Intramuscular injection(IM) into the gluteal muscles is a common route of medication, but may lead to complications. A retrospective review of 32 patients who required surgical treatment for local complications of buttock injections in children was made at the Taegu Fatima Hospital during a seven-year nine-month period (March 1990 to December 1997). Local complications included acute inflammation, cellulitis and abscess(71.9 %), and fat necrosis(21.9 %), and injection granuloma(6.2 %). Over the half of injections were on the upper and outer quadrant of the buttock, but the other 43.7 % were in the upper and inner or lower and outer quadrant which are considered unsuitable sites for intramuscular injection. The majority of complications developed within fat tissue(90.6 %) rather than within muscle(9.4 %). Two-thirds of the patients were under 2 years of age, this suggests that it is technically difficult to accurately administer IM injections in small children because muscle mass is smaller compared to subcutaneous. In addition subcutaneous fat is more susceptible to chemical irritation. Staph. aureus was the predominant organism, isolated in 84.6 % of the patients with abscesses. Treatment consisted of needle aspiration, incision and drainage, curettage, or surgical excision. In conclusion, the major factor that contributes to complications following IM of the buttock appears to be the inadvertent intrafat rather than of IM injection. Accurate injection into the muscles based on a knowledge of pelvic anatomy as well as the potential complications is necessary to prevent complications.

Objective : The purpose of this pilot study was to examine the safety and function of the newly developed cerebrospinal fluid (CSF) reservoir called the V-Port. Methods : The newly developed V-Port consists of a non-collapsible reservoir outlined with a titanium cage and a connector for the ventricular catheter to be assembled. It is designed to be better palpated and more durable to multiple punctures than the Ommaya reservoir. A total of nine patients diagnosed with leptomeningeal carcinomatosis were selected for V-Port insertion. Each patient was followed up for evaluation for a month after the operation. Results : The average operation time for V-Port insertion was 42 minutes and the average incision size was 6.6 cm. The surgical technique of V-Port insertion was found to be intuitive by all neurosurgeons who participated in the pilot study. There was no obstruction or leakage of the V-Port during intrathecal chemotherapy or CSF drainage. Also, there were no complications including post-operative intracerebral hemorrhage, infection and skin problems related to the V-Port. Conclusion : V-Port is a safe and an easy to use implantable CSF reservoir that addresses problems of other implantable CSF reservoirs. Further multicenter clinical trial is needed to prove the safety and the function of the V-Port.

Trichilemmal cysts are common fluid-filled growths that arise from the isthmus of the hair follicle. They can form rapidly multiplying trichilemmal tumors-, also called proliferating trichilemmal cysts, which are typically benign. Rarely, proliferating trichilemmal cysts can become cancerous. Here we report the case of a patient who experienced this series of changes. The 27-year-old male patient had been observed to have a $1{\times}1cm$ cyst 7 years ago. Eight months prior to presentation at our institution, incision and drainage was performed at his local clinic. However, the size of the mass had gradually increased. At our clinic, he presented with a $5{\times}4cm$ hard mass that had recurred on the posterior side of his neck. The tumor was removed without safety margin, and the skin defect was covered with a split-thickness skin graft. The pathologic diagnosis was a benign proliferating trichilemmal cyst. The mass recurred after 4months, at which point, a wide excision (1.3-cm safety margin) and split-thickness skin graft were performed. The biopsy revealed a trichilemmal carcinoma arising from a proliferating trichilemmal cyst. This clinical experience suggests that clinicians should consider the possibility of malignant changes when diagnosing and treating trichilemmal cysts.

We report the case of a 68-year-old man with a stromal tumor of uncertain malignant potential (STUMP), which had metastasized to the lung. The patient complained of an enlarged mass in the anterior chest. Chest computed tomography (CT) showed a sternal abscess with multiple nodules in both lungs. A thoracoscopic lung biopsy of the nodules and incision/drainage of the sternal mass were performed simultaneously. CT of the pelvis revealed an enlarged prostate with irregular cystic lesions in the pelvis. Prostate biopsy was done and demonstrated hypercellular stroma with minimal cytological atypia, a distinct pattern of STUMP. The sternal abscess proved to be tuberculosis and the lung lesion was consistent with STUMP, which had spread from the prostate. However, to our knowledge, the tuberculous abscess might not be assoicated with STUMP in the lung. The patient refused surgical prostatectomy and was discharged with anti-tuberculosis medication. On one-year follow up, the patient had no evidence of disease progression.

