A curious case of foreign body induced jejunal obstruction and perforation

INTRODUCTION

Accidental and unnoticed ingestion of foreign bodies are not very uncommon. Most of such foreign bodies pass through gastrointestinal tract uneventfully and only on rare instances cause obstruction and/or perforation.

PRESENTATION OF CASE

We are reporting a case in which a 45 yr old male presented to accident and emergency department of our institute with complaints of pain abdomen, greenish vomiting, abdominal distension, fever and non passage of flatus and stool following alcoholic binge 15 days back. On presentation tachycardia, hypotension, generalised abdominal tenderness and guarding were present. After initial resuscitation and investigation diagnosis of perforation peritonitis was made and emergency exploratory lapratomy was done and a single perforation with plastic foreign body protruding through it was found in jejunum 5 cm distal to duodeno-jejunal junction.

DISCUSSION

The majority of ingested FBs that reach the stomach pass uneventfully through the gastrointestinal tract. The majority of cases occur in children. Only 1% of patient of patients requires surgical intervention depending upon nature, size and shape of the foreign body.

CONCLUSION

Present case report intends to draw the attention towards possibility of intestinal obstruction and perforation by a single plastic foreign body. High index of suspicion is needed as this foreign body is not even radio-opaque and cannot be picked up in X-ray investigations. Also with increasing use of such plastic materials there are increased chances of such incidents.     

Simple hepatic cyst causing inferior vena cava thrombus

INTRODUCTION

Thrombosis of the inferior vena cava (IVC) is governed by Virchow''s triad of stasis of blood flow, endothelial damage and hypercoagulability. Causes may be secondary to malignancy, congenital anomalies or other infrequent events such as external compression. We present a case of external compression of the IVC leading to extensive thrombus burden secondary to a benign hepatic cyst.

PRESENTATION OF CASE

A 72 year old African American female presented to the emergency department with new onset shortness of breath, right lower extremity weakness and swelling. CT imaging demonstrated multiple hepatic cysts compressing the IVC, leading to extensive clot burden. Treatment with heparin drip was initiated without resolution of her symptoms. Transcatheter mechanical thrombectomy and tPA infusion was performed. After 24 h, swelling and weakness were nearly resolved. The patient was bridged to therapeutic low molecular weight heparin in preparation for surgery.

DISCUSSION

Management of IVC thrombosis has typically been with a heparin drip and transition to oral anticoagulants. Thrombolysis has been shown to promote complete clot lysis more often than compared to standard anticoagulant therapy. In addition, venous patency was better maintained.

CONCLUSION

We feel that the added benefit of short term effects of improved venous patency and long term benefits of less post thrombotic syndrome, catheter based tPA administration and mechanical thrombectomy for thrombus offers an adjuvant treatment in the setting of large clot burden refractory to standard treatment.     

A rapid tube ELISA for human IgG in body fluids using Staphylococcus aureus

An ELISA was designed for measurement of human IgG in urine and CSF using protein A containing Staphylococcus aureus as sorbent. This assay was performed in test tubes. An OD difference of approximately 1.0 was developed between non-specific binding and 10 μg/ml IgG solution. The method has a sensitivity of 70 ng IgG/ml. The test is simple and rapid and does not require concentration of samples. Once prepared S. aureus reagent is stable for at least one year. The merits of this method in comparison to radial immunodiffusion (RID) are discussed.     

Autoimmunity against the β2 adrenergic receptor and muscarinic-2 receptor in complex regional pain syndrome

Complex regional pain syndrome (CRPS) is a painful condition affecting one or more extremities of the body, marked by a wide variety of symptoms and signs that are often difficult to manage because the pathophysiology is incompletely understood. Thus, diverse treatments might be ineffective. A recent report revealed the presence of autoantibodies against differentiated autonomic neurons in CRPS patients. However, it remained unclear how the antibodies act in the development of CRPS. We therefore aimed to characterize these antibodies and identify target antigens. Functional properties of affinity-purified immunoglobulin G of control subjects or CRPS patients were assessed using a cardiomyocyte bioassay. Putative corresponding receptors were identified using antagonistic drugs, and synthesized peptide sequences corresponding to segments of these receptors were used to identify the target epitopes. Chinese hamster ovary cells were transfected with putative receptors to ensure observed binding. Further, changes in the intracellular Ca²⁺ concentration induced by agonistic immunoglobulin G were measured using the Ca²⁺-sensitive fluorescent dye fura-2 assay. Herein, we demonstrate the presence of autoantibodies in a subset of CRPS patients with agonistic-like properties on the β₂ adrenergic receptor and/or the muscarinic-2 receptor. We identified these autoantibodies as immunoglobulin G directed against peptide sequences from the second extracellular loop of these receptors. The identification of functionally active autoantibodies in serum samples from CRPS patients supports an autoimmune pathogenesis of CRPS. Thus, our findings contribute to the further understanding of this disease, could help in the diagnosis in future, and encourage new treatment strategies focusing on the immune system.     

The effects of aerobic exercise on glucose and counterregulatory hormone concentrations in children with type 1 diabetes

OBJECTIVE: To examine the acute glucose-lowering effects of aerobic exercise in children and adolescents with type 1 diabetes. RESEARCH DESIGN AND METHODS: Fifty children and adolescents with type 1 diabetes (ages 10 to <18 years) were studied during exercise. The 75-min exercise session consisted of four 15-min periods of walking on a treadmill to a target heart rate of 140 bpm and three 5-min rest periods. Blood glucose and plasma glucagon, cortisol, growth hormone, and norepinephrine concentrations were measured before, during, and after exercise. RESULTS: In most subjects (83%), plasma glucose concentration dropped at least 25% from baseline, and 15 (30%) subjects became hypoglycemic (< or = 60 mg/dl) or were treated for low glucose either during or immediately following the exercise session. The incidence of hypoglycemia and/or treatment for low glucose varied significantly by baseline glucose, occurring in 86 vs. 13 vs. 6% of subjects with baseline values <120, 120-180, and >180 mg/dl, respectively (P < 0.001). Exercise-induced increases in growth hormone and norepinephrine concentrations were marginally higher in subjects whose glucose dropped < or = 70 mg/dl. Treatment of hypoglycemia with 15 g of oral glucose resulted in only about a 20-mg/dl rise in glucose concentrations. CONCLUSIONS: In youth with type 1 diabetes, prolonged moderate aerobic exercise results in a consistent reduction in plasma glucose and the frequent occurrence of hypoglycemia when preexercise glucose concentrations are <120 mg/dl. Moreover, treatment with 15 g of oral glucose is often insufficient to reliably treat hypoglycemia during exercise in these youngsters.     

Anestesia em criança operada para lábio leporino associado à síndrome de Patau

Patients with Patau's syndrome (Trisomy 13) have multiple craniofacial, cardiac, neurological and renal anomalies with very less life expectancy. Among craniofacial anomalies cleft lip and palate are common. These craniofacial and cardiac anomalies present difficulties with anesthesia. We therefore describe the anesthetic management in the case of a Trisomy 13 child for operated for cleft lip at 10 months of age.     

Analgesic efficacy of laparoscopic-guided transverse abdominis plane block using liposomal bupivacaine in bariatric surgery

Background

Postoperative pain management is a major contributor to recovery and discharge in bariatric surgery. Local anesthetic agents are of particular interest: they're non-sedating and may reduce postoperative pain and hospital length of stay (LOS).
