Neonatal diabetes mellitus (NDM) is defined as hyperglycemia that presents clinical symptoms within the first month of life and requires insulin therapy to maintain euglycemia. The diabetic condition may be transient, permanent, or transient with recurrence later in life. NDM is a rare clinical disorder. Three cases of NDM have been reported in Korea so far. We experienced two cases of NDM in twin brothers who were born with small for gestational ages. Their HLA typings were DR9 and DR14, and insulin autoantibody, islet cell antibody, GAD-reactive autoantibody, and insulin receptor antibody were not found. The genetic analysis with polymorphic DNA markers for chromosome 6 indicated paternal uniparental isodisomy.

BACKGROUND: Many shoulder diseases are related to glenohumeral joint synovitis and effusion. The purpose of the present study is to detect effusion within the biceps long head tendon sheath as the sign of glenohumeral joint synovitis using ultrasonography, and to evaluate the clinical meaning of effusion within the biceps long head tendon sheath. METHODS: A consecutive series of 569 patients who underwent ultrasonography for shoulder pain were reviewed retrospectively and ultimately, 303 patients were included. The authors evaluated the incidence and amount of the effusion within the biceps long head tendon sheath on the ultrasonographic short axis view. Furthermore, the authors evaluated the correlation between the amount of effusion within the biceps long head tendon sheath and the range of motion and the functional score. RESULTS: The effusion within the biceps long head tendon sheath was detected in 58.42% of the patients studied: 69.23% in adhesive capsulitis, 56.69% in rotator cuff tear, 41.03% in calcific tendinitis, and 33.33% in biceps tendinitis. The average amount of the effusion within the biceps long head tendon sheath was 1.7 +/- 1.6 mm, and it was measured to be the largest in adhesive capsulitis. The amount of effusion within biceps long head tendon sheath showed a moderate to high degree of correlation with the range of motion, and a low degree of correlation with the functional score and visual analogue scale for pain in each type of shoulder disease. CONCLUSIONS: The effusion within the biceps long head tendon sheath is closely related to the range of motion and clinical scores in patients with painful shoulders. Ultrasonographic detection of the effusion within the biceps long head tendon sheath might be a simple and easy method to evaluate shoulder function.

The numb chin syndrome (NCS) is characterized by chin or lower lip numbness restricted to the distribution of the mental nerve (the distal trigeminal nerve). The authors report a patient whose initial symptom of tumor recurrence was unilateral numbness of the chin. A 65-year-old male was admitted because of paresthesia around the left chin and left lower lip. Neurologic examination revealed hypesthesia on the left side of chin, lower lip and buccal mucous mem-brane. Bone scan (Tc-99m MDP) showed focal hot uptakes on the left mandible and left first rib. Brain CT with bone window setting showed a focal osteolytic lesion in the bone marrow of the left mandibular canal without destruction of bone cortex. Both coronal T1 weighted image and axial T2 weighted image showed focal low signal intensities on the left ramus. The pathophysiologic mechanism could be understood by identification of the pathologic focus.

Severe cough may contribute to serous coplications such as pneumothorax, pneumomediastinum, rib fracture, subconjunctival hemorrhage, subdural hemorrhage and cough syncope. However abdominal wall hematoma is a rare complication. Because it usually presents with abdmoianal pain, abdominal wall hematoma needs to be differentiated from the acute surgical abdomen. A 78-year-old woman was admitted with right lower quadrant abdominal pain and a palpable mass for several days. She experienced abdominal pain after violent coughing associated with an upper respiratory tract in fection. Abdominal computed tomography revealed an approximately 7×4 cm sized, ill-defined, soft tissue density lesion in the right lower posterolateral abdominal wall. An abdominal wall hematoma was diagnosed. After admission, she had persistent right lower abdominal pain and an increasing mass. The mass was surgically removed and she was discharged without complications. In summary, when a patient complains of abdmonial pain after severe coughing, an abdominal wall hematomas as a differential diagnosis must be considered.

