Background. Day to day advances in the fields of radiology like sonography and CT need to revive interest in the cadaveric study of morphological features of liver, as the accessory fissures are a potential source of diagnostic errors. Accessory fissures vary from single to multiple over different parts of the liver. Aim. In the present study the morphological features of human liver specimens were evaluated by macroscopic examination and morphometric analysis. Methods. The study was conducted on 58 specimens obtained from cadavers utilized for routine dissection for medical undergraduates from the year 2004 to 2012 in the Anatomy Department of MIMS Medical College. Results. In the present study the livers as described in the established anatomical literature with normal surfaces, fissures, and borders were considered normal. Out of the 58 specimens, 24 were normal without any accessory fissures or lobes and with normal contours.

A case report by Sen in 1887 at the Calcutta Medical Association is, so far as I am aware, the first contribution to the literature on the subject, and he has described the disease as " a peculiar enlargement of the liver in young children only, both male and female, without any enlarge- ment of the spleen and associated with low fever, gradual emaciation, loss of appetite, sallow complexion and very slight jaundice, but not in all" In the discussion that followed the case report, Ghose, Coomer, Rakhaldas Ghose, Devendranath Dey, Bannerjee, Ahmed, Gibbons, Mcleod and Birch participated and the conclusions arrived at were as follows :-- (i) Infantile Cirrhosis of the liver was undoubtedly a peculiar disease found only amongst Indian children of the rich and the poor families alike. 310 Infantile Cirrhosis of tke Liver 311 (ii) The probable causative factors were the over-feeding of the children and bad hygenic conditions in which they were brought up.

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria.

  • Difficult Gallbladder Surgery, Improving Patient Outcomes Through Appropriate Surgical Decisions
    e text] Difficult Gallbladder Surgery, Improving Patient Outcomes Through Appropriate Surgical Decisions. P. G Jani1, H. Gill 2, V. Kotecha3 1.Associate professor, Department of Surgery University of Nairobi 2Fellow of college of surgeons South Africa, Surgeon Groote Schuur Hospital 3M.D, Resident Department of Surgery University of Nairobi Correspondence to: Pankaj G. Jani. Email: [email protected] Background: Cholecystectomy is becoming a common operation in Africa. The right upper quadrant is regarded by many as the most difficult area of the abdomen because of the variable anatomy, small sized ducts and the irritant nature of bile. The fact that patients present late also adds to the difficulty with identification of structures in this area. A good working knowledge of the incidence and types of anatomical variations is key to a safe cholecystectomy. About 50% of patients presenting with gallbladder pathology show a significant anatomical variations. This study aimed to improve awareness amongst surgeons, both consultants and those in training to improve patient outcomes with gall bladder pathology. Case presentations: Four patients who had re-do surgeries at three different private hospitals in Nairobi are presented and discussed. None of the primary surgery in the four cases was done any of the authors. The re-do surgery in the four cases was performed by the principal author. The four patients respectively had a bile duct injury post open cholecystectomy, cholecystostomy done for gall bladder empyema, a stricture from a previous biliary-enteric anastomosis and obstructive jaundice from chronic pancreatitis. Conclusion: The large number of variations in the anatomic structure of biliary tree imposes an imperative need for surgeons to have an adequate knowledge and understanding of those variations, in order to control the safety of the surgical procedure in this field.

  • The Short History of Gastroenterology
    JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY 2003, 54, S3, 921 www.jpp.krakow.pl A. RÓDKA THE SHORT HISTORY OF GASTROENTEROLOGY Department of History of Medicine, Jagiellonian University Medical College Cracow, Poland In this paper research on the stomach and bowel physiology is presented in a historical perspective. The author tries to show how digestive processes were interpreted by the ancients and how they tried to adjust them to the dominating humoral theory of disease. It is pointed out that the breakthrough which created a new way of understanding of the function of the digestive system was made by Andreas Vesalius and his modern model of anatomy. The meaning of acceptance of chemical processes in digestion by iatrochemics representatives in XVII century is shown. Physiological research in XIX century, which decided about a rapid development of physiology, especially the physiology of the gastrointestinal tract, is discussed. Experiments were performed by all main representatives of this discipline: Claude Bernard, Jan Ewangelista Purkynì, Rudolph Heidenhain and especially Ivan Pavlov, who, thanks to the discoveries in the secretion physiology, explained basic functions of the central nervous system. The XX century was dominated by the research showing the important role of the endocrine system and biological agents in the regulation of secretion and motility of the digestive system. The following discoveries are discussed: Ernest Sterling (secretin), John Edkins (gastrin) and André Latarjet and Lester Dragstedt (acetylcholine). It is underlined that Polish scientists play an important role in the development of the gastroenterological science - among others; Walery Jaworski, who made a historical suggestion about the role of the spiral bacteria in etiopathogenesis of the peptic ulcer, Leon Popielski, who stated the stimulating influence of histamine on the stomach acid secretion, Julian Walawski, who discovered enterogastrons - hormones decreasing secretion.

ON THE STAGES AND FORMS OF SYPHILIS WITH MORE ESPECIAL REFERENCE TO THE HEPATIC MANIFESTATIONS OF THE DISEASE. 1 BY J. G. Adami, M.A., M.D., F.R.S.E., Professor of Pathology, McGill University, Montreal. It is remarkable how during all these centuries, syphilis has remained sharply distinguished from all other forms of human disease, constituting a class apart. There are many other contagious maladies, not a few chronic infectious disorders, and, now-a-days, we are able to group these together ; we can recognise common principles govern- ing their course and effects upon the organism, and can see, or think we see, a common principle underlying the morbid changes in one or other tissue from the onset of the disease to its culmination—a prin- ciple identical in the infant and in the aged. So we can with syphilis —only habitually we do not. We treat and regard it as a something distinct. Take for instance that disease which in its chronicity as in the lesions which characterise it, most closely resembles syphilis—tuber- culosis. From the onset to the end, at every stage, from the primary lesion to the most extensive generalisation ofthe process, we see one morbid change at work, namely, the focal multiplication of the bacilli leading to the development of tubercles.

Hepatogenesis commence at Fourth week of Intrauterine life by proliferation of endodermal diverticulam at the ventral aspect of the junction between Foregut and mid gut into the septum transversum where it divides into Pars Hepatica and Pars Cystica forms liver and gall bladder respectively. On seventh week of fetal development Pars hepatica differentiates into clusters of liver parenchyma in which billiary capillaries emerges for delivery of its secretions. The trunk of hepatic buds persists as common bile duct and its two branches were right and left hepatic ducts. Haemopoeitic cells, Kuffer cells, Capsule and fibroareolar tissue derived from mesoderm of septum transversum. Fibroblast Growth Factor 2 (FGF2) secreted by cardiac mesoderm induces the development of hepatic bud which generates hepatoblasts, intending the formation of hepatocytes.
