A 47-year-old woman ingested about 12 mg of colchicine with suicidal intent. Colchicine, a highly poisonous alkaloid, is a commonly used treatment for gout, Bechet's disease, and familial Mediterranean fever. Despite the knowledge of its side effects, the risk of a significant overdose is under-appreciated. She suffered from acute multisystem toxicity, including gastrointestinal disorders, bone marrow suppression, alopecia, and probable pancreatitis, but she ultimately recovered with supportive therapy. We report a case of acute colchicine toxicity from a single overdose with a review of the literature.

Some canine typical Sertoli cell tumors (SCT) induce signs of hyperestrinism. However, whether variant lipid-rich SCTs have signs of hyperestrinism remains largely unknown. In the present study, an 11-year-old male Pekingese dog showed significantly elevated serum estrogen and characteristic signs of hyperestrinism such as gynecomastia and alopecia. Cytological, radiological and ultrasound examinations found testicular mass, prostatitis with squamous metaplasia, and cystitis. Pathologically, the tumor lesions consisted mainly of lipid-rich tumor cells with signet-ring appearance, which were immunohistochemically positive for vimentin and anti-$M{\ddot{u}}llerian$ hormone. Based on the findings, a diagnosis of lipid-rich Sertoli cell tumor was established. In conclusion, a canine lipid-rich SCT induced signs of hyperestrinism and caused prostatitis via squamous metaplasia due to its excessive secretion of estrogen.

The cyclin-dependent kinases (CDKs), a group of serine/threonine kinases that form active heterodimeric complexes binding to cyclins, are key regulators of the cell cycle. The role of cyclin dependent kinases(CDKs) in cell cycle regulation has stimulated an interest in them as potential targets for proliferative diseases such as cancer, psoriasis, and chemotherapeutic agent-induced alopecia. Indirubin, an active ingredient of a traditional Chinese recipe Danggui Longhui Wan, are potent CDK inhibitors competing with ATP for binding to the catalytic site of the CDKs. (omitted)

A 12-year-old neutered male Maltese was brought to our hospital with loss of appetite, generalized alopecia, anemia, and a palpable abdominal mass. Ultrasonography revealed multiple abdominal masses in the liver and spleen. Subsequently, splenectomy and liver biopsy were performed, and the masses were histologically diagnosed as metastatic fibrosarcomas of unknown primary origin. The owner refused further investigations such as computed tomography and hepatectomy, therefore, we decided to initiate chemotherapy in the form of metronomic therapy with toceranib phosphate, which has several advantages, such as better tolerability, low cost, and convenience. The size and number of hepatic fibrosarcomas continued to increase despite continued administration of toceranib (10 mg/dog, PO, q48h). The dog died approximately 43 days after initiation of the toceranib treatment. To the best of our knowledge, this is the first report on toceranib therapy for metastatic hepatic fibrosarcoma in a dog.

Identifying tumors or wounds on the scalp is difficult because hair blocks the vision during surgery and suturing. In the meantime, we have commonly used hairpins to hold the hair for a clearer view; however, we would like to suggest a new method, a "hair-fixing sheet," consisting of hook-like surface. We applied the two methods, hair-fixing sheets and hairpins, assuming several situations. In these situations, it was possible to fix a wider range or various shapes more conveniently using a hair-fixing sheet than using several hairpins at a similarly low cost. In addition, it was easy to change the hair to be fixed, remove it postoperatively, and prevent the hair from being pulled out, thereby preventing additional postoperative pain.

Cronkhite-Canada syndrome is a rare gastrointestinal polyposis syndrome with distinctive clinical features and endoscopic findings. Diagnosis can be challenging without suspicion, and the disease carries high mortality due to complications such as infection, gastrointestinal bleeding, and malignancies. This paper presents two cases of Cronkhite-Canada syndrome occurring after coronavirus disease 2019 (COVID-19) mRNA vaccination. Both cases exhibited typical clinical findings, including hypogeusia, onychodystrophy, alopecia, and weight loss. Typical polyposis in the gastrointestinal tract was confirmed through endoscopies. As symptomatic treatment did not improve the symptoms, corticosteroids were administered, and symptoms and laboratory test results improved immediately. The patients improved upon corticosteroids tapering. These cases illustrate typical presentations of Cronkhite-Canada syndrome and the course of the disease following corticosteroid treatment. Additionally, they suggest the possibility that Cronkhite-Canada syndrome may be triggered by COVID-19 mRNA vaccination.

