONCLUSIONS A high rate of FAS and PFAS was again documented in this community, and it has increased. Given population similarities, we suspect that other communities in the Western Cape Province of South Africa also have high rates. Programs for prevention are needed. PMID:17127017

The prevalence and characteristics of fetal alcohol syndrome (FAS) and partial FAS (PFAS) in the United States (US) are not well known. This active case ascertainment study in a Rocky Mountain Region City assessed the prevalence and traits of children with FAS and PFAS and linked them to maternal risk factors. Diagnoses made by expert clinical dysmorphologists in multidisciplinary case conferences utilized all components of the study: dysmorphology and physical growth, neurobehavior, and maternal risk interviews. Direct parental (active) consent was obtained for 1278 children. Averages for key physical diagnostic traits and several other minor anomalies were significantly different among FAS, PFAS, and randomly-selected, normal controls. Cognitive tests and behavioral checklists discriminated the diagnostic groups from controls on 12 of 14 instruments. Mothers of children with FAS and PFAS were significantly lower in educational attainment, shorter, later in pregnancy recognition, and suffered more depression, and used marijuana and methamphetamine during their pregnancy. Most pre-pregnancy and pregnancy drinking measures were worse for mothers of FAS and PFAS. Excluding a significant difference in simply admitting drinking during the index pregnancy (FAS and PFAS=75% vs. 39.4% for controls), most quantitative intergroup differences merely approached significance. This community's prevalence of FAS is 2.9-7.5 per 1000, PFAS is 7.9-17.7 per 1000, and combined prevalence is 10.9-25.2 per 1000 or 1.1-2.5%. Comprehensive, active case ascertainment methods produced rates of FAS and PFAS higher than predicted by long-standing, popular estimates. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Children with Noonan syndrome show rapid decline of growth in the first year of life and feeding problems are present in over 50%. The aim of this study was to explore whether growth decelerates because of feeding problems or other Noonan syndrome-related factors. We performed a retrospective, longitudinal cohort study of clinically and genetically diagnosed subjects with Noonan syndrome (n = 143). Questionnaires about the phenotypic-genotypic profile and reported feeding problems were sent to eligible subjects. Data on first-year growth was obtained from growth charts. Ninety-one participants were excluded because of different criteria. A total of 52 subjects with Noonan syndrome were included. The largest decline in weight and length standard deviation score (SDS) occurred in the first 2.5 months after birth (-1.93 and -1.15, respectively), with feeding problems causing a decline of 0.57 SDS in the remaining months. At 1 year, children with feeding problems were on average 290 g lighter and 0.8 cm shorter than children without feeding problems. Weight gain was also negatively influenced by having a PTPN11 mutation (n = 39) and a higher gestational age, whereas children of parents with Noonan syndrome and with a higher birth weight gained more weight. Growth in length was reduced by having cardiac surgery and a higher gestational age, but positively influenced by birth length and maternal height. Growth in children with Noonan syndrome is impaired right after birth and only partially associated with feeding problems. In addition, several specific Noonan syndrome-related factors seem to influence growth in the first year. © 2018 Wiley Periodicals, Inc.

Acute respiratory distress syndrome 40 years later: time to revisit its definition.

PubMed

Phua, Jason; Stewart, Thomas E; Ferguson, Niall D

2008-10-01

Acute respiratory distress syndrome is a common disorder associated with significant mortality and morbidity. The aim of this article is to critically evaluate the definition of acute respiratory distress syndrome and examine the impact the definition has on clinical practice and research. Articles from a MEDLINE search (1950 to August 2007) using the Medical Subject Heading respiratory distress syndrome, adult, diagnosis, limited to the English language and human subjects, their relevant bibliographies, and personal collections, were reviewed. The definition of acute respiratory distress syndrome is important to researchers, clinicians, and administrators alike. It has evolved significantly over the last 40 years, culminating in the American-European Consensus Conference definition, which was published in 1994. Although the American-European Consensus Conference definition is widely used, it has some important limitations that may impact on the conduct of clinical research, on resource allocation, and ultimately on the bedside management of such patients. These limitations stem partially from the fact that as defined, acute respiratory distress syndrome is a heterogeneous entity and also involve the reliability and validity of the criteria used in the definition. This article critically evaluates the American-European Consensus Conference definition and its limitations. Importantly, it highlights how these limitations may contribute to clinical trials that have failed to detect a potential true treatment effect. Finally, recommendations are made that could be considered in future definition modifications with an emphasis on the significance of accurately identifying the target population in future trials and subsequently in clinical care. How acute respiratory distress syndrome is defined has a significant impact on the results of randomized, controlled trials and epidemiologic studies. Changes to the current American-European Consensus Conference definition are likely to have an important role in advancing the understanding and management of acute respiratory distress syndrome.

Eagle's Syndrome

Pinheiro, Thaís Gonçalves; Soares, Vítor Yamashiro Rocha; Ferreira, Denise Bastos Lage; Raymundo, Igor Teixeira; Nascimento, Luiz Augusto; Oliveira, Carlos Augusto Costa Pires de

2013-01-01

Summary Introduction: Eagle's syndrome is characterized by cervicopharyngeal signs and symptoms associated with elongation of the styloid apophysis. This elongation may occur through ossification of the stylohyoid ligament, or through growth of the apophysis due to osteogenesis triggered by a factor such as trauma. Elongation of the styloid apophysis may give rise to intense facial pain, headache, dysphagia, otalgia, buzzing sensations, and trismus. Precise diagnosis of the syndrome is difficult, and it is generally confounded by other manifestations of cervicopharyngeal pain. Objective: To describe a case of Eagle's syndrome. Case Report: A 53-year-old man reported lateral pain in his neck that had been present for 30 years. Computed tomography (CT) of the neck showed elongation and ossification of the styloid processes of the temporal bone, which was compatible with Eagle's syndrome. Surgery was performed for bilateral resection of the stylohyoid ligament by using a transoral and endoscopic access route. The patient continued to present pain laterally in the neck, predominantly on his left side. CT was performed again, which showed elongation of the styloid processes. The patient then underwent lateral cervicotomy with resection of the stylohyoid process, which partially resolved his painful condition. Final Comments: Patients with Eagle's syndrome generally have a history of chronic pain. Appropriate knowledge of this disease is necessary for adequate treatment to be provided. The importance of diagnosing this uncommon and often unsuspected disease should be emphasized, given that correct clinical-surgical treatment is frequently delayed. The diagnosis of Eagle's syndrome is clinical and radiographic, and the definitive treatment in cases of difficult-to-control pain is surgical. PMID:25992033

Neonatal distraction in severe micrognathia patients may alleviate the need for tracheostomy. The authors' objectives in evaluating syndromic neonatal distraction cases were to: (1) document preoperative temporomandibular joint pathology, (2) compare the incidence of postoperative temporomandibular joint ankylosis, and (3) determine whether "unloading" the condyle tended to prevent temporomandibular joint pathology. Syndromic versus nonsyndromic micrognathic (and normal) patient temporomandibular joint abnormalities were compared preoperatively based on computed tomography scans and incisor opening (n = 110). Patient temporomandibular joint outcomes after neonatal mandibular distraction were compared with regard to ankylosis (n = 59). Condylar-loaded versus condylar-unloaded (with class II intermaxillary elastics) temporomandibular joint outcomes were compared based on imaging and the need for joint reconstruction (n = 25). Preoperative abnormalities of neonatal temporomandibular joint pathology on computed tomography scans were not significant: syndromic, 15 percent; nonsyndromic, 5.9 percent; and normal joints, 4.2 percent. Syndromic patients had a significantly greater interincisor distance decrease postoperatively (48 percent; p < 0.05) and at 1-year follow-up (28 percent; p < 0.05) compared with nonsyndromic patients. Also, computed tomography scans revealed that 28 percent of syndromic patients developed temporomandibular joint abnormalities, whereas nonsyndromic patients were unchanged. Condylar-loaded patients had worse clinical outcomes compared with condylar-unloaded patients (80 percent versus 7 percent) and required temporomandibular joint reconstruction for bony ankylosis (40 percent versus 0 percent) after distraction. Neonatal syndromic, micrognathia patients have increased temporomandibular joint pathology preoperatively and bony ankylosis after distraction but are protected with partial unloading of the condyle during distraction.

Carpal tunnel syndrome is the most frequent of tunnel syndromes in the field of the professional sphere. It is related to repetitive movements of flexion-extension of the wrist and fingers or to a support on the heel of the hands. To determine the posts in a risk and to specify the modalities of guaranteed reimbursement of professional carpal tunnel syndrome. A retrospective and descriptive study of 27 medical files of employees indemnified for professional carpal tunnel syndrome registered in the medical control services of the social security office in charge of medical insurance of Tunis and Sousse during a period of 10 years (1995-2004). There were 24 women and 3 men with the average age of 40 years all occupying posts in a risk. Their average time of service is 15 years. Tow-thirds of them work in the clothing and textile industry. The attack is bilateral in 13 cases. Nightly acroparaesthesia rules the clinical rate (44.44% of cases). Motor disorders are noted in the quarter of cases. The electromyogram had confirmed diagnosis in all of cases. The previous state study put in evidence the antecedent of carpal tunnel syndrome in 5 cases and diabetes in one case. Twenty-one patients had profit of permanent partial incapacity with a rate varying from 3 to 25%. Five had got a transfer of working place and one stayed in the same post with a half-time work. The professional origin of carpal tunnel syndrome must be called up in front of an activity in a risk. The reparation is done according to picture 82 of occupational diseases.

