Measles outbreak associated with a preschool setting among partially vaccinated children in the Tel Aviv District, Israel, October 2023. Vaccine 2024; 42:3153-3156. [PMID: 38627149 DOI: 10.1016/j.vaccine.2024.04.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 03/07/2024] [Accepted: 04/04/2024] [Indexed: 04/29/2024]
Abstract
In October 2023, the Tel Aviv District was notified of ten cases of measles. The outbreak initiated in a preschool with high vaccination coverage with one dose of MMR vaccine. Serological testing was available for eight patients (six children and two adults). Among the six children vaccinated with one dose of MMR vaccine, primary vaccine failure was demonstrated. Among the adults, secondary vaccine failure was confirmed. The outbreak was successfully contained due to a combination of factors, notably its occurrence within a population characterized by high vaccination coverage in Tel Aviv, during a period of restricted public interactions due to the prevailing state of war in the country. Despite challenging wartime conditions, effective prophylactic measures were promptly executed, encompassing a 2-dose MMR vaccination schedule for close contacts and the broader community of children in the TA district, successfully curbing the outbreak and preventing widespread infections.

Abstract
Background There are limited data regarding the long-term health effects of child survivors of the 2013-2016 West African Ebola virus disease (EVD) outbreak. Here, we assess post-Ebola sequelae among EVD child survivors by comparing the self-reported symptoms between EVD child survivors and their close household contacts over one year after the end of the outbreak. Methods EVD child survivors(n=159) and their close contacts(n=303) were enrolled in Western and Eastern Sierra Leone. Demographics and self-reported symptoms data were collected using an interviewer-administered questionnaire. We compared a list of self-reported symptoms between EVD child survivors and their close household contacts using backward stepwise logistic regression. Results EVD child survivors were more likely to be orphans compared to their close contacts. Musculoskeletal, ocular, auditory and neurological symptoms were more prevalent among Ebola child survivors than their close contacts (p<0.001). Joint pain and headache were the most common self-reported symptoms in EVD child survivors and their close contacts. Joint pain (AOR=2.633; 95 % CI:1.31-5.28, p=0.006), eye pain (AOR=4.56;95 %CI: 2.16-9.64, p<0.001), hearing loss (AOR=3.85; 95 %CI: 1.15-12.87, p=0.029), memory impairment (AOR=7.76;0.95 %CI: 1.34-45.01 p=0.022), mood changes (AOR=5.07; 95 %CI: 2.35-10.94, p<0.001) were more common among survivors than their contacts. Conclusions Our data suggest that EVD child survivors have higher odds than their close contacts of suffering from musculoskeletal, ophthalmic, auditory and neurological impairment more than a year after the end of the EVD outbreak. Routine screening, treatment and monitoring of these symptoms is required to prevent long-term disability among EVD child survivors.

Inferring Numbers of Wild Poliovirus Excretors Using Quantitative Environmental Surveillance. Vaccines (Basel) 2021; 9:870. [PMID: 34451995 PMCID: PMC8402366 DOI: 10.3390/vaccines9080870] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2021] [Revised: 07/22/2021] [Accepted: 07/29/2021] [Indexed: 01/19/2023] Open
Abstract
Response to and monitoring of viral outbreaks can be efficiently focused when rapid, quantitative, kinetic information provides the location and the number of infected individuals. Environmental surveillance traditionally provides information on location of populations with contagious, infected individuals since infectious poliovirus is excreted whether infections are asymptomatic or symptomatic. Here, we describe development of rapid (1 week turnaround time, TAT), quantitative RT-PCR of poliovirus RNA extracted directly from concentrated environmental surveillance samples to infer the number of infected individuals excreting poliovirus. The quantitation method was validated using data from vaccination with bivalent oral polio vaccine (bOPV). The method was then applied to infer the weekly number of excreters in a large, sustained, asymptomatic outbreak of wild type 1 poliovirus in Israel (2013) in a population where >90% of the individuals received three doses of inactivated polio vaccine (IPV). Evidence-based intervention strategies were based on the short TAT for direct quantitative detection. Furthermore, a TAT shorter than the duration of poliovirus excretion allowed resampling of infected individuals. Finally, the method documented absence of infections after successful intervention of the asymptomatic outbreak. The methodologies described here can be applied to outbreaks of other excreted viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), where there are (1) significant numbers of asymptomatic infections; (2) long incubation times during which infectious virus is excreted; and (3) limited resources, facilities, and manpower that restrict the number of individuals who can be tested and re-tested.

