Automatic hematology analyzers provide the leukocyte differential count and the useful flags of the various hematological parameters. We compared LH 750 (Beckman Coulter Co., Miami, FL, USA) with manual method on differential leukocyte counts and evaluated the usefulness of the suspect flags, provided by this instrument. The comparison of leukocyte differential counts between two methods showed good correlation coefficient (r), which were 0.95 (neutrophil), 0.92 (lymphocyte), 0.82 (monocyte) and 0.95 (eosinophil). The frequency of the total flags displayed on LH 750 were 15.5%, which included immature granulocyte/left shift 63.5%, nucleated RBC 14.6%, platelet clumps 13.1%, variant lymphocyte 50% and blast 16.6%. This instrument showed higher positive predictive value in the flags such as platelet clumps 68.8%, immature granulocyte/left shift 61.5%, nucleated RBC 27.3%, variant lymphocyte 50% and blast 16.7%. In this study, the leukocyte differential counts of LH 750 showed good correlation with manual method and the suspect flags also showed a good performance for applying the criteria of re-examination in the clinical laboratory.

On the basis of the 2009 business plan, 20,394 Korean native cattle and beef cattle were carried examination of bovine tuberculosis by using ELISA technique from March to December. As a result, 66 cattle tested positive for tuberculosis and showed 0.32% positive ratio. Intradermal tuberculin test about 66 cases of ELISA positive cattle was carried out, and all of 66 cattle were confirmed as negative. However, when 7 PPD-positive cattle derived from slaughterhouse were tested by 20k ELISA kit and MS ELISA kit, 3 (2 suspect) cattle and 5 cattle showed positive results, respectively. As compared to the results of PPD test, the concordance rates were 43% (71% included suspect) with 20k ELISA kit and 71% with MS ELISA kit.

Fibrofolliculoma is a benign tumor characterized by a smooth, dome-shaped papule of size 2-4 mm. Most fibrofolliculomas occur as multiple lesions, and very rarely, they are solitary. Herein, we report a case of solitary fibrofolliculoma found in the alar rim, without the typical characteristics of a fibrofolliculoma. A 42-year-old man visited the hospital with a protruding lesion that had occurred 1 year previously. A mass of size 5×7 mm was observed on the left alar rim. The tumor was dome-shaped and palpable. The patient did not have any similar lesions elsewhere. No family member was known to have such a lesion. An incisional biopsy was performed before surgery, and pathological examination revealed hyperkeratosis and dyskeratosis; however, an accurate diagnosis was not made. Complete resection was planned for the mass on the alar rim. The resected mass was subjected to permanent biopsy, and the pathological examination results led to the diagnosis of fibrofolliculoma. Therefore, when diagnosing a dome-shaped mass in the alar rim, despite the suspicion of a very rare disease, it is necessary to suspect fibrofolliculoma and consider the process from diagnostic examination to treatment.

Purpose: Most paraquat poisonings are easily diagnosed by history taking on physical examination, however, some are failed to be diagnosed initially if the poisoning was veiled. The purpose of this study was to explore the clinical characteristics of veiled paraquat poisoning. Methods: We retrospectively reviewed the medical records of patients whose discharge diagnosis was paraquat poisoning in one university teaching hospital between 1 Jan, 2001 and 31 Dec, 2010. Veiled paraquat poisoning was determined when there was a positive urine paraquat kit in patients who did not mention paraquat poisoning in an initial physical examination or had unknown cause of pulmonary fibrosis, acute renal failure, or multi-organ failure. Results: Of the 117 patients with paraquat poisoning during the study period, 6 patients (5.1%) had veiled paraquat poisoning. The clinical characteristics were 1) proteinuria - 6 (100%), 2) increased creatinine - 4 (66.7%), 3) green skin stains - 2 (33.3%), 4) mucosal ulcer - 3 (50%). Blood chemistry results were variable. Conclusion: We should suspect veiled paraquat poisoning for patients who have proteinuria, increased creatinine, green skin stain, mucosal ulcer and vomiting, or if they have rapidly progressing acute renal failure or multi-organ failure with unknown cause, even if patients didn't mention about paraquat poisoning upon the initial physical examination. In cases with the above clinical conditions, a thorough repeated physical examination including history taking and use of urine paraquat kits should be performed.

