Neoplasms of the nasophrynx are rare in neonates and infants. The most common nasopharyngeal tumor encountered in this age group is teratoma-neoplasm containing multiple heterotopic tissues. Four histologic types of nasopharyngeal teratoma occur-dermoid, teratoid, true teratoma, epignathiof which dermoid is most frequently seen. We have experienced a case of nasopharyngeal teratoma in a female neonate with signs and symptoms of upper airway obstruction. It was diagnosed by cervical. CT and confirmed as ture teratoma by histological examination. Nesopharyngeal teratoma was removed by contact Nd:YAG laser. In addition, we briefly reviewed the literature of neonatal nasopharyngeal teratoma.

Cryptococcosis is an acute, subacute or chronic infectian caused by the encap sulated yeast Cryptococcus neoformans. The case of Cryptococcosis is a 2 5/12 year-old boy with involvement of the skin, lungs, liver, spleen, lymph node and central nervous system is reported. He has suffered from fever, nausea., vomiting and multiple skin lesions for a month. Thcre were various cutaneous lesions consisting of papules, pustules, nodules, crusts and ulcers on the scalp, face, back, buttocks and both extremities. Diagnosis was confirmed by the clinical characteristics, histopathologic findings and culture of the C. neoformans from cerebrospinal fluid and marcerated skin tissue. He was successfully treated with combination of Amphotericin B and 5-fluorocytosine.

PURPOSE: We tried to identify the factors associated with intracranial hemorrhage (ICH) in patients with acute brain infarction receiving a tissue plasminogen activator. We assumed that ICH is increased if intracranial pressure has been increased in brain infarction patients who underwent IV thrombolysis. In this study, we selected the optic nerve sheath diameter (ONSD) in a way that intracranial pressure (ICP) measurement. ONSD measurements were compared with the occurrence of brain hemorrhage. METHODS: This study was a retrospective analysis of data acquired between January 2013 and December 2015. We included 100 acute brain infarction patients who received brain MRI and underwent IV thrombolysis in the emergency department. The ONSD measurements were taken with MRI in the axial view and compared with the occurrence of brain hemorrhage. The factors contributing to ICH in patients with thrombolysis was analyzed by a binary logistic regression analysis. Receiver operating characteristic (ROC) curves were used to find the cut-off value of ONSD that maximized the sum of the sensitivity and specificity. Statistical analysis was performed using SPSS 20.0. RESULTS: The mean ONSD for patients without ICH was 5.50±0.57 mm, and for those with ICH was 5.97±0.54 mm. ONSD in the ICH group were significantly larger than in the non-ICH group (5.50±0.57 versus 5.97±0.54). CONCLUSION: ONSD in acute brain infarction patients who underwent IV thrombolysis is useful in the assessment of ICH risk.

Pneumothorax, pneumomediastinum and pneumopericardium usually develop during emergency situations and these conditions may result in cardiopulmonary compromise, so an early and accurate diagnosis is seen as crucial for proper treatment. For diagnosis of pneumothorax, pneumomediastinum and pneumopericardium, chest radiography is a primary modality and CT can help for diagnosing them earlier and detecting associated abnormalities. The purpose of this pictorial essay is to describe the pathophysiology, various radiographic signs and diagnostic pitfalls of pneumothorax, pneumomediastinum and peumopericardium on chest radiographs that are correlated with CTs, and to aid the physician in the radiographic diagnosis.

Etoposide is a semi-synthetic podophyllotoxin that binds to microtubular proteins to inhibit cell division. It has been used extensively in the treatment of both solid and hematologic malignancies. Chemotherapy-induced acral erythema is a distinctive syndrome of painful, symmetric, well-defined swelling and erythema of the palms and soles seen in patients receiving high-dose chemotherapy. It occurs most commonly with fluorouracil, doxorubicin, and especially cytosine arabinoside. Although etoposide, mercaptopurine and methotrexate have also been implicated. Here we report a case of acral erythema induced by etoposide in a 15-year-old child with neuroblastoma.

The primary malignant tumor of the peritoneum also known as primary peritoneal carcinoma or primary peritoneal papillary serous carcinoma is rare and involves the peritoneum, especially the pelvic peritoneum of female patients. It is difficult to differentiate histologically between papillary mesothelioma, primary ovarian tumor and primary peritoneal carcinoma. We report two cases of the primary peritoneal carcinoma with clinical presentation and histologic characteristics.

