Concussion occurs with some frequency in a variety of sports. Any trauma to the brain can also result in temporary or chronic olfactory dysfunction. The relationship between sports concussion and olfactory dysfunction is not well studied, nor do we know whether only more severe injuries result in smell impairments. Three sports players who had previously experienced either a moderate or severe concussion were compared to matched controls. Only the player with a previous severe concussion had a current olfactory impairment. We tentatively suggest that the distinction between moderate and severe concussion may represent a possible cut-off between the presence and absence of olfactory impairment in sports players.

Background: To determine the spectrum of shoulder pathologies suffered by surfers. Methods: Prospective descriptive study. Surfers with shoulder injuries who were referred to a sub-speciality orthopaedic shoulder private practice situated on the Northern beaches of Sydney (Australia) were recruited over a three-year period. Results: 42 shoulders in 37 subjects were included-12 acute injuries (29.3%), 9 acute on chronic (22%) and 20 chronic injuries. Average age 48 years (range 20-72 years). Seventeen subjects (46%) had manual occupations and 20 subjects (54%) had office-based occupations. Spectrum of pathologies included rotator cuff tendon tears, long head of biceps tendon pathology, labral tears, acromioclavicular and glenohumeral joint osteoarthritis. Discussion: There is a wide spectrum of acute and chronic shoulder injuries sustained by surfers. The most common presentation was for chronic pathology. The average age of 48 suggests that age may play a role in attritional/degenerative change and therefore an increased likelihood of injury.

In order to suggest new pathogenetic hypothesis in some heart disease we think is interesting to observe some biomedical literature: Can we think some endogenus toxicologic movens in some heart pathologies?

A malignant tumor has the capacity to grow rapidly and to metastasize to the other parts of the body. Ovary has been a common organ for secondaries caused by hematological spread of the tumor and exhibits the same histopathology as that of the primary tumor. Very rarely, it has been found that the patients suffer from two or more histologically distinct, simultaneously detected malignancies, which are called as synchronous tumors or multiple primaries [1]. These multiple primaries can have an impact on cancer treatment (e.g., surgery) and affect the overall prognosis of the patient. Although there is no consensus on the definition of synchronous cancer, commonly two or more primary tumors that occur in a patient closely with respect to the time interval are termed as synchronous tumors [2]. Simultaneous diagnosis of gall bladder carcinoma with ovarian carcinoma with distinct histopathology is rare. A very few cases have been reported so far in literature. We discuss here a rare case that presented with synchronous tumor of gall bladder and the ovary.

Dry eye or keratoconjunctivitis sicca, is commonly seen in the dog. Veterinary ophthalmologists diagnose this aqueous tear deficiency using the Schirmer tear test (STT), but this measures tear production and does not indicate ocular surface pathology. The vital dye Rose Bengal is commonly used in the diagnosis of dry eye in human patients but until now has not been reported in veterinary patients. Here we corelate the degree of Rose Bengal staining with the STT value and find a reasonable association between dye staining of the ocular surface and tear production, although clearly other factors are also important in the genesis of ocular surface damage in dry eye.

Breast cancer is a complex disease and one of the main causes of cancer-related mortality in women worldwide. In case of approximately 15% of all breast cancers, three markers i.e. estrogen receptors (ER), progesterone receptors (PR) and human epidermal growth factor receptors-2 (HER2) are not expressed, and is commonly termed as triple-negative breast cancer (TNBC). Particularly, TNBC is associated with a higher percentage of breast cancer related mortality, which is often aggressive and most frequently found with a BRCA1 mutation or increased basal marker expression. However, due to the limitations of chemotherapy and radiation based treatment; the current challenge is to establish a new strategy of diagnosis and treatment of TNBC. The deregulation of a number of microRNAs (miRNAs) in breast cancer has been widely reported. Therefore, this review is directed towards enhancing our understanding of the involvement of various miRNAs in the pathology of TNBC, their upregulations and downregulations and the effects on various factors. From recent studies a number of miRNAs are found to be related with TNBC, which have great potential to be used as a biomarker to determine the disease prognosis and predict the fate of disease. Again miRNA can be targeted to be applied as a therapeutic to provide a great benefit to the patients of TNBC by finding a new, safe, and effective treatment strategy.

