The Management of a Urinary Bladder Leak in a Patient with Radiation Cystitis.

Urinary dysfunction following treatment for rectal adenocarcinoma is a common and complex complication. We present a case of a 69-year-old male who underwent laparoscopic-assisted left hemicolectomy and loop ileostomy after receiving chemotherapy and radiation therapy for rectal adenocarcinoma. Postoperatively, it was incidentally discovered the patient had urinary frequency and urgency. Cystoscopy revealed radiation changes to the bladder walls and a bladder leak was confirmed by cystogram. The patient underwent successful repair of the urinary bladder leak, with challenges posed by prior radiation therapy. Effective prevention and management strategies for urinary dysfunction require a comprehensive preoperative risk assessment, consideration of nerve-preserving surgical techniques, and prompt identification and repair of postoperative complications.

A Rare Case of Primary Gastric Signet Ring Cell Carcinoma: a Review of Guidelines for the Management of Gastric Cancer.

Gastric carcinoma is the fifth most common and the third leading cause of cancer deaths worldwide. The incidence of diffuse-type gastric cancer, of which signet ring cell carcinoma is a subtype, is rising in the world. Due to non-specific gastritis-like symptoms, difficulty in assessing true tumor characteristics owing to its horizontal spread, and non-distinguishable endoscopic appearance from other gastric pathologies, the diagnosis of this subtype is challenging. We present a case of a 67-year-old woman with progressively worsening abdominal pain who came for an endoscopic ultrasound evaluation of an incidentally noted pancreatic cyst on a previous MRI. During endoscopy, a 1-cm gastric ulcer was noted along the lesser curvature of the gastric body. Biopsy confirmed a diagnosis of gastric signet ring cell carcinoma (SRCC) with CDX-2 and keratin positivity. The patient underwent total gastrectomy with Roux-en-Y reconstruction. Gross specimen revealed a diffuse SRCC invading the muscularis propria, along with lymphovascular and perineural invasion. In the context of our case, we discuss the morphological features of SRCC and the effectiveness of treatment options based on existing literature. Early accurate diagnosis and staging play an important role in determining treatment options as well as the clinical course of gastric SRCC.

Pyrexia of Unknown Origin: A Report of Two Cases.

Pyrexia of unknown origin (PUO) is a prolonged fever lasting several weeks without an identifiable cause despite extensive medical evaluation. Many a time, its cause remains largely unknown even after collecting a detailed medical history, conducting comprehensive physical assessments, and performing various standard laboratory tests and imaging procedures. This case series presents two cases of pyrexia of unknown origin. The first case includes a unique and uncommon presentation of non-Hodgkin's lymphoma. In the second case, the patient's fever remained unexplained after various investigations and treatments. The two documented cases of PUO presented in this report aim to contribute to the understanding of its diverse etiology and diagnostic challenges. By highlighting unique presentations and diagnostic dilemmas, the cases aim to promote awareness and facilitate timely recognition and appropriate management of PUO.

Amiodarone-Induced Leukocytoclastic Vasculitis in a Decompensated Heart Failure Patient: A Case Report.

Leukocytoclastic vasculitis (LCV) is a small-vessel vasculitis characterized by inflammation and damage to the walls of small blood vessels. It typically presents with palpable purpura and can be associated with various systemic conditions. Although its etiology is diverse, LCV has been associated with systemic diseases, infections, medications, and autoimmune disorders. Here, we present a case of LCV in a patient with decompensated heart failure. A 58-year-old man presented with progressively deteriorating swelling in both his lower limbs and scrotum, a persistent dry cough associated with minor ulcerative lesions on his shins, and a patchy rash with pustules and flat reddish spots. He was hospitalized three days prior due to atrial fibrillation and rapid ventricular rate, for which he was commenced on amiodarone. This rash persisted for three days, yet he denied experiencing any discomfort or itchiness along with it. Based on his clinical picture, laboratory evaluations, and imaging findings, he was diagnosed with LCV induced by amiodarone.

Trifoliate gallbladder: A rare congenital anomaly masquerading as acute cholecystitis.

