Once completed, this maneuver results in a total release of the muscle from its surrounding fascia. The loose fibrofatty tissue of the supraclavicular fossa and the absence of well-defined dissection planes within this area make knife dissection ineffective here. Some anatomical landmarks define the boundaries of the surgical field in the posterior triangle. The posterior margin is clearly marked by the anterior edge of the trapezius muscle, and the upper boundary is defined by the exit of the spinal accessory nerve toward the trapezius muscle. The transverse cervical vessels and the omohyoid muscle constitute important anatomical landmarks within this area. The sternocleidomastoid muscle is retracted anteriorly, and the external jugular vein is divided and ligated low in the neck if this was not done at a previous stage of the operation. The dissection then proceeds from the anterior border of the trapezius muscle in a medial direction including the lymphatic contents of the supraclavicular fossa. The upper margin of this area presents the greatest risk of damage to the spinal accessory nerve. Displacement of the nerve is due to its connections with the second, third, and fourth cervical nerves. During the dissection of this region several supraclavicular branches of the cervical plexus may be found. They follow a similar course but are located superficial to the spinal accessory nerve. Although the difference between the eleventh nerve and the supraclavicular branches is easily noticed, the novice surgeon may sometimes find this to be difficult. Figure 4-37 the spinal accessory nerve crossing the posterior triangle of the neck on the right side. Note the supraclavicular branch of the cervical plexus following a similar but more superficial course. The omohyoid muscle is then identified, and its fascia is dissected off the muscle to be removed with the contents of the posterior triangle. The muscle may be transected at this moment if this will be required for the removal of the primary tumor; otherwise it is preserved and retracted inferiorly with a smooth blade retractor. Usually they are easily dissected free from the surrounding fibrofatty tissue, displaced inferiorly, and preserved. However, the numerous variations in the branches and the exact manner of branching of the thyrocervical trunk restrain the systematization of this step. The deep layer of the cervical fascia over the levator scapulae and scalene muscles is now visible. The brachial plexus is easily identified as it appears between the anterior and middle scalene. Staying superficial to the scalene fascia prevents injuring the brachial plexus and the phrenic nerve. The dissection is continued medially until it reaches the level of the anterior border of the sternocleidomastoid muscle. The muscle is then pulled laterally with retractors and the contents of the supraclavicular fossa are passed underneath to meet the tissue previously dissected from the upper half of the neck. The sternocleidomastoid muscle is then retracted posteriorly, and the dissection continues anterior to the muscle toward the carotid sheath. A small bridge of tissue still separates these two blocks and connects the specimen to the deep cervical muscles. Figure 4-40 Anterior view of the anatomic landmarks on the right supraclavicular fossa. Using a scalpel, this bridge is transected and the fascia of the levator scapulae muscle is identified. This maneuver creates a single block that must be dissected free from the deep muscles toward the carotid sheath. As the dissection proceeds medially, several branches of the cervical plexus are found. A thorough knowledge of neck anatomy is essential to combine oncological radicalism with functional surgery.

National Nutrition Council adults Viet Nam General recommendation Have milk and dairy products properly for each age. Cow milk does not contain appreciable amounts of iron and presents a high renal solute load to infants compared with breast milk, owing to its higher contents of minerals and protein. The factors that lead to greater adult attained height, or its consequences, increase the risk of cancers of the colorectum and breast (postmenopause), and probably increase the risk of cancers of the pancreas, breast (premenopause) and ovary. Dietary fat from milk is important in the diets of infants and young children and especially in populations with a very low fat intake. Dietary dairy and bone health Milk contains calcium and protein, important for bone health, and some dairy products also provide other nutrients that support bone health, such as potassium, zinc, vitamin a, and, if fortified, vitamin D. Calcium requirements vary depending on dietary factors such as intake of vitamin D, animal source proteins and sodium and other factors such as physical activity and sun exposure. However, milk consumption during adult life does not appear to be associated with reduced risk of fracture. Milk avoidance is possibly associated with increased risk of fracture in children. Milk consumption in childhood may protect against the risk of osteoporotic fractures in postmenopausal women. For older people in countries with high fracture risk, there is convincing evidence for a reduction in risk of osteoporotic fracture with sufficient intake of vitamin D and calcium together (especially in people who have very low intakes of calcium, vitamin D or both). There may be a protective effect of milk and dairy on weight due to components such as protein. Dairy is a dense energy source and energy balance is critical to maintaining healthy body weight. Cross-sectional epidemiological studies indicate that high dairy food intake can contribute to weight management, but prospective studies and randomized controlled intervention trials have yielded inconsistent results. Whether dairy consumption in childhood has an etiologic role in the development of obesity in later life is an open area of discussion. Some studies suggest that dairy food consumption may have a beneficial impact on some MetS components. Cancer Some components in milk and dairy products such as calcium, vitamin D (fortified milk), sphingolipids, butyric acid and milk proteins may be protective against cancer. Diets high in calcium and high consumption of milk and dairy may be a cause of prostate cancer.

