[Sources of hazards in laparoscopic colon surgery and how to avoid them].

From May 1993 to September 1994 98 patients with colon pathology were operated with the laparoscopic method. Criteria for exclusion were: patient's wish, tumor size or tumor infiltration in adjacent organs. The resection was carried out strictly according to the guidelines of open surgery. All operations were performed by two laparoscopically experienced visceral surgeons. All routine colon operations were included. The conversion rate was 13%. The rate of anastomotic leakage was 3.5% in both laparoscopic completed resections as well as in left-sided resections, which is comparable to the rate found in open resections. The rate of stenosis, showed a similar finding amounting to 3.5%. A complication subject to laparoscopic surgery occurred in one of our early cases, namely the severing of the ureter, this complication can be avoided with sufficient experience. Furthermore a portside hernia (1.2%) was due to laparoscopy and can be avoided as well by accurate suture of the trocar incisions. Initial postoperative hemorrhage (n = 4, one of which required operative revision) were no longer observed with increasing experience and careful choice of the trocar incision sites. An initially increased rate of wound infections could be reduced substantially by using a wound-protecting device during surgery. Laparoscopic colon resection is a safe method, which has a reduced rate of relevant complications in comparison to open procedures. Prerequisite for success is optimal technical equipment, an experienced and well coordinated team, and the understanding that conversion to an open procedure is not to be considered a complication.

Deterrence of biological and chemical warfare: a review of policy options.

The deployment of biological and chemical weapons by aggressor states is not a hypothetical scenario but a life-threatening contingency. Although Iraq was deterred from using its biological and chemical weapons during Operation Desert Storm, what forms of deterrence must be considered in preventing the use of these weapons of mass destruction in the future? Traditional deterrents against their use have ranged from the threat of a military response to the ratification of diplomatic treaties and agreements. An overall strategy to deter the use of these weapons includes an additional, less frequently discussed approach-force protection-which encompasses defensive biomedical countermeasures (e.g., antibiotics, drugs, vaccines, diagnostic tests) and nonmedical protective devices (e.g., masks, specialized clothing/shelters, detectors). A combined, integrated approach to deterrence is reviewed in this article with regard to current policies and the roles played by Department of Defense research and development programs for biological and chemical defense.

Tendons and ligaments--an overview.

The structure, range of functions, blood supply, nerve supply, biochemical composition and development of tendons and ligaments are reviewed. The importance of their cells is often overlooked because of the obvious role of the extracellular matrix (ECM) in determining the physical properties of tendons and ligaments. However, it is emphasised that tendon and ligament cells have elaborate cell processes that form a three dimensional network extending throughout the extracellular matrix. The cells communicate with each other via gap junctions that could form the basis of an important load sensing system allowing the tendon to modify its ECM. Tendons and ligaments have three specialised regions along their length-the myotendinous junction, the region where tendons change direction by wrapping around bony pulleys and the enthesis (bony insertion site). The myotendinous junction is a common site of muscle strains and pulls, the wrap-around region is frequently fibrocartilaginous and a common site for degenerative change, and the enthesis may be fibrous or fibrocartilaginous according to location, and is a common site for degenerative changes or 'enthesopathies'. Enthesis fibrocartilage is just one of a series of protective devices reducing wear and tear at insertion sites. Consideration is also given to the structure and function of tendon sheaths and to the dramatic effects of exercise and deprivation on tendons and ligaments-exercise strengthens, but even relatively short periods of immobilisation can dramatically weaken tendons and ligaments.

Working and living conditions of construction workers: comparison between large and small construction sites in northeastern Thailand.

This study examined differences in working and living conditions of construction workers in large and small construction sites in Northeastern Thailand. Data were collected by questionnaires, through observation and interviewing. A total of 812 construction workers from 20 large sites and 24 small sites were studied. Working and living conditions among the construction workers were generally poor. However, they were better at the large sites than the small ones. The data suggest an urgent need to improve sanitation and safety conditions on the construction sites and camp sites, including personal protective devices and improved welfare for the workers and their families.

[Topical problems of hygienic certification of computers].

The paper provides evidence that while making a hygienic certification of computers it is necessary to rely not only on their physical and technical data, but on the characteristics obtained by defining the integral physiological parameters of the quality of displayed information perception. According the state standards CaH [symbol: see text] 2.2.2.54-96, their hygienic certification requires differential assessment of computers with the age-specific features of users (pre-school and young school children, middle- and old-aged schoolchildren, adults). It is proposed that CaH [symbol: see text] 2.2.2.54-96 should be supplemented by a regulation on choice of special working places with appropriate protective devices for the children of a risk group.

