The incidence of press-through pack (PTP) ingestion has been increasing. In many cases, the ingested PTP is lodged in the esophagus. Here, we report a case of endoscopic removal of a PTP from the anal canal. An 89-year-old man with mild dementia presented with a 3-day history of anal pain. On digital rectal examination, we felt a hard and sharp object, which could not be manually removed due to its shape. Therefore, it was removed endoscopically. We inserted an endoscope with a large-caliber soft oblique cap and observed the PTP in the anal canal. It was successfully removed using grasping forceps. The patient was stable, with only mild anal fissures, and no serious complications such as perforation and bleeding were observed. It is generally recognized that a PTP that reaches the large intestine is naturally expelled. Even if a PTP could pass through the pylorus or the small intestine, it could still be difficult to discharge naturally from the anus without discomfort or pain, as in this case.

History Of

Under experimental conditions fully embryonated eggs of Trichocephalus vulpis hatch in the small intestine of dogs within 30 min. after the eggs are fed. The larvae penetrate the intestinal mucosa within 24 hr. after infection and at that time may be found deeply embedded. Between 48 and 96 hr. after infection the larvae become coiled and sluggish, and the majority are found lying at the base of the crypts of Lieberkühn in the upper levels of the small intestine. They do not work their way back to the lumen of the intestine for at least eight days, although there is some evidence that they may return to the lumen by the 10th day after infection and are then carried passively down to the large intestine. There is some minor tissue destruction by the larvae during their mucosal penetration.

Excessive hunting and poaching for commercial purpose of Varanus salvator in Indonesia can cause a decline in this animal population. However, the scientific information of this animal especially about the biologic of organ system is rarely reported. Therefore, this case opens up opportunities for researching, which aims to study the anatomy of digestive tract of water monitor macroscopically. This research has been conducted in Biology Laboratory, University of Muhammadiyah Kupang for 5 months from March to August 2016. The digestive organ of this animal that has been preserved in alcohol 70% was obtained before from two males of water monitors. Preservation process: the animal were anesthetized, exsanguinated, and fixated in 4 paraformaldehyde by tissue perfusion method. Observations were performed to the visceral site and morphometrical of digestive tract. The resulted data was analysed descriptively and presented in tables and figures. The digestive tract of water monitor consist of esophagus, stomach, small intestine, large intestine and cloaca. The dimension of each organ is different based on its structures and functions. The esophagus of water monitor connects the mouth cavity and the stomach and also as the entrance of food to the stomach. Water monitor stomach were found in cranial part of abdomen, in left side of liver. The small intestine was longer than stomach and it is a winding muscular tube in abdomen in posterior side of liver. The large intestine consist of colon and cloaca, while cecum was not found. This channel was extend lateromedially in abdomen to cloaca between left and right kidneys. The cloaca was the end of digestive tract which excreted feces and urine. From this research, we can conclude that the digestive tract of water monitor consists of esophagus, stomach, small intestine, and large intestine. It’s difficult to differentiate small intestine and large intestine because there are no cecum.

Differential diagnosis of globus sensation in an otherwise asymptomatic patient should include hypopharyngeal fibrovascular polyp to avoid potentially fatal complications like airway compromise following regurgitation. We present a case of a 74-year-old man with a 13-cm long hypopharyngeal fibrovascular polyp with 9 months history of globus sensation. A narrow stalk of the giant polyp allowed endoscopic removal and complete resection with the CO2 laser. Histopathological examination was conclusive for the fibrovascular polyp.

Lipophilic Phycotoxins

Okadaic acid (OA) and its main structural analogs dinophysistoxin-1 (DTX1) and dinophysistoxin-2 (DTX2) are marine lipophilic phycotoxins distributed worldwide that can be accumulated by edible shellfish and can cause diarrheic shellfish poisoning (DSP). In order to study their toxicokinetics, mice were treated with different doses of OA, DTX1, or DTX2 and signs of toxicity were recorded up to 24 h. Toxin distribution in the main organs from the gastrointestinal tract was assessed by liquid chromatography-mass spectrometry (LC/MS/MS) analysis. Our results indicate a dose-dependency in gastrointestinal absorption of these toxins. Twenty-four hours post-administration, the highest concentration of toxin was detected in the stomach and, in descending order, in the large intestine, small intestine, and liver. There was also a different toxicokinetic pathway between OA, DTX1, and DTX2. When the same toxin doses are compared, more OA than DTX1 is detected in the small intestine. OA and DTX1 showed similar concentrations in the stomach, liver, and large intestine tissues, but the amount of DTX2 is much lower in all these organs, providing information on DSP toxicokinetics for human safety assessment.

