Black adenoma is known to be a rare variant of adrenal cortical adenoma containing characteristic abundant lipofuscin pigments in the cytoplasm. Almost all of them are nonfunctioning and only occasionally they are associated with Cushing's syndrome or primary hyperaldosteronism. We present two cases of black cortical adenoma of the adrenal gland associated with Cushing's syndrome in a 24-year-old woman and a 64-year-old man. This report dealt with clinical and pathologic presentation including ultrastructural identification of lipofuscin pigment.

Sacrococcygeal chordoma is a rare malignant tumor which is believed to take its origin from remnants of the fetal notochord, and presents in the sacral hollow or occasionally posteriorly. The growth is leisurely and it is invasive rather than metastatic. In treatment, there is evidence that early diagnosis of sacrococcygeal chordoma followed by radical resection c palliative radiotherapy does provide the opportunity for cure. We have experienced two cases of sacrococcygeal chordoma, which were treated with one case of a complete surgical resection and the other case of only biopsy.

Objective:
Sudden traumatic physical injuries often cause psychological distress, which may be associated with chronic disability. Although considerable effort has been expended to identify genetic predictors of post-traumatic stress disorder (PTSD) after traumatic events, genetic predictors of psychological distress in response to severe physical injuries have been yet to be elucidated using whole exome sequencing (WES). Here, the genetic architecture of post-traumatic syndrome (PTS), which encompasses a broad range of psychiatric disorders after traumatic events including depression, anxiety disorder, acute stress disorder, and PTSD, was explored using WES in severely physically injured patients, focusing on secondary findings and potential PTS-related variants.
Methods:
In total, 141 severely physically injured patients were consecutively recruited, and PTS was evaluated within 1 month of the injury. Secondary findings were analyzed according to PTS status. To identify PTS-related variants, genome-wide association analyses and the optimal sequencing kernel association test were performed.
Results:
Of the 141 patients, 88 (62%) experienced PTS. There were 108 disease-causing variants in severely physically injured patients. As secondary findings, the stress- and inflammation-related signaling pathways were enriched in the PTS patients, while the glucose metabolism pathway was enriched in those without PTS. However, no significant PTS-related variants were identified.
Conclusion
Our findings suggest that genetic alterations in stress and inflammatory pathways might increase the likelihood of PTS immediately after severe physical injury. Future studies with larger samples and longitudinal designs are needed.

Background:
and Purpose Migraine is one of the most common chronic neurological diseases worldwide. Although diverse treatment regimens have been recommended, there is insufficient evidence for which treatment patterns to apply in routine clinical settings.
Methods:
We used nationwide claims data from South Korea for 2015–2021 to identify incident migraine patients with at least one prescription for migraine. Patients were categorized according to their initial treatment classes and followed up from the date of treatment initiation. Treatment regimens included prophylactic treatments (antidepressants, anticonvulsants, beta blockers, calcium-channel blockers, and renin-angiotensin-aldosterone system [RAAS] inhibitors) and acute treatments (acetaminophen, antiemetics, aspirin, ergotamine, nonsteroidal anti-inflammatory drugs [NSAIDs], opioids, and triptans). The treatment patterns of migraine were evaluated until the end of the study period, including the secular trends, prevalence, persistence, and changes in migraine treatment.
Results:
Among the 761,350 included patients who received migraine treatment, the most frequently prescribed acute treatment was an NSAID (69.9%), followed by acetaminophen (50.0%).The most-prescribed prophylactic treatment was flunarizine (36.9%), followed by propranolol (24.4%). Among the patients, 54.8% received acute treatment, 13.5% received prophylactic treatment, and 31.6% received both treatment types. However, 65.7% of the patients discontinued their treatment within 3 months. The 3-month persistence rate was highest for triptans (25.2%) among the acute treatments and for RAAS inhibitors (62.0%) among the prophylactic treatments.
Conclusions
While the prevalence rates of medication use were found to align with current migraine guidelines, frequent switching and rapid discontinuation of drugs were observed in routine clinical settings.

The nfa1 gene was cloned from a cDNA library of pathogenic Naegleria fowleri by immunoscreening; it consisted of 360 bp and produced a 13.1 kDa recombinant protein (rNfa1) that showed the pseudopodia-specific localization by immunocytochemistry in the previous study. Based on the idea that the pseudopodia-specific Nfa1 protein mentioned above seems to be involved in the pathogenicity of N. fowleri, we observed the effect of an anti-Nfa1 antibody on the proliferation of N. fowleri trophozoites and the cytotoxicity of N. fowleri trophozoites on the target cells. The proliferation of N. fowleri trophozoites was inhibited after being treated with an anti-Nfa1 polyclonal antibody in a dose-dependent manner for 48 hrs. By a light microscope, CHO cells co-cultured with N. fowleri trophozoites (group I) for 48 hrs showed severe morphological destruction. On the contrary, CHO cells co-cultured with N. fowleri trophozoites and anti-Nfa1 polyclonal antibody (1: 100 dilution) (group II) showed less destruction. In the LDH release assay results, group I showed 50.6% cytotoxicity, and group II showed 39.3%. Consequently, addition of an anti-Nfa1 polyclonal antibody produced a decreasing effect of in vitro cytotoxicity of N. fowleri in a dosedependent manner.

