In a 49-year-old male with fever, dyspnea, and chest pain, thoracic x-ray revealed pneumonia with enlarged heart silhouette. Antibiotics were successful, pneumonia healed and complaints disappeared. Yet, during the following 3 months, echocardiography showed mild persistent pericardial effusion while in ECG both sinus tachycardia and ST-T changes were found suggesting chronic pericarditis. Magnetic resonance imaging, however, revealed an extensive posterobasal aneurysm with pericardial effusion substantiated by ventriculography. Coronary angiography showed diffuse three-vessel disease. Surgery revealed aneurysm with distinct perforation of the left ventricle and pericardial thrombi, thus aneurysmectomy as well as bypass grafts were performed. One year postoperatively, magnetic resonance imaging confirmed the absence of aneurysm with only a small irreversible posterobasal perfusion defect remaining as shown by thallium scintigraphy.

A patient with ulcerative colitis developed eosinophilic pneumonia, sinus tachycardia, skin rashes, headache and insomnia following treatment with Salazopyrin. The pneumonia as well as the other side effects resolved spontaneously following discontinuation of the drug and reappeared when Salazopyrin was readministered.

The clinical course is described of a 28-year-old woman who was severely ill following ingestion of a Do-Do tablet (which consists of ephedrine, caffeine and theophylline), 24 h after discontinuing phenelzine treatment. Signs and symptoms were delayed for 8 h after which she developed encephalopathy, neuromuscular irritability, hypotension, sinus tachycardia, rhabdomyolysis and hyperthermia. Her illness was complicated by pneumonia and adult respiratory distress syndrome (ARDS). The management of monoamine oxidase inhibitor (MAOI) toxicity, which can arise from interactions and overdoses, is discussed. It should be remembered that, despite the increase in use of alternative and safer antidepressants, MAOI interactions still occur and unless they are managed appropriately, are potentially fatal. Patients need to be warned that restrictions apply for up to 2 weeks after stopping the medication, and doctors need to be aware that serious interactions can occur in this time period.

From January 1, 1978 to December 31, 1992, 37 patients underwent a completion pneumonectomy after a previous lobectomy (36 men and 1 woman; mean age, 60 years; range, 41 to 77 years). These account for 4.8% of 758 pneumonectomies. The purpose of the present study was to evaluate the operative results of completion pneumonectomy and long-term survival in patients with bronchogenic cancer. The initial lung resection had been performed for primary bronchogenic cancer in 23, metastatic thyroid adenocarcinoma in 1, and benign diseases in 13 (tuberculosis in 11, aspergilloma in 1, and bronchiectasis in 1). Completion pneumonectomy was required for bronchogenic cancer in 32 (15 stage I, 6 stage II, 11 stage III). One patient had relapsing metastatic thyroid carcinoma, 2 had bronchiectasis, and 2 had a venous infarction after lobectomy. Four patients (10.8%) died perioperatively of the following causes: 1 fatal intraoperative bleeding, 1 fatal postoperative bleeding, 1 pneumonia, and 1 malignant hypercalcemia. Median operative blood loss was 1,000 mL, and 19 patients experienced bleeding exceeding 1,000 mL (51%). Six patients had intraoperative vascular injury. Nonfatal surgical complications occurred in 9 patients (24%), including 5 clotted hemothoraces, 3 empyemas, and 1 bronchopleural fistula. Four patients had medical complications (2 pulmonary edemas, 1 sinus tachycardia, and 1 unexplained fever). Twenty-three had an uneventful straightforward recovery (62%).(ABSTRACT TRUNCATED AT 250 WORDS)

Diaphragmatic paralysis (DP) due to phrenic nerve paralysis is a rare complication after cardiac surgery. A 48-year-old male patient developed respiratory insufficiency, tachypnea, sinus tachycardia, chest pain, pneumonia, and fever immediately after coronary artery bypass grafting. Paradoxical movement of the epigastrium was noted during spontaneous ventilation and the chest X-ray showed elevation of the left hemidiaphragm. The diagnosis of DP was confirmed by ultrasonographic assessment. Antibiotherapy and intermittent positive airway pressure ventilation by a nasal mask resulted in significant improvement in the general condition of the patient. Respiratory problems were observed only on exertion. Spontaneous recovery of DP was considered and the patient was discharged 10 days after surgery with grade 1 dyspnea. However, after six months of follow-up, increased elevation of the left hemidiaphragm was noted on the chest X-ray with worsening respiratory discomfort even at rest. Thoracoscopic diaphragmatic plication was performed. After the operation, dyspnea disappeared, the chest X-ray showed the left hemidiaphragm in its normal position, and there was marked improvement in spirometric values.

