RESUMEN

Vasohibin-1 (VASH1) is an angiogenesis inhibitor, while vasohibin-2 (VASH2) is a proangiogenic factor. The roles of VASH1 and VASH2 expression in gastroenterological cancers remain unclear. We searched for relevant literature, specifically studies on gastroenterological cancer, and evaluated the relationship between VASH expression and clinical outcomes. Nine studies on VASH1 involving 1,574 patients were included. VASH1 expression was associated with the TNM stage [OR (odds ratio) 2.05, 95% CI (confidence interval) 1.24-3.40], lymph node metastasis (OR 1.79, 95% CI 1.24-2.58), lymphatic invasion (OR 1.95, 95% CI 1.41-2.68), and venous invasion (OR 2.49, 95% CI 1.60-3.88); poor clinical outcomes were associated with high VASH1 expression. High VASH1 expression was associated with a significantly shorter overall survival (OS) [HR (hazard ratio) 1.69, 95% CI 1.25-2.29] and disease-free survival (DFS) (HR 2.01, 95% CI 1.28-3.15). Three studies on VASH2 involving 469 patients were analyzed. VASH2 expression was associated with the TNM stage (OR 4.21, 95% CI 1.89-9.51) and venous invasion (OR 2.10, 95% CI 1.15-3.84); poor clinical outcomes were associated with high VASH2 expression. High VASH2 expression was associated with a significantly lower OS (HR 1.61, 95% CI 1.09-2.37). In conclusion, high VASH1 and VASH2 expression levels were associated with poor clinical outcomes and prognosis in patients with gastroenterological cancers.

RESUMEN

PURPOSE: It was recently identified that the vasohibin family may regulate angiogenesis through suppression by the vasohibin-1 gene and promotion by the vasohibin-2 gene. We assessed vasohibin expression in gastric cancer patients and its effect on their prognosis. METHODS: We evaluated vasohibin immunohistochemical expression in 210 patients with gastric cancer, who underwent radical surgery. The patients were divided first into a vasohibin-1-positive group and a vasohibin-1-negative group, and then into groups with high or low vasohibin-2 expression, to allow us to investigate the clinicopathological factors of prognosis retrospectively. RESULTS: There were 139 patients in the vasohibin-1-positive group and 71 patients in the vasohibin-1-negative group, among which there were and 108 with high vasohibin-2 expression and 102 with low vasohibin-2 expression. Vasohibin-1 was associated with Ly (P = 0.003) and pT (P = 0.037), whereas vasohibin-2 was associated with Ly (P < 0.001), V (P < 0.001) and pStage (P < 0.001). Overall, cancer-specific and relapse-free survival rates were lower in the vasohibin-1-positive (P = 0.034, P < 0.001, P = 0.002, respectively) and high vasohibin-2 expression (P = 0.004, P = 0.003, P < 0.001, respectively) groups. Multivariate analysis revealed that vasohibin-1 expression was associated with cancer-specific (P = 0.014, hazard ratio [HR] 4.454) and relapse-free (P = 0.035, HR 2.557) survival and vasohibin-2 expression tended to influence relapse-free survival (P = 0.051, HR 2.061). Grouping patients by vasohibin expression status combinations showed correlation among their expressions (P = 0.005). Overall, cancer-specific and relapse-free survival rates were lowest in the vasohibin-1-positive and high vasohibin-2 expression group. CONCLUSION: Our findings demonstrate that vasohibin-1 and vasohibin-2 could be novel biomarkers for predicting gastric cancer prognosis.

