Cervical lymphadenopathy in young children: case report of nontuberculous mycobacterial infection.

A four-year-old male presented with right-sided facial swelling near the angle of the mandible. Despite the presence of multiple dental carious lesions, the cervical lymphadenopathy did not appear to be of dental origin. Otolaryngology referral with subsequent excision of the affected lymph nodes confirmed the cervical lymphadenopathy to be due to a Mycobacterium avium intracellulare infection.

Assessment of a novel alternative to conventional formocresol-zinc oxide eugenol pulpotomy for the treatment of pulpally involved human primary teeth: diode laser-mineral trioxide aggregate pulpotomy.

Objective: The purpose of this study was to investigate whether a diode laser pulpotomy with mineral trioxide aggregate (MTA) sealing could be an acceptable alternative to the conventional formocresol pulpotomy and zinc oxide eugenol (ZOE) sealing in human primary teeth.

Methods: A randomized, single-blind, split-mouth study was used with a sample of 16 children aged from 3 to 8 years (mean age=5.10 years).

Indium light source for curing composite resins.

There is an existing problem of cumulative hazardous effect of violet and near ultra-violet light which is produced by standard polymerisation units. Another restrict is shallow depth of cure, particularly of darker composite shades in premolar and molar region. Searching for better light source we used indium resonance lines from several indium high pressure lamps and tested curing effect on three different composite resins.

Zinc and sodium high pressure lamps for curing composite resins.

Polymerisation characteristics of conventional units for curing composite resins are insufficient considering handling feasibilities particularly in the premolar and molar region. There is also hazardous ocular effect of near ultra-violet part of visible spectra. Sodium high pressure lamp technology has been applied to develop a new high pressure zinc lamp, which is for the first time used for curing composite materials.

[Use of the EEA stapler in surgery of the rectum and rectosigmoid junction].

The application of mechanic sewing apparatus has obtained significant position in surgery of gastrointestinal tract. The EEA stapler (ILS Proximate) is improved, suitable and useful instrument for the performance of anastomosis after resection, and technically is equivalent to the normal suture techniques. It is especially convenient for the creation of low rectal anastomoses, thus definitive anus preter can be avoided.

[Incarcerated hernia in the left groin associated with acute gangrenous appendicitis].

Discussed is a patient with both a mechanical and paralytic ileus as a result of a gangrenous appendicitis with perforation and a circumscribed peritoneum and incarceration of an inguinal hernia on the opposite side. The patient's heart too was suffering a disease. The postoperative course was difficult.
