The vesicles are caused by separation of the basal layer from the basement membrane with neutrophils and eosinophils. Acrodermatitis Enteropathica this is an autosomal recessive vesiculobullous disease due to a zinc de? The lesions are weeping, crusted erythematous patches affecting the diaper region, perioral, acral, and intertriginous areas (Figure 21. It may present in the neonatal period with diarrhea, anooral dermatitis, and alopecia. Affected infants have a defect in zinc binding protein in the gastrointestinal tract with resultant zinc malabsorption. Breast milk is protective because it contains a zinc binding ligand that facilitates zinc absorption. Acquired forms of this disease occur in infants receiving hyperalimentation with a low or absent zinc content and in malabsorption states (cystic? Incontinentia Pigmenti Incontinentia pigmenti is an X-linked dominant trait and is lethal in males. Ichthyosis the most severe form of ichthyosis occurs as the harlequin fetus, which is inherited as an autosomal recessive characteristic and is present at birth (Figure 21. The hands may appear moist and weeping with no apparent skin covering, and the nails may be A B 21. This infant developed thick plate-like scales and ectro pion immediately after birth followed by respiratory failure and death. The collodion baby (lamellar ichthyosis) is encased in a thick cellophane-likemembranewithanincidenceof1/300,000births. The skin is rough and scaly, and the lesion is most prominent on the extensor surfaces, especially elbows and knees. X-linked ichthyosis is characterized by generalized large, dark scales with sparing of the palms and soles. In one-third, the lesions are present at birth; the incidence is 1/6,000 male births. Prenatal diagnosis by fetoscopic skin biopsy in all forms of ichthyosis is possible. Menkes kinky hair syndrome is X-linked due to a defect in intestinal copper absorption resulting in a low serum copper level and low ceruloplasmin. These lesions last 3 or 4 days and usually disappear with no sequelae, but in malnourished or compromised infants secondary infection may cause serious illness. Skinbiopsyrevealshyperkeratosis,acanthosis,andintracornealvesicleswith small collections of neutrophils, eosinophils, and keratinous debris. Acropustulosis of Infancy Infantile acropustulosis may be present in the neonatal period. It is charac terized by crops of very pruritic, recurrent vesiculopustules ranging from 1 to 3 mm in diameter. Microscopically, there is focal intraepidermal necrolysis followed by the for mation of vesicles that become? Candida Infection Candida colonizes the gastrointestinal tract and skin shortly after birth and may produce both localized (thrush and diaper dermatitis) and disseminated cutaneousinfectionaswellassystemicinfectioninthenewborn(Figure21. Recurrent and persistent infection in infancy may be associated with the use of antibiotics. Syphilis the skin lesions of congenital syphilis are the result of an intrauterine syphilitic infection (Figure 21. In macerated stillborn fetuses, spirochetes can be detected, andthereishepatosplenomegaly,nucleatedredbloodcellsinvillouscapillaries, and chorioamnionitis. Herpes Simplex this infection results from inoculation from genital herpes inthemother. A skin rash occurs in 70%, and 90% of those infants develop systemic disease with lung, liver, gastroin A testinal, and brain involvement with high mortality. Infantwithascalyeruptionreminiscentofthelesionsofsecondary syphilis may appear on the face, trunk, and extremities. It is a dermatomal cutaneous infection caused by reactivation of varicella-zoster virus in the mother. It is a generalized infection with involvement