Abstract Introduction Leishmaniasis is a life-threatening zoonosis of which dogs are the major reservoir and sandflies are the vectors. Until now, the prevalence of canine leishmaniasis (CanL) in the Slovenian dog population was unknown. Material and Methods Epidemiological data, eye swabs and blood samples were taken from 465 dogs born in Slovenia and older than one year. Commercial ELISA kits and real-time PCR were used. For ELISA-positive samples, an immunofluorescence antibody test (IFAT) was performed. Descriptive statistics were used to characterise the samples. The one-sample nonparametric chi-square test was used to test whether the categories of a variable were equally distributed. Results A 59.9% proportion of the recruited dogs had travelled to endemic regions and 62.1% of them had not been protected by insect repellents. Skin symptoms that might be CanL-related were described in 109 of the dogs’ histories (23.4%), inappetence and/or weight loss in 25 (5.4%), and anaemia, intermittent fever, and/or lymphadenopathy in 19 (4.1%). At the time of recruitment, all dogs were asymptomatic. All samples were PCR negative, nine (1.9%) were ELISA positive, but none were IFAT positive. Five of the nine ELISA-positive dogs were non-travellers. Conclusion We conclude that the seroprevalence of canine leishmaniasis of 1.9 % in the autochthonous Slovenian dog population may pose a risk of endemic spread of the disease.

Eclampsia, a life threatening complication of pregnancy. It is one of the important cause of  maternal mortality of Bangladesh. Eclamptic seizure can effectively controlled by use of  magnesium sulphate. A prospective randomized case control study was conducted at eclampsia ward of Dhaka Medical College Hospital for one year from June 2007 to May 2008.Objective: To find out whether only 8gm of magnesium sulphate heptahydrate (Nalepsin) as a  single loading dose is sufficient to control eclamptic convulsion and also to compare the efficacy between 8gm & 10gm of MgSo4 used to control convulsion.Methodology: A random selection was done by lottery of those antepartum and intrapartum  cases who fulfill the selection criteria. Hundred patient were selected and grouped them into  case & control. 8gm Nalepsion (Magnesium sulphate heptahydrate) as a single I.V dose was  selected for case and 10gm MgSo4 (4gm I.V + 3gm I.M in each buttock) was for control  group. Different variables were compaired and results were analyzed by unpaired ‘t’ test and chi-square test (X2) by SPSS programme. Result: Statistically there was no significant difference of any finding between two groups after comparing all variables individually.Conclusion: 8gm Nalepsin intravenously as a single loading dose is sufficient to control  eclamptic convulsion and prevention of its recurrence.DOI: http://dx.doi.org/10.3329/bjog.v25i2.13743 Bangladesh J Obstet Gynaecol, 2010; Vol. 25(2) : 71-76

Objective: To assess primary molars early loss in mixed dentition prevalence. Method: A study was carried out in children aged 6 to 12 years. Deciduous molar loss was considered early when it occurred before Nolla stage 6 (full formed crown) of the permanent successor or one year before its physiological exfoliation. Periapical radiographs were obtained to verify the presence of the permanent successor and the level of root formation, as well as the need for placement of fixed space maintainer lingual arch or Nance button. For the study of frequency distribution of early dental loss in relation to gender and dentition, we used the Chi-square test of 5% probability level and the non-parametric Mann-Whitney test for adequate statistical analysis. Results: Of the 315 children examined, 159 (50.47%) were male and 156 (49.52%) were female. Only 25 (7.9%) presented multiple dental losses in the posterior region, 19 in the lower arch and 6 in the upper arch. In the inferior one there was predominance of first and second deciduous molars loss. There was no difference in the association between genders and the occurrence of multiple dental losses (χ² (1) = 0.03, p>0.05). Conclusion: The prevalence of deciduous teeth premature loss was of 7.9% and the most affected teeth were the first and second molars in the lower arch. Lingual arch space holders were installed in 6 children, who will remain with it until the permanent successors erupt into the oral cavity.

