Effects of an aerobic training program on liver functions in male athletes: a randomized controlled trial.

The optimal functioning of the liver is essential for athletic performance. It is necessary to maintain the liver's enzymes at an optimal level so that liver cells can be protected from inflammation or damage. This study investigated the effects of a 12-week aerobic exercise program on the liver function of adult athletes. A pretest-posttest experimental design was used. A total of thirty healthy male athletes (football players) aged 21 to 24 years were recruited for this study and randomly and equally divided into the experimental group (EG) and control group (CG). The CG did not participate in any special activities. The EG performed an aerobic training program consisting of several exercises for 12 weeks. Evaluation of all participants in both groups was carried out before and after the intervention by measuring the blood levels of Alkaline phosphate, AST/SGOT, ALT/SGPT, Bilirubin Total/indirect/direct, Albumin, Globulin, and Total protein using the standard methods by collecting blood samples. There was a significant decrease (p < 0.05) in Bilirubin and globulin levels in the EG after 12 weeks of aerobic training sessions. However, there was no significant difference in alkaline phosphate, AST/SGOT, ALT/SGPT Total protein, and Albumin (p > 0.05) between both groups post-treatment. The 12 weeks of aerobic training used in the study can potentially improve the liver function of adult athletes.

Use of GaAlAs Diode Laser for Excisional Biopsy of Gingival Giant Cell Fibroma: A Case Report of a Rare Lesion.

Giant cell fibroma (GCF) is a relatively rare lesion in the oral cavity. Despite having unique microscopic features, it can be easily misdiagnosed clinically as any common hyperplastic lesion. This report presents a case of a 21-year old male with a lesion involving the papilla between the mandibular central incisors. The lesion was excised completely under topical anesthesia using a 980 nm diode laser. On histopathological examination of the excised tissue, no thermal damage or any other alteration was observed, while the features were suggestive of GCF. Healing of the gingiva was uneventful and without any signs of recurrence. Apart from the widely known advantages of the diode laser, it also appears to maintain the integrity of biopsy specimens, if used with appropriate settings. This advantage may play a vital role in the biopsy of rare lesions where the diagnosis is entirely based on accurate histopathological examination.

Utility of Cytospin and Cell block Technology in Evaluation of Body Fluids and Urine Samples: A Comparative Study.

BACKGROUND: Cytologic examination of body fluids commonly involves the use of direct or sediment smears, cytocentrifuge preparations, membrane filter preparations, or cell block sections. Cytospin and cell block techniques are extremely useful in improving cell yield of thin serous effusions and urine samples, and ensure high diagnostic efficacy. MATERIALS AND METHODS: We studied cytospin preparations and cell block sections prepared from 180 samples of body fluids and urine samples to compare the relative efficiency of cell retrieval, preservation of cell morphology, ease of application of special stains, and diagnostic efficacy. Samples were collected and processed to prepare cytospin smears and cell block sections. RESULTS: We observed that overall, cell yield and preservation of individual cell morphology were better in cytospin preparations as compared to cell blocks, while preservation of architectural pattern was better in cell block sections. The number of suspicious cases also decreased on cell block sections, with increased detection of malignancy. It was difficult to prepare cell blocks from urine samples due to low cellularity. CONCLUSIONS: Cytospin technology is a quick, efficient, and cost-effective method of increasing cell yield in hypocellular samples, with better preservation of cell morphology. Cell blocks are better prepared from high cellularity fluids; however, tissue architecture is better studied, with improved rate of diagnosis and decrease in ambiguous results. Numerous sections can be prepared from a small amount of material. Special stains and immunochemical stains can be easily applied to cell blocks. It also provides a source of archival material.

Retiform Hemangioendothelioma of the Gluteal Region: A Case Report.

Retiform hemangioendothelioma is a locally aggressive, rarely metastasizing, low-grade angiosarcoma characterized by intercommunicating vascular channels lined by hobnail or cuboidal endothelial cells, flanked by lymphocyte and hyaline sclerosis. Neoplastic endothelial cells usually express von Willebrand factor, CD31 and CD34, while the lymphocytic infiltrate shows a mixture of CD3+, T and CD20+ B cells. The authors describe a case of a 76-year-old female who presented with a soft, painless, ill-defined mass measuring 9 cm in her right gluteal region for the past 15 years, clinically suggestive of a lipoma. There was no regional lymphadenopathy. The mass was resected and sent for histopathological examination. The slow-growing lesion and the typical histomorphology led to the diagnosis of retiform hemangioendothelioma. The diagnosis was confirmed by immunohistochemistry using CD34 antibody, which strongly stained the endothelial cells. The patient was followed up for 6 months after the surgery and no recurrence was noted.

