RESUMO
A preoperative diagnosis of the peripheral small lung nodule is often difficult, and an intraoperative frozen section diagnosis (FSD) is performed to guide treatment strategy. However, invasive mucinous adenocarcinoma (IMA) is prone to be overlooked because of the low sample quality and weak atypia. We herein report a case of IMA, in which touch imprint cytology (TIC) revealed diagnostic efficacy. A 74-year-old male with a small, subsolid nodule in the right upper lobe underwent a thoracoscopic wedge resection. A grayish brown, 10 × 7 mm-sized nodule was observed on the cut surface. Intraoperative FSD revealed lung tissue with mild alveolar septal thickening and stromal fibrosis but without overt atypia. Meanwhile, TIC revealed mucus and a few epithelial cells with intranuclear inclusions, which pathologists evaluated as reactive. Finally, focal organizing pneumonia was tentatively diagnosed, and surgery was finished without any additional resection. However, permanent section diagnosis revealed a microinvasive mucinous adenocarcinoma. Nuclear inclusions were confirmed in tumor cells. In the intraoperative setting, TIC may be more advantageous than FSD in observing nuclear inclusions and mucus. Mucinous background and nuclear inclusion on TIC may suggest IMA even if FSD does not suggest malignancy in an intraoperative diagnosis of the peripheral small lung nodule.
RESUMO
Endoscopic ultrasound-guided fine-needle aspiration has become the common procedure for the diagnosis of pancreatic mass, and cytological examination is usually the first approach. Solid pseudopapillary neoplasm (SPN) cytologically represents papillary structures of branching capillaries surrounded by discohesive neoplastic cells. However, it may present various degrees of tissue degeneration, causing diagnostic challenges. Here, we report a 21-year-old female who had a 2-cm-sized mass in the pancreas head. Cytological examination revealed clumps of small round/oval cells that represented microcystic configurations with mucus, mimicking adenoid cystic carcinoma or mucinous adenocarcinoma. Cercariform cells, nuclear grooves/folding, and cytoplasmic vacuoles were not observed. Histopathological examination revealed confluent small glandular structures containing acidic mucus. The tumor cells were positively stained for ß-catenin, CD10, and CD56, and negative for chromogranin A and E-cadherin, suggesting SPN, micropseudocystic variant. This variant has been scarcely described, but we should recognize it for accurate cytological triage of pancreatic tumors.

BACKGROUND: Epidermodysplasia verruciformis is a rare genodermatosis characterized by a unique susceptibility to cutaneous human papillomaviruses infection. Most patients show autosomal recessive patterns of inheritance. CASE PRESENTATION: We report a case of two sisters with clinically epidermodysplasia verruciformis specific lesions on the face, neck, trunk, and extremities. PCR analysis indicated the presence of human papillomavirus type 5 in the lesions. Electron microscopic examination showed viral-like particles in keratinocyte nuclei and the stratum corneum of the epidermodysplasia verruciformis lesions. In addition, we examined the EVER1 and EVER2 genes using eight different primer pairs without finding any nonsense or frameshift mutations in the gDNA from lymphocytes of the elder sister. CONCLUSIONS: In this report, the patient's parents did not have epidermodysplasia verruciformis lesions or a consanguineous marriage. EV did not develop in the elder sister until five years of age, so the parents did not perceive EV as an inherited disease. The probability that EV developed in both sisters was only 6.25%. Thus, it is rare for both sisters to develop epidermodysplasia verruciformis lesions considering that the parents were presumed to be carriers and the disease reveal an autosomal recessive pattern of inheritance.

The Palliative Care Unit at Heiwa Hospital has 16 beds, and offers inpatient support in general wards, as well as back-up beds in emergencies in collaboration with local home care support clinics. For two years from January 2012 to December 2013, there were 1,213 cases where patients were seen for initial outpatient visits at the Department of Palliative Care. At the time of the initial visit, visiting medical care had been introduced for 25% of the cases. Although 59% of the patients who visited our department are hospitalized, 20% of inpatients have been hospitalized at the request of their home care physician. The availability of back-upbeds offers patients and their families, as well as related medical institutions, a sense of security, and enables home care to continue. The significance of back-upbeds will become even more important in the future.