Earlier Outbreak Detection-A Generic Model and Novel Methodology to Guide Earlier Detection Supported by Data From Low- and Mid-Income Countries. Front Public Health 2020; 8:452. [PMID: 33014967 PMCID: PMC7516212 DOI: 10.3389/fpubh.2020.00452] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Accepted: 07/21/2020] [Indexed: 12/01/2022] Open
Abstract
Infectious disease outbreaks can have significant impact on individual health, national economies, and social well-being. Through early detection of an infectious disease, the outbreak can be contained at the local level, thereby reducing adverse effects on populations. Significant time and funding have been invested to improve disease detection timeliness. However, current evaluation methods do not provide evidence-based suggestions or measurements on how to detect outbreaks earlier. Key conditions for earlier detection and their influencing factors remain unclear and unmeasured. Without clarity about conditions and influencing factors, attempts to improve disease detection remain ad hoc and unsystematic. Methods: We developed a generic five-step disease detection model and a novel methodology to use for data collection, analysis, and interpretation. Data was collected in two workshops in Southeast Europe (n = 33 participants) and Southern and East Africa (n = 19 participants), representing mid- and low-income countries. Through systematic, qualitative, and quantitative data analyses, we identified key conditions for earlier detection and prioritized factors that influence them. As participants joined a workshop format and not an experimental setting, no ethics approval was required. Findings: Our analyses suggest that governance is the most important condition for earlier detection in both regions. Facilitating factors for earlier detection are risk communication activities such as information sharing, communication, and collaboration activities. Impeding factors are lack of communication, coordination, and leadership. Interpretation: Governance and risk communication are key influencers for earlier detection in both regions. However, inadequate technical capacity, commonly assumed to be a leading factor impeding early outbreak detection, was not found a leading factor. This insight may be used to pinpoint further improvement strategies.

Earlier detection of public health risks - Health policy lessons for better compliance with the International Health Regulations (IHR 2005): Insights from low-, mid- and high-income countries. Health Policy 2019; 123:941-946. [PMID: 31288952 PMCID: PMC7114645 DOI: 10.1016/j.healthpol.2019.06.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2018] [Revised: 06/02/2019] [Accepted: 06/18/2019] [Indexed: 11/29/2022]
Abstract
The International Health Regulations (IHR 2005) require all Member States to build and maintain the capacities to prevent, detect and respond to public health emergencies. Early detection of public health risks is one of the core functions. In order to improve surveillance and detection, a better understanding of the health system conditions and their influencing factors are needed. The Israeli Ministry of Health/IHR National Focal Point held a workshop to elucidate health system conditions and their influencing factors that enable earlier detection. The workshop methodology employed a stepwise, small working group analysis approach to elucidate the conditions and their influencing factors affecting each stage of recognition, assessment, and reporting of infectious disease outbreaks, at the local, regional and national levels. In order to detect public health risks earlier, the detection process needs to be moved closer to the local communities and start with building capacity within communities. Building capacity and engaging with local and diverse communities requires significant changes in the governance approach and include information sharing, multi-sectoral communication and coordination across various levels before, during and after public health emergencies. Across the regions, low-, mid- and high-income countries seem to struggle more with governance and information sharing rather than with technical capacities and capabilities.

