Spontaneous Intracranial Hypotension Treated with Epidural Blood Patch: A Case Report

Spontaneous intracranial hypotension (SIH) is a condition caused by spontaneous cerebrospinal fluid (CSF) leakage, resulting in orthostatic headache as the main symptom, but other symptoms such as memory loss, nausea, and tinnitus may also be present. Various imaging techniques are used to diagnose SIH, with magnetic resonance imaging myelography being an important tool for detecting the leakage site of CSF. Conservative treatments including hydration, bed rest, and intravenous caffeine have been tried with limited success. Epidural blood patch (EBP) is the most commonly performed treatment for SIH after the failure of conservative management. There are different opinions about the EBP procedure (e.g., blind EBP vs. targeted EBP). This report describes the treatment of SIH with targeted EBP according to imaging diagnosis after the failure of initial blind lumbar EBP.

Association between Minimal Change Esophagitis and Gastric Dysmotility: A Single-Center Electrogastrography and Endoscopy Study in Children / 대한소아소화기영양학회지

PURPOSE: Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. METHODS: We retrospectively assessed the records of 157 children without underlying disease who underwent both EGG and upper gastrointestinal endoscopy at Gachon University Gil Medical Center between January 2010 and June 2015. The children were stratified according to the appearance of the esophagus (normal vs. MCE). Between-group differences in EGG parameters and their correlation with each MCE finding were statistically analyzed. RESULTS: Only the power ratio, one of the EGG parameters analyzed, differed significantly between the two groups (MCE, 1.68±3.37 vs. normal, 0.76±1.06; p < 0.05), whereas the other parameters, such as dominant frequency, dominant power, and the ratio of abnormal rhythm, showed no differences. Among children with MCE, significant correlations were noted between erythema and power ratio (p < 0.05), friability and postprandial dominant frequency (p < 0.05), and edema and/or accentuation of mucosal folds and pre-prandial frequency (p < 0.05). Helicobacter pylori infection correlated with postprandial arrhythmia (MCE, 33.59±15.52 vs. normal, 28.10±17.23; p < 0.05). EGG parameters did not differ between children with normal esophagus and those with biopsy-proven chronic esophagitis. CONCLUSION: In children with MCE, gastric dysmotility may affect the development of MCE, manifesting as EGG abnormalities. H. pylori infection may also affect GME. However, larger prospective investigations are needed to confirm these findings.

Effects of Awareness and Knowledge of Energy Drinks on Consumption Patterns among College Students

BACKGROUND: We examined the consumption patterns and the knowledge and awareness of energy drinks to draw up a guideline for energy drink consumption and to give accurate information to college student. METHODS: Data from 324 subjects (186 males and 138 females) were collected using self-administered questionnaires. The study participants were recruited from the Gyeonggi-do, Seongnam area between March and June 2013. RESULTS: The results showed that there was a significant gender-based difference in awareness of energy drinks- 56.5% (78/139) of the males and 78.9% (71/90) of the females had negative awareness (P<.001). As for recognizability of taurine by awareness of energy drinks, there were intergroup differences: the mean was 3.89 for the group with positive awareness and 3.31 for the negative awareness group (P=.001). The odds ratio for awareness of energy drinks was 2.75 (95% CI:1.05-7.18) and those with positive awareness consumed more than those with negative awareness (P=.039). CONCLUSIONS: This investigation on the factors that affect energy drinks consumption behaviors is of significance in that it helps make known the high caffeine content of energy drinks, and accurate knowledge of the side effects and appropriate consumption.

The Measurement of Opening Angle and Orifice Area of a Bileaflet Mechanical Valve Using Multidetector Computed Tomography

BACKGROUND AND OBJECTIVES: The aim of this study was to assess mechanical valve function using 64-slice multidetector computed tomography (MDCT). SUBJECTS AND METHODS: In 20 patients (mean age, 50+/-12 years; male-to-female ratio, 10:10), 30 St. Jude bileaflet mechanical valves (15 aortic and 15 mitral valves) were evaluated using MDCT. We selected images vertical and parallel to the mechanical valve. The valve orifice area (OA) and valve length were determined by manual tracing and the opening and closing angles were measured using a protractor. The OA and length of the mechanical valves were compared with the manufacturer's values. RESULTS: The geometric orifice areas (GOAs) based on the manufacturer's values and the OAs determined by MDCT were 3.4+/-0.2 cm2 and 3.4+/-0.3 cm2 for the mitral valves and 2.1+/-0.3 cm2 and 2.1+/-0.4 cm2 for the aortic valves, respectively. The correlation coefficients between the OA measures were 0.433 for the mitral valves and 0.874 for the aortic valves (both p<0.001). The lengths based on the manufacturer's values and determined by MDCT were 29.3+/-1.99 mm and 29.6+/-1.65 mm for the mitral valves and 21.5+/-2.1 mm and 20.7+/-2.3 mm for the aortic valves, respectively. The correlation coefficients between the measures were 0.651 for the mitral valve and 0.846 for the aortic valve (both p<0.001). The opening and closing angles determined by MDCT were 10.9+/-0.6degrees and 131.1+/-3.2degrees for the mitral valves and 11.1+/-0.9degrees and 120.6+/-1.7degrees for the aortic valves, respectively. CONCLUSION: MDCT is an accurate modality with which to assess the function and morphology of bileaflet mechanical valves.