[Eye injuries caused by lasers in military and industrial environment. Apropos of 13 cases].

PURPOSE: The aim of this study was to analyse the nature of wavelengths used by military forces, evaluate their clinical consequences in terms of ocular risk, and determine the therapeutic implications and specific preventative measures which should be implemented both in peace- and war-time-settings. MATERIAL AND METHODS: We analyzed retrospectively 13 cases of laser injury (12 patients) treated in our unit over the past 10 years. We recorded the characteristics of the responsible lasers, effects on visual acuity and visual filed, initial ophthalmoscopic and angiographic aspects, treatment undertaken and patient follow-up. RESULTS: Wavelengths were know in only 10 cases. In 9 cases a NdYag laser operating at 1063 nm was involved. The tenth case was an Argon Coirorint laser accident. In three cases the wavelength could not be ascertained because it was confidential information or had been emitted by the enemy and had not been identified. Ocular injury was bilateral in 1 case and unilateral in 12. Retinal lesions were foveolar in 8 cases with an initial visual acuity varying from 1/10 to 10/10. Visual loss depended on the extent of the burn and did not tend to improve despite vasoprotector and corticosteroid treatments. In 2 cases the injury progressed without formation of an epimacular membrane. Retinal lesions were extra-foveolar in 5 cases and in 1 case vitreous hemorrhage required vitrectomy. CONCLUSION: With the widespread use of Yag lasers and the soon to be employed tuneable lasers, there in major risk of serious ocular injury resulting from foveolar burns or peripheral retina trauma with vitreous hemorrhage. In a war situation, a large number of laser casualties producing peripheral vitreous hemorrhage would create an important logistics problem for vitrectomy. The accent must therefore be focused on prevention. Personnel must be informed of the danger and instructed in wearing filter glasses adapted to the wavelengths being used, if known, or a universal photoactivated protective device, as yet a hypothetical possibility.

Bicycle safety equipment.

It is important for the physician to understand bicycle safety equipment in order to prevent and treat bicycle-related injuries effectively. The physician should understand (1) the basic design and function of bicycles, (2) the relationship of improper bicycle fit to injuries, (3) the potential of the various forms of serious riding and racing for injury, and (4) bicycle safety equipment and the standards involved in its fit, manufacture, and care. A decision to use bicycle safety equipment is a decision to control the risk of injury. Physicians should accept a share of the responsibility for decreasing bicycling-related injuries, because they are viewed by the public as credible sources of information regarding the prevention of accidents and injuries.

Distal protection with a filter device during coronary stenting in patients with stable and unstable angina.

BACKGROUND: Filter protection after percutaneous coronary intervention (PCI) is now available to prevent distal embolization. The aims of this study were (1) to evaluate the microembolization phenomenon during procedures of stent implantation in native coronary arteries of patients with stable and unstable angina, (2) to assess the amount and characteristics of the debris captured by the Angioguard, and (3) to investigate the relation between clinical and angiographic variables and pathological data. METHODS AND RESULTS: Elective coronary stenting with the use of a protective filter was attempted in 39 consecutive coronary artery lesions with >60% stenosis (mean, 67.6+/-8.79%). Debris was present in 75.6% of the filters. Particle size ranged from 47.16 to 2503.48 microm (mean, 518.83+/-319.61 microm) in the major axis. Particles >300 microm were found in 24 of 28 filters with debris (85.7%), and particles >1000 microm were present in 10 of 28 filters (35.7%). Patients with unstable angina had greater particles (mean maximum longitudinal diameter, 1098.33+/-714.3 microm) than those with stable angina (412.91+/-453 microm; P<0.001). The presence of unstable angina (OR, 65; CI, 1.2 to 3420; P=0.03) and age >67 years (OR, 42; CI, 1 to 1698; P=0.04) were found to be the only independent predictors of embolic particle size. CONCLUSIONS: By limiting embolization, protective devices may prevent a number of potentially unfavorable events, thereby improving outcome. Our data support the use of these devices, especially in lesions with higher embolic potential, such as those occurring in older patients and in those with unstable angina.

Two simple leg net devices designed to protect lower-extremity skin grafts and donor sites and prevent decubitus ulcer.

