Incidence, risk factors and outcomes of acute kidney injury in surgical intensive care unit octogenarians at the Jordan University Hospital.

BACKGROUND: Acute kidney damage (AKI) is among the most severe consequences observed in surgical intensive care units (SICUs). We aim to observe the incidence, risk factors, and outcomes of acute kidney injury in SICU octogenarians. METHODS: A cross-sectional retrospective study was conducted at the SICU of Jordan University Hospital (JUH), a tertiary teaching hospital in a developing country, between January 2018 and December 2019. Patients who were 80 years or older at the time of data collection were included. The definition of AKI was based on Kidney Disease Improving Global Outcomes (KDIGO) criteria. Demographic, clinical, and laboratory data were reviewed. RESULTS: A total number of 168 patients were included. The mean age was 84.0 ± 3.8 years, and 54.8% of the participants were women. Of those, 115 (68.5%) had surgery before or during ICU stay, and 28.7% of the patients' surgeries were an emergency surgery. Also, 47.8% of surgeries were considered by anesthesia to be high-risk surgeries. A total of 55 patients (32.7%) developed AKI during their SICU stay. The factors that were significantly associated with AKI in the ICU patients included use of beta blocker [AOR: 3.7; 95% CI: 1.2-11.8; p = 0.025], and inotropes [AOR:4.0; 95% CI: 1.2-13.3; p = 0.03]. The factors that were significantly associated with mortality in the ICU included using mechanical ventilation [AOR:18.7; 95% CI: 2.4-141.9; p = 0.005] and inotropes use [AOR: 12.3; 95% CI: 1.2-120.7; p = 0.031]. CONCLUSIONS: The incidence of AKI during SICU stay in this study was 32.7% and it was significantly associated with the use of beta blockers, mechanical ventilation, and inotropes. The mortality rate among octogenarians who developed AKI during SICU stay was 36.4%. Further studies are needed globally to assess the incidence of AKI in octogenarian surgical patients and identify risk factors to provide preventative measurements and strategies.

Cardiac myxoma: clinical characteristics, surgical intervention, intra-operative challenges and outcome.

OBJECTIVE: The objectives of this retrospective study were to characterize the clinical presentation, diagnostic findings, surgical approaches, intra-operative challenges and complications following the surgical treatment of cardiac myxoma in two of the largest referral hospitals in Jordan. METHODS: Medical records of all patients presented to the cardiology department during the period between 1984 and 2016 were reviewed. Criteria for inclusion in the study were: (1) patients who were presented for cardiac evaluation due to symptoms suggestive of a primary cardiac problem, (2) completed medical records, including results of echocardiography suggestive of intra-cardiac occupying mass, (3) the surgical operation was undertaken and intra-operative data was available, (4) a histological diagnosis of myxoma was available and (5) the discharge status and follow-up data were available for at least 2 years after initial surgery. RESULTS: A total of 27 patients fulfilled the criteria for inclusion in the study. The average age was 42 years. Thirteen of the patients were females and 14 patients were males. The most common clinical presentations were dyspnea (29.6%) and murmurs (22.2%). Non-specific signs, such as weight loss, fever, fatigue, arthralgia and anemia, were reported in 10 (37%) patients. Signs related to systemic embolization were reported in 9 (33.3%) of the patients, involving the upper and lower extremities (55.6%), brain ischemia and vision loss (54.4%). Tumors in all patients were successfully resected under cardiopulmonary bypass support. The tumor was pedunculated in 17 (62.9%) of the patients and the size of the tumors varied from 1 to 7 centimeters in diameter. The tumor was located in the left atrium in 21 patients (77.7%), in the right atrium in 4 patients (14.8%), in the right ventricular side of the septum in 1 patient (3.7%) and involving the tricuspid valve in 1 patient (3.7%). The left atrial approach was used in 3 patients, a right atrial approach in 4 patients and a bi-atrial approach in 20 patients. The most common concomitant cardiac pathology was coronary artery disease in 3 patients and an atrial septal defect in one patient. The most common intra-operative challenges were inter-atrial communication (2 patients), large defect in the tricuspid valve leaflet (1 patient) and involvement of the inter-ventricular septum (1 patient). In the post-operative period, 1 patient suffered a stroke. In the post-operative period, the most common complications were stroke (1 patient) and recurrence of the tumor (2 patients). CONCLUSION: The success rate after surgical removal of cardiac myxoma in this study was substantial and complications were rare.

