RESUMO
Background: Very small intracranial aneurysms, generally considered to be those 3 mm in diameter or smaller, pose particular technical challenges for endovascular surgeons. For this reason, very small aneurysms have been excluded from many relevant studies. The aim of our research was to establish the risk factors for the occurrence of stroke complications after endovascular embolization of ruptured and unruptured small intracranial aneurysms. Methods: During the period of 2009-2023, our team performed endovascular embolizations of intracranial aneurysms in 1567 patients across four different centers within the territory of Serbia and Montenegro. Within the total number of patients mentioned, aneurysms of less than 4 mm were treated 185 times, with 119 ruptured and 66 unruptured. Results: In the group of 119 patients with ruptured small intracranial aneurysms, 19 (16%) patients had ischemia after the endovascular treatment, 6 (5%) patients had minor neurological deficits, while 13 (10.9%) patients had major neurological deficits, of which 6 (5%) patients died. In the group of 66 patients with unruptured small intracranial aneurysms, 7 (10.6%) patients had ischemia after the endovascular treatment, 5 (7.6%) patients had minor neurological deficits, and 2 (3.03%) had major neurological deficits. Multivariate binary logistic regression showed that the risk factors for the occurrence of ischemia were the patient's age, smoking and alcohol consumption. The type of endovascular treatment used also had a statistically significant effect on the development of ischemia. Conclusions: Understanding the influence of possible risk factors for the occurrence of ischemic insult after embolization of small intracranial aneurysms is of great importance. By recognizing them, periprocedural complications can be reduced to a minimum.
RESUMO
Background and Objectives: The aim of this study was to examine whether the use of an alveolar recruitment maneuver (RM) leads to a significant increase in static lung compliance (Cstat) and an improvement in gas exchange in patients undergoing laparoscopic cholecystectomy. Material and Methods: A clinical prospective intervention study was conducted. Patients were divided into two groups according to their body mass index (BMI): normal-weight (group I) and pre-obese and obese grade I (group II). Lung mechanics were monitored (Cstat, dynamic compliance-Cdin, peak pressure-Ppeak, plateau pressure-Pplat, driving pressure-DP) alongside gas exchange, and hemodynamic changes (heart rate-HR, mean arterial pressure-MAP) at six time points: T1 (induction of anesthesia), T2 (formation of pneumoperitoneum), T3 (RM with a PEEP of 5 cm H2O), T4 (RM with a PEEP of 7 cm H2O), T5 (desufflation), and T6 (RM at the end). The RM was performed by increasing the peak pressure by +5 cm of H2O at an equal inspiration-to-expiration ratio (I/E = 1:1) and applying a PEEP of 5 and 7 cm of H2O. Results: Out of 96 patients, 33 belonged to group I and 63 to group II. An increase in Cstat values occurred after all three RMs. At each time point, the Cstat value was measured higher in group I than in group II. A higher increase in Cstat was observed in group II after the second and third RM. Cstat values were higher at the end of the surgical procedure compared to values after the induction of anesthesia. The RM led to a significant increase in PaO2 in both groups without changes in HR or MAP. Conclusions: During laparoscopic cholecystectomy, the application of RM leads to a significant increase in Cstat and an improvement in gas exchange. The prevention of atelectasis during anesthesia should be initiated immediately after the induction of anesthesia, using protective mechanical ventilation and RM.

Background: Corynebacterium, Nocardia, Rhodococcus, Mycobacterium, as well as Gordonia genera belongs to the genus Gordonia, Actinomycetia class. Gordonia bronchialis is a nitrate-reducing, urease-producing, non-motile, force aerobe with a rod-like figure that is known to arrangement into sessile, cord-like groups. This systematic review aimed to establish whether and what invasive infections in humans were caused by Gordonia bronchialis, and to evaluate outcomes of administered antibiotic treatment. Methods: We have registered this systematic review in PROSPERO database of systematic reviews and meta-analyses with the number CRD42022369974. Results: A total of 24 publications were included (22 case reports and two case series) with 28 individual cases. The oldest patients had 92 years, and the youngest patients had 13 years. Clinical signs of infection were present in six patients (21%). All isolates were susceptible to ciprofloxacin, imipenem, and amikacin. Vancomycin was the most frequently used antibiotic with nine cases followed by ciprofloxacin, ceftriaxone, and amoxicillin/clavulanic acid. Conclusion: Although there are no standardized recommendations to date, successful treatment with a favorable outcome has most often been carried out with fluoroquinolones, vancomycin with or without aminoglycosides, as well as carbapenems.
