Idiopathic Pulmonary Fibrosis Comorbid With Mediastinal Small Cell Carcinoma: A Clinical Dilemma.

We present an interesting case of mediastinal small cell carcinoma (MSCC), an exceedingly rare entity, comorbid with idiopathic pulmonary fibrosis (IPF). A 66-year-old female was first seen in the pulmonology office for abnormal chest computed tomography (CT) findings of right apical bronchiectasis and subpleural fibrotic changes with focal pleural thickening along the fissures, along with a right lower lobe nodule. Pulmonary function testing (PFT) showed an obstructive pattern with modest bronchodilator response, although subsequent PFT showed a worsening restrictive pattern with a worsening DLCO. On a follow-up CT one year later, a soft tissue density with peripheral calcification was found in the anterior mediastinum, later found to be hypermetabolic on a PET scan. Radiographically, fibrosis worsened with the appearance of worsening diffuse bilateral coarse reticular interstitial changes with lower lobe predominance, honeycombing, and areas of ground-glass opacity. A biopsy of the mediastinal lesion showed a high-grade neuroendocrine tumor. Cam5.2, insulinoma-associated protein-1, synaptophysin, and thyroid transcription factor-1 immunostains were positive. She underwent four cycles of chemotherapy with cisplatin and etoposide with a total of 60 Gy of radiation. Mediastinal mass started to decrease in size. Her respiratory status, imaging, and PFTs continued to show evidence of IPF progression. Prednisone resulted in modest clinical and radiographic response. Steroid-sparing therapy with mycophenolate mofetil, although effective, had to be discontinued due to GI bleeding. Anti-fibrotic therapy was deferred due to evidence showing a lack of clinical improvement. We discuss the existing evidence available on IPF management and proceed to highlight the deficiencies in existing data available on the management of IPF and MSCC in these patients. Most of the cases of MSCC reported in the past have managed MSCC using guidance from treatment practices for small cell lung cancer. No reported cases discuss or describe the management of IPF and MSCC in the very rare cohort of patients our case represents.

Sweet Syndrome With Vasculitis: Time To Adopt a New Criteria?

Sweet syndrome (SS) is an acute febrile neutrophilic dermatosis. Although perceived to be rare, the disease may well have been underreported due to lack of exposure in low-volume clinical settings and due to the use of rather strict clinical criteria for diagnosis. It presents as cutaneous papules, plaques, or nodules in an asymmetric distribution that follows fever and flu-like symptoms. Data on the disease is ever-expanding. Several associations have been identified, including drugs, infections, malignancies, and autoimmune diseases. Different disease patterns and histological variants have been identified. Pathophysiology is complex and multifactorial but appears to involve mechanisms that negatively influence neutrophil apoptosis and facilitate neutrophil recruitment. The existing diagnostic criteria exclude cases with vasculitis; over time, cases of neutrophilic dermatoses with vasculitis have been reported as SS as long as other criteria were met. Newer diagnostic models have been proposed, some arguing against the exclusion of vasculitis. Steroids continue to be the mainstay of treatment, and steroid responsiveness continues to be a part of the diagnostic criteria, although newer treatment modalities have been used and have shown promise. No established guidelines exist for management. We present a case of Idiopathic SS with vasculitis along with a brief review of the existing literature. We agree to the inclusion of vasculitis as proposed by the newer diagnostic criteria.

A Case of Dulaglutide-Induced Vaginal Bleed.

Type 2 diabetes mellitus (T2DM) is a growing challenge across the globe. The disease process is amendable to lifestyle modifications in the early stages. If those changes fail to correct endocrine dysfunction, medical therapy is initiated. Initially, therapy for type 2 diabetes consisted of biguanides and sulfonylureas. With modern medicine, we have developed dipeptidyl peptidase-4 inhibitors, sodium-glucose cotransporter-2 inhibitors, and glucagon-like peptide 1 (GLP-1) receptor agonists. Dulaglutide is a GLP-1 receptor agonist that is sold under the brand name Trulicity. The most common side effect associated with Dulaglutide is gastrointestinal discomfort. We present a case of severe vaginal bleeding due to a rare side effect of Dulaglutide. A 44-year-old perimenopausal female with a past medical history of type 2 diabetes mellitus presented to the clinic after experiencing significant vaginal bleeding. The patient was unable to tolerate Metformin and Semaglutide in the past. The abnormal vaginal hemorrhage started one week after receiving the second dose of Dulaglutide. Her hemoglobin concentration fell significantly. Dulaglutide was immediately discontinued, and her vaginal bleeding stopped. This case documents the necessity of post-market surveillance to oversee the safety of recently approved medications by the Food and Drug Administration (FDA). Rare side effects can emerge in the general population that were not seen during clinical trials. Physicians should consider the possibility of adverse medication reactions when determining whether to start a new medication or a conventional one.