Abstract
OBJECTIVE To explore the eating experience and eating-related quality of life (ERQOL) of community-dwelling older adults with tooth loss. METHOD Nineteen older adults from the clinics of a northeast US dental school who met inclusion criteria (>65 y old, <20 teeth, and no dentures) composed the sample. For this mixed methods study, demographic characteristics, number and location of teeth, Mini Nutritional Assessment-Short Form score, and anthropometrics data were collected; semistructured interviews were conducted to collect in-depth information about the eating experience and ERQOL. Thematic analysis was completed with NVivo 12 software (QSR International). RESULTS Participants' mean age was 71.3 y (SD = 5.2); 52.6% (n = 10) were women; 63.2% (n = 12) were Black or African American. The mean Mini Nutritional Assessment-Short Form score of 12.1 was reflective of normal nutrition status; 31.6% (n = 6) of patients were at risk for malnutrition or were malnourished. Fifteen percent (n = 3) were fully edentulous; 84.2% (n = 16) had 1 to 19 teeth (mean = 10.8, SD = 6.5). The 2 overarching themes identified were adaptive and maladaptive behavioral responses to tooth loss. Adaptive strategies included modification in food preparation and cooking methods, food texture selection, meal timing, and approaches to chewing. Maladaptive behaviors included food avoidance and limiting eating and smiling in front of others. Psychosocial factors, including finances, limited food choices and ERQOL, whereas the support of family and friends enhanced ERQOL according to participants. CONCLUSION Older adults with tooth loss exhibit both adaptive and maladaptive behaviors that affect their eating experience, dietary intake, and ERQOL. While many expressed positive adaptive coping strategies, they also described maladaptive behaviors, including avoidance of healthy foods and limiting eating during social interactions, which may affect their nutritional status and overall health and well-being. Further research is needed to explore how duration and severity of tooth loss influence these behaviors and risk of malnutrition. Interprofessional approaches are needed to support positive adaptation and coping with tooth loss. KNOWLEDGE TRANSFER STATEMENT The results of this study can be used by health professionals treating patients with tooth loss in an effort to improve their eating experience and eating-related quality of life. The findings provide data to support further studies and the need for evidence-based guidelines and educational materials to meet the unique needs of older adults with tooth loss.

Abstract
We report preliminary findings of a large outbreak of human leptospirosis with 36 confirmed/probable and 583 suspected cases from June-August 2018, linked to contaminated water bodies in Northern Israel. There was a travel-associated case in Germany; additional cases are being investigated in other countries. The presumed chain of transmission, implicating wild boar and cattle, raises multiple challenges for risk assessment, risk management and risk communication currently being addressed by a public health response team.

Abstract
In Israel, 262 mumps cases were registered between 1 January and 28 August 2017 despite a vaccine coverage of ≥ 96%. The majority (56.5%) of cases were adolescents and young adults between 10 and 24 years of age. Nearly twice as many cases were reported in males than in females. Sequence information identified genotype G and suggested specific transmission chains in different religious communities, with the Muslim population in Jerusalem being most severely affected.

Abstract
CBCT is a widely applied imaging modality in dentistry. It enables the visualization of high-contrast structures of the oral region (bone, teeth, air cavities) at a high resolution. CBCT is now commonly used for the assessment of bone quality, primarily for pre-operative implant planning. Traditionally, bone quality parameters and classifications were primarily based on bone density, which could be estimated through the use of Hounsfield units derived from multidetector CT (MDCT) data sets. However, there are crucial differences between MDCT and CBCT, which complicates the use of quantitative gray values (GVs) for the latter. From experimental as well as clinical research, it can be seen that great variability of GVs can exist on CBCT images owing to various reasons that are inherently associated with this technique (i.e. the limited field size, relatively high amount of scattered radiation and limitations of currently applied reconstruction algorithms). Although attempts have been made to correct for GV variability, it can be postulated that the quantitative use of GVs in CBCT should be generally avoided at this time. In addition, recent research and clinical findings have shifted the paradigm of bone quality from a density-based analysis to a structural evaluation of the bone. The ever-improving image quality of CBCT allows it to display trabecular bone patterns, indicating that it may be possible to apply structural analysis methods that are commonly used in micro-CT and histology.

Abstract
Israel was certified as polio-free country in June 2002, along with the rest of the World Health Organization European Region. Some 11 years later, wild-type polio virus 1 (WPV1) was isolated initially from routine sewage samples collected between 7 and 13 April 2013 in two cities in the Southern district. WPV1-specific analysis of samples indicated WPV1 introduction into that area in early February 2013. National supplementary immunisation with oral polio vaccine has been ongoing since August 2013.

Abstract
OBJECTIVES To determine whether addition of written-prescription data to existing adherence measures improves identification of nonadherent patients and prediction of changes in low-density lipoprotein (LDL) cholesterol. STUDY DESIGN Retrospective database analysis of all health plan members prescribed a statin in 2008 and followed through 2010. METHODS We examined statin use in a 4-millionmember health plan with 100% electronic medical record coverage. A novel type of medication possession ratio (MPR), integrating prescribed with dispensed medication data, was developed. This measure, MPRp, was compared with a standard dispensed-only adherence measure, MPRd. Adherence below 20% was considered nonadherence. The 2 adherence measures were compared regarding (1) the number of patients identified as nonadherent, (2) percent changes in LDL from study enrollment to study termination, and (3) receiver-operator curves assessing the association between adherence and a 24% decrease in LDL. RESULTS A total of 67,517 patients received 1,386,270 written prescriptions over the 3-year period. MPRp identified 93% more patients as nonadherent than did MPRd (P <.001). These newly identified patients exhibited minimal LDL decreases over the course of the study. Adherence by MPRp was more strongly associated with decreases in LDL than was adherence by MPRd (area under the curve 0.815 vs 0.770; P <.001). During the study period, 18.2% of patients did not fill any prescriptions and were thus unidentifiable by dispensed-only measures. CONCLUSIONS Addition of written-prescription data to adherence measures identified nearly twice the number of nonadherent patients and markedly improved prediction of changes in LDL.

