PURPOSE: To evaluate dysphagia objectively and quantitatively, and ta clarify the effect of neck position and viscosity changes in patients with aspiration and laryngeal penetration. MATERIALS AND METHODS: We studied 35 patients with dysphagia and 21 normal controls using videofluoroscopy and scintigraphy. Videofluoroscopy was performed with barium with three different viscosity, and scintigraphy was done, with water, yogurt, and steamed egg mixed with Tc-99m tin colloid. 1f aspiration was found during videofluoroscopic examination, patients neck position was changed and study repeated. Videofluoroscopy was analyzed qualitatively. We calculated 7 quantitative parameters from scintigraphy. According to the videofluoroscopic findings, we divided patients into 3 subgroups; aspiration, laryngeal penetration, and no-aspiration group. RESULTS: The result of videofluoroscopy revealed that the most cornmon finding was the delay in triggering pharyngeal swallow. Pharyrigeal transit time (PTT) and pharyngeal swallowing efficiency(PSE) in patients with aspiration were significantly different from other groups. After neck position change, aspiration could be reduced in all of 7 patients, and laryngeal penetration reduced hy about 82%. PTT ancl PSE were also improved after position change. Aspiration and laryngeal penetration occurred more frequently in thin liquid swallowing than in thick liquid and solid swallowing. CONCLUSION: PTT and PSE were useful for the evaluation of dysphagia. Aspiration and laryngeal penetration could be reduced when appropriate position assumed, We could decrease the chance of aspiration by changing the patient diet consisIency. Scintigraphy might be useful tool to quantitate and follow up these changes.

The oropharyngeal swallow of 26 patients with dysphagia was studied quantitatively and qualitatively using videofluoroscope. Videofluoroscopic examination was done with head in neutral position, and with three different c onsistency of test meals; thin liquid, thick liquid, and solid, When aspiration or laryngeal penetration was noted in neutral position, the study was repeated with different head positions, We compared them with each other and with 25 normal subject(previously presented). 11/26(42%) patients revealed laryngeal penetration or aspiration at least with one consistency of test meal. Aspiration occurred more frequently in thin liquid than thick liquid or solid, Head position change successfully eliminated aspiration in 10/10 patients(100%). Other one patient could not change his head position. 9 numerical parameters were derived and calculated for quantitative examination, Liquid meal oral discharge time, pharyngeal delay time, and pharyngeal transit time were significantly increased in patients with aspiration than in patients without aspiration. Also significantly increased than those of normal controls. Because different test meal consistency gave different values, direct comparison of values regardless of meal consistency was fruitless. And because all the process of swallowing cannot be expressed as numerical parameters qualitative examination of videofluoroscopic result was essential. In conclusion, liquid meal oral discharge time, pharyngeal delay time, and pharyngeal transit time were useful parameters in differentiating and quantifying dysphagia. Aspiration can be reduced when appropriate position assumed. Calculated values were different a according to the consistency of the test meal. Quantitative analysis was helpful, but qualitative examination of videofluoroscopy was essential.

We report a case of cerebral lymphomatoid granulomatosis in a 50-year-old man. Lymphomatoid granulomatosis is an unusual condition which usually presents as a pulmonary manifestation, which occasionally affects the brain, and causes focal inflammatory lesions. Primary cerebral lymphomatoid granulomatosis is very rare. We describe a case of lymphomatoid granulomatosis in the left frontal lobe without pulmonary involvement.

We present a study on the systemic insults in the early death(within one week) after head injury. The patient population consisted of 192 patients who were admitted to the Soonchunhyang University Chonan Hospital from August 1986 to May 1990 after head injury. We collected clinical features and systemic insults including blood pressure, arterial pH, PaO2, PaCO2, hematocrit, and serum concentration of Na, retrospectively. The most common cause of injury was road traffic accident(77.6%). More than half(57.8%) were under the age of 40 years. The interval from injury to admission was within one hour in 63.2%, and within four hours in 91.4%. The mean interval was 1.8 hours. However, in 154(80.2%) patients, we found the evidence of systemic insults on admission. We found hypotension(ststolic less than 90mmHg) in 22.9%, acidemia(pH<7.35) in 71.3%, arterial hypoxemia(PaO2<60mmHg) in 42.7%, hypercarbia(PaCO2>45mmHg) in 28.7%, anemia(hematocrit<30%) in 13.0%, hyponatremia(Na<135mEq/L) in 10.7%, and hypernatremia(Na>145mEq/L) in 11.2%. These results imply that the prehospital emergency care system useful at the scene of accident and during the transportation is more important than the simple quick-transport-system.

