Ectopic gastric mucosa in the submucosa of the stomach: A case report.

Under normal circumstances, gastric mucosa only exists within the stomach. However, in certain situations, gastric mucosal tissue may undergo ectopia, commonly occurring in the esophagus and intestine, with rare occurrences within the stomach itself. A comprehensive literature review was performed to understand the distinct characteristics of ectopic gastric mucosa (EGM) in the stomach and investigate a rare incident of this disease, providing an in-depth analysis of the clinical, histopathologic, and differential diagnostic findings. The case was a 47-year-old man with acid reflux, heartburn, abdominal distension, and diarrhea (5-10 times daily) for >10 years. A gastroscope indicated a submucosal protuberance lesion in the gastric body that felt hard with biopsy forceps. A well-defined nodule under the mucosal muscle was revealed microscopically, composed of epithelial elements and no atypia. Immunohistochemical staining demonstrated similar EGM expression patterns compared with normal gastric mucosa. The present case report highlights the importance of accurate EGM diagnosis and understanding.

Anatomical dimensions of the lumbar dural sac predict the sensory block level of continuous epidural analgesia during labor.

BACKGROUND: The anatomical dimensions of the lumbar dural sac determine the sensory block level of spinal anesthesia; however, whether they show the same predictive value during continuous epidural anesthesia (CEA) remains undetermined. We designed the present study to verify the efficacy of the anatomical dimensions of the lumbar dural sac in predicting the sensory block level during labor analgesia. METHODS: A total of 122 parturients with singleton pregnancies requesting labor analgesia were included in this study. The lumbar dural sac diameter (DSD), lumbar dural sac length (DSL), lumbar dural sac surface area (DSA), and lumbar dural sac volume (DSV) were measured with an ultrasound color Doppler diagnostic apparatus. CEA was performed at the L2-L3 interspace. After epidural cannulation, an electronic infusion pump containing 0.08% ropivacaine and sufentanil 0.4 µg/ml was connected. The sensory block level was determined with alcohol-soaked cotton, a cotton swab, and a pinprick. The analgesic efficacy of CEA was determined with a visual analog scale (VAS). The parturients were divided into two groups, "ideal analgesia" and "nonideal analgesia," and the groups were compared by t test. Pearson's correlation was performed to evaluate the association between the anatomical dimensions of the lumbar dural sac and sensory block level. Multiple linear regression analysis was used to create a model for predicting the sensory block level. RESULTS: In the ideal analgesia group, the height, DSL, DSA, DSV and DSD were significantly smaller, and the body mass index (BMI) was significantly larger (P < 0.05). In addition, the DSL demonstrated the strongest correlation with the peak level of pain block (r = - 0.816, P < 0.0001; Fig. 2A), temperature block (r = - 0.874, P < 0.0001; Fig. 3A) and tactile block (r = - 0.727, P < 0.0001; Fig. 4A). Finally, the multiple linear regression analysis revealed that DSL and BMI contributed to predicting the peak sensory block level. CONCLUSION: In conclusion, our study shows that the sensory block level of CEA is higher when the DSL, DSA, DSV and DSD of puerperae are lower. DSL and BMI can be treated as predictors of the peak sensory block level in CEA during labor analgesia.

[Anti-injury effect of hydrogen-enriched water in a rat model of liver injury induced by aflatoxin B1].

The purpose of this study was to investigate the anti-injury effect and protective mechanism of hydrogen-enriched water in a rat model of acute liver injury induced by aflatoxin B1 (AFB1). Healthy male Sprague-Dawley (SD) rats were randomly divided into control group, model group (AFB1 group) and hydrogen-enriched water treatment group (AFB1+H2 group). The rat model of acute liver injury induced by AFB1 was established by single intragastric administration of AFB1 (2.0 mg/kg), and then the rats were treated with hydrogen-enriched water intragastrically. HE staining was used to observe the pathological changes of liver tissue. Blood samples were taken from vena cava to measure serum liver function indexes. Live tissue was sampled to detect malondialdehyde (MDA) and reduced glutathione (GSH) contents. Western blot was used to detect phosphorylation levels of MAPK signaling pathway proteins (ERK, JNK and p38 MAPK). The results showed that, compared with the AFB1 group, the AFB1+H2 group exhibited increased body weights, alleviated acute liver injury, decreased activities of serum glutamic-pyruvic transaminase and glutamic oxaloacetic transaminase, as well as total bilirubin level in the serum. Meanwhile, hydrogen-enriched water decreased MDA content and increased GSH content in liver tissue. AFB1-increased phosphorylation levels of ERK, JNK and p38 MAPK in liver tissue were down-regulated significantly by hydrogen-enriched water treatment. These results suggest that hydrogen-enriched water can alleviate liver injury induced by AFB1, and its mechanism may be related to the reduction of oxidative stress and the inhibition of MAPK signal transduction pathway activation.

