He further highlighted the prevalence of the metabolic alteration over the venous–lymphatic impairment order 50 mg minocin with visa. Finally in 1976 discount minocin 50mg online, Reinharez generic minocin 50mg with amex, who had a deep knowledge of the lymphatic system buy minocin 50 mg line, described this disease as an endocrine-metabolic pathology having secondary vascular and lymphatic manifestations (2). In 1978, Binazzi, and later Curri—perhaps the greatest specialist on microcirculation together with Merlen—histologically proved the existence of microvascular alterations, dividing them into three groups: edema, ﬁbrosis, and sclerosis (hence the acronym EFP corresponding to edematous ﬁbrosclerotic panniculopathy). In his excellent book, published in Italy in 1978 and entitled Le microangiopatie, Curri says: ‘‘From a long time ago, nobody has questioned the fundamental axiom that capillaries play the most important role in the circulatory system, including the heart. This axiom is currently under review and latest ﬁndings are perplexing. Curri suspected there was something else beyond the capillary itself though he was unable to prove his assumption (3–7). Recent discoveries have led to different evaluations and, in 1997, we described in Le celluliti and in Flebologia Oggi our own conception of the cellulite disease as a ‘‘predo- minantly interstitial endocrine-metabolic pathology’’ (8–14). Cellulite is a ‘‘predominantly interstitial endocrine–metabolic pathophysiology. Alterations in the ﬁgure: Such alterations do not always involve a pathological con- dition, but they do determine a lack of harmony in the ﬁgure. They may also be asso- ciated with hereditary diseases or with a peculiar bone structure of the pelvis and rachis. Nearly always, however, they are associated with postural or foot alterations that should be studied dynamically for the diagnosis. Although they often elicit changes in the ﬁgure and cause the true cellulite disease, deﬁnite assistance for such alterations is not always possible because they sometimes require physical therapy and a change in lifestyle. Systemic and localized adiposity: The general contour of the human body derives its characteristics from the particular arrangement of the adipose panniculum upon the structure of bones and muscles. The human body is characterized by the presence of rigid fasciae, particularly, the deep muscular fascia that, starting from the skull base, extends continuously to the ankle and the metatarsus supporting many vascular, neuro-physiological, and orthopedic functions. In certain areas, the fascia is divided 46 & BACCI AND LEIBASCHOFF into two layers of hormone-dependent adipose tissue (steatomery), especially associated with procreation and containing insulin, estrogen, and calcium receptors. Such steato- meric adiposities, in their turn, provide roundness to the ﬁgure. It is also well known that such localized adiposities may only be eliminated through surgical therapy or liposculpture. Alterations in the ﬁgure are mainly determined by disorders in adipose areas, either steatomeric in nature (hereditary and sensitive to endocrine-metabolic signals) or subcu- taneous (sensitive to unbalanced diets, toxic substances, bacteria, and heavy metals). Excessive localized adiposity may involve numerous normal-sized cells (hyperpla- sia), a normal amount of big-sized cells (hypertrophy), or a combination of both. Localized areas of adiposity are frequently found in the lower part of a woman’s body, in the glutei, the abdomen, the ﬂanks, the upper external side of the hip, and the knee. The volume of some adipose tissues is conditioned, to a certain extent, by hormonal activity and should therefore be considered as normal. However, when such adipose char- acteristics do not agree with current aesthetic canons in fashion or when they elicit symp- toms, surgical intervention may be considered legitimate. Localized adiposity should be distinguished, nevertheless, from cellulite itself, even if an association of these two pathol- ogies is frequent. EFP: It is the traditional evolutionary degenerative disease of subcutaneous tissues that develops on a constitutional substrate closely linked with a series of predisposing and triggering factors. Localized areas of cellulite are frequently found in the lower part of a woman’s body, in the glutei, the abdomen, the ﬂanks, the upper external side of the hip, and the knee. PATHOPHYSIOLOGY OF CELLULITE & 47 According to the authors who described its histomorphology, it involves a sequence of events characterized by interstitial edema, connective ﬁbrous reaction, and the resulting sclerotic evolution. Each of these histopathological stages is associated with a different vascular stage (15,16). Thus T0 indicates normal vascularization, T1 the initial appearance of hypoxic areas, T2 the presence of hypoxic and hypometabolic areas, and T3 and T4 indicate the cold nodular evolution characterized by a thermographic plate resembling the skin of a leopard (70). Clinical studies and recent observations have demonstrated that EFP effectively repre- sents some types of the cellulite disease though it does not cover all clinical manifestations.

