Abstract
OBJECTIVE To investigate the prognostic significance of L1 cell-adhesion molecule (L1CAM), β-catenin, and programmed death-ligand 1 (PD-L1) in endometrial cancer (EC) patients, with a focus on p53 wild-type subgroup, for additional risk stratification. METHODS This retrospective cohort study included EC patients classified according to Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE) who underwent primary surgical treatment at the single center between January 2014 and December 2018. Immunohistochemical staining was performed for four mismatch repair (MMR) proteins, p53, L1CAM, β-catenin, and PD-L1. DNA polymerase epsilon (POLE) mutation was detected by hot spot sequencing via droplet digital polymerase chain reaction. Survival outcome of each subgroup of L1CAM, β-catenin, and PD-L1 was measured according to their expression. RESULTS A total of 162 EC patients were included. Endometrioid histologic type and early-stage disease were 140 (86.4%) and 109 (67.3%), respectively. ProMisE classification assigned 48 (29.6%), 16 (9.9%), 72 (44.4%), and 26 (16.0%) patients to MMR-deficient, POLE-mutated, p53 wild-type, and p53 abnormal subgroups, respectively. L1CAM was identified as an independent poor prognostic factor for progression-free survival (PFS; adjusted hazard ratio [aHR], 3.207; 95% confidence interval (CI), 1.432-7.187; P = 0.005), whereas β-catenin and PD-L1 positivity were not associated with recurrence (P = 0.462 and P = 0.152, respectively). In p53 wild-type subgroup, L1CAM positivity was associated with worse PFS (aHR, 4.906; 95% CI, 1.685-14.287; P = 0.004). CONCLUSION L1CAM positivity was associated with poor prognosis in EC and further stratified the risk of recurrence in p53 wild-type subgroup, whereas β-catenin and PD-L1 were not informative for risk stratification.

Abstract
OBJECTIVE Previously, we suggested that patients with cervical cancer (CC) with tumors ≤2 cm on preoperative magnetic resonance imaging (MRI) are safe candidates for laparoscopic radical hysterectomy (LRH). Here, we aim to investigate whether LRH deteriorates the prognosis of patients with incidentally identified high-risk factors; lymph node metastasis (LNM) or parametrial invasion (PMI). METHODS We identified patients with 2009 FIGO stage IB1 CC who underwent Type C LRH or open radical hysterectomy (ORH) at three tertiary hospitals between 2000 and 2019. Those with a tumor ≤2 cm on preoperative MRI who were not suspicious of LNM or PMI preoperatively were included, while those who were indicated to receive adjuvant treatment but did not actually receive it were excluded. Survival outcomes were compared between the LRH and ORH groups in the overall population, then narrowed down to those with LNM, and then to those with PMI. RESULTS In total, 498 patients were included: 299 in the LRH group and 199 in the ORH group. The LRH and ORH groups showed similar 3-year progression-free survival (PFS) (94.0% vs. 93.6%; P = 0.615) and 5-year overall survival (OS) rates (97.2% vs. 96.8%; P = 0.439). On pathologic examination, 49 (9.8%) and 16 (3.2%) patients had LNM and PMI, respectively, and 10 (2.0%) had both. In the LNM subgroup, 5-year PFS rate was not significantly different between the LRH and ORH groups (73.2% vs. 91.7%; P = 0.169). In the PMI subgroup, no difference in PFS was observed between the two groups (P = 0.893). CONCLUSIONS LRH might not deteriorate recurrence and mortality rates in CC patients with tumors ≤2 cm when adjuvant treatment is appropriately administered, even if pathologic LNM and PMI are incidentally identified.

