Abstract
Adjuvanted vaccines are administered through intramuscular injection. To perform appropriate injection using an appropriate needle in different age groups or different daily living activities, we investigated the depth from the skin surface to muscle fascia and bone in the deltoid muscle area in 156 elderly aged ≥ 50 years by ultrasonic echography. Subjects consisted of 50 healthy elderly aged 50−64 years, 50 subjects aged 65−74 years, and 56 subjects aged ≥ 75 years (20 outpatients, 18 who needed nursing care, and 18 bedridden in a nursing home). The mean depth ± 1.0 SD from the skin surface to muscle fascia was 7.52 ± 2.13 mm for subjects aged ≥ 75 years, being shorter than 9.16 ± 3.02 mm in those aged 50−64years (p < 0.01). The depth from the skin surface to bone was 22.54 ± 3.85 mm for subjects aged ≥ 75 years and 25.41 ± 4.24 mm for those aged 65−74 years, significantly shorter than those aged 50−64 years (p < 0.01), depending on the reduced muscle volume. The subcutaneous volume length was greater in females (8.29 ± 2.63 mm) than in males (5.62 ± 2.80 mm) aged 50−64 years (p < 0.01). A similar result was obtained in those aged 65−74 years, but there was no difference in the muscle volume length. Our study found that a five-eighths of an inch (16 mm) needle was an appropriate length for average-sized elderly aged ≥ 50 years, but it should be longer for those with large body sizes.

Abstract
BACKGROUND There are no consensus criteria for diagnosing upper urinary tract infections (UTI). Therefore, we conducted a study to assess whether bacterial colony counts of ≥ 103 CFU/ml are optimal for diagnosing upper UTIs among infants. METHODS This retrospective observational study included 673 patients (<4 months of age) with urine samples obtained by catheterization for bacterial cultures. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were obtained when cutoff values of 103, 104, and 105 CFU/ml were used for diagnosing upper UTIs. Upper UTI patients were divided based on cutoff values: Group A (103 CFU/ml), Group B (104 CFU/ml), and Group C (≥ 105 CFU/ml). RESULTS Of the 197 positive (≥ 103 CFU/ml) patients, 92 were diagnosed with an upper UTI. These patients were divided into Group A (n = 23), Group B (n = 16), and Group C (n = 53). No significant differences were detected in terms of clinical findings, including the incidence of vesicoureteral reflex. When cutoff values of 103, 104, and 105 CFU/ml were used for diagnosing upper UTIs, the sensitivity/specificity percentages were 100/81.3, 75.0/95.9, and 57.6/97.5, and the PPVs/NPVs were 46.7/100, 75.0/95.9, and 79.1/93.4. CONCLUSION Using ≥ 105 CFU/ml as a diagnostic threshold leads to approximately 40% of positive cases being missed. In contrast when ≥ 103 CFU/ml is used, all upper UTIs were identified. Therefore, bacterial colony counts of ≥ 103 CFU/ml should be considered the cutoff value for the diagnosis of upper UTIs in infants (< 4 months of age).

Abstract
Vesicoureteral reflux (VUR) is common condition in infants with febrile urinary tract infections (UTIs). Both VUR and febrile UTIs are risk factors for renal scars, characterized by glomerular hypertrophy with global or segmental sclerosis as cardinal features in pathology. Because renal scars may cause hypertension or chronic kidney diseases in later life, voiding cystourethrography (VCUG) has been mandatory for infants following their first febrile UTIs to identify VUR. However, increasing evidence suggests that the presence of VUR may not represent a direct risk factor for renal scars, which has led to an increase in the use of a stratified approach, in which VCUG is not performed for all patients. This study was conducted to verify whether the stratified approach is justified to identify infants at risk for renal scarring. The medical records of 306 infants with first febrile UTIs (median age, 4 months; 0-72 months) were reviewed. VUR was detected in 40.4% (67/166) of patients by the non-stratified approach, in which VCUG was performed in all patients. In contrast, VUR was identified in only 27.1% (38/140) of patients by the stratified approach, in which VCUG was performed only in the patients with high risk of developing renal scars. This difference in the discovery rate was significant (p = 0.02). Renal bladder ultrasonography had the sensitivities of as low as 45.7% and 52.9% in detecting VUR and in predicting renal scarring assessed by renal scintigraphy, respectively. In conclusion, VCUG should be performed in all infants after their first febrile UTIs.

Abstract
Twinkling artifact (TA) refers to the finding characterized by both a high-echoic mass upon B-mode ultrasound (US) and turbulence-like signals over the entire mass without significant blood flow on color Doppler US. TA is a characteristic sign of urolithiasis, and there has been no previous report on this finding in the digestive tract. The authors recently encountered a 2-year 9-month-old boy with cystinuria presenting with an opacified abdominal mass. Although he was originally diagnosed as having calcified stool mass, the finding of TA upon US led to the correct diagnosis of huge urolith (4.2 cm in diameter) in the urinary bladder. Laparotomic stone removal was successfully conducted and the calculus was confirmed to be composed of cystine. The finding of TA upon US facilitates identification of the structure and location of the intra-abdominal mass.