Burn therapists routinely are tasked to position the lower extremities of burn patients for pressure ulcer prevention, skin graft protection, donor site ventilation, and edema reduction. We developed two durable and low-maintenance devices that allow effective positioning of the lower extremities. The high-profile and low-profile leg net devices were simple to fabricate and maintain. The frame was assembled using a three-quarter-inch diameter copper pipe and copper fittings (45 degrees, 90 degrees, and tees). A double layer of elasticized tubular netting was pulled over the frame and doubled back for leg support to complete the devices. The devices can be placed on any bed surface. The netting can be exchanged when soiled and the frame can be disinfected between patients using standard techniques. Both devices were used on approximately 250 patients for a total of 1200 treatment days. No incidence of pressure ulcer was observed, and graft take was not adversely affected. The devices have not required repairs or replacement. Medical providers reported they are easy to apply and effectively maintain proper positioning throughout application. Neither device interfered with the application of other positioning devices. Both devices were found to be an effective method of positioning lower extremities to prevent pressure ulcer, minimize graft loss and donor site morbidity, and reduce edema. The devices allowed for proper wound ventilation and protected grafted lower extremities on any bed surface. The devices are simple to fabricate and maintain. Both devices can be effectively used simultaneously with other positioning devices.

Eye health of industrial workers in Southeastern Nigeria.

A cross-sectional ophthalmological survey to determine the ocular health in Nigerian industries was undertaken in four randomly selected industrial establishments in Enugu State of Nigeria. The industrial establishments studied were the cement factory, coal mine, saw mill and iron/steel works where motor spare parts are fabricated. Of the 646 workers, 184 (28.5%) had a history of industrial accidents, 81 (12.5%) of which affected the eye. Eye injury was most commonly caused by metal chips, cement dust, fragments of wood, pieces of coal stone and welders' arc rays all of which could be prevented by wearing appropriate protective eye coverings. Contusion injury was the most common type of injury reported. Eye accident rate varied from factory to factory as also did the wearing of protective eye devices. overall, the percentage of workers using protective eye cover was 16.7% but there was a significant difference between the factories in this respect, protective eye wear being more often used in factories with higher eye accident rates. A total of 646 technical workers had detailed ophthalmological examination. The types and frequencies ofvisual disorders seen as well as the nature and causes of eye injuries were determined. Five hundred and twenty-eight workers (81.7%) had eye disorders. Presbyopla was responsible for 203 (31.4%) of these disorders while 169 (26.2%) were refractive errors. Of the others, pterygium and pingueculum together numbered 179 (27.7%) while cataract was found in 79 (12.2%) subjects. The results showed a high frequency of eye injuries among industrial workers and a low level of use of protective eye cover while at work. It is recommended that legislation requiring the use of protective devices in high-risk industries should be vigorously enforced to improve the eye health of Nigerian industrial workers.

Cerebral protection during percutaneous carotid intervention: wich device should be used ?

Embolic complications remain the major and unpredictable clinical event during carotid angioplasty and stenting. Cerebral protection devices could play an important role in the prevention of such emboli. Protection devices such as occlusion balloons, filters and reversed flow devices are currently undergoing clinical evaluation and appear to be promising in reducing the incidence of embolic events. This article provides an overview of the three different types of embolic protection devices.

Inexpensive radiation protective glasses.

Using the services of a local optical supply house, fabrication and testing of eyeglasses of a high lead content that could be used to protect the eye from the hazards of radiation were evaluated. Two separate types of eyeglasses were manufactured (a prototype followed by a second pair), and these were tested against a commercially available pair of radiation protective glasses. The protection offered by the locally manufactured pair of glasses exceeded the commercial pair and the cost savings are significant.

Physical factors determining the utility of radiation safety glasses.

Ten types of lenses were tested for their radiation protection properties in three experimental circumstances: (a) Their good geometry (scatter free) attenuation was determined as a function of HVL in a direct x-ray beam. (b) Their dose reducing properties were determined under simulated clinical fluoroscopic conditions, using both ion chambers and thermoluminescent dosimeters (TLD's) while the lenses, mounted in frames, were worn by a head phantom. The head was oriented in four different directions to simulate clinical conditions in a fluoroscopic room. (c) Their dose reducing properties were measured with TLD's while the glasses were worn by radiologists during clinical fluoroscopic procedures. Although several of the lenses could attenuate a direct x-ray beam several thousand times, none of the glasses offer more than a factor of 8 reduction in eye exposure when the glasses are worn during fluoroscopy. This is attributed to backscatter from the fluoroscopist's head and deficient lateral shielding. Some of the glasses may even be causing an increase in eye exposure when the TV monitor is located 90 degrees or more from the patient.
