Progressive Supranuclear Palsy Diagnosed After a Severe Fall Trauma in a Patient Who Experienced Episodes of Easy Falling.

Progressive supranuclear palsy (PSP) is characterized by parkinsonism, downward gaze disorder, and a tendency to fall due to degeneration of the basal ganglia, the brain stem, and the cerebellum. We report a case of PSP that was diagnosed following a traumatic hemopneumothorax caused by a fall while descending stairs. A 79-year-old man experienced lightheadedness and frequent falls for two years. He fell on stairs at home and was transferred to our hospital due to mobility issues. He was hospitalized and treated for traumatic hemopneumothorax. Neurological examination revealed vertical ocular motility disorder, positive Myerson's sign, increased muscle stiffness, and increased limb tendon reflexes. Brain MRI showed a hummingbird sign. In this case, a midbrain area of 58.1 mm2 was consistent with PSP. He had no medication history that could have caused falls. He was diagnosed with PSP based on clinical and imaging findings, and treatment with levodopa was initiated. Two months later, walking showed limited improvement, and living at home became difficult. He was discharged to a care facility. PSP is a risk factor for frequent falls in the elderly. PSP usually requires three to four years for diagnosis, although falls appear earlier than in other forms of degenerative parkinsonism. Additionally, PSP often results in repeated dynamic falls due to a decreased perception of danger associated with reduced frontal lobe function. As a result, the severity of trauma from falls in PSP tends to be higher than in other neurodegenerative diseases. Therefore, early diagnosis of PSP may help improve patients' quality of life and prevent trauma. Despite frequent falls over two years, the cause was not thoroughly investigated until the patient experienced severe trauma. The lesson from this case is the importance of a thorough neurological examination and sagittal MRI for elderly patients experiencing repeated falls, to consider the possibility of PSP. Furthermore, quantitative evaluation of MRI enhances the diagnostic accuracy of PSP.

A Case Report of Grave's Disease Presenting With an Episode of Restless Legs Syndrome.

This case report explores a rare presentation of restless legs syndrome (RLS) in a 59-year-old female with a history of Graves' disease (GD), highlighting the diagnostic challenges and the importance of considering thyroid dysfunctions in RLS. The patient, previously diagnosed and treated for GD, presented with acute nocturnal discomfort in her lower limbs, along with symptoms of fatigue, weight loss, and palpitations. Physical examinations and thyroid function tests indicated a recurrence of GD. Her RLS symptoms notably resolved following the treatment of GD with methimazole, pointing towards secondary RLS induced by GD. This case emphasizes the necessity of a comprehensive diagnostic approach in RLS, particularly in differentiating it from mimicking conditions including leg cramps, arthritis, peripheral neuropathy, and drug-induced akathisia, and identifying underlying etiologies like thyroid dysfunctions. The resolution of RLS symptoms after GD treatment underlines the potential link between thyroid dysfunctions, iron metabolism, and the dopaminergic system in RLS pathophysiology.

Response to regarding the case image article entitled "A case of angle-closure glaucoma caused by spontaneous lens dislocation" by Kondo et al.

The occurrence of acute angle closure with posterior displacement of the lens is rare compared with that of anterior dislocation; however, several studies have reported its occurrence.

Ulcerative sarcoidosis: An atypical cause of leg ulcers.

We present the case of an 83-year-old woman with leg ulcers who was diagnosed with sarcoidosis. This case highlights the importance for clinicians to consider ulcerative sarcoidosis when encountering patients with leg ulcers along with hilar adenopathy, uveitis, elevated serum angiotensin-converting enzyme, and histopathological findings of epithelioid cell granulomas.

Crowned dens syndrome: A case series of 72 patients at eight teaching hospitals in Japan.