Libman-Sacks Endocarditis with Unusual Large Size Vegetation Involving the Mitral Valve.

Antiphospholipid syndrome (APS) is an autoimmune hypercoagulable disorder characterized by thrombophilia, vascular thrombosis, and recurrent abortions associated with persistent antiphospholipid antibodies. APS may exist in its primary form, or more commonly is found to be associated with variety of rheumatic disorders, such as systemic lupus erythematosus. Cardiac involvement is not an uncommon complication in primary antiphospholipid patients. Libman-Sacks lesions are typically small, sessile, and wart-like, varying in size from 1-4 mm. Here we present an unusual case of a 37 year-old pregnant woman who suffered from heart failure associated with primary antiphospholipid syndrome and Libman-Sacks endocarditis, with large vegetations involving the mitral valve. The patient underwent mitral valve replacement with a mechanical prosthesis.

Valve Surgery in a Low-Volume Center in a Low- and Middle-Income Country: A Retrospective Cross-Sectional Study.

Background: Valvular heart disease (VHD) has a significant prevalence and mortality rate with surgical intervention continuing to be a cornerstone of therapy. We aim to report the outcome of patients undergoing heart valve surgery (HVS) in a low-volume center (LVC) in a low- and middle-income country (LMIC). Methods: A cross-sectional retrospective study was conducted at the Jordan University Hospital (JUH), a tertiary teaching hospital in a developing country, between April 2014 and December 2019. Patients who underwent mitral valve replacement (MVR), aortic valve replacement (AVR), tricuspid valve replacement (TVR), double valve replacement (DVR), CABG + MVR, and CABG + AVR patients were included. Thirty-day and two-year mortalities were taken as the primary and secondary outcomes, respectively. Results: A total number of 122 patients were included, and the mean age was 54.46 ± 14.89 years. AVR was most common (42.6%). There was no significant association between STS mortality score or Euroscore II with 30-day and 2-year mortality. Conclusion: LVC will continue to have a role in LMICs, especially during development to HICs. Further global studies are needed to assert the safety of HVS in LVC and LMICs.

Investigating the Utility of the SOFA Score and Creating a Modified SOFA Score for Predicting Mortality in the Intensive Care Units in a Tertiary Hospital in Jordan.

Background: The utility of the Sequential Organ Failure Assessment (SOFA) score in predicting mortality in the intensive care unit (ICU) has been demonstrated before, but serial testing in various settings is required to validate and improve the score. This study examined the utility of the SOFA score in predicting mortality in Jordanian ICU patients and aimed to find a modified score that required fewer laboratory tests. Methods: A prospective observational study was conducted at Jordan University Hospital (JUH). All adult patients admitted to JUH ICUs between June and December 2020 were included in the study. SOFA scores were measured daily during the whole ICU stay. A modified SOFA score (mSOFA) was constructed from the available laboratory, clinical, and demographic data. The performance of the SOFA, mSOFA, qSOFA, and SIRS in predicting ICU mortality was assessed using the area under the receiver operating characteristic curve (AUROC). Results: 194 patients were followed up. SOFA score (mean ± SD) at admission was significantly higher in non-survivors (7.5 ± 3.9) compared to survivors (2.4 ± 2.2) and performed the best in predicting ICU mortality (AUROC = 0.8756, 95% CI: 0.8117-0.9395) compared to qSOFA (AUROC = 0.746, 95% CI: 0.655-0.836) and SIRS (AUROC = 0.533, 95% CI: 0.425-0.641). The constructed mSOFA included points for the hepatic and CNS SOFA scores, in addition to one point each for the presence of chronic kidney disease or the use of breathing support; it performed as well as the SOFA score in this cohort or better than the SOFA score in a subgroup of patients with heart disease. Conclusion: SOFA score was a good predictor of mortality in a Jordanian ICU population and better than qSOFA, while SIRS could not predict mortality. Furthermore, the proposed mSOFA score which employed fewer laboratory tests could be used after validation from larger studies.

