Résumé
BACKGROUND AND PURPOSE: This study aimed to determine the subjective and objective improvements in sleep quality after treatment with gamma-aminobutyric acid (GABA; 300 mg daily) extracted from unpolished rice germ. METHODS: This study was a prospective, randomized, double-blind, and placebo-controlled trial. In total, 40 patients who complained of insomnia symptoms were enrolled and randomly assigned to the GABA treatment group (n=30) or the placebo group (n=10). Polysomnography was performed, and sleep questionnaires were administered before treatment and after 4 weeks of treatment. RESULTS: After 4 weeks of treatment the sleep latency had decreased [13.4±15.7 min at pretreatment vs. 5.7±6.2 min at posttreatment (mean±SD), p=0.001] and the sleep efficacy had increased (79.4±12.9% vs. 86.1±10.5%, p=0.018) only in the GABA treatment group. Adverse events occurred in four subjects (10%). CONCLUSIONS: This study shows that treatment with unpolished-rice-germ-derived GABA improved not only the subjective sleep quality but also the objective sleep efficacy without severe adverse events.

Résumé
A 77-year-old female with a history of osteoarthritis visited our clinic complaining of lower back pain, paresthesia in both legs, and voiding difficulty. Her pain and temperature sensations were diminished below the L1 dermatome, and proprioception was decreased in both feet. The findings of a routine laboratory workup, echocardiogram, and cerebrospinal fluid studies were normal. Spine magnetic resonance imaging revealed high T2-weighted signal intensities and diffusion restriction in the posterior conus medullaris. The patient was diagnosed and treated for posterior spinal artery infarction.

A 45-year-old female visited our clinic due to sudden right leg weakness and sensory loss. Brain and spinal cord magnetic resonance imaging showed widespread cavernous malformations. Cavernous malformation in L1 spine area was accompanied by a subacute stage hematoma with perilesional edema. Sensory loss subsided after corticosteroid therapy. Usually, neurologic deficit by spinal cavernous malformation appears more chronically in the adults compared to children. Treatment options are difficult to establish in a case with multiple cavernous malformations. Identifying hemorrhagic lesions by extensive neuroimaging evaluation could be helpful to select the treatment target for cavernous malformation.

OBJECTIVES: Gamma-aminobutyric acid (GABA) has potential benefits in counteracting the sleep disruption and potential therapeutic effects on blood pressure, stress, cancer, and inflammatory diseases. Recently, High-dose GABA can be extracted from fermented rice germ using lactic acid bacteria. This study aimed to evaluate the effects of GABA natural extracts from fermented rice-germ on sleep latency, subjective sleep quality and insomnia symptoms. METHODS: This was a prospective randomized double-blind placebo-controlled trial performed at Kyung-Hee University hospital at Gangdong from June 2013 to October 2013. Adult (age≥30) patients who was diagnosed of insomnia according to DSM-IV criteria was enrolled. They were randomized into three groups: high dose treatment group 300 mg; low-dose treatment group, 100 mg; and placebo group. Questionnaires including Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), WHO-5 Well-Being Index were performed, and 1-week actigraphy was recorded before and 1 week after the treatment. RESULTS: Total of 114 patients were randomized into 3 groups: high-dose treatment (n=37), low-dose treatment (n=38), and placebo treatment group (n=39). At 1 week after the treatment, PSQI total score and C2 (sleep latency) score significantly decreased in low-dose and high-dose treatment group than the placebo groups [Repeated measures analysis of variance (ANOVA), p=0.017, 0.004 respectively]. ISI score also decreased in the two groups in dose-dependent manner (Repeated measures ANOVA, p=0.037). There were five (4.4%) patients who reported medication adverse events. CONCLUSIONS: This study suggests that treatment of low and high-dose GABA from unpolished rice-germ decreases sleep latency and improve insomnia severity without severe adverse events.

Ventriculoperitoneal shunt (VP shunt) for hydrocephalus is thought to inhibit the closure of processus vaginalis by increasing intraabdominal pressure, thus it promotes the inguinal hernia. We reviewed the incidence and characteristics of the inguinal hernia in VP shunted patients, and tried to estimate the patency rate of processus vaginalis in early childhood. A reprospective review of patients undergone insertion of VP shunt between January 1980 and May 1998 at Seoul National University Children Hospital was done. 262 patients were included in this study. Among them, 28 patients developed inguinal hernia (10.7%). Six patients developed inguinal hernia before the insertion of VP shunt. According to the age of VP shunt, the inguinal hernia developed in 16.2% (12/74) of patients who had undergone VP shunt before 6 months old, 12.4% (11/89) between 6 months and 2 years old and 5.1% (5/99) after 2 years old. Among 22 patients excluding 6 patients who developed hernia before VP shunt, the incidence of inguinal hernia after VP shunt was 8.6% (22/256) with male predominance (M:F=18:4). 8 patients developed inguinal hernia bilaterally (36.4%). It is suggested that at least 14% of processus vaginalis is patent until 2 years old.