We report a case of gastro-colic fistula caused by ectopic gastric mucosa developed at transverse colon. Fistula was detected by colonofiberscopy. And fistulous tract was proved by barium enema. Meckel's diverticulum scan finding was similar to that of GI bleeding; e.g. injected radioactivity was secreted into the lumen and moved along the lumen. There was no bleeding. And there was no diverticulum in the colon. Absence of diverticular pouch may explain this unusuaal GI bleeding-like scan finding rather than focal collection of radioactivity, which is typical of ectopic gastric mucosa found in the Meckel's diverticulum. Ectopic gastric mucosa was confirmed by colonfiberscopic biopsy. We suggest GI bleeding-like pictures should be included differential diagnosis of Tc-99m-O4 (ectopic gastric mucosa or Meckel's diverticulum) scan.

PURPOSE: Piccolo et al. advocated the usefulness of Tc-99m-MDP breast scan in differential diagnosis of breast mass with high accuracy. But there are little or no follow-up studies about it as we know. We studied Tc-99m-MDP uptake pattern and lesions/background ratio in patients complaining palpable breast lesions to evaluate the clinical usefulness of Tc-99m-MDP scan. MATERIALS AND METHODS: Total 34 patients were studied with physical examination, mammogram and Tc-99m-MDP scan prospectively. Anteroposterior and both lateral view of breast were obtained 5 minutes after iv injection of 740 MBq Tc-99m-MDP. Breast uptake pattern of Tc-99m-MDP was analyzed by a grade system: 0=no uptake, grade 1=bilateral diffuse uptake, grade 2=asymmetric faint uptake, grade 3=focal hot uptake. 20 cases were pathologically confirmed by excision biopsy or aspiration biopsy. 14 cases were normal in physical examination and mammo-grain. RESULTS: Pathologic results showed 7 carcinomas, 6 benign solid tumors, and 7 fibrocystic changes. Grade 3 pattern of Tc-99m-MDP uptake was noted in 4/7 carcinomas, 3/6 benign solid tumors, and 1/7 fibrocystic changes. Grade 2 pattern was 2/7, 0/7, 3/7 respectively. The average L/B ratio was 1.66 in carcinomas, 1.68 in benign solid masses, 1.20 in fibrocystic diseases, 1.05 in normal patients. L/B ratio was higher in carcinoma and benign mass groups than in fibrocystic change and normal control groups(p=0.005). But there was no statistical difference between L/B ratio of malignant mass group and benign mass group. CONCLUSION: Tc-99m-MDP scan is not suitable to routine clinical use for breast mass diagnosis. It might be used in limited conditions when whole body bone scan is planned.

Recurrent alternating stroke, i.e., one time ischemic and the other hemorrhagic or vice versa, is an uncommon event. We report a series of eight patients who had recurrent alternating strokes, which were diagnosed by CT scans during the last four years. Infarcts preceded hemorrhage in six patients. In the remaining two patients, hemorrhage developed first and infarct followed. All ischemic strokes were the lacunar infarcts. The lesions of the two attacks were located in different sites in all cases except one. The mean age of the patients was 56.6 years at the time of the first attack and 57.5 years at the time of the second. The mean interval between attacks was 11.8 months. All patients were hypertensive on admission. After the first attack, the outcome was favorable in all patients. However, after the second attack the outcome deteriorated to moderate disability in three, severe disability in one and death in four. We discuss some possible reasons for the rarity of recurrent alternating stroke.

Journal of Korean Medical Science 1992;7(1):52-57
A retrospective study of 90 cases of small-sized (less than 3 mm on the printed CT film) acute (within 24 hours) subdural hematoma (SASDH) is presented. From March 1985 to December 1986, the SASDH were immediately operated on (operation rate: 86.0%). From January 1988 to December 1989, we attempted to treat them conservatively (operation rate: 49.1%). The patient population for this study consisted of 38 surgically-treated patients in the first period (Group I), 26 surgically-treated patients in the second period (Group IIs), and 26 conservatively-treated patients in the second period (Group IIc). We compared the clinical features, radiologic findings, and outcome of these 3 groups. The clinical features of Group I, including age, sex, Glasgow Coma Scale (GCS) score on admission, pupillary status on arrival, and interval from injury to the CT, did not differ significantly from those of Group II (P greater than 0.01). The only difference was the timing of the operation. In Group I, 20 patients (52.6%) received an operation within 4 hours, while in Group IIs, only 7 patients (26.9%) underwent surgery within 4 hours (P less than 0.05). The radiologic findings of Group I, including the thickness and volume of the hematoma, the degree of midline shift, and the frequency of skull fracture, also did not differ from those of Group II (P greater than 0.1). However, the outcome of Group II strikingly differed from that of Group I. The mortality rate was 76.3% in Group I, while it was 44.2% in Group II (P less than 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)
