Orbital floor defect caused by invasive aspergillosis: a case report and literature review

Fungal sinusitis is relatively rare, but it has become more common in recent years. When fungal sinusitis invades the orbit, it can cause proptosis, chemosis, ophthalmoplegia, retroorbital pain, and vision impairment. We present a case of an extensive orbital floor defect due to invasive fungal sinusitis. A 62-year-old man with hypertension and a history of lung adenocarcinoma, presented with right-side facial pain and swelling. On admission, the serum glucose level was 347 mg/dL, and hemoglobin A1c was 11.4%. A computed tomography scan and a Waters’ view X-ray showed right maxillary sinusitis with an orbital floor defect. On hospital day 3, functional endoscopic sinus surgery was performed by the otorhinolaryngology team, and an aspergilloma in necrotic inflammatory exudate obtained during exploration. On hospital day 7, orbital floor reconstruction with a Medpor Titan surgical implant was done. In principle, the management of invasive sino- orbital fungal infection often begins with surgical debridement and local irrigation with an antifungal agent. Exceptionally, in this case, debridement and immediate orbital floor reconstruction were performed to prevent enophthalmos caused by the extensive orbital floor defect. The patient underwent orbital floor reconstruction and received intravenous and oral voriconazole. Despite orbital invasion, there were no ophthalmic symptoms or sequelae.

Intramuscular epidermal cyst in the masticator space: a case report

An epidermal cyst, also known as an epidermoid cyst or epidermal inclusion cyst, is the most prevalent type of cutaneous cyst. This noncancerous lesion can appear anywhere on the body, typically presenting as an asymptomatic dermal nodule with a visible central punctum. In the case presented herein, an epidermal cyst with uncommon features was misdiagnosed as a lymphatic malformation based on preoperative magnetic resonance imaging (MRI). A 61-year-old man came to us with a swollen left cheek that had been present for 11 months. The preoperative MRI revealed a 3 × 3.8 × 4.6 cm lobulated cystic lesion with thin rim enhancement in the left masticator space. The initial differential diagnosis pointed toward a lymphatic malformation. We proceeded with surgical excision of the lesion via an intraoral approach, and the specimen was sent to the pathology department. The pathological diagnosis revealed a ruptured epidermal cyst, indicating that the initial diagnosis of a lymphatic malformation based on preoperative MRI was incorrect. Epidermal cysts located under the muscle with no visible central punctum are uncommon, but should be considered if a patient presents with facial swelling.

Sensory change and recovery of infraorbital area after zygomaticomaxillary and orbital floor fractures

Background@#To compare the sensory change and recovery of infraorbital area associated with zygomaticomaxillary and orbital floor fractures and their recoveries and investigate the factors that affect them. @*Methods@#We retrospectively reviewed 652 patients diagnosed with zygomaticomaxillary (n= 430) or orbital floor (n= 222) fractures in a single center between January 2016 and January 2021. Patient data, including age, sex, medical history, injury mechanism, Knight and North classification (in zygomaticomaxillary fracture cases), injury indication for surgery (in orbital floor cases), combined injury, sensory change, and recovery period, were reviewed. The chi-square test was used for statistical analysis. @*Results@#Orbital floor fractures occurred more frequently in younger patients than zygomaticomaxillary fractures (p< 0.001). High-energy injuries were more likely to be associated with zygomaticomaxillary fractures (p< 0.001), whereas low-energy injuries were more likely to be associated with orbital floor fractures (p< 0.001). The sensory changes associated with orbital floor and zygomaticomaxillary fractures were not significantly different (p= 0.773). Sensory recovery was more rapid and better after orbital floor than after zygomaticomaxillary fractures; however, the difference was not significantly different. Additionally, the low-energy group showed a higher incidence of sensory changes than the high-energy group, but the difference was not statistically significant (p= 0.512). Permanent sensory changes were more frequent in the high-energy group, the difference was statistically significant (p= 0.043). @*Conclusion@#The study found no significant difference in the incidence of sensory changes associated with orbital floor and zygomaticomaxillary fractures. In case of orbital floor fractures and high-energy injuries, the risk of permanent sensory impairment should be considered.