With this idea in mind, we have collected 981 case-based questions and created Board Review from M edscape. The list of topics is comprehensive, providing physicians an extensive review library covering all of adult internal medicine, as well as such subspecialties as psychiatry, neu- rology, dermatology, and others. The questions present cases of the kind commonly encountered in daily practice. The accompanying answers and explanations highlight key educational con- cepts and provide a full discussion of both the correct and incorrect answers. The cases have been reviewed by experts in clinical practice from the nation’s leading medical institutions. Board Review from M edscape is derived from the respected ACP Medicine CME program. A continually updated, evidence-based reference of adult internal medicine, ACP Medicine is also the first such comprehensive reference to carry the name of the American College of Physicians. At the end of each set of questions, we provide a cross-reference for further study in ACP Medicine. You can learn more about this publication on the Web at www.

An 81-year-old woman recently became ill and is now dying of metastatic cancer. Her physician is concerned that such an effort would be medically futile and extremely costly. Until recently, the patient had an active social life, which included regular participa- tion in many church activities.
The chest pain of acute peri- carditis typically develops suddenly and is severe and constant over the anterior chest purchase 50mg minocin overnight delivery. In acute pericarditis order 50mg minocin otc, the pain worsens with inspiration—a response that helps distinguish acute pericarditis from myocardial infarction buy cheap minocin 50 mg line. Low-grade fever and sinus tachycardia also are usually present buy 50mg minocin with mastercard. A pericardial friction rub can be detected in most patients when symp- toms are acute. Electrocardiographic changes are common in most forms of acute peri- carditis, particularly those of an infectious etiology in which the associated inflammation in the superficial layer of myocardium is prominent. The characteristic change is an ele- vation in the ST segment in diffuse leads. The diffuse distribution and the absence of recip- rocal ST segment depression distinguish the characteristic pattern of acute pericarditis from acute myocardial infarction. Depression of the PR segment, which reflects superficial injury of the atrial myocardium, is as frequent and specific as ST segment elevation and is often the earliest electrocardiographic manifestation. Analgesic agents, salicylates, or NSAIDs are often effective in reducing pericardial inflammation. Corticosteroids should be reserved for severe cases that are unresponsive to other therapy, because symptoms may recur after steroid withdrawal. The absence of a significant effusion on echocardiography is not evidence against acute pericarditis. Other symptoms include an erythematous rash, fatigue, and weight loss. Her medical history is significant for hyperten- sion. On physical examination, the patient’s temperature is found to be 100. A complete blood count shows anemia; the patient’s erythrocyte sedimentation rate (ESR) is ele- vated at 80 mm/hr. A transthoracic echocardiogram shows a 2 cm pedunculated mass in the left atrium. Which of the following is the most likely diagnosis for this patient? Cardiac myxoma Key Concept/Objective: To be able to recognize cardiac myxomas Cardiac tumors may be either primary or secondary and either benign or malignant. Metastatic cardiac involvement occurs 20 to 40 times more frequently than primary tumors. Eighty percent of all primary cardiac tumors are benign; myxomas account for more than half of these in adults. Myxomas consist of scattered stellate cells embedded in a mucinous matrix. They are found in the cavities of the heart, attached to the endocar- dial wall or heart valves by either a narrow stalk or a broader pedicle. Myxomas are most often manifested clinically by mechanical hemodynamic effects, which often simulate mitral or tricuspid stenoses or regurgitation. Intermittent obstruction of the valve orifice can lead to syncope or to remarkable changes in physical signs that are sometimes related to changes in body position. Another mani- festation is a constitutional disturbance consisting of fatigue, fever, erythematous rash, myalgias, and weight loss, accompanied by anemia and an increased ESR. The constitu- tional symptoms may be caused by production of interleukin-6 by the myxoma. Papillary fibroelastomas are small tumors, usually attached to cardiac valves; they can be a cause of cardioembolic stroke. Rhabdomyosarcoma is a malignant primary tumor of the heart. About 10% of patients who die of malignant disease have metastatic cardiac involvement, but the metastases produce symptoms in only 5% to 10% of the affected patients. The most frequent clinical manifestation is pericardial effusion with cardiac tamponade.
