Prosthetic restoration of the patient with inaccurate pronunciation after prosthesis fabrication through systematic diagnosis and treatment procedure: A case report / 대한치과보철학회지

Recently, there are cases where anterior esthetic prostheses are fabricated for better esthetics, but biologic, mechanical factors could be overlooked, too focusing on esthetic factor. This leads to changes in neutral zone, dentition, position of tongue and lips, occlusion and anterior guidance causing inaccurate pronunciation. Therefore, consideration of systematic diagnosis and treatment procedure are required. In this case, prosthesis was refabricated through a systematic diagnosis and treatment procedure using four factor (acoustic analysis, esthetic analysis, occlusion, neutral zone) for the patient who complained of inaccurate pronunciation and esthetics of the fixed prosthesis fabricated 10 years ago. Thus, by promoting functional, esthetic recovery, this case report demonstrates satisfying results to both the patient and dentist.

Esthetic improvements through systematic diagnosis and treatment procedures in patients with unesthetic maxillary anterior teeth proportion after orthodontic treatment: Case report / 대한치과보철학회지

The treatment of areas demanding esthetic requirements, such as maxillary anterior teeth, should take into account the achievement of a healthy, harmonious to the surrounding tissue, and an attractive smile line. In this case report, smile line, soft tissue and hard tissue morphology, and the anatomy and proportion of the tooth, must be considered. In patients with unesthetic maxillary anterior ratio due to inadequate gingival contour and diastema caused by peg lateralis, it would be challenging to achieve an esthetic restoration by orthodontic treatment alone. In such case, after orthodontic treatment, dento-gingivo-facial compositional diagnosis and analysis, followed by gingivectomy and prosthodontic restoration is needed to improve the interdental mesial/distal, width/length ratio to achieve a satisfactory esthetic result. In addition, when improving the tooth proportion of peg lateralis by prosthodontic treatment, Porcelain laminate veneer (PLV), which results in less tooth structure loss, reproduction of similar shade to that of the proximal tooth and high transparency, is recommended. This case report demonstrates esthetic improvements by prosthodontic restoration through systematic diagnosis and treatment procedure in patients with unesthetic maxillary anterior proportion after orthodontic treatment due to peg lateralis by means of two female patients aged twenty years old.

A Case of Needleless Jet Injector Induced Bilateral Chorioretinal Injury

PURPOSE: To report a case of bilateral chorioretinal injury by needleless jet injector misuse. CASE SUMMARY: In a dermatology department, the patient was diagnosed as having total alopecia and was scheduled to be injected on her eyelash by needleless jet injector for treatment but inexpert doctor injected on the eyelid, not eyelash, by mistake. She then suddenly complained of blurred vision and a floater just after that procedure and was referred to the ophthalmology department. Bilateral vitreous hemorrhage and preretinal hemorrhage were seen during indirect ophthalmoscopic examination and bilateral prophylactic argon laser photocoagulation was done around the suspicious tear site. Then bilateral vitreous hemorrhage and preretinal hemorrhage were absorbed and we found a partial retinal rupture lesion and choroidal rupture lesion in the right eye and a retinal injury lesion in the lefteye. Therefore we observed the lesions of both eyes continuously without further treatment. Her clinical symptoms improved. CONCLUSIONS: Needleless jet injector has many advantages, especially less pain and injury than a normal needle injector and is usually used in clinic as preoperative local anesthesia and steroid injection in many medical fields. In this case, the needleless injector was accidentally misused inducing both direct and indirect choroidal rupture and retinal injury. In general, while a needleless jet injector is used in ophthalmology department, we have to use it with the greatest care.

Proper Respiratory Rate Determination during Controlled Ventilation in Infants under General Anesthesia / 대한마취과학회지

BACKGROUND:We experienced unintentional hyperventilation during mechanical ventilation in infants under general anesthesia. It is very difficult to decide upon respiratory rate or tidal volume for adequate ventilation without respiratory gas monitoring. During pulmonary ventilation using a Mapleson D circuit, the utilization of high fresh gas flow dilutes the expired gas and causes an underestimation of end-tidal CO2. We undertook to find a proper respiratory rate (RR) with a fixed tidal volume during controlled ventilation in infant general anesthesia. METHODS: We studied 50 infants weighing below 10 kg during general anesthesia. An uncuffed endotracheal tube was selected 3.5 or 4.0 mm (inner diameter). After intubation with midazolam, thiopental sodium and vecuronium, controlled ventilation was applied: total fresh gas flow 3 L/minute, peak inspiratory pressure 15-20 cmH2O, and RR 19 or 20/minute. Arterial blood gas analysis was done 20 minutes later. We calculated the RR for a PaCO2 of 36 mmHg according to the equation: RR (applied) = estimated RR x estimated PaCO2/ideal PaCO2. In addition, linear regression was performed to analyze the relation between age and RR. RESULTS: The estimated regression equation for RR using Pearson's correlation coefficient was as follows: RR = 22.835 - 0.415 x age (months). CONCLUSIONS: The equation (RR = 22.835 - 0.415 x age [months]) could be used as an index for safe ventilatory management without severe hyper- or hypo-carbia in infants during general anesthesia.