predominantly of the brain, liver, and spleen as well as the skin. The lesions are woody in consistency and do not pit on pressure; traepidermal vesicle (bottom). Sclerema Neonatorum this lesion appears to be a complication of multisystem fail ure with cooling of the skin and subcutaneous adipose tissue from decreased cutaneous perfusion. It is characterized by a widespread induration of the skin that begins between the third and fourth day after birth. The affected areas are smooth, hard, dry, cold to touch, and whitish or waxy in appearance. The condition is limited almost exclusively ant cells and refractile crystals representing triglycerides are to premature infants. Absent nipples, elbow and hip con tractions, skin thicker across buttocks, patulous everted anus, no gluteal crease. The sagittal suture is 6 cm across, brain shows through dura, cataracts, membrane across nares, mouth, and ears. Scleredema usually appears as a diffuse waxlike hardening of the skin in a severely ill newborn from the second to the fourth day after delivery. The skin appendages appear malformed and irregular and the sebaceous glands are increased in number. There is a predis position to basal cell carcinoma and adnexal tumors arising from the lesion, and therefore removal is indicated. Linear Sebaceous Nevus Syndrome this lesion is associated with visceral malformations, including meningeal hemangiomas, congenital heart disease, urinary tract anomalies, nephrob lastomatosis, hydrocephalus, vitamin D-resistant rickets, colobomas, ocular desmoids, seizures, and mental retardation. Congenital Cutaneous Dystrophy (Rothmund-Thomson Syndrome, Poikiloderma Congenitale) this autosomal recessive disease is characterized by skin lesions and congenital cataracts. Abnormalities of the teeth and dystrophic nails, minor skeletal has a diffuse erythematous rash involving the face, arms, and legs. Focal Dermal Hypoplasia (Goltz Syndrome) In this condition there is thinning of the dermis, hypopigmentation and hy perpigmentation, telangiectasia, focal absence of the skin appendages, and A B 21. This is an X-linked abnormality with a variety of malformations of other parts of the body. Nevi less than 2 cm in greatest dimension are by far more frequent than the giant pigmented nevi, which are noted in fewer than 1/20,000 newborns. The incidence of malignant melanoma arising from a giant pigmented nevus is approximately 6%. An extra chromosome 7 (trisomy 7), reported in malignant melanomas, has been found in congenital pigmented nevi also. Microscopically nevus cells extend deep into the dermis and subcutaneous fat and connective tissue and surround skin appendages, blood, and lymphatic vessels in an in? In addition to the melanocytic component, the congenital nevus may contain blue nevus and neural elements. They may be preceded by a pink macular rash and fever; later, plaques may develop in the dermis. The lesions consist of masses of mast cells located in the upper part of the dermis with the overlying dermis nor mal except for increased melanin in the basal layers. The cells areoftenspindleshaped,andtheiridentitymaynotbeappre ciated without a Giemsa stain to demonstrate the presence of metachromatic granules. When diffuse, they may persist throughout life; the disease may be generalized and the liver, spleen, and bone marrow may become involved. Ectodermal Dysplasia Ectodermal dysplasias are a complex heterogeneous group of congenital, nonprogressive, developmental disorders of struc tures derived from ectoderm i. Thehidroticform(Cloustonectodermaldysplasia),inwhich the sweat glands are not affected, is inherited as an autosomal dominant characteristic (Figure 21.

