Turnover rates of the neurotransmitters were measured anxiety fear duloxetine 40mg, and their metabolites were altered; there was a significant increase in turnover between serotonin and dopamine anxiety attack symptoms quiz cheap 60mg duloxetine amex, and a decrease in turnover with norepinephrine (Martinez et al anxiety jealousy buy generic duloxetine online. Rats orally exposed to anxiety symptoms upon waking up discount 40 mg duloxetine with amex 5 mg/kg/day of glyphosate or glyphosate-based formulation perinatally from day 9 gestation to day 22 post-natal were found to have increased expression of synaptophysin a marker of synaptic terminals in the hippocampus of both groups (Dechartres et al. Maternal behavior was also observed; at day 1 post-natal, dams were observed to spend less time licking and grooming offspring whereas between day 2 and 6 post-natal, more time was spent with offspring. In vitro studies have also examined glyphosate and glyphosate-based herbicides for neurotoxicity. Glyphosate and an herbicide containing glyphosate isopropylamine as its active ingredient were tested in vitro at concentrations of 0. Although no effect was observed for pure glyphosate, glyphosate-based herbicides were reported to interfere with myelination and also as a demyelinating agent in a dose-dependent manner (Szepanowski et al. However, after testing for demyelination using glyphosate and isopropylamine additively (rather than as formulated), the authors note that this effect may be due to undisclosed additives. Neither glyphosate (pure) nor glyphosate-based herbicide were found to impair neurite development (Szepanowski et al. This study also reported an association with improved fecundability when the women were not involved in pesticide activities; see Table 2-5 for additional information. Although time to pregnancy varied widely by region, no significant associations were found with level of glyphosate usage. In another study, Camacho and Mejia (2017) evaluated the association between aerial applications of glyphosate in Colombia and miscarriages by women living in the sprayed areas. For each additional square kilometer increase in area sprayed with glyphosate there was an increase in the number of miscarriage diagnoses. However, the authors note the way miscarriage was defined in the study may overestimate the number of actual miscarriages. In the study, miscarriage was defined when a mother was observed to have attended a prenatal care visit, but a corresponding birth registry was not located after 10 months. Male F1 offspring of C57B1/6 mice exposed to 420 mg/kg/day Roundup in utero through the end of lactation showed an estimated 5% decrease in epithelial height and a 70% reduction of sperm in the cauda epididymis (Teleken et al. Male Kumming mice exposed to 60, 180, or 540 mg/kg/day Roundup showed no reproductive effects at the lowest dose, but had significantly decreased sperm motility and increased sperm abnormality at the higher two doses (Jiang et al. Two low dose studies using glyphosate and glyphosate-based herbicides with exposures ranging from 1. However, male albino rats orally exposed to Roundup for 12 weeks showed testicular degeneration and increased sperm abnormalities in doses as low as 3. While most studies on male rodents showed reproductive effects, reproductive effects in female rodents exposed to glyphosate or glyphosate formations were not observed consistently. In female rats exposed to 126 mg/kg/day of a glyphosate-based herbicide for 60 days, relative ovary weight decreased by 38% compared to controls (Hamdaoui 2018). In pregnant rats acutely exposed, ovaries were lighter, implanted sites decreased by 42%, total number of corpus luteum were reduced, and pre-implantation loss increased following exposure to 500 mg/kg/day (Almeida et al. However, no reproductive effects were reported in pregnant female C57B1/6 mice orally exposed to 420 mg/kg/day (Teleken et al. In multi-generational studies on female rodents, reproductive effects varied by generation. Results found that the percentage of sperm motility in Roundup-treated samples upon one hour of incubation was significantly lower than in controls; after three hours of incubation, the percentage of sperm motility in Roundup-treated samples was also significantly lower than in controls. Consequently, findings suggest glyphosate disrupts the development and maturation of oocytes by generating oxidative stress and inducing early apoptosis (Zhang et al. During the first 24 hours of treatment, glyphosate at concentrations ranging from 10 ppm to an agricultural dilution 1000 times greater did not impact cell viability, while glyphosate-based formulations resulted in dose-dependent cell death. Glyphosate–based formulations also inhibited glutathione-S-transferase activity, but glyphosate alone did not. Additionally, glyphosate-based formulations induced accumulation of intracellular lipids. Both glyphosate and glyphosate-based formulations resulted in mitochondrial dysfunction signified by reduced Succinate dehydrogenase activity. The authors concluded that herbicide-induced mitochondrial