[A case of multiple extracranial vertebral artery aneurysms associated with neurofibromatosis].
An unusual case of multiple aneurysms of the extracranial vertebral artery associated with neurofibromatosis is presented. A 48-year-old woman, complaining of weakness and numbness of the left upper extremity, was admitted to our hospital on July 27, 1987. She had undergone the removal of a left internal thoracic artery aneurysm due to hemothorax on June 12, 1987. On the next day, the symptoms of the left upper extremity appeared. On admission, general physical examination showed multiple cafe-au-lait spots on her body and cervicothoracic scoliosis. Neurological examination revealed left C5, 6 radiculopathy. Cervical CT scans showed enhanced masses at the transverse foramina. Left subclavian angiography demonstrated multiple extracranial vertebral artery aneurysms from the origin of the vertebral artery to the C4 level. This case was treated by proximal and distal ligation of the aneurysms. Postoperative right and left angiograms revealed no aneurysms filled with contrast materials. The weakness and numbness of the left upper extremity disappeared gradually after the operation.

[Primary biliary cirrhosis: symptoms, laboratory data and diagnosis].
The most frequent and important symptoms in primary biliary cirrhosis (PBC) are pruritus and jaundice. In the majority, jaundice appears within one half to two years of onset of pruritus. Xanthoma, bone change and sicca syndrome are often observed. The recent increase in number of asymptomatic PBC is the result of progagation of medical examination. In the biochemical tests, elevation of the biliary enzymes, such as ALP and gamma-GTP, is characteristic, as well as, a high level of serum IgM. Serum bilirubin values are gradually raised along with the clinical course of the disease. Positive antimitochondrial antibody (AMA) is the most valuable immunological finding for the diagnosis of PBC. Anti-pyruvate dehydrogenase complex E2 component E2 has the same significance as AMA. Diagnostic criteria si shown in this paper.

[A case of pulmonary lymphangiomyomatosis diagnosed by biopsy of retroperitoneal tumor and treated with hormonal therapy].
A 34-year-old woman was admitted to our hospital because of exertional dyspnea and ascites. Chest roentgenogram showed hyperinflation of the lung and diffuse reticular shadows. Abdominal CT showed retroperitoneal tumors. Ascites was considered to be chylous. These findings strongly suggested the diagnosis of pulmonary lymphangiomyomatosis. Under lumbar anesthesia, laparotomy was performed, and the histological finding of the retroperitoneal tumor revealed angiomyoma. Bilateral oophorectomy was performed. Medroxyprogesterone at 15 mg/day was administered postoperatively. In advanced cases of this disease, open lung biopsy or even transbronchial lung biopsy is often avoided because of severe cardiopulmonary dysfunction. However, such cases associated with retroperitoneal tumor, laparotomy is quite useful not only in making the diagnosis but also in the treatment of this disease.

Molecular cloning, expression, and gene localization of a fourth melanocortin receptor.
The recent cloning of three melanocortin receptors suggests an unexpected diversity in this family of seven transmembrane G-protein linked receptors. Herein, we report the cloning, expression, and gene localization of a fourth human melanocortin receptor, the melanocortin-4 receptor. By Northern blot analysis and in situ hybridization, this receptor is expressed primarily in the brain, but its expression is notably absent in the adrenal cortex, melanocytes, and placenta. Agonist stimulation of COS-1 cells transiently transfected and L-cells permanently transfected with the coding region of the cloned melanocortin-4 receptor leads to increases in intracellular cyclic 3',5'-adenosine monophosphate. The profile of the responses of the melanocortin-4 receptor to different melanocortins distinguishes it from melanocortin receptors previously described. Using the technique of fluorescent in situ hybridization, the gene encoding the melanocortin-4 receptor was localized to chromosome 18 (q21.3).

Molecular cloning of a novel melanocortin receptor.
Using the technique of the polymerase chain reaction primed with oligonucleotides based on the homologous transmembrane regions of seven transmembrane G protein-linked receptors, we isolated three full-length human genes that encode a novel subgroup of this receptor family. Recently, two of these receptors were identified as specific for alpha-melanocyte-stimulating hormone (alpha-MSH) and adrenocorticotropic hormone. We report the molecular cloning and pharmacologic characterization of a third member of this subgroup. The gene for this receptor encodes a protein of 361 amino acids in length. Its pharmacology characterizes it as an MSH receptor specific to the heptapeptide core common to adrenocorticotropic hormone and alpha-, beta-, and gamma-MSH. By Northern blot hybridization and polymerase chain reaction, it is expressed in brain, placental, and gut tissues but not in melanoma cells or in the adrenal gland. These findings may yield insight into the physiology of peptides derived from pro-opiomelanocortin post-translational processing.