The indications for impacted third molar extraction include the prevention of dental reabsorption on the adjacent tooth. Resorption can be classified as physiological (when deciduous teeth are exfoliated) or pathological (when caused by injury or irritation to the periodontal ligament). Many causes can trigger external root resorption (ERR), the most common cause of which is orthodontic forces. The most common cases of ERR involve impacted third molars which, due to the lack of space for their eruption, generate a greater chance of ERR on the distal portion of the second molar. This pathology is becoming progressively more frequent in clinical dental care. Periapical and panoramic radiographs are used to aid in diagnosis, as is cone beam computed tomography. In cone beam computed tomography scans, radiolucent areas with irregular gaps are detected; these gaps represent a significant loss of dental material. The objectives of this article were to report a case of second molar resorption triggered by an impacted third molar and to perform a review of the literature on the causes of external root resorption. Ideally, this information will aid dental clinicians (and orthodontists in particular) in understanding the features of this pathology so that they may recommend preventive third molar extraction when necessary.

Statement of the problem: Anterior tooth fracture, as a result of traumatic injuries, frequently occurs in dentistry. This leads to necrosis of pulp and periapical pathology. The goal of endodontic and restorative dentistry is to retain natural teeth with maximum function and pleasing esthetics. Purpose of the study: This study aimed at proper reconstruction of extensively damaged teeth through the procedure known as “Biological Restoration.” Materials and methods: Biological post obtained through natural, extracted teeth from another individual represents a low-cost option and alternative technique for the morphofunctional recovery of damaged anterior teeth that provides highly functional and esthetic outcomes. Conclusions: This case report refers to the esthetics and functional recovery of mandibular left lateral incisor after non-surgical healing of periradicular lesion.

The Office hysteroscopy (OH) is a important procedure to make diagnosis and sometimes, treatment, of intrauterine pathology, without getting the patient to Operating Room. Its advantages are very well known: less costs, fast diagnosis, see and treat and several others. It's mainly difficulty is the discomfort during the procedure. To stimule to grow the number of gynecologist to leave OR and to go to office hysteroscopy, we propose thirteen steps for office hysteroscopy with minimal discomfort.

An investigation into the pathological lesions of Cypermethrin on the testes, accessory sexual and pituitary glands of Yankasa rams was carried out. Sixteen Yankasa rams aged 18 - 30 months and weighing between 21.5 - 46.5kg were used. The 16 rams were divided equally into two groups (A and B) A served as the treatment group while B served as the control. Group (A) were given Cypermethrin (3%) at the dose rate of 3mg/kg (0.1ml/kg) body weight, topically. Group (B) rams were given distilled water at the same dose rate and route. These treatments were repeated every two weeks for a period of 12 weeks. The rams were sacrificed at the end of 12 weeks and the following organs (testes, pituitary, vesicular and prostate glands), were collected and weighed, gross pathological lesions were observed and photographs were taken. The samples were kept for histopathology. Results showed that there were no gross pathological lesions found on the testes, pituitary, prostate glands and the seminal vesicles of both groups. The mean weight of the pituitary gland, the prostate glands and the seminal vesicles of the treated and control groups were statistically not significant (P>0.05). No histologic lesions were found on them. The mean testicular weights of the treated (143.81±7.71g) and the control (130.43±0.63g) were significantly different (P<0.05). There was a reduced number of spermatozoa in the lumen of the seminiferous tubules of the treated group. It was concluded that Cypermethrin reduced spermatozoa in the lumen of the seminiferous tubules.

Medical postgraduate trainees are given increasing levels of responsibility during training in the apprenticeship-model of training [1-3]. Responsibility is said to be a key driver of deep learning and understanding [4-7]. Trainees with greater levels of responsibility for decision making have higher levels of motivation to learn compared with trainees who self-assess as having less autonomy [5]. The Royal College of Pathologists (RCPath) indicate that ‘graded responsibility’ is part of training histopathologists and provided a framework for implementation with increasingly complex specimens suitable for reporting by more senior trainees [8,9]. 

Background: Leiomyoma itself is not a rare disease, but it is rarely found intravascularly. Case presentation: A 54-year old female sought medical help after noticing her leg being swelling. A diagnosis of deep vein thrombosis (DVT) was made and antithrombotic treatment was given after her initial imaging exam. Several days later, a contrast CT and sequential pathology revealed the real diagnosis was intravascular leiomyoma. The patient was discharged after a successful surgery. Conclusion: Intravascular leiomyoma should not be confused with DVT.

