The erythrocyte sedimentation rate in syphilis

The erythrocyte sedimentation rate was studied in 520 men and 202 women with syphilis. It was raised in 66-6 per cent. of sero-negative primary cases, 80 per cent. of sero-positive cases, 100 per cent. of secondary cases, 80 per cent. of early latent cases, and 73-9 per cent. of late latent cases. It was also raised in sixteen out of seventeen cases of neurosyphilis and in all eleven cases of cardiovascular syphilis. It was concluded that the ESR had little place in the management of syphilis in general, but could be helpful in the post-treatment follow-up of late syphilis.     

Detection of GM-CSF in the sera of children with Langerhans' cell histiocytosis

GM-CSF induces proliferation and activation of Langerhans' cells in vitro. The density of Langerhans' cells in human tumours is correlated to the in situ density of GM-CSF, and intradermal injection of GM-CSF induces local accumulation of Langerhans' cells. Therefore, we investigated the presence of GM-CSF in the sera of children with Langerhans' cell histiocytosis (LCH). We detected GM-CSF in the sera of all children with disseminated and active LCH, but not in the sera of patients with localized (i.e. bone) LCH. These results suggest that GM-CSF level is related to extent and the activity of LCH.     

Nonmonotonous changes in erythrocyte sedimentation rate in whole blood

Scaphoid nonunion with avascular necrosis of the proximal pole remains a difficult problem. We have endeavoured to heal the fracture, restore scaphoid height and revascularize the proximal pole of the scaphoid by means of a vascularized dorsal interposition graft from the distal radius. The procedure has resulted in union of six of ten fractures. Fractures that healed had not been treated by a previous bone grafting procedure. Dissatisfaction was due to loss of motion in patients who had healed fractures, and pain in those patients with persistent non-unions.     

Association of malignancy and Langerhans' cell histiocytosis: report of three cases

Among 44 children with Langerhans' cell histiocytosis (LCH) seen at the Pediatric Department of the A.C. Camargo Hospital, S?o Paulo, Brazil, three developed malignancy, two before and one after the diagnosis of LCH. Malignancy could be attributed to treatment in one of the three children. Whether the cancer in the other two children represents a chance association of the two processes or is treatment-related, is unknown.     

Alterations in echinocyte transformation and erythrocyte sedimentation rate during hemodialysis

In spite of the popular belief that distraction is effective in coping with pain, there is evidence that a neutral distractor does not reduce people's reports of pain. However, it may be that distraction's effect is not detectable in immediate ratings, when the need to rate the pain forces the sufferer to concentrate on it. Instead, after a delay, when the pain itself is gone and the person must base the judgment on a memory of the event, having been distracted may attenuate the recalled pain. An experiment with 72 undergraduate participants tested this proposition, with 1 group highly distracted during cold-pressor pain and 1 group slightly distracted. Half of each group rated the pain immediately, and half waited 10 min after the event to rate the pain. The participants who gave immediate ratings showed no effect of distraction, but for participants who waited 10 min before giving their ratings, high distraction led to reduced reports of pain.     

Study of erythrocyte sedimentation rate in patients with pulmonary tuberculosis

We studied the erythrocyte sedimentation rate (ERS) and related factors that influence ESR in 326 patients with Pulmonary tuberculosis. The ESR tended to be higher for aged subjects and showed a difference between patients under 59 years old and patients over 60 years old. Besides, patients under 30 years old tended to present lower ESR. It is suggested that they may be under the influence of inapparent infection. For The Japanese Society for Tuberculosis Classification, a significant difference was noted in the extent, but there was no difference about the presence of cavity. A significant correlation was detected between ESE and Gaffky scale, ESR and CRP, and ESR and period until sputum culture became negative. But CRP negative cases were observed in about 28%. CRP alone was not sufficient for the evaluation of the morbid condition of Mycobacterium infection. Receiver-Operator Characteristic curve analysis confirmed that ESR is useful among patients with pulmonary tuberculosis. Therefore evaluation of ESR together with CRP was needed.     

Langerhans' cell histiocytosis of the spine: use of MRI in guiding biopsy

The MRI features of two cases of spinal Langerhans' cell histiocytosis with multilevel involvement are presented in which MRI was of help in differentiating active from inactive healing lesions by the demonstration of signal changes in the vertebral body marrow of the active lesion, manifest as low signal intensity on T1-weighted sequences and high signal intensity on T2-weighted sequences. This distinction could not be made by plain radiography or bone scintigraphy. In cases where biopsy is required for diagnosis, MRI is recommended to guide the biopsy towards levels suggestive of active involvement.     

