Abstract BACKGROUND. Polymorphisms for genes encoding chemosensitive signalling proteins like NOS2 might contribute to the variability in individual susceptibility to nasal polyposis. NO produced by the inducible NO synthase enzyme NOS2A is generated at high levels in certain types of inflammation, so that the role of NOS2 might also be important in nasal polyposis etiopathogeny. MATERIAL AND METHODS. This is a cross-sectional, randomized, case-control study for the evaluation of the frequency of -954G/C NOS2A2 alleles among patients with nasal polyposis. The study included 91 cases of nasal polyposis diagnosed patients (nasal endoscopy and CT scan examination), and 117 healthy unrelated controls. NOS2 genotyping was carried out using PCR amplification of relevant gene fragment and it was followed by restriction enzyme digestion. Detection of the variant alleles was determined through analysis of resulting restriction fragment length polymorphism (RFLP) followed by gel electrophoresis. RESULTS. Molecular analysis revealed an increased frequency of NOS2 variant allele in the study group compared to the control group (p=0.019, OR=1.991, CI=1.08-3.67). A statistically significant finding was highlighted among allergic and nonallergic patients with nasal polyposis (p=0.046, OR=0.449. CI=0.208-0.969) and a relationship between nasal polyposis patients with asthma and non-asthmatic patients (p=0.119, OR=1.825, CI=0.875-3.80). CONCLUSION. The main finding of our study is that -954G/C polymorphism of NOS gene seems to be associated with an increased risk for nasal polyposis.

Background: In this study our main goal was to evaluate the association of psoriasis as a risk predictor for the occurrence of diabetes mellitus (DM) and hypertension (HTN).Methods: This case control study was carried out in the department of dermatology and venereology, Chittagong medical college hospital (CMCH), Chittagong, Bangladesh from 15 June 2011 to 14 May 2012. Where 60 patients with psoriasis and 60 patients with skin diseases other than psoriasis were included according to availability within the study period.Results: During study, among the psoriatic patients, most of the patients with DM and HTN had body mass index (BMI) within normal limit. During analysis of different clinical findings in psoriatic patients scaling was present in all the cases followed by Auspitz sign, koebnerization, itching, scalp involvement and nail changes. Patients with psoriasis were found to have higher incidence of DM and HTN in comparison to their non-psoriatic control group. It was also observed that psoriatic patients having DM and HTN had longer duration of diseases (p<0.05).Conclusions: In conclusion, our study indicates that patients with psoriasis have an increased risk of DM and HTN, confirming the findings from previous several case control and cross sectional studies. These data illustrate the importance of considering psoriasis as a systemic disorder rather than simply a skin disease. Awareness of concurrent diseases will provide the clinician an opportunity of screening .for others systemic diseases.

Abstract Background Maintenance immunosuppressive regimens after renal transplantation (RTx) most often include prednisolone, which may induce secondary adrenal insufficiency, a potentially life-threatening side effect to glucocorticoid (GC) treatment due to the risk of acute adrenal crisis. We investigated the prevalence of prednisolone-induced adrenal insufficiency in RTx patients receiving long-term low-dose prednisolone treatment. Methods We performed a case–control study of patients on renal replacement therapy differing in terms of GC exposure. The study included 30 RTx patients transplanted &gt;11 months before enrolment in the study and treated with prednisolone (5 or 7.5 mg prednisolone/day for ≥6 months) and 30 dialysis patients not treated with prednisolone. Patients underwent testing for adrenal insufficiency by a 250-µg Synacthen test performed fasting in the morning after a 48-h prednisolone pause. Normal adrenal function was defined as P-cortisol ≥420 nmol/L 30 min after Synacthen injection. This cut-off is used routinely for the new Roche Elecsys Cortisol II assay and is validated locally based on the Synacthen test responses in 100 healthy individuals. Results Thirteen RTx patients {43% [95% confidence interval (CI) 27–61]} had an insufficient response to the Synacthen test compared with one patient in the control group [3% (95% CI 0.6–17)] (P = 0.0004). Insufficient responses were seen in 9/25 and 4/5 RTx patients treated with 5 and 7.5 mg prednisolone/day, respectively. Conclusions We found a high prevalence of adrenal insufficiency among RTx patients receiving low-dose prednisolone treatment. We therefore advocate for increased clinical alertness towards prednisolone-induced adrenal insufficiency in RTx patients and thus their potential need of rescue GC supplementation during stress.

