Because tuberculosis of the skull is relatively unusual occurrence, it may not be immediately recognized. It responds readily to chemotherapy and should be suspected in disseminated tuberculosis or in any draining lesion of the skull that is sterile or fails to respond to conventional antibiotic therapy.

Haematologica vol. 85(8):August 2000 treatment and at the same time for OAT is not an unusual occurrence considering the association between cancer and some immunologic diseases with thromboembolic complications. In order to treat such patients properly, it is therefore important to be aware of these pharmacologic interactions that seem to differ with respect to the oral anticoagulant prescribed.

Emotional facial palsy (EFP) commonly results from anterolateral thalamic or striatocapsular infarcts. Its occurrence in brainstem lesions is uncommon, with previously reported cases being restricted to superior cerebellar artery infarction (3 cases). We report an unusual case of EFP ipsilateral to an anterior inferior cerebellar artery infarction, which opens new insights into the facial corti...

The leaves of Eupatorium semialatum were investigated for the occurrence of pyrrolizidine alkaloids. Although this type of alkaloids generally occurs in the Eupatorieae, only unusual non-toxic pyrrolizidines of the tussilagin type were identified. All compounds are methyl esters of the corresponding beta-amino acids.

OBJECTIVE Partial demarcation and infarction of the upper pole of the spleen is not a rare occurrence after laparoscopic sleeve gastrectomy (LSG). However, development of an abscess in the absence of leakage is extremely rare. CASE REPORTS We present herein two unusual case reports of splenic abscess in patients following LSG.

We have considered chiral-achiral phase transitions that can occur in some liquid crystals. This study deals with such transformations induced by external electric and magnetic fields. We discuss phase changes mediated by disclinations, single solitons, soliton lattices and those occurring without any defect. Some unusual aspects ofthese transitions such as reentrance, occurrence of tricritical...

A case is reported of a 30 year old man with a testicular seminoma. He had presented 16 years previously with a pineal germinoma, followed two years later by intracranial metastases. This is an unusual occurrence of double pathology in the germ cell line.

The metastases to the TMJ from a primary lung tumour is a very rare occurrence. This case is unusual in several aspects, as the non-reducible dislocation of the TMJ was the first clinical manifestation of the tumour. CT staging showed that this secondary tumour in the condyle was the only bone metastasis.

A case of alopecia areata followed by relapsing polychondritis is presented. Similar cases from the literature are reviewed and speculation about the relationship of these diseases is offered. Although the occurrence of these diseases together could be coincidental, an association seems immunologically plausible. Thus, relapsing polychondritis might be an unusual systemic manifestation of alope...

A patient with bilateral, simultaneous ureteral tumors is described. A brief comment on therapeutic techniques utilized in previous cases is presented. Ureteral tumors are not a common occurrence in clinical practice. Simultaneous bilateral ureteral tumors are very unusual and raise interesting therapeutic dilemmas. We describe a patient with simultaneous, bilateral ureteral tumors.
