PURPOSE: To report the surgical results of unilateral pediatric cataracts from uncertain causes in relatively older children and to identify factors related to better visual outcomes. METHODS: We retrospectively evaluated the medical records of 39 patients who underwent surgery between the ages of 3 and 10 years for unilateral pediatric cataracts of no known cause. All patients underwent primary intraocular lens implantation and postoperative amblyopia treatment. A postoperative final visual acuity better than 20 / 30 was considered to be a good visual outcome. RESULTS: The mean age of patients was 6.0 ± 1.8 years at the time of surgery. The mean preoperative visual acuity was 1.07 ± 0.71 logarithm of the minimum angle of resolution (range, 0.15 to 3.00), while the mean final postoperative visual acuity was 0.47 ± 0.54 logarithm of the minimum angle of resolution (range, 0.00 to 2.00). Of 39 patients, 18 (46.2%) achieved a good visual outcome. Only the preoperative visual acuity maintained a significant association with a good visual outcome according to our multivariate analysis (p = 0.040). A preoperative visual acuity of 20 / 100 or better was found to increase the chance of achieving a good visual outcome by 13.79-fold (95% confidence interval, 1.13 to 167.58). CONCLUSIONS: The visual outcome of unilateral pediatric cataract surgery for cataracts with no specific cause identified in patients after three years of age could be satisfactory, especially with a preoperative visual acuity of 20 / 100 or better.

Anterior knee pain (AKP) syndrome is one of the most common conditions that prompt active young individuals to seek evaluation at sports injury clinics. Compared to the general population, patients with AKP appear to be at a higher risk of developing patellofemoral osteoarthritis. AKP can be detrimental to the affected patient’s quality of life and, in the larger context, it could markedly burden the economy with high healthcare costs. This opinion aims to present a comprehensive evaluation of AKP to improve its management in clinical practice.Current Concepts: AKP has a multifactorial etiology. It can be attributed not only to structures within and around the knee but also to external factors, such as limb malalignment, weakness of specific hip muscle groups, and core and ligamentous laxity. Hence, AKP warrants a detailed evaluation of patient’s medical history and a thorough clinical examination complemented by relevant radiological investigations to identify its origin in the knee and the underlying cause. Conservative management yields favorable outcomes in the majority of patients with AKP, whereas surgical management becomes necessary only when well-characterized structural abnormalities of the knee or limb correlate with the clinical presentation of AKP or when conservative measures fail to provide substantial and sustained symptoms relief.Discussion and Conclusion: The treatment strategy for AKP should be individualized based on the patient’s profile and the specific cause identified. Therefore, the management of AKP requires a focused evaluation of the patient’s medical history, clinical examination, and radiological investigations to identify the condition’s origin and underlying cause.

OBJECTIVES: Entrapment of the suprascapular nerve is frequently overlooked in the differential diagnosis of shoulder pain. METHODS: Suprascapular entrapment neuropathy is a well-defined clinical entity and EMG and NCV is used to confirm a diagnosis. But the diagnosis is typically not considered until patients develop severe weakness secondary to atrophy of the spinous musculature that the nerve supplies. RESULTS: A narrow suprascapular notch has rarely been reported as a work-related factor of this entrapment neuropathy. Diagnosis of suprascapular entrapment neuropathy is based on the patients' clinical course, neurologic, radiologic, and electrophysiologic findings. One of the most helpful evaluations was the anteriorposterior projection with the X-ray tube angled 15-30 degree caudally. The suprascapular entrapment neuropathy is relatively uncommon entity of shoulder discomfort (pain, weakness, and atrophy). CONCLUSIONS: If the worker who used his shoulder joint repetitiously having the shoulder pain and muscle weakness, we must rule out the suprascapular entrapment neuropathy. And it is needed to evaluate the motions which cause suprascapular entrapment neuropathy as the ergonomic factor.

PURPOSE: Thyroid cancer is the most common malignancy affecting the endocrine glands. The incidence of his malady has conspicuously increased during the recent years. Thyroid diseases affect women approximately 3 times more often than men, and this incidence decreases after menopause. This gender difference has suggested that the female sex steroids stimulate the growth of the thyroid, the same as for the breast. In the present study, we investigated the expressions of estrogen receptor (ER) and progesterone receptor (PR) in thyroid lesions. METHODS: The tissues from 193 human thyroid glands (136 thyroid cancers and 57 adenomatous hyperplasias) were used for the present immunohistochemical assessment of the ER and PR expressions. RESULTS: The incidences of the estrogen and progesterone receptor positive cases were 19.7 and 41.5%, respectively. The incidence of the progesterone receptor positive cases was higher for females (46.5%) than for males (19.4%) however, the expression of estrogen receptor was not different significantly between the females and males. Higher expressions of estrogen and progesterone receptors were detected in the thyroid cancers than in the adenomatous hyperplasias. The PR expression seemed to correlate with the tumor size: a higher PR expression was found in the T3 cancers than in the T2 cancers. CONCLUSION: Our findings provide new insight that the ER and PR expressions may be related to the pathogenesis and progression of thyroid cancer.