Complement Terminal Pathway Activation is Associated with Organ Failure in Sepsis Patients.

BACKGROUND: Complement plays a pivotal role in the immune response to infection. Several studies demonstrated complement activation in sepsis, yet little is known of the relationship of complement terminal pathway activation and the clinical characteristics of sepsis patients. Therefore, we investigated serum C5, soluble C5b-9 (sC5b-9), and soluble CD59 (sCD59) and their relation to organ failure in sepsis patients in the intensive care unit (ICU). METHODS: In this prospective cohort study, all available patients admitted to the adult ICUs between June 2020 and January 2021 were included. Patients were divided into sepsis and non-sepsis groups according to the Sepsis-3 criteria, serum samples from both groups were investigated for the levels of C5, sC5b-9, and sCD59 using commercial sandwich ELISA kits. RESULTS: We analyzed 79 serum samples, 36 were from sepsis patients. We found that sepsis patients had significantly lower C5 (83.6± 28.4 vs 104.4± 32.0 µg/mL, p = 0.004) and higher sCD59 (380.7± 170.5 vs 288.9± 92.5 ng/mL, p = 0.016). sC5b-9, although higher in sepsis patients, did not reach statistical significance (1.5± 0.8 µg/mL vs 1.3± 0.7 µg/mL, p = 0.293). Sepsis patients who died during their ICU stay had significantly higher sCD59 compared to those who survived (437.0 ± 176.7 vs 267.8 ± 79.7 ng/mL, p = 0.003, respectively). Additionally, C5 and sCD59 both correlated to SOFA score in the sepsis group (rs = -0.44, P = 0.007 and = 0.43, P = 0.009, respectively), and a similar correlation was not found in the non-sepsis group. DISCUSSION: In sepsis patients, levels of C5 and sCD59, but not sC5b-9, correlated to the severity of organ damage measured by SOFA. A similar correlation was not found in non-sepsis patients. This indicated that organ damage associated with sepsis led to a more pronounced terminal pathway activation than in non-sepsis patients, it also indicated the potential of using C5 and sCD59 to reflect sepsis severity.

Atrial Septal Defect Repair in Adolescent and Adult Patients, a Cross Sectional Study at Jordan University Hospital, a Tertiary Hospital in a Developing Country.

Objective: We aim to report our heart team's experience in repair of Secundum atrial septal defect (ASD) in adolescent and adult patients at Jordan University Hospital (JUH). Methodology: A retrospective observational study of 44 patients who underwent secundum ASD closure by transcatheter closure (TCC) or Minimally Invasive Cardiac Surgery (MICS) at JUH. Patients who were treated at an age of 14 years or older regardless of the age of diagnosis were included. SPSS and Microsoft Excel were used to analyze the data. Results: A total of 44 patients with secundum ASD were treated during the period of (January 2015 and December 2019). The mean age was 34.1 (±14.3) years. Thirty-four patients underwent TCC, 9 underwent surgical closure and one had a hybrid procedure. We had no mortality and 2 minor morbidities. After a mean follow-up period of 13.2-/+13.6 months, most patients experienced improved symptoms, and there was a significant reduction of right ventricular dimension from 33.1 (±8.74) to 24 (±4.67) mm (p=0.0001). Conclusion: ASD closure whether TCC or MICS is a safe procedure with very low morbidity. A heart team approach is a necessity in the era of advances in both MICS surgery and TCC approach. A heart team provides the patients with a variety of safe and cosmetic solutions that allow the patients to have a fast management and recovery phase in rapid time through providing the merits and avoiding the complications of each modality, the team allows low volume centers in developing countries to achieve an excellent outcome.

