Prospective study of methodological issues in intracranial pressure monitoring in patients with hydrocephalus

OBJECT: Continuous intracranial pressure (ICP) monitoring is performed in selected patients with hydrocephalus to determine whether shunt placement is required. The mean ICP is usually calculated from end-hour readings manually recorded by nurses. The aim of this study was to evaluate the accuracy of manual recordings by comparing nurses' end-hour ICP readings with those of an online computerized ICP monitoring system that records one ICP value per second. METHODS: Continuous ICP monitoring was performed using a fiberoptic extradural sensor in 115 patients with hydrocephalus of different origins. A notebook computer was connected to an ICP monitor and was programmed to register one ICP value per second. In all patients, mean ICP values were calculated from data recorded manually by nurses at the end of every hour and from data recorded by the computer within the preselected time period. The two methods were compared using correlation analysis and the Bland and Altman method. The median number of ICP values noted manually by the nurses in each patient was 17 (interquartile range 15-18 readings), and that recorded by the software was 61,200 (interquartile range 54,000-64,800 readings). The correlation coefficient of the mean ICP values recorded by both methods was r = 0.99 (p < 0.001). The Bland and Altman analysis revealed a mean difference of 0.3 +/- 1.26 mm Hg between the two methods and that they were equally valid with all mean ICP values. CONCLUSIONS: The recording of end-hour ICP values by nurses is an accurate method of calculating the mean ICP after prolonged ICP monitoring in patients with hydrocephalus.     

Is the placement of shunts in patients with idiopathic normal-pressure hydrocephalus worth the risk? Results of a study based on continuous monitoring of intracranial pressure

OBJECT: Data from many studies have demonstrated that shunt insertion in patients with idiopathic normal-pressure hydrocephalus (NPH) is associated with high morbidity and a lack of significant improvement; however, the use of strict diagnostic and treatment protocols can improve the results of surgery in these patients. The primary aim in this prospective study was to analyze the results of shunt placement in 43 patients with idiopathic NPH. A secondary aim was to determine the relationship between several clinical and neuroimaging factors, and patient outcome after surgery. METHODS: Thirty men and 13 women with a mean age of 71.1 +/- 6.9 years participated in this study. All patients underwent clinical, neuropsychological, and radiological assessment before and 6 months after surgery. In all patients continuous monitoring of intracranial pressure was performed using a fiberoptic extradural sensor. In 31 patients cerebrospinal fluid dynamics were also determined. Eighty-six percent of patients showed clinical improvement after shunt insertion, 11.6% showed no change, and 2.3% exhibited some worsening. Gait improved in 81.4% of the patients, sphincter control in 69.8%, and cognitive dysfunction in 39.5%. There was no treatment-related death. Early or late postsurgical complications occurred in six patients (14%), although all of these complications were minor or were satisfactorily resolved. The complete clinical triad, cortical sulci size, and periventricular lucencies were related to outcome, whereas patient age, symptom duration, ventricular dilation, and the degree of presurgical dementia were unrelated to outcome. CONCLUSIONS: Given the correct diagnosis, shunt insertion can produce marked improvement in patients with idiopathic NPH syndrome, causing few deaths and few clinically relevant complications.     

The effects of local and sustained release of fibroblast growth factor on testicular blood flow and morphology in spermatic artery--and vein-ligated rats

Background/purpose

This study was carried out to evaluate the effects of local and sustained release of fibroblast growth factor (FGF) on testicular blood flow and morphology in spermatic artery— and vein-ligated rats.

Methods

Forty male Wistar albino rats weighting 300 ± 20 g were allocated randomly into 5 groups consisting of 8 in each as follows: G-S (sham); G-C (control); and G-T_0.85, G-T_1.70, G-T_2.55. After the ligation of the left spermatic artery and vein, 1 cm² of unloaded and 0.85 μg, 1.70 μg, and 2.55 μg of FGF-loaded gelatin films were sutured on the left epididymis in G-C, G-T_0.85, G-T_1.70, and G-T_2.55, respectively. After 30 days, bilateral capsular (CBF) and intratesticular (IBF) blood flows were evaluated by colored Doppler ultrasonography (CDUS) and testicular blood flow (TBF) by ¹³³Xe clearance technique. Tunica albuginea and intertubular tissues were studied for the increase of peritesticular and intratesticular vessels. Mean intertubular vascular structure counts, seminiferous tubular diameters, testicular biopsy scores, and Leyding cell scores of each group were recorded and compared.

