Se expone el caso de un recién nacido que desarrolló sepsis connatal precoz a Streptococcus agalactiae, con meningitis aguda supurada y osteoartritis de rodilla izquierda. Como factor de riesgo la madre no tenía realizado el exudado rectovaginal, pesquisa que detecta la colonización por estreptococo del grupo B (EGB). Se aisló el germen en hemocultivo y en líquido de punción articular. Recibió tratamiento antibiótico adecuado a la sensibilidad del microorganismo y según pauta de sepsis con meningitis, evolucionando favorablemente. En este trabajo se describe la epidemiología de la sepsis neonatal y los cambios ocurridos luego de la implementación de la profilaxis antibiótica en el preparto.

We hereby present the case of a newborn with early connatal sepsis due to Streptococcus agalactiae, with acute suppurative meningitis and left knee osteoarthritis. As a risk factor, the mother had not performed the rectus vaginal exudate screening that detects colonization by Group B Streptococcus (GBS). The germ was isolated in blood culture and in joint puncture fluid. The patient received germ-sensitive antibiotic treatment for meningitis sepsis and evolved favorably. This paper describes the epidemiology of neonatal sepsis and the changes that have occurred after the administration of the antibiotic prophylaxis during pregnancy.

Factores de riesgo de artrosis de rodilla, cadera o ambas en mujeres chilenas de mediana edad: un estudio de cohorte de tres décadas / Risk factors for the development of osteoarthritis in middle-aged women

BACKGROUND: Osteoarthritis (OA) is a health problem affecting millions of individuals worldwide. Aim: To evaluate risk factors for hip and knee osteoarthritis (OA) in women aged 40 to 59 years. MATERIAL AND METHODS: Analysis of a prospective cohort of 1159 women attending preventive health care programs and followed during 28 years. They underwent a clinical and laboratory evaluation from 1990 to 1993. The diagnosis of OA was retrieved from registries of a special program for osteoarthritis in 2020. RESULTS: Twenty four percent of participants developed osteoarthritis during the follow-up. At the beginning of the study and compared with women without OA, they were older (median [interquartile range or IQR]: 49.6 [8.5] and 47.2 [8.2] years respectively), had a higher body mass index (26.3 [5.3] and 25.1 [5.3] respectively), and a higher frequency of jobs with low qualification (76 and 62% respectively). The presence of type 2 diabetes mellitus, chronic hypertension, a previous history of alcohol or cigarette consumption, postmenopausal status and lipid and glucose blood levels did not differ between women with or without OA. Cox regression showed a final model that incorporates body mass index (hazard ratio (HR): 1.04; 95% confidence intervals (CI): 1.01-1.07), age (HR: 1.05; 95% CI: 1.03-1.08) and having an unqualified job (HR: 1.88; 95% CI: 1.43-2.47) as risk factors for OA. CONCLUSIONS: Obesity and the type of job are the most relevant risk factors found for OD: both may be modified with proper care.

Inhibition of diabetes mellitus-induced knee joint injury in rats by a combination of metformin and captopril / Inhibición de la lesión de la articulación de la rodilla inducida por diabetes mellitus en ratas mediante una combinación de metformina y captopril

SUMMARY: Osteoarthritis (OA) is an inflammatory disease that damages the joints and affects millions of people worldwide. The potential inhibitory effects of the antidiabetic drug metformin combined with captopril, the angiotensin-converting enzyme inhibitor, on diabetes-induced damage to the knee joint articular cartilage associated with the inhibition of glycemia, dyslipidemia, and inflammation has not been investigated before. Therefore, we induced diabetes in rats using high carbohydrate and fat diets and a single injection of streptozotocin (50 mg/kg). The protective group of rats was pre-treated with combined daily doses of metformin (Met; 200 mg/kg body weight) and captopril (Cap; 150 mg/kg body weight) for 14 days before diabetic induction and continued on metformin and resveratrol until the end of the experiment at week 12. Harvested tissues obtained from knee joints were prepared for basic histology staining with haematoxylin and eosin (H&E) and examined under light microscopy. Representative H&E images showed that OA was developed in the diabetic rats as demonstrated by a profound damage to the knee joints such as irregular eroded and a sharp decrease in the thickness of the articular cartilage surface and abnormal remodeling of the subchondral bone that were substantially ameliorated by Met+Cap. Met+Cap also significantly (p< 0.05) reduced blood levels of glucose, glycated hemoglobin (HbA1c), dyslipidemia, and the inflammatory biomarkers, high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-α) induced by diabetes. In addition, a significant (p≤ 0.0014) correlation between the articular cartilage thickness and the blood levels of glucose, HbA1c, triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein- cholesterol (HDL-C), and hs-CRP were observed. Thus, we demonstrate that Met+Cap effectively protect the knee joint against injuries induced secondary to diabetes in rats, possibly due to the inhibition of glycemia, dyslipidemia, and biomarkers of inflammation.