RESUMO
Intensive care units (ICUs) are expert hospital areas that provide treatment and 24 h care for people who are very sick. Sepsis represents a serious, severe condition and it can lead to septic shock and multiple organ dysfunction syndromes and is one of the most common reasons for patients' hospitalization in ICUs. We wanted to explore the prognostic values of interleukin (IL) 33, soluble suppression of tumorigenicity 2 (sST2), IL 27, and galectin 3 in critically-ill patients. We assumed that these parameters in combination or alone could predict mortality in ICU patients. This research represents a clinical non-randomized prospective study, performed at the Medical Military Academy, a tertiary care hospital in Belgrade, Serbia. The patients were divided in four groups: patients with sepsis (peritonitis, pancreatitis, trauma) and patients without sepsis (trauma). Total number of patients enrolled in the study was 151 and average years of patients were 56.48. The values greater than the cut-off were the predictors of mortality. The IL-33, IL-27 as well as galectin-3 can successfully predict the outcome of critically-ill patients in ICUs. The sST2, cannot predict death in critically-ill patients as a single prognostic factor. However, the combination of at least two biomarkers: IL-33, sST2, IL-27, and galectin-3, gives very significant results in predicting the outcome in patients admitted to ICUs.
RESUMO
(1) Background: The aim of our study was to determine the role of oxidative stress (OS) during early evaluation of acute ST-elevated myocardial infarction (STEMI) and non-ST-elevated myocardial infarction (NSTEMI) patients in order to define the role of redox balance in profiling the development of myocardial infarction (MI). (2) Methods: This prospective observational case-control study included 40 consecutive STEMI and 39 NSTEMI patients hospitalized in the coronary care unit of the cardiology clinic at the Kragujevac Clinical Center, Serbia, between 1 January 2016 and 1 January 2017. Blood samples were collected from all patients for measuring cardio-specific enzymes at admission and 12 h after admission to evaluate systemic oxidative stress biomarkers and the activity of antioxidant enzymes. (3) Results: In this study, participants were predominately female (52%), with a mean age of 56.17 ± 1.22 years old in the STEMI group and 69.17 ± 3.65 in the non-STEMI group. According to the Killip classification, the majority of patients (>50%) were at the second and third level. We confirmed the elevation of superoxide anion radicals in the non-STEMI group 6 h after admission in comparison with the STEMI and CTRL groups, but levels had decreased 12 h after admission. Levels of hydrogen peroxide were statistically significantly increased in the NSTEMI group. A positive correlation of superoxide anion radicals and levels of troponin I at admission was observed (r = 0.955; p = 0.045), as well as an inverse correlation between reduced glutathione and levels of NT-pBNP measured 6 h after admission (r = -0.973; p = 0.027). (4) Conclusions: We confirmed that superoxide anion radicals and reduced glutathione observed together with hs-troponin I at admission and NT-pBNP during hospital treatment could be predictors of ST evolution.
RESUMO
Background: Serratia marcescens (SM) is a Gram-negative pathogen discovered by Italian pharmacist, Bizio, in 1819. According to the literature, S. marcescens is resistant to a wide range of antibiotics, including penicillin, cephalosporin, tetracycline, macrolide, nitrofurantoin, and colistin. We conducted a systematic review of published reports, determined what invasive infections could cause SM, and established the most appropriate antibiotic therapy. Methods: We registered this systematic review on the PROSPERO registry of systematic reviews-meta-analyses before we started our research (registration number CRD42022323159). The online searches of published studies were implemented via MEDLINE, the Cochrane Central Register of Controlled Trials, EBSCO, Scopus, Google Scholar, SCIndex, and the registry of clinical studies of human participants (ClinicalTrials.gov). Results: Our study included 32 published articles (9 case series and 23 case reports). There were 57 individual cases, respectively. The oldest patient was 97 years and the youngest patient was a newborn. S. marcescens was, in most cases, isolated from blood followed by urine and cerebrospinal fluid. In most cases, sensitivity was tested to cotrimoxazole (from 27 isolates, 10 showed resistance) followed by gentamicin (from 26 isolates, 3 showed resistance) as well as amikacin (from 21 isolates, none showed resistance). Patients died from an infection in 21 cases (31%). Conclusions: Treatment of SM infections should include carbapenems or aminoglycosides in combination with third-generation (and eventually fourth-generation) cephalosporin. Cotrimoxazole should be considered in cases of uncomplicated urinary infections.
