A 54-year-old man with a 24-year history of androgenetic alopecia was referred to the Department of Dermatological Sciences with follicular inflammatory lesions leading to scleroatrophy in the vertex region (Figure 1) of 1-year duration. These lesions appeared a year ago. There was no previous history of this condition. On examination, the patient showed confluent infiltrative follicular lesions on the frontoparietal and occipital scalp (Figure 2). Some lesions evolved into erosions that developed in ivory white scleroatrophy within weeks. These lesions were localized both in and outside of are as affected by alopecia androgenetica and were associated with mild pruritus. Histopathologic examination, performed on an early lesion of the vertex, documented a mild thinning of follicular epithelium associated with an intense lymphohistiocytic perifollicular infiltrate. The damage of the basal cell layer was limited to the follicle, while epidermis was intact. In particular, follicular keratinocytes under the isthmus showed a very intense degeneration exactly where the infiltrate was the most prominent. The damage of the hair sheath was under the isthmus and involved the lower portions of the follicles (including the hair bulbs). The inflammatory infiltrate was exclusively represented by perifollicular lymphohistiocytes. Finally, a connective fibrotic shell with numerous fibroblasts formed a sheath around the atrophic follicle (Figure 3). Results of laboratory investigations (including complete blood cell counts, basal thyroid-stimulating hormone, C-reactive protein, serum ferritin levels, B and C hepatitis markers, antinuclear antibodies, and cultural examinations) were negative.We diagnosed the patient with fibrosing alopecia in a pattern distribution.

A 34-year-old woman developed bilateral optic neuritis 2 weeks after the onset of acute hepatitis C. The strong temporal relationship between the initial clinical manifestations of hepatitis C and the development of optic neuritis provides a basis for thinking that the hepatitis caused the optic neuritis After corticosteroid treatment, the optic neuropathy markedly improved but left behind retinal nerve fiber thinning, as measured by optical coherence tomography, and optic disc pallor. Optic neuritis has been reported in conjunction with hepatitis A and B but not with hepatitis C.

A 47-year-old man was admitted with four months history of pain upper central abdomen associated with passage of 3-4 loose watery stools per day. Abdominal examination revealed soft abdomen with mild tenderness in the para-umbilical region. There was associated hepatomegaly. His Hb% was low, liver and renal functions were deranged. Upper GI endoscopy revealed antral ulcer, and colonoscopy revealed a caecal ulcer, which were biopsied. Liver biopsy was also done. Histopathology report showed evidence of inflammatory colitis and chronic hepatitis, so a diagnosis of inflammatory bowel disease with autoimmune hepatitis was made. He was negative for HIV and hepatitis serology. He was given long list of medicine including steroids but the symptoms did not improve. Two months after admission he developed severe abdominal pain associated with distension. The X-Ray chest revealed pneumoperitoneum and laparotomy was carried out which revealed a small perforation in terminal ileum associated with multiple circular indurated areas ranging from few mm to 1.5 Cm in size with central thinning spread over distal half of small gut and enlarged mesenteric lymph nodes. The biopsy of perforated area revealed cytomegaloviral enteritis. Postoperatively patient developed ARDS and died on 13th postoperative day.

Peripheral ulcerative keratitis (PUK) is a sight-threatening condition characterized by an epithelial defect, crescent-shaped stromal inflammation, and progressive stromal thinning. Peripheral ulcerative keratitis as a purely inflammatory entity is most commonly associated with collagen vascular diseases, including rheumatoid arthritis, polyarteritis nodosa, Wegener granulomatosis, systemic lupus erythematosus, and relapsing polychondritis. PUK can also be associated with infectious and inflammatory conditions such as hepatitis, syphilis, herpes simplex keratitis, fungal keratitis, Mooren ulcer, and marginal keratitis. We describe a case report of PUK associated with the inflammatory condition of sarcoidosis.

