Case of Thoracic Spinal Stenosis Secondary to Paget＇s Disease

PAGET＇S disease, also called osteitis deformans, is a metabolic bone disorder. It is characterized by increased bone resorption and the compensatory formation of new bones. The increased bone conversion and remodeling lead to the incrustation of woven bones and lamellar bones and finally result in the expansion, loosening, and excessive vascularization of the affected bones, rendering them susceptible to deformity and fracture. Paget＇s disease occurs much more commonly in Anglo-Saxons than in Asians and Africans.     

Emphasis should be placed on the diagnosis and therapy of tumor induced osteomalacia

Phosphate plays a critical part in the regulation of cell metabolism,and phosphate homeostasis is closely regulated in normal humans.Chronic hypophosphatemia can cause abnormal mineralization of bone,increased alkaline phosphatase and,in the longer term,metabolic bone disease.Osteomalacia is the main metabolic bone disorder caused by chronic hypophosphatemia,which is characterized by inadequate or delayed mineralization of osteoid in mature cortical or spongy bone.     

Intra-cranial metastasis of gastrointestinal stromal tumor

With the evolution of immunochemical staining techniques and better imaging modalities with better image resolution and whole body coverage, gastrointestinal stromal tumor (GIST), the most common mesenchymal tumor of the gastrointestinal tract, is often encountered in clinical practice. Metastasis is common with malignant GIST and can be found in up to 50% of patients at presentation. Liver and peritoneum are the two most common sites of metastasis and accounted for 95% of cases. Lymphatics, bone and lung metastasis are rare. Malignant GIST with intracranial metastasis is even rarer, with only a few cases reported in the literature, and most of these had earlier metastasis elsewhere. Radiological features for GISTs are not specific but it does contribute to confirming early and accurate diagnosis of malignant GISTs by judging the tumor size, enhancement pattern and the invasion of adjacent structures. We report a case of a 26-year-old male with metastatic GIST to the liver and subsequently to the brain and skull vault. This is the first case reported in our locality and he is the youngest patient reported with this disease entity. The clinical progress, radiological features and the role of imaging will be discussed further in this paper. The radiological and clinical features of the primary tumor will specifically be addressed. The purpose of this paper is to enrich the current database of this rare disease entity and to alert both radiologists and clinicians about the imaging features of GIST with intracranial metastasis.

The value of ~(99m)Tc methylene diphosphonate bone scintigraphy in diagnosing relapsing polychondritis

Relapsing polychondritis (RP) is a recurrent disease involving cartilage mainly of the ear, nose, larynx, trachea, and bronchus. The typical manifestations of the disease in the ear and nose can be easily recognized, but the symptoms could be ignored or easily confused with those of other diseases when the cartilage of other sites is involved. Thus, it is necessary to develop a new technique for the diagnosis of this disease. Few cases of abnormal accumulation of radioactivity at cartilage shown by 99mTc methylene diphosphonate (MDP) bone scintigraphy are described in the literature. In this report, we present 4 patients of whom 3 had positive findings on 99mTc MDP bone scintigraphy with an assessment of 99mTc MDP bone scintigraphy in the diagnosis of RP.

Clinically, AD is slowly progressive, leading to memory loss; alteration of higher intellectual function and cog…     

Kidney disease in China: recent progress and prospects

Kidney disease is a worldwide public health problem.The prevalence of end-stage renal disease （ESRD）, a final outcome of kidney disease, has increased progressively in the past decades and has emerged as a great burden to the healthcare system in China. Glomerulonephritis is still the most common cause of ESRD in China. However, the prevalence of diabetes and hypertension are increasing dramatically. There are modifiable risk factors for the development of progressive renal dysfunction. The challenge is to identify the disease and deliver effective therapies at the right time with the right tools. In the last two years,     

Pathological characteristics of liver allografts from donation after brain death followed by cardiac death in pigs

Donation after brain death followed by circulatory death （DBCD） is a unique practice in China. The aim of this study was to define the pathologic characteristics of DBCD liver allografts in a porcine model. Fifteen male pigs （25-30 kg） were allocated randomly into donation after brain death （DBD）, donation after circulatory death （DCD） and DBCD groups. Brain death was induced by aug- menting intracranial pressure. Circulatory death was induced by withdrawal of life support in DBCD group and by venous injection of 40 mL 10% potassium chloride in DCD group. The donor livers were perfused in situ and kept in cold storage for 4 h. Liver tissue and common bile duct samples were col- lected for hematoxylin and eosin staining, TUNEL testing and electron microscopic examination. Spot necrosis was found in hepatic parenchyma of DBD and DBCD groups, while a large area of necrosis was shown in DCD group. The apoptosis rate of hepatocytes in DBD [（0.56±0.30）%] and DBCD [（0.50 ±0.11）%] groups was much lower than that in DCD group [（3.78±0.33）%] （P〈0.05）. And there was no significant difference between DBD group and DBCD group （P〉0.05））. The structures of bile duct were intact in both DBD and DBCD groups, while the biliary epithelium was totally damaged in DCD group. Under electron microscope, the DBD hepatocytes were characterized by intact cell membrane, well-organized endoplasmic reticulum, mild mitochondria edema and abundant glycogens. Broken cell membrane, mild inflammatory cell infiltration and sinusoidal epithelium edema, as well as reduced glycogen volume, were found in the DBCD hepatocytes. The DCD hepatocytes had more profound cell organelle injury and much less glycogen storage. In conclusion, the preservation injury of DBCD liver allografts is much less severe than that of un-controlled DCD, but more severe than that of DBD liver allografts under electron microscope, which might reflect post-transplant liver function to some extent.