More than 150 types of Human papillomaviruses (HPVs) have been isolated from numerous cutaneous and/or mucosal lesions. Flat wart samples on the face from 36 immunocompetent patients were collected and screened for HPV. From one sample, we cloned a putative novel genotype. The novel type consisted of 7779 bp in length with a GC content of 47.1%, containing open reading frames for putative early proteins (E1, E2, E4, E6, and E7) and two late proteins (L1 and L2). Homology searches and phylogenetic analyses indicated that it belonged to Alphapapillomavirus (Alpha-PV) species 2 and most closely resembled HPV 3. The virus fulfilled the definition of a novel type, and was named HPV 160 by the Reference Center for Papillomaviruses. The putative E7 protein of HPV 160 as well as HPV 29, 77, and 78 contained the Leu-X-Cys-X-Glu pRB-binding motif but other Alpha-PV species 2 (HPV 3, 10, 28, 94, 117, and 125) did not have this conserved motif.

We have been practicing palliative care for terminal cancer patients at outpatient sections, patient wards, by home care, and by visiting nursing stations for the last 4 years. After the establishment of our palliative care unit in June 2011, it became difficult for us to provide sufficient home care support by ourselves, because of the increasing number of the patients and their widespread locations. It is therefore necessary to cooperate with regional medical clinics in order to support the patients who need home care even after their condition deteriorates. To determine the extent to which the home care-supporting clinics perform palliative care, we used an original questionnaire. Twenty-five clinics agreed to the publication of their names as our cooperating clinics. The number of patients who received palliative care at home from home care clinics after visiting our hospital increased from 8% to 14%, and the rate of patients who died at home also increased from 10% to 13%. Information about cooperating with home care clinics is very important and the improvement of palliative care skills necessary for home care doctors to continue their support for End-Of-Life cancer patients. Furthermore, the hospital should offer a strict and timely backup when the condition of patients treated at home suddenly deteriorates.

BACKGROUND: Specific substance of Maruyama (SSM) is a carcinostatic immunotherapeutic agent extracted from Mycobacterium tuberculosis. The efficacy of SSM induced interleukin(IL)-12 and IFN-γ production, and inhibition of IL-4, resulting in a shift from Th2 to Th1 in vivo. OBJECTIVE: The DS-Nh mice are a model of human atopic dermatitis (AD), which spontaneously develop dermatitis under conventional conditions. In this study, to determine whether SSM can prevent the development of skin lesions in a murine model of AD. METHODS: DS-Nh mice were injected with SSM 5 days per week for 11 weeks. Pharmacological, histological and serological studies were performed to investigate the therapeutic effect of SSM for DS-Nh mice. Analysis of cytokines responses to SSM using quantitative RT-PCR and flow cytometry were also performed to evaluate their therapeutic mechanisms in these AD model mice. RESULTS: Clinically, erythema, erosions, excoriation, and edema were observed in DS-Nh mice at 16 weeks of age, which advanced with age. Histologically, the relative number of mast cells increased in DS-Nh mice. SSM treatment alleviated the clinical and histological findings in accord with reduced serum IgE level, and increased IgG2a level. TSLP expression was not induced, but IL-1ß, IL-12, IL-17A, and IFN-γ were induced in SSM-treated DS-Nh mice. Overall, SSM treatments increased the number of activated DCs in lesions. SSM induced CD80, CD86, and MHC class II expression on bone marrow-derived DCs. CONCLUSIONS: SSM enhanced IL-12 production, but suppressed TSLP expression, resulting in a shift from Th2 to Th1 responses. This shift suppressed AD-like skin lesions in a similar fashion as the BCG vaccine. Therefore, SSM may be a useful adjuvant for suppressing skin lesions in AD models.