BACKGROUND: Research of clinical contents and proper development of education program is essential in family medicine. Therefore, this study is carried out to obtain data for residency training, and to provide references to family physicians who give primary health care in rural community by analyzing prospectively the clinical contents of new patients in a local family practice clinic. METHODS: The authors visited family practice clinic in a rural area practiced by a family physician board certified in family medicine. There were 3,126 new patients from Jan. 1996 to Dec. 1996 evenly distributed by month and area, 1,000 patients were sampled randomly and the collected data were classified according to the ICPC(International Classification of Primary Care) coding system. RESULTS: Among the selected 1,000 patients, males were 432(43.2%) and females were 568(56.8%). Age distribution was highest In the fifties(50-59 years old) (20.7%). The total number of Reason For Encounter(RFE) was 1,417, the average RFE was 1.41 per patient and the kind of RFEs was 93, among which cough was the most frequent RFE by 233 cases(16.4% ). The 87 kinds of diagnoses were used and URl(Upper Respiratory Infection) accounted for the major portion by 287 cases(21.9%). The diagnostic examination per patient was 0.42. The most frequently used test was x-ray of an extremity by 68 cases(16.1% ). Referrals to other departments were made in 3.3% of visitors of which Internal Medicine was highest(39.4%). CONCLUSIONS: The clinical contents were classified more comprehensively by using ICPC with given code RFE, care process, and diagnosis. More study on ICPC is necessary for classification to help analyze clinical contents in primary care.

BACKGROUND: Occasionally, combinations of antibiotics are used for the treatment of scrub typhus. However, the effectiveness of such combined therapies has rarely been evaluated. To date, no experimental studies have been performed; only 1 clinical study has assessed the efficacy of combined doxycycline and rifampin therapy. To elucidate the efficacies of other antibiotic combinations, we performed an experiment to evaluate the in vitro efficacy of antibiotic combinations against Orientia tsutsugamushi. MATERIALS AND METHODS: O. tsutsugamushi strain Boryong was inoculated into the ECV304 cell line. The infected cells were cultured in antibiotic-containing media for 3-5 days and stained with FS15, a monoclonal antibody reacting against the linear epitope on the 56-kDa major outer membrane protein of O. tsutsugamushi. Thereafter, antimicrobial susceptibility was measured by flow cytometry and expressed as a growth index (total mass of Orientia). The growth indices of doxycycline (0.1 microg/mL), azithromycin (0.1 microg/mL), rifampin (0.0125 microg/mL), cefotaxime (2 and 20 microg/mL), and their various combinations (doxycycline+cefotaxime, doxycycline+rifampin, azithromycin+cefotaxime, and rifampin+cefotaxime) were measured. The above mentioned antibiotic concentrations, except for that of cefotaxime, represent the minimal inhibitory concentrations of each antibiotic. RESULTS: The growth indices of doxycycline (4.67% and 0.52%), rifampin (2.35% and 0.26%), and azithromycin (7.54%) were within the range of full suppression of O. tsutsugamushi; in contrast, cefotaxime (87.60%) was in effective. The growth indices of doxycycline+rifampin were 0.10% and 0.10%, which were similar to those obtained with doxycycline or rifampin alone. The growth indices of doxycycline+cefotaxime were 3.99% and 3.65% in low-dose cefotaxime (2 microg/mL), and 3.69% and 4.40% in high-dose cefotaxime (20 microg/mL). The growth indices of rifampin+cefotaxime (2.19% and 2.19% at 2 microg/mL; 1.84% and 2.04% at 20 microg/mL cefotaxime) were similar to those obtained with rifampin alone (2.35% and 0.26%). Azithromycin+cefotaxime (11.06-14.63%) showed higher growth indices than azithromycin alone; this suggests that this combination may be antagonistic. Conclusions: The anti-Orientia efficacies of doxycycline+rifampin, doxycycline+cefotaxime, and rifampin+cefotaxime were not antagonistic. The efficacy of the azithromycin+cefotaxime combination needs to be confirmed by more sensitive methods to exclude the possibility of antagonistic interactions between the antibiotics.

OBJECTIVE: The objective of this study was to test the hypothesis that hemoglobin concentration after return of spontaneous circulation (ROSC) is associated with neurologic outcome after cardiac arrest in patients treated with targeted temperature management. METHODS: We studied consecutive adult patients with out-of-hospital cardiac arrest treated with targeted temperature management between January 2009 and December 2015. We investigated the association between post ROSC hemoglobin concentrations and good neurologic outcome (defined as Cerebral Performance Category of 1 and 2) at hospital discharge using multivariate logistic regression analysis. RESULTS: A total of 246 subjects were ultimately included in this study. The mean age was 54 years (standard deviation, 17); 168 (68%) subjects were male. Eighty-seven (35%) subjects had a good neurologic outcome at hospital discharge. Hemoglobin concentrations were higher in the good outcome group than in the poor outcome group (14.4±2.0 vs. 12.8±2.5 g/dL, P < 0.001). Multivariate logistic regression analysis showed that hemoglobin concentrations were associated with good neurologic outcome at hospital discharge after adjusting for other confounding factors (adjusted odds ratio, 1.186; 95% confidence interval, 1.008 to 1.395). CONCLUSION: In post ROSC patients, hemoglobin concentrations after ROSC were associated with neurologic outcome at hospital discharge.
