BACKGROUND: Fever is a very common complication that has been related to poor outcomes after aneurysmal subarachnoid hemorrhage (aSAH). The incidence of acalculous cholecystitis is reportedly 0.5%–5% in critically ill patients, and cerebrovascular disease is a risk factor for acute cholecystitis (AC). However, abdominal evaluations are not typically performed for febrile patients who have recently undergone aSAH surgeries. In this study, we discuss our experiences with febrile aSAH patients who were eventually diagnosed with AC. METHODS: We retrospectively reviewed 192 consecutive patients who underwent aSAH from January 2009 to December 2012. We evaluated their characteristics, vital signs, laboratory findings, radiologic images, and pathological data from hospitalization. We defined fever as a body temperature of >38.3℃, according to the Society of Critical Care Medicine guidelines. We categorized the causes of fever and compared them between patients with and without AC. RESULTS: Of the 192 enrolled patients, two had a history of cholecystectomy, and eight (4.2%) were eventually diagnosed with AC. Among them, six patients had undergone laparoscopic cholecystectomy. In their pathological findings, two patients showed findings consistent with coexistent chronic cholecystitis, and two showed necrotic changes to the gall bladder. Patients with AC tended to have higher white blood cell counts, aspartame aminotransferase levels, and C-reactive protein levels than patients with fevers from other causes. Predictors of AC in the aSAH group were diabetes mellitus (odds ratio [OR], 8.758; P = 0.033) and the initial consecutive fasting time (OR, 1.325; P = 0.024). CONCLUSIONS: AC may cause fever in patients with aSAH. When patients with aSAH have a fever, diabetes mellitus and a long fasting time, AC should be suspected. A high degree of suspicion and a thorough abdominal examination of febrile aSAH patients allow for prompt diagnosis and treatment of this condition. Additionally, physicians should attempt to decrease the fasting time in aSAH patients.

OBJECTIVES: Dysfunctional uterine bleeding(DUB) is defined as abnormal bleeding from the uterine endometrium unrelated to anatomic lesions of the uterus, and its incidence is 10-15% among gynecologic diseases. We conducted this study for understanding correlation between clinical aspecets and pathological findings of DUB. Methods: We conducted a retrospective review of 599 women with DUB who underwent endometrial biopsy with special regard to the relation between pathologic findings and presenting symtoms or complaints from Jan. 1988 to Dec. 1997. RESULTS: Age distribution of DUB was mainly 5th decade, mean age was 44.1years, among various bleeding patterns, intermenstrual bleeding was the most common pattern(31.6%) and the next was menorrhagia(25.0%). Histologic findings of endometrium were proliferative phase, 327 cases(54.6%), hyperplasia, 139 cases(23.2%), secretory phase, 74 cases(12.4%) in order of frequency, and there was no difference in distribution of histologic findings among various bleeding patterns. CONCLUSION: Compared to other previoius studies, our study showed more incidence of endometrial hyperplasia, especially at age group of 40 or more. So patients aged more than this age with abnormal uterine bleeding must undergo emdometrial biopsy for pathologic diagnosis. Patients who are diagnosed endometrial hyperplasia must be carefully followed up because there are possibilities of progression to endometrial carcinoma.

The fate of testicular salvage in spermatic cord torsion depends on the duration of ischemia and the degree of torsion. Even though spermatic cord torsion (SCT) can occur at any age, it is rarely reported in older patients. If the physician does not pay close attention to this unusual situation, the lack of suspicion for SCT may result in a missed or delayed diagnosis. We report a very uncommon case of missed SCT occurring in a 63-year-old man.

Cardiac papillary fibroelastomas are the second most common primary cardiac tumor. This tumor is usually benign and it involves the cardiac valve. However, most cardiac papillary fibroelastomas originate from a single site, and the incidence of cardiac papillary fibroelastomas originating from multiple sites is very rare (5%). A 55-year-old woman who presented with momentary dizziness and syncope was evaluated by performing echocardiography. Multiple tumors attached to the aortic valve were noted. The mass was removed freely without leaving any defect on the aortic valve leaflet. After the recovery period, the patient is currently being followed up at the outpatient department.