RESUMEN

BACKGROUND: Angiodysplasia of the gastrointestinal tract is a rare vascular pathology that sometimes causes massive hemorrhage. Angiodysplasias are particularly difficult to find in the small intestine for anatomical reasons, often impeding their diagnosis and treatment. Lesion localization is a major challenge in cases of small bowel bleeding requiring surgical intervention. CASE PRESENTATION: The present case was a 52-year-old woman who was urgently hospitalized with repeated tarry stools. Surgical intervention was chosen after conservative treatment failed to improve her condition. The source of bleeding was suspected to be a vascular lesion discovered in the small intestine during a past double-balloon endoscopy. Abdominal contrast computed tomography revealed a jejunal hemorrhage. We chose selective arterial embolization to stabilize her hemodynamics followed by surgical intervention as her treatment plan. Several embolic and contrast agents (cyanoacrylate, indigo carmine, and Lipiodol) were combined to help identify the location of the lesion during surgery. This multi-pronged approach allowed us to localize the lesion under laparoscopic guidance with high confidence and accuracy, and to excise a 6-cm segment of the small intestine. The lesion was histologically diagnosed as angiodysplasia. No re-bleeding has been observed since the operation. CONCLUSION: We report our experience with a case of jejunal angiodysplasia, which was localized with selective arterial embolization using an array of embolic and contrast agents, and then excised laparoscopically. Selective arterial embolization with indigo carmine dye to treat small bowel bleeding preoperatively not only makes the surgery safer by stabilizing the patient's hemodynamics, but is also very useful for localizing the lesion intraoperatively.

RESUMEN

BACKGROUND: Vasohibins (VASH), which are angiogenesis regulators, consist of Vasohibin-1 (VASH1) and Vasohibin-2 (VASH2). VASH1 is an angiogenesis inhibitor, while VASH2 is a proangiogenic factor. Patients with esophageal squamous cell carcinoma (ESCC) with high tumor expression levels of VASH1 and VASH2 have been reported to show a poor prognosis. The clinical significance of VASH concentrations in the blood of patients with ESCC has not yet been investigated. METHODS: Plasma samples from 89 patients with ESCC were analyzed, and the relationships between the plasma VASH concentrations and the clinicopathological factors of the patients were evaluated. Immunohistochemical examination (IHC) of the resected tumor specimens for VASH was performed in 56 patients, and the correlation between the plasma VASH concentrations and tumor expression levels of VASH was analyzed. RESULTS: The patient group with high plasma concentrations of VASH1 showed a higher frequency of lymph node metastasis (P = 0.01) and an invasive growth pattern (P = 0.05). Furthermore, poorly differentiated cancer occurred at a higher frequency in the patient group with high plasma concentrations of VASH2 (P < 0.01). High tumor expression levels of VASH1 were encountered more frequently in the patient group with high plasma concentrations of VASH1 (P = 0.03), and high tumor expression levels of VASH2 were encountered more frequently in the patient group with high plasma concentrations of VASH2 (P = 0.04). CONCLUSIONS: In patients with ESCC, high plasma concentrations were associated with poor clinical outcomes for both VASH1 and VASH2. We propose that results indicate that plasma VASH1 and VASH2 are useful biomarkers in patients with ESCC.

RESUMEN

A 69-year-old man presented to our hospital because of epigastric pain. A type 2 lesion was seen in the lesser curvature of the antrum of the stomach. A moderately differentiated adenocarcinoma(human epidermal growth factor receptor 2-negative) was diagnosed by biopsy. Abdominal computed tomography showed a mass shadow 52mm in diameter in the pyloric region invading the surrounding organs, but no evidence of distant metastasis. Chemotherapy with S-1 and cisplatin(SP therapy)was initiated because of a diagnosis of locally advanced gastric cancer. After 2 courses of chemotherapy, the tumor shrinkage rate was 70%, confirming that treatment was effective. However, severe skin disorders developed, precluding the continuation of chemotherapy. Staging laparoscopy showed no evidence of peritoneal dissemination, but invasion into the superior mesenteric vein was noted. The tumor was resected by pancreaticoduodenectomy with partial resection of the venous wall. Pathological examination of the resected specimens provided a definite diagnosis of neuroendocrine cell carcinoma. As of 1 year and 7 months after surgery, there has been no observation of metastasis or recurrence. SP therapy was suggested to be a useful regimen for preoperative chemotherapy in patients with locally advanced neuroendocrine cell carcinoma.

