Hemangiopericytoma was first described by Stout & Murray in 1942 and was an uncommon soft tissue tumor thought to be derived from vascular pericytes. Approximately 10-15% of the cases occur in children have a propensity to develop in the region of head, neck and lower extremities. We experienced a case of congenital hemangiopericytoma of small bowel in a male neonate who showed vomiting and abdorninal distension. We reported a case of congenital hemangiopericytoma of small bowel with brief review of related literature.

This is a clinical analysis and review of one-hundred ninety-four patients with periappendiceal abscesses who were treated at the Departmeat of Surgery, Masan Samsung Hospital over a ten year period from January 1985 to December 1994. The following results were obtained. The incidence of periappendiceal abscesses was 7.24% of the total cases of appendicitis operated on during the same period, and most of the patients(43.8%) were over fifty years old. The male to female ratio was 1:1.02. 41.2% of the patients had operations within four days after their symptoms occurred. On admission, the most common physical finding was tenderness on the right lower quadrant of the abdomen (92.9%) and leukocytosis(> OR = 10,000/mm3) was noted on CBC in 82% of the patients. Abdominal sonograms revealed periappendiceal abscesses in 88% of the patients, 83% were revealed with barium enema and 88% with abdominal CT scan. Many patients(75.5%) visited the local clinic and were treated under the diagnosis of gastritis or enteritis instead of appendicitis. One-hundred eighty-three patients(94.3%) had appendectomies with drainages(94.3%), two patients had drainages of abscesses without appendectomy, six patients had ileocecal resections and three patients had right hemicolectomies. Microbiologically, E. coli was the most frequently cultured species(63%) from abscess, and Klebsiella, Enterococcus and Proteus were isolated in some cases. Postoperative complication occurred in seventy-five patients(38.6%) and the most frequent complication was wound infection(28.8%). There was no mortality and the mean hospital stay was fifteen days.

The brain metastasis of prostatic carcinoma is rare and is distinguished by its poor prognosis in cases which are not surgically resectable. Herein we described a 72 year old male with brain metastasis from prostatic carcinoma, which regressed with chemotherapy. Pathological examination of a transrectal needle biopsy disclosed moderatedly differentiated adenocarcinoma of the prostate. Magnetic resonance imaging of brain demonstrated a brain tumor at the occipital lobe suspected to be a metastasis of prostatic carcinoma. The tumor could not be detected on the brain MRI after 3 months of chemotherapy.

8.Intervention meta-analysis: application and practice using R software

Epidemiology and Health 2019;41(1):e2019008-
The objective of this study was to describe general approaches for intervention meta-analysis available for quantitative data synthesis using the R software. We conducted an intervention meta-analysis using two types of data, continuous and binary, characterized by mean difference and odds ratio, respectively. The package commands for the R software were “metacont”, “metabin”, and “metagen” for the overall effect size, “forest” for forest plot, “metareg” for meta-regression analysis, and “funnel” and “metabias” for the publication bias. The estimated overall effect sizes, test for heterogeneity and moderator effect, and the publication bias were reported using the R software. In particular, the authors indicated methods for calculating the effect sizes of the target studies in intervention meta-analysis. This study focused on the practical methods of intervention meta-analysis, rather than the theoretical concepts, for researchers with no major in statistics. Through this study, the authors hope that many researchers will use the R software to more readily perform the intervention meta-analysis and that this will in turn generate further related research.

The objective of this paper is to describe general approaches of diagnostic test accuracy (DTA) that are available for the quantitative synthesis of data using R software. We conduct a DTA that summarizes statistics for univariate analysis and bivariate analysis. The package commands of R software were “metaprop” and “metabin” for sensitivity, specificity, and diagnostic odds ratio; forest for forest plot; reitsma of “mada” for a summarized receiver-operating characteristic (ROC) curve; and “metareg” for meta-regression analysis. The estimated total effect sizes, test for heterogeneity and moderator effect, and a summarized ROC curve are reported using R software. In particular, we focus on how to calculate the effect sizes of target studies in DTA. This study focuses on the practical methods of DTA rather than theoretical concepts for researchers whose fields of study were non-statistics related. By performing this study, we hope that many researchers will use R software to determine the DTA more easily, and that there will be greater interest in related research.