Background and Objectives:
Brugada syndrome (BrS) is an inherited arrhythmia syndrome that presents as sudden cardiac death (SCD) without structural heart disease. One of the mechanisms of SCD has been suggested to be related to the uneven dispersion of transient outward potassium current (Ito ) channels between the epicardium and endocardium, thus inducing ventricular tachyarrhythmia. Artemisinin is widely used as an antimalarial drug. Its antiarrhythmic effect, which includes suppression of Ito channels, has been previously reported. We investigated the effect of artemisinin on the suppression of electrocardiographic manifestations in a canine experimental model of BrS.
Methods:
Transmural pseudo-electrocardiograms and epicardial/endocardial transmembrane action potentials (APs) were recorded from coronary-perfused canine right ventricular wedge preparations (n=8). To mimic the BrS phenotypes, acetylcholine (3 μM), calcium channel blocker verapamil (1 μM), and Ito agonist NS5806 (6–10 μM) were used.Artemisinin (100–150 μM) was then perfused to ameliorate the ventricular tachyarrhythmia in the BrS models.
Results:
The provocation agents induced prominent J waves in all the models on the pseudoelectrocardiograms. The epicardial AP dome was attenuated. Ventricular tachyarrhythmia was induced in six out of 8 preparations. Artemisinin suppressed ventricular tachyarrhythmia in all 6 of these preparations and recovered the AP dome of the right ventricular epicardium in all preparations (n=8). J wave areas and epicardial notch indexes were also significantly decreased after artemisinin perfusion.
Conclusions
Our findings suggest that artemisinin has an antiarrhythmic effect on wedge preparation models of BrS. It might work by inhibition of potassium channels including Ito channels, subsequently suppressing ventricular tachycardia/ventricular fibrillation.

BACKGROUND: Airway hyperresponsiveness (AHR) to direct stimuli, such as methacholine (MCh), is observed not only in asthma but other diseases. AHR to indirect stimuli is suggested to be more specific for asthma. The purpose of this study was to determine whether asthmatic airway inflammation is more closely related to AHR to hypertonic saline (HS), an indirect stimulus, than to MCh. METHODS: Sixty-four consecutive adult patients with suspected asthma (45 asthma and 19 non-asthma) performed a combined bronchial challenge and sputum induction with 4.5% saline, and MCh challenge on the next day. RESULTS: Both HS-PD15 and MCh-PC20 were significantly lower in asthma patients than in non-asthma patients. However, the sensitivity/ specificity for asthma was 48.9%/100%, respectively, in the HS test and 82.2%/ 84.2%, respectively, in the MCh test. There was a significant relationship between HS-PD15 and MCh-PC20 and only 52.9% of patients with MCh-PC20 < or= 4 mg/mL showed HS-AHR, but 4 patients with HS-AHR showed MCh-PC20 > 4 mg/mL. There were significant correlations between both HS-PD15 and MCh-PC20 and FEV1, or sputum eosinophils, but FEV1 was more closely related to MCh-PC20 (r=0.478, p < 0.01) than to HS-PD15 (r=0.278, p < 0.05), and sputum eosinophils were more closely related to HS-PD15 (r=-0.324, p < 0.01) than to MCh-PC20 (r=-0.317, p < 0.05). Moreover, the IL-5 level (r=-0.285, p < 0.05) and IFN-gamma/IL-5 ratio (r=0.293, p < 0.05) in sputum were significantly related to HS-PD15, but not to MCh-PC20. CONCLUSION: HS-AHR may reflect allergic asthmatic airway inflammation more closely than MCh-AHR.

OBJECTIVE: Recently some reports suggested substance P and CGRP might be important factors for inflammation and hyperalgesia. This study was performed to see whether substance P or CGRP containing nerve fibers might be changed by mustard oil-induced inflammation. METHODS: After injection of mustard oil(5%) into uterine lumen, the uteri were removed and examined with immunohistochemical methods for substance P and CGRP. RESULTS: In the normal uterus, most of the substance P- or CGRP-immunoreactive nerve fibers were observed along the vascular structure and some in the myometrium, only few in the endometrium. Mustard oil did not changed this pattern of nerve fiber distribution but after 48 hrs, the amount of substance P or CGRP immunoreactive nerve fibers were greatly reduced compared with the normal uterus. It is not clear whether the decrease of substance P and CGRP immunoreactive fibers in the uterus was resulted from the depletion of the neuropeptides in the nerve fibers or the retraction of nerve fibers. CONCLUSIONS: These results suggest that the inflammation should cause the change of nerve fibers included in the nociception. This change may attribute the generation of inflammation and inflammatory hyperalgesia.

Pilomatricoma is a benign adnexal tumor, differentiating towards elements of the hair matrix and shaft. The tumor typically presents as a solitary, deep-seated, firm nodule with overlying normal epidermis. Herein, we report three cases of pilomatricomas with the dermal bullae overlying tumors. Histopathological examination of the lesions showed marked lymphatic dilatations, edema, and attenuated collagen and elastic fibers above the pilomatricomas in the upper dermis. We diagnosed them as lymphangiectatic pilomatricomas.
