Urachal anomalies are very rare. The umbilicus and the structures which lead to its formation rarely cause trouble except in patients with an error. Embryologically, the urachus represents the vestigial remnant of the allantois which, in the fetus, communicates with the cloaca. The patent urachus results from failure of luminal closure of the urachus Herein a case of congenital patent urachus reported with a brief review of literatures.

BACKGROUND: Several automated and nonautomated systems have been developed and are commercially available for the identification of gram-negative bacilli. EASY 24E+ kit was recently developed as Korean kit for identification of gram-negative bacilli. So we evaluated the accuracy and clinical utility of EASY 24E+ compared with API 20E and VITEK GNI+. METHODS: The 221 clinical isolates of Enterobacteriaceae, including 17 C. freundii, 20 E. cloacae, 31 E. coli, 6 E. aerogenes, 29 K. pneumoniae, 3 K. oxytoca, 11 M. morganii, 13 P. mirabilis, 16 Salmonella spp., 20 S. marcescens, 9 Shigella spp., 22 S. sonnei, 16 S. typhi, 8 Y. pseudotuberculosis and 10 control strains were identified by API 20E, EASY 24E+, and VITEK GNI+. Discrepant strains were performed repeat identifications and we evaluated overall accuracy. RESULTS: All of control strains were correctly identified by three systems. The overall correct results at species level and at the genus level for 221 clinical isolates, were 96.8% and 99.1% by the VITEK GNI+, 97.7% and 97.7% by the EASY 24+ and 99.1% and 100% by the API 20E. All of Salmonella spp., S. typhi and Shigella spp. were correctly identified by all three systems and the discrepant identifications of species were 2 Y. pseudotuberculosis, 3 K. pneumoniae and 2 K. oxytoca by VITEK GNI+, 4 C. freundii and 1 P. mirabilis by EASY 24+, and 2 S. marcescens by API 20E. CONCLUSIONS: All three identification systems are accurate methods for the identification of Enterobacteriaceae, and EASY 24+ is comparable with API 20E and VITEK GNI+.

Persistent cloaca in a female newborn is one of the most complex and challenging developmental malformations. The incidence is about 10% of all anorectal anomalies. Treatment of cloacal malformations has evolved during the past 40 years; however, it still remains one of the most difficult operations. In 1997, Pe a reported that a new technical variant called "Total urogenital mobilization" We also repaired cloacal anomaly using "Total urogenital mobilization" in 3 patients. The operations were performed between age 15- and 28-month. The length of the common channels was 2.5-3.0 cm. Two cases had double vaginas and one of them also had double uterus. The operation time was 4-5 hours and no major complications occurred. A satisfactory functional and cosmetic results were obtained.

Plasmid-mediated quinolone resistance (PMQR) genes: qnr, aac(6')-Ib-cr, and qepA were investigated among 153 armA and 51 rmtB-positive transconjugants and their 204 clinical isolates of Enterobacteriaceae. Overall, qnrB4 and aac(6')-Ib-cr genes were identified in 52.3% (63 K. pneumoniae, 10 E. coli, 4 E. cloacae, and 3 E. aerogenes) and 24.8% (16 K. pneumoniae, 8 E. coli, 6 S. marcescens, 4 E. cloacae, 3 C. freundii and 1 K. oxytoca) of 153 armA-positive isolates, respectively. Four isolates of K. pneumoniae and two isolates of E. coli positive for armA co-harbored both qnrB4 and aac(6')-Ib-cr. The qepA gene was detected in 11.8% (5 E. coli and 1 K. pneumoniae) of 51 rmtB-positive clinical isolates and their transconjugants. Southern hybridization confirmed the co-localization of qepA and rmtB on a large conjugative plasmid of size between 90 to 170 kb. Inc replicon typing showed that qnrB4/6, aac(6')-Ib-cr, and qepA genes were principally disseminated by IncFIIAs, IncL/M, and IncF plasmids, respectively. This study constitutes the first report of the three known PMQR genes among the 16S rRNA methylase producing Enterobacteriaceae isolates of human origin from Korea.

6.A Cloacal Exstrophy Variant Associated with Hindgut Duplication
Journal of the Korean Association of Pediatric Surgeons 1995;1(2):190-194
Diphallus is a rare congenital anomaly and is frequently associated with duplication of the urinary tract and rectosigmoid, and commonly associated with vertebral anomalies. Remzi reported less than 100 cases of duplication of all or a portion of the penis, but about 10 cases of complete diphallus with exstrophy of cloaca was reported, and a case of complete diphallus associated with hingut duplication was reported, and complete diphallus with displacement of bladder associated hindgut duplication and imperforate anus was not reported in Korea. We experienced a case of the complete diphallus associated with displacement of bladder, hindgut duplication, and imperforate anus as a variant of cloacal exstrophy. A review of published cases suggests that this may be the first example of a complete dip hall us with displacement of bladder coexisting with the hindgut duplication and imperforate anus.