Precautions include caution to arteria tibialis anterior discount 2.5mg amlodipine prevent injuries when using or disposing of needles or other sharp instruments blood pressure goes up when standing amlodipine 2.5 mg on-line. Protective barriers appropriate for procedures should be used heart attack las vegas proven amlodipine 5mg, including gloves blood pressure 5020 amlodipine 10mg line, goggles, gowns, face shields, and other types of protection. Hands and exposed skin surfaces should be immediately and thoroughly washed after contamination with blood or other body fluids. It consists of a penicillin, usually ampicillin, plus an aminoglycoside such as gentamicin. Monitoring for antibiotic toxicity is important as well as monitoring levels of aminoglycosides and vancomycin. Ensure adequate oxygenation with blood gas monitoring, and initiate O2 therapy or ventilator support if needed. Use volume expanders, 10-20 mL/kg (normal saline, albumin, and blood), and monitor the intake of fluids and output of urine. Measures include treating the underlying disease; fresh-frozen plasma, 10 mL/kg; vitamin K (Chapter 80); platelet infusion; and possible exchange transfusion (Chapter 21). Multiple factors contribute to the increased susceptibility of neonates to infection, including developmental quantitative and qualitative neutrophil defects. Metabolic acidosis may accompany sepsis and is treated with bicarbonate and fluid replacement. Immunotherapy progress continues in the development of various hyperimmune globulins, monoclonal antibodies to the specific pathogens causing neonatal sepsis. They may prove to be significant adjuvants to the routine use of antibiotics for the treatment of sepsis. Flow chart based on American Academy of Pediatrics guidelines with some alterations based on clinical experiences. Neonatal meningitis is often accompanied by ventriculitis, which makes resolution of infection more difficult. There is also a predilection for vasculitis, which may lead to hemorrhage, thrombosis, and infarction. Many unusual organisms, including fungi and anaerobes, have been described in case reports of neonatal meningitis in debilitated and normal neonates. Meningitis must be excluded in any infant being evaluated for sepsis or infection. Signs and symptoms of meningitis generally are similar to those reported for sepsis. A Gram-stained smear can be helpful in making a more rapid definitive diagnosis and identifying the initial classification of the causative agent. Normal values range from 8-32 white blood cells in various studies, some of which may be polymorphonuclear cells. Rapid antigen tests are available for several organisms and should be done on spinal fluid. Ventricular tap, with culture and examination fluid, is indicated in patients not responding to treatment. Optimal antibiotic selection depends on culture and sensitivity testing of causative organisms. Ampicillin and gentamicin are usually started as empiric therapy for suspected sepsis or meningitis. Nafcillin, methicillin, or vancomycin should be substituted for penicillin or ampicillin as initial coverage. Studies have shown no advantage to using intrathecal or intraventricular aminoglycosides. A better choice may be third-generation cephalosporins (eg, cefotaxime or cefuroxime). Currently, most clinicians would use ampicillin plus cefotaxime as initial therapy. External ventricular drainage may be indicated in certain cases complicated by ventriculitis. Treatment should continue until 14 days after cultures are negative or for 21 days, whichever is longer. Head circumference should be measured daily, and transillumination of the head and neurologic examination should be performed frequently. Herpetic disease in the neonate does not fit the pattern of chronic intrauterine infection but is traditionally grouped with the others. Toxoplasma gondii is an intracellular parasitic protozoan capable of causing intrauterine infection. The organism exists in three forms: oocyst, tachyzoite, and tissue cyst (bradyzoites). Ingestion of oocysts is followed by penetration of gastrointestinal mucosa by sporozoites and circulation of tachyzoites, the ovoid unicellular organism characteristic of acute infections. Actual transmission to the fetus is by the transplacental-fetal hematogenous route. In the chronic form of the disease, organisms invade certain body tissues, especially those of the brain, eye, and striated muscle, forming bradyzoites. If symptoms are present, they are generally nonspecific: mononucleosis-like illness with fever, lymphadenopathy, fatigue, malaise, myalgia, fever, skin rash, and splenomegaly. The vast majority of congenital toxoplasmosis cases are a result of acquired maternal primary infection during pregnancy; however, toxoplasmic reactivations can occur in immunosuppressed pregnant women and result in fetal infection. The later in pregnancy that infection is acquired, the more likely is transmission to the fetus (first trimester, 17%; second trimester, 25%; and third trimester, 65% transmission). Infections transmitted earlier in gestation are likely to cause more severe fetal effects (abortion, stillbirth, or