PURPOSE: To examine the effects of atropine therapy on myopic progression in myopic children. METHODS: Fifty myopic patients, aged from 7 to 14 years and less than -5 diopters, visited our clinic for correction of refractive error from August 2001, and were followed up for at least 1 year. Of these 50 patients, the atropine therapy group was 23 and the control group was 27. Right eye cycloplegic refraction and axial length changes of the two groups were compared and analyzed. RESULTS: There was a mean increase of myopia of 0.25+/-0.43 D/yr in the atropine therapy group and of 0.83+/-0.37 D/yr in the control group (P=0.000). There was a mean increase of axial length of 0.12+/-0.19 mm/yr in the atropine therapy group and 0.39+/-0.21 mm/yr in the control group (P=0.000). In refraction and axial length changes according to age, there was no statistically significant difference within the group, aged from 7 to 9 years. However, there was a statistically significant difference within the group, aged from 10 to 14 years. In refraction and axial length changes according to myopic grade, there were a statistically significant differences between the groups. CONCLUSIONS: Atropine therapy is effective in slowing the myopic progression in myopic children with refractive error less than -5 diopters.

Background: s/Aims: The treatment landscape for hepatocellular carcinoma (HCC) has significantly evolved over the past decade. We aimed to analyze trends in treatment patterns for HCC using a nationwide claims database from the Korean Health Insurance Review and Assessment Service. Methods: This retrospective population-based cohort study analyzed 171,002 newly diagnosed HCC patients between 2008 and 2022. Etiologies and treatment modalities were categorized based on the ICD-10 codes and insurance data. Results: The annual incidence decreased from 11,814 in 2008 to 10,443 in 2022. However, patients aged ≥70 increased noticeably, with those aged ≥80 rising from 3.8% in 2008 to 13.1% in 2022. From 2008 to 2022, the predominant cause of hepatitis B virus decreased from 68.9% to 59.7%, whereas nonalcoholic fatty liver disease increased from 8.9% to 15.8%. The initial treatment trends shifted: surgical resection and systemic therapy increased from 12.2% to 21.3% and from 0.2% to 9.6%, whereas transarterial therapy decreased from 49.9% to 36.6%. Best supportive care decreased from 31.7% to 21.3%. In the subgroup analysis, laparoscopic resection rate increased from 10.6% to 60.6% among the surgical resections. Sorafenib initially accounted for 100%, lenvatinib peaked at 36.5% in 2021, and atezolizumab-bevacizumab became the most widely used (63.1%) by 2022 among the systemic therapies. Conclusions This study demonstrates the temporal changes in the treatment patterns of Korean HCC patients. Surgical resection, particularly laparoscopic liver resection, and systemic therapy has increased significantly. These changes may have been influenced by reimbursement policies and advances in clinical research.

