BACKGROUND In the presence of elevated cardiac filling pressures, the decline of blood pressure (BP) during the straining phase of a Valsalva manoeuvre is blunted or absent. We compared the use of non-invasively measured BP response to a Valsalva manoeuvre with clinical assessment and bioimpedance measurements to identify haemodialysis patients at risk of acute congestive heart failure (CHF). ...
Etoposide and ifosfamide are chemotherapeutic agents used frequently in the treatment of sarcomas and hematologic malignancies. Ocular side effects are rarely reported. We describe a case of a patient on etoposide and ifosfamide who presented with unilateral vision loss, anemia, and thrombocytopenia. The patient was found to have a large subinternal limiting membrane hemorrhage in the right eye...
A 23‐year‐old male presented with a history of sudden onset painless diminution of vision in the left eye (LE) following bouts of vomiting 4 months ago. His vision had gradually improved over the previous 2 months. There was no history of steroid use. Visual acuity was 20/20 in both eyes. There was no intraocular inflammation. An oblique oval lesion measuring 5 × 4 disc diameters was observed a...
A 52-year-old woman with hypertension presented with a sudden, painless and profound loss of vision in the left eye while doing farm work. Visual acuity was 0.08 only in the affected eye. Ophthalmoscopic examination revealed a large dome-shaped subinternal limiting membrane (sub-ILM) haemorrhage and a subhyaloid haemorrhage located anterior to the sub-ILM haemorrhage. The latter also showed a n...
Introduction: Diabetic retinopathy is one of the most important complications of type 1 and 2 diabetes, which is the most important cause of blindness in people aged 20 to 74. This study aimed to determine the prevalence of retinopathy in newly diagnosed type 2 diabetes mellitus at the Diabetes Center of 5th Azar Hospital in Gorgan. Materials and Methods: A total of 260 patients with newly diag...
Aneurysm of the sinus of Valsalva is a rare cardiac abnormality. Unruptured sinus of Valsalva aneurysm is usually asymptomatic, however, a ruptured aneurysm typically leads to an aortocardiac shunt and progressively worsening heart failure. We report a case of a 17-year-old male who suffered an aneurysm of the sinus of Valsalva rupture into the right atrium who manifested sudden dyspnea and acu...
Introduction & Objective: Diabetes mellitus is one of the most common chronic diseases in western developed countries and developing countries, whose prevalence is increasing worldwide. One of the vascular complications of diabetes is diabetic retinopathy. Given the prevalence of diabetic retinopathy and its complications in patients with type 2 diabetes, the aim of this study was to investigat...
A 70-year old man with a 15-year-history of chronic daily Valsalva maneuvers for left ear congestion presented with worsening vertigo and calvarial (occipitoparietal) and upper cervical hyperpneumatization. With continued frequent Valsalva maneuvers, subsequent studies demonstrated increased pneumatization with extension of air into the epidural space, causing mass effect on the left parietal l...
BACKGROUND The Valsalva manoeuvre is an internationally recommended treatment for supraventricular tachycardia, but cardioversion is rare in practice (5-20%), necessitating the use of other treatments including adenosine, which patients often find unpleasant. We assessed whether a postural modification to the Valsalva manoeuvre could improve its effectiveness. METHODS We did a randomised cont...