function alterations are formulation-dependent. Glyphogan formulants at sub-agricultural doses were able to rapidly penetrate and accumulate in cells. Given that only one study examined each endpoint and the lack of quantification of glyphosate exposure across studies, these results were not considered sufficient for drawing conclusions on the risk of developmental toxicity associated with glyphosate exposure in humans. No associations were found between paternal exposure and risk of miscarriages (Savitz et al. Similarly, no associations were found between maternal glyphosate exposure and birth weight (Sathyanarayana et al. This dose level resulted in maternal toxicity, thus the developmental effects noted may be secondary to the maternal effects. Increased incidence of kidney tubular dilation was reported for F3b male weanlings in a 3-generation study of glyphosate technical (98. No developmental effects were seen in rat pups exposed to 2 mg/kg/day every 48 hours on post-natal day 1 to 7 (Guerrero Schimpf et al. However, on a per litter basis, there was no statistically significant difference between controls and glyphosate-treated groups. Offspring in the F1 generation showed delays in puberty in males and decreases in weaning weights of both sexes. More serious effects were observed in the F2 and/or F3 generations: significant increases in testis disease, prostate disease, kidney disease, ovary disease, obesity, tumors and parturition abnormalities. Almost a third of F2 generation females (7/20) died during late gestation or experienced litter mortality, whereas neither of these abnormalities were observed in the 16 controls. Male offspring were assessed for reproductive effects after sacrifice at 5 days, 20 days, 35 days, or 8 months old. Significant decreases in sperm counts were observed in males prenatally exposed to both formulations of glyphosate: 0. Exposure to glyphosate technical was associated with decreased serum testosterone and altered testes morphology in rats sacrificed at 20 days old. Developmental endpoints were evaluated in three open-literature studies that employed oral exposure to glyphosate formulations. An additional study on C57B1/6 mice also documented developmental effects on the reproductive system when male F1 offspring exposed to 420 mg/kg/day Roundup in utero through the end of lactation showed increased age at testes descent (Teleken et al. Multi-generational rat studies using intermediate oral exposure to glyphosate-based herbicides found developmental effects of varying severity. Increased anogenital distance was also observed in offspring of F0 dams exposed to glyphosate technical, but, unlike Roundup Bioflow exposure, glyphosate exposure was only associated with this effect in male offspring (Manservisi et al. F1 females from the higher exposure group gave birth to offspring that showed increased fetal anomalies (conjoined fetuses and abnormal limbs) compared to controls, as well as the fetal growth effects found in the lower exposure group (Milesi et al. In a study on rats exposed from gestation day 0 to post-natal day 21, exposure to a glyphosate formulation was associated with impaired neurological development. In male offspring, impaired memory was only seen at higher doses of 200 mg/kg/day. At 100 mg/kg/day, striatum acetylcholinesterase activity was inhibited by 23%, in addition to other effects seen in females at the same dose (Gallegos et al. Serum triglyceride levels increased in gestational day 19 fetuses and postnatal day 21 female offspring and total cholesterol was elevated in postnatal day 7 (males) and 21 (female) offspring. Histological examination revealed clustering of monocytes, indicative of inflammation, in postnatal day 7 females and hepatic lipid droplets in hepatocytes of the offspring mice, with effects more pronounced in males (Ren et al. Overall, offspring mice exhibited hepatic steatosis and excessive lipid droplets formation within hepatocytes suggesting glyphosate alters lipid metabolism (Ren et al. From 2014 to 2016, several meta-analyses were conducted for lymphohematopoietic cancers. The primary literature used in these meta-analyses is discussed later in this section. Schinasi and Leon (2014) conducted a systematic review and meta-analysis of 21 pesticide active ingredients and chemical groups including glyphosate. The Working Group reanalyzed the data, but used the most fully adjusted risk estimates for the studies by Hardell et al. Epidemiological Studies A number of case-control and prospective cohort epidemiology studies have examined possible associations between use of glyphosate-containing compounds and increased cancer risks. Detailed overviews—including a description of the exposure metric used, the results, and the conclusions and limitations as reported by the study authors—are presented in Table 2-7 for solid tumor types and Table 2-8 for lymphohematopoietic cancers. The majority of the studies examined individuals who were occupationally exposed to pesticides and used self-reported or proxy-reported (ever/never use of glyphosate-containing compounds) use as the marker of exposure.

