The Epidemiology and Clinical Presentation of Pancreatic Divisum: A Case Series of 57 Case Reports.

OBJECTIVES: Pancreatic divisum (PD) is the second most common congenital abnormality of the pancreatic duct, which affects 2% to 3% of the population. Most of the population remains asymptomatic, but in people who present with symptoms, it can be a cause of anguish and should be recognized. The main goal of this article was to provide a comprehensive picture of clinical and epidemiological methods of diagnosis and treatment of PD. METHODS: A total of 57 PD case reports were considered in this descriptive analysis with 51 case reports and case series published within the last 25 years. The search strategies include systemic searches using scholarly search engines such as Medscape, Scopus, Cochrane, and PubMed. RESULTS: The 57 cases we studied have an average age of presentation of 42 years, with female sex (58%) predominance. Common presenting symptoms were abdominal pain (87.72%) and radiation to the back (21.6%). Eighty-one percent of the case studies reported pancreatitis, and 63.2% had recurrent pancreatitis. At presentation, laboratory values demonstrated increased amylase, lipase, and liver enzymes. PD was diagnosed using magnetic resonance cholangiopancreatography (28.1%), endoscopic retrograde cholangiopancreatography (57.9%), endoscopic ultrasound (7%), or computed tomography (5.3%) scan of the abdomen. Of significance, biliary duct dilation was found in 70.6% of patients diagnosed as having PD. Incidental masses were found in 66.7% of the patients. The most successful treatment was sphincterotomy with or without stents (47.6%), followed by pancreatoduodenectomy (19%) and pancreaticojejunostomy (10%). CONCLUSIONS: Physicians managing pancreatitis should add PD to their differential diagnoses because it will help improve patient outcomes and avoid unfavorable consequences.

Optical photothermal infrared spectroscopy and discrete wavenumber imaging for high content screening of single cells.

Major drawbacks of direct mid-infrared spectroscopic imaging of single cells in an aqueous buffer are strong water absorption, low resolution typically above 10 µm, and Mie scattering effects. This study demonstrates how an indirect detection principle can overcome these drawbacks using the optical photothermal infrared (O-PTIR) technique for high-resolution discrete wavenumber imaging and fingerprint spectroscopy of cultivated cells as a model system in a simple liquid sample chamber. The O-PTIR spectra of six leukemia- and cancer-derived cell lines showed main IR bands near 1648, 1547, 1447, 1400, 1220, and 1088 cm-1. Five spectra of approximately 260 single cells per cell type were averaged, the O-PTIR data set was divided into leukemia-derived cells (THP-1, HL 60, Jurkat, and Raji) and cancer cells (HeLa and HepaRG), and partial least squares linear discriminant analysis (PLS-LDA) was applied in the spectral range 800-1800 cm-1 to train three classification models. A leukemia versus cancer cell model showed an accuracy of 90.0%, the HeLa versus HepaRG cell model had an accuracy of 95.4%, and the model for the distinction of leukemia cells had an accuracy of 75.4%. IR bands in linear discriminants (LDs) of the models were correlated with second derivative spectra that resolved more than 25 subbands. The IR and second derivative spectra of proteins, DNA, RNA and lipids were collected as references to confirm band assignments. O-PTIR images of single cells at a 200 nm step size were acquired at 1086, 1548, and 1746 cm-1 to visualize the nucleic acid, protein, and lipid distribution, respectively. Variations in subcellular features and in the lipid-to-protein and nucleic acid-to-protein ratios were identified that were consistent with biomolecular information in LDs. In conclusion, O-PTIR can provide high-quality spectra and images with submicron resolution of single cells in aqueous buffers that offer prospects in high-content screening applications.

Investigating biochemical and structural changes of glycated collagen using multimodal multiphoton imaging, Raman spectroscopy, and atomic force microscopy.

