Functional dyspepsia is a condition with chronic indigestion symptoms such as epigastric pain or discomfort, early satiety, and bloating without an alternative organic disease. The symptoms are similar to those of functional dyspepsia, but abnormal retention of food in the stomach should be identified in gastroparesis. In this case, botulinum toxin injection was performed for treatment in a patient who complained of symptoms such as nausea, early satiety, abdominal distension, and poor appetite without no abnormal findings in gastric emptying scan. Through this case, a possibility was found that antral and pyloric dysfunction may cause symptoms of functional dyspepsia, without gastric emptying abnormalities.
Objective: We investigated the diagnostic accuracy of high-resolution magnetic resonance angiography (HR-MRA) with volume rendering (VR) post-processing techniques for the detection of cerebral aneurysms compared with conventional MRA (C-MRA) using digital subtraction angiography (DSA) as the gold standard.Methods: HR-MRA was performed for 51 possible aneurysms of 38 patients on C-MRA. For each possible aneurysm, readers recorded their level of confidence on a 5-point scale. All patients underwent DSA, which was used as the standard of reference. Receiver-operating characteristic (ROC) analysis and the area under the ROC curves (AUC) were used to determine the effectiveness of C-MRA and HR-MRA in detecting cerebral aneurysm with and without VR algorithm. The increased discriminative value was examined by calculation of Net Reclassification Index (NRI) and Integrated Discrimination Improvement (IDI) index.Results: DSA revealed 37 aneurysms in 26 patients. In aneurysm-based analysis, HR-MRA showed higher diagnostic accuracy than C-MRA, and increased diagnostic accuracy on adding VR (C-MRA vs. HR-MRA, P< 0.01; C-MRA with VR vs. HR-MRA with VR, P< 0.01, respectively). The differences in AUC, IDI (19.38%, Z= 3.18, P< 0.01) and NRI (46.3%, Z= 6.32, P< 0.01), on adding VR to the HR-MRA, were also statistically significant. The application of HR-MRA with VR increased the detection rate of aneurysms less than 3 mm.Conclusion: The application of HR-MRA with VR algorithm improves diagnostic performance for the detection of intracranial aneurysms, especially when the aneurysm is less than 3 mm. Clinically, HR-MRA with VR algorithm could facilitate the accurate differentiation of aneurysms from infundibula and prevent unnecessary, invasive procedure before aneurysmal rupture.
Objective: Despite Korea’s low birth rate, pediatric emergency medical centers (PEMCs) are grappling with overcrowding. This study evaluates the use of PEMCs in Korea amid a declining birth rate and increased overcrowding.Methods: Data from 176 emergency medical centers (EMCs, 2018–2021) was analyzed using the National Emergency Department Information System, focusing on demographics, Korean Triage and Acuity Scale (KTAS) scores, and pediatric patient outcomes. The most common complaints and diagnoses were identified by the EMC level. This study also examined the characteristics of patients visiting PEMCs.Results: There was a 48% drop in pediatric visits to EMCs during the coronavirus disease 2019 (COVID-19) pandemic. The majority of patients were boys aged 1–4, primarily visiting in the evenings and weekends. The breakdown of cases included 66% disease-related and 34% injury-related. Notably, 8.5% of these visits were via ambulance, 36% were high-acuity according to KTAS, 88% resulted in discharge, and 11% in hospitalization. The median stay was 85 minutes, with 83% utilizing local emergency services. Fever, abdominal pain, and vomiting were the most common complaints, comprising 40% of all visits.Conclusion: Despite a decrease in birth rates, PEMC usage in Korea saw an initial rise followed by a significant decrease during the COVID-19 pandemic. Children aged 1–4 were the most frequent users. The majority of cases were medical rather than trauma-related, and resulted in patient discharge. Strategic redirection of non-urgent cases may help alleviate overcrowding in emergency departments.
