Trichorhinophalangeal syndiome, a rare genetic disease, is characterzed by the triad of slow growing, brittle hair with early loss, a pear-shaped nose with bulbous tip and long philtrum, and coneshaped phalangeal epiphyses wiith resultant shortening and. deformity of hands and feet. A 24-year-old female visited our department for the evaluation of lalopecia. She had had sparse, thin, and brittle hair since birth. She also complained of short fingers ar d a pear-shaped nose with bulbous tip. The X-ray findings of her hands and feet showed cone-shaped epiphyses with shortening of the phalangeal bones. There was no family history of hair, nasal, or palnkoplantar phalangeal abnormality. Chromosomal study did not reveel any abnormal finding. Shortened phalangeal bones of her index and middle fingers were slightly improved by lengthening procedure with iIlizarov apparatus.

Purpose: Some patients who have undergone surgery due to lumbar disc herniation still complain of leg pain and other abnormal sensations. Therefore, the study examined the effects of the neurodynamics on pain and other abnormal nerve sensations in post-operated patients with lumbar disc herniation. Methods: The participants of this study comprised 20 adults (10 males and 10 females) who were diagnosed with lumbar disc herniation. The subjects were classified into two groups of 10 patients each in the lower extremity neurodynamics (LEN) and lumbar stabilization exercise (LSE) groups. Each intervention was applied twice a day for one week and was composed of two different exercise patterns; one was applied by a therapist, and the other was performed by the patients themselves. The data were analyzed using assessment methods of Digital Infrared Thermal Imaging (DITI), Toronto clinical neuropathy scoring system (TCNSS), Sympathetic Skin Response (SSR) test, and Oswestry Disability Index (ODI) scale. Results: Significant differences in TCNSS, DITI, ODI scale were observed between the LEN and LSE group (p<0.01). On the other hand, there was no significant difference in the SSR test between pre and post-treatment (p>0.05). Conclusion The results indicated that neurodynamics treatment is effective in pain reduction and abnormal sensations, such as leg muscle cramps, in post-operated patients with lumbar disc herniation.

BACKGROUND: In diagnosis or monitor of the airway obstruction in bronchial asthma, the measurement of FEV1 in the standard method because of its reproducibility and accuracy. But the measurement of peak expiratory flow(PEF) by peak flow meter is much simpler and easier than that of FEV1 especially in children. Yet there have been still no data of the predicted normal values of PEF measured by peak flow meter in Korean children. This study was conducted to provide equations to predict the normal value of PEF and correlation between PEF and FEV1 in healthy children. METHOD: PEF was measured by MiniWright peak flow meter, and the forced expiratory volume and the maximum expiratory flow volume curves were measured by Microspiro HI 501(Chest Co.) in 346 healthy children (age:5-16 years, 194 boys and 152 girls) without any respiratory symptoms during 2 weeks before the study. The regression equations for various ventilatory parameters according to age and/or height, and the regression equations of FEV1 by PEF were derived. RESULTS: 1. The regression equation for PEF(L/min) was:12.6×age(year)+3.4×height(cm)-263(R2=0.85) in boys, and 6×age(year)+3.9×height(cm)-293(R2=0.82) in girls. 2. The value of FEFmax(L/sec) derived from the maximum expiratory flow volume curves was multiplied by 60 to compare with PEF(L/min), and PEF was faster by 125 L/min in boys and 118 L/min in girls, respectively. 3. The regression equation for FEV1(ml) by PEF(L/min) was:7×PEF-550(R2=0.82) in boys, and 5.8×PEF-146(R2=0.81) in girls, respectively. CONCLUSION: This study provides regression equations predicting the normal values of PEF by age and/or height in children. And the equations for FEV1, a gold standard of ventilatory function, was predicted by PEF. So, in taking care of children with airway obstruction, PEF measured by the peak flow meter can provide useful information.

Intraocular lens power was calculated from data of axial length, corneal curvature, and anterior chamber depth in 112 eyes which underwent IOL implant surgery. Postoperative refractions of 112 eyes were analyzed into three groups such as the group of which constant A is 116.2, the group of which constant A is 116.8, and TI-59 system group. The results were as follows; 1. The A constant derived from retrograde analysis in our 112 cases was 116.2. In the cases of the constant A 116.2, error of predicted required spectacle lens power was -0.16D +/- 0.89 in relative average, 0.67D +/- 0.57 in absolute average. Using the standard formula described by Hoffer, the accuracy of IOL power calculation by the constant 116.2 was 76.1% +/- 1.0D / 97.4% +/- 2.0D / +2.42 to -2.11D. 2. The specific constant A of intraocular lenses inserted in our hospital was 116.8. In the cases of the constant A 116.8, error of predicted required spectacle lens power was -0.39D +/- 0.88 in relative average, 0.75D +/- 0.60 in absolute average. Using the standard formula described by Hoffer, the accuracy of IOL power calculated by the constant A 116.8 was 72% +/- 1.0D / 96% +/- 2.0D / +2.34 to -2,50D. 3. In TI-59 system of IOL power calculation, error of predicted required spectacle lens power was -0.12D +/- 1.0D in relative average and 0.75D +/- 0.66 in absolute average. Using the staudard formula described by Hoffer, the accuracy of IOL power calculation in this method was 73% +/- 1.0D / 91.5% +/- 2.0D / +2.77 to -2.31D. 4. There was a significant difference between the error of the A constant 116.2 and that of 116.8(P. 0.05), but wasn't between the error of the A constant 116.2 and that of TI-59 system. 5. In the case of axial length 21mm +/- 0.5, the IOL power calculation by the A constant 116.2 was the most accurate among three groups.

