Point of Care Ultrasound Used to Diagnose Nontyphoidal Endocarditis.

Point of care ultrasound (POCUS) can make an expedited diagnosis, which might lead to early correct management. POCUS should be used in a systemic and integrated approach to evaluate multiple organs in patients with sepsis and septic shock. We present a rare case of sepsis due to nontyphoidal Salmonella endocarditis with splenic abscess in which a multiorgan POCUS examination led to expedited treatment.

Hypocalcemia in Patients With Osteoporosis and Normal Renal Function, Treated With Denosumab, a Retrospective Analysis.

Objective: The reported hypocalcemia in postmenopausal women with osteoporosis who received Denosumab was low (0.05%-1.7% to 7.4%). The major prediction factors were vitamin D and calcium levels and renal function. The objective is to evaluate the incidence of hypocalcemia in patients with osteoporosis, normal renal function, and vitamin D who received Denosumab. Method: A retrospective analysis was conducted using the medical records (2022-2023). We looked for hypocalcemia (albumin-adjusted calcium lower than 2.2 mmol/L). Results: Two hundred one postmenopausal women diagnosed with osteoporosis and received denosumab treatment were included. All patients received vitamin D3 capsules and calcium supplementation. The mean age of the patient was 75.7 ± 7.0 years (56-91 years). Hypocalcemia was observed in 46 (23%) patients following a subcutaneous dose of Denosumab 60 mg. Median calcium was 2.25 mmol/L (minimum: 0.890 mmol/L, maximum: 2.6 mmol/L). Fourteen (30.4%) patients had severe hypocalcemia (<1.8 mmol/L) and required parenteral correction. A comparison between hypocalcemia and patients with normal calcium indicated that the significant predictor of hypocalcemia was pretreatment parathyroid hormone levels (9.9 ± 11.8vs 7.6 ± 2.56 pmol/L, respectively; P < .005). The prognostic role of parathyroid hormone for the denosumab-associated hypocalcemia was assessed using ROC curve analysis. For the cut-off value of Parathyroid hormone = 6.8 pmol/L, giving serum parathyroid measurement an AUC of 0.668 (0.599-0.737) - P = .0007; sensitivity 85%; specificity 52%. Conclusion: Hypocalcemia induced by the denosumab treatment is more prevalent than previously shown in patients with osteoporosis receiving adequate calcium and vitamin D supplements. An elevated parathyroid hormone predicts hypocalcemia related to denosumab therapy in patients with normal calcium and vitamin D levels.

Comparative analysis of COVID-19 and influenza prevalence among Egyptian pilgrims returning from Hajj and Umrah in 2022: epidemiology, clinical characteristics, and genomic sequencing.

PURPOSE: To describe the changes that occurred in the SARS-CoV-2 and influenza Prevalence, epidemiology, clinical picture, and prevalent genotypes among the Egyptian pilgrims returning from Hajj and Umrah 2022 seasons. METHODS: Pilgrims were contacted at the airport and invited to participate in the survey. Pilgrims who consented were interviewed using a standardized line list that included participant demographics, respiratory symptoms if any, previous COVID-19 infection, influenza vaccination whereas COVID-19 vaccination information were collected from vaccination cards. Participants were asked to provide throat and nasopharyngeal swabs for SARS-CoV-2 and influenza testing using RT-PCR and a subset of isolates were sequenced. Descriptive data analysis was performed to describe the epidemiology and clinical symptoms of SARS-CoV-2 and influenza. Prevalence rates of SARS-CoV-2 and influenza during Hajj were calculated and compared to Umrah surveys using chi2 and t-test with a significance level < 0.05. RESULTS: Overall, 3,862 Egyptian pilgrims enrolled, their mean age was 50.5 ± 47 years, half of them were > 50 years of age and 58.2% were males. Of them, 384 (9.9%) tested positive for SARS-CoV-2 and 51 (1.3%) for influenza viruses. Prevalence of SARS-CoV-2 infections (vaccine breakthrough) increased significantly between the Umrah and Hajj surveys (6.7% vs. 9.9%, p < 0.001), and variants of the virus varied considerably. Whereas no significant difference was found in influenza prevalence, vaccine coverage and vaccine breakthrough infection rates (11.7 vs. 9.2%, 26.9 vs. 26.8%, and 1.4 vs. 1.1% respectively). CONCLUSIONS: SARS-CoV-2 prevalence among Egyptian pilgrims returning from Hajj in July increased with reduced vaccine effectiveness compared to Umrah in March 2022 suggesting a possible wave of SARS-CoV-2 in the upcoming winter.