These guidelines are not intended to be overly prescriptive, for example, they do not provide chemotherapeutic dosage recommendations. However, these guidelines do place special emphasis on three topics of paramount importance in oncology case management: safety in handling chemotherapeutic agents, delivery of radiation therapy, and relationships with the owners of cancer patients. As in all aspects of clinical veterinary medicine, each member of the healthcare team represents the practice as a whole. An underlying theme of these guidelines is that all staff members, including clinical and administrative personnel, can positively influence the outcome of an oncology case. A unified healthcare team that speaks with one voice will actively support a long-term relationship with a client who entrusts the practice with the care of a pet diagnosed with cancer. Cytology provides information based on the microscopic appearance of individual cells. Fine-needle sampling, which may or may not involve aspiration, can be performed safely for the majority of external tumors, without sedation or anesthesia. When performing fine-needle sampling, aspiration is useful when the tissue is firm and may be of mesenchymal origin, but collecting samples without aspiration can often result in more diagnostic samples and lead to less blood contamination for soft tissue masses of round cell origin. Internal tumors can be sampled with ultrasound guidance depending on location, ultrasound appearance, and size. Cytology can often provide a definitive diagnosis of round cell tumors, and can be helpful in categorizing other tumors as mesenchymal or epithelial. With training and experience, the general practitioner can often determine the presence and type of neoplasia in the office. Submission to a clinical pathologist for diagnostic confirmation is usually indicated prior to therapy. Cytology does not provide tumor grade information and may not always provide a clear-cut diagnostic result due to poor sampling technique or the tumor type. The goal of histopathology is to provide a definitive diagnosis when unobtainable by cytology. Histopathology provides information on tissue structure, architectural relationships, and tumor grade-results that are not possible with cytology. The histologic tumor grade may guide the choice of treatment and provide prognostic information. Proper technique is critical when performing a surgical biopsy, particularly to obtain an adequate diagnostic sample and to prevent seeding of the cancer in adjacent normal tissues. Basic biopsy principles include the following: the primary care clinician, specialist, and pet owner must work together as a unified healthcare team and have a shared understanding of the options, procedures, and expectations of referral treatment. These include when the primary care veterinarian or the client wishes to consider all possible treatment options or when the referring veterinarian cannot provide optimum treatment for any reason. In addition, specialty referral practices often have access to clinical trials in which the client may want to participate. Referrals are appropriate when the primary care clinician can no longer meet the needs and expectations of the patient and client. The comfort level of the primary clinician and client with referral treatment will dictate how early in the process case transfer should occur. The importance of a clear, shared understanding of the referral process by the pet owner, primary care veterinarian, and specific referral specialists or referral centers cannot be overemphasized. Determination of the preferred method of collaboration and case transfer between the primary care clinician and specialist should be made in advance of the referral treatment. After referral, it is important to establish a treatment plan for ongoing communication and continuity of care between the primary care clinician, the specialist, and the owner. Place samples in an adequate amount of formalin (10 parts formalin to 1 part tissue). To avoid seeding adjacent normal tissue with cancer cells, place the biopsy incision so that it can easily be excised at the time of definitive tumor removal. Diagnosis of Tumor Type Once the possibility of a neoplastic process is suspected, determination of the tumor type serves as the basis for all subsequent steps in patient management. Table 1 lists common tumors diagnosed in dogs and Table 2 lists the most common tumors diagnosed in cats. A biopsy is the basic tool that allows removal and examination of cells from the body to determine the presence, cause, or extent of a disease process. Nodal metastasis seen more commonly and earlier than systemic (liver, bone, pelvis, lung). Often slowly progressive unless diffusely metastatic at diagnosis or compromised renal function due to hypercalcemia.