7.The embryology of persistent cloaca and urogenital sinus malformations.
Asian Journal of Andrology 2020;22(2):124-128
Cloacal malformations are characterized by the confluence of the lower urinary tract, the female reproductive tract, and the rectum to create a common channel with a single opening on the perineum. The presence of a cloaca is a normal phase of early human embryological development. Between the 4th and 7th weeks of gestation, the cloaca undergoes subdivision to form the hindgut and urogenital sinus. Failure of this process results in the congenital anomaly termed persistent cloaca (PC). The term urorectal septum malformation sequence (URSMS) is also used to describe this anomaly. The classic description of this process which is still cited in many standard textbooks dates from the 19th century. However, this has been increasingly called into question by the findings of studies using modern scientific methodology. Urogenital sinus anomalies are defined by the confluence of the urethra and vagina to form a common channel of varying length with a single perineal opening. In this condition, the anorectal canal opens separately on the perineum. The presence of a urogenital sinus represents a transient phase of the normal development of the lower genital tract in the female fetus. However, the form of urogenital sinus most commonly encountered in the developed world is a feature of disordered sexual differentiation and does not arise simply from the persistence of the anatomical structure which is a feature of normal fetal development.

Korean Journal of Urology 2006;47(3):334-340
We report here the short-term results of 3 cases of cloacal and bladder exstrophy that underwent complete primary exstrophy repair. One case was diagnosed as bladder exstrophy and the others were diagnosed as cloacal exstrophy. Complete primary exstrophy repair for all 3 cases was carried out within 24 hours after birth. There was no wound dehiscence within the follow-up period of 12 months. The complete primary exstrophy repair with positioning the bladder neck and urethra in the deep pelvic cavity achieves a satisfactory short-term result.

9.Analysis of Inpatients with Bacterial Keratitis Over a 12-Year Period: Pathogenic Organisms and Antibiotic Resistance.
Journal of the Korean Ophthalmological Society 2012;53(3):372-384
PURPOSE: To investigate the distribution of bacterial keratitis isolates and the shifting trends of in vitro antibiotic susceptibility of the isolates for inpatients with bacterial keratitis. METHODS: Three hundred ninety-two bacterial isolates with 366 positive culture cases from consecutive corneal scrapes of 988 clinically diagnosed bacterial keratitis inpatients hospitalized at Yeungnam University Hospital between January 1998 and December 2009 were retrospectively reviewed. The bacteriological profiles and in vitro resistance were evaluated in the first and second six-year periods. RESULTS: The percentage of positive cultures was 37.0% (366/988). The commonly isolated Gram-positive and Gram-negative organisms were S. epidermidis (98; 25.0%) and P. aeruginosa (41; 10.5%), respectively. The ratio of Gram-positive to Gram-negative isolates was 1.24:1. The Gram-positive isolates significantly decreased compared to the Gram-negative isolates in the last six-year period (45.3% versus 54.7%, respectively) relative to those in the first six-year period (66.1% versus 33.9%, respectively). S. epidermidis and S. aureus decreased, and E. cloacae, S. marcescens, and S. maltophilia increased in the last six-year period. The resistance of fluoroquinolone to the Gram-positive isolates, though not statistically significant, tended to increase to 34.1% from 21.5% (p=0.061), and the methicillin-resistant S. aureus tended to increase to 54.2% from 30.0% (p=0.055). CONCLUSIONS: S. epidermidis and P. aeruginosa were the most common bacterial keratitis isolates in Gram-positive and Gram-negative isolates. The Gram-positive isolates tended to decrease, though the Gram-negative organisms tended to increase in the last six-year period compared to the first six-year period. Empirical antibiotic selection should be based on local susceptibility patterns and distribution of bacterial isolates.

Korean Journal of Clinical Pathology 1998;18(2):161-167
BACKGROUND: One of major consideration of any identification (ID) system is the cost. Commercial kits, however, are too expensive. The aim of this study was to evaluate the clinical usefulness of the computerized ID system based on the conventional minimal biochemical tests for the identification of clinical isolates of Enterobacteriaceae. METHODS: During June 1996 to April 1997, Enterobacteriaceae were tested by triple sugar iron, motility, indole, ornithine decarboxylase, and citrate, and 2-4 biochemical tests were tested additionally according to the characteristics of colony on MacConkey agar. We also compared the conventional ID system with API Rapid 32E (ATB system, bioMrieux, France) to determine the accuracy of conventional ID system. RESULTS: Among the 3,652 strains of Enterobacteriaceae, 84.4% were identified by conventional tests. The identification rate of Enterobacteriaceae by conventional tests; K. pneumoniae, E. coli, P. stuartii, M. morganii, and P. mirabilis were more than 80%; K. oxytoca, Enterobacter, and S. marcescens were ranged from 70% to 80%; P. vulgaris, P. rettgeri, and C. freundii were less than 70%. Among the 133 isolates tested simultaneously by two ID systems, each of one strain of M. morganii, E. cloacae, and S. marcescens on conventional minimal biochemical tests were identified as E. coli, E. sakazakii, and S. liquefaciens by commercial kit. CONCLUSIONS: Our computerized ID system based on the minimal biochemical tests was found to offer simple, reliable and economic in the identification of clinical isolates of Enterobacteriaceae. And further studies are needed for the improvement of accuracy and identification rate.
