[ effect of combined training [hip abductor and external rotators strengthening + balance] on pain and performance in the patients with patellofemoral pain syndrome]

Background and Aim: patellofemoral pain syndrome [PFPS] is an orthopedic disorder of the knee joint which results in pain and impairment of performance. The purpose of this study was to investigate the effect of combined exercise [hip abductor and external rotators strengthening + balance] on pain and performance in the patients with PFPS

Materials and Methods: in this semi experimental study, 20 men with PFPS were selected by purposeful sampling and then randomly assigned to two groups, i.e. experimental [n=10] and control [n=10] groups. The experimental group performed a training program which consisted of hip abductor and external rotators strengthening and balance exercises, 3 sessions per week for eighth weeks. Pain and physical performance in the patients were assessed by Visual Analogue Scale [VAS] and WOMAC respectively, before and after exercise. Repeated measures ANOVA was used to analyze the data. P

Results: the results indicated that the changes and interactions of the two variables of pain [F=14/2 and p=0/001] and physical performance [F=60/2 and p=0/001] were significant in the experimental group [P < 0.05] after exercise. The results also showed that the experimental group, had reduced pain and showed a significant improvement in the physical performance [p<0/05], compared to the control group

Conclusion: considering the effectiveness of training in the improvement of performance and reduction of pain, this training protocol can be useful in the physical rehabilitation of PFPs

Relation between actinomycosis and histopathological and clinical features of the palatine tonsils: an Iranian experience

Actinomycosis of the tonsils has been reported in a variable percentage of tonsil specimens by other authors. This study determines the incidence of actinomyces in the palatine tonsil and evaluates the clinical diagnoses and histopathological features of tonsillectomy specimens. In a retrospective study, 204 patients who had undergone tonsillectomy for recurrent tonsillitis [group A] and for sleep apnea without a history of recurrent tonsillitis [group B] were enrolled. The prevalence rate was significantly higher in the adult compared with the pediatric population. The prevalence of tonsillar actinomycetes colonization was higher in patients who had undergone tonsillectomy for recurrent tonsillitis [43.9%] than in patients who had undergone tonsillectomy for obstructive sleep apnea [26.3%]. The prevalence did not differ by sex of patient. Histopathological analysis of resected tonsils did not show active tissue infection. There was a statistically significant relationship between the presence of actinomycosis and age, with a greater occurrence of actinomycosis in adult patients. Although actinomyces colonization is more prevalent in patients with recurrent tonsillitis than sleepdisordered breathing, but the presence of actinomyces does not indicate any active disease

effect of calendula officinalis in therapy of acetic acid induced ulcerative colitis in dog as an animal model

In patients with ulcerative colitis [UC], the repeated cycle of injury and repair of intestinal mucosa has been reported to increase the risk of colon cancer. So, a safe and efficient therapy is required for the treatment and prophylaxis for the disease. This study aims to investigate the efficacy of Calendula officinalis extract in treatment of experimentally induced ulcerative colitis in dog animal model. During fall 2010, 10 out-bred female German dogs [1-2 years old; weighs of 20-25 kg] were enrolled. Ulcerative colitis was induced with 6% acetic acid as enema and method of treatment was retrograde [via enema] too by C. officinalis. Loose stools, diarrhea, gross bleeding and loss of body weight happened after administration of acetic acid and crypt damage, loss of epithelium, infiltration of inflammatory cells and depletion of goblet cells were noticed histologically. C. officinalis could successfully resolve the damages of UC. Treatment with C. officinalis can broaden the current therapy options for UC

clinico-pathologic study of 82 intraoral minor salivary gland tumors

Intraoral minor salivary glands tumors [MSGT] are uncommon, with geographic variations in frequency and distribution. This study analyzed the clinic-pathologic features of these tumors in Shiraz, southern Iran. All of cases histopathologically recorded as epithelial MSGT in Pathology Department of Khalili Hospital from 2002 to 2009 were evaluated with regard to patient's age and gender, tumor location and type, retrospectively. Out of 82 cases of MSGT, 53.7% were benign and 46.3% were malignant. Pleomorphic adenoma and adenoid cystic carcinoma were the most common benign and malignant tumors, respectively. The palate was the most common site of involvement [64.6%]. Male to female ratio was 1:1.27. The mean age of the patients was 35.0 +/- 17.2 years for benign and 48.8 +/- 18.2 years for malignant tumors. MSGTs in the present study represent many characteristics of other studies. However, our patients who were affected by benign tumors were young

Cartilaginous choristoma in palatine tonsil

Choristoma is a tumor-like mass consisting of tissues foreign to the site at which they are located. We report an 18 years old male presenting with persistent tonsillitis. Histological examination demonstrated the unexpected presence of a mature island of hyaline cartilage surrounded by lymphoid hyperplasia

Nevoid basal cell carcinoma [gorlin] syndrome [case report]

A16 year old boy was admitted to the hospital because of a swelling on the left side of mandible .He had multiple small indurated pearly papules on the head and neck with multiple well circumscribed radiolucent cystic space in mandible on panoramic radiography and CT-scan. Histopathologic studies of mandibular cyst and skin lesions revealed the finding in favor of nevoid basal cell carcinoma syndrome [NBCCS]

value of immunohistochemical markers in pleomorphic adenoma and adenoid cystic carcinoma of the salivary gland

