N Engl J Med ; In adults with suspected meningitis clinicians routinely order computed tomography CT of the head before performing a lumbar puncture, akute Thrombophlebitis Clinic. Full Text of Background We prospectively studied adults with suspected meningitis to determine whether clinical characteristics that were present before CT of the head was performed could be used to identify patients who were akute Thrombophlebitis Clinic to have abnormalities on CT.

Full Text of Methods Of the patients with suspected meningitis, 78 percent underwent CT of the head before undergoing lumbar puncture. In 56 of the patients 24 percent akute Thrombophlebitis Clinic, the results of CT were abnormal; 11 patients 5 percent had akute Thrombophlebitis Clinic of a mass effect.

The clinical features at base line that were associated with an abnormal finding on CT of the head were an age of at least 60 years, immunocompromise, a history of central nervous system disease, and a history of seizure within one week before presentation, as well as the following neurologic abnormalities: Akute Thrombophlebitis Clinic of these features were present at base line in 96 of the patients who underwent CT scanning of the head 41 percent.

The CT scan was normal in 93 of these 96 patients, yielding a negative predictive value of 97 percent. Of the three misclassified patients, only one had a mild mass effect on CT, and all three subsequently underwent lumbar puncture, with no evidence of brain herniation one week later. Full Text of Results In adults with suspected meningitis, clinical features can be used to identify those who are unlikely to have abnormal findings on CT of the head, akute Thrombophlebitis Clinic.

Full Text of Conclusions Community-acquired bacterial akute Thrombophlebitis Clinic is a medical emergency; early diagnosis and therapy reduce morbidity and mortality. Adults defined as persons older than 16 years of age with clinically suspected meningitis who were seen in the emergency department of Yale—New Haven Hospital from July to June were eligible for enrollment whether or not they underwent CT of the head before undergoing lumbar puncture.

After screening patients, we excluded for the following reasons: A total of were therefore enrolled in the study. Informed consent was obtained from all enrolled patients in accordance with the guidelines of the Human Investigation Committee at Yale University School of Medicine.

The patients' base-line characteristics were recorded in the emergency department before CT of the head and lumbar puncture were performed.

Information was collected on sociodemographic characteristics; coexisting conditions measured with use of the Charlson comorbidity index 9 ; the presence or absence of immunocompromise, clinical features, and various neurologic abnormalities 10,11 ; laboratory results; and management decisions.

The information was obtained by a clinician in the emergency department or by a study investigator. Information regarding clinical status was available one week after study entry in the case of patients.

CT was performed with the use of a GE Hilight Advantage scanner GE Medical Systems, Milwaukeeand the results were interpreted by staff neuroradiologists who had no knowledge of the patients' clinical findings, akute Thrombophlebitis Clinic. An independent neuroradiologist reviewed all CT scans. The two neuroradiologists were in agreement in the case of all but three scans; disagreements were resolved by a third neuroradiologist.

The CT results were categorized as normal or showing atrophy onlyas showing a focal abnormality with or without a mass effect, or as showing a nonfocal abnormality with akute Thrombophlebitis Clinic without a mass effect.

A mass effect was categorized on the basis of the degree of effacement of sulci, cisterns, and ventricles, as mild effacement of less than 50 percentmoderate effacement of 50 percent or moreakute Thrombophlebitis Clinic, or severe effacement of 50 percent or more plus a midline shift.

After akute Thrombophlebitis Clinic analyses had been conducted, we conducted univariate regression analyses of base-line clinical features with respect to the target outcome abnormal findings on CT. Clinically plausible base-line variables that were significantly associated with abnormal findings on CT were used to identify a subgroup of patients with a low likelihood of such abnormal findings, akute Thrombophlebitis Clinic.

The chi-square test, akute Thrombophlebitis Clinic, Fisher's exact test, Student's t-test, and the Wilcoxon test were used. All reported P values are two-sided.

The base-line characteristics of the adults with suspected meningitis are shown in Table 1 Table 1 Characteristics of the Patients with Suspected Meningitis. The cohort consisted primarily of young adults median age, 40 yearsbut 16 percent Varizen und Sanddornöl of were at least 60 years of age; 52 percent were white.

Coexisting conditions were present in 81 patients 27 akute Thrombophlebitis Clinic25 patients 8 percent had a history of central nervous system disease, and 75 patients 25 percent were immunocompromised; infection with the human immunodeficiency virus HIV was the most common cause of immunocompromise.

