Successful Management of Atypical Hemolytic-Uremic Syndrome in Pregnancy Using Eculizumab: A Case Review.

Hemolytic-uremic syndrome (HUS) is a rare thrombotic microangiopathy characterized by the triad of microangiopathic hemolytic anemia (MAHA), thrombocytopenia, and acute kidney injury. The disease is pathologically marked by fibrinoid necrosis within renal arterioles and glomerular capillaries. HUS can be categorized into typical variants, often linked to Shiga toxin-producing Escherichia coli (STEC) infection, and atypical variants that stem from dysregulation in the alternative complement pathway. Pregnancy is a recognized predisposing condition for HUS due to the potential reduction in complement regulatory proteins and the possibility of heightened maternal immune response. This report illustrates the case of a 36-year-old woman who, at 36 weeks of gestation, faced a breech presentation and was diagnosed with atypical HUS (aHUS) after placental abruption. Following a cesarean section, she developed complications, including a pelvic hematoma and bilateral hydronephrosis. Despite initial suboptimal response to plasmapheresis, the patient exhibited marked clinical improvement with eculizumab treatment, with no evidence of disease relapse.

Glass in the Airways: A Bronchoscopic Challenge.

Foreign body aspiration (FBA) in adults is indeed a significant medical concern, albeit less common than in children. The increase in incidence with advancing age can be attributed to factors such as a decline in mental status and impairment of the swallowing reflex, which is more prevalent in the elderly population. The symptoms of FBA are highly variable, ranging from severe, acute asphyxiation, which may or may not involve complete airway obstruction, to more subtle signs like coughing, shortness of breath (dyspnea), choking, or fever. These varied presentations, coupled with the fact that many other medical conditions can mimic the respiratory symptoms seen in FBA, make diagnosis challenging. A high index of suspicion is often required, especially in cases where the patient's history does not clearly point toward aspiration. Immediate management focuses on supporting the airway, which is crucial given the potential for severe obstruction. Radiographic imaging plays a key role in localizing the foreign body, which is vital for planning its removal. Bronchoscopy, particularly flexible bronchoscopy, is the cornerstone of both diagnosis and treatment. This technique allows for direct visualization of the airways, localization of the foreign body, and its subsequent removal. This is crucial to avoid long-term complications, which can arise if the foreign body is not promptly and effectively removed. In this case report, we present a 64-year-old female patient who was found to have a foreign object positioned in the right lower lobe of the lungs that was removed via flexible bronchoscopy.

Advancements in MitraClip Intervention for Mitral Regurgitation: A Comprehensive Review and Comparative Analysis of Clinical Trials.

This comprehensive review explores the evolution and clinical impact of MitraClip intervention in the management of mitral regurgitation. Mitral regurgitation results from dysfunction in the mitral valve (MV) apparatus. The MitraClip Clip Delivery System was approved by the Food and Drug Administration (FDA) in 2013. The discussion delves into the procedural foundation of MitraClip intervention, primarily based on Alfieri's technique of edge-to-edge leaflet approximation. As highlighted by key clinical trials, including Endovascular Valve Edge-to-Edge Repair (EVEREST) II Trial, Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) Trial, and Percutaneous Repair with the MitraClip Device for Severe Functional/Secondary Mitral Regurgitation (MITRA-FR) trial, the efficacy and safety of MitraClip were evaluated in comparison to surgical interventions and guideline-directed medical therapy. Notably, the COAPT demonstrated significant benefits in reducing all-cause mortality and heart failure hospitalization, while the MITRA-FR presented contrasting results, emphasizing the importance of patient selection. An analysis of the EVEREST II trial underscores MitraClip's potential to achieve comparable outcomes to surgical intervention, emphasizing its role in reducing mitral regurgitation and improving clinical status. However, limitations and complications, such as device-related issues and the potential impact on future MV surgery, are discussed. The study also explores the evolving landscape of MV interventions, reflecting advancements and the growing acceptance of MitraClip. In conclusion, the MitraClip device represents a significant advancement in the treatment of mitral regurgitation. The data presented highlights its promising results in terms of reduced hospitalization rates, improved in-hospital mortality, and enhanced quality of life for patients. However, challenges remain, and careful consideration of patient selection and underlying pathology is crucial in determining the optimal treatment approach. Ongoing research and clinical experience will continue to refine our understanding of MitraClip's role in the evolving landscape of MV interventions.