Most gastric candida infections have been reported in immune-insufficient patients with peptic ulcer, but there have been few reports on gastric candidiasis with malignant ulcer in the stomach. We experienced a case of candida infection with gastric carcinoma in a 72-year-old female with diabetic mellitus. The endoscopic view showed multiple whitish necrotic plaques with a huge ulcer in the body of the stomach. The pathologic findings showed that budding yeast and pseudohyphae had infiltrated through the ulcerated stomach wall and the stomach wall contained tubular adenocarcinoma. After treatment with Fluconazole medication for 14 days, the patient underwent total gastrectomy along with D2 lymph node dissection. For the final pathologic results, there was no evidence of any remnant candidiasis, and the patient was discharged without specific complications. Through our experience and with reviewing articles about gastric candidiasis, we recommend that the gastric candidiasis that is accompanied with gastric malignancy should be treated before administering definite treatments for the gastric cancer.

PURPOSE: The aim of this study was to compare the short-term operative outcomes of laparoscopy-assisted total gastrectomy (LATG) with those of open total gastrectomy (OTG) for patients suffering with advanced upper gastric cancer. MATERIALS AND METHODS: Of the 47 patients who underwent LATG with D1+beta or D2 lymphadenectomy from July 2004 to March 2008, 29 patients with pathologically proven advanced gastric cancer were compared with 35 patients who underwent conventional OTG during the same time period. The comparison was based on the clinicopathological characteristics, the surgical outcome, the follow-up survival and tumor recurrence. RESULTS: The patients' age, gender and body mass index were similar between the two groups. However, there were statistically differences in tumor size (9.2+/-3.9 vs 6.1+/-3.6 cm, P=0.002) and the proximal resected margin (2.1+/-2.0 vs 3.6+/-2.1 cm P=0.004). There was no significant difference in most of the peri- and post-operative courses such as the time to first flatus, the time to starting a solid diet and the length of the hospital stay, except for a longer operating time (289.0 vs. 361.3 minutes, P<0.001) in the LATG group. The complication rate was higher in the LATG group (13.8%) than that in the OTG group (5.7%). The mean overall survival and disease free survival times were 32 and 31 months, and 24 and 28 months, respectively, with an average 18.8 months follow-up duration. The main recurrent sites were peritoneum and lymph node in both groups. CONCLUSION: The early results of the current study suggest that LATG for AGC is technically feasible and it does not show any inferiorities of the postoperative outcomes as compared to those of conventional open total gastrectomy.

Journal of Neurogastroenterology and Motility 2022;28(2):231-236
Background/Aims:
Food retention, which is a characteristic observed in patients with achalasia, can interfere with peroral endoscopic myotomy (POEM).However, there is no established guideline for esophageal preparation for POEM. A previous study has shown that drinking warmwater may reduce the lower esophageal sphincter pressure in patients with achalasia. This study aims to evaluate the possibility ofproper preparation of POEM by instructing the patient to drink warm water.
Methods:
The warm water preparation was performed in 29 patients with achalasia who underwent POEM. The patients drank 1 L of warm water (60 o C) the night before POEM. We evaluated the esophageal clearness and determined the preparation quality. Twenty-nine patients were prospectively recruited and compared to control group. The control cohort comprised achalasia patients whoseendoscopic image was available from the achalasia database of our institution. A 1:2 propensity score-matched control cohort was established from the database of achalasia subjects (n = 155) to compare the outcome of the preparation.
Results:
In the warm water preparation group, only 1 patient (3.4%) had some solid retention, but it did not interfere with the POEM procedure. The grade of clearness (P = 0.016) and quality of preparation (P < 0.001) were significantly better in the warm water preparation group than in the matched control group. There was no any adverse event at all related to warm water preparation protocol.
Conclusions
Drinking warm water dramatically reduces esophageal food retention and significantly improves the quality of esophageal preparation.This simple protocol is quite useful, safe, and cost-effective in the preparation of achalasia patients for POEM.

Objectives:
This study aimed to assess the antibacterial, bactericidal, and mouth freshener effects of lysozyme hydrochloride 0.01%, sodium fluoride 0.02%, and cetylpyridinium chloride 0.05%.
Methods:
Eight oral disease-related bacteria were cultivated anaerobically. Four samples were prepared with or without 0.5% cetylpyridinium chloride, 0.2% sodium fluoride, and 0.1% lysozyme hydrochloride. Antimicrobial activity was tested in 96-well microplates. After assessing the bacterial count, the bacterial suspension was mixed with samples and spread on agar. The bactericidal rate was calculated by counting and comparing treated and untreated colonies.
Results:
Lysozyme hydrochloride 0.01%, sodium fluoride 0.02%, and cetylpyridinium chloride 0.05% mouth fresheners sterilized 99.99% of 8 oral bacteria, including Streprococcus mutans. Lysozyme hydrochloride 0.01%, sodium fluoride 0.02%, and cetylpyridinium chloride 0.05% mouth fresheners showed 99.97% bactericidal activity against Lactobacillus acidophilus.
Conclusions
Lysozyme hydrochloride 0.01%, sodium fluoride 0.02%, and cetylpyridinium chloride 0.05% mouth fresheners confirmed the sterilization and antibacterial effects on oral disease-causing bacteria.
