The availability of human genome sequence has transformed biomedical research over the past decade. However, an equivalent map for the human proteome with direct measurements of proteins and peptides does not exist yet. Here, we present a draft map of the human proteome using high resolution Fourier transform mass spectrometry. In-depth proteomic profiling of 30 histologically normal human samples including 17 adult tissues, 7 fetal tissues and 6 purified primary hematopoietic cells resulted in identification of proteins encoded by 17,294 genes accounting for ~84% of the total annotated protein-coding genes in humans. A unique and comprehensive strategy for proteogenomic analysis enabled us to discover a number of novel protein-coding regions, which includes translated pseudogenes, non-coding RNAs and upstream ORFs. This large human proteome catalog (available as an interactive web-based resource at http://www.humanproteomemap.org) will complement available human genome and transcriptome data to accelerate biomedical research in health and disease.

Object Patient age at presentation with congenital atlantoaxial dislocation (CAAD) is variable. In addition, the factors determining irreducibility or reducibility in these patients remain unclear. The facets appear to contribute to the stability of the joint, albeit to an unknown extent. The objective of this paper was to study the characteristics of C1–2 facets in these patients and their bearing on the clinicoradiological presentation and management. Methods Twenty-four patients with CAAD were studied. Fifteen patients had irreducible CAAD (IrAAD); 3 of these patients experienced incomplete reduction after traction, and 9 had reducible CAAD (RAAD). The images (CT scans of the craniovertebral junction in a neutral position) obtained in the parasagittal, axial, and coronal planes were studied with respect to the C1–2 facets and were compared with 32 control scans. The inferior sagittal and coronal C-1 facet angles were measured. The lordosis of the cervical spine (cervical spine angle calculated on radiographs of the cervical spine, neutral view) in these patients was compared with normal. The management of these patients is described. Results The inferior sagittal C-1 facet angle and at least one coronal angle in patients with IrAAD were significantly acute compared with those in patients with RAAD and the control population. A significant correlation was found between age and the acuteness of the inferior sagittal C-1 facet angle (that is, the more acute the angle, the earlier the presentation). The lordosis of the cervical spine was exaggerated in patients with IrAAD. Three patients with IrAAD who had smaller acute angles experienced a partial reduction after traction and a complete reduction after intraoperative distraction of the facets, thereby avoiding a transoral procedure. An inferior sagittal C-1 facet angle of more than 150° in the sagittal plane predicted reducibility. Drilling a wedge off the facet in the sagittal plane to make the inferior sagittal C-1 facet angle 150° can reduce the C1–2 joint intraoperatively by posterior approach alone. Conclusions The acuteness of the inferior C-1 sagittal facet angles possibly determines the age at presentation and reducibility. The coronal angles determine the telescoping of C-2 within C-1. Patients with IrAAD can be treated using a posterior approach alone with the exception of those with extremely acute angles or a retroflexed dens. The exaggerated lordosis of the cervical spine in these patients is a compensatory phenomenon.

Brain abscess caused by Cladophialophora bantiana is a rare disease associated with high mortality due to delay in diagnosis and absence of standardized therapy. We reviewed 124 culture proven C. bantiana brain abscess cases; 103 cases published in English literature during 1952 through 2014 and 21 unpublished cases from our reference center. The majority (57.3%) of the patients was from Asian countries especially from India (62/124, 50%). The diagnosis of the cases was delayed with mean duration 115 days after developing symptoms. The disease was nearly equally distributed in immunocompetent and immunosuppressed hosts but associated with significantly higher mortality (77.1%) in later group. Complete excision of brain lesion in immunocompetent host led to significantly better survival (43.7%). Though all commercially available antifungal drugs have been used in these patients, amphotericin B deoxycholate or lipid preparations were most commonly (62.83%) prescribed agent. None of the drugs used was found to be independently associated with improved outcome. In vitro antifungal susceptibility testing of 13 isolates of our center, demonstrated good activity to voriconazole, posaconazole, and itraconazole, but these triazoles were prescribed in only 29.2% patients. Increased awareness with early suspicion of the disease, and aggressive medical and surgical approach in treating these patients may improve the outcome.

The mainstay of management of tuberculosis of the craniovertebral junction is prolonged antitubercular treatment with a rigid external immobilization. Surgery is not necessary, even in patients with advanced stages of disease. Complete clinical and radiological healing occurs in all patients with conservative treatment.

Development of a contralateral epidural haematoma during or immediately after cranial surgery is a well-described entity. However, in a case of acute subdural haematoma where the brain is usually tense, postoperative development of contralateral extradural haematoma is uncommon. We report two cases of contralateral extradural haematoma after decompressive surgery for acute subdural haematoma. We recommend routine postoperative CT immediately after cranial surgery for head trauma. This would help in timely detection and treatment of such a complication.