Abstract
OBJECTIVE To determine the clinical significance of systematic lymph node dissection (LND) and to better define the relevant extent of LND in intermediate- to high-risk early stage endometrial cancer (EC). METHODS Patients who received surgery as a primary treatment of histologically confirmed EC and preoperatively considered as uterus-confined early stage disease were included in the study population. The rates of lymph node metastasis (LNM) according to the risk groups and anatomic sites were assessed. Univariate and multivariate analyses were performed to evaluate risk factors for recurrence. RESULTS A total of 804 patients were included in the study analysis. The rates of LNM were significantly different according to the risk group; 1.2% in low-risk, 20.1% in intermediate-risk, and 30.0% in high-risk group. When assessing the rates of LNM in individual anatomic sites, positive LNs were evenly distributed throughout the pelvic and para-aortic regions. In the intermediate to high-risk EC cases, the rates of para-aortic LNM below and above inferior mesenteric artery (IMA) were 11.1% and 12.5%, respectively. On multivariate analysis, LNM was the only independent risk factor for recurrence in the intermediate to high-risk EC (hazard ratio=2.63, 95% confidence interval=1.01-6.82, p=0.047). CONCLUSION LNM was frequently observed in intermediate- and high-risk early stage EC and it served as an independent risk factor for recurrence. When considering the similar rates of LNM between below and above IMA, nodal assessment needs to be performed up to the infra-renal level, especially for the staging purpose in high-risk EC.

Abstract
OBJECTIVE To assess the outcomes of retreatment using progestin for recurrence after a complete response with fertility-sparing treatment in patients with early endometrial cancer. METHODS We retrospectively reviewed the data of patients with presumed stage IA, grade 1 endometrioid endometrial cancer who developed intra-uterine recurrence after a complete response with fertility-sparing treatment using progestin. Oncological and pregnancy outcomes were analyzed after repeated fertility-sparing treatment. Logistic and Cox regression analyses were performed to analyze the prognostic factors associated with a complete response with secondary fertility-sparing treatment and recurrence-free survival after secondary fertility-sparing treatment, respectively. RESULTS Fifty patients with a median age of 31 years (range 23-40) underwent secondary fertility-sparing treatment. With a median secondary progestin treatment duration of 9 months (range 3-55), the complete response rate was 78% (39/50) and no patients had extra-uterine spread of disease. Among the 26 (67%) patients who attempted to conceive after complete response, 10 became pregnant (3 spontaneous abortions, 7 live births). Eighteen (46.1%) patients had a second recurrence, with a median recurrence-free survival after secondary fertility-sparing treatment of 14 months (range 3-36); 15 patients received tertiary fertility-sparing treatment and nine (60%) achieved a complete response. Polycystic ovary on ultrasound (OR 5.82, 95% CI 1.1 to 30.6, p=0.037) was associated with an increased complete response rate with secondary fertility-sparing treatment. Multivariable analysis revealed that recurrence-free survival after initial hormonal treatment >6 months (HR 0.11, 95% CI 0.02 to 0.51, p=0.005) and pregnancy after secondary fertility-sparing treatment (HR 0.27, 95% CI 0.08 to 0.98; p=0.047) were significantly associated with longer recurrence-free survival after secondary fertility-sparing treatment. CONCLUSIONS Repeated progestin treatment was associated with a 78% response rate and it was safe in patients with intra-uterine recurrent endometrial cancer. Thus, it might help preserve fertility after first and second recurrences.

Abstract
OBJECTIVE To compare the effects of minimally invasive surgery (MIS) and open surgery (OPS) on the risk of recurrence and mortality in patients with endometrial cancer (EC) of high-risk histology (grade 3 endometrioid adenocarcinoma, papillary serous carcinoma [PS], clear cell carcinoma [CC], and carcinosarcoma) using meta-analysis. MATERIAL AND METHODS We systematically reviewed published studies comparing MIS and OPS in EC patients with high-risk histology until January 2022. The endpoints were recurrence and mortality rate. Study design features that may have affected participant selection, recurrence/death detection, and manuscript publication were assessed. For pooled estimates of the effect of MIS on recurrence/mortality, the random- or fixed-effects meta-analytical models were used after assessing the cross-study heterogeneity. RESULT Nine observational studies (eight retrospective and one prospective) fulfilled our search criteria (MIS, 8877 patients; OPS, 5751 patients). The fixed-effects model-based meta-analysis indicated that MIS did not significantly increase the risk of recurrence (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.71-1.05; p = 0.13) and mortality (HR, 0.86; 95% CI, 0.79-0.93; p < 0.001) when compared with OPS. This pattern was also observed in the subgroup analyses based on the stage (early stage vs. all stage), histology (PS and CC), and MIS type (laparoscopy vs. robotic). There was no evidence of publication bias. CONCLUSION This meta-analysis of observational studies revealed that MIS did not compromise the prognosis of EC patients with high-risk histology. Well-designed randomized controlled trials could verify the results of this uncommon but deadly tumor.

