Five- to six-week-old crossbred pigs weighing 5 to 14 kg were given purified cyclopiazonic acid at dosages of 10, 1.0, 0.1, and 0.01 mg/kg body weight orally for 14 days. Clinical signs observed by day 7 in pigs given 10 mg/kg body weight were weakness, inactivity, anorexia, rough hair coats, and reduced body weights. These pigs also developed diarrhea during week 2 of the experiment. The pigs given 1.0 mg/kg body weight had rough hair coats and were moderately inactive during the second week of the experiment. At necropsy, lesions were observed only in pigs given 10 and 1.0 mg/kg body weight of cyclopiazonic acid. Lesions were gastric ulcers, mucosal hyperemia, and hemorrhage throughout the small and large intestine in pigs given 10 mg/kg body weight of cyclopiazonic acid. The pigs also had yellow, fibrononecrotic material in the lumen of the small intestine and pale livers. One pig given 1.0 mg/kg body weight had gastric ulceration. Microscopic lesions in pigs given 10 mg/kg body weight were necrotizing gastroenteritis, focal hepatocellular necrosis, hepatic peripheral lobular fatty change, and focal renal tubular nephrosis with focal suppurative tubulointerstitial nephritis. Pigs given 1.0 mg/kg body weight of cyclopiazonic acid had necrotizing gastritis and villous blunting in the jejunum and ileum.

Studied were morphologically the organs of 10 cattle originating from two provinces of Cuba that suddenly succumbed ( muerte subita ). There were hemorrahagic diathesis, and histologically--general activation of the reticulo-endothelial system, nonsuppurative encephalomyocarditis, interstitial nonsuppurative hepatitis, nephritis, and pneumonia as well as catarrhal hemorrhagic gastroenteritis. In all cases there were among the lymphoid proliferations diffusely disseminated eosinophile leukocytes ( hyperergia ). This finding showed that the disease had run a subacute or chronic course which was made acute by the action of some stress factors (continuous running, intoxications oligoelement disturbances, etc.). The finding was also characteristic of reactive processes taking place under the action of some specific virus that probably took part in the etiology of the disease and required an intermediary host that remained unknown at the time.

The effect of consanguinity on fertility, reproductive loss, and development disorders were studied in South India. The population investigated included 377 unselected mothers who, along with their children, were followed up longitudinally. Each mother was interviewed regarding consanguinity, details of reproductive performance, and death of any offspring. Marriages were classified as unrelated or between uncle and niece, between first cousins, between first cousins once removed, between second cousins, between second cousins once removed, and between third cousins. Among the 377 marriages, 156 (41.4%) were consanguineous and 221 (58.6%) were nonconsanguineous. Consanguinity was more prevalent among Hindus than among Muslims or Christians. The mean and standard deviation in the age of women were similar in all age categories at the time of the study, but the numbers of pregnancies and live births were higher in consanguineous than in nonconsanguineous unions. The mean number of living children were not significantly different in the 2 groups. Although the intrauterine wastage showed no significant difference between the 2 groups, extrauterine loss of life, especially the death rate of children, was higher in the consanguineous marriages. The causes of death in the nonconsanguineous group were diptheria, tuberculosis meningitis, acute nephritis, convulsive disorder, and brain abscess. The causes of death in the consanguineous group were measles with complications, gastroenteritis, pyogenic meningitis, whooping cough, convulsive disorder, undiagnosed fever, burns, and undiagnosed illness with persistent vomiting. In regard to developmental anomalies, in only 1 instance was the condition unequivocally due to autosomal recessive inheritance. In the majority of the remaining cases the disorders were polygenic or multifactorial in origin. The frequency of developmental anomalies was significantly more frequent among the children of consanguineous parents.

An analysis has been made of causes of admission of black patients in 1991 to Murchison Hospital, Port Shepstone, Natal. Of 6675 total admissions, 6329 (95%) were classifiable. Of the latter, 1462 (23%) were aged 12 years and-younger, namely, 763 boys and 699 girls. Their chief causes of admission were pneumonia, gastroenteritis, trauma, acute glomerular nephritis, and malnutritional diseases. Of 4867 adults (73%), 1536 were males and 3331 females. Among men, chief causes were tuberculosis, congestive cardiac failure, hypertension and cerebral vascular accidents. Among women, apart from pregnancy, chief causes of admission were disorders of pregnancy, tuberculosis, congestive cardiac failure, pneumonia, diabetes, and hypertension. Of western diseases, 3.9% of adults were admitted for diabetes, and 2.8% for asthma. The general pattern of admissions is similar to that in other rural hospitals. The causes of admissions are discussed, regarding (1) public health improvements occurring, and (2) means of promoting further improvements by (a) community self-help, and (b) help from State health and other services.