Interatrial block (IAB) is a well-known entity that is associated with an increased risk of atrial fibrillation (AF). This association is called Bayes' syndrome. The aim of our study was to define the prevalence of IAB among patients younger than 65 years undergoing cardiac surgery and determine whether there is an association between the presence of interatrial conduction delay and postoperative atrial fibrillation (POAF). A total of 207 patients were enrolled. Partial IAB was defined as P-wave>120ms. Advanced IAB was defined as P-wave>120ms+biphasic morphology in the inferior leads. Ocurrence of POAF was assessed and a comparative analysis was conducted between patients that did and did not develop AF. IAB prevalence was 78.3% (partial 66.2%, advanced 12.1%). POAF occurred in 28.5% of all patients, and was more frequent among patients with advanced IAB (44%) compared to 27.7% and 24.4% of POAF among patients with partial IAB and without IAB, respectively. Patients who developed POAF were significantly older, had significantly higher NTproBNP, higher prevalence of atrial enlargement and thyroid disease. After multivariate analysis, advanced IAB was found to be independently associated with POAF. IAB is a frequent finding among patients undergoing cardiac surgery. According to our results, advanced IAB is independently associated with POAF in younger patients (<65 years) undergoing cardiac surgery.

Abernethy malformation is a rare congenital anomaly characterised by the partial or complete absence of the portal vein and the subsequent development of an extrahepatic portosystemic shunt. Caroli's disease is a rare congenital condition characterised by non-obstructive saccular intrahepatic bile duct dilation. Caroli's disease combined with congenital hepatic fibrosis and/or renal cystic disease is referred to - Caroli's syndrome. The combination of Abernethy malformation and Caroli's syndrome has not been reported previously. We present the case of a 23-year-old female who was found to have both type II Abernethy malformation and Caroli's syndrome. Radiological imaging was performed, including computed tomography with three-dimensional reconstruction and magnetic resonance imaging with (magnetic resonance cholangiopancreatography (MRCP), which revealed a side-to-side portocaval shunt, intrahepatic bile duct dilation, congenital hepatic fibrosis, and renal cysts. In addition, PKHD1 (polycystic kidney and hepatic disease 1) gene mutational analysis revealed a paternally inherited heterozygous missense mutation (c.1877A > G, p.Lys626Arg). A liver biopsy confirmed the pathological features of Caroli's syndrome. To our knowledge, this is the first reported case of a patient with both type II Abernethy malformation and Caroli's syndrome diagnosed using a comprehensive approach that included imaging, mutational analysis, and liver biopsy. Additionally, this is the second reported case to date of an Asian patient presenting with liver and renal disorders with the same paternally inherited PKHD1 missense mutation.

Gene expression analysis of induced pluripotent stem cells from aneuploid chromosomal syndromes

PubMed Central

2013-01-01

Background Human aneuploidy is the leading cause of early pregnancy loss, mental retardation, and multiple congenital anomalies. Due to the high mortality associated with aneuploidy, the pathophysiological mechanisms of aneuploidy syndrome remain largely unknown. Previous studies focused mostly on whether dosage compensation occurs, and the next generation transcriptomics sequencing technology RNA-seq is expected to eventually uncover the mechanisms of gene expression regulation and the related pathological phenotypes in human aneuploidy. Results Using next generation transcriptomics sequencing technology RNA-seq, we profiled the transcriptomes of four human aneuploid induced pluripotent stem cell (iPSC) lines generated from monosomy × (Turner syndrome), trisomy 8 (Warkany syndrome 2), trisomy 13 (Patau syndrome), and partial trisomy 11:22 (Emanuel syndrome) as well as two umbilical cord matrix iPSC lines as euploid controls to examine how phenotypic abnormalities develop with aberrant karyotype. A total of 466 M (50-bp) reads were obtained from the six iPSC lines, and over 13,000 mRNAs were identified by gene annotation. Global analysis of gene expression profiles and functional analysis of differentially expressed (DE) genes were implemented. Over 5000 DE genes are determined between aneuploidy and euploid iPSCs respectively while 9 KEGG pathways are overlapped enriched in four aneuploidy samples. Conclusions Our results demonstrate that the extra or missing chromosome has extensive effects on the whole transcriptome. Functional analysis of differentially expressed genes reveals that the genes most affected in aneuploid individuals are related to central nervous system development and tumorigenesis. PMID:24564826

Partial duplications of the long arm of chromosome 3, dup(3q), are a rare but well-described condition, sharing features of Cornelia de Lange syndrome. Around two thirds of cases are derived from unbalanced translocations, whereas pure dup(3q) have rarely been reported. Here, we provide an extensive review of the literature on dup(3q). This search revealed several patients with caudal malformations and anomalies, suggesting that caudal malformations or anomalies represent an inherent phenotypic feature of dup(3q). In this context, we report a patient with a pure de novo duplication 3q26.32-q27.2. The patient had the clinical diagnosis of Currarino syndrome (CS) (characterized by the triad of sacral anomalies, anorectal malformations and a presacral mass) and additional features, frequently detected in patients with a dup(3q). Mutations within the MNX1 gene were found to be causative in CS but no MNX1 mutation could be detected in our patient. Our comprehensive search for candidate genes located in the critical region of the duplication 3q syndrome, 3q26.3-q27, revealed a so far neglected phenotypic overlap of dup(3q) and the Pierpont syndrome, associated with a mutation of the TBL1XR1 gene on 3q26.32. © 2016 John Wiley & Sons A/S.

Abstract We report the case of a 60-year-old Hispanic male with widespread necrotic purpuric lesions involving the penile, suprapubic, inguinal and hip dermis due to purpura fulminans. Purpura fulminans describes a rare syndrome involving intravascular thrombosis and hemorrhagic infarction of the skin; this rapidly progressing syndrome features vascular collapse and disseminated intravascular coagulation. This patient’s penile necrosis involved the majority of the penile shaft and glans penis, and ultimately required partial glansectomy and repeated debridement for treatment. Subsequently, full thickness skin grafting was completed for reconstruction with good effect. While reports of penile necrosis secondary to various causes are documented in the literature, no prior reports describe penile necrosis secondary to purpura fulminans. PMID:28479975

We herein report a 31-year-old Japanese woman with evolving hypopituitarism due to pituitary stalk transection syndrome. She had a history of short stature treated with growth hormone (GH) in childhood and had hypothyroidism and primary amenorrhea at 20 years old. Levothyroxine replacement and recombinant follicle stimulating hormone-human chorionic gonadotropin (FSH-hCG) therapy for ovulation induction were started. GH replacement therapy (GHRT) was resumed when she was 26 years old. She developed mild adrenocortical insufficiency at 31 years old. She succeeded in becoming pregnant and delivered twice. GHRT was partially continued during pregnancy and stopped at the end of the second trimester without any complications. PMID:28250299

Polycystic ovary syndrome (PCOS) is an endocrinological abnormality which typically presents as hormones disorder and/or infertility. It has received more and more attention in recent years though its pathogenesis is still unclear. Ovarian mucinous adenoma is a rarely pathological type which generates from epithelial cell of ovary. Here we present a patient with PCOS and ovarian mucinous tumor (occasionally discovered by cesarean section) receiving a complete relief after benign ovarian tumor excision. In this case, tumor excision played as a partial resection of ovary which might result in the normalized concentration level of hormones and morphology of ovary. This report suggests that therapeutic strategies for PCOS should be considered more carefully and individually.

We report two patients with velo-cardio-facial syndrome (VCFS) who were admitted to our pediatric endocrinology clinic because of short stature and followed longitudinally until attainment of final height. Both patients followed a growth pattern consistent with constitutional delay of puberty with normal and near normal final height. Case 2 also had partial growth hormone (GH) deficiency and severe short stature (height SDS -3.4 SDS), but showed spontaneous catch-up and ended up with a final height of -2 SDS. These cases suggest that short stature in children with VCFS is due to a pattern of growth similar to that observed in constitutional delay of growth and puberty.

We describe moderate hyperbilirubinemia in a 28-year-old man who suffered from gallstones and splenomegaly, with combined disorders of hereditary spherocytosis (HS) and Gilbert's syndrome (GS). Since it is difficult to diagnose HS in the absence of signs of anemia, we evaluated both the genetic mutation in the UGT1A1 gene and abnormalities in the erythrocyte membrane protein; the former was heterozygous for a UGT1A1 allele with three mutations and the latter was partially deficient in ankyrin expression. This is the first report of the concomitance of HS and GS with three heterozygous mutations [T-3279G, A (TA)7TAA, and G211A] in the UGT1A1 gene. PMID:20924216

Patients with 1q duplication have demonstrated a wide range of multiple congenital abnormalities. Alterations involving this chromosomal region have being described in hematopoietic malignancies and a series of candidate genes that may be associated with neoplasias have been mapped in this region. We describe a case of partial trisomy 1q "syndrome" and acute monocytic leukemia. Cytogenetic study of the bone marrow cells by GTG-banding and spectral karyotyping (SKY) showed dup(1)(q23q44) in all cells analyzed. The dismorphological features with the dup(1q) suggest a constitutional chromosome alteration and the first, in our knowledge, association of a trisomy 1q "syndrome" with AML.

Three patients diagnosed with Wernicke-Korsakoff syndrome were treated with the acetylcholinesterase inhibitor, donepezil, for periods of 6 to 8 months. Cognitive testing [Alzheimer's disease assessment scale-cognitive subscale (ADAS-Cog), Mini-mental state examination (MMSE), Clock drawing test and six item 2 min recall] and carer questionnaires [Informant Questionnaire (IQ Code), Neuropsychiatric inventory scale (NPI)] were performed at baseline, mid- and endpoint of the treatment period and post-discontinuation. Progressive partial improvement occurred in cognitive measurements through the treatment period, some of which was sustained after discontinuing donepezil. Carer questionnaires also indicated improvement. Confounding factors necessitate caution when attributing improvements to the medication, but these cases suggest that this option merits further investigation.

