e19056 Background: Erlotinib was approved in Dec 2007 in Japan, and incidence and pattern of ILD during its therapy for Japanese pts with NSCLC has not still been determined, although we had previously reported the frequency of ILD through the gefitinib treatment [PASCO2004, #7063]. In this study, we intended to elucidate this issue in pts receiving erlotinib therapy. Methods: We reviewed the clinical records of 159 pts who had initiated erlotinib therapy last year (cohort A), and of 330 pts receiving gefitinib between 2000 and 2003 (cohort B) for comparing the incidence and pattern of ILD during the both TKI treatments. Toxicity data during the first months after the initiation of TKIs were obtained. Results: The demographics of 489 pts were as follows; M:63%, Ad:75%, and PS 0–1:69%. None of pts in the cohort B received erlotinib therapy before the gefitinib treatment, whereas 66 of the 159 cohort A pts (42%) were given gefitinib before the erlotinib therapy. In 23% and 28% of the pts in the cohorts A and B, erlotinib and gefitinb treatments were discontinued within 1 month after the initiation of TKI therapy, respectively. Two pts (1.3%) developed ILD in the cohort A during the first month of erlotinib treatment, while 8 ILD-events (2.4%) were observed in the gefitinib therapy (cohort B) during the same treatment period. Both 2 pts who developed ILD during the erlotinib therapy had not had a history of prior gefitinib treatment. The toxicity grades of ILD were as follows: grades 1 and 2 in 1 each (cohort A) and grades 3, 4 and 5 in 1, 1 and 6 pts, respectively (cohort B). Statistically significant factors affecting the occurrence of ILD by multivariate analysis were presence of prior pulmonary fibrosis (OR=37.3, p<0.01) and poor PS (OR=6.4, p=0.02), but type of TKIs was not a significant risk factor for ILD. Conclusions: In this setting, the type of TKIs did not affect the incidence of ILD although its incidence after the initiation of erlotinib was somewhat low as compared with that during gefitinib therapy. In addition, the grade of ILD was less severe in the cohort A. These might be partly due to a patient selection based on the recent awareness of Japanese physicians regarding the risk factors for ILD events who learned it through the gefitinib treatment. No significant financial relationships to disclose.

Abstract Background Silent infarcts are associated with impaired cognitive functioning and have been shown to be predictors of stroke (Miller ST J Pediatr 2001). Until now, reported risk factors for silent infarcts were low pain event rate, history of seizures, high leukocyte count and Sen bS haplotype (Kinney TR Pediatrics 1999). Here, we seek to define the prevalence and risk factors of silent infarcts in the Créteil SCA pediatric cohort comprising patients assessed at least yearly by transcranial doppler (TCD) since 1992, and by MRI/MRA. Methods This study retrospectively analyzed data from the Créteil cohort stroke-free SS/Sb0 children (280; 134 F, 146 M), according to institutional review board. Time-averaged mean of maximum velocities higher than 200 cm/sec were considered as abnormal, resulting in initiation of a transfusion program (TP). A switch to hydroxyurea was proposed to patients with normalized velocities (&lt; 170 cm/sec) and normal MRA on TP, although TP was re-initiated in case of abnormal velocities recurrence. Patients with “conditional” velocities (170–199 cm/sec) were assessed by TCD 4 times yearly. Alpha genes and beta-globin haplotypes were determined. Baseline biological parameters (G6PD activity; WBC, PMN, Reticulocytes, Platelets counts; Hemoglobin, Hematocrit, HbF, LDH levels; MCV; SpO2) were obtained a minimum of 3 months away from a transfusion, one month from a painful episode, after 12 months of age, before the first TCD, and always before therapy intensification. Results. Patients were followed for a total of 2139 patient-years. Alpha-Thal was present in 114/254 patients (45%) and 27/241 (11.2%) had G6PD deficiency. Beta genotype, available in 240 patients, was BaBa in 102 (42.5%), BeBe in 54 (22.5%), SeSe in 19 (7.9%) and “other” in 65 (27.1%); TCD was abnormal in 52 of 280 patients (18.6%). MRA showed stenoses in 30 of 226 evaluated patients (13.3%) while MRI demonstrated presence of silent infarcts in 81/280 patients (28.9%). Abnormal TCD (p&lt;0.001), G6PD deficiency (p=0.008), high LDH (p=0.03), and low Hb (p=0.026) were significant risk factors for stenoses by univariate analysis while multivariate analysis retained only abnormal TCD as a significant risk factor for stenoses ([OR= 10.6, 95% CI (4.6–24.4)]; p&lt;0.001). Univariate logistic regression analysis showed that the risk of silent infarcts was not related to alpha-Thal, beta genotype, abnormal TCD, WBC, PMN, platelets, reticulocyte counts, MCV, LDH level, HbF %, pain or ACS rates but was significantly associated with stenoses detected by MRA (p&lt;0.001), gender (male; p=0.04), G6PD deficiency (p=0.05), low Hb (p=0.016) and Hct (p=0.012). Multivariate logistic regression analysis showed that gender ([OR= 2.1, 95% CI (1.03–4.27)]; p=0.042), low Hb ([OR= 1.4, 95% CI (1.0–1.1)]; p=0.05) and stenoses ([OR= 4.8, 95% CI (1.88–12.28)]; p=0.001) were all significant independent risk factors for silent infarcts. The presence of stenoses was the only significant risk factor for silent infarcts in patients with a history of abnormal TCD ([OR= 5.9, 95% CI (1.6–21.7)]; p=0.008). Conclusion We recently showed that G6PD deficiency, absence of alpha-Thal, and hemolysis are independent significant risk factors for abnormal TCD in stroke-free SCA patients (Bernaudin et al, Blood, 2008, in press). Here, we report that an abnormal TCD is the most significant risk factor for stenoses and, expanding previous studies, we demonstrate that stenoses, low Hb and gender are significant independent risk factors for silent infarcts.