Study on long-term biological variability of erythrocyte sedimentation rate

Thanks to progress in serologic techniques evidence was obtained in 1980 showing that acute hepatitis epidemics observed in India were due to neither virus A nor virus B. The presence of another virus was confirmed and its genome was cloned and sequenced in 1991. Hepatitis virus E is a small RNA virus that differs from other known human viruses. Man and probably a few animal species maintain dissemination by the fecal route. Subjects not previously contaminated are susceptible and produce protective antibodies. Contamination occurs by the fecal-oral route general from water or tainted food. Direct contamination is rare. Vertical transmission from mother to fetus can also be observed. Outbreaks of the disease are characterized by epidemic proportions, preferential involvement of adolescent and young adults, and high incidence of fulminant cases especially in pregnant women. Outbreaks have been observed in endemic settings in southern Asia, Africa, and Mexico where sporadic cases are observed. Endemic areas are found in all developing countries. Hepatitis E is not clinically different from other acute viral hepatitis. Asymptomatic forms are common especially in children. The course of the disease is usually benign with little risk of development of chronic symptoms and cirrhosis. However hepatitis E is associated with a high incidence of severe cases with a mortality of 1 to 2% from icteric forms which occur in 15 to 20% of cases involving women contaminated during the last three months of pregnancy. Diagnosis can be made using either synthetic proteins or recombinant peptides. for the epitopes of the virus. Prevention depends on protection of the water supply and proper sewage disposal. Successful active immunization of monkeys holds promise for development of a vaccine. Due to its magnitude and high mortality rate hepatitis E is a major health problem for numerous regions around the world including Southeast Asia.     

Localized eosinophilic granuloma (Langerhans' cell histiocytosis) of the orbital frontal bone

Four patients (aged 5, 8, 14, and 51 years at initial manifestation) with isolated eosinophilic granulomas of the orbital frontal bone displayed short symptomatic periods (two weeks to three months) and some combination of erythema of the lids, a soft, palpable anterior orbital mass, periorbital pain, and osteolytic bone lesions on roentgenography. The bone lesions roentgenographically exhibited irregular, serrated, and sclerotic margins, distinguishing them from the more oval appearance of dermoid cysts. Electron microscopy performed in one case disclosed the presence of Langerhans' granules in the cytoplasm of the histiocytes, indicating that the orbital disease is a mild form of "histiocytosis X" and a benign proliferation of a specific kind of histiocyte--the Langerhans' cell. On follow-up (two to 20 years), after incomplete curettage of two lesions coupled with low doses of postoperative radiotherapy, there was reconstitution of the bone defects, whereas more extensive surgery performed on the other two patients resulted in permanent but subclinical bone defects.     

The sonographic appearance of lesions of the spleen and pancreas in an infant with Langerhans' cell histiocytosis

Langerhans' cell histiocytosis (LCH), the term now used to describe the group of diseases known as histiocytosis X, is a rare disorder of the bone marrow-derived histiocytes that may involve the skin, bone, bone marrow, liver, spleen, lungs, lymph nodes, and rarely the pancreas. Sonographically demonstrable lesions of the spleen and pancreas have not been reported. We present a case of disseminated LCH in a 4-week-old infant to demonstrate the sonographic appearance of splenic and pancreatic lesions that occur with this disease.     

Comparison of factor VIII-related antigen and erythrocyte sedimentation rate in outpatient management of vasculitis

Electroimmunodiffusion (Laurell rocket) determinations of factor VIII-related antigen in plasma were ordered to determine the cost/benefit ratio for factor VIII-related antigen as a putative test for endothelial damage in suspected vasculitis. Twenty-seven consecutive patients referred for vasculitis or suspected vasculitis were identified and followed up for an average of 9.1 +/- months (range: one to thirty-three months) in a prospective, unblinded study performed in a clinic, associated with a 1054-bed inner-city university hospital. There was no difference in Westergren erythrocyte sedimentation rate (WESR) in patients with final diagnosis of systemic vasculitis (SV) (38 +/- 12 mm/hour) compared to those without vasculitis (NV) (27 +/- 7) as the final diagnosis. The mean plasma concentration of factor VIII-related antigen was significantly elevated in SV (344 +/- 100%) when compared with NV (147 +/- 39%) (P < 0.016). The factor VIII-related antigen test in this study was 2.56 times more likely (crude odds ratio) than the WESR to contribute to a change in diagnosis or therapy (P = 0.016). Positive and negative predictive values (PPV and NPV) for factor VIII-related antigen (abnormal at greater than 220% of the normal value) were both 70%. PPV and NPV for WESR were 56% and 86%, respectively. The factor VIII-related test was less cost-effective than the WESR in the follow-up period unless it was important to define complete remission or differentiate vasculitis flare from infection. The authors conclude that factor VIII-related antigen is a useful test in the initial diagnosis of vasculitis.     

