Idiopathic peripartum cardiomyopathy is an uncommon malady disease. Making the diagnosis is often difficult and it is always necessary to exclude other prior heart disease and other causes of left ventricular dysfunction in pregnant women. Heart failure in these women ensues when the cardiovascular demands of normal pregnancy are further amplified when the common complications of pregnancy complications superimposed upon these underlying conditions that cause compensated ventricular hypertrophy. This may be aggravated by making a late diagnosis and providing inappropriate treatment. We experienced a 38-year-primigravida who has diagnosed with idiopathic peripartum cardiomyopathy and underwent elective cesarean section with general anesthesia.

The study was conducted to evaluate the effect of vitamin E and zinc supplementation on energy metabolites, lipid peroxidation, and milk production in peripartum Sahiwal cows. For this, thirty-two pregnant dry Sahiwal cows were selected at sixty days prepartum and divided into four groups viz control, $T_1$, $T_2$, and $T_3$ of eight each. Group $T_1$ were supplemented with zinc at 60 ppm/d/cow, group $T_2$ were supplemented with vitamin E at 1,000 IU/d/cow and group $T_3$ were supplemented with combination of vitamin E at 1,000 IU/d/cow and zinc at 60 ppm/d/cow during d 60 prepartum to d 90 postpartum. Blood samples were collected on d -60, -45, -30, -15, -7, -3, 0, 3, 7, 15, 30, 45, 60, 90, and 120 with respect to day of parturition and analysed for glucose, non esterified fatty acid, and thiobarbituric acid reactive substance. Body condition score was maintained significantly better (p<0.05) in $T_3$ than in the control, $T_1$ and $T_2$ groups. Overall glucose level was higher (p<0.05) in $T_3$ than control, $T_1$, and $T_2$ groups. Levels of nonesterified fatty acid, and thiobarbituric acid reactive substance were lower (p<0.05) in $T_3$ than control, $T_1$, and $T_2$ groups. Milk yield was higher (p<0.05) in $T_3$ than control, $T_1$, and $T_2$ groups. In conclusion, the present study indicated that the supplementation of vitamin E and zinc in peripartum Sahiwal cows enhanced milk production by reducing negative energy balance.

In 2011, a cluster of peripartum patients were admitted to the intensive care unit of a tertiary hospital in Seoul with signs and symptoms of severe respiratory distress of unknown etiology. Subsequent epidemiological and animal studies suggested that humidifier disinfectant (HD) might represent the source of this pathology. Epidemiological studies, animal studies, and dose-response analysis demonstrated a strong association between HD use and lung injuries. The diagnostic criteria for HD-associated lung injury (HDALI) was defined on the basis of the clinical, pathological, and radiological attributes of the patients. The clinical spectrum of HDALI appears to range from asymptomatic to full-blown acute respiratory failure, and some patients have required actual lung transplantation for survival. The overall mortality of the exposed population was not significant, although peripartum patients and children who were admitted to the intensive care unit did show high mortality rates. Persistent clinical findings such as diffuse ill-defined centrilobular nodules and restrictive lung dysfunction were observed in some of the survivors. The findings of this review emphasize the importance of assessment of the level of toxicity of chemical inhalants utilized in a home setting, as well as the need to identify and monitor afflicted individuals after inhalational injury.

The purpose of present study was to investigate the progesterone concentrations throughout gestation and peripartum period, and the return to the first estrus postpartum for improvement of reproductive efficiency in Korean native goats. The average length of gestation was 148 days(range : 144~154 days) and the average number of live births was 2 kids(range : 1~5 kids) in 12 Korean native goats. Progesterone concentrations were measured in blood samples taken from 12 goats every 5 days during gestation period. Plasma progesterone concentrations were 0.10 ng/ml at Day 0 of pregnancy and increased gradually until Day 20(6.58 ng/ml). Then they decreased slightly from Day 30 to 40(range : 4.32~4.82 ng/ml), increased again after Day 40 and remained thereafter until Day 140(range : 4.32~10.36 ng/ml). The progesterone levels declined sharply to basal levels at parturitum. Plasma progesterone concentrations during the pestpartum were 6.98 ng/ml at 10 days, 4.86 ng/ml at 6 days 3.18 ng/ml at 2 days before parturition, and 0.10 ng/ml at parturition, respectively. The basal levels were maintained until the first estrus postpartum. The mean intervals from parturition to the first estrus postpartum on the basis of progesterone determination and estrus detection were $100{\pm}64(mean{\pm}S.D.)$ days in 7 Korean native goats.

Lymphocytic hypophysitis is a rare inflammatory disease of the pituitary gland that is one of the cause of hypopituitarism. The majority of cases occur in women during the peripartum period, and it is rare in men. Testicular feminization syndrome is a genetic disorder presenting a 46XY karyotype, but a normal female phenotype. We report a case of lymphocytic hypophysitis in a 23-year-old woman with testicular feminization syndrome.

