Anastomosis of the Left Juxtaposed Atrial Appendages in a Patient With Tricuspid Atresia

A 9-month-old boy with left juxtaposition of the atrial appendages, tricuspid atresia, pulmonary atresia, and ventriculoarterial discordance underwent anastomosis between the atrial appendages after failure of balloon/blade atrial septostomy because of restrictive atrial septal defect. For surgical creation of atrial communication in patients with juxtaposed atrial appendages, anastomosis between the atrial appendages seemed to be safer, more effective, and less invasive than septectomy by Blalock-Hanlon technique or inflow occlusion technique.     

Low-Grade Endometrial Stromal Sarcoma with Cardiovascular Involvement—A Report of Three Cases

Background. In low-grade endometrial stromal sarcoma, it has been reported that vascular space involvement in surgical specimens is found in over 50% of patients. However, in contrast to intravenous leiomyomatosis, it has been thought that further tumor extension to large vessels is rarely observed.Cases. We present three cases of low-grade endometrial stromal sarcoma with cardiovascular involvement by recurrent tumors observed on imaging studies. Two cases demonstrated tumor infiltration inside the inferior vena cava while the other case showed tumor growth in the left ventricle.Conclusion. This report suggests that attention should be paid to the possibility of cardiovascular invasion during the entire course of this disease.     

Clinical trial of in-situ hybridization method for the rapid diagnosis of sepsis

We evaluated the utility of in-situ hybridization (ISH) for the rapid diagnosis of sepsis. We applied this approach to polymorphonuclear neutrophil (PMN)-rich smears from patients with suspected bacterial infection. Positive results by ISH were obtained in the smears of 123 of 292 patients (42%), while only 32 of the 292 (11%) were positive by blood culture. These findings indicate that ISH is almost four times more sensitive than the culture method for the detection of sepsis. ISH results are obtained within 1 day, while 1 day to 2 weeks is required for the results of blood culture. Blood culture and ISH methods detected the same bacteria in two patients. ISH also successfully identified the same bacteria in blood and PMN-rich body fluid (bronchoalveolar lavage samples) in 6 patients. In 19 patients, ISH of blood detected the same bacteria as those found in subcultures from other sources (e.g., stool, sputum, nasal cavity). We discuss these results in comparison with blood culture results in terms of evaluating a rapid approach to the management of patients with sepsis.

Successful management of intractable epilepsy with intravenous lidocain and lidocain tapes.

The authors report on the successful management of a 6-year-old male with intractable epilepsy using intravenous lidocaine and lidocaine tapes. At 4 years of age, he developed psychomotor deterioration and intractable epilepsy associated with leukoencephalopathy secondary to the treatment of central nervous system leukemia. His seizures were refractory to conventional antiepileptic drugs. The adjunct treatment with intravenous lidocaine and lidocaine tapes proved effective in controlling the intractable seizures. Mental state and motor activity subsequently began to improve after the reduction of the seizures.     

Glomerulonephritis without IgA deposits in a case of Henoch-Schönlein purpura

A boy aged 3 years 8 months with Henoch-Schönlein purpura (HSP) developed significant proteinuria with hematuria 2 days after the appearance of purpura rash. Although thought to be purpura nephritis, a percutaneous renal biopsy revealed diffuse mesangial proliferative glomerulonephritis (MesPGN) without deposition of immunoglobulin A or complement. Since his urine screening test during a health check at the age of 3.5 years had been unremarkable, HSP might have played a role in the pathogenesis of his non-IgA MesPGN. To our knowledge, non-IgA MesPGN is an uncommon renal manifestation of HSP.     

Echocardiographic evaluation of the ductal morphology in patients with refractoriness to lipo-prostaglandin E1 therapy

BACKGROUND: Lipo-prostaglandin (PG)E1 is effective at lower doses and has fewer side effects than PGE1-cyclodextrin (CD). Previous studies, however, have suggested that some patients show refractoriness to lipo-PGE1 in the course of treatment. The present paper examines: (i) whether such cases can be predicted by examining the ductal morphology before and 24 h after the start of lipo-PGE1 infusion; and (ii) whether PGE1-CD dilates the ductus arteriosus in patients with refractoriness to lipo-PGE1. METHODS: The ductal morphology was evaluated with two echo indices, such as minimal and minimal plus maximal intraluminal diameters of the ductus. Two-dimensional echocardiography was performed in 24 patients with ductus-dependent congenital heart disease. The two echo indices were measured before and 24 h after lipo-PGE1 infusion and also at least twice per week until surgery. RESULTS: In 19 of 24 patients, ductal patency was maintained until surgical treatment (group A). The remaining five patients (21%) showed ductal closure during the course of the lipo-PGE1 therapy (group B). There were no significant differences between the two groups, in either the maximal or minimal diameters, which were examined before and 24 h after treatment. In the five patients of group B, lipo-PGE1 was replaced with a relatively high dosage of PGE1-CD (50-100 ng/kg per min), resulting in good ductal patency until surgery. CONCLUSIONS: Patients with refractoriness to lipo-PGE1 therapy could not be predicted from initial intraluminal diameters of the ductus using echocardiography. Therefore, serial echocardiographic examinations are important to detect early findings of ductal closure. In addition, PGE1-CD is still useful as back-up therapy in such patients.     