Key Clinical Message: Triple gallbladder, an extremely rare congenital anomaly, can mimic more common biliary conditions. Accurate diagnosis through imaging and a multidisciplinary approach is essential for timely surgical management, preventing complications, and ensuring better patient outcomes. Abstract: The multiplication of the gallbladder is a congenital malformation with a rare incidence of 1 in 4000 patients, among which the trifoliate gallbladder, even rarer, is included. Gallbladder anomalies are typically discovered incidentally while investigating conditions like gallstones, sedimentation, gallbladder inflammation, or malignancy. The clinical presentation of trifoliate gallbladder disease varies, and it may require a variety of imaging modalities to obtain a preoperative diagnosis. Recommended therapeutics for this anomaly are open or laparoscopic cholecystectomy, depending on the patient's condition. Early diagnosis of gallbladder multiplications is vital to improve prognosis and mitigate the risk of complications like cholelithiasis, cholecystitis, metaplasia, and adenocarcinoma. In our case, we present a 30-year-old male with the diagnosis of acute cholecystitis with triple gallbladder. A confirmatory diagnosis was made with magnetic resonance cholangiopancreatography (MRCP). The patient responded well to the therapy given and was discharged for follow-up.

Analysis of Risk Factors for Cholelithiasis: A Single-Center Retrospective Study.

Objectives Cholelithiasis poses a considerable medical burden worldwide. While its pathogenesis is multifactorial, identifying the key risk factors is essential for understanding the disease and improving patient care. This study aims to investigate the potential associations between demographic, clinical, and laboratory variables and the development of cholelithiasis. Methods This single-center retrospective study was conducted at Malla Reddy Institute of Medical Sciences, Hyderabad, India, over one month. A total of 200 patients diagnosed with cholelithiasis were included. Data were extracted from electronic health records and the patients using a questionnaire, including demographic information (age, gender), clinical data including body mass index (BMI), and comorbidities. Statistical analyses were conducted to determine the associations between risk factors and cholelithiasis. Results The frequency of cholelithiasis is found to be higher in the female gender and patients with obesity, sedentary lifestyle and hypertension as compared to male patients, and the risk of cholelithiasis also increases with age. Females demonstrated a higher prevalence of cholelithiasis, with an odds ratio (OR) and confidence interval (CI) of 1.4, 95% CI [1.1, 1.7], p < 0.05). Obese individuals (BMI ≥ 30) had 2.2 times higher odds of cholelithiasis compared to those with normal BMI (< 24.9) (OR = 2.2, 95% CI [1.7, 2.9], p < 0.001). The presence of diabetes significantly increased the odds of cholelithiasis by 1.6 times (OR = 1.6, 95% CI [1.2, 2.1], p < 0.01). Overweight individuals (BMI: 25-29.9) were associated with 1.4 times higher odds of cholelithiasis (OR = 1.4, 95% CI [1.1, 1.9], p < 0.05). Conclusion Our study identified age, gender, BMI, diabetes, and obesity as significant risk factors for cholelithiasis. These findings underscore the importance of targeted interventions and lifestyle modifications to mitigate cholelithiasis risk and improve patient outcomes. Further research, including prospective multicentric studies, must validate these findings and explore potential underlying mechanisms.

Acute Appendicitis with Appendicolith and its Complication and Management: A Case Report.

Acute appendicitis is a common cause of acute abdominal pain requiring urgent surgery. Despite characteristic clinical signs, diagnosis can be challenging, leading to unnecessary appendectomies. This case report focuses on a 34-year-old male with escalating right lower quadrant abdominal pain. Imaging revealed acute appendicitis with a substantial appendicolith. Surgical intervention involved a open appendectomy with possible ileocecal resection due to cecal inflamation. Surgical findings indicated successful resection, and the patient recovered without complications. While urgent appendectomy is the norm, conservative approaches are gaining traction for peri-appendiceal abscesses. Interval appendectomy post-conservative treatment is a debated strategy. Management decisions are influenced by patient factors and disease severity. Future research is needed to establish standardized treatment protocols for complicated appendicitis. The case illustrates the evolving landscape of acute appendicitis management.