The primary indication for an intestinal approach is the revision of prior penile-inversion vaginoplasties anxiety symptoms gagging buy duloxetine pills in toronto. Since the secretion is digestive there is a risk of malodor and frequent secretions anxiety klonopin buy genuine duloxetine, and secretions are constant rather than only with arousal anxiety symptoms extensive list discount 20 mg duloxetine free shipping. Bacterial overgrowth (diversion colitis) is common and may present with a greenish discharge anxiety symptoms definition 60 mg duloxetine overnight delivery, treatment includes. These usually occur at the midline within 5 cm of the vaginal opening, and are almost universally the result of a surgical injury to the rectum. Small fistulas may only pass flatus, while larger fistulas can allow stool to drain through the vagina. Dilation should continue to avoid closure of the vagina, with the plan to repair the fistula in a minimum of 6 months. The majority of cases do not need or require immediate intervention, and in most cases the patient will still be continent. The patient should be counseled that they will be more susceptible to urinary tract infections-particularly after intercourse. Voiding promptly after intercourse and/or acidifying the urine with juices or cranberry pills is usually adequate preventive care. Fistulas between the bladder and vagina are the least common, but are the most difficult to manage. A foley June 17, 2016 145 Guidelines for the Primary and Gender-Affirming Care of Transgender and Gender Nonbinary People catheter in the bladder will divert a majority, but not all of the urine; in general surgical intervention will be required. Granulation tissue Granulation tissue in the vagina is the result of delayed healing and is common. The need for frequent dilation in the early post-operative period exacerbates the problem by causing repeated trauma to the area of granulation. In most cases this will heal as the need for frequent dilations diminishes over time. If persistent, regular silver nitrate treatments and topical treatment of steroid cream (triamcinolone) or medical grade honey (Medihoney) will speed the healing. Silver nitrate can be applied to granulation areas until cautery is observed with resultant grey scabbing and coagulation. A patient who has recurrent urinary tract infections should be evaluated for a urethral stricture. A simple diagnostic test is to attempt to pass a 16F catheter into the bladder to rule out strictures, including post-bulbar or meatal stenosis. Patients with a mucosal flap causing a large meatus will require meticulous hygiene and possibly prophylaxis. Most patients will see a reduction in their ability to hold larger volumes of urine over longer times as a consequence of the involution of the prostate. Sensation and orgasm No major sensory nerves should have been divided during surgery, so sensitivity should not be adversely affected after vaginoplasty. In an outcome study published in 2002, 86% of the author’s patients were orgasmic. The combination of prolonged estrogen/anti-androgen therapy and orchiectomy during surgery may result in a reported decline in libido for some patients, which is discussed elsewhere in these guidelines.