Obstructive Sleep Apnea Syndrome (OSAS) is a sleeping disorder caused by repeated episodes of partial or complete obstruction of the upper airways during sleep. During 2013, a pilot project was performed in the Marche region (Italy), co-jointly by the University "Politecnica delle Marche" and the Italian National Institute of Work Accident Insurance (INAIL), among holders of a category "B" driver's licence and among professionals undergoing screening at an Occupational Medicine Service covering the Province of Pesaro-Urbino (Italy). Nineteen percent of 553 subjects undergoing a screening examination were found to be affected by OSAS. The data collected is of great interest in the phase of implementation of new national laws.

Autistic spectrum disorders (ASD) is a term that is not included in DSM IV or in ICD 10, which are the diagnostic tools most commonly used by clinical professionals but can offer problems in research when it comes to finding homogenous groups. From a neuropaediatric point of view, there is a need for a classification of the generalised disorders affecting development and for this purpose we used Wing's triad, which defines the continuum of the autistic spectrum, and the information provided by magnetoencephalography (MEG) as grouping elements. Specific generalised developmental disorders were taken as being those syndromes that partially expressed some autistic trait, but with their own personality so that they could be considered to be a specific disorder. ASD were classified as being primary, cryptogenic or secondary. The primary disorders, in turn, express a continuum that ranges from Savant syndrome to Asperger's syndrome and the different degrees of early infantile autism. MEG is a functional neuroimaging technique that has enabled us to back up this classification.

A 13-year-old, obese girl presented with acute abdominal pain with abdominal distension for a year. The physical examination revealed marked abdominal distension with a large well-circumscribed mass sized 13×20 cm. Her body mass index (BMI) was 37.8 kg/m2. An abdominal CT scan revealed a huge multiloculated cystic mass and a left adnexal mass. She had an abnormal fasting plasma glucose and low HDL-C. Laparotomy, right salpingooophorectomy, left cystectomy, lymph node biopsies and partial omentectomy were performed. The left ovary demonstrated multiple cystic follicles over the cortex. The histologic diagnosis was a mucinous cystadenoma of the right ovary and a matured cystic teratoma of the left ovary. Both obesity and polycystic ovary syndrome (PCOS) are associated with a greater risk of ovarian tumours, where PCOS could be either the cause or as a consequence of an ovarian tumour. We report an obese, perimenarchal girl with bilateral ovarian tumours coexistent with a polycystic ovary and the metabolic syndrome.

Celiprolol

Celiprolol is a β-blocker with a unique pharmacologic profile: it is a β1-andrenoceptor antagonist with partial β2 agonist activity. Given this combination of effects, celiprolol may be better described as a selective adrenoreceptor modulator. It has antihypertensive and antianginal properties and is indicated for those uses in various countries around the world. In the United States, however, the proposed indication for this drug will be for the treatment of vascular type Ehlers–Danlos syndrome, a rare connective tissue disorder characterized by fragile arterial structure and an increased risk of life-threatening vascular complications. By reducing heart rate and pulsatile pressure, celiprolol may reduce the mechanical stress on collagen fibers within the arterial wall and be of benefit in patients with vascular type Ehlers–Danlos syndrome. The largest investigation of celiprolol in vascular Ehlers–Danlos syndrome was prematurely terminated due to significant benefit with celiprolol in reducing arterial events in patients with this condition. Celiprolol, therefore, represents a β-blocker that is unique from others in its class in both its pharmacology and clinical applications. PMID:28742547

Job-related diseases and occupations within a large workers' compensation data set.

Leigh, J P; Miller, T R

1998-03-01

The objective of this report is to describe workers' job-related diseases and the occupations associated with those diseases. The methods include aggregation and analysis of job-related disease and occupation data from the Bureau of Labor Statistics' Supplementary Data System (SDS) for 1985 and 1986--the last years of data available with workers' compensation categories: death, permanent total, permanent partial, and temporary total and partial. Diseases are ranked according to their contribution to the four workers' compensation (WC) categories and also ranked within occupations according to the number of cases. Occupations are ranked according to their contribution to specific diseases within one of the four categories. The following diseases comprise the greatest numbers of deaths: heart attacks, asbestosis, silicosis, and stroke. Within the permanent total category, the diseases with the greatest contributions are heart attack, silicosis, strokes, and inflammation of the joints. For the permanent partial category, they are hearing loss, inflammation of joints, carpal tunnel syndrome, and heart attacks. For the temporary total and partial category, they are: inflammation of joints, carpal tunnel syndrome, dermatitis, and toxic poisoning. Hearing loss or inflammation of joints are associated with more than 300 occupations. Circulatory diseases comprise a larger share of job-related diseases than is generally acknowledged. Occupations contributing the most heart attack deaths are truck drivers, managers, janitors, supervisors, firefighters, and laborers. Ratios of numbers of deaths to numbers of disabilities are far higher for illnesses than injuries. Occupations that are consistent in their high ranking on most lists involving a variety of conditions include nonconstruction laborers, janitors, and construction laborers. The large SDS, though dated, provides a tentative national look at the broad spectrum of occupational diseases as defined by WC and the occupations associated with those diseases in 1985 and 1986. Some description of the spectrum of diseases encountered today is possible especially for occupations, such as those mentioned above for which employment has expanded in the 1990s.

Less Structured Movement Patterns Predict Severity of Positive Syndrome, Excitement, and Disorganization

Disorganized behavior is a key symptom of schizophrenia. The objective assessment of disorganized behavior is particularly challenging. Actigraphy has enabled the objective assessment of motor behavior in various settings. Reduced motor activity was associated with negative syndrome scores, but simple motor activity analyses were not informative on other symptom dimensions. The analysis of movement patterns, however, could be more informative for assessing schizophrenia symptom dimensions. Here, we use time series analyses on actigraphic data of 100 schizophrenia spectrum disorder patients. Actigraphy recording intervals were set at 2 s. Data from 2 defined 60-min periods were analyzed, and partial autocorrelations of the actigraphy time series indicated predictability of movements in each individual. Increased positive syndrome scores were associated with reduced predictability of movements but not with the overall amount of movement. Negative syndrome scores were associated with low activity levels but unrelated with predictability of movement. The factors disorganization and excitement were related to movement predictability but emotional distress was not. Thus, the predictability of objectively assessed motor behavior may be a marker of positive symptoms and disorganized behavior. This behavior could become relevant for translational research.

Alport syndrome is an inherited progressive nephropathy arising from mutations in the type IV collagen genes, COL4A3, COL4A4, and COL4A5. Symptoms also include sensorineural hearing loss and ocular lesions. We determined the molecular basis of Alport syndrome in a non-consanguineous Ashkenazi Jewish family with multiple affected females using linkage analysis and next generation sequencing. We identified a homozygous COL4A3 mutation, c.40_63del, in affected individuals with mutant alleles inherited from each parent on partially conserved haplotypes. Large-scale population screening of 2017 unrelated Ashkenazi Jewish samples revealed a carrier frequency of 1 in 183 indicating that COL4A3 c.40_63del is a founder mutation which may be a common cause of Alport syndrome in this population. Additionally, we determined that heterozygous mutation carriers in this family do not meet criteria for a diagnosis of Thin Basement Membrane Nephropathy and concluded that carriers of c.40_63del are not likely to develop benign familial hematuria. © 2013 John Wiley & Sons A/S.

Spondyloarthropathy has been described radiographically in patients following paralysis from spinal cord trauma. Onset of these findings after cauda equina syndrome have not been reported previously. Furthermore, the magnetic resonance documentation of its early evolution has not been recorded. We report a case of early-onset spondyloarthropathy shown by magnetic resonance imaging (MRI) in a patient with cauda equina syndrome due to bilateral sacral insufficiency fractures. Unique case study review, one case. Review of the clinical case notes and imaging including initial and subsequent MR imaging. The initial MRI of the lumbosacral spine showed bilateral sacral insufficiency fractures with a kyphotic deformity. The vertebral bodies were normal on the initial computed tomography and MRI studies, which did not reveal pre-existing features of sacroiliitis. The second MRI performed 5 months later clearly showed spondylitis at multiple vertebral levels with partial resolution 18 months post injury. Spondyloarthropathy in patients with paralysis due to spinal cord injury is well documented in the English language literature, but until now this has not been demonstrated by MRI. It is a rare complication of traumatic cauda equina syndrome that commences soon after the traumatic event and can resolve spontaneously.

Case report of surgically treated mechanical low back pain from the facet joint contralateral to a unilateral anomalous lumbosacral articulation (Bertolotti's syndrome). To describe the clinical presentation, diagnostic evaluation, and management of facet-related low back pain in a 17-year-old cheerleader and its successful surgical treatment with resection of a contralateral anomalous articulation. Lumbosacral transitional vertebrae are common in the general population. Bertolotti's syndrome is mechanical low back pain associated with these transitional segments. Little is known about the pathophysiology and mechanics of these vertebral segments and their propensity to be pain generators. Treatment of this syndrome is controversial, and surgical intervention has been infrequently reported. A retrospective chart analysis and radiographic review were performed. Repeated fluoroscopically guided injections implicated a symptomatic L6-S1 facet joint contralateral to an anomalous lumbosacral articulation. Eventually, a successful surgical outcome was achieved with resection of the anomalous articulation. Clinicians should consider the possibility that mechanical low back pain may occur from a facet contralateral to a unilateral anomalous lumbosacral articulation, even in a young patient. Although reports of surgical treatment of Bertolotti's syndrome are infrequent, resection of the anomalous articulation provided excellent results in this patient, presumably because of reduced stresses on the symptomatic facet.

