Idiopathic pulmonary hemosiderosis (IPH) is a rare, life-threatening disease of uncertain etiology, characterized by recurrent intra-alveolar hemorrhages and usually afflicting young adults or children(l). Symptoms of lung hemorrhage are often few and atypical(2). Consequently, the condition may go unrecognized for a few years or months, presenting as recurrent iron deficiency anemia with no ac...

Research on covictims, family members, and close friends who have lost loved ones to intimate partner homicide (IPH) is a neglected area of study. We conducted phenomenological interviews with covictims to gain insights into risk and lethality, examined affidavits from criminal case files, and reviewed news releases. The data uncovered acute risk factors prior to the homicide, identified change...

A [(18)F]-FDG PET study was performed in a 44 year old man with proximal kinesigenic choreoathetosis (PKC) secondary to idiopathic primary hypoparathyroidism (IPH) before and 1 year after calcium/calcitriol therapy. The [(18)F]-FDG PET performed before the start of the therapy disclosed a significant bilateral hypometabolism in the ventral striatum. One year later, with the patient still under ...

Mathematical modeling is an important tool for water quality studies, and the integration of water quality models with geographic information systems (GIS) is very useful for information extraction and for results interpretation. In this context, this work presents the development of a water quality model coupled with GIS (MapWindow GIS) for representing impacts of point-sourced pollutants rele...

BACKGROUND AND PURPOSE We sought to investigate the association between carotid intraplaque hemorrhage (IPH) and ipsilateral symptoms of cerebral ischemia. METHODS A search was performed for clinical observational studies comparing the incidence of IPH between symptomatic and asymptomatic patients. Odds ratios (ORs) for IPH as a factor in the pathogenesis of neurologic events were calculated ...

BACKGROUND AND PURPOSE Pathologic studies suggest that neovascularization and hemorrhage are important features of plaque vulnerability for disruption. Our aim was to determine the associations of these features in carotid plaques with previous cerebrovascular ischemic events by using high-resolution CE-MRI. MATERIALS AND METHODS Forty-seven patients (36 men; mean age 72.5 ± 10 years) underwe...

Reversible cerebral vasoconstriction syndrome (RCVS) refers to a number of disorders characterized by severe and sudden-onset ("thunderclap") headaches and angiographic features of reversible, segmental, multifocal vasoconstriction of cerebral arteries. Although RCVS generally resolves without significant sequelae, a rare and possibly underrecognized hemorrhagic presentation has a worse potenti...

In this paper we study a Geo/T-IPH/1 queue model, where T-IPH denotes the discrete time phase type distribution defined on a birth-and-death process with countably many states. The queue model can be described by a quasi-birth-anddeath (QBD) process with countably phases. Using the operator-geometric solution method, we first give the expression of the operator and the joint stationary distribu...

Infantile periocular hemangiomas (IPH) are common benign vascular tumors that present early in childhood. They typically show a rapid nonlinear growth pattern a few weeks after birth during a proliferative phase, then continue with an involution phase and may result in serious ocular or systemic complications. Theses tumors may present in a range of small isolated lesions to multiple, diffuse i...

Idiopathic pulmonary hemosiderosis (IPH), the main cause of pulmonary hemosiderosis in children, is characterized by intermittent alveolar bleeding and hemosiderin-laden macrophages in sputum and in gastric lavage. The treatment is based on corticosteroids and cytotoxic drugs, under special conditions. We describe the case of a 7-year-old girl with IPH who achieved partial clinical remission wi...