Object. The authors conducted a study to investigate the long-term natural history of unruptured intracranial aneurysms and the predictive risk factors determining subsequent rupture in a patient population in which surgical selection of cases was not performed.Methods. One hundred forty-two patients with 181 unruptured aneurysms were followed from the 1950s until death or the occurrence of subarachnoid hemorrhage or until the years 1997 to 1998. The annual and cumulative incidence of aneurysm rupture as well as several potential risk factors predictive of rupture were studied using life-table analyses and Cox's proportional hazards regression models including time-dependent covariates.The median follow-up time was 19.7 years (range 0.8–38.9 years). During 2575 person-years of follow up, there were 33 first-time episodes of hemorrhage from previously unruptured aneurysms, for an average annual incidence of 1.3%. In 17 patients, hemorrhage led to death. The cumulative rate of bleeding was 10.5% at 10 years, 23% at 20 years, and 30.3% at 30 years after diagnosis. The diameter of the unruptured aneurysm (relative risk [RR] 1.11 per mm in diameter, 95% confidence interval [CI] 1–1.23, p = 0.05) and patient age at diagnosis inversely (RR 0.97 per year, 95% CI 0.93–1, p = 0.05) were significant independent predictors for a subsequent aneurysm rupture after adjustment for sex, hypertension, and aneurysm group. Active smoking status at the time of diagnosis was a significant risk factor for aneurysm rupture (RR 1.46, 95% CI 1.04–2.06, p = 0.033) after adjustment for size of the aneurysm, patient age, sex, presence of hypertension, and aneurysm group. Active smoking status as a time-dependent covariate was an even more significant risk factor for aneurysm rupture (adjusted RR 3.04, 95% CI 1.21–7.66, p = 0.02).Conclusions. Cigarette smoking, size of the unruptured intracranial aneurysm, and age, inversely, are important factors determining risk for subsequent aneurysm rupture. The authors conclude that such unruptured aneurysms should be surgically treated regardless of their size and of a patient's smoking status, especially in young and middle-aged adults, if this is technically possible and if the patient's concurrent diseases are not contraindications. Cessation of smoking may also be a good alternative to surgery in older patients with small-sized aneurysms.

