ABSTRACT

OBJECTIVE: We aimed to compare mortality and complication rates in patients treated for obstructive jaundice before and during the COVID-19 pandemic in a tertiary care center in Serbia. METHODS: We conducted a retrospective cohort study among a first group of patients treated between 1 January 2017 and 1 January 2019. The second group was treated between 1 March 2020 and 1 March 2022. RESULTS: The first group comprised 35 patients, and the second group (in which all patients were SARS-CoV-2 positive) included 18 patients; 37 and 16 patients were treated for malignant and benign diseases, respectively. The groups did not differ significantly regarding the diagnoses and treatment received. The second group showed significantly higher aspartate aminotransferase levels and lower white blood cell, C-reactive protein, and interleukin 6 levels. Mortality and complication rates did not differ significantly between groups. All deceased patients in the second group had significant radiologic findings associated with COVID-19 pneumonia. CONCLUSIONS: COVID-19 infection is a risk factor in treating obstructive jaundice. This study illustrates the potential influence of COVID-19 on mortality after obstructive jaundice treatment. COVID-19 pneumonia may be a significant risk factor for mortality in patients treated for obstructive jaundice.

ABSTRACT

Angiolipomatous hamartoma is a benign mesenchymal proliferation of unknown aetiology. Only a few cases have been documented in the published literature. This current case report describes a 57-year-old female patient who was hospitalized for an assessment of a previously radiologically-verified splenic lesion and further treatment. The patient had been surgically treated 10 years previously; a lobectomy of the superior left pulmonary lobe had been performed in order to remove a verified tumour lesion. A complete radiological examination was undertaken, which verified a spleen of a size that was within the physiological range, with a centrally-located lobular tumour lesion. Given the risk of splenic rupture, as well as the fact that the lesion's aetiology was still undetermined, and finally the fact that differential diagnostics indicated the possibility of a metastasis, the patient was treated surgically. Laparoscopic splenectomy, in the treatment of splenic diseases, even rare ones such as this, is not a novelty. Indeed, it needs to be applied as the standard approach, with the well-known benefits that the minimalized approach offers.

ABSTRACT

(1) Background: The aim of this study was to assess the incidence and the risk factors for healthcare-associated Clostridioides difficile infection (HA-CDI) in patients with COVID-19 and without this infection. (2) Methods: A single-center, prospective observational study was conducted at the University Clinical Hospital Center in Belgrade, Serbia, from January 2019 to December 2021. The entire hospital was a COVID-dedicated hospital for 12 months during the study period. The incidence density rates and risk factors for HA-CDI in patients with and without COVID-19 are presented. (3) Results: The incidence rates of HA-CDIs were three times higher in patients with COVID-19. The HA-CDI-COVID-patients were younger (69.9 ± 12.6 vs. 72.5 ± 11.6; p = 0.017), admitted from another hospital (20.5% vs. 2.9; p < 0.001), had antimicrobial therapy before CDI (99.1% vs. 91.3%, p < 0.001), received two or more antibiotics (p = 0.030) during a longer period (p = 0.035), received proton pump inhibitors (95.9% vs. 50.0%, p < 0.001) during a longer period (p = 0.012) and steroids (32.8% vs. 20.4%, p < 0.001). During the last month before their current hospitalization, a higher percentage of patients without COVID-19 disease were hospitalized in our hospital (p < 0.001). Independent predictors for HA-CDIs in patients with COVID-19 were admission from another hospital (p = 0.003), the length of antibiotic administration (0.020), and the use of steroids in therapy (p < 0.001). The HA-CDI predictors in the non-COVID patients were older age (p = 0.017), advanced-stage renal failure (p = 0.005), chemotherapy (p = 0.003), and a low albumin level (0.005). (4) Conclusion: Higher incidence rates of HAI-CDIs in COVID-19 patients did not occur due to reduced infection control precautions and hygiene measures but due to antibiotic therapy and therapy with other drugs used during the pandemic.