RESUMO
Validation of the fear of introduction: High levels of fear of COVID-19 may be associated with increased levels of stress, anxiety, and depression, as well as decreased resilience and life expectancy. Objective: This study aimed to translate and confirm the Serbian version of the Fear of COVID-19 scale as well as to investigate its psychometric properties. Methods: The translation and intercultural adaptation of the Fear of COVID-19 scale was performed by the leading standard of the International Society for Pharmacoeconomics and Outcome Research. When the distribution was normal, the Kolmogorov-Smirnov test was used. The reliability of the Serbian version of FCV-19S was tested by measuring the internal consistency through the value of Cronbach's alpha. Results: The original version of the Fear of COVID-19 scale was tested on a sample of 256 subjects with a mean age of 25.38 ± 12.47. The Cronbach's alpha value was 0.864. We divided the scale by the split-half method (Spearman-Brown), and the value of the coefficient for the questionnaire as a whole was 0.882. Divergent criterion validity was tested through the non-parametric correlation between the scores of the Fear of COVID-19 scale and the Fear of Hospitalization scale. A score of the Fear of COVID-19 scale was calculated as the sum of each question for each of the respondents. Convergent criterion validity was tested through the non-parametric correlation between the scores of the Fear of COVID-19 scale and the Emotional Regulation Questionnaire. Conclusion: The validated version of the scale in Serbia complements versions available in other cultures and other languages and facilitates global studies related to mental health during the COVID-19 pandemic.

Objective: Many studies so far have shown that antipsychotic therapy may have an effect on the development of metabolic syndrome in patients diagnosed with schizophrenia. Our goal was to determine whether our respondents are at risk for developing metabolic syndrome and who is more predisposed to it. Methods: In a stable phase, 60 patients diagnosed with schizophrenia were equally divided into three groups according to the drug (risperidone, clozapine, and aripiprazole monotherapy). Control group had 20 healthy examinees. Patients were evaluated first using The Positive and Negative Syndrome Scale (PANSS). Prolactin, lipid status, glycemia, insulin, cytokine values (IL-33, TGF-ß, and TNF-α) and C-reactive protein (CRP) were measured. Also, Body mass index (BMI), Homeostatic Model Assesment for Insulin Resistance (HOMA index), waist and hip circumference (WHR) and blood pressure (TA) measurement were performed in the study. Results: Patients treated with risperidone compared to healthy control subjects and aripiprazol group of patients had statistically significant difference in prolactin levels. In clozapine group compared to healthy control group values of HDL cholesterol and glucose level were statistically significant different. In aripiprazole group compared to healthy control group value of BMI was statistically significant different. Statistically significant correlations were found in TNF-α with glucose and HOMA index in risperidone treated patients and with BMI in clozapine group of patients; IL-33 with glucose in risperidone and with BMI in clozapine group of patients and TGF-ß with glucose in risperidone group, with insulin and HOMA index in clozapine group and statistically significant negative correlation with LDL cholesterol in aripiprazole group of patients. Conclusion: Patients on risperidone and clozapine therapy may be at greater risk of developing metabolic syndrome than patients treated with aripiprazole. Statistically significant difference in concentration of TNF-α and TGF-ß was in the group of patients treated with risperidone compared to healthy control group.
RESUMO
SUMMARY: Atherosclerosis is a complex disease whose pathogenesis includes endothelial activation, accumulation of lipids in the subendothelium, formation of foam cells, fat bands and formation of atherosclerotic plaque. These complex mechanisms involve different cell populations in the intimate sub-endothelium, and the S-100 protein family plays a role in a number of extracellular and intracellular processes during the development of atherosclerotic lesions. The aim of this study was to determine the phenotypic characteristics of smooth muscle cells and the consequent expression of S100 protein in atherosclerotic altered coronary arteries in advanced stages of atherosclerosis. 19 samples of right atherosclerotic coronary arteries in stages of fibro atheroma (type V lesion) and complicated lesions (type VI lesion) have been analyzed. According to the standard protocol, the following primary antibodies have been used in the immunohistochemical analysis: a-smooth muscle actin (α-SMA), vimentin and S-100 protein. All analyzed samples have been in advanced stages of atherosclerosis, fibro atheroma (stage V lesions) and complicated lesions (type VI lesions). Most of them have had the structure of a complicated lesion with atheroma or fibro atheroma as a basis, subsequently complicated by disruption (subtype VI a), hemorrhage (subtype VI b) or thrombosis (subtype VI c), as well as by the presence of several complications on the same sample. Marked hypocellularity is present in the subendothelium of plaques. Cell population at plaque margins is characterized by immunoreactivity to α-SMA, vimentin, and S100 protein. Some of these cells accumulate lipids and look like foam cells. In the cell population at the margins of the plaques, smooth muscle cells of the synthetic phenotype are present, some of which accumulate lipids and demonstrate S100 immunoreactivity. Summarizing numerous literature data and our results, we could assume that smooth muscle cells, due to their synthetic and proliferative activity in the earlier stages of pathogenesis, as well as the consequent expression of S100 protein, could accumulate lipids in the earlier stages of atherosclerosis which, in advanced stages analyzed in this study, result in immunoreactivity of foam cells of smooth muscle origin to S100 protein.
