In Ménière’s disease, the defective This is a disease of the inner ear characterised absorption by the sac is regarded as the by sudden and recurrent attacks of vertigo, cause of hydrops. Clinical Features Pathogenesis Paroxysmal attacks of vertigo with deafness and tinnitus mark the acute stage. The acute The basic histopathological change noted in attack typically starts with a feeling of aural these cases has been endolymphatic hydrops fullness followed by vertigo which is accom- (gross distension of endolymphatic system). The attack may last for a varying explaining its cause and in correlating it with period of time and may recur at short the symptomatology. Deafness is sensorineural in type, of causation of endolymphatic hydrops are grouped as follows: fluctuating, usually unilateral and progres- 1. As the disease progresses the deafness occurs because of disturbances of fluid becomes more pronounced and speech formation, which occur due to local distur- discrimination worsens. Another theory suggests that distension of patient’s hearing deteriorates and tinnitus the endolymphatic system occurs because becomes a constant feature. Recent studies of mechanical blockage and disturbed have shown a spontaneous remission rate of reabsorption. Proponents of this theory upto 71 per cent of cases within 8 years of maintain that the endolymph traverses the diagnosis.

Assessment Though this infant has DiGeorge syndrome and truncus arteriosus clonidine 0.1 mg on-line, the predominant features of her presentation are consistent with airway anomalies discount clonidine 0.1mg fast delivery, which are com- mon among DiGeorge patients buy 0.1mg clonidine free shipping. The suggestion of cardiac disease in this infant is more subtle, with a single S2 and systolic ejection click on physical examination, a low pO2 despite oxygen administration, and an absent thymus on chest radiograph. Management Infants who present with stridor require airway evaluation by an otolaryngologist, preferably before cardiac surgery, to allow for a better prediction of the post-operative course. This infant has significant tracheo- and bronchomalacia which will cer- tainly be expected to complicate her course in infancy. As pulmonary vascular resistance drops, pulmonary blood flow will 20 Truncus Arteriosus 247 increase and diuretics may be necessary. A genetics consult should be obtained to discuss implications of the syndrome and to counsel parents on genetic testing for future pregnancies. Awad and Ra-id Abdulla Key Facts • In single ventricle there is one ventricle receiving blood from both atria. Definition Single ventricle is a cyanotic congenital heart disease where there is one ventricle which receives blood from both atria. It is seen in about 1% of infants with congenital heart disease and 5 per 100,000 live births. Pathology Single ventricle is an arrest of development of an early embryological stage where the two atria communicate with the primitive ventricle (predecessor to the left ven- tricle) which communicates with an outlet chamber, called bulbus cordis (predeces- sor to the right ventricle). In a typical single ventricle, many of the features of this early developmental stages is noted, such as the double inlet or common atrioven- tricular communication between the two atria and single ventricle, the bulboven- tricular foramen, and the outlet chamber. Single ventricle is a lesion where both atria are connected to a single ventricle. This is either through two separate atrioventricular valves (double inlet ventricle) or a com- mon atrioventricular valve. The morphology of the single ventricle can be that of a left ventricle, a right ventricle, or a common ventricle (not typical of either ventricular mor- phology). Other congenital heart lesions as hypoplastic left heart syndrome and tricus- pid atresia are not considered single ventricle lesions although they have the same pathophysiology as single ventricle. In this lesion, the single ventricle is of a left ventricular morphology with a small outlet chamber (Fig. The communication between the single ventricle and the outlet chamber is known as the bulboventricular foramen. The single ventricle is posterior while the outlet chamber is anterior and to the left. With such an arrangement, the pulmonary artery emerges from the small outlet chamber, while the aorta emerges from the main (single) ventricle. On the other hand, the two great vessels could be transposed where the aorta is anterior and to the left (emerging from the outlet chamber) and the pulmonary artery is posterior and to the left (emerging from the single ventricle). Patients with heterotaxy may have single ventricle similar to what is described here; however, heterotaxy lesions are more complex as they include other patholo- gies such as situs abnormalities and systemic and/or pulmonary venous drainage. Pathophysiology Presentation, course, management and prognosis are determined by the presence and extent of pulmonary stenosis. Arrangement of great vessels does not signifi- cantly impact presentation or course since oxygenated and deoxygenated blood 21 Single Ventricle 251 Fig. In this type of single ventricle the tricuspid and mitral valves open into the single ventricle of left ventricular morphology, this is connected through an outlet chamber (primitive right ventricle). The pulmonary artery is anterior emerging from the rudimentary outlet chamber while the aorta is posterior emerging from the single ventricle already mix in the single ventricle and the oxygen saturation in both great vessels tend to be identical. However, the extent of pulmonary stenosis, if present, deter- mines the blood volume to the lungs. The greater the blood volume to the lungs, the milder is cyanosis and the worse is congestive heart failure. Lack of pulmonary stenosis will allow excessive pulmonary blood flow, leading to pulmonary edema and congestive heart failure. However, high pulmonary blood flow brings back more well oxygenated blood into the heart and thus minimizing cyanosis. Clinical Manifestations Clinical presentation varies with the extent of pulmonary stenosis. In cases of severe pulmonary stenosis pulmonary blood flow will be restricted and children will present early with cyanosis due to mixing of blood in the single ventricle and restricted pulmonary blood flow. The other extreme of clinical presentation is sec- ondary to little or no pulmonary stenosis resulting in excessive pulmonary blood flow which will cause pulmonary edema and limited or no cyanosis. Patients with excessive pulmonary blood flow will develop respiratory distress, easy fatigability and failure to thrive. S1: first heart sound, S2: second heart sound, A: aortic valve closure, P: pulmonary valve closure. A systolic click precedes a systolic ejection murmur heard over the left upper sternal border On physical examination cyanosis will be noted, more prominent in children with severe pulmonary stenosis.

