An alliance of established experts on critical care, Front Line COVID-19 Critical Care Alliance (FLCCC), has published two protocols for treatment of COVID-19. The first one, methylprednisolone, ascorbic acid, thiamine, and heparin (MATH+), is intended for hospital and intensive care unit treatment of pulmonary phases of the disease. It is based on affordable, commonly available components anti-inflammatory corticosteroids (methylprednisolone, "M"), high-dose vitamin C infusion (ascorbic acid, "A"), vitamin B1 (thiamine, "T"), anticoagulant heparin ("H"), antiparasitic agent ivermectin, and supplemental components ("+") including melatonin, vitamin D, elemental zinc, and magnesium. The MATH+ protocol has received scarce attention due to the World Health Organization (WHO) advising against the use of corticosteroids in the beginning of the pandemic. In addition, randomized controlled clinical trials were required as a condition for adoption of the protocol. As the hospital mortality rate of MATH+ treated patients was approximately a quarter of the rate of patients receiving a standard of care, the authors of the protocol considered performing such trials unethical. Other parties have later performed clinical trials with corticosteroids and anticoagulants, which has led to a more widespread adoption of these components. In October 2020, ivermectin was upgraded from an optional component to an essential component of the protocol. According to the authors, ivermectin is considered the first agent effective for both prophylaxis (prevention) of COVID-19 and for treatment of all phases of COVID-19 including outpatient treatment of the early symptomatic phase. Therefore, at the end of October 2020, a separate ivermectin-based I-MASK+ protocol for prophylaxis and early outpatient treatment of COVID-19 was published.A 78-year-old man fell from a ladder and suffered a right distal tibial fracture. On the seventh day after injury, he developed a low-grade fever and was isolated in a private room. Polymerase chain reaction for COVID-19 was positive (day 4 from the day of saliva sampling). https://www.selleckchem.com/products/ak-7.html On day 5, he required 1 liter per minute of oxygen and dexamethasone therapy was initiated. On day 6, his D-dimer level was 25.0 μg/mL, and continuous infusion of heparin was initiated. From day 7, he was administered remdesivir. On day 9, his oxygenation suddenly showed a remarkable deterioration. He received a tentative diagnosis of COVID-19-induced pneumonia accompanied by severe acute respiratory distress syndrome (ARDS) and underwent urgent tracheal intubation and mechanical ventilation. He also received intravenous immunoglobulin (IVIG) and was also administered glycyrrhizin. His oxygenation gradually improved and extubation was performed on day 15. Following rehabilitation, he did not require oxygen on day 19. On day 20, his D-dimer level was found to be increased and enhanced computed tomography revealed pulmonary embolism. He was prescribed a direct oral anticoagulant. On day 28 he was transferred to a general ward for rehabilitation. These unspecific antiviral therapies and immune modulation therapy may be useful treatments for the main cause of ARDS, which may explain the favorable outcome that was obtained in the present case.This is a case of a 71-year-old smoker man who presented with four days of gross hematuria, which turned to be caused by eosinophilic cystitis (EC) proven by bladder biopsy. EC is a rare clinical and pathological inflammatory condition of the bladder with an unknown exact cause. It can present with hematuria, urinary frequency, dysuria, and suprapubic pain. Sometimes, the presentation can mimic urinary tract infection (UTI) or malignancy, especially in older patients.Ganglioneuromas (GNs) are benign, differentiated tumors that are derived from neural crest sympathogonia. They can be found anywhere in the body along autonomic ganglia. These tumors are seen most often in individuals over 10 years of age and are usually asymptomatic. However, GNs can grow large and cause symptoms due to mass effect. GNs are rarely located within the suprarenal gland and are benign tumors that are often diagnosed late in their course due to mass effect or found incidentally on imaging studies. We describe a case of a 22-year-old female who presented to clinic with vague abdominal pain. She underwent an extensive workup which ultimately revealed a rare presentation of a left suprarenal GN that required surgical removal. She underwent an extensive workup which ultimately revealed a left suprarenal GN that required surgical removal. The patient underwent laparotomy and surgical excision of the mass and made a full recovery.Fibrinogen is a precursor of fibrin, which acts as a procoagulant plasma soluble protein. It is involved in blood viscosity and clot stability to help in the recovery of damaged blood vessels. We describe the case of a preterm newborn who presented with abdominal distension and manifestations of bleeding in venipuncture sites. In the initial laboratories, prolonged coagulation times were observed with a decreased concentration of fibrinogen. This newborn had transfusion support, with recovery in factor levels and a subsequent decrease in them. Based on this trend and ruling out other possible causes of hypofibrinogenemia, such as liver disease, sepsis, or disseminated intravascular coagulation, the diagnosis of congenital hypofibrinogenemia was made. This case report includes the diagnostic and therapeutic approach of an unusual hemorrhagic presentation in the newborn, highlighting the need for transfusion and dynamic fibrinogen replacement to prevent complications and seek rapid improvement in symptoms.Perforated diverticulitis presents a challenging clinical scenario for the surgeon. Development of an abscess in those without an acute abdomen may be amendable to non-operative drainage. Furthermore, early intervention can dramatically alter the hospital course let alone the overall outcome. While relatively safe as a procedure, image-guided drainage does carry risk that needs to be calculated relative to benefit gained. One rare albeit possibly serious risk is pseudoaneurysm formation.