Serum ACE2 Level is Associated With Severe SARS-CoV-2 Infection: A Cross-Sectional Observational Study.

Objectives: Angiotensin-converting enzyme 2 (ACE2) represents the primary receptor for SARS-CoV-2 to enter endothelial cells, causing coronavirus disease of 2019 (COVID-19). In this study, we investigate the association between circulating ACE2 levels with the severity of COVID-19. Methods: Serum ACE2 levels were measured in 144 COVID-19-positive subjects at hospital admission, and 123 COVID-19-negative control subjects. The association between ACE2 and clinical outcomes was analyzed. Results: About 144 COVID-19 patients and 123 healthy controls data were analyzed, the mean age of patients was 62 years and 50% of them were males. The mean age of the control group was 55 years and 63% were males. ACE-II level was measured and compared between COVID-19 patients and controls and revealed no significant differences (P > .05). ACE-II level was measured in COVID-19 patients and compared between different patient's subgroups, ACE II level was not dependent on gender, smoking, ACE intake, or comorbidities (P > .05), and was significantly correlated with cardiovascular diseases (CVS) (P-value = .046) ICU admission (P-value = .0007) and Death (P-value = .0082). Conclusion: There was no significant difference between the COVID-19 and Control group, however, ACE2 serum level was significantly higher in patients with COVID-19 who were critically ill or non-survivors, its increased level is also associated with length of stay. Elevated ACE2 level is associated with the severity of COVID-19 disease, and it has the potential to be a predictor of the severity of the disease.

The Value of Auditing Surgical Records in a Tertiary Hospital Setting.

BACKGROUND: Assessing and improving quality of care should be of paramount importance to health care systems and providers. This study aimed to evaluate the quality of surgical records at the Jordan University Hospital. METHODS: We used the previously validated Surgical Tool for Auditing Records (STAR) to retrospectively evaluate the quality of surgical records of patients who underwent surgery in the general surgery department from 2016 to 2021. Total STAR and section-specific STAR scores were compared using the two independent sample Student's ttest on SPSS Statistics, version 23 (IBM Corp, Armonk, NY). RESULTS: A total of 488 records were selected and evaluated using the STAR. The total STAR scores significantly improved steadily throughout the years compared to the baseline in 2016, reaching the highest in 2021. All domains had improved compared to the baseline except for anesthesia records that did not change from an already high baseline. The highest improvements between STAR domains were observed in Initial Clerking and Consent domains. CONCLUSION: Our study demonstrates that significant improvements in the quality of surgical records can be achieved by simply using an electronic record entry system, personnel education, and systematic auditing.

Medical students and risk of COVID-19 infection: A descriptive cross-sectional study from the University of Jordan.

BACKGROUNDS: The coronavirus disease-2019 (COVID-19) pandemic with increasing morbidity and mortality has impacted the lives of the global population, including medical education. With the return of on-site medical education in Jordan, it is important to know whether this would pose any risk of COVID-19 infection in medical students. OBJECTIVE: To investigate COVID-19 infection infection rates among medical students and whether there is difference between preclinical and clinical students' infection rate. METHODS: The study is a cross-sectional study, designed to (1) determine the incidence of COVID-19 in clinical and preclinical medical students (2) determine if there is a difference in infection rates between clinical and preclinical students. The study was situated at the University of Jordan and its affiliated hospitals. Data were collected from the 4th of December 2020 till the 17th of February 2021through a structured web-based questionnaire. RESULTS: A total of 1,830 responses were retrieved. Thirty-nine percent were males, and (61.5%) were females. Overall, 237(13%) of students reported testing positive for COVID-19 infection by PCR, of which 123 were clinical students (15.2%) and 114 were pre-clinical students (11.2%), representing a relative risk of 1.36 of COVID-19 infection among clinical students compared to pre-clinical students. This difference is statistically significant (P = 0.010). Rates of COVID-19 in females 13%; CI 7.5,18.4), were very close to those of males (12.9%; 95% CI 6.0,19.8). Positive COVID-19 cases peaked in November and October forming 36.3% and 32.9% of the cases, respectively. CONCLUSION: The incidence of positive COVID-19 tests was found to be higher among clinical students as compared to pre-clinical students. Commitment to general health safety precautions did not appear to be protective enough for clinical students. It is fundamental that additional strategies, including access to vaccines, are set, and deficiencies in current protections are identified to maintain students' safety and well-being.

