    Abstract Protein C (PC) and protein S (PS) are natural anticoagulants that protect the body against thrombosis, and their deficiency, either inherited or acquired, renders the body to a hypercoagulable state. This leads to venous thromboembolism manifesting as thrombosis, pulmonary embolism and superficial thrombophlebitis among other causes. The involvement of arteries is rare and has been explained by only a few studies. Hence, the presentation of PC and PS deficiencies with stroke and myocardial infarction (MI) is rarely observed, especially in young patients. We report a case of a 33-year old male with a past medical history of stroke and MI for which no underlying cause was found. He presented now with shortness of breath and left-sided chest pain and after a series of workup, eventually diagnosed as a rare case of PC and PS deficiencies.

    Abstract Hereditary thrombophilia (HT), including the mutation of factor V gene and the deficiency of proteins C, protein S, or antithrombin, is a risk factor for portal vein thrombosis (PVT). PVT in acute cases is usually asymptomatic, whereas chronic cases mostly present as variceal bleeding and splenomegaly. However, cavernous transformation of the portal vein secondary to a long-standing PVT is very rare. Here we present a case of a 28-year-old female who was admitted with complaints of left upper abdominal pain and swelling for four to five years. Using laboratory and radiological examinations, a confirmatory diagnosis of cavernous transformation of a thrombosed portal vein due to protein C and S deficiency was made. The patient was managed through splenectomy with splenorenal shunting along with life-long prescription of anticoagulants.

    Abstract Remimazolam is made by combining midazolam and remifentanil as an alternative to conventional sedatives. To evaluate the efficacy of remimazolam for sedation in patients undergoing colonoscopy, we conducted a systematic review and meta-analysis of the available randomized controlled trials (RCTs) comparing remimazolam and midazolam. A search was conducted using PubMed, Cochrane Library, and clinicaltrial.gov from inception till December 26, 2021, for RCTs that investigated the efficacy of remimazolam during the above-mentioned procedure. There was no restriction of language. A quality assessment was performed using the Cochrane Risk-of-Bias tool. The data were pooled, and a meta-analysis was completed. The systemic review was conducted in accordance with the Preferred Reporting Items for Systemic Reviews and Meta-Analysis (PRISMA) guideline statement. Three randomized controlled trials involving 539 patients were included in the meta-analysis. Compared with midazolam during colonoscopy, remimazolam results in reduced need for top-up doses (RR= 3.45, 95% CI=1.07 to 11.14; P=0.04, I

    Abstract Since its origin in China, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has become a pandemic and spread to 209 countries. As coronavirus disease 2019 (COVID-19) is a very rapidly emerging disease, organ-specific studies related to it have been reported. Apart from respiratory findings, some studies have highlighted inflammatory consequences in the heart, kidney, and/or liver as well. Cardiac involvement in COVID-19 seems to be a result of an inflammatory storm in response to the infection. Moreover, direct viral invasion of cardiomyocytes, as well as a myocardial injury due to oxidative stress, may account for acute cardiac injury in COVID-19. Nevertheless, the mechanism of heart injury in COVID-19 is not clear yet. However, multiple studies that highlight the clinical features, laboratory findings, and prognosis of acute myocardial injury (AMI) in COVID-19-affected individuals have been published. In this review, we have summarized the findings of all those studies as well as the clinical features and management of cardiac injury discussed by some case reports.

    Abstract Postural orthostatic tachycardia syndrome (POTS) is an autonomic disorder characterized by symptoms such as palpitations, dyspnea, chest discomfort, and lightheadedness affecting various systems. The pathophysiology of POTS is not completely understood due to a variety of symptoms showing that the disease is multifactorial. There is no approved uniform management strategy for POTS and hence, no drug has been approved by the United States (US) Food and Drug Administration (FDA) for it. Ivabradine is an FDA-approved drug for stable symptomatic heart failure (HF) and patients with an ejection fraction (EF) of ≤35%. Previous studies have depicted improvement in symptoms of POTS with the use of ivabradine. It is a selective inhibitor of funny sodium channels (I

