Abstract Background Malaria remains a major public health problem in Indonesian Papua, with children under five years of age being the most affected group. Haematological changes, such as cytopenia that occur during malaria infection have been suggested as potential predictors and can aid in the diagnosis of malaria. This study aimed to assess the haematological alterations associated with malaria infection in children presenting with signs and symptoms of malaria. Methods A retrospective study was performed by collecting data from the medical records of malaria patients at Sorong Regional General Hospital, Sorong, West Papua, Indonesia, both from outpatient and inpatient clinics, from January 2014 until December 2017. The laboratory profile of children suffering from malaria was evaluated. Results One hundred and eighty-two children aged 1 month to 18 years old were enrolled. The subjects were mostly male (112, 61.5%) with a mean age of 6.45 years (SD = 4.3 years). Children below 5 years of age suffered the most from malaria in this study (77, 42.3%). One hundred two subjects (56%) were infected with Plasmodium falciparum. Half of the enrolled subjects (50%) had haemoglobin level (Hb) between 5.1 and 10 gr/dL. A total of 41 children (53.2%) less than 5 years old suffered from P. falciparum infection. In the age group of 5–10 years, there were 34 children (57.6%) who suffered from P. falciparum, and in the age group > 10 years, 27 children (58.7%) suffered from P. falciparum infection. Only 4 subjects (5.2%) in the less than 5 years old age group had mixed malaria infection. Among eight predictors of the haematological profile, there were five predictors that were significantly associated with the diagnostic criteria, namely haemoglobin, haematocrit, leukocytes, platelets and monocytes (p < 0.05). Generally, clinical symptoms are not significantly associated with a malaria diagnosis, and only one variable showed a significant relationship, pale, with a P value of 0.001. Conclusions Children with malaria had changes in some haematological markers, with anaemia, low platelet count, white blood count, and lymphocyte count being the most important predictors of malaria infection in the study area. These markers could be used to raise suspicion of malaria in children living in high endemic areas, such as West Papua.

Background. Lynch Syndrome (LS) is characterized by germline mutations in the DNA mismatch repair (MMR) genesMLH1,MSH2,MSH6,andPMS2. This syndrome is inherited in an autosomal dominant pattern and is characterized by early onset colorectal cancer (CRC) and extracolonic tumors. The aim of this study was to identify mutations inMMRgenes in three Mexican patients with LS.Methods. Immunohistochemical analysis was performed as a prescreening method to identify absent protein expression. PCR, Denaturing High Performance Liquid Chromatography (dHPLC), and Sanger sequencing complemented the analysis.Results. Two samples showed the absence of nuclear staining for MLH1 and one sample showed loss of nuclear staining for MSH2. The mutations found inMLH1gene were c.2103+1G>C in intron 18 and compound heterozygous mutants c.1852_1854delAAG (p.K618del) and c.1852_1853delinsGC (p.K618A) in exon 16. In theMSH2gene, we identified mutation c.638dupT (p.L213fs) in exon 3.Conclusions. This is the first report of mutations in MMR genes in Mexican patients with LS and these appear to be novel.

ABSTRACT Background: The evaluation of collagen in the abdominal wall has been increasingly studied because of the relevance on collagen in the healing process after laparotomy. Aim: To evaluate the amount of collagen in the linea alba of patients undergoing laparotomic bariatric surgery and comparing with non-obese cadavers. Methods: Were evaluated 88 samples of aponeurosis from abdominal linea alba of 44 obese patients (obesity group) and 44 non-obese cadavers (control group). The samples were collected in 2013 and 2104, and were sorted according to age (18-30, 31-45 and 46-60), gender, BMI, waist and cervical circumference, and subcutaneous tissue thickness. Material for biopsy was collected from the supraumbilical region of the linea alba for immunohistochemical analysis differentiating collagen type 1 and type 3 and the 1/3 ratio. Image-Pro Plus pixel counting software was used to measure the amount of collagen. Results: The obesity group evidenced mean age 44.11±9.90 years; 18-30 age group had three (6.8%) obese individuals; 31-45 had 22 (50%) and 46-60 had 19 (43.1%). Females were present in 81.8% (n=36); BMI (kg/m²) was 48.81±6.5; waist circumference (cm) was 136.761±13.55; subcutaneous tissue thickness (cm) 4.873±0.916. Considering age groups, gender and BMI, there were statistical differences in all tests when compared with the cadavers. Conclusion: The amount of collagen in the linea alba above the umbilical region in the morbidly obese patients was smaller than in the non-obese cadavers in the same age group.

