Medial Patellofemoral Ligament Reconstruction Reconstruction of the medial PF ligament is a very common procedure in our practice for the treat- ment of recurrent instability after failed patellar stabilization surgery. The medial patellofemoral ligament is the primary stabilizer against lateral dislocation or subluxation. Consequently if there is lateral patellar instability there is also an insuf- ficient medial patellofemoral ligament. It is com- mon to see persistent lateral instability of the patella after recovery from procedures that fail to address the insufficient ligament as the primary pathology. Procedures that intend to repair the failed medial structures may lead to an improve- ment in the symptoms during the first year post- surgery, but instability reappears after that period. We believe the reasons for the later failures are related to: (1) the material used to fix the medial ligament is inadequate, the failed retinacular tis- sue is extremely thin and friable leading to stretching over time, and (2) the medial structures are subject to greater than normal lateral displace- ment forces (skeletal malalignment, trochlear dys- Figure 21.

The morbidity and mortality of KD is associated with which of the following complications? Overwhelming sepsis caused by encapsulated organisms B order prinivil 2.5 mg overnight delivery. Coronary artery aneurysms and thrombosis Key Concept/Objective: To know the life-threatening complications of KD The morbidity and mortality (< 3%) of KD is overwhelmingly associated with the devel- opment of inflammatory coronary artery aneurysms cheap 10 mg prinivil otc, most of which are asymptomatic at the time of formation discount 2.5 mg prinivil. Thrombosis can 22 BOARD REVIEW occur in the aneurysms buy prinivil 2.5 mg, resulting in direct or embolic coronary artery occlusion prinivil 2.5 mg cheap. Coronary events may occur weeks or even many years after the febrile illness cheap prinivil 10mg line. A baseline echocar- diogram should be obtained at the time of the acute illness and should be repeated 2 and 6 weeks later. Early recognition of the disease and treatment with intravenous immunoglobulin and aspirin have significantly decreased the frequency of aneurysm for- mation and thrombotic coronary events. An 18-year-old woman comes to your clinic complaining of a rash on her legs. She reports having crampy abdominal pain and aching joints for several days. She also reports that the rash began yester- day evening and was worse this morning, and she complains that her skin is itchy. Her medical history is significant only for an upper respiratory infection 2 or 3 weeks ago that resolved spontaneously. Physical examination is notable only for trace edema and purpura, noted on both lower extremities. You perform a skin biopsy, which stains positively for IgA-containing immune complexes. This biopsy finding is most consistent with which of the following diseases? WG Key Concept/Objective: To know the clinical presentation and pathologic findings of Henoch- Schönlein purpura Cutaneous involvement can occur in many of the primary or secondary vasculitic syn- dromes. Large, medium-sized, or small vessel occlusion can cause livedo, Raynaud phe- nomenon, or necrosis. Purpura is the most common manifestation of small vessel vasculi- tis. Small vessel vasculitis, particularly when associated with infections, is frequently asso- ciated with immune complex deposition. Vasculitis primarily involving the postcapillary venules has been termed hypersensitivity vasculitis in older literature. Primary small ves- sel vasculitis may be limited to the skin or may be associated with visceral involvement, including alveolar hemorrhage; intestinal ischemia or hemorrhage; and glomerulonephri- tis. Purpura tends to occur in recurrent crops of lesions of similar age and is more pro- nounced in gravity-dependent areas. Biopsy is useful in excluding causes of nonvasculitic purpura such as amyloidosis, leukemia cutis, Kaposi sarcoma, T cell lymphomas, and cho- lesterol or myxomatous emboli. Tissue immunofluorescent staining is useful to support the diagnosis of Henoch-Schönlein purpura (specifically, IgA staining), systemic lupus erythe- matosus, or infection (the percentage of cases with positive results on immunofluorescent staining is not known). Patients with WG and CSS can present with purpura; however, they do not exhibit IgA deposits in the immunoflourescence stains. Urticarial vasculitis is a disease that affects the skin exclusively; very rarely, patients present with interstitial lung disease but not articular or abdominal complaints, as seen in this patient.

