Breast cancer is a common malignancy and a common cause of cancer-related mortality in women. Pre-treatment workup of breast cancer does not routinely include positron emission tomography scans. We aimed to review cases of women with breast cancer and a synchronous second primary malignancy. We present three cases of women with non-metastatic cancer in whom a synchronous second primary malignancy was found. Synchronous, second primary malignancies which were identified included rectal cancer, gastrointestinal stromal tumor, and non-small cell lung cancer. All second primary malignancies were identified by a PET-CT scan. In conclusion, PET-CT may be used for detection of secondary primary malignancies in select breast cancer patients.
Background and Objective: Liver enzyme abnormalities (LEA) are extremely common and sometimes severe in individuals infected with human immunodeficiency virus (HIV), but data for this disorder are lacking in the developing countries. The objective of this study was to identify factors associated with LEA in HIV–hepatitis B virus (HBV)/hepatitis C virus (HCV) co-infected patients in Kinshasa, Democratic Republic of the Congo.
Methods: This cross-sectional analytical study included 180 people living with HIV (PLWHIV) mono-infected or co-infected with HBV/HCV between November 10, 2013 and January 10, 2014 in Kinshasa. Sociodemographic, clinical, biological, serological, and immunological data were analyzed. Levels of serum glutamate oxaloacetate transferase (SGOT) and serum glutamate pyruvate transaminase (SGPT) were determined. Antibody levels were determined using enzyme-linked immunosorbent assay (ELISA).
Results: The mean age of patients was 44.2±11.0 years; female sex was predominant (76.7%). Co-infection, mainly with HBV, but also HCV, was found in 43 (23.9%) patients. Elevated liver enzymes were found in 77 (42.8%) of the patients. No difference was found in the rate of liver enzyme abnormalities between patients with HIV mono-infection or HIV co-infection (46.7% versus 30.2%, respectively; P=0.08). Factors associated with LEA were age ≥50 years (adjusted odds ratio [OR] 2.7; 95% CI 1.4–5.5), duration of HIV infection >3 years (adjusted OR 2.7; 95% CI 1.4–5.5), and CD4 count ≤303 cells/mm³ (adjusted OR 2.2; 95% CI 1.1–4.5).
Conclusions: Liver enzyme abnormalities are frequent in patients co-infected with HIV–HBV/HCV as well as in HIV patients without co-infection. Diagnosis is determined based on age, immunodeficiency, and length of illness.
Background: Transthyretin (TTR), also known as prealbumin, has been suggested as an indicator of protein and nutritional status.
Objective: The aim of this study was to examine the maternal and umbilical cord (UC) TTR in relation to intrauterine growth, and the serum TTR of preterm infants in relation to nutritional status and growth.
Methods: After application of exclusion criteria, 49 preterm infants (mean gestational age and birth-weight 32.9±2.9 weeks and 1822±556 g) were included in the study. Transthyretin was sampled at birth and on days 14, 28 or at discharge with growth parameters and nutritional laboratories.
Results: Mean UC and maternal TTR were positively correlated (8.5±2.4 mg/dL and 20.4±7.0 mg/dL, r=0.31, P=0.07). Umbilical cord TTR was neither an index of maturity nor of intrauterine growth. Umbilical cord TTR was higher in females (9.4±2.6 versus 7.6±1.8 mg/dL, P=0.015). Maternal TTR was lower in twin pregnancies (16.8±4.9 versus 22.5±7.3 mg/dL, P=0.007). Although TTR levels gradually increased over time in correlation with post-menstrual and chronological ages (r=0.24, P=0.011 and r=0.40, P<0.001, respectively), there was no correlation to weight gain (r=0.10, P=0.41), nutritional status, protein intake, or laboratories. The only significant correlations were between TTR and glucose and triglycerides levels (r=0.51, P<0.001 for both).
Conclusions: Although TTR levels increased over time, we could not demonstrate significant correlations between TTR and indices of the nutritional status in preterm infants at birth or during the neonatal course.
