Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) elicits an interferon (IFN) deficiency state, which aggravates the type I interferon deficiency and slow IFN responses, which associate with e.g. aging and obesity. Additionally, SARS-CoV-2 may also elicit a cytokine storm, which accounts for disease progression and ultimately the urgent need of ventilator support. Based upon several reports, it has been argued that early treatment with IFN-alpha2 or IFN-beta, preferentially in the early disease stage, may prohibit disease progression. Similarly, preliminary studies have shown that JAK1/2 inhibitor treatment with ruxolitinib or baricitinib may decrease mortality by dampening the deadly cytokine storm, which - in addition to the virus itself - also contributes to multi-organ thrombosis and multi-organ failure. Herein, we describe the rationale for treatment with IFNs (alpha2 or beta) and ruxolitinib emphasizing the urgent need to explore these agents in the treatment of SARS-CoV-2 - both as monotherapies and in combination. In this context, we take advantage of several safety and efficacy studies in patients with the chronic myeloproliferative blood cancers (essential thrombocythemia, polycythemia vera and myelofibrosis) (MPNs), in whom IFN-alpha2 and ruxolitinib have been used successfully for the last 10 (ruxolitinib) to 30 years (IFN) as monotherapies and most recently in combination as well. In the context of these agents being highly immunomodulating (IFN boosting immune cells and JAK1/2 inhibitors being highly immunosuppressive and anti-inflammatory), we also discuss if statins and hydroxyurea, both agents possessing anti-inflammatory, antithrombotic and antiviral potentials, might be inexpensive agents to be repurposed in the treatment of SARS-CoV-2.

Abstract
The aim of this report is to present a patient with traumatic optic nerve sheath hematoma (ONSH), a rare diagnosis with high potential for visual sequelae. This case involves a 41-year-old male who presented promptly following blunt trauma to the right eye and orbit that resulted in acute vision loss. Following computed tomography and ophthalmic examination, a diagnosis of ONSH was made and medical therapy with methylprednisolone was initiated. He reported significant improvements in visual symptoms following intravenous corticosteroid therapy. Although the patient reported significant improvements and had normal Snellen visual acuities in follow-up, he continued to have an inferior visual field defect at 1 week in the affected eye. ONSH causing subsequent localized compression of the optic nerve is a rare mechanism of traumatic optic neuropathy in patients following head trauma. The localized compartment syndrome of the optic nerve and subjective visual symptoms were relieved following corticosteroid therapy with no initial need for surgical decompression. Although central visual acuity returned to baseline, the patient had a persistent visual field defect and relative afferent pupillary defect.

Abstract
Severely afflicted patients with the COVID-19 may become in need of mechanical ventilation. The cause of acute respiratory failure is a massive hyperinflammation in the lungs, and treatment with glucocorticoids is not recommended by the WHO. A rare haematological disease, the virus-associated haemophagocytic lymphohistiocytosis syndrome (HLS), is associated with high mortality and a similar hyperinflammation syndrome. Janus kinase (JAK) 1/2 inhibitor treatment is highly efficacious in HLS. In this review, we discuss the rationales and perspectives for using JAK1/2 inhibitors in severely afflicted patients with COVID-19 pneumonia.

Abstract
INTRODUCTION The coronavirus disease 2019 (COVID-19)pandemic reached Denmark in early 2020. This paper presents initial intensive-care unit (ICU) experiences with COVID-19 patients at Roskilde Hospital, which was the primary recipient of COVID-19 patients in need of intensive care in the Zealand Region, Denmark. METHODS An evaluation was conducted of the COVID-19 patients admitted to the ICU due to respiratory failure from 11 March 2020 to 01 April 2020. The number of ICU beds was increased from eight to 22 beds during this period. RESULTS Sixteen patients (four women) were evaluated. The median age was 69.5 years (range: 56-84 years). All the patients were admitted to the ICU for hypoxemic respiratory failure and all needed mechanical ventilation by orotracheal intubation. By 16 April, six patients were still admitted to the ICU, four patients had been discharged from the ICU and seven had died. At present, the average length of ICU stay is 14 ± 9 days (mean ± standard deviation). One patient has remained on ventilatory support for 31 days. The evaluation revealed four key themes. COVID-19 patients 1) had greatly increased C-reactive protein levels, 2) needed a significant inspiratory O2fraction, 3) were highly positive end-expiratory pressure (PEEP) dependent on ventilatory support and 4) suffered highly fluctuating respiratory failure requiring ventilatory support for a significantly longer period of time than non-COVID-19 patients. CONCLUSIONS COVID-19 patients have characteristic reproducible laboratory findings and present a major challenge due to their illness severity and required treatment length. FUNDING none. TRIAL REGISTRATION not relevant.

