Abstract Background Progressive myelomalacia (PMM) is a usually fatal complication of acute intervertebral disc extrusion (IVDE) in dogs but its risk factors are poorly understood. The objective of this retrospective case-control study was to identify risk factors for PMM by comparing dogs with complete sensorimotor loss following IVDE that did and did not develop the disease after surgery. We also investigated whether any risk factors for PMM influenced return of ambulation. Medical records of client-owned dogs with paraplegia and loss of pain perception that underwent surgery for IVDE from 1998 to 2016, were reviewed. Dogs were categorized as PMM yes or no based on clinical progression or histopathology. Walking outcome at 6 months was established. Signalment, onset and duration of signs (categorized), steroids, non-steroidal anti-inflammatory drugs (yes or no), site of IVDE (lumbar intumescence or thoracolumbar) and longitudinal extent of IVDE were retrieved and their associations with PMM and walking outcome were examined using logistic regression. Results One hundred and ninety seven dogs were included, 45 with and 152 without PMM. A 6-month-outcome was available in 178 dogs (all 45 PMM dogs and 133 control dogs); 86 recovered walking (all in the control group). Disc extrusions at the lumbar intumescence were associated with PMM (p = 0.01, OR: 3.02, CI: 1.3–7.2). Surgery performed more than 12 h after loss of ambulation was associated with PMM (OR = 3.4; CI = 1.1–10.5, p = 0.03 for 12-24 h and OR = 4.6; CI = 1.3–16.6, p = 0.02 for the > 24 h categories when compared with the ≤12 h category). Treatment with corticosteroids was negatively associated with PMM (OR: 3.1; CI: 1.3–7.6, p = 0.01). The only variable to affect walking outcome was longitudinal extent of IVDE (OR = 2.6; CI = 1.3–5.3, p = 0.006). Conclusion Dogs with lumbar intumescence IVDE are at increased risk of PMM. Timing of surgery and corticosteroid use warrant further investigations. PMM and recovery of walking are influenced by different factors.

Asfiksia perinatal merujuk pada kekurangan oksigen selama persalinan, sehingga berpotensi menyebabkan kematian dan kecacatan. WHO memperkirakan  4 juta anak terlahir dengan asfiksia setiap tahun, dimana 1 juta di antaranya meninggal dan 1 juta anak bertahan hidup dengan gejala sisa neurologis yang parah. Penelitian ini bertujuan untuk menganalisis faktor risiko fetal dan tali pusat pada asfiksia neonatal.Penelitian dilakukan di lakukan di RS Dr Moewardi Surakarta dengan pendekatan  quantitative retrospective case control study. Data diambil dari rekam medis antara  tahun 2013-2018. Penelitan ini melibatkan  264 neonatal yang terdiri dari 88 kelompok kasus dan 176  kelompok control. Kelompok kasus adalah bayi dengan diagnosa  asfiksia yang  dilakukan analisis terhadap faktor risiko fetal, sedangkan bayi yang tidak mengalami asfiksia dijadikan  kelompok kontrol. Hasil analisis statistik uji Chi-Square dan Fisher Exact ditemukan bahwa  kelahiran prematur (OR 2,07 CI 95% P 0,02), persalinan dengan tindakan (OR 3,61 CI 95% P 0,00), berat bayi (OR 2,85 CI 95% P 0,00), posisi janin (OR 2,37 CI 95% P 0,05), tali pusat ( QR 3,071 CI 95%  P 0,01)  berisiko terhadap insiden asfiksia perinatal. Air ketuban yang bercampur meconium (OR 1,51 CI 95% P 0,16) tidak memiliki risiko  dengan Asfiksia perinatal. Kesimpulan: Risiko terhadap insiden asfiksia perinatal  meliputi kelahiran prematur, persalinan dengan tindakan, berat bayi, posisi janin,  dan tali pusat.Perinatal asphyxia refers to a lack of oxygen during labor, which has the potential to cause death and disability. WHO estimates  4 million children born with asphyxia each year, in  which 1 million dies and 1 million survive with severe neurological sequelae. This study aims to analyze fetal and umbilical risk factors in neonatal asphyxia.This research is a quantitative retrospective case-control study, which was conducted at The Dr. Moewardi  hospital,  Surakarta. Data was taken from  medical records from 2013-2018. The case group was patients diagnosed  asphyxia, while those who did not experience asphyxia were treated as a control group.  A total of 264  samples, consisting of 88 case group respondents and 176 control group respondents. Statistical analysis Chi- Square and Fisher Exact found that preterm birth (OR 2.07 CI 95% P 0.02), labor with instrument or complication (OR 3.61 CI 95% P 0.00), infant weight (OR 2.85 CI 95% P 0, 00), fetal position (OR 2.37 CI 95% P 0.05), umbilical cord (QR 3.071 CI 95% P 0.01) are at risk for the incidence of perinatal Asphyxia. The amniotic fluid mixed with meconium (OR 1.51 CI 95% P 0.16) has no risk with perinatal asphyxia.The risk factors of incidences of perinatal asphyxia were  preterm birth, labor with instrument or complication, baby weight, fetal position and umbilical cord.