The Bodily Panic Symptoms and Predisposing Stressors in Korean Patients with Panic Disorder / 신경정신의학

OBJECTIVES@#The purpose of this study was to investigate the distinctive features of bodily panic symptoms and the predisposing conditions in Korean patients with panic disorder.@*METHODS@#This was a retrospective chart review study and the data were collected from twelve university-affiliated hospitals in Korea. The patients selected met the diagnostic criteria for panic disorder, were older than 20 years of age, and had initially visited a psychiatry department. The assessments included the chief complaints related to bodily panic symptoms, recent stressors, recent history of alcohol and sleep problems, and time to visit an outpatient clinic.@*RESULTS@#A total of 814 participants were included in the study. The most commonly experienced symptoms were cardiovascular and respiratory symptoms, which were observed in 63.9% and 55.4% of participants, respectively. Just before the onset of a panic attack, 25.6% of participants experienced sleep-related problems. Episodic binge drinking was also frequently observed (13.2%) and was more prevalent in men than in women (22.6% vs. 4.9%, p<0.001). About 75% of participants experienced stressful life events just before panic onset. Work-related issues were more prevalent in men than in women (22.0% vs. 13.4%, p=0.001). Family-related issues (4.8% vs. 14.1%, p<0.001) and conflict with a spouse or partner (4.0% vs.11.7%, p<0.001) were more prominent in women than in men.@*CONCLUSION@#Our results suggest that cardiovascular symptoms are the most common bodily panic symptoms in Korean patients. Our results suggest that a substantial portion of the Korean patients experienced stressful life events, sleep problems, and/or episodic binge drinking just before the onset of panic disorder.

Inhibitory Effect of Rotundarpene on Parkinsonian Neurotoxin 1-Methyl-4-Phenylpyridinium-Induced Apoptotic Cell Death

BACKGROUND: The extract and hemiterpene glycosides of Ilex Rotunda Thunb exert antioxidant and anti-inflammatory effects. The effect of rotundarpene on apoptosis in neuronal cells caused by the 1-methyl-4-phenylpyridinium (MPP⁺) has not been reported previously. METHODS: Using differentiated PC12 cells and human neuroblastoma SH-SY5Y cells, we investigated the effect of rotundarpene on MPP⁺-caused apoptosis in relation to the cell death process. RESULTS: MPP⁺-induced cell death was identified using the MTT and neutral red uptake tests. Apoptosis was induced by eliciting decreases in the cytosolic levels of Bid and Bcl-2 proteins, increases in the cytosolic levels of Bax and p53, disruption of the mitochondrial transmembrane potential, and the release of cytochrome c and the activation of caspase-8, -9, and -3 in differentiated PC12 cells and SH-SY5Y cells. Treatment with rotundarpene reduced the MPP⁺-induced changes in the levels of apoptosis-regulated proteins, formation of reactive oxygen species, depletion and oxidation of glutathione, and cell death in both PC12 and SH-SY5Y cells. CONCLUSIONS: Rotundarpene may reduce MPP⁺-induced apoptosis in neuronal cells by suppressing the activation of the mitochondria-mediated pathway and the caspase-8 and Bid pathways. Rotundarpene appears to act by inhibiting the production of reactive oxygen species and by the depletion and oxidation of glutathione.

Balloon valvuloplasty for severe subaortic stenosis in a Pomeranian dog

A nine-month-old Pomeranian dog with exercise intolerance and syncope was presented. The dog was depressed with grade 4 systolic murmur on cardiac auscultation. Based on cardiac examination, the dog was diagnosed with severe subaortic stenosis with involvement of the anterior mitral valve. β-blocker administration was initiated and clinical signs were improved, but not fully resolved. Balloon valvuloplasty was performed and the dog survived for nearly one year without clinical sign and the cardiac troponin I level was normalized. This case describes successful management of severe subaortic stenosis in a small breed dog through balloon valvuloplasty.

Communicating Tubular Esophageal Duplication Combined with Bronchoesophageal Fistula

Esophageal duplication (ED) is rarely diagnosed in adults and is usually asymptomatic. Especially, ED that is connected to the esophagus through a tubular communication and combined with bronchoesophageal fistula (BEF) is extremely rare and has never been reported in the English literature. This condition is very difficult to diagnose. Although some combinations of several modalities, such as upper gastrointestinal endoscopy, esophagography, computed tomography, magnetic resonance imaging, and endoscopic ultrasonography, can be used for the diagnosis, the results might be inconclusive. Here, we report on a patient with communicating tubular ED that was incidentally diagnosed on the basis of endoscopy and esophagography during the postoperational evaluation of BEF.

