Lead is a well known environmental and reproductive toxicant. This study was designed to evaluate the blood lead levels in pregnant women in Nnewi, Anambra State, South Eastern Nigeria. A total of 100 apparently healthy subjects comprising of 75 pregnant women and 25 non-pregnant women (control) aged between 18 and 45 years were recruited for the study. Thereafter, 2mls of blood sample was collected into EDTA container for the estimation of lead concentration using atomic absorption spectrophotometric method. A structured questionnaire was used in obtaining relevant data for age, dietary and lifestyle patterns of subjects. The result showed a significantly higher lead level in pregnant women compared with control group (p=0.000). Also, the mean blood lead level differed significantly between the first and second trimester as well as between first and third trimesters of pregnancy (p<0.05), but values obtained were similar between second and third trimesters of gestation (p>0.05) respectively. This study further revealed significantly higher blood levels in pregnant women that consume caffeine, animals killed by ammunition, and food items as well as in pregnant women that smokes (p<0.05). Also, blood lead level was significantly elevated in pregnant women that used well and piped water respectively (p<0.05). Therefore, there is need to avoid avenues of lead exposures in pregnancy in order to sustain the low blood level recorded in this study and hence, limit the potential adverse implications of lead exposures.

Temporomandibular ankylosis is defined as a permanent constriction of the temporomandibular joint. It can be an articular or juxta-articular origin, and includes various pathologies. We report here an unusual cause of temporo mandibular ankylosis which is an osteochondroma diagnosed by an anatomopathological study of the bone block. A 16-year-old patient who consults for a difficulty in opening the mouth. The clinical examination was without particularities. The cranian scan revealed the presence of a bony block at the right temporo mandibular joint with almost complete disappearance of the joint space.It was the histological examination of the osseous block that led to the diagnosis of osteochondroma.

To evaluate the serum lactic dehydrogenase (LDH) level as a marker of severity of preeclampsia. Antenatal mothers without complications were taken as controls and women with preeclampsia taken as cases. They were evaluated for serum LDH levels. All enrolled women were followed till delivery and their course of pregnancy and fetal outcome were noted. Mean value of LDH in the control group was 395.16+ 92.54IU/L. The LDH level in non severe type of preeclampsia was 566+ 219IU/L and in severe type of preeclampsia was >600 IU/L where it was highly significant (p<0.001). Antenatal complications and neonatal complications were 25% more in severe preeclampsia where serum LDH levels were >800IU/L. The severity of maternal and fetal complications was correlated well with increased LDH levels in preeclampsia.

Acquired Immune Deficiency Syndrome (AIDS) is caused by lymphotropic retrovirus which was first recognised in 1981 and subsequently HIV was discovered in 1983. HIV infection causes derangement in hematopoietic system which directly results in lymphopenia with the progression of disease and leads to decrease in CD4 lymphocytes, which is directly related to prognosis of disease. It is said that other blood cells may also be deranged due to HIV infection leading to anemia, neutropenia or thrombocytopenia. The purpose of this study was to assess various haematological various haematological changes in HIV patients and to correlate the finding with CD4 counts. A total of 50 seropositive patients were studied over a period of 1 year. All patients diagnosed as HIV 1 and 2 were included in the study. Patients with no haematological study or CD4 count were excluded from the study. The hematological parameters included under this study were – Hemoglobin, Total Leucocyte count, Absolute Lymphocyte count, Platelet count, Mean Corpuscular Volume (MCV) and CD4 count. In this study 26 (52%) were male and 24 (48%) were females. Majority of cases (50%) were between the age of 30 – 44 years. Decrease in CD4 count correlated with lymphopenia with CD4 count less than 500/µl in majority (88%). Anemia was the commonest abnormality (62%), predominantly normocytic normochromic type. Thrombocytopenia was the least noted (14%). This study reiterated that absolute lymphocyte count is the best correlated parameter with CD4 count in seropositive patients.

(3H)‒quinazolin‒4‒ones were reported for enhanced antibacterial, antiviral, antifungal and antimalarial activities with aryl and styryl substituents at position two and three respectively. In the present work, synthesis of some newly substituted (3H)‒quinazolin‒4‒ones starting from 2‒aminobenzoic acid and acetic anhydride producing 2‒methyl‒benzoxazin‒4‒one (Step‒I) has been undertaken. Replacement of ring oxygen from benzoxazin‒4‒one (step‒II) with nitrogen atom of 4‒chloro aniline produced first series of title compounds (QIa-QIk). In addition, 2-methyl group of benzoxazin‒4‒one was extended further as ethenyl (‒CH=CH‒) linkage joining to various substituted aldehydes (Step‒III). It has produced sufficient quantity of 2‒styryl‒3‒aryl‒(3H)‒quinazolin‒4‒ones (QIa‒QIk, Scheme I). In obtaining second series compounds (QIl‒QIt), identical approach was followed with replacement of benzoxazin-4-one ring oxygen with nitrogen atom of various substituted amines (Step‒II).There is extension of methyl group of benzoxazin‒4‒one as ethenyl group (‒CH=CH‒) joining 2‒chloro benzaldehyde. It has produced sufficient quantity of 2-[2-(2-Chloro-phenyl)-vinyl]-3-aryl‒(3H)‒quinazolin‒4‒one (QIl‒QIt, Scheme II). Structures of synthesized compounds were established by elemental analysis (C, H, N, O and X=halogen), FT‒IR, 1H NMR, 13C NMR and HR‒MS. In-vitro disk diffusion assay was performed using Gram‒positive bacteria Bacillus subtilis (NCIM2711), Staphylococcus aureus (NCIM2079), Gram‒negative bacteria Kleibsella pneumonia (ATCC 4352), Pseudomonas aeruginosa (ATCC27853) and fungi Candida albicans, Aspergillus niger. Ciprofloxacin and Griseofulvin were the positive control standards for bacteria and fungi respectively. Excellent antimicrobial activity (MIC=9.07‒10.54 µM x 10-3) was exhibited by compounds as (QId), (QIf), (QIg), (QIi), (QIj), (QIk), (QIl), (QIm), (QIn), (QIq), (QIr) and (QIs). Present study of (3H)‒quinazoline‒4‒ones will serve as an important path in the development and discovery of newer antimicrobial agents.

