Levofloxacin is a fluoroquinolone antibacterial drug effective in the treatment of bacterial conjunctivitis. The objective of the present work was to develop ocular inserts of levofloxacin and evaluate their potential for sustained ocular delivery. Conventional ophthalmic solution shows the poor bioavailability and therapeutic response due t many pre-corneal constraints. These constrains necessitates the controlled and sustained drug delivery to become standard one in modern pharmaceutical era Matrix type ocular inserts were prepared by the film casting technique in Teflon coated Petri dishes and characterized in vitro by drug release studies using a flow through apparatus that simulated the eye conditions. Nine formulations were developed, which differed in the ratio of polymers - chitoson, polyvinyl alcohol (PVA). All the formulations were subjected to evaluation of thickness, weight variation, folding endurance, drug content uniformity, in vitro release study, Surface pH, Swelling Studies (Swelling Index), % Moisture absorption, Release Kinetics, and Ocular Irritation Studies. On the basis of in vitro drug release studies, the formulation L9 was found to be better than the other formulations and it was selected as an optimized formulation.

Percutaneous nephrolithotomy (PCNL) has been an excellent option for the management of kidney stones. There have been many complications in regards to solid organ injury during PCNL. Here we discuss an interesting case of 45-year-old woman, who underwent PCNL for right renal staghorn calculus, and had an accidental puncture of the gall bladder. Post operatively, the patient was conservatively managed and recovered well. A small number of cases has been reported until now in literature.

Adenomas of the extrahepatic biliary tuce are rare and common bile duct adenomas are rare too. They may be pessile or pedunculated our patient was a 60 years old lady who presented with RUQ pain and jaundice so with impression of cholangitic under weat laparotomy, cholecystectomy, CBD explouation and choledochoduodestomy. During CBD exploration a 0.5×0.5 cm of CBD identified that excised. Histopathology confirmed the diagnosis of CBD adenoma and the patient discharged 6 days later with no complication.

Management delle colecistopatie in età pediatrica. Aspetti medici e chirurgici. Introduzione/Scopi: Sebbene la patologia colecistica sia poco comune in età pediatrica, la sua incidenza è aumentata negli ultimi anni.Lo scopo è stato quello di valutare il management del bambino con patologia colecistica presso il Dipartimento di Pediatria e Chirurgia Pediatrica della Seconda Università di Napoli. Metodi: Abbiamo effettuato una analisi retrospettiva sugli ultimi 9 anni di management della patologia colecistica in età pediatrica da Aprile 2000 a Febbraio 2009. Per ciascun paziente è stata compilata una scheda comprendente i dati demografici, la storia clinica, etiologia, sintomatologia, aspetti e numero dei calcoli, indagini di laboratorio e studio per immagini, reperto istologico, terapia e follow-up. Risultati:L’età media è stata di 6,6 anni. Quindici pazienti sono stati sottoposti a colecistectomia e in nessun caso sono state riportate complicanze postoperatorie. Nove pazienti con colelitiasi asintomatica non hanno ricevuto alcun trattamento e sono stati seguiti con controlli clinici ed ecografici; in nessun caso si è avuta evoluzione verso una complicanza. Conclusioni: Nei pazienti con colelitiasi asintomatica è indicato l’approccio conservativo con controlli clinici ed ecografici. La colecistectomia laparoscopica è stata confermata efficace ed utile nel trattamento della colelitiasi in età pediatrica. Management of gallbladder disease in pediatric population. Medical and surgical aspects. BACKGROUND/PURPOSE: Although gallbladder disease is relatively uncommon in the pediatric population, its incidence has been rising in recent years. The Aim was to evaluate the management of children with gallbladder diseas at Pediatric and Surgical Department of Second University of Naples. Methods: We performed a retrospective analysis of our most recent 9-years experience with management of gallbladder disease in pediatric population between April, 2000 and February, 2009. Data were collected by an tab included patient demographics, clinical history, etiology, presentation,gallstones number and aspects, laboratory and imaging studies, histologic findings, therapy and follow-up. Results: The mean age was 6,6 years. Fifthy patients were treated with cholecystectomy and in no case a postoperative complication was reported. Nine patients with asymptomatic gallstones received no treatment and were followed with clinical and echographic controls; in no case the development of complications was reported. Conclusion: In patients with asymptomatic gallstones is useful a conservative therapy with clinical and echographic controls. Laparoscopic cholecystectomy was confirmed to be an efficacy and safe tretment for pediatric gallstones.

