Arcanobacterium haemolyticum bacteremia presenting as severe sepsis: A case report and review of the literature.

Objective: to describe a case of severe sepsis and complicated bacteremia caused by Arcanobacterium haemolyticum and review similar cases in the literature. Case summary: A 26-year-old gentleman with a history of epilepsy presented with symptoms of sore throat, productive cough, periumbilical abdominal pain, watery diarrhea, nausea and vomiting, subjective fevers along with progressive jaundice for seven days. The patient had acute fulminant liver failure, septic shock, and Multi-organ failure. He required vasopressors, underwent intubation, and had grown Arcanobacterium haemolyticum in the blood and Bronchoalveolar lavage samples. He developed a peritonsillar abscess and cavitary pneumonia and required chest tube drainage followed by thoracotomy for hemothorax. The patient improved on Ampicillin-Sulbactam treatment and was treated with a total antibiotic duration of 6 weeks. He fully improved on post-discharge follow-up. Discussion: Arcanobacterium haemolyticum is a Gram-positive (sometimes Gram variable), catalase-negative facultatively anaerobic, non-motile, non-spore-forming, and variably ß-hemolytic and is known to be a cause of pharyngitis and skin and soft tissue infections. Rarely A. Haemolyticum can be associated with severe systemic infections such as infective endocarditis, systemic abscesses, osteomyelitis, and septicemia. In previous literature reviews, the source of A. haemolyticum depended on the host, and pharyngeal and upper respiratory sources were likely to be associated with immunocompetent hosts. Conclusion: A. haemolyticum should be included in the differential diagnosis of bacterial pharyngitis complicated by severe systemic illness. Penicillins are the most commonly used antibiotics for treating A. haemolyticum bacteremia, and macrolides can be used for Penicillin's treatment failure.

[Surgical treatment of a patient with stage v multinodular toxic goiter, severe thyrotoxicosis, strangulation syndrome and severe comorbidities]. / Khirurgicheskoe lechenie patsientki s mnogouzlovym toksicheskim zobom V stepeni, tireotoksikozom tyazheloi stepeni, kompressionnym sindromom i tyazhelymi soputstvuyushchimi zabolevaniyami.

The authors describe thyroidectomy in a patient with multinodular toxic goiter stage V, severe thyrotoxicosis complicated by thyro-cardiac disease, strangulation syndrome and severe comorbidities. Nodular euthyroid goiter was first diagnosed in 1992, and resection of the right thyroid lobe was performed. Progressive enlargement of thyroid gland and thyrotoxicosis occurred after coronavirus infection in February, 2020. Along with progression of thyrotoxicosis and strangulation of cervical organs, the patient suffered from portal vein thrombosis, pulmonary embolism. Myeloproliferative disease with essential thrombocythemia was also diagnosed. Volume of the right and left thyroid lobes was 69 and 101.3 cm3, respectively. X-ray examination of the esophagus revealed narrowing at C6 level up to 5-8 mm. Surgery time was 2 hours, dimension of removed right thyroid lobe - 10.0×7.5×6.5 cm, left thyroid lobe - 11.0×6.5×5.5 cm, total weight - 348 g. The patient was discharged in 6 days after surgery.

Diagnostic performance of serum pentraxin-3 in pediatric acute appendicitis: a prospective diagnostic validation study.

INTRODUCTION: Pediatric acute appendicitis (PAA) is a pathology with a high rate of diagnostic error. The search for new diagnostic tools is justified by the high morbidity and healthcare costs associated with diagnostic error. METHODS: We designed a prospective study to validate serum pentraxin-3 (PTX3) as a diagnostic tool in PAA. Participants were divided into three groups: (1) patients with no underlying pathology (2) patients with non-surgical abdominal pain and (3) patients with a confirmed diagnosis of PAA. For further analyses, patients in group 3 were divided into complicated or uncomplicated PAA. Quantitative variables were expressed as medians and interquartile ranges and categorical variables as percentages. Quantitative variables were compared using the Kruskal-Wallis test and the Mann-Whitney U test. Diagnostic performance was evaluated with ROC curves. RESULTS: This study included 215 patients divided into group 1 (n = 63), group 2 (n = 53) and group 3 (n = 99). Median serum PTX3 values were 2.54 (1.70-2.95) ng/mL, 3.29 (2.19-7.64) ng/mL and 8.94 (6.16-14.05) in groups 1, 2 and 3, respectively (p = 0.001). Patients with complicated PAA showed significantly higher values than patients with uncomplicated PAA (p = 0.04). The AUC (group 2 vs. 3) was 0.77 (95% CI 0.69-0.85) and the best cut-off point was at 7.28 ng/mL, with a sensitivity of 61.3% and a specificity of 73.1%. The AUC (complicated vs. uncomplicated PAA) was 0.65 (95% CI 0.54-0.77) and the best cut-off point was 12.33 ng/mL, with a sensitivity of 51.72% and a specificity of 72.73%. CONCLUSIONS: The diagnostic ability of serum PTX3 in PAA is only moderate and therefore it cannot be considered a definitive diagnostic test. The discriminatory ability of PTX3 between complicated and uncomplicated PAA is poor. These findings, which contrast with those reported to date, should be validated with future properly designed prospective studies.

