We report a case of postpartum choriocarcinoma from a 23-year old primiparous woman which was preceded by fetal anemia and intrauterine fetal death at 37 weeks' gestation. It has not been previously described in Korean literatures. The placenta, weighing 550 gm, contained multiple intervillous thrombi with laminated fibrin residue and pale cut curface. Histologic evidence of choriocarcinoma was not found in the placenta or in any fetal organs at autopsy, but large number of nucleated red blood cells and immature hemopoietic cells in the fetal capillaries of the placenta suggested the presence of fetal anemia. It was assumed that feto-maternal transfusion might had played a major role of fetal anemia and death.

We described a giant chroioangioma of the placenta that caused premature rupture of membranes at 31 weeks of gestation in a 31-year-old primiparous woman and a subsequent neonatal death of the baby. The placental mass, weighing 820 gm and measuring 21.5x15x4.5 cm, was easily shelled out from a edematous 1280 gm-placenta. The mass had a thin fibrous capsule and a solid fibromatous appearance. The infant, weighed 2175 gm, appeared edematous oon the whole body and had Apgar scores of 4 and 5 at 1 and 5 minutes respectively. The baby expired 4 days after birth due to high output cardiac failure and respiratory failure. Postmortem examination revealed markedly dilatated umbilical vein, inferior vena cava and right atrium with patent froamen ovale, congestive hepatosplenomegaly, pulmonary hemorrhages, and meconium aspiration pneumonia. Microscopically, the mass revealed a variety of histologic patterns, reflecting entire spectrums of villous vasculogenesis from loose myxomatous connective tissue and undifferentiated hemangioblastic cell nests to well-developed capillaries with hematopoietic cells in the lumen.

Obstructive sleep apnea (OSA) is a common disorder characterized by recurrent cessation of breathing due to complete or partial upper airway occlusion during sleep. The incompetent tone of palatal, pharngeal, and glossal muscles which fail to maintain airway patency during sleep causes narrowing of the airway dimension and increased resistance of breathing. The identification of the sites of upper airway obstruction in patients with OSA is important in understanding the pathogenesis and deciding the treatment modality of snoring and/or OSA. Various upper airway imaging modalities have been used to assess upper airway size and precise localization of the sites of upper airway obstruction during sleep. Dynamic imaging modalities enabled assessment of dimensional changes in the upper airway during respiration and sleep. This article focused on reviews of various upper airway imaging modalities, especially dynamic upper airway imaging studies providing important information on the pathogenesis of OSA.

This paper illustrate residual hearing and socio-medical background on the hearing impaired children, 207 coming to Deaf School, attached to Hankuk Social Work College, Tague, Korea. The survey was performed through interview with their parents and testing by diagnostic audiometer (TRIO, AS 105 type) at soundproof room from March 10, to November 28, 1973. The results obtained were as follows. 1) The attendance rate of the compulsory primary school was markedly lower tendency in female than according to directly proprotinoal to prevalence rate of deafness amont them, If was showed the deeper gap in the more superior school (middle and high school). 2) Who entered at the suitable age to each school (six years old to primary school, 12 years to middle and 15 years to high) was 11.3%. And who were enrolled in school age to each school (6-11) years for primary. 12-14 years for middle and 15-17 years for high) was 45.9% (43.7% in male, 50.0% in female). 3)As causative disease, congenital case, were 23.6% include of 13.5% of heredity and 10.1% of troubles during pregnancy ; the total acquired cases were 47.9%, it was classified as 11.6% of convulsion from any other diseases, 7.7% of measles, 7.7% of other febrile diseases, 3.4% of drug (the most of streptomycin) intoxication, 2.4% of meningitls, 1.5% of epidemic encephalitis and 31.3% of other diseases ; and unknown cases were 28.5%. 4)31.4% of who included congenital cases lost their hearing within six months old, 11.6% in 6-11 months. 9.7% n 1-2 years old and 14.0% in 2-3years old. Consequently we obtained that the most cases 90.0% were lost their hearing within 3 years after birth.

We are report on three cases of typical clinical characterstics and treatment response in neuroleptic maligant syndrome(NMS), and reviewed the literatures of NMS. NMS was first recognized as a life-threatening complication of dopamine receptor antagonists, and defined as a catatonic-like states associated with fever, obtundation, muscle rigidity, and unstable vital sign in patients taking neuroleptic agents. Concepts of NMS have changed because medications other than classic neuroleptic drugs have been implicated as triggering agents and syndromes identical to NMS have been observed in other conditions. The important neurochemical features are probably functional dopamine deficiency and ensuing hyperactivity of excitatory amino and neurotransmission in the basal ganglia and hypothalamus. Recognition of NMS and early discontinuation of neuroleptics are the most important step in its management. Supportive care includes management of hyperthermia and fluid replacement. Contraversial therapeutic measures include the application of dopamine receptor agonists, excitatory amino acid antagosists, or dantrolene. Psychiatric patients with a history on NMS and psychotic relapse necessitating antipsycotics do not commonly redevelop NMS.