Objective: Osteomyelitis in patients with diabetic foot has been diagnosed clinically, radiologically, and histologically. However, the accuracy of these diagnostic modalities is not well established. In this study, we histologically reviewed patients who underwent surgical procedures for diabetic foot osteomyelitis and correlated these histological features with radiological findings.Methods: Eighty patients who were clinically diagnosed with diabetic foot osteomyelitis, who underwent surgical treatment between November 2017 and February 2022, were enrolled. Hematoxylin and eosin-stained slides and radiological findings were reviewed.Results: Eighty patients were radiologically examined by magnetic resonance imaging (MRI) (49 cases) and/or 99mTc-hexamethyl-propylene amine oxime-labeled white blood cells single-photon emission computed tomography (SPECT)/computed tomography (CT) (65 cases). MRI findings were suggestive of osteomyelitis in 35 cases (71.4%) and soft tissue inflammation in 46 cases (93.8%). In SPECE/CT, 60 cases (92.3%) and 64 cases (98.4%) showed signs of osteomyelitis and soft tissue inflammation, respectively. Histologically, both bone and soft tissue lesions were found in 32 cases (40%), only bone tissue lesions in seven cases (8.8%), and only soft tissue lesions in 40 cases (50%). The sensitivity and specificity of MRI for osteomyelitis were 83.3% (10/12) and 28.6% (4/14), and that of SPECT/CT was 100.0% (12/12) and 12.5% (2/16), respectively. Moreover, those of by MRI findings for soft tissue inflammation were 90.6% (29/32) and 0% (0/12), while that of SPECT/CT was 97.4% (38/39) and 0% (0/18), respectively.Conclusion: For accurate histological diagnosis of diabetic foot osteomyelitis, sufficient specimens should be obtained. White blood cell SPECT/CT seems to be a more sensitive modality than MRI for the detection of osteomyelitis.
Jamu sticks are used in some Southeast Asian cultures especially Indonesia for vaginal health and tightening. However, there is no scientific evidence supporting the safety or effectiveness of Jamu sticks for vaginal tightening or health. Chemical reactions caused by these foreign substances can lead chemical vaginitis, increasing the risk of secondary infection through the disrupted vaginal wall. I report a case of a patient successfully treated for vaginal stenosis due to chemical vaginitis caused by Jamu sticks experienced in our hospital and advise caution against indiscriminate folk remedies.
Hypovolemic shock and septic shock present similar symptoms, such as increased heart rate and decreased blood pressure. However, the two conditions have different causes, mechanisms, and treatment approaches. Early differentiation between the two conditions can have a positive impact on patient prognosis. In this case, the patient underwent a right ovarian cystectomy due to a teratoma torsion during a previous pregnancy, followed by treatment for a postoperative infection. While recovering, the patient underwent an emergency cesarean section due to sudden severe abdominal pain. After the surgery, unstable vital signs were suggestive of hypovolemia due to massive bleeding from the cesarean section. Therefore, fluid infusion and blood transfusion were initiated. The vital signs did not improve. So, the patient was reassessed. Body temperature and the previously elevated C-reactive protein levels were remeasured. The results of the reassessment indicated a septic condition due to previous infection. The patient was prescribed additional vasopressors and antibiotics for the following week. Subsequently, the patient’s vital signs stabilized, and the treatment was discontinued.
Muco-submucosal elongated polyp is a non-neoplastic growth composed of normal mucosa and submucosal tissue. It was first reported by Matake and his colleagues and has been found mainly in the colon. The term colonic muco-submucosal elongated polyp was proposed for colonic lesions. However, only a few cases have been reported in the duodenum and jejunum of the small intestine. These lesions are called enteric muco-submucosal elongated polyp, and intussusception is very rare. In this case report, I experienced a case of enteric muco-submucosal elongated polyp that occurred in the jejunum of the small intestine and caused intussusception.
Perforation of a Meckel’s diverticulum with a foreign body is a rare complication. Whether in children or adults, fish bones have been reported to cause perforation in a Meckel’s diverticulum, but few cases have been reported in which swallowing relatively large bones such as chicken bones results in perforation. We report a case of perforation of a Meckel’s diverticulum caused by swallowing a chicken bone.
Baclofen, a gamma-aminobutyric acid-B receptor agonist, is commonly used for central-origin muscle spasticity and spasm and neuropathic pain. Baclofen toxicity has been reported to cause a range of symptoms including drowsiness, confusion, respiratory depression, seizures, and even coma, particularly with dosage significantly exceeding therapeutic levels. Given that the baclofen is predominantly eliminated through the kidneys, patients with renal failure are at substantial risk for neurotoxic effects. We report a case of baclofen-induced encephalopathy in a patient with end-stage renal disease, characterized by an altered mental state with myoclonus following the consumption of a low dose of baclofen.
