Adenocarcinoma or early-stage cervical cancer is a risk factor for preterm delivery after cervical conization: a multicenter observational study.

Objective: Pregnancy after conization is associated with a high risk of preterm delivery. However, because risk factors for preterm delivery after conization remain unknown, we conducted a multicenter observational study to investigate risk factors associated with preterm delivery.

Methods: We selected patients who had previously undergone conization and reviewed medical records from 18 hospitals in cooperation with Keio University School of Medicine between January 2013 and December 2019.

Current Status of the Obstetric Compensation System for Cases of Cerebral Palsy at a General Hospital in Tochigi, Japan.

. The Japan Obstetric Compensation System for Cerebral Palsy (JOCSC) was launched in January 2009 as the first nationwide nofault compensation system. The aim of the study was to clarify the present status of functioning of the JOCSC in pediatric and obstetric departments at a general hospital.

Surgical treatment of Charcot spine.

The authors report 4 cases of Charcot spine treated surgically. In the surgical treatment, combined anterior and posterior with extensive debridement, autogenous bone grafting, and posterior instrumentation is the main therapeutic modality. Some cases with mild bone destruction could be treated by posterior interbody fusion.

Surgical treatment of lumbar ossification of the posterior longitudinal ligament. Report of two cases and description of surgical technique.

The authors report two cases of patients with lumbar ossification of the posterior longitudinal ligament (OPLL). One patient underwent surgery via the single posterior approach, and the other patient underwent combined anterior-posterior surgery. The authors consider the anterior approach for excision of the ossified lesion to be the most reasonable for treatment of lumbar OPLL.

Cervical laminoplasty for subaxial lesion in rheumatoid arthritis.

Expansive laminoplasty of the cervical spine was performed for 15 patients with subaxial lesion (SAL) in rheumatoid arthritis (RA) with or without symptomatic occipitocervical pathology. Clinical results were satisfactory, and radiographic evaluation revealed that the range of movement of the cervical spine decreased to 56.3%, spinal alignment was well preserved, and intervertebral slipping advanced only slightly.

Gait analysis of patients with neurogenic intermittent claudication.

Study Design: The gait of patients with neurogenic intermittent claudication was analyzed before and after surgery using a ground reaction force plate.

Objectives: To analyze the gait characteristics of patients with neurogenic intermittent claudication, to evaluate quantitatively their gait improvement after surgical treatment, and to examine the differences in gait characteristics and postoperative improvement among different types of neuropathy.

Summary Of Background Data: A number of reports have been published on the pathophysiology or treatment of neurogenic intermittent claudication.

Nodal marginal zone B-cell lymphoma resembling plasmacytoma arising from a plasma cell variant of localized Castleman's disease: a case report.

Nodal marginal zone B-cell lymphoma (NMZBL) occasionally represents prominent plasma cell differentiation. Recently, primary lymph node plasmacytoma has been suggested to represent an extremely plasmacytic differentiation of NMZBL. We here report a case of NMZBL showing histological features resembling plasmacytoma arising from a plasma cell variant of localized Castleman's disease (PCLCD).
