[Toxic shock-like syndrome of the neck, a case report].

Streptococcal toxic shock-like syndrome (TSLS) is known to progress rapidly into septic shock and have a high mortality of 40%. We report a rare case of neck infectious disease caused by Group A hemolytic streptococcus pyogenes. A 65-year-old man, hospitalized for eyelid swelling and dyspnea suffered shock, dyspnea, and pressure reduction on the day he was hospitalized and died of multiple organ failure 18 days later. Despite treatment with antibiotics, tracheostomy, immunoglobulin, etc. We suspected that he had been infected via a laceration of the external auditory meatus. Accurate diagnosis followed by prompt, radical treatment is essential if TSLS is to be treated successfully.

Narrowband generation of ultrafast acoustic and thermal transients in thin films for enhanced detectability.

A technique for the narrowband generation of ultrafast acoustic and thermal transients in thin films is demonstrated; this technique allows for enhanced detectability of these transients. The approach pursued uses a reduced-bandwidth, optical pulse train for excitation that is constructed from a series of time-delayed pulses derived from a single-laser pulse. The underlying physical limitations of this approach are considered in order to assess conditions under which successful bandwidth reduction can be realized. Results in an aluminum thin film on a tungsten-carbide substrate show successful generation and detection of a narrowband acoustic signal centered at 32.34 GHz.

A case of hypogonadotropic hypogonadism caused by opioid treatment for nonmalignant chronic pain.

We report a case of 42-year-old male patient with hypogonadotropic hypogonadism. He suffered from general fatigue and erectile dysfunction after the treatment with transdermal fentanyl for chronic pain by traffic injury. Endocrine examinations and hormone stimulating tests showed that he had hypogonadotropic hypogonadism. Brain magnetic resonance imaging (MRI) showed no abnormal findings, and he had no past history of accounting for acquired hypogonadotropic hypogonadism. Therefore, his hypogonadism was diagnosed to be caused by opioid treatment. Although opioid-induced endocrine dysfunctions are not widely recognized, this case suggests that we should consider the possibility of endocrine dysfunctions in patients with opioid treatment.
