PURPOSE: The intraumbilical incision is being used more frequently, with increasing cases of single incision laparoscopic surgery. Since the umbilicus is deeper than the surrounding wall, it has abundant bacteria. No study has compared the adverse outcomes of periumbilical and intraumbilical incisions. We analyzed the wound complication rates of perforated appendicitis patients according to the types of umbilical incision. METHODS: A retrospective review was done of 280 patients with perforated appendicitis. One hundred fifty nine patients were treated with the intraumbilical incision, and 121 patients were treated with the periumbilical incision. We compared the perioperative outcomes according to each laparoscopic incision. RESULTS: There was no difference in operation time, postoperative hospital stay and analgesic requirement between the two groups. One case in the intraumbilical group (0.6%) and three cases in the periumbilical group (2.5%) developed wound infections. The umbilical complication rate showed no difference. CONCLUSION: The wound complication rate of intraumbilical and periumbilical incisions are not different. Although this retrospective study has inherent limitations, the intraumbilical incision seems to be a safe and feasible alternative for the periumbilical incision that can be easier to perform, with better cosmetic results.

PURPOSE: To analyze the recovery course of foveal microstructures and evaluate the important structures for visual improvement after vitrectomy for full thickness macular hole (MH) using optical coherence tomography (OCT). METHODS: We retrospectively reviewed the medical records of 34 cases with idiopathic macular hole. We investigated the healing process of foveal microstructures and visual acuity pre- and post-operatively at 1, 3, 6, 12 months after surgery. We evaluated the integrity of four factors by OCT image: existence of MH (Hole, H(1,3,6,12)), recovery of outer nuclear layer (ONL, O(1,3,6,12)), recovery of external limiting membrane (ELM, E(1,3,6,12)), and recovery of inner segment-outer segment (IS/OS) line of the photoreceptor (Photoreceptor, P(1,3,6,12)). We compared the recovery course and visual acuity of the four groups based on postoperative 12 months. RESULTS: The mean observed period was 1.85 ± 2.59 months at recovery of ONL, 3.78 ± 3.83 months at recovery of ONL and ELM, and 7.40 ± 3.56 months at recovery of ONL, ELM and IS/OS line. At postoperative 12 months, the best corrected visual acuity (BCVA) of Groups E and P were better than that of Groups H and O (p < 0.05). Except for group H, all groups had improved BCVA at postoperative 12 months compared to preoperative BCVA (p < 0.05). CONCLUSIONS: Recovery sequences of foveal microstructures were ONL, ELM and IS/OS line after vitrectomy for idiopathic MH. The most important structures for visual acuity were restorations of both ELM and IS/OS line.

PURPOSE: To analyze the anatomical characteristics on spectral-domain optical coherence tomography (SD-OCT) of patients who are legally blind (less than 20/1,000) due to end-stage exudative age-related macular degeneration (AMD) that does not require intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection. METHODS: After anti-VEGF injections (active group), 120 eyes of 103 exudative AMD patients experienced visual acuity improved by at least 2 lines or improvement on SD-OCT. In addition, 55 eyes of 54 end-stage exudative AMD patients who did not respond to treatment or who were legally blind due to foveal scar at the first visit (end-stage group) were evaluated retrospectively. Changes in retinal structures of the 2 groups were analyzed by SD-OCT at the last visit. RESULTS: The mean age of the end-stage group was about 5 years older than the active group. During the follow-up period, subretinal hemorrhage, intraretinal hemorrhage and retinal pigment epithelium tear occurred more frequently in the end-stage group than in the active group (p < 0.05). Intra-retinal fluids and subretinal fluids were more frequently administered in the active group than in the end-stage group, and thick subretinal hyper-reflective materials (SRHRM), fibrovascular pigment epithelial detachment (PED) and extensive inner segment/outer segment (IS/OS) line disruption were observed in all eyes of the end-stage group. The size and thickness of PED, foveal thickness and SRHRM thickness were significantly larger in the end-stage group than in the active group (p < 0.05). Disciform retinal scars were eventually formed in most of the end-stage group. CONCLUSIONS: In end-stage exudative AMD, the presence of retinal hemorrhage and retinal pigment epithelium tear during follow-up, or the findings of thick SRHRM, fibrovascular PED, and extensive IS/OS line disruption on SD-OCT suggest weak expected effect of intravitreal anti-VEGF injection, which can act as a reference for determining the timing of treatment termination.

OBJECTIVE: To evaluate the correlation of HPV infection and E6 oncoprotein expression with carcinogenesis and prognostic role of cervical carcinoma METHODS: Paraffin embedded tissues were obtained from 35 invasive cervical carcinoma, 15 carcinoma in situ, 12 dysplasia of cervix and 20 patients with benign uterine disease as control. HPV type was determined by polymerase chain reaction using type specific primers. E6 oncoprotein expression was analyzed by immunohistochemical staining using C1P5 mouse monoclonal antibody. RESULTS: 1. The positivity of HPV type 16 PCR in invasive cervical carcinoma was 77.1% and it was significantly higher than carcinoma in situ(53.3%), cervical dysplasia(25%), and control (10%). But the positivity of HPV type 18 was not correlated between above groups. 2. The positivity of HPV type 16/18 in cervical carcinoma was not correlated to patient's age. 3. The positivity of HPV in cervical carcinoma was correlated to clinical stage of cervical carcinoma but the positivity of HPV in cervical dysplasia was not correlated to the degree of dysplasia. 4. The positivity of E6 oncoprotein expression was 77.1% in invasive cervical carcinoma, 66.7% in carcinoma in situ and 20% in control group. E6 oncoprotein was not decteted among the cases which negative was for HPV 16/18. The E6 oncoprotein expression in 35 cases of invasive cervical carcinoma was negative in 8, weakly positive in 7, positive in 12, and strong positive in 8 ases. But in 20 cases of normal control group, there was no case of strong positive or posirive E6 oncoprotein expression. 5. The E6 oncoprotein expression was significantly correlated to the clinical stage and lymph node metastasis. The incidence of lymph node metastasis increased and the stage became higher as the E6 oncoprotein expression increased. CONCLUSION: These results suggest that HPV is one of the most important factors in the carcinogenesis of cervical carcinoma and the E6 oncoprotein expression may be associated with biological aggressiveness of cervical carcinoma.