Results

CBF was present in all animals of G-S, G-T_0.85, G-T_1.70, and G-T_2.55 groups in CDUS, and it was detected in 62% of the G-C rats (P < .05). However, IBF was present in only 25% of the G-C rats, and this percentage was increased from 50% up to 87.5% for treatment groups, and 100% for G-S rats, respectively. ¹³³Xe clearance showed that TBF was significantly decreased in G-C compared with G-S (P < .05). In G-T_2.55, TBF was significantly increased, but still could not reach the level of G-S. Although mean testicular weights were significantly decreased for controls (G-C), G-T_0.85, and G-T_1.70, almost no difference was observed between G-T_2.55 and G-S. Although a slight increase in the vascular structures of tunica albuginea was present in G-C rats, a significant increase was observed in treatment groups. The mean number of intertubular vascular structures was significantly increased in treatment groups when compared with G-S and G-C (P < .05). Mean seminiferous tubular diameters and Leydig cell scores were decreased in G-C but significantly increased in treatment groups (P < .05). Mean testicular biopsy scores were increased in treatment groups compared with G-C but could not reach to sham levels.

Conclusions

Ligation of the spermatic artery and vein has detrimental effects on the ipsilateral testicular blood flow and morphology. These effects may be reversed by local application of FGF.     

Health care professionals' knowledge of procedural issues in transplantation: the need for continuing education programs

Organ transplantation is a multidisciplinary field that requires a good knowledge of the processes and excellent cooperation throughout the entire hospital. The aim of this study was to determine the level of knowledge of health care professionals (HCPs) at our transplantation center concerning general definitions and procedural issues related to transplantation. A questionnaire including nine items-five questions on general definitions and four on procedural issues-was distributed to 100 randomly selected HCPs. Four participants were excluded because they completed the questionnaire incorrectly; thus, there were 96 total respondents. The mean number (+/-SD) of correct answers overall was 5.78 +/- 1.36. Concerning general definitions, 11.5% of the respondents answered all of the questions correctly. However, the corresponding rate for the procedural questions was 3.1%. One percent of the respondents answered 1 or zero definition questions correctly, and 19.8% answered 1 or zero procedural questions correctly. The HCPs showed better knowledge of general issues related to transplantation than procedural issues. The results of this study suggest that the knowledge of HCPs in transplantation centers in Turkey is limited to the extent that their specialty is linked to transplantation. It is important that continuing medical education programs be instituted in organ procurement and transplantation centers in Turkey. These in-service training programs would enhance HCPs' understanding of and participation in procedures related to transplantation, and thus improve the total quality of the transplantation process.     

Phenomenon of calcification of the stylohyoid ligament

Patients with continuous pain in the pharynx were examined roentgenologically for calcification of the stylohyoid ligaments and the styloid process. Symptoms and surgical outcomes are described in cases with calcification of the stylohyoid process and muscle. Surgical treatment eliminated pain, noise in the ears, chronic pharyngeal inflammation. No recurrences occurred. Histological examination of the removed stylohyoid ligaments detected calcificated hyalin plaques in these ligaments.     

Prognostic significance of Ki-67 expression for patients with laryngeal squamous cell carcinoma primarily treated by total laryngectomy

The aim of this study was to determine the prognostic value of Ki-67 immunostaining in laryngeal squamous cell carcinomas. Ki-67 labeling was quantified in 63 laryngeal squamous cell carcinomas by counting at least 1,000 tumor cells in the most immunoreactive area in each sample, and the Ki-67 labeling index was calculated as a percentage. The antigen expression was compared with clinical factors, histopathological grading and prognosis. The Ki-67 mean proliferation index for all patients was 25.44% ( range, 2–75%). A significant correlation was found between Ki-67 mean proliferation index and patient age (P<0.05), T-stage (P<0.05), nodal metastasis (P=0.001) and recurrence (P<0.001). There was no significant association between the Ki-67 mean proliferation index and tumor site or histologic grade. A univariate analysis showed that the Ki-67 labeling index >21% (P<0.001), T-stage (P<0.001) and nodal metastasis (P=0.001) are determinants of recurrence. In the multivariate analysis, the Ki-67 labeling index >21% (P<0.001), T-stage (P<0.001) and nodal metastasis (P<0.05) were independent predictors of recurrence. Kaplan-Meier plots of survival in patients with Ki-67 values above and below the median (21%) of the general study population showed that a high Ki-67 labeling index correlated with a shorter disease-free survival (P<0.0001). The analysis of the Ki-67 labeling index at the time of initial surgery may be a powerful prognostic marker for patients with laryngeal squamous cell carcinoma and may be useful for selecting subgroups of patients who should be treated with more aggressive therapies.     