    Abstract Biotinidase deficiency (BTD) is a rare yet treatable metabolic autosomal recessive (AR) disorder in which the body is unable to recycle the vitamin biotin. Early diagnosis and treatment can be life-saving, but some symptoms of the disease are irreversible, and the condition can even prove to be fatal if not correctly diagnosed and managed. Here we present a case of a six-month-old child who presented with cough, fever, and difficulty in breathing. Respiratory examination revealed deep subcostal and intercostal recessions, bilateral crepitations, and wheezes. On central nervous system (CNS) examination, the baby had a low Glasgow Coma Scale (GCS) score of 10 while the tone was decreased, and bulk was increased in all four limbs. Chest X-ray revealed haziness at the right middle and lower lobes. Antibiotics were started keeping pneumonia, bronchiolitis, and sepsis in mind along with an initial diagnosis of inborn error of metabolism (IEM). As the patient's condition deteriorated, nasal bubble continuous positive airway pressure (CPAP) and nebulization were provided and later put on a ventilator. Arterial blood gases (ABGs) showed severe metabolic acidosis and compensatory respiratory alkalosis with an anion gap of 15. Urine profile for organic acid was performed, and the diagnosis of sepsis with BTD was made. Unfortunately, our patient expired on the fourth day of admission before a biotin injection could be searched and administered. Moreover, our patient was also suspected of a possible Sotos syndrome, which is a rare genetic disorder characterized by excessive growth in the initial years of life. The case highlights the significance of the diagnosis of such metabolic disorders in the natal period of life and their immediate management.

    Abstract Osteopetrosis comprises a group of rare inherited disorders of the bones characterized by a common radiographic finding of increased bone thickness. The disorders vary genetically as well as clinically, and range in severity from mild manifestations to fatal complications based on the type of the disorder. Malignant infantile osteopetrosis (MIOP) is a less common, more severe form of the disease with most affected individuals surviving up to only the first few years of life if left untreated. We present a previously diagnosed case of the malignant infantile type who was brought to our attention for convulsions. Antiepileptic medications were started along with supportive therapy. CT scan revealed a large frontal lobe hemorrhage, which was suspected as a possible cause of the seizures, other than the progressively worsening hypocalcemia. Laboratory investigations also revealed pancytopenia and blood cultures positive for staphylococci, which were treated accordingly. Genetic testing and hematopoietic stem cell transplantation could not be performed due to financial constraints and the rapidly deteriorating condition of the patient. Unfortunately, the baby expired two weeks from the day of admission. This case highlights a rare and grave clinical manifestation of MIOP and brings to attention the significance of bone marrow transplantation as the only curative therapy of the disease.

    Abstract Protein C (PC) is a 62-kD vitamin K dependent glycoprotein produced by the liver as a zymogen and is activated by binding to the thrombin-thrombomodulin complex, with protein S (PS) acting as a cofactor. Among its various functions, PC acts as a naturally occurring anticoagulant and its deficiency, either homozygous or heterozygous, predisposes the individual to a state of thrombosis, particularly venous thromboembolism, and mainfests as myocardial infarction (MI), deep venous thrombosis, pulmonary embolism, or stroke. This review discusses the pathophysiology of the anticoagulatory effect of PC, mode of inheritance of its deficiency, the arterial and venous involvement in patients with stroke, and its risk factors. A detailed analysis of published case reports on PC deficiency as a causative agent of stroke in young adults has also been included along with the management of such patients.

    Abstract Nonketotic hyperglycinemia (NKH) is an autosomal recessive disorder caused by a defect in glycine cleavage enzyme. It leads to the accumulation of glycine in the body tissues, blood, and cerebrospinal fluid (CSF). Most NKH cases are diagnosed during the natal period of life and are fatal if not promptly diagnosed and managed. Here we present a case of a two-day-old child who presented with reluctant feeding and lethargy. She had reduced tone in all four limbs and a Glasgow Coma Scale score of 9. Keeping an infectious etiology in mind, she was started on cefotaxime and amikacin. The patient was shifted to the neonatal intensive care unit; however, no improvement in the patient's condition was seen and antibiotics were changed to linezolid and meropenem along with initiation of acyclovir. The patient's blood and CSF cultures were negative. Serum amino acid chromatography showed elevated levels of glycine, and a diagnosis of NKH was made. The patient was managed symptomatically but expired on the 22nd day of admission. The case highlights the importance of prompt diagnosis and management of aminoacidopathies. Nearly all metabolic disorders have similar clinical presentations, and an early diagnosis can improve the outcome in patients.