Multiorgan Ultrasonography for the Diagnosis of Pulmonary Embolism.

The main ultrasound criterion for diagnosing pulmonary infarction is the presence of triangular/wedge-shaped or rounded, hypoechogenic, homogeneous, pleura-based lesions. When used in point-of-care, ultrasonography of several organs can facilitate the diagnosis of pulmonary embolism in a patient presenting with chest pain. We describe a case of chest pain which we thought was due to angina, but point-of-care ultrasonography directed us to a diagnosis of pulmonary embolism. LEARNING POINTS: Point-of-care ultrasonography can help the clinician make a rapid diagnosis in patients with acute respiratory failure.The main ultrasound criterion for diagnosing pulmonary infarction is the presence of triangular/wedge-shaped or rounded, hypoechogenic, pleura-based lesions.

Point-of-Care Ultrasound to Detect Dilated Coronary Sinus in Adults.

Detecting dilated coronary sinus when assessing patients in an acute emergency with point-of-care ultrasound (POCUS) is important for differential diagnosis, including the detection of persistent left superior vena cava (PLSVC) and right ventricular dysfunction. Cardiac POCUS with agitated saline injections through the left and right antecubital veins is a simple bedside test to make the diagnosis. We present a 42-year-old woman with first-time rapid atrial flutter in whom POCUS confirmed the presence of dilated coronary sinus and PLSVC.

COVID-19 outcomes among pregnant and nonpregnant women at reproductive age in Egypt.

BACKGROUND: To describe demographic, clinical and epidemiological characteristics of pregnant and nonpregnant women with confirmed COVID-19 at reproductive age and determine risk factors of COVID-19 severe outcomes during pregnancy. METHODS: A retrospective study for females aged 18-49 with confirmed COVID-19 by RT-PCR in Egypt, February-July 2020. Data were obtained from Egypt National Surveillance, bivariate and multivariate analysis for demographic and clinical characteristics and outcomes of COVID-19 between pregnant and nonpregnant women including ICU admission, need for ventilator and death was performed. RESULTS: A total of 23 095 females were identified, with mean (SD) age of 35.1 (8.1) year. Of those, 408 (1.8%) were pregnant, with mean (SD) age of 29.3 (8.1) years. Compared to nonpregnant, pregnant patients were more likely to be admitted to hospital (OR = 1.7 CI = 1.4-2.1), ICU (OR = 2.4, CI = 1.3-4.3), need ventilator (OR = 3.9, CI = 2.1-7.4) and have severe outcome (OR = 3.0, CI = 1.9-4.7). Factors associated with severe outcome included: pregnancy, age > 30 years, underlying medical conditions, and living in rural areas. CONCLUSION: Pregnant women with COVID-19 are at higher risk of severe symptoms and outcome including ICU admission, requiring ventilator and death. To reduce risk of severe outcome, counseling about for seeking medical care and health education about COVID-19 preventive measures should be performed.

The Impact of Implementing the Egypt Pandemic Preparedness Plan for Acute Respiratory Infections in Combating the Early Stage of the COVID-19 Pandemic, February-July 2020: Viewpoint.