RESUMEN

BACKGROUND/AIMS: This retrospective study evaluated 21 patients with early enteral feeding (EEF group) and 22 patients without early enteral feeding (non-EEF group) who underwent open total gastrectomy followed by Roux en Y reconstruction and were RO resectable cases. METHDOLOGY: Postoperative complications and course, postoperative/preoperative body weight, whole meal intake, and nutritional, inflammatory, and immunological parameters were recorded and evaluated in both groups. RESULTS: Postoperative meal intake was significantly higher and the first day of defecation was significantly earlier in the EEF group than in the non-EEF group. There were no significant differences between the 2 groups in the blood laboratory data and the rate of complications. In patients with complications, lymphocyte counts and postoperative body weights were compared as indicators of immunostimulation. The lymphocyte counts 7 days after operation and postoperative/preoperative body weight were significantly higher in the EEF group than in the non-EEF group. CONCLUSIONS: Although immunostimulation-like findings were observed in the patients with complications after surgery in the present study, the significance of EEF was not clarified because of the lack of cases whose conditions were severe. EEF should be used especially for patients in whom severe disease is possible and avoidance of TPN is desirable.

RESUMEN

A 36-year-old man presented with acute cerebral infarction in the right frontal lobe associated with right internal carotid artery dissection (CAD). Enhanced computed tomography revealed right greater horn of the hyoid bone in close proximity to the right internal carotid artery (ICA). It was speculated that mechanical compression of the internal carotid artery by the hyoid bone induced by neck rotation was related to ICA dissection. Greater knowledge of the association between the hyoid bone and the CAD will lead to increased awareness and appropriate diagnosis.

RESUMEN

RATIONALE: The mesodiverticular band (MDB) of a Meckel's diverticulum (MD) is a rare, yet notable etiology of small bowel obstruction (SBO) in adults. Due to the nonspecific symptoms and challenging diagnosis thereof, preoperative clinical suspicion and strategic management are crucial for achieving optimal outcomes. Therefore, we presented a case in which laparoscopic surgery was strategically performed to alleviate ileus, due to a preoperative diagnosis of SBO, suspected to be secondary to an MD with a concomitant MDB. PATIENT CONCERNS: A 32-year-old male patient presented with a half-day's duration of epigastric pain, abdominal distension, and tenderness, resulting in the working diagnosis of SBO. DIAGNOSES: Initial non-contrast computed tomography (CT) revealed SBO without signs of strangulation, postulated to be caused by an MD and concomitant MDB, resulting in conservative management. The symptoms persisted, necessitating contrast-enhanced CT. However, the dilated bowel loop suggestive of an MD that had been observed on non-contrast CT could not be confirmed on contrast-enhanced CT. INTERVENTIONS: Decompression therapy using a long tube provided minimal relief, prompting laparoscopic surgery on the 5th day post-admission for diagnostic and therapeutic purposes. OUTCOMES: An MD resection effectively relieved the SBO. The histopathological analysis revealed a true diverticulum with ectopic pancreatic tissue, confirming the diagnosis of an MD. At the band site, vascular and neural structures were encased in a sheath, consistent with the remnants of the vitelline duct mesentery; and histopathologically diagnosed as an MDB. The postoperative course was uneventful, and the patient was discharged on the 9th day, postoperatively. LESSONS: Decompression therapy and strategic laparoscopic surgery based on the preoperative working diagnosis of SBO yielded favorable outcomes, highlighting the importance of the early clinical suspicion of an MD and a concomitant MDB, as the etiology of SBO. The imaging variability and rarity of an MD in adults emphasizes the need for a heightened awareness and an accurate diagnosis for optimal management. Early intervention should be deliberated for patients with suspected intestinal ischemia. However, this case accentuates the clinical implications of strategic planning and employing minimally invasive techniques in the management of an MD-related SBO in adults.

