A Comprehensive Guide to Paget’s Disease of Bone

PDB is a long-standing pathological stateillustrated by aberrant bone remodeling and metabolism arising in structural anomalies of the bone tissue. While this disease may remain asymptomatic, mild symptoms such as joint and bone discomfort may be present. However, an early warning sign is intense nocturnal bone pain. Moreover, PDB may result in complications such as deafness, fractures, compression of cranial nerves or the spinal cord, and hydrocephalus. This disease is more frequently observed in individuals above the age of 50, affecting individuals of all races and ethnicities, with a slightly higher prevalence in males. Diagnosis of PDB involves comprehensive clinical assessment, patient history, and specialized tests. Pharmacological treatments such as bisphosphonates, calcitonin, and surgical intervention may be employed to manage the disease. Supplementation is essential to prevent hypocalcemia. PDB may lead to rare complications, including sarcomatous conversion of the pagetic lesion and high-output congestive heart failure which concerns healthcare professionals.

Prenatal features of aneurysm of the posterior cerebral artery: a case report

BackgroundFetal cerebral aneurysm other than aneurysm of vein of Galen aneurysmal malformation (VGAM) is extremely rare. This report describes prenatal features of aneurysm of the posterior cerebral artery (APCA) with rapid progression and its natural intrauterine course of the disease, which has never been reported.Case presentationThis is the first report of prenatal features of APCA, detected at 34–36 weeks of gestation, simulating choroid plexus cyst or arachnoid cyst. The diagnosis was based on color flow ultrasound with tracing along the course of cerebral arteries. Also, rendered 3D color flow ultrasound was helpful in demonstrating course of the vessels feeding the aneurysm and supporting the diagnosis. The aneurysm showed nature of rapidly progressive changes, leading to leakage resulting in intracerebral and intraventricular hemorrhage as well as high output state associated with anemia. Prenatal diagnosis and management are very challenging. This case ended up with planned delivery at 37 weeks, giving birth to a surviving male newborn, weighing 2600 g. The neonatal CT brain scans and CTA confirmed the prenatal findings. The prognosis was relatively poor because of extensive intracerebral hemorrhage with severe hydrocephalus and brain midline shift. The couple opted for neonatal palliative care without neurosurgical correction.ConclusionThis study demonstrate that the most important tool for prenatal diagnosis is color Doppler ultrasound, which will demonstrate turbulent blood flow. Three-dimension color Doppler ultrasound is helpful in supporting the diagnosis. The case presented here suggests that the disease has a natural course of rapid progression and massive brain destruction or high output congestive heart failure can be expected.

Efficacy of intravenous propranolol for life‐threatening diffuse neonatal hemangiomatosis

Oral propranolol is recommended as the first-line agent for infantile hemangioma requiring systemic treatment. Life-threatening complications such as obstructive infantile hemangioma of the airway or infantile hepatic hemangioma associated with high-output congestive heart failure are major indications for the consideration of early treatment. We present the case of an infant with life-threatening diffuse neonatal hemangiomatosis, including airway obstruction due to subglottic hemangioma, heart failure due to multiple hepatic hemangiomas with portohepatic venous shunts, and severe anemia due to continuous gastrointestinal bleeding, in which treatment with intravenous propranolol proved successful.

FETAL HEPATIC HEMANGIOMA: A CASE REPORT

Fetal liver tumors represent approximately 5% of all congenital tumors and hemangiomas account for approximately 15% of all fetal liver tumors. Hem­angioma and hemangioendothelioma are benign vascular tumors but they are associated with a significant morbidity and mortality due to high output congestive heart failure and arteriovenous shunting. Ultrasound features of hepatic hemangioma can overlap with arteriovenous malformation. This is a case report of fetal hepatic hemangioma with aretriovenous shunting de­tected on routine anomaly scan at 20 weeks of gestation in 22 years old Nep­alese women who was asymptomatic. Prenatally, a 3.2cm x 2.8cm multicystic mass was seen in the left hypochondrium of the fetal abdomen displacing the stomach. On color Doppler examination, the mass showed internal color flow and multiple tortuous dilated vessels noted around the lesion. After counsel­ing regarding the lesion to the mother and her family; decision to abort the fetus was made. Autopsy was done for the final diagnosis of the lesion, which showed vascular mass in the left lobe of liver insinuating between stomach and spleen.

