We performed an anatomical study on transscleral suture fixation of posterior chamber intraocular lens implantation. Results showed that the relationship of the ciliary sulcus to the overlying posterior surgical limbus differed in the vertical and horizontal meridians. Needles that pierced the ciliary sulcus after being passed perpendicularly through the sclera entered the sclera 0.88+/-0.22mm posterior to the posterior surgical limbus in the vertical meridians and 0.44+/-0.37mm in the horizontal meridians. The scleral exit site of a suture passed from the inside of the eye through ciliary sulcus was 0.90+/-0.12mm posterior to the posterior surgical limbus in the vertical meridians, 0.85+/-0.17mm in the oblique meridians, and 0.45+/-0.10mm in the horizontal meridian.

BACKGROUND: It has been documented that certain prognostic factors may affect the outcomes of the old aged victims by trauma. Considering that trauma is the sixth most common cause of death in people over the age of 65 years and there is a rapid growth of elderly population, it is paramount to understand the prognostic factors when dealing with geriatric trauma patients. Hypothesis and Goals : It can be hypothesized that the prognostic factors should be determined independently between populations being consisted of different races, countries, socio-economic states, cultures, or so on. Thus, study was designed to evaluate the factors affecting the outcomes of elderly Korean trauma patients. METHODS: One hundred forty six patients aged over 65 years were retrospectively reviewed, who visited the Emergency Canter of Korea University from January, 1997 to June, 1998. Of 146 patients, 7 were excluded due to discharge against advice or transfer to the other hospitals. Parameters analysed were age, sex, mechanism of injuries, body region injured, Injury Severity Score (ISS), previous medical illness, hospital morbidity, duration of hospital stay, and cost. Each patient was classified into improved or not-improved groups depending on the outcomes, and young-old or old-old group depending on the age. The factors affecting the hospital stay in improved patients were analyzed in the parameters of previous medical illness, hospital morbidity, multiple injuries, ISS, and age. All statistical tests were conducted with two-tailed levels of 0.05. RESULTS: Of 139 patients, the mean age was 74+/-7.1 years, mean ISS 9.3+/-7.26, mean hospital stay 27+/-27.1 days. Most commonly injured body region was the extremities due to fall from a level surface. Rate of previous illness showed 0.94 medical diseases per person and were aggravated after trauma in 39 patients (60.9%). Hospital morbidity rate was 0.46 incidents per person. There were no differences in age and duration of hospital stay between the improved and the not-improved group. Substantial differences were noted in affected body region, incidence of previous illness, and hospital morbidity between the groups (p=NS). Not-improved group had higher ISS (p<0.05). ISS, previous illness and hospital morbidity affected the duration of hospital stay in the improved group. Hospital stay was 40+/-25.1 days in patients with ISS over 6 while 6+/-8.6 days in those with ISS 5 (p<0.05). Hospital stay in the improved was 26+/-26.9 days while 31+/- 24.8 days in the improved old-old group (P=NS). Hospital stay in the young-old minor trauma (ISS5) patients with previous illness and hospital morbidity was 26+/-10.1 days while 4+/-7.3 days in those without previous illness and hospital morbidity (p<0.05). CONCLUSION: Previous medical illness and hospital morbidity, not age, are predictive of outcomes of geriatric trauma patients with respect to hospital stay. As most of the hospital morbidity was a trauma-induced aggravation of previous medical illness and hospital morbidity contributing poor outcomes can be potentially avoidable, routine aggressive care far the geriatric trauma patients with previous medical illnesses is needed.

As extra-mammary Paget's disease is rare and usually diagnosed at early stage when it is highly curable with surgical resection, it is much rarer to see patients with recurrent metastatic disease. Thrombotic thrombocytopenic purpura in patients with metastatic solid cancer is also a rare disease and may result from bone marrow metastasis or bone marrow necrosis. For the latter, the majority of cases are not eligible for systemic chemotherapy for rapid disease progression and poor performance status. Herein, authors report a patient with thrombotic thrombocytopenic purpura associated with bone marrow necrosis complicating extra-mammary Paget's disease who was successfully treated with docetaxel and carboplatin combination chemotherapy.

Acute acquired comitant esotropia has been used to describe a dramatic onset of a relatively large angle of esotropia with diplopia and minimal refractive errors. The authors experienced two cases of acute acquired comitant esotropia in patients with the age of 28 and 40 years. Sudden diplopia and esodeviation developed in both patients. All ophthalmologic and neurologic examinations including brain MRI showed negative results. Amount of deviation remained constant. We performed recession of both medial rectus muscles. Four weeks after surgery, both patients showed orthotropia without any complaints of diplopia.