Abstract
Patients with Kawasaki disease (KD) who did not respond to the initial IVIG are known to have higher risk for developing coronary arterial lesions (CALs). Our aim is to clarify whether patients with initial IVIG resistant KD may benefit from methylprednisolone pulse therapy (MPT) in comparison with re- treatment of IVIG (2nd IVIG). A total of 237 patients (median age: 2 years 2 months; range 1 months-10 years) with KD were initially treated with IVIG (2 g/kg). Among them, 41 patients (22 %) were assessed as IVIG resistance: these patients were allocated to either group A receiving MPT (n = 14) or group B receiving the 2nd IVIG (n = 27). Patients with resistant to the additional therapy (MPT or 2nd IVIG) were received second IVIG (group A) or MPT (group B). Changes in leukocyte count, C-reactive protein and albumin before and after an additional therapy were significantly greater in group A than those in group B. However, the prevalence of CALs did not differ between the groups (36 % in group A and 26 % in group B, p > 0.05). There was no significant difference in the medical cost between the groups (median cost: 92,032 JPY in group A and 97,331 JPY in group B). MPT does not reduce the risk of development to CAL and does not seem to be beneficial as single agent therapy for IVIG resistant KD.

Abstract
It is known that ceftriaxone administration is associated with biliary pseudolithiasis, although the development of urolithiasis has been rarely reported. We encountered a young male with bacterial meningitis complicated by urinary precipitates composed of ceftriaxone-calcium salt which is confirmed by high-performance liquid chromatography. This patient suggested that ceftriaxone significantly increased urinary excretion of calcium, which may be linked to ceftriaxone-related urolithiasis or sludge. It is therefore worthwhile to monitor the levels of urinary calcium to creatinine ratio in patients on ceftriaxone, as they may be at greater risk for developing large stones and renal damage.

Abstract
AIMS Orthostatic dysregulation (OD) is common in adolescents. This study was conducted to evaluate the usefulness of the measurement of the diameter of the inferior vena cava (IVC) for objective assessment of patients with OD. METHODS Twenty children with OD (median 14 years, range 9-15 years) and 23 age-matched healthy children (median 12 years, range 10-15 years) were enrolled. A diameter of IVC was measured by an abdominal echogram before and after a head-up tilt table testing (HUT). Changes in IVC was assessed by an arbitrary parameter, collapse index (CI) as the following equation: [(maximal IVC diameter in the supine position - maximal IVC diameter in the standing position)/(maximal IVC diameter in the supine position)]× 100. CI was evaluated 4 weeks after treatment with an adrenergic agent. RESULTS Children with OD demonstrated either higher CI or lower CI compared to that in control children: CI was more than 50 (range 50-71) in 12 patients with OD while that was equal to or less than 0 (range -225 to 0) in eight out of 20 patients. In contrast, CI was between 0 and 50 (range 1-26) in 23 healthy children. Pharmacological treatment induced the normalization in the CI in both higher and lower CI group. CONCLUSION OD can be classified into two subtypes: by HUT, one is characterized by an increase of IVC diameter while another is characterized by its decrease. Measurement of IVC diameter by HUT is useful to understand the pathophysiology and to assess the efficacy of treatment.

Abstract
PURPOSE To investigate clinical outcomes with respect to the effectiveness of chemotherapy in the treatment of uterine leiomyosarcoma. METHODS Study subjects were 18 patients with uterine leiomyosarcoma treated surgically at our hospital between February 1986 and December 2007. A chemotherapy regimen that combined ifosfamide, epirubicine, and cisplatin (IEP) was used as the main first-line chemotherapy. RESULTS FIGO disease stages were as follows: Stage I (n = 11), Stage II (n = 1), Stage III (n = 3), Stage IV (n = 3). Five-year overall survival of patients with Stage I-III disease was 65.3% (95% CI: 46.1-92.4%). None of patients with Stage IV disease survived for more than two years. Of seven patients who suffered advanced or recurrent disease, six received IEP; the response rate was 50%, one complete response and two partial responses. CONCLUSIONS The combination of surgery and chemotherapy seems to be an acceptable treatment for uterine leiomyosarcoma. IEP may be an active regimen for this aggressive disease.

Abstract
Hyponatremia frequently occurs in Kawasaki disease (KD). The aim of this study was to investigate the effect of Na content of the intravenous immunoglobulin (IVIG) preparation on serum Na levels in KD. Seventy-eight subjects, of whom 27 had hyponatremia, were split up into two groups: group A receiving IVIG preparations containing high Na (0.9%) and group B receiving IVIG preparations containing trace Na. While the data before IVIG therapy revealed no significant differences in the median serum Na between the groups, an administration of IVIG preparations increased the serum levels of Na in group A (P < 0.01) but not in group B (P > 0.05). Furthermore, the median serum Na level was significantly higher in group A than that in group B (139.0 vs 137.0 mEq/L, respectively, P < 0.01). No significant difference was found in the prevalence of coronary artery lesions between the groups. In conclusion, we should keep it in mind that the IVIG products without Na have an adverse affect on hyponatremia in KD though their efficacy seems to be equivalent to those containing high Na.

