Concomitant Tricuspid Valve Ring Annuloplasty During Mitral Valve Surgery Versus Mitral Valve Surgery Alone: A Systematic Review and Meta-Analysis.

AIM: Although current guidelines recommend concomitant tricuspid annuloplasty for moderate or greater tricuspid regurgitation (TR) and/or dilated annulus, there remains significant variation in undertaking concomitant tricuspid valve surgery (TVA) across different centres. This meta-analysis aimed to compare the clinical outcomes of concomitant tricuspid valve surgery for patients with moderate or greater TR and/or dilated annulus at the time of mitral valve (MV) surgery. METHOD: A systematic review of the literature using six databases. Eligible studies include comparative studies on TVA concomitant with MV surgery versus MV surgery alone. A meta-analysis was performed on studies reporting outcomes of interest to quantify the effects of concomitant tricuspid ring annuloplasty. RESULTS: Two randomised controlled trials and six cohort studies were included in the analysis. 1,941 patients were included in the analysis, of whom, 1,090 underwent concomitant TVA and 851 underwent MV surgery alone. Pooled analysis demonstrated that there was less progression of moderate/severe TR in the concomitant group (3.0% vs 9.6%; odds ratio [OR] 0.29; 95% confidence interval [CI] 0.13-0.55; p=0.0001). There was no significant difference in in-hospital mortality (3.0% vs 3.8%; OR 0.79; 95% CI 0.47-1.34; p=0.38). The rate of permanent pacemaker implantation was higher in the concomitant group although this did not reach statistical significance (7.6% vs 5.3%; OR 1.30; 95% CI 0.85-1.98; p=0.23). Cardiopulmonary bypass was longer in the concomitant TVA group by 20 minutes (mean difference 13.9-26.0; p<0.00001). CONCLUSIONS: Our study demonstrated that concomitant tricuspid ring annuloplasty at the time of MV surgery is associated with a significantly lower rate of TR progression without increasing the operative mortality. There is a trend towards a higher permanent pacemaker implantation rate although this did not reach statistical significance.

Early Diagnosis of Acute Myocarditis or Dilated Cardiomyopathy in Children Younger Than 2 Years.

OBJECTIVE: Diagnosis of acute myocarditis or dilated cardiomyopathy (DCM) on initial presentation is difficult in children younger than 2 years because most present with complaints suggestive of a respiratory infection. The objective of this study is to determine whether signs, symptoms, and diagnostic studies excluding those of heart failure, done routinely in the emergency department could distinguish children younger than 2 years with acute myocarditis or DCM from those with respiratory illnesses. METHODS: Sixty-four infants' charts, 32 cases and 32 controls, were reviewed from January 1, 2009, through December 31, 2020. Controls were matched to cases with respect to age, reason, and time of admission. Signs, symptoms, and blood gases were reviewed. RESULTS: The median age is 6.5 (0.5-22) months in both groups. Infants presenting with signs of heart failure including murmurs ( P = 0.002), prolonged capillary refill ( P = 0.024), cool, mottled extremities ( P = 0.002), poor perfusion ( P = 0.001), or hepatomegaly ( P < 0.001) were more likely to be diagnosed with acute myocarditis or DCM when compared with the control group with respiratory disease. Infants with fever ( P = 0.017), nasal congestion ( P < 0.001), rhinorrhea ( P < 0.001), cough ( P < 0.001), and wheezing ( P < 0.001) were more likely to have a respiratory illness than acute myocarditis or DCM. The presence of a lower p co2 (30 [14-116] vs 40 [31-59] mm Hg, P < 0.001), lower bicarbonate (16.7 [6.3-23.4] vs 21.7 [16-28.4], P < 0.001), or an oxygen saturation > 95% ( P = 0.004) was observed in infants with acute myocarditis or DCM compared with those with respiratory illness. By multivariable analysis, infants with tachycardia in the absence of fever, metabolic acidosis, and an oxygen saturation > 95% were more likely to have acute myocarditis or DCM than those without this disease. CONCLUSIONS: Children younger than 2 years presenting to the emergency department with tachycardia and no fever, metabolic acidosis, and a high oxygen saturation should be investigated for acute myocarditis or DCM.

