Intestinal pseudo-obstruction (IPO) is a rare and poorly understood manifestation of systemic lupus erythematosus (SLE), especially in children. The characteristic clinical feature of IPO is obstruction without an identifiable obstructive lesion. The authors a 13-year-old girl whose first symptom of SLE was IPO. The patient presented with a 3-day history of nausea, bilious vomiting, abdominal distention, and no bowel movement. Simple abdominal radiographs revealed mild dilatation with partial air-fluid levels in the small intestine. Abdominal CT and methylcellulose small bowel studies showed massive ascites, engorgement of the small mesenteric vessels, pleural effusion, and diffuse bowel wall thickening of the gastric antrum, duodenum. and jejunum. The delayed passage of contrast for 15 days after the methylcellulose small bowel studies was suggestive of decreased bowel motility. Laboratory findings were positive for ANA, anti-double-stranded DNA, anti-Smith and lymphopenia. After 10-day treatment with high-dose corticosteroids, the symptoms improved. IPO associated with SLE should be considered in the differential diagnosis for patients presenting with symptoms of intestinal obstruction. Early recognition of IPO in SLE and appropriate therapy are important for prevention of complications and unnecessary surgery. This case raises awareness among pediatricians that although rare, IPO can be the presenting symptom of SLE in children.

Background: This study aimed to evaluate the co-administration effect of atelocollagen combined with hyaluronic acid (HA) injections fortreatment of full-thickness rotator cuff tear (RCT). Methods: Eighty patients who underwent arthroscopic rotator cuff repair for full-thickness RCT from March 2018 to November 2019 wereenrolled. The patients were randomly allocated to the following groups: combined atelocollagen and HA injection (group I, n=28), only HAinjection (group II, n=26), and no injection (group III, n=26). Clinical outcomes were assessed at 3, 6, and 12 months after surgery usingthe American Shoulder and Elbow Surgeons score, visual analog scale pain score, functional scores (pain visual analog scale, function visualanalog score), and range of motion. Magnetic resonance imaging was performed 12 months after surgery to evaluate rotator cuff integrity. Results: Preoperative demographic data and postoperative clinical outcomes did not differ significantly among the three groups (p>0.05).However, in group I, the number of steroid injections after surgery was significantly lower than that in the other groups (p=0.011). The retear rate on follow-up magnetic resonance imaging was significantly higher in group II (9.5%, n=2) and group III (13.6%, n=3) than ingroup I (0%, p=0.021). Conclusions Co-administration of atelocollagen and HA improves healing of the rotator cuff and increases the integrity of the rotator cuffrepair site. This study provides encouraging evidence for use of combined atelocollagen-HA injections to treat patients with full-thicknessRCT.