severe disease with teratogenesis). Rarely, a parasite may be transmitted via an infected placenta during parturition. However, visual impairment, learning disabilities, or mental impairment becomes apparent in a large percentage of children months to several years later. It may also be transmitted in unpasteurized milk, in raw or undercooked meats (especially pork), and via blood product transfusion (white blood cells). Premature infants have a higher incidence of congenital toxoplasmosis than term infants (25-50% of cases in some series). Congenital toxoplasmosis may be manifested as clinical neonatal disease, disease in the first few months of life, late sequelae or relapsed infection, or subclinical disease. Obstructive hydrocephalus, chorioretinitis, and intracranial calcifications form the classic triad of toxoplasmosis. Toxoplasmosis has been associated with congenital nephrosis, various endocrinopathies (secondary to hypothalamic or pituitary effects), myocarditis, erythroblastosis with hydrops fetalis, and isolated mental retardation. The diagnosis of congenital toxoplasmosis is most often based on clinical suspicion plus serologic tests; however, many hospital-based and commercial laboratories frequently are misinterpreted or inaccurate. The recommendation is that all suspected infections be confirmed in a reference laboratory setting such as the Palo Alto Medical Foundation (telephone: 650 853-4828). Direct isolation of the organism from body fluids or tissues requires inoculating blood, body fluids, or placental tissue into mice or tissue culture and is not readily available. Isolation of the organism from placental tissue correlates strongly with fetal infection. Toxoplasma-specific IgE antibodies are found in almost all women who seroconvert during pregnancy. The most characteristic abnormalities are xanthochromia, mononuclear pleocytosis, and a very high protein level. Long-bone films may show abnormalities, specifically, metaphyseal lucency and irregularity of the line of calcification at the epiphyseal plates without periosteal reaction. Congenital toxoplasmosis is a treatable infection, although at present it is not curable. Therapeutic agents are effective in killing the tachyzoite phase of the parasite but are not capable of eradicating encysted bradyzoites. Treatment of acute maternal toxoplasmosis appears to reduce the risk of fetal wastage and decreases the likelihood of congenital infection. Treatment of symptomatic infants during the first 6 months of life consists of a combination of pyrimethamine, sulfadiazine, and leucovorin calcium supplements. Pyrimethamine (1 mg/kg orally) is administered in 1 or 2 divided doses daily or every other day after an initial loading dose of 2 mg/kg/day for 2 days. After a 6-month regimen, treatment can be continued or modified to include 1-month courses of spiramycin alternating with 1-month courses of pyrimethamine, sulfadiazine, and leucovorin calcium for an additional 6 months.
Sommerfelt K: Long-term outcome for non-handicapped low birth weight infants: is the fog clearing? Cyanosis becomes visible when there is more than 3g of desaturated hemoglobin per deciliter heart attack bar cheap amlodipine online. Therefore heart attack mike d mixshow remix order 2.5mg amlodipine free shipping, the degree of cyanosis will depend on oxygen saturation and hemoglobin concentration arteria meningea buy amlodipine paypal. Cyanosis will be visible with much less degree of hypoxemia in the polycythemic compared with the anemic infant arteria mesenterica safe amlodipine 2.5 mg. If the infant has increased respiratory effort with increased rate, retractions, and nasal flaring, respiratory disease should be high on the list of differential diagnoses. Cyanotic heart disease usually presents without respiratory symptoms but can have effortless tachypnea (rapid respiratory rate without retractions). Transposition of the great vessels can present without a murmur (approximately 60%). Is the cyanosis continuous, intermittent, sudden in onset, or occurring only with feeding or crying? Intermittent cyanosis is more common with neurologic disorders, because these infants may have apneic spells alternating with periods of normal breathing. Continuous cyanosis is usually associated with intrinsic lung disease or heart disease. Cyanosis with feeding may occur with esophageal atresia and severe esophageal reflux. Cyanosis of the upper or lower part of the body only usually signifies serious heart disease. The more common pattern is cyanosis restricted to the lower half of the body, which is seen in patients with patent ductus arteriosus with a left-to-right shunt. Cyanosis restricted to the upper half of the body is seen occasionally in patients with pulmonary hypertension, patent ductus arteriosus, coarctation of the aorta, and D-transposition of the great arteries. An infant of a diabetic mother has increased risk of hypoglycemia, polycythemia, respiratory distress syndrome, and heart disease. Infection, such as that which can occur with premature rupture of membranes, may cause shock and hypotension with resultant cyanosis. Amniotic fluid abnormalities, such