Differentiated subtypes of nonadherence according to intentionality seem to exist in patients with schizophrenia and schizoaffective disorder. Our findings suggest the need for differentiated approach, both in future research and in clinical practice.

Despite the frequent progression from Parkinson’s disease (PD) to Parkinson’s disease dementia (PDD), the basis to diagnose early-onset Parkinson dementia (EOPD) in the early stage is still insufficient.

To explore the prediction accuracy of sociodemographic factors, Parkinson’s motor symptoms, Parkinson’s non-motor symptoms, and rapid eye movement sleep disorder for diagnosing EOPD using PD multicenter registry data.

This study analyzed 342 Parkinson patients (66 EOPD patients and 276 PD patients with normal cognition), younger than 65 years. An EOPD prediction model was developed using a random forest algorithm and the accuracy of the developed model was compared with the naive Bayesian model and discriminant analysis.

The overall accuracy of the random forest was 89.5%, and was higher than that of discriminant analysis (78.3%) and that of the naive Bayesian model (85.8%). In the random forest model, the Korean Mini Mental State Examination (K-MMSE) score, Korean Montreal Cognitive Assessment (K-MoCA), sum of boxes in Clinical Dementia Rating (CDR), global score of CDR, motor score of Untitled Parkinson’s Disease Rating (UPDRS), and Korean Instrumental Activities of Daily Living (K-IADL) score were confirmed as the major variables with high weight for EOPD prediction. Among them, the K-MMSE score was the most important factor in the final model.

It was found that Parkinson-related motor symptoms (

, motor score of UPDRS) and instrumental daily performance (

, K-IADL score) in addition to cognitive screening indicators (

, K-MMSE score and K-MoCA score) were predictors with high accuracy in EOPD prediction.

Short stems are usually uncemented prosthetics and are recommended in the treatment of traumatic or degenerative diseases of hip. In revision procedures for elderly patients with serious comorbidity, applying a short stem could reduce peri- and post-operative secondary surgical risks to femoral osteotomy, which are necessary for the removal of parts of the implant or acrylic cement from the medullary canal. There are no cases in the literature that apply a short stem for prosthetic revision by acrylic cement anchorage.

A male patient had a left hip replacement in 1995 due to coxarthrosis. At the age of eighty the patient reported an accidental trauma and walked with pain in the left thigh. The X-ray highlighted the stem breakage in the distal section without fracturing the femoral cortex. The patient had various comorbidities (diabetes, anaemia, heart deficiency, and arrhythmia) presenting a high operation risk (ASA 4). During the revision procedure, the distal apex of the stem could not be removed from the femoral cortex. Because of the poor general health of the patient, the surgeon decided not to perform a Wagner femoral osteotomy to remove the distal section of the stem and decided to implant a short stem to avoid removing the stem section of the previous implant. The patient had his left femur X-rayed 15 d post-trauma.

A field of application of short stem may be the development of a cemented short stem to reduce the complexity of the revision procedure.

The correction surgery for severely multidimensional spinal deformity in neurofibromatosis type I is very difficult and it is still a very big challenge for spine surgeons.

A 44-year-old woman presented with progressive kyphosis for more than 10 years and low back pain for 2 years. Quizartinib purchase She had been diagnosed with neurofibromatosis at a local hospital many years ago. Conservative treatments had been applied, but the symptoms got worse rather than alleviated. Therefore, surgery was required.

For this patient with severe deformity, the correction treatment of Ponte osteotomy followed by satellite rod technique in the region of the apical vertebra and the technique of pedicle screws and dual iliac screws had been applied, and successful clinical outcomes were achieved.

The brisement manipulation is an effective treatment for refractory shoulder stiffness. Rotator cuff tears can sometimes exist in combination with adhesive capsulitis. Arthroscopic capsular release combined with rotator cuff repair has achieved good outcomes in published reports.

We report the case of a patient with right shoulder pain for more than 1 year that was suspected to have adhesive capsulitis and a rotator cuff tear that was treated with brisement manipulation and arthroscopic management. An iatrogenic glenoid fracture with shoulder instability occurred during the manipulation. Arthroscopic treatment for fracture fixation, capsular release, and rotator cuff repair was performed, and the functional results are reported.

Arthroscopic fixation for iatrogenic glenoid fracture and repairing coexisting rotator cuff tear can provide the stability needed for early rehabilitation.

Müller-Weiss disease (MWD) is an idiopathic foot condition characterized by spontaneous tarsal “scaphoiditis” in adults. Frequently bilateral and affecting females during the 4

-6

decades of life, the pathogenesis of MWD remains unclear It has been traditionally considered a spontaneous osteonecrosis of the navicular. The typical presentation of MWD is a long period of subtle discomfort followed by prolonged standing, atraumatic, disabling pain. Currently, there is no gold standard for the treatment of patients with MWD. Most support initial conservative therapy. Operative treatment should be considered for failure of conservative therapies longer than 6 months. The indication for surgery is severity of symptoms rather than severity of deformities. Operative treatment options include core decompression, internal fixation of the tarsal navicular, open or arthroscopic triple fusion, talo-navicular or talo-navicular-cuneiform arthrodesis, and navicular excision with reconstruction of the medial column.

In this study, we report four patients affected by MWD.
