Comparison of the Adult Comorbidity Evaluation 27 and the Charlson Comorbidity indices in patients with laryngeal squamous cell carcinoma.

OBJECTIVE: This study aimed to compare the prognostic impact of comorbidity grading by the Adult Comorbidity Evaluation 27 index and the Charlson Comorbidity Index on the five-year overall and disease-specific survival in patients undergoing surgery for laryngeal squamous cell carcinoma. METHODS: The impact of comorbidity and other factors on survival was examined retrospectively in a group of 177 patients with previously untreated tumour stage one to four laryngeal squamous cell carcinoma surgically treated at the Clinic of Otorhinolaryngology and Maxillofacial Surgery, Clinical Centre of Serbia, between 2000 and 2003. The Cox proportional hazard model was used to identify independent prognostic factors. RESULTS: On univariate analysis, comorbidity had an impact on prognosis regardless of which index was used. On multivariate analysis, the significant predictors of patients' five-year overall and disease-specific survival were tumour-node-metastasis stage and comorbidity as graded by the Adult Comorbidity Evaluation 27 index. CONCLUSION: The Adult Comorbidity Evaluation 27 index is a more reliable predictor of survival than the Charlson Comorbidity Index in patients with laryngeal squamous cell carcinoma.

[Hemodynamic effect of local infiltrative 2% lidocaine adrenaline anesthesia in general balanced anesthesia during middle ear surgery].

Hemodynamic effect of different techniques and type of anesthesia are defined. The volume of reduced hemorrhage in surgical field is debatable, without any definite conclusion. The objective of the study is to investigate the effects of local infiltrative anesthesia with adrenaline during general balanced anesthesia and nitroglicerol on blood presure and hemorrhage reduction in middle ear operations. Prospective, randomized study included 58 adult patients planned for the otorhinolaryngological surgery. Studied group of patient (n 30) planned for middle ear operations. Befora incision surgeon was administered local infiltrative anesthesia using 2% lidocaine with adrenaline (1:200,000) The controls group (n 28), planned for other surgery had no local infiltrative anesthesia with adrenaline. Hemodinamic parameters were monitored before surgical incision and 30 minutes after that. Surgeon's verbal reply on hemorrhage reduction during surgery was recorded. Statistical analysis of parametric data was carried out by Mann-Whitney sum test. Blood pressure and heart rate was not different between the two groups. But, intraoperatively, the study showed lowering of sistolic and diastolic blood pressure. This mode of treatment and surgeon's verbal reply confirmed that local infiltrative anesthesia with adrenaline under balanced anesthesia had no effect on hemorrhage reductionin surgical field.

Elevated serum uric acid reduce heart damage in patients undergoing opern-heart surgery.

OBJECTIVES: Peroxynitrite is species claimed to propagate ischemia/reperfusion damage. In this report levels of serum uric acid (UA), a peroxynitrite scavenger, are compared with creatine phosphokinase (CPK) in male patients before and after open-heart surgery in order to asses if increased levels of UA may protect heart from biochemical damage induced by peroxynitrite during the coronary by-pass grafting (CABG) intervention. METHODS: 45 male patients (16 carvedilol pretreated (6.25 mg/ daily, during 6 weeks before surgery, mean age 55.3+/-1.7 years, range 50-71) and 29 patients without carvedilol pretreatment (mean age 58.3+/-1.4 years, range 47-73) underwent elective CABG were examined. Study inclusion criteria were CABG performed on two and more coronary-vessels with aortic cross-clamp during 30-40 minutes. For assessment of patients objective health status before operations EuroSCORE were used. Serum uric acid (UA) levels and creatine phosphokinase (CPK) were measured spectrophotometricaly by using a quantitative enzymatic assay. RESULTS: Carvedilol pretreated patients had higher amount of serum UA (p<0.05) comparing to non-treated patients. During the surgical procedure patients are subjected to temporary ischemia due to transfer from corporeal to extracorporeal circulation. In this period of time the amount of UA decreased in carvedilol pretreated group (406+/-46 (tl) vs. 300+/-22 mmol/L (t2)) to the level of non-treated patients (328+/-14 (t1) vs. 322+18 mmol/L. Carvedilol pretreated patients and non-treated patients had the same level of CPK at the beginning of the surgical procedure (tl) (78+/-6 vs. 83+13 U/L) but lower increase (p<0.05) in CPK activity in carvedilol pretreated patients in respect to non-treated patients (338+46 vs. 644+103 U/L) at the end of procedure (t2). Such results suggest that open heart surgery led to elevated CPK levels, but this effect was less pronounced in patients with higher level of UA. CONCLUSIONS: Our results suggest possible role of UA in the protection from reperfusion injury. Increase of UA before surgery may be beneficial factor during CABG procedure in patients treated with carvedilol by decreasing level of peroxynitrite as one of molecular causes of reperfusion injury. Our results showed influence of UA on CPK levels at the end of surgical procedure, indicating that increased levels of UA may protect heart from biochemical damage induced by peroxynitrite during the CABG intervention.

Patient with double cancer--successfully treated.

INTRODUCTION: Etiology of thrombosis in malignant diseases is multifactorial, and mechanisms that lead to thrombosis include release of the procoagulants from tumor cells (PC), factor related to bed rest, infections, as well as oncological therapy --chemotherapy, hormones, radiotherapy and surgical treatment. Thrombocytosis has frequently been found to be associated with various malignancies. CASE REPORT: 53 years old female patient hospitalised because of hypopharingeal cancer with metastasis in the left neck. Her state was complicated with deep leg vein trombosis and pseudomonas infection. Persistent thrombocitosis in laboratory monitoring indicated more adequate diagnostic procedures, which led to discovering of Chorioidal Malignant Mellanoma as a second cancer. She was treated: surgically, with antibiotics, with anticoagulants and radiotherapy. Patient was discharged from the hospital in good health condition, free of any other symptom of the malignant disease. CONCLUSION: Presense of thrombocytosis and idiopatic thrombosis can suggest occult malignancy. It would be prudent to further evaluate the relationship of trombotic events, trombocitosis and head and neck tumors. We suggest anticoagulants to prevent thromboembolic complications, affect the angiogenesis and prevent development of metastatic disease. It may lead to lower mortality rate.

[Partial resection of the spleen and spleno-renal shunt in the treatment of portal hypertension with splenomegaly and hypersplenism]. / Parcijalna resekcija slezine i spleno-renalni sant u lecenju portne hipertenzije sa splenomegalijom i hipersplenizmom.

Some of serious hepatic diseases with cirrhosis may be complicated by portal hypertension, splenomegaly and hypersplenism. Splenomegaly inhibits regenerative processes of the liver, and also intensifies sequestration of the cellular components of blood up to hypersplenism. Cytopenia caused by hypersplenism is aggravated by negative hepatic influence on bone marrow activity-hemathopoesis, and also by recurrent bleeding from oesophageal varices, and from the other site of gastrointestinal tract. This circle of pathologic conditions may be interrupted only by liver transplantation, until which patients are jeopardized by acute bleeding and chronic anemia. Partial resection of the spleen and splenorenal shunt may correct portal hypertension and hypersplenism, prevent gastrointestinal bleeding, and alleviate hepatic regenerative processes inhibition. In this study, 51 patients with partial resection of the spleen and splenorenal shunt, were analyzed.

We have presented all the pathologic formations on breast treated in our service, with the special accent given to malign formations, the number of which is indisputably growing. The systematical prevention and the early detection of the disease were not done in time what is most important for the prognosis and success of treatment. All patients are postoperatively directed to radiation and cytostatic therapy.