In a free flap procedure, tissue is completely removed from the donor site along with its blood supply. The blood supply is then anastomosed to a recipient blood supply at the site of transfer. Using either procedure, the donor skin is rolled into a tube like structure and grafted to the inguinal area. In order to minimize the risk of fistula, most commonly this procedure is performed after a hysterectomy and vaginectomy (or vaginal mucosal ablation) is performed. A urethral hookup may be performed using cheek or vaginal mucosa, and an erectile implant may be placed. Often the entire phalloplasty procedure involves multiple staged surgeries, with earlier stages allowing skin grafts to develop local blood supply prior to cosmetic procedures to complete the phalloplasty. Depending on the surgical approach, the penis may or may not have intact erotic sensation. Risks associated with phalloplasty There are general risks associated with any surgery, including infection, bleeding, damage to surrounding tissues, and pain. Specific to phalloplasty in transgender men, there is risk of flap loss, urethral complications, wound breakdown, pelvic bleeding or pain, bladder or rectal injury, lack of sensation, prolonged need for drainage, or need for further procedures. Donor site risks include unsightly scarring, wound breakdown, granulation tissue formation, decreased mobility, hematoma, pain and decreased sensation. If patients are discharged from their surgeon’s care and are not local, they should see their primary care provider every three months during the first year. Different surgeons may also have different complications rates; understanding what procedures different surgeons perform, their experience, frequency with which they perform these procedures, and complication rates is helpful. June 17, 2016 147 Guidelines for the Primary and Gender-Affirming Care of Transgender and Gender Nonbinary People Immediate/early (within one month) complications after free or pedicled flap phalloplasty Wound infections typically occur within the first few weeks after surgery and can present as cellulitis, fungal infection or both. Wound breakdown is common and typically occurs at points where multiple suture lines meet. Most wound breakdown issues can be managed with local wound care (wet to dry dressing changes) as the wounds heal by secondary intention. Some wound breakdowns may require debridement(s), and fewer may require skin grafting or further surgical procedure(s) to close the wound. This is managed by making sure there are no kinks or twists in the tubing, flushing the catheter, and antispasmodic medications (anticholinergics). Flap loss is rare and typically occurs due to technical error (misplaced microsurgical suture or vascular pedicle kinking/compression). Flap loss typically presents within the first 72 hours, and if recognized early (within hours) can be salvaged by emergent return to the operating room. Hypercoagulable states can predispose a patient to clotting after surgery and flap loss. Pelvic or groin hematomas can occur, and may be managed by drains, or may require surgical drainage. While medical deep vein thrombosis prophylaxis with unfractionated heparin or lovenox may place the patient at higher risk of hematoma formation, this risk must be weighed against the risk of deep vein thrombosis and pulmonary emboli. Risk assessment models exist to help determine individualized perioperative anticoagulation modalities. The vaginectomy portion of the procedure involves developing a plane between the posterior wall of the vagina and the anterior wall of the rectum. Inadvertent injury to the rectal wall can present acutely (immediately known and repaired) or subacutely (days to June 17, 2016 148 Guidelines for the Primary and Gender-Affirming Care of Transgender and Gender Nonbinary People weeks later). Recognition of a rectal injury in the subacute period can be based on constitutional symptoms of fever, chills, malaise, or more overt symptoms of sepsis. The portion of the rectum in the surgical field is extraperitoneal, so abdominal pain or peritoneal signs would be unusual. Drainage of stool from the perineal incisions, scrotum or base of the phallus indicates formation of a fistula between the rectal wall and the skin. Such wounds require hospitalization and general surgical involvement in the care plan. A short-term colostomy may be required to divert the fecal stream and allow the fistula to close. Washout of a pelvic abscess and closure of the rectal fistula, with secondary wound healing may be required. Long-term complications after free or pedicled flap phalloplasty Urethral strictures typically present 6-12 months after surgery with symptoms of a weak stream, straining with urination, and sometimes concomitant fistulas secondary to distal obstruction from the stricture. Wound contraction and scarring are complications that occur any time the skin is cut, but the degree to which they occur is highly variable between patients.