Abstract
Climate induced changes in the Arctic Ocean have severely impacted underwater acoustic communication and navigation; understanding underwater noise characteristics is critical to improving the performance of these operations. Ambient noise from the Beaufort Sea recorded in experiments more than 20 years apart (SIMI94 and ICEX16) are compared to determine differences that may be attributed to the region's rapidly changing environment. Spectral comparison shows noise within 20-350 Hz is ∼30 dB louder in 1994 than 2016; however, this is likely due to higher array self noise during SIMI94. Beamforming results show ambient noise vertical directionality is focused near the horizontal during SIMI94 but more spread in elevation during ICEX16, with a robust noise notch at the horizontal. Numerical modeling demonstrates that this difference may be attributed to ambient noise during ICEX16 being dominated by surface noise sources at discrete ranges rather than the historical assumption of a continuous and uniform distribution of sources. Temporal statistics of transient ice events show more acoustic activity during SIMI94 than ICEX16 and appear to support the new proposed surface source distribution for ICEX16.

Abstract
INTRODUCTION Otitis media is one of the most common diseases in small children. This underlines the importance of optimizing diagnostics and treatment of the condition. Recent literature points toward a stricter approach to diagnosing acute otitis media (AOM). Moreover, ventilating tube treatment for recurrent AOM (RAOM) and chronic otitis media with effusion (COME) has become the most frequently performed surgical procedure in pre-school children. Therefore, the Danish Health and Medicines Authority and the Danish Society of Otorhinolaryngology, Head and Neck Surgery deemed it necessary to update the Danish guidelines regarding the diagnostic criteria for acute otitis media and surgical treatment of RAOM and COME. METHODS The GRADE system (The Grading of Recommendations Assessment, Development and Evaluation) was used in order to comply with current standards of evidence assessment in formulation of recommendations. An extensive literature search was conducted between July and December 2014. The quality of the existing literature was assessed using AGREE II (Appraisal of Guidelines for Research & Evaluation), AMSTAR (assessing the Methodological Quality of Systematic Reviews), QUADAS-2 (Quality of Diagnostic Accuracy Studies), Cochrane Risk of Bias Tool for randomized trials and ACROBAT-NRSI (A Cochrane Risk of Bias Assessment Tool for Non-Randomized Studies). The working group consisted of otolaryngologists, general practitioners, pediatricians, microbiologists and epidemiologists. CONCLUSION Recommendations for AOM diagnosis, surgical management for RAOM and COME, including the role of adenoidectomy and treatment of ventilating tube otorrhea, are proposed in the guideline.

Abstract
Introduction: With cardiovascular disease (CVD) increasing for female workers, there is a need to understand the factors associated with CVD in members of the occupational therapy, predominantly female, profession. The association between burnout and physical health effects, such as CVD, has not been investigated in paediatric occupational therapists. Method: Associations between CVD and demographic and work-life factors were investigated in a nationwide postal survey of 486 paediatric occupational therapists. Results: The prevalence of CVD in the study population was 11.02%. Private practitioners, older therapists and those with additional self-reported health problems from respiratory disease had increased odds of reporting CVD. In contrast, lower odds of CVD were found for therapists with access to social support, a secure attachment style and income satisfaction. Conclusion: Understanding demographic, personal and work-related variables associated with CVD in paediatric occupational therapists provides valuable information about members of the profession. The identification of potentially modifiable work-life factors that are inversely associated with CVD, such as social support and having a secure attachment style, suggests further avenues for research and intervention. Ongoing vigilance, and education directed towards self-care as well as client care, is required to ensure optimal health for colleagues.