Prevalence of endometriosis in malignant epithelial ovary tumours

OBJECTIVE: To determine the prevalence of ovarian endometriosis in malignant epithelial ovarian tumours. STUDY DESIGN: A retrospective analysis of 160 malignant and 23 borderline ovarian tumours during the period 1995-2001. RESULTS: Fourteen (7.7%) of the tumours contained endometriosis. This affected 22% of the endometrioid and 10.8% of the mixed adenocarcinomas. The mean age of the ovarian endometriosis patients was 43+/-13 range 26-70 years. The incidence in borderline tumours 13% (3/23) was higher than that in ovarian cancer 6.9% (11/160) (P>0.05). Eight (57%) of cases were classified as atypical and six (43%) as typical endometriosis. Nine cases were FIGO (International Federation of Gynaecology and Obstetrics) stage I and 5 stage III. CONCLUSIONS: Both malignant and borderline ovarian tumours are associated with ovarian endometriosis. In addition, atypical endometriosis was found associated with endometrioid and mixed epithelial ovarian tumours.     

A morphometric study on the humerus for intramedullary fixation

In recent years, the popularity of intramedullary humeral nailing is on the rise in spite of its handicaps. There are many problems in intramedullary humeral stabilization because of the anatomic structure of the bone. We performed various methods and measurements to determine shape, length and diameter and curvature of the medullary canal of the humerus in 57 human dry cadaver bones. Anterior angulation with an average of 21 cm apart from greater tubercle was found at 1/3 distal part. Mean degree of angulation was 9 degrees (max: 15, minutes: 5, S.D.: 2.84). Humerus bones with septal aperture (supratrochlear foramen) at the fossa coronoidea were observed to have very narrow medullary canal. The best point for nail insertion was found to be an area on the line from greater tubercle anteromedially to caput humeri. This study revealed that carefully evaluated structure of humeral medullary canal and various congenital constructions such as septal aperture, and correct selection of a nail with proper length and diameter are essential for successful nailing.     

Comparison of fentanyl-bupivacaine or midazolam-bupivacaine mixtures with plain bupivacaine for caudal anaesthesia in children

BACKGROUND: The aim of this study was to evaluate the intensity and effectiveness of 0.75 ml.kg-1 bupivacaine 0.25% with the addition of fentanyl or midazolam for caudal block in children undergoing inguinal herniorrhaphy. METHODS: Seventy-five children were allocated randomly to three groups to receive a caudal block with either 0.25% bupivacaine with fentanyl 1 microg.kg(-1) (group BF) or with midazolam 50 microg.kg(-1) (group BM) or bupivacaine alone (group B) after induction of anaesthesia. Haemodynamic parameters, degree of pain, additional analgesic requirements and side-effects were evaluated. RESULTS: The mean systolic arterial pressure at 10, 20, 30 min after caudal block was higher in group B compared with groups BF and BM. Mean intraoperative heart rate was lower in group BF than the other groups. Adequate analgesia was obtained in all patients (100%) in group BF, 23 patients (92%) in group BM and 21 patients (84%) in group B (P > 0.05). The time to recovery to an Aldrete score of 10 was significantly shorter in group B than group BM (P < 0.05). Although not significant, it was also shorter in group B than group BF. There was no difference in additional analgesic requirements between the groups in the first 24 h. Sedation score was higher in the midazolam group at 60 and 90 min postoperatively than the other groups. CONCLUSIONS: Caudal block with 0.75 ml.kg(-1) 0.25% bupivacaine and 50 microg.kg(-1) midazolam or 1 microg.kg(-1) fentanyl provides no further analgesic advantages to bupivacaine alone when administered immediately after induction of anaesthesia in children undergoing unilateral inguinal herniorrhaphy.
