PURPOSE: The cross-protection of 7-valent pneumococcal conjugate vaccine (PCV7) against vaccine-related serotypes has been controversial. We investigated the serological properties of cross-protective antibodies against vaccine-related serotypes 6A, 6C, and 19A induced in young children aged 12-23 months after booster immunization of PCV7. METHODS: IgG and IgM antibody concentrations and opsonic index (OI) against vaccine serotypes 6B and 19F and vaccine-related serotypes 6A, 6C, and 19A were measured by ELISA and opsonophagocytic killing assay (OPA) in 4 selected immunesera. The serological properties and antigenic specificity of protective antibodies were determined by IgM depletion of immunesera, OPA, and competitive OPA against serogroup 6 and 19 pneumococci. RESULTS: Compared to pre-IgM depleted immunesera, OI of IgM-depleted immunesera against 6B and 19F decreased and OI against 6A, 6C, and 19A decreased, too. In competition OPA, free 6B and 19F polysaccharide completely inhibited the immune protection against vaccine-related serotypes 6A, 6C, and 19A as well as vaccine types 6B and 19F. CONCLUSIONS: The booster immunization of PCV7 certainly induced cross-protective antibodies against vaccine-related serotypes 6A, 6C, and 19A with both IgG and IgM isotypes. Furthermore, IgM antibodies are more highly contributed to opsonophagocytic activity against vaccine-related serotypes as well as most of vaccine types than do IgG antibodies. Further studies are needed for the more immunized sera in the children as well as adults.

BACKGROUND: In general, the outcomes of arthroscopic repair for superior labrum anterior to posterior lesions (SLAP) are favorable, however, persistent pain and limitation of motion are not rare complications. One of the possible cause is a “knot-ache”. This study evaluated the results of reoperation of symptomatic recurrent SLAP lesions and asked whether the knot is associated with postoperative complications. METHODS: Between 2005 and 2015, a total of 11 patients who had undergone arthroscopic SLAP repair were reoperated for recurrent symptomatic SLAP lesion. By retrospective chart review, operative findings, the visual analogue scale for pain (pVAS), the range of motion (ROM), and functional scores were analyzed. RESULTS: The mean age of the study participants was 38.3 years, and the mean follow-up period was 42.5 months. In the primary operation, there were nine cases of repairs with conventional knot-tying anchors and three cases with knotless anchors. Impingement of the knots during abduction and external rotation of the shoulder was observed in the all cases with knot-tying anchors. The mean pVAS, ROM, and functional scores significantly improved with reoperation. At the final follow-up, the mean satisfaction VAS was 8.3. CONCLUSIONS: The knots of suture anchor maybe a possible etiology of the pain, which we termed a “knot-ache”. Considering that reoperation is performed due to pain after primary repair, the use of knotless suture anchor may have benefits of eliminating one of possible cause, “knot-ache”. Therefore, authors suggest the use of knotless anchors during reoperation for recurrent or recalcitrant pain after primary SLAP repair.

The kidney size is of special interest during the diagnostic work up of acute lymphocytic leukemia. But is still uncertain whether a finding of kidney enlargement at presentation has long-term prognostic value. We therefore reviewed the kidney size in children with acute lymphocytic leukemia by abdominal ultrasonograms at the time of diagnosis (n=54) and exmined if there was any statistical significance between the kidney size and prognostic parameters and later outcome. The following results were obtained 1) Among the patients whose kidney size was enlarged over 4SD from the normal, hepatomegaly in 3 cases (20%), splenomegaly in 3 cases (20%), mediastinal widening in 2 cases (13%) were noted. The interrelation between kidney size and infiltration of extramedullary system had no statistical significance. 2) Among the patients whose kidney size was enlarged over 4SD from the normal, patients under age 2 and over age 10 in 5 cases (33%), male in 8 cases (53%), involvement of central nervous system in 1 cases (7%), WBC count over 100x10E9/L in 3 cases (20%), Hb over 10 g/dl in 3 cases (20%) and platelet count below 100x10E9/L in 3 cases (20%) were noted. There was no statistical significance between kidney size and infiltration of extramedullary system. 3) Two Year survival rate based upon kidney size was; 95% in the group below 2SD, 79% between 2SD and 4SD, 59% over 4SD. And 2 Year event free survival rate was 71%, 56% and 58 respectively. In conclusion, the kidney size in childhood acute lymphocytic leukemia at the time of diagnosis influences the late outcome, but it is not a meaningful prognostic parameters.

Prostate cancer has long been considered a disease with a heterogeneous phenotype. The intratumor heterogeneity (ITH) may affect diverse phenotypes such as treatment response, drug resistance, and overall clinical outcomes. Despite technical advances over the past decade, we have an incomplete understanding of the extent and effects of ITH in prostate cancer progression. We present here a comprehensive review of the various studies dealing with ITH in prostate cancer. We discuss the advanced next-generation sequencing analyses including single cell sequencing and circulating cell-free DNA sequencing that have the impact of heterogeneity on clinical decision making.