We experienced one case of pulmonary lymphangioleiomyomatosis in 26-year-old female patient. She had taken antituberculous medication under the impression of miliary tuberculosis on simple chest X-ray at peripartum period. On outpatient follow-up she complained of progressive exertional dyspnea in spite of medication. Through careful history taking and physical examination, high resolutional CT, and open lung biopsy she was diagnosed as pulmonary lymphangioleiomyomatosis combined with incomplete type of tuberous sclerosis. So, we presented the case with the brief review the literatures.

The objective of this study was to identify risk factors for repeat breeder dairy cows and their impact on reproductive performance. The characteristics of 1,504 cows, including their peripartum health, nutrition, production, and reproduction, were collected. Cows with metabolic disorder were significantly more likely (odds ratio [OR], 2.47; p < 0.001) and cows with clinical endometritis tended to be more likely (OR, 1.35; p < 0.1) to become repeat breeders than cows without metabolic disorder and clinical endometritis, respectively. Cows initially inseminated > 80 days after calving were less likely (OR, 0.78; p < 0.05) to become repeat breeders than cows initially inseminated ≤ 80 days after calving. As a result, repeat breeding in dairy cows resulted in a 90 day longer (p < 0.0001) mean interval from calving to pregnancy. In conclusion, postpartum metabolic disorder, clinical endometritis, and a short interval from calving to initial insemination were risk factors for repeat breeder dairy cows, resulting in a severely impaired reproductive performance.

The present study was conducted to find out the changes of progesterone and 20$\alpha$-dihydroprogesterone(20$\alpha$-OHP) levels before and after parturition, 4 pluriparous goats were offered for this experiment. Blood samples were taken from jugular vein on Days, 5, 3, 2 and 1 before parturition, the day of parturition, 1, 3, 5, 7 and 9 after parturition. The blood samples were centraifuged and stored at -2$0^{\circ}C$ until hormone assay. The serum levels of progesterone and 20$\alpha$-OHP were measrued by radioimmunoassay. The changes of serum progesterone level during peripartum period were characterized as a remarkable decrease. The progesterone level was 4.05$\pm$0.52ng/ml on 56 days before parturition and decreased to 2.24$\pm$0.38ng/ml on 1 day before parturition and 0.79$\pm$0.09ng/ml on the day of parturition and the basal level was maintained through 9 days of postpartum period. The serum level of 20$\alpha$-OHP during the peripartum period was 1.25$\pm$0.21ng/ml on 5 days before paturition and increased to 1.32$\pm$0.25 on 3 days and 1.59$\pm$0.24ng/ml on 1 day before parturition, and reached a peak level of 1.78$\pm$0.25ng/ml just prior to parturition and then decreased greatly to 0.31$\pm$0.03ng/ml on 1 day postpartum and the basal level was remained until 9 days postpartum. The high serum level of 20$\alpha$-OHP, which was peak just prior to parturition, was maintained for 2 days following the onset of remarkable decrease in the serum level of progesterone. From the above results, it was concluded that the enzyme 20$\alpha$-hydroxysteroid dehydrogenase (20$\alpha$-HSD) catalyzing the conversion of progesterone to a biologically inactive steroid, 20$\alpha$-OHP was active properly in the luteal cells in Korean native goats.

Peri-partum metabolic profile was evaluated in winter and summer calving, with 15 Murrah buffaloes in each seasonal group. In summer calvers, significantly lower values were observed for blood plasma urea nitrogen (BUN) at day 30 pre-partum (p<0.05), on calving day (p<0.05) and at all other stages (p<0.01); plasma non-esterified fatty acids (NEFA) values were significantly lower on day 30 pre-partum (p<0.01) and on day 60 post-partum (p<0.05). This was associated with significant reduction in days to first service (DFS) and service per conception (SPC) and an overall better reproductive performance in terms of service period, risk to first service on days 60, 90 and >90, and pregnancy risk to first service up to days 60 and 90. This may be attributed to better pre-partum nutritional status. Cervical and uterine involution were completed in fewer days, involutional changes took place at a faster pace and there were a lower number of abnormal involutional changes in winter compared to summer season. This may be attributed to better post-partum nutrition and less environmental stress. However, validation requires further targeted cohort investigation with a large sample size.

Incidence of retained placenta in dairy cows was investigated in 120 parturitions. Prior to calving, cows were allotted into four groups; 1) control, 2) the infection of Vitamin E (500 IU), 3) the injection of selenium (40 mg), and 4) the infection of Vitamin E (500 IU) and selenium (40 mg). Selenium (Se) and Vitamin E were injected intramusculary 20 d prior to the estimated calving date. No effects of Se or Vitamin E administration alone was observed for number of service per conception, conception rate, and estrus rate (p > 0.05). But the Vitamin E administration with Se significantly (p < 0.05) reduced the incidence of retained placenta and the days required for calving the first service. Incidence of retained placenta was not significantly (p > 0.05) influenced by parity, but it was significantly (p < 0.01) influenced by season, especially, increased during July and August. Concentration of Se in plasma was not significantly (p > 0.05) changed during peripartum period whether the treatment. The results of this study on retained placenta suggest that this disorder will be reduced by the administration of Se and Vitamin E prior to calving in dairy cows.