It is based on ethical principles and bound by codes, both explicit and implicit, regarding the relationship between physicians and their patients, their profession, and society at large. The key ethical principles that provide the basis of ethical codes, and may be invoked in the resolution of ethical dilemmas include: autonomy, justice, beneficence, and non-malfeasance, among others. For an adolescent patient, provide the necessary anticipatory guidance to maintain optimal sexual health and to help the adolescent avoid behaviors that place them at risk for having negative consequences for their sexual behavior and expression. Since most adolescents require absolute privacy to talk candidly about their sexuality, ask partners, friends, or parents to leave the interview room before taking a history. Assure the patient of complete confidentiality in order to establish trust and respect between yourself and the adolescent patient. Assure the patient of complete confidentiality if the patient is a gay, lesbian, or bisexual adolescent in order to establish trust and respect between yourself and the adolescent patient. Assure gay, lesbian, or bisexual adolescents or adults that you will not inadvertently "out" them to parents or peers. Before providing assurances about confidentiality, explain provincial and institutional boundaries surrounding this issue, especially concerning the treatment of adolescents without parental consent. Respect the diversity and difference inherent in adolescents, including gender, race/ethnicity, sexual orientation, and physical appearance.

Objectives 2 Through efficient, focused, data gathering: ­ Identify the presenting features of the infection: rash, sore throat or diarrhea. Certain communicable diseases/infectious diseases require statutory reporting to the Public Officer of Health. It is important to become informed about the diseases that require reporting in your province. Significant disability has been reported in the quality of life of patients with chronic urticaria. In some instances, it may be disfiguring if it involves the face and lips, or life threatening if airway obstruction occurs from laryngeal edema or tongue swelling. Other (mastocytosis, urticaria pigmentosa) Key Objectives 2 Determine whether the condition is acute, chronic, or a manifestation of a systemic illness based on lesion resolution, length of recurrence, and clinical picture. Objectives 2 Through efficient, focused, data gathering: ­ Elicit a detailed history and physical examination including timing of symptom onset, duration of lesions, identification of precipitants (easier in acute urticaria because onset is<30 minutes and duration is limited). Outline the process involving cutaneous mast cells in the superficial dermis leading to urticaria, and contrast this with the process involving the deeper dermis and subcutaneous tissues leading to angioedema. Affected patients complain of difficulty in initiating and maintaining sleep, and this inability to obtain adequate quantity and quality of sleep results in impaired daytime functioning. Stimulant and other medication (theophylline, steroids, fi-agonists, thyroxine, amiodarone) 2. Objectives 2 Through efficient, focused, data gathering: ­ Conduct an examination of the patient to detect concomitant medical conditions which can adversely affect sleep. It is also encountered at the other extreme of life, the very young, for the same reason: an inability to respond to thirst by drinking water. Insensible loss (unconscious or diminished capacity patients) Key Objectives 2 Since hypernatremia is seldom caused by sodium gain, consider water loss first. Objectives 2 Through efficient, focused, data gathering: ­ Determine the underlying cause of water loss and/or diminished thirst. In children with sodium depletion, the cause of the hyponatremia is usually iatrogenic. The presence of hyponatremia may predict serious neurologic complications or be relatively benign. Identification of the main process is important because it will affect choice of therapy and rate of correction. Objectives 2 Through efficient, focused, data gathering: ­ Determine whether an increase in water relative to sodium exists thereby expanding volume of cells or the change in sodium concentration is artifactual or caused by hyperglycemia. When serum sodium concentration is measured by flame photometry or other methods requiring major dilution of plasma, hyperlipidemia or hyperproteinemia may cause pseudo-hyponatremia (iso-osmotic). Explain how serum sodium concentration represents the major determinant of extracellular osmolarity and how its level of 135 145 mmol/L is controlled. Contrast the mechanism of water retention when water intake is great enough to overwhelm the excretory capacity of the kidney to water retention caused by impaired renal water excretion. Sore throat may be due to a variety of bacterial and viral pathogens (as well as other causes in more unusual circumstances). Infection is transmitted from person to person and arises from direct contact with infected saliva or nasal secretions. Rhinorrhea alone is not infective and may be seasonal (hay fever or allergic rhinitis) or chronic (vaso-motor rhinitis). Such patients usually have a viral upper respiratory infection and do not require diagnostic tests or treatment. Objectives 2 Through efficient, focused, data gathering: ­ Determine whether further testing for group A streptococci is indicated (or other investigation). Sore throat is one of the commonest conditions found by physicians in office practice and emergency departments. Although the major treatable pathogen is group A streptococcus, this organism is the cause of the sore throat in<10% of adults who present with this complaint. Unfortunately, the majority of patients continue to receive presumptive antibiotic therapy for this complaint.