Seven patients with a rare syndrome of diabetes insipidus (DI), diabetes mellitus (DM), optic atrophy (OA), neurosensory deafness (D), atony of the urinary tract, and other abnormalities (Wolfram or DIDMOAD syndrome) are reported. Of the seven patients, three siblings were followed up for 10-17 years. All seven patients had diabetes mellitus and optic atrophy; six had diabetes insipidus; and in the four patients investigated there was dilatation of the urinary tract. The severity of diabetes varied, and all required insulin for control of the hyperglycaemia. In one patient the course of the disease simulated maturity onset diabetes of the young; another presented with ketoacidosis; but none had haplotypes usually associated with insulin dependent diabetes mellitus. The diabetes insipidus responded to chlorpropamide, suggesting partial antidiuretic hormone deficiency. Onset of optic atrophy and loss of vision occurred relatively late and progressed slowly, although in one patient there was a rapid deterioration in visual acuity. Deafness was mild, of late onset, and of sensorineural origin. A degenerative process affecting the central and peripheral nervous system can explain all the manifestations of the syndrome except diabetes mellitus. The pathogenesis of the diabetes mellitus remains obscure. PMID:4051539

The partial exchange transfusions necessary for management of some sickle-cell complications raise the issue of effectiveness in the context of limited resources and inadequate blood safety. This study evaluated the effectiveness, safety, and cost of partial exchange transfusions in 39 patients with sickle-cell anemia in Lubumbashi, looking at the patients' age and gender and the tolerability and direct cost of the transfusions. Excel and SPSS 18 were used for data entry and analysis. Chi2 and Fisher exact tests were used for comparisons. A P-value ≤ 5% was considered statistically significant. The average age of patients was 8.6 ± 6.4 years, and the majority were girls. The most frequent indications were stroke, severe infections, severe vasooclusive crises, and acute chest syndrome. Partial exchange transfusions were effective in improving hemoglobin and hematocrit as well as the percentage of HbS. No acute accident was observed during any partial exchange transfusion; one anti-Kell alloimmunization and 2 cases of iron overload were observed. The annual cost of partial exchange transfusions per patient requiring (and able to afford) regular treatment was US $ 3,345 without iron chelation and more than US $ 5000 with chelation. Partial exchange transfusions are effective and tolerated, but financially inaccessible to the majority of our sickle cell patients. Thus, an assessment is needed of the economic burden of sickle cell complications that require partial exchange transfusions in the context of countries with limited financial resources.

This study aims to investigate the metabolic profiles of postoperative colorectal cancer (PCRC) patients with different traditional Chinese medicine (TCM) syndromes and to discuss the metabolic mechanism under PCRC progression and TCM syndrome classification. Fifty healthy controls (HC) and 70 PCRC patients, including 10 Dampness and heat syndrome (DHS), 33 Spleen deficiency syndrome (SDS), 19 Liver and kidney Yin deficiency syndrome (LKYDS) and 8 with non-TCM syndrome (NS) were enrolled. Plasma metabolic profiles were detected by Gas chromatography-mass spectrometry (GC-MS) and analyzed by principal component analysis (PCA) and partial least squares-discriminate analysis (PLS-DA). Furthermore, pathway enrichment was analyzed based on KEGG and DAVID databases and metabolic network was constructed via metaboanalyst and cytoscape. The top-3 metabolites with higher abundance in PCRC compared with HC were terephthalic acid (165.417-fold), ornithine (24.484-fold) and aminomalonic acid (21.346-fold). And the cholesterol (0.588-fold) level was decreased in PCRC. l-Alanine, 1, 2-ethanediamine, urea, glycerol, glycine, aminomalonic acid, creatinine and palmitic acid were specifically altered in the DHS, while d-tryptophan was exclusively changed in SDS, and l-proline, 1, 2, 3-propanetricarboxylic acid, d-galactose and 2-indolecarboxylic acids in LKYDS. The plasma metabolic profiles were perturbed in PCRC patients. Increased levels of terephthalic acid might indicate high risk of relapse and elevated ornithine may contribute to the post-operational recovery or may raise the susceptibility to PCRC recurrence. The metabolic profiles of DHS, SDS, LKYDS and NS were almost separately clustered, indicating the possibility of explaining TCM syndromes classification using metabolomics. Furthermore, creatinine and aminomalonic acid alternation might correlate with the formation of DHS, while d-tryptophan may associate with SDS and d-galactose and 1, 2, 3-propanetricarboxylic acid may relate to LKYDS. As numbers of patients in each TCM syndrome are small, further study is needed to verify those results. Copyright © 2017 Elsevier Ltd. All rights reserved.

Although specialized interactions, including those involving plants and their pollinators, are often invoked to explain high species diversity, they are rarely explored at macroevolutionary scales. We investigate the dynamic evolution of hummingbird and bat pollination syndromes in the centropogonid clade (Lobelioideae: Campanulaceae), an Andean-centered group of ∼550 angiosperm species. We demonstrate that flowers hypothesized to be adapted to different pollinators based on flower color fall into distinct regions of morphospace, and this is validated by morphology of species with known pollinators. This supports the existence of pollination syndromes in the centropogonids, an idea corroborated by ecological studies. We further demonstrate that hummingbird pollination is ancestral, and that bat pollination has evolved ∼13 times independently, with ∼11 reversals. This convergence is associated with correlated evolution of floral traits within selective regimes corresponding to pollination syndrome. Collectively, our results suggest that floral morphological diversity is extremely labile, likely resulting from selection imposed by pollinators. Finally, even though this clade's rapid diversification is partially attributed to their association with vertebrate pollinators, we detect no difference in diversification rates between hummingbird- and bat-pollinated lineages. Our study demonstrates the utility of pollination syndromes as a proxy for ecological relationships in macroevolutionary studies of certain species-rich clades. © 2017 The Author(s).

Obesity-related disorders, especially metabolic syndrome, contribute to 2.8 million deaths each year worldwide, with significantly increasing morbidity. Eating at regular times and proper food quantity are crucial for maintaining a healthy status. However, many people in developed countries do not follow a regular eating schedule due to a busy lifestyle. Herein, we show that a repeated sense of hunger leads to a high risk of developing visceral obesity and metabolic syndrome in a mouse model (both 3-week and 6-week-old age, 10 mice in each group). The ad libitum (AL) group (normal eating pattern) and the food restriction (FR) group (alternate-day partially food restriction by given only 1/3 of average amount) were compared after 8-week experimental period. The total food consumption in the FR group was lower than in the AL group, however, the FR group showed a metabolic syndrome-like condition with significant fat accumulation in adipose tissues. Consequently, the repeated sense of hunger induced the typical characteristics of metabolic syndrome in an animal model; a distinct visceral obesity, hyperlipidemia, hyperglycemia and hepatic steatosis. Furthermore, we found that specifically leptin, a major metabolic hormone, played a major role in the development of these pathological disorders. Our study indicated the importance of regular eating habits besides controlling calorie intake.

Anton-Babinski syndrome is a rare disease featuring bilateral cortical blindness and anosognosia with visual confabulation, but without dementia or any memory impairment. It has a unique neuropsychiatric presentation and should be highly suspected in those with odd visual loss and imaging evidence of occipital lobe injury. In the case discussed herein, a 90-year-old man presented with bilateral blindness, obvious anosognosia, and vivid visual confabulation, which he had had for 3 days. Brain computed tomography demonstrated recent hypodense infarctions at the bilateral occipital lobes. Thus, the patient was diagnosed with Anton-Babinski syndrome. Because of his age and the thrombolytic therapy during the golden 3 hours after ischemic stroke, the patient received aspirin therapy rather than tissue plasminogen activator or warfarin. He gradually realized he was blind during the following week, but died of pneumonia 1 month later. In the literature, it is difficult to establish awareness of blindness in patients with Anton-Babinski syndrome, but optimistically, in one report, a patient was aware of blindness within 2 weeks, without vision improvement. Our case illustrates that elderly patients with Anton-Babinski syndrome can partially recover and that 1 week is the shortest time for the establishment of awareness of blindness for sufferers without vision improvement. © 2014 The Authors.

To evaluate possible monogenic and chromosomal anomalies in a patient with unilateral Duane retraction syndrome, modest dysmorphism, cerebral white matter abnormalities, and normal cognitive function. Performing high-resolution array comparative genomic hybridization (array CGH) and sequencing of HOXA1, KIF21A, SALL4, and CHN1 genes. The proband had unilateral Duane retraction syndrome (DRS) type III on the right with low-set ears, prominent forehead, clinodactyly, and a history of frequent infections during early childhood. Motor development and cognitive function were normal. Parents were not related, and no other family member was similarly affected. MRI revealed multiple small areas of high signal on T2 weighted images in cerebral white matter oriented along white matter tracts. Sequencing of HOXA1, KIF21A, SALL4, and CHN1 did not reveal any mutation(s). Array CGH showed a 95 Kb de novo duplication on chromosome 19q13.4 encompassing four killer cell immunoglobulin-like receptor (KIR) genes. Conclusions. KIR genes have not previously been linked to a developmental syndrome, although they are known to be expressed in the human brain and brainstem and to be associated with certain infections and autoimmune diseases, including some affecting the nervous system. DRS and brain neuroimaging abnormalities may imply a central and peripheral oligodendrocyte abnormality related in some fashion to an immunomodulatory disturbance.

