A Clinician’s Guide to Integrative Oncology
n this book, we willرایگان!
n this book, we will use the term ‘Integrative Medicine practitioner’ to denote a practitioner who is qualified in western medicine and at least one other form of complementary medicine (typically this is often nutritional medicine, acupuncture, an/or mind–body medicine). We will use the term complementary medicine’ to denote those systems of medicine and therapies that lie utside of conventional (western) medicine, which onetheless can be complementary to orthodox medical care. It is of course recognised that in defining it as such, we are taking a somewhat Western-centric approach and that in some countries, forms of ‘complementary medicine’ such as Chinese medicine would not be considered ‘complementary’. The term ‘complementary medicine practitioner’ will be used to denote a healthcare practitioner, whose primary qualification is in a form of complementary medicine and who is not qualified in Western medicine.
A double-blind controlled study of a nonhydroquinone bleaching cream in the treatment of melasma
Background Melasma iرایگان!
Background Melasma is an acquired hypermelanosis predominantly affecting the face of women. It is often recalcitrant to treatment with hypopigmenting agents. Objective To assess the efficacy of a nonhydroquinone cream (Amelan M®) vs. another (Mela-D®) as treatment for melasma. Methods Twenty-two French women with bilateral epidermal and/or mixed melasma were enrolled in a split-faced prospective trial lasting 4 months during summer season weeks. Twelve patients applied once-daily Amelan M® to one side of the face with sun-protective factor 60 UVA sunscreen each morning and Mela-D® once-daily to the other side of the face. Pigmentation was measured objectively using a mexameter and the melasma area and severity index (MASI) were measured subjectively. Results The mean decrease of pigmentation was statistically significant on the MASI with both cream and only with Amelan M with the mexameter. Some adverse side effects were observed. Conclusions Amelan M® is really more effective than Mela D® cream on melasma. Even though some side effects were observed patients preferred the Amelan M-treated side.
A New Approach to Stone-reliefs of Persepolis
In the north easternرایگان!
In the north eastern part of the Persian Gulf in Iran, there is a region called Fars today and Parse in the past. In this mountainous region there is a mountain previously called Mehr (love) and now called Rahmat (Mercy) with a 2500 years old ruined palace still dazzling on its skirts, remaining from the Achaemenid reign over Iran from c.550 to 330BC. Despite considerable research on the religion of this dynasty, Iranologists have not still conclusively reached a definite opinion on this matter and if they have, it is based on questionable evidences and interpretations. Based on remaining inscriptions and stone-carvings of this monument, the article is an attempt to show that the kings of this dynasty were definitely followers of Zoroaster, who founded the first official religion of the world 6 to 7 centuries AD, with all the symbols found in this unique palace having Iranian roots which so far have wrongly been attributed to the beliefs of other peoples and civilizations.
A practical, algorithmic approach to diagnosing hair shaft disorders
The hair shaft is aرایگان!
The hair shaft is a unique structure composed of an inner cortex and a protective outer cuticle. Any defects in this normal structure due to genetics or the environment can lead to variations in physical properties. Thus one should suspect a hair shaft disorder if a patient presents with an abnormality or change in hair texture, appearance, manageability or ability to grow hair long. A key feature of the clinical evaluation is to determine whether there is hair breakage (increased fragility) by looking for broken hairs and performing a tug test. Once this determination is made, an algorithmic approach can be used to narrow the differential diagnosis: hair shaft disorders with and without fragility. A hair mount along with other directed questions and examination will almost always allow the clinician to make an in-office diagnosis. Common case scenarios, photographs, and practical tips are provided to illustrate the use of this algorithmic approach in the diagnosis of hair shaft disorders. We have also included a summary of the molecular defects where known, which can be helpful in providing a correlation with clinical findings, in counseling patients, and potentially offering treatment options.
A Relational Approach to Conceptualization, Assessment, and Treatment
This book outlines oرایگان!
This book outlines our unique conceptualization of perfectionism, as well as assessment and treatment approaches for it. It represents the culmination of over two decades of research and clinical work on this topic. Our primary purpose for writing this book is to offer insight into the complex construct of perfectionism—not only as a personality style involving traits and relational elements, but also as a clinically relevant personality vulnerability factor that predisposes individuals to myriad problems. We also provide information on appropriate assessment and treatment of those people who are paying a signifcant personal price for their perfectionism.

