Neuroleptic malignant syndrome occurring in a suspected case of systemic lupus erythematosus

The case of a 40 year old female patient of SLE who developed fatal neuroleptic malignant syndrome following administration of serenase (haloperidol) is reported. Relevant literature has been reviewed.     

Risk factors of threshold retinopathy of prematurity

OBJECTIVE: To determine the risk factors which predispose to the development of threshold retinopathy of prematurity among patients of retinopathy of prematurity. METHODS: The ROP clinic records of a 3 year period were retrospectively studied to identify babies with threshold ROP (T-ROP) and sub-threshold ROP (ST-ROP). Various antenatal and perinatal risk factors, neonatal morbidity and therapeutic interventions were compared between the 2 groups. RESULTS: Of the total of 108 babies, 55 had T-ROP and 53 had ST-ROP. On univariate analysis, packed cell transfusions for anemia, double volume exchange transfusions (DVET), number of DVET, ventilation, gestational age 相似文献   

Heat distribution and heat transport in bone during radiofrequency catheter ablation

BACKGROUND: To assess the feasibility of percutaneous radiofrequency ablation in large bone tumours, the heat distribution in cortical bone and marrow around inserted electrodes was measured. METHODS: Fresh bovine cadaver tibial bones were locally heated through drill holes for a maximum of half an hour using water-cooled single radiofrequency electrodes (Radionics Instruments Inc) by pulsed energy. Temperatures were measured in the marrow canal as well as in cortical bone by thermocouples at various distances from the inserted probes. RESULTS: Perpendicular to the probe, hyperthermia of more than 50 degrees C could be created in bone marrow in a sphere of approximately 3 cm, and of approximately 1 cm in cortical bone. CONCLUSION: As irreversible cellular damage can be expected when increasing the temperature to 50 degrees C for a duration of 6 min, this method may be effective for the minimal invasive ablation of neoplasms within human bone in cigar-shaped regions of approximately 3-cm diameter.     

Programme planning and screening strategy in retinopathy of prematurity

Retinopathy of Prematurity (ROP) is one of the major emerging causes of childhood blindness. A well organised screening strategy and timely intervention can to a large extent prevent blindness due to ROP. This communication proposes a screening strategy and management plan to develop a model for the care of babies with ROP.

An evaluation of medical college departments of ophthalmology in India and change following provision of modern instrumentation and training

AIM: To evaluate teaching and practice in medical college ophthalmology departments in a representative Indian state and changes following provision of modern instrumentation and training. STUDY TYPE: Prospective qualitative study. MATERIALS AND METHODS: Teaching and practice in all medical colleges in the state assessed on two separate occasions by external evaluators. Preferred criteria for training and care were pre-specified. Methodology included site visits to document functioning and conduct interviews. Assessments included resident teaching, use of instrumentation provided specifically for training and standard of eye care. The first evaluation (1998) was followed by provision of modern instrumentation and training on two separate occasions, estimated at Rupees 34 crores. The follow-up evaluation in 2006 used the same methodology as the first. RESULTS: Eight departments were evaluated on the first occasion; there were 11 at the second. On the first assessment, none of the programs met the criteria for training or care. Following the provision of modern instrumentation and training, intraocular lens usage increased dramatically; but the overall situation remained essentially unchanged in the 8 departments evaluated 8 years later. Routine comprehensive eye examination was neither taught nor practiced. Individually supervised surgical training using beam splitters was not practiced in any program; neither was modern management of complications or its teaching. Phacoemulsification was not taught, and residents were not confident of setting up practice. Instruments provided specifically for training were not used for that purpose. Students reported that theoretical teaching was good. CONCLUSIONS: Drastic changes in training, patient care and accountability are needed in most medical college ophthalmology departments.