Advanced glycation end products (AGEs) form extracellular crosslinking with collagenous proteins, which contributes to the development of diabetic complications. In this study, AGEs-related pentosidine (PENT) crosslinks-induced structural and biochemical changes are studied using multimodal multiphoton imaging, Raman spectroscopy and atomic force microscopy (AFM). Decellularized equine pericardium (EP) was glycated with four ribose concentrations ranging between 5 and 200 mM and monitored for up to 30 days. Two-photon excited fluorescence (TPEF) and second harmonic generation (SHG) microscopic imaging probed elastin and collagen fibers, respectively. The glycated EP showed a decrease in the SHG intensities associated with loss of non-centrosymmetry of collagen and an increase of TPEF intensities associated with PENT crosslinks upon glycation. TPEF signals from elastin fibers were unaffected. A three-dimensional reconstruction with SHG + TPEF z-stack images visualized the distribution of collagen and elastin within the EP volume matrix. In addition, Raman spectroscopy (RS) detected changes in collagen-related bands and discriminated glycated from untreated EP. Furthermore, AFM scans showed that the roughness increases and the D-unit structure of fibers remained unchanged during glycation. The PENT crosslinked-induced changes are discussed in the context of previous studies of glutaraldehyde- and genipin-induced crosslinking and collagenase-induced digestion of collagen. We conclude that TPEF, SHG, RS, and AFM are effective, label-free, and non-destructive methods to investigate glycated tissues, differentiate crosslinking processes, and characterize general collagen-associated and disease-related changes, in particular by their RS fingerprints.

Structural and Biochemical Changes in Pericardium upon Genipin Cross-Linking Investigated Using Nondestructive and Label-Free Imaging Techniques.

Tissue cross-linking represents an important and often used technique to enhance the mechanical properties of biomaterials. For the first time, we investigated biochemical and structural properties of genipin (GE) cross-linked equine pericardium (EP) using optical imaging techniques in tandem with quantitative atomic force microscopy (AFM). EP was cross-linked with GE at 37 °C, and its biochemical and biomechanical properties were observed at various time points up to 24 h. GE cross-linked EP was monitored by the normalized ratio between its second-harmonic generation (SHG) and two-photon autofluorescence emissions and remained unchanged for untreated EP; however, a decreasing ratio due to depleted SHG and elevated autofluorescence and a fluorescence band at 625 nm were found for GE cross-linked EP. The mean autofluorescence lifetime of GE cross-linked EP also decreased. The biochemical signature of GE cross-linker and shift in collagen bands were detected and quantified using shifted excitation Raman difference spectroscopy as an innovative approach for tackling artifacts with high fluorescence backgrounds. AFM images indicated a higher and increasing Young's modulus correlated with cross-linking, as well as collagen structural changes in GE cross-linked EP, qualitatively explaining the observed decrease in the second-harmonic signal. In conclusion, we obtained detailed information about the biochemical, structural, and biomechanical effects of GE cross-linked EP using a unique combination of optical and force microscopy techniques in a nondestructive and label-free manner.

Monitoring Changes in Biochemical and Biomechanical Properties of Collagenous Tissues Using Label-Free and Nondestructive Optical Imaging Techniques.

We demonstrate the ability of nondestructive optical imaging techniques such as second-harmonic generation (SHG), two-photon fluorescence (TPF), fluorescence lifetime imaging (FLIM), and Raman spectroscopy (RS) to monitor biochemical and mechanical alterations in tissues upon collagen degradation. Decellularized equine pericardium (EP) was treated with 50 µg/mL bacterial collagenase at 37 °C for 8, 16, 24, and 32 h. The SHG ratio (defined as the normalized ratio between SHG and TPF signals) remained unchanged for untreated EP (stored in phosphate-buffered solution (PBS)), whereas treated EP showed a trend of a decreasing SHG ratio with increasing collagen degradation. In the fluorescence domain, treated EP experienced a red-shifted emission and the fluorescence lifetime had a trend of decreasing lifetime with increasing collagen digestion. RS monitors collagen degradation, the spectra had less intense Raman bands at 814, 852, 938, 1242, and 1270 cm-1. Non-negative least-squares (NNLS) modeling quantifies collagen loss and relative increase of elastin. The Young's modulus, derived from atomic force microscope-based nanoindentation experiments, showed a rapid decrease within the first 8 h of collagen degradation, whereas more gradual changes were observed for optical modalities. We conclude that optical imaging techniques like SHG, RS, and FLIM can monitor collagen degradation in a label-free manner and coarsely access mechanical properties in a nondestructive manner.

Assessment of shifted excitation Raman difference spectroscopy in highly fluorescent biological samples.