An Unusual Case of Thiamine Deficiency in a Total Parenteral Nutrition-Dependent Child Secondary to Munchausen by Proxy

An Unusual Case of Thiamine Deficiency in a Total Parenteral Nutrition-Dependent Child Secondary to Munchausen by Proxy

High-flow arteriovenous fistula is not associated with increased extracellular volume or right ventricular dysfunction in haemodialysis patients.

High-output congestive heart failure secondary to high-flow arteriovenous fistula (AVF) has been reported in haemodialysis (HD) patients. As high-flow AVF (HFA) would be expected to result in fluid retention, we conducted an observational study to characterize the relationship between AVF flow (Qa) and extracellular water (ECW) in HD patients. We measured Qa by ultrasound dilution in prevalent HD outpatients with an AVF in two dialysis centres. The ECW:total body water (TBW) ratio was measured both pre- and post-dialysis by multifrequency bioimpedance analysis. Transthoracic echocardiograms (TTEs) were performed as part of routine clinical management. We included 140 patients, mean age 62.7 ± 15.7 years, 60.7% male, 47.9% diabetic and 22.9% with coronary revascularization. Mean Qa was 1339 ± 761 mL/min and 22 (15.7%) patients had HFA defined as Qa >2.0 L/min. Qa was positively associated with an upper arm AVF (P = 0.005), body mass index (P = 0.012) and N-terminal pro-brain natriuretic peptide (NT-proBNP) (P = 0.047) and negatively associated with diabetes (P < 0.001) and coronary revascularization (P = 0.005). The ECW:TBW ratio was positively associated with age (P < 0.001), Davies comorbidity index (P = 0.034), peripheral vascular disease (P = 0.030) and NT-proBNP (P = 0.002) and negatively associated with serum albumin (P < 0.001). Qa was not associated with the ECW:TBW ratio (P = 0.744). TTE parameters were not associated with Qa. In our outpatient HD cohort, high AVF flow was not associated with ECW expansion, either pre- or post-dialysis when accounting for potential confounders. By controlling ECW, high access flow should not necessarily be perceived as a threat to cardiovascular physiology.

P1261DIAGNOSTIC VALUE OF TEMPORARY OCCLUSION OF ARTERIO-VENOUS HIGH FLOW FISTULA DURING RIGHT HEART CATHETERISATION IN PATIENTS WITH PULMONARY HYPERTENSION

