Abstract The authors present the case of a 68-year-old woman with multiple growths of primary calvarial meningiomas. Histological examination revealed one tumor arising in the left parietal bone that showed some malignant aspects, including hypercellularity, cellular pleomorphism, necrotic foci, and some mitoses; the tumor partially had a meningotheliomatous pattern. Two other tumors in the right parietal bone were meningotheliomatous meningiomas without any malignant features. With a review of the literature, the pathogenesis of the multiplicity is discussed.

The authors report the case of a 23-year-old woman with café-au-lait spots and axillary and inguinal freckling who presented with a diploic chronic spontaneous hematoma of the left parietal bone. To the authors' knowledge, this case represents the first description of a diploic hematoma in a patient with stigmata of neurofibromatosis Type 1 unrelated to head trauma. Plain skull radiography showed an osteolytic lesion with well-circumscribed margins, corresponding to the hematoma, together with exuberant perilesional vascular markings. Angiography demonstrated an incidental aneurysm of the left supraclinoidal internal carotid artery and an unusual cortical venous drainage toward the diploic vessels. The blood flow of these vessels on the right hemicranium was sluggish and exhibited enlarged diploic venous lacunas. The authors hypothesize that the hematoma was formed by both an abnormal venous drainage toward the diploic vascular net, together with a vasculopathy that caused stenosis and obstruction of the normal drainage pathways from these vessels.

Bone defects are commonly seen in clinical practice. They are caused by different types of trauma, infections, congenital malformations and cancers. Current approaches to skeletal reconstructive surgery use biomaterials, autografts or allografts. The aim of this study was to analyze bone repair from histologic point of view. To study the repair of bone defects, we used two batches of Wistar mices (Lat Rattus Norvegicus). The 46 subjects under study were divided into two equal lots. In all subjects, a round defect with a diameter of 5 mm was surgically performed on the right and left parietal bone. In the 23 subjects in group I the defect in the left parietal bone was covered with alloplastic material (Osteoset) and the defect in the right parietal bone was not covered with osteoconductive, osteoinductive or osteogenic materials. Regarding subjects in group study II, none of the surgically created bone defects were covered with alloplastic materials. Euthanasia of the subjects included in the study was performed at 2 and 4 months respectively, at the time of surgery. Euthanasia, bone sampling and assembly for microscopic preparations were done on the same day. The histological analysis of a bone repair shows the direct correlation between the healing process and the addition of alloplastic materials (Osteoset).

Background: Every woman has the right to have children. Objective: This study aimed to investigate the Jurisprudence study of the importance of the role of a woman right to have a child. Methods: A review of the literature with keywords of motherhood. The viewpoints of the jurists, jurisprudent law, right contraception and breastfeeding, spiritual rewards, pregnant women, instinct of having a child and the Quran. The Information Centers such as Scopus and Iranmedex, Magi ran SID, Google Scholar, Science Direct, Pub med, and in the returns without any time limitations up to 2018. Therefore, Qur'anic verses based on the topic and authentic Hadith texts as well as authoritative, authentic scientific articles. Results: Narrations and Quran verses on greatness and respect of a mother show the importance of the maternal role. The maternal role is a fabulous facet of perfection of a woman and Islam has considered spiritual rewards for it. In the Quran, many biological changes such as pregnancy, childbirth, breastfeeding and taking care of a child and spiritual characteristics of mothers as the instinct seeking a child or generosity towards child have been mentioned. Islamic rules have a duty to extend this culture and aid mothers to achieve this right. Nobody can deprive a woman of it. Conclusion: In view of jurisprudent rules in Islam, if there is no limitation or natural barrier for a woman to have a child but her husband’s illogical unwillingness for having a child; this is, according to article 1130 of civil law, a kind of distress and embarrassment and the woman has the right to divorce.

