Scalding in Turkish children: comparison of burns caused by hot water and hot milk

INTRODUCTION: Our aim in this study was to compare the clinical differences and etiologic risk factors for hot water and hot milk scald burns in Turkish children. METHODS: The retrospective study examined the cases of 140 children aged 0.1-7 years who had scald burns treated in three burn units of a Turkish hospital network between March 2000 and December 2004. The patients were categorized in two groups: hot water burns or hot milk burns. RESULTS: Ninety-five (67.9%) patients had hot water burns and 45 (47.1%) had hot milk burns. The proportion of patients with hot milk burns who lived in rural areas was significantly higher than the corresponding proportion for the hot water cases (75.6% versus 52.6%, respectively; p<0.01). In 20 (44%) of the hot milk cases, the burn was caused by milk being boiled in large pots outdoors for cheese production. The other 25 hot milk cases were caused by milk being boiled in the kitchen. The mean (+/-S.D.) percentage total body surface area burned in the hot milk cases was higher than that in the hot water cases (33.6+/-2.24% versus 21.42+/-1.43%, respectively; p<0.001), and the corresponding mean percentages of TBSA with full-thickness burns were 9.2+/-2.52% versus 3.13+/-0.83%, respectively; (p=0.083). The mean percentages of TBSA with second-degree burns showed the same trend (29.0+/-12.39% versus 18.8+/-1.47%, respectively; p<0.001) higher percentage of the children with hot milk burns required antibiotics (78% versus 52.8%, respectively; p<0.006). Seven (7.4%) of the hot water burn patients and 15 (33.3%) of the hot milk burn patients died during the study period (p=0.025; overall mortality rate 15.7%). CONCLUSION: Children scalded with hot milk tend to have more extensive burns, and thus have higher mortality, than those scalded with hot water. To create effective programs for preventing scald injuries in Turkey and elsewhere, it is essential to consider ethnic and cultural issues based on these characteristics. Simple precautions should be explained and methods of using liquids such as hot milk should be researched in different geographic locations in order to formulate good prevention strategies.     

Craniovertebral junction Pott's disease

Pott's disease of the craniovertebral junction is extremely rare. The authors studied the immediate and long-term outcome after transoral decompression, occipitocervical stabilization with fusion and antitubercular therapy (ATT) in patients who had neurological deficits due to craniovertebral junction (CVJ) tuberculosis. This is a retrospective study of the management and outcome in 10 consecutive patients in whom features of spinal cord (with or without) compression were observed, and CVJ tuberculosis was diagnosed in two different neurological departments between 1990 and 2002. They ranged in age from 15 to 72 years. The onset of symptoms was either acute or subacute. Patients presented with neck and occipital pain (90%), progressive tetraparesia (40%), sensory symptoms (40%), neck stiffness (30%) and urinary dysfunction (20%). The disease caused spinal cord compression in six patients, atlantoaxial dislocation in five patients, basilar impression in one and upper vertebral column destruction without dislocation in three. Two patients presented with multiple spinal tuberculosis. Antitubercular therapy was used in all cases for 15 months. Surgical treatment performed in all patients. Four patients underwent transoral drainage of retropharyngeal abscess with granulation tissue and one odontoidectomy. Six patients then underwent occipitocervical (occiput -C3 or -C4) fusion with insertion of titanium plate and screw. Postoperatively, ATT was prescribed for 15 months. At long-term follow-up (median 50.2 months), functional status considerably improved. Two patients died 2 months later due to myocardial infarction. Patients with CVJ with features of cervical myelopathy are ideally treated with transoral decompressive procedures followed by occipitocervical fusion, because this therapy provides immediate neurological improvement, stability and allows early mobilization. The long-term prognosis in patients with this disease is excellent, provided it is treated with appropriate surgical intervention and with adequate duration of ATT. This approach provides excellent access to this region, with a low operative morbidity and no mortality.