Shifted excitation Raman difference spectroscopy (SERDS) can be used as an instrumental baseline correction technique to retrieve Raman bands in highly fluorescent samples. Genipin (GE) cross-linked equine pericardium (EP) was used as a model system since a blue pigment is formed upon cross-linking, which results in a strong fluorescent background in the Raman spectra. EP was cross-linked with 0.25% GE solution for 0.5 h, 2 h, 4 h, 6 h, 12 h, and 24 h, and compared with corresponding untreated EP. Raman spectra were collected with three different excitation wavelengths. For the assessment of the SERDS technique, the preprocessed SERDS spectra of two excitation wavelengths (784 nm-786 nm) were compared with the mathematical baseline-corrected Raman spectra at 785 nm excitation using extended multiplicative signal correction, rubberband, the sensitive nonlinear iterative peak and polynomial fitting algorithms. Whereas each baseline correction gave poor quality spectra beyond 6 h GE crosslinking with wave-like artefacts, the SERDS technique resulted in difference spectra, that gave superior reconstructed spectra with clear collagen and resonance enhanced GE pigment bands with lower standard deviation. Key for this progress was an advanced difference optimization approach that is described here. Furthermore, the results of the SERDS technique were independent of the intensity calibration because the system transfer response was compensated by calculating the difference spectrum. We conclude that this SERDS strategy can be transferred to Raman studies on biological and non-biological samples with a strong fluorescence background at 785 nm and also shorter excitation wavelengths which benefit from more intense scattering intensities and higher quantum efficiencies of CCD detectors.

FLIm-Guided Raman Imaging to Study Cross-Linking and Calcification of Bovine Pericardium.

Bovine pericardium (BP) is a vascular biomaterial used in cardiovascular surgery that is typically cross-linked for masking antigenicity and enhance stability. There is a need for biochemical evaluation of the tissue properties prior to implantation to ensure that quality and reliability standards are met. Here, engineered antigen removed BP (ARBP) that was cross-linked with 0.2% and 0.6% glutaraldehyde (GA), and further calcified in vitro to simulate graft calcifications upon implantation was characterized nondestructively using fluorescence lifetime imaging (FLIm) to identify regions of interest which were then assessed by Raman spectroscopy. We observed that the tissue fluorescence lifetime shortened, and that Raman bands at 856, 935, 1282, and 1682 cm-1 decreased, and at 1032 and 1627 cm-1 increased with increasing GA cross-linking. Independent classification analysis based on fluorescence lifetime and on Raman spectra discriminated between GA-ARBP and untreated ARBP with an accuracy of 91% and 66%, respectively. Pearson's correlation analysis showed a strong correlation between pyridinium cross-links measured with high-performance liquid chromatography and fluorescence lifetime measured at 380-400 nm (R = -0.76, p = 0.00094), as well as Raman bands at 856 cm-1 for hydroxy-proline (R = -0.68, p = 0.0056) and at 1032 cm-1 for hydroxy-pyridinium (R = 0.74, p = 0.0016). Calcified areas of GA cross-linked tissue showed characteristic hydroxyapatite (959 and 1038 cm-1) bands in the Raman spectrum and fluorescence lifetime shortened by 0.4 ns compared to uncalcified regions. FLIm-guided Raman imaging could rapidly identify degrees of cross-linking and detected calcified regions with high chemical specificity, an ability that can be used to monitor tissue engineering processes for applications in regenerative medicine.

FLIm and Raman Spectroscopy for Investigating Biochemical Changes of Bovine Pericardium upon Genipin Cross-Linking.

Biomaterials used in tissue engineering and regenerative medicine applications benefit from longitudinal monitoring in a non-destructive manner. Label-free imaging based on fluorescence lifetime imaging (FLIm) and Raman spectroscopy were used to monitor the degree of genipin (GE) cross-linking of antigen-removed bovine pericardium (ARBP) at three incubation time points (0.5, 1.0, and 2.5 h). Fluorescence lifetime decreased and the emission spectrum redshifted compared to that of uncross-linked ARBP. The Raman signature of GE-ARBP was resonance-enhanced due to the GE cross-linker that generated new Raman bands at 1165, 1326, 1350, 1380, 1402, 1470, 1506, 1535, 1574, 1630, 1728, and 1741 cm-1. These were validated through density functional theory calculations as cross-linker-specific bands. A multivariate multiple regression model was developed to enhance the biochemical specificity of FLIm parameters fluorescence intensity ratio (R2 = 0.92) and lifetime (R2 = 0.94)) with Raman spectral results. FLIm and Raman spectroscopy detected biochemical changes occurring in the collagenous tissue during the cross-linking process that were characterized by the formation of a blue pigment which affected the tissue fluorescence and scattering properties. In conclusion, FLIm parameters and Raman spectroscopy were used to monitor the degree of cross-linking non-destructively.