A Recurrent Ischemic Stroke Stabilization after Using Non-Vitamin K Antagonist Oral Anticoagulant (NOAC)

Current stroke guidelines recommend the administration of non-vitamin-K-antagonist oral anticoagulant (NOAC) for the prevention of cardioembolic stroke induced by nonvalvular atrial fibrillation. We report a patient who suffered from recurrent posterior circulation strokes-occurring eight times in 4 months-even under adequate antiplatelet medication. Changing the medication from antiplatelet agents to NOAC stopped the stroke recurrence. We suggest that NOAC has a role in the prevention of recurrent stroke of undetermined etiology in the posterior circulation.

Association Analysis between (AAT)n Repeats in the Cannabinoid Receptor 1 Gene and Schizophrenia in a Korean Population

OBJECTIVES: Previous studies suggest that the cannabinoid receptor 1 (CNR1) gene could be an important candidate gene for schizophrenia. According to linkage studies, this gene is located on chromosome 6q14-q15, which is known to harbor the schizophrenia susceptibility locus (locus 5, SCZ5, OMIM 803175). The pharmacological agent delta-9-tetrahydrocannabinol (Delta-9-THC) seems to elicit the symptoms of schizophrenia. The association between CNR1 polymorphisms and schizophrenia is actively being investigated, and some studies have linked the AAT-trinucleotide repeats in CNR1 to the onset of schizophrenia. In this study, we have investigated the association between the AAT-trinucleotide repeats in CNR1 and schizophrenia by studying schizophrenia patients and healthy individuals from Korea. METHODS: DNA was extracted from the blood samples of 394 control subjects and 337 patients diagnosed with schizophrenia (as per the Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria). After polymerase chain reaction amplification, a logistic regression analysis, with age and gender as the covariates, was performed to study the variations in the AAT-repeat polymorphisms between the two groups. RESULTS: In total, 8 types of trinucleotide repeats were identified, each containing 7, 8, 10, 11, 12, 13, 14, and 15 repeats, respectively. (AAT)13 allele was most frequently observed, with a frequency of 33.6% and 31.6% in the patient and control groups, respectively. The frequency of the other repeat alleles in the patient group (in the decreasing order) was as follows : (AAT)13 33.6%, (AAT)14 21.6%, (AAT)12 18.5%, and (AAT)7 11.1%. The frequency of the repeat alleles in the control group (in the decreasing order) was as follows : (AAT)13 31.6%, (AAT)14 24.5%, (AAT)12 17.2%, and (AAT)7 11.6%. However, there were no significant differences in the AAT-repeat polymorphisms of the CNR1 gene between the patient group and the control group. CONCLUSIONS: Although our study revealed no significant association of the AAT-repeat polymorphism of the CNR1 gene with schizophrenia, it will serve as a good reference for future studies designed to examine the cannabinoid hypothesis of schizophrenia.

Depression and self-concept in girls with perception of pubertal onset

PURPOSE: Early pubertal timing in girls is associated with psychological and behavioral problems. This study aimed to evaluate the psychological features of girls who perceived breast development beginning by analyzing their depression levels and self-concept. METHODS: From March 2007 to December 2012, 93 girls were enrolled and assigned to a pre-8 (younger than 8 years, n=43) or post-8 (8 years and older, n=50) group according to the age at onset of perceived breast development, and their height, body weight, body mass index, bone age (BA), Tanner stage, and luteinizing hormone and follicle-stimulating hormone levels were examined. We investigated their psychological state with the Korean Children's Depression Inventory (CDI) and Piers-Harris Children's Self-Concept Scale (PHCSC) to evaluate depression levels and self-concept, respectively. RESULTS: The pre-8 group had a significantly greater height standard deviation score, (0.5+/-1.01 vs. 0.11+/-0.86, P = 0.048) and more advanced BA (2.07+/-1.02 years vs. 1.40+/-0.98 years, P = 0.004) compared to the post-8 group. There were no statistically significant intergroup differences for the CDI and PHCSC scores; however, the pre-8 group scored higher than the post-8 group in the physical appearance and attributes domain of the PHCSC (9.93+/-2.57 vs. 8.52+/-3.03, P = 0.017). CONCLUSION: The timing of perceived breast development among girls who thought puberty to begin did not affect depression levels and self-concept. There was no correlation between Tanner stage and depression levels and self-concept despite the perception of pubertal onset. The pre-8 group had a more positive view of their physical appearance than the post-8 group.