Cranial mononeuropathies, manifesting particulary as opthalmoplegia or facial palsy, are common entities in the dia-betic population. However, sequential multiple cranial neuropathies due to diabetes are much less common. It is often associated with other conditions such as a brain tumor or head trauma. A 61-year-old diabetic man presented with ptosis, opthalmoplegia, and facial palsy which were manifestations of multiple cranial neuropathies involving the left 3rd, 4th, 6th, and 7th cranial nerves throughout five weeks. The pupils were not involved. The neurologic evaluation included a CSF study and a brain MRI with MRA. None of them produced any significant results. Blink reflexes revealed evidence of a left facial nerve lesion. The blood glucose was strictly controlled and steroid therapy was administered. The ptosis of the patientanjx left eyelid improved during treatment and he was discharged after 13 days. In a follow-up examination 3 months after onset, focal neurological deficits including opthalmoplegia and facial palsy on the left side were greatly improved and barely noticeable.

Intravascular papillary endothelial hyperplasia (Masson's hemangioma) is a disease characterized by exuberant endothelial proliferation within the lumen of medium-sized veins. In 1923, Masson regarded this disease as a neoplasm inducing endothelial proliferation, however, now it is considered to be a reactive vascular proliferation following traumatic vascular stasis. The lesion has a propensity to occur in the head, neck, fingers, and trunk. Occurrence within the abdominal cavity is known to be very rare, and especially in the liver, there has been no reported case up to date. The authors have experienced intravascular papillary endothelial hyperplasia of the liver in a 69-yr-old woman, and report the case with a review of the literature.

Onion peel contains a high concentration of quercetin and other flavonoids. In this study, the potential immune-enhancing effects of an onion peel water extract (OPE) supplement were investigated by the rat forced swimming test. OPE was prepared using hot water. Thirty-six male Sprague Dawley rats were fed a pellet diet for 1 week and were then randomly divided into six groups: normal control (NC), forced swimming control (FSC), positive control (quercetin 20 mg/kg), and three groups administered 4, 20, or 100 mg/kg of OPE. Oral drug administration was conducted daily for 4 weeks. All rats, except those of NC group, were forced to swim in water and were considered exhausted when they failed to rise to the water surface to breathe within a 7-s period. Blood lymphocyte counts, immune organ weights, histopathological analysis, and serum interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, and interleukin (IL)-12 levels were determined. OPE-treated rats consumed more food and had an increased thymic cortex to medulla ratio than that observed in FSC group rats (P<0.05). The area of the white pulp in the spleens of OPE-treated group rats was increased compared with that in FSC group rats (P<0.05). Furthermore, blood lymphocyte numbers and IFN-gamma, TNF-alpha, and IL-12 concentrations were significantly higher in OPE-fed groups than in FSC group (P<0.05). These results suggest that an OPE supplement can improve the immune status by increasing the number of immune-related cells and specific cytokine levels.

Journal of the Korean Society for Vascular Surgery 2009;25(1):7-11
PURPOSE: The diameter of the abdominal aorta is an important criterion for making the diagnosis of abdominal aortic aneurysm. But the diagnostic criteria for the aortic diameters and the aneurysms are based on western people' s data, and there is scant data on this for Koreans. In this study, we measured a normal range of the abdominal aortic diameter of Korean adults and we classified the diameters according to age, gender and the body mass index (BMI). METHODS: The data is based on 496 patients (male: 281, female: 215) who had no evidence of vascular disease on abdominal multi detector computed tomography exams that were been done between October through December of year 2007 at our hospital. The abdominal aorta was measured at the smallest outer diameter of the infrarenal aorta and the upper bifurcation level. The age of the patients was from 20 to 70 years-old and the patients were divided into 6 groups by age. The patients were also divided into three groups according to their BMI (the low weight, normal weight and over weight groups). We computed the average and standard deviation of the aortic dimensions from each group. RESULTS: The average diameter at the infrarenal aorta was 18.32 mm and that at the upper bifurcation level was 17.25 mm. The males' average aortic diameter at the infrarenal aorta and at the upper bifurcation level was 19.23 mm and 18.10 mm, respectively, and those values for the females were 17.09 mm and 16.20 mm, respectively. In both the males and females, the diameter increased with increasing patient age (P<01). For the BMI, the diameter was larger for the higher BMI group. CONCLUSION: For the normal Korean population, the diameter of the abdominal aorta increases with aging and with an increased BMI, but the changes were relatively smaller as compared with the western normal range. More studies are needed to determine Koreans' normal range of the diameter of the abdominal aorta and this data can be applied to the diagnosis and treatment of abdominal aortic aneurysm.