Isolated Left Ventricular Noncompaction Cardiomyopathy Accompanied by Severe Mitral Regurgitation

Isolated left ventricular noncompaction cardiomyopathy (IVNC) is a cardiomyopathy thought to be caused by arrest of normal embryogenesis of the endocardium and myocardium. This abnormality is often associated with other congenital cardiac defects. A 21-year-old man presented to the emergency department with worsening exertional dyspnea during the previous 2 months. Two-dimensional and Doppler echocardiography revealed an enlarged left atrium (LA) and a markedly dilated left ventricle (LV) with preserved LV systolic function, severe mitral valve regurgitation, and prolapse due to chordae rupture. The myocardium of the LV and right ventricle (RV) had excessively prominent trabeculations and deep intertrabecular recesses. He is the first patient in Korea who has undergone mitral valve replacement surgery because of severe mitral valve regurgitation and prolapse due to chordae rupture accompanied by IVNC.

A Case of Extensive Pulmonary Laceration Caused by Nonpenetrating Trauma

Extensive laceration of the lung itself has relatively little attention as a threat to life compared with other intrathoracic organ injuries. The incidence of pulmonary laceration extensive enough to require thoracotomy is rare, but is higher than expected. The diagnosis of extensive pulmonary laceration may be difficult, but this injury should be suspected with attention and early thoracotomy can be carried out in indicated cases. Recently, thoracoscopy has assumed a major role in the management of a variety of surgical diseases of the chest. We experienced a case of extensive pulmonary laceration caused by nonpenetrating trauma, which underwent lobectomy by thoracoscopic surgery. A 21-year-old man who was injured in a motocycle accident was brought to Emergency Room from the scene by an ambulance, and complained of chest pain and dyspnea. A chest roentgenogram showed a hemothorax and fractures of the posterior ends of the right seventh, eighth, and ninth ribs. A chest tube was inserted. Thirteen hundred ml of blood was drained through the chest tube during the next one hour. Emergency right mini-thoracotomy revealed extensive laceration of the lower lobe extending to the pulmonary hilum. The lower lobe was the most badly torn. A lower lobectomy was done by video-assisted thoracic surgery (VATS). He complained less postoperative pain and the postoperative course was uneventful.

A Case of Primary Rhabdomyosarcoma in the Left Cerebello-Pontine Angle

The primary rhabdomyosarcoma of the brain is very rare. There are only 14 cases reported in the literatures till 1975, and the majority of them were arised in the cerebellum. The intracranial rhabdomyosarcomas may be originated from the multipotent mesenchymal cells of aberrent muscle tissue in the leptomeninges. The histological 3 types are adult pleomorphic, alveolar and embryonal type. The demonstration of cross-striation is confirmed for diagnosis of this tumor. All of these tumors tend to have a short clinical course, but the survival time seems to be slightly improved by surgical excision followed by radiotherapy. We have recently experienced one case of primary rhabdomyosarcoma in the left cerebellopontine angle of 9 year-old girl, which was confirmed by operation and complete autopsy.

Cerebral Paragonimiasis: An Analysis of 7 Cases

Pagonimus Westmani, occuring as an important human infestation of the lung, is widely distributed in the Far East ; Korea, Japan, China and the Philippines. Since Otani found the parasites for the first time in the human brain in 1887, it has been established that cerebral infestation occurs with the highest frequency among extrapulmonary involvement. In 0.8 to 25 percent of patients infested with the lung flukes cerebral paragonimiasis may be developed. The larvae may procedure arachnoiditis, abscess, fibrous cystic lesions and granulomas in the brain. Based on a review of the literatures and upon the 7 cases of cerebral paragonimiasis which have been observed by the authors at the National Medical Center, Seoul, Korea, the following points are stressed. 1) Males had a significantly higher prevalence than females. Cerebral paragonimiasis was most commonly found in young adults(16 to 25yrs). 2) Clinically the patients with cerebral involvement were characterized by Jacksonian type of epilepsy, headache and visual disturbance. Mental deterioration, hemiplegia, hemihypesthesia, homonymous hemianopsia and optic atrophy were the five major signs. 3) The patients having symptoms for less than 6 months developed mild leukocytosis in many cases. All the cases of cerebral paragonimiasis revealed positive reaction in the intradermal tests with purified antigens of P. Westermani. 4) On skull films multiple round or oval cystic calcification was diagnostic value for cerebral paragonimiasis. On angiogram vascular staining and abnormal vessels were not disclosed. On pneumoencephalogram subcortical atrophy or filling defect of the ventricle may be showed. 5) The predilection area of the granuloma and fibrous cystic mass were the occipital, posterior parietal and posterior temporal lobes. 6) The patients with chronic stabilized cerebral paragonimiasis. having intractable symptoms and signs, could not be improved with Bithionol treatment. But headache, vomiting, visual disturbance, facial weakness and especially intractable seizure were improved in our cases treated with surgical operation.