Efficacy and Safety of Full-thickness Resection Device (FTRD) for Colorectal Lesions Endoscopic Full-thickness Resection: A Systematic Review and Meta-Analysis.

BACKGROUND AND AIMS: Endoscopic full-thickness resection (eFTR) is a field of increasing interest that offers a minimally invasive resection modality for lesions that are not amenable for resection by conventional methods. Full-thickness resection device (FTRD) is a new device that was developed for a single-step eFTR using an over-the scope-clip. In this meta-analysis, we aim to assess the efficacy and safety of FTRD for eFTR of colorectal lesions. METHODS: A Comprehensive literature review of different databases to identify studies reporting FTRD with outcomes of interest was performed. Studies with <10 cases were excluded. Rates of histologic complete resection (R0), technical success, and complications were extracted. Efficacy was assessed by using the technical and the R0 rates whereas safety was assessed by using the complications rates. Weighted pooled rates (WPRs) and the 95% confidence interval (CI) were calculated depending on the heterogeneity (I2 statistics). RESULTS: Nine studies including 551 patients with 555 lesions were included in this study. The WPR for overall R0 was 82.4% (95% CI: 79.0%-85.5%),with moderate heterogeneity (I2=34.8%). The WPR rate for technical success was 89.25% (95% CI: 86.4%-91.7%), with low heterogeneity (I2=23.7%). The WPR for total complications rate was 10.2% (7.8, 12.8%) with no heterogeneity. The pooled rate for minor bleeding, major bleeding, postpolypectomy syndrome, and perforation were 3.2%, 0.97%, 2.2%, and 1.2%, respectively. Of 44 periappendicular lesions, the pooled rate for acute appendicitis was 19.7%. CONCLUSIONS: FTRD seems to be effective and safe for eFTR of difficult colorectal lesions. Large prospective studies comparing FTRD with conventional resection techniques are warranted.

Awareness of Birth Cohort Hepatitis C Testing Recommendation Among Baby Boomers: An Exploratory Survey Study.

OBJECTIVES: To examine population awareness of the Centers for Disease Control and Prevention's (CDC) hepatitis C virus (HCV) testing recommendation for the 1945 to 1965 birth cohort and explore the factors associated with awareness of the testing recommendation, its association with HCV testing, and respondents' data sources about the recommendation. METHODS: A cross-sectional survey was conducted to assess awareness of the CDC birth cohort testing recommendation among adults born 1945-1965 who were managed at a single academic center's internal medicine clinics or by visiting a local health fair. Data were collected on respondents' demographics and HCV-related domains, including risk factors, awareness, data sources, prior testing, and interest in information about testing. RESULTS: There were a total of 563 respondents to the survey. Forty percent were aware of the CDC's testing recommendation, with Hispanic ethnicity being the only significant predictor (odds ratio 0.59, 95% confidence interval 0.38-0.90). HCV testing rates were higher among those aware of the CDC's recommendation, as compared with those unaware (33.6% vs 24.0%, P = 0.0269). Television was the most common initial data source for the testing recommendation (64.8%), whereas healthcare providers accounted for 22.4%. CONCLUSIONS: Awareness of the CDC's testing recommendation was reported in fewer than half of the respondents and was adversely affected by minority status. Although mass media may be a key venue for HCV-related data outreach, further studies are needed on interventions to enhance the role played by healthcare providers.

Mycobacterium abscessus: a rare cause of vascular graft infection.

Prosthetic vascular graft infection (PVGI) following vascular reconstructive surgery is an uncommon but serious complication and is associated with high morbidity as well as mortality rate. Staphylococcal species are the most common organisms causing PVGI. Mycobacterium abscessus is a very rare cause of PVGI and poses a significant diagnostic and management dilemma. To the best of our knowledge, we report the third documented case of M. abscessus vascular graft infection that was diagnosed with 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) scan and treated successfully.