RESUMEN

BACKGROUND: Gastritis cystica profunda (GCP), commonly observed in remnant gastric anastomosis, is associated with developing gastric cancer. CASE: This case report describes a patient with GCP in a previously unoperated stomach that mimicked a pyloric submucosal tumor and caused anorexia, which is rare in clinical practice. PATIENT CONCERNS: A 72-year-old woman presented with loss of appetite and weight. DIAGNOSES: Gastroscopy detected a 20 mm diameter submucosal tumor near the pylorus. Computed tomography and magnetic resonance imaging identified a cystic lesion, unlike a usual submucosal tumor in the stomach. The diagnosis was difficult, even with endoscopic ultrasound-guided fine-needle aspiration. INTERVENTIONS: Surgery was performed for diagnosis and treatment. The lesion was resected using a submucosal dissection technique after an incision of the gastric wall during open laparotomy. Histopathological examination confirmed the diagnosis of GCP and revealed no dysplasia or cancer. OUTCOMES: Anorexia resolved after the surgery. Residual or recurrent lesions were not detected during follow-up examinations performed 1 year after surgery. LESSONS: GCP occurring in a previously unoperated stomach as a macroscopic lesion like a submucosal tumor causing some symptoms is rare. GCP is associated with a risk of developing cancer. Therefore, careful evaluation and management during treatment are required.

RESUMEN

INTRODUCTION: This case report describes a patient who underwent laparoscopic resection of the mucocele of the appendix secondary to endometriosis, a rarity in clinical practice. PATIENT CONCERNS: The patient was a 38-year-old woman with a history of endometriosis and an ovarian cyst who sought medical advice with a chief complaint of mild right lower abdominal pain. DIAGNOSES: Computed tomography and ultrasonography of the abdomen revealed a cystic lesion at the distal end of the appendix without definitive findings of malignancy. Colonoscopy revealed a submucosal tumor-like elevation at the appendiceal orifice. Appendiceal mucocele was suspected preoperatively. INTERVENTIONS: The lesion was resected laparoscopically. Secondary ileocecal resection with lymphadenectomy was possible if the resected specimen was pathologically diagnosed as a malignant tumor with the risk of lymph node metastasis. OUTCOMES: The resected specimen was pathologically diagnosed as an appendiceal mucocele secondary to endometriosis; therefore, additional surgery was avoided. CONCLUSION: Although appendiceal mucoceles secondary to endometriosis are rare, laparoscopic surgery in which only the lesion was resected is a useful strategy for the treatment and pathological diagnosis of appendiceal mucoceles without findings of malignancy.

RESUMEN

BACKGROUND: We previously introduced the Five-Parameter System (FPS), which exclusively evaluates keratinized cellular findings, for use in cytology examinations of oral well-differentiated squamous cell carcinoma (SCC) and carcinoma in situ (CIS) specimens, as they occasionally lack nuclear atypia and can be challenging for categorization by The Bethesda System (TBS). This study was conducted to determine whether FPS parameters are detectable even in oral SCC/CIS specimens with apparent nuclear atypia. SUMMARY: Oral cytology specimens were obtained together with biopsy tissue samples. They were obtained from 59 malignant (HSIL and SCC) and 29 not-definitely malignant (NILM to ASC-H) specimens diagnosed using TBS. Following re-confirmation of the original TBS categorization, the specimens were re-evaluated using FPS. One or more of the FPS parameters were noted in 69 of 70 malignant specimens examined, of which 11 had been diagnosed by TBS as not-definitely malignant. The remaining one malignant specimen was diagnosed as SCC with only TBS. FPS parameters #1 (concentric arrangement), #2 (large cell number), #3 (bizarre-shaped cells), #4 (keratoglobules), and #5 (uneven filamentous cytoplasm) were observed only in malignant cases, while none were revealed in not-definitely malignant specimens. Finally, TBS supplemented with FPS achieved sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of 100%. KEY MESSAGES: FPS parameters are included in most examinations of oral cytology specimens. Thus, FPS is highly recommended for use in cytology examinations of oral SCC regardless of differentiation degree to confirm judgment based on TBS, a mandatory standard, as well as to cover its limitation of mainly evaluating nuclear atypia. FPS is considered to be an important diagnostic tool for oral cytology, especially in triage cases, which are challenging for TBS. Cytopathology should not be limited to only nuclear findings but be based on whole-cell morphology.

