Granulomatous balanoposthitis after intravesical Bacillus-Calmette-Guerin instillation therapy

We report a rare case of granulomatous balanoposthitis after intravesical Bacillus-Calmette-Guerin (BCG) instillation therapy in a 58-year-old man, which followed transurethral resection (TUR) for recurrent bladder cancer, when his anterior urethra was slightly narrow and his foreskin was with phimosis. Intravesical BCG instillation therapy was started for prophylaxis of recurrent bladder cancer after TUR. Multiple painless firm papules on glans penis, edema in the foreskin and low-grade fever appeared after the seventh instillation, for which the single antituberculous agent isoniazid (300 mg/day) was administered. Biopsy of the papules on glans penis and foreskin revealed granulomatous balanoposthitis. Low-grade fever normalized and the papules disappeared within 1 week. The patient continued chemotherapy with isoniazid for the next 12 months. There was no recurrence of bladder cancer or balanoposthitis for 15 months and to date.     

Immunohistochemical localization of cathepsin D, proliferating cell nuclear antigen and epidermal growth factor receptor in human breast carcinoma analysed by computer image analyser: correlation with histological grade and metastatic behaviour

 

Aims:

The purpose of this study is to examine the relationship between immunohistochemical localization of cathepsin D (CD), proliferating cell nuclear antigen (PCNA) and epidermal growth factor receptor (EGF-R) in 65 cases of breast carcinoma in Japanese women and traditional prognostic factors such as histological grade, lymph node status, mitotic rate and clinical stage, in order to possibly identify some indicator(s) that may be specifically associated with prognosis.  

Methods and results:

Serial sections of 5-μm thick were cut from the archival formalin-fixed, paraffin-embedded tissue blocks, and processed for CD, PCNA and EGF-R immunostaining. The results were analysed by computer-based image analysis system. All samples showed a positive immunoreaction for cathepsin D in both the parenchyma and stroma. However, the staining area and intensity varied from cell to cell in the parenchyma and stroma as well as among samples. Subsequently, the evaluation of immunostaining for CD was separately performed in both the parenchyma and stroma (CDpar and CDstr, respectively) and the combination of both components (CDtotal). PCNA and EGF-R showed positive immunostaining almost exclusively in the parenchymal component of the carcinoma tissue specimens. CDtotal significantly correlated with the histological grade, PCNA index (PI), mitotic rate (MR), EGF-R and lymph node metastasis. Significant correlation was also demonstrated between CDpar and the histological grade, EGF-R and lymph node metastasis, or between CDstr and MR, EGF-R and lymph node metastasis. EGF-R correlated highly with the histological grade, MR score, lymph node metastases and recurrence-free survival.  

Conclusions:

Both the CD parameters and EGF-R are valuable indicators for predicting the biological behaviour of human breast carcinoma.     

Quality of ulcer healing influences the relapse of gastric ulcers in humans

The usefulness of dye-contrast endoscopy for the evaluation of the quality of gastric ulcer healing and the prediction of relapse was investigated. Sixty consenting patients whose ulcers healed during 3 months of treatment underwent endoscopy for the identification of the pattern of mucosal regeneration. Patients were monitored for relapses for up to 18 months after antiulcer therapy had ended. The pattern of regeneration was flat in 24 patients, nodular in 25 and intermediate in 11. Internal hypoechoic areas seen by endoscopic ultrasonography were less common and histological maturity was better in the patient group with the flat pattern compared with the patient group with the nodular pattern of mucosal regeneration. Prostaglandin E, synthesis was highest in the group with the flat pattern of mucosal regeneration and the relapse rate was lowest in this group. We conclude that the evaluation of the quality of ulcer healing is possible and that findings in individuals may aid the prediction of relapse for particular patients.     

Phase II Study of Mitoxantrone in Patients With Non-Small Cell Lung Cancer

A phase II study of mitoxantrone was performed in 24 patientswith non-small cell lung cancer (NSCLC). Mitoxantrone was administeredby intravenous drip infusion of 12 mg/m² every three weeks.There were no responders among the 21 evaluable patients includingfive patients without prior therapy. The major hematologicaltoxic effect was leukocytopenia. Thrombocytopenia and decreasein hemoglobin were slight. A change in the electrocardiogramwas observed in one patient and one patient experienced cardiogenicshock. Mitoxantrone is not acceptable for the treatment of NSCLC becauseof its low antitumor activity, and careful observation is neededfor administration of this agent to patients with pre-existingrisk factors, such as prior anthracycline exposure, mediastinalradiation or underlying cardiovascular disease.     

