Mine Blast Injuries - Our Experience

Background

The sudden increase in incidence and magnitude of mine blast injuries prompted us to highlight the problem and its management.

Methods

The cases of mine blast injuries occurring during mining and demining in a particular geographical area were analysed. Total 27 cases of mine blast injuries occurred during mining or demining operations in a period of 13 months.

Results

Various body regions were involved in the mine blast injuries but the main brunt was borne by feet and legs followed by multiple body regions due to splinters. 14 patients underwent below knee (BK) amputation while 4 patients required through knee (TK) amputations. The effect of blast was so severe that most of the cases required 2 to 5 times wound debridements. The initial aggressive debridement / open stump amputation saved the limb and life of all patients.

Conclusion

A mine blast causes extensive injuries and psychological trauma. Management is needed urgently, surgery is difficult, and amputation is often inevitable. Maximum lives and limbs can be saved with aggressive debridement, repeated inspections and dressings under anaesthesia and definitive closure at optimum time.Key Words: Amputation, Antipersonnel mine, Crush syndrome, Debridements, Mine blast injury, Secondary missiles, Shrapenels     

Is prematurity important in ultrasonographic hip typing?

The aim of this study was to determine whether prematurity is important with respect to hip typing and planning of treatment/follow-up in newborns assessed with the Graf's ultrasonography method. Between January 1998 and 2003, 1592 neonates; preterm (n=432) and term (n=1160), had their hips ultrasonographically evaluated with Graf typing. There were no statistical differences between the two groups with respect to the numbers of hips that required follow-up assessment, or treatment. The results suggest that prematurity is irrelevant and use of chronological age as opposed to corrected age for prematurity will further simplify diagnosis and planning of follow-up and treatment in the Graf system for neonatal hip assessment.     

Relationship between sleep complaints and proinflammatory cytokines in haemodialysis patients

BACKGROUND: Sleep complaints are common in end-stage renal disease. We aimed to investigate the relationship between sleep-related complaints and inflammatory cytokines in haemodialysis (HD) patients, and also the effects of HD on sleep patterns and cytokine levels. METHODS: Predialysis serum interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) levels in nine patients with sleep complaints were compared with those of nine patients without sleep complaints and nine healthy controls. Patients with sleep complaints underwent polysomnography the night after HD and the following night. RESULTS: Patients with sleep complaints had significantly higher predialysis IL-1beta levels compared with those without and healthy controls (P=0.004 and P=0.000, respectively). They also had higher predialysis IL-6 and TNF-alpha levels than those without sleep complaints; however, the difference was not significant. Patients without sleep complaints had higher mean IL-6 and TNF-alpha and similar mean IL-1beta levels compared with healthy controls (P=0.001, P=0.024, P=0.26, respectively). Obstructive sleep apnoea syndrome (OSAS) was found in six out of nine (66%) patients with sleep complaints. Sleep architecture and cytokine levels did not differ between the two nights. The mean serum IL-1beta, IL-6 and TNF-alpha levels did not differ in the pre- and post-polysomnographic samples. There was no correlation between IL-1beta, IL-6 or TNF-alpha levels and the apnoea-hypopnoea index. CONCLUSIONS: Proinflammatory cytokines, IL-1beta in particular, might be associated with sleep complaints in HD patients. OSAS is not uncommon in HD patients with sleep-related complaints and sleep architecture does not appear to be effected by the HD procedure itself.     

Plasma and urine nitric oxide levels in healthy Turkish children

Nitric oxide (NO) is an important messenger molecule with a wide range of actions in virtually all cell systems and organs. In kidneys it participates in glomerular and medullary hemodynamics, tubuloglomerular feed-back, renin secretion, and extracellular fluid balance. Although the role of NO in regulating renal function in adults is well-established, it has recently been suggested that NO has a more critical role in maintaining basal renal blood flow and glomerular filtration rate (GFR) in the developing kidney. NO is rapidly metabolized to the stable end products nitrite and nitrate, which are more slowly excreted into the urine. Thus these metabolites can be recommended as useful markers of endogenous NO synthase activity, despite limited data about age-related changes in in-vivo NO production. The aims of this study were to determine age-related normal reference values of serum and urinary NO metabolites and to assess the probable relationship between these metabolites and the GFR. Normal levels of NO end products in blood and urine of 296 healthy children (117 female, 179 male) between the ages of 0 and 16 were investigated, as was whether these values change with age. Serum and urinary nitrate levels did not differ according to sex. Serum nitrate levels are higher in younger children, especially in the newborn period, and decrease with age. Nitrate levels in urine are higher in younger children with a peak in infancy (1 month to 1 year) and decrease with age. It was demonstrated that this decrease in serum and urinary nitrate levels with age parallels the increase in GFR. In conclusion, urinary NO products may be an indirect marker of serum NO levels and NO might have an important regulatory function both in the maintenance of renal function and in the maturation of the developing kidneys.     

Nonmelanoma skin cancer

Each year, there are as many cases of nonmelanoma skin cancer as all other cancers combined. Although there is relatively low attributable mortality, the morbidity and expense of treatment is significant. Unlike many other malignancies, host and environmental factors relevant to the pathophysiology have been clearly demonstrated. Surgical ablation remains the mainstay of treatment.     

Scintigraphic diagnosis of tricuspid regurgitation

The authors describe a simple technique for diagnosis of tricuspid regurgitation. Red blood cells were labeled in vivo with 99mTc and 22 patients were studied with ECG-gated blood-pool imaging of the liver. A single region of interest was manually drawn around the liver and a time-activity curve obtained. The per cent change in liver counts during the cardiac cycle was found to be significantly higher in the 12 patients with tricuspid regurgitation (Group I) (mean, 4.04 +/- 1.6%; range, 1.3-21.4%) compared with the 10 controls (Group II) (mean, 0.35 +/- 0.16%; range, 0.013-1.3%) (p less than 0.05). Using a 1% change in liver counts as the criterion of a positive study, all 12 cases in Group I were diagnosed correctly, but there was one false positive in Group II; thus the sensitivity was 100% and the specificity 90%.
