Hydrocephalus owing to ventriculoperitoneal shunt dysfunction.

A 43-year-old woman presented to our hospital with headache accompanied with nausea and intermittent vomiting without abdominal pain. The patient had undergone ventriculoperitoneal shunt placement for hydrocephalus owing to quadrigeminal cistern arachnoid cyst. Cranial computed tomography demonstrated enlarged bilateral ventricles, and the abdominal radiograph demonstrated a reverse U-shaped catheter that seemed to have been fractured in the left peritoneal cavity.

Characteristic target sign of the small intestine in a case of lupus enteritis.

A 30-year-old woman was admitted to our hospital complaining of intermittent severe abdominal pain. Her laboratory examinations revealed positive serology for antinuclear antibody titer of 1:640 (reference < 40), double-stranded DNA antibody, anti-Smith antibody, and anti-RNP antibody. A contrast-enhanced computed tomography demonstrated slight ascites and a characteristic target sign, suggesting lupus enteritis.

Small intestinal press-through package perforation.

A 75-year-old man had worsened abdominal pain. Contrast-enhanced computed tomography revealed wall thickness in the terminal ileum with peritonitis. A round, high-density object surrounded by a low-density area, which is a characteristic computed tomography finding for a tablet in a press-through package, was observed in the terminal ileum.

Double-wall sign because of intestinal perforation.

This study sought to describe the case of an 86-year-old man who presented to our hospital complaining of abdominal pain, abdominal distention, and loss of appetite for 4 days prior. This case suggests that an amount of accumulated air clearly highlights the intestinal wall, like a "double-wall sign," even when the patient is standing.

Recent Outpatient Services in General Internal Medicine: 6.4% of Symptomatic Patients Were Post-Acute COVID-19.

PURPOSE: It is important to understand how COVID-19 is affecting general outpatient services, since hospitals see a wide variety of patients. This study aimed to evaluate the incidence and clinical picture of COVID-19 in general outpatient services. Currently, the diagnosis of COVID-19 depends strongly on the results of polymerase chain reaction (PCR) assays. However, since the sensitivity of PCR tests for SARS-CoV-2 is not high enough to assure confidence. On the other hand, the SARS-CoV-2 antibody (Ab) test is highly sensitive after 2 weeks of symptom onset, and might complement the PCR test. Therefore, we measured Ab in addition to PCR to obtain a more accurate clinical profile of COVID-19, which might be helpful in building future practice strategies. PATIENTS: The study patients were those who visited our department for the first time between November 2020 and March 2021 and fulfilled the enrolment criteria. METHODS: All patients underwent total SARS-CoV-2 Ab testing, and PCR tests were performed in only some of them; patients were classified according to the performance of PCR tests for comparisons. RESULTS: Ninety-four patients who underwent Ab testing during the study period were eligible for study enrolment, and the PCR test was performed in 40 of them. Only one patient was diagnosed with acute stage COVID-19 based on a positive PCR test. Antibodies were positive in six (6.4%) of the 94 patients. Five of the six Ab-positive patients were negative for PCR, and the test was not performed in the sixth patient. All the six patients had prior symptoms suggestive of infection, and respiratory symptoms were more noticeable than fever. The Ab positivity rate was significantly higher than published data. CONCLUSION: COVID-19 is not rare in general outpatient services and can be missed based on PCR tests alone. The diagnosis should be made from a comprehensive perspective.

The Use of Oral Herbal Medicine (Hange-Shashin-To) in Patients with Pouchitis: A Pilot Study.

