Authors are Rai B Ghoshal S Sharma SC et al., from the Department of Radiotherapy, Post Grade Institute of Medical Education and Research, Chandigarh, India. Male breast cancer is a rare disease representing 1% of all breast cancers and less than 1% of all cancers in men.The aim of the study was to observe the clinical and pathological features, evaluate the prognostic factors and to co-relate the outcome in patients of male breast cancer. Modified radical mastectomy followed by external radiation therapy is the standard treatment for male breast cancer. Hormone therapy, as an adjuvant treatment, is the first line approach in a majority of patients and chemotherapy is reserved for patients with poor prognostic factors.

PubMed, the Internet portal of biomedical and life sciences literature, indexed an interesting article, entitled Evolution of antiglomerular basement membrane glomerulonephritis into membranous glomerulonephritis. ( Pediatr Nephrol. 2007 Nov 13; ). Authors are Hecht N Omoloja A, Witte D et al., from the Department of Pediatrics, Wright State University Boonshoft School of Medicine, Dayton, OH, USA. Antiglomerular basement membrane glomerulonephritis (anti-GBM GN) is a rare disease characterized by autoantibodies to the alpha 3 chain of type IV collagen in the GBM. It is also known as Goodpasture’s syndrome when associated with pulmonary hemorrhage due to autoantibodies to the alpha 3 chain of type IV collagen also present in pulmonary alveoli. Even more rare is the evolution of anti-GBM GN into membranous nephropathy (MN). We report the management of a 9-year-old Caucasian girl with anti-GBM GN that evolved into MN and briefly review the literature. To access the full abstract of the article, click here.
PubMed, the Internet portal of biomedical and life sciences literature, indexed an interesting article, entitled Progressive Multifocal Leukoencephalopathy (Curr Neurol Neurosci Rep. 2007 Nov;7(6):461-469). Authors are Berger JR. from the Department of Neurology, University of Kentucky College of Medicine, USA. Progressive multifocal leukoencephalopathy (PML) was a rare disease until the advent of the HIV/AIDS pandemic. Recent interest in the disorder has been spurred by its appearance in patients treated with the monoclonal antibodies natalizumab and rituximab. Unless the accompanying underlying immune deficit can be reversed, PML typically progresses to death fairly rapidly. Treatment directed against the JC virus has been unhelpful, but an increased understanding of disease pathogenesis may result in effective therapeutic strategies.

PubMed, the Internet portal of biomedical and life sciences literature, indexed an interesting article, entitled Pulmonary Hypertension: Evaluation and Management (Compr Ther. 2007 Sep;33(3):150-161.). Authors are heresi GA Dweik R, from the Department of Pulmonary, Allergy and Critical Care Medicine, Cleveland Clinic, USA.. Pulmonary hypertension (PH) is a hemodynamic state characterized by elevation in the mean pulmonary arterial pressure and pulmonary vascular resistance leading to right ventricular failure and premature death. IPAH, formerly known as primary pulmonary hypertension (PPH), is a rare disease most commonly seen in women of childbearing age. Presenting symptoms and signs are nonspecific and include dyspnea on exertion, fatigue, and a loud pulmonary component of the second heart sound.Several targeted treatment options have become available in recent years and include parenteral and inhaled prostanoids, oral endothelin receptor antagonists, and oral phosphodiesterase type-5 inhibitors.