RESUMEN: La osteoartritis (OA) es una enfermedad inflamatoria que daña las articulaciones y afecta a millones de per- sonas en todo el mundo. No se han investigado los posibles efectos inhibidores del fármaco antidiabético metformina combinado con captopril, el inhibidor de la enzima convertidora de angiotensina, sobre el daño inducido por la diabetes en el cartílago articular de la articulación de la rodilla asociado con la inhibición de la glucemia, dislipidemia e inflamación. En este estudio fue inducida la diabetes en ratas con dietas altas en carbohidratos y grasas y una sola inyección de estreptozotocina (50 mg / kg). El grupo protector de ratas se pretrató con dosis diarias combinadas de metformina (Met; 200 mg / kg de peso corporal) y captopril (Cap; 150 mg / kg de peso corporal) durante 14 días antes de la inducción diabética. El tratamiento se continuó con metformina y resveratrol hasta el final del experimento en la semana 12. Los tejidos obtenidos de las articulaciones de la rodilla se prepararon para la tinción de histología básica con hematoxilina y eosina (H&E) y se examinaron con microscopía óptica. Imágenes representativas de H&E mostraron que la OA se desarrolló en las ratas diabéticas, como lo evidencia un daño profundo en las articulaciones de la rodilla, como la erosión irregular y una fuerte disminución en el grosor de la superficie del cartílago articular y remodelación anor- mal del hueso subcondral que fueron mejorados sustancialmente por Met + Cap. Met + Cap. También redujo significativamente (p <0.05) los niveles sanguíneos de glucosa, hemoglobina glicosilada (HbA1c), dislipidemia y los biomarcadores inflamatorios, proteína C reactiva de alta sensibilidad (hs-CRP), interleucina-6 (IL-6), y factor de necrosis tumoral alfa (TNF-α) inducido por diabetes. Además, una correlación significativa (p≤ 0,0014) entre el grosor del cartílago articular y los niveles sanguíneos de glucosa, HbA1c, triglicéridos (TG), lipoproteínas-colesterol de baja densidad (LDL- C), lipoproteínas de alta densidad-colesterol (HDL-C) ) y hs-CRP. Así, demostramos que Met + Cap protege eficazmente la articulación de la rodilla contra lesiones inducidas por diabetes en ratas, posiblemente debido a la inhibición de la glicemia, dislipidemia y biomarcadores de inflamación.

The association of anthropometric measures and osteoarthritis knee in non-obese subjects: a cross sectional study

OBJECTIVE: Body mass index (BMI) and knee osteoarthritis have a strong association, but other anthropometric measures lack such associations. To date, no study has evaluated non-obese knee osteoarthritis to negate the systemic and metabolic effects of obesity. This study examines the validity of the contention that BMI and other anthropometric measures have a significant relationship with knee osteoarthritis. METHODS: In total, 180 subjects with a diagnosis of knee osteoarthritis were recruited and classified according to Kellgren-Lawrence (KL) grades. Body mass index, mid-upper arm circumference, waist-hip ratio and triceps-skinfold thickness were recorded by standard procedures. Osteoarthritis outcome scores (WOMAC) were evaluated. RESULTS: (1) In both genders, the BMI was significantly higher for KL grade 4 than for grade 2; triceps-skinfold thickness was positively correlated with the joint space width of the tibial medial compartment. (2) In males, triceps-skinfold thickness significantly increased as the KL grades moved from 2 to 4; the significantly higher BMI found in varus aligned knees was positively correlated with WOMAC scores. (3) In females, the waist-hip ratio was significantly higher for KL grade 4 than for grade 2; a significant correlation was found between BMI and WOMAC scores. The waist-hip ratio was significantly associated with varus aligned knees and it positively correlated with WOMAC scores and with the joint space width of the tibial medial compartment. The mid-upper arm circumference demonstrated no correlation with knee osteoarthritis. CONCLUS'ON: This study validates the contention that BMI and other anthropometric measures have a significant association with knee osteoarthritis. Contrary to common belief, the triceps-skinfold thickness (peripheral fat) in males and the waist-hip ratio (central fat) in females were more strongly associated with knee osteoarthritis than BMI.

