ABSTRACT
The incidence of cavum septum pellucidum (CSP), which has been widely regarded as a developmental anomaly of little clinical importance in neuropathology, was examined in 113 patients with affective disorders (69 with bipolar disorder and 44 with major depression), 40 schizophrenic patients, and 92 control subjects by magnetic resonance imaging (MRI). Significantly higher incidence of Grade 3-4 CSP (moderate to large) compared with the controls was found only in the schizophrenics. When a broader interpretation of CSP, including indeterminant (Grade 1) and small (Grade 2) CSP was used, three additional patients with bipolar disorder were found to have Grade 1-2 CSP, and the total prevalence of Grade 1-4 CSP in the patients with bipolar disorder was significantly higher than that in the control subjects but slightly lower than that in the schizophrenic patients. CSP was not observed in any patient with major depression. There were no differences between the patients with and without CSP in age, sex, education, or the duration of illness. These findings are consistent with the hypothesis that neurodevelopmental abnormality may be present in schizophrenia, and such an abnormality may also be present in some patients with bipolar disorder.

We report a 73-year-old woman with typical clinical, histological and immunofluorescence features of pemphigoid nodularis. Direct immunofluorescence studies of prurigo nodularis-like lesions and peribullous skin showed the linear deposition of IgG and C3 at the basement membrane zone. Circulating IgG against the basement membrane was also detected by indirect immunofluorescence. The serum from the patient was shown to contain the autoantibody against 230 kDa hemidesmosomal antigen associated with bullous pemphigoid antigen.
