Lethal multiple pterygium syndrome (LMPS) is an uncommon fetal-onset disorder of unknown etiology. The pathogenesis of LMPS has been suggested to be early-onset fetal akinesia, fragile collagen, or generalized edema. Information on the neuromuscular pathology of LMPS in the literature is generally scanty. We present the findings from a review of 14 fetuses with features of LMPS from the archives of the Hammersmith Hospital Perinatal Pathology Department. Autopsy reports, photographs, fetograms, and histological sections were examined, and additional special stains and immunostaining were performed on muscle sections. In five cases, there was evidence of autosomal recessive inheritance. One case was later shown to be due to glycogen storage disease type IV. The skeletal muscle bulk was reduced in all fetuses and the remaining muscle showed a range of histological appearances including vacuolar degeneration, dystrophy, a generalized or patchy myotubular appearance, and generalized hypotrophy. In one, the histological appearance was essentially normal. Two cases had abnormalities in the brain. Large motor neurons were present in the anterior spinal horns of all fetuses in whom the spinal cord could be examined. There was no evidence of cartilaginous joint fusion. We conclude that LMPS is the phenotype resulting from fetal akinesia commencing in the first or early second trimester. In the majority of cases, the precise underlying cause will not be identified, however, occasionally a metabolic or neurodevelopmental disorder or a specific primary myopathy may be demonstrated, providing adequate autopsy investigations are undertaken.  相似文献

The WHO clinical case definition for pediatric HIV infection has been designed to be used in countries where diagnostic laboratory resources are limited. We evaluated the WHO case definition to determine whether it is a useful instrument to discriminate between HIV-positive and HIV-negative children. In addition, clinical features not included in this case definition were recorded. We recorded clinical data from 300 consecutively admitted children in a state hospital in Bloemfontein, South Africa, and tested these children for HIV infection. A total of 222 children were included in the study; 69 children (31.1 per cent) were HIV positive. The sensitivity of the WHO case definition in this study was 14.5 per cent, the specificity was 98.6 per cent. Apart from weight loss and generalized dermatitis, the signs of the WHO case definition were significantly more often seen in HIV-positive than in HIV-negative children. Of the clinical signs not included in the WHO case definition, marasmus and hepatosplenomegaly especially occurred more frequently in HIV-positive children. Based on these findings we composed a new case definition consisting of four signs: marasmus, hepatosplenomegaly, oropharyngeal candidiasis, and generalized lymphadenopathy. HIV infection is suspected in a child presenting with at least two of these four signs. The sensitivity of this case definition was 63.2 per cent, the specificity was 96.0 per cent. We conclude that in this study the WHO case definition was not a useful instrument to discriminate between HIV-positive and HIV-negative children, mainly because its sensitivity was strikingly low. The simplified case definition we propose, proved to be more sensitive than the WHO case definition (63.2 vs. 14.5 per cent), whilst its specificity remained high.  相似文献

Branhamella catarrhalis was recovered from one blood culture each from three infants and one neonate admitted to the Trousseau Hospital (Paris) between 1986 and 1988. Clinical features included fever in every case, otitis in three cases, pneumonia in two cases, diarrhea in one case, and enterocolitis in one case. All the strains were beta-lactamase producers. Outcome was favorable in every case. The antimicrobial agent used was erythromycin in one case, amoxicillin in one case, and a third generation cephalosporin in two cases. We reviewed the pediatric literature for reports of Branhamella catarrhalis infections that seem more frequent or better detected than previously. The high prevalence of ampicillin-resistant strains is pointed out.  相似文献

This is a case of a 5-month-old female infant diagnosed with primary meningococcal pericarditis. Pericarditis is a well-recognized but uncommon complication of meningococcal infection. Primary meningococcal pericarditis, defined as purulent pericarditis without any clinical evidence of disseminated meningococcemia, meningitis, or other foci of meningococcal infection, is exceedingly rare, with only 21 reported cases since the first case was reported in 1939. This case report of primary meningococcal pericarditis is the youngest case and only the second case reported in an infant in the English literature to date.  相似文献

OBJECTIVES: Management of febrile infants and children remains controversial despite the 1993 publication in Pediatrics and Annals of Emergency Medicine of practice guidelines. Our aim was to determine the management of febrile infants and children by pediatric emergency medicine (PEM) fellowship directors and emergency medicine (EM) residency directors and compare their approach with the published practice guidelines. METHODS: Four case scenarios were sent to 64 PEM directors and 100 EM directors in the United States and Canada, describing four febrile, nontoxic infants and children aged 25 days (case 1), 7 weeks (case 2), 5 months (case 3), and 22 months (case 4). Respondents were asked to select which laboratory tests and radiographs they would obtain and to decide on treatment and disposition for each hypothetical case. RESULTS: Ninety-two percent (53/64) of PEM directors and 64% (64/100) of EM directors responded (overall response rate 74%). Compliance with the guidelines (PEM/EM) was 54%/16% for case 1, 31%/6% for case 2, 35%/19% for case 3, and 20%/11% for case 4. Only 11% of PEM and 2% of EM directors followed the guidelines for all four cases. Overall, directors performed fewer laboratory tests, ordered more chest radiographs and treated fewer patients with antibiotics than the expert panel suggested. EM directors ordered more chest radiographs (cases 1-4) and admitted more patients (case 2) than PEM directors. CONCLUSIONS: There is poor compliance with published practice guidelines in the management of febrile infants and children among PEM and EM directors.  相似文献

