Identification of Cadmium Compounds in a Solution Using Graphene-Based Sensor Array.

Rapid detection of heavy metals in solution is necessary to ensure human health and environmental protection. Some heavy-metal compounds are present in solution as compounds instead of as ions owing to their low ionization. Therefore, the development of sensor devices for the detection of heavy-metal compounds is important.

Treatment of intractable diseased tissue in the maxillary sinus after endoscopic sinus surgery with high-pressure water jet and preservation of the periosteum.

Objective: To describe a new high-pressure water jet (HPWJ) treatment to remove intractable diseased mucosa persisting in the maxillary sinus several months after endoscopic sinus surgery (ESS) while preserving the periosteum.

Design: A retrospective review of HPWJ treatment in 45 consecutive patients with at least 12 months follow-up.

Setting: A private surgicenter in Japan.

Extended endoscopic frontal sinus surgery to interrupted nasofrontal communication caused by scarring of the anterior ethmoid: long-term results.

Objective: To examine the long-term results of extended endoscopic frontal sinus surgery, including removal of the floor of the frontal sinus (Draf type II procedure) and the median drainage operation (Draf type III procedure or modified Lothrop procedure), for obstructive frontal sinusitis caused by postoperative scar formation, with the emphasis on the long-term success of the median drainage procedure.

Design: Retrospective review of 22 consecutive cases of extended endonasal frontal sinus surgery in patients with obstructive frontal sinusitis caused by postoperative scarring.

Setting: The procedures were performed at a private surgicenter in Japan.

[A case of lymphoma which developed bone, liver, and skin lesions two years after the diagnosis of lymphoid interstitial pneumonia].

We reported a case of lymphoid interstitial pneumonia (LIP) in 1985. The patient, a 37-year-old housewife, had suffered from cough and dyspnea. Her chest roentgenograms revealed bilateral diffuse micronodular shadows.