Abstract Objective In this study, our aim was to investigate the clinical significance of VEGF, sVEGFR-1 in HFpEF patients. Materials and methods Seventy-two participants enrolled in this cross-sectional case-control study including HFpEF patients (n=41) and healthy (n=31) subjects. Blood samples were collected and serum VEGF, sVEGFR-1 analysis, and transthoracic echocardiography were performed. Results and discussion The average sVEGFR-1 level of HFpEF patient group was significantly higher than the control group (respectively 0.136 ng/L (0.04–0.34), 0.06 ng/L (0.01–0.25); p<0.001). The average VEGF level of HFpEF patients using beta blocker was significantly higher than the HFpEF patients not using it (respectively 0.585±0.194 ng/L; 0.349±0.269 ng/L; p=0.025). The average VEGF level of HFpEF patients using statins was significantly higher than the HFpEF patients without a medication (respectively 0.607±0.099 ng/L; 0.359±0.273 ng/L; p=0.038). Conclusion Our study is the first study demonstrating the relations among HFpEF, accompanying morbidities, VEGF and sVEGFR-1 levels. Statins and beta blockers may have positive effects on angiogenesis in HFrEF patients via increasing VEGF levels.

Our objective was to estimate the effect of therapeutic hypothermia on platelet count in neonates after perinatal asphyxia. We performed a retrospective case control study of all (near-) term neonates with perinatal asphyxia admitted between 2004 and 2012 to our neonatal intensive care unit. All neonates treated with therapeutic hypothermia were included in this study (hypothermia group) and compared with a historic control group of neonates with perinatal asphyxia treated before introduction of therapeutic hypothermia (2008). Primary outcome was thrombocytopenia during the first week after birth. Thrombocytopenia was found significantly more often in the hypothermia group than in the control group, 80% (43/54) versus 59% (27/46) (P=.02). The lowest mean platelet count in the hypothermia group and control group was97×109/Land125×109/L(P=.06), respectively, and was reached at a mean age of 4.1 days in the hypothermia group and 2.9 days in the control group (P<.001). The incidence of moderate/severe cerebral hemorrhage was 6% (3/47) in the hypothermia group versus 9% (3/35) in the control group (P=.64). In conclusion, neonates with perinatal asphyxia treated with therapeutic hypothermia are at increased risk of thrombocytopenia, without increased risk of cerebral hemorrhage.

Abstract Objective The objective of this cross-sectional case-control study was to determine the prevalence and size of marginal and subarticular osteophytes in patients with osteoarthritis (OA), and to compare these to that of a control group. Design We investigated femoral heads from 25 patients with OA following hip replacement surgery, and 25 femoral heads from a control group obtained post-mortem . The area and boundary length of the femoral head, marginal osteophytes, and subarticular osteophytes were determined with histomorphometry. Marginal osteophytes were defined histologically as bony projections at the peripheral margin of the femoral head, while subarticular osteophytes were defined as areas of bone that expanded from the normal curvature of the femoral head into the articular cartilage. Results The prevalence of OA patients with marginal- and subarticular osteophytes were 100% and 84%, respectively. Whereas the prevalence of the participants in the control group with marginal- and subarticular osteophytes were 56% and 28%, respectively. The area and boundary length of marginal osteophytes was (median (Interquartile range)) 165.3mm 2 (121.4 – 254.0) mm 2 and 75.1 mm (50.8 – 99.3) mm for patients with OA compared to 0 mm 2 (0 – 0.5) mm 2 and 0 mm (0 – 0.5) mm for the control group (P < 0.001). For the subarticular osteophytes, the area and boundary length was 1.0 mm 2 (0 – 4.4) mm 2 and 1.4 mm (0 – 6.5) mm for patients with OA compared to 0 mm 2 (0 – 0.5) mm 2 and 0 mm (0 – 0.5) mm for the control group (P < 0.001). Conclusion As expected, both marginal- and subarticular osteophytes at the femoral head, were more frequent and larger in patients with OA than in the control group. However, in the control group, subarticular osteophytes were more prevalent than expected from the minor osteophytic changes at the femoral head margin, which may suggest that subarticular osteophytes are an early degenerative phenomenon that ultimately might develop into clinical osteoarthritis.

Opium Use

Abstract Background: In recent years, lung cancer (LC) incidence has increased in Iran. The use of opium and its derivatives (O&D) has increased as well. This study aimed to investigate the association between the use of O&D and LC incidence.Methods: In this case-control study conducted in Kerman, Iran; 140 patients with lung cancer and 280 healthy controls matched by age, sex, and place of residence were included. Data, including O&D use, cigarette smoking, alcohol use, and diet, were collected using a structured questionnaire. The relation between the use of O&D and LC was evaluated using conditional logistic regression adjusted for tobacco smoking, education, daily intake of fruit, vegetables, red meat, and hydrogenated fats.Results: Opium ever-use was associated with an increased risk of LC (Adjusted Odds Ratio (AOR) =5.95, 95 % CI: 1.87 -18.92). Participants were divided into low and high use groups based on the median of opium use in the control group. A significant dose-response relation was observed between the amount of daily O&D use and LC; and the relation was stronger in high users (AOR low users = 3.81 % CI: 1.13 -12.77 and OR high users= 9.36, 95% CI: 2.05 -42.72). Also, LC was higher among participants starting the use of O&D at younger ages (≤ 41 years old vs never users AOR = 8.64, 95 % CI: 1.90 -39.18) compared to those who started at an older age ( >41 years old vs never users, AOR = 4.71, 95 % CI: 1.38 - 16.08). The association between opium, and lung cancer among non-smokers was OR: 6.50 (95% CI: 2.89 to 14.64).Conclusion: The results of this study show that opium use is probably a dose related risk factor for lung cancer.

