Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossa. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present two cases of bilateral renal agenesis, one is diagnosed by ultrasonography after amnioinfusion at 24 weeks gestation, the other is diagnosed postnatally after term delivery.

Backgrounds: Thyroid hormones play a fundamental role in the initiation and maintenance of somatic growth in mammalian species, and the insulin-like growth factors(IGFs) occupy a position of central importance in the growth of all tissues. To evaluate the changes in serum insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding proteins in hyperthyroid and hypothyroid patients, sera was obtained from 19 hyperthyroid patients, 9 hypothyroid patients, and 10 healthy volunteers. Methods: IGF-I concentration was determined by radioimmunoassay, and changes in IGFBPs were assesed by Western Ligand Blotting. To evaluate the binding pattern of IGF-I & IGFBPs, autoradiographs were obtained. Results & Conclusion: IGF-I levels were increased significantly in hyperthyroid patients(mean ±SE, 267.88±9.80 ng/ml, p<0.05) and decreased significantly in hypothyroid patients(154.81±1.43 ng/ml, p<0.01) compaired to healthy control group(209.45±.60 ng/ml). Autoradiograph of serum IGFBPs from patients with hyperthyroidism and hypothyroidism did not show any change in the intensity of IGFBP-3 bands(40-45 KD) and IGFBP-1 bands, but in hyperthyroid patients, it showed increased intensity of IGFBP-2 band compared to healthy control group and hypothyroid patients.

The purpose of this study is to evaluate the flow ability of the thermoplasticized Gutta Percha in different temperatures. Four Gutta Percha products were classified by its hardness (soft, medium, and hard) and were experimented by the Rheometer (Melt flow indexer MFI-10, DAVENPORT, England) measuring apparatus, in (23 ± 2) ℃, and in a relative humidity of (50 ± 5) %, following the guidelines of ISO 1133-1:2011. The heating temperature ranged from 108℃, 160℃ to 200℃, and the load at 2.16 kg and 3.8 kg. The Gutta Percha was cut in 5 mm to be suitable for the rheometer pressurization process. After the experiment was conducted with a preheating time of 5 minutes, a cutting time of 5–240 seconds, and a sample of 10 grams, the Gutta Percha did not show any changes in fluidity for 108℃, 160℃, but showed a change in its flow ability in 200℃. Also, the Gutta Percha did not show any changes in its fluidity when it was pressurized by 2.16 and 3.8 kilograms. Therefore, this experiment shows that the heating temperature and the cut-off time showed a significance while measuring the melt flow rate.

Hiatal hernias are usually classified into three distinct types: type I, sliding hernias; type II, paraesophageal hernias; and type III, a combination of types I and II. Paraesophageal herniation is an uncommon disorder accounting for approximately 5% of all hernias at the esophageal hiatus. Laparoscopic repair of paraesophageal hernias is rapidly replacing the traditional open approach. However, several series have shown high recurrence rates due to the difficulty in closing the hiatal gap. A 28-year-old male patient presented with no symptoms including reflux symptom, but a herniation of the transverse colon and omentum into the thorax to the right side of the esophageal hiatus of the diaphragm was found. The anatomy of the stomach and small bowel loops were unremarkable. After reduction of the colon and omentum, the defect was closed and reinforced using Prolene mesh via a laparoscopic procedure. The patient recovered early, with no complication, and has been recurrence free during the 8 months of followed up.

BACKGROUND: The aim of this study was to establish the incidence, predictive factors, characteristics, and clinical outcomes of acute symptomatic seizures (ASS) after acute ischemic stroke (AIS). METHODS: In total, 2,528 consecutive patients with first-ever AIS were included. Patients with a history of epilepsy or provoked seizures due to tumor, head trauma, brain surgery, or high fever were excluded. Onset seizure (OS) and ASS were defined as seizures occurring within 24 hours and 7 days after AIS, respectively. The incidence of ASS, type of seizures, presence of late unprovoked seizure (LUS), MRI, and electroencephalogram were analyzed. RESULTS: ASS and OS occurred in 23 patients (0.9%) and 15 patients (0.6%), respectively; 20 of the patients with ASS (87.0%) had partial seizures and 4 (17.4%) developed status epilepticus. The incidence rates of ASS were 1.3%, 0.3%, and 0.2% in AIS caused by large-artery atherosclerosis, small-vessel occlusion, and cardioembolism, respectively. Of the 23 patients with ASS, the cortex was involved in 19 (82.6%), 16 patients (69.6%) had medium-sized to large lesions, the anterior circulation territory was involved in 21 patients (91.3%), and 4 patients (17.4%) developed MRI-confirmed hemorrhagic transformation of the lesions. Epileptiform discharges were observed in 9 (45%) of the 20 patients with ASS. Three of the 23 patients with ASS (13.0%) developed LUS. CONCLUSIONS: The incidence of ASS was 0.9% and was highest in the large-artery atherosclerosis group. The development of ASS was significantly associated with cortical involvement, medium-sized to large lesions, and lesions in the anterior circulation territory. Three of 23 patients (13%) developed LUS.

A 77-year-old man developed diplopia, gait ataxia, and paresthesia. A clinical examination also revealed ophthalmoplegia, facial palsy, ataxia of the limbs and trunk, and reduced deep tender reflexes. Laboratory and electrophysiological studies revealed albuminocytological dissociation and demyelination. He was diagnosed as Miller-Fisher syndrome and received intravenous immunoglobulin therapy. His clinical symptoms deteriorated at 12 weeks after onset. We diagnosed acute-onset chronic inflammatory demyelinating polyradiculoneuropathy, and which the patient recovered from following corticosteroid therapy.

PURPOSE: This study was done to know the usefulness of fractal analysis when evaluating the radiologic changes after decompression on jaw bone cystic lesions using fractal analysis. MATERIALS AND METHODS: 30cases of cystic lesions were followed up after decompression. Panoramic image was used to observe radiologic changes around the cystic lesion. The part of the panoramic image which showed radiologic change was defined as region of interest(ROI); The fractal dimension of the ROI was calculated using box-counting method. RESULTS: Using sign-rank test, there was a statistically significant difference in fractal dimensions after decompression therapy(P<;0.0001). The fractal dimensions statistically increased after decompression(the median of D:0.12). CONCLUSIONS: The ROI after decompression showed higher fractal dimensions which offer the objective proof of the bone healing around cystic lesions after decompression treatment.

A 13-year-old girl presented in our unit with progressive alopecia and a long history of edematous scalp in the occiput. Biopsy specimen of a lesion showed two-type pathologic abnormality consisting of diffuse neurofibroma in the lower portion and trichotillomania in the upper portion. Since the tumor spread diffusely through the lower dermis and subcutaneous fat tissue without destroying surrounding structures, we concluded that the trichotillomania might result from repetitive scratching or other traumatic behavior at the same site of underlying diffuse nerurofibroma. We reported a case of the concomitant occurrence of trichotillomania associated with diffuse neurofibroma.