The work of these organizations reflects some collaboration but their activities have been siloed to a large degree. It has generally proposed an ever-growing list of process-oriented measures (or measures of short-term outcomes), which frequently are reported from administrative claims databases or patient sampling and are, therefore, relatively inexpensive to produce (Pronovost and Lilford, 2011). The long-term strategy should focus on the needs of all individuals diagnosed with or at risk for developing cancer. The committee believes that clinicians, through their professional organizations, should be the primary actors because having clinicians guide the process will help ensure that the resulting reporting program is acceptable to practicing clinicians and reflects of key quality issues in cancer care. Moreover, these organizations are already in the process of developing quality metrics for their members. In the past, these organizations have collaborated on an ad hoc basis but more systematic collaboration would speed progress toward this goal. A key component of developing a formal long-term strategy for quality measures for cancer will be prioritizing, funding, and directing the development of meaningful quality measures, with a focus on outcome measures, and with performance targets for use in publicly reporting the performance of institutions, practices, and individual clinicians. These measures should target gaps in cross-cutting, non-technical measures as well as measures for specific types of cancers that have largely been excluded from previous efforts to develop new measures. While data availability will be an important consideration, it should not be the sole factor in measure selection. A formal tool could be developed to assist with prioritizing and selecting measures for development. Achieving this recommendation will likely require the development of a learning health care system for cancer care, as discussed in Chapter 6. These data could then be aggregated to assess individual and organizational performance, and made publicly available to inform patients and other decision makers. The committee recognizes that implementation of this recommendation will present significant challenges. Preventive Services Task Force, which establishes recommendations on cancer screening and prevention. The manual for generating these guidelines is updated regularly to reflect significant changes in methodology standards. It has produced recommendations on screening for breast, bladder, cervical, colorectal, lung, oral, ovarian, pancreatic, prostate, skin, testicular, and thyroid cancer, as well as some recommendations on cancer prevention. The standards are stringent, resource intensive, and require significant investments in time and human resources. A rating of the level of confidence in (certainty regarding) the evidence underpinning the recommendation. A description and explanation of any differences of opinion regarding the recommendation. Reasonable notice of impending publication should be provided to interested public stakeholders. As discussed above, quality metrics provide insights into which aspects of health care require improvement and may be used to assess the success of performance improvement initiatives. They can also be used by individual clinicians to assess their performance and improve the care they provide (Blayney et al. To be successful, health care organizations must foster a culture of change through a variety of activities, such as those discussed in this report. Performance improvement initiatives, which are conducted at the local level, have been described as "systematic, data-guided activities designed to bring about immediate, positive change in the delivery of health care in a particular setting," as well as across settings (Baily, 2006, p. These activities are interrelated and overlapping with quality improvement and patient safety initiatives. Because these efforts are implemented in a single organization or health system, they can be undertaken immediately without action on a national or system level and can be tailored to the unique circumstances of the local environment. Experts have noted, however, that traditional approaches to performance improvement-physician practice peer review, public reporting of quality measures, continuous performance improvement and total quality management, and regulatory and legislatively imposed reforms and penalties-lack the pace, breadth, magnitude, coordination, and sustainability to transform health care delivery (Chassin and Loeb, 2011; Davies, 2001). Leadership is needed to create an institutional culture that values high quality care, a key component of successful performance improvement initiatives.

