A case analysis of a patient with salmonella infection and allergy to antibiotics / 药学实践杂志

Objective Through clinical pharmacists participating in the treatment of hip prosthesis infection, to explore the factors of Salmonella infection and skin itching, and to increase the importance of Salmonella infection and the pharmaceutical monitoring of adverse reactions of antibiotics. Methods The causes and treatment of Salmonella infection were analyzed by reviewing the literature, monitoring indicators and patient's clinical symptoms, and analyzing the cause of the patient's skin itching, to provide the patient with a reasonable anti-infective treatment plan. Results After several antibacterial drug adjustments during hospitalization, the patient's inflammatory indicators decreased, and the clinical symptoms improved. Conclusion Although the prosthetic joint infection caused by Salmonella is very rare, attention should be paid to the detection of Salmonella. At the same time, clinical pharmacists should increase the monitoring of antibiotics in their daily work.

Skin itching is a subjective sensation that causes the desire to scratch. It is one of the most common clinical symptoms at department of dermatology, even the only complaint of dermatological patients, which seriously affects the quality life of patients. Therefore, based on the software of traditional Chinese medicine inheritance auxiliary platform, association rules and complex system entropy clustering were adopted to collect and analyze Zhang Bing's prescriptions for skin itching, and get the drug use frequency and the relationship between drugs. Based on that, we could conclude the experience for skin itching. A total of 147 prescriptions were collected, 20 drugs with a frequency of 34 or more and 20 high-frequency drug combinations were analyzed, and 14 core combinations and 7 new prescriptions were excavated. The high-frequency drugs included Kochiae Fructus, Dictamni Cortex, Mori Cortex. The high-frequency drug combinations included "Kochiae Fructus-Dictamni Cortex" "Angelicae Dahuricae Radix-Chuanxiong Rhizoma" "Paeoniae Radix Rubra-Paeoniae Radix Alba", and the core combinations included "Schizonepetae Herba-Saposhnikoviae Radix-Cinnamomi Ramulus" "Arctii Fructus-Cicadae Periostracum-Houttuyniae Herba" "Ghrysanthemi Indici Flos-Kochiae Fructus-Dictamni Cortex", and new formulations include "Schizonepetae Herba, Saposhnikoviae Radix, Cinnamomi Ramulus, Clematidis Radix et Rhizoma, Tribuli Fructus, Dictamni Cortex", "Phellodendri Chinensis Coritex, Lonicerae Japonicae Flos, Atractylodis Rhizoma, Ghrysanthemi Indici Flos, Kochiae Fructus, Dictamni Cortex" "Arctii Fructus, Cicadae Periostracum, Houttuyniae Herba, Trichosanthis Fructus". The result of this research shows that Professor Zhang Bing's experience in the treatment of skin itching is mainly to dispelling wind and arresting itching, clearing heat and drying dampness.

Inhibition of TRPV1 prevented skin irritancy induced by phenoxyethanol. A preliminary in vitro and in vivo study.

BACKGROUND: Phenoxyethanol is a widely used preservative in personal care products. Transient receptor potential vanilloid 1 (TRPV1) on cell membrane is activated by TRPV1 agonist capsaicin resulting in an opening of the channel for calcium influx, which is linked with neurosensory sensations characterized by itching, burning and stinging of skin. Whether uncomfortable skin sensations caused by phenoxyethanol claimed by people having sensitive skin are also due to activation of TRPV1 has not been reported in the literature. OBJECTIVE: The aim of this study was to evaluate whether the TRPV1 is involved in the induction of itching and burning sensation by phenoxyethanol. METHODS AND MATERIALS: The effect of phenoxyethanol on TRPV1 was assessed in vitro on HaCaT cells. The activation of TRPV1 and its inhibition by a TRPV1 antagonist were evaluated by cellular calcium influx. TRPV1 protein expression was also investigated by Western blot. In vivo in a split-face study, phenoxyethanol formulated at 1% was compared to a formulation additionally containing a TRPV1 antagonist. By applying the formulations to the nasolabial fold, the scores of phenoxyethanol-induced sensations were compared to those of the TRPV1 antagonist. RESULTS: In vitro phenoxyethanol induced calcium influx in HaCaT cells in a dose-dependent manner after 20 min. This effect was abolished by a solution containing the TRPV1 antagonist trans-tert-butyl cyclohexanol (ID1609). Phenoxyethanol had no effect on the expression of TRPV1, whereas capsaicin caused a significant downregulation of this receptor in the same experiment. In vivo 1% phenoxyethanol induced a skin burning and itching sensation in a cohort of 60 of 243 Chinese female subjects being sensitive to phenoxyethanol discomfort. The uncomfortable skin sensations were significantly inhibited by ID1609. CONCLUSIONS: Different to capsaicin, phenoxyethanol did not downregulate the expression of TRPV1 in HaCaT cells, suggesting that different regulatory mechanisms may exist for capsaicin and phenoxyethanol. Our experiments demonstrated that phenoxyethanol induces skin misperception and uncomfortable skin sensations like itching and burning comparable to capsaicin via activating TRPV1. The stimulation was inhibited by blocking TRPV1 with ID1609. The present data strengthened hitherto studies that TRPV1 plays a critical role in sensitive skin.