Some statistical data showed that infertility may be owing to masculine reasons (approximately 1/3) or feminine reasons (2/3) clonidine 0.1 mg, including about 8% 17% women of childbearing age with an average incidence of infertility of about 10% clonidine 0.1 mg sale. Recently in Beijing buy generic clonidine 0.1 mg, at the “National Integrated Treatment of male and female infertility academic meeting”, experts stated that in China, the incidence of infertility is 15% 20%, mainly caused by social factors, working conditions and occupational factors, dietary factors, living habits and lifestyle factors, and genetic factors. These environmental and man-made factors, such as noise, extremely low-frequency electromagnetic fields, chemical exposure (occupational exposure), smoking, alcohol, drug abuse, mental stress, and psychological stress and burden have been identified to affect the human reproductive system, damage and reduce human fertility, as well as affect the initial stage of the embryo to a certain extent. In some cases, no specific cause could be detected, despite an extensive and complete evaluation. The relative prevalence of different infertility reasons varies widely among the patients (Table 14. Therefore, men and women with infertility should be aware of all these techniques and have adequate knowledge about the disease and its diagnosis, and actively seek medical attention. Acupunc- ture is a traditional, safe, and effective treatment used for curing some diseases in China, and of course, it is a good candidate for the treatment of female infertility. If a woman suffers from infertility induced by the functional, rather than a structural reason, she should be encouraged to try acupuncture treatment. A total of 10 out of 27 acupoints on the Kidney Channel are considered to be related to abnormal menstruation and reproduction. The spleen provides the material basis of the acquired constitution and has the function of maintaining the blood flow within the vessels. Among the 21 acupoints on the Spleen Channel, 5 acupoints are considered to be associated with menstrual disorders and reproduction. Among the 14 acupoints on the Liver Channel, 7 are observed to be related to menstrual disorders and infertility. Furthermore, Thoroughfare Vessel is considered to be the reservoir of blood, while Conception Vessel is in charge of the uterus and is the reservoir of Yin meridians. On the other hand, the Governor Vessel is considered to be the reservoir of Yang meridians. Thoroughfare, Governor, and Conception Vessels are all considered to originate from the uterus and subsequently develop into three different vessels. These three vessels can influence each other and play an important role in reproduction. About 1/4 of the acupoints on the Governor and Conception Vessels are considered to be associated with menstrual disorders and infertility. Hence, acupuncture for the treatment of infertility is observed to be closely related to Kidney Channel, Spleen Channel, Liver Channel, Thoroughfare Vessel, Governor Vessel, and Conception Vessel. Using a needle, the acupoint is perpen- dicularly punctured to about 2 3 cun, and the needle is retained for 20 30 min. Using a needle, the acupoint is perpen- dicularly punctured to about 2 3 cun, and the needle is retained for 20 30 min. From days 12 14 of the menstrual cycle, the woman with infertility can be administered with acupuncture treatment once per day, for 3 days. To promote the curative effect, acupuncture may be used every other day from days 8 12, and subsequently, every day from days 12 14. Two or three acupoints selected from the acupoints involved, can be used alternatively during every treatment. The long filiform needles are used to perpen- dicularly puncture the acupoint Zigong to about 3 4 cun, where the ovary located, to activate the function of the ovary. For patients with a delayed menstruation, the sessions of acupuncture treatment should be increased according to the patients’ menstrual cycle; usually, three cycles occur during one therapeutic course. During the period of treatment, the needling sensation should be transmitted toward both the sides of the lower abdomen. Endometrial thickness is a function of the uterine artery blood flow, and acupuncture may contribute to reduce the uterine artery impedance and consequently, increase the blood flow to the uterus. Hence, some researchers speculate whether acupuncture accompanying embryo transfer could increase the clinical pregnancy rate. In general, the above clinical data demonstrate that acupuncture could be an effective remedy for female infertility. However, the scientific mechanism of the therapeutic effect of acupuncture on infertility treatment needs to be elucidated, for which, we have presented a series of our study results along with those of the related published researches. However, many interesting and important questions, such as “why”, “how to”, and “which”, about the mechanism of acupuncture effect still needs to be addressed. Though these results are significant, they are inadequate to explain the mechanism of infertility treatment using acupuncture. In 1977, Mayer first reported that acupuncture analgesia may be involved in the production of brain endorphin and may be antagonized by the narcotic antagonist, naloxone.