ABSTRACT

INTRODUCTION: Health care workers have had a challenging task since the COVID-19 outbreak. Prompt and effective predictors of clinical outcomes are crucial to recognize potentially critically ill patients and improve the management of COVID-19 patients. The aim of this study was to identify potential predictors of clinical outcomes in critically ill COVID-19 patients. METHODS: The study was designed as a retrospective cohort study, which included 318 patients treated from June 2020 to January 2021 in the Intensive Care Unit (ICU) of the Clinical Hospital Center "Bezanijska Kosa" in Belgrade, Serbia. The verified diagnosis of COVID-19 disease, patients over 18 years of age, and the hospitalization in ICU were the criteria for inclusion in the study. The optimal cutoff value of D-dimer, CRP, IL-6, and PCT for predicting hospital mortality was determined using the ROC curve, while the Kaplan-Meier method and log-rank test were used to assess survival. RESULTS: The study included 318 patients: 219 (68.9%) were male and 99 (31.1%) female. The median age of patients was 69 (60-77) years. During the treatment, 195 (61.3%) patients died, thereof 130 male (66.7%) and 65 female (33.3%). 123 (38.7%) patients were discharged from hospital treatment. The cutoff value of IL-6 for in-hospital death prediction was 74.98 pg/mL (Sn 69.7%, Sp 62.7%); cutoff value of CRP was 81 mg/L (Sn 60.7%, Sp 60%); cutoff value of procalcitonin was 0.56 ng/mL (Sn 81.1%, Sp 76%); and cutoff value of D-dimer was 760 ng/mL FEU (Sn 63.4%, Sp 57.1%). IL-6 ≥ 74.98 pg/mL, CRP ≥ 81 mg/L, PCT ≥ 0.56 ng/mL, and D-dimer ≥ 760 ng/mL were statistically significant predictors of in-hospital mortality. CONCLUSION: IL-6 ≥ 74.98 pg/mL, CRP values ≥ 81 mg/L, procalcitonin ≥ 0.56 ng/mL, and D-dimer ≥ 760 ng/mL could effectively predict in-hospital mortality in COVID-19 patients.

ABSTRACT

INTRODUCTION: Risk stratification is an important aspect of COVID-19 management, especially in patients admitted to ICU as it can provide more useful consumption of health resources, as well as prioritize critical care services in situations of overwhelming number of patients. MATERIALS AND METHODS: A multivariable predictive model for mortality was developed using data solely from a derivation cohort of 160 COVID-19 patients with moderate to severe ARDS admitted to ICU. The regression coefficients from the final multivariate model of the derivation study were used to assign points for the risk model, consisted of all significant variables from the multivariate analysis and age as a known risk factor for COVID-19 patient mortality. The newly developed AIDA score was arrived at by assigning 5 points for serum albumin and 1 point for IL-6, D dimer, and age. The score was further validated on a cohort of 304 patients admitted to ICU due to the severe form of COVID-19. RESULTS: The study population included 160 COVID-19 patients admitted to ICU in the derivation and 304 in the validation cohort. The mean patient age was 66.7 years (range, 20-93 years), with 68.1% men and 31.9% women. Most patients (76.8%) had comorbidities with hypertension (67.7%), diabetes (31.7), and coronary artery disease (19.3) as the most frequent. A total of 316 patients (68.3%) were treated with mechanical ventilation. Ninety-six (60.0%) in the derivation cohort and 221 (72.7%) patients in the validation cohort had a lethal outcome. The population was divided into the following risk categories for mortality based on the risk model score: low risk (score 0-1) and at-risk (score > 1). In addition, patients were considered at high risk with a risk score > 2. By applying the risk model to the validation cohort (n = 304), the positive predictive value was 78.8% (95% CI 75.5% to 81.8%); the negative predictive value was 46.6% (95% CI 37.3% to 56.2%); the sensitivity was 82.4% (95% CI 76.7% to 87.1%), and the specificity was 41.0% (95% CI 30.3% to 52.3%). The C statistic was 0.863 (95% CI 0.805-0.921) and 0.665 (95% CI 0.598-0.732) in the derivation and validation cohorts, respectively, indicating a high discriminative value of the proposed score. CONCLUSION: In the present study, AIDA score showed a valuable significance in estimating the mortality risk in patients with the severe form of COVID-19 disease at admission to ICU. Further external validation on a larger group of patients is needed to provide more insights into the utility of this score in everyday practice.

