Lipoma is the most common benign soft tissue tumour with most located in the superficial subcutaneous plane. However, some are located in the deeper plane. Location in the head and neck regions are less common compared to the other part of the body. Deep seated lipomas are either inter-muscular or intramuscular. We present a case of a simple subcutaneous neck lipoma in a 60-year-old Malay man which turned out to be an intramuscular sternocleidomastoid lipoma.

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 or embolia cutis medicamentosa is an acute necrotic condition of skin that follows intramuscular injection of drugs. A 36-year-old man developed a painful, purpuric and erythematous patch on his left buttock following an intramuscular injection of diclofenac sodium. Histologically, the patch lesion displayed epidermal necrosis, dermal degeneration, and vascular thrombosis. We report a rare case of Nicolau syndrome following intramuscular injection of diclofenac sodium. In our case, the patient was successfully treated by surgical excision with primary closure.

PURPOSE: We evaluates if the administration of tamsulosin increases the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the patients with upper ureteral stones and if this decreased the use of analgesic drugs after the procedure. MATERIALS AND METHODS: A total of 45 patients with stones 6-12mm in size that were located in the upper ureter were enrolled in the study. The patients were randomly divided into two groups. Group 1 (n=23) received 3 times a day oral treatment of 20mg caroverine (a spasmolytic drug). Group 2 (n=22) received one time a day oral therapy of 0.2mg tamsulosin. All the patients received oral treatment for 14 days. Both groups of patients were allowed to use 30mg ketorolac trimethamine intramuscular injections on demand. The endpoint of the study was the stone expulsion rate, the use of analgesics and the drug adverse effects during treatment. RESULTS: The average stone size was 7.9+/-2.79mm for group 1 and 8.2+/-3.14mm for group 2. No statistical difference between the two groups was found for the stone size, age and gender distribution. The expulsion rate was significantly higher in group 2 (90.9%) compared with group 1 (65.2%) (p=0.038). The average number of pain control injections was 0.78 for group 1 and 0.23 for group 2, and there was a statistically significant difference between the two groups (p=0.042). CONCLUSIONS: The use of tamsulosin proved to be effective and safe, as demonstrated by the increased stone expulsion rate and the lesser need for pain control than that when using just a spasmolytic drug for ESWL of upper ureter stones.

BACKGROUND: The stress of operation inhibits bowel motility. The blockade of efferent sympathetic nerve is helpful to recovery of bowel motility. So we tried to examine that the extent of sympathetic blockade by alterations of bupivacaine infusion rate affected the recovery of bowel motility. METHODS: Group 1 (N = 25) received postoperative meperidine intramuscular injection on demand as a control group, group 2 (N = 25) received postoperative epidural 0.125% bupivacaine 100 ml plus morphine 10mg by infusion pump, 1 ml/hour, for 4days, group 3 (N = 25) received 0.125% bupivacaine 400 ml plus morphine 10mg by infusion pump, 4 ml/hour, for 4days. The Group 2 and 3 received additional morphine 2mg in 0.2% bupivacaine 10 ml epidurally as a single bolus when the peritoneum was closed. The time interval from termination of operation to the first passage of flatus was estimated. RESULTS: In group 1, bowel motility was regained at 92+/-23 hours, group 2 ; 90+/-19 hours and group 3 ; 91+/-19 hours. All values are not significantly different among the groups (p>0.05). CONCLUSIONS: The alteration of epidural bupivacaine and morphine infusion rate did not affect the recovery of postoperative bowel motility.

We induced apoptosis in normal rats by intramuscular injection of 5-fluorouracil (5-FU) and immunohistochemically evaluated the thymus for the TdT-mediated dUTP biotin nick end labelling on the 1st, 3rd, 6th, 9th, 15th and 21st days following the bolus intramuscular injection. The injections of 5-FU induced a greater extent of apoptosis in the thymus. In the thymus, a mild increase in apoptosis was observed 24 hours after injection. The greatest number of apoptotic cells were seen at 72 hours. The size of the thymus decreased and the cortex thinned with hypocellularity. The injection of 5-FU caused massive cell loss in the thymus. Most apoptotic cells were scattered in the cortex and lower levels of apoptosis were also observed in the medulla. After 72 hours, the level of apoptosis returned to the control level. Considering the above results, we think that 5-FU induced toxicity may be related to 5-FU induced apoptosis in normal tissue, especially the thymus.
