A 38-Year-Old Man With a 2-Month History of Fever, Cough, Palpitations, and Weight Loss.

CASE PRESENTATION: A 38-year-old man of Indian origin, who migrated to Greece 13 years prior to presentation, was admitted to our hospital with a 2-month history of nonprogressive, intermittent (mostly evening), low-grade (up to 38.5°C) fever, accompanied by night sweats, dry cough, mild dyspnea on exertion (modified Medical Research Council Dyspnea Scale grade 1), anorexia, fatigue, and weight loss of 10 kg. He also experienced continuous palpitations, which were regular, not associated with chest pain or dizziness, and aggravated on exertion. He had not taken any medication for his condition, except for antipyretic agents, nor had he sought medical advice. He was a nonsmoker, had a history of past alcohol dependence, and had been hospitalized twice for acute pancreatitis due to hypertriglyceridemia. He had also been diagnosed with diabetes mellitus, presumably poorly controlled because he mentioned not taking any medication or having regular follow-up.

Unilateral pulmonary hypoplasia in an adult patient.

Pulmonary hypoplasia (PH) is a developmental anomaly of the lung parenchyma, characterized by a decrease in the number and size of airways, alveoli and vessels. We present a case of a 31-year-old patient with a history of chronic productive cough and frequent respiratory infections, who was referred for investigation of abnormal chest x-ray. The combination of chest computed tomography (CT) and bronchoscopy set the diagnosis of left pulmonary hypoplasia and the patient was treated surgically with a left pneumonectomy. PH is usually diagnosed immediately after birth, causing severe respiratory failure with high mortality. The less severe, unilateral forms can possibly survive by causing compensatory hyperinflation of the other lung and remain undiagnosed until adulthood, presenting either asymptomatic or with symptoms of chronic bronchitis and recurrent respiratory infections. Chest CT is considered the imaging technique of choice for the diagnosis and for the differential diagnosis from other congenital or acquired conditions. The treatment is usually conservative, although surgical resection is indicated in cases of severe cystic changes and intense symptomatology.

A prospective study on bacterial and atypical etiology of acute exacerbation in chronic obstructive pulmonary disease.

AIM: The bacterial and atypical etiology of acute exacerbations of chronic obstructive pulmonary disease was investigated and the diagnostic techniques used were compared among 92 hospitalized patients. MATERIALS & METHODS: Sputum specimens were investigated using culture and PCR, serological status evaluation was performed and the inflammatory profile was associated with the microbiological results. RESULTS & CONCLUSION: The majority of the patients (65.2%) had very severe airway obstruction. The most common bacteria were Haemophilus influenzae and Pseudomonas aeruginosa (23.9 and 14.1%, respectively). Acinetobacter baumannii- and P. aeruginosa-positive cultures were associated with prolonged hospitalization and severe airway obstruction (p = 0.03 and 0.031, respectively). Chlamydia pneumoniae or Mycoplasma pneumoniae infection was diagnosed in four and two patients, respectively. Discrepant results were detected between PCR and serology, especially regarding C. pneumoniae.
