Septic Pylephlebitis in the Setting of COVID-19 Infection: A Case Report.

Portal vein thrombophlebitis is a rare complication that can occur in various hypercoagulable states, including COVID-19. We are presenting a 74-year-old female with a history of hypertension, diabetes, and lymphoma who contracted the COVID-19 infection and presented with persistent fever, leukocytosis, and mild epigastric tenderness. She developed hypotension, acute hypoxic respiratory failure, and worsening leukocytosis with bandemia and was diagnosed with portal vein thrombosis (PVT) and superior mesenteric vein thrombosis. The patient received broad-spectrum IV antibiotics and full anticoagulation therapy with heparin and was discharged on oral Warfarin after completing 14-day antibiotic therapy. She presented again with recurrent watery diarrhea, fever, abdominal pain, and fatigue and was diagnosed with pylephlebitis and multiple small liver abscesses. The patient was treated with antibiotics for six weeks and was discharged on warfarin, furosemide, and spironolactone with close outpatient follow-up. Prolonged fever in COVID-19 patients can indicate extensive thrombosis at unusual sites, which can lead to major morbidity and mortality in patients.

Pericardial Tamponade and Berger's Disease: An Unusual Association.

Cardiac tamponade is considered a medical emergency because a patient can deteriorate easily and die of cardiac arrest if the fluid is not drained immediately. The most common etiologies are the same as pericarditis as fluid accumulates due to pericardial inflammation, including infection, malignancy, trauma, iatrogenic, autoimmune, post-myocardial infarction, radiation, and renal failure. Although the treatment is pericardiocentesis or pericardial window, finding the etiology responsible for the development of pericardial effusion is important. Here, we describe the case of a 40-year-old female who presented to the emergency department with a chief complaint of severe epigastric pain of a two-day duration that was associated with multiple episodes of nausea, vomiting, dysphagia, and severe shortness of breath (New York Heart Association III). The patient was eventually diagnosed with cardiac tamponade as a cause of her dyspnea, as a two-dimensional cardiac echocardiogram detected a large pericardial effusion (>2 cm) with echocardiographic indications for cardiac tamponade with severe pulmonary hypertension. The patient underwent a therapeutic pericardial window with drainage of 250 mL of pericardial fluid. Ultrasound of the abdomen focusing on the kidneys showed an atrophic and echogenic right kidney with a bidirectional flow in the hepatic veins, suggestive of right heart failure. Subsequently, she underwent a kidney biopsy that showed diffuse mesangial proliferative glomerulonephritis with segmental sclerosing features consistent with IgA nephropathy, associated with tubular atrophy, interstitial fibrosis, interstitial inflammation, and moderate arteriosclerosis. The patient was diagnosed with stage V chronic kidney disease secondary to IgA nephropathy. IgA nephropathy is usually common in Caucasian or Asian males in their teens and late 30s, with hematuria as a usual presentation. This case is unique as cardiac tamponade with renal failure is rarely the presenting symptom of IgA nephropathy.

Calcitonin Gene-Related Peptide Antagonists as a Savior in Episodic and Chronic Migraine: A Review.

Headaches due to migraine are the second leading cause of disability in the world. Migraine can be classified as episodic migraine (EM) and chronic migraine (CM). The course of the disease starts from an aura followed by 4-72 hours of bouts of throbbing, mostly unilateral headache associated with nausea, photo/phonophobia with/without neurological deficit. The pathophysiology of migraine remains debatable and many drugs are used to help control migraine attacks with little or no benefit. However, patient compliance remains a reason for over and underdosing of these medications. The calcitonin gene-related peptide (CGRP), a vasoactive peptide is known to contribute to the disease course. Much work is done on antagonizing the receptor or the molecule itself. For this purpose, genetically engineered monoclonal antibodies are being utilized for long-term reduction in morbidity and prevention of migraine headaches. The four to name are: galcanezumab, fremanezumab, eptinezumab, and erenumab. The purpose of this review is to shed light on the use of these monoclonal antibodies, completed and recruiting trials, and the role of these medications in the prevention of not only EM and CM but also in medication overuse headaches.

Sensorineural Hearing Loss and Its Relationship with Duration of Chelation Among Major ß-Thalassemia Patients.