Abstract
Introduction: An attachment framework has been increasingly employed to inform our understanding of the ways in which early childhood relationships have an impact upon people's adaptation to the workplace. Evidence supports the presence of four attachment-related work orientations in adulthood (secure, cautious, support-seeking and self-reliant), which correspond to a secure and three insecure attachment patterns in early childhood. Although these work orientations have been investigated in several working populations, they have not yet been considered within a sample of occupational therapists. Method: The present exploratory study considered the results of a nationwide survey of 486 paediatric occupational therapists, and investigated the associations between attachment styles and a range of demographic variables and work-related self-perceptions. Results: Consistent with hypotheses, those with a secure attachment style reported a high investment of skill and energy in their job and low levels of over commitment. Conversely, cautious attachment and, to a lesser extent, support-seeking attachment were linked with feeling overcommitted and perceiving low returns in terms of recognition and prestige from their work. Conclusion: Understanding how practitioners' predominant attachment style is associated with work-related self-perceptions may offer insights into their behaviours and needs. This, in turn, can inform the provision of appropriate supports, with potential benefits for staff satisfaction, retention, health, wellbeing and, ultimately, client care.

Abstract
Epidemiologic data regarding the chemopreventive potential of nonsteroidal anti-inflammatory drugs (NSAIDs) against oral cancer are sparse. We found a relative risk for oral cancer of 1.2 (95% CI, 1.0–1.6) among 169 589 Danish NSAID users (≥2 prescriptions), with no apparent trends in subgroups. Our study provided no clear evidence that NSAIDs may protect against oral cancer.

Abstract
The aim of this randomized study was to compare the longevity and cariostatic effects of 1565 class II restorations in primary teeth placed by 15 clinicians in the Danish Public Dental Health Service in 971 children, aged 3.6-14.9 yr. The restorations were performed using three resin-modified glass ionomer cements and one compomer (polyacid-modified composite resin) with and without their respective cavity conditioners. The restorations were in contact with 1023 unrestored proximal surfaces in 853 primary and 170 permanent teeth. The study was terminated after 7 yr with 1% of the restorations in function, 7% patient dropouts, 18% failed restorations, and operative treatment on 24% of the adjacent surfaces. Multivariate survival analyses showed that the restorative material and cavity conditioning influenced the survival of restorations but not the progression of caries on adjacent surfaces. The 50% survival times were estimated to exceed 5 yr for the restorations and 4.5 yr for the adjacent unfilled surfaces in all treatment groups. It was concluded that resin-modified glass ionomer cement and compomer are both appropriate materials for class II restorations in primary teeth. The differences in longevity and cariostatic effects among the four materials used with and without conditioner were less than the intra-individual differences between clinicians.

Abstract
BACKGROUND Monitoring with pulse oximetry might improve patient outcome by enabling an early diagnosis and consequently, correction of perioperative events that might cause postoperative complications or even death. Only a few randomised clinical trials of pulse oximetry have been performed during anaesthesia and in the recovery room which describe perioperative hypoxaemic events, postoperative cardiopulmonary complications and cognitive dysfunction. OBJECTIVES To study the effect of perioperative monitoring with pulse oximetry to clearly identify the adverse outcomes that might be prevented or improved by the use of pulse oximetry. SEARCH STRATEGY Trials were identified by computerised searches of the Cochrane Library, MEDLINE, EMBASE, and by checking the reference lists of trials and review articles. SELECTION CRITERIA All controlled trials that randomised patients to either pulse oximetry or no pulse oximetry during the perioperative period, including the operating and recovery room. DATA COLLECTION AND ANALYSIS We collected data in relation to events detectable by pulse oximetry, any serious complications that occurred during anaesthesia or in the postoperative period, intra- or postoperative mortality, and duration of recovery or intensive care stay. Formal statistical synthesis of individual trials was not performed in view of the variety of outcomes studied. MAIN RESULTS Searching identified six reports; four studies with data from a total of 21,773 patients were considered eligible for analysis. Only two studies specifically addressed the outcomes in question; both found no effect on the rate of postoperative complications using perioperative pulse oximetry. Two studies used hypoxaemia detectable by pulse oximetry to assess the value of perioperative monitoring, although outcomes were not given. It was found that hypoxaemia was reduced in the pulse oximetry group both in the operating theratre and in the recovery room. During observation in the recovery room, the incidence of hypoxaemia in the pulse oximetry group was 1.5-3 times less. The postoperative cognitive function using the Wechsler memory scale and continuous reaction time was independent of perioperative monitoring with pulse oximetry. The other study showed that postoperative complications occurred in 10% of the patients in the oximetry group and in 9.4% in the control group. The two groups did not differ in cardiovascular, respiratory, neurologic, or infectious complications. The duration of hospital stay was a median of 5 days in both groups, and an equal number of in-hospital deaths was registered in the two groups. REVIEWERS' CONCLUSIONS The studies confirmed that pulse oximetry can detect hypoxaemia and related events. However, we have found no evidence that pulse oximetry affects the outcome of anaesthesia. The conflicting subjective and objective results of the studies, despite an intense, methodical collection of data from a relatively large population, indicate that the value of perioperative monitoring with pulse oximetry is questionable in relation to improved reliable outcomes, effectiveness and efficiency.

