This is the first report of an autopsy case of acetyl fentanyl delivered by insufflation, rather than intravenous administration.

Two Cases of the Laryngeal Cystic Lesions.

We experienced two rare cases with laryngeal cystic lesions (laryngocele and laryngeal cyst). In the first case, the laryngocele case was removed by laryngomicrosurgery using an oral approach under general anesthesia. In the second case, the magnetic resonance imaging demonstrated a dumbbell-type cyst with mucus widely extending from the laryngeal lumen to the neck through the thyroid cartilage.

[Virus-associated hemophagocytic syndrome (VAHS) as an initial manifestation in HIV infection].

A 21-year-old man admitted for idiopathic fever and sore throat was diagnosed with virus-associated hemophagocytic syndrome (VAHS) when bone marrow aspirate showed hemophagocytosis. ELISA for HIV antibodies was negative, although HIV RNA was positive. VAHS is extremely rare as an initial manifestation in HIV infection, being reported, to our knowledge, in only 4 subjects in Japan.