as oligohydramnios (associated with hypoplastic lungs) or polyhydramnios (associated with esophageal atresia), may suggest a cause for the cyanosis. Congenital defects (eg, diaphragmatic hernia, hypoplastic lungs, lobar emphysema, cystic adenomatoid malformation, and diaphragm abnormality). Periventricular-intraventricular hemorrhage, meningitis, and primary seizure disorder can cause cyanosis. Neuromuscular disorders such as Werdnig-Hoffmann disease and congenital myotonic dystrophy can cause cyanosis. Respiratory depression secondary to maternal medications (eg, magnesium sulfate and narcotics). Choanal atresia is nasal passage obstruction caused most commonly by a bony abnormality. Other causes are laryngeal web, tracheal stenosis, goiter, and Pierre Robin syndrome. In peripheral cyanosis, the skin is bluish but the oral mucous membranes will be pink. The liver can be enlarged in congestive heart failure and hyperexpansion of the lungs. Check for apnea and periodic breathing, which may be associated with immaturity of the nervous system. Observe the infant for seizures, which can cause cyanosis if the infant is not breathing during seizures. With cyanotic heart disease, the PaO2 most likely will not increase significantly. If the PaO2 rises above 150 mm Hg, cardiac disease can generally be excluded but not always. Failure of PaO2 to rise above 150 mm Hg suggests a cyanotic cardiac malformation, whereas in lung disease the arterial oxygen saturation should improve and go above 150 mm Hg. Draw a simultaneous sample of blood from the right radial artery (preductal) and the descending aorta or the left radial artery (postductal). If there is a difference of >15% (preductal > postductal), then the shunt is significant. It is sometimes easier to place two pulse oximeters on the infant (one preductal-right hand; one postductal-left hand or either foot). To confirm the diagnosis, a spectrophotometric determination should be done by the laboratory. Transillumination of the chest (see p 169) should be done on an emergent basis if pneumothorax is suspected. It can also help diagnose heart disease by evaluating the heart size and pulmonary vascularity. The heart size may be normal or enlarged in hypoglycemia, polycythemia, shock, and sepsis. Increased arterial markings can be seen in truncus arteriosus, single ventricle, and transposition. Increased venous markings can be seen in hypoplastic left heart syndrome and total anomalous pulmonary venous return. It is very helpful in identifying patients with tricuspid atresia; it will show left axis deviation and left ventricular hypertrophy. Echocardiography should be performed immediately if cardiac disease is suspected or if the diagnosis is unclear. Ultrasonography of the head can be performed to rule out periventricular-intraventricular hemorrhage. If a tension pneumothorax is present, rapid needle decompression may be needed (see also p 293). Order stat laboratory tests (eg, blood gas levels, complete blood cell count, and chest x ray film). Treat the infant with methylene blue only if the methemoglobin level is markedly increased and the infant is in cardiopulmonary distress (tachypnea and tachycardia). Administer intravenously 1 mg/kg of a 1% solution of methylene blue in normal saline. It is important to prepare the family in advance, if possible, for the death of an infant and to be ready to answer questions after the event. Early neonatal death describes the death of a live born infant during the first 7 completed days of life. Late neonatal death refers to the death of a live born infant after 7 but before 28 completed days of life. Usually several immediate family members in addition to the parents are present at the hospital. It is good practice to ensure that there is a contact telephone number available for any sick infant. If the family members are not present, telephone contact must be made as soon as possible to alert the family that their infant is dying or has already passed away. The religious needs must be respected and the necessary support provided (eg, priest, rabbi, minister, or pastoral care). Every hospital has pastoral services, and it is useful to inform the minister in advance because some parents may request that their child be baptized before death. It is important to remember that the infant may continue with a gasp reflex for a while even without spontaneous respiration and movement. The heartbeat may be very faint; therefore, auscultation for 2-5 min is advisable. Examination of the infant by the physician to determine death may be done in that same private area, with the family. Much of the equipment (eg, intravenous catheters and endotracheal tubes) may be removed from the infant unless an autopsy is anticipated. In that case, it is best to leave in place central catheters and possibly the endotracheal tube. This type of visual and physical contact is important to begin the grieving process in a healthy manner and try to relieve any future guilt. Parents and immediate family members should be in a quiet, private consultation room, and the physician should calmly explain the cause and inevitability of death.