Disseminated cryptococcosis in an immunocompetent child.

Cryptococcus is a ubiquitous fungus and is known for causing meningitis and cutaneous infections in immunocompromised individuals. Disseminated cryptococcal infection is very rare and almost always found to occur in immunocompromised individuals especially in persons infected with HIV. This is particularly attributed to its capsulated spores. But there are few reported cases in which it has been found to cause disseminated infections even in immunocompetent individuals. We report a similar case of disseminated cryptococcal infection in an immunocompetent host. Early detection and treatment of disseminated cryptococcosis is essential to reduce morbidity and for better outcome.

Ovarian Yolk Sac Tumor with Granulomatous Reaction Resembling Tuberculosis - A Unique Presentation.

Yolk sac tumors (endodermal sinus tumors) are an important subgroup of germ cell tumors of the ovary. They are seen in young females and are highly aggressive, but respond well to treatment. Although different morphological patterns can be seen on light microscopy, granulomatous reaction and giant cells are a very rare occurrence. We report the case of a young female with ovarian yolk-sac tumor in which a widespread granulomatous reaction was seen, causing a diagnostic dilemma.

Spindle-cell ameloblastic carcinoma of the maxilla with adenoid cystic carcinoma-like areas: A new variant?

Ameloblastic carcinoma is a rare aggressive malignancy of odontogenic epithelial origin. The disease has been reported to afflict people over a wide range of age group without any sex predilection. It is characterized by rapid growth and destruction of overlying bones along with involvement of adjacent soft tissues. The overall prognosis of this cancer is poor despite radical surgery and radiotherapy. Owing to the rarity of this lesion, complete data on the biological behavior and response to different treatment modalities are still lacking. The authors hereby report a case of this uncommon tumor arising from left maxilla in a 60-year-old Indian male. Histopathological examination of the tumor showed foci of spindling intermixed with large areas of tumor cells arranged in cribriform pattern and having luminal eosinophilic material which was reminiscent of adenoid cystic carcinoma. A final diagnosis was achieved after immunohistochemical study. These unusual findings prompted this case report.

Trabecular Variant of Juvenile Aggressive Ossifying Fibroma.

Juvenile aggressive ossifying fibroma (JAOF) is an uncommon benign lesion which is distinctly aggressive in behavior with high tendency for recurrence. It appears in early age and in 79% of patients is diagnosed before 15. It has two histological variants: psammomatoid and trabecular, with the latter being less common with a stronger tendency to recur. In this article, we present a case of trabecular JAOF, in which treatment could not be given despite the availability of all requisites for surgery and good financial status, due to parental indifference and negligence.

Myopericytoma of lip: a rare lesion in an unusual location.

Myopericytoma is a rare benign tumor with perivascular myoid differentiation. It shares histomorpholoic features with the so-called hemangiopericytoma, myofibroma and glomus tumor. We hereby report the case of a 14-year-old boy who presented with a slowly growing, painless, firm mass on upper lip, diagnosed as myopericytoma on the basis of histopathology and immunohistochemistry. To the best of our knowledge, this is only the second such reported case.

Image-guided fine-needle aspiration of retroperitoneal masses: The role of the cytopathologist.

BACKGROUND: Retroperitoneal tumors constitute a difficult diagnostic category as they are not easily accessible. The advent of image-guided fine-needle aspiration (FNA) has resolved this problem significantly. AIMS: We present a short study based on guided aspiration of retroperitoneal tumors, in which we have tried to assess the role of image-guided fine-needle aspiration cytology as a tool for pre-operative diagnosis. MATERIALS AND METHODS: The study was conducted on patients diagnosed with retroperitoneal masses. FNA was performed under image guidance with the help of ultrasonography and/or computed tomography; smears were prepared and meticulously screened according to a fixed protocol. The results were analyzed to determine sensitivity, specificity, and diagnostic efficacy of cytopathological diagnosis using image-guided FNA techniques. RESULTS: We assessed 38 patients with retroperitoneal masses. In all cases, adequate cellular material was obtained. No major complications were encountered. Statistical analysis was carried out in 35 cases; sensitivity, specificity, and diagnostic accuracy were 100% in these cases. CONCLUSION: FNA under image guidance should be considered a first-line diagnostic approach for retroperitoneal and other abdominal tumors, although caution should be exercised in case selection. In areas where advanced tests are not available, the cytotechnologist and cytopathologist have a very important role to play in ensuring accurate diagnoses.

