Neuropsychiatric disorders and GABA]

In the mammalian central nervous system (CNS), the inhibitory GABAergic system is composed of different signaling molecules such as glutamate decaroxylase, vesicular GABA transporters, GABA receptors, GABA transporters and GABA transaminase. A prevailing view is that the balance between excitatory signaling mediated by glutamate and inhibitory signaling mediated by GABA plays a pivotal role in mechanisms underlying the modulation and maintenance of a variety of neural functions. Therefore, abnormalities in a GABAergic signaling molecule would lead to a crisis of severe symptoms relevant to a number of neuropsychiatric disorders. These include epilepsy, depression, schizophrenia, stiff-person syndrome, drug addiction and so on. In this review article, we will summarize recent studies on the relationship between the malfunction of GABAergic signaling molecules and the etiology of these neuropsychiatric disorders. We will also refer to novel strategies on GABAergic signaling molecules other than GABA receptors for therapeutic usefulness in the future.     

Acute Pancreatitis and Cholecystitis Associated with Postpartum HELLP Syndrome: A Case and Review

We report a case of preeclampsia associated with hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome and concomitant nonbiliary acute pancreatitis and cholecystitis in the first postpartum day. A thorough investigation ruled out known etiologies of both pancreatitis and cholecystitis. Following conservative treatment, the patient's HELLP syndrome, pancreatitis, and cholecystitis resolved on the third postpartum day. Preeclampsia is associated with microvascular abnormalities that may involve the splanchnic circulation. These abnormalities may cause not only HELLP syndrome but also pancreatitis and cholecystitis. Recognizing that ischemia can damage not only the liver but also the pancreas and gallbladder, could result in improvements in the diagnosis and management of pancreatitis in patients with preeclampsia.     

Cutaneous lesions of Kikuchi's disease: Evolution of histopathological findings

We report a 38‐year‐old male patient who presented with cutaneous lesions mimicking widespread discoid lupus erythematosus with high‐grade fever, arthralgia and lymphadenopathy. Additional lymph node and skin biopsies, however, revealed karyorrhectic debris without neutrophils and numerous CD68‐positive cells, a characteristic finding of Kikuchi's disease (KD). Comparing skin biopsies on different occasions, we could see different forms of histopathology. The histopathology of skin lesions of KD may vary during the clinical course, which may reflect the stage of the disease.     

Comparative study of functional outcomes of three laparoscopic intestinal surgical procedures

ObjectivesLaparoscopic abdominal surgery (LS) has been prevailing over open surgery (OS). However, its functional outcomes in the aging generation have not been sufficiently examined. We compared changes in physical status and earlier resumption of oral intake between LS and OS.MethodsUsing the Japanese administrative database, we matched variables affecting LS and compared them between LS and OS patients. During the 6-month period from July to December of 2006–2010, we examined the data from data from surviving patients of ≥15 year old who underwent isolated gastrectomy, colectomy, or anterior resection. Functional status was estimated by the Barthel index (BI) at admission and discharge. Outcomes were postoperative complications, BI deterioration, change in BI, and day of recommencing postoperative oral intake.ResultsWe identified 30,763 gastrectomies (laparoscopic: 7297), 31,958 colectomies (laparoscopic: 9364), and 12,545 anterior resections (laparoscopic: 4351). Variation in LS indications was observed in patient and hospital mixes. Among the paired-matched gastrectomy, colectomy, and anterior resection groups, LS was associated with fewer complications and earlier recovery of postoperative oral intake. Laparoscopic anterior resection (LAR) and colectomy were associated with less frequent BI deterioration. Longer operative time was associated with more complications, which then influenced BI deterioration in patients who underwent anterior resection.ConclusionsShorter operative time for LAR was associated with less functional deterioration than for laparoscopic gastrectomy and colectomy. Physicians should consider the appropriate indications for LS by concurrently avoiding unnecessary longer operations and their associated complications. More investment in teaching the skills necessary for LAR is recommended.     

Therapeutic efficacy of intense pulsed light in patients with refractory meibomian gland dysfunction

Purpose

To evaluate the efficacy and safety of intense pulsed light (IPL) combined with meibomian gland expression (MGX) for treatment of refractory meibomian gland dysfunction (MGD).

A Case of In-Stent Neoatherosclerosis 10 Years after Carotid Artery Stent Implantation: Observation with Optical Coherence Tomography and Plaque Histological Findings

We report a patient''s case of slow progressive in-stent restenosis 10 years after bare-metal stent implantation to his carotid artery. We treated the patient with an additional stent placement under a distal filter protection device. Optical coherence tomographic assessment and plaque histology during the carotid artery stenting (CAS) revealed atheromatous change at in-stent neointima, which contained lipid-rich plaque and calcification deposits. These findings suggest that in-stent neoatherosclerosis may play an important role in the pathogenesis of very late stent restenosis after CAS.