Abstract Background This study aims at determining the biological effect of 75/25 w/w nano-hydroxyapatite/chitosan (nHAp/CS) scaffolds on bone regeneration, in terms of fraction of bone regeneration (FBR), total number of osteocytes (Ost), and osteocyte cell density (CD), as well as its biodegradability. Methods Two critical-size defects (CSDs) were bilaterally trephined in the parietal bone of 36 adult Sprague-Dawley rats (18 males and 18 females); the left remained empty (group A), while the right CSD was filled with nHAp/CS scaffold (group B). Two female rats died postoperatively. Twelve, 11, and 11 rats were euthanized at 2, 4, and 8 weeks post-surgery, respectively. Subsequently, 34 specimens were resected containing both CSDs. Histological and histomorphometric analyses were performed to determine the FBR, calculated as [the sum of areas of newly formed bone in lateral and central regions of interest (ROIs)]/area of the original defect, as well as the Ost and the CD (Ost/mm2) in each ROI of both groups (A and B). Moreover, biodegradability of the nHAp/CS scaffolds was estimated via the surface area of the biomaterial (BmA) in the 2nd, 4th, and 8th week post-surgery. Results The FBR of group B increased significantly from 2nd to 8th week compared to group A (P = 0.009). Both the mean CD and the mean Ost values of group B increased compared to group A (P = 0.004 and P < 0.05 respectively). Moreover, the mean value of BmA decreased from 2nd to 8th week (P = 0.001). Conclusions Based on histological and histomorphometric results, we support that 75/25 w/w nHAp/CS scaffolds provide an effective space for new bone formation.

Primary squamous cell carcinoma of the renal parenchyma is an extremely rare entity. The diagnosis of squamous cell carcinoma of the renal pelvis is usually unsuspected due to the rarity and inconclusive clinical and radiological features. Most of the patients are diagnosed at an advanced stage and are with poor outcome. Radical nephrectomy is the mainstay of the treatment. We reported a case of squamous cell carcinoma of the kidney in a 50-year-old female who presented with the right sided abdomen pain. The patient was treated with radical nephrectomy.

We report on a female patient who developed post-dural puncture headache (PDPH) after epidural analgesia for delivery. Treatment with epidural blood patch led to complete headache remission and the patient was discharged. Two days later the patient was readmitted with hemihypaesthesia and mild hemiparesis of the right side. Magnetic resonance imaging showed a small left parietal cortical haemorrhage probably following cerebral venous thrombosis (CVT). Coagulation screening detected heterozygous Factor V mutation. Headache is a common symptom of PDPH and CVT. Review of the literature revealed five patients in puerperal state, who developed CVT in close temporal relationship after blood patch treatment for PDPH. Change of headache character with loss of postural influence was reported frequently before diagnosis of CVT was confirmed. These findings may indicate a causal relationship.

✓ Two patients with benign intracerebral cysts are reported and a brief review of the literature is given. Although computerized tomography (CT) scanning is useful in detecting a variety of intracerebral cysts, the CT findings are not specific for any lesion. An exploratory operation with establishment of an adequate route of drainage and a histological examination of the cyst wall are mandatory in the management of patients with a progressive but benign lesion.

Introduction. Radiation recall dermatitis (RRD) is a phenomenon that occurs in previously irradiated areas shortly after administration of a chemotherapeutic agent. As the use of sorafenib expands, the incidence of radiation recall dermatitis induced by sorafenib will likely increase. Here, we report on a patient who developed RRD and describe his clinical characteristics along with a review of the literature. Case Presentation. Our patient was treated with palliative radiation therapy (RT) to a painful metastatic hepatocellular carcinoma lesion in the right forearm. He completed his radiation course with grade 1 dermatitis, which had resolved by the time he was started on sorafenib 400 mg twice daily 7 days afterwards. On the 21st day after RT, he presented with desquamation and erythema in the previously irradiated area of the right forearm, consistent with RRD. The sorafenib was discontinued and his symptoms subsequently resolved with conservative topical management. Conclusions. Although the pathophysiologic mechanism of sorafenib-related radiation recall dermatitis remains to be investigated, practitioners should be aware of its presence and management in order to improve clinical outcomes.
