This study was undertaken in order to estimate the incidence of leukemia among Koreans. Medical records were studied of patients with diagnoses of either ICD-9 038 (septicemia), or 204-208 (leukemias), or 284 (aplastic anemia), or 289 (other diseases of the blood and blood-forming organs) in the claims sent in by medical care institutions throughout the country to the Korea Medical Insurance Corporation (KMIC) during the period from January 1, 1986 to December 31, 1987. These records were abstracted in order to identify and confirm new cases of leukemia among the beneficiaries of KMIC, which covers about 10% of the whole Korean population. Using these data from the KMIC, the incidence rates of leukemia among Koreans were estimated as of July 1st, 1986 to June 30, 1987. The crude incidence rate of all types of leukemia among Koreans is estimated to be 3.45 (95% CI; 0.77-9.55) and 2.29 (95% CI; 0.28-7.81) per 100,000 in males and females, respectively. The cumulative rate for the age span 0-64 is 0.25% in males and 0.18% in females, and for the age span 0-74, 0.35% in males and 0.23% in females. The adjusted rates for the standard world population are 3.90 and 2.48 per 100,000 in males and females, respectively. The relative frequencies by type are 51.5% for AML, 21.6% for ALL, 20.2% for CML, and only 1.5% for CLL. The incidence patterns of various types of leukemia, of which this is the first report in Korea, are analyzed and presented.(ABSTRACT TRUNCATED AT 250 WORDS)

The validity of the official information on the cause of infant deaths was studied in the Brazilian cities of Porto Alegre and Pelotas in 1985. Using data collected for a population-based case-control study of infant mortality due to infectious diseases or malnutrition, a comparison was made between the causes of death reported on the death certificates and those obtained after a careful review of case-notes and a medical interview with the parents of the decreased infants. Official death certificates showed an excess of deaths attribute to bronchopneumonia (ICD 485X) and septicemia (ICD 038.9), and an underestimation of the number of deaths due to diarrheal diseases (ICD 009.1) and of sudden infant deaths (ICD 798.0). The overall rate of agreement between official and revised certificates, in terms of groups of causes of death, was only 27.9%. Lower respiratory infections, which were the leading infectious cause of infant death according to official statistics, were superseded by diarrheal diseases after this revision.

The most common diagnoses of elderly patients in the emergency department (ED) were compared among three age subgroups: 65 to 74, 75 to 84, and 85 and older. The computerized billing records for patient visits to 10 northern New Jersey hospital EDs for the years 1985 to 1991 were retrospectively analyzed. The most frequently occurring ICD-9-CM codes for elderly patients were compared among the three age subgroups. Elderly persons comprised 174, 146 (14% of the total) patient visits. The 176,146 patient visits were assigned 259,440 ICD-9-CM codes. The most common ICD-9-CM codes for medical diagnoses included chest pain, cardiac dysrhythmias, congestive heart failure, syncope, abdominal pain, and dyspnea. Fractures, particularly of the lower limb and upper limb; contusions; open wounds, particularly of the head, neck, and trunk; and falls were among the most common trauma diagnoses. The proportions in the three age subgroups of each diagnosis were statistically significantly different, except for cardiac arrest and contusions of the trunk and of multiple sites. The diagnoses with clinically significant higher relative risks in older age subgroups were atrial fibrillation, congestive heart failure, syncope, hypovolemia/dehydration, gastrointestinal hemorrhage, dyspnea, pneumonia, pulmonary edema, cerebrovascular accident, septicemia, urinary tract infection, fractures, and open wounds of the head, neck, trunk, particularly the scalp, and falls. Clinically significant lower relative risks were found in older age subgroups for chest pain, acute myocardial infarction, hypertension, angina, chronic airway obstruction not elsewhere classified, epistaxis, contusions of the upper limb, and open wounds of the finger.

