AbstractThe peripheral high-flow vascular malformation (HFVM) comprises arteriovenous malformation (AVM) and fistula (AVF), shows varied clinical presentation (ranging from subtle skin lesion to life-threatening congestive heart failure), and frequently poses diagnostic and therapeutic challenges. Importance of assigning a specific diagnosis to the vascular malformation cannot be overstated, as the treatment strategy is based on the type of vascular anomaly. Although the International Society for the Study of Vascular Anomalies (ISSVA) classification system is the most commonly accepted system for classifying congenital vascular anomalies in clinical practice, the Cho–Do et al classification is of utmost help in guiding optimal mode of treatment in peripheral AVM. Although transarterial approach remains the most commonly employed route for peripheral AVM embolization, the role of transvenous and direct percutaneous approach is ever increasing and the final decision on the approach depends on angioarchitecture of the AVM. In this article, we review various commonly employed classification systems for congenital vascular anomalies, and describe clinical features, imaging and treatment strategies for peripheral arteriovenous malformation (PAVM).

Abstract Arteriovenous malformations (AVMs) are congenital vascular anomalies resulting from defects in angiogenesis. Approximately 40% of AVMs go undetected after birth and only experience the delayed clinical onset of symptoms in adulthood. AVMs are rare, representing only 1.5% of all vascular anomalies. The most common sites for the aberrant vascular nidus are the oral cavity and maxillofacial region, which represent 50% of the cases. AVMs are the most challenging and life-threatening form of vascular malformation. Exsanguination, thrombus detachment and embolization are the most hazardous operative risks. Small case series revealed a 75% recurrence rate during a 5-year follow-up, which adds another layer of complexity to their management. Large lesions in the head and neck cause deformation to the patient and present a challenge to the surgeon during their excision among vital structures and reconstruction of the 3D complex defects.

We report the third presentation of an intermixed arteriovenous malformation and hemangioblastoma. The rare occurrence of the diagnostic histologic features of both a neoplasm and vascular malformation in a single lesion is more common in gliomas, as angioglioma, and is termed an 'intermixed’ lesion. We review the literature concerning the developmental biology of each lesion, and potential interplay in the formation of an intermixed vascular neoplasm and vascular malformation. The roles of cellular origin, genetic susceptibility, favourable microenvironment, altered local gene expression and key regulatory pathways are reviewed. Our review supports angiography and genetic profiling in intermixed lesions to inform management strategies. Consideration should be given to multimodality therapeutic interventions as required, including microsurgical resection, stereotactic radiosurgery and further research to exploit emerging molecular targets.

A transactional understanding of problem behaviours recognizes that parents, partners, and other loved ones can often be very relevant to the chain of a client’s self-harm, suicidal behaviour, aggression, and other targets. Because the role of family members is important but often neglected, this chapter focuses primarily on DBT family skills interventions relevant to patient life-threatening behaviours. However, these interventions can readily be adapted for other targets later in treatment. This chapter outlines circumstances under which DBT family interventions might be particularly useful, specific targets to be addressed, rules to establish a treatment target hierarchy, a general protocol for how to conduct a family session, and helpful family session management strategies. DBT family interventions provide an efficient way to augment individual outcomes in DBT and create a more validating family environment that is beneficial for both the client and his or her loved ones.

Vascular anomalies include a wide number of disorders from a simple birthmark to life threatening entities. One such vascular anomaly is venous varix which is a commonly encountered case by a general surgeon although venous varix occurring on the forehead as being reported here is a rarity. Authors present a case of swelling over forehead at orbital verge which becomes prominent on performing valsalva maneuver. Case is of a 10year old girl brought to OPD with complaints of swelling over the left side of forehead since birth which becomes prominent on valsalva maneuver, with no associated complaints of pain or difficulty in eye opening. On examination, there was a 2cm diameter swelling present over the left forehead just above the medial margin of left eyebrow. CECT Brain showed no bony or intra orbital extension. Patient underwent excision of the varix. Postoperatively patient recovered well and discharged with cosmetic satisfaction.

Av Malformation

ABSTRACT Arteriovenous (AV) malformation is a congenital vascular anomaly in which there is an abnormal connection between the arterial and venous system resulting from developmental arrest during embryogenesis. In children, they are rare and potentially life-threatening. In the present case, an 8-year-old male patient presented with a simple gingival swelling associated with mobility of the corresponding teeth, which appeared relatively simple to excise but had an AV malformation associated with it. Timely diagnosis and investigations revealed its presence and hence prevented a catastrophy from occurring. Conventional method of surgical ligation of the external carotid artery was done as an emergency procedure and surgical resection was done without compromising the associated anatomic structures. This procedure helped control the bleeding as well as achieved an uneventful healing. This case report intends to create an awareness among Pediatric Dentists regarding the condition and thereby preventing an uncontrolled and unmanageable hemorrhage occurring in the Dental Office.

Diagnostic Approaches

Angioedema is a disease characterized by various triggers and an increasing prevalence. The great Greek physician Hippocrates (377-460 BC), considered one of the most outstanding figures in the history of medicine and "Father of the Western Medicine," already used the term oídēma to describe „swelling of organs“. It took many centuries later until the first description of angioedema as a distinct medical entity was minted by Quinсke in 1882. The contemporary perception, defines аngioedema as a transient swelling of the skin or submucosal surface due to increased vascular permeability of small venules. The overlying skin may be normal or mildly erythematous. Over time, many causes and factors that cause or trigger angioedema have been discussed. There are two main types of angioedema without urticarial (histaminergic and nonhistaminergic) as the role of histamine in the pathogenesis of the disease is crucial. Angioedema is a frequent clinical condition that sometimes can be life-threatening. Different types of angioedema can be challenging to distinguish clinically. However, establishing a correct diagnosis is critical as different forms of angioedema require distinct treatment approaches. Implementation of contemporary differential diagnostic approaches could be a prerequisite for an accurate diagnosis, which secures appropriate management strategies are possible.

This article examines how the loss of perceived control over one's environment (i.e. “helplessness”) can result in anxiety, depression, or death in people who otherwise appear to have favorable prognoses. Particular reference is made to the role of helplessness as a potentially life threatening condition in the older patient. Four effects of helplessness are discussed along with their implications for treatment. The paper presents seven specific treatment strategies for combatting the condition of helplessness, all of which are compatible with the skills possessed by an occupational therapist.

The purpose of present study is to examine the role of learning strategies as moderator between meta-cognitive awareness and study habits among university students. Sample comprises of 200 students (100 male students and 100 female students) of various universities of Islamabad and Rawalpindi with age ranging from 18-25 years. In order to assess study variables questionnaires were used included Meta-Cognitive Awareness Inventory (Schraw & Dennison, 1994) measuring two-components of meta-cognition that are knowledge and regulation of cognition. Study habits demonstrated by the students were measured by the Study Habits Inventory (Wrenn, 1941). Motivated Strategies for Learning Questionnaire (Pintrich, Smith, Garcia, & McKeachie, 1991) which includes motivation and learning strategies scales. In the present study, only the learning strategies section was utilized, which measures the cognitive strategies and resource management strategies. Results revealed positive correlation between research instruments and are also having good reliability. Regression analysis reflected that meta-cognitive awareness predicts study habits among university students. Regression analysis also suggested that learning strategies including resource management strategies and cognitive strategies significantly moderates the relationship between meta-cognitive awareness and study habits. It is also explored gender differences on learning strategies, meta-cognitive awareness and study habits. Future implications of the study were also discussed.
