Histiocytic necrotizing lymphadenitis that causes unusual lymphadenopathy is a newly recognized disease of unknown etiology and may be mistaken for other conditions such as malignant lymphoma and tuberculosis, in which specific treatment will be required. Local lymph node enlargement especially in neck is the only characteristic feature, sometimes accompanied by pain, tenderness, fever and chill like a cold, nausea, vomiting. Laboratory investigations are usually noncontributory with an occasional case showing leukopenia or an elevated erythrocyte sedimentation rate. For further understanding of this disease and helping make diagnosis, clinical features were reviewed in 15 patients (29 lymph node enlargement), who were diagnosed as histiocytic necrotizing lymphadenitis on clinical evaluation (9 patients) or excisional biopsy (6 patients). The results are as follows; Disease was more common in female(1:2) and young patient. It involved left sided neck nodes frequently (67%) and the most common site was suboccipit-al triangle (62%). 47% of patient showed multiple enlargement of lymph nodes and the size of nodes were varied from 8 to 23 mm (mean: 12.4 mm). Most nodes were movable and showed oval in shape. Fever (47%), pain (33%), tenderness (53%), recent history of upper respiratory infection (33%), leukopenia (47%) and increased erythrocyte sedimentation rate (67%) were showed in many cases. Ultrasonogrphic and CT scan showed well defined oval to round lymph nodes enlargement with inhomogenous enhancement. All affected nodes are resolved spontaneously within 3-10 weeks (mean 5.1 weeks) without specific treatment. After reviewing all of above results, it is concluded that histiocytic necrotizing lymphadenitis is self-limiting disease without characteristic clinical features, but some factors like fever, pain, tendrness, leukopenia and increased erythrocyte sedimentation rate with cervical lymphadenopathy in young female patient are thought to be very helpful in diagnosis and in these circumstances, lymph node biopsy must be delayed for 2-3 months.

Background: Spontaneous pneumopericardium is a very rare condition. Spontaneous pneumothorax and pneumomediastinum have been reported to be associated with an idiopathic pulmonary fibrosis (IPF). However, spontaneous pneumopericardium has not yet been reported in association with IPF. Here we report a case of spontaneous pneumomediastinum and pneumopericardium in a patient with acute exacerbation of IPF with a review of the relevant literature.

In order to assess the efficiency of Percoll gradient centrifugation(PGC) as a method of sperm selection, we have examined morphological characteristics of spermatozoa from 40 teratozoospermic patients attending the Infertility Clinic of Inchon Gil Gerneral Hospital. Patients were divided into three groups according to percentage normal morphology in the fresh sample : group A(n=5), < 5% normal morphology : group B(n=21), 5~14% normal morphology : and group C(n=14), > 14% normal morphology. Morphology slides were perpared using Diff-Quik staining techniques and evaulated by Kruger strict criteria, under oil immersion at a magnification of X 1000, specific defects, head, neck and tail were assesed individualy. The results were as follows. 1. Following PGC, sperm samples with enhanced morphology were recovered for all groups. 2. For group A, PGC did not select a sample with significantly improved morphological characteristics. 3. Usually, sperm defects affected by PGC was head and neck. No significant difference was found for tail abnormality. In conclusion, Percoll gradient centrifugation is an efficient sperm preparation technique when the semen sample exhibits teratozoospermia, especially head or neck abnormality. However, in sample with < 5% normal form or tail abnormality, There is not significant improvement following PGC.