Subclinical Vitamin D Insufficiency in Korean School-aged Children / 대한소아소화기영양학회지

PURPOSE: Recently, vitamin D insufficiency has increased and has been correlated to growth and puberty in children. This study was conducted to find the prevalence of subclinical vitamin D insufficiency and its influence on school-aged children in Korea. METHODS: The subjects of this study were 397 children aged 7 to 15 years who had been tested for 25-OH vitamin D3 among the outpatients of the Department of Pediatrics in Eulji General Hospital from March 2007 to February 2011. Data for age, sex, comorbidities, serum 25-OH vitamin D3, height, weight, body mass index (BMI), and sunlight exposure time were collected before and after 3 months of vitamin D administration, retrospectively. RESULTS: Vitamin D insufficiency was present in 343 (86%) of the subjects. In the vitamin D insufficient group, chronological age was 8.96+/-1.72 years, mean height (z-score [z]) was 0.51+/-1.26, mean BMI (z) was 0.81+/-2.20, and bone age was 10.26+/-1.75 years. In the vitamin D sufficient group, chronological age was 9.61+/-1.77 years, mean height (z) was-0.66+/-0.98, mean BMI (z) was-0.01+/-1.16, and bone age was 9.44+/-2.12 years. A paired t-test showed that three months after vitamin D administration, the mean 25-OH vitamin D3 level in the insufficient group increased to 24.38 +/-10.03 ng/mL and mean BMI (z) decreased to 0.67+/-1.06. CONCLUSION: In Korean school-aged children, vitamin D insufficiency were relatively higher and may be closely related with higher BMI. Insufficient rise of the level of vitamin D after supplementation suggest the new supplementation guidelines, especially for Korean children.

A General Hospital-Based Model for Early Detection of Depression in the Geriatric Patients with Chronic Medical Diseases

The geriatric patients with chronic physical diseases are frequently associated with the continuous clusters of depression including nonpathological sadness, subsyndromal depression, minor depressive disorder, and major depressive disorder. Because of the complex and reciprocal relationships among depression, elderly, and chronic physical diseases, screening approaches with specific nosological methods should be needed in the realm of early detection of depression. Cognitive decline is frequently manifested in geriatric depression with medical or neurological diseases. Also, somatic symptoms of depression or emotional symptoms of physical diseases can play a role as a hampering factor in the early detection of depression. Furthermore, after-care has been regarded as an essential factor of depression screening in the geriatric patients with chronic physical diseases. We reviewed the most popular examples of integrated medicine for depression in primary care. Thus, we propose a general hospital-based model for early detection of depression which includes favorable response loop between screening and therapeutic intervention. Our model can be a basis for evidence-based detection and after-care for depression in the geriatric patients with chronic medical diseases.

Colonization Rate of Methicillin-resistant Staphylococcus aureus in Neonates: A Single Center Experience / 소아감염

PURPOSE: The aim of this study is to investigate the colonization rate of Methicillin-resistant Staphylococcus aureus (MRSA) in neonates by different clinical characteristics, to presume the origin of MRSA acquisition, and to identify the risk factors associated with MRSA colonization. METHODS: We retrospectively reviewed the medical records of 1,733 neonates admitted to Seoul Eulji hospital Neonatal Intensive Care Unit between January 2008 and December 2011. Nasal, inguinal and rectal swab specimens were obtained upon admission and each week until discharge. We classified the route of MRSA acquisition as; hospital associated (HA-MRSA) and community associated (CA-MRSA) according to the case definition. RESULTS: Among 1,733 neonates, 415 (23.9%) were colonized with MRSA. Gestational age, birth weight, delivery type, maternal antibiotics usage before delivery, birth place and care place before admission were influencing factors in colonization of MRSA. The colonization rate was significantly high in neonates without maternal prophylactic antibiotics use before delivery than in the other group (relative risk 2.77, 95% CI 1.88-4.07; P<0.01), and outborns showed higher MRSA colonization rate compared to inborns (relative risk 2.28, 95% CI 1.17-4.42; P=0.015). CONCLUSION: We identified the neonatal MRSA colonization rate to be 23.9%. We estimated HA-MRSA colonization rate to be 10% (51/511) and CA-MRSA colonization rate to be 36% (309/858). We ascertained that risk factors in MRSA colonization in neonates were prophylactic use of antibiotics in mothers and the birth place.
