[Mass screening for osteoporosis in Nansei--the Nansei Study (the second report)].

We performed screening for osteoporosis for the early detection of a decrease in the bone mineral density. The subjects consisted of 852 inhabitants (308 males and 544 females) aged 40 years or more in Nansei (population, 12, 107) in Mie Prefecture. Interviews, measurement of height and body weight, blood examination, and determination of the bone mineral density by the MD method were performed. In addition, a questionnaire on diet was carried out. The bone mineral density was decreased in 76 subjects (8.9%), of whom females were the majority. Height and body weight were significantly lower in the group with decreased bone mineral density than in the group with normal bone mineral density. The serum calcium (Ca), alkaline phosphatase (ALP), and inorganic phosphorus (P) levels were similar in the two groups. Concerning the family profile, the percentage of subjects living alone was significantly higher (p < 0.05) in the group with decreased bone mineral density (13.5%) than in the group with normal bone mineral density (3.6%). Screening for osteoporosis is still in the trial stage and involves various problems that require further studies. As subjects for screening, females before, during, and immediately after menopause are important.

Effectiveness of concomitant setiptiline maleate (Tecipul) on negative symptoms of schizophrenia.

1. Setiptiline maleate was administered to schizophrenic patients with the object of improving their negative symptoms. 2. Moderate improvements were observed in 58% of the treated patients, thus usefulness of this drug was demonstrated. 3. There was no aggravation of symptoms, and side effects were minor. 4. Measurements of plasma monoamine metabolites showed a tendency of MHPG to decrease and a significant decrease in 5-HIAA, but no change in the level of HVA was observed, suggesting a relationship between the negative symptoms and noradrenaline and/or serotonin systems.

[Hilar type squamous cell carcinoma confined within the bronchial wall with hilar lymph node metastasis: a case report].

A 60-year-old male patient visited our hospital for evaluation of positive sputum cytology. A chest X-ray film revealed no abnormal shadows. Bronchofiberscopy showed a protruding lesion at the spur between left B8 and B9. Histological findings indicated squamous cell carcinoma. Left lower lobectomy with hilar and mediastinal lymph node dissection was performed. The tumor did not infiltrate beyond the bronchial cartilage on postoperative histologic examination. However, hilar lymph node (#12 l) metastasis was identified. Surgical resection with lymph node dissection is mandatory even in the hilar type lung cancer confined within the bronchial wall.

Ectopic intrapulmonary thyroid.

An 83-year-old woman underwent resection of a pulmonary tumor. Histologic examination of the tumor demonstrated thyroid follicles without evidence of malignancy or teratomatous elements. Developmental anomaly may account for the ectopic intrapulmonary thyroid, which, to our knowledge, has not been reported in the literature.

A case of tardive Tourette-like syndrome.

We have had experience in treating tardive Tourette-like syndrome on a chronic schizophrenic patient. The patient was a 38-year-old woman. A diagnosis of schizophrenia was made in 1971 and she received repeated medications for 17 years. In 1989, she began to show vocal tic with coprolalia and motor tic. The medications were haloperidol 18 mg, zotepine 200 mg, levomepromazine 100 mg, biperiden 3 mg and nitrazepam 10 mg at the beginning of Tourette-like syndrome. We have tried to change the medications but this tardive Tourette-like syndrome continued to hang on. However, the symptoms gradually improved after a change in drugs; cessation of biperiden 3 mg and the administration of clonazepam 3 mg. The present case suggested that tardive Tourette-like syndrome might be a subtype of neuroleptic-associated tardive syndromes which might be treated with clonazepam.

Three cases of respiratory dyskinesia.

We present here three cases of respiratory dyskinesia (RD). RD was observed with a video recording and other recordings were made of a respiratory airflow with a thermistor, and abdominal movement with a strain gauge. Neurological findings and CT scanning indicated marked organic changes in the brain in these 3 cases. RD was complicated with tardive dyskinesia of the tongue and lips, and the symptoms were aggravated during stress and absent during sleeping, which are the characteristic features of extrapyramidal symptoms. The symptoms of the three cases have improved by decreasing the dose of butyrophenone derivatives and discontinuing anti-parkinsonian drugs, which suggested that an intracerebral imbalance of DA and ACh may be the cause of RD.

Parkinsonism manifesting depression as the first sign.