The authors report two cases of clozapine-induced acute hepatitis. Two patients developed asymptomatic hepatitis and got better with conservative care. We decreased the dosage of clozapine and added hepatic protectors, resulting in normalized laboratory findings. The authors also reviewed side effects of clozapine in this report. We reviewed the suggested mechanism of either clozapine or chlorpromazine-induced hepatitis. Clozapine influences the liver cell via cytochrome P 450 and chlorpromazine does so via mild cholestasis. There may be a possibility that a patient who has experienced drug-induced hepatitis is vulnerable to clozapine-induced acute hepatitis. In this respect, those who have experienced drug-induced hepatitis must be observed more closely.

BACKGROUND: The lateral radiograph-based system described by Tsuyama is used widely to classify ossification of the posterior longitudinal ligament (OPLL) of the cervical spine. However, OPLL is a complex 3-dimensional (3-D) lesion, not a simple and uniplanar one, which is often difficult to identify on a lateral radiograph. Furthermore, its reliability among spine surgeons has not been investigated. Given the popularity of a reconstructed computed tomography (CT), this study examined the inter- and intra-observer reliability of lateral radiograph-based OPLL classification using that modality. METHODS: Five spine surgeons independently reviewed the lateral radiograph, axial CT, 2-D (sagittal) and 3-D reconstructed CT images of 108 OPLL patients on 2 separate occasions. Based on these images, the reviewers classified each OPLL case according to the Tsuyama's system. The kappa values were used to assess the statistical reliability. RESULTS: The inter- and intra-observer kappa values were only 0.51 and 0.67 for the lateral radiograph, even in combination with the axial CT images, 0.70 and 0.85 for 2-D CT images, and 0.76 and 0.86 for 3-D CT images, respectively. These kappa values showed a good-to-excellent range for the 2-D and 3-D reconstructed CT images while those of the lateral radiograph indicated a fair range. According to the OPLL types, the inter- and intra-observer reliability was low in the continuous type and high in the circumscribed type on the lateral radiograph. However, the low reliability of the continuous type on lateral radiograph was overcome somewhat using 2-D and 3-D reconstructed CT images. CONCLUSIONS: The inter- and intra-observer kappa values were only 0.51 and 0.67 for the lateral radiograph, even in combination with the axial CT images, 0.70 and 0.85 for 2-D CT images, and 0.76 and 0.86 for 3-D CT images, respectively. These kappa values showed a good-to-excellent range for the 2-D and 3-D reconstructed CT images while those of the lateral radiograph indicated a fair range. According to the OPLL types, the inter- and intra-observer reliability was low in the continuous type and high in the circumscribed type on the lateral radiograph. However, the low reliability of the continuous type on lateral radiograph was overcome somewhat using 2-D and 3-D reconstructed CT images.

PURPOSE: In this study we evaluated the long-term outcomes and prognostic factors of trabeculectomy with mitomycin C (MMC) in eyes with uveitic glaucoma (UG) compared with primary open-angle glaucoma (POAG). METHODS: We performed a retrospective chart review of 60 eyes with UG and 402 eyes with POAG that were followed up for at least 1 year after trabeculectomy with MMC between June 2000 and December 2012. The review included intraocular pressure (IOP), number of anti-glaucoma medications, and postoperative complications. Surgical success was analyzed using the Kaplan-Meier life-table method based on 2 definitions of successful IOP control with topical anti-glaucoma medications: Definition A (IOP < or = 15 mm Hg) and Definition B (IOP < or = 18 mm Hg). Risk factors for surgical failure of trabeculectomy were analyzed using the Cox proportional hazards model. RESULTS: Success rate at 5 years after trabeculectomy was lower in UG than in POAG (65.8% vs. 76.4%, Definition B), but without significant difference. However, UG had a significantly lower cumulative probability of success than POAG based on Kaplan-Meier survival curves (p = 0.049 and 0.044, respectively). Postoperative hypotony and hypotony maculopathy was more frequent in UG (p = 0.044 and 0.044, respectively). In UG, the Cox proportional hazards model showed postoperative shallow anterior chamber was associated with surgical failure in both Definition A and B. CONCLUSIONS: Long-term results of trabeculectomy with MMC in eyes with UG showed successful IOP control similar to POAG. Trabeculectomy with MMC is a reasonable surgical option for the management of UG.