Abstract
Prostate-specific antigen (PSA) screening has led to a remarkable increase in prostate cancer cases undergoing operative therapy. Over half of patients with locally advanced cancer (>or=pT3) develop rising PSA levels (biochemical failure) within 10 years. It is very difficult to predict which patients will progress rapidly to advanced disease following biochemical failure (BF). Therefore, a more useful prognostic factor is needed to suggest the most appropriate therapies for each patient. To determine chromosomal aberrations, we examined 30 patients with stage pT2 or pT3 primary prostate adenocarcinomas and no metastases (pN0M0) by comparative genomic hybridization (CGH). Laser capture microdissection (LCM) was used to gather cancer cells from frozen prostate specimens. Common chromosomal alterations included losses on 2q23-24, 4q26-28, 6q14-22, 8p12-22 and 13q21-31, as well as gains on 1p32-36, 6p21 and 17q21-22. Losses at 8p12-22 and 13q21-31 were observed more frequently in pT3 than pT2 tumors (P<0.05 and P<0.01, respectively). Losses at 8p12-22 were more frequent in tumors with BF (P<0.05), and those at 13q12-21 were more frequent in tumors with Gleason score (GS) 7 or more than lower GS (P<0.05). These findings suggest that losses of 8p12-22 and 13q21-31 are important determinants of prostate cancer progression.

Genomic DNA was extracted from whole blood collected from 56 patients with KD who received gamma-globulin treatment. The genotypes for Fcgamma RIIIb-NA(1, 2), Fcgamma RIIa-H/R131, and FcgammaRIIIa-F/V158 were determined to investigate the association between these polymorphisms and the development of coronary lesions (CALs). Twenty-three percent of patients with the HH allele for the Fcgamma RIIa polymorphism progressed to CALs, compared with 60% with the HR and RR alleles. HR and RR alleles may be a predictor of the progression of CALs in KD before the initiation of gamma-globulin therapy.

Abstract
BACKGROUND Adenoviruses are associated with a variety of diseases including upper respiratory tract infections, acute conjunctivitis, cystitis and gastroenteritis. Adenoviruses can also cause fatal disseminated infections in patients undergoing stem cell transplantation. Measurement of adenovirus load in clinical samples from localized adenovirus infections or disseminated adenovirus infections may provide important information for analyzing the pathogenesis of various adenovirus infections. The purpose of the present study was to develop and optimize a highly sensitive real-time polymerase chain reaction (PCR) assay to detect a wide range of adenoviruses and to detect adenovirus DNA in clinical samples from immunocompetent children. METHODS Clinical samples of throat swabs and blood were collected from 111 patients suspected of having adenovirus infection. The copy number of adenovirus DNA was measured by real-time PCR assay. RESULTS SYBR Green real-time PCR assay is able to detect 10-10(6) copies of standard adenovirus DNA per run. Adenovirus DNA was detected in all culture-positive samples serotyped as 1, 2, 3, 4, 5, 6, 8 and 11. Viral loads on throat swabs from immunocompetent children with adenovirus infection ranged from 10(5) to 10(11) copies/mL. Adenovirus DNA was detected in 60% of blood samples and copy number ranged from 10(3) to 10(5) copies/mL. CONCLUSION SYBR Green real-time PCR is a useful quantitative tool for analysis of adenovirus DNA. The present results for immunocompetent children with adenovirus infections provided basic data for comparison with data obtained from immunocompromised patients.

Abstract
Possible diabetes mellitus-induced changes in hippocampal monoaminergic activities were studied to understand the relationships between neurotransmitter levels and various abnormalities in freely moving diabetic rats. We used both experimentally (STZ rats) and spontaneously diabetic rats (WBN/Kob rats) as the diabetic animal model, and compared the findings with those obtained from non-diabetic rats (C rats). Measurement of neurotransmitters (serotonin and dopamine) was carried out using an in vivo microdialysis method. We found that: 1) the basal level of serotonin in the hippocampus was lowest in WBN rats, followed by STZ rats, then by C rats. The level of serotonin in WBN rats was about a half of that in C rats; 2) the basal level of dopamine was also significantly lower in the diabetic WBN and STZ rats than in C rats. The data show that diabetes mellitus decreases in the monoamine release from the hippocampus in both experimentally and spontaneously diabetic rats.

