Atypical expiratory flow volume curve in an asthmatic patient with vocal cord dysfunction.

BACKGROUND: Vocal cord dysfunction can coexist with or masquerade as asthma. Vocal cord dysfunction, when coexistent with asthma, contributes substantially to the refractory nature of the respiratory problem. OBJECTIVE: To report a case of an asthmatic patient with vocal cord dysfunction and a previously unreported unique expiratory flow volume curve. RESULTS: A 16-year-old female, known to have asthma, developed increased frequency of her asthma exacerbations. Spirometry, during symptoms, showed an extrathoracic airway obstruction with a reproducible unique abrupt drop and rise in the expiratory flow volume loop. Laryngoscopy showed adduction of the vocal cords during inspiration and expiration. CONCLUSIONS: We report a unique expiratory flow volume curve in an asthmatic with vocal cord dysfunction that resolved with panting maneuvers. Speech and psychological counseling helped prevent future attacks.

Wheezing and vocal cord dysfunction mimicking asthma.

Vocal cord dysfunction (VCD) is a respiratory disorder characterized by paradoxical closure of the vocal cords during the respiratory cycle leading to obstructive airway symptoms. The presenting symptoms vary from stridor to wheezing. VCD may coexist with asthma or masquerade as asthma. Misdiagnosis of VCD as asthma leads to inappropriate use of systemic steroids with its adverse effects, frequent emergency department visits, hospitalization, and, rarely, intubation and tracheostomy. Attenuation of the inspiratory flow volume loop on spirometry is suggestive of VCD. Laryngoscopic demonstration of the paradoxical vocal cord movements during an acute attack is the gold standard for the diagnosis of VCD. Patient education, speech therapy, and psychologic counseling are the therapeutic tools for treatment.

Typhoid hepatitis in children.

Liver involvement is commonly observed in patients with typhoid fever. However, a hepatitis-like picture with fever and jaundice is unusual and infrequently reported in the paediatric literature. Our aim was to characterize the clinical picture, biochemical features, and prognosis of typhoid hepatitis. One hundred cases of typhoid fever (age 0 to 12 years), proven by positive blood cultures to Salmonella typhi, were studied with special reference to hepatic dysfunction. Of these, eight patients were found to have hepatitis during the course of their illness. All had high fever, tender hepatomegaly, elevated serum bilirubin (in the range of 2.5-5.8 mg/dl), and elevated serum alanine transaminase levels (in the range 100-620 IU/l). All the eight patients showed complete clinical and biochemical recovery in response to appropriate antibiotics. The clinical picture of typhoid hepatitis frequently mimics acute viral hepatitis. In tropical areas, the differential diagnosis of a child presenting with fever and jaundice should include typhoid hepatitis.