Macrocytosis in adults is defined as a red blood cell (RBC) mean corpuscular volume (MCV) >100 FL. Macrocytic anemia is generally classified into megaloblastic and non-megaloblastic anemia. The objective of this study was to assess haematological findings in patients of macrocytic anemia based on complete blood count and peripheral blood smear and to classify them based on clinical, serum vitamin B 12 and folic acid levels .The study was carried out over a period of one year at a tertiary care teaching hospital. 100 patients were selected on simple random sampling with MCV>99 FL and peripheral blood smear showing features of macrocytosis. Out of the 100 patients studied of macrocytic anemia, 55 percent had megaloblastic anemia and remaining 45 percent had non-megaloblastic anemia due to various causes. In our study, megaloblastic anemia was the most common cause of macrocytic anemia and among non- megaloblastic causes liver disorders like hepatitis was the most important cause.

Cutaneous larva migrans (CLM) is a tropical and subtropical parasitic infection caused by hookworm infection which inhabit in domestic pets such as cats and dogs. Larva found in infected soil, accidently penetrates the intact skin and causes lesions which are an erythematous, serpiginous, and extremely itchy. The reported case was clinically diagnosed as CLM had multiple lesions without complications and successfully treated with albendazole.

Acinetobacter has emerged as significant hospital pathogen involved in outbreaks of hospital infections, notoriously known to acquire antibiotic resistance to most of the commonly prescribed antimicrobials. Many risk factors are associated with Acinetobacter infections, especially in patients in intensive care unit (ICU). Acinetobacter species tend to be resistant to a variety of antibiotics and thus the infections are difficult to treat. This study aims to isolate Acinetobacter from various clinical samples and to determine its antimicrobial sensitivity pattern. The objectives of the present study were; 1) To isolate Acinetobacter species from various clinical samples. 2) To study their Antibiogram pattern of the Isolated Organisms. A total of 93 Acinetobacter species were isolated from various clinical samples. Identification of Acinetobacter was done on the basis of hemolysis on blood agar, growth at 42ºC, and oxidation fermentation test. Antibiotic susceptibility testing was done as per standard CLSI guidelines (2017). Maximum isolation of Acinetobacter species were from pus or wound swabs 57 (61.29%) followed by sputum and tracheal secretions 21 (22.58%) and urine 15 (16.12%) samples. Most of the strains were sensitive to imipenem (97%), piperacillin-tazobactam (91.39%), and getifloxacin (86%) whereas, maximum resistance was observed to co-trimoxazole (10.75%) and gentamicin (9.67%). Acinetobacter spp. has emerged as a major nosocomial pathogen. Broad-spectrum antibiotics should be used with caution and only after antibiotic susceptibility testing. Early identification and continued surveillance of prevalent organism will help prevent the spread of Acinetobacter in hospital environment. Empirical antibiotic policy should be determined for each hospital according to the resistance rates of that hospital setting.

Mobile phone usage has become an essential component of daily life. Several studies have raised concerns about the possible deleterious effects on the nervous system due to exposure of electromagnetic radiations. We aimed to study the effect of radiofrequency electromagnetic radiation (RF-EMR) on the spinal cord of albino rats. In the present study twenty-four adult albino rats of either sex weighing 180-200 grams each were divided into four groups: 1 control and 3 experimental and were exposed to RF-EMR via complete missed calls of 45 seconds duration each. Both the experimental and control groups were then sacrificed and spinal cord was isolated for tissue processing. The processed tissue was then stained (hematoxylin and eosin) and observed under light microscope. Light microscopy of the spinal cord showed the cellular size of the neuronal cells was reduced in dorsal and ventral horn interneurons, their nucleus was heterochromatic. Neurons were irregular, loosely arranged, darkly stained and decreased in size. Ventral horn cells of the spinal cord showed absent cytoplasm, heterochromatic nucleus with invisible nucleoli. Dose dependency with more radiation exhibit more changes in comparison to less exposed rats. From our findings, it is suggestive to protect the population living around base stations and users of mobile handsets. For this the government and regulatory bodies adopt safety standards which minimizes the hazardous effects of mobile radiation