Differentiating between nocturnal seizures and sleep-related behaviors is challenging; a detailed history and careful examination are imperative. There have been some case reports of patients who were comorbid with nocturnal seizures and obstructive sleep apnea (OSA). Here, we report a case of an overweight 12-year-old boy diagnosed with sleep-related epilepsy and comorbid OSA. We were able to make these two diagnoses by performing polysomnography with full extended electroencephalography on our patient, who complained of recurrent nocturnal choking episodes during sleep. What differentiates our case is that after further evaluation, the cause of our patient’s OSA was ultimately determined to be laryngeal lymphoid hyperplasia.
Myosin heavy chain 9 (MYH9) related diseases are autosomal dominant diseases characterized by macrothrombocytopenia and inclusion bodies in leukocyte, which can be accompanied by extra-hematologic symptoms such as sensorineural hearing loss, renal dysfunction, and cataract. They are often diagnosed incidentally in adulthood or misdiagnosed as idiopathic thrombocytopenic purpura (ITP), leading to unnecessary treatment with intravenous high-dose gamma-globulin, steroids, or splenectomy. Here, we report the case of a brother and sister confirmed to have a MYH9 gene mutation during follow-up. An 8-year-old boy was confirmed to have thrombocytopenia at birth and treated with intravenous gamma-globulin under suspicion of ITP or sepsis. He was discharged after showing an increase in platelet count. Subsequently, during outpatient workup, he exhibited thrombocytopenia, large platelets, and neutrophilic inclusion bodies. His 10-year-old sister also presented with the same findings. In 2021, DNA analysis revealed that they share a mutation (c.4270G> A, p. Asp1424Asn), a pathogenic variant associated with MYH9-related disorder.
Objective: To compare the clinical and radiologic results between primary total hip replacement arthroplasty (THRA) in patients with avascular necrosis of femoral head (AVN) and secondary THRA in patients with fixation failure of femoral neck fracture.Methods: From March 2014 to February 2021, we retrospectively evaluated a total of 53 patients who underwent either THRA for AVN (33 cases) or THRA for fixation failure of femoral neck fracture (20 cases). Clinical performances and Hemodynamic scales were evaluated. Radiologic analyses were conducted to assess stem alignment, stem stability, the appearance of heterotrophic ossification, stress shielding, and any signs of osteolysis or loosening.Results: THRA for AVN showed a mean blood loss of 881 mL and a 2.1 g/dL preoperative–postoperative (preop–postop) hemoglobin (Hb) difference. Meanwhile, THRA for fixation failure of femoral neck fracture showed a mean blood loss of 1,072 mL and a 3.2 g/dL preop–postop Hb difference (P= 0.017 and P= 0.034, respectively). The mean operation time was 70 minutes in THRA for AVN and 91 minutes in THRA for fixation failure of femoral neck fracture (P= 0.035). Stem alignment was varus 1.50° in AVN and varus 3.50° in fixation failure of femoral neck fracture. There was one case of a varus femoral stem in AVN and six such cases in the fixation failure of femoral neck fractures. This was a statistically significant difference (P= 0.010 and P= 0.020, respectively).Conclusion: Secondary THRA in patients with fixation failure of femoral neck fracture showed longer operation time, larger bleeding, and more varus stem alignment than primary THRA in patients with AVN.
Skin burn injury from light cables is a rare complication of laparoscopic surgery. We report the case of a 57-year-old female who underwent laparoscopic-assisted right hemicolectomy under general anesthesia. During surgery, the anesthesiologist discovered that the tip of the light cable, with the light source powered on, penetrated the surgical drape and was positioned on the right forearm of the patient, where a bulla measuring 2.0× 2.5 cm in size and a second-degree burn were identified. All medical personnel participating in laparoscopic and arthroscopic procedures should always be aware that the light cable can cause burns to the patient. Additionally, after connecting the light cable to the scope, the light source should be activated. The light cable should not be placed around the patient or on the surgical drape while the light source is active. Immediately after completing the surgery, the power to the light source should be turned off, and the light cable should be placed in a safe place.
Nodular histiocytic/mesothelial hyperplasia (NHMH) is a very rare condition. It is generally thought to be associated with repeated mechanical or chemical stimulation. This study reported NHMH with papillary growth pattern in the ovary following high-intensity focused ultrasound (HIFU) treatment for uterine leiomyoma and adenomyosis. A 48-year-old female, who had a history of undergoing HIFU treatment 7 times for adenomyosis and leiomyoma of the uterus 6 months ago, was referred to the hospital. After the hysterectomy and right salpingo-oophorectomy, the patient was confirmedly diagnosed with nodular histiocytic and mesothelial hyperplasia with the papillary growth pattern of the right ovary. This benign reactive inflammatory lesion of the mesothelium mimicking malignancy must be kept in mind to avoid unnecessary treatment.
