Background: Injury surveillance is viewed as an important component of injury prevention. Several data systems in the Philippines exist but have not been analyzed together. Analyzing these readily available data can guide policy making. Objective: This report aimed to describe the epidemiology of injuries in the Philippines using secondary datasets. Method: Death data of 2013 from the Philippines Statistics Authority and injury surveillance data of 2014 from the Department of Health were obtained and recoded. Summary statistics were generated. Results: Injured persons mainly come from the young age group. There were a higher number of males compared to females. Provincial variations in death rates for specific injury types existed. There did not seem to be an obvious pattern in injury occurrence according to month and time of day. High numbers of injuries were reported during daytime but admission and death rates peak at night. Injuries were shown to be an anatomically heterogeneous group with dominance in superficial injuries, head trauma, and hand fractures. Conclusion Analysis of secondary datasets revealed the epidemiology of injuries in the Philippines. Results have implications in health policy and injury prevention.

OBJECTIVETo investigate the risk factors of metachronous bone metastasis after radical resection of colorectal cancer within 5 years.

METHODSClinical data of 1 749 patients with colorectal cancer, of whom 50(2.8%) patients developed metastasis to bone after operation, in the Department of Colorectal Surgery, Changhai Hospital of The Second Military Medical University from January 2001 to December 2010 were analyzed retrospectively. Univariate and multivariate analysis were performed to find the risk factors of metachronous bone metastasis from colorectal cancer using Chi square test and Logistic regression, respectively.

RESULTSOf 50 colorectal cancer cases with bone metastasis, 29 were male and 21 were female. The age was ≥ 60 years old in 28 cases. Tumors of 36 cases were located in the rectum and of 14 cases located in the colon. Pathology examination showed 43 cases were adenocarcinomas, 7 cases were mucinous adenocarcinoma. Forty-two cases had T3-4 stage lesions, 30 cases had lymph node metastasis, 14 cases had pulmonary metastasis, and 5 cases had liver metastasis. Univariate Chi square test indicated that factors associated with the metachronous bone metastasis of colorectal cancer within 5 years were tumor site (χ=4.932, P=0.026), preoperative carbohydrate antigen 199 (CA199) level (χ=4.266, P=0.039), lymph node metastasis (χ=13.054, P=0.000) and pulmonary metastasis(χ=35.524, P=0.000). The incidence of bone metastasis in patients with rectal cancer (3.6%, 36/991) was higher compared to those with colon cancer (1.8%, 14/758). The incidence of bone metastasis in patients with higher(> 37 kU/L) preoperative serum CA199 level (4.9%, 12/245) was higher compared to those with lower serum CA199 level (2.5%, 38/1504). The incidence of bone metastasis in patients with lymph node metastasis(4.8%,30/627) and pulmonary metastasis (11.6%, 14/121) was significantly higher compared to those without lymph node metastasis (1.8%, 20/1122) and pulmonary metastasis(2.2%, 36/1628), respectively. Logistic multivariate analysis showed that rectal cancer(OR:0.508, 95%CI:0.268 to 0.963, P=0.038), lymph node metastasis (OR:2.291, 95%CI:1.273 to 4.122, P=0.006) and metachronous pulmonary metastasis(OR:4.796, 95%CI:2.473 to 9.301, P=0.000) were the independent risk factors of metachronous bone metastasis of colorectal cancer within 5 years.

CONCLUSIONPatients with rectal cancer, lymph node metastasis and metachronous pulmonary metastasis are high risk groups of metachronous bone metastasis after radical resection of colorectal cancer within 5 years.

PURPOSE: We conducted a prospective single-center study to evaluate the possibility of discontinuation of dutasteride after combination therapy with an alpha blocker for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: We prospectively treated BPH patients with an alpha blocker and dutasteride (0.5 mg/d). Patients who had been treated with alpha blockers against BPH for more than 2 months were eligible, and 20 patients were included in the study. After 6 months of combination therapy, dutasteride was discontinued. Patients were followed for 12 months after cessation. Prostate volume, intraprostatic architecture determined by transrectal ultrasound, peak urinary flow rate, postvoid residual urine volume, and the serum prostate-specific antigen level were evaluated every 6 months, and the International Prostate Symptom Score and overactive bladder symptom score (OABSS) every 3 months. Patients were allowed to restart dutasteride during the follow-up period according to their desire. RESULTS: Twelve patients (12/20, 60%) restarted the combination therapy from 6 to 12 months into the follow-up period. For patients who restarted dutasteride, the prostate volume and OABSS had increased and worsened after discontinuation, respectively. A visible transition zone with a clear border on transrectal ultrasound at baseline and regrowth of the prostate after discontinuation of dutasteride were risk factors for restarting the therapy (Mann-Whitney U test: p=0.008, p=0.017). CONCLUSIONS: Prostatic enlargement after discontinuation of dutasteride differs among patients. Rapid regrowth of the prostate leads to deterioration of storage symptoms and a tendency to restart dutasteride. Baseline intraprostatic architecture may be a predictive factor for whether the patient is a good candidate for discontinuation.

