Eruptive pseudoangiomatosis is a rare viral exanthem characterized by acute onset of hemangiomata-like lesions, however, histological findings are distinct from that of true angiomas. This entity has been reported from Europe, North America, Japan, and Korea till date. Here, we report 12 cases of eruptive pseudoangiomatosis from a tertiary care hospital in Punjab.

Impaired connectivity is proposed to underlie pathophysiology of schizophrenia. Existing studies on functional connectivity show inconsistent results. We examined functional connectivity in a clinically homogenous sample of 34 early course schizophrenia patients compared with/to 19 healthy controls using resting state functional magnetic resonance imaging (rsfMRI). Mean duration of illness for schizophrenia patients was 4 ± 1.78 years. Following a comprehensive clinical assessment, rsfMRI data were acquired using a 3.0 T magnetic resonance imaging scanner, and analyzed using FSL version 5.01 software (FMRIB's Software Library, www.fmrib.ox.ac.uk/fsl). Compared to healthy controls, schizophrenia patients had significantly decreased functional connectivity in the left fronto-parietal network, lateral and medial visual network, motor network, default mode network and auditory network. Our data suggests significant functional hypoconnectivity in selected brain networks in early schizophrenia patients compared to controls. It is likely that the observed functional hypoconnectivity may be associated with features of schizophrenia other than those examined in this study. It is possible that hypoconnectivity is necessary but not sufficient to the clinical manifestation of schizophrenia. The examination of functional connectivity as a biomarker should be extended to a wider array of disease phenotypes to better understand its significance.

Cutaneous tuberculosis (CTB) is an uncommon small subset of extrapulmonary tuberculosis, comprising 1–1.5% of all extrapulmonary tuberculosis manifestations, which manifests only in 8.4–13.7% of all tuberculosis cases. Lupus vulgaris (LV) and tuberculosis verrucosa cutis (TBVC) are forms of reinfection tuberculosis and often occur in presensitized patients, by exogenous inoculation. We report two cases of cutaneous tuberculosis at unusual sites. A 35-year-old female having a forehead lesion for 2 years was diagnosed as having tuberculosis verrucosa cutis and another 16-year-old girl with lesion in left axilla for 10 years was proven to have lupus vulgaris. The delayed diagnosis was possibly due to lower clinical suspicion due to the presentation of CTB at unusual sites. This highlights the importance of keeping TB as an important differential as misdiagnosis or delayed diagnosis of this entity can lead to prolonged morbidity.