BACKGROUND: Apoptosis plays a role in the development of pleural effusion. Caspase-cleaved cytokeratin 18, a marker for epithelial cell apoptosis, was evaluated in pleural effusion. METHODS: A total of 79 patients with pleural effusion were enrolled. The underlying causes were lung cancer (n=24), parapneumonic effusion (n=15), tuberculous effusion (n=28), and transudates (n=12). The levels of M30, an epitope of caspase-cleaved cytokeratin 18, were measured in blood and pleural fluids using enzyme-linked immunosorbent assay along with routine cellular and biochemical parameters. The expression of M30 was evaluated in the pleural tissues using immunohistochemistry for M30. RESULTS: The M30 levels in pleural fluid were significantly higher in patients with tuberculosis (2,632.1+/-1,467.3 U/mL) than in patients with lung cancer (956.5+/-618.5 U/mL), parapneumonic effusion (689.9+/-413.6 U/mL), and transudates (273.6+/-144.5 U/mL; all p<0.01). The serum levels were not significantly different among the disease groups. Based on receiver operating characteristics analysis, the area under the curve of M30 for differentiating tuberculous pleural effusion from all other effusions was 0.93. In the immunohistochemical analysis of M30, all pathologic types of cancer cells showed moderate to high expression, and the epithelioid cells in granulomas showed high expression in tuberculous pleural tissues. CONCLUSION: Caspase-cleaved cytokeratin 18 was most prominently observed in tuberculous pleural effusion and showed utility as a clinical marker. The main source of M30 was found to be the epithelioid cells of granulomas in tuberculous pleural tissues.

Cutis marmorata telangiectatica congenita (CMTC) is a rare congenital vascular disorder, and its pathophysiology is still unclear and most cases occur sporadically. Cutaneous lesions are observed at birth with a marbled bluish and deep-purple appearance. The associated anomaly is manifest as body asymmetry, macrocephaly, hydrocephalus, mental retardation, syndactyly and congenital glaucoma. We report our experience of CMTC1 in a female infant with the gestational age of 34 weeks and 6 days and birth weight of 2,300 g who was born by cesarean section with abnormal skin lesions. The cutaneous lesions covered most of the lower body and they faded as she continues to grow. She also had onychodysplasia in her left 2nd phalanges. In this case, close follow up by not only pediatricians but also ophthalmologist and neurologists to treat various forms of lesions involved, though the prognosis of CMTC is generally good.

BACKGROUND: As Koreans have had great enthusiasm for education traditionally, most students have excessive anxiety about tests and such anxiety may cause several physical and psychological problems. But there are few studies on the relationship between test anxiety and family function. Therefore, in this study, we tried to figure out the relationship between test anxiety and family function in order to treat and educate patients who have excessive test anxiety. METHODS: In a survey study, the Korean Version of Test Anxiety Inventory and Olson's FACES III was administered to the 220 second year high school students of a single high school who live in Pusan. Two groups of students with high and low test anxiety levels (52 in each group) were selected based on the test anxiety scale ratings and analysis of their family adaptability and cohesion. RESULTS: In FACES III adaptability of high test anxiety group, there were 15 cases (28.8%) for rigid, 23 cases (44.2%) for structured, 11 cases (21.2%) for flexible and 3 cases (5.8%) for chaotic familes. In that of low test anxiety group, 2 cases (3.8%) for rigid, 16 cases (30.8%) for structured, 24 cases (46.2%) for flexible and 10 cases (19.2%) for chaotic familes. In FACES III cohesion of high test anxiety group, there were 2 cases (3.8%) for disengaged, 14 cases (26.9%) for separated, 20 cases (38.5%) for connected and 16 cases (30.8%) for enmeshed familes. In that of low test anxiety group 18 cases (34.6%) for disengaged, 22 cases (42.3%) for separated, 8 cases (15.4%) for connected and 4 cases (7.7%) for enmeshed familes. In FACES III family type of high test anxiety group, there were 24 cases (46.2%) for balanced, 20 cases (38.4%) for mid range and 8 cases (15.4%) for extreme familes. In that of low test anxiety group 24 cases (46.2%) for balanced, and 22 cases (42.3%) for mid range and 6 cases (11.5%) for extreme familes. CONCLUSION: Cohesion scale of high test anxiety group was higher than that of low test anxiety group and adaptability scale of low test anxiety group was higher than that of high test anxiety group.

PURPOSE: To know the rate of optic disc cupping and visual field progression with correlation among them, and identify clinical factors associated with them. METHODS: Forty patients with POAG who treated over 10 years were evaluated, Cup progression rate was evaluated by using computer-aided planimetry and visual field declination was evaluated with Goldmann perimetry and manual grid template system. Optic disc cupping and visual field progression correlations were estimated using linear regression and all related clinical factors were evaluated using a multiple regression model. RESULTS: Optic disc cupping progression started from inferotemporal to superonasal, to superotemporal and to inferonasal portion (total 0.0067/year) and visual field loss progressed superonasal, inferonasal, superotemporal, inferotemporally (total -1.07%/year) in order with significant correlation. Incisional surgery before visit and higher yearly average higher intraocular pressure showed faster optic disc cup progression and higher initial intraocular pressure and lesser antiglaucoma medications at initial visits showed faster visual field progression. CONCLUSIONS: In treated patients with POAG, the rate of disc cupping and visual field decline showed slow progression rate with significant correlation and various clinical factors affected.