Characteristics of Adult Sepsis Patients in the Intensive Care Units in a Tertiary Hospital in Jordan: An Observational Study.

Sepsis is a global health issue that is commonly encountered in the intensive care unit (ICU) and is associated with high morbidity and mortality. Available data regarding sepsis in low- and middle-income countries (LMIC) is lacking compared to higher income countries, especially using updated sepsis definitions. The lack of recent data on sepsis in Jordan prompted us to investigate the burden of sepsis among Jordanian ICU patients. We conducted a prospective cohort study at Jordan University Hospital, a tertiary teaching hospital in the capital, Amman. All adult patients admitted to the adult ICUs between June 2020 and January 2021 were included in the study. Patients' clinical and demographic data, comorbidities, ICU length of stay (LOS), medical interventions, microbiological findings, and mortality rate were studied. Descriptive and inferential statistics were used to analyse data from patients with and without sepsis. We observed 194 ICU patients during the study period; 45 patients (23.3%) were diagnosed with sepsis using the Sepsis-3 criteria. Mortality rate and median ICU LOS in patients who had sepsis were significantly higher than those in other ICU patients (mortality rate, 57.8% vs. 6.0%, p value < 0.001, resp., and LOS 7 days vs. 4 days, p value < 0.001, resp.). Additionally, sepsis patients had a higher combined number of comorbidities (2.27 ± 1.51 vs. 1.27 ± 1.09, p value < 0.001). The use of mechanical ventilation, endotracheal intubation, and blood transfusions were all significantly more common among sepsis patients. A causative organism was isolated in 68.4% of sepsis patients with a prevalence of Gram-negative bacteria in 77.1% of cases. While the occurrence of sepsis in the ICU in Jordan is comparable to other regions in the world, the mortality rate of sepsis patients in the ICU remains high. Further studies from LMIC are required to reveal the true burden of sepsis globally.

Improving the Quality of Medical Documentation in Orthopedic Surgical Notes Using the Surgical Tool for Auditing Records (STAR) Score.

Aims Due to the significant value held by medical records in terms of influencing patient care and medico-legal cases, this study aimed to investigate the quality of surgical notes and their improvement through periodic auditing during a six-year period at a major tertiary hospital. Methodology This study retrospectively evaluated surgical records of patients undergoing elective orthopedic surgeries at Jordan University Hospital from 2016 to 2021 using the Surgical Tool for Auditing Records (STAR) validated questionnaire. This questionnaire is composed of six distinct sections aimed to quantify the quality of medical records and demonstrate their associated deficiencies. Pre- and post-audit STAR scores were analyzed using the two independent sample t-test on Statistical Package for Social Sciences (SPSS) version 23.0 (IBM Corp. Armonk, NY). Results A total of 454 records were randomly selected and evaluated using the STAR questionnaire. There was an overall significant trend of improvement in the quality of records in all evaluated years compared to the 2016 baseline. The most pronounced improvements were in the records of 2021 as compared to the 2016 baseline (97.4 ± 0.7 vs. 94.3 ± 1.6; p:<0.05), in which the Initial Clerking, Subsequent Entries, and Operative Record domains had the most significant magnitude of change. The Consent and Anesthesia domains plateaued over the study's period in terms of overall quality. The most improved STAR domain was the Discharge Summary domain, in which four subsections (follow-up, diagnosis, complications, and medications on discharge) had significant STAR score increases (all; p:<0.05). Conclusion Our study implies that simple measures, including personnel education and training and periodic auditing, are effective measures in increasing the quality of surgical records. High-quality medical records need to be sustained and continuously improved, as they contribute to better health care, promote research, and contribute to economic gains through cost-effective practices.

