Abstract
OBJECTIVE To compare outcomes between patients with primary external ventricular device (EVD)-driven treatment of intracranial hypertension and those with primary intraparenchymal monitor (IP)-driven treatment. METHODS The CENTER-TBI study is a prospective, multicenter, longitudinal observational cohort study that enrolled patients of all TBI severities from 62 participating centers (mainly level I trauma centers) across Europe between 2015 and 2017. Functional outcome was assessed at 6 months and a year. We used multivariable adjusted instrumental variable (IV) analysis with "center" as instrument and logistic regression with covariate adjustment to determine the effect estimate of EVD on 6-month functional outcome. RESULTS A total of 878 patients of all TBI severities with an indication for intracranial pressure (ICP) monitoring were included in the present study, of whom 739 (84%) patients had an IP monitor and 139 (16%) an EVD. Patients included were predominantly male (74% in the IP monitor and 76% in the EVD group), with a median age of 46 years in the IP group and 48 in the EVD group. Six-month GOS-E was similar between IP and EVD patients (adjusted odds ratio (aOR) and 95% confidence interval [CI] OR 0.74 and 95% CI [0.36-1.52], adjusted IV analysis). The length of intensive care unit stay was greater in the EVD group than in the IP group (adjusted rate ratio [95% CI] 1.70 [1.34-2.12], IV analysis). One hundred eighty-seven of the 739 patients in the IP group (25%) required an EVD due to refractory ICPs. CONCLUSION We found no major differences in outcomes of patients with TBI when comparing EVD-guided and IP monitor-guided ICP management. In our cohort, a quarter of patients that initially received an IP monitor required an EVD later for ICP control. The prevalence of complications was higher in the EVD group. PROTOCOL The core study is registered with ClinicalTrials.gov , number NCT02210221, and the Resource Identification Portal (RRID: SCR_015582).

Abstract
Introduction Neurocognitive problems associated with posttraumatic stress disorder (PTSD) can interact with impairment resulting from traumatic brain injury (TBI). Research question We aimed to identify neurocognitive problems associated with probable PTSD following TBI in a civilian sample. Material and methods The study is part of the CENTER-TBI project (Collaborative European Neurotrauma Effectiveness Research) that aims to better characterize TBI. For this cross-sectional study, we included patients of all severities aged over 15, and a Glasgow Outcome Score Extended (GOSE) above 3. Participants were assessed at six months post-injury on the PTSD Checklist-5 (PCL-5), the Trail Making Test (TMT), the Rey Auditory Verbal Learning Test (RAVLT) and the Cambridge Neuropsychological Test Automated Battery (CANTAB). Primary analysis was a complete case analysis. Regression analyses were performed to investigate the association between the PCL-5 and cognition. Results Of the 1134 participants included in the complete case analysis, 13.5% screened positive for PTSD. Probable PTSD was significantly associated with higher TMT-(B-A) (OR = 1.35, 95% CI: 1.14–1.60, p < .001) and lower RAVLT-delayed recall scores (OR = 0.74, 95% CI: 0.61–0.91, p = .004) after controlling for age, sex, psychiatric history, baseline Glasgow Coma Scale and education. Discussion and conclusion Poorer performance on cognitive tests assessing task switching and, to a lesser extent, delayed verbal recall is associated with probable PTSD in civilians who have suffered TBI. Six months after traumatic brain injury 13.5% of people screen positive for PTSD. Task switching performance and verbal memory are related to probable PTSD. PTSD severity is related to processing speed and task switching performance.

Abstract
Intubation, which requires sedation and myorelaxants, may lead to inaccurate neurological evaluation of severely head-injured patients. Aims of this study were to describe the early clinical evolution of traumatic brain injured (TBI) patients admitted to intensive care unit (ICU), to identify cases of over-estimated neurological severity, and to quantify the risk factors for this over-estimation. A total of 753 TBI patients consecutively admitted to ICU of three academic neurosurgical hospitals (NSH) were assessed. Cases whose severity was potentially over-estimated were identified by four criteria and indicated as "mistakenly severe" (MS): (1) no surgical intracranial masses; (2) could not follow commands at neurological assessment; (3) were dismissed from the ICU in < or =3 days to a regular ward; and (4) had regained the ability to obey commands. A total of 675 patients were intubated and/or sedated-paralyzed at the post-stabilization evaluation. In all, 304 patients had surgically treated intracranial masses. Among the 449 non-surgical cases, 58 patients fulfilling the criteria for MS were identified. The main features distinguishing MS from truly severe cases were younger age, higher Glasgow Coma Scale (GCS) score at all time points, Marshall classification of Computerized Tomographic (CT) scan mostly Diffuse Injury I and II, fewer pupillary abnormalities, and a lower frequency of hypoxia, hypotension, and extra-cranial injuries. In a certain proportion of non-surgical TBI patients, mostly intubated and sedated, neurological examination is difficult and severity can be over-estimated. Risk factors for this inaccurate evaluation can be identified, and clinical decisions should be based on further examination.