OBJECTIVES: Hange-Shashin-To (HST), which is a combination of seven herbs, has previously been used in the treatment of inflammatory or ulcerative gut disease. The aim of this study was to evaluate the safety and efficacy of HST for the treatment of chronic pouchitis. METHODS: Nineteen patients with chronic pouchitis, defined as either frequent episodes (≥ three episodes per six months) of pouchitis or persistent symptoms that required continuous antibiotic therapies, were selected and treated with ciprofloxacin (CPFX) 600 mg/day for 2 weeks (week 0~2) and HST 3,750 mg/day for 32 weeks (week 0~32). The Pouchitis Disease Activity Index (PDAI) score was measured at week 0 and 6 for short-term evaluation. For long-term evaluation, total CPFX dose in the 26-week period prior to study entry (from 30 weeks before study entry to 5 weeks before study entry) was compared with the total CPFX dose during the 26-week study period (week 7~32). Although no concomitant administration of CPFX was permitted from week 2-6, patients whose condition deteriorated were prescribed CPFX from week 7 to week 32. RESULTS: Fourteen patients completed this 32-week study. The PDAI scores of eight patients decreased below seven. The mean total PDAI scores decreased significantly from 11 ± 2.5 to 6.5 ± 2.5 (P < 0.001). The mean value of total CPFX dose decreased significantly from 491.6 ± 182.4 mg/kg to 392.5 ± 184.0 mg/kg (P < 0.05). No severe adverse events were noted. CONCLUSIONS: Our data suggest that HST has a positive effect on chronic pouchitis with no adverse effects.

Pulmonary and gastric metastatic calcification due to milk-alkali syndrome: a case report.

The incidence of metastatic calcification is influenced by high serum calcium and phosphate concentrations and local physicochemical conditions, such as pH. A high pH accelerates tissue calcification. Patients with milk-alkali syndrome typically present with renal failure, hypercalcemia, and metabolic alkalosis, which are caused by the ingestion of calcium and absorbable alkali. Among patients with impairment of renal function, milk-alkali syndrome is a major cause of hypercalcemia. Long-term use of furosemide will lead to hypokalemia, metabolic alkalosis, and eventually renal failure (i.e., pseudo-Bartter syndrome). Even if the level of calcium ingestion is relatively low, the renal failure caused by long-term furosemide use can readily lead to milk-alkali syndrome. We describe a case of a 45-year-old woman who was admitted with cough and dyspnea and presented with pulmonary and gastric metastatic calcification. She had been taking alfacalcidol and oral alkaline medications such as sodium bicarbonate and calcium carbonate as well as oral furosemide for a long time. The patient was found to have hypercalcemia, chronic renal failure, and metabolic alkalosis, so milk-alkali syndrome was diagnosed. Saline was administered and oral medications were discontinued. Serum creatinine levels subsequently decreased, but pulmonary metastatic calcification was not diminished. In this case, the milk-alkali syndrome that caused the severe metastatic calcification was exacerbated by multiple factors, including oral alkaline medications such as sodium bicarbonate and calcium carbonate. In addition, metabolic alkalosis and renal failure were affected by long-term furosemide use (i.e., pseudo-Bartter syndrome).

Churg-Strauss syndrome concomitant with chronic symmetrical dacryoadenitis suggesting Mikulicz's disease.

A case of Churg-Strauss syndrome complicated by chronic symmetrical dacryoadenitis suggestive of Mikulicz's disease is herein presented. A 72-year-old Japanese man, who had been previously diagnosed with asthma, presented with weakness of the left leg and purpura on the lower extremities. A neurological examination showed multiple mononeuropathies and a laboratory examination revealed elevated eosinophil counts, IgE levels and the presence of Myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCAs). Churg-Strauss syndrome was diagnosed, although the patient also exhibited bilateral swelling of the lachrymal glands. Furthermore, elevated serum IgG4 levels, an infiltration of a relatively large number of IgG4-positive plasmacytes in the nasal mucosa and hypocomplementemia were also observed. These findings were consistent with a diagnosis of Mikulicz's disease (MD). Oral prednisolone (30 mg) was administered and the swelling of the lachrymal glands resolved. Churg-Strauss syndrome may be accompanied by Mikulicz's disease (an IgG4-related disease), and common pathogeneses between Churg-Strauss syndrome and IgG4-related disease may exist.

Usefulness of a semi-quantitative procalcitonin test and the A-DROP Japanese prognostic scale for predicting mortality among adults hospitalized with community-acquired pneumonia.