Has the frequency of complicated appendicitis changed in children in the first year of the COVID-19 pandemic?

Background: The COVID-19 pandemic period suggests that the rate of complications may have increased in patients requiring surgical treatment due to the fact that they could not come to the hospital at the onset of the symptom. This study aims to evaluate the difference in the frequency of complicated appendicitis and postoperative complications in the COVID-19 pandemic.Patients included those who underwent appendectomy in 1 year before the COVID-19 pandemic and in the first year of the pandemic. The patients were categorized into two groups: pre-pandemic and pandemic periods. Clinical and histopathology results were compared between the pre-pandemic and pandemic periods. Results: A total of 407 patients were included in the study, 207 of whom were included during the pre-pandemic and 200 of whom during the pandemic period. The mean time to hospital admission after the onset of symptoms was 1.3 ± 0.9 days, pre-pandemic, and 1.4 ± 0.8 days during the pandemic group. In the pre-pandemic group, 0.4% intrabdominal abscess developed and 37.5% complicated appendicitis was detected. In the pandemic group, it was found that there were 1% abscess, 0.5% wound infection, 0.5% brid ileus, and 31.9% complicated appendicitis. The pre-pandemic group length of hospitalization was 2.4 ± 0.8 days, and the pandemic was 2.1 ± 0.9 days There was no difference between pre-pandemic and pandemic groups in terms of age, gender, white blood cell count, duration of symptoms, postoperative complications and frequency of complicated appendicitis, and duration of hospitalization. Conclusions: In the first year of the COVID-19 pandemic, we found that the rate of complicated appendicitis and postoperative complications were not different from pre-pandemic.

Analysis of appendicitis management during COVID-19 pandemic: A study of Chinese adult cohorts.

Background: Healthcare seeking behavior has been widely impacted due to the restricted movements of individuals during the Coronavirus disease-19 (COVID-19) pandemic. This study aims to perform risk stratification in patients requiring timely intervention during the recovery periods. Methods: Operation notes of acute appendicitis (AA) patients within a hospital were analyzed during three six-month periods (23 January-23 July in 2019, 2020, and 2021, respectively). Patient data were collected retrospectively including demographics, pre-emergency status, perioperative information, postoperative outcomes, and follow-up results. Results: 321 patients were included in this study, with 111, 86, and 124 patients in 2019, 2020, and 2021 groups, respectively. The median age of patients decreased by 4 years in 2020 as compared to that in 2019. The proportion of pre-hospitalization symptoms duration of more than 48 h in the 2020 group was higher (36.05% in 2020 vs. 22.52% in 2019). Length of hospital stay (LOS) in 2020 was shorter than it was during the same period in 2019 (4.77 vs. 5.64) and LOS in 2021 was shorter than in 2019 (4.13 vs. 5.64). Compared to the lockdown period, the proportion of patients with recurrent AA was higher in the post-lockdown period (15.1% vs. 27.4%). The median age was 34 years (vaccinated) vs. 37 years (unvaccinated). Logistic regression suggests that elevated C-reactive protein (CRP) (OR = 1.018, CI = 1.010-1.028), white cell count (WBC) (OR = 1.207, CI = 1.079-1.350), female (OR = 2.958, CI = 1.286-6.802), recurrent (OR = 3.865, CI = 1.149-12.997), and fecalith (OR = 2.308, CI = 1.007-5.289) were associated with complicated appendicitis (CA). Conclusion: The lockdown measures during the COVID-19 epidemic are shown to be correlated with a reduction in the proportion of AA patients who underwent surgery, particularly in older adults. Risk factors for CA include elevated CRP, WBC, female, recurrent, and fecalith.

Complicated Grief: The Lived Experiences of Those Bereaved By COVID-19.

The morbidity and mortality rates of COVID-19 pandemic are increasing, and many families have lost their loved ones. This study explored the experiences of families living in Iran who lost a loved one to COVID-19. The researchers apply a descriptive phenomenological approach and draw on in-depth interviews with 18 family members who had lost at least one family member because of COVID-19. Data were analyzed using Colaizzi's method. After reviewing and comparing the consistency of the codes, crisis in crisis, circumstances of death and its consequences, and lack of preservation of patient dignity were extracted as main categories. Neglecting grieving families and related issues can lead to delays and difficulties in the process of recovery and intensification of their psychosocial pressures. Acquiring more knowledge about different impacts of COVID-19 will be helpful for providing timely and better rehabilitation.

Hyponatremia-A New Diagnostic Marker for Complicated Acute Appendicitis in Children: A Systematic Review and Meta-Analysis.

