BACKGROUND: The external jugular vein (EJV) is a useful intravenous (IV) cannulation site for anesthesiologists, although it has a relatively high failure rate. Unlike other central veins, visualization of the EJV is important during IV cannulation, and the Valsalva maneuver distends the jugular venous system. However, the relationship between the maneuver and EJV visibility remains unknown. This study compared EJV visibility before and after the Valsalva maneuver. METHODS: This was a prospective observational study that included 200 participants. After the induction of anesthesia, EJV visibility grade, depth from the skin to the EJV superficial surface (EJV depth), and EJV cross-sectional area (CSA) before the Valsalva maneuver were measured. The same parameters were measured after the Valsalva maneuver was performed. The EJV visibility grade was defined as grade A: good appearance and good palpation, grade B: poor appearance and good palpation, and grade C: poor appearance and poor palpation. RESULTS: Patient body mass index and EJV depth affected the EJV visibility grade before the Valsalva maneuver (p < 0.05), although EJV CSA did not. The Valsalva maneuver distended EJV CSA and reduced EJV depth, although these changes were not correlated with EJV visibility grade. With regard to EJV visibility, 34.0% of grade B cases and 20.0% of grade C cases were improved by the Valsalva maneuver. CONCLUSIONS: Although the Valsalva maneuver improved EJV CSA and EJV depth, it did not greatly affect EJV visibility grade.

C-erbB-2 oncoprotein has been known to act as growth factor receptor responsible for the regulation of cellular growth, proliferation and differentiation and has been demonstrated in a number of cancers by immunohistochemical as well as matrix blotting techniques. Breast and ovarian cancer patients, whose tumor cells have amplification or overexpression of this oncoprotein, have been suggested to have worse prognosis. Yet, there are only a few studies on c-erbB-2 oncoprotein expression in transitional cell carcinoma(TCC) of the bladder. The aim of this study was to examine c-erbB-2 oncoprotein expression in bladder cancer to assess its potential as a useful prognostic marker in transitional cell carcinoma of the bladder. Deparaffinized tumor specimens from 42 patients with TCC of the bladder and 3 normal bladder tissue specimens were utilized. C-erbB-2 oncoprotein expression was detected by immunohistochemical analysis and then correlated with conventional prognostic variables such as histologic tumor grade, stage and DNA ploidy. In addition, we related the expression of c-erbB-2 oncoprotein to indicators of cellular proliferative activities such as proliferating cell nuclear antigen(PCNA), mean number of silver nucleolar organizer regions(AgNORs) per nucleus, flow cytometric S-phase fraction(CPF) and proliferation index(PI). The incidence of c-erbB-2 oncoprotein expression in Ash grade IV TCC of bladder was higher than that in Ash grade II and III (Chi-square test, p<0.05). The incidence of positive immunoreaction was higher in cases with muscle invasion and metastasis than in superficial tumors with statistical significance(p<0.05). In addition, statistical significant correlation was noted between c-erbB-2 oncoprotein expression and PCNA expression rate. But there were no significant differences in c-erbB-2 oncoprotein expression to DNA ploidy, PI nor SPF by flow cytometry and mean number of AgNORs per nucleus. The results of this study suggests that the c-erbB-2 oncoprotein together with other predictive parameters may serve to provide a phenotypic profile which permits more accurate forecasting of bladder cancer behavior and may prove to be useful in the future as an important guide to specific anti-tumor therapy.

To clarify neuronal connection of the medial rectus muscle at brain stem, Bartha strain of the psecudorabies virus(PRV-Ba) and cholera toxin-horeserdish peroxidase(CT-HRP) was injected into medial rectus muscle of the rat. About 84 hours after PRV or CT-HRP injection, the brain was removed and processed immunohistochemical stain for PRV-Ba and neurohistochemical stain for CT-HRP using tetramethyl benzidine. The CT-HRP positive reaction was only present in ipsilateral oculomotor nucleus, contralateral abducence nucleus and bilaterally in rostral interstitial nucleus of medial longitudinal fasciculus, olivary pretectal nucleus, medial and superior vestibular nucleus, nucleus prepositus hypoglossi, prerubral field, nucleus Darkschewitsch, lateral substantia nigra, terminal nucleus of accessory nucleus, dorsal raphenucleus, locus ceruleus and pontime reticular formation. This study confirmed that both oculomotor nucleus and abducence nucleus were connected with each other through the medial longitudinal fasciculus, and neuronal connection of the medial rectus muscle in the rat brain stem.

Cataract operation was carried out in 7 glaucomatous eyes with prolonged ocular hypotony after trageculectomy with intraoperative mitomycin C. In all cases, The postoperative intraocular pressure(IOP) rose and the postopeative average IOP was 6.0+/-2.0mmHg higher than their preoperative average IOP. The preexisting bleb was reduced in size eyes that underwent phacoemulsification and posterior chamber intraocular lens(PC-IOL) implantation. But. It was not changed in extracapsular cataract extraction and IOL implantation. In our study, cataract operation in eyes that had lens opacity with prolonged hypotony induced IOP rise and was beneficial to hypotony.

Dyke-Davidoff-Masson syndrome is a rare disorder which developed hemiatrophy of brain, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. It manifests hemiparesis, varying type seizure, and mental retardation. We experienced two cases of Dyke-avidoff-Masson Syndrome, in a 6/12 year-old boy and a 1, 10/12 year-old girl who were admitted to our department of pediatrics, because of convulsion and hemiparesis The brain CT scan showed marked dilatation of lateral ventricle, prominent sylvian fissure and cortical sulci. So we report two cases of Dyke-Davidoff-Masson syndrome with review of literature.

BACKGROUND: Current non-invasive methods for evaluating the mediastinum by computed tomographic(CT) scan have limited sensitivity and specificity. The recently introduced PET was reported to be a more sensitive and specific method for the mediastinal staging of NSCLC(sensitivity:76-100%, specificity:81-100%) than CT or MRI. We assessed the usefulness of PET in the mediastinal staging of NSCLC. METHODS: We reviewed the medical records of NSCLC patients that had undertaken staging work-up by both CT and PET before thoracotomy between January 1997 and December 1998. A total of 23 patients were enrolled in the study(14 males and 7 females) with a mean age of 61±9 years. By comparing the clinical(CT and PET) and pathologic stagings, we evaluated the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of PET in thoracic nodal staging. RESULTS: Sensitivity, specificity, positive predicted value and negative predicted value were 38%, 40%, 25% and 50% respectively for computed tomography, and 50%, 60%, 30% and 69% for PET. The accuracy of FDG-PET in our study was lower than that reported by previous other studies. CONCLUSION: Tne addition of FDG-PET to CT scanning has limited benefit for the thoracic nodal staging of NSCLC, but its value in our study was lower than that observed by others.