Sclerosing rhabdomyosarcoma (SRMS) is a very rare subtype of rhabdomyosarcoma (RMS) and can lead to diagnostic difficulties especially if one is not advised of this variant. This entity was first described in 2000 by Mentzel and Katenkamp.Morphologically, it is characterized by an abundant hyalinized stroma that may erroneously lead to the diagnosis of extraskeletal chondrosarcoma, sometimes this stroma simulates a primary osteoid or vascular tumor. Thus, it can lead to confusion with osteosarcoma or angiosarcoma. We report here a case of SRMS mimicking a sclerosing epithelioid fibrosarcoma appearing in calves in a 55-year-old man. The tumor cells were arranged in nests, cords with sometimes a pseudovascular features. Immunostaining showed that the tumor was positive for Desmin, SMA and MyoD1, focally positive for myogenin and negative for CK, P63, EMA, S-100, H-caldesmon, CD34, CD31. Based on morphological discovery and immunostaining, he was diagnosed as an SRMS. This is the first case of SRMS to show a strong and diffuse α- SMA highlighting the risk of misdiagnosis as leiomyosarcoma.

A single renal artery to each kidney is present approximately 70% of individuals. The arteries vary in their level of origin and in their calibre, obliquity and in their precise relations. Near the renal hilum, each artery divides into anterior and posterior divisions and these divide into segmental arteries supplying the renal vascular segments. The materials were 35 formalin fixed cadavers irrespective of the sex which were used for the routine dissection of the undergraduate students in the Department of Anatomy. Single renal artery was observed in 71.42% originating from abdominal aorta. Accessory renal arteries were seen in 27.14% originating from abdominal aorta. Extrahilar branches arising from renal arteries were observed in 27.15% 0f the specimens studied. The knowledge of the possible variations of renal arteries is necessary during renal transplantation surgeries, urological procedures and angiography of the renal arteries.

Hematological disorders are frequent in all age groups and most of them present with anemia. Bone marrow aspiration is useful and cost effective diagnostic procedure for diagnosis of both neoplastic and non-neoplastic hematological diseases. This study was done to emphasize the crucial role of Bone Marrow Aspiration in diagnosis of hematological disorders. This was a retrospective study carried out in a period of 1 year (July 2016-August 2017). Bone marrow examination of 65 cases of suspected hematological disorders on peripheral blood smear was carried out and clinical history was recorded. We studied total 65 patients among them most common red blood cell pathologies were megaloblastic anemia (56%) followed by mixed erythroid hyperplasia (11%), iron deficiency anemia (6%), normoblastic maturation (6%). All the 5 patients of platelet disorders were diagnosed as Idiopathic Thrombocytopenic purpura (ITP). Among WBC pathologies Acute Leukemia (6%) and other Miscellaneous like aleukemic leukemia, leucoerythroblastic reaction & haemophagocytic lymphohistocytosis. Megaloblastic anemia was found to be the most common finding in RBC pathology, in WBC pathology acute leukemia was the most common and among platelets ITP.

Gallbladder is affected by a wide spectrum of diseases ranging from nonneoplastic lesions like congenital anomalies, gallstones and its complications, noninflammatory, inflammatory, to the neoplastic lesions .The aim of the study spectrum of histopathological changes in cholecystitis. The objectives were to study the histomorphology and frequency of various gall bladder diseases among specimens received and to correlate the various types of mucosal responses to different gallstone characteristic (like type, number, size volume and weight). Gall bladder specimen after cholecystectomy of patients who was admitted in ward surgery of BPS GMC, Khanpur Kalan, Sonepat.Place of study:-Department of Pathology, BPS GMC Khanpur Kalan, Sonipat. Study design- Prospective study. Out of 339 cases, two hundred and ninety seven (87.61%) patients studied were females, whereas 42 (12.39%) cases were males. Male to female ratio was 1:7.07. Out of the 339 cases, 234 (69.7%) had mixed stones, followed by pigment 44(13%) cases and cholesterol31 (9.1%) and 27 (8.1%) had no stones. 126 (37%) had single stone, nine had (3%) double and the remaining 195 (58%) had multiple stones. Conclusion: The histopathological spectrum of gallbladder lesions includes chronic cholecystitis and associated mucosal alterations and lesions like metaplasia, dysplasia and carcinoma. Variants of chronic cholecystitis such as xanthogranulomatous, granulomatous and follicular cholecystitis were also noted. To conclude, it was seen that the average weight, volume and size of the gall bladder significantly correlated in increasing order with cholecystitis, hyperplasia, metaplasia and carcinoma.

In order to make full use of data of stroke and find the potential characters, we use computer algorithm to model the stroke so as to comply with the evolution of stroke disease. In order to visual express the complex reason of stroke, we use complex network to model the stroke so as to express the complex reason and describe the relation of stroke structure and function. Computer model and complex network model should be combined with stroke standard method and custom index, which are more direct for clinical index and practice. Hybrid methods for research of stroke are a test to model, prevention, control and serve for stroke and other clinical disease
