[Misdiagnosed PTSD and zeldox pharmacotherapy in case of a political prisoner].

Treatment of survivors of political terror is an emerging and difficult field. Reports on posttraumatic stress disorder (PTSD) in political prisoners within the former Eastern Block countries is low and mostly restricted to German sources. During the totalitarian period administrative and clinical decisions often had to take into account political realities not found in other treatment environments. That practice might have lead to biased professional training, lack of experience extending into the post-communist era and leading to current underpresentation of PTSD. The authors present a case report of a Hungarian political prisoner with long history of PTSD who had a "carry over" diagnosis of paranoid schizophrenia even 15 years after the collapse of the communist regime. After decades of continuous administration of antipsychotic and antidepressive medications, either alone or in combination, Zeldox monotherapy has proven to be the most effective treatment for this patient.

[Preparedness for terrorist attack in the United States--the role of forensic pathologists and medical examiners].

Long distance airplanes hijacked by terrorists suddenly struck the World Trade Center in New York City on September 11, 2001. The city responded with efficient emergency service and there were a number of learning points for future planning. Early activation of the Disaster Mortuary Operation Response Team (DMORT) provided efficient family assistance by setting up a comprehensive Information Database Center and assisted the Medical Examiner in identifying the deceased. DMORT is a federally funded emergency service, made up of volunteer medical examiners and mortuary personnel, which responds to assist the local medical examiners in just such overwhelming emergency situations. We had been warned that Los Angeles was targeted as a probable site for similar attacks by terrorist groups. In response, Los Angeles has setup a far more advanced response system, the Coroner's Special Operation Response Team (SORT). SORT consists of over ten specialized units, one of which is the Weapons of Mass Destruction (WMD) Unit, staffed by qualified personnel, which provide continuing training, using standard procedures, drills and maintenance of many specialized protective equipment. Current urgent preparedness training includes the plans for maintaining government business continuity, safe keeping of electronic records, handling of multiple, widely spread fatalities through wrap, tag and hold program at multiple sites, using body bag, tag and hold procedure. Staff recruitment and training, development of equipment with the newly designed mobile facility for long range storage and field operation is an ongoing process in order to be able to respond effectively to any disaster. We still need expansion of training and equipment for handling cases of exposure to chemicals, biologic agents, radiation and nuclear energy. Plans in process are to have integration with DMORT and establish advance geographic information system, accomplished through the internet, and provide field reporting, commands and resource coordination in real time.

The 2003 SARS outbreak: global challenges and innovative infection control measures.

In early 2003, the global infection control community faced a great challenge, sudden acute respiratory syndrome (SARS). The rapid spread of SARS, its capacity to infect health care workers, and its many unknown features in the early days of the outbreak meant that health care workers were unsure of the most effective methods of infection control to prevent disease transmission. These conditions made designing appropriate, effective and standard infection control responses difficult. Innovation was necessary. This article provides a brief overview of global challenges in infection control and SARS. The author reports field observations and describes five selected examples of highly innovative, SARS-related infection control practices observed in three affected countries during the height of the 2003 outbreak. These examples relate to risk assessment, patient segregation, strategies to limit access to clinical areas, health care worker protection, and efforts to promote public confidence. Many of these strategies could be considered for use in the post-2003 SARS era, especially in preparation for an influenza or Avian influenza pandemic.

Production and standardization of polyvalent Clostridium perfringens vaccine in Iran.

In this presentation an account of the large-scale production and the standardization of polyvalent Clostridium perfringens vaccine in Iran is described. Over 20 million doses of this vaccine are produced and utilized in Iran every year. Certain modifications have been made to the culture media used in our laboratory for the production of this vaccine in order to bring down its cost. The prepared vaccine is highly immunogenic as determined by the laboratory examination on the quality of the vaccine according to British Veterinary Codex and the field reports.

The effects of individual and nursing-unit characteristics on willingness to adopt an innovation. A multilevel analysis.