Abstract
Heteroduplex mobility assay was used to identify variants of varicella-zoster virus (VZV) circulating in the United Kingdom and elsewhere. Forty variable positions were identified. Sixteen substitutions were non-synonymous, resulting in an amino acid change, the majority of which were clustered within surface expressed proteins. Phylogenetic analysis distinguished at least three major clades (strains A, B, C) supported by significant bootstrap values. Apart from the United Kingdom and Brazil where all three strains were found, genotypes appeared to be closely associated with the geographical region in which they were sampled. Allelic co-segregation of widely spaced single nucleotide polymorphisms (SNPs) confirmed the genetic stability of the VZV. Recombination rates were difficult to calculate because of the low intra genotypic variation. However, one haplotype originating from Brazil is most parsimoniously explained as a recombinant between A and C strains, which co-occur in the region. Two further UK strains appeared to be recombinants between groups B and C.

Abstract
Dengue hemorrhagic fever (DHF) is caused by dengue virus. Patients with DHF grade 3-4, termed Dengue Shock Syndrome (DSS), may develop acute respiratory failure after initial fluid resuscitation. Previously, these patients were treated with oxygen on a nasal cannula, or if necessary with tracheal intubation and mechanical ventilation. In the present prospective randomized study, we compared the effectiveness of oxygen treatment administered by a face mask vs. nasal continuous positive airway pressure (NCPAP). Morbidity, mortality, and supportive treatment was evaluated. Thirty-seven patients with DSS complicated by respiratory failure were enrolled. On admission and after 30 min of treatment, clinical and paraclinical data were obtained. Chest X-ray revealed pleural effusion in 92 per cent and showed interstitial oedema in 33 per cent. After 30 min of treatment the respiratory rate decreased significantly in the NCPAP group (p < 0.05), while SaO2 and PaO2 increased in both groups (p < 0.01). However, subsequently a significant difference of unresponsiveness to treatment between the oxygen mask group and the NCPAP group (13/19 vs. 4/18,p < 0.01) was noted. Complications of NCPAP or oxygen mask treatment were not documented. We conclude that NCPAP is useful in improving the management of acute respiratory failure in children with DHF/DSS in dengue-endemic areas.

Abstract
OBJECTIVE To determinate the relative importance of state of nutrition and intensity of exposure for clinical severity of chickenpox in a developing country. METHODS A prospective household study was performed in a semi-urban area in Bissau, the capital of Guinea-Bissau, between December 1994 and June 1995. Antibodies were measured in the acute and the convalescence phase to assess validity of clinical diagnoses. The clinical severity of infection was assessed by number of pox, fever response and skin infections. Severity was compared for index cases, i.e. the first case in the house, and secondary and tertiary cases infected following exposure at home. RESULT Chickenpox was diagnosed in 165 persons. The clinician's and the mothers' diagnoses corresponded well with the serological results. Median age was 36 months (range 3 months to 30.3 years). There was no correlation between nutritional status measured by arm-circumference and severity of infection. The number of pox was higher for secondary cases than for index cases (median 106 vs. 89, P<0.01), the difference being more pronounced for girls (P=0.018) than for boys (P=0.575). The risk of skin infection as a complication was correlated with the number of pox (P<0.001). CONCLUSION Chickenpox was recognised correctly by Guinean mothers. The age distribution in Guinea-Bissau resembled the pattern in developed countries. The intensity of exposure was a major determinant of severity, especially for girls.

