Is septoplasty required whenever anterior septal deviation is present?

OBJECTIVE: Post-operative success and patient satisfaction were assessed following septoplasty for mild to severe anterior septal deviation. METHODS: The study included patients with an anterior nasal septal deviation in the form of a 'C' shape and close to the nasal valve in the anterior septal area. Deviation severity was classified as severe (group 1), moderate (group 2) or mild (group 3). Open or closed septoplasty procedures were performed. All patients were surveyed twice using the Nasal Obstruction Symptom Evaluation scale and the 36-Item Short Form Health Survey. RESULTS: The mean Nasal Obstruction Symptom Evaluation score for group 1 was 15.58 ± 2.34 prior to surgery and 6.61 ± 3.29 following surgery. The corresponding pre- and post-surgery scores in group 2 were 11.9 ± 2.82 and 6.3 ± 3.03, respectively. In group 3, these values were 8.28 ± 2.63 and 7.12 ± 3.18, respectively. The mean 36-Item Short Form Health Survey physical function value for groups 1 and 2 increased after surgery; in group 3, this value decreased after surgery, but the result was not statistically significant. CONCLUSION: Septoplasty is very successful for treating moderate or advanced deviations, but great care should be taken when employing septoplasty for mild deviations.

Therapeutic potential of cristobalite in the treatment of calf diarrhea.

Calf diarrhea continues to be the major problem of calves in the neonatal period. The effect of zeolites has been increasingly studied in ruminant health in recent years. In the present study, the efficacy of cristobalite, a zeolite, in neonatal calf diarrhea was studied first time. For this purpose, twenty-five neonatal calves with diarrheas were divided into two groups, and Group 1 (n=12) received conventional treatment and Group 2 (n=13) received cristobalite (Zoosorb 10 mg/kg) orally 3 times a day in addition to conventional treatment. Escherichia coli k99 and CS31a, bovine rotavirus and bovine coronavirus were isolated from fecal samples at the beginning of the treatment, on the third day and before discharge. It was determined that the recovery period in Group 2 was 0.95 (20.6%) days shorter than in Group 1 (p⟨0.05) while no viral agents were found on the fifth day in Group 2, viral shedding continued in 4 of 5 calves in Group 1. In conclusion, the study revealed that cristobalite speeds the recovery time and possibly decreases viral shedding in neonatal calf diarrhea, demonstrating a remarkable efficiency in the treatment.

Allergic rhinitis and arterial blood pressure: a population-based study.

OBJECTIVES: To investigate the likelihood of allergic rhinitis and potential co-morbidities, and to assess whether allergic rhinitis is associated with arterial blood pressure and hypertension. METHODS: In this population-based study, 369 adults with allergic rhinitis and asthma were assessed via a questionnaire and immunoglobulin E levels. There were four groups: control (n = 90), allergic rhinitis (n = 99), asthma (n = 87) and hypertension (n = 93). Arterial blood pressure was measured in all groups. RESULTS: There were no significant differences in systolic or diastolic blood pressure between males and females in any group. Pairwise comparisons revealed no significant differences between: the control and allergic rhinitis groups, the control and asthma groups, or the allergic rhinitis and asthma groups. The systolic and diastolic blood pressure values of males and females were significantly higher in the hypertension group than the allergic rhinitis group. There were no significant differences in systolic blood pressure or diastolic blood pressure for seasonal and perennial allergic rhinitis patients. CONCLUSION: Rhinitis was not associated with increased blood pressure. Allergic rhinitis can coincide with asthma and hypertension. The findings do not support the need for blood pressure follow up in allergic rhinitis patients.

Atypical Leiomyomas of the Uterus: A Clinicopathologic Study of 54 Cases and an Immunohistochemical Analysis of Ki-67 and p53 / Leiomiomas atípicos del útero: un estudio clínico-patológico de 54 casos y un análisis inmunohistoquímico de Ki-67 y p53