A Case Report of Brucellosis-Associated Infective Endocarditis.

Brucellosis is a prevalent zoonotic infection that can be relatively well managed and tolerated if appropriate treatment is initiated. Unfortunately, likely secondary to decreased awareness and vague symptoms, the diagnosis can be easily missed leading to worsening complications that severely increase the mortality rate. We present a case of a 25-year-old female who presented from a rural setting with a diagnosis of brucellosis, which was delayed. She ultimately developed infective endocarditis with cardiac vegetations on imaging. Despite improvement on antibiotics and reduction in size of cardiac vegetation, she suffered a fatal cardiac arrest before undergoing surgical intervention. Better awareness regarding hygiene and sanitary food handling should be encouraged, especially in underdeveloped rural areas, to help prevent infection. More studies need to be performed to help better identify symptoms coupled with maintaining a high index of suspicion so as to expedite diagnosis, treatment, management and hopefully prevent the progression of disease and worsening complications.

To Bleed or Not to Bleed.

The location of gastrointestinal (GI) bleeding can be characterized based on the characteristics of the bowel movements these patients present with. Bright red blood per rectum is usually associated with a lower bleed; if brisk and significant enough, however, upper bleeds can present similarly. Melenic or "tar-colored" bowel movements are more likely to occur from upper bleeds as the color is secondary to digestion of hemoglobin as it passes through the GI tract. At times, there can be a mix of the two which can make a clinical decision for intervention less obvious. To make matters more difficult, some of these patients can be on anticoagulation therapy for a myriad of reasons. Risks versus benefits at these times need to be weighed as holding this therapy may make the patients more prone to clotting while continuation would increase likelihood of bleeding. We present a case of a hypercoagulable patient who was started on rivaroxaban for history of pulmonary embolism; this led to the onset of an acute GI bleed from a duodenal diverticulum requiring endoscopic intervention. Although this can be a known effect of the therapy, the severity of bleed and changes in hemodynamics can warrant very different management strategies.

A Rare Manifestation of Hepatitis A Associated Cryoglobulinemia.

Cryoglobulins can precipitate in the blood when exposed to lower temperatures. These abnormal immunoglobulins are more commonly affiliated with Hepatitis C infection but there have been cases reported with Hepatitis A association for which we present this case. The patient was treated with steroids which did show gradual improvement of symptoms but, ultimately, the patient developed renal failure and required temporary hemodialysis. Care should be taken to assess patients with cryoglobulins for other viral serologies besides Hepatitis C.

A Rare Case of Paxlovid-Induced Pancreatitis.

Acute pancreatitis can result secondary to an inflammatory cascade due to an insult to the pancreatic parenchyma, whether it be from infections, medications, etc. We present a case of a 37-year-old male with acute pancreatitis after being started on Paxlovid, a combination drug containing Nirmatrelvir and Ritonavir, for COVID-19 treatment. Multiple reports in the literature have documented such an association between acute pancreatitis and the protease inhibitor Ritonavir. We suspect that similar results may have taken place that link the initiation of this medication with pancreatic inflammation.

Brain Abscess as a Complication of Hereditary Hemorrhagic Telangiectasia: A Case Report.

An 18-year-old male, previously diagnosed with hereditary hemorrhagic telangiectasia (HHT), presented to the outpatient department with a complaint of generalized seizures and fever for the past five days. He had a history of recurrent epistaxis, progressive shortness of breath, and cyanosis. Magnetic resonance imaging (MRI) of the brain revealed an abscess in the temporoparietal region. A computed angiogram of the pulmonary vasculature showed the presence of arteriovenous malformation (AVM). A four-weekly antibiotic regimen was initiated, which resulted in a profound improvement in symptoms. A brain abscess can arise as a complication of vascular malformation in a patient with HHT, providing a nidus for bacteria to migrate toward the brain. Early recognition of HHT is essential in these patients and their affected family members, as screening can help us prevent complications at an earlier stage.

