Professor & Director Division of Geriatric Psychiatry 718-287-4806 What are the differences between older and younger persons with mental illness Clinically significant depression in community dwelling elderly: 8% to 16%, with major depression being about 2%. The 1-year incidence of clinically significant depression is highest in those age 85+-13% Depressive mood disorders decrease with age but depressive symptoms are more frequent among the old-old(age 75+) but may be due to factors associated with aging such as higher proportion of women, more physical disability, more cognitive impairment, and lower income. Prevalence of depression among older persons in various settings: Medically and surgically hospitalized persons-major depression 1012% and an additional 23% experiencing significant depressive symptoms. Primary Care Physicians: 5-10% have major depression and another 15% have minor or subsyndromal depression. Approximately one-fourth of medically ill persons suffer from clinical depression! Results:maintenance Rx with combination of meds & psychotherapy>meds alone >placebo. Persons aged 70+ (mostly first episodes) who have responded to antidepressants, did better if maintained on medication(65% no recurrence) vs placebo(32% no recurrence) over 2 yrs. Rationale: Among primary care patients with depression, only a small fraction receives adequate treatment in primary care or sees a mental health specialist. Although treatment of depression in primary care has improved, few improvements deal with the specific needs of elderly patients. Treatment options included pharmacotherapy, and two behavioral therapy approaches. Consulting psychiatrists saw about 10% of patients, typically treatment non-responders. Folate Suicide: Increases with Age White male Black female Suicide the frequency is highest for older white males at 62/100,000. Thus, roughly between 10-20% of widows develop clinically significantly depression in the first year of bereavement.

For example pomegranate juice impotence priligy 90mg on-line, all angiosarcomas are considered high grade and should be treated as such impotence in men over 60 effective priligy 90mg. In contrast erectile dysfunction joke purchase 30mg priligy with mastercard, many chondrosarcomas are associated with slow growth and low rates of metastasis erectile dysfunction thyroid generic priligy 30 mg with visa. Histological subtyping therefore remains critical in predicting the biological behaviour of tumours. The malignant grade should also be provided in all sarcoma cases for the purpose of prognostication. Again, grading should be performed prior to treatment as neoadjuvant medical therapies may affect these findings and limit the usefulness of grading of a subsequent resection specimen. Chondroblastic and fibroblastic tumours are usually of lower grade (grade 1 or 2). An absence of cartilaginous lobulation and the presence of spindle cell forms are characteristics of high-grade (grade 3) lesions and are associated with poorer prognosis. Five-year overall survival is better in low-grade tumour and poor outcome is associated with positive surgical Table 1: Federation Nationale des Centres de Lutte Contre le Cancer histological grading criteria Tumour differentiation 1: Well 2: Moderate 3: Poor Necrosis (macro and micro) 0: Absent 1: <50% 2: >50% Mitotic count (n/10 high-power fields) 1: n<10 2: 10-19 3: n20 Abstract Head and neck sarcomas are a rare diverse group of neoplasms arising within soft tissues or bones. Multimodality treatment plans including surgery, radiation and chemotherapy are often indicated. This article provides an overview of the presentation, pathology and management of these lesions. Due to the relative rarity of the condition, published data on management and outcomes of head and neck sarcomas are limited, based on small series of patients. Most of these studies report retrospective cohorts managed over a number of decades to obtain a sufficient numbers. Evolution of imaging, surgical technique and adjuvant therapies make conclusions from such small series difficult to interpret. In contrast to sarcomas elsewhere, wide surgical margins are more difficult to achieve and the cosmetic and functional impact of major head and neck resections are significant. However, various familial syndromes, environmental carcinogens and oncogenic viruses along with previous exposure to ionizing radiation have been implicated. Radiation exposure is a recognised risk factor in the late development of secondary sarcoma. Overall, osteosarcoma is the most common radiation-induced sarcoma for all body sites. In the head and neck region, malignant fibrous Key words Sarcoma, head and neck cancer, staging, management Conflict of interest None Introduction Head and neck sarcomas are a rare heterogeneous group of cancers which can arise in the mesenchymal tissues (bones or within the soft and connective tissues). They account for approximately 2% to 15% of all sarcomas, and represent approximately 1% of head and neck malignancies1. The sum of the scores of the three criteria determines the grade of malignancy Grade 1: 2 and 3; Grade 2: 4 and 5; Grade 3: 6, 7 and 8. As for histological subtypes, angiosarcoma and rhabdomyosarcoma have poor overall survival whilst pleomorphic sarcoma, fibrosarcoma, leiomyosarcoma and liposarcoma have better prognosis20. Due to the rarity and heterogeneity of these lesions (over 30 recognised histological subtypes of variable grade), it has been difficult to establish a working system to accurately stage all forms of this heterogeneous disease. Resection with clear margins is the aim in order to maximise the chance of local control. The role of adjuvant therapy is less clear and will depend on tumour type and resection status. Although there is no consensus regarding margin width, a 2cm margin is considered acceptable4. This presents a challenge in head and neck due to the need to preserve critical structures, functional anatomy and in order to minimise cosmetic defects. Elective treatment of the neck is rarely indicated due to the low rates of nodal disease14. Adjuvant radiotherapy should be considered in cases with intermediate to high grade, lesions with >5cm, and for resections with close or positive margins 4. In addition, recurrence after surgical management alone will be considered for re-resection with post-operative radiotherapy.

