Pleural involvement by hydatid cysts of the lung

Hydatid cyst disease is encountered in Turkey frequently. Rupture of a pulmonary cyst into the pleural cavity is rare, but represents the most serious complication of the hydatid disease. Surgical intervention was carried out in all cases in our clinic when expansion of the lungs could not be achieved. Open ends of the bronchus were closed and the pericyst layer was sutured after the removal of the germinative layer. We here present 5 cases of hydatid cysts with the above mentioned complication.     

Comparison of the nuclear matrix protein 22 with voided urine cytology in the diagnosis of transitional cell carcinoma of the bladder

Several urinary markers for transitional cell carcinoma have been investigated, including urine cytology, bladder tumor antigen, autocrine motility factor receptor and fibrin degradation products. Unfortunately, they have poor overall sensitivity. The United States Food and Drug Administration have recently approved nuclear matrix protein (NMP 22) for the detection of occult or rapidly recurring disease after transurethral resection of bladder tumor. The objective of the current study was to assess the sensitivity of NMP 22 for the detection of bladder carcinoma, as well as to correlate the NMP 22 values with multiplicity of tumor, tumor size, configuration, stage and grade respectively. A total of 78 patients (38 with bladder cancer) provided a urine sample which was divided into appropriate aliquots for each of urine cytology and NMP 22. Comparative results demonstrate a clear superiority of NMP 22 in bladder cancer detection (52.6% vs 31.6% sensitivity), while specificity was in favor of urine cytology (100% vs 82.5%). For superficial tumors, sensitivity was 78.5% for NMP 22 and 41.6% for cytology and for invasive cancers, sensitivity was 90% for NMP 22 and 60% for cytology. Urinary NMP 22 levels were significantly correlated with tumor grade and were significantly higher in large tumors than small tumors. NMP 22 test results showed sufficient sensitivity in comparison with urine cytology for the detection of transitional cell carcinoma. However, we do not think that it is a useful tool as a substitute for endoscopic examination for the detection and surveillance in bladder cancer.     

Sports activities after medial unicompartmental knee arthroplasty Oxford III—What can we expect?

Purpose

Excellent long-term results have been reported for implantation of unicompartmental knee arthroplasty (UKA). In many patients the desire for improvement in function often includes an aspiration to return to sports. The purpose of our study was to evaluate physical activities after medial Oxford-III (Biomet) UKA surgery.

Methods

Patients’ physical activity before and after the surgery was assessed using a self reporting questionnaire. We used the Oxford knee scoring system (OKS), the WOMAC-, the Knee society- (KSS) and the UCLA-score to assess postoperative knee function. The mean follow-up was 4.2 years. The female-to-male ratio was 1.3:1. The mean age at surgery was 65.3 years.

Results

Of the 131 patients studied 78 participated in some kind of sports before surgery (mean age 64.4 years), while 53 patients did not perform any sports (mean age 66.5 years) (p > 0.05). At follow-up the patients in the active group were significantly younger than the patients in the inactive group (p < 0.05). The majority of patients (80.1 %) returned to their level of sports activity after UKA surgery. Six patients took up sports after surgery while 15 patients stopped their sports. Among the active patients we found a shift from high- towards low-impact sports. The active patients had significantly higher scores for the OKS, KSS, WOMAC and UCLA score. The complication rate was comparable in both groups.

Conclusion

Our study demonstrates that a high degree of patient satisfaction in terms of sports activity can be achieved using the Oxford-III UKA for medial osteoarthritis.     

Arthroscopic meniscal repair using T-fix

We evaluated the arthroscopic meniscal repair using T-fix and present our preliminary results. The series included 47 consecutive patients who underwent meniscal repair using T-fix. Mean follow-up was 26 months (range 12-42 months). The overall number of T-fixes used in the repairs was 163, with a mean of three (range two to five) per patient. Patients were evaluated according to the modified Marshall scoring system. Results were rated as excellent in 32, good in 10, fair in 2, and poor in 3 patients. Second-look arthroscopy was performed in 18 patients as the part of our protocol. In 15 patients meniscal tears were considered to be healed, according to Henning's criteria. Six of those who underwent anterior cruciate ligament reconstruction healed completely. There were no neurovascular complications. Repair of the menisci using T-fix proved successful and reliable. In view of satisfactory functional results and the observation of healing of tears on second-look arthroscopy, we believe that preservation and repair of menisci should be attempted in appropriate cases.     