Abstract
BACKGROUND Sepsis results in significant morbidity and mortality, with current treatment options limited with respect to efficacy as well as safety. The complex homeopathic remedy Traumeel S has been shown to have both anti-inflammatory and immunostimulatory effects in the in vitro setting. OBJECTIVES The objective was to explore the effects of Traumeel S in an in vivo setting, using a cecal ligation and puncture (CLP) sepsis model in rats, evaluating the effects of the medication on cytokine activity. DESIGN Sepsis was induced in 30 rats using accepted CLP methodology. Following the procedure, rats were randomly allocated to receive an intraperitoneal injection of either Traumeel S (n=15) or normal saline (n=15). At 6 hours post-CLP, serum cytokines (interleukin [IL]-1β, tumor necrosis factor-α, IL-6, and IL-10) were evaluated. RESULTS IL-1β levels were significantly higher in the treatment group (p=0.03) with no significant differences found between the groups with respect to the other cytokines tested. CONCLUSIONS In contrast to in vitro studies, Traumeel significantly increased IL-1β levels in an in vivo model, without influencing other cytokines. IL-1β is a proinflammatory cytokine that has been shown to have a protective effect in the CLP rat model. Further research is warranted to examine this finding, as well as its clinical implications.

Abstract
BACKGROUND A recent report showed increased frequency of apparent life-threatening events (ALTEs) in infants treated with the homeopathic medication GaliCol-Baby (GCB). The premise was that the ALTEs resulted from toxic effects of the drug's components. We examine an alternative explanation. METHOD The toxicological literature was searched for known reactions to the various GCB components, noting doses and reported symptoms. Dosage quantities and severity of reaction to the GCB were ranked independently by two groups of physicians, and a dose-response curve was generated. Reported toxic doses and symptoms were compared with those of the GCB series. The homeopathic literature was searched as well to determine the propensity of the GCB components to cause ALTE symptoms, when given in homeopathic doses to healthy volunteers (proving). RESULTS Doses ingested in the GCB series were 10-13 orders of magnitude smaller than those reported to cause toxic reactions in humans. There was poor correlation between symptoms with GCB and toxic profiles of the components. A nonsignificant, inverse relationship between dose and severity of reaction was observed. Conversely, four GCB components (in homeopathic doses) had a high propensity to produce at least one of five symptoms which define ALTE, two of which had intermediate to high propensity to produce three symptoms. CONCLUSIONS It is unlikely that the ALTE following ingestion of GCB was a toxic reaction to any of the drug's component. Homeopathic theory may explain this linkage, though further research is needed to understand the pathogenic effects of highly diluted homeopathic compounds.

Abstract
Prurigo Nodularis (PN) is a chronic pruritic skin condition for which current conventional therapies are of limited benefit and with potentially toxic effects. Acupuncture--the insertion of thin needles at specific points on the skin--has been shown to alleviate itching through a number of itch-associated mediator effects. Hypnosis has been shown to modify and reduce the intensity of itching as well. A 44 year-old woman presented with a 30-year history of a diffuse itchy rash diagnosed as PN. She had tried various antihistamine and corticosteroid medications, to no avail. A treatment regimen using hypnosis and acupuncture (hypnopuncture) was initiated, with significant reduction in the itching, size and number of skin lesions. Hypnopuncture may offer a synergistic and augmented response to treatment, though further research is needed to understand the true benefits of this combined regimen.

