27 Diarrhea: definitionIncreased total daily stool output, usually associated with increased stool water contentStool output more than 10g/kg/24hr or more than the adult limit of 200 g/24hrResults from altered intestinal water and electrolyte transportGIT of infant handles approx 285 ml/kg/24hr of fluid (intake plus intestinal secretion) with a stool output of 5-10g/kg/24hr

36 ETIOLOGYINCUBATION PERIODSIGNS AND SYMPTOMSDURATION OF ILLNESSASSOCIATED FOODSLABORATORY TESTINGTREATMENTCampylobacter jejuni2–5 daysDiarrhea, cramps, fever, and vomiting; diarrhea may be bloody.2–10 daysRaw and undercooked poultry, unpasturized milk, contaminated waterRoutine stool culture; Campylobacter requires special media and incubation at 42°C to grow.Supportive care. For severe cases, antibiotics such as erythromycin and quinolones may be indicated early in the diarrheal disease. Guillain-Barré syndrome can be a sequela.Enterotoxigenic E. coli (ETEC)1–3 daysWatery diarrhea, abdominal cramps, some vomiting3 to >7 daysWater or food contaminated with human fecesStool culture. ETEC requires special laboratory techniques for identification. If suspected, must request specific testing.Supportive care. Antibiotics are rarely needed except in severe cases. Recommended antibiotics include TMP-SMX and quinolones.
37 ETIOLOGYINCUBATION PERIODSIGNS AND SYMPTOMSDURATION OF ILLNESSASSOCIATED FOODSLABORATORY TESTINGTREATMENTEnterohemorrhagic E. coli (EHEC) including E. coli O157 : H7 and other Shiga toxin–producing E. coli (STEC)1–8 daysSevere diarrhea that is often bloody, abdominal pain and vomiting. Usually, little or no fever is present. More common in children <4 yr old.5–10 daysUndercooked beef especially hamburger, unpasteurized milk and juice, raw fruits and vegetables (e.g., sprouts), salami (rarely), and contaminated waterStool culture; E. coli O157 : H7 requires special media to grow. If E. coli O157 : H7 is suspected, specific testing must be requested. Shiga toxin testing may be done using commercial kits; positive isolates should be forwarded to public health laboratories for confirmation and serotyping.Supportive care, monitor renal function, hemoglobin, and platelets closely. E. coli O157 : H7 infection is also associated with hemolytic uremic syndrome (HUS), which can cause lifelong complications. Studies indicate that antibiotics may promote the development of HUS.
38 ETIOLOGY INCUBATION PERIOD SIGNS AND SYMPTOMS DURATION OF ILLNESS ASSOCIATED FOODSLABORATORY TESTINGTREATMENTSalmonella spp.1–3 daysDiarrhea, fever, abdominal cramps, vomiting. S. typhi and S. paratyphi produce typhoid with insidious onset characterized by fever, headache, constipation, malaise, chills, and myalgia; diarrhea is uncommon, and vomiting is not usually severe.4–7 daysContaminated eggs, poultry, unpasteurized milk or juice, cheese, contaminated raw fruits and vegetables (alfalfa sprouts, melons). S. typhi epidemics are often related to fecal contamination of water supplies or street-vended foods.Routine stool culturesSupportive care. Other than for S. typhi and S. paratyphi, antibiotics are not indicated unless there is extra-intestinal spread, or the risk of extra-intestinal spread, of the infection. Consider ampicillin, gentamicin, TMP-SMX, or quinolones if indicated. A vaccine exists for S. typhi.Shigella spp.24–48 hrAbdominal cramps, fever, and diarrhea. Stools may contain blood and mucus.Food or water contaminated with human fecal material. Usually person-to-person spread, fecal-oral transmission. Ready-to-eat foods touched by infected food workers, e.g., raw vegetables, salads, sandwiches.Supportive care. TMP-SMX recommended in the U. S. if organism is susceptible; nalidixic acid or other quinolones may be indicated if organism is resistant, especially in developing countries.