Effect of cholic acid on fetal cardiac myocytes in intrahepatic choliestasis of pregnancy

This study examined the effect of cholic acid （CA） on cultured cardiac myoeytes （CMs） from neonatal rats with an attempt to explore the possible mechanism of sudden fetal death in intra- hepatic cholestasis of pregnancy （ICP）. Inverted microscopy was performed to detect the impact of CA on the beating rates of rat CMs. MTT method was used to study the effect of CA on the viability of CMs. CMs cultured in vitro were incubated with 10 ~maol/L Ca2＋-sensitive fluorescence indicator fluo-3/AM. The fluorescence signals of free calcium induced by CA were measured under a laser scanning confocal microscope. The results showed that CA decreased the beating rates of the CMs in a dose-dependent manner. CA could suppress the activities of CMs in a time- and dose-dependent manner. CA increased the concentration of intracellular free calcium in a dose-dependent manner. Our study suggested that CA could inhibit the activity of CMs by causing calcium overload, thereby leading to the sudden fetal death in ICP.     

Effects of tacrolimus and cyclosporine treatment on metabolic syndrome and cardiovascular risk factors after renal transplantation: a meta-analysis

Background The therapeutic success of renal transplantation has been largely attributable to the development of effective and balanced immunosuppressive treatment regimens.This study provides a meta-analysis of a series of randomized controlled trials that compared the effects of tacrolimus and cyclosporine on metabolic syndrome （MetS） and cardiovascular risk factors after renal transplantation.Methods We searched various electronic databases and bibliographies,including MEDLINE,the Cochrane Central Register of Controlled Trials,and EMBASE,for relevant studies published prior to October 2012.Results Our meta-analysis included five randomized controlled trials that examined a total of 923 patients.The tacrolimus group and the cyclosporine group exhibited no significant differences in MetS incidence after renal transplantation; risk ratio （RR）：1.06,95％ confidence interval （C/）：0.73-1.55,P=0.76.Cyclosporine treatment was associated with a higher incidence of hyperlipidemia （RR：0.50,95％ CI：0.39-0.64,P ＜0.01）.Although there were no statistically significant differences,cyclosporine treatment was associated with a higher incidence of hypertension （RR：0.91,95％ CI：0.83-1.00,P=0.06） after renal transplantation compared to tacrolimus treatment,and tacrolimus treatment was associated with a higher incidence of diabetes after renal transplantation （RR：1.79,95％ CI：0.98-3.27,P=0.06） compared to cyclosporine treatment.Conclusions Compared to tacrolimus treatment,cyclosporine treatment was associated with a higher incidence of hyperlipidemia.Future large-scale studies are expected to be conducted to further confirm our findings.

Neurological outcomes of patients admitted to the intensive care unit for cardiac arrest

Cardiac arrest （CA） is a major cause of death, with an estimated 300 000 cases of out-of-hospital CA reported in Europe and the United States each year. Advances in resuscitation techniques have improved survival such that approximately one-third of patients achieve return of spontaneous circulation （ROSC）. Nonetheless, only between half and one-third of patients who have achieved ROSC survive until discharge.     

May artificial sweeteners not sugar be the culprit of dramatic increase of inflammatory bowel disease in China?

As we know, inflammatory bowel disease （IBD） is ,typically used as a general term for ulcerative colitis （UC） and Crohn＇s disease （CD）, two highly related debilitating diseases of the digestive tract with similar clinical, pathological, and epidemiological features. Both UC and CD are most prevalent in young adults and still incurable. The patients usually depend on constant heavy medication and frequently need multiple devastating surgeries such as bowel resection, proctocolectomy, ileostomy, and ileal pouch-anal anastomosis.     