ABSTRACT Objective: Uterine atypical leiomyomas (ALs) are extremely rare and occur in an age group almost one decade earlier than that for leiomyosarcomas. According to the literature, extensive clinicopathologic studies on ALs were limited to only two studies (2, 8). Atypical leiomyomas of the uterus are well-defined neoplasms with smooth muscle cells. The aim of this study was to investigate clinicopathologic findings in 54 cases diagnosed with ALs as well as Ki-67 and p53 expressions immunohistochemically. Methods: Fifty-four cases diagnosed between 2000 and 2013 were included. The histological and clinical features of the cases were reviewed, and their medical records were examined. Ki-67 and p53 were performed on all cases immunohistochemically. Results: The average age of the patients was 41.8 years. The average clinical follow-up period was 57 months. Hysterectomy was performed in 31 patients, and myomectomy in 21 patients, while resection of the mass was performed in two patients due to the intraligamentary mass. The average size of the neoplasms was 6.2 cm. Severe cellular atypia was noticed in 25 patients. While the number of mitoses was 1/10 high power field in 30 patients, it was 4/10 high power field in six patients. Ki67 was found to be positive in 50 patients at the rate of 1-5% immunohistochemically, while p53 demonstrated staining at the ratio of 10-15% staining in four patients. Conclusion: The differentiation of ALs from leiomyosarcomas is crucial. The recurrence rate after follow-up is 2%. In our opinion, the patients diagnosed with 'AL with limited experience' before should be correctly diagnosed as AL. We recommend that Ki-67 and p53 can be used as adjuvant markers immunohistochemically in the patients where a problem in differential diagnosis from leiomyosarcoma exists.

RESUMEN Objetivo: Los leiomiomas atípicos uterinos (LA) son extremadamente raros y se presentan en un grupo de edad casi una década antes que los leiomiosarcomas. De acuerdo con la literatura, los extensos estudios clínico-patológicos en los LA se limitaron a sólo dos estudios (2, 8). Los leiomiomas atípicos del útero son neoplasmas bien definidos con células de músculo liso. El objetivo de este estudio fue investigar los hallazgos clínico-patológicos en 54 casos diagnosticados con LA, así como las expresiones Ki-67 y p53, de forma inmunohistoquímica. Métodos: Se incluyeron cincuenta y cuatro casos diagnosticados entre 2000 y 2013. Se revisaron las características histológicas y clínicas de los casos y se examinaron sus historias clínicas. Ki-67 y p53 se realizaron en todos los casos de forma inmunohistoquímica. Resultados: La edad promedio de los pacientes fue de 41.8 años. El período promedio de seguimiento clínico fue de 57 meses. Se realizaron histerectomías a 31 pacientes, y miomectomías a 21 pacientes, en tanto que a dos pacientes se les realizó resección de la masa debido a la situación intraligamentosa. El tamaño promedio de los neoplasmas fue de 6.2 cm. Se observó atipia celular severa en 25 pacientes. El número de mitosis fue de 1/10 campos de gran aumento en 30 pacientes, en contraste con el número de mitosis de 4/10 campos de gran aumento en seis pacientes. Se encontró que Ki67 fue positivo en 50 pacientes a razón de 1-5% inmunohistoquímicamente, mientras que p53 mostró tinción a razón de 10-15% de tinción en cuatro pacientes. Conclusión: La diferenciación de LA entre los leiomiosarcomas es crucial. La tasa de recurrencia después del seguimiento es de 2%. En nuestra opinión, los pacientes diagnosticados con 'LA con experiencia limitada ' antes, deben ser diagnosticados correctamente como LA. Recomendamos que Ki-67 y p53 sean usados como marcadores adyuvantes inmunohistoquímicamente en los pacientes con un diagnóstico diferencial de leiomiosarcoma.

The association of the microcystic, elongated and fragmented (MELF) invasion pattern in endometrial carcinomas with deep myometrial invasion, lymphovascular space invasion and lymph node metastasis.

The purpose of this study was to investigate the frequency of microcystic, elongated and fragmented (MELF) pattern of invasion in endometrioid endometrial adenocarcinomas (EA) and its association with prognostic factors. Stained tissue sections from 121 cases of EA (total hysterectomy and pelvic, with or without para-aortic, lymphadenectomy specimens) were reviewed to identify cases showing MELF-type invasion. The prognostic factors of low tumour grade, deep myometrial invasion (MI), cervical stromal involvement, lymphovascular space invasion (LVSI), lymph node (LN) metastasis and advanced clinical stage were more frequently observed in MELF-positive cases (p < 0.05). Thus, MELF-positive cases had an increased frequency (28/121) of these prognostic factors, which has implications in routine clinical practice, as it signals the importance of recognising MELF pattern invasion. In univariate analysis, MELF positivity, deep MI, cervical stroma involvement and LVSI were significantly related to LN metastasis (p < 0.05). However, in multivariate analysis, only MELF pattern invasion and cervical stroma involvement were independent factors for LN metastasis. Nevertheless, further studies are needed to evaluate the clinical significance of MELF pattern of invasion in endometrial adenocarcinoma.

The importance of immediate verification of a cervical cytological abnormality with histology.

