The heterotopic and tissues may be divided into two categories: those that are found in the head and neck region, and those that arise elsewhere. The latter type is rare and most cases are found in the lungs of patients with neural tube defect, particularly anencephaly. Our report descrives anencephalic male infant with heterotopic glial nodules in both lungs. The largest nodule is 2x1.5x1 cm, locates in the lower lobe of the left lung, and has a round gray-white cut surface with cystic spaces. Microscopically, the nodules consist of irregularly arranged astrocytes and glial fibers, in which are embedded gland-like or cystically dilated bronchioles. The astrocytes and glial fibers are strongly positive for glial fibrillary acidic protein and show astrocytic filaments on electron microscopy. This will be an additional case supporting the amniotic fluid aspiration/implantation theory of pathogenetic mechanism of distal heerotopic glial tissue.

Recently, [I-123]IPT SPECT has been used for early diagnosis of Parkinson's patients(PP) by imaging dopamine transporters. The dynamic time activity curves in basal ganglia(BG) and occipital cortex(OCC) without blood samples were obtained for 2 hours. These data were then used to measure dopamine transporters by operationally defined ratio methods of (BG-OCC)/OCC at 2 hrs, binding potential Rv=k3/k4 using graphic method or RA= (ABBG-ABOCC)/ABOCC for 2 hrs, where ABBG represents accumulated binding activity in basal ganglia(integral 0 120minBG(t)dt) and ABOCC represents accumulated binding activity in occipital cortex(integral 0 120minBG(t)dt). The purpose of this study was to examine the IPT pharmacokinetics and investigate the usefulness of simplified methods of (BG-OCC)/OCC, RA, and RA which are often assumed that these values reflect the true values of k3/k4. The rate constants K1, k2, k3 and k4 to be used for simulations were derived using [I-123]IPT SPECT and aterialized blood data with a standard three compartmental model. The sensitivities and time activity curves in BG and OCC were computed by changing K1 and k3(only BG) for every 5min over 2 hours. The values (BG-OCC)/OCC, RA, and Rv were then computed from the time activity curves and the linear regression analysis was used to measure the accuracies of these methods. The rate constants K1, k2, k3, k4 at BG and OCC were 1.26+/-5.41%, 0.044+/-19.58%, 0.031+/-24.36%, 0.008+/-22.78% and 1.36+/-4.76%, 0.170+/-6.89%, 0.007+/-23.89%, 0.007+/-45.09%, respectively. The Sensitivities for ((delta S/S)/(delta k3/k3)) and ((delta S/delta S)/(delta K1/K1)) at 30min and 120min were measured as (0.19, 0.50) and (0.61, 0.23), respectively. The correlation coefficients and slopes of ((BG-OCC)/OCC, RA, and Rv) with k3/k4 were (0.98, 1.00, 0.99) and (1.76, 0.47, 1.25), respectively. These simulation results indicate that a late [1-123]IPT SPECT image may represent the distribution of the dopamine transporters. Good correlations were shown between (BG-OCC)/OCC, RA or Rv and true k3/k4,, although the slopes between them were not unity. Pharmacokinetic computer simulations may be very useful technique in studying dopamine transpoter systems.

PURPOSE: This study is to verify the correlations between xerostomia, oral health quality of life, and knowledge about water intake among community-dwelling older adults and to suggest basic data for the development of oral health enhancement programs to improve the quality of life in the elderly. METHODS: A convenience sample of 112 elders was recruited in W city, Gangwon-do from July to August 2017. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, and Pearson's correlation coefficients with SPSS/WIN 23.0 Program. RESULTS: The mean age of the subjects was 73 years old. As the score of knowledge about water intake was average 3 point (out of ten), the knowledge about physical symptoms in case of water deficiency was very insufficient. Xerostomia showed negative correlations with the oral health quality of life (r=−.379, p < .001) and knowledge about water intake (r=−.228, p < .016). CONCLUSION: For the relief of xerostomia having effects on the oral health quality of life in the elderly, it would be necessary to develop and apply oral health enhancement programs including the recommendation of water intake, and then to verify the effects.