We have had experience in treating two patients with parkinsonism of which the first manifestation was depression. Case 1 was a 61-year-old woman. A diagnosis of depression had been made and repeated medication consisting mainly of antidepressants was given. However, the depressive state persisted and the signs of parkinsonism gradually became evident. The initial treatment with antidepressant drugs was replaced with one based on L-DOPA (400 mg a day). Subsequently, the symptoms of parkinsonism and depression diminished relatively rapidly. Case 2 was a 66-year-old man. His parkinsonism was suspected shortly after the onset, although the symptoms of depression were predominant. Similarly, the treatment based on L-DOPA (400 mg a day) relieved the symptoms of depression and parkinsonism rapidly. The present study described above indicates that parkinsonism should be suspected in cases of persistent depression and in patients who have depressive symptoms resistant to antidepressants, since parkinsonism may first manifest itself as depression.

Panic anxiety after abrupt discontinuation of mianserin.

We observed a case of withdrawal after abrupt discontinuation of mianserin. A 41-year-old woman was treated according to a diagnosis of depression, which was her 6th episode. Mianserin 30 mg/day, etizolam 1 mg/day and flunitrazepam 1 mg/day were administered. When the patient discontinued taking the drugs by herself because of subsiding of these symptoms, severe panic anxiety appeared. This panic anxiety was not relieved by taking etizolam and flunitrazepam again, but subsided rapidly by the re-administration of mianserin 30 mg/day, and because of that the depressive symptom also disappeared. From these experiences panic anxiety seemed to be a withdrawal symptom, and involvement of the noradrenergic system in panic anxiety as well as serotonergic system was suggested.

Nondominant temporal lobe epilepsy with depressive reaction.

A 56-year-old woman was admitted to our hospital because of insomnia and psychomotor retardation. This is her second admission. She was diagnosed as having depression and began to receive antidepressants. Her conditions got better after the treatment but the depressive state occurred again after she stopped taking those drugs. As EEG showed some spike discharges at the nondominant temporal lobe area, she was given anticonvulsants this time. Her depressive state improved rapidly by taking anticonvulsants instead of the antidepressants. The spike discharges at the nondominant temporal lobe area disappeared when the clinical symptoms improved.

[Clinical experience with cefmenoxime (CMX) in complicated urinary tract infections].

Cefmenoxime (CMX) was intravenously administered to 106 patients with complicated urinary tract infection at a daily dose of 2-4 g for 5 days. An excellent response in overall clinical efficacy was seen in 15 cases (18.3%), a moderate response in 46 cases (56.1%) and poor response in 21 cases (25.6%). Pyuria was cleared in 20 cases (24.4%), decreased in 22 cases (26.8%) and unchanged in 40 cases (48.8%). Bacteriuria was eliminated in 41 cases (50.0%), decreased in 17 cases (20.7%), relapsed in 7 cases (8.5%) and unchanged in 17 cases (20.7%). Bacteriologically, 74 (76.8%) of the 95 strains isolated were eradicated by CMX, and 22 (23.2%) persisted. Side effects were observed in 3 (abdominal pain, diarrhea and elevation of trans amylase) of the 106 cases. Judging from the above results, CMX is considered to be a useful drug in the treatment of complicated urinary tract infections.

Comparison of the effect of 3- and 5-day hypothermic perfusion of dog kidneys on metabolism of tissue slices.

Hypothermic perfusion effectively preserves the viability of kidneys for 3 days. Long-term preservation (5 days or greater) has not been consistently obtained. In this study, the differences between kidneys perfused for 3 and 5 days were compared by determining the "integrated-metabolic" capabilities of tissue slices incubated in vitro at 30 degrees C. The "integrated-metabolic" parameters determined include (1) respiration rates, (2) cell volume regulation [total tissue water (TTW) and saccharide permeable space], (3) rate of reaccumulation of K+ and pumping of Na+, (4) maintenance of ATP concentrations, and (5) mitochondrial functions. Conditions that result in high and low concentrations of ATP following perfusion of kidneys for 5 days were also compared for effects on tissue slice metabolism. The results indicate that energy metabolism in tissue slices is well preserved under all conditions and times of perfusion of kidneys. This includes average respiration rates (315 +/- 50, 275 +/- 35, and 255 +/- 45 mumol O2/hr/g dry wt at 0, 3, and 5 days, respectively, mitochondrial function [respiratory control ratio (RCR) = 4.6, 4.0, and 4.1 for 0, 3, and 5 days, respectively], and steady-state concentration of ATP in slices after incubation (4.0 +/- 1.45, 3.9 +/- 1.28, and 3.3 +/- 0.81 mumol/g/dry wt, for 0, 3, and 5 days, respectively). The primary differences between 3- and 5-day perfused kidneys were the capability of the slices to regulate cell volume and reaccumulate K+. Slices from kidneys perfused for 3 days maintained the TTW at 3.8 kg/kg dry wt, a value similar to that of control tissue slices. However, slices from 5-day perfused kidneys remained swollen (TTW = 4.6 kg/kg dry wt). Also, slices from the 5-day perfused kidney pumped K+ at less than one-half the rate found in slices from control or 3-day preserved kidneys. No significant differences were apparent in the permeability properties of the tissue slices from kidneys perfused for 3 and 5 days to radiolabeled saccharides. The defects in membrane-linked transport functions, resulting from long-term kidney perfusion, were reduced in kidneys containing a high concentration of ATP. The results suggest that one factor which may limit successful preservation of kidneys is the increased membrane permeability (to electrolytes) which is partially prevented by maintaining elevated concentrations of tissue ATP during perfusion.