Abstract
This study aimed to determine whether endocervical glandular involvement (GI) affects the clinical prognosis of patients with cervical intraepithelial neoplasia (CIN) III who underwent the loop electrosurgical excision procedure (LEEP). This retrospective study included 250 patients who underwent LEEP for the treatment of CIN III between August 2005 and May 2020. The medical records of 234 patients were analyzed; 137 (58.5%) patients were GI negative, and 97 (41.5%) were GI positive. Margin involvement of the LEEP specimen was found in 59 (45.4%) patients in the GI-negative group and 54 (58.7%) patients in the GI-positive group (p = 0.051). The additional surgical procedures (repeat conization or hysterectomy) were significantly more performed in GI-positive patients than in GI-negative patients (40.9% vs. 23.1%, p = 0.004). When comparing the LEEP specimens of GI-1 (GI-positive confirmed via cervical biopsy before conization) and GI-2 (GI-positive confirmed via conization), we found that the mean depth was significantly greater in the GI-1 group (10.9 mm) than in the GI-2 group (7.6 mm) (p = 0.024). Surgical margin involvement was more frequently observed in the GI-2 group than in the GI-1 group (p = 0.030). There was no significant difference in the recurrence rates of CIN between the GI-negative and GI-positive groups (p = 0.641). In conclusion, despite no significant differences in residual disease and CIN recurrence between the GI-negative and GI-positive groups, additional surgical treatments were more frequently performed in GI-positive patients. Repeat surgery based on GI positivity should be carefully considered to avoid overtreatment and surgical complications.

Abstract
This study compared survival outcomes for patients with stage IB1 to IIA2 (International Federation of Gynecology and Obstetrics stage 2009) cervical cancer who underwent open radical hysterectomy (ORH) versus those who underwent minimally invasive radical hysterectomy (MIRH) using vaginal colpotomy (VC).Data for 550 patients who were diagnosed with cervical cancer at our institution during the period August 2005 to September 2018 was retrospectively reviewed. Of these, 116 patients who underwent radical hysterectomy (RH) were selected after applying the exclusion criteria. All MIRH patients underwent VC. Clinicopathological characteristics and survival outcomes between the ORH and MIRH groups were compared using appropriate statistical testing.Ninety one patients were treated with ORH and 25 with MIRH during the study period. Among the MIRH patients, 18 underwent laparoscopy-assisted radical vaginal hysterectomy and 7 underwent laparoscopic RH. Preoperative conization was performed more frequently in MIRH patients than in ORH patients (44% vs 22%, respectively, P = .028). The incidence of lymph node invasion was higher in the ORH group than in MIRH group (37.4% vs 12.0% respectively; P = .016). Following RH, ORH patients underwent adjuvant treatment more frequently than MIRH patients (71.4% vs 56.0%, respectively, P = .002). There were no significant differences between ORH and MIRH patients for either progression-free survival (PFS) (91.3% vs 78.7%, respectively; P = .220) or 5-year overall survival (OS) (96.6% vs 94.7%, respectively, P = .929). In univariate analysis, lympho-vascular space invasion was the only clinicopathological feature associated with decreased PFS. No other clinicopathological factors was significantly associated with PFS or OS in univariate and multivariate analyses.Despite a higher incidence of unfavorable prognostic factors in ORH patients, their survival outcomes were not different to those of MIRH patients with VC.