Findings on electrocardiogram may hint that pulmonary embolism (PE) is present when interpreted in the proper context and lead to definitive imaging tests. However, it would be useful to know if electrocardiographic (ECG) abnormalities also occur in patients with pneumonia and whether these are similar to ECG changes with PE. The purpose of this investigation was to determine ECG findings in patients with pneumonia. We retrospectively evaluated 62 adults discharged with a diagnosis of pneumonia who had no previous cardiopulmonary disease and had electrocardiogram obtained during hospitalization. The most prevalent ECG abnormality, other than sinus tachycardia, was minor nonspecific ST-segment or T-wave changes occurring in 13 of 62 (21%). Right atrial enlargement occurred in 4 of 62 (6.5%). QRS abnormalities were observed in 24 of 62 (39%). Right-axis deviation and S(1)S(2)S(3) were the most prevalent QRS abnormalities, which occurred in 6 of 62 (9.7%). Complete right bundle branch block and S(1)Q(3)T(3) pattern occurred in 3 of 62 (4.8%). ECG abnormalities that were not present within 1 month previously or abnormalities that disappeared within 1 month included left-axis deviation, right-axis deviation, right atrial enlargement, right ventricular hypertrophy, S(1)S(2)S(3), S(1)Q(3)T(3), low-voltage QRS complexes, and nonspecific ST-segment or T-wave abnormalities. In conclusion, electrocardiogram in patients with pneumonia often shows QRS abnormalities or nonspecific ST-segment or T-wave changes. ECG findings are similar to ECG abnormalities in PE and electrocardiogram cannot assist in the differential diagnosis.

We report an 82-year-old female with pneumococcal pneumonia. Antimicrobial therapy was started in an early stage of the disease. On the 10th day of admission she developed peripheral pitting oedema with elevated jugular venous pressure and a drop in blood pressure. Her electrocardiogram showed sinus tachycardia and concave upward ST-segment elevation in almost all leads. A transthoracic two-dimensional echocardiogram revealed a large circumferential pericardial effusion, with diastolic collapse of the right atrium and a mitral inflow pattern that suggested cardiac tamponade. Emergency pericardiocentesis was performed, releasing 600 cc of thick green purulent material, followed by good haemodynamic recovery. The haemodynamic state, pneumonic infiltrate and inflammatory parameters responded gradually to antimicrobial therapy and the patient recovered and was discharged after six weeks. We conclude that even susceptible strains of Streptococcus pneumonia in a patient with no predisposing factors may still cause purulent pericarditis, even in the era of adequate antibiotic therapy.

We present the case of a 16-year-old boy with a family history of epilepsy who presented with acute respiratory failure, limb weakness, diabetes mellitus, sinus tachycardia, lactic acidosis, and pneumonia. He went on to develop cranial nerve palsy, myoclonus, generalized seizures, ataxia, recurrent pneumonia, and hypotension. Biochemical investigation revealed elevated lactate, pyruvate, and glucose levels. Cerebral magnetic resonance imaging (MRI) revealed bilateral, symmetric, high-intensity T2-weighted signals in the thalamus, brainstem, and gray matter of the spinal cord. Histochemical analyses revealed ragged red fibers (RRF) and decreased cytochrome oxidase activity. Blood and muscle-derived DNA demonstrated a high level (95% and 96%, respectively) of the m.8344A>G mutation, while almost all of his maternal relatives (n = 17, including his mother) carried the same point mutation. The point mutation level of his mother (who had short stature, high blood lactate levels, and epilepsy) was 77% (blood-derived DNA). Although this mutation has been identified in approximately 30 individuals with these disorders, to our knowledge, this is the first reported case of overlapping Leigh syndrome/myoclonic epilepsy with RRF in an adolescent patient, and the largest reported pedigree of mitochondrial DNA A8344G mutation.
