Haemolytic uraemic syndrome in the defined population of Northeast of Scotland

Twenty seven cases of haemolytic-uraemic syndrome (HUS) were admitted to the Royal Aberdeen Children's Hospital between 1978 and 1989. All cases were from the defined childhood population of the Grampian region of Northeast of Scotland. Thirteen cases were admitted during the 2-year period 1987–1988 (Group 1). Of the 13 cases, 9 (Group 1a) were admitted within the 11-month period between August 1987 and June 1988, and were from a small area (7 miles radius) within and around the City of Aberdeen. Their mean age was 7.1 years. Twelve cases of HUS were admitted between 1978 and 1986 and 2 cases were admitted in 1989 (total 14 cases; Group 2). Mean age was 3.0 years with no geographical clustering. The average annual incidence for group 2 was 1.25 per 100,000 children 0–16 years old.     

Direct activity of human T lymphocytes and natural killer cells against Cryptococcus neoformans.

Lymphocytes constitute a critical component of host defenses against cryptococcosis. Previously, we demonstrated that human lymphocytes cultured with interleukin-2 formed conjugates with, and directly inhibited the growth of, Cryptococcus neoformans. Here, we explore the anticryptococcal activity of freshly isolated, highly purified populations of human peripheral blood lymphocytes. Lymphocytes were incubated with encapsulated C. neoformans for 24 h, after which the lymphocytes were lysed, dilutions and spread plates were made, and CFU were counted. Fungistasis was determined by comparing growth in wells with and without lymphocytes. Nylon wool-nonadherent peripheral blood mononuclear cells (NWNA PBMC) were highly fungistatic, even if either T cells or natural killer (NK) cells were depleted by panning. A mixed population of T cells and NK cells, obtained by rosetting NWNA PBMC with sheep erythrocytes, completely inhibited cryptococcal growth, whereas the nonrosetting cells had little fungistatic activity. CD4+, CD8+, and CD16/56+ lymphocytes, isolated by positive immunoselection, had potent growth-inhibitory activity. In contrast, purified B cells had no activity. Fungistasis was seen even in the absence of opsonins. Antifungal activity was markedly diminished when surface receptors on NWNA PBMC were cleaved by treatment with trypsin or bromelain. Supernatants from stimulated lymphocytes or concentrated lymphocyte sonicates were not active. Lymphocyte-mediated fungistasis was seen with two different strains of C. neoformans. CD4+, CD8+, and CD16/56+ lymphocytes formed conjugates with C. neoformans, as observed under Nomarski differential interference contrast microscopy and videomicroscopy. These data demonstrate that freshly isolated peripheral blood T cells and NK cells have the capacity to bind and directly inhibit the growth of C. neoformans.     

Radiculopathy following intrathecal baclofen pump implantation]

INTRODUCTION: Intrathecally delivered baclofen has been used as a treatment for severe spasticity since 1984. After a successful intrathecal baclofen trial, a programmable drug delivery system was implanted. Few early complications such as infection or hematoma are observed after this surgery. OBJECTIVE: To describe an unusual and unknown complication of intrathecal baclofen therapy. METHOD: We report 2 cases of complications of intrathecal baclofen therapy, radiculalgy, that appeared early after pump implantation. The clinical symptoms and computed tomography (CT) results are described. RESULTS: The first patient described pain, which evoked left S1 radiculopathic features. The second had left L5 radiculopathic involvement. The mean pain level was estimated on a 10-point visual analog scale as 7.5 (range 4-9). Lumbar CT scan showed a conflict between the symptomatic root and the catheter and eliminated other causes of the symptoms. Treatment with analgesic drugs was successful in 1 patient. The other presented with proximal disconnection of the catheter, which led to surgical replacement of the catheter. The pain disappeared after this surgery. CONCLUSION: Intrathecal baclofen therapy with a subcutaneously implanted progammable pump can be complicated by radiculalgy secondary to a conflict between the catheter and symptomatic root. The diagnosis is made by CT lumbar scan. If medical treatment is not sufficient, surgery could be proposed to replace the catheter.     