Abstract
OBJECTIVE To set up an index for the evaluation of type of interventions and procedures applied a prerequisite for the evaluation of appropriateness of ICU's activity. DESIGN Observation prospective study. PATIENTS 2507 patients out of the 5030 enrolled in the cohort study. MEASUREMENTS A cross-sectional assessment of the volume and intensity of treatment--level of care--delivered to patients was performed at a preidentified index day. A check list of procedures was utilized. Intensive high level treatment was demonstrated by the application of procedures suggesting one or more organs or vital functions intensively supported. Sub-intensive treatment was defined by the application of procedures indicating monitoring or treatments not exclusively performed in intensive environment. RESULTS 3955 samples were collected over 9 index days; 2707 (68.3%) resulted in intensive, 1227 (30.7%) subintensive or intermediate and 41 (1%) ward treatments. Out of the intensive samples, 63.4% received only one intensive procedure, while 27.9% two. Ventilatory support was the most frequently (90.4%) utilized intensive procedure. Overall 99% of the samples were characterized by treatments/procedures too invasive for normal ward. CONCLUSIONS The proposed method gives the opportunity to easily evaluate the level of care and then the appropriateness of ICU care.

Abstract
We investigated the effects of prone position on functional residual capacity (FRC), the mechanical properties (compliance and resistance) of the total respiratory system, lung and chest wall, and the gas exchange in 10 anesthetized and paralyzed obese (body mass index more than 30 kg/m2) patients, undergoing elective surgery. We used the esophageal balloon technique together with rapid airway occlusions during constant inspiratory flow to partition the mechanics of the respiratory system into its pulmonary and chest wall components. FRC was measured by the helium dilution technique. Measurements were taken in the supine position and after 15-30 min of prone position maintaining the same respiratory pattern (tidal volume 12 mL/kg ideal body weight, respiratory rate 14 breaths/ min, fraction of inspired oxygen [FIO2]0.4). We found that FRC and lung compliance significantly (P < 0.01) increased from the supine to prone position (0.894 +/- 0.327 L vs 1.980 +/- 0.856 L and 91.4 +/- 55.2 mL/cm H2O vs 109.6 +/- 52.4 mL/cm H2O, respectively). On the contrary, the prone position reduced chest wall compliance (199.5 +/- 58.7 mL/cm H2O vs 160.5 +/- 45.4 mL/cm H2O, P < 0.01), thus total respiratory system compliance did not change. Resistance of the total respiratory system, lung, and chest wall were not modified on turning the patients prone. The increase in FRC and lung compliance was paralleled by a significant (P < 0.01) improvement of PaO2 from supine to prone position (130 +/- 31 vs 181 +/- 28 mm Hg, P < 0.01), while PaCO2 was unchanged. We conclude that, in anesthetized and paralyzed obese subjects, the prone position improves pulmonary function, increasing FRC, lung compliance, and oxygenation.

Abstract
OBJECTIVE To assess and to follow along the time-span of ICU stay the process of resources allocation and utilization. DESIGN Prospective study. PATIENTS A cohort of 778 patients consecutively admitted to 7 multipurpose general ICU in the Milano area were enrolled in a survey of the daily performed interventions/procedures. MEASUREMENTS AND MAIN RESULTS The majority of diagnostic procedure/interventions were performed during the first two days. The number and quality of interventions were transferred into points obtaining a score system in non-monetary units. The resource allocation process shows a regular trend in the sub-intensive patients who were only monitorized. On the contrary the 258 patients who were intensively treated and survived show a phase of high resource-consumption (about 30 daily points: roughly twice the score of monitorized patients) then followed by a post-intensive phase with a resource consumption resulting in a daily score absolutely equal to the sub-intensive patients. The intensive patients who die show a significantly higher score than survived patients. Both daily and cumulative scores do not show differences among different type of patients. CONCLUSION The evaluation of the process of resources allocation, even if in non-monetary units enables the knowledge of the trend of ICU costs and allows the elaboration of the appropriate budget mechanism.

