ABSTRACT

Hyperplastic anterior choroidal artery (AchA) is an extremely rare congenital vascular variant that can be mistaken for other cerebral arteries. This case report presents a 38-year-old man who presented with a severe sudden-onset headache and was diagnosed with a ruptured aneurysm originating from a hyperplastic AchA. The aneurysm was successfully treated with coil embolization, but recurrence was detected after eight months, leading to additional surgical intervention. The discussion highlights the classification of hyperplastic AchA and emphasizes the importance of recognizing this anatomical variant to avoid complications during treatment. This case report underscores the need for awareness and understanding of hyperplastic AchA in the management of cerebral aneurysms.

ABSTRACT

Objective@#: Deciphering the anatomy of posterior communicating artery (PCoA) aneurysms in relation to surrounding structures is essential to determine adjuvant surgical procedures. However, it is difficult to predict surgical structures through preoperative imaging studies. We aimed to present anatomical structures using preoperative high-resolution three-dimensional proton densityweighted turbo spin-echo magnetic resonance (PDMR) imaging with simple classification. @*Methods@#: From January 2020 to April 2022, 30 patients underwent PDMR before microsurgical clipping for unruptured PCoA aneurysms in a single tertiary institute. We retrospectively reviewed the radiographic images and operative data of these patients. The structural relationship described by PDMR and intraoperative findings were compared. Subsequently, we classified aneurysms into two groups and analyzed the rate of adjuvant surgical procedures and contact with the surrounding structures. @*Results@#: Correlations between preoperative PDMR predictions and actual intraoperative findings for PCoA aneurysm contact to the oculomotor nerve, temporal uncus, and anterior petroclinoid fold (APCF) reported a diagnostic accuracy of 0.90, 0.87, and 0.90, respectively. In 12 patients (40.0%), an aneurysm dome was located on the plane of the oculomotor triangle and was classified as the infratentorial type. Compared to the supratentorial type PCoA aneurysm, adjuvant procedures were required more frequently (66.7% vs. 22.2%, p=0.024) for infratentorial type PCoA aneurysm clipping. @*Conclusion@#: Preoperative PCoA aneurysm categorization using PDMR can be helpful for predicting surgical complexity and planning of microsurgical clipping.

ABSTRACT

Acute generalized exanthematous pustulosis (AGEP) is characterized by acute nonfollicular sterile pustules on a background of edematous erythema. Hydroxychloroquine (HCQ), an antimalarial drug, widely used to treat rheumatic and dermatologic diseases. HCQ has been reported to be an uncommon cause of AGEP. We report a 60-year-old woman with rheumatoid arthritis requiring the use of HCQ presented fever and erythematous eruption on the trunk with sterile pustules. Leukocytosis and elevated erythrocyte sedimention rate noted on laboratory examination. On the histopathological examination of the skin biopsy specimen showed neutrophilic infiltration and scattered eosinohpils. The lesions were resolved with removal of HCQ. The clinical course was consistent with the diagnosis of AGEP associated with HCQ. We reported a case of typical AGEP associated with HCQ in a patient with Rheumatoid arthritis. The patient presented resolution from cutaneous lesions with withdrawal of culprit drug, without the need of systemic steroid.

ABSTRACT

BACKGROUND: Cotinine, a nicotine metabolite detected in urine, has been recommended as the best quantitative marker of smoking and environmental tobacco smoke (ETS) exposure. The aim of this study was to analyze the relationship between indoor ETS and urinary cotinine level of the passive smokers. METHODS: We selected 42 nonsmokers who lived in Seoul and were not exposed to passive smoking at least 5 days before test. Urinary cotinine levels were measured by Smokescreen Colorimeter (Surescreen Diagnostics LTD, U.K.). We measured urinary cotinine levels twice (before and after smoking exposure). RESULTS: The mean urinary cotinine level was 0.33microgram/mL before smoking exposure, and 0.46microgram/mL after smoking exposure. There was statistically significant difference (P-value=0.003). There was no significant difference between exposure time and increase of urinary cotinine level(P=0.138, r=-0.233). There was also no significant difference between measuring time taking after exposure and increase of urinary cotinine level (P=0.671, r=0.067). CONCLUSION: One experience of indoor exposure to ETS caused significant elevation of urinary cotinine level.

ABSTRACT

Placental abnormality is the important predisposing cause of intrauterine growth retardation. Massive subchorionic hematoma is defined as a large size of maternal blood clot that separates the chorionic plate from the villous chorion and can result in serious obstetrical complications. We report a case of massive subchorionic hematoma diagnosed prenatally, and propose an additional peculiar finding detectable on both the ultrasound and magnetic resonance images: a large hematoma in the subchorionic region at 17 weeks gestation. At 18 weeks 2 days gestation, the fetus was miscarried. The clinical and pathological findings were compatible with massive subchorionic hematoma. Recurrent massive subchorionic hematoma without thrombophilic finding was observed at the next pregnancy in 17 weeks 5 days by ultrasound. The patient was managed conservatively and had successful outcome at term. So we report the case with the brief review of literatures.

ABSTRACT

OBJECTIVE: The study shows that the DFS is a questionnaire that almost effortlessly can be completed within 60-90 seconds during any moment of labor and delivery. The aim of the present study was to test the validity and reliability of the DFS, to identify its factor structure in Korea. METHODS: Review of the medical records from the department of obstetrics and gynecology from January to April 2005, a confirmed 51 patients with the diagnosis of singleton pregnancy without medical or obstetrical complications, being in 37-42 weeks. 22 primiparous and 29 multiparous women answered the Delivery Fear Scale (DFS) once during active labor, and the STAI (State-Trait Anxiety Inventory) after delivery. Reliability test to calculate Chronbach alpha and validity test to measure correlation between DFS and STAI was done. Then factor analysis was applied with the method of principal component analysis and varimax rotation. RESULTS: Korean version of DFS proved to be a reliable and valid scale statistically: Cronbach's alpha was 0.7182 in study. CONCLUSION: Women's psychological experiences during the actual process of labor and delivery are essential part of obstetrical care. Nevertheless, studies examining psychological variables concerning childbirth, are mostly performed before or after labor. The DFS measures fear during labor and delivery in an effortless and fast away. The development of the Korean version of DFS which is reliable and valid, and consists of three sub-factors may facilitate future research in the field.

ABSTRACT

Otocephaly is a rare malformations comprising hypoplasia or absence of the mandible (agnathia), ventromedial displacement and often fusion of external ears (synotia or otocephaly), and hypoplasia of the oral cavity (microstomia) and tongue (hypoglassia). This developmental complex represents a malformation of the first and second branchial arches and occurs sometimes with holoprosencephaly. We present the ultrasound detection of otocephaly and holoprosencephaly with cyclopia in a fetus of 27 gestational weeks 6 days. The use of three-dimensional (3-D) ultrasound made additional diagnostic ultrasound tomograms possible, and the volume reconstructions improved the imaging and the understanding of the condition.

ABSTRACT

Cervical spine injury occurs in 3% of blunt trauma patients, and 10% of patients with cervical spine injuries have an associated head injury. The early recognition of cervical spine injury and treatment of the secondary injury are important in the management of trauma patients. At the time of diagnosis of cervical spine injury, 5~30% of patients have been reported to have experienced missed or delayed diagnosis. Of these, 10.5~29% were associated with permanent and critical neurologic injury, for example, death, quadriplesia, ect. The writers experienced two cases of missed traumatic cervical spine injury.