Abstract
We present a prospective case-control study of 27 serologically confirmed dengue hemorrhagic fever (DHF) patients with severe central nervous system symptoms. Dengue associated encephalopathy accounted for 0.5% of 5,400 patients admitted with DHF. The mortality rate among children with encephalopathy was 22%, with the survivors experiencing a complete recovery. Liver enzymes and bilirubin were significantly elevated in the study group. In analysis of the cerebrospinal fluid (CSF), reverse transcriptase-polymerase chain reaction revealed dengue-3-specific RNA in one evaluated case. Dengue-specific immunoglobulin M was detected in CSF in 14 of 22 assessable patients, indicating a localized infection. Magnetic resonance imaging scans showed cerebral edema in the majority of patients, although encephalitis-like changes were less common. There was an equal distribution of primary and secondary infections. On the basis of previous reports and of the findings of our study, DHF probably encompasses an expanding clinical spectrum that infrequently involves encephalitis due to a direct neurotropic effect of dengue virus.

Abstract
BACKGROUND Pneumocystis carinii pneumonia (PCP) is a wellknown risk among patients with deficient T-cell function such as children treated for acute lymphoblastic leukemia (ALL). The purpose of this study was to estimate the risk for PCP during maintenance treatment (MT) to identify patients at risk who could benefit from prophylaxis. PROCEDURE We registered all episodes of PCP during MT in 71 children diagnosed between January 1992 and June 1997 with non-B-cell ALL at The Copenhagen University Hospital. Sulphametoxazole and trimetroprim (SMX/TMP) prophylaxis against PCP was given during induction and consolidation therapy but stopped prior to MT with oral methotrexate/6-mercaptopurine. Patients with standard (SR), intermediate (IR), and high risk (HR) ALL started MT at 3, 8, and 15 months from diagnosis, respectively. RESULTS The HR group had a cumulated risk of 70% for developing PCP, whereas the risk for PCP in children with IR and the SR was 11 and 8%, respectively (P < 0.0001). All but one of these 13 cases of PCP occurred within 8 months after cessation of SMX-TMP prophylaxis. CONCLUSIONS The higher incidence of PCP among HR compared to non-HR patients following cessation of SMX/TMP prophylaxis probably reflects the significantly longer T-cell suppressive consolidation therapy in this group. The very low incidence of PCP during the later part of MT emphasizes that methotrexate/6-mercaptopurine MT have more impact on B-cell than on T-cell function. TMP/SMX prophylaxis should be recommended for all children treated for ALL.

Abstract
Dengue virus is transmitted by mosquitoes and causes dengue fever/dengue haemorrhagic fever throughout the tropical areas of the world. There is an increasing incidence of dengue infections. Because of increasing travel activity, infection among Danes travelling abroad as well as imported cases are expected to be seen more frequently. In this review we describe the clinical manifestations, diagnosis, pathogenesis, treatment and prevention of the disease.

Abstract
Complications in two varicella zoster virus (VZV) vaccinated children with leukemia in remission are reported. Case I presented with varicella on day 30 after vaccination, with a relapse on day 49 and development of zoster on day 70. VZV was detected in vesicles by PCR on days 49 and 70. Case II presented with varicella on day 32 after vaccination, and VZV was detected in vesicles and nasal secretion. The manifestations were mild and responded to treatment. PCR methods were directed toward the R5 and PS regions. The virus from the two children was unambiguously identified as the Oka vaccine strain. The majority of Danish field strains had only one copy of the 112 basepair repeat element in the R5 region, but two, four and presumably higher copy numbers were also seen. All Danish field strains had the Pst1 cleavage site in the PS region.

Abstract
The aim of this study was to compare the longevity and cariostatic effects of everyday conventional glass-ionomer and amalgam restorations in primary teeth. The materials consisted of 515 Ketac-Fil glass-ionomer restorations and 543 Dispersalloy amalgam restorations prepared in 666 children, from 3 to 13 years of age, by 14 dentists within the Danish Public Dental Health Service in the municipalities of Vaerløse and Hillerød. The restorations, of which 79% were of the Class II type, were in contact with 593 unrestored surfaces in adjacent primary and permanent teeth. After 3 years, 6% of the patients had dropped out of the study, and 33% of the teeth were exfoliated with the restoration in situ. A further 37% of the glass-ionomer and 18% of th amalgam restorations were recorded as failed (p < 0.001). The frequency of failures was highest for Class II glass-ionomer restorations, which showed a 50% median survival time of only 34 1/2 months, because of many fractures, while the 75% survival time for Class II amalgam restorations just exceeded the actual 36 months (p < 0.001). Caries progression was most often recorded in surfaces adjacent to amalgam restorations, and 21% of these surfaces needed restorative treatment vs. 12% of the surfaces adjacent to glass-ionomer restorations (p < 0.001). The three-year results indicated that conventional glass ionomer is not an appropriate alternative to amalgam for all types of restorations in primary teeth. In particular, the short longevity of Class II glass-ionomer restorations could not be compensated for by the reduced caries progression and need for restorative therapy of adjacent surfaces.