There is enlargement of the occipital horns as part of the malformation, not due to obstructive hydrocephalus. Sonographic appearance of callosal agenesis: correlation with radiologic and pathologic findings. Furthermore, there is no evidence of intra-spinal extension, a finding that, while not always present, would favor neuroblastoma. Although teratomas can be predominantly cystic, the presence of fatty and/or calcific densities, which are not seen here, would more strongly favor the diagnosis of teratoma. While round pneumonias can occur in the perihilar region, the lesion in this case is centered in the mediastinum rather than the parenchyma of the lung. Also, the attenuation would be expected to be higher in a case of round pneumonia. Cardiomegaly is typically severe in patients with Ebstein anomaly, and pulmonary vascularity is usually more diminished. Further, a right aortic arch is not typically seen in patients with Ebstein anomaly B: Incorrect. A common cause of unilateral air-trapping in this age group is aspirated foreign-body, which may have an indolent presentation. Once diagnosed, these are removed bronchoscopically to prevent complications such as chronic bronchiectasis. However, the findings in the kidneys of the test case are not those of cystic renal dysplasia which presents normal size kidneys which are hyperechoic with scattered macroscopic cysts of varying size; instead, they are classic of autosomal recessive polycystic kidney disease, which is not associated with posterior urethral valves. Ultrasound would demonstrate a mass in the head of the pancreas, without the classic whirlpool abnormality seen on the test case. Duodenal duplication presents as a simple or complex cyst with bowel signature, medial to the duodenum. Neuroblastoma Hepatoblastoma Cirrhosis Liver abscesses Key: A Findings: A small left adrenal mass with calcifications is seen on the non-contrasted scan. Hepatoblastoma may be a consideration but would not explain the calcified adrenal mass in this previously healthy patient. Cirrhosis in infancy is almost always associated with history of chronic liver disease such as biliary atresia, chronic hepatitis or underlying metabolic disorders. Key: A Congenital high airway obstruction syndrome Thanatophoric dysplasia Surfactant deficiency disease Total anomalous pulmonary venous connection Findings: the lungs are enlarged with flattened or inverted hemidiaphragms. Pulmonary or pleuropulmonary blastoma is an extremely rare malignant tumor in children that can be cystic or solid. However, lesions are typically multicystic, and the diagnosis is so uncommon that it would not be the most likely choice. In utero, this results in lung fluid trapped in the obstructed lobe, with overdistension and mass effect including mediastinal shift. Digital detectors can capture the exposure variations linearly (with a gradient = 1) over the full dynamic range, and depend upon subsequent image processing to render the radiographic contrast appropriately for the diagnostic task. Most, if not all digital detectors have poorer spatial resolution than the corresponding screen-film detector. However, there are situations related to infrequent exposure where 5 mSv is allowed, such as exposure to a patient administered a radionuclide and cannot be released from the hospital. What is the average annual natural background radiation level in the United States? Portable radiographs taken with a film-screen system utilizing a fixed radiographic grid tend to have less contrast than radiographs taken in radiography rooms because of which of the following? Use of lower kVp Use of higher mAs Use of lower grid ratio radiographic grid Use of higher speed film-screen system Key: C Rationale: A: Incorrect. Reduce mAs Reduce kVp Reduce pitch Reduce gantry rotation time Key: C Rationale: A: Incorrect. The product of the tube current and exposure time, referred to as the mAs, determines the number of x-rays produced during the scan.

Because retirement pensions for public safety workers with sufficient years of service often involve sharp changes in benefit eligibility and retirement incentives at specific ages, controlling for age is particularly important when studying these occupations. Finally, the aims of the current study emphasize gender to a greater degree than has been the case in earlier studies of injured workers in California. Statistical Methods Our main results use a differences-in-differences specification using weighted least squares regression to contrast the change in total labor earnings from the two years before the date of injury with the two years following the injury between workers with cancer claims and workers with medical-only injuries. We used linear regression and related statistical models to estimate the impact of cancer claims on earnings and employment. All workers with cancer reported as the nature of injury were excluded from the medical-only control group even if they did not receive indemnity benefits. These controls are particularly important in the present study because retirement can generate sharp reductions in employment for public safety workers at the same ages when cancer is likely to be detected. We also include controls for industry and number of workers at the employer at injury. We include similar controls for seven categories of employer size at the time of injury, which is particularly important in the more heterogeneous other occupations group. The central assumption of our differences-in-differences approach is that if the workers with cancer claims had not developed cancer, their earnings would have continued to evolve in parallel with the control group of workers with medical-only injuries. We indirectly tested this assumption by estimating unweighted (ordinary least squares) event-study regression models to capture the differential change in quarterly earnings in each calendar quarter from two years before injury through two years after injury. We found some evidence that this assumption was not valid for some occupations; that is, that the average worker with a medical-only injury was on a slightly different trajectory from the average worker with a cancer claim over the two years leading up to injury. We then reweighted the control group using these probabilities to reflect the characteristics in the cancer claim group, upweighting individuals who were likely to have made a claim (based on observed