BACKGROUND/AIMS: The efficacy of surveillance for esophageal squamous cell neoplasia (ESCN) in patients with head and neck squamous cell carcinoma (HNSCC) remains controversial. Our study aimed to provide clinical data concerning the necessity of surveillance for detecting early ESCN in patients with HNSCC. METHODS: We retrospectively reviewed the data from 714 patients who were pathologically confirmed as having HNSCC (n=236 oral cavity cancers, 137 oropharyngeal cancers, 87 hypopharyngeal cancers, and 254 laryngeal cancers). RESULTS: Of 714 patients, during a median follow-up of 31 months, 48 ESCNs (37 synchronous and 11 metachronous) were detected in 36 patients (5%). Fifteen synchronous lesions (40.3%) were early ESCN, whereas nine metachronous lesions (81.8%) were early ESCN. The 3-year survival rates of HNSCC only and HNSCC combined with ESCN were 71.2% and 48.2%, respectively (p<0.001). Among 36 patients with ESCN, the 3-year survival rates for early and advanced ESCN were 77.7% and 21.7%, respectively (p=0.01). In the multivariate analysis, alcohol consumption and hypopharyngeal cancer were significant factors associated with the development of ESCN. CONCLUSIONS: HNSCC patients with early ESCN were similar in prognosis with patients without ESCN, in contrast to patients with advanced ESCN. Therefore, surveillance for the early detection of ESCN in patients with HNSCC, especially in alcohol drinkers and those with hypopharyngeal cancer, is warranted.

Mevalonate kinase (MVK) is a key enzyme in plant terpenoid biosynthetic pathway. This study focused on cloning and analysis of Panax notoginseng (Burk.) F. H. Chen MVK (PnMVK1) gene. After searching the transcriptome dataset of P. notoginseng, one unique sequence encoding MVK was discovered. The primers were designed according to the transcript sequence of PnMVK1 from the P. notoginseng transcriptome dataset. And then, the open reading frame of PnMVK1 was cloned from P. notoginseng by using RT-PCR strategy. The physical and chemical properties, secondary structure and three-dimensional structure of the PnMVK1 protein were forecasted and analyzed, and its structure and function were predicted. The cDNA (named as PnMVK1) contains a 1164 bp open reading frame and encodes a predicted protein of 387 amino acids. The GenBank accession number for this gene is JQ957844. No transmembrane region and signal peptide were present in PnMVK1. The conserved domain of mevalonate kinase was present in PnMVK1. PnMVK1 was more abundant in P. notoginseng root than other organisms. This study cloned and analyzed PnMVK1 gene from P. notoginseng for the first time. The result will provide a foundation for exploring the mechanism of terpenoid biosynthesis in P. notoginseng plants.

Approximately 5-30% of the ovarian cancers are metastatic malignancies. The prevalence of metastatic ovarian tumors varies with the incidence rates and spread patterns of primary malignancies. We evaluated the prevalence, pre- and postoperative characteristics of metastatic ovarian cancer in Korean women. We reviewed the records for 821 ovarian malignancies with pathological consultation from 1996- 2006 and recorded patient demographical, radiological, histopathological, and survival data. The study included 112 cases of histologically confirmed metastatic ovarian cancer. Metastatic ovarian cancer accounted for 13.6% of all ovarian malignancy, primarily arising from the gastrointestinal tract. The preoperative detection rate with imaging was 75%, and none of the radiological or serological features were useful for differential diagnosis. In multivariate analysis for prognostic variables, the only significant factor was the primary tumor site (p=0.004). Furthermore, extensive resection increased survival for some patients. The differential diagnosis of metastatic ovarian cancer can be problematic, so multiple diagnostic approaches are necessary. The extent of cytoreductive surgery for this type of tumor must be decided on a case-by-case basis.

In the patients with brain metastasis (BM), it is impossible to determine who will benefit from surgery because of limited survival. In an attempt to identify optimal candidates for brain metastatectomy, we analyzed patients who survived for <3 months after craniotomy for a single BM lesion. Between January 1st, 1997 and July 31st, 2007, 83 patients with a single BM underwent craniotomy. Of these patients, 25 patients (30.1%) died within 3 months of craniotomy. The primary lesions were non-small call lung cancer in 15, colon cancer in 6, and breast cancer, renal cell carcinoma, ovarian cancer, or esophageal cancer in one apiece. Of the 25 patients, 19 (79%) were of tumor stage IV and had extra-cranial metastasis. Eleven (44%) of the 25 primary cancers had a well-controlled status. Twelve patients (48%) had a Karnofsky Performance Scale (KPS) score of <70, and 13 (52%) were of Recursive Partitioning Analysis (RPA) class 3. Primary cancer status, RPA class, and functional status were found to be critical factors for consideration when selecting surgical candidates. In addition, adjuvant therapy was found to have an important role on survival.
