The causes of burn wounds among adult patients treated at Pelonomi Tertiary Hospital, Bloemfontein.

BACKGROUND: Burn injuries account for approximately 180 000 deaths per annum, mostly in low- and middle-income countries. METHOD: This was a prospective, cross-sectional study. The target population consisted of adult patients, hospitalised for burn wounds at Pelonomi Tertiary Hospital in Bloemfontein, between July 2016 and early January 2017. Relevant data was collected by means of a structured interview using a questionnaire. RESULTS: A total of 49 patients were interviewed during the study period. Almost two-thirds of the patients were male (65.3%, n=32). The median age was 33 years (range 18 to 64 years). In most cases, the injury occurred at home (77.6%, n=38). Three quarters of the reported incidents (77.6%, n=38) were considered accidental of which 68.4% (n=26) were related to domestic activities. At the time of the accidental incident, 39.5% (n=15) patients had consumed alcohol. Eleven (22.4%) of the incidents were intentional with 63.6% (n=7) attributed to assault. The two main causes of burn injuries were flames including flaming liquids (59.2%, n=29) and hot liquids (22.5%, n=11). The most frequent area of injury was the left front thigh. CONCLUSION: The predominant cause of burn wounds was flames including flaming liquids, and injuries were mostly accidental in nature. Alcohol consumption and domestic activities were common in accidental burns.

Maternal near-miss audit in the Metro West maternity service, Cape Town, South Africa: A retrospective observational study.

BACKGROUND: A maternal near-miss is defined as a life-threatening pregnancy-related complication where the woman survives. The World Health Organization (WHO) has produced a tool for identifying near-misses according to criteria that include the occurrence of a severe maternal complication together with organ dysfunction and/or specified critical interventions. Maternal deaths have been audited in the public sector Metro West maternity service in Cape Town, South Africa, for many years, but there has been no monitoring of near-misses. OBJECTIVES: To measure the near-miss ratio (NMR), maternal mortality ratio (MMR) and mortality index (MI), and to investigate the near-miss cases. METHODS: A retrospective observational study conducted during 6 months in 2014 identified and analysed all near-miss cases and maternal deaths in Metro West, using the WHO criteria. RESULTS: From a total of 19 222 live births, 112 near-misses and 13 maternal deaths were identified. The MMR was 67.6 per 100 000 live births and the NMR 5.83 per 1 000 live births. The maternal near-miss/maternal death ratio was 8.6:1 and the MI 10.4%. The major causes of near-miss were hypertension (n=50, 44.6%), haemorrhage (n=38, 33.9%) and puerperal sepsis (n=13, 11.6%). The first two conditions both had very low MIs (1.9% and 0%, respectively), whereas the figure for puerperal sepsis was 18.9%. Less common near-miss causes were medical/surgical conditions (n=7, 6.3%), non-pregnancy-related infections (n=2, 1.8%) and acute collapse (n=2, 1.8%), with higher MIs (33.3%, 66.7% and 33.3%, respectively). Critical interventions included massive blood transfusion (34.8%), ventilation (40.2%) and hysterectomy (30.4%). Considering health system factors, 63 near-misses (56.3%) initially occurred at a primary care facility, and the patients were all referred to the tertiary hospital; 38 (33.9%) occurred at a secondary hospital, and 11 (9.8%) at the tertiary hospital. Analysis of avoidable factors identified lack of antenatal clinic attendance (11.6%), inter-facility transport problems (6.3%) and health provider-related factors (25.9% at the primary level of care, 38.2% at secondary level and 7.1% at tertiary level). CONCLUSIONS: The NMR and MMR for Metro West were lower than in other developing countries, but higher than in high-income countries. The MI was low for direct obstetric conditions (hypertension, haemorrhage and puerperal sepsis), reflecting good quality of care and referral mechanisms for these conditions. The MIs for non-pregnancy-related infections, medical/surgical conditions and acute collapse were higher, suggesting that medical problems need more focused attention.

The causes of burn wounds among adult patients treated at Pelonomi Tertiary Hospital, Bloemfontein

Background: Burn injuries account for approximately 180 000 deaths per annum, mostly in low- and middle-income countries. Aim: This study sought to determine the causes of burn wounds among adults admitted to the Burn Wound Unit at Pelonomi Tertiary Hospital in Bloemfontein for treatment.Methods: This was a prospective, cross-sectional study. The target population consisted of adult patients, hospitalised for burn wounds at Pelonomi Tertiary Hospital in Bloemfontein, between July 2016 and early January 2017.

Late death after extracorporeal membrane oxygenation for congenital diaphragmatic hernia.