Update on oral-facial-digital syndromes (OFDS).

PubMed

Franco, Brunella; Thauvin-Robinet, Christel

2016-01-01

Oral-facial-digital syndromes (OFDS) represent a heterogeneous group of rare developmental disorders affecting the mouth, the face and the digits. Additional signs may involve brain, kidneys and other organs thus better defining the different clinical subtypes. With the exception of OFD types I and VIII, which are X-linked, the majority of OFDS is transmitted as an autosomal recessive syndrome. A number of genes have already found to be mutated in OFDS and most of the encoded proteins are predicted or proven to be involved in primary cilia/basal body function. Preliminary data indicate a physical interaction among some of those proteins and future studies will clarify whether all OFDS proteins are part of a network functionally connected to cilia. Mutations in some of the genes can also lead to other types of ciliopathies with partially overlapping phenotypes, such as Joubert syndrome (JS) and Meckel syndrome (MKS), supporting the concept that cilia-related diseases might be a continuous spectrum of the same phenotype with different degrees of severity. To date, seven of the described OFDS still await a molecular definition and two unclassified forms need further clinical and molecular validation. Next-generation sequencing (NGS) approaches are expected to shed light on how many OFDS geneticists should consider while evaluating oral-facial-digital cases. Functional studies will establish whether the non-ciliary functions of the transcripts mutated in OFDS might contribute to any of the phenotypic abnormalities observed in OFDS.

Cushing's syndrome is associated with increased mortality, mainly due to cardiovascular complications, which are sustained by the common development of systemic arterial hypertension and metabolic syndrome, which partially persist after the disease remission. Cardiovascular diseases and hypertension associated with endogenous hypercortisolism reveal underexplored peculiarities. The use of exogenous corticosteroids also impacts on hypertension and cardiovascular system, especially after prolonged treatment. The mechanisms involved in the development of hypertension differ, whether glucocorticoid excess is acute or chronic, and the source endogenous or exogenous, introducing inconsistencies among published studies. The pleiotropic effects of glucocorticoids and the overlap of the several regulatory mechanisms controlling blood pressure suggest that a rigorous comparison of in-vivo and in-vitro studies is necessary to draw reliable conclusions. This review, developed during the first 'Altogether to Beat Cushing's syndrome' workshop held in Capri in 2012, evaluates the most important peculiarities of hypertension associated with CS, with a particular focus on its pathophysiology. A critical appraisal of most significant animal and human studies is compared with a systematic review of the few available clinical trials. A special attention is dedicated to the description of the clinical features and cardiovascular damage secondary to glucocorticoid excess. On the basis of the consensus reached during the workshop, a pathophysiology-oriented therapeutic algorithm has been developed and it could serve as a first attempt to rationalize the treatment of hypertension in Cushing's syndrome.

Depression in obese patients with primary fibromyalgia: the mediating role of poor sleep and eating disorder features.

Depression is a prominent feature in fibromyalgia syndrome. Patients with fibromyalgia syndrome who are obese, with poor sleep quality, and those who have recurrent episodes of binge eating are at greater risk to develop depression. The aim of this cross-sectional study was to examine the hypothesis that the relationship between obesity and depression in patients with primary fibromyalgia syndrome is mediated by poor sleep, binge eating disorder (BED), and weight and shape concern. This study included 131 patients with primary fibromyalgia syndrome. Participants completed the following questionnaires: Pittsburgh Sleep Quality Index, Beck Depression Inventory-II, Eating Disorder questionnaire, and Fibromyalgia Impact Questionnaire. Body mass index (BMI) provided the primary indicator of obesity. Sobel test showed that the conditions for complete mediation were satisfied on the weight and shape concern as mediator between BMI and depression because the association between BMI and depression score became insignificant after controlling of weight and shape concern. However, since the association between BMI and depression remained significant after BED and poor sleep score were controlled, thus for both mediators, the conditions for partial mediation on the depression were satisfied. The findings suggest that in patients with primary fibromyalgia syndrome, weight and shape concern, BED, and poor sleep quality are important mediators of the relationship between obesity and depression. We suggest that a greater focus on these mediators in depression treatment may be indicated.

Anomalous pulmonary venous connection is an uncommon congenital anomaly in which all (total form) or some (partial form) pulmonary veins drain into a systemic vein or into the right atrium rather than into the left atrium. The authors present one case of total anomalous pulmonary venous connection and two cases of partial anomalous pulmonary venous connection, one of supracardiac drainage into the brachiocephalic vein, and the other of infracardiac anomalous venous drainage (scimitar syndrome). Through the presentation of these cases, this article aims to review the main pulmonary venous developmental defects, highlighting the role of imaging techniques in the assessment of these anomalies.

Baseline and stimulated peak values of GH were not significantly different between the two groups. At +120 minutes, GH levels remained significantly higher (p = 0.0121) in comparison with baseline values in children with Noonan syndrome. Baseline IGFI levels in patients and in SS controls were not significantly different, in contrast to values after the rGH generation test [205 ng/mL (interquartiles 138.2-252.5 ng/mL) and 284.5 ng/mL (interquartiles 172-476 ng/mL), respectively; p = 0.0248]. IGF1 values were significantly related to height (baseline: r = 773, p = 0.0320; peak: r = 0.591, p = 0.0428) in children with Noonan syndrome. Blunted increase of IGF1 after the rGH generation test was present in children with Noonan syndrome due to mutations in the PTPN11 gene in comparison with SS children. This finding may be due to partial GH resistance in the former likely related to altered Ras-MAPK signaling pathway.

Pediatric patients with end-stage renal failure due to severe drug-resistant nephrotic syndrome are at risk of rapid recurrence after renal transplantation. Treatment options include plasmapheresis, high-dose of cyclosporine A/methylprednisolone and more recently-rituximab (anti-B CD20 monoclonal depleting antibody). We report five patients with immediate (1-2 days) post-transplant recurrence of nephrotic syndrome, treated with this kind of combined therapy including 2-4 weekly doses of 375 mg/m(2) of rituximab. Only two (of five) patients have showed full long-term remission, while the partial remission was seen in two cases, and no clinical effect at all was achieved in one patient. The correlation between B CD19 cells depletion and clinical effect was present in two cases only. Severe adverse events were present in two patients, including one fatal rituximab-related acute lung injury. The anti-CD20 monoclonal antibody may be not effective in all pediatric cases of rapid post-transplant recurrence of nephrotic syndrome, and benefit/risk ratio must be carefully balanced on individual basis before taking the decision to use this protocol. • nephrotic syndrome may recur immediately after renal transplantation • plasmapheresis combined with pharmacotherapy is used as rescue management • rituximab was reported as effective drug both in primary and post-transplant nephrotic syndrome What is New: • rituximab may not be effective is several cases of post-transplant nephrotic syndrome due to variety of underlying mechanisms of the disease, which may be or not be responsive to this drug • there may be no correlation between drug-induced depletion of specific B cells and clinical effect; this might suggest B-cell independent manner of rituximab action.

Treacher–Collins–Franceschetti syndrome (TCS) is an autosomal dominant craniofacial disorder characterised by midface hypoplasia, micrognathia, downslanting palpebral fissures, eyelid colobomata, and ear deformities that often lead to conductive deafness. A total of 182 patients with signs consistent with a diagnosis of TCS were screened by DNA sequence and dosage analysis of the TCOF1 gene. In all, 92 cases were found to have a pathogenic mutation by sequencing and 5 to have a partial gene deletion. A further case had a novel in-frame deletion in the alternatively spliced exon 6A of uncertain pathogenicity. The majority of the pathogenic sequence changes were found to predict premature protein termination, however, four novel missense changes in the LIS1 homology motif at the 5′ end of the gene were identified. The partial gene deletions of different sizes represent ∼5.2% of all the pathogenic TCOF1 mutations identified, indicating that gene rearrangements account for a significant proportion of TCS cases. This is the first report of gene rearrangements resulting in TCS. These findings expand the TCOF1 mutation spectrum indicating that dosage analysis should be performed together with sequence analysis, a strategy that is predicted to have a sensitivity of 71% for patients in whom TCS is strongly suspected.

Abstract Hemorrhagic fever with renal syndrome (HFRS) has been confirmed by serological methods during recent years in Romania. In the present study, focus-reduction neutralization tests (FRNT) confirmed Dobrava hantavirus (DOBV) as the causative agent in some HFRS cases, but could not distinguish between DOBV and Saaremaa virus (SAAV) infections in other cases. DOBV was detected by a DOBV-specific TaqMan assay in sera of nine patients out of 22 tested. Partial sequences of the M genomic segment of DOBV were obtained from sera of three patients and revealed the circulation of two DOBV lineages in Romania. Investigation of rodents trapped in Romania found three DOBV-positive Apodemus flavicollis out of 83 rodents tested. Two different DOBV lineages were also detected in A. flavicollis as determined from partial sequences of the M and S genomic segments. Sequences of DOBV in A. flavicollis were either identical or closely related to the sequences obtained from the HFRS patients. The DOBV strains circulating in Romania clustered in two monophyletic groups, together with strains from Slovenia and the north of Greece. This is the first evidence for the circulation of DOBV in wild rodents and for a DOBV etiology of HFRS in Romania. PMID:24746107

To ascertain the immediate outcome of preterm infants with respiratory distress syndrome (RDS) on Bubble CPAP and identify risk factors associated with its failure. Prospective analytical study. Inborn preterm infants (gestation 28 to 34 weeks) admitted to the NICU with respiratory distress and chest X ray suggestive of RDS. Bubble CPAP with bi-nasal prongs. CPAP failures infants requiring ventilation in the first one week. 56 neonates were enrolled in the study. 14 (25%) babies failed CPAP. The predictors of failure were; no or only partial exposure to antenatal steroids, white-out on the chest X-ray, patent ductus arteriosus, sepsis/pneumonia and Downes score > 7 or FiO2 > or = 50% after 15-20 minutes of CPAP. Other maternal and neonatal variables did not influence the need for ventilation. Rates of mortality and duration of oxygen requirement was significantly higher in babies who failed CPAP. Only two infants developed pneumothorax. No baby had chronic lung disease. Infants with no or partial exposure to antenatal steroids, white-out chest X-ray, patent ductus arteriosus, sepsis/pneumonia and those with higher FiO2 requirement after initial stabilization on CPAP are at high risk of CPAP failure (needing mechanical ventilation). Bubble CPAP is safe for preterm infants with RDS.