Clinical and cognitive insight in patients with acute-phase psychosis: Association with treatment and neuropsychological functioning

Background: The severity of psychopathology cannot fully explain deficits in the multi-dimensional construct of insight.

Aims: The aim of this study was to evaluate the correlates and associations of clinical and cognitive insight in patients in an acute phase of psychosis and to analyse the impact of acute treatment on these variables.

Methods: This study examined 47 inpatients who were recently hospitalized with acute exacerbation of schizophrenia. All subjects were assessed at both admission and discharge with the Positive and Negative Syndrome Scale (PANSS), Schedule for the Assessment of Insight-Expanded Version (SAI-E), Beck Cognitive Insight Scale (BCIS), and a neurocognition battery.

Results: Patients with schizophrenia gained clinical insight after treatment. Cognitive insight did not change significantly after treatment. Insight showed significant negative correlations with positive symptoms and general psychopathology, but not with negative symptoms. Clinical insight was not associated with neuropsychological functioning in this cohort.

Conclusion: Gaining clinical insight in the acute phase of illness was associated with the remission of positive symptoms, but not with neuropsychological functioning. Some significant correlations between clinical and cognitive insights were detected, which suggests that cognitive insight contributes to clinical insight but is not treatment-dependent. Long-term treatment may be required to understand the contribution of insight to the outcome of patients with schizophrenia.     

Combined approach for far-lateral lumbar disc herniation

This study evaluated the combination of the classical interlaminar approach and the intertransverse route through a midline approach for the treatment of 18 patients with far-lateral lumbar disc herniations, as identified by magnetic resonance imaging. The patients presented with acute severe sciatica, antalgic posture, positive Lasègue sign and femoral stretch test, motor and sensory deficits, and reflex loss findings. Discectomy of all 18 patients was performed by the combined approach. Neurological outcome of all patients was excellent in the follow-up period, ranging from 5 to 8 years. This combined midline approach permits complete evacuation of the involved disc level and treatment of additional bone resection procedures. Therefore, we advocate this approach in far-lateral lumbar disc herniation cases.     

Revascularization of multiple bypassable extended right coronary arteries

BACKGROUND: Extended right coronary arteries are not uncommon in coronary surgery. They can be revascularized optionally either by conventional single or complete multiple bypassing. However, there are still no objective data showing the superiority or appropriateness of one of these methods over the other. METHODS: Extended right coronary arteries were identified by preoperative angiographic scoring and randomized to multiple-bypassing (group A; n = 32) or single-bypassing (group B; n = 32) groups. Four parameters that show the completeness of right coronary territory revascularization were evaluated and compared between the 2 groups. RESULTS: Although overall perioperative ischemic events seemed to increase in the single-bypass group (P =.0059), half of them were reversible, and there were no statistical differences between the definitive perioperative ischemic event rates, namely, infarction rates, and the remaining 3 parameters of the groups. Logistic regression analysis showed that preoperative left ventricular dysfunction (ejection fraction <50%) was the most significant predictor of these perioperative ischemic events. Hence, the subgroups of patients with left ventricular dysfunction were also evaluated (subgroup A, n =13; subgroup B, n = 12). Overall perioperative ischemic event (P =.001), definitive perioperative ischemic event (infarction; P =.0324), and consequent right ventricular dysfunction (P =.0324) rates were significantly higher in the single-bypass subgroup. Postoperative reperfusion status and graft patency rates of the right coronary territory did not change with the different revascularization methods. CONCLUSIONS: Complete revascularization of extended right coronary arteries did not seem advantageous over its conventional operation in patients with normal ventricular function; however, in patients with poor ventricular function (ejection fraction <50%), it prevented perioperative ischemic events in the right coronary territory and the consequent functional impairment that appeared with conventional operation.     

Anesthesia for proteus syndrome

Proteus syndrome is a complex disorder comprising malformations and overgrowth of multiple tissues. The disorder is highly variable affecting tissues in a mosaic pattern. A 2-year-old boy with Proteus syndrome, with epidermal verrucal naevus, hyperplastic lesions of connective tissue, hyperostosis, overgrowth of tubular bones, bilateral inguinal hernia, and juvenile intestinal polyposis was scheduled for vertebral magnetic resonance imaging (MRI) for further evaluation of malignancies. In addition to the pathological findings of this syndrome, potential complications such as difficult intubation, pulmonary hypertension, and pulmonary thromboembolism necessitate a careful preoperative and anesthetic preparation. MRI was performed under general anesthesia. There were no anesthetic complications. There are few previous reports on anesthesia in a patient with Proteus syndrome.
