The determination of the degree and ability of recovery of obstructive hydronephrosis is important in treatment and prediction of prognosis. Among the various methods in determination of the status of kidney, intravenous pyelography is the most important tool to evaluate the morphological and functional changes of kidney in vivo. The purpose of this experiment was the determination of process and recoverability of hydronephrosis depend on duration of unilateral uretreal obstruction. For the experiment, 32 rats were divided into 2 groups; the first group of 12 rats were used to determine the process of hydronephrosis during 1 to 4 weeks of unilateralureteral ligation and the second group of 20 rats were used to determine the recoverability of hydronephrotic kidney depend on same duration of ureteral ligation following relief of ligation. Intravenous pyelography as undertaken and renal angiography, gross and microscopic examination were added. The results obtained are summarized as follows; 1. Kidney enlargement and pelvic dilatation were progressively increased with a relation to duration of ureteral obstruction until 4 weeks. 2. Renal excretory function is not impaired until 3 weeks obstruction, but rapidly impaired to nonfunctioning in 4 weeks obstruction. 3. Renal recovery was possible following relief of ureteral ligation within 3 weeks of ureteral obstruction, but histopathological and functional recovery were impossible in 4 weeks of ureteral ligation. 4. There is no direct correlation between duration of obstruction and recoverability following relief within 3 weeks of uretral obstruction. 5. Intravenous pyelographyis a simple and accurate method to determine the degree of obstructive hydronephrosis and to evaluate morphological and functional recovery of kidney following relief of obstruction.

On the pulse from the trauma transiting to posterior side of the orbit, orbital fractures are occurred throughthe weak point of the orbital wall. Invagination of soft tissue or entrapment of muscles may be associated withorbital fracture. In condition of inaccurate diagnosis, appropriate surgical repairment is impossible andcomplications such as diplopia or enophthalmia are developed. CT scan is diagnostic procedure which demonstratesaccurately the site and stage of orbital fracture, and its associated findings. The authors has been studied in 21orbital CT scans to evaluate the relative value of plain X rays and CT scans in the diagnosis of orbital fracturesduring the period from January 1982 to September 1985. The conclusions were as follows: 1. Diagnostic rate was100% by CT, 40% by initial and 80% by retrospective interpretation of conventional X-ray films. 2. Low X-raydiagnostic rate of medical wall fractures(26.7%) was due to thinness of the bone. 3. Medial wall fractures wereassociated with floor fractures in 46%. 4. Orbital soft tissue injuries and abnormalities of PNS were preciselyevaluated by CT scan.

Fibrous dysplasia is a benign bony disorder that contains trabeculae of poorly calcified primitive bone formed by osseous metaplasia. It is also characterized by replacement of normal spongiosa by abnormal fibrous tissues. We retrospectively analyzed the computed tomographic (CT) findings of 29 cases with clinically and radiologically diagnosed craniofacial fibrous dysplasia. In 2 cases, only cranial bones were involved and in 7 cases only facial bones were involved. Involvements of both cranial and facial bones were noted in the remained 20 cases. The commonly involved bones in the decreasing order of frequency were as follows: frontal, sphenoidal, ethmoidal and temporal bones in cranium and maxilla, zygoma, lacrimal bones and mandible in facial bones. Even though plain films are enough to diagnose the fibrous dysplasia, we think that CT is useful in more accurate diagnosis by demonstrating amorphous "ground-glass" appearance in the lesion and defining the exact extent of craniofacial fibrous dysplasia.

PURPOSE: To report pathological, histochemical, ultrastructural, and spectrographic analysis of explanted hydrophilic acrylic intraocular lenses obtained from patients who had visual disturbances caused by postoperative opacification of the IOL. METHODS: Forty-three hydrophilic IOLs (ACRL-160, Ophthalmed Inc.) were explanted from 39 patients with decreased visual acuity because of opacification of the IOL itself. All explanted IOLs were examined grossly and by light microscopy. Full-thickness sagittal sections of the optics of the randomly selected 10 IOLs were stained with the von kossa method (special stains for calcium). One of these sectioned IOLs was not stained, and submitted for scanning electron microscopy and energy dispersive X-ray spectroscopy. RESULTS: Microscopic analysis revealed multiple fine, granular deposits within the lens optics and haptics, and these deposits were stained positively with the von Kossa method. They were varible in size, and unevenly distributed in the optics on the scanning electron microscopy, and energy dispersive X-ray spectroscopy of the internal substance of IOL demonstrated the presence of calcium within the deposits. CONCLUSIONS: We evaluated 43 explanted opacified ACRL-160 lenses, and have demonstrated that the opacification was caused by the presence of granular deposits within the IOL. The deposits have the component of calcium.

