Intussusception in a premature neonate: A rare and often misdiagnosed clinical entity

Intussusception is a very rare cause of intestinal obstruction in neonates. It is of extremely rare occurrence among premature neonates. We present a case of 11-day-old premature neonate who presented with abdominal distension, intolerance to feeds, vomiting, significant bilious aspirate and bleeding per rectum. The initial diagnosis of necrotizing enterocolitis (NEC) led to a delay in the diagnosis. On exploratory laparotomy, it turned out to be a case of ileo-colic intussusception with Meckel''s diverticulum as a lead point. This site of intussusception (ileo-colic) and presence of a lead point among premature neonate is of exceedingly rare occurrence and very few such cases have been reported.In this article, the published work about clinical features and management on intussusceptions in premature neonates has been reviewed. The authors intend to highlight the difficulty in distinguishing the NEC and intussusception. Subtle clinical and radiological features which can help in differentiating the two conditions have been emphasized. This can avoid the delay in diagnosis and management which can prove critical. High index of suspicion with timely intervention is the key for optimizing outcome. A diagnosis of intussusception should always be considered in any preterm infant with suspected NEC.

Gun shot wound neck

All penetrating neck wounds are potentially very dangerous and require emergency treatment. The choice of treatment for the stable patient remains controversial, a number of studies encouraging mandatory surgical exploration and a similar number encourage selective surgical exploration. Knowledge of the physical properties of the penetrating object or weapon can help to determine a treatment plan and predict the risk of injury- All tracheal and esophageal injuries with structural damage should be repaired primarily. A case of Gun Shot Wound Neck was air evacuated to Army Hospital R & R Delhi Cantt in a tracheostomised state. Patient was evaluated in detail, he had trachea esophageal fistula. The management of this case is discussed along with principles of management of war injuries.     

Laparoscopic treatment of Meckel's diverticulum

We present two cases in which complication of a Meckel's diverticulum were dealt with, and in one case diagnosed using the laparoscope. One was a large bleeding diverticulum containing ectopic gastric mucosa, with the diagnosis suggested preoperatively, confirmed laparoscopically, and the pathology resected extracorporeally. The second was a partial intermittent small-bowel obstruction due to torsion around the mesodiverticular band, diagnosed and resected via the laparoscope. The literature of Meckel's diverticula and complications is reviewed, with open and laparoscopic treatment options. Although uncommon, many cases of Meckel's diverticulum may be quite suitable for laparoscopic diagnosis and treatment.     

大鼠气管上皮细胞体内—体外转化模型的研究

本研究建立了大鼠气管上皮细胞体内－体外转化模型，大鼠气管内滴注苯并芘，三天后处死大鼠，消化气管上皮细胞，接种于无血清完全培养基。细胞形成集落后，换为选择培养基继续培养五周，统计转化率。结果显示，２５ｍｇ／ｋｇ和５０ｍｇ／ｋｇ的苯并芘可诱导大鼠气管上皮细胞转化及微核增加，用同样方法研究了煤焦沥青提取物，结果表明，剂量为８ｍｇ／ｋｇ和２５ｍｇ／ｋｇ的煤焦沥青提取物能明显诱导大鼠气管上皮细胞转化。     

气管与主支气管肿瘤的影像诊断（附32例报告）

作者对３２例经病理证实的气管与主支气管良、恶性肿瘤的影像学表现进行分析，归纳为３型：腔内型、壁增厚型和腔内外型。后２种类型提示恶性，而无蒂的腔内型表现者不能鉴别良，恶性。作者还评价了常规体层、ＣＴ及ＭＲＩ诊断气管与主支气管肿瘤的优、缺点，讨论了影像诊断的作用。     

ENDOSCOPIC MANAGEMENT OF A DIEULAFOY‐LIKE LESION IN A DUODENAL DIVERTICULUM

We present a 70‐year‐old man who had two episodes of melena during the preceding 8‐year period. He had a Dieulafoy‐like lesion in a diverticulum in the third portion of the duodenum. While emergency endoscopy revealed neither apparent blood nor clots around the diverticular orifice, there was a non‐bleeding vessel in the fundus of the diverticulum. The vessel ceased bleeding after argon plasma coagulation and, since then, the patient has not experienced bleeding. In cases of gastrointestinal bleeding of obscure origin, duodenal diverticulum should be considered as a possible source of bleeding, even when endoscopy discloses no apparent bleeding.