RESUMEN

BACKGROUND/AIM: In the Japanese Classification of Gastric Carcinoma, T4a gastric cancer is defined as tumor invasion contiguous to the serosa or penetrating the serosa with exposure to the peritoneal cavity. The aim of this study was to assess the impact of T4a subclassification of gastric cancer on survival. PATIENTS AND METHODS: A total of 326 patients with T4a cancer who had undergone gastrectomy were enrolled. The T4a tumors were classified into two groups: serosa-contiguous or serosa-exposed. RESULTS: The serosa-exposed group had a significantly worse prognosis, and multivariate analysis identified the T4a subclass as an independent prognostic factor. Analysis of the risk factors for recurrence identified the T4a subclass as a significant risk factor for peritoneal recurrence in patients undergoing curative gastrectomy. CONCLUSION: The serosa-contiguous and serosa-exposed subgroups of T4a gastric cancer showed different biological behaviors. These groups may need to be treated as separate.

RESUMEN

BACKGROUND: Intestinal knot formation, in which two segments of the intestine become knotted together, can result in intestinal obstruction. An ileo-ileal knot refers to knot formation between two ileal segments and is a very rare benign disease. We report a case of strangulated bowel obstruction caused by true ileo-ileal knot formation. CASE PRESENTATION: An 89-year-old woman was referred to our hospital with the diagnosis of intestinal obstruction. Contrast-enhanced computed tomography revealed the small bowel forming a closed loop, with poor contrast effect. Based on the findings, the patient was diagnosed as having strangulated bowel obstruction, and emergency surgery was performed. At laparotomy, two segments of the ileum were found to be tied together forming a knot, and both segments were necrotic. Although it was necessary to release the strangulated small bowel, we did not immediately release the knot, but first proceeded with ligation of the mesenteric vessels to the strangulated small bowel to prevent dissemination of toxic substances from the necrotic bowel into the systemic circulation. The surgery was completed with resection of the necrotic ileum and anastomosis of the small intestine. The postoperative course was uneventful, and the patient was discharged home. CONCLUSION: We encountered a case of strangulated bowel obstruction caused by true ileo-ileal knot formation. Resection of the necrotic small intestine without releasing the knot could be performed safely, and might be considered as an option of surgical procedure.

RESUMEN

RATIONALE: Chronic obstructive pulmonary disease (COPD) is associated with increased morbidity and mortality from cardiovascular disease. Although a close association between COPD and atherosclerosis has been speculated, such scientific information is limited. OBJECTIVES: To evaluate subclinical atherosclerosis in smokers with airflow limitation. METHODS: The subjects of this study were healthy middle-aged men. Smokers with airflow limitation (n = 61) and age-matched control smokers (n = 122) and control never-smokers (n = 122) without airflow limitation were included in the present study. Subjects with diabetes, acute infection, and respiratory disease other than COPD were excluded beforehand. All subjects underwent chest radiogram, spirometry, blood sampling, and carotid ultrasonography. We determined carotid intima-media thickness and focal atheromatous plaque as indicators of subclinical atherosclerosis. MEASUREMENTS AND MAIN RESULTS: Mean carotid intima-media thickness was greater in smokers with airflow limitation than in control smokers (P < 0.01) and control never-smokers (P < 0.005). Focal carotid plaque was significantly more prevalent in smokers with airflow limitation than in control never-smokers (P < 0.005). Multivariate analyses showed significant associations between thickened intima-media thickness and decreased percent predicted FEV(1) (P = 0.001) and between plaque and log(10) C-reactive protein (P = 0.013) independent of age, pack-years of smoking, body mass index, peripheral mean arterial pressure, heart rate, glucose, and low-density lipoprotein cholesterol. CONCLUSIONS: Smokers with airflow limitation had exaggerated subclinical atherosclerosis. This study suggests that middle-aged men who are susceptible to COPD may also be susceptible to vascular atherosclerosis by smoking, and atherosclerotic change starts early in the disease process of COPD.