RESUMEN: La aterosclerosis es una enfermedad compleja cuya patogenia incluye activación endotelial, acumulación de lípidos en el subendotelio, formación de células espumosas, bandas grasas y formación de placa aterosclerótica. Estos complejos mecanismos involucran diferentes poblaciones celulares en el subendotelio íntimo, y la familia de proteínas S-100 juega un papel en varios procesos extracelulares e intracelulares durante el desarrollo de lesiones ateroscleróticas. El objetivo de este estudio fue determinar las características fenotípicas de las células de músculo liso y la consecuente expresión de la proteína S100 en arterias coronarias alteradas ateroscleróticas en estadios avanzados de aterosclerosis. Se analizaron 19 muestras de arterias coronarias ateroscleróticas derechas en estadios de fibroateroma (lesión tipo V) y lesiones complicadas (lesión tipo VI). Según el protocolo estándar, en el análisis inmunohistoquímico se utilizaron los siguientes anticuerpos primarios: α-actina de músculo liso (α-SMA), vimentina y proteína S-100. Todas las muestras analizadas han estado en estadios avanzados de aterosclerosis, fibroateroma (lesiones estadio V) y lesiones complicadas (lesiones tipo VI). La mayoría de ellos han tenido la estructura de una lesión complicada con ateroma o fibroateroma como base, complicada posteriormente por disrupción (subtipo VI a), hemorragia (subtipo VI b) o trombosis (subtipo VI c), así como por la presencia de varias complicaciones en la misma muestra. La hipocelularidad marcada estaba presente en el subendotelio de las placas. La población celular en los márgenes de la placa se caracterizaba por inmunorreactividad a α-SMA, vimentina y proteína S100. Algunas de estas células acumulan lípidos y parecen células espumosas. En la población celular en los márgenes de las placas, estaban presentes las células de músculo liso de fenotipo sintético, algunas de las cuales acumulaban lípidos y mostraban inmunorreactividad S100. Resumiendo numerosos datos de la literatura y nuestros resultados, podríamos suponer que las células del músculo liso, debido a su actividad sintética y proliferativa en las primeras etapas de la patogénesis, así como la consecuente expresión de la proteína S100, podrían acumular lípidos en las primeras etapas de la aterosclerosis que, en estadios avanzados analizados en este estudio, dan como resultado inmunorreactividad de células espumosas de origen muscular liso a la proteína S100.

The aim of this study is to determine whether the use of tranexamic acid (TXA) in patients with hip fracture reduces intraoperative and postoperative blood loss, and on the other hand, whether it increases thromboembolic risk. The study was performed on patients with hip fracture for a period of one year. Patients were divided into two groups (1:1): the first group receiving TXA and the second group receiving placebo. The amount of blood aspiration during the surgery was measured as well as drainage in the postoperative period of 24 h. The occurrence of deep vein thrombosis (DVT) was monitored before and after the surgery by ultrasound of the lower extremities. The amount of total blood loss was two times lower in patients who received TXA (291.8 ± 65.5 mL of blood vs 634.7 ± 150.5 mL of blood). Among the patients who developed DVT, one patient was from the group that did not receive TXA, and two patients were from the group that received TXA. The use of TXA in patients with hip fracture significantly reduces intraoperative and postoperative blood loss, without a significant thromboembolic risk.