We reviewed the computed tomography (CT) of 32 patients with upper lobe collapse to assess the significance of small atypically redistributed pleural effusion (ARPE) in distinguishing the bronchogenic carcinoma (BC) form tuberculosis (TB). Upper lobe collapse was caused by BC in 21 and by TB in 11 of the 32 patients. Small ARPE was Present in 14 of 21 patients with BC and two of the 11 patients with TB, Among 16 patients with small ARPE, CT showd mediastinal invasion in 11 (69%) patients and mediastinal lymphadenopathyn 6 (38%). Our results suggest that small ARPE associated with upper lobe collapse can be used a an auxiliary sign in the differential diagnosis between BC and TB.

OBJECTIVE: To evaluate factor XII deficiency in patients with recurrent spontaneous abortion and its relation to aPTT. MATERIAL AND METHOD: Factor XII was analyzed by clotting method. RESULTS: Of 70 patients with recurrent spontaneous abortion, there were 35 cases of factor XII deficiency. Among them, there were only 3 cases of prolonged aPTT. CONCLUSIONS: It is still unclear whether factor XII deficiency is related to recurrent spontaneous abortion. Molecular approaches should be used to understand further the causal relationship. But based on this result, in the workup of patients with recurrent spontaneous abortion, factor XII should be included. aPTT is not likely to represent the abnormality of factor XII.

PURPOSE: Despite acceptance of laparoscopic totally extraperitoneal (TEP) repair for repair of inguinal hernia, it is still considered to require a prolonged learning curve. We hypothesized that there would be differences in the learning curve for laparoscopic TEP repair among beginner surgeons with or without a supervisor. The current study was conducted to observe the learning curve for laparoscopic TEP repair performed by a surgeon without a supervisor. METHODS: A retrospective analysis of the consecutive 143 patients was conducted to document patients' demographics, hernia types, operative time, and operative outcomes after the operation. Patients were divided into 7 consecutive groups, each comprising 20 patients. RESULTS: The mean age of the study population was 52.5 years (+/- 18.9 SD), ranging from 16 to 89 years. The learning curve of this technique was almost horizontal throughout the time course. The mean operative time was quite stable among each group. Comparison of the mean operation time and the length of hospital stay among each group did not show significant differences. There was one recurrence in group V. CONCLUSION: The learning curve for laparoscopic TEP repair is not that prolonged if there is an experienced specialized supervisor and opportunities to observe the entire procedure performed by the supervisor are available. It is not the laparoscopic instrument skills but the way the procedure is performed that is important for successful outcomes.

PURPOSE: The purpose of this study was to investigate disease prevalence, parent's educational needs, and disease management according to severity of respiratory infections in early childhood. METHODS: Participants for this study were 173 mothers whose child was admitted to I university hospital in Seoul and whose child was an infant or toddler. Data were collected from December, 17, 2014 to February, 15, 2015 using self-report structured questionnaires. Data were analyzed using IBM/SPSS 21.0 program. RESULTS: There were significant differences in the severity of respiratory infection according to neonatal admission due to dyspnea, feeding type, atopic dermatitis in the infant or allergic disease in father and siblings. Parent's educational needs for the severe respiratory infection group were higher than for the non-severe group. Parent's disease management for the severe respiratory infection group was lower than the non-severe group. CONCLUSION: As important care factors in neonatal admissions include dyspnea, cow milk feeding, eczema, family history of allergies, parent's educational needs and disease management, they should be considered when caring for young children with respiratory infections and their parents.