Primary pulmonary hypertension is a rare and progressive disease with poor prognosis. Despite much previous studies, there is neither clear explanation in the etiology and the pathogenesis nor confirmative treatment modalities. Its main cause of death is due to the right ventricular failure but the left ventricular function is relatively well preserved. The chest pain mimickig the angina pectoris is common and it is mostly due to the right ventricular ischemia or distension of pulmonary artery, but left ventricular ischemia or infarction is very rarely seen. We experienced a case of primary pulmonary hyperetension with left ventricular hypertrophy that complicated to acute myocardial infarction in 14-year-old male.

PURPOSE: We compared the reproducibility of 201Tl and 99mTc-sestamibi (MIBI) gated SPECT measurement of myocardial function using the Germano algorithm. MATERIALS AND METHODS: Gated SPECT acquisition was repeated in the same position in 30 patients who received 201Tl and in 26 who received 99mTc-MIBI. The quantification of end-diastolic volume (EDV), end-systolic volume (ESV), and ejection fraction (EF) on 201Tl and 99mTc-MIBI gated SPECT was processed independently using Cedars quantitative gated SPECT software. The reproducibility of the assessment of myocardial function on 201Tl gated SPECT was compared with that of 99mTc-MIBI gated SPECT. RESULTS: Correlation between the two measurements for volumes and EF was excellent by the repeated gated SPECT studies of 201Tl (r=0.928 to 0.986; p<0.05) and 99mTc-MIBI (r=0.979 to 0.997; p<0.05). However, Bland Altman analysis revealed the 95% limits of agreement (2 SD) for volumes and EF were tighter by repeated 99mTc-MIBI gated SPECT (EDV: 14.1 ml, ESV: 9.4 ml and EF: 5.5%) than by repeated 201Tl gated SPECT (EDV: 24.1 ml, ESV: 18.6 ml and EF: 10.3%). The root mean square (RMS) values of the coefficient of variation (CV) for volumes and EFs were smaller by repeated 99mTc-MIBI gated SPECT (EDV: 2.1 ml, ESV: 2.7 ml and EF: 2.3%) than by repeated 201Tl gated SPECT (EDV: 3.2 ml, ESV: 3.5 ml and EF: 5.2%). CONCLUSION: 99mTc-MIBI provides more reproducible volumes and EF than 201Tl on repeated acquisition gated SPECT. 99mTc-MIBI gated SPECT is the preferable method for the clinical monitoring of myocardial function.

BACKGROUND: Continuous arterial blood pressure monitoring is a highly effective method in an operation and the intensive care unit. However, the accuracy of the monitoring system could be influenced by the radius and longitude of the catheter. This study was executed to examine the effects of the radius and longitude of a catheter. METHODS: Forty-two pediatric patients scheduled to undergo open heart surgery were selected. After induction of anesthesia, the radial artery pressure was measured by a 22-gauge (1 inch) catheter and the femoral artery pressure was measured by a 20-gauge (1.16 inch) catheter, 22-gauge catheter and 20-gauge (12 cm) catheter in succession. Influences of the radius and longitude were analysed respectively. All values are expressed as mean +/- SD and analysed using the paired t-test; P < 0.05 was considered significant. RESULTS: The systolic pressure of the 20-gauge (1.16 inch) catheter was higher than that of the 22- gauge (1 inch) catheter. The systolic pressure of the 20-gauge (1.16 inch) catheter was higher than that of the 20-gauge (12 cm) catheter. Mean and diastolic pressures were low in the 20-gauge (1.16 inch) catheter, compared with the 20-gauge (12 cm) catheter. CONCLUSIONS: Shorter and/or larger radius catheters could increase the pulse pressure in pediatric patients.

A 57-year-old man presented with weakness in both legs upon awakening after drinking. Magnetic resonance imaging (MRI) of the lumbar spine did not reveal any intraspinal abnormalities but MRI of the pelvis revealed lesions with abnormal intensities with heterogeneous contrast enhancement in both gluteal muscles. Serum creatine phosphokinase was markedly elevated. A diagnosis of lumbosacral plexopathy, complicating rhabdomyolysis was made. With supportive care he recovered well but mild weakness of the right ankle remained at 6 month-follow-up. Pelvic MRI is a helpful diagnostic tool in localizing rhabdomyolysis. Lumbosacral plexopathy should be included in the differential diagnosis of the such cases, presenting with sudden weakness of legs.
