Pneumoscrotum after tracheal intubation.

Air in the scrotum is an unusual clinical finding and a thorough search should be done in order to locate the air leak or source of gas production. We report an 81-year-old patient who developed severe acute respiratory failure after fiberoptic bronchoscopy and was intubated immediately. After tracheal intubation, excessive subcutaneous emphysema from the head to the scrotum was obvious. Chest tube thoracostomies were placed to treat pneumothorax. The emphysema was absorbed after 13 days without any sequela. Air or gas inside the scrotum may originate from intraperitoneal, extraperitoneal, or local sources. The majority of the cases can be managed conservatively, but emergent intervention is needed in life-threatening situations.

Pneumoscrotum as complication of blunt thoracic trauma: a case report.

Introduction. Pneumoscrotum is a rare clinical entity. It presents with swollen scrotal sac and sometimes with palpable crepitus. It has many etiologies. One of them is due to blunt trauma of the thoracic cage, causing pneumothorax and/or pneumomediastinum. Case Presentation. We report the case of an 82-year-old male who was transferred to the Emergency Department with signs of respiratory distress after a blunt chest trauma. A CT scan was obtained, and bilateral pneumothoraces with four broken ribs were disclosed. Subcutaneous emphysema expanding from the eyelids to the scrotum was observed, and a chest tube was inserted on the right side with immediate improvement of the vital signs of the patient. Discussion. Pneumoscrotum has three major etiologies: (a) local introduction of air or infection from gas-producing bacteria, (b) pneumoperitoneum, and (c) air accumulation from lungs, mediastinum, or retroperitoneum. These sources account for most of the cases described in the literature. Treatment should be individualized, and surgical consultation should be obtained in all cases. Conclusion. Although pneumoscrotum itself is a benign entity, the process by which air accumulates in the scrotum must be clarified, and treatment must target the primary cause.

Neuromesenchymal hamartoma of small bowel--an extremely rare entity: a case report.

Neuromuscular and vascular hamartoma (NMVH) is a very rare stricturing condition of the small intestine, occurring focally and causing recurrent obstructive symptoms or occult chronic gastrointestinal bleeding. Salas et al. (Neuromesenchymal hamartoma of the small bowel. J Clin Gastroenterol. 1990, 12 (6): 705-9) proposed the term of "Neuromesenchymal hamartoma" for the cases of NMVH with participation of mesenchymal tissues.We present the case of a 60-year-old male patient admitted twice in a month with abdominal pain. On the third admission with clinical signs of acute abdomen, an exploratory laparotomy was performed. The clinical and laboratory findings that occurred after the patient's evaluation, the intraoperative findings and the pathological features of this lesion are reported.

Comparison of nutritional deficiencies after Roux-en-Y gastric bypass and after biliopancreatic diversion with Roux-en-Y gastric bypass.

BACKGROUND: Patients undergoing either Roux-en-Y gastric bypass (RYGBP) or biliopancreatic diversion (BPD) with RYGBP are at risk of developing metabolic sequelae secondary to malabsorption. We compared the differences in nutritional complications between these two bariatric operations. METHODS: A retrospective analysis of a prospective database was done. From June 1994 to December 2001, 243 morbidly obese patients underwent various bariatric procedures at our institution. Of these patients, 79 (BMI 45.6 +/- SD = 4.9) who underwent RYGBP (gastric pouch 15 +/- 5 ml, biliopancreatic limb 60-80 cm, alimentary limb 80-100 cm and common limb the remainder of the small intestine), and 95 super obese (BMI 57.2 +/- 6.1) who underwent a BPD (gastric pouch 15 +/- 5 ml, biliopancreatic limb 150-200 cm, common limb 100 cm and alimentary limb the remainder of the small intestine), were selected and studied for the incidence of micronutrient deficiencies and level of serum albumin at yearly intervals postoperatively. A variety of nutritional parameters including Hb, Fe, ferritin, folic acid, vitamin B12 and serum albumin were measured preoperatively and compared postoperatively at 1, 3, 6, 12, 18 and 24 months, and yearly thereafter. RESULTS: Nutritional parameters were compared preoperatively and at similar periods postoperatively. No statistically significant (P < 0.05) difference in the occurrence of deficiency was observed between the groups for any of the nutritional parameters studied, except for ferritin, which showed a significant difference at the 2-year follow-up (37.7% low ferritin levels after RYGBP vs. 15.2% after BPD, P = 0.0294). All of these deficiencies were mild, without clinical symptomatology and were easily corrected with additional supplementation of the deficient micronutrient, with no need for hospitalization. Regarding serum albumin, there was only one patient with a level below 3 g/dl in the RYGBP group and two in the BPD group. These three patients were hospitalized and received total parenteral nutrition for 3 weeks, without further complications. CONCLUSION: There was no significant difference in the incidence of deficiency of the nutritional parameters studied, except for ferritin, following RYGBP vs. BPD with RYGBP. The most common deficiencies encountered were of iron and vitamin B12. The incidence of hypoalbuminemia was negligible in both groups, with mean values above 4 g/dl.
