In the last couple of decades a number of diseases thought to be of unknown causes have been proven to result from food borne infections 600 mg neurontin with mastercard. In developing countries like Ethiopia in particular discount neurontin 400 mg online, the problem attains great proportions due to many reasons neurontin 100mg; basic among which are poverty 800mg neurontin mastercard, poor environmental sanitation and lack of public health awareness discount neurontin 300 mg with mastercard. In these modern day times in which food is usually not consumed immediately following and/or at the site of production purchase 600 mg neurontin, the risks of food-borne diseases are becoming increasingly important; the concern is obviously much more in areas where food storage and preparation safety measures are far from optimum. The extent of diagnostic evolution of food borne diseases can be based on history, clinical features, environmental assessment and laboratory investigations. Prevention and control of food–borne diseases, regardless of the specific cause, are based on the same principles: a. Specific modes of intervention vary from area to area depending on environmental, economic, political, technology and socio cultural factors. Place a drop of physiological saline in the center of the left half of the slide and place a drop of Dobell’s iodine solution in the center of the right half of the slide. With an applicator stick, pick up a small portion of the feces (about 2mg which is as much as the size of a match head) and put on the drop of saline. Mix the feces with the two different drops using the applicator stick to form a homogeneous suspension. Examine the saline preparations using the 10x objective for trophozoites (vegetative/motile forms) and cysts as well as oocyst of intestinal protozoa and for any ova or larva of helminthes. Examine the iodine suspension with 40 objective for better identification of the cyst stages of protozoa (iodine will stain the nuclei and the glycogen mass of the cyst.

Nuclear family is defined as ‘’ a family consisting of a married couples and their children; the children can be born or adopted’’. For practical reasons, it may be sound to distinguish: ♦ The childbearing unit, nuclear or one parent family, where the genetic factors are prominent. It could be defined as: A quality of life, which involves social, mental and biological fitness on the part of the individual, which results from adaptations to the environment. The summary of different views conceptualises health to be multidimensional and inclusive of many components and many different aspects of one’s life.

The male sex accessory glands are the paired seminal vesicles generic 400 mg neurontin, the prostate gland buy 400mg neurontin mastercard, and the paired bulbourethral glands buy discount neurontin 800mg on line. The duct of each seminal vesicle unites with the ampulla of a ductus deferens to form a common ejaculatory duct neurontin 300 mg visa. The prostate gland surrounds the ejaculatory duct and the prostatic urethra order neurontin 600mg line, and secretes into the latter generic 400mg neurontin. The mediastinum (not visible on this slide) is the mass of acidophilic connective tissue at one 67 pole through which the major vessels enter and leave the testis. At higher magnification identify the germinal elements (spermatogonia, spermatocytes and spermatids) and Sertoli cells in the seminiferous tubules. Only the Sertoli cells and spermatogonia (usually with interphase nuclei) rest on the basement membrane. The larger primary spermatocytes lie on the luminal side of the Sertoli cells and are frequently in some stage of the prolonged prophase of the first meiotic division. Beneath the basement membrane of the tubules note the myoid cells (myoepithelium) with their pale- staining elongated nuclei. In the interstitium (between the seminiferous tubules) identify Leydig cells, which are large eosinophilic cells. It is a coiled tube lined by pseudostratified epithelium with long microvilli (non-motile stereocilia). Note: For the histological characteristics of the efferent ductules see examples in textbooks or online. Note that there are no discrete secretory alveoli in the seminal vesicle; instead the entire lining membrane of the saccular gland is thrown into a series of complex, high, thin folds. The lining epithelium is generally simple columnar or pseudostratified, and basal cells 68 are frequently seen, as in the epididymis and ductus deferens. The seminal vesicle is embryologically derived from the ductus deferens, and like the latter, it has a prominent muscularis. The acidophilic secretory material in the lumen of the gland is rich in fructose, thought to serve as an energy source for spermatozoa following ejaculation. Also evident are the elongate tubules forming the parenchyma of the gland and the dense fibrous connective tissue capsule. Compare its transitional epithelium with the epithelium lining the ducts and glands of the prostate, which can be cuboidal, columnar or pseudostratified. The tubulo-alveolar glands of the prostate are embedded in an abundant stroma of fibro-elastic connective tissue, which is interlaced with strands of smooth muscle. Fixation is much better in the H & E sections, and it should be studied for the structure of the lining epithelium of the glands. Examine the central penile urethra and the surrounding blood-filled vascular sinuses that comprise the erectile tissue of the corpus spongiosum. Note that the lining epithelium of the penile urethra has a stratified columnar or stratified cuboidal appearance. Study the erectile tissue surrounding the urethra and observe that the trabeculae between blood sinuses contain smooth muscle and connective tissue fibers. The connective tissue capsule surrounding the corpus spongiosum is not as thick as that surrounding the corpora cavernosa. At low power note the general division of the ovary into an outer cortex containing follicles in various stages of development and an inner medulla containing numerous blood vessels and dense fibrous connective tissue. Identify; Lining epithelium (classically called “germinal epithelium”) - a simple cuboidal covering the ovary, continuous with the mesothelium of the peritoneum. These are growing follicles Secondary (antral) follicles - 1 oocyte surrounded by granulosa cells among which fluid-filledo spaces are coalescing into a single space, or antrum. Outside the basal lamina of the granulosa layer, the theca has differentiated into a theca interna and a theca externa. Atresia is often first recognized in the granulosa cells as the nuclei become apoptotic and there is a loosening of the cells. Corpus luteum – Following ovulation follicular cells (both granulosa and luteal) fold into the empty follicle and undergo luteinization.