E-Learning during COVID-19 pandemic; Turning a crisis into opportunity: A cross-sectional study at The University of Jordan.

OBJECTIVES: To assess the medical students' satisfaction and knowledge attainment through distant learning during the COVID-19 pandemic. METHODS: This is a cross-sectional, self-reported, questionnaire-based study that was conducted at the School of Medicine at the University of Jordan in April 2020. The targeted population was the students at the school of medicine. An online questionnaire was created using Google Forms. Satisfaction and knowledge attainment among students were assessed using independent-samples t-test. RESULTS: A total of 1000 medical students completed the survey, 506 (50.6%) basic science students and 494 (49.4%) were clinical science students. 655 (65.5%) of all students were either satisfied or neutral with e-learning. 63.6% of basic science students and 59.5% of clinical students stated that they gained and understood knowledge in the same way as or better than they did before initiation of exclusive e-learning. Satisfaction and knowledge gain were significantly affected by student preparedness (p < 0.000), teacher performance (p < 0.000), and website accessibility (p < 0.000). CONCLUSION: Transition from traditional in-class teaching to distant learning, whether full or blended, is an inevitable step. In our sample, students were generally satisfied with e-learning and the knowledge attained using it. There was a significant relation between satisfaction and attainment and preparedness of students, teachers, and the medical school.

Anomalous inferior vena cava drainage to the left atrium with successful staged repair in a 32-year-old woman with arthritis.

This report describes a case involving anomalous drainage of inferior vena cava (IVC) to the left atrium diagnosed when the patient was 32 years old. The tricuspid valve and the right ventricle were small. Successful surgical repair was performed, with significant improvement of the patient's clinical status. The use of exercise testing with pulse oxymetry monitoring aided in the decision of timing for closure of the iatrogenically created atrial septal defect.

Descending necrotising mediastinitis, a fatal disease to keep in mind.

Descending necrotising mediastinitis, a term used by Estrera (1983) [1], is a rare and serious disease requiring prompt diagnosis and immediate aggressive surgical therapy. It should be considered in the differential diagnosis of acute mediastinal widening. We report an unusual case of primary retropharyngeal abscess complicated by descending necrotising mediastinitis and bilateral empyema in a 56-year-old diabetic man. The diagnosis of descending necrotising mediastinitis (DNM) was established by the characteristic findings on computed tomography. The patient was treated by cervicotomy and staged bilateral posterolateral thoracotomy.

Heart Disease in Adult Syrian Refugees: Experience at Jordan University Hospital.

BACKGROUND: Since 2011, 1.26 million Syrians have immigrated to Jordan, increasing demands on Healthcare service. Information about cardiovascular disease (CVD) in Syrian refugees in general, and specifically in Jordan, is unknown. OBJECTIVES: The study aimed to describe CVD in Syrian refugee adults who were referred to Jordan University Hospital (JUH) in terms of diagnosis, presentation, outcome, sources of funding for treatment, and to follow these patients after their discharge. METHODS: From January 2012 to October 2016, retrospective analysis was performed on the data of Syrian patients who were referred to JUH. This study describes the diagnoses, treatment, and outcome. It also discusses the funding sources; a follow-up was conducted until January 2017. RESULTS: There were 969 patients referred to JUH with CVD; median age was 56 years, 686 (72.2%) of them were males and 283 (27.8%) were females. Of the patients, 584 had hypertension (60%), 308 (31%) had diabetes mellitus, 281 (29.0%) suffered from dyslipidemia, and 237 were smokers (24%). There were 69.6% who had coronary artery disease (CAD) and 20 patients (2%) had valvular heart disease. Treatment was offered to 489 patients (49.5%), but only 322 (65.8% of treatment offered and 33.2% of referrals) of them received the intended treatment. Mortality rate was 3% and loss of follow-up was 49.2%. Funding for procedures mostly came from the Jordanian Health Aid Organization, the United Nations, NGOs, and charities. Sixty-four (13.3% of referred) patients were denied any funding during the time frame of this study. CONCLUSIONS: CVD is a major issue for both Syrian refugee patients and the Jordanian healthcare system. CAD and classic cardiovascular risk factors (specifically arterial hypertension, diabetes, and dyslipidemia) are most common in this specific population. Inadequate primary healthcare, suboptimal living conditions, lack of funding, and loss of patient contact are among the major challenges facing this vulnerable population.