Jailinmates may be at increased risk of contracting tuberculosis [TB]. We studied 386 detainees [mean age 17.7 years] in Karachi juvenile jail to determine the prevalence of TB and possible risk factors for contracting TB. We found a 3.9% prevalence of TB among the inmates, significantly higher than the estimated 1.1% prevalence in the general population of Pakistan. Positive family history of TB was a significant risk factor for TB. Poor adherence of previously diagnosed patients to anti-TB treatment was found. Our study highlights the vulnerability of inmates to TB owing to the presence of highly infectious cases, along with environmental conditions such as overcrowding and poor ventilation. This study strongly indicates the need for an effective treatment programme in the jails as well in the general community

AbstractThe vascular complications have been a major cause of morbidity and mortality among all subtypes of BCR-ABL1 negative myeloproliferative neoplasms (MPN), but the ethnicity-specific data was limited. We therefore conducted a multi-center retrospective, longitudinal cohort study to evaluate the incidence, characteristics and risk factors of thromboembolic events of MPN patients. Of 256 patients, 27.3% experienced thromboembolic events, majority of which occurred before or within 12 months of MPN diagnosis. The multivariable Cox proportional analyses identified leukocytosis (HR 2.67, 95% CI 1.36–5.24, q = 0.004) and history of thrombosis (HR 9.68, 95% CI 2.00–46.88, q = 0.005) as the risk factors for thromboembolism. In subgroup analysis of polycythemia vera and hemoglobin concentration (HR 1.97, 95% CI 1.28–3.04, q = 0.002) appeared to be a significant risk factor of thrombosis, along with age and thrombosis history. In essential thrombocythemia, severity of the established IPSET score was closely correlated with the frequency of thromboembolic events. In primary myelofibrosis, history of thrombosis was associated with thrombosis events (HR 13.85, 95% CI 1.2–159.5, q = 0.035). Overall survival was worse in patients who experienced thromboembolic events. Our study highlighted the importance of recognizing high risk patients and implementing personalized intervention.

Aim. To study the incidence and possible risk factors for atrial fibrillation (AF) in the early postoperative period after transapical implantation of the first domestic aortic valve (TAVI) “MedLab-CT”.Material and methods. The study included 118 patients after successful TAVI. The study did not include patients with open aortic valve replacement due to dislocation of the prosthesis, with severe intraoperative complications leading to the death of the patient, and patients with permanent AF. The mean age of the patients was 71.1 ± 4.9 years, body mass index was 31.1 ± 5.9 kg/m2, men were 39.8%, hypertension was in 93.2%, diabetes mellitus (DM) was in 27.9%, paroxysmal AF was in 12.7%, coronary heart disease (CHD) was in 56.7%, smoking was noted in 8.4% cases. The median follow-up time corresponded to the hospital stay - 9.5 days. To identify cardiac arrhythmias, daily regular ECG recordings in 12 leads were assessed from the first day after TAVI. In the presence of palpitations, 24-hour ECG monitoring was performed. Indicators such as age, male gender, DM, history of AF, interatrial block before surgery, CHD, and echocardiographic parameters were studied as possible predictors of AF development in the early postoperative period after TAVI. There were no significant differences in the studied parameters in patients with AF paroxysms and sinus rhythm.Results. In the early postoperative period, AF episodess occurred in 46 (39%) patients. New-onset AF occurred in 38 (32.2%) patients. The only statistically significant risk factor for AF in the postoperative period in our series of observations was CHD (OR 5.756; 95% CI 1.009-8.132; p = 0.048).Conclusion. Patients with paroxysmal AF in the early postoperative period were not detected cerebrovascular events. In the early postoperative period, the only significant predictor of AF was the presence of proven CHD in patients.

Background Data suggesting history of direct or indirect contactto cats are either protective, has no effect or increase risk ofsensitization and asthma development.Objective To determine the relationship between childhoodcontact to cat and the development of asthma in children.Methods A case control study was conducted in Denpasar sinceDecember 2006 until Juli 2008. In this study, subjects withasthma (cases group) were selected for comparisons to a series of healthy subjects without asthma (controls group). Forty-sevensubjects (3-12 years) with asthma were recruited and matched(age and sex) with 4 7 healthy and non asthma controls. Data were collected using two kinds of questionnaires, i.e: ISAAC, ATS 78, and Robertson modification questionnaire from Medical School, University of Indonesia, which had been validated to determine asthma and asthma risk factors questionnaire. Data were analyzed as univariate by using chi-square or Fisher's exact test, and multivariate analysis by stepwise logistic regression model.Results Result of univariate analysis showed that there were seven significant risk factors of asthma. Using multivariate analysis, contact to cat was significant risk factor for asthma [OR: 4.5 (95% CI 1.3 to 16.0), P= 0.020]. Other significant risk factors were; contact to cockroach [OR: 11.7 (95% CI 2.6 to 51.6), P= 0.001], use of kapok mattress [OR: 6.4 (95% CI 1.4 to 29.0), P= 0.015], passive smoker [OR: 4.7 (95% CI 1.3 to 17.0), P= 0.018], and atopic history [OR: 9.2 (95% CI 2.3 to 36.7), P= 0.002].Conclusions There was a relationship between childhood contactto cat and the development of asthma in children. Risk factors that statistically significant were; contact to cockroach, use of kapok mattress, passive smoker, and history of allergy in study subject.