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.

Objective: To investigate the predictors of preeclampsia based on a 10-years case-control study. Materials and methods: The present retrospective, case-control study was carried out in a referral Hospital in Hamadan, Iran, during 2005-2015. Using a hospital information system (HIS), all the available information on hospitalized preeclamptic patients during 10-years period was collected and all preeclamptic women were qualified for the study as the case group (729 subjects) and the same number of non-preeclamptic women were assigned to the control group. The required data were collected using the researcher-made questionnaire and analyzed using descriptive statistics, chi-square test, independent t-test and logistic regression. Results: The results show that high age (OR = 1.04), low education (diploma compared to illiterate OR = 0.51 and middle school education compared to illiterate OR = 0.55), blood group O (AB: OR = 0.32; B: OR = 0.36; A: OR = 0.26) and fertilization during autumn (spring: OR = 0.41; summer: OR = 0.26; autumn: OR = 1.13) could raise the risk of preeclampsia. Conclusion: High age, low education, blood group O and fertilization in cold seasons could be the risk factors of preeclampsia.  Recognizing the risk factors of preeclampsia could help the determination of high risk cases and designing of effective interventions.

ObjectivesBiliary atresia (BA) is regarded as a serious neonatal hepatobiliary disease, and its aetiology and pathogenesis remain unclear. Epidemiological studies are limited, especially for the data from China. This study aims to explore risk factors of BA and provide new evidence to improve understanding of its aetiology.DesignThis is a case–control study from 1 January 2015 to 31 December 2016.SettingCases were consecutively recruited from an urban tertiary care academic children’s hospital in Shanghai, China, while the controls were recruited from a community hospital in Shanghai through a random sampling system.Participants721 patients suspected for BA who planned to take the diagnostic surgery were enrolled preoperatively. 613 were diagnosed with BA and recruited into the case group. Meanwhile, 688 infants without any observed major congenital anomalies or jaundice were enrolled. Finally, 594 valid questionnaires from the case group and 681 from the control group were obtained.Primary and secondary outcome measuresStandardised questionnaires were used for data collection. Multivariate logistic regression analysis was performed to evaluate associations reported as ORs and precision, by adjusting covariates.ResultsAnxiety or stress during pregnancy was strongly associated with increased risk of BA (OR 8.36 (95% CI: 4.08 to 17.15); p<0.001), respectively. Lower birth weight, fathers from ethnic minorities of China, older age of fathers, lower income of parents, and exposure to infection, diseases and medication during pregnancy all made differences.ConclusionsSocial factors including the educational and economic background and its related anxiety and stress during pregnancy might be noticed in the occurrence of BA. Maternal infections during pregnancy in the prevalence of BA were demonstrated.Trial registration numberChiCTR-IPR-15005885.