BACKGROUND: Various laser therapies have been used to treat viral warts, and numerous successful results have been reported, but plantar warts are notoriously difficult to treat and eradicate. MATERIALS & METHODS: This study included 35 lesions in 31 patients (17 female, 14 male) with plantar warts. We used a carbon dioxide (CO2) laser for incisions, and the defect was covered with artificial dermis. Follow-up periods ranged from 3 to 12 months. Overall, we examined the presence or absence of human papillomaviruses (HPVs) DNA in the lesional skin of all cases and at the excisional site after treatment in 20 cases. RESULTS: Thirty-one of 35 lesions (88.6%) achieved complete clearance after one treatment session. We observed local recurrence in four lesions (11.4%). The application of salicylic acid was effective in treating minor recurrent cases. After complete remission, HPV DNA was not detected in the upper epidermis of the postoperative site. No significant scars or severe pain were seen in any patients. CONCLUSION: A combination of CO2 laser therapy and artificial dermis application effectively treated the majority of plantar warts after one treatment, with complete and rapid clearance and no persistent pain. The authors have indicated no significant interest with commercial supporters.

OBJECTIVE: To study the association between ear diseases and the ability of the middle ear to sense air pressure changes, we elucidated the appropriate conditions for measurements and confirmed the pressure-sensing regions while quantitatively assessing the pressure-sensing ability of normal ears and of ears with traumatic perforation of the tympanic membrane. METHODS: In 318 normal ears (159 volunteers), an air pressure of 40daPas(-1) was loaded on to the external auditory canals to measure the minimum pressure sensed by subjects as a result of air pressure changes. The minimum pressure was defined as the minimum sensory threshold for air pressure loading (MSTAP; daPa). In 40 of 318 normal ears (20 volunteers), the MSTAP was measured at 10daPas(-1). Next, topical anesthesia was administered to 5 normal ears (5 volunteers), and the MSTAP was measured. In 7 ears with traumatic tympanic membrane perforation (7 cases), the MSTAP was also measured at the first medical examination. The data were analyzed using Stat View 5.0 (SAS Institute Inc., Cary, NC, USA). To test the significance of the data, the Mann-Whitney U-test and the Wilcoxon test were used. RESULTS: The mean (+/-S.D.) MSTAP at 40daPas(-1) was -39.2+/-12.2daPa with negative pressure and 39.5+/-12.4daPa with positive pressure. At 10daPas(-1), the MSTAP was -70.3+/-25.0daPa with negative pressure and 72.5+/-22.7daPa with positive pressure, and both the mean and S.D. values were higher than those obtained at 40daPas(-1). Briefly, the MSTAP at 40daPas(-1) produced less variance than that at 10daPas(-1). The MSTAP demonstrated gender- and age-related variations. Moreover, it increased after topical anesthesia was administered to the tympanic membrane. The MSTAP in patients with traumatic tympanic membrane perforation was -205.0+/-26.3daPa with negative pressure and 206.0+/-26.7daPa with positive pressure, and was significantly higher than that observed in case of normal ears. CONCLUSION: For obtaining accurate measurements while estimating the pressure-sensing ability of the middle ear, the rate of pressure loading should be considered. Although we assume that the middle ear has pressure-sensing regions other than the tympanic membrane, we conclude that the tympanic membrane is the most sensitive pressure-sensing region in the middle ear.

BACKGROUND: It has been reported that the morbidity rate of vasospastic angina is higher in Japan compared to western countries, and its prognosis has already been reported. However, the prognosis of vasospastic angina in relation to coronary angiographic findings, prognostic risk factors and treatment has not yet been fully investigated. METHODS AND RESULTS: From January 2000 to October 2005, 1047 patients with vasospastic angina diagnosed by coronary angiography at Gifu University Hospital and related hospitals were registered in a cohort study (follow-up rate: 91.4%, median follow-up duration: 3.8 years). The presence of coronary artery stenosis, diabetes mellitus, total spasm, and age of more than 65 years had a negative prognostic impact on cardiovascular events. Patients were treated with calcium channel blockers such as diltiazem (CAS 33286-22-5, CAS 42399-41-7), amlodipine (CAS 111470-99-6), nifedipine (CAS 21829-25-4), and benidipine (CAS 91599-74-5). Among these calcium channel blockers, when patient background was matched by the propensity score in patients treated with calcium channel blockers only, the cardiovascular event rate was significantly lower in the benidipine group than in the diltiazem group. CONCLUSION: The study demonstrated for the first time that total spasm is a risk factor, independent of other factors, for cardiovascular events in patients with vasospastic angina. Treatment with benidipine showed a better prognosis than that with diltiazem.