Cutaneous Cryptococcosis Manifested as a Large Cystic Mass: A Rare Manifestation of Cryptococcus Infection.

Cryptococcus infection is an invasive fungal infection common in immunocompromised hosts, especially in organ transplant recipients and in patients with HIV. Its presentation varies from localized skin lesions to systemic disseminated infection involving the lungs and the central nervous system (CNS). We present the case of a 50-year-old woman with diabetes mellitus type 2 (DM-2), end-stage renal disease (ESRD) status post deceased donor kidney transplantation seven and a half years ago who presented with a low-grade fever, cough, nausea, vomiting, and a large cystic mass on the right foot. A CT scan of the chest showed a 14 mm cavitary lesion in the middle lobe of the right lung. Serum and cerebrospinal fluid cryptococcal antigens were detected. MRI of the right foot showed a large multilocular lobulated septated cystic mass. Histopathology showed cryptococcus; the diagnosis was made as disseminated cryptococcus infection. She was treated with antifungal therapy successfully. A large cutaneous cystic mass is a rare cutaneous presentation of cryptococcus infection; clinicians should keep it in the differential diagnosis, especially in transplant recipient patients.

Focal Hepatocellular Carcinoma in Pancreas.

A 67-year-old man was found to have a pancreatic head mass on abdominal ultrasound. He had compensated liver cirrhosis due to hepatitis C. The fine-needle aspiration (FNA) biopsy of the mass reported an adenocarcinoma of the pancreas, while the subsequent histopathology report of the supraclavicular lymph node showed features of hepatocellular carcinoma (HCC). A second read and additional stains on the FNA specimen confirmed a hepatoid (hepatocellular) carcinoma of the pancreas. He received atezolizumab and bevacizumab and had a good response. Tumors with features of HCC outside of the liver rarely occur and even more rarely in pancreas, with less than 50 cases reported so far. Pure HCC-like morphology is the most common histological form among four subtypes and has a relatively better prognosis. Surgical resection is considered the treatment of choice if amenable and variable outcomes are reported with different chemotherapies. Challenges exist in the diagnosis and the management of this rare and intriguing entity, and the potential misdiagnosis can have grave consequences as the management is completely different for a pancreatic adenocarcinoma and hepatoid carcinoma. We report a case with a challenging diagnosis of metastatic pancreatic hepatoid carcinoma which was treated as unresectable HCC with immunotherapy and the patient had a good response.

A Tale of Two Diagnoses; Gout Vs Chronic Osteomyelitis. A Case Report.

Gout can potentially be diagnosed clinically and treated, if classical symptoms are present. In some cases, gout and osteomyelitis can have similar presenting signs and symptoms and it may be difficult to differentiate just on clinical presentation, routine laboratory workup and imaging like radiography or ultrasound. Arthrocentesis can be crucial in such scenarios to differentiate the two entities as missed opportunity to treat infectious etiology can have detrimental outcomes. We present a case of patient with ankle pain and swelling treated as recurrent gout, as there were no risk factors for osteomyelitis. Arthrocentesis confirmed the diagnosis of osteomyelitis and patient was treated with intravenous antibiotics, resulting in resolution of symptoms.

There's More Than Meets the Eye: Wolfram Syndrome in a Type I Diabetic Patient.

