Necrotizing enterocolitis (NEC) is a devastating condition of hospitalized preterm infants. Numerous studies have attempted to identify the cause of NEC by examining the immunological features associated with pathogenic microorganisms. No single organism has proven responsible for the disease; however, immunological studies are now focused on the microbiome. Recent research has investigated the numerous bacterial species residing in the body and their role in diseases in preterm infants. The timing of initial microbial colonization is a subject of interest. The microbiome appears to transfer from the mother to the newborn, as well as to the fetus. Cross-talk between the fetus and fetal microbiome takes place continuously to generate a unique immune system. This review examined the transfer of the microbiome to the human fetus, and its potential relationship with NEC.

The double eyelid operation is one of the most common cosmetic surgery performed in orientals, and there are numerous studies about surgical procedures of that. In the case of appropriate candidates, the non-incision technique makes excellent cosmetic results, with the advantages of shorter operating time, less morbidity, less pain, no scarring and easy revision of shape. But, usually the non-incision technique is recommended in the cases with thin upper eyelid, small amount of orbital fat, less redundant skin of upper eyelid and in whom a wide fold is not desired so on. Therefore, the disadvantages of this method are that it cannot be applied to all patients. The postoperative complications are disappearance or faded fold, formation of cyst or lumps, asymmetry etc. and the incidence of these complications is slightly higher than those of the incisional method. In this study, the double eyelid operation using the continuous buried suture method was performed in 210 patients for formation of double eyelid from Jan. 1993 to Dec. 1995. In conclusion very good results can be obtained by the continuous buried suture method even in the cases of puffy upper eyelid. This method can make a double eyelid shape in the fashion the patient wants and can be a new indication for correction of unilateral double eyelid. This method is safe, satisfactory and take shorter postoperative recovery time and it can reduce the incidence of postoperative complications.

PURPOSE: To evaluate the diagnostic role of a three-dimensional MR cholangiopancreatography(MRCP) over endoscopic retrograde cholangio- pancreatography(ERCP) in various extrah-epatic biliary disease. MATERIALS AND METHODS: MRCP and ERCP were performed in 45 consecutive patients with suspected extrahepatic biliary diseases. MRCP was obtained using a reverse fast imaging with a steady-state free precession (reverse FISP : PSIF) sequences, and then images were reconstructed by standard MIP algorithm. The predictability of biliary dilatation and level of obstruction of MRCP was evaluated using ERCP as a gold standard. The accuracy distinguishing malignant from benign lesions, and overall diagnostic accuracy were compared between MRCP and ERCP. RESULTS: The sensitivity, specificity and accuracy of MRCP in predicting biliary dilatation were 94.6%, 75.0% and 91.1%, respectively. The level of obstruction was accurate in 87.0% with MRCP. The sensitivity, specificity and accuracy MRCP and ERCP in distinguishing malignant from benign lesions were 76.2%, 87.5% and 82.2% and 71.4%, 83.3% and 77.8%, respectively. The overall diagnostic accuracy was 60.0% with MRCP and 55.6% with ERCP. CONCLUSION: 3D MRCP shows a good diagnostic value compared to that of ERCP, and can replace a ERCP.

Purpose: To report the short-term clinical outcomes after intrascleral fixation of intraocular lenses (IOLs) using oblique intrascleral tunnels. Methods: We retrospectively studied 17 patients (18 eyes) who underwent flanged intrascleral IOL fixation from October 2019 to October 2021. The patients were divided into those who underwent fixation using horizontal (group A) and oblique (group B) intrascleral tunnels. We compared the best-corrected visual acuities (BCVAs), cylindrical powers, refractive errors (the differences between the targeted spherical equivalents [SEs] and postoperative SEs) before and 3 months after surgery, and operating times. Results: At 3 months vs. preoperatively, there were no significant differences in BCVA (-0.83 ± 0.43 vs. -0.48 ± 0.59), refractive error (-0.06 ± 0.97 diopter [D] vs. -0.05 ± 0.80 D), cylindrical power (-0.42 ± 3.81 D vs. -0.33 ± 1.20 D), or operating time (83.33 ± 28.05 minutes [min] vs. 66.33 ± 20.57 min) between groups A and B, respectively. Conclusions In terms of the short-term clinical outcomes after use of horizontal and oblique intrascleral tunnels, we found no significant differences in any parameters studied. However, use of an oblique intrascleral tunnel may shorten the operating time.

The encapsulated hepatocellular (HCC) is a pathologic subtype of HCC. It is a well defined tumor that tends to grow slowly, and has a better prognosis than any other gross forms of HCC. Twenty surgically resected HCC were evaluated retropectively to correlate the thickness of pseudocapsules in pathology with those in computed tomography and ultrasound. At a histologic examination, pseudocapsules of seven cases were composed of two layers, an inner compact fibrous zone and outer loose fibrous zone interlaced with compressed liver parenchyma containing small vessels and newly formed bile ducts. Sonographic thickness and pathologic measurements of pseudocapsule relatively well correlated, but the former slightly overestimated the thickness of pathologic pseudocapsule (r=0.825, y=2.56x-1.23, P<0.05). On the other hand, thickness in CT and pathologic measurement did not correlate well. Thirteen cases showed one layer of pseudocapsule in which two cases were composed of thin layer of compact fibrosis and eleven cases composed of loose fibrosis. There were poor correlations in this group between thickness of pseudocapsules in pathology and those in images. Image overtly overestimated the thickness of the pseudocapsules in pathology. In conclusion, radiologic pseudocapsule of HCC may represent the compressed liver parenchyma as well as the fibrous pseudocapsule.

PURPOSE: There is no established formula for estimating renal depths in Korean. As a result, we undertook this study to develop a new formula, and to apply this formula in the calculation of glomerular filtration rate (GFR). MATERIALS AND METHODS: We measured the renal depth (RD) on the abdominal CT obtained in 300 adults (M:F=167:133, mean age 50.9 years) without known renal diseases. The RDs measured by CT were compared with the estimated RDs based on the Tonnesen and Taylor equations. New formulas were derived from the measured RDs in 200 out of 300 patients based on several variables such as sex, age, weight, and height by multiple regression analysis. The RDs estimated from the new formulas were compared with the measured RDs in the remaining 100 patients as a control. In 48 patients who underwent Tc-99m DTPA renal scintigraphy, GFR was measured with three equations (new formula, Tonnesen and Taylor equations), respectively, and compared with each other. RESULTS: The mean values of the RDs measured from CT were 6.9 cm for right kidney of the men (MRK), 6.7 cm for left kidney of the men (MLK), 6.7 cm for right kidney of the women (WRK), and 6.6 cm for left kidney of the women (WLK). The RDs estimated from Tonnesen equation were shorter than the ones measured from CT significantly. The newly derived formulas were 12.813 (weight/height)+0.002 (age)+ 2.264 for MRK, 15.344 (weight/height)+0.011 (age)+0.557 for MLK, 12.936 (weight/height)+ 0.014 (age)+1.462 for WRK and 13.488 (weight/height)+0.019 (age)+0.762 for WLK. The correlation coefficients of the RD measured from CT and estimated from the new formula were 0.529 in MRK, 0.729 in MLK, 0.601 in WRK, and 0.724 in WLK, respectively. The GFRs from the new formula were significantly higher than those from the Tonnesen equation significantly, which was the most similar to normal GFR values. CONCLUSION: We generated new formulas for estimating RD in Korean from the data by CT. By adopting these formulas, we expect that GFR can be measured by the Gates method accurately in Korean.
