Background/Aims: The invasiveness of a liver biopsy and its inconsistent results have prompted efforts to develop noninvasive tools to evaluate the severity of chronic hepatitis. This study was intended to assess the performance of serum biomarkers for predicting liver fibrosis in patients with chronic viral hepatitis. Methods: A total of 302 patients with chronic hepatitis B or C, who had undergone liver biopsy, were retrospectively enrolled. We investigated the diagnostic accuracy of several clinical factors for predicting advanced fibrosis (F≥3)...

Importance: Computed tomography-derived fractional flow reserve (FFR-CT) is a novel, noninvasive test for myocardial ischemia. Clinicians using FFR-CT must be able to interpret individual FFR-CT results to determine subsequent patient care. Objective: To provide clinicians a means of interpreting individual FFR-CT results with respect to the range of invasive FFRs that this interpretation might likely represent. Evidence Review: We performed a systematic review in accordance with guidelines from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses...

Importance: The current staging system of gastric cancer is not adequate for defining a prognosis and predicting the patients most likely to benefit from chemotherapy. Objective: To construct a survival prediction model based on specific tumor and patient characteristics that enables individualized predictions of the net survival benefit of adjuvant chemotherapy for patients with stage II or stage III gastric cancer. Design, Setting, and Participants: In this multicenter retrospective analysis, a survival prediction model was constructed using data from a training cohort of 746 patients with stage II or stage III gastric cancer who satisfied the study's inclusion criteria and underwent surgery between January 1, 2004, and December 31, 2012, at Nanfang Hospital in Guangzhou, China...

Vulvar cancer accounts for less than 1% of malignancies in women. Verrucous carcinoma of the vulva is a rare histological variation, comprising less than 1% of vulvar cancer cases. Although it is characterized as being locally invasive, the condition is not associated with metastatic spreading. Lesions present in the form of a verrucous, ulcerated, and bleeding tumor that can reach large dimensions. This type of tumor can be mistaken for condylomata, both macroscopically and microscopically. We report the case of an 81-year-old patient with a large vulvar tumor presented for eight years, initially considered as a Buschke-Löwenstein tumor...

Ductal eccrine carcinoma (DEC) is a rare sweat gland carcinoma with ductular differentiation. Clinically, it is characterized by a slowly growing, hardened plaque or nodule predominantly located on the head and neck. Histologically, DEC shares similar features to invasive breast carcinoma, thus causing great diagnostic challenges. We report a 69-year-old woman who presented with a hardened plaque on the axilla. A skin biopsy was performed and metastatic invasive breast carcinoma could not be ruled out. Complete excision and further workup were subsequently conducted, leading to the diagnosis of estrogen receptor positive DEC with associated axillary lymph node metastases...

Y Zhang, Q Chen
Ovarian cancer is one of the most malignant genital cancers, with a high mortality rate. Many researchers have suggested that matrix metalloproteinases (MMPs) have remarkably high expression in ovarian cancer tissues. MMPs are considered to be related to the occurrence, development, invasion and metastasis of ovarian cancer. Moreover, some studies have discovered that the unbalance between MMPs and tissue inhibitor of metalloproteinases (TIMPs) are associated with the malignant phenotype of tumors. This review summarizes the latest research progress of MMPs in ovarian cancer...

BACKGROUND The abdominal straining pattern can act as a novel parameter for improving the prediction of bladder outlet obstruction (BOO). To preserve detrusor function in the early stage of urinary system impairment, such as BOO, we establish a novel method for cystometry and Intra-abdominal pressure (IAP) assessments in rodents without cystostomy. MATERIAL AND METHODS Twenty mice and rats were divided into three groups (control, sham-operated and BOO group) respectively. The cystometry and IAP assessments were measured by the pediatric venous indwelling sheath and coronary dilatation catheter connected to Laborie urodynamic system on postoperative day 7...

REVIEW

Early diagnosis and prompt initiation of appropriate antimicrobial therapy are crucial steps in the management of patients with invasive fungal infections. However, the diagnosis of invasive mycoses remains a major challenge in clinical practice, because presenting symptoms may be subtle and non-invasive diagnostic assays often lack sensitivity and specificity. Diagnosis is often expressed on a scale of probability (proven, probable and possible) based on a constellation of imaging findings, microbiological tools and histopathology, as there is no stand-alone assay for diagnosis...