Cathepsin D and E co-expression in sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) and Langerhans' cell histiocytosis: further evidences of a phenotypic overlap between these histiocytic disorders

Nosological classification of sinus histiocytosis with massive lymphadenopathy (SHML; Rosai-Dorfman disease) is difficult, and the normal cellular counterpart of Rosai-Dorfman (RD) cells is uncharacterised. The peculiar S-100+ phenotype of RD cells suggests a relationship with the dendritic cell family. Recent investigations have revealed cathepsin E to be selectively concentrated in antigen-presenting cells, whereas cathepsin D was found to be expressed in cells of macrophage lineage. Cathepsin D and E distribution was investigated by immunohistochemistry in a series of SHML biopsies and in two types of dendritic cell proliferative lesions: dermatopathic lymphadenitis (DL) and Langerhans' cell histiocytosis (LCH). In SHML biopsies, RD cells and monocyte-related elements of the sinuses and pulp coexpressed cathepsin D and E. LCH cells also stained for both these aspartic proteinases. Conversely, in DL cathepsin E and D were localised to separate cells that resembled Langerhans' cells (LC) or macrophages, respectively, in morphology and distribution. Our data outline the peculiar immunophenotype of RD and LCH cells and suggest that caution should be exercised in the identification of their normal cellular counterpart. The common expression of cathepsin D and E and of S-100 protein suggests some phenotypic overlap between SHML and LCH cells, despite their striking morphological divergence.     

Primary Langerhans' cell histiocytosis of the central nervous system with fatal outcome. Case report

An unusual case of primary parenchymal Langerhans' cell histiocytosis of the central nervous system is reported. The definitive diagnosis was obtained by ultrastructural detection of Birbeck granules and by immunohistochemical evidence of CD1a expression. Despite complete surgical resection, there was an early recurrence with multiple central nervous system metastases leading to a fatal outcome.     

White blood cells, C-reactive protein and erythrocyte sedimentation rate in pneumococcal pneumonia in children

PURPOSE: To profile cancer patients aged 80 and older undergoing radiotherapy and to study the tumor response and side effects of therapy. METHODS AND MATERIALS: We retrospectively analyzed the records of patients aged 80 and older who received radiation therapy at James A. Haley Veterans Hospital and H. Lee Moffitt Cancer Center between 1988 and 1995. A total of 203 patients aged 80-94 received radiotherapy during this period. Treatment sites included head and neck [50], breast [16], chest [37], pelvis [53], and miscellaneous [39]. Age, treatment site, field size, total dose, response to treatment, treatment interruptions, incidence and severity of weight loss, myelosuppression, diarrhea, mucositis, dermatitis, and follow-up status are assessed using our departmental records and hospital tumor registry. RESULTS: Of 191 patients evaluated, 179 (94%) completed the treatment without serious complications. A total of 195 sites were irradiated. Twelve patients (6%) required interruption of the treatment. Therapeutic responses were seen in 86 out of 112 patients (77%) treated with curative intent (with 67% complete response) and in 67 out of 83 patients (81%) treated with palliative intent. The causes of treatment interruptions included weight loss from diarrhea, dysphagia, and progressive disease. Treatment interruptions were more likely in patients treated with large treatment fields. In patients treated for upper aero-digestive tract cancer, Grade 3 and 4 mucositis was noted in 20 and 2% of patients, respectively. Grade 1 and 2 enteritis was noted in 43% of patients treated for pelvic malignancies. Grade 3 dermatitis was noted only in 2% of patients. CONCLUSION: Radiotherapy is highly effective and well tolerated by the oldest old. Age is not a contraindication to aggressive radiotherapy.     

Langerhans' cell histiocytosis and juvenile xanthogranuloma of the orbit. Clinicopathologic, CT, and MR imaging features

The clinical, radiologic, and histopathologic features of two main disorders of the orbit are discussed. Group I, Langerhans cell histiocytosis (histiocytosis X, Class I), is caused by proliferation of X histiocytic Langerhans' cells. Group II is juvenile xanthogranuloma, and Class II is related to the proliferation of non-X histiocytic (monocyte-macrophage) cells. The two diseases are of unknown cause and differ in their clinical, radiologic, and histopathologic features.     

Central nervous system disease in Langerhans cell histiocytosis

Central nervous system (CNS) disease in Langerhans cell histiocytosis (LCH) is a poorly understood complication of yet unknown frequency. By far the most common manifestation is in the hypothalamic-pituitary system with diabetes insipidus as the leading sign, followed by other endocrinopathies and hypothalamic dysfunction. However, essentially all other parts of the CNS may be involved. On the one hand, space-occupying histiocytic infiltrates may lead to size- and site-depending symptoms, extending from adjacent bone lesions or arising from the meninges or choroid plexus. On the other hand, a progressive neurological deterioration can occur with mainly cerebellar-pontine symptoms. In this article, these clinical patterns are described in correlation with the morphology on MR imaging and histopathology. Further, the therapeutic strategies are reviewed critically, and guidelines for the management of patients with LCH-related CNS disease are presented.     

