Successful treatment of community-acquired methicillin-resistant Staphylococcus aureus purulent myopericarditis

A previously healthy 48-year-old active duty man, who had been treated for an elbow abscess 3 weeks earlier, presented to an emergency department in Bahrain with tachycardia, pericardial friction rub and jugular venous distention. Cardiac tamponade was confirmed on transthoracic echocardiogram and he was taken for emergent pericardiocentesis. Pericardial fluid cultures grew community-acquired methicillin-resistant Staphylococcus aureus. Despite ongoing treatment with intravenous vancomycin, he developed a recurrent fibrinous pericardial effusion and constrictive pericarditis requiring pericardiectomy. Though he initially did well postoperatively, he developed drug reaction with eosinophilia and systemic symptoms syndrome in response to vancomycin. He was transitioned to ceftaroline and started on high-dose steroids. He recovered during a week-long admission and was discharged home. Several weeks later at follow-up he was doing well and had resumed moderate intensity exercise.

Unusual complications from amitriptyline intoxication

Althoughtricyclic antidepressants(TCAs) are frequently prescribed to patients with depression, these drugs can also be misused. A 21-year-old comatose patient was referred to our hospital presenting with ventricular tachycardia. Despite initial treatment including intravascular lipid emulsion, ventricular fibrillation occurred soon after arrival. Venoarterial extracorporeal membrane oxygenation and therapeutic hypothermia were administered. Refractory arrhythmia disappeared on the next day. A high concentration of amitriptyline was identified in his blood samples on arrival. Mechanical bowel obstruction followed after abdominal compartment syndrome caused by anticholinergic effects, and refractory seizure occurred due to TCA intoxication. Although seizure was brought under control with anticonvulsant agents, his Glasgow Coma Scale did not recover to the full score. MRI presented irreversible damage to the bilateral frontal lobe and insula. Amitriptyline has the potential to cause unusual serious complications, such as abdominal compartment syndrome, irreversible central nervous system disability and lethal arrhythmia.

Elizabethkingia meningoseptica: emerging multidrug resistance in a nosocomial pathogen

A 46-year-old male patient presented with complaints of burning micturition for 2 days. Initial history, physical examination and laboratory investigations were consistent with the diagnosis of congestive cardiac failure (CCF) and concomitant urinary tract infection. CCF was treated with diuretics and a urine culture/sensitivity (C/S) was sent which returned growing Elizabethkingia meningoseptica resistant to all tested drugs. Intravenous cefotaxime which had been started empirically 3 days earlier was withheld at this point, and a repeat urine C/S was sent revealing resistance to all tested drugs (including reserved drugs) barring minocycline. The patient was treated with oral minocycline for 14 days after which he was symptomatically better with sterile urine. The patient was subsequently discharged.

Balance versus hearing after cochlear implant in an adult

The effect of vestibular rehabilitation (VR) on anxiety, dizziness and poor balance that developed after cochlear implant (CI) surgery is described. A 54-year-old woman, with profound hearing loss since the age of 2 years, underwent right CI surgery 2 years previously. On implant activation, the patient immediately felt dizziness and imbalance, which affected the ability to perform activities of daily living and increased anxiety to where the patient considered the CI removal. Prior to VR the patient was evaluated with the Dizziness Handicap Inventory and the Visual Vertigo Dizziness Questionnaire and clinically with the Zur Balance Scale and Video Head Impulse Test. The patient underwent 14 VR sessions over 4 months that included compensation, adaptation and habituation exercises. After VR the patient was able to maintain good balance while using the CI. Dizziness and anxiety improved dramatically. This report increases awareness that a CI could compromise balance, which can be overcome with personalised VR.

Acute pancreatitis as an unusual presentation of primary splenic lymphoma

A 51-year-old man with no relevant medical history presents to the emergency department complaining of a recent worsening of few months upper abdominal pain with back radiation and postprandial fullness, without B symptoms. Laboratory analysis showed hyperamylasaemia, elevated lactate dehydrogenase and inflammatory parameters. Abdominal ultrasonography revealed a heterogeneous solid mass in the spleen/splenic hilum with pancreatic parenchyma continuity and no biliary tract dilation or gallstones. A mild acalculous acute pancreatitis diagnosis was made. Abdominopelvic CT revealed a large heterogeneous mass infiltrating the spleen and pancreas and obstructing the common bile duct at the pancreatic level with upstream dilation of biliary and pancreatic ducts, with splenic vein invasion. Several necrotic, peripancreatic and hepatic hilar adenopathies were also observed. Ultrasound-guided biopsy showed a primary splenic diffuse large B-cell non-Hodgkin's lymphoma. Chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone) was performed with lack of response and the patient died within 10 months of diagnosis onset.

Colonic gallstone ileus

Gallstone ileus is a rare aetiology of bowel obstruction and very infrequently occurs in the colon. Typically, colonic gallstone ileus carries a high morbidity and mortality and requires surgery. This case report describes a cholecystocolonic fistula in a patient with ulcerative colitis with resulting colonic gallstone ileus, which was successfully intervened on via an endoscopic approach.

Paediatric case of ductal origin of right pulmonary artery presenting with exertional dyspnoea and mimicking asthma and primary ciliary dyskinesia

Ductal origin of pulmonary artery is a rare anomaly that is frequently misdiagnosed. Patients may present with exertional dyspnoea, recurrent respiratory infections and pulmonary hypertension. The presence of pulmonary hypertension can adversely affect clinical outcome in these patients; hence, early identification and intervention is the key to improve survival. A case of a 3-year-old child presenting with exertional dyspnoea is presented in this report. Chest radiograph revealed right-sided pulmonary hypoplasia and mediastinal shift to the right. Pulmonary artery agenesis was suspected when CT of the chest demonstrated right-sided pulmonary artery agenesis. Cardiac catheterisation revealed the correct diagnosis of ductal origin of right pulmonary artery. The most striking feature of this case is that the clinical presentation is mild compared with the findings on imaging.