BACKGROUND: A serious proportion of the patients with invasive cervical cancer can be women who have had abnormal smear findings known for at least 6 months. AIMS: The aims of the study were to evaluate the cervical cytohistopathologic correlation in the population studied, and to discuss the acceptability of immediate histological verification for minor Papanicolaou smear abnormalities. MATERIALS AND METHODS: A total of 443 patients who were admitted with abnormal smear results and had undergone immediate colposcopy, cervical biopsy and endocervical curretage in the gynecologic oncology clinic between the years of 2003-2009 were enrolled into the present retrospective study. One-way analysis of variance and independent t-tests were used to study the results. RESULTS: The distribution of abnormal smear results were documented as 46.27%, 29.57%, 13.76%, 7.67%, 1.58%, 0.67%, and 0.45% for atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H), squamous cell carcinoma (SCC), atypical glandular cell (AGC), and adenocarcinoma, respectively. The percentages of cervical intraepithelial neoplasia grade 2-3 (CIN 2-3) and greater lesions were 70.49%, 35.29%, 15.26%, and 9.75% for HSIL, ASC-H, LSIL, and ASC-US, respectively. Moreover, 38.36% of all the CIN 2-3 or cancer (n = 104) cases originated from those with low grade referral diagnosis (ASC-US and LSIL). CONCLUSIONS: The majority of cases in the study were predominantly ASC-US and LSIL and approximately 40% of all the high grade lesions came from those with low grade referral diagnosis. This shows poor cytohistopathological correlation and calls the triage of minor cytological abnormalities into question.

Investigation of Keyes skin biopsy instrument for cervical biopsy procedures versus Kevorkian biopsy forceps.

OBJECTIVE: We aimed to investigate the utility and efficacy of the Keyes skin biopsy instrument for cervical biopsy procedures. MATERIAL AND METHODS: A prospective clinical trial was conducted on 50 women with cervical lesions. Colposcopy-guided cervical biopsies were collected using a Keyes biopsy punch and a Kevorkian biopsy forceps and the two methods were compared with definitive histopathological examination of the specimens obtained by the loop electrosurgical excision procedure (LEEP), conization or hysterectomy. RESULTS: There were no differences in speed of collection, diagnostic value of specimens, complication rates, or sample quality. The sensitivity, specificity, positive and negative predictivity of specimens were all 100% for both methods. CONCLUSIONS: The Keyes biopsy punch was found to be a safe, rapid and accurate diagnostic tool in cervical biopsy procedures. Based on the results of this study, the use of a Keyes punch instrument can be recommended as an alternative to other cervical biopsy methods.

Uterine liposarcoma in a young woman: a case report.

Liposarcoma of uterus is a very rare neoplasm encountered generally in the sixth or seventh decade of life. We reported the eighth case of uterine liposarcoma with extension to broad ligament in a 23-year-old woman who presented with pelvic pain, dysuria, and rapidly enlarging pelvic mass. During laparotomy, the mass was detected to be originated from the uterine cervix. In frozen section, no definitive diagnosis was established, and for preservation of fertility, extirpation of the mass was performed. The histopathologic examination of the specimen revealed liposarcoma. The tumor cells were diffusely and intensively immune reactive for vimentin and S-100, and negative for smooth muscle actin, desmin, h-caldesmon, pan cytokeratin, and CD10. Staining with periodic acid and Schiff, alcian blue, mucicarmine, and epithelial membrane antigen (EMA) were negative. No recurrence was detected in the postoperative seventh month. Present case is the youngest patient with uterine liposarcoma and also the first case detected in reproductive period.

Utility of MIB-1 and estrogen and progesterone receptor in distinguishing between endometrial stromal sarcomas and endometrial stromal nodules, highly cellular leiomyomas.

It is difficult to differentiate between an endometrial stromal nodule (ESN) and endometrial stromal sarcoma (ESS) in curettage specimen, and the recommended therapy of endometrial stromal neoplasm is hysterectomy. If we could discriminate ESS from ESN in curettage specimens, there would be an opportunity to treat ESN by local excision rather than by hysterectomy. We analyzed MIB-1 and estrogen and progesterone receptor (ER/PR) expression in a retrospective series of 8 ESSs, 7 ESNs, and 17 highly cellular leiomyomas obtained from hysterectomy specimens. ESSs expressed MIB-1 more frequently than ESNs (P < 0.05), and ESSs had a tendency to express ER less frequently than ESNs (P= 0.08). We observed that in spite of showing MIB-1 expression to some extent, highly cellular leiomyomas usually could not reach ESSs' level and frequency of MIB-1 expression in the current study. Although MIB-1 and ER appear to be promising markers in the differential diagnosis of ESSs, a larger study would be necessary to confirm their validity.

Reporting of "LSIL with ASC-H" on cervicovaginal smears: is it a valid category to predict cases with HSIL follow-up?

