Tracheopathia osteoplastica is a rare, benign pathologic condition chahacterized the occurrence of numerous cartilage and bony nodules within the tissue of mucosa. We report a case of tracheopathia osteoplastica that involved both larynx and trachea. The patient was 73 years old male and had hoarseness. The neck CT showed thickened and irregular wall of the trachea extending to the level of the carina with multiple calcified nodules and plaques of bony density projecting into the lumen.

OBJECTIVES: This study was conducted to investigate that the chronic noise exposure is associated with decreased serum magnesium concentrations and evaluate whether decreased serum magnesium is associated with noise induced hearing loss. METHODS: One hundred seventy-eight male workers exposed to noise were selected and classified three groups by the degree of hearing loss. Hearing threshold levels were less than 30 dB at 1,000 Hz or less than 40 dB at 4,000 Hz in group I, more than 30 dB at 1,000 Hz or more than 40 dB at 4,000 Hz and 15 dB and less of pure tone average(PTA: (500 Hz+1,000 Hz+2,000 Hz)/3) in group II, more than 30 dB at 1,000 Hz or more than 40 dB at 4, 000 Hz and over 15 dB of PTA in group III. RESULTS: Serum magnesium concentrations were 2. 42+/-0. 26 nc/dt in group I, 2. 35+/-0.23 mg(dl in group II, 2.26+/-0.24 ne/dl in group III, respectively and significantly different between group I and group III (p<0. 01). It was negatively correlated with duration of the noise exposure as correlation coefficient(r) of -0.194 (p<0.05). Analysis of the multiple regression on hearing threshold levels showed that serum magnesium, diastolic blood pressure, duration of the noise exposure were statistically significant at 4,000 Hz(p<0.05). While only age was statistically significant at 1,000 Hz(p<0.05). CONCLUSIONS: These results suggest that chronic noise exposure may induces decrease in serum magnesium concentrations and that its decreased concentration is related with noise induced hearing loss.

First branchial cleft anomalies constitute less than one percent of all branchial arch anomalies. First branchial clefi anomalies are classified into 2 digerent types with different embryologic, anatomical and histologic features by Work (1972)1. Among 2 types, type II anomaly is less common than type I and there has been no report of type II anomaly in the Korean literatures. We experienced a 5-year-old female who had a inflammed cystic mass over neck which was extended into parotid area After elevation of parotidectomy skin incision and superficial parotid gland, the cystic mass was observed to be extended upward into the parotid gland, medial to the facial nerve and ended at the external auditory canal. Microscopic examination shows that cyst wall is lined with squamous epithelium and contains some mesodermal tissue such as pilosebaceous gland and muscle. In conclusion, we can present this case as the first branchial cleft anomaly type II.

BACKGROUND: Bone marrow transplantation is increasingly common as a therapeutic modality. Large volume of bone marrow has been aspirated under general anesthesia and can cause hemodynamic instability and complications. The purpose of this study is to review the cases of bone marrow harvesting in healthy donors and to find the proper anesthetic management for this procedure. METHODS: We retrospectively analyzed the medical records of 479 cases of bone marrow harvesting in healthy donor performed in Catholic University of Korea, St. Mary's hospital. RESULTS: Mean harvest volume was 1097.2 120.6 ml and duration of aspiration was 53.8 22.6 minutes. Aspirated harvesting volume was mainly replaced by blood products and crystalloid solutions. 55.7% of donors received homologous blood products and 74.5% of donors received autologous blood during the perioperative period. Mean hemoglobin concentration before harvesting was 12.3 1.8 gm/dL and there was no significant changes in hemoglobin concentrations after harvesting. The incidence of hypotension and tachycardia was 22.3 and 20.5%, respectively with higher incidence in the female group (p<0.05). The incidence of febrile reaction after harvesting was 15.5%. Average duration of admission for harvesting was 3.5 0.9 days and there were no life-threatening complications. CONCLUSION: We conclude that 479 cases of bone marrow harvesting were performed safely but we should consider to reduce the volume of homologous transfusion in healthy donors.

To clarify neuronal connection of the medial rectus muscle at brain stem, Bartha strain of the psecudorabies virus(PRV-Ba) and cholera toxin-horeserdish peroxidase(CT-HRP) was injected into medial rectus muscle of the rat. About 84 hours after PRV or CT-HRP injection, the brain was removed and processed immunohistochemical stain for PRV-Ba and neurohistochemical stain for CT-HRP using tetramethyl benzidine. The CT-HRP positive reaction was only present in ipsilateral oculomotor nucleus, contralateral abducence nucleus and bilaterally in rostral interstitial nucleus of medial longitudinal fasciculus, olivary pretectal nucleus, medial and superior vestibular nucleus, nucleus prepositus hypoglossi, prerubral field, nucleus Darkschewitsch, lateral substantia nigra, terminal nucleus of accessory nucleus, dorsal raphenucleus, locus ceruleus and pontime reticular formation. This study confirmed that both oculomotor nucleus and abducence nucleus were connected with each other through the medial longitudinal fasciculus, and neuronal connection of the medial rectus muscle in the rat brain stem.

Livedo vasculitis or vasculitis of atrophie blanche is a clinical entity which can be distinguished from cutaneous vasculitis by distinctive pathology and immunopathologic study. A 18-year-old female with erythematous, telangiectatic, purpuric or hyperpigmented patches, intermingled with white atrophic ivory patches on her legs of 3 years duration was seen in June 3, 1982. The histologic examination of an atrophic patch showed proliferation and occlusion of blood vessels in the upper dermis with patchy atrophy of the epidermis. The immunopatbologic features of an atrophic patch revealed deposits of IgM, Ca and fibrin as a definitive immunofluorescence vessel pattern. This suggests that the livedo va.sculitis or vasculitis of atrophie blanche may he considered one of the immune vasculitides. This patient had received aspirin and persantine for 4 months, and moderate therapeutic effects could be noticed.