Determining the severity of Incontinence Incontinence It is important to make a clinical Symptoms of Urinary Incontinence attempt to determine the severity are notoriously diffcult to of the incontinence symptoms proven 300mg neurontin. The International woman could be asked to quantify Continence Society defnes the symptoms on a scale of 0 to this as the “involuntary loss I0. The Urinary urgency number of incontinence episodes This is the compelling desire to per day can also be indicative of void which is diffcult to defer. It must be differentiated from urinary urge which is a normal Symptoms of voiding desire to void which can be dysfunction 4 These symptoms are not as common in women as in men Prolapse symptoms but if present, should prompt Women with prolapse have a the appropriate investigation of broad range of symptoms. Most women • Straining to void will complain of a bulge or a lump, • Incomplete Emptying whilst others will describe either • Post- Micturition dribbling discomfort or a burning sensation.

There are now many thousands of chemical substances used in industry ranging from metals & inorganic compounds which risk people who work with it buy cheap neurontin 100 mg line. Heavy metal poisoning Some metals such as iron are essential for life buy neurontin 800 mg otc, while others such as lead are present in all organisms but serve no useful biologic purpose cheap 600 mg neurontin free shipping. Some of the oldest diseases of humans can be traced to heavy metal poisoning associated with metal mining purchase 100mg neurontin with amex, refining and use 100mg neurontin otc. Lead Poisoning Lead poisoning is one of the oldest occupational and environmental diseases in the world purchase neurontin 100 mg visa. Despite its recognized hazards, lead continues to have widespread commercial application (like ingested lead paints, pica, and lead pipes etc…). Environmental lead exposure, ubiquitous by virtue of the anthropogenic distribution of lead to air, water and food, has declined considerably due to diminished use of lead in gasoline and other applications. Lead is slowly but consistently absorbed via the 52 Toxicology respiratory and gastrointestinal tracts. Lead exerts multi systemic toxic effects through at least three mechanisms by; o Inhibiting enzyme activity (e. Lead interference with the biosynthesis of heme The sign and symptoms of lead poisoning may include anorexia, apathy, behavioral changes, persistent vomiting, convulsions (acute poisoning) & ataxia, wrist & ankle drop, chronic nephritis (chronic poisoning) Laboratory findings A. It is not present in iron deficiency anemia so it is valuable for differentiating the two forms of anemia. B) Serum Lead level Levels of 30-60µg/dl are regarded as significant for lead toxicity. Levels below the toxic range do not rule out toxicity because 90% of lead is stored in bone. Unexpectedly high lead levels may be due to contamination of the blood specimen with lead prior to laboratory analysis. Protoporphyrin accumulates as a result of the lead inhibition of the enzyme ferrochelases, which binds to porphyrin, forming hemoglobin. Lead inhibition of the enzyme coproporphyrinogen oxidase has been proposed as a cause for increased coproporphyrin. Spot 50 µl of acidified solution on to phase-separating filter- paper and add 50 µl of sodium rhodizonate solution. However, the test is not specific: barium salts give a brown colour and a number of other metals also give coloured complexes. Sensitivity Lead, 2 mg/l Quantitative tests Principle 56 Toxicology Whole blood that represents calibrators, controls, or victim specimens is mixed with ammonium phosphate and Triton X-100 to prepare it for graphite furnace atomic absorption analysis. The final step of analysis causes vaporization of lead, which absorbs energy at the 283. Absorbance of energy at this wavelength is specific for lead and proportional to its concentration. Add 10 µL of matrix modifier to 10µL of each sample and inject into the L’vov platform. Repeat the analysis at an appropriate dilution for any specimen with an absorbance greater than that of the high concentration calibrator Calculation 1. Perform a best-fit regression analysis of the calibrator concentrations versus the respective absorbance peak area to define the calibration curve. If the results among duplicates vary by more than 10%, sample contamination during processing is likely to have occurred. Hydrocarbons are found alone or incombination with others in a wide variety of commercial products ubiquitous around the home or work place. Lighter fluid, paint thinners, &removers, some furniture polishes, cleaning agents, solvents, various automotive products & 58 Toxicology ordinary fuels are common examples.