Abstract
Homeopathy is an empirical method of treatment. Hormesis, while stemming from within the rationalist tradition, has yet to be explained according to current pharmacological theory. Both share in common sub-threshold doses of toxic substances and an initial semi-toxicological insult followed by a greater compensatory (or healing) response. We question whether the differences between these fields may be amenable to scientific research. We identify five cardinal differences between homeopathy and hormesis: (1) Hormesis is a universal phenomenon, while homeopathy is highly specific; (2) Hormesis uses only measurable quantities of compounds, as opposed to homeopathy, which frequently administers medicines at dilutions far beyond the material range; (3) Preparation of hormetic solutions follows standard laboratory procedure, while homeopathy requires a sequential series of dilutions, each followed by vigorous shaking ('succussion'); (4) The effects of hormesis are moderate and temporary, while homeopathy claims curative and permanent responses and (5) Hormesis is a lab phenomenon observed primarily in healthy organisms, whereas homeopathy is a mode of treatment administered primarily to ailing individuals. We believe that all five of these differences are amenable to scientific investigation, and suggest comparing succussed to non-succussed diluted solutions as an optimal first evaluation. We conclude that while certain differences exist between hormesis and homeopathy, hormesis may in fact be a subset of homeopathy.

Abstract
The temporal and spatial patterns of floral determination in cultured internode segments of Nicotiana tabacum L. cv. Wisconsin 38 were investigated. Segments from internodes, when cultured on hormone-free medium, either produced some de novo floral shoots or produced only vegetative shoots. Segments that produced some floral shoots were considered to contain florally determined tissues. The first internode tissues to exhibit floral determination were located 24 nodes (about 15 cm) below the terminal meristem on plants that had 21 leaves of length >/=3 cm (i.e., plants of age 21). Since the terminal meristem was morphologically vegetative at this age, floral determination in internode tissues did not result from a signal emanating from floral structures. As the plant continued growing, internode tissues progressively higher on the main axis gained the capacity to produce de novo floral shoots in culture. These data indicate that the inductive signal which elicited the state of floral determination in internode tissues was active in the upper half of the plant beginning at about age 21.

Abstract
BACKGROUND Symptom checklists used in clinical research of gastroparesis have not been evaluated for reliability or validity. The Gastroparesis Cardinal Symptom Index (GCSI) is a reliable, validated measure whereby patients score three groups of symptoms: nausea/vomiting, postprandial fullness/early satiety and bloating. AIM The purpose of this study was to translate the GCSI into Hebrew and then validate the language of the translation for use in future studies. METHODOLOGY The measure was first translated into Hebrew and then back-translated to English, followed by a comparison of the two versions. The English and Hebrew versions were then completed by 40 healthy bilingual volunteers, using a cross-over design, with half answering the English version first while the other half replied to the Hebrew version first. RESULTS The internal consistency for both measures was moderate, the English slightly lower than the Hebrew (Cronbach's alpha 0.67 vs. 0.72). Intra-class correlation values were larger than 0.7 for all but one of the symptoms (item 3, "vomiting"), although a Wilcoxian signed-rank test found this correlation to be of borderline significance (z=-1.63, p=0.50). CONCLUSIONS The Hebrew translation of the GCSI is valid for use in clinical research, although further psychometric testing is needed to test its value for this purpose. This manuscript describes the stages of measurement, translation and language validation, the difficulties that researches face and possible solutions when researches choose to use a measure which was developed in a different language.

Abstract
The use of complementary and alternative medicine (CAM) is on the rise, especially among psychiatric patients. Acupuncture is considered a safe and effective treatment modality, and traditional Chinese medicine teaches that acupuncture harmonizes the body's energies. Scientific research has found that acupuncture increases a number of central nervous system hormones (ACTH, beta-endorphins, serotonin, and noradrenaline) and urinary levels of MHPG-sulfate, an adrenergic metabolite inversely related to the severity of illness in schizophrenics. Acupuncture can have positive effects on depression and anxiety, although evidence is still lacking as to its true efficacy for these conditions. To the authors' knowledge, no trials have been conducted for schizophrenia, and researchers evaluating acupuncture in cases of substance abuse have found conflicting results. Further research is warranted.

Abstract
The use of complementary and alternative medicine is on the rise, including among patients with epilepsy. Herbal medicine, one of the most popular forms of CAM, is considered to be both safe and effective by most consumers. Yet many herbs may increase the risk for seizures, through intrinsic proconvulsant properties or contamination by heavy metals, as well as via effects on the cytochrome P450 enzymes and P-glycoproteins, altering antiepileptic drug (AED) disposition. Herb-drug interactions may be difficult to predict, especially since the quality and quantity of active ingredients are often unknown. Since most patients do not inform their physicians that they are taking herbal medicines, health care professionals must initiate a dialogue in order to prevent complications with the combined regimen. At the same time, further research is required regarding the effect of herbs on seizure activity and interactions with AED treatment.

