A 19-year-old immunocompetent man was admitted to hospital with diplopia, nausea, vomiting and change in mental status. The patient had a history of tuberculous meningitis that was diagnosed at another hospital 6 months before the present admission, and at that time anti-tuberculosis treatment was initiated using a first-line drug combination. A computed tomography (CT) scan of the brain revealed non-communicating hydrocephalus. A ventriculo-peritoneal shunt was inserted surgically. Two months later, the patient was hospitalized again for fever, dysphagia and left hemiparesis. At that time, his cranial CT findings were within normal limits; however, magnetic resonance imaging (MRI) revealed an irregular multilocular peripheral contrast-enhancing lesion in the posterior fossa. The abscess was surgically drained. The presence of acid-fast bacilli in the abscess material was demonstrated by Ziehl-Neelsen staining. Mycobacterium tuberculosis grew on Lowenstein-Jensen culture medium, and the strain was found to be resistant to isoniazid. One month after the operation, the patient became quadriparetic. Cervical MRI revealed a cervico-thoracic syringomyelitic cavity, after which a syringoperitoneal shunt was placed. Treatment with four drugs was continued for 10 months, and then treatment with three drugs for a total period of 18 months. The patient recovered, with residual quadriparesis. Even though very rare, isoniazid-resistant M. tuberculosis may be the causative agent of progressive tuberculosis. 相似文献

AbstractWe read Cosansu’s commentary entitled “Effectiveness of the new inflammatory parameters in patients with chronic spontaneous urticarial” to our study with great interest. The author remarked that a limited number of patients had C-reactive protein levels and it was not specified whether there were any other drugs used by the patients and no information was given about the severity of the disease in our study. 相似文献

Background
Multifocal breast cancers (MFBCs) present a challenge to surgeons. Although its feasibility is still controversial, breast-conserving surgery (BCS) is not contraindicated for MFBCs. The investigators retrospectively evaluated the feasibility of BCS and reviewed histopathologic findings in patients with MFBC.Methods
A total of 222 patients with MFBC who were treated with either BCS (119 patients) or mastectomy (103 patients) at a single institution between January 2002 and December 2011 were retrospectively evaluated.Results
The median follow-up time was 55 months (range, 10 to 102 months). Lymphovascular invasion and lymph node involvement were significantly less frequent in the BCS group (48.8% vs 62.2% for lymphovascular invasion, P = .04; 52.1% vs 71.8% for lymph node involvement, P = .002). There were no differences in local recurrence rates between the 2 groups. The overall survival rates were 92% in the BCS group and 72% in the mastectomy group (P = .000).Conclusions
BCS is a feasible and safe procedure for the removal of multifocal tumors. Extended lymphovascular invasion is associated with mortality in patients who undergo mastectomy. 相似文献8.

Rocuronium is a non-depolarizing neuromuscular blocking agent which is associated with injection pain and induces withdrawal movement of the injected hand or arm or generalized movements of the body after intravenous injection. The aim of this randomized study was to compare the efficacy of pretreatment with oral dexketoprofen trometamol (Arvelles®; Group A) with placebo (Group P) without tourniquet to prevent the withdrawal response caused by rocuronium injection. The study cohort comprised 150 American Society of Anaesthesiologists class I–III patients aged 18–75 years who were scheduled to undergo elective surgery with general anesthesia. The patients response to rocuronium was graded using a 4-point scale [0 = no response; 1 = movement/withdrawal at the wrist only, 2 = movement/withdrawal involving the arm only (elbow/shoulder); 3 = generalized response]. The overall incidence of withdrawal movement after rocuronium injection was significantly lower in Group A (30.1 %) than in Group P (64.6 %) (p < 0.001). The incidence of score 0 withdrawal movements was higher in Group A (69.9 %) than in Group P (35.4 %), that of score 1 withdrawal movements was similar between groups (Group A 21.9 %; Group B 26.1 %) (p = 0.560) and that of score 2 withdrawal movements was lower in Group A (8.2 %) than in Group P (38.5 %) (p < 0.001). There were no score 3 withdrawal movements in either group (p > 0.05). These results demonstrate that the preemptive administration of dexketoprofen trometamol can attenuate the degree of withdrawal movements caused by the pain of the rocuronium injection. 相似文献

Objective. PTSD and major depression occur frequently following traumatic exposure, both as separate disorders and concurrently. Although much of Turkey is under threat of severe earthquakes, risk factors for developing psychiatric disorders among Turkish children have not yet been studied. The aim of the study was to examine risk factors for PTSD and depression develpoment in children. Method. A total of 160 survivors (102 girls and 58 boys) severely impacted by Turkey's 7.4-magnitude quake participated in a psychiatric interview 6–20 weeks after the disaster. The mean age was 14.43. Logistic regression was used to test effects of pre-disaster, disaster-related and post-disaster factors on diagnoses, yielding odds ratios (OR). Results. CAPS indicated that 96 (60%) had PTSD, and psychiatric interview found 49 (31%) with depression. Children diagnosed with PTSD were more likely to have witnessed death (OR=2.47) and experienced an extreme parental reaction (OR=3.45). Children with depression were more likely to be male (OR=4.48), have a higher trait anxiety score (OR=1.12 for every additional point), sustain injury (OR=4.29), and have lost a family member in the quake (OR=10.96). Focusing on the 96 children with PTSD, those with comorbid depression were more likely male, have a higher trait anxiety score, and have lost of family member. Conclusions. Mental health professionals should offer support to children witnessing death or losing a family member in a disaster. The ability of the family to remain calm and reassuring also may be a key factor in preventing PTSD. 相似文献
