Eleven patients underwent posterior sagittal anorectoplasty(PSARP) as a secondary procedure. Two of them had rectovaginal fistula and another two had rectocutaneous fistula. Six of the rest complained of frequent fecal soiling and the last one had severe anorectal stricture after perineal anoplasty. Five patients had lived with colostomy until the second operations were carried out. The ages at the time of the secondary PSARP were between 7 months and 29 years. Distal colostogram and MRI were taken to evaluate distal colon, position of the rectum and voluntary muscle. All patients had normal sacrum except one who had anorectal stricture. Seven patients, six with fecal incontinence and the other one with rectovaginal fistula had mislocated anorectums. Three patients, two with rectocutaneous fistula, the other one with anorectal stricture, had abdominal approach to obtain enough length of colon for pull-through procedure. With the posterior midsagittal approach, we could manage all the problems, rectovaginal fistulas, rectocutaneous fistulas, strictures and malpositioned rectums, without difficulty. No patients had serious complications except wound infection in one. All patients were satisfied with the results after redo-PSARPs even though normal continence has been achieved in only one patient. Seven patients who had continuous soiling or rectocutaneous fistula, needed no more diapers even though four of them showed fecal staining under stressful condition and the other three showed intermittent fecal leaking less than once a day. The rest three of the patients maintained their continence with support of drugs and/or enemas because of constipation. The PSARP is a popular procedure as a primary operation; however, our results suggested that this procedure also gave us a good opportunity for management of serious complication developed after primary anoplasties.

Fracture of the femoral neck occurred after internal fixation of intertrochanteric fracture of the femur is very rare and have been described previously in terms of stress fracture, stress-riser fracture, Youngs modulus fracture or iatrogenic fracture in the literature. This fracture documented about 20 cases in the English literature and usually occurred in elderly patients with osteoporosis and it always occur in the subcapital region. We report a case of subcapital stress fracture of the femur occurred after internal fixation with compression hip screw of intertrochanteric femur fracture.

BACKGROUND AND OBJECTIVES: Primary intervention by stent implantation during acute myocardial infarction is a novel strategy to provide better myocardial perfusion compared to thrombolysis or baloon angioplasty. We aimed to assess the reperfusion achieved by primary stenting, employing TIMI frame count for more objective and quantitative measurement. MATERIALS AND METHOD: Measurements for number of frames required to opacify standardized angiographic landmark branch(TIMI frame count) were determined for the coronary arteries of 77 normal controls and 65 patients with acute myocardial infarction who underwent primary stenting within 12 hours of symptom onset. RESULTS: In normal subjects, TIMI frame count for left anterior descending artery(LAD) was 1.3 times of mean count of right coronary artery(RCA) and left circumflex artery(LCx), and significant less than that of TIMI study(22.3+/-4.9 vs 36.2+/-2.6, p<0.05). TIMI frame count for RCA and LCx was similar to results of TIMI study. In infarct related arteries(IRA), corrected TIMI frame count(CTFC) after primary stenting was similar to those of normal control. Frame counts of RCA was larger compared to that of normal control, but statistically insignificant(23.0+/-7.5 vs 17.6+/-3.5, p>0.05). There was no difference of CTFC of non-infarct related arteries between patients and normal controls. CONCLUSION: The TIMI frame count of LAD artery in normal Korean subjects was significantly less than that of American counterpart. In patients with acute myocardial infarction, primary stenting appeared to provide improved coronary flow similar to that observed in normal subjects, as measured by TIMI frame counting.

Aneurysm of the splenic artery are the third most common intra-abdominal aneurysm, following aneurysms of the infrarenal aorta and iliac arteries. Splenic artery aneurysms (SAA) are the most frequent visceral artery aneurysms and account for more than two thirds of all lesions. Incidence of SAA are rare clinical entities(0.01-0.2%) that carry risk of rupture and fatal hemorrhage(35-100%). Fibroblastic dysplasia and atherosclerosis is fecund in the majority, and the fact that these aneurysms developes more commonly in female. Most patients are asymptomatic and the diagnosis is generally made incidentally. The treatment of patient with known SAA is dictated by several factors, including location, age, sex, present of symptom, size, pregnancy. We report ruptured splenic artery aneurysm with hemoperitoneum and review of the literature.

The authors have made a CD-ROM titled 'Atlas of Pathology (AP)' for medical students to understand histopathologic findings with ease. We used a 35 mm film scanner to convert an existing file into digital images. A pathologist and two professional programmers collaborated to create the program 'AtlasMaster 1.0' based on (IBM) PC for organization of previously captured digital images. Minimum system requirement for the 'AP' was Pentium II 166 MHz, 32 MB RAM, Windows 95 or 98, 800 600 resolution, 16-bit color, 20 speed CD-ROM drive. The 'AP' was composed of a execution file (Pathology_Atlas.exe), a DB file (pathology.mdb), and reference files (*.bmp, *.jpg, *.txt). The DB file contained fields for chapter, section, disease entity, and information for location of reference files. About 1,000 color images for various kinds of gross and microscopic pictures were stored in the CD-ROM and those were classified according to the chapters, sections, and disease entities. The 'AP' was easy to manipulate, and had advantages of self-learning for students. It could be applied to other fields in which many images were dealt with, such as histology, radiology, endoscopy, dermatology, and plastic surgery. The 'AP' was handy and very useful for medical students to study pathology and it would be a powerful self-learning tool.

BACKGROUND: Endotoxins play important roles in the pathophysiologic alterations associated with sepsis so the authors examined the effects of hydroxocobalamin, NW-nitro-L-arginine-metyl ester (L-NAME) and aminoguanidine on thiopental-induced contractile responses of lipopolysaccharide (LPS)-treated and control rat aortic rings. METHODS: Aortic ring preparation was obtained from LPS-treated (1.5mg/kg, i.p. for 18h) rats. Cumulative doses of thiopental (10-4~3x10- 3M) were added to construct contraction response curves. Hydroxocobalamin (10-5M), L-NAME (10-6M) or aminoguanidine (10-6M) were added as NO scavenger or as NOS inhibitors. Contraction curves by cumulative doses of thiopental (10-4~3x10-3M) were remeasured after treatment of NO scavenger or NOS inhibitors. Statistical significances (p<00.05) were analyzed according to data characteristics by Student's t-test, paired t-test or ANOVA. RESULTS: The vascular responses of cumulative thiopental (10-4~3x10 3M) administration were dose- dependent contraction and LPS-treated rat was less contracted (p<00.05). There was significant increment on vascular contraction induced by thiopental after hydroxocobalamin pretreatment in LPS-treated rat (p<0.05), in spite of L-NAME, aminoguanidine pretreatment was failed to increase contractile forces in control and LPS-treated rats. CONCLUSIONS: From these results, viewed from maintenance of vasomotor tone in septic state, it is suggested that hydroxocobalamin may be candidate for vasopressor during usual induction of general anesthesia.