Extended-Spectrum Beta-Lactamase Escherichia coli-Associated Acute Cholangitis: Uncommon Patient Characteristics and Clinical Implications.

Acute cholangitis is a potentially life-threatening condition caused by an infection of the biliary tract resulting from biliary obstruction. This case report highlights an unusual presentation of acute cholangitis in an elderly patient characterized by the presence of extended-spectrum beta-lactamase-producing Escherichia coli. We aim to emphasize the significance of recognizing diverse clinical manifestations in the elderly population to enhance timely diagnosis and appropriate management. The case highlights the importance of better understanding patient risk factors for potential causative organisms and their susceptibility to selecting proper antibiotics and improving clinical outcomes.

Metabolic Dysfunction-Associated Steatohepatitis and Progression to Hepatocellular Carcinoma: A Literature Review.

The prevalence of metabolic-associated fatty liver disease (MAFLD) is increasing globally due to factors such as urbanization, obesity, poor nutrition, sedentary lifestyles, healthcare accessibility, diagnostic advancements, and genetic influences. Research on MAFLD and HCC risk factors, pathogenesis, and biomarkers has been conducted through a narrative review of relevant studies, with a focus on PubMed and Web of Science databases and exclusion criteria based on article availability and language. Steatosis marks the early stage of MASH advancement, commonly associated with factors of metabolic syndrome such as obesity and type 2 diabetes. Various mechanisms, including heightened lipolysis, hepatic lipogenesis, and consumption of high-calorie diets, contribute to the accumulation of lipids in the liver. Insulin resistance is pivotal in the development of steatosis, as it leads to the release of free fatty acids from adipose tissue. Natural compounds hold promise in regulating lipid metabolism and inflammation to combat these conditions. Liver fibrosis serves as a significant predictor of MASH progression and HCC development, underscoring the need to target fibrosis in treatment approaches. Risk factors for MASH-associated HCC encompass advanced liver fibrosis, older age, male gender, metabolic syndrome, genetic predispositions, and dietary habits, emphasizing the requirement for efficient surveillance and diagnostic measures. Considering these factors, it is important for further studies to determine the biochemical impact of these risk factors in order to establish targeted therapies that can prevent the development of HCC or reduce progression of MASH, indirectly decreasing the risk of HCC.

Comprehensive Review of Mesothelioma Cases: From Diagnosis to Therapeutic Strategies.

Mesothelioma is a rare and aggressive malignancy typically associated with asbestos exposure. We present the clinical and diagnostic journey of a 63-year-old male carpenter, who presented with concerning symptoms of shortness of breath and total right lung "white-out" on imaging. Comprehensive medical evaluation revealed the presence of malignant pleural mesothelioma. This study underscores the importance of considering mesothelioma as a potential diagnosis in individuals with occupational asbestos exposure and highlights patterns in diagnosing and managing this devastating disease. Early recognition and intervention are essential in improving outcomes for patients diagnosed with mesothelioma.

Gastrointestinal Tract Challenges: Chronic Inflammatory Fibroid Polyps Demystified.

An inflammatory fibroid polyp (IFP), also known as Vanek's tumor, is an uncommon benign tumor typically found as a solitary, intraluminal polyp in the gastrointestinal (GI) tract. Chronic IFP is characterized by persistent or recurrent inflammatory features, distinct histopathological findings, and a potential for significant GI tract involvement. Typically, IFPs occur predominantly in the gastric antrum, small intestines, and recto-sigmoid colon. They initiate within the submucosal layer and extend into the lamina propria, resulting in a noticeable bulging of the mucosal layer. They may breach the mucosal barrier on rare occasions, leading to ulceration and bleeding. This ongoing bleeding can induce persistent blood loss and symptoms typical of hypovolemic shock. When of smaller size, these growths might be accidentally detected during an endoscopic examination. Conversely, if the lesions are sizable, they can prompt symptoms of obstruction like queasiness, retching, and abdominal discomfort. Here, we present a case of a 47-year-old female who underwent a screening colonoscopy and was found to have an IFP.

Necrotizing Autoimmune Myopathy: A Case Report on Statin-Induced Rhabdomyolysis.