Typhoid is a life-threatening disease that has remained endemic in parts of Africa and Asia where its burden is elevated by the inefficiency of control efforts which have been hampered by lack of epidemiological data, among others. In Nigeria, such data is absent in most of the States like Gombe where the disease has been rife for a long time, hence, to bridge that knowledge gap, this study was set up to determine the host-associated risk factors for typhoid occurrence and recurrence in Gombe. A questionnaire that was designed and validated for this location was used to obtain data from 663 respondents using simple random sampling and analyzed using the Chi-square test for association and binomial logistic regression to obtain risk factors for typhoid occurrence and recurrence, respectively. The study revealed that occurrences were statistically significantly associated with the variables for vaccination (χ2 = 39.729, p < 0.01), having houseboy/girl (χ2 = 16.909, p < 0.01), typhoid patient at home (χ2 = 13.393, p < 0.01), hand washing before handling food (χ2 = 22.856, p < 0.01), consuming iced/frozen items (χ2 = 16.805, p < 0.01), boiling drinking water (χ2 = 49.633, p < 0.01), and eating commercially available foods/drinks (χ2 = 27.864, p < 0.01), while recurrences were statistically significantly predicted by „not sure of been vaccinated‟ (OR = 2.962, CI = 1.290 to 6.802, p < 0.01), „not having another typhoid patient at home‟ (OR = 1.799, CI = 0.998 to 3.244, p < 0.01), and „drinking unboiled water sometimes‟ (OR = 2.130, CI = 1.023 to 4.434, p < 0.01). It is believed that these findings will guide efforts by the Government for health interventions against typhoid in the study area, thus improving the quality of life for the population.

Introduction: Psychiatric emergencies constitute between 1% - 10% of general emergencies in Spain, of which a quarter will end up being hospital admissions. There is little literature on patients who are referred from general to specialized hospitals. Methods: Cross-Sectional study of all the patients referred in 2018. Sociodemographic variables and clinical variables, such as diagnosis and discharge destination, were analyzed. An analysis was performed by comparing means with the Chi Square test. Results: 433 derived emergencies were analyzed. Most of the patients were women. The main reason for derivation were suicide attempts. Of those patients, 40% required hospitalizations. More than 50% of the derived emergencies were referred to the home and followed up on an outpatient basis. Conclusion: Most derived emergencies are referred to the home after evaluation. This implies that most are not life-threatening and that with adequate tools for evaluating suicide risk, we could avoid transfers and improve the resolution of these cases.

Objective: Triticeous cartilage is a small ovoid structure belonging to the laryngeal skeleton. When calcified, it becomes visible on panoramic radiographs and be mistaken for a carotid artery calcification (CAC) associated with cerebrovascular accidents. This study aimed to estimate the prevalence of calcified triticeous cartilage (CTC) detected by means of digital panoramic radiographs in a sample of Lebanese population. Materials and Methods: Digital panoramic radiographs of 500 Lebanese adult patients (281 females and 219 males) with a mean age of 47.9 years were included in this study and examined for CTC. The IBM® SPSS® for Windows version 20.0 (SPSS, Chicago, IL, USA) was used to carry out statistical analysis of the data collected. Results: Nearly 10.6% (53 out of 500) of the radiographs examined presented CTC. Of all the calcifications, 11 were on the right side, 5 on the left side, and 37 were bilateral. The cases detected belonged to 31 females and 22 males with an average age of 55.6 years (ranging from 24 to 85 years). Chi-square test did not show any statistical connection between gender and CTC, while Spearman's correlation analysis showed low positive correlation with age (r = 0.146). Conclusion: CTC can be detected on panoramic radiographs taken in daily dental practice; its identification is essential to avoid misdiagnosis with other calcifications in the neck region closely related to life-threatening risks such as CAC.

Objectives The purpose of the current study was to evaluate the analytical performance of seven kits for detecting IgM/IgG antibodies against coronavirus (SARS-CoV-2) by using four chemiluminescence immunoassay systems. Methods Fifty patients diagnosed with SARS-CoV-2 infection and 130 controls without coronavirus infection from the General Hospital of Chongqing were enrolled in the current retrospective study. Four chemiluminescence immunoassay systems, including seven IgM/IgG antibody detection kits for SARS-CoV-2 (A_IgM, A_IgG, B_IgM, B_IgG, C_IgM, C_IgG and D_Ab), were employed to detect antibody concentrations. The chi-square test, the receiver operating characteristic (ROC) curve and Youden’s index were determined to verify the cut-off value of each detection system. Results The repeatability verification results of the A, B, C and D systems are all qualified. D_Ab performed best (92% sensitivity and 99.23% specificity), and B_IgM performed worse than the other systems. Except for the A_IgM and C_IgG systems, the optimal diagnostic thresholds and cut-off values of the other kits and their recommendations are inconsistent with each other. B_IgM had the worst AUC, and C_IgG had the best diagnostic accuracy. More importantly, the B_IgG system had the highest false-positive rate for testing patients with AIDS, tumours and pregnancies. The A_IgM system test showed the highest false-positive rates among elderly individuals over 90 years old. COVID-2019 IgM/IgG antibody test systems exhibit performance differences. Conclusions The Innodx Biotech Total Antibody serum diagnosis kit is the most reliable detection system for anti-SARS-CoV-2 antibodies, which can be used together with nucleic acid tests as an alternative method for SARS-CoV-2 detecting.