Abstract Background and Aims Pulmonary hypertension (PH) is prevalent in patients with functioning high-flow arterio-venous fistula (HFAVF) and associated with congestive heart failure (CHF). The real incidence and possible causes of this phenomenon is a matter of debate. Hemodynamic effects of HFAVF is considering as one of the reasons for PH formation. The subject of study was the impact of HFAVF on selected parameters of central hemodynamics. In particular, the diagnostic relevance of test of temporary HFAVF occlusion (TTO) was evaluated during right heart catheterization (RHC). Method A total of 13 patients were enrolled: 8 - after kidney transplantation (KT) with preserved allograft function and 5 - on maintenance hemodialysis (HD). All of them demonstrated clinical presentation of CHF III-IV class (NYHA). Severe PH and diastolic disfunction (DD) were observed at a baseline: echocardiographic systolic pulmonary arterial pressure sPAP (mmHg): M=59 (SD 13), ratio of mitral early diastolic inflow velocity (E) (pulsed wave Doppler) to average of septal and lateral mitral annular early-diastolic peak velocity (e′) (tissue Doppler imaging) E/e′ M=18 (SD 5). The ones who have comorbid conditions that cause PH were excluded. All patients bore an upper arm HFAVF, flow of the AVF (Qa) measured by Doppler ultrasonography was markedly high (Qa): M = 3,8 l/min (SD 1,2), the cardio-pulmonary recirculation (Qa/CO): M = 51% (SD 13). All patients underwent RHC and TTO AVF. Echocardiography (Echo) was performed initially and on the follow up (8 weeks after AVF closure/flow reduction). Statistical analysis was performed using the STATISTICA 13 software (Wilcoxon, T-test). Results The results of RHC and Echo data are presented in tables 1, 2. As can be seen from the table data, all cases demonstrated instrumental features of high output CHF (HO CHF) in accordance with patient’s clinical status. TTO of HFAVF resulted in statistically significant decrease in CO and CI values, but no changes in PAP parameters were observed. Taking into account clinical and instrumental features of advanced CHF, HF AVF was closed in 8 patients after KT and in 2 patients on HD. 3 patients on HD underwent AVF flow reduction up to Qa not exceeding 1,1 l/min. Follow-up demonstrated complete resolution of CHF and dramatic improvement of DD, reduction in CO, CI, sPAP, volume parameters. CO, cardiac output; CI, cardiac index; sPAP, systolic pulmonary arterial pressure; meanPAP, mean pulmonary arterial pressure; RAP, mean right atrial pressure; PCWP, pulmonary capillary wedge pressure; LV EDVi, left ventricular end-diastolic volume index; LAVi, left atrial volume index; RAVi, right atrial volume index; Conclusion PH is a component of AVF-induced HO CHF and could be classified as postcapillary one. TTO confirms significant HFAVF contribution to specific changes of parameters of central hemodynamics due to HO CHF. TTO does not impact on PAP values and therefore is not valid to clarify PH genesis per se.

Coronary Vasospasm-Induced Myocardial Infarction: An Uncommon Presentation of Unrecognized Hyperthyroidism

Hyperthyroidism can present with cardiac issues, such as tachycardia, atrial fibrillation, and high output congestive heart failure. Rare case reports of coronary vasospasm leading to myocardial infarction (MI) are published. Of these cases, many are known to be hyperthyroid prior to cardiac presentation. We report a female patient with unrecognized thyrotoxicosis who presents with acute MI secondary to coronary vasospasm. J Med Cases. 2020;11(5):140-141 doi: https://doi.org/10.14740/jmc3473

Early echocardiographic modifications after flow reduction by proximal radial artery ligation in patients with high-output heart failure due to high-flow forearm arteriovenous fistula.

Arteriovenous fistula (AVF) for haemodialysis (HD) induces a volume/pressure overload which impairs bi-ventricular function and increases systolic pulmonary arterial pressure (PAPS) and left ventricular mass (LVM). In the presence of high blood flow (Qa) AVF (> 1.5 L/min/1.73 m2) and cardio-pulmonary recirculation (>20%), high-output congestive heart failure (CHF) may occur and AVF flow reduction is recommended. Proximal Radial Artery Ligation (PRAL) is an effective technique for distal radio-cephalic (RC) AVF flow reduction. we evaluated six HD and four transplant patients with high-flow RC AVF and symptoms of CHF who underwent PRAL. We compared echocardiographic (ECHO) findings before (T0) and 1 and 6 months (T1,T6) after PRAL. Preoperative ECHO was performed before (T0b) and after AVF anastomosis manual compression (T0c). At T1 AVF flow reduction rate was 58.4% ± 13% and 80% of patients reported improved CHF symptoms. ECHO data showed an improvement of tricuspid annular plane systolic excursion (TAPSE) at T1 (p = 0.03) and a reduction of PAPS at T6 (p = 0.04). TAPSE improved after AVF anastomosis compression during preoperative ECHO (p = 0.03). Delta of TAPSE at the dynamic manoeuvre at T0 directly correlated with early (1 month after PRAL, p = 0.01) and late (6 months after PRAL, p = 0.04) deltas of TAPSE. AVF flow reduction after PRAL induces immediate regression of CHF symptoms, early improvement of TAPSE and late improvement of PAPS, suggesting a prevalent right sections involvement in CHF. Preoperative TAPSE modification after AVF anastomosis compression could represent a useful evaluation tool to determine which patients would benefit of PRAL.