Most patients presented with headache 79 percent and fever 67 percent. A total of patients 50 percent had photophobia, 46 percent described a stiff neck, and 21 7 percent had had a seizure within one week before presentation. Most patients 91 percent had a normal level of consciousness as defined by a score of 14 or 15 on the Glasgow Coma Scale.

A minority of patients 50 ofor 17 percent had a focal abnormality on neurologic examination with use of the Modified NIH Stroke Scale, akute Thrombophlebitis Clinic percent had Akute Thrombophlebitis Clinic sign or Brudzinski's sign, and 1 patient had papilledema. The patient with papilledema had HIV-associated cerebral toxoplasmosis; CT revealed a severe mass effect, and the patient died of brain herniation without undergoing lumbar puncture.

A median of 7 minutes range, 1 to 30 was necessary for the enrolling physician to perform the neurologic examination using the Modified NIH Stroke Scale. Laboratory evaluation revealed that 80 patients 27 percent had objective evidence of meningitis defined by the presence of more than 5 white cells per milliliter of cerebrospinal fluid18 patients 6 percent had a pathogen identified on the basis of cerebrospinal fluid analysis, and 20 patients 7 percent had a positive blood culture.

Decisions made by physicians in the emergency department and the clinical status of patients one week after study entry are shown in Table 2 Table 2 Physicians' Decisions in the Emergency Department and the Clinical Outcome of Adults with Suspected Meningitis.

Most patients 52 percent were hospitalized, and patients 41 percent received empirical antibiotic therapy for meningitis, akute Thrombophlebitis Clinic. A total of patients 83 percent were evaluated by postgraduate residents, and 52 17 percent were evaluated by attending physicians.

Among the physicians who were surveyed, 59 akute Thrombophlebitis Clinic stated that their primary reason for ordering a CT scan of the head was their suspicion that a focal brain abnormality was present, 68 34 percent ordered the scan because they viewed it as the standard of care, and 10 5 percent stated that fear of litigation was their primary reason for ordering the scan; 4 ordered scans for a combination of reasons.

Of the 56 patients 24 percent with abnormal results, 29 12 percent had a focal akute Thrombophlebitis Clinic without a mass effect, 12 5 percent had a nonfocal abnormality without a mass effect, and 4 2 percent had a combination of focal and nonfocal abnormalities without a mass effect, akute Thrombophlebitis Clinic. Only 11 patients 5 percent had evidence of a mass effect on CT of the head: Of the five patients who had meningitis due to a documented bacterial cause, only two underwent CT of the head; one patient had normal results, akute Thrombophlebitis Clinic, and the other had nonfocal abnormalities without a mass effect, akute Thrombophlebitis Clinic.

The mean time from admission to the emergency department to lumbar puncture was 5. One week after lumbar puncture, the clinical status of patients was normal, 51 patients had a persistent headache, and 6 patients 2 percent had a residual neurologic deficit Table 2. Four patients 1 percent died, akute Thrombophlebitis Clinic. The clinical status of eight patients was not known. Base-line features that were not associated with a significant risk of abnormal findings on CT included race or ethnic group, insurance status, akute Thrombophlebitis Clinic, presence or absence of a history of parameningeal disease i.

The base-line clinical characteristics that were associated with an increased likelihood of abnormal findings on CT of the head were used to identify a subgroup of patients with a decreased likelihood of having abnormal findings on CT. Among these 96 patients, the results of CT were normal in 93 97 percent and abnormal in 3 3 percent 2 patients had no mass effect — 1 had a focal and 1 had a nonfocal abnormality — and 1 had hydrocephalus and a mild mass effect.

Therefore, only 1 of the 96 patients had a CT scan that revealed a mass effect; the 10 other patients with a mass effect on CT were identified on the basis of the presence of one or more of the significant clinical features at base line, akute Thrombophlebitis Clinic.

Among the patients with suspected meningitis who underwent CT, 4 patients 2 percent — 3 with a severe mass effect and 1 with a mild mass effect — had abnormal findings that caused the clinician to avoid lumbar puncture. All four patients had one or more of the significant clinical characteristics at base line.

Two of the patients with a severe mass effect died of brain herniation within one week after undergoing CT despite the fact that they had never undergone lumbar puncture. Of patients in whom lumbar puncture was performed and for whom follow-up data were available one week later including 5 patients with a mild mass effect wie Krampfadern Erweiterung behandeln 2 patients with a moderate mass effect on CT of the headnone had herniation.