Background: Crowned dens syndrome (CDS) is characterized by calcification around the odontoid process, accompanied by neck pain. Although CDS is supposedly rare, we regularly diagnose and manage this condition, indicating a perception gap between previous studies and our experience. The purpose of this study was to determine the annual incidence of CDS, time to diagnosis in CDS, as well as the features of CDS. Methods: The study design was a retrospective case series study conducted at eight teaching hospitals in Japan. We identified CDS cases from April 2013-March 2015. CDS was diagnosed when patients had acute onset of neck pain and CT showed calcification around the dens and when other diagnoses were unlikely. Results: Seventy-two CDS cases were identified. Mean annual incidence was 4.6 ± 2.3 cases at each hospital. Among those with available data, 57 of 64 had limited rotation (89.1%). The diagnosis of CDS was made in general internal medicine or the emergency medicine department in 61 cases (84.7%). A total of 62 cases (86.1%) were diagnosed within 1 day of presentation, and the median time from initial presentation at the hospital to diagnosis was 0.0 days (25th-75th percentiles, 0.0-1.0). For treatment, NSAIDs were used in 56cases (77.8%) and acetaminophen in 20 cases (27.8%). Conclusion: CDS might be more common than has been reported to date. Time to diagnosis of CDS was within 1 day of visiting a teaching hospital. Cervical motion restriction is common in CDS and may be useful in establishing the diagnosis.

A Case of Pseudohyperaldosteronism Induced by Yokukansan and Shakuyakukanzoto That Resulted in Severe Hypokalemia.

Pseudohyperaldosteronism can be induced by the excessive use of Chinese herbal medicines (Kampo medicines), resulting in serious disorders. We report a case of pseudohyperaldosteronism induced by two Kampo medicines which resulted in severe hypokalemia. A 70-year-old woman was hospitalized for a left calcaneal fracture. She had no subjective symptoms other than trauma. On her admission, blood test results revealed a low serum potassium level of 2.4 mmol/L by chance, as well as low levels of both renin and aldosterone. The patient had been taking 5 g of Yokukansan per day for the past three months. In addition, she was on 5 g Shakuyakukanzoto per day for three months until a month prior to hospitalization. The daily licorice content from the aforementioned herbs was 1.0 g and 4.0 g, respectively. After hospitalization, the administration of the Kampo medicines was discontinued, and 610 mmol of potassium was administered over a period of 13 days, which resulted in the normalization of serum potassium levels. Pre-existing hypertension slowly improved as well. Patients consuming licorice at doses of 2.5 g per day or more, as in our case, are at a high risk of developing pseudohyperaldosteronism. Furthermore, the risk is particularly high with long-term licorice consumption as well as for women and elderly patients. To this end, high-dose potassium supplementation may be necessary for normalizing serum potassium levels. Therefore, awareness regarding the adverse effects of licorice is crucial, even in cases of low dosages of licorice.

A case of superior mesenteric artery syndrome characterized by deep forward bending posture in a cross-legged position on the floor.

A 17-year-old healthy male presents with severe epicardial pain and frequent vomiting 1 h after lunch, preferring to sit cross-legged on a stretcher with a deep forward bending posture along with difficulty lying down. SMA syndrome should be considered in the differential diagnosis of patients demonstrating such posture.

Inclusion body myositis in an older patient following a fall.

After experiencing a fall, an 82-year-old woman developed progressive loss of lower limb strength and was diagnosed with inclusion body myositis. Although falls and muscle weakness are often regarded as consequences of aging, inclusion body myositis should be considered in a patient with a history of multiple falls.

A case of angle-closure glaucoma caused by spontaneous lens dislocation.

Spontaneous lens dislocation without genetic factors is rare. In this case, spontaneous lens dislocation occurred without an apparent trigger and resulted in secondary angle-closure glaucoma. A head computed tomography (CT) scan showed lens dislocation. It is critical to assess for lens dislocation during head CT scan for a sudden headache.

Accessory liver lobe in the right thoracic cavity.

A healthy 42-year-old man presented to the hospital because of chest radiography performed during a medical checkup revealed a tumor. Contrast-enhanced computed tomography showed a tumor of 5 cm diameter just above the right diaphragm with blood flow from the portal vein. The patient was diagnosed with accessory liver lobe (ALL). No finding suggested malignancy, and he is being followed up. ALLs are usually found in the abdominal cavity, but they can also be found in the thoracic cavity. Although ALL is rare, it should be considered in patients presenting with intrathoracic tumors.

Cytomegalovirus colitis with a new diagnosis of ulcerative colitis in an elderly woman.