Analysis of the causative factors related to earlier emulsification of silicone oil.

The aim of this study is to report and analyze the factors related with earlier occurrence of silicone oil (SO) emulsification in patients underwent pars plana vitrectomy and SO injection in our hospital. We retrospectively reviewed consecutive case series undergone both SO injection and removal in our hospital, and 182 ones were eligible. Possible related independent factors included: macula status (on/off), concomitant phacoemulsification with the surgery of SO tamponading, concomitant status of proliferative vitreoretinopathy, combined surgery of retinotomy, time to have emulsification (<6mo/≥6mo after primary SO injection), route of SO injection (anterior/posterior), lens status (aphakic/pseudophakic/phakic), anesthesia (local/general), brands and type of SO, with/without episcleral cryotherapy, with/without hypertension, with/without diabetes, with/without intraoperative use of triamcinolone acetonide. The study revealed that brand and type of SO was the significant factor related with earlier emulsification of SO. Further study was warranted to find out the underlying causes.

Role of transforming growth factor ß­1 in the pathogenesis of pelvic organ prolapse: A potential therapeutic target.

The present study aimed to reveal the metabolic alterations of the extracellular matrix (ECM) in uterosacral ligament (USL) with pelvic organ prolapse (POP) and to explore the role of transforming growth factor­ß1 (TGF­ß1) in pathogenesis of POP. For this purpse, 60 participants who underwent hysterectomy for benign indications were enrolled, 30 of which had symptomatic POP (grade II, III or IV) and composed the POP group, and the other 30 had asymptomatic POP (grade I or less) and served as the controls. Collagen fibers, elastin,matrix metalloproteinase (MMP)­2/9, tissue inhibitor of matrix metalloproteinases (TIMP)­2 and TGF­ß1 were examined by Masson's trichrome staining, immunohistochemistry and RT-qPCR using USL biopsies. In vitro, human USL fibroblasts (hUSLFs) were primary cultured, pre-treated with recombinant TGF­ß1 (0, 5, or 10 ng/ml) and then subjected to cyclic mechanical stretching (CMS; 0 or 5,333 µÎµ strain). Changes in the expression levels of collagen type I/III, elastin, TIMP­2, MMP­2/9 and Smad were detected. Our results revealed that at the tissue level, the expression of collagen fibers, elastin, TIMP­2 and TGF­ß1 was significantly reduced in the POP group, while the activities of MMP­2/9 were significantly upregulated, compared with the control group. Statistical analysis indicated that the mRNA expression of TGF­ß1 inversely correlated with the severity of POP partially. Our in vitro experimental data demonstrated that a CMS of 5333 µÎµ strain promoted the degradation of ECM proteins, inhibited the synthesis of TIMP­2, and upregulated the proteolytic activities of MMP­2/9. Pre-treatment with TGF­ß1 attenuated the loss of ECM by stimulating the synthesis of TIMP­2 and inhibiting the activities of MMP­2/9 through the TGF­ß1/Smad3 signaling pathway. On the whole, our data indicate that the reduced anabolism and increased catabolism of ECM proteins in USL are the pathological characteristics of POP. TGF­ß1 not only has a specific value in predicting the severity of POP, but should also be considered as a novel therapeutic target for POP.

Role of mechanical strain-activated PI3K/Akt signaling pathway in pelvic organ prolapse.