Studies have used medical record discharge data as coded by the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) to estimate pneumococcal pneumonia incidence and vaccine efficacy. However, the accuracy of coding data to identify laboratory-confirmed pneumococcal pneumonia is not known. With the use of information collected in Ohio for a community-based pneumonia incidence study, the authors calculated the sensitivities, specificities, positive predictive values (PPV), and negative predictive values (NPV) of specific codes for pneumococcal pneumonia among hospitalized patients with community-acquired pneumonia. Sensitivities of the most common ICD-9-CM codes listed in the first five positions for patients with laboratory-confirmed pneumococcal pneumonia were 58.3% (code 481.0, pneumococcal pneumonia), 20.4% (38.0, streptococcal septicemia), 19.2% (38.2, pneumococcal septicemia), 15.0% (518.81, respiratory failure), 14.2% (486.0, pneumonia, organism unspecified), and 11.3% (482.3, streptococcal pneumonia). Using the first five listed ICD-9-CM codes rather than just the first listed code increased sensitivity without causing substantial change in specificity, PPV, and NPV. Sensitivity, PPV, and NPV of individual and groups of codes varied with different case definitions of pneumococcal pneumonia. Incidence and vaccine efficacy studies with the ability to validate diagnoses by medical chart review can use a combination of many ICD-9-CM codes to maximize sensitivity. However, without the ability to review medical charts, researchers must carefully decide which codes would best suit their studies.

Decreasing of number of cases as well as incidence rate of hepatitis type B and type A, and increasing of pertussis, leptospirosis, encephalitis and some other diseases was noted in Poland in 1997. The biggest percentage of deaths was caused by tuberculosis--43.1%, sepsis--over 21.9% and hepatitis--10.6%. Introduction of ICD-10 as well as strikes of health workers in Poland in 1997 caused undernotification especially of deaths.

Childhood idiopathic thrombocytopenic purpura (ITP) is a common disorder. However, single-institution, long-term, natural history data are limited. The objective of this paper is to review presenting features, response to therapy, and natural history of ITP treated at a single pediatric academic medical center. A retrospective chart review was made for all children (ages birth-18 years) diagnosed with ITP (ICD 287.3) and treated at the Childrens Hospital of Alabama/University of Alabama at Birmingham between 1993 and 2003. Four hundred nine patients were identified (49% male, 51% female; mean age: 5.85 years; range: 1 month-17 years). There was no seasonal variation of presentation. The mean platelet count was 19k (0-120k). Bone marrow aspiration (BMA) was performed in 72% but altered the diagnosis or therapy in no patient. Treatment consisted of corticosteroids in 256 (92% response), intravenous immunoglobulin (IVIG) in 125 (87% response), Win-Rho D in 58 (91% response), and no therapy in 71 (100% response). Response was defined as increase in platelet count to > 50k. There was no difference in response to any therapy. No patients died. One patient presented with a CNS hemorrhage at presentation, responded to therapy, and survived. Twenty-three of 409 patients (6%) experienced clinical bleeding requiring hospitalization or blood transfusion. Chronic ITP (persistence > 6 months) was noted in 99 patients (24%). Chronic patients presented at an older age (7.8 vs 5.2 years for acute only, p<0.001), and with higher platelet counts (27k vs 17k, p<0.001). The risk of chronic ITP was partially predicted by presenting platelet count > 50k and age > 10 years, or both; 50% of patients presenting with these features developed chronic ITP vs 24% overall rate. Splenectomy was curative in 30/31 (97%) patients. There was no postsplenectomy sepsis. Of 99 patients with chronic ITP, 25 responded to splenectomy, 37 resolved at a mean of 20.3 months after diagnosis (7-96 months), 36 had persistent mild thrombocytopenia (50k-125k), and 1 failed to respond to any treatment including splenectomy. Overall, 91% of cases resolved with therapy or observation. ITP is a common pediatric disease presenting at any age with low morbidity and mortality. Most cases can be managed by pediatricians without hematology referral. Several equally successful therapeutic options exist. Chronic cases present at an older age with higher platelet counts. Up to 50% of cases of chronic ITP will resolve with ongoing follow-up. The overall prognosis in childhood ITP is excellent.

We analysed data from 33741 patients with ICD-10-AM-defined sepsis from an Australian hospital morbidity dataset to investigate the relationships between specific types of organisms, potential risk factors for infection, organ dysfunction, ICU utilization and hospital mortality. A total of 24% of patients received some of their care in an intensive care unit, and the overall hospital mortality rate was 18%. Gram-positive bacteria were isolated in 27% of cases and Gram-negative bacteria in 20%. Sepsis due to Staphylococcus aureus was associated with vascular and joint devices whereas Pseudomonas aeruginosa and Gram-negative rods were more common with genitourinary devices and lymphoproliferative disease. Sepsis-associated organ dysfunction most commonly involved the respiratory system, followed by the renal and circulatory systems. These patterns may provide useful clues to the pathogenesis and therapy of this often fatal syndrome which is a major ongoing problem for hospitalized patients.