Abstract
OBJECTIVE The Intensive Care Units of Milano metropolitan area are characterized by difficulties of hospitalization for acutely injured patients due to the low bed availability. We evaluated the problem trying to find out possible solutions. DESIGN On the day of achieved neurological and neurosurgical stability-defined as the day when the intracranial pressure and jugular venous oxygen saturation monitoring, hyperventilation, osmotic therapy were considered no longer needed--the monitoring procedures and instrumental and/or pharmacological treatments that the patients received were recorded and classified as follows: 1) intensive, 2) intermediate, 3) non-intensive. PATIENTS All the acutely injured patients admitted at five Neurosurgical ICUs during June-July and October-November 1994 have been studied. Only one of these ICUs had a "sub-intensive unit". MEASUREMENTS AND MAIN RESULTS 391 patients (29.9%) aneurysms and arteriovenous malformations, 25.1% tumours, 2.8% head injuries, 8.7% spontaneous intracranial haematomas, 13.5% various pathologies) were studied. Out of them 358 had an acute brain failure. 16.5% died during brain failure and 83.5% reached neurological stability within 3 days. When neurological stability was reached 32.1% of patients could be classified as "intensive", 63.6% as "intermediate" and 4.3% as "unintensive". In the four ICUs, without sub-intensive ward facilities, 361 patients were admitted with a total amount of 2292 days of hospitalization. Among them 61.9% were spent for a) patients with no brain injury (32 pts/113 days), b) postoperative patients (113 pts/167 days), c) patients in stable neurological conditions (159 pts/1139 days). Therefore, only 38% of the days recorded were given to patients that needed neurointensive care. CONCLUSION Out data suggest that the receptivity for acute injured patients could be increased creating recovery room units and intermediate post-intensive units together with a better interchange between general and neurosurgical ICUs.

Abstract
OBJECTIVE To describe a generalized myopathic disorder occurred in the convalescence phase of illness of a critically ill patient. SETTING Neurological Intensive Care Unit. PATIENT A 43-year-old man with acute leukoencephalopathy and severe sepsis complicated by sustained and prolonged cardiovascular, respiratory and renal failure. After 15 days of complete respiratory autonomy, the patient presented an acute ventilatory failure associated with generalized muscle weakness. Neither a relapse of sepsis nor neurological worsening were detected. MEASUREMENTS AND RESULTS Electromyogram resulted in normal conduction velocity in both motor and sensitive nervous fibers. Muscular biopsy showed marked fiber size variability with several hypotrophic fibers type II fiber grouping, several areas of degeneration-necrosis with macrophage invasion, dishomogeneous oxidative enzymatic activity, no increase in glycogen or lipid content. CONCLUSIONS These results excluded critical illness polyneuropathy and all the other known myopathies. Prolonged period of sepsis with multiple organ failure can result in a direct generalized myopathy. This possibility should be kept in mind while treating long term critically ill survivors.

Abstract
The murine leukemia cell lines L1210 and WEHI-3B show a very different sensitivity to the cholera toxin (CT). The in vitro growth of L1210 is completely inhibited by 10(-8) M CT, while WEHI-3B growth shows the same inhibition at 10(-11) M. The analysis of membrane ganglioside pattern of the two cell lines shows that in L1210 cells the major component is the GM1a ganglioside while the monosialogangl oside fraction from WEHI-3B is entirely composed of gangliosides of the 'b' series among which GM1b is the more represented. The total cholera toxin binding capacity of the ganglioside extract from L1210 cells is more than hundred fold higher than that of WEHI-3B and this difference is also confirmed by the number of CT receptors/cell and by the binding of FITC-B subunit of CT on the cells. These surprising data are in conflict with the poor sensitivity to CT evidenced by L1210 compared to WEHI-3B cells. In order to clarify this discrepancy we investigated the cAMP accumulation, the cell viability and the clonogenicity of these two leukemia cell lines following the treatment with CT and forskolin (FRSK). The treatment of WEHI-3B cells with CT induces a dramatic increase of intracellular cAMP which highly correlates with cell death and the decrease of clonogenicity and this result is partially obtained by the treatment with FRSK. L1210 cells do not evidence significant cAMP accumulation neither with CT nor with FRSK treatment. These data suggest that the different inhibiting effect of CT on WEHI-3B and L1210 cells does not correlate with their different pattern of gangliosides and the related toxin binding capacity. Further they indicate that the growth inhibition of WEHI-3B cells is closely related with a cAMP-dependent cell killing mechanism, while the inhibition of L1210 growth (produced by high concentration of CT) is mediated by a cAMP independent mechanism.