This article explores the length of time between key events in the criminal prosecution of child sexual abuse cases (charging decision, case resolution process, and total case-processing time), which previous research suggests is related to victims' recovery. The sample included 160 cases in three communities served by the Dallas County District Attorney. Most cases (69%) took at least 60 days for the charging decision, with cases investigated at the Children's Advocacy Center having a quicker time than either comparison community. Only 20% of cases had a case resolution time within the 180-day target suggested by the American Bar Association standard for felonies. Controlling for case characteristics, one of the three communities and cases with an initial arrest had a significantly quicker case resolution time. Total case processing generally took more than 2 years. Implications include the need to better monitor and shorten case resolution time.  相似文献

Two siblings with McArdle disease were studied biochemically and histochemically. Case 1 was a 9-year-old girl and case 2 was a 14-year-old boy. No elevation of serum lactate after exercise was noticed in both cases. PAS staining in case 1 was markedly increased, whereas in case 2 it was moderately increased. Muscle glycogen content in case 1 was 51 mg/gr muscle and in case 2 it was 38.7 mg/gr (control: 11.2 ± 1.28 mg/gr). Muscle phosphorylase activity was completely absent in case 1 and was about 50% of normal value in case 2, by both determinations of histochemical and direct biochemical methods. SDS-polyacrylamide gel electrophoresis revealed a little amount of muscle phosphorylase protein in both cases and also no abnormal migration of residual activity of muscle phosphorylase was found on polyacrylamide electrophoresis. These data indicate that occurrence of familial variety of muscle phosphorylase in two siblings was due to difference of muscle phosphorylase activity and also different onset of disease and clinical severity among two cases are depending on the degree of residual amount of the enzyme.  相似文献

Amniotic band syndrome (ABS) is a group of fetal malformations caused by fibrous adherences. Species such as sheep, rats, and mice have been used to study this syndrome. We developed a fetal rabbit model using 24 fetuses from punctured uteri. We found one case of syndactyly, one case of amniotic banding, two cases of extremity deformities, one case of a tail deformity, one case of head compression, and one case of open eyelids. Other malformations have been described in an amnion rupture sequence model (exencephaly and cleft palate). The rabbit fetus is an adequate model in which to develop this syndrome.  相似文献

We report on the case of an 8-month-old baby with blue rubber bleb nevus syndrome (BRBNS) presenting with recurrent bleeding from multiple haemangiomas in the colon and rectum. Treatment with Argon plasma coagulation resulted in long-term success. Our case is unique in that 1) it is the first documented case treated by argon plasma coagulation; 2) it is only the second case in the world literature with involvement of the genital tract; 3) it is the youngest patient treated endoscopically to date; 4) it is the endoscopically treated case with the longest follow-up; 5) it represents the second case of BRBNS reported from this part of the world; and 6) it expands the spectrum of mucosal lesions amenable to this new form of treatment. Argon plasma coagulation is a simple, inexpensive and effective treatment for selected lesions in BRBNS.  相似文献

We describe four classical cases of familial hemophagocytic lymphohistiocytosis (FHL), a macrophage-related, autosomal recessive fatal disorder. Parental consanguinity was present in three cases. All patients presented with fever, neurological involvement of varying degrees, hepatosplenomegaly, cytopenias, deranged liver function tests, and coagulogram, hypofibrinogenemia (three cases), and hyperlipidemia (one case). An antemortem diagnosis could not be made, although it was suspected in one case. Necropsy (done in three cases and postmortem liver biopsy in one case) revealed classical features of FHL. Florid lymphohistiocytic infiltrate exhibiting hemophagocytosis was seen in the bone marrow, liver, spleen, lymph nodes and brain (examined in two case). In addition to this, focal infiltrates were seen in the kidneys, lung, pancreas, testes, adrenals, and skin. Marked lymphoid depletion was seen in one case in the lymph nodes and spleen.  相似文献

Although case reports of hyperphosphatemia have been previously described in patients receiving liposomal amphotericin B, this has not been reported in patients receiving the lipid complex formulation. We report a case of hyperphosphatemia that persisted despite switching from liposomal to lipid complex amphotericin B in a child with invasive zygomycosis. This case suggests that in the context of acute renal dysfunction, hyperphosphatemia may also be observed with lipid complex amphotericin B. This case highlights the importance of differentiating between pseudohyperphosphatemia and hyperphosphatemia to prevent complications.  相似文献