Preoperative radiation therapy with photons and/or electrons Radiation therapy with photons and/or electrons is medically necessary when delivered prior to resection or attempted resection of a soft tissue sarcoma of an extremity, the trunk, or a head and neck site. At the time of surgery, clips should be placed to both identify the periphery of the surgical field and also to identify any potential sites of microscopic or gross residual disease that may be in need of higher amounts of radiation. The medically necessary preoperative dose is 50 Gy using conventional fractionation of 1. Indications and doses medically necessary for a boost due to positive margins are the following: 1. For microscopic residual disease (R1 resection) 3 Gy to 4 Gy given twice daily for a total of 14 Gy to 16 Gy b. For gross residual disease (R2 resection) 3 Gy to 4 Gy given twice daily for a total of 18 Gy to 24 Gy Page 224 of 272 4. Postoperative radiation therapy with photons and/or electrons (all radiation treatments planned to be given during and/or after resection) C. Radiation therapy is medically necessary when delivered at the time of or subsequent to resection or attempted resection of a soft tissue sarcoma of an extremity, the trunk, or a head and neck site. At the time of surgery, clips should be placed to both identify the periphery of the surgical field and also to identify any potential sites of microscopic or gross residual disease that may be in need of higher amounts of radiation, if anything other than an R0 (negative margins) was anticipated. Indications and doses medically necessary for postoperative radiation therapy are the following: 1. External beam radiation therapy with photons and/or electrons 50 Gy using conventional fractionation of 1. For positive surgical margins 16 Gy to 20 Gy followed by 50 Gy external beam radiation therapy using photons and/or electrons with conventional fractionation of 1. For positive surgical margins 3 Gy to 4 Gy given twice daily for a total of 14 Gy to 16 Gy followed by 50 Gy external beam radiation therapy using photons and/or electrons using conventional fractionation of 1. Preoperative radiation therapy with photons With the exception of desmoid tumors, radiation therapy with photons is medically necessary when delivered prior to resection or attempted resection of a soft tissue sarcoma of a retroperitoneal or intra-abdominal location. At the time of subsequent surgery, clips should be placed to both identify the periphery of the surgical field and any potential sites of microscopic or gross residual disease that may be in need of higher amounts of radiation. The preoperative dose is 50 Gy using conventional fractionation with photons of 1. A preoperative dose-painting technique with photons is medically necessary to deliver the following: a. Postoperative radiation therapy with photons Radiation therapy with photons is medically necessary when delivered subsequent to resection or attempted resection of a soft tissue sarcoma of a retroperitoneal or intra-abdominal location. At the time of surgery, clips should be placed to both identify the periphery of the surgical field and to help define potential sites of microscopic or gross residual disease that may benefit from additional radiation. Page 226 of 272 Indications and doses medically necessary for postoperative radiation therapy with photons are the following: 1. External beam radiation therapy with photons of 50 Gy using conventional fractionation of 1. Treatment of primary or metastatic sites for salvage or palliation Palliation of recurrent or metastatic sites of soft tissue sarcoma may be medically necessary when other alternatives are less appropriate. The use of radiation in such circumstances must balance between expedience, the need and ability to relieve symptoms, the high doses that are required to achieve a response, and the potential normal tissue damage that can be inflicted. Palliative treatment with electrons is done with Complex Radiation Therapy technique and should not exceed 15 fractions. Complex Complex technique with photons and/or electrons is medically necessary most commonly in the palliative setting in which a simple, expeditious approach is required to relieve symptoms. This is commonly the situation in cases of curative intent where the clinical circumstance requires doses in excess of 50 Gy. As the radioisotope decays fully, the radiation dose is delivered; the material becomes non-radioactive and can be left in place. Key Clinical Points Radiation therapy with photons and/or electrons is medically necessary in all potentially curable cases of soft tissue sarcoma of the extremity, trunk, head and neck, retroperitoneal and intra-abdominal sites, with the exceptions of retroperitoneal or intraabdominal