A diagnosis of meningitis requires a lumbar puncture to confirm the presence of inflammatory cells in the cerebrospinal fluid, to identify the infecting pathogen, and to guide antimicrobial therapy.

In this study of adults with suspected meningitis, the majority 78 percent underwent CT of the head before they had a lumbar puncture. Specific base-line characteristics could be used to identify a subgroup of patients who were unlikely to have abnormalities on CT of the head. Among the 56 patients with abnormal findings on CT, 4 patients had a mass effect that prompted clinicians to avoid lumbar puncture, and 2 of these 4 patients subsequently had brain herniation.

The remaining 52 patients with abnormal results on CT underwent lumbar puncture, and one week later, none had had brain herniation. Although the clinical presentation of our cohort was typical of that of adults with suspected meningitis, the cohort had several noteworthy features.

The median age was 40 years, but 16 percent of patients were at least 60 years of age and 25 percent were immunocompromised. Although most patients had a normal level of consciousness, 17 percent had a focal abnormality on a neurologic examination that used the Modified NIH Stroke Scale. Although meningitis was the primary reason for lumbar puncture in all patients, only 27 percent had documented evidence of meningitis i, akute Thrombophlebitis Clinic.

Our policy of including all adults with suspected meningitis allowed us akute Thrombophlebitis Clinic make two important observations. First, the percentage of adults with suspected meningitis who underwent CT of the head before undergoing lumbar puncture in the emergency department was high 78 percent.

Second, the mean time from admission to the emergency department to lumbar puncture was significantly longer for patients who first underwent CT than for patients who did not first undergo CT 5. There was also a trend toward a longer time from admission to the initiation of empirical antibiotic therapy for patients who underwent CT before undergoing lumbar puncture.

The absence of a significant difference in this interval between the two groups may be accounted for by the common practice of initiating antibiotic therapy before performing lumbar puncture in patients with suspected meningitis.

Nonetheless, the significant delay in lumbar puncture caused by CT can affect other management decisions e. In most cases 76 percentthe results of CT of the head were normal. Of the 56 patients with abnormal results, only 11 had abnormalities associated with a mass effect, and only 4 2 percent of the patients who underwent CT had abnormalities that caused the clinician to avoid lumbar puncture.

Our study has several advantages over previous studies. Second, the base-line characteristics that we identified as being associated with an increased likelihood of abnormal findings on CT of the head are clinically plausible and easy to assess in the emergency department, akute Thrombophlebitis Clinic.

Third, the neurologic findings that we identified as being associated with an increased risk of abnormalities on CT were assessed with use of the Modified NIH Stroke Scale, which has a high rate of interobserver agreement. In identifying a subgroup of patients with a decreased likelihood of having abnormal findings on CT of the head, akute Thrombophlebitis Clinic, we used all 13 significant base-line characteristics for two reasons.

First, we wanted to include the clinical features that practicing physicians would consider to be associated with an abnormal finding on CT of the head in patients with suspected meningitis. Second, since the ultimate goal is to reduce the number of unnecessary CT scans, we wished to identify a combination of features that had a high negative akute Thrombophlebitis Clinic value.

As shown in Table 5the absence of the significant clinical features at base line had a negative predictive value of 97 percent. Of the three patients who were misclassified with the use of these characteristics, akute Thrombophlebitis Clinic, only one patient had a mild mass effect, and all three patients underwent lumbar puncture without subsequent brain herniation.

Our study has limitations. Because it was conducted at a single institution, our findings will require validation in an independent cohort with different demographic features in other geographic areas, akute Thrombophlebitis Clinic. Although the negative predictive value of our approach was not percent, the three patients who were misclassified akute Thrombophlebitis Clinic lumbar puncture without subsequent brain herniation.

Furthermore, this approach identified all three of the patients with a severe mass effect on CT two of whom subsequently had brain herniation in the absence of lumbar puncture. Our findings indicate that adults with suspected meningitis who have none of the significant base-line features that we identified are good candidates for immediate lumbar puncture, since they have a low risk of brain herniation as a result of lumbar puncture, akute Thrombophlebitis Clinic.

The use of this approach in our cohort would have decreased the frequency of CT by 41 percent. Patients who have any of the base-line clinical features we identified should undergo CT after blood has been drawn for culture and empirical antibiotic therapy has been initiated.

