In July 1995 an outbreak of pharyngoconjuctivitis caused by adenoviruses occurred among athletes participating in a swimming contest in a town in southern Greece (Peloponnese). At least 80 persons displayed symptoms of the illness, with the predominant ones being high fever, sore throat, conjuctivitis, headache, and abdominal pain. Poor chlorination was probably the cause of the outbreak (residual chlorine <0.2 mg/l), as after hyperchlorination the spread of adenoviruses stopped. Rapid detection of adenoviruses in the municipal swimming pool water by nested polymerase chain reaction (PCR) amplification allowed quick control of the outbreak.

Alocasia macrorrhiza (L) Schott and Endl is called Hai Yu, Tien Ho, Shan Yu, Kuan Yin Lien, Tu Chiao lien, Lao Hu Yu and Lang Du in Chinese. Its common English name is Giant Elephant's Ear. The toxic effects of A macrorrhiza arise from sapotoxin and include gastroenteritis and paralysis of the nerve centers. From 1985 to 1993 all individuals who called the Poison Control Center asking for information regarding macrorrhiza were included in this retrospective study. A questionnaire filled out by the Poison Control Center staff collected the demographic data of the victim, the reason for consumption, the prescribed part, clinical symptoms and signs of the victim, and medical outcome of poisonings. Among 27 cases of A macrorrhiza poisoning, the age was 1.5 to 68 y with 12 females and 15 males. One had skin contact and 1 had eye contact. In the 25 cases that consumed the plant leaf or tuber either raw or cooked, the primary symptom was in injected sore throat and the secondary symptom was numbness of the oral cavity. Some patients had salivation, dysphonia, abdominal pain, ulcers of the oral cavity, difficulty in swallowing, thoracodynia, chest tightness and swollen lips. We believe the presence of sapotoxin alone is not sufficient to explain the injected swollen and ulcerative lesions. Calcium oxalate is reported distributed in the entire plant and results in inflammation of the oral cavity and mucous membranes just as our patients had.

This retrospective descriptive study aims to characterise and compare the clinical manifestations, course and outcome of 16 Oriental patients with adult-onset Still's disease diagnosed in the last 4 years with published data based on Western populations and another Oriental (Japanese) series. Like the Japanese, we found a female preponderance, an older age at onset, and fewer patients with abdominal pain, myalgia, sore throat and serositis compared to the Western series. A longer delay in diagnosis occurred in patients lacking either arthritis or rash at presentation. Most patients had mild hyponatraemia and 2 patients had overt syndrome of inappropriate anti-diuretic hormone secretion. All patients showed a dissociation of elevated aldolase with normal to low creatine kinase levels. Over 50% relapsed within a year from diagnosis and needed slow-acting anti-rheumatic drugs as steroid-sparing agents. Two were given intravenous pulse cyclophosphamide therapy for progressive pneumonitis. Outcome was generally good with minimal functional impairment and no mortality.

The purpose of this study was to determine the frequency with which general pediatricians perform a rectal examination on children with a complaint of acute abdominal pain and to determine factors associated with performing a rectal examination. Children were eligible for the study if they were 2 to 12 years of age and presented to the clinic or emergency department of a municipal teaching hospital with a complaint of abdominal pain of less than or equal to three days' duration. Measured variables included demographic characteristics and presenting signs and symptoms. For each patient, a clinical reviewer (1) assigned a final diagnosis, (2) determined whether a rectal examination had been performed, and (3) assessed the clinical contribution of the rectal examination findings. For 1,140 children presenting for a nonscheduled visit with acute abdominal pain, a rectal examination was performed on 4.9% (56/1,140). Using multiple logistic regression, children were more likely to have a rectal examination performed if they had abdominal tenderness (odds ratio [OR] = 3.3 and 95% confidence interval [CI], 1.8 to 6.0), a history of constipation (OR = 6.0 and 95% CI, 2.3 to 15.3), or a history of rectal bleeding (OR = 9.1 and 95% CI, 2.9 to 29). Children were less likely to have had a rectal examination performed if they presented with associated symptoms of cough (OR = 0.32 and 95% CI, 0.14 to 0.74), headache (OR = 0.15 and 95% CI, 0.05 to 0.46), or sore throat (OR = 0.28 and 95% CI, 0.08 to 0.91). The final diagnoses of 12 children who had clinically contributory findings on rectal examination included: constipation (5), gastroenteritis (3), appendicitis (2), abdominal adhesions (1), and abdominal pain of unclear etiology (1). General pediatricians infrequently perform a rectal examination on children who present with a complaint of acute abdominal pain. Clinical factors affect the likelihood of whether a rectal examination is performed.