Abstract Liquefied petroleum gas (LPG) is a widely used environment-friendly fuel. Previous studies have shown an increasing number of LPG-related burns. Our study was designed to evaluate the epidemiologic pattern of these injuries and provide recommendations for burn prevention. This retrospective study included all patients with LPG-related burns from eight burn centers in Zhejiang Province, China between 2011 and 2015. Database variables included patient demographics, accident characteristics, and injury characteristics. The association between different categorical variables was identified using the chi-square test. And the association between two or more means of quantitative variables was analyzed by the one-way analysis of variance or t-test. A total of 1898 patients were included, 47.31% were males and 52.69% were females. The predominant age group was 31 to 70 years (74.50%), and the majority were poorly educated and the incidence peaked from June to September. The most common place of occurrence was home (74.08%) and gas leak (96.52%) was the most common cause. The four limbs (43.33%) were the most frequently affected areas; the mean burn area was 25.19 ± 20.97% of the total body surface area and most patients (46.89%) suffered from moderate burns. The mean length of hospital stay was 17.66 ± 16.55 days and the majority of patients (89.36%) recovered with a 0.84% mortality rate. Our findings reflected that the increase in incidence rate was alarming, and the causes resulting in LPG-related burns have not gained much attention yet. Therefore, this calls for simple but strict measures aiming at each hazardous step during the use of LPG to prevent these burn injuries.

Abstract Clinical-pathological sessions are a good method for solving diagnostic and/or therapeutic problems in patients with hemopathies. In these sessions, errors made during health care given to the patient can be detected. By analyzing how and why these errors are made, we can improve patient care and prevent further mistakes. The objective of this study is to describe 34 errors identified in 874 patients with hemopathies at clinical-pathological meetings in two centers, performed with the aim of solving a diagnostic problem and/or a therapeutic decision or due to a great interest of the case, in two institutions, over 22 years (1982–2004). An intererdisciplinary team of hematology specialists gathered every week at interactive sessions of about 45 minutes each, in both institutions. The methodology of sessions was: a description of the medical history of a patient in a one or two-page report and a revision of the different samples (peripheral blood, bone marrow and lymph node morphology, immunocytochemistry, flow-cytometry, cytogenetic and molecular studies) with the aid of a microscope and a TV monitor. A diagnostic and/or treatment were proposed at the end of the session. Eight-hundred and seventy-four reports were analyzed. All the diagnostics were classified: chronic lymphoproliferatives disorders (445), myeloproliferative and myelodysplastic syndromes (136), acute leukemias (136), other haematological diseases (74), non-haematological diseases (31), without a diagnosis after the meeting (52). We identified diagnostic (D) and therapeutic (T) mistakes and considered as the main causes of the medical error (mistake in the diagnosis and/or treatment): lack of expertise (LE), malpractice (MP), impetuosity (IM), bad logistic support (LS), inexplicable (IN). We divided the 22 years into two decades and each error was classified in one of these two groups. Our own mistakes (OM) and the errors made in other institutions (OI) were identified. A comparison between number of errors made in the first 11 years and the second 11 years was made using a Chi-square test. P&lt;0.05 was considered statistically significant. Thirty-four errors (4 %) were detected, being more D and T (20) rather than only D (14). The type of error detected was: 17 LE, 7 MP, 5 IM, 3 LS, 2 IN. Twenty errors were OM and 14 were made in OI. The difference in the proportion of errors detected during the first and the second decade (6.6 % vs 2.8 %, respectively) was statistically significant (p=0.05). No error led to the death of any patient or were life-threatening in any way. Errors may be made in the diagnosis and treatment of hematologic patients. Although the rate of error found appears to be high, it can be considered as low, since the cases were presented in scientific sessions because of diagnostic and/or therapeutic problems. One of the best ways of improving how to care for future patients is to detect and analyze the errors made. Many lessons can be learnt in this way.