Abstract
We investigated the effects of the prone position on the mechanical properties (compliance and resistance) of the total respiratory system, the lung, and the chest wall, and the functional residual capacity (FRC) and gas exchange in 17 normal, anesthetized, and paralyzed patients undergoing elective surgery. We used the esophageal balloon technique together with rapid airway occlusions during constant inspiratory flow to partition the mechanics of the respiratory system into its pulmonary and chest wall components. FRC was measured by the helium dilution technique. Measurements were taken in the supine position and after 20 min in the prone position maintaining the same respiratory pattern (tidal volume 10 mL/kg, respiratory rate 14 breaths/min, FIO2 0.4). We found that the prone position did not significantly affect the respiratory system compliance (80.9 +/- 16.6 vs 75.9 +/- 13.2 mL/cm H2O) or the lung and chest wall compliance. Respiratory resistance slightly increased in the prone position (4.8 +/- 2.5 vs 5.4 +/- 2.7 cm H2O.L-1.s,P < 0.05), mainly due to the chest wall resistance (1.3 +/- 0.6 vs 1.9 +/- 0.8 cm H2O.L-1.s, P < 0.05). Both FRC and PaO2 markedly (P < 0.01) increased from the supine to the prone position (1.9 +/- 0.6 vs 2.9 +/- 0.7 L, P < 0.01, and 160 +/- 37 vs 199 +/- 16 mm Hg, P < 0.01, respectively), whereas PaCO2 was unchanged. In conclusion, the prone position during general anesthesia does not negatively affect respiratory mechanics and improves lung volumes and oxygenation.

Abstract
The ganglioside content and pattern have been followed in the different tracts (rectus, convoluted and uterine) of the frog oviduct during the reproductive cycle. The main variations we observed are: a) average higher levels of ganglioside sialic acid in the preovulatory phase, with two peaks in March and April for the convoluted and rectus tract, respectively, and a more homogenous behaviour for the uterine tract; in all three tracts of the oviduct a minimum coincident with the ovulation has been found; b) a balanced presence of sulfolipids and gangliosides in the uterine tract: in fact sulfolipids, whose variations have been determined in a previous work, are higher when gangliosides are lower and vice versa, maintaining nearly constant the total negative charge due to these glycolipids; c) an alternate fluctuation of monosialo- and disialo-gangliosides in the preovulatory phase and a net trend toward the increase of monosialo- and the decrease of disialogangliosides in the postovulatory phase; trisialo-gangliosides are in general less represented and show less marked variations; d) the presence of particular gangliosides in particular moments of the reproductive cycle: Fuc-GM1, a fucosylated ganglioside, is higher than the more represented GM1 during the ovulation, while GD1 alpha, a ganglioside with a sialic acid residue linked to GalNAc, is steadily present in all three tracts after ovulation.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This paper deals with the definition of intensive care medicine and the organization of different levels of care; intermediate and high level. The organization, facilities and personnel for intermediate care are discussed. The available public data on the organization of intensive medicine and modifications planned by the Legislator are considered. Finally, the usefulness of intermediate care and an estimate of the actual need, based on prospective multicentre ad hoc studies, are discussed.