RESUMEN

BACKGROUND/AIM: Several studies have investigated prognostic factors in patients with T2 gastric cancer, but no consensus has been reached to date. The aim was to investigate the clinicopathological significance of the status of tumor invasion into the muscularis propria (MP) in T2 gastric cancer patients. PATIENTS AND METHODS: A total of 113 patients with T2 cancer were enrolled. The status of caner invasion was analyzed according to width (extent of horizontal invasion) and depth (extent of vertical invasion). RESULTS: The prognosis of the group with wide width of invasion (≥1.5 cm) was significantly poorer than that of the group with narrow width of invasion (<1.5 cm) (p=0.001). Multivariate analysis identified the width, and not the depth, as an independent prognostic factor. The analysis according to AJCC N stage showed that the width, and not the nodal status, was an independent prognostic factor in the N2-N3 patients (p=0.005). CONCLUSION: Measurement of the width of tumor invasion into the MP was useful to understand the malignant potential of T2 gastric cancer.

RESUMEN

Invasive ductal adenocarcinoma (IDA) of the pancreas (IDAP) originating from the ductal gland has a poor prognosis. Noninvasive carcinomas are principally intraductal papillary mucinous carcinomas (IPMCs) and pancreatic intraepithelial neoplasms 3 (PanIN-3). Small papillary-cohesive clusters, individually well-enveloped nuclei in well-preserved cytoplasm, centrally located nuclei, small nuclei (about 10 mum), euchromatin, clearly defined cell borders, small cytoplasm without prominent anisocytosis and no cytoplasm more than 21 mum in shortest diameter, a mixture of goblet cells, and a pleomorphic aspect are common in IPMC and intraductal papillary mucinous neoplasm (IPMN), whereas malignancy in nuclei are observed only in IPMC. PanIN-3 cells have small papillary-cohesive and compact clusters, a monomorphic aspect, and small dense cytoplasm and are highly suggestive of malignancy. IDA cells have loose sheet and solid clusters, poorly preserved cytoplasm, nuclei that tend to adhere to each other, large nuclei, a combination of large nuclei (short diameter <15 mum) with hyperchromatin, a monomorphic aspect, and abundant cytoplasm more than 21 mum in the shortest diameter. To preoperatively differentiate noninvasive IPMC and PanIN-3 from IDAP, these features would be clinically very useful.

RESUMEN

A 32-year-old man who had experienced fever and a pulsating headache of the right occipital region for a month and a transient left hemianopia and numbness in the left arm two weeks prior to presentation was admitted to our hospital because of a seizure. Fluid-attenuated inversion recovery and diffusion-weighted magnetic resonance imaging (MRI) showed high-intensity signals, without reduction of apparent diffusion coefficient value, in the right temporo-occipital cortices. Proton MR spectroscopy (1H-MRS) indicated a decrease in N-acetylaspartate, and single-photon emission CT (SPECT) showed hyperperfusion in the right temporo-occipital territory. An examination of the cerebrospinal fluid showed an elevation of mononuclear cells and the presence of anti-glutamate epsilon2 receptor antibodies. All abnormalities shown by these imaging techniques were normalized in the clinical course. This report suggests that MRI, 1H-MRS and SPECT studies were useful in understanding the pathogenesis of encephalitis associated with glutamate receptor antibodies.