BACKGROUND: Acute appendicitis in the pediatric population remains a diagnostic challenge for clinicians. Despite many biochemical markers, imaging modalities and scoring systems, initial misdiagnosis and complication rates are high in children. This suggests the need for investigations directed towards new diagnostic tools to aid in the diagnosis. Recent studies have shown a correlation between serum sodium levels and complicated appendicitis. Although the exact reasons for hyponatremia in patients with complicated appendicitis are not known, there is persuasive data to support the role of pro-inflammatory cytokines such as IL-6 in the non-osmotic release of antidiuretic hormone. This meta-analysis aims to investigate all available data on hyponatremia as a diagnostic marker of complicated appendicitis in the pediatric population. METHODS: The literature search was conducted by two independent investigators according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The scientific databases (PubMed, EMBASE, Web of Science, and Scopus) were systematically searched for relevant studies using the keywords (hyponatremia) AND (appendicitis) AND (children). The methodological quality was assessed using a validated scale, and RevMan 5.4 software was utilized for pooled analysis. RESULTS: Seven studies were included in the final meta-analysis, five of which were retrospective. A total of 1615 and 2808 cases were distributed into two groups: group A with complicated appendicitis and group B with uncomplicated acute appendicitis, respectively. The studies compared serum sodium levels of patients among the groups. Pooling the data demonstrated significantly lower serum sodium levels in children with complicated appendicitis vs. the non-complicated appendicitis (WMD: -3.29, 95% CI = -4.52 to -2.07, p < 0.00001). The estimated heterogeneity among the included studies was substantial and statistically significant (I2 = 98%, p < 0.00001). CONCLUSION: The results of the present meta-analysis indicate that hyponatremia has potential to be utilized as a biochemical marker in the diagnosis of complicated appendicitis in the pediatric population. However, well designed prospective diagnostic efficiency studies are essential to consolidate the association between hyponatremia and complicated acute appendicitis.

Incidence of complicated appendicitis during the COVID-19 pandemic: A systematic review and meta-analysis.

Introduction: Measures taken to prevent the spread of coronavirus disease 2019 (COVID-19) slow surgical processes, and patients are avoiding presenting at emergency departments during the outbreak because of fears of contracting the contagious disease. To analyze the rate of complicated appendicitis before and during the COVID-19 pandemic. Methods: We systematically reviewed the PubMed and SCOPUS databases for articles published from 2000 to 2021. Including the retrospective review data collected from our hospital of patients aged ≥18 years old who were diagnosed with acute appendicitis. The primary outcome of complicated appendicitis incidence was compared between before and during the COVID-19 pandemic period. We performed a meta-analysis using a random-effects model analysis. Results: A total 3559 patients were included for meta-analysis. The overall rate of complicated appendicitis was significantly higher during the pandemic (relative risk, 1.55; 95% confidence interval [CI], 1.26-1.89). The time from onset of symptoms to hospitalisation was 0.41 h longer during the pandemic, which was not significantly different (standardized mean difference, 0.41, 95% CI, -0.03 to 1.11). The operating time during the pandemic was significantly shorter than that before the pandemic (83.45 min and 71.65 min, p = 0.01). Conclusion: There are correlation between the pandemic and severity of acute appendicitis. The higher rate of complicated appendicitis in the pandemic indicates that patients require timely medical attention and appropriate treatment despite fears of contracting disease.

Suspected and Confirmed Acute Appendicitis During the COVID-19 Pandemic: First and Second Quarantines-a Prospective Study.

Purpose: COVID-19 posed an unprecedented modern global healthcare crisis affecting both elective and urgent surgeries. The aim of this study is to evaluate the difference in the presentation of acute appendicitis (AA) before and during the COVID-19 era, the first and second quarantines. Methods: We performed a prospective study from December 2018 to May 2021. Two cohorts were analysed, one with patients who presented to the emergency department (ED) with suspected AA and the second with confirmed AA. Both cohorts were divided into four groups: before COVID-19, during the first quarantine, between the first and second quarantine, and during the second quarantine. Data such as demographics, the time to first contact with the healthcare provider and time to operation, laboratory tests, clinical stage of AA, length of stay, and COVID-19 status were collected. A total of 469 patients were enrolled. Results: A total of 209 patients were male (45%) and 260 were female (55%), with the median age being 33 years (24-45). In the first cohort of suspected AA, there was no difference in sex; however, more older patients presented to the ED during the first quarantine (41 years) compared with other groups (28.5, 36, and 32.5 years), p < 0.000. Before the pandemic, there was a shorter duration of symptoms to first contact with the healthcare provider (13 h) compared with other groups, p = 0.001. In the second cohort of confirmed AA, there was a shorter period of time to operation from first symptoms before the pandemic (22 h) compared with other groups (30, 35, 30.5 h), p < 0.000. There were more complicated gangrenous, perforated appendicitis or periappendicular abscess in Group 2 and 3 (26, 22 and 10%, and 26, 22 and 2%, respectively) compared with Group 1 (20, 4 and 3%) and Group 4 (22, 12, and 2%), p = 0.009. Hospital stay was longer during the first quarantine (3 days) compared with other groups (2 days), p = 0.009. Six patients were COVID-19 positive: one from Group 3 and five from Group 4 (p > 0.05). Conclusions: Our study suggests that during the first quarantine of the COVID-19 pandemic, there was delayed presentation to the ED with suspected AA and there was a greater proportion of complicated appendicitis and longer hospitalization in confirmed cases as well.