The cardio-oncology continuum: Bridging the gap between cancer and cardiovascular care.

Cancer and cardiovascular disease are two of the leading causes of death worldwide. Although cancer has historically been viewed as a condition characterized by abnormal cell growth and proliferation, it is now recognized that cancer can lead to a variety of cardiovascular diseases. This is due to the direct impact of cancer on the heart and blood vessels, which can cause myocarditis, pericarditis, and vasculitis. Additionally, cancer patients frequently experience systemic effects such as oxidative stress, inflammation, and metabolic dysregulation, which can contribute to the development of cardiovascular risk factors such as hypertension, dyslipidemia, and insulin resistance. It is important to closely monitor patients with cancer, especially those undergoing chemotherapy or radiation therapy, for cardiovascular risk factors and promptly address them. This article aims to explore the clinical implications of the underlying mechanisms connecting cancer and cardiovascular diseases. Our analysis highlights the need for improved cooperation between oncologists and cardiologists, and specialized treatment for cancer survivors.

A comprehensive analysis of different types of clinical rounds in hospital medicine.

Table rounds and bedside rounds are two methods healthcare professionals employ during clinical rounds for patient care and medical education. Bedside rounds involve direct patient engagement and physical examination, thus significantly impacting patient outcomes, such as improving communication and patient satisfaction. Table rounds occur in a conference room without the patient present and involve discussing patient data, which is more effective in fostering structured medical education. Both bedside and table rounds have pros and cons, and healthcare professionals should consider the specific requirements of their patients and medical trainees when deciding which approach to use. This research utilized a comprehensive search to identify relevant resources, such as university website links, as well as a PubMed search using relevant keywords such as 'bedside rounding,' 'table rounding,' and 'patient satisfaction.' Relevance, publication date, and study design were the basis for inclusion criteria. This study compared the effectiveness of these two methods based on physician communication, medical education, patient care, and patient satisfaction.

Cardiovascular Challenges Beyond Earth: Investigating the Impact of Space Travel on Astronauts' Cardiovascular Health.

In the coming decades, as humanity aims to establish a presence on Mars, there is a growing significance in comprehending, monitoring, and controlling the diverse health challenges arising from space exploration. The extended exposure to microgravity during space missions leads to various physical alterations in astronauts, such as shifts in bodily fluids, reduced plasma volume, loss of bone density, muscle wasting, and cardiovascular deconditioning. These changes can ultimately lead to orthostatic intolerance, underscoring the increasing importance of addressing these health risks. Astronauts are exposed to cosmic radiation consisting of high-energy particles from various sources, including solar cosmic rays and galactic cosmic rays. These radiations can impact the electrical signals in the heart, potentially causing irregular heart rhythms. Understanding the risks to the heart and blood circulation brought on by exposure to space radiation and the overall stress of spaceflight is essential and this article reviews the cardiovascular effects of space travel on astronauts.

Lab testing overload: a comprehensive analysis of overutilization in hospital-based settings.

Overuse of laboratory tests has been a growing problem in the inpatient hospital setting for years, which adds to the rising cost of care. Various factors come into play, such as clinical routines, lack of cost transparency, and the convenience of electronic health record-based ordering. The financial ramifications of the overuse are significant, as lab costs drive most medical decisions. Eliminating unnecessary testing with clinical decision support and best practices is associated with marked cost savings, improved outcomes, and decreased patient distress. The excessive use of laboratory tests highly affects patients, resulting in hospital-induced anemia, low patient satisfaction, and poor outcomes. Tackling lab overuse requires a multifaceted approach that includes education, technology, and policy changes. In the era of precision healthcare, optimizing test utilization can reduce costs, decrease waste, and improve patient care.

Navigating the Depths of Cardiovascular Effects on Submariners.

The environment of the submariner is inherently endowed with several health risk factors, namely confinement, inactivity, caloric excess, and circadian disruption, among others, during deployment. Metabolic disturbances, increased cardiovascular risk, and sleep deprivation are associated with interrupting circadian rhythms due to routines contributing to physiological and cognitive abnormalities. Additionally, submariners face vitamin deficits of vitamin D and vitamin B12 due to little exposure to sunlight and poor nutrition. It is associated with cardiovascular dysfunctions, endothelial dysfunctions, metabolic abnormalities, and a greater cardiovascular risk. Moreover, high obesity prevalence has been noted among submariners. Such cases were attributed to leptin resistance, body fat deposits, and lifestyle statistics. Other risk factors to the cardiovascular system, like changes in heart rate variability and heart functions, have been witnessed. These health challenges can be mitigated by adopting proactive steps to address submariners' specific health needs. Such measures should include the prevention of stable circadian rhythms, vitamin intake, lifestyle, and cardiovascular health. By addressing these issues, submariners' well-being will be upheld, and their vulnerability to cardiovascular diseases and other health-related complications will be lessened.

