Clinical evaluation of a new oral cephem, cefdinir, in children

Cefdinir (CFDN, FK482) was evaluated for its safety, efficacy and pharmacokinetics in 28 children. CFDN was effective in 100% of 22 evaluable cases with respiratory, middle ear, urinary or soft tissue infections. From the clinical response, adverse effects and the pharmacokinetic results, daily dose of 9-18 mg/kg, administered in 3 divided portions is suggested. Increase of dose will be associated with increase of gastrointestinal side effects. The data suggest that CFDN is safe and effective when used in children with infections caused by susceptible bacteria including Staphylococcus aureus.     

A case of double cancer: renal cell carcinoma and transitional cell carcinoma of urinary bladder

This is a case report on a patient with double cancer of kidney and urinary bladder. The patient was a 65-year-old female, and she was admitted with the chief complaint of gross hematuria and right flank pain. After careful examinations, she was diagnosed with right nonfunctioning kidney caused by invasive bladder cancer. Computerized tomography incidentally revealed a mass in the upper pole of the left kidney. Selective left renal arteriography showed stretched arteries and irregularity and tortuosity of the smaller vessels. She was diagnosed with double cancer of bladder and left kidney. Owing to the damage of the right renal function, left partial nephrectomy, total cystectomy, right nephroureterectomy and left ureterocutaneostomy were performed. According to DMSA scintigraphy measured 15 days later, the uptake value of the left kidney was 13.25%, compared to the preoperative value of 25.62%. To date, this case is 36th reported case in Japan.     

A case of granulocyte-colony stimulating factor producing gastric cancer]

We report a case of granulocyte-colony stimulating factor producing gastric cancer with multiple liver metastases. A 68-year-old woman who complained of epigastralgia visited our hospital. Upper gastrointestinal endoscopic examination revealed a type-2 gastric cancer. The laboratory data at admission indicated leukocytosis (35,900/microl) and a high level of serum granulocyte-colony stimulating factor (61 pg/mg). Granulocyte-colony stimulating factor producing gastric cancer was diagnosed by immunohistochemistry of biopsy specimen. Since we detected multiple liver metastases, chemotherapy was performed. Granulocyte-colony stimulating factor-producing gastric cancer is relatively rare and we summarize previous reports.     

Surgical treatment of acquired tricuspid stenosis]

There is no definitive surgical procedure for acquired lesions of the tricuspid valve (TV). From Feb, 1978, through March, 1990, the surgical treatment for the organic lesions of TV was performed in 10 patients, repair in 6 and TV replacement in 4. TV was repaired by commissurotomy, annuloplasty or valvuloplasty, or combination of them. When residual significant tricuspid regurgitation (TR) and/or stenosis (TS) was detected by intraoperative pulsed Doppler echocardiography after reparative procedures, TV was replaced. Follow-up periods ranged from 1 to 12 years (mean, 45.3 months). There was no early death, and late death was noted in one patient 32 months after operation. Preoperatively, 7 patients were in NYHA class IV and 3 in class III. Out of survivors, 7 are in class I and 2 in class II because of progression of mitral stenosis or coronary artery disease. Following surgery, the patients exhibited significant decrease in the cardiothoracic ratio (69.3 +/- 7.2 to 56.9 +/- 6.4%; p less than 0.01) and in the mean right atrial pressure (11.4 +/- 3.6 to 8.6 +/- 3.1 mmHg; p less than 0.05). The postoperative right ventriculography showed mild to moderate TR in 3 of 6 patients who underwent TV repair. In conclusion, TV repair could be a reasonable procedure for the organic TV lesions, although careful follow-up is recommended for residual TR.     

Bilateral reverse U incisions and separately placed columella relaxation incision for correction of bilateral cleft lip nose deformity

The reverse U incision method has been employed for the correction of the unilateral cleft lip nose deformity for more than twenty years with satisfactory results. It has some columella lengthening effect and thus has proved to be useful for the correction of nasal deformities of bilateral cleft lip. To augment its columella lengthening effect a columella relaxation incision is added to the bilateral reverse U incision for the correction of the bilateral cleft lip nose deformity. This results in a reconstructed columella of satisfactory length and width.     