Sacral spinal cord ependymoma is an uncommon pathology. Most of the reported cases are consistent with a myxopapillary ependymoma histopathologic subtype. Non-myxopapillary ependymomas rarely occur in the sacral region. Most lesions are intradural; however, rare extradural cases can occur. We present the case of a 46-year-old female patient diagnosed with a grade II sacral extradural ependymoma, emphasising the importance of an interdepartmental case approach for diagnosis and management. Even though grade II ependymomas are considered low grade, the potential for recurrence and metastatic disease has been reported. There are no treatment guidelines for these rare tumours besides gross total resection.

Background: Meningiomas are slow growing intracranial and intraspinal neoplasms with a tendency to recur locally. WHO grades them as I (benign), II (atypical) and III (anaplastic) in order of their increasing aggressiveness, based on histological parameters and brain parenchymal invasion. Progesterone receptors (PR) are more prevalent amongst the lower grade meningiomas. The objective of this study was to determine the immunohistochemical expression of progesterone receptors in meningiomas of different grades.Material and Methods: A total of 100 cases were selected over a period of 2.5 years. Three to five microns’ thick sections stained with Hematoxylin and Eosin were examined microscopically by a team of two Histopathologists and graded into grades I, II and III, according to 2016 WHO classification criteria. Another section of the original tumor was stained with progesterone receptor antibody using the conventional immunoperoxidase method. Stained slides were than examined by the same team of Histopathologists and declared positive (if nuclear staining was observed in more than 10% of tumor cells) or negative. Statistical analysis was done using SPSS version 21.Results: Out of a total of 100 cases of meningioma, there were 79 cases of benign/typical WHO grade I, 15 cases of atypical/ WHO grade II and 6 cases of anaplastic/ WHO grade III tumor. PR status was positive in 89.8 % (71/79) of grade I meningiomas and 46.6 % (7/15) of grade II/Atypical meningiomas. The 06 cases of Anaplastic/WHO grade III tumors were negative for PR. There was a higher prevalence of Progesterone receptors in female patients (89.8%; 53/59) as compared to male meningioma patients (60.9%; 25/41).Conclusion: We observed a decreased expression of progesterone receptor in higher grades of meningioma in this study. It is an effort to explore conservative treatment options for inoperable lesions, as anti-progesterone therapy may hold a promise as a new treatment option in the near future.

Background/Aim. Renal carcinoma represents histologically heterogeneous group of malignant tumors, with various clinical aggressiveness. The frequency of p53 mutation in primal renal carcinoma is rare, although there are information about its heterogeneous accumulation. The loss of protein p16 expression in primal renal carcinoma is detected in 20-30% of the cases. The aim of this paper was to determine frequency of mutated protein p53 and expression of protein p16INK4a in renal carcinoma, to analyze their correlative relation and relation with the examined clinicopathological parameters. Methods. The examination included 12 patients (66.7% men, 33.3% women), with patohistologically verified renal carcinoma. Expression of mutated form of protein p53 and protein p16 was determined in tissue samples, by immunohistochemical analysis using of mice monoclonical antibodies produced by DAKO, Denmark. Results. In 9 (75%) of the cases was detected mutated protein p53, of whom 66.6% had higher histological gradus of tumor (G3-4) and higher pathological stadium of the disease (pT3a-b) at the same time. In 7 (58.3%) and 5 (41.7%) of the cases expression of protein p16, the loss of expression of protein p16 were detected respectively. A statistically significant positive correlation was determined between pathological stadium of disease (TNM) and the degree of tumor differentiation (G) (? = 0.834; p < 0.001), as well as between TNM and mitotic index (? = 0.622; p = 0.031). Conclusion. A mutated form of protein p53 exists in 75% of the cases with the renal carcinoma and 66.6% of then have higher histological gradus of tumor and higher stadium of tumor disease at the same time. Coexpression of mutated protein p53 and protein p16INK4a in renal carcinoma is not statistically significant and it is not in correlation with clinicopathological parameters. Immunohistochemical analysis of mutated protein p53 in renal carcinoma can have predictive significance.

