ÖzBu çalışmanın amacı ratlarda medulla spinalis'in torakal bölümünün substantia alba ve substantia grisea ile tüm dokunun hacim değerlerini stereolojik yöntem ile hesaplamaktır. Çalışmamızda materyal olarak 1 ve 5 aylık olmak üzere iki farklı yaş grubundan altışar adet erkek Wistar Albino ırkı ratlar kullanıldı. Van Yüzüncü Yıl Üniversitesi Tıp Fakültesi Deney Hayvanları Yetiştirme ve Araştırma Merkezi'nden farklı zaman dilimlerinde herhangi bir hastalığa ya da sebebe bağlı olmadan kendiliğinden ölen ratlar % 10'luk formaldehitte bir hafta bekletilerek fikse edildi. Daha sonra ratlar diseke edilerek medulla spinalis'leri ortaya çıkarıldı. Çalışmada 1 ve 5 aylık ratların medulla spinalis'lerinin torakal bölümlerinden segmentler elde edildi. Kesitler alınırken ilk 15 kesit arasından rastgele bir tanesi seçildi. Onu takip eden her 50.kesit sistematik rasgele örnekleme yöntemiyle belirlendi. Böylelikle bir hayvanın medulla spinalis'inin torakal segmentinden 5µm kalınlığında 12 adet kesit alındı. Bu kesitler hematoksilen eozin boyama tekniği ile boyanarak mikroskop altında fotoğraflandı. Cavalieri Prensibi ile Shtereom 1.5 programı kullanılarak noktalı alan cetveli sayesinde medulla spinalis'in torakal bölümünün her bir segmentinde tüm dokunun, substantia alba ve substantia grisea kısımlarının hacim yoğunlukları hesaplandı. Ayrıca araştırmada torakal segmentin tüm hacminin, substantia alba ve substantia grisea hacim değerleri ve bu hacim değerlerinin birbirlerine oranları hesaplanarak değerlendirildi.

“…While the majority of ingested foreign bodies pass through the gastrointestinal system naturally, 10-20% of cases may require rigid or fiberoptic esophagoscopy, and less than 1% may necessitate surgical intervention. 1,2 The majority of foreign-body ingestions, approximately 80%, occur in infants, toddlers, and children, with the highest frequency observed between 6 months and 3 years. Unlike in adults, over 90% of these cases in children are accidental.…”

Objective: To determine the frequencies of different esophageal foreign bodies ingested by children presenting to Ayub Teaching Hospital Abbottabad. Study Design: Cross-sectional study. Setting: Department of Otorhinolaryngology, Ayub Teaching Hospital Abbottabad. Period: 2nd July 2020 to 31st December 2022. Material & Methods: Following the application of inclusion and exclusion criteria, a total of 168 patients, aged between 6 months and 11 years, presenting with suspected esophageal foreign bodies, were included in the study after obtaining written consent. Socio-demographic information, clinical history, and symptoms were carefully recorded. Diagnostic procedures included neck X-rays, extended to the chest, and abdominal X-rays as necessary. Rigid esophagoscopy, performed under general anesthesia, was utilized to confirm and remove foreign bodies. Subsequently, the nature and type of the extracted foreign bodies were identified and documented using a standardized pro forma. Results: The mean age of the patients was 5.63 ± 3.097, ranging from 1 to 11 years. Regarding the gender distribution, 105 (62.5%) were male, and 63 (37.5%) were female. When considering the types of foreign bodies, 129 (76.8%) presented with coins, 12 (7.1%) with metallic objects, 7 (4.2%) with battery cells, and 9 (5.4%) with fruit seeds. Additionally, there were a few cases of chicken bones, fish bones, and safety pins, accounting for 9 (5.4%) in the category of other foreign bodies. Conclusion: This study underscores the frequent occurrence of esophageal foreign body ingestion in young children, particularly males under the age of 5, with coins identified as the predominant culprits.

Esophageal obstruction represents an endoscopic emergency owing to the high mortality rate associated with complications, including perforation and airway compromise. While typically caused by food or foreign body ingestion, esophageal clot represents a rare etiology of obstruction. We present a case of esophageal obstruction in the context of an anastomotic stricture and chronic anticoagulation for atrial fibrillation caused by clot formation due to oral hemorrhage after dental extractions. Clot retrieval was accomplished via endoscopic suction, and balloon dilation of the anastomotic stricture was performed to prevent recurrence. Our case illustrates the importance of considering oral hemorrhage, therapeutic anticoagulation, and esophageal strictures as risk factors for esophageal obstruction due to clot formation in order to make a timely diagnosis and treatment of this potential endoscopic emergency.