Successful surgical treatment of secondary kwashiorkor after total gastrectomy: Report of a case

We report herein the case of a 56-year-old woman who developed secondary Kwashiorkor 9 years after undergoing a total gastrectomy for early gastric cancer. Until she began developing the symptoms of Kwashiorkor, including general fatigue, edema of the face and extremities, anemia, alopecia, and weight loss, she had been leading a normal life post-gastrectomy. Her symptoms were alleviated by total parenteral nutrition (TPN) therapy, but reappeared soon after TPN therapy was discontinued. Therefore, she required several subsequent courses of TPN. In an attempt to permanently resolve the ongoing Kwashiorkor symptoms, reconstructive surgery involving transposition of the jejunum from the previous Graham method to the interposition method was performed 10 years after the initial gastrectomy. After the second operation, her malnutrition was completely alleviated, and she has been in good health for the 8 years since. To our knowledge, there has been no other report of the symptoms of secondary Kwashiorkor after total gastrectomy being alleviated by altering the procedure of reconstruction of the intestinal tract. Thus, we recommend surgical treatment to alter the digestive continuity to a more physiological pathway for selected patients with secondary Kwashiorkor syndrome.     

Tracheal dilatation by halothane and enflurane in man

The effect of halothane and enflurane on tracheal tone were studied in 21 patients during the induction of anesthesia. Endotracheal tube cuff pressure was used to measure tracheal tone. Anesthesia, maintained by nitrous oxide 70% in oxygen, was supplimented with succinylcholine drip infusion to immobilize the patient. Ventilation was controlled by a Volume-preset ventilator. In the halothane group, the initial cuff pressure was 14.8 ± 1.3 (mean ± SE) cmH₂O but 10min after 0.15mg/kg of pancuronium injection, it increased to 21.7 ± 2.3cmH₂O (control). Ten min after inhalation of 0.75% of halothane, cuff pressure decreased to 14.7 ± 2.3cmH₂O (34 ± 11% decrease from the control value). In the enflurane group, the initial cuff pressure was 17.6 ± 1.8cmH₂O and it increased to 21.0 ± 1.7cmH₂O (control) 10min after pancuronium injection. Ten min after 1.7% of enflurane inhalation, cuff pressure decreased to 17.1 ± 2.3cmH₂O (23.9 ± 6% decrease from the control value). Halothane and enflurane produced similar tracheal dilatation in healthy individuals.(Yasuda I, Irimada M, Hirano T et al.: Tracheal dilatation by halothane and enflurane in man. J Anesth 2: 46–49, 1988)     

Papovavirus detection by electron microscopy in the brain of an elderly patient without overt progressive multifocal leukoencephalopathy

Virions resembling papovavirus were demonstrated in glial cells in the brain of an aged patient without overt progressive multifocal leukoencephalopathy. The patient was not in a severely immunocompromised state. On histological examination, only a few tiny incomplete necrotic foci were found in the subcortical area. These foci were widely dispersed. Rare, swollen oligodendroglial cells and astrocytes in which papovavirus capsid protein (VP-1) was demonstrated immunohistochemically were present around the foci. The two typical types of virus particles i.e. 35 to 40 nm round particles and elongated particles, were observed in the nuclei of the swollen glial cells. The latter were in the minority. Distinct crystals were also found in the nuclei. The centre-to-centre distance of the particles in the crystals, about 40 nm, and the electron-opaque spots of the round-shaped virions and of the elongated particles, were indicative of structural subunits of papovavirus capsids. This case provides further evidence that papovavirus, possibly JC virus, may be reactivated in the brains of aged patients who are not in an immunocompromised state.     

Stimulation of non-specific resistance by heterologous endotoxins and experimental immunity to Bordetella pertussis in mice

A single intraperitoneal administration of Bordetella pertussis vaccine produced within a few days an increased resistance in mice against intracerebral infection with B. pertussis strain 18–323 such as has previously been described by Evans and Perkins as early or interference immunity.

Intraperitoneal administration of the endotoxin of B. pertussis induced a relatively transient resistance against intracerebral infection with Salmonella typhi strain Ty2, but not against intracerebral infection with B. pertussis organisms.

When the treatment was made intracerebrally however, heterologous and homologous endotoxins as well as a synthetic double-stranded RNA complex of polyriboinosinic and polyribocytidylic acids (poly I.C) could increase the resistance of mice against intracerebral infection with B. pertussis organisms. In brains of animals thus treated, evident suppression of bacterial growth comparable to that in a passive immunity experiment was seen.

By the use of brain extract prepared from mice or rats treated intracerebrally with heterologous endotoxin, the non-specific resistance could be successfully induced in mice.

To substantiate any possible relation of such a non-specific resistance induced by endotoxins to the early immunity seen after the intraperitoneal injection of B. pertussis vaccine further efforts are necessary.
