Chronic sclerosing sialadenitis, Mikulicz disease or Kuttner tumor has been recently recognized as a spectrum of IgG4-related sclerosing disease. IgG4-related disease is characterized by a high serum IgG4 level and tissue infiltration of IgG4-positive plasmacytes. We report three cases of chronic sclerosing sialadenitis with variably associated systemic involvement. All patients presented with a submandibular mass or swelling, and all the resected submandibular glands showed diffuse lymphocytic infiltration, lymphoid follicles, and septal fibrosis. Two of the specimens revealed numerous IgG-positive plasma cells, most of which were IgG4-positive on immunohistochemical staining. One of them was associated with dacryoadenitis and hypophysitis. The other patient had ureterorenal lesions. Immunohistochemical study was unavailable in remaining one case, but the histologic features along with elevated IgG level and associated pancreatitis supported the diagnosis. All patients received steroid therapy postoperatively and are doing well. Salivary gland involvement in IgG4-related fibrosclerosis should be recognized in systemic medical pathology.

Alveolar soft-part sarcoma of the female genital tract are extremely rare. Fewer than 30 cases have been described in the literature. We experienced a case of alveolar soft-part sarcoma of the female genital tract which was diagnosed by routine light microscopic study using ultrastructural and immunohistochemical stain. We report this case with a brief review of the literature.

The incidence of inadvertent posterior capsular rupture at each stage of planned ECCE and posterior chamber intraocular lens implantation was studied. From June 1985 to Dec. 1986, 133 cases of planned ECCE for posterior chamber intraocular lens implantation were performed. Posterior capsular rupture with or without vitreous loss was developed in 11 cases(8.2%) out of 133. The rupture occurred during nuclear expression in 2 cases(1.5%), during cortical clean-up in 6 cases(4.5%), during remval removal of anterior capsular flaps in 2 cases(1.5%), during posterior chamber intraocular lens implantation in 1 case(0.7%), but during posterior capsule polishing in nocase(0%). Vitreous loss was combined with posterior capsular rupture in 6 cases(4.5%), but the other 5 cases were not associated with vitreous loss(3.7%). After management of vitreous loss by automated anterior vitrectomy in 10 cases, anterior chamber intraocular lens was implanted. But in the other 1 cases with mid posterior capsular rupture without vitreous loss, anterior chamber intraocular lens was implanted without anterior vitrectomy. A final visual acuity of 0.5 or better by 2 months postoperatively was observed in 10 cases out of 11(91%).

Purpose: The aim of this study was to evaluate the effects of four surface treatment methods to improve zirconia roughness and three types of resin cement on the shear bond strength (SBS). Materials and methods: A total of 120 zirconia blocks were randomly divided into four surface treatments: non-treatment (Control), airborne-particle abrasion (APA) with 50 μm Al2O3 (APA50), APA with 125 μm Al2O3(APA125), and ZrO2 slurry (ZA). Three resin cements (Panavia F 2.0, Superbond C&B, and Variolink N) were applied to the surface-treated zirconia specimens. All specimens were subjected to SBS testing using a universal testing machine. The surface of the representative specimens of each group was observed by scanning electron microscope (SEM). SBS data were analyzed with oneway ANOVA, two-way ANOVA test and post-hoc Tukey HSD Test (α=.05). Results: In the surface treatment method, APA125, APA50, ZA, and Control showed high shear bond strength in order, but there was no significant difference between APA125 and APA50 (P >.05). Also, ZA showed significantly higher shear bond strength than Control (P <.05). In the resin cement type, Panavia F 2.0, Superbond C&B, and Variolink N showed significantly higher shear bond strength in order (P <.05). In SEM images, the zirconia surfaces of the APA50 and APA125 showed quite rough and irregular shapes, and the zirconia surface of the ZA was observed small irregular porosity and rough surfaces. Conclusion APA and ZrO 2 slurry were enhanced the surface roughness of zirconia, and Panavia F 2.0 containing MDP showed the highest shear bond strength with zirconia.

PURPOSE:To evaluate the neonatal statistics on a national basis, data for birth characteristics and neonatal mortality were collected and analyzed from 57 hospitals in Korea. METHODS:Questionnaires were distributed to determine the characteristics of neonatal births and mortality rates in 57 hospitals in Korea during 2007. We analyzed the characteristics of all inborn births and hospitalized neonates in the neonatal care units (NICUs) and compared the results with published Korean data from 1996 and 2002. RESULTS:A total of 40,433 inborn live births were reported from the 57 hospitals during 2007. Pre-term, term, and post-term births comprised 24.2%, 75.6%, and 0.2% of the neonates, respectively. Low birth weight infants (LBWIs), very low birth weight infants (VLBWIs), and extremely low birth weight infants (ELBWIs) made up 22.0%, 4.6%, and 1.7% of the neonates, respectively. A total of 21,957 (collected by gestational period) and 21,356 (collected by birth weight) neonates were hospitalized in the 57 NICUs. Pre-term, term, and post-term neonates comprised 39.8%, 59.8%, and 0.4% of the neonates, respectively. LBWIs, VLBWIs, and ELBWIs made up 37.3%, 9.5%, and 3.3% of the neonates, respectively. Pre-term, term, and post-term neonates had mortality rates of 4.5%, 0.7%, and 3.7%, respectively, while the mortality rates of LBWIs, VLBWIs, and ELBWIs were 4.7%, 15.3%, and 32.2%, respectively. In comparison with prematurity data from 1996 and 2002, LBWIs, and ELBWIs had a marked increase in birth frequency and a decreased mortality rate in Korea during 2007. CONCLUSION:The number of live births and the survival rate of pre-term neonates, especially VLBWIs and ELBWIs, are increasing. Even though the outcomes of neonatal care are improving, further efforts to manage these premature infants are needed.

PURPOSE: Recently, Forkhead box M1 (FoxM1) was reported to be correlated with lung maturation and expression of surfactant proteins (SPs) in mice models. However, no study has been conducted in rabbit lungs despite their high homology with human lungs. Thus, we attempted to investigate serial changes in the expressions of FoxM1 and SP-A/B throughout lung maturation in rabbit fetuses. MATERIALS AND METHODS: Pregnant New Zealand White rabbits were grouped according to gestational age from 5 days before to 2 days after the day of expected full term delivery (F5, F4, F3, F2, F1, F0, P1, and P2). A total of 64 fetuses were enrolled after Cesarean sections. The expressions of mRNA and proteins of FoxM1 and SP-A/B in fetal lung tissue were tested by quantitative reverse-transcriptase real-time PCR and Western blot. Furthermore, their correlations were analyzed. RESULTS: The mRNA expression of SP-A/B showed an increasing tendency positively correlated with gestational age, while the expression of FoxM1 mRNA and protein decreased from F5 to F0. A significant negative correlation was found between the expression levels of FoxM1 and SP-A/B (SP-A: R=-0.517, p=0.001; SP-B: R=-0.615, p<0.001). CONCLUSION: Preterm rabbits demonstrated high expression of FoxM1 mRNA and protein in the lungs compared to full term rabbits. Also, the expression of SP-A/B was inversely related with serial changes in FoxM1 expression. This is the first report to suggest an association between FoxM1 and expression of SP-A/B and lung maturation in preterm rabbits.