Abstract
Objectives: Syndecan-1 (SDC-1), a transmembrane heparin sulphate proteoglycan predominantly expressed on epithelial cells, also exists in a soluble form through ectodomain shedding. SDC-1 expression and shedding may be modulated in the inflammatory milieu of primary Sjögren's syndrome (SS). We investigated SDC-1 expression in minor salivary glands (MSGs) and analysed the association between salivary or plasma levels of SDC-1 and clinical parameters in SS.Method: We measured salivary and plasma SDC-1 levels via an enzyme-linked immunosorbent assay and assessed the salivary flow rates (SFRs) in 70 patients with SS and 35 healthy subjects. Disease activity indices, serological markers, salivary gland scintigraphy, and MSG biopsy were evaluated in patients with SS.Results: SDC-1 expression was upregulated on ductal epithelial cells in inflamed salivary glands. Salivary SDC-1 levels in patients significantly exceeded those in healthy subjects [median (interquartile range) 49.0 (20.7-79.1) vs 3.7 (1.7-6.3) ng/mL, p < 0.001] and inversely correlated with SFRs (r = -0.358, p = 0.032) and ejection fractions of the parotid (r = -0.363, p = 0.027) and submandibular (r = -0.485, p = 0.002) glands in salivary gland scintigraphy. Plasma SDC-1 levels were significantly correlated with the EULAR Sjögren's Syndrome Disease Activity Index (r = 0.507, p < 0.001) and EULAR Sjögren's Syndrome Patient Reported Index (r = 0.267, p = 0.033). Focus scores were correlated with salivary SDC-1 levels (r = 0.551, p = 0.004).Conclusion: Salivary and plasma SDC-1 levels may constitute potential biomarkers for salivary gland function and disease activity, respectively, in SS.

Abstract
Objective This study was performed to evaluate the significance of positive resection margins (RMs) with the loop electrosurgical excision procedure combined with cold coagulation (LEEP with CC) as a definitive treatment for patients with cervical intraepithelial neoplasia (CIN) and adenocarcinoma in-situ. Methods We retrospectively reviewed 467 patients who underwent LEEP with CC. A right-angled triangular loop in a single pass followed by a CC (120 °C) to the cone bed for 10 to 20 s was used. Pathology reports and clinical data were obtained and evaluated. Results Histopathology evaluation of LEEP tissue samples revealed the presence of CIN 1 in 69, CIN 2/3 in 366, AIS in 5 and invasive carcinoma in 16 (microinvasive squamous cell carcinoma (SCC) and invasive SCC, 13 and 3) patients. Margins were positive in 66 (14.5%) cases: 0 in CIN 1, 54 in CIN 2/3 (12.4%), 1 in AIS (20.0%) and 11 in microinvasive/invasive SCC (68.8%). Although 54 CIN2/3 patients with positive RMs did not undergo additional treatment, 1 of these (1.9%) was confirmed to have residual CIN3 at the first follow-up. Two of 8 (25.0%) microinvasive SCC patients with positive RMs were confirmed to have residual diseases (1 microinvasive SCC and 1 invasive SCC) after hysterectomy. Four out of 360 (1 positive RM, 3 negative RM) CIN cases recurred during the study period. Conclusions These results suggest that CIN patients with positive RMs after LEEP with CC may be followed up without additional treatment.

Abstract
Esophageal carcinoids are exceedingly rare and only a few limited cases have been reported. Because knowledge about esophageal carcinoid is based primarily on case reports, the treatment of choice has not been settled. We report here on a localized carcinoid tumor in the esophagogastric junction. As our initial biopsy was nearly equal for the excision, we only performed coagulation ablation therapy instead of a wide excision which is traditionally recommended. The patient is free of recurrence so far during 50-month follow-up. Our report suggests that esophageal carcinoids may be not particularly associated with a poor prognosis.

Abstract
In this study, we identified a new tobamovirus from diseased Aporcactus flagelliformis cactus plants, named it rattail cactus necrosis-associated virus (RCNaV), and determined its complete genome sequence. The full RCNaV genome consisted of 6,506 nucleotides and contained four open reading frames coding for proteins of M(r) 128 kDa (3,441 nt), 185 kDa (4,929 nt), 55 kDa (1452 nt), 36 kDa (1,005 nt) and 19 kDa (513 nt) from the 5' to 3' end, respectively. The overall similarities for the four ORFs of RCNaV were from 32.5% to 64.1% and from 17.0% to 67.3% to those of the other tobamoviruses, at the nucleotide and amino acid level, respectively. Comparison of the coding and non-coding regions of the virus with those of other tobamoviruses showed that RCNaV is the most closely related to cactus mild mottle virus.

