Three-dimensional accuracy of guided implant placement: indirect assessment of clinical outcomes.

Purpose: Precise preoperative implant planning and its exact intraoperative transfer are crucial for successful implant-supported rehabilitation of partially or completely edentulous patients. In the present pilot study, optical laser scanning was used to evaluate deviations between three-dimensional computer-assisted planned and actual implant positions by indirect methods.

Material And Methods: Five patients receiving a total of 15 implants were included in this study.

A holistic approach to MRSA eradication in critically ill patients with MRSA pneumonia.

Background: The number of Methicillin-resistant Staphylococcus aureus (MRSA) pneumonia cases is increasing in many European countries. In this observational study in one medical and three surgical ICUs multiple interventions for the treatment and eradication of nosocomial MRSA-pneumonia were used.

Patients And Methods: Twenty-one critically ill patients (age: 59 +/- 14 years, 15 males/6 females, 18 ventilator-associated, 3 nosocomial, clinical pulmonary infection score > 6 in all patients, APACHE II 18 +/- 5) were enrolled.

Successful antibiotic treatment of Borreliosis associated pseudolymphomatous systemic infiltrates.

The clinical management of late stage Borreliosis can be difficult due to various associated symptoms and signs and cumbersome microbiological tests. We report a case of successful antibiotic treatment of Borreliosis-associated pseudolymphomatous infiltrates in bone marrow and lymph nodes, which were diagnosed by bone marrow trephine biopsy and positron emission tomography.

Microsporidiosis in travel-associated chronic diarrhea in immune-competent patients.

We analyzed retrospectively 21 immune-competent travelers with chronic traveler's diarrhea (3-6 weeks) after returning from recreational travel to the tropics with stool samples positive for microsporidia. Nine patients had been treated with albendazole and 12 patients had been treated symptomatically. Diarrhea resolved in 8 of 9 and 12 of 12 patients, respectively.

[Hemorrheology and quality of life in fibrinogen- and lipid-lowering therapy].

Previous studies have demonstrated that heparin-induced extracorporeal LDL precipitation is able to reduce total cholesterol, LDL, triglycerides and plasma fibrinogen at the same time and thus improve the hemorheologic pattern. A combination of H.E.

Multi-infarct dementia.

Clinicians have long recognized that dementia is a common symptom among the elderly. The diagnosis of dementia requires us to document the individual's current level of mental functioning and some higher level of intellectual function in the past. The recognition of early or mild cases is specially difficult.

White matter signal abnormalities in normal individuals: correlation with carotid ultrasonography, cerebral blood flow measurements, and cerebrovascular risk factors.

We studied 52 asymptomatic subjects using magnetic resonance imaging, and we compared age-matched groups (51-70 years old) with and without white matter lesions with respect to carotid ultrasonography, cerebral blood flow (xenon-133 injection), and cerebrovascular risk factors. In the group with white matter signal abnormalities, we noted a higher frequency of extracranial carotid artery disease, a lower mean gray matter blood flow (F1), and a significant reduction (p less than 0.05) in blood flow of the slow-flowing (F2) compartment.

Nuclear magnetic resonance image white matter lesions and risk factors for stroke in normal individuals.

The incidence, average number, and localization of lesions of the white matter detected by the T2-weighted nuclear magnetic resonance images among volunteers without cerebrovascular symptoms have been correlated with the number of risk factors for stroke. Accepted risk factors were arterial hypertension, diabetes mellitus, smoking, hypercholesterolemia, and cardiac disease. The 42 subjects examined were divided into Group A (0-1 risk factor, mean age 59.

[Parkinsonism with a high vascular risk--Lechner-Ott syndrome].

A syndrome described as Parkinsonism with high hemodynamic risk was represented. The clinical symptomatology was characterized by late onset, high incidence of diabetes mellitus, increased blood viscosity, enhanced platelet aggregation spontaneously as well as induced by adenosine diphosphate (ADP). The EEG shows reduction of alpha frequency and appearance of slow waves in the theta range located in the temporal region.

[Chronic tuberculous meningoencephalitis as a cause of cerebrovascular insufficiency--a differential diagnostic problem].

The often complicated diagnosis in the reason of uncertain primary clinical symptoms, in a chronical prolonged tuberculous meningoencephalitis, in correlation with the demonstration of an exemplary case, in the present study is reported. In addition, in this case the morphological and clinical signs are very uncommon also in cause of uncharacteristically and misleadingly clinical symptoms. The findings in computed tomography and finally also the rarely autopsy findings, like tuberculous ventriculitis and vasculitis are presented.

Sleep-inducing effect of L-tryptophane.

Night sleep recordings were performed in 10 patients with sleep disturbance in falling asleep as well as in maintaining sleep using a mobile 4-channel EEG registration system. Three consecutive nights, which were spent under different conditions, were evaluated automatically. The first night without treatment was used as a baseline night to objectify the disturbed sleep, the second night was measured following an infusion of a physiological saline solution and prior to the third recording 5 g l-tryptophane were applied to the patients.

[Fatal eosinophilic meningoencephalitis following lacquer poisoning. Case report and differential diagnostic considerations].

The authors report about a 43-year-old male patient, who suffered from an acute toxic brain injury. Twelve days prior to death, after sealing his floor, he experienced progressively increasing headache without fever; the CSF examination disclosed marked eosinophilia. The clinical and pathomorphological features of his illness are discussed and together with the various possible etiologies of eosinophilia in the CSF.

[EEG in multi-infarcts with and without intellectual deterioration].

The character and extent of changes in EEG in 124 patients with multiple infarctions, verified by CT, were reported. Further, the EEG diagnoses of patients with (55) or without (50) accompanying dementia were compared. In 19 patients the evidence of dementia could not be defined clearly.

Rheological aspects of cerebrovascular disease.

Disturbances of the flow properties of the blood may occur in more than 40% of patients with CVD. Abnormal rheologic conditions can be measured as increased blood viscosity and may be caused by corpuscular as well as by plasmatic factors.

Therapeutical aspects of cerebrovascular disease.

Treatment of hemorheologic alterations in patients with CVD must be directed to reduce enhanced platelet and red cell aggregation, to improve reduced red cell deformability, and to control plasmatic hypercoagulability.

CNS cysticercosis--a problem of differential diagnosis.

Although a well-known disease worldwide, cerebral cysticercosis in European countries is a rare event. Due to increased travel to East-Asian and Latin American countries it is possible that the occurrence of brain cysticercosis will become more frequent. These facts should remind us of the possibility of cysticercosis of the nervous system.

[Epidemiology, clinical aspects and long term prognosis of vascular (multiple infarct) dementia].

The frequency of dementia states in old age has been demonstrated and the increasing social medical importance has been focused upon. The discrepant frequency of dementia of cerebrovascular origin between the autopsy and clinical case material and the distinguishing characteristics to the primary degenerative (Alzheimer type) dementia as the most frequent form of dementia have been mentioned. The importance of clinical assessment, apparatus diagnosis and laboratory for the differential diagnosis have been discussed.

[Post-traumatic epilepsy. Clinical, neurophysiological and computer-tomographical aspects].

In 55 patients with posttraumatic epilepsy there was evidence of pathologic computertomographic findings in 76.4% and of pathologic EEG findings in 83.6% of the patients.
