Progressive atypical peripheral neuropathy following nephrectomy in a patient with renal cell carcinoma

Guillain-Barre syndrome: a typical paraneoplastic syndrome in a kidney transplant recipient with allograft renal cell carcinoma: a case report and review of the literature

BACKGROUND

Guillain-Barré syndrome (GBS) is an autoimmune polyneuropathy affecting the peripheral nervous system. This neurological disorder has been previously reported in bone marrow transplant recipients but is uncommon after kidney transplantation. Viral infections and calcineurin inhibitors are the main triggers of GBS in renal transplant recipients.

CASE PRESENTATION

In this report, we present a case of a 47-year-old male patient 12 years after his second kidney transplantation who developed GBS due to papillary renal cell carcinoma. Infectious and drug-related origins of GBS were excluded. Despite intensive treatment, graftectomy was performed, after which neurological symptoms resolved.

CONCLUSIONS

In kidney transplant recipients, paraneoplastic aetiology should be considered in the differential diagnosis of GBS.

Chronic inflammatory demyelinating polyneuropathy and malignancy: A systematic review

A systematic review of the literature was performed on the association of chronic inflammatory demyelinating polyneuropathy (CIDP) with malignancy. Hematological disorders are the most common association, particulalry non-Hodgkin lymphoma. CIDP frequently precedes the malignancy diagnosis, and there is a favorable CIDP response to treatment more than 70% of the time. Melanoma is the second most common association and may be accompanied by antiganglioside antibodies; CIDP shows a good response to immunotherapy. Other cancers are rare, with variable timings and presentations but good responses to immunomodulation and/or cancer therapy. Unusual neurological features such as ataxia, distal/upper limb predominance, or cranial/respiratory/autonomic involvement may suggest associated malignancy as may abdominal pain, diarrhea/constipation, poor appetite/weight loss, dermatological lesions, and lymphadenopathy. In the appropriate clinical and electrophysiological setting, CIDP associated with cancer should be considered. Immunomodulatory therapy, cancer treatment alone, or a combination may be effective.

Demyelinating Peripheral Neuropathy Due to Renal Cell Carcinoma

Renal cell carcinoma (RCC) patients who develop a paraneoplastic syndrome may present with neuromuscular disorders. We herein report the case of a 50-year-old man who suffered from progressive gait disturbance and muscle weakness. The results of a nerve conduction study fulfilled the criteria of chronic inflammatory demyelinating polyneuropathy. An abdominal CT scan detected RCC, the pathological diagnosis of which was clear cell type. After tumor resection and a single course of intravenous immunoglobulin therapy, the patient's symptoms drastically improved over the course of one year. The patient's neurological symptoms preceded the detection of cancer. A proper diagnosis and the initiation of suitable therapies resulted in a favorable outcome.

Efficacy of probiotics from anaerobic microflora with prebiotics on growth performance and noxious gas emission in growing pigs

We investigated the effect of probiotics from anaerobic microflora with prebiotics (synbiotics) on growth performance, noxious gas emission and fecal pathogenic bacteria populations in growing pigs. The basal diet, which contained approximately 25% corn, 24% whey, 12% wheat and 12% soybean meal, was supplemented alternatively with 0.15% antibiotics (US diet), prebiotics and 0.2% probiotics from anaerobic bacteria (BS diet), yeast (YS diet), mold (MS diet) or compounds (CS diet). One hundred and fifty pigs were fed an experimental diet for 15 days. Although the growth performance was not affected by supplemental synbiotics, the BS group showed higher dry matter and crude protein digestibility. The BS group decreased fecal ammonia and amine gas emissions, and increased fecal acetate gas emission compared with the US group. All synbiotics groups decreased in fecal propionate gas emission. Fecal Escherichia coli population was lower in the synbiotics groups than in the US group. Therefore, the results of the present study suggest that synbiotics exert similar effects with antibiotics on the nutrient digestibility and fecal microflora composition in growing pigs. Moreover, synbiotics can also decrease the fecal noxious gas emission in growing pigs.

Carcass weight, growth performance and internal organs size of broilers fed graded levels of Saccharomycese cervicia supplemented diets

The effects of graded levels of Saccharomyces cerviciae (SC) on performance, carcass characteristic and internal organs size of broilers were investigated in a seven weeks trial using 160 days old Cab 500 mal broiler chicks fed corn-soybean meal based diet. In a completely randomized design 160 chicks distributed to four dietary treatments. Thus each dietary treatment had 4 replication with 10 birds each. Four dietary treatment according to the Saccharomyces cervicia (SC) levels were S (0), S1 (100), S2 (300) and S3 (500 g kg(-1) diet). Each three levels of SC significantly (p < 0.05) affected the Feed Conversion Rate (FCR), during 7-21 days and S3 showed the best FCR but during 21-42 days the S1 was the best (p < 0.05). There was no significance differences in body weight gain (BW) and Feed Intake (FI) between the treatments. SC supplementation did not significantly (p > 0.05) affect Dressing Yield (DY) but dressing yield in SC containing treatments numerically were higher than control. Inclusion and levels of SC significantly (p < 0.05) affected, liver, spleen and Abdominal Fat (AF) weight. As the level of SC in diets increased the liver and spleen weight increased too. But abdominal fat decreased. Supplementation of SC significantly (p < 0.05) affected the intestinal (Large and Small) length (LI, SI), the shortest intestine measured on S3 receiving diet, while the highest intestine measured on bird receiving the control diet. The results demonstrated that compared to control diet supplemental SC significantly (p < 0.05) improve FCR, decrease abdominal fat, intestine length and apparently increase body weight gain, dressing yield, liver and spleen weights and 100 g kg(-1) SC diet give the best.