A Rare Case of Small Bowel Intussusception in an Elderly: A Case Report and Literature Review.

Intussusception, a rare cause of bowel obstruction in adults, is even less common in the elderly population. Unlike pediatric cases, adult intussusception is primarily associated with pathologic diseases acting as lead points, often requiring surgical intervention. We present a case of an 84-year-old male with a medical history significant for multiple comorbidities, who was diagnosed with a large segment jejunojejunal intussusception resulting in small bowel obstruction. Surgical management was recommended, and an exploratory laparotomy with bowel resection was performed, including the excision of the leading point. This case highlights the challenges in diagnosing adult intussusception and the importance of surgical intervention due to the high incidence of associated pathologic diseases.

Comparison of Out-of-Hospital Cardiac Arrest Outcomes Between Asian and White Individuals in the United States.

Background Disparities in bystander cardiopulmonary resuscitation (CPR) and survival have been reported for Black and Hispanic individuals with out-of-hospital cardiac arrest (OHCA). Whether Asian individuals have lower rates of bystander CPR and survival for OHCA, as compared with White individuals, remains unknown. Methods and Results Within the US-based CARES (Cardiac Arrest Registry to Enhance Survival), we identified 278 989 OHCAs in Asian and White individuals during 2013 to 2021. Using hierarchical Poisson logistic regression with emergency medical service agency modeled as a random effect and patient and OHCA characteristics as fixed effects, we compared rates of bystander CPR, survival to discharge, and favorable neurological survival between Asian and White individuals with OHCA. Overall, 14 835 (5.3%) OHCAs occurred in Asian individuals. Compared with White individuals with OHCA, Asian individuals were older (67.0±17.6 versus 62.8±16.9 years) and were less likely to have drug overdose as the cause of OHCA (1.3% versus 6.6%) and a shockable arrest rhythm (19.2% versus 22.4%). Layperson bystander CPR rates were similar between Asian and White individuals (42.6% versus 42.1%; adjusted relative risk for Asian individuals, 0.99 [95% CI, 0.97-1.02]; P=0.69). However, rates of survival to discharge were lower in Asian individuals with OHCA (8.2% versus 10.3%; adjusted relative risk 0.92 [0.86-0.98] P=0.006). Similarly, the rate of favorable neurological survival was lower for Asian individuals (6.5% versus 8.7%; adjusted relative risk, 0.85 [0.79-0.91]; P<0.001). Conclusions Despite similar rates of bystander CPR, Asian individuals with OHCA have lower survival rates than White individuals with OHCA. The reasons for the lower survival rate deserve further study to determine whether there are disparities in resuscitation care between Asian and White individuals with OHCA.

Odor identification errors reveal cognitive aspects of age-associated smell loss.

Human olfaction can be extraordinarily sensitive, and its most common assessment method is odor identification (OID), where everyday odors are matched to word labels in a multiple-choice format. However, many older persons are unable to identify familiar odors, a deficit that is associated with the risk of future dementia and mortality. The underlying processes subserving OID in older adults are poorly understood. Here, we analyzed error patterns in OID to test whether errors could be explained by perceptual and/or semantic similarities among the response alternatives. We investigated the OID response patterns in a large, population-based sample of older adults in Sweden (n = 2479; age 60-100 years). Olfaction was assessed by a 'Sniffin ́ TOM OID test with 16 odors; each trial involved matching a target odor to a correct label among three distractors. We analyzed the pattern of misidentifications, and the results showed that some distractors were more frequently selected than others, suggesting cognitive or perceptual factors may be present. Relatedly, we conducted a large online survey of older adults (n = 959, age 60-90 years) who were asked to imagine and rate the perceptual similarity of the target odors and the three corresponding distractors (e.g. "How similar are these smells: apple and mint?"). We then used data from the Swedish web corpus and the Word2Vec neural network algorithm to quantify the semantic association strength between the labels of each target odor and its three distractors. These data sources were used to predict odor identification errors. We found that the error patterns were partly explained by both the semantic similarity between target-distractor pairs, and the imagined perceptual similarity of the target-distractor pair. Both factors had, however, a diminished prediction in older ages, as responses became gradually less systematic. In sum, our results suggest that OID tests not only reflect olfactory perception, but also likely involve the mental processing of odor-semantic associations. This may be the reason why these tests are useful in predicting dementia onset. Our insights into olfactory-language interactions could be harnessed to develop new olfactory tests that are tailored for specific clinical purposes.