In this study, the authors investigate the effects of efficacy and cooperativeness on willingness to adopt an innovation at the individual and nursing-unit levels. The results of a field report showed that efficacy was significantly associated with willingness to adopt an innovation at both the individual and nursing-unit levels, whereas cooperativeness was significant only at the individual level. These results suggest that examining innovation adoption at multiple levels provides more valid information than does examining it at a single level.

Prostatic intraepithelial neoplasia and atypical adenomatous hyperplasia. Relationship to pathologic parameters, volume and spatial distribution of carcinoma of the prostate.

OBJECTIVE: To summarize studies that have investigated the morphologic, spatial and volumetric relationship between prostate cancer and its putative precursors, high grade prostatic intraepithelial neoplasia (HGPIN) and atypical adenomatous hyperplasia (AAH). METHODS: Studies addressing the relationship between morphologic parameters of prostate cancer (i.e., stage, grade, volume and anatomic distribution) and both HGPIN and AAH are reviewed. Similar data based on our institutional experience with surgical and autopsy series of step-sectioned, totally embedded prostate glands are also presented. RESULTS: Most investigators have demonstrated significant associations between HGPIN and carcinoma in terms of coexistence, "zonal" origin and physical proximity. The two lesions have a high tendency to be present simultaneously; both originate predominantly in the peripheral zone and are often found within the same microscopic field. Reports on the relationship between HGPIN and the stage of prostate cancer are less consistent, and the associations of this lesion with cancer grade and volume are exceedingly complex. HGPIN appears to be associated with moderately to poorly differentiated, smaller, often-multifocal tumors and is less frequent in large, high grade cancers. There are data suggesting a trend-of a reciprocal relationship between more extensive and diffuse HGPIN and large-volume prostate cancers. Conversely, there is a wide spectrum of volume distribution of the two lesions in glands harboring smaller tumors. Similar data concerning AAH are limited. CONCLUSION: There are strong and consistent data supporting various aspects of the morphologic associations between HGPIN and prostate cancer. The indications that glands harboring larger tumors tend to contain less extensive HGPIN could raise the hypothesis that as carcinoma becomes larger, it may replace areas of the gland previously occupied by HGPIN. Alternatively, prostate cancer can evolve from ducts with HGPIN and gradually overgrow their precursor. There is a relative dearth of similar information concerning AAH.

Sevoflurane and the 885A field anesthesia machine: clinical report.

The Ohmeda 885A field anesthesia machine is equipped with a non-agent-specific, universal vaporizer that can be used with most volatile anesthetic agents. On a recent humanitarian medical mission to Honduras, the 885A was used to administer general anesthesia to 26 patients utilizing sevoflurane, a new inhalational anesthetic with a variety of clinical benefits, including less airway irritability, making it ideal for inhalation inductions. Flow rates for delivery of anesthetic agent were calculated by using the enflurane portion of the Verni-Trol flow calculator wheel, because sevoflurane and enflurane have similar vapor pressures. Calculated anesthetic concentrations were compared with measured concentrations using linear regression analysis and found to have a Pearson product moment of 0.995. We find that the use of sevoflurane in the 885A is an excellent alternative to other inhalational anesthetic agents and may have applications for use during both military conflicts and peacetime missions in remote areas.

Manure Enhances Plasmid Mobilization and Survival of Pseudomonas putida Introduced into Field Soil.

