Acute lacerations: Assessment and non-surgical management.

BACKGROUND: Given appropriate case selection and capability, many acute lacerations can be managed in the primary care setting. An understanding of the basic pathophysiology, assessment and management principles is essential. OBJECTIVE: The aim of this article is to provide a basic framework for assessing and managing simple acute lacerations. DISCUSSION: The aim of assessment is initially to decide whether the laceration is suitable for office-based treatment, and then whether it requires formal surgical closure with sutures or staples. Two non-surgical techniques for skin closure in amenable wounds are described. A companion article in this issue provides details of surgical closure techniques and wound aftercare.

Tetanus vaccination status and its associated factors among women attending a primary healthcare center in Cairo governorate, Egypt.

BACKGROUND: Maintaining maternal and neonatal tetanus (MNT) elimination status in Egypt requires continued strengthening of routine tetanus toxoid (TT) immunization services for pregnant women. OBJECTIVES: To measure the frequency rate of TT vaccination among women attending the well-baby clinic at the El-Darb El-Ahmar primary healthcare center in Cairo governorate and to identify different associated factors. PARTICIPANTS AND METHODS: This was a cross sectional study that targeted 277 mothers who attended the well-baby clinic at the El-Darb El-Ahmar primary healthcare center. Mothers were interviewed by a questionnaire inquiring about their sociodemographic characteristics, obstetric history, details of the last pregnancy, TT vaccination status and knowledge of the TT vaccine, and MNT disease. RESULTS: The results showed that 60.6% had taken all required doses of TT vaccine and 42.6% of the mothers studied were fully protected against MNT in their last birth. The rate of vaccination was found to be affected by mothers' socioeconomic level, education level, place of receiving antenatal care, health education about importance of TT vaccine, knowledge of mothers about NT disease and TT vaccine and the source of this knowledge.

Epidemiological review of scorpion stings in Qatar. The need for regional management guidelines in emergency departments.

OBJECTIVES: To review the epidemiology of scorpion sting in Qatar, to explore both the clinical significance, and the role of the emergency department (ED) in the management of such cases. METHODS: In this retrospective study, we reviewed the records of all scorpion sting cases presented to the ED of Hamad General Hospital, Doha, Qatar between October 2010 and May 2013. RESULTS: A total of 111 cases of scorpion stings were reviewed, 81 (72.9%) were males and 30 (27.1%) were females, with a mean age of 38 years. Localized pain was the most frequent presenting complaint (89 [80.2%]), whereas localized redness (44 [39.6%]) and swelling (38 [34.2%]) were the most common clinical signs. Abroug's classification was used, and all cases  were found to be class I. All patients received symptomatic treatment and were sent home. CONCLUSION: Scorpion sting problem in Qatar has a low clinical significance. Data from such studies should be utilized to create more specific (local) management guidelines, which should be more efficient with more rational utilization of ED resources.

Effectiveness and cost of quick diagnostic tests to determine tetanus immunity in patients with a wound in French emergency departments.

BACKGROUND: Tétanos Quick Stick® (TQS) is a test for tetanus immunity screening for wounded patients in emergency departments (EDs), but represents additional costs compared with a medical interview on vaccination history. The study objective was to assess the effectiveness and cost of the TQS in French EDs. METHODS: We performed a model-based analysis that simulates screening of tetanus immunity and risk of tetanus based on prophylaxis administration. Strategies compared were: i) diagnosis of tetanus immunity by "TQS"; ii) "Medical Interview" (current practice). The study population was 1,658,000 French adults seeking ED care for a wound in 2012. Model parameters were estimated based on French national surveillance data, and published literature. Outcome measures were number of tetanus cases, life years gained and costs (2012 €) from a societal perspective. RESULTS: Use of TQS had negligible impact on health outcomes (0.02 tetanus cases/year in France vs. 0.41 for "Medical Interview"), but resulted in a decrease in annual costs of €2,203,000 (-42%). Base case and sub-group analysis showed that with the same effectiveness, the average cost per patient was: €13 with "Medical Interview" vs. €11.7 with TQS for the overall cohort; €28.9 with "Medical Interview" vs. €21 with "TQS" for tetanus-prone wounds; €15 with "Medical Interview" vs. €14.1 with "TQS" for patients aged ≥65 years; and €6.2 with "Medical Interview" vs. €7.8 with "TQS" for non-tetanus-prone wounds. CONCLUSIONS: Use of TQS is as effective and less costly than "Medical Interview" when applied in ED to wounded patients with tetanus-prone wounds or aged ≥65 years. However, it is more expensive in patients with non-tetanus-prone wounds.