Frailty in Aging HIV-Positive Individuals: An Evolving Healthcare Landscape.

The life expectancy of people living with HIV (PLWH) has greatly increased due to advancements in combination antiretroviral treatment (cART). However, this longer life has also increased the prevalence of age-related comorbidities, such as frailty, which now manifest sooner in this group. Frailty, a term coined by the insurance industry, has been broadened to include physical, cognitive, and emotional elements and has been recognized as a critical predictor of negative health outcomes. With the median age of PLWH now in the mid-50s, treating frailty is critical given its link to chronic diseases, cognitive decline, and even death. Frailty assessment tools, such as the Frailty Phenotype (FP) and the Frailty Index (FI), are used to identify vulnerable people. Understanding the pathophysiology of frailty in PLWH indicates the role of immunological mechanisms. Frailty screening and management in this group have progressed, with specialized clinics and programs concentrating on multidisciplinary care. Potential pharmacotherapeutic solutions, as well as novel e-health programs and sensors, are in the future of frailty treatment, but it is critical to ensure that frailty evaluation is not exploited to perpetuate ageist healthcare practices. This narrative review investigates the changing healthcare environment for older people living with HIV (OPLWH), notably in high-income countries. It emphasizes the significance of identifying and managing frailty as a crucial feature of OPLWH's holistic care and well-being.

Perceptual odor qualities predict successful odor identification in old age.

Odor identification is a common assessment of olfaction, and it is affected in a large number of diseases. Identification abilities decline with age, but little is known about whether there are perceptual odor features that can be used to predict identification. Here, we analyzed data from a large, population-based sample of 2,479 adults, aged 60 years or above, from the Swedish National study on Aging and Care in Kungsholmen. Participants performed both free and cued odor identification tests. In a separate experiment, we assessed perceived pleasantness, familiarity, intensity, and edibility of all odors in the first sample, and examined how odor identification performance is associated with these variables. The analysis showed that high-intensity odors are easier to identify than low-intensity odors overall, but also that they are more susceptible to the negative repercussions of old age. This result indicates that sensory decline is a major aspect of age-dependent odor identification impairment, and suggests a framework where identification likelihood is proportional to the perceived intensity of the odor. Additional analyses further showed that high-performing individuals can discriminate target odors from distractors along the pleasantness and edibility dimensions and that unpleasant and inedible odors show smaller age-related differences in identification. Altogether, these results may guide further development and optimization of brief and efficient odor identification tests as well as influence the design of odorous products targeted toward older consumers.

Multiple Sclerosis-Minimizing Errors in Radiological Diagnosis.

BACKGROUND: Multiple sclerosis is a chronic demyelinating disorder with a myriad of imaging and clinical features that overlap with number of other neurological conditions. Incorrect diagnosis poses a significant risk to patients, it may lead to delays in management, increased morbidity, and also adds to the financial cost. OBJECTIVE: The aim of this study was to highlight strategies for the efficient differentiation of multiple sclerosis from other diseases which may masquerade as MS clinico-radiologically. MATERIAL AND METHODS: A systematic literature review was conducted through online databases including PubMed and Medline. Relevant publications on radiological aspects of multiple sclerosis, white matter diseases and mimickers of Multiple sclerosis were included in the analysis. RESULTS: Common mimickers of MS include small vessel disease, acute disseminated encephalomyelitis, neuromyelitis optica, anti-MOG encephalomyelitis, vasculitis, and CADASIL. Contrast-enhanced MRI study performed using MS protocol on high strength MRI system evaluated following a structured protocol along with clinical correlation is effective in differentiating MS from its mimickers. CONCLUSIONS: Contrast-enhanced MRI performed on a high strength scanner using MS protocol with structured protocol for evaluation along, with a better collaboration between radiologists and clinicians may help in minimizing errors in diagnosis of multiple sclerosis.