Free oligosaccharides (FOSs) in the cytosol of eukaryotic cells are mainly generated during endoplasmic reticulum (ER)-associated degradation (ERAD) of misfolded glycoproteins. We analyzed FOS of the nematode Caenorhabditis elegans to elucidate its detailed degradation pathway. The major FOSs were high mannose-type ones bearing 3-9 Man residues. About 94% of the total FOSs had one GlcNAc at their reducing end (FOS-GN1), and the remaining 6% had two GlcNAc (FOS-GN2). A cytosolic endo-beta-N-acetylglucosaminidase mutant (tm1208) accumulated FOS-GN2, indicating involvement of the enzyme in conversion of FOS-GN2 into FOS-GN1. The most abundant FOS in the wild type was Man(5)GlcNAc(1), the M5A' isomer (Manalpha1-3(Manalpha1-6)Manalpha1-6(Manalpha1-3)Manbeta1-4GlcNAc), which is different from the corresponding M5B' (Manalpha1-2Manalpha1-2Manalpha1-3(Manalpha1-6)Manbeta1-4GlcNAc) in mammals. Analyses of FOS in worms treated with Golgi alpha-mannosidase I inhibitors revealed decreases in Man(5)GlcNAc(1) and increases in Man(7)GlcNAc(1). These results suggested that Golgi alpha-mannosidase I-like enzyme is involved in the production of Man(5-6)-GlcNAc(1), which is unlike in mammals, in which cytosolic alpha-mannosidase is involved. Thus, we assumed that major FOSs in C. elegans were generated through Golgi trafficking. Analysis of FOSs from a Golgi alpha-mannosidase II mutant (tm1078) supported this idea, because GlcNAc(1)Man(5)GlcNAc(1), which is formed by the Golgi-resident GlcNAc-transferase I, was found as a FOS in the mutant. We concluded that significant amounts of misfolded glycoproteins in C. elegans are trafficked to the Golgi and are directly or indirectly retro-translocated into the cytosol to be degraded.

Peptide:N-glycanase (PNGase) is the enzyme responsible for de-N-glycosylation of misfolded glycoproteins in the cytosol. Here, we report the molecular identification and characterization of PNGase (png-1, F56G4.5) from Caenorhabditis elegans. This enzyme released both high mannose- and complex-type N-glycans from glycopeptides and denatured glycoproteins. Deglycosylation activity was inhibited by Zn(2+) and z-VAD-fmk, but not by EDTA. PNG-1 has a thioredoxin-like domain in addition to a transglutaminase domain, the core domain of PNGases, and exhibited protein disulphide reductase activity in vitro. Our biochemical studies revealed that PNG-1 is a unique bifunctional protein possessing two enzyme activities.

CONCLUSIONS: This study revealed two characteristic findings of the feeling of ear fullness (FEF) in acute sensorineural hearing loss (ASNHL). First, that the appearance of FEF was not associated with the auditory function on audiograms; and second, that the disappearance of FEF is clearly associated with the hearing prognosis. OBJECTIVE: FEF appears frequently in patients with ASNHL. However, there are few reports on this symptom and its mechanism has yet to be clarified. So we tried to investigate the character of FEF in ASNHL. PATIENTS AND METHODS: In this study, observations were made during the period from the first medical examination to 2 months after obtaining a steady audiogram on 227 ears from unilateral ASNHL cases, and the relationship between FEF and the audiograms was analyzed. RESULTS: The FEF prevalence at the first medical examination was about 80% for any audiogram shape or hearing threshold. Moreover, the better the hearing prognosis, the higher the improvement rate of FEF.

