If the adenoidectomy is done it will cause hypernasality and regurgitation from the nose cheap mildronate online amex medicine urinary tract infection. However if necessary do partial adenoidectomy: remove the part against the nose but keep the oral part because it supports the defect in the soft palate order mildronate with paypal treatment yeast infection home. Indications for tonsillectomy: 1 If recurrent: 6-7 attacks per year generic 250 mg mildronate with amex medications reactions, 4 attacks per year for 2 years, or if 3attacks per year for 3 years. Abscess collection between lateral wall and capsule, so the tonsil is pushed to the midline, pushing the uvula also. Treat it by incision and drainage, but if recurrent tonsillitis and peritonsillar abscess you treat the abscess, wait for 6 weeks then do the tonsillectomy. Hot technique: laser or lasek, suction diaythermy Adenoids can reoccur because they do not have capsules but not commonly Complications of Tonsillectomy: 1. Hemorrhage (most common) o Primary hemorrhage: Bleeding occurring during the surgery ¾ Causes 1. Packing o Reactionary hemorrhage: within the first 24 hours postoperative period ¾ Causes 1. We need to instruct them about the food habits needed postop to help with the healing process. The caregiver needs to be well informed about the food, the antibiotics and the analgesia (they need regular analgesia). They also need to be well informed about the slough tissue so that they would not think it’s a complication and change the patient’s medications or worry. Signs and Symptoms: fever, otalgia, odynophagia, uvular deviation, trismus, and drooling of saliva, the patient looks sick and dehydrated. The abscess may rupture causing aspiration inside the mouth; the puss will go into the airway causing obstruction and the other complications. Dry heat, smoking, alcohol), reflux, esophagitis chronic mouth breathing ,allergy granulomatoues disease connective tissue disease , malignancy Signs and Symptoms: Constant mouth clearing, dry throat pharyngeal crusting, thick granular wall Treatment: address underlying etiology 13. Intratemporal part: From the Internal Auditory Meatus (association with vestibulocochlear nerve). Extracranial part: After it leaves the temporal bone through the Stylomastiod foramen, it goes through the parotid gland. The other secreto-motor fibers leave the vertical part of the facial nerve through the Chorda Tympani, which crosses the middle ear. The Chorda Tympani then joins the Lingual nerve and innervates the two salivary glands: the submandibular gland and sublingual gland. Taste: takes the same course of the Parasympathetic but in the opposite way (from peripheral to central). For Example: If the lesion is above the level of the chorda tympani> patient will loose the function of chorda Tympani he will have dryness and loose of taste sensation. Pathologies of facial nerve injury: Facial nerve paralysis could be: 1 Conduction block (Neuropraxia) due to mild trauma, nerve is affected functionally only and there is no degeneration anatomically. A) Partial facial paralysis: Being partial means that the nerve fibers are in continuity and recovery is expected by conservative treatment (e. B) Complete facial paralysis: If it is due to neuropraxia, recovery is expected by conservative treatment. Test the lacrimation function Stapedial reflex Taste sensation Causes of Facial nerve paralysis: we can distribute it as Anatomical or Pathological Anatomical: -Intracranial causes -Cranial (intratemporal) causes -Extracranial causes Pathological: • Congenital: Birth trauma • Traumatic: Head and neck injuries & surgery • Inflammatory: O. B-Temporal bone fracture: 1-Longitudinal More common, Less severe, might cause conductive hearing loss, usually does not affect facial nerve. Edema: will lead to partial paralysis Transaction of the nerve: will lead to complete paralysis.