desmoid tumors, and of low grade, stage I sarcomas that have been resected and oncologically appropriate margins have been achieved. Radiation therapy with photons and/or electrons is medically necessary in palliative cases of soft tissue sarcoma of the extremity, trunk, head and neck, retroperitoneal and intraabdominal sites when other simpler methods of palliation are inadequate, ineffective, or not available. Radiation therapy with photons and/or electrons may play a role in the management of desmoid tumors but is generally limited to sites other than retroperitoneal or intraabdominal. Of the rhabdomyosarcomas, management of the pleomorphic variety is similar to that of other soft tissue sarcomas. The non-pleomorphic variety often occurs in the pediatric population, and its management is less well defined. Treatment is to be given in a multidisciplinary environment in which the radiation oncologist is consulted prior to a resection attempt. Medically necessary radiation therapy with photons and/or electrons employs the use of highly sophisticated treatment planning and the use of highly conformal delivery techniques to achieve a suitable therapeutic ratio of target coverage versus protection of normal tissues. However, further resection may not be feasible for medical or technical reasons and this may serve as an indication for additional radiation (boost) in selected cases. Examples include extremely large tumors, high-grade lesions, or the morbidity of further surgery. The risk and feasibility of administering additional radiation must be weighed against that of additional surgery. Means to mitigate radiation to nearby structures, such as tissue displacement using omentum, biologic or synthetic material, may be incorporated into the resection procedure when additional postoperative radiation is contemplated.

This method is more sensitive in detecting signs of severe anemia, and is less reliable in detecting moderate or mild anemia. The inner eyelid, lips, tongue, gums, and the area under the fingernails are examined and the degree of pallor indicates the severity of anemia. Symptoms of anemia may include weakness, tiredness, headaches, and shortness of breath. Test Characteristics Appropriate settings: Routine screening during physical examination Village level settings where drawing blood is not possible, and/or where cultural beliefs against blood drawing exist Space requirements: Well-lighted environment Accuracy: Sensitivity 64% in severe anemia (hemoglobin level below 7. To evaluate conjunctival pallor (degree of paleness and color), gently pull down the lower lid and determine if the membranes of the inner eyelid appear pale (white pink) instead of red (Figure 5). To assess the pallor of the palm of the hand, open the patient’s hands and partially extend the fingers (Figure 8). Suggestions for Improving Test Performance • the conjunctivae, lips, tongue, gums, palms, and area under the fingernails should all be examined. Disadvantages • Method is highly subjective and will vary according to the viewing angle of the observer. Test Characteristics Appropriate settings: Most useful for screening in rural settings Space requirements: Well-lighted environment Amount of blood sample: One drop of capillary blood Preparation/processing time: 5 minutes Sample/test stability: 10 minutes Accuracy: Sensitivity 60% at 10. Obtain a drop of blood by puncturing either the earlobe or fingertip with a sterile lancet (Figure 9). When the blood spot is no longer shiny, hold the filter paper behind the standardized chart so that the blood spot is visible through the hole in the chart (Figures 11 and 12). After the blood is dropped onto the filter paper, the reading must be performed within ten to fifteen minutes because the color of the blood spot on the filter paper will continue to darken as it dries. Find the color on the chart that most closely matches the color of the blood on the filter paper and record the result. Interpretation Some charts provide readings in grams per liter, while others provide Figure 12 readings in ranges of hemoglobin that indicate normal (>12. If a result indicates moderate to severe anemia, follow up with a more accurate test where possible. Suggestions for Improving Test Performance • Use only the filter paper provided with the chart. Other papers, such as newsprint paper, will give inaccurate readings because they are not calibrated with the chart. Advantages • Inexpensive • Rapid • Simple • No reagents required 15 Chapter 3 Common Anemia Detection Tests • Portable • Electricity not required • Filter paper and color chart are durable if properly maintained and stored Disadvantages • the chart is supplied with a limited quantity of filter paper. Test Characteristics Appropriate settings: Screening