PURPOSE: The purpose of our study was to review the perinatal clinical characteristics of extremely low birth weight(ELBW) infants and determine their risk factors of their deaths. METHODS: The medical records of 96 infants weighing less than 1,000g, who were born at Seoul National University Hospital and admitted to our neonatal intensive care unit(NICU) were analyzed retrospectively on the basis of clinical characteristics, obstetrical problems, postnatal complications and outcome. RESULTS: The annual birth rate of ELBW infants was 0.11% to 0.90% of total live births and the mean annual birth rate was 0.56% at Seoul National University Hospital. Preeclampsia was the most common obstetrical problem(34.4%), followed by incompetent internal os of cervix(IIOC) (13.5%), multiple pregnancy(13.5%) and in vitro fertilization(IVF)(13.5%). Respiratory distress syndrome(RDS) was the most common postnatal complication(78.1%), followed by sepsis(60.4%) and apnea(39.6%). Comparing the ELBW infants weighing less than 750g with those weighing more than 751g, sepsis was more frequent in the latter group(p<0.05), whereas high grade intraventricular hemorrhage(grade Ill) was more frequent in the former group(p<0.05). Otherwise there was no statistically significant difference concerning the frequency of perinatal complications between two groups. Comparing the ELBW infants born before the year 1991, when surfactant treatment started to be used routinely at our NICU, with those born after the year 1991, apnea and sepsis could be observed more frequent in the latter group(p<0.05). Otherwise there was no statistically significant difference in the frequency of perinatal complications between two groups, The survival rate of ELBW infants was 0.0% in 1986, 50.0% in 1991 and 40.0% in 1995. The risk factors of neonatal deaths of ELBW infants included birth weight, gestational period, mode of delivery, IIOC, RDS, apnea, pneumonia, pneumothorax, acute renal failure(ARF) and infections(except pneumonia), but analyzing these risk factors by multivariate logistic regression analysis, the resultant significant independent risk factors consisted only of birth weight, RDS and pneumonia(p<0.05). There was no statistically significant difference in survival rate between ELBW infants born before and after the year 1991, but there was a tendency toward increasing survival rates in the latter group. CONCLUSION: Recently, the survival rate of ELBW infants is improving steadily, but is still lower than that of western countries and postnatal morbidity remains high. Therefore, there is an urgent need to give more efforts to the neonatal intensive care of ELBW inFants in order to increase survival rates and reduce postnatal morbidity. But it is more important to reduce preterm birth by the treatment of preventable obstetrical risk factors.

Few cases of ichthyosis bullosa of Siemens(IBS) have been reported since 1939, as a distinct entity from bullous congenital ichthyosiform erythroderma(BCIE). IBS can be differentiated from BCIE by the absence of congenital erythroderma and a different distribution of involved skin area. It's characteristic features include blistering, superficial erosion or moulting of the outer skin. Histological features are tonofilaments aggregation confined to the granular and upper spinous layer of the epidermis. However, in BCIE these findings are present in the whole suprabasal compartment. The original reports of Siemens and cases from other authors showed an autosomal dominant inheritance. Our patient developed IBS sporadically without a familial background.

We herein report a case of occupational contact urticaria syndrome induced by cefotiam di-hydrochloride in a nurse. She had generalized pruritic wheals accompanied by palpitations and tachypnea during the preparation of cefotiam solution. A scratch patch test with cefotiam di-hydrochloride, a major component of cefotiam ingredient showed multiple erythema and wheals within 5 minutes, accompanied by palpitations and tachypnea. No delayed type reaction was observed. Based on her clinical history and scratch test result, we diagnosed her condition as contact urticaria syndrome caused by cefotiam.

BACKGROUND: Pregabalin is an anticonvulsant and analgesic agent that interacts selectively with the voltage-sensitive-Ca(2+)-channel alpha-2-delta subunit. The aim of this study was to evaluate whether the analgesic action of intrathecal (IT) pregabalin is associated with KATP channels in the rat formalin test. METHODS: IT PE-10 catheters were implanted in male Sprague-Dawley rats (250-300 g) under inhalation anesthesia using enflurane. Nociceptive behavior was defined as the number of hind paw flinches during 60 min after formalin injection. Ten min before formalin injection, IT drug treatments were divided into 3 groups: normal saline (NS) 20 microl (CON group); pregabalin 0.3, 1, 3 and 10 microg in NS 10 microl (PGB group); glibenclamide 100 microg in DMSO 5 microl with pregabalin 0.3, 1, 3 and 10 microg in NS 5 microl (GBC group). All the drugs were flushed with NS 10 microl. Immunohistochemistry for the KATP channel was done with a different set of rats divided into naive, NS and PGB groups. RESULTS: IT pregabalin dose-dependently decreased the flinching number only in phase 2 of formalin test. The log dose response curve of the GBC group shifted to the right with respect to that of the PGB group. Immunohistochemistry for the KATP channel expression on the spinal cord dorsal horn showed no difference among the groups 1 hr after the formalin test. CONCLUSIONS: The antinociceptive effect of pregabalin in the rat formalin test was associated with the activation of the KATP channel. However, pregabalin did not induce KATP channel expression in the spinal cord dorsal horn.