The maladaptive changes in behavior represent attempts to minimize or avoid panic attacks or their conse quences erectile dysfunction pills from india purchase priligy 60mg on-line. Examples include avoiding physical exertion erectile dysfunction drugs and glaucoma discount priligy 60mg line, reorganizing daily life to ensure that help is available in the event of a panic attack erectile dysfunction doctor lexington ky priligy 30mg sale, restricting usual daily activities erectile dysfunction treatment delhi priligy 90 mg overnight delivery, and avoiding agoraphobia-type situations, such as leaving home, using public transportation, or shopping. Associated Features Supporting Diagnosis One type of unexpected panic attack is a nocturnal panic attack. In the United States, this type of panic attack has been estimated to occur at least one time in roughly one-quarter to one-third of individuals with panic disorder, of whom the majority also have daytime panic attacks. In addition to worry about panic attacks and their conse quences, many individuals with panic disorder report constant or intermittent feelings of anxiety that are more broadly related to health and mental health concerns. For example, individuals with panic disorder often anticipate a catastrophic outcome from a mild phys ical symptom or medication side effect. In addition, there may be pervasive concerns about abilities to complete daily tasks or withstand daily stressors, excessive use of drugs. Prevalence In the general population, the 12-month prevalence estimate for panic disorder across the United States and several European countries is about 2%-3% in adults and adolescents. In the United States, significantly lower rates of panic disorder are reported among Latinos, African Americans, Caribbean blacks, and Asian Americans, compared with non-Latino whites; American Indians, by contrast, have significantly higher rates. Lower estimates have been reported for Asian, African, and Latin American countries, ranging from 0. The gender differentiation occurs in adolescence and is already observable before age 14 years. Although panic attacks occur in children, the overall prevalence of panic disorder is low before age 14 years (<0. The rates of panic disorder show a gradual increase during ad olescence, particularly in females, and possibly following the onset of puberty, and peak dur ing adulthood. Development and Course the median age at onset for panic disorder in the United States is 20-24 years. A small number of cases begin in childhood, and onset after age 45 years is unusual but can occur. Some in dividuals may have episodic outbreaks with years of remission in between, and others may have continuous severe symptomatology. Only a minority of individuals have full remission without subsequent relapse within a few years. The course of panic disorder typically is complicated by a range of other disorders, in particular other anxiety disor ders, depressive disorders, and substance use disorders (see section "Comorbidity" for this disorder). Although panic disorder is very rare in childhood, first occurrence of "fearful spells" is often dated retrospectively back to childhood. As in adults, panic disorder in adolescents tends to have a chronic course and is frequently comorbid with other anxiety, depressive, and bipolar disorders. To date, no differences in the clinical presentation between adoles cents and adults have been found. However, adolescents may be less worried about addi tional panic attacks than are young adults. Lower prevalence of panic disorder in older adults appears to be attributable to age-related "dampening" of the autonomic nervous system response. Many older individuals with "panicky feelings" are observed to have a "hybrid" of limited-symptom panic attacks and generalized anxiety. Also, older adults tend to attribute their panic attacks to certain stressful situations, such as a medical pro cedure or social setting. Older individuals may retrospectively endorse explanations for the panic attack^which would preclude the diagnosis of panic disorder), even if an attack might actually have been unexpected in the moment (and thus qualify as the basis for a panic disorder diagnosis). This may result in under-endorsement of unexpected panic at tacks in older individuals. Thus, careful questioning of older adults is required to assess whether panic attacks were expected before entering the situation, so that unexpected panic attacks and the diagnosis of panic disorder are not overlooked. While the low rate of panic disorder in children could relate to difficulties in symptom reporting, this seems unlikely given that children are capable of reporting intense fear or panic in relation to separation and to phobic objects or phobic situations. Therefore, clinicians should be aware that unexpected panic attacks do occur in adolescents, much as they do in adults, and be attuned to this possibility when encountering adolescents presenting with episodes of intense fear or distress. Although separation anxiety in childhood, especially when severe, may precede the later development of panic disorder, it is not a consistent risk factor. Reports of childhood experiences of sexual and physical abuse are more common in panic disorder than in certain other anxiety disorders.