programs, such as for blood donors or antenatal clinics Space requirements: Well-lighted environment; flat surface Amount of blood sample: One drop of capillary blood Preparation/processing time: 20 minutes if stock solution must be prepared; 10 minutes if only the standard solutions are prepared from the stock Sample/test stability: 10-15 seconds Accuracy: Sensitivity 87. Store the stock solution in an amber bottle and label it as “Stock Copper Sulfate Solution” with the date of its preparation. To determine the hemoglobin range with more precision, a set of standard solutions can be prepared representing additional hemoglobin values (see chart on next page). Preparation of additional standard solutions for semi-quantitative assessment of hemoglobin Volume of Hemoglobin Level (g/dl) Stock Solution (ml) Volume of Water (ml) Specific Gravity 6. Release a small drop of whole blood from 1 cm above the standard solution (Figure 13). If the blood drop sinks immediately, its hemoglobin value is greater than that of the hemoglobin gram equivalent of the copper Figure 13 sulfate solution. If the blood drop floats for 10 to 15 seconds, the hemoglobin value is equal to or less than the hemoglobin gram equivalent of the copper sulfate solution. After each blood-drop test, mark the label on the bottle to record the number of uses (Figure 14). Using a range of copper sulfate solutions representing additional hemoglobin levels will allow a more accurate assessment of the hemoglobin value. After 50 blood drops have been introduced, the level of accuracy of the reagent decreases and fresh solution must be prepared. Disadvantages • It is often difficult to obtain analytical-grade copper sulfate chemicals in rural areas. It is important to centrifuge the tubes within 6 hours after the blood sample is taken. If you are filling the capillary tube from anticoagulated blood collected by venipuncture, be sure to mix the blood in the anticoagulated tube well first. Record the patient identification with the number of the slot where each tube is placed in the centrifuge. Figure 18 22 Chapter 3 Common Anemia Detection Tests Interpretation If using the reference chart: • Line up the bottom of the red cells at the zero mark (Point A, Figure 19). Disadvantages • Either anticoagulated blood or capillary tubes containing anticoagulant must be used. Principle the Lovibond visual color comparison method is based on comparing the depth of color that results when an accurate measurement of blood is added to a diluting fluid with a set of colored glass standards. The color of the test solution is visually compared with a set of glass standards set in a disc that match the diluted hemoglobin fluid. The intensity of color in the test solution corresponds to a specific hemoglobin level. Test Procedures Prepare either dilute ammonia or Modified Drabkin’s diluting fluid Preparing the dilute ammonia 1. Ideally, it should be handled under a fume hood or with use of a respirator mask where available. Place parafilm or foil wrapper over the Lovibond-type tube and invert the tube gently a few times to mix the blood and the diluting fluid (Figure 22). Place the tube containing the blood and test solution in the Test slot (Figure 23). Light is absorbed simultaneously by both a defined layer of blood (sample) in a glass cell chamber and an empty glass cell standard. The hemoglobin level is obtained by reading the position of the pointer on the scale when the colors of the two cells match. Clean the glass chamber immediately after use with cold, soapy water then rinse thoroughly with clean water. Insert the assembled clip and glass standard into the blood chamber compartment on the side of the photometer (Figure 26). Visually evaluate the calibrating standard through the viewer and adjust the grey wedge until the two visual fields match (Figure 27). Calibrating the Grey Wedge Photometer It is a good practice to check the calibration of the grey wedge when the lamp or batteries are replaced or when results do not match the glass calibrating standard. While the base is immobilized, loosen the two exposed screws and move the adjustable indicator the correct distance (plus or minus) as noted in step one. The chamber must be completely dry before adding the blood, as residual water will dilute the sample and influence the reading. Allow the blood to freely flow onto the lower piece of glass of the chamber (Figure 28). Hemolyze the blood sample on the glass surface by agitating slightly with a Saponin-treated stick. Be sure the blood is fully lysed so that Figure 28 the hemoglobin is fully released from the red blood cells and that the glass chamber has an even, well-lysed sample of blood. The percent of normal can be converted to grams of hemoglobin using a conversion chart.