Tc-99m ciprofloxacin imaging in diagnosis of chronic bacterial prostatitis / 亚洲男科学杂志(英文版)

<p><b>AIM</b>To investigate the value of Tc-99m ciprofloxacin imaging in the differential diagnosis of chronic bacterial prostatitis.</p><p><b>METHODS</b>The study included 4 normal subjects as the negative controls, 2 patients with acute prostatitis or cystourethritis as the positive controls and 59 patients diagnosed as chronic bacterial prostatitis or chronic pelvic pain syndrome by traditional laboratory tests. In every subject, the single photon emission computerized tomography images were obtained 3 h after intravenous injection of Tc-99m Ciprofloxacin. The results of the imaging were compared with those of laboratory tests.</p><p><b>RESULTS</b>On the images, negative uptake was observed in all normal subjects, while strong hot uptake, in the whole prostate of acute prostatitis patients and in the whole urethra of acute cystourethritis patients. In 13 (68%) of 19 patients categorized as chronic bacterial prostatitis by standard laboratory tests, hot uptake with less intensity than that of acute prostatitis was observed in the prostate area around the prostatic urethra. Negative uptake in the prostate was observed in 6 of 19 patients (32%) categorized as chronic bacterial prostatitis. Interestingly, hot uptake in the prostate was exhibited in 28 (70%) of the 40 patients categorized as chronic pelvic pain syndrome.</p><p><b>CONCLUSION</b>Tc-99m ciprofloxacin imaging is helpful in the differential diagnosis of prostatitis syndrome.</p>

The Change of Visual Evoked Potential in Patients with Myopia in Correction of Refraction

OBJECTIVE: Multiple factors including age, sex, habituation, refraction, cooperation and technical variables are associated with P100 latency of Visual evoked potential (VEP). So we tried to evaluate the P100 latency of visual evoked potential according to refraction. METHOD: We studied 28 patients (12 males, 16 females) with myopia. Subjects were divided into 3 groups (mild, moderate, severe myopia) according to refraction and we evaluated the results of VEP studies. RESULTS: Mean values of refraction and latency (P100) of naked eyes were -4.27 D, 103.95 msec. and those of corrected eyes (in glasses) were -0.25 D, 100.59 msec. Respectively, in mild, moderate and severe myopia, the each P100 latency of naked eyes were 101.27 msec, 102.59 msec, 107.99 msec and those of corrected eyes were 98.33 msec, 100.58 msec, 102.19 msec respectively (p<0.05). There was significant negative correlation between refraction and P100 latency in myopia. CONCLUSION: Our results suggested that there were significant changes in VEP (P100 latency) according to refraction. In performing the VEP study, we should consider the refraction and visual acuity.

A Case of Metastatic Lung Cancer Presenting with Isolated Hypoglossal Nerve Palsy

The peripheral hypoglossal nerve palsy is caused by carotid aneurysm, vascular entrapment, local infection, trauma, neck radiation, and tumors in the neck, retropharyngeal spaces, and basilar area of skull. A basilar skull lesion may rarely involve the hypoglossal nerve alone. We report a 58-year-old man with isolated hypoglossal nerve palsy due to metastasis of lung cancer at the skull base.

Primary Renal Lymphoma in a Child / 대한비뇨기과학회지

Primary renal lymphoma is a controversial entity and extremely rare disease, possibly due to the fact that the kidney is one of the extranodal organs usually not containing lymphoid tissue. It is unclear if this conditions can be diagnosed preoperatively with imaging studies. In most cases the diagnosis is made after removal or biopsy of a kidney for suspected primary renal tumor or at autopsy. Treatment usually consists of surgery and chemotherapy with or without radiation therapy and the prognosis is poor. We report a case of primary renal lymphoma presenting with fever in a 13-month- old boy who was treated with surgical intervention and combination chemotherapy.