Recently it has been shown that there is a 15-30% risk of associated cervical intraepithelial neoplasia (CIN 2-3 or greater) for a low-grade squamous intraepithelial lesion (LSIL) diagnosis. We tried to define a subgroup of "LSIL with atypical squamous cells of undetermined significance. High-grade squamous intraepithelial lesion (LASC-H)" in cervicovaginal screening which may aid in predicting the cases associated with high risk cannot be ruled out. In the years between 2001 and 2003 a total of 21,342 cervicovaginal smears were evaluated. The smears with pure LSIL and LASC-H diagnosis which had histologic follow-up were selected. The cases with diagnosis of LASC-H contained numerous typical cells of LSIL and only a few cells with features suggesting high-grade squamous intraepithelial lesion (HSIL). Eight (61%) of 13 cases with a diagnosis of LASC-H but three (11%) of 27 cases with a diagnosis of pure LSIL resulted in CIN 2-3 histology (p < 0.05). Diagnosis of LASC-H may be a valid diagnostic category in distinguishing patients with LSIL that would have HSIL in follow-up.

Immunohistochemical profile of intravenous leiomyomatosis.

To determine the immunohistochemical staining profile of intravenous leiomyomatosis (IVL), we analysed six IVLs and 12 ordinary leiomyomas (LM) for immunoreactivity with a panel of 11 antibodies. All IVLs and LMs reacted with antibodies to alpha-smooth muscle actin (alphasm), h caldesmon, vimentin and progesterone receptor (PR). Five of six IVLs and all LMs reacted with desmin. All IVLs were negative for CD-10. Only one LM exhibited focal CD-10 positivity. Three of six IVLs and nine of 12 LMs showed estrogen receptor expression. All IVLs and LMs showed immunnegativity with MIB-1 and inhibin. There were not any significant differences between immunoreactivity patterns of IVL and LM for asm, desmin, h caldesmon, CD-10, MIB-1 and PR. We conclude that, although they appear to be useful markers in differentiating IVL from ESS and LMS, a larger study also including ESS and LMS would be necessary to confirm their validity.

The value of epithelial membrane antigen overexpression in hyperplastic and malignant endometrium and its relationship with steroid hormone receptor expression.

The aim of this study was to evaluate the value of epithelial membrane antigen overexpression (EMA OE) in benign, hyperplastic and neoplastic endometrium and to analyze its association with estrogen and progesterone receptors (ER, PR) immunohistochemistry, tumor grade and myometrial invasion in patients with endometrial carcinoma (EC). The OE of EMA was analysed immunohistochemically in nine patients with benign endometrium (BE), in 18 patients with atypical complex endometrial hyperplasia (ACH) and in 29 patients with EC. EMA OE was present in 13 of 29 patients (44.8%) with EC, in two of 18 patients (11.1 %) with ACH, and in none of nine patients with BE (p < 0.05). EMA OE of endometrial carcinoma was statistically correlated with the International Federation of Gynecology and Obstetrics (FIGO) grade (G1 vs G2 and G3, p < 0.05) and depth of myometrial invasion (< 1/2 vs > 1/2, p < 0.05). EMA OE was significantly associated with PR negativity (p < 0.001). However it did not show any association with ER immunohistochemistry (p = 0.14). PR immunohistochemistry had significant correlations with FIGO grade (p < 0.001) and depth of myometrial invasion (p < 0.05) but ER loss showed a nearly significant association only with advanced FIGO grade (p = 0.054). In conclusion, EMA shows increased expression as the lesion progresses to malignancy and can also aid discrimination between hyperplastic and neoplastic states. The correlation of imunohistochemical findings with tumor grade and myometrial invasion could help in predicting behavior of the tumor and planning treatment in patients with endometrial carcinoma.

Diagnostic problems on frozen section examination of myometrial invasion in patients with endometrial carcinoma with special emphasis on the pitfalls of deep adenomyosis with carcinomatous involvement.

Frozen-section and paraffin section diagnoses were compared in 55 patients with Stage I endometrial adenocarcinoma. In 44 patients (80%), a corresponding depth of myometrial invasion and in 54 (98%) patients the same tumor grade were found. Regarding the depth of myometrial invasion and histologic grade, sensitivity, specificity, positive and negative predictive values were 70%, 86%, 73%, 83% and 92%, 100%, 100%, 94%, respectively. Concerning myometrial invasion 9% false-positivity and 10% false-negativity rates were noted. The histopathologic characteristics of false-positive and false-negative patients are emphasized because carcinomatous involvement of deeply situated adenomyosis and advanced grade tumors are the main diagnostic pitfalls. It is important for pathologists to be able to identify carcinomatous involvement of adenomyosis and adjacent foci of minimal myometrial invasion during frozen-section examination which can prevent aggressive surgery.
