The anthelminthic effect of phenylene-diisothiocyanate-(1,4)(=Jonit) was studied on the eighty three cases infected with Ancylostoma duodenale. For the evalution, the number of eggs per gram of feces on all these cases was calculated before treatment. The follow-up for the egg reduction was carried out over a period of four weeks. The sixty-seven cases were treated in dosage schedule of 3 x 100 mg every 12 hours. The cure rates - the rate of negative conversion of eggs - was 74.6 percent and the total egg reduction rate of 94.2% was obtained. The ten out of 14 cases treated in the dosage schedule of 2 x 100 mg every 12 hours showed 100% egg reduction and the cure rate was 71.4%. In this group. the total egg reduction rate of 78.6% was noted. In the dosage schedule of 2 x 50 mg every 12 hours the remainder, two out of total 83 cases showed 100% egg reduction. Side effects were observed as being mild, 51 cases (56.6%) were free of side reactions and the most frequently noted side effects were vertigo and diarrhea. From the above results, it is concluded that Jonit is an effective antheminthic against Ancylostoma duodenale and its effectiveness is quite equivalent to that of a known recommended anti-hookworm products.

Hyung-Joon JOO ; Gyu Hong SHIM
Neonatal Medicine 2022;29(1):46-54
Purpose:
The study aimed to examine whether prophylactic surfactant replacement therapy (SRT) with less invasive surfactant administration (LISA) by tracheal catheterization in a group of spontaneously breathing preterm infants would improve clinical outcomes compared to prophylactic SRT with the INtubation-SURfactantExtubation (INSURE) method.
Methods:
We compared 20 spontaneously breathing preterm infants, 25 to 29 weeks of gestation or with a birth weight of less than 1,250 g, treated with prophylactic SRT using a gastric tube (LISA group), to the 20 spontaneously breathing preterm infants matched by gestational age and birth weight, managed with prophylactic SRT via the INSURE method (INSURE group, historical control).
Results:
The LISA group had lower rates of mechanical ventilation (MV) 72 hours after birth (P=0.019) and at any time (P=0.025), lower frequency of bradycardia during SRT (P=0.031), and lower median duration of MV than the INSURE group (P=0.038). In multivariate analysis, the LISA method was associated with a significantly lower likelihood of receiving invasive ventilation during hospitalization (odds ratio [OR], 0.029; 95% confidence interval [CI], 0.001 to 0.938; P=0.046) and a decreased frequency of bradycardia during SRT (OR, 0.020; 95% CI, 0.001 to 0.535; P=0.020) as compared to the INSURE method.
Conclusion
Prophylactic SRT using LISA via tracheal catheterization in preterm infants may significantly reduce exposure to MV during hospitalization and bradycardia during surfactant administration.

Brain size is a useful parameter describing ontogenic character and function. Despite its potential contribution to functional study and diagnosis of disease, it has been hampered by poor assessment tools in vivo and postmortem changes. Recent development of medical imaging techniques such as MRI and CT enable us to understand brain structures in vivo. Many morphometirc studies of the brain has given us new insights in the field of functional neuroanatomy and neuropsychiatric diseases. In spite of these advances, volumetric data of normal Korean brain is not available yet. As an initial approach to Korean standard brain size, we measured the cerebellar volume between 20 and 80 years old Koreans. The MRI films free from lesions in brain was analyzed and measured by NIH image program. The Korean cerebellar volume were ranged between 86.2cm(3) and 141.3 cm(3) and average male cerebellum volume was significantly larger than that of female[male : 118.2+/-11.2cm(3)] > female : 108.0+/-9.6cm(3), P=0.1021E-07<0.05]. And we could not find volume change according to aging process. This is the first report on normal Korean cerebellar volume and the presence of gender difference in the Korean cerebellar volume. These data will be used for the standard useful in studying cerebellar function and cerebellum associated disorders in the future.