Objectives: Cytomegalovirus (CMV) colitis is generally diagnosed in immunocompromised patients. It is rare for patients who are not immunocompromised to develop CMV colitis. Cases of CMV colitis in patients with inflammatory bowel disease have also been reported. We encountered a case of CMV colitis with a new diagnosis of severe ulcerative colitis and demonstrated the importance of suspecting ulcerative colitis in immunocompetent patients with CMV colitis. Patient: A 78-year-old woman was hospitalized with fever and diarrhea that had lasted for a month. Colonoscopy revealed continuous diffuse edema, mucosal redness, and multiple punched-out ulcers with bleeding, suggesting cytomegalovirus (CMV) colitis, although she was not immunocompromised. Immunohistochemical staining revealed CMV-positive cells, and CMV colitis was diagnosed. One month later, a colonoscopy was conducted owing to persistent symptoms despite initiating the prescribed antiviral drug. A complete loss of vascular pattern, easy bleeding of the crude mucosa, and exacerbation of multiple punched-out ulcers were observed. She was diagnosed with severe ulcerative colitis. The symptoms of ulcerative colitis disappeared with prednisolone and 5-amino salicylic acid treatment. Conclusion: Ulcerative colitis should be suspected in immunocompetent patients with CMV colitis.

A case of diabetic ketoacidosis with hemorrhagic gastric ulcer.

This is a case of diabetic ketoacidosis with hemorrhagic gastric ulcer. Mortality rates increase when DKA is complicated with upper gastrointestinal bleeding, so it is important to consider this possibility.

A Case of Acute Focal Bacterial Nephritis With Negative Pyuria and Urine Culture Test Results.

Acute focal bacterial nephritis (AFBN) is a radiologically diagnosed acute localized kidney infection that appears in the continuum between a perinephric abscess and renal abscess. We report an unusual case of AFBN presenting without pyuria or positive urine cultures. A 42-year-old woman with chronic lower back pain who regularly used nonsteroidal anti-inflammatory drugs was admitted to our hospital with right-sided abdominal distention, fever, chills, and pain extending from the right lower abdomen to the back since two days. The physical examination revealed no abdominal or costovertebral angle tenderness. Urinalysis was negative. Abdominal ultrasound was notable for an indistinct nodular shadow (32 × 25 mm) on the upper pole of the right kidney. Abdominal contrast-enhanced computed tomography revealed a wedge-shaped area with a minimal uptake of the contrast in the right kidney. The patient was admitted to the hospital, and antimicrobial therapy was started for AFBN. Antibiotics were administered intravenously for one week and orally for two weeks. No relapse of symptoms was observed during the four-month follow-up period. This case report suggests the importance of considering AFBN as a differential diagnosis for cases of idiopathic fever and lateral pain or back pain, even when pyuria and urine culture test results are negative.

A Case of Pyometra Caused by Achromobacter xylosoxidans and γ-Streptococcus in an Elderly Frail Woman.

Pyometra is an easily overlooked disease with nonspecific symptoms; however, a delayed diagnosis can lead to severe complications. An 80-year-old frail woman presented to our hospital with a chief complaint of persistent fever for 10 days. Her blood tests showed an elevated inflammatory response, and computed tomography showed a 10-cm cystic lesion in the pelvic floor compressing the bladder. A catheter was inserted from the vagina into the uterine cavity, resulting in pus drainage and pyometra diagnosis. A pus culture was subsequently performed, which detected Achromobacter xylosoxidans, a common cause of respiratory tract infections in cystic fibrosis and bloodstream infections, andγ-streptococcus. To the best of our knowledge, this is the first report of pyometra caused by Achromobacter xylosoxidans. The patient was treated with drainage and piperacillin-tazobactam administration. Pyometra is especially prevalent in older women with impaired activities of daily living and dementia. Although fever, lower abdominal pain, and increased discharge may occur, symptoms are often nonspecific, and half of such cases are asymptomatic. Furthermore, delayed diagnosis can lead to perforation of the uterus and consequent pan-peritonitis. Thus, the diagnosis of pyometra should be considered in older women presenting with unknown fever, and imaging studies and gynecological consultation should be requested promptly.

Small bowel obstruction of barium for gastric cancer screening.

We report a case of small bowel obstruction without perforation and peritonitis caused by inspissated barium sulfate for gastric cancer screening and surgically treated 26 hours after the onset of abdominal pain.

A case of severe pneumonia with viremia caused by adenovirus B7 identified by off-label use of a multiplex PCR system.

