Purpose: In the present study, the difference in patients' nursing demands and nursing performance as perceived by the patients was examined. Methods: The participants were 272 patients on maintenance hemodialysis at five university hospitals. Nursing need and nursing performance were measured using the tool developed by Lee for this study. Results: The mean score for nursing demand was 3.35 points out of 4. The scores were higher for participants with middle school graduation or less, those not professing religion, and those whose medical insurance was of the medicaid type. The mean score for perceived nursing performance was 3.22 points out of 4. Nursing performance as perceived by hemodialysis patients was lower than nursing demand for 22 of 28 items. The item with the largest difference between nursing performance and nursing demand was 'Give a pain-free injection', followed by 'Explain about insurance benefits and supports' and 'Maintain quiet environment in the hemodialysis unit enabling rest during hemodialysis'. Conclusion: The results show that nursing performance as perceived by hemodialysis patients was lower than nursing demand. This result indicates a need to develop appropriate strategies to enhance nursing performance, especially for items that showed low nursing performance.

Dangguisu-san is a well-known traditional Korean herbal medicine prescription and has been widely used to treat ecchymosis, blood stagnation, and pain resulting from physical shock in Korea. In this study, an ultra-performance liquid chromatography-electrospray ionization-mass spectrometer method was established for the simultaneous determination of the 17 biomarker components in Dangguisu-san. All analytes were separated on an UPLC BEH $C_{18}$ ($100{\times}2.1$ mm, $1.7{\mu}m$) column and maintained at $45^{\circ}C$. The mobile phase consisted of two solvent systems, 0.1% (v/v) formic acid in water (A) and acetonitrile (B) by gradient flow. The injection volume was $2.0{\mu}l$ and the flow rate was 0.3 ml/min with detection at mass spectrometer. Calibration curves of the 17 biomarker components were acquired with $r^2$ values ${\geq}0.9951$. The values of limit of detection and quantification of all analytes were 0.02~6.32 ng/ml and 0.05~18.95 ng/ml, respectively. The amounts of the 17 components in Dangguisu-san sample were $3.17{\sim}13,224.50{\mu}g/g$.

Oxaliplatin, a third-generation platinum derivative, is the mainstay of current antineoplastic medications for advanced colorectal cancer therapy. However, peripheral neuropathic complications, especially cold allodynia, undermine the life-prolonging outcome of this anti-cancer agent. Rosavin, a phenylpropanoid derived originally from Rhodiola rosea, exhibits a wide range of therapeutic properties. The present study explored whether and how rosavin alleviates oxaliplatin-induced cold hypersensitivity in mice. In the acetone drop test, cold allodynia behavior was observed from days 3 to 5 after a single injection of oxaliplatin (6 mg/kg, i.p.). Cold allodynia was significantly attenuated following rosavin treatment (10 mg/kg, i.p.). Specific endogenous 5-HT depletion by three consecutive pretreatments with parachlorophenylalanine (150 mg/kg/day, i.p.) abolished the analgesic action of rosavin; this effect was not observed following pretreatment with naloxone (opioid receptor antagonist, 10 mg/kg, i.p.). Furthermore, 5-HT_1A receptor antagonist WAY-100635 (0.16 mg/kg, i.p.), but not 5-HT₃ receptor antagonist MDL-72222 (1 mg/kg, i.p.), blocked rosavin-induced analgesia. These results suggest that rosavin may provide a novel approach to alleviate oxaliplatin-induced cold allodynia by recruiting the activity of 5-HT_1A receptors.

Backgroud: Influenza vaccination is recommended for adults aged ${\geq}65$ years as they are at high risk of significant morbidity and mortality. This open-label, multicenter, post-marketing surveillance study assessed the safety of the MF59-adjuvanted trivalent inactivated subunit influenza vaccine, which is marketed as $FLUAD^{(R)}$ and $VANTAFLU^{(R)}$, in South Korean subjects aged ${\geq}65$ years. Materials and Methods: Solicited local and systemic adverse events (AEs) were collected from day 1 to 4 of the study. All unsolicited AEs and serious AEs (SAEs) were recorded from day 1 until study termination (day 29). Results: Of the 770 subjects enrolled ($FLUAD^{(R)}$, n = 389; $VANTAFLU^{(R)}$, n = 381), 39% overall experienced any solicited AE. Local AEs were reported by 33% of subjects overall; with the most common events being injection-site pain (30%) and tenderness (27%). Systemic AEs were reported by 19% of subjects overall with the most common events being myalgia (11%) and fatigue (8%). Conclusion: These results show that the MF59-adjuvanted influenza vaccine known as $FLUAD^{(R)}$ or $VANTAFLU^{(R)}$ had acceptable safety profiles in older adults (aged ${\geq}65$ years) in South Korea.