Bronchial erosion and migration of Port-A-Cath, a case report.

INTRODUCTION: Several possible complications are known to be related to central venous catheters. PRESENTATION OF CASE: A 20-year-old lady had a catheter (Port-a-Cath) inserted in the left subclavian vein to treat Hodgkin's lymphoma. One year after insertion, on receiving intravenous chemotherapy the patient began coughing. Imaging studies showed the tip of the catheter to be crossing the superior mediastinum into the upper lobe of the right lung. The patient was taken to the operating room and the Port-a-Cath catheter was removed intact. DISCUSSION: Migration is a rare complication associated with insertion of these lines. Accompanying erosion into an airway is even rarer. CONCLUSION: Any unexplained deterioration in the respiratory system should raise suspicion of catheter migration and bronchial erosion.

Lack of strong association of Chlamydia pneumoniae and atherosclerosis in a Jordanian population.

INTRODUCTION: The correlation of Chlamydia pneumoniae to coronary artery disease (CAD) in Jordan was investigated in this study. METHODOLOGY: Totals of 361 atherosclerotic patients and 392 apparently healthy controls of both sexes were enrolled. C. pneumoniae-specific IgG antibodies were measured by the microimmunofluorescence assay (MIF). The presence of the bacterial DNA in the blood by polymerase chain reaction (PCR) was also tested. RESULTS: The overall IgG seroprevalence, estimated at a titer of 1/16, was insignificantly higher in patients (75.9%) than in controls (71.7%). About 59.3% of patients demonstrated seropositivity at titers ≤ 1/256, which are suggestive of chronic or presumed past infection, whereas 54.1% of controls were seropositive at these titers (p > 0.05). Analysis of gender-specific seroprevalences revealed no obvious relation between C. pneumoniae and atherosclerosis in males (78.9% and 77.9% in atherosclerotic and control males, respectively; p > 0.05). However, a significantly elevated seropositivity was detected in atherosclerotic females (71.7%) compared with control females (64.2%). On the other hand, the PCR-based detection of C. pneumoniae DNA failed to correlate the bacterium to atherosclerosis. CONCLUSIONS: We were unable to show a strong association between C. pneumoniae and CAD, potentially because of the presence of high seroprevalence of C. pneumoniae antibodies and the unreliability of the whole blood-based nested PCR technique used.

Aortopulmonary ectopic parathyroid gland and concurrent thymolipoma.

Ectopic parathyroid adenomas are considered the main cause of primary hyperparathyroidism. However, concurrent parathyroid and thymic pathologies are rarely diagnosed in the same patient. A 47-year-old man with history of diabetes mellitus, hypertension, and myasthenia gravis presented with persistent hypercalcemia. Laboratory investigations, computed tomography, and technetium-99 m sestamibi scintigraphy revealed ectopic parathyroid glands, a mediastinal mass, and an enlarged thymus. The patient underwent thymectomy and mass excision via a median sternotomy. Histopathology was consistent with ectopic parathyroid adenoma and thymolipoma. The serum calcium and parathormone concentrations normalized within 48 hours after surgery.

Spontaneous left atrial intramural hematoma associated with large hemorrhagic pericardial effusion.

Atrial intramural hematoma is a rare entity. It was reported to occur spontaneously especially in patients with recent history of cardiac surgery or cardiac trauma. In this report, a case of spontaneous intramural hematoma associated with large bloody stained pericardial effusion presented with progressive shortness of breath as the primary clinical manifestation is described. The diagnosis was tentatively achieved by transesophageal echocardiography and cardiac computed tomography scan and was later confirmed during surgery. The patient recovered uneventfully following surgery and follow-up echocardiography demonstrated complete resolution of pre-existing hematoma. .