Psittacosis, also referred to as ornithosis, is a disease primarily of birds, which may be transmitted to humans. Psittacosis is caused by Chlamydia psittaci, an obligate intracellular parasite found worldwide. Humans are infected with C. psittaci when the organism enters the blood stream, usually through inhalation of dried excrement from diseased birds or through wound contamination with infected avian secretions. C. psittaci replicates in the liver and spleen and infects the lung and other organs hematogenously.1 The clinical manifestations of human psittacosis range from a mild respiratory infection to a severe systemic illness.1,2 Symptoms are frequently described as flu-like with fever, headache, body aches, and dry or productive cough. Sore throat, chest pain, abdominal pain, vomiting, and diarrhea are variably present. Physical findings may include a pulse-temperature dissociation, localized lung crackles, hepatomegaly, splenomegaly, and a pale macular skin rash. Chest radiographs may demonstrate lesions that are atelectatic, patchy, miliary, nodular, or consolidated in one or both lungs. White cell counts, erythrocyte sedimentation rates, and liver function tests are usually normal. In severe illness, signs and symptoms of liver dysfunction, neurological impairment, and respiratory and renal failure may be present. Since 1879 when psittacosis was recognized as a disease entity, cases have been reported in North and South America, Europe, Asia, and Australia. However, reports of psittacosis in Africa have been rare. An Ethiopian group, studying community-acquired pneumonia, published what they claimed to be the first report of psittacosis in Africa in 1994.3 The report published here is believed to be the first documented case of human psittacosis in Egypt.

During the 1995 outbreak of Ebola hemorrhagic fever in the Democratic Republic of the Congo, a series of 103 cases (one-third of the total number of cases) had clinical symptoms and signs accurately recorded by medical workers, mainly in the setting of the urban hospital in Kikwit. Clinical diagnosis was confirmed retrospectively in cases for which serum samples were available (n = 63, 61% of the cases). The disease began unspecifically with fever, asthenia, diarrhea, headaches, myalgia, arthralgia, vomiting, and abdominal pain. Early inconsistent signs and symptoms included conjunctival injection, sore throat, and rash. Overall, bleeding signs were observed in <45% of the cases. Typically, terminally ill patients presented with obtundation, anuria, shock, tachypnea, and normothermia. Late manifestations, most frequently arthralgia and ocular diseases, occurred in convalescent patients. This series is the most extensive number of cases of Ebola hemorrhagic fever observed during an outbreak.

Venezuelan hemorrhagic fever (VHF) is a severe disease characterised by fever, malaise, sore throat, followed by abdominal pain, diarrhea, a variety of hemorrhagic manifestations and convulsions. The arenavirus Guanarito is the causal agent and the virus natural reservoir is the rodent Zygodontomys brevauda (cane mouse). The disease affect agricultural male workers, between 14-54 years of age, mainly from Guanarito municipality of Portuguesa state and adjacent regions of Barinas State. Since VHF emergency in 1989 up till 1997, 220 cases have been reported with a fatality rate of 33%. Epidemiological informations suggest that VHF has a cyclic behaviour, with epidemic periods of high incidence, every 4-5 years. During the interepidemic periods few VHF cases are reported.

To determine the public's perception as to the general definition of an emergency medical condition (EMC), and to compare opinions between the general public and healthcare workers (HCW) on which specific medical conditions require emergency department (ED) care, a survey of people at 12 supermarkets and shopping malls in Northern California was conducted over a 6-month period in 1997. Individuals over age 18 were asked in person to complete a survey sheet. It asked participants to choose one of four definitions of "emergency medical condition." In addition, people were asked to determine which of 30 chief complaints they thought needed care in the ED. Demographic information was also collected. A second set of surveys asking the same questions was conducted among nonemergency healthcare providers at hospitals. Healthcare worker was defined as an MD, RN, LVN, or PA. A total of 1,018 members of the public and 126 healthcare workers completed the survey. EMC definitions selected by the public were: 1) an abbreviated federal EMTALA definition: a condition that may result in death, permanent disability, or severe pain (48.7%); 2) the federal definition plus other conditions preventing work (3.0%); 3) the federal definition plus any other conditions outside business hours (16.5%); and 4) any condition at any time as determined by the patient (31.6%). HCWs selected the following: definition 1 (71%); definitions 2 and 3 (0%); and definition 4 (27%). Definitions 1 and 3 were statistically different when comparisons were made between the public and HCWs. On the question of which of the 30 chief complaints needed care in an ED, agreement was seen between the public and HCWs for severe abdominal pain (94% vs. 99%, respectively) and severe chest pain (96% vs. 99%, respectively). However, the two disagreed on the need for ED care for severe headache (58% vs. 91%, respectively); mild chest pain (51% vs. 79%, respectively); and difficulty breathing (77% vs. 98%, respectively). No significant difference in opinions on the need for ED care was seen for some minor conditions: mild headache, sore throat, cough, flu symptoms, minor foot problems. No significant differences in answers occurred when age groups, occupations, or locations were compared. In conclusion, the public has split views concerning the general definition of an emergency medical condition. Approximately half uses a conservative federal definition, and half uses patient self-determined need as the definition. Data on which specific conditions need ED care provide additional insight on agreement between the public and HCWs on most problems. Both groups agree that many perceived minor medical complaints do not require ED care.