We report a field study on plasmid mobilization in an agricultural soil. The influence of pig manure on the mobilization of the IncQ plasmid pIE723 by indigenous plasmids or by the IncP(alpha) plasmid pGP527 into the recipient Pseudomonas putida UWC1 (Rif(supr) Nal(supr)) was studied in field soil. Six plots were prepared in duplicate, three of which were treated with manure prior to inoculation of the donor and recipient strains. As a donor strain, either Escherichia coli J53(pIE723) or E. coli 600(pIE723, pGP527) was used. Putative transconjugants obtained on a selective medium were confirmed by DNA hybridization and PCR. Plasmid mobilization by indigenous mobilizing plasmids was observed on two occasions in manured soil. Manuring of soil significantly enhanced the frequency of pIE723 mobilization by pGP527, since mobilization frequencies into P. putida UWC1 were at least 10-fold higher in manured soil than in nonmanured soil. Enhanced numbers of P. putida UWC1 transconjugant and recipient colonies could be observed in manured soil throughout the 79-day field test. Transfer of pIE723 or pG527 into indigenous soil or rhizosphere bacteria could not be detected when indigenous bacteria isolated by selective cultivation were screened for the presence of these plasmids by DNA hybridization. Furthermore, the presence of IncN-, IncP-, or IncQ-specific sequences was confirmed in total community DNA extracted directly from the manured or nonmanured soil by PCR. IncW plasmids were detectable only in manured soil, indicating entry of these plasmids into soil via manure.

The practice of nurse-midwifery in the era of managed care: reports from the field.

OBJECTIVE: The purpose of this paper is to describe the reports of certified nurse-midwives (CNMs) about how changes in the financing and organization of health care in the late 1990s influenced their ability to serve vulnerable populations and provide a woman-centered, prevention-oriented midwifery model of care. METHODS: A 13-page survey was mailed to all CNMs ever certified by the American College of Nurse-Midwives (N = 6365) in July 1998. The survey included closed- and open-ended questions. A total of 2405 CNMs responded: of these, 2089 were in clinical practice during the study period (1997-98) and 82% of the 2089 (N = 1704) wrote responses to the open-ended questions and were included in the qualitative database. We present responses to the closed-ended questions about seven domains of practice and elaborate on three major themes identified through content analysis of the qualitative data. RESULTS: The majority (57%) reported that the changes in the larger health care environment had influenced their practices during 1997-98. The effects most frequently reported were 1) increased client loads (31%); 2) altered style of practice (30%): 3) inability to serve the same populations; (20%); 4) decreased client loads (20%); and 5) increased administrative duties (17%). Three major themes were identified and elaborated upon in the qualitative data: 1) challenges to the style of midwifery practice related to the managed care environment; 2) the loss of socially and economically at-risk women from CNMs' client base; and 3) barriers to high quality and comprehensive services for women. CONCLUSIONS: During the late 1990s as managed care was expanding and health systems were merging, a significant number of CNMs in the field described threats to their ability to sustain economically viable practices and a style of care consistent with the woman-centered, prevention-oriented midwifery model.

Absolute ionization rates of multielectron transition metal atoms in strong infrared laser fields.

We report on nonresonant strong field ionization of the multielectron transition metal atoms V, Nb, Ta, Ni, and Pd. Operating in the adiabatic regime (lambda = 1.5 microm), we quantitatively determined both (i) the first charge state saturation intensities and (ii) the absolute ionization rates for intensities ranging from threshold up to 3 x 10(14) W/cm2. We observed a dramatic suppression of ionization relative to single active electron approximation expectations. We suggest that this derives from dynamic polarization or screening effects within the multielectron atom, stressing a need for many-body theories of strong field ionization.

A FIELD trial of freeze-dried glutamate BCG vaccine; preliminary report.

A field trial of dried BCG vaccine prepared with sodium glutamate as adjuvant was carried out by the WHO/UNICEF Tuberculosis Survey Team for West Africa in Ilorin, Nigeria, in April 1956. This trial-the first of a series of studies being undertaken jointly by the WHO Tuberculosis Research Office and the Japan Anti-Tuberculosis Association-was designed to test the heat-stability of the new dried vaccine.The allergenic potency six months after vaccination of two different lots of glutamate vaccine stored under various temperature conditions was compared with that of a batch of fresh liquid vaccine stored at 2-4 degrees C. The results showed both lots of dried vaccine to be remarkably heat-stable: even after 30 days' exposure to tropical temperatures, no marked loss of allergenic potency was observed.