Biotae Orientalis has been widely used for treatment of relaxion of smooth muscle, gastrointestinal hemorrhage and alopecia in Oriental Medicine. This experiment examined the effect of an extracts, obtained from the acetone and MeOH extracts of dried or fresh Biotae Orientalis, on hair growing activity of the C57BL/6N mice after topical application to skin. First, We examined on hair growth activity of extracts of Biotae Orientalis compare to control and 1% minoxidil groups. Second, We investigated on the number of hair follicle and mast cells after topical application of extracts of the Biotae Orientalis to skin for 16 day. Third, We investigated immunoreactive density of vascular endothelial growth factor(VEGF), protein kinase C-${\alpha}$(PKC-${\alpha}$) and stem(mast) cell factor(SCF) in skin of C57BL/6N mice by immunohistochemical methods. I fourth investigated changes of subpopulation of splenocytes and thymocytes in C57BL/6N mice for 16day using laser flow cytometry. The results were as follows : Hair growing effect of acetone and MeOH extracts of dried and fresh Biotae Orientalis was observed in 70%, 90% and 60% in hair removed skin area in 16 day respectively. Immunoreactive density of VEGF and PKC-${\alpha}$ in skin of experimental groups was weakly stained compare to control group in 10 day. Immunoreactive density of stem cell factor in skin of experimental group was heavily stained compare to control group in 10 day. Splenic TH/TC Iymphocytes of lived MeOH extracts group significantly increased compare to control group. TH cells in thymic T lymphocytes were increased compare to control group. These experiment suggest that acetone and MeOH extracts of Biotae Orientalis may be used for topical treatment of alopecia areata.

Background: To study the response rate, toxicity profiles, and survival of refractory or recurrent epithelial ovarian cancer (EOC) patients treated with paclitaxel. Materials and Methods: Patients with refractory or recurrent EOC who were treated with paclitaxel between January 2002 and December 2011 at the Department of Obstetrics and Gynecology, Faculty of Medicine, Vajira Hospital were identified. Clinicopathological features of the patients including detailed data of paclitaxel treatment were collected. Results: During the study period, a total of 44 patients were identified, with a mean age of $52.9{\pm}8.2$ years. Some 13.6% (six patients) had refractory cancer to first-line chemotherapy while 86.4% (38 patients) had recurrent cancer. Among these, 35 (79.6%) and 9 (20.4%) patients were considered as platinum-sensitive and platinum-resistant, respectively. Three patients (6.8%) received fewer than 2 cycles of paclitaxel due to loss to follow-up, leaving 41 patients evaluable for response. The overall response rate observed in all 41 patients was 41.5% (17 patients; 12 complete and five partial responses): 12.5% or 1/8 patients with refractory or platinum-resistant cancer and 48.5% or 16/33 patients with platinum-sensitive disease. Stable disease was demonstrated in 17.0% (seven patients) while progressive disease was apparent in 41.5% (17 patients). Median time to progress was 4.5 months (range, 0.67-58.6 months). Median progression-free survival was not reached while median overall survival was 16.3 months (95% confidence interval, 11.0 months -21.6 months). Common toxicities were neutropenia, neuropathy, and alopecia. Conclusions: Paclitaxel is an active agent for refractory or recurrent EOC. Neutropenia, neuropathy and alopecia are common side effects.

Bonogen shampoo is composed of several plant extracts which are known to be used in oriental medicine. This study was carried out to investigate the effects of Bonogen shampoo on hair growth in an alopecia model of C57BL/6 mice. There were eight male and female experimental groups including distilled water(DW: negative control), a commercial shampoo[M], 3% minoxidil (MXD) and Bonogen shampoo(BNG). Dorsal skin hair of six-week-old mice was trimmed with an electric clipper carefully not to damage the skin. The next day, mice without skin scratch were selected, randomized and separated in 10 mice per group. The test compounds were topically treated with 0.15 ml per mouse or dorsal skin for 21 days daily and then washed thoroughly with DW. The hair regrowth was determined photographically at 0, 4, 7, 10, 15, 18, and 21 days and histologically at day 21. No clinical signs were observed in all mice. Although body weight was slightly increased in 3% MXD group than other groups, it was not significant. Hair regrowth began to be promoted after 14 days and appeared a distinct regrowth pattern in all animals by topical treatment of test compounds at 18 days. In particular, the topical treatment of bonogen shampoo or 3% MXD for 21 days to dorsal skin accelerated hair regrowth faster than DW or M shampoo. At 21 days, the hair regrowth promotion speed was in order of 3% MXD>BNG>M>DW. The bonogen shampoo or 3% MXD also promoted hair follicle elongation compared to the negative control. These results suggest that bonogen shampoo has hair growth promoting activities and may be useful for treatment of bald or alopecia.