Abstract
We evaluated the usefulness of measurements of the inferior vena cava (IVC) diameters on abdominal echograms as an indicator of changes of venous return in subjects with orthostatic intolerance (OI) induced by simulated microgravity. We performed a standing test and recorded the IVC diameters on abdominal echograms in 12 subjects placed on a 20-day 6° head-down-tilt bed-rest experiment. We found that different patterns of changes in IVC diameter occurred in the standing test on day 10 of the experiment; in five subjects with a marginal decrease in pulse pressure, IVC diameters in the upright position were markedly decreased compared with those in the supine position. In five subjects with feelings of discomfort, the IVC diameters in the upright position distended or did not decrease from those in the supine position. These results suggested that the changes in IVC diameter on the standing test indicated the presence of various types of hemodynamic responses of OI caused by simulated microgravity. In this study, we also evaluated changes in body-water compartments by conducting multifrequency bioelectrical impedance analysis. Longitudinal data analysis showed that the total body-water-to-fat-free mass and extracellular fluid-to-fat-free mass ratios decreased during the experimental period and recovered thereafter, and that the ratio of intracellular fluid to fat-free mass decreased during the experiment. No significant difference in changes in body-water compartments was seen among subjects with different patterns of changes in IVC diameters. Measurement of IVC diameter was useful to estimate hemodynamic changes in subjects with OI.

Abstract
BACKGROUND Endogenous nitric oxide (NO) production increases with clinical conditions associated with immune stimulation. In Kawasaki disease (KD), various cytokines play a role in inflammatory reactions in the cardiovascular system. The authors hypothesized that elevated concentrations of nitrate was related to the severity of vasculitis. The aim of the present study was to evaluate serial changes of plasma nitrate concentrations in the acute phase of KD and to consider how NO is related to the inflammatory process of KD and to the coronary artery lesion (CAL). METHODS Thirty patients with KD and 20 age-matched healthy controls were enrolled in the present study. Blood samples were obtained weekly for the first and second months. The patients were divided into two groups: one with CAL (n = 11) and another without CAL (n = 19). Plasma nitrate was measured by high-performance liquid chromatography. RESULTS In both groups, plasma nitrate increased remarkably from the first week to the third week. Peak concentrations of nitrate (mean +/- SD, micro mol/L) in each group were as follows: 56.9 +/- 23.8 in the CAL(+) group and 68.2 +/- 33.8 in the CAL(-) group. Plasma nitrate decreased from the third week to the second month but was still elevated in both groups in comparison with the age-matched healthy controls. There was no correlation between plasma nitrates and white blood cell count or C-reactive protein, respectively (r = 0.013, 0.075). CONCLUSIONS The results suggest that NO production may not be related to the severity of vascular inflammation and that elevated nitrate during the first month of illness may not be associated with a higher risk of CAL.

Abstract
The clinical efficacy and safety of clarithromycin (CAM) and cefdinir (CFDN) were evaluated in 65 pediatric outpatients with group A beta-hemolytic streptococcal tonsillopharyngitis. Treatment was "effective" or better in 26 (78.8%) children receiving CAM and in 27 (87.1%) receiving CFDN based on antigen clearance and the "Criteria for Evaluation in Clinical Trials of Antibacterial Agents in Children" proposed by Japan Society of Chemotherapy (p = NS). The causative organisms were eradicated in 94.7% and 93.8% of subjects in the CAM and CFDN groups, respectively (p = NS). Adverse drug reactions were limited to moderate diarrhea in one patient in each group, and subsided during treatment. Causative organisms exhibited good susceptibility to CAM and CFDN. These results suggest excellent efficacy, safety and usefulness of CAM and CFDN in the treatment of group A beta-hemolytic streptococcal tonsillopharyngitsis in children.

Abstract
BACKGROUND Food allergy may be partly due to impairment of the intestinal barrier and is frequently associated with atopic dermatitis (AD) in early life. OBJECTIVE To determine whether bowel wall thickening, as demonstrated by US, is useful for the identification of food allergy. MATERIALS AND METHODS We used US to study eight infants with food allergy and ten non-allergic controls to clarify whether specific intestinal findings in the jejunum, ileum and colon are present in infants with AD who have food allergy. RESULTS Wall thickening was observed in all eight patients with food allergy, but only in the jejunum; it disappeared after elimination of suspected dietary allergens. Bowel wall thickening returned in the two allergic patients who received a food challenge test. CONCLUSIONS Wall thickening of more than 2 mm on US in the jejunum in infants with AD may be a useful marker to evaluate the presence of food allergy and therapeutic effects.

Abstract
Clinical studies of ceftriaxone (CTRX) were performed at a dose of 40 mg/kg once daily to evaluate its pharmacokinetics, and clinical and bacteriological efficacies in pediatric patients with respiratory tract infections. The following results were obtained. 1. Of 45 patients, clinical responses to CTRX were excellent in 34 (75.6%), good in 9 (20.0%) and poor in 2 (4.4%), indicating the overall efficacy rate of 95.6%. 2. Haemophilus influenzae (23 strains), Streptococcus pneumoniae (20 strains) and Moraxella catarrhalis (17 strains) were isolated from the patients as the main causative organisms. MIC90 of CTRX against these detected bacteria was < or = 0.06 microgram/ml with H. influenzae [beta-lactamase (-)/ABPC (S)], 0.25 microgram/ml with H. influenzae (BLNAR), 0.05 microgram/ml with PSSP, 1.0 microgram/ml with PISP/PRSP and 2.0 micrograms/ml with M. catarrhalis, respectively. 3. The eradication rate of causative organisms was 90.0% (27/30). 4. Serum levels of CTRX after administration of a 1-hour intravenous drip infusion of 40 mg/kg were investigated in 12 patients. Mean serum level at 24 hours after the administration was 9.4 +/- 2.8 micrograms/ml, which covered the level of MIC90 throughout the 24 hours. 5. No adverse reactions related to CTRX were observed. As the approved dosage of CTRX in pediatric patients is twice daily, while it is once daily in adults, there have been few reports on the efficacy of once-daily CTRX in pediatrics. According to the results of the study, it is suggested that once-daily CTRX for the pediatric patients with respiratory tract infections is useful. Further studies might be required to establish outpatient parenteral antibiotic therapy (OPAT) in pediatric infections.

