Sternoclavicular joint posterior dislocations are considered a very uncommon, and type of injury where if esophagus or airway injury occurs behind the clavicle, it poses a high risk to the patient. In addition, if epiphyseal fracture occurs as a result of the sternoclavicular joint posterior dislocation, surgical treatment is often required. However, in the absence of a complete ossification of the clavicle, it is difficult to differentiate between a simple dislocation and epiphyseal fracture-dislocation solely based on simple radiographs or computed tomography scans. In this case report, the authors present a case in which a sternoclavicular joint posterior dislocation was diagnosed in a 14-year-old male athlete. The case report discusses how the posterior dislocation without epiphyseal fracture was diagnosed using an ultrasound and subsequently treated with successful outcomes using manual reduction. The case report presents our findings along with discussion that includes a literature review of relevant research.

Neurilemmomas of the trachea are extremely rare. The most common site of them is the distal third of the trachea and the age of the patients at presentation varied from 6 to 78 years old. They usually have a freqeuntly very long natural history, causing symptoms only after they have attained a considerable size. We experienced a case of near-total obstruction of the trachea by an intraluminal sessile neurilemmoma. The patient was a 66-year-old man with 2-year history of progressive exertional dyspnea and had several episodes of pneumonitis associated with productive cough. Grossly, the tumor was a well-circumscribed mass. Microscopically, typical cellular Antoni A and myxoid Antoni B areas were revealed.

We have treated 4-year-old with amikacin and rifampin, who suffered from bacterial meningitis due to gentamicin-resistant Pseudomonas aeruginosa. There was no complication during treatment. Even though we didint check audiometry and BUN and/or creatinine, urinalysis was normal and physical examination revealed no abnormalities. He had been treated fora about 3 months with various antibiotics including gentamicin, intravascular and intrathecal, and carbenicillin. Fever, headache and meningeal irritation signs recurred intermittently in spite of continuous treatment. The culture of the CSF showed P. aeruginosa, which initially was sensitive to gentamicin but became resistant to it. The computed tomography of the brain showed diffuse ventricular dilatation with no abnormal shadow in the cerebral hemisphere and posterior fossa. So we decided to administer rifampin 300mg P.O. daily and amikacin 120mg I.M. daily. Faver became normalized after 14 days of treatment. Neurologic examination was normal. The culture of CSF at that time revealed no growth of P. areugicnosa. He was discharged after 40 days of treatment. As mentioned above, no problem due to amilacin alone or amikacin with refampin. Until now, relationship between amikacin and refampin was not clear. Amikacin alone may be efficient to gentamicin-resistant P. aeruginosa infection. But because amikacin was given through intramuscular route in stead of intrathecal route and daily dosage of amikacin was 8mg/kg in stead of 15mg/kg, which was permissible dosage, the role of rifampin might not be neglected as trivial, even though there was no proof that rifampin was effective against Pseudomonase areuginosa espercially which was gentamicin-resistrant.

Recently the use of hydrochloric acid as a toilet disinfectant has become more common, and the risk of its ingestion is though to be increasing. We experienced a case of 67 year-old man who accidentally ingested hydrochloric acid and as a result developed a postprandial epigastric fullness end pain 3 weeks thereafter, The patient underwent an UGI series, fiberoptic gastroscope and abdominal ultrasonography and was found to have a gastric midbody stricture. A total gastreetomy and Roux-en- Y esophagojejunostomy was performed. We report this case with brief review of the literature.

PURPOSE: This study was to evaluate the effect of repeated ultrasonic scaling and surface polishing with intraoral polishing kits on the surface roughness of three different restorative materials. MATERIALS AND METHODS: A total of 15 identical discs were fabricated with three different materials. The ultrasonic scaling was conducted for 20 seconds on the test surfaces. Subsequently, a multi-step polishing with recommended intraoral polishing kit was performed for 30 seconds. The 3D profiler and scanning electron microscopy were used to investigate surface integrity before scaling (pristine), after scaling, and after surface polishing for each material. Non-parametric Friedman and Wilcoxon signed rank sum tests were employed to statistically evaluate surface roughness changes of the pristine, scaled, and polished specimens. The level of significance was set at 0.05. RESULTS: Surface roughness values before scaling (pristine), after scaling, and polishing of the metal alloys were 3.02±0.34 µm, 2.44±0.72 µm, and 3.49±0.72 µm, respectively. Surface roughness of lithium disilicate increased from 2.35±1.05 µm (pristine) to 28.54±9.64 µm (scaling), and further increased after polishing (56.66±9.12 µm, P<.05). The zirconia showed the most increase in roughness after scaling (from 1.65±0.42 µm to 101.37±18.75 µm), while its surface roughness decreased after polishing (29.57±18.86 µm, P<.05). CONCLUSION: Ultrasonic scaling significantly changed the surface integrities of lithium disilicate and zirconia. Surface polishing with multi-step intraoral kit after repeated scaling was only effective for the zirconia, while it was not for lithium disilicate.

PURPOSE: We compared prophylactic effects and complications of intravesical instillation of the Connaught and Tice strains bacillus Calmette-Guerin (BCG) in patients with stage pT1 bladder cancer. MATERIALS AND METHODS: A total of 98 patients with stage pT1 bladder cancer were treated with transurethral resection (TUR) between January 1992 and April 1998. Of the 98 patients, 51 received the Connaught strain BCG (81mg), 27 the Tice strain BCG (12.7mg) and 20 patients underwent TUR alone. The patients were followed-up for 18-78 months (mean 42.5months). The recurrence and progression rates, mean months to tumor recurrence, recurrence free survival rate, using Kaplan-Meier curve, and complications, were compared between the two BCG strain groups. RESULTS: The overall recurrence rate was 27.5% in the Connaught strain BCG group, 29.6% in Tice strain BCG group and 65% in TUR alone group. The mean months to tumor recurrence, and the recurrence free survival rate, showed that both BCG strain drugs were superior to TUR alone. Although the prophylactic efficacy of the Connaught strain BCG was a little higher than that of the Tice strain BCG, there were no significant differences in the recurrence rates and recurrence free survival rates between the two drugs. The incidences of complications were 94.1 and 85.2% in the Connaught strain BCG and Tice strain BCG groups, respectively. CONCLUSIONS: Both the Connaught and Tice BCG strains were superior to TUR alone in the prophylaxis of the recurrence in stage pT1 bladder cancer. There was no significant difference in the complication rates between the two groups. Therefore, both the Connaught and Tice BCG strains may be regarded as alternative treatments.
