We present the case of a 31-year-old Peruvian female with severe dehydration due to diarrhea and vomiting. The patient was one of a number of travelers arriving in Los Angeles on an international flight from Argentina and Peru. Because of the travel history and clinical presentation, cholera was suspected and ultimately confirmed by stool culture. The patient's clinical course is outlined, and discussion of the relevant epidemiology and clinical management of cholera is provided. Physicians should suspect cholera when treating patients with severe gastroenteritis. The short incubation period, rapid onset of dehydration and shock, and high case fatality rate of untreated cholera require a consideration of cholera in patients with diarrhea and recent travel to areas where cholera is prevalent.

Cholera is a disease rarely imported in the Netherlands. Recently a 34-year-old woman who had returned from a trip through Thailand was admitted to our hospital with complaints of vomiting, watery stools and moderate dehydration. Vibrio cholerae OI serotype Ogawa biotype El Tor was isolated from the faeces. She recovered after antimicrobial and fluid therapy. Her 29-year-old travelling companion had only mild symptoms of diarrhoea, but the bacterium was isolated from her stool also. Cholera should be considered in travellers with vomiting and diarrhoea coming back from Thailand.

Recombinant A-B+ Vibrio cholerae O1 strain CVD 103-HgR is a safe, highly immunogenic, single-dose live oral vaccine in adults in industrialized countries. Safety, excretion, immunogenicity, vaccine transmissibility, and environmental introduction of CVD 103-HgR were investigated among 24- to 59-month-old children in Jakarta. In 81 households, 1 child was randomly allocated a single dose of vaccine (5 x 10(9) cfu) and another, placebo. Additionally, 139 unpaired children were randomly allocated vaccine or placebo. During 9 days of follow-up, diarrhea or vomiting did not occur more often among vaccines than controls. Vaccine was minimally excreted and was isolated from no controls and from 1 (0.6%) of 177 unvaccinated family contacts. A 4-fold or higher rise in serum vibriocidal antibody was observed in 75% of vaccines (10-fold rise in geometric mean titer over baseline). Of 135 paired placebo recipients or household contacts, 5 had vibriocidal seroconversions. Moore swabs placed in sewers and latrines near 97 households failed to detect vaccine. These observations pave the way for a large-scale field trial of efficacy.

Cholerae is a grave and acute bacterial intestine infection which is caused by a bacilo, V. cholerae 01, that produces toxic products. Its clinical symptoms range from abundant liquid diarrhoea combined with vomiting and rapid dehydration. It is highly lethal when right treatment is not applied. There are also cases of cholera where victims do not show any symptoms of it, that is asymptomatic carriers. Any clinical suspicion of cholerae has to be corroborated by epidemiological data and its diagnostic confirmation should be done by isolating the bacteria, V. cholerae. When beginning the treatment, it is not necessary to confirm the diagnostic and this is based on the restitution of the liquids lost through vomiting and facing using any methods that are recommended for any other type of diarrhoea. The antimicrobial treatment is used only for grave cases. This present revision includes recent knowledge about cholerae emphasising on the effective management of cases through an adequate use of right treatment methods and also using the principal prevention measures against dissemination of this disease.

Clinical profile of cholera was studied in children attending Diarrhea Training and Treatment Unit from January-December 1993. Out of a total 8714 cases of acute watery diarrhea, 64 children (0.7%) were suspected to have cholera on the basis of acute onset loose water/rice watery stools, high purge rate with or without excessive vomiting and/or severe dehydration. Stool culture was positive for cholera in 33 cases (51.6%). All the isolates were V. cholerae 01 biotype El Tor serotype Ogawa. Sixty four per cent of stool culture positive cases were below 5 years of age. The results assume importance because out of 28 children < 2 years with clinical suspicion of cholera, 11 cases (39.3%) were culture positive for V. cholerae, youngest child being 3 months old. Comparison of various parameters revealed that presence of vomiting > 4 episodes/ day (p < 0.005), frequency of stools >12/24 hours (p <0.002), rice watery stools (p < 0.01) and presence of severe dehydration (p < 0.01) were significant parameters associated with positive stool culture. Beside examination of stool sample by hanging drop method was an excellent diagnostic tool (p < 0.001) with a sensitivity of 51.5%, specificity 100% and positive predictive value of 100%. The isolates of V. cholerae were susceptible to furazolidone, cephelexin, nalidixic acid, norfloxacin and gentamicin. Our observations indicate that cholera is not uncommon in infants and young children. Like children in the older age group, acute onset diarrhea with watery/rice watery stools and high purge rate with or without excessive vomiting and/or rapid development of severe dehydration should arouse suspicion of cholera in younger children also. They should be investigated for cholera even in non-endemic areas and in the absence of cholera outbreaks.

Clinical features of infantile diarrhea were studied among 603 infants from birth to 12 months of age to determine the predominant clinical feature(s) seen in infantile diarrhea associated with a specific enteric pathogen. Among the major clinical features, fever was most often seen in diarrhea due to Yersinia spp. (61.5%) followed by that in rotavirus (26.1%). Vomiting was mostly associated with Vibrio cholerae infection (90.9%) and shigellosis (64.6%). Dehydration was predominant in Vibrio cholerae (90.9%) and Salmonella (84.9%) infections. Bloody diarrhea was mostly due to Shigella infection (74.3%). As regards diarrhea with multiple pathogens, vomiting and dehydration were most frequent with Campylobacter+Enteropathogenic Escherichia coli (EPEC) (88.9% and 77.8%, respectively), while fever was more common with rotavirus+Shigella+Escherichia coli and rotavirus+Giardia. Infection with invasive organisms lead to vomiting, 4-10 stools per day and dehydration significantly more often as compared to infections with non-invasive organisms. Similarly more stools of patients infected with invasive organisms showed presence of blood and more than 5 leukocytes/HPF as compared to those infected with non-invasive organisms.