Accessory proteins 8b and 8ab of severe acute respiratory syndrome coronavirus suppress the interferon signaling pathway by mediating ubiquitin-dependent rapid degradation of interferon regulatory factor 3.

Severe acute respiratory syndrome coronavirus (SARS-CoV) is an inefficient inducer of interferon (IFN) response. It expresses various proteins that effectively circumvent IFN production at different levels via distinct mechanisms. Through the construction of recombinant IBV expressing proteins 8a, 8b and 8ab encoded by SARS-CoV ORF8, we demonstrate that expression of 8b and 8ab enables the corresponding recombinant viruses to partially overcome the inhibitory actions of IFN activation to achieve higher replication efficiencies in cells. We also found that proteins 8b and 8ab could physically interact with IRF3. Overexpression of 8b and 8ab resulted in the reduction of poly (I:C)-induced IRF3 dimerization and inhibition of the IFN-β signaling pathway. This counteracting effect was partially mediated by protein 8b/8ab-induced degradation of IRF3 in a ubiquitin-proteasome-dependent manner. Taken together, we propose that SARS-CoV may exploit the unique functions of proteins 8b and 8ab as novel mechanisms to overcome the effect of IFN response during virus infection.

Irritable bowel syndrome (IBS) and Functional Abdominal Pain (FAP) are among the most commonly reported Functional Gastrointestinal Disorders. Both have been associated with varying autonomic dysregulation. Heart Rate Variability Biofeedback (HRVB) has recently begun to show efficacy in the treatment of both IBS and FAP. The purpose of this multiple clinical replication series was to analyze the clinical outcomes of utilizing HRVB in a clinical setting. Archival data of twenty-seven consecutive pediatric outpatients diagnosed with IBS or FAP who received HRVB were analyzed. Clinical outcomes were self-report and categorized as full or remission with patient satisfaction, or no improvement. Qualitative reports of patient experiences were also noted. Full remission was achieved by 69.2 % and partial remission was achieved by 30.8 % of IBS patients. Full remission was achieved by 63.6 % and partial remission was achieved by 36.4 % of FAP patients. No patients in either group did not improve to a level of patient satisfaction or >50 %. Patient's commonly reported feeling validated in their discomfort as a result of psychophysiological education. Results suggest that HRVB is a promising intervention for pediatric outpatients with IBS or FAP. Randomized controlled trials are necessary to accurately determine clinical efficacy of HRVB in the treatment of IBS and FAP.

Cystinosis, a main cause of Fanconi syndrome, is reproduced in congenic C57BL/6 cystinosin knockout (KO) mice. To identify the sequence of pathogenic and adaptation mechanisms of nephropathic cystinosis, we defined the onset of Fanconi syndrome in KO mice between 3 and 6 months of age and analyzed the correlation with structural and functional changes in proximal tubular cells (PTCs), with focus on endocytosis of ultrafiltrated disulfide-rich proteins as a key source of cystine. Despite considerable variation between mice at the same age, typical event sequences were delineated. At the cellular level, amorphous lysosomal inclusions preceded cystine crystals and eventual atrophy without crystals. At the nephron level, lesions started at the glomerulotubular junction and then extended distally. In situ hybridization and immunofluorescence revealed progressive loss of expression of megalin, cubilin, sodium-glucose cotransporter 2, and type IIa sodium-dependent phosphate cotransporter, suggesting apical dedifferentiation accounting for Fanconi syndrome before atrophy. Injection of labeled proteins revealed that defective endocytosis in S1 PTCs led to partial compensatory uptake by S3 PTCs, suggesting displacement of endocytic load and injury by disulfide-rich cargo. Increased PTC apoptosis allowed luminal shedding of cystine crystals and was partially compensated for by tubular proliferation. We conclude that lysosomal storage triggered by soluble cystine accumulation induces apical PTC dedifferentiation, which causes transfer of the harmful load of disulfide-rich proteins to more distal cells, possibly explaining longitudinal progression of swan-neck lesions. Furthermore, our results suggest that subsequent adaptation mechanisms include lysosomal clearance of free and crystalline cystine into urine and ongoing tissue repair.

Context: Hutchinson-Gilford progeria syndrome (HGPS) and mandibuloacral dysplasia are well-recognized allelic autosomal dominant and recessive progeroid disorders, respectively, due to mutations in lamin A/C (LMNA) gene. Heterozygous LMNA mutations have also been reported in a small number of patients with a less well-characterized atypical progeroid syndrome (APS). Objective: The objective of the study was to investigate the underlying genetic and molecular basis of the phenotype of patients presenting with APS. Results: We report 11 patients with APS from nine families, many with novel heterozygous missense LMNA mutations, such as, P4R, E111K, D136H, E159K, and C588R. These and previously reported patients now reveal a spectrum of clinical features including progeroid manifestations such as short stature, beaked nose, premature graying, partial alopecia, high-pitched voice, skin atrophy over the hands and feet, partial and generalized lipodystrophy with metabolic complications, and skeletal anomalies such as mandibular hypoplasia and mild acroosteolysis. Skin fibroblasts from these patients when assessed for lamin A/C expression using epifluorescence microscopy revealed variable nuclear morphological abnormalities similar to those observed in patients with HGPS. However, these nuclear abnormalities in APS patients could not be rescued with 48 h treatment with farnesyl transferase inhibitors, geranylgeranyl transferase inhibitors or trichostatin-A, a histone deacetylase inhibitor. Immunoblots of cell lysates from fibroblasts did not reveal prelamin A accumulation in any of these patients. Conclusions: APS patients have a few overlapping but some distinct clinical features as compared with HGPS and mandibuloacral dysplasia. The pathogenesis of clinical manifestations in APS patients seems not to be related to accumulation of mutant farnesylated prelamin A. PMID:19875478

New insights into the clinical management of partial epilepsies.

PubMed

Hirsch, E; de Saint-Martin, A; Arzimanoglou, A

2000-01-01

The diagnosis, treatment, and prognosis of seizure disorders depend on the correct identification of epileptic syndromes. Partial epilepsies are heterogeneous and can be divided into idiopathic, cryptogenic, and symptomatic epilepsies. The most common of the idiopathic localization-related epilepsies is benign epilepsy with rolandic or centrotemporal spikes (BECTS). Seizures remain rare and the use of antiepileptic drug (AED) treatment in all patients does not appear justified. Children who present with some of the electroclinical characteristics of BECTS may also display severe unusual neurologic, neuropsychological, or atypical symptoms. In some cases, carbamazepine has been implicated as a triggering factor. Primary reading epilepsy and idiopathic occipital lobe epilepsies with photosensitivity are examples of an overlap between idiopathic localization-related and generalized epilepsies and respond well to sodium valproate. Autosomal dominant nocturnal frontal lobe epilepsy and benign familial infantile convulsions are recently described syndromes, differing in several ways from classical idiopathic localization-related epileptic syndromes. In cryptogenic or symptomatic epilepsy, the topography of the epileptogenic zone might influence drug efficacy. An individualized approach to AED selection, tailored to each patient's needs, should be used. Resistance of seizures to antiepileptic therapy may be due to diagnostic and/or treatment error or may be the result of noncompliance. Increasing the dosage, discontinuation or replacement of a drug, or addition of a second drug is indicated in truly resistant cases. The use of more than two AEDs rarely optimizes seizure control, and in some cases reduction of treatment may improve seizure control while lessening side effects. EEG-video assessment of patients with refractory epilepsy is important. Indications for and timing of epilepsy surgery should be reconsidered. Surgical therapy should probably be used more often and earlier than it is at present.

Genetic defects of the Na+-K+-2Cl- (NKCC2) sodium potassium chloride co-transporter result in severe, prenatal-onset renal salt wasting accompanied by polyhydramnios, prematurity, and life-threatening hypovolemia of the neonate (antenatal Bartter syndrome or hyperprostaglandin E syndrome). Herein are described two brothers who presented with hyperuricemia, mild metabolic alkalosis, low serum potassium levels, and bilateral medullary nephrocalcinosis at the ages of 13 and 15 yr. Impaired function of sodium chloride reabsorption along the thick ascending limb of Henle's loop was deduced from a reduced increase in diuresis and urinary chloride excretion upon application of furosemide. Molecular genetic analysis revealed that the brothers were compound heterozygotes for mutations in the SLC12A1 gene coding for the NKCC2 co-transporter. Functional analysis of the mutated rat NKCC2 protein by tracer-flux assays after heterologous expression in Xenopus oocytes revealed significant residual transport activity of the NKCC2 p.F177Y mutant construct in contrast to no activity of the NKCC2-D918fs frameshift mutant construct. However, coexpression of the two mutants was not significantly different from that of NKCC2-F177Y alone or wild type. Membrane expression of NKCC2-F177Y as determined by luminometric surface quantification was not significantly different from wild-type protein, pointing to an intrinsic partial transport defect caused by the p.F177Y mutation. The partial function of NKCC2-F177Y, which is not negatively affected by NKCC2-D918fs, therefore explains a mild and late-onset phenotype and for the first time establishes a mild phenotype-associated SLC12A1 gene mutation.