A ultra-sonografia (US) é uma das técnicas de exame complementar eletivas para o diagnóstico de enfermidades hepáticas de diversas espécies domésticas. Em ovinos, no entanto, existem poucos relatos sobre o aspecto ultra-sonográfico de enfermidades hepáticas e não há definição precisa dos padrões anatômicos da US normal do fígado. Neste estudo foram utilizados 58 ovinos da raça Santa Inês: n1=8 machos, n2=10 fêmeas não gestantes e n3=40 fêmeas gestantes. Os animais foram escaneados do 12º ao 8º espaços intercostais (EI) para se observar a localização da veia cava caudal (VC), veia porta (VP) e vesícula biliar (VB) e para se aferir a espessura do fígado sobre a VC e VP no 11º e 10º EI. O fígado foi examinado de forma satisfatória do 12º até o 8º EI. Nesta área, tanto a VC como a VP, foram observadas do 12º ao 9º EI, porém a VC não foi examinada de forma adequada em 11 animais, 10 com peso acima de 50kg. Entre os dois grupos de fêmeas, a VC e a VP foram observadas com maior freqüência no 11º e 10º EI e em todos os machos examinados do 12º ao 10º EI. A localização da vesícula biliar oscilou entre o 10º e o 8º EI, com maior incidência a nível do 9º e 8º EI nas fêmeas gestantes e não gestantes, e sobre o 9º EI nos machos. Comparativamente, a ecogenicidade do parênquima hepático foi mais intensa do que a do córtex renal. Houve correlação significativa entre o peso do fígado e a espessura hepática sobre a veia porta no 11º e o 10º EI no grupo de fêmeas gestantes. A US forneceu informações importantes quanto a topografia e ecogenicidade do fígado e mostrou ser uma ferramenta útil para estimar o peso do órgão. The ultrasonography (US) is a complementary technique of choice for the diagnostic of hepatic diseases in many domestics' species. In sheep however there are few reports about ultrasonography in hepatic diseases and there is not precise definition about the anatomic standards of normal liver limits in ultrasonographic examination. In this study 58 Santa Inês sheep breed were used and divided in 3 groups: n1=8 males, n2=10 not pregnant females and n3=40 pregnant females. The animals were scanned from the 12º to 8º intercostal spaces (EI) to observe the localization of the vena cava caudal (VC), gallbladder (VB) and to measure the liver thickness above the VC and vena portae VP under the 11º and 10º EI. The liver was examined on satisfactory way from the 12º till the 8º EI. Both the VC and the VP where observed from the 12º to 9º EI, however the VC could not be observed in 11 animals, 10 of them were over 50 kg. Between the two female groups the VC and VP where observed most frequently from the 11º to 10º EI and in all males examined from the 12º to 10º EI. The location of the gallbladder varies between the 10º to the 8º EI, with bigger incidence between the 9º and the 8º EI in pregnant and no pregnant females groups and underneath the 9º EI on the male group. Comparatively, the ecogenicity of the liver parenchyma was more intense than kidney cortex. There was a significant correlation between liver's weight and hepatic thikness above the vena portae on the 11º and 10º EI on the pregnant females group. The US supplied to important information about the topography and echogenicity of the liver and showed to be a useful tool to esteem the liver's weight.

The ultrastructure of the developmental stages of the myxozoan Enteromyxum leei parasitizing gilthead seabream (Sparus aurata) intestine and sharpsnout sea bream (Diplodus puntazzo) intestine and gallbladder are described. The earliest stage observed was a small dense trophozoite located among enterocytes. Proliferative stages, observed intercellularly in the epithelium of the intestine and gallbladder as well as in the lumen, possessed the typical cell-in-cell configuration throughout their development. Secondary cells were seen undergoing division within a common vacuolar membrane that also encompassed pairs of tertiary cells. Cytochemical studies showed that primary cells stored mainly lipids whereas secondary cells stored abundant β-glycogen granules. Sporogonic development resembled that described for other disporous myxozoans. Within sporogonic stages, nonsporogonic secondary cells were observed accompanying two developing spores. Mature spores had a binucleated sporoplasm in which glycogen stores were abundant and no sporoplasmosomes were found. Our observations are discussed in relation to our knowledge on other myxozoans of the genus Enteromyxum., This study was funded by the European Union through a re-search project QLRT-2001-00722 (MyxFishControl).