Age-Related Orthostatic Hypotension: A Comprehensive Analysis of Prevalence, Mechanisms, and Management in the Geriatric Population.

Geriatric patients frequently encounter orthostatic hypotension (OH), a multifaceted condition characterized by a significant drop in blood pressure upon assuming an upright position. As the elderly population is particularly susceptible to OH, our review endeavors to comprehensively explore the complex nature of this condition and various factors contributing to its development. We investigate the impact of comorbidities, polypharmacy, age-related physiological changes, and autonomic dysfunction in the pathogenesis of OH. Geriatric patients with OH are faced with an elevated risk of falls, syncope, a decline in their overall quality of life, and hence increased mortality. These implications require careful consideration, necessitating a thorough examination of therapeutic strategies. We evaluate various pharmaceutical and nonpharmacological therapies, delving into the effectiveness and safety of each approach in managing OH within geriatric populations. We explore the role of pharmacotherapy in alleviating symptoms and mitigating OH-related complications, as well as the potential benefits of volume expansion techniques to augment blood volume and stabilize blood pressure. We place particular emphasis on the significance of lifestyle changes and nonpharmacological interventions in enhancing OH management among the elderly. These interventions encompass dietary modifications, regular physical activity, and postural training, all tailored to the unique needs of the individual patient. To optimize outcomes and ensure patient safety, we underscore the importance of individualized treatment plans that take into account the geriatric patient's overall health status, existing comorbidities, and potential interactions with other medications. This review aims to improve clinical practice and patient outcomes by advocating for early detection, properly tailored management, and targeted interventions to address OH in the elderly population. By raising awareness of OH's prevalence and complexities among healthcare professionals, we hope to foster a comprehensive understanding of OH and contribute to the overall wellness and quality of life of this vulnerable demographic.

Effect of Phosphodiesterase-5 (PDE-5) Inhibitors on Clinical Outcomes in Patients With Pulmonary Hypertension: A Meta-Analysis of Randomized Control Trials.

We intended to summarize the most recent research pertaining to the use of phosphodiesterase-5 (PDE5) inhibitors in pulmonary hypertension in light of recent developments in the knowledge of the pathophysiological mechanisms and treatments for pulmonary hypertension, with major contributions in the area in the last decade. The aim of this meta-analysis is to determine the efficacy of PDE5 inhibitors for pulmonary hypertension in adults. We followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines to carry out this meta-analysis. Online database searching to identify eligible trials was performed in MEDLINE, EMBASE, and the Cochrane Library by two authors independently. Outcomes assessed in the current meta-analysis included change in the cardiac index from baseline in liters per minute per square meter (L/min/m2), mean peripheral arterial pressure (PAP) in mm Hg, mortality, hospitalization, and six-minute walking distance (6MWD) in meters (m). Overall, 17 articles met the inclusion criteria and were included in the current meta-analysis. PDE5 inhibitors significantly improve cardiac index (mean difference: 0.18, 95% CI: 0.04, 0.32, p-value: 0.01), mean PAP (mean difference: -5.61, 95% CI: -7.60, -3.62, p-value: 0.01), and 6MWD (mean difference: 26.26, 95% CI: 16.95, 35.57, p-value: 0.001) as compared to the patients in the control group. No significant difference was found in terms of risk of mortality (risk ratio (RR): 0.51, 95% CI: 0.17, 1.54) and risk of hospitalization (RR: 0.59, 95% CI: 0.23, 1.55) between the two groups. The current meta-analysis concluded that PDE5 inhibitors improve 6MWD, mean PAP, and cardiac index in patients with pulmonary hypertension. However, no significant difference was reported in terms of mortality and hospitalization between the two groups.

Comparison of Efficacy and Safety of Low-Dose Versus High-Dose Dexamethasone in Hospitalized COVID-19 Patients: A Meta-Analysis.