Metastasis to left scapula with unknown primary: Approach to pathological diagnosis.

Bony metastasis is a frequent occurrence in malignancy. However, the clinical presentation and pathological findings may sometimes be more in favor of a primary bone lesion. In such cases, immunochemistry has a very important role to play in reaching a final diagnosis. We present the case of a 35 year male patient who was investigated for a lytic lesion in the left scapula and was finally diagnosed with metastatic adenocarcinoma with the help of immunostaining.

Smear patterns and spectrum of premalignant and malignant cervical epithelial lesions in postmenopausal Indian women: a hospital-based study.

Cervical cancer is one of the leading causes of morbidity and mortality among women but can be prevented through simple cost-effective measures, such as creating awareness, and regular screening with the Pap smear, both in the premenopausal and postmenopausal age group. This study was carried out to study the cervical smear patterns and type of cervical epithelial lesions in a group of postmenopausal Indian females and the relationship with clinical profile of patients. Pap smears were taken from 320 postmenopausal Indian females and meticulously screened. Lesions were classified according to type of postmenopausal pattern. 120 smears showed varying degrees of premalignant and malignant changes, which were classified using the Bethesda system. The findings were correlated with duration of menopause, parity, and duration of sexual activity and significance was derived. Histopathological correlation was conducted in those cases where biopsies were available. It was found that as the age of the patients increased, the incidence of low-grade and high-grade squamous intraepithelial lesions and carcinoma also increased with the relationship being statistically significant. The occurrence of these lesions also showed an association with increasing parity and period of sexual activity. Thus, it can be concluded that it is important to create widespread awareness about the necessity of regular screening, including the postmenopausal period. Conventional cytology or the Pap smear is a cost-effective and efficient method for screening of patients but requires training and experience to minimize errors. It is suitable for developing regions where costlier techniques are not in routine use.

Endometrial adenocarcinoma with osteoclastic giant cells in stroma: a case report and review of literature.

It is rare to find osteoclastic giant cells (OGCs) as a stromal reaction in uterine adenocarcinoma of endometrium. Here, we report a case of a 60-year-old female diagnosed with adenocarcinoma of endometrium. Total hysterectomy with bilateral salpingo-oopherectomy and removal of pelvic lymphnodes was performed. Histologically, the tumour showed adenocarcinoma of the endometrium with mucin secretion. The stroma showed some plump reactive pleomorphic cells, resembling stromal cells, infiltrated uniformly with OGCs and mononuclear cells (MNCs). The epithelial cells of adenocarcinoma stained positive for cytokeratin (CK 7) (CAM 5.2). The osteoclastic giant cells and mononuclear cells stained positive with CD68 and negative with cytokeratin and vimentin. We conclude that the osteoclastic giant cells originated from reactive histiocytes/monocytes as a stromal reaction to malignancy.

Ovarian steroid cell tumour: correlation of histopathology with clinicopathologic features.

Ovarian steroid cell tumours (not otherwise specified) are rare neoplasms of the ovary and are classified under lipid cell tumours. Their diagnosis can be considered as one of exclusion. Histopathologically, the tumour should carefully be evaluated for microscopic features of malignancy, but it is essential for the clinician and the pathologist to remember that in these tumours, pathologically benign histomorphology does not exclude the possibility of clinically malignant behaviour. Our case study focuses on the comparative findings in a postmenopausal female diagnosed with an ovarian steroid tumour (not otherwise specified). A careful correlation between clinical and surgical evaluation and microscopic analysis is necessary, as is a regular followup.

FNAC diagnosis of medullary carcinoma thyroid: A report of three cases with review of literature.

Medullary carcinoma of the thyroid is an unusual neoplasm, which is associated with specific supportive diagnostic markers. Despite this, its cytological diagnosis is often difficult. We report herewith three cases of medullary thyroid carcinoma. The diagnosis was established on fine-needle aspiration cytology. Plasmacytoid cell pattern was observed in two cases and spindle cell pattern in the third case.

Image-guided fine-needle aspiration cytology of ovarian tumors: An assessment of diagnostic efficacy.

