Clinical application of a lung sound analysis in infants with respiratory syncytial virus acute bronchiolitis.

BACKGROUND: Objective investigation of the characteristics of acute bronchiolitis in infants is important for its diagnosis and treatment. METHODS: Lung sound data of 50 patients diagnosed with respiratory syncytial virus (RSV) acute bronchiolitis (m:f = 29:21, median of age 7 months), 20 patients with RSV acute respiratory tract infections without acute bronchiolitis (m:f = 10:10, 5 months) and 38 age-matched control infants (m:f = 23:15, 8 months) were analyzed using a conventional method and compared. Furthermore, the relationships between lung sound parameters and clinical symptoms (clinical score, length of hospital stay and SpO2 level) in the bronchiolitis and the non-bronchiolitis patients were examined. RESULTS: Results of lung sound analysis showed that the inspiratory sound power of patients with RSV respiratory tract infections was low and the expiratory sound power was high compared with those of the controls. When the patients with RSV respiratory tract infections were divided into the bronchiolitis and non-bronchiolitis groups, the expiratory/inspiratory ratio of the bronchiolitis patients was greater than that of the non-bronchiolitis patients. There was no difference in the clinical symptoms, clinical score and length of hospital stay between the bronchiolitis and non-bronchiolitis patients, except for the SpO2 level on admission. CONCLUSION: Lung sound analysis confirmed that patients with RSV acute bronchiolitis present with marked airway narrowing. Considering these results as a characteristic of acute bronchiolitis, it would be meaningful to reflect it in the improvement of diagnosis, treatment and subsequent management.

Successful Emergency Decompressive Laminectomy for Burkitt Lymphoma with Metastatic Spinal Lesions: A Case Report.

Although Burkitt lymphoma (BL) usually arises in the abdomen or pelvis, it can also arise in the epidural space as a primary or secondary site and present with back pain or limb weakness. Emergency management is necessary to relieve spinal cord compression (SCC). Herein, we report a case of BL with metastatic spinal lesions in a 16-year-old female who presented with sudden-onset progressive walking difficulty. She was admitted to a previous hospital where she presented with abdominal pain and vomiting and was diagnosed with intussusception via a computed tomography scan. Laparoscopic small bowel resection was performed, during which a diagnosis of BL was made on the basis of pathological examination. Sudden numbness in the extremities and the complete inability to walk occurred ten days after surgery. Thoracolumbar MRI revealed a metastatic mass extending from C7 to T6 with evidence of SCC. Emergency decompressive laminectomies (from C7 to T6) and partial debulking of the tumor were performed 12 hours after the onset of her neurologic symptoms. She was subsequently treated with chemotherapy, and she made a complete neurologic recovery. Emergency decompressive laminectomies for BL with spinal lesions could effectively lead to the recovery of neurologic symptoms.

Effect of wheeze and lung function on lung sound parameters in children with asthma.

BACKGROUND: In children with asthma, there are many cases in which wheeze is confirmed by auscultation with a normal lung function, or in which the lung function is decreased without wheeze. Using an objective lung sound analysis, we examined the effect of wheeze and the lung function on lung sound parameters in children with asthma. METHODS: A total of 114 children with asthma (males to females = 80: 34, median age 10 years old) were analyzed for their lung sound parameters using conventional methods, and wheeze and the lung function were checked. The effects of wheeze and the lung function on lung sound parameters were examined. RESULTS: The patients with wheeze or decreased forced expiratory flow and volume in 1 s (FEV1) (% pred) showed a significantly higher sound power of respiration and expiration-to-inspiration sound power ratio (E/I) than those without wheeze and a normal FEV1 (% pred). There was no marked difference in the sound power of respiration or E/I between the patients without wheeze and a decreased FEV1 (% pred) and the patients with wheeze and a normal FEV1 (% pred). CONCLUSIONS: Our data suggest that bronchial constriction in the asthmatic children with wheeze similarly exists in the asthmatic children with a decreased lung function. A lung sound analysis is likely to enable an accurate understanding of airway conditions.

Exploratory study of pre-surgical medications with dienogest or leuprorelin in laparoscopic cystectomy of endometrial cysts.

