Nd:YAG laser therapy for rectal and vaginal venous malformations.

BACKGROUND: Limited therapeutic options exist for rectal and vaginal venous malformations (VM). We describe our center's experience using Nd:YAG laser for targeted ablation of abnormal veins to treat mucosally involved pelvic VM. METHODS: Records of patients undergoing non-contact Nd:YAG laser therapy of pelvic VM at a tertiary children's hospital were reviewed. Symptoms, operative findings and details, complications, and outcomes were evaluated. RESULTS: Nine patients (age 0-24) underwent Nd:YAG laser therapy of rectal and/or vaginal VM. Rectal bleeding was present in all patients and vaginal bleeding in all females (n = 5). 5/7 patients had extensive pelvic involvement on MRI. Typical settings were 30 (rectum) and 20-25 W (vagina), with 0.5-1.0 s pulse duration. Patients underwent the same-day discharge. Treatment intervals ranged from 14 to 180 (average = 56) weeks, with 6.1-year mean follow-up. Five patients experienced symptom relief with a single treatment. Serial treatments managed recurrent bleeding successfully in all patients, with complete resolution of vaginal lesions in 40% of cases. No complications occurred. CONCLUSIONS: Nd:YAG laser treatment of rectal and vaginal VM results in substantial improvement and symptom control, with low complication risk. Given the high morbidity of surgical resection, Nd:YAG laser treatment of pelvic VM should be considered as first line therapy.

Pediatric surgical care in Lilongwe, Malawi: outcomes and opportunities for improvement.

BACKGROUND: One of the objectives of the Millennium Development Goals is to improve child health. We describe the burden of pediatric surgical disease at a tertiary hospital in Malawi. METHODS: We conducted a retrospective analysis of a pediatric surgery database at Kamuzu Central Hospital in Malawi for the calendar year 2012. Variables included patient demographics, admission diagnosis, primary surgery and outcome. RESULTS: A total of 1170 pediatric patients aged 0-17 years were admitted to the surgical service during the study period. The mean age was 6.9 years, and 62% were male. Trauma was the most common indication for admission (51%, n = 596), and 67% (n = 779) of all patients were managed non-operatively. Neonates and patients managed non-operatively had a significantly increased risk of mortality. CONCLUSION: Only a third of patients admitted to the pediatric surgery service underwent surgery. More than half of patients with congenital anomalies did not undergo surgical intervention. Importantly, patients who underwent surgery had a survival advantage.

Epidemiology of pediatric injury in Malawi: burden of disease and implications for prevention.

PURPOSE: Pediatric injuries pose a significant health burden in sub-Saharan Africa, though historic data are too scarce to appreciate the extent of the problem. The purpose of this study is to utilize a comprehensive database to describe the epidemiology of pediatric injuries at a tertiary hospital in Malawi. METHODS: Data were prospectively collected on patients presenting to the emergency department for treatment of injuries from 2008 to 2010 (n = 23,625). The subset of pediatric patients (n = 7233) underwent cross-sectional analysis to examine demographics, injury environment, timing and mechanisms. RESULTS: Pediatric patients, (0-16 years) comprised 30.6% of all trauma patients. Mean age was 7.2 years. Falls were the most common injury (43%), followed by burns (11.1%), pedestrian road traffic injuries (9.7%), foreign bodies (7.5%), and assaults (7.2%). Statistically significant differences in injury pattern were observed between gender, age groups and season. After logistic regression, predictors of fall included male gender, home setting, and rainy season, whereas predictors of burn included female gender, age 0-5 yrs, home setting, and cold season. Predictors of pedestrian injury included age 6-10 yrs, female, and roadside setting. Predictors of foreign body ingestion included age 0-5 yrs, female gender, home setting, and daytime, and predictors of assault include male gender, age 11-16 yrs, nighttime hours. All predictors were statistically significant (p < 0.05). CONCLUSIONS: This study revealed patterns of injury based upon age, gender, location, and season. Our results may prove useful to stakeholders in injury prevention for designing, evaluating, and implementing programs to improve public safety in children in Malawi and similar resource poor nations.