Background: The aim of the study was to evaluate radiographic features of systemic sclerosis-associated interstitial lung disease. Patients and methods: 116 patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) from 2010 to 2019 comprised our retrospective study. All patients were subject to high resolution computed tomography (HRCT). ILD patterns were classified into 7 patterns as IIPs and analyzed with pathology. We chose two staging method and two semi-quantitative score methods to evaluate the HRCT performance and analyzed with pulmonary function tests. Results: Ground-glass opacities were the most common presentation on HRCT, followed by interlobular septal thickening, reticular opacities, intralobular interstitial thickening; honeycombing, traction bronchiectasis and nodules can also be observed. The most common pattern of SSc-ILD was nonspecific interstitial pneumonia (NSIP), secondly was UIP. There was no difference in ILD pattern between HRCT and pathology, and revealed a high congruence. The four HRCT evaluating methods presented in this study all had significant relationships with PETs. Conclusion: The most common pattern of SSc-ILD was nonspecific interstitial pneumonia (NSIP). The ILD patterns of HRCT coincide very well with histology, and will replace pathology as the gold standard for diagnosis and evaluation of SSc-ILD.

In 1874 J.M. Charcot was the first to describe ALS amyotrophic lateral sclerosis, a disease with an high non response therapy rate also to the actual therapy. ALS is not clearly associate to only single etio-patogenetic movens but many process seem involved. Also the strange geographic diffusion of different forms contribute to a complex syndromic pathology. The introducing of new theories and approach can help to find more efficacy therapeutic strategies. In this work the different neuronal damage movens and new therapeutic strategies are analyzed to produce a Unic global response to the pathologic process useful in next clinical application. Genetic factors must be considered also added to environmental movens but also to the endogenous microenvironment of motoneuron involved. A toxicological-biochemical-imunological approach can be useful tool to find new therapeutic strategies. Or to improve local availability of pharmacological molecules.

In various patients conditions involved in lower urinary tract disease LUT (like overactive bladder, bladder neck sclerosis, dis –synergy (with our synenrgic contraction between bladder detrusor and bladder neck, BPH, recurrent cysytitis, interstitial cystitis, chronic prostatitis, uretral stenosys, loss of sfinteric coordination. Prostatic cancer, anatomic abnormalities and other the receptor status play relevant role to reduce effect of vicious clycle that can be responsible in progression of the pathologic process. In this work the complex receptorial status is analyzed to verify new therapeutic strategies. Starting from the observation that various irritant substanties produce irritant stimulus in Prostatic Patients or in bladder neck condition is interesting to deep understand the etio-patogenesys and Functional results. In Various prostatic, bladder neck or ureteral condition a reduced urinary fluss can produce infectious. Conditions like acute or chronic prostatitis. Irritants sustanties in diet (in example etilic alcohol drink, hot spices, crud meats, carbonate drinks, caffeine and other) can produce Painful stimulus in innervations of vecical trigonous, bladder neck and prostatic urethra. The same recurrent cystitis and Bph contribute in a complex situation. This stimulus produce ipertonus of bladder muscle involved in the expulsion of urine. The event related inflamation and edema (bladder, prostatic uretra, trigonus) contribute to the global effect. So conditions like bladder neck sclerosys IPB, recurrent prostatitis and cistitys in acts in a vicious circle. (Also immunomediated: Bph and cronic prostatitis with linfocite infiltration and tissue remodeling). The ormonal status check the systems (see 5-ARI efficacy in Bph). Simpatic, parasimpatic and other system are deeply involved. Also behavioral habits or diet can influence in example urinary flux in a complex system like LUT. (Bladder and prostatic irritants that can produce edema and acute inflamation). Other behavior habits are deeply involved as too much sedentary, water intake, coffee, pee modality and also psychological profile and stressing conditions. Some disease like diabetes produce high consequences in all this systems due to Bladder modification, oxidative stress, osmotic movens, and increase susceptibility of urinary infections. This article are verified this kind of movens that contribute in physio -pathology of some low urinary tract conditions. The anatomic abnormalities produces, obviously, physiological disfuntions. Recurrent urinary tract infections, inadequate antimicrobial therapy: Profile of resistance, duration of therapy, kind of antimicrobials, posology, Pk. Kinetics, associations, compliance, biofilms, micro calcifications (recurrent chronic prostatitis) contribute to a progression of the condition.