Maxillofacial fractures in children.
A clinico-statistical and long-term follow-up study was performed on 81 pediatric fractures seen during the 14 years between 1977 and 1990. Of all maxillofacial fractures, the incidence of pediatric fractures was 14.7%. The ratio of boys to girls was 2.1:1, and the highest incidence involved boys over 13 years of age. Fractures of the upper alveolar bone and mandible were common. Conservative therapy, such as maxillomandibular fixation using orthodontic brackets was usually performed and was found to be successful. The long-term follow-up study revealed that 5 out of 21 patients with alveolar fractures complained of malocclusion and it is suggested that a longer duration of intramaxillary fixation and long-term follow-up might be needed for alveolar fractures in children.

[A case of cytomegalovirus pneumonia and Pneumocystis carinii pneumonia with lung cancer--diagnosis by the polymerase chain reaction].
A 64-year-old male was admitted to Oita Medical University Hospital because of primary lung cancer. After the anticancer chemotherapy, the patient developed a high fever. His chest X-ray showed diffuse reticular shadows bilaterally, which were considered to be a drug induced pneumonia, then pulse therapy with corticosteroid was performed. With this treatment, the diffuse reticular shadows disappeared. One month later, however, a severe interstitial pneumonia developed, and the patient died of respiratory failure. Autopsy findings demonstrated cytomegalovirus (CMV) and Pneumocystis carinni pneumonia. The polymerase chain reaction (PCR) for CMV in mononuclear cells in the blood was positive through out his hospitalization. In the sera, however, it was negative at the time of admission, then became positive 10 days before the onset of pneumonia. In addition, the PCR for P. carinni on the swab became positive as well. These results imply that PCR can be used for diagnosis of CMV and P. carinii infections from sera or swabs.

[An adult patient with EDTA-dependent pseudothrombocytopenia due to rubella virus infection].
We experienced an adult patient with EDTA-dependent pseudothrombocytopenia due to rubella virus infection. A 23-year-old male complaining of eruption and fever was admitted to our hospital on June 21, 1992. Laboratory findings on admission showed the platelet count 1.5 x 10(4)/microliters with EDTA, but 11.5 x 10(4)/microliters with heparin. Platelet agglutination was absorbed in the peripheral blood smear samples with EDTA. The hemagglutination inhibition titer for rubella virus raised from 1:32 to 1:52 in paired sera. We diagnosed this patient as having EDTA-dependent pseudothrombocytopenia and mild true thrombocytopenia due to rubella virus infection.

[Disseminated Trichosporon beigelii infection: report of nine cases and review].
Trichosporon beigelii (formerly called Trichosporon cutaneum) is an emerging pathogen of disseminated trichosporonosis in immunocompromised patients. We conducted postmortem microbiological examinations of lung aspirates and blood in the heart. T. beigelii was isolated from the samples of 7 (2.24%) of 313 patients. Five of 7 patients isolated were diagnosed as having trichosporonosis based on histochemical and clinical findings. The other two were considered as colonization. Immunohistochemical study using Cryptococcus neoformans-absorbed antiserum to T. beigelii was carried out on the sections of autopsied tissues with deep mycoses. The sections from seven patients were positively stained, which were formerly diagnosed as candidiasis and/or aspergillosis. Consequently, 9 patients had disseminated trichosporonosis caused by T. beigelii. In Japan, 43 patients including the present 9, 31 males and 12 females, aged 51 (range, 2-84), were reported in the literature. Thirty-seven (86%) patients had hematologic malignancy, and the majority of them revealed profound neutropenia due to cytotoxic chemotherapy. Thirty-eight (88%) patients died despite the anti-fungal chemotherapy including amphotericin B. New strategies for refractory disseminated trichosporonosis in immunocompromised patients is needed.

Primary intracranial germinoma involving the medulla oblongata--case report.
A 30-year-old female presented with intracranial germinoma involving both the medulla oblongata and suprasellar region. Such involvement of medulla oblongata with initial clinical symptoms similar to brainstem glioma has not been previously reported. Combination chemotherapy using cisplatin and etoposide achieved disappearance of the suprasellar tumor, and decreased size of the medulla oblongata tumor. Relapse occurred 6 months after first treatment, when combination chemotherapy with etoposide and carboplatin achieved reduction in tumor size again.