In recent years, immunohistochemical markers have provided considerable contribution to salivary gland tumor diagnosis and classification. The aim of this study was to evaluate diagnostic value of various cytokeratin markers and smooth muscle actin [SMA] in differential diagnosis of pleomorphic adenoma [PA] and adenoid cystic carcinoma [ACC]. In this retrospective study, 35 cases of salivary gland tumors composed of 19 PA and 16 ACC were selected and immunohistochemical staining with six cytokeratin markers [CK7, CK8, CK13, CK14, CK17 and CK18] and SMA were performed. The positivity of these markers in both typical and atypical areas of each tumor was compared. Positivity was defined if 10% or more of the cells were immunostained. In the PA group, there was no difference between luminal and stromal expression of CK7, CK8, CK13, CK14, CK17, and CK18 in both typical and atypical areas except SMA that was not expressed in the atypical area. No statistically significant differences were found between the expression of CK7, CK8, CK14 and CK18 in both typical and atypical areas of ACC group, with no expression of SMA in atypical area. It seems that the immunoprofile of the atypical area of both PA and ACC are similar to each other and IHC does not help to differentiate them

Amniotic membrane transplantation for the treatment of pseudomonas keratitis in experimental rabbits

Amniotic membrane transplantation [AMT] has been considered in combination with medical treatment in progressive infective keratitis. The purpose of this study was to evaluate the efficacy of AMT as an adjunctive treatment in the management of experimental pseudomonas keratitis. Cryopreserved AMT was performed on 12 pseudomonas rabbit corneal ulcers. After one week in one group amniotic membrane transplantation combined Poostchi Eye Research Center with topical medical treatment was done [AMT group]. At the end of the second week, the clinical and pathological findings were compared with those obtained from eight corneal ulcers in another group which had only been treated with topical medication [control group]. There was not any significant difference in clinical signs between the two groups at the end of the second week. Corneal perforation was found in three cases of the control group but in none of the cases in the AMT group. Amniotic membranes were melted in four eyes, retracted in three eyes and intact in five eyes. Pathologic examination showed no significant difference in cellular infiltration or density of organism between the two groups. AMT is effective in preventing corneal perforation in the early stage of experimental pseudomonas keratitis

Head and neck squamous cell carcinoma in Southern Iran

Head and neck squamous cell carcinoma [HNSCC] is the sixth most common cancer among men in the developed world. The objective of this study was to document the gender, age, sites of occurrence and histological differentiation of the HNSCC in southern Iran. In a retrospective study from 1992 to 2007, 386 patients with a histological diagnosis of the HNSCC were investigated in departments of pathology of Shiraz Dental School and Khalili Hospital in southern Iran. Among 386 cases, there were 289 male [74.9%] and 97 female [25.1%]. In younger patients, the male to female ratio was lower than that in the older ones. The larynx was the most commonly affected site [44%], followed by the oral cavity [34.7%], skin [7%], oropharynx [3.1%], hypopharynx [2.9%], cervical esophagus [2.3%], other sites [4.2%] and unknown site [1.8%]. 45.6% were well but 8.3% were poorly differentiated for SCC. HNSCC was most common in the larynx and oral cavity with an older aged male preponderance, but male to female ratio was lower in younger patients than older ones

Apocrine hidrocystoma in external auditory canal

The present report describes clinical, radiographic, and pathological features of an external auditory canal giant apocrine hidrocystoma in a 36-year-old Iranian woman. To the best of our knowledge, this tumor has not previously been reported in this area. There was no evidence of local recurrence one year after surgery

Paraganglioma with radiographic dye: an interesting histopatholological finding

Extraadrenal paraganglioma makes up a dispersed neuroendocrine system which extends from the base of the skull down to the pelvic floor. Paraganglioma have been found in particularly every site in which normal paraganglia are known to occur. Herein, we present a typical case of carotid body paraganglioma according to both histological and immunohistochemical findings. The presence of a large ribbon-like amphophilic to basophilic amorphous material which, according to the history of angiography, must result from the precipitation of angiographic dye makes this entity unique and the first to be reported

Charcot-leyden crystals in hodgkin's lymphoma

Herein, we reported on a middle-aged woman presented with painless cervical lymphadenopathy. Past medical history was not significant. Pathologic examination of incisional biopsy show partial effacement of lymph node architecture with many reactive inflammatory cells admixed with Reed-Sternberg cells, many Charcot-Leyden crystals, and noncaseating granu-loma. Immunohistochemical staining was positive for the classic Reed-Sternberg cells for CD15 and CD30 and was negative for CD45 and CD20. All these findings confirmed the diagnosis of Hodgkin's lymphoma. Charcot-Leyden crystals, is considered a morphologic hallmark of eosinophil-related diseases. However, to the best of our knowledge, only one case of Hodgkin's lymphoma has been reported in the world literature who has had Charcot-Leyden crystals