REVIEW
Katie E Gilligan, Róisín M Dwyer
There remains an urgent need for novel therapeutic strategies to treat metastatic cancer, which results in over 8 million deaths annually worldwide. Following secretion, exosomes are naturally taken up by cells, and capable of the stable transfer of drugs, therapeutic microRNAs and proteins. As knowledge of the biogenesis, release and uptake of exosomes continues to evolve, and thus also has interest in these extracellular vesicles as potential tumor-targeted vehicles for cancer therapy. The ability to engineer exosome content and migratory itinerary holds tremendous promise...

Pterygium is a vascularized, invasive transformation on the anterior corneal surface that can be treated by Strontium-/Yttrium90 beta irradiation. Finite element modeling was used to analyze the biomechanical effects governing the treatment, and to help understand clinically observed changes in corneal astigmatism. Results suggested that irradiation-induced pulling forces on the anterior corneal surface can cause astigmatism, as well as central corneal flattening. Finite element modeling of corneal biomechanics closely predicted the postoperative corneal surface (astigmatism error -0...

REVIEW
Hye-Kyung Na, Ja Young Lee
Many meta-analysis, large cohort studies, and experimental studies suggest that chronic alcohol consumption increases the risk of gastric and colon cancer. Ethanol is metabolized by alcohol dehydrogenases (ADH), catalase or cytochrome P450 2E1 (CYP2E1) to acetaldehyde, which is then further oxidized to acetate by aldehyde dehydrogenase (ALDH). Acetaldehyde has been classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen to humans. The acetaldehyde level in the stomach and colon is locally influenced by gastric colonization by Helicobacter pylori or colonic microbes, as well as polymorphisms in the genes encoding tissue alcohol metabolizing enzymes, especially ALDH2...

STUDY DESIGN: Retrospective cohort study OBJECTIVE.: To determine the independent effects of operative time and surgical invasiveness on perioperative outcomes after posterior spinal fusions for adult spinal deformity. SUMMARY OF BACKGROUND DATA: Morbidity is high after posterior fusions for adult spinal deformity. While previous reports have demonstrated an association between perioperative outcomes and the extent of correction and fusion (number of posterior levels fused, pelvic fixation, combined anterior-posterior fusion), no study has looked at the independent effects of the surgical invasiveness after controlling for operative time...

BACKGROUND: Fat grafting has been widely indicated for postmastectomy and postlumpectomy breast reconstruction. The literature emphasizes the clinical efficacy of fat grafting, but experimental studies raise important questions about the recurrence risk because of the stimulation of remaining cancer cells by progenitor or adult adipocytes. Because breast conservative treatment provides a higher risk of residual cancer cells in the breast tissue compared with mastectomy, the authors set up a matched case-control study of fat grafting versus no fat grafting after breast conservative treatment...

BACKGROUND: Patients with sickle cell disease (SCD) are at risk of fatal sepsis with encapsulated bacteria, such as Streptococcus pneumoniae, because of the inherent autosplenectomy that occurs in SCD. This risk is thwarted with oral penicillin prophylaxis during the first 5 years of life, and with stringent vaccination against S. pneumoniae alongside routine childhood immunization. But compared with the general African American pediatric population, the rate of invasive pneumococcal disease (IPD) in patients with SCD still remains high, resulting in hospitalization and fatality...

Hysterectomy is one of the most frequently performed surgical procedures in the United States. Selection of the route of hysterectomy for benign causes can be influenced by the size and shape of the vagina and uterus; accessibility to the uterus; extent of extrauterine disease; the need for concurrent procedures; surgeon training and experience; average case volume; available hospital technology, devices, and support; whether the case is emergent or scheduled; and preference of the informed patient. Vaginal and laparoscopic procedures are considered "minimally invasive" surgical approaches because they do not require a large abdominal incision and, thus, typically are associated with shortened hospitalization and postoperative recovery times compared with open abdominal hysterectomy...