Abstract
BACKGROUND/AIMS Although studies using optical coherence tomography (OCT) reported that the retinal nerve fibre layer (RNFL) thickness of myopic eyes was thinner than those of normal controls, it was unclear if this finding indicated the difference in actual structural thickness or that created by sources affecting accuracy of OCT measurement. This study's aim was to evaluate the effect of refraction power on the measurement of the RNFL thickness using spectral-domain OCT. METHODS OCT scans to measure RNFL thickness were repeated in 15 cycloplegic eyes of 15 participants, while different refraction powers were induced by wearing soft contact lenses of eight different dioptres (-6 to +8). RESULTS Measured RNFL thicknesses decreased significantly with soft contact lenses of higher plus dioptres and increased with those of more minus dioptres. This finding was consistent with or without controlling factors including the signal strength and test-retest variability of the machine. Measurement of peripapillary RNFL thicknesses was not varied between scans performed with and without plano contact lenses. CONCLUSIONS In spectral-domain OCT, RNFL thickness was underestimated in eyes with increasing negative refraction power and overestimated with increasing positive refraction power.

Abstract
AIM To identify optical coherence tomography (OCT) patterns predictive of visual outcome in diabetic macular oedema (DMO) patients who undergo focal laser photocoagulation. METHODS This study involved 70 eyes (45 patients) with clinically significant macular oedema that underwent focal laser photocoagulation using the Early Treatment Diabetic Retinopathy Study protocol. Preoperative macular OCT images were retrospectively examined. OCT features were classified into four patterns: diffuse retinal thickening (DRT); cystoid macular oedema (CMO), serous retinal detachment and vitreomacular interface abnormalities (VMIA). Changes in retinal thickness, retinal volume and visual acuity (VA) after focal laser photocoagulation were evaluated and compared with respect to their OCT features. RESULTS After focal laser photocoagulation, changes in retinal thickness and retinal volume were significantly different for different OCT types (p = 0.002 and p<0.001). The change in VA from baseline was not significantly different between groups (p = 0.613). The DRT pattern was associated with a greater reduction in retinal thickening and better VA improvement than the CMO or VMIA patterns. Proportions of patients with persistent DMO (central macular thickness >250 microm after laser treatment) were greater for the CMO and VMIA patterns than DRT pattern. CONCLUSION DRT patients achieved a greater reduction in retinal thickening and greater VA increases than CMO and VMIA patients. We suggest that classifying DMO structural patterns using OCT might allow visual outcome to be predicted after laser photocoagulation.

Abstract
This study of larval Drosophila melanogaster examined the effects of injecting the prototypical organic cation tetraethylammonium (TEA) into the hemocoel or adding TEA and/or other organic cations to the diet. Mortality, hemolymph TEA levels, and Malpighian tubule TEA secretion rates were measured. The LD50 for dietary TEA was 158.4 mM and mortality increased if competitive inhibitors of organic cation transporters were also included in the diet. Mortality increased from 24% on TEA (100 mM) alone to 83 and 67% when the diet contained both TEA and quinidine (10 mM) or cimetidine (100 mM), respectively. TEA-selective microelectrode measurements indicated that hemolymph TEA concentration was approximately 3% of that in the diet for larvae maintained on TEA-enriched diet for 24 h. Malpighian tubules isolated from larvae exposed to dietary TEA excreted more TEA than did tubules from controls fed a TEA-free diet. However, the rate of decline of hemolymph TEA concentration following ingestion or injection of TEA into the hemocoel was greater than that explicable by rates of active transport by the gut and Malpighian tubules (MTs). We propose that TEA concentrations in the hemolymph are reduced not only by active transport across the MTs and gut, but also by diffusion into the gut. The latter pathway is particularly important when larvae previously maintained upon TEA-enriched diet are transferred to a TEA-free diet. The ingestion of TEA-free food not only clears the gut lumen, but also creates a TEA-free compartment into which TEA may passively diffuse from the hemolymph.

