The fibrosis involved in gluteus maximus causing limitation of flexion and adduction of the hip has become a recognized clinical entity since the first report by Fernandez de Valderrma in 1969. Its most constant and characteristic histologic feature was substitution of the fibrous tissue in the definitive etiology was unknown but presumed to be multiple intramuscular injections. Authors present three cases of the fibrosis involving gluteus maximus. In two cases Z-lengthening was performed on the thickened fibrous bands with good results.

Dislocation of the shoulder after intramuscular injection antibiotic(s) is rare and this conditon was limit described in literature. Our purposes were: (1) determining the clinical symptoms, X-ray and CT findings; and (2) determining the indications and the surgical technique and evaluation of the surgical result. Material and methods: 62 children (29 females, 33 males) aged from 4 to 16 years were included. Clinical and X- ray findings were analysed for anterosuperior subluxation or dislocation of humeral head. The patients were operated to release of origin or insretion of the mild Deltoid muscle or Z plasty of this one. Surgical procedures provided good result in 75.3 percent, fair in 24.7 percent and there were no infection or neuromuscular complication in these cases. Conclusions: This condition always resulted from repeated Deltoid intramuscular injection. The surgical treatment with resection of fibrous portions constantly gives relief of symptoms and provides good function.

Esfenvalerate is a kind of commonly used highly effective pyrethroid insecticide. It is common for people who are poisoned by contact or misuse, but rarely reported for people who are poisoned by intramuscular injection. This paper reports a case of intramuscular injection of esfenvalerate in the Department of Infection, West China Hospital of Sichuan University in November 2021. The patient was intramuscularly injected with about 20 ml of esfenvalerate, inducing the sense of swelling and tingling, degeneration and necrosis of striated muscle tissue at the injection site, also liver function damage and other manifestations. The patient was discharged from hospital after rehydration, accelerating poison metabolism, anti-infection, liver protection and local puncture.

Nicolau syndrome is a rare adverse reaction of the skin at the site of intramuscular drug injection, and has largely unidentified pathogenesis. It consists of the development of an acute, severe pain and a localized erythematous rash during intramuscular injection leading to cutaneous, subcutaneous and even muscular necrosis. We report a case of a 55-year-old woman who presented with a painful skin necrosis in her buttocks following an intramuscular diclofenac-beta-dimethyl-aminoethanol injection.

PURPOSE: We evaluated the effectiveness of tamsulosin on the expectant treatment for the patients suffering with lower ureteral stones. MATERIALS AND METHODS: A total of 67 patients with stones less than 5mm that were located in the lower ureter were enrolled in the study. The patients were randomly divided into two groups. Group 1 (n=32) received 20mg caroverine (a spasmolytic drug) orally three time a day. Group 2 (n=35) received 0.2mg tamsulosin orally one time a day. The treatment was continued until expulsion of stone or to a maximum of 28 days. All patients were allowed 30mg ketorolac trimethamine intramuscular injections on demand. We compared the two groups for stone size, the expulsion rate, the time to expulsion and use of analgesics. RESULTS: The average stone size was 4.3+/-0.61mm for group 1 and 4.4+/-0.51mm for group 2. No statistical difference between two groups was found for stone size, age and sexual distribution. The expulsion rate was significantly higher in group 2 (82.8%), compared with group 1 (53.1%) (p=0.002). The mean expulsion time was 8.3 days for group 1 and 4.6 days for group 2 (p<0.0001). The average number of intramuscular analgesic injections was 3.9 for group 1 and 1.1 for group 2 (p<0.0001). CONCLUSIONS: Tamsulosin was proved to be effective and safe, as demonstrated by the increased stone expulsion rate, the decreased expulsion time and the reduced use of pain control in the expectant treatment of the lower ureter stones.

Traumatic scars on skin covering areas of high movement, especially areas on the face, can be stressful for patients. We report two cases of traumatic scars that occurred on the chin, and that were successfully treated with a combined therapy of 595-nm pulsed dye laser (PDL) and intramuscular injection of botulinum toxin. After the treatment, good cosmetic results were achieved in both patients. The only adverse effect during and after the treatments was mild pain, which resolved within several days without any additional treatment. In conclusion, the combination of 595-nm PDL and intramuscular botulinum toxin injection was shown to be a safe and effective treatment for traumatic scars on the mobile chin area in Korean patients.

Although anaphylactic shock during the perioperative period is rare, it can be lethal due to severe cardiovascular and respiratory collapse. Midazolam is generally used as premedication for relieving anxiety about the operation, and the danger of anaphylactic shock after intramuscular injection is not widely recognized. We report the first case of anaphylactic shock occurring during the perioperative period after intramuscular injection of midazolam. Since anaphylactic shock after intramuscular injection can be of slow onset, the operation should be delayed if an anaphylactic reaction is suspected, even if the symptoms are limited. In addition, anesthesiologists should be prepared for the occurrence of anaphylaxis at any time in the perioperative period.

PURPOSE: The evaluation of pain in neonates is difficult due to their limited means of communication. The aim of this study was to determine whether the behavioral reactions of facial action and cry provoked by an invasive pain-induced procedure could be discriminated from the reactions to a noninvasive pain-induced procedure in normal full-term neonates. METHODS: Thirty-six healthy full-term neonates received three pain-induced procedures in counterbalanced order:intramuscular injection, tactile stimulus, and rubbing thigh with alcohol. The facial actions to the pain-induced procedures were measured and analysed by Neonatal Facial Action Coding System (NFACS) and the cry measures were analysed by the speech analysis after recording. RESULTS: 1) A cluster of facial actions comprised of brow bulging, eye squeezing, deepening of nasolabial furrow and open mouth was associated most frequently with the invasive procedure and the total facial action was the highest score in intramuscular injection. 2) Acoustic analysis of cry showed the shortest latency to the first cry and the lonegst duration of the first cry in intramuscular injection. 3) Two variables, total facial action and duration of the first cry, were most statistically significant in discriminating the invasive pain-induced procedure from the noninvasve pain-induced procedure. CONCLUSION: The facial actions and cry responses to the invasive pain-induced procedure were significantly different from the responses to the noninvasive pain-induced procedure in healthy full-term neonates.