Abstract
BACKGROUND It has been recently found that mice, especially males, with a disrupted angiotensin type 2 receptor (AT2R) gene, which is located on the X-chromosome, often have a range of congenital anomalies of the kidney and urinary tract (CAKUT), including renal hypoplasia, and that Caucasian male patients with ureteropelvic junction stenosis (UPJ) and multicystic dysplastic kidneys frequently have A-G transition in intron 1 of the AT2R gene. We have previously found that renal hypoplasia is remarkably predominant in Japanese boys. METHODS We investigated sex ratios for the frequency of each CAKUT. The frequency of the A-G transition between the controls and 66 Japanese boys with CAKUT were compared. There was renal hypoplasia in 16, UPJ in 17, vesicoureteral in 20, and other anomalies in 13. We also investigated whether any mutations in AT2R genes were detectable in patients with renal hypoplasia. RESULTS In contrast to mice with a disruption of the AT2R gene, the male-to-female ratios in human patients proved to be considerably variable: 16 for renal hypoplasia, 2.1 for UPJ, 0.8 for vesicoureteral, and 1.2 for others. The frequency of the A-G transition was not different between the control population and the patients with CAKUT [31 of 102 (30%) vs. 23 of 66 (35%), respectively]. A sequencing study disclosed no mutations in nine boys with renal hypoplasia. CONCLUSIONS These findings indicate that the AT2R gene may not play a major role in the development of renal hypoplasia and other CAKUT in humans, at least in the Japanese population.

Abstract
In the present study, we investigated the characteristics of the postrest contraction (PRC) in chronic diabetic ventricular muscle. We used WBN/Kob rats of 7-8 weeks as the spontaneously diabetic animal and Wistar rats of 7-8 weeks as the control. We found: (1) No significant differences were seen in the amplitude, the contracting speed, and the relaxing speed of electrically stimulated twitch tension between control and WBN/Kob rats. In addition, the relationship between amplitude of twitch tension and stimulus cycle lengths (0.2-5 sec) was very similar in both animals. (2) The ratios of the first twitch tension (T1) of PRC with various rest intervals (5-600 sec) to the steady-state tension (Tss) were significantly smaller in the diabetic rats than in the controls. (3) When the preparation was stimulated at shorter cycle lengths, the recovery process of PRC was separated into at least two components (fast and slow components). In the diabetic rats, the time constant (tau) of both components was significantly longer than in controls. (4) After caffeine (10(-3) M) treatment, tau of the fast component in the control rats became longer, whereas it remained unchanged in diabetic rats. These findings suggest a dysfunction of the intracellular calcium handling system in spontaneously diabetic heart that is likely to include impaired calcium sequestration and/or extrusion.

Abstract
BACKGROUND alpha,alpha-Trehalase, located on renal proximal tubules, is a glycoprotein that hydrolyses alpha,alpha-trehalose to two glucose molecules. Urinary trehalase reflects damage to renal proximal tubules, but its activity has not been measured routinely because measurement of catalytic activity is rather complicated and because conventional assays for enzyme activity might not reflect all of the trehalase protein because of enzyme inactivation in urinary samples. METHODS We established novel monoclonal antibodies for human trehalase and a sandwich ELISA for quantification of urinary trehalase. We determined the urinary trehalase protein concentration with this ELISA and trehalase catalytic activity, and the results of these two methods were compared. RESULTS The ELISA system was more sensitive than the detection of enzyme activity and could detect a subtle difference in the amount of trehalase present in renal diseases. The within- and between-assay CVs in the ELISA were 6.7-7.6% and 6.2-8.2%, respectively. Highly significant increases in both the quantity and activity were seen in patients with nephrotic syndrome (acute phase), Lowe syndrome, and Dent disease. The quantities were 70- to 200-fold greater, whereas enzyme activities were, at most, 10-fold higher than those of control subjects. In the detection of small amounts of trehalase in patients with chronic glomerulonephritis and renal anomalies, quantities were better than enzyme activities. CONCLUSIONS We have established an ELISA system for quantification of urinary trehalase that uses novel monoclonal antibodies. Our ELISA system is simpler and more sensitive than a conventional activity assay and reflects trehalase protein. This ELISA can be a useful as a common tool for clinical assessment of renal proximal tubular damage.

