Chylothorax: a complication following lung resection in patients with NSCLC - chylothorax following lung resection.

BACKGROUND: Chylothorax following lung resection is not as rare as a postoperative complication as previously reported due to systematic lymph node dissection in patients undergoing lung resection for NSCLC. METHODS: We retrospectively reviewed our cases that had undergone lung resection for NSCLC and investigated the frequency and outcome of chylothorax in these patients. The factors investigated were the site and type resection, technique of systematic lymph node dissection, tumour histology and disease stage. RESULTS: Seven of 673 patients that had undergone lung resection were complicated by chylothorax (1.04 %), following lobectomy in 5 (1.28 %) and pneumonectomy in 2 (0.7 %) (p = 0.36). The fistula closed spontaneously in 5 patients between 4 - 17 days postoperatively (71 %). One of the patients in the conservative management group died on the 28th day postoperatively due to pneumonia (14 %). The remaining 2 patients underwent rethoracotomy on the 5th and 6th days. CONCLUSIONS: These results suggest that the site of operation, type resection, and technique of systematic nodal dissection, tumour histology and disease stage do not influence the development of chylothorax in patients with NSCLC. The chylous fistula following lung resection for NSCLC tends to close spontaneously.

Shoulder-girdle strength after standard and lateral muscle-sparing thoracotomy.

BACKGROUND: There is no objective data in the literature to support the statement that shoulder-girdle strength can be preserved better after muscle-sparing thoracotomy compared with standard thoracotomy. The aim of this study is to determine the decrease on muscle strength with objective criteria by measuring the peak torque value produced by the shoulder girdle. METHOD: Peak torque values on abduction and adduction of entire shoulder range at the velocity of 60 and 120 degree per second were measured with an isokinetik dynomometer which was attached to a computer. The measurements were performed in 20 cases, all candidates for thoracotomy. Patients were randomised into 2 groups; muscle sparing thoracotomy was undertaken in group A, and standard thoracotomy in group B. The same measurements were repeated 3 months after the surgery. RESULTS: The decrease in postoperative PT values between group A and B was statistically significant (p<0.003). The decrease on shoulder abduction and adduction was insignificant in group A (p = 0.33 and p=0.13) and statistically significant in group B (p<0.0001 and p<0.001). CONCLUSION: These results confirm the statement that shoulder girdle strength is better preserved with muscle-sparing thoracotomy.

A study on polymerase chain reaction-based HLA DQ alpha locus in Elaziğ, Turkey.

The polymerase chain reaction (PCR) was used for genetic characterization of 45 samples taken from the city of Elaziğ in Turkey. The polymorphism at the human leukocyte antigen DQalpha locus was detected. Allele and genotype frequencies were determined for unrelated individuals at this locus. Laboratory analyses were done by PCR amplification of DNA. Hybridization to allele specific oligonucleotide probes was performed using a reversed dot-blot typing method. The collected genotype and allele frequencies have been tested, and a comparison was made with other population surveys of this locus. Allele frequencies ranged from 3.3% (allele 1.3) to 36.7% (allele 4), with a discrimination power of 0.92. No deviation was seen from Hardy-Weinberg equilibrium in the findings.

Axillary hibernoma: an unusual soft tissue tumor.

Hibernomas are rare soft tissue tumors of brown fat differentiation. A case of a large axillary hibernoma, along with a review of its pathology, is presented. This tumor matches the largest hibernoma in the literature and is the largest in an axillary site.

The role of 99Tcm-tetrofosmin myocardial perfusion scintigraphy in the assessment of patients with previous myocardial infarction: a comparative study with 201Tl.

The aim of this study was to determine the utility of 99Tcm-tetrofosmin cardiac imaging in patients with previous myocardial infarction and with significant coronary artery disease (CAD) compared with that of 201Tl cardiac imaging. Sixteen patients (14 males, 2 females) were studied by same-day exercise-rest 99Tcm-tetrofosmin imaging and exercise, rest and reinjection 201Tl cardiac imaging. For each study, semi-quantitative visual analysis was performed in 20 segments using a 4-point scale. The regional distribution and defect reversibility with the two tracers were compared with the results of coronary angiography. A total of 320 segments were analysed. There was a statistically significant concordance between the numbers of fixed and reversible segments in both studies in myocardial segments supplied by totally occluded coronary arteries (Group 1), as well as in segments supplied by significantly stenosed coronary vessels (Group 2). The exercise and rest uptake of both 99Tcm-tetrofosmin and 201Tl in myocardial segments supplied by totally occluded coronary arteries with poor collateral flow was significantly lower compared with segments supplied by totally occluded coronary arteries with efficient collateral flow (P < or = 0.05). When the uptake of both tracers was analysed according to each major vascular territory, the mean exercise and rest uptake grades of 99Tcm-tetrofosmin and 201Tl were similar. There was also no significant difference in defect reversibility between the two tracers. Discordant results were observed in the territory of the right coronary artery in Group 1 (mean exercise grade of 99Tcm-tetrofosmin = 2.26 +/- 0.7 and of 201Tl = 1.92 +/- 0.8; P < or = 0.001) and in Group 2 (mean grade of 99Tcm-tetrofosmin = 0.79 +/- 0.65 and of 201Tl = 0.95 +/- 0.65; P < or = 0.05). The results of the present study indicate that the overall diagnostic utility of 99Tcm-tetrofosmin in the identification of individual stenosed vessels is comparable with 201Tl in both patients with totally occluded coronary arteries and those with significantly stenosed vessels. The regional distribution of both tracers was lower in myocardial segments supplied by totally occluded coronary arteries with poor collateral flow.

Multiple pterygium syndrome.

Severely involved female child with Multiple Pterygium Syndrome (Escobar) is described. She had the typical findings of the syndrome such as multiple pterygiums, characteristic facial appearance, genital anomalies. She also had bilateral optic atrophy. This is the first case described so far with optic atrophy in Multiple Pterygium Syndrome (Escobar).

Prevalence of erythrocyte pyruvate kinase deficiency and normal values of enzyme in a Turkish population.

A pyruvate kinase deficiency prevalence study and determination of the normal levels of the enzyme were performed in Antalya city, Turkey. Heparinized blood samples obtained from a representative population of the Antalya province (617 women and 573 men) were tested for pyruvate kinase deficiency by qualitative and quantitative tests between April 1992 and March 1994. The mean pyruvate kinase activity was found to be 19.8 +/- 4.0 IU/g Hb whereas the enzyme activity of deficient cases varied between 7.5 and 12.2 IU/g Hb. Taking into account that pyruvate kinase deficiency is the second most common cause of nonspherocytic congenital hemolytic anemia, detection of deficient cases by genetic screening tests appears to be an informative clinical indicator of hemolytic anemia.
