[A 22-year-old mother with severe pruritus and increasing jaundice two weeks after starting hormonal contraception]. / Eine 22-jährige Mutter mit starkem Juckreiz und zunehmendem Ikterus zwei Wochen nach Beginn der hormonalen Kontrazeption.

Intermittent cholestatic liver disease may indicate an inherited deficiency of bile salt transport proteins. Episodes of cholestasis may start during pregnancy or during use of oral contraceptives or other medication. We describe the case of a 22-year-old mother with increasing jaundice and severe pruritus two weeks after starting hormonal contraception. A few months before she was suffering from intrahepatic cholestasis of pregnancy (ICP). Liver biopsy showed bland cholestasis with canalicular bile plugs. Treatment with ursodeoxycholic acid was not effective. Finally, rifampicin induced a complete remission of the cholestasis. Genetic testing showed a heterozygous mutation in the ABCB11 gene encoding the bile salt export pump (BSEP). Rifampicin activates nuclear receptors and may induce alternative pathways for the excretion of bile salts in patients with ABCB11 deficiency.

[Prompt control of an imported carbapenem-resistant Acinetobacter baumanii outbreak in a French intensive care unit]. / Contrôle rapide d'une épidémie par une souche d'Acinetobacter baumanii résistant à l'imipénème importée de pays émergent dans un service de réanimation en France.

OBJECTIVE: to describe the management and control of a limited outbreak of carbapenem-resistant Acinetobacter baumanii (CRAB) outbreak in a French intensive care unit. METHODS: Careful review of the contact's and carrier's files and outbreak management procedures. RESULTS: An undiagnosed CRAB carrier was admitted to our intensive care unit after medical evacuation from Turkey. Despite preventive isolation and contact precautions, a secondary case was diagnosed 5 days after admission of the index case and resulted in the creation of a crisis unit. Prompt management included an epidemiologic investigation with contact screening and follow-up, environmental screening, and additional restrictive measures: isolation room, closure of adjacent rooms, patient cohorting with designated nurses, and reinforcement of contact precautions. CONCLUSIONS: restrictive management of CRAB outbreaks may allow prompt outbreak control and avoid prolonged room closures.

Surfactant abnormalities in idiopathic pulmonary fibrosis, hypersensitivity pneumonitis and sarcoidosis.

Bronchoalveolar lavage fluids (BALF) from patients with idiopathic pulmonary fibrosis (IPF; n=36), hypersensitivity pneumonitis (HP; n=32) and sarcoidosis (n=44) were investigated for their surfactant properties and compared to healthy control subjects (n=29). The phospholipid (PL) and protein concentration, the PL:protein ratio, PL subclasses, and the surfactant apoproteins (SP)A and SP-B were quantified in BALF. Large surfactant aggregates (LSA) were measured by means of ultracentrifugation and assayed for surface activity using the pulsating bubble surfactometer. As compared to controls, SP-A concentrations, LSA content and PL:protein ratios were significantly decreased in all groups, whereas PL and SP-B concentrations remained unchanged. Changes in the phospholipid profile, with reduced percentages of phosphatidylcholine (not significant) and phosphatidylglycerol and increased fractions of phosphatidylinositol and sphingomyelin (p<0.05), occurred more in IPF than in HP, and not in sarcoidosis. Surface activity was found to be severely impaired in IPF (minimum surface tension (gamma min) approximately 15-20 mN x m(-1)), but only modestly affected in HP and sarcoidosis (gamma min approximately 5 mN x m(-1)) compared to controls (gamma min approximately 0 mN x m(-1)). Reconstitution of pelleted surfactant material with soluble BALF proteins further increased gamma min values. In conclusion, moderate changes in biochemical and physical surfactant properties are encountered in hypersensitivity pneumonitis and sarcoidosis, but pronounced disturbances occur in idiopathic pulmonary fibrosis.

Familial psychiatric illness and obstetric complications in early-onset affective disorder. A case-control study.

Early-onset affective disorder is associated with obstetric complications and a high familial risk of psychiatric illness, in particular psychosis. In a matched case-control study, we investigated 47 adult in-patients with major depressive disorder or bipolar 1 disorder, who had earlier in life presented to a child psychiatry department. Cases were matched on sex, social class and ethnic group with 47 controls, who were admitted to hospital for affective disorders in adult life but had no psychiatric contact before the age of 21. We found that both psychiatric disorder in first-degree relatives and a history of obstetric complications were associated with early onset. Childhood symptoms did not predict the type of adult affective disorder.