Background: India has seen a surge in COVID-19 associated mucormycosis (CAM) cases during the second wave of the pandemic. We conducted a study to determine independent risk factors for CAM. Methods: We performed a retrospective case control study in a tertiary care private hospital in Pune, India. Fifty-two cases of CAM were compared with 166 concurrent controls randomly selected from the COVID-19 admissions during the same time period. Association of demographic factors, comorbidities, cumulative steroid dose used (calculated as dexamethasone equivalent), maximum respiratory support required, use of injectable/oral anticoagulation, and use of aspirin with CAM was assessed by univariate and multivariate logistic regression. Results: A total of 218 subjects (52 cases; 166 controls) were studied. Any diabetes (pre-existing diabetes and new onset diabetes during COVID-19) was noted in a significantly higher proportion of cases (73.1%, 45.8% P<0.001) and cumulative dexamethasone dose used in cases was significantly greater (97.72 mg vs 60 mg; P=0.016). In a multivariate regression analysis cumulate dexamethasone dose >120 mg (OR 9.03, confidence interval 1.75-46.59, P=0.009) and any diabetes (OR 4.78, confidence interval 1.46-15.65, P=0.01) were found to be risk factors for CAM. While use of anticoagulation (OR 0.01, confidence interval 0.00-0.09, P<0.001) and use of aspirin (OR 0.02, confidence interval 0.01-0.07, P<0.001) were found to be protective against CAM. Conclusion: Diabetes mellitus and cumulative dose of dexamethasone greater than 120 mg (or equivalent dose of other corticosteroid) were associated with an increased risk of CAM while use of aspirin and anticoagulation were associated with a lower risk.

Though the incidence of gout in general population is less than 5% (globally), a study conducted in Eritrea among patients with multidrug resistant tuberculosis (MDR-TB) revealed a higher incidence (25%). Other similar studies conducted elsewhere, however, did not report gout as an adverse effect. It is unknown why a higher incidence of gout is being reported in Eritrea compared to similar studies from other countries. The objective of this study is therefore to explore risk factors for the increased risk of incident gout among MDR-TB patients in Eritrea. A case-control study was conducted in Merhano MDR-TB National Referral Hospital in Eritrea. All MDR-TB patients diagnosed with gout between June 2011 and June 2018 were considered as cases. Controls matched by age, sex, and cumulative drug exposure time were selected from the same study population (1:1 ratio). A total of 84 MDR-TB patients, 42 cases and 42 controls, were included in this study. No patient from the control group has comorbidities, while six patients from the case group have diabetes (χ2 = 6.46, df=1, p=0.026). Patients having tachycardia (OR=3.26, 95% CI=1.28, 8.27), alopecia (OR=3.11, 95% CI=1.00, 9.67), and gastrointestinal upset (OR=3.17, 95% CI=1.26, 7.96) as adverse effects and being on prolonged use of propranolol (OR=3.26, 95% CI=1.28, 8.27) were found to be more likely to develop incident gout compared to their controls. In conclusion, MDR-TB patients with diabetes mellitus, tachycardia, alopecia, and gastrointestinal upset and on prolonged use of propranolol tablet had increased risk of incident gout.

AbstractThe aim of the present case-control study was to assess the risk factors for Basal cell carcinoma (BCC) in the Montenegrin population. The study group was comprised of 100 consecutive patients with a diagnosis of BCC, while the control group consisted of patients who did not present skin cancer and who were individually matched to the cases by sex and age. The increased risk for BCC was associated with: the presence of nevi (odds ratio [OR] = 3.77; 95% confidence interval [CI] = 1.12–12.73), type of skin concerning to burn rather than to tan after repeated sun exposure in childhood or adolescence (OR = 3.14; 95% CI = 1.59–6.18), the skin reaction to burn after two or more hours of sunlight during childhood or adolescence (OR = 4.53; 95% CI = 2.37–8.63), the number of severe and painful sunburns during their lifetime(OR = 3.52; 95% CI = 1.68–7.38), outdoor work during the summer-time (OR = 2.73; 95% CI = 1.00–7.45), occupational exposure to chemicals (OR = 17.89; 95% CI = 2.82–113.52), history of eczema (OR = 4.17; 95% CI = 1.53–11.39), and history of previous BCC (OR = 3.86; 95% CI = 1.40–10.65). Our study confirms the role of environmental and constitutional factors in development of BCC.