41 CLINICAL IMPRESSIONACUTE INFECTIOUS DIARRHEA WITH MODERATE SIGNS OF DEHYDRATION
43 STOOL EXAMINATION Examine for mucus, blood and leukocytes Fecal leukocytes are indicative of bacterial invasion of colonic mucosaExamine for parasites causing diarrhea such Giardia lamblia and E. histolyticaShouldd be obtained as early in the course of disease as possible from children with bloody diarrhea
44 STOOL CULTUREShould be obtained as early in the course of disease as possible from children with bloody diarrhea in whom stool microscopy indicates fecal leukocytes
48 Oral Rehydration Therapy Children especially infants are more susceptible than adults to dehydration because of the greater basal fluid and electrolyte requirements.Dehydration must be evaluated rapidly and corrected 4-6hrs according to the degree of dehydration.
49 Oral Rehydration Therapy Those in shock or unable to tolerate fluids, require initial intravenous rehydration but oral rehydration is the preferred mode of replacing ongoing losses.
50 Risks associated with severe dehydration that necessitate IV resuscitation Age <6mosPrematurityChronic illnessFever >38C if <3mos or 39C if 3-36mosBloody diarrheaPersistent emesisPoor urine outputSunken eyesDepressed level of consciousness
51 Oral Rehydration Therapy Decarbonated soda beverages, fruit juices are not suitable for rehydration as they have inappropriately high osmolalities and low sodium concentrationsORS should be given to infants and children slowly, especially if they have emesisIt can be given by a dropper, teaspoon or syringe.The volume is increased as tolerated.
52 Enteral Feeding and Diet Selection Continued enteral feeding in diarrhea aids in recovery and age appropriate diet after rehydration is the norm.Once rehydration is complete, food should be reintroduced while oral rehydration can be continued to replace ongoing losses from emesis or stools.
53 Enteral feeding and Diet Selection Breast feeding should be resumed as soon as possibleFoods with complex carbohydrates, yogurt, fruits and vegetables are also toleratedFatty foods or foods high in simple sugars should be avoided.
54 Zinc supplementationZinc leads to reduced duration and sseverity of diarrhea and could potentially prevent 300,000 deaths.WHO and UNICEF recommend that all children with acute diarrhea should recive oral zinc for days during and after diarrhea10mg/day for infants <6mos20mg/day >6mos
55 Antibiotic TherapyTimely antibiotic therapy may reduce the duration and severity of diarrhea and prevent complications.While these agents are important to use in specific cases, their widespread and indiscriminate use leads to development of resistance.

61 N. Pashapour, S. Golmahammadloo Pediatrics Department, Imam Hospital EVALUATION OF YOGHURT EFFECT ON ACUTE DIARRHEA ON 6-24 MONTHS-OLD HOSPITALIZED INFANTSN. Pashapour, S. GolmahammadlooPediatrics Department, Imam HospitalHealth Department, Kosar Hospital, Urmia, Iran The Turkish Journal of Pediatrics 2006; 48:
62 OBJECTIVESTo determine the efficacy of local factory pasteurized yoghurt consumption in acute nonbloody and mucoid diarrhea on hospitalized 6-24 months infants as compared with that of routine treatment
63 SUBJECTS6 to 24 months of age children with non-bloody and mucoid diarrhea with less than four days duration hospitalizing in Urmia; Imam Hospital2 GROUPS (20 EACH)Control group: routine hospital treatment onlyCase group: received at least 15 ml/kg/day of pasteurized cow milk yogurt orally plus routine hospital treatmentWeight gain, period of hospitalization and reduction of diarrhea were compared
65 RESULTS reduction of diarrhea episodes Mean hospitalization days : 2.85 – 3.1Mean weight gain : 350 – 287.5Mean reduction of diarrhea episodes : 4.35 – 3.95Significant difference (P<0.50) reduction of diarrhea episodes
66 CONCLUSIONUse of local pasteurized yoghurt in the treatment of acute diarrhea had positive effectsAs a probiotic, it can promote recovery from diarrhea in children, mainly non-bloodyUniversal use of yoghurt is recommended in acute non-bloody diarrhea
