th any of the clinicopathological parameters, except for the lack of BCL-2 expression. Alternatively, from a pathological perspective, it is important to recognize this variant of DLBCL as it often mimics other CD30-positive lymphoma and undifferentiated carcinoma.Background and objective In low- and low-to-middle-income countries (LMICs), the incidence of treatment-related mortality (TRM) in patients with acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) is up to 52%. This study aimed to determine the mortality rate at the end of the induction phase of the treatment among patients with ALL and lymphoma at a tertiary care cancer center. Nanvuranlat Methods This retrospective study analyzed outcomes after induction chemotherapy in pediatric patients with acute leukemia and lymphoma at a tertiary care cancer center from January 2015 to December 2016. Information regarding demographics, clinical characteristics, and laboratory investigations were extracted and reviewed. Results Of the total 160 patients, 110 were males, and the mean age of the sample was 4.6 +2.8 years. B-cell leukemia (pre-B-ALL) was diagnosed in 84% (n=134), while 10% (n=6) had acute T-cell leukemia (pre-T-ALL) and 6% (n=10) had lymphoma. Sixteen patients (10%) died within the defined induction period, with 14 deaths occurring due to infections and two deaths resulting from chemotherapy-related toxicity. Conclusion Based on our findings, there is a significant prospect of mortality from infections during induction chemotherapy in patients with pediatric hematological malignancies.Since the coronavirus (COVID-19) pandemic started, new challenges have emerged regarding the management of coronavirus-infected patients. One of the most known devastating complications associated with COVID-19 is hypercoagulability. This can lead to severe disability or even death, especially in critically ill patients with known chronic comorbidities such as hypertension (HTN) and diabetes. D-dimer and clinical condition are among the most important tools currently used by clinicians to guide therapy and anticoagulation prophylaxis. Here we present a case of a COVID-19-infected patient with no known comorbidities and mild elevation in initial D-dimer level who had a rapid deterioration ultimately leading to death within weeks of admission.Marijuana is the most commonly used illicit recreational drug in the United States. Growing public support for marijuana law reform has resulted in a significant increase in its use. The harmful pulmonary consequences of chronic marijuana smoking are less researched and discussed than those of tobacco smoking. We present a case of recurrent spontaneous pneumothorax in a patient with heavy, persistent marijuana abuse who has no past medical or surgical histories and denied smoking cigarettes or other illicit substance use.Achalasia is a relatively rare motor disorder characterized by esophageal aperistalsis and incomplete relaxation of the lower esophageal sphincter. In only 10% of patients, untreated or poorly managed achalasia can progress to esophageal dilation and eventual loss of total functionality resulting in a characteristic sigmoid dolichomegaesopahagus. In extremely rare instances, this sigmoid dolichomegaesopahagus can present clinically as acute airway obstruction or a fatal, life-threatening hemorrhage requiring immediate intervention. We present the case of a 65-year-old female with a past medical history of long-standing achalasia who had complaints of shortness of breath, chest pain, and two episodes of life-threatening hematemesis requiring a blood transfusion. An angiography illustrated significant distention of the esophagus occupying most of the right hemithorax and non-specific intraluminal fluid with a small amount of gas. Emergent esophagogastroduodenoscopy showed fibrosis and necrosis of the esophageal mucosa with food debris, suggesting that the bleeding was likely coming from an ulcer caused by pressure necrosis. The patient was hemodynamically unstable after the procedure and was transferred to another facility the next day for an esophagectomy. Patients with achalasia have an increased susceptibility to develop pressure ulcers due to increased shear force on the esophageal wall, increased moisture of the esophageal wall from prolonged contact of food boluses, and underlying malnutrition and weight loss from the indigestion of food causing atrophy of the mucosal barriers. The management of these ulcers is to treat and manage the underlying cause. Although there are no curative treatments for achalasia, symptomatic relief through both surgical and medical therapies are the mainstay of management, with an esophagectomy reserved for refractory cases or in patients who develop end-stage complications.The incidence of symptomatic vasculitis in human immunodeficiency virus (HIV)-infected patients is approximately 1%, and it commonly presents as arterial occlusive disease or aneurysmal disease. Early diagnosis of vascular complications in those patients is essential; however, it is extremely challenging. Iliac aneurysms are usually silent, and because of their deep location, detection of these aneurysms is typically difficult. Therefore, they always continue to be asymptomatic until rupture unless they are discovered incidentally on a radiological investigation for an irrelative condition. We present the case of a 61-year-old HIV-positive man with bilateral iliac aneurysms and total coronary artery occlusion presenting with a leg ulcer.A 54-year-old male with a history of hypertension, diabetes, and sleep apnea presented with a two-week history of dyspnea. The patient was hypoxic with bilateral leg edema. Initial workup showed elevated troponin at 0.15 ng/mL, brain natriuretic peptide of 720 pg/mL, and hyponatremia. Chest X-ray revealed lungs infiltrates with possible pneumonia. An electrocardiogram showed sinus tachycardia and ST depression in septal leads. He received diuretics and antibiotics for fluid overload and