Mechanical loading on pelvic supports contributes to pelvic organ prolapse (POP). However, the underlying mechanisms remain to be elucidated. Our previous study identified that mechanical strain induced oxidative stress (OS) and promoted apoptosis and senescence in pelvic support fibroblasts. The aim of the present study is to investigate the molecular signaling pathway linking mechanical force with POP. Using a four­point bending device, human uterosacral ligament fibroblasts (hUSLF) were exposed to mechanical tensile strain at a frequency of 0.3 Hz and intensity of 5333 µÎµ, in the presence or absence of LY294002. The applied mechanical strain on hUSLF resulted in apoptosis and senescence, and decreased expression of procollagen type I α1. Mechanical strain activated phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)/Akt signaling and resulted in downregulated expression of glutathione peroxidase 1 and Mn­superoxide dismutase, and accumulation of intracellular reactive oxygen species. These effects were blocked by administration of LY294002. Furthermore, it was demonstrated that PI3K/Akt was activated in the uterosacral ligaments of POP patients, and that OS was increased and collagen type I production reduced. The results from the present study suggest that mechanical strain promotes apoptosis and senescence, and reduces collagen type I production via activation of PI3K/Akt-mediated OS signaling pathway in hUSLF. This process may be involved in the pathogenesis of POP as it results in relaxation and dysfunction of pelvic supports.

First-principles investigations of transition-metal doped bilayer WS2.

By performing first-principles calculations, we have studied the structural, electronic and magnetic properties of transition-metal (TM) (Mn, Fe, Co, Ni) doped bilayer WS2 in both the AA and AB configurations. We have examined three probable interlayer doping positions, and found that the doped TM atoms prefer to stay below the S atoms. The TM atoms are covalently bound to the upper layer and lower layer S atoms with binding energies ranging from -0.74 to -1.72 eV for the AA configuration and from -0.69 to -1.80 eV for the AB configuration. Our calculations indicate that all the studied configurations are still semiconductors although the corresponding band gaps reduce a lot, except for the Fe-doped AA configuration which changes to a semi-metal with one spin state cross over at the Fermi level. Additional, our calculations indicate that Mn, Fe and Co-doping induces magnetism in both the AA and AB configurations. More importantly, a high spin polarization of 100% at the Fermi level is achieved in the Co-doped AA configuration and the Mn and Fe-doped AB configurations, which implies the potential for application in spintronic devices.

Collagen metabolic disorder induced by oxidative stress in human uterosacral ligament­derived fibroblasts: A possible pathophysiological mechanism in pelvic organ prolapse.

Pelvic organ prolapse (POP) is a global health problem, for which the pathophysiological mechanism remains to be fully elucidated. The loss of extracellular matrix protein has been considered to be the most important molecular basis facilitating the development of POP. Oxidative stress (OS) is a well­recognized mechanism involved in fiber metabolic disorders. The present study aimed to clarify whether OS exists in the uterosacral ligament (USL) with POP, and to investigate the precise role of OS in collagen metabolism in human USL fibroblasts (hUSLFs). In the present study, 8­hydroxyguanosine (8­OHdG) and 4 hydroxynonenal (4­HNE), as oxidative biomarkers, were examined by immunohistochemistry to evaluate oxidative injury in USL sections in POP (n=20) and non­POP (n=20) groups. The primary cultured hUSLFs were treated with exogenous H2O2 to establish an original OS cell model, in which the expression levels of collagen, type 1, α1 (COL1A1), matrix metalloproteinase (MMP)­2, tissue inhibitor of metalloproteinase (TIMP)­2 and transforming growth factor (TGF)­ß1 were evaluated by western blot and reverse transcription­quantitative polymerase chain reaction analyses. The results showed that the expression levels of 8­OHdG and 4­HNE in the POP group were significantly higher, compared with those in the control group. Collagen metabolism was regulated by H2O2 exposure in a concentration­dependent manner, in which lower concentrations of H2O2 (0.1­0.2 mM) stimulated the anabolism of COL1A1, whereas a higher concentration (0.4 mM) promoted catabolism. The expression levels of MMP­2, TIMP­2 and TGF­ß1 exhibited corresponding changes with the OS levels. These results suggested that OS may be involved in the pathophysiology of POP by contributing to collagen metabolic disorder in a severity­dependent manner in hUSLFs, possibly through the regulation of MMPs, TIMPs and TGF­ß1 indirectly.

Ferromagnetism in Transitional Metal-Doped MoS2 Monolayer.