Osteoartrose em joelhos como fator limitante para a qualidade de vida em idosos / Osteoarthritis in knees as limiting factor for the quality of life in elderly

O envelhecimento tem sido motivo de preocupação e questionamentos constantes dentro de um contexto sócio-econômico e cultural mundial. No Brasil, devido o 2 chatamento da pirâmide demográfica consequente ao declive na taxa de mortalidade e também à diminuição na taxa de natalidade, a política de saúde tem sido levada a enfocar atenção integral à saúde do idoso dentro do sistema de saúde brasileiro, mesmo considerando suas limitações. Além disso, há um constante progresso em relação à busca de altemativas para que se melhorem as condições de vida ou de sobrevivência dos idosos. A osteoartrose (DA) em joelhos em indivíduos acima de 60 anos é fator límitante na qualidade de vida dos mesmos, impossibilitando-os de realizar suas atividades de vida diária de forma qualitativa e quantitativa. Sendo assim, nesta pesquisa foi estudada a prevalência de DA de joelho em uma amostra populacional de idosos residentes em Botucatu, São Paulo, com o intuito de possibilitar uma avaliação da sua autonomia em relação a esse aspecto. Para tanto, utilizou-se instrumento validado na literatura e adaptado para a nossa realidade. Foram entrevistados 355 idosos. O processo amostra foi o de sorteio dos idosos para prevalência desconhecida a partir de familias previamente selecionadas na amostragem sistemática, após atualização do censo do ano de 2002, com a localização das famílias (uma a cada quatro) através do mapa residencial da cidade. Essa população de idosos foi entrevistada três anos após o sorteio e, por este motivo, foi feita a reposição de perdas e óbitos de 80 idosos, estratificados por idade e sexo. Os idosos que na entrevista domiciliar referiram dor em joelhos foram encaminhados para exame clínico. Foi encontrado que 64% dos idosos referiram dor em joelhos e, destes, 98,6% apresentaram dor ou rigidez matinal e protocinética, com dificuldades acentuadas para realizar as suas atividades de vida diária...

Estudo comparativo entre a aplicação de crioterapia, cinesioterapia e ondas curtas no tratamento da osteoartrite de joelho / Comparison of cryotherapy, exercise and short waves in knee osteoarthritis treatment

A osteoartrite é a forma mais prevalente de doença articular. Os agentes físicos como o gelo e o calor podem combater o processo álgico quando corretamente indicados e utilizados. O objetivo deste trabalho foi a comparação de protocolos de tratamento fisioterapêutico, que envolveram o uso de cinesioterapia, crioterapia e ondas curtas, em indivíduos com osteoartrite de joelho. Em um estudo randomizado prospectivo cego foram tratados 25 indivíduos (25 joelhos), de 58 a 78 anos. GRUPO A: cinesioterapia e ondas curtas (n=9). GRUPO B: cinesioterapia e gelo (n=6). GRUPO C: cinesioterapia (grupo controle) (n=9). As variáveis analisadas foram: percepção subjetiva de dor (Borg), qualidade funcional (Lequesne), amplitude de movimento, flexibilidade e força muscular. A dor melhorou significativamente somente no grupo B, com qualidade funcional e flexibilidade positiva em todos grupos. O ganho de amplitude foi semelhante nos grupos B e C. Houve manutenção da força flexora nos grupos A e B e ganho nos indivíduos do grupo C. Na musculatura extensora observou-se ganho de força no grupo B e C e perda no grupo A. O melhor protocolo foi aquele que envolveu a aplicação de gelo e cinesioterapia para analgesia; não houve relação de ganho de amplitude, flexibilidade e força associado a termoterapia.