The analysis of the androgen receptor (AR) gene, mRNA, and protein in a subject with X-linked Reifenstein syndrome (partial androgen insensitivity) is reported. The presence of two mature AR transcripts in genital skin fibroblasts of the patient is established, and, by reverse transcriptase-PCR and RNase transcription analysis, the wild-type transcript and a transcript in which exon 3 sequences are absent without disruption of the translational reading frame are identified. Sequencing and hybridization analysis show a deletion of >6 kb in intron 2 of the human AR gene, starting 18 bp upstream of exon 3. The deletion includes the putative branch-pointmore » sequence (BPS) but not the acceptor splice site on the intron 2/exon 3 boundary. The deletion of the putative intron 2 BPS results in 90% inhibition of wild-type splicing. The mutant transcript encodes an AR protein lacking the second zinc finger of the DNA-binding domain. Western/immunoblotting analysis is used to show that the mutant AR protein is expressed in genital skin fibroblasts of the patient. The residual 10% wild-type transcript can be the result of the use of a cryptic BPS located 63 bp upstream of the intron 2/exon 3 boundary of the mutant AR gene. The mutated AR protein has no transcription-activating potential and does not influence the transactivating properties of the wild-type AR, as tested in cotransfection studies. It is concluded that the partial androgen-insensitivity syndrome of this patient is the consequence of the limited amount of wild-type AR protein expressed in androgen target cells, resulting from the deletion of the intron 2 putative BPS. 42 refs., 6 figs., 1 tab.« less

Background The prevalence and characteristics of fetal alcohol syndrome (FAS) and partial FAS (PFAS) in the United States (US) are not well known. Methods This active case ascertainment study in a Rocky Mountain Region City assessed the prevalence and traits of children with FAS and PFAS and linked them to maternal risk factors. Diagnoses made by expert clinical dysmorphologists in multidisciplinary case conferences utilized all components of the study: dysmorphology and physical growth; neurobehavior; and maternal risk interviews. Results Direct parental (active) consent was obtained for 1,278 children. Averages for key physical diagnostic traits and several other minor anomalies were significantly different among FAS, PFAS, and randomly-selected, normal controls. Cognitive tests and behavioral checklists discriminated the diagnostic groups from controls on 12 of 14 instruments. Mothers of children with FAS and PFAS were significantly lower in educational attainment, shorter, later in pregnancy recognition, and suffered more depression, and used marijuana and methamphetamine during their pregnancy. Most pre-pregnancy and pregnancy drinking measures were worse for mothers of FAS and PFAS. Excluding a significant difference in simply admitting drinking during the index pregnancy (FAS and PFAS = 75% vs. 39.4% for controls), most quantitative intergroup differences merely approached significance. This community’s prevalence of FAS is 2.9 to 7.5 per 1,000, PFAS is 7.9 to 17.7 per 1,000, and combined prevalence is 10.9 to 25.2 per 1,000 or 1.1% to 2.5%. Conclusions Comprehensive, active case ascertainment methods produced rates of FAS and PFAS higher than predicted by long-standing, popular estimates. PMID:26321671

Sad fetus syndrome comprising of a live twin gestation with a hydatidiform mole is a rare entity. The condition is even rarer when the co-existing live fetus is associated with a partial mole than a complete mole. We report the case of a 24-year-old G2P1L1 at 28 weeks gestation who presented to our casualty in the second stage of labour. She had a previous ultrasound scan at 13 weeks which showed a live fetus with a focal area of multicystic placenta. She delivered an alive preterm male fetus weighing 1.32 kg vaginally. Following expulsion of normal placenta of the live fetus, partial mole was expelled. The fetus was admitted to neonatal ICU and discharged after two weeks. Soon after delivery, β-hCG (human chorionic gonadotropin) was 1,21,993 mIU/ml which decreased to 30mIU/ml within two weeks. The patient was discharged with advice of regular follow up of β-hCG reports.

Pediatric developmental syndromes present with systemic, complex, and often overlapping clinical features that are not infrequently a consequence of Mendelian inheritance of mutations in genes involved in DNA methylation, establishment of histone modifications, and chromatin remodeling (the "epigenetic machinery"). The mechanistic cross-talk between histone modification and DNA methylation suggests that these syndromes might be expected to display specific DNA methylation signatures that are a reflection of those primary errors associated with chromatin dysregulation. Given the interrelated functions of these chromatin regulatory proteins, we sought to identify DNA methylation epi-signatures that could provide syndrome-specific biomarkers to complement standard clinical diagnostics. In the present study, we examined peripheral blood samples from a large cohort of individuals encompassing 14 Mendelian disorders displaying mutations in the genes encoding proteins of the epigenetic machinery. We demonstrated that specific but partially overlapping DNA methylation signatures are associated with many of these conditions. The degree of overlap among these epi-signatures is minimal, further suggesting that, consistent with the initial event, the downstream changes are unique to every syndrome. In addition, by combining these epi-signatures, we have demonstrated that a machine learning tool can be built to concurrently screen for multiple syndromes with high sensitivity and specificity, and we highlight the utility of this tool in solving ambiguous case subjects presenting with variants of unknown significance, along with its ability to generate accurate predictions for subjects presenting with the overlapping clinical and molecular features associated with the disruption of the epigenetic machinery.

One gene - many endocrine and metabolic syndromes: PTEN-opathies and precision medicine.

PubMed

Yehia, Lamis; Eng, Charis

2018-05-23

An average of 10% of all cancers (range 1-40%) are caused by heritable mutations and over the years, have become powerful models for precision medicine practice. Furthermore, such cancer predisposition genes for seemingly rare syndromes have turned out to help explain mechanisms of sporadic carcinogenesis and often inform normal development. The tumor suppressor PTEN encodes a ubiquitously expressed phosphatase that counteracts the PI3K/AKT/mTOR cascade - one of the most critical growth-promoting signaling pathways. Clinically, individuals with germline PTEN mutations have diverse phenotypes and fall under the umbrella term PTEN hamartoma tumor syndrome (PHTS). PHTS encompasses four clinically distinct allelic overgrowth syndromes, namely Cowden, Bannayan-Riley-Ruvalcaba, Proteus, and Proteus-like syndromes. Relatedly, mutations in other genes encoding components of the PI3K/AKT/mTOR pathway downstream of PTEN also predispose patients to partially overlapping clinical manifestations, with similar effects as PTEN malfunction. We refer to these syndromes as "PTEN-opathies." As a tumor suppressor and key regulator of normal development, PTEN dysfunction can cause a spectrum of phenotypes including benign overgrowths, malignancies, metabolic, and neurodevelopmental disorders. Relevant to clinical practice, the identification of PTEN mutations in patients not only establishes a PHTS molecular diagnosis, but also informs on more accurate cancer risk assessment and medical management of those patients and affected family members. Importantly, timely diagnosis is key, as early recognition allows for preventative measures such as high-risk screening and surveillance even prior to cancer onset. This review highlights the translational impact that the discovery of PTEN has had on the diagnosis, management, and treatment of PHTS.

Turner syndrome occurs in phenotypic females with complete or partial absence of X chromosome. The leading symptom is short stature, while numerous but mild stigmata manifest in the craniofacial region. These patients are commonly treated with growth hormone to improve their final height. The aim of this study was to assess the influence of long-term growth hormone therapy on craniofacial morphology in Turner syndrome patients. In this cross-sectional study cephalometric analysis was performed on 13 lateral cephalograms of patients with 45,X karyotype and the average age of 17.3 years, who have received growth hormone for at least two years. The control group consisted of 13 Turner syndrome patients naive to growth hormone treatment, matched to study group by age and karyotype. Sixteen linear and angular measurements were obtained from standard lateral cephalograms. Standard deviation scores were calculated in order to evaluate influence of growth hormone therapy on craniofacial components. In Turner syndrome patients treated with growth hormone most of linear measurements were significantly larger compared to untreated patients. Growth hormone therapy mainly influenced posterior face height, mandibular ramus height, total mandibular length, anterior face height and maxillary length. While the increase in linear measurements was evident, angular measurements and facial height ratio did not show statistically significant difference. Acromegalic features were not found. Long-term growth hormone therapy has positive influence on craniofacial development in Turner syndrome patients, with the greatest impact on posterior facial height and mandibular ramus. However, it could not compensate X chromosome deficiency and normalize craniofacial features. Copyright © 2016 Elsevier Ltd. All rights reserved.

Injuries from lightning and electrical injuries involve multiple systems of the body, however neurological symptoms are very widely reported. A disabling neuropsychological syndrome is also noted. This paper presents a comprehensive review of neurological and neuropsychological symptoms. Partial theories of causation for these injuries have been advanced, however, there is no convincing explanation for both delay in onset of symptoms and also the genesis of the neuropsychological syndrome. A theory of causation is proposed which satisfies both these constraints. This theory suggests circulating hormones such as cortisol, together with nitric oxide and oxidant free radicals from glutamatergic hyper-stimulation, act on tissues remote from the injury path including the hippocampus. This theory opens a research path to explore treatment options. PMID:28616016

We report a case of anomalous origin of the left anterior descending coronary artery (LAD) from the main pulmonary artery in a child with hypoplastic left heart syndrome (mitral atresia/aortic atresia). Mechanical circulatory support was necessary because of the inability to wean from cardiopulmonary bypass after the Norwood procedure. The patient died at 4 months of age having continued depressed right ventricular function. The diagnosis was made during a catheterization performed 6 weeks after surgery because of concern for stenosis of Blalock-Taussig shunt. We believe his prolonged postoperative recovery and eventual demise can partially be attributed to lack of cardioplegia to the anomalous LAD territory during surgery.