Abstract
During the period July 1986 through December 1991, 67 children were treated for non-B-cell acute lymphoblastic leukemia at The Juliane Marie Centre, GGK, The University Hospital Rigshospitalet, Copenhagen. Twenty-five children were susceptible to varicella zoster (VZ) virus at diagnosis. For these patients the cumulated risk of VZ exposure was 90% after 32 months. Five patients developed varicella (two of whom had pneumonitis) during the period of antileukemic treatment. Two of these had received prophylactic treatment with acyclovir. The 2 year cumulated risk of having chickenpox or herpes zoster in children with previous VZ infection was 24% and 34%, respectively. VZ vaccination ought to be considered for this group of children in order to diminish transmission and morbidity.

Abstract
In two trials of measles vaccination in Guinea-Bissau, children were randomized to receive either the Edmonston-Zagreb (EZ) virus at age 4-8 months or, as a control group, a standard dose (5000 p.f.u.) of the Schwarz (SW) virus at 9-12 months. In the first trial a medium dose of EZ virus (40,000 p.f.u.) was used and in the later trial a high dose (150,000 p.f.u.). Pre- and postvaccination blood samples were analysed with a haemagglutination inhibition (HAI) test and an enzyme-linked immunosorbent assay (ELISA). For the ELISA the blood samples were collected on filter paper. Of 362 prevaccination specimens, 18 and 55%, respectively, were positive in the ELISA and HAI tests. At 18-20 months, the children who had received the EZ vaccine had a seropositivity of 91% by the ELISA method and one of 89% by the HAI method. The equivalent values for the SW group of children were 100 and 96% respectively. Antibody levels in the EZ group, as measured by either method, were significantly lower than the levels in the SW group. The serological results of the present study suggest that lowering the age at measles vaccination to below 9 months is feasible. However, further studies are needed to determine which virus strain, dosage and age at vaccination will prove to be optimal in countries where severe measles is common before the age of 9 months.

Abstract
A trial of protective efficacy which compared medium-titre Edmonston-Zagreb (EZ) measles vaccine (10(4.6) p.f.u.) from the age of 4 months with the standard Schwarz (SW) measles vaccine given from the age of 9 months was started in an urban community in Guinea-Bissau in 1985. Because trials of high-titre measles vaccine have found increased mortality among female recipients, we examined whether EZ medium-titre vaccine was associated with any long-term impact on mortality, suppression of T-cells, or growth. The mortality rate ratio over 5 years of follow-up was 1.12 for EZ children compared with children in the standard group (P = 0.63). Seventy-five percent of the children still residing in the area at 5 years of age took part in an immunological and anthropometric examination. There was no difference in T-cell subsets between the two groups. There was no difference in mid-upper-arm circumference, but EZ children were significantly shorter than the children in the standard group. In conclusion, medium-titre EZ was not associated with reduced survival or persistent immunosuppression.

Abstract
In an urban area of Guinea-Bissau, 384 children were enrolled in a randomized trial comparing morbidity and mortality rates after receiving high-titer Edmonston-Zagreb (EZ) measles vaccine administered from 4 months of age, with a control group receiving inactivated poliomyelitis vaccine at 4 months of age and the standard Schwarz vaccine from 9 months of age. Children were followed to the age of at least 3 years. The mortality ratio of the EZ vaccinees compared with control subjects was 1.79 (range, 1.06 to 3.02; p = 0.027) if children were excluded at the time of migration; if deaths after migration were included, the mortality ratio was 1.53 (range, 0.94 to 2.49; p = 0.087). Girls in the EZ group had significantly higher mortality rates than girls in the control group (mortality ratio = 1.95; range, 1.07 to 3.56; p = 0.027); there was no difference for the boys (mortality ratio = 0.98; range, 0.41 to 2.30). Adjustment for background factors in a Cox regression model did not modify these estimates. Furthermore, female recipients of EZ vaccine had more days with diarrhea (relative risk = 1.35; range, 1.17 to 1.56; p = 0.00003) and were more likely than control subjects to visit a health center in the month after vaccination (relative risk = 1.86; range, 1.05 to 3.31; p = 0.027); those who consulted were more likely to die subsequently (mortality ratio = 2.31; range, 0.99 to 5.41; p = 0.054). These observations were unplanned and require confirmation in larger studies.