Reinforced cytotoxicity of lymphokine-activated killer cells toward glioma cells by transfection with the tumor necrosis factor-alpha gene.
Lymphokine-activated killer (LAK) cells generated from peripheral blood lymphocytes incubated with recombinant interleukin-2 were transfected with the human tumor necrosis factor (TNF)-alpha gene by means of novel liposomes with a positive change on their surface. The cells secreted significant amounts of TNF-alpha into the culture medium and exhibited reinforcement of cytotoxicity toward a human glioma cell line (U251-SP), being three times more cytotoxic than nontransfected LAK cells. The mechanism for the reinforcement of cytotoxicity is considered to involve not only an increase in TNF-alpha secretion from LAK cells but also its expression on their surface. Intratumoral or intrathecal injection of LAK cells transfected with the TNF-alpha gene may be useful for the treatment of patients with malignant gliomas.

Sequential internal mammary artery grafts: clinical and angiographic assessment.
Between January 1988 and August 1992, the internal mammary artery was used as a sequential graft to the left anterior descending artery and/or diagonal branch in 34 patients. One patient died in hospital. After surgery all survivors were free from angina for a follow-up of up to 4 years. Recatheterization was performed in 33 patients within 1 year of surgery. Postoperative angiography showed that 65 anastomoses (98%) were patent, but three patent grafts (5%) between the proximal and distal sequential anastomoses showed 'string sign'. It is important to prevent 'string sign' in sequential grafting. It is considered that sequential internal mammary artery grafting should be limited to coronary arteries with severe stenosis that divides anastomosed coronary arteries into two.

Thallium-201 myocardial SPECT in Bland-White-Garland syndrome: two adult patients with inferoposterior perfusion defect.
A myocardial 201TI SPECT examination was conducted both prior to and following surgery of two adult patients with an anomalous left coronary artery originating from the pulmonary artery (Bland-White-Garland syndrome). In this syndrome, the anterior wall is usually affected first. Preoperative examination demonstrated an inferoposterior perfusion defect. In both patients, the right coronary artery was markedly dilated, and a significant left-to-right shunt formation was observed. Both patients were diagnosed as possibly having coronary steal syndrome. A prolonged inadequate blood supply to the right coronary region may cause inferoposterior cardiomyopathy. In the postoperative examination, myocardial perfusion markedly improved in one patient whose preoperative SPECT showed redistribution in a delayed scan. Thallium-201 SPECT was therefore found to be useful in assessing both the preoperative and postoperative myocardial perfusion.

[Adult respiratory distress syndrome due to sepsis caused by Staphylococcus aureus: a case report].
A 59-year-old man, under treatment for osteoarthritis of the right hip joint, was admitted to the Department of Orthopedic Surgery of Health Insurance Nankai Hospital with complaints of high fever and severe right hip joint pain. Since he developed shock, he was transferred to the Department of Internal Medicine. The laboratory data showed marked increase of acute phase reactants, and Staphylococcus aureus was cultured from the abscess in the right hip joint. The chest X-ray film the next day showed diffuse pulmonary edema of both lungs. The diagnosis of adult respiratory distress syndrome (ARDS) due to sepsis caused by S. aureus was made. Septic ARDS due to S. aureus is rare. The patient was cured by mechanical ventilation and administration of antibiotics, methyl-prednisolone and Urinastatin, along with drainage of the abscess in the right hip joint.

A case report of allergic granulomatosis and angiitis (Churg-Strauss syndrome) with a review of the literature.
We report the case of a 67-year-old man with allergic granulomatosis and angiitis (AGA; Churg-Strauss syndrome) who developed nephrotic syndrome during his clinical course and demonstrated membranous nephropathy on renal necropsy by electron microscopy. Following the development of symptoms of bronchial asthma accompanied by eosinophilia and mononeuritis multiplex, transbronchial lung biopsy confirmed a diagnosis of AGA. The patient died of pneumonia and disseminated intravascular coagulopathy, but necropsy revealed severe tubulo-interstitial damage with neutrophilic infiltration and, in half of the glomeruli, mesangial proliferation with subepithelial dense deposits. This paper thus describes a rare case of AGA complicated by a secondary type of stage I membranous nephropathy.