ABSTRACT

INTRODUCTION: Mortality among critically ill COVID-19 patients remains relatively high despite different potential therapeutic modalities being introduced recently. The treatment of critically ill patients is a challenging task, without identified credible predictors of mortality. METHODS: We performed an analysis of 160 consecutive patients with confirmed COVID-19 infection admitted to the Respiratory Intensive Care Unit between June 23, 2020, and October 2, 2020, in University Hospital Center Bezanijska kosa, Belgrade, Serbia. Patients on invasive, noninvasive ventilation and high flow oxygen therapy with moderate to severe ARDS, according to the Berlin definition of ARDS, were selected for the study. Demographic data, past medical history, laboratory values, and CT severity score were analyzed to identify predictors of mortality. Univariate and multivariate logistic regression models were used to assess potential predictors of mortality in critically ill COVID-19 patients. RESULTS: The mean patient age was 65.6 years (range, 29-92 years), predominantly men, 68.8%. 107 (66.9%) patients were on invasive mechanical ventilation, 31 (19.3%) on noninvasive, and 22 (13.8%) on high flow oxygen therapy machine. The median total number of ICU days was 10 (25th to 75th percentile: 6-18), while the median total number of hospital stay was 18 (25th to 75th percentile: 12-28). The mortality rate was 60% (96/160). Univariate logistic regression analysis confirmed the significance of age, CRP, and lymphocytes at admission to hospital, serum albumin, D-dimer, and IL-6 at admission to ICU, and CT score. Serum albumin, D-dimer, and IL-6 at admission to ICU were independently associated with mortality in the final multivariate analysis. CONCLUSION: In the present study of 160 consecutive critically ill COVID-19 patients with moderate to severe ARDS, IL-6, serum albumin, and D-dimer at admission to ICU, accompanied by chest CT severity score, were marked as independent predictors of mortality.

ABSTRACT

OBJECTIVE: Functional outcomes were prospectively compared between the standard Roux-en-Y and Double-tract reconstruction following a total gastrectomy and D2 lymphadenectomy. METHODS: One hundred ten patients with gastric cancer were divided into two groups by the type of reconstruction. Age, gender, T stage, AJCC stage, length of operation, BMI (body mass index, kg/m2), time to soft diet, postoperative leakage of the esophagojejunostomy (EJS), stricture of the EJS, meal intake, and quality of life (QOL) were recorded. RESULTS: The mean age in the R-Y group was 61.57, with the SD of 9.53, while in the DT group the mean age was 60.17 with a SD of 9.92. The BMI decline in the R-Y group was 4.09 with a SD of 1.11, while in the DT group it was 2.85 with a SD of 1.27. We found a highly significant statistical difference between the two groups in the rate of the BMI decline (p<0,001). We found no statistically significant difference regarding QOL between the two groups, p>0.05. CONCLUSIONS: The Double tract reconstruction is a simple procedure and the rate of the BMI decline is much smaller compared to the Roux-en-Y group.

ABSTRACT

OBJECTIVE: The aims of our study were to assess the prevalence and distribution of Gram-negative (G-) bacteria in hospital isolates, their sensitivity to the third- and fourth-generation cephalosporins (c3 and c4), therapeutic use of c3 and c4 in the treatment of G- infections and drug utilisation data. RESEARCH DESIGN AND METHODS: This cross-sectional study collected medical records data from the General Hospital "Gornji Milanovac" (GM) and the University Medical Center "Bezanijska kosa" (BK). The time frame of the study was 12 months. Microbiological and clinical parameters, and c3/c4 drug utilisation were analysed. RESULTS: Escherichia coli were the most predominant pathogen in GM and BK, accounting for 43% and 28% of all G- isolates, respectively (GM), 884 G- isolates obtained from 606 patients; BK, 1766 isolates obtained from 1045 patients). Nearly half of the isolates (55% and 43%) were obtained from urine samples collected from the surgical ward (GM), and the internal medicine wards and intensive care unit (BK). On average, the resistance rate of G- strains against c3 and c4 reached 40% and 70%, respectively (lowest in E. coli, 8%-25%; highest in Acinetobacer baumannii, 67%-100%). Resistance rate of Pseudomonas spp. to cefepime and ceftazidime was low/moderate (0%-30% and 19%-47%). In BK, the adult patients were older than in GM (75 vs 66 years), with longer hospital stay (19 vs 10 days) and bacteria were isolated later during hospitalisation (10 vs 2 days). C3 and c4 were more often used in empirical therapy (83% vs 64%) in BK. Ceftazidime and cefepime were used more often in BK than in GM (2.036 vs 69 DDD/y and 586 vs. 126 DDD/y, respectively). CONCLUSION: The use of c3 and c4 in the treatment of G- infections in both hospitals should be re-evaluated in accordance with current guidelines and local resistance.