Abstract
UNLABELLED Funnel-type intraluminal duodenal diverticulum (windsock web) is a rare congenital malformation. A 4-year-old boy with vomiting and abdominal pain for several weeks was referred to the hospital. A plain abdominal X-ray on admission disclosed a double bubble sign. Abdominal echography and CT disclosed a foreign body lodged in the alimentary tract. After the foreign body was removed with a fibrescope, endoscopy showed a stenotic descending portion where the foreign body was located. An upper gastro-intestinal contrast study demonstrated a post-bulbar duodenal stenosis with a barium-filled pear-shaped sac in the descending portion of the duodenum. Surgical exploration was done under the diagnosis of windsock web of the duodenum. A simple excision of the web at its base was carried out. A hole 7 mm in diameter was found at the edge of the web. The microscopic appearance of the resected specimen was characterized by the duodenal mucosa with an extensive chronic inflammation lining both sides of the diverticulum and the lack of muscular layer of mucosa. CONCLUSION If an ingested material is not excreted in the stool, possible clogging in the intestinal tract should always be considered and a further intensive examination is warranted.

Abstract
UNLABELLED Adrenal enlargement was followed by serial ultrasonography in an infant with congenital lipoid adrenal hyperplasia (lipoid CAH) from day 12 until 2 years and 4 months of age, when they were no longer detectable. Contrary to other types of CAH in which the configuration changes soon after replacement therapy, this infant with lipoid CAH showed persistent adrenal cortex enlargement due to massive accumulation of lipids and cholesterol resulting in a damaged glandular cyto-architecture. CONCLUSION ultrasonographically persistent enlargement of the adrenals after replacement therapy is suggestive of the lipoid form of CAH.

Abstract
A complete cDNA clone encoding human trehalase, a glycoprotein of brush-border membranes, has been isolated from a human kidney library. The cDNA encodes a protein of 583 amino acids with a calculated molecular weight of 66,595. Human enzyme contains a typical cleavable signal peptide at amino terminus, five potential glycosylation sites, and a hydrophobic region at carboxyl terminus where the protein is anchored to plasma membranes via glycosylphosphatidylinositol. The deduced amino acid sequence of the human enzyme showed similarity to sequences of the enzyme from rabbit, silk worm, Tenebrio molitor, Escherichia coli and yeast. Northern blots revealed that human trehalase mRNA of approx. 2.0 kb was found mainly in the kidney, liver and small intestine. Expression of the recombinant trehalase in E. coli provided a high level of the enzyme activity. The isolation and expression of cDNA for human trehalase should facilitate studies of the structure of the gene, as well as a basis for a better understanding of the catalytic mechanism.

Abstract
The complete amino acid sequence of pokeweed lectin-B (PL-B) has been analyzed by first sequencing seven lysylendopeptidase peptides derived from the reduced and S-pyridylethylated PL-B and then connecting them by analyzing the arginylendopeptidase peptides from the reduced and S-carboxymethylated PL-B. PL-B consists of 295 amino acid residues and two oligosaccharides linked to Asn96 and Asn139, and has a molecular mass of 34,493 Da. PL-B is composed of seven repetitive chitin-binding domains having 48-79% sequence homology with each other. Twelve amino acid residues including eight cysteine residues in these domains are absolutely conserved in all other chitin-binding domains of plant lectins and class I chitinases. Also, it was strongly suggested that the extremely high hemagglutinating and mitogenic activities of PL-B may be ascribed to its seven-domain structure.

Abstract
We report the case of a 3-year-old boy with Ménétrier's disease who presented with prominent anasarca associated with hypoproteinemia, but no proteinuria. An early sonogram of the stomach demonstrated thickening of the gastric wall which was found to resolve gradually on serial sonograms. Consequently, we considered that the submucosal layer of the gastric wall was particularly thickened as a result of Ménétrier's disease. A gastric biopsy was performed 18 days after onset of the disease, and an electron-microscopic examination of the sample disclosed persistent widening of gastric tight junctions by more than 10 nm. The patient made a full recovery on supportive treatment in 3 weeks. Ultrasonography provided us with a potent tool not only in making the diagnosis, but also in following the course of the disease.

