We report a case of pityriasis versicolor atrophicans in a 20-year-old woman who presented with chronic multiple brownish atrophic macules and patches on chest and back. The lesions had developed six years ago and the patient had used topical medication including steroid ointments for the last two years prior to visiting our clinic. KOH examination was positive, so skin biopsy was performed and the diagnosis of pityriasis versicolor atrophicans was made. Since our patient had applied topical steroids for some time, it was difficult to rule out steroid-induced atrophy in a common tinea versicolor. Also, differential diagnosis was performed with respect to other skin diseases manifesting with cutaneous atrophy including anetoderma.

Rowell's syndrome is a rare entity consisting of lupus erythematosus with associated erythema multiforme-like lesions and characteristic immunological findings, and it was first described by Rowell et al. in 1963. Because of the clinical similarities between subacute cutaneous lupus erythematosus and Rowell's syndrome, it is difficult to clinically distinguish between the annular-polycyclic type of subacute cutaneous lupus erythematosus and Rowell's syndrome. We report a case of 18-year-old woman with systemic lupus erythematosus who presented erythema multiforme-like eruptions on both thighs. Simultaneously, she developed urticarial-like rashes on her trunk consistent with atypical skin lesion of lupus erythematosus. She also developed a positive antinuclear antibody with speckled pattern and positive anti-Ro antibody.

Background and Objectives:
O-cyclic phytosphingosine-1-phosphate (cP1P) is a synthetic chemical and has a structure like sphingosine-1-phosphate (S1P). S1P is known to promote cell migration, invasion, proliferation, and anti-apoptosis through hippocampal signals. However, S1P mediated cellular-, molecular mechanism is still remained in the lung.Acute lung injury (ALI) and its severe form acute respiratory distress syndrome (ARDS) are characterized by excessive immune response, increased vascular permeability, alveolar-peritoneal barrier collapse, and edema. In this study, we determined whether cP1P primed human dermal derived mesenchymal stem cells (hdMSCs) ameliorate lung injury and its therapeutic pathway in ALI mice.
Methods:
and Results: cP1P treatment significantly stimulated MSC migration and invasion ability. In cytokine array, secretion of vascular-related factors was increased in cP1P primed hdMSCs (hdMSCcP1P ), and cP1P treatment induced inhibition of Lats while increased phosphorylation of Yap. We next determined whether hdMSCcP1P reduce inflammatory response in LPS exposed mice. hdMSCcP1P further decreased infiltration of macrophage and neutrophil, and release of TNF-α, IL-1β, and IL-6 were reduced rather than naïve hdMSC treatment. In addition, phosphorylation of STAT1 and expression of iNOS were significantly decreased in the lungs of MSCcP1P treated mice.
Conclusions
Taken together, these data suggest that cP1P treatment enhances hdMSC migration in regulation of Hippo signaling and MSCcP1P provide a therapeutic potential for ALI/ARDS treatment.

A Pancreaticobiliary fistula is a rare complication of acute necrotizing pancreatitis or pancreatic abscess. One case is herein reported of pancreaticobiliary fistula that was found following removal of pancreatic duct stones by extracorporeal shock-wave lithotripsy and endoscopic sphincterotomy. The patient was a 53-year old woman who was admitted with epigastric pain and fever. Endoscopic retrograde pancreatography revealed multiple stones in the main pancreatic duct. Pus from the pancreatic duct was drained through the major papilla during cannulation. On balloon cholangiogram obtained after removal of the stones, a direct fistulous connection between the main pancreatic duct and distal common bile duct was noted. It is speculated that pancreatic abscess or mechanical compression of pancreatic duct stones may contribute to the destruction of the intrapancreatic bile duct, which leads to the formation of a pancreaticobiliary fistula.

BACKGROUND:
Acinetobacter baumannii infection is a significant health problem worldwide due to increased drug resistance. The limited antimicrobial alternatives for the treatment of severe infections by multidrug-resistant A. baumannii (MDRAB) make the search for other therapeutic options more urgent. Linalool, the major oil compound in Coriandrum sativum, was recently found to have high antibacterial activity against A. baumannii. The purpose of this study was to investigate the synergistic effect of linalool and colistin combinations against MDRAB and extensively drug-resistant A. baumannii (XDRAB).
METHODS:
A total of 51 strains of A. baumannii clinical isolates, consisting of 10 MDRAB and 41 XDRAB were tested. We determined the minimum inhibitory concentration (MIC) of linalool for the test strains using the broth microdilution method and searched for interactions using the time-kill assay.
RESULTS:
The time-kill assay showed that the linalool and colistin combination displayed a high rate of synergy (92.1%) (by synergy criteria 2), low rate of indifference (7.8%), and a high rate of bactericidal activity (74.5%) in the 51 clinical isolates of A. baumannii. The synergy rates for the linalool and colistin combination against MDRAB and XDRAB were 96% and 92.1%, respectively. No antagonism was observed for the linalool and colistin combination.
CONCLUSION
The combination of linalool and colistin showed a high synergy rate, which may be beneficial for controlling MDRAB infections. Therefore, this combination is a good candidate for in vivo studies to assess its efficacy in the treatment of MDRAB infections.