pneumonia. Blood culture showed methicillin-sensitive staphylococcus aureus (MSSA). Transthoracic echocardiogram (TTE) revealed a left ventricle ejection fraction (LVEF) of 55-60%, a bicuspid aortic valve (BAV) with mild aortic stenosis and calcification, and an ascending aortic aneurysm of 4.2 cm, though no vegetations. A transesophageal echocardiogram (TEE) demonstrated the BAV, 1.4 cm mobile vegetation, an abscess on the aortic annulus, severe aortic regurgitation, and 4.6 cm ascending aortic aneurysm. He underwent aortic valve replacement, ascending aortoplasty, and coronary artery bypass grafting. He was discharged with eight weeks of antibiotics after a good recovery with resolution of fever, dyspnea, and bacteremia. His son was diagnosed with BAV earlier. Consequently, by screening echocardiogram and education, our patient could have avoided complications of severe infective endocarditis.The treatment effects of metastasis-directed therapy in patients with oligometastatic disease have received much attention. In our case, a 72-year-old man with oligometastatic castration-resistant prostate cancer was referred to our hospital. The patient had undergone radical radiotherapy with a total dose of 76 Gy in 36 fractions for localized prostate cancer nine years prior to the first visit. Positron emission tomography showed a slight increase in accumulation in the para-aortic lymph nodes. The patient received conventional radiotherapy at a total dose of 50 Gy in 25 fractions to the para-aortic region as oligometastasis-directed local therapy. After radiotherapy, his prostate-specific antigen (PSA) level decreased slightly, but it increased again soon after. According to the results of positron emission tomography, the accumulation around the para-aortic lymph nodes had decreased; however, a slight increase in accumulation in the sub/supra-clavicular lymph nodes was observed. He received radiotherapy at a total dose of 50 Gy in 25 fractions to the sub/supra-clavicular region. We confirmed a significant reduction in lesion volume and a downward trend in PSA levels. Metastasis-directed therapy has shown remarkable effectiveness in controlling disease without severe treatment-related adverse events. Metastasis-directed therapy is considered as one of the treatment options in patients who need salvage therapy.Pseudotumor cerebri, or idiopathic intracranial hypertension (IIH), is a syndrome of elevated intracranial pressure (ICP) of unknown etiology that occurs predominantly in obese women of childbearing age. Pseudotumor cerebri literally means "false brain tumor". It is a "diagnosis of exclusion" therefore a complete work-up to rule out life-threatening causes for increased ICP must be performed through a comprehensive history, complete physical examination, diagnostic imaging, and cerebrospinal fluid (CSF) analysis before the diagnosis can be made. The authors present the case of a young woman with headache, and near blindness due to pseudotumor cerebri. link2 The presentation, diagnosis, and treatment options are discussed.Severe acute respiratory syndrome coronavirus 2, responsible for coronavirus disease 2019 (COVID-19), is a pandemic that has taken the world by storm. We present the only contemporary reported case of COVID-19 myocarditis leading to recovery with utilization of biventricular Impella (Abiomed, Danvers, MA, USA) for temporary mechanical circulatory support. A 35-year-old female with systemic sclerosis who was found to have five days of generalized malaise associated with fevers and cough. She tested positive for COVID-19 via nasal polymerase chain reaction. link3 Cardiac enzymes were found elevated on admission. Invasive hemodynamics assessment was significant for elevated right and left-sided filling pressures, along with calculated cardiac index of 1.3 L/min/m2. Decision was made to place right and left-sided ventricular support with percutaneous Impella for mechanical circulatory support. She was started on intravenous immunoglobulin for suspected COVID-19 myocarditis along with remdesivir and solumedrol. After two weeks of continuous temporary mechanical circulatory support, the patient's hemodynamics improved and she was discharged. Repeat echocardiogram demonstrated normalization of left ventricular function.Post-influenza myositis is considered a distinct clinical entity and is associated with muscle pain and elevated muscle enzymes during convalescence. Although the exact mechanism of muscle injury in acute viral myositis is unknown, there are possible mechanisms proposed in the literature. The progression of viral myositis to rhabdomyolysis, although uncommon, can be life-threatening and has been reported with many viruses, most commonly influenza. At our institution, a case of severe influenza-induced myositis prompted us to conduct a literature search focusing on the incidence, pathophysiology, typical presentation, and proper diagnosis of this rare condition.Saturday night palsy refers to neuropraxia of the radial nerve following prolonged compression against the spiral groove of the humerus. The pattern of weakness is unique with wrist, thumb, and finger drop, and recovery is universal by six months. What makes this clinical entity fascinating are the toxic and metabolic diseases that can manifest similarly, namely, plumbism (Saturnism) and acute porphyrias. The acute porphyrias (heme biosynthetic inborn errors of metabolism) are well known to cause motor neuropathy, with upper more than lower limb weakness, with wrist, thumb and finger drop a frequent manifestation. Intriguingly, lead neurotoxicity (plumbism), which has historically been tightly associated with wrist, thumb, and finger drop, is associated with the inhibition of at least three enzymes of heme biosynthesis. Mechanistically, interference with heme ring synthesis interferes with electron transport chain protein synthesis, which leads to oxidative phosphorylation defects, energy failure, axonal transport impairment, and, subsequently, an axonopathy.