BACKGROUND: IL-8 is a potent chemotactic cytokine that plays an important role in the host defense mechanism against M. tuberculosis by recruiting inflammatory cells to the site of the infection. Lung epithelial cells, as well as alveolar macrophages are known to preduce IL-8 in response to M. tuberculosis. IL-8 gene expression is mainly regulated on the level of transcription by NF-κB. This study investigated whether or not A549 cells produce IL-8 in NF-κB dependent mechanism in response to macrophages phagocytosing M. tubersulosis. METHODS: Peripheral blood monocytes that were obtained from healthy donors were cultured for 24 h with M. tuberculosis and a conditioned medium(CoMTB) was obtained. As a negative control, the conditioned medium without M. tuberculosis (CoMCont) was used. A549 cells were stimulated with M. tuberculosis, CoMCont and CoMTB and the IL-8 concentration in the culture media was measured by ELISA. The CoMTB induced IL-8 mRNA expression in the A549 cells was evaluated using RT-PCR, and CoMTB induced IκBα degradation was measured using western blot analysis. CoMTB induced nuclear translocation and DNA binding of NF-κB was also examined using an electrophoretic mobility shift assay(EMSA), and the CoMTB induced NF-κB dependent IL-8 transcriptional activity was measured using a luciferase reporter gene assay. RESULTS: CoMTB induced IL-8 production by A549 cells(46.8±4.8 ng/ml) was higher than with direct stimulation with M. tuberculosis (6.8±2.9 ng/ml). CoMTB induced IL-8 mRNA expression increased after 2 h of stimulation and was sustained for 24 h. IκBα was degraded after 10 min of CoMTB stimulation and reappeared by 60 min. CoMTB stimulated the nuclear translocation and DNA binding of NF-κB. The CoMTB induced NF-κB dependent IL-8 transcriptional activity(13.6±4.3 times control) was higher than either CoMCont(2.0±0.6 times control) or M. tuberculosis (1.4±0.6 times control). CONCLUSION: A conditioned medium of peripheral blood monocytes phagocytosing M. tuberculosis stimulates NF-κB dependent IL-8 production by the lung epithelial cells.

Vertigo mimicking labyrinthine lesions may have resulted from ischemic insult to the inner ear or the vestibular nerve and nucleus in the AICA infarction syndrome. A 56-year-old female was admitted to the emergency room with vertigo and hearing loss in right ear. On neurological examination, she had left beating jerky torsional and horizontal nystagmus with falling and past pointing to right side. Brain magnetic resonance images showed high signal intensity in anterolateral portion of inferior pons on T2- weighted images. Severe right facial palsy of peripheral type developed 24 hours after admission. Audiometry and electronystagmography documented absent auditory and vestibular function on the affected side. We argue that vertigo of the acute infarction in AICA territory can be involved the eight and seventh nerve root entry zoon and mimic labyrinthine lesions

OBJECTIVES: The aims of this study were to know the prevalence of cognitive disorders in patients with thyroid cancer, and identify related variables to them. METHODS: Subjects were consisted of fourty-two patients with thyroid cancer, who were admitted for radioiodine ablative therapy at 6-12 months after total thyroidectomy. The data were obtained from interviews about history and assessments of depression and cognitive function(Korean Version of the Montreal Cognitive Assessment, MoCA-K). RESULTS: 1) Among subjects, those with below 22 of total score of the MoCA-K were twenty-one(50.0%). 2) Upon age, education, Pre-radioiodine therapy thyroid stimulating hormone(TSH), there were statistically significant difference between subgroup with above 23 of the total MoCA-K score and those below 22. 3) The total scores of the MoCA-K in subjects had significant correlation with age, education, comorbidity, Pre-radioiodine therapy TSH, total score of the HDRS-17. CONCLUSIONS: Cognitive disorders were more prevalent among patients with thyroid cancer before radioiodine therapy. Therefore, further study should be needed to clarify the mechanism for the cognitive disorders in thyroid cancer. Furthermore, physicians should pay attention to the cognitive function and prepare preventative measures for cognitive disorder during management of thyroid cancer.

Eccrine nevus is an unusual entity with various clinical manifestations. Histologically the eccrine apparatus appears simply increased in number and/or size, but structurally normal. We present a case of eccrine nevus on the dorsum of the left 3rd and 4th fingers in a 20 year-old female. The lesions were 3 × 2cm sized, well demarcated, smooth surfaced, brownish plaques with mild hyperhidrosis. Histological examination revealed hyperkeratosis in the stratum corneum and hyperpigmentation of basal layer, and an increased number of eccrine sweat glands and many eccrine coils in the dermis was seen.