The impact of community-based, workshop activities in multiple local dialects on the vaccination coverage, sanitary living and the health status of multiethnic populations in Lao PDR.

Studies on effective community-based intervention in areas inhabited by multiple ethnic groups are limited. The present study was performed to evaluate the impact of workshop activities in multiple local dialects guided by lay facilitators on vaccination coverage, sanitary living and health status in a northern district of Lao PDR. In target villages, facilitators were selected and trained to assist at village meetings to discuss health issues and develop and implement action plans. Manuals and posters with graphics were distributed. Skills were taught through demonstrations by specialists. The vaccination coverage among children and women improved significantly after 1 year. Villagers started using toilets, collecting and burning garbage, and isolating animals from human dwellings, and these activities were continued in 76, 84 and 87% of villages, respectively, 5 years after the start of the activities. The frequency of villagers falling ill was reduced in 67% of the villages. After adjustment for sociocultural characteristics and ethnicity, both the continuous sanitary living index and the reduction in the frequency of villagers falling ill were associated with the higher levels of community participation in the workshop activities. The results demonstrated that the community-based workshop activities improved vaccination coverage, sanitary living and health status. Participatory group discussions in local dialects and village activities led by lay facilitators, supervision and consultation by district trainers who were well recognized by villagers, and the distribution of pictorial educational materials can be an effective and sustainable health promotion approaches among multiethnic groups in under-resourced areas.

Effectiveness and cost of immunization recall at school-based health centers.

BACKGROUND AND OBJECTIVE: Effectiveness of recall for immunizations has not been examined in the setting of school-based health centers (SBHCs). We assessed (1) immunization rates achieved with recall among sixth-grade girls (demonstration study); (2) effectiveness of recall among sixth-grade boys (randomized controlled trial [RCT]); and (3) cost of conducting recall in SBHCs. METHODS: During October 2008 through March 2009, in 4 Denver public SBHCs, we conducted (1) a demonstration study among 265 girls needing ≥ 1 recommended adolescent vaccine and (2) an RCT among 264 boys needing vaccines, with half randomized to recall and half receiving usual care. Immunization rates for recommended adolescent vaccines were assessed 6 months after recall. First dose costs were assessed by direct observation and examining invoices. RESULTS: At the end of the demonstration study, 77% of girls had received ≥ 1 vaccine and 45% had received all needed adolescent vaccines. Rates of receipt among those needing each of the vaccines were 68% (160/236) for tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine, 57% (142/248) for quadrivalent meningococcal conjugate vaccine, and 59% (149/253) for the first human papillomavirus vaccine. At the end of the RCT, 66% of recalled boys had received ≥ 1 vaccine and 59% had received all study vaccines, compared with 45% and 36%, respectively, of the control group (P < .001). Cost of conducting recall ranged from $1.12 to $6.87 per recalled child immunized. CONCLUSIONS: SBHC-based recall was effective in improving immunization rates for all adolescent vaccines, with effects sizes exceeding those achieved with younger children in practice settings.

Inequities in neonatal survival interventions: evidence from national surveys.