Statin-induced necrotizing myopathy (SINM) is an uncommon but severe complication associated with statin medication. SINM can develop at any point after a person starts taking steroids. It is now being acknowledged as a component of the broader category of "statin-induced myopathy." Like other immune-mediated necrotizing muscle diseases, statin-induced myositis is identified by weakness in proximal muscles, increased serum creatine kinase (CK) levels, and, in some cases, dysphagia and respiratory distress. In addition, there is evidence of muscle cell damage when examined under a microscope, occurring with minimal or no infiltration of inflammatory cells. Diagnosing SINM promptly is frequently challenging due to its unpredictable development over time, with symptoms sometimes emerging many years after the initial exposure to statins. One distinctive characteristic of SINM is the continued presence of muscle inflammation and elevated CK levels even after discontinuing statin treatment. Currently, no clinical trials are available to guide how to manage statin-induced immune-mediated necrotizing myopathy (IMNM). Here, we present a case of a 42-year-old woman diagnosed with SINM and was found to have persistently elevated CPK despite discontinuation of statins. Our case also suggests that intravenous (IV) immunoglobins and steroids are an effective and well-tolerated alternative to immunosuppressants.

When Meals Turn Into a Medical Mystery: A Case Report of Sigmoid Colon Impaction by a Chicken Bone.

The presence of foreign objects in the digestive system can lead to various complications within the gastrointestinal (GI) tract. In certain cases, ingesting foreign objects can pose a significant dilemma for surgical teams, primarily because they can lead to blockages or punctures in the upper or lower sections of the GI tract. On occasion, foreign objects located in the lower regions of the digestive tract, such as the colon and rectum, might have entered via the anal pathway, thereby carrying the potential risk of causing perforations in the rectum or sigmoid colon. The other complications encompass the creation of abscesses, blockages in the bowel, fistula, and bleeding. Although these issues associated with foreign objects can arise in a healthy bowel, they can pose challenges in diagnosis when occurring in a bowel that is already affected by inflammation, constrictions, or malignancy. We present a unique case report of a 72-year-old female who presented to the emergency department with left lower quadrant pain associated with nausea and vomiting. Following a detailed clinical evaluation and radiographic imaging, a chicken bone was identified as the culprit, causing an unusual impaction in the sigmoid colon. The patient's medical history revealed no prior GI complications, making this case particularly noteworthy. Timely identification and precise diagnosis of complications arising from foreign bodies are essential to efficiently handle and prevent unfavorable consequences.

Understanding Esophageal Diverticular Bleeding: Causes, Symptoms, and Treatment.

Esophageal diverticulum refers to a sac or protrusion formed by the epithelial-lined tissue of the esophagus. It can exist as either a true diverticulum involving all layers of the esophagus or a false diverticulum. Most cases of esophageal diverticula are acquired conditions that primarily affect older individuals. Typically, patients with a known motility disorder experience dysphagia as a common symptom of esophageal diverticulum; other symptoms include recurrent pneumonia, hoarseness, and halitosis. Failure to diagnose this condition promptly or accurately can result in more severe complications, such as gastrointestinal bleeding, lung abscesses, aspiration pneumonia, and cancer development. In this report, we present the case of a 68-year-old female who arrived at the emergency department with symptoms of epigastric discomfort and hematemesis and was found to have diverticula in the middle portion of the esophagus.

Esophagitis Dissecans Superficialis: Unveiling the Enigmatic Entity of Esophageal Mucosal Sloughing.

Esophagitis dissecans superficialis (EDS), formerly referred to as sloughing esophagitis, is a degenerative condition affecting the squamous epithelium. EDS is known to be a benign condition that resolves on its own. The exact etiology of EDS remains unclear, although associations with medications like bisphosphonates or nonsteroidal anti-inflammatory drugs, skin conditions, heavy smoking, and physical trauma have been reported. The clinical manifestations exhibit a wide range, encompassing both incidental findings and symptomatic presentations related to the esophagus. Here we present an interesting case of a middle-aged female patient with dysphagia who underwent early esophagogastroduodenoscopy (EGD) for timely identification and treatment of EDS, emphasizing the significance of early detection and management.

IgG4 Autoimmune Disease Masquerading As Oroantral Fistula.

