Introduction Complicated malaria is a medical emergency with a high mortality if untreated. Aim To describe the clinical spectrum, treatment practices and outcome of severe malaria cases admitted to an intensive care unit. Method Thirteen severe malaria cases admitted to the ICU over a 6 years period (2012 – October 2018) were included. The data was retrospectively extracted from the hospital patient data management system. Results Nine patients had P. falciparum malaria, three had P.Vivax, and one had both. Only one had received malarial chemoprophylaxis. The median time of attending to medical health facility after symptoms started was 7 days (range: 2–21 days). All cases responded to antimalarial therapy and supportive management. Complications included shock 54%, kidney failure 38%, respiratory failure 69%, cerebral malaria 61%, hypoglycemia 23%, coagulation derangement 8%, and acidosis 23%. There were no fatal outcomes but one case had permanent brain damage and the rest recovered completely. Conclusion The median treatment delay of seven days explains why these patients ended in intensive care with multiple symptoms of severe malaria and often multiorgan failure. Pretravel advice and use of malaria chemoprophylaxis when visiting high risk areas would probably have prevented infection and timely attendance to healthcare once symptomatic would have reduced the morbidity associated with infection, reduced length of stay in hospital and hence resources.
Objectives: Liver abscess can develop as a complication of hepatobiliary disease or other intraabdominal infections, but more recently it is associated with primary and secondary liver malignancies and their treatment. The goal of this study was to analyze the epidemiology, etiology and clinical characteristics of pyogenic liver abscess in Oman. The intention was to obtain the information needed for the adequate liver abscess empirical treatment. Methods: This retrospective study took place in a tertiary hospital. Consecutive patients treated for the liver abscess during the five years period, from January 2013 until the end of 2017, were enrolled. Their demographic and clinical data were used to study the characteristics of pyogenic liver abscess in Oman. Results: Fifty-three patients with pyogenic liver abscess were enrolled in the study. They were predominantly male and younger than 60 years. Klebsiella pneumoniae was the most usual bacteria causing the liver abscess. Clinical presentation was unspecific and the abdominal pain and high fever were the most usual symptoms. Conclusion: The majority of pyogenic liver abscesses are caused by K. pneumoniae so the empirical treatment should be started with antibiotic directed against it. Further studies are needed to establish the local role of anaerobic bacteria in pyogenic liver abscess as well as to monitor the presence of hypervirulent K. pneumoniae in Oman. Keywords: Pyogenic liver abscess; Etiology; Epidemiology; Klebsiella pneumoniae.
Adverse reactions to radiocontrast media (RCM) are rare and occur predominantly in association with intravenous administration but may also occur with intra-arterial and nonvascular injections (e.g., retrograde pyelography, intra-articular injections) of RCM. This article reports the case of a 52-year-old lady who was known to have amyloidosis secondary to rheumatoid arthritis and was on regular renal replacement therapy. She was under follow-up for regular angioplasties to manage the central vein stenosis that was affecting her right brachiocephalic arteriovenous fistula (AVF) and was referred to our Immunology service when she developed an allergic reaction after her AVF angioplasty (central venoplasty). Despite being dialysed immediately post-angioplasty, she complained of skin rash and itching with hoarseness of voice that developed almost six to eight hours post-angioplasty. We decided to arrange the iodinated nonionic iso-osmolar contrast agent iodixanol (Visipaque™) for her instead, as it is known to be better tolerated in patients with reactions to Omnipaque™ due to its lower osmolarity as compared to Omnipaque™. However, since it was the first time to request this contrast in our hospital, it was not possible due to logistical reasons. It was necessary that our patient continued to undergo angioplasty every three months, however, she was developing more severe and earlier symptoms with each subsequent exposure to the radiocontrast medium. After her latest reaction of generalized itching and angioedema with shortness of breath during the procedure despite premedication, it was decided for her to undergo desensitization to Omnipaque™. In the absence of a published protocol for this, we used a protocol used for desensitization to Visipaque™. She showed an excellent response and completed her remaining angioplasties until Visipaque™ became available. Hence, desensitization to Omnipaque™ using the published protocol to Visipaque™ is likely to help patients allergic to Omnipaque™ or where Visipaque™ is not available or non-affordable in low/middle-income countries.