Factors such as location, volume, and the type of neoplasm complicate achieving tumor control. Electrochemotherapy (ECT) is a supplementary treatment for inoperable neoplasms in veterinary patients. Three dogs were diagnosed with a tumor. Two were squamous cell carcinoma (SCC), and the other was liposarcoma, each with a single tumor with the size range of 1 to 5 cm. The tumor locations were the cervical, oral, and abdominal cavity. ECT was selected as a treatment. Bleomycin was injected intratumorally at the dose of 0.5 to 1.0 mg/㎤. Five minutes after the injection, electric pulses applied in a sequence of eight pulses lasting 100 μsec each, were delivered in 1,000 V/cm. An evaluation was performed after 1 week, and the next session was administered 2 weeks later. In a patient with oral SCC, the tumor was in partial remission after two sessions of ECT. Another patient with SCC on her neck was showed complete remission after 2 weeks of ECT administration. A third patient showed stable disease for 8 weeks. Complications were mild and transient and included skin necrosis, edema, local pain, and gait disturbance. ECT is a valid adjuvant, especially for inoperable, cutaneous, or accessible intra-abdominal tumors.

Vincristine (VCR) is a chemotherapeutic agent widely used in treatment of malignancies. However, VCR has a limitation in use since it commonly causes a painful neuropathy (VCR-induced peripheral neuropathy, VIPN). Inflammatory cytokines secreted by immune cells such as macrophages can exacerbate allodynia and hyperalgesia, because inhibiting the inflammatory response is a treatment target for VIPN. In this study, we investigated whether Trichinella spiralis, a widely studied helminth for its immunomodulatory abilities, can alleviate VCR-induced allodynia. Von Frey test showed that T. spiralis infection improved mechanical allodynia at 10 days after VCR injection. We further observed whether the difference was due to mitigated axon degeneration, but no significant difference between the groups in axonal degeneration in sciatic nerves and intra-epidermal nerve fibers was found. Conversely, we observed that number of infiltrated macrophages was decreased in the sciatic nerves of the T. spiralis infected mice. Moreover, treatment of T. spiralis excretory-secretory products caused peritoneal macrophages to secrete decreased level of IL-1β. This study suggests that T. spiralis can relieve VCR-induced mechanical allodynia by suppressing neuroinflammation and that application of controllable degree of helminth may prove beneficial for VIPN treatment.

Several methods have been used to treat androgenetic hair loss, ranging from hair transplants to finasteride and minoxidil. Sometimes platelet-rich plasma injection therapy may be used to increase the satisfaction of patients who come to the hospital. However, some patients are sensitive to pain and are subjected to the inconvenience of requiring treatment after each blood sampling. The author had reported the effects of using a hair growth-promoting solution and Jetpeel^TM in parallel with a painless hair loss treatment method. However, the author was interested in more effective methods for patients with M-shaped or vertex hair loss who do not want to take medications or undergo hair transplant. In addition to the existing light-emitting diode therapy and electromagnetic field treatment, the author has made considered attempts to use various laser wavelength bands. However, the equipment for these methods can be expensive and are not suitable for patients who emphasize on cost-effectiveness. Therefore, the author used an existing reported method and a device based on the fractional erbium:YAG laser to provide the hair growth-promoting solution in parallel. The author chose a fractional 2940 nm-based laser device as a medium that could efficiently increase the growth phase, reduce the catagen phase, and facilitate intradermal product and drug delivery. As a result, there was a therapeutic benefit without any significant side effects such as redness and itching. Among the patients, the author reported the effects of the treatment on one patient with frontal M-shaped, mid, and vertex hair loss.

Background Carpal tunnel syndrome can be treated with corticosteroid injections (CIs) and surgery. In this systematic review, the influence of previous CI on different postoperative outcomes after carpal tunnel release is evaluated. Methods A systematic literature search using several databases was performed to include studies that examined patients diagnosed with carpal tunnel syndrome who received preoperative or intraoperative CIs. Results Of 2,459 articles, 9 were eligible for inclusion. Four papers reported outcomes of preoperative and four outcomes of intraoperative CIs. One study evaluated patients who received both intraoperative and preoperative corticosteroids. Conclusion Intraoperative CIs are associated with reduced postoperative pain after carpal tunnel release and support earlier recovery of the hand function that can be objectified in a faster median nerve conduction speed recovery and lower Boston Carpal Tunnel Questionnaire (BCTQ) scores. Using preoperative CIs did not lead to enhanced recovery after carpal tunnel release, and both preoperative and intraoperative CIs might be predisposing factors for infections.

Tarsal tunnel syndrome is a nerve entrapment syndrome of posterior tibial nerve as it passes through the tarsal tunnel. The patient presented posteromedial malleolar swelling, palpable mass and pain, and was misdiagnosed as ganglion cyst in the other clinic. Aspiration and steroid injection were done for years, which had no significant effect on symptom relief. As skin lesion and pigmentation abruptly appeared around the palpable mass, MRI and physical exam were done in our hospital. The patient was diagnosed as varicose veininduced tarsal tunnel syndrome and therefore tarsal tunnel decompression following dilatated varicose vein resection was done. The patient's symptom was improved after the surgery. Therefore, herein we report this case.