AIM: The aim of this study was to compare the effects of pre-surgical medication with dienogest or leuprorelin on post-surgical ovarian function. MATERIAL AND METHODS: We conducted an exploratory study in two centers in Japan that comprised 30 patients with ovarian endometrial cysts for whom surgical excision was planned. Patients were enrolled and divided into pre-surgical medication groups with dienogest or leuprorelin for 12 weeks. Thereafter, patients were treated by laparoscopic cystectomy. The primary outcome was ovarian function post-surgery, as assessed by serum anti-Müllerian hormone (AMH) level, antral follicle count (AFC) and resumption of menses. Secondary outcome was the effect of pre-surgical medication, as assessed by the size of endometrial cysts and visual analog scale (VAS) score. Serum AMH, AFC, size of endometrial cysts, and VAS scores were measured at baseline (before medication), after medication (1 day before surgery), and at 4 and 12 weeks post-surgery. RESULTS: Serum AMH levels did not change after pre-surgical medication with either dienogest or leuprorelin. Although AMH decreased after surgery, it recovered by 12 weeks post-surgery in both groups with no statistically significant difference. Mean AFC did not change after surgery in either group. Menses returned by 12 weeks post-surgery in all patients except for those who were pregnant. The rate of reduction of endometrial cyst volume did not differ between the groups. Both dienogest and leuprorelin were associated with substantial reductions in VAS scores. CONCLUSION: There were no statistically significant differences between pre-surgical medication with dienogest and leuprorelin in post-surgical ovarian function. Both medications were effective in reducing endometrial cyst volume and VAS score.

Yokukansan improves distress of medical staff, and cognitive function and motivation in patients with destructive and aggressive behaviors after traumatic brain injury.

AIM: Yokukansan (a Japanese Kampo medicine) has been reported to be safe and useful in treating behavioral and psychological symptoms in dementia patients. This study aimed to investigate the effects of yokukansan on destructive and aggressive behaviors in patients after traumatic brain injury. METHODS: From April 2008 to July 2010, 189 patients who suffered traumatic brain injury were admitted to our tertiary emergency center. Of these, patients with destructive and aggressive behaviors were treated with neuroleptics. Seven patients (five men and two women) who could not be controlled by neuroleptics were given yokukansan (2.5 g powder) three times a day before meals. Main underlying conditions included brain contusion in three patients, acute subdural hematoma in two, and acute epidural hematoma in two. The following assessments were carried out at baseline and 1 and 2 weeks after initiation of treatment: the Glasgow Coma Scale for the assessment of disturbed consciousness after traumatic brain injury; Neuropsychiatric Inventory for the distress of medical staff; Mini-Mental State Examination for cognitive function; Barthel Index for activities of daily living; Vitality Index for motivation; presence of adverse effects and drug interactions. RESULTS: After treatment with yokukansan, patients showed significant improvements in Glasgow Coma Scale (P = 0.001), Neuropsychiatric Inventory (P = 0.016), Mini-Mental State Examination (P = 0.029), Barthel Index (P = 0.043), and Vitality Index (P = 0.013). No adverse effects or drug interactions between yokukansan and Western medicines were observed. CONCLUSION: Yokukansan improved the Glasgow Coma Scale, Neuropsychiatric Inventory, Mini-Mental State Examination, Barthel Index, and Vitality Index without any adverse effects or drug interactions with Western medicines in patients with destructive and aggressive behaviors after traumatic brain injury.

Cervical large cell neuroendocrine carcinoma with cytologic presentation: a case report.

BACKGROUND: Large cell neuroendocrine carcinoma (LCNEC) is a rare and aggressive cervical neoplasm. Few cytologic or colposcopic findings of LCNEC have been reported. CASE: A 37-year-old woman, gravida 6, para 4, presented with vaginal bleeding for 3 months. The cervical smears showed cells dispersed as single cells or arranged as loosely cohesive sheets or glandlike aggregate and the nuclear size was almost 3-5 times larger than that of small lymphocytes. The cytologic, pathologic and immunohistochemical examinations suggested LCNEC. The patient underwent a radical hysterectomy and then received radiation and systemic chemotherapy. CONCLUSION: Cytologic and colposcopic findings for LCNEC of the uterine cervix are reported. Patients with LCNEC have poor prognoses. Early diagnosis of the tumor is important.