Pure partial trisomy for long arm of chromosome 9.

A case of a 4-year-old boy with trisomy of the long arm of chromosome 9 is described (46,XY, der (9), t (9;9) (q32;q12)). The trisomy is probably the result of a translocation of the long arm of the chromosome from one homologue to the other in a parental gonad. The clinical features of the child which include severe developmental retardation, bird-like facies, tapered fingers, and flexion contractures of the legs are similar to those of the few cases described of trisomy of the whole chromosome.     

Ectodermal dysplasias: Classification and organization by phenotype,genotype and molecular pathway

An international advisory group met at the National Institutes of Health in Bethesda, Maryland in 2017, to discuss a new classification system for the ectodermal dysplasias (EDs) that would integrate both clinical and molecular information. We propose the following, a working definition of the EDs building on previous classification systems and incorporating current approaches to diagnosis: EDs are genetic conditions affecting the development and/or homeostasis of two or more ectodermal derivatives, including hair, teeth, nails, and certain glands. Genetic variations in genes known to be associated with EDs that affect only one derivative of the ectoderm (attenuated phenotype) will be grouped as non‐syndromic traits of the causative gene (e.g., non‐syndromic hypodontia or missing teeth associated with pathogenic variants of EDA “ectodysplasin”). Information for categorization and cataloging includes the phenotypic features, Online Mendelian Inheritance in Man number, mode of inheritance, genetic alteration, major developmental pathways involved (e.g., EDA, WNT “wingless‐type,” TP63 “tumor protein p63”) or the components of complex molecular structures (e.g., connexins, keratins, cadherins).     

Rising incidence of type 1 diabetes in Scottish children, 1984-93. The Scottish Study Group for the Care of Young Diabetics

OBJECTIVES: To calculate the incidence of type 1 diabetes in Scottish children aged less than 15 years between 1984 and 1993; to examine changes in incidence; and to calculate the prevalence of diabetes at the end of this period. DESIGN: Three data sources were used to construct the Scottish Study Group for the Care of Young Diabetics register: active reporting of all new cases; reports from the Scottish Morbidity Register 1; and local registers. SUBJECTS: All children resident in Scotland diagnosed with primary insulin dependent diabetes mellitus when less than 15 years of age between 1984 and 1993. MAIN OUTCOME MEASURES: Annual incidence and prevalence rate for Scotland; time trend in incidence over the 10 years; differences in incidence between the three different age groups; and completeness of the register. RESULTS: The average annual incidence for Scotland was 23.9/100,000 children. The prevalence rate was 1.5/1000 in 1993. A total of 2326 cases was identified from the three sources. Capture-recapture analysis suggests a case ascertainment of 98.6%. The annual incidence rates increased at a rate of 2% each year (rate ratio = 1.02, 95% confidence interval (CI) 1.01 to 1.03). The incidence was higher in boys than girls (rate ratio = 1.08, 95% CI 1.00 to 1.18), and the incidence rates increased with age: 15.3/100,000/year for age 0-4 years, 24.4/ 100,000/year for age 5-9 years, and 31.9/ 100,000/year for age 10-14 years. CONCLUSIONS: The incidence of type 1 diabetes in Scotland is increasing and the prevalence is relatively high. These findings have important implications for health service resource allocation. The Scottish Study Group for the Care of Young Diabetics' register provides a base for monitoring and research.     

Multivisceral organ failure related to leptospirosis in pregnant patient

Leptospirosis is the most widespread zoonosis in the world. It is caused by pathogenic leptospira infection. This infection is also an uncommon cause of hepatorenal failure. Indeed, hemolysis, elevated liver enzyme levels and low platelet count syndrome, and acute fatty liver of pregnancy are specific to the pregnant state. Leptospirosis is rarely described in pregnancy; it might mimic puerperal sepsis or hepatorenal failure associated with pregnancy induced hypertension. We report a case of leptospirosis presenting as multiple organ failure during third trimester of pregnancy with a good outcome.