PubMed, the Internet portal of biomedical and life sciences literature, indexed an interesting article, entitled Treatment of Cerebral Venous and Sinus Thrombosis (Front Neurol Neurosci. 2008;23:132-143.). Authors are Masuhr F Einhäupl K. et al., from the Department of Neurology, Charité – Universitätsmedizin Berlin, Berlin, Germany. Cerebral venous and sinus thrombosis (CVST) is a rather rare disease which accounts for less than 1% of all strokes. Current therapeutic measures which are used in clinical practice include the use of anticoagulants such as dose-adjusted intravenous heparin or body weight-adjusted subcutaneous low molecular weight heparin, the use of thrombolysis, and symptomatic therapy including control of seizures and elevated intracranial pressure.There are no controlled data about the risks and benefits of certain therapeutic measures to reduce an elevated intracranial pressure (with brain displacement) in patients with severe CVST. Antiedema treatment (including hyperventilation, osmotic diuretics, craniectomy) should be used as life-saving interventions. To access the full abstract of the article, click here.
PubMed, the Internet portal of biomedical and life sciences literature, indexed an interesting article, entitled Anaphylaxis in childhood and adolescence. (Hautarzt. 2007 Nov 14). Authors are Ott H Lehmann S Wurpts G et al., from the Klinik für Dermatologie und Allergologie, Universitätsklinikum der RWTH Aachen, Pauwelsstraße 30, 52074, Aachen, Deutschland. Anaphylaxis represents a severe, systemic and potentially fatal hypersensitivity reaction that severely impairs the life of affected children. Foods are the most frequent triggers in children; less frequent causes include drugs and insect venom. Particularly in case of idiopathic anaphylaxis, systemic mastocytosis should be ruled out as a potential differential diagnosis in this age group as well. First line emergency treatment consists of parenteral epinephrine in a weight-adjusted dosage, and after cardiovascular stabilization systemic antihistamines and corticosteroids as well as inhaled beta-mimetics can be administered.

PubMed, the Internet portal of biomedical and life sciences literature, indexed an interesting article, entitled Arrhythmogenic right ventricular cardiomyopathy/dysplasia (Orphanet Journal of Rare Diseases 2007, 2:45doi:10.1186/1750-1172-2-45). Authors are Gaetano Thiene Domenico Corrado and Cristina Basso. Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a heart muscle disease characterized by life-threatening ventricular arrhythmias. Its prevalence has been estimated to vary from 1:2,500 to 1:5,000. ARVC/D is a major cause of sudden death in the young and athletes.The pathology consists of a genetically determined dystrophy of the right ventricular myocardium with fibro-fatty replacement, that it leads to right ventricular aneurysms. The clinical picture may include: a subclinical phase without symptoms and with ventricular fibrillation being the first presentation; an electrical disorder with palpitations and syncope, due to tachyarrhythmias of right ventricular origin; right ventricular or biventricular failure, requiring transplantation.

PubMed, the Internet portal of biomedical and life sciences literature, indexed an interesting article, entitled Thrombotic thrombocytopenic purpura and bone marrow necrosis as the initial presentation of lung cancer (Clin Appl Thromb Hemost. 2007 Oct;13(4):449-52). Authors are Sevinc A Kalender ME Pehlivan Y et al., from the Department of Medical Oncology, Gaziantep University, School of Medicine, Gaziantep Oncology Hospital, Gaziantep, Turkey. Thrombotic thrombocytopenic purpura (TTP) is a disseminated form of thrombotic microangiopathy. Although most cases are held to be idiopathic, its association with malignancy is well recognized, and it usually occurs at the terminal stage of cancer. Bone marrow necrosis (BMN) is another rare disorder defined pathologically as the necrosis of myeloid tissue and medullary stroma with preservation of bone. Although hematologic malignancy is the most common underlying disease associated with BMN, it can also be caused by solid tumors. The occurrence of TTP with BMN associated with lung cancer has not been reported in the English literature. To access the full abstract of the article, click here.
PubMed, the Internet portal of biomedical and life sciences literature, indexed an interesting article, entitled Laparoscopic Internal Marsupializaton for Large Nonparasitic Splenic Cysts: Effective Organ-Preserving Technique. (World J Surg. 2007 Nov 9). Authors are Palanivelu C Rangarajan M Madankumar MV et al., from the Division of Surgical Gastroenterology, Department of Surgery, GEM Hospital, India. Primary splenic cyst is a rare disease, and therefore there is no information regarding its optimal management. Most such cysts are classified as epithelial cysts. During the last few years, the laparoscopic approach has gained increasing acceptance in splenic surgery. We present our experience with the laparoscopic (organ-preserving) management of splenic cysts. Laparoscopic partial cystectomy/marsupialization is an acceptable procedure for the treatment of splenic cysts; and after short to mid-term follow-up, it seems that a reasonable rate of success is possible.