Abstract
Inhalation anesthetics diminish cerebrovascular resistance, augmenting cerebral blood flow (CBF) and hematic volume. This may lead to a dangerous increase in intracranial pressure (ICP). It has been observed that isoflurane used in hypocapnia does not appear to cause an increase in ICP equal to that caused by other inhalation anesthetics. The authors aimed to evaluate the effects of isoflurane on ICP and on intracranial vessel reactivity to changes in CO2 using a pulsed intracranial Doppler technique which measures cerebral flow velocity (CFV). A prospective study was performed at the Neurosurgery Clinic of the University of Milan in 10 in-patients due to undergo surgical removal of supratentorial intracranial expansion. Patients were anesthetised with isoflurane 1 MAC in air and O2. The following parameters were monitored: ICP at a spinal subarachnoid level; mean arterial pressure (MAP); cerebral perfusion pressure (CPP); ECG; CFV; EtCO2. The study was subdivided into 5 stages: basal (before induction); hypocapnia lasting 30 min; registration of data for 10 min; stabilisation phase in normocapnia; registration in normocapnia. The results show that during hypocapnia isoflurane causes significant reductions in MAP and CCP whereas ICP and CFV tend to diminish but not significantly. On the contrary, isoflurane in normocapnia causes an increase in ICP and a further and more marked reduction in CPP with a corresponding but not significant increase in CFV. In conclusion, in the light of these results the increase in ICP and the contemporary reduction of MAP would appear to restrict the use of isoflurane in normocapnia in patients with intracranial pathologies.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Age-related changes of the ceramide composition of gangliosides were studied in the synaptosomal and myelin fractions from rat brain, carrying plasma membranes of neuronal and glial origin, respectively. The five major gangliosides (GM1, GD1a, GD1b, GT1b, and GQ1b) present in these fractions were separated and quantitated by normal-phase HPLC. Each ganglioside was then fractionated by reverse-phase HPLC into the molecular species carrying a single long-chain base (LCB). The largely preponderant LCBs in the synaptosomal and myelin fractions were the C18:1 and C20:1. The content of C20:1 LCB, generally low at 1 month, increased with age in all analyzed gangliosides and in all subcellular fractions and was greater in the "b series" than in the "a series" gangliosides. Remarkably, GM1 was the only ganglioside where the proportion of LCB 20:1 was higher in the synaptosomal fraction than in the myelin fraction. The fatty acid composition of the C18:1 or C20:1 LCB species of the different gangliosides in the synaptosomal and myelin fractions did not undergo appreciable changes with age. Stearic acid was largely predominant in all the gangliosides of the synaptosomal fraction, more in the C18:1 than in the C20:1 LCB species (80-90% vs. 60-70%). The gangliosides of the myelin fraction were characterized by a lower content of 18:0 and a much higher content of 16:0 and 18:1 fatty acids than those of the synaptosomal fraction. Thus, the ceramide composition is different in the gangliosides of neuronal and myelin origin and appears to be subjected to an age-related control.

Abstract
The interaction of Tetanus toxin with phospholipid vesicles containing gangliosides (GD1a, GD1b or GT1b) or phosphatidic acid has been investigated at neutral or acidic pH. Change in the thermotropic properties of the vesicles occurred only after addition of the toxin at acidic pH, and led to surface binding or membrane insertion of the protein, dependent on the physical state of the membrane. Most remarkably, toxin addition at acidic pH to dipalmitoyl-phosphatidylcholine vesicles containing GT1b ganglioside, caused formation of ganglioside microdomains on the vesicle surface.

Abstract
The ability of Fuc-GM1 ganglioside to mimic the receptor function of GM1 for cholera toxin (CT) has been investigated. For this purpose, rat glioma C6 cultured cells were enriched with Fuc-GM1 and the responsiveness to CT was compared with that of cells enriched with GM1 ganglioside. Fuc-GM1 was taken up by cells as rapidly and to the same extent as GM1. When comparable amounts of ganglioside were associated, the cells enriched with Fuc-GM1 bound the same amount of 125I-CT as did cells enriched with GM1. Under conditions in which GM1- and Fuc-GM1-enriched cells bound comparable amounts of CT, the Fuc-GM1-treated cells accumulated virtually the same amount of cyclic AMP as did GM1-treated cells, and activation of adenylate cyclase was also similar. The lag time preceding the CT-induced cAMP accumulation was the same in Fuc-GM1- and GM1-enriched cells. High-sensitivity isothermal titration calorimetry (ITC) experiments showed that the association constants of CT with Fuc-GM1 or GM1 ganglioside were comparable (4 x 10(7) M-1 and 1.9 x 10(7) M-1, respectively, at 25 degrees C). Also, the association constants of the B-subunit pentamer with Fuc-GM1 or GM1 ganglioside were comparable (about 3 x 10(7) M-1 and 7 x 10(7) M-1, respectively, at 25 degrees C).