Wolfram syndrome (WS) is a rare neurodegenerative and genetic disorder, also known by the synonym DIDMOAD, which stands for diabetes insipidus (DI), childhood-onset diabetes mellitus (DM), optic atrophy (OA), and deafness (D). We present a case of a 25-year-old diabetic patient, using insulin for 15 years, who had increasing polyuria and polydipsia, along with progressive hearing and vision loss. Laboratory tests revealed elevated hemoglobin A1c (HbA1c) and blood sugar levels. Optic nerve, optic chiasm, pons, and brain stem atrophy was seen on magnetic resonance imaging (MRI) of brain. After workup, a diagnosis of DI was made. Once the diagnosis was reached, treatment with subcutaneous insulin and nasal desmopressin improved patient's symptoms. In juvenile diabetic patients presenting with new onset or worsening polyuria and polydipsia, the possibility of WS should be considered. Early diagnosis and initiation of appropriate management leads to improved outcomes and the quality of life.

Recurrent infection and embolism following tricuspid valve repair for infective endocarditis in an intravenous drug user: A clinical dilemma.

Management of infective endocarditis (IE) in intravenous drug users (IVDUs) can be challenging due to risk of reinfection following surgery. Although complex repair techniques that can be utilized to reconstruct the tricuspid valve after extensive debridement, treatment of active IVDU is incomplete without effective post-operative harm reduction intervention program.

Maternal serum iron status, hepcidin and interleukin-6 levels in women with preeclampsia.

Introduction: Preeclampsia can lead to a number of adverse maternal and perinatal effects. The association between iron status [serum iron, ferritin and total iron-binding capacity (TIBC)], unsaturated iron-binding capacity, hepcidin, interleukin-6 (IL-6) levels and preeclampsia is not fully understood. Objective: To assess the levels of iron status, hepcidin and interleukin-6 in women with preeclampsia compared with healthy pregnant women. Method: A case-control study (60 women were recruited in each group) was conducted at Saad Abuelela Maternity Hospital in Khartoum, Sudan. Sociodemographic and clinical data were gathered through a questionnaire. The levels of iron status, hepcidin and IL-6 were measured using applicable methods. Results: There was no significant difference in the median [interquartile range (IQR)] of age, parity or body mass index between the two groups. Moreover, the median (IQR) of the iron status, hepcidin and interleukin-6 did not differ between women with preeclampsia and healthy controls. There were no significant correlations between haemoglobin, hepcidin and IL-6. There were also no significant correlations between serum iron, serum ferritin, hepcidin and IL-6. However, there was a significant positive correlation between hepcidin and IL-6 (r = 0.393, p = 0.002). Conclusion: In this study, women with preeclampsia had levels of iron status, hepcidin and IL-6 similar to those observed in healthy pregnant women. There was no significant correlation between iron status, hepcidin and IL-6.

Diffuse Alveolar Hemorrhage: A Rare Complication of Severe Hypertension.

Severe hypertension is a rare cause of diffuse alveolar hemorrhage. We reported a case of a 43-year-old woman who presented with shortness of breath, hemoptysis, and severe hypertension. The patient was diagnosed with diffuse alveolar hemorrhage due to severe hypertension which improved after controlling her blood pressure.

Reverse Takotsubo Cardiomyopathy in a Patient With Commotio Cordis.

Takotsubo cardiomyopathy (TCM), also known as stress cardiomyopathy or "broken heart syndrome", is characterized by acute transient regional left ventricular systolic dysfunction in the absence of obstructive coronary artery disease or acute plaque rupture. Atypical forms and rare anatomical variants can have different presentations; hence, recognition becomes more important. Prognosis is much more favorable if managed appropriately. An equally infrequent cause of cardiac arrest is commotio cordis (CC). This is defined as sudden cardiac death secondary to a blunt chest wall impact leading to ventricular arrhythmias. We report a case with findings of TCM and/or CC in a patient with a blunt chest trauma in the setting of motor vehicle accident.

Acquired Immune Deficiency Syndrome Cholangiopathy: Case Series of Three Patients and Literature Review.

Cholangiopathy in acquired immune deficiency syndrome (AIDS) is being less frequently reported since antiretroviral therapy (ART) is available. It is associated with an advanced disease and seen in situations with poor access or non-compliance with ART. Liver biopsy is thought to have low yield in cases of AIDS cholangiopathy, but it can be an important tool in diagnosis, especially early in the course of the disease. The prognosis of AIDS cholangiopathy is generally not favorable, the therapy for opportunistic infections is mostly ineffective and restoration of immune system with ART remains the therapy of choice. We are sharing our experience of diagnosing and managing three cases of AIDS cholangiopathy.

