Performing rhinoplasty using filler injections, which improve facial wrinkles or soft tissues, is relatively inexpensive. However, intravascular filler injections can cause severe complications, such as skin necrosis and visual loss. We describe a case of blepharoptosis and skin necrosis caused by augmentation rhinoplasty and we discuss the patient's clinical progress. We describe the case of a 25-year-old female patient who experienced severe pain, blepharoptosis, and decreased visual acuity immediately after receiving a filler injection. Our case suggests that surgeons should be aware of nasal vascularity before performing an operation, and that they should avoid injecting fillers at a high pressure and/or in excessive amounts. Additionally, filler injections should be stopped if the patient complains of severe pain, and appropriate measures should be taken to prevent complications caused by intravascular filler injections.

Intravascular papillary endothelial hyperplasia (IPEH) has appeared in the literature under a variety of names, including Masson's tumor, Masson's hemangioma, and Masson's pseudoangiosarcoma. It is a benign lesion of the skin and subcutaneous tissue characterized by reactive proliferation of vascular endothelial cells with papillary formations. The clinical picture is not specific and the lesion resembles malignant angiosarcoma clinically and histopathologically. Therefore, it is often mistaken for angiosarcoma and a group of other benign and malignant vascular lesions. We report on a case of IPEH adherent to peripheral nerve treated with operative excision.

A micro syringe which can be attached to the end of a micro intravascular endoscope for drug injection is fabricated and its characteristic is tested. The syringe consists of a drug chamber and an actuator chamber which are separated by a silicone rubber membrane. The drug chamber is filled with liquid drug by the membrance actuation caused by the vaporization and condensation of the working liquid in the actuator chamber. The liquid drug is ejected by the electrolysis of the working liquid. The membrane deflection by each actuation method has been measured. The liquid ejection image has been captured during the electrolysis of the electrolyte. Also, the successful operation of the micro syringe under the normal blood pressure was verified.

조영제 사용으로 유발된 중증 저나트륨혈증이 일어난 경우는 매우 드물다. 저자들은 조영제를 사용한 복부전산화단층촬영을 시행했던 환아에서 중증 저나트륨혈증과 경련이 발생하였으나, 신경학적 검사에서 특별한 이상이 발견되지 않았고, 조영제 이외의 저나트륨혈증의 다른 원인을 발견할 수 없었던 환자를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Subcutanous hemangiosarcoma is rare malignant condition in dogs. An eleven-year-old neutered male Maltese was presented with multicentric cutaneous hemorrhagic nodules followed by lethargy. The patient showed regenerative anemia and thrombocytopenia with skyrocketing D-dimer, indicating that he had disseminated intravascular coagulation (DIC) on progress. Fine needle aspiration, histopathology, X-ray, and computed tomographic scanning ultimately diagnosed this patient as subcutaneous hemangiosarcoma with disseminated metastasis to the body. Unfortunately, the dog died due to side effects of anti-thrombotic therapy for DIC. This case report described a rare subcutaneous hemangiosarcoma in a Maltese dog.

Background: Caudal epidural injections have been commonly performed in patients with low back pain and radiculopathy. Although caudal injection has generally been accepted as a safe procedure, serious complications such as inadvertent intravascular injection and dural puncture can occur. The present prospective study was designed to investigate the influence of the depth of the inserted needle on the success rate of caudal epidural blocks. Methods: A total of 49 adults scheduled to receive caudal epidural injections were randomly divided into 2 groups: Group 1 to receive the caudal injection through a conventional method, i.e., caudal injection after advancement of the needle 1 cm into the sacral canal (n = 25), and Group 2 to receive the injection through a new method, i.e., injection right after penetrating the sacrococcygeal ligament (n = 24). Ultrasound was used to identify the sacral hiatus and to achieve accurate needle placement according to the allocated groups. Contrast dyed fluoroscopy was obtained to evaluate the epidural spread of injected materials and to monitor the possible complications. Results: The success rates of the caudal injections were 68.0% in Group 1 and 95.8% in Group 2 (P = 0.023). The incidences of intravascular injections were 24.0% in Group 1 and 0% in Group 2 (P = 0.022). No intrathecal injection was found in either of the two groups. Conclusions: The new caudal epidural injection technique tested in this study is a reliable alternative, with a higher success rate and lower risk of accidental intravascular injection than the conventional technique.

Purpose: Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's pseudoangiosarcoma, is a rare disease which is now considered as a reactive process of the endothelium rather than a benign neoplasm. It can occur in any blood vessels in the body but more common in the head and neck region as a solitary, often tender, bluish or reddish nodule. IPEH is characterized by the development of endothelial-lined papillary projections in a vascular lumen, usually associated with thrombotic material, the endothelial cells in the papillary structures showing only slight atypia and occasional mitotic Figures, the absence of tissue necrosis. Methods: 8 patients with IPEH were enrolled in the study from 2002 to 2007. All 8 lesions were surgically excised for histopathologic diagnosis. Results: 4 patients were female. The duration of the lesions ranged from 3 months to 15 years. The tumors were first noted between the ages of 20 and 72 years. 4 patients had lesions on the head; 2 on the toe; 1 on the back; and 1 on the finger, respectively. All lesions were solitary, ranged in size from 2 mm to 27 mm. There were no recurrences. Conclusion: The clinical appearance of IPEH is not specific, presented as a primary neoplasm, and the diagnosis can be established by microscopic examination. Complete surgical excision is the best choice of therapy for patients with IPEH, and is both diagnostic and curative. Awareness of this lesion will prevent incorrect diagnosis and overly aggressive treatment.