Nonsurgical fertility control is increasingly advocated as more cost-effective than surgical sterilization to manage stray animal populations in a different part of the world. An experimental study was conducted from December 2018 to April 2019 at Mekelle University to evaluate the effect of single bilateral intratesticular injection of cetrimide 2% in adult albino mice. A total of 20 clinically healthy albino mice selected based on their age and sex and were divided randomly into five groups and evaluation was conducted for 30 days after intratesticular injection of cetrimide solution 2% at the dose rate of 5, 10, 15 and 20 mg per testis and for control 0.1 mL normal saline per testis per 100 g body weight were given. All albino mice were evaluated for 30 days at a fixed interval. Change in body weight, scrotal width, sexual behavior, and fertility performance was also assessed. On day 30, all albino mice were sacrificed for histopathological study. Means  ±  Standard deviation of the mean, one-way, and a mixed model ANOVA (for repeated measures) was used to summarize the data, determine the effects of group and time on bodyweight and scrotal width. The significant increase in body weight (p - 0.001) and significant reduction of scrotal width (p - 0.001) were noted in all cetrimide treated in comparison to control groups. In addition, there was a significant (p < 0.05) reduction of scrotal width in albino mice after intratesticular injection of cetrimide on day 1, 10, 15, 20, 25, and 30 with respect to their experimental groups. Testicular histology revealed that there were multinucleated giant cells in seminiferous tubules, derangement of tubular architecture along with infiltration of leucocytes and appearance of fibrous tissue were seen on testicular sections at a dose rate of 15 and 20 mg. Similarly, a significant change in the sexual behavior of the treated males and no pregnancy was detected on female albino mice after 21 days post-coital at 10, 15, or 20 mg cetrimide-treated males. In conclusion, a single bilateral intratesticular injection of cetrimide 2% at a dose of 15 and 20 mg might provide an effective way of sterilization and may be considered as an alternative to surgical castration in male animals. Besides, further assessment should be done in the future to identify the mechanism of infertility.

Uterine sections from 6 patients with incidental nodal lymphangioleiomyomatosis (LAM) were examined for LAM lesions by screening these sections with cathepsin K immunohistochemistry (IHC) stains. The hysterectomy specimens were all concurrent with the lymph node dissections in which the nodal LAM was discovered. In 4 of 6 patients microscopic lesions of pre-LAM were identified and confirmed by IHC staining for HMB-45 and beta-catenin. All lesions were grossly inapparent and also inapparent by routine hematoxylin and eosin stains. Three variants of pre-LAM lesions were identified. None of the pre-LAM lesions had an associated lymphatic proliferation. It is proposed that these pre-LAM lesions gave rise to the incidental nodal LAM lesions. Furthermore, it is suggested that the absence of an associated lymphatic proliferation associated with these lesions may be a factor in the attenuated potential for spread and the only rare association of these nodal lesions with pulmonary LAM.

Isocitrate dehydrogenase (IDH) mutations are a common event in secondary glioblastoma multiforme and lower-grade adult infiltrative astrocytomas and independently confer a better prognosis [1,2]. These are highly conserved mutations during glioma progression and thus also a useful diagnostic marker amenable to modern molecular sequencing methods. These mutations can even be detected in sites distant from the primary tumour. We use an illustrative case of a patient with radiologically suspected recurrent astrocytoma and negative histology, but positive IDH-mutated tumour DNA detected within CSF. Our results demonstrated the usefulness of liquid biopsy for recurrent glioma within the context of equivocal or negative histopathological results, whilst also showing the ability to detect a de-novo IDH-2 mutation not present in the previous resection. Building on this ‘proof-of-concept’ result, we also take the opportunity to briefly review the current literature describing the various liquid biopsy substrates available to diagnose infiltrative gliomas, namely the study of circulating tumour DNA, circulating tumour cells, and extracellular vesicles. We outline the current challenges and prospects of liquid biopsies in these tumours and suggest that more studies are required to overcome these challenges and harness the potential benefits of liquid biopsies in guiding our management of gliomas

Micronodular thymoma is a rare subtype of thymoma with less than 20 cases published in the English literature. These tumours have been reported with thymoma or thymic cyst. The authors describe a new case of micronodular thymoma in a 68-year-old-patient which is well documented and particular by its cystic degeneration which hasn’t been described yet. Micronodular thymoma is a rare variant of thymoma with a challenging diagnosis. Clinicians must be aware of this entity in order not to confuse it with a thymic cyst.

43-year-old lady presented with incidentally discovered liver lesions while she was being managed for her complaints of menorrhagia. CT and MRI showed hepatomegaly with multiple lesions in both lobes of the liver with vascular element in the background of diffuse fatty infiltration. Patient underwent laparoscopic core biopsy. Histopathology showed extensive steatosis, intracytoplasmic giant mitochondria and absence of portal tracts, features highly suggestive of hepatic adenomatosis. IHC staining showed membranous and cytoplasmic positivity in hepatocytes for B-catenin consistent with multiple hepatic adenomatosis. Hepatic adenomatosis is a new clinical entity in the hepatological practice characterized by the presence of 10 or more nodules in the liver known for its major complication of bleeding. Hepatic adenomatosis is managed by regular imaging and resection of large (> 5cm) superficial and painful adenomas along with liver function tests and tumor markers to rule out malignant transformation. However, the potential cure being the liver transplantation.