RESUMEN

We report a forty-six-year-old man with a past history of brain abscess managed by surgical drainage and recurrent ischemic strokes. After treatment of brain abscess, he had been on medication for symptomatic epilepsy, but had ceased medication by his judgment. He was taken to a hospital in an ambulance for an epileptic seizure. In the hospital he suffered from drug-induced renal dysfunction caused by the intravenous anti-epileptic drug, and right hemiparesis due to ischemic stroke occurred on the third hospitalization day. He was transferred to our hospital to get a treatment for renal failure. His renal function improved gradually by hemodialysis, but an ischemic stroke recurred in the right cerebellar hemisphere. Closer examinations on the mechanisms of his strokes revealed the draining of right superior vena cava (RSVC) directly into the left atrium (LA), persistent left superior vena cava (PLSVC) and atrial septal defect (ASD). He had a rare anomaly of the systemic venous return. It seemed that his repeated strokes were caused by paradoxical embolism through the draining of RSVC to LA, and air or thrombi in the infusion lines other than intravenous thrombi was thought to be an embolic cause in this case.

RESUMEN

So-called "idiopathic" autism, which exhibited no major complications before diagnosis is well-known as one of the risk factors for epilepsy. This retrospective follow-up study aimed to clarify the characteristics of epilepsy in the autism; onset of seizure, seizure types, EEG findings and epilepsy outcome and the differences as a group between the autism with epilepsy and those without epilepsy. One hundred thirty individuals with autistic disorder or atypical autism diagnosed in childhood were followed up over 10 years and were evaluated almost every year up to 18-35 years of age. Their medical records related to perinatal conditions, IQ, social maturity scores and several factors of epilepsy were reviewed in October 2005. Thirty-three of the follow-up group (25%) exhibited epileptic seizures. The onset of epilepsy was distributed from 8 to 26 years of age. Two types of seizure were observed; partial seizure with secondarily generalized seizure and generalized seizure. Twenty of the epileptics (61%) showed the partial seizure. Although 18% of the non-epileptic group exhibited epileptic discharges on EEG, 68% of the epileptic group revealed epileptiform EEG findings before the onset of epilepsy. No differences were observed concerning the sex ratio, autistic disorder/atypical autism and past history of febrile seizures between the epileptic and non-epileptic groups. Lower IQ, lower social maturity score and higher frequency of prescribed psychotropics were observed in the epileptic group compared to the non-epileptics. Idiopathic autism was confirmed as the high risk factor for epilepsy. Epileptiform EEG findings predict subsequent onset of epileptic seizures in adolescence. Epilepsy is one of negative factors on cognitive, adaptive and behavioral/emotional outcomes for individuals with autism.

RESUMEN

OBJECTIVE: To formulate cytologic features for differential diagnosis of basal cell adenoma (BCA). STUDY DESIGN: The usefulness of 5 items for a cytologically definitive diagnosis of BCA was examined. The 5 items in 8 BCA and 22 non-BCA cases (adenoid cystic carcinoma [ADCC], basal cell adenocarcinoma, myoepithelioma, pleomorphic adenoma and polymorphous low-grade adenocarcinoma) that displayed mimicking cytology were examined cytologically. RESULTS: The useful items were < 5.1 microm in mean of epithelial nuclear short diameter; mild atypia on definitive diagnosis; stromal cell cluster combining smooth margin surrounding the epithelial cell cluster or containing the epithelial cell cluster; epithelial clusters surrounded by or adhered to a thick, hyalinized smooth margin without stromal cluster; and closely fastened, tight clusters with denser cytoplasm than ADCC, but an indistinct border, with oval nuclei and no hyaline cells. CONCLUSION: Five items are useful criteria for BCA.