Elevated heart rate variability in physically active young and older adult women

OBJECTIVE: To determine if participation in group sessions as part of health supervision visits for infants improves outcomes compared with individual visits in high-risk mothers. STUDY DESIGN: Randomized controlled clinical trial. PARTICIPANTS: Mothers of young infants who had at least 1 of the following risk factors: aged younger than 20 years at delivery, participation in Medicaid, less than a high school education, previous or ongoing substance abuse, or history of abuse as a child. SETTING: Two urban university pediatric clinics in Seattle, Wash. INTERVENTIONS: Mother-infant dyads were randomized to receive group well-child care (GWCC) or individual well-child care (IWCC) before the infant was 4 months old; the intervention continued until the child was 15 months old. Mothers completed the Sense of Competence and Social Isolation subscales from the Parenting Stress Index and Sarason's Social Support Questionnaire at enrollment and again on completion of the study. During the 11-month study period, 7 health supervision visits were scheduled for each mother-infant dyad. Social workers met periodically with mothers during the study and assessed the following functional outcomes: return to school, return to work, enrollment in a substance abuse treatment program, and becoming pregnant. In addition, data on study children were collected from Child Protective Services to assess referrals because of suspected abuse and/or neglect. RESULTS: Data were collected on 213 mother-infant dyads, including 108 who received GWCC and 105 who received IWCC. At the conclusion of the study period, similar proportions of GWCC and IWCC mothers scored in the high-risk range on the Sense of Competence subscale, Social Isolation subscale, and the Social Support Questionnaire (P=.57, .32, and .59, respectively). For more than 50% of the mothers, scores on the Sense of Competence and Social Isolation subscales deteriorated during the study period from the not-high-risk range to the high-risk range, regardless of assignment to GWCC or IWCC. No differences were noted between GWCC and IWCC mothers for any functional outcome. During the study period, 8.8% of children receiving GWCC were referred to Child Protective Services vs 8.3% of those receiving IWCC (P=.85). CONCLUSION: The format of well-child care may not be an important determinant of outcomes among high-risk mothers.     

Elevated diet-induced thermogenesis and lipid oxidation rate in Crohn disease

OBJECTIVE: To examine the relationship between antimalarial therapy and total cholesterol in patients with systemic lupus erythematosus (SLE) with or without steroid therapy. METHODS: Retrospective study for the University of Toronto Lupus Clinic database between 1976 and 1997. The effects of antimalarials on random total cholesterol levels were assessed in the following situations: patients not receiving steroids (part I) that either initiated or discontinued antimalarials; patients receiving steroids (part II) that were either on a stable dose or initiating antimalarials; and patients initiating steroids with or without antimalarials (part III). Paired t test, Fisher's exact test, and 2 way analysis of variance were used when appropriate. RESULTS: Initiation of antimalarials reduced the baseline total cholesterol by 4.1 % at 3 months in 53 patients (p = 0.020) and by 0.6% at 6 months in 30 patients (p = NS), while the cessation of antimalarials increased the total cholesterol by 3.6% at 3 months in 38 patients (p = NS) and 5.4% at 6 months in 22 patients (p = NS). In 181 patients taking steroids and antimalarials, the mean total cholesterol was 11% less than for 201 patients receiving a comparable dose of steroids alone (p = 0.0023). Initiation of antimalarials on a stable dose of steroids reduced the total cholesterol by 11.3% at 3 months in 29 patients (p = 0.0002) and 9.4% at 6 months in 20 patients (p = 0.004). For patients initiating steroids, the percentage increase in cholesterol was lower in those taking antimalarials compared to patients without antimalarial therapy (p = 0.0149). CONCLUSION: Antimalarials lower total cholesterol in patients receiving steroids and may minimize steroid induced hypercholesterolemia.     

Serum sialic acid and its relationship to various haematological parameters, including erythrocyte sedimentation rate

Policies regarding ambulance diversion are critical to ensuring that EMS providers are aware of appropriate patient destinations, even before patients enter the system. Field EMS personnel should never be requested to prolong transport time intervals to search for an available hospital at the potential expense of patients' conditions and the immediate availability of out-of-hospital emergency care for the community. The responsibility for providing efficient emergency care to the community rests with all those who contribute to EMS structures and processes. All EMS system participants, including hospitals, EMS providers, local and regional lead agencies, and medical oversight authorities, must work together to create comprehensive ambulance diversion policies that satisfactorily meet each other's needs, while maintaining the highest regard for the needs of EMS patients and the entire community.