Infection in primary total hip arthroplasty may cause catastrophic results and is the major reason for implant failure. The purpose of this study was to evaluate the utility of the hip joint fluid culture as a method of predicting the possibility of a hip joint infection by calculating the sensitivity, specificity and accuracy. We performed 628 primary total hip arthroplasty and aerobic and anaerobic bacterial cultures for hip joint fluid between January 1989 and June 1996. The hip joint fluid culture was routinely performed to evaluate the utility of the femoral head for bone banking. Thirty-two cases out of the 628 hips showed positive intraoperative culture and 596 cases showed negative intraoperative culture. The isolated organisms from 32 positive cultures were 11 for Staphylococcus aureus, eight for Staphylococcus coagulase negative, seven for Enterococcus, three for E.coli and one each for Enterobacter, Acinetobacter and Pseudomonas. Anaerobic culture was negative in all cases. In the positive intraoperative culture cases, none had delayed infection during the follow-up period. But in the negative intraoperative culture cases, one case had acute infection and two cases had delayed infection. In the case with acute infection, Staphylococcus aureus was isolated and on two cases with delayed infection, Enterococcus and Staphylococcus coagulase negative were isolated, respectively. All 32 positive culture cases were fa~lse positive and 595 negative culture cases were true negative and one negative culture case was fa~lse negative. The sensitivity of the hip joint culture was 0%, the specificity was 94.9% and the accuracy was 0%. The specificity of hip joint fluid culture in primary total hip arthroplasty was high, hut the sensitivity score was zero. Therefore, the hip joint fluid culture should not be used for a routine check of infection status in primary total hip arthroplasty. We recommend the hip joint fluid culture in revision arthroplasty or hips in which infection is clinically suspected.

SUMMARY OF LITERATURE REVIEW: Many authors haute described the association between lumbar disc degeneration and segmental instability but it has not been delineated in detail. OBJECTIVES: To compare the MRI assessment of disc degeneration with the conventional plain X-ray evaluation of the intervertebral disc, in order to study lumbar segmental instability. MATERIALS AND METHODS: In 75 patients with low back pain and/or sciatica, we analyzed disc space height, angular displacement, and horizontal displacement on plain radiographs of the lumbar spine. These parameters were compared with the grade of disc degeneration as evaluated by magnetic resonance Imaging. STUDY DESIGN: We analyzed the association between grade of disc degeneration as evaluated by magnetic resonance imaging assessment and segmental instability as evaluated by plain radiographs of the lumbar spine. RESULTS: Disc space height was decreased In proportion to the grade of disc degeneration. Angular displacement was increased according to the grade of disc degeneration, but significantly less with severe degeneration, accompanied by a tendency to stabilization of the motion segment. Horizontal displacement was not correlated with the grade of disc degeneration CONCLUSIONS: The incidence of lumbar segmental instability increased in proportion to the grade of disc degeneration but significantly decreased with severe disc degeneration.

To estimate the clinical usefulness of a newly developed soft contact lens, Hyper II(R) soft contact lens which is a product of 2-hydroxyethylmethacrylate and special cross linking agents by International Contact Lens Lab., Seoul Korea, clinical observations were carried out in 89 patients(154 eyes) during the follow up period of 3 months from April 1985 to February 1986. Excellent corrected visual acuity(over 1.0) was obtained in 134 eyes(87%). The most common subjective symptom after wearing contact lens was foreign body sensation, but this symptom had diminished during the follow up period. Twentyfour eyes discontinued wearing the lens because of lens related problems including lens deposit(11 eyes), lens lost(3 eyes), foreign body sensation(3 eyes), handling difficulty(2 eyes), lens torn (1 eyes) et al. It can be suggested that Hyper II(R) soft contact lens is clinically available with excellent improvement of visual acuity and few complications, either subjective or objective, which might influence wearing contact lens. Long-term follow up, however, might be necessary to understand and reduce the late complications of this soft contact lens.

Ossifications of the ligamentum flavum(OLF) and the posterior longitudinal ligament(OPLL) are uncommon clinical entities as a cause of the progressive compression myelopathy or radiculopathy. Although there are considerable literatures concerning OPLL or OLF in cervical and thoracic spine, there are only a few references about OPLL or OLF in the lumbar spine. OLF and OPLL have been reported that they may lead to severe complication only with a minor trauma or even without trauma, such as paraplegia. The authors have experienced 2 cases of OLF accompanied by OPLL In the lumbar spine, who were treated with decompressive laminectomy and excision of ossified ligaments. For its rarity of OLF and OPLL in the lumbar region, we report here with review of literature.