PURPOSE: Acute diarrhea in young children is a major problem in pediatric hospitals worldwide. We evaluated the clinical efficacy of orally administered Lactobacillus acidophilus in the treatment of acute diarrhea in children. METHODS: From September 2002 to July 2003 at National Police Hospital 41 children aged 3 months to 5 years with acute diarrhea were enrolled in this study. The patients were randomized to one of two groups to receive either 0.5 x 10(8) colony forming unit (CFU) of L. acidophilus or matching placebo on admission and every 8 hours during hospitalization. RESULTS: The mean duration of diarrhea in all 41 children was decreased (p=0.001) in the L. acidophilus (40.5 hours) group compared to the placebo (56.6 hours) group. Stool frequency was also reduced (p=0.01) on the 3rd day in the L. acidophilus group. Rotavirus was identified in 58% of the patients. The decrease of duration of diarrhea was more significant in rotavirus-negative patients (p=0.002) compared to the rotavirus-positive patients (p=0.027). CONCLUSION: L. acidophilus shows to be an effective therapeutic agent in acute diarrhea in children. Further studies are needed to confirm the present findings.

OBJECTIVE: To estimate the motor unit numbers in normal adult hand muscles using manual incremental technique and F-wave technique. METHOD: We estimated the motor unit numbers in abductor pollicis brevis muscles of twenty normal adults. In manual incremental technique, we estimated the motor unit numbers using motor unit count program setted in electrodiagnostic equipment (Dantec, Keypoint). In F-wave technique, we estimated the motor unit numbers dividing maximal M-potential amplitude by mean amplitude of surface motor unit action potential. RESULTS: There was no significant difference of motor unit numbers between right and left abductor pollicis brevis in both manual incremental and F-wave technique. Motor unit numbers using F-wave technique were significantly greater than motor unit numbers using manual incremental technique. CONCLUSION: The difference of motor unit numbers using manual incremental technique and F-wave technique was considered as a difference of functional electrical stimulation. F-wave technique was more physiologic and functional method of motor unit numbers estimation than manual incremental technique.

PURPOSE: Transforming growth factor (TGF)-beta 1 stimulates collagen synthesis in human corpus cavernosum smooth cells (HCCSMC). We studied whether an antisense TGF-beta 1 oligodeoxynucleotide changed TGF-beta 1 mRNA expression and its related collagen synthesis. MATERIALS AND METHODS: The HCCSMC were cultured primarily from three impotent patients. Expression of TGF-beta 1 mRNA was induced by phorbol 12-myristate 13-acetate (PMA) 0.2 micro gram/ml in the presence or absence of antisense TGF-beta 1 oligodeoxynucleotide (5'-GGGCGGCATGGGGGA-3') 20 micro gram/ml. The effect of the antisense oligodeoxynucleotide on TGF-beta 1 mRNA and collagen I synthesis were measured by RT-PCR or Northern blot analysis. RESULTS: The expression of TGF-beta 1 mRNA in response to PMA was inhibited by treatment with the antisense oligodeoxynucleotide. Collagen I expression was also induced by PMA treatment, and the antisense oligodeoxynucleotide downregulated this expression. CONCLUSIONS: Antisense TGF-beta 1 oligodeoxynucleotide can suppress the expression of TGF-beta 1 and TGF-beta 1-induced collagen I synthesis in HCCSMC.

An intravaginal foreign body of long duration can lead to infection and ulceration. Foul-smelling, bloody vaginal discharge, and pelvic pain may indicate the presence of an intravaginal foreign body and symptoms may be referred to the bladder or rectum. But these clinical features are nonspecific and a number of diagnostic modalities may fail to detect the presence of the foreign body. Moreover, long-standing intravaginal foreign body may be difficult to distinguish from an advanced cervical cancer especially in uninformed cases. We present a case of a 41-year-old female who suffered from an aggravating chronic pelvic pain and malodorous dirty vaginal discharge. Initially the advanced cervix cancer complicated with recto-vaginal fistula was suspected. But results of repeated biopsies were benign and symptoms were improved by intravenous antibiotics. Finally the embedded foreign body in the posterior fornix was detected and successfully removed. It was proved as the grip of an umbrella. We concluded that a high index of suspicion is very important for the correct diagnosis of long-standing vaginal foreign body especially in uninformed cases.

The amniotic band syndrome is rare congenital deformity, presumably due to rupture of amniotic sac during the early pregnancy and appears to cause fetal injury through deformation, malformation, or disruption. This syndrome is given many names yet follows a clearly defined clinical pattern. The diagnosis was based on sonographic visualization of either amniotic bands or bands associated with fetal deformation or deformities in nonembryologic distribution. Recently, we experienced a case of amniotic band syndrome, in which partial absence of cranial bone, asymmetric facial dysmorphism and amputation of right lower leg were detected. At our best knowledge, this is one of few case describing prenatal ultrasound diagnosis of amniotic band syndrome in Korea. So, we present this case with a brief review of the literatures.