Our findings should inspire confidence on the part of clinicians that the risk of lumbar puncture is negligible in such patients, even in those with a mild or moderate mass effect on CT of the head. Future studies will be needed to validate our results in other geographic areas, to determine their value with respect to reducing medical and legal concerns among physicians, and to assess their ability to reduce unnecessary costs and delays in the diagnosis and treatment of meningitis.

Akute Thrombophlebitis Clinic

Gesunde Venen sind für den menschlichen Blutkreislauf unverzichtbar. Die Venen sind dafür verantwortlich, akute Thrombophlebitis Clinic, "verbrauchtes", Stocking von Krampfadern für Männer Akute Thrombophlebitis Clinic aus dem Körper Organen, Muskeln, Haut zum Herzen zurück zu transportieren.

Die Beinvenen leisten dabei die schwierigste Arbeit, denn sie müssen das Blut entgegen der Schwerkraft nach oben transportieren, akute Thrombophlebitis Clinic. Aufgrund dieser Belastung erkranken sie leichter. Der Antrieb für die Beinvenen kommt aus den Beinmuskeln.

Aktive Muskeln sorgen für einen gesunden Blutfluss - und umgekehrt. Es gibt am Bein drei Venensysteme: Bei Normal- und Übergewichtigen sind sie unsichtbar, daher werden Erkrankungen jahrzehntelang übersehen. Die Hautvenenakute Thrombophlebitis Clinic, sie sind als einzige oberflächlich und somit sichtbar. Hier erkennt man z. Das ist aber immer nur akute Thrombophlebitis Clinic Spitze eines kranken Eisbergs! Ausserdem gibt noch Verbindungsvenen zwischen den Venensystemen.

Venenerkrankungen können angeboren oder im Laufe des Lebens erworben sein. Wir wissen, wie das geht. Lernen Sie hier und im Gespräch mit mir und meinen Expertenteams, wie Sie Venenerkrankungen vermeiden oder ausheilen können! Wie genau möchten Sie es wissen?

Jede fachärztliche Diagnostik sollte Ihnen sagen können, ob Sie eine Venenschwäche haben oder nicht. Glauben Sie keiner Untersuchung, die kürzer als 15 Minuten dauert! Die Hilfe beginnte dann mit dem Therpieangebot. Der Facharzt wird Ihnen das empfehlen, was er selber schon lange kennt, und das ist gut gemeint, aber meist das Althergebrachte. Sie wollen aber keine unnötige Operation, keine Hannover kaufen Varikosette, keinen Venenverlust.

Sie wollen auch keine Experimente. Sie wollen eine Therapie, die Krampfadern und Besenreiser schmerzfrei und zuverlässig entferntdie die Venenschwäche stoppt und die auch vorbeugt. Wir wollen wissen, wie es zu Ihrer Venensituation gekommen ist. Also finden wir es heraus - mit HR-Sonographie.

Etwa 25 Prozent der Frauen und 21 Prozent der Männer über 35 Jahre sind venenkrank — viele davon wissen es nicht". Heute müssen wir sagen: Die Frage ist nur, wie schnell und wie schlimm es uns erwischt. Venenerkrankungen sind heimtückisch, weil sich niemand darum kümmert, bis irgendetwas ungewöhnlich aussieht oder die ersten Beschwerden beginnen.

Liebe Leute, wie dumm ist das denn!? Ihr habt doch vom Zahnarzt gelernt dass man nicht wartet bis ein Zahn braun wird oder wehtut! Ich entschuldige mich im Namen aller Venenärzte, wir haben es Euch nicht besser vermittelt.

Wenn wir auf Stühlen sitzen oder still stehen, steht auch das Venenblut. Es beginnt, sich an Venenwände und Venenklappen zu binden, und es Kalanchoe von Krampfadern kleinste Entzündungsreize.

Bewegen wir uns wieder, lösen sich diese Mikrothrombosen wieder auf. Je öfter und je länger es zu Mikroentzündungen kommt, desto eher werden Venenwände und besonders die zarten Venenklappen gereizt und schliesslich langsam aber sicher umgebaut dicker, akute Thrombophlebitis Clinic, plumper, träger Ich nenne das den Beginn einer Venenschwäche. Ja, glauben Sie, akute Thrombophlebitis Clinic, dass ein normaler Venenarzt dies richtig diagnostizieren kann? Es sei denn, Sie erscheinen nach einem langen Arbeitstag um Durch die Muskelbewegungen z.

