Real-time PCR method for identification of Asian populations in forensic casework.

The priorities for mass disaster victim identification are rapid investigation turn-around time and low cost. We describe a DNA typing procedure to selectively identify members of Asian populations by a real-time PCR method using polymorphisms of the alpha2 chain of the type I collagen gene (COL1A2) and mitochondrial DNA (mtDNA). Among the 50 members of the Asian population included in the present study, 37 harbored a deleted allele in intron 33 of COL1A2 (26822-26823del) or the 10400C>T substitution mutation in mtDNA to give a probability of 0.

Genetic polymorphism in collagen type 1 alpha 2 intron 33 can be used for the initial screening of East Asians quickly and easily by a heteroduplex analysis.

To save time and simplify the matching genetic information of bereaved family with the collected samples for identification of individuals in a mass-scale disaster and terrorism using molecular biological methods, we propose a method to initially screen samples according to different populations. We found a unique deletion (26822-3) in an allele that 62.0% of East Asian individuals had in intron 33 of type I collagen alpha 2 (COL1A2), while most Europeans and Africans did not have it.

[Medico-legal autopsy case of an infant suffering anaphylactic shock during dental treatment. Potential hazards in the use of a rubber-dam-sheet for infants].

We report a medico-legal autopsy of a 4-year-old girl without any history of allergies, who died following anaphylactic shock due to local anesthesia with lidocaine during dental treatment. The shock symptoms were overlooked due to a rubber-dam-sheet covering her face. The autopsy revealed laryngeal edema, secretory fluid filling the trachea, severe pulmonary congestion and edema.

[Tuberculous lymphadenitis: a clinical study of 23 cases].

Introduction: Tuberculous lymphadenitis is a relatively rare disease in adults. In the absence of pulmonary tuberculosis, tuberculous lymphadenitis is very difficult to differentiate from other diseases. We described our experiences of patients with tuberculous lymphadenitis.

[A case of miliary tuberculosis complicated with a tuberculous aneurysm of the aorta].

A 68-year-old man was admitted because of fever and weight loss. A chest high-resolution computed tomography (HRCT) scan revealed diffuse micronodular shadows, and an abdominal CT scan showed an aneurysm spreading from the root of the renal artery to the iliac bifurcation. His fever subsided without treatment and his general condition was good.

[An elderly patient with advanced non-small-cell lung cancer that responded remarkably to combination chemotherapy of vinorelbine and gemcitabine].

A 73-year-old man was admitted to our hospital because of hemoptysis in November 1999. A chest CT revealed a mass shadow in the right upper lobe and enlarged hilar and pretracheal lymph nodes. Bone scintigraphy showed a bone metastasis in right middle rib.