Manipulating electronic and magnetic properties of two-dimensional (2D) transitional-metal dichalcogenides (TMDs) MX2 by doping has raised a lot of attention recently. By performing the first-principles calculations, we have investigated the structural, electronic, and magnetic properties of transitional metal (TM)-doped MoS2 at low and high impurity concentrations. Our calculation result indicates that the five elements of V-, Mn-, Fe-, Co-, and Cu-doped monolayer MoS2 at low impurity concentration all give rise to the good diluted magnetic semiconductors. By studying various configurations with different TM-TM separations, we found that the impurity atoms prefer to stay together in the nearest neighboring (NN) configuration, in which the doped TM atoms are FM coupling except for Fe doping at 12 % concentration. For V, Mn, and Fe doping, the total magnetic moment is smaller than the local magnetic moment of the dopants because the induced spins on the nearby host atoms are antiparallel to that of the doped atoms. In contrast, Co and Cu doping both give the higher total magnetic moment. Especially, Cu doping induces strong ferromagnetism relative to the local spins. However, the atomic structures of Co- and Cu-doped MoS2 deviate from the original prismatic configuration, and the magnetic moments of the doped systems decrease at 12 % impurity concentration although both elements give higher magnetic moments at 8 % impurity concentration. Our calculations indicate that V and Mn are promising candidates for engineering and manipulating the magnetism of the 2D TMDs.

Assessment of immune cells and function of the residual spleen after subtotal splenectomy due to splenomegaly in cirrhotic patients.

BACKGROUND: The spleen is thought to be central in regulating the immune system, a metabolic asset involved in endocrine function. Overwhelming postsplenectomy infection leads to a mortality rate of up to 50%. However, there is still controversy on performing subtotal splenectomy as treatment of splenomegaly due to portal hypertension in cirrhotic patients. In the present study, immunocytes and the indexes of splenic size, hemodynamics, hematology and immunology in the residual spleen were analyzed to support subtotal splenectomy due to splenomegaly. RESULTS: In residual spleen, T lymphocytes mainly were focal aggregation in the periarterial lymphatic sheath. While B lymphocytes densely distributed in splenic corpuscle. In red pulp, macrophages were equally distributed in the xsplenic cord and adhered to the wall of splenic sinus with high density. The number of unit area T and B lymphocytes of splenic corpuscle and marginal zone as well as macrophages of red pulp were obviously increased in the residual spleen, while the number of macrophages didn't be changed among the three groups in white pulp. While there were some beneficial changes (i.e., Counts of platelet and leucocyte as well as serum proportion of CD3+ T cells, CD4+ T cells, CD8+ T cells were increased markedly; serum levels of M-CSF and GM-CSF were decreased significantly; The proportion of granulocyte, erythrocyte, megakaryocyte in bone marrow were changed obviously; But serum IgA, IgM, IgG, Tuftsin level, there was no significant difference; splenic artery flow volume, portal venous diameter and portal venous flow volume, a significant difference was observed in residual spleen) in the clinical indices. CONCLUSION: After subtotal splenectomy with splenomegaly due to portal hypertension in cirrhotic patients, the number of unit area T and B lymphocytes, and MØ in red pulp of residual spleen increased significantly. However, whether increase of T, B lymphocytes and MØs in residual splenic tissue can enhance the immune function of the spleen, still need further research to confirm.

Mechanistic insights of sulfur mustard-induced acute tracheal injury in rats.

Sulfur mustard (SM) is believed to be a major threat to civilian populations because of the persistent asymmetric threat by nonstate actors, such as terrorist groups, the ease of synthesis and handling, and the risk of theft from stockpiles. The purpose of this study was to establish mechanisms of acute tracheal injury in rats induced by SM using histopathologic, immunohistochemical, and biochemical parameters. Male rats (Sprague-Dawley) were anesthetized, intratracheally intubated, and exposed to 2 mg/kg of SM. Animals were euthanized 6-, 24-, 48-, and 72-hour postexposure, and intracavitary blood samples from the heart and tracheal tissues were collected. Exposure of rats to SM resulted in rapid tracheal injury, including tracheal epithelial cell shedding, focal ulceration, and abundant lymphocyte invasion of the submucosa. There was also evidence of a large number of apoptotic cells in the epithelium and submucosa, the serum levels of tumor necrosis factor α, interleukin 1ß (IL) 1ß, IL-6, and γ-glutamyl transferase peaked at 24 hours, and the serum levels of lactate dehydrogenase, glutathione peroxidase, and thiobarbituric acid reactive substance peaked at 6 hours. The SM exposure also resulted in a loss of the cellular membrane, leakage of cytoplasm, fuzzy mitochondrial cristae, medullary changes in ciliated and goblet cells, and the nuclear chromatin appeared marginated in basal cells and fibroblasts. The results in the propylene glycol group were the same as the control group. These data demonstrated the histologic changes, inflammatory reactions, apoptosis, oxidative stress, and DNA damage following SM (2 mg/kg)-induced acute tracheal injury; the severity of changes was time dependent.