Abstract
GD1a is the major ganglioside of rabbit brain microsomal membranes and occurs mainly with two molecular species, containing the C18:1 (62.3%) and C20:1 (37.7%) long-chain bases. The membranes were exposed to Vibrio cholerae (VC) sialidase under conditions where the enzyme hydrolyzed only GD1a (approximately 9%), producing GM1 ganglioside, whereas the other gangliosides remained virtually unaffected. The long-chain-base analysis showed that newly-formed GM1 contained approximately 68% of the C20:1 molecular species. This indicates that VC sialidase did not randomly affect the two molecular species of GD1a but hydrolyzed preferentially the C20:1 one. In similar experiments, GD1a was inserted into the external layer of phosphatidylcholine vesicles and incubated with VC sialidase under conditions producing approximately 10% hydrolysis. Long-chain-base analysis showed that the proportion of C20:1 species in GM1 was 25.1% using vesicles composed of dipalmitoylphosphatidylcholine and 42.3% with egg phosphatidylcholine, whereas it was 39.2% in the starting GD1a. Therefore, in artificial membranes, VC sialidase acted preferentially on the C18:1 or C20:1 molecular species, depending on the length and unsaturation of the phospholipid fatty acids. Because VC sialidase is known to affect molecular dispersions more easily than packed aggregations of the gangliosidic substrate, the data suggest that in rabbit brain microsomal membranes the GD1a ganglioside molecular species carrying C20:1 long-chain base are more molecularly dispersed than those containing C18:1 long-chain base.

Abstract
The antigen designated as Chol-1 beta, detected by an antiserum specific for cholinergic neurons, has been purified to homogeneity from ganglioside mixtures extracted from Torpedo electric organ and pig brain. The final products from the two sources behaved identically in a wide range of tests and gave coincident immunopositive and Ehrlich-positive spots after thin layer chromatography in seven different solvent systems; they were thus considered to be identical and to constitute a single, pure chemical species. Gas-chromatographic analysis revealed the presence of long-chain bases, glucose, galactose, N-acetylgalactosamine, and sialic acid in integral molar ratios of 1:1:2:1:3; the compound's reactivity to cholera toxin after Vibrio cholerae sialidase treatment on thin layer chromatography and the recovery of GM1 as sole product of exhaustive sialidase treatment identified it as a member of the gangliotetrahexosyl series. From the products of partial enzymatic desialylation and treatment with beta-galactosidase and a comparison of the compound's immunoreactivity to anti-Chol-1 antisera with that of other trisialogangliosides of defined molecular structure, we were able to assign a disialosyl residue alpha-Neu5Ac-(2----8)-alpha-Neu5Ac-(2----3)- to the inner galactose, and we suggest GalNAc as a possible site of linkage of the third sialic acid.

Abstract
24 of 184 patients with vertebro-medullary trauma admitted to the Neurosurgery Clinic of Milan University in the years 1976-1988 have been examined. A common feature of these was a myelic lesion (transverse, complete or incomplete) at cervical level in which respiratory problems had made a period of intensive care indispensable. The purpose of the research was to assess the reliability of certain parameters in establishing patient prognosis. The following parameters were compared: clinical, objective and instrumental examination for a strictly neurological evaluation and for an evaluation of general condition, quantification of the same clinical examination through two scales, the Sunnybrook Cord Injury Scale (SCIS) for the neurological factor and the APACHE II for general condition, the type of treatment, with the same basic medical-resuscitation treatment. The result of the surgery or non-surgery was considered a posteriori. It is concluded that, in the case of the patients considered (high myelic lesion) the prognosis must be split into two different moments that the patient goes through in succession: the acute phase and the stabilisation phase. In the first phase, in which the vital functions are involved, the SCIS and APACHE II scales (with their sum) have great prognostic value; in the second phase, certain values, already considered on the APACHE II scale, are comparable in all patients and the prognostic problem is based on the other scale (SCIS) and on the adjuvant neurophysiological techniques. The very distinction between the two different phases that the patient traverses appears important also for the purposes of surgical indication.2
