Implantation of a stent in a stenotic conduit between the left ventricle and aorta in a patient undergone surgery for a double outlet right ventricle

Abstract

Reinterventions for surgery complications in adult patients with complex congenital heart disease are often difficult and have a high operative risk. If anatomically possible, a percutaneous approach is an alternative to surgery. We report the case of a 36 year-old patient who underwent surgery for a double outlet right ventricle with transposition of the great arteries and pulmonary stenosis. On the days following the surgery, the patient was hemodynamically unstable due to a stenosis of the intraventricular Dacron conduit between the left ventricle and the aorta. Because of the fragility of the patient, additional surgery was not possible and a percutaneous approach was preferred. A Cheatham Platinum stent mounted on a balloon-in-balloon catheter was implanted with success in the stenotic intraventricular Dacron conduit.

The progress of traditional Chinese medicine in the treatment of aplastic anemia

Abstract

Aplastic anemia (AA) is a common hematologic disease that is characterized by hematopoietic failure of the bone marrow and pancytopenia of the peripheral blood, which can be divided into severe and non-severe aplastic ane-mia, or acute and chronic aplastic anemia according to the severity of the disease and the progress of the clinical course. During the past years, the advantages of Traditional Chinese Medicine (TCM) on the treatment of AA have been well clarified and its theory system has been improved as well. This review is mainly on representing the pathogenesis, therapeutic principle and method, research progression, and advantages of TCM on AA.

Successful pharmacotherapy for multiple acute decompensation events in a cirrhotic patient with acute-on-chronic liver failure: A case report

Abstract

Acute-on-chronic liver failure (ACLF) is a potentially lethal syndrome, which is characterized by an acute deterioration of liver function in patients with chronic liver diseases. The present paper reported that an alcoholic cirrhotic patient with ACLF developed septic shock, hydrothorax, ascites, hepatic encephalopathy, acute kidney injury, and acute upper gastrointestinal bleeding at the same hospitalization and was successfully rescued by pharmacotherapy alone without any invasive intervention.

Waterpipe tobacco smoking: A mini-review

Abstract

The waterpipe tobacco smoking is an ancient form of smoking that is present in the society since centuries. The majority of consumers of this exotic activity are still unaware of the serious consequences that this type of smoking has on the health of the smoker. The paucity of data related to the prevalence and extent of this habit in the society is still not available. In this present short review, the authors try to highlight this serious health issue and suggest preventive measures.

Advances in Stroke Prevention

Abstract

There have been recent advances in stroke prevention in nutrition, blood pressure control, antiplatelet therapy, anticoagulation, identification of high-risk asymptomatic carotid stenosis, and percutaneous closure of patent foramen ovale. There is evidence that the Mediterranean diet significantly reduces the risk of stroke and that B vitamins lower homocysteine, thus preventing stroke. The benefit of B vitamins to lower homocysteine was masked by harm from cyanocobalamin among study participants with impaired renal function; we should be using methylcobalamin instead of cyanocobalamin. Blood pressure control can be markedly improved by individualized therapy based on phenotyping by plasma renin and aldosterone. Loss of function mutations of CYP2D19 impair activation of clopidogrel and limits its efficacy; ticagrelor can avoid this problem. New oral anticoagulants that are not significantly more likely than aspirin to cause severe bleeding, and prolonged monitoring for atrial fibrillation (AF), have revolutionized the prevention of cardioembolic stroke. Most patients (~90%) with asymptomatic carotid stenosis are better treated with intensive medical therapy; the few that could benefit from stenting or endarterectomy can be identified by a number of approaches, the best validated of which is transcranial Doppler (TCD) embolus detection. Percutaneous closure of patent foramen ovale has been shown to be efficacious but should only be implemented in selected patients; they can be identified by clinical clues to paradoxical embolism and by TCD estimation of shunt grade. “Treating arteries instead of treating risk factors,” and recent findings related to the intestinal microbiome and atherosclerosis point the way to promising advances in future.

Aplastic anemia in China

Abstract

Aplastic anemia (AA) is a hematologic disease characterized by pancytopenia. Up to now, severe aplastic anemia (SAA) has been recognized by international and domestic scholars as an autoimmune disease with bone marrow (BM) failure mediated by the hyperfunctional T lymphocytes. The incidence of AA is more in China compared with other countries. In the recent years, both the pathogenesis and treatment of AA have made a great progress in our country. Thus, the therapeutic effect of AA was much better than before. Here, we conclude the researches of AA in China.

Cardiogenic shock after nifedipine administration in a pregnant patient: A case report and review of the literature

Abstract

We present a case of a 21-year-old Caucasian woman at 27 weeks of pregnancy who was admitted to the obstetric department for pre-term labor. She received 10 mg of nifedipine 4 times in 1 h, according to the internal protocol. Shortly after, she brutally deteriorated with pulmonary edema and hypoxemia requiring transfer to the intensive care unit (ICU) for mechanical ventilation. She finally improved and was successfully extubated after undergoing a percutaneous valvuloplasty of the mitral valve. This case illustrates a severe cardiogenic shock after administration of nifedipine for premature labor in a context of unknown rheumatic mitral stenosis. Nifedipine induces a reflex tachycardia that reduces the diastolic period and thereby precipitates pulmonary edema in case of mitral stenosis. This case emphasizes the fact that this drug may be severely harmful and should never be used before a careful physical examination and echocardiography if valvular heart disease is suspected.

Citrate: How to get started and what, when, and how to monitor?

Abstract

In most of the case, regional citrate anticoagulation is using diluted citrate around 1% depending on the types used in clinical practice. Diluted citrate is much more safer when compared to highly concentrated citrate around 4% or even more. In clinical practice, trisodium citrate is used in high concentration (around 30%) as a bactericidal agent with anticoagulant properties for locking deep venous catheters used in hemodialysis (HD; close to 25–30% of citrate). In this review article, buffer and anticoagulant potential of citrate are discussed during renal replacement therapy in critically ill patients with particular focus on the practical approach at the bedside.

Hepatic encephalopathy in patients in Lviv (Ukraine)

Abstract

Background and Objectives

Hepatic encephalopathy (HE) research has long been impeded by the vague definition of this disabling complication of liver failure. This article provides an overview of the etiology and impact of HE on neuromuscular functions as well as its role in the development of infections and anemia.

Materials and Methods

This was a descriptive study conducted in 36 patients with HE. Close monitoring of these patients was done by checking on several parameters.

Results

The etiological distribution: alcohol (67%), hepatitis C virus (HCV; 17%), HCV and alcohol (8%), hepatitis B virus (HBV; 3%), HBV and alcohol (3%), HBV and HCV (6%), and cryptogenic (3%). The laboratory results indicated an elevation of De Ritis level in 69% of cases and in 92% of total bilirubin values. The Halstead-Reitan (H-R) test score with regards to gender indicated that more than half of the patients had a score of 2, while only few cases received the scores 3 and 4. The frequency of H-R score with regards to Child-Pugh score showed the significant preponderance of Child-Pugh score of 7–9 (B): 58.3% compared to others groups of results, and these results indicated patients’ poor prognosis.

Conclusion

Findings showed the preponderance of female patients towards developing HE and the poor survival rate of patients older than 65 years. Alcohol and hepatitis C were the main causes associated with the development of HE. The neurological assessment marked the preponderance of Child-Pugh grades B and C and also the prevalence in female patients with neuropsychological disabilities through the assessment of H-R test.