10 pages, 8 figures, 2 tables., Ellagitannin-containing foods (strawberries, walnuts, pomegranate, raspberries, oak-aged wine, etc.) have attracted attention due to their cancer chemopreventive, cardioprotective, and antioxidant effects. Ellagitannins (ETs) are not absorbed as such but are metabolized by the intestinal flora to yield urolithins (hydroxydibenzopyran-6-one derivatives). In this study, Iberian pig is used as a model to clarify human ET metabolism. Pigs were fed either cereal fodder or acorns, a rich source of ETs. Plasma, urine, bile, lumen and intestinal tissues (jejunum and colon), feces, liver, kidney, heart, brain, lung, muscle, and subcutaneous fat tissue were analyzed. The results demonstrate that acorn ETs release ellagic acid (EA) in the jejunum, then the intestinal flora metabolizes EA sequentially to yield tetrahydroxy- (urolithin D), trihydroxy- (urolithin C), dihydroxy- (urolithin A), and monohydroxy- (urolithin B) dibenzopyran-6-one metabolites, which were absorbed preferentially when their lipophilicity increased. Thirty-one ET-derived metabolites were detected, including 25 urolithin and 6 EA derivatives. Twenty-six extensively conjugated metabolites were detected in bile, glucuronides and methyl glucuronides of EA and particularly urolithin A, C, and D derivatives, confirming a very active enterohepatic circulation. Urolithins A and B as well as dimethyl-EA-glucuronide were detected in peripheral plasma. The presence of EA metabolites in bile and in urine and its absence in intestinal tissues suggested its absorption in the stomach. Urolithin A was the only metabolite detected in feces and together with its glucuronide was the most abundant metabolite in urine. No metabolites accumulated in any organ analyzed. The whole metabolism of ETs is shown for the first time, confirming previous studies in humans and explaining the long persistency of urolithin metabolites in the body mediated by an active enterohepatic circulation., This work has been funded by Spanish MEC and FEDER funds (AGL2004-03989) and the EU Commission (FOOD-CT-2004-513960 FLAVO).

An 11 year old female dog was admitted to Veterinary Clinical Department, Bologna University, with a clinical history of anorexia, constipation and ptyalism. Clinical findings included rectal temperature of 35,3°C, depression and jaundice. The dog was euthanasied and submitted for necroscopy to our Department. Gross changes included jaundice of skin, subcutis, sclerae and a non-patency of choledoch duct. The definitive diagnosis was jaundice caused by extra-hepatic cholestasis. Microscopical examination showed an hyperplastic epithelium forming intramural cysts of the gall bladder and of the extrahepatic bile duct until the duodenum. Unlike cases described in literature where cystic hyperplasia of gall bladder doesn’t give clinical evidence, the case here reported is peculiar because this pathology is responsible of an extra-hepatic jaundice syndrome.

Incarceration of liver tissue in a hernia of the umbilical cord is a rare occurrence. An incarceration of the gall bladder is even rarer. We report such a case in a newborn that had incarceration of both liver and gall bladder in to the umbilical cord.

This is the first part of a series of three articles on trimming instructions of rat and mouse protocol organs and tissues in regulatory type toxicity studies. It is based on the experience made in the European RITA and American NACAD working groups and is an extended revision of trimming guides published in 1995 (Bahnemann et al.). The optimum localization for tissue preparation, the sample size, the direction of sectioning and the number of sections to be prepared is described organ by organ. These descriptions are illustrated for each organ by a schematic drawing and a macro-photograph showing the plane of section as well as a low power view of the H&E stained slide demonstrating the optimum "end-product". This revision will improve the quality and efficiency of routine procedures and facilitate daily work in the histotechnical lab. It will promote intra- and inter-study reproducibility and comparability and thus lead to a further coherence within each study and improvement of the validity of historical control data.

Heterotopic pancreatic tissue in the gallbladder is a very uncommon lesion, which is an incidental finding in most cases. We report here, a case of an 18-year-old, post puerperal female, suffering from right upper quadrant abdominal pain with a clinical diagnosis of chronic cholecystitis, in whom heterotopic pancreatic tissue was found in the gall bladder.

Purpose: Objective of the study was to find out if there is any relation of number, size and type of gall stones and patient’s lipid profile with the occurrence of gall bladder carcinoma (GBC) as presence of gall stones is considered to be the most important risk factor for gall bladder cancer.Methods: 200 specimens of post-cholecystectomy gallbladder were studied. The number, size and type of stones and lipid profile were compared in all these cases. Gross as well as histopathological examination of gall bladders specimens was done.Results: 185 (92.5%) gall bladders were associated with gall stones. On histopathological examination, malignancy was found in 6 cases (3%) only and rest 194 cases (97%) revealed inflammatory/ non-neoplastic pathology. A statistically significant difference was observed in the number of stones in gall bladders with malignancy than those with benign lesions (P < 0.001). Similarly, a statistically significant difference was seen in terms of stone size between gallbladder cancer (GBC) cases and those with benign pathology (P < 0.005). Benign lesions of gall bladders were mostly associated with mixed type of stones whereas malignant cases were associated with pure cholesterol type of stones. No significant relation was found between the patient’s lipid profile and occurrence of gallbladder carcinoma (GBC) (p > 0.005). Conclusion: Thus we concluded that as the number, size and cholesterol gall stone increase the risk of gall bladder cancer also increases without any relation with lipid profile................................................Cite this article as:Narang S, Goyal P, Bal MS, Bandlish U, Goyal S.