Hyperventilation is defined as ventilation in excess of that required to maintain normal blood $PaO_2$ and $PaCO_2$. It is produced by several distinct causes: anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The dental fears about acute pain, needle, drill and dental surgery lead to the severe anxiety and increased blood catecholamine level. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the gentle care, two cases of hyperventilation were occurred during local anesthesia for incision and drainage of acute odontogenic infectious lesions. We suggest that the dental patients with acute odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.

The appropriate care to the dental emergency patients is much important in the aspect of community dental service. To attain such a purpose, the sacred duty of the training of oral and maxillofacial surgeons is required. So, a retrospective study on the characteristics of dental injuries and diseases in emergency care unit will be very meaningful. This study was carried by reviewing the charts and radiographic films of 3,394 patients, treated for dental emergency at Wonju Christian Hospital, Republic of Korea, from January 1, 1993 to December 31, 2002. All patients were classified to 6 groups including trauma, toothache, infection, hemorrhage, TMJ disorder and the others. The clinical characteristics of diseases and treatment modalities according to each group were analyzed. The trauma (73.9%) was the most frequent cause in dental emergency patients, and acute toothache, odontogenic infection, oral hemorrhage, and TMJ disorder were next in order. Gender prediction was male (68%), there were many patients on May and December in the monthly frequency, and the most frequent age group was from 0 to 9 years. In the trauma group, male (68.6%) was predominant, and soft tissue injuries and primary closures were the most frequent type of injury and treatment. In jaw fractures, traffic accidents were the most cause and the weakest site was mandibular symphysis area, and mandibular angle, condyle, and body area were next in order. In the acute toothache group, the cause was dental pulpitis mostly and treatment for that was drug administration mainly. Buccal space abscess in infection group had the largest incidence (24.5%), and common treatments were incision and drainage and medications. In the hemorrhage group, a major cause was postoperative bleeding (60.3%) and hemostasis was obtained by pressure dressing, curettage and suture. For the TMJ disorder group, the peak incidence (63.8%) was shown in the post-traumatic myofascial pain dysfunction syndrome and its primary care was medication such as analgesics and sedatives. In the other group, the various specific symptoms were complained due to acute sialadenitis, trigeminal neuralgia, acute stomatitis, chemical burn, terminal stage neuritis of head and neck cancer, and foreign body aspiration. In conclusion, for the rapid and proper care of the emergency dental diseases, well-trained education should be presented to the intern and resident course of oral and maxillofacial surgery. And it is demanded that oral and maxillofacial surgeons must be prepared in knowledge and skill for such emergency care.

Metallic bone plates and screws have been commonly used in oral and maxillofacial surgery for internal fixation. However, there are several disadvantages such as atrophy of cortical bone inherent to excessive rigid fixation systems, growth disturbance in growing individual, allergy reaction, interference with radiographic imaging, palpability, thermal sensitibity and the need for subsequent removal. To overcome these disadvantages and avoid additional surgery of removal of plates and screws, there have been many studies of biodegradable plates and screws. But, It also has complication such as foreign body reactions. We have undertaken a clinical and retrospective study on 140 patients in Dept. of Oral and Maxillofacial Surgery, Inha University Hospital from February 2006 to March 2009. The purpose of this study is to report the clinical cases and review of the literatures with biodegradable plates and screws. And we concluded following results. 1. 6 cases(3.4%) of the 177 operation sites(140 patients) experienced complications. 1 case(0.6%) was a failure of initial fixation, 1 case(0.6%) was a postoperative infection, 4 cases(2.3%) were inflammations or foreign body reaction. 2. Postoperative infections, inflammations and foreign body reactions were completely recovered with incision and drainage, supporative care with antibiotic coverage and removal of biodegradable plates. 3. Biodegradable plates and screws provide acceptable rigidity and stability clinically. But, long-term observation is required for the tissue reactions around the biodegradable plates and screws because of long resorption periods of the biodegradable materials.