Moebius Syndrome: What We Know So Far.

Moebius syndrome (MBS) is a rare congenital cranial nerve disorder characterized by unilateral, bilateral symmetrical, or asymmetrical facial (VII) and abducens (VI) nerve palsies. Genetics and rhombencephalon vascular disturbances from intrauterine environmental exposures have been attributed to its development. It can present with various orofacial abnormalities. Although the diagnosis is purely clinical, certain characteristic features are present in the brain's images. With no cure, it is essential to devise management on a personalized basis. We discuss etiology, presentation, diagnostic approaches, and effective management in the existing literature. This comprehensive review examines the clinic-pathological aspects of Moebius syndrome. The authors employed the PUBMED base index to identify pertinent literature and reference it according to research keywords. Findings suggest the most popular etiology is the theory of intrauterine vascular disruption to the brainstem during embryogenesis, followed by the genetic hypothesis. Intrauterine environmental exposures have been implicated as potential risk factors. Facial and abducens nerve palsies are the most common presenting features. However, clinical manifestations of lower cranial nerves (IX, X, XI, XII) may be present with orthopedic anomalies and intellectual deficiencies. The diagnosis is clinical with minimal defined diagnostic criteria. Characteristic radiological manifestations involving the brainstem and cerebellum can be observed in imaging studies. With no definitive treatment options, a multidisciplinary approach is employed to provide supportive care. Despite radiological manifestations, Moebius syndrome is diagnosed clinically. Although incurable, a multidisciplinary approach, with personalized rehabilitative measures, can manage physical and psychological deficits; however, standard guidelines need to be established.

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.

Rare Association of Budd-Chiari Syndrome With Celiac Disease: A Case Report.

Budd-Chiari associated with celiac disease is a rare phenomenon in the medical literature with annual incidence of less than five per million. The majority of the cases are reported from the North African region. Our patient presented in the out-patient department with symptoms of progressive abdominal distension, diffuse abdominal pain and shortness of breath for one year. She was a known case of celiac disease for the last three years. The clinical examination revealed ascites, jaundice, decreased air entry in basal segments bilaterally, and multiple hemangiomas all over the body. Haematological and biochemical investigations, including levels of pro-thrombotic factors and homocysteine level, turned out to be normal. However, computed tomography (CT) revealed hepatic vein obstruction. Hence, a diagnosis of Budd-Chiari syndrome was confirmed. The patient was managed with anticoagulants, diuretics and gluten-free diet. Within a month, the patient showed marked improvement with a significant reduction in ascites. To the best of our knowledge, this rare association is the first case to be reported from Pakistan and third from the region of South Asia.

Right Scapular Swelling Revealed to Be a Spontaneous Lateral Chest Wall Hematoma: An Intriguing Case Report.

Chest wall hematoma commonly occurs as a result of blunt thoracic trauma. We report an intriguing case of spontaneous lateral chest wall hematoma that presented with right scapular swelling and tenderness on palpation having hemodynamic instability without any prior history of recent trauma or surgery. Chest x-ray and ultrasound were carried out at the time of admission to evaluate the swelling, followed by contrast-enhanced CT (CECT) of the chest to identify and localize the bleeder. Transcatheter arterial embolization (TAE) of the intercostal artery was performed to treat the condition successfully. CECT is found to be vitally important in localizing bleeders. Other possible options include exploratory thoracotomy, video-assisted thoracic surgery (VATS) exploration, and angiography.

A Case Report of Metallosis With a Failed Distal Femur Plate.

Metallosis is a very rare condition that poses a diagnostic challenge. Its precise incidence is not known and the condition should be suspected in patients who present with the clinical signs and symptoms discussed below. In particular, physicians and surgeons should pay special attention to whether metal prosthesis has been used for fracture repair or joint function. Here we report the case of a 40-year-old male who presented at an orthopedic surgery outpatient department in a tertiary care hospital with pain in the right distal thigh that had been ongoing for three months and swelling that had been ongoing for two months. According to the patient, he had received an operation for a right-sided distal femur fracture that was fixed with plate at a different hospital one year prior. Despite receiving all the appropriate physical exams and labs, and getting a radiologic workup, the diagnosis was unclear, and ultimately surgical exploration was conducted, which led to the diagnosis of metallosis. Although metallosis is a well-known complication, due to its rarity, physicians and surgeons often forget to keep metallosis as a differential that leads to diagnostic difficulties.
