AbstractIntroductionTransient fluctuation of smell concurrent with phantosmia has not been reported. Four such cases are presented.MethodsCase 1: A 27-year-old left handed (pathological) female, 7 years prior to presentation, noted constant olfactory hallucinations of dried blood and rotten sour eggs, level 8/10 in intensity.Results: Without phantosmia: Alcohol Sniff Test (AST): 14 (hyposmia). Brief Smell Identification Test (BSIT): 10 (normosmia). Retronasal Smell Index: 0 (abnormal).With phantosmia: AST: 1 (anosmia). BSIT: 12 (normosmia). Retronasal Smell Index: 0 (abnormal). Normal 72-hour EEG and MRI.Case 2: A 19 year old right-handed woman presented with a 4 month history of unpleasant, fruity, rotten phantosmia occurring three times a day, 6-7/10 in intensity.Results: Without phantosmia: Pocket Smell Test (PST): 3 (normosmia). AST: 30 (normosmia). With phantosmia: AST: 13 (hyposmia). CT scan: normal. MRI: normal.Case 3: A 40 year old right-handed female presented with ashtray/cigarette phantosmia , occurring 10 times a day, lasting seconds to all day, 10/10 in intensity. Her sense of smell is normal except when the phantosmia is present, during which time it decreases to 70% of normal.Results: Without phantosmia: BSIT: 11 (normosmia). AST: 30 (normosmia). With phantosmia: AST: 11 (hyposmia). PST: 3 (normosmia). EEG: normal. MRI: few subcortical white matter hyperintensities on flair imaging.Case 4: A 60 year old right handed male with type 1 diabetes mellitus presented with four months of phantosmia of sweet tobacco, level 8/10 in severity, involves both nostrils, lasting 10 seconds and occurring two times a day. Over time, the hallucinated odor changed to a soapy smell 2-3/10 in intensity.Results: Without phantosmia: AST: 6 (hyposmia). BSIT: 8 (hyposmia). With phantosmia: AST: 1 (anosmia). PST: 2 (hyposmia). CT scan: normal.DiscussionOlfactory ability should be assessed in those with phantosmia, both during and in the absence of hallucinated odors, to detect transient olfactory deficits in order to direct treatment towards this condition.

Tobacco primary cell wall and normal bacterial Acetobacter xylinum cellulose formation produced a 36.8±3Å triple-stranded left-hand helical microfibril in freeze-dried Pt-C replicas and in negatively stained preparations for TEM. As three submicrofibril strands exit the wall of Axylinum , they twist together to form a left-hand helical microfibril. This process is driven by the left-hand helical structure of the submicrofibril and by cellulose synthesis. That is, as the submicrofibril is elongating at the wall, it is also being left-hand twisted and twisted together with two other submicrofibrils. The submicrofibril appears to have the dimensions of a nine (l-4)-ß-D-glucan parallel chain crystalline unit whose long, 23Å, and short, 19Å, diagonals form major and minor left-handed axial surface ridges every 36Å.The computer generated optical diffraction of this model and its corresponding image have been compared. The submicrofibril model was used to construct a microfibril model. This model and corresponding microfibril images have also been optically diffracted and comparedIn this paper we compare two less complex microfibril models. The first model (Fig. 1a) is constructed with cylindrical submicrofibrils. The second model (Fig. 2a) is also constructed with three submicrofibrils but with a single 23 Å diagonal, projecting from a rounded cross section and left-hand helically twisted, with a 36Å repeat, similar to the original model (45°±10° crossover angle). The submicrofibrils cross the microfibril axis at roughly a 45°±10° angle, the same crossover angle observed in microflbril TEM images. These models were constructed so that the maximum diameter of the submicrofibrils was 23Å and the overall microfibril diameters were similar to Pt-C coated image diameters of ∼50Å and not the actual diameter of 36.5Å. The methods for computing optical diffraction patterns have been published before.

A battery of six tests assessing various aspects of receptive and expressive oral language was administered to 27 cerebral palsied children and controls matched on the variables of age, intelligence, sex, race, hearing acuity, socio-economic status, and similarity of educational background. Results indicated only minimal differences between groups. Signs of deviancy in language behavior often attributed to the cerebral palsied were not observed. Although previous investigators have suggested consistent language disturbances in the cerebral palsied, evidence for a disorder of comprehension and formulation of oral symobls was not found.

We present a case of combined celiac axis and superior mesenteric artery embolism in a 70-year-old patient that was examined in emergency department for atrial fibrillation and diffuse abdominal pain. Standard abdominal x-ray showed air in the portal vein. CT scan with contrast showed air in the lumen of the stomach and small intestine, bowel distension with wall thickening, and a free gallstone in the abdominal cavity. Massive embolism of both celiac axis and superior mesenteric artery was seen after contrast administration. On laparotomy, complete necrosis of the liver, spleen, stomach and small intestine was found. Gallbladder was gangrenous and perforated, and the gallstone had migrated into the abdominal cavity. We found free air that crackled on palpation of the veins of the gastric surface. The patient’s condition was incurable and she died of multiple organ failure a few hours after surgery. Acute visceral thromboembolism should always be excluded first if a combination of atrial fibrillation and abdominal pain exists. Determining the serum levels of d-dimers and lactate, combined with CT scan with contrast administration can, in most cases, confirm the diagnosis and lead to faster surgical intervention. It is crucial to act early on clinical suspicion and not to wait for the development of hard evidence.

Local anesthesia is a safe and less invasive anesthetic management for the endovascular approach to elective aortic aneurysm. We have successfully extended the indication of local anesthesia to a high-risk patient with leaking aneurysm and stable hemodynamics. Patient and methods: A 86 year old patient with renal insufficiency due to longstanding hypertension, coronary artery and chronic obstructive lung disease was transferred to our hospital with a leaking abdominal aortic aneurysm. Stable hemodynamics allowed to perform a fast CT scan, that confirmed the feasibility of endovascular repair. A bifurcated endograft (24mm x 12mm x 153mm) was implanted under local anesthesia. Results: The procedure was completed within 85 minutes without problems. The complete sealing of the aneurysm was confirmed by CT scan on the third postoperative day. Twenty months later, the patient is doing well and radiological control confirmed complete exclusion of the aneurysm. Discussion: The endoluminal treatment is a minimally invasive technique. It's feasibility can be rapidly assessed by CT scan. The transfemoral implantation can be performed under local anesthesia provided that hemodynamics are stable. This anesthetic management seems to be particularly advantageous for leaking abdominal aortic aneurysm since it doesn't change the hemodynamic situation in contrast to general anesthesia. Hemodynamic instability, abdominal distension or tenderness may indicate intraperitoneal rupture and conversion to open graft repair should be performed without delay.
