Recurrent episode of meningitis in infants and children frequently constitute a frustrating and distressing, both in determination of course and treatment. The authors are reporting a infected case of congenital dermal sinus with dermoid cyst in the subarachnoid space of cauda equina and conus medullaris which was cured after complete removal of cyst and sinus tract.

4.Comparison of Stone Metabolic Risk Factors in Recurrent Stone Formers according to Sex and Age.
Korean Journal of Urology 2002;43(9):733-737
PURPOSE: In order to compare stone metabolic risk factors in recurrent stone formers, we researched lithogenic factors according to sex and age. MATERIALS AND METHODS: We performed stone metabolic studies on recurrent stone formers (77 men, 33 women) and grouped them according to age; under 40 (n=38), from 40 to 59 (n=56) and over 60 (n=16). We evaluated excretion rate differences of lithogenic and inhibitory constituents such as volume, sodium, uric acid, calcium, oxalate, and citrate from 24-hour urine samples, and calcium, sodium, uric acid, phosphate, potassium, and chloride from serum samples. We analyzed the incidence of stone metabolic risk factors between the age groups and the sexes. RESULTS: The most common detectable risk factor in all groups of recurrent stone formers was hypocitraturia. This finding was more remarkable in males aged under 60. The incidence of hypocitraturia was higher in males and in the younger group, whereas hypercalciuria was more frequent in the elder group. CONCLUSIONS: The most important cause of urolithiasis was hypocitraturia in recurrent stone formers, and this was apparent in males aged under 60.

The prognosis of esophageal cancer is poor and strategies for treatment depend on the tumor stage at the time of diagnosis. Surgery is the main therapeutic modality in esophageal cancer and known as the only treatment for cure. Preoperatively it is most important to assess whether the primary tumor is completely resectable or not. Previous staging modality such as CT can not clearly define the depth of invasion and lymph node metastasis of esophageal cancer which is the most important factor in assessing the possibility of curative resection. Endoscopic ultrasonography is now considered as an useful method in evaluating staging and resectability of esophageal cancer. We compared the findings of endoscopic ultrasonography with pathology result to evaluate the accuracy of this new technique in staging of esophageal cancer in 4 esophageal cancer patients who received surgery among the 23 patients assessed by endoscopic ultrasonography due to esophageal cancer, The depth of invasion, lymph node metastasis, and staging was correct in 3 among 4 patients. We consider endoscopic ultrasonography is an useful technique in staging of esophageal cancer.

BACKGROUND AND OBJECTIVES: Nitric oxide has been suggested to play an important role in the pathogenesis of cisplatin ototoxicity. L-NAME (NG-Nitroarginine Methyl Ester) is an inhibitor of nitric oxide synthase. MK-801 (Dizocilpine Maleate) is a NMDA receptor antagonist. To evaluate a role of nitric oxide in cisplatin ototoxicity, we investigated whether L-NAME and MK-801 can block the cisplatin ototoxicity in guinea pigs. MATERIALS AND METHOD: In the Group 1, normal saline was injected intraperitoneally as a control group. Group 2, 3, 4, and 5 were injected intraperitoneally as described in the following: Group 2, cisplatin only; Group 3, L-NAME+isplatin; Group 4, MK-801+cisplatin; Group 5, L-NAME+K-801+cisplatin. Using an auditory brainstem response, hearing threshold was tested before cisplatin administration and 5 days after cisplatin injection in each group. The morphological changes of the cochlea were observed by scanning electron microscopy. RESULTS: In the Group 2, a significant hearing loss was observed comparing to Group 1. In contrast , Group 3, 4, and 5 did not demonstrate any significant hearing loss compared to Group 1. In the scanning electron microscopy, the Group 2 showed distorsion and loss of stereocilia of the hair cells. However, the Group 1, 3, 4, and 5 demonstrated well preserved cochlear hair cell morphology. CONCLUSION: Hearing loss induced by ototoxicity of cisplatin was prevented by L-NAME and MK-801. This study suggests that NO may mediate cisplatin ototoxicity.

This study was performed to evaluate the effect of hydrogen peroxide-producing Lactobacillus acidophilus V-2Oonthe replication of periodontal pathogens, Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis. When A. actinomycetemcomitam and P. gingivalis were incubated alone and in the combination with L. acidophilus V-20, the viable cell numbers of A. actinomycetemcomitans and P. gingivalis were compared between those cultures. The effect of S. mutans, E. durans, and L. lactis on the replication of A. actinomycetemcomitans and P. gingivalis was also evaluated. The change of periodontal indexes(probine depth, gingival index, GCF volume) and the viable cell numbers of A. actinomycetemcomitans and black pigmented bdcteroides in subgingival plaque sample were evaluated following gargling of fermented milk made from L. acidophilus V-20 for 1 month on patients with periodontal disease in maintenance phase. In the mixed culture of L. acidophilus V-20 and A. actinomycetemcomitans or P. gingivalis, the replication of A. adinomycetemcomitam or P. gingivalis was completely inhibited. But in the mixed culture of P. gingivalis and hydrogen peroxide-nonproducing Lactobacillus casei, the viable cell numbers of P. gingivalis was not decreased when compared with the numbers in the mixed culture of P. gingivalis and L. acidophilus V-20. In the mixed culture of A. actinomycetemcomitam and S. mutans, E. durans, or L. lactis, the viable cell number of A. adinomycetemcomitans was not almost changed when compared with the numbers in the culture of A. actinomycetemcomitans alone. And in the mixed culture of P. gingivalis and E. durans or L. lactis, the viable cell numbers of P. gingivalis was not almost changed compared with the counts in the culture of P. gingivalis alone. But the replication of P. gingivalis was completely inhibited in the mixed culture of P. gingivalis and S. mutans. When the change of periodontal indexes following gargling of fermented milk was compared with baseline, probing depth and gingival index were not changed, but GCF volume was significantly dcreased(p (0.05). And when the viable cell numbers of microorganisms in subgingival plaque sample were compared with baseline, total viable cell number was almost unchanged and the viable cell numbers of A. actinomycetemcomitans and black pigmented bdcteroides were significantly decreased(p<0.05). These results suggest that L. acidophilus V-20 inhibit the replication of A. actinomycetemcomitans and black pigmented bacteroides by the formation of hydrogen peroxide.
