Pentadecapeptide BPC 157 as Therapy for Inferior Caval Vein Embolization: Recovery of Sodium Laurate-Post-Embolization Syndrome in Rats.

After inferior caval vein embolization therapy, post-embolization syndrome (sodium laurate 10 mg/kg, 0.1 mL into rat inferior caval vein, assessment at 15, 30, 60 min, prime lung lesions, thromboemboli occluding lung vessels), as a severe occlusion/occlusion-like syndrome, might be resolved as a whole by stable gastric pentadecapeptide BPC 157 therapy. At 5 min after laurate injection, stable gastric pentadecapeptide BPC 157 was implemented as therapy (10 µg/kg, 10 ng/kg intraperitoneally or intragastrically). As before, confronted with the occlusion of major vessel(s) or similar noxious procedures, such as rapidly acting Virchow triad circumstances, the particular effect of the therapy (i.e., collateral pathways activation, "bypassing vascular key", i.e., direct blood flow delivery via activation of azygos vein) assisted in the recovery of the vessel/s and counteracted multiorgan failure due to occlusion/occlusion-like syndrome as a whole in the laurate-injected rats. Along with prime lung lesions and thromboemboli occluding lung vessels, post-embolization syndrome rapidly occurred peripherally and centrally as a shared multiorgan and vessel failure, brain, heart, lung, liver, kidney, and gastrointestinal tract lesions, venous hypertension (intracranial (superior sagittal sinus), portal, and caval), aortal hypotension, progressing thrombosis in veins and arteries and stasis, congested and/or failed major veins, and severe ECG disturbances. Whatever the cause, these were all counteracted, eliminated, or attenuated by the application of BPC 157 therapy. As recovery with BPC 157 therapy commonly and rapidly occurred, reversing the collapsed azygos vein to the rescuing collateral pathway might initiate rapid direct blood delivery and start blood flow reorganization. In conclusion, we suggest BPC 157 therapy to resolve further vascular and embolization injuries.

Fine-needle aspiration cytology of apocrine hidradenoma.

An apocrine hidradenoma is a benign adnexal neoplasm, usually covered by intact skin, but may show superficial ulceration and serous discharge. This feature is raising the possibility of malignancy as it was in our case of macroscopically suspicious tumour. We described cytomorphologic features of cutaneous nodule that might be a lead to the cytologic diagnosis of hidradenoma, but primary or secondary malignant tumour has been ruled out first.

Fine needle aspiration cytology of chondroid syringoma.

Chondroid syringoma (CS) is a rare, benign, appendageal tumor with diagnostic feature of myxochondroid stroma supporting eccrine and apocrine epithelial structures. The usual presentation is a painless, slowly growing mass, typically located in the head and neck region. It usually affects middle-aged and older male patients. Because of its unremarkable clinical presentation it is often overlooked. It should be included in the differential diagnosis of cutaneous head and neck tumors, especially in middle-aged men. Optimal treatment of CS is total surgical excision. We present a 63 year-old man with a small nodule on the neck with 5 years of duration. The diagnosis was made initially on fine needle aspiration cytology that was performed by ultrasound guidance and confirmed subsequently by histology. FNA cytology may be very useful to determine diagnosis before excision.

The importance of urgent cytological examination of synovial fluids in differentiation inflammatory and non-inflammatory joint diseases.

The aim of this study was to imply the possibilities of the urgent cytological examination of synovial fluids in differential diagnosis of arthropathies and to motivate the clinicians to use this method. It gave valuable information particularly with respect to differentiate the inflammatory and non-inflammatory joint diseases. This study included 115 synovial fluids obtained by fine needle aspiration (FNA) of the swollen knee from the patients in the period between 2003 and 2008. At our department the urgent cytological examination of the synovial fluids consisted of macroscopic analysis that includes volume, colour, clarity, viscosity and mucin clot test, native microscopic analysis for crystals and tissue fragments, counting the total nucleated cell count and semiquantitative microscopic analysis for neutrophil granulocyte percentage on the slides stained with Hemacolor rapid staining. All cytological analyses were done within one hour since FNA. According to our results the clarity, viscosity, mucin clot test, the total nucleated cell count and the neutrophil granulocyte percentage enabled distinction between inflammatory and non-inflammatory diseases with statistically significant difference at the 0.01 level but we could not differentiate these two groups of illnesses according to volume and colour. In inflammation the total nucleated cell count and the neutrophil granulocyte percentage was greater than in non-inflammation, the clarity was only translucent and opaque, the viscosity was low and the mucin clot test was negative. In non-inflammatory diseases the clarity varied from transparent to opaque, the total nucleated cell count and the neutrophil granulocyte percentage was smaller than in inflammatory diseases, the viscosity was high and consequently the mucin test was highly positive in all samples. Crystals were detected in only 12 samples of synovial fluids, mostly in inflammation and they were all monosodium urate (MUS) so we could diagnose gout. We could conclude that the urgent cytological analysis of the synovial fluid is a very useful, simple and reliable basic diagnostic screening test in differentiation inflammatory and non-inflammatory joint diseases and we recommended using it as the initial test in the diagnostic procedure of these illnesses using our protocol.