Severe infection with human adenovirus (HAdV) is uncommon in adults, and the lack of reliable point-of-care testing makes the diagnosis challenging. A 39-year-old immunocompetent Indian man developed severe pneumonia, and his condition became life-threatening despite antimicrobial therapy. While sputum and blood cultures remained negative, a multiplex PCR respiratory panel (Filmarray Respiratory Panel), which is only approved for use with nasopharyngeal samples, detected HAdV in the serum and tracheal aspirates on day 5. We therefore initiated ganciclovir, steroids, and intravenous immunoglobulin. The patient's respiratory condition improved significantly, and he eventually recovered without complications. We later confirmed that conventional PCR of serum detected HAdV-B7. Our case illustrated that a respiratory panel using multiplex PCR successfully detected HAdV in unapproved samples. Such off-label analyses may support the early diagnosis of infections caused by pathogens that are difficult to identify by routine microbiological examination.

Electrical storm 11 days after acute myocardial infarction: a case report.

BACKGROUND: The definition of electrical storm is still debated. For example, an electrical storm is defined as a clustering of three or more separate episodes of ventricular tachycardia/ventricular fibrillation within 24 hours or one or more episodes occurring within 5 minutes of termination of the previous episode of ventricular tachycardia/ventricular fibrillation. When it is refractory to medications, prompt assessments by coronary angiography, sedation, and overdrive pacing should be performed. An electrical storm may occur anytime, including at night or after the patient leaves an intensive care unit. CASE PRESENTATION: A 70-year-old Japanese man with type 2 diabetes mellitus was diagnosed as having ST-elevation myocardial infarction. His clinical course after an urgent percutaneous coronary intervention was uneventful, but he developed electrical storm that was refractory to antiarrhythmic medications on day 11 of hospitalization. We used sedative medications and performed ventricular overdrive pacing and transferred him to a university hospital for further treatment, which included electrical ablation and cardioverter-defibrillator implantation. CONCLUSION: An electrical storm is a relatively rare and fatal complication of acute myocardial infarction. It is important that the treatment choices for this condition are known by non-cardiologist physicians who might encounter this rare condition.

Clinical significance of reversed R wave progression in right precordial leads.

Objective: Poor R wave progression in right precordial leads is a relatively common electrocardiogram (ECG) finding that indicates possible prior anterior myocardial infarction (MI); however, it is observed frequently in apparently normal individuals. In contrast, reversed R wave progression (RRWP) may be more specific to cardiac disorders; however, the significance of RRWP in daily clinical practice is unknown. The purpose of this study was to clarify the significance of RRWP in clinical practice. Materials and Methods: We analyzed consecutive ECGs obtained from 12,139 patients aged ≥20 years at Mito Kyodo General Hospital in Ibaraki between November 2009 and August 2012. Our setting is a secondary emergency hospital in the community, and the study participants were inpatients or patients who visited the general or emergency outpatient departments. RRWP was defined as RV2 < RV1, RV3 < RV2, or RV4 < RV3. Regarding ECGs considered to show RRWP, we confirmed the presence or absence of an abnormal Q wave and whether ultrasound cardiography, contrast-enhanced computed tomography, coronary angiography, and/or left ventriculography were performed to obtain detailed information. Results: RRWP was identified in 34 patients (0.3%). Among these patients, 29 (85%) had undergone cardiac evaluation. The final diagnosis was previous anterior MI in 12 patients (41%) and ischemic heart disease (IHD) without MI in 5 patients (17%). All 17 patients with IHD had left anterior descending (LAD) artery stenosis. The other patients were diagnosed with dilated (two patients, 7%) and hypertrophic (one patient, 3%) cardiomyopathy, left ventricular hypertrophy (one patient, 3%), or pulmonary embolism (one patient, 3%). Only seven patients (24%) were normal. Conclusions: RRWP is rare in daily clinical practice; however, it is a highly indicative marker for cardiac disease, particularly IHD with LAD artery stenosis.

Development of polymyalgia rheumatica during hospitalization and diagnosis based on history taking by physical and occupational therapists.

Polymyalgia rheumatica (PMR) is frequently reported in the outpatient setting and presents with pain, morning stiffness, mild fever, and fatigue. However, the clinical course of PMR during hospitalization is unknown. We report a case of PMR that developed during hospitalization. PMR diagnosis should begin with an evaluation of core inclusion and exclusion criteria. However, when examining elderly patients, retrieving symptom information from the patient or their family is often difficult, especially during prolonged hospitalization. History taking by physical and occupational therapists or by other health care professionals is paramount in the symptomatic diagnoses of inpatients.