BACKGROUND: Image-guided fine-needle aspiration cytology (FNAC) of ovarian lumps is being increasingly used for the successful diagnosis of ovarian tumors, although borderline cases may be difficult to diagnose by this method. AIM: To demonstrate the efficacy of image-guided FNAC in diagnosing ovarian tumors (benign and malignant) and to evaluate the usefulness of cytology as a mode of easy and rapid diagnosis of ovarian lumps. MATERIALS AND METHODS: The study was conducted on 42 female patients. Clinical evaluation and relevant investigations were carried out. Diagnosis was established by FNAC performed under image guidance (ultrasonography/computed tomography). The cytological diagnosis was confirmed by histopathological examination. RESULTS: Cytological diagnosis was rendered on all the 42 ovarian lesions, with a correct diagnosis in 34 cases, resulting in a diagnostic accuracy of 80.9%. Most of the cases with discordant diagnoses were surface epithelial tumors of low malignant potential and required histopathological examination for a final diagnosis. CONCLUSIONS: Image-guided FNAC is an inexpensive, rapid and fairly accurate procedure for the diagnosis of ovarian lesions. It provides a safe alternative to the more expensive, time consuming and cumbersome surgical route to diagnosis.

Small Cell Carcinoma in the Mammary Gland: Primary or Metastatic? A Diagnostic Challenge.

Metastatic tumours to the mammary gland are relatively uncommon as compared to primary breast malignancies. Such lesions can pose diagnostic dilemmas for both the clinician and the pathologist because it is often difficult to categorize the tumour as primary or secondary and to determine the site of origin. We present the case of a thirty year old female who was diagnosed with small cell neuro-endocrine carcinoma in the mammary gland, probably of pulmonary origin. The diagnostic challenges posed by such a case are highlighted.

Modified fine-needle aspiration technique for diagnosis of granulomatous skin lesions with special reference to leprosy and cutaneous tuberculosis.

Skin infections are commonly assessed by slit skin or scrape methods. Fine-needle aspiration biopsy (FNAB) is highly effective especially with blanching of skin to ensure good yield and reduced bleeding. The aim of this study was to assess usefulness of cytology, especially modified FNAB technique, in diagnosis of leprosy and cutaneous tuberculosis and to identify specific cytological characteristics for diagnosis and classification. The study was conducted on 40 patients-25 cases of leprosy and 15 cases of cutaneous tuberculosis. Smears were prepared using modified FNAB technique, slit skin, and scrape methods (depending on type of lesion). Cytological diagnosis was confirmed by histopathology where the Ridley-Jopling system was used to classify cases of leprosy. A similar attempt was made for diagnosis and classification of leprosy on cytology. Diagnoses rendered by both modalities were compared to assess the efficacy of cytological examination. Cytological diagnosis was made in 23 cases of leprosy and 12 cases of cutaneous tuberculosis. The smears showed good cellularity. A broad division into tuberculoid and lepromatous leprosy could be made fairly accurately on cytology. Maximum agreement among clinical, cytological, and histopathological diagnosis was observed in cases of tuberculoid leprosy. Smears of cutaneous tuberculosis were characterized by epithelioid cell granulomas with caseation. Overall accuracy of diagnosis was 92% in leprosy and 80% in tuberculosis. FNAB is an inexpensive and accurate procedure for diagnosis of leprosy and cutaneous tuberculosis. The modified technique yields good results. However, clinical correlation, acid-fast staining, and culture are essential as they provide valuable supportive information.

Cytological diagnosis of multiple myeloma presenting as a jaw swelling.

Multiple myeloma is a systemic B-cell lymphoproliferative disease with varied manifestations. Its diagnosis can therefore pose difficulties for both the clinicians and pathologists. Jaw lesions, though not uncommon, rarely present as the first sign in multiple myeloma. We present here the case of a 45 year-old female who presented with a swelling of the jaw and on subsequent work-up, was diagnosed with multiple myeloma. Recent research regarding this disease has also been highlighted.

Ocular manifestations of cysticercosis: a case report.

Ocular and extraocular cysticercosis is a commonly encountered manifestation of the disease caused by the cysticercus cellulosae. Any region of the eye may be afflicted including the subconjunctival space. We present the case ofa young female who developed a small mass at the medial canthus of the left eye, which was diagnosed as conjunctival cysticercosis subsequent to excision and histopathological examination.