Right to counsel means a defendant has a right to have the assistance of counsel (i.e., lawyers), and if the defendant cannot afford a lawyer, requires that the government appoint one or pay the defendant's legal expenses. The right to counsel is generally regarded as a constituent of the right to a fair trial. Historically, however, not all countries have always recognized the right to counsel. The right is often included in criminal law and constitutional law etc. First, any person who is arrested or detained shall have the right to prompt assistance of counsel. When a criminal defendant is unable to secure counsel by his own efforts, the State shall assign counsel for the defendant as prescribed by act in article 12(4) of the constitutional law. Second, the defense counsel or a person who desires to be a defense counsel may have an interview with the defendant or the suspect who is placed under physical restraint, deliver or receive any documents or things and have any doctor examine and treat the defendant or the suspect in article 34 of the criminal law. Nonetheless, problems about guarantee of the rights to counsel to the national security violators like spy terrorist and etc will be important for Koreans to consider. That is because national security violators's cases are qualitatively different from general criminal offense's cases and historically, lawyer obstruct a investigation in the process of examination of a suspect for national security violators. Therefore, this study suggest a way that a restriction the rights to counsel with an attorney in cases of the national security violators. To this end, in this paper, I touch on restriction of right to counsel during interrogation in the England and Germany etc in comparison to that of Korea and review Korea's Supreme Court decision and Constitution Court decision to understand the prospective and trends for Korean investigation procedure improvement.

Toothache is one of the most common discomforts experienced by patients in dental clinic. If clinical and radiographic examinations do not reveal any pathologic findings, we can suspect nonodontogenic toothache. Nonodontogenic toothache can be caused by a variety of causes such as muscle disorders, sinus and nasal mucosal problems, neuropathic pain, neurovascular pain, psychogenic problems, and cardiogenic disease. A thorough history and clinical examination should be performed to confirm the cause of the pain, and more accurate diagnosis can be established through local anesthetic injection. If the nonodontogenic toothache is misdiagnosed, unnecessary dental treatment such as root canal treatment, periodontal treatment, and extraction can be performed, and the patient's pain is not alleviated through such treatment. Therefore, the cause of toothache must be diagnosed correctly before dental treatment is performed, and clinicians should be fully aware of the diseases that may cause these symptoms.

Pleomorphic adenoma is a benign tumor that can occur in the salivary glands, most commonly in the parotid gland. While it primarily occurs in the major salivary glands, it can sometimes be found in the minor salivary glands. Within the minor salivary glands, it most often originates in the hard palate and soft palate, and less frequently in the upper lips. Due to its location in the minor salivary glands, most pleomorphic adenoma involve and protrude on the mucosa. A 61-year-old man presented with 1.5 cm exophytic mass on the skin of his upper lip. This mass was exophytic on the skin and did not involve or protrude into the inner lip mucosa. The mass was entirely excised, and a subsequent permanent biopsy diagnosed it as a pleomorphic adenoma. In such situations, it can be challenging to suspect pleomorphic adenoma during a physical examination, leading to potential diagnostic confusion. It might also be mistaken for an inclusion cyst or another type of mass, making it tempting to treat without verifying the pathological results.

Mastocytosis is a rare disease which occurs in both children and adults, and it can manifest as a solitary or multiple skin lesions. Both can cause cutaneous or systemic symptoms. Because of the heterogeneity of clinical presentation of mastocytosis and its rare prevalence, it can be hard to suspect the mastocytosis at the first time. Most solitary mastocytomas are about 1-5 cm in diameter and have features of brownish-yellow, minimally elevated plaques with a smooth shiny surface. This article presents a case of solitary mastocytoma which occurred in neonate and that we treated through surgical excision. In histopathological examination, it consisted of c-kit-positive mast cells. Although pediatric cutaneous mastocytosis might regress spontaneously, clinicians should keep in mind that it could be associated with systemic mastocytosis which involves hematopoietic system.

This report details a case of 8-year-old girl showing failure of odontogenesis after chemo-radiation therapy for the rhabdomyosarcoma at the age of 4. The observed results were as follows : 1. Past history revealed that she had received for a total radiation dose of 4430cGy, 29 fractions in 6 weeks and chemotherapy with vincristine, actinomycin D and cytoxan, followed as maintenance phase for 2 years. 2. The patient was symptom -free and appointed for the treatment of multiple dental caries. 3. Oral examination showed hypoplastic enamel on whole erupted permanent teeth and showed retarded eruption. 4. Conventional radiograms showed failure of root development including abrupt cessation of root formation and root agenesis, and microdontia, missing teeth, irregular enamel, dislocation of the impacted teeth. Additional finding showed good healing bone pattern on the left mandibular ramus and angle area. 5. Cephalometric analysis revealed failure of bite raising due to incomplete eruption of all the first molars and made it possible to suspect entrapped mandibular growth and then Class II tendency growth. 6. There was correlation between the time of chemo-radiation therapy and the damage of the teeth.
