Chemical composition and cytotoxic activity of the leaf essential oil of <Emphasis Type="Italic">Eugenia zuchowskiae</Emphasis> from Monteverde,Costa Rica

The leaf essential oil of Eugenia zuchowskiae from Monteverde, Costa Rica, has been obtained by hydrodistillation and analyzed by GC–MS. The principal constituents of E. zuchowskiae leaf oil were α-pinene (28.3%), β-caryophyllene (13.2%), α-humulene (13.1%), and α-copaene (8.1%). The leaf essential oil of E. zuchowskiae showed pronounced in-vitro cytotoxic activity against MCF-7, MDA-MB-468, and UACC-257 human tumor cell lines. The major components showed cytotoxic activities comparable to doxorubicin (LC₅₀ 14–70 μg/ml).     

Tubal patency and fertility outcome after expectant management of ectopic pregnancy

Objective: To study tubal patency and fertility outcome of patients with expectantly managed ectopic pregnancy (EP).

Design: A prospective study.

Setting: Department of Obstetrics and Gynecology, Turku University Central Hospital, Turku, Finland.

Patient(s): Thirty patients who wanted to become pregnant again were treated successfully by expectant management of EP.

Intervention(s): Patients were examined with posttreatment hysterosalpingography, and they filled out a questionnaire about their subsequent pregnancies.

Main Outcome Measure(s): Free passage through open lumen showing tubal patency; number of full-term pregnancies and EPs revealing relative rate of subsequent fertility.

Result(s): A free passage through the diseased tube was seen in 93% of the cases (28 of 30). Two of the 24 patients (8.4%) who wanted to become pregnant had an obstruction in the diseased tube. One (4.2%) of them had a normal opposite tube and later had a normal pregnancy. The other (4.2%) had an obstruction in both tubes and subsequently had a repeat EP. One of the 6 patients had an EP (this patient did not want to become pregnant and did not use contraception). However, her posttreatment hysterosalpingography was normal. In total, the subsequent pregnancy rate was 88% (21 of 24), and the rate of repeat EP was 4.2% (1 of 24).

Conclusion(s): Patients who are treated with expectant management have a good long-term fertility outcome. Spontaneous regression of EP does not lead to increased harm or damage to the tube, i.e., the risk for repeat EP is low.     

Groove pancreatitis associated with true pancreatic cyst

We report a case of groove pancreatitis (GP) associated with a true pancreatic cyst. An 81-year-old man who had suffered epigastric pain for 4 months was referred to Saisekai Kure Hospital. Computed tomography and endoscopic retrograde pancreatography showed a cystic lesion in the groove area of the pancreas. Serum amylase elevation and imaging findings suggested GP due to the cyst. Six weeks of medical treatment did not improve the clinical symptoms. Therefore, pancreatoduodenectomy was performed. Histologic examination revealed a true cyst with intraluminal necrosis, which produced a protein plug that obstructed the Santorini duct. The parenchyma surrounding the groove area showed marked fibrosis and inflammatory cell infiltration. GP due to true pancreatic cyst was diagnosed. Although GP is usually caused by overconsumption of alcohol, which leads to changes in the pancreatic juice and the ultimate blockage of pancreatic outflow, the histologic features in our patient suggest that true pancreatic cyst stands as a secondary cause of GP.     

Multiple sclerosis and headache co-morbidity. A case-control study

The prevalence of primary headache (PH) in a multiple sclerosis (MS) sample vs. control healthy subjects was investigated at a neurological clinic in 2004–2005: 122 of 238 (51%) MS patients and 57 of 238 (23%) controls proved to be affected by headache. The groups did not differ for the rates of PH types. Headache types of MS patients were comparable to those of PH patients that were observed at the same institute in a case-control comparison. First symptoms of headache preceded those of MS in two thirds of cases. Headache features did not significantly change after MS onset. Comorbidity of MS and PH could be explained by some common clinical and biological traits.     

Interpreting cerebrospinal fluid pleocytosis in HIV in the era of potent antiretroviral therapy

Background  

Cerebrospinal fluid (CSF) pleocytosis may be seen in asymptomatic HIV-infected individuals. This finding complicates interpretation of CSF abnormalities when such individuals are evaluated for other central nervous system infections. The goal of this study was to determine the relationship between CSF pleocytosis, central nervous system (CNS) antiretroviral penetration, adherence to antiretroviral medication regimens, neurological symptoms and performance on neuropsychological tests.     

Definition of An Optimal First-line Chemotherapy in Metastatic Breast Cancer

Single-agent chemotherapy of metastatic breast cancer is the treatment of choice in patients with slow tumor progression and asymptomatic disease. In this patient group, the choice of drugs is based more on good tolerability than on efficacy. By contrast, symptomatic or rapidly progressing disease requires the use of highly active regimens where more weight is put on reliable antitumor activity. While anthraycline-based combination regimens have set the standard of effective treatment, the addition of docetaxel (and to a lesser extent paclitaxel) has improved tumor response, but failed to induce a consistent prolongation of survival. Based on retrospective analyses, it is hypothesised that the combined use of anthracyclines and taxanes in first-line therapy may be most beneficial in defined subgroups: after adjuvant chemotherapy, in patients with HER-2 gene amplification, possibly also in patients with rapidly progressing visceral disease.