Abstract
Forty-six female patients with rheumatoid arthritis or primary Sjögren's syndrome participated in a prospective, controlled study of psychodynamic, time-limited group therapy. The paper concentrates on the qualitative outcome evaluated according to the patients' perceptions of what was appreciated as being most helpful in the group. Yalom's 'curative factors Q-sort' served as parameter of effect. Special attention will be given to the prevalence of alexithymia in rheumatic patients, and to the possibilities of ameliorating alexithymic features through group therapy.

Abstract
Measles incidence, vaccine efficacy, and mortality were examined prospectively in two districts in Bissau where vaccine coverage for children aged 12-23 months was 81% (Bandim 1) and 61% (Bandim 2). There was little difference in cumulative measles incidence before 9 months of age (6.1% and 7.6%, respectively). Between 9 months and 2 years of age, however, 6.1% contracted measles in Bandim 1 and 13.7% in Bandim 2. Even adjusting for vaccination status, incidence was significantly higher in Bandim 2 (relative risk 1.6, P = .04). Even though 95% of the children had measles antibodies after vaccination, vaccine efficacy was not more than 68% (95% confidence interval [CI] 39%-84%) and was unrelated to age at vaccination. Unvaccinated children had a mortality hazard ratio of 3.0 compared with vaccinated children (P = .002), indicating a protective efficacy against death of 66% (CI 32%-83%) of measles vaccination. These data suggest that it will be necessary to vaccinate before age 9 months to control measles in hyperendemic urban African areas.

Abstract
When blood samples were analyzed for seroconversion after measles vaccination, it was discovered that the vaccine had been ineffective for a certain period. During the 2 years between vaccination and the time of seroanalysis, nonseroconverters had a significantly higher mortality than seroconverters (P less than 0.05). The incidence of measles among nonseroconverters was 30% during the period. Between 9 months and 3 years of age, cumulative mortality was 15.1% for nonseroconverters and 4.5% for seroconverters. The difference in mortality was larger when high risk groups (twins, motherless children) were excluded from the analysis (P less than 0.01). The difference in mortality was particularly marked among children vaccinated in the age group 9 to 11 months. This as well as other community studies suggest that measles vaccination reduces child mortality from the age of vaccination by at least 30%.

Abstract
In a randomised study of 558 children in an urban African community, the protective effect of the Edmonston-Zagreb (EZ) measles vaccine given in a dose of 40,000 plaque forming units from the age of 4 months was compared with the effects of a standard dose (6000 tissue culture infectious units) of Schwarz measles vaccine given from the age of 9 months. During two years of follow-up, all 14 clinical cases of measles occurred in the Schwarz group; 10 of the children contracted measles before vaccination and 4 after measles vaccination. Thus the EZ vaccine provided significant protection against measles both before and after the usual age of vaccination. Among the children who were exposed to measles at home, those given EZ vaccine were better protected than either unvaccinated children or those given the Schwarz vaccine.

Abstract
The autoinoculation test has been used as a diagnostic procedure in patients with chancroid-suspected genital ulcerations. In four of 13 patients with a positive autoinoculation test, herpes simplex virus type 2 was isolated from the primary lesions. In two of the cases this virus was also isolated from the inoculation site, and one patient developed a recurrent herpetic eruption here. Two patients were proven to have chancroid. Three of the remaining seven patients developed recurrent herpes genitalis later. It is concluded that the autoinoculation test should be avoided as a diagnostic procedure because of lack of specificity and risk of inducing recurrent herpes simplex at the site of inoculation.

Abstract
Correlations between the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) and the Southern California Sensory Integration Tests (SCSIT) were studied by using test results obtained from a sample of 49 learning-disabled children. It was found that those SCSIT tests with a motor component correlated significantly with the BOTMP battery composite scores. The fine motor composite scores of the BOTMP reflected the greatest percentage of significant correlation with SCSIT tests. These results suggested that the BOTMP would be useful for screening children for referral to occupational therapy by educators. In addition, the high correlation of the BOTMP with the SCSIT motor tests indicated that the BOTMP may be appropriate for use in clinical research to evaluate the effectiveness of sensory integrative procedures in relation to motor function.
