PURPOSE: We report a case of a scleral perforation during inferior rectus recession in congenital fibrosis of extraocular muscles and the management of this perforation with a scleral patch graft. CASE SUMMARY: A 20-month-old female with bilateral ptosis, absence of elevation and a chin-up position was diagnosed with congenital fibrosis of extraocular muscles. Because severe esotropia in the downward gaze was observed, we first performed esotropia surgery. After 1 year, she underwent a bilateral ptosis correction. We decided to perform bilateral inferior rectus recession due to an abnormal head posture and the absence of elevation. Because the inferior rectus muscles were extremely tight and adhered to the sclera, hooking and isolating these muscles during surgery was difficult. After muscle suture placement, a portion of the sclera that contacted the left inferior rectus was chipped off as this muscle was disinserted with blunt Westcott scissors. A scleral perforation was observed, thus, we placed a scleral patch graft using the donor sclera and finished the bilateral inferior rectus recession. No abnormal findings for the vitreous or retina were detected. At 8 months after surgery, the patient exhibited exotropia of 12 prism diopters in her primary gaze. Her abnormal head posture nearly disappeared. CONCLUSIONS: Careful isolation and disinsertion of the muscle from the globe is necessary in the treatment of patients who are expected to exhibit severe adhesions between the muscle and sclera, such as patients with congenital fibrosis of extraocular muscles.

PURPOSE: Gastrointestinal stromal tumors (GISTs) represent a distinct and the most important subset of, mesenchymal tumors of the GI tract. Stromal tumors of the gastrointestinal tract have long been a source of confusion and controversy, with regard to their classification, differentiation, criteria of malignancy and prognostic features. METHODS: The 26 case studies of patients treated for a Gastrointestinal mesenchymal tumor, including leiomyomas, leiomyosarcomas and GISTs, between 1994 and 2002 at Keimyung University Hospital, were evaluated retrospectively. The cases were confirmed as leiomyomas, schwannomas, or GISTs by pathological re-examination. 20 of the cases were diagnosed as GISTs, from the pathological examination, and were chosen for the evaluation of their clinicopathological and immunohistochemical characteristics, using CD34, CD117, alpha-SMA and S-100 done. RESULTS: The new diagnoses of the mesenchymal tumors were a leiomyoma in 3 cases, a schwannoma in 3 and gastric stromal tumors in all 20. The immunohistochemical studies were positive for CD117 and CD34 in 95 and 75% of the gastric stromal tumors, respectively. The histopathological findings showed 5 benign tumors, 3 borderline tumors, and 12 malignant tumors in the 20 patients. CONCLUSION: The immunohistochemical marker (CD117) for KIT is a specific marker for GISTs among the tumors occurring in the stomach, and can be used to distinguish GISTs from true leiomyomas and gastric schwannomas. We also found that severe cellularity, atypism, intratumoral hemorrhage and necrosis, large size and a high mitotic count correlate with malignant behaviour and a poor prognosis.

Vascular malformations in extremities are difficult to detect in cases of minor trauma. The authors report a case of an arteriovenous malformation (AVM) incidentally found by ultrasonography in a contusion. After a slip down, a 52-year-old man who had undergone total arthroplasty in both hips 10 years earlier complained of an ovoid right hip swelling that had gradually increased in size. Suspecting a simple cyst or hematoma, the swelling was examined by ultrasonography, which revealed a subcutaneous hematoma with arterial flow connected to muscle. Arteriography revealed an AVM around the right hip joint. Due to the presence of multiple arteriovenous shunts, a conservative treatment course was adopted and after 3 weeks of treatment the swelling almost completely resolved. It appears that the small AVM may have existed congenitally before hip surgery and the contusion over the AVM had led to hematoma rather than an arteriovenous fistula. The authors emphasize the usefulness of ultrasonography for the diagnosis of posttraumatic swelling.

Most adenocarcinomas of the colorectum arise in a visible benign precursor lesion, the adenoma, which is a monoclonal proliferation of dysplastic nonmalignant epithelial cells. Adenoma-adenocarcinoma sequence has been represented as the predominat pathogenetic pathway. But a small flat depressed colon cancer is characterized by non-polypoid growth pattem with no association of adenomatous tissues, which has tendency to early submucosal invasion and lymph node metastasis even in very small lesion (<10 mm). It supports de novo carcinogenesis of colorectal cancer, although most colorectal cancerarise in pre-existing adenoma. We report a case of small float colon adenocarcinoma arising in normal colonic epithelium rather than adenomatous polyp in familial adenomatous polyposis syndrome.