A Randomized, Double-Blind, Placebo-Controlled, Multicenter Study to Evaluate the Safety and Efficacy of ThymoQuinone Formula (TQF) for Treating Outpatient SARS-CoV-2.

There is an urgent need for an oral drug for the treatment of mild to moderate outpatient SARS-CoV-2. Our preclinical and clinical study's aim was to determine the safety and preliminary efficacy of oral TQ Formula (TQF), in the treatment of outpatient SARS-CoV-2. In a double-blind, placebo-controlled phase 2 trial, we randomly assigned (1:1 ratio) non-hospitalized, adult (>18 years), symptomatic SARS-CoV-2 patients to receive oral TQF or placebo. The primary endpoints were safety and the median time-to-sustained-clinical-response (SCR). SCR was 6 days in the TQF arm vs. 8 days in the placebo arm (p = 0.77), and 5 days in the TQF arm vs. 7.5 days in the placebo arm in the high-risk cohort, HR 1.55 (95% CI: 0.70, 3.43, p = 0.25). No significant difference was found in the rate of AEs (p = 0.16). TQF led to a significantly faster decline in the total symptom burden (TSB) (p < 0.001), and a significant increase in cytotoxic CD8+ (p = 0.042) and helper CD4+ (p = 0.042) central memory T lymphocytes. TQF exhibited an in vitro inhibitory effect on the entry of five SARS-CoV-2 variants. TQF was well-tolerated. While the median time-to-SCR did not reach statistical significance; it was shorter in the TQF arm and preclinical/clinical signals of TQF activity across multiple endpoints were significant. Therefore, a confirmatory study is planned.

Aerococcus urinae: A Rare Cause of Endocarditis Presenting With Acute Stroke.

Aerococcus urinae is a rare organism infrequently isolated from cultures. Mostly known to cause urinary tract infection, it can cause bacteremia leading to severe urosepsis and infective endocarditis. Embolization is frequently reported with Aerococcus urinae endocarditis (AUE); hence, the presentation is highly variable. Sequelae such as various central nervous system manifestations, sepsis, valvular regurgitation with heart failure and even coronary artery involvement have been reported. We report a case of a 58-year-old man with AUE of the aortic valve, severe aortic regurgitation and embolic stroke as a result of embolization from AUE and ultimately required aortic valve replacement. Our case highlights this rare cause of endocarditis and offers insight into the variability of patient presentation and risk factors to consider.

Piling Gold in the Prostate.

Radiation beams precisely directed at a tumor can attenuate the radiation to contiguous tissues. Image-guided radiation therapy using fiducials allows accurate delineation of tumor location. Traditionally, fiducials in the prostate have been placed by urologists or radiation oncologists. With the evolution of endoscopic ultrasound (EUS), fiducials have been successfully placed under the EUS guidance in different organs. In this case series, fiducials were placed in 3 patients with prostate cancer. All patients completed their radiation therapy, and no complications were reported except mild dysuria in one case. EUS-guided fiducial placement is safe and offers a new modality for fiducial placement in the prostate.

Trastuzumab-Induced Cardiomyopathy and Intermittent Left Bundle Branch Block.

Trastuzumab-induced cardiomyopathy is a known complication of its use in breast cancer treatment, but it remains mostly asymptomatic and often reversible. Non-myopathic cardiac complications have been rarely reported with trastuzumab. These include left and right bundle branch block, arrhythmias and sinus node dysfunction. We report a case of a 52-year-old female breast cancer patient with trastuzumab-induced asymptomatic intermittent left bundle branch block recurring nearly a year after the initial diagnosis and resolution of trastuzumab-related cardiomyopathy.