RESUMO
Adiponectin is one of the most important molecules in the body's compensatory response to the development of insulin resistance. By trying to maintain insulin sensitivity, increase insulin secretion and prevent inflammation, adiponectin tries to maintain glucose homeostasis. Interleukin-33, which belongs to the group of alarmins, also promotes insulin secretion. Interleukin-33 might be either pro-inflammatory or anti-inflammatory depending on the disease and the model. However, interleukin-33 has shown various protective effects in CVD, obesity and diabetes. The aim of our study was to investigate the association between adiponectin and interleukin-33 in patients with metabolic syndrome. As expected, all patients with metabolic syndrome had worse parameters that represent the hallmark of metabolic syndrome compared to the control group. In the subgroup of patients with low adiponectin, we observed less pronounced characteristics of metabolic syndrome simultaneously with significantly higher values of interleukin-33 compared to the subgroup of patients with high adiponectin. Our findings suggested that adiponectin might be an early marker of metabolic syndrome that emerges before anthropomorphic, biochemical and clinical parameters. We also suggest that both interleukin-33 and adiponectin may be used to predict the inflammatory status in the early stage of metabolic syndrome.
RESUMO
Objective: The increased level of interleukin (IL)-33 is considered as a predictor of severe coronavirus disease 2019 (COVID-19) infection, but its role at different stages of the disease is still unclear. Our goal was to analyze the correlation of IL-33 and other innate immunity cytokines with disease severity. Methods: In this study, 220 patients with COVID-19 were included and divided into two groups, mild/moderate and severe/critical. The value of the cytokines, clinical, biochemical, radiographic data was collected and their correlation with disease severity was analyzed. Results: Most patients in the severe/critical group were male (81.8%) and older (over 64.5 years). We found a statistically significant difference (p < 0.05) in these two groups between clinical features (dyspnea, dry cough, fatigue, and auscultatory findings); laboratory [(neutrophil count, lymphocyte count, monocyte count, hemoglobin, plasma glucose, urea, creatinine, total bilirubin (TBIL), direct bilirubin (DBIL), aspartate aminotransferase (AST), albumin (ALB), lactate dehydrogenase (LDH), creatinine kinase (CK), D-dimer, C-reactive protein (CRP), procalcitonin (PCT), Fe, and Ferritin)], arterial blood gases (oxygen saturation-Sa02, partial pressure of oxygen -p02), and chest X-rays (CXR) lung findings (p = 0.000). We found a significantly higher serum concentration (p < 0.05) of TNF-α, IL-1ß, IL-6, IL-12, IL-23, and IL-33 in patients with COVID-19 with severe disease. In the milder stage of COVID-19, a positive correlation was detected between IL-33 and IL-1ß, IL-12 and IL-23, while a stronger positive correlation between the serum values of IL-33 and TNF-α, IL-1ß, IL-6, and IL-12 and IL-23 was detected in patients with COVID-19 with severe disease. A weak negative correlation (p < 0.05) between pO2 and serum IL-1ß, IL-12, and IL-33 and between SaO2 and serum IL-33 was noted. The positive relation (p < 0.05) between the serum values of IL-33 and IL-12, IL-33 and IL-6, and IL-6 and IL-12 is proven. Conclusion: In a more progressive stage of COVID-19, increased IL-33 facilitates lung inflammation by inducing the production of various innate proinflammatory cytokines (IL-1ß, IL-6, TNF-α, IL-12, and IL-23) in several target cells leading to the most severe forms of the disease. IL-33 correlates with clinical parameters of COVID-19 and might represent a promising marker as well as a therapeutic target in COVID-19.
RESUMO
Fever of unknown origin (FUO) presents a major diagnostic challenge as it is a consequence of many infectious as well as malignant, rheumatologic and other diseases. Here we present the case of a woman with mediastinal and abdominal lymphadenopathy who was initially suspected to have lymphoproliferative disease, but our histopathologic examination revealed sarcoidosis. Sarcoidosis, especially chronic, is a rare cause of FUO, because it usually manifests as a febrile condition. A woman presented with shoulder and ankle joint pain, mediastinal and abdominal lymphadenopathy and fever at the Infectious Diseases Clinic. Physical examination identified the presence of lupus pernio and normal respiratory noise in the lungs, and later peripheral lymphadenopathy. Peripheral blood smear indicated conspicuous eosinophilia. Biopsy examination obtained by rigid bronchoscopy suggested pulmonary sarcoidosis. Sarcoidosis and lymphoma may have similar clinical manifestations; both present as mediastinal and abdominal lymphadenopathy with constitutional symptoms. Therefore, in the diagnosis of sarcoidosis, it is important to exclude lymphoproliferative diseases and other granulomatous diseases.