Osteoarthritis is the most prevalent form of joint disease. Physical agents such as ice and heat can fight the pain process, when correctly indicated and used. The objective of this study was to compare physiotherapy protocols involving the use of exercise, cryotherapy and short waves in individuals with knee osteoarthritis. In a prospective randomized study, 25 individuals were treated (25 knees), with ages ranging from 58 to 78 years. GROUP A: exercise and short-waves (n=9). GROUP B: exercise and ice (n=6). GROUP C: exercise alone (control) (n=9). Analyzed variables were: subjective perception of pain (Borg), functional quality (Lequesne), range of motion, flexibility and muscular strength. Pain significantly improved only for group B, with positive functional quality and flexibility in all groups. The improvement in range of motion was similar for groups B and C. Flexion strength was maintained for groups A and B, and strength gain for individuals in group C. In the extensors muscles, strength gain was seen in groups B and C, while strength loss was reported for group A. The best protocol was that one involving cryotherapy and exercises for pain relief. All groups showed improved functional quality; no correlation was found for range of motion gain, flexibility and strength gain associated with thermotherapy.

[Comparison of isolated anterior cruciate ligament tearing with anterior cruciate ligament tearing associated with displaced lateral femoral condyle fracture in knee arthrosis formation]

The etiology of posttraumatic arthritis has not been studied well. Although it has long been assumed that articular incongruity leads to post traumatic arthritis, clinical and basic sciences evidence to support such claim are not sufficient. On the other hand, the relationship of instability due to anterior cruciate ligament deficiency and Arthrosis has not been clearly defined and the relative importance of instability and incongruity is unknown. ACL tearing were created in right knees of 9 rabbits [group A] and ACL tearing and displaced lateral condylar fracture with 1 mm step were created in another 9 rabbits [group B]. After 6 months, osteoarthritis changes were compared between control knee and injured knee of each rabbit and between the two groups. In both groups, osteoarthritis changes in injured knees were more comparing to the control knee and in whole osteoarthritis changes were significantly more in group B compared to group A. The unstable knee due to ACL deficiency goes toward osteoarthritis faster than normal knee. Incongruity in unstable joint increases intensity of osteoarthritis changes. It shows the importance of achieving anatomic reduction in intra articular fractures before ligament reconstruction

Osteoarthritis of knees and obesity in Eastern Saudi Arabia

To find out the prevalence and relation between osteoarthritis of knees and obesity in Al-Ahsa region, Kingdom of Saudi Arabia [KSA]. The study included 243 male and female patients diagnosed with osteoarthritis of knees between June 2001 to March 2003. All patients were recruited from the Physical Therapy Department, King Fahd Hofuf Hospital, Hofuf, KSA. The clinical diagnosis was supported by plain x-rays of knees, and of other joint if needed. The weight and height of all patients were taken using one standard weight and height scale, and body mass index was also calculated and recorded. More than 90.53% of the patients referred with osteoarthritis of the knees were obese or overweight. The mean body weight of all patients was 84.61 kg and the mean height was 1.59 meters. Osteoarthritis of the knees was more common in obese female than male patients with a female to male ratio of 2.37:1. Obesity is a disease. The aim of all health professionals and others in the community should be directed to the prevention of this disease and its risk to develop multiple complications

Osteoarthritis of the knee in the Jordanian population

to describe the pattern of primary osteoarthritis of the knee in Jordanians, including age, sex, and relation to obesity and to assess the severity of pain and extent of disability in these patients. this is prospective study involving 74 patients with primary osteoarthritis of the knee, who met the American College of Rheumatology criteria for the classification and reporting of osteoarthritis of the knee. The patients were seen over the period between June 1999 and February 2000, in the Rheumatology and Internal Medicine Clinics at Prince Ali Hospital. These patients were evaluated in relation to age, sex, body weight, bilaterality, and the severity of pain, which was assessed according to Hernborg and Nilsson criteria. The effect of osteoarthritis on normal joint function and the extent of disability were assessed by a local modified classification used by other authors. the majority of patients [77.1%] were above 55 years of age. Most [75.7%] were females in a ratio of 3.1: 1 [females:male], and 90.5% were overweight and obese. Only four patients [males] had unilateral knee involvement. Almost half of the patients achieved four or more scores out of five, on the Hernborg and Nilsson criteria for pain. Most [86.5%] of the patients could walk outside unaided but with pain. Half of the patients could do their daily activity but with difficulty. the pattern of osteoarthritis of the knee in Jordanians is almost similar to that in other parts of the world. There are, however, some differences including the earlier age of onset of the disease, the earlier peak age of prevalence and the variation in the female to male ratio