Lymphangioleiomyomatosis is a rare disease characterized by the proliferation of atypical smooth muscle cells. Recurrent pneumothorax is a frequent complication of lymphangioleiomyomatosis. We present the case of a 41-year-old woman who presented with recurrent pneumothorax. Video-assisted thoracic surgery was performed. We did not suspect the possibility of lymphangioleiomyomatosis because of the presence of very few cysts on chest computed tomography.
Patients with type II Alexander disease have white matter dysplasia, which may cause various symptoms due to nerve conduction impairment. When providing anesthesia to a patient with Alexander disease, careful and patient-specific individualized risk evaluation must be preceded by planning the method of anesthesia and anesthetic drugs. This is the first case report of a patient with type II Alexander disease who underwent general anesthesia. We performed general anesthesia on a 45-year-old male with type II Alexander disease for laparoscopic cholecystectomy, using remimazolam, remifentanil, and rocuronium. Despite the use of reversal agents including flumazenil, naloxone, and sugammadex, the patient manifested a delay in emergence but successfully recovered from anesthesia without postoperative complications. In consideration of the possibility that leukodystrophy may have altered responses to anesthetics, the action of an anesthetic agent may be prolonged or delayed in patients with type II Alexander disease. We recommend using drugs with a short duration of action and which can be reversed immediately by a reversal agent.
Imatinib mesylate is an effective, small-molecule, selective tyrosine kinase inhibitor, which inhibits BCR-ABL in patients with chronic myeloid leukemia, c-kit in patients with gastrointestinal tumor (GIST), and platelet-derived growth factors in hypereosinophilic syndrome. Above all, bone marrow necrosis is a rare complication of imatinib usage. If newly developed increased opacity bone lesions are seen in patients with metastatic GIST, it is usual to consider those lesions as bone metastasis. Also, it is true that making a differential diagnosis between bone marrow change (bone marrow necrosis) and disease progression (bone metastasis) is both clinically and radiologically difficult. Because it may alter treatment options according to early distinguish bone metastasis and imatinib related-bone necrosis, a bone biopsy is recommended. Here, we report a case that a biopsy confirmed bone marrow necrosis due to imatinib, even though investigations such as magnetic resonance imaging, and whole-body bone scan indicated more favor to the metastatic lesion.
Reconstruction using osteocutaneous fibular free flap after radical resection of oral cancer with mandibular invasion and segmental mandibulectomy is the gold standard of treatment. Recent technological advances have made virtual surgical planning and threedimensional printing incorporating computer-aided design and computer-aided modeling possible, thereby shortening the ischemic time of free flap and enabling more sophisticated reconstruction. We report a successful case of osteocutaneous fibular free flap using this technique.
Spontaneous intracranial hypotension (SIH) is a condition caused by spontaneous cerebrospinal fluid (CSF) leakage, resulting in orthostatic headache as the main symptom, but other symptoms such as memory loss, nausea, and tinnitus may also be present. Various imaging techniques are used to diagnose SIH, with magnetic resonance imaging myelography being an important tool for detecting the leakage site of CSF. Conservative treatments including hydration, bed rest, and intravenous caffeine have been tried with limited success. Epidural blood patch (EBP) is the most commonly performed treatment for SIH after the failure of conservative management. There are different opinions about the EBP procedure (e.g., blind EBP vs. targeted EBP). This report describes the treatment of SIH with targeted EBP according to imaging diagnosis after the failure of initial blind lumbar EBP.
Tatton-Brown-Rahman syndrome (TBRS) is a relatively new congenital anomaly syndrome manifesting overgrowth and a broad spectrum of intellectual disability. It is caused by pathogenic variants in the DNA methyltransferase 3 alpha (DNMT3A) gene, mainly de novo inheritance. Overgrowth, mild-to-severe intellectual disability, and other clinical features of TBRS may affect the quality of life of patients and their family members. Thus, early diagnosis by genetic testing and management of these symptoms is critical. We report a case of a 17-year-old male patient with hemihypertrophy who suffered back pain since school age, diagnosed with TBRS-identified DNMT3A gene mutation.