Abnormalities in the Adrenergic Control and the Rate of Lipolysis in Isolated Human Subcutaneous Adipose Tissue in Diabetes Mellitus
Subcutaneous adipose tissue was obtained from 9 patients with untreated diabetes mellitus and from 13 obese nondiabetics. After incubation with isoprenaline or noradrenaline, glycerol release and tissue cyclic AMP (cAMP) were determined. Basal glycerol release was twice as rapid from the diabetic adipose tissue. With isoprenaline, the cAMP concentration and the glycerol production was significantly higher in the diabetic adipose tissue. Noradrenaline did not increase glycerol production or cAMP concentration in the diabetic adipose tissue. Subcutaneous adipose tissue was also removed from the diabetics after antidiabetic treatment. Basal lipolysis was significantly reduced and noradrenaline significantly increased both glycerol release and cAMP production. With isoprenaline, cAMP production and glycerol release were significantly less after antidiabetic treatment than in the untreated state. The data provide evidence for increased a- as well as fl-adrenergic receptor sensitivity in human subcutaneous adipose tissue of untreated diabetic patients.

Academic Promotion for Clinicians
Medical schools in tرایگان!
Medical schools in the United States have approximately 166,000 faculty members (Fig. 1.1). The vast majority, about 121,000 (73%) individuals, are physicians, but faculty appointments are also held by many other health professionals .These clinicians have chosen academic practice despite the many career opportunities available in health care. In addition to the individual faculty member, many others including patients, learners, colleagues, institutions, and society have investments in clinicians enjoying long and productive careers in academic medicine. Unfortunately, the evidence points to widespread and deepening dissatisfaction with academic careers. While escalating demands for patient care and educational services are major factors in faculty dissatisfaction, the systems for academic promotion are part of the problem.

A 70-year-old womanرایگان!
A 70-year-old woman presents to the emergency department complaining of right lower quadrant pain for 4 days. Her examination shows a palpable mass in the right lower quadrant. A CT scan shows a large distended appendix measuring 4 cm in diameter, without periappendiceal fat stranding (Fig. 1.1). The diagnosis of appendiceal mucocele is made. An open appendectomy is performed without spillage of any contents. Pathology revealed mucosal hyperplasia without signs of atypia. The patient was scheduled for routine post-appendectomy follow up.
Alcohol and Aging
Population ageing isرایگان!
Population ageing is taking place in nearly all the countries of the world and this is expected to continue over the coming years . Alcohol problems often occur in later life and are associated with notable social, psychological, physical and economic consequences; however, in later life alcohol problems are often less obvious, misdiagnosed or go under-detected and under-reported . Alcohol consumption and alcohol-related deaths or problems have recently increased among older age groups in many developed countries, including the USA, Australia and several countries of the European Union . This increase in consumption, in combination with the ageing of populations worldwide, means that the absolute number of older people with alcohol problems is on the increase and a real danger exists that a “silent epidemic” may be evolving . Although there is growing recognition of this public health problem ,clinicians consistently under-detect alcohol problems and under-deliver behaviour change interventions to older people while nurses report that they do not engage with older people as they worry about depriving them of the social benefts of drinking . In order for health professionals to successfully intervene with older people who are experiencing alcohol problems, it is important to understand the underlying factors that may increase exposure to, or consumption of, alcohol. An understanding of the different trajectories among older drinkers may also help health professional in directing treatment towards those affected more severely .
Alzheimer’s disease: synaptic dysfunction and Aβ
Synapse loss is an eرایگان!
Synapse loss is an early and invariant feature of Alzheimer’s disease (AD) and there is a strong correlation between the extent of synapse loss and the severity of dementia. Accordingly, it has been proposed that synapse loss underlies the memory impairment evident in the early phase of AD and that since plasticity is important for neuronal viability, persistent disruption of plasticity may account for the frank cell loss typical of later phases of the disease. Extensive multi-disciplinary research has implicated the amyloid β-protein (Aβ) in the aetiology of AD and here we review the evidence that non-fibrillar soluble forms of Aβ are mediators of synaptic compromise. We also discuss the possible mechanisms of Aβ synaptotoxicity and potential targets for therapeutic intervention.