Clinical and epidemiological characteristics of diarrhea associated with Vibrio mimicus were identified in 33 hospitalized patients referred to the Costa Rican National Diagnostic Laboratory Network between 1991 and 1994. The relevant symptoms presented by patients included abundant watery diarrhea, vomiting, and severe dehydration that required intravenous Dhaka solution in 83% of patients but not fever. Seroconversion against V. mimicus was demonstrated in four patients, from whom acute- and convalescent-phase sera were obtained. Those sera did not show cross-reaction when tested against Vibrio cholerae O1 strain VC-12. All the V. mimicus isolates from these cases produced cholera toxin (CT) and were susceptible to commonly used antibiotics. Attempts to isolate this bacterium from stool samples of 127 healthy persons were not successful. Consumption of raw turtle eggs was recalled by 11 of the 19 (58%) individuals interviewed. All but two V. mimicus diarrheal cases were sporadic. These two had a history of a common source of turtle (Lepidochelys olivacea) eggs for consumption, and V. mimicus was isolated from eggs from the same source (a local market). Among the strains, variations in the antimicrobial susceptibility pattern were observed. None of the strains recovered from market turtle eggs nor the four isolates from river water showed CT production. Further efforts to demonstrate the presence of CT-producing V. mimicus strains in turtle eggs were made. Successful results were obtained when nest eggs were tested. In this case, it was possible to isolate CT- and non-CT-producing strains, even from the same egg. For CT detection we used PCR, enzyme-linked immunosorbent assay (ELISA), and Y-1 cell assay, obtaining a 100% correlation between ELISA and PCR results. Primers Col-1 and Col-2, originally described as specific for the V. cholerae O1 ctxA gene, also amplified a 302-bp segment with an identical restriction map from V. mimicus. These results have important implications for epidemiological surveillance in tropical countries where turtle eggs are used for human consumption, serving as potential sources of cholera-like diarrhea.

In a total of 720 faecal specimens from patients with secretory diarrhoea, vomiting, dehydration, gastroenteritis, cholera and cholera like illnesses, 18 strains of V. mimicus were isolated as pure culture. These were characterized for various toxin types and virulence factors using conventional in vitro and in vivo assays. Labile and stable toxins were elaborated by 15 and 2 strains respectively by ligated rabbit ileal loop (RIL) and suckling mouse assays. While 15 of the whole cell culture elaborated labile toxin, only 7 strains produced the same when culture filtrate was tested in RIL assay. Culture filtrates of 15 strains exhibited vascular permeability factor (PF) on adult rabbit skin, none of the strains were invasive as indicated by Sereny's test. Culture supernatants of all strains produced a cytotoxic factor to Vero and Chinese hamster ovary cells. Four of the 18 strains (22%) were resistant to multiple drugs (a combination of 3 or more drugs). The results emphasize the significance of continuous screening and identification of V. mimicus and to include in the differential diagnosis of patients with acute diarrhoea.

While cholera is not endemic in Taiwan, the number of imported cases is increasing. We report a 59-year-old Taiwanese male who developed severe diarrhea and vomiting, two days after returning from Bali. The patient admitted drinking a beverage with ice purchased from a street vendor. On admission he was weak and dehydrated. The patient suffered from hypovolemic shock and acute renal failure. Elevated creatine phosphokinase indicated rhabdomyolysis. Fluid replacement with Ringer's lactate solution was instituted. Dyspnea and pulmonary edema developed, and hemodialysis was begun to remove excess fluid due to decreased urinary output. Isolation of Vibrio cholerae O1 from stool confirmed the diagnosis of cholera, and doxycyline was begun. The patient's condition stabilized, with increased urinary output, and resolution of diarrhea, vomiting and dyspnea. Cholera, although rare in Taiwan, can be lethal if left untreated. Rapid intervention with fluid replacement is essential to prevent hypovolemic shock and circulatory collapse in severe cases.

A retrospective review of cases seen in the Diarrhea Treatment and Training Unit (DTU) of Bangalore (India) Medical College's Vani Vilas Children's Hospital during 1992-1994 confirmed the efficacy of the standard case management approach. This strategy entails oral rehydration therapy (ORT), continued feeding, and selective use of intravenous fluids and antibiotics. Of the 7966 children (4374 males and 3592 females) reporting to the DTU during the 2-year study period, only 2412 (30.5%) had received oral rehydration solution (ORS) or home-available fluids before admission. Acute watery diarrhea was present in 7316 cases (91.84%). Death occurred in 59 acute watery diarrhea cases, 6 dysentery cases, and 7 persistent diarrhea cases. The average time for cases managed in the ORT area was 2 hours and 45 minutes, while the hospital stay for admitted cases averaged 3 days. In 6957 cases (87.33%), ORS was sufficient treatment. Of the 1009 children (12.67%) who required intravenous fluids, 254 had dehydration attributable to conditions such as persistent vomiting and inability to drink due to oral thrush. Only the 512 children (6.2%) with cholera and dysentery received antibiotics. Of the 72 children who died (case fatality rate, 0.9%), 43 had associated severe malnutrition with pneumonia and anemia, 14 had a central nervous system infection, and 13 had septicemia; in only 2 cases could death be directly ascribed to diarrheal disease. One of these cases was due to shigella encephalopathy and the other to severe dehydration with acidosis. The average cost of treatment per patient was Rs 2.91 when only ORS was used compared with Rs 24.28 when intravenous rehydration was required. The finding that less than one-third of children had received ORS before admission suggests a need for the establishment of more DTUs in large hospitals that can train community-based health personnel in diarrhea case management.