Knowledge of postharvest physiology is therefore fundamental to pulse pressure physiology order amlodipine online from canada understand the process of deterio ration of quality before reaching the processor arrhythmia jokes order amlodipine american express. Cultivar and rootstock selection influence the composition prehypertension blood pressure diet cheap amlodipine on line, quality heart attack acoustic order discount amlodipine line, storage potential, and response to processing characteristics that may be inherited. In many cases, fruit cultivars grown for fresh market sale are not suited for processing and vice versa. For example, grape varieties used for wine-making are different from those used for fresh food market. Several criteria are used by breeders in the development of new varieties, such as higher yield, resistance to disease and disorders, improved compositional and nutritional values, reduction in undesired toxic compounds, and improved processing characteristics. Out of the pool of several varieties, there have been studies to identify those that suit a particular processing method [12,33,43,61,103,117]. Modern processors usually contract out growers who grow a particular variety or cultivar that suits the raw material specifications for a given type of processing. Recently, there has been a significant amount of work reported on the modification of genetic makeup to improve the postharvest performance of fruits and vegetables [33,108,118]. Transgenic fruits and vegetables have been released that have reduced browning and softening tendencies, and increased shelf life [33], and uniformity of flavor and color. The duration, intensity, and quality of light during cultivation affect the quality at harvest. Exposure to sun tends to make citrus Improved Quality Claims fruits lighter in weight, with thinner rind, low amounts of juice and acids, and high solid content Produce Traits compared to those that were shaded or those inside Apple Reduction in the incidence of bitter pit a canopy. The differences in day length and light Banana Delayed ripening, increased quality affect the product physiology; for example, bruise resistance onion varieties developed for short-day climates Melon Altered ripening will not produce large bulbs [112]. In purple cab Eggplant Seedless bage and eggplants, formation of anthocyanin pig Cucumber Seedless ments is controlled by short wavelengths of light in Pepper Altered ripening and improved flavor Potato Reduced bruise sensitivity, the blue and violet regions [75]. Thiamine synthe increased amylopectin sis in plants is stimulated by light and generally Strawberries Delayed softening and ripening occurs in the leaves and increases in concentration Tomato Increased solid content, delayed ripening, until the plant matures. Turnips harvested in the increased shelf life morning contain more riboflavin than those har vested at other times of the day [85]. Among leafy vegetables, leaves are larger and thinner under a condition of low light intensity [75]. Fruits grown in cold climate usually are more acidic than those grown in warmer regions [100]. Fertilizer addition affects the mineral content of fruits, while other cultural practices such as pruning and thinning may influence nutritional composition by changing fruit crop load and size [49]. Many physiological disorders have been linked to the nutrient status of the soil [86]. Potatoes grown in sandy, gravelly or light loamy soils, and low-water or fertility soils have consistently produced higher dry matter than those grown in peat or low-moisture soils. A high N/K ratio and phos phorus deficiency in soil increases the tendency of potato to darken after cooking. Pineapple plants receiving undue amounts of nitrogen produce tart, white, and opaque fruits of poor flavor characteristics [86]. Pesticide residues may give rise to flavor taints in fresh and processed products, and excessive use of pesticides may even produce harmful metabolites and toxicity that may not be necessarily destroyed during processing or heat treatment [86]. The optimum harvest maturity is vital to achieve maximum postharvest life of the fresh produce [49,52]. Although most fruits reach peak eating quality when harvested fully ripe, they are usually picked mature, but not ripe, to decrease mechanical injury during postharvest handling. Immature fruits are more subject to shriveling and mechanical damage, and are of inferior quality when ripened. Overripe fruits are likely to become soft and mealy with insipid flavor soon after harvest. Fruits picked either too early or too late in the season are more sus ceptible to physiological disorders and have a shorter