BACKGROUND: Antiandrogens used to treat benign prostatic hyperplasia (BPH) may affect the diagnosis of prostate cancer by decreasing serum prostate-specific antigen (PSA) values. We conducted a retrospective survey of BPH patients treated with chlormadinone acetate (CMA) and analysed the effect of CMA on their PSA values. METHODS: A chart-based, retrospective, multi-institutional survey of clinically diagnosed patients with BPH who had been treated with CMA (Prostal; 50 mg/day) was conducted. The patients were divided into three groups according to their baseline PSA values: <4 ng/mL, Group I; >or=4 ng/mL and <10 ng/mL, Group II; and >or=10 ng/mL, Group III. The changes in the PSA values from baseline after 16, 26, and 52 weeks of CMA therapy were predicted using a nonlinear regression model analysis. RESULTS: Data from 192 of the 303 enrolled patients were analysed. The predicted percent changes from baseline among all patients after 16, 26, and 52 weeks of treatment were -49.6%, -49.8%, and -49.9%, respectively. The corresponding values were -42.4%, -43.7% and -43.8% in Group I; -57.4%, -58.4% and -58.5% in Group II; and -50.6%, -50.6% and -50.6% in Group III, respectively. CONCLUSION: The PSA values reached a nadir, approximately -50% of the baseline, after 16 weeks of CMA administration and remained at the same level thereafter. When CMA is used to treat BPH patients, the possibility of abnormal increases in PSA associated with prostate cancer must be considered; if prostate cancer is suspected, prompt testing, including a biopsy, should be performed.

A study was conducted to assess the effectiveness of trivalent influenza vaccine in preventing influenza and reducing absenteeism in health-care workers of Gifu Red Cross Hospital during the 2002-2003 influenza season. Questionnaires were distributed to 370 health-care workers, and 366 were returned showing that 237 had received influenza vaccine and 129 were unvaccinated. The criterion for influenza was febrile episodes with a positive reaction on a rapid antigen detection test. Among vaccine recipients, the number of influenza infections was 3.4 per 100 subjects, compared with 8.5 per 100 subjects in nonrecipients (P = 0.034), and the number of days absent from work per 100 subjects was 9.5, compared with 15.1 per 100 subjects in nonrecipients (P = 0.0003). The prevalence of adverse reactions to the vaccine was rather low. No serious adverse reactions were recorded and no one was absent from work because of adverse reactions. It is concluded that influenza vaccine is effective in preventing influenza and reducing absenteeism in health-care workers. The results of this study support recommendations for influenza vaccination in health-care workers.

Introduction: Conditions that cause curvature of the erect penis also lead to difficulties with intercourse. The present study presents an effective surgical treatment for congenital penile curvature. Methods: Between March 1996 and August 2004, 49 patients were diagnosed with congenital penile curvature at the Toho University Omori Hospital Reproduction Center, Tokyo. Of these, 27 eligible patients underwent surgical treatment. The operative technique used involved the tunica albuginea being exposed and a number of vertical incisions were made through its superficial layers. The superficial layer of the tunica albuginea was then resected using scissors. Inverted plication sutures were then placed in the raw surface of the corpus cavernosum using 2-0 nylon. In addition, 2-0 polyglactic acid (Vicryl) sutures were placed on either side of each nylon suture knot. Results: Of a total of 49 patients, 27 eligible patients underwent surgical treatment with no serious postoperative complications. All 27 patients were able to sustain intercourse. There were no new cases of erectile dysfunction, penile pain or penile shortening. There were no recurrences of penile curvature. Conclusions: This new partial thickness shaving, inverted sutures reinforced with dissolving sutures plication method is an extremely effective surgical treatment for congenital penile curvature, with a superior safety profile.

RESUMO
Sudden sensorineural hearing loss (SSNHL) remains a controversial problem with respect to etiology and the factors that might predict prognosis. We used logistical regression analysis to determine which factors are most strongly related to outcome for patients with SSNHL. In so doing, we employed a retrospective chart-review study. The study group consisted of 296 patients (296 ears). The outcome of SSNHL was cured (full recovery) in 64, recovered (partial recovery) in 175, and no change in 57. We performed separate analyses on those in the no-change and partial-recovery groups and on those in the no-change and full-recovery groups. The following factors were studied as explanatory variables: age; number of days until presentation; vestibular symptom; initial mean hearing level at 0.25 kHz, 0.5 kHz, 1 kHz, 2 kHz, and 4 kHz; and treatments (steroids, satellite ganglion block). In the first analysis, for patients in the no-change and recovered groups, the factors most strongly related to outcome were the number of days until presentation and age. The second analysis, for the nochange and cured groups, revealed that the number of days until presentation, vestibular symptom, age, and initial mean hearing level were most strongly related to outcome. Our results will increase the ability to predict the outcome for SSNHL.