Vitiligo causes depig- mentation of skin and hair that develops in older children and young adults 50mg minocin fast delivery, usually those of darker skin color order 50mg minocin. Associated conditions include autoimmune endocrine disorders but not seizures or retardation discount minocin 50mg online. Piebaldism causes a white forelock in 90% of patients cheap minocin 50 mg fast delivery, as well as amelanotic macules on the trunk, extremities, and mucous membranes. These are pres- ent at birth and remain stable over time, unlike vitiligo, which develops later in life and is often progressive. A 24-year-old Hispanic woman has been using oral contraceptives and was treated with ciprofloxacin for a bladder infection several months ago. She presents with concerns about some spots on her face that she would like to have removed. The spots appeared suddenly over the past few weeks. On examination, the patient has blotchy, hyperpigmented, brown macules over the central face, without scaling or induration, involving the nose, nasolabial folds, upper lip, cheeks, and forehead. There are no lesions on the oral mucosa and no rashes elsewhere on her body. What is the most likely cause of this patient’s hyperpigmented lesions? Drug-induced sun sensitivity Key Concept/Objective: To recognize melasma in patients with risk factors and characteristic skin findings Melasma causes hyperpigmented macules in the central areas of the face. Risk factors for melasma include dark skin, female gender, oral contraceptive use, pregnancy, and sun exposure. Tinea faciei can cause hyperpigmented lesions on the face, but these are usually scaly, with annular accentuation of hyperpigmentation and central clearing. Lichen planus is usually quite itchy and usually occurs in locations such as the wrists, back, shins, and buccal mucosa, but it can also involve the eyelids, tongue, lips, or scalp. Lichen planus is usually more violaceous in color and contains fine, parallel, lacy white lines called Wickham striae. Lupus can cause a malar rash, which is usually erythematous rather than brown and usually confluent rather than blotchy, with some associated fine scaling. Like melasma, this classic malar rash can worsen with sun exposure, but it spares the nasolabi- al folds. Drug-induced sun sensitivity should also spare the nasolabial folds and upper lip because these areas receive less sun exposure than do other areas of the face. A 76-year-old man is being evaluated for osteoporosis. A dual-energy absorptiometry scan showed a decrease in bone mineral density consistent with osteoporosis. The serum concentration of total testosterone is in the low-normal range. Which of the following is the most accurate description of the physiologic changes in testosterone seen with senescence? With aging, there is a large decrease in serum total testosterone level; this decrease is related to a decrease in the concentration of sex hor- mone-binding globulin (SHBG) B. With aging, there is a relatively small decrease in serum total testos- terone level; free testosterone decreases to a greater degree; SHBG increases C. With aging, serum estradiol concentration increases secondary to a decrease in the total testosterone concentration D. With aging, the total testosterone level remains unchanged Key Concept/Objective: To understand the physiologic changes in testosterone levels seen with aging As men age, their serum total testosterone concentration decreases. The decrease in the serum concentration of total testosterone is very gradual and of relatively small magni- tude.