Introduction Thalassemia is a common genetic disorder worldwide, also occurring frequently in Karachi, Pakistan. Beta (ß)-thalassemia major patients need repeated transfusions which cause iron overload. Patients are treated with chelating agents to reduce the high serum ferritin level and to decrease morbidity and mortality due to increased iron levels. This combined therapy also leads to some complications. One of them is the sensorineural hearing loss (SNHL). To date, no data is available in Pakistan regarding SNHL among major ß-thalassemia patients on chelating therapy.  Methods A cross-sectional study was performed in collaboration with the Thalassemia Center and Dr. Ruth Pfau at the Department of Ear, Nose, and Throat, Civil Hospital, Karachi, Pakistan. The variable to detect hearing was pure tone air and bone conduction thresholds at the frequencies of 250 - 4,000 Hz. Clinical data, such as chelating agent dose, duration, and hearing status, were recorded. Demographic characteristics, like age, gender, height, and weight, were noted. The hemoglobin and serum ferritin levels of the subjects were also included. Results Forty-five percent of cases of thalassemia were suffering from SNHL. In the right ear, the Pearson correlation of chelating agent dose (mg) with SNHL was mildly positive and statistically significant (r = 0.261, p < 0.001), (r = 0.337, p < 0.001), (r = 0.198, p = 0.005), and (r = 0.207, p = 0.003) at the frequencies of 250, 500, 1,000, and 2,000 Hz, respectively, and the Pearson correlation of chelating agent used (in months) with SNHL was mildly positive and statistically significant (r = 0.232, p = 0.001), and (r = 0.301, p < 0.001) at frequencies 250 to 500 Hz, respectively. In the left ear, the Pearson correlation of chelating agent dose (mg) with SNHL was mildly positive and statistically significant, (r = 0.191, p = 0.007), (r = 0.202, p = 0.004), (r = 0.297, p < 0.001), (r = 0.183, p = 0.010) and (r = 0.221, p = 0.002) at frequencies 250, 500, 1,000, 2,000, and 4,000 Hz, respectively, and Pearson correlation of chelating agent used (months) with SNHL was mildly positive and statistically significant only at the frequency of 2,000 Hz (r = 140, p = 0.049).  Conclusion Chelation therapy and regular blood transfusions, apart from prolonging the life of thalassemic patients, also leads to some complications. With this survey, it was concluded that almost half of the patients had normal hearing, while the other half had sensorineural hearing loss after the use of deferasirox. It is inferred that the incidence of SNHL is not only dose-related but the duration of use of a chelating agent is also a contributing factor.

Role of Montelukast in Improving Quality of Life in Patients with Persistent Asthma.

Introduction Maintenance therapy of asthma has a crucial role in keeping the disease dormant and preventing frequent acute exacerbations. Asthma control may be achieved by inhaled corticosteroids (ICS) and/or long-acting beta-agonists (LABA). Leukotriene receptor antagonist - montelukast - may be added as an add-on to ICS/LABA or may also be given in monotherapy. The aim of this study was to evaluate the role of montelukast monotherapy as asthma control and its impact on the quality of life of these patients. Methods In this prospective, open-label, interventional study, montelukast 10 mg once daily was given to patients with mild to moderate persistent asthma for four weeks. Quality of life (QOL) was assessed on the Asthma Quality of Life Questionnaire - Standard (AQLQ-S) questionnaire. Asthma control was assessed on the Asthma Control Test (ACT). Data was entered and analyzed using SPSS version 23.0. Results On AQLQ-S, overall QOL improved with one month of montelukast therapy significantly. On sub-scales, except for emotional function, all other three sub-scales including symptoms, activity limitation, and environmental function improved significantly. Asthma control score also significantly improved with one month of montelukast therapy. Conclusion Montelukast has an effective role in asthma control and improvement of QOL in patients with mild to moderate persistent asthma.

Diagnostic Yield of Ultrasound-guided Trucut Biopsy in Diagnosis of Peripheral Lung Malignancies.

Introduction While computed tomography (CT) guided lung biopsy has been standard in histological diagnosis of pulmonary lesions, its use is limited to the interventional radiologists only. Ultrasound (US) guided biopsy of pulmonary lesions, which can be performed in-clinic by the pulmonologists only, is becoming a more popular technique. It also has the edge of real-time techniques, multi-planar imaging, and no radiation exposure to the patients. Methods This is a retrospective review of all the patients presenting with pleural-based lung lesions who underwent US-guided biopsy for diagnosis in the Department of Pulmonology, Liaquat University of Medical and Health Sciences Hospital, Hyderabad, Pakistan from 1st January 2013 till 31st December 2017. The diagnostic yield, sensitivity, specificity, and accuracy of US-guided biopsies were evaluated for diagnoses of peripheral lung malignancies. Results Ultrasound-guided biopsies for lung lesions has a diagnostic yield of 88.3%, sensitivity of 95.80%, and specificity of 90% with an accuracy of 95.35%. Pneumothorax as an immediate complication was seen only in 1.5% cases. Conclusion US-guided biopsies are a much safer diagnostic alternative to CT-guided biopsy for lung lesions and have high diagnostic yield. It doesn't require special radiological interventionists, can be performed at patients' bedsides, and the equipment is not as expensive.