Assessment of the infiltration of inflammatory cells in the walls of thrombotic varicose veins.

The purpose of this study is to describe the infiltration of mast cells as well as T and B cells in the walls of thrombotic varicose great saphenous veins. Sections were obtained from venous segments of patients with varicose veins and stained with toluidine blue for mast cells, while immunohistochemistry for T cells (using CD45RO antibody) and B cells (CD20) was analyzed using light microscopy after staining. The number of mast cells, T, and B cells observed in thrombotic varicose veins was 1.925 ± 1.203, 72.038 ± 34.707, and 19.519 ± 9.899, respectively. In varicose veins, the corresponding values were 0.265 ± 0.099, 0.600 ± 0.432, and 0.488 ± 0.400. Significantly higher number of mast cells, T cells, and B cells were observed in thrombotic varicose veins compared with control veins. A significant difference was not observed between the varicose group and control group. Thrombi in varicose veins can induce infiltration of mast cells, T cells, and B cells, which may be involved in the remodeling of venous walls.

[Study on the expression and the role of macrophage migration inhibitory factor in the brain of neonatal rats with hypoxia-ischemia brain damage].

OBJECTIVE: To explore the expression of macrophage migration inhibitory factor (MIF), phosphorylated extracellular signal regulated kinases 1/2 (pERK1/2), matrix metalloproteinase-9 (MMP-9) in brain and the correlations with cerebral edema after hypoxia-ischemia brain damage (HIBD). METHODS: 144 seven-day-old SD rats were randomly dividend into three groups that was the sham operation group, HIBD group and intervention group with anti-MIF. Each group were executed in 1 h, 6 h, 12 h and 24 h, 3 d, and 7 d. The expression of MIF, MMP-9 protein in the right cerebral cortex was detected with immunohistochemistry methods, the relative content of pERK1/2 was detected with Western blot and the water content of brain was evaluated with dry-wet method. RESULTS: Comparing with the sham group the expression of MIF in the HIBD group began to increase on 1 h, and peaked on 24 h (P < 0.05), and MMP-9 began to express on 6 h, and also peaked on 24 h (P < 0.05), while pERK1/2 expressed rapidly to peak on 1 h, and quickly decreased on 6 h, and began to increase on 12 h and reached the peak again on 24 h (P < 0.05). Being treated with hypoxia-ischemia, the water content of brain began to increase on 6 h and peaked on 3 d (P < 0.05). And comparing with HIBD group, the expressions of MIF, pERK1/2, MMP-9 and the water contents were decreased obviously in the anti-MIF group (P < 0.05). CONCLUSION: The increased expression of MIF in the neonatal rats with hypoxia-ischemia brain damage maybe via activing the ERK1/2 ways to induce MMP-9 expressand leading to cerebral edema.

[Expression of iNOS protein and gliacyte apoptosis in neonatal rats with white matter damage].

OBJECTIVE: Inducible nitric oxide synthase (iNOS) is a main rate-limiting enzyme resulting in over-production of nitric oxide following hypoxia-ischemia (HI). The aim of this study was to observe the expression of iNOS protein and gliacyte apoptosis in the brains of premature rats after HI, in order to explore possible relationships of iNOS with white matter damage (WMD). METHODS: One hundred and twelve 2-day-old premature rats were randomly subjected to right carotid ligation followed by 4 hrs hypoxic stress (WMD group) or sham operation (control group). The pups were sacrificed at 1, 3, 6, 12 hrs, and 1, 3 and 7 days after HI. Immunohistochemical technique was applied to determine the iNOS expression in periventricular white matter tissues. Gliacyte apoptosis was detected in these tissues by TUNEL. RESULTS: Compared with the control group, iNOS expression began to increase 1 hr after HI and reached the peak 1 day after HI in the WMD group. Gliacyte apoptosis increased 1 hr after HI and peaked 1 day after HI in the WMD group compared with the control group. CONCLUSIONS: In the neonatal rats with WMD, the expression of iNOS may be involved in the ischemic cellular events including apoptosis, and plays a role in the pathophysiological process of WMD.

The mechanism of Cordyceps sinensis and strontium in prevention of osteoporosis in rats.