Liver dysfunction in the presence of Systemic Lupus Erythematosus (SLE) can be caused by many factors including drug-induced, SLE itself, fatty liver, Autoimmune Hepatitis (AIH), primary biliary cirrhosis, cholangitis, alcohol or viral hepatitis. However, Lupus hepatitis and autoimmune hepatitis are two distinct immunological conditions involving the liver, which can have similar clinical, laboratory and systemic presentations, leading to difficulties in diagnosis [1,2].
Eosinophilic fasciitis (EF) is a rare systemic inflammatory disease with an unknown etiology. Making a diagnosis in such a case is always a challenge as it is a rare disease and mimics scleroderma and scleroderma-like syndrome but should be kept in mind as it carries a high mortality. Furthermore, it is a treatable disease. Here, we report a 41-year-old woman who presented to the rheumatology clinic at the Royal Hospital, Muscat, Oman, with a one-month history of bilateral swelling of the forearms along with skin tightness and fingers contraction. Her history and physical examination along with histopathological examination and magnetic resonance imaging findings were consistent with EF. She showed an excellent response to steroids and methotrexate which is not a combination therapy that has been tried or mentioned previously.
Scrub typhus is a potentially fatal rickettsial infection caused by Orientia tsutsugamushi . It is an obligate intracellular Gram-negative bacterium transmitted by the bite of infected chigger larva. The disease is distributed from Asia to the Pacific islands, and this region is known as the Tsutsugamushi Triangle. A 28-year-old man was admitted to the Royal Hospital with a four-day history of fever, headache, rigors, anorexia, and a nonspecific macular rash. Clinical presentation, laboratory results as well as epidemiological data indicated that this might be a case of scrub typhus. Additional serology tests confirmed the presumed diagnosis, and the patient was successfully treated with empirical therapy. Untreated scrub typhus has high mortality and early diagnosis and adequate treatment can prevent the potentially fatal outcome of the disease.
Anaphylaxis is an acute, life-threatening immediate allergic reaction caused by the sudden systemic release of mediators from mast cells. This study aims to assess the current practice of emergency management of children and adults diagnosed with anaphylaxis at the Royal Hospital, Muscat, Oman, in line with the National Institute for Health and Clinical Excellence (NICE) guidelines. MethodsThis is an observational retrospective study of all anaphylaxis cases seen at the emergency department (ED) from January 2013 to January 2018 and compared with the management of anaphylaxis in the ED as per the NICE guidelines. Inclusion criteria were all patients, children (age 16 and below), and adults diagnosed with anaphylaxis based on the World Allergy Organization (WAO) criteria. Exclusion criteria are all cases labeled as anaphylaxis that did not match the WAO criteria for anaphylaxis. ResultsOf 100 patients with a preliminary diagnosis of anaphylaxis, 49 patients (49%) were true-anaphylaxis cases based on the WAO definition 16 were children (age 16 years and below), and 33 were adults ( age 16 years and above). The other 51 patients (51%) with misdiagnosed anaphylaxis were later diagnosed with spontaneous urticaria, septic shock, vocal cord dysfunction, severe asthma, and anxiety attack. All 49 patients with true-anaphylaxis appropriately received adrenaline intramuscularly at the ED. All 16 children were admitted, seen by an allergist, and received an adrenaline auto-injector when indicated. Only 5 of the 33 adults were admitted and seen by an allergist, and 4 of those required an adrenaline auto-injector upon discharge. The remaining 28 adults were discharged from the ED, and only 3 of these were referred to the allergist. None received an adrenaline auto-injector upon discharge from the ED, and no mention in the ED notes on patient education regarding allergen avoidance. ConclusionThird of the patients who presented to ED were children (<16 years), and two third were adults. Insect venom was the main reason for anaphylaxis in both age groups. There was an underutilization of adrenaline autoinjector prescriptions for adult patients. This could be very well improved by disseminating policies and guidelines to adult physicians.