A previously healthy 7-year-old white boy presented to St. Louis Children's Hospital with a 1-day history of headache, malaise, temperature of 38.7 degrees C, and a progressively erythematous, tender calf with central dusky purpura. On the morning of admission, his mother noticed a 2-mm crust on the patient's right calf with a 3-cm x 3-cm area of surrounding erythema. No history of recent trauma or bite was obtained. He had suffered two episodes of nonbloody, nonbilious emesis during the last day. In addition, over the previous 12 h, he presented brown urine without dysuria. His mother and brother had suffered from gastroenteritis over the previous week without bloody diarrhea. On initial physical examination, there was a 6-cm x 11-cm macular tender purpuric plaque with a central punctum on the right inner calf, which was warm and tender to the touch, with erythematous streaking towards the popliteal fossa (Fig. 1). The inguinal area was also erythematous with tender lymphadenopathy and induration, but without fluctuance. Laboratory studies included an elevated white blood cell count of 20, 800/microL with 6% bands, 86% segs, and 7% lymphocytes, hemoglobin of 12.5 g/dL, hematocrit of 35.1%, and platelets of 282,000/microL. The prothrombin time/activated partial tissue thromboplastin was 10. 4/28.0 s (normal PT, 9.3-12.3 s; normal PTT, 21.3-33.7 s) and fibrinogen was 558 mg/dL (normal, 192-379 mg/dL). Urinalysis showed 1+ protein, 8-10 white blood cells, too numerous to count red blood cells, and no hemoglobinuria. His electrolytes, blood urea nitrogen (BUN), and creatine were normal. The urine culture was negative. Blood culture after 24 h showed one out of two bottles of coagulase negative Staphylococcus epidermidis. The patient's physical examination was highly suggestive of a brown recluse spider bite with surrounding purpura. Over the next 2 days, the surrounding rim of erythema expanded. The skin within the plaque cleared and peeled at the periphery. The coagulase negative staphylococci in the blood culture were considered to be a contaminant. Cefotaxime and oxacillin were given intravenously. His leg was elevated and cooled with ice packs. The patient's fever resolved within 24 h. The lesion became less erythematous and nontender with decreased warmth and lymphadenopathy. The child was discharged on Duricef for 10 days. Because the patient experienced hematuria rather than hemoglobinuria, nephritis was suggested. In this case, poststreptococcal glomerulonephritis was the most likely cause. His anti-streptolysin-O titer was elevated at 400 U (normal, <200 U) and C3 was 21.4 mg/dL (normal, 83-177 mg/dL). His urine lightened to yellow-brown in color. His blood pressure was normal. Renal ultrasound showed severe left hydronephrosis with cortical atrophy, probably secondary to chronic/congenital ureteropelvic junction obstruction. His right kidney was normal.

Yersinia pseudotuberculosis, a food-borne pathogen, causes infection that commonly presents as gastroenteritis and mesenteric lymphadenitis. Post-infectious complications include erythema nodosum, reactive arthritis and, less commonly, uveitis and nephritis. Six serotypes of Y. pseudotuberculosis have been identified, and post-infectious complications have been identified following infection with some, but not all, serotypes. The first recognized outbreak of Y. pseudotuberculosis serotype lb occurred in British Columbia in November 1998. We documented the incidence of post-infectious complications and the effect of antibiotic use on the clinical course. Four months after the outbreak, a standardized questionnaire asking about symptoms and antibiotic use was administered by telephone to laboratory-confirmed cases. Stool samples were collected to examine for chronic carriage of Y. pseudotuberculosis and 59 of 74 eligible cases participated. The most common post-infectious symptoms were rash (8/59) and joint pain (7/59). Microbiological analysis, at follow-up, revealed 0/36 stools positive for Y. pseudotuberculosis. Seventy-eight percent of cases had taken antibiotics during their acute illness. There was no significant difference in the frequency of post-infectious symptoms between cases who had or had not taken antibiotics. The post-infectious pathogenicity of Y. pseudotuberculosis serotype lb is lower than that documented for other serotypes. Antibiotic use did not significantly alter the reported clinical course of illness.

The LD(50) +/- S.E. of tannic acid given orally to albino rats was found to be 2.26+/-0.083 g. per kg. body weight, which is higher than its apparent LD(50) when given per rectum. The immediate cause of death was respiratory failure preceded by convulsions when death occurred early and by hypothermic cachexia when death was delayed. Death was associated with a progressively developing hepatic necrosis and nephritis and a temporary acute gastroenteritis. It was accompanied by loss of weight and edema in many organs, evidence of stimulation of the spleen, adrenal cortex and testes, and atrophy of the thymus. Recovery in survivors was associated with a temporary increase in weight of the spleen and testes and persistence of loss of weight in the adrenal, pyloric stomach, and skin.