BACKGROUND: Nearly four million children die during the first four weeks of life every year, yet known and effective interventions exist. Neonatal mortality has to be addressed to reach the millennium development goal for child survival. AIMS: To determine the extent of within-country inequities in neonatal mortality and effective intervention coverage. METHODS: Neonatal, infant and child (under 2 years) mortality rates were calculated from empirical data from Demographic and Health Surveys for eight countries using direct estimation techniques. Wealth groups were constructed using the World Bank wealth index; neonatal mortality inequities were evaluated by comparing low:high quintile ratios; concentration indices were calculated for intervention coverage rates. RESULTS: The proportion of under-2 deaths occurring in the neonatal period ranged from 24.3% (Malawi) to 49.4% (Bangladesh). In all countries (excluding Haiti) inequities in neonatal mortality and intervention coverage were evident across wealth groups with more deaths and less coverage in the poorest, compared with the richest, quintile; the largest mortality differential was 2.1 (Nicaragua) and the smallest was 1.2 (Eritrea). In Nicaragua 33% of the poorest women had a skilled delivery compared with 98% of the richest; in Cambodia for antenatal care this was 18% (poorest) and 71% (richest). Low coverage of interventions tended to show top inequity patterns whereas high coverage tended to show bottom inequity patterns. CONCLUSIONS: Reducing inequity is a necessary step in reducing neonatal deaths and also total child deaths. Intervention efforts need to begin to integrate approaches relevant to equity in programme design, implementation, monitoring and evaluation.

Neonatal tetanus in Peru: risk assessment with modified enzyme-linked immunosorbent assay and toxoid skin test.

We used a modified enzyme-linked immunosorbent assay (ELISA) to investigate tetanus immunity in 232 pregnant Peruvian women. One hundred forty-two (61.2%) had protective antitoxin titers (> or = 0.01 IU/mL). Protective titers correlated positively with the number of toxoid doses reported during the current pregnancy. A majority of women reporting no toxoid doses during the current pregnancy had at least one prenatal health care visit. We evaluated a toxoid skin test in 44 of the subjects, but it correlated poorly with the ELISA. The modified ELISA is a useful in vitro method for studying tetanus immunity in the developing world.

[Antitetanus prophylaxis: actual practice and cost benefit analysis of a hypothetical mass vaccination]. / Profilassi antitetanica: pratica attuale ed analisi costo-benefici di una ipotesi di vaccinazione di massa.

The actual practice of immunoprophylaxis in a Sanitary District of Campania (Italy) is described. As everywhere in Italy, in subjects at risk (wounded) the passive immunoprophylaxis by human specific immunoglobins is currently applied: at very high cost and with unreliable protection. The Authors suggest to implement antitetanus mass vaccination, with benefits incoming from lower expenses and higher protection.

Tetanus prophylaxis and accidental wounds.

Of 400 consecutive patients who had wounds treated in the Accident Department, 200 remembered receiving either booster injections or a full course of tetanus toxoid in the last 10 years. During this period, 182 patients received their initial toxoid injection in association with treatment of a wound in an accident department. Only 71 (38%) of these patients attended for a full course of injections. From our assessment of the wounds and the patient's anti-tetanus immunity, 79 patients (20%) were considered to be at risk of developing tetanus. By further considering the time interval elapsed between injury and treatment, a 'high risk' group of 13 patients (3%) was recognised. It is recommended that the use of human immunoglobulin should be reserved for the 'high risk' group, and that the remainder of the 'at-risk' patients should receive penicillin prophylaxis only.

Benefits of immunization versus risk factors in tetanus.

The risk of tetanus is universal, but it depends on numerous factors (socio-economic, environmental and biological) which combine to determine the force of infection. Tetanus is a murderous and costly disease. Its morbidity has greatly regressed in industrialized countries (less than 1 case per 100,000, involving mainly aged persons). On the contrary, developing countries are still severely affected (10 to 50 cases per 100,000, involving mainly neonates and children). Tetanus vaccine is one of the most effective, best tolerated and least expensive vaccines. Vaccination is the main weapon for starting disease control in developing countries, and the only way of eradicating tetanus in developed countries. Whatever the socio-economic level may be, some evaluations show that immunization cost is approximately equal to avoided treatment and seroprevention expenditures. The essential benefit of vaccination is the prevention of death, suffering and disability.
