STUDY DESIGN: A retrospective analysis of the patients who had cauda equina syndrome caused by a herniated lumbar disc. OBJECTIVES: To assess the clinical debates concerning the diagnosis, treatment, and results of treatment. SUMMARY OF LITERATURE REVIEW: This syndrome has been considered as an absolute indication of surgical treatment in the herniated lumbar disc and poor prognosis after surgery were reported. Although there are debates on the timing of surgery, early recognition early surgical treatment are recommended for a better results of treatment. MATERIALS AND METHODS: 23 consecutive patients having a cauda equina syndrome caused by herniated lumbar disc were reviewed retrospectively. They were 14 males and 9 females having ages of 41.6 in average. The incidence of this syndrome was 3.8% of the patients who had surgical treatment of herniated lumbar disc. RESULTS: All patients had bladder dysfunction in addition to the low back pain and radicular pain in the leg, but five patient did not recognize their urinary retention which were shaded by severe leg pain. A surgical treatment were performed for all patients at 6.8 days in average after onset of the bladder dysfunction. At follow-up of 3 years and 3 months in average after surgery, 20 patients(86.9%) had satisfactory resolution of the low back pain and leg pain, and all patients had complete recovery of motor weakness except one patients who had residual foot drop. Bladder function recovered satisfactorily in 18 patients (78.3%), but 4 patients had some difficulty of urination and one patient needed a sphinterotomy for urination. CONCLUSIONS: The cauda equine syndrome in herniated lumbar disc was often not recognized early and a poor result of treatment was not rare, particularly in the patients who had acute onset and severe bladder dysfunction. So, early diagnosis and active surgical treatment are recommended for a better results of treatment.

The intestinal histopathology and in situ postures of Gymnophalloides seoi (Digenea: Gymnophallidae) were studied using C3H/HeN and C57BL/6 mice as experimental hosts; the effects of immunosuppression were also observed. The metacercariae isolated from naturally infected oysters, 300 or 1,000 in number, were infected orally to each mouse, and the mice were killed at days 3-21 post-infection (PI). In immunocompetent (IC) mice, only a small number of flukes were found in the mucosa of the duodenum and jejunum during days 3-7 PI, with their large oral suckers pinching and sucking the root of villi. The intestinal mucosa showed mild villous atrophy, crypt hyperplasia, and inflammations in the villous stroma and crypt, with remarkable goblet cell hyperplasia. These mucosal changes were almost restored after days 14-21 PI. In immunosuppressed (IS) mice, displacement as well as complete loss of villi adjacent to the flukes was frequently encountered, otherwise the histopathology was generally mild, with minimal goblet cell hyperplasia. In these mice, numerous flukes were found, and it seemed that they were actively moving and rotating in situ. Several flukes were found to have invaded into the submucosa, almost facing the serosa. These results indicate that in IC mice the intestinal histopathology caused by G. seoi is generally mild, and the flukes do not penetrate beyond the mucosa, however, in IS mice, the flukes can cause severe destruction of neighboring villi, and some of them invade into the submucosa.

A case of adenocarcinoma of cystic duct associated with GB empyema is presented. A 72 year old male was admitted to Kwangju Christian hospital because of abdominal pain in right upper quadrant for 4 days. He underwent explolaparotomy under the impression of GB empyema or GB cancer. For seeking causative factor of GB empyema, serial sections of cystic duct and mapping were performed. We can find adenocarcinoma of cystic duct in the specimen removed at cholecystectomy. The criteria for disgnosis of cystie duct carcinoma which was outlined by Farrar. These criteria are; 1) The growth must be restricted to the cystic duct, 2) There is no neoplastic process in the gall bladder, hepatic and common bile duct. 3) Histopathological examination must be comfirm carcinoma. Here we report a case of adenocarcinoma of cystic duct associated with GB empyema with brief review of Literature.

As the uses of dental implants are prevailing, the need for sinus bone graft is increasing. Deproteinized bovine bone mineral (DBBM) was not mentioned in 1996 Sinus Bone Graft because of the deficit of the available data. Since then, many clinical and laboratory reports support the use of DBBM in the sinus bone graft procedure. In this report, the histological and clinical successes of sinus bone grafting with DBBM is discussed with available literatures. After sinus bone grafts with DBBM, the proportion of new bone formed was similar or superior to natural maxillary posterior alveolar bone after healing period of 6 months to 1 year. It seems that the grafted DBBM is not be either resorbed nor replaced with bone, but this may not disturb the osseointegration of dental implants installed into it. The clinical survival rates of dental implants installed on the sinus grafted with DBBM was similar to those installed on the ungrafted posterior maxillary alveolar ridge or grafted with autogenous bone. So, it can be concluded that DBBM can be used successfully in the sinus bone graft.