Biocompatibility of heparin-coated cardiopulmonary bypass circuits in coronary patients with left ventricular dysfunction is superior to PMEA-coated circuits

BACKGROUND: Several coating techniques for extracorporeal circulation have been developed to diminish the systemic inflammatory response during cardiopulmonary bypass (CPB). The aim of this study was to evaluate the clinical effectiveness and biocompatibility of heparin-coated and poly-2-methoxyethylacrylate (PMEA)-coated CPB circuits on coronary patients with left ventricular systolic dysfunction. METHODS: Thirty-six patients who underwent elective coronary artery bypass grafting were divided into two equal groups: group H (n = 18), heparin-coated; group P (n = 18), PMEA coated. Clinical outcomes, hematologic variables, cardiac enzymes, malondialdehyde (MDA), and acute phase inflammatory response (including myeloperoxidase (MPO), catalase, hsCRP, and IL-8) were analyzed perioperatively. RESULTS: Demographic, CPB, and clinical outcome data were similar for both groups. Plasma fibrinogen, total protein, albumin, and platelet count decreased, neutrophil count, MDA, IL-8, MPO, and catalase levels increased during CPB. During CPB, MPO and catalase values were significantly higher in group P (p = 0.02 and p = 0.01) and postoperative MDA concentration was lower in group H (p = 0.03). Platelet counts were better preserved in group H during and after CPB but neutrophil count and IL-8 level did not differ between the groups. Postoperative total protein, albumin, and fibrinogen levels were higher in group H (p < 0.05). The postoperative first day levels of troponin-I, CK-MB, and CRP increased in both groups without any significant differences between the groups. CONCLUSIONS: Heparin-coated circuit provided better suppression of perioperative inflammatory markers and exhibited more favorable effects on hematologic variables than PMEA-coated circuit.     

Radiological and clinical comparisons of the patients with rheumatoid arthritis operated with rigid and dynamic instrumentation systems due to lumbar degenerative spinal diseases

BackgroundIt is extremely difficult to treat spine disorders with stabilization in patients with rheumatoid arthritis. Because revision rates are significantly higher in rigid stabilization. To date, there is no data about patients with rheumatoid arthritis treated with dynamic stabilization. Our aim was to compare the radiological and clinical results of patients with rheumatoid arthritis who underwent lumbar rigid stabilization or dynamic stabilization with Polyetheretherketone rod (PEEK).MethodsPatients with degenerative lumbar spine disease with rheumatoid arthritis who underwent dynamic stabilization between 2013 and 2015 and rigid stabilization between 2010 and 2012 were evaluated radiologically for adjacent segment disease, proximal junctional kyphosis, system problem (nonunion, screw loosening, instrumentation failure, pull out). It was also compared according to both the revision rates and the Visual Analog Scale and Oswestry Disability Index scores at the 12th month and 24th month.ResultsThe difference of decrease in Visual Analog Scale and Oswestry Disability Index scores from preoperative to 12th month between patients who underwent dynamic stabilization and rigid stabilization was statistically insignificant. However, there was a significant difference of increase in Visual Analog Scale and Oswestry Disability Index scores between the 12th month and 24th month of patients who underwent rigid stabilization, compared with patients with dynamic stabilization. In patients with dynamic stabilization, the problems of instrumentation were seen less frequently. Revision rates were high in patients with rigid stabilization when compared the patients with dynamic stabilization.ConclusionRadiological and clinical outcomes in patients with rheumatoid arthritis operated with dynamic stabilization are more significant when compared to rigid stabilization. These patients have lower pain and disability scores in their follow up periods. Revision rates are lower in patients with dynamic stabilization.     

The Intraneural Hemangioma of the Digital Nerve: Case Report

Intraneural Hemangioma of the digital nerve is rare and so far three cases have been reported in the literature. We present a case of 12- year- old boy with painless soft tissue mass in the right hand and numbness on the radial aspect of the index finger. Magnetic Resonance Imaging showed an isointense subcutaneous lesion without discrete borders in the first web space classically of hemangioma with the radial digital nerve extension. On exploration, the intraneural extension of the hemangioma was confirmed and total resection, microsurgical primary digital nerve repair was done. The patient became better and at 6 months follow up the index finger sensation improved. The patient had no reccurence and he is still under follow up.     

Predicting intraoperative feasibility of combined TES-mMEP and cSSEP monitoring during scoliosis surgery based on preoperative neurophysiological assessment