Teenagers experience this at high rates because the sebaceous glands become active during puberty do erectile dysfunction pills work discount priligy 30mg on-line. Hormones that are especially active during puberty stimulate the release of sebum erectile dysfunction doctor philadelphia cheap 30mg priligy fast delivery, leading in many cases to blockages intracavernosal injections erectile dysfunction purchase priligy 90 mg amex. The tissue is fibrous and does not allow for the regeneration of accessory structures impotence doctor purchase priligy 60 mg otc, such as hair follicles, and sweat or sebaceous glands.

The rigid, yet flexible skeleton acts as a framework to support the other organs of the body. The movable joints allow the skeleton to change shape and positions; that is, move. Parts of the skeleton enclose or partly enclose various organs of the body including our brain, ears, heart, and lungs. The mineral component of bone, in addition to providing hardness to bone, provides a mineral reservoir that can be tapped as needed. Additionally, the yellow marrow, which is found in the central cavity of long bones along with red marrow, serves as a storage site for fat. Functionally, the tarsal provides limited motion, while the metatarsal acts as a lever. Functionally, the femur acts as a lever, while the patella protects the patellar tendon from compressive forces. The open spaces of the trabeculated network of spongy bone allow spongy bone to support shifts in weight distribution, which is the function of spongy bone. Intramembranous ossification is complete by the end of the adolescent growth spurt, while endochondral ossification lasts into young adulthood. The flat bones of the face, most of the cranial bones, and a good deal of the clavicles (collarbones) are formed via intramembranous ossification, while bones at the base of the skull and the long bones form via endochondral ossification. Like the primary ossification center, secondary ossification centers are present during endochondral ossification, but they form later, and there are two of them, one in each epiphysis. Open reduction requires surgery to return the broken ends of the bone to their correct anatomical position. The external callus is produced by cells in the periosteum and consists of hyaline cartilage and bone. To do this, I would recommend ingesting milk and other dairy foods, green leafy vegetables, and intact canned sardines so she receives sufficient calcium. To alleviate this condition, astronauts now do resistive exercise designed to apply forces to the bones and thus help keep them healthy. Low vitamin D could lead to insufficient levels of calcium in the blood so the calcium is being released from the bones. The reduction of calcium from the bones can make them weak and subject to fracture. It is centrally located, where it forms portions of the rounded brain case and cranial base. When this occurs in thoracic vertebrae, the bodies may collapse producing kyphosis, an enhanced anterior curvature of the thoracic vertebral column. The bones of the limbs, ribs, and vertebrae develop when cartilage models of the bones ossify into bone. It consists of 80 bones that include the skull, vertebral column, and thoracic cage. The appendicular skeleton consists of 126 bones and includes all bones of the upper and lower limbs. It also gives bony protections for the brain, spinal cord, heart, and lungs; stores fat and minerals; and houses the blood-cell producing tissue. It is subdivided into the rounded top of the skull, called the calvaria, and the base of the skull. These are the paired parietal and temporal bones, plus the unpaired frontal, occipital, sphenoid, and ethmoid bones. The facial bones support the facial structures, and form the upper and lower jaws, nasal cavity, nasal septum, and orbit. These are the paired maxillary, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones, and the unpaired vomer and mandible bones.