Background. In Blacks, malignant melanoma (MM) is associated with greater morbidity and mortality compared to Caucasians. MMs with BRAF V600E mutation as well as those with loss of p16 protein expression are associated with aggressive behavior and worse prognosis. Objectives. We determined BRAF (V600E) mutation status and loss of p16 expression in MM cases in Lagos, Nigeria, and correlated these with histopathologic parameters and patients’ age. Methods. Forty-five cases of MM received between January 2005 and December 2014 in the Anatomic and Molecular Pathology Department of Lagos University Teaching Hospital were subjected to immunohistochemical studies to determine BRAF V600E mutation and p16 protein expression. These included cutaneous (n=37), musosal (n=3), and ocular MM (n=2) as well as lymph node metastatases (n=3). Results. BRAF (V600E) mutations were detected in 5/45 (11%) while 31/45 (69%) of the cases had loss of p16 expression. No statistically significant association was found between the BRAF (V600E) mutation, loss of p16 expression, and histologic parameters such as histologic variant, Clark level, Breslow thickness, and ulceration. Conclusion. BRAF (V600E) mutation was detected only in a small proportion of cases while loss of p16 expression occurred in most cases which also had high Clark level, high Breslow thickness, and ulceration.

Background: Hysterectomy is the most common gynecological surgery done in the females worldwide as it provides definitive cure to a wide range of gynecological diseases, both benign and malignant. The indications to perform this major surgery should always be justified and the pathology should be proved histopathologically. Histopathological analysis and review is mandatory to evaluate the appropriateness of the hysterectomy.Methods: A retrospective, longitudinal study was conducted in the Department of Obstetrics and Gynecology, UMAID Hospital, Dr. S.N. M.C. Jodhpur (Raj.) during October 2014 to March 2015.Total 105 cases were studied during this period. The study included all women undergoing planned abdominal hysterectomy. Data was recorded on proformas, including demographic characteristics and clinical features. Hysterectomy specimens were saved in 10% formalin and sent to the Department of Pathology. Histopathology reports were analyzed and compared with the indications of surgery to draw various informative conclusions.Results: Of 105 cases, 55(52.38%) were in the age group of 41 – 50, which comprised the commonest age group undergoing the surgery. Maximum women (95%) those underwent hysterectomy were multiparous. Most common preoperatively clinical diagnosis was leiomyoma uterus which was diagnosed clinically and sonographically in 51(48.57%) cases. On Histopathological examination, the commonest pathology, similar to clinical impression, was found to be Leiomyoma at 50.48% (n = 53). Adenomyosis (21.90%) was detected as Second most common pathology. Histopathological confirmation of pre-operative diagnosis was 89% for malignancy, 96% for fibroids, 100% for adenomyosis, 100% for pelvic inflammatory disease.Conclusions: There was a high correlation when the clinical diagnosis was a fibroid, adenomyosis and ovarian mass. Every hysterectomy specimen should be subjected to histopathological examination because it is mandatory for conforming diagnosis and ensuring optimal management, in particular of malignant disease.

Background: Peyronie’s disease is a localised connective tissue disorder that involves the tunica albuginea of the penis. Although long recognised as an important clinical entity of the male genitalia, the aetiology of this disease has remained poorly understood. Methods: The epidemiology and clinical presentation of Peyronie’s disease during a 10-year period was evaluated. Results: Forty-two men with Peyronie’s disease from Chandigarh, India were reviewed retrospectively. The prevalence of Peyronie’s patients was 1.97/1000 patients. Their ages ranged from 23 to 70 years. Most of them presented during the early phase of the disease. The most common presenting complaint was penile curvature in 34 (80.95%) followed by pain on erection in 28 (66.66%). History of penile trauma was revealed by four (9.52%) patients. Among the risk factors, hypercholesterolemia (60%), hypertension (33.3%) and asymptomatic hyperuricemia (28.34%) were the most common. Twenty-two patients with Peyronie’s disease were studied by ultrasonography. Ultrasonogram was more accurate than clinical assessment in delineating the extent of lesions. In one-third of the patients, sonography demonstrated the plaques to be more extensive than had been detected by clinical examination. Conclusions: The clinical symptoms and signs in our study were, in general, similar to those found in the previous studies. Higher incidence of hypertension and diabetes in patients with Peyronie’s disease may also be to an extent due to patients being in an older age group.