ABSTRACT

BACKGROUND: Many different benign and malignant diseases can cause obstruction of the extrahepatic biliary duct. One of the more serious complications of biliary obstruction is cholangitis leading to emergency decompression. Anatomic variations are frequent in this region; however, it has rarely been reported that the extrahepatic bile duct is compressed by the arterial vessels. CASE REPORT: We present the case of a 68-year-old woman who was admitted through the emergency department of our hospital with jaundice, abdominal pain and fever. Biochemical analyses of liver function showed increased value of AST (113 IU/L) and AST (128 IU/L). Total bilirubin was 5.88 mg/dl, conjugated bilirubin was 3.00 mg/dl, and alkaline phosphatase was 393 IU/L. We performed abdominal ultrasound (US), magnetic resonance cholangiopancreatography (MRCP), and computed tomography (CT) imaging. Multislice CT angiography showed that the arterial ring of the common hepatic artery around the common bile duct (CBD) originated from the superior mesenteric artery. Cholecystectomy and intraoperative cholangiography were performed, as well as decompression and lavage of the biliary tree. Escherichia coli was identified from bile. Dissection of the hepatoduodenal ligament confirmed that the proper hepatic artery made a vascular ring around the CBD. Finally, a T tube was placed into the CBD. During 5 years of follow-up the patient has been without recurrent episodes of jaundice. In such cases dissection of the proper hepatic artery from the common hepatic duct is the treatment of choice. CONCLUSIONS: If there are signs of cholangitis decompression and lavage of the biliary tree with "T", drainage should be performed. Vascular malformations should be considered as a possible cause of extrahepatic biliary obstruction. CT angiography may be helpful in identifying these malformations.

ABSTRACT

INTRODUCTION: Hydatidosis is a human disease caused by the larval form of Echinococcus granulosus. All organs in the human body may be affected by hydatid disease, but excluding liver and lungs, all other organs are considered as uncommon locations. Hydatid disease located in the psoas muscle is uncommon. CASE OUTLINE: The authors present a 36-year-old male living in endemic areas of Serbia, admitted due to pain and weakness of the right thigh and weight loss. Duration of symptoms was one year. CT and MRI revealed a big cystic mass (20 cm long) in the right psoas muscle. Neurological investigation showed a loss of function of the right femoral nerve. Serology for Echinococcosis was negative. Surgery was indicated and performed by median laparotomy. Total excision of the cyst was done. Pathohystology confirmed the nature of the cyst. Three years after operation the patient was without any signs of disease relapse. CONCLUSION: Echinococcal disease of the psoas has been very rarely reported, sometimes associated with paraspinal disease and often with vertebral involvement. Cystic or complex retroperitoneal tumour, pyogenic abscess of the psoas and even tuberculosis should be considered in the differential diagnosis. Treatment of choice is surgery. The greatest danger for the patient is dissemination and anaphylactic reaction. Also, compression of adjacent organs may produce significant morbidity.

ABSTRACT

BACKGROUND/AIM: Colorectal cancer (CRC) is one of the most frequent diseases and early diagnosis has a potential role to improve survival. The aim of this study was to analyze influence of delay in diagnosis on survival in patiens with colorectal cancer. METHODS: A total of 119 patients with pathohystological diagnosis of CRC were included in the study. They were operated at our Department for Surgery from 2000 to 2002. They were divided into two groups according to the duration of symptoms: early operated patients - EOP (symptoms were presented for 3 months) and late operated patients - LOP (duration of symptoms was more than 3 months). Follow-up period was 5 year. RESULTS: Weight loss, intermittent abdominal pain and anorexia were more frequent in LOP (p < 0.01). Young age, blood in stool, and tumor localized in rectum were dominant characteristics in EOP (p < 0.05). Overall delay in diagnosis was 2.19 +/- 0.79 months in EOP and 11.37 +/- 5.68 months in LOP. There was highly statistically significant difference between these two groups (p < 0.01). Overall survival was 44.75%. Five years survival was 65.9% in the group of EOP and 26.5% in the group of LOP (chi2 = 28.16, p < 0.01) Weight loss was dominant characteristics in the patients who did not survive five years (chi2 = 14.26, p < 0.01). A period of 2 months in delay in diagnosis is "cut-off' value in prediction of death (sensitivity of 75.5% and specificity of 90.3%). CONCLUSION: A delay in diagnosis and stage of the disease are highly significant factors of patients with CRC survival. In everyday medical practice higher importance should be put on weight loss, intermittent abdominal pain, change in bowel habits, as well as on syderopenic anaemia.