characteristics), and downweighting individuals who were unlikely to have made a cancer claim. This approach minimizes the divergence in preinjury earnings trajectories between workers with cancer and workers with medical-only claims and is similar in spirit to inverse propensity weights. Poisson regression is more robust than linear regression to outliers and thus is a useful model for studying labor earnings. These specifications may be particularly relevant for estimation of gender differences in earnings losses: female workers with cancer claims have lower earnings than male workers, and so we were concerned that comparing earnings losses between genders in dollar terms could be misleading. We use the Poisson regression estimates when we describe earnings losses in percentage terms. Methods for Calculating Pretax Wage Replacement Rates Estimating wage replacement rates for this study posed some additional challenges. Disability and death benefits are intended to compensate workers and their families for losses caused by injury, including long-term earnings losses. Yet no timely study can directly observe long-term outcomes for injured workers, and so analysts seeking to describe replacement rates face unavoidable trade-offs in choosing the time period after injury over which to calculate wage replacement rates: the longer the time period considered in estimating wage replacement rates, the stronger the assumptions needed to justify the estimates. For most of the workers in our sample, we did not have long-term follow-up data with which to estimate earnings losses beyond two years after injury. Marginal income tax rates increase with income, and so this approach will tend to understate wage replacement rates by a greater margin for higher-income workers. Because of differences across occupations in earnings dynamics and coverage by cancer presumptions, all estimates are presented separately by occupation for the four occupation groups defined in Chapter 2: peace officers, firefighters, lifeguards, and other occupations. Peace officers, firefighters, and workers in other occupations all experience sharp reductions in earnings in the years following a cancer claim. Employment rates for these groups of workers are reported in the second panel of the table. Compared with workers in other occupations, public safety workers have very high employment rates two years prior to injury. Two years after injury, employment has dropped substantially for public safety workers, from nearly 100 percent to 83 percent for peace officers and 84 percent for firefighters. Declines in employment for lifeguards are more muted, with 92 percent employed two years after injury. Workers in other occupations are very likely to stop working in the two years following a cancer claim: only 37 percent are employed two years after the date of injury. While this group also has less stable employment than public safety workers prior to injury (with Table 3.

When symptoms do occur, they may include fever, runny nose, and painful lesions (fever blisters or cold sores) on the lips or in the mouth. Cold sores are spread by direct contact with the lesions or saliva of an infected person. Only exclude a child with open blisters or mouth sores if the child is a biter, drools uncontrollably, or mouths toys that other children may in turn put in their mouths. Usual symptoms can include sore throat, runny nose and watering eyes, sneezing, chills, and a general achiness. Colds may be spread when a well person breathes in germs that an infected person has coughed, sneezed, or breathed into the air or when a well person comes in direct contact with secretions from the nose, mouth, or throat of an infected person. Make sure the childcare facility is well ventilated, either by opening windows or doors or by using a ventilation system to periodically exchange the air inside the childcare facility. Teach children to cover coughs in the elbows and wipe noses using disposable tissues in a way that secretions are contained by the tissues and do not get on their hands. Such exclusion is of little benefit since viruses are likely to be spread even before symptoms have appeared. Cryptosporidiosis is a common cause of diarrhea in children, especially those in childcare settings. Symptoms usually include watery diarrhea and cramping, but can also include nausea and vomiting, general ill feeling, and fever. Healthy people who contract cryptosporidiosis almost always get better without any specific treatment. While this parasite can be spread in several different ways, water (drinking water and recreational water) is the most common method of transmission. Cryptosporidiosis outbreaks in childcare settings are most common during late summer/early fall but may occur at any time. The usual disinfectants, including most commonly used bleach solutions, have little effect on the Cryptosporidium parasite. An application of a 3% concentration of hydrogen peroxide seems to be the best choice for disinfection during an outbreak of cryptosporidiosis in the childcare setting. If an outbreak of cryptosporidiosis occurs in the childcare setting: Contact the Division of Public Health, Office of Infectious Disease Epidemiology at 1-888-295-5156. Health officials may require negative stool cultures from the infected child before allowing return to the childcare setting. Exclude any child or adult with diarrhea until the diarrhea has ceased or as directed by the Division of Public Health. Wash your hands after using the toilet, after helping a child use the toilet, after diapering a child and before preparing or serving food. Note: In larger facilities, when staffing permits, people who change diapers should not prepare or serve food. Disinfect toys, bathrooms, and food preparation surfaces daily or when visibly soiled. Make sure children wear clothing over their diapers to reduce the opportunity for diarrheal leakage. Occasionally, older children in childcare develop an illness similar to mononucleosis, with a fever, sore throat, enlarged liver, and general ill feeling. Thus, it may be spread through intimate contact such as in diaper changing, kissing, feeding, bathing, and other activities where a healthy person is exposed to the urine or saliva of an infected person. Childcare providers who are, or may become pregnant should be carefully counseled about the potential risks to a developing fetus due to exposure to cytomegalovirus.

