Total cholesterol (mmol/L) Initiation of pharmacotherapy is dependent on the assessment of <4. The chronic hyperglycemia of diabetes is associated with long-term damage, dysfunction, and failure of different organs, especially the eyes, kidneys, nerves, heart, and blood vessels. These range from autoimmune destruction of the pancreatic b-cells with consequent insulin deficiency to abnormalities that result in resistance to insulin action. The basis of the abnormalities in carbohydrate, fat, and protein metabolism in diabetes is deficient action of insulin on target tissues. Deficient insulin action results from inadequate insulin secretion and/or diminished tissue responses to insulin at one or more points in the complex pathways of hormone action. Impairment of insulin secretion and defects in insulin action frequently coexist in the same patient, and it is often unclear which abnormality, if either alone, is the primary cause of the hyperglycemia. Symptoms of marked hyperglycemia include polyuria, polydipsia, weight loss, sometimes with polyphagia, and blurred vision. Impairment of growth and susceptibility to certain infections may also accompany chronic hyperglycemia. Acute, life-threatening consequences of uncontrolled diabetes are hyperglycemia with ketoacidosis or the nonketotic hyperosmolar syndrome. Long-term complications of diabetes include retinopathy with potential loss of vision; nephropathy leading to renal failure; peripheral neuropathy with risk of foot ulcers, amputations, and Charcot joints; and autonomic neuropathy causing gastrointestinal, genitourinary, and cardiovascular symptoms and sexual dysfunction. Patients with diabetes have an increased incidence of atherosclerotic cardiovascular, peripheral arterial, and cerebrovascular disease. Hypertension and abnormalities of lipoprotein metabolism are often found in people with diabetes.

The procoagulant forces include platelet adhesion and Platelet adhesion results in subsequent platelet activaaggregation and fibrin clot formation; anticoagulant tion and aggregation. This process is enhanced and forces include the natural inhibitors of coagulation and amplified by humoral mediators in plasma. Under normal circumstances, hemostasis is nephrine, thrombin); mediators released from activated regulated to promote blood fiow; however, it is also platelets. The major components of which they secrete contents that further promote aggrethe hemostatic system, which function in concert, are gation and inhibit the naturally anticoagulant endothelial (1) platelets and other formed elements of blood, such cell factors. During platelet aggregation (platelet-platelet as monocytes and red cells; (2) plasma proteins (the interaction), additional platelets are recruited from the coagulation and fibrinolytic factors and inhibitors); and circulation to the site of vascular injury, leading to the (3) the vessel wall itself. This receptor is the key mediator of platelet the high levels of shear stress that would tend to detach aggregation, so it has become an effective target for them with the fiow of blood. Thromand activation through the classic extrinsic pathway but bin is a multifunctional enzyme that converts soluble with critically important amplification through elements plasma fibrinogen to an insoluble fibrin matrix. The critical cell membrane compocomponents of the vessel wall, such as smooth-muscle nents, acidic phospholipids, are not normally exposed cells and fibroblasts. However, when microparticles, presumably shed from cells including platelets, monocytes, and endothelial cells are activated monocytes and platelets. Coagulation requires calcium (not bin formation and subsequent conversion of fibrinogen to shown) and takes place on phospholipid surfaces, usually the fibrin. Fibrinogen is a trinoduPlasma lar structure consisting of 2 D domains and 1 E domain. These mechanisms operate to preserve blood increases by a factor of several thousand in the presence fluidity and limit blood clotting to specific focal of heparin.

The lysine-binding 25 activated protein C by a specific mutation at its target sites of plasmin (and plasminogen) permit it to bind to cleavage site in factor Va (factor V Leiden), lead to hyperfibrin, so that physiologic fibrinolysis is fibrin specific. The sites of plasmin cleavage of fibrin are the same as those in Any thrombin that escapes the inhibitory effects of the fibrinogen. However, when plasmin acts on covalently physiologic anticoagulant systems is available to convert cross-linked fibrin, D-dimers are released; hence D-dimers fibrinogen to fibrin.

