Gliomatosis peritonei (GP) indicates the peritoneal implantation of mature neuroglial tissue and is usually accompanied by ovarian mature or immature teratoma. Here, we report a case of ovarian immature teratoma associated with gliomatosis involving the peritoneum, lymph nodes and Douglas' pouch, where gliomatosis coexisted with endometriosis. As far as we know, only seven cases of GP have been reported as coexisting with endometriosis. Eight cases with mature glial tissue in the lymph nodes, i.e., nodal gliomatosis, have been published either in association with GP or in its absence. Metaplasia of pluripotent coelomic stem cells has been suggested to be responsible for the pathogenesis of endometriosis and GP rather than implantation metastases of ovarian teratomatous tumor with varying maturation. This theory is also applied to GP independently of ovarian teratomatous tumors. To the best of our knowledge, nodal gliomatosis coexisting with GP and also involving endometriosis has not yet been reported.

BACKGROUND: Adenoid cystic carcinoma (ACC) and adenoid basal carcinoma (ABC) are rare in the uterine cervix. ACC is more aggressive than ABC, thus accurate differential diagnosis is important. In this study, we identified cytologic features useful in distinguishing these two tumors for diagnosis. METHODS: Three cases of ACC and five cases of ABC were selected for this study. Cervicovaginal smear slides were reviewed retrospectively, and the area, circumference, major axis, and minor axis of nuclei were measured using an image analyzer. RESULTS: ACC displayed three-dimensional clusters with a small acini pattern. ABC displayed peripheral palisading without an acini pattern. The nuclei of ACC were more irregular and angulated than those of ABC, and the former showed a coarsely granular chromatin pattern. The nucleic area, circumference, major axis, and minor axis were 18.556+/-8.665 microm2, 23.320+/-11.412 microm, 5.664+/-1.537 microm, and 4.127+/-1.107 microm in ACC and 11.017+/-4.440 microm2, 15.920+/-5.664 microm, 4.612+/-1.025 microm, and 3.088+/-0.762 microm in the cases of ABC. All measured values showed statistically significant difference (p < .001). CONCLUSIONS: Although the nuclei of both of these tumor types were oval shaped, inferred from the ratio of minor axis to major axis (0.728 in ACC and 0.669 in ABC), the area of nuclei was approximately 1.7 times larger in ACC than in ABC. Distinguishing nucleic features, including area, morphology, and chromatin pattern, may be helpful in making a correct diagnosis.

A 61-year-old woman was referred to surgery for incidentally found colonic polyps during a health examination. Physical examination revealed widespread eczematous skin lesion without pruritus in the perianal and vulvar area. Abdominopelvic computed tomography showed an approximately 4-cm-sized, soft tissue lesion in the right perianal area. Inguinal lymph node dissection and Mils' operation extended to perianal and perivulvar skin was performed. Histologically, the anal canal lesion was composed of mucin-containing signet ring cells, which were similar to those found in Pagetoid skin lesions. It was diagnosed as an anal canal signet ring cell carcinoma (SRCC) with perianal and vulvar Pagetoid spread and bilateral inguinal lymph node metastasis. Anal canal SRCC is rare, and the current case is the third reported case in the English literature. Seven additional cases were retrieved from the world literature. Here, we describe this rare case of anal canal SRCC with perianal Pagetoid spread and provide a literature review.

BACKGROUND AND OBJECTIVES: Pulmonary embolism (PE) is a disease with high mortality if left untreated. But, confirmative diagnosis is difficult because many diagnostic modalities are nonspecific. Pulmonary angiography, which is considered as the gold standard diagnostic tool, is invasive, costly, time-consuming, and not always available in small centers. Echocardiography is a non-invasive and available in the emergency room without significant time delay. We investigated the role of echocardiography as a screening test in patients with suspected PE. MATERIALS AND METHODS: (A) Retrospective study: We analyzed the recorded videotapes of transthoracic echocardiography in fifty patients with confirmed PE from Jan 1995 to Aug 1999. From the frequent echocardiographic findings of those patients, positive criteria were defined as followed ( 2 among 1-5 or only 6). (1) RV or pulmonary artery dilatation (RVEDA/LVEDA 0.6) (2) RV hypokinesis (3) paradoxical septal wall motion (4) pulmonary hypertension (5) TR (moderate degree or more) (6) Visible thrombus. Although the degree of TR was less than moderate, if the degree of pulmonary hypertension was more than moderate, we considered as PE. (B) Prospective study: From Nov 1999 to June 2000, patients with suspected pulmonary embolism underwent a transthoracic echocardiography and perfusion-ventilation lung scan or chest CT. We assessed echocardiographic findings, sensitivity and specificity of the previously defined echocardiographic positive criteria for PE. RESULTS: (A) Retrospective study: The sensitivity of echocardiography for PE was 74%. (B) Prospective study: The number of enrolled patients was thirty-four. In twenty patients the diagnosis was PE. The sensitivity of echocardiography was 75% but the specificity was 14%. CONCLUSION: Echocardiography may be used as a good screening test in patients who are clinically suspicious of pulmonary embolism.

