A 59-year-old man, immunosuppressed after renal transplant, presented with a painful posterior thigh mass concerning for malignancy, as well as pulmonary and posterior chest wall nodules. Cultures and mass spectrometry identified Nocardia paucivorans. The patient underwent operative irrigation and debridement of the posterior thigh and chest wall, with 12 months of antibiotic therapy.

A 2-week delay in appropriate treatment was due to low suspicion for infectious etiology. Since cultures generally take weeks for positive diagnosis, advanced molecular or biochemical methods should be used. This case demonstrates importance in maintaining a high index of suspicion for nocardiosis in immunocompromised patients with soft-tissue masses.

The common peroneal nerve (CPN) is one of the most frequently injured nerves of the lower extremity.

One-third of patients who develop CPN palsy proceed to chronic impairment without signs of recovery.

Ankle-foot orthoses can provide improvement with respect to gait dysfunction and are useful as a nonsurgical treatment option.

Severe cases of CPN palsy demonstrating no signs of recovery may require operative intervention with tendon transfer.

This study compared the allergen sensitivity in four southern China cities. We enrolled 55,432 participants (27,408 male, 28,024 female) between 2007 and 2019. The allergen-specific IgE levels were compared by the χ2 test. The five prevalent sensitivities were for mite mix (10,985, 19.82%), cockroach (4,860, 8.77%), crab (4,450, 8.03%), fish mix (3,874, 6.99%), and house dust (3,486, 6.29%). Almost all allergen sensitivities decreased with age, particularly from infant to middle aged participants (p less then 0.05). An exception was Shenzhen, where food allergen positive rates remained constant in all age groups studied. The proportion of male sensitive to at least one food allergen (OR 1.130; 95% CI 1.088-1.174, p less then 0.0025) or aeroallergen (OR, 1.117; 95% CI, 1.078-1.158, p less then 0.0025) was higher than female in all four cities. Except for dog dander and tree mix, all aeroallergens differed significantly between seasons (p less then 0.05). Liuzhou had the highest rates of food allergen- and aeroallergen-positive participants. The allergen-specific IgE distribution differed among the studied cities, with significant seasonal differences. Young age, male sex, and aeroallergens were risk factors for allergic disease.Research on association between programmed cell death ligand 1 (PD-L1) expression in cancer cells and prognosis of esophageal squamous cell carcinoma (ESCC) has been controversial and has focused on patients with surgical resection. We aimed to investigate impact of PD-L1 on treatment response and prognostic value in ESCC and analyze which subset of patients may benefit from immunotherapy. The PD-L1 expression was evaluated by immunohistochemical analysis in all patients. Stratification analysis was performed according to whether surgery was performed. There were no significant correlations between PD-L1 expression with 3-year overall survival (OS) and progression-free survival (PFS) in 81 ESCC patients. Then stratification analysis was performed. Among these 44 patients without surgery, disease control rate (DCR) in negative PD-L1 expression group (78%) was significantly better than those (42%) in positive PD-L1 expression group (P = 0.032). There were no significant correlations between PD-L1 expression with 3-year OS and PFS in 37 ESCC patients receiving surgery. However, in 44 ESCC patients without surgery, the Kaplan-Meier method showed that 3-year OS and PFS in negative PD-L1 expression group were significantly better than those in positive PD-L1 expression group. In Cox univariate and multivariate model, PD-L1 was an independent prognosticator for inferior OS (p = 0.011; p = 0.017). Our research revealed prognostic role of PD-L1 expression in cancer cells may be variable in different treatment methods. Consequently, PD-L1 may serve as an independent prognostic factor and provide a theoretical basis for combining conventional therapy with immunotherapy targeting PD-L1 to achieve better treatment outcome in ESCC patients without esophagectomy.The objective of this study was to investigate the stability of compounded nifedipine cream in gel and ointment formulations dispensed in white plastic and glass amber jars. Extemporaneously compounded nifedipine cream (Glaxal Base), gel (K-Y Jelly), and ointment (Aquaphor) in white plastic and glass amber jars were stored at 4°C, 23°C, and 40°C. We determined potency on days 0, 7, 14, 30, 60, and 90, and subsequently assigned beyond-use-dates based on United States Pharmacopeia recommendations, organoleptic properties, and pH changes. Nifedipine potency in cream and ointment stored in white plastic jars was within ±10% of initial for 90 days (excluding day 14 for cream). In glass amber jars, potency was outside the acceptable range by day 14 at 23°C but within range for 90 days at 4°C (excluding day 30). Nifedipine potency was maintained for 90 days in both jars at 23°C and 4°C (excluding day 30) and in white plastic jars at 40°C, but 60 days stored in glass amber jars. The pH of formulations was stable with changes of less than 1-unit pH. At 40°C, a significant decrease in apparent viscosity of cream was evident on day 90. There was a decrease in apparent viscosity and phase separation of the ointment at 40°C and an increase in apparent viscosity (difficult to mix) at 4°C on day 14 onwards. Significant organoleptic changes were observed by day 7 at 40°C (decrease in apparent viscosity and abnormal odor