Abstract
Sclerosing meningioma is a rare morphologic subtype of meningioma and may be mistaken for atypical or malignant meningioma and astrocytoma or schwannoma because of marked collagen deposits and a sparse population of cells with little resemblance to meningothelial cells. Authors describe the histopathologic and immunophenotypic features of five cases of sclerosing meningioma. Histologically, all the cases consisted of paucicellular collagenous tissue containing spindle cells with or without small foci of meningothelial cell proliferation. The morphology and immunohistochemical profile of the spindle cells were different from those of conventional meningothelial cells. The meningothelial cells showed a typical immunoreactivity of conventional meningiomas, while the spindle cells displayed a strong expression of vimentin. The Ki-67 labelling index was uniformly low in all cases, and none of cases expressed p53 protein. In summary, the recognition of meningothelial cells in massively sclerotic lesions is helpful for a correct diagnosis. In the cases with a total absence of meningothelial cells, however, the vague collagenous whorls are more diagnostic rather than immunohistochemistry. Considering association with clear cell meningioma, prospective and retrospective long-term follow-up is necessary for deciding whether reminiscent clear cell meningiomas should be separated from sclerosing meningioma or not.

Abstract
BACKGROUND AND AIMS Advanced neoplastic diseases alter the immune response in cancer patients. The aim of this study was to evaluate the changes of T-lymphocyte subsets during postoperative adjuvant chemotherapy, and the relationship between T-lymphocyte subsets and tumor recurrence in AJCC stage III gastric cancers. MATERIAL AND METHODS Analysis of T-lymphocyte subsets was performed in 39 patients with stage III gastric adenocarcinoma who had undergone a curative gastric resection and postoperative chemotherapy. CirculatingT-lymphocyte subsets were measured on venous blood by using flow cytometry and monoclonal antibodies on preoperative day 1, and postoperative months 1, 3, and 6. RESULTS The 5-year disease-free survival rates of patients with stage 3a and 3b gastric cancer were 57.1% and 33.3%, respectively (p = 0.06). Values of CD3+ and CD4+ T-cells, and CD4+/CD8+ ratios were consistently lower in the recurrence group throughout the observation period. CD4+ T-cell counts were significantly lower in the recurrence group on preoperative day 1, and postoperative months 1 and 6. However, most values of the T-lymphocyte subsets showed no statistically significant difference when comparing the stage 3a and 3b disease patient groups. CONCLUSIONS The results of this study suggest that immunosuppression associated with CD3+ and CD4+ T-cell depression is a risk factor for postoperative recurrence in patients with stage III gastric cancer.

Gliofibroma is a rare astrocytic neoplasm of young people that shows abundant deposition of collagenous matrix around glial cells. It shares some clinical and pathologic features with desmoplastic cerebral astrocytoma of infancy or desmoplastic infantile ganglioglioma. However, histogenesis or clinical behavior of these tumors is not fully known. Here, we report a case of gliofibroma with unusual extensive calcification which complicated radiologic as well as pathologic diagnosis.

Abstract
Meningioangiomatosis is a unique, rare hamartomatous lesion. Meningiomas arising in the background of meningioangiomatosis are rare conditions which pathologically and radiologically mimic invasive meningiomas, but have a benign clinical course in children and young adults. In this study, five such cases are reported. To our knowledge, this is the largest reported collection of meningiomas associated with meningioangiomatosis. Less immunoreactivity for progesterone receptor and high Ki-67 labelling index are generally known to be associated with invasive meningiomas. However, high expression of progesterone receptor and low Ki-67 labelling index in the present cases supports the idea that brain invasion is not an indicator of malignancy but an independent finding associated with meningiomas which have arisen from meningioangiomatosis. We emphasize the good prognosis of such tumours and discuss pathogenesis of meningiomas with meningioangiomatosis.