AUR memorial Award. Induced alignment of flowing sickle erythrocytes in a magnetic field. A preliminary report.

Deoxygenated sickle erythrocytes in static suspension align perpendicular to a magnetic field. To assess the importance of this observation to MRI of sickle-cell disease, an in vitro flow apparatus was devised and the orientation of sickle erythrocytes flowing through a 0.38 T magnetic field was investigated. We showed a significant perpendicular alignment of fully deoxygenated sickle erythrocytes flowing at 3 to 4 mm/minute (P less than .001). These results suggest that deoxygenated erythrocytes in a sickle-cell patient could orient perpendicular to a magnetic field, and therefore that MRI of such patients could possibly result in worsening of vaso-occlusive complications. Further studies are needed to assess the possible hazards of MRI of sickle-cell disease, especially at high field strengths.

EX SAIF SEREEA II--the field hospital clinical report.

This paper places on record the clinical activity of the hospital facilities run by 22 Field Hospital on Exercise SAIF SEREEA II in Oman from August to November 2001. There were 1322 episodes of illness resulting in a hospital admission. The mean rate of admission was 1.96 patients per thousand per day (SD 13.62). The main causes of admission were gastrointestinal illness, conditions related to the heat and injuries. The reporting of health service utilisation data is an important duty of medical personnel during overseas deployments in order to add to the dataset available for the estimation of medical workload for future operations.

[Health Council Report 'Radiofrequency electromagnetic fields (300 Hz-300 GHz). The Health Council of the Netherlands].

The Health Council of the Netherlands in 1997 issued a report updating the guidelines for maximum acceptable exposure to radiofrequency electromagnetic fields formulated in 1975. The new recommendations are based on thermal effects for frequencies over 10 MHz. The committee considers the results of studies indicating non-thermal effects such as direct damage to DNA, not reliable enough to be used in setting exposure limits. Electromagnetic interference by electromagnetic fields generated by hand-held telephones may indirectly result in threats to health if vital medical equipment is affected. The committee advises people wearing an implanted pacemaker not to carry a portable telephone that is in stand-by mode in close proximity to the pacemaker; a minimum distance of 15 cm should be observed.

Reversal of delayed union of anterior cervical fusion treated with pulsed electromagnetic field stimulation: case report.

We present a case report of anterior cervical fusion non-union that was successfully treated with pulsed electromagnetic field (PEMF) stimulation. In this case, a C6-C7 nonunion was identified clinically and radiographically 1 year after surgery. Imaging revealed nonunion with partial resorption of the bone graft compared with imaging studies performed 8 months earlier. The patient wore a PEMF stimulation device for 3 h/d for 10 months. After 3 months of treatment, the patient's symptoms were resolved. X-rays obtained after 15 weeks of stimulation showed improvement in bone fusion, and x-rays obtained at 31 weeks after stimulation showed even bone density around the C7 screws. The patient remained symptom-free 13 months after the termination of PEMF stimulation at last assessment. PEMF stimulation demonstrated its clinical potential in healing established nonunion of anterior cervical spine fusion. Its use is noninvasive and can be considered an alternative to surgical intervention in selected patients.

Measurement of the threshold sensitivity of honeybees to weak, extremely low-frequency magnetic fields

Experiments reported previously demonstrate that free-flying honeybees are able to detect static intensity fluctuations as weak as 26 nT against the background, earth-strength magnetic field. We report here an extension of this work to weak, alternating fields at frequencies of 10 and 60 Hz. Our results indicate that the sensitivity of the honeybee magnetoreception system decreases rapidly with increasing frequency. At 60 Hz, alternating field strengths above 100 µT are required to elicit discrimination. These results are consistent with biophysical predictions of a magnetite-based magnetoreceptor.