This article briefly describes Egypt's acute respiratory infection (ARI) epidemic preparedness and containment plan and illustrates the impact of implementation of the plan on combating the early stage of the COVID-19 epidemic in Egypt. Pillars of the plan include crisis management, enhancing surveillance systems and contact tracing, case and hospital management, raising community awareness, and quarantine and entry points. To identify the impact of the implementation of the plan on epidemic mitigation, a literature review was performed of studies published from Egypt in the early stage of the pandemic. In addition, data for patients with COVID-19 from February to July 2020 were obtained from the National Egyptian Surveillance system and studied to describe the situation in the early stage of the epidemic in Egypt. The lessons learned indicated that the single most important key to success in early-stage epidemic containment is the commitment of all partners to a predeveloped and agreed-upon preparedness plan. This information could be useful for other countries in the region and worldwide in mitigating future anticipated ARI epidemics and pandemics. Postepidemic evaluation is needed to better assess Egypt's national response to the COVID-19 epidemic.

Coinfection With SARS-CoV-2 and Influenza A(H1N1) in a Patient Seen at an Influenza-like Illness Surveillance Site in Egypt: Case Report.

BACKGROUND: Sentinel surveillance of influenza-like illness (ILI) in Egypt started in 2000 at 8 sentinel sites geographically distributed all over the country. In response to the COVID-19 pandemic, SARS-CoV-2 was added to the panel of viral testing by polymerase chain reaction for the first 2 patients with ILI seen at one of the sentinel sites. We report the first SARS-CoV-2 and influenza A(H1N1) virus co-infection with mild symptoms detected through routine ILI surveillance in Egypt. OBJECTIVE: This report aims to describe how the case was identified and the demographic and clinical characteristics and outcomes of the patient. METHODS: The case was identified by Central Public Health Laboratory staff, who contacted the ILI sentinel surveillance officer at the Ministry of Health. The case patient was contacted through a telephone call. Detailed information about the patient's clinical picture, course of disease, and outcome was obtained. The contacts of the patient were investigated for acute respiratory symptoms, disease confirmation, and outcomes. RESULTS: Among 510 specimens collected from patients with ILI symptoms from October 2019 to August 2020, 61 (12.0%) were COVID-19-positive and 29 (5.7%) tested positive for influenza, including 15 (51.7%) A(H1N1), 11 (38.0%) A(H3N2), and 3 (10.3%) influenza B specimens. A 21-year-old woman was confirmed to have SARS-CoV-2 and influenza A(H1N1) virus coinfection. She had a high fever of 40.2 °C and mild respiratory symptoms that resolved within 2 days with symptomatic treatment. All five of her family contacts had mild respiratory symptoms 2-3 days after exposure to the confirmed case, and their symptoms resolved without treatment or investigation. CONCLUSIONS: This case highlights the possible occurrence of SARS-CoV-2/influenza A(H1N1) coinfection in younger and healthy people, who may resolve the infection rapidly. We emphasize the usefulness of the surveillance system for detection of viral causative agents of ILI and recommend broadening of the testing panel, especially if it can guide case management.

Acalculous Cholecystitis Complicated by Liver Abscess as a Manifestation of Cholesterol Embolization Syndrome - Infrequent Manifestation Precipitated by a Common Procedure.

Cholesterol embolization syndrome (CES) is an atherosclerotic complication affecting different systems with various clinical manifestations, usually triggered iatrogenically by interventional and surgical procedures or thrombolytic therapy, although spontaneous cases have been reported. The hepatobiliary system can also be affected when the showered cholesterol crystals obliterate small vessels within this system causing both ischaemic and inflammatory responses. We describe a case of a male patient who initially developed multiple lacunar cerebral infarcts 10 days post-thrombolytic therapy and percutaneous coronary intervention (PCI) due to acute myocardial infarction. Several weeks later he developed acalculous cholecystitis complicated by liver abscess and kidney injury. The consequences and latency of manifestations within different organs and the temporal relationship with well-known trigger factors raised the suspicion of CES. LEARNING POINTS: Cholesterol embolization syndrome (CES) is an atherosclerotic complication that usually develops after a vascular procedure/surgery or thrombolytic therapy or, rarely, spontaneously, and results in nonspecific cutaneous, renal, central nervous system and, less often, gastrointestinal manifestations that may mimic other systemic diseases.The delayed appearance of multi-organ manifestations from the precipitating factors may lead to difficulties in diagnosing CES.Complicated acalculous cholecystitis can be one of the infrequent hepatobiliary manifestations of CES.
