Dalaman tarım işletmesinde yetiştirilen siyah-alacalarda buzağılama mevsiminin süt verimine etkisi

Data of 866 lactations collected from 251 cows raised at Dalaman State Farm in Mugla province between 1989 and 1996 were analyzed. Two calving seasons were determined on data set based on average monthly air temperature. These are the first calving season (November 1 - April 30 ) which is within the comfort zone for cows, and the second calving season (May 1 - October 31 ). Milk yield, calving year, lactation number and calving season were evaluated. The effect of lactation number (p<0.01), calving year (p<0.01) and, calving season (p<0.01) on 305-d milk yield were found statistically significant. The least-square means and standard errors of milk yield for the first and the second calving season were 7493.54±70.29 kg and 7180.63±81.08 kg, respectively.Mugla Ili Dalaman Tarım Isletmesinde 1989 1996 yılları arasında yetistirilen 251 hayvana iliskin toplam 866 laktasyon verileri toplanarak degerlendirilmistir.Aylık ortalama hava sıcaklıkları dikkate alınarak iki buzagılama mevsimi olusturulmustur. Bunlar, konfor sınırları içerisinde olan 1. buzagılama mevsimi (01 Kasım 30 Nisan) ve 2. buzagılama (01 Mayıs 31 Ekim) mevsimidir. Süt verimleri, buzagılama yılı, laktasyon sırası ve buzagılama mevsimi degerlendirilmistir. Yapılan degerlendirmede 305 günlük süt verimine laktasyon sırası (p<0.01), buzagılama yılı (p<0.01) ve buzagılama mevsiminin etkisi (p<0.01) önemli bulunmustur.

Successful management of aggressive fibromatosis of the neck using wide surgical excision: a case report

<p>Abstract</p> <p>Introduction</p> <p>Aggressive fibromatosis is a benign tumor, thought to arise from deep musculoaponeurotic structures, rarely found in the head or neck. However, when it does occur in the head and neck region, it tends to be more aggressive and associated with significant morbidity, which may be attributed to the vital vascular, neurological or anatomical structures in close proximity.</p> <p>Case presentation</p> <p>We report the case of a 39-year-old Pakistani man who presented with a two-month history of a lump on the right side of his neck. The mass was excised and histopathological analysis revealed a case of aggressive fibromatosis.</p> <p>Conclusion</p> <p>Due to the rarity of the condition no guidelines are available on the indications and extent of each modality. Due to its aggressive behavior and tendency to invade local structures and recur, a multi-modality management strategy is usually employed. On the basis of this case, we suggest that aggressive surgery is a viable management option and may be successfully used as a single modality treatment.</p

Epithelioid sarcoma in the thoracic spine

Epithelioid sarcoma is a rare and highly malignant soft tissue tumor that is commonly found in the extremities and rarely in the trunk area. This malignant tumor often mimics granuloma or nodular fasciitis, which causes a delay in establishing the diagnosis. This type of cancer has a high recurrence rate. Surgical treatment requires wide radical resection. The objective of this case report is to highlight the unique location of a rare neoplasm and to illustrate the relentless course of epithelioid sarcoma despite initial radical resection. A 14-year-old boy was admitted to our facility with a soft tissue mass on the right lower thoracic spine. The large tumor mass had deeply penetrated into the muscles, infiltrated the neuroforamen of T9–T10 level, and compressed the dural sac. Immunohistological study of the biopsy was highly consistent with an epithelioid sarcoma. Wide excision of the mass, laminectomy and spine fusion with instrumentation was performed. The patient received chemotherapy and irradiation. The first recurrence of the neoplasm was seen as a contralateral metastasis 21 months after the resection. On the last follow-up, 3 years postoperatively, the patient was in a good general condition. However, further progression of the sarcoma had to be recognized. Our case encompasses multiple features that represent negative prognostic factors. Initial wide excision of the neoplasm and adjuvant therapy including chemotherapy and irradiation seem to slow down the relentless course of epithelioid sarcoma in the trunk

Solid variant of aneurysmal bone cyst of the heel: a case report

<p>Abstract</p> <p>Introduction</p> <p>An aneurysmal bone cyst is a benign but often rapidly expanding osteolytic multi-cystic osseous lesion that occurs as a primary, secondary, intra-osseous, extra-osseous, solid or conventional lesion. It frequently coexists with other benign and malignant bone tumors. Although it is considered to be reactive in nature, there is evidence that some aneurysmal bone cysts are true neoplasms. The solid variant of aneurysmal bone cyst is a rare subtype of aneurysmal bone cyst with a preponderance of solid to cystic elements. Such a case affecting the heel, an unusual site, is reported.</p> <p>Case presentation</p> <p>A 26-year-old Caucasian man presented with pain and swelling in his left lower extremity. A plain radiograph demonstrated an intra-osseous, solitary, eccentric mass in the front portion of the left heel. Computed tomography and magnetic resonance imaging scans showed that the lesion appeared to be sub-cortical, solid with a small cystic portion without the characteristic fluid-fluid level detection but with distinct internal septation. Bone images containing fluid-fluid levels are usually produced by aneurysmal bone cysts. The fluid-fluid level due to bleeding within the tumor followed by layering of the blood components based density differences, but it was not seen in our case. An intra-lesional excision was performed. Microscopic examination revealed fibrous septa with spindle cell fibroblastic proliferation, capillaries and extensive areas of mature osteoid and reactive woven bone formation rimmed by osteoblasts. The spindle cells had low mitotic activity, and atypical forms were absent. The histological features of the lesion were consistent with the solid variant of an aneurysmal bone cyst.</p> <p>Conclusion</p> <p>Solid aneurysmal bone cysts have been of great interest to pathologists because they may be mistaken for malignant tumors, mainly in cases of giant cell tumors or osteosarcomas, because of cellularity and variable mitotic activity. It is rather obvious that the correlation of clinical, radiological and histological findings is necessary for the differential diagnosis. The eventual diagnosis is based on microscopic evidence and is made when a predominance of solid to cystic elements is found. The present case is of great interest because of the nature of the neoplasm and the extremely unusual location in which it developed. Pathologists must be alert for such a diagnosis.</p