The authors reviewed retrospectively preoperative ocular clinical characteristics, operative methods, postoperative anatomical results and visual rehabilitation for the 24 eyes, retinal detachments following extracapsular cataract extraction (ECCE). The most, common preoperative visual symptom was decreased vision, 19 eyes (79%) and the significant preoperative ocular findings were vitreous opacity 14 eyes (58%) and posterior capsular rupture 14 eyes (58%). The horseshoe tear 11 eyes (46%), atrophic hole 9 eyes (38%) were more comnnonly encountered, and the retinal breaks were principally located in the superotemporal quadrant in 18 eyes (75%), the superonasal quadrant. in 12 eyes (42%). Also, macular detachment 19 eyes (79%) was found most frequently with retinal detachment eyes. The overall anatomic success rate of surgical treatment of retinal detachment after ECCE was 21 eyes (88%). Especially, the visual acuity improved two line or more in II eyes (85%) with posterior chamber intraocular lens (PC-IOL) implantation group. We suggest that the early detection of retinal detachment. after ECCE with complications and proper operations are important to inaprove the postoperative anatomic success rate and the postoperative visual prognosis.

BACKGROUND AND OBJECTIVES: Cancer of the oral cavity is a disease of the head and neck that is difficult to treat. Periodic observation and biopsy are important for its early diagnosis once a premalignant lesion in the oral cavity is confirmed. The purpose of this study was to determine the importance of early excisional biopsy by investigating the histological features of oral leukoplakia and the rate of malignant change in the oral cavity. SUBJECTS AND METHOD: A total of 327 patients who underwent punch biopsy of oral cavity from January 2011 to December 2017 were reviewed retrospectively for the presence of initial gross lesions and for their biopsy results. The histological findings of 6 initial gross lesion groups were compared. Additional excisional biopsies were performed in the seven oral cavity subsites. RESULTS: There were 33 cases of oral leukoplakia. The punch biopsies of 3 of these cases (9.1%) showed malignancy. Additional excisional biopsies were performed in 6 cases, 4 of which were malignant (66.7%). Additional excisional biopsies of the tongue were performed in 14 cases (9.0%), 5 of which (35.7%) were malignant. The rate of atypia in leukoplakia (9.1%) was higher than in other atypia groups. Additional excisional biopsies were performed in 3 cases (100%) of atypia of leukoplakia, all of which were assessed to be malignant. CONCLUSION: For tongue leukoplakia, performing an early excisional biopsy rather than an incisional biopsy is recommendable. Moreover, additional excisional biopsies are needed when the initial biopsy is suggestive of hyperkeratosis, parakeratosis, or atypia.

Hyperglycemia during either global or regional ischemia is widely known to be detrimental, and ischemia induced release of diverse neurotransmitters and the ensuing activation of specific postsynaptic receptors have been suggested to play a important role in the development of ischemic selective vulunerability. This study was undertaken to investigate the influence of blood glucose change on tissue concentration of some catecholamines ; dopamine, norepinephrine, serotonin, of the transient ischemic rat's brain, estimated by high performance liquid chromatography(HPLC) assay system, following transient bilateral forebrain ischemia in the rat's model subjected to 20 minutes of normothermic ischemia by two vesseles occulusion plus profound cortex, hippocampus and striatum respectively by HLPC. The concentrations of catecholamines were significantly decreased in all sampled areas in experimental groups compared with the control group(p<0.05), respectively(average decrease rate : norepinephrine 71%, dopamine 89%, serotonin 80% in frontal cortex ; norepinephrine 71%, dopamine 93%, serotonin 81% in hippocampus ; norepinephrine 33%, dopamine 35%, serotonin 78% in striatum). Dopamine was relatively decreased in concentration in frontal cortex and hippocampus, and serotonin was relatively decreased in striatum. But no statistic significancy(p>0.05) of catecholamines level between each experimental group(hyper-, hypo- and normoglycemic group) according to the change of blood sugar. The results suggested that blood glucose level did not influence the tissue concentration of dopamine, norepinephrine and serotonin in frontl cortex, hippocampus and striatum of transient ischemic rat's brain.

Intracranial schwannoma constitutes 8-10% of all primary intracranial tumors. The majority of them derive from cranial nerves, especially from the vestibulocochlear nerve. Intraparenchymatous schwannoma of the cent ral nervous system, on the other hand, is very rare. We report a rare case of brainstem schwannoma with the review of literature 8.