There are three clinical presentations of anthrax in humans: cutaneous (>95% of cases), orogastric and inhalational. The infectious form, the spore, enters the body and is thought to germinate within macrophages either at the site of inoculation (cutaneous or orogastric) or in the regional lymph node (inhalational). The bacillus then synthesizes its antiphagocytic capsule and the lethal and oedema toxins which interfere with the non-specific host defences leading to the characteristic locally destructive lesion and spread by lymphatics to the systemic circulation and other organs. The cutaneous form begins as a papule which progresses over several days to a vesicle and then ulcerates. There is often oedema, sometimes massive, probably due to the oedema toxin that surrounds the lesions which then develop a characteristic black eschar. The patient may be febrile with mild to severe systemic symptoms of malaise, headache and toxicity. Oropharyngeal anthrax presents with severe sore throat or an ulcer in the oropharyngeal cavity associated with neck swelling, fever, toxicity and dysphagia. Gastrointestinal anthrax begins with anorexia, nausea, vomiting and abdominal pain which may be similar to an acute abdomen. There may be diarrhoea and ascites, both of which may be haemorrhagic. Inhalational anthrax begins with non-specific symptoms of malaise, fever, myalgia and non-productive cough. After a period of 2-3 days, this is followed by a sudden onset of severe respiratory distress associated with diaphoresis, cyanosis and increased chest pain. There may be a widened mediastinum and pleural effusions on chest X-ray. Death follows in 24-36 h from respiratory failure, sepsis and shock. The diagnosis of anthrax is easy if it is considered. The organism is readily observed by Gram or Wright stain in local lesions or blood smear and can be easily cultured from the blood and other body fluids. However, because of its rarity, it is not often included in the differential diagnosis and in inhalational disease the diagnosis is rarely made until the patient is moribund. More rapid diagnostic tests are under development. Penicillin, combined with supportive care, remains the mainstay of treatment, although the organism is susceptible in vitro to many antibiotics. In recent years, there have been significant advances in our knowledge of the organism and its toxins and it is anticipated that similar progress will be made in the future in developing more rapid diagnostic tests and new modalities of treatment.

A fifteen-year-old boy was admitted to our hospital because of lower abdominal pain, watery diarrhea and mucobloody stool. Two years before admission, he was diagnosed to have Still's disease presenting with polyarthritis, sore throat, remittent fever and typical skin rash. He had been treated with non-steroidal anti-inflammatory agents, oral prednisolone and low-dose methotrexate. Although he was almost free of symptoms during the next two years, serum C-reactive protein (CRP) levels continued to be elevated moderately. He began to complain of lower abdominal pain and loose stool in May 1997 and came down with mucous-bloody diarrhea in June. Laboratory data on admission showed an elevated level of serum CRP (13.9 mg/dl). The biopsy of the stomach, ileum, sigmoid colon and rectum revealed the deposition of amyloid protein of AA type, which confirmed the diagnosis of secondary amyloidosis. The dose of prednisolone was increased and dimethyl sulfoxide per os or rectum was instituted, which improved his gastro-intestinal symptoms to some extent. However, fever, arthritis and diarrhea recurred along with tapered prednisolone dosage. In addition to gastro-intestinal symptoms, arrhythmia and proteinuria appeared. These symptoms were considered to reflect general deposition of amyloid in his body. He is now on immunosuppressive agent and high-dose prednisolone. Several studies report the higher frequency of gamma-allele of SAA 1 gene in the cases of rheumatoid arthritis with AA-amyloidosis than in those without. In the patient presented here, molecular biological analysis revealed that his SAA 1 gene was composed of beta- and gamma-allele. The presence of gamma-allele in his SAA 1 gene might be one of the factors that predisposed him for generalized deposition of amyloid protein in such a short period of time.