Often the facial nerve cannot be evaluated acutely because patients are uncooperative, unconscious, or sedated. In an uncooperative patient, one method of stimulating facial movement is to induce pain. This can be accomplished by a sternal rub, or by placing a Q-tip or instrument in the nose and stimulating the septum. Longitudinal injuries classically result from a blow to the temporal parietal region. This image illustrates the long axis of the temporal bone and the course of longitudinal (red dashed line) and transverse (blue-dashed line) patterns of fractures. It houses the otic capsule, internal audiotry canal, petrous carotid, and portions of the facial nerve and forms the petrous apex. This includes the full-body trauma assessment, particularly of the airway, breathing, circulation, and neurological status, as well as the remainder of the body assessment. During the secondary survey, the cervical spine should be evaluated and cleared if possible. Particularly pertinent to temporal bone injuries, the head and neck examination will obviously assess any otologic damage, to include facial nerve function, hearing deficits, bedside vestibular function testing, neurological status, and in particular facial nerve function and otoscopic examination. Otoscopic examination may reveal a step-off in the canal where the fracture is, blebs and ecchymosis, or a perforation. A patient with a normal-hearing ear will indicate the signal from air conduction is greater than bone conduction (termed a positive Rinne). The audiogram should be repeated prior to ossiculoplasty or tympanoplasty surgery to determine residual hearing loss. The otic capsule is very dense, and fractures involving the otic capsule are 148 resident Manual of trauma to the Face, head, and Neck uncommon. Neurologic injuries include concussion and injuries to the brainstem and vestibular/cerebellar pathways, and may co-exist with inner ear injuries. The evaluation of a patient with dizziness should include a detailed neurologic evaluation and a bedside vestibular evaluation. Further testing with audiogram and vestibular function tests is useful, but are usually obtained when the patient can be tested in the office setting with appropriate equipment In trauma patients, a cervical spine injury should be ruled out before performing the vestibular evaluation. A fracture of the otic capsule generally results in a severe vestibular injury, but injuries can occur in the absence of a fracture. This complex anatomy and narrow bony pathway make the facial nerve highly susceptible to injury in temporal bone fractures. Aberrant regeneration occurs and can leave patients with some weakness and synkinesis. Temporal bone fractures involve the intratemporal nerve rather than the peripheral branches, producing generalized hemifacial weakness. Marked edema limits facial expression and can give the impression of reduced facial movement. Furthermore, highly expressive movement on the normal side will cause some passive movement on the paralyzed side near the midline. A patient with paralysis may appear to have limited function that is actually passive movement resulting from the uninvolved side. When 150 resident Manual of trauma to the Face, head, and Neck this is suspected, the examiner should physically restrict movement on normal side by pressing on the facial soft tissue and reassess for any movement on the injured side. Sometimes terms like complete paralysis (indicating no movement) and incomplete paralysis (meaning weakness or paresis) are used. Although temporal fractures produce hemifacial involvement, it is best to record function for all five distal regions (forehead, eye closure, midface, mouth, and neck), as there may be some variation in the degree of dysfunction. A partial facial nerve injury can progress to a complete paralysis over the course of a few days. Patients who present with a paresis rather than a paralysis, who later progress to a complete paralysis, generally have a good prognosis for spontaneous recovery. These patients typically have much more severe facial nerve injuries and are more likely to benefit from facial nerve exploration and repair. This is why early clinical evaluation to establish baseline facial nerve function is so important.

