The present study was carried out to clarify the anatomical changes of lumbar intervertebral discs by aging. Anterior height, posterior height, anteroposterior diameter of intervertebral discs were measured on 512 normal plain lateral radiographs of lumbosacral spine. And the indices of disc wedging and relative disc height were calculated. There was a cephalocaudal gradient of increase in the indices of disc wedging in all age groups. The indices of relative disc height were constant at all lumbar levels. These suggest that the lower disc is more wedge shaped and the height of discs changes in the constant ratio with that of vertebral body.

The prognostic factors for extrahepatic biliary atresia (EHBA) after Kasai portoenterostomy include the patient's age at portoenterostomy (age), size of bile duct in theporta hepatis (size), clearance of jaundice after operation (clearance) and the surgeon's experience. The aim of this study is to examine the most significant prognostic factor of EHBA after Kasai portoenterostomy. This retrospective study was done in 51 cases of EHBA that received Kasai portoenterostomy by one pediatric surgeon. For the statistical analysis, Kaplan-Meier method, Logrank test and Cox regression test were used. A p value of less than 0.05 was considered to be significant. Fifteen patients were regarded as dead in this study, including nine cases of liver transplantation. There was no significant difference of survival to age. The age is also not a significant risk factor for survival in this study (Cox Regression test; p = 0.63). There was no significant difference in survival in relation to the size of bile duct. However, bile duct size was a significant risk factor for survival (Cox Regression test; p = 0.002). There was a significant difference in relation to survival and clearance (Kaplan-Meier method; p = 0.02). The clearing was also a significant risk factor for survival (Cox Regression test; p = 0.001). The clearance of jaundice is the most significant prognostic factor of EHBA after Kasai portoenterostomy.

Capsule contraction syndrome is severe constriction of the anterior capsular opening and equatorial capsular bag diameter after extracapsular cataract surgery. It is relatively common in patients with continuous curvilinear capsulorhexis, but rarely in can-opener capsulotomy or anterior radial capsular tears. It is due to capsular bag contraction from fibrous dysplasia of residual lens epithelial cells with weakened zonular resistance. We experienced a case of capsule contraction syndrome in a 72-year old woman with retinitis pigmentosa, who had phacoemulsification following an intact 5.0mm-continuous curvilinear capsulorhexis 4 months before. After successful YAG laser radial anterior relaxing capsulotomy, her visual acuity restored to 0.3, limited by cystoid macular edema.

Lymphangiectasia(acquired lymphangioma) is characterized clinically by the presence of a circumscribed eruption of thin-walled, translucent vesicles which closely resemble frog spawn in appearance. This rare disorder may arise as a result of acquired lymphatic obstruction secondary to surgery, irradiation, chronic recurrent infection, chronic scarring, or trauma. Herein, we report a case of atypical lymphangiectasia at the site of an abdominal scar in a 70-year-old female. She developed a dark red-colored, pedunculated papule, 2 years after a total abdominal hysterectomy and post-operative irradiation for carcinoma of the uterine cervix. Histopatholgical findings showed multiple irregularly shaped cystic dilatated cells lined by a single layer of endothelium in the dermis. Immunohistochemical staining with factor VIII-related antigen showed negative results. A lymphangiogram showed signs of acquired lymphatic obstruction.

Three parameters (lumbar lordosis, lumbosacral and sacral inclination angle) were measured on 512 normal plain lateral radiographs of lumbosacral spine and the patterns of change during aging were studied. The following results were obtained. 1. The lumbar lordosis angle showed a tendency to increase with age. But a brief decrease was observed after the 6th decade in both sexes, between the 2(nd) and 3(rd) decades in males, and between the 3(rd) and 4(th) decades in females. The lumbar spines of females were generally more lordotic than those of males. 2. The lumbosacral angle appeared to increase with age. The angle in males showed a decline between the 2nd and 4th decades while the angle in females decreased after the 6th decade. Males usually had greater angles than females. 3. The sacral inclination angle continued to increase until the 6th decade, after which a decrease was noted. The angle in females was generally greater than that in males. These results showed that all three angles varied with age, and the pattern of change differed between male and female.

We report herein a gigantic case of verrucous hemangioma occuring in a 15 year-old school- boy. The lesion was a dark red colored, 10.0 x 6.0 x 0.8cm sized, verrucous surfaced, hemangiomatous tumor affecting the posterior aspect of the right thigh. At birth an erythematous macule appeared and insidious]y increased or extended with age. In the last 6 months, it had grown rapidly to the size of the present lesion with a smaller satellite one, assumably ascribing to the repeated minor trauma or pressure. Histological findings from the totally excised lesion showed epidermal hyperplasia with irregular acanthosis and papillomatosis and diffuse marked proliferation and dilatation of blood vessels from the upper dermis to subcutaneous fatty tissue. Wide excision was done. There was no relapse after about one years postoperative follow up.

BACKGROUND: Tracheal intubation commonly results in sympathetic stimulation manifested by increased heart rate and arterial blood pressure. This study was carried out to determine whether lightwand would result in less hemodynamic changes than direct laryngoscopy. METHODS: With informed consent, fourty healthy female patients scheduled of elective surgical procedures were randomly allocated into two groups; lightwand (LW) or direct laryngoscopy (DL) group. Mean arterial pressure (MAP) and heart rate (HR) were recorded upon arrival. Under a standardized anesthetic technique, the patients were intubated either with no. 3 curved blade direct laryngoscopy (DL group) or with lightwand (LW group). The MAP and HR were recorded before intubation and every 1 minutes following intubaion. Time to intubation (TTI) was also recorded. All patients were intubated by a same fourth grade resident. RESULTS: Fourty patients were studied. Every intubation was successed in first attempt. The TTI was significantly shorter in LW group. Even while there was no significant difference in HR changes, there was significant difference in the increase of MAP following intubation. The increase of MAP was significantly greater with DL than with LW. CONCLUSIONS: This study suggests that lightwand intubation requires shorter TTI and may give rise to less blood pressure change than direct laryngoscopy. So we found no difference in disadvantage and may offers advantage in terms of hemodynamic stability.

We report four cases of spontaneous intracranial hypotension that were investigated by radionuclide cisternography Tc-99m-diethylenetriamine pentaacetic acid radionuclide cisternography of all our patients showed direct sign of cerebrospinal fluid leakage as well as indirect signs of less activity than expected over the cerebral convexities and rapid appearance of bladder activity. The headache of all patients was eventually controlled with bed rest and hydration.