Abstract
OBJECTIVE To compare the re-exposure rates of dental radiographs taken over a period of 1 year between dental students and trained dental assistants at a university-based oral and maxillofacial radiology clinic. METHODS Detailed records of the number and type of intraoral radiographs taken by the students and staff members and the number of re-exposures that were required from July 2003 to July 2004 were used. Statistical analyses were performed on the data. RESULTS A chi2 test showed that re-exposure rates of radiographic series between students and staff were statistically different. When comparing the students' re-exposure rates during each of the four quarters of their radiology rotation, one-way analysis of variance test showed that the results were not statistically significant for reduction in the number of re-exposures over the entire year. CONCLUSIONS There were significant differences in the re-exposure rates between staff dental assistants and students. Film re-exposure rates for the students during the four quarters were expected to decrease with time. Instead, the consistency of the re-exposure rates of the students during the four quarters demonstrates the need to recognize why the students did not perform better as the year progressed. The percentage of films that needed to be re-exposed by either group (students or the staff dental assistants) was not extremely high.

Abstract
BACKGROUND Use of homeopathy is not frequently reported in critically ill patients. We describe our experience treating such patients homeopathically in the emergency room, on the wards, and in the intensive care unit of conventional hospitals in Austria and Israel. METHODS We describe a case series of patients treated in the ER for multiple casualty incidents, two case reports of remarkable cures in the ICU, and two RCTs demonstrating the efficacy of homeopathy in septic and intubated patients. RESULTS A case series documents favorable results in homeopathic treatment of patients in the ER and wards after multiple casualty incidents. Two case reports narration e remarkable homeopathic cures to imminently terminal illnesses. Finally, homeopathy was demonstrated effective as compared with placebo in improving long-term survival in severely ill septic patients and in hastening extubation ICU patients. CONCLUSIONS Our report suggests that homeopathy may be applicable even for critically ill patients. We discuss the obstacles encountered, including a dearth of tools for successful homeopathic prescription in these situations, suspicion and lack of cooperation by patients and conventional colleagues, and the highly suppressive nature of concomitant conventional therapies. We suggest the development of algorithms and other tools to aid rapid homeopathic prescription in critical care patients and discuss the importance of familiarizing physicians and medical students with homeopathy in order to facilitate communication and cooperation between these complementary branches of medicine.

Abstract
Homeopathy differs from conventional medicine in many aspects. Little recognized to date is the unique, multidimensional nature of the response to homeopathic treatment. We discuss this 'colour' of the homeopathic response; altered temporal awareness, paucity of language, selective amnesia, lack of self-awareness, the holistic character of the improvement, and the development of acute illnesses, all in response to successful homeopathic treatment. We conclude that, beyond its biological effect, homeopathic treatment affects the awareness.

Abstract
OBJECTIVE To evaluate the effect of Arnica Montana and Bellis perennis on postpartum blood loss. DESIGN Double blind, placebo-controlled, randomized, clinical trial. SETTING Department of Gynecology, Shaare Zedek Medical Center, Jerusalem. INTERVENTIONS Forty parturients were randomized to one of three groups: Arnica montana C6 and Bellis perennis C6 (n=14), Arnica montana C30 and Bellis perennis C30 (n=14), or double placebo (n=12). After 48 h the Arnica/placebo was halted, and patients continued the Bellis/placebo until cessation of lochia. MAIN OUTCOME MEASURES Hemoglobin levels (Hb) at 48 and 72 h postpartum. RESULTS At 72 h postpartum, mean Hb levels remained similar after treatment with homeopathic remedies (12.7 versus 12.4) as compared to a significant decrease in Hb levels in the placebo group (12.7 versus 11.6; p<0.05), in spite of less favorable initial characteristics of the treatment group. The mean difference in Hb levels at 72 h postpartum was -0.29 (95% CI -1.09; 0.52) in the treatment group and -1.18 (95% CI -1.82; -0.54) in the placebo group (p<0.05). CONCLUSION Treatment with homeopathic Arnica montana and Bellis perennis may reduce postpartum blood loss, as compared with placebo.

