ABSTRACT
BACKGROUND: Knowledge of elbow collateral ligament length during passive motion is essential in understanding ligament physiology and pathology, such as tightness and instability. METHODS: Five anatomical unembalmed specimens were passively placed in six flexion positions together with three forearm rotations, using equipment with gravity as motion force. These 18 positions were recorded using CT-scan. Three-dimensional data of ligament insertions were obtained through anatomical millimetre sections. Ligament length was measured in each position. FINDINGS: In neutral rotation, the lateral collateral ligament was long between 0 degrees and 30 degrees as well as at 90 degrees, and short between about 60 degrees and 120 degrees of flexion. In pronation, it was long at about 0 degrees and between 60 degrees and 120 degrees, short at about 30 degrees of flexion. In supination, it was long at about 30 degrees and 90 degrees and short between 120 degrees and 150 degrees of flexion. In any forearm rotation, the highest length of the anterior bundle of the ulnar collateral ligament was measured at about 90 degrees, its smallest length between 120 degrees and 150 degrees of flexion, position at which the posterior bundle length was greatest. INTERPRETATION: At 60 degrees of flexion, the collateral ligaments were slackened in any forearm rotations. Forearm rotation plays an indirect role in the posterolateral stability of elbow as it changes length of the lateral collateral ligament. This ligament can be tested passively at 90 degrees of flexion in supination, the anterior bundle of the ulnar collateral ligament between 0 degrees and 30 degrees in neutral rotation and the posterior bundle between 120 degrees and 150 degrees in neutral rotation.

The essential oils of Hyptis suaveolens plants collected from 11 localities of the Brazilian Cerrado region were investigated by GC-MS. Sabinene, limonene, biclyclogermacrene, beta-phellandrene and 1,8-cineole were the principal constituents. The results were submitted to principal component and chemometric cluster analysis which allowed three groups of essential oils to be distinguished with respect to the content of p-mentha-2,4(8)-diene, limonene/beta-phellandrene/gamma-terpinene and germacrene D/bicyclogermacrene. In patterns of geographic variation in essential oil composition indicated that the sesquiterpenes are mainly produced in the samples grown at lower latitudes.

S.A.M.U. 51 practises thrombolysis in patient's house associated with cardiologists of the University Hospital and of a Private Hospital, in indication and following for treatment. This way of working gives a large security for using this therapeutic to the whole population whatever the chosen hospital.

A case of Flumequine poisoning is described; a 13-year-old girl was admitted for a psychiatric syndrome. 3 hours after, seizures, coma, and metabolic disorders were observed. Infectious, encephalitic or diabetic diseases were suspected, but not confirmed. After 12 hours of a symptomatic treatment, the clinical status improved and the patient was discharged. At that time a tablet was found in her bedroom and a mas spectrographic analysis was positive for Flumequine. This case report is in agreement with previous observations and confirms the small therapeutic index of quinolone, and the absolute necessity to assess carefully a psychiatric diagnosis.

Available data on cancer rates in Madagascar are given. Cervical cancer is the most common, accounting for 28% of diagnosed tumours and 47% of genital tumours in women. It occurs most often in women of about 40 years of age. Penile cancer represents 5.2% of male tumours but occurs at different rates in various ethnic groups. Kaposi's sarcoma is rare in Madagascar. Equally hepatocellular carcinoma occurs at a low incidence in this country and is found most frequently in males over the age of 40 years. Cancer control programmes and the problems they encounter are also discussed.