Abstract
The study was designed to examine cytosolic free calcium ((Ca2+)i) and phorbol dibutyryl ester binding in intact platelets of young obese subjects as compared with the platelets of age-matched subjects with non-insulin-dependent diabetes mellitus (NIDDM) and those of healthy control subjects. The assay was studied in basal and thrombin-stimulated conditions. The binding parameter of phorbol ester is a criterion for active protein kinase C (PKC) units in the platelet plasma membrane. The resting (Ca2+)i correlated with body mass index (BMI)(r = 0.385, p = 0.0034) and plasma insulin level (r = 0.316, p = 0.0269), and the resting (Ca2+)i level was higher in the obesity group (160.6 +/- 15.8 nmol/L; n = 25) than controls (78.9 +/- 7.6 nmol/L; n = 24, p < 0.0001). Among the obesity and control groups, there was a correlation between BMI and fasting plasma insulin level (r = 0.399, p = 0.0237). Systolic blood pressure correlated with BMI(r = 0.504, p = 0.0005). The mean systolic blood pressure of the obesity group was higher than those of the other two groups. The mean Hill coefficient for thrombin-treated platelets of phorbol dibutyrate binding was higher in the obesity group when compared with healthy controls and the subjects with NIDDM (1.47 +/- 0.21 vs 1.06 +/- 0.16 and 0.99 +/- 0.09, respectively; p < 0.05). In conclusion, young subjects with simple obesity have already developed altered platelet Ca2+ regulation that is usually observed in adult patients with a number of metabolic diseases. These data are interpreted to indicate that a relationship exists between dysregulation of PKC and impaired glucose tolerance that precedes other complications of obesity.

Abstract
Azithromycin (AZM), 10% fine granules or 100 mg capsules, were given orally to 27 children with various pediatric infections. The results of the study are shown below. 1. Pharmacokinetic investigation. We studied plasma and urinary concentrations after 100 mg AZM capsules were given. One patient received 8.3 mg/kg of AZM once a day for 3 days, and AZM concentration in plasma was 0.033 microgram/ml 48 hours after the final dosing. Doses of 8.3 and 12.5 mg/kg body weight of AZM were respectively given to two patients once daily for 3 days. As a result, AZM concentrations in urine during a period between 96 and 120 hours post-dosing were 1.67 and 4.53 micrograms/ml, respectively, and urinary excretion rate in 120 hours after the first dosing was 10.54% in the patient that was given 12.5 mg/kg. 2. Clinical investigation. Clinical efficacies were examined in 24 patients. Excellent results were obtained in 7 patients, good results in 14 patients, hence the clinical efficacy rate was 87.5%. Bacteriologically, Haemophilus influenzae strains isolates from 2 patients were eradicated in 1 and decreased in the other. Safety was evaluated in 26 patients. An adverse reaction was observed in 1 patient (urticaria). Abnormal laboratory test results were observed in 2 patients, decreased WBC in 1 and elevation of eosinophils in the other. The above results suggest that AZM is a useful oral antibiotic for pediatric patients with infection with susceptible organisms.

Abstract
The purpose of this study was to clarify the role of endothelin (ET)-1 in the development of bronchopulmonary dysplasia (BPD). Tracheal aspirates were obtained from 27 newborn babies with respiratory distress (13 with BPD and 14 without BPD) who were mechanically ventilated. Production of superoxide anion (O2-) by rabbit alveolar macrophages was determined by preincubation with the tracheal aspirate supernatant (TAS) and stimulation with phorbol myristate acetate (PMA). O2- production was demonstrated only when PMA was added to the experimental system and was enhanced with TAS of infants who later developed BPD compared with TAS from infants without BPD. The effects of ET-1 and ET-3 on O2- production and the blockade by anti-ET-1 antibody and BQ123 (ET A receptor antagonist) were also examined. The enhancing effect was blocked by either anti-ET-1 antibody or BQ123. PMA-stimulated production of O2- increased when cells were preincubated with several doses of ET-1 (5 x 10(-13) to 2 x 10(-12) M), whereas ET-3 was without effect. TAS contained significant amounts of immunoreactive ET-1, and there was a close positive correlation (r = 0.764) between the activity of O2- production and immunoreactive ET-1 levels in TAS samples. These results may be interpreted to indicate that ET-1 synthesized by and secreted from tracheal epithelial cells and/or alveolar macrophages has a priming effect on alveolar macrophages to produce O2-, thus possibly contributing to the development of BPD.

Abstract
Three mitogenic lectins, designated PL-A, PL-B, and PL-C, were purified from the roots of pokeweed (Phytolacca americana) using Q-Sepharose column chromatography followed by gel filtration on Sephadex G-75, hydrophobic chromatography on Butyl-Toyopearl, and FPLC on a Mono-Q column. PL-A, PL-B, and PL-C are acidic proteins having isoelectric points of 4.35 and their apparent molecular masses were 22, 48, and 21 kDa by SDS-polyacrylamide gel electrophoresis in the presence of 2-mercaptoethanol, respectively. The three lectins have similar amino acid compositions rich in half-cystine and similar N-terminal sequences, indicating that they are homologous proteins. Identical sequences of N-terminal regions and six corresponding tryptic peptides in PL-A and PL-B suggested that PL-A may be an N-terminal half fragment of PL-B. Although all of three lectins have mitogenic activities, PL-B is a mitogenic lectin with the most potent hemagglutinating and mitogenic activities, and PL-C has almost no hemagglutinating activity.