Background contextCombined monitoring of muscle motor evoked potentials elicited by transcranial electric stimulation (TES-mMEP) and cortical somatosensory evoked potentials (cSSEPs) is safe and effective for spinal cord monitoring during scoliosis surgery. However, TES-mMEP/cSSEP is not always feasible. Predictors of feasibility would help to plan the monitoring strategy.PurposeTo identify predictors of the feasibility of TES-mMEP/cSSEP during scoliosis surgery.Study design/settingProspective cohort study in a clinical neurophysiology unit and pediatric orthopedic department of a French university hospital.Patient sampleA total of 103 children aged 2 to 19 years scheduled for scoliosis surgery.Outcome measuresFeasibility rate of intraoperative TES-mMEP/cSSEP monitoring.MethodsAll patients underwent a preoperative neurological evaluation and preoperative mMEP and cSSEP recordings at both legs. For each factor associated with feasibility, we computed sensitivity, specificity, positive predictive value (PPV), and negative predictive value. A decision tree was designed.ResultsPresence of any of the following factors was associated with 100% feasibility, 100% specificity, and 100% PPV: idiopathic scoliosis, normal preoperative neurological findings, and normal preoperative mMEP and cSSEP recordings. Feasibility was 0% in the eight patients with no recordable mMEPs or cSSEPs during preoperative testing. A decision tree involving three screening steps can be used to identify patients in whom intraoperative TES-mMEP/cSSEP is feasible.ConclusionsPreoperative neurological and neurophysiological assessments are helpful for identifying patients who can be successfully monitored by TES-mMEP/cSSEP during scoliosis surgery.     

Taurine attenuates lung ischemia–reperfusion injury after lung transplantation in rats

Purpose

Taurine, the major intracellular free amino acid found in high concentrations in mammalian cells, is known to be an endogenous antioxidant and a membrane-stabilizing agent. It was hypothesized that taurine may be effective in reducing ischemia–reperfusion injury after lung transplantation and an experimental study was conducted in a rat model.

Methods

The number of Sprague–Dawley rats used in the study was 35. Animals were randomized into five groups of 7 rats each, including control, donor I, donor II, ischemia–reperfusion injury, and treatment groups. All animals were exposed to the same experimental conditions in the preoperative period. Rats were fixed in a supine position after the induction. After the rats were shaved, a left pneumonectomy was performed following sternotomy in control, donor I, and donor II groups. The harvested grafts in donor I and donor II groups were transplanted to the rats of the ischemia–reperfusion group and treatment group, respectively. However, taurine was administered intraperitoneally for 3 days before the harvesting procedure in donor II. All harvested lungs were kept in a Euro-Collins solution at +4 °C for 24 h in a half-inflated manner. After harvesting and transplantation, lungs were sampled for histopathological and biochemical analysis.

Results

Malondialdehyde and superoxide dismutase, glutathione peroxidase, and catalase levels were lower in the treatment group than the other groups (p < 0.05). Histopathological findings were better in treatment group than the ischemia–reperfusion group (p < 0.05).

Conclusion

It was demonstrated that donor treatment with taurine resulted in preservation of transplanted lung tissue in respect to histopathological and biochemical findings.     

Hypothenar island flap: A safe and excellent choice for little finger defects

Soft-tissue defects of the little finger are challenging especially when bone, tendon or vascular pedicle is exposed because of trauma. The hypothenar island flap is easy to harvest and has a good colour and texture match to the little finger pulp. We present nine clinical cases of soft tissue defects of the little finger covered using the reversed hypothenar fasciocutaneous island flap. This article intends to highlight the ease of elevation and good clinical results of the hypothenar flap which is rarely used.KEY WORDS: Hypothenar island flap, island flap, soft-tissue defects of the little finger     

Neuroanatomy of cervical sympathetic trunk: A cadaveric study

To reduce the risk of iatrogenic injury to sympathetic chain during anterior and anterolateral approaches to the cervical spine, its location has to be well defined and known by surgeons. We analyzed the course of sympathetic chain and its ganglia from C7 up to its entry into the cranial base and its relationship mainly with the longus colli (LC). Formalin fixed 20 human cadavers were dissected under operating microscope. Measurement of the dimensions of the ganglia, distance of the trunk to the LC, and the angles identifying the course of the chain were performed. Superior and inferior cervical/cervicothoracic ganglion were observed in all specimens, the middle cervical ganglion was observed in 48% of the specimens. The middle ganglion consisted of two ganglia in 10% of the dissected sides. Forty percent of the inferior cervical/cervicothoracic ganglion was at the C7 level, 25% was at C7‐Th1 disc level, and 35% was at Th1 level. Vertebral ganglion was detected in only 8% of the specimens. The course of the sympathetic trunk converges medially descending from upper cervical levels to the lower levels. Anterior surgical approach to the cervical spine is a commonly used procedure. Although Horner syndrome due to sympathetic injury is not a common sequence of cervical operations, our findings support the current few reports on the subject and should be useful to any surgeon who operates in the cervical region to avoid this uncommon complication.