Abstract
The fibro-osseous lesions represent a large group of disorders that have many common characteristics including clinical, radiographic and microscopic features. Although most are of unknown aetiology, some are believed to be neoplastic and others are related to metabolic imbalances. It is not unusual to see these lesions presenting with a range of radiographic appearances, causing considerable diagnostic confusion owing to their similar histology. This case report presents a histologically benign cemento-osseous lesion that is radiographically consistent with a focal cemento-osseous dysplasia, along with a concomitant simple (traumatic) bone cyst within the right mandibular alveolus, with the initial presentation as a multilocular radiolucency. Pertinent literature is reviewed.

Abstract
A case of dens evaginatus (DE) and dens invaginatus (DI) concurrently affecting the maxillary right permanent lateral incisor in a 25-year-old Hispanic male is reported. DE, referred to as Talon's cusp in the anterior teeth and Leong's premolar in the premolar teeth, is a relatively rare condition by itself. An association of DI with this rare anomaly within the same tooth has never been reported before although it has been known to occur within the same patient. Since it is known that DE may be composed of normal enamel and dentine, as well as varying amounts of pulpal tissue, care should be exercised while performing any aesthetic procedures to remove or recontour it.

Abstract
BACKGROUND Dens Invaginatus (DI), commonly known as dens in dente, is a developmental malformation of tooth that most commonly affects permanent maxillary lateral incisor teeth. Deciduous teeth are infrequently affected. Presence of DI in mandibular permanent teeth is extremely rare. Further, the presence of DI bilaterally in the maxillary lateral incisors of the same patient is even more unusual. METHODS In this article, an unusual case of DI affecting a mandibular lateral incisor tooth is described. This malformation was uncovered after a full mouth radiographic examination when the patient presented for dental treatment unrelated to this finding. In addition, the various radiographic appearances of DI as they present within the maxillary and mandibular teeth are described. Essential clinical considerations and treatment options are presented. A review of the pertinent literature is undertaken and a table summarizing previous published findings of mandibular DI is presented. RESULTS A review of the literature indicates that DI in mandibular teeth is extremely rare with only 10 other cases involving 13 teeth reported previously. CONCLUSIONS Although this is an extremely rare case, DI is an anomaly that should be familiar to all practising dentists due to the clinical implications of potential sequelae of pulpal involvement.

Abstract
The Organon of Medicine is the seminal text of Homeopathy. However, its grammar and structure make it obtuse and remote to both new students and veterans. We propose a demarcation of the Organon into sections, exposing the didactic structure of the Organon, and display this demarcation in concise graphic form. It is hoped that this representation will improve accessibility and understanding of the Organon for readers at all levels.

Abstract
Grafting experiments were used to investigate the relative roles of strength of flowering signal(s) and competence of buds to respond to flowering signal(s) in the development of photoperiodic and day-neutral species of Nicotiana. At the time of commitment to floral development, a flowering signal (inhibitory or promotive) could reach a critical level or terminal buds could gain competence to perceive and-or respond to an existing signal. The latter hypothesis appears to be true for day-neutral N. tabacum L. cv. Wisconsin 38, while signal strength appears to be a more critical factor for long-day N. silvestris L. Nicotiana tabacum and N. silvestris differ in terms of signal intensity at anthesis of the terminal flower. Stocks of N. silvestris promote more rapid flowering in seedling scions of both genotypes. Terminal buds of seedlings of both genotypes have the same competence to respond to the signal affecting floral development. The competence of the terminal bud of both species to respond to this signal(s) changes as a function of age.

Abstract
Floral initiation can be analyzed from a developmental perspective by focusing upon how developmental fates are imprinted, remembered, and expressed. This is not an altogether new perspective, since people studying flowering have been concerned for a long time with the commitment of meristems to form flowers and the morphological, cellular, and molecular changes associated with this commitment. What is novel is the emphasis on developmental states as opposed to physiological processes. This developmental focus indicates that there appear to be at least three major developmental states that are acquired and expressed in the process of a meristem initiating floral morphogenesis. The meristem cells must first become competent to respond to a developmental signal that evokes them into a florally determined state. The leaves are the usual source of this signal and a specific leaf may or may not have the capacity to be inductively active. When a leaf does develop the capacity for inductive activity, this capacity is usually correlated with the ontogeny of the leaf. Inductive activity, however, may be continually expressed as in some day-neutral plants or may be latent as in plants where the photoperiod is the external cue for activity. Competent shoot apical meristems respond to inductive leaf signal by being evoked into a florally determined state. Under permissive conditions this florally determined state is expressed as the initiation of floral morphogenesis. Many mechanisms have evolved to regulate entry into and expression of these developmental states. As we learn more about the developmental states associated with flowering and how they are acquired and expressed, we will understand better how the various patterns of flowering are related to one another as well as which developmental processes are common to all angiosperms.