Association of renal function with cardiac reverse remodeling and long-term outcome in heart failure patients following cardiac resynchronization therapy

Background Renal insufficiency （RI） is significantly associated with clinical prognosis in patients with heart failure （HF）,but direct evidences on the relation between renal function and clinical outcome in patients receiving cardiac resynchronization therapy （CRT） are limited.The aim of the current study was to systematically evaluate the association of baseline and 6-month renal function with cardiac reverse remodeling and long-term outcome after CRT.Methods We retrospectively evaluated 190 consecutive patients who underwent CRT at Fuwai Hospital from January 2008 to April 2013.Renal function tests,echocardiographic measurement,and clinical parameters at baseline and after 6 months of CRT were performed.Primary endpoint events included all-cause mortality,cardiac transplantation,and unplanned hospitalizations for HF.Results At baseline,compared with normal renal function or mild RI （estimated glomerular filtration rate （eGFR） 〉-60 ml·min-1·1.73 m-2）,moderate-to-severe RI （eGFR 〈60 ml·min-1·1.73 m-2） exerted a negative influence on cardiac reverse remodeling parameters.At 6-month follow-up,114 （60.0%） patients were classified as responders and showed significant renal function improvement,whereas renal function deteriorated in non-responders and subsequently 41 （25.6%） patients developed worsening renal function （WRF）.During the mean follow-up of （24.3±17.1） months,both patients with baseline eGFR 〈60 ml·min^-1·1.73 m^-2 and those with WRF experienced worse event-free survival （P 〈0.01,respectively）.Conclusions：This analysis identified that baseline eGFR as well as WRF after CRT were found to be independent determinants of the combined endpoints of all-cause mortality and HF-related hospitalizations in CRT recipients.     

High prevalence of obstructive sleep apnea in Marfan’s syndrome

Objective To review the current evidence about the prevalence of obstructive sleep apnea in patients with Marfan＇s syndrome,and discuss some proposed potential mechanisms for this relationship.Data sources The data in this review were mainly from Medline and PubMed articles published in English from 1990 to 2013.The search term was ＂Marfan＇s syndrome and sleep apnea＂.Study selection Clinical evidence about the epidemiology of obstructive sleep apnea in patients with Marfan＇s syndrome; the mechanism that causes obstructive sleep apnea; interventional therapy for patients with Marfan＇s syndrome,and coexisting obstructive sleep apnea.Results A high prevalence of obstructive sleep apnea exists in patients with Marfan＇s syndrome.The potential reasons are craniofacial abnormalities and lax upper airway muscles,which lead to high nasal airway resistance and upper airway collapse.Obstructive sleep apnea mechanically deteriorates aortic dilatation and accelerates progression of aortic aneurysms.The condition is reversible and rapid maxillary expansion and adequate continuous positive airway pressure therapy are possible effective therapies to delay the expansion of aortic diameter in patients with Marfan＇s syndrome.Conclusions Obstructive sleep apnea is strongly associated with Marfan＇s syndrome.Craniofacial abnormalities and lax upper airway are the main mechanisms.Untreated obstructive sleep apnea accelerates progression of aortic dissection and rupture.Effective therapies for obstructive sleep apnea could postpone the aortic dilatation in patients with Marfan＇s syndrome.     

Presence of notched QRS on paced electrocardiographs as a predictor of poor response to cardiac resynchronization therapy

Background Cardiac resynchronization therapy （CRT） on patients with advanced and refractory heart failure has made remarkable progress.Clinically,notched QRS （nQRS） is commonly seen on electrocardiographs （ECGs） with bundle branch block morphology and on paced ECGs after implantation of a CRT device,which may reflect the heterogeneity of ventricular myocardial depolarization and electrical activity.The aim of this study was to determine whether patients with more nQRS myocardial segments on paced ECGs had a worse response to CRT than patients with fewer nQRS myocardial segments.Methods We prospectively enrolled 56 patients of CRT with chronic heart failure from People＇s Hospital affiliated to Peking University from January 2007 to October 2013.Based on nQRS segments on ECGs before CRT,we allocated them to two groups：fewer nQRS （〈2） myocardial segments （lateral,inferior,anterior segments） group （F-nQRS,G1,n=23） and more nQRS （≥2） myocardial segments group （M-nQRS,G2,n=33）.Then according to nQRS segments on ECGs after CRT,we divided them into two groups similarly：fewer nQRS （〈2） myocardial segments group （G3,n=24） and more nQRS （≥2） myocardial segments group （G4,n=32）.This study was approved by the ethics committee of People＇s Hospital.Results At 6 months in the baseline-ECG group,there was a greater absolute increase in left ventricular ejection fraction （LVEF） in G2 than in G1 （（11.5±8.9）% vs.（5.5±10.4）%,P=0.023）,with the incidence of nonresponse lower in G2than in G1 （9.1% vs.39.1%,P=0.018）.In the paced-ECG group,the absolute increase in LVEF was less in G4 than in G3 （（6.4±8.8）% vs.（12.5±10.4）%,P=0.024） and the incidence of nonresponse was higher in G4 than in G3 （31.3% vs.8.3%,P=0.039）.Multivariate analysis showed that fewer nQRS （〈2） myocardial segments on paced ECGs （odds ratio 13.920） was a predictor of positive response to CRT.Conclusion nQRS ≥2 myocardial segments （lateral,inferior,anterio