External accreditation reviews of undergraduate medical curricula play an important role in their quality assurance. However, these reviews occur only at 4–10-year intervals and are not optimal for the immediate identification of problems related to teaching. Therefore, the Standards of Medical Education in Israel require medical schools to engage in continuous, ongoing monitoring of their teaching programs for
compliance with accreditation standards. In this paper, we propose the following: (1) this monitoring be assigned to independent medical education units (MEUs), rather than to an infrastructure of the dean’s office, and such MEUs to be part of the school governance and draw their authority from university institu¬tions; and (2) the differences in the importance of the accreditation standards be addressed by discerning between the “most important” standards that have been shown to improve student well-being and/or patient health outcomes; “important” standards associated with student learning and/or performance; “possibly important” standards with face validity or conflicting evidence for validity; and “least important” standards that may lead to undesirable consequences. According to this proposal, MEUs will evolve into entities dedicated to ongoing monitoring of the education program for compliance with accreditation standards, with an authority to implement interventions. Hopefully, this will provide MEUs and faculty with the common purpose of meeting accreditation requirements, and an agreed-upon prioritization of accreditation standards will improve their communication and recommendations to faculty.
Introduction: The second wave of coronavirus disease 2019 (COVID-19) led to the resurgence of opportunistic infections due to the injudicious use of steroids. Sinonasal mucormycosis was declared an epidemic in India during the pandemic. Mucormycosis was managed effectively by surgical debridement along with systemic amphotericin B. Currently, a resurgence of mucormycosis following initial treatment, in the form of fungal osteomyelitis of the frontal bone, is being seen in India.
Methods: This prospective study included 10 patients with fungal osteomyelitis of the frontal bone due to mucormycosis. All patients underwent surgical debridement of the sequestrum and involucrum, with systemic antifungal pharmacotherapy.
Results: The average duration of time until mucormycosis recurrence was 22 days following initial treatment (range 10–33 days). Patients presented with extracranial bossing following outer frontal cortex erosion (n=3), bicortical erosion (n=3), bifrontal involvement (n=2), dural involvement (n=3), and involvement of the brain parenchyma and prefrontal cortex (n=2). All cases underwent debridement of the entire sequestrous bone and involucrum until normal bone could be identified. The mean admission duration was 4 weeks (range 3–6 weeks). All treated patients are currently alive and without disease, confirmed by contrast-enhanced computed tomography.
Conclusion: Based on our experience, the successful treatment of fungal osteomyelitis due to mucormycosis requires a four-pronged approach: early detection, multidisciplinary management of comorbidities, surgical debridement of necrotic bone, and adequate systemic antifungal therapy.
Objective: Cirrhotic cardiomyopathy (CCM) is associated with increased morbidity and mortality in patients with liver cirrhosis. Yet, it remains an under-diagnosed entity. Further, its relation to the severity of cirrhosis is contradictory. We conducted this study on an Indian population to determine the cardiac dysfunctions in cirrhosis of the liver and correlations with etiologies and cirrhosis severity.
Methods: This study enrolled patients with diagnosed liver cirrhosis without any cardiac disease or conditions affecting cardiac function. All participants were evaluated clinically, electrocardiographically, and echocardiographically. Cirrhosis severity was assessed by scores from the Model for End-stage Liver Disease (MELD) and Child–Turcotte–Pugh (CTP) tests. Cirrhotic cardiomyopathy was defined as diastolic dysfunction and/or systolic dysfunction with QT prolongation.
Results: Ninety-six patients were evaluated, and CTP-A stage of cirrhosis was found in 23 (24%), CTP-B in 42 (43.8%), and CTP-C in 31 (32.3%) cases. Systolic dysfunction was most frequent (P=0.014), and left ventricular ejection fraction was significantly reduced (P=0.001) in CTP-C stage of cirrhosis. Cirrhotic cardiomyopathy was found in 39.6% (n=38) of patients; CCM patients had significantly higher CTP scores (9.6±2.6 versus 8.3±2.3, P=0.012) as well as MELD scores (19.72±4.9 versus 17.41±4.1, P=0.015) in comparison to patients without CCM.
Conclusion: Cirrhotic cardiomyopathy has a positive relationship with the severity of cirrhosis. Systolic function declines with the severity of cirrhosis, and overt systolic dysfunction can be present, particularly in the advanced stage of cirrhosis of the liver.
