We experienced a case of adenocarcinoma arising in sacrococcygeal teratoma. The patient was a 52-year-old woman. She was admitted due to one month of sacral pain. She had a sacral mass since birth. On physical examination, anal fistula was present at the perianal area and pus drainage was noted. MR image showed multiple variable-sized cysts with inhomogeneous density. Resected specimen, mesuring 12.5 7.0 cm in diameter, showed multiple variable-sized cystic lesions admixed with grayish solid portion. The cysts contained mucoid material. The microscopic examination showed mature teratoma composed of cysts lined by pseudostratified ciliated columnar epithelium, intestinal mucosa, mature cartilage, bone, and fat tissue. A moderately differentiated adenocarcinoma developed from the cystic area in the mass.

Intraosseous lipoma is a very rare primary tumor of the bone. We report four cases of intraosseous lipoma. The patient ranged in age from 34 to 59-year-old (median age: 35 year-old). There were three men and one woman. All of four cases presented with pain. The involved bones were calcaneus in two cases, tibia in one case and ilium in one case, respectively. In all cases plain x-ray film revealed well-defined lytic lesion. Their size ranged 2 to 4.5 cm (mean size: 3.5 cm). Histologic examination showed mature adipose tissue. Three cases showed secondary changes such as atrophic bone, fat necrosis, fibrosis, dystrophic calcification, and reactive ischemic bone formation. The clinicopathologic and roentgenographic correlation are necessary in establishing correct diagnosis of this tumor.

PURPOSE: To compare the dacryocystographic results before and after silicone tube intubation in partial nasolacrimal duct obstruction. METHODS: Dacryocystography was performed on 33 eyes of 17 patients diagnosed with partial nasolacrimal duct obstruction. The anteroposterior (AP) diameters and the mediolateral diameters of the nasolacrimal ducts intubated at the operation were measured by dacryocystography, before the operation and after silicone tube removal. RESULTS: The mean AP, mediolateral diameter and length of nasolacrimal duct in the group who demonstrated improvement after the operation was 2.32 mm, 1.39 mm, and 17.14 mm before the operation, and 2.40 mm, 1.77 mm, and 17.38 mm after the operation, respectively. The mean AP, mediolateral diameter and length of nasolacrimal duct in the group who demonstrated no symptomatic improvement was 2.06 mm, 1.28 mm, and 17.42 mm before the operation, and 2.75 mm, 1.99 mm, and 18.03 mm after the operation, respectively. The alteration of the nasolacrimal duct size in the group with successful postoperative results compared with unsuccessful postoperative results showed no significant difference. CONCLUSIONS: The nasolacrimal duct showed expansion in size based on dacryocystographic results after silicone tube intubation in partial nasolacrimal duct obstruction. However, the operation results and the alteration of the nasolacrimal duct size based on dacryocystographic results demonstrated no accordance.

PURPOSE: Bowel distention stimulates neuroreceptors inside bowel wall with resultant effect to the bladder activity via segmental spinal reflex. This work aimed to elucidate the effects of distal colon and rectum distension on the micturition reflex. MATERIALS AND METHODS: The experiments were performed on female Sprague Dawley rats anesthetized with intraperitoneal urethane (1.25g/kg), weighing 250-350g. Intravesical pressure was measured by a conventional pressure transducer. Isovolumetric bladder contractions were recorded during distension of the distal colon and rectum. The frequency of voiding contractions was calculated by counting the number of peaks/10mins. of observation and the mean amplitude of the contractions were recorded from the cystometrogram. During maximal distention of the bowel, changes of the micturition reflex were observed repeatedly after injection of acetylcholine, phenylephrine and adenosine triphosphate (ATP). RESULTS: The frequency and amplitude of micturition reflex decreased significantly compared to baseline during incremental distension of the rectum. whereas, frequency was increased and amplitude was decreased significantly during distension of the distal colon. The micturition reflex inhibited by distension of the rectum was restored by acetylcholine. CONCLUSIONS: The micturition reflex was inhibited by distension of the rectum and restored by acetylcholine. This result indicated that the inhibition of the micturition reflex caused by distension of the rectum is related to parasympathetic nerve activity. With this results, it may be suggested that the constipation or abdominal distension due to intestinal motility disorder are associated with voiding dysfunction clinically.

PURPOSE: The symptoms of female urethral syndrome (FUS) can originate from mechanical or functional obstructions of the bladder neck or urethra. From retrospective reviews of women referred for evaluation of lower urinary tract symptoms (LUTS), 2.7 to 23% had urodynamic evidence of a bladder outlet obstruction (BOO). However, few urodynamic studies (UDS) have been performed on the prevalence of BOO in FUS. This study was aimed at identifying the causative factors of FUS symptoms, including BOO, as evidenced by UDS. MATERIALS AND METHODS: One hundred and sixteen women with FUS were enrolled in our UDS evaluations. An additional 247 patients, presenting for evaluation of stress urinary incontinence (SUI), served as controls. Comparisons of the maximum flow rate (Qmax), voided volume, post-void residual, detrusor pressure at maximum flow rate (PdetQmax), maximum detrusor pressure (Pdetmax) were made between the FUS and SUI cases. By definition, the FUS cases were divided into normal, BOO, detrusor under activity, detrusor instability and low compliance. These sub-groups were compared with controls in a similar way. RESULTS: Women with FUS showed a lower Qmax (15.9 versus 23.8ml/sec, p<0.05), higher post-void residual (86 versus 22ml, p<0.05), PdetQmax (24.0 versus 18.0 cmH2O, p<0.05) and Pdetmax (33.3 versus 27.9cmH2O, p<0.05) compared to those with SUI. The incidence of BOO, detrusor under activity and detrusor instability were 31.9, 25 and 16%, respectively, in the FUS group. Only 22% of women with FUS showed normal UDS findings. CONCLUSIONS: These results indicated the importance of UDS in identifying the causative factors of the symptoms of FUS. Treatment of a BOO will help provide new treatment modalities for FUS.