IgG4-related disease (IgG4-RD) is an immune-mediated disorder that involves multiple organs and is characterized by the infiltration of lymphoplasmacytic cells, including IgG4-positive plasma cells, along with storiform fibrosis and obliterative phlebitis in the inflamed organs. The primary sites affected by this condition include the pancreas, bile ducts, salivary glands, aorta, lungs, kidneys, meninges, lacrimal glands, mediastinal lymph nodes, and retroperitoneum. The pathogenesis is linked to a type 2 T-helper-cell cytokine profile and the involvement of regulatory T cells. However, the exact mechanism is still unknown. Patients with IgG4-related disease are frequently misdiagnosed as having malignancies due to the resemblance of the lesions to infections or other immune-mediated diseases and certain tumors, such as pancreatic cancer and pseudo-renal pelvis tumor. Prompt identification of IgG4-related disease is essential as a delayed diagnosis until advanced stages can result in severe organ damage and potentially fatal outcomes, despite the disease being highly responsive to treatment. This report presents a highly unusual case of IgG4-related disease (IgG4-RD) with an atypical presentation in a 38-year-old female patient. The patient sought medical attention in the emergency department due to nasal septal erosions and an oral-antral fistula. Nasal cultures were conducted and indicated the presence of Klebsiella ozaena. Subsequent investigations, including a nasal biopsy, confirmed the diagnosis of IgG4-related autoimmune disease.

Adult T-Cell Lymphoma (ATL) With Erythroderma in Indolent Human T-Lymphotropic Virus Type I (HTLV-1) Infection.

Adult T-cell lymphoma (ATL) is a hematological malignancy of CD4+ mature T-lymphocytes commonly associated with chronic human T-lymphotropic virus type I (HTLV-1) infection. Chronic HTLV-1 infection induces oncogenic mutations in CD4+ T-cells, leading to an acute malignant transformation of host cells. Atypically, ATL presents with dermatological and pulmonary symptoms consistent with a "smoldering" disease pattern. We present a case of a 78-year-old male patient with chronic generalized malaise, progressively worsening shortness of breath, and diffuse erythroderma, who was diagnosed with ATL secondary to chronic indolent HTLV-1 infection. We evaluate the multisystemic clinical signs associated with ATL, the comprehensive clinical investigations required to reach a conclusive diagnosis, and the options for long-term clinical management.

Dieulafoy's Lesion of the Duodenum: A Rare and Fatal Cause of Gastrointestinal Bleed.

Dieulafoy's lesion (DL) is an unusual cause of recurrent gastrointestinal bleeding that can be fatal. It can occur in various parts of the gastrointestinal (GI) tract, most commonly located in the stomach, especially at the level of lesser curvature; however, it can occur in other parts, including the colon, esophagus, and duodenum. A duodenal Dieulafoy lesion is characterized by the presence of a larger-caliber artery that protrudes through the GI mucosa and can lead to massive hemorrhage. The exact cause of DL is yet to be determined. Clinical presentation includes painless upper GI bleeding, including melena, hematochezia, and hematemesis, or rarely iron deficiency anemia (IDA); however, most of the patients are asymptomatic. Some patients also have non-gastrointestinal comorbidities such as hypertension, diabetes, and chronic kidney disease (CKD). The diagnosis is established by esophagogastroduodenoscopy (EGD), which includes the presence of micro pulsatile streaming from a mucosal defect, the appearance of a fresh, densely adherent clot with a narrow point of attachment to a minute mucosal defect, and the visualization of a protruding vessel with or without bleeding. Initial EGD can be non-diagnostic due to the relatively small size of the lesion. Other diagnostic modalities include endoscopic ultrasound and mesenteric angiography. The treatment of duodenal DL includes thermal electrocoagulation, local epinephrine injection, sclerotherapy, banding, and hemoclipping. We present here a case of a 71-year-old female who had a history of severe IDA requiring multiple blood transfusions and intravenous iron in the past and was found to have duodenal DL.

Unveiling the Truth: Diagnosing Bacterial Meningitis Through Repeat Lumbar Punctures.

Bacterial meningitis is a cause of global concern given its associated high rates of mortality and complications. Timely diagnosis and management are crucial in improving outcomes in patients. Lumbar puncture and radiological investigations form the crux of diagnosis. However, the clinical course becomes complicated if lumbar puncture results are unrevealing and equivocal for bacterial meningitis. We present a case of a 60-year-old female who was diagnosed with bacterial meningitis on repeated lumbar puncture. Clinical vigilance and a high degree of suspicion is needed to ensure that patients with bacterial meningitis are diagnosed and managed appropriately, especially in cases with inconclusive lumbar puncture or radiological investigations.

Toxic Shock Syndrome Secondary to Erythroderma: Unraveling the Underlying Triggers.

