Idiopathic transient osteoporosis of the hip is a rare but underdiagnosed condition. It is common in middle-aged men and pregnant women. The exact etiology is unknown. Aim. We present a 52-year-old man presented with progressively increasing pain left hip for two months. Description of the case. The radiograph showed osteoporosis localized to the proximal femur. Magnetic resonance imaging showed bone marrow edema. He was diagnosed as a case of idiopathic transient osteoporosis of the left hip (ITOH) after ruling out other causes. He was treated nonoperatively with analgesics and rest. He was given daily calcium and monthly ibandronate 150mg. His symptoms subsided after 3 months. There was no recurrence of symptoms. Conclusion. We present this case to describe the clinical, radiological features, diagnosis, and treatment of ITOH. Idiopathic transient osteoporosis is a rare condition. It is often not diagnosed because of a lack of awareness and also being a self-limiting condition. The radiogram may be normal. So a high index of suspicion is needed for its diagnosis.","PeriodicalId":15378,"journal":{"name":"临床和实验医学杂志","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85393719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Description of the case. This article describes a case of a 63-year-old man and his wife, a 60-year old woman who were admitted to the emergency department with a few days’ history of gastrointestinal symptoms. Both patients presented with the digestive symptoms of nausea, diarrhea and loss of appetite. They denied abdominal pain and the loss of smell or taste. Due to suspicion of SARS-CoV-2 infection a nasopharyngeal swabs of both patients was taken. The results of real- time reverse transcriptase-polymerase chain reaction were positive.

Osteoarthritis of the knee is the most common presentation of osteoarthritis with prevalence between 12% and 35% of general population and is considered the leading cause of musculoskeletal disability in the elderly population worldwide. Aim. The study compared efficacy of kneading massage and pulsed ultrasound on pain, joint stiffness and difficulty in knee osteoarthritis (KOA). Material and methods. Fifty subjects with radiological evidence of KOA participated in the study. They were randomly allocated into kneading massage group (KMG) (25) and Ultrasound group (USG) (25). KMG received kneading massage for 7 minutes while USG received pulsed mode ultrasound for 15 minutes. Treatment was twice in a week for six weeks. Pain intensity (PI), joint stiffness and difficulty were assessed pre, 3rd and 6th weeks of treatment session with semantic differential scale and WOMAC. The data were analyzed using descriptive and inferential statistics, alpha level was set at 0.05 Results. There was a significant difference in present PI (F=11.45,P=0.001) and stiffness (F= 11.32, P=0.003) in USG. There was a significant reduction in PI (F=7.95, P=0.001) and joint stiffness (F=8.86, P=0.003) in KMG. At the 6th week, there was a significant differences in PI (t=12.23,P=0.000) and stiffness (t=8.08, P=0.000) when USG (3.00+0.4, vs 7.14+ 1.49) was compared with KMG (3.16+0.5 vs 7.50+1.5).

Hijab is a head cover worn by some Muslim women in the presence of any adult male outside of their immediate family, which usually covers the head, neck and chest. It is strictly forbidden to Muslim woman to unveil any single hair of her head, so they use many pins around the head to fix their Hijab. Often, while using pins they are self-pricked. Aim. The main aim of our work is to reveal a new cause of lymphadenopathy, which is not known till now. Material and methods. Retrospective study during the past five years among seventy-five female outpatients, visited our Oral and Maxillofacial clinic in dental department. Our data was collected according to medical history of patients; all female patients with cervical lymphadenopathy were using (A hijab). Results. Data collected of 75 female patients. Lymphadenopathy causes were various. Most of these causes resulted from nonspecific lymphadenitis (67 patients), 4 tuberculosis, 2 lymphoma, 2 cat scratch disease. Aetiology of 67 nonspecific lymphadenitis was 40 patients of dental cause, 10 of sore throat, 7 of acne vulgaris, 3 of mild facial injuries, and 7 of (Hijab pin pricks). Conclusion.

Although there are various reasons for intrauterine growth restriction (IUGR), the main cause is inadequate utero- placental and feto-placental circulation. Aim.

Material and methods. 15 with IUGR and 35 normal newborn, who were born at the 34th gestational week or over included into the study. Doppler ultrasonography (US) measurements were performed. The ratio of pulsatility index/resistive index (PI/ RI) from MCA, umbilical artery (Umb), DA was determined. Neonatal characteristics such as Apgar scores, neonatal intensive care unit (NICU) requirement, weight and sex were also recorded. Results. In the IUGR group, mean MCA/DA RI-PI, MCA/UmB RI-PI were 0.88±0.19, 0.86±0.28, 1.22±0.18 and 1.55±0.39, respectively.

Entero-bladder fistula (fistula entero-vesicalis) is a pathological connection between the lumen of the gastrointestinal tract and the bladder. Entero-bladder fistulas are not a common condition. The main reason for the formation of entero- bladder fistulas are intestinal diseases occurring within the intestinal loop adjacent to the bladder resulting in the formation of an abnormal channel, the connection between the above structures Aim. The aim is to present the causes of the fistulas can be divided into congenital and acquired (intestinal infection, cancer, Crohn’s disease, resulting from trauma and iatrogenic). Clinical manifestations of the biliary-bullous fistulae may be from the digestive or urinary tract. The most characteristic ailments are pneumaturia, fecuria, urge to urinate, frequent urination, lower abdominal pain, hematuria, urinary tract infection. Description of the case. The article discusses the case of a patient with Leśniowski-Crohn disease complicated with a bladder- fistula. The treatment of entero-bladder fistulas is primarily surgical, it consists in resection of the fistula together with resection of the affected intestine and bladder wall fragment. Conclusion. The test confirming the presence of an entero-bladder fistula is a test with oral administration of poppies, although it happens that the test result may be negative, especially in the case of a bladder-follicular fistula.