BACKGROUND AND OBJECTIVE: The solid-phase immunoassay, semi-quantitative procalcitonin (PCT) test (B R A H M S PCT-Q) can be used to rapidly categorize PCT levels into four grades. However, the usefulness of this kit for determining the prognosis of adult patients with community-acquired pneumonia (CAP) is unclear. METHODS: A prospective study was conducted in two Japanese hospitals to evaluate the usefulness of this PCT test in determining the prognosis of adult patients with CAP. The accuracy of the age, dehydration, respiratory failure, orientation disturbance, pressure (A-DROP) scale proposed by the Japanese Respiratory Society for prediction of mortality due to CAP was also investigated. Hospitalized CAP patients (n = 226) were enrolled in the study. Comprehensive examinations were performed to determine PCT and CRP concentrations, disease severity based on the A-DROP, pneumonia severity index (PSI) and confusion, urea, respiratory rate, blood pressure, age ≥65 (CURB-65) scales and the causative pathogens. The usefulness of the biomarkers and prognostic scales for predicting each outcome were then examined. RESULTS: Twenty of the 170 eligible patients died. PCT levels were strongly positively correlated with PSI (ρ = 0.56, P < 0.0001), A-DROP (ρ = 0.61, P < 0.0001) and CURB-65 scores (ρ = 0.58, P < 0.0001). The areas under the receiver operating characteristic curves (95% CI) for prediction of survival, for CRP, PCT, A-DROP, CURB-65, and PSI were 0.54 (0.42-0.67), 0.80 (0.70-0.90), 0.88 (0.82-0.94), 0.88 (0.82-0.94), and 0.89 (0.85-0.94), respectively. The 30-day mortality among patients who were PCT-positive (≥0.5 ng/mL) was significantly higher than that among PCT-negative patients (log-rank test, P < 0.001). CONCLUSIONS: The semi-quantitative PCT test and the A-DROP scale were found to be useful for predicting mortality in adult patients with CAP.

A case of Wegener's granulomatosis associated with progressive dysphagia owing to esophageal involvement.

A 52-year-old woman was admitted to our hospital with progressive dysphagia. Upper gastrointestinal endoscopy revealed esophageal stenosis and computed tomographic scan revealed symmetrical wall thickness of the thoracic esophagus. Biopsies findings from a lesion were unremarkable. However, a definitive diagnosis of Wegener's granulomatosis was based on positive anti-neutrophil cytoplasmic antibodies directed against proteinase 3 and otorhinolaryngological manifestations. Esophageal complications are rarely reported in Wegener's granulomatosis; however, clinicians should be aware of the possibility of esophageal involvement.

Thrombotic microangiopathy due to malignant hypertension following corticosteroid therapy for microscopic polyangitis.

A 78-year-old woman was treated with 40 mg of prednisolone for microscopic polyangitis, and favorable effects were observed. However, her blood pressure increased and she developed severe thrombocytopenia. Thrombotic microangiopathy (TMA) due to malignant hypertension was suspected and she was treated with an angiotensin-converting enzyme inhibitor; her platelet count then rose. She showed a close temporal relationship between initiation of corticosteroid therapy and the onset of TMA. Corticosteroid therapy should be used with caution in patients with underlying vascular endothelial damage.

Phosphaturic mesenchymal tumor with symptoms related to osteomalacia that appeared one year after tumorectomy.

A 45-year-old man was admitted to our hospital because of bone pain and hypophosphatemia. He had undergone surgery 2 years previously for a "benign unclassified mesenchymal tumor" in the skull, but there were no clinical symptoms related to osteomalacia. His laboratory examination revealed low serum phosphate, high alkaline phosphatase, and normal calcium levels. The diagnosis of tumor-induced osteomalacia due to phosphaturic mesenchymal tumor mixed connective tissue variant (PMTMCT) was made by re-examining the pathologic specimens. Oral supplementation with phosphate and 1-25-dihydroxyvitamin D relieved his clinical symptoms and laboratory values returned to normal. However, subcutaneous administration of octreotide had no clinical effect. Clinicians and pathologists should be aware of the existence of PMTMCT especially nonphosphaturic or asymptomatic variants of this disorder.