Slaughterhouse condemnation of broiler chickens results from identification of polymorphic pathological conditions during meat inspection from arrival and on the slaughter line. While conditions that result in condemnation are multifactorial, identification of factors that are common for a number of categories could be valuable for developing strategies to reduce total condemnation. This study aimed to identify those condemnation categories that were most common in batches of broiler chickens and to determine and compare associated risk factors. In the first step, retrospective meat inspection records for 55,918 broiler batches from one large broiler integrator for 2015-2017 were used for association rules analysis. Results identified a network of nine associated condemnation categories: whole carcass condemnation for ascites, abnormal colour, perihepatitis, cellulitis, hard breast, tumours and dead on arrival, and liver only and heart only most often associated with hepatitis and pericarditis, respectively. Secondly, a longitudinal study collected data on 109 explanatory variables from broiler parental flocks to slaughterhouse characteristics between January 2015 and December 2017. Condemnation outcome data were obtained from meat inspection records for 539 broiler batches participating in the study. Parental flock-, rearing farm-, shed- and transport-level risk factors were assessed for each outcome using mixed-effects multivariable Poisson regression including shed and farm as random effects. A Poisson regression tree method was used as the first step to identify variables most relevant for analysis and comparison across the outcomes. No single production factor was associated with all nine of the condemnation outcomes investigated in this study, although some were shared across multiple outcomes: age of parental flock at time of lay, flock-level Campylobacter spp. frequency, broiler chick weight at seven days of age, weight at slaughter, type of broiler removal (i.e. thinning, final depopulation), catcher team, number of birds per transport crate, slaughterhouse shift number, and type of slaughterhouse line. Broiler chickens removed during final depopulation were at greatest risk of condemnation. Condemnation rates for cellulitis and tumours were found to be higher in broilers inspected by night shift at the slaughterhouse. Discovery of an apparent protective effect of a higher number of broilers per transport crate was unexpected. These findings provide information for the broiler industry on production chain factors that might be amenable to targeted intervention to improve future efforts for control of condemnation.

The foundation of the condemnation practices in Post-Mortem Inspection (PMI) of poultry should be based on up-to-date scientific evidence about the cause of infection and hence whether the lesions observed are of food safety, animal health or welfare concerns. This study aimed to investigate the association between meat inspection codes, footpad lesions, and thinning of flocks in Danish broiler production. The data set was based on the delivery of chicken flocks to one of the two larger chicken slaughterhouses in Denmark, representing 71 farms, 174 houses, and 4,068 flocks over three years from January 2016 to December 2018. Post-mortem condemnation data of slaughtered chickens recorded and stored in the Danish Quality Assurance System (KIK) database was used in the study. Five potentially causal models were developed to investigate whether there was an association between dermatitis, arthritis, systemic infection, emaciation, mortality and possible explaining factors` (footpad lesion, age at slaughter, scratches, ascites, systemic infection and thinning of the flock). These five ecological logistic regression models were analyzed with the three levels: farm, house, and flock. Data from a total number of 126,137,002 (N) slaughtered chickens recorded in KIK databases were used for modeling and analyses. The prevalence of condemned carcasses was 1.1 % (n = 1,420,812). Overall, 12 individual reasons for condemnation of carcasses were recorded. The most frequently observed reason for condemnation was skin disease (scratches and dermatitis) with a prevalence of 0.5 %. Prevalence of ascites was 0.2 %, discoloration 0.09 %, emaciation 0.09 %, hepatitis 0.09 % and arthritis 0.07 %. In the first model, dermatitis was shown to be positively associated with age at slaughter with an OR = 1.04 (CI95 %: 1.02-1.05), while arthritis was considered an intervening variable. Moreover, there was a small protective effect of thinning of the flock for first and second delivery. There was a positive association between arthritis and age at the time of slaughter with an OR = 1.13 (CI95 %: 1.12-1.15). Systemic infections were associated with scratches with an OR = 24.5 (CI95 %: 16.6-36.3) and footpad lesions with an OR = 1.007 (CI95 %: 1.006-1.008). Further modelling of emaciation and mortality was not considered because of unbalanced groups in the data probably caused by the fact that some condemnation codes were rare. We observed that the most common causal factors of condemnation in the systemic infection models were scratches and footpad lesion, therefore preventing and controlling such lesions could reduce losses. Specific management and environmental etiological factors of the main infections causing condemnation in Danish broilers should be determined.