The effects of Cordyceps sinensis (Caterpillar fungus) and strontium ranelate on ovariectomized osteopenic rats was studied in this paper. After the rats were treated orally with C. sinensis, strontium, and C. sinensis rich in strontium ranelate (CSS) respectively, serum alkaline phosphatase (ALP), tartarate-resistant acid phosphatase (TRAP), serum osteocalcin (OC), homocysteine, C-terminal crosslinked telopeptides of collagen type I (CTX), estradiol, and interferon-gamma (IFN-γ) level were examined. The beneficial effects of CSS on improvement of osteoporosis in rats were attributable mainly to decrease ALP activity, TRAP activity, CTX level, and IFN-γ level. At the same time, CSS also increase the OC and estradiol level in ovariectomized osteopenic rats. This study demonstrates the value of C. sinensis rich in strontium ranelate in the management of postmenopausal osteoporosis in humans.

[hTERT gene expression in children with beta-thalassemia major].

OBJECTIVE: Human telomerase reverse transcriptase (hTERT) is a rate-limiting enzyme which dictates the activity of human telomerase and thus decides the life span of cells. The aim of this study was to explore the expression of hTERT in bone marrow from children with beta-thalassemia major and the relationship between the expression of hTERT and hemoglobin levels. METHODS: Multiple allele specific polymerase chain reaction (MASPCR) was used for targeted DNA amplification and gene mutation analysis of beta-thalassemia. hTERT mRNA expression in bone marrow was examined using real-time reverse transcription polymerase chain reaction (RT-PCR) analysis in 29 children with beta-thalassemia major, in 10 children with agranulocytosis and in K562 cell line. The hemoglobin levels in peripheral blood were measured. The relationship between hTERT expression and hemoglobin levels was evaluated by the Spearman test in the beta-thalassemia major group. RESULTS: hTERT mRNA expression significantly increased in bone marrow from children with beta-thalassemia major compared with that from children with agranulocytosis (0.2928+/- 0.0838 vs 0.0993+/- 0.0336; P<0.01), but was significantly lower than that in K562 cell line (0.8291+/- 0.0908) (P<0.01). A significantly inverse correlation was found between hTERT mRNA expression and hemoglobin levels (r=-0.841, P<0.01). CONCLUSIONS: A low hemoglobin concentration might contribute to the up-regulation of marrow hTERT expression in children with beta-thalassemia major.

Rupture of dissecting aneurysm: autopsy study of 3 cases

Dissecting aneurysm (DA); more appropriately termed dissecting haematoma; is the separation of layers of the vascular wall by a column of blood from the lumen. Dissecting aneurysms of the aorta differ from atherosclerotic and syphilitic aneurysms in that they are not usually associated with marked dilatation of the aorta. DA of the aorta; irrespective of the etiology; if untreated; are associated with a rapidly fatal outcome in 75 per cent to 90 per cent of the patients. Death from DA most often results from rupture. Rupture sites frequently associated with a fatal outcome include the pericardial sac leading to acute haemopericardium; the mediastinum; the left pleural cavity and the retroperitoneum. Autopsy study on three cases of sudden death revealed haemopericardium as a result of rupture of DA of the ascending aorta. One case was seen in a young individual with Marfan's syndrome and two were present in elderly individuals with hypertension. The etiopathogenesis; presentation; outcome and management of this fatal complication is discussed

Trend of cervical cancer in Seychelles

A 10-year study of all cervical biopsies and hysterectomy specimens received in the Department of Pathology; Victoria Hospital was carried out. Representative punch biopsies of cervix; either colposcope guided; or taken from non-staining areas of cervix following application of Schiller's iodine paint; and fixed in 10 per cent formal saline in the theatre were received in the pathology department. During the ten year period (1983-1992); 175 cases of cervical cancer were detected. Of these; 66 cases were at the CIN 3 stage; 28 were CIN 3 with microinvasion; 69 cases showed frank infiltrating squamos cell carcinoma; 11 exhibited adenocarcinoma and 1 had adenosquamous features

Non-cancerous breast lesions in Seychelles : an appraisal

In recent years there has been an increase in the number of both cancerous and non-cancerous lesions of the breast seen by doctors in Seychelles. The cancer registry held by the department of pathology reveals that 3 cases of breast cancer were reported in 1989; 4 in 1990; 6 in 1991 and 11 in 1992. Department of pathology records also reveal that 36 cases of non-cancerous breast lesions were reported in 1989; 30 in 1990; 48 in 1991 and 49 in 1992. These increases call for the development of a protocol for the management of all the palpable; nodular swellings of the breast; irrespective of marital status; age; parity and use of oral contraceptives
