ROLE OF EPIDURAL MEDICATION IN LUMBOSCIATIC SYNDROME

Role of epidural medication through caudal route was studied in 109 patients having lumbago with or without sciatica to highlight the value of this mode of treatment which relieved symptoms in more than 70% of cases without hospitalisation and without being off work for long periods as in usual methods of conservative treatment.KEY WORDS: Epidural medication, Backache, Lumbago, Sciatica     

Repetition Strain Injury--a Recent Review

The Repetition Strain Injury (RSI) is an umbrella term coveringseveral conditions. It consists of the soft tissue disordersinvolving the tendons, nerves and the periarticular structuresin the upper extremity and neck. The risk factors are physical,psychological and ergonomic and sometimes influenced by variedconfounding factors. The evaluation of RSI should be based notonly on the clinical diagnosis but also on the detailed analysisof the job. The primary objective for the management is preventionand the strategies should include appropriate engineering controland the organization of the work systems and the personnel functions.

Management of zygomatic complex fracture in armed forces

Introduction: The Armed Forces personnel are exposed to various kinds of injuries due to the nature of their duties. Increase in motorized population without taking protective measures and rise in violence has contributed towards maxillofacial injuries. The aim of this study was to determine the incidence, aetiology and management of injuries resulting in fracture of the Zygomatic complex in Armed Forces personnel and their families.     

激光小角光散射仪测定右旋糖酐分子量

激光小角光散射仪(LALLS)由于采用了激光光源,具有光强度高、单色性强、准直性好等特点,可以在微量样品池及很低浓度的溶液中进行小角度(3°～7°)散射光强的测量,溶质的瑞利系数与其分子量有如下关系:     

Haemodynamic Studies During the Management of Severe Tetanus

Detailed invasive haemodynamic studies were performed in 27of 32 patients with severe tetanus. Nineteen had severe uncomplicatedtetanus and eight had associated major complications, chieflyinfection and pulmonary complications. The results were comparedwith those obtained from 15 healthy male volunteers who servedas controls. There were two deaths in 32 patients (mortality6.25 per cent). Severe tetanus without major complications wascharacterized by a high output hyperkinetic circulatory statewith tachycardia (heart rate 131 (19.2) beats/minute), increasedstroke volume index (43.1 (10.7) ml/m²), increased cardiac index(5.48 (0.94)1/min/m²) and a normal left ventricular stroke workindex (60.5 (15.9) g/m/m²). Volume loading demonstrated a significanthaemodynamic response and increased vascular capacitance. Evenso the maximum percent rise from baseline values of these indicesafter volume load was significantly higher in controls (p <0.001). Autonomic cardiovascular disturbances affected bothsympathetic and parasympathetic activity. Hypertension and tachycardiaalternating with hypotension and bradycardia were related tosudden fluctuations in systemic vascular resistance. Our studiessuggested some degree of myocardial dysfunction in patientswith severe uncomplicated tetanus. The haemodynamics of severetetanus were masked and altered by complicating infection, pneumonia,and atelectasis.     

Unknown poisoning amongst serving personnel

Background: Poisoning is recognized as an important health problem in many countries of the world. There is incomplete information on poisoning accidents, which is a major problem in developing countries.
