Metaplastic breast cancer (MBC) is a rare type of breast carcinoma, characterized by various combinations of mesenchymal, adenocarcinoma and other epithelial components. MBC often manifests as a large mass, with low axillary lymph node involvement and poor prognosis. Knowledge and treatment patterns about MBC demographics, presentation and tumor characteristics are very limited. In clinical practice, MBC is usually treated based on the guidelines developed for infiltrating ductal carcinoma (IDC). The ideal treatment paradigm for MBC is unknown due to its low incidence and pathological variability, so potential predictors of treatment efficacy need to be explored. This review summarizes the current models and strategies for MBC according to the published literature.

A characteristic imaging finding in cases of methanol intoxication is putaminal necrosis, but its presence is usually not suspected due to its rarity. Methanol intoxication generally produces serious neurological symptoms that include visual disturbances and diminished consciousness, characteristically with metabolic acidosis. We reported the case of a 59-year-old man who was admitted to the hospital with diminished consciousness. Acute methanol intoxication was determined as the cause. Laboratory tests revealed high anion gap metabolic acidosis. Diffusion-weighted MRI indicated diffuse symmetric diffusion restriction lesions in the subcortical white matter of both cerebral hemispheres.

The incidence of contamination of epidural catheters used for pain control was investigated. To prevent epidural infection, all patients with epidural catheters had taken amoxacillin 1.5gm/day orally. Of the cultures of catheters catched from 303 patients undergoing continuous epidrual catheterization, 5 catheters (1.7%) were found to be contaminated; cervical 1/86 (1.2%), thoracic 1/27 (3.7%), and lumbar 3/190 (1.6%). Staphylococcus epidermidis was the most common etiologic agent (60%). To prevent epidural infection, sterilization of the skin around the epidural catheter and prophylactic use of broad-spectrum antibiotics are thought to be beneficial.

The burn center in our hospital is a national and regional (Southeast Asia) center. Of all admissions, 10% are related to blast explosions, and 8% due to chemical burns. In the acute burn management protocol of Singapore General Hospital, early surgical debridement is advocated for all acute partial-thickness burns. The aim of early surgical debridement is to remove all debris and unhealthy tissue, preventing wound infection and thereby expediting wound healing. In chemical burns, there can be stubborn eschars that are resistant to traditional debridement. We would like to present a novel technique using the diathermy scratch pad as a cheap and efficient tool for the dual purpose of surgical debridement and dermabrasion.

General PCR technique alone has a limitation for preimplantation genetic diagnosis(PGD) using single blastomere. Recntly developed primer extension preamplification(PEP) technology amplifies the whole genome and thus, simultaneous multiple locus analysis became possible. In this study, we report the efficacy of PEP-PCR for PGD in three muscular dystrophy carriers undergoing IVF-ET. A total of 37 blastomeres were obtained from 40 embryos at six to eight cell stage in three IVF cycles in two DMD and one BMD carriers. Whole genome from single blastomeres were amplified using I5-base oligonucleotide random primers. PCR amplified products of exon 45 in the dystrophin gene and alphoid X/Y loci for gender determination were analysed by 2% metaphor gel electrophoresis. A total of 37 PEP-PCR replicates from 37 single blastomeres from 40 embryos and 37 blanks were performed. We obtained the reliable results for exon 45 and alphoid X/Y. Transfer of female embryos and unaffected male embryo was attempted in three couples. Unfortunately, pregnancy was not achieved in these cases. PEP-PCR is a reliable and efficient PGD method in multiple locus analysis using single blastomere.

We report a case of 33-year-old man with a transient splenic uptake who had traumatic multiple rib fractures and hernoperitoneum combined with underlying liver cirrhosis, liver cirrhosis with liver bed laceration and splenomegaly without any other demonstrable splenic lesion due to traffic accident was found by abdominal ultrasound and surgery. Incidentally, $^{99m}Tc$-MDP Bone scan showed whole prominent splenic uptake, spleen was also visible on $^{99m}Tc$ Tin colloid liver scan. We suggest the splenic uptake of the radionuclide temporary splenic infarct to the transient total splenic infarction or unknown traumatic effect.

Lung cancer seriously threatens human health, so it is important to investigate gene expression changes in affected individuals in comparison with healthy people. Here we compared the gene expression profiles between smokers with and without lung cancer. We found that the majority of the expressed genes (threshold was set as 0.1 RPKM) were the same in the two samples, with a small portion of the remainder being unique to smokers with and without lung cancer. Expression distribution patterns showed that most of the genes in smokers with and without lung cancer are expressed at low or moderate levels. We also found that the expression levels of the genes in smokers with lung cancer were lower than in smokers without lung cancer in general. Then we detected 27 differentially expressed genes in smokers with versus without lung cancer, and these differentially expressed genes were foudn to be involved in diverse processes. Our study provided detail expression profiles and expression changes between smokers with and without lung cancer.

Primary spinal cord lymphomas are rare, and are either extra-/intradural masses with leptomeningeal infiltration or intramedullary in nature. The authors present a patient with a diffuse large B-cell lymphoma involving the sacral nerve root, extension to extradural space, and the cranial nerve.