The incidence of intracranial haemorrhage (ICH) in newborns with haemophilia is unknown. Retrospective studies, estimate the incidence to be around 3%. Because of this uncertainty, we analysed the largest inpatient database in the USA, the Nationwide Inpatient Sample (NIS), to better approximate the incidence of ICH in these patients. ICD-9 coding data were used to reference NIS entries of haemophilia (A, B or C) or von Willebrand's disease (VWD), with intraventricular (IVH), subarachnoid (SAH), subdural (SDH) and/or intraparenchymal (IPH) haemorrhage. Of 9.2 x 10(7) hospitalizations from 1988 to 2001, 11% or 1 x 10(7) were newborns. Of these, 0.00527%, or 580 were diagnosed with haemophilia or VWD. Twenty of 580, or 3.4%, experienced an ICH. The ICH rate in non-haemophilic newborns was 0.11% (P value: <0.0001). The rate of ICH among term haemophilic newborns without sepsis, respiratory distress syndrome (RDS) or congenital heart disease (CHD), delivered without vacuum assist was 1.9%. One death occurred on the day of birth in a term neonate with haemophilia C. The mean length of stay for ICH patients with haemophilia was 28 days (median 28, range: 6-143 days). The mean hospital charges for the group were 102,072 dollars (median 67,551 dollars, range: 9624-467,132 dollars). These data add credence to the estimates of ICH in haemophilic newborns and may guide treatment strategies around the time of their birth. Further, uncomplicated delivery of term, otherwise healthy haemophilic newborns may carry a lesser risk of ICH.

The aim of this study was to provide a broad characterization of the epidemiology of acute renal failure (ARF) in the United States using national administrative data and describe its impact on hospital length of stay (LOS), patient disposition, and adverse outcomes. Using the 2001 National Hospital Discharge Survey, a nationally representative sample of discharges from nonfederal acute care hospitals in the United States, new cases of ARF were obtained from hospital discharge records coded according to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Multivariate regression analyses were used to explore the relation of ARF to hospital LOS and mortality as well as discharge disposition. Review of discharge data on a projected total of 29,039,599 hospitalizations identified 558,032 cases of ARF, with a frequency of 19.2 per 1000 hospitalizations. ARF was more commonly coded for in older patients; men; black individuals; and the setting of chronic kidney disease, congestive heart failure, chronic lung disease, sepsis, and cardiac surgery. ARF was associated with an adjusted prolongation of hospital LOS by 2 d (P < 0.001) and an adjusted odds ratio of 4.1 for hospital mortality and of 2.0 for discharge to short- or long-term care facilities. In a US representative sample of hospitalized patients, the presence of an ICD-9-CM code for ARF in discharge records is associated with prolonged LOS, increased mortality, and, among survivors, a greater requirement for posthospitalization care. These findings suggest that in the United States, ARF is associated with increased in-hospital and post-hospitalization resource utilization.

A range of complications of pregnancy, abnormal fetal growth and development, and complications of delivery have been associated with increased risk of schizophrenia. Few studies have been able to adjust for a broad range of potential confounding factors. A national population nested case-control study based on Danish longitudinal registers was conducted to investigate the risk of schizophrenia associated with exposure to a range of obstetric events. The sample included 1039 first admissions to, or contacts with Danish psychiatric services with an ICD-8 or ICD-10 diagnosis of schizophrenia and 24, 826 individually matched controls. Adjusting for the other obstetric factors, family psychiatric history, and socio-economic and demographic factors, risk of schizophrenia was associated with maternal non-attendance at antenatal appointments (Incidence Rate Ratio (IRR) 2.08, 95% CI: 1.0, 4.4), gestational age of 37 weeks or below (IRR 1.51, 95% CI: 1.0, 2.2), maternal influenza (IRR 8.2, 95% CI: 1.4, 48.8), preeclampsia (IRR 2.72, 95% CI: 1.0, 7.3), threatened premature delivery (IRR 2.39, 95% CI: 1.4, 4.1), haemorrhage during delivery (IRR 2.43, 95% CI: 1.1, 5.6), manual extraction of the baby (IRR 2.15, 95% CI: 1.1, 4.4), and maternal sepsis of childbirth and the puerperium (IRR 2.91, 95% CI: 1.1, 7.9). There was no significant interaction between the obstetric factors and either sex or family psychiatric history. The data suggest a modest association between prematurity, indicators of hypoxia, maternal infections, and maternal behaviours and risk of the later development of schizophrenia after adjusting for a number of possible confounding factors.
