H1N1 influenza A. Preliminary evaluation in hospitalized patients in a secondary care facility in Saudi Arabia

To assess the epidemiologic and clinical manifestations of the first wave of H1N1 influenza A patients. This study is a retrospective chart review of all patients admitted in King Saud Medical Complex, Riyadh, Kingdom of Saudi Arabia, from 22nd May to 31st August 2009, with a proven diagnosis of H1N1 influenza A. Only patients with a positive nasopharyngeal swab were included, and excluded when the swab was negative. Charts were then analyzed for epidemiological and clinical data. A total of 153 patients with proven H1N1 infection were admitted, with a predominance of male patients [108 [71%]]. Most patients were Saudis [111 [73%]], with 83 males [75%], and 28 females [25%]. The mean age was 25 years [standard deviation; 9.45 years], and median age was 24 years. The most common symptoms in order of frequency were; fever [143 patients], cough [126 patients], sore throat [70 patients], headache [18 patients], shortness of breath [17 patients], myalgia [11 patients], diarrhea [9 patients], and vomiting [7 patients]. Average duration of symptoms before admission was 3.55 days, and the average time of hospitalization was 4.8 days. Full recovery was obtained in 150 patients. Death occurred in 3 patients. True to its designation as a pandemic, H1N1 influenza A, has reached Saudi Arabia and poses a risk to the young population without immunity, and those with co-morbid disease, particularly of the lungs [bronchial asthma], and the pregnant. Despite its virulence in infecting people, deaths are far less than anticipated for such a novel virus. Social distancing can be recommended. However, further observation has to continue to substantiate these tentative preliminary findings

Nalidixic acid-resistant Salmonella enterica serotype typhi infection presenting with sub-intestinal obstruction and mesenteric adenitis

Nalidixic acid-resistant Salmonella typhi NARST infections increase minimal inhibitory concentrations of fluoroquinolones, due to chromosomal mutations in the gene encoding DNA gyrase, and can lead to a delayed treatment response. This in turn alters the course of the disease allowing for a protracted period of illness and the occurrence of complications. In this case report, we present a patient from the Indian sub-continent, who was diagnosed with NARST complicated by sub-intestinal obstruction, her diagnosis, treatment, and subsequent recovery

Spinal intramedullary cavernous hemangioma

The spinal cord can be involved in a variety of disease processes. These can be congenital or acquired. An acute onset of symptoms usually allows a defined set of causes to be considered including trauma, ruptured vascular anomalies, demyelination, and myelitis. Intramedullary cavernous hemangioma of the spinal cord is a congenital or acquired vascular malformation, and one of the rare causes of hematomyelia. We present such a case, and discuss the symptoms, diagnosis, and suggested best treatment options based on a review of present day literature

Neurosyphilis in a young Indian expatriate

Neurosyphilis is the infection of the central nervous system with treponema pallidum species, and true to its reputation as the old mimic, can present with a multitude of clinical scenarios, one of which is stroke in the young. Rare in developed countries, except for an at-risk population of drug abusers and HIV infected patients; it is still common in the rest of the world. We describe the case of a young Indian male, his presentation, diagnosis and treatment, and remarkable recovery on aqueous penicillin G therapy following his presentation with a stroke

Thrombolytic therapy in acute pulmonary embolism due to heparin-induced thrombocytopenia type II

Hospitalized patients are in danger of deep venous thrombosis either due to a genetic tendency, immobilization or the underlying medical condition. Paradoxically heparin, the substance used to prevent this complication, can lead to thrombo-embolic phenomena, which can be life threatening. We report a case of heparin-induced thrombocytopenia, which caused a massive pulmonary embolism, and its management by administering a thrombolytic agent in a situation where bleeding seems inevitable

Resolution of a large left ventricular thrombus with anticoagulation alone

Dilated cardiomyopathy and the resultant left ventricular dysfunction are risk factors for thrombus formation in the heart, reflecting the intimate relationship between structure and function in this vital organ. Once formed, depending on size, location, and mobility, left ventricular thrombi have the tendency to embolize, sometimes with dire consequences. Proper management of these thrombi is still controversial. We present a case of an unusual large thrombus, which resolved with anticoagulation therapy alone, giving hope that more invasive intervention can safely be circumvented

Traumatic fat embolism syndrome

Traumatic fat embolism syndrome occurs most often following fractures of long bones sustained in road traffic accidents and is a common cause of medical consultation from the orthopedic surgery department. The sub-clinical presentation is subtle and expresses itself by the presence of hypoxemia, while the full clinical syndrome compromises respiratory insufficiency, an altered consciousness and a characteristic petechial rash. Recognition is simple once the patient is viewed in the context of his or her clinical setting. Diagnosis is aided further by the presence of hematological and biochemical abnormalities including anemia, thrombocytopenia, an elevated erythrocyte sedimentation rate and fat macroglobulinemia. Imaging by chest radiograph, computed tomography or magnetic resonance of the brain is used to confirm the extent of the respective organ involvement and to exclude alternative pathologies. The release of free fatty acids into the circulation and their subsequent effects is the key pathological event. Treatment is based on supportive care and high-dose corticosteroid therapy. We report a patient with traumatic fat embolism syndrome who developed the syndromes classical symptoms and signs following fracture of the long bones of his left lower leg. Admission to an intensive care unit, mechanical ventilatory support with positive end-expiratory pressure and corticosteroid therapy lead to his improvement and allowed eventual open reduction and internal fixation and discharge of our patient. Modern therapy offers a relatively good prognosis for patients with traumatic fat embolism syndrome; the optimal dose and timing of corticosteroid therapy in prophylaxis and treatment however, remain the subject of intense debate

Combined Brucella Melitensis and Streptococcal Viridans Endocarditis

Infectious endocarditis is a potentially lethal inflammation of the hearts' inner lining invaded by microorganisms. The mortality from this illness increases as the number of infective organisms rises to 2, due to involvement of the left side of the heart. These microorganisms usually arise from the patient's own flora but can be acquired from the environment. Fever and heart murmurs are the principal clinical manifestations followed by a plethora of peripheral signs due to dissemination of microorganisms via the bloodstream. Echocardiographic imaging and sensitive culture techniques form the cornerstone of diagnosis. We report a patient with rheumatic heart disease who had combined brucella melitensis and streptococcus viridans endocarditis complicated by heart failure and an aortic root abscess. He was diagnosed on the basis of a history of prolonged fever and occupational risk as a shepherd, the presence of heart murmurs, positive blood cultures and echocardiographic evidence of aortic vegetations. He had an excellent response to intravenous antibiotic therapy combined with aortic valve replacement, which nowadays is regarded as the safest therapeutic approach for aortic valve endocarditis