PURPOSE: The aim of this study was to determine the long-term outcome of neonates who required extracorporeal membrane oxygenation (ECMO) for respiratory insufficiency associated with congenital diaphragmatic hernia (CDH). METHODS: All neonates born with CDH, who required ECMO (oxygenation index over 40 in the presence of maximal support) during a 6-year period, were reviewed. The median duration of follow-up for survivors was 14 months (range, 9 to 22 months). RESULTS: Of 72 neonates with CDH, 11 (15%) required ECMO. The median age at the start of ECMO was 2 days (range, 1 to 4); duration was 9 days (range, 4 to 17); post-ECMO ventilation was 27 days (range, 8 to 86); and stay in intensive care unit, 33 days (range, 8 to 133). Three patients survived and are not oxygen dependent. There were three early deaths at 9 to 16 days and five late deaths at a median of 6 months (range, 2 to 32 months) secondary to chronic lung disease (n = 3) and infection (n = 2). Four of the five patients with late deaths were oxygen dependent at discharge from hospital. Three of the late death patients and one survivor underwent a fundoplication for gastrooesophageal reflux. CONCLUSIONS: Neonates born with CDH and requiring ECMO had a significant late mortality. Follow-up for more than 1 year is indicated to assess the benefit of ECMO for this diagnosis. The authors report only three long-term survivors from 11 ECMO patients selected from a total of 72 neonates with CDH.

A randomized study of radiotherapy alone versus radiotherapy plus 5-fluorouracil and platinum in patients with inoperable, locally advanced squamous cancer of the esophagus.

Squamous cell cancer of the esophagus is the most common cancer among black South African males, and 60% of patients present with localized inoperable disease. Combined chemoradiotherapy has been reported to be superior to radiotherapy alone for localized inoperable esophageal cancer in North American patients. A study was carried out to determine if this was also applicable to South African patients, who present with more advanced disease. From September 1991 through June 1995, 70 patients with locally advanced (T3N0-1M0) squamous cancer of the esophagus were prospectively randomized to receive radiotherapy alone or radiotherapy combined with cisplatin and 5-fluorouracil. There was no statistically significant survival difference between the two groups. The median survival was 144 days in the group receiving radiotherapy alone, and 170 days in the group receiving radiotherapy combined with chemotherapy (p = 0.42). The degree of weight loss before initiation of therapy had a significant effect on survival regardless of the treatment arm. Radiotherapy in combination with chemotherapy, as administered in this study for South African patients with locally advanced, inoperable squamous cancer of the esophagus, is no better than radiotherapy alone.

13-Cis-retinoic acid and interferon alpha-2a in patients with advanced esophageal cancer: a phase II trial.

The aim of this study was to investigate the possible therapeutic effect of 13-cis-retinoic acid plus interferon alpha-2a in patients with inoperable squamous cancer of the esophagus. Patients with advanced, measurable, histologically confirmed squamous carcinoma of the esophagus with an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2 who had adequate bone marrow, liver, and renal function were eligible for study. Patients were given cis-retinoic acid 1 mg/kg/day per mouth continuously and interferon alpha-2a 3 Mu/day for 3 days followed by 6 Mu subcutaneously daily thereafter. Seventeen patients were entered on study. Fifteen patients were evaluable for toxicity. The most common toxicities were grade 1 and 2 cheilitis, dry skin and flu-like symptoms which occurred in all patients. Two patients had grade 3 toxicity (1 anorexia and 1 fatigue). No grade 4 toxicity occurred. Fifteen patients were evaluable for response. No objective response was documented. The median survival time was 15 weeks. With no response seen it is unlikely that the combination of treatment as used in this study will be of benefit in patients with advanced squamous cancer of the esophagus.

The value of radiotherapy or chemotherapy after intubation for advanced esophageal carcinoma--a prospective randomized trial.

After intubation for advanced, inoperable squamous carcinoma of the oesophagus, a prospectively controlled randomized trial was done to investigate the effect of radiotherapy (41 patients) or mono-chemotherapy (40 patients) or no further treatment (46 patients). Treatment had no significant effect on either palliation or survival (p < or = 0.7) and did not alter the natural history of the disease.

A phase II study of 5-fluorouracil and leucovorin in advanced carcinoma of the esophagus.

Thirty-five patients with advanced epidermoid carcinoma of the esophagus were treated with 5-fluorouracil (5-FU) 425 mg/m2 and leucovorin 20 mg/m2, day 1-5 every 28 days. Six patients had a partial response (95% confidence limit, 7-35%) with a median response duration of 32 weeks. The median survival time of the patients on study was 14 weeks. The toxicity was acceptable, with only two patients experiencing severe hematologic toxicity and one patient experiencing severe nausea and vomiting. The addition of leucovorin at this dose level in this population of patients with advanced disease does not appear to enhance the activity of 5-FU for patients with squamous cell cancer of the esophagus. Since only a small percentage of patients experienced significant toxicity, a higher response rate could be achieved in patients treated with the maximally tolerated dose.