Adenoviral infections of immunocompetent patients usually present as self-limiting pharyngitis, gastroenteritis, urocystitis, or conjunctivitis. In immunosuppressed patients, development of the illness can be severe, even life-threatening or fatal, and therapeutical intervention is difficult. Previous case reports of adenoviral infections after kidney transplantation have described a symptomatology of hemorrhagic cystitis, fever, renal dysfunction, and rarely fatal systemic dissemination. Here we report on a 46-year-old female renal transplant recipient suffering from adenoviral serotype 35 nephritis of the donor organ 29 days after transplantation. In this case, the main symptoms of the adenoviral infection were high fever and progressive renal failure of the transplanted organ. At the peak of the clinical symptoms, owing to histological and immunohistochemical evaluations of a kidney biopsy, we were able to establish the diagnosis in time so that adequate therapy could be employed. Immunosuppression was reduced and modified, and a self-limiting course of the infection was observed, followed by significant improvement of graft function. Subsequent to histological diagnosis, adenoviral particles were isolated from urine and identified as adenovirus serotype 35. Adenoviral nephritis of the transplanted organ should be considered in the differential diagnosis of persistent anuria after kidney transplantation. Our case highlights the importance of applying all possible diagnostic techniques, including histological evaluation of renal biopsies.

Adenoviruses are responsible for a broad range of clinical diseases that may be associated with high mortality, including pneumonia, hepatitis, encephalitis, hemorrhagic cystitis, nephritis, and gastroenteritis in immunocompromised patients, including HIV-infected individuals. Here we report the identification of halo-substituted stavudine phenyl phosphoramidate derivatives as a new class of dual-function anti-HIV agents with potent and selective anti-adenovirus (ADV) activity. We examined the investigational stavudine phenyl phosphoramidate derivative stampidine and 12 structurally similar stavudine derivatives for anti-ADV activity. All 13 derivatives of stavudine, including stampidine, were substantially more potent than stavudine and inhibited ADV-induced plaque formation at nanomolar IC(50) values. Compounds with halo substitutions in the phenyl ring as well as the unsubstituted compound 607 were more potent than compounds with methoxy, methyl, or cyano substitutions. Compound 113 (stampidine) with a 4-Br substitution and compound 609 with a 4-Cl substitution were identified as the most potent lead anti-ADV agents. Compound 113/Stampidine inhibited ADV-induced plaque formation in skin fibroblasts in a concentration-dependent fashion with a mean (+/-S.E.M.) IC(50) value of 17 +/- 2 nM without any evidence of cytotoxicity even at 100 microM. Similarly, compound 609 inhibited ADV-induced plaque formation with an IC(50) value of 27 +/- 3 nM. We next sought to determine if the lead compounds 113 and 609 can also inhibit other viruses. Both compounds exhibited potent anti-HIV activity at nanomolar concentrations. However, neither compound exhibited any antiviral activity against non-HIV viruses, including Cytomegalovirus (CMV), Type I or Type II herpes simplex viruses (HSV-1, HSV-2), enterovirus ECHO 30, or respiratory syncytial virus (RSV) (IC(50) > 100 microM). The remarkable anti-ADV potency of the lead compounds stampidine and compound 609 warrants the further development of these promising new antiviral agents for possible clinical use in ADV infected patients.

This survey was performed on children with renal diseases admitted to Shiraz Pediatric Nephrology Unit from October 1993 to March 2000. There was a total of 1358 children, of whom 709 (52%) were boys, with age range of 1 month to 16 years and a mean of 6.5 +/- 4.7 years. Thirty percent of children were below age of 2 years. Admission diagnosis was acute nephritis in 312 (23%) patients, urinary tract infection in 259(19.1%), nephrotic syndrome in 252 (18.6%), chronic renal failure in 202 (14.9%), urologic problems in 101 (7.5%), acute renal failure in 99 (7.3%), metabolic disorders in 47 (3.5%) and hypertension in 39 (2.9%). Acute poststreptococcal nephritis was the most common disease in the acute nephritis group. Minimal change nephrotic syndrome was the most common in the nephrotic syndrome group (64.2%). Chronic renal failure was mainly due to congenital urological malformations (46%). Acute renal failure (ARF) was caused mainly by gastroenteritis. There were six cases of ARF due to scorpion sting and 12 cases due to various malignancies and associated tumorlysis syndrome. Persistent hypertension was caused mainly by reflux nephropathy (50%). We conclude that the patterns of renal diseases found in the Iranian children were similar to those reported from other developing countries with predominance of infection related diseases.