Neuropsychological test for the detection of dementia in elderly individuals: the Nishimura Dementia Test

Background: Progression of the core and accessory symptoms of dementia can be slowed if drug therapies and psychosocial interventions are administered at an early stage. The aim of this study was to develop and standardize a neuropsychological test for the elderly that can detect dementia at an early stage with high sensitivity and can evaluate a wide range of severities of dementia based on assessments of various cognitive functions. Methods: A preliminary test consisting of 23 items and the Nishimura Mental State Scale for the Elderly (NM Scale), which evaluates the mental functions of elderly individuals by observing their actual behaviors in daily life, were administered to 448 elderly subjects. After applying Hayashi’s quantification theory type I to the results, we revised the preliminary test to construct a neuropsychological test for the elderly, which we named the Nishimura Dementia Test (ND Test), and standardized it. Then, we examined its validity and test–retest reliability. Results: Among the 448 subjects, there was a strong correlation between the ND Test scores and NM Scale scores. The ND Test showed a good general agreement rate for the discrimination of the severity of dementia, and good sensitivity and specificity of discrimination of dementia when compared with the actual NM Scale. Using different groups of elderly subjects, the ND Test showed validity and test–retest reliability, and the ND Test scores showed strong correlations with the Revised Hasegawa Dementia Scale scores and the Mini‐Mental State Examination scores. Conclusions: The ND Test is based on assessment of a variety of cognitive functions and can evaluate a wide range of severities of dementia with good validity and reliability.     

Expulsion of Hymenolepis nana from mice with congenital deficiencies of IgE production or of mast cell development

The roles of IgE and mast cells on expulsion of adult Hymenolepis nana from the intestine were examined in mice. IgE-dependency was determined by comparing congenitally IgE-deficient SJA/9 and IgE-producing SJL/J mice infected with 50 H. nana eggs. Anti-H. nana IgE antibody was detected at three weeks post infection (p.i.) in SJL but not in SJA mice. The number of adult worms in the intestines of SJA and of SJL mice were similar at two weeks, but significantly more were found in SJA mice at three weeks p.i. Treatment of mice with anti-ɛ antibody also resulted in an increased worm burden at three weeks, suggesting participation of IgE in expulsion of H. nana. Intestinal mastocytosis was induced by infection regardless of the IgE status of the mice. Mast cell-dependency was tested in mast cell-deficient W/W^u and in normal littermate +/+ mice infected with 100 H. nana eggs. Anti-H. nana antibody was detected in both groups of mice at three weeks p.i. Worm expulsion seemed to be mast cell dependent because expulsion was less complete in W/W^u mice at three weeks p.i. Peripheral blood eosinophilia was comparable at three weeks p.i. in both IgE and mast cell sufficient and deficient mice. These results suggest that IgE and mast cells participate in the expulsion of H. nana adults from intestine in mice.     

A mild case of nesidioblastosis with diagnostic and therapeutic difficulty

A female infant with nesidioblastosis who showed mild clinical symptoms is reported. In this patient, insulin levels and insulin to glucose ratios (IRI/G) were often normal. Regular milk feedings supplemented with continuous glucose infusion (0.7-2 mg/kg per min) or oral glucose feedings (4.5 mg/kg per min) prevented hypoglycemia. As leucine-sensitivity was diagnosed at 2 months of age, she was started on diazoxide. This was, however, ineffective, and adverse effects appeared. Subtotal pancreatectomy (95%) was therefore attempted at 5 months of age, and persistent normoglycemia as well as normal growth and development followed up to 3 years after the operation. The pancreas showed characteristic signs of nesidioblastosis. The above clinical observation suggests that a patient with nesidioblastosis whose blood glucose level is easily controllable may develop an unexpected episode of hypoglycemia in the presence of a leucine sensitivity. In such a patient, diazoxide or, when it is of no avail, surgical intervention should promptly be instituted to prevent possible neurologic sequelae induced by hypoglycemia.     

Selective Electrothermolysis of the Sebaceous Glands: Treatment of Facial Seborrhea

BACKGROUND: There are few publications on facial seborrhea treatment. A focused therapy is needed. OBJECTIVE: Our aim was to evaluate the efficacy of electrothermolysis of the sebaceous glands. METHODS: In the preliminary studies, histologic changes in the cheek skin by electrothermolysis were examined by light microscopy. In the clinical studies, 15 adult women subjects with facial seborrhea were treated four times by the same procedure. A 1.50-mm-long needle with a 0.45-mm base insulation was inserted into pores in the forehead and cheeks, and a high-frequency electrical current was applied for 0.25 to 0.50 seconds with an output of 40 W. Each treatment took 60 to 90 minutes. The subjects returned for 6-months follow-up after their fourth treatment. RESULTS: Histology 1 and 6 months later showed fewer sebaceous glands and the development of fibrosis. All 12 subjects who completed the 6-month follow-up gave a subjective assessment of continuous reduction of facial seborrhea. On a scale of 0.0 to 3.0, the mean improvement score was 1.67+/-0.75. The mean reduction rate of skin surface lipids was 31.5% by sebumeter (p< .01). CONCLUSIONS: Even though this is a pilot, uncontrolled clinical assessment study, electrothermolysis of sebaceous glands may be an effective and safe approach for facial seborrhea treatment.