The aim of this study is to compare the efficacy and safety of low-dose and high-dose dexamethasone in hospitalized coronavirus disease 2019 (COVID-19) patients. The current meta-analysis was conducted in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was carried out using PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), and Embase. Outcomes assessed in the current meta-analysis included 28-day mortality, intensive care unit (ICU) admission, mechanical ventilation, length of ICU admission (days), and length of hospital stay (days). For safety, we compared hypoglycemia and the incidence of infection between the high-dose dexamethasone group and the low-dose dexamethasone group. A total of four studies fulfilled the inclusion criteria and were included in this meta-analysis. No significant difference was found between the two groups in terms of ICU admission (risk ratio (RR): 0.72, 95% confidence interval (CI): 0.41-1.28, p-value: 0.27), length of stay in ICU in days (mean difference (MD): -0.05, 95%CI: -3.96-3.87, p-value: 0.98, I-square: 94%), length of hospital stay in days (MD: -0.94, 95%CI: -1.94-0.06, p-value: 0.07), need of mechanical ventilation (RR: 0.72, 95%CI: 0.36-1.48, p-value: 0.38), and 28-day mortality (RR: 0.90, 95% CI: 0.50-1.64, p-value: 0.74). The current study showed that higher doses of dexamethasone failed to enhance efficacy compared to low-dose dexamethasone. Thus, based on the findings of this meta-analysis, low-dose dexamethasone can be recommended for these patients.

Asymptomatic Hyperuricemia as an Independent Risk Factor for Myocardial Infarction in Adult Population: A Four-Year Follow-Up Study.

Introduction A condition in which uric acid levels are elevated but there are no accompanying symptoms is known as asymptomatic hyperuricemia. As a result of the disparity in opinions and findings between the studies, the guidelines regarding whether or not asymptomatic hyperuricemia should be treated are unclear. Material and methods Between the months of January 2017 and June 2022, this research was carried out in the community in collaboration with the internal medicine unit and the public health unit of Liaquat University of Medical and Health Sciences. After obtaining informed consent from each participant, the researchers enrolled 1,500 patients in the study who had uric acid levels that were greater than 7.0 mg/dL. These patients ranged in age from 40 to 70 years old and were of either gender. As a control group, 1,500 patients were recruited who did not have abnormally high levels of uric acid. Patients were monitored for a total of 48 months or until the occurrence of a major cardiovascular event (MACCE) or death from all causes, whichever occurred first. Death, cardiovascular mortality, non-fatal myocardial infarction, and non-fatal stroke were the four categories that made up the primary outcome, also known as MACCEs. Results In the hyperuricemic group, the incidence of myocardial infarction that did not result in death was significantly higher than in the non-hyperuricemic group (1.6% vs. 0.7%; p-value, 0.04). However, the result was not significant for deaths from all causes, deaths from cardiovascular disease, or strokes that did not result in death. Conclusion Asymptomatic hyperuricemia is a potential threat to one's health that can lead to cardiovascular diseases and may go undiagnosed in some cases. It is important to remember that hyperuricemia can lead to delirious complications, so efforts should be made to perform routine monitoring and management of the condition.

Coexistence of Cutaneous Squamous Cell Carcinoma and Basal Cell Carcinoma in a Renal Transplant Recipient: A Case Report.

In solid organ transplant patients, non-melanoma skin cancer remains a leading cause of mortality. The most common skin malignancies in solid organ transplant patients are squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). In organ transplant patients, SCC is 100 times more prevalent, and BCC is 10 times more prevalent than in the general population. Many risk factors for developing such malignancies are equivalent to those in the general population. However, in the transplant population, such cancers occur at an earlier age, act more aggressively, and often appear at multiple locations. Thus, assiduousness on the patient's part and healthcare providers is the highest priority. The concurrence of SCC and BCC together is rarely encountered in a post-transplant individual. We report a rare case of coexistence of SCC and BCC in the same patient. A 63-year-old man had been diagnosed with SCC and BCC simultaneously by a punch biopsy performed at two different scalp lesions of different diameters. This review describes an unusual occurrence of both skin cancers concurrently in a kidney transplant recipient.

Retroperitoneal Ancient Neurilemmoma: A Nervous Rarity.

Neurilemmomas are tumors of neural origin that comprise Schwann cell proliferation in a characteristic pattern. They are benign in nature. Ancient neurilemmomas are usually longstanding growths that exhibit degenerative features that could be mistaken for malignancy. We report a case of ancient neurilemmoma in a 70-year-old male patient in the retroperitoneal area. Retroperitoneal schwannomas are extremely uncommon along with ancient neurilemmoma features making it worth reporting.