The impact of migraine on postoperative nausea and vomiting (PONV) is controversial, and few studies have focused on their relationship. Thus, we investigated the impact of migraine, among other risk factors, on PONV in a large retrospective study. We analyzed 10 years of clinical data from the Smart Clinical Data Warehouse of Hallym University Medical Center. PONV was defined as nausea or vomiting within the first 24 h after surgery. Patients diagnosed by a neurologist and with a history of triptan use before surgery were enrolled into the migraine group. We enrolled 208,029 patients aged > 18 years who underwent general anesthesia (GA), among whom 19,786 developed PONV within 24 h after GA and 1982 had migraine. Before propensity score matching, the unadjusted and fully adjusted odds ratios (ORs) for PONV in subjects with versus without migraine were 1.52 (95% confidence interval (CI), 1.34–1.72; p < 0.001) and 1.37 (95% CI, 1.21–1.56; p < 0.001), respectively. The OR for PONV in patients with migraine was also high (OR, 1.37; 95% CI, 1.13–1.66; p = 0.001) after matching. Our findings suggest that migraine is a significant risk factor for PONV.

Despite the importance of dry eye disease (DED) treatment, the rate of DED treatment discontinuation, especially discontinuation of ophthalmic follow-up, remains unknown. This study aimed to assess the prevalence and risk factors of ophthalmic follow-up discontinuation for DED. A cross-sectional survey of 1030 participants was conducted using a self-administered web-survey instrument. We collected lifestyle information, history of DED diagnosis, types of treatment, frequency of eye-drop usage, symptoms, and the reasons for discontinuing treatment. Statistical analyses including logistic regression were used to evaluate the risk factors of discontinuing ophthalmic follow-up for DED. A past history of clinical DED diagnosis was reported by 155 (15.0%) subjects. Of those, 130 had persistent DED, and 88 (67.7%) of the subjects reported discontinuation of ophthalmic follow-up for DED. The most prevalent reasons for ophthalmic follow-up discontinuation were time restrictions, followed by dissatisfaction with the DED treatment. Duration after DED diagnosis was the only significant risk factor for discontinuing ophthalmic follow-up after adjusting for age and sex (odds ratio = 1.09, 95% confidence interval = 1.02–1.17, p = 0.009). In conclusion, longer DED duration after diagnosis was a significant risk factor for discontinuing ophthalmic follow-up for DED. This study showed that DED ophthalmic follow-up discontinuation involves both medical and non-medical reasons. Clinicians need to be aware of them, and preventative effort is needed to avoid discontinuation.

Introduction: Congenital heart disease is the most common congenital problem that accounts for up to 25% of all congenital malformations. Hence this study was aimed at improving the knowledge related to risk factors associated with CHD in a rural Indian scenario. It was a hospital- based case control study. Materials and Methods: The children up to twelve year of age with clinical suspicion of CHD were subjected to chest x-ray and electrocardiography, and final diagnosis was confirmed by echocardiography (n=209) as cases. The control group (n=418) were randomly selected from children without CHD who were admitted during the same period. The etiological factors like environmental, infections, drugs, and maternal factors were analyzed by using EPI 6 version. Results: In cases group, 56% were male and 44% female children. 82% cases presented at age of less than 5 years and 18% after 5 year. Exposure to smoking (OR=10.45), tobacco intake by mother (OR=8.28) and family history of CHD (OR=7.21) were the significant risk factor present in cases. Conclusion: The risk factors for CHD child identified were exposure to smoking and tobacco intake by mother, family history of CHD, antenatal infection in 1st trimester and history of diabetic mother.