Abstract
A clinical study was performed on SY5555, a newly developed penem antibiotic, in children. SY5555 was given orally to 14 patients at 19-29 mg/kg/day in 3 doses for 4 to 12 days. Clinical evaluations were made on the 14 patients including 4 with pharyngitis, 7 with tonsillitis, one with urinary tract infection, and 2 with impetigo. Overall clinical effects were excellent in 2, good in 12, with an efficacy rate of 100%. Causative organisms (Staphylococcus aureus and Streptococcus pyogenes) were all eradicated. As to adverse reactions, mild diarrhea was observed in 4 patients. These data suggest that SY5555 is a useful oral antibiotic for the treatment of bacterial infections in children.

Abstract
Thiol and disulfide compounds were tested as an anti-HIV drug against transactivator (Tat)-mediated transactivation of HIV-1. Of all the compounds tested, thiamine disulfide, alpha-lipoic acid, and N-acetycysteine significantly depressed HIV-1 Tat activity. Thiamine disulfide alone in these compounds possessing anti-HIV-Tat activity markedly inhibited production of progeny HIV-1 in acute and chronic HIV-1-infected CEM at nontoxic concentrations of 500-1000 microM. Thiamine disulfide (500 microM) blocked 99.7% of HIV-1 production after 96 hr culture in acute HIV-1 (LAV-1) infection (m.o.i. = 0.002), whereas it inhibited 90-98% of HIV-1 production in chronic-infected cells (CEM/LAV-1, H9/MN, and Molt-4/IIIB). The results suggest that thiamine disulfide may be important for AIDS chemotherapy.

Abstract
Cefozopran (CZOP, SCE-2787), a new parenteral cephem, was evaluated for its antibacterial activity and clinical efficacy. CZOP, 24.0-78.0 mg/kg/day, was given to 11 pediatric patients in 3 dose a day via 30-minute drip infusion. Clinically evaluated were nine patients including 4 with acute pneumonia, 2 with urinary tract infections, 2 with lymphadenitis and 1 with sepsis. Two patients were excluded because of possible non-bacterial infections. Clinical efficacies were excellent in 5, good in 3 and fair in 1. Bacteriological responses were confirmed for 5 strains in 5 patients. Four strains were eradicated, but one strain was not. MICs of CZOP were equal to those of ceftazidime. Side effects or abnormal laboratory test results were observed in 3 patients; diarrhea in 1, elevated GPT in 1 and thrombocytosis in 1, but none of them was significant.

Abstract
A clinical study in children has been performed on S-1108, a newly developed cephem antibiotic. S-1108 was given orally to 30 patients, at doses between 8 and 12 mg/kg/day in 3 divided doses for 2 to 10 days. Clinical evaluations were made on 26 patients consisting of 12 patients of pharyngitis, 5 of tonsillitis and of impetigo, one each of bronchitis, cystitis, lymphadenitis and cellulitis. Overall clinical effects were excellent in 10, good in 15, fair in 1 with an efficacy rate of 96%. As to adverse reactions, mild diarrhea (2 patients) and transients elevation of transaminases (one patient) were observed. These data suggest that S-1108 is a useful oral antibiotic for the treatment of bacterial infections in children.

Abstract
Various allyl compounds were tested as anti-HIV reagents. Of all the allyl compounds tested, allyl disulfide (CH2 = CH-CH2-S-S-CH2-CH = CH2), allyl alcohol (CH2 = CH-CH2-OH), and its ester strongly depressed cell proliferation of HIV-1-infected cells. KC50 (50% killing concentration) of the allyl disulfide and the allyl alcohol were 34 microM and 10 microM, respectively. The allyl alcohol, in particular, completely inhibited cell growth of HIV-1-infected cells by a single injection at a concentration of 40 microM, ultimately killing the viable CEM/LAV-1 cells within 96 hr cultivation. No effect of the allyl alcohol and its esters on cell proliferation of CEM cells, which are a HIV-1 noninfected human T-cell cell line, was observed at the concentration range of 20 to 200 microM under the same experimental conditions. The results suggest that the effect of the allyl alcohol and its esters resulted in remarkable promotion of the cytopathic effect induced by HIV-1 virus.

Abstract
Cefprozil (CFPZ, BMY-28100), a new oral cephalosporin, was evaluated for its antibacterial activity and clinical efficacy. Thirty-four patients were treated with 7.7-36.2 mg/kg per day of CFPZ divided into 3 times. A total of 33 patients including 3 with acute pneumonia, 2 with acute bronchitis, 17 with acute upper respiratory tract infections, 4 with urinary tract infections, 1 with suppurative lymphadenitis and 6 with other soft tissue infections were evaluated for clinical efficacy except for 1 patient whose general conditions were too serious to continue to be treated with orally medication. Clinical effects were excellent in 8 patients and good in 23 but 2 cases were excluded because they were suspected for viral infections, hence the overall efficacy rate was 100%. Bacteriological responses were confirmed on 6 (66.7%) strains which were eradicated by the treatment out of 9 strains identified. CFPZ showed stronger antibacterial activities than those of cefaclor. Side effects or abnormal laboratory test results were observed in 2 patients; nausea and pallor of face in 1 patient and an increase of eosinophil in 1. The above findings suggest that CFPZ is a safe and useful antibiotics for the treatment of bacterial infections in pediatric patients.