The aim of this retrospective case-control study is to determine a possible correlation between breathing mode and craniofacial morphology. The study was carried out in the Department of Pedodontics,Iuliu Hatieganu University of Medicine and Pharmacy, Cluj-Napoca, Romania. The sample comprised 80 patients, age between 6 and 13 years, which were divided in two groups based on respiratory pattern: control group composed of 38 nasal breathing children and case group composed of 42 oral breathing children. Three quantitative craniofacial parameters were measured from the frontal and lateral photos: facial index, lower facial height ratio and upper lip ratio. The statistical analysis showed a significant higher facial index (p=0.006*) and an increase lower facial height (p=0.033*) for the oral breathers group. No differences in facial morphology were found between genders and age groups, when comparing the data between the same type of respiratory pattern children. Spearman�s rho Correlation show a significant positive correlation (p=0.002*) between facial index and lower facial height and a significant negative correlation between facial index and upper lip (p=0,005*). Long faces children are more likely to develop oral breathing in certain conditions, which subsequently have a negative effect on increasing the lower facial height by altering the postural behavior of mandible and tongue.

Abstract BACKGROUND Intraoperative prediction of postoperative cerebral hyperperfusion syndrome (CHS) after cerebrovascular bypass surgery is challenging. OBJECTIVE To conduct a retrospective case-control study with indocyanine green (ICG) intensity analysis of the superficial temporal artery-middle cerebral artery (STA-MCA) bypass and investigate whether its washout pattern might be a marker for intraoperative prediction of CHS. METHODS Between 2012 and 2018, 6 of 112 patients (5.4%) that underwent STA-MCA bypass exhibited CHS. We selected 5 patients with CHS (3 with atherosclerotic cerebrovascular disease [ASCVD] and 2 with moyamoya) and 15 patients without CHS (60% ASCVD and 40% moyamoya) as a matched control group. During prebypass and postbypass, washout times (WTs) for the first 10%, 25%, 50%, and 75% of maximum ICG intensity measured in the whole-camera field were compared between groups. The changes in WT (ΔWT) from prebypass to postbypass for each ICG intensity level were compared between groups. The cutoff ΔWTs, sensitivities, and specificities were also calculated. RESULTS Postbypass WTs were significantly longer in the CHS group than the control group at all ICG intensities (P < .05). ΔWT was significantly greater in the CHS group than the control group for the first 10%, 25%, and 50% ICG intensities (P < .001). A cutoff ΔWT of ≥2.66 s for the first 50% ICG intensity showed a sensitivity of 100% and specificity of 100%. CONCLUSION We found that a ΔWT ≥2.66 s for the first 50% ICG intensity could be an intraoperative predictive factor for CHS.

Abstract Introduction Nephrolithiasis is pathological calcification in the excretory passages of the body and is prevalent among 7.6% of Indians. We aimed to study the various risk factors associated with renal stones from India. Method It was a hospital-based case-control study conducted over 18 months in a tertiary hospital in Delhi. Cases were defined as patients with renal stones diagnosed on the basis of history and radiological examination. Controls were similar to cases in all respects except for the diagnosis and selected from the hospital. A total of 18 risk factors, including age, gender, heavy metals, stress, metabolic factors, alcohol intake, dietary habits, co-morbidities, etc. were assessed. Logistic regression analysis was performed to calculate the strength of the risk associations. Results In the analysis of 60 cases and controls, we found 6 times, 5.5 times, and 2.4 times increased odds of renal stones in patients with increased arsenic, cadmium, and lead concentrations in blood, respectively. Similarly, there are 3 times increased odds of renal stones in patients suffering from stress. Conclusions Exposure to smoke, occupation dust, and contaminated water may lead to an increased ingestion/inhalation of heavy metals like cadmium, arsenic, and predisposing people to an increased risk of renal stones.