Determination for inflorescence development is a stable state, separable from determination for flower development in Pisum sativum L. buds. PLANTA 1991; 185:518-522.

Abstract
Terminal meristems of Pisum sativum (garden pea) transit from vegetative to inflorescence development, and begin producing floral axillary meristems. Determination for inflorescence development was assessed by culturing excised buds and meristems. The first node of floral initiation (NFI) for bud expiants developing in culture and for adventitious shoots forming on cultured meristems was compared with the NFI of intact control buds. When terminal buds having eight leaf primordia were excised from plants of different ages (i.e., number of unfolded leaves) and cultured on 6-benzylaminopurine and kinetin-supplemented medium, the NFI was a function of the age of the source plant. By age 3, all terminal buds were determined for inflorescence development. Determination occurred at least eight nodes before the first axillary flower was initiated. Thus, the axillary meristems contributing to the inflorescence had not formed at the time the bud was explanted. Similar results were obtained for cultured axillary buds. In addition, meristems excised without leaf primordia from axillary buds three nodes above the cotyledons of age-3 plants gave rise to adventitious buds with an NFI of 8.3 ±0.3 nodes. In contrast seed-derived plants had an NFI of 16.5 ±0.2. Thus cells within the meristem were determined for inflorescence development. These findings indicate that determination for inflorescence development in P. sativum is a stable developmental state, separable from determination for flower development, and occurring prior to initiation of the inflorescence at the level of meristems.

Abstract
From nonmutagenized haploid suspensions of Nicotiana tabacum L. cv Wisconsin 38 cells, 51 cell lines capable of growth in the presence of 1 millimolar glyphosate (N-phosphonomethyl glycine) were initially isolated at a frequency of 2.3 x 10(-8). Eighteen cell lines retained tolerance when grown on selective medium for 3 years. Tolerance persisted for at least 14 months in six cell lines cultured in the absence of glyphosate. Some plants regenerated from four glyphosate-tolerant cell lines were tolerant. Glyphosate-tolerant tissue was isolated from some sensitive as well as some tolerant regenerated plants. Six of the tolerant cell lines were also tolerant to the herbicide amitrole (3-amino-1,2,4-triazole). Five cell lines selected for amitrole tolerance were glyphosate tolerant. Some plants regenerated from three of these five cell lines were glyphosate tolerant and glyphosate-tolerant tissue was obtained from several of these regenerated plants. Amitrole uptake in suspension cultures of several variants was assessed in terms of influx rate constants. This parameter was not sufficiently different indicating that altered membrane properties could not account for the herbicide tolerance.

When clones were cultured in the absence of amitrole, tolerance persisted for 9 months in five clones. Some plants regenerated from three amitrole-tolerant clones were tolerant. Seven amitrole-tolerant clones were isolated from diploid N. tabacum cell suspensions and R plant tolerance was followed through two sexual generations. Simple Mendelian inheritance patterns were not observed.

Abstract
Transport of the herbicide amitrole (3-amino-1,2,4-triazole) by suspension cultured cells and leaf protoplasts of Nicotiana tabacum cv. Wisconsin 38 has been investigated. Cells were batch-cultured and routinely assayed 3 days after subculturing. Uptake rate was pH-independent, energy independent, and culture growth phase-dependent, with growing cells exhibiting the highest rates. At a concentration of 0.2 millimolar amitrole, uptake rates yielded a Q(10) of 1.6 in the 18 to 28 degrees C temperature range. Amitrole was not concentrated over a 48-hour period and showed unsaturable kinetics over the concentration range of 0.01 to 50.0 millimolar. Uptake was not significantly influenced by a 100-fold higher concentration of several amino acids (l-Asp, gamma-amino-n-butyric acid, l-His, l-Leu, l-Met, l-Trp), sucrose, glucose, fructose, and oxaloacetic acid. Uptake rate inhibition by malic acid and stimulation by NH(4)SCN were statistically significant. Amitrole was bound to cellular material, but uptake of amitrole by tobacco leaf protoplasts demonstrated that cell walls did not qualitatively influence uptake. These results indicate that amitrole enters the cells via simple diffusion.
