It is recommended that all diabetic pregnant women undergo a baseline retinal check as a screen- ing procedure in the early stages of pregnancy in the non-pathological and physiological frst trimester, with any follow-up tailored accord- processes most commonly encountered ing to the fndings. If there is no retinopathy at this The cornea is the commonest tissue which may alter examination, a three monthly check of the retina is at any stage of pregnancy, and fuctuations in refrac- recommended, which is usually adequate if the dia- tion may occur as a result.

Ophthalmologists are sometimes requested to do a Some changes may occur in the lens too, where routine check for hypertensive retinopathy. Tis is there may be an alteration in accommodation and not required if blood pressure control is good and the refractive index, leading to similar fuctuations in vision, as with the cornea. Tese are easily examined by using a focal light source, and the patient may be quite symptomatic regarding these, as they may cause some discomfort of the eye. The lids may show some increased pufness and chloasma, whereas the con- junctiva may become a little more hyperaemic, caus- ing an increased redness. Neither the redness, if mild, nor dry eye necessarily indicates a conjuncti- vitis or infection, and both may be relieved by simple lubricants with no other requirement for medication. De novo conditions Pre-eclampsia and eclampsia The ophthalmologist does have a role to play when there is the development of pre-eclampsia if any eye symptoms and signs develop. Many of these women will show retinal vascular changes, mainly those of vasoconstriction. Symptoms that patients with pre-eclampsia may present with are: blurring of vision or decreased vision; photopsia or light sensitivity and odd fashes of light; isolated feld defects or scotomata; intermittent diplopia of a variable nature; severe visual loss and possibly even blindness in severe cases. The pathology is due to: cardiovascular changes; haematologic changes; hepatic and renal impairment; neurological manifestations; Figure 3 Diabetic microaneurysms and exudates (arrow).

During the intestinal phase, protein digestion products in the duodenum stimulate gastric acid secretion through the action of the circulating amino acids on the parietal cells.

It is related to activation of stress-operated calcium channels in the smooth muscle itself that open with stretch, thereby increasing calcium entry into the cells and causing contraction of vascular smooth muscle. Niacin plays an important role in coenzymes that participate in many oxidation–reduction reactions involving hydrogen transfer. Water always moves from the region of low osmotic pressure (low solute concentration) to the region of high osmotic pressure (high solute concentration).

Solute movement dissipates the gradient and an equilibrium state is eventually reached at which net movement ceases. Passive transport of lipid-soluble solutes can occur without a carrier protein (diffusive membrane transport). Passive transport of ions occurs through ion channel proteins, and polar hydrophilic solutes must use a carrier protein.

Outline the effects of thyroid hormones on central nervous system development infection knee pain purchase cefadroxil with amex, growth hormone release antibiotics for acne marks order discount cefadroxil, and target tissues such as bone bioban 425 antimicrobial generic 250 mg cefadroxil with amex. Explain how thyroid hormone regulates basal metabolic rate and intermediary metabolism. Predict the effects of excess thyroid hormone and thyroid hormone deficiency on metabolic rate, mental status, and body weight. The cell not only meets its basic metabolic “housekeeping” needs but also remains poised to do its own special work in the body, such as conducting nerve impulses and contracting, absorbing, and secreting. During its life span, the cell continues to make the enzymatic and structural proteins that ensure the maintenance of an appropriate rate of metabolism. The thyroid hormones, thyroxine (T )4 and triiodothyronine (T )3, play key roles in the regulation of body development and govern the rate at which metabolism occurs in individual cells. These hormones are not essential for life, but without them, cellular housekeeping moves at a slower pace, eventually influencing the ability of individual cells to carry out their physiologic functions. The thyroid hormones exert their regulatory functions by influencing gene expression and affecting the developmental program and amount of cellular constituents needed for the normal rate of metabolism. A band of thyroid tissue, the isthmus, lies just below the cricoid cartilage and connects the two lobes. The thyroid gland is one of the largest endocrine glands in the body, weighing about 20 g in a healthy adult. Each lobe of the thyroid receives its arterial blood supply from a superior and an inferior thyroid artery, which arise from the external carotid and subclavian arteries, respectively. Blood leaves the lobes of the thyroid by a series of thyroid veins that drain into the external jugular and innominate veins. This circulation provides a rich blood supply to the thyroid gland, giving it a higher rate of blood flow per gram than even that of the kidneys. The thyroid gland receives adrenergic innervation from the cervical ganglia and cholinergic innervation from the vagus nerves. The adrenergic system can also affect thyroid function by direct effects on the cells. Follicles within the thyroid gland synthesize and secrete thyroxine and triiodothyronine. The lobes of the thyroid gland consist of aggregates of many spherical follicles, lined by a single layer of epithelial cells (Fig. Microvilli cover the apical membranes of the follicular cells, which face the lumen. Tight junctions, which provide a seal for the contents of the lumen, connect the lateral membranes of the follicular cells. The basal membranes of the follicular cells are close to the rich capillary network that penetrates the stroma between the follicles. The colloid is a solution composed primarily of thyroglobulin (Tg), a large protein that is a storage form of the thyroid hormones. T and T are iodinated derivatives of the amino acid4 3 tyrosine, formed by an ether linkage between the phenyl rings of two iodinated tyrosine molecules. T contains four iodine atoms on the 3, 5, 3′, and 5′ positions of the thyronine ring structure, whereas4 T has only three iodine atoms, at ring positions 3, 5, and 3′ (see 3 Fig. In addition to the epithelial cells that secrete T and T, the wall of the thyroid follicle contains a few4 3 parafollicular cells (see Fig. The parafollicular cell is usually embedded in the wall of the follicle, inside the basal lamina surrounding the follicle, and its plasma membrane does not form part of the wall of the lumen. Follicular cells synthesize and store iodinated thyroglobulin within the follicle. Rather, T and T are4 3 4 3 formed by chemical modification of tyrosine residues in the peptide structure of Tg as the follicular cells secrete it into the follicle lumen. Thus, the T and T formed by this chemical modification are actually4 3 part of the amino acid sequence of Tg.