Background: Blunt traumatic brain injury (bTBI) and uncontrolled hemorrhagic shock (UCHS) are common causes of mortality in polytrauma. We studied the influence of fresh frozen plasma (FFP) resuscitation in a rat model with both bTBI and UCHS before achieving hemorrhage control.
Methods: The bTBI was induced by an external weight drop (200 g) onto the bare skull of anesthetized male Lewis (Lew/SdNHsd) rats; UCHS was induced by resection of two-thirds of the rats’ tails. Fifteen minutes following trauma, bTBI+UCHS rats underwent resuscitation with FFP or lactated Ringer’s solution (LR). Eight groups were evaluated: (1) Sham; (2) bTBI; (3) UCHS; (4) UCHS+FFP; (5) UCHS+LR; (6) bTBI+UCHS; (7) bTBI+UCHS+FFP; and (8) bTBI+UCHS+LR. Bleeding volume, hematocrit, lactate, mean arterial pressure (MAP), heart rate, and mortality were measured.
Results: The study included 97 rats that survived the immediate trauma. Mean blood loss up to the start of resuscitation was similar among UCHS only and bTBI+UCHS rats (P=0.361). Following resuscitation, bleeding was more extensive in bTBI+UCHS+FFP rats (5.2 mL, 95% confidence interval [CI] 3.7, 6.6) than in bTBI+UCHS+LR rats (2.5 mL, 95% CI 1.2, 3.8) and bTBI+UCHS rats (1.9 mL, 95% CI -0.2, 3.9) (P=0.005). Similarly, non-significant increases in blood loss were observed in UCHS+FFP rats (P=0.254). Overall mortality increased if bleeding was above 4.5 mL (92.3% versus 8%; P<0.001). Mortality was 83.3% (10/12) in bTBI+UCHS+FFP rats, 41.7% (5/12) in bTBI+UCHS+LR rats, and 64.3% (9/14) in bTBI+UCHS rats.
Conclusion: The bTBI did not exacerbate bleeding in rats undergoing UCHS. Compared to LR, FFP resuscitation was associated with a significantly increased blood loss in bTBI+UCHS rats.
Xenotransplantation represents a viable solution to meet the great need to provide organ donors at a time when there are not enough human organ donors. A lot of clinical studies have focused on using genetically engineered pigs as the prime source for organ transplantation. However, several religions, such as Judaism and Islam, have restrictions on the use of pigs for food or in business. In this article, we review the Jewish perspectives on xenotransplantation. Overall, the preservation of human life trumps most of the potential religious concerns associated with xenotransplantation. However, there are religious nuances related to xenotransplantation that are highlighted here, and that must be addressed by rabbinical scholars.
Bite mark analysis plays a pivotal role in forensic investigations, by helping to identify suspects and establish links between individuals and crime scenes. However, traditional bite mark methodologies face significant challenges due to issues with reliability and subjectivity. Recent advances in microbiome analysis, which involves identifying and characterizing the microbial communities found in bite marks, have led to the emergence of a promising tool for forensic investigations. The integration of microbiome analysis with conventional DNA profiling enables more accurate interpretation of bite mark evidence in forensic investigations. This review provides an in-depth look at the integration of bite mark microbiome analysis with forensic DNA profiling. It also addresses the challenges and strategies involved in microbiome-based bite mark analysis for forensic purposes.
Pancytopenia is defined as a reduction in red blood cells, white blood cells, and platelets, and can pose as a diagnostic challenge due to the multitude of causes. Myxedema coma is the manifestation of severe untreated hypothyroidism. This case report presents a rare instance of myxedema coma-associated pancytopenia in a 53-year-old man with a history of untreated hypothyroidism. The patient presented with altered mental status and vital instability, and on further workup was found to have pancytopenia. During his hospital stay his symptomatic hypothyroidism was identified, and he was treated with intravenous levothyroxine, hydrocortisone, and supportive care. The patient’s clinical status improved gradually, with normalized blood counts upon discharge. This case underscores the significance of considering myxedema coma in the differential diagnosis of pancytopenia, especially in older patients with limited healthcare access. Increased awareness of this association can aid clinicians in timely diagnosis and management, preventing potential complications associated with untreated hypothyroidism.
