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.

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.

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.

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.

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.

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.

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.

Epstein-Barr-positive classical Hodgkin lymphoma-associated haemophagocytic lymphohistocytiosis: a rare case.

Haemophagocytic lymphohistiocytosis (HLH) is a life-threatening condition, which is usually triggered by autoimmune disorders, viral infections and malignancy, like lymphomas. We present a 60-year-old Hispanic woman with a medical history of hypertension and systemic lupus erythematosus presenting with fever, generalised weakness and shortness of breath for 3 weeks. She was hypotensive on presentation, and a CT scan of abdomen/chest showed multiple irregular hepatic and splenic hypodense lesions. A liver biopsy revealed Classical Hodgkin lymphoma (cHL) with positive Epstein-Barr virus (EBV) staining that was later confirmed with high serum EBV DNA levels. Incidentally, a liver biopsy disclosed haemophagocytosis in some cells. HLH-associated cHL is an uncommon condition that can cause severe systemic symptoms acting as the perfect mimic of septic shock, deviating the clinical eye toward treating with antibiotics and not addressing in a timely manner the real aetiology of the patient's condition.

Disseminated Coccidioidomycosis Presenting as Carcinomatosis Peritonei and Intestinal Coccidioidomycosis in a Patient with HIV.

Coccidioidomycosis (CM) is a fungal infection endemic in southwestern regions of the United States, northwestern regions of Mexico, and some areas of Brazil and Argentina. Clinical presentation varies depending on the extent of the infection and the immune status of the host. The most common presentation ranges from flu-like symptoms to self-limiting pneumonia. Extrapulmonary presentations are uncommon and may involve the meninges, skin, and bone. Gastrointestinal and peritoneal involvement is extremely rare. Here we report a case of disseminated CM presenting as carcinomatosis peritonei as an AIDS-defining illness in a young male.

Winning Hearts and Minds: Inspiring Medical Students into Cardiothoracic Surgery Through Highly Interactive Workshops.

BACKGROUND: The cardiothoracic surgical (CTS) specialty has witnessed a decline in the applicant pool. Early exposure, positive experiences, inspiring role models, and career insight are key in the decision-making process for specialty choice. Our objective was to assess the effect of high tutor:student ratio interactive CTS workshops in influencing the career choice of UK undergraduate medical students. METHODS: Medical students attended a workshop comprising (1) guided dissection of fresh animal hearts, (2) surgical skills practice on models and fresh hearts, (3) operative videos (adult, congenital, transplant, and aortic) with interactive commentary, and (4) careers seminar. The tutor:student ratio was very high (between 3-1 and 5-1). A questionnaire was completed at the end of each workshop to assess its effect, including a 10-point Likert scale on the perceived attraction to CTS before and after the workshop. RESULTS: A total of 96 delegates attended 5 workshops in 3 UK medical schools. Response rate was 83% from 80 undergraduate students. In all, 58% were male (46/80). There was an equal proportion of sexes in the early years of medical school, but was significantly skewed toward male in the later years. There was a statistically significant increase of 2.1 (standard deviation [SD] = 1.5) in the Likert scores before (µ = 5.0, SD = 2.1) and after (µ = 7.1, SD = 1.9) (p = 0.001). This represents a 42% increase in the perceived attraction to the CTS specialty because of the workshops. CONCLUSIONS: Our workshops have a significant effect in stimulating undergraduate medical students toward a career in cardiothoracic surgery. We encourage national take-up of these easily organized daylong workshops to foster interest in the next generation of cardiothoracic surgeons.

Pseudozyma spp catheter-associated blood stream infection, an emerging pathogen and brief literature review.

Pseudozyma spp are amorphic yeasts. They are commonly plant pathogens, but rarely cause invasive fungal disease in humans. Only three cases of central venous catheter (CVC)-associated blood stream infections due to this organism have been reported in the literature. Main underlying risk factors for Pseudozyma spp infection are bowel surgery, CVC and total parenteral nutrition. We present a rare case of Pseudozyma spp catheter-associated blood stream infection that was successfully treated with antifungal therapy and removal of CVC. It is important to recognise and differentiate this species from other yeasts as it may require the use of amphotericin B or voriconazole instead of fluconazole, to which the organism is variably resistant.

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.

Heart valve surgery: EuroSCORE vs. EuroSCORE II vs. Society of Thoracic Surgeons score.

BACKGROUND: This is a validation study comparing the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II with the previous additive (AES) and logistic EuroSCORE (LES) and the Society of Thoracic Surgeons' (STS) risk prediction algorithm, for patients undergoing valve replacement with or without bypass in Pakistan. PATIENTS AND METHODS: Clinical data of 576 patients undergoing valve replacement surgery between 2006 and 2013 were retrospectively collected and individual expected risks of death were calculated by all four risk prediction algorithms. Performance of these risk algorithms was evaluated in terms of discrimination and calibration. RESULTS: There were 28 deaths (4.8%) among 576 patients, which was lower than the predicted mortality of 5.16%, 6.96% and 4.94% by AES, LES and EuroSCORE II but was higher than 2.13% predicted by STS scoring system. For single and double valve replacement procedures, EuroSCORE II was the best predictor of mortality with highest Hosmer and Lemmeshow test (H-L) p value (0.346 to 0.689) and area under the receiver operating characteristic (ROC) curve (0.637 to 0.898). For valve plus concomitant coronary artery bypass grafting (CABG) patients actual mortality was 1.88%. STS calculator came out to be the best predictor of mortality for this subgroup with H-L p value (0.480 to 0.884) and ROC (0.657 to 0.775). CONCLUSIONS: For Pakistani population EuroSCORE II is an accurate predictor for individual operative risk in patients undergoing isolated valve surgery, whereas STS performs better in the valve plus CABG group.

Colorectal cancers from distinct ancestral populations show variations in BRAF mutation frequency.

It has been demonstrated for some cancers that the frequency of somatic oncogenic mutations may vary in ancestral populations. To determine whether key driver alterations might occur at different frequencies in colorectal cancer, we applied a high-throughput genotyping platform (OncoMap) to query 385 mutations across 33 known cancer genes in colorectal cancer DNA from 83 Asian, 149 Black and 195 White patients. We found that Asian patients had fewer canonical oncogenic mutations in the genes tested (60% vs Black 79% (P = 0.011) and White 77% (P = 0.015)), and that BRAF mutations occurred at a higher frequency in White patients (17% vs Asian 4% (P = 0.004) and Black 7% (P = 0.014)). These results suggest that the use of genomic approaches to elucidate the different ancestral determinants harbored by patient populations may help to more precisely and effectively treat colorectal cancer.

Delayed-onset endophthalmitis associated with Ex-PRESS mini glaucoma shunt®.

The authors describe a 92-year-old man who developed delayed-onset endophthalmitis secondary to Bacillus sp. in his left eye 3 years after placement of an Ex-PRESS mini glaucoma shunt (Optonol Ltd., Neve Ilan, Israel). Seidel testing was positive over the Ex-PRESS mini glaucoma shunt. The patient underwent vitreous tap followed by intravitreal injections of vancomycin (1 mg/0.1 mL), ceftazadime (2.25 mg/0.1 mL), and dexamethasone (0.4 mg/0.1 mL), along with subconjunctival injection of vancomycin and tobramycin. The last recorded visual acuity was 3/200 in the left eye. With a 1-month follow-up, this case illustrates successful treatment with a vitreous tap and injection of intravitreal antibiotics. Vitrectomy and removal of the Ex-PRESS mini glaucoma shunt were not performed.