Twenty-nine evaluations and studies were identified and rated based on quality of design and level of inference, in ascending order: observational/formative (5); adequacy (10); plausibility (8); and probability (6). The chapter describes the typical model, evidence for impact, and lessons learned for four programme types: dairy production and agriculture programmes; school-based milk programmes; fortified milk programmes; and milk powder and blended foods. Dairy production programmes were found to be more effective than traditional agriculture production interventions if strategies included: targeting inputs to women; the introduction of small livestock; and communication about the nutritional value of milk. School-based programmes improved body composition and micronutrient status, but issues of appropriate levels of fat, added sugar and flavouring in milk need to be addressed. Evidence for positive nutrition outcomes was strongest from fortified milk programming, though issues of limited market access, cost, and questionable effects on zinc nutrition remain. Finally, milk has been added to blended foods for decades but the effect of the milk ingredient is largely unknown. To conclude, dairy programming faces many challenges including the need for higher-quality evaluations that assess cost-effectiveness and consideration of the dual burden of under- and overnutrition. The findings demonstrate that milk and dairy programmes can simultaneously improve nutrition and reduce poverty, aided by the generally positive public perception of milk. With planning and investment, milk may contribute to improving the health and well-being of many globally. Deficiencies in some micronutrients, including vitamin A, iodine, iron and zinc, contribute significantly to global burden of disease (Black et al. Iodine deficiency, the leading cause of mental retarda- 276 Milk and dairy products in human nutrition tion globally, affects 36. The condition may arise from multiple causes, several of which are related to dietary deficiencies in iron, vitamin A and B12, folate, riboflavin and copper, and can lead to impairment of cognitive and physical development in young children, poor birth outcomes in pregnant women and, in severe cases, increased risk of mortality in certain populations (Hoffbrand, Moss and Pettit, 2006). Poor diets and high infection burden are the primary causes of micronutrient deficiencies in developing countries. Milk is an excellent source of both macro- and micronutrients, as discussed in Chapters 3 and 4. Milk also contains nutrients critical for growth and development, including calcium, vitamin A, riboflavin and vitamin B12 (Hoppe et al. In some countries, both under- and overnutrition are prevalent in the population and even within the same household. There is some evidence linking food-supplementation programmes in Latin America with weight gain above the reference median (Uauy, Albala and Kain, 2001). However, milk programming has not been implicated in increasing obesity, though an awareness of the problem is needed moving forward. The association between dairy intake and weight gain and obesity is examined in detail in Chapter 4. There is widespread consensus and strong evidence now showing that undernutrition during the first two years of life is a strong predictor of child mortality (Black et al. Interventions targeting infants and young children are widely recognized to be the most effective in terms of increasing child survival and improving growth (Bhutta et al. This chapter focuses on milk programmes affecting undernutrition, as the major challenge in developing countries for young children in particular. A review of the literature is presented covering four major programme types: dairy production and agriculture programmes; school-based milk programmes; fortified-milk programmes; and milk powder and blended foods. Under each programme type, there is a brief description of the typical programme model, followed by an overview of the evidence-base linking the milk-related interventions to nutrition. Most of the programmes reviewed in three of the categories (dairy production and agriculture programmes, fortified-milk programmes and milk powder and blended foods) targeted children less than five years of age. Databases searched included: Proquest; PubMed Central; Science Direct; and Scopus. In addition, web pages from several international agencies and nongovernmental organizations were searched for grey literature, monographs and evaluations. The following criteria were used to decide whether to include a programme in the study: 1) milk or dairy products were part of the intervention; 2) nutrition, and in some cases health and anthropometry of participants, was affected through the diet; 3) the study was intended to inform programming (observational/formative) or included an evaluation that allowed the possibility of inferring adequacy, plausibility or probability (see following paragraph); and 4) the programme context was a developing country. Programmes were classified into four levels of inference, to indicate quality of design and methods.
