Are Junior Residents Competent at Closed Reduction and Casting of Distal Radius Fractures in Children?

BACKGROUND

At many institutions, junior orthopaedic surgery residents perform the closed reduction and casting of pediatric distal radius fractures (DRFs). The purpose of this study was to evaluate the competency of junior residents compared to senior residents in the initial management of pediatric DRFs.

METHODS

This investigation was a case-control study analyzing the outcomes of children with displaced DRFs treated by junior versus senior residents. The cohorts were matched with respect to fracture type. Radiographs were measured to assess fracture angulation, displacement, and cast index. Comparisons of patient characteristics, fracture characteristics, and outcome variables were made between the cohorts.

RESULTS

A total of 132 patients (99 males; mean age 10.7±2.6 years) were included. Junior residents achieved a similar rate of acceptable initial reduction compared to senior residents (82% versus 79%; p=0.66). Twenty-four (23%) patients were found to have loss of reduction (LOR), though the rate of LOR was similar in the junior (16.7%) and senior resident (28.9%) cohorts (p=0.13). Overall, only 6 patients (3.7%) required surgery (1.5% in junior versus 7.6% in senior; p=0.09). The odds of LOR were 2.7 times higher in the first three reductions of the rotation for all residents (p=0.049).

CONCLUSION

Junior residents perform similarly to senior residents in the closed reduction and casting of pediatric DRFs. However, residents performing one of their first three closed reductions during a rotation-regardless of seniority-were more likely to experience subsequent loss of reduction, suggesting the need for close supervision during the beginning of each rotation.Level of Evidence: III.

Dysplasia-associated lesion or mass (DALM) detected by colonoscopy in long-standing ulcerative colitis: an indication for colectomy

In performing colonoscopy over a 4-yr period on 112 patients with long-standing ulcerative colitis, a dysplasia-associated lesion or mass (DALM) was found in 12. This appeared as either a single polypoid mass (5 cases), a plaquelike lesion (2 cases), or multiple polyps (5 cases). In 7 of these 12 cases carcinoma was subsequently found. This was particularly true in the 5 cases of single polypoid masses where all 5 contained invasive carcinoma. In none of the cases associated with malignancy did multiple biopsies of the DALM reveal invasive carcinoma. In only 2 of the 7 patients with carcinoma was the dysplasia "severe," being "mild" or "moderate" in the remaining 5. In the 27 patients with dysplasia found incidentally in random biopsies of flat mucosa only one carcinoma was found, in contrast to the 7 cancers in 12 patients with DALM. This difference leads us to regard the finding of DALM, especially a single polypoid mass, as highly significant in patients with long-standing ulcerative colitis. It carries a sufficiently high risk of cancer, thereby constituting a strong indication for colectomy.

Endoscopic diagnosis and therapy of mucosal vascular abnormalities of the gastrointestinal tract occurring in elderly patients and associated with cardiac, vascular, and pulmonary disease

Twenty-seven cases of mucosal vascular abnormalities of the gastrointestinal tract were demonstrated by endoscopy, usually during investigation for gastrointestinal bleeding. The lesions were flat, bright red, and seen clearly through the endoscope. All were successfully treated by endoscopic electrocoagulation without complication. The vascular abnormalities were situated in the colons of 24 patients and in the stomachs of 3 patients. The average age of the patients was 69 years. Twenty-two of the 27 patients had some type of associated cardiac, vascular, or pulmonary disease that apparently represents a syndrome. The author proposes a theory that the vascular lesions are acquired as a consequence of hypo-oxygenation of the colon mucosa.

Opportunistic pneumonia: a clinicopathological study of five cases caused by an unidentified acid-fast bacterium

Five patients had opportunistic pulmonary infection caused by acid-fast bacilli, unusual clinical presentations and a unique pathological picture. Clinically, these cases mimicked septic pulmonary emboli or bacterial pneumonia. The infection was temporally related to high-dose corticosteroid therapy, given for renal-transplant rejection in four patients and for therapy of lymphocytic lymphoma in one. Histologic sections of lung-biopsy or autopsy material showed an acute suppurative pneumonia with dense alveolar infiltration by neutrophils, without granuloma formation or caseous necrosis. Predominantly intracellular acid-fast bacilli were present. The organism failed to grow in culture on routine bacterial, fungal and mycobacterial mediums. This unusual and possibly new acid-fast organism is a probable cause of suppurative pneumonia in impaired hosts receiving corticosteroid therapy.