Es ist eher ein Ignoranz- Wie wird man von Krampfadern in den Männern los Verhaltensproblem. Ohne Bewegung fehlt die Venenpumpe, und das Blut staut sich und weitet die Venen immer mehr.

Irgendwann sind sie so überdehnt, dass die Klappen nicht mehr greifen. Zu diesem Zeitpunkt könnte eine Änderung der Gewohnheiten noch alles retten, ohne jeden Eingriff!

Wieso ist ein intaktes Venensystem für den gesamten Körper so wichtig? Das Venensystem ist im Körperkreislauf sozusagen die Recycling-Abteilung. Venenblut ist sauerstoff- und nährstoffarmdafür schlackenreich. Es muss rasch zurück zu Herz, Lunge akute Thrombophlebitis Clinic Leber. Funktioniert eine Vene nicht, sammelt sich verbrauchtes Blut mit Stoffwechselschlacken an.

Das ist wie bei einem Streik der Müllabfuhr: Der Müll staut sich. Durch Stauung, Druckzunahme und Stoffwechselschäden kommt es allmählich zu Beschwerden: Alle Beschwerden nehmen typischerweise beim längeren Stehen oder Sitzen zu, sind also abends am deutlichsten.

Und wer welche hat, kann sie loswerden und dann für immer vorsorgen. Bei Fragen beraten wir Sie gern! Eine plötzlich auftretende strangartige oder flächige Rötung am Bein kann eine Venenentzündung anzeigen. In der Regel ist das Areal bei Berührung oder Bewegung unangenehm oder gar schmerzhaft.

Betrifft es oberflächliche Venen, nennt man es Venenentzündung Phlebitis, Thrombophlebitis. Die Bezeichnungen sind verwirrend und müssen unbedingt unterschieden werden. Das ist medizinisch bedeutsamer, denn hier sind die Hauptabflusswege des Blutes verschlossen Bein schwillt an, schmerzt insgesamt. Die Grundprinzipien sind beide Krankheitsbilder pathophysiologisch gleich, und aus einer harmlosen Venenentzündung kann unbehandelt auch eine Thrombose entstehen.

Neulich sprach ein Seminarteilnehmer Ärzte! Im Grunde war es ein verbaler Volltreffer, denn jeder Thrombus macht eine -itis Entzündungegal in welcher Vene. Bilder einer akuten Venenentzündung aufgrund einer unbehandelten Venenschwäche — vor und nach der Behandlung.

Akute Thrombophlebitis Clinic dunkle Stelle kennzeichnet einen "Ulcus", einen zeitweilig offenen, nässenden und schwer geschädigten Hautbereich. Nach erfolgreicher Behandlung schlägt der Patient wieder akute Thrombophlebitis Clinic — auf dem Tennisplatz! Bilder einer leichten Venenentzündung Phlebitis: Wie kommt es zu Venenentzündungen? Fast immer betrifft es Venen, die bereits erkrankt sind, ohne dass der Betreffende es wusste. Venen benötigen einen gewissen Durchfluss, um gesund zu bleiben, akute Thrombophlebitis Clinic.

In erkrankten Venen Überlastung, Klappendefekte kommt es zum Stillstand des Flusses, und die Blutbestandteile beginnen nach einer Weile miteinander und mit der Venenwand zu verkleben Thrombusbildung.

Es entsteht eine Entzündung der Venenwand, die sich auf die Umgebung fortsetzt. So kommt es zu den typischen Merkmalen akute Thrombophlebitis Clinic verhärteten, schmerzhaften Vene und einer geröteten Umgebung.

Manchmal kommt eine Schwellung der Region oder des Beines hinzu, akute Thrombophlebitis Clinic. Die entzündete Vene ist in der Regel durch Thromben verschlossen, so dass zu diesem Zeitpunkt kein krankhafter Rückfluss feststellbar ist. Die Ursache des Venenproblems wird daher auch von Ärzten oft übersehen. Im Idealfall stellt sich der vorherige Zustand samt Venenschwäche wieder her kein wirklicher Fortschritt! In beschwerdefreien Phasen möchte der Patient oft nicht an eine Therapie denken, und so wird sie hinausgeschoben.

Eine 43 jährige Dame fliegt von Neuseeland zurück nach Deutschland. Am nächsten Tag bemerkt akute Thrombophlebitis Clinic eine zunehmende Empfindlichkeit von der rechten Kniekehle geradlinig nach unten bis zur Wadenmitte. Am Folgetag ist ein roter Streifen zu sehen und ein Strang zu tasten.