Clinico-radiologic Characteristics of Pulmonary Visceral Larva Migrans Caused by Ascaris suum

Objective Visceral larva migrans (VLM) caused by Ascaris suum is a major health problem in pig farming regions. The clinical characteristics of pulmonary VLM caused by A. suum, however, are unclear. We assessed the clinico-radiologic features of this disease. Methods Medical records, including the results of chest radiography and high-resolution computed tomography (HRCT), were retrospectively reviewed from January 2000 through June 2019, at the University of Miyazaki Hospital and Kyoritsuiin Hospital in Miyazaki Prefecture, Japan. Results Seven patients with VLM caused by A. suum were identified. All seven patients had a unique habit of consuming raw foods, such as organic vegetables, chicken, turkey, wild boar, and venison. All but one patient, who had eosinophilic pneumonia with a fever and severe fatigue, had only mild or no respiratory symptoms. All 7 patients had remarkable eosinophilia (median, 1,960 /μL) and high serum IgE levels (median, 1,346 IU/mL). Chest HRCT revealed multiple nodules and multiple nodular ground-glass opacities in 57% and 29% of the patients, respectively. The pulmonary lesions were located predominantly in subpleural areas. All seven patients were treated with albendazole, which led to improvement within two to three months. Neither eggs nor parasites were detected in the feces or sputum of any patient. Conclusion Consumption of raw organic vegetables or raw meat is a possible route of A. suum infection. Infected patients exhibit mild respiratory symptoms, and multiple nodules with a halo in the subpleural area are a common finding on chest HRCT. Treatment with albendazole was effective in these cases.     

Clinical Safety and Tolerability of A2NTX,a Novel Low-Molecular-Weight Neurotoxin Derived from Botulinum Neurotoxin Subtype A2, in Comparison with Subtype A1 Toxins

All the botulinum type A neurotoxins available for clinical use are of the A1 subtype. We developed a subtype A2 low-molecular-weight (150 kD (kilo Dalton)) neurotoxin (A2NTX) with less spread and faster entry into the motor nerve terminal than A1 in vitro and in vivo. Preliminary clinical studies showed that its efficacy is superior to A1 toxins. We conducted an open study exploring its safety and tolerability profile in comparison with A1LL (LL type A1 toxin, or onabotulinumtoxinA) and a low-molecular-weight (150 kD) A1 neurotoxin (A1NTX). Those who had been using A1LL (n = 90; 50–360 mouse LD50 units) or A1NTX (n = 30; 50–580 units) were switched to A2NTX (n = 120; 25–600 units) from 2010 to 2018 (number of sessions ~27, cumulative doses ~11,640 units per patient). The adverse events for A2NTX included weakness (n = 1, ascribed to alcoholic polyneuropathy), dysphagia (1), local weakness (4), and spread to other muscles (1), whereas those for A1LL or A1NTX comprised weakness (n = 2, A1NTX), dysphagia (8), ptosis (6), local weakness (7), and spread to other muscles (15). After injections, 89 out of 120 patients preferred A2NTX to A1 for the successive sessions. The present study demonstrated that A2NTX had clinical safety up to the dose of 500 units and was well tolerated compared to A1 toxins.     

Intramembrane structure of the sensory axon terminals in bullfrog muscle spindles

Much physiologic and morphologic research has been done into the sensory mechanism of the frog muscle spindle. However, no freeze-fracture study has described in detail the shape and intramembrane structure of the nonmyelinated sensory axon terminals of the frog muscle spindle. In this study, muscle spindles were isolated from the red part of bullfrog semitendinous muscles. Chemically fixed spindles were subjected to freeze fracturing. The sensory axon endings were reconstructed, and the size and density of intramembrane particles (IMPs) were measured along the sensory nerve endings. The axon terminals had four distinctive parts: parent trunks (>0.5 μm in diameter), primary branches (0.15–0.5 μm), terminal branches (<0.1 μm), and varicosities (0.02–0.5 μm). IMPs ranged from 5 nm to 21 nm in diameter and were present in the intramembrane space of the plasma membrane all throughout the nonmyelinated sensory nerve endings. Mean IMP sizes in the protoplasmic face (PF) and the external face (EF), respectively, were 8.1 nm and 8.4 nm in the parent trunks, 8.8 nm and 8.8 nm in the primary branches, 9.4 nm and 9.0 nm in the varicosities, and 8.7 nm and 8.7 nm in the terminal branches. Mean IMP size in the PF was smallest in the parent trunk and largest in the varicosity. Mean IMP densities (numbers of IMPs per μm²) in the PF and the EF, respectively, were 2,500 and 700 in the parent trunks, 2,200 and 500 in the primary branches, 1,700 and 400 in the varicosities, and 1,000 and 300 in the terminal branches. Density decreased with the tapering of the axon terminal, with IMPs distributed evenly in the PF and the EF. The characteristic intramembrane structure of sensory nerve endings is discussed. Anat.

Overexpression of cyclin D1 and p53 associated with disease recurrence in colorectal adenocarcinoma

Multiple genetic changes occur during the evolution of normal cells into cancer cells. It has been reported that both cyclin D1 and p53 genes play major roles in oncogenesis and/or cell cycle control in various cancers. In this study, we examined the overexpression of cyclin D1 and p53 by the immunohistochemical method and investigated the correlation between expression of these antigen and prognosis in patients with colorectal adenocarcinoma. Disease-free survival was significantly lower in the patients with cyclin D1-strongly positive tumors than in those with cyclin D1-negative tumors. Similarly, disease-free survival of the patients with p53-strongly positive tumors was significantly lower than that of those with p53-negative tumors. Moreover, multivariate analysis indicated that both cyclin D1 and p53 overexpression are independent prognostic factors in patients with colorectal adenocarcinoma. In conclusion, both cyclin D1 and p53 overexpression may be useful predictors of disease recurrence in patients with colorectal adenocarcinoma. Int. J. Cancer 74:310-315, 1997. © 1997 Wiley-Liss, Inc.