Idiopathic aplastic anemia (AA) is a rare hematological complication of Down syndrome (DS). The safety and efficacy of immunosuppressive therapy (IST) in individuals with DS remain unknown. We used a standard regimen of IST, comprising antithymocyte globulin and cyclosporine A, to treat three children with DS and idiopathic acquired AA. Two patients achieved a hematological (complete or partial) response and became transfusion independent at the final follow-up. The third patient failed to respond to IST and underwent bone marrow transplantation from a human leukocyte antigen (HLA)-mismatched unrelated donor. None of the patients experienced severe or unexpected adverse events during IST. Our experience suggests that IST is a safe and reasonable treatment, even in individuals with DS who suffer from AA and lack an HLA-matched sibling donor.

We report two patients with velo−cardio−facial syndrome (VCFS) who were admitted to our pediatric endocrinology clinic because of short stature and followed longitudinally until attainment of final height. Both patients followed a growth pattern consistent with constitutional delay of puberty with normal and near normal final height. Case 2 also had partial growth hormone (GH) deficiency and severe short stature (height SDS −3.4 SDS), but showed spontaneous catch−up and ended up with a final height of −2 SDS. These cases suggest that short stature in children with VCFS is due to a pattern of growth similar to that observed in constitutional delay of growth and puberty. Conflict of interest:None declared.

High seroprevalence of Middle East respiratory syndrome corona virus (MERS-CoV) in dromedary camels has been previously reported in United Arab Emirates (UAE). However, the molecular detection of the virus has never been reported before in UAE. Of the 7,803 nasal swabs tested in the epidemiological survey, MERS-CoV nucleic acid was detected by real-time PCR in a total of 126 (1.6 %) camels. Positive camels were detected at the borders with Saudi Arabia and Oman and in camels' slaughter houses. MERS-CoV partial sequences obtained from UAE camels were clustering with human- and camel-derived MERS-CoV sequences in the same geographic area. Results provide further evidence of MERS-CoV zoonosis.

A practical approach to the prevention of miscarriage: part 5--antiphospholipid syndrome as a cause of spontaneous abortion.

To describe the diagnosis and treatment of antiphospholipid syndrome as it relates to spontaneous abortion. The relative importance of performing tests of antiphospholipid antibodies that prolong the partial thromboplastin time and other autoantibodies against phospholipids measured by ELISA are discussed. The most important diagnostic tests are the lupus anticoagulant, anticardiolipin antibody and antiphosphatidyl serine. Low molecular weight heparin and low dose aspirin are the two most important therapies. Women with recurrent miscarriages or even an unexplained miscarriage especially after ten weeks (but sometimes even early first trimester) or a history of thrombosis or intrauterine growth restriction and maybe preeclampsia are candidates for anticoagulant therapy, especially with the presence of significant levels of the lupus anticoagulant or anticardiolipin or antiphosphatidyl serine antibodies (> 40 pl units/ml).

The Dandy-Walker syndrome (DWS) is a hereditary disorder, appearing somewhat more frequently in women. The most important characteristics of the DWS are the lack of the cerebellar vermis, varying from a partial lack to a complete agenesis, and enlargement of the cerebrospinal spaces, especially in the fourth ventricle. The above mentioned morphological changes clinically manifest in ataxia, increased intracranial pressure and hydrocephalus. Here is presented a family with DWS, where the disease is contracted only by female members, in two generations, whereas no signs of DWS have been noticed in male family members. DWS is clinically manifested from early childhood to middle age, with the morphological changes varying from hypoplastic cerebellar vermis to widening of the brain ventricles and hydrocephalus and arachnoid cyst in the occipital part.

Twin-twin transfusion syndrome (TTTS) and twin anemia polycythemia sequence (TAPS) are severe complications in monochorionic twin pregnancies associated with high mortality and morbidity risk if left untreated. Both diseases result from imbalanced inter-twin blood transfusion through placental vascular anastomoses. This review focuses on the differences in antenatal management between TTTS and TAPS. Expert commentary: The optimal management for TTTS is fetoscopic laser coagulation of the vascular anastomoses, preferably using the Solomon technique in which the whole vascular equator is coagulated. The Solomon technique is associated with a reduction of residual anastomosis and a reduction in post-operative complications. The optimal management for TAPS is not clear and includes expectant management, intra-uterine transfusion with or without partial exchange transfusion and fetoscopic laser surgery.

Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of lymphocyte apoptosis. Children present with chronic nonmalignant lymphadenopathy, hepatosplenomegaly, and autoimmune cytopenias. Recent advances show efficacy of treatment with immunosuppressive drugs. Sirolimus, an mammalian target of rapamycin inhibitor, improves autoimmune cytopenias and lymphoproliferation, with a safe profile. We present 2 patients, a 5-year-old girl and 15-year-old boy, diagnosed with ALPS with initial partial response to steroid treatment. Autoimmune cytopenias and lymphoproliferation then became refractory to treatment, with recurrence of symptoms. In both cases, treatment with sirolimus was started, with a rapid response, complete remission of cytopenias, and resolution of lymphoproliferation, with no significant adverse effects. sirolimus is an effective and safe drug for controlling children with cytopenias and lymphoproliferation linked to ALPS.

Computer-assisted tomography (CT) with 2 mm axial sections and reconstructions was carried out in 31 children affected by GH deficiency (GHD): 18 with idiopathic complete isolated GHD, 3 with idiopathic partial isolated GHD, 2 with idiopathic panhypopituitarism, 4 with isolated acquired GHD and 4 with acquired panhypopituitarism. Density in the intrasellar area on CT corresponded to that of cerebrospinal fluid in 13/20 cases with idiopathic hypopituitarism and in 2/8 cases with acquired hypopituitarism. The overall incidence of primary empty sella syndrome (PESS) in the GH deficient patients studied was thus over 48%, while in children without endocrine dysfunction, it was only 5/213 (2.4%). It is concluded that PESS is more frequent in childhood than assumed until now and that it is frequently associated with GHD.

Clinical history and inappropriate insulin secretion during hypoglycemic episodes permit the diagnosis of hyperinsulinism. We report 2 cases of factitious hyperinsulinism leading to partial pancreatectomy. Case 1 was an 8-year-old girl who presented with severe hypoglycemia and elevated insulin and C-peptide levels. Catheterization of pancreatic veins was performed to localize the excess insulin secretion. Insulinoma was suspected, and partial pancreatectomy was performed. Ten days after surgery, severe hypoglycemia recurred with severely elevated plasma insulin levels (x100) but very low C-peptide plasma levels, suggesting factitious hyperinsulinemia. Hypoglycemic episodes before surgery were provoked by oral sulfonamides; postoperative episodes were caused by parenteral insulin. Falsified prescriptions for sulfonamides and insulin by the mother, a nurse, were found. Case 2 was a 6-month-old girl who presented with seizures and hypoglycemia but had a symptom-free interval of many months afterward. At 2 years of age, repeated hypoglycemic seizures and elevated insulin plasma levels suggested congenital hyperinsulinism. C-peptide plasma level, measured once, was normal, but blood sampling was performed 15 minutes after a hypoglycemic episode. Partial pancreatectomy was performed. Two weeks after surgery, hypoglycemic seizures recurred, and the patient was admitted for pancreatic vein catheterization. This investigation was performed during hypoglycemia and revealed high insulin levels and undetectable C-peptide levels, suggesting factitious hypoglycemia. Insulin/C-peptide ratio analysis is crucial to assess factitious hypoglycemia, although sulfonamide-induced hypoglycemia is not thereby detected. One percent (2 of 250) of all cases of hyperinsulinemic hypoglycemia in our unit have been identified as Munchausen syndrome by proxy. Atypical disease history should raise the question of factitious hypoglycemia.

Cryopyrin-associated periodic syndromes (CAPS) are a group of chronic, relapsing autoinflammatory disorders which may be complicated by systemic AA amyloidosis. The aim of our study was to evaluate serum amyloid protein A (SAA) level in CAPS patients treated with Interleukin-1beta (IL-1β) antagonist and to correlate its level with treatment response. All patients of CAPS Italian Register treated with IL-1β inhibitor were enrolled. SAA levels before starting therapy, and at last visit were evaluated. Patients were then divided in complete responders and partial responders. Twenty-five patients were enrolled. SAA level before starting therapy was increased (median 118.5 mg/L, IQR 96.4-252.8; normal value <6.4 mg/L), while at last visit SAA was significantly reduced (median 4.3 mg/L, IQR 2.3-12.7) (p<0.001). However 12 patients still presented SAA levels beyond normal range, 10/25 patients (40%) showed a complete response to treatment. Conversely, 15 patients presented only a partial response, of which 12 for increased SAA value and 3 for increased CRP value. Patients with partial response had SAA values significantly higher than patients with complete response (median 12.6 mg/L; IQR 8.3-20.0 vs. 2.7 mg/L; IQR 1.6-4.1, p<0.001). Our results confirm the long term efficacy of anti IL-1β treatment in CAPS and the decrease of SAA levels; however 48% of patients still presented SAA elevation despite treatment. The real risk of these patients in developing amyloidosis is not clear but the persistent increase of SAA needs a close follow-up.
