The aim of this study was to determine the impact of two different IM methylprednisolone injection speeds on pain intensity and pain duration. A one-group quasiexperimental design was used to study 10second versus 30-second injection durations. According to the formula for one sample using average values, 25 patients were recruited from a dermatology clinic. Data were collected using the ''Patient Characteristics Form'' and the visual analog scale (VAS). The mean difference in pain levels according to the VAS in the postinjection period was significantly higher with administration of IM methylprednisolone in 10 seconds compared with 30-second administration (VAS 1.9 vs. 1.3; p < .05). The severity of pain peaked at 0 minutes for both injection speeds, but the duration of pain was longer with 10-second injections. The data showed that at multiple time points after 10-second injections, men and patients >40 years old experienced greater pain severity. Pain severity after 30-second injections was greater for patients of normal or low weight who had completed higher levels of education. In conclusion, slow IM injection of steroids improves pain management.

This study aimed to examine the health problems encountered during diving and to ascertain the factors associated with adverse events. Methods. The sample of this descriptive study consisted of 132 recreational divers from diving schools in Ankara. The researchers collected the data using a questionnaire developed according to the relevant literature. Results. Diving-related health issues including barotraumas, nitrogen narcosis, and decompression sickness were mostly dependent on depth. The divers with higher certification levels witnessed diving-related adverse events more frequently and a significant increase in health problems with greater depth attained (p < 0.05). More experienced divers with longer duration of diving (p < 0.05) and greater number of dives reported more health problems associated with diving between 41 and 65 m. Adverse events did not differ according to diving-related educational features (p > 0.05). Conclusions. The finding implies the importance of adherence to the depth limit of 40 m for recreational divers, being a slow ascend diver, and utilization of a buddy system in order to prevent diving-related adverse events. A data recording system related to diving and regulations particularly for tourist divers in the countries attracting tourists is required.