Chronic specific (granulomatous) endometritis is most often tuberculous in etiology treatment 4 pimples generic zerit 40 mg with amex. Causes may include retrograde dissemination of endometrial fragments through fallopian tubes during menstruation treatment strep throat discount zerit amex, with implantation on the ovary or other peritoneal structures medicines 604 billion memory miracle zerit 40 mg otc, or blood-borne or lymphatic-borne dissemination of endometrial fragments symptoms 5 dpo order zerit with american express. The condition is characteristically responsive to hormonal variations of the menstrual cycle. Menstrual-type bleeding occurs into the ectopic endometrium, resulting in blood-filled, or so-called chocolate, cysts. Endometriosis occurs most often in the pelvic area; the ovary is the most common site, followed by the uterine ligaments, rectovaginal septum, pelvic peritoneum, and other sites. The cause is usually excess estrogen stimulation, which in turn may be caused by anovulatory cycles, polycystic ovary disease, estrogen-secreting ovarian tumors, such as granulosa cell tumor, and estrogen replacement therapy. It is sometimes a precursor lesion of endometrial carcinoma; the risk of carcinoma varies with the degree of cellular atypia. Simple (cystic or mild) hyperplasias have a low malignant potential, while higher grade (atypical) hyperplasias have a greater malignant potential. This is the most common uterine tumor and the most common of all tumors in women; the incidence is increased in women of African lineage. They often increase in size during pregnancy, and they almost always decrease in size following menopause. The tumors may lie within the myometrium (intramural) or in subendometrial (submucous) or subperitoneal (subserous) locations. Leiomyomas, especially if subendometrial, often manifest clinically by menorrhagia (increased menstrual bleeding). It arises de novo and is almost never caused by malignant transformation of a leiomyoma. This well-differentiated type I endometrial cancer shows grossly discernible polypoid growth within the uterine cavity with superficial myometrial invasion (A). Microscopically, it is comprised of well-formed, closely packed glands with cytologic atypia which are still reminiscent of normal endometrium. Type I tumors are more common, occur mainly in premenopausal and perimenopausal women, and carry a good prognosis. Endometrial cancers may appear in these patients before gastrointestinal malignancies, and current evidence suggests that the appearance of endometrial cancer in patients fi50 and/or with a strong family history should prompt investigation for mismatch repair defects. Endometrial stromal malignancies are rare and include pure stromal neoplasms (endometrial stromal sarcoma) and mixtures of stromal and endometrial elements (adenosarcoma). This disorder is most often associated with inflammation of the ovaries and other adjacent tissue (pelvic inflammatory disease). Salpingitis can result in pyosalpinx, a tube filled with pus, or hydrosalpinx, a tube filled with watery fluid; it may also result in a tubo-ovarian abscess. Historically, adenocarcinoma of the fallopian tube was usually considered to be extension from a primary elsewhere and indeed is, in the vast majority of cases, associated with bulky tumors extending from the ovary or endometrium. However, recent evidence suggests that the fallopian tube may actually represent the site of origin for serous ovarian carcinomas. It is symptomatically associated with menstrual irregularity, occasionally with intraperitoneal hemorrhage. This cyst results from gonadotropin stimulation; it can be associated with choriocarcinoma and hydatidiform mole. This cyst is a blood-containing cyst resulting from ovarian endometriosis with hemorrhage. Polycystic ovary syndrome may be associated with insulin resistance with an increased risk of diabetes mellitus. Morphologic characteristics include the following: (1) Markedly thickened ovarian capsule (2) Multiple small follicular cysts containing a granulosa cell layer and a luteinized theca interna (3) Cortical stromal fibrosis with islands of focal luteinization B. This benign cystic tumor is lined with cells similar to fallopian tube epithelium. It accounts for approximately 20% of all ovarian tumors and is frequently bilateral. This tumor of intermediate malignant potential has a peak incidence in women aged 20 to 50, is usually curable by surgery, is typically comprised of papillary fronds with moderate atypia and some mitotic activity, and lacks significant invasion (although very focal microinvasion may be present). This malignant tumor accounts for approximately 50% of ovarian carcinomas and is frequently bilateral (Figure 19-4). This benign tumor is characterized by multilocular cysts lined by mucus-secreting columnar epithelium and filled with mucinous material. Like their serous counterparts, these tumors typically occur in younger women and are confined to the ovary. A search for an appendiceal primary should always be performed in the presence of pseudomyxoma peritonei, even if ovarian tumors are present, because the ovarian tumors may represent metastases. Often, synchronous endometrial primaries are identified in patients with ovarian tumors of this histologic type. They are the most common ovarian tumors seen in association with endometriosis, although the connection between these two entities is not well elucidated. They are characterized by small islands of epithelial cells resembling bladder transitional epithelium interspersed within a fibrous stroma. They account for most ovarian tumors occurring in women younger than 20 years of age. Endodermal sinus (yolk sac) tumor (1) this tumor resembles extraembryonic yolk sac structures. Teratomas (1) these tumors characteristically demonstrate tissue elements derived from two or three embryonic layers. This aggressive malignant tumor includes immature cellular elements, which are most often primitive neural elements (b) Mature teratoma (dermoid cyst). This accounts for approximately 20% of ovarian tumors and 90% of germ cell tumors. The cyst is lined by skin, including hair follicles and other skin appendages; other elements often include bone; tooth; cartilage; and gastrointestinal, neurologic, respiratory, and thyroid gland tissues. This cyst contains only a single tissue element; for example, the most common is struma ovarii, which consists entirely of thyroid tissue and can be hyperfunctional, resulting in hyperthyroidism. Tumors of ovarian sex cord-stromal origin account for a small percentage of ovarian neoplasms. Thecoma-fibroma group of tumors (1) Fibroma (a) this solid tumor consists of bundles of spindle-shaped fibroblasts. Tumors metastatic to the ovary account for approximately 5% of all ovarian tumors. These tumors are frequently of gastrointestinal tract, breast, or endometrial origin. They are called Krukenberg tumors when ovaries are replaced bilaterally by mucinsecreting signet-ring cells; the site of origin is often the stomach (Figure 19-7). The malignant cells are most often of gastric origin and are mucin-producing signet-ring cells. Placenta accreta is attachment of the placenta directly to the myometrium; the decidual layer is defective. This is predisposed by endometrial inflammation and old scars from prior cesarean sections or other surgery. It is manifested clinically by impaired placental separation after delivery, sometimes with massive hemorrhage. Placenta previa is an attachment of the placenta to the lower uterine segment, partially or completely covering the cervical os. This disorder is characterized by severe hypertension that most often occurs de novo during pregnancy or complicates preexisting hypertensive disease. Toxemia characteristically occurs during the third trimester, most often in the first pregnancy, and affects the kidneys, liver, and central nervous system. Preeclampsia, a milder form of toxemia characterized by hypertension, albuminuria, and edema. This condition is characterized by sudden peripartal respiratory difficulty, progressing to shock and often to death. It is marked by masses of debris and epithelial squamous cells in the maternal pulmonary microcirculation. This should not be confused with the amniotic fluid aspiration syndrome, which is a disease of the neonate, not of the mother.