Eight pigs were given a semi-purified diet based on maize flour and casein containing 10 μg biotin/kg. The diet was given ad lib. with or without a supplement of 70 μg biotin/kg diet from 5 to 94 d of age. The flow of biotin in the stomach was similar to the biotin intake (13.5 and 112 μg/d) for the unsupplemented and biotin-supplemented pigs respectively. The flow of biotin through the small intestine decreased for the biotin-supplemented pigs from 39 μg/d in the first quarter of the small intestine to 7.9 μg/d in the last quarter. The flows of biotin in the caecum, large intestine and colon were similar for both the unsupplemented and biotin-supplemented pigs, with values of 17–54 μg/d, indicating the synthesis of biotin in the hind-gut.

Malignant melanoma of the gastrointestinal tract is an uncommon neoplasm that could be primary or metastatic. Small intestine represents the most common site for the metastatic melanoma; however, it could be found anywhere in the gastrointestinal tract. Intussusception is a rare cause of intestinal obstruction in adults compared to children. In 90% of the cases, the underlying cause can be found, and in 65% of the cases, intussusception is caused by the neoplastic process. The majority of the neoplasms are benign, and about 15% are malignant. Metastatic melanoma is one of the most common metastatic malignancies to the gastrointestinal tract; however, the premortem diagnosis is rarely made. Here, we report an uncommon clinical presentation of metastatic melanoma causing intussusception in an 80-year-old man. This diagnosis should be considered in a differential diagnosis in any patient who presents with gastrointestinal symptoms and a history of melanoma.

Human anatomy is the science where human body structures are designed to enable complete physiological action thus establishing homeostasis of the human body. Acharya Sushruta had a keen observation about the human body reflecting that without the absolute knowledge of Rachana Sharir. Chikitsak cannot be considered an expert. In Ayurveda, the part of G.I.T. is mentioned in Koshthanga by various Acharya. These Koshthanga are Aamashaya, Pakwashaya, Purishdhara, Uttarguda, Adharguda, Kshudrantra etc. which are situated within the koshtha. In modern anatomy, G.I.T. or Alimentary canal includes all the structures between the mouth and anus, forming a continuous passageway that includes the main organ of digestion, namely the stomach small intestine and large intestine, each part of the Gastric intestinal tract is adapted to its specific function. The 'oesophagus' function primarily to conduct food rapidly from the pharynx to the stomach mixing along with the digestive juic- es, carrying out partial digestion and then propelling the food into the duodenum is the function of the stomach small intestine is designed for complete digestion and absorption of nutrients. Absorption of water and electrolyte from the chyme to form solid faeces is the function of the large intestine. Pakwashaya is the main organ related to the site of Vata Dosha, Purishvaha srotas, Purishdhara kala, Koshthanga and Aashaya. Pakwashaya plays an important role in formation of urine and digestion of food. Keywords: Pakwashaya, Purish

Abstract. Substantial insight into earthquake source processes has resulted from considering frictional ruptures analogous to cohesive-zone shear cracks from fracture mechanics. This analogy holds for slip-weakening representations of fault friction that encapsulate the resistance to rupture propagation in the form of breakdown energy, analogous to fracture energy, prescribed in advance as if it were a material property of the fault interface. Here, we use numerical models of earthquake sequences with enhanced weakening due to thermal pressurization of pore fluids to show how accounting for thermo-hydro-mechanical processes during dynamic shear ruptures makes breakdown energy rupture-dependent. We find that local breakdown energy is neither a constant material property nor uniquely defined by the amount of slip attained during rupture, but depends on how that slip is achieved through the history of slip rate and dynamic stress changes during the rupture process. As a consequence, the frictional breakdown energy of the same location along the fault can vary significantly in different earthquake ruptures that pass through. These results suggest the need for re-examining the assumption of pre-determined frictional breakdown energy common in dynamic rupture modeling and for better understanding of the factors that control rupture dynamics in the presence of thermo-hydro-mechanical processes.