A Case of Intraventricular Oligodendroglioma Associated with Arterio-Venous Malformation

Bailey and Cushing described the oligodendroglioma firstly in 1926. The oligodendroglioma is rare tumor and involves the ventricular system in 7% to 10% of all cases. The authors present a case of intraventricular oligodendroglioma associated with arterio venous malformations in a 34 year old male who had the history of visual disturbance and mental deterioration, for one month. The diagnosis was confirmed by operation and autopsy.

Analysis of 6 Cases of Brain Stem Glioma

An analysis of recent experiences for the brain stem glioma with surgery and autopsy established confirmation of the characteristic symptoms and signs, and of diagnostic criterias of Conray-ventriculogram and vertebral-angiogram. The cases consisted of 2 cases of exophytic brain stem glioma and 4 cases of pontomedullary glioma, and 5 of 6 patients had the signs of the increased intracranial pressure in this cases. A resurgence of interest in the Conray ventriculogram has been produced by cut-off sign of aqueduct of Sylvius in 2 cases of the exophytic brain stem glioma. The survival period in adults (1-3 years) were longer than that in children (less than 3 months) in this series.

Clinical Analysis of Brain Scans Using Technetium-99M

Technetium 99 M pertechnetate has become a valuable for the radioisotopic brain scan. This was introduced by Haper in 1963 and is now widely used in the medical field. The advantages are easy administration, high count rate with potential for high speed scanning, absence of beta radiation and decreasing time for test. We used Siemens Scintimat 2 Scanner with a 3x2 inch Na(T1) crystal and 151-hole collimator in our study. 10 mci Technetium 99 M was injected intravenously and obtained both lateral, anterior and posterior view in 80 cases of brain lesion from Mar. 75 to Sep. 76. The scans were classified as positive, negative and suspicious. The overall detection rate in 40 cases of brain tumors was 60%, especially high uptake in mengioma, malignant pituitary tumor, astrocytoma, metastatic brain tumor and acoustic neuroma. But in nontumors diseases of the brain including CVA, head injury and hydrocephalus the uptake rate was a little value.

Malignant Schwannoma Associated with Von Recklinghausen' Disease

Malignant peripheral nerve tumors are very rare and derived from the neurofibromatosis in about 13%. There are two classes of malignant tumors in the peripheral nerve, one those of mesoblastic origin, is far most common and made up of malignant neurofibroma and much common fibrosarcoma, and metastasis in 20% of fibrosarcoma, and the other is neuroepithelial origin. These are characterized by increased cellularity, atypical form of cells, mitoses and invasiveness. The choice treatment is radical removal of the tumor, and not affected the prognosis by radiation or chemotherapy. We have been recently experienced of one case of malignant schwannoma on the cervical roots in a case of von Recklinhausen's disease.

Malignant Pituitary Adenoma

The authors present 2 cases of malignant pituitary adenoma. One case has remote metastases to the right frontal lobe, and the other case has invasion into the adjacent temporal lobe and malignant features histologically. Malignant pituitary adenoma constitute less than 1% of the large reported series of pituitary adenoma, which defined as (1) it burst its capsule to invade the adjacent nervous structures or bone, (2) it shows malignant features histologically, such as frequent mitoses, anaplasia with hyperchromatic pleomorphic cells, loss of alveolar arrangement, and (3) presence of distant metastases.

A Case of Bilateral Cerebellar Tuberculomas

Hematogenous spread from tuberculous lesions of other parts of the body represent the origin of intracranial tuberculomas. In most series of the literature, the cerebellum has about two thirds and the cerebral hemispheres about one third of the intracranial tuberculomas. It may occurs as a single lesion, but multiple intracranial tuberculomas varies from 10% to 33% of the cases due to the hematogenous spread. Calcium deposits are rare, occurring in about 6% of cases. Ramamurthi and Varadarajan described the two types of the intracranial tuberculoma; 1. Superficial and vascular type, produces early focal signs of increased intracranial pressure. 2. deep and avascular type, accompanied by signs of increased intracranial pressure. We have been experienced in one case of symmetrical and bilateral cerebellar tuberculomas probably originated from the pulmonary lesion.