BackgroundThe association of complications of pregnancy and the risk of developing gynecological cancer is controversial with the limited study. In this study, we investigated the association of preeclampsia, or gestational diabetes mellitus (GDM), or large for gestational age (LGA), or intrauterine growth restriction (IUGR) and the risk of endometrial or ovarian cancer.MethodsIn this case-control study, 189 women with endometrial cancer and 119 women with ovarian cancer were included. 342 women without gynecological cancers were randomly selected as a control group. Data on the history of pregnancy and age at diagnosis of gynecological cancer as well as the use of intrauterine devices (IUDs) were collected.ResultsWomen with a history of preeclampsia or IUGR did not have an increased risk of developing endometrial or ovarian cancer. While women with a history of GDM or with the delivery of LGA infant increased the risk of developing endometrial cancer but not ovarian cancer. The odds of women with a history of GDM or with the delivery of LGA infant developing endometrial cancer was 2.691 (95% CI: 1.548, 4.3635, p=0.0003), or 6.383 (95% CI: 2.812, 13.68, p&lt;0.0001) respectively, compared to the controls. The odds ratio of women who did not use IUDs developing ovarian cancer was 1.606 (95% CI: 1.057, 2.434), compared to the controls. There was no association of age at first birth and developing endometrial or ovarian cancer.ConclusionOur observational data suggested that GDM and delivery of an LGA infant are associated with an increased risk of endometrial cancer.

Abstract BackgroundOvert hyperthyroidism and hypothyroidism are associated with pregnancy complications; however, most women with these conditions are diagnosed before conception and are under treatment during pregnancy, especially in the developed countries. The purpose of this study was to investigate pregnancy complications among these women.MethodsA retrospective case-control study was conducted, and data on 3824 pregnant women who gave birth at Nagoya University Hospital located in Japan from 2005 to 2014 was collected. The pregnancy outcomes were divided and compared among three groups: the control group (n = 3709), the hyperthyroidism group (n = 52) and the hypothyroidism group (n = 63). Risk factors for placental abruption were also evaluated in singleton pregnancies (n = 3588) by multivariable logistic regression analysis. Moreover, in hyperthyroidism, thyroid function was also compared between successful and failed placentation group, and the latter group included placental abruption and preeclampsia. ResultsThe incidence of placental abruption was significantly higher in hyperthyroidism than in control and hypothyroidism groups (p < 0.01). Hyperthyroidism was independently associated with an increased risk of placental abruption (adjusted odds ratio = 12.52, 95% confidence interval = 2.91–53.88). Thyroid stimulating hormone (TSH) was significantly lower in failed placentation group than in successful placentation group (p < 0.05). ConclusionAccording to the results of our study, pregnancy outcomes in women with treated hypothyroidism were comparable with those in women without thyroid disease. Conversely, women with treated hyperthyroidism showed an independent risk of placental abruption, which might be related with lower TSH level at early gestation. However, further research is required to validate our findings.

AbstractEpidemiological studies have demonstrated an increased risk of non-Hodgkin lymphoma (NHL) in patients with chronic hepatitis C virus (HCV) infection. Therefore, we investigated the risk of extrahepatic malignancies associated with HCV infection. Inpatients diagnosed with lymphoma, breast, thyroid, kidney, or pancreatic cancer (research group, n = 17,925) as well as inpatients with no malignancies (control group, n = 16,580) matched by gender and age were enrolled from The First Affiliated Hospital of Nanjing Medical University between January 2008 and December 2016. A case-control study was conducted by retrospective analysis. The difference in HCV prevalence was analyzed between the research group and the control group. Also, the research group was compared to the 2006 National Hepatitis C sero-survey in China. A total of 86 cases were positive for anti-HCV in the research group. Compared with the control group (103 cases were anti-HCV positive), no significant associations between extrahepatic malignancies and HCV infection were observed. Meanwhile, compared to the 2006 National Hepatitis C sero-survey, we observed a significant association between the chronic lymphoma leukemia/small lymphocytic lymphoma (CLL/SLL) and HCV seropositivity in females in the research group aged 1–59 years old (OR = 14.69; 95% CI, 1.94–111.01). HCV infection had a potential association with CLL/SLL in females aged 1–59 years old. Our study did not confirm an association between HCV infection and the risk of extrahepatic malignancies. In regions with a low HCV prevalence, the association between HCV infection and extrahepatic malignancies needs further investigation.
