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 multi-stage malaria vaccine candidate targeting both transmission and asexual parasite life-cycle stages

Effective control and eventual eradication of malaria drives the imperative need for clinical development of a malaria vaccine. Asexual parasite forms are responsible for clinical disease and death while apathogenic gametocytes are responsible for transmission from man to mosquito. Vaccines that combine antigens from both stages may provide direct protection and indirect benefit by reducing the force of infection. We constructed a chimeric antigen composed of a fragment of the Plasmodium falciparum (Pf) glutamate-rich protein fused in frame to a correctly folded fragment of Pfs48/45. The chimera was produced in Lactococcus lactis and induced robust antibody responses in rodents to the individual components. Specific antibodies showed strong transmission blocking activity against multiple Pf-strains in the standard membrane feeding assay and functional activity against asexual stages in the antibody dependent cellular inhibition assay. The combined data provide a strong rationale for entering the next phase of clinical grade production and testing.
