Obstruction due to persimmon bezoars: computed tomography detection.

BACKGROUND/AIMS: Small-bowel obstructions caused by persimmon bezoars are uncommon, and the diagnosis is difficult before operation. The aim of this study was to present computed tomography findings of persimmon bezoars in the small bowel. METHODOLOGY: We reviewed 3 cases diagnosed with small-bowel obstruction caused by persimmon bezoars between April 1997 and March 1999 at Chikamori Hospital. RESULTS: The cause of the small-bowel obstruction was bezoars in the 3 patients. Abdominal computed tomography performed before operation revealed a well-defined, intraluminal inhomogeneous mottled mass containing gas bubbles. CONCLUSIONS: Computed tomography is useful for diagnosing obstructed small-bowel persimmon bezoars.

Magnetic resonance imaging findings and treatment outcome in late-onset tibia vara.

Several retrospective studies have shown the usefulness of magnetic resonance imaging (MRI) in the evaluation of tibia vara. With respect to the late-onset type, however, there have been no English-language reports on MRI findings. In this article, the authors report on the MRI features of three patients with late-onset tibia vara, the results of treatment that was chosen on the basis of the findings, and the histologic characteristics of the disease. Fat-suppressed MRI revealed partial closure of the tibial physis in one patient and near-closure in another patient. They underwent osteotomy with resection of the bone bridge and have shown no evidence of recurrence. In the third patient, only irregularity of the physis was found on MRI, and she was treated conservatively. Her varus deformity subsequently improved, although it persisted. Histologic examination revealed disorganization and misalignment of the physeal zone and transverse alignment of the trabeculae. The patient with a bony bridge also had discrete ossification centers in the physeal zone.

Congenital dislocation of the knee reduced spontaneously or with minimal treatment.

Six cases of congenital dislocation of the knee (CDK) reduced spontaneously or with minimal treatment were investigated. Reduction was achieved from 4 days to 3 months after birth. Clinical results were good, although in four cases, hyperextension < or = 20 degrees persisted. In view of the perinatal complications and associated anomalies, CDK reduced with no or minimal treatment is supposed to be a category of congenital postural deformity. We believe that it is advisable to wait 1 month for spontaneous reduction of CDK in cases not associated with clubfoot, arthrogryposis multiplex congenita, and Larsen's syndrome.

Stature and severity in multiple epiphyseal dysplasia.

We investigated the stature and radiological findings in 15 patients with multiple epiphyseal dysplasia (MED). They were divided into normal-stature and short-stature groups according to their body height after 4 or 5 years of age. Their stature was not related to the involvement of the spine or epiphyses of long tubular bones except for the distal radius. Proximal phalanges and metacarpi were shorter in the short-stature group than in the normal-stature group, indicating that stature in MED had some relationship to the involvement of the wrist and hand. However, some patients in the normal-stature group showed involvement of distal radial epiphyses, and some patients in the short-stature group did not have stubby fingers. There are thus no clear-cut criteria to differentiate between the severe Fairbank type and the milder Ribbing type of MED.