PURPOSE: Recent studies show that chorioamnionitis has an important role in the pathogenesis of bronchopulmonary dysplasia(BPD) and it induces thymic involution. The purpose of this study is to test the usefulness of thymic size at birth as a predictor of BPD. METHODS: This study was conducted on 91 very low birth weight infants of <1, 500 g with mean gestational age of 29.3 weeks and mean birth weight of 1, 161 g who were admitted at NICU of Dong Kang General Hospital for past 4 years of whom 21 infants had BPD. Thymic size was measured on routine chest radiographs taken in the first 3 hours after birth and measured as the ratio between the width of the cardiothymic shadow at the level of the carina and that of the thorax at the costophrenic angles (CT/ T). RESULTS: Correlation of thymic size with gestational age was statistically significant (P=0.003). CT/T of BPD group was smaller than that of non-BPD group (0.27+/-0.06, 0.33+/-0.07, respectively, P<0.01). A significant positive correlation between small thymus at birth and BPD was detected (P=0.003, odds ratio, 21.7), but not in other disease groups. CONCLUSIONS: We concluded that a small thymus at birth on the chest radiograph could be used as an early predictive parameter of the BPD.

Hypoglossal nerve palsy after general anesthesia is an exceptionally rare complication, which has varied etiology. We present a case of unilateral hypoglossal nerve palsy resulting from repeated airway intervention for general anesthesia. A 57-year-old woman was scheduled to undergo modified radical mastectomy. During endotracheal intubation, the patient had Cormack's grade III-a severe airway condition. After the first intubation attempt failed, the intubation was attempted a second time using a stylet inside the endotracheal tube with cricoid pressure; this attempt was successful. In the evening of the operation day, the patient complained of dysarthria and dysphagia. Physical examination revealed deviation of the tongue to the right, which may have been caused by traumatic hypoglossal nerve injury. This case reviews the pathophysiology, prevention, and management of hypoglossal nerve palsy.

PURPOSE: The authors evaluated the relationships between the clinical factors and resistive indexes (RIs) of prostate and urethral blood flows by using power Doppler transrectal ultrasonography (PDUS) in men with benign prostatic hyperplasia (BPH). METHODS: The data of 110 patients with BPH and lower urinary tract symptoms (LUTS) treated between January 2015 and July 2015 were prospectively collected. PDUS was used to identify the capsular and urethral arteries of the prostate in order to measure RIs. International Prostate Symptom Score (IPSS), maximal flow rate (Qmax), total prostate volume (TPV), transition zone volume (TZV), transition zone index (=TZV/TPV), presence of intravesical prostatic protrusion (IPP), and the RIs of capsular and urethral arteries were evaluated for all of the patients by one urologist. RESULTS: The 110 patients were categorized according to IPSS (mild symptoms, 0-7; moderate symptoms, 8-19; and severe symptoms, 20-35), Qmax (<10 and ≥10 mL/sec), TPV (<30 and ≥30 mL), and presence or absence of IPP. No significant relationship was found between the mean RI of any artery and IPSS or Qmax. The mean RIs of the urethral artery, and left and right capsular arteries were significantly dependent on prostate size and the presence of IPP. CONCLUSIONS: RI obtained by using PDUS correlated with the presence of IPP and prostate size. The RI of prostate blood flow can be used as a noninvasive diagnostic tool for BPH with LUTS.

Cutaneous larva migrans (CLM) is a rare serpiginous cutaneous eruption caused by accidental penetration and migration in the skin with infective larvae of nematode that normally do not have the human as their host. Although CLM has a worldwide distribution, the infection is most frequent in warmer climates. More recently, they have been increasingly imported from the tropics or subtropics by travelers. We experienced two patients who had pruritic serpiginous linear eruption in their skin for a few weeks after traveling to the endemic areas (Brazil and Thailand, respectively). After the treatment with albendazole, the skin lesions resolved with post-inflammatory hyperpigmentation. We report herein two cases of cutaneous larva migrans successfully treated with albendazole.