BACKGROUND AND OBJECTIVES: Heart rate variability(HRV) reflects the autonomic integration of heart. There were many reports that HRV in patients with myocardial infarction or heart failure is an independent prognostic factor to predict fatal arrhythmia and sudden cardiac death. But, the role of HRV is still controversial in stable angina patients without history of myocardial infarction. In this study, we tried to compare HRV indices between stable angina patients and normal subjects. MATERIALS AND METHODS: Twenty-one stable anginal patients without history of myocardial infarction (mean age : 57 +/- 2 years) and twenty-one relatively healthy persons without history of coronary heart disease (mean age : 53 +/- 2 years) were included in the study and underwent 24-hour ambulatory ECG monitoring. In patients group, all underwent coronary angiography after 24-hour ambulatory ECG monitoring. HRV was analyzed over the whole 24 hours, using time and frequency domain parameters, according to time phases and coronary angiographic severity. RESULTS: There were no significant differences in age, sex and cardiovascular risk factors, except hypertension (p=.001) between two groups. HRV indices such as rMSSD, pNN50, LF, HF, LFnorm and HFnorm were significantly decreased (p<0.05) in patients group. But the angiographic severity of coronary arteries did not show any significant effect on the HRV indices in patients group. CONCLUSIONS: We observed significantly reduced HRV indices in patients with stable angina without history of myocardial infarction.

Actinomyces meyeri is a Gram positive, strict anaerobic bacterium, which was first described by Meyer in 1911. Primary actinomycotic osteomyelitis is rare and primarily affects the cervicofacial region, including mandible. We present an unusual case of osteomyelitis of a long bone combined with myoabscess due to A. meyeri. A 70-year-old man was admitted for pain and pus discharge of the right elbow. Twenty-five days before admission, he had hit his elbow against a table. MRI of the elbow showed a partial tear of the distal triceps tendon and myositis. He underwent open debridement and partial bone resection for the osteomyelitis of the olecranon. Biopsy showed no sulfur granules, but acute and chronic osteomyelitis. The excised tissue grew A. meyeri and Peptoniphilus asaccharolyticus. Intravenous ceftriaxone was administered and switched to oral amoxicillin. Infection of the extremities of actinomycosis often poses diagnostic difficulties, but it should not be neglected even when the characteristic pathologic findings are not present.

Objective:
: Patients with mild ischemic stroke experience various sequela and residual symptoms, such as anxious behavior and deficits in movement. Few approaches have been proved to be effective and safe therapeutic approaches for patients with mild ischemic stroke by acute stroke. Sildenafil (SIL), a phosphodiesterase-5 inhibitor (PDE5i), is a known remedy for neurodegenerative disorders and vascular dementia through its angiogenesis and neurogenesis effects. In this study, we investigated the efficacy of PDE5i in the emotional and behavioral abnormalities in rats with mild ischemic stroke.
Methods:
: We divided the rats into four groups as follows (n=20, respectively) : group 1, naïve; group 2, middle cerebral artery occlusion (MCAo30); group 3, MCAo30+SIL-pre; and group 4, MCAo30+SIL-post. In the case of drug administration groups, single dose of PDE5i (sildenafil citrate, 20 mg/kg) was given at 30-minute before and after reperfusion of MCAo in rats. After surgery, we investigated and confirmed the therapeutic effect of sildenafil on histology, immunofluorescence, behavioral assays and neural oscillations.
Results:
: Sildenafil alleviated a neuronal loss and reduced the infarction volume. And results of behavior task and immunofluorescence shown possibility that anti-inflammation process and improve motor deficits sildenafil treatment after mild ischemic stroke. Furthermore, sildenafil treatment attenuated the alteration of theta-frequency rhythm in the CA1 region of the hippocampus, a known neural oscillatory marker for anxiety disorder in rodents, induced by mild ischemic stroke.
Conclusion
: PDE5i as effective therapeutic agents for anxiety and movement disorders and provide robust preclinical evidence to support the development and use of PDE5i for the treatment of mild ischemic stroke residual disorders.

Purpose:
Whether administering chemotherapy followed by tamoxifen plus a gonadotropin-releasing hormone (GnRH) agonist to treat patients with lower-risk hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer provides a greater benefit than administering tamoxifen plus GnRH agonist alone remains unclear. This study aimed to compare the outcomes of propensity score-matched (PSM) patients who underwent these 2 types of treatment plans.
Methods:
This retrospective study included patients treated at our institution between 2009 and 2019. Eligible patients had HR-positive, HER2-negative, invasive breast cancer who had undergone surgery. There were 579 patients with HR-positive, HER2-negative breast cancer who were treated with a GnRH agonist and tamoxifen; patients with pathologic N2 and those who received neoadjuvant chemotherapy were excluded. After 1:1 PSM of patients who underwent GnRH agonist treatment and tamoxifen with versus without chemotherapy, 122 patients from these 2 groups were analyzed. Survival rates were calculated using the Kaplan-Meier method and compared via the log-rank test.
Results:
After PSM, there were no significant differences in several baseline characteristics between the 2 groups. After a median follow-up of 62.8 months, the patients in both groups demonstrated similar outcomes with no significant difference in disease-free survival (P = 0.596).
Conclusion
Patients derived no significant survival benefit from undergoing a chemotherapy regimen before receiving tamoxifen and GnRH agonist therapy compared to forgoing such chemotherapy.