Clinical manifestations of SARS-CoV-2 infection range from mild to critically severe. The aim of the study was to highlight the immunological events associated with the severity of SARS-CoV-2 infection, with an emphasis on cells of innate immunity. Thirty COVID-19 patients with mild/moderate symptoms and 27 patients with severe/critically severe symptoms were recruited from the Clinical Center of Kragujevac during April 2020. Flow cytometric analysis was performed to reveal phenotypic and functional alterations of peripheral blood cells and to correlate them with the severity of the disease. In severe cases, the number of T and B lymphocytes, dendritic cells, NK cells, and HLA-DR-expressing cells was drastically decreased. In the monocyte population proportion between certain subsets was disturbed and cells coexpressing markers of M1 and M2 monocytes were found in intermediate and non-classical subsets. In mild cases decline in lymphocyte number was less pronounced and innate immunity was preserved as indicated by an increased number of myeloid and activated dendritic cells, NK cells that expressed activation marker at the same level as in control and by low expression of M2 marker in monocyte population. In patients with severe disease, both innate and adoptive immunity are devastated, while in patients with mild symptoms decline in lymphocyte number is lesser, and the innate immunity is preserved.

INTRODUCTION: Acute aortic type III dissection is one of the most catastrophic events, with in-hospital mortality ranging between 10% and 12%. The majority of patients are treated medically, but complicated dissections, which represent 15% to 20% of cases, require surgical or thoracic endovascular aortic repair (TEVAR). For the best outcomes adequate blood transfusion support is required. Interest in the relationship between blood type and vascular disease has been established. The aim of our study is to evaluate distribution of blood groups among patients with acute aortic type III dissection and to identify any kind of relationship between blood type and patient's survival. MATERIAL AND METHODS: From January 2005 to December 2014, 115 patients with acute aortic type III dissection were enrolled at the Clinic of Vascular and Endovascular Surgery in Belgrade, Serbia and retrospectively analyzed. Patients were separated into two groups. The examination group consisted of patients with a lethal outcome, and the control group consisted of patients who survived. RESULTS: The analysis of the blood groups and RhD typing between groups did not reveal a statistically significant difference (p = 0.220). CONCLUSIONS: Our results indicated no difference between different blood groups and RhD typing with respect to in-hospital mortality of patients with acute aortic dissection type III.
RESUMO
In this report we review the unusual case of a patient with a common hepatic artery aneurysm presenting 30 years after a Billroth's II resection. A 65-year-old man with epigastric pain and 10 kg of weight loss in the previous 6 months was referred to our clinic. Computed tomography revealed the presence of an aneurysm of the common hepatic artery (HAA) of 35 mm. This HAA was surgically excluded by aneurysmectomy and prosthetic bypass. Intraoperatively we observed extensive peritoneal adhesions and connective tissue formation in the region of the hepatoduodenal and hepatogastric ligaments, and the outer wall of the HAA was tightly affixed to the root of the transverse mesocolon by connective adhesions. Retraction of the adhesions slowly brought about a continued stretching and thinning of the arterial wall likely caused the HAA.

PURPOSE: The aim of our study was to find drug-associated changes in serum levels of major electrolytes using clinical-event monitoring method. METHODS: During 1-year period, electrolyte disturbances in serum samples from patients of Clinical Center Kragujevac, Serbia, were monitored in central biochemical facility. A sample of 982 patients was randomly selected from total population of 43,120 patients whose electrolyte serum levels were measured in the facility during the study period. RESULTS: Clinically important drug-associated electrolyte disturbances were detected in 181 patient. There were 25 significant associations between the drugs and electrolyte values outside the reference range. However, only four causal connections were established: use of normal saline infusion with hypernatremia (OR 6.97, 95%CI 2.24-21.67), theophylline with acid-base disturbances (7.75, 1.46-41.02), polygeline infusion with decrease in bicarbonate levels (4.08, 1.42-11.73), and association of risperidone and hypocalcemia (4.10, 1.42-11.81). CONCLUSION: Although clinical-event monitoring method is far from optimal, it could quantify the known risks and provide evidence for credible hypothesis of drug adverse reactions, based on both relevant biological pathways and reasonable clinical thinking, as it was the case in our study.