Fetal hepatic hemangioma: a case report

Fetal liver tumors represent approximately 5% of all congenital tumors and hemangiomas account for approximately 15% of all fetal liver tumors. Hemangioma and hemangioendothelioma are benign vascular tumors but they are associated with a significant morbidity and mortality due to high output congestive heart failure and arteriovenous shunting. Ultrasound features of hepatic hemangioma can overlap with arteriovenous malformation. This is a case report of fetal hepatic hemangioma with aretriovenous shunting detected on routine anomaly scan at 20 weeks of gestation in 22 years old Nepalese women who was asymptomatic. Prenatally, a 3.2cm x 2.8cm multicystic mass was seen in the left hypochondrium of the fetal abdomen displacing the stomach. On color Doppler examination, the mass showed internal color flow and multiple tortuous dilated vessels noted around the lesion. After counseling regarding the lesion to the mother and her family; decision to abort the fetus was made.

Increased Intra-abdominal Pressure Induces Acute Kidney Injury in an Experimental Model of Congestive Heart Failure

Congestive heart failure (CHF) entails a complex interaction between the heart and the kidney that represents a clinical entity called cardiorenal syndrome (CRS). One of the mechanisms underlying CRS includes increased intra-abdominal pressure (IAP). We examined the effect of elevated IAP on kidney function in rats with low- and high-output CHF. Rats with compensated and decompensated CHF induced by means of aortocaval fistula, rats with myocardial infraction (MI) induced by means of left anterior descending artery ligation, and sham control rats were subjected to either 10 or 14 mm Hg IAP. Urine flow (V), Na+ excretion (UNaV), glomerular filtration rate (GFR), and renal plasma flow (RPF) were determined. The effects of pretreatment with tadalafil (10 mg/kg orally for 4 days) on the adverse renal effects of IAP were examined in decompensated CHF and MI. Basal V and GFR were significantly lower in rats with decompensated CHF compared with sham control rats. Decompensated CHF rats and MI rats subjected to 10 and 14 mm Hg IAP exhibited more significant declines in V, UNaV, GFR and RPF than compensated and sham controls. Elevated IAP also induced tubular injury, as evidenced by significantly increased absolute urinary excretion of neutrophil gelatinase-associated lipocalin. In addition, in a nonquantitative histologic analysis, elevated IAP was associated with increase in necrosis and cell shedding to the tubule lumens, especially in the decompensated CHF subgroup. Pretreatment of decompensated CHF rats and MI rats with tadalafil ameliorated the adverse renal effects of high IAP. Elevated IAP contributes to kidney dysfunction in high- and low-cardiac output CHF. IAP induces both hemodynamic alterations and renal tubular dysfunction. These deleterious effects are potentially reversible and can be ameliorated with the use of phosphodiesterase-5 inhibition.

Abstract TP584: Higher Prevalence of Congestive Heart Failure (CHF) in Hereditary Hemorrhagic Telangiectasia (HHT) Secondary to Anemia and Artero-venous Malformations (AVMs)