Adverse effects: excessive dose cause massive cardiac arrest discount 250mg mildronate with mastercard symptoms 9 days past iui, dizziness cheap 250mg mildronate with amex medicine jewelry, drowsiness cheap mildronate 500 mg mastercard medicine 2355, seizures, etc. It is used in ventricular ectopic beats in patients with normal left ventricular function. Beta blockers may potentiate the negative inotropic action of other antiarrhythmics. Therapeutic uses: This is useful in tachyarrhythmias, in pheochromocytoma and in thyrotoxicosis crisis. It is also useful in patients with atrial fibrillation and flutter refractory to digitalis. The main adverse effects of this drug are anorexia, nausea, abdominal pain, tremor, hallucinations, peripheral neuropathy, A. It is absolutely contraindicated in patients on beta blockers, quinidine or disopyramide. Class V drugs: Digoxin causes shortening of the atrial refractory period with small doses (vagal action) and a prolongation with the larger doses (direct action). This action is of major importance in slowing the rapid ventricular rate in patients with atrial fibrillation Diuretics Diuretics are drugs, which increase renal excretion of salt and water: are principally used to remove excessive extracellular fluid from the body. In order to understand the action of diuretics it is important to have some knowledge of the basic processes that take place in the nephron (unit structure of kidney. Approximately 180 liters of fluid is filtered from the glomerulus into the nephron per day. There are three mechanisms involved in urine formation 64 a) glomerular filtration b) tubular reabsorption c) Tubular secretion. Classification of diuretics: Most of the diuretics used therapeutically act by interfering with sodium reabsorption by the tubules. Thiazide diuretics act by inhibiting NaCl symport at the distal convoluted tubule. Adverse effects: epigastric distress, nausea, vomiting, weakness, fatigue, dizziness, impotence, jaundice, skin rash, hypokalemia, hyperuricemia, hyperglycaemia and visual disturbance. Loop diuretics: Loop diuretics like frusemde inhibit Na K – 2Cl symporter in the ascending limb. Adverse effects: Hypokalemia, nausea, anorexia, vomiting epigastric distress, fatigue weakness muscle cramps, drowsiness. Therapeutic uses: acute pulmonary edema, edema of cardiac, hepatic and renal disease. Hypertension, cerebral edema, in drug overdose it can be used to produce forced diuresis to facilitate more rapid elimination of drug. Potassium sparing diuretics mechanism of action: Potassium sparing diuretics (spironolactone, triamterene, amiloride) are mild diuretics causing diuresis by increasing the excretion of sodium, calcium and bicarbonate but decrease the excretion of potassium. Hyponatraemia 65 Therapeutic uses: used with conjunction with thiazides or loop diuretics in edema due to, cardiac failure nephrotic syndrome and hepatic disease. Carbonic anhydrase inhibitors: these drugs like acetazolamide inhibit the enzyme carbonic anhydrase in renal tubular cells and lead to increased excretion of bicarbonate, sodium and potassium ions in urine. Main adverse effects of these agents are drowsiness, hypokalemia, metabolic acidosis and epigastric distress. Osmotic diuretics: these drugs like mannitol and glycerine (glycerol) are freely filtered at the glomerulus and are relatively inert pharmacologically and undergo limited reabsorption by renal tubule. These are administered to increase significantly the osmolality of plasma and tubular fluid.

Mutagens in urine samples repetitively from municipal refuse incinerator workers and water treatment workers. Genetic instability of cancer cells is proportional to their degree of aneuploidy. Retrotransposons regulate host genes in mouse oocytes and preimplantation embryos. Science, Another self-regeneration mechanism is autophagy, by which Vol 288, Issue 5466, 669-672 , 28 April 2000. Low-Dose Exposure to X-Rays Induces Specific Gene Regulations in Normal Human Keratinocytes. Molecular Basis be distinguished from normal ones in that they had Although the environment can be controlled to reduce cancer abnormal numbers of chromosomes (see inset at left). The leading hypothesis on the be changed by altering the genome itself towards increased nature of cancer suggests that a variety of gene stability. Therefore, cancer is a disease that needs to be fought changes can induce genetic instability, and that ongoingly in species that show genomic adaptability. Ames has shown the deficiencies in vitamins B12, B6 or that cancer cells are genetically “abnormal”. Given a system as complex as the genome, the “normal” cells of the body may be more remarkable than the cancer cells. To a point, stable genomes sacrifice adaptability and variability, a hallmark of bacteria, for the benefit of building coherent multi cellular organisms, presumably an advantage to establish immunity. The retinoblastoma protein, for example, is central to the process of cell proliferation, activating the genes for cell division. An interesting property of this protein is that it is active in a wide variety of cellular processes, and interacts with more than 100 other proteins. Contaminated injections from health care sets the media into a frenzy of reporting to avid readers or listeners, and governments into regulatory responses. For example, a statement many years ago by John Higginson passage of time, or in succeeding generations, rates tend to that 80% of all cancers could be attributed to the approach those of the native-born in the country of adoption, "environment" was interpreted by the press and the reading pointing to the importance of environmentally determined public to mean that things outside their control were the root hormonal or dietary causes. Higginson meant "environment" to include Some controllable causes of cancer are smoking and drinking lifestyles, diet, drugs and workplace exposures in addition to alcohol. In the case of alcohol, it is known that alcohol contaminants in the air, soil, and water (F14. The is supported by international observations on cancer incidence enzyme also activates procarcinogens such as nitrosamines. It is estimated that 30% of cancers could be eliminated through dietary intervention.