In any research prinivil 2.5mg amex, for example buy generic prinivil 5 mg online, into child protection neglect is a form of abuse in which a child is deprived of basic health and social needs cheap prinivil 10 mg online. If neglect is present as might be understood from Turney’s conception it relates to an absence or exclusion of care that parents should provide for their children order prinivil 5 mg without a prescription. In the case of a child 24 / BROTHERS AND SISTERS OF CHILDREN WITH DISABILITIES with disabilities the siblings may experience differential levels of care depending on the availability of the parents order prinivil 5mg overnight delivery, which may not equate with the needs of those siblings discount 10mg prinivil with mastercard, but equally may not be classified as neglect amounting to abuse. I define ‘neglect’ in this context as follows: Neglect is used to convey a form of social exclusion which may arise from a lack of understanding or awareness of need. This may be because individuals are ignorant of the needs of others. Here ‘neglect’ is used as a relative term concerning siblings who, compared with other members of the family, may receive differing levels of care and attention from their carers. In the latter case, neglect may be an omission caused by competing pressures rather than a deliberate act or intent. Social exclusion Exclusion is concerned with those on the margins of society, those who have an ‘inability to participate effectively in economic, social political and cultural life’ (Oppenheim 1998, p. Often exclusion is about the incapacity of individuals to control their lives, and it requires inclusive policies to bring about change, to provide an opportunity for each citizen ‘to develop their potential’ (Morris 2001, p. Indeed, as Middleton (1999) found, even the Social Exclusion Unit (http://www. It would seem that exclusion of children with disabilities is not a concept of which the Social Exclusion Unit has much understanding. This lack of recognition impacts on families with disabled children because participation with others in their daily lives is difficult in whatever form of relationship that takes, where an experience of potential exclusion may occur. Hence, the term ‘exclusion’ helps provide a benchmark when assessing the involvement of individuals within their daily activities. I define exclusion with regard to siblings as follows: Social exclusion is a deliberate prohibition or restriction which prevents a sibling from engaging in activities shared by others. It may be a form of oppression, as experienced when denying an individual his or her entitlement to express their views or a form of segregation when only individuals with certain characteristics are allowed to engage in THEORY AND PRACTICE / 25 particular activities (restrictive attitudes or membership entitlement based on race being examples). Empowerment The idea of empowerment is pertinent to the situation of siblings of children with disabilities and disabled people generally: it is based on the need for making choices (Sharkey 2000), a basic right of consumers. Empowerment may include power, as a worker may empower, by enabling access to a service that is needed (Dowson 1997, p. However, when children have disabilities, parents and indeed, professionals might, under- standably, tend to be more focused on the child with disabilities and not on the needs of siblings. The needs of sibling’s should also be recognised as part of the family experience of living with disability and siblings should be included in whatever concerns their brother or sister. Empowerment is defined as follows: Empowerment is about enabling choices to be made and is vital to the needs of individuals, especially so, if an element of choice is lacking, as it will be for some family members due to exclusion or neglect, deliberate or not. The initial stage of empowerment requires individuals to be included in decisions which concern their needs. This represents the first stage of enabling the process of choice and freedom of access to begin. The ‘key terms’, neglect, social exclusion and empowerment, were implicit in my pilot study (Burke and Montgomery 2001a), and now, following the research, I can clarify the sense behind this initial conceptual understand- ing. My prior concern was to promote the term ‘social inclusion’ rather than ‘social exclusion’ as defined above. This is because my research work revealed more ‘social exclusion’ than the polar opposite ‘inclusion’. Indeed, the process of empowerment itself should seek to redress the position of exclusion by promoting an inclusive experience. This under- standing enables us to begin to prescribe a role for welfare professionals, defining their task as enabling families to become included families – that is, helping family members to make choices from a range of support services.

Successful components of interventions used in clinical trials include review and alterations in medications order prinivil 2.5 mg free shipping, bal- ance and gait training generic 5mg prinivil amex, muscle-strengthening exercises buy generic prinivil 5 mg line, improvement of postural hypo- tension buy prinivil 5 mg visa, home-hazard modifications discount 5 mg prinivil fast delivery, and specific medical and cardiovascular treatments generic 2.5mg prinivil visa. Tai Chi exercises to enhance balance and body awareness, when combined with bal- ance training, may also reduce the rate of falls. A randomized trial of Tai Chi exercise for 15 weeks in 200 persons 70 years of age and older resulted in a 47% decrease in falls after a 4-month follow-up period. A 77-year-old man presented to your clinic for evaluation 2 weeks ago and was noted to be hypertensive (this was the second time his blood pressure was determined to be elevated). The patient was started on a diuretic and an ACE inhibitor for his hypertension. He was also started on a regimen of daily low-dose aspirin. Today the patient is brought in by family members for evaluation of confusion. They state that his change in mental status is new and began after he started taking his new medications. Which of the following statements regarding iatrogenic illness in the geriatric population is false? The most common documented cause of iatrogenic illness is adverse drug reactions, usually associated with polypharmacy B. Because most drugs are eliminated via the hepatic system, lower maintenance doses of medications are needed to avoid iatrogenic side effects of prescribed medications C. Ways to prevent nosocomial infections include hand washing, ele- vating the patient’s head to prevent aspiration, and using narrow- spectrum antibiotic agents when indicated D. Drug distribution is altered by aging, primarily because of body- composition changes, with a decrease in total body water and lean body mass and a relative increase in body fat 8 INTERDISCIPLINARY MEDICINE 21 Key Concept/Objective: To understand the most common causes of iatrogenic illnesses in geri- atric patients and how to prevent them Iatrogenic, or physician-induced, illness results from a diagnostic procedure or thera- peutic intervention that is not a natural consequence of the patient’s disease. Iatrogenic illnesses include complications of drug therapy and of diagnostic or therapeutic proce- dures, nosocomial infections, fluid and electrolyte disorders, and trauma. The most common documented cause of iatrogenic illness is adverse drug reactions, usually asso- ciated with polypharmacy. Adverse drug events are more likely to occur in elderly patients because of the age-related changes in drug metabolism, the occurrence of mul- tiple comorbidities, and the use of polypharmacy. The incidence of adverse drug reac- tions increases with advancing age and the number of chronic diseases requiring drug therapy. The concomitant use of several medications increases the risk of drug interac- tions, unwanted effects, and adverse reactions. Many medications should be used with special caution in elderly patients because of age-related changes in drug pharmacoki- netics (drug disposition) and pharmacodynamics (target tissue effects). Although drug absorption is not reduced in healthy elderly persons, absorption of medications can be reduced by disease states (e. Drug distribution is altered by aging, primarily because of body-composition changes, with a decrease in total body water and lean body mass and a relative increase in body fat. Consequently, water-sol- uble drugs achieve a higher serum concentration, whereas lipid-soluble drugs have a prolonged elimination half-life. Drug elimination is mainly influenced by renal func- tion. The age-associated decrease in renal function, which results in decreased creati- nine clearance, necessitates lower maintenance doses of renally excreted drugs in eld- erly patients. The prevention of iatrogenic illness resulting from the inappropriate pre- scribing of drugs begins with an understanding of the rational use of medications in elderly patients. In general, prescribing the fewest medications at the lowest needed dosages is a rational approach to the prevention of iatrogenic illness.