Introduction: Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic disorder with vascular anomalies of various organ systems including the skin, brain, heart, lungs, and liver. While the most commonly recognized disease burden of HHT are epistaxis and mucocutaneous telangiectasia, the development of vascular malformations can result in more severe symptoms such as cerebral hemorrhage, liver cirrhosis, and stroke. Various case reports/series have reported high output cardiac failure, secondary to presence of a single large AVM or multi organ AVMs, as a major cause of morbidity and mortality in HHT population. To the best of our knowledge, this is the first study analyzing the cardiovascular disease burden in HHT patients from a large national database. Methodology: All HHT patients were identified using ICD-9 code 448.0 using the 2014 National Inpatient Sample (NIS) database. Comorbidities - intracerebral hemorrhage (431), cerebrovascular anomaly (747.81), congestive heart failure (428.0), anemia (285.9) were also identified using the ICD-9 coding system. Descriptive and inferential statistical analysis were performed using SAS 2015. Results: A total of 842 HHT patients were identified with relatively older patients having increased prevalence of anemia (29% vs 15%), congestive heart failure (16% vs 8%), intra-cerebral hemorrhage (0.5% vs 0.3%), hypertension (47% vs 42%) compared to general population, respectively. We report HHT to be linked with having higher odds (p &lt; 0.05) of congestive heart failure (1.6 times), chronic pulmonary lung disease (1.7 times), liver disease (3 times), anemia (1.6 times), cerebrovascular anomaly including cerebral AVMs (26 times), and other neurological disorders than patients without HHT, after adjusting for confounders. Conclusion: This is the first database study confirming higher prevalence of CHF in HHT. We infer that chronic anemia and AVM/AVF can cumulatively cause high output congestive heart failure causing increased morbidity and mortality in HHT population especially in advanced ages.

Management of fluid status and cardiovascular function in patients with diffuse skin inflammation

Background: Skin inflammation causes vasodilation and increased vascular permeability, which may result in decreased blood pressure and peripheral edema. Patients with erythroderma usually compensate for low blood pressure with fluid retention and increased cardiac output. However, if the heart cannot support increased cardiac output, blood pressure will stay low, resulting in severe compensatory fluid retention, which leads to decompensated congestive heart failure, and pulmonary edema. Treatment for high-output congestive heart failure focuses on the primary pathology, which is skin inflammation. However, aggressive treatment of the inflammation with glucocorticoids may result in rapid resorption of extravascular fluid into the intravascular space and occurrence or aggravation of pulmonary edema. Erythrodermic patients with no clinical heart failure are also at risk for developing pulmonary edema if they receive glucocorticoids and/or intravascular fluids. Most hospitalists and dermatologists are not familiar with fluid administration and ways to manage cardiovascular function and blood pressure in patients with skin inflammation.Objectives and methods: In this article, we discuss the pathophysiology of vascular and fluid changes in the context of diffuse skin inflammation and provide some basic guidelines that can be presented to hospitalists by dermatologists.Limitations: Most of the recommendations and guidelines in the article are based on basic science and on the personal experience of the authors and are not supported by controlled trials.Capsule summaryDiffuse skin inflammation causes major changes in the cardiovascular system and in the perfusion of internal organs.We provide guidelines for management of fluid status and cardiovascular function in patients with diffuse skin inflammation.Dermatologists can provide hospitalists or primary care providers with these guidelines to help them with creating better treatment plans.

A Severe Case of Aneurysmal Malformation of the Vein of Galen, Cardiac Failure and Intrauterine Fetal Death.

Aneurism of the vein of Galen is a rare congenital anomaly, where complex arteriovenous malformation are identified between multiple choroidal arteries and the median prosencephalic vein of Markowski, which is a precursor of the vein of Galen, with subsequent aneurysmal enlargement of the respective arteriovenous system. The congenital malformation develops during week 6 to 11 of fetal development. Infants often die from high-output congestive heart failure. We present a case of a 40 years old patient, presented the first time at hospital at 28 weeks of gestation for lower perception of fetal movements. The patient was referred to our Prenatal Diagnosis Unit for a suspected cardiac malformation. We diagnosed cardiomegaly along vein of Galen aneurysmal malformation (VGAM) with severe cardiac failure, ascites, and critical fetal distress. Fetal demise was noted 24 hours later, during the corticosteroid procedures for fetal maturation. A stillborn weighting 2000g with a severe hydropic aspect was born after labor induction. Autopsy was performed following injection of colored gelatin in carotid vessels. The aneurysmal defect was evident in the vein of Galen and straight sinus. We also found the transverse, sagittal and the occipital sinus seriously dilated. We could not highlight the communication with the middle cerebral artery, because of the degradation of the cerebral tissue, despite an optimal preparation