The bladder has a strong muscular wall and is able to receive about 500 ml of urine purchase mildronate mastercard medications that cause hair loss. This muscular wall is composed of three layers of smooth muscle collectively known as the detrusor muscle mildronate 500mg with visa symptoms nervous breakdown. Note that although located in the pelvis discount mildronate 500 mg otc medicine guide, the bladder can be palpated through the anterior abdominal wall, immediately above the pubic symphysis, when completely full. Classically, the bladder is described as having a pyramidal shape, has an apex (connected to the umbilicus by the median umbilical ligament, a remnant of the urachus), a base (triangular posterior surface), and a neck (inferiorly). Note that the neck opens in the urethra (prostatic urethra in male) and that at the neck, the circular muscular fibers thickened to form the sphincter vesicae. This sphincter, under autonomic control, regulates the release of urine from the bladder. Observe also that the neck is anchored to the walls of the pelvis by the pubovesical ligaments in female and puboprostatic ligament in male. The inside of the bladder muscular wall is covered by a mucous membrane forming folds in the empty bladder. The smooth portion of the mucous membrane found below a line passing between the two ureteric orifices on the posterior wall is called the trigone. In this area, the mucous membrane do not form folds, even in the empty bladder, due to the fact the membrane is tightly adherent to the underlying muscular layer. The superior surface and the upper part of the posterior surface of the bladder is covered by peritoneum. Note that in female, the neck of the bladder (inferiorly) rests on the upper surface of the urogenital diaphragm whereas in male the neck of the bladder lies on the upper surface of the prostate. Laterally, in both the male and the female, the inferolateral surfaces are related anteriorly to the retropubic fat pads and posteriorly to the obturator internus above and the levator ani below. Note that in males, the two vas deferens and the two seminal vesicles can be found on the inferior aspect of the posterior surface of the bladder, superior to the prostate (see later in this lecture). The superior and inferior vesical arteries (branches of the internal iliac arteries) provide blood supply to the bladder in both males and females. In both males and females, the venous drainage is by the vesical venous plexus draining into the internal iliac vein through the superior and inferior vesical veins. Note that in males, the vesical venous plexus communicates with the prostatic venous plexus. In terms of innervation, the bladder is under the control of the inferior hypogastric plexuses. The sympathetic fibers originate from the first and second lumbar ganglion, synapse in the inferior hypogastric plexuses and end in the bladder. They inhibit contraction of the detrusor and stimulate the closure of the sphincter vesicae. The parasympathetic fibers pass through the pelvic splanchnic nerves (S2-4), and also synapse in the inferior hypogastric plexuses before innervating the bladder. They stimulate contraction of the muscular wall and inhibit the action of the sphincter vesicae. Most of the afferent (sensory) fibers are believed to reach the central nervous system through the pelvic splanchnic nerves, with only st a few passing through the sympathetic fibers (1 nd and 2 lumbar splanchnic). This muscle, innervated by the perineal branch of the pudendal nerve, compresses the urethra to stop the flow of urine out of the bladder. In male, as already discussed, the urethra is divided in 3 parts, the prostatic, membranous and penile urethra. Beginning at the neck of the bladder, it passes through the prostate and then becomes the membranous urethra.