[Studies on prophylaxis and therapy of pivmecillinam against post-prostatectomy urinary tract infection].

Patients received pivmecillinam (PMPC) after prophylactic use of various antimicrobial chemotherapeutic agents following prostatectomy, and their clinical responses were assessed for effectiveness in the treatment and prevention of postoperative infection. The data were also analyzed to explore the relationship between bacterial isolates obtained during the postoperative course and the antimicrobial agents administered prophylactically against postoperative infection. Therapeutic effect of PMPC: Treatment of postoperative infections with PMPC was effective in 36 (53.7%) out of 67 patients who had undergone prostatectomy. Prophylactic effect of PMPC: The use of PMPC provided effective prevention of infection in 22 (64.7%) out of 34 patients from whom no bacterial pathogen had been isolated before postoperative antimicrobial chemotherapy. Therapeutic responses to PMPC, compared between different types of operative procedure: There was little or no difference in therapeutic effectiveness of PMPC against postoperative infection when compared between two types of operative procedure, transurethral prostatectomy and subcapsular removal of the prostate. Incidence and types of bacterial isolates following prophylactic chemotherapy with various agents after prostatectomy: Possibly because cephapirin (CEPR) and ticarcillin (TIPC) were mainly administered, alone or in combination, for prophylaxis against postoperative infection, Serratia and Pseudomonas were most frequently isolated. The findings offer suggestions as to the appropriate combination of antimicrobial agents to be used for prophylactic purposes. Effectiveness of PMPC in the presence or absence of a preoperative indwelling urethral catheter: The use of PMPC was more effective both in the treatment and prevention of postoperative infection in cases without preoperative indwelling urethral catheterization than in those with it.

Captopril-associated granulocytopenia in hypertension after renal transplantation.

A living related kidney transplant recipient with normal renal functioning and hypertension secondary to renal artery stenosis was treated with captopril and developed reversible granulocytopenia. Complications caused by captopril, an angiotensin converting enzyme inhibitor, have been reported previously in hypertensive patients with systemic lupus erythematosus or with renal artery stenosis after renal transplantation. It is recommended that this drug be used with caution in this setting.

[Carcinoma of the urachus--report of 4 cases].

Four cases of urachal carcinoma are presented. The first case was a 36-year-old man who was admitted with the chief complaint of macrohematuria with mucinous debris. Cystoscopic examination revealed a single tumor at the dome of the bladder. Partial cystectomy and postoperative radiation therapy were performed. Histological findings showed a well differentiated adenocarcinoma. He has been well for twelve years postoperatively. The second case was a 52-year-old man who was admitted with the chief complaint of macrohematuria with mucinous debris. Cystoscopic examination revealed a single tumor at the dome of the bladder. Partial cystectomy and postoperative radiochemotherapy were performed. Histological findings showed a moderately differentiated adenocarcinoma. He died of a recurrent tumor 30 months after operation. The third case was 70-year-old man who was admitted with the chief complaint of macrohematuria with mucinous debris. Cystoscopic examination revealed multiple tumors at the dome of the bladder, internal urethral orifice and right lateral wall. Total cystectomy, ureterocutaneostomy and postoperative chemotherapy were performed. Histological findings showed a poorly differentiated adenocarcinoma. He died of a recurrent tumor 30 months after operation. The fourth case was a 68-year-old woman who was admitted with the chief complaint of macrohematuria with mucinous debris. Cystoscopic examination revealed a single tumor at the dome of the bladder. CT scan demonstrated a mass with calcification extending from the bladder dome superiorly. Partial cystectomy and postoperative chemotherapy were performed. Histological findings showed a well differentiated adenocarcinoma. She has been well for three months postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)