Thoracoscopic resection of an unusually hypervascular extra-lobar pulmonary sequestration that resembled an arteriovenous malformation in a 2-year-old boy

Abstract There is a risk for high-output congestive heart failure to be associated with an extra-lobar pulmonary sequestration (ELS) when there is left-to-left shunting caused by a large systemic arterial supply to a sequestration and venous drainage via the pulmonary veins into the left atrium. We present a 2-year-old boy who underwent thoracoscopic resection of an unusually hypervascular right ELS with a high output left-to-left shunt between the aorta and the left atrium via a pulmonary vein. This case is of particular interest because computed tomographic angiography identified a hypervascular nidus with indistinct borders between arterial and venous vessels suggestive of an arteriovenous malformation.

Infantile Hepatic Hemangioendothelioma: An Uncommon Cause of Persistent Pulmonary Hypertension in a Newborn Infant

Multifocal and diffuse infantile hepatic hemangioendotheliomas commonly present with signs of high-output congestive heart failure. In addition, prolonged persistent pulmonary overcirculation eventually leads to the development of pulmonary hypertension at a later age. We report a 2-day old, full-term infant with multifocal, large infantile hepatic hemangioendothelioma, who presented with an early onset of pulmonary hypertension, managed successfully with supportive care and systemic therapy directed toward the involution of infantile hepatic hemangioendothelioma.

Hemangiomas and β-Blockers: On the Rebound.

* Abbreviations: IH — : infantile hemangioma OP — : oral propranolol Infantile hemangioma (IH) is the most common tumor of childhood, and although most lesions eventually involute, the proliferative phase may be associated with complications, such as ulceration, bleeding, functional compromise, and anatomic disfigurement. Rarely, IH can have major or life-threatening consequences, such as airway obstruction, high-output congestive heart failure, and consumptive hypothyroidism. It is for reasons such as these that therapy may be indicated. Propranolol, a nonselective β-adrenergic receptor antagonist, has been used off-label in children for years in the treatment of cardiac dysrhythmias, congestive heart failure, and hypertension. In 2008, Leaute-Labreze et al1 reported their discovery of its benefits against IH, an observation confirmed in their follow-up report of 32 infants 1 year later.2 Oral propranolol (OP) has evolved to become the standard of care for IH therapy. In 2014, a pediatric formulation was approved by the US Food and Drug Administration (March) and the European Medicines Agency (April).3,4 The results of the multicenter, randomized, double-blind, adaptive phase 2-3 trial assessing its efficacy and safety in treating IH were published in 2015.5 Although the precise mechanisms of … Address correspondence to Anthony J.

Vein of Galen aneurysmal malformations (VGAM) are rare intracranial vascular anomalies typically found in children. The anatomic landmark of a VGAM is the presence of multiple arteriovenous shunts draining into a dilated median prosencephalic vein, an embryonic vessel normally absent at the adult stage. This article reviews the developmental anatomy, the clinical presentation, and the current management of VGAM. KEYWORDS: Aneurysmal malformations of the vein of Galen, Trans catheter embolization (TCE), cardiac failure. INTRODUCTION: The vein of Galen is located under the cerebral hemispheres and drains the anterior and central regions of the brain into the sinuses of the posterior cerebral fossa. The vein of Galen aneurysmal malformation is a choroidal type of arteriovenous malformation involving the vein of Galen forerunner and is distinct from an arteriovenous malformation with venous drainage into a dilated, but already formed, vein of Galen. 1 Aneurysmal malformations of the vein of Galen (VGAM) typically result in high-output congestive heart failure or may present with developmental delay, hydrocephalus, and seizures. MATERIALS AND METHODS: Here we present a case, a term male newborn appropriate for gestational age referred to us for respiratory distress, grunting and increased precordial activity and cardiac murmur. On extensive evaluation was found to have in MRI brain scan with Venogram revealed a huge vein of Galen aneurysm /malformation with multiple feeders (Choroidal in type). A brief review of literature is discussed.