Toxic shock syndrome (TSS) is a rare and life-threatening condition characterized by the systemic manifestation of severe infection. It is caused by exotoxin-producing strains of Staphylococcus aureus and Streptococcus pyogenes. Erythroderma, often described as generalized exfoliative dermatitis, is a rare and severe dermatological condition involving more than 90% of the body surface, identified as an uncommon cause of TSS. Here, we describe a case of a 72-year-old male who presented with signs and symptoms of erythroderma presenting as extensive erythematous scaling and lichenified plaques on multiple body surfaces and later developed TSS.

Enigma of Bowel Angina: Unraveling Celiac Trunk Stenosis.

The celiac axis is commonly involved in conditions that cause the narrowing or blockage of a celiac artery atherosclerosis and other vascular disease. Celiac artery compression syndrome is defined as chronic abdominal pain occurring because of compression of the celiac artery commonly in middle-aged (40 to 60 years) females. Various etiologies include atherosclerosis of mesenteries vessels, pancreatitis, median arcuate ligament syndrome, and tumor invasion. It is an uncommon condition, and symptoms include post-prandial abdominal pain mostly in the epigastrium, weight loss, nausea, diarrhea, anorexia, and bloating. Patients are asymptomatic for a prolonged duration due to collateral blood supply to the bowel from the patent superior mesenteric and inferior mesenteric arteries. We present a case of a 67-year-old female who initially presented with signs and symptoms suggestive of small bowel obstruction, however, due to persistent abdominal pain, she underwent a CT scan suggestive of severe celiac trunk stenosis causing abdominal angina. The patient was managed conservatively and responded well with close follow-up.

A 35-Year-Old Female With a Lupus Flare Presenting as Cardiac Tamponade: A Case Report.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder that affects multiple organ systems, significantly impacting the cardiovascular system. One potential complication of acute SLE flare is the development of pericardial effusion which can lead to potentially life-threatening consequences if not promptly identified. In this report, we describe the case of a 35-year-old female with a known history of SLE who developed rapid-onset, large-volume pericardial effusion with tamponade during a lupus flare. She received emergency treatment involving pericardiocentesis and was administered high doses of glucocorticoid and immunosuppressive medication. As a result, the pericardial effusion gradually resolved, and the patient's symptoms improved. This case emphasizes the significance of immediately identifying and managing swiftly progressing pericardial effusion in SLE patients. This is crucial as it can lead to severe and potentially lethal complications.

A Rare Case of Kikuchi-Fujimoto Disease.

Kikuchi-Fujimoto disease (KFD) is an autoimmune condition that is more common in females and occurs in the third decade of life. The condition is usually benign and self-resolving and is characterized by fever, cervical lymphadenopathy, night sweats, myalgia, and rashes. The disease can be misdiagnosed as reactive follicular hyperplasia, tuberculous lymphadenitis, systemic lupus erythematosus, and malignant lymphoma. The diagnosis of KFD involves the excision of the affected lymph node. Although there is no specific treatment for the disease, usually symptomatic and supportive measures are effective; however, steroids and immunosuppressive therapies are considered in more severe cases. The disease lasts for around one to four months. The neurological complications include cerebellar ataxia, meningoencephalitis, and aseptic meningitis. Here, we describe the case of a 36-year-old male who presented with complaints of fever, malaise chills, anorexia, and fatigue associated with a tender right axillary lymph node. The patient underwent a biopsy which confirmed KFD and responded well to supportive therapy.

Emphysematous Gastritis: A Case Series on a Rare but Critical Gastrointestinal Condition.

Emphysematous gastritis (EG) is a rare and life-threatening condition characterized by gas-forming microorganisms causing gas to accumulate within the stomach wall. It has a high mortality rate and is associated with risk factors like gastroenteritis, alcohol use disorder, diabetes mellitus, renal failure, recent abdominal surgery, long-term corticosteroid use, and ingestion of corrosive agents. Diagnosis is challenging due to its rarity and nonspecific symptoms, including severe abdominal pain, coffee-ground emesis, fever, and signs of systemic infection. We present two cases of patients with signs and symptoms of EG, where prompt diagnosis and treatment were achieved, avoiding further complications. Surgical intervention was avoided due to the successful response to conservative treatment. These cases highlight the importance of early detection and intervention in improving patient outcomes and preventing complications associated with EG.