BACKGROUND: The recent studies shows that LV relaxation abnormalities are the important factors of heart failure in elders. To determine the association between LV diastolic functions and heart failure, we assessed LV diastolic functions in elderly patients with pulmonary congestion and in asymptomatic elders by using pulsed doppler echocardiography. METHODS: In order to assess LV diastolic function, we performed pulsed doppler echocardiography to elderly patients with pulmonary congestion and asymptomatic elders from Mar.2001 to Sep.2001. The following parameters were used as indices of LV diastolic function; Mitral E wave(E), Mitral A wave(A), Deceleration time(DT), Isovolumic relaxation time(IVRT), Systolic pulmonary venous flow(PVs), Diastolic pulmonary venous flow(PVd). RESULTS: In elderly patients groups, there was significant increase in deceleration time compared with asymptomatic elders(255.83+/-54.41 vs 210.80+/-48.53, p<0.05). There was significant increase in isovolumic relaxation time in elderly patient group compared with asymptomatic elders(123.06+/-25.07 vs 98.78+/-15.12, p<0.01). Although there was no significant difference, decreased E/A ratio and increased PVs/PVd were noted in both groups. CONCLUSIONS: The results shows that the impairments of LV diastolic function were noted in both groups. Especially DT and JVRT were significant increase in elderly patient group with pulmonary congestion. Therefore these parameters, such as DT, IVRT, can be helpful as predictive indices of diastolic heart failure in elders.

The temporalis muscle is usually described as a single layer originating at the temporal line, converging to a tendon, and inserting onto a narrow site of the coronoid process. However, recent studies have shown that the temporalis muscle can be divided into two or three separate segments and the distal attachment continues inferiorly beyond the coronoid process. Therefore, the aims of this study were to analyze the morphology of the temporalis muscle focusing on the tendinous attachment onto the coronoid process and to provide educational values. The temporalis muscle was carefully dissected in 26 cadavers and classified based on the muscle fascicle direction. Each divided part was sketched and measured based on bony landmarks to elucidate its tendinous insertion site onto the coronoid process, and the results obtained were reviewed through the literature. The temporalis muscle ends at two distinct terminal tendons with wider insertion sites than usually presented in textbooks and atlases and separates into two parts that combine to act as a single structural unit. The superficial part is a large fan-shaped muscle commonly recognized as the temporalis muscle. This converges infero-medially to form the superficial tendon and the lateral boundary of the retromolar triangle. Meanwhile, the deep part is a narrow vertically oriented rectangular muscle that converges postero-laterally to form the deep tendon and the medial boundary of the retromolar triangle. These results indicate that understanding the temporalis muscle’s insertion site onto the coronoid process will be useful clinically with educational values during surgical procedures.

OBJECTIVE: To examine the association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and hyperhomocysteinemia in women with unexplained recurrent miscarriages (RM) and to investigate the association between MTHFR genotype variants and alloimmune activation, proportion of peripheral blood natural killer (pbNK) cells. METHODS: A total of 39 patients with a history of two or more unexplained miscarriages were recruited to this study. The controls were women who had a live birth without a history of RM (n=50). The proportion of pbNK cells was measured by flow cytometry. Plasma homocysteine levels and the incidence of the MTHFR variant of the RM and control groups were compared. The proportion of pbNK cells was compared to the MTHFR variants in the RM group. RESULTS: No differences were found between the two groups' mean plasma homocysteine levels (7.6+/-1.5 micromol/L vs. 7.1+/-2.1 micromol/L) or incidence of the MTHFR genotype variant (CC, 35% vs. 33%; CT, 40% vs. 53%; and TT, 25% vs. 14%). In the RM group, individuals with the TT variant (7.7+/-1.1 micromol/L) had higher homocysteine levels than those with the CC and CT variants (7.4+/-1.9 micromol/L and 7.4+/-1.2 micromol/L) and those with the CT variant (19.2+/-8.1%) had a higher proportion of CD3-/CD56+ pbNK cells than those with the CC and TT variants (17.7+/-6.6% and 17.9+/-7. 0%), but the results of both comparisons were statistically insignificant. CONCLUSION: These preliminary results show no difference in plasma homocysteine levels between the RM and control groups or among MTHFR genotype variants in the RM group, which may suggest that the plasma homocysteine level is difficult to use as a predictive marker of RM in the Korean population. A study of a larger number of patients is needed.

In this study the dosimetric evaluation for a biological sample irradiated by gamma rays from Cs-137 irradiator (Gamma Irradiator, Chiyoda Technol Co., Japan) was performed for radiobiological experiment. A spherical water with a diameter of 3 cm was assumed as a biological sample. The absorbed dose were determined by the air kerma based dosimetric calculation system. The theoretical and Monte Carlo calculations (MCNPX) were performed and compared to evaluate measured air kerma and determined absorbed dose respectively. As a result of comparison with theoretical calculation, the measured air kerma was in good agreement within 3.1% at the distance of 100 and 200 cm from the source. In comparison with Monte Carlo results the determined absorbed dose along the central axis was in good agreement within 1.9% and 3.7% at 100 cm and 200 cm respectively. Although the preliminary results were obtained in this study these results were used as a basis of dosimetric evaluation for radiobiological experiment. Extended study will be performed to evaluate the dose in various conditions of biological samples.