storage life than those picked at mid-season [49]. Harvesting fruits either immature or overripe can cause extensive loss of the produce; thus maturity indices are important criteria used for arriving at a correct harvesting stage. The optimum maturity of produce for fresh consumption and processing is determined by the purpose for which it will be used. The maturity stage considered best for canning may not be best for dehydration, freezing, or making jams or preserves. For example, fully ripened fruits should be used for drying and making concentrated products (tomato sauce) to achieve the best flavor, but for fresh marketing these may not be suitable for its susceptibility to damage. Maturity indices vary among types, cultivars of the produce, and intended processing. The indices used are based on (i) measurable change in visual appearance (size and shape, overall color, skin color, flesh color, presence of dried outer mature leaves, drying of plant body, devel opment of abscission layer, surface morphology and structure, and fullness of fruit); (ii) elapsed days from full bloom to harvest, and mean heat units during development; (iii) physical changes (ease of separation or abscission, flesh firmness, tenderness, specific gravity or density); (iv) chemical changes (soluble solids, starch, acidity, sugar/acid ratio, juice content, oil content, tannin content); and (v) meas urable physiological changes (respiration and internal ethylene concentration).

Winery Technology and Operations, Wine Appreciation Guild, San Francisco, 1996; A. Each method has its own limitations and advantages and accurate assessment can only be done using a combination of indices [49,56,86]. The advantages of manual harvesting are (i) accurate selection and grading according to maturity, (ii) minimum damage to commodity, (iii) minimum capital investment, and (iv) mechanical devices can be used as aids to manual harvesting. The advantages of mechanical harvesting are (i) it is fast and (ii) it requires low labor and easy management. The disadvantages are (i) it may cause mechani cal damage to the produce by skin abrasion and tissue bruising and (ii) it requires trained personnel and a special field lay out, and cropping patterns. The use of improper machinery and equipment in mechanical harvesting may cause serious food losses [86]. The harvesting system used and its management has a direct effect on incidence and severity of mechanical injuries. Thus, for best results, management procedures should include the following: (i) selection of optimum time to harvest regarding fruit maturity and climatic 24 Handbook of Food Preservation, Second Edition conditions, (ii) training and supervision of workers, and (iii) effective quality control procedure [46]. Pickers can be trained in methods of identifying the produce that is ready for harvest [56]. Harvested vegetables other than root crops should not be placed directly on the soil or be exposed to sunlight, heat, and rain. Exposure to sun can lead to a high internal temperature, which is detrimental to the quality [82]. A simple shade or grass coverage can provide protection to the harvested products. Some root crops can benefit by brief exposure to the sun to dry off the surface or facilitate removal of adher ing soil [86]. Picking during the day or nighttime, and weather conditions also affect the quality. Harvesting during or immediately after rains should be avoided and preferably carried out during the cooler part of the day (usually early morning) to avoid shriveling and wilting. Since most of the water is free water, the produce will continue to lose water to the surrounding atmosphere. The loss in water manifests into symptoms of shriveling, wilting, and loss of crispness. The reduction of saleable weight and loss of sensory characteristics lower the marketing value. The surface area/volume ratio, nature of surface, presence/absence of cuticle, number of stomata (leaves) and lenticels (fruits), periderm (tubers and roots), and injury to the plant tissues affect both the rate and the extent of water loss. This is the reason why leafy vegetables such as lettuce lose water at higher rates than potatoes and apples. Provided exposures to temperatures leading to chill ing and freezing injuries are avoided, lowering temperature during handling, transportation, and storage is the most effective means of extending the shelf life and reducing the loss of quality by lowering the metabolic processes such as respiration and transpiration. The difference in the effect of temperature on the shelf life varies due to differences in physicochemical properties of different types of fruits and vegetables.