by day 90), day 30 at 4°C (thicker consistency), and day 90 at 23°C (abnormal odor). Storage in white plastic jars at 23°C is recommended for compounded topical nifedipine cream and ointment (for 90 days), and for gel (60 days).In this work, we focus on three ready-to-use vehicles Fitalite, Versatile, and HRT Supreme Cream Base. Fitalite is a natural, light, hydrophilic gel-cream that contains vitamin E and oil bodies from plant sources (phytosomes), providing antioxidant and skinmoisturizing properties. Versatile is a vanishing oil-inwater cream base which retains its consistency with a broad range and high concentrations of active pharmaceutical ingredients, dermaceutical ingredients, and solvents. Finally, HRT Supreme Cream Base is a paraben-free, dye-free, fragrance-free O/W emulsion base, formulated with a complex of botanical oils to soothe and provide moisture to dry and sensitive skin. In the current study, we evaluated the beyond-use date of formulations containing estradiol, estriol, estrone, progesterone, and testosterone in combination, compounded with these three vehicles. Validated, stability-indicating high-performance liquid chromatography methods were used throughout a 180-day period. A beyond-use date of 180 days was observed for all vehicles stored both at refrigerated and at room temperature. The combination of five ingredients represents a worst-case scenario since there are more possibilities of cross reactions. Therefore, we expect the same or greater stability as individual ingredients are removed from the tested formulation. The extended beyond-use dates provide convenience for both the compounding pharmacist and the patient.Dexmedetomidine is a sedative medication with co-analgesic effects that has been used primarily in critical care and anesthesia as a continuous intravenous infusion. Its utility in the treatment of refractory agitated delirium is being investigated in other settings including palliative care, but continuous intravenous infusions are not always feasible during end-of-life care. Subcutaneous infusions are more commonly used in this setting, but smaller volumes and higher concentrations are typically required. Investigations into stability at these higher concentrations are required to address preparation and administration feasibility issues. The objective of this research was to study the chemical stability of high-concentration dexmedetomidine 20 mcg/mL prepared in polyvinyl chloride bags with 0.9% sodium chloride and storage up to 9 days under refrigeration and room temperature conditions. A total of four solutions of dexmedetomidine 20 mcg/mL in 0.9% sodium chloride were prepared in polyvinyl chloride bags om temperature.The compounding of intravenous admixtures requires knowledge of the packaging and container-closure issues, including their composition, physicochemical characteristics, and tendency towards producing particulates as well as sorption issues. In this article, we will look at containers, closure systems, and sorption issues related to compatibility and stability. Part 11 of this series will discuss particulates in intravenous admixtures.The selection of a rectal suppository base can be critical for proper compounding, storage, administration, and release of the drug for the patient. In this article, a number of different characteristics are discussed, as well as potential compatibility and stability issues. Also, a number of example bases are presented and discussed.Container closure integrity provides assurance that compounded sterile preparation quality attributes are met throughout its shelf life. Since compounded sterile preparations lacking container-closure integrity are considered adulterated as per the Federal Food, Drug and Cosmetic Act and are therefore unsafe for patient use, compounders must be able to produce a well-closed sealed vial. Furthermore, 503B outsourcing facilities must qualify the capping process as described by the proposed "Current Good Manufacturing Practice - Guidance for Human Drug Compounding Outsourcing Facilities Under Section 503B of the Federal Food, Drug and Cosmetic Act Guidance for Industry." This article is the first in a series describing vial crimping and capping equipment selection and the qualification necessary to create a well-closed sealed vial in a Current Good Manufacturing Practice environment to ensure patient safety and maintain compliance.Until 1991, Latvia had been part of the Union of Soviet Socialist Republics, and medicines in Latvia were prepared in accordance with the Union of Soviet Socialist Republics Pharmacopoeia and standardized prescriptions. Latvia regained its independence 30 years ago, but Latvia still does not have its standardized prescriptions and official sources of information in the official language. So far, there have been no studies which would collect data about prescribed extemporaneous prescriptions and characterize the current situation in different Latvian regions. For this reason, we analyzed the extemporaneous prescriptions prepared in Latvian pharmacies in 2017. Previous studies identified specialties of those physicians who prescribed extemporaneous prescriptions most often, the most popular dosage forms, as well as identified the active substances, combinations of active substances, and excipients most commonly used in dermatology and rhinology. Having analyzed the compositions prescribed in dermatology and rhinology, our greatest concern was related to the fact that several substances were identified, the use of which in Germany was controversial or even unacceptable in certain dosage forms.
