Camptocormia is defined as a forced posture with a forward-bent trunk which appears during standing and sitting. It was first described in 1818 by Brodie. In the last 100 years, numerous cases were observed. A psychogenic origin was presumed in most cases. We describe four patients with typical symptoms of camptocormia who present with the clinical and electromyographical criteria of a segmental dystonia. A new classification of camptocormia is proposed including (1) the primary form, a segmental dystonia of the abdominal wall muscles and (2) secondary forms. Among other conditions (psychogenic disorder, neurosis, myopathy, myositis, Parkinson's disease, multiple-system atrophy, thoracolumbar kyphosis, paraneoplastic syndrome), camptocormia is to be considered in essential tremor. A combination of dystonia of the abdominal wall muscles and essential tremor seems possible.

To improve the diagnostic accuracy of sporadic spinocerebellar degeneration (SCD), we assessed the clinical and pathological data of 1494 consecutive autopsy cases. The number of patients who received a diagnosis of sporadic SCD (including multiple system atrophy) either clinically or pathologically was 19 (1.3%). We identified six cases with clinical misdiagnoses of SCD that were confirmed pathologically as progressive supranuclear palsy (PSP, four cases), basilar artery thrombosis (one case) and unclassified tauopathy (one case). The total number of patients who received a clinical diagnosis of sporadic SCD was 93 and the positive predictive value was 93.5%. We also identified 13 autopsy cases that were pathologically confirmed as SCD, but had been clinically misdiagnosed as having other disorders. Their clinical diagnoses comprised progressive supranuclear palsy (five cases) and Parkinson's disease (PD, four cases), as well as parkinsonism with dementia, amyotrophic lateral sclerosis, paraneoplastic syndrome and multiple cerebral infarction (one case each). The results indicate that it is often difficult to distinguish PSP and PD from SCD, because of the atypical combination of symptoms or atypical timing of the appearance of symptoms, such as severe autonomic failure, cognitive impairment, poor L-dopa responsiveness, early cerebellar signs and obvious vertical gaze palsy.

Tumour-induced osteomalacia (TIO), or oncogenic osteomalacia, is a paraneoplastic syndrome marked by hypophosphataemia, renal phosphate wasting, bone pain, weakness, and fractures. The syndrome has been reported with both benign and malignant tumours including parotid gland basal cell tumours, thyroid carcinomas, colon adenocarcinomas, and prostate cancer. Often, the syndrome is marked by an insidious course during which patients present with generalised bony pain and weakness, which do not resolve until the underlying tumour is identified and treated. We present a case of a patient with Parkinson's disease whose subacute weakness, lower extremity paresis, and renal phosphate wasting led to the synchronous diagnosis of metastatic prostate adenocarcinoma and TIO.