Abstract
We report a case of the unusual location of a cutaneous bronchogenic cyst on the abdominal wall. The patient was a 9-month-old boy who had presented with a 1.5 cm-sized polypoid mass, present since birth. Pathological examination of the excised mass revealed multiple small cystic structures surrounded by the fibroadipose tissue. The lining epithelium consisted of either pseudostratified ciliated columnar epithelium with goblet cells or a single layer of ciliated or non-ciliated cuboidal to columnar cells. The cystic walls contained a well-developed smooth muscle bundle, mucous glands and hyaline cartilage plate. This lesion was adherent to the peritoneum, but there was no direct communication with the abdominal cavity. Cutaneous bronchogenic cyst located in the abdominal wall has not been described in the English literature. The present case suggests a possible origin from a downward migration, from the sequestered bud of a tracheobronchial tree primordium along the midline of the body surface, during embryonic development.

Abstract
To find out whether the cryotherapy for the treatment of the retinopathy of prematurity (ROP) causes structural changes of the extraocular muscle (EOM), and also whether the changes are related with the occurrence of strabismus. To examine the acute stage change, we conducted a transconjunctival cryotherapy around the superior rectus muscle of a rabbit and resected it 0, 3, 7, 14, and 28 days after the cryotherapy. In observing chronic changes, we first categorized patients who had an esotropia surgery into groups, one of which combined prematurity and cryotherapy and one group affected by prematurity but without having had cryotherapy. Then we compared the change of EOM with that of a fullterm infant group. In a rabbit, edema, acute inflammatory cells and a large amount of degenerated muscle fibers were observed immediately after the cryotherapy and on the 3rd day. On the 7th day, regenerated muscle fibers were observed and on the 14th day, the inflammatory cells decreased and the amount of regenerated muscle fiber increased. On the 28th day, abnormal findings were not observed any more and the muscle was found to be normal. When chronic changes of EOM in human on 1 1/2 to 8 1/2 years after cryotherapy, there were no abnormal findings observed in three groups. From the study, we can infer that cryotherapy can cause acute inflammation and necrosis of muscle fiber but such an acute change will improve and does not result in structural change in the long term. Therefore, the occurrence of strabismus in patients with ROP is considered to be attributable to reasons other than injury of EOM.

Abstract
OBJECTS To investigate the characteristics of childhood meningioma, especially, locations, radiological findings, pathological features (including proliferative potential) and outcome, 11 children with meningiomas were retrospectively analyzed. RESULTS Unusual location, large size, frequent calcification, and cyst formation were characteristic radiological findings. Gross total resection was achieved in 8 patients, and there was recurrence in 2. Gamma knife radiosurgery was performed on residual and recurrent tumors. MIB-1 indices tended to be high in large tumors. Nine patients had a Karnofsky Performance Scale of more than 70 during the follow-up period of 10 months to 19.5 years. Surgical treatment rendered 4 of 5 epileptic patients seizure free. The childhood meningiomas examined had unusual locations, atypical radiological findings, and various proliferative potentials. CONCLUSIONS Complete resection is the treatment of choice. Gamma knife radiosurgery can be a good alternative for residual tumors and small recurrent tumors. The outcome of childhood meningiomas is good after surgery.

Abstract
Erdheim-Chester disease is a rare systemic disorder characterized by a fibrosing xanthogranulomatous infiltration of multiple organs. We report a case of Erdheim-Chester disease with diffuse necrosis leading to difficulty in making a prompt diagnosis. Radiologically, osteosclerotic lesions with osteolytic element involved metadiaphyses of both proximal tibia, and retroperitoneal infiltrations encasing both kidneys, both adrenals, and aorta were found. A biopsy of the tibia showed diffuse infiltration of foamy histiocytes, Touton-type giant cells, and fibroblastic cells associated with extensive coagulative necrosis. Immunohistochemically, foamy histiocytes were positive for CD68 and peanut agglutinin and negative for S-100 protein. A few Langerhans' cells, which were difficult to identify in hematoxylin-eosin stain, were highlighted by immunostain for S-100 protein. The patient received supportive therapy and was alive 1 1/2 years after diagnosis, with newly developed bilateral retrobulbar lesions and worsened